     3.5 Activation Date. Subject to the terms and conditions hereof, on the
Closing Date MLPF&S activated a WCMA Line of Credit for WCMA Reducing Revolving
Loans for Customer in the amount of the Maximum WCMA Reducing Revolving Line of
Credit. The WCMA Reducing Revolving Loan will be funded out of the WCMA Line of
Credit for WCMA Reducing Revolving Loans immediately after such activation (or, if
otherwise directed in the Closing Certificate and hereafter expressly agreed by
MLBFS, all or part of the WCMA Reducing Revolving Loan may be made available as a
WCMA Line of Credit and funded by Customer).




     3.6 Subsequent WCMA Loans. Subject to the terms and conditions hereof, during
the period from and after the Closing Date to the Maturity Date: (a) subject to
Section 3.12, Customer may repay the outstanding principal amount of the WCMA
Reducing Revolving Loans in whole or in part at any time without premium or penalty,
and request a re-borrowing of amounts repaid on a revolving basis, and (b) in
addition to WCMA Reducing Revolving Loans made automatically to pay accrued
interest, as hereafter provided, MLBFS will make such WCMA Reducing Revolving Loans
as Customer may from time to time request or be deemed to have requested in
accordance with the terms hereof. Customer may request WCMA Reducing Revolving
Loans by use of WCMA Checks, FTS, Visa® charges, wire transfers, or such other means
of access to the WCMA Line of Credit for WCMA Reducing Revolving Loans as may be
permitted by MLBFS from time to time; it being understood that so long as the WCMA
Line of Credit for WCMA Reducing Revolving Loans shall be in effect, any charge or
debit to the WCMA Account for WCMA Reducing Revolving Loans that but for the WCMA
Line of Credit for WCMA Reducing Revolving Loans would under the terms of the WCMA
Agreement for WCMA Reducing Revolving Loans result in an overdraft, shall be deemed
a request by Customer for a WCMA Reducing Revolving Loan.




     3.7 Conditions of Subsequent WCMA Reducing Revolving Loans. Notwithstanding
the foregoing, MLBFS shall not be obligated to make any WCMA Reducing Revolving
Loan, and may without notice refuse to honor any such request by Customer, if at the
time of receipt by MLBFS of Customer’s request: (a) giving effect to the WCMA
Reducing Revolving Loan would cause the aggregate outstanding principal amount of
the WCMA Reducing Revolving Loan to exceed the Maximum WCMA Reducing Revolving Line
of Credit; or (b) the Maturity Date shall have occurred or the WCMA Reducing
Revolving Loan shall have otherwise been terminated in accordance with the terms
hereof; (c) Stratagene shall not have delivered the most recently required Borrowing
Base Certificate (as defined in and pursuant to Section 7.2(a)(iv);or (d) an event
shall have occurred and be continuing which shall have caused any of the General
Funding Conditions to not then be met or satisfied to the reasonable satisfaction of
MLBFS. The making by MLBFS of any WCMA Reducing Revolving Loan (including, without
limitation, the making of a WCMA Reducing Revolving Loan to pay accrued interest or
late charges, as hereafter provided) at a time when any one or more of said
conditions shall not have been met shall not in any event be



4









 







construed as a waiver of said condition or conditions or of any Default, and
shall not prevent MLBFS at any time thereafter while any condition shall not have
been met from refusing to honor any request by Customer for a WCMA Reducing
Revolving Loan.




     3.8 WCMA Reducing Revolving Note. Customer hereby unconditionally promises to
pay to the order of MLBFS, at the times and in the manner set forth in this Loan
Agreement, or in such other manner and at such place as MLBFS may hereafter
designate in writing: (a) the outstanding principal amount of all WCMA Reducing
Revolving Loans; (b) interest at the Applicable Interest Rate on the outstanding
principal amount of all WCMA Reducing Revolving Loans (computed for the actual
number of days elapsed on the basis of a year consisting of 360 days), from and
including the date on which each WCMA Reducing Revolving Loan is made until the date
of payment of all WCMA Reducing Revolving Loans in full; and (c) on demand, all
other sums payable pursuant to this Loan Agreement with respect to WCMA Reducing
Revolving Loans, including, but not limited to, any late charges. Except as
otherwise expressly set forth herein, Customer hereby waives presentment, demand for
payment, protest and notice of protest, notice of dishonor, notice of acceleration,
notice of intent to accelerate and all other notices and formalities in connection
with the WCMA Reducing Revolving Loans and this Loan Agreement.




     3.9 Interest. (a) An amount equal to accrued interest on the daily
outstanding principal amount of the WCMA Reducing Revolving Loans shall be payable
by Customer monthly on each Interest Due Date, commencing with the first Interest
Due Date after the Closing Date shall occur. Unless otherwise hereafter directed in
writing by MLBFS on or after the Maturity Date, such interest will be automatically
charged to the WCMA Account for WCMA Reducing Revolving Loans on the applicable
Interest Due Date, and, to the extent not paid with free credit balances or the
proceeds of sales of any Money Accounts then in the WCMA Account for WCMA Reducing
Revolving Loans, as hereafter provided, such interest will be paid by a WCMA
Reducing Revolving Loan, to the extent of availability, and added to the outstanding
principal amount of WCMA Reducing Revolving Loans. All interest shall be computed
for the actual number of days elapsed on the basis of a year consisting of 360 days.




     (b) Upon the occurrence and during the continuance of any Event of Default, but
without limiting the rights and remedies otherwise available to MLBFS hereunder or
waiving such Event of Default, the interest payable by Customer hereunder shall at
the option of MLBFS accrue and be payable at the Default Rate. The Default Rate,
once implemented, shall continue to apply to the Obligations under this Loan
Agreement and be payable by Customer until the date such Event of Default has been
cured to the reasonable satisfaction of MLBFS.




     (c) Notwithstanding any provision to the contrary in any of the Loan Documents,
no provision of the Loan Documents shall require the payment or



5









 







permit the collection of Excess Interest. If any Excess Interest is provided
for, or is adjudicated as being provided for, in the Loan Documents, then: (i)
Customer shall not be obligated to pay any Excess Interest; and (ii) any Excess
Interest that MLBFS may have received pursuant to this Article III or under any of
the Loan Documents shall, at the option of MLBFS, be either applied as a credit
against the then unpaid principal amount of WCMA Reducing Revolving Loans, or
refunded to the payor thereof




     3.10 Repayment. Unless the WCMA Line of Credit for WCMA Reducing Revolving
Loans shall have been earlier terminated pursuant to the terms hereof, on the last
Business Day of January, 2008, the WCMA Line of Credit for WCMA Reducing Revolving
Loans shall, without further action of either of the parties hereto, be terminated,
Customer shall pay to MLBFS the outstanding principal amount of all outstanding WCMA
Reducing Revolving Loans, if any, together with all accrued and unpaid interest
thereon, and the WCMA Account for WCMA Reducing Revolving Loans, at the option of
Customer, will either be converted to a WCMA Cash Balance (subject to any
requirements of MLPF&S) or terminated.




     3.11 Mandatory Payments. CUSTOMER AGREES THAT IT WILL, WITHOUT DEMAND,
INVOICING OR THE REQUEST OF MLBFS, FROM TIME TO TIME MAKE SUFFICIENT PAYMENTS ON
ACCOUNT OF THE WCMA REDUCING REVOLVING LOAN BALANCE TO ASSURE THAT THE SUM OF THE
WCMA REDUCING REVOLVING LOAN BALANCE WILL NOT AT ANY TIME EXCEED THE MAXIMUM WCMA
REDUCING REVOLVING LINE OF CREDIT.”
