ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS, PRO FORMA FINANCIAL INFORMATION
        AND EXHIBITS

A.   FINANCIAL STATEMENTS OF BUSINESSES ACQUIRED

     At the time this Report on Form 8-K was filed with the Securities and
Exchange Commission, it was impracticable to provide the required financial
statements of Rainin Instrument Company, LLC. The required historical
financial statements will be filed by amendment as soon as practicable in
compliance with Item 7(a)(4) of Form 8-K.

B.   PRO FORMA FINANCIAL INFORMATION

     The Unaudited Pro Forma Combined Financial Statements required by this
Item are included on pages 3 through 8 of this Form 8-K.





                     METTLER-TOLEDO INTERNATIONAL INC.
             UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS


     The Unaudited Pro Forma Combined Financial Statements have been
prepared to give effect to the proposed acquisition of Rainin Instrument
Company, LLC ("Rainin") by Mettler-Toledo International Inc.
("Mettler-Toledo" or the "Company") as of June 30, 2001 for the balance
sheet, and for the beginning of the periods ended June 30, 2001 and
December 31, 2000 for the respective statements of operations. The Rainin
historical financial information was derived from unaudited financial
information provided by the seller.

     The pro forma data reflects adjustments directly related to the
proposed acquisition, and does not include adjustments that may arise as a
consequence of the acquisition. Accordingly, the Unaudited Pro Forma
Combined Financial Statements do not purport to be indicative of what the
Company's combined financial position or combined results of operations
would actually have been had the proposed acquisition been completed on
such date or the beginning of the periods indicated or to project the
Company's combined results of operations for any future period.

     The proposed acquisition has been accounted for under the purchase
method of accounting. Under the purchase method of accounting, tangible and
intangible assets acquired and liabilities assumed are recorded at their
estimated fair values. The Company has accounted for these estimated fair
values and related useful lives based primarily on a preliminary valuation
by an independent third party which is subject to final valuation
adjustments. The excess of the total acquisition purchase price over the
net assets acquired is classified as goodwill and is not amortized in
accordance with current generally accepted accounting principles.

     issuance of approximately 3.4 million shares of Mettler-Toledo common
     stock at a fair market value of $144.3 million.

     make additional earn-out payments of up to $60.0 million. Up to half
     of any additional contingent payment will be paid in shares of the
     Company's common stock and the remainder will be paid in cash.

            NOTES TO THE PRO FORMA COMBINED FINANCIAL STATEMENTS
                                (CONTINUED)
                   (In thousands, except per share data)

(d)  Represents the elimination of Rainin's historical equity and net
     goodwill of $944.

(e)  Reflects an adjustment to account for Rainin's trade-in program on an
     accrual basis to conform with the Company's accounting principles.

(f)  Represents an adjustment to eliminate sales, cost of sales and
     selling, general and administrative expense associated with pipette
     sales that are purchased from a direct competitor of Rainin that will
     be terminated as a result of the transaction.

     Rainin's facilities on the post-transaction negotiated "arms length"

     pro forma adjustments at the combined U.S. federal and state statutory
     tax rate of 40%, as if the transaction had occurred at the beginning
     of each period presented. Since Rainin was organized as a Subchapter S
     Corporation of the Internal Revenue Code, the Company's historical
     statements make no provisions for federal income taxes and for certain
     state income taxes where a Subchapter S election has been made.
