If Comcast cancels an Order prior to the Order Cancellation Deadline, Concurrent shall use commercially reasonable efforts to use the VOD Products specified in such Order to fulfill other Orders from Comcast or other customers; provided that to the extent that Concurrent cannot use the VOD Products specified in such Order to fulfill other Orders from Comcast or other customers within a reasonable time frame, Comcast shall, except as otherwise provided in Section 19.2 below, pay or reimburse Concurrent for all costs and expenses incurred by Concurrent in connection with such Equipment which are not recovered by Concurrent within such period.

Concurrent reserves the right to terminate any license of the Software upon written notice to Comcast in the event that (i) Comcast shall fail to pay any portion of the purchase price or license fee for the VOD Products when due, or (ii) Comcast shall make any improper use, transfer, duplication or disclosure of the Software or in any other way breach this Agreement, provided that Comcast shall have thirty (30) days from the date of such notice to cure such breach. If the breach is not cured within the applicable cure period and the license is terminated in accordance with this Section14.5, Comcast shall immediately return the applicable Software and related documentation and any copies thereof to Concurrent. Comcast's right to cure any breach in accordance with this Section 14.5 shall not affect Concurrent's right to obtain injunctive relief immediately upon the occurrence of any such breach. 15. WARRANTY/INFRINGEMENT INDEMNITY 15.1 Concurrent warrants that the Equipment shall be fully functional and free from defects in material and workmanship, and shall materially conform to the functional specifications set forth in Attachment A, for a period of **** from the Installation Date (the "Initial Warranty Period"). The foregoing warranty shall not apply unless the VOD Products are operated in accordance with Concurrent's manuals furnished with the VOD Products. Written notice of any claimed defect must be given within thirty (30) days after such defect is first discovered. Concurrent's obligation under such warranty is limited, at its option, to the repair or replacement of the Equipment or components or parts thereof which do not comply with such warranty. Such repair or replacement shall be made at Concurrent's designated plant or repair facility, and shall be at Concurrent's expense; provided, however, that all transportation and inspection charges covering any such returned Equipment or component or part that proves -5- not to be defective in accordance with the terms of such warranty shall be paid by Comcast. No Equipment shall be returned to Concurrent until Comcast receives written instructions regarding return procedures. The warranty in this Section 15.1 shall not extend to any labor charges for physical removal and/or replacement of defective Equipment or components or parts thereof. 15.2 Concurrent warrants that the Software furnished hereunder shall perform in material conformance with its published specifications for a period of **** from the Installation Date. In the event of any failure to so perform, Concurrent shall, at the request of Comcast, use reasonable commercial efforts to repair or circumvent any defect affecting such performance; provided that such reparation or circumvention shall be Comcast's sole remedy for any such failure of the Software to perform in accordance with the warranty in this Section15.2. It is understood that Concurrent does not warrant that the Software will be error-free. 15.3 Notwithstanding anything herein to the contrary, VOD Products that are not manufactured or developed by Concurrent, but are supplied or sublicensed by Concurrent, and which are wholly or partially integrated into a system are warranted only to the extent, and subject to the terms, of the original warranty given by the manufacturer of such VOD Products to Concurrent. Comcast shall give prompt written notice to Concurrent of any defect or failure of such VOD Products and provide proof thereof. 15.4 Comcast shall have the right at any time it places an Order to purchase a twelve (12) month extension to the warranty in Section 15.1 for the Equipment purchased in such Order at an additional cost equal to the product of (x) **** and (y) the purchase price set forth in the Order for such Equipment. 