                                 WITNESSETH:
                                 -----------

         WHEREAS, Borrower, the Banks and the Agent are parties to that
certain Loan Agreement dated as of November 30, 2000 (the "Loan Agreement;"
all capitalized terms used and not otherwise defined in this Amendment shall
have the respective meanings ascribed to them in the Loan Agreement as
amended by this Amendment); and

         WHEREAS, Borrower, the Banks and the Agent desire to amend the Loan
Agreement in the manner hereinafter set forth to, among other things, (a)
extend the Revolving Credit Period, (b) reduce the aggregate of the
Revolving Credit Commitments to $135,000,000.00, (c) increase the Revolving

         NOW, THEREFORE, in consideration of the premises and for other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, Borrower, the Banks and the Agent hereby agree as follows:

         1.       Pursuant to the terms of this First Amendment, the
aggregate of the Revolving Credit Commitments of all of the Banks is being
reduced to $135,000,000.00, and in connection with such reduction Bank One,

         2.       The first recital paragraph beginning with the word
"WHEREAS" on the first page of the Loan Agreement is hereby deleted in its
entirety and the following substituted in lieu thereof:

         WHEREAS, Borrower has applied for a revolving credit facility from

<PAGE>
<PAGE>

         "Fed Funds Rate shall mean a rate per annum equal to Thirty-Five
          --------------
Hundredths of One Percent (.35%) over and above the Fed Funds Base Rate,
which Fed Funds Rate shall fluctuate as and when said Fed Funds Base Rate
changes.

         LIBOR Rate shall mean a rate per annum equal to the sum of (a) the
         ----------
quotient of the (i) LIBOR Base Rate divided by (ii) one minus the applicable
LIBOR Reserve Percentage plus (b) Thirty-Five Hundredths of One Percent
                         ----
(.35%) per annum. The LIBOR Rate shall be adjusted automatically on and as
of the effective date of any change in the LIBOR Reserve Percentage.

         Pro Rata Share shall mean for the item at issue, with respect to
         --------------
each Bank, a fraction (expressed as a percentage), the numerator of which is
the portion of such item owned or held by such Bank and the denominator of
which is the total amount of such item owned or held by all of the Banks.
For example, (a) if the amount of the Revolving Credit Commitment of a Bank
is $1,000,000.00 and the total amount of the Revolving Credit Commitments of
all of the Banks is $5,000,000.00, such Bank's Pro Rata Share of the
Revolving Credit Commitments would be Twenty Percent (20%) and (b) if the
original principal amount of a Loan is $5,000,000.00 and the portion of such
Loan made by one Bank is $500,000.00, such Bank's Pro Rata Share of such
Loan would be Ten Percent (10%). As of the date of the First Amendment, the
Pro Rata Shares of the Banks with respect to the Revolving Credit
Commitments and the Loans are as follows: (a) Firstar (now known as U. S.
Bank National Association) - Thirty-Seven and 370,370/10,000,000ths of One
Percent (37.0370370%); (b) The Fuji Bank Limited - Eighteen and
5,185,185/10,000,000ths of One Percent (18.5185185%); (c) Comerica Bank -

Bank Hapoalim B.M. - Twenty-Five and 9,259,259/10,000,000ths of One Percent
(25.9259259%).

         Revolving Credit Commitment shall mean, subject to (a) any

Fuji Bank Limited, $25,000,000.00; (iii) with respect to Comerica Bank,
$25,000,000.00; and (iv) with respect to Bank Hapoalim B.M., $35,000,000.00.

         Revolving Credit Period shall mean the period commencing October 1,
         -----------------------
2001, and ending September 30, 2002."

follows:

and the Banks.

         5.       Section 2.07(b) of the Loan Agreement is hereby deleted in
its entirety and the following substituted in lieu thereof:

         (b) From and including the date of the First Amendment to but
excluding the last day of the Revolving Credit Period, Borrower shall pay to
the Agent for the account of each Bank a nonrefundable facility fee on the
Revolving Credit Commitment of each such Bank calculated by multiplying the
Revolving Credit Commitment of each such Bank by the rate of One-Eighth of
One Percent (1/8%) per annum. Said facility fee shall be (i) calculated on a
daily basis, (ii) payable quarterly in arrears on each March 31, June 30,
September 30 and December 31 during the Revolving

<PAGE>
<PAGE>

Credit Period commencing December 31, 2001, and on the last day of the
Revolving Credit Period, (iii) prorated for any partial quarterly period,
and (iv) calculated on an actual day, 360-day year basis.

For the portion of the fiscal quarter beginning on July 1, 2001 and ending
on the day preceding the date of this First Amendment, Borrower shall pay to
Agent for distribution to the Banks the commitment fee due under Section
2.07(b) of the Loan Agreement as in effect prior to the date of this First
Amendment.

         6.       The Note of Bank Hapoalim B.M. shall be amended and
restated on the date hereof in the form of Exhibit A attached hereto to
                                           ---------

the form of Exhibit A attached hereto.
            ---------

         7.       Borrower hereby agrees to reimburse the Agent upon demand
for all out-of-pocket costs and expenses (including, without limitation,
reasonable attorneys' fees and expenses) incurred by the Agent in the
preparation, negotiation and execution of this Amendment. All of the
obligations of Borrower under this paragraph shall survive the payment of
the Borrower's Obligations and the termination of the Loan Agreement.

         8.       All references in the Loan Agreement to "this Agreement"
and any other references of similar import shall henceforth mean the Loan
Agreement as amended by this Amendment.

         9.       Except to the extent specifically amended by this
Amendment, all of the terms, provisions, conditions, covenants,
representations and warranties contained in the Loan Agreement shall be and
remain in full force and effect and the same are hereby ratified and
confirmed.

         10.      This Amendment shall be binding upon and inure to the
benefit of Borrower, the Banks and the Agent and their respective successors
and assigns, except that Borrower may not assign, transfer or delegate any
of its rights or obligations under the Loan Agreement as amended by this
Amendment.

         11.      Borrower hereby represents and warrants to the Agent and

official or any other Person;

                  (b)      the execution, delivery and performance by

result in any violation of, the terms of the Articles of Incorporation or
Bylaws of Borrower, any applicable law, rule, regulation, order, writ,
judgment or decree of any court or governmental or regulatory body,
instrumentality authority, agency or official or any agreement, document or
instrument to which Borrower is a party or by which Borrower or any of its
Property is bound or to which Borrower or any of its Property is subject;

                  (c)      this Amendment has been duly executed and
delivered by Borrower and constitutes the legal, valid and binding
obligation of Borrower enforceable against Borrower in accordance with its
terms, except as such enforceability may be limited by (i) applicable
bankruptcy, insolvency or similar laws affecting the enforcement of
creditors' rights generally and (ii) general principles of equity
(regardless of whether such enforceability is considered in a proceeding in

<PAGE>
<PAGE>

                  (d)      all of the representations and warranties made by
