Exhibit 10.8 The Directors Thermo Electron Corporation 81 Wyman Street Waltham M.A. 02254 U.S.A. July 1995 Dear Sirs We are pleased to advise you that Barclays Bank PLC (the "Bank") has agreed to provide in aggregate short term facilities of up to US$100,000,000 (one hundred million United States ("US") Dollars) or its currency equivalent (referred to as the "Facility") to Thermo Electron Corporation (the "Parent") and certain Subsidiaries as may be nominated from time to time in accordance with clause 3 (such companies being individually referred to as a "Borrower", collectively the "Borrowers") as detailed below. This Facility Letter cancels and replaces the existing US$55,000,000 facility provided by the Bank to the Parent and its Subsidiaries. The Schedules attached hereto form part of the terms and conditions of this letter. The Facility will be available for utilisation by the Borrowers, subject to the following terms and conditions:- 1. Options Available Within and Utilisation of the Facility -------------------------------------------------------- The Facility may be utilised by way of the following options and in accordance with the provisions of the Schedules related thereto.- Sterling Money Market Loan (see Schedule A) and/or Sterling Overdraft (see Schedule B) and/or Currency Money Market Loan (the "Currency MML") (see Schedule C) and/or Foreign Currency Overdraft (see Schedule D) and/or Revolving Acceptance Credit (the "Credit") (see Schedule E) and/or Bonds Guarantees and Indemnities (see Schedule F) and/or Letters of Credit (see Schedule G) and/or Ancillary Facilities (see Schedule H). PAGE Within the Facility the aggregate of the liabilities due, owing or incurred thereunder shall not at any time exceed US$100,000,000 (or its currency equivalent). The US dollar equivalent of the currency or currencies utilised or available to be utilised under the Facility may be calculated by the Bank at any time by reference to the Bank's spot rate of exchange in the London Foreign Exchange Market for the sale of the relevant currency or currencies for US dollars. Allocations under the Facility that are made available to Borrowers or the Parent by branches or affiliates of the Bank in countries outside of the United Kingdom will be governed by the terms of the Facility as detailed herein, except where specifically superceded by local arrangements. 2. Availability ------------ 2.1 This offer is available to the Parent for acceptance until one Month from the date of this letter after which date the offer will lapse unless extended in writing by the Bank. Acceptance is to be signified as stated in clause 18 below. 2.2 All monies owing under the Facility are repayable upon written demand by the Bank and any undrawn portion may be cancelled by the Bank at any time. Following demand and/or cancellation, no further utilisation may be made under the Facility. If demand for repayment is made the Bank shall have in addition the right to call for full cash cover for the amount of contingent liabilities outstanding to the Bank hereunder. The Parent shall indemnify the Bank on demand against any loss or expense which the Bank may reasonably sustain or incur as a direct consequence of making such demand. In the absence of demand or cancellation by the Bank, the Facility is available for utilisation until 12 April 1996 and no liability or liabilities incurred may extend more than three months beyond the above mentioned expiry date. However, the Bank will be pleased to discuss the Borrower's requirements shortly before that date. 3. Subsidiaries as Borrowers ------------------------- 3.1 The Parent may designate any of its Subsidiaries as a Borrower under this Facility Letter by giving not less than 10 days notice thereof to the Bank. No such designation shall take effect until such Subsidiary and the Parent have executed a deed of accession in the form set out in Schedule PAGE 1, and the Bank has received and found to he reasonably satisfactory to it such other documents, (including constitutional documents, board minutes, necessary licences or consents, and legal opinions) and information as the Bank may reasonably require. In addition, no Subsidiary which has acceded as a Borrower pursuant to this clause may utilise the Facility, or any option within the Facility until the Parent has made a request pursuant to clause 3.2 below and the Bank has agreed to such request. 3.2 Following a request from the Parent in the form contained in Schedule 2, the Bank may from time to time by notice in writing to the Parent allocate to any Subsidiary of the Parent (which has acceded as a Borrower pursuant to Clause 3.1 above) a tranche of the Facility and/or one or more of the options (detailed in clause 1) contained within the Facility. If the Bank does so, that tranche will not then be available to the Parent or other Borrowers, and the Facility available to them will reduce accordingly. 3.3 Each Borrower, by its execution of the deed of accession, irrevocably appoints the Parent as its agent for all purposes of or connected with this Agreement. The Bank may rely upon any document signed by or on behalf of the Parent as if it had been signed by each and every other Borrower. The Parent may give a good receipt for any sum payable to each and every other Borrower hereunder. 4. Interest/Fees/Charges --------------------- The interest and/or fees, and/or charges payable on each option within the Facility will be calculated and be payable in accordance with the relevant schedule to this Agreement. 