15.5 The warranties set forth in this Agreement shall not apply to VOD Products requiring adjustments, correction, repair or replacement, or increase in service time, caused by: (a) electrical work external to the VOD Products, or the attachment or use of accessories or other devices, including networking devices, not furnished, approved or recommended by Concurrent; or failure to properly maintain the same; (b) accident, transportation, neglect or misuse; (c) alterations, including, but not limited to, any deviation from circuit or network designs or structural equipment recommended by Concurrent, installation or removal of Product features not recommended by Concurrent, and all other modifications not recommended by Concurrent, which are performed by any person other than those authorized by Concurrent; (d) failure to provide and maintain a suitable installation environment with all facilities specified by Concurrent (including, but not limited to, failure of, or failure to provide, adequate electrical power, air-conditioning, humidity control) or from use of supplies or materials not meeting Concurrent's specifications; (e) repair or replacement of consumable supplies or parts which have reached the end of their useful life; or (f) the use of a Product for other than the purposes for which it is designed. 15.6 CONCURRENT MAKES NO REPRESENTATION OR WARRANTY OTHER THAN THOSE SET FORTH IN THIS AGREEMENT. THE WARRANTIES SET FORTH IN THIS AGREEMENT ARE EXPRESSLY MADE IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, ANY EXPRESS OR IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. -6- 15.7 Concurrent shall, at its expense, defend, indemnify and hold harmless Comcast from and against any claim of infringement of any United States patents or copyrights by any VOD Products manufactured or developed by Concurrent, provided that (i) Concurrent is promptly informed in writing of such claim and furnished a copy of each communication, notice or other action relating to the alleged infringement, (ii) Concurrent shall have control over the defense and negotiations for a settlement or compromise, (iii) Concurrent is given all reasonable authority, information and assistance from Comcast necessary to defend or settle such suit or proceeding (at Concurrent's expense), and (iv) Comcast incurs no obligation or liability without the prior written consent of Concurrent. The foregoing obligation of Concurrent does not apply to VOD Products or portions or components thereof (a) which are modified by persons or entities other than Concurrent (or persons or entities employed or contracted by Concurrent) if the alleged infringement relates to such modification unless such modification was recommended or approved by Concurrent or (b) combined with other products, processes or materials not supplied or recommended by Concurrent where the alleged infringement relates to such combination. If any claim that Concurrent is obligated to defend has occurred or, in Concurrent's opinion, is likely to occur, Concurrent may, at its option, either (i) procure for Comcast the right to continue to use the applicable VOD Product or (ii) replace or modify the VOD Product so it becomes non-infringing. 16. LIMITATION OF LIABILITY Except for Concurrent's obligations under Section 15.7 above, and except for personal injury or tangible property damage caused by the gross negligence or willful misconduct of Concurrent in the performance of services hereunder, Concurrent's liability in contract, tort or otherwise arising out of or in connection with the performance of any Product, shall not exceed the purchase price or license fee paid by Comcast with respect to such Product that is the subject of the claim. IN NO EVENT SHALL CONCURRENT OR ITS DEVELOPERS OR AFFILIATES OR THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, AGENTS OR REPRESENTATIVES BE LIABLE FOR SPECIAL, INDIRECT, EXEMPLARY, INCIDENTAL, MULTIPLE, CONSEQUENTIAL, OR TORT DAMAGES (INCLUDING ANY DAMAGES RESULTING FROM LOSS OF USE, LOSS OF DATA, LOSS OF PROFITS, LOSS OF SAVINGS, LOSS OF BUSINESS OR OTHER ECONOMIC LOSS) ARISING OUT OF OR IN CONNECTION WITH THE PERFORMANCE OF ANY PRODUCT, COMCAST'S INABILITY TO USE SUCH PRODUCT OR CONCURRENT'S PERFORMANCE OF SERVICES HEREUNDER, EVEN IF CONCURRENT HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17.

CONFIDENTIALITY 18.1 It is anticipated that each party may be required to exchange certain confidential information ("Information") to the other in the course of performing this Agreement. From the date of disclosure, and until **** years following such date, the recipient of Information ("Recipient") shall maintain the Information in confidence and use the Information solely to perform its obligations or enforce its rights under this Agreement, using at least the same degree of care as it employs to protect its own confidential information of a similar nature, but not less than a reasonable standard of care, provided that the Information is identified in writing as confidential at the time of disclosure, or if orally disclosed, is identified as confidential at the time of disclosure and confirmed in writing within twenty (20) days after such oral disclosure. Recipient shall have no obligation hereunder with respect to any Information that is: (a) generally known to the public at the time of disclosure, or becomes known to the public without breach of this Agreement; (b) known to the Recipient prior to the disclosure, or is independently developed by the Recipient without reference to or use of any other portion of the Information; (c) obtained by the Recipient in good faith from a third party not under obligation of secrecy to the disclosing party (hereafter referred to as "Disclosing Party"); or (d) the subject of a court or government agency order to disclose, provided that the Recipient gives prompt written notice to the Disclosing Party to allow the Disclosing Party to contest such order. The Recipient shall have the burden of proving that any of the above exceptions apply by means of documentary evidence available at the time Recipient claims the exception first became applicable. 18.2 Title to all tangible forms of the Information, and all copies thereof, shall be and remain with Disclosing Party. Recipient shall not copy or otherwise reproduce, in whole or in part, any Information without the prior written authorization of Disclosing Party, except as may be reasonably necessary to fulfill the purpose of this Agreement. Recipient shall not disclose any Information to any third party other than its officers, directors, employees, agents and representatives having a need to know such Information to support performance of this Agreement, provided that each such party given access to any such Information is subject to a written confidentiality agreement whose terms are substantially similar to this Section 18.2. Recipient shall promptly return or destroy all tangible forms of the Information, and copies thereof, upon Disclosing Party's request or termination of this Agreement, and if such Information is destroyed, shall promptly provide evidence reasonably satisfactory to the Disclosing Party of such destruction. 18.3 It is understood, however, that Concurrent has performed substantial development relating to the design and manufacture of digital video and other products, and that Concurrent has relationships with other companies which may be competitors of Comcast. It is further understood that Comcast has relationships with other companies that may be competitors of Concurrent. Neither this Agreement, nor receipt of Information hereunder, shall limit either party's independent development, manufacture or marketing of products or systems involving technology or ideas similar to the VOD Products or other products or systems disclosed in any Information or otherwise, nor will this Agreement or receipt of Information hereunder prevent either party from entering into discussions or agreements for the purchase or licensing of products or systems similar to the VOD Products with third parties, including competitors of the other party. -8- 19. TERM AND TERMINATION 19.1 This Agreement will become effective as of the date first above written and, unless earlier terminated in accordance with this Agreement, will continue, unless extended pursuant to the following sentences, until March 31, 2004. At the sole option of Comcast, this Agreement may be extended for one (1) term of **** years (the "Optional Extension"), by giving notice of extension to Concurrent at least thirty (30) days prior to March 31, 2004. If Comcast exercises its right to the Optional Extension, the terms and conditions of this Agreement shall be extended for **** years, and thereafter will automatically renew, on each anniversary of March 31, for successive one-year periods (each such period, an "Evergreen Year"), unless either party gives written notice of termination at least ninety (90) days prior to the beginning of a new Evergreen Year. 19.2 If Concurrent does not complete the actions listed in subparagraphs (a), (b) and (c) of Section 5.1 on or before September 30, 2001, Comcast shall have the right, in its sole discretion, which may be exercised by written notice to Concurrent at any time before the earlier of the close of business on December 31, 2001 or the Completion Date, to terminate this Agreement, or if Comcast does not so terminate this Agreement and Concurrent does not complete the actions listed in subparagraphs (a), (b) and (c) of Section 5.1 on or before December 31, 2001, this Agreement shall automatically terminate (unless termination is waived by Comcast) without any further action by either party hereto, on December 31, 2001. 19.3 Either party shall be in default of this Agreement if such party: a) fails to make any payment required to be made hereunder when such payment is due and such failure continues for fifteen (15) business days after receipt of written notice of such failure; b) fails to perform any of its material obligations under this Agreement (other than a payment obligation) and such failure continues for thirty (30) calendar days after receipt of written notice of such failure, or if such failure cannot be cured within such thirty (30) day period, but the defaulting party diligently pursues a cure of such default during such thirty (30) day period and thereafter, such failure continues for sixty (60) calendar days after receipt of written notice of such failure; c) assigns this Agreement, or any obligation or right under this Agreement, to a third party that is not an Affiliate of such party; or d) becomes insolvent or makes an assignment for the benefit of creditors, or a receiver or similar officer is appointed to take charge of all or part of that party's assets. In the event of a default, the non-defaulting party may terminate the Agreement and any outstanding Orders by written notice to the defaulting party. 19.4 Termination or expiration of this Agreement shall not relieve either party of any of its then-accrued obligations, including without limitation the obligation to pay for delivered VOD Products or for any then-applicable cancellation charges pursuant to this Agreement. For avoidance of doubt, Comcast shall have no obligations under the deployment commitment in Section 4.1 after termination or expiration of this Agreement. -9- 20. MOST FAVORED CUSTOMER PROVISION 20.1 (a) Subject to Sections 20.1(b) and 20.1(c) hereof, each of Comcast and its Affiliates is hereby accorded the right to receive "most favored customer" terms and conditions from Concurrent and any of its Affiliates with respect to the purchase or licensing of VOD Products and the purchasing of services. (b) The "most favored customer" status afforded Comcast and its Affiliates hereunder shall be applied with respect to the economic terms (including, without limitation, pricing and any and all kinds of incentives, including, discounts and warrants and related terms) of a transaction by comparison of the complete economic offering of the VOD Products and services offered to Comcast or any of its Affiliates on the one hand and a third party on the other (regardless of the size or identity of such third party or their ownership interests in Concurrent or any of its Affiliates). If Concurrent or any of its Affiliates on the one hand and a third party on the other hand enter into a contract which causes the economic effect of the overall contractual relationship between Comcast or any of its Affiliates and Concurrent or any of its Affiliates to be less favorable than the economic effect of Concurrent's or its Affiliates' contractual relationship with such third party, taken in its entirety, then each of Comcast and its Affiliates shall have the right to have its economic terms with respect to the VOD Products and services, taken in its entirety, amended such that the economic effect of the overall contractual relationship between Comcast or any of its Affiliates and Concurrent or any of its Affiliates shall be on no less favorable terms, taken in its entirety, than Concurrent's or its Affiliates' contractual relationship with such third party, taken in its entirety. For purposes of comparing the economic terms of a transaction, the size of the transaction (through volume discounts or otherwise) may be considered, and Comcast and its Affiliates must be offered economic terms no less favorable than other customers of Concurrent or any of its Affiliates that purchase a similar or lesser quantity of goods or services. (c) Subject to subparagraph (d) below, the "most favored customer" status afforded Comcast and its Affiliates hereunder shall be applied with respect to the non-economic terms of a transaction by comparison (by Comcast) of the complete offering of the VOD Products and services to Comcast or any of its Affiliates on the one hand and a third party on the other (regardless of the size or identity of such third party or their ownership interests in Concurrent or any of its Affiliates). If, in Comcast's sole judgment, Concurrent or any of its Affiliates on the one hand and a third party on the other hand enter into a contract whereby the economic and non-economic terms (taken as a whole) are more favorable than the economic and non-economic terms (taken as a whole) in a contract between Concurrent or any of its Affiliates on the one hand and Comcast or any of its Affiliates on the other hand, then each of Comcast and its Affiliates shall have the right to substitute its complete offering of economic and non-economic terms (taken as a whole) with respect to such VOD Products and services, with such third party's complete offering of economic and non-economic terms with respect to the VOD Products and services (taken as a whole). For purposes of comparing the non-economic terms of a transaction, the size of the transaction (through volume discounts or otherwise) may not be considered. (d) In the event that Concurrent or any if its Affiliates enters into any agreement with any other person or entity (regardless of the size or identity of such person or entity or their ownership interests in Concurrent or any of its Affiliates) relating to Concurrent's VOD Products or VOD-related products and services, which agreement contains a "most favored customer" provision that is superior to the provisions of this Section 20, Comcast and all of its Affiliates shall be entitled to the benefit of such superior "most favored customer" provision, regardless of any other term of the contract in which the superior "most favored customer" provision appears. (e) The "most favored customer" terms and conditions contained in this Section 20 shall not apply to (a) any existing customer agreements that were disclosed to Comcast prior to the Closing Date in a written document referring specifically to this Section 20 or (b) any special promotional pricing arrangements offered to potential customers (which shall not include existing customers unless such special promotion relates to existing goods, products or equipment and simultaneously with any offer to any such existing customer Concurrent offers the same special promotional pricing arrangements to Comcast with respect to such goods, products and equipment), provided that such arrangements do not exceed three months in duration. Special offers made available to any current customers with respect to new goods, products, equipment or services shall be subject to the "most favored customer" provisions set forth herein. 20.2 Comcast may, upon reasonable notice to Concurrent, instruct an external independent auditor reasonably satisfactory to Concurrent to audit the relevant books and records of Concurrent to ensure compliance with Section 20.1; provided that such audit shall not be conducted more frequently than annually and shall be conducted at a place and time during normal business hours reasonably acceptable to Concurrent and shall be conducted in such a manner as not to unreasonably interfere with the normal business operations of Concurrent; and provided further that Comcast and its independent auditors shall enter into confidentiality agreements reasonably satisfactory to Concurrent with respect to the review in such audit of information relating to Concurrent's contractual relationship with any third party. In the event that Concurrent violates the provisions of Section 20.1 in any material respect, Concurrent agrees to (i) pay the reasonable expenses of the independent auditor, (ii) adjust the terms and conditions of this Agreement to give retroactive and prospective effect to the non-economic terms of the superior agreement, in accordance with the requirements of this Agreement, (iii) refund overpaid amounts to Comcast or its Affiliate, as the case may be, or apply a credit in the amount of the overpaid amounts against future license fees (at the election of Comcast or the Affiliate) and (iv) immediately grant to Comcast the improved terms or other benefits to which Comcast is entitled. 20.3 For the purposes of this Agreement the term "Affiliate" shall mean an "affiliate," as such term is defined under Rule 405 promulgated under the Securities Act of 1933, as amended (the "Securities Act"). 21. WARRANTS Simultaneously with the execution of this Agreement, and without any additional consideration therefor, Concurrent and Comcast shall enter into that certain Warrant Issuance Agreement (the "WIA"), of even date herewith, pursuant to which Concurrent shall issue to Comcast Concurrent Holding, Inc. (the "Holder") certain warrants, upon the terms and subject to the conditions set forth in such Warrant Issuance Agreement. 22. PUBLIC ANNOUNCEMENT Concurrent and Comcast shall agree on the form and content of any public announcement that shall be made concerning this Agreement and the transactions contemplated hereby, and neither Concurrent nor Comcast shall make any such public announcement without the prior written consent of the other, except as required by law. 23. GENERAL 23.1 Force Majeure. Neither party shall be liable for delays in performance ------------- of its obligations hereunder (other than payment obligations) arising out of or resulting from causes beyond such party's control. Such causes include, but are not restricted to, acts of God, any government authority, or the public enemy, fires, floods, epidemics, quarantine restrictions, strike, freight embargoes, shortages of materials, unusually severe weather, and default or delay of suppliers.

The customer can realize a substantial savings in travel costs. Instead of a customer having to pay for multiple students' travel expenses to Concurrent, they need only cover the instructor's cost of travel and expenses to their site. Even greater savings are realized for larger classes. Besides the differences in travel costs, savings are also realized in tuition costs when the maximum class size is utilized. In addition to these reductions in cost, there are several intangible benefits from choosing on-site courses: Employees will be trained on the Concurrent VOD Products for which they will be responsible. Multiple employees will not be absent from the customer's facility simultaneously. Optimum scheduling can be achieved based on customer requirements. On-site instruction includes one set of training materials, which may be reproduced by the customer for the number of students enrolled in the class. Should the implementation of a Video-On-Demand system require training which is not one of the regularly scheduled courses as listed in the published schedule, a customized course can be prepared and taught at the Training Center or on-site. This customized course can take the form of modifying the format of an existing course or developing a completely new course. 7 ATTACHMENT B The pricing specified in this Agreement includes all reasonable parameters required to correctly design, install, operate and maintain a fully functional, highly reliable commercial Concurrent VOD system including, but not limited to, media asset loading and management, video storage/pump, DVB/ASI and QAM output, server interconnect equipment/Ethernet hubs, and all software.
