THIS MANUFACTURING SERVICES AGREEMENT (the “Agreement ) is made effective as of November 3, 2010 (the “Effective Date”) between PRECISION ONE MEDICAL, INC., a California corporation, on behalf of itself and its affiliates, (“Manufacturer”), and BIOHORIZONS, INC. a Delaware corporation having a place of business at 2300 Riverchase Center, Birmingham, AL 35244, on behalf of itself and its affiliates, (“BioHorizons” and together with Manufacturer, the “Parties”).  Capitalized terms used herein without definition shall have the respective meanings ascribed thereto in Section 10.

WHEREAS, BioHorizons desires Manufacturer to manufacture, assemble and supply the Products for purchase by BioHorizons; and

WHEREAS, Manufacturer desires to manufacture, assemble and supply the Products for sale to BioHorizons, all as further set forth herein;

NOW, THEREFORE, for good and valuable consideration,

the receipt and sufficiency of which is hereby acknowledged, the Parties agree as follows:

Section 1.               Manufacture and Supply of Products.

(a)           Requirements; Manufacture of Products.  During the Term and subject to the terms and conditions set forth herein, (i) Manufacturer shall manufacture and supply all of BioHorizons’s requirements of Products, and (ii) except as otherwise provided herein, BioHorizons shall purchase all of its requirement for Products exclusively from Manufacturer, including Products for studies, demonstration/sample purposes and commercial sale.

(b)           Forecasts.  From time to time BioHorizons shall furnish Manufacturer with a good faith estimate of the quantities of each Product that BioHorizons intends to purchase from Manufacturer during the average month of the upcoming four (4) calendar quarters (the “Forecast”).  The initial forecast as of the Effective Date is attached as Exhibit A.  Notwithstanding the foregoing, BioHorizons shall notify Manufacturer of any revision to a Forecast already furnished to Manufacturer as soon as commercially practicable after BioHorizons becomes aware that its likely or actual requirements for one or more Products have materially changed.  It is understood that the quantities specified in the Forecasts are intended to be estimates only and shall not be binding on BioHorizons.

(c)           Orders.  BioHorizons shall make all purchases by submitting purchase orders to Manufacturer which shall be firm and binding.  Each purchase order shall specify the quantity of each Product ordered by item number.  BioHorizons will use commercially reasonable efforts to place purchase orders [***] prior to their required delivery date.

(i)            To the extent the quantity of Products ordered is consistent with the applicable Forecast or within the inventory maintained by Manufacturer in accordance with Section 1(i) (a “Qualifying Order”) Manufacturer shall deliver the ordered Products on the schedule specified in the purchase order.

Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 406 of the Securities Act of 1933, as amended.

(ii)           Manufacturer shall notify BioHorizons within [***] ([***]) [***] after receipt of a purchase order that is not a Qualifying Order if Manufacturer is unable to deliver such excess quantity within the time period specified in the purchase order, and the Parties will work together in good faith to enable Manufacturer to meet the terms of the order as closely as possible.

(iii)          Manufacturer shall use commercially reasonable efforts to fill purchase orders issued by BioHorizons that are not Qualifying Orders.

(d)           Price.  Unless modified pursuant to the provisions of this Agreement or otherwise agreed in writing by both Parties, the price for each Product shall be as set forth on Exhibit A.

(e)           Supply.  Manufacturer shall supply the Products in accordance with the Specifications then in effect.  Manufacturer shall manufacture the Products in compliance with cGMP and applicable Quality Standards.

(f)            Delivery.  All Products delivered to BioHorizons shall be FCA (INCOTERMS 2000) Manufacturer’s facility.  Manufacturer shall deliver ordered Products within the time frame agreed to by the Parties.  BioHorizons shall arrange all insurance and transportation as specified in writing from time to time by BioHorizons.  Manufacturer shall package the Products in accordance with their Packaging Specifications.  Manufacturer will (i) retain all original quality and testing records, which shall be in a form reasonably acceptable for submission to all applicable Regulatory Authorities and shall be available for inspection by BioHorizons from time to time upon reasonable notice to Manufacturer, and (ii) include with each shipment copies of all applicable quality and testing records and a Certificate of Conformity signed by a Manufacturer administrator with authority to bind Manufacturer that manufacture was in accordance with applicable Quality Standards and that the Products conform to the Specifications and have been packaged in conformance with the Packaging Specifications.

(g)           Rejection of Product in Case of Nonconformity.

