Re: Revolving Credit Facility

Ladies and Gentlemen:

Bank of America, N.A., acting through its Canada Branch (the “Lender” ) is pleased to make available to TISI Canada Inc., an Ontario corporation (the “Borrower” ), a revolving credit facility on the terms and subject to the conditions set forth below. Terms not defined herein have the meanings assigned to them in Exhibit A hereto.

1. The Facility.

(a) The Commitment. Subject to the terms and conditions set forth herein, the Lender agrees to make available to the Borrower until the Maturity Date a revolving credit facility providing for loans ( “Loans” ) in an aggregate principal amount not exceeding at any time $7,500,000 (the “Commitment” ). Within the foregoing limit, the Borrower may borrow, repay and reborrow Loans until the Maturity Date.

(b) Borrowings, Conversions, Continuations. The Borrower may request that Loans be (i) made as or converted to Prime Rate Loans by irrevocable notice to be received by the Lender not later than 10 a.m. on the Business Day of the borrowing or conversion, or (ii) made or continued as, or converted to, LIBOR Loans by irrevocable notice to be received by the Lender not later than 10 a.m. three Business Days prior to the Business Day of the borrowing, continuation or conversion. If the Borrower fails to give a notice of conversion or continuation prior to the end of any Interest Period in respect of any LIBOR Loan, the Borrower shall be deemed to have requested that such Loan be converted to a Prime Rate Loan on the last day of the applicable Interest Period. If the Borrower requests that a Loan be continued as or converted to a LIBOR Loan, but fails to specify an Interest Period with respect thereto, the Borrower shall be deemed to have selected an Interest Period of one month. Notices pursuant to this Paragraph 1(b) may be given by telephone if promptly confirmed in writing.

Each LIBOR Loan shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof. Each Prime Rate Loan shall be in a minimum principal amount of $100,000. There shall not be more than three different Interest Periods in effect at any time.

(c) Interest. Each Loan shall bear interest at a rate per annum equal to (i) in the case of a LIBOR Loan, the LIBO Rate plus the Applicable Rate for LIBOR Loans; or (ii) in the case of a Prime Rate Loan, the Prime Rate plus the Applicable Rate for Prime Rate Loans. Interest on Prime Rate Loans shall be calculated on the basis of a year of 365 or 366 days and actual days elapsed. All other interest hereunder shall be calculated on the basis of a year of 360 days and actual days elapsed.

The Borrower promises to pay interest (i) for each LIBOR Loan, (A) on the last day of the applicable Interest Period, and, if the Interest Period is longer than three months, on the respective dates that fall every three months after the beginning of the Interest Period, and (B) on the date of any conversion of such Loan to a Prime Rate Loan; (ii) for Prime Rate Loans, on the last Business Day of each calendar quarter; and (iii) for all Loans, on the Maturity Date. If the time for any payment is extended by operation of law or otherwise, interest shall continue to accrue for such extended period.

After the date any principal amount of any Loan is due and payable (whether on the Maturity Date, upon acceleration or otherwise), or after any other monetary obligation hereunder shall have become due and payable (in each case without regard to any applicable grace periods), the Borrower shall pay, but only to the extent permitted by law, interest (after as well as before judgment) on such amounts at a rate per annum equal to the Prime Rate plus 2.75%. Furthermore, while any Event of Default exists, the Borrower shall pay interest on the principal amount of the Loans at a rate per annum equal to the Prime Rate plus 2.75%. Accrued and unpaid interest on past due amounts shall be payable on demand.

In no case shall interest hereunder exceed the amount that the Lender may charge or collect under applicable law.

(d) Evidence of Loans. The Loans and all payments thereon shall be evidenced by the Lender’s loan accounts and records; provided, however, that upon the request of the Lender, the Loans may be evidenced by a promissory note in the form of Exhibit B hereto in addition to such loan accounts and records. Such loan accounts, records and promissory note shall be conclusive absent manifest error of the amount of the Loans and payments thereon. Any failure to record any Loan or payment thereon or any error in doing so shall not limit or otherwise affect the obligation of the Borrower to pay any amount owing with respect to the Loans.

