Such redemption distributions shall be made to the individual Redeeming OP Unit Holders in proportion to their respective Redemption Percentages.

(b) In connection with the Redemption, the Partnership shall provide Redeeming OP Unit Holders with the opportunity to guarantee the Redemption Core Property I Debt and/or Redemption Core Property II Debt, in an aggregate amount not less than the Required Debt, which guarantee opportunity shall be allocated among the Redeeming OP Unit Holders as determined by the Partnership.

The parties agree that the value of Redemption Core Property I has been allocated as set forth on Exhibit B hereto. The terms of the Redemption pursuant to this Section 2.02 shall not be affected by any change in the value of the Redemption OP Units or of the Redemption Core Properties, in each case, during the Interim Period.

(d) Except with respect to a Redeeming OP Unit Holder that has contributed property to the Partnership in exchange for Redemption OP Units in the seven years prior to the Redemption, the Company and the Partnership intend that, for U.S. federal and state income tax purposes, the Redemption will be treated as a non-taxable distribution of an undivided interest in

Indebtedness shall not be Qualifying Debt if and when there is another guarantee (other than a guarantee by a Redeeming OP Unit Holder) of the same portion of such indebtedness guaranteed by the Redeeming OP Unit Holder, except that TZ OP shall be permitted to enter into a guarantee of any such debt so long as in connection with such guarantee, TZ OP offers to the Redeeming OP Unit Holders the opportunity to indemnify and hold TZ OP harmless with respect to TZ OP’s guarantee in an amount and on the terms of the Redeeming OP Unit Holder’s direct liability to the lender under the terms of the Redeeming OP Unit Holder’s guarantee.

Notwithstanding the foregoing, at any time prior to receipt of the Company Stockholder Approval, the Company Board may take one of the actions described in clauses (i) or (ii) of the previous sentence in response to a Superior Proposal if the Company Board determines in good faith, after consultation with outside legal counsel, that failure to take such action would be reasonably likely to be inconsistent with the duties of the directors of the Company to the Company or its stockholder under applicable law (a

“Subsequent Determination”) but only at a time that is seventy-two (72) hours after Parent’s receipt of written notice from the Company that the Company Board is prepared to approve or recommend such Superior Proposal, or the applicable amendment to a Superior Proposal, and subject to the Company’s compliance, in all material respects, with this Section 8.04(b). Any such written notice shall specify the material terms and conditions of such Superior Proposal, identify the person making such Superior Proposal and state that the Board otherwise intends to make a Subsequent Determination (subject to compliance, in all material respects, with this Section 8.04(b)). During such seventy-two (72) hour period, the Company shall permit the Parent to propose to the Company’s Board adjustments to the terms and conditions of this Agreement with a view to enabling the Company to proceed with its recommendation to its stockholder without a Subsequent Determination.

(c) Upon execution of this Agreement, the Company and its Subsidiaries shall cease immediately and cause to be terminated any and all existing activities, discussions or negotiations with any parties conducted heretofore with respect to an Acquisition Proposal by or on behalf of the Company or any of the Company Representatives and shall inform each of the Company Representatives of its obligations under this Section 8.04 and instruct each of them to act in a manner consistent with such obligations. The Company shall promptly request each Person with whom it has executed a confidentiality agreement within the twelve months prior to the date hereof in connection with its consideration of any Acquisition Proposal to return or destroy all confidential or other non-public information heretofore furnished to such Person by or on behalf of the Company or any of the Company Representatives.

(d) Subject to the Company’s compliance, in all material respects, with Section 8.04(b), the Company may at any time take and disclose to its holders of Company Common Shares a position contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act or make any disclosure required by Rule 14a-9 promulgated under the Exchange Act or Item 1012(a) of Regulation M-A.

SECTION 8.05. Further Action; Reasonable Best Efforts.

(a) Upon the terms and subject to the conditions hereof, each of the parties hereto shall (i) make promptly its respective filings, and thereafter make any other required submissions, under the HSR Act with respect to the Mergers and (ii) use its reasonable best efforts to take, or cause to be taken, all appropriate action, and to do, or cause to be done, all things necessary, proper or advisable under applicable Laws or pursuant to any contract, agreement, lease or ground lease to consummate and make effective the Mergers, the Exchange, the Redemption and the Asset Sale, including, without limitation, using its reasonable best efforts to obtain all Permits, consents, approvals, authorizations, qualifications and orders of Governmental Authorities and parties to contracts, agreements, leases or ground leases with the Company and the Subsidiaries as are necessary for the consummation of the Mergers, the Exchange, the Redemption and the Asset Sale and to fulfill the conditions to the Closing. In case, at any time after the Closing, any further action is necessary or desirable to carry out the purposes of this Agreement, each of the parties hereto shall use all reasonable efforts to cause its respective officers, employees and agents to take all such action.

(b) The parties hereto shall cooperate and assist one another in connection with all actions to be taken pursuant to Section 8.05(a), including the preparation and making of the filings referred to therein and, if requested, amending or furnishing additional information thereunder, including, subject to applicable Laws and the Confidentiality Agreement, providing copies of all related documents to the non-filing party and their advisors prior to filing, and to the extent practicable none of the parties will file any such document or have any communication with any Governmental Authority without prior consultation with the other parties. Each party shall keep the others apprised of the content and status of any communications with, and communications from, any Governmental Authority with respect to the Mergers and the Asset Sale. To the extent practicable, and permitted by a Governmental Authority, each party hereto shall permit representatives of the other party to participate in meetings (whether by telephone or in person) with such Governmental Authority.

(c) Notwithstanding anything to the contrary contained in this Agreement, in connection with any filing or submission required or action to be taken by either Parent or the Company to consummate the Mergers or the Asset Sale, in no event shall Parent or any of its subsidiaries or Affiliates be obligated to propose or agree to accept any undertaking or condition, to enter into any consent decree, to make any divestiture or accept any operational restriction, or take or commit to take any action that, in the sole discretion of Parent, could be expected to limit (i) the freedom of action of Parent or its subsidiaries or Affiliates with respect to the operation of, or Parent’s or its subsidiaries’ or Affiliates’ ability to retain, the Company or any businesses, product lines or assets of the Company, or (ii) the ability of Parent to retain, own or operate any portion of the businesses, product lines, or assets, of Parent or any of its subsidiaries or Affiliates, or alter or restrict in any way the business or commercial practices of the Company, Parent or its subsidiaries or Affiliates. Parent and the Company shall promptly inform the other of any material communication from the United States Federal Trade Commission, the Department of Justice or any other Governmental Authority regarding the Mergers or the Asset Sale. If any such party or any Affiliate thereof receives a request for additional information or documentary material from any such Governmental Authority with respect to the Mergers or the Asset Sale, then such party will endeavor in good faith to make, or cause to be made, as soon as possible and after consultation with the other parties, an appropriate response in compliance with such request.

SECTION 8.06. Public Announcements.

The parties agree that no public release or announcement concerning the Exchange, the Redemption, the Asset Sale or the Mergers shall be issued by any party without the prior consent of the other parties (which consent shall not be unreasonably withheld or delayed), except as such release or announcement may be required by Law or the rules or regulations of any securities exchange, in which case the party required to make the release or announcement shall use its best efforts to allow the other parties reasonable time to comment on such release or announcement in advance of such issuance.

SECTION 8.07. Indemnification.

(a) Without limiting any additional rights that any employee, officer, director or other fiduciary may have under any employment or indemnification agreement or under the

Company Charter, the Company Bylaws, the Partnership Agreement or this Agreement or, if applicable, similar organization documents or agreements of any of the Subsidiaries, from and after the Effective Time, Parent, the Surviving Entity and the Surviving Partnership shall (i) indemnify and hold harmless each person who is now, has been at any time prior to the date hereof, or is or becomes during the period from the date hereof through the Effective Time serving as a director or executive officer of the Company, the Partnership or their Subsidiaries or a fiduciary under or with respect to any employee benefit plan (within the meaning of Section 3(3) of ERISA) sponsored by the Company or any of its Subsidiaries (collectively, the “Arden Indemnified Parties”) to the fullest extent authorized or permitted by applicable law, as now or hereafter in effect, in connection with any Claim and any judgments, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such judgments, fines, penalties or amounts paid in settlement) resulting therefrom; and (ii) promptly pay on behalf of or, within 30 days after any request for advancement, advance to each of the Arden Indemnified Parties, to the fullest extent authorized or permitted by applicable law, as now or hereafter in effect, any Expenses incurred in defending or serving as a witness with respect to any Claim in advance of the final disposition of such Claim, including payment on behalf of or advancement to the Arden Indemnified Party of any Expenses incurred by such Arden Indemnified Party in connection with enforcing any rights with respect to such indemnification and/or advancement, in each case without the requirement of any bond or other security. The indemnification and advancement obligations pursuant to this Section 8.07(a) shall extend to acts or omissions occurring at or before the Effective Time and any Claim relating thereto (including with respect to any acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby, including the consideration and approval thereof and the process undertaken in connection therewith and any Claim relating thereto), and all rights to indemnification and advancement conferred hereunder shall continue as to a person who has ceased to be a director, executive officer or other fiduciary of the Company, the Partnership or their Subsidiaries after the date hereof and shall inure to the benefit of such person’s heirs, executors and personal and legal representatives. As used in this Section 8.07(a), (i) the term “Claim” means any threatened, asserted, pending or completed Action, suit or proceeding, or any inquiry or investigation of any Governmental Authority or any other party, that any Arden Indemnified Party in good faith believes might lead to the institution of any such Action, suit or proceeding, whether civil, criminal, administrative, investigative or other, including any arbitration or other alternative dispute resolution mechanism, arising out of or pertaining to matters that relate to such Arden Indemnified Party’s duties or service as a director or executive officer of the Company, the Partnership, any of their Subsidiaries, or a fiduciary under any employee benefit plan (within the meaning of Section 3(3) of ERISA) sponsored by the Company, and (ii) the term “Expenses” means reasonable attorneys’ fees and all other reasonable costs, expenses and obligations (including, without limitation, experts’ fees, travel expenses, court costs, retainers, transcript fees, duplicating, printing and binding costs, as well as telecommunications, postage and courier charges) paid or incurred in connection with investigating, defending, being a witness in (including on appeal), or preparing to investigate, defend or be a witness in any Claim for which indemnification is authorized pursuant to this Section 8.07(a), including any Action relating to a claim for indemnification or advancement brought by a Arden Indemnified Party. Neither Parent, the Surviving Entity nor the Surviving Partnership shall settle, compromise or consent to the entry of any judgment in any actual or

threatened claim, demand, Action, suit, proceeding, inquiry or investigation in respect of which indemnification has been or could be sought by such Arden Indemnified Party hereunder unless such settlement, compromise or judgment includes an unconditional release of such Arden Indemnified Party from all liability arising out of such claim, demand, Action, suit, proceeding, inquiry or investigation or such Arden Indemnified Party otherwise consents thereto. No Arden Indemnified Party shall settle, compromise or consent to the entry of any judgment in any actual or threatened claim, demand, Action, suit, proceeding, inquiry or investigation in respect of which indemnification has been or could be sought by such Arden Indemnified Party without the consent of the Parent. The Surviving Entity and the Surviving Partnership shall have the right to defend each Arden Indemnified Party in any Action which may give rise to the payment of indemnification hereunder; provided, however, that the Surviving Entity or the Surviving Partnership shall notify such Arden Indemnified Party of any such decision to defend within ten (10) calendar days of receipt of notice of any such Action. Notwithstanding the preceding sentence, if in an Action to which an Arden Indemnified Party is a party and which is indemnifiable hereunder, (I) such Arden Indemnified Party reasonably concludes that he or she may have separate defenses or counterclaims to assert with respect to any issue which may not be consistent with the position of other defendants in such Action, (II) a conflict of interest or potential conflict of interest exists between such Arden Indemnified Party and the Surviving Entity or the Surviving Partnership, or (III) if the Surviving Entity or the Surviving Partnership fails to assume the defense of such Action in a timely manner, such Indemnified Party shall be entitled to be represented by separate legal counsel of such Indemnified Party’s choice at the expense of the Surviving Entity and the Surviving Partnership.

(b) Without limiting the foregoing, Parent and REIT Merger Sub agree that all rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time and Partnership Merger Effective Time, as applicable, now existing in favor of the current or former directors, officers, employees or other agents or fiduciaries of the Company, the Partnership or any of their Subsidiaries as provided in the Company Charter, Company Bylaws and Partnership Agreement (or, as applicable, the charter, bylaws, partnership agreement or other organizational documents of any of the Subsidiaries) and indemnification agreements of the Company, the Partnership or any of their Subsidiaries identified in Section 8.07(b) of the Disclosure Schedule shall be assumed by the Surviving Entity and the Surviving Partnership in the Mergers, without further action, at the Effective Time and Partnership Merger Effective Time, as applicable, survive the Mergers and shall continue in full force and effect in accordance with their terms.

(c) The Surviving Entity and the Surviving Partnership shall for a period of six years after the Effective Time cause to be maintained in effect in the Surviving Charter, Surviving Bylaws and Surviving Partnership Agreement (or similar governing documents), provisions regarding elimination of liability of directors, indemnification of officers and directors and advancement of expenses that are no less advantageous to the intended beneficiaries as those currently contained in the Company Charter, Company Bylaws and Partnership Agreement.

(d) The Surviving Entity and the Surviving Partnership shall maintain for a period of at least six years the current policies of directors’ and officers’ liability insurance maintained by the Company and its Subsidiaries with respect to claims arising from facts or events that occurred on or before the Effective Time, including, without limitation, in respect of

the transactions contemplated by this Agreement; provided that (i) the Surviving Entity may substitute therefor policies of at least the same coverage and amounts containing terms and conditions which are, in the aggregate, no less advantageous to the insured, provided that such substitution shall not result in gaps or lapses of coverage with respect to matters occurring before the Effective Time; (ii) in no event shall the Surviving Entity or the Surviving Partnership be required to expend, pursuant to the provisions of this Section 8.07(d), more than an amount per year of coverage equal to two hundred percent (200%) of current annual premiums, and (iii) the provisions of this Section 8.07(d) shall be deemed to have been satisfied if prepaid policies have been obtained by the Surviving Entity for purposes of this Section 8.07, which policies (together with the Company’s existing policy) provide such directors and officers with the coverage described in this Section 8.07(d) for an aggregate period of not less than six years with respect to claims arising from facts or events that occurred on or before the Effective Time, including, without limitation, in respect of the transactions contemplated by this Agreement. In the event that but for clause (ii) of the proviso in the preceding sentence, the Company would be required to expend more than two hundred percent (200%) of the current annual premiums, the Company shall obtain the maximum amount of such insurance obtainable by payment of annual premiums equal to two hundred percent (200%) of current annual premiums.

(e) If either the Surviving Entity or the Surviving Partnership or any of their respective successors or assigns (i) consolidates with or merges with or into any other person and shall not be the continuing or surviving corporation, partnership or other entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Entity or the Surviving Partnership assume the obligations of the Surviving Entity, or the Surviving Partnership, as the case may be set forth in this Section 8.07. The Company and Parent acknowledge and agree that Parent guarantees the payment and performance of the Surviving Entity’s and the Surviving Partnership’s obligations pursuant to this Section 8.07.

(f) The provisions of this Section 8.07 shall not be terminated or modified in such a manner as to adversely affect any indemnitee to whom this Section 8.07 applies without the consent of such affected indemnitee and are intended to be for the benefit of, and will be enforceable by, each indemnified party, his or her heirs and his or her legal representatives.

SECTION 8.08. Employee Benefit Matters.

(a) Parent shall, or shall cause the Surviving Entity to, continue to provide immediately following the Effective Time benefits under the Plans which are “employee benefit plans” as defined in Section 3(3) of ERISA which cover employees of the Company and each Subsidiary generally and which are in effect at the Effective Time as well as the Plans (other than equity compensation plans) which are in effect at the Effective Time and which cover employees of the Company and each Subsidiary generally (collectively, the “Company Plans”) to the employees of the Surviving Entity at the Effective Time (the “Company Employees”) or Parent shall, or shall cause the Surviving Entity to, provide benefits under plans which provide benefits which are comparable in the aggregate to the benefits provided under the Company Plans (collectively, the “Parent Benefit Plans”). If any Company Employees participate in any Parent Benefit Plans following the Effective Time, Parent shall, or shall cause the Surviving

Entity to, (i) recognize all service of the Company Employees with the Company or a Subsidiary, as the case may be, for purposes of vacation and severance and participation in, but not for purposes of benefit accrual, in any such Parent Benefit Plan to the extent such services were recognized under any corresponding Company Plan, (ii) waive all limitations as to preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the Company Employees under any Parent Benefit Plans which are welfare benefit plans that such employees may be eligible to participate in after the Effective Time, other than limitations or waiting periods that are already in effect with respect to such employees and that have not been satisfied as of the Effective Time under the corresponding Company Benefit Plan and (iii) provide each Company Employee with credit for any co-payments and deductibles paid prior to the Effective Time under any Company Benefit Plans in satisfying any applicable deductible or out-of-pocket requirements under any corresponding Parent Benefit Plan in which such employees are eligible to participate in immediately following the Effective Time.

(b) From and after the Effective Time, Parent shall cause the Surviving Entity to assume and honor in accordance with their terms all employment, severance and termination plans and agreements (including change-in-control provisions) of employees or independent contractors of the Company and the Subsidiaries listed in Section 4.09(a) of the Disclosure Schedule.

(d) Prior to the Effective Time, the Company Board, or an appropriate committee of non-employee directors thereof, shall adopt a resolution consistent with the interpretive guidance of the SEC so that the disposition by any officer or director of the Company who is a covered person of the Company for purposes of Section 16 of the Exchange Act and the rules and regulations thereunder (“ Section 16”) of Company Common Shares or Company Share Options pursuant to this Agreement and the Mergers shall be an exempt transaction for purposes of Section 16.

SECTION 8.09. Transfer Taxes.

Parent and the Company shall cooperate in the preparation, execution and filing of all returns, questionnaires, applications or other documents regarding any real property transfer or gains, sales, use, transfer, value added, stock transfer or stamp taxes, any transfer, recording, registration and other fees and any similar taxes that become payable in connection with the transactions contemplated by this Agreement (together with any related interests, penalties or additions to Tax, “Transfer Taxes”), and shall cooperate in attempting to minimize the amount of Transfer Taxes. From and after the Effective Time, the Surviving Entity shall pay or cause to be paid all Transfer Taxes, without deduction or withholding from any consideration or amounts payable to holders of the Company Common Shares, Existing Units and/or Company Share Options.

SECTION 8.10. Form of Election.

(a) As promptly as reasonably practicable following the date of this Agreement, the Company shall prepare a form of election in form and substance reasonably acceptable to the TZ REIT and Parent (the “Form of Election”) pursuant to which each holder of Partnership Units will have the right to specify (i) the number, if any, of Partnership Units which it desires to have redeemed for Redemption Core Property LLC Interests pursuant to the Redemption and (ii) the number, if any, of Partnership Units which it desires to have exchanged for the right to receive the Partnership Merger Consideration.

(b) The Company shall mail Forms of Election to each holder of Partnership Units, together with any other materials that the Company and Parent determine to be necessary or prudent. An election to receive Redemption Core Property LLC Interests in the Redemption shall be effective only if a properly executed Form of Election is received by the Company or its designees prior to 5:00 p.m., Pacific Time, on the twentieth (20th) Business Day preceding the Company Stockholder Meeting or such shorter period as the parties shall agree. If a holder of Partnership Units fails to return a duly completed Form of Election within the time period specified above, such holder shall be deemed to have elected to convert each of such holder’s Partnership Units into the right to receive the Partnership Merger Consideration upon the conversion thereof in the Partnership Merger. TZ REIT, TZ OP, Parent and the Company by mutual agreement shall have the right to make rules, not inconsistent with the terms of this Agreement, governing the validity of Forms of Election and the issuance and delivery of the TZ Units, as applicable.

(c) TZ REIT, TZ OP, the Company and the Partnership shall each reasonably cooperate with each holder of Partnership Units who validly elects to receive Redemption Core Property LLC Interests to take all other reasonable and necessary steps so that such holders shall enjoy the full rights and benefits of the Redemption Core Property LLC Interests and shall subsequently become members of TZ OP.

the Company, the Partnership or any Subsidiary be obligated to become a party to the Purchase and Sale Agreement or to incur any liability thereunder, or pay costs or other monies in connection with the Asset Sale prior to the Closing, other than as provided in Section 8.03(b), (iii) in no event shall the Closing be extended as a result of or in connection with any Asset Sale, (iv) TZ REIT, TZ OP or any other purchaser under any Asset Sale agrees that it shall have no claim or cause of action against the Company, the Partnership or any Subsidiary prior to the Closing of the Mergers or in the event of termination of this Agreement, and (v) Parent agrees to indemnify, defend and hold harmless and protect the Company, the Partnership and any Subsidiary from any claim, expense, damage, liability and/or cause of action incurred or suffered by the Company, the Partnership or any Subsidiary in connection with or arising out of any Asset Sale.

(d) by the Company or Parent if the Company Stockholder Approval is not obtained at the Company Stockholder Meeting.

(e) by Parent if (i) an Adverse Recommendation Change shall have occurred; or (ii) the Company Board shall have caused the Company or the Partnership to enter into any Acquisition Agreement.

(f) by the Company, prior to obtaining the Company Stockholder Approval at the Company Stockholder Meeting, in order for the Company to enter into a definitive agreement for a Superior Proposal, provided that for such termination to be effective the Company shall have (i) complied with its obligations in all material respects under Section 8.04 and (ii) paid the Termination Fee required by Section 10.03.

(g) by Parent upon written notice from Parent to the Company, if the Company or the Partnership breaches or fails to perform in any material respect any of its representations, warranties or covenants contained in this Agreement, which breach or failure to perform would give rise to the failure of a condition set forth in Section 9.02(a) or 9.02(b) and such condition is not satisfied (or is incapable of being satisfied) by the Expiration Date.

(h) by the Company upon written notice from the Company to the Parent, if the Parent or REIT Merger Sub breaches or fails to perform in any material respect any of its representations, warranties or covenants contained in this Agreement, which breach or failure to perform would give rise to the failure of a condition set forth in Sections 9.03(a) or 9.03(b) and such condition is not satisfied (or is incapable of being satisfied) by the Expiration Date.

SECTION 10.02. Effect of Termination.

In the event of termination of this Agreement and abandonment of the Mergers and the other transactions contemplated by this Agreement pursuant to and in accordance with Section 10.01, this Agreement shall forthwith become void and of no further force or effect whatsoever and there shall be no liability on the part of any party, or their respective officers, directors, subsidiaries or partners, as applicable, to this Agreement; provided, however, that nothing contained in this Agreement shall relieve any party to this Agreement from any liability resulting from or arising out of any breach of any agreement or covenant hereunder; provided, further, that notwithstanding the foregoing, the covenants and other obligations under this Agreement shall terminate upon the termination of this Agreement, except that the agreements set forth in Section 8.03(c), Section 8.03(d), Section 8.06, Section 10.03, Section 11.08 and Section 11.09 shall survive termination indefinitely. If this Agreement is terminated as provided herein, all filings, applications and other submissions made pursuant to this Agreement, to the extent practicable, shall be withdrawn from the agency or other person to which they were made.

SECTION 10.03. Fees and Expenses.

(a) Except as otherwise explicitly set forth in this Section 10.03 or elsewhere in this Agreement, all costs and expenses incurred in connection with this Agreement, or the transactions contemplated hereby shall be paid by the party incurring such expenses, whether or not the transactions contemplated by this Agreement are consummated; provided, however, that (i) Parent shall pay any filing fees required in connection with filings under the HSR Act and (ii) the Company shall pay the expenses related to printing, filing and mailing the Proxy Statement (and any amendments or supplements thereto) and all SEC and other regulatory filing fees (if any) incurred in connection with the Proxy Statement.

(b) The Company agrees that if this Agreement shall be terminated:

(i) by Parent or the Company pursuant to Section 10.01(d), or by Parent pursuant to Section 10.01(e)(i), and (A) prior to the Termination Date, an Acquisition Proposal shall have been publicly announced that is not subsequently withdrawn prior to the Termination Date, and (B) (y) within nine (9) months following such termination the Company enters into an agreement with respect to an Acquisition Proposal; or (z) within one (1) year following the Termination Date an Acquisition Proposal is consummated, then the Company shall pay to Parent, when consummation of such Acquisition Proposal occurs, an amount equal to $100.0 million (the “Termination Fee”), less Parent Expenses previously paid, if any; or

(ii) by the Parent pursuant to Section 10.01(e)(ii) or by the Company pursuant to Section 10.01(f), then the Company shall pay the Termination Fee to Parent on the Termination Date if terminated pursuant to Section 10.01(f) or within three (3) days following the Termination Date if terminated pursuant to Section 10.01(e)(ii); or

(iii) by the Company or the Parent pursuant to Section 10.01(c) and (A) prior to the Termination Date an Acquisition Proposal shall have been publicly announced that is not subsequently withdrawn prior to the Termination Date and (B) (y) within nine (9) months following such termination the Company enters into an agreement with respect to an Acquisition Proposal; or (z) within one (1) year following such termination an Acquisition Proposal is consummated, then the Company shall pay to Parent the Termination Fee when consummation of the Acquisition Proposal occurs.

(c) If this Agreement is terminated by the Company pursuant to Section 10.01(h), Parent shall pay to the Company within three (3) Business Days after the date of termination all documented, reasonable out-of-pocket costs and expenses, including, without limitation, the reasonable fees and expenses of lawyers, accountants, consultants, financial advisors and investment bankers, incurred by the Company or its Subsidiaries in connection with the entering into of this Agreement and the carrying out of any and all acts contemplated hereunder up to an aggregate maximum amount of $10.0 million. If this Agreement is terminated by either the Company or Parent pursuant to Section 10.01(d) or by Parent pursuant to Section 10.01(g), the Company shall pay to Parent, within three (3) Business Days after the date of termination, all documented, reasonable out-of-pocket costs and expenses, including, without limitation, the reasonable fees and expenses of lawyers, accountants, consultants,

financial advisors, and investment bankers, incurred by Parent in connection with the entering into of this Agreement and the carrying out of any and all acts contemplated hereunder up to an aggregate maximum amount of $10.0 million (the “Parent Expenses”). The payment of expenses set forth in this Section 10.03(c) is not an exclusive remedy, but is in addition to any other rights or remedies available to the parties hereto (whether at law or in equity), and in no respect is intended by the parties hereto to constitute liquidated damages, or be viewed as an indicator of the damages payable, or in any other respect limit or restrict damages available in case of any breach of this Agreement.

(d) In the event that either Parent or the Company is required to file suit to seek all or a portion of the amounts payable under this Section 10.03, and such party prevails in such litigation, such party shall be entitled to all expenses, including attorneys’ fees and expenses, which it has incurred in enforcing its rights under this Section 10.03 .
