WITNESSETH

     WHEREAS, DUSA is the owner, by virtue of its acquisition of Sirius Laboratories, Inc., of U.S. Patent No. 6,979,468 entitled “Oral Composition and Method for the Treatment of Inflammatory Cutaneous Disorders” (the “‘468 Patent”), under which DUSA has manufactured, marketed, distributed, and sold its Nicomide^® product; and

     WHEREAS, River’s Edge has manufactured, marketed, distributed, and sold a product labeled as NIC 750 that competes with DUSA’s Nicomide^® product; and

     WHEREAS, on April 20, 2006, DUSA filed an action in the United States District Court, District of New Jersey against River’s Edge entitled DUSA Pharmaceuticals, Inc., et al. v. River’s Edge Pharmaceuticals, Inc., and assigned Civil Action No. 06-1843 (SRC) (the “New Jersey Litigation”), in which DUSA has alleged, among other things, that River’s Edge’s NIC 750 product infringes on the ‘468 Patent; and

     WHEREAS, on March 28, 2006, River’s Edge filed a separate action in the United States District Court, Northern District of Georgia against DUSA entitled River’s Edge Pharmaceuticals, Inc. v. DUSA Pharmaceuticals, Inc., et al., and assigned Civil Action No. 06-CV- 00045 (WCO) (the “Georgia Litigation”), which action was later dismissed in favor of the New Jersey Litigation; and

     WHEREAS, the New Jersey Litigation was referred by the Court to mediation before the Honorable Nicholas H. Politan, U.S.D.J. (retired) on August 9, 2007; and

     WHEREAS, the Parties now wish to resolve all existing and potential claims and outstanding obligations that may exist between DUSA and River’s Edge; and

     NOW, THEREFORE, the Parties, for good and sufficient consideration, the sufficiency of which is hereby acknowledged, agree as follows:

     1. Settlement Payment. River’s Edge shall make a one-time, lump sum settlement payment to DUSA in the aggregate amount of Four Hundred Twenty-Five Thousand Dollars U.S. ($425,000.00), which amount shall be wired to a bank account identified by DUSA. This Agreement shall not become binding or effective upon DUSA until this payment is made to and received by DUSA.

     2. Agreement To Discontinue Manufacture of NIC 750. As of the Effective Date, River’s Edge shall not, either directly or indirectly, manufacture, distribute, sell or offer to sell NIC 750 or any product containing nicotinamide and zinc that could be substitutable for Nicomide. Neither River’s Edge nor Brendan Murphy shall, either directly or indirectly or through any related or affiliated company, assist, cooperate with or provide any information to any third-party that is designed or intended to assist or enable the third-party to develop, manufacture, use, sell or offer for sale any product that infringes on the ‘468 Patent.

     3. Destruction of NIC 750 Not In the Distribution Chain. Without DUSA requiring a recall by River’s Edge of the NIC 750 product already in the distribution chain, River’s Edge shall destroy and provide to DUSA written confirmation of the destruction of all inventory of NIC 750 that is in its own warehouses or is otherwise within River’s Edge’s possession or control (i.e., 21,964 units in current inventory, together with 18,555 returned units). River’s Edge shall provide DUSA with the best available information that it has concerning the inventory of NIC 750 in the distribution chain at wholesalers and retail pharmacy warehouses, the amount of NIC 750 manufactured since its inception, the amount of any product returned, and any other information relevant to assist DUSA in determining the location and amount of NIC 750 in existence. Nothing in this Agreement shall be construed to require River’s Edge to recall NIC 750 product already in the distribution chain and DUSA shall take no action that is designed or intended to cause such a recall.

     4. NIC 750 In the Distribution Chain. River’s Edge shall be responsible for all costs and obligations arising from returns of NIC 750 from the distribution chain and/or order its destruction. If River’s Edge orders the destruction of any returns of NIC 750 from the distribution chain, it shall timely provide DUSA with a copy of the certificates of destruction or

other similar document that confirms that the NIC 750 returns have been destroyed. River’s Edge shall pay to DUSA $25.00 per unit for every bottle of NIC 750 above 5,000 units that is substituted after September 30, 2007. Should the cumulative number of prescriptions of NIC 750 filled, as tracked by DUSA utilizing Wolters Kluwer or if Wolters Kluwer does not track prescriptions of NIC 750 by like prescription service company for prescriptions filled by “All Physician/Specialties”, exceed such 5,000 units on a cumulative basis after September 30, 2007, DUSA will provide River’s Edge with written notice of such prescription information and make a demand for payment consistent with this provision. Said demands shall be made no more frequently than on a monthly basis. Payments for NIC 750 for any amounts due after September 30, 2007 will be due within ten (10) business days following River’s Edge’s receipt of the written demand thereof with a seven (7) business day grace period during which a written notice of default will be provided by DUSA to River’s Edge.

     5. Consent Judgment To Secure River’s Edge’s Payment Obligations Under Paragraph 4 of this Agreement. In order to secure payment of any amounts that may become due to DUSA under paragraph 4 of this Agreement, River’s Edge shall execute and deliver to DUSA’s counsel at the time of the execution of this Agreement a stipulated Consent Judgment, in the form attached hereto as Exhibit A, which shall provide for the payment by River’s Edge to DUSA of $25.00 per unit of NIC 750 substituted above 5,000 units as reported by Wolters Kluwer or other like prescription service company on a cumulative basis after September 30, 2007. DUSA’s counsel may file the stipulated Consent Judgment on the amount owed under Paragraph 4 of this Agreement if, and only if, River’s Edge fails to pay any amounts that may become due under Paragraph 4 of this Agreement after DUSA provides notice in compliance with Paragraph 4 of this Agreement.

In the event such stipulated Consent Judgment is filed, River’s Edge shall be entitled to a credit for any amounts already paid to DUSA pursuant to Paragraph 4 of this Agreement. In addition, at the time DUSA files and seeks the entry of the Consent Judgment it shall provide the Court with an affidavit that indicates, to the best of its knowledge, that the information in the stipulated Consent Judgment is true and correct.

     6. Consent Judgment To Secure River’s Edge’s Payment Obligations Under Paragraphs 11 and 12 of this Agreement. In order to secure payment of any amounts that may become due to DUSA under Paragraphs 11 and 12 of this Agreement, River’s Edge shall execute and deliver to DUSA’s counsel at the time of execution of this Agreement a stipulated Consent Judgment, in the form attached hereto as Exhibit B, which shall provide for the payment by River’s Edge to DUSA of the royalty payments provided for under the License Agreement between the Parties as contemplated in Paragraph 12 of this Agreement. DUSA’s counsel may file the stipulated Consent Judgment on the amount owed under the terms of the License Agreement should River’s Edge fail to pay DUSA the royalties as provided for in the License Agreement. The Consent Judgment identified in this Paragraph may not be filed for royalties over the minimum royalties unless and until any dispute concerning the amount owed is resolved in accordance with the dispute resolution procedure set forth in Paragraph 11.2 of the License Agreement. In the event such stipulated Consent Judgment is pursued, River’s Edge shall be entitled to a credit for any amounts already paid to DUSA pursuant to the License Agreement. In addition, DUSA shall provide an affidavit with the stipulated Consent Judgment indicating that, to its knowledge, the information in the stipulated Consent Judgment is true and correct.

     7. Validity of the ‘468 Patent. River’s Edge hereby expressly and unconditionally acknowledges that DUSA’s ‘468 Patent is valid and enforceable. River’s Edge shall accordingly issue a joint, agreed-upon press release that expressly states that the ‘468 Patent is valid and

enforceable. In accordance with Paragraph 15 hereunder, River’s Edge shall further execute a stipulated order of dismissal and final decision, in the form attached hereto as Exhibit C, which contains language that is intended to help DUSA effectuate a dismissal of the Inter Partes Reexamination of Patent No. 6,979,468 at the U.S. Patent and Trademark Office.

On the Effective Date of this Agreement, River’s Edge shall send the executed and mutually agreed-upon letter attached hereto as Exhibit D to First Data Bank, Medi-Span and Gold Standards indicating that River’s Edge has discontinued the manufacture and distribution of NIC 750, and that NIC 750 should be marked “OBSOLETE” on the respective databases. At the request of DUSA, River’s Edge will provide similar letters to ensure the delisting of NIC 750 from other similar databases identified by name and address by DUSA.

     9. River’s Edge’s Participation In Re-Examination of Patent. River’s Edge shall, within five (5) business days of the Effective Date of this Agreement and in consultation with counsel for DUSA, voluntarily withdraw and/or cease participation in the Inter Partes Reexamination of the ‘468 Patent at the U.S. Patent and Trademark Office.

     10. Return of Bond. River’s Edge shall not object, and if required shall specifically and unconditionally consent, to the return to DUSA of the entire bond, including any accrued interest, that was posted by DUSA in the context of the New Jersey Litigation and that is currently being held by the United States District Court, District of New Jersey.

     11. Grant of License to AVAR Products & Trademarks. DUSA shall grant, subject to the terms and conditions of the License Agreement mentioned below in Paragraph 12, River’s Edge a perpetual, exclusive license of all of DUSA’s rights, title and interest in and to its patent applications and know-how for the manufacture, sale and use of the AVAR cleanser, AVAR gel,

     21. Non-Disparagement. The Parties, and in the case of River’s Edge, Brendan Murphy, and in the case of DUSA, Robert Doman, agree that they shall not, now or ever in the future, publicly or privately, make, in any way, any disparaging, derogatory, unkind, unflattering or otherwise inflammatory remarks about the other party to any third party, including but not limited to the conduct, operations, financial condition or business practices of the other Party, the quality or condition of any products manufactured by River’s Edge, the quality or condition of any products manufactured by DUSA, any policies or procedures of the other Party, or the management personnel of the other Party.

This provision specifically excludes any comments made by any Party, or by Brendan Murphy, in the context of a communication protected by the attorney-client privilege or in the context of any filed litigation or regulatory proceeding. This provision shall not prevent a Party from responding truthfully to a subpoena or court order requiring testimony or documents consistent with Paragraph 20 above, but shall require the Party to provide the other Party with reasonable and practicable prior written notice if such disclosure involves and statements or comments that

fall within the scope of this provision. This provision shall survive expiration, termination and/or satisfaction of the terms of this Agreement.

This Agreement shall prevail over prior communications between the Parties or their representatives regarding the matters contained herein.

     23. No Waiver. The failure of either Party to enforce any provision of this Agreement at any time or for any period of time shall not be construed to be a waiver of any right of either Party hereunder nor to prevent the subsequent enforcement thereof or of any other provision hereof in accordance with its terms.

     24. Execution of Additional Documents. Each Party hereto agrees, without charge, to promptly execute and deliver such further applications, assignments, descriptions and other instruments and documents and otherwise to cooperate with the other Party as may be reasonably necessary or desirable to effect the purpose of this Agreement and carry out its provisions.

     27. Severability. If any provision of this Agreement, under any set of circumstances, whether or not foreseeable by the Parties, is hereafter held to be invalid, illegal or unenforceable in its present form and scope in any jurisdiction or proceeding, the remaining provisions of this Agreement shall continue to be given full force and effect, without regard to the invalid, illegal or unenforceable provision in such jurisdiction or proceeding, and shall be liberally construed in order to carry out the intentions of the Parties hereto as nearly as may be possible, and such holding shall not affect the validity, legality or enforceability of this Agreement in its entirety in any other jurisdiction or proceeding.

To the extent permitted by applicable law, River’s Edge and DUSA hereby waive any provision of law that would render any provision hereof prohibited or unenforceable in any respect.

          2.1.2 Except as expressly set forth in this Agreement, no license is granted by DUSA under its rights in any DUSA Technology whatsoever for any activities by River’s Edge that are outside the scope of the license grants in Section 2.1.1.

     2.2 Sublicensing. Sublicenses of the licenses granted to River’s Edge under Section 2.1.1 may be granted by River’s Edge; provided, however, in all cases, no sublicense granted by River’s Edge pursuant to this Section 2.2 shall be valid unless: (i) River’s Edge shall submit the proposed sublicense or distribution agreement to DUSA for written approval prior to execution, which approval shall not be unreasonably withheld or delayed; (ii) River’s Edge shall guarantee and be responsible for, as applicable, the performance of, or the making of all payments due and the making of any reports under this Agreement with respect to sales of Licensed Products by its Affiliates and Sublicensees and, in each case, the Affiliate’s and Sublicensee’s compliance with all applicable terms of this Agreement; (iii) such sublicense

Notwithstanding anything here and to the contrary, River’s Edge may enter into a sublicense agreement with Tiber Laboratories, LLC (“Tiber”) to allow Tiber to market the Licensed Products under Tiber’s label and NDC Number, provided that such agreement binds Tiber to all of the provisions of this Section 2.2; and further provided, that Tiber may not assign such agreement, or any obligations thereunder, without DUSA’s prior written consent.

