Licensor hereby grants to Licensee an ---------------- exclusive, worldwide license to use, make, have made and sell all products and/or processes utilizing the Licensed Technology, with the full right to grant sublicenses, subject to the terms of this Agreement. 2.2 Reimbursement of Patent Costs. As a part of the consideration ----------------------------- for the exclusive license granted pursuant to Section 2.1 hereof, Licensee shall reimburse Licensor for Licensor's out-of-pocket costs incurred for patent attorney fees and patent application filing fees in connection with the Licensed Patents, up to an aggregate maximum of $25,000. Such reimbursement shall be subject to Licensor's presentation of appropriate documentation of Licensor's payment of such expenses. -3- <PAGE> No payment shall be payable by Licensee hereunder unless and until the issue of the validity of the claims as now stated in the Licensed Patents as described in Section 3.1 hereof is resolved favorably to Licensor's reasonable satisfaction, or, upon the expiration of one (1) year after the date of this Agreement if no request for re-examination of the Licensed Patents is made within such period. All payments made by Licensee to Licensor pursuant to this Section 2.2 shall be credited against Licensee's obligation to pay royalties as set forth in Section 2.3 hereof. 2.3 Royalties. --------- 2.3.1 Percentage Royalty. As additional consideration for ------------------ the exclusive license granted pursuant to Section 2.1 hereof, Licensee shall pay to Licensor a continuing royalty on a country-by-country basis in the amount of (i) three percent (3%) of Net Sales of Licensed Products made, used or sold in any country where the Licensed Technology utilized therein is protected by a valid patent. 2.3.2 Credits Against Royalties. Licensee shall be entitled ------------------------- to a credit against royalties payable hereunder in an amount equal to the payments made by Licensee under Sections 2.2 and 3.4 hereof. 2.3.3 Minimum Annual Royalty. From and after January 1, ---------------------- 1997, Licensee shall pay to Licensor minimum annual royalties as set forth herein. The minimum annual royalty for the calendar year 1997 shall be $20,000. For the three years thereafter, the minimum annual royalty for each subsequent calendar year shall increase by $10,000, such that for all years after and including the calendar year 2000, the minimum annual royalty shall be $50,000. Any percentage royalties accrued and paid to Licensor (but not taken as a credit pursuant to Section 2.3.2 hereof) for any calendar year shall be credited against the minimum royalty payable for such calendar year. The payment of any shortfall between actual royalties paid and the minimum annual royalty applicable to such calendar year shall be payable to Licensor within sixty (60) days after the last day of such calendar year. Licensor's sole remedy for any failure by Licensee to pay the minimum annual royalty required hereunder shall be to convert the exclusive license granted hereunder to a nonexclusive license upon the expiration of sixty (60) days' written notice of Licensor's intention to so convert the license, without Licensee's payment of any delinquent minimum annual royalty. Such conversion would not relieve Licensee from payment of royalties as described in Section 2.3.1. 2.3.4 Most Favored Licensee. If this license becomes non- --------------------- exclusive and if Licensor grants a license to use the Licensed Patents to any third party at a royalty rate lower than three percent (3%), then the royalty rate payable by -4- <PAGE> Licensee under this Agreement shall be reduced to the same rate payable by the third party. 2.4 Combination Product. ------------------- 2.4.1 Definition of Combination Product. As used herein, the term "Combination Product" shall mean a Licensed Product which cannot be manufactured, used or sold without (i) infringing the Licensed Patents, and also (ii) infringing one or more patents held by Licensee or a third party (referred to herein as "other patent rights"). 2.4.2 Net Sales of Combination Product. The Net Sales -------------------------------- of a Combination Product shall be determined in accordance with the following formula: A X = - x C B , where X = the Net Sales attributable to the portion of the Combination Product which is attributable to the Licensed Patents, on which Net Sales Licensee shall pay the royalty rate set forth in Section 2.3.1; and A = the value of the contribution of the Licensed Patents (as compared to the value of the contributions of the rights) used in the Combination Product; and B = The aggregate value of all patent rights used for the Combination Product, consisting of both the Licensed Patents and all other patent rights used in the Combination Product; and C = the Net Sales for the Combination Product. The values described above shall be determined by the parties hereto in good faith. In the absence of agreement as to said values, the values shall be determined by arbitration in accordance with the provisions of Section 10.2 hereof. 