Asterisks denote omissions. 3.2 Royalties. In further consideration of the rights, privileges and licenses granted by IMMULOGIC hereunder, HESKA shall pay royalties as follows: (a) Veterinary Field. With respect to Patented Products sold in the Veterinary Field, royalties calculated as a percentage of quarterly Net Sales, as follows: (A) Net Sales in the Veterinary Field for gene therapy or allergy prophylaxis applications [**] (B) Net Sales in the Veterinary Field for diagnostic or standard immunotherapy applications: - First [**] million of such Net Sales in the Veterinary Field [**] - Such Net Sales in excess of [**] million up to [**] million in the Veterinary Field [**] - Such Net Sales in excess of [**] million in the Veterinary Field [**] (b) Human Field. Subject to Section 3.2(c) below, with respect to Patented Products sold in the Human Field, royalties calculated as a percentage of quarterly Net Sales as follows: (A) Net Sales in the Human Field for gene therapy or allergy prophylaxis applications [**] (B) Net Sales in the Human Field for diagnostic or standard immunotherapy applications: - First [**] million of such Net Sales in the Human Field [**] - Such Net Sales in excess of [**] million up to [**] million in the Human Field [**] - Such Net Sales in excess of [**] million in the Human Field [**] -7- 8 Confidential Materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions. (c) Sublicense in Human Field. Notwithstanding the foregoing, if HESKA sublicenses its rights to the Licensed Technology under this Agreement with respect to diagnostic products, therapeutic products or both (as applicable, the "Sublicensed Products") in the Human Field to one or more sublicensees (collectively, a "Human Field Sublicensee") in one or more countries (each, a "Territory'"), then HESKA shall make payments to IMMULOGIC pursuant to this Section 3.2(c) ("In Lieu Payments"), in lieu of (i) all royalties otherwise payable pursuant to Section 3.2(b) with respect to Net Sales of Sublicensed Products in such Territory and (ii) the Pro Rata License Fee (as defined below) applicable to such Territory otherwise payable pursuant to Section 3.1(b). The parties shall negotiate in good faith to pro rate any milestone license fees provided in Section 3.1(b) not previously earned by IMMULOGIC between any such Human Field Sublicensee's Territory and HESKA's other markets for Licensed Products, based on the relative size of such markets, and the amount so determined shall be the "Pro Rata License Fee." In the case of each sublicense to Human Field Sublicensee(s), the In Lieu Payment shall be an amount equal to [**] of each license fee, milestone payment or royalty payment received by HESKA from such Human Field Sublicensee pursuant to such sublicense(s) for exploitation of the Licensed Technology with respect to Sublicensed Products in the Human Field in the Territory. 3.3 Combination Products; Services. When any Patented Products are sold in combination with other allergens or other products for a single unit price, Net Sales for such Patented Products shall be an amount equal to a percentage of the unit price determined by dividing the number of individual allergens included in the combined product that constitute Patented Products by the total number of individual allergens included in the combined product, adjusted as set forth in Section 1.11. If any Patented Products are utilized in connection with diagnostic or testing services performed for compensation by HESKA, its Affiliates or Sublicensees, Net Sales for such Patented Products shall be an amount equal to a percentage of the total compensation for such service, determined by dividing the number of individual allergens utilized in the service that constitute Biological Materials by the total number of individual allergens utilized in the service, after the adjustments set forth in Section 1.11 and deduction of HESKA's direct labor cost for such diagnostic services. 3.4 Third Party Royalties. (a) Stacking. If HESKA, its Affiliates or Sublicensees are required to pay royalties to third parties on sales of Patented Products in order to use any process or composition of matter other than the Licensed Technology to develop, have developed, make, have made, use, sell, have sold or otherwise exploit Licensed -8- 9 Confidential Materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions. Products in any country, and the resulting aggregate royalty rate is [**] or greater, then the royalty rate under Section 3.2 above will be adjusted so that the combined royalty payments from HESKA to all of its licensors, including IMMULOGIC, does not exceed [**] (assuming that such adjustment is also applied to all third party royalty rates). The royalty rate payable to IMMULOGIC would be reduced to a rate determined by multiplying the royalty rate under Section 3.2 above by a fraction, the numerator of which is [**] and the denominator of which is the aggregate royalty rate. For example, if the aggregate royalty rate was [**] the new royalty rate payable to IMMULOGIC would be determined by multiplying the royalty rate under Section 3.2 above by [**]. Notwithstanding the foregoing, if HESKA's agreement with any of such other licensors provides for a royalty proration formula based on an aggregate royalty rate of greater than [**], the parties will substitute such greater aggregate royalty rate for the [**] rate set forth in this Section 3.4. (b) Freedom to Operate. If HESKA, its Affiliates or Sublicensees are required to pay royalties to third parties on sales of Licensed Products in order to have the right to use any of the Licensed Technology to develop, have developed, make, have made, use, sell, have sold or otherwise exploit Licensed Products in any country, then HESKA shall have the right to credit [**] of such third party royalty payments against (i) any royalties or other payments otherwise owing to IMMULOGIC under Section 3.2 with respect to sales of such Licensed Products in such country and (ii) any milestone license fees otherwise owing to IMMULOGIC under Section 3.1(b). HESKA's offset rights pursuant to this paragraph are in addition to its indemnification rights pursuant to Article 7 of this Agreement. (c) Procedure for Adjustments. In any case where both Section 3.4(a) and (b) apply, the royalty rates payable to IMMULOGIC shall first be adjusted pursuant to Section 3.4(a) and then adjusted again as provided in Section 3.4(b). -9- 10 ARTICLE 4. - REPORTS; PAYMENT 4.1 Royalty Reports; Payment. During the term of the Agreement, HESKA shall furnish to IMMULOGIC a quarterly written report calculating in reasonably specific detail the royalties and other payments payable, if any, for such quarter pursuant to this Agreement.
