For example, and

9

not by way of limitation, Inverness is not granting to OraSure a license outside of the Lateral Flow Field or outside of the Professional Market.

3.5.2 Notwithstanding anything to the contrary in this Agreement, any Product described in clause (c) of Section 1.14, clause (b)(iii) of Section 1.16, or clause (b)(iii) of Section 1.17 may not be (a) sold by OraSure to the third party that sold such Product to OraSure (or any Affiliate of such third party), or (b) sold or otherwise distributed by OraSure under the direct control of such third party (or any Affiliate of such third party).

The fees charged by such accounting firm shall be paid by Inverness; provided, however, if the audit discloses that the royalties payable by OraSure for such period are more than one hundred seven percent (107%) of the royalties actually paid for such period, then OraSure shall pay the reasonable fees and expenses charged by such accounting firm.

11

4.4.4 Inverness shall cause its accounting firm to retain all financial information subject to review under this Section 4.4 in strict confidence; provided, however, that OraSure shall have the right to require that such accounting firm, prior to conducting such audit, enter into an appropriate non-disclosure agreement with OraSure regarding such financial information. The accounting firm shall disclose to Inverness only whether the reports are correct or not and the amount of any discrepancy. No other information shall be shared. Inverness shall treat all such financial information as OraSure’s Confidential Information.

4.5 Payments.

4.5.1 Payment Terms. Royalties accrued by the end of each Quarterly Period shall be due and payable on the date such royalty report is due. Payment of royalties in whole or in part may be made in advance of such due date. All payments under this Agreement shall be made when due hereunder in U.S. dollars by transfer to an Inverness bank account as designated by Inverness. Any payments that are not paid on or before the date such payments are due under this Agreement shall bear interest at a rate equal to the lesser of one percent (1%) per month or the highest rate permitted by applicable law, including, notwithstanding the foregoing, interest on the payment for past sales owed pursuant to Section 4.1. Interest payable shall be calculated on a compound basis with a monthly compounding period from the date the payment was due until the date payment is received by Inverness.

4.5.2 Exchange Control. If at any time legal restrictions prevent the prompt remittance of part or all royalties with respect to any country where the Product is sold, OraSure shall have the right, in its sole discretion, to make such payments by depositing the amount thereof in local currency to Inverness’s account in a bank or other depository institution in such country. If the royalty rate specified in this Agreement should exceed the permissible rate established in any country, the royalty rate for sales in such country shall be adjusted to the highest legally permissible or government-approved rate.

4.5.3 Withholding Taxes. OraSure shall be entitled to deduct the amount of any withholding taxes, value-added taxes or other taxes, levies or charges with respect to such amounts, other than United States taxes, paid by OraSure or its Affiliates, or any taxes required to be withheld by OraSure or its Affiliates, to the extent OraSure or its Affiliates, pays to the appropriate governmental authority on behalf of Inverness such taxes, levies or charges. OraSure shall use reasonable efforts to minimize any such taxes, levies or charges required to be withheld on behalf of Inverness by OraSure or its Affiliates. OraSure promptly shall deliver to Inverness proof of payment of all such taxes, levies and other charges, together with copies of all communications from or with such governmental authority with respect thereto.

ARTICLE 5

CONFIDENTIALITY

5.1 Confidentiality. During the term of this Agreement and for a period of five (5) years following the expiration or earlier termination thereof, each party shall maintain in confidence the Confidential Information of the other party, shall not use or grant the use of the Confidential Information of the other party except as expressly permitted hereby, and shall not disclose the Confidential Information of the other party except on a need-to-know basis to such

12

party’s and its Affiliates’ directors, officers, employees and consultants, to the extent such disclosure is reasonably necessary in connection with such party’s activities as expressly authorized by this Agreement. To the extent that disclosure to any person is authorized by this Agreement, prior to disclosure, a party shall obtain written agreement of such person to hold in confidence and not disclose, use or grant the use of the Confidential Information of the other party except as expressly permitted under this Agreement. Each party shall notify the other party promptly upon discovery of any unauthorized use or disclosure of the other party’s Confidential Information.

5.2 Terms of Agreement. Neither party shall disclose any terms or conditions of this Agreement to any third party without the prior consent of the other party; provided, however, that a party may disclose the terms or conditions of this Agreement on a need-to-know basis, (a) to its legal and financial advisors to the extent such disclosure is reasonably necessary, and (b) to a third party in connection with (i) an equity investment in such party, (ii) a merger, consolidation or similar transaction by such party, or (iii) the sale of all or substantially all of the assets of such party to which this Agreement relates, provided in each case that such persons are bound by written confidentiality obligations or, in the case of professional advisers, ethical duties, respecting such disclosures in accordance with the terms of this Agreement. Notwithstanding the foregoing, prior to execution of this Agreement, the parties have agreed upon the substance of information that can be used to describe the terms and conditions of this transaction, and each party may disclose such information, as modified by mutual written agreement of the parties, without the consent of the other party.

5.3 Permitted Disclosures. The confidentiality obligations under this Article 5 shall not apply to the extent that a party is required to disclose information by applicable law, regulation or order of a governmental agency or a court of competent jurisdiction; provided, however, that such party shall (i) provide written notice thereof to the other party, consult with the other party with respect to such disclosure and provide the other party sufficient opportunity to object to any such disclosure or to request confidential treatment thereof and (ii) shall furnish only that portion of the information which is legally required.

