In consideration of the mutual promises and covenants set forth in this Agreement, the parties agree as follows:

Orders for Products

1.1

Products. Subject to the terms and conditions of this Agreement, Seller will sell to Customer, and Customer will purchase from Seller, the products listed in Exhibit A (“Products”). A revision will apply to all orders accepted after the effective date of the revision. Seller understands that Customer may resell certain Products to end customers (“End Customers”). Customer will be responsible for the marketing and sale of re-sold Products to End Customers; Seller will be responsible for shipping and delivery to Customer in accordance with this Agreement.

1.2

Powder Specifications. Seller and Customer have mutually agreed upon and accepted specifications for the Products (“Powder Specifications”) that are attached in Addendum C. Customer may propose modifications to the Powder Specifications upon written notice to Seller. Seller shall have five (5) business days from receipt of such notice to review the proposed modifications and notify Customer in writing of its acceptance or rejection. If Seller accepts the proposed modifications (or fails to respond within such five (5) day period), such modifications shall become effective: (a) the latter date of forty-five (45) days after Seller’s receipt of Grade 5 bar feedstock or forty-five (45) days after Seller’s acceptance (or the expiration of the review period) for any changes affecting Grade 5 titanium specifications; and (b) thirty (30) days after Seller’s acceptance (or the expiration of the review period) for all other specification changes. If Seller rejects the proposed modifications, the parties shall negotiate in good faith to reach a mutually acceptable resolution.

1.3

Term and Conditions of Sale. The terms and conditions of this Agreement will control all sales of Products by Seller to Customer, and any conflicting or additional terms contained in any Customer purchase orders or other documents are hereby specifically objected to and will be of no effect.

1.4

Order Submission by Customer

(a)

Purchase Orders. Customer will order Products by submitting written purchase orders that set forth the details for the ordered Products (i.e., type and quantity ordered, delivery destination, requested shipment date). This Agreement will serve as a Purchase Order for the Minimum Commitment of Products as described in Exhibit A and Customer may order additional Products by submitting additional Purchase Orders to Seller (“Additional Purchase Orders”). Additional Purchase Orders must be placed in accordance with the lead-time restrictions in Section 1.4(b). Any terms of a Purchase Order that conflict with, or in any way purport to amend, any of the terms of this Agreement are hereby specifically objected to and will be of no effect.

(b)

Minimum Order Lead-time. Customer will provide Seller with a minimum order lead-time (i.e., the time between receipt of an Additional Purchase Order by Seller and the requested Product shipment date) for the shipment of Products of no less than four weeks. For those Additional Purchase Orders for which Customer fails to provide the minimum order lead-time, Seller will not be obligated to accept the Additional Purchase Order, but if Seller does accept the Additional Purchase Order, Seller will use reasonable efforts to fill the Additional Purchase Order by the shipment date requested by Customer.

1.5

Review of Additional Purchase Orders by Seller. No later than three business days after receipt of an Additional Purchase Order, Seller will advise Customer in a written or electronic notice whether it has accepted the Additional Purchase Order (“Order Acknowledgement”). If Seller fails to deliver an Order Acknowledgement within the three business day period, the Additional Purchase Order will be deemed rejected. Seller reserves the right to accept Additional Purchase Orders in its reasonable discretion, provided that Seller will use commercially reasonable efforts to accept any such Additional Purchase Orders and deliver the applicable Products within 4 weeks of the date of the Accepted Purchase Order. Seller may not cancel any previously accepted Additional Purchase Order except for Customer’s material breach of this Agreement that remains uncured following 30 days’ written notice.

1.6

Accepted Orders. For the purposes of this Agreement, an “Accepted Order” is an order described in (a) this Agreement (when relating to Purchase Orders for Minimum Commitments); or (b) an Order Acknowledgement delivered by Seller in accordance with Section 1.5.

1.7

Minimum Commitment and Purchasing Amounts. Customer agrees to purchase Products in at least the quantities specified as the Minimum Commitments in Exhibit A. The shipping, delivery, and purchasing terms for the Minimum Commitments will be as described in Exhibit A. Seller agrees to prioritize production for additional Customer orders of Products up to a 100% increase from the applicable Minimum Commitment. Any Additional Purchase Orders for quantities above this amount may be accepted or rejected in Seller’s sole discretion. Notwithstanding the foregoing, if Seller delivers Nonconforming Products, Customer provides notice to Seller in accordance with Section 2.5 of this Agreement, Seller fails to replace such Nonconforming Products within the time periods set forth therein, and as a direct and substantiated result thereof an End Customer cancels a contract with Customer, Customer may reduce the applicable Minimum Commitment by the quantity of Products attributable to such canceled contract without any corresponding adjustment to the per-unit pricing set forth in Exhibit A.