2.5 Component Product. ----------------- 2.5.1 Definition of Component Product. As used herein, ------------------------------- the term "Component Product" shall mean a Licensed Product which is a distinct component of a product which contains multiple components (including, as an example of additional components, proprietary methods sold or licensed with the Component Product). -5- <PAGE> 2.5.2 Net Sales of Component Product. The Net Sales of a ------------------------------ Component Product shall be determined in accordance with the following formula: A X = - x C B , where X = the Net Sales attributable to the Component Product, on which Licensee is obligated to pay the royalty rate set forth in Section 2.3.1; and A = the value of the Component Product, based upon costs to manufacture the Component Product, or the sales price of the Component Product if it is sold separately; and B = The value of the aggregate product, with all components (including methods sold or licensed with the Component Product), including the Component Product, based upon the same criteria as used for A above; and C = the Net Sales for the aggregate product. The values described above shall be determined by the parties in good faith. In the absence of agreement as to said values, the values shall be determined by arbitration in accordance with the provisions of Section 10.2 hereof. 2.6 Quarterly Payments. ------------------ 2.6.1 Sales by Licensee. With regard to Net Sales made ----------------- by Licensee or its Affiliates, royalties shall be payable by Licensee quarterly, within ninety (90) days after the end of each calendar quarter, based upon Net Sales of Licensed Products during such preceding calendar quarter, commencing with the calendar quarter in which the first commercial sale of any Licensed Product is made. 2.6.2 Sales by Sublicensees. With regard to Net Sales --------------------- made by sublicensees of Licensee or its Affiliates, royalties shall be payable by Licensee quarterly, within one hundred twenty (120) days after the end of each calendar quarter, based upon the Net Sales of Licensed Products by such sublicensee during such preceding calendar quarter, commencing with the calendar quarter in which the first commercial sale of any Licensed Product is made by such sublicensee. 2.7 Term. The term of this Agreement and the license granted ---- hereunder shall commence on the date set forth in the preamble paragraph of this Agreement, and unless sooner -6- <PAGE> terminated by Licensee upon delivery of thirty (30) days' written notice or in accordance with the provisions of Section 8.1 hereof, the term of this Agreement and the license granted hereunder shall expire when the last patent licensed hereunder has expired. 2.8 Sublicense Rights. Licensee shall have the sole and ----------------- exclusive right to grant sublicenses to any party with respect to the rights conferred upon Licensee under this Agreement, provided, however, that any such sublicense shall be subject in all respects to all of the provisions contained in this Agreement (but not including the payment of patent costs pursuant to Sections 2.2 and 3.4 hereof and the obligation to pay minimum annual royalties pursuant to Section 2.3.3 hereof). Licensee shall pay Licensor, or cause its Affiliates or sublicensees to pay Licensor, the same royalties on all Net Sales of such Affiliate or sublicensee the same as if such Net Sales had been made by Licensee. Each Affiliate and sublicensee shall report its Net Sales to Licensor through Licensee, which Net Sales shall be aggregated with any Net Sales of Licensee for purposes of determining the Net Sales upon which royalties are to be paid to Licensor. Any royalties paid to Licensor with respect to Net Sales of any Affiliate or any sublicensee of Licensee or any Affiliate shall be credited against Licensee's minimum annual royalty obligations hereunder. 2.9 Duration of Royalty Obligations. The royalty obligations ------------------------------- of Licensee as to each Licensed Product shall terminate on a country-by-country basis concurrently with the expiration of the last to expire of the patents licensed hereunder utilized by or in such Licensed Product in each such country. Notwithstanding any other provision of this Agreement, in the event that, based upon a challenge by a party other than Licensee, its Affiliates or sublicensees, the existing favorable claims of the Licensed Patents are held to be invalid by the PTO or any competent court of law, Licensee may terminate this Agreement and Licensee thereafter shall have no further obligation to pay any royalties hereunder. 2.10 Reports. Licensee shall furnish to Licensor at the same ------- time as each royalty payment is made by Licensee, a written report of Net Sales of Licensed Products and the royalty due and payable thereon, including a description of any offsets or credits deducted therefrom, on a product-by- product and country-by-country basis, for the calendar quarter upon which such royalty payment is based. 2.11 Records. Licensee shall keep, and cause its Affiliates ------- and sublicensees to keep, complete records and accounts of all sales of Licensed Products in sufficient detail to enable the royalties payable on Net Sales of each Licensed Product to be determined. Licensor shall have the right to appoint an independent certified public accounting firm approved by Licensee, which approval shall not be unreasonably withheld, -7- <PAGE> to audit, upon delivery of advance written notice and during normal business hours without interruption of normal business operations, the records of Licensee, its Affiliates and sublicensees as necessary to verify the royalties payable pursuant to this Agreement. Licensee, its Affiliates and sublicensees shall pay to Licensor an amount equal to any additional royalties to which Licensor is entitled as disclosed by the audit. Such audit shall be at Licensor's expense. Licensor may exercise its right of audit hereunder no more frequently than once in any calendar year. The accounting firm shall disclose to Licensor only such information as is necessary to verify the accuracy of the royalty payments required hereunder, and all such information shall be treated as Confidential Information by Licensor. Licensee, its Affiliates and sublicensees shall preserve and maintain all records required for audit for a period of three (3) years after the calendar quarter to which the record applies. 