     2.3 Trademarks. In addition, without any additional royalty payments by River’s Edge, DUSA hereby grants to River’s Edge a perpetual, exclusive license to all rights, title and interest that it owns or controls to the AVAR trademarks listed on Exhibit 2 attached hereto and made a part of this Agreement, and trade dress used in connection with the sale of Licensed Products (the “Trademarks”). The ownership and all goodwill from the use of the Trademarks shall vest in and inure to the benefit of River’s Edge. DUSA reserves all rights not expressly granted herein.

3. Royalties.

     3.1 Cumulative Sales Statement. For purposes of this Section 3.1, Net Sales shall be determined on a rolling 12 month basis for all Licensed Products. Together with the report set forth in Section 4.1.1 below, River’s Edge shall provide DUSA with a statement of cumulative 12-month Net Sales for each month.

     3.2 Royalty Payments to DUSA.

          3.2.1 As consideration to DUSA for the license and other rights granted to River’s Edge under this Agreement, River’s Edge shall pay to DUSA a guaranteed minimum royalty of Three Hundred Thousand Dollars ($300,000), to be payable as set forth in Section 4 below, said guaranteed minimum royalty to be paid to DUSA in all events, including if this Agreement is terminated or sales of the Licensed Products are ceased by River’s Edge, and credited against a royalty to be paid to DUSA on aggregate annual Net Sales of the Licensed Products in the amount of fifteen percent (15%) of all such Net Sales for the period of three (3) years commencing from the date of the First Commercial Sale by River’s Edge (the “Royalty Period”). Upon the payment of all royalties due during the Royalty Period, the license shall be fully paid.

          3.2.2 The Parties hereby acknowledge and agree that the Patent Rights, Trademarks and DUSA Know-How licensed pursuant to this Agreement justify royalties of differing amounts with respect to sales of the Licensed Products, which royalties could be applied separately to each Licensed Product involving the exercise of such Patent Rights and/or the incorporation of such DUSA Know-How, and that if such royalties

were calculated separately, royalties relating to the Patent Rights and royalties relating to the DUSA Know-How would last for different terms. In light of such considerations and for reasons of convenience, the Parties have hereby determined that blended royalty rates for the Patent Rights and the DUSA Know-How licensed hereunder will apply during a single royalty term and that the utilization of such blended royalty rates is advantageous to both Parties.

4. Payments And Reports.

     4.1 Payments.

          4.1.1 Within fifteen (15) days after the end of each calendar month beginning with the calendar month during which the Effective Date occurs, River’s Edge shall deliver to DUSA a report, summarizing the total gross sales of the Licensed Product(s), on a Licensed Product-by-Licensed Product basis, total Net Sales (including an itemization of the deductions applied to such gross sales to derive such Net Sales) during the relevant calendar month, and the calculation of royalties due thereon. The report for each calendar month shall also summarize the total gross sales of the Licensed Product(s), on a Licensed Product-by- Licensed Product basis, total Net Sales (including an itemization of the deductions applied to such gross sales to derive such Net Sales) during the relevant calendar month, and the calculation of royalties due thereon (together with the statement described in Section 3.1). Beginning with the first calendar month in which the First Commercial Sale of a Licensed Product is made by River’s Edge, and for each calendar month thereafter during the Royalty Period, royalty payments shall be made to DUSA within seventy-five (75) days following the end of each such calendar month (together with a copy of the report for the calendar month stated above). All other payments to be made under this Agreement shall be made in accordance with the terms set forth in the applicable Section(s) regarding such payments.

          4.1.2 Following the end of each year during the Royalty Period, the Parties shall reconcile (true-up) any adjustments in the last payment of each year. If the aggregate royalties for each year of the Royalty Period total less than One Hundred Thousand Dollars ($100,000) (the minimum annual royalty), then the payment for the last month in each year of the Royalty Period shall include the difference between One Hundred Thousand Dollars and all royalties paid during the first eleven calendar months of such year of the Royalty Period.

     4.2 Mode of Payment. All payments required under this Agreement shall be made in U.S. Dollars, regardless of the country(ies) in which sales are made, via wire transfer of immediately available funds as directed by DUSA from time to time. For the purposes of computing Net Sales of Licensed Product sold in a currency other than U.S. dollars, such currency shall be converted into U.S. dollars at an exchange rate equal to the buy rate of U.S. dollars published in the East Coast Edition of The Wall Street Journal for the last business day of the applicable calendar month. Such payments shall be without deduction of exchange, collection or other charges.

