The parties further intend that this Agreement describe a process by which the parties not only will develop the Initial Products, but also may add products to the Product Line from time to time as "Additional Products" hereunder and otherwise conduct other development projects from time to time as "Additional Projects" hereunder, pursuant to the terms of Section 2.2 below. 2.1.4. Ability to Modify. In order to develop a basis for entering into this Agreement, the parties have prepared and agreed upon an initial Statement of Work, described in the Binder, under the heading "Statement of Work for the * Project" setting forth a description applicable to the Initial Development Project. The initial Statement of Work will operate as a base line for the Initial Development Project. The parties recognize that additional clarification and refinement of the Statement of Work will be required for the Initial Development Project, 6 7 *CONFIDENTIAL* TREATMENT REQUESTED and that any initial Statement of Work for Additional Projects undertaken for the development of Additional Products will similarly require clarification and refinement. Therefore the parties intend that this Agreement establish a process by which the parties may amend the Statement(s) of Work, thereby amending the nature and scope of the Project(s), pursuant to the terms of Section 2.3. 2.2. ADDITIONAL PROJECTS. 2.2.1. Request for Additional Product or Other Development Work. From time to time during the term hereof, either party (i) shall, prior to commencing development alone or with a third party of (x) any new product or product line within the * Field which uses Jointly Developed Technology, (y) development of any enhancements or modifications or improvements to existing Products, or (z) licensing any technology to a third party to permit either of the foregoing within the * Field, suggest, and (ii) may, in any other instance, suggest the addition of additional products in the Product Line or the conduct of additional joint development work pursuant to the terms of this Agreement. Either party shall make such request by submitting to the other an Additional Product Appendix, in the form attached to this Agreement as Exhibit 2.2.1. Promptly upon receipt of such form, the receiving party shall provide the submitting party with an oral indication of interest in proceeding with the additional development project. 2.2.2. Preparation of Statement of Work. In the event that the receiving party indicates a willingness to proceed, then the parties shall meet and determine which party should conduct the development of such Additional Project hereunder. Promptly upon such determination, the party selected to conduct the development (the "development party") shall complete and return to the other party a detailed Product Marketing Specification, System Design Specification, Development Schedule, Resource Plan and Expense Analysis applicable to the Additional Product or Products or additional development Project requested. Costs incurred by the developing party in preparing such response to the request shall be included in Development Costs. To the extent that a requested Additional Product or Products have interdependencies with the rest of the Product Line then under development, the developing party shall, concurrently with the preparation and submission to the other of the response to request, propose corresponding changes to the Product Marketing Specification, System Design Specifications, Development Schedule, Resource Plan and Expense Analysis for the Product or Products then under development affected by such requested Additional Project. Neither party assumes any obligation to pay for development work performed on Additional Project until such Additional Project shall have been approved in accordance with the provisions of Section 3.3. When the Statement of Work applicable to the proposed Additional Project(s) shall have been approved under Section 3.3 then such project shall constitute an "Additional Project" hereunder and any products described therein shall constitute "Additional Products" hereunder, a new Additional Project Binder will be created in which all documents related to such Additional Project shall be prepared and maintained by ADA. 2.2.3. * Products. The parties agree that it is their intention to develop versions of the Products which are * compliant in accordance with the Additional Products process described herein, if sufficient demand for such Products is determined to exist. Accordingly, the 7 8 *CONFIDENTIAL* TREATMENT REQUESTED parties agree to commence market research to determine if there is sufficient demand and each party shall bear the costs of its market research regarding any * product. Upon the completion of such market research either party may request that an * product be an Additional Product as set forth in Sections 2.2.1 and 2.2.2. The request shall also include an analysis of work required and preparation of cost estimates with respect to an * version of the Products. It is the intent of the parties that such a request will be submitted by one party to the other within 90 days of the execution of this Agreement. 2.3. DESIGN CHANGES AFTER COMPLETION DATE. 2.3.1. Statement of Intention . The parties agree that, during the term hereof, they will each exercise best efforts to maintain a single product design for the Product Line, and for each Product therein. The parties acknowledge and agree that a single product design enjoys economies of scale, including without limitation, economies in the manufacture and engineering and technical support of the Product Line, and further that a single product design enhances the ability to optimize joint marketing and sales efforts. Therefore, it is the parties' intention and agreement that the Product Marketing Specification and the System Design Specification represent the single product design which the parties will attempt to maintain. 2.3.2. Changes to Product Line or Products. Notwithstanding the foregoing, the parties recognize that from time to time during the term hereof some one or more customers may desire, or anticipated customer desires may dictate, that special enhancements or modifications be made to the Product Line, or to any Product therein or to add certain properties or products thereto, and that either party may desire to adopt such changes requested by the customer or anticipated to be desired by customers. From and after the Completion Date with respect to any particular Product, each party will notify the other promptly upon receipt of a request from a customer, or upon identification of an anticipated customer need, to implement any enhancement, modification or other change to the Product Line, or any Product therein. The receiving party shall have not more than ten (10) business days within which to request that such enhancement be a joint development between the parties, and the subject of an Additional Project under the terms of this Agreement and Section 2.2 above. In the event the receiving party elects not to participate, or fails to respond within such ten (10) business day period, then the requesting party shall have the right to conduct such product development alone, at its sole cost and expense, subject to the terms of this Agreement and the Technology License Agreement. The requesting party shall not be required to license to the responding party any intellectual property, other than Improvements made to technology in the other party's Field which cannot be practiced without using or infringing on the other party's Technology, arising from such independent product development conducted during the term hereof.
