At the Effective Time, by virtue of the Merger and without any action on the part of any party, each share of Merger Sub’s common stock issued and outstanding immediately prior to the Effective Time will be converted into and exchanged for one validly issued, fully paid, and nonassessable share of the Surviving Corporation’s common stock. Each stock certificate of Merger Sub evidencing ownership of any such shares will from and after the Effective Time evidence ownership of shares of the Surviving Corporation’s common stock, so that, after the Effective Time, Parent shall be the holder of all of the issued and outstanding shares of the Surviving Corporation’s common stock. Each share of Target Common Stock issued and outstanding immediately prior to the Effective Time (other than any shares of Target Common Stock that are held in the treasury of Target or held by Parent or any of its Subsidiaries, all of which shall cease to be outstanding and be canceled and none of which shall receive any payment with respect thereto) and all rights in respect thereof shall, by virtue of the Merger and without any action on the part of the holder thereof, forthwith cease to exist and be converted into and represent the right to receive an amount, in cash and shares of Parent Preferred Stock, equal to (x) $701,500,000, minus Actual Net Debt, plus or minus , as the case may be, the Actual Closing Working Capital Adjustment, plus or minus as the case may be, the Actual Closing CapEx Adjustment, minus the amount of Actual Closing Transaction Expenses (collectively, the “ Merger Consideration ”) divided by (y) the number of shares of Target Common Stock issued and outstanding immediately prior to the Effective Time (other than any shares of Target Common Stock which are held in the treasury of Target or held by Parent or any of its Subsidiaries, all of which shall cease to be outstanding and be canceled and none of which shall receive any payment with respect thereto).

For the avoidance of the doubt, for purposes of this Agreement, the Pro Rata Portion of the Target Stockholders shall be calculated as if the Specified Options were exercised for cash immediately prior to the Effective Time such that shares of Target Common Stock issuable upon the exercise thereof shall be deemed issued and outstanding as of the Effective Time and the Target Stockholders and the Specified Option holders shall receive a pro rata portion of the Merger Consideration; provided , that in determining the Pro Rata Portion of any Specified Option holder the aggregate exercise price for all such options shall be taken into consideration.

(a) At least three (3) Business Days, but not more than five (5) Business Days, prior to the Closing Date, Target shall deliver to Parent a statement (the “ Closing Estimate Statement ”) setting forth Target’s good faith estimate of (i) the amount of Net Debt of Target as of the Closing Date (the “ Estimated Net Debt ”), (ii) the amount, if any, by which the Estimated Net Debt is greater or less than the Target Net Debt (the “ Estimated Net Debt Adjustment ”), (iii) the Working Capital as of the Closing Date (the “ Estimated Working Capital ”), (iv) the amount, if any, by which the Estimated Working Capital exceeds the Working Capital Upper Limit or is less than the Working Capital Lower Limit, as the case may be (the “ Estimated Working Capital Adjustment ,” which, if the Estimated Working Capital is less than the Working Capital Lower Limit, the Estimated Working Capital Adjustment shall be deemed a negative amount, and if Estimated Working Capital is between the Working Capital Upper Limit and the Working Capital Lower Limit, the Estimated Working Capital Adjustment shall be $0.00), (v) its consolidated Capital Expenditures for the period commencing on January 1, 2008 and ending on the Closing Date (the “ Estimated CapEx Expenditures ”), (vi) the amount, if any, by which the Estimated CapEx Expenditures is greater or less than the Cumulative Adjusted Capex Budget Amount for the period commencing on January 1, 2008 and ending on the Closing Date (the “ Estimated CapEx Expenditures Adjustment ”), (vii) the amount of Transaction Expenses as of the Closing Date (the “ Estimated Transaction Expenses ”), (viii) the total number of outstanding shares of Target Common Stock, and (ix) Estimated Merger Consideration, which shall quantify in reasonable detail the foregoing amounts and calculations, and in each case shall be calculated in accordance with Section 1.1(d) of the Target Disclosure Letter.

          (b) On the Closing Date (or at such later date when a Target Stockholder surrenders such Target Stockholder’s Certificate(s)), upon surrender by a Target Stockholder to Parent of the certificate(s) representing the shares of Target Common Stock held by such Target Stockholder immediately prior to the Effective Time (each, a “ Certificate ”) and delivery of a letter of transmittal in form and substance reasonably satisfactory to Parent and the Target Stockholders Representative from each Target Stockholder who did not sign the Joinder Agreement containing the appropriate provisions of the Joinder Agreement, Parent shall pay to the Target Stockholders the Estimated Merger Consideration as follows:

     (ii) if the Estimated Merger Consideration is greater than $154,000,000, then each such Target Stockholder who has surrendered a Certificate shall receive (x) a number of shares of Parent Preferred Stock equal to (I) $154,000,000 minus the Escrowed Parent Preferred Stock Value, (II) divided by $18.00 (as adjusted for stock splits and combinations), and (III) multiplied by the Pro Rata Portion of such Target Stockholder (rounded to the nearest whole share), and (y) an amount in cash equal to (I) the Estimated Merger Consideration minus $154,000,000 minus the Escrowed Cash, and (II) multiplied by the Pro Rata Portion of such Target Stockholder.

          (c) Until so surrendered, each Certificate shall be deemed, for all corporate purposes, to evidence only the right to receive upon such surrender the Merger Consideration deliverable in respect thereof to which such Person is entitled pursuant to this Article III. No interest shall be paid or accrued in respect of such cash payments. If the Merger Consideration (or any portion thereof) is to be delivered to a Person other than the Person in whose name the Certificates surrendered in exchange therefor are registered, it shall be a condition to the payment of such portion of the Merger Consideration that the Certificates so surrendered shall be properly endorsed or accompanied by appropriate stock powers and otherwise in proper form for transfer and that the Person requesting such transfer pay to the Surviving Corporation any Transfer Taxes payable by reason of the foregoing or establish to the satisfaction of the Surviving Corporation that such Transfer Taxes have been paid or are not required to be paid.

     (ii) declaring, paying or setting aside any dividend or making any distribution other than dividends or distributions by any Subsidiary of Parent to Parent or any other wholly owned subsidiary of Parent, or splitting, combining, redeeming, reclassifying, purchasing or otherwise acquiring directly, or indirectly (other than pursuant to previously announced share buyback program), any shares of capital stock of, or other equity or voting interest in, Parent or any of its Subsidiaries except for purchases of equity held by management of Target or any of its Subsidiaries; or

     (iii) incurring any Indebtedness for borrowed money which would reasonably be expected to cause the conditions to the Debt Financing not to be satisfied.

          (b) During the period from the date of this Agreement to the Closing Date, Parent shall, and shall cause its Subsidiaries to, use all commercially reasonable efforts to, confer on a monthly basis with one or more designated representatives of Target regarding operational matters (including employee and human resources related matters) and the general status of ongoing operations.

          §7.2 Debt Financing . Parent will use all commercially reasonable efforts to (i) maintain the Debt Commitment Letter in full force and effect, and will not amend, terminate or waive any provisions under such Debt Commitment Letter, and (ii) comply, to the extent within Parent’s control, with all of the covenants of Parent in the Debt Commitment Letter and take all actions, to the extent within Parent’s control, necessary or desirable to cause all of the conditions to the funding of the financing contemplated in the Debt Commitment Letter to be satisfied as promptly as practicable following the date hereof and in coordination with the satisfaction of the other closing conditions set forth herein, including obtaining any opinions of legal counsel required by the Lenders thereunder and, to the extent within Parent’s control, assuring that there is no breach or default or event of default under any of its existing financing agreements and (iii) accept any changes in the terms and conditions of the proposed financing contemplated in the “market flex” provision of the Debt Commitment Letter or fee letter related thereto.

