                  2.2.1  Immediately  prior to the  Effective  Date,  Parent  or

                  2.2.2 As soon as  practicable  after the Effective  Date,  the
Surviving  Corporation  shall  cause the  Paying  Agent to mail to each  Company
Shareholder a letter of  transmittal  and  instructions  for use (the "Letter of
Transmittal") in effecting the surrender of certificates  representing shares of
Common   Stock   outstanding   immediately   prior   to   the   Effective   Date
("Certificates").  The Letter of Transmittal shall be in customary form, include
provisions  stating that delivery shall be effected,  and risk of loss and title
to such  Certificates  shall pass, only upon delivery of the Certificates to the
Paying  Agent,   provide  instructions  for  effecting  the  surrender  of  such
Certificates  in exchange  for the Merger  Consideration  and provide such other
provisions  as  Parent  may  reasonably   specify  (including  those  provisions
described in this Section 2.2). Upon surrender of a Certificate for cancellation
to the Paying Agent, together with such Letter of Transmittal, duly and properly
executed,  the  holder of such  Certificate  shall be  entitled  to  receive  in
exchange  therefore  (A) the amount  equal to (i) the number of shares of Common
Stock  represented  by such  Certificate  multiplied  by (ii)  the  Cash  Merger
Consideration,  and (B) one Combined  Deferred  Payment  Right for each share of
Common Stock represented by such Certificate.  If the Cash Merger  Consideration
(or any portion  thereof) is to be delivered to any person other than the person
in whose name the Certificate representing shares of Common Stock surrendered in
exchange therefor is registered on the record books of the Company,  it shall be
a condition  to such  exchange  that the  Certificate  so  surrendered  shall be
properly  endorsed  or  otherwise  be in proper form for  transfer  and that the
person  requesting  such exchange  shall pay to the Paying Agent any transfer or
other taxes required by reason of the payment of such  consideration to a person
other  than the  registered  holder  of the  Certificate  surrendered,  or shall
establish to the satisfaction of the Paying Agent that such tax has been paid or
is not applicable.  Combined  Deferred  Payment Rights shall not be evidenced by
certificates  and shall not be  transferable,  except as  required  by law.  All
payments,  if any, with respect to the Combined Deferred Payment Rights shall be
paid to the persons in whose name the  Certificates  are registered on the books
of the Company immediately prior to the Effective Date. No interest will be paid
or will accrue on the cash payable  upon  surrender  of any  Certificate.  Until
surrendered as contemplated by this Section 2.2, each Certificate  shall, on and
after the Effective Date, be deemed to represent only the

                                        4

right to receive,  upon surrender of such Certificate,  the Merger Consideration
with respect to the shares of Common Stock represented thereby.

                  2.2.3 On and  after  the  Effective  Date,  there  shall be no
transfers  on the stock  transfer  books of the  Company of the shares of Common
Stock which were outstanding  immediately prior to the Effective Date. If, after
the Effective  Date,  Certificates  are presented to the Surviving  Corporation,
they shall be  cancelled  and  exchanged as provided in this Section 2.2. In the
event of a  transfer  of  ownership  of  shares  of  Common  Stock  which is not
registered  in the  transfer  records of the  Company,  payment may be made with
respect  to  such  share  of  Common  Stock  to  such a  transferee  only if the
Certificate  representing such shares of Common Stock is presented to the Paying
Agent,  accompanied  by all  documents  required  to  evidence  and effect  such
transfer and evidence that any applicable stock transfer taxes have been paid.

                  2.2.4 In the  event any  Certificate  shall  have  been  lost,
stolen or destroyed,  upon the making of an affidavit of that fact by the person
claiming such  Certificate  to be lost,  stolen or destroyed and, if required by
the  Surviving  Corporation,  upon the  posting by such person of a bond in such
amount as the Surviving  Corporation may reasonably  direct as indemnity against
any claim that may be made  against it with  respect  to such  Certificate,  the
Paying  Agent  will  issue  in  respect  of  such  lost,   stolen  or  destroyed
Certificate, the Merger Consideration with respect to the shares of Common Stock
represented thereby.

                  2.2.5  Upon  the  determination  by the  Paying  Agent  that a
shareholder  is an  Objecting  Shareholder  and not a Company  Shareholder,  the
Paying Agent shall deliver to the Surviving Corporation that amount equal to (i)
the number of shares of Common Stock held by such Shareholder multiplied by (ii)
the Cash Merger  Consideration.  Any portion of the Payment  Fund which  remains
unclaimed  by any of the  Company  Shareholders  for nine (9)  months  after the
Effective  Date shall be delivered to the Surviving  Corporation  upon demand of
the  Surviving  Corporation,  and the  holders of shares of Common  Stock  shall
thereafter look only to the Surviving Corporation for payment of their claim for
the Cash  Merger  Consideration  in  respect  of their  shares of Common  Stock.
Neither Parent,  Acquisition Corp nor the Surviving  Corporation shall be liable
to any holder of shares of Common Stock for any Merger  Consideration  delivered
to a public official pursuant to any applicable  abandoned property,  escheat or
similar law.

                  2.2.6  Parent or the Paying  Agent shall be entitled to deduct
and withhold from the consideration otherwise payable pursuant to this Agreement
to any holder of a Certificate  surrendered  for the Merger  Consideration  such
amount as Parent or the Paying  Agent is  required to deduct and  withhold  with
respect to the making of such  payment  under the  Internal  Revenue  Code as of
1986, as amended (the "Code"),  or any provision of any state,  local or foreign
tax law. To the extent that amounts are so deducted and  withheld,  such amounts
shall be treated for all  purposes of this  Agreement as having been paid to the
holder of such Certificate.

                  2.2.7 In the case of 4,000  shares  of  Common  Stock  held of
record by Martin  Enowitz or his assigns  which the Company  represents  are the
subject of a dispute between  Besicorp Group Inc.  ("BGI") and Mr. Enowitz,  the
Merger Consideration shall be placed in the existing escrow

                                        5

<PAGE>


with respect to such 4,000 shares, and appropriate provision will be made in the
Paying Agent agreement for the holding of Combined  Deferred  Payments,  if any,
and the Cash  Merger  Consideration  payable in  respect of such  shares in such
escrow, pending resolution of the dispute.

                  2.2.8 The fees and  expenses of the Paying  Agent will be paid
from earnings on the Payment  Fund.  To the extent  earnings on the Payment Fund
are insufficient to pay such fees and expenses,  such fees and expenses shall be
paid by the Surviving  Corporation.  The Company and Parent and Acquisition Corp
agree that any  interest  earned on the Payment Fund and not utilized to pay the
fees and  expenses  of the Paying  Agent will be  transferred  to the  Surviving
Corporation.

         2.3   Adjustment  of  Merger   Consideration.   In  the  event  of  any
reclassification,  stock split, stock dividend or other general  distribution of
securities, cash or other property (other than the Distribution) with respect to
shares of Common Stock (or if a record date with respect to any of the foregoing
should  occur) on or after the date of the Initial  Agreement and on or prior to
the Effective Date, appropriate and equitable adjustments,  if necessary,  shall
be made to the calculation of the Merger Consideration and all references herein
shall be deemed to be to the Merger Consideration as so adjusted.

         2.4      Combined Deferred Payments.

                  2.4.1 The parties  hereto agree that the Company  Shareholders
shall  receive  from the  Surviving  Corporation  for each share of their Common
Stock, in addition to the Cash Merger  Consideration,  an additional  payment or
payments  ("Deferred  Payments")  on the  Deferred  Payment  Dates  equal in the
aggregate to (i) the amount in the Deferred Payment Fund on such date divided by
(ii) the number of shares of Common  Stock held of record  immediately  prior to
the Effective  Date by the Company  Shareholders.  The  "Deferred  Payment Fund"
consists  of the  sum of all  Adjustments  (net  of  corporate  taxes  for  such
Adjustments) less all amounts  previously  distributed from the Deferred Payment
Fund to the Company Shareholders. The "Adjustments" equal the Adjustment Amounts
multiplied  by a  fraction,  the  numerator  of which is the number of shares of
Common Stock held of record by the Company Shareholders immediately prior to the
Effective  Date and the  denominator of which is the sum of the number of shares
of Common  Stock  held of  record by the  Company  Shareholders,  the  Objecting
Shareholders and the Ineligible Shareholders  immediately prior to the Effective
Date and the number of Management  Restricted  Shares which have been  cancelled
pursuant to Section 4.9 hereof prior thereto.  The  "Adjustment  Amounts" equals
all  proceeds  received by the  Company,  the  Surviving  Corporation  and their
Subsidiaries  (provided that in the case of proceeds  received by an entity that
is less than  wholly  owned,  directly  or  indirectly,  by the  Company (or the
Surviving Corporation),  such proceeds shall be multiplied by a percentage equal
to the percentage of the entity owned,  directly or  indirectly,  at the time of
receipt of such  proceeds by the Company (or the Surviving  Corporation))  on or
after the date of the Initial Agreement and on or before the latest of (i) March
22,  2004,  (ii) the date of the release by the escrow  agent for the March 1999
Escrow  Agreement  of  all  of  the  March  1999  Escrow  Funds  and  (iii)  the
disposition,  pursuant  to a final  and  non-appealable  judgment  of a court of
competent  jurisdiction,  including  the payment of all monies  required by such
disposition, of the lawsuit encaptioned "Besicorp, Ltd., plaintiff, against Alan
R. Kahn, James Lichtenberg, Vee Hockmeyer, Paul Vannucci, Andrew Jurun,

to the following:  (i) amounts, if any, released from the March 1999 Escrow Fund
pursuant to Section 4 of the March 1999  Escrow  Agreement  (other than  amounts
released  pursuant to the  Instructions,  (ii) amounts  received with respect to
each of the  litigation  claims of the Company,  the Surviving  Corporation  and
their  Subsidiaries  with respect to matters  arising before the Effective Date,
less the Company's  expenses  (including  reasonable SG&A but excluding expenses
which are  funded  with  monies in the March  1999  Escrow  Fund (the  "Excluded
Expenses"))  incurred  and  paid  following  the date of the  Initial  Agreement
directly  related to any such claim for which amounts have been received,  (iii)
amounts received with respect to the sale of the Company's  interests,  directly
or indirectly,  except for debt financing for development capital purposes which
might have an equity carried interest in a Foreign Development  Project, in each
of the Foreign Development  Projects (unless such Foreign Development Project is
sold  along  with the  Empire  Project  in which  case the  proceeds  are not an
Adjustment  Amount)  pursuant to agreements  entered into on or before the first
anniversary of the Effective Date, less the Company's  expenses (other than SG&A
and  Excluded  Expenses)  incurred  and paid  following  the date of the Initial
Agreement  directly related to such Foreign  Development  Project,  (iv) amounts
received by Beta  Partnerships,  Inc.  "Beta") and  distributions  received from
Kamine  Besicorp  Natural  Dam  L.P.,  ("Natural  Dam")  (other  than an  amount

1999 and  disclosed  under  "Liquidity  and Capital  Resources" in Item 2 of the
Company's  Form 10QSB for the period  ended June 30,  1999) and any other  funds
that are distributed as a result of partnership interests in existence as of the
date of the Initial  Agreement or the  Effective  Date and (v)  amounts,  net of
expenses (other than SG&A and Excluded Expenses) incurred and paid following the
date of the Initial  Agreement  directly related to distributions as a result of
Hydro-Credits,  distributed  as  a  result  of  Hydro-Credits  (other  than  the
distribution  with  respect to Glen Park  Associates  scheduled  for on or about
September  30,  1999);  provided  however that the  Adjustment  Amount shall not
include the proceeds of any transfer of assets by the Surviving  Corporation  or
any wholly owned  Subsidiary  of the Surviving  Corporation  to any wholly owned
Subsidiary of the Surviving  Corporation  or to any entity (a "Related  Entity")
consisting solely of shareholders of the Surviving  Corporation on the Effective
Date,  if, and only if (i) the Related  Entity  shall  consent in writing to its
assumption of the obligation to make Deferred  Payments in the manner  described
in Section 2.4.4 (without the right to defer payments if the amount accrued on a
Deferred  Payment Date is less than $90,000) with respect to such asset and (ii)
the Surviving  Corporation  will be required to guarantee  the Related  Entity's
payment  of all  amounts  it is  required  to pay  to the  Company  Shareholders
pursuant to this  assumption.  The  Surviving  Corporation  shall  segregate the
Deferred  Payment  Fund and invest its proceeds in a separate  interest  bearing
money market account at Bankers Trust Company or any other nationally recognized
financial  institution,  and all interest on the Deferred  Payment Fund shall be
added to such Fund.

                           2.4.2 The Surviving Corporation  shall  make Deferred
Payments to the Company  Shareholders  (ii) annually on each June 1st commencing
on June 1, 2000  and  ending  on  the last June 1st, immediately  prior  to  the
Deferred  Payment Termination Date (each, a "Deferred  Payment Date"), (provided
that if on any Deferred Payment Date the amount in the Deferred Payment

                                        7

<PAGE>


Fund is less than $90,000,  no Deferred  Payment shall be made on such date) and
(ii) on the  Deferred  Payment  Termination  Date.  All such  Payments  shall be
accompanied  by a notice  stating  in  reasonable  detail the  proceeds  and the
expenses that were deducted.