5 . Interest on an Overdue Amount ----------------------------- 5.1If any moneys payable under this Facility are not paid when due by the Borrowers or the Parent: (i) interest will be charged on the overdue amounts, on a daily basis, from the due date to the date of actual payment; (ii) the amount of such interest shall be calculated by reference to successive interest periods, (the duration of such interest periods shall be selected by the Bank at its discretion). 5.2Interest shall be charged at the rate per annum determined by the Bank to be equal to 1% above the rate which would otherwise have been applicable to such overdue amount under the provisions of the relevant Schedule if such amount had been non-overdue principal (except that in the case of any PAGE amount that does not have an applicable interest rate hereunder the rate charged shall be 2% per annum over the Bank's Base Rate rate current from time to time). Interest so accrued shall be due on demand or (in the absence of demand) on the last day of the default interest period in which it accrued and, if unpaid, shall be compounded on the last day of that and each successive interest period. Interest on overdue amounts shall be charged and compounded on this basis after as well as before any judgement obtained hereunder. 6. Guarantees ---------- The repayment of each Borrower's obligations hereunder will be guaranteed by the Parent by the execution of a guarantee acceptable to the Bank in the principal sum of US$100,000,000 plus interest and other liabilities as detailed therein. 7. Fees ---- The Parent shall pay to the Bank the following fees: (i) an arrangement fee of #65,000 upon acceptance by the Parent of the Facility; and (ii) a facility fee of #35,000 per annum annually in advance during the continuation of the Facility. 8. Cancellation ------------ Any undrawn part of the amount of the Facility may be cancelled by the Parent in minimum amounts of US$1,000,000 and multiples of US$500,000 subject to the Parent giving the Bank not less than seven days' notice in writing (such notice, once given, shall be irrevocable). Amounts which are cancelled will no longer be available for drawing. 9. Change of Circumstances ----------------------- In the event of any change in applicable law or regulation or the existing requirements of, or any new requirements being imposed by, the Bank of England or other regulatory authority the result of which, in the sole opinion of the Bank, is to increase the cost to it of funding, maintaining or making available the Facility (or any undrawn amount thereof) or to reduce the effective return to the Bank then the Borrowers and/or, as appropriate, the Parent shall pay to the Bank, upon receipt of documentation evidencing such increased cost or reduction, as the case may be, such sum as may be certified by the Bank to the Borrowers and/or the Parent as shall compensate the Bank for such increased cost or such reduction. PAGE 10. Set-off ------- Any sum of money at any time standing to the credit of a Borrower or the Parent with the Bank in any currency upon any account or otherwise (whether or not any such account is held in such Borrower's or the Parent's name) or provided to the Bank as cash cover for any bills and/or any outstanding liabilities under the Facility, may be applied by the Bank at any time (upon 5 Business Days written notice to such Borrower and the Parent) in or towards the discharge of any money or liabilities now or hereafter due, owing or incurred to the Bank by such Borrower or the Parent hereunder (whether as principal or surety). 11. Indemnity --------- 11.1 The Parent shall indemnify the Bank on demand (without prejudice to the Bank's other rights) for any expense, loss or liability reasonably incurred by the Bank in consequence of (i) any default or delay by the Borrowers or the Parent in the payment of any amount when due under this letter, or (ii) all or part of the Facility being prepaid or becoming repayable otherwise than on the maturity of the then current interest period including, without limitation any loss (including loss of margin), expense or liability sustained or incurred by the Bank in any such event in liquidating or re-deploying funds acquired or committed to fund, make available or maintain the Facility (or any part of it). 11.2 If, for any reason, any amount payable under this letter is received or recovered in a currency (the "other currency") other than that in which it is required to be paid hereunder (the "contractual currency"), then to the extent that the payment to the Bank (when converted to the contractual currency at the then applicable rate of exchange) falls short of the amount so payable under this letter, the Parent shall, as a separate and independent obligation, fully indemnify the Bank against the amount of the shortfall. For the purpose of this sub-clause the expression "rate of exchange" means the rate at which the Bank is able as soon as practicable after receipt to purchase the contractual currency in London with the other currency. 