If the funding of the indebtedness contemplated by the Debt Commitment Letter becomes unavailable or Parent reasonably believes that such funding may not occur for any reason other than a breach by Target or Target Stockholders of any of its representations, warranties, covenants or agreements contained herein or in any Ancillary

Agreement, Parent will use all commercially reasonable efforts to obtain alternative financing on terms that are no less favorable to Parent (as determined in the reasonable judgment of Parent) than to those contained in the Debt Commitment Letter or fee letter related thereto including, for the avoidance of doubt, the “market flex”. Parent shall keep the Target reasonably informed of any material adverse developments relating to the proposed debt financing. Without limiting the generality of the foregoing, Parent shall use all commercially reasonable efforts to satisfy the closing conditions to the debt financing contemplated by the Debt Commitment Letter (or, if applicable, the alternative financing) that are within its control.

          §7.3 Indemnification of Directors and Officers . The Organizational Documents of Parent shall contain provisions no less favorable with respect to the limitation or elimination of liability and indemnification than are set forth in the Organizational Documents of Target as of the date of this Agreement (it being understood that the existing bylaws of Parent and the Second Amended and Restated Certificate of Incorporation satisfy this requirement), which provisions shall not be amended, repealed or otherwise modified for a period of six (6) years after the Closing Date in any manner that would materially adversely affect the rights thereunder of individuals who at or prior to the Effective Time were directors or officers of Target or any of its Subsidiaries. Contemporaneously with the Closing, Parent shall purchase tail insurance (the premiums of which shall be paid by Parent) covering each Person currently covered by the Target’s or its Subsidiaries’ directors’ and officers’ liability insurance policies, with respect to matters or circumstances occurring at or prior to the Closing Date, on coverage terms that are equivalent in all material respects to the coverage terms of such current insurance policies in effect for the Target and its Subsidiaries on the date of this Agreement. The provisions of this Section 7.3 are (i) intended to be for the benefit of, and shall be enforceable by, each Person entitled to indemnification under this Section 7.3, and each such Person’s heirs, legatees, representatives, successors and assigns, it being expressly agreed that such Persons shall be third-party beneficiaries of this Section 7.3 and (ii) in addition to, and not in substitution for, any other rights to indemnification that any such Person may have by contract or otherwise.

Parent shall and shall cause its Subsidiaries to permit Target and its representatives to have, after the date of execution of this Agreement, reasonable access during normal business hours, and on reasonable written advance notice, to the premises and to all the properties, books and records of Parent and each of its Subsidiaries and Parent shall cause the officers, employees, counsel, accountants, consultants and other representatives of Parent and each of its Subsidiaries to furnish Target with such financial and operating data and other information with respect to the business and properties of Parent and its Subsidiaries as Target shall from time to time reasonably request; provided , that

such investigation and assistance shall not unreasonably disrupt the operations of Parent and its Subsidiaries, or cause the loss of attorney/client privilege, Parent and its Subsidiaries shall have no obligation to provide the foregoing to Target. Any information provided, or caused to be provided, by Parent or its Subsidiaries pursuant to this Section 7.5 shall be subject to the terms of the Confidentiality Agreement.

          §7.6 Parent Stockholders Approval .

          (a) As soon as reasonably practicable following the date of this Agreement, Parent shall prepare and file with the SEC the Proxy Statement.

Parent shall use all commercially reasonable efforts to cause the Proxy Statement to be cleared by the SEC as promptly as practicable after its filing and thereafter cause the Proxy Statement to be distributed to stockholders of Parent as promptly as reasonably practicable after the Proxy Statement has been cleared by the SEC. No filing of, or amendment or supplement to, the Proxy Statement will be made by Parent, without providing Target and its counsel a reasonable opportunity to review and comment thereon. If at any time prior to Parent Stockholders Meeting any information relating to Parent or Target, or any of their respective Affiliates, directors or officers, should be discovered by Parent or Target that should be set forth in an amendment or supplement to the Proxy Statement, so that it 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, the party that discovers such information shall promptly notify the other parties hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC by Parent and, to the extent required by Law, disseminated to the stockholders of Parent. Parent shall notify Target promptly of the receipt of any comments from the SEC or the staff of the SEC and of any request by the SEC or the staff of the SEC for amendments or supplements to the Proxy Statement for additional information and shall supply Target with copies of all correspondence between Parent or any of its Representatives, on the one hand, and the SEC or the staff of the SEC, on the other hand, with respect to the Proxy Statement or the Merger.

          (b) Parent shall, as soon as practicable following the date of this Agreement, establish a record date for and promptly take any and all actions in connection therewith, and duly call, give notice of, convene and hold as soon as practicable (and, in any event, no more than forty (40) days following the distribution of the Proxy Statement to the stockholders of Parent), a meeting of its stockholders (the “ Parent Stockholders Meeting ”) solely for the purpose of obtaining the Parent Stockholders Approval. Subject to its fiduciary duties under applicable law, Parent shall (i) through its board of directors, recommend to its stockholders adoption of this Agreement, the Merger, the adoption of the Second Amended and Restated Certificate of Incorporation, and the approval of the other transactions contemplated by this Agreement and (ii) use all commercially reasonable efforts to solicit and obtain Parent Stockholders Approval.

          §7.7 Waiver of Standstill . Notwithstanding anything to the contrary contained in Section 6 of the Confidentiality Agreement, Parent hereby agrees that after the Proxy

Statement has been mailed to the stockholders of Parent, WCAS shall be permitted to purchase up to 2,000,000 shares of Parent Common Stock in the aggregate (but in any event, subject to applicable Law). At the Closing, WCAS will execute the Stockholders Agreement substantially in the form attached hereto as Exhibit C (the “ Stockholders Agreement ”). WCAS represents that all such purchases shall be made in accordance with applicable law, shall not be permitted to be made in the event WCAS is in possession of material inside information, WCAS shall continue to and shall comply with all other provisions of the Confidentiality Agreement (including the confidentiality provisions). Such purchases may be effectuated through market trades or private purchases. Two (2) Business Days prior to the Closing, Target shall deliver a certificate to Parent containing a list of each such purchase that includes the name of the acquiring Person, the number of shares acquired, the means by which such shares were acquired, the date of each such purchase, and the purchase prices paid by such Persons. After the Closing, WCAS shall notify Parent in writing within two (2) Business Days after the purchase of any securities under this Section 7.7, which notice shall contain the same information described in the immediately preceding sentence. For the avoidance of doubt, any shares acquired pursuant to this Section 7.7 shall not be counted in determining whether WCAS is entitled to nominate its directors pursuant to the Stockholders Agreement. In no event will the purchase of such shares or any damages incurred by WCAS in connection therewith be considered for purposes of the indemnification provisions of this Agreement; provided that the foregoing is not intended to limit in any manner WCAS’s rights and remedies as they exist under applicable Law or otherwise unrelated to this Agreement.

Promptly following their availability in the ordinary course of Parent’s business, Parent shall provide Target with a monthly consolidated balance sheet of Parent and its Subsidiaries for the preceding month and the related profit and loss statement, and shall cause Parent’s Chief Executive Officer and the Chief Financial Officer to be available to discuss such financial statements and the financial and operating performance of Parent as reasonably requested by Target.

