WHEREAS, although SpecTran and Corning are both manufacturers of multimode optical fiber, Corning in 1996, 1997 and 1998 will not have sufficient capacity to manufacture needed quantities of such optical fiber, and SpecTran is willing to sell limited quantities of such fiber to Corning as provided in this Contract; and WHEREAS, the parties will administer this Contract in a manner so that there will be no discussions between them of general optical fiber pricing, of specific optical fiber pricing that either is offering or has offered to third parties or of proprietary aspects of optical fiber market developments; and WHEREAS, both parties agree that there is no understanding between them regarding optical fiber supply from SpecTran to Corning other than for the three years of this Contract, and only for specific amounts stated herein; and WHEREAS, prior to the date of this contract the parties have acted as normal arm's length competitors in the marketplace; and WHEREAS, during the term of this Contract the parties will continue to act as normal arm's length competitors in the marketplace; 4 * CONFIDENTIAL TREATMENT GRANTED -2- THEREFORE, the parties hereto agree as follows: ARTICLE 1 --------- Sales and Purchases of Multimode Optical Fiber ---------------------------------------------- 1.1 Multimode Fiber Purchase Amounts. -------------------------------- SpecTran hereby commits to sell to Corning and Corning commits to purchase from SpecTran during 1996 *** kilometers of multimode optical fiber. For 1997, (i) SpecTran shall have available to sell to Corning *** kilometers of multimode optical fiber, and (ii) Corning commits to purchase from SpecTran an amount at Corning's sole option which is *** of multimode optical fiber. For 1998, (i) SpecTran shall have available to sell to Corning *** kilometers of multimode optical fiber, and (ii) Corning commits to purchase from SpecTran an amount at Corning's sole option which is between *** of multimode optical fiber. By way of clarification, from the preceding two sentences, Corning's only commitment, as of the date of this Contract, to purchase multimode optical fiber from SpecTran for 1997 is *** and for 1998 is ***. Without regard to the preceding paragraph of this Section 1.1 as it relates to projected 1998 multimode optical fiber quantities, prior to the end of 1996 Corning and SpecTran will either reconfirm or change the quantities stated in such paragraph for 1998, at which time such reconfirmed or changed 1998 quantities will be quantities which SpecTran will have available to sell and Corning will commit to purchase for 1998; the exact amounts to be purchased and 5 * CONFIDENTIAL TREATMENT GRANTED -3- sold for 1998 will be as specified quarterly as per the following paragraph. Not later than the last day of each calendar quarter in 1996, Corning and SpecTran shall agree to the number of multimode fiber kilometers which shall be SpecTran's committed supply and Corning's committed purchase for the corresponding quarter in 1997. When the 1997 fourth quarter amount is agreed to, the total agreed upon kilometers of multimode optical fiber for 1997 shall be between *** . On a quarterly basis in 1997 the parties shall follow the same procedure for 1998 actual quarterly committed SpecTran supply and committed Corning purchase that they followed for 1997, as described in the first sentence of this paragraph. When the 1998 fourth quarter amount is agreed to, the total agreed upon kilometers of multimode optical fiber for 1998 shall be between *** and *** , unless such range is changed by mutual agreement of the parties on the basis of the preceding paragraph. All optical fiber purchased hereunder by Corning may be resold by Corning to any third party or parties of Corning's selection. Optical fiber made for and sold to Corning hereunder shall not be subject to and shall be outside of the terms of the license agreement effective as of the first day of January 1991 by and between Corning and SpecTran. If during 1996, 1997 or 1998, in addition to the above minimum SpecTran supply commitment for that year, Corning at its sole option wants to purchase any amounts of multimode optical fiber which would exceed the total agreed upon number of kilometers for such year (as stipulated in the second and third paragraphs of this Section 1.1), then not 6 * CONFIDENTIAL TREATMENT GRANTED -4- less than thirty (30) days prior to its needed delivery of such additional fiber Corning shall submit its request therefore in writing to SpecTran. Within fifteen (15) days after receiving such request, SpecTran shall reply in writing, indicating which portion (or none or all) of such additional fiber which SpecTran will also commit to supply to Corning during such year. Any portion which SpecTran by such return letter agrees to supply, SpecTran shall sell to Corning at the per meter price referenced in Section 1.2. Without regard to the preceding provisions of this Section 1.1 or any other provisions of this Contract (unless the parties have mutually agreed to purchase and sell more than *** in accordance with the procedures provided above), at the point that Corning purchases *** of multimode optical fiber from SpecTran during the term hereof, then all of Corning's obligations to purchase multimode optical fiber hereunder shall cease, even if these *** are purchased before the end of the three year term hereof. Similarly, in such an event, SpecTran's corresponding obligation to keep multimode optical fiber available for Corning's possible purchases hereunder shall also cease. 1.2 Per Meter Pricing. ---------------- The FOB SpecTran factory per meter invoice prices to Corning for all types of multimode fiber for 1996, 1997 and 1998 will be as shown in Attachment B. 1.3 Shipments. --------- The estimated 1996 monthly shipment schedule for multimode optical fiber supplied hereunder is listed on Attachment A 7 - 5 - hereto. The 1997 schedule shall be agreed to prior to November 1, 1996 and the 1998 schedule prior to November 1, 1997. Shipments are made on an FOB basis SpecTran's plant. SpecTran, at Corning's option, will either ship optical fiber to Corning or will drop ship it to a cable customer of Corning. 1.4 Technical Specifications and Product Mix. ----------------------------------------- The specifications for multimode optical fiber and the different types of optical fiber sold hereunder are included in Attachment B. 1.5 Payment Terms. -------------- All optical fiber sold hereunder shall be on the basis of payment due from Corning within forty five (45) days after SpecTran's FOB factory shipment. Interest at the rate of the current Citibank N.A., New York prime rate per month will be charged on all accounts at least ten (10) days past due, unless a lower rate is required by law. 1.6 Nonexclusive Supply. -------------------- By way of clarification, nothing in this Contract precludes Corning from sourcing optical fiber from any party other than SpecTran or from SpecTran selling optical fiber to any party other than Corning. 1.7 Claims for Missing or Damaged Optical Fiber. -------------------------------------------- If for reasons attributable to SpecTran, there is physical damage to or shortage in optical fiber supplied hereunder, 8 * CONFIDENTIAL TREATMENT GRANTED - 6 - resulting in any way from SpecTran's handling of such fiber after it was produced by SpecTran, a return authorization shall be made and signed by the parties. The determination under the preceding sentence must be made no later than one hundred twenty days after SpecTran's FOB shipment of the fiber with the missing or damaged portion. This signed return authorization shall serve as the basis for any claim by Corning against SpecTran, for SpecTran to give Corning appropriate credit for such damaged or missing optical fiber or to replace such fiber, at Corning's option, which credit or replacement shall be Corning's sole and exclusive remedy under this Section 1.7. 1.8 *** A. For SpecTran. ------------ If during any year hereof *** ------------------------- 9 * CONFIDENTIAL TREATMENT GRANTED B. For Corning. ----------- If during any year hereof *** 10 * CONFIDENTIAL TREATMENT GRANTED - 8 - ARTICLE 2 --------- Limited Warranty ---------------- 2.1 Warranty. --------- (a) SpecTran warrants that at the time of its shipment of multimode optical fiber supplied hereunder will conform to the written specifications identified in Attachment B and shall be free from defects of design and/or workmanship and shall be fit for its intended purposes (as per item 1.2 "Product Application" in Attachment B "Purchase Specification").
