In addition, the report 9 shall clearly show the Net Revenues and Net Sales for the months of the [* * *] for which payment is being made on a country by country basis.

If so required by applicable law any payment made pursuant to this Agreement shall be made by Emisphere after deduction of the appropriate withholding tax, in which 10 event the parties shall co-operate to obtain the appropriate tax clearance as soon as is practicable. On receipt of such clearance, Emisphere shall forthwith procure that the amount so withheld is paid to Elan. 5.11 Method of calculation of royalties and fees: The parties acknowledge and agree that the methods for calculating the royalties and fees hereunder are for the purposes of the convenience of the parties, are freely chosen and not coerced. 6.

Any such inspection of Emisphere's records shall be at the expense of Elan, except that if any such inspection reveals a deficiency in the amount of the running royalty actually paid to Elan hereunder in any calendar year of [* * *] or more of the amount of any running royalty actually due to Elan hereunder, then the expense of such inspection shall be borne solely by Emisphere. Any amount of deficiency shall be paid promptly to Elan. If such inspection reveals a surplus in the amount of running royalty actually paid to Elan by Emisphere, Elan shall promptly reimburse Emisphere the surplus. 6.2 In the event of any unresolved dispute regarding any alleged deficiency or overpayment of royalty payments hereunder, the matter will be referred to [* * *] for a resolution of such dispute. Any decision by the [* * *] shall be [* * *] on the parties. 7. PATENTS 7.1 Elan, at its expense, shall [* * *] to maintain in force any [* * *] issued letters patent within the Elan Patent that relate to the Field.

At Elan's request and expense, Emisphere shall co-operate with such action. Should Elan decide not to pursue such infringers insofar as such infringements relate solely to the Field, within a reasonable period but in any event within 20 days after receiving written notice of such alleged infringement, Emisphere may in its discretion initiate such proceedings in its own name at its expense and for its own benefit and at Emisphere's request and expense, Elan shall cooperate with such action. 8. CONFIDENTIAL INFORMATION 8.1 The parties acknowledge that it may be necessary, from time to time, solely for the purposes of each party performing this Agreement, to disclose to each other confidential and proprietary information ("Confidential Information"). 8.2 Any Confidential Information revealed by a party to another party shall be used by the receiving party exclusively for the purposes of fulfilling the receiving party's obligations under this Agreement and for no other purpose. 8.3 Each party agrees to disclose Confidential Information of another party only to those employees, representatives and agents requiring knowledge thereof in connection with their duties directly related to the fulfilling of the party's obligations under this Agreement. Each party further agrees to inform all such employees, representatives and agents of the terms and provisions of this Agreement and their duties hereunder and to obtain their consent hereto as a condition of receiving Confidential Information. Each party agrees that it will exercise the same degree of care, but in no event less than a reasonable degree, and protection to preserve the proprietary and confidential nature of the Confidential Information disclosed by a party, as the receiving party would exercise to preserve its own proprietary and confidential information. Each party agrees that it will, upon request of a party, return all documents and any copies thereof containing Confidential Information belonging to or disclosed by such party. 8.4 Any breach of this Clause 8 by any of the persons informed by one of the parties is considered a breach by the party itself. 12 Confidential Information shall not be deemed to include: (i) information that is in the public domain; (ii) is in the possession of the recipient at the time of disclosure; (iii) information which is independently developed by a party; (iv) information that becomes available to a party on a non- confidential basis from a third party who is under no confidentiality obligations to the party disclosing Confidential Information 8.5 If any party or any of its representatives or Affiliates becomes legally compelled (by deposition, interrogatory, request for documents, subpoena, civil investigative demand or similar process) to disclose any of the other party's Confidential Information, such party shall provide the other party with prompt prior written notice and may disclose that portion of the other party's Confidential Information that is legally required and shall [* * *] obtain (and shall cooperate with the other party's efforts to obtain) assurance that confidential treatment will be accorded the other party's Confidential Information. If either party is required by law to make any public disclosure, including any public filings required to be made under the rules or regulations of the U.S. Securities and Exchange Commission, the Nasdaq Stock Market or other national securities exchange, otherwise prohibited by this Agreement, such party shall provide the other party with prompt prior written notice and may disclose that portion of the other party's Confidential Information that is legally required and shall [* * *] obtain (and shall cooperate with the other party's efforts to obtain) assurance that confidential treatment will be accorded the other party's Confidential Information. 8.6 The parties agree that the obligations of this Clause 8 are necessary and reasonable in order to protect the parties' respective businesses, and each party expressly agrees that monetary damages would be inadequate to compensate a party for any breach by the other party of its covenants and agreements set forth herein. Accordingly, the parties agree and acknowledge that any such violation or threatened violation will cause irreparable injury to a party and that, in addition to any other remedies that may be available, in law and equity or otherwise, any party shall be entitled to obtain injunctive relief against the threatened breach of the provisions of this Clause 8, or a continuation of any such breach by the other party, specific performance and other equitable relief to redress 13 such breach together with its damages and reasonable counsel fees and expenses to enforce its rights hereunder, without the necessity of proving actual or express damages. 8.7 Subject only to the specific exceptions set forth in this Clause 8 and Clause 8.4 of the Termination Agreement, none of the parties shall disclose the existence of this Agreement or the other agreements entered into by the parties on the Effective Date, the subject matter hereof nor originate any publicity, new release or other public announcement, written or oral without the written consent of the other parties. 9.

If the breaching party has proposed a course of action to rectify the breach and is acting in good faith to rectify same but has not cured the breach by the [* * *] day, the said period shall be extended by such period as is reasonably necessary to enable the breach to be cured. 9.4 If at any time during the term of this Agreement, an "Event of Bankruptcy" (as defined below) relating to Emisphere occurs, Elan shall 14 have, in addition to all other legal and equitable rights and remedies available hereunder, the option to terminate this Agreement upon [* * *] written notice, given within [* * *] days following the date that Elan becomes aware of the Event of Bankruptcy.
