(d) That no contract right, account general intangible or chattel paper is or will be represented by any note or other instrument (negotiable or otherwise), and that no contract right or account is, or will be represented by any conditional or installment sales 5 obligation or other chattel paper, except such instruments or chattel paper as have been or forthwith upon receipt by the Borrower following the occurrence and during the continuation of an Event of Default and the giving of notice by the Bank as provided in Section 7.2 of the Loan Agreement will be delivered to the Bank (duly endorsed or assigned, as may be appropriate), such delivery, in the case of chattel paper, to include all executed copies except those in the possession of the installment buyer (provided, that if the Bank elects to leave chattel paper in the possession of the Borrower, such procedure shall be subject to the Borrower's compliance with the provisions of Paragraph 10 hereof and to the Bank's right to require delivery and endorsement or assignment of such chattel paper by the Borrower to the Bank whenever the Bank shall so request); and following the occurrence and during the continuation of an Event of Default and the giving of notice by the Bank as provided in Section 7.2 of the Loan Agreement any security for or guaranty of any of the Collateral shall be delivered to the Bank immediately upon receipt thereof by the Borrower, with such assignments and endorsements thereof as the bank may request.

(f) That the Bank shall not be deemed to have assumed any liability or responsibility to the Borrower or any third person for the correctness, validity or genuineness of any instruments or documents that may be released or endorsed to the Borrower by the Bank (which shall automatically be deemed to be without recourse to the Bank in any event), or for the existence, character, quantity, quality, condition, value or delivery of any goods purporting to be represented by any such documents; and that the Bank, by accepting such security interest in the Collateral, or by releasing any Collateral to the Borrower, shall not be deemed to have assumed any obligation or liability to any supplier or Debtor or to any other third party, and the Borrower agrees to indemnify and defend the Bank and hold it harmless in respect to any claim or proceeding arising out of any matter referred to in this Paragraph 13(f).

If the outstanding Loans exceed the Borrowing Base calculated after the exclusion of assets as a result of such casualty, then, at the Bank's election, exercised in its sole discretion, within thirty (30) days of notice, the Borrower shall pay, to the Bank such amount so that the Borrower is in compliance with the Borrowing Base, or, alternatively, provide substitute collateral which is satisfactory to the Bank in its sole discretion.

