B. The [Stockholder/Employee] acknowledges that [he/she] will derive an economic benefit from the consideration to be paid under retention bonus to be paid to Employee pursuant to the terms of the Merger Agreement.

AGREEMENT

NOW THEREFORE, as a material inducement to Parent to enter into and consummate the transactions contemplated by the Merger Agreement, and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereby agree as follows:

1. Term and Consideration. The term of this Agreement shall commence on the Closing Date and shall expire on the fifth (5^th) anniversary of the [Closing Date/date of termination of [Stockholder/Employee]’s employment with the Company]¹ (the “Term”).² In the event Stockholder is in breach of Sections 2 or 3 of this Agreement, the Term shall be extended by the length of any period during which [Stockholder/Employee] is in breach of the terms of such Sections. No additional consideration shall be paid to [Stockholder]/Employee] pursuant to this Agreement.

2. Covenant Not To Compete. During the Term, neither Stockholder nor any of its subsidiaries or Affiliates, Stockholder shall, directly or indirectly, (a) engage in any business

anywhere in North America that engages in the business of water treatment solutions or services, including applications for (i) arsenic or nitrate removal for utilities, cities, municipalities, special districts, real estate developers and other entities that supply water, and (ii) industrial operations that may require mobile de-ionization services, metals removal using ion exchange, and special use of ion exchange (the “Business”) or (b) own an interest in, manage, operate, join, control, lend money or render financial or other assistance to or participate in or be connected with, as an officer, employee, manager, member, consultant or otherwise, any person that competes with Parent or the Company in the Business (such person, a “Competitor”); provided, however, that, for the purposes of this Section 2, ownership of securities having no more than one percent of the outstanding voting power of any Competitor which are listed on any national securities exchange shall not be deemed to be in violation of this Section 2 as long as the person owning such securities has no other connection or relationship with such Competitor.

3. No Solicitation of Customers and Employees.

a. During the Term, neither [Stockholder/Employee] nor any of its subsidiaries or Affiliates shall, directly or indirectly, call on or solicit, divert or take away from Parent or the Company (including without limitation by divulging to any Competitor or potential Competitor) any person, firm, corporation or other entity who is or which at the Closing Date was a customer or supplier of Parent or the Company or whose identity is known to [Stockholder/Employee] at the Closing Date as one whom the Company intends to solicit.

b. During the Term, [Stockholder/Employee] shall not and shall cause its Affiliates not to, in any way, directly or indirectly, induce or attempt to induce any officers, employees, representatives or agents of the Company to leave the employ of the Company or violate the terms of their contracts, or any employment arrangements, with the Company.

4. Essential Element of Parent’s Bargain. [Stockholder/Employee] acknowledges that the covenants set forth in Sections 2 and 3 are an essential element of the Merger Agreement and that, but for [Stockholder/Employee]’s agreement to comply with these covenants, Parent would not have entered into the Merger Agreement. [Stockholder/Employee] hereby acknowledges that (i) this Agreement constitutes an independent covenant that shall not be affected by performance or nonperformance of any other provision of the Merger Agreement by Parent and (ii) the consummation of the transactions contemplated by the Merger Agreement and the [Merger Consideration/retention bonus] [Stockholder/Employee] receives for its shares of the Company shall constitute the consideration for such independent covenant. [Stockholder/Employee] has independently consulted with its counsel (or has been advised by Parent to consult such counsel) and after such consultation (or advice to seek consultation) [Stockholder/Employee] agrees that the covenants and consideration set forth in this Agreement are reasonable and proper.

5. Severability of Provisions. In the event that the provisions of Section 2 or Section 3 should ever be adjudicated by a court of competent jurisdiction to exceed the time or geographic or other limitations permitted by applicable law, then such provisions shall be deemed reformed to the maximum time or geographic or other limitations permitted by applicable law, as determined by such court in such action. Without limiting the foregoing, the covenants contained herein shall be construed as separate covenants, covering their respective

subject matters, with respect to (a) each of the separate cities, counties and states in which any of [Stockholder/Employee] or its subsidiaries or Affiliates transacts any business and (b) [Stockholder/Employee] and its subsidiaries and Affiliates separately.

6. Injunctive Relief. [Stockholder/Employee] acknowledges that (a) the provisions of Section 2 and Section 3 are reasonable and necessary to protect the legitimate interests of Parent, and (b) any violation of Section 2 or Section 3 will result in irreparable injury to Parent, the exact amount of which will be difficult to ascertain, and that the remedies at law for any such violation would not be reasonable or adequate compensation to Parent for such a violation. Accordingly, if [Stockholder/Employee] violates the provisions of Section 2 or Section 3, in addition to any other remedy that may be available at law or in equity, Parent shall be entitled to specific performance and injunctive relief, without posting bond or other security, and without the necessity of proving actual damages or showing that money damages are inadequate.

7. Governing Law. This Agreement shall be construed under and governed by the internal laws of the State of Tennessee without regard to its conflict of laws provisions.

All notices shall be addressed to a party at the address listed for such party in the Merger Agreement or at such other address as such party may specify by like notice.