12. Illegality ---------- If, at any time, the Bank determines that it is, or will become unlawful or contrary to any directives of any agency or any country or state for it to make, fund or allow to remain outstanding all or part of the Facility, and/or carry out all or any of its other obligations towards the Borrowers and the Parent under this letter, then upon the Bank notifying the Parent of such event, within 30 days of that notification or such earlier date (if any) as the Bank PAGE shall certify to be necessary to comply with the relevant law or directive, the Borrowers and/or the Parent (as appropriate) shall prepay any principal amounts outstanding together with any accrued interest thereon. 13. Representations and Warranties ------------------------------ 13.1 By accepting this letter the Parent and each Borrower represents and warrants that: (a) Statutes: The Parent and each of its Material --------- Subsidiaries are duly organised, existing and (where relevant) in good standing under the laws of the jurisdictions of their respective incorporation and have the corporate power and authority to own their respective property and assets and to transact the businesses in which they respectively are engaged or presently propose to engage and are duly qualified and (where relevant) in good standing as foreign corporations. (b) Corporate Power and Authority: Borrowers: Each of the ----------------------------------------- Borrowers has the corporate power, and has taken all necessary corporate action (including, without limitation, any consent of stockholders required by law or by its constitutional documents) to authorise it to execute, deliver and perform the terms and provisions of and to incur its obligations under this Agreement and to borrow hereunder or otherwise utilise the Facility. This Agreement has been or, when executed, will be duly authorised, executed and delivered by each Borrower and constitutes the legal, valid and binding obligation of that Borrower enforceable in accordance with its terms (except as the enforceability thereof may be limited by insolvency or similar laws of general application affecting creditors' rights and by general principles of equity). (c) Corporate Power and Authority: Guarantor: The Parent as ----------------------------------------- Guarantor has the corporate power and has taken all necessary corporate action (including, without limitation, any consent of stockholders required by law or by its constitutional documents) to authorise it to execute deliver and perform the terms and provisions of and to incur its obligations under the Guarantee. The Guarantee has been duly authorised executed and delivered by the Parent thereto and will when executed constitute the legal valid and binding obligation of the Parent enforceable in accordance with its terms (except as the enforceability thereof may be limited by insolvency or similar laws of general application affecting creditors' rights and by general principles of equity). PAGE (d) Compliance with other Instruments: Neither the Parent ---------------------------------- nor any Material Subsidiary is in default under any material agreement to which it is a party, and the execution, delivery and performance by each Borrower and the Parent, as the case may be, of this Agreement and the Guarantee (a) will not contravene any provision of Applicable Law, (b) will not conflict with or be inconsistent with or result in any breach of any of the terms, covenants, conditions or provisions of, or constitute a default under, or result in the creation or imposition of any Encumbrance on any of the property or assets of the Parent or any Material Subsidiary pursuant to the terms of any indenture, mortgage, deed to secure debt, deed of trust, or other material agreement or instrument to which the Parent or any Material Subsidiary is a signatory or by which it is bound or to which it may be subject, (c) will not violate any provision of the constitutional documents of the Parent or any corporate Material Subsidiary and (d) will not require any Governmental Approval. (e) Financial Statements of Group: The consolidated ----------------------------------- financial statements of the Parent and its Subsidiaries dated 1st January 1994 and the related consolidated statements of income (including the notes thereto), are all true and correct in all material respects and present fairly the consolidated financial condition of the Parent and its Subsidiaries at that date and the results of their operations for the year then ending. To the Parent's knowledge neither the Parent nor any Material Subsidiary had as at such date any significant liabilities, material to the Parent and its subsidiaries on a consolidated basis, contingent or otherwise (including liabilities for Taxes or any unusual forward or long-term commitments) which were not disclosed by or reserved against in the financial statements referred to above or in the notes thereto, and there are no material unrealised or anticipated losses from any unfavourable commitments of the Parent. All such financial statements were prepared in accordance with generally accepted accounting principles applied on a consistent basis throughout the periods involved. Since 1st January 1994 there has been no material adverse change in the operations, business, property or assets of, or in the condition (financial or otherwise) or prospects of, the Parent and its Material Subsidiaries, taken as a whole. (f) Governmental Approvals: No Governmental Approval is ------------------------ required to authorise, or is required in connection with the execution, delivery and performance of this Agreement or the Guarantee.

