SEMITOOL, INC., a Montana corporation (Borrower), organized under the laws of the State of Montana whose chief executive office is located at the address specified after its signature to this Agreement (Borrowers Address) and WELLS FARGO HSBC TRADE BANK, N.A. (Trade Bank), whose address is specified after its signature to this Agreement, have entered into this CREDIT AGREEMENT as of November 1, 2004 (Effective Date). All references to this Agreement include those covenants included in the Addendum to Agreement (Addendum) attached as Exhibit A hereto.

# I. CREDIT FACILITY

1.1 The Facility. Subject to the terms and conditions of this Agreement, Trade Bank will make available to Borrower a Revolving Credit Facility (Facility) for which a Facility Supplement (Supplement) is attached as Exhibit B hereto. Additional terms for the Facility are set forth in the Supplement. The Facility will be available from the Closing Date up to and until March 1, 2006 (Facility Termination Date). Collateral and credit support required for the Facility is set forth in Exhibit C hereto. Definitions for those capitalized terms not otherwise defined are contained in Article 8 below.

1.2 Credit Extension Limit. The aggregate outstanding amount of all Credit Extensions may at no time exceed Fifteen Million Dollars ($15,000,000) (Overall Credit Limit). The aggregate outstanding amount of all Credit Extensions outstanding at any time under Revolving Credit Facility may not exceed that amount specified as the Credit Limit in the Supplement for the Facility. An amount equal to 100% of each unfunded Credit Extension shall be used in calculating the outstanding amount of Credit Extensions under this Agreement.

1.3 Overadvance. All Credit Extensions made hereunder shall be added to and deemed part of the Obligations when made. If, at any time and for any reason, the aggregate outstanding amount of all Credit Extensions made pursuant to this Agreement exceeds the dollar limitation in Section 1.2, then Borrower shall immediately pay to Trade Bank on demand, in cash, the amount of such excess.

1.4 Repayment; Interest and Fees. Each funded Credit Extension shall be repaid by Borrower, and shall bear interest from the date of disbursement at those per annum rates and such interest shall be paid, at the times specified in the Supplement, Note or Facility Document. Borrower agrees to pay to Trade Bank with respect to (a) the Revolving Credit Facility, interest at a per annum rate (i) equal to the Prime Rate as specified in the Note, or (ii) Wells Fargos LIBOR Rate plus 2.25% as specified in the Note, and (b) the Subfacilities, the fees specified in the Supplement as well as those fees specified in the relevant Facility Document(s). Interest and fees will be calculated on the basis of a 360 day year, actual days elapsed. Any overdue payments of principal (and interest to the extent permitted by law) shall bear interest at a per annum floating rate equal
to the Prime Rate plus 5%.

1.5 Prepayments. Credit Extensions under any Facility may only be prepaid in accordance with the terms of the Promissory Note. At the time of any prepayment (including, but not limited to, any prepayment which is a result of the occurrence of an Event of Default and an acceleration of the Obligations) Borrower will pay to Trade Bank all interest accrued on the amount so prepaid to the date of such prepayment and all costs, expenses and fees specified in the Loan Documents.

9.1 Arbitration.

9.2 Governing Rules. Any arbitration proceeding will (i) proceed in a location in California selected by the American Arbitration Association (AAA); (ii) be governed by the Federal Arbitration Act (Title 9 of the United States Code), notwithstanding any conflicting choice of law provision in any of the documents between the parties; and (iii) be conducted by the AAA, or such other administrator as the parties shall mutually agree upon, in accordance with the AAAs commercial dispute resolution procedures, unless the claim or counterclaim is at least $1,000,000.00 exclusive of claimed interest, arbitration fees and costs in which case the arbitration shall be conducted in accordance with the AAAs optional procedures for large, complex commercial disputes (the commercial dispute resolution procedures or the optional procedures for large, complex commercial
disputes to be referred to, as applicable, as the Rules). If there is any inconsistency between the terms hereof and the Rules, the terms and procedures set forth herein shall control. Any party who fails or refuses to submit to arbitration following a demand by any other party shall bear all costs and expenses incurred by such other party in compelling arbitration of any dispute. Nothing contained herein shall be deemed to be a waiver by any party that is a bank of the protections afforded to it under 12 U.S.C. §91 or any similar applicable state law.

9.3 No Waiver of Provisional Remedies, Self-Help and Foreclosure. The arbitration requirement does not limit the right of any party to (i) foreclose against real or personal property collateral; (ii) exercise self-help remedies relating to collateral or proceeds of collateral such as setoff or repossession; or (iii) obtain provisional or ancillary remedies such as replevin, injunctive relief, attachment or the appointment of a receiver, before during or after the pendency of any arbitration proceeding. This exclusion does not constitute a waiver of the right or obligation of any party to submit any dispute to arbitration or reference hereunder, including those arising from the exercise of the actions detailed in sections (i), (ii) and (iii) of this paragraph.

