The Inventor will own any Improvements developed by him, provided that the work to develop such Improvements was not performed pursuant to a contract requiring such work between the Inventor and AlgoRx, and provided that no resources or Confidential Information of AlgoRx were used for such work. Such Improvements as in effect as of the Effective Date are included within the Licensed Technology. The Inventor acknowledges his obligations under the Main License Agreement as to Improvements thereunder. 5.2 Third Party Rights In Improvements. The Inventor represents that he is not a party to any agreement existing as of the Effective Date pursuant to which third parties are supporting, funding, or contributing to any research designed to lead to any Improvements and/or granting rights in any Improvements. 5.3 Ownership Of Improvements Developed By AlgoRx. Any technology or Improvements conceived or developed by AlgoRx whether on its own or by third parties, pursuant to work carried out under contract for AlgoRx, or otherwise involving the use of resources belonging to AlgoRx, whether facilities, materials or AlgoRx Confidential Information, will be the property of AlgoRx. 5.4 Publications. The Inventor acknowledges that publication or oral disclosure of any work carried out in connection with the Licensed Technology, including Improvements existing at the Effective Date, or of the results of such work, prior to the date of filing for patent, copyright or other applicable statutory protection, could result in the loss of commercial value of any such work or results. The Inventor will therefore provide AlgoRx with sufficient disclosure in writing regarding any matter related to work and work results or other intellectual property related to the Licensed Technology, including Improvements, existing at the Effective Date, at least ninety (90) days prior to publication of any kind with respect thereto by anyone other than AlgoRx, to allow AlgoRx to evaluate such proposed disclosure as it may affect AlgoRx's interests. The Inventor will consult with AlgoRx prior to any such disclosure or publication and will in good faith consider modifications to such proposed publication if such disclosure regarding work, work results or intellectual property relating to the Licensed Technology would, in AlgoRx's good faith view, as communicated to the Inventor in a writing signed by the President or Chief Executive Officer of AlgoRx, would materially adversely affect the business of AlgoRx. The provisions of Section 5.5 of the Main License Agreement will apply to any publication by the Inventor related to Injectable Products or Services. 5.5 Infringement Of Licensed Patents. This Section 5.5 will apply only if AlgoRx obtains an exclusive license or assignment to the Licensed Technology pursuant to Section 2.3, provided that nothing in this Agreement will be deemed or construed to prevent or limit any rights of AlgoRx to take any lawful action, or to refrain from taking any action, as a licensee hereunder. 5.5.1 Notice. Each party will promptly report to the other party promptly in writing as to any known or suspected infringement of any of the patent rights within the Licensed Patents, and will provide the other party with all information available to such notifying party with respect to such infringement or suspected infringement. -7- AlgoRx Pharmaceuticals, Inc. - Capsaicin License -- Marco Pappagallo 5.5.2 Action By AlgoRx. If AlgoRx believes that any patent rights within the Licensed Patents have been infringed by any third party, AlgoRx, subject to applicable law, will have the right at its discretion to negotiate to obtain an agreement to end such infringement or use without authorization. If such negotiation is unsuccessful, AlgoRx will have the right, in its commercially reasonable judgment and subject to applicable law, to institute an infringement action or other appropriate legal action against such third party, and, in its commercially reasonable judgment, to settle any such action or dispute, provided that AlgoRx will not compromise or settle any such action without the prior written consent of the Inventor, which consent the Inventor will not unreasonably or untimely withhold. AlgoRx will have the sole and exclusive right to select counsel and will pay all expenses of any such action, including without limitation attorneys' fees and court costs, provided that (1) if there is a determination, by the court or authorized body resolving such action, of gross negligence, intentional misrepresentation or fraud by the Inventor, then the Inventor will, upon the written request of AlgoRx to the Inventor and subject to clause (2) immediately following, promptly pay, or promptly reimburse AlgoRx for, the expenses of such action as such reimbursement or payment amount will be set forth in AlgoRx's written request therefor, provided that if the Inventor has been determined to have committed fraud there will be no limit as to liability of the Inventor to AlgoRx. Notwithstanding anything in the foregoing to the contrary, AlgoRx recognizes that Inventor did not direct (and was not involved in) the prosecution of the Licensed Patents. Any damages, royalties, settlement fees or other consideration paid by the third party infringer as a result of legal action or settlement negotiations in connection with such infringement will be paid to and will be the property of AlgoRx. The amount of such damages, royalties, settlement fees, or other consideration actually received by AlgoRx, net of the expenses incurred by AlgoRx in such legal action, will be treated as Net Sales pursuant to Article 2 and a royalty in accordance with Sections 2.3 and 3,2 on such net amount will be payable by AlgoRx to the Inventor in respect of such amount, as part of the royalty provided in Article 2, provided that the value of any non-cash consideration so received by AlgoRx will be determined in good faith by the Board of Directors of AlgoRx and all royalty amounts thereon will, as calculated upon such determined fair market value, be paid to the Inventor in cash and not in kind. If deemed necessary by AlgoRx, the Inventor, subject to applicable law, will bring suit against third party infringers or join as a party to the action, at AlgoRx's option and expense. To the extent that AlgoRx has paid for the expenses of such action, any damages, royalties, settlement fees or other consideration paid by the third party infringer as a result of such legal action in connection with such infringement will be held by the Inventor as agent for AlgoRx and will be remitted by them to AlgoRx promptly after their receipt thereof. 