          (b) In the event that any Employee is at any time after the Closing Date transferred to Parent or any Affiliate of Parent or becomes a participant in any benefit or compensation plan, program, agreement or arrangement of Parent or any of its Affiliates, Parent shall, to the extent permitted by Law and by the applicable plan, program, agreement or arrangement, cause such plan, program, agreement or arrangement to treat, for purposes of

eligibility and vesting only, the prior service of such Employee with Target or any of its Subsidiaries, to the extent such prior service is recognized under the comparable plan, program, agreement or arrangement of Target or any of its Subsidiaries, as service rendered to Parent or its Affiliates, as the case may be; provided, that in administering such plans, programs, agreements or arrangements of Parent or any of its Affiliates, Parent may cause a reduction of benefits under any such plans, programs, agreements or arrangements to the extent necessary to avoid duplication of benefits with respect to the same covered matter or years of service; and provided, further, that no credit shall be required under this sentence to the extent that such credit would require any increased benefits or other more favorable provisions to be given or made applicable to any other employees in order for any plan to satisfy any applicable law or satisfy any requirements for any intended favorable tax treatment.

          (c) Each of Parent and the Surviving Corporation shall cause its medical, dental and other welfare plans in which Employees or their dependants commence to participate after the Closing Date to (i) waive any preexisting condition limitations to the extent waived or satisfied by such Employee (or dependant) under similar plans of Target or any of its Subsidiaries for the plan year in which such participation begins, and (ii) take into account any deductible and out-of-pocket expenses incurred by such Employees and dependants under similar plans of Target or any of its Subsidiaries for the plan year in which such participation begins.

          (f) Unless Parent requests otherwise in writing, the Board of Directors of the Target shall adopt resolutions terminating, effective no later than the day prior to the Closing Date, any Employee Benefit Plan which is intended to meet the requirements of Section 401(k) of the Code, and which is sponsored, or contributed to, by the Target or any of its Subsidiaries (each, a “401(k) Plan”). At the Closing, the Target shall provide to Parent executed resolutions of the Board of Directors of the Target authorizing such termination. Notwithstanding the foregoing, Parent shall cause the 401(k) Plan to permit continued repayment of participant loan balances under the 401(k) Plan following the plan termination date but prior to the date distributions from the 401(k) Plan are permitted, or Parent’s 401(k) plan to permit the rollover to

Parent’s 401(k) plan of all 401(k) Plan account balances that include loan promissory notes prior to the receipt of the IRS determination letter.

          (g) Prior to the Closing, Target shall use commercially reasonable efforts to obtain a waiver from any disqualified persons (within the meaning of Section 280G(c) of the Code) of the amount of any payments contingent upon the execution of this Agreement or the consummation of the transactions contemplated hereby that have been, or may be, made or paid to such person (the “Payments”) sufficient to cause none of the Payments (or a portion thereof) to be, or become, subject to the deduction disallowance rules under Section 280G of the Code. Following the receipt of such waivers, Target shall submit the Payments for approval by Target’s shareholders, and provide shareholders with disclosure of such Payments, each in accordance with Section 280G(b)(5) of the Code and Treas. Reg. 1.280G-1 Q&A 7. Prior to submitting the Payments for approval by Target’s shareholders, Target shall disclose the documentation necessary to effect this Section 7.9(h), including the applicable shareholder consent, disclosure letter, and waivers, to Parent.

          §7.10 Exclusivity . Parent will not knowingly solicit during the period commencing on the date hereof and ending on the earlier of the date that is four (4) months from the date hereof and the Closing Date any proposals to acquire Parent.

          (c) Each of Parent and Target agrees to instruct their respective counsel to cooperate with each other and use all commercially reasonable efforts to facilitate and expedite the identification and resolution of any issues arising under the HSR Act and any other antitrust Laws at the earliest practicable dates.

          §8.3 Public Announcements . Neither Target nor Parent shall, nor shall any of their respective Affiliates, without the approval of the other party, issue any press releases or otherwise make any public statements with respect to the transactions contemplated by this Agreement, except as may be required by applicable Law or by obligations pursuant to any listing agreement with any national securities exchange so long as such party has used all commercially reasonable efforts to obtain the approval of the other party prior to issuing such press release or making such public disclosure.

          §8.4 Litigation Support . In the event and for so long as either party is actively contesting or defending against any Proceeding brought by a third party in connection with any fact, situation, circumstance, status, condition, activity, practice, plan, occurrence, event, incident, action, failure to act or transaction involving the Target or any of its Subsidiaries, the other party shall reasonably cooperate with the contesting or defending party and its counsel in the contest or defense, make available its personnel and provide such access to its non-privileged books and records as may be reasonably requested in connection with the contest or defense, at the sole cost and expense of the contesting or defending party (unless such contesting or defending party is entitled to indemnification therefor under Article XI, in which case, the costs and expense shall be borne by the Indemnifying Party in accordance with Article XI). Notwithstanding the foregoing, this Section 8.4 shall not apply to Proceedings with respect to which the parties are in dispute as to whether one of the parties has an obligation to provide indemnification under Article XI.

The representations, warranties and covenants contained in this Agreement or in any instrument, certificate or other writing delivered in connection with this Agreement or any other agreement contemplated thereby shall in no event be affected by any investigation, inquiry or examination made for or on behalf of any party, or the Knowledge of any party’s representatives or the acceptance by any party of any certificate or other writing delivered hereunder.

          §11.2 Indemnification . (a) Target Stockholders agree to indemnify and hold Parent and its Affiliates (including Target and its Subsidiaries) and their respective affiliates, stockholders, officers, directors, employees, agents, successors and assigns (each, a “ Parent Indemnitee ”), harmless on an after tax basis (taking into account benefits arising from the Loss) from and against any damages, losses, Liabilities, actions, costs, Taxes, deficiencies, assessments, judgments, obligations, claims of any kind, interest, penalties, fines or expenses (including reasonable attorneys’, consultants and experts’ fees and expenses and all amounts paid in investigation, defense or settlement of any of the foregoing but excluding punitive damages other than punitive damages actually paid to a third party), whether or not arising out of any claims by or on behalf of any party to this Agreement or any third-party claims (collectively, “ Losses ”), suffered, incurred or paid, directly or indirectly, through application of Target’s or Parent’s assets or otherwise, as a result of, in connection with or arising out of (i) the failure of any representation or warranty made by Target or any Target Stockholder in this Agreement (whether or not contained in Article IV) or in any Ancillary Agreement or in any instrument, certificate or writing delivered pursuant to this Agreement or any Ancillary Agreement to be true and correct in all respects as of the date of this Agreement and as of the Closing Date (without giving effect to any materiality, Material Adverse Effect or similar qualifiers contained therein, other than with respect to any materiality, Material Adverse Effect or similar qualifier contained in the Qualified Representations and Warranties); (ii) any breach by Target or any Target Stockholder of any of their respective covenants or agreements contained herein or in any Ancillary Agreement; and (iii) any claim by any third party (including Governmental Entities) against or affecting Target or any of its Subsidiaries which, if successful, would give rise to or relate to a breach of (x) any of the representations or warranties on the part of Target or any of its Subsidiaries referred to in clause (i) above, or (y) any of the covenants or agreements of Target or any of its Subsidiaries referred to in clause (ii) above. The amount of any indemnification due hereunder to Parent Indemnitee for any Losses shall be reduced to take into account any Tax benefit actually realized by Parent Indemnitee arising from the incurrence or payment of, or otherwise in respect of, such Losses. If any Parent Indemnitee actually receives any Tax benefit subsequent to an indemnification payment by a Target Stockholder hereunder, then such Parent Indemnitee shall promptly reimburse the Target Stockholder for any payment made or expense incurred by such Target Stockholder in connection with providing such indemnification up to the amount received by the Parent Indemnitee.

          (b) Parent agrees to indemnify and hold Target Stockholders and their Affiliates and their respective stockholders, officers, directors, employees, agents, successors and assigns (other than Target and its Subsidiaries) (each, a “ Target Indemnitee ”) harmless from and against Losses suffered, incurred or paid, directly or indirectly, as a result of, in connection with or arising out of (i) the failure of any representation or warranty made by Parent in this Agreement (whether or not contained in Article V) or in any instrument or other writing delivered pursuant to this Agreement to be true and correct in all respects as of the date of this Agreement and as of the Closing Date (without giving effect to any materiality, Material Adverse Effect or similar qualifiers contained therein) and (ii) any breach by Parent of any of the covenants or agreements contained herein or in any Ancillary Agreement. For the avoidance of doubt and not withstanding the representations and warranties of Parent contained in this Agreement (including Section 5.6), indemnifiable Losses of the Target Indemnitees shall not include any losses of any type of Target or any Target Stockholder relating to the purchase of Parent securities other than the Parent Preferred Shares received as Merger Consideration.

          (c) The obligations to indemnify and hold harmless pursuant to this Section 11.2 shall survive the consummation of the transactions contemplated by this Agreement for the time periods set forth in Section 11.1, except for claims for indemnification asserted prior to the end of such periods, which claims shall survive until final resolution thereof.

          (d) The obligations to indemnify and hold harmless pursuant to Section 11.2(a) and Section 11.2(b) shall be limited to an aggregate amount of $30,000,000 and no Person shall be entitled to recovery for Losses pursuant to such sections unless each individual indemnifiable Loss under such Sections exceeds $50,000 (the “ Mini-basket ”), it being understood that for purposes of determining whether an individual loss exceeds the Mini-basket, all Losses based on claims or a series of related claims arising out of similar facts or circumstances, shall be aggregated, including all indemnification claims under Section 11.2(a)(i) or 11.2(b)(i) as a result of, in connection with, or arising out of damage to units or missing units that is not disclosed in any section of the Target Disclosure Letter or Parent Disclosure Letter, respectively, or otherwise based on any other failure of the representations and warranties in Section 4.10 or Section 5.9, respectively (but, in connection with any breach of Section 4.10(b) or 5.9(b), respectively, excluding up to 500 damaged or missing units with a value not to exceed $1,500,000), and until the total amount of Losses exceeds $3,000,000 (the “ Basket Amount ”); provided , that to the extent the amount of Losses exceeds the Basket Amount, the Indemnified Party shall be entitled to recover the entire amount of Losses in excess of $1,500,000.

          (e) All claims for indemnification by Parent Indemnitees pursuant to Section 11.2(a) shall first be satisfied from the Escrow Amount and once the Escrow Amount has been paid to satisfy Parent Indemnitees’ indemnification claims or released to Target Stockholders pursuant to the Escrow Agreement, the Parent Indemnitees shall be entitled to pursue all claims for indemnification under Section 11.2(a) directly against Target Stockholders in accordance with the Joinder Agreement or letter of transmittal, as the case may be. Except as otherwise provided in the Joinder Agreement between the WCAS Stockholders and Parent, the indemnification obligations of Target Stockholders pursuant to this Article XI are several and not joint, it being understood that the receipt of each Target Stockholder’s Pro Rata Portion of the Merger Consideration is conditioned on such Target Stockholder’s execution and delivery to Parent of the letter of transmittal or counterpart to Joinder Agreement, as applicable.

          §11.3 Indemnification Procedure . (a) Within a reasonable period of time after the incurrence of any Losses by any Person entitled to indemnification pursuant to Section 11.2 hereof (an “ Indemnified Party ”), including, any claim by a third party described in Section 11.4, which might give rise to indemnification hereunder, the Indemnified Party shall deliver to the party from which indemnification is sought (the “ Indemnifying Party ”) and to the Escrow Agent, if applicable, a certificate (the “ Claim Certificate ”), which shall:

     (i) state that the Indemnified Party has paid or properly accrued Losses or anticipates that it may incur liability for Losses for which such Indemnified Party believes it is entitled to indemnification pursuant to this Agreement; and

     (ii) specify in reasonable detail (to the extent practicable) each individual item of Loss included in the amount so stated, the date such item was paid or properly accrued, the basis for any anticipated liability and the nature of the misrepresentation, breach of warranty, breach of covenant or claim to which each such item is related and the computation of the amount to which such Indemnified Party claims to be entitled hereunder.

          (b) In the event that the Indemnifying Party shall object to the indemnification of an Indemnified Party in respect of any claim or claims specified in any Claim Certificate, the Indemnifying Party shall, within ten (10) days after receipt by the Indemnifying Party of such Claim Certificate, deliver to the Indemnified Party a notice to such effect and the Indemnifying Party and the Indemnified Party shall, within the thirty (30) day period beginning on the date of receipt by the Indemnified Party of such objection, attempt in good faith to agree upon the rights of the respective parties with respect to each of such claims to which the Indemnifying Party shall have so objected. If the Indemnified Party and the Indemnifying Party shall succeed in reaching agreement on their respective rights with respect to any of such claims, the Indemnified Party and the Indemnifying Party shall promptly prepare and sign a memorandum setting forth such agreement. Should the Indemnified Party and the Indemnifying Party be unable to agree as to any particular item or items or amount or amounts, then the Indemnified Party and the Indemnifying Party shall submit such dispute to a court of competent jurisdiction. The party which receives a final judgment in such dispute shall be indemnified and held harmless for all reasonable attorney and consultant’s fees or expenses by the other party.

          (c) Claims for Losses specified in any Claim Certificate to which an Indemnifying Party shall not object in writing within ten (10) days of receipt of such Claim Certificate, claims for Losses covered by a memorandum of agreement of the nature described in Section 11.3(b), claims for Losses the validity and amount of which have been the subject of judicial determination as described in Section 11.3(b) and claims for Losses the validity and amount of which shall have been the subject of a final judicial determination, or shall have been settled with the consent of the Indemnifying Party, as described in Section 11.4, are hereinafter referred to, collectively, as “ Agreed Claims ”. Within ten (10) days of the determination of the amount of any Agreed Claims, subject to the limitations set forth in Section 11.2(d), (i) if the

Indemnified Party is a Parent Indemnitee, then the Target Stockholder Representative and Parent shall execute and deliver to the Escrow Agent a joint written instruction instructing the Escrow Agent to release to Parent (A) if the Escrowed Cash exceeds the amount of the Agreed Claim, an amount in cash equal to such Agreed Claim, or (B) if the Agreed Claim exceeds the Escrowed Cash but is lower than the Escrow Amount, the Escrowed Cash plus a number of shares of Parent Preferred Stock equal to the amount of the excess of the Agreed Claim over the Escrowed Cash, divided by the Fair Market Value, or (C) if the Agreed Claim exceeds the Escrow Amount, then the Target Stockholders shall, at the Target Stockholders’ option, (x) the number of shares of Parent Preferred Stock that divided by the Fair Market Value equals the excess of the Agreed Claim over the Escrow Amount, or (y) pay to the Parent Indemnitee in accordance with the Joinder Agreement the amount of the excess of the Agreed Claim over the Escrow Amount by wire transfer in immediately available funds to the bank account or accounts designated by the Parent Indemnitee in a notice to the Target Stockholders not less than two (2) Business Days prior to such payment or (ii) if the Indemnified Party is a Target Indemnitee, then Parent shall pay to the Target Indemnitee an amount equal to the Agreed Claim by wire transfer in immediately available funds to the bank account or accounts designated by the Target Indemnitee in a notice to Parent not less than two (2) Business Days prior to such payment.