                          2.4.3 If the Surviving Corporation or a Related Entity
transfers, sells or  otherwise  assigns,  directly  or indirectly,  any  of  the
Underlying  Assets, the assignee (the "Assignee") of such Underlying Asset shall
be required to consent in writing  to its  assumption of the obligation  to make
Deferred  Payments (without the right to defer payments if the amount accrued on
a Deferred Payment Date is less than $90,000) with  respect to  such  Underlying
Asset other than the obligation to make the  Deferred Payment, if any, resulting
from  proceeds received by the Surviving Corporation or Related Entity from such
assignment (which  Deferred Payment resulting from such Proceeds, shall  be  the
obligation of the Surviving Corporation or Related Entity, as applicable) in the
manner described in Section 2.4.4.

                           2.4.4  Payments by a  Related Entity or  an  Assignee
(the "Payor") shall be made on Deferred  Payment Dates as follows: such payments
shall be equal to (i) the amount in the Substitute Deferred Payment Fund on such
date divided by  (ii) the number  of  shares of  Common  Stock  held  of  record
immediately   prior  to  the  Effective  Date  by the Company Shareholders.  The
"Substitute  Deferred  Payment Fund"  consists of  the  sum  of  all  Substitute
Adjustments  (net of all corporate taxes for such Adjustment)  less all amounts
previously  distributed from the Substitute Deferred Payment Fund to the Company
Shareholders.  The  "Substitute Adjustments"  equal  the  Substitute  Adjustment
Amounts multiplied by a fraction, the numerator of which is the number of shares
of Common Stock held of record by  the Company  Shareholders  immediately  prior
to the  Effective  Date and the denominator of which is the sum of the number of
shares  of  Common  Stock held  of record  by  the  Company  Shareholders,   the
Objecting  Shareholders  and  the Ineligible  Shareholders  immediately prior to
the  Effective  Date and  the  number of Management Restricted Shares which have
been cancelled  pursuant to Section 4.9  hereof  prior  thereto. The "Substitute
Adjustment Amounts"  equals all proceeds received by the Payor  on or  after the
date of the Initial Agreement and on or before Deferred Payment Termination Date
with respect to the following: (i) amounts, if any, released from the March 1999
Escrow  Fund  pursuant to Section 4 of the  March  1999  Escrow  Agreement, (ii)
amounts received with respect to each of the  litigation claims assigned by  the
Company with respect  to  matters  arising  before the Effective  Date, less the
expenses  of  the  Company and Payor (including  reasonable SG&A  but  excluding
Excluded Expenses) incurred and paid following the date of the Initial Agreement
directly related to any such claim with  respect  to any such  claim  for  which
amounts  have been  received, (iii) amounts received with respect to the sale of
the  Payor's interests,  directly or indirectly,  except for  debt financing for
development  capital  purposes which  might have an equity carried interest in a
Foreign Development Project, in each of the Foreign Development Projects (unless
such Foreign Development Project is sold along with the Empire  Project in which
case the proceeds are not a Substitute Adjustment Amount) pursuant to agreements
entered into on or before the first anniversary of the Effective  Date, less the
expenses  of  the  Company and  Payor (other  than SG&A and  Excluded  Expenses)
incurred and paid  following the date of the Initial Agreement  directly related
to  such  Foreign  Development Project,  (iv)  amounts received  by  Beta  and
distributions  received from Natural Dam (other than an amount anticipated to be
received by Beta  from  Natural Dam on or before December 31, 1999 and disclosed

period  ended June 30,  1999),  and any other  funds that are  distributed  as a
result of  partnership  interests  in  existence  as of the date of the  Initial
Agreement  or the  Effective  Date and (v)  amounts,  net of the expenses of the
Company and Payor  (other than SG&A and  Excluded  Expenses)  incurred  and paid
following the date of the Initial Agreement directly related to distributions as
a result of Hydro-Credits,  distributed as a result of Hydro-Credits (other than
the distribution with respect to Glen Park Associates  scheduled for on or about
September 30, 1999).  If a Payee (or assignee of a Payee) attempts to assign any
Underlying  Asset,  the assignee of such  Underlying  Asset shall be required to
consent in writing to its assumption of the obligation to make Deferred Payments
(without  the right to defer  payments  if the amount  accrued  on a  Substitute
Deferred  Payment Date is less than  $90,000)  with  respect to such  Underlying
Asset other than the obligation to make the Deferred Payment,  if any, resulting
from proceeds  received by the assignor  from such  assignment  (which  Deferred
Payment  resulting from such Proceeds,  shall be the obligation of the assignor)
in the manner described above.

                           2.4.5     Escrow Fund  Payments. The  parties  hereto
agree that the Company Shareholders shall receive for each share of their Common
Stock, in addition to the Cash Merger  Consideration  and the Deferred  Payments
pursuant to Deferred Payment Rights, an  additional payment or payments ("Escrow
Fund Payments") to be paid by the Paying Agent equal in the aggregate to (i) the
amount in the Escrow Fund  Payment  Distributions  received by the  Paying Agent
pursuant  to the  Instructions,  and  not yet distributed  by the Paying  Agent,
divided by (ii) the number of shares of Common Stock held of record  immediately
prior to the Effective Date by the Company Shareholders.


                  2.5 Management  Restricted Shares.  The Merger  Consideration,
including  the Cash  Merger  Consideration  and the  Combined  Deferred  Payment
Rights, with respect to all Management Restricted Shares, if any, the vesting of
which has not been accelerated pursuant to the Incentive Plan, and which are not
subject to Substitution Agreements, shall be placed in escrow with the Surviving
Corporation and such Merger  Consideration  shall be held in accordance with the
terms of the Restricted  Stock Grant  Agreements with respect to such Management
Restricted Shares.

                                   ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

         3.1 General Statement.  The parties only make the  representations  and
warranties  to each other which are set forth in this  Article III or in Exhibit
4.7(a).

         3.2  Representations  and  Warranties  of  the  Company.   The  Company
represents  and warrants to Parent and  Acquisition  Corp that as of the date of
the  Initial  Agreement  and,  in the case of  Section  3.2.2,  the date of this
Agreement:

                  3.2.1 Organization and Authority. Each of the Company and each
of its Subsidiaries: (i) is a corporation or partnership duly organized, validly
existing and in good standing  under the laws of the State of its  organization;
and (ii) has all necessary corporate or partnership


                                        9

<PAGE>


power and  authority  to  conduct  its  business  as now being  conducted  or as
proposed to be conducted  through  Closing.  Each of the Company and each of its
Subsidiaries is duly qualified as a foreign  corporation and is in good standing
in each  jurisdiction  in which the  nature  of its  business  or the  nature or
location of its assets require such qualification except where the failure to be
so qualified would not have a Material Adverse Effect.

                  3.2.2  Authority   Relative  to  this  Agreement  and  Related
Matters. The Board of Directors of the Company (the "Board"),  at a meeting duly
called and held has (A)  determined  that the  Agreement and Merger are fair to,
and in the best  interests of, the Company and its  shareholders,  including the
Company  Shareholders,  (B) adopted and approved this Agreement,  the Merger and
the Distribution,  and (C) resolved to submit to the shareholders of the Company
and recommend to the  shareholders  of the Company that they adopt and authorize
the  Agreement  and the  Merger.  The  Company  has  full  corporate  power  and
authority, subject to shareholder adoption and authorization with respect to the
Agreement,  to enter into and perform this Agreement,  and the other  agreements
(the  "Transaction  Agreements")  to be  entered  into in  connection  with this
Agreement, the Merger and the Distribution to which it is a party. The execution
and delivery of this Agreement and each of the other  Transaction  Agreements by
the Company and the performance by the Company of its obligations  hereunder and
thereunder have been (or, in the case of Transaction  Agreements not yet entered
into,  will be) duly authorized and approved by all requisite  corporate  action
other than the approval of the holders of at least  one-half of the  outstanding
shares of Common Stock  voting at the Meeting  with respect to the Merger.  This
Agreement has been and, when executed,  each of the other Transaction Agreements
will have been, duly executed and delivered by duly  authorized  officers of the
Company and each constitutes, or will constitute when so executed and delivered,
a valid, legal and binding obligation of the Company  enforceable  against it in
accordance with its terms, except as enforceability may be limited by applicable
equitable principles or by bankruptcy, insolvency,  reorganization,  moratorium,
or  similar  laws from  time to time in  effect  affecting  the  enforcement  of
creditors'  rights  generally.  The affirmative  vote of the holders of at least
one-half of the  outstanding  shares of Common  Stock voting at the Meeting with
respect to the adoption and  authorization  of the  Agreement and the Merger are
the only votes of the  holders of any class or series of the  Company's  capital
stock necessary to approve the Merger.

                  3.2.3  Capitalization.  The  authorized  capital  stock of the
Company  consists  solely of 5,000,000  shares of Common  Stock,  and  1,000,000
shares of preferred stock, par value $0.01 per share ("Preferred  Stock"). As of

which  are  entitled  to  vote  as a  class,  including  (a)  13,850  Management
Restricted  Shares  which  will not vest as a result of the Merger and (b) 5,824
shares of Common  Stock  reserved  for  issuance  upon the delivery of shares of
common  stock of BGI in  connection  with the March 1999 Merger  (the  "Reserved
Shares"),  (ii) 100  shares of Common  Stock  were held in the  treasury  of the
Company,  (iii) no  options,  warrants or similar  rights to purchase  shares of
Common Stock ("Stock  Options") were outstanding and (iv) no shares of Preferred
Stock  were  outstanding.  There  are no other  shares of  capital  stock of the
Company  authorized,  issued or outstanding.  All of the  outstanding  shares of
Common Stock (other than the Reserved Shares which, upon their issuance, will be
fully paid and  nonassessable)  have been validly  issued and are fully paid and
nonassessable  subject to the restrictions on the Restricted Shares set forth in
the agreements for such Restricted

                                       10

<PAGE>


Shares.  There  are  no  subscriptions,   options,  stock  appreciation  rights,
warrants, rights (including preemptive rights), calls, convertible securities or
other  agreements  or  commitments  of any  character  relating to the issued or
unissued capital stock or other securities of the Company obligating the Company
to issue, or register the sale of, any securities of any kind.

                  3.2.4 Brokers. No broker,  finder,  investment banker or other
Person is entitled to a broker's  commission,  finder's fee, investment banker's
fee or similar payment from the Company in connection with the Merger other than
amounts  payable to Josephthal & Co., Inc.  ("Josephthal")  pursuant to a letter
agreement dated June 9, 1999 between Josephthal and the Company.

                  3.2.5 Fairness  Opinion.  The Company has received the written
opinion of Josephthal  (the "Fairness  Opinion") dated September 22, 1999 to the
effect that, as of such date, the Merger Consideration to be received by Company
Shareholders  for each share of Common  Stock is fair from a financial  point of
view.  The Company has provided a true and correct copy of the Fairness  Opinion
to Parent.  The Company is  authorized  by  Josephthal to include a copy of such
opinion in the proxy  statement  relating to the  Agreement and the Merger to be
approved at the Meeting (as amended or supplemented, the "Proxy Statement").

                  3.2.6 Full  Disclosure.  The  representations,  warranties and
statements of the Company in this  Agreement or contained in any schedule,  list
or document delivered pursuant to this Agreement are true, complete and correct.
The  copies  of  all  documents  furnished  by  the  Company  pursuant  to or in
connection with this Agreement are true, complete and correct.

                  3.2.7 SEC  Filings.  None of the  information  provided by the
Company  and  included  in the  Proxy  Statement,  the  Rule  13e-3  transaction

By-Laws  of the  Surviving  Corporation  shall  provide  indemnification  to the
Indemnified  Persons on terms, in a manner,  and with respect to matters,  which
are no less favorable to the Indemnified Persons than the Company's  Certificate
of Incorporation and By-Laws, as in effect on the date of the Initial Agreement,
and further agree that such indemnification  provisions shall not be modified or
amended except as required by law, unless such modification or amendment expands
the rights of the Indemnified Persons to indemnification.

Person  wishes to make a claim for  indemnification  against  the  Company  with
respect to any matter which may give rise to a claim for  indemnification,  then

shall set forth with reasonable specificity all facts relating to such claim for
indemnification).  The Company  shall pay to the  Indemnified  Person any amount
required to be paid  pursuant to this Section 4.4.3 within 90 days after receipt

been  incurred  or come due as the Company may  reasonably  request,  unless the
payment  of such  amount is  contested  prior to the  expiration  of such 90 day
period by notice to the  Indemnified  Person.  If such payment is so  contested,
then such  payment  shall be made within 30 days after the first to occur of the
following:  (i) the Company and the  Indemnified  Person  agreeing in writing to
make such  payment or (ii) such  payment has been  declared due in a judgment or
award entered against the Company by a court of competent jurisdiction.

