2. “Licensor” is Terathon Software LLC, a California limited liability company.
3. “Licensee” is an individual or company who becomes a party to this agreement and consequently gains access to source code and other materials composing the C4 Engine.
4. “Work” is a product or any part of a product created by a Licensee using the C4 Engine, any component of the C4 Engine, or any modified version of the C4 Engine.

II. LICENSE
1. This agreement grants a single Licensee a limited, non-exclusive license to use the C4 Engine for the purposes of creating software products including, but not limited to, games, simulations, and scientific applications. A separate license must be purchased for each individual who is to have access to the C4 Engine.
2. Any potential Licensee, whether it be an individual or a business entity, who has directly or indirectly entered into a publishing agreement with a Publisher is not eligible to enter into the C4 Engine Standard License Agreement. If a Licensee becomes ineligible because a publishing agreement was entered after the Licensee entered the C4 Engine Standard License Agreement, then either (a) the Licensee must upgrade to the C4 Engine Professional License, or (b) this agreement must be terminated, upon which the Licensee is required to destroy all copies of the C4 Engine in its possession.
3. The Licensor agrees to provide to the Licensee all of the relevant materials, including source code, object code, tools, and documentation, that collectively make up the versions of the C4 Engine that function under the Microsoft Windows operating system and Apple Mac OS X operating system. Such materials shall be provided by means of electronic download.
4. The Licensor agrees to make available for download to the Licensee, at intervals determined solely by the Licensor, all revisions it makes to the C4 Engine.
5. The Licensee may create an unlimited number of Works using the C4 Engine.
6. Any Works created by the Licensee may be publicly or privately sold for a value less than $100.00 (US), distributed, or released by physical or electronic means so long as they do not include any source code or documentation belonging to the C4 Engine or any modification thereof. No Work may be sold at a value equivalent to $100.00 (US) or greater. The Licensee must upgrade to the C4 Engine Serious Games License in order to sell a Work for $100.00 or more.
7. This license may not be transferred to a third party under any circumstances.
III. FEES AND REQUIREMENTS
1. The Licensee agrees to pay to the Licensor a one-time, non-refundable fee of $350.00 (US) less any applicable discount. Payment of this fee allows a single individual to use the C4 Engine and to access the associated source code. A separate license must be obtained for each individual who is to have access to the C4 Engine source code.
2. For each Work created by the Licensee using the C4 Engine and distributed by any means, the “Powered by the C4 Engine” logo provided by the Licensor must be displayed as follows.
(a) If the Work has a title screen, then the logo must appear on the title screen. Alternatively, the Work may display the logo by itself for not less than one second before the title screen appears each time the Work is launched. In either case, the logo must be displayed at a reasonable size not less than 256 pixels in width.
(b) If the Work is distributed in a physical package, then the logo must be printed on the package at a size not less than one inch (2.54 cm) in width.
(c) In no case shall the logo be cropped or modified in appearance from its original form.
3. The Licensee may not sell, rent, lease, sublicense, or redistribute the C4 Engine or any augmentation or modification thereof to a third party, except as part of a Work, and then only in object code form. Under no circumstances may the Licensee distribute C4 Engine source code to a third party.
4. The Licensee shall not remove or alter any notice of copyright, trademark, patent, or confidentiality from the C4 Engine.
IV. NON-DISCLOSURE

The Licensee may not, through any means, disclose to any third party, excepting those who have also entered into this licensing agreement, any confidential information without the express written permission of the Licensor.
2. The Licensee acknowledges that the unauthorized disclosure of confidential information, whether intentional or accidental, may result in significant and irreparable damages to the Licensor, and that it may be difficult to assign a monetary value to such damages. Therefore, in the event of a breach of this section, the Licensor shall be entitled, without waiving any other rights or remedies, to such injunction or equitable relief as may be deemed proper by a court of competent jurisdiction.
3. The Licensee shall not be liable for disclosure of confidential information that (a) was publicly available at the time it was communicated to the Licensee, (b) was made publicly available by the Licensor at some time before disclosure by the Licensee, or (c) is required to be disclosed in response to a valid order by a court or other governmental body, provided that the Licensee provides the Licensor with at least ten (10) days prior written notice of such disclosure in order to permit the Licensor to seek confidential treatment of such information.
V. TERMINATION
The Licensor may, without waiving any rights, terminate this agreement if (a) the Licensee breaches any of its terms and conditions, (b) it is discovered that the Licensee misrepresented its identity or intentions, or (c) the Licensee attempts to circumvent or undermine any security mechanisms implemented on the Terathon Software website (www.terathon.com).
