                                      NOTE


U.S.$19,000,000                                    DATED AS OF NOVEMBER 4, 1996


         FOR VALUE RECEIVED, the undersigned promises to pay to the order of
Deutsche Bank AG (the "Bank") New York and/or Cayman Islands Branches in lawful
money of the United States of America and in immediately available funds the
principal amount of Nineteen Million United States Dollars (U.S.$19,000,000)
or, if less, the unpaid principal amount of all loans made by the Bank's New
York Branch or Cayman Islands Branch to the undersigned from time to time, at
the principal office of Deutsche Bank AG New York Branch, New York, New York,
on the dates endorsed on the schedule (the "Grid") attached hereto.

         The undersigned also promises to pay interest on the unpaid principal
amounts made available by the Bank hereunder prior to maturity at the rates per
annum set forth on the Grid.  The undersigned hereby promises to pay the Bank
interest, payable upon demand, on any amount of principal and, to the extent
permitted by law, interest, remaining unpaid hereunder after maturity (whether
by acceleration or otherwise) until paid in full at a rate equal to 2% plus the
Bank's Base Rate.  "Base Rate" shall mean a fluctuating interest rate per
annum equal to the higher of the Bank's Prime Lending Rate or 0.50% above the
Bank's Overnight Federal Funds Rate.  "Prime Lending Rate" shall mean the rate
announced by the Bank from time to time as its prime lending rate for unsecured
commercial loans within the United States (but is not intended to be the lowest
rate of interest charged by the Bank in connection with extensions of credit to
debtors).  "Overnight Federal Funds Rate" shall mean the rate per annum at
which the New York Branch of the Bank, as a branch of a foreign bank, in its
sole discretion, can acquire federal funds in the interbank overnight federal
funds market including through brokers of recognized standing.  Any change in
the interest rate resulting from a change in the Base Rate shall take effect at
the time of such change in the Base Rate.  Interest shall be based on the bank
basis of a year of 360 days and the exact number of days elapsed.  Interest
shall commence to accrue on the date of each loan and be payable in lawful
money of the United States of America at the office of the Bank listed above on
each such loan's maturity date stated on the Grid (unless such loan has a
maturity greater than three months in which event interest shall also be
payable quarterly in arrears).  The undersigned authorizes the Bank to debit
its account with the Bank's New York Branch with respect to all payments
hereon.

         At the time of the making of any loan hereunder and upon each
repayment of principal the Bank shall, and is hereby authorized to, make a
notation on the Grid of the date and the amount and maturity of each such loan,
the interest rate applicable thereto, and each principal repayment.  However,
the failure to make any such notation shall not limit or otherwise affect the
undersigned's obligations hereunder with respect to any such loan or repayment
of principal.  Although this Note is dated the date of issue, interest in
respect hereof shall be payable only for the period during which the loans
evidenced hereby are outstanding and, although the stated amount hereof may be
higher, this Note shall be enforceable, with respect to the undersigned's
obligation to pay the principal amount hereof, and interest hereon, only to the
extent of the unpaid principal amount of loans and accrued and unpaid interest
evidenced hereby.

         The term "Liabilities" shall include the liability evidenced by this
Note and all other liabilities, direct or contingent, joint, several or
independent, of the undersigned now or hereafter existing, due or to become due
to, or held or to be held by, the Bank, whether created directly or acquired by
assignment or otherwise.
<PAGE>   7