5.5.3 Action By The Inventor. If AlgoRx declines to act pursuant to Section 5.5.2. AlgoRx will, promptly after such decision not to act, give written notice to the Inventor of such decision. If the Inventor believes, after delivery of such notice by AlgoRx, that any patent rights within the Licensed Patents have been infringed by any third party, the Inventor may at his expense take any action the sees fit with respect to such infringement, including initiating legal proceedings. If the Inventor commences any such action, the Inventor will promptly notify AlgoRx, in writing in commercially reasonable detail, of such commencement. In exercising his rights pursuant to this Section 5.5.3, the Inventor will have the sole and exclusive right to select counsel and will, except as provided below, pay all expenses of the action, including without limitation attorneys' fees and costs, and will have the right, in his commercially reasonable judgment, to settle any such action or dispute, provided that the Inventor will not compromise or settle any such action without the prior written consent of AlgoRx, which consent will not be unreasonably or untimely withheld. AlgoRx, in its sole discretion, and subject to the limitations stated in the last sentence of this Section 5.5.3, may elect in writing to the Inventor, within sixty -8- AlgoRx Pharmaceuticals, Inc. - Capsaicin License -- Marco Pappagallo (60) days after the commencement of such litigation, to contribute to the costs incurred by the Inventor in connection with such litigation. Any damage, royalties, settlement fees or other consideration received by the Inventor as a result of such litigation will be shared by the Inventor and AlgoRx pro rata based on their respective sharing of the costs of such litigation. If deemed necessary by the Inventor, or by AlgoRx, by written notice to the other, AlgoRx will join as a party to the action but will be under no obligation to participate except to the extent that such participation is required as a result of being a named party to the action. At the written request of the Inventor if he is participating in such action, AlgoRx will offer reasonable assistance in connection therewith at no charge to the Inventor provided that for purposes of this Section 5.5.3, all out-of-pocket expenses incurred by AlgoRx in rendering such assistance will be treated as amounts contributed by AlgoRx to the costs of such litigation. AlgoRx will have the right to participate in and be represented in any such action by its own counsel at its own expense. 5.6 Infringement Actions By Third Parties. 5.6.1 Notice; Defense By AlgoRx. In the event of the institution of any action by a third party against AlgoRx or the Inventor for patent infringement involving the manufacture, use, distribution, marketing or sale of any Licensed Product or performance of any Licensed Service, the defendant party hereto will promptly notify the other party hereto in writing of such action if such action includes claims with respect to the Licensed Patents. AlgoRx will have the right to defend such action at its own expense, and the Inventor will assist and cooperate with AlgoRx, at AlgoRx's expense, to the extent necessary in the defense of such action. During the pendency of such action, AlgoRx will pay any royalties for Licensed Products or Licensed Services for which such infringement is claimed, with respect to the country or countries or other political jurisdiction(s) in which such infringement is claimed, into an escrow account to be implemented by AlgoRx at such bank as the Board of Directors of AlgoRx, acting in good faith, determines, and with the fees and cost of implementing and operating such escrow account to be paid by AlgoRx, provided that AlgoRx will during such pendency continue to pay royalties, as otherwise provided in this Agreement, with respect to all other Licensed Products or Licensed Services, and other countries or other political jurisdictions, with respect to which, in each case, no allegation of infringement has been made,. 5.6.2 AlgoRx As Prevailing Party. If AlgoRx finally prevails because it is held not to be infringing any patents belonging to such third party or because such third party's patent is held invalid, AlgoRx will remit to the Inventor the royalties kept in escrow pursuant to Section 5.6.1, to the extent the Licensed Products or Licensed Services made the subject of the action are determined to have been, and to be, Products or Services Covered by a Valid Claim, and will continue to pay the royalties as set forth in Article 2, provided that AlgoRx will be entitled to a credit against payments due under this Agreement of an amount equal to one-half (1/2) of the commercially reasonable costs actually incurred by AlgoRx in such action, and further provided that in no event will such credit be more than fifty percent (50%) of such payments due hereunder for Licensed Products or Licensed Services in such country or other political jurisdiction which is the subject of such action. Any such credit not deducted for a calendar quarter as a result of the immediately preceding sentence may be carried forward and deducted by AlgoRx in subsequent calendar quarters. 