                   (c) If any third person shall  notify an  Indemnified  Person
with respect to any matter which shall give rise to a claim for  indemnification

to this  Section  4.4.3,  then the  Indemnified  Person shall notify the Company
thereof  promptly (which notice shall set forth with reasonable  specificity all
facts relating to such claim for indemnification). Within thirty (30) days after
receipt of written  notice of a  particular  matter,  the Company may assume the
defense of such matter;  provided  however,  that:  (i) the Company shall retain
counsel  reasonably  acceptable to the Indemnified  Person, and (ii) the Company
shall not,  without the prior written consent of the  Indemnified  Person (which
shall not be  unreasonably  withheld),  enter  into any  settlement  of a claim,
consent to the entry of any judgment with respect to a claim, or cease to defend
such  claim,  if  pursuant  to or as a result  of such  settlement,  consent  or
cessation,  injunctive or other  equitable  relief shall be imposed  against the
Indemnified  Person or if such  settlement  does not  expressly  unconditionally
release the Indemnified Person from all liabilities and obligations with respect
to such claim,  with  prejudice.  If,  within the thirty  (30) day  period,  the
Company  does not  assume  the  defense  of such  matter  which the  Company  is
obligated to defend, the Indemnified Person may defend against the matter in any
manner that it reasonably may deem  appropriate.  The Company shall bear all the
reasonable  fees and expenses of  defending  any such  matter.  The  Indemnified
Person may  participate  in the  defense of such  claim with  co-counsel  of its
choice, provided, however, that the fees and expense of the Indemnified Person's
counsel shall be at the expense of the Indemnified  Person unless the Company is
liable for the Losses  forming the basis of such claim pursuant to Section 4.4.3
and the Company has failed to assume the defense and employ  counsel as provided
herein.

                  (d) No amount  shall be payable by the Company with respect to
claims for indemnification  asserted pursuant to this Section 4.4.3 in excess of
(i) the  limitations of the Current  Insurance  Policy and (ii) the  deductibles
contained in such Policy.

fail to make any payment of  principal or of interest on this Note when due; (b)
Maker shall fail,  beyond any applicable  notice,  grace or cure period, to make
any  payment or shall fail to keep,  observe,  comply  with or perform any term,
provision,  covenant, warranty, agreement,  condition or undertaking on its part
required to be paid,  complied with or performed or observed,  by the provisions
of  this  Note,  the  Security  Agreement,  the  Mortgage  or any  of the  other
agreements,  documents or instruments  executed and/or delivered by the Maker to
the Payee in connection  with the  execution of this Note,  the Mortgage and the
Security Agreement;  (c) Maker shall (i) commence any case,  proceeding or other
action  under  any  existing  or future  law of any  jurisdiction,  domestic  or
foreign,  relating  to  bankruptcy,  insolvency,  reorganization,  or  relief of
debtors,  seeking to have an order for  relief  entered  with  respect to it, or
seeking to  adjudicate it a bankrupt or  insolvent,  or seeking  reorganization,
arrangement, adjustment, winding-up, liquidation,  dissolution,  composition, or
other relief with respect to its debts;  (ii)  commence any case,  proceeding or
other action seeking  appointment of a receiver,  trustee,  custodian,  or other
similar  official for it or for all or any  substantial  part of its assets;  or
(iii) make a general  assignment  for the  benefit of its  creditors  (provided,
however,  that Payee  shall not have taken any action to cause Maker to take any
of the actions set forth in this clause);  (d) there shall be commenced  against
Maker by any  person  (other  than  Payee or an  affiliate  of Payee)  any case,
proceeding or other action of a nature  referred to in clause (c) above that (i)
results  in the  entry of an  order  for  relief  or any  such  adjudication  or
appointment, or (ii) remains undismissed, undischarged, or unbonded for a period
of thirty (30) days; or (e) there shall be commenced against Maker by any person
(other  than  Payee or an  affiliate  of Payee) any case,  proceeding,  or other
action seeking  issuance of a warrant of attachment,  execution,  distraint,  or
similar process  against all or any substantial  part of its assets that results
in the entry of an order for any such relief  that shall not have been  vacated,
discharged,  or stayed or bonded pending appeal within thirty (30) days from the
entry thereof;  (f) Maker shall take any action in furtherance of, or indicating
its consent to,  approval of, or  acquiescence  in, any of the acts set forth in

not have taken any action to cause Maker to take any of the actions set forth in
this clause);  or (g) Maker shall generally not, or shall be unable to, or shall
admit in writing its inability  to, pay its debts as they become due  (provided,
however,  that Payee acknowledges that neither Maker's seeking and obtaining the
Loan  nor any  statements  contained  in  Company  Filings  (as  defined  in the
Agreement)  shall  constitute an admission that Maker is unable to pay its debts
as they become due.

         If an Event of Default shall have occurred and be continuing, Payee may
declare this Note  immediately due and payable in full, both as to principal and
accrued  interest  without any further notice to Maker, and Payee may proceed to
exercise  and enforce  any and all of the rights and  remedies  available  to it
hereunder  and at law or in equity.  Payee  shall not be required to look to any
security  given for the  payment of the sums  payable  under this Note,  but may
proceed against the Maker  immediately upon the maturity or acceleration of this
Note or the occurrence of an Event of Default hereunder.

                                       2

<PAGE>


         No remedy  conferred  upon or reserved or  available  to Payee shall be
exclusive  of any other  remedy or remedies  available to it, but each and every
remedy shall be cumulative  and shall be in addition to every such remedy now or
hereafter  existing  at law or in equity.  No delay or  omission  on the part of
Payee  to  exercise  any  right  or  power  arising  upon  the   occurrence  and
continuation of any Event of Default shall impair any right or power of Payee or
be  construed  to be a waiver by Payee of such  Event of  Default.  Any right or
power of Payee may be exercised  from time to time and as often as may be deemed
expedient by it. Maker shall pay Payee's  costs of  collection  and  enforcement
(including  reasonable attorney's fees) in connection with each Event of Default
under this Note.  If any Event of Default shall have occurred and for as long as
any Event of Default shall be continuing,  all amounts due pursuant to this Note
shall bear interest at the rate of fifteen (15%) percent per annum (the "Default
Rate") and not the Agreed Rate.


                  2. OPTIONAL PREPAYMENTS.  Maker shall have the right to prepay
all or any part of this Note at any time or from time to time without penalty.

                  3. MANDATORY PREPAYMENT. In the event Maker sells its business
or  substantially  all of its assets  (other than in a  reorganization  in which
Maker only receives stock of a company that is required to file reports pursuant
to the  Securities  Exchange  Act of 1934,  as  amended,  or as a result  of the
consummation of the transactions  contemplated by the Agreement),  or issues its
securities in a public offering,  the unpaid  principal  balance of the Note and
any interest due thereon  shall be paid,  to the extent of the cash  received by
Maker, in full  simultaneously  with the closing of the sale or public offering.
In the  event  that  Maker  in a  reorganization  receives  stock  and  cash the
prepayment shall apply only to the extent of cash received.

                  4. WAIVER OF JURY TRIAL. THE MAKER IRREVOCABLY  WAIVES ANY AND
ALL RIGHTS THE MAKER MAY HAVE TO A TRIAL BY JURY IN ANY  ACTION,  PROCEEDING  OR
CLAIM OF ANY NATURE RELATING TO THIS NOTE, ANY DOCUMENTS  EXECUTED IN CONNECTION
WITH THIS NOTE, THIS MORTGAGE OR THE SECURITY AGREEMENT.  THE MAKER ACKNOWLEDGES
THAT THE FOREGOING WAIVER IS KNOWING AND VOLUNTARY.  THE MAKER ACKNOWLEDGES THAT
IT HAS READ AND UNDERSTOOD ALL THE PROVISIONS OF THIS NOTE, INCLUDING THE WAIVER
OF JURY TRIAL, AND HAS BEEN ADVISED BY COUNSEL AS NECESSARY OR APPROPRIATE.

                  5. MAXIMUM RATE OF INTEREST.  NOTHING  CONTAINED  HEREIN OR IN
ANY INSTRUMENT OR TRANSACTION  RELATED HERETO,  SHALL BE CONSTRUED OR OPERATE AS
TO  REQUIRE  THE MAKER OR ANY  PERSON  LIABLE  FOR THE  PAYMENT OF THE LOAN MADE
PURSUANT HERETO, TO PAY INTEREST, OR ANY CHARGE IN THE NATURE OF INTEREST, IN AN
AMOUNT OR AT A RATE  WHICH  EXCEEDS  THE  MAXIMUM  RATE OF  INTEREST  ALLOWED BY
APPLICABLE  LAW  RELATING  TO USURY.  IN THE EVENT  THAT PAYEE  DETERMINES  THAT
CHARGES AND FEES INCURRED IN CONNECTION

                                       3

<PAGE>


WITH THIS NOTE MAY UNDER SUCH  APPLICABLE LAWS CAUSE THE INTEREST RATE HEREON TO
EXCEED THE MAXIMUM RATE ALLOWED BY LAW, THEN SUCH INTEREST SHALL BE RECALCULATED
AND ANY  AMOUNT IN  EXCESS OF THE  MAXIMUM  INTEREST  PERMITTED  BY LAW SHALL BE
APPLIED  TO REDUCE  THE  PRINCIPAL  AMOUNT OF THE NOTE.  IT IS THE INTENT OF THE
PARTIES  HERETO  THAT UNDER NO  CIRCUMSTANCES  SHALL  MAKER OR ANY OTHER  PERSON
LIABLE  FOR THE  PAYMENT OF THIS NOTE BE  REQUIRED  TO PAY,  NOR SHALL  PAYEE BE
ENTITLED TO COLLECT,  ANY INTEREST  WHICH IS IN EXCESS OF THE MAXIMUM LEGAL RATE
PERMITTED  UNDER SUCH APPLICABLE LAW. PAYEE MAY, IN DETERMINING THE MAXIMUM RATE
OF INTEREST  ALLOWED UNDER  APPLICABLE  LAW, AS AMENDED FROM TIME TO TIME,  TAKE
ADVANTAGE OF ANY STATE OR FEDERAL LAW, RULE OR REGULATION IN EFFECT FROM TIME TO
TIME  WHICH MAY GOVERN  THE  MAXIMUM  RATE OF  INTEREST  WHICH MAY BE  RESERVED,
CHARGED OR TAKEN. MAKER AND PAYEE HAVE AGREED THAT NEW YORK LAW SHALL GOVERN ALL
CONSIDERATIONS AND DETERMINATIONS WITH REGARD TO USURY.

                  6.       MISCELLANEOUS.

                  (a) No delay or  omission  of Payee to  exercise  any right or
power  arising  hereunder  or by law shall  impair any such right or power or be
considered to be a waiver of any such right or power,  nor shall Payee's  action
or inaction  impair any such right or power.  The Maker agrees to pay on demand,
to the extent permitted by law, all costs and expenses  incurred by Payee in the
enforcement  of its rights with respect to this Note and any  security  therefor
(including  pursuant to the  Security  Agreement  and the  Mortgage),  including
without  limitation,  reasonable  fees and expenses of Payee's  counsel.  If any
provision  of this  Note is  found  to be  invalid  by a  court,  all the  other
provisions of this Note will remain in full force and effect.

                  (b) The  Maker and all  other  parties  who at any time may be
liable hereon in any capacity, jointly or severally,  waive presentment,  demand
for  payment,  protest  and notice of dishonor  of this Note and  authorize  the
holder hereof, without notice, to grant extensions in the time of payment of and
changes in the rate of interest pursuant to Section 5 hereof on any moneys owing
on this  Note.  The Maker  also  waives  all  defenses  based on  suretyship  or
impairment of collateral.

                  (c)  This  Agreement  shall  be  binding  upon  Maker  and its
successors and assigns.

                  (d) Any notice or request hereunder shall be given by (a) hand
delivery,  (b) overnight  courier,  or (c) registered or certified mail,  return
receipt  requested.  Any notice or other  communication  required  or  permitted
pursuant to this Note shall be deemed given (i) when personally delivered to any
party or any officer of the party to whom it is  addressed,  (ii) on the earlier
of  actual  receipt  thereof  or three (3) days  following  posting  thereof  by
certified or registered  mail,  postage  prepaid,  or (iii) upon actual  receipt
thereof when sent by a recognized overnight delivery service.

documentation  for  recordation  under  the  UCC or any  other  applicable  law,
statute, rule or regulation and with any appropriate governmental authority, and
otherwise to act in Debtor's name and place with respect to the Collateral,  all
with the same legal force and effect as if such acts were  performed  by Debtor.
Debtor  authorizes  Secured  Party  to  file  any  such  financing   statements,
continuation  statements and amendments  thereto without the signature of Debtor
and, upon receipt of notice of filing,  Debtor shall reimburse Secured Party for
all applicable filing fees and related expenses.  Secured Party shall deliver to
Debtor a copy of any statement  filed pursuant to this  paragraph  promptly upon
filing.