         Upon the occurrence of any of the following events (each an "Event of
Default"): (i) nonpayment when due of any of the Liabilities; (ii) any
representation in any financial or other statement of the undersigned delivered
to the Bank by or on behalf of the undersigned being untrue or omitting any
material fact; (iii) the failure of the undersigned or any of its subsidiaries
to generally pay its debts as they come due or the admission in writing by the
undersigned or any of its subsidiaries of its inability to pay its debts
generally, or the making by the undersigned or any of its subsidiaries of an
assignment for the benefit of creditors, or the institution of any proceeding
by or against the undersigned or any of its subsidiaries seeking to adjudicate
it a bankrupt or insolvent, or seeking liquidation, winding up, reorganization,
arrangement, adjustment, protection, relief or composition of it or its debts
under any law relating to bankruptcy, insolvency or reorganization or relief of
debtors, or the appointment of a receiver, trustee, custodian or other similar
official for the undersigned or any of its subsidiaries or for any substantial
part of the property of the undersigned or any of its subsidiaries and, in the
case of institution of any such proceeding against the undersigned or any of
its subsidiaries, either such proceeding remaining undismissed or unstayed for
a period of 30 days or any of the actions sought in the proceeding occurring,
or the undersigned or any of its subsidiaries taking any corporate or other
authorizing action in respect of the foregoing; (iv) failure of the undersigned
or any of its subsidiaries to pay when due any principal, interest, premium, or
other amount owing with respect to any of its indebtedness for borrowed money
(including guarantees thereof) or any other event occurring or condition
existing and continuing after any applicable grace period, the effect of which
is to accelerate or to permit the acceleration of the maturity of such
indebtedness; (v) any judgment or order for the payment of money shall be
rendered against the undersigned or any of its subsidiaries and shall remain
unpaid or unsatisfied for a period of 10 days; (vi) the undersigned becoming a
party to any merger, consolidation, or sale of all or substantially all of its
assets without the prior written consent of the Bank; (vii) failure of the
undersigned or any of its subsidiaries to perform any agreement with the Bank;
(viii) a change in the condition or the affairs of the undersigned or any of
its subsidiaries such that, in the opinion of the Bank, its credit risk is
increased or the Bank deems itself insecure for any other reason; or (ix) there
shall occur any change in the ownership of the undersigned which, in the
opinion of the Bank, is material; THEN AND IN ANY SUCH EVENT, the Bank in its
discretion may, by written notice to the undersigned, declare the principal of
and accrued interest on all Liabilities to be, whereupon the same shall become,
forthwith due and payable, without presentment, demand, protest or other notice
of any kind, all of which are hereby expressly waived by the undersigned,
provided, that upon the occurrence of any event specified in clause (iii) with
respect to the undersigned such amounts shall automatically become and be due
and payable, without presentment, demand, protest or any notice of any kind,
all of which are hereby expressly waived by the undersigned.

         In the case of any non-payment when due of any Liabilities, the
undersigned shall pay all costs and expenses of every kind for collection,
including all attorneys' fees.

         In the event that a determination is made by the Bank in its sole
discretion that reserves must be maintained with any Federal Reserve Bank of
the United States, with any other governmental authority whatsoever or
otherwise pursuant to any Regulation of the Board of Governors of the Federal
Reserve System or otherwise, in connection with the loans evidenced hereby or
the funding thereof the undersigned agrees to pay and hold the Bank harmless
from and against the cost of acquiring and/or maintaining any such reserves.
If any principal payment hereunder is made for any reason whatsoever on a date
other than the maturity date, the undersigned (i) shall pay interest accrued
thereon and (ii) shall on demand indemnify the Bank against all losses, 
including loss of profit and expenses, suffered by it in liquidating or
otherwise employing deposits acquired to fund such loans until the stated
maturity. A certificate of the Bank as to the amount required to be paid by the
undersigned under this paragraph shall accompany such demand and shall be,
except in the case of manifest error or in the absence of good faith, final and
conclusive.

         In the event that a determination is made by the Bank in its sole
discretion that the adoption of any applicable law, rule or regulation
regarding capital adequacy, or any change therein or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by the Bank 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 as a consequence of its
obligations to the undersigned or of the loans to the undersigned evidenced
hereby to a level below that which the Bank could have achieved but for such
adoption, change, or compliance, the undersigned promises to pay on demand to
the Bank such additional amount or amounts as will compensate the Bank for such
reduction.  A certificate of the Bank as to the amount required to be paid by
the undersigned under this paragraph shall accompany such demand and shall be,
except in the case of manifest error or in the absence of good faith, final and
conclusive.

         All payments to be made hereunder by the undersigned shall be made
without set-off or counterclaim and in such amounts as may be necessary in
order that every such payment (after deduction or withholding for or on account
of any present or future taxes, levies, imposts, duties or other charges of
whatever nature imposed by the country of the undersigned or any political
subdivision or taxing authority therein or thereof) shall not be less than the
amounts otherwise specified to be paid hereunder.

         No delay on the part of the Bank in exercising any of its options,
powers or rights, or partial or single exercise thereof, shall constitute a
waiver thereof.  The options, powers and rights of the Bank specified herein
are in addition to those otherwise created.

         This Note shall supersede and replace the Note dated as of March 29,
1996 the ("Old Note") and all amounts outstanding under the Old Note shall be
deemed to be outstanding under this Note.

         THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK.  EACH OF THE UNDERSIGNED AND THE BANK HEREBY
IRREVOCABLY WAIVES ALL RIGHT OF TRIAL BY JURY IN ANY ACTION, PROCEEDING OR
COUNTERCLAIM ARISING OUT OF OR IN CONNECTION WITH THIS NOTE OR ANY MATTER

unconditionally promises to pay to the order of BAYERISCHE HYPOTHEKENUND
WECHSEL - BANK AKTIENGESELLSCHAFT, acting through its New York Branch
("Lender"), at its office at 32 Old Slip, Financial Square, 32nd Floor, New
York, New York 10005, or any other branch or office of Leader which it shall
designate) the principal sum of Fourteen Million United States Dollars (U.S.
$14,000,000.00) ("Principal") on March 25, 1997, ("Maturity Date") and to pay
interest thereon, to the extent permitted by applicable law, at per annum rates
equal to sixty five hundredths of a percent (0.65%) above LIBOR (as defined
below) for interest periods of 1, 2, 3 or 6 months (each a "LIBOR Interest
Period"), in accordance with the following.

1.  INTEREST.
(a)  "LIBOR" shall mean that rate of interest, as determined by Lender in its
sole judgment, at which, for a LIBOR Interest Period commencing on the date of
each loan ("Borrowing") and, if applicable, each successive LIBOR Interest
Period, U.S. dollar deposits in an amount equal to the outstanding Principal
shall be offered to Lender in the London Interbank market at approximately 11
a.m. London time two Business Days (as defined below) prior to the first day of
such LIBOR Interest Period, whether or not Borrower shall have notice thereof;
provided that LIBOR is available, and provided further, that each such period
shall commence on the day on which the immediately preceding period expires.
If LIBOR shall be deemed unavailable, interest shall accrue at a per annum rate
to be mutually agreed to by Lender and Borrower.  LIBOR shall be deemed
unavailable if no deposit in the amount of the outstanding Principal hereunder
based on the LIBOR Interest Period selected is readily obtainable by Lender in
the London Interbank market, as determined by Lender in its sole judgment.

(b)  As used herein, "Business Day" shall mean any day on which commercial
banks in London and New York City are open for general business.

(c)  Except as otherwise provided herein, interest shall accrue on the
outstanding Principal from the date hereof until its payment to Lender in full,
computed on the basis of a 360-day year and the actual number of days elapsed.
Accrued interest shall be paid to Lender, (i) on the Maturity Date, (ii) on the
last day of each LIBOR Interest Period, (iii) when LIBOR is longer than three
months, every three months after the Initial Day (as defined below); and (iv)
whenever else a payment of Principal shall be made or shall become payable.

(d)  Notwithstanding any provision to the contrary contained herein, (i) if the
last day of a LIBOR Interest Period falls on a day other than a Business Day,
then the last day of the LIBOR Interest Period shall be extended to fall on the
next succeeding Business Day, unless such extension would cause the last day of
the LIBOR Interest Period to occur in the next following calendar month, in
which case, the LIBOR Interest Period shall end on the immediately preceding
Business Day; (ii) if any LIBOR Interest Period begins on the last Business Day
of a calendar month (or a day for which there is no numerically corresponding
day in the calendar month at the end of such LIBOR Interest Period), then it
shall end on a day which is the last Business Day of the applicable calendar
mouth; and (iii) no LIBOR Interest Period may be selected that would end later
than the Maturity Date.

2.  PREPAYMENTS.
The Principal may be paid before the end of a LIBOR Interest Period, only if
Lender shall have given its prior written consent.  With such a prepayment,
Borrower shall also pay accrued interest and any other amounts owed to Lender
in respect of the Borrowing and shall reimburse Lender for any fee, cost,
expense or loss which Lender shall incur or suffer, in an amount to be
determined by Lender in its sole discretion, because of early payment of
Principal including, but not limited to, any fee, cost, expense or loss which
Lender shall incur in the redeployment of its funds.

                                      -2-

3.  PAYMENTS.
(a)  Each payment due under this Note shall be made in immediately available
funds at the Office of Lender or to such account as Lender may designate to
Borrower without any setoff, withholding or deduction of any kind.  Whenever
any payment to be made hereunder would without this provision be due and
payable on a day which is not a Business Day, it shall be due on the next
succeeding Business Day, except as otherwise expressly provided herein.

(b)  Lender shall apply payments received from or for the account of Borrower
first to accrued, unpaid interest due Lender and next to sums due Lender other
than Principal, notwithstanding any direction by Borrower to the contrary.

(c)  All payments of Principal, interest and any other sums due hereunder shall
be made in the amounts required hereby without any reduction or setoff (unless
based on a final judgment on which execution may be had), notwithstanding the
assertion of any right of recoupment or setoff or any counterclaim, and without
any withholding on account of taxes, levies or duties or any other deduction
whatsoever.  In the event that Borrower is required by law to withhold or to
deduct any sum from payment required hereby, Borrower shall, to the extent
permitted by applicable law, increase the amount paid by it to Lender by such
withholding or deductions as may be necessary so that Lender shall receive an
amount which after payment of any sum withheld or deducted shall be equal to
the amount that Lender would have received had such sum not been withheld or
deducted.

