You may engage in appropriate civic or charitable activities and devote a reasonable amount of time to private investments or boards or other activities provided that such activities do not interfere or conflict with your responsibilities and are not or are not likely to be contrary to Blackboard’s interests. You and Blackboard agree that your position is essential to Blackboard’s success and that the highest level of performance is required from you.

2. Term of Employment.

This Agreement shall automatically renew for successive one (1) year periods (each, a “Renewal Term” and together with the Initial Term, the “Term”) unless either party provides prior written notice of its intent not to renew within thirty (30) days of the applicable Renewal Term.

3. Compensation.

(a) Base Compensation. Your annual base compensation shall initially be US$350,000 (“Base Compensation”), less applicable taxes and withholdings, payable in accordance with Blackboard’s regular payroll practices from time to time in effect.

If you are uncertain whether something is Confidential Information you should treat it as Confidential Information until you receive clarification from Blackboard that it is not Confidential Information. Confidential Information shall remain at all times the property of Blackboard. You may use or disclose Confidential Information only as authorized and necessary in performing your responsibilities under this Agreement during your employment with Blackboard; with the General Counsel’s prior written consent; in a legal proceeding between you and Blackboard to establish the rights of either party under this Agreement, provided that you stipulate to a protective order to prevent any unnecessary use or disclosure; or subject to a compulsory legal process that requires disclosure of such information, provided that you have complied with the following procedures to ensure that Blackboard has an adequate opportunity to protect its legal interests in preventing disclosure. Upon receipt of a subpoena that could possibly require disclosure of Confidential Information, you shall provide a copy of the compulsory process and complete information regarding the circumstances under which you received it to Blackboard by hand delivery within twenty-four (24) hours. You will not make any disclosure until the latest possible date for making such disclosure in accordance with the compulsory process (“Latest Possible Date”). If Blackboard seeks to prevent disclosure in accordance with the applicable legal procedures, and provides you with notice before the Latest Possible Date that it has initiated such procedures, you will not make disclosures of any Confidential Information that is the subject of such procedures, until such objections are withdrawn or ruled on. You hereby acknowledge that any breach of this Section 8(a) would cause Blackboard irreparable harm.

(b) Outside Activities. You shall submit to Blackboard’s General Counsel, within a reasonable time prior to dissemination, the text of any speech, professional paper, article or similar communication created by you which relates to Blackboard’s present or future business or research and development endeavors. The General Counsel then will notify you if the dissemination of the communication is permitted under the terms of this Agreement.

(c) Ownership of Confidential Information; Return of Materials. All Confidential Information, including without limitation that which is produced by or for Blackboard by you or anyone else, all materials embodying Confidential Information, and all copies thereof, will remain the property of Blackboard or of the third party who has furnished it to Blackboard. On your Termination Date, or at the written request of Blackboard at any time, you will immediately deliver to Blackboard all materials, and copies thereof, which are in your possession or control and which contain or are related in any way to any Confidential Information. This includes all documents and other information prepared by you or on your behalf or provided to you in connection with your duties while employed by Blackboard, regardless of the form in which such document or information are maintained or stored, including computer, typed, written, imaged, audio, video, micro-fiche, electronic or any other means of recording or storing documents or other information. You hereby warrant that you will not retain in any form any such document or other information or copies thereof. You may retain a copy of this Agreement and any other document or information describing any rights you may have after the termination of your employment.

In the event that Blackboard is unable for any reason whatsoever to secure your signature to any lawful and necessary documents required to apply for or execute any patent application with respect to such idea, process, development, design, system, program, discovery, invention, improvement or writing (including renewals, extensions, continuations, divisions or continuations in pat thereof), you hereby irrevocably designate and appoint Blackboard and its officers and agents, as your agents and attorneys-in-fact to act for and on your behalf and instead of you, to execute and file any such application and to do all other lawfully permitted acts to further the prosecution and issuance of patents thereon with the same legal force and effect as if executed by you.

(B) You will aid Blackboard promptly on request, and without further consideration, in any matter pertaining to or relating to the protection of any of the Improvements, Inventions, applications for patents covering Inventions or Improvements, and/or Copyrighted Works. If such request is made after your employment has ended, Blackboard will reimburse you for any expenses incurred and compensate for any services rendered in complying with such request at the same rate at which you were compensated during the final month of your employment.

You agree that these provisions are necessary to protect Blackboard’s legitimate business interests. You warrant that the provisions will not unreasonably interfere in your ability to earn a living or to pursue your occupation after the Termination Date. You agree to notify any person or entity to which you provide services during the Restricted Period of your obligations under this Section 9.

10. Non-Disparagement. You agree to refrain from making any derogatory or defamatory remarks or comments that may disparage Blackboard, or any officer, employee or agent of Blackboard during your employment or after your Termination Date.

11. Other Obligations. You warrant that you are not subject to any other obligations that would conflict with or inhibit your ability to perform your duties under this Agreement. You represent that you have disclosed to Blackboard the existence and contents of all covenants not to compete that you have entered into with any other entity. You further warrant that you have not and will not bring to Blackboard or use in the performance of your responsibilities at Blackboard any equipment, supplies, facility or trade secret information (that is not generally available to the public) of any current or former employer or organization other than Blackboard to which you provided services, unless you have obtained written authorization for their possession and use.

12. Miscellaneous Provisions.

(a) Notices. Unless otherwise provided herein, any notice or other communication required to be given under the terms of this Agreement must be in writing and must be personally delivered (i.e., left with an individual 18 years of age or older) or sent by overnight delivery. Documents sent by overnight delivery will be presumed received on the next business day following the day sent.

(b) Dispute Resolution.

(c) Nature of Agreement. This Agreement and the attachment hereto constitute the entire agreement between you and Blackboard and supercede all prior agreements and understandings between you and Blackboard relating to the matters covered by this Agreement, except for the existing stock option agreements between you and Blackboard, which remain in full force and effect. Any long-term equity incentives between Blackboard and you shall be contained in a separate agreement. In making this Agreement, the parties warrant that they did not rely on any representations or statements other than those contained in this Agreement. No modification of or amendment to this Agreement will be effective unless in writing and signed by Blackboard’s General Counsel. A delay or failure by Blackboard to exercise any right that is the subject of this Agreement will not be construed as a waiver of that right. A waiver of a breach on any one occasion will not be construed as a waiver of any other breach. Regardless of the choice of law provisions of the District of Columbia or any other jurisdiction, the parties agree that this Agreement shall be otherwise interpreted, enforced and governed by the laws of the District of Columbia. This Agreement will continue in effect until all obligations under it are fulfilled. If any part of this Agreement is held by a court of competent jurisdiction to be void or unenforceable, the remaining provisions shall continue with full force and effect. This Agreement is not assignable by you. This Agreement is binding on you with respect to Blackboard, its successors or assigns. This Agreement may be executed in any number of counterparts each of which shall be an original, but all of which together shall constitute one instrument. The headings in this Agreement are for convenience only and shall not effect the interpretation of this Agreement. You further certify that you fully understand the terms of this Agreement and have entered into it knowingly and voluntarily.

IN WITNESS WHEREOF, each of the parties has executed this Agreement, in the case of Blackboard by its authorized officer, as of the day and year set forth under their signatures below.