          §11.4 Third Party Claims . If a claim by a third party is made against any Indemnified Party, and if such party intends to seek indemnity with respect thereto under this Article XI, such Indemnified Party shall promptly notify the Indemnifying Party of such claims; provided , that the failure to so notify shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent that the Indemnifying Party is actually and materially prejudiced thereby. The Indemnifying Party shall have thirty (30) days after receipt of such notice to assume the conduct and control, through counsel reasonably acceptable to the Indemnified Party at the expense of the Indemnifying Party, of the settlement or defense thereof and the Indemnified Party shall cooperate with it in connection therewith; provided , that (i) the Indemnifying Party shall permit the Indemnified Party to participate in such settlement or defense through counsel chosen by such Indemnified Party, provided that the fees and expenses of such counsel shall be borne by such Indemnified Party and (ii) the Indemnifying Party shall promptly be entitled to assume the defense of such action only to the extent the Indemnifying Party acknowledges its indemnity obligation and assumes and holds such Indemnified Party harmless from and against the full amount of any Loss resulting therefrom; provided , further , that the Indemnifying Party shall not be entitled to assume control of such defense and shall pay the fees and expenses of counsel retained by the Indemnified Party if (1) the claim for indemnification relates to or arises in connection with any criminal proceeding, action, indictment, allegation or investigation; (2) the claim seeks an injunction or equitable relief against the Indemnified Party; (3) the Indemnified Party has been advised in writing by counsel that a reasonable likelihood exists of a conflict of interest between the Indemnifying Party and the Indemnified Party; (4) the Indemnified Party reasonably believes an adverse determination with respect to the action, lawsuit, investigation, proceeding or other claim giving rise to such claim for indemnification would be detrimental to or injure the Indemnified Party’s reputation or future business prospects; (5) the amount claimed by the Indemnified Party (if such Indemnified Party is a Parent Indemnitee) exceeds the value of the shares of Parent Preferred Stock then held by the Escrow Agent or (6) upon petition by the Indemnified Party, the appropriate court rules that the Indemnifying Party failed or is failing to vigorously prosecute or defend such claim. Any Indemnified Party shall have the right to employ separate counsel in any such action or

claim and to participate in the defense thereof, but the fees and expenses of such counsel shall not be at the expense of the Indemnifying Party unless (x) the Indemnifying Party shall have failed, within a reasonable time after having been notified by the Indemnified Party of the existence of such claim as provided in the preceding sentence, to assume the defense of such claim, (y) the employment of such counsel has been specifically authorized in writing by the Indemnifying Party, which authorization shall not be unreasonably withheld, or (z) the named parties to any such action (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party and such Indemnified Party shall have been advised in writing by such counsel that there may be one or more legal defenses available to the Indemnified Party which are not available to the Indemnifying Party, or available to the Indemnifying Party the assertion of which would be adverse to the interests of the Indemnified Party. So long as the Indemnifying Party is reasonably contesting any such claim in good faith, the Indemnified Party shall not pay or settle any such claim. Notwithstanding the foregoing, the Indemnified Party shall have the right to pay or settle any such claim, provided that in such event it shall waive any right to indemnity therefor by the Indemnifying Party for such claim unless the Indemnifying Party shall have consented to such payment or settlement. If the Indemnifying Party does not notify the Indemnified Party within thirty (30) days after the receipt of the Indemnified Party’s notice of a claim of indemnity hereunder that it elects to undertake the defense thereof, the Indemnified Party shall have the right to contest, settle or compromise the claim but shall not thereby waive any right to indemnity therefor pursuant to this Agreement. The Indemnifying Party shall not, except with the consent of the Indemnified Party, enter into any settlement that is not entirely indemnifiable by the Indemnifying Party pursuant to this Article XI and does not include as an unconditional term thereof the giving by the Person or Persons asserting such claim to all Indemnified Parties of an unconditional release from all liability with respect to such claim or consent to entry of any judgment.

          §11.5 Calculation of Indemnity Payments . Any Person seeking indemnification under this Article XI (the “ Indemnitee ”) agrees to use all commercially reasonable efforts to pursue and collect on any material recovery available under any insurance policies; provided , however , that the Indemnitee shall not be obligated to make such insurance claim if the cost of pursuing such insurance claim together with any corresponding increase in insurance premiums or other chargebacks would exceed the value of the claim for which the Indemnitee is seeking indemnification. The amount of Losses payable under this Article XI by any Person from which any Indemnitee is seeking indemnification pursuant to this Article XI (the “ Indemnitor ”) shall be reduced by any and all amounts actually received by the Indemnitee under applicable insurance policies or from any other Person alleged to be responsible therefor. If the Indemnitee actually receives any amounts under applicable insurance policies or from any other Person alleged to be responsible for any Losses, subsequent to an indemnification payment by the Indemnitor, then such Indemnitee shall promptly reimburse the Indemnitor for any payment made or expense incurred by such Indemnitor in connection with providing such indemnification up to the amount received by the Indemnitee, net of any expenses incurred by such Indemnitee in collecting such amount.

          (a) The Company shall indemnify, to the fullest extent permitted by applicable Law, each holder of Registrable Securities, its officers, directors, partners, employees and agents, if any, and each Person, if any, who controls such holder within the meaning of Section 15 of the Securities Act, against all losses, claims, damages, liabilities (or proceedings in respect thereof) and expenses (under the Securities Act or common law or otherwise), joint or several, resulting from any violation by the Company of the provisions of the Securities Act or any untrue statement or alleged untrue statement of a material fact contained in any registration statement or prospectus (and as amended or supplemented if amended or supplemented) or any preliminary prospectus or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus, in light of the circumstances under which they were made) not misleading, except to the extent that such losses, claims, damages, liabilities (or proceedings in respect thereof) or expenses are caused by any untrue statement or alleged untrue statement contained in or by any omission or alleged omission from information concerning any holder of Registrable Securities furnished in writing to the Company by such holder expressly for use therein. No action or failure to act on the part of the underwriters (whether or not such underwriter is an Affiliate of any holder of Registrable Securities) shall affect the obligations of the Company to indemnify any holder of Registrable Securities or any other Person pursuant to the preceding sentence. In connection with any underwritten offering pursuant to Section 3.2, the Company agrees to enter into an underwriting agreement in customary form with the applicable underwriters, and the Company agrees to indemnify such underwriters, their officers, directors, employees and agents, if any, and each Person, if any, who controls such underwriters within the meaning of Section 15 of the Securities Act to the same extent as herein before provided with respect to the indemnification of the holders of Registrable Securities; provided that the Company shall not be required to indemnify any such underwriter, or any officer, director or employee of such underwriter or any Person who controls such underwriter within the meaning of Section 15 of the Securities Act, to the extent that the loss, claim, damage, liability (or proceedings in respect thereof) or expense for which indemnification is claimed results from such underwriter’s failure to send or give a copy of an amended or supplemented final prospectus to the Person asserting an untrue statement or alleged untrue statement or omission or alleged omission at or prior to the written confirmation of the sale of Registrable Securities to such Person if such statement or omission was corrected in such amended or supplemented final prospectus prior to such written confirmation and the underwriter was provided with such amended or supplemented final prospectus.