None of those properties is subject to any Encumbrance except as referred to in those financial statements and possible title defects and Encumbrances which do not materially interfere with the use or materially detract from the value of such properties or the operations of the Parent or the relevant Material Subsidiary. (h) Taxes : Each of the Parent and its Material Subsidiaries ----- has filed or caused to be filed all declarations, reports and tax returns including, in the case of the Parent and each Material Subsidiary located in the United States, all federal and state income tax returns which it is required by law to file, and has paid all Taxes which are shown as being due and payable on such returns or on any assessments made against it or any of its properties. The accruals and reserves on the books of the Parent and its Material Subsidiaries in respect of Taxes are adequate for all periods. Neither the Parent nor any Material Subsidiary has any knowledge of any unpaid adjustment, assessment or any penalties or interest of significance, or any basis therefor, by any taxing authority for any period, except those being contested in good faith and by appropriate proceedings which effectively stay the enforcement of any Encumbrance and the attachment of a penalty. (i) Solvency: The Parent (i) acknowledges that it will have --------- received, before the execution of its Guarantee, fair consideration and reasonably equivalent value for the obligations incurred or to be incurred by it thereunder, (ii) represents and warrants that after giving effect to such obligations (1) the present fair saleable value of the assets of it exceeds its liabilities in that it retains sufficient capital reasonably to anticipate the needs and risks of its ongoing business, and (2) it has not incurred (actually or contingently) debts beyond its ability to pay such debts as they mature, and that the present fair saleable value of its assets is greater than that needed to pay its probable existing debts as they become due. (j) Disclosure: Neither this Agreement, nor any other ---------- document, certificate or statement furnished to the Bank by or on behalf of either Borrower or the Parent in connection herewith contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements contained herein and therein not misleading. There is no fact peculiar to the Parent or any of its Material Subsidiaries which materially adversely affects or may PAGE (as far as the Parent can now foresee) materially adversely affect the business, property or assets, or financial condition of the Parent and its Material Subsidiaries taken as a whole which has not been set out in this Agreement, or in the other documents, certificates and statements furnished to the Bank by or on behalf of the Parent, prior to the date hereof in connection with the transactions contemplated by this letter. 13.2Each party providing the same shall be deemed to repeat the representations and warranties contained in the preceding sub-clause on each occasion on which there is any utilisation of the Facility by reference to the circumstances then existing. 14. Positive Covenants ------------------ 14.1 Use of Proceeds --------------- Each Borrower undertakes that the proceeds of the Facility will be used for the general working capital purposes of the Borrowers. None of such proceeds shall be used to purchase or carry, or to reduce or retire or refinance any credit incurred to purchase or carry, any margin stock (within the meaning of Regulations U and X) or to extend credit to others for the purpose of purchasing or carrying any such margin stock. If requested by the Bank, the Parent will deliver statements in conformity with the requirements of Federal Reserve Form U-l referred to in Regulation U. 14.2 Financial Information for Group ------------------------------- The Parent will deliver to the Bank: (a) within 90 days after the end of each year of the Parent and its Subsidiaries an audited consolidated balance sheet of the Parent as at the end of such year, and audited consolidated statements of income and cash flow of the Parent and its Subsidiaries for such year, all in reasonable detail and with the unqualified opinion of Arthur Andersen (or other independent certified public accountants of recognised standing selected by the Parent and reasonably satisfactory to the Bank) together with the management letter prepared in connection with such audited financial statements, provided that the Parent may make a change in its accounting principles in any year, so long as (w) such change or changes are clearly reflected in the annual audit report, and (x) any principle has been concurred in by the Parent and the Parent's independent certified public accountants and is in accordance with generally accepted accounting principles;

