FORECASTS: IDEXX shall furnish to Moss not less than 30 days before the commencement of each calendar quarter during the term of this Agreement a forecast of the quantity of the Products for which IDEXX expects to submit Orders in such calendar quarter and the three succeeding calendar quarters.  Each such forecast after the first shall update and replace prior forecasts as to the calendar quarters covered by such prior forecasts.  It is understood that such forecasts are merely estimates and are not to be considered Orders.

LOT ACCEPTANCE:

A.            As soon as such is available, Moss shall ship to IDEXX a sample (the "Sample") of each manufacturing lot from which an order of [**] (Part Nos.: 23-08303-00 and 23-01788-00) is to be filled.  All quantities represented by the Sample shall be included in any invoice that Moss provides to IDEXX relating to such lot of Products.  IDEXX shall use such Sample for the purpose of subjecting it to inspection and performance testing.  IDEXX shall have a maximum of [**] business days from receipt of a Sample to complete such testing and notify Moss in writing of acceptance or rejection of the Sample.  If IDEXX does not deliver such written notice to Moss within such [**] business day period, Moss shall be authorized to ship the Product in accordance with the Orders. If IDEXX notifies Moss that IDEXX has rejected the Sample, Moss shall, within twenty business days, replace the rejected Product and submit a new Sample to IDEXX for testing.

TERM: The date of this Agreement through termination by either party by providing written notice of termination not less than 24 months’ prior to the effective date of such termination.

ESCROW: Moss hereby agrees to deposit copies of Moss’ manufacturing information relating to the Products (as such documentation currently exists) with Iron Mountain Intellectual Property Management, Inc. (the “Escrow Agent”) for the Escrow Agent to keep in confidence and to be released to IDEXX solely upon the occurrence of certain triggering events as more particularly described below.  Moss further agrees to update its deposit of such information from time to time as required so that the information on deposit with the Escrow Agent is complete, current and accurate.  Upon Moss depositing its manufacturing information with the Escrow Agent, or upon Moss’ updating of such manufacturing information thereafter, IDEXX’s operations manufacturing manager, technical support manager or quality support manager ([**]) shall have the opportunity to review such manufacturing information to verify that such information is in a form that would allow IDEXX to use such information to manufacture the Products upon the occurrence of one of the triggering events discussed below.  Prior to its review of any manufacturing information (either upon initial deposit or the updating of such information), IDEXX shall provide Moss with the name of the person who shall conduct such review.  Representatives from Moss shall have the right and opportunity to be present for the duration of such review.  Following such review, Moss’ manufacturing documents shall be immediately placed in the possession of the Escrow Agent and shall not be viewed again by anyone at IDEXX unless and until the occurrence of one of the triggering events listed below.

IDEXX and Moss agree that the Escrow Agent shall be only be permitted to release Moss’ manufacturing documents to IDEXX upon the occurrence of one of the following triggering events: (i) Moss or a successor in interest to Moss by merger, by operation of law, assignment, purchase or otherwise, ceases to provide the Products to IDEXX, (ii) Moss has a receiver, administrator or liquidator appointed to the whole or any substantial part of its assets or if an order is made or a resolution passed for the winding up of Moss which is not revoked within thirty (30) days, (iii)  Moss fails, for any reason, including on account of an event of force majeure as described below, to deliver on a timely basis all quantities of Products ordered pursuant to one or more valid orders placed in compliance with the terms of this Agreement, which failure continues for a period of [**] days; (iv) Moss fails, for any reason, including an event of force majeure, to deliver Products which conform to the applicable specifications, which failure is not corrected within [**] days after notice thereof; or (v) any other event occurs, including an event of force majeure, which renders Moss incapable of supplying Product to IDEXX pursuant to this Agreement if it reasonably foreseeable that such inability shall continue for [**] days or more.  Upon the occurrence of any of the triggering events described above, IDEXX agrees to use Moss’ manufacturing information only for its own internal purposes and to utilize strict security measures to keep such information confidential.

In the event that a triggering event occurs and IDEXX commences manufacture of the Products as set forth above, IDEXX shall pay Moss a royalty of [**]% of the price per Product set forth on Schedule B.  Further, in the event that a triggering event occurs and IDEXX commences manufacture of the Products as set forth above, Moss shall make its employees available to IDEXX, at IDEXX’s expense, to assist IDEXX with its commencement of manufacturing the Product, under the condition that those Moss employees are not involved in manufacturing the Products at Moss’s facilities.  If and when Moss regains its ability to manufacture IDEXX’s requirements of the Products, IDEXX shall cease manufacturing the Products for itself, shall destroy all copies of such manufacturing documents (whether in hard copy or electronic form) and shall return Moss’ original manufacturing documents into escrow with the Escrow Agent and provide Moss with written certification that it has done so.  In addition, if and when Moss regains its ability to manufacture IDEXX’s requirements of the Products, Moss shall purchase from IDEXX, at cost, all of the unused raw materials that IDEXX purchased to manufacture the Products, provided however that Moss shall not be required to purchase any amounts of raw materials in excess of those necessary to create [**] liters of the Product.  All unused raw materials that are purchased by Moss from IDEXX must meet Moss’s raw materials specifications.  If the raw materials to be purchased do not meet Moss’s specifications, Moss will not be required to purchase such raw materials.

Upon termination or expiration of this Agreement, the Escrow Agent shall return all of Moss’ manufacturing documents to Moss, or at Moss’ request, the Escrow Agent shall destroy such information and certify to Moss in writing that it has done so.

WARRANTY: Moss warrants to IDEXX that it shall produce the Products in conformity to the specifications set forth on the attached Schedule A.  In the event that any Products delivered to IDEXX do not, conform to such specifications, Moss agrees to replace such Products at no cost to IDEXX.

Throughout the term of this Agreement, Moss shall maintain commercial general liability insurance covering Moss’activities under this Agreement, with a coverage limit of not less than US $[**] million Moss shall provide IDEXX with a certificate evidencing its respective insurance coverages as IDEXX shall request from time to time.

MISCELLANEOUS: This Agreement shall be governed by the laws of the State of (Maryland) and cannot be modified except in writing signed by authorized representatives of both parties.

This Agreement, which includes the confidential disclosure agreements previously signed by the parties on March 1, 2001 (the term of which extends through 2026 and which is unaffected by this Agreement) constitutes the entire agreement between the parties with respect to the subject matter hereof and, other than as set forth herein to the contrary, supersedes all prior agreements and negotiations relating to the subject matter hereof.

If any provision of this Agreement is held by a court of competent jurisdiction to be unenforceable because it is invalid or in conflict with any law of any relevant jurisdiction, the validity of the remaining provisions shall not be affected.

Any controversy or claim arising out of or relating to this agreement, or the breach thereof, shall be settled by arbitration conducted in the state of Maryland and administered by the American Arbitration Association under its Commercial Arbitration Rules, and judgment on the award rendered by the arbitrator(s) may be entered in any court having jurisdiction thereof.

The waiver by either party of a breach or a default of any provision of this Agreement by the other party shall not be construed as a waiver of any succeeding breach or default of the same or any other provision, nor shall any delay or omission on the part of either party to exercise or avail itself of any right, power or privilege that it has or may have hereunder operated as a waiver of any right, power or privilege by such party.
