 Item 1.01.    Entry into a Material Definitive Agreement.

On December 19, 2014, IDEXX Laboratories, Inc. (the "Company") entered into a Multicurrency Note Purchase and Private Shelf Agreement among the Company, Metropolitan Life Insurance Company ("MetLife"), and each of the accredited institutional purchasers named therein (the "Existing Agreement"). Pursuant to the terms of the Existing Agreement, the Company may request that MetLife purchase, over the three-year period beginning on December 19, 2014, up to $50 million of additional senior promissory notes of the Company at a fixed interest rate and with a maturity date not to exceed fifteen years (the "Shelf Notes").

On March 14, 2019, the Company entered into the First Amendment to Multicurrency Note Purchase and Private Shelf Agreement (the "Amendment", and together with the Existing Agreement as amended, the "Agreement") in order to (i) increase the Shelf Notes facility size from $50 million to $150 million, (ii) extend the Shelf Notes facility issuance period from December 19, 2017 to December 20, 2021 and (iii) make various implementing and administrative changes in order to facilitate a $100 million Shelf Notes issuance on March 14, 2019.

On March 14, 2019, the Company submitted to MetLife a request (the "Request for Purchase") requesting that MetLife and other purchasers purchase $100 million of the Company’s Shelf Notes on March 14, 2019 (the "Series C Notes"). The Company anticipates using the proceeds received from the Series C Notes for general corporate purposes, including repayments of debt. The Series C Notes contain the following principal terms.
Maturity Date: The entire outstanding principal balance of the Series C Notes is due and payable on March 14, 2029 (the "Maturity Date").

Interest: The Series C Notes bear interest at the rate of 4.19% per annum. Interest payments are due semi-annually in arrears on March 14 and September 14 of each year, commencing on September 14, 2019. All accrued but unpaid interest due is payable on the Maturity Date.

Prepayment, Acceleration and Events of Default: The obligations of the Company under the Series C Notes may be accelerated upon the occurrence of an event of default under the Agreement, which includes customary events of default including, without limitation, payment defaults, defaults in the performance of affirmative and negative covenants, the inaccuracy of representations or warranties, bankruptcy and insolvency related defaults, defaults relating to judgments, an ERISA event and the failure to pay specified indebtedness.

Covenants: The Agreement contains affirmative, negative and financial covenants customary for agreements of this type. The negative covenants include restrictions on liens, indebtedness of subsidiaries of the Company, priority indebtedness, fundamental changes, investments, transactions with affiliates, certain restrictive agreements and violations of laws and regulations. The financial covenant is a consolidated leverage ratio test. The obligations of the Company will be unconditionally guaranteed by each of its subsidiaries that guarantees the obligations of the Company under a material credit facility (but excluding any foreign subsidiary that does not guarantee indebtedness of the Company or any US subsidiaries under a material credit facility).

On March 14, 2019, the Company submitted to MetLife a Confirmation of Acceptance indicating the Company’s acceptance and issuance of the Series C Notes on such date.

The foregoing description of the Amendment is qualified in its entirety by reference to the Amendment, which is filed as Exhibit 10.2 hereto and incorporated herein by this reference.
