The Sellers further agree to obtain prior approval from the Purchaser of any promotional material for Generic Product that references the Peridex Oral Rinse product by name. The parties hereto specifically acknowledge and agree that the remedy at law for any breach of the foregoing will be inadequate and that the Purchaser, in addition to any other relief available to it, shall be entitled to temporary and permanent injunctive relief without the necessity of proving actual damage. In the event that the provisions of this Section 5.08 should ever be deemed to exceed the limitation provided by applicable law, then the parties hereto agree that such provisions shall be reformed to set forth the maximum limitations permitted.

The Purchaser and its Affiliates, officers, directors, employees, agents, successors and assigns (each, a “Purchaser Indemnified Party”) shall be indemnified and held harmless by the Sellers, jointly and severally, for and against all losses, damages, claims, costs and expenses, interest, awards, judgments and penalties (including reasonable attorneys’ and consultants’ fees and expenses) actually suffered or incurred by them (hereinafter, a “Loss”), arising out of or resulting from: (a) the breach of any representation or warranty made by the Sellers contained in this Agreement; (b) the breach of any covenant or agreement by the Sellers contained in this Agreement; (c) the Excluded Assets; (d) the Excluded Liabilities; and (e) the conduct of the Business by Sellers prior to the date of the Closing.

SECTION 7.03 Indemnification by the Purchaser. The Sellers and their Affiliates, officers, directors, employees, agents, successors and assigns (each, a “Seller Indemnified Party”) shall be indemnified and held harmless by the Purchaser for and against any and all Losses, arising out of or resulting from: (a) the breach of any representation or warranty made by the Purchaser contained in this Agreement; (b) the breach of any covenant or agreement by the Purchaser contained in this Agreement; (c) the Assumed Liabilities; (d) the Purchased Assets; (e) the conduct of the Business by the Purchaser on and following the date of Closing; or (f) any claim or cause of action by any person arising before or after the Closing against any Seller Indemnified Party with respect to the Business or the Purchased Assets, except for claims or causes of action with respect to which the Seller is obligated to indemnify the Purchaser Indemnified Parties pursuant to Section 7.02.

SECTION 7.04 Limits on Indemnification. (a) No claim may be asserted nor may any Action be commenced against either party hereto for breach of any representation, warranty, covenant or agreement contained herein, unless written notice of such claim or action is received by such party describing in reasonable detail the facts and circumstances with respect to the subject matter of such claim or Action on or prior to the date on which the representation, warranty, covenant or agreement on which such claim or Action is based ceases to survive as set forth in Section 7.01, irrespective of whether the subject matter of such claim or action shall have occurred before or after such date.

(b) Notwithstanding anything to the contrary contained in this Agreement: (i) an Indemnifying Party shall not be liable for any claim for indemnification pursuant to Section 7.02 or Section 7.03, unless and until the aggregate amount of indemnifiable Losses which may be recovered from the Indemnifying Party equals or exceeds ninety five thousand dollars ($95,000), after which the Indemnifying Party may be liable for Losses from the

first dollar (the “Threshold”); (ii) no Losses may be claimed under Section 7.02 or Section 7.03 by any Purchaser Indemnified Party or shall be reimbursable by or shall be included in calculating the aggregate Losses set forth in clause (i) above other than Losses in excess of ten thousand dollars ($10,000) resulting from any single claim or aggregated claims arising out of the same facts, events or circumstances (the “Mini-Threshold”); (iii) the maximum amount of indemnifiable Losses which may be recovered from an Indemnifying Party arising out of or resulting from the causes shall be an amount equal to the Purchase Price (the “Cap”); (iv) neither party hereto shall have any liability under any provision of this Agreement or the ▇▇▇▇ of Sale, Assignment and Assumption Agreement for any punitive, incidental, consequential, special or indirect damages, including loss of future revenue or income, or loss of business reputation or opportunity relating to the breach or alleged breach of this Agreement or the ▇▇▇▇ of Sale, Assignment and Assumption Agreement, and (v) claims relating to (x) fraud or intentional misrepresentations, (y) breaches of Fundamental Reps or the covenants set forth in Section 5.01, 5.02, 5.06, 5.07 and 5.08, or (z) relating to unpaid transaction expenses of the Sellers or Excluded liabilities (the “Excluded Claims”), will not be subject to the Threshold, the Mini-Threshold or the Cap. Purchaser’s ability to seek indemnity will not be affected by any investigation, inquiry, knowledge, or examination by Purchaser. Materiality and Material Adverse Effect (but not knowledge) qualifiers will be disregarded for purposes of determining that there was a breach of this Agreement and the amount of Losses subject to indemnification.

(c) For all purposes of this Article VII, “Losses” shall be net of any insurance or other recoveries actually received by the Indemnified Party or its Affiliates in connection with the facts giving rise to the right of indemnification.

SECTION 7.05 Notice of Loss; Third Party Claims. (a) An Indemnified Party shall give the Indemnifying Party notice of any matter which an Indemnified Party has determined has given or could give rise to a right of indemnification under this Agreement, within 60 days of such determination, stating the amount of the Loss, if known, and method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises.

