Exhibit 99.2

AMENDED CHANGE IN CONTROL AND TERM EMPLOYMENT AGREEMENT

This AMENDED CHANGE IN CONTROL AND TERM EMPLOYMENT AGREEMENT (“Agreement”) is entered into by and between AmeriVest Properties Inc., a Maryland corporation (the “Company”), with offices at 1780 South Bellaire Street, Suite 100, Denver, Colorado 80222, and John B. Greenman (the “Executive”), an individual residing in the State of Colorado, dated as of this 31st day of August, 2005. For convenience, at times Company and Executive shall be referred to herein as the “Parties.”

WHEREAS, the Company recognizes that the current business environment makes it difficult to attract and retain highly qualified executives unless a certain degree of security can be offered to such individuals against organizational and personnel changes which frequently follow changes in control of a corporation; and

WHEREAS, even rumors of acquisitions or mergers may cause executives to consider major career changes in an effort to assure financial security for themselves and their families; and

WHEREAS, the Company desires to assure fair treatment of Executive during his employment with the Company and in the event of a Change in Control (as defined below) and to allow him to make critical career decisions without undue time pressure and financial uncertainty, thereby increasing his willingness to remain with the Company notwithstanding the outcome of a possible Change in Control transaction; and

WHEREAS, the Company recognizes that Executive will be involved in evaluating or negotiating any offers, proposals or other transactions which could result in Changes in Control of the Company and believes that it is in the best interest of the Company and its stockholders for the Executive to be in a position, free from personal financial and employment considerations, to be able to assess objectively and pursue aggressively the interests of the Company’s stockholders in making these evaluations and carrying on such negotiations; and

WHEREAS, the Board of Directors (the “Board”) of the Company believes it is essential to provide the Executive with compensation arrangements during his employment with the Company and upon a Change in Control to provide the Executive with individual financial security in a manner competitive with other corporations, and in order to accomplish these objectives, the Board has caused the Company to enter into this Agreement.

NOW THEREFORE, the Parties, for good and valuable consideration, the legal sufficiency of which is hereby acknowledged, and intending to be legally bound, agree as follows:

1. Employment. Upon and subject to the terms provided herein, the Company agrees to employ Executive, and Executive agrees to be employed by the Company, as the Company’s Chief Investment Officer as set forth in Section 4 of this Agreement.

2. Operation and Term of Agreement. This Agreement shall be effective immediately upon its execution. This Agreement may be terminated by the Company upon 24 months’ advance written notice to the Executive, except as otherwise provided in Section 4 of this Agreement; and provided, however, that after a Change in Control of the Company during

the term of this Agreement, this Agreement shall remain in effect until all of the obligations of the Parties under this Agreement are satisfied and the Protection Period has expired. Prior to a Change in Control, this Agreement shall immediately terminate upon termination of the Executive’s employment or upon the Executive’s ceasing to be an elected officer of the Company.

3. Certain Definitions. For purposes of this Agreement, the following words and phrases shall have the following meanings:

(a) “Cause” shall mean (i) the continued failure by the Executive to perform his material responsibilities and duties toward the Company (other than any such failure resulting from the Executive’s incapacity due to physical or mental illness), (ii) the engaging by the Executive in willful or reckless conduct that is demonstrably injurious to the Company monetarily or otherwise, (iii) the conviction of the Executive of a felony, or (iv) the commission or omission of any act by the Executive that is materially inimical to the best interests of the Company and that constitutes on the part of the Executive common law fraud or malfeasance, misfeasance, or nonfeasance of duty; provided, however, that “cause” shall not include the Executive’s lack of professional qualifications. For purposes of this Agreement, an act, or failure to act, on the Executive’s part shall be considered “willful” or “reckless” only if done, or omitted, by him not in good faith and without reasonable belief that his action or omission was in the best interest of the Company. The Executive’s employment shall not be deemed to have been terminated for “cause” unless the Company shall have given or delivered to the Executive (A) reasonable notice setting forth the reasons for the Company’s intention to terminate the Executive’s employment for “cause,” (B) a reasonable opportunity, at any time during the 30-day period after the Executive’s receipt of such notice, for the Executive, together with his counsel, to be heard before the Board, and (C) a Notice of Termination (as defined in Section 13 below) stating that, in the good faith opinion of not less than a majority of the entire membership of the Board, the Executive was guilty of the conduct set forth in clauses (i), (ii), (iii) or (iv) of the first sentence of this Section 3(a).