          (b) In connection with any registration statement in connection with an offering in which a holder of Registrable Securities is participating, each such holder, severally and not jointly, shall indemnify, to the fullest extent permitted by applicable Law, the Company, each underwriter and their respective officers, directors, employees and agents, if any, and each Person, if any, who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act, against any losses, claims, damages, liabilities (or proceedings in respect thereof) and expenses resulting from any untrue statement or alleged untrue statement of a material fact, or any omission or alleged omission of a material fact required to be stated in the registration statement or prospectus or preliminary prospectus or any amendment thereof or supplement thereto or necessary to make the statements therein (in the case of any prospectus, in light of the circumstances under which they were made) not misleading, but only to the extent that such untrue statement is contained in or such omission is from information so concerning a holder furnished in writing by such holder expressly for use therein; provided that such holder’s obligations hereunder shall be limited to an amount equal to the net proceeds to such holder of the Registrable Securities sold pursuant to such registration statement.

          (c) Any Person entitled to indemnification under the provisions of this Section 3.5 shall (i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim, with counsel reasonably satisfactory to the indemnified party; and if such defense is so assumed, such indemnifying party shall not enter into any settlement without the consent of the indemnified party if such settlement attributes liability to the indemnified party and such indemnifying party shall not be subject to any liability for any settlement made without its consent (which shall not be unreasonably withheld); and any underwriting agreement entered into with respect to any registration statement provided for under this Article III shall so provide. In the event an indemnifying party shall elect not to assume the defense of a claim, such indemnifying party shall not be obligated to pay the fees and expenses of more than one counsel or firm of counsel for all parties indemnified by such indemnifying party in respect of such claim.

          (d) If for any reason the foregoing indemnity is unavailable, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities or expenses (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party on the one hand and the indemnified party on the other or (ii) if the allocation provided by clause (i) above is not permitted by applicable Law or provides a lesser sum to the indemnified party than the amount hereinafter calculated, in such proportion as is appropriate to reflect not only the relative benefits received by the indemnifying party on the one hand and the indemnified party on the other but also the relative fault of the indemnifying party and the indemnified party as well as any other relevant equitable considerations. Notwithstanding the foregoing, no holder of Registrable Securities shall be required to contribute any amount in excess of the amount such holder would have been required to pay to an indemnified party if the indemnity under Section 3.5(b) were available. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The obligation of any Person to contribute pursuant to this Section 3.5 shall be several and not joint.

          (e) An indemnifying party shall make payments of all amounts required to be made pursuant to the foregoing provisions of this Section 3.5 to or for the account of the indemnified party from time to time promptly upon receipt of bills or invoices relating thereto or when otherwise due or payable.

          (f) The indemnity and contribution agreements contained in this Section 3.5 shall remain in full force and effect regardless of any investigation made by or on behalf of a participating holder of Registrable Securities, its officers, directors, agents or any Person, if any, who controls such holder as aforesaid, and shall survive the Transfer of Equity Securities by such holder and the termination of this Agreement for any reason.

     Section 3.6 Holdback Agreements .

          Each Stockholder agrees not to sell, make any short sale of, grant any option for the purchase of, or otherwise dispose of any securities, other than those Registrable Securities included in such Registration pursuant to Section 3.1 or 3.2(a) for the seven (7) days prior to and the ninety (90) days after the effectiveness of the registration statement pursuant to which such offering shall be made (or such longer periods as may be advised by the underwriter with respect to the applicable offering but in any event not to exceed thirty (30) days prior to and ninety (90) days after the effectiveness of such registration statement). The Company agrees that it and its executive officers will be subject to the holdback period requested by the underwriters of a Required Registration, if any, pursuant to this Section 3.6 to the extent that such underwriters determine such holdback by the Company and its executive officers is reasonably necessary for the successful offering and sale of all Registrable Securities in connection with such registration.

     Section 3.7 Availability of Information .

          The Company shall cooperate with each Stockholder who is a holder of any Registrable Securities in supplying such information as may be reasonably necessary for such holder to complete and file any information reporting forms presently or hereafter required by the SEC as a condition to the availability of an exemption from the Securities Act for the sale of any Registrable Securities.

CERTIFICATE OF DESIGNATION
OF
[CACTUS]

Pursuant to Section 151 of the General
Corporation Law of the State of Delaware

SERIES A CONVERTIBLE REDEEMABLE PARTICIPATING PREFERRED STOCK

          [CACTUS], a Delaware corporation (the “ Corporation ”), hereby certifies that the following resolution has been duly adopted by the Board of Directors of the Corporation (the “ Board ”):

          WHEREAS, pursuant to the amended and restated certificate of incorporation of the Corporation (the “ Amended and Restated Certificate of Incorporation ”), the Corporation is authorized to issue up to 20,000,000 shares of preferred stock, par value $.01 per share (the “ Preferred Stock ”), with such designations, preferences, rights and qualifications, limitations or restrictions as may be determined by the Board from time to time; and

          RESOLVED, that pursuant to the authority expressly granted to and vested in the Board by the provisions of the Amended and Restated Certificate of Incorporation, there hereby is created, out of the 20,000,000 shares of Preferred Stock authorized by Article IV of the Amended and Restated Certificate of Incorporation, a series of the Preferred Stock consisting of 8,555,556 shares, which series shall have the following powers, designations, preferences and relative, participating, optional and other special rights, and the following qualifications, limitations and restrictions:

          1. Designation . This series of Preferred Stock shall be designated as the “Series A Convertible Redeemable Participating Preferred Stock”.

          2. Authorization . The Corporation shall have the authority to issue 8,555,556 shares of the Series A Convertible Redeemable Participating Preferred Stock, par value $.01 per share, of the Corporation (the “ Series A Preferred Stock ”).

          3. Rank . The Series A Preferred Stock shall, with respect to dividend rights, rights upon a Liquidity Event, rights to any other distributions or payments with respect to capital stock, voting rights and all other rights and preferences, rank junior to each other class or series of capital stock of the Corporation (including, without limitation, any class or series of capital stock created after the date hereof which by its terms ranks senior to the Series A Preferred Stock), other than (i) in all respects all classes or series of common stock existing or created after the date hereof, (ii) with respect to any other class or series of capital stock

(including, without limitation, each class or series of capital stock created after the date hereof) which by its terms ranks junior to the Series A Preferred Stock, it shall rank senior to each such series of capital stock, (iii) with respect to dividends and voting rights, it shall rank pari passu with the Common Stock, and (iv) with respect to a distribution upon the occurrence of a Liquidity Event it shall rank senior to the Common Stock.