(b) If an Indemnified Party shall receive notice of any Action, audit, claim, demand or assessment (each, a “Third Party Claim”) against it which may give rise to a claim for Loss under this Article VII, within 30 days of the receipt of such notice, the Indemnified Party shall give the Indemnifying Party notice of such Third Party Claim; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations under this Article VII except to the extent that the Indemnified Party is materially prejudiced by such failure and shall not relieve the Indemnifying Party from any other Liability that it may have to any Indemnified Party other than under this Article VII. The Indemnifying Party shall be entitled to assume and control the defense of such Third Party Claim at its expense and through counsel of its choice if it gives notice of its intention to do so to the Indemnified Party within 15 days of the receipt of such notice from the Indemnified Party. If the Indemnifying Party elects to undertake any such defense against a Third Party Claim the Indemnified Party may participate in such defense at its own expense. The Indemnified Party shall cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party, at the Indemnifying Party’s expense, all witnesses, pertinent records, materials and information in the Indemnified Party’s possession or under the Indemnified Party’s

control relating thereto as is reasonably required by the Indemnifying Party. If the Indemnifying Party elects to direct the defense of any such claim or proceeding, the Indemnified Party shall not pay, or permit to be paid, any part of such Third Party Claim unless the Indemnifying Party consents in writing to such payment or unless the Indemnifying Party withdraws from the defense of such Third Party Claim liability or unless a final judgment from which no appeal may be taken by or on behalf of the Indemnifying Party is entered against the Indemnified Party for such Third Party Claim. If the Indemnified Party assumes the defense of any such claims or proceeding pursuant to this Section 7.05 and proposes to settle such claims or proceeding prior to a final judgment thereon or to forgo any appeal with respect thereto, then the Indemnified Party shall give the Indemnifying Party prompt written notice thereof and the Indemnifying Party shall have the right to participate in the settlement or assume or reassume the defense of such claims or proceeding.

SECTION 7.06 Tax Treatment. To the extent permitted by Law, the parties hereto agree to treat all payments made under this Article VII, under any other indemnity provision contained in this Agreement, and for any misrepresentations or breach of warranties or covenants, as adjustments to the Purchase Price for all Tax purposes.

SECTION 7.07 Remedies. The Purchaser and the Sellers acknowledge and agree that (a) following the Closing, the indemnification provisions of Section 7.02 and Section 7.03 shall be the sole and exclusive remedies of the Purchaser and the Sellers for any breach by the other party of the representations and warranties in this Agreement and for any failure by the other party to perform and comply with any covenants and agreements in this Agreement, and (b) anything herein to the contrary notwithstanding, no breach of any representation, warranty, covenant or agreement contained herein shall give rise to any right on the part of the Purchaser or the Sellers, after the consummation of the purchase and sale of the Purchased Assets contemplated by this Agreement, to rescind this Agreement or any of the transactions contemplated hereby. Each party hereto shall take all reasonable steps to mitigate its Losses upon and after becoming aware of any event which could reasonably be expected to give rise to any Losses.

Neither party to this Agreement shall make, or cause to be made, any press release or public announcement in respect of this Agreement or the transactions contemplated by this Agreement or otherwise communicate with any news media without the prior written consent of the other party unless otherwise required by Law or applicable stock exchange regulation, and the parties to this Agreement shall cooperate as to the timing and contents of any such press release, public announcement or communication.

SECTION 9.04 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect for so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to either party hereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated by this Agreement are consummated as originally contemplated to the greatest extent possible.

SECTION 9.05 Entire Agreement. This Agreement and the ▇▇▇▇ of Sale, Assignment and Assumption Agreement constitute the entire agreement of the parties hereto with respect to the subject matter hereof and thereof and supersede all prior agreements and undertakings, both written and oral, between the Sellers and the Purchaser with respect to the subject matter hereof and thereof.

SECTION 9.06 Assignment. This Agreement may not be assigned by operation of law or otherwise without the express written consent of the Sellers and the Purchaser (which consent may be granted or withheld in the sole discretion of the Sellers or the Purchaser), as the case may be.

Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the party to be

bound thereby. Any waiver of any term or condition shall not be construed as a waiver of any subsequent breach or a subsequent waiver of the same term or condition, or a waiver of any other term or condition of this Agreement. The failure of either party hereto to assert any of its rights hereunder shall not constitute a waiver of any of such rights.

SECTION 9.09 No Third Party Beneficiaries. This Agreement shall be binding upon and inure solely to the benefit of the parties hereto and their respective successors and permitted assigns and nothing herein, express or implied (including the provisions of Article VII relating to indemnified parties), is intended to or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever, including any rights of employment for any specified period, under or by reason of this Agreement.

SECTION 9.10 Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware. All Actions arising out of or relating to this Agreement shall be heard and determined exclusively in any Delaware federal court sitting in Newcastle County; provided, however, that if such federal court does not have jurisdiction over such Action, such Action shall be heard and determined exclusively in any state court sitting in the city of Wilmington, Delaware. Consistent with the preceding sentence, the parties hereto hereby (a) submit to the exclusive jurisdiction of any federal or state court sitting in the city of Wilmington, Delaware for the purpose of any Action arising out of or relating to this Agreement brought by either party hereto and (b) irrevocably waive, and agree not to assert by way of motion, defense, or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper, or that this Agreement or the transactions contemplated by this Agreement may not be enforced in or by any of the above named courts.

SECTION 9.11 Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH OF THE PARTIES HERETO HEREBY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.11.
