Optionee shall not, other than on the Company Group’s behalf, at any time during Optionee’s employment with the Company Group and thereafter, make available, divulge, disclose, or communicate in any manner whatsoever to anyone including, but not limited to, any person, firm, corporation, investor, member of the media, or entity, any such confidential or proprietary information, or use any such confidential or proprietary information for any purpose other than on the Company Group’s behalf, unless authorized to do so in writing by the Chairman of the Board, required by law or court order, or such information has become publicly available other than by reason of a breach by Optionee of this Section 3.1 or of another individual’s or entity’s violation of an obligation not to disclose such information, which obligation is known to Optionee. Should Optionee be required by law or court order to disclose such confidential or proprietary information, Optionee shall give the Chairman of the Board reasonable notice so as to allow the Company Group sufficient opportunity to challenge such application of the law or court order, or to otherwise attempt to limit the scope of such disclosure. This Agreement applies to all confidential and proprietary information of the Company Group, regardless of when such information is or was disclosed to Optionee.

3.2. Non-Competition; Non-Solicitation. During Optionee’s employment with the Company Group and for a period of two (2) years thereafter Optionee shall not, directly or indirectly, other than on the Company Group’s behalf:

(i) Engage in any capacity in the Business in the continental United States or in any other geographic area where the Company Group manufactures, markets, distributes or sells its products or renders services within the twenty-four (24) month period ending on the last day on which Optionee is in the employment of the Company Group or otherwise actively involved in the operation or management of the Business (the “Termination Date”), including as an owner, employee, partner, investor, or independent contractor, provided that nothing in this Section 3.2(i) shall prevent Optionee from owning less than five percent (5%) of any class of publicly traded securities of any such business so long as such investment is passive and Optionee has no other involvement with the issuer of such securities;

(ii) Induce or assist in the inducement of any employee or independent contractor, including sales representatives or agents, to terminate or otherwise limit their relationship with the Company Group; or

(iii) Solicit any customer or potential customer of the Company Group with respect to the Business. For purposes of this Section 3.2(iii), a customer means any individual or entity to

which the Company Group sold products or services within the twenty-four (24) month period immediately preceding the Termination Date. For purposes of this Section 3.2(iii), potential customer means any individual or entity to which the Company Group solicited in writing within the twelve (12) month period that immediately preceded the Termination Date.

3.3. Non-Disparagement. At no time shall Optionee, directly or indirectly, make (or cause to be made) to any person any disparaging, derogatory or other negative or false statement about or with respect to the Company Group (including its products, services, policies, practices, operations, employees, sales representatives, agents, officers, members, managers, partners or directors).

3.4. Patents, Copyrights, Trademarks and Other Property Rights. Any and all inventions, improvements, discoveries, formulas, technology, business strategies, management, administration, and accounting systems, processes, and computer software relating to the Company Group’s business (whether or not patentable), discovered, developed, or learned by Optionee during his or her employment with the Company Group are the sole and absolute property of the Company Group and are “works made for hire” as that term is defined in the copyright laws of the United States. The Company Group is the sole and absolute owner of all patents, copyrights, trademarks, and other property rights to those items and Optionee will fully assist the Company Group, at the Company Group’s cost and expense, to obtain the patents, copyrights, trademarks, or other property rights to all such inventions, improvements, discoveries, formulas, technology, business strategies, management, administration, and accounting systems, processes, or computer software. Optionee has been notified by the Company Group and understands that the foregoing provisions of this Section 3.4 do not apply to an invention for which no equipment, supplies, facilities, confidential, proprietary, or trade secret information of the Company Group was used and which was developed entirely on Optionee’s own time, unless the invention: (i) relates directly to the business of the Company Group; (ii) relates directly to the Company Group’s actual or demonstrably anticipated research and development, or (iii) results from any work performed by Optionee for the Company Group.

3.5. Protected Rights. Nothing contained in this Agreement or otherwise limits Optionee’s ability to report possible violations of law or regulation to, or file a charge or complaint with, the Securities and Exchange Commission, the Equal Employment Opportunity Commission, the National Labor Relations Board, the Occupational Safety and Health Administration, the Department of Justice, the Congress, any Inspector General, or any other federal, state or local governmental agency or commission (“Government Agencies”). This Agreement does not limit Optionee’s ability to communicate with any Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to the Company. Nothing in this Agreement shall limit Optionee’s ability under applicable U.S. federal law to (a) disclose in confidence trade secrets to federal, state, and local government officials, or to an attorney, for the sole purpose of reporting or investigating a suspected violation of law or (b) disclose trade secrets in a document filed in a lawsuit or other proceeding, but only if the filing is made under seal and protected from public disclosure.

3.6. Scope of Covenants. Participant hereby acknowledges and agrees that the covenants and the territorial, time, activity and other limitations set forth in this Section 3 (or the lack thereof, as the case may be) are commercially reasonable and are properly required to protect the Company Group and its members’ respective businesses. If any such territorial, time or activity limitation (or the lack thereof) is determined to be unreasonable or otherwise unenforceable by a court or other tribunal or competent jurisdiction, the parties agree to the reduction of such territorial, time or activity limitations (including the imposition of such a limitation if it is missing) to such an area, period, scope of

activity or other limitation as said court or other tribunal shall deem reasonable and enforceable under the circumstances. Also, if any member of the Company Group seeks partial enforcement of this Section 3 as to only a territory, time, scope of activity or other limitation that is reasonable, then such member of the Company Group shall be entitled to such reasonable partial enforcement. If such reduction or (if any member of the Company Group seeks partial enforcement) such partial enforcement is not possible, or if a court or other tribunal of competent jurisdiction declines for any or no reason to grant such reduction or partial enforcement, as applicable, then the unenforceable provision or portion thereof shall be severed as provided in Section 5.4, without affecting the remaining provisions of this Agreement.

3.7. Tolling. The period of time in which Optionee is required to act, or refrain from acting, pursuant to this Section 3 shall be tolled (shall not run) for so long as Optionee is in breach of any of Optionee’s obligations hereunder.

3.8. Business. For purposes of this Section 3, “Business” shall mean the business activities conducted by or planned to be undertaken by the Company Group while Optionee is a holder of any Common Stock acquired pursuant to the exercise of this Option or while Optionee is employed by the Company Group, including any business involving the design, engineering, manufacture or sale of heat tracing systems (for example, products involving the application of external heat to pipes, vessels, instruments or other equipment for the purposes of freeze protection, process temperature maintenance, environmental monitoring or surface snow and ice melting, heat tracing equipment, heat tracing tubing bundles, and heat tracing control systems), heat tracing system consultation, heat tracing system installation, heat tracing system maintenance and any other products sold or services provided by the Company Group and the provision of related services.

4. Additional Terms and Conditions of Option.

4.1. Nontransferability of Option. The Option may not be transferred by Optionee other than by will or the laws of descent and distribution or pursuant to the designation of one or more beneficiaries on the form prescribed by the Company. Except to the extent permitted by the foregoing sentence, (i) during Optionee’s lifetime the Option is exercisable only by Optionee or Optionee’s legal representative, guardian or similar person and (ii) the Option may not be sold, transferred, assigned, pledged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar process. Upon any attempt to so sell, transfer, assign, pledge, hypothecate, encumber or otherwise dispose of the Option, the Option and all rights hereunder shall immediately become null and void.

4.2. Investment Representation. Optionee hereby represents and covenants that (a) any shares of Common Stock purchased upon exercise of the Option will be purchased for investment and not with a view to the distribution thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”), unless such purchase has been registered under the Securities Act and any applicable state securities laws; (b) any subsequent sale of any such shares shall be made either pursuant to an effective registration statement under the Securities Act and any applicable state securities laws, or pursuant to an exemption from registration under the Securities Act and such state securities laws; and (c) if requested by the Company, Optionee shall submit a written statement, in a form satisfactory to the Company, to the effect that such representation (x) is true and correct as of the date of any purchase of any shares hereunder or (y) is true and correct as of the date of any sale of any such shares, as applicable. As a further condition precedent to any exercise of the Option, Optionee shall comply with all regulations and requirements of any regulatory authority having control of or supervision over the issuance or

delivery of the shares and, in connection therewith, shall execute any documents which the Board or the Committee shall in its sole discretion deem necessary or advisable.

4.3. Withholding Taxes. (a) As a condition precedent to the issuance of Common Stock upon exercise of the Option, Optionee shall, upon request by the Company, pay to the Company in addition to the purchase price of the shares, such amount as the Company may be required, under all applicable federal, state, local or other laws or regulations, to withhold and pay over as income or other withholding taxes (the “Required Tax Payments”) with respect to such exercise of the Option. If Optionee shall fail to advance the Required Tax Payments after request by the Company, the Company may, in its discretion, deduct any Required Tax Payments from any amount then or thereafter payable by the Company to Optionee.

(b) Optionee may elect to satisfy his or her obligation to advance the Required Tax Payments by any of the following means: (1) a cash payment to the Company, (2) delivery to the Company (either actual delivery or by attestation procedures established by the Company) of previously owned whole shares of Common Stock having an aggregate Fair Market Value, determined as of the Tax Date, equal to the Required Tax Payments, (3) authorizing the Company to withhold whole shares of Common Stock which would otherwise be delivered to Optionee upon exercise of the Option having an aggregate Fair Market Value, determined as of the Tax Date, equal to the Required Tax Payments, (4) except as may be prohibited by applicable law, a cash payment by a broker-dealer acceptable to the Company to whom Optionee has submitted an irrevocable notice of exercise or (5) any combination of (1), (2) and (3). Shares of Common Stock to be delivered or withheld may not have a Fair Market Value in excess of the minimum amount of the Required Tax Payments. Any fraction of a share of Common Stock which would be required to satisfy any such obligation shall be disregarded and the remaining amount due shall be paid in cash by Optionee or deducted from any amount then or thereafter payable by the Company to the Holder. No certificate representing a share of Common Stock shall be issued or delivered until the Required Tax Payments have been satisfied in full.

4.4. Adjustment. In the event of any stock split, stock dividend, recapitalization, reorganization, merger, consolidation, combination, exchange of shares, liquidation, spin-off or other similar change in capitalization or event, or any distribution to holders of Common Stock other than a regular cash dividend, the number and class of securities subject to the Option and the Exercise Price shall be equitably adjusted by the Committee and in accordance with Section 409A of the Code. The decision of the Committee regarding any such adjustment shall be final, binding and conclusive. If any such adjustment would result in a fractional security being subject to the Option, the Company shall pay Optionee, in connection with the first exercise occurring after such adjustment, an amount in cash determined by multiplying (i) the fraction of such security (rounded to the nearest hundredth) by (ii) the excess, if any, of (A) the Fair Market Value on such date over (B) the Exercise Price of the Option.

4.5. Change in Control. In the event of a Change in Control, the Option shall be subject to Section 5.8 of the Plan.

4.6. Compliance with Applicable Law. The Option is subject to the condition that if the listing, registration or qualification of the shares subject to the Option upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in connection with, the purchase or issuance of shares hereunder, the Option may not be exercised, in whole or in part, and such shares may not be issued, unless such listing, registration, qualification, consent, approval or other action shall have been effected or

obtained, free of any conditions not acceptable to the Company. The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent, approval or other action.

4.7. Issuance or Delivery of Shares. Upon the exercise of the Option, in whole or in part, the Company shall issue or deliver, subject to the conditions of this Section 4, the number of shares of Common Stock purchased against full payment therefor.

The Company shall pay all original issue or transfer taxes and all fees and expenses incident to such issuance, except as otherwise provided in Section 4.3.

4.8. Option Confers No Rights as Stockholder. Optionee shall not be entitled to any privileges of ownership with respect to shares of Common Stock subject to the Option unless and until such shares are purchased and issued upon the exercise of the Option, in whole or in part, and Optionee becomes a stockholder of record with respect to such issued shares. Optionee shall not be considered a stockholder of the Company with respect to any such shares not so purchased and issued.

4.9. Option Confers No Rights to Continued Employment. In no event shall the granting of the Option or its acceptance by Optionee, or any provision of this Agreement or the Plan, give or be deemed to give Optionee any right to continued employment by the Company, any Subsidiary or any affiliate of the Company or affect in any manner the right of the Company, any Subsidiary or any affiliate of the Company to terminate the employment of any person at any time.