5.6.3 AlgoRx Not As Prevailing Party. If AlgoRx finally is not the prevailing party in such action, whether by judgment, award, decree or settlement, and is required to pay a royalty to such third party, AlgoRx will keep the royalties kept in escrow pursuant to Section 5.6.1 as a reimbursement of such royalties payable to a third party and, if the escrowed -9- AlgoRx Pharmaceuticals, Inc. - Capsaicin License -- Marco Pappagallo amount is insufficient to reimburse AlgoRx for such royalties payable to a third party, will continue to pay to the Inventor the royalties for such Licensed Products or Licensed Services in such country or other political jurisdiction which is the subject of such action, if such Licensed Products or Licensed Services are, therein, Products or Services Covered by a Valid Claim, but AlgoRx will be entitled to a credit against any payments due under this Agreement of an amount equal to the royalty paid to such third party, provided that in no event will such credit be more than fifty percent (50%) of the payment due hereunder for Licensed Products or Licensed Services in such country or other political jurisdiction which is the subject of such action. In addition, if AlgoRx incurs litigation expenses or is required to pay damages to such third party, AlgoRx will be entitled to a credit against payments due under this Agreement of the reasonable costs actually incurred in such action plus the damages payable to the third party, until such costs and damages are recovered in full by AlgoRx. The credit for expenses and damages (taken with the foregoing credit for royalties to third parties) will, together, not be more than fifty percent (50%) of the payment due hereunder by AlgoRx for Licensed Products or Licensed Services, in such country or countries and such other political jurisdiction(s), which are the subject of such action for the relevant period, but such credit for expenses and damages will be extended for successive periods until the entire amount of such expenses and damages incurred by AlgoRx has been recovered; no credit will be afforded hereunder to AlgoRx if AlgoRx is found by a court or other body of competent jurisdiction to have intentionally infringed a third party's patent, or to have been unintentional but grossly negligent in infringing a third party's patent. 5.6.4 Defense By The Inventor. If AlgoRx declines to defend such action by a third party against the Inventor for patent infringement involving the manufacture, use, distribution, marketing or sale of any Licensed Product or performance of any Licensed Services, the Inventor may defend such action at his own expense and will be entitled to require assistance from AlgoRx at the Inventor's expense. 5.6.5 Consents To Settlement And Compromise. If AlgoRx defends an action pursuant to Section 5.6.1, AlgoRx will not compromise or settle any such action without the prior written consent of the Inventor, which will not be unreasonably or untimely withheld. If the Inventor defends an action pursuant to Section 5.6.4, the Inventor will not compromise or settle any such action without the prior written consent of AlgoRx, which will not be unreasonably or untimely withheld. 5.7 Patent Prosecution And Maintenance. AlgoRx may at its election and subject to applicable law take over the prosecution and maintenance of the Licensed Patents, including filing new applications in foreign countries corresponding to any of the Licensed Patents, and any proceedings concerning assertion of inventorship or ownership by the Inventor with respect to any of the Licensed Patents or corresponding applications in foreign countries (each an "Ownership Proceeding"), or filing in the United States and foreign countries for patents relating to any existing Improvements made by the Inventor. The Inventor, however, makes no representation or warranty as to the achievability of any such action. If AlgoRx takes over such prosecution and maintenance, AlgoRx will decide whether to file an application for patenting, or otherwise pursue prosecution of, elements of the Licensed Technology in a particular jurisdiction, and will decide whether it will fund any Ownership Proceedings. If AlgoRx takes over such prosecution and maintenance, and thereafter declines to pursue patent protection for an element of the Licensed Technology in a particular jurisdiction, or decides not to fund an Ownership Proceeding, (a) AlgoRx will promptly after such decision not to act, give written notice to the Inventor of such decision, and (b) after delivery of such notice, the Inventor may at his expense take any action he sees fit with respect to such filing or other prosecution or with -10- AlgoRx Pharmaceuticals, Inc. - Capsaicin License -- Marco Pappagallo respect to such Ownership Proceeding(s), provided that the Inventor will undertake no action with respect to any Ownership Proceeding unless such action is approved in writing by AlgoRx, which approval AlgoRx will not unreasonably or untimely withhold. Any applications for patents (or patents resulting from such applications) so prosecuted by the Inventor, or obtained by the Inventor as a result of an Ownership Proceeding, will be included in the Licensed Technology, and the Inventor will comply with the obligations provided in this Agreement with respect to such applications and patents. If the Inventor chooses to seek such protection, AlgoRx hereby grants the Inventor the right, subject to the provisions of Article 8, to use information relating to the Licensed Technology solely for the purposes of filing and prosecuting such application.

ARTICLE 8 CONFIDENTIALITY 8.1 Confidential Information. It is contemplated that in the course of the performance of this Agreement each party will, from time to time, disclose proprietary and confidential information to the other. For purposes of this Agreement, "Confidential Information" means all confidential and proprietary information of one party hereto disclosed by such party to the other party during the term of this Agreement, including information contained in all tangible materials, such as but not limited to samples of chemical substances and drugs, instruments, and other materials remitted to a party, and which the disclosing party identifies as confidential to the receiving party in writing ("writing" to include, for purposes of this Agreement, electronic communication such as email, and to include without limitation a stamping or legend denoting the confidential and/or proprietary nature of such information placed on the first page and/or on subsequent pages of printed or electronic forms of such information) either before, or at the time of, such disclosure, if such disclosure is initially in written form, or, if initially orally disclosed, then as so identified in writing by the disclosing party to the receiving party within thirty (30) days after such initial oral disclosure. 8.2 Confidentiality Exceptions. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the parties, the receiving party will keep confidential, and will take such reasonable measures to maintain such Confidential Information of the disclosing party as confidential as it takes to protect its own proprietary Confidential Information, and will not publish or otherwise disclose and will not use for any purpose any -12- AlgoRx Pharmaceuticals, Inc. - Capsaicin License -- Marco Pappagallo Confidential Information furnished to it by the other party pursuant to this Agreement, except to the extent that it can be established by the receiving party by competent proof that such Confidential Information: (a) was already known to the receiving party, other than under an obligation of confidentiality, at the time of disclosure by the other party; (b) was generally available to the public or otherwise part of the public domain, other than through any act or omission of the receiving party in breach of this Agreement, at the time of its disclosure to the receiving party; (c) after its disclosure to the receiving party became generally available to the public or otherwise part of the public domain other than through any act or omission of the receiving party in breach of this Agreement; (d) was disclosed to the receiving party by a third party who had no obligation to the disclosing party not to disclose such Confidential Information to others; or (e) was independently developed by the receiving party by persons who did not have access to the Confidential Information, and other than through any act or omission of the receiving party in breach of this Agreement. 8.3 Permitted Uses. Each party may disclose the other's Confidential Information to the extent such disclosure is reasonably necessary in filing or prosecuting patent applications, prosecuting or defending litigation or complying with applicable governmental regulations, provided that if a party is required to make any such disclosure of the other party's Confidential Information it will give reasonable advance written notice to the other party of such disclosure requirement, describing such requirement in commercially reasonable detail, and, except to the extent commercially inappropriate in the case of pending patent applications, will use its best efforts to secure confidential treatment of such Confidential Information so required to be disclosed. AlgoRx may disclose any Confidential Information of the Inventor to any sublicensee of AlgoRx so long as such disclosure is limited to Confidential Information the sublicensee needs to know, in the commercially reasonable and good faith judgment of AlgoRx, in order for such sublicensee to fulfill its obligations under its sublicense from AlgoRx and provided that such sublicensee is required in writing by AlgoRx to preserve the confidentiality of such Confidential Information under obligations at least as stringent as those imposed upon AlgoRx under this Agreement.

At the end of such one hundred and eighty (180) day grace period, all remaining Licensed Products not disposed of by AlgoRx will either be destroyed by AlgoRx, or purchased by the Inventor, at the Inventor's election as communicated in writing to AlgoRx at least forty-five (45) days prior to the end of such grace period. AlgoRx will have a further thirty (30) days after the end of such grace period to prepare the final report and pay the royalties applicable to Net Sales during such one hundred and eighty (180) day grace period; (c) AlgoRx will remit to the Inventor all documentation and materials relating to prosecution and maintenance of Licensed Patents, as well as all Confidential Information relating to the Licensed Technology, in each case that is in possession of AlgoRx. -14- AlgoRx Pharmaceuticals, Inc. - Capsaicin License -- Marco Pappagallo 9.5 Surviving Obligations.
