         SECTION 2.01. The Revolving Credit Loans. The Bank agrees,  on the date
of this Agreement, on the terms and conditions of this Agreement and in reliance
upon the representations and warranties set forth in this Agreement,  to lend to
the Borrower prior to the Maturity Date such amounts as the Borrower may request

         (b) Each notice given  pursuant to this Section 2.02 shall  specify the
date of such  borrowing,  the amount  thereof and  whether  such Loan is to be a
Prime Rate Loan or a Eurodollar Loan and, if such Loan or any portion thereof is
to consist of one or more Eurodollar  Loans,  the principal  amounts thereof and
Interest Period or Interest Periods with respect thereto. If no election as to a
type of Loan is specified in such  notice,  such Loan (or portion  thereof as to

Loan,  the Borrower  shall be deemed to have selected an Interest  Period of one

required  pursuant to (a) above,  (x) to  continue  any  Eurodollar  Loan into a

Rate Loan into a  Eurodollar  Loan  (subject  to  availability)  subject  to the
following:

                           (i) if a Default  or an Event of  Default  shall have
                  occurred  and be  continuing  at  the  time  of  any  proposed
                  conversion  or  continuation  only Prime  Rate Loans  shall be
                  available;

                           (ii) in the case of a  continuation  or conversion of
                  fewer than all Loans,  the aggregate  principal amount of each
                  Eurodollar  Loan  continued  or into which a Loan is converted
                  shall be in the minimum  principal amount of $10,000.00 and in
                  increased integral multiples of $10,000.00;

                  effected by each Bank applying the proceeds of the new Loan to
                  the Loan (or portion thereof) being continued or converted;

                           (iv)  if  the  new  Loan   made  as  a  result  of  a
                  continuation  or conversion  shall be a Eurodollar  Loan,  the
                  first Interest  Period with respect  thereto shall commence on
                  the date of continuation or conversion;

<PAGE>

                           (v) each  request for a  Eurodollar  Loan which shall
                  fail to state an applicable Interest Period shall be deemed to
                  be a request  for an Interest  Period of one month's  duration
                  and each  request for a  Eurodollar  Loan made when such Loans
                  are not available  shall be deemed to be a request for a Prime
                  Rate Loan;

                           (vi) in the event  that the  Borrower  shall not give
                  notice to continue a Eurodollar Loan as provided  above,  such
                  Loan shall  automatically  be converted into a Prime Rate Loan
                  at the expiration of the then current Interest Period.

         SECTION 2.03.  Revolving  Credit Note. Each Revolving Credit Loan shall
be in the  minimum  principal  amount of  $10,000.00,  and in minimum  multiples
$10,000.00 thereafter.  The Revolving Credit Note shall be dated the date hereof
and be in the principal  amount of Two Million Five Hundred  Thousand and 00/100
($2,500,000.00)  Dollars,  and shall mature on the Maturity  Date, at which time
the entire  outstanding  principal balance and all interest thereon shall be due
and  payable.  The  Revolving  Credit Note shall be entitled to the benefits and
subject to the provisions of this Agreement.

         At the time of the making of each Revolving Credit Loan and at the time
of each payment of principal thereon, the holder of the Revolving Credit Note is
hereby  authorized by the Borrower to make a notation on the schedule annexed to
the  Revolving  Credit  Note of the date and amount,  and the type and  Interest
Period of the Revolving  Credit Loan or payment,  as the case may be. Failure to
make a notation  with  respect to any  Revolving  Credit Loan shall not limit or
otherwise affect the obligation of the Borrower hereunder or under the Revolving
Credit  Note with  respect to such  Revolving  Credit  Loan,  and any payment of
principal on the Revolving  Credit Note by the Borrower shall not be affected by
the failure to make a notation thereof on said schedule.