(e) Repayment. The Borrower may, upon three Business Days’ notice, in the case of LIBOR Loans, and upon same-day notice in the case of Prime Rate Loans, repay Loans on any Business Day; provided that the Borrower pays all Breakage Costs (if any) associated with such repayment on the date of such repayment. Repayments of LIBOR Loans must be accompanied by a payment of interest on the amount so prepaid. Repayments of LIBOR Loans must be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof. Repayments of Prime Rate Loans must be in a principal amount of $100,000 or, if less, the entire principal amount thereof then outstanding. In any event, the Borrower promises to repay the principal amount of all Loans, and to pay all accrued and unpaid interest thereon and all other amounts payable by the Borrower hereunder, outstanding on the Maturity Date.

The Borrower shall make all payments required hereunder not later than 1:00 p.m. on the date of payment in same day funds in Dollars at the office of the Lender located at 200 Front Street West, Toronto, Ontario or such other address as the Lender may from time to time designate in writing.

All payments by the Borrower to the Lender hereunder shall be made to the Lender in full without set-off or counterclaim and free and clear of and exempt from, and without deduction or withholding for or on account of, any present or future taxes, levies, imposts, duties or charges of whatsoever nature imposed by any government or any political subdivision or taxing authority thereof. The Borrower shall reimburse the Lender for any taxes imposed on or withheld from such payments (other than taxes imposed on the Lender’s income, and franchise taxes imposed on the Lender, by the jurisdiction under the laws of which the Lender is organized or any political subdivision thereof).

Page 10

The Lender shall be entitled to reasonably rely and act upon any notices (including telephonic notices of borrowings, conversions and continuations) purportedly given by or on behalf of the Borrower even if (i) such notices were not made in a manner specified herein, were incomplete or were not preceded or followed by any other form of notice specified herein, or (ii) the terms thereof, as understood by the recipient, varied from any confirmation thereof.

The Borrower agrees to execute any documents reasonably requested by the Lender in connection with any such assignment. All information provided by or on behalf of the Borrower to the Lender or its affiliates may be furnished by the Lender to its affiliates and to any actual or proposed assignee or participant.

(i) The Borrower shall indemnify and hold harmless the Lender, its affiliates, and their respective partners, directors, officers, employees, agents and advisors (collectively the “Indemnitees” ) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses (including the fees, charges and disbursements of any counsel for any Indemnitee), incurred by any Indemnitee or asserted against any Indemnitee by any third party or by the Borrower arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or thereunder, or the consummation of the transactions contemplated hereby or thereby, (ii) any Loan or the use or proposed use of the proceeds therefrom, (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Borrower or any Subsidiary, or any Environmental Liability related in any way to the Borrower or any Subsidiary, or (iv) any actual or prospective claim, litigation,

Page 11

investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by the Borrower, and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or (y) result from a claim brought by the Borrower against the Lender for breach in bad faith of the Lender’s obligations hereunder or under any other Loan Document, if the Borrower has obtained a final and nonappealable judgment in its favor on such claim as determined by a court of competent jurisdiction. To the fullest extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan or the use of the proceeds thereof. No Indemnitee shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby. The agreements in this Paragraph 6(i) shall survive the termination of the Commitment and the repayment, satisfaction or discharge of all the other obligations and liabilities of the Borrower under the Loan Documents. All amounts due under this Paragraph 6(i) shall be payable within ten Business Days after demand therefor.

(j) If any provision of this Agreement or the other Loan Documents is held to be illegal, invalid or unenforceable, (i) the legality, validity and enforceability of the remaining provisions of this Agreement and the other Loan Documents shall not be affected or impaired thereby and (ii) the parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

(k) This Agreement may be executed in one or more counterparts, and each counterpart, when so executed, shall be deemed an original but all such counterparts shall constitute but one and the same instrument.