          4. Dividends .

          (a) Holders of record of shares of Series A Preferred Stock shall be entitled to receive when, as and if declared by the Board, out of funds legally available therefor, cash dividends payable on shares of the Series A Preferred Stock at the same time as cash dividends are paid on shares of Common Stock (and in the same manner and amount as if such shares of the Series A Preferred Stock had been converted at the Conversion Rate then in effect into shares of Common Stock at the time of such cash dividends). All dividends described in this Section 4(a) shall be payable on the date determined by the Board (a “ Dividend Payment Date ”). Such dividends shall be paid to the holders of record of shares of Series A Preferred Stock at the close of business on the date specified by the Board at the time such dividend is declared; provided , that such date shall not be more than sixty (60) days nor less than ten (10) days prior to the respective Dividend Payment Date.

          (b) All dividends paid with respect to the shares of Series A Preferred Stock pursuant to this Section 4 shall be paid pro rata to the holders of Series A Preferred Stock.

          (c) The shares of Series A Preferred Stock are subject to the same restrictions on the payment of dividends that are applicable to the shares of Common Stock, as set forth in the Senior Credit Agreement.

          5. Preference Upon a Liquidity Event .

          (a) Upon the occurrence of a Liquidity Event, each holder of shares of Series A Preferred Stock then outstanding shall be entitled to be paid out of the assets of the Corporation legally available for distribution to its stockholders, whether such assets are stated capital or surplus of any nature, a per share amount (such amount being herein referred to as the “ Series A Liquidation Preference ”) on such date equal to the greater of (i) the Original Liquidation Preference plus all declared and unpaid dividends per each share of Series A Preferred Stock and (ii) the amount such holder would be entitled to receive if each share of Series A Preferred Stock held by it were converted at the Conversion Rate then in effect into shares of Common Stock immediately prior to the occurrence of such Liquidity Event, before any payment is made to the holders of Common Stock or any other class or series of capital stock of the Corporation ranking on liquidation junior to the Series A Preferred Stock in connection with such Liquidity Event. If, upon the occurrence of any such Liquidity Event, the remaining assets of the Corporation legally available for distribution to its stockholders shall be insufficient to pay such holders the aggregate Series A Liquidation Preference then the entire remaining assets and funds of the Corporation legally available for distribution to the holders of the Series A Preferred Stock shall be allocated among, and distributed to, such holders pro rata based on the number of shares of Series A Preferred Stock then held by each such holder.

          (b) The amount distributed to the holders of the Series A Preferred Stock in connection with a transaction referred to in this Section 5 shall be the cash or the fair market value of the property, rights or other securities distributed to such holders by the Corporation or acquiring Person, as the case may be. The fair market value of property, rights or other securities shall (i) in the case of publicly traded securities, be equal to the value as calculated in accordance with the definitive agreement(s) giving effect to the Liquidity Event and, if the agreement(s) do not prescribe a means for calculating such value the value shall be equal to the volume weighted average of the securities on their principal exchange over the thirty (30) trading days immediately preceding the effective date of the Liquidity Event, or (ii) in all other cases, be determined by and in the good faith discretion of the Board; provided , however , that (x) if the Majority Holders (the “ Disputing Party ”) dispute in writing the Board’s determination of fair market value within ten (10) days of the Board’s determination of fair market value and the Disputing Party and the Board are unable to reach agreement as to the fair market value within twenty (20) days after the date the Board receives the Disputing Party’s written dispute of the Board’s determination of fair market value, the Corporation and the Disputing Party shall seek an independent appraisal of such fair market value by an independent appraiser experienced in valuing the property, rights or other securities in question and mutually agreeable to the Corporation and the Disputing Party, and the determination of such appraiser shall be final and binding upon the Corporation and the Disputing Party and (y) in connection with such appraisal, the cost and expense of such appraisal shall be borne 50% by the Corporation and 50% by the Disputing Party. Payment of all amounts (including, without limitation the amounts payable pursuant to Section 5(a) hereunder) required to be paid to the holders of the Series A Preferred Stock shall constitute a redemption in full of such Series A Preferred Stock and after the payment of such amounts, all such shares of Series A Preferred Stock shall cease to be outstanding for all purposes.

          (c) The amounts set forth above and throughout this Section 5 shall be subject to equitable adjustment whenever there shall occur a stock dividend, stock split or combination involving the Series A Preferred Stock.

          6. Voting .

          (a) Holders of record of shares of Series A Preferred Stock shall be entitled to vote, voting together with the holders of Common Stock as a single class, on all matters on which the holders of Common Stock are entitled to vote as if such shares of Series A Preferred Stock had been converted to Common Stock at the time of such vote at the Conversion Rate then in effect as set forth in Section 7(a).

          (b) In addition to the rights set forth in Section 6(a) hereof, without the affirmative vote of the Majority Holders, the Corporation may not amend this Certificate of Designation.

          7. Optional Conversion . The holders of the Series A Preferred Stock shall have conversion rights as follows (the “ Conversion Rights ”):

          (a) Right to Convert . Each share of the Series A Preferred Stock shall be convertible, at the option of the holder thereof, at any time and from time to time, and without

the payment of additional consideration by the holder thereof, into such number of fully paid and nonassessable shares of Common Stock as is determined by dividing the Original Liquidation Preference by the Conversion Price (as defined below) in effect at the time of conversion. The “ Conversion Price ” shall initially be $18.00 and shall be subject to adjustment from time to time as described below.

          (b) Fractional Shares . No fractional shares of Common Stock shall be issued upon conversion of Series A Preferred Stock. For purposes of determining the number of fractional shares of Common Stock that would be issued upon conversion of Series A Preferred Stock, the following calculation shall be performed: the aggregate number of shares of Series A Preferred Stock that a holder proposes to convert into shares of Common Stock shall be multiplied by the Conversion Rate then in effect. In lieu of issuing any fractional shares to which the holder would otherwise be entitled based on the result of the foregoing calculation, the Corporation shall pay cash equal to such fraction multiplied by the then effective Conversion Price.

          (c) Mechanics of Conversion .

     (i) In order for a holder of Series A Preferred Stock to convert shares of Series A Preferred Stock into shares of Common Stock, such holder shall surrender the certificate or certificates for such shares of Series A Preferred Stock at the office of the transfer agent for Series A Preferred Stock (or at the principal office of the Corporation if the Corporation serves as its own transfer agent), together with written notice that such holder elects to convert all or any number of the shares of Series A Preferred Stock represented by such certificate or certificates. Such notice shall state such holder’s name or the names of the nominees in which such holder wishes the certificate or certificates for shares of Common Stock to be issued. If required by the Corporation, certificates surrendered for conversion shall be endorsed or accompanied by a written instrument or instruments of transfer, in form reasonably satisfactory to the Corporation, duly executed by the registered holder or his, her or its attorney duly authorized in writing. The date of receipt of such certificates and notice by the transfer agent (or by the Corporation if the Corporation serves as its own transfer agent) shall be the conversion date (“ Conversion Date ”). The Corporation shall, as soon as practicable after the Conversion Date, issue and deliver to such holder of Series A Preferred Stock, or to his, her or its nominees, a certificate or certificates for the number of shares of Common Stock to which such holder shall be entitled, together with cash in lieu of any fraction of a share.

     (ii) The Corporation shall at all times when Series A Preferred Stock shall be outstanding, reserve and keep available out of its authorized but unissued Common Stock, for the purpose of effecting the conversion of Series A Preferred Stock, such number of its duly authorized shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of Series A Preferred Stock.

