EXHIBIT 10.31 TERM PROMISSORY NOTE WITH AGREEMENT (this "Note") U.S. $1,119,309.01 February 29, 1996 ("Date") ON OR BEFORE February 5, 2000 ("Stated Maturity") FOR VALUE RECEIVED, WASTE RECOVERY, INC. ("Borrower"), a Texas corporation, promises to pay to the order of TEXAS COMMERCE BANK NATIONAL ASSOCIATION ("Bank") at its banking house at 2200 Ross Avenue, P.O. Box 660197, Dallas County, Dallas, TX 75266-0197, or at such other location as Bank may designate, in immediately available funds and in lawful money of the United States of America, the sum of ONE MILLION ONE HUNDRED NINETEEN THOUSAND THREE HUNDRED NINE AND ONE/100THS UNITED STATES DOLLARS (U.S. $1,119,309.01) or the aggregate unpaid amount of all advances hereunder ("Loan"), whichever is the lesser amount, together with interest on the said principal or so much thereof as may from time to time be advanced and outstanding hereunder computed from the date of each advance until the maturity of this Note (howsoever brought about) at a variable rate per annum equal to the Stated Rate (as defined hereinafter) as it exists from time to time; provided however, in no event shall interest hereon ever be charged, paid, collected or received at a rate in excess of the maximum nonusurious rate of interest from time to time permitted by applicable federal or Texas law, whichever shall permit the higher lawful interest rate (the "Highest Lawful Rate"). To the extent Texas law shall be controlling to determine the Highest Lawful Rate, Bank and any subsequent owner or holder hereof has elected the "indicated" ceiling as defined and described in the Texas Credit Code V.T.C.S. Article 5069-1.04 or as same may be hereafter amended, and, to the extent other law shall be controlling the Highest Lawful Rate shall be the maximum nonusurious rate of interest allowed by such applicable law. It is expressly agreed that Bank and any subsequent owner or holder hereof may from time to time, as to current and future balances elect and implement any other ceiling under such Article and/or revise the index, formula or provision of law used to compute the rate on this Note by notice to the Borrower, if and to the extent permitted by, and in the manner provided in such Code. If the Stated Rate at any time would exceed the Highest Lawful Rate but for the limitation contained herein, the actual rate of interest to accrue on the unpaid principal amount of this Note shall be limited to the Highest Lawful Rate, but any subsequent reductions in the Stated Rate due to reductions in the Prime Rate shall not reduce the interest rate payable upon the unpaid amount hereof below the Highest Lawful Rate until such time as the total amount of interest accrued on the unpaid principal amount of this Note equals the amount of interest which would have accrued if the Stated Rate had at all times been in effect. The "Stated Rate" shall be the rate per annum determined by reference to the chart immediately following: S&P Rating of Goodyear Stated Rate ---------------------- ----------- AAA, AA+, or AA Prime Rate minus 1.00% AA-, A+, or A Prime Rate minus 0.50% A-, BBB+, BBB, or BBB- Prime Rate BB+ or lower Prime Rate plus 1.00% "Prime Rate" shall mean that rate as determined from time to time by Bank as being its prime rate, and thereafter entered in the minutes of the Bank's Loan and Discount Committee. Without notice to the Borrower or any other person, the Prime Rate shall change automatically from time to time as and in the amount by which said prime rate shall fluctuate, with each such change to be effective as of the date of each change in such prime rate. THE PRIME RATE IS A REFERENCE RATE AND DOES NOT NECESSARILY REPRESENT THE LOWEST OR BEST RATE ACTUALLY CHARGED TO ANY 1 CUSTOMER. BANK MAY MAKE COMMERCIAL LOANS OR OTHER LOANS AT RATES OF INTEREST AT, ABOVE OR BELOW THE PRIME RATE. The "S&P Rating of Goodyear" shall refer to the rating of the long term debt of Goodyear Tire & Rubber Company ("Goodyear") as published from time to time by Standard & Poor's, Inc. ("S&P"). Adjustments to the Stated Rate on the basis of changes in the S&P Rating of Goodyear shall become effective, without notice to Borrower, on the date that such change has been officially published by S&P as reasonably determined by Bank. Borrower understands and agrees that Bank's loan payment advices (which are subject in all respects to the agreements defining Borrower's obligations in this Note) may, from time to time, include delayed advice of changes in interest payable hereunder reflecting the lag time inherent in obtaining knowledge of Goodyear rating changes and reflecting such changes in Bank's records concerning this Note. Time is of the essence. Principal payments each in the amount of $10,000.00 shall be due and payable monthly, together with accrued and unpaid interest, beginning March 29, 1996 and continuing on the 29th day of each month thereafter, and at the Stated Maturity when all outstanding principal and accrued and unpaid interest and all other amounts owing hereunder shall be finally due and payable. Interest will be calculated on the basis of a 360 day year for the actual number of days elapsed unless such calculation would result in a usurious interest rate, in which case such interest shall be calculated on the basis of a 365 or 366 day year, as the case may be. All past due principal and, to the extent permitted by applicable law, interest on this Note shall bear interest at the Highest Lawful Rate, or if applicable law shall not provide for a maximum nonusurious rate of interest, at a rate per annum equal to the Prime Rate plus five percent (5%) per annum. In addition to all principal and accrued interest on this Note, the Borrower agrees to pay: (a) all reasonable costs and expenses incurred by Bank and all owners and holders of this Note in collecting this Note through probate, reorganization, bankruptcy or any other proceedings; and (b) reasonable attorneys' fees if and when this Note is placed in the hands of an attorney for collection after default. It is the intention of the Borrower and the Bank to conform strictly to the usury laws in force in the state of Texas and in the United States of America, as applicable. It is therefore agreed that: (i) in the event that the maturity hereof is accelerated by reason of an election by the Bank or if the same is prepaid prior to the maturity, all unearned interest shall be canceled automatically or, if theretofore paid, shall either be refunded to the Borrower or credited on the unpaid principal amount of this Note, whichever remedy is chosen by the Bank; (ii) the aggregate of all interest and other charges constituting interest under applicable law and contracted for, chargeable or receivable under this Note or otherwise in connection with this loan transaction shall never produce a rate in excess of the maximum nonusurious rate of interest that the Bank may charge the Borrower under applicable law; and (iii) if any excess interest is contracted for, charged or received, it shall be deemed a mistake and any excessive interest received shall be either refunded to the Borrower or credited on the unpaid principal amount hereof, and this Note and any document which evidences a charging of or contracting for excessive interest shall be automatically deemed reformed so as to permit only the collection of the maximum nonusurious rate and amount of interest; provided, however, that all sums paid or agreed to be paid for the use, forbearance or detention of the loan evidenced hereby shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term of this Note. The unpaid principal balance of this Note at any time shall be the total amounts loaned or advanced by the owner or holder hereof, less the amount of all payments or prepayments of principal made hereon by or for the Borrower. Absent manifest error the records of Bank or any subsequent owner or holder hereof shall be conclusive as to amounts owed, both principal and interest, hereunder. All payments and prepayments hereon may, at Bank's or any subsequent owner's or holder's sole option, be applied to accrued interest, to 2 principal, or to both. The term "Loan Documents" shall refer to each and all of this Note and all such other agreements, documents, instruments, applications, statements, and other writings required by Bank and executed and delivered to Bank by Borrower in connection with or in any way related to the Loan or this Note. The purpose of the Loan is to refinance Borrower's indebtedness with another financial institution. A.
