1.2 Trade Secrets and Confidential Information.

1.3 Noncompetition.

(a) Acknowledgment. Shareholder acknowledges that Radiant would not consummate the transactions contemplated by the Exchange Agreement, the Separation Agreement and the Ancillary Agreements without the assurance that Shareholder will not engage in the transactions and activities prohibited by this Section 1.3 as and for the periods set forth herein. In order to induce Radiant to consummate the Separation, the Exchange and the other transactions contemplated by the Exchange Agreement, the Separation Agreement and the Ancillary Agreements, Shareholder agrees to the restrictions set forth in this Section 1.3.

(b) Trade Name. Except as otherwise specifically provided in any Ancillary Agreement, Shareholder hereby agrees that, during the Noncompetition Period, Shareholder will not, directly or by assisting others, own, manage, operate, join, control, or participate in the ownership, management, operation, or control of any business conducted under any current corporate, product, or trade name or trademark of, Radiant, or name or mark similar thereto, other than any name or mark included in the Enterprise Assets (as defined in the Separation Agreement), without the prior written consent of Radiant.

(c) Noncompetition Covenant. Except as otherwise specifically provided in any Ancillary Agreement, Shareholder agrees that, during the Restricted Competition Period, Shareholder shall not, in the Restricted Territory, directly or indirectly (i) engage in the development or sale of Competitive Offerings on his own behalf or (ii) own any interest in, or engage in or perform any development of service for any Person other than Radiant that develops or sells Competitive Offerings in the Restricted Territory, either as a partner, owner, consultant, or shareholder, if such Person either (A) derives revenues from software associated with Competitive Offerings on an annual basis in excess of $20 million or (B) derives revenues from software and hardware (either independently from, or in addition to, software) associated with Competitive Offerings on an annual basis in excess of $50 million. Notwithstanding the foregoing, nothing contained in this Section 1.3(c) shall prohibit Shareholder, directly or indirectly, from (x) entering strategic alliances, joint ventures or similar contractual commercial relationships with any Person (other than Radiant) for purposes of marketing, selling and distributing any Enterprise Assets, including the Products, or (y) holding and making investments in securities of any Person (other than Radiant) whose securities are traded on a national securities exchange or are quoted on Nasdaq or an over-the-counter market, provided that Shareholder’s equity interest in any such Person does not exceed five percent (by voting power) of the outstanding shares of capital stock of such Person.

(d) Nonsolicitation. Shareholder hereby agrees that Shareholder will not, during the Nonsolicitation Period, directly or indirectly, solicit or recruit on behalf of Enterprise any employee of Radiant or its Subsidiaries as of the Separation without the prior written consent of Radiant; provided however, that nothing in this Section 1.3(d) shall (i) prohibit the hiring of any natural person who applied for employment with Enterprise solely in response to any public medium advertising, or (ii) prohibit the hiring of any natural person whose employment with Radiant or any of its Subsidiaries terminated at least three (3) months prior to the date of such solicitation or recruitment for a bona fide reason not designed or intended to circumvent the

-3-

provisions of this Section 1.3(d), so long as such natural person was not solicited or recruited by Shareholder prior to the expiration of such three (3) month period.

(e) Conduct of Enterprise. Shareholder hereby agrees that, during the relevant period, Shareholder will use his best efforts to cause Enterprise to comply with covenants of Enterprise set forth in Sections 2.9 and 2.10 of the Separation Agreement.

1.4 Severability. If a judicial determination is made that any of the provisions of this Agreement constitutes an unreasonable or otherwise unenforceable restriction against Shareholder, the provisions of this Agreement shall be rendered void only to the extent that such judicial determination finds such provisions to be unreasonable or otherwise unenforceable with respect to Shareholder. In this regard, Shareholder hereby agrees that any judicial authority construing this Agreement shall be empowered to sever any portion of the Territory, any prohibited business activity or any time period from the coverage of this Agreement, and to apply the provisions of this Agreement to the remaining portion of the Territory, the remaining business activities, and the remaining time period not so severed by such judicial authority. Moreover, notwithstanding the fact that any provision of this Agreement is determined not to be specifically enforceable, Radiant shall nevertheless be entitled to recover monetary damages as a result of the breach of such provision by Shareholder.

1.5 Injunctive Relief. Shareholder hereby agrees that any remedy at law for any breach of the provisions contained this Agreement shall be inadequate and that Radiant shall be entitled to seek injunctive relief in addition to any other remedy Radiant might have under this Agreement. Shareholder agrees that if any court of competent jurisdiction should enjoin any breach of this Agreement upon the request of Radiant, Shareholder specifically releases Radiant from the requirement of posting bond in connection with temporary or interlocutory injunctive relief, to the extent permitted by law.

1.6 Indemnification. Shareholder hereby agrees to indemnify and hold harmless, to the fullest extent permitted by law, Radiant from, against and in respect of any and all losses, damages, deficiencies, awards, assessments, judgments, fines, penalties, costs and expenses (including, but not limited to, reasonable legal fees and expenses) actually incurred as a result of any breach or default in performance by Shareholder of any covenant or agreement of Shareholder contained in this Agreement.

Section 2. Representations and Warranties of Shareholder. Shareholder hereby represents and warrants to Radiant that: (a) Shareholder has the right, power and capacity to execute, deliver and perform this Agreement, (b) this Agreement has been duly executed and delivered by Shareholder and constitutes a legal, valid and binding obligation of Shareholder enforceable against Shareholder in accordance with its terms, and (c) the execution, delivery and performance by Shareholder of Shareholder’s obligations under this Agreement will not, with or without the giving of notice or the lapse of time, or both, (i) violate any provision of any federal, state or local or any foreign statute, law, rule, regulation, ordinance, code, order, judgment, decree or any other requirement or rule of law applicable to Shareholder, or (ii) violate, conflict with, or result in a breach or default under, or cause the termination of, any term or condition of any court order, agreement, document or other instrument to which Shareholder is a party or by which Shareholder is bound.