2.12 Foreign Taxes. Any tax required to be withheld by ------------- Licensee under the laws of any foreign country for the account of Licensor shall be paid by Licensee for and on behalf of Licensor to the appropriate governmental authority and deducted from any royalties payable by Licensee hereunder. 3. Patent Matters. -------------- 3.1 Validity of Licensed Patents. The parties hereto ---------------------------- acknowledge that there may be an issue concerning the validity of some of the claims of the existing Licensed Patents. In order to resolve such issue, Licensee may, in the exercise of its sole discretion and at its sole expense, request a re-examination of the existing Licensed Patents by the PTO and the applicable foreign agencies. Each of the parties hereto shall exercise good faith and due diligence in their efforts to establish the validity of the existing Licensed Patents. 3.2 Patent Prosecution and Maintenance. From and after the ---------------------------------- date of this Agreement, the provisions of this Section 3.2 shall control the prosecution and maintenance of the Licensed Patents. Licensee shall direct and control (i) the maintenance of Patent '292 and the re-examination of Patent '292 described in Section 3.1 hereof; (ii) the preparation, filing and prosecution of all other domestic and foreign patent applications relating to Licensed Technology (including any interferences and foreign oppositions); and (iii) the maintenance of any patents issuing therefrom. Licensee shall select the patent attorney, and the fees and expenses incurred by Licensee with respect to services performed by such patent counsel and any filing or other fees shall be paid as set forth below in Section 3.4. Licensor shall assist Licensee and patent counsel retained by Licensee as necessary to accomplish the patent processes described hereunder. Licensor shall sign all documents which are reasonably necessary to enable Licensee to prosecute and maintain all patent matters. Licensee shall use good faith and due diligence in determining -8- <PAGE> which foreign countries, in addition to the U.S.A., in which to file for and maintain patent rights, depending on the commercial benefits Licensee can reasonably anticipate in each country. In as much as Licensee is paying the patent costs, the ultimate decision as to all of these patent prosecution and maintenance matters shall be made by Licensee. 3.3 Information to Licensor. Licensee shall keep Licensor ----------------------- informed with regard to the patent application, re-examination and maintenance processes. Licensee shall deliver to Licensor copies of all patent applications, amendments, related correspondence, and other related matters. 3.4 Patent Costs.

Licensee ---------------------------------------- shall have the right but not the obligation to prosecute any and all infringements of any patent licensed hereunder and to defend all charges of infringement arising as a result of the exercise by Licensee, its Affiliates or sublicensees of the rights granted hereunder. Licensee may enter into settlements, stipulated judgments or other arrangements respecting such infringement, at its own expense. Licensor shall permit any action to be brought in his name if required by law, and Licensee shall hold Licensor harmless from any costs, expenses of liability respecting all such infringements or charges of infringement, except such infringements as shall result from any breach of warranty made by Licensor herein. Licensor agrees to provide all necessary assistance of a technical nature which Licensee may require in any litigation arising with respect to the Licensed Technology. In the event Licensee elects not to prosecute any infringement, Licensee shall notify Licensor in writing promptly and Licensor shall have the right to prosecute such infringement on his own behalf. If Licensee elects to prosecute an infringement, then Licensor shall not be entitled to do so. 3.6.2 Allocation of Recovery. Any damages or other ---------------------- recovery from an infringement action undertaken by Licensee pursuant to Section 3.6.1 shall be retained by Licensee as its exclusive property; but any such recovery, net of -9- <PAGE> Licensee's costs of litigation, shall be treated as "Net Sales" and Licensee shall pay a royalty thereon pursuant to Section 2.3.1 above. If Licensee elects to not prosecute an infringement, and Licensor does prosecute said infringement, then Licensee shall retain any recovery received from said prosecution. 4. Obligations Related to Commercialization. ---------------------------------------- 4.1 Commercial Development Obligation. In order to --------------------------------- maintain Licensee's exclusive license rights granted hereunder in force, Licensee shall use reasonable efforts and due diligence to develop the Licensed Technology into commercially viable Licensed Products, as promptly as is reasonably and commercially feasible, and thereafter to produce and sell reasonable quantities of Licensed Products.

