Recitals

Whereas, AOI develops, manufactures and sells, among other things, ***** optical transceivers; and

Whereas the Parties wish to enter into this Agreement in order for AOI to allocate a forecasted volume of products that AOI is to supply to Facebook in accordance with the terms of this Agreement.

1. 2018 Volume/Capacity Planning

A. Forecasts. Facebook will use commercially reasonable efforts to provide accurate 6 month rolling forecasts to AOI, identifying Facebook’s potential future product needs and delivery expectations on calendar quarter basis (“Forecasts”). Unless otherwise specified in this Agreement, such Forecasts are for planning purposes, are non-binding, and shall not constitute an order or purchase.

B. Supply and Purchase Commitment. Table 1 below in this section sets forth AOI’s ***** optical transceiver quantity of product that AOI will supply by Facebook’s deployment quarter and per delivery date as set forth on Authorized Buyer’s purchase order for calendar year (CY) 2018, and covers all volumes for Facebook and Facebook’s VAR partners procuring on Facebook’s behalf (“Authorized Buyers”). Accordingly, Facebook agrees to purchase (or, as applicable, have purchased and received on its behalf by an Authorized Buyer), and AOI agrees to allocate to Facebook (or, as applicable, it’s Authorized Buyers), the total quarterly amount of product in units to meet Facebook’s deployment schedule. All purchases by Facebook will be subject to Facebook Purchase Order Terms and Conditions, or a superseding Master Purchase Agreement between the Parties, and all purchases by an Authorized Buyer will be subject to the existing agreements with the applicable Authorized Buyer.

C. Supply Flexibility Commitment. AOI agrees to support up to ***** incremental supply flexibility within each calendar quarter, based on the quarterly committed volume as reflected in table 1. Upside material that is not consumed within the given quarter will be considered available supply for AOI to release as appropriate, after review and agreement with FB. Additional upside greater than ***** will be reasonably evaluated for potential support based on AOI’s standard lead-time.

D. Unit Growth. For CY 2019 and CY 2020 Facebook is forecasting AOI production volumes equivalent to the larger of ***** units (*****) or ***** percent (*****%) of Facebook’s total product requirements, i.e. Facebook TAM. Facebook demand forecasts for the subsequent year will be provided to AOI in third calendar quarter of the current CY. For purpose of clarity, Facebook will provide AOI its actual demand forecast for CY 2019 by *****, and the parties will finalize the actual CY 2019 support and purchase commitment by *****.

E. Product Qualification; Shortfalls; Forecast Changes.

1. AOI’s products must be qualified at Facebook in advance of the delivery calendar quarter in Table 1 to be eligible for purchase. In the event that Facebook has not completed qualification of the new product revision, AOI will continue to provide the previous product version until either Facebook qualification has been completed the last time ship date in the product change notification has passed, whichever comes first. AOI agrees to provide product change notification documentation not less than 6 months from the last time buy date. The qualification status of a specific product will be determined by AOI and Facebook (or Authorized Buyers) before acceptance of purchase orders. This list of qualified parts will be maintained by AOI and relevant Authorized Buyers.

2. In the event that Facebook and its Authorized Buyers fall short of purchasing the quarterly product volume as set forth in Table 1, Facebook will purchase the balance of committed demand at the end of each respective quarter at the unit price agreed for the shortfall quarter pursuant to the table in Table 2.

3. Notwithstanding any language to the contrary, in the event that AOI fails to meet quarterly delivery requirements stated in Table 1 by a percentage of *****, AOI will be subject to order cancellation by Facebook with reduced net quarterly consumption overall and cost to cover payment penalties.

4. In such case a Force Majeure event causes AOI to fall short of supplying a quarterly allocation in accordance with Section 1.B, Facebook, in its sole discretion, has the option to move the shortfall allocation amount into a subsequent quarter or to reduce the overall purchase commitment by an amount equal to the shortfall. For purpose of clarity, a Force Majeure event is the only event that will delay or excuse AOI obligation to meet its quarterly shipment commitment.

5. Facebook can request delivery changes by site as set forth in Table 1 beyond a ***** rolling window. AOI will use commercially reasonable efforts to accept the requested change(s).

2. Pricing

A. The Parties agree to the negotiated quarterly price for the product, based on the 2018 RFQ and as shown in the table below.