9.4 Arbitrator Qualifications and Powers. Any arbitration proceeding in which the amount in controversy is $5,000,000.00 or less will be decided by a single arbitrator selected according to the Rules, and who shall not render an award of greater than $5,000,000.00. Any dispute in which the amount in controversy exceeds $5,000,000.00 shall be decided by majority vote of a panel of three arbitrators; provided however, that all three arbitrators must actively participate in all hearings and deliberations. The arbitrator will be a neutral attorney licensed in the State of California or a neutral retired judge of the state or federal judiciary of California, in either case with a minimum of ten years experience in the substantive law applicable to the subject matter of the dispute to be arbitrated. The arbitrator will determine whether or not an issue is arbitratable and will give
effect to the statutes of limitation in determining any claim. In any arbitration proceeding the arbitrator will decide (by documents only or with a hearing at the arbitrators discretion) any pre-hearing motions which are similar to motions to dismiss for failure to state a claim or motions for summary adjudication. The arbitrator shall resolve all disputes in accordance with the substantive law of California and may grant any remedy or relief that a court of such state could order or grant within the scope hereof and such ancillary relief as is necessary to make effective any award. The arbitrator shall also have the power to award recovery of all costs and fees, to impose sanctions and to take such other action as the arbitrator deems necessary to the same extent a judge could pursuant to the Federal Rules of Civil Procedure, the California Rules of Civil Procedure or other applicable law. Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction. The
institution and maintenance of an action for judicial relief or pursuit of a provisional or ancillary remedy shall not constitute a waiver of the right of any party, including the plaintiff, to submit the controversy or claim to arbitration if any other party contests such action for judicial relief.

---

9.5 Discovery. In any arbitration proceeding discovery will be permitted in accordance with the Rules. All discovery shall be expressly limited to matters directly relevant to the dispute being arbitrated and must be completed no later than 20 days before the hearing date and within 180 days of the filing of the dispute with the AAA. Any requests for an extension of the discovery periods, or any discovery disputes, will be subject to final determination by the arbitrator upon a showing that the request for discovery is essential for the partys presentation and that no alternative means for obtaining information is available.

9.6 Class Proceedings and Consolidations. The resolution of any dispute arising pursuant to the terms of this Agreement shall be determined by a separate arbitration proceeding and such dispute shall not be consolidated with other disputes or included in any class proceeding.

9.7 Payment Of Arbitration Costs And Fees. The arbitrator shall award all costs and expenses of the arbitration proceeding.

9.8 Real Property Collateral; Judicial Reference. Notwithstanding anything herein to the contrary, no dispute shall be submitted to arbitration if the dispute concerns indebtedness secured directly or indirectly, in whole or in part, by any real property unless (i) the holder of the mortgage, lien or security interest specifically elects in writing to proceed with the arbitration, or (ii) all parties to the arbitration waive any rights or benefits that might accrue to them by virtue of the single action rule statute of California, thereby agreeing that all indebtedness and obligations of the parties, and all mortgages, liens and security interests securing such indebtedness and obligations, shall remain fully valid and enforceable. If any such dispute is not submitted to arbitration, the dispute shall be referred to a referee in accordance with California Code of Civil Procedure
Section 638 et seq., and this general reference agreement is intended to be specifically enforceable in accordance with said Section 638. A referee with the qualifications required herein for arbitrators shall be selected pursuant to the AAAs selection procedures. Judgment upon the decision rendered by a referee shall be entered in the court in which such proceeding was commenced in accordance with California Code of Civil Procedure Sections 644 and 645.

9.9 Miscellaneous. To the maximum extent practicable, the AAA, the arbitrators and the parties shall take all action required to conclude any arbitration proceeding within 180 days of the filing of the dispute with the AAA. No arbitrator or other party to an arbitration proceeding may disclose the existence, content or results thereof, except for disclosures of information by a party required in the ordinary course of its business or by applicable law or regulation. If more than one agreement for arbitration by or between the parties potentially applies to a dispute, the arbitration provision most directly related to the documents between the parties or the subject matter of the dispute shall control. This Agreement may be amended or modified only in writing signed by each party hereto. If any provision of this Agreement shall be held to be prohibited by or invalid under applicable law
such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or any remaining provisions of this Agreement. This arbitration provision shall survive termination, amendment or expiration of any of the documents or any relationship between the parties.