                  6.       Remedies and Sale.

                           (a)      In addition to any rights and remedies now
or hereafter granted under applicable  law, and not by way of  limitation of any
such rights and remedies, upon  the  occurrence  of an Event of Default but only
so long as an Event of Default is continued, Secured Party shall have all of the
rights and remedies of  a secured  party under the Uniform  Commercial  Code  as
enacted  in  any applicable jurisdiction  in addition to the rights and remedies
provided  herein. Secured Party shall have the right, without further notice to,

                  (ii)     to file any claim, commence,  maintain or discontinue
                           any  actions,  suits or other  proceedings  deemed by
                           Secured Party necessary or advisable for the

                                      -8-

<PAGE>


                           purpose  of  collecting  or  enforcing  payment  or
                           performance of the Secured Obligations;

                  (iii)    to take  possession  of any or all of the  Collateral
                           and,  for that  purpose,  to enter,  with the aid and
                           assistance  of any  person  or  persons,  subject  to
                           proper  legal   process,   any  premises   where  the
                           Collateral,  or any  part  thereof,  is,  or may  be,
                           placed  or  assembled,  and to  remove  any  of  such
                           Collateral;

                  (iv)     to execute  any  instrument  and do all other  things
                           necessary  and proper to  protect  and  preserve  and
                           realize  upon the  Collateral  and the  other  rights
                           contemplated hereby; and

                  (v)      upon  notice to such  effect,  to  require  Debtor to
                           deliver,  at Debtor's expense,  any or all Collateral
                           to  Secured  Party at a place  designated  by Secured
                           Party.

                          (b) Secured Party may take legal  proceedings
                           for the  appointment of a  receiver or receivers  (to
which  Secured Party shall be entitled as a matter of right) to take  possession
of the Collateral pending the sale thereof pursuant either to the powers of sale
granted by this Agreement or to a judgment, order or decree made in any judicial
proceeding for the  foreclosure or involving the enforcement  of this Agreement.
If,  after the  exercise  of any or all of the rights and  remedies  of  Secured
Party  hereunder, any  of the  Secured  Obligations  shall remain unpaid, Debtor
shall  remain  liable for  any deficiency.  After  the  payment in full  of  the
Secured  Obligations, any proceeds of the Collateral received or held by Secured
Party  shall  be  delivered  to  Debtor, and the Collateral  shall be reassigned
to Debtor by Secured Party without  recourse to Secured Party (other

                                      -9-

than  for  their  gross  negligence  or  willful  misconduct)  and  without  any
representations, warranties or agreements of any kind.

                           (c)      If Debtor  fails to  perform  any  agreement
contained  herein, Secured  Party may  itself perform, or cause  performance of,
such agreement or obligation, and the expenses  of Secured  Party  incurred  in
connection  therewith  shall  be payable by Debtor pursuant to Section 8 hereof.

                           (d)      The  powers conferred  on  Secured  Party
hereunder are solely  to protect  its interest  in the Collateral and  shall not
impose any duty upon it to exercise any such powers. Except for the safe custody
of any  Collateral in  its possession  and the  accounting  for  moneys actually
received by it hereunder,  Secured Party shall have no duty as to any Collateral
or  as to the  taking of any  necessary steps to preserve  rights  against prior
Party or any other rights  pertaining to any Collateral.

                  7. Application of Moneys.  Except as otherwise may be provided
herein  or in the  Note,  all  moneys  which  Secured  Party  shall  receive  in
accordance  with the provisions  hereof shall be applied (to the extent thereof)
in the  following  manner:  First,  to the  payment  of all costs  and  expenses
incurred  in  connection  with the  administration  and  enforcement  of, or the
preservation  of any  rights  under,  this  Agreement  or any of the  reasonable
expenses and disbursements of Secured Party (including,  without limitation, the
reasonable fees and disbursements of its counsel and agents); and Second, to the
payment of all Secured  Obligations arising out of the Note or this Agreement in

actions or  proceedings  arising out of or related to the  Collateral,  shall be
borne and paid by Debtor on demand by Secured Party and until so paid,  shall be
added to the principal amount of the Secured Obligations and shall bear interest
at the rate then  prevailing  under the  terms of the Note with  respect  to the
outstanding principal thereof. In addition,  Debtor shall pay, and indemnify and
hold  Secured  Party  harmless  from  and  against,  any  and  all  liabilities,

any guaranty  securing the  Secured Obligations,  whether executed and delivered
heretofore or hereafter, or the payment by Debtor of any Secured Obligations nor

                     COVENANTS AS TO THE MORTGAGED PROPERTY

Mortgage and any  instruments  amending or  supplementing  this Mortgage and any

not yet due or being  contested  in good faith and by  appropriate  proceedings,
(ii) liens of carriers,  warehousemen,  mechanics and materialmen and other like
Encumbrances incurred in the ordinary course of business for sums not yet due or
being  contested  in good faith and by  appropriate  proceedings  ; (iii)  liens
incurred or deposits made in the ordinary  course of business in connection with
workers'  compensation and unemployment  insurance;  (iv) minor imperfections of
title which do not in the aggregate  materially detract from the value or use of
the asset in question,  (v) any and all  Encumbrances set forth on title reports
and/or lien searches,  (vi) easements,  rights of way, reservations,  servitudes
and other  restrictions  upon any assets of the Company that are  immaterial  in

the Agreement) on the Company or (B) materially  impair the Company's ability to
perform its obligations under this Agreement or the Agreement.


                  1.02 Liens.  Company will not directly or indirectly create or
permit or suffer to be created  or to remain,  and will  promptly  discharge  or
cause to be discharged, any mortgage, lien, encumbrance or charge on, pledge of,
security interest in or conditional sale or other title retention agreement with
respect to the Mortgaged Property or any part thereof or the interest of Company

request, as further security for the Loan secured hereby, Company's interests in
all  agreements,   contracts,  licenses  and  permits  affecting  the  Mortgaged

Lender;  but no such assignment shall be construed as a consent by Lender to any
agreement, contract, license or permit so assigned, or to impose upon Lender any
obligations with respect thereto.

                  1.04 Acquired  Property  Subject to Lien.  All property at any
time acquired by Company and required by this Mortgage to become  subject to the
lien and  security  interest  hereof,  whether  such  property  is  acquired  by
exchange, purchase, construction or otherwise, shall forthwith become subject to
the lien and security  interest of this Mortgage  without  further action on the
part of Company or Lender.  Company will execute and deliver to Lender (and will
record and file as provided in Section 1.01) an instrument  supplemental to this
Mortgage,  satisfactory  in  substance  and  form to  Lender,  whenever  such an
instrument is necessary under applicable law to subject to the lien and security
interest of this Mortgage all right, title and interest of Company in and to all
property  required  by this  Mortgage  to be  subject  to the lien and  security
interest  hereof and acquired by Company  since the date of this Mortgage or the

lien hereof, whichever is later.

                  1.05 No  Claims  Against  Lender.  Nothing  contained  in this
Mortgage shall constitute any consent or request by Lender,  express or implied,
for the  performance of any labor or services or the furnishing of any materials
or other property in respect of the Mortgaged  Property or any part thereof,  or
shall be construed to permit the making of any claim  against  Lender in respect
of labor or services or the furnishing of any materials or other property or any
claim that any lien based on the  performance  of such labor or  services or the
furnishing of any such  materials or other property is prior to the lien of this
Mortgage.

                  1.06  Indemnification   Against   Liabilities.   Company  will
protect, indemnify, save harmless and defend Lender from and against any and all
liabilities,   obligations,   claims,  damages,  penalties,  causes  of  action,
judgments,   costs  and  expenses  (including  reasonable  attorneys'  fees  and
expenses)  imposed upon or incurred by or asserted  against  Lender by reason of
(a) any accident,  injury to or death of persons or loss of or damage to or loss
of the use of property  occurring on or about the Mortgaged Property or any part
thereof or the adjoining  sidewalks,  curbs,  vaults and vault  spaces,  if any,
streets,  alleys or ways,  (b) any use,  non-use or condition  of the  Mortgaged
Property or any part thereof or the adjoining sidewalks, curbs, vaults and vault
spaces, if any, streets,  alleys or ways, (c) any failure on the part of Company
to perform or comply with any of the terms of this Mortgage,  (d) performance of
any labor or services or the  furnishing of any  materials or other  property in
respect of the  Mortgaged  Property or any part  thereof  made or suffered to be

part of Company or any of its agents, contractors, lessees, sublessee, licensees
or invitees, (f) any work in connection with any permitted alterations, changes,
new  construction  or  demolition  of or  additions  to the  Realty,  or (g) any
agreement  between Company and the Lender  originally named herein in connection
with the closing of the Loan  evidenced by the Note. If any action or proceeding
be commenced,  including an action to foreclose  this Mortgage or to collect the
Indebtedness  secured hereby, to which action or proceeding the Lender is made a
party by reason of this Mortgage or the Note,  or in which it becomes  necessary
to defend or  uphold  the lien of this  Mortgage,  all  reasonable  sums paid by
Lender for the expense of any  litigation  to prosecute or defend the rights and
lien created hereby, shall be paid by Company to Lender as hereinafter provided.
Company will pay and save Lender  harmless  against any and all  liability  with
respect to any  intangible  personal  property tax or similar  imposition of the
State in which the Mortgaged Property is located or any subdivision or authority
thereof now or hereafter  in effect,  to the extent that the same may be payable
by Lender in respect of this Mortgage or the Note. All

                                       4

<PAGE>


amounts  payable to Lender under this Section 1.06 shall be deemed  Indebtedness
secured by this  Mortgage and any such amounts that are not paid within ten (10)
days after written demand  therefor by Lender shall bear interest at the Default
Rate (as defined in the Note) from the date of such demand.  In case any action,
suit or proceeding is brought  against Lender by reason of any such  occurrence,
Company,  upon request of Lender, will, at Company's reasonable expense,  resist
and defend such action,  suit or  proceeding or cause the same to be resisted or
defended,  by counsel  designated by Company and reasonably  approved by Lender.
The  obligations  of Company under this Section 1.06 shall survive any discharge
of this Mortgage and payment in full of the Indebtedness.

                  1.07 Further Assurances. Company will execute, acknowledge and
deliver all such  instruments  and take all such  actions as Lender from time to
time may  request  (a) to  subject  to the lien and  security  interest  of this
Mortgage all or any portion of the Mortgaged Property,  (b) to perfect,  publish
notice  or  protect  the  validity  of the lien and  security  interest  of this
Mortgage, (c) to preserve and defend the title to the Mortgaged Property and the
rights of Lender  therein  against the claims of all persons and parties so long
as this  Mortgage  shall  remain  undischarged,  (d) to  subject to the lien and
security   interest  of  this  Mortgage  with  respect  to  any  replacement  or
substitution for any Improvements or any other after-acquired  property,  or (e)
in order to further effectuate the purpose of this Mortgage and to carry out the
terms  hereof and better to assure and confirm to Lender its rights,  powers and
remedies hereunder.


                                   ARTICLE II.

                       COVENANTS AS TO INSURANCE, DAMAGE,
                             DESTRUCTION AND TAKING


                  2.01 Insurance. Company shall, at its reasonable expense, keep
the Mortgaged Property insured for the benefit of the Lender (a) against loss by
fire and other hazards covered by an all-risk coverage  insurance policy for the
full insurable value thereof with reductions for  depreciation or  co-insurance,
with  deductible  from the loss payable for any  casualty and (b)  comprehensive
General  Liability  Insurance  in  respect  of the  operation  of the  Mortgaged
Property  with limits of  liability  for property  damage and bodily  injury per
occurrence.

                  2.02 Damage,  Destruction  or Taking;  Company to Give Notice;
Assignment  of  Awards.  In case  of (a) any  damage  to or  destruction  of the
Mortgaged Property or any part thereof, or (b) any taking (whether for permanent
or temporary  use) of all or any part of the Mortgaged  Property or any interest
therein  or  right  accruing  thereto,  as  the  result  of  or  in  lieu  or in
anticipation of the exercise of the right of condemnation or eminent domain,  or
a change of grade  affecting  the  Mortgaged  Property  or any part  thereof  (a
"Taking"),  or the  commencement of any proceedings or negotiations  which might
result in any such Taking,  Company will promptly give written notice thereof to
Lender, generally describing the nature and extent of such damage or destruction
or of such  Taking or the nature of such  proceedings  or  negotiations  and the
nature and extent of the Taking which might result therefrom, as the case

                                       5

<PAGE>


may be. Lender shall be entitled to all insurance proceeds payable on account of
such  damage or  destruction  and to all  awards or  payments  allocable  to the
Mortgaged  Property  on  account  of  such  Taking,  up to  the  amount  of  the
Indebtedness  (including  the accrued and unpaid  interest)  and Company  hereby
irrevocably assigns to Lender all rights of Company to any such proceeds,  award
or payment and irrevocably authorizes and empowers Lender, at its option, in the
name of Company,  or otherwise,  to file and prosecute  what would  otherwise be
Company's claim for any such proceeds,  award or payment and to collect, receipt
for and  retain the same for  disposition,  in  accordance  with  Section  2.03.
Company  will pay all  reasonable  costs  and  expenses  incurred  by  Lender in
connection  with any such  damage,  destruction  or Taking and the  seeking  and
obtaining of any insurance proceeds, award or payment in respect thereof.