         SECTION 2.04.  Payment of Interest on the Revolving Credit Note. (a) In
the case of a Prime  Rate  Loan,  interest  shall be payable at a rate per annum
equal to the Prime Rate. Such interest shall be payable on each Interest Payment
Date,  commencing  with the first  Interest  Payment Date after the date of such

                                      -13-
<PAGE>

Prime Rate Loan and on the Revolving  Credit  Maturity  Date.  Any change in the
rate of interest on the Revolving Credit Notes due to a change in the Prime Rate
shall take effect as of the date of such change in the Prime Rate.

         (b) In the case of a Eurodollar  Loan,  interest  shall be payable at a
rate per annum  equal to the LIBOR Rate plus two and one half (2 1/2%)  percent.
Such interest shall be payable on each Interest  Payment Date,  commencing  with
the first Interest  Payment Date after the date of such  Eurodollar  Loan and on
the Maturity Date. In the event Eurodollar  Loans are available,  the Bank shall
determine the rate of interest applicable to each requested  Eurodollar Loan for
each  Interest  Period  at  11:00  a.m.,  New  York  City  time,  or as  soon as
practicable thereafter,  two (2) Business Days prior to the commencement of such
Interest  Period and shall use its best  efforts to notify the  Borrower  of the
rate of interest so determined.  Such  determination  shall be conclusive absent
manifest error.

         SECTION  2.05.  The Term  Loans.  The Bank  agrees,  on the  terms  and
conditions  of this  Agreement  and in  reliance  upon the  representations  and
warranties  set forth in this  Agreement,  to make Term Loans to the Borrower in
the aggregate principal amount of up to Two Million ($2,000,000.00) Dollars, and
the  Borrower  agrees to  borrow  such  amount  from the Bank by  executing  and
delivering to the Bank the Term Loan Notes. The Term Loans, or portions thereof,

subject to and in accordance with Section 2.06 hereof.

Term Loan  bearing  interest at the Fixed Rate,  and (ii) prior to 11:00 a.m. on
the day of each Term Loan consisting solely of a Prime Rate Loan. If a notice of
borrowing  is  received by the Bank after  11:00 a.m.  on a Business  Day,  such
notice shall be deemed to have been given on the next succeeding Business Day.

         (b) Each notice given  pursuant to this Section 2.06 shall  specify the
date of such  borrowing and the amount  thereof and whether such Loan is to be a
Prime  Rate Loan or a Fixed Rate Loan.  If no  election  as to a type of Loan is
specified in such notice,  such Loan (or portion thereof as to which no election

to the Bank  (immediately  confirmed  in writing) of such  prepayment  provided,
however, that each such prepayment shall be on a Business Day and shall be in an
aggregate principal amount which is an integral multiple of $10,000.00.

         (b) The  Borrower  shall  have the  right at any time and from  time to

discounting) of: (i) the difference,  if positive,  between the interest rate on
the Term Loan Note being  prepaid and the yield on the  Prepayment  Date on U.S.
Treasury  Securities  (the  "Treasury  Rate") as  published  in the Wall  Street
Journal with the closest  matching  maturity to the Term Loan  Maturity  Date of
such Note, multiplied by (ii) the total amount of principal prepaid,  divided by
(iii) 360 and multiplied by (iv) the actual number of days remaining  until such
Term Loan Maturity Date. In addition,  all  prepayments  shall be accompanied by
any and all additional  administrative costs incurred by the Bank (as determined
by the  Bank  in its  sole  discretion)  as a  result  of such  prepayment.  All
prepayments shall be applied in inverse order of maturity.