(d)  In the event that Borrower does not cause a payment to be made when and as
due to Lender, Lender may charge the amount due to any account of Borrower with
Lender or any other branch or any subsidiary of Lender and apply funds from
such account to the payment due, unless Lender shall have agreed expressly with
Borrower not to do so.

4.  NOTICE SELECTING LIBOR INTEREST PERIOD.
(a)  To request a LIBOR Interest Period, Borrower shall in communication to
Lender ("Interest Notice") refer to this Note and specify the duration of such
LIBOR Interest Period and the Business Day on which such LIBOR Interest Period
is to commence ("Initial Day").  To be effective, an Interest Notice must be
received by Lender at least two full business days prior to the Initial Day.
An Interest Notice not in writing shall be deemed to have been complete and in
accordance with the record Lender makes of such LIBOR Interest Period.

(b)  By requesting a LIBOR Interest Period, Borrower shall be deemed to
represent that, as of the Initial Day, the Representations and Warranties of
Section 6 hereof remain accurate and that no Event of Default (as defined
below) or an event which, with the giving of notice or the passage of time, or
both, would become an Event of Default, will result or have resulted.  No LIBOR
Interest Period shall commence unless all such Representations and Warranties
shall then be true and correct.

5.  CONDITIONS PRECEDENT.
The Principal shall not be available unless (i) all Representations and
Warranties of Borrower made in connection with this Note are true and correct,
as of the Effective Date, and (ii) Lender shall have received each of the
following in form and substance satisfactory to Lender and its counsel:

(a)  A certified copy of corporate resolutions of each of Borrower and any

with respect to this Note; and

         Strasse 84, 81379 Munich, Germany, in form and substance acceptable to
         Lender.

substitution for it shall be construed in accordance with and governed by the
laws of the State of New York applicable to agreements made and to be performed

9.  CHANGE OF CIRCUMSTANCES.
(a)  If after the date hereof there shall become effective any change in any
law or regulation, or in the application or interpretation thereof by a
governmental authority, or there shall be issued or changed any guideline
(whether or not having the force of law) by an entity charged with
responsibility therefor, including without limitation any issuance or change in
respect of reserve, capital adequacy, asset ratio, tax or similar requirements,
or if any such authority or entity shall request or direct that Lender comply
with any law, regulation or guideline or if the Lender shall commence
compliance with any law, regulation, or guideline, either in effect or expected
to become effective, and if as a result of such change, request, direction or
compliance the cost to the Lender of maintaining, or obtaining funds to
satisfy, its commitment or its other obligations regarding the transaction
represented hereby shall increase, the net income after taxes received or
receivable by the Lender in connection with this transaction shall be reduced
or the return it would receive on its capital or performance of this
transaction shall be diminished, Borrower shall compensate the Lender in the
manner requested by the Lender so that the Lender shall receive the sums or
return on its capital it could not receive because of such change, request,
direction or compliance.  The Lender's request for such compensation shall be
accompanied by a certificate setting forth the basis of its entitlement thereto
and shall be conclusive, absent manifest error.  The Lender shall not be
entitled to compensation pursuant to this provision because of an increase in
tax rates applicable to its general income.

interpretation thereof, or a material change in the New York and/or London
Interbank Eurodollar market, including any changes set forth in the foregoing

become unlawful for Lender to continue such Borrowing in accordance with this
Note, or if by doing so Lender, in its sole discretion, determines that it
would be subject to material adverse operational burdens or restrictions, then
Lender shall give notice of such fact to Borrower and outstanding Principal and
accrued interest, and all other sums owed to Lender, shall forthwith become
payable and Borrower shall pay to Lender such sums as would be payable under
this Note if a prepayment were made on the date of such notice in an amount
equal to the outstanding Principal of the Borrowing and reimburse Lender for
any fee, cost, expense or loss Lender shall incur or suffer because of such
change, in an amount to be determined by Lender in its sole discretion.

10.  OTHER PROVISIONS.

other form of notice, not expressly required of Lender by this Note, that may
be required to hold Borrower liable on this Note.

(b)  Any notice or advice given to Borrower at the above address or any other
specified by it in writing shall be presumed received by Borrower immediately
if given by telex or facsimile transmission, within one day if given by
telegram, Express Mail or a recognized courier service, or within three days if
deposited, first class postage prepaid, in an official depository of the United
States Postal Service for mail to be delivered.

incurred in connection with the enforcement of this Note or
<PAGE>   14

                                      -6-

amendment of it, or any note given as a replacement or in substitution for it,
or maintenance of its rights thereunder.  Each sum due to Lender under this
Note, other than Principal and interest, shall bear interest from the date of
demand until the date of payment in full at per annum rates equal to the lesser
of two percent above the Base Rate or the maximum extent allowed by applicable
law.