                  2.03 Application of Proceeds. Lender may, at its option and in
its discretion,  apply all amounts recovered under any insurance policy required
to be  maintained  by Company  hereunder  and all net awards  received  by it on
account of any Taking in any one or more of the following  ways: (a) as provided
in Section 3.09,  regardless of whether part or all of the Indebtedness  secured
hereby  shall  then  be  matured  or  unmatured,  or (b) to  fulfill  any of the
covenants  contained herein as Lender may determine,  or (c) released to Company
for application to the cost of restoration and repair of the Mortgaged Property,
or (d) released to Company.



                                  ARTICLE III.

                                EVENTS OF DEFAULT

                  3.01 "Event of Default" means (i) an Event of Default, as such
term is defined in the Note,  or (ii) the breach or  violation by the Company of
any  representation,  covenant  or other  agreement  contained  herein or in the
Security Agreement.


                  3.02  Acceleration  of Maturity.  If an Event of Default shall
have  occurred  and  remain  uncured,  Lender  may  declare  the  entire  unpaid
Indebtedness  and all  other  sums  secured  hereby  to be  immediately  due and
payable.

                  3.03  Lender's  Power of  Enforcement.  If an Event of Default
shall have occurred and remain uncured, Lender may, either with or without entry
or taking possession as hereinabove provided or otherwise, and without regard to
whether or not the  Indebtedness  and other sums secured hereby shall be due and
without  prejudice to the right of the Lender  thereafter  to bring an action of
foreclosure  or any  other  action  for any  default  existing  at the time such
earlier action was commenced, bring any appropriate action or proceeding: (a) to
enforce  payment of the Note or the  Indebtedness or the performance of any term
thereof or hereof or any other  right of the Lender  under this  Mortgage or any
other  agreements  securing the Note and/or the  Indebtedness;  (b) to foreclose
this Mortgage and any other documents securing the Note and the Indebtedness and
to sell, as an entirety or in separate lots or parcels,  the Mortgaged  Property
under the power of sale  hereinafter  provided  or the  judgment  or decree of a
court or courts of

                                       6

<PAGE>


competent jurisdiction;  and (c) to pursue any other remedy available to it. The
Lender shall take action  either by such  proceedings  or by the exercise of its
power with respect to entry and/or  taking  possession,  or both,  as the Lender
may, in its reasonable discretion, determine.

                  3.04     Lender's Rights to Enter and
                           Take Possession, Operate and Apply Income.

                           (a)      If an Event of Default shall  have  occurred
(and remain uncured), (i) upon demand of the Lender, the Company shall forthwith
surrender to the Lender the  actual  possession  of the  Mortgaged  Property and
if and to the  extent permitted by law,  the Lender  itself, or by such officers
or agents as it may appoint,  may enter and take possession  of all or a portion
of the  Mortgaged Property  and may  exclude  the  Company  and its  agents  and
employees  wholly therefrom  and may have joint  access with the Company  to the
books, papers and accounts of the Company; and (ii) the Company will pay monthly
in advance to the Lender,  on Lender's entry into possession, or to any receiver
appointed to collect the rents, income  and  other  benefits  of  the  Mortgaged
Property, the fair and  reasonable  rental  value for the use and  occupation of
such part of the Mortgaged Property as may remain in  possession of the Company,
and upon default in any such payment  will vacate and  surrender  possession of
such part of the Mortgaged  Property to the Lender or to such receiver  and, in
default thereof, the Company may be evicted by summary proceedings or otherwise.

                           (b)      If the Company shall for any reason  fail to
surrender or  deliver  the  Mortgaged Property  or  any  part  thereof after the
Lender's demand, the Lender may obtain a judgment  or decree  conferring  on the
Lender the right to  immediate possession  or requiring the Company  to  deliver
immediate  possession of all or part of the Mortgaged  Property to  the  Lender.
The Company shall pay the Lender, upon demand, all reasonable costs and expenses
of obtaining  such judgment or decree and reasonable compensation to the Lender,
its  attorneys  and  agents, and all  such  reasonable  costs,  expenses  and
compensation  shall,  until paid, be secured by the lien of this Mortgage.

                           (c)      Upon  every such entering upon or taking of
possession, the Lender may hold,  store, use,  operate,  manage and control the
Mortgaged  Property and conduct the business thereof, and, from time to time:

                           (i)      make and conduct all necessary and proper
maintenance, repairs, renewals,  replacements,  additions,  betterments and
improvements  thereto and thereon and purchase or otherwise acquire fixtures,
personal and other property;

                           (ii)     insure  and keep  the  Mortgaged Property
 insured;

                           (iii) manage and operate the  Mortgaged  Property and
exercise all the rights and  powers of the Company in its name or otherwise with
respect to the same;

                           (iv) enter into  agreements  with  others to exercise
the powers herein  granted the Lender, all as the  Lender from  time to time may
determine; and the Lender may

                                       7

<PAGE>


collect and receive all the rents, income and other benefits thereof,  including
those  past due as well as those  thereafter;  and  shall  apply  the  monies so
received by the Lender to pay all  reasonable  costs and expenses of so entering
upon,  taking  possession  of,  holding,  operating,   maintaining,   repairing,
preserving,  and managing the Mortgaged  Property or any part  thereof,  and any
taxes,  assessments or other charges prior to the lien and security  interest of
this Mortgage  which Lender may consider  necessary or desirable to pay, and any
balance of such amount shall be applied as provided in Section 3.09.

          The Lender shall surrender possession of the Mortgaged Property to the
Company at such time that all amounts due under any of the terms of the Note and
this Mortgage shall have been fully paid and all Events of Defaults  cured.  The
same right of taking possession, however, shall exist if any subsequent Event of
Default shall occur and be continuing.

                  3.05 Purchase by Lender;  Application of  Indebtedness  Toward
Purchase  Price.  Lender may be a purchaser of the Mortgaged  Property or of any
part thereof or of any interest therein at any sale thereof, whether pursuant to
foreclosure  or otherwise,  and may apply toward the purchase  price thereof the
Indebtedness  secured  hereby  owing  to  Lender.  Lender  shall,  upon any such
purchase, acquire good title to the properties so purchased, free of the lien of
this Mortgage and free of all rights of redemption in Company.

                  3.06 Waiver of Appraisement,  Valuation,  Stay,  Execution and
Redemption  Laws. The Company agrees to the full extent permitted by law that in
case of an Event of Default on its part  hereunder  which  shall be  continuing,
neither the Company  nor anyone  claiming  through or under it shall or will set
up,  claim  or seek to take  advantage  of any  appraisement,  valuation,  stay,
extension or redemption  laws now or hereafter in force,  in order to prevent or
hinder the  enforcement  or foreclosure of this Mortgage or the absolute sale of
the  Mortgaged  Property  or the  final and  absolute  putting  into  possession
thereof, immediately after such sale, of the purchasers thereat, and the Company
for itself and all who may at any time claim through or under it, hereby waives,
to the full extent  that may be lawfully so done,  the benefit of all such laws,
and any and all  right to have the  assets  comprising  the  Mortgaged  Property
marshaled upon any  foreclosure of the lien hereof and agrees that the Lender or
any court  having  jurisdiction  to foreclose  such lien may sell the  Mortgaged
Property  in part or as an  entirety.  Company  agrees that it will not assert a
defense in any action to recover a deficiency  judgment  following a foreclosure
that the sales price realized at the sale was less than the fair market value.

                  3.07     Sale a Bar; Note Due on Sale.

                           (a)     Any  sale of  the Mortgaged  Property  or any
part  thereof  or  any  interest therein under  or  by  virtue of this Mortgage,
whether  pursuant  to foreclosure or otherwise, shall forever be a  bar  against
Company.

                           (b)      Upon any sale by Lender  under or  by virtue
of this Mortgage, whether pursuant to foreclosure or power of sale or otherwise,
the entire unpaid principal  amount of the Note at the time  outstanding  shall,
if not previously declared due and payable, immediately

                                       8

<PAGE>




become due and payable,  together  with interest  accrued  thereon and all other
Indebtedness which this Mortgage by its terms secures.

                  3.08 Lender Authorized to Execute Deeds.  Company  irrevocably
appoints  Lender its true and lawful  attorney in fact coupled with an interest,
in its name and stead and on its  behalf,  for the purpose of  effectuating  any
sale, assignment,  transfer or delivery for the enforcement hereof,  pursuant to
foreclosure or otherwise,  to execute and deliver all such deeds,  Leases, bills
of sale, assignments, releases and other instruments as may be necessary.

                  3.09  Application  of Proceeds of Sale and Other  Moneys.  The
proceeds  of any  sale of the  Mortgaged  Property  or any part  thereof  or any
interest  therein  under or by  virtue of this  Mortgage,  whether  pursuant  to
foreclosure  or  otherwise,  and all other  moneys at any time held by Lender as
part of the Mortgaged Property, shall be applied as follows:

          First:  to the payment of the  reasonable  costs and  expenses of such
sale (including,  without limitation,  reasonable  attorneys' fees and expenses,
the cost of  evidence  of title and the costs and  expenses,  if any,  of taking
possession  of,  retaining  custody  over,   repairing,   managing,   operating,
maintaining  and preserving the Mortgaged  Property or any part thereof prior to
such sale and the costs,  taxes, fees and expenses of transferring the Mortgaged
Property  pursuant  to such  sale),  all  reasonable  costs and  expenses of any
receiver  of the  Mortgaged  Property  or  any  part  thereof,  and  any  taxes,
assessments  or charges  prior to the lien of this  Mortgage,  which  Lender may
consider  necessary  or  desirable  to pay (in no event  shall  the  Company  be
entitled to receive any payment for any services rendered in connection with any
such sale);

          Second: to the payment of any  Indebtedness secured by  this Mortgage,
other than indebtedness with respect to the Note at the  time outstanding, which
Lender may consider necessary or desirable to pay in its discretion;

          Third: to the payment of all amounts of principal of, premium, if any,
and  interest  at the time due and  payable on the Note at the time  outstanding
(whether due by reason of maturity or as an installment of interest or by reason
of any prepayment  requirement or by declaration of  acceleration or otherwise),
including interest at the Default Rate on any overdue principal and premium,  if
any, and (to the extent permitted under applicable law) on any overdue interest;
and in case such moneys shall be  insufficient to pay in full the amounts so due
and unpaid upon the Note at the time outstanding, then, first, to the payment of
all amounts of  interest at the time due and payable on the Note,  and second to
the payment of all amounts of principal at the time due and payable on the Note;
and

          Fourth:  the balance,  if any, held by Lender after payment in full of
all amounts referred to in subdivisions  First,  Second and Third above,  shall,
unless a court of competent jurisdiction may otherwise direct by final order not
subject to appeal, be paid to or upon the direction of Company.

                  3.10  Appointment  of Receiver.  If an Event of Default  shall
have occurred and be continuing,  the Lender, to the extent permitted by law and
without  regard to the value,  adequacy or  sufficiency  of the security for the
Indebtedness and other sums secured hereby, shall

                                       9

<PAGE>


be  entitled  as a matter of right,  if it so elects,  to the  appointment  of a
receiver to enter upon and take  possession  of the  Mortgaged  Property  and to
collect all rents,  income and other benefits  thereof and apply the same as the
court may direct. The reasonable expenses, including receiver's fees, reasonable
attorneys' fees, costs and reasonable agent's compensation, incurred pursuant to
the powers  herein  contained  shall be secured by this  Mortgage.  The right to
enter and take  possession of and to manage and operate the  Mortgaged  Property
and to  collect  all  rents,  income and other  benefits  thereof,  whether by a
receiver  or  otherwise,  shall be  cumulative  to any  other  right  or  remedy
hereunder  (or afforded by law or in equity) and may be  exercised  concurrently
therewith or independently  therewith or independently thereof. The Lender shall
be liable to account  only for such rents,  income and other  benefits  actually
received by the Lender,  whether  received  pursuant to this  Section or Section
3.04.

                  3.11  Right of  Lender  to  Perform  Company's  Covenants.  If
Company shall fail to make any payment or perform any act required to be made or
performed  hereunder,  Lender,  without  notice to or demand upon  Company,  and
without waiving or releasing any obligation or default,  may (but shall be under
no  obligation  to) make such payment or perform such act for the account and at
the reasonable expense of Company. No such action shall be deemed an eviction of
any tenant of the Mortgaged Property or any part thereof. All sums so reasonably
paid by  Lender  and all  reasonable  costs  and  expenses  (including,  without
limitation,  attorneys' fees and reasonable expenses) so incurred, together with
interest  thereon at the  Default  Rate from the date of  payment or  incurring,
shall constitute  additional  Indebtedness secured by this Mortgage and shall be
paid by Company to Lender on demand.