                                       -17-
<PAGE>

         (d) The notice of  prepayment  under this  Section 2.14 shall set forth
the prepayment date and the principal amount of the Loan being prepaid and shall
be  irrevocable  and shall commit the Borrower to prepay such Loan by the amount
and on the date stated therein.  All prepayments shall be accompanied by accrued
interest on the principal  amount being prepaid to the date of prepayment.  Each
prepayment  under  this  Section  2.14  shall be applied  first  towards  unpaid
interest on the amount being  prepaid and then towards the principal in whole or
partial  prepayment  of Loans by the Borrower.  Eurodollar  Loans may be prepaid

may be prepaid only in accordance with the provisions of paragraph (c) above.

prepayment  or  conversion  (whether  voluntarily  or by  acceleration)  of  any
Eurodollar Loan other than on the last day of the Interest Period for such Loan,
or if the Borrower fails to borrow the Eurodollar Loan (or is not able to borrow
because of an Event of Default or for any other reason  hereunder)  after having
given the  irrevocable  notice of  borrowing  required by this  Agreement.  Such
reimbursement  shall include,  but not be limited to, any loss,  cost or expense
incurred by the Bank in obtaining,  liquidating or redeploying any funds used or
to be used in making or maintaining the Eurodollar Loan.

         SECTION 2.16.  Eurocurrency Reserve Requirement.  It is understood that
the cost to the Bank of making or maintaining  Eurodollar Loans may fluctuate as
a result of the  applicability  of,  or  change  in,  the  Eurocurrency  Reserve
Requirement.  The  Borrower  agrees  to pay to the Bank  from  time to time,  as
provided in Section 2.17 below, such amounts as shall be necessary to compensate
the Bank for the cost of making or maintaining  any Eurodollar  Loans made by it
resulting  from any change in the  Eurocurrency  Reserve  Requirement,  it being
understood that the rates of interest  applicable to Eurodollar  Loans hereunder
have been  determined on the basis of the  Eurocurrency  Reserve  Requirement in
effect at the time of determination of the LIBOR Rate and that such rates do not
reflect  costs  imposed  on the  Bank  in  connection  with  any  change  to the

                                      -18-

Eurocurrency  Reserve  Requirement.  It is  agreed  that  for  purposes  of this
paragraph  the  Eurodollar  Loans made  hereunder  shall be deemed to constitute
Eurocurrency  Liabilities  as defined in  Regulation  D and to be subject to the
reserve  requirements  of  Regulation D without  benefit or credit of proration,
exemptions or offsets  which might  otherwise be available to the Bank from time
to time under Regulation D.

         SECTION 2.17.  Increased  Costs.  If, after the date of this Agreement,
the  adoption  of, or any change in, any  applicable  law,  regulation,  rule or
directive,  or any  interpretation  thereof by any  authority  charged  with the
administration or interpretation thereof:

                  (i)  subjects  the  Bank  to  any  tax  with  respect  to  its
Commitment,  the Loans,  the Notes or on any amount  paid or to be paid under or
pursuant to this Agreement,  the Loans or the Notes (other than any tax measured
by or based upon the overall net income of the Bank);

                  (ii)  changes the basis of taxation of payments to the Bank of
any amounts payable  hereunder (other than any tax measured by or based upon the
overall net income of the Bank);

                  (iii)  imposes,  modifies  or deems  applicable  any  reserve,
capital  adequacy or deposit  requirements  against any assets held by, deposits
with or for the account of, or loans made by, the Bank; or

                  (iv)  imposes on the Bank any other  condition  affecting  its
Commitment, the Loans, the Notes or this Agreement; and the result of any of the
foregoing is to increase the cost to the Bank of  maintaining  this Agreement or
the  Commitment  or making  the Loans,  or to reduce  the amount of any  payment
(whether of  principal,  interest  or  otherwise)  receivable  by the Bank or to
require the Bank to make any payment on or  calculated by reference to the gross
amount of any sum  received  by it, in each case by an amount  which the Bank in
its reasonable judgment deems material, then and in any such case:

                  (a) the Bank shall promptly advise the Borrower of such event,
         together with the date thereof,  the amount of such  increased  cost or
         reduction  or  payment  and the  way in  which  such  amount  has  been
         calculated; and

                                      -19-
<PAGE>

                  (b) the Borrower  shall pay to the Bank,  within ten (10) days
         after the advice  referred to in subsection  (a)  hereinabove,  such an
         amount or amounts as will compensate the Bank for such additional cost,
         reduction or payment for so long as the same shall remain in effect.