and (c) with reasonable promptness, such further information regarding the business affairs and financial condition of the Parent or any Material Subsidiary as the Bank may reasonably request. 14.3 Maintenance of Books: Inspection of Property and Records -------------------------------------------------------- The Parent shall and shall procure that each of its Material Subsidiaries shall prepare or cause to be prepared (a) its annual statements and reports in accordance with generally accepted accounting principles and permit any person designated by the Bank to visit and inspect any of its properties, corporate books and financial records, and to discuss its accounts, affairs and finance with the principal officers of the Parent and such Material Subsidiary during reasonable business hours, and upon reasonable prior notice, from time to time, as the Bank may reasonably request and (b) its interim statements and reports in accordance with methods historically used by such Material Subsidiary, as the case may be, as such methods have yielded financial information which has historically not required material annual adjustments to bring such information into compliance with generally accepted accounting principles. 14.4 Maintenance of Properties ------------------------- The Parent shall and shall procure that each of its Material Subsidiaries shall maintain, preserve, protect and keep, or cause to be maintained, preserved, protected and kept, its properties and every part thereof in good repair, working order and condition, and from time to time will make or cause to be made all needful and proper repairs, renewals, replacements, extensions, additions, betterments, and improvements thereto, so that the business carried on in connection therewith may be properly and advantageously conducted at all times Provided that the Parent and its Material Subsidiaries shall not be obliged to repair or replace any such properties which have become obsolete or unsuitable or inadequate for the purpose for which they are used. 14.5 Maintenance of Insurance ------------------------ The Parent shall and shall procure that each of its Material Subsidiaries shall maintain liability and worker's compensation insurance (or maintain a legally sufficient, fully funded, programme of self-insurance against worker's PAGE compensation liabilities), adequate insurance on its properties against such hazards and in at least such amounts as is customary in the business and, at the request of the Bank, the Parent will forthwith deliver an officer's certificate specifying the details of the insurance then in effect. 14.6 Taxes ----- The Parent shall and shall procure that each of its Material Subsidiaries shall pay and discharge all Taxes prior to the date on which penalties attach thereto, and will pay all Taxes which, if unpaid, might become an Encumbrance upon any of its property Provided that the Parent and its Material Subsidiaries shall not be required to pay and discharge any such Tax so long as the legality or amount thereof shall be promptly contested in good faith and by appropriate proceedings which effectively stay the enforcement of any Encumbrance and the attachment of a penalty and the Parent or such Material Subsidiary, as the case may be, shall have set aside appropriate reserves therefor in accordance with generally accepted accounting principles. 14.7 Existence and Status -------------------- The Parent and each of its Material Subsidiaries which is a corporation shall maintain its corporate existence and (where relevant) good standing in its state of incorporation and its qualification and (where relevant) good standing as a foreign corporation in all jurisdictions where its ownership of property or its business activities cause such qualification to be required. 14.8 Litigation ---------- The Parent shall give prompt notice to the Bank of any material pending legal proceedings. For the purposes of this Clause 14.8, only pending legal proceedings which would be required to be reported by the Parent for Securities and Exchange Commission Filings need be reported to the Bank. 14.9 Stockholder Reports, etc ------------------------ Promptly after the same are available, the Parent will provide to the Bank copies of all publicly available current reports on Form 8-K, proxy statements and prospectuses filed with the Securities and Exchange Commission under the Securities Act 1933, as amended or the Securities Exchange Act 1934 as amended, as the case may be, (excluding prospectuses relating to employee stock option or benefit plans). 15.