                  3.12 Suits to Protect the Mortgaged Property. The Lender shall
have the power and authority to institute and maintain any suits and proceedings
as the Lender may deem advisable in its  reasonable  judgment (a) to prevent any
impairment  of the  Mortgaged  Property by any acts which may be unlawful or any
violation  of this  Mortgage,  (b) to preserve  or protect  its  interest in the
Mortgaged  Property,  and (c) to restrain the  enforcement of or compliance with
any  legislation  or other  governmental  enactment,  rule or order  which might
reasonably be expected to impair the security hereunder or be prejudicial to the
Lender's interest.

                  3.13     Company to Pay the Note on Any Default in Payment.

                           (a)      If default shall be made in the payment of
any amount due under the Note, this Mortgage or any other instrument  securing
the Note or evidencing the Indebtedness,  then, the Lender shall be entitled to
seek a judgment against the Company for the whole amount so due and unpaid,
together with reasonable  costs and  expenses,  including,  without  limitation,
the  reasonable compensation, expenses and disbursements of the Lender's agents,
attorneys   and  other  representatives,  either  before, after  or  during  the
pendency of any proceedings for the enforcement of this  Mortgage; and the right
of the Lender to  recover such judgment  shall not  be affected by any taking of
possession  or  foreclosure sale  hereunder,  or by the exercise  of  any  other
right,  power or remedy for the  enforcement  of the  terms  of this  Mortgage,
or the foreclosure  of the lien hereof.

                           (b)      In case of a foreclosure sale of all or any
part of the Mortgaged Property  and of the  application  of the proceeds of sale
to the payment of  the sums  secured  hereby,  the Lender shall be  entitled  to
enforce  payment from the Company of all amounts  then remaining  due and unpaid
and to recover  judgment against the Company for  any portion thereof  remaining
unpaid,  with interest at the Default Rate.

                           (c)      The Company  hereby  agrees, to  the  extent
permitted  by law, that no  recovery of any  such  judgment by the Lender and no
attachment or levy of any execution  upon  any of the Mortgaged  Property or any
other  property  shall  in any way  affect  the lien of this  Mortgage  upon the
Mortgaged  Property  or  any  part  thereof  or  of any lien, rights, powers or
remedies of the Lender hereunder,  but such lien, rights, powers  and  remedies
shall continue unimpaired as before.

                           (d)      Any monies  collected  or  received  by  the
Lender under this Section 3.13 shall be applied as provided in Section 3.09.

                           (e)      The provisions of  this Section shall not be
deemed  to  limit  or  otherwise modify  the  provisions of any guaranty of the
Indebtedness evidenced by the Note or secured by this Mortgage.

                  3.14 Delay or  Omission  No Waiver.  No delay or  omission  of
Lender  or of any  holder of the Note to  exercise  any  right,  power or remedy
accruing upon any Event of Default shall exhaust or impair any such right, power
or  remedy  or shall be  construed  to waive  any such  Event of  Default  or to
constitute  acquiescence  therein.  Every  right,  power and remedy given to the
Lender  may be  exercised  from  time  to time  and as  often  as may be  deemed
expedient by the Lender.

                  3.15 No Waiver of One Default to Affect Another.  No waiver of
any Event of Default  hereunder  shall extend to or affect any subsequent or any
other Event of Default then existing,  or impair any rights,  powers or remedies
consequent thereon. If the Lender (a) grants forbearance or an extension of time
for the  payment  of any sums  secured  hereby;  (b) takes  other or  additional
security  for the payment of the  Indebtedness;  (c) waives or does not exercise
any right granted in the Note, this Mortgage or any instrument securing the Note
or evidencing the Indebtedness;  (d) releases any part of the Mortgaged Property
from the lien of this  Mortgage  or any other  instrument  securing  the Note or
evidencing  the  Indebtedness;  (e)  consents to the filing of any map,  plat or
replat of the  Realty;  (f)  consents  to the  granting  of any  easement on the
Realty;  or (g) makes or consents to any  agreement  changing  the terms of this
Mortgage  or  subordinating  the lien or any  charge  hereof,  then,  except  as
otherwise  provided by an  instrument  executed  by the  Lender,  no such act or
omission  shall  release,  discharge,  modify,  change  or affect  the  original
liability  under the Note,  this  Mortgage  or  otherwise  of the Company or any
subsequent  purchaser  of the  Mortgaged  Property  or any part  thereof  or any
Guarantor. No such act or omission shall preclude the Lender from exercising any
right,  power or privilege  herein  granted or intended to be granted in case of
any Event of Default then  existing or of any  subsequent  Event of Default nor,
except as otherwise  expressly provided in an instrument executed by the Lender,
shall the lien of this Mortgage be altered thereby, except to the extent of

                                       11

releases as described in clause (d) of the second sentence of this Section 3.15.
In the event of the sale or transfer by  operation of law or otherwise of all or
any part of the Mortgaged  Property,  the Lender,  without notice to any person,
firm or  corporation,  is hereby  authorized and empowered to deal with any such
vendee  or  transferee   with  reference  to  the  Mortgaged   Property  or  the
Indebtedness secured hereby, or with reference to any of the terms or conditions
hereof,  as fully  and to the same  extent as it might  deal  with the  original
parties  hereto  and  without in any way  releasing  or  discharging  any of the
liabilities or undertakings hereunder.

                  3.16  Compromise  of Actions.  Any action,  suit or proceeding
brought by Lender  pursuant to any of the terms of this  Mortgage or  otherwise,
and  any  claim  made by  Lender  hereunder  may be  compromised,  withdrawn  or
otherwise  dealt with by Lender  without  any notice to or  approval of Company,
except as shall be required by law and may not be waived.

                  3.17  Discontinuance  of  Proceedings;   Position  of  Parties
Restored.  If the Lender  shall have  proceeded  to enforce  any right or remedy
under this  Mortgage by  foreclosure,  entry or otherwise  and such  proceedings
shall have resulted in a final determination adverse to the Lender, then, and in
every such case,  the Company and the Lender  shall be restored to their  former
positions  and rights  hereunder,  and all  rights,  powers and  remedies of the
Lender shall continue as if no such proceedings had occurred or had been taken.

                  3.18  Remedies  Cumulative.  Each  right,  power and remedy of
Lender  provided for in this Mortgage or now or hereafter  existing at law or in
equity or by statute or otherwise  shall be cumulative  and concurrent and shall
be in  addition  to every  other  right,  power or remedy  provided  for in this
Mortgage  or now or  hereafter  existing  at law or in equity or by  statute  or
otherwise, and the exercise or beginning of the exercise by Lender of any one or
more of the rights,  powers or remedies  provided for in this Mortgage or now or
hereafter  existing  at law or in equity or by  statute or  otherwise  shall not
preclude the  simultaneous  or later exercise by Lender of any or all such other
rights,  powers or remedies.  If the  Mortgaged  Property is located  within the
State of New York,  the Lender  shall have,  in addition to any other  rights it
might  have,  all the rights  granted to Lenders  pursuant to Section 254 of the
Real Property Law.

                  3.19  Right of  Set-Off.  Upon the  occurrence  and during the
continuance  of any Event of Default,  the Lender or any  affiliate of Lender is
hereby  authorized  at any time and from  time to time,  without  notice  to the
Company (any such notice being expressly waived by the Company),  to set off and
apply any and all deposits (general or special, time or demand) at any time held
and other  indebtedness  at any time owing by the Lender to or for the credit or
the account of the Company against any and all of the obligations of the Company
now or hereafter  existing under this Mortgage,  the Note or any other agreement
between the Company and/or any of the  individuals  collectively  referred to as
the Company and although such  obligations  may be unmatured.  The rights of the
Lender  under this  subsection  are in addition to all other rights and remedies
(including,  without  limitation,  other rights of set-off) which the Lender may
have.  The  parties  specifically  agree  that any  set-off  shall not impede or
interfere  with  Lender's  right to continue any legal action or  proceeding  to
enforce  the Note and this  Mortgage,  including  an  action to  foreclose  this
Mortgage.

                  3.20 Interest  After Event of Default.  If an Event of Default
shall have occurred and be continuing, all sums outstanding and unpaid under the
Note and this  Mortgage  shall,  at the Lender's  option,  bear  interest at the
Default Rate.

                  3.21 Provisions Subject To Applicable Law. All rights,  powers
and remedies  provided in this Mortgage may be exercised only to the extent that
the exercise  thereof does not violate any applicable  provisions of law and are
intended to be limited to the extent necessary so that they will not render this
Mortgage  invalid,  unenforceable or not entitled to be recorded,  registered or
filed under the provisions of any  applicable  law. If any term of this Mortgage
or any application  thereof shall be invalid or unenforceable,  the remainder of
this  Mortgage  and any other  application  of such term  shall not be  affected
thereby.

                  3.22 Prepayment After Default.  If following the occurrence of
any Event of Default  under this  Mortgage  and an exercise by the Lender of its
option to declare the whole of the  Indebtedness  due and  payable,  the Company
shall tender payment of an amount sufficient to satisfy the entire  Indebtedness
secured  hereby  at any  time  prior  to a  foreclosure  sale  of the  Mortgaged
Property,  and if at the time of such tender prepayment of the principal balance
of the Note is  prohibited,  the Company  shall,  in addition to the said entire
principal,  also pay to the Lender a sum equal to the interest  which would have
accrued on the  principal  balance of the Note at the Default Rate from the date
of such tender to the end of the period during which prepaying is prohibited. If
at the time of such tender,  prepayment of the Note is permitted, such tender by
Company  shall be  deemed to be a  voluntary  prepayment  of the said  principal
balance of the Note,  and the  Company  shall,  in  addition  to the said entire
principal,  also pay to the Lender the applicable  prepayment  premium,  if any,
specified in the Note. All such payments shall also be accompanied by payment of
all accrued interest under the Note.

                  3.23 Defeasance.  If Company shall pay or cause to be paid the
principal of and premium,  if any, and interest on the Note, in accordance  with
the  terms  thereof,  and if the  Company  shall  pay or  cause  to be paid  all
Indebtedness  and other sums  payable or secured  hereunder  by the  Company and
shall  comply with all terms,  conditions  and  requirements  hereof,  then this
Mortgage  shall be null and void and of no further force and effect and shall be
released by the Lender upon the written request and at the reasonable expense of
the Company.

                               SECURITY AGREEMENT

                  4.01  Security   Agreement.   The  Company  expressly  agrees,
intending that the Lender rely thereon, that this Mortgage also shall constitute
a "security  agreement",  as such term is defined in the Uniform Commercial Code
in the jurisdiction wherein the Mortgaged Property is situated (the "Code"). The
Mortgaged  Property  includes,  and shall be deemed to include,  inter alia, the
Improvements,  the Realty and all fixtures and other  property  described in the
Granting

                                       13

<PAGE>




Clause of the Mortgage,  (hereinafter  collectively referred to as the "Chattels
and Intangibles")  regardless of whether they are held or hereafter acquired, of
the Company in, to, under and above the  Mortgaged  Property.  By executing  and
delivering this Mortgage,  the Company has granted,  in the same manner and with
the same effect  described  in the Granting  Clause  hereof,  to the Lender,  as
additional  security,  a security interest in the Chattels and Intangibles which
are subject to the Code. If any Event of Default  shall occur,  the Lender shall
have,  in addition to any and all other  rights and  remedies  set forth in this
Mortgage,  and may  exercise  without  demand,  any and all rights and  remedies
granted to a secured  party under the Code,  including,  but not limited to, the
right  to take  possession  of the  Chattels  and the  Intangibles,  or any part
thereof,  and the right to advertise and sell the Chattels and the  Intangibles,
or any part  thereof,  pursuant  to and in  accordance  with  the  power of sale
provided for in this Mortgage and Section 3.09 hereof.  The Company  agrees that
any notice of sale or other  action  intended by the Lender with  respect to the
Chattels and the Intangibles,  or any part thereof,  shall constitute reasonable
notice if it is sent to the  Company  not less  than ten (10) days  prior to any
such sale or intended action.

                  4.02 Financing  Statements.  The Company shall execute any and
all  such  documents  (including,  without  limitation,   Financing  Statements)
pursuant to the Code,  as the Lender may  request,  to preserve and maintain the
priority of the lien and security  interest created hereby on property which may
be deemed personal property or fixtures, and the Company shall pay to the Lender
on demand any reasonable  expenses incurred by the Lender in connection with the
preparation,  execution  and filing of any such  documents.  The Company  hereby
authorizes  and  empowers  the Lender to execute and file,  on its  behalf,  all
Financing Statements and refilings and continuations thereof as the Lender deems
necessary or  advisable  to create,  preserve and protect said lien and security
interest.  When and if the Company and the Lender shall respectively  become the
Debtor and Secured  Party in any Uniform  Commercial  Code  Financing  Statement
affecting the Mortgaged  Property or any part  thereof,  this Mortgage  shall be
deemed a security  agreement  as defined  in the Code and the  remedies  for any
violation  of the  covenants,  terms and  conditions  of the  agreements  herein
contained shall be (i) as prescribed herein, (ii) by general law, or (iii) as to
such part of the security which is also reflected in said Financing Statement by
the specific  statutory  consequences now or hereafter  enacted and specified in
the Code, all at the Lender's sole election.