                  The determination of the Bank as to additional amounts payable
pursuant to this  Section  2.17 shall be  conclusive  evidence  of such  amounts
absent manifest error.

         SECTION 2.18. Capital Adequacy.  If the Bank shall have determined that
the  applicability  of any law, rule,  regulation or guideline,  or the adoption
after the date hereof of any other law, rule,  regulation or guideline regarding
capital adequacy, or any change in any of the foregoing or in the interpretation
or administration of any of the foregoing by any governmental authority, central
bank or comparable  agency  charged with the  interpretation  or  administration
thereof,  or compliance  by the Bank (or any lending  office of the Bank) or the
Bank's holding company with any request or directive  regarding capital adequacy
(whether or not having the force of law) of any such authority,  central bank or
comparable  agency,  has or would have the effect of reducing the rate of return
on the Bank's capital or on the capital of the Bank's holding  company,  if any,
as a consequence  of its  obligations  hereunder to a level below that which the
Bank or the Bank's  holding  company could have achieved but for such  adoption,
change or  compliance  (taking into  consideration  the Bank's  policies and the
policies of the Bank's holding  company with respect to capital  adequacy) by an
amount  deemed by the Bank to be  material,  then from time to time the Borrower
shall pay to the Bank such  additional  amount or amounts as will compensate the
Bank or the Bank's holding company for any such reduction suffered.

         SECTION 2.19. Change in Legality.  (a) Notwithstanding  anything to the
contrary  contained  elsewhere in this  Agreement,  if any change after the date
hereof in law, rule,  regulation,  guideline or order, or in the  interpretation
thereof by any governmental  authority charged with the administration  thereof,
shall make it unlawful for the Bank to make or maintain any  Eurodollar  Loan or

                                      -20-
<PAGE>

to give effect to its  obligations  as  contemplated  hereby  with  respect to a
Eurodollar Loan, then, by written notice to the Borrower, the Bank may:

                  (i) declare that Eurodollar  Loans will not thereafter be made
         hereunder,  whereupon the Borrower shall be prohibited  from requesting
         such Eurodollar Loans hereunder unless such declaration is subsequently
         withdrawn; and

                (ii) require  that,  subject to the  provisions of Section 2.15,
         all  outstanding  Eurodollar  Loans made by it be  converted to a Prime
         Rate  Loan,   whereupon   all  of  such   Eurodollar   Loans  shall  be
         automatically  converted to a Prime Rate Loan as of the effective  date
         of such notice as provided in paragraph (b) below.

                  (b) For  purposes  of  this  Section  2.19,  a  notice  to the
Borrower by the Bank pursuant to paragraph (a) above shall be effective, for the
purposes of paragraph (a) above,  if lawful,  and if any Eurodollar  Loans shall
then be  outstanding,  on the  last  day of the then  current  Interest  Period;
otherwise,  such  notice  shall  be  effective  on the  date of  receipt  by the
Borrower.

         SECTION 2.20.  Indemnity.  The Borrower will indemnify the Bank against
any loss or expense which the Bank may sustain or incur as a consequence  of any
default in payment or prepayment of the principal amount of any Loan or any part
thereof or  interest  accrued  thereon,  as and when due and payable (at the due
date thereof,  by notice of prepayment or  otherwise),  or the occurrence of any
Event of Default,  including but not limited to any loss or expense sustained or
incurred in  liquidating  or employing  deposits from third parties  acquired to
affect or  maintain  such Loan or any part  thereof.  When  claiming  under this
Section 2.20,  the Bank shall provide to the Borrower a statement,  signed by an
officer  of the  Bank,  explaining  the  amount  of any  such  loss  or  expense
(including  the  calculation  of such amount),  which  statement  shall,  in the
absence of manifest error, be conclusive with respect to the parties hereto.