     4.3 Sales Records. Commencing with the First Commercial Sale of a Licensed Product, River’s Edge shall keep complete and accurate records pertaining to the sale of each Licensed Product sold during the first three years after the First Commercial Sale of a Licensed Product, in sufficient detail to permit DUSA to confirm the accuracy of the royalties paid by River’s Edge hereunder.  River’s Edge shall maintain such records for a period not less than three (3) calendar years after the year in which such sales occurred.

     4.4 Audits.

          4.4.1 At the request and expense of DUSA, River’s Edge shall permit DUSA, or its designee who shall be reasonably acceptable to River’s Edge, at reasonable times and upon reasonable written notice, (but no more often then once per calendar year unless (i) a deficiency of greater than five percent (5%) was determined by a prior audit, or (ii) an audit is required by DUSA’s independent registered accounting firm) to examine such records as may be necessary for the sole purpose of verifying the calculation and reporting of Net Sales and the correctness of any royalty made under this Agreement for any period within the preceding three (3) years. Any designee shall hold in confidence any confidential or proprietary information of River’s Edge, except that such accountant may disclose to DUSA the fact of a deficiency, the lack of a deficiency or any overpayment, and the degree thereof, including the dollar amount. All results of any such examination shall be made available to River’s Edge.

          4.4.2 In the event that any audit reveals an under-payment in the amount of any royalties that should have been paid by River’s Edge to DUSA in accordance with this Agreement, then such amount shall be paid within ten (10) days after DUSA makes a demand therefor, plus interest thereon. Such interest shall be calculated from the date such amount was due until the date such amount is actually paid, at the rate of three percent (3%) over the prime rate of interest reported in the East Coast Edition of The Wall Street Journal for the date such amount was due. In addition, if the underpayment is in excess of five percent (5%) of the amount that actually should have been paid, then River’s Edge shall reimburse DUSA for the cost of the audit.

     4.5 Taxes. In the event that River’s Edge is mandated under the laws of a country to withhold any tax, tariff, levy or similar charge (“Taxes”) to the tax or revenue authorities in such country in connection with any payment to DUSA, such Taxes shall be paid in the first instance by River’s Edge so that DUSA receives the gross amounts due under this Agreement. If for any reason River’s Edge has not such paid such Taxes, and DUSA becomes obligated to advance any such Taxes, then DUSA shall invoice River’s Edge for such Taxes and payment shall be made by River’s Edge within ten (10) business days in accordance with Section 4.2 above. DUSA shall secure and promptly send to River’s Edge proof of any such Taxes paid or required to be withheld by DUSA for the benefit of River’s Edge. The Parties shall cooperate reasonably with each other to ensure that any amounts required to be withheld by DUSA are reduced in amount to the fullest extent permitted by law. No deduction shall be made, or a reduced amount shall be deducted, if River’s Edge furnishes a document from the appropriate tax authorities to DUSA certifying that the payments are exempt from withholding Taxes or subject to reduced tax rates, according to the applicable convention for the avoidance of

double taxation. DUSA shall be responsible for DUSA’s income tax liability attributable to royalty payments received by DUSA under this Agreement.

Each Party shall be responsible for their own returns of Licensed Product from its own customers; provided, however, the Parties recognize that, in some instances, it may be difficult for customers to determine the seller with respect to the batches of on-hand inventory being shipped by DUSA to River’s Edge. Therefore, with respect to returns of the split batches of each of the Licensed Products that is being shipped to River’s Edge by DUSA, River’s Edge shall be responsible for any returns of the Licensed Product to DUSA which exceeds DUSA’s pro rata share of sales to customers common to both Parties of Licensed Products from such split batches.

DUSA shall pay all costs and expenses of filing, prosecuting and maintaining such Patent Rights, and, subject to Section 6.2.4, agrees to expend commercially reasonable efforts to diligently prosecute the patent applications listed on Exhibit 1.

          6.2.2 If DUSA elects not to pay for the further prosecution or maintenance of any Patent Rights Covering any Licensed Products, or the filing of any divisional or continuing patent application (based on a prior patent application or patent) listed on Exhibit 1, DUSA shall notify River’s Edge in writing in a timely manner and River’s Edge may do so at its expense. In the event that River’s Edge elects to proceed with any such filing, prosecution or maintenance, DUSA shall assign its rights in and to such Patent Rights to River’s Edge, and, subject to Section 10.4.2, all of DUSA’s rights in such Patent Rights shall cease.