(i)            Within [***] ([***]) [***] of receipt of any shipment of Products, BioHorizons may reject any portion of such shipment which is (a) not conforming to the Specifications or Packaging Specifications, (b) damaged during shipment as a result of Manufacturer having not packaged the Products in conformance with the Packaging Specifications or (c) adulterated or misbranded within the meaning of the Federal Food, Drug and Cosmetic Act (the “Act”) or any similar provisions of any other Applicable Law.  If no notice of intent to reject is timely received by Manufacturer, BioHorizons shall be deemed to have accepted such delivery of Products; provided, however, in the case of Products having latent defects which upon visual examination, without opening the packaging, by BioHorizons upon receipt could not reasonably have been discovered, BioHorizons must give notice of BioHorizons’s intent to reject within [***] ([***]) [***] after discovery of such defects; provided that such notice may in no event be given later than [***] ([***]) [***] after the earlier of (a) [***] ([***]) [***] from the delivery date, and (b) the expiration date on the label of such Product.

Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 406 of the Securities Act of 1933, as amended.

(ii)           In order to reject a shipment, BioHorizons must (a) give notice to Manufacturer of BioHorizons’s intent to reject the shipment within [***] ([***]) [***] of receipt together with a written indication of the reasons for such rejection, and (b) as promptly as commercially reasonable thereafter, provide Manufacturer with notice of final rejection and the full basis therefor.

(iii)          Manufacturer shall replace as soon as reasonably practicable and at its cost, including shipping and insurance, all Products that have been properly rejected by BioHorizons.

(h)           Product Warranty.  Manufacturer represents and warrants to BioHorizons that at the time of delivery to BioHorizons the Products will: (i) be new and conform in all respects to the Specifications in effect at the time of shipment; (ii) have been manufactured in accordance with the Quality Agreement and in accordance with the Quality Standards and all other Applicable Law; (iii) be packaged in accordance with the Packaging Specifications in effect at the time of shipment, (iv) not be adulterated or misbranded within the meaning of the Act, and (v) be free and clear of any and all liens and encumbrances of whatsoever nature and kind.  Manufacturer further represents and warrants that the Products will be free from all defects in workmanship and materials at the time of delivery to BioHorizons and for the period from the date of delivery until the earlier of (a) the expiration date on the labels of the Products, and (b) [***] ([***]) [***] from the date of delivery of the Products, provided that the Products are stored under the conditions stated on their labels.

(i)            Inventory.  Manufacturer shall manufacture and maintain on hand at all times during the Term a two (2) month inventory for each item number included on the list of Products included on Exhibit A.  Within [***] ([***]) [***] of receipt of any Forecast that requires a material increase in the amount of inventory required to be maintained by Manufacturer pursuant to this Section, Manufacturer shall maintain, for each item number included on the list of Products (as updated by such Forecast), the lesser of (i) [***]% of the number of parts purchased by BioHorizons during the previous twelve (12) calendar months or (ii) a [***] ([***]) [***] supply based on such Forecast.

(j)            Liquidated Damages.  The Parties acknowledge and agree that the delivery of the Products by Manufacturer is one step in a multi-part supply chain and that any delay in delivery of Products will require BioHorizons to revise schedules with multiple other vendors, pay for expedited handling and undertake other actions that will be costly and distracting and could harm relations between BioHorizons and its vendors, customers and distributors.  The Parties acknowledge and agree that it would be impracticable and extremely difficult to ascertain the amount of actual damages caused by the occurrence of a breach of Section 1(c)(i) and that the amount of damages sustained by BioHorizons would generally be proportionate to the value of the order that is not timely filled.  Therefore, the Parties agree that upon the occurrence of a breach of Section 1(c)(i), Manufacturer shall credit BioHorizons, as liquidated damages and not as a penalty, an amount equal to the product of (x) [***]% of the invoice price of Late Parts and (y) the number of days elapsed between the date of receipt of a Late Notice and the date of delivery of the Late Parts, but in no case to exceed [***]%.  The Parties further agree that this liquidated damages provision represents reasonable compensation for the loss which would be incurred by BioHorizons due to any such breach.

Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 406 of the Securities Act of 1933, as amended.

(k)           Priority.  Orders for Products, whenever received, will have priority over orders from any other customer of Manufacturer, whenever received.  Manufacturer will change the priority of manufacture of Products as requested by BioHorizons without any additional charge to BioHorizons.

(l)            Location of Manufacture.  Manufacturer shall manufacture the Products only in the United States unless the manufacture of Products elsewhere is authorized in writing by BioHorizons in its sole discretion.

