1.3 Paragraph 2.3(a) is amended to read in its entirety as follows:

(a) The Borrower will pay interest on any BSBY Daily Floating Rate Loan on the first banking day of each month until payment in full of all principal outstanding under this facility. The Borrower will pay interest on any BSBY Rate Loan at the end of the applicable interest period; provided that no interest period shall expire later than the Loan Maturity Date for the applicable Loan. The amount of each interest payment shall be the amount of accrued interest on the Uncommitted Line of Credit as of the interest payment date or such earlier accrual date as indicated on the billing statement for such interest payment.

1.4 In Paragraph 2.4(a) the words “LIBOR Daily Floating Rate Loan” are changed to “BSBY Daily Floating Rate Loan” and the words “LIBOR Rate Loan” are changed to “BSBY Rate Loan”.

1.5 Paragraph 2.4(b) is amended to read in its entirety as follows:

(b) A “BSBY Daily Floating Rate Loan” is a loan that bears interest equal to the BSBY Daily Floating Rate plus 1.15 percentage points The “BSBY Daily Floating Rate” is a fluctuating rate of interest which can change on each banking day. The rate will be adjusted on each banking day to equal the BSBY Screen Rate for U.S. Dollar deposits two Business Days prior to the date of determination for a one month term beginning on that date; provided that if such rate is not published on such determination date then the rate will be the BSBY Screen Rate on the first Business Day immediately prior thereto. “BSBY Screen Rate” means the Bloomberg Short-Term Bank Yield Index rate (“BSBY”) administered by Bloomberg Index Services Limited and published on the applicable Reuters screen page (or such other commercially available source providing such quotations as may be designated by the Bank from time to time). If such rate is not available at such time for any reason or the Bank makes the determination to incorporate or adopt a new interest rate to replace the BSBY Daily Floating Rate in credit agreements, then the Bank may replace the BSBY Daily Floating Rate with an alternate interest rate and adjustment, if applicable, as reasonably selected by the Bank, giving due consideration to any evolving or then existing conventions for such interest rate and adjustment (any such successor interest rate, as adjusted, the “Successor Rate”). In connection with the implementation of the Successor Rate, the Bank will have the right, from time to time, in good faith to make any conforming, technical, administrative or operational changes to this Agreement as may be appropriate to reflect the adoption and administration thereof and, notwithstanding anything to the contrary herein or in any other loan document, any amendments to this Agreement implementing such conforming changes will become effective upon notice to the Borrower without any further action or consent of the other parties hereto. A “Business Day” is a day other than a Saturday or a Sunday on which banks are open for business in the State of New York. If at any time the BSBY Daily Floating Rate or any Successor Rate is less than zero, such rate shall be deemed to be zero for the purposes of this Agreement.

1.6 Paragraph 2.4(c) is amended to read in its entirety as follows:

(c) A “BSBY Rate Loan” is a Loan that bears interest equal to the BSBY Rate plus 1.15 percentage points. No more than ten (10) BSBY Rate Loans may be outstanding at any one time. The “BSBY Rate” means, for any applicable interest period, the rate per annum equal to the BSBY Screen Rate two Business Days prior to the commencement of such interest period with a term equivalent to such interest period; provided that if such rate is not published on such determination date then the rate will be the BSBY Screen Rate on the first Business Day immediately prior thereto. “BSBY Screen Rate” means the Bloomberg Short-Term Bank Yield Index rate (“BSBY”) administered by Bloomberg Index Services Limited and published on the applicable Reuters screen page (or such other commercially available source providing such quotations as may be designated by the Bank from time to time). If the BSBY Rate is not available at such time for any reason or the Bank makes the determination to incorporate or adopt a new interest rate to replace the BSBY Rate in credit agreements, then the Bank may replace the BSBY Rate with an alternate interest rate and adjustment, if applicable, as reasonably selected by the Bank, giving due consideration to any evolving or then existing conventions for such interest rate and adjustment (any such successor interest rate, as adjusted, the “Successor Rate”). In connection with the implementation of the Successor Rate, the Bank will have the right, from time to time, in good faith to make any conforming, technical, administrative or operational changes to this Agreement as may be appropriate to reflect the adoption and administration thereof and, notwithstanding anything to the contrary herein or in any other loan document, any amendments to this Agreement implementing such conforming changes will become effective upon notice to the Borrower without any further action or consent of the other parties hereto. If at any time the BSBY Rate or any Successor Rate is less than zero, such rate shall be deemed to be zero for purposes of this Agreement.

1.7 Paragraph 2.4(d) is amended to read in its entirety as follows:

(d) The election of BSBY Rates shall be subject to the following terms and requirements: The interest period during which the BSBY Rate will be in effect will be one (1) or three (3) months, as agreed to by the Bank in its sole and absolute discretion. The first day of the interest period must be a day other than a Saturday or a Sunday on which banks are open for business in New York (a “BSBY Banking Day”). The last day of the interest period and the actual number of days during the interest period will be determined by the Bank using the practices of the inter-bank market (as determined by the Bank in its sole and absolute discretion). The Borrower shall irrevocably request a BSBY Rate Loan no later than 12:00 noon Eastern time on the BSBY Banking Day preceding the day on which the BSBY Rate will be set, as specified above. For example, if there are no intervening holidays or weekend days in any of the relevant locations, the request must be made at least two days before the BSBY Rate takes effect. Each prepayment of a BSBY Rate Loan, whether voluntary, upon the Bank’s demand, by reason of acceleration, maturity or otherwise, will be accompanied by the amount of accrued interest on the amount prepaid and a prepayment fee as described below. A “prepayment” is a payment of an amount on a date earlier than the scheduled payment date for such amount as required by this Agreement. The prepayment fee shall be in an amount sufficient to compensate the Bank for any loss, cost or expense incurred by it as a result of the prepayment, including any loss of anticipated profits and any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such BSBY Rate Loan or from fees payable to terminate the deposits from which such funds were obtained. The Borrower shall also pay any customary administrative fees charged by the Bank in connection with the foregoing.

1.8 The following Paragraph 2.4(e) is added as follows:

(e) If the BSBY Rate and the BSBY Daily Floating Rate (each a “Rate”) is not available at such time for any reason or the Bank makes the determination to incorporate or adopt a new interest rate to replace a Rate in credit agreements, then the Bank may replace such Rate with an alternate interest rate and adjustment, if applicable, as reasonably selected by the Bank, giving due consideration to any evolving or then existing conventions for such interest rate and adjustment (any such successor interest rate, as adjusted, the “Successor Rate”). In connection with the implementation of any Successor Rate, the Bank will have the right, from time to time, in good faith to make any conforming, technical, administrative or operational changes to this Agreement as may be appropriate to reflect the adoption and administration thereof and, notwithstanding anything to the contrary herein or in any other loan document, any amendments to this Agreement implementing such conforming changes will become effective upon notice to the Borrower without any further action or consent of the other parties hereto. If at any time any Successor Rate is less than zero, such rate shall be deemed to be zero for the purposes of this Agreement.

1.9 Amendment to definition of Borrower. The term “Borrower” in the Agreement is hereby amended to mean the “Borrower” as defined in this Amendment the effect of which change is that Tidewater Environmental Services, Inc. is no longer a party to the Agreement as hereby amended.