     (iii) Upon any such conversion, no adjustment to the applicable Conversion Price shall be made for any declared but unpaid dividends on Series A Preferred Stock surrendered for conversion or on the Common Stock delivered upon conversion.

     (iv) All shares of Series A Preferred Stock which shall have been surrendered for conversion as herein provided shall no longer be deemed to be outstanding and all rights with respect to such shares shall immediately cease and terminate on the date that such holder of Series A Preferred Stock becomes the record holder of the shares of Common Stock received upon conversion, except only the right of the holders thereof to receive shares of Common Stock in exchange therefor and the payment of any dividends declared but unpaid thereon. Any shares of Series A Preferred Stock so converted shall be retired and cancelled and shall not be reissued, and the Corporation (without the need for stockholder action) may from time to time take such appropriate action as may be necessary to reduce the authorized number of shares of Series A Preferred Stock accordingly.

     (v) The Corporation shall pay any and all issue and other taxes that may be payable in respect of any issuance or delivery of shares of Common Stock upon conversion of shares of Series A Preferred Stock pursuant to this Section 7. The Corporation shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of shares of Common Stock in a name other than that in which the shares of Series A Preferred Stock so converted were registered.

          (d) Adjustment for Stock Splits and Combinations . If the Corporation shall at any time or from time to time after the Original Issue Date effect a subdivision of the outstanding Common Stock, the applicable Conversion Price then in effect immediately before that subdivision shall be proportionately decreased. If the Corporation shall at any time or from time to time after the Original Issue Date combine the outstanding shares of Common Stock, the applicable Conversion Price then in effect immediately before the combination shall be proportionately increased. Any adjustment under this paragraph shall become effective at the close of business on the date the subdivision or combination becomes effective.

          (e) Adjustment for Certain Dividends and Distributions . In the event the Corporation at any time, or from time to time after the Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in additional shares of Common Stock, then and in each such event the applicable Conversion Price then in effect immediately before such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, to the amount obtained by multiplying the applicable Conversion Price then in effect by a fraction:

     (i) the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date (calculated assuming conversion of issued and outstanding shares of Series A Preferred Stock, and the exercise, exchange or conversion of all then outstanding options, warrants, or exchange or subscription rights), and

     (ii) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date (calculated assuming conversion of issued and

outstanding shares of Series A Preferred Stock, and the exercise, exchange or conversion of all then outstanding options, warrants, or exchange or subscription rights) plus the number of shares of Common Stock issuable in payment of such dividend or distribution; provided , that if such record date shall have been fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the applicable Conversion Price shall be recomputed accordingly as of the close of business on such record date and thereafter and the applicable Conversion Price shall be adjusted pursuant to this paragraph as of the time of actual payment of such dividends or distributions; and provided , further , that no such adjustment shall be made if, at the election of the Corporation, the holders of shares of Series A Preferred Stock simultaneously receive a dividend or other distribution of shares of Common Stock in a number equal to the number of shares of Common Stock as they would have received if all outstanding shares of Series A Preferred Stock had been converted into Common Stock on the date of such event.

          (f) Adjustments for Other Dividends and Distributions . In the event the Corporation at any time or from time to time after the Original Issue Date shall make or issue, or fix a record date for the determination of holders of shares of Common Stock entitled to receive, a dividend or other distribution payable in securities of the Corporation other than shares of Common Stock, then and in each such event provision shall be made so that the holders of shares of Series A Preferred Stock shall receive upon conversion thereof in addition to the number of shares of Common Stock receivable thereupon, the amount of securities of the Corporation that they would have received had the Series A Preferred Stock been converted into Common Stock on the date of such event and had they thereafter, during the period from the date of such event to and including the conversion date, retained such securities receivable by them as aforesaid during such period, giving application to all adjustments called for during such period under this paragraph with respect to the rights of the holders of Series A Preferred Stock; provided , that no such adjustment shall be made if, at the election of the Corporation, the holders of shares of Series A Preferred Stock simultaneously receive a dividend or other distribution of such securities in an amount equal to the amount of such securities as they would have received if all outstanding shares of Series A Preferred Stock had been converted into Common Stock on the date of such event.

          (g) Adjustment for Reclassification, Exchange, or Substitution . If the shares of Common Stock issuable upon the conversion of shares of Series A Preferred Stock shall be changed into the same or a different number of shares of any class or classes of stock, whether by capital reorganization, reclassification, or otherwise (other than a subdivision or combination of shares or stock dividend provided for above), then and in each such event the holder of each such share of Series A Preferred Stock shall have the right thereafter to convert such share into the kind and amount of shares of stock and other securities and property receivable, upon such reorganization, reclassification, or other change, by holders of the number of shares of Common Stock into which such shares of Series A Preferred Stock might have been converted immediately prior to such reorganization, reclassification, or change, all subject to further adjustment as provided herein.

          (i) Certificate as to Adjustments . Upon the occurrence of each adjustment of the applicable Conversion Price pursuant to this Section 7, the Corporation, at its expense, shall

compute such adjustment or readjustment in accordance with the terms hereof and furnish to each holder of shares of Series A Preferred Stock a statement setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Corporation shall, upon the written request at any time of any holder of Series A Preferred Stock, furnish or cause to be furnished to such holder a similar statement setting forth (i) such adjustments and readjustments, (ii) the applicable Conversion Price then in effect, and (iii) the number of shares of Common Stock and the amount, if any, of other property which then would be received upon the conversion of such Series A Preferred Stock.

     (j) Notice of Record Date . In the event:

     (i) that the Corporation declares a dividend (or any other distribution) on its shares of Common Stock payable in shares of Common Stock or other securities of the Corporation;

     (ii) that the Corporation subdivides or combines its outstanding shares of Common Stock;

     (iii) of any reclassification of the shares of Common Stock of the Corporation (other than a subdivision or combination of its outstanding shares of Common Stock or a stock dividend or stock distribution thereon);

     (iv) of the occurrence of a Liquidity Event or the consummation of a Sale of the Company; or

     (v) that the Corporation receives a Holder Optional Redemption written election or a Holder Corporation Sale Optional Redemption written election in accordance with Section 8(a) or 8(c),

then the Corporation shall use its commercially reasonable efforts to cause to be filed at its principal office or at the office of the transfer agent of the Series A Preferred Stock, and shall cause to be mailed to the holders of Series A Preferred Stock at their last addresses as shown on the records of the Corporation or such transfer agent, at least ten (10) days prior to the date specified in (A) below or thirty (30) days before the date specified in (B) below, a notice stating

     (A) the record date of such dividend, distribution, subdivision or combination, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, subdivision or combination are to be determined or the date upon which the Holder Optional Redemption is expected to be consummated; or

     (B) the date on which such Liquidity Event is expected to occur or the date on which such Sale of the Company is expected to be consummated, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such Liquidity Event or Sale of the Company; provided , that the Corporation’s failure to provide any notice required under this Section 7(j) after

using commercially reasonable efforts shall not be deemed a default, breach or violation of this Section 7(j).

          8. Holder Optional Redemptions .

          (a) At any time after the tenth (10 ^th ) anniversary of the Original Issue Date, at the written election of the Majority Holders the Corporation shall redeem (the “ Holder Optional Redemption ”) all of the shares of Series A Preferred Stock then outstanding on the date specified in the Majority Holders’ written election (which date shall not be earlier than thirty (30) days after the date of such written election or later than ninety (90) days after the date of such written election) (such date, the “ Holder Optional Redemption Date ”) for an amount per