ARTICLE 6

INDEMNIFICATION

6.1 By OraSure. OraSure shall indemnify and hold harmless Inverness from all losses, liabilities, damages and expenses (including reasonable attorneys’ fees and costs) resulting from any claims, demands, actions or other proceedings by any third party to the extent resulting from (a) any breach by OraSure of any representation, warranty or covenant under this Agreement, or (b) the gross negligence or willful misconduct of OraSure in the performance of its obligations or exercise of its rights under this Agreement, except in each case to the extent arising from the gross negligence or willful misconduct of Inverness or the breach by Inverness of any representation, warranty or covenant under this Agreement.

6.2 By Inverness. Inverness shall indemnify and hold harmless OraSure from all losses, liabilities, damages and expenses (including reasonable attorneys’ fees and costs) resulting from any claims, demands, actions or other proceedings by any third party to the extent resulting from (a) any breach by Inverness of any representation, warranty or covenant under this

13

Agreement, or (b) the gross negligence or willful misconduct of Inverness in the performance of its obligations or exercise of its rights under this Agreement, except in each case to the extent arising from the gross negligence or willful misconduct of OraSure or the breach by OraSure of any representation, warranty or covenant under this Agreement.

6.3 Procedure. A party (the “Indemnitee”) that intends to claim indemnification under this Article 6 shall promptly notify the other party (the “Indemnitor”), of any claim, demand, action or other proceeding for which the Indemnitee intends to claim such indemnification. The Indemnitor shall have the right to participate in, and to the extent the Indemnitor so desires to assume, the defense thereof with counsel selected by the Indemnitor; provided, however, that the Indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitor, if representation of the Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential differing interests between the Indemnitee and any other party represented by such counsel in such proceeding. The indemnity obligations under this Article 6 shall not apply to amounts paid in settlement of any claim, demand, action or other proceeding if such settlement is effected without the prior express written consent of the Indemnitor, which consent shall not be unreasonably withheld or delayed. The failure to deliver notice to the Indemnitor within a reasonable time after notice of any such claim or demand, or the commencement of any such action or other proceeding, if prejudicial to its ability to defend such claim, demand, action or other proceeding, shall relieve such Indemnitor of any liability to the Indemnitee under this Article 6 with respect thereto, but the omission so to deliver notice to the Indemnitor shall not relieve it of any liability that it may have to the Indemnitee otherwise than under this Article 6. The Indemnitor may not settle or otherwise consent to an adverse judgment in any such claim, demand, action or other proceeding, that diminishes the rights or interests of the Indemnitee without the prior express written consent of the Indemnitee, which consent shall not be unreasonably withheld or delayed. The Indemnitee, its employees and agents, shall reasonably cooperate with the Indemnitor and its legal representatives in the investigation and defense of any claim, demand, action or other proceeding covered by this Article 6.

ARTICLE 7

EXHIBIT C

ORAQUICK^® HCV PRODUCTS

The OraQuick^® Rapid HCV Antibody Test is a lateral flow immunoassay device contained within a device housing that utilizes an indirect immunoassay method in a lateral flow device to detect antibodies to HCV in a blood sample (including without limitation blood via fingerstick or venipuncture, plasma, serum) or in an oral fluid sample.

Such oral fluid samples are collected directly on a swab protruding from the device and placed into a developer solution. Such blood samples are collected via a collection device (including without limitation a specimen collection loop) and mixed in a container with a developer solution.

In the device, antigens derived from HCV are placed on a test area (including without limitation a test line) on a porous membrane (including without limitation a nitrocellulose strip), and antibodies reactive with these antigens are visualized by a protein A, particle labeled conjugate.

The device comprises a series of components from upstream to downstream—the blocker pad, the conjugate pad, the porous membrane, and finally the absorbent pad. The performance of the assay occurs as a mixture of the specimen and developer solution moves along the test device, carrying the specimen and the substances on the test device from the blocker pad to the absorbent pad.

As the mixture of the specimen and developer solution flows along the device, antibodies, if present in the specimen, are bound to the protein A, particle labeled conjugate. Labeled complexes then migrate along the porous membrane until they reach the test area. At the test area, labeled complexes containing HCV antibodies bind to the HCV antigens at the test area.

Reactive results generate a visible signal at the test area of the device that is viewed by the human eye.

The OraQuick^® Rapid HCV Antibody Test will be described with more particularity in a package insert approved from time to time by the U.S. Food and Drug Administration, as such package insert may be updated from time to time after approval by the U.S. Food and Drug Administration.

ORAQUICK^® HIV PRODUCTS

The OraQuick^® Rapid HIV Antibody Test is a lateral flow immunoassay device contained within a device housing that utilizes an indirect immunoassay method in a lateral flow device to detect antibodies to HIV in a blood sample (including without limitation blood via fingerstick or venipuncture, plasma, serum) or in an oral fluid sample.

Such oral fluid samples are collected directly on a swab protruding from the device and placed into a developer solution. Such blood samples are collected via a collection device (including without limitation a specimen collection loop) and mixed in a container with a developer solution.

In the device, antigens derived from HIV are placed on a test area (including without limitation a test line) on a porous membrane (including without limitation a nitrocellulose strip), and antibodies reactive with these antigens are visualized by a protein A, particle labeled conjugate.