         SECTION 2.21. Change in LIBOR; Availability of Rates. In the event, and
on each occasion,  that, on the day the interest rate for any Eurodollar Loan is
to be  determined,  for  a  requested  Eurodollar  Loan,  the  Bank  shall  have
determined (which determination,  absent manifest error, shall be conclusive and
binding upon the Borrower)  that dollar  deposits in the amount of the principal

                                      -21-
<PAGE>

amount of the  requested  Eurodollar  Loan are not  generally  available  in the
London  Interbank  Market,  or that the rate at which such dollar  deposits  are
being  offered will not  adequately  and fairly  reflect the cost to the Bank of
making or maintaining  the principal  amount of such Eurodollar Loan during such
Interest Period, such Eurodollar Loan shall be unavailable,  Loans based on such
rate shall be unavailable.  The Bank shall,  as soon as practicable  thereafter,
given   written,   telex  or  telephonic   notice  of  such   determination   of
unavailability  to the Borrower.  Any request by the Borrower for an unavailable
Eurodollar  Loan  shall be deemed to have been a request  for a Prime Rate Loan.
After such notice  shall have been given and until the Bank shall have  notified
the Borrower that the circumstances  giving rise to such notice no longer exist,
each subsequent request for an unavailable Eurodollar Loan shall be deemed to be
a request for a Prime Rate Loan.

         SECTION 2.22.  Authorization to Debit Borrower's  Account.  The Bank is
hereby authorized to debit the Borrower's  account  maintained with the Bank for
(i) all scheduled  payments of principal  and/or  interest under the Notes,  and
(ii) the commitment fee and all other amounts due hereunder;  all such debits to
be made on the days such payments are due in accordance with the terms hereof.

         SECTION 2.23. Late Charges, Default Interest. (a) If the Borrower shall
default in the payment of any principal  installment  of or interest on any Loan
or any other amount becoming due hereunder,  the Borrower shall pay interest, to
the extent  permitted by law, on such defaulted  amount up to the date of actual
payment (after as well as before  judgment) at a rate per annum (computed on the
basis of the actual  number of days  elapsed  over a year of 360 days)  equal to
three (3%)  percent in excess of the  interest  rate  otherwise  in effect  with
respect to the type of Loan in connection with which the required  payments have
not been made.

         (b) Upon the  occurrence  and  during the  continuation  of an Event of
Default,  the Borrower  shall pay interest on all amounts  owing under the Notes
and this  Agreement  (after  as well as  before  judgment)  at a rate per  annum
(computed  on the basis of the actual  number of days elapsed over a year of 360
days) equal to three (3%)  percent in excess of the interest  rate  otherwise in
effect hereunder.

                                      -22-
<PAGE>

         SECTION 2.24. Payments. All payments by the Borrower hereunder or under
the Notes shall be made in Dollars in immediately  available funds at the office
of the Bank by 12:00 noon,  New York City time on the date on which such payment
shall be due.  Interest on the Notes shall accrue from and including the date of
each  Loan to but  excluding  the  date on  which  such  Loan is paid in full or
refinanced with a Loan of a different type.

         SECTION  2.25.  Interest  Adjustments.  (a) If the  provisions  of this
Agreement  or the  Notes  would at any time  otherwise  require  payment  by the
Borrower to the Bank of any amount of  interest in excess of the maximum  amount
then permitted by applicable  law the interest  payments shall be reduced to the
extent  necessary so that the Bank shall not receive  interest in excess of such
maximum amount. To the extent that, pursuant to the foregoing sentence, the Bank
shall receive interest  payments  hereunder or under the Notes in an amount less
than the  amount  otherwise  provided,  such  deficit  (hereinafter  called  the
"Interest Deficit") will cumulate and will be carried forward (without interest)
until the termination of this Agreement.  Interest otherwise payable to the Bank
hereunder  and under the Notes for any  subsequent  period shall be increased by
such maximum amount of the Interest Deficit that may be so added without causing
the Bank to receive  interest in excess of the maximum  amount then permitted by
applicable law.