                  4.03 No Impairment. The Company, and the Lender agree that the
filing  of a  Financing  Statement  in the  records  normally  having to do with
personal  property  shall never be  construed as in any way  derogating  from or
impairing  the express  declaration  and intention of the parties  hereto,  that
everything  used in connection  with the production of income from the Mortgaged
Property  and/or  adapted for use therein and/or which is described or reflected
in this  Mortgage is, and at all times and for all purposes and all  proceedings
both legal or equitable, shall be regarded as part of the real estate encumbered
by this  Mortgage  irrespective  of whether (i) any such  property is physically
attached  to  the  Realty,   (ii)  serial   numbers  are  used  for  the  better
identification  of certain equipment items capable of being thus identified in a
recital contained herein or in any list filed with the Lender, or (iii) any such
item is referred to or reflected in any such Financing Statement so filed at any
time. Similarly, the mention in any such Financing Statement of (1) rights in or
to the  proceeds  of any  fire  and/or  hazard  insurance  policy  or any  other
insurance policy, or (2) any award in eminent domain proceedings for a Taking or
for loss

                                       14

of value, or (3) the Company's interest as lessor in any present or future lease
or rights to income  growing  out of the use and/or  occupancy  of the  property
mortgaged  hereby,  whether  pursuant  to lease  or  otherwise,  shall  never be
construed as in any way  altering any of the rights of the Lender as  determined
by this instrument or impugning the priority of the Lender's lien granted hereby
or by any other recorded document,  but such mention in the Financing  Statement
is  declared  to be for the  protection  of the Lender in the event any court or
judge  shall at any time hold with  respect to clauses  (1) , (2) and (3) hereof
that notice of the  Lender's  priority of  interest  to be  effective  against a
particular  class of persons  (including,  but not  limited to, a trustee or the
federal  government and any  subdivisions  or entity of the federal  government)
must be filed in the Code records.



                                   ARTICLE V.

                            MISCELLANEOUS PROVISIONS

                  5.01  Construction of Lender's  Rights.  All covenants  hereof
shall be  construed  as affording  to the Lender  rights  additional  to and not
exclusive of the rights conferred under the provisions of Section 254 and 273 of
the Real Property Law of the State of New York.

                  5.02  Limitation on Interest.  Nothing in this  Mortgage,  the
Note or in any other agreement  between the Company and the Lender shall require
the Company to pay, or the Lender to accept,  interest in an amount  which would
subject the Lender to any penalty or  forfeiture  under  applicable  law. In the
event that the payment of any charges, fees or other sums due hereunder or under
the Note or any such  other  agreement,  which are or could be held to be in the
nature of  interest  and which  would  subject  the  Lender  to any  penalty  or
forfeiture  under  applicable  law,  then,  ipso facto,  the  obligations of the
Company to make such  payment  shall be reduced to the highest  rate  authorized
under applicable law. Should the Lender receive any payment which is or would be
in excess of the highest rate  authorized  under law,  such  payment  shall have
been, and shall be deemed to have been, made in error,  and shall  automatically
be applied to reduce the outstanding principal balance of the Indebtedness.

                  5.03 Successors in Interest;  Definitions.  All of the grants,
terms, conditions,  provisions and covenants of this Mortgage shall run with the
land,  shall be binding  upon the  Company and shall inure to the benefit of the
Lender,  subsequent holders of this Mortgage and their respective successors and
assigns. For the purpose of this Mortgage,  the term "Company" shall include and
refer to the  Company  named  herein,  any  subsequent  owner  of the  Mortgaged
Property,  or any part thereof,  and their respective  heirs,  executors,  legal
representatives,  successors and assigns. If there is more than one Company, all
their  undertakings  hereunder  shall be deemed joint and several.  Whenever the
context may require,  any pronouns used herein shall  include the  corresponding
masculine, feminine or neuter forms, and the singular form of nouns and pronouns
shall include the plural and vice versa.

                  5.04  Jurisdiction.  This  Agreement  shall  be  governed  and
controlled as to validity, enforcement, interpretation, construction, effect and
in all other  respects by the internal laws of the State of New York  applicable
to contracts made in that State.

                  5.05  Receipt of Copy of Mortgage;  Counterparts.  The Company
acknowledges  that it has received a true copy of this  Mortgage.  This Mortgage
may be executed  in any number of  counterparts,  and each of such  counterparts
shall for all  purposes be deemed to be an original;  and all such  counterparts
shall together constitute but one and the same mortgage.

documents  executed and delivered in connection  herewith or therewith  shall be

parties as  expressed  herein and therein and without  regard to any rule of law
requiring construction against the party who prepares such instruments.

all  payments  pursuant to Section 2.4 of the  Agreement  and/or  enforcing  any
rights  with  respect  to, or  collecting  against,  the  Guarantor  under  this
Guaranty.

                  (b)  Additionally,  the Guarantor hereby  unconditionally  and
irrevocably  guarantees  to the  Agent,  the  Individuals  and their  respective
successors,  indorsees,  transferees  and  assigns  on demand (i) the prompt and

reimbursement by the Parent,  Acquisition Corp. and Surviving Corporation of the
Individuals  as required by such Section  4.4.1 and(ii) the  obligations  of the
Obligors pursuant to Section 4.4.3 of the Agreement.

         3.  The  liability  of  the   Guarantor   hereunder  is  exclusive  and
independent  of any security for or other  guaranty of the  Obligations  whether
executed by the Guarantor,  any other  guarantor or by any other party,  and the
liability of the  Guarantor  hereunder  shall not be affected or impaired by (a)
any direction as to application of payment by any Obligor or by any other party,
(b) any other continuing or other guaranty,  undertaking or maximum liability of
a guarantor or of

                                      -3-

<PAGE>



any other party as to the Obligations, (c) any payment on or in reduction of any
such  other  guaranty  or  undertaking,  (d)  any  dissolution,  termination  or
increase, decrease or change in personnel by any Obligor or (e) any payment made
to the Agent or any Beneficiary on the Obligations  which any such Person repays
to any  Obligor  pursuant  to  court  order in any  bankruptcy,  reorganization,
arrangement,  moratorium  or other debtor relief  proceeding,  and the Guarantor
waives any right to the deferral or modification of its obligations hereunder by
reason  of any  such  proceeding.  This  is a  guaranty  of  payment  and not of
collection.

         4. The  obligations of the Guarantor  hereunder are  independent of the
obligations of any other  guarantor of any of the  Obligations,  or the Obligors
and a separate  action or actions  may be brought  and  prosecuted  against  the
Guarantor whether or not action is brought against any other guarantor of any of
the  Obligations or any Obligor and whether or not any other guarantor of any of
the  Obligations  or any Obligor be joined in any such  action or  actions.  The
Guarantor  waives,  to the fullest  extent  permitted by law, the benefit of any
statute of  limitations  affecting  its liability  hereunder or the  enforcement
thereof. Any payment by the Obligor or other circumstance which operates to toll
any statute of  limitations as to the Obligors shall operate to toll the statute
of limitations as to the Guarantor.

         5. The  Guarantor  hereby  waives (to the fullest  extent  permitted by
applicable  law)  notice  of  acceptance  of this  Guaranty  and  notice  of any
liability  which  may apply  (including  notice of the  existence,  creation  or
incurrence of new or additional indebtedness), and waives promptness, diligence,
presentment, demand of payment, protest, notice of dishonor or nonpayment of any
such liabilities, suit or taking of other action by the Agent or any Beneficiary
against,  and any other  notice  to, any party  liable  thereon  (including  the
Guarantor or any other guarantor of any of the Obligations).

         6. The Agent or any  Beneficiary  may  (except as shall be  required by
applicable  statute  and  cannot  be  waived)  at any time and from time to time
without  the  consent  of,  or  notice  to,  the  Guarantor,  without  incurring
responsibility to the Guarantor,  without impairing or releasing the obligations
of the  Guarantor  hereunder,  upon any terms or  conditions  and in whole or in
part:

                  (a)      exercise  or refrain  from  exercising  any  rights
against any Obligor or otherwise act or refrain from acting;

                  (b) settle or compromise any of the Obligations,  any security
therefor or any liability  (including any of those hereunder)  incurred directly
or indirectly in respect  thereof or hereof,  and may subordinate the payment of
all or any part thereof to the payment of any liability  (whether due or not) of
any Obligor to creditors of such Obligor;


                                      -4-

<PAGE>


                  (c) apply any sums by whomsoever paid or howsoever realized to
any  liability or  liabilities  of the Obligors to the Agent or any  Beneficiary
regardless of what liabilities of the Obligors remain unpaid;

                  (d) consent to or waive any breach of, or any act, omission or
default  under,  the  Agreement,   any  Transaction  Agreement  or  any  of  the
instruments or agreements  referred to therein,  or otherwise  amend,  modify or
supplement  the  Agreement,  any  Transaction  Agreement  or any of  such  other
instruments or agreements; and/or

                  (e)  act or  fail  to act in any  manner  referred  to in this
Guaranty which may deprive the Guarantor of its right to subrogation against any
Obligor to  recover  full  indemnity  for any  payments  made  pursuant  to this
Guaranty.

         7. No invalidity,  irregularity or  unenforceability of all or any part
of the  Obligations  or of any security  therefor  shall affect,  impair or be a
defense  to this  Guaranty,  and  (except  to the  extent,  if any,  as shall be
required by  applicable  statute and cannot be waived)  this  Guaranty  shall be
primary, absolute and unconditional  notwithstanding the occurrence of any event
or the existence of any other  circumstances  which might  constitute a legal or
equitable  discharge  of a surety or  guarantor,  except  payment in full of the
Obligations. No provision of this Guaranty shall be deemed to be a waiver by the
Guarantor of its right to assert that the Obligations have been paid in full.

         8. This Guaranty is a continuing  one and all  liabilities  to which it
applies or may apply under the terms  hereof shall be  conclusively  presumed to
have been  created in  reliance  hereon.  No failure or delay on the part of the
Agent or any Beneficiary in exercising any right,  power or privilege  hereunder
shall operate as a waiver thereof;  nor shall any single or partial  exercise of
any right,  power or privilege  hereunder preclude any other or further exercise
thereof or the exercise of any other right,  power or privilege.  The rights and
remedies  herein  expressly  specified are  cumulative  and not exclusive of any
rights or remedies which the Agent and the  Beneficiaries  would otherwise have.
No notice to or demand on the  Guarantor in any case shall entitle the Guarantor
to any other  further  notice or demand in  similar  or other  circumstances  or
constitute a waiver of the rights of the Agent or any  Beneficiary  to any other
or further  action in any  circumstances  without  notice or  demand.  It is not
necessary  for the Agent or any  Beneficiary  to inquire  into the  capacity  or
powers of any Obligor or the officers,  directors,  partners or companies acting
or  purporting  to act on its behalf,  and any  indebtedness  made or created in
reliance  upon  the  professed  exercise  of such  powers  shall  be  guaranteed
hereunder.

         9.  Any  indebtedness  of any  Obligor  now or  hereafter  held  by the
Guarantor  is hereby  subordinated  to the  indebtedness  of such Obligor to the
Agent  and the  Beneficiaries;  and such  indebtedness  of such  Obligor  to the
Guarantor,  if the  Agent,  after  an  Event  of  Default  has  occurred  and is
continuing,  so  requests,  shall be  collected,  enforced  and  received by the
Guarantor as trustee for the Agent and the Beneficiaries and be paid over to the
Agent, for the

                                      -5-

<PAGE>




benefit of the Beneficiaries,  on account of the indebtedness of such Obligor to
the Agent and the  Beneficiaries,  but without  affecting  or  impairing  in any
manner  the  liability  of the  Guarantor  under  the other  provisions  of this
Guaranty.  Prior to the  transfer  by the  Guarantor  of any note or  negotiable
instrument  evidencing any  indebtedness  of any Obligor to the  Guarantor,  the
Guarantor  shall mark such note or negotiable  instrument with a legend that the
same is subject to this  subordination.  Without  limiting the generality of the
foregoing, the Guarantor hereby agrees with the Agent and the Beneficiaries that
he will not exercise any right of subrogation which he may at any time otherwise
have as a result of this Guaranty (whether contractual, under Section 509 of the
Bankruptcy Code or otherwise)  until all Obligations  have been irrevocably paid
in full in cash.

