As soon as either party becomes aware of a Latent Defect in any Light Source it shall immediately notify the other party as to the serial number(s) of the Light Source(s) involved, which at DUSA's election, shall be deemed rejected as of the date of such notice. NBC agrees to repair or replace all Light Sources so involved at its expense. For purposes of this Section 3.4, "defect" shall mean that a Light Source fails to conform to the warranties given by NBC herein; however, "defect" for purposes of the foregoing, shall exclude defects in the design of the Output Regulating Circuitry System, the Plastic Housing and the Stand. 7 3.5 Presence At Facility. Upon at least [c.i.] prior written notice given by DUSA to NBC, DUSA shall have the right to assign a reasonable number of employees or consultants of DUSA to inspect and audit the Facility at which Light Sources are manufactured in order to verify NBC's compliance with QS and other agreed requirements, provided, however that (i) such employees or consultants shall not unreasonably interfere with other activities being carried out at the Facility, (ii) that such employees or consultants shall observe all rules and regulations applicable to visitors and to individuals employed at the Facility, and (iii) such employees or consultants agree to maintain the Confidential Information of NBC in accordance with Article 11 below. 3.6 Changes. DUSA shall have the right to modify the Specifications from time to time. All such modifications shall be in writing and shall be signed by an authorized representative of DUSA and NBC, and shall be effective for orders of applicable units placed after such notice. If such modifications result in a material change [c.i.] as shown by documentation provided by NBC, the parties shall agree upon an appropriate corresponding [c.i.] of the Light Sources hereunder; and if such modifications result in a delay in delivery, the parties shall negotiate a reasonable extension of the affected lead times. ARTICLE 4 SUPPLY OUTSIDE THE TERRITORY ---------------------------- From time to time as DUSA desires to secure supply of Light Sources for sale in area(s) outside of the Territory (collectively, the "New Area(s)"), DUSA agrees to provide notice to NBC regarding the possibility of NBC providing some or all of such supply ("Notice"). Within [c.i.] after receiving the Notice, NBC shall notify DUSA whether or not NBC so desires to discuss the possibility of supplying DUSA such Light Sources for any particular New Area(s) designated by DUSA in the Notice. If NBC desires, the parties shall negotiate in good faith for a period of [c.i.] the terms and conditions pursuant to which NBC would supply Light Sources to DUSA for sale for the New Area(s) so designated outside of the Territory. If NBC does not desire to provide such supply or the parties are unable to agree on the terms and conditions of such supply, after such [c.i.] period DUSA shall be free to secure one or more alternate sources for its requirements of Light Sources for such New Area(s) outside the Territory (including manufacturing such Light Sources itself), without any further obligation to NBC with respect to such New Area(s) so designated.

In any such event, NBC shall provide to DUSA or its designee copies of all documentation within NBC's control that is reasonably necessary for DUSA to exercise the Manufacturing License, and shall reasonably cooperate with DUSA to establish supply of Light Sources, including sources of components and other materials. In the event that DUSA has Light Sources manufactured by a third party, DUSA shall obtain from such third party a written confidentiality agreement to protect against the unauthorized use and disclosure of NBC's Confidential Information. 5.2.2.1 Failure to Supply. If for any [c.i.] NBC fails to supply quantities of Light Sources (including those units placed in inventory pursuant to Sections 2.3.3 or 2.3.4) ordered in accordance with Section 2.3 above, then DUSA may manufacture or have manufactured Light Sources for sale or other distribution in the Territory for use in applications within the Field pursuant to the Manufacturing License. Without limiting the foregoing, if [c.i.] or more of the [c.i.] units of Light Source delivered hereunder or [c.i.] or more of the Light Sources supplied in [c.i.] during any [c.i.] period fail to conform to Specifications, the same shall be deemed a failure to supply for purposes of this Section 5.2.2.1; provided, however, where it can be shown that a particular Light Source failure to conform is a result of damage during shipping rather than a failure to manufacture in Specification, then such Light Source shall not be deemed to fail to conform to Specifications for purposes of the foregoing and therefore shall not be considered a failure to supply under this Section 5.2.2.1. Notwithstanding anything in this Agreement to the contrary, if NBC's failure to supply hereunder is as a result of a Force Majeure Event then DUSA's right to manufacture Light Sources under this Section 5.2.2.1 shall continue until such time as NBC provides DUSA with [c.i.] written notice of NBC's desire to resume manufacturing and reasonably demonstrates to DUSA that it is able to adequately supply DUSA's requirements of Light Sources and there after until (i) to the extent DUSA contracts with a third party to supply Light Sources, for the remaining noncancellable period of such contract, or (ii) to the extent DUSA manufactures Light Sources itself, for a period of [c.i.] after DUSA commenced manufacturing of such Light Sources, and thereafter, at such time as NBC [c.i.] by DUSA to establish such internal manufacturing capacity, unless DUSA is able to redeploy such manufacturing capacity, in which event NBC shall [c.i.] to redeploy such manufacturing capacity (it being understood that, if so requested, DUSA will use reasonable efforts to so redeploy such manufacturing capacity), and (B) DUSA's [c.i.] to establish such manufacturing capacity for such redeployed use. For purposes of the foregoing, DUSA's [c.i.] shall be determined in good faith. 