(d)  In the event Lender extends credit to Borrower after the date hereof and
such extension of credit shall not be pursuant to a written agreement signed by
two officers of Lender or evidenced by a note accepted by Lender, it shall be
governed by and subject to all the provisions of this Note except that the term
and interest rate shall be as otherwise agreed.

(e)  Neither Lender nor its directors, officers, attorneys, agents or employees
shall be liable to Borrower or any Affiliate for any loss or damage caused by
any act or omission on the part of any of them unless such loss or damage shall
have been caused by the gross negligence or willful misconduct of such person,
unless such loss or damage shall have been the direct, immediate and necessary
result of such act or omission and unless such result was intended by such
person or such person knew that such loss or damage was the probable result of
his act or omission.

(f)  This Note constitutes the entire agreement with respect to the subject
matter hereof;  Borrower has not relied upon any representation of Lender in
making the Borrowing or giving this Note.  This Note supersedes all prior
agreements, understanding and arrangements, whether oral or written, regarding
the obligations of Borrower which it evidences.

(g)  This Note may not be modified or amended except by an instrument or
instruments in writing signed by the person or entity against whom enforcement
of any such modification or amendment is sought, with two officers of Lender
signing if it must sign; the waiver by Lender of any condition of, or any
breach of any term or provision of, this Note shall be limited to such instance
and shall not be construed as a waiver of the conditions generally or of any
subsequent breach.

(h) In the event any one or more of the provisions contained in this Note, any
amendment of it or any note taken as a replacement or in substitution for it,
should be invalid, illegal or unenforceable in any respect, the remaining
provisions shall not for that reason be affected or impaired in any way.

For each Borrowing the "Due Date" shall be the first to occur of the following:

two authorized officers of Lender.

As used in this note, (i) "LIBOR" shall mean the per annum rate of interest, as

requested for a Borrowing or for which LIBOR is to be determined, whether or
not Borrower shall have notice thereof; (ii) with respect to any Borrowing,

LIBOR, a day on which dealings in U.S. Dollar deposits are also carried out in

interest fixed from time to time by the management of Bayerische Vereinsbank

the extent permitted by applicable law, from the date such Borrowing is made
until the date such Borrowing shall become payable, at the fluctuating or fixed
rate per annum specified on the Schedule, and thereafter until payment in full
at the rate per annum three percent above the Base Rate, computed on the basis
of a 360-day year and the actual number of days elapsed.  Interest shall be
payable with respect to each Borrowing on its Due Date, on the last Business
Day of every third month of each Interest Period longer than 3 months, on the
<PAGE>   16

last day of each Interest Period and whenever else the principal shall become
payable.

The principal of a Borrowing may be paid before it is due only if Lender shall

interest and any other amounts owed to Lender in respect of the Borrowing and
shall reimburse Lender for any fee, cost, expense or loss Lender shall incur or
suffer because of such early payment.

Borrower represents that (a) it has full power and authority, not restricted by
any law or governmental regulation, to execute and deliver this note and to
perform hereunder; (b) this note evidences its valid and legally binding
obligation, enforceable in accordance with its terms; and (c) its execution,
delivery and performance of this note do not and will not contravene any
contractual restriction binding on or affecting it.

BORROWER ADMITS THAT LENDER HAS NOT COMMITTED ITSELF TO EXTEND ANY CREDIT TO
BORROWER OR TO DO SO ON ANY SPECIFIC TERMS OR AT ANY PARTICULAR INTEREST RATE,
MARGIN OR BASIS, THAT LENDER SHALL HAVE NO OBLIGATION TO MAKE ANY NEW BORROWING
OR TO RENEW ANY BORROWING HEREUNDER AT ANY TIME, ON ANY SPECIFIC TERMS OR AT ANY
PARTICULAR INTEREST RATE, MARGIN OR BASIS, AND THAT LENDER MAY DECLINE TO MAKE
OR RENEW A REQUESTED BORROWING OR OFFER TO DO SO ON ANY TERMS OR AT ANY
INTEREST RATE, MARGIN OR BASIS WITH OR WITHOUT SUFFICIENT REASON WITHOUT ANY
LIABILITY ARISING THEREFOR.  BORROWER WILL NOT BASE ANY BUSINESS DECISION UPON
ANY UNDERSTANDING THAT IS INCONSISTENT WITH THE FOREGOING ADMISSION OR CONTRARY