         10. (a) The Guarantor  waives any right (except as shall be required by
applicable  statute or law and  cannot be  waived) to require  the Agent and the
Beneficiaries to: (i) proceed against any Obligor, any other guarantor of any of
the Obligations or any other party; (ii) proceed against or exhaust any security
held from any  Obligor,  any other  guarantor of any of the  Obligations  or any
other  party;  or  (iii)  pursue  any  other  remedy  in  the  Company's  or any
Beneficiary's  power  whatsoever.  The Guarantor  waives (to the fullest  extent
permitted by applicable  law) any defense based on or arising out of any defense
of the  Obligors,  any other  guarantor of any of the  Obligations  or any other
party  other  than  payment  in  full  of the  Obligations,  including,  without
limitation,  any  defense  based  on or  arising  out of the  disability  of any
Obligor,  any other  guarantor of any of the  Obligations or any other party, or
the  unenforceability  of the Obligations or any part thereof from any cause, or
the cessation  from any cause of the liability of any Obligor other than payment
in full of the  Obligations.  The  Agent  and the  Beneficiaries  may,  at their
election,  foreclose on any security held by the Agent or any Beneficiary by one
or more judicial or nonjudicial sales, or exercise any other right or remedy the
Agent or any  Beneficiary  may have against the Obligors or any other party,  or
any  security,  without  affecting or impairing in any way the  liability of the
Guarantor hereunder except to the extent the Obligations have been paid in full.
The Guarantor  waives any defense  arising out of any such election by the Agent
and  the  Beneficiaries,  even  though  such  election  operates  to  impair  or
extinguish any right of reimbursement or subrogation or other right or remedy of
the Guarantor against the Obligors or any other party or any security.

                  (b) The  Guarantor  assumes all  responsibility  for being and
keeping himself informed of each Obligor's  financial  condition and assets, and
of  all  other  circumstances  bearing  upon  the  risk  of  nonpayment  of  the
Obligations  and the nature,  scope and extent of the risks which the  Guarantor
assumes and incurs  hereunder,  and agrees that the Agent and the  Beneficiaries
shall  have no  duty to  advise  the  Guarantor  of  information  known  to them
regarding such circumstances or risks.

         11. The Agent and the  Beneficiaries  agree that no  Beneficiary  shall
have any right  individually to seek to enforce or to enforce this Guaranty,  it
being understood and agreed that

                                      -6-

such  rights  may be  exercised  solely  by the  Agent  for the  benefit  of the
Beneficiaries upon the terms of this Guaranty.

         12. In order to induce the  Company to enter  into and  consummate  the
transactions  contemplated by the Agreement, the Guarantor represents,  warrants
and covenants that:

                  (a) the  Guarantor  (i) is not in violation of any  applicable
law,  statute,  rule,  regulation  or  ordinance  in  any  respect  which  could
reasonably  be expected to have a Material  Adverse  Effect,  and (ii) is not in
violation of any order of any court, governmental authority or arbitration board
or tribunal;

                  (b) the  Guarantor  has the power and  authority  to  execute,
deliver and perform each of the  Transaction  Agreements  to which he is a party
(including, without limitation, this Guaranty);

                  (c)  no  consent  of  any  other  Person  and  no  consent  or
authorization of, filing with or other act by or in respect of, any Governmental
Entity or any  other  Person  is  required  in  connection  with the  execution,
delivery or performance by the Guarantor,  or the validity or enforceability of,

limitation, this Guaranty), except for consents, authorizations, filings or acts
which have been made or obtained,  as the case may be, and are in full force and
effect;

                  (d) the  Transaction  Agreements  to which the  Guarantor is a
party (including, without limitation, this Guaranty) have been duly executed and
delivered  by  the  Guarantor  and  constitute  the  legal,  valid  and  binding
obligations  of the  Guarantor  enforceable  against the Guarantor in accordance
with  their  respective  terms,  except  as  enforceability  may be  limited  by
applicable bankruptcy,  insolvency,  reorganization,  moratorium or similar laws
affecting  the  enforcement  of  creditors'  rights  generally  and  by  general
equitable  principles (whether enforcement is sought by proceedings in equity or
at law);

                  (e) the execution,  delivery and  performance by the Guarantor
of the  Transaction  Agreements  to which the  Guarantor is a party  (including,

regulation  or  ordinance or any order,  writ,  junction or decree of any court,

inconsistent  with or result in any  breach  of,  any of the  terms,  covenants,
conditions  or  provisions  of, or  constitute a default  under,  or (other than

or  imposition  of (or the  obligation to create or impose) any lien upon any of
the property or assets of the Guarantor  pursuant to the terms of any indenture,
mortgage,  deed of trust,  loan  agreement,  credit  agreement or other material
agreement or other  instrument  to which the Guarantor is a party or by which he
or any of its property or assets is bound or to which he may be subject; and


                                      -7-

                  (f) except as disclosed in the Agreement, there are no pending
or threatened litigations,  arbitrations,  actions or proceedings relating to of
affecting  the Guarantor  which could  reasonably be expected to have a Material
Adverse Effect.

         13.  The  Guarantor  covenants  and  agrees  that on and after the date
hereof and until the  Obligations  (other than  indemnities in the Agreement and
analogous  provisions in the Transaction  Agreements  which are not then due and
payable)  have been paid in full,  and the Agreement  has been  terminated,  the
Guarantor  shall take,  or will  refrain  from  taking,  as the case may be, all
actions that are  necessary to be taken or not taken so that no violation of any
provision,  covenant or  agreement  contained in the  Agreement,  and so that no
Event of  Default,  is  caused by the  actions  of the  Guarantor  or any of its
Obligors.

         14. The  Guarantor  hereby  agrees to pay all costs and expenses of the
Agent and each  Beneficiary in connection  with the enforcement of this Guaranty
and any  amendment,  waiver  or  consent  relating  hereto  (including,  without
limitation,  the reasonable fees and  disbursements  of counsel  employed by the
Agent or any Beneficiary).

         15.  This  Guaranty  shall  be  binding  upon  the  Guarantor  and  its
successors  and  assigns  and shall  inure to the  benefit  of the Agent and the
Beneficiaries and their respective successors and assigns.

         16. None of the terms or  provisions  of this  Guaranty may be amended,
supplemented or otherwise  modified except by a written  instrument  executed by
the Guarantor and the Agent, provided that any provision of this Guaranty may be

or facsimile transmission from the Agent.

         17. The Guarantor  acknowledges that an executed (or conformed) copy of
the Agreement and each Transaction  Agreement has been made available to him and
he is familiar with the contents thereof.

         18. In addition to any rights now or hereafter granted under applicable
law  (including,  without  limitation,  Section  151 of the New York  Debtor and
Creditor  Law)  and  not by way of  limitation  of any  such  rights,  upon  the
occurrence and during the continuance of an Event of Default,  the Agent and the
Beneficiaries  are hereby  authorized at any time or from time to time,  without
notice to the Guarantor or to any other Person,  any such notice being expressly
waived, to set off and to appropriate and apply any and all deposits (general or

irrespective of whether or not the Agent or such Beneficiary shall have made any

         21. This Guaranty shall be governed by and construed in accordance with
the laws of the State of New York applied to  contracts  to be performed  wholly

                                ESCROW AGREEMENT



                  ESCROW AGREEMENT dated as  of the [ ] day of [     ], 1999, by
                  and between

                  MICHAEL F. ZINN, having  an  office  at  1151  Flatbush  Road,
                  Kingston, New York 12401 (the "Guarantor");

                  ROBINSON BROG LEINWAND GREENE GENOVESE & GLUCK P.C.,
                  having its  office  at  1345 Avenue of the Americas, New York,
                  New York  10105 (the "Agent") and

                  [                 ]  (the "Escrow Agent").

                                               W I T N E S S E T H:

                  WHEREAS, Besicorp Holdings, Ltd., Besi Acquisition Corp.
(together,  "Purchaser") and  Besicorp  Ltd. (the "Buyer") are  parties  to  an
 amended and restated agreement and plan of merger dated November 24, 1999, (the
 "Agreement"); and

                  WHEREAS, the Agreement contemplates the execution and delivery
of a Guaranty by the Guarantor for the benefit of the Agent; and

                  WHEREAS, the Guaranty  contemplates the execution and delivery
of an Escrow Agreement by the parties hereof.

                  NOW, THEREFORE, the parties hereto agree as follows:

                  1. Capitalized terms used herein without definition shall have
the same meaning as ascribed to them in the Agreement.

                  2. Escrow Agent  acknowledges  the receipt  from  Guarantor of
$100,000  (the "Escrow  Funds") and agrees to hold and disburse the Escrow Funds
pursuant to the terms hereof. The Escrow Funds shall be deposited and maintained
by Escrow Agent in an interest-bearing  bank account at Bankers Trust Company or
another nationally recognized financial  institution.  Escrow Agent shall not be
responsible  for any  interest  earned  on the  Escrow  Funds,  except  for such
interest


<PAGE>

as is  actually  received,  nor for the loss of any  interest  arising  from the
withdrawal of the Escrow Funds prior to the date of maturity of any deposit.

                  3. (a) The  parties  acknowledge  that the Escrow  Funds shall
serve  as a  source  of  funding  for  amounts  owing  by the  Guarantor  to the
Beneficiaries (as such term is defined in the Guaranty) pursuant to Section 2(b)
of the Guaranty  ("Claims").  If the Agent shall request a disbursement from the
Escrow Fund  associated  with any Claim,  it shall give  notice of such  request
executed by Agent,  to the Escrow  Agent and  Guarantor,  which notice shall set
forth  the  amount  requested,  the  basis  for  such  request,  and  reasonable
documentation  to support such request (such notice being  substantially  in the
form of Exhibit A hereto).The  Escrow Agent shall disburse the amount  requested
within 10 days of its receipt of the notice in the event the Escrow  Agent shall
not have received a notice of objection  from Guarantor  within such period.  In
the event the Escrow Agent shall receive a timely  notice of objection  from the
Guarantor,  it shall not  disburse  the  amount  requested  until it shall  have
received (i) the joint  written  notice of the Guarantor and Agent setting forth
the joint direction of such parties (such notice being substantially in the form
of  Exhibit  B  hereto),  (ii) a  written  instrument  representing  a final and
non-appealable  order or similar  direction  with respect to the  disposition of
such amount issued by the arbitrator or arbitration  forum, or (iii) a certified
copy of a final and non-appealable judgment of a court of competent jurisdiction
directing  the  disbursement  of such  funds;  the  Escrow  Agent  shall also be
entitled to deposit  such Escrow  Funds with the clerk of the court in which any
litigation  between the parties is pending,  or with the clerk of an appropriate
court in New York, New York). Notwithstanding the foregoing, the Guarantor shall
not  unreasonably  withhold its consent to a request by the Agent for payment of
Claims.

         (b) At any time following the sixth anniversary of the date hereof that
all Claims that have been set forth in notices  provided  under Sections 3(a) of
this Agreement  have been settled and paid in accordance  with the provisions of
Section  3(a), no such claims remain  outstanding,  and that, in the  reasonable
judgement of Buyer,  no future  Claims are  foreseeable,  Guarantor  may, at its
option,  notify the Escrow Agent and the Agent that all of such  conditions have
been  fulfilled.  In the event the Escrow Agent shall not have received a notice
of objection from the Agent with 30 days after delivery of such notice, it shall
be  required  to  disburse  all  amounts  then  remaining  in the Escrow Fund to
Guarantor and this Agreement shall terminate. In the event that the Escrow Agent
shall receive a timely notice of objection from the Agent, it shall not disburse
any  portion  of the Escrow  Fund and shall  disburse  the  Escrow  Fund only in
accordance with the provisions of the fourth sentence of Section 3(a) hereof.

                  4.  Escrow  Agent  shall  not be  liable  in any way or to any
person for its refusal to comply with adverse claims and demands being made upon
it, and shall not be responsible  for any act or failure to act on its part, nor
shall it have any liability under this Escrow  Agreement,  except in the case of
willful default or gross  negligence.  This Escrow Agreement shall terminate and
Escrow  Agent  shall  be  automatically  released  from all  responsibility  and
liability  upon  Escrow  Agent's  delivery  or deposit  of the  Escrow  Funds in
accordance with the provisions of this Escrow Agreement.

                  5. Escrow  Agent or any member of its firm shall be  permitted
to act as counsel  for  Purchaser  in any  dispute or  question as to any matter
arising out of the Agreement or this Escrow Agreement.

                  6. Escrow Agent may resign or be  discharged  at any time and,
in such event,  shall  deliver the Escrow  Funds  pursuant to the joint  written
instructions of Guarantor and Agent or, in the absence of such instructions, may
deposit the Escrow Funds with the clerk of an appropriate court in New York, New
York.

                  7. Escrow Agent shall be indemnified by Guarantor  against any
liabilities,  damages,  losses,  costs or  expenses  incurred  by,  or claims or
charges  made  against,   Escrow  Agent  (including   reasonable  counsel  fees,
disbursements  and court  costs) by reason of its  acting or  failing  to act in
connection with any of the matters contemplated by, or in carrying out the terms
of, this Escrow  Agreement,  except as a result of its  willful  malfeasance  or
gross negligence.

                  8.  Any  notice  or  communication  pursuant  to  this  Escrow
Agreement  shall be delivered in accordance with the provisions of the Guaranty,
addressed  to  Guarantor,  and Agent and the Escrow Agent at the  addresses  set
forth above.

                  9. This Escrow  Agreement,  the Guaranty and the Agreement set
forth the  entire  understanding  of the  parties  hereto and may not be changed
orally.