         (b) The amount of the Interest Deficit shall be treated as a prepayment
penalty and paid in full at the time of any optional  prepayment by the Borrower
to the  Bank of all  outstanding  Loans.  The  amount  of the  Interest  Deficit
relating to the Notes at the time of any  complete  payment of the Notes at that
time outstanding (other than an optional  prepayment thereof) shall be cancelled
and not paid.

         SECTION 2.26. Participations, Etc. The Bank shall have the right at any
time,  with or without  notice to the  Borrower,  to sell,  assign,  transfer or
negotiate all or any part of the Term Loan Notes or the Revolving Credit Note or
the Commitment or grant participations  therein to one or more banks (foreign or
domestic,  including  an affiliate  of the Bank),  insurance  companies or other
financial  institutions,  pension  funds or mutual  funds.  The Borrower and the
Guarantors  agree  and  consent  to  the  Bank  providing  financial  and  other

                                      -23-

information regarding their business and operations to prospective purchasers or
participants  and further  agree that to the extent  that the Bank should  sell,
assign,  transfer or negotiate  all or any part of the Notes or the  Commitment,
the Bank shall be forever released and discharged from its obligations under the
Notes,  the Commitment and this Agreement to the extent same is sold,  assigned,
transferred  or  negotiated.  Nothing  herein  shall  be  read or  construed  as
prohibiting or otherwise limiting the ability or right of the Bank to pledge any
Note to a Federal Reserve Bank.

the fiscal year ended December 31, 1999,  copies of which have been furnished to
the Bank, fairly present in all material respects the financial condition of the
Borrower and  Guarantors  as at such date and the results of  operations  of the
Borrower and  Guarantors  for the period ended on such date,  all in  accordance

         (h) Tax Returns.  Except as set forth on Schedule  4.01(h) hereto,  the
Borrower and each  Guarantor has filed all federal,  state and local tax returns

         (k) Margin Credit. Neither the Borrower nor any Guarantor is engaged in
the  business  of  extending  credit for the purpose of  purchasing  or carrying
margin stock (within the meaning of Regulation G, T, U or X), and no proceeds of
any Loan will be used to purchase or carry any margin stock or to extend  credit
to others for the purpose of  purchasing  or carrying any margin stock or in any
other  way which  will  cause the  Borrower  or any  Guarantor  to  violate  the
provisions of Regulations G, T, U or X.

         (l)  Securities  Exchange  Act. No proceeds of any Loan will be used to
acquire any security in any transaction which is subject to Sections 13 or 14 of

hereto,  the Borrower,  each  Guarantor and each  Subsidiary are in all material
respects in compliance  with all federal and state laws and  regulations  in all

Subsidiary.

demand, protest or further notice of any kind, all of which are hereby expressly
waived by the Borrower and (ii) proceed to enforce its rights whether by suit in
equity or by action at law, whether for specific  performance of any covenant or
agreement  contained in this  Agreement or any Loan  Document,  or in aid of the
exercise of any power  granted in either this  Agreement or any Loan Document or
proceed to obtain  judgment or any other relief  whatsoever  appropriate  to the
enforcement  of its rights,  or proceed to enforce any other legal or  equitable
right  which  the Bank may have by  reason  of the  occurrence  of any  Event of

Document or now or hereafter  existing at law or in equity. No delay or omission
to exercise any right or power  accruing  upon any Event of Default shall impair
any such right or power or shall be  construed to be a waiver  thereof,  but any
such right and power may be  exercised  from time to time and as often as may be

                                      -47-

Loan  Document,  shall  operate  as a waiver  thereof;  nor shall any  single or