(m)          Exclusivity.  Manufacturer shall be the exclusive supplier of Products to BioHorizons during the Term, except as provided in Section 1(n).

(n)           Alternative Manufacturing.  Notwithstanding anything to the contrary herein, BioHorizons shall have the right, in its sole discretion, to have part of its requirements for the Products manufactured by itself or third parties if in the good faith judgment of BioHorizons having a second source is reasonably required in order to maintain an appropriate supply chain.

(o)           Payment Terms.  Manufacturer will issue one invoice for each purchase order.  All payments to Manufacturer under this Agreement are to be made in US dollars and shall be paid within forty-five (45) days of invoice, which Manufacturer shall issue, as applicable, monthly or when or after it ships the Products to BioHorizons or its designee.  Interest at a monthly rate of one percent (1%) shall accrue on all payments that are not the subject of a dispute in good faith and are not made within the aforementioned forty-five (45) day period.

(p)           Specification Changes.

(i)            In the event that BioHorizons changes any Specifications, then the Parties will negotiate any appropriate change in pricing based on such changes.  In the event that the Parties cannot agree on revised pricing, BioHorizons shall be relieved of its obligation pursuant to Section 1(m).

(ii)           In the event that BioHorizons changes any Specifications such that inventory stored at Manufacturer’s facility pursuant to (i) becomes obsolete, then within ninety (90) days of the date BioHorizons notified Manufacturer of such change, BioHorizons will (x) order any Products that were finished product stored at Manufacturer’s facility pursuant to (i) or (y) pay Manufacturer for such Products and request that Manufacturer discard or destroy such Products at no charge to BioHorizons.  With respect to any Products that were work in progress based on a purchase order or compliance with (i) on the date BioHorizons notified Manufacturer of such change, BioHorizons will make payment, within ninety (90) days of the date BioHorizons notified Manufacturer of such change, of the price of such Products less a discount to be determined in good faith by Manufacturer based on its cost savings from not having to finish such Products.  BioHorizons will notify manufacturer of its decision to have Manufacturer deliver such work in progress to BioHorizons or have Manufacturer discard or destroy such Products at no charge to BioHorizons.

(iii)          In no event will BioHorizons be liable to Manufacturer pursuant to this Section 1(p) for inventory in excess of the sum of (x) the minimum required to be maintained by

Manufacturer in accordance with Section 1(i) plus (y) the amount subject to an open purchase order at the time of the Specification change.

Section 2.               Benchmarking.

(a)           At any time or from time to time, but not more than [***] ([***]) times in any calendar year, BioHorizons may benchmark the prices, service levels, and processes offered by peer service providers in the industry to peer customers in the industry.

(b)           In the event that BioHorizons reasonably determines, with respect to one or more Products, that (a) BioHorizons could contract for materially more favorable service levels from a peer service provider at lower pricing as the then current pricing pursuant to this Agreement or (b) the then current pricing pursuant to this Agreement is materially less favorable to BioHorizons as compared to the fees available from peer service providers in the industry for substantially equivalent services, then BioHorizons shall notify Manufacturer in writing of the results of its benchmarking review (such notice, the “Benchmarking Notice”).

(c)           Manufacturer shall have [***] from the date of the Benchmarking Notice to provide a written response (the “Benchmarking Response”) to (i) propose revised service levels, (ii) propose revised pricing and/or (iii) set forth a description of the nature of any dispute with respect to the contents of the Benchmarking Notice in sufficient detail so as to enable BioHorizons to assess the merit of the dispute.

(d)           The Parties agree to work together collaboratively for a period of [***] from the date of the Benchmarking Response.  In the event that the Parties are unable or unwilling to reach agreement on actions to be taken to address the issues raised in the Benchmarking Notice, then BioHorizons may, in its sole discretion, be relieved of its obligations under Section 1(m).  All other provisions of this Agreement would continue without change.

(e)           Manufacturer will actively work to achieve reductions in its costs of manufacturing Products.  At least once per calendar year, manufacturer and BioHorizons will review the costs of manufacturing Products in a good faith effort to reduce such costs.  Any resulting savings will be shared equally by the Parties.

Section 3.               Intellectual Property.

(a)           Ownership.  As between the Parties, BioHorizons exclusively shall have all right, title and interest in any Inventions made or conceived or reduced to practice by BioHorizons or on behalf of BioHorizons by Manufacturer, or by the Parties jointly, in the course of performing this Agreement.