(j) That if any of the Collateral includes a charge for, or if any loan by the Bank to the Borrower shall be subject to any tax payable to any governmental taxing authority, the Borrower shall pay such tax independently when due. The Borrower will indemnify and save the Bank harmless from any loss, cost, liability or expense (including, without limitation, reasonable attorney's fees), in connection therewith other than such as shall be caused by the Bank's willful misconduct, gross negligence or acts taken in bad faith. (k) That at any time or times after the occurrence and during the continuation of an Event of Default, the Bank may notify any Debtor or Debtors of its security interest in the Collateral and collect all amounts due thereon; and the Borrower agrees, at the request of the Bank, to notify all or any of the Debtors in writing of the Bank's security interest in the Collateral in whatever manner the Bank requests, and if the Bank so requests, to permit the Bank to mail such notices at the Borrower's expense. (l) That the Bank may, at its option, from time to time, discharge any taxes, liens or encumbrances on any of the Collateral not permitted by the Loan Agreement, or take any other action that the Bank may deem proper to maintain or preserve its security interest in the Collateral, and the Borrower will pay to the Bank on demand or the Bank in its sole discretion may charge to the Borrower all amounts so paid or incurred by it or as a debit charge against the Borrower's loan account, if any, or any other deposit account of the Borrower with the Bank. (m) If any of Borrower's accounts arise out of contracts with the United States or any department, agency, or instrumentality thereof, Borrower will immediately notify Bank thereof in writing and execute any instruments and take any steps required by Bank in order that all monies due and to become due under such contracts shall be assigned to Bank and notice thereof given to the Government under the Federal Assignment of Claims Act. (n) That all representations now or hereafter made by the Borrower to the Bank, whether in this Agreement or in any supporting or supplemental reports, statements 7 or documentation, including, without limitation, statements relating to the Collateral and financial statements, are, and will be, at and as of the date when made true and correct in all material respects. (o) Except for the Bank's gross negligence or willful misconduct or acts taken in bad faith, Borrower will indemnify and save Bank harmless from all loss, costs, damage, liability or expenses (including, without limitation, court costs and reasonable attorneys, fees) that Bank may sustain or incur by reason of defending or protecting this security interest or the priority thereof or enforcing the Obligations, or in the prosecution or defense of any action or proceeding concerning any matter growing out of or in connection with this Agreement and/or any other documents now or hereafter executed in connection with this Agreement and/or the Obligations and/or the Collateral. This indemnity shall survive the repayment of the Obligations and the termination of Bank's agreement to make loans available to Borrower and the termination of this Agreement. 14. The Borrower hereby irrevocably constitutes and appoints the Bank as the Borrower's true and lawful attorney, with full power of substitution, at the sole cost and expense of the Borrower but for the sole benefit of the Bank, to be exercised only after the occurrence and during the continuation an Event of Default and the giving of the notice as provided by Section 7.2 of the Loan Agreement, to convert the Collateral into cash, including without limitation, the sale (either public or private) of all or any portion or portions of the Inventory and other Collateral; to enforce collection of the Collateral, either in its own name or in the name of the Borrower, including, without limitation, executing releases, compromising or settling with any Debtors and prosecuting, defending, compromising or releasing any action relating to the Collateral; to notify Post Office authorities to change the address for delivery of mail addressed to the Borrower to such address as the Bank shall designate; to receive, open and dispose of all mail addressed to the Borrower received at such address and to take therefrom any remittances or proceeds of Collateral in which the Bank has a security interest; to endorse the name of the Borrower in favor of the Bank upon any and all checks, drafts, money orders, notes, acceptances or other instruments of the same or different nature received at such address; to sign and endorse the name of the Borrower on and to receive as secured party any of the Collateral, any invoices, schedules of Collateral, freight or express receipts, or bills of lading, storage receipts, warehouse receipts, or other documents of title of the same or different nature relating to the Collateral; to sign the name of the Borrower or any notice to the Debtors or on verification of the Collateral; and to sign and file or record on behalf of the Borrower any financing or other statement in order to perfect or protect the Bank's security interest. The Bank shall not be obliged to do any of the acts or exercise any of the powers hereinabove authorized, but if the Bank elects to do any such act or exercise any such power, it shall not be accountable for more than it actually receives as a result of such exercise of power, and it shall not be responsible to the Borrower except for willful misconduct, gross negligence, or acts taken in bad faith. All powers conferred upon the Bank by this Agreement, being coupled with an interest, shall be irrevocable so long as any Obligation of the Borrower to the Bank shall remain unpaid. Additionally, whether or not there is an Event of Default, the Borrower hereby authorizes the Bank, at any time, and from time to time, to file UCC financing statements, amendments and continuations statements in the name of the Borrower, as debtor, to perfect the security interests in the Collateral granted hereby in such jurisdictions as the Bank deems necessary or appropriate without any signature of the Borrower or the Bank to the extent permitted in such jurisdictions. 8 Whenever the Bank deems it desirable that any legal action be instituted with respect to any Collateral or that any other action be taken in an attempt to effectuate collection of any Collateral, the Bank may reassign the item in question to the Borrower (and if the Bank shall execute any such reassignment, it shall automatically be deemed to be without recourse to the Bank in any event) and require the Borrower to proceed with such legal or other action at the Borrower's sole liability, cost and expense, in which event all amounts collected by the Borrower on such item shall nevertheless be subject to the provisions of Paragraph 3 of this Agreement. 15. The Bank is hereby authorized, at its election, at any time or times after an Event of Default has occurred and during the continuation thereof, if the Bank has given the notice as provided by Section 7.2 of the Loan Agreement, and without any further demand or notice except to such extent as notice may be required by applicable law, to sell or otherwise dispose of all or any of the Collateral at public or private sale, and the Bank may also exercise any and all other rights and remedies of a secured party under the Code or which are otherwise accorded to it by applicable law, all as the Bank may determine. If notice of a sale or other action by the Bank is required by applicable law, the Borrower agrees that ten (10) days' written notice to the Borrower, or the shortest period of written notice permitted by such law, whichever is larger, shall be sufficient; and that to the extent permitted by such law, the Bank, its officers, attorneys and agents may bid and become purchasers at any such sale, if public, and may purchase at any private sale any of the Collateral that is of a type customarily sold on a recognized market or which is the subject of widely distributed standard price quotations, and any sale (public or private) shall be free from any right of redemption, which the Borrower hereby waives and releases. No purchaser at any sale (public or private) shall be responsible for the application of the purchase money other than the Bank. Any balance of the net proceeds of sale remaining after paying all direct Obligations of the Borrower to the Bank, and all costs and expenses of manufacturer, processing, completion or installation of the Inventory; collection, storage, custody, sale and delivery of the Inventory, and/or the Collateral, including, without limitation, reasonable attorneys' fees, and after retaining as collateral security or applying as the Bank may elect (in whole or in part at any time and from time to time) amounts equal to the aggregate of all other Obligations shall be returned to the Borrower or to such other party as may be legally entitled thereto; and if there is a deficiency, the Borrower shall be responsible for the same, with interest as provided in the Loan Agreement. Upon demand by the Bank, the Borrower shall assemble the Collateral and make it available to the Bank at a place designated by the Bank which is reasonably convenient to the Bank and the Borrower. 16. The Borrower waives notice of nonpayment, demand, presentment, protest or notice of protest of the Collateral, and all other notices, consents to any renewals or extensions of time of payment thereof, and generally waives any and all suretyship defenses and defenses in the nature thereof. No delay or omission of the Bank in exercising or enforcing any of its rights, powers, privileges, remedies, immunities or discretions (all of which are hereinafter collectively referred to as the "BANK'S RIGHTS AND REMEDIES") hereunder shall constitute a waiver thereof; and no waiver by the Bank of any default of the Borrower hereunder shall operate as a waiver of any other default hereunder. No term or provision hereof shall be waived, altered or modified except with the prior written consent of the Bank, which consent makes explicit reference to this Agreement. Except as provided in the preceding sentence, no other agreement or transaction, of whatsoever nature, entered into between the Bank and the Borrower at any time (whether before, during or after the effective date or term of this Agreement), shall be construed in any particular as a waiver, modification or limitation of any of the Bank's rights and remedies under this Agreement (nor shall anything in this Agreement be construed as a waiver, modification or limitation of any of the Bank's rights and remedies under any such other agreement or transaction) but all of the Bank's rights and remedies not only under the provisions of this 9 Agreement but also under any such other agreement or transaction shall be cumulative and not alternative or exclusive, and may be exercised by the Bank at such time or times and in such order of preference as the Bank in its sole discretion may determine. 17. If any provision of this Agreement or portion of such provision or the application thereof to any person or circumstance shall to any extent be held invalid or unenforceable, the remainder of this Agreement (or the remainder of such provision) and the application thereof to other persons or circumstances shall not be affected thereby. 18. This Agreement shall be binding upon and inure to the benefit of the respective successors and assigns of the parties hereto, and shall remain in full force and effect (and the Bank shall be entitled to rely thereon, notwithstanding payment of all Obligations of the Borrower to the Bank at any time or times) until terminated as to future transactions by written notice from either party to the other party of the termination hereof; provided that any such termination shall not release or affect any Collateral in which the bank already has a security interest or any Obligations incurred or rights accrued hereunder prior to the effective date of such notice (as hereinafter defined) of such termination. Notwithstanding any such termination, the Bank shall have a security interest in all Collateral to secure the payment and performance of Obligations arising after such termination as a result of commitments or undertakings made or entered into by the Bank prior to such termination. Upon the later to occur of the effective date of any such termination and the date on which all Obligations are paid in full, the Bank shall terminate its security interests in the Collateral and the Bank shall deliver to Borrower termination statements with respect thereto. The Bank may transfer and assign this Agreement and deliver the Collateral to the assignee, who shall thereupon have all of the rights and obligations of the Bank; and the Bank shall then be relieved and discharged of any responsibility or liability with respect to this Agreement and the Collateral. 19. This Agreement is intended to take effect as a sealed instrument and has been executed or completed and is to be performed in Massachusetts, and it and all transactions thereunder or pursuant thereto shall be governed as to interpretation, validity, effect, rights, duties and remedies of the parties thereunder and in all other respects by the domestic laws of The Commonwealth of Massachusetts. 20. Notwithstanding the existence of any other security interests in the Collateral described in this Agreement held by the Bank or by any other party, or the existence of any other mortgage or security interest in any other property or collateral of the Borrower or of any co-obligor, guarantor or endorser held by the Bank or any other party, the Bank shall have the right to determine the order in which any or all of said collateral and property, including the Collateral, shall be subjected to the remedies provided herein and in any other security agreement or mortgage granted by the Borrower or any other party and the right to determine the order in which any or all portions of the Obligations secured hereby are satisfied from the proceeds realized upon the exercise of the remedies provided herein or therein. The Borrower and any party who consents to this interest in the said Collateral and other property and who has actual or constructive notice hereof hereby waives and shall be deemed to have waived any and all rights to require the marshalling of assets in connection with the exercise of any of the remedies permitted by applicable law or provided herein. 21. All notices, requests, demands, claims and other communications required or permitted to be delivered, given or otherwise provided under this Agreement must be in writing and must be delivered, given or otherwise provided: 10 (a) by facsimile (in which case, it will be effective upon receipt of confirmation of good transmission), with a copy via overnight delivery by a nationally recognized courier service; or (b) by overnight delivery by a nationally recognized courier service (in which case, it will be effective on the Business Day after being deposited with such courier service); in each case, to the address (or facsimile number) listed below: If to the Borrower: ------------------ BTU International, Inc. 23 Esquire Road North Billerica, Massachusetts 01862, Attention: President Phone: (978) 667-4111 Fax: (978) 667-3377 With a copy to: Peter H.

The Credit Facility has been made and is governed by the following documents: 1. The Original Note; 2. The Original Loan Agreement; and 3. Various other documents, instruments, and agreements executed in connection therewith (collectively, with the Original Note and the Original Loan Agreement, the "ORIGINAL LOAN DOCUMENTS"). Except as otherwise provided herein or in the Closing Documents (hereinafter defined), the provisions of the Original Loan Documents shall remain unmodified and in full force and effect. As of the date hereof, the sum of zero ($0) Dollars have been advanced under the Revolving Loan. B. Purpose. The purpose of this Agreement is to set forth the terms, provisions and conditions upon which certain modifications shall be made by and among the parties with respect to the Credit Facility and to address certain other financial accommodations being made to Borrower.

The Borrower hereby ratifies and confirms that each of the Original Loan Documents, as modified by the First Amendment and the Closing Documents (collectively the "LOAN DOCUMENTS"), remain in full force and effect and agrees that the outstanding balance due and payable to Lender under the Loan Documents is set forth in Section I.A. hereof. The Borrower further agrees that the advances under the Credit Facility are due and payable in accordance with the terms of the Loan Documents, without any offset, counterclaim or other claim against Lender of any nature whatsoever as of the date hereof. Without limiting the generality of the foregoing, the Borrower hereby agrees that outstanding advances under the Revolving Loan are due and payable in accordance with the terms of the Amended Note without any offset, counterclaim or other claim against the Lender of any nature whatsoever as of the date hereof.

The Borrower acknowledges and agrees that neither Lender, nor any person, firm, corporation or entity acting on behalf of Lender has made any representation or promise to the Borrower which is not expressly set forth herein. D. Events of Default. An "Event of Default" under the Loan Agreement shall be deemed to have occurred (i) if the Borrower fails fully and timely to perform all obligations to be performed by it under this Agreement; or (ii) if any warranty or representation of the Borrower under any of this Agreement or the Closing Documents proves to have been false or misleading in any material respect when made. E. Reservation of Rights. Upon the occurrence of an Event of Default under this Agreement, Lender reserves any and all of its rights that it may have against the Borrower or any other obligor, maker or guarantor under the Loan Documents. F. Costs and Expenses.

No 3 waiver by any party hereto of any condition hereunder for its benefit (unless the time specified herein for exercise of such right or satisfaction of such condition has expired) shall constitute a waiver of any other or further right nor shall any single or partial exercise of any right preclude other or further exercise thereof or any other rights. The waiver of any breach shall not be deemed a waiver of any other or subsequent breach. No extensions of time for the performance of any obligations shall be deemed or construed as an extension of time for the performance of any other obligation. M. Further Instruments.

Without limiting the generality of the preceding sentence, the Borrower shall execute, acknowledge and deliver such instruments as Lender reasonably may request to further evidence, secure, effectuate or perfect its obligations to Lender under the Loan Documents or Lender's interest or priority in the collateral granted to secure such obligations. N. Counterparts. This Agreement may be executed in one or more counterparts, each of which when so executed and delivered shall be deemed an original, but all of which taken together shall constitute but one and the same instrument. O. Severability. If any term or provision of this Agreement or the application thereof to any person or circumstance shall to any extent be invalid or unenforceable, the remainder of this Agreement, or the application of such term or provision to such person or circumstance other than those to which it is held invalid or unenforceable, shall not be affected thereby and each term and provision of this Agreement shall be valid and enforced to the fullest extent permitted by law.