          6.2.3 Each Party agrees to cooperate with the other Party to execute all lawful papers and instruments, to make all rightful oaths and declarations, and to provide consultation and assistance as may be necessary in the preparation, prosecution, maintenance and enforcement of all such patents. DUSA specifically agrees to cooperate with River’s Edge should it choose to publicly record their license interest in the Patent Rights, should a patent issue thereon. Furthermore, DUSA agrees to cooperate with River’s Edge should River’s Edge choose to publicly record its interest in the Trademarks.

          6.2.4 DUSA specifically and expressly makes no representation or warranty that any claims will ultimately be allowed, or patents will ultimately issue within the Patent Rights.

     6.3 Patent and Trademark Enforcement.

          6.3.1 If either Party learns of an infringement, unauthorized use, misappropriation or ownership claim or threatened infringement or other such activity (an “Infringement”) by a Third Party with respect to the Licensed Products, such Party shall promptly notify the other Party in writing and shall promptly provide such other Party with available evidence of such Infringement.

          6.3.2 DUSA shall have the first right, but not the duty, to institute, prosecute, and control any action or proceeding with respect to an Infringement based on any DUSA Technology. If DUSA (or its designee) does not secure actual cessation of such infringement or institute an infringement proceeding against an offending Third Party within thirty (30) days after a receipt of evidence of the Infringement, River’s Edge shall have the right, but not the duty, to institute, prosecute, and control any action or proceeding with respect to such Infringement. The costs and expenses of any such action (including fees of attorneys and other professionals) shall be borne by the Party instituting the action, or, if the Parties elect to cooperate in instituting and maintaining such action, such costs and expenses shall be borne by the Parties in such proportions as they may agree in writing. Each Party shall execute all necessary and proper documents, take such actions as shall be appropriate to allow the other Party to institute, prosecute, and control such Infringement actions and shall otherwise cooperate in the institution and prosecution of such actions (including, without limitation, consenting to being named as a nominal party thereto). Any award, damages or other monetary awards recovered (whether by way of settlement or otherwise) shall be applied first to reimburse both Parties for all costs and expenses incurred by the Parties with respect to such action on a

pro rata basis and, if after such reimbursement any funds remain from such award, they shall be allocated as follows: (A) if DUSA has instituted and maintained such action alone, DUSA shall be entitled to retain such remaining funds; (B) if River’s Edge has instituted and maintained such action alone, River’s Edge shall be entitled to retain such remaining funds, but shall pay DUSA a royalty, as if such remaining funds constituted Net Sales made within the month the funds are received; or (C) if the Parties have cooperated in instituting and maintaining such action, the Parties shall allocate such remaining funds between themselves in the same proportion as they have agreed to bear the expenses of instituting and maintaining such action.

     6.4 Infringement Action by Third Parties. In the event of the institution or threatened institution of any suit by a Third Party against either Party for patent or trademark infringement involving the use, manufacture, sale, offer for sale, distribution or marketing of a Licensed Product, the Party being sued shall promptly notify the other Party in writing of such suit.

     6.4.1 If the suit alleges any claim for damages where the damages could be based on DUSA’s use, manufacture, sale, offer for sale, distribution or marketing of a Licensed Product prior to the Effective Date, each Party may engage counsel of its choice and appear and represent its own interests in the suit, at its own expense. If both Parties are not named as parties to the suit, then the named Party will cooperate with the other Party to take whatever action is appropriate in the circumstances to add the other as a party. River’s Edge agrees to assist and cooperate with DUSA in the defense of any patent or trademark infringement suit related to the Licensed Products in which River’s Edge is not named and declines to participate in the defense.

     6.4.2 Unless otherwise covered in Sections 6.3.2 or 6.4.1, River’s Edge shall defend any other patent or trademark infringement suit instituted by a Third Party against River’s Edge involving the use, manufacture, sale, offer for sale, distribution or marketing of a Licensed Product only after the Effective Date, at its own expense and shall be responsible for all damages incurred as a result thereof.