(l) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ARE GOVERNED BY, AND SHALL BE CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE PROVINCE OF ONTARIO AND THE FEDERAL LAWS OF CANADA APPLICABLE THEREIN. THE BORROWER HEREBY IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF THE

Page 12

COURTS OF THE PROVINCE OF ONTARIO, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO ANY OF THE LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY, OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT. THE BORROWER IRREVOCABLY CONSENTS TO THE SERVICE OF ANY AND ALL PROCESS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES OF SUCH PROCESS TO THE BORROWER AT ITS ADDRESS SET FORTH BENEATH ITS SIGNATURE HERETO. THE BORROWER IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

(m) Notwithstanding any provisions of this Agreement, the Borrower shall in no event be obliged to make any payments of interest or other amounts payable to the Lender hereunder in excess of an amount or rate which would be prohibited by law or would result in the receipt by the Lender of interest at a criminal rate (as such terms are construed under the Criminal Code (Canada)).

(n) For the purposes of this Agreement, whenever any interest is calculated on the basis of a period of time other than a calendar year, the annual rate of interest to which each rate of interest determined pursuant to such calculation is equivalent for the purposes of the Interest Act (Canada) is such rate as so determined multiplied by the actual number of days in the calendar year in which the same is to be ascertained and divided by the number of days used in the basis of such determination.

(o) The parties acknowledge and agree that all calculations of interest under the Loan Documents are to be made on the basis of the nominal interest rate described herein and not on the basis of effective yearly rates or on any other basis which gives effect to the principle of deemed reinvestment of interest. The parties acknowledge that there is a material difference between the stated nominal interest rates and the effective yearly rates of interest and that they are capable of making the calculations required to determine such effective yearly rates of interest.

(p) The Lender hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub.L. 107-56 (signed into law October 26, 2001)) (the “Act” ), the Lender is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow the Lender to identify the Borrower in accordance with the Act.

(q) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

FORM OF PROMISSORY NOTE

Cdn. $7,500,000                         ,             

FOR VALUE RECEIVED, the undersigned, TISI CANADA INC., an Ontario corporation (the “Borrower” ), hereby promises to pay to the order of BANK OF AMERICA, N.A., acting through its Canada Branch (the “Lender” ), at the offices of the Lender situated in Toronto, Ontario, the principal sum of SEVEN MILLION FIVE HUNDRED THOUSAND Dollars ($7,500,000) or, if less, the aggregate unpaid principal amount of all Loans made by the Lender to the Borrower pursuant to the letter agreement, dated as of even date herewith (such letter agreement, as it may be amended, restated, extended, supplemented or otherwise modified from time to time, being hereinafter called the “Agreement‘ ), between the Borrower and the Lender, on the Maturity Date. The Borrower further promises to pay interest on the unpaid principal amount of the Loans evidenced hereby from time to time at the rates, on the dates, and otherwise as provided in the Agreement.

The loan account records maintained by the Lender shall at all times be conclusive evidence, absent manifest error, as to the amount of the Loans and payments thereon; provided, however, that any failure to record any Loan or payment thereon or any error in doing so shall not limit or otherwise affect the obligation of the Borrower to pay any amount owing with respect to the Loans.

This promissory note is the promissory note referred to in, and is entitled to the benefits of, the Agreement, which Agreement, among other things, contains provisions for acceleration of the maturity of the Loans evidenced hereby upon the happening of certain stated events and also for prepayments on account of principal of the Loans prior to the maturity thereof upon the terms and conditions therein specified.

For the purposes of this promissory note, whenever any interest is calculated on the basis of a period of time other than a calendar year, the annual rate of interest to which each rate of interest determined pursuant to such calculation is equivalent for the purposes of the Interest Act (Canada) is such rate as so determined multiplied by the actual number of days in the calendar year in which the same is to be ascertained and divided by the number of days used in the basis of such determination.

Unless otherwise defined herein, terms defined in the Agreement are used herein with their defined meanings therein. This promissory note shall be governed by, and construed in accordance with, the laws of Ontario and the federal laws of Canada applicable therein.