(b) “Change in Control” shall mean a change in control under Code Section 409A(a)(2). As provided in Internal Revenue Service Notice 2005-1, a change of control would include (A) any person (or more than one person acting as a group) becoming the beneficial owner, directly or indirectly, of securities of the Company representing 35 percent or more of the combined voting power of the Company’s then outstanding securities; or (B) during any 12-month period, the following persons cease for any reason to constitute a majority of the Board: individuals who at the beginning of such period constitute the Board and new Directors each of whose election to the Board or nomination for election to the Board by the Company’s security holders was approved by a vote of more than 50 percent of the Directors then still in office who either were Directors at the beginning of the period or whose election or nomination for election was previously so approved; or (C) the security holders of the Company approve a merger or consolidation of the Company with any other corporation, other than a merger or consolidation that would result in the voting securities of the Company outstanding immediately before the merger or consolidation continuing to represent (either by remaining outstanding or by being converted into voting securities of the Company or of such surviving entity) at least eighty percent (80%) of the total voting power represented by the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation. A Change of Control will be deemed to have occurred if the security holders of the Company approve a plan

of complete liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets.

(d) “Disability,” for purposes of this Agreement, shall mean total disability as defined in any long-term disability plan sponsored by the Company in which the Executive participates, or, if there is no such plan or it does not define such term, then it shall mean the physical or mental incapacity of the Executive that prevents him from substantially performing the duties of the office or position to which he was elected or appointed by the Board for a period of at least 180 days and the incapacity is expected to be permanent and continuous through the Executive’s 65th birthday.

(e) The “Change in Control Date” shall be any date during the term of this Agreement on which a Change in Control occurs. Anything in this Agreement to the contrary notwithstanding, if the Executive’s employment or status as an elected officer with the Company is terminated within six (6) months before the date on which a Change in Control occurs, and it is reasonably demonstrated that such termination (i) was at the request of a third party who has taken steps reasonably calculated or intended to effect a Change in Control or (ii) otherwise arose in connection with or anticipation of a Change in Control, then for all purposes of this Agreement the “Change in Control Date” shall mean the date immediately before the date of such termination.

(f) “Good Reason” means:

(i) the assignment to the Executive within the Protection Period of any duties inconsistent in any respect with the Executive’s position (including status, offices, titles and reporting requirements, authority, duties or responsibilities), or any other action that results in a diminution in such position, authority, duties, or responsibilities excluding for this purpose an isolated, insubstantial, and inadvertent action not taken in bad faith and that is remedied by the Company promptly after receipt of notice given by the Executive;

(ii) a reduction by the Company in the Executive’s base salary in effect immediately before the beginning of the Protection Period or as increased from time to time after the beginning of the Protection Period;

(iii) a failure by the Company to maintain plans providing benefits at least as beneficial as those provided by any benefit or compensation plan (including, without limitation, any incentive compensation plan, bonus plan or program, retirement, pension or savings plan, life insurance plan, health and dental plan or disability plan) in which the Executive is participating immediately before the beginning of the Protection Period, or any action taken by the Company that would adversely affect the Executive’s participation in or reduce the Executive’s opportunity to benefit under any of such plans or deprive the Executive of any material fringe benefit enjoyed by him immediately before the beginning of the Protection Period; provided, however, that a reduction in benefits under the Company’s tax-qualified retirement, pension, or savings plans or its life insurance plan, health and dental plan, disability plans or other insurance plans, which reduction applies generally to participants in the plans and has a de minimis effect on the Executive shall not constitute “Good Reason” for termination by the Executive;

(iv) the Company’s requiring the Executive, without the Executive’s written consent, to be based at any office or location in excess of 50 miles from his office location immediately before the beginning of the Protection Period, except for travel reasonably required in the performance of the Executive’s responsibilities;

(v) any purported termination by the Company of the Executive’s employment for Cause other than as referred to in Section 13 of this Agreement;

(vi) any failure by the Company to obtain the assumption of the obligations contained in this Agreement by any successor as contemplated in Section 12(c) of this Agreement;

(vii) a change in the location of the Executive’s office or the Company’s principal executive office to a place that is more than fifty (50) miles from the present location; or

(viii) any material breach of this Agreement by the Company.

(g) “Parent” means any entity that directly or indirectly through one or more other entities owns or controls more than 50 percent of the common stock and any other voting securities of the Company.

(h) “Protection Period” means the period beginning on the Change in Control Date and ending on the last day of the 30th full calendar month following the Change in Control Date.

(i) “Subsidiary” means a company 50 percent or more of the voting securities of which are owned, directly or indirectly, by the Company.

4. Term Employment Compensation.

These releases shall include, by way of example and not limitation, all claims which arise out of, relate to, or are based on (i) Executive’s employment and/or association with the Released Parties and the termination thereof, (ii) any and all contracts, binding promises and statements to, from or between the Parties, (iii) the common laws of any state, (iv) Title VII of the Civil Rights Act of 1964, as amended, (v) claims under the Civil Rights Act of 1991, (vi) claims under 42 U.S.C. § 1981, § 1981a, § 1983, § 1985, or § 1988, (vii) the Age Discrimination in Employment Act of 1967, as amended, (viii) the Employee’s Income Retirement Security Act of 1974, as amended, (ix) claims under the Older Workers Benefit Protection Act of 1990, and (x) claims under all other local, state and federal statutes, any of which could be raised, filed and/or brought in any court of competent jurisdiction and/or in any local, state and federal administration agency or administration. However, Executive does not release any claims he may have under any stock option or warrant agreements.

(i) Nothing contained herein shall be construed as a release of any claim the Executive may have to unemployment benefits. Executive may make a claim for such benefits, and the Released Parties will provide truthful information in response to questions from the responsible State agency.

(ii) Notwithstanding the recitation of the claims set forth in this Section 4(f), or whether quoted herein or not, and for the purpose of effectuating a full and final release herein between the Parties, Executive expressly acknowledges that all releases agreed to by Executive in this Section 4(f) are intended to include and contemplate the extinguishment, without limitation, of all claims which he now has or does not know or suspect to exist in his favor at the time of the execution hereof.

(g) Executive Warranties. Executive warrants and represents as follows:

(i) Executive has full and complete legal capacity to enter into this Agreement, has read this Agreement, has had a reasonable time to consider its terms, and agrees to the conditions and obligations set forth in it.

(ii) Executive has had twenty-one (21) days to consider the Agreement, and, if Executive executes this Agreement within less than twenty-one (21) days from the date of receipt, it is with the express understanding that Executive had the full twenty-one (21)

days available if so desired. Further, Executive waives all rights to a twenty-one (21) day period to consider the terms of Employee’s release of claims under the Age Discrimination in Employment Act (“ADEA”) if Executive signs this Agreement prior to the expiration of the twenty-one (21) day period.

(iii) Executive has not relied on any statement made by the Company, its agents or representatives, either express or implied, or by statement or omission, in making his decision to enter into this Agreement. Executive voluntarily executes this Agreement after having been advised by the Company to seek legal counsel, and has had full opportunity to consult with legal counsel, and without being pressured or influenced by any person, or by any statement or representation of any person acting on behalf of another Party, including the officers, agents and attorneys for any other Party.

(iv) Executive has been informed and understands that (i) to the extent that this Agreement waives or releases any claims Executive might have under the ADEA, Executive may rescind such waiver and release within seven (7) calendar days of the execution of this Agreement, and (ii) any such rescission must be in writing and hand delivered to the Company, or, if sent by mail, postmarked within the seven (7) day period, sent only by certified mail, return receipt requested, and addressed to the Company.

(v) This Agreement is subject to the terms of the Older Workers Benefit Protection Act of 1990 (“OWBPA”). Executive acknowledges and agrees that he is, voluntarily and with full knowledge of the consequences of such release, releasing all claims, including any claims Executive has or could have brought under the OWBPA and any claim(s) under the ADEA.

(vi) Executive acknowledges and agrees that this Agreement is written in a manner intended to be understood, and that Executive understands this Agreement.

(vii) Executive has had a full and fair opportunity to investigate the facts underlying any claims that Executive believes he may have against the Company. Executive enters into this Agreement acknowledging that there may be facts of which he is not aware; but nonetheless enters into this Agreement with the intent of providing the Company, and its affiliates, with a full and final release of all known and unknown, suspected or unsuspected, foreseen or unforeseen, matured or unmatured, liquidated or unliquidated, claims, based on all known and unknown facts.

(h) Termination of Employment. Notwithstanding any other provision of this Agreement, Executive’s employment may be terminated as follows: (i) expiration of the Employment Period; (ii) termination for Cause; (iii) termination for Disability; (iv) termination upon a Change in Control; (v) termination for Good Reason; (vi) termination because of the death of Executive; (vii) termination without Cause; and (viii) resignation. The Executive and the Company shall be bound by all provisions of this Agreement specifically related to any benefit or obligation of the Executive or the Company under any of these circumstances.

(i) Code Section 409A Savings Provision. Notwithstanding anything in this Agreement to the contrary, the following provisions related to payments treated as deferred compensation under Code Section 409A shall apply:

(a) If, on the date of Executive’s “separation from service,” Executive is a “specified person,” within the meaning of Sections 409A(a)(2)(A)(i) and 409A(a)(2)(B)(i) of the Code, and as a result of such separation from service Executive would receive any payment that, absent the application of these provisions, would be subject to the constructive receipt, interest, and additional tax provisions of Code Section 409A(a), then any such payment shall be made on the date that is the earliest of: (i) six (6) months after Executive’s separation from service, (ii) Executive’s date of death, or (iii) such other earliest date for which such payment will not be subject to such constructive receipt, interest, and additional tax.

(b) It is the intention of the parties that all amounts payable under this Agreement not be subject to the constructive receipt, interest, and additional tax resulting from the application of Code Section 409A. To the extent such amounts could become subject to such constructive receipt, interest, and additional tax, the parties shall cooperate to amend this Agreement with the goal of giving Executive the same or equivalent value of the benefits described in this Agreement in a manner that does not result in such constructive receipt, interest, and additional tax. In the event the Company does not so cooperate, the Company shall indemnify Executive for any interest and additional tax arising from the application of Code Section 409A, grossed-up for any other income tax incurred by Executive related to the indemnification (i.e., indemnification of such additional income tax), assuming the highest marginal income tax rates apply to any taxable indemnification.

5. Vesting Upon Change of Control. Upon a Change of Control, any and all Common Shares, options, or other forms of securities issued by the Company and beneficially owned by the Executive (whether granted before or after the date of this Agreement) that are unvested, restricted, or subject to any similar restriction that would otherwise require continued ownership by the Executive beyond the Change of Control Date in order to be vested in the hands of the Executive shall vest automatically.

6. Benefits Upon Termination Within a Protection Period. If, during a Protection Period, the Executive’s employment is terminated by the Company other than for Cause or Disability or other than as a result of the Executive’s death or if the Executive terminates his employment for Good Reason, the Company shall, subject to Section 10, pay to the Executive in a lump sum in cash, within 10 days after the date of termination, the aggregate of the following amounts:

(a) an amount equal to the Executive’s full base salary and vacation pay (for vacation not taken) accrued but unpaid through the date of termination at the rate in effect at the time of the termination;

(b) a severance amount equal to 2.0 times the Executive’s “Annual Compensation.” For purposes of Section 6 and Section 7 of this Agreement, “Annual Compensation” shall be an amount equal to the sum of (i) the Executive’s annual base salary from the Company and its Subsidiaries (including scheduled base salary increases or increases that are budgeted and approved either by the Compensation Committee of the Board of Directors or by the Board of Directors of the Company in advance of the Change of Control Date), annualized for any partial year, and calculated based on the average for the three year period ending on the December 31 after the Change in Control Date (or of such shorter period if the Executive has not been employed since the commencement of the full three year period); and

(ii) the amount of annual bonus accrued by the Company for the Executive for the year before the Change of Control occurs; and

(c) upon surrender by the Executive of his outstanding options to purchase common shares of the Company (“Common Shares”) granted to the Executive by the Company (the “Outstanding Options”) and any stock appreciation rights (“SARs”), an amount in respect of each Outstanding Option and SAR (whether vested or not) equal to the difference between the exercise price of such Outstanding Options and SARs and the higher of (x) the fair market value of the Common Shares at the time of such termination (but not less than the closing price for the Common Shares on the New York Stock Exchange, or such other national stock exchange on which such shares may be listed, on the last trading day such shares traded prior to the date of termination), and (y) the highest price paid for Common Shares or, in the cases of securities convertible into Common Shares or carrying a right to acquire Common Shares, the highest effective price (based on the prices paid for such securities) at which such securities are convertible into Common Shares or at which Common Shares may be acquired, by any person or group whose acquisition of voting securities has resulted in a Change in Control of the Company; provided, however, that this Section 6(c) shall not apply to the surrender of any Outstanding Option that is an incentive stock option (within the meaning of section 422 of the Code).

(d) However, in the event Executive receives benefits pursuant to Section 4(e) or Section 7 of this Agreement, Executive shall automatically forfeit any benefits otherwise due and payable under this Section 6 of this Agreement.

If the Executive is terminated pursuant to this Section 6 and, in connection therewith, the Executive and the Company enter into a noncompetition agreement or a nonsolicitation agreement, unless otherwise agreed by the Executive and the Company, the amount payable to the Executive under the preceding provisions of this Section 6 shall be reduced by the amount payable to the Executive under such agreement(s).

7. Executive’s Right to Leave Employment. At any time during the six month period following a Change in Control Date, the Executive shall have the right to terminate the Executive’s employment with the Company at the Executive’s sole discretion (the “Executive Termination Right”). In the event the Executive exercises the Executive Termination Right, the Company shall pay the Executive in a lump sum in cash within 10 days after the date of termination the aggregate of the following amounts:

(a) The amounts set forth in Sections 6(a) and 6(c); and

(b) 1.0 times the Executive’s Annual Compensation.

(c) However, in the event Executive receives benefits pursuant to Section 4(e) or Section 6 of this Agreement, Executive shall automatically forfeit any benefits otherwise due and payable under this Section 7 of this Agreement.

If the Executive exercises the Executive Termination Right and, in connection therewith, the Executive and the Company enter into a noncompetition agreement or a nonsolicitation agreement, unless otherwise agreed by the Executive and the Company, the amount payable to

the Executive under the preceding provisions of this Section 7 shall be reduced by the amount payable to the Executive under such agreement(s).

8. Non-exclusivity of Rights. Nothing in this Agreement shall prevent or limit the Executive’s continuing or future participation in any benefit, bonus, incentive, or other plans, practices, policies, or programs provided by the Company or any of its Subsidiaries and for which the Executive may qualify, nor shall anything in this Agreement limit or otherwise affect such rights as the Executive may have under any stock option or other agreements with the Company or any of its Subsidiaries, except as otherwise specified in this Agreement. Amounts that are vested benefits or that the Executive is otherwise entitled to receive under any plan, practice, policy, or program of the Company or any of its Subsidiaries at or subsequent to the date of termination of employment shall be payable in accordance with such plan, practice, policy, or program; provided, however, that the Executive shall not be entitled to severance pay, or benefits similar to severance pay, except as otherwise set forth in this Agreement, under any plan, practice, policy, or program generally applicable to employees of the Company or any of its Subsidiaries.

9. Full Settlement; No Obligation to Seek Other Employment; Legal Expenses. The Company’s obligation to make the payments provided for in this Agreement and otherwise to perform its obligations under this Agreement shall not be affected by any set-off, counterclaim, recoupment, defense, or other claim, right, or action that the Company may have against the Executive or others, except as otherwise specified in this Agreement. The Executive shall not be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement. The Company agrees to pay, upon written demand by the Executive, all legal fees and expenses the Executive may reasonably incur as a result of any dispute or contest (regardless of outcome) by or with the Company or others regarding the validity or enforceability of, or liability under, any provision of this Agreement, except with respect to the provisions set forth in Sections 1 and 4 and any provision in this Agreement defining any term or terms referenced in Sections 1 and 4. In any such action brought by the Executive for damages or to enforce any provisions of this Agreement, he shall be entitled to seek both legal and equitable relief and remedies, including, without limitation, specific performance of the Company’s obligations under this Agreement, in his sole discretion.

10. Cut Back in Benefits. Notwithstanding any other provision of this Agreement, the cash lump sum or other payment(s) and other benefits otherwise to be provided pursuant to Sections 4, 5, 6 and 7 of this Agreement (the “Severance Benefit”) shall be reduced as described below if independent accountants for the Company (the “Accountants”) determine (A) that Executive would, by reason of section 4999 of the Code, be required to pay an excise tax on any part of the Severance Benefit or any part of any other payment or benefit to which Executive is entitled under any plan, practice, policy, or program, and (B) the amount of the Severance Benefit that Executive would retain on an after-tax basis, present value basis would be increased as a result of such reduction by an amount of at least $5,000. If the Severance Benefit is required to be reduced, it shall be reduced only to the extent required, in the opinion of the Accountants, to prevent the imposition upon the Executive of the tax imposed under section 4999 of the Code. The Company shall determine which elements of the Severance Benefit shall be reduced to conform to the provisions of this Section. Any determination made by the Accountants pursuant to this Section shall be conclusive and binding on the Executive. The Executive shall promptly

provide to the Company such information regarding the Executive tax situation as the Company shall reasonably request in order to allow the Accountants to perform calculations required by this Section 10.

11. Confidential Information. The Executive shall hold in a fiduciary capacity for the benefit of the Company all secret or confidential information, knowledge, or data relating to the Company or any of its Subsidiaries, and their respective businesses, obtained by the Executive during the Executive’s employment with the Company or any of its Subsidiaries and that has not become public knowledge (other than by acts of the Executive or his representatives in violation of this Agreement). After the date of termination of the Executive’s employment with the Company, the Executive shall not, without the prior written consent of the Company, communicate or divulge any such information, knowledge, or data to anyone other than the Company and those designated by it. In no event shall an asserted violation of the provisions of this Section constitute a basis for deferring or withholding any amounts otherwise payable to the Executive under this Agreement.

12. Successors.

(a) This Agreement is personal to the Executive and without the prior written consent of the Company shall not be assignable by the Executive otherwise than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by the Executive’s legal representatives or successor(s) in interest. The Executive may designate a successor (or successors) in interest to receive any and all amounts due the Executive in accordance with this Agreement should the Executive be deceased at any time of payment. Such designation of successor(s) in interest shall be made in writing and signed by the Executive, and delivered to the Company pursuant to Section 16(b). This Section 12(a) shall not supersede any designation of beneficiary or successor in interest made by the Executive, or separately covered, under any other plan, practice, policy, or program of the Company.

(b) This Agreement shall inure to the benefit of and be binding upon the Company and its successors and assigns.

(c) The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation, or otherwise) to all or substantially all of the business or assets of the Company and any Parent of the Company or any successor and without regard to the form of transaction utilized to acquire the business or assets of the Company, to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession or parentage had taken place. As used in this Agreement, “Company” shall mean the Company as defined above and any successor to its business or assets as aforesaid (and any Parent of the Company or any successor) that is required by this clause to assume and agree to perform this Agreement or which otherwise assumes and agrees to perform this Agreement.

13. Notice of Termination. Any termination of the Executive’s employment by the Company for Cause or by the Executive for Good Reason shall be communicated by Notice of Termination to the other party given in accordance with Section 16(b) of this Agreement. For purposes of this Agreement, a “Notice of Termination” means a written notice that (i) indicates the specific termination provision in this Agreement relied upon, (ii) sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive’s

employment under the provision so indicated, and (iii) if the date of termination is other than the date of receipt of such notice, specifies the termination date (which date shall be not more than 15 days after the giving of such notice). The failure by the Executive to set forth in the Notice of Termination any fact or circumstance that contributes to a showing of Good Reason shall not waive any right of the Executive under this Agreement or preclude the Executive from asserting such fact or circumstance in enforcing his rights.

14. Requirements and Benefits if Executive Is Employee of Subsidiary of Company. If the Executive is an employee of any Subsidiary of the Company, he shall be entitled to all of the rights and benefits of this Agreement as though he were an employee of the Company and the term “Company” shall be deemed to include the Subsidiary by whom the Executive is employed. The Company guarantees the performance of its Subsidiary under this Agreement.

15. Arbitration. The Company and the Executive shall attempt to resolve between them any dispute that arises under this Agreement.
