NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Supplier and Purchaser hereby agree as follows:

1.                                       Commitment of Purchaser.  Purchaser agrees during the Term (as defined below) that Purchaser will purchase one hundred percent (100%) of Purchaser’s Products needs for the manufacture of 10% Bulk Iron Dextran solution exclusively from Supplier; provided, however, that Purchaser shall be obligated to purchase Products exclusively from Suppler only so long as:

(b)                                 Supplier is not in material breach of this Agreement, which breach continues uncured in excess of thirty (30) days following the date written notice reasonably describing such breach is delivered by Purchaser to Supplier pursuant to the terms hereof.

2.                                       Commitment of Supplier.  Supplier agrees during the Term that Supplier will sell Products in the United States of America for use in producing 10% Bulk Iron Dextran solution for veterinary use exclusively to Purchaser; provided, however, that Supplier will be obligated to refrain from selling Products in the United States of America for use in producing 10% Bulk Iron Dextran solution for veterinary use to any person or entity other than Purchaser only so long as:

(a)                                  Purchaser purchases no less than XXXX^* kilograms of Ferric Hydroxide and XXXX* kilograms of Hydrogenated Dextran solution every two (2) calendar quarters (each, a “Purchase Period”) during the Term; provided, however, that this condition (a) shall not apply if Supplier materially fails to fill Purchaser’s orders for Ferric Hydroxide and Hydrogenated Dextran solution with Products meeting the product specification set forth on Schedule 1 hereto; and

(b)                                 Purchaser is not in material breach of this Agreement, which breach continues uncured in excess of thirty (30) days following the date written notice reasonably describing such breach is delivered by Supplier to Purchaser pursuant to the terms hereof.

(c)                                  During the Term of this Agreement, Purchaser shall pay to Supplier US$XXXX* per kilogram, dry basis, of Iron supplied as a Ferric Hydroxide solution and US$XXXX* per kilogram, dry basis, of Dextran supplied as a Hydrogenated Dextran solution (each such amount is referred to as the “Base Price”); provided, however, that during the second and each subsequent year of this Agreement, Supplier may increase the Base Price for each Product, not to exceed more than XXXX* percent (XX*%) per annum, solely for XXXX* as reasonably documented by written evidence provided by Supplier to Purchaser.

(d)                                 During years 6-10 of this Agreement, Supplier may add to the Base Price of each Product (as calculated pursuant to paragraph (c) above) a surcharge (the “Surcharge”) as set forth below:

XXXX*

The foregoing Surcharges apply during each specified year, but are not cumulative.

(e)                                  During years 1-5 of this Agreement, the “Price” for each Product shall be the Base Price calculated as set forth in paragraph (c) above.  During years 6-10 of this Agreement, the “Price” for each Product shall be the sum of the Base Price calculated as set forth in paragraph (c) above plus the Surcharge for such year as set forth in paragraph (d) above.

(f)                                    Purchaser shall pay the Price for each Order of Products set forth in the invoice delivered by Supplier to Purchaser with respect thereto within thirty (30) days after invoice date (which shall be no earlier than the date the Products are received by Purchaser) of such Product, unless otherwise agreed to in writing by the parties hereto.

(g)                                 Except as provided in Section 4(b) below, any national, state, provincial, county or municipal sales or use tax, excise, or similar charge or any other tax assessment, license, fee or other charge assessed or charged in the sale of Products sold to Purchaser by Supplier pursuant to this Agreement shall be the responsibility of Purchaser, and shall be paid by Purchaser to Supplier with respect to each Order of Product in addition to the Price.

(iii)                               This Agreement is executed by the parties with full knowledge of their respective termination rights hereunder.  No party hereto shall be liable to any other party for compensation, reimbursement for investments or expenses, lost profits, incidental or consequential damages, or damages of any other kind or character, because of any exercise of such rights.