5.2.2.2 Outside the Territory. Except as otherwise agreed, upon expiration of the [c.i.] period as required in Article 4 above, DUSA may manufacture or have manufactured Light Sources for sale or other distribution for the New Area(s) so designated in DUSA's Notice for use in applications within the Field pursuant to the Manufacturing License. 9 5.2.2.3 Termination. If NBC terminates this Agreement pursuant to Section 10.3 below or DUSA terminates this Agreement pursuant to Section 10.2 below (for breach by NBC), then DUSA may manufacture or have manufactured Light Sources for sale or other distribution worldwide for use in applications within the Field pursuant to the Manufacturing License. To the extent that DUSA elects to exercise its rights under this Section 5.2 with respect to supply within the Territory, (i) DUSA shall be relieved of its obligations under Sections 2.1, 2.2 and 2.3 and (ii) notwithstanding anything in this Agreement to the contrary DUSA's sole remedy shall be the exercise of such rights and DUSA shall not be entitled to sue for damages or seek any other remedy against NBC resulting from NBC's failure to supply hereunder.

NBC may offer extended warranty service contracts to end-users of the Light Sources supplied hereunder. Such contracts shall be on reasonable and customary terms and conditions for services of a similar nature and shall not be any less favorable to the end-users of the Light Sources supplied hereunder than other end-users of other products manufactured by NBC. It is understood and agreed that DUSA may contract with third parties to provide extended warranty or out-of-warranty service for Light Sources or may provide such service itself. 8.5 Out-of-Warranty Service; Spare Parts. NBC hereby undertakes to maintain repair capability for Light Sources during the term of this Agreement and for [c.i.] thereafter (the "Support Period") subject to its ability to source applicable components from third parties. In accordance with the foregoing, NBC shall, if requested by DUSA, provide out-of-warranty service on reasonable and customary terms and conditions. In addition during the Support Period, NBC agrees to [c.i.] DUSA and its designees spare and replacement parts [c.i.] and lead times therefor as may be required to service and maintain Light Sources. Where there are no such [c.i.], such spare or replacement parts shall be provided [c.i.] and lead times, and in any event NBC's prices, terms and conditions for providing services under this Section 8.5 shall be no less favorable to the customer than those offered by NBC to a third party for similar services or parts. Notwithstanding the foregoing, neither DUSA nor its customers shall have any obligation to order any such service, or spare or replacement parts from NBC. 8.6 Epidemic Failures. In addition to and without limiting the warranties given above, where a defect in the design (excluding the design of the Output Regulating Circuitry System, Plastic Housing or Stand) of the Light Sources which effects a minimum of [c.i.] of the total units of any particular Light Source model (by SKU number) supplied hereunder (an "Epidemic Failure"), NBC shall, at its expense, and in a reasonable time period, remedy such Epidemic Failure in all units of such Light Source model (previously supplied or to be supplied hereunder). 8.7 Recalls. In the event that DUSA is required by any regulatory agency to recall the Light Sources or if DUSA voluntarily initiates a recall of the Light Sources and in either case such recall is a result of a breach of any of the warranties under Section 8.1.1 through 8.1.3 above, NBC shall bear the direct costs of such recall. In addition, NBC agrees to cooperate with and assist DUSA in locating and retrieving, if necessary, Light Sources recalled for any reason. A recall of DUSA's products (including the Light Sources) for reasons other than those set forth in this Section 8.7 (including reasons due to force majeure) above shall not affect DUSA's obligation to purchase 13 Light Sources in accordance with Article 2 herein above, as may be modified, or DUSA's obligation under any outstanding purchase order hereunder. 