The restrictions contained in Section 9.2 shall not apply to Confidential Information that: (i) is provided by the receiving Party to Third Parties under confidentiality agreements having provisions at least as stringent as those in this Agreement, for consulting, manufacturing development, manufacturing, external testing, marketing trials and to Third Parties who are sublicensees or other development/marketing partners hereunder with respect to any of the subject matter of this Agreement; (ii) is otherwise required to be disclosed in compliance with applicable laws or regulations (including, without limitation and for the avoidance of doubt, the requirements of the U.S. Securities and Exchange Commission, Nasdaq or any other stock exchange on which securities issued by a Party are traded) or order by a court or other regulatory body having competent jurisdiction; provided, that, if a Party is required to make any such disclosure of the other Party’s Confidential Information such Party will give reasonable advance written notice to the disclosing Party of such disclosure requirement and, except to the extent inappropriate in the case of patent applications, will use its best efforts to secure confidential treatment of such Confidential Information required to be disclosed; or (iii) was developed by the receiving Party independent of any disclosure received under this Agreement.

comparable coverage, up to and beyond the expiration or termination of this Agreement during (i) the period that any Licensed Product is being commercially distributed or sold by the Party, its Affiliates or Sublicensees, and (ii) a commercially reasonable period thereafter.

11.

Term; Termination.

     11.1 Term. This Agreement shall become effective as of the Effective Date and, unless earlier terminated pursuant to any other provisions of this Section 11, shall expire:

     11.1.1 upon the later of: (1) the expiration of the last to expire of all Patent Rights Covering the Licensed Product ; or (2) ten (10) years from the First Commercial Sale of such Licensed Product; and

     11.1.2 in its entirety upon the expiration of this Agreement with respect to all Licensed Products in the Territory (the “Term”).

     11.2 Termination for Cause. Either Party (the “Non-breaching Party”) may terminate this Agreement, without prejudice to any other remedies available to it at law or in equity, in the event the other Party (the “Breaching Party”) shall have materially breached or defaulted in the performance of any of its material obligations hereunder and such breach or default shall have continued for thirty (30) days after written notice thereof was provided to the Breaching Party by the Non-breaching Party (or, if such breach or default cannot be cured within such thirty (30)-day period, if the Breaching Party does not commence and diligently continue actions to cure such breach or default during such thirty (30) days). Any such termination under this Section 11.2 shall become effective at the end of such thirty (30)-day period unless the Breaching Party has cured any such noticed breach(es) or default(s) prior to the expiration of such thirty (30)-day period (or, if such breach(es) or default(s) cannot be cured within such thirty (30)-day period, if the Breaching Party has commenced and diligently continued actions to cure such breach(es) or default(s)). The right of either Party to terminate this Agreement as provided in this Section 11.2 shall not be affected in any way by its waiver or failure to take action with respect to any previous breach or default.

     11.2.1 In the event that River’s Edge fails to pay to DUSA the guaranteed minimum annual royalties which are due and payable under Sections 4.1.2 hereof, then DUSA shall be entitled to file the consent judgment provided for in Paragraph 5 of the Settlement Agreement and Mutual Release entered into by DUSA and River’s Edge on the date hereof for the balance due.”  

     11.2.2  Any dispute over the amount of royalties due beyond the guaranteed minimum annual royalties shall be resolved by submission to a single independent neutral reviewer, to be selected by the Parties.  Such review may be commenced by River’s Edge by notice to DUSA within 10 days of receipt of written notice from DUSA that additional royalties are claimed to be due and which shall include River’s Edge’s suggested independent neutral review.  The reviewer must be a certified public accountant, must have substantial experience in the pharmaceutical industry, and must hold an equity interest in an accounting firm of national repute.  If the parties cannot agree, the reviewer

will be chosen by JAMS in Newark, New Jersey upon request of any Party.  Within ten days of selection of the reviewer, each Party shall submit a statement of its position to the reviewer, with any supporting evidence.  Five business days after submission of the opening statements, each Party may submit a reply to the other’s statement.  The reviewer shall announce a decision within ten days of the date for submission of reply statements. If the reviewer confirms a previous audit by DUSA, then the reviewer shall be paid by River’s Edge. If the reviewer determines that DUSA’s audit was erroneous by more than 5%, then DUSA shall pay for the cost of the reviewer. In all other cases, the Parties shall split the cost of the reviewer equally.

     11.3 Termination for Challenges. In the event that River’s Edge or any of its Affiliates or Sublicensees make any request for, or file a declaration of, or undertake any action involving, any interference, opposition, challenges as to ownership, assertions of invalidity or unenforceability, revocation or reexamination relating to any DUSA Technology before any court, agency or other tribunal, then DUSA shall have the right to immediately terminate this Agreement by sending written notice of such termination to River’s Edge.

     11.4 Effect of Expiration or Termination.

     11.4.1 Following the expiration of the term of this Agreement with respect to a Licensed Product in any country in the Territory pursuant to Section 11.1, River’s Edge shall have a non-exclusive, royalty-free, paid-up, perpetual, irrevocable and sublicensable right and license, to develop, make, have made, use, market, sell, have sold, offer for sale, import, distribute and otherwise exploit such Licensed Product in the such country in the Territory. To that end, River’s Edge may hold and use all data, reports, records, information and materials that relate to such Licensed Product and may in its sole discretion continue or grant any sublicense granted by it under this Agreement.

     11.4.2 If this Agreement is terminated in its entirety by DUSA pursuant to Section 11.2 or Section 11.3, in addition to any other remedies available at law or in equity: (A) all licenses and rights granted by DUSA to River’s Edge under this Agreement shall terminate; (B) at River’s Edge’s expense, River’s Edge shall promptly: (1) license on a non-exclusive basis to DUSA all River’s Edge patent rights related to the Licensed Products; (2) license on a non-exclusive basis (subject to continuing use by River’s Edge for other products if already in use for such other products) and transfer to DUSA all relevant River’s Edge Know-How, data, reports, records and materials relating to the Licensed Products; and (3) return to DUSA all relevant records and materials in River’s Edge’s possession or control containing DUSA’s Confidential Information (provided that River’s Edge may keep one (1) copy of such Confidential Information for archival purposes only); (C) to the extent River’s Edge owns or holds any right, title and interest in any Trademarks, trade names, and logos under which a Licensed Product has been or is being marketed or sold in the Territory, River’s Edge shall license the same to DUSA on a non-exclusive basis; and (D) all sublicenses granted by River’s Edge under this Agreement shall continue in full force and effect in accordance with the terms and conditions of the respective sublicense agreements, and River’s Edge will assign to DUSA all such sublicense agreements.

     11.5 Accrued Rights; Surviving Obligations.

     11.5.1 Termination, relinquishment or expiration of this Agreement for any reason shall be without prejudice to any rights that shall have accrued to the benefit of any Party prior to such termination, relinquishment or expiration including, without limitation, any payment obligations under Section 4 and any and all damages arising from any breach hereunder.

     11.5.2 In addition to the provisions of this Agreement which expressly survive as set forth elsewhere in this Agreement, all of the Parties’ rights and obligations under, and/or the provisions contained in, Sections 1, 3.2, 5.4, 6.4, 7 (provided that DUSA shall be responsible for regulatory obligations relating to any Licensed Product it may sell after the expiration, termination, or relinquishment of this Agreement), 9, 10, 11.4, 11.5, 13.3, 13.5, 13.6, 13.8, 13.11, 13.13, 13.15. shall survive the expiration, termination, or relinquishment of this Agreement.

     11.6 Section 365(n) of the Bankruptcy Code. All rights and licenses granted under or pursuant to any Section of this Agreement are and shall otherwise be deemed to be for purposes of section 365(n) of Title 11, of the United States Code (the “Bankruptcy Code”) licenses of rights to “intellectual property” as defined in section 101(56) of the Bankruptcy Code. The Parties shall retain and may fully exercise all of their respective rights and elections under the Bankruptcy Code. Upon the bankruptcy of any Party, the non-bankrupt Party shall further be entitled to a complete duplicate of, or complete access to, any such intellectual property, and such, if not already in its possession, shall be promptly delivered to the non-bankrupt Party, unless the bankrupt Party elects to continue, and continues, to perform all of its obligations under this Agreement.

12. Force Majeure.

Any delay in the performance of any of the duties or obligations of either Party hereto (except the payment of money due hereunder) shall not be considered a breach of this Agreement, and the time required for performance shall be extended for a period equal to the period of such delay, if such delay has been caused by or is the result of acts of God; acts of public enemy; insurrections; riots; injunctions; embargoes; labor disputes, including strikes, lockouts, job actions, or boycotts; fires; explosions; earthquakes; floods; shortages of energy; governmental prohibition or restriction; or other unforeseeable causes beyond the reasonable control and without the fault or negligence of the Party so affected.

Except pursuant to a sublicense permitted under this Agreement, neither Party shall be entitled to assign its rights or delegate its obligations hereunder without the express written consent of the other Party hereto, except that each Party may assign its rights and transfer its duties hereunder to any assignee of all or substantially all of its business (or that portion thereof to which this Agreement relates) or in the event of such Party’s merger, consolidation or involvement in a similar transaction.