If Licensee has not, by July 1, 1998, --------- pursued reasonable efforts and due diligence to develop the Licensed Technology into commercially viable Licensed Products, such that there is a reasonable probability of Net Sales forthcoming, then Licensor may require Licensee to pay to Licensor a one-time payment of Fifty Thousand Dollars ($50,000) as a condition to retaining the exclusivity of the license granted hereunder in force. If said payment is so required and not paid, then Licensee's rights under this Agreement shall become non-exclusive and no minimum royalties shall thereafter be payable. If Licensor concludes that Licensee has failed to pursue said reasonable efforts and due diligence, then Licensor shall give written notice of said conclusion to Licensee, and Licensee shall have three months after receipt of said notice to cure the failure. If there is a dispute as to whether there is a failure or a cure, the dispute shall be resolved by arbitration pursuant to Section 10.2 below. 4.3 Governmental Approvals and Marketing of Licensed ------------------------------------------------ Products. Licensee shall be responsible for obtaining all necessary governmental -------- approvals for the development, production, distribution, sale and use of any Licensed Product, at Licensee's expense. Licensee shall have sole responsibility for any warning labels, packaging and instructions as to the use of Licensed Products and for the quality control for any Licensed Product. 4.4 Product Liability Indemnity. Licensee hereby agrees --------------------------- to indemnify, defend and hold harmless Licensor from and against any liability or expense arising from any product liability claim asserted by any party as to any Licensed Product made or sold by Licensee or its Affiliates and sublicensees, other than any claim which arises due to a breach by Licensor of any warranty made herein. -10- <PAGE> 5. Representations and Warranties. Licensor hereby represents and ------------------------------ warrants that (i) he is the rightful owner of the Licensed Technology, (ii) the Licensed Technology is not subject to any lien, license, assignment, security interest or other encumbrances, (iii) he has made full disclosure to Licensee of all communications with respect to the Licensed Technology with the PTO and any foreign patent agencies, (iv) he has the power and authority to enter into this Agreement and grant the license provided for hereunder, and (v) except as disclosed to Licensee, Licensor has no knowledge that the Licensed Technology infringes any patents or other intellectual property rights of third parties, or that any third party is in any way infringing the Licensed Technology covered by this Agreement. 6. Interests in Intellectual Property Rights. ----------------------------------------- 6.1 Preservation of Title. Licensor shall retain full --------------------- ownership and title to Licensed Technology, Patent '292 and any other patents licensed hereunder and shall use his reasonable best efforts to preserve and maintain such full ownership and title. 6.2 Ownership of Improvements. ------------------------- 6.2.1 Developed by Licensee.

The parties agree ------------------------------------- that during the term of this Agreement, and for a period of three (3) years after this Agreement terminates, a party receiving Confidential Information of the other party will (i) maintain in confidence such Confidential Information to the same extent such party maintains its own proprietary industrial information, (ii) not disclose such Confidential Information to any third party without prior written consent of the other party and (iii) not use such Confidential Information for any purpose except those permitted by this Agreement. 7.2 Publications. In order to protect the rights granted to ------------ Licensee hereunder, Licensor shall submit to Licensee copies of proposed publications of Licensor which contain subject matter relating to intellectual property licensed hereunder and -11- <PAGE> afford Licensee sixty (60) days to review such proposed publications. Upon timely written request by Licensee, Licensor shall delay any such publication to facilitate the preparation and filing of a patent application, which delay shall not exceed ninety (90) days from the date Licensee requests such delay. 8. Termination. ----------- 8.1 Termination Upon Default. Upon the failure of a party to ------------------------ perform any obligation required of it or him to be performed hereunder, and the failure to cure within thirty (30) days after receipt of written notice from the other party specifying in reasonable detail the nature of such default, the non- defaulting party may deliver to the defaulting party written notice of intent to terminate, such termination to be effective upon the date set forth in such notice. Such termination rights shall be in addition to and not in substitution for any other remedies that may be available to the non-defaulting party. Termination pursuant to this Section 8.1 shall not relieve the defaulting party from liability and damages to the other party for breach of this Agreement. Waiver by either party of a single default or a succession of defaults shall not deprive such party of any right to terminate this Agreement arising by reason of any subsequent default. 8.2 Transfer Upon Bankruptcy or Insolvency.

Except as otherwise provided in Section 8.5 of this Agreement with respect to work-in-progress, upon such termination, Licensee shall have no further right to develop, manufacture or sell any Licensed Products, or to otherwise use any Licensed Technology. Any such termination shall not relieve either party from any obligations accrued to the date of such termination. Upon such -12- <PAGE> termination, each party shall be required to abide by its nondisclosure obligations as described in Section 7.1, and, provided termination was not initiated by Licensee due to Licensor's breach hereunder, Licensee shall continue to abide by its obligations to indemnify Licensor as described in Section 4.4 for products sold prior to the termination. 8.5 Work-in-Progress. Upon any early termination of this ---------------- Agreement and the license granted hereunder, Licensee shall be entitled to finish any work-in-progress and to sell any completed inventory of Licensed Products which remain on hand as of the date of termination, so long as Licensee pays to Licensor the royalties applicable to such sales in accordance with the terms and conditions as set forth in this Agreement . 9.