Accepted Orders for Products

2.1

Delivery. The Products will be delivered as specified in the Accepted Purchase Order, subject to availability of finished Products. Seller shall not be liable for any delays, loss, or damage in transit. Unless otherwise agreed in writing by the parties, Seller shall deliver the Products to Customer’s loading dock (the “Delivery Point”) using Seller’s standard methods for packaging and shipping such Products. Customer shall take delivery of the Products immediately upon delivery to the Delivery Point. Customer shall be responsible for all loading costs and provide equipment and labor reasonably suited for receipt of the Products at Customer’s receiving location. Seller may, with Customer’s consent, make partial shipments of Products to Customer.

Each shipment will constitute a separate sale, and Customer shall pay for the units shipped whether such shipment is in whole or partial (if Customer consented) fulfillment of the Accepted Purchase Order. If for any reason Customer fails to accept delivery of any of the Products that have been delivered Customer’s receiving location, or if Seller is unable to deliver the Products at the Delivery Point on such date because Customer has not provided appropriate instructions, documents, licenses or authorizations: (i) risk of loss to the Products shall pass to Customer; (ii) the Products shall be deemed to have been delivered; and (iii) Seller, at its option, may store the Products until Customer picks them up, whereupon Customer shall be liable for all related costs and expenses (including, without limitation, storage and insurance costs).

2.2

Non-Delivery. The quantity of any installment of Products as recorded by Seller on dispatch from Seller’s place of business is evidence of the quantity received by Customer on delivery unless Customer can provide conclusive evidence proving the contrary. The Seller shall not be liable for any non-delivery of Products (even if caused by Seller’s negligence) unless Customer gives written notice to Seller of the non-delivery within five (5) business days of the date when the Products would in the ordinary course of events have been received. Any liability of Seller for non-delivery of the Products shall be limited to replacing the Products within a reasonable time or adjusting the invoice respecting such Products to reflect the actual quantity delivered.

2.3

Shipping and Packaging Terms. Seller shall make delivery in accordance with the terms on the face of the Accepted Purchase Order. Customer will supply, at Customer’s sole expense, packaging materials for the Products in the form of 6 Liter CurTec containers, liner bags and other packaging materials. Customer will maintain a minimum of 30 days supplies of such packaging materials to be stored on premise at Seller at all times during the term of this Agreement.

2.4

Title and Risk of Loss. Title and risk of loss pass to Customer upon delivery of the Products at the Delivery Point. As collateral security for the payment of the purchase price of the Products, Customer hereby grants to Seller a lien on and security interest in and to all of the right, title, and interest of Customer in, to, and under the Products, wherever located, and whether now existing or hereafter arising or acquired from time to time, and in all accessions thereto and replacements or modifications thereof, as well as all proceeds (including insurance proceeds) of the foregoing. The security interest granted under this provision constitutes a purchase money security interest under the Tennessee Uniform Commercial Code.

2.5

Inspection and Rejection of Nonconforming Products. Customer shall inspect the Products within five (5) days of receipt (“Inspection Period”). Customer will be deemed to have accepted the Products unless it notifies Seller in writing of any Nonconforming Products during the Inspection Period and furnishes such written evidence or other documentation as reasonably required by Seller; provided, however, that with respect to Nonconforming Products that are not reasonably discoverable by Customer during the Inspection Period but are subsequently identified through inspection or testing by an End Customer, Customer shall notify Seller in writing within five (5) business days of receiving written notice from such End Customer, together with such supporting documentation as may be reasonably available. “Nonconforming Products” means only the following: (i) product shipped is different than identified in the Accepted Purchase Order; (ii) product’s label or packaging incorrectly identifies its contents; or (iii) product does not conform to the Powder Specifications. If Customer timely notifies Seller of any Nonconforming

Products, Seller shall, in its sole discretion, (i) replace such Nonconforming Products with conforming Products, or (ii) credit or refund the Price for such Nonconforming Products. Seller shall be responsible for all shipping and handling expenses incurred by Customer in connection with returning Nonconforming Products and receiving replacement Products. If Seller exercises its option to replace Nonconforming Products, Seller shall, after receiving Customer’s shipment of Nonconforming Products, ship to Customer, at Customer’s expense and risk of loss, the replaced Products to the Delivery Point. Customer acknowledges and agrees that the remedies set forth herein are Customer’s exclusive remedies for the delivery of Nonconforming Products. Except as provided herein, all sales of Products to Customer are made on a one-way basis and Customer has no right to return Products purchased under this Agreement to Seller; provided, further, that this limitation shall not apply to Nonconforming Products identified by End Customers pursuant to this Section, for which Customer shall retain the right to return such Products to Seller in accordance with the procedures set forth above.

Exhibit A to the Agreement is hereby amended and restated as follows:

EXHIBIT A

Products, Minimum Commitments, and Pricing.

9.1

Product: Ti-6AI-4V Grade 23 powder, as amended, in two (2) classifications:
