Subject to the terms and conditions of the Offer, Merger Sub shall (and Parent shall cause Merger Sub to), in accordance with the terms of the Offer, consummate the Offer and accept for payment and pay for all shares of Company Common Stock (the time of such first acceptance, the “Acceptance Time”) validly tendered and not properly withdrawn pursuant to the Offer promptly

after expiration of the Offer, which shall initially be the later of April 2, 2010 or the date that is fifteen (15) Business Days after the date of this Agreement; provided, however, that (w) if on the initial expiration date of the Offer or on any subsequent scheduled expiration date of the Offer (as it may be extended and re-extended in accordance with this Agreement), any of the events or conditions to the Offer set forth on Annex I shall exist and, subject to the provisions of this Agreement, shall not have been waived by Merger Sub, Merger Sub shall (and Parent shall cause Merger Sub to), from time to time, extend the Offer for consecutive periods of not more than five (5) Business Days each until the earlier of (A) the date on which all of the events or conditions set forth in Annex I cease to exist or, subject to the provisions of this Agreement, are waived by Merger Sub and (B) the date on which this Agreement is terminated in accordance with ARTICLE VIII; provided that Merger Sub shall have no obligation to (and Parent shall have no obligation to cause Merger Sub to) so extend the Offer if (1) the events or conditions set forth in subsections (ii), (iii) and (iv) of the first paragraph of Annex I and subparagraph (a) of Annex I shall have ceased to exist, or subject to the provisions of this Agreement, been waived by Merger Sub, for a period of not less than ten (10) Business Days prior to the initial expiration date of the Offer or on any subsequent scheduled expiration date of the Offer (as it may be extended and re-extended in accordance with this Agreement) and, with respect to subsections (ii), (iii) and (iv) of the first paragraph of Annex I, such facts shall be reflected in an amendment to the Offer Documents prior to the start of such ten (10) Business Day period, (2) the events or conditions set forth in subparagraphs (b), (c) and (d) of Annex I shall have ceased to exist or, subject to the provisions of this Agreement, been waived by Merger Sub, as of such expiration date and (3) the Minimum Condition is not satisfied as of such expiration date, (x) if on the initial expiration date of the Offer or on any subsequent scheduled expiration date of the Offer (as it may be extended and re-extended in accordance with this Agreement), the Company shall have delivered to Parent a valid Section 8.1(d) Notice, Merger Sub shall (and Parent shall cause Merger Sub to), from time to time, extend the Offer for consecutive periods of not more than five (5) Business Days each until the earlier of (A) the date on which all of the events or conditions set forth in the paragraph immediately following Section 8.1(d)(i) cease to exist or are waived by the Company and (B) the date on which this Agreement is terminated in accordance with ARTICLE VIII, (y) Merger Sub may, in its sole discretion, extend the Offer for any period required by any rule, regulation, interpretation or position of the SEC (or the staff thereof) or the NYSE applicable to the Offer and (z) Merger Sub may, in its sole discretion, provide a “subsequent offering period” in accordance with Rule 14d-11 under the Exchange Act; provided that, in the case of clauses (w), (x), (y) and (z), in no event shall the Offer extend beyond the Walk-Away Date. Merger Sub expressly reserves the right from time to time to waive any of the conditions set forth in Annex I (other than the Minimum Condition, the Registration Condition, the Listing Condition and the condition set forth in subparagraph (e) of Annex I) or to increase the Offer Price or to make any other changes in the terms and conditions of the Offer; provided that, without the prior written consent of the Company, Merger Sub shall not decrease the Offer Price, change the form of consideration payable in the Offer, decrease the number of shares of Company Common Stock sought to be purchased in the Offer, change, modify or waive the Minimum Condition, impose additional conditions to the Offer or modify or change any condition to the Offer in a manner materially adverse to the holders of shares of Company Common Stock or in a manner which would delay consummation of the Offer, reduce the time period during which the Offer shall remain open or, except for any extension required or permitted hereunder, extend or otherwise change the expiration date of the Offer, or amend, modify or

supplement any other term of the Offer in any manner adverse to the holders of shares of Company Common Stock or in a manner which would delay consummation of the Offer.

               (b) Subject to the first sentence of Section 2.1(a), as promptly as reasonably practicable and, in any event, within five (5) Business Days of the date of this Agreement, in order to reflect the execution of this Agreement and the terms hereof, Parent shall file or cause to be filed with the SEC (i) an amendment to Parent’s registration statement on Form S-4 (as it may be amended or supplemented, the “Form S-4”) and (ii) an amendment to Parent’s and Merger Sub’s tender offer statement on Schedule TO, as amended, each originally filed on March 5, 2010 with respect to the Pending Offer (such schedule together with the Form S-4, and the documents included therein pursuant to which the Offer is made, and any amendments and supplements thereto, the “Offer Documents”). Each Party shall use its best efforts (i) to have the Form S-4 declared effective under the Securities Act as promptly as reasonably practicable after such filing and (ii) to have removed as promptly as reasonably practicable any stop order suspending its effectiveness. Subject to the Company’s compliance with Section 2.2(c), Parent and Merger Sub shall cause the Offer Documents to be disseminated to holders of shares of Company Common Stock as required by applicable U.S. federal securities Laws.

Parent and Merger Sub further agree to take all steps necessary to cause the Offer Documents as so corrected to be filed with the SEC and disseminated to holders of shares of Company Common Stock as required by applicable U.S. federal securities Laws.

               (c) In the event this Agreement is terminated pursuant to Section 8.1 prior to the Acceptance Time, Parent and Merger Sub shall promptly terminate the Offer without accepting any shares of Company Common Stock previously tendered and Merger Sub shall promptly return, and shall cause any depository acting on behalf of Merger Sub to return, all tendered shares of Company Common Stock to the registered holders thereof.

               (d) No certificates or scrip representing fractional shares of Parent Common Stock shall be issued by virtue of the Offer, no dividends or other distributions of Parent shall relate to such fractional share interests and such fractional share interests shall not entitle the owner thereof to vote or to any rights of a stockholder of Parent. In lieu of such fractional share interests, Parent shall pay to each holder of shares of Company Common Stock who would otherwise be entitled to a fraction of a share of Parent Common Stock (after aggregating all fractional shares of Parent Common Stock that otherwise would be received by such holder) an

amount in cash equal to the product obtained by multiplying (i) the fractional share interest to which such holder would otherwise be entitled by (ii) the average closing sales price, rounded to four decimal points, of shares of Parent Common Stock on the NYSE (as reported in the Wall Street Journal, New York City edition) for the period of the ten (10) consecutive trading days ending on the second full trading day prior to the Acceptance Time (the “Parent Common Stock Cash Value”).

               (e) If any portion of the Offer Price is to be registered in the name of or paid to a Person other than the Person in whose name the tendered shares of Company Common Stock are registered, the amount of any stock transfer or other similar Taxes (whether imposed on the registered holder(s), or such other Person, or otherwise) payable on account of such issuance or transfer to such other Person shall be deducted from the Offer Price for the exchange of such shares of Company Common Stock in the Offer, unless evidence satisfactory to Merger Sub of the payment of such Taxes, or exemption therefrom, is submitted.

               (f) Parent shall provide or cause to be provided to Merger Sub on a timely basis the funds necessary to pay for any shares of Company Common Stock that Merger Sub becomes obligated to accept for payment, and pay for, pursuant to the Offer.

               (a) The Company hereby represents that its Board of Directors, at a meeting duly called and held has unanimously (i) determined that this Agreement and the transactions contemplated hereby, including the Offer and the Merger, are advisable to, and in the best interests of, the Company and its stockholders, (ii) approved this Agreement and approved the transactions contemplated hereby, including the Offer and the Merger, in accordance with the requirements of the MGCL (and such approval includes the approval of the Merger by the Board of Directors of the Company (or other required declaration or determination by the Board of Directors of the Company, as applicable) pursuant to both Section 3-105 of the MGCL and, if available, Section 3-106 of the MGCL), (iii) resolved to recommend that stockholders of the Company accept the Offer and tender their shares of Company Common Stock to Merger Sub in the Offer and, to the extent required by applicable Law, approve the Merger (the “Company Recommendation”) and (iv) taken all other actions necessary to exempt the Offer, the Merger, this Agreement and the transactions contemplated hereby from the restrictions imposed by the MGCL, including Title 3, Subtitle 6 and Title 3, Subtitle 7 of the MGCL, or any other “fair price,” “moratorium,” “control share acquisition” or similar anti-takeover statute, which exemption shall be irrevocable during the term of this Agreement. The Company consents to the inclusion of the Company Recommendation in the Offer Documents. The Company has been advised that all of its directors and executive officers who own shares of Company Common Stock intend to tender such shares pursuant to the Offer.

Recommendation; provided that the Company may file the Schedule 14D-9 (or an amendment thereto) at an earlier date if required by applicable Law. The Company agrees to cause the Schedule 14D-9 to be filed with the SEC and disseminated to holders of shares of Company Common Stock as required by and in accordance with applicable U.S. federal securities Laws and to use its reasonable best efforts to cause the Schedule 14D-9 to be distributed to such holders concurrently with the Offer Documents, as amended pursuant to Section 2.1(b). The Company, on the one hand, and Parent and Merger Sub, on the other hand, agree to promptly correct any information provided by it for use in the Schedule 14D-9 if it shall have become false or misleading in any material respect or as otherwise required by Law. The Company agrees to cause the Schedule 14D-9 as so corrected to be filed with the SEC and disseminated to holders of the shares of Company Common Stock as required by and in accordance with applicable U.S. federal securities Laws.

               (a) Upon the payment by Merger Sub for shares of Company Common Stock pursuant to the Offer representing at least such number of shares of Company Common Stock as shall satisfy the Minimum Condition, Parent shall be entitled to designate such number of new directors, rounded up to the next whole number, on the Board of Directors of the Company as is equal to the product of the total number of directors on the Board of Directors of the Company (determined after giving effect to the new directors elected pursuant to this sentence) multiplied by the percentage that the aggregate number of shares of Company Common Stock beneficially owned by Parent, Merger Sub and any of their Affiliates bears to the total number of shares of Company Common Stock then outstanding, and the Company shall promptly take all actions necessary to cause Parent’s designees to be so elected; provided, however, that prior to the Effective Time, the Board of Directors of the Company shall always have at least three members who were members of the Board of Directors of the Company as of immediately prior to the Acceptance Time and who are independent directors for purposes of the continued listing requirements of the NYSE (the “Company Directors”). If prior to the Effective Time, (i) the number of directors who are

Company Directors is reduced to two (2), the remaining directors who were Company Directors shall be entitled to designate one (1) person to the Board of Directors of the Company who is not an officer, director, employee or designee of Parent, Merger Sub or any of their Affiliates and who is reasonably satisfactory to Parent, (ii) the number of directors who are Company Directors is reduced to one (1), the remaining director who was a Company Director shall be entitled to designate two (2) persons to the Board of Directors of the Company who are not officers, directors, employees or designees of Parent, Merger Sub or any of their Affiliates and who are reasonably satisfactory to Parent and (iii) there shall be no Company Directors for any reason, then the remaining individuals who constituted the Company’s Board of Directors immediately prior to the Acceptance Time shall be entitled to designate three (3) persons to the Board of Directors of the Company who are not officers, directors, employees or designees of Parent, Merger Sub or any of their Affiliates and who are reasonably satisfactory to Parent (and, in each case, the persons so designated shall be considered Company Directors for purposes of this Agreement).

The Company’s obligations to cause the election or appointment of Parent’s designees to the Board of Directors of the Company shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 thereunder. The Company shall promptly take all actions required pursuant to Section 14(f) of the Exchange Act and Rule 14f-1 thereunder in order to fulfill its obligations under this Section 2.3(a), and shall include in the Schedule 14D-9 such information with respect to the Company and its officers and directors as is required under Section 14(f) of the Exchange Act and Rule 14f-1 thereunder in order to fulfill its obligations under this Section 2.3(a), so long as Parent shall have provided to the Company on a timely basis the information and consents with respect to Parent and its nominees, officers, directors and Affiliates required by Section 14(f) of the Exchange Act and Rule 14f-1 thereunder.

The Company shall deliver to Parent true and complete copies of such resignations prior to the Acceptance Time.

               (c) Notwithstanding anything in this Agreement to the contrary but subject to Section 9.8, following the time directors designated by Parent are elected or appointed to the Board of Directors of the Company and prior to the Effective Time, the affirmative vote of a majority of the Company Directors then in office shall be required to (i) amend or terminate this Agreement on behalf of the Company, (ii) exercise or waive any of the Company’s rights or remedies hereunder, (iii) agree to extend the time for performance of Parent’s or Merger Sub’s obligations hereunder, or (iv) take any other action by the Company in connection with this Agreement and the transactions contemplated hereby required to be taken by the Board of Directors

of the Company adversely affecting the rights of the Company’s stockholders (other than Parent or Merger Sub).

          Section 2.4 Top-Up Option.

               (a) The Company hereby grants to Parent and/or Merger Sub an irrevocable option (the “Top-Up Option”), subject to the terms and conditions hereof, to purchase that number of shares of Company Common Stock (the “Top-Up Shares”) equal to the lowest number of shares of Company Common Stock that, when added to the number of shares of Company Common Stock owned by Merger Sub at the time of such exercise, shall constitute one share of Company Common Stock more than ninety percent (90%) of the number of shares of Company Common Stock entitled to vote on the Merger after the issuance of the Top-Up Shares, calculated on a fully-diluted basis, or, at Parent’s election, on a primary basis, at an exercise price per Top-Up Share equal to the Offer Price (with, for this purpose only, the value of the fraction of the share of Parent Common Stock included in the Offer Price fixed at $10.25); provided, however, that the Top-Up Option may be exercised only if (i) the issuance of the Top-Up Shares shall not require approval of the Company’s stockholders under applicable Law (including the rules of the NYSE), (ii) the exercise of the Top-Up Option and the issuance and delivery of the Top-Up Shares shall not be prohibited by any Law or Order and (iii) the Top-Up Option is exercisable for not more than the number of shares of Company Common Stock in excess of the shares of Company Common Stock authorized but unissued (and not reserved for issuance) at the time of exercise of the Top-Up Option.

               (b) The Top-Up Option shall only be exercisable once in whole and not in part at any time within ten (10) Business Days following the payment by Merger Sub for shares of Company Common Stock pursuant to the Offer representing at least such number of shares of Company Common Stock as shall satisfy the Minimum Condition, or if any subsequent offering period is provided, during the ten (10) Business Day period following the expiration date of the subsequent offering period; provided, however, that the Top-Up Option shall terminate upon the earlier of (i) the termination of this Agreement in accordance with the terms hereof and (ii) the Effective Time.

               (c) In the event Parent or Merger Sub wishes to exercise the Top-Up Option, Parent or Merger Sub shall so notify the Company in writing at least three (3) Business Days in advance of such exercise and shall set forth in such notice (i) whether Parent is electing to have the number of Top-Up Shares determined on a fully-diluted or primary basis, (ii) the number of shares of Company Common Stock owned by Merger Sub immediately preceding the purchase of the Top-Up Shares and (iii) the place and time for the closing of the purchase of the Top-Up Shares (the “Top-Up Closing”). The Company shall, as soon as practicable following receipt of such notice, notify Parent and Merger Sub in writing of the number of shares of Company Common Stock then outstanding and, based on the information specified in the notice of Parent or Merger Sub, the number of Top-Up Shares. At the Top-Up Closing, (i) Parent or Merger Sub shall pay to the Company the aggregate price required to be paid for the Top-Up Shares, at the election of Parent and Merger Sub, in cash or by delivery of a promissory note which shall have the following terms: it shall be due on the first anniversary of the Top-Up Closing; it shall bear simple interest of five percent (5%) per annum; it shall have full recourse to Parent; and it shall have no other

material terms and (ii) the Company shall cause to be issued to Merger Sub a certificate representing the Top-Up Shares.

               (d) Parent and Merger Sub acknowledge that the Top-Up Shares will not be registered under the Securities Act and will be issued in reliance upon an exemption thereunder for transactions not involving a public offering. Each of Parent and Merger Sub hereby represents and warrants to the Company that each of Parent and Merger Sub is, and will be upon the purchase of the Top-Up Shares, an “accredited investor,” as such term is defined in Rule 501 of Regulation D under the Securities Act. Parent and Merger Sub agree that the Top-Up Option and the Top-Up Shares to be acquired upon exercise of the Top-Up Option are being and will be acquired by Parent or Merger Sub for the purpose of investment and not with a view to, or for resale in connection with, any distribution thereof (within the meaning of the Securities Act).

          Section 2.5 Short Form Merger. Notwithstanding anything to the contrary in this Agreement, if, after the consummation of the Offer and any exercise of the Top-Up Option, the shares of Company Common Stock beneficially owned by Merger Sub represent at least ninety percent (90%) of the then-outstanding shares of Company Common Stock, Parent shall cause Merger Sub to, and the Company shall, execute and deliver such documents and instruments and take such other actions as Parent or Merger Sub may reasonably request, in order to cause the Merger to be completed as promptly as reasonably practicable as provided in Section 3-106 of the MGCL, and otherwise as provided in this ARTICLE II.

          Section 2.8 Effective Time. Subject to the provisions of this Agreement, on the Closing Date, Merger Sub and the Company shall file articles of merger (“Articles of Merger”)

As used herein, the “Effective Time” shall mean the time at which the Merger shall become effective.

          Section 2.9 Surviving Corporation Constituent Documents.

The Board of Directors of the Company (or the relevant committee thereof responsible for administration of the Company Stock Plans) has adopted or shall adopt prior to the Acceptance Time resolutions, and the Company has taken or shall take prior to the Acceptance Time all actions (including obtaining consent from any applicable holder), necessary to ensure that, as of the Acceptance Time, each Equity Right consisting of, based on or relating to shares of Company Common Stock granted under any equity or equity-based compensation plan or arrangement of the Company (each, a “Company Stock Plan”) (each, a “Company Stock-Based Award”) which is outstanding immediately prior to the Acceptance Time shall be treated as set forth below:

               (a) each Company Restricted Share shall become fully vested immediately prior to the Acceptance Time pursuant to its terms and without any action on the part of any holder thereof;

               (b) each Company Phantom Unit shall be fully vested at the Acceptance Time and the holder thereof shall be entitled to receive, in consideration therefor, a cash payment from the Company equal to the product of (A) the number of shares of Company Common Stock subject to such Company Phantom Unit immediately prior to the Acceptance Time and (B) the Cash Equivalent Amount, which cash payment shall be delivered by the Company to such holder as promptly as practicable following the Acceptance Time (but in any event within the period required by Section 409A of the Code, such that it qualifies as a “short-term deferral” pursuant to Section 1.409A-1(b)(4) of the Treasury Regulations); and

               (c) each Company Performance Share Award and each Company Phantom Performance Award shall be canceled at the Acceptance Time and the holder thereof shall be entitled to receive, in consideration for such cancellation, the product of (A) the greater of (1) the number of shares of Company Common Stock subject to such Company Performance Share Award or Company Phantom Performance Award based on the Company’s actual performance calculated using actual quarters completed through the Acceptance Time and (2) the target number of shares of Company Common Stock subject to such Company Performance Share Award or Company Phantom Performance Award and (B) the Cash Equivalent Amount, which cash payment shall be delivered by the Company to such holder as promptly as practicable following the Acceptance Time (but in any event within the period required by Section 409A of the Code, such that it qualifies as a “short-term deferral” pursuant to Section 1.409A-1(b)(4) of the Treasury Regulations).

          For purposes of this Section 2.12, the term “Cash Equivalent Amount” shall mean an amount equal to the sum of (A) the cash portion of the Offer Price and (B) the product of (1) the Parent Common Stock Cash Value and (2) the portion of the Offer Price paid in shares of Parent Common Stock.

          Section 2.13 Appraisal or Dissenters’ Rights. No appraisal or dissenters’ rights shall be available to holders of shares of Company Common Stock with respect to the Merger or the other transactions contemplated hereby, provided that, if the Merger is not effected under Section 3-106 of the MGCL, the Company Common Stock is listed on the NYSE on the record date for determining the stockholders entitled to vote on the Merger.

          Section 2.14 Exchange of Shares.

               (a) Prior to the Effective Time, Parent shall appoint an exchange agent reasonably satisfactory to the Company (the “Exchange Agent”) for the purpose of exchanging Certificates for the Merger Consideration. As soon as reasonably practicable after the Effective Time, Parent will cause the Exchange Agent to send to each holder of record of shares of Company Common Stock as of the Effective Time whose shares of Company Common Stock were converted into the right to receive the Merger Consideration pursuant to Section 2.11, a letter of transmittal (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates to the Exchange Agent), including instructions for use in effecting the surrender of Certificates to the Exchange Agent in exchange for the Merger Consideration. Immediately after the Effective Time, Parent shall cause to be deposited with the Exchange Agent (i) the number of duly authorized, fully paid and nonassessable shares of Parent Common Stock (which shall be in non-certificated book-entry form) payable as Merger Consideration upon due surrender of the Certificates pursuant to the provisions of this ARTICLE II and (ii) cash in U.S. dollars sufficient to pay the aggregate cash portion of the Merger Consideration payable upon due surrender of the Certificates pursuant to the provisions of this ARTICLE II, in each case in trust for each holder of shares of Company Common Stock. Following the Effective Time, Parent agrees to make available to the Exchange Agent, from time to time as needed, cash in U.S. dollars sufficient to pay any dividends and other distributions pursuant to Section 2.14(f). All cash and book-entry shares representing Parent Common Stock deposited with the Exchange Agent shall be referred to in this Agreement as the “Exchange Fund.” The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration contemplated to be issued and paid pursuant to Section 2.11 and Section 2.14(g) out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose. The Exchange Agent shall invest the cash included in the Exchange Fund as directed by Parent. Any interest and other income resulting from such investments shall be the property of, and paid to, Parent.

               (b) Each holder of shares of Company Common Stock that have been converted into the right to receive the Merger Consideration, upon surrender to the Exchange Agent of a Certificate, together with a properly completed letter of transmittal, duly executed and completed in accordance with the instructions thereto, and such other documents as may reasonably be required by Parent or the Exchange Agent, will be entitled to receive in exchange therefor (i) one or more duly authorized, fully paid and nonassessable shares of Parent Common Stock (which shall be in non-certificated book-entry form unless a physical certificate is requested) representing, in the aggregate, the whole number of shares of Parent Common Stock that such holder has the

right to receive, (ii) a check drawn by the Exchange Agent or a bank cashier’s check in the amount that such holder has the right to receive pursuant to the provisions of this ARTICLE II, including the cash portion of the Merger Consideration and dividends and other distributions payable pursuant to Section 2.14(f). The Merger Consideration shall be paid as promptly as practicable after receipt by the Exchange Agent of the Certificate and letter of transmittal in accordance with the foregoing. No interest shall be paid or accrued on any Merger Consideration or on any unpaid dividends and distributions payable to holders of Certificates. Until so surrendered, each such Certificate shall, after the Effective Time, represent for all purposes only the right to receive such Merger Consideration.

               (c) If any portion of the Merger Consideration is to be registered in the name of or paid to a Person other than the Person in whose name the applicable surrendered Certificate is registered, it shall be a condition thereof that the surrendered Certificate shall be properly endorsed or otherwise be in proper form for transfer and that the Person requesting such delivery of the Merger Consideration shall pay to the Exchange Agent any required transfer or other similar Taxes or establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

               (d) After the Effective Time, there shall be no further registration of transfers of shares of Company Common Stock outstanding immediately prior to the Effective Time. From and after the Effective Time, the holders of Certificates representing shares of Company Common Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares of Company Common Stock except as otherwise provided in this Agreement or by applicable Law. If, after the Effective Time, Certificates are presented to the Exchange Agent or Parent, they shall be cancelled and exchanged for the consideration provided for, and in accordance with the procedures set forth, in this ARTICLE II.

               (e) Any portion of the Exchange Fund that remains unclaimed by the holders of shares of Company Common Stock one (1) year after the Effective Time shall be returned to Parent, upon demand, and any such holder who has not exchanged his or her shares of Company Common Stock for the Merger Consideration in accordance with this Section 2.14 prior to that time shall thereafter look only to Parent for delivery of the Merger Consideration in respect of such holder’s shares of Company Common Stock. Notwithstanding the foregoing, none of Parent, Merger Sub or the Company shall be liable to any holder of shares of Company Common Stock for any Merger Consideration delivered to a public official pursuant to applicable abandoned property Laws. Any Merger Consideration remaining unclaimed by holders of shares of Company Common Stock immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Entity shall, to the extent permitted by applicable Law, become the property of Parent free and clear of any claims or interest of any Person previously entitled thereto.

               (f) No dividends or other distributions with respect to shares of Parent Common Stock issued in the Merger shall be paid to the holder of any unsurrendered Certificates until such Certificates are surrendered as provided in this Section 2.14. Following such surrender, subject to the effect of escheat, Tax or other applicable Law, there shall be paid, without interest, to the record holder of the shares of Parent Common Stock issued in exchange therefor (i) at the time of such surrender, all dividends and other distributions payable in respect of such shares of Parent

Common Stock with a record date after the Effective Time and a payment date on or prior to the date of such surrender and not previously paid and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such shares of Parent Common Stock with a record date after the Effective Time but with a payment date subsequent to such surrender. For purposes of dividends or other distributions in respect of shares of Parent Common Stock, all shares of Parent Common Stock to be issued pursuant to the Merger shall be entitled to dividends pursuant to the immediately-preceding sentence as if issued and outstanding as of the Effective Time.

               (g) No certificates or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Certificates to the Exchange Agent for the Merger Consideration, no dividends or other distributions of Parent shall relate to such fractional share interests and such fractional share interests shall not entitle the owner thereof to vote or to any rights of a stockholder of Parent. In lieu of such fractional share interests, Parent shall pay to each holder of a Certificate an amount in cash equal to the product obtained by multiplying (i) the fractional share interest to which such holder (after taking into account all shares of Company Common Stock formerly represented by all Certificates surrendered by such holder) would otherwise be entitled by (ii) the Parent Common Stock Cash Value.

               (h) If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person of a bond, in such reasonable amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration to be paid in respect of the shares of Company Common Stock represented by such Certificate as contemplated by this ARTICLE II.

          Section 2.15 Withholding Rights. Each of Parent, Merger Sub and the Surviving Corporation shall be entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from the consideration otherwise payable to any Person pursuant to this Agreement (including pursuant to Section 2.12) such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax Law. To the extent that amounts are so deducted or withheld and paid over to the applicable Governmental Entity or Taxing Authority, such deducted or withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of Company Common Stock or any Company Stock-Based Award in respect of which such deduction and withholding was made.

          Section 2.16 Certain Adjustments. If at any time during the period between the date of this Agreement and the Effective Time, any change in the outstanding shares of Securities of Parent or the Company shall occur by reason of any reclassification, recapitalization, stock split or combination, exchange or readjustment of shares, or any stock dividend thereon with a record date during such period, the Offer Price, the Merger Consideration and any other similarly dependent items shall be appropriately adjusted to provide the holders of shares of Company Common Stock the same economic effect as contemplated by this Agreement prior to such event. Nothing in this Section 2.16 shall be construed to require or permit the Company or Parent to take any action that is otherwise prohibited or restricted by any other provision of this Agreement.

          Section 2.17 Further Assurances. After the Effective Time, the officers and directors of the Surviving Corporation will be authorized to execute and deliver, in the name and on behalf of the Company, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of the Company, any other actions and things to vest, perfect or confirm of record or otherwise in the Surviving Corporation any and all right, title and interest in, to and under any of the rights, properties or assets acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger.

               (a) Each of the Company and TNCLP has timely filed or furnished all reports, schedules, forms, statements and other documents required to be filed or furnished by it with or to the SEC since January 1, 2009 (together with all exhibits, financial statements and schedules thereto and all information incorporated therein by reference, the “Company SEC Documents”).

               (b) Each of Parent and the Company shall, as promptly as practicable after receipt thereof, provide the other Party copies of any written comments and advise the other Party of any oral comments, with respect to the Post-Effective Amendment or Proxy Statement, as the case may be, received from the SEC. Each of Parent and the Company shall provide the other Party with a reasonable opportunity to review and comment on any amendment or supplement to the Post-Effective Amendment or Proxy Statement, as the case may be, and any communications prior to filing such with the SEC and will promptly provide the other Party with a copy of all such filings and communications made with the SEC.

               (c) If at any time prior to the Effective Time, (i) any event or change occurs with respect to the Parties or any of their respective Affiliates, officers or directors, which should be set forth in an amendment of, or a supplement to, the Post-Effective Amendment or Proxy Statement or (ii) any information relating to the Parties, or any of their respective Affiliates, officers or directors, should be discovered by any of the Parties which should be set forth in an amendment or a supplement to the Post-Effective Amendment or Proxy Statement so that the Post-Effective Amendment or Proxy Statement would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, Parent or the Company, as the case may be, shall file as promptly as practicable with the SEC an amendment of, or a supplement to, the Post-Effective Amendment or Proxy Statement and, as required by Law, disseminate the information contained in such amendment or supplement to the stockholders of the Company.

          Section 6.2 Company Stockholders Meeting; Recommendation.

               (a) If the Company Stockholder Approval is required by applicable Law, as promptly as reasonably practicable after the Post-Effective Amendment is declared effective under the Securities Act, the Company shall duly take all necessary actions to duly call, give notice of, convene and hold a meeting of the stockholders of the Company (such meeting, or any adjournments or postponements thereof, the “Company Stockholders Meeting”) for the purpose of obtaining the Company Stockholder Approval and shall, subject to Section 6.2(b), use best efforts to solicit its stockholders to obtain the Company Stockholder Approval.

               (b) The Board of Directors of the Company shall, subject to this Section 6.2(b), make the Company Recommendation to the stockholders of the Company and include the Company Recommendation and the Company Fairness Opinion in the Proxy Statement. Neither the Board of Directors of the Company nor any committee thereof, shall, directly or indirectly, withdraw, modify, amend or qualify the Company Recommendation in a manner adverse to Parent or Merger Sub (or publicly propose to take any of the foregoing actions) or execute or enter into, any letter of intent, memorandum of understanding, merger agreement or other written agreement providing for a Takeover Proposal (other than a confidentiality agreement permitted pursuant to Section 6.5(a)) (a “Change in Company Recommendation”) except in accordance with Section 6.5(c).

               (c) Notwithstanding any Change in Company Recommendation, unless this Agreement is terminated pursuant to, and in accordance with, Section 8.1 prior to the Company Stockholders Meeting, if the Company Stockholder Approval is required by applicable Law, the Company shall submit this Agreement to the stockholders of the Company for the purpose of obtaining the Company Stockholder Approval. For the avoidance of doubt, unless this Agreement is terminated pursuant to, and in accordance with, Section 8.1, no Change in Company Recommendation shall effect the approval by the Board of Directors of the Company of the Merger for purposes of Section 3-106 of the MGCL.

          Section 6.3 Access to Information.

               (a) Upon reasonable notice, the Company shall, and shall cause each Company Subsidiary to, afford to the officers, directors, employees, accountants, counsel, financial

advisors, consultants, Financing Sources and other advisors or representatives (collectively, “Representatives”) of Parent access during normal business hours to all of the Company’s and the Company Subsidiaries’ properties, books, records, contracts, commitments and personnel, but only to the extent that such access does not unreasonably interfere with the business or operations of the Company and the Company Subsidiaries, and the Company shall, and shall cause each of the Company Subsidiaries to, furnish as promptly as practicable to Parent (i) a copy of each material report, schedule and other document filed, furnished, published, announced or received by it during such period pursuant to the requirements of federal or state securities Laws or a Governmental Entity and (ii) all other information with respect to the Company as Parent may reasonably request; provided, however, that none of Parent, any Parent Subsidiary or any of their respective Representatives shall conduct any environmental sampling or surface or subsurface assessment or investigation; and provided further that the Company may withhold any document or information (i) to the extent that such document or information is subject to the terms of a confidentiality agreement with a third party (provided that the Company shall use its reasonable best efforts to obtain waivers under such agreements or implement requisite procedures to enable reasonable access without violating such agreements), (ii) to the extent that the disclosure thereof would, in the Company’s good faith opinion after consultation with legal counsel, result in the loss of attorney-client privilege with respect to such document or information (provided that the Company shall use its reasonable best efforts to put in place an arrangement to permit such disclosure without loss of attorney-client privilege), (iii) to the extent required by applicable Law (provided that the Company shall use its reasonable best efforts to enable the provision of reasonable access without violating such Law) or (iv) to the extent that the disclosure thereof would, in the Company’s reasonable discretion, result in significant antitrust risk.

               (b) All information exchanged pursuant to Section 6.3(a) and all analyses, compilations, computer disks, forecasts, studies, or other documents prepared by Parent, Merger Sub or their respective Representatives that contain or reflect any such information, and any information stored in digital or analog form, whether on electronic or magnetic media, and pictures thereof stored on film or tape or electronically stored (collectively, the “Information”) will be kept confidential and, without the prior written consent of the Company, neither Parent, Merger Sub nor any of their respective Representatives will (expect as provided in this Section 6.3(b)) disclose any Information; provided, however, that Parent and Merger Sub may reveal the Information to their respective Representatives who (a) are acting for Parent or Merger Sub in connection with the transactions contemplated by this Agreement; (b) need to know the Information for such purposes; (c) are informed by Parent of the confidential nature of the Information and (d) agree to act in accordance with the terms of this Section 6.3(b). If Parent or Merger Sub or any of their respective Representatives are required by Law or in connection with a legal proceeding or legal process to disclose any of the Information, Parent will notify the Company promptly in writing (if not legally prohibited from doing so) so that the Company may seek a protective order or other appropriate remedy or waive compliance with the terms of this Section 6.3(b), and Parent shall reasonably cooperate with the Company, at the Company’s expense, in seeking such protective order or other remedy. If no such protective order or other remedy is obtained, or if the Company does not waive compliance with the applicable terms of this Section 6.3(b), Parent, Merger Sub or their respective Representative required to disclose the Information will disclose only that portion which Parent, Merger Sub or their respective Representative is advised by counsel is legally required to be disclosed and will exercise its commercially reasonable efforts to obtain reliable assurances that confidential treatment will be accorded such Information as far in advance of its disclosure as

reasonably practicable. This Section 6.3(b) does not apply to such portions of the Information which (i) are or become generally available to the public (other than as a result of a disclosure by Parent, Merger Sub or their respective Representatives in breach of this Section 6.3(b)), (ii) are (as evidenced by written documentation) or become available to Parent, Merger Sub or their respective Representatives on a nonconfidential basis from a source other than the Company or one of its Representatives which, to the knowledge of the receiving party after reasonable inquiry, is not prohibited from disclosing it by a legal, contractual or fiduciary obligation, or (iii) have been independently developed without using, containing or reflecting any information furnished by the Company or its Representatives.

          Section 6.4 Efforts; Consents and Approvals.

               (a) Subject to the terms and conditions of this Agreement (including Section 6.2, Section 6.4(b), Section 6.4(c) and Section 6.17), each of Parent and the Company shall cooperate to obtain all consents to the Offer, the Merger and the other transactions contemplated hereby that are contemplated by or identified in this Agreement or the Company Disclosure Letter and shall use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary or advisable under applicable Law to consummate the transactions contemplated by this Agreement, including preparing and filing as promptly as practicable all documentation to effect all necessary or advisable filings, notices, petitions, statements, registrations, submissions of information, applications and other documents necessary to consummate the transactions contemplated by this Agreement.

               (b) In furtherance and not in limitation of the other provisions of this Section 6.4, Parent and the Company shall, as promptly as practicable, file with all applicable U.S. and foreign Governmental Entities any notices and applications necessary to obtain merger control, competition or foreign investment Law approval (including approvals under Foreign Competition Laws) for the Offer and the Merger; provided that each of Parent and the Company shall consult and cooperate with one another in connection with the preparation of any such notices and applications prior to their filing, consistent with applicable Law. All notices and applications shall be in substantial compliance with the applicable requirements of Foreign Competition Law or U.S. Law, as applicable. Each of the Company and Parent shall furnish to the other such necessary information and reasonable assistance as the other may request in connection with its preparation of any filing or submission which is necessary under any Foreign Competition Law or U.S. Law, as applicable. Each of the Company and Parent shall keep each other apprised of the status of any communications with, and any inquiries or requests for additional information from, any Governmental Entity and shall comply with any such inquiry or request as promptly as practicable, but in no event later than five (5) Business Days after receipt of such inquiry or request, or as otherwise agreed to by the Parties, which agreement shall not be unreasonably withheld. Any such additional information shall be in substantial compliance with the applicable requirements of any Foreign Competition Law or U.S. Law, as applicable. Each of the Company and Parent shall not independently participate in any meeting, or engage in any substantive conversation, with any Governmental Entity in respect of any filing, investigation or inquiry concerning this Agreement, the Offer, the Merger or the transactions contemplated hereby (including the expected or proposed timing of consummation of the Offer, the Merger or the other transactions contemplated hereby) without giving the other Party prior notice of the meeting or conversation and, unless prohibited by any such Governmental Entity, the opportunity to attend or participate. Each of the Company and

Parent shall consult and cooperate with one another in connection with any analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals made or submitted by or on behalf of any Party in connection with proceedings under or relating to any Foreign Competition Law or U.S. Law. Each of the Company and Parent agrees not to extend, directly or indirectly, any waiting period under any Foreign Competition Law or U.S. Law or enter into any agreement with a Governmental Entity to delay or not to consummate the transactions contemplated by this Agreement, except with the prior written consent of the other Party. Each Party shall furnish the other Party’s outside counsel with copies of all correspondence, filings and written communications between such Party or any of its Subsidiaries, Affiliates or Representatives and any Governmental Entity or its respective staff with respect to this Agreement, the Offer, the Merger or the transactions contemplated hereby.

               (c) Without limiting the generality of each Party’s obligations pursuant to Section 6.4(b), each of the Company and Parent shall use its best efforts to obtain, as promptly as practicable, any clearance required under any Foreign Competition Law or U.S. Law, as applicable, for the consummation of the Offer and the Merger, including, in the case of Parent, by (i) selling, holding separate or otherwise disposing of, or proposing and agreeing to sell, hold separate or otherwise dispose of, or permitting the sale, holding separate or other disposition of, any assets of Parent or its Subsidiaries, or after the Closing, the Company, its Subsidiaries, GrowHow, HATLP, OCOP or PLNL, and (ii) conducting its business in a specified manner, or proposing and agreeing or permitting Parent or its Subsidiaries, or after the Closing, the Company, its Subsidiaries, GrowHow, HATLP, OCOP or PLNL, to conduct its business in a specified manner (each a “Divestiture Action”). Notwithstanding anything to the contrary contained herein, in no event shall Parent be required to agree, pursuant to any Divestiture Action, to take any action that would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on the Company or Parent (without giving effect to clause (viii) of the definition thereof). In the event that any administrative or judicial action or proceeding is instituted (or threatened to be instituted) challenging any transaction contemplated by this Agreement as violative of any competition, antitrust, foreign investment or other Law, or if any Law is enacted, entered, promulgated or enforced by a Governmental Entity that would make the transactions contemplated by this Agreement illegal or would otherwise prohibit or materially impair or delay the consummation of the transactions contemplated by this Agreement, Parent shall use its best efforts to resolve, contest and resist any such action or proceeding and to have vacated, lifted, reversed or overturned any Order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents, delays or restricts consummation of the transactions contemplated by this Agreement and to have such Law repealed, rescinded or made inapplicable so as to permit prompt consummation of the transactions contemplated by this Agreement, including by taking any Divestiture Action.

          Section 6.5 No Solicitation.

               (a) The Company shall not, nor shall it authorize or permit any of its Subsidiaries to, and it shall cause its and its Subsidiaries’ respective Representatives not to, directly or indirectly: (i) initiate or solicit or knowingly facilitate or encourage (it being understood that providing information in the ordinary course of business consistent with past practice to categories of Persons to whom the Company routinely provides such information in the ordinary course of business consistent with past practice will not, in and of itself, constitute encouragement hereunder) any inquiry or the making of any proposal that constitutes a Takeover Proposal or (ii) continue or

otherwise participate in any discussions or negotiations regarding, furnish to any Person any information or data or access to its properties with respect to, or otherwise cooperate with or knowingly take any other action to facilitate any proposal that constitutes any Takeover Proposal. The Company shall, and shall cause its Subsidiaries and its and their respective Representatives to, immediately cease and cause to be terminated all existing discussions or negotiations with any Person conducted heretofore with respect to any Takeover Proposal (and shall not waive or otherwise modify any existing standstill provision or confidentiality agreement that benefits the Company) and request from each Person that has executed a confidentiality agreement with the Company the prompt return or destruction of any confidential information previously furnished to such Person in connection therewith. Notwithstanding the foregoing, prior to the Acceptance Time, the Company and its Representatives, in response to a bona fide written Takeover Proposal that was made after the date of this Agreement and did not result from a material breach of this Agreement and that (1) constitutes a Superior Proposal or (2) the Board of Directors of the Company determines in good faith (after consultation with outside counsel and a financial advisor of nationally recognized reputation) could reasonably be expected to result in a Superior Proposal, shall be permitted to: (A) provide access to non-public information to the Person making such Takeover Proposal pursuant to and in accordance with an executed confidentiality agreement not less restrictive of the other party than the provisions of Section 6.3(b); provided that all such information provided to such Person has previously been provided to Parent or is provided to Parent prior to or substantially concurrently with the time it is provided to such Person; and (B) participate in discussions or negotiations with respect to such Takeover Proposal with the Person making such Takeover Proposal.

               (b) From and after the date of this Agreement, as promptly as practicable after the receipt, directly or indirectly, by the Company of any Takeover Proposal or any inquiry with respect to, or that could reasonably be expected to lead to, any Takeover Proposal, and in any case within two (2) Business Days after the receipt thereof, the Company shall provide oral and written notice to Parent of (i) such Takeover Proposal or inquiry, (ii) the identity of the Person making any such Takeover Proposal or inquiry and (iii) the material terms and conditions of any such Takeover Proposal or inquiry. The Company shall keep Parent fully informed on a current basis of the status of any such Takeover Proposal, including any changes to the terms and conditions thereof.

               (c) At any time prior to the Acceptance Time, the Board of Directors of the Company may (i) effect a Change in Company Recommendation; provided that the Board of Directors of the Company determines in good faith, after consultation with outside counsel, that the failure to do so would be inconsistent with its duties to the stockholders of the Company under applicable Law, and (ii) in response to a Superior Proposal that was made after the date of this Agreement and did not result from a material breach of this Agreement, cause the Company to terminate this Agreement and concurrently with such termination, upon payment of the Termination Fee and the Parent Reimbursement Fee pursuant to Section 8.2(b)(i), enter into a definitive agreement with respect to such Superior Proposal. Notwithstanding the foregoing, the Company shall not be entitled to exercise its right to effect a Change in Company Recommendation or its right to terminate this Agreement pursuant hereto unless (A) the Board of Directors of the Company shall have first provided prior written notice to Parent advising Parent that the Board of Directors of the Company intends to (x) effect a Change in Company Recommendation (a “Notice of Change in Company Recommendation”) which notice shall contain a description of the events,

facts and circumstances giving rise to such proposed action or (y) terminate this Agreement pursuant to this Section 6.5(c) in response to a Superior Proposal (a “Notice of Superior Proposal”) which notice shall contain a description of the terms and conditions of the Superior Proposal (including a copy of any such written Superior Proposal) and (B) Parent does not make, within five (5) Business Days after receipt of such Notice of Change in Company Recommendation or Notice of Superior Proposal, as the case may be (it being understood and agreed that, with respect to a Notice of Superior Proposal, any amendment to the financial terms or any other material term of such Superior Proposal shall require a new Notice of Superior Proposal and a new five (5) Business Day period), a proposal that would, in the good faith determination of the Board of Directors of the Company (after consultation with outside counsel and a financial advisor of nationally recognized reputation), cause such events, facts and circumstances to no longer form the basis for the Board of Directors of the Company to effect a Change in Company Recommendation, in the case of a Notice of Change in Company Recommendation, or be at least as favorable to the stockholders of the Company as such Superior Proposal, in the case of a Notice of Superior Proposal. The Company agrees that, during the five (5) Business Day period after Parent’s receipt of a Notice of Change in Company Recommendation or Notice of Superior Proposal, as the case may be, the Company and its Representatives shall negotiate in good faith with Parent and its Representatives regarding any revisions to the terms of this Agreement proposed by Parent.

               (d) Nothing contained in this Section 6.5 shall prohibit the Company from (i) taking, and disclosing to its stockholders, a position contemplated by Rule 14e-2(a) under the Exchange Act or a statement required under Rule 14d-9 under the Exchange Act or (ii) making any disclosure to stockholders of the Company that is required by applicable Law; provided, however, that the taking of any such position or making of any such disclosure contemplated by clauses (i) or (ii) above shall be subject to and only taken in compliance with Section 6.2 and, to the extent applicable, Section 6.5(c).

          Section 6.6 Employee Matters.

               (a) From the Acceptance Time through no earlier than December 31 of the calendar year following the calendar year in which the Closing Date occurs (the “Continuation Period”), the Company or, if after the Effective Time, the Surviving Corporation shall cause each individual who is employed by the Company and any Company Subsidiary immediately before the Acceptance Time (each, a “Continuing Employee”) to be provided with (i) base compensation and bonus or incentive opportunities that are no less favorable in the aggregate than the base compensation and bonus or incentive opportunities (including value attributable to equity-based compensation) provided to such Continuing Employee immediately prior to the Acceptance Time and (ii) employee benefits that are substantially comparable in the aggregate to those provided to such Continuing Employee immediately prior to the Acceptance Time. Except to the extent necessary to avoid the duplication of benefits, the Company or, if after the Effective Time, the Surviving Corporation shall recognize the service of each Continuing Employee prior to the Acceptance Time as if such service had been performed with Parent or its Affiliates (A) for all purposes under the Company Benefit Plans maintained by the Company or the Surviving Corporation or their respective Affiliates after the Acceptance Time (to the extent such plans, programs or agreements are provided to Continuing Employees), (B) for purposes of eligibility and vesting under any employee benefit plans and programs of the Company or the Surviving Corporation or their respective ERISA Affiliates other than the Company Benefit Plans (the

“Surviving Corporation Plans”) in which the Continuing Employee participates after the Acceptance Time and (C) for purposes of determination of benefit accruals and benefit levels with respect to vacation, paid time off and severance under any Surviving Corporation Plan in which the Continuing Employee participates after the Acceptance Time (excluding, for the avoidance of doubt, benefit accrual under any defined benefit pension plans and non-qualified retirement plans), in each case to the same extent such Continuing Employee’s service was recognized by the Company and the Company Subsidiaries under the corresponding Company Benefit Plan in which such Continuing Employee participated immediately before the Acceptance Time. In addition, and without limiting the generality of the foregoing, each Continuing Employee shall be immediately eligible to participate, without any waiting time, in any and all Surviving Corporation Plans to the extent coverage under any such plan replaces coverage under a comparable benefit plan in which such Continuing Employee participates immediately before the Acceptance Time. For the avoidance of doubt, following the Acceptance Time, neither the Company nor the Surviving Corporation shall have any obligation to grant equity awards to the Continuing Employees.

               (b) With respect to any welfare plan maintained by the Company or the Surviving Corporation or their respective Affiliates in which Continuing Employees are eligible to participate after the Acceptance Time, the Company, the Surviving Corporation and their respective Affiliates shall (i) waive all limitations as to pre-existing conditions, exclusions and waiting periods and actively-at-work requirements with respect to participation and coverage requirements applicable to such employees and their eligible dependents and beneficiaries, to the extent such limitations were waived, satisfied or did not apply to the applicable employee or eligible dependent or beneficiary under the corresponding welfare Company Benefit Plan in which he or she participated immediately prior to the Acceptance Time, and (ii) provide each Continuing Employee and his or her eligible dependents and beneficiaries with credit for any co-payments and deductibles paid prior to the Acceptance Time in satisfying any analogous deductible or out-of-pocket requirements to the extent applicable under any such plan and to the same extent such credit was provided to him or her under the corresponding welfare Company Benefit Plan in which he or she participated immediately prior to the Acceptance Time, in each case without duplication of benefits.

               (c) Without limiting the generality of Section 6.6(a), from and after the Acceptance Time, the Company, the Surviving Corporation and their respective Affiliates shall assume, honor and continue during the Continuation Period, or if sooner, until all obligations thereunder have been satisfied, all of the Company Benefit Plans that are employment, severance, retention and termination plans, policies, programs, agreements and arrangements (including any change in control severance agreement between the Company and any Continuing Employee) maintained by the Company or any Company Subsidiary, in each case as in effect at the Acceptance Time and as set forth on Section 6.6(c) of the Company Disclosure Letter, including with respect to any payments, benefits or rights arising as a result of the transactions contemplated by this Agreement (either alone or in combination with any other event), without any amendment or modification, other than (i) as required pursuant to the terms of any Company Benefit Plan (including any collective bargaining agreement) as in effect on the date of this Agreement, (ii) as required to comply with applicable Law or GAAP or (iii) as expressly permitted by this Agreement.

               (d) Without limiting the generality of Section 6.6(a), with respect to the annual performance period in which the Acceptance Time occurs, the Company, the Surviving

Corporation and their respective Affiliates shall (i) honor and continue in all material respects the Company Benefit Plans that are cash incentive compensation plans maintained by the Company and any Company Subsidiary at the Acceptance Time, as set forth on Section 6.6(d) of the Company Disclosure Letter (the “Incentive Plans”), pursuant to their respective terms (except as modified by the following clauses (ii) and (iii)) as in effect at the Acceptance Time with respect to the annual performance period thereunder commencing prior to and ending after the Acceptance Time, (ii) at the time(s) prescribed by the Incentive Plans as in effect at the Acceptance Time, make payments to the Continuing Employees in accordance with the applicable material terms of the Incentive Plans as in effect at the Acceptance Time (subject to any plan provision requiring an employee to remain continuously employed following the end of the relevant performance period and up to the date that payments under the applicable Incentive Plan are made) and (iii) provide any Continuing Employee whose employment is terminated at or after the Acceptance Time by the Company, Parent, the Surviving Corporation or their respective Subsidiaries without “Cause” (as such term is defined in Section 6.6(d) of the Company Disclosure Letter) prior to the time at which such payments are made with an amount in cash as described on Section 6.6(d) of the Company Disclosure Letter, prorated to reflect the portion of such annual performance period that elapsed prior to such termination (if such termination occurs prior to the end of such performance period), payable at the same time such bonus (if any) would have been paid had such termination not occurred (but in any event within the period required by Section 409A of the Code, such that it qualifies as a “short-term deferral” pursuant to Section 1.409A-1(b)(4) of the Department of Treasury Regulations).

               (e) Without limiting the generality of Section 6.6(a), during the Continuation Period, if the Company, the Surviving Corporation and their respective Affiliates terminate the employment of any Continuing Employee (other than any employee who is party to a Company Benefit Plan that is an employment, change in control, severance or other individual agreement) other than for “Cause” (as such term is defined in Section 6.6(d) of the Company Disclosure Letter), the Company, the Surviving Corporation and their respective Affiliates shall pay to such Continuing Employee severance in an amount equal to the greater of (i) the severance benefits due under the applicable severance plan, policy or guidelines of the Company, the Surviving Corporation and their respective Affiliates then in effect for similarly situated employees of the Company, the Surviving Corporation and their respective Affiliates, and (ii) the severance benefits that would have been due under the applicable severance plan, policy or guidelines of the Company or any Company Subsidiary that was applicable to such Continuing Employee immediately prior to the Acceptance Time. Without limiting the generality of Section 6.6(a), the level of severance benefits a terminated Continuing Employee is entitled to receive pursuant to clauses (i) and (ii) of the preceding sentence shall be determined by taking into account such employee’s service with the Company and any Company Subsidiary (and any predecessor) prior to the Acceptance Time (to the same extent such service would have been recognized under the severance plan, policy or guidelines of the Company or any Company Subsidiary that was applicable to such Continuing Employee immediately prior to the Acceptance Time) and such employee’s service with the Company, the Surviving Corporation and their respective Affiliates on and after the Acceptance Time.

               (f) Notwithstanding anything herein to the contrary, Parent, Merger Sub and the Company acknowledge and agree that all provisions contained in this Section 6.6 are included for the sole benefit of Parent, Merger Sub and the Company, and that nothing in this

Agreement, whether express or implied, (i) shall be treated as an amendment or other modification of any Company Benefit Plan or other employee benefit plan, agreement or other arrangement, (ii) shall limit the right of Parent, Merger Sub, the Company or their respective Affiliates to amend, terminate or otherwise modify any Company Benefit Plan or other employee benefit plan, agreement or other arrangement following the Acceptance Time or (iii) shall create any third party beneficiary or other right (x) in any other Person, including any current or former director, officer, employee or independent contractor of the Company or any Company Subsidiary or any participant in any Company Benefit Plan or other employee benefit plan, agreement or other arrangement (or any dependent or beneficiary thereof) or (y) to continued employment with Parent, Merger Sub, the Company or any of their respective Affiliates.

               (g) All compensatory and similar arrangements that the Company or any of its Subsidiaries may make or enter into prior to the expiration date of the Offer, including any payments that may be or become payable, and any benefits that may be granted, according to employment compensation, severance and other employee benefit plans, contracts or arrangements, shall (a) be made or entered into in consideration of, or paid or granted as compensation for, past services performed, future services to be performed or future services to be refrained from performing (and matters incidental thereto) and (b) not be calculated based on the number of shares of Company Common Stock tendered or to be tendered in the Offer. Moreover, the Company (acting through the Compensation Committee of the Company Board of Directors) shall take such steps as may be required so that, prior to the expiration date of the Offer: (i) the adoption, approval, amendment or modification of each Change in Control Arrangement (as defined below) shall be approved as an employment compensation, severance or other employee benefit arrangement solely by independent directors of the Company in accordance with the requirements of Rule 14d-10(d)(2) under the Exchange Act and the instructions to such Rule and (ii) the “safe harbor” provided pursuant to Rule 14d-10(d)(2) under the Exchange Act shall be satisfied with respect to each such Change in Control Arrangement, and any amendment or modification thereof, as a result of the taking by the Company Board of Directors, the Compensation Committee of the Company Board of Directors or its independent directors prior to the expiration date of the Offer of all necessary actions. “Change in Control Arrangement” shall mean each employment compensation, severance and other employee benefit plan, contract or arrangement of the Company or any of its Subsidiaries pursuant to which any holder of Company Common Stock could become entitled to (A) any additional compensation, enhanced severance or other benefits or any acceleration of the time of payment or vesting of any compensation, severance or other benefits or any funding of any compensation or benefits by the Company or any of its Subsidiaries, in each case as a result of the Offer, the obtaining of the Company Stockholder Approval or the consummation of the Merger or other transactions contemplated by this Agreement (alone or in combination with any other event), or (B) any other compensation or benefits from the Company or any of its Subsidiaries related to or contingent upon or the value of which would be calculated on the basis of the Offer, the Merger or any of the other transactions contemplated by this Agreement (alone or in combination with any other event).

          Section 6.7 Fees and Expenses. Whether or not the Offer or the Merger is consummated, all expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the Party incurring such expenses.

          Section 6.8 Directors’ and Officers’ Indemnification and Insurance.

               (a) From and after the Acceptance Time, Parent shall cause the Company and if after the Effective Time the Surviving Corporation to the greatest extent permitted by Law (a) to indemnify and hold harmless, against any costs or expenses (including attorney’s fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, and provide advancement of expenses (without requiring a preliminary determination as to the ultimate entitlement to indemnification) to, all past and present directors and officers of the Company (in all of their capacities) (the “Indemnified Persons”) to the same extent such persons are indemnified or have the right to advancement of expenses as of the date of this Agreement by the Company pursuant to the Company’s Constituent Documents and indemnification agreements, if any, in existence on the date hereof with any Indemnified Persons and (b) to honor the provisions regarding elimination of liability of directors, indemnification of officers and directors and advancement of expenses contained in the Company’s Constituent Documents and indemnification agreements immediately prior to the Acceptance Time.

               (b) From and after the Acceptance Time, Parent shall cause the Company and if after the Effective Time the Surviving Corporation to maintain for a period of six (6) years after the Effective Time the current policies of directors’ and officers’ liability insurance and fiduciary liability insurance (“D & O Insurance”) maintained by the Company; provided that the Company and the Surviving Corporation may substitute therefor policies of at least the same coverage and amounts containing terms and conditions which are, individually and in the aggregate, at least as protective and no less advantageous to the insured with respect to claims arising from facts or events that occurred on or before the Effective Time (including for acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby); provided, further, that in no event shall the Company or the Surviving Corporation be required to expend in any one (1) year more than three hundred percent (300%) of the current annual premium expended by the Company and the Company Subsidiaries to maintain or procure such D & O Insurance immediately prior to the Acceptance Time (such three hundred percent (300%) amount, the “Maximum Annual Premium”); provided, further, that if the annual premiums of such insurance coverage exceed such amount, the Company and the Surviving Corporation shall obtain a policy with the greatest coverage available for a cost not exceeding the Maximum Annual Premium. Alternatively, prior to the Acceptance Time, either Parent or, if Parent does not do so prior to three (3) Business Days prior to the Acceptance Time, the Company may purchase a six-year prepaid “tail” policy containing terms and conditions which are, individually and in the aggregate, at least as protective and no less advantageous to the insured than the D & O Insurance maintained by the Company with respect to claims arising from facts or events that occurred on or before the Acceptance Time (including for acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby); provided, however, that in no event shall any policy require payment of aggregate premiums for such insurance in excess of the aggregate Maximum Annual Premium for such six-year period. If such prepaid “tail” policy has been obtained by the Company, Parent shall cause such policy to be maintained in full force and effect, for its full term, and cause all obligations thereunder to be honored by it and the Surviving Corporation.

               (c) The obligations of the Surviving Corporation under this Section 6.8 shall not be terminated or modified in such a manner as to adversely affect any indemnitee to whom this Section 6.8 applies without the consent of such affected indemnitee (it being expressly

agreed that the indemnitees to whom this Section 6.8 applies shall be third-party beneficiaries of this Section 6.8).

          Section 6.9 Public Announcements. Parent and the Company shall develop a joint communications plan and each Party shall (a) unless otherwise required by applicable Law, ensure that all press releases and other public statements or communications with respect to the transactions contemplated hereby shall be consistent with such joint communications plan and (b) unless otherwise required by applicable Law or by obligations pursuant to any listing agreement with or rules of any securities exchange, consult with each other before issuing any press release or, to the extent practicable, otherwise making any public statement or communication with respect to this Agreement or the transactions contemplated hereby.

          Section 6.10 Notice of Certain Events. Each of Parent and the Company shall promptly notify the other after receiving or becoming aware of (a) any notice or other communication from any Person alleging that the consent of that Person is or may be required in connection with the transactions contemplated by this Agreement and (b) the occurrence or non-occurrence of any event the occurrence or non-occurrence of which would be reasonably likely, (i) in the case of the Company, to result in the existence of the events or conditions set forth in subparagraphs (b) and (c) of Annex I or (ii), in the case of Parent, to result in the existence of the events or conditions set forth in the paragraph immediately following Section 8.1(d)(i).

          Section 6.11 Listing of Shares of Parent Common Stock. Parent shall use its reasonable best efforts to cause the shares of Parent Common Stock to be issued in the Offer and Merger to be approved for listing on the NYSE prior to the Acceptance Time.

          Section 6.12 Section 16 of the Exchange Act. Prior to the Effective Time, the Company shall take all reasonable actions intended to cause any dispositions of shares of Company Common Stock in the Merger by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act, to be exempt under Rule 16b-3 promulgated under the Exchange Act, as described in the No-Action Letter dated January 12, 1999, issued by the SEC to Skadden, Arps, Slate, ▇▇▇▇▇▇▇ & ▇▇▇▇ LLP.

          Section 6.13 State Takeover Laws. If any “fair price,” “business combination” or “control share acquisition” statute or other similar statute or regulation is or shall become applicable to the transactions contemplated hereby, the Company and its Board of Directors shall use their reasonable best efforts to ensure that the transactions contemplated hereby may be consummated as promptly as practicable on the terms contemplated hereby and shall otherwise act to minimize the effects of any such statute or regulation on the transactions contemplated hereby.

          Section 6.14 Stockholder Litigation. Each of the Company and Parent shall promptly advise the other Party orally and in writing of any litigation brought by any stockholder of the Company or Parent against the Company or Parent and/or their respective directors relating to this Agreement and/or the transactions contemplated by this Agreement, including the Offer and the Merger, and shall keep the other Party fully informed regarding any such litigation. Each of the Company and Parent shall give the other Party the opportunity to participate in, subject to a customary joint defense agreement, but not control the defense or settlement of any such litigation, shall give due consideration to the other Party’s advice with respect to such litigation and shall not

settle any such litigation without the prior written consent of the other Party (not to be unreasonably withheld or delayed).

          Section 6.15 Transfer Taxes. If the Effective Time occurs, all stock transfer, real estate transfer, documentary, stamp, recording and other similar taxes (including interest, penalties and additions to any such taxes) incurred in connection with this Agreement and the transactions contemplated hereby shall, except as provided in Section 2.1(e) and Section 2.14(c), be paid by Parent.

          Section 6.16 Accountant’s Letters(a) . Each of Parent and the Company shall use reasonable best efforts to cause to be delivered to the other Party (and, in the case of the Form S-4, to the dealer-managers named therein) letters from their respective independent accountants, one letter dated as of the date the Form S-4 is declared effective (and one dated as of the date the Post-Effective Amendment is declared effective if the Post-Effective Amendment is required) and one dated approximately as of the date of the Acceptance Time (and one dated as of the Closing Date if the Post-Effective Amendment is required), in form and substance reasonably satisfactory to the other Party (and in the case of the Form S-4, to the dealer-mangers named therein) and customary in scope and substance for comfort letters delivered by independent public accountants in connection with registration statements similar to the Form S-4 and the Post-Effective Amendment, if required; provided that the failure of any such letter to be delivered shall not result in a failure of a condition to the Offer or the Merger.

          Section 6.17 Financing.

               (a) Parent shall use its best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to consummate and obtain the Financing on the terms and conditions described in the Commitment Letter, including using best efforts to (i) maintain in effect the Commitment Letter, (ii) negotiate and enter into definitive agreements with respect thereto on terms and conditions contemplated by the Commitment Letter, (iii) satisfy on a timely basis all conditions applicable to Parent in the Commitment Letter that are within its control and comply with its obligations thereunder, and (iv) consummate the Financing no later than the Acceptance Time. Parent shall have the right from time to time to amend, replace, supplement or otherwise modify, or waive any of its rights under, the Commitment Letter and/or substitute other debt or equity financing for all or any portion of the Financing from the same and/or alternative financing sources, provided that any such amendment, replacement, supplement or other modification to or waiver of any provision of the Commitment Letter that amends the Financing and/or substitution of all or any portion of the Financing shall not prevent or impede or delay the consummation of the Offer, the Merger and the other transactions contemplated by this Agreement and shall be subject to Section 6.23. If any portion of the Financing becomes unavailable or Parent becomes aware of any event or circumstance that makes any portion of the Financing unavailable, in each case, on the terms and conditions contemplated in the Commitment Letter and such portion is reasonably required to fund the cash portion of the Offer Price or the Merger Consideration and all fees, expenses and other amounts contemplated to be paid by Parent pursuant to this Agreement, Parent shall use its best efforts to arrange and obtain alternative financing from alternative financial institutions in an amount sufficient to consummate the transactions contemplated by this Agreement upon conditions no less favorable to Parent and the

Company than those in the Commitment Letter as promptly as practicable following the occurrence of such event.

               (b) In the event that the Commitment Letter is amended, replaced, supplemented or otherwise modified, including as a result of obtaining alternative financing in accordance with Section 6.17(a), or if Parent substitutes other debt or equity financing for all or a portion of the Financing, in each case to the extent permitted pursuant to Section 6.17(a), each of Parent and the Company shall comply with its covenants set forth herein with respect to the Commitment Letter as so amended, replaced, supplemented or otherwise modified and with respect to such other debt or equity financing to the same extent that Parent and the Company would have been obligated to comply with respect to the Financing.

          Section 6.18 Assistance with Financing.

               (a) In order to assist Parent in any way necessary, proper or advisable in connection with Parent’s arrangement of the Financing, the Company shall, and shall cause each of its Subsidiaries to, at the expense of Parent, provide such assistance and cooperation as Parent, Merger Sub and their Affiliates may reasonably request in connection with the arrangement of the Financing and the satisfaction, on a timely basis, of all conditions applicable to Parent and Merger Sub (or its or their Affiliates) in any definitive documents relating thereto including, (i) furnishing to Parent and its Representatives, to the extent reasonably available, pertinent information with respect to the Company and its Subsidiaries (or, to the extent required and reasonably available to it, GrowHow, HATLP, OCOP or PLNL) and their respective operations to be included in any prospectus, offering memorandum, rating agency presentations, bank book, information memorandum, lender presentation or similar document or marketing material (including historical financial statements prepared in accordance with GAAP and projected financial statements of the Company for inclusion in any such document, the “Required Information”), and assisting in the preparation of such documents (including the preparation of any pro forma financial information required to be included in any such document) and cooperating with and attending a reasonable number of meetings with prospective investors or lenders, (ii) requesting its independent accountants to provide reasonable assistance to Parent or Merger Sub consistent with their customary practice (including to provide consent to Parent or Merger Sub to prepare and use their audit reports relating to the Company and any necessary “comfort letters” in each case on customary terms and consistent with their customary practice in connection with the Financing), (iii) providing reasonable cooperation with prospective investors, arrangers and lenders and their respective advisors in performing their due diligence and (iv) providing all required information reasonably available to it relating to any indebtedness of the Company or its Subsidiaries whose terms require or permit it to be declared due and payable, or provide that it becomes automatically due and payable, prior to its stated maturity as a result of, or in connection with, the Offer or the Merger. The Company will use its reasonable best efforts to update the Required Information from time to time as may be necessary such that such Required Information does not contain any untrue statement of material fact or omit to state any material fact necessary in order to make the statements therein not misleading.

               (b) In no event shall the Company or its Subsidiaries be required to pay any commitment or similar fee or incur any other liability in connection with the Financing prior to the Effective Time. The requested cooperation shall not unreasonably interfere with the ongoing

operations of the Company and its Subsidiaries or otherwise materially impair the ability of any officer or executive of the Company to carry out their duties to the Company.

               (c) Parent and Merger Sub shall indemnify and hold harmless the Company and its Subsidiaries and its and their directors, officers, employees and agents from and against any and all losses or damages suffered or incurred by them in connection with the arrangement of the Financing and any information utilized in connection therewith; provided, however, that the foregoing shall not apply to the Company’s or its Subsidiaries’ or other Representatives’ willful misconduct or gross negligence.

          Section 6.19 Dividend Matters. If the Company has declared and set a record date for a regular quarterly cash dividend payable to the Company’s stockholders for the quarter ended prior to the quarter in which the Effective Time occurs (the “Final Full Quarterly Dividend”), and the Effective Time occurs prior to the payment date for the Final Full Quarterly Dividend, then Parent or the Surviving Corporation will pay the Final Full Quarterly Dividend on behalf of the Company following the Closing on the scheduled payment date for such dividend.

          Section 6.20 No Financing Condition. For the avoidance of doubt, the obligation of Parent and Merger Sub to close the transactions contemplated by this Agreement is not conditioned upon the consummation of the Financing and, accordingly, the Parties agree that a failure of Parent and Merger Sub to close the transactions contemplated by this Agreement resulting from a failure or inability to consummate the Financing constitutes a breach for purposes of this Agreement.

          Section 6.21 Parent’s Vote at Company Stockholders Meeting. If the Company Stockholder Approval is required by applicable Law, Parent shall vote all shares of Company Common Stock beneficially owned by it or any of its Subsidiaries in favor of the Merger at the Company Stockholders Meeting.

          Section 6.22 Payment of Termination Fee. Concurrently with the termination by the Company of the Yara Merger Agreement in accordance with its terms, Parent (on behalf of the Company) shall have paid in full the Yara Termination Fee.

          Section 6.23 No Parent Shareholder Approval. Parent shall not take any action that would, or would reasonably be expected to, result in the holders of any class or series of Securities of Parent having a right to approve the Offer or the Merger or the issuance of Parent Common Stock pursuant thereto, or the Financing.

          Section 6.24 Merger Sub and Surviving Corporation Compliance. Parent shall cause Merger Sub or the Surviving Corporation, as applicable, to perform all of its respective agreements, covenants and obligations under this Agreement and Merger Sub shall not engage in any activities of any nature except as provided in or contemplated by this Agreement.

               (i) if the Company shall have breached or failed to perform any of its representations, warranties or covenants contained in this Agreement, which breach or failure to perform (A) is incapable of being cured by the Company prior to the Walk-Away Date or is not cured by the earlier of (x) forty (40) Business Days following written notice to the Company by Parent of such breach or (y) the Walk-Away Date and (B) would result in the existence of any event or condition set forth in subparagraph (b) or subparagraph (c) of Annex I, as the case may be;

               (i) if Parent or Merger Sub shall have breached or failed to perform any of its representations, warranties or covenants contained in this Agreement, which breach or failure to perform (A) is incapable of being cured by Parent or Merger Sub prior to the Walk-Away Date or is not cured by the earlier of (x) forty (40) Business Days following written notice to Parent by the Company of such breach or (y) the Walk-Away Date and (B) would result in the existence of any of the events or conditions set forth in the immediately following paragraph.

               The Company shall be entitled to deliver a written notice to Parent (a “Section 8.1(d) Notice”) if: (1) the representations and warranties of Parent and Merger Sub in Section 4.8(b) of this Agreement shall not be true and correct in all respects as of the date of this Agreement or as of immediately prior to

the Acceptance Time as though made immediately prior to the Acceptance Time, (2) the representations and warranties of Parent and Merger Sub contained in Section 4.2 and Section 4.3 of this Agreement shall not be true and correct in all material respects as of the date of this Agreement or as of immediately prior to the Acceptance Time as though made immediately prior to the Acceptance Time (other than representations and warranties that by their terms speak as of another date, which shall not be true and correct as of such date), (3) all other representations and warranties of Parent and Merger Sub set forth in ARTICLE IV of this Agreement, in each case, made as if none of such representations and warranties contained any qualifications or limitations as to “materiality” or Material Adverse Effect, shall not be true and correct, in each case, as of the date of this Agreement or as of immediately prior to the Acceptance Time as though made immediately prior to the Acceptance Time (other than representations and warranties that by their terms speak as of another date, which shall not be true and correct as of such date), except where the failure of such representations and warranties to be true and correct as so made, individually or in the aggregate, does not have and is not reasonably expected to result in a Material Adverse Effect on Parent or (4) each of Parent and Merger Sub shall not have performed or complied in all material respects with all agreements and covenants required to be performed by it under this Agreement at or prior to the Acceptance Time; or

               (ii) in accordance with the terms and subject to the conditions of Section 6.5(c).

          Section 8.2 Effect of Termination.

               (a) In the event of any termination of this Agreement as provided in Section 8.1, the obligations of the Parties hereunder shall terminate and there shall be no liability on the part of any Party hereto with respect thereto, except for the provisions of Section 2.1(c), this Section 8.2 and ARTICLE IX, each of which shall remain in full force and effect; provided, however, that no Party hereto shall be relieved or released from any liability or damages arising from a breach of any provision of this Agreement, and the aggrieved Party shall be entitled to all rights and remedies available at law or in equity, including, in the case of a breach by Parent or Merger Sub, liability to the Company for damages, determined taking into account all relevant factors including lost stockholder premium and any relevant breaches by the Company.

               (b) In the event that:

               (i) this Agreement is terminated pursuant to Section 8.1(c)(ii) or Section 8.1(d)(ii), then the Company shall (1) pay to Parent the Termination Fee and (2) reimburse Parent for the payment of the Yara Termination Fee, to the extent paid by Parent (the “Parent Reimbursement Fee”). The Company shall pay such Termination Fee and such Parent Reimbursement Fee by wire transfer of immediately available funds by the second (2nd) Business Day following such termination in the case of the termination of this Agreement pursuant to Section 8.1(c)(ii), or concurrently with such termination in the case of the termination of this Agreement pursuant to Section 8.1(d)(ii);

               (ii) this Agreement is terminated pursuant to Section 8.1(c)(i) or Section 8.1(c)(iii), then the Company shall pay to Parent, by wire transfer of immediately available funds, an amount equal to the Parent Reimbursement Fee by the second (2nd) Business Day following such termination;

               (iii) this Agreement is terminated pursuant to Section 8.1(b)(iii), Section 8.1(c)(i) (as a result of a breach by the Company of any of its covenants contained in this Agreement) or Section 8.1(c)(iii) and within six (6) months after the date of such termination, the Company enters into a definitive agreement to consummate or consummates the transactions contemplated by a Takeover Proposal, then the Company shall pay to Parent, by wire transfer of immediately available funds, an amount equal to the Termination Fee and, to the extent not previously paid, the Parent Reimbursement Fee by the second (2nd) Business Day following the earlier of the date the Company enters into a definitive agreement or consummates such transaction; provided that, for purposes of this Section 8.2(b)(iii), the term “Takeover Proposal” shall have the meaning ascribed thereto in Section 1.1, except that all references to fifteen percent (15%) shall be changed to fifty percent (50%);

               (iv) this Agreement is terminated pursuant to Section 8.1(b)(i) (provided that at the time of such termination, none of the events or conditions set forth in subsections (ii), (iii) or (iv) of the first paragraph of Annex I or subparagraph (a) of Annex I shall exist), Section 8.1(b)(iii), Section 8.1(c)(i) or Section 8.1(c)(iii) and (x) at any time after the date of this Agreement and prior to the date of termination, a Takeover Proposal shall have been publicly announced and not subsequently withdrawn (or any Person shall have publicly announced or publicly communicated an intention, whether or not conditional, to make a Takeover Proposal and such intention is not subsequently withdrawn), and (y) within eighteen (18) months after the date of such termination, the Company enters into a definitive agreement to consummate or consummates the transactions contemplated by any Takeover Proposal, then the Company shall pay to Parent, by wire transfer of immediately available funds, an amount equal to the Termination Fee and, to the extent not previously paid, the Parent Reimbursement Fee by the second (2nd) Business Day following the earlier of the date the Company enters into a definitive agreement or consummates such transaction; provided that, for purposes of this Section 8.2(b)(iv), the term “Takeover Proposal” shall have the meaning ascribed thereto in Section 1.1, except that all references to fifteen percent (15%) shall be changed to fifty percent (50%); or

               (v) this Agreement is terminated pursuant to Section 8.1(b)(i) (and at the time of such termination, any of the events or conditions set forth in subsections (ii), (iii) or (iv) of the first paragraph of Annex I or subparagraph (a) of Annex I shall exist) or Section 8.1(b)(ii) (other than due to a Restraint that results primarily from any breach or violation by the Company, any Company Subsidiary, any Affiliate of the Company or any of their respective Representatives of this Agreement, any obligation to, or right of, any third-party or any Law), then Parent shall pay to the Company the Termination Fee. Parent shall

pay such Termination Fee by wire transfer of immediately available funds concurrently with such termination, in the case of a termination by Parent, or by the second (2nd) Business Day following such termination, in the case of a termination by the Company.

               (c) Each Party agrees that the agreements contained in Section 8.2(b) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the Parties would not enter into this Agreement; accordingly, if either Parent or the Company fails promptly to pay any amounts due under Section 8.2(b) and, in order to obtain such payment, the other Party commences a suit that results in a judgment against the nonpaying Party for such amounts, the nonpaying Party shall pay interest on such amounts from the date payment of such amounts was due to the date of actual payment at the prime rate of the Bank of New York in effect on the date such payment was due, together with the costs and expenses of the other Party (including reasonable legal fees and expenses) in connection with such suit.

          Section 9.3 Interpretation. When a reference is made in this Agreement to Sections, Annexes or Schedules, such reference shall be to a Section of or an Annex or a Schedule to this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the word “include,” “includes” or “including” is used in this Agreement, it shall be deemed to be followed by the words “without limitation.” The words “hereby,” “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The words “date hereof” shall refer to the date of this Agreement. The term “or” is not exclusive. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if.” The words describing the singular number shall include the plural and vice versa and words denoting any gender shall include all genders. The Parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties and no presumption or burden of

proof shall arise favoring or disfavoring any Party by virtue of the authorship of any provisions of this Agreement.

          Section 9.4 Counterparts; Effectiveness. This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and the same instrument. This Agreement shall become effective when each Party hereto shall have received counterparts thereof signed and delivered (by telecopy or otherwise) by the other Parties hereto.

          Section 9.5 Entire Agreement; Third Party Beneficiaries.

               (a) This Agreement (including the Company Disclosure Letter, the Parent Disclosure Letter and the Annex hereto) constitutes the entire agreement, and supersedes all prior agreements and understandings, both written and oral, between the Parties with respect to the subject matter hereof and thereof.

               (b) This Agreement shall be binding upon and inure solely to the benefit of each Party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any Person not a Party to this Agreement any rights, benefits or remedies of any nature whatsoever, other than Section 6.8 (which is intended to be for the benefit of the Persons covered thereby and may be enforced by such Persons). Notwithstanding the immediately preceding sentence, following the Effective Time, the provisions of ARTICLE II relating to the payment of the Merger Consideration shall be enforceable by holders of Certificates.

          Section 9.6 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Notwithstanding the foregoing, upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

          Section 9.7 Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the Parties, in whole or in part (whether by operation of Law or otherwise), without the prior written consent of the other Parties, and any attempt to make any such assignment without such consent shall be null and void; provided, that Parent and Merger Sub may assign their rights and obligations pursuant to this Agreement to any direct or indirect wholly owned Subsidiary of Parent so long as Parent continues to remain primarily liable for all of such rights and obligations. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the Parties and their respective successors and permitted assigns.

          Section 9.8 Amendment. Subject to Section 2.3(c), this Agreement may be amended by the Parties at any time before or after approval of the matters presented in connection with the Merger by the stockholders of the Company, to the extent such approval is required by

applicable Law, but, after such approval, no amendment shall be made which by Law requires further approval by such stockholders without such further approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the Parties.

          Section 9.9 Extension; Waiver. Subject to Section 2.3(c), at any time prior to the Effective Time, the Parties may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of the other Parties, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto and (c) waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a Party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such Party. The failure of any Party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights.

          Section 9.10 GOVERNING LAW AND VENUE; WAIVER OF JURY TRIAL.

               (a) The Parties hereby irrevocably submit to the exclusive jurisdiction of the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (unless the Delaware Court of Chancery shall decline to accept jurisdiction over a particular matter, in which case, in any Delaware state or federal court within the State of Delaware, the Delaware Court of Chancery and any such other court, the “Delaware Courts”) in respect of all matters arising out of or relating to this Agreement, the interpretation and enforcement of the provisions of this Agreement, and of the documents referred to in this Agreement, and in respect of the transactions contemplated hereby, and hereby waive, and agree not to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement hereof or of any such document, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said courts or that the venue thereof may not be appropriate or that this Agreement or any such document may not be enforced in or by such courts, and the Parties hereto irrevocably agree that all claims with respect to such action or proceeding shall be heard and determined exclusively in such courts. The Company hereby agrees that it will not bring or support any action, cause of action, claim, cross-claim or third-party claim of any kind or description, whether in law or in equity, whether in contract or in tort or otherwise, against any Financing Source in any way relating to this Agreement or any of the transactions contemplated by this Agreement in any forum other than the Delaware Courts; provided that if, after commencement of any such suit, any Financing Source timely files an objection in the Delaware Court to jurisdiction (other than as to service of process), the Company may bring or support an action, cause of action, claim, cross-claim or third-party claim, against only such Financing Source, in any court that has jurisdiction over such Financing Source. The Parties hereby consent to and grant the Delaware Courts jurisdiction over the person of such Parties solely for such purpose and over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 9.2 or in such other manner as may be permitted by Law shall be valid and sufficient service thereof.

               (b) THIS AGREEMENT SHALL BE DEEMED TO BE MADE IN ACCORDANCE WITH, AND IN ALL RESPECTS SHALL BE INTERPRETED, CONSTRUED AND GOVERNED BY AND IN ACCORDANCE WITH, THE LAW OF THE STATE OF DELAWARE WITHOUT REGARD TO ITS RULES OF CONFLICTS OF LAW TO THE

EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY, EXCEPT FOR SUCH PROVISIONS WHERE THE MGCL IS MANDATORILY APPLICABLE, WHICH PROVISIONS SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE MGCL; PROVIDED, HOWEVER, THAT THE MGCL SHALL GOVERN THE RELATIVE RIGHTS, OBLIGATIONS, POWERS, DUTIES AND OTHER INTERNAL AFFAIRS OF THE COMPANY AND THE BOARD OF DIRECTORS OF THE COMPANY.

               (c) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH PARTY MAKES THIS WAIVER VOLUNTARILY AND (iv) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.10(C).

          Section 9.11 Specific Enforcement. The Parties hereto agree that irreparable damage would occur in the event that any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of competent jurisdiction without proof of damages or otherwise (and each Party hereby waives any requirement for the securing or posting of any bond in connection with such remedy), this being in addition to any other remedy to which they are entitled at law or in equity. The right for specific enforcement shall include the right of the Company to cause Parent and Merger Sub to cause the Offer, the Merger and the transactions contemplated by the Merger to be consummated on the terms and subject to the conditions set forth in this Agreement. The Parties further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to Law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy. If, prior to the Walk-Away Date, any Party brings any action to enforce specifically the performance of the terms and provisions hereof by any other Party, the Walk-Away Date shall automatically be extended by (x) the amount of time during which such action is pending, plus twenty (20) Business Days or (y) such other time period established by the court presiding over such action.

          IN WITNESS WHEREOF, Parent, Merger Sub and the Company have caused this Agreement to be signed by their respective officers thereunto duly authorized, all as of the date first written above.
