                                                             Line of Credit Note

                                                                   $5,000,000.00
Due: May 31, 2004                                             Date: May 30, 2003

Promise to Pay. On or before May 31, 2004, for value received, Alltech
Associates, Inc. (the "Borrower") promises to pay to Bank One, NA, with its main
office in Chicago, IL, whose address is 1 Bank One Plaza, Chicago, IL 60670 (the
"Bank") or order, in lawful money of the United States of America, the sum of
Five Million and 00/100 Dollars ($5,000,000.00) or such lesser sum as is
indicated on Bank records, plus interest computed on the basis of the actual
number of days elapsed in a year of 360 days at the rate of 0% per annum above
the Prime Rate (the "Note Rate"), and at the rate of 3.00% per annum above the
Note Rate, at the Bank's option, upon the occurrence of any default under this
Note, whether or not the Bank elects to accelerate the maturity of this Note,
from the date such increased rate is imposed by the Bank. In this Note, "Prime
Rate" means a rate per annum equal to the prime rate of interest announced from
time to time by the Bank or its parent (which rate is not necessarily the lowest
rate charged to any customer), changing when and as the prime rate changes.

In no event shall the interest rate exceed the maximum rate allowed by law. Any
interest payment that would for any reason be unlawful under applicable law
shall be applied to principal.

Interest will be computed on unpaid principal balance from the date of each
borrowing.

Until maturity, the Borrower will pay consecutive monthly installments of
interest only commencing June 30, 2003.

The Borrower will pay, without setoff, deduction, or counterclaim, the Bank at
the Bank's address above or at such other place as the Bank may designate in
writing. If any payment of principal or interest on this Note shall become due
on a day that is not a Business Day, the payment will be made on the next
succeeding Business Day. The term "Business Day" in this Note means a day other
than a Saturday, Sunday or any other day on which national banking associations
are authorized to be closed. Payments shall be allocated among principal,
interest and fees at the discretion of the Bank unless otherwise agreed or
required by applicable law. Acceptance by the Bank of any payment that is less
than the payment due at that time shall not constitute a waiver of the Bank's
right to receive payment in full at that time or any other time.

Late Fee. If any payment is not received by the Bank within ten (10) days after
its due date, the Bank may assess and the Borrower agrees to pay a late fee
equal to the greater of: (a) five percent (5.00%) of the past due amount or (b)
Twenty Five and 00/100 Dollars ($25.00), up to the maximum amount of One
Thousand Five Hundred and 00/100 Dollars ($1,500.00) per late charge.

Business Loan. The Borrower acknowledges and agrees that this Note evidences a
loan for a business, commercial, agricultural or similar commercial enterprise
purpose, and that all advances made under this Note shall not be used for any
personal, family or household purpose.

Credit Facility. The Bank has approved a credit facility to the Borrower in a
principal amount not to exceed the face amount of this Note. The credit facility
is in the form of advances made from time to time by the Bank to the Borrower.
This Note evidences the Borrower's obligation to repay those advances. The
aggregate principal amount of debt evidenced by this Note is the amount
reflected from time to time in the records of the Bank. Until the earliest of
maturity, the occurrence of any default, or the occurrence of any event that
would constitute the occurrence of any default but for the lapse of time until
the end of any grace or cure period, the borrower may borrow, pay down and
reborrow under this Note subject to the terms of the Related Documents.

Liabilities. The term "Liabilities" in this Note means all obligations,
indebtedness and liabilities of the Borrower to any one or more of the Bank,
BANK ONE CORPORATION, and any of their subsidiaries, affiliates or successors,
now existing or later arising, including, without limitation, all loans,
advances, interest, costs, overdraft indebtedness, credit card indebtedness,
lease obligations, or obligations relating to any Rate Management Transaction,
all monetary obligations incurred or accrued during the pendency of any
bankruptcy, insolvency, receivership or other similar proceedings, regardless of
whether allowed or allowable in such proceeding, and all renewals, extensions,
modifications, consolidations or substitutions of any of the foregoing, whether
the Borrower may be liable jointly with others or individually liable as a
debtor, maker, co-maker, drawer, endorser, guarantor, surety or otherwise, and
whether a voluntarily or involuntarily incurred, due or not due, absolute or
contingent, direct or indirect, liquidated or unliquidated. The term "Rate
Management Transaction" in this Note means any transaction (including an
agreement with respect thereto) now existing or thereafter entered into among

affiliates or their successors, which is a rate swap, basis swap, forward rate
transaction, commodity swap, commodity option, equity or equity index swap,

exchange transaction, cap transaction, floor transaction, collar transaction,

transactions) or any combination thereof, whether linked to one or more interest
rates, foreign currencies, commodity prices, equity prices or other financial
measures.

Related Documents. The term "Related Documents" in this Note means all loan
agreements, credit agreements, reimbursement agreements, security agreements,
mortgages, deeds of trust, pledge agreements, assignments, guaranties, or any
other instrument or document executed in connection with this Note or in
connection with any of the Liabilities.

Security. The term "Collateral" in this Note means all real or personal property
described in all security agreements, pledge agreements, mortgages, deeds of
trust, assignments, or other instruments now or hereafter executed in connection
with this Note or in connection with any of the Liabilities. If applicable, the
Collateral secures the payment of this Note and the Liabilities.

Bank's Right of Setoff. In addition to the Collateral, if any, the Borrower
grants to the Bank a security interest in, and the Bank is authorized to setoff
and apply, all Accounts, Securities and Other Property, and Bank Debt against
any and all Liabilities of the Borrower. This right of setoff may be exercised
at any time and from time to time, and without prior notice to the Borrower.
This security interest and right of setoff may be enforced or exercised by the
Bank regardless of whether or not the Bank has made any demand under this
paragraph or whether the Liabilities are contingent, matured, or unmatured. Any
delay, neglect or conduct by the Bank in exercising its rights under this
paragraph will not be a waiver of the right to exercise this right of setoff or
enforce this security interest. The rights of the Bank under this paragraph are
in addition to other rights the Bank may have in the Related Documents or by
law. In this paragraph: (a) the term "Accounts" means any and all accounts and
deposits of the Borrower (whether general, special, time, demand, provisional or
final) at any time held by the Bank (including all Accounts held jointly with
another, but excluding any IRA or Keogh Account, or any trust Account in which a
security interest would be prohibited by law); (b) the term "Securities and
Other Property" means any and all securities and other property of the Borrower
in the custody, possession or control of the Bank (other than property held by
the Bank in a fiduciary capacity); and (c) the term "Bank Debt" means all
indebtedness at any time owing by the Bank, to or for the credit or account of
the Borrower.

its terms; and (c) all balance sheets, profit and loss statements, and other

covered by this Note.

a trustee, receiver or any other entity, whether under any bankruptcy act or
otherwise any such payment is hereinafter referred to as a "Preferential
Payment"), then this Note shall continue to be effective or shall be

intended to be satisfied by such Preferential Payment shall be revived and
continued in full force and effect as if said Preferential Payment had not been