8.8 Documentation. NBC agrees to develop and provide to DUSA documentation describing routine maintenance, service and care of the Light Sources. In addition, upon DUSA's request, NBC agrees to provide DUSA such other information and documentation as DUSA may reasonably require in order to fulfill standard maintenance and support requirements on reasonable and customary terms and conditions. ARTICLE 9 TRADEMARKS ---------- 9.1 Packaging and Labeling. The trade dress, style of packaging and the like with respect to the Light Sources will be determined by DUSA in consultation with NBC so as to be consistent with DUSA's standard trade dress and style (the "Packaging Specifications"). NBC shall be responsible for packaging and labeling the Light Sources delivered hereunder in accordance with the Packaging Specifications and all applicable regulatory requirements. 9.2 Trademarks. Without limiting the provisions of Section 9.1 above, packaging materials and labels for the Light Sources shall display the Blu-U Trademark and the DUSA trade name (collectively, the "DUSA Marks"). Accordingly, DUSA hereby grants to NBC a license to use the DUSA Marks for the term of this Agreement for the purposes of supplying the Light Sources hereunder. The ownership and all goodwill from the use of the DUSA Marks shall vest in and inure to the benefit of DUSA. NBC hereby acknowledges DUSA's ownership rights in the DUSA Marks, and accordingly agrees that at no time during or after the term of this Agreement to challenge or assist others to challenge the DUSA Marks or the registration thereof or attempt to register any trademarks, marks or trade names confusingly similar to such DUSA Marks. 9.3 Recordation. In those countries of the Territory where a trademark license must be recorded, DUSA will provide and record a separate trademark license for the DUSA Marks. NBC shall cooperate in the preparation and execution of such documents [c.i.]. ARTICLE 10 TERM AND TERMINATION -------------------- 10.1 Term. The term of this Agreement shall commence on the Effective Date and continue in full force until the tenth anniversary of the Effective Date, unless terminated earlier in accordance with this Article 10. This Agreement may be extended for an additional period by mutual written agreement of NBC and DUSA at least six (6) months prior to expiration of the then-current term hereof; provided, however, that neither NBC nor DUSA shall be obligated to approve any such extension and shall have no liability whatsoever by reason of any failure to agree on any such extension. 10.2 Breach. This Agreement may be terminated by either party if the other party breaches any material term or condition of this Agreement and fails to remedy the breach within [c.i.] after being given written notice thereof. Notwithstanding the foregoing, in the event of breach by either party, the other party's right to terminate shall be stayed if the breaching party 14 proposes a mutually agreeable plan to remedy such breach within [c.i.] period and remedies such breach within [c.i.] after being given written notice thereof. It is understood and agreed that this Section 10.2 is subject to the provisions of Section 14.3 below, excusing performance where performance is rendered impossible due to a Force Majeure Event, including without limitation failure of suppliers, in each case where such failure is beyond the reasonable control of the nonperforming party. For avoidance of doubt, among other things a delay by NBC of more than [c.i.] of the delivery date of any shipment of Light Sources ordered in accordance with Section 2.3 shall be deemed material. 10.3 Convenience. Either party may terminate this Agreement upon twelve (12) months' prior written notice to the other party, provided, however such notice may not be given prior to the third anniversary of the Effective Date. 10.4 Termination for Insolvency. Either party may terminate this Agreement if the other becomes the subject of a voluntary or involuntary petition in bankruptcy or any proceeding relating to insolvency, receivership, liquidation, or composition or the benefit of creditors, if that petition or proceeding is not dismissed with prejudice [c.i.] after filing. 10.5 Survival. It is understood that termination or expiration of this Agreement shall not relieve a party from any liability which, at the time of such termination or expiration, has already accrued to the other party. The provisions of Sections 5.2, 8.1, 8.2, 8.3, 8.5, 8.6, 8.7 and 10.5 and Articles 1, 11, 13 and 14 shall survive the termination of this Agreement for any reason. Except as otherwise expressly provided in this Article 10, all other rights and obligations of the parties shall terminate upon termination of this Agreement.

Friedman Subject: Pricing - Blu-U 4170 Date: 9/24/98 Pricing for the Blu-U [c.i.] is listed below. Please note that this pricing is at best only [c.i.], and, therefore, should not be considered [c.i.]. In addition, pricing [c.i.] does not include [c.i.], as it is impossible to establish pricing without a finished good. Also, several items, such as the [c.i.] DUSA [c.i.], and the item marked [c.i.] in the DUSA provided bill of materials are not quoted due to lack of sufficient information. Finally, pricing quoted is based [c.i.] as supplied to National Biological. Since neither DUSA or NBC is able to validate the accuracy of such bill until [c.i.], errors of omission, as well as costing errors by DUSA may have occurred which cannot at this time be accounted for, National Biological cannot therefore rely on these [c.i.] for any purposes other than [c.i.]. The following is our estimated cost to DUSA and, subject to the language in the P&S Agreement, may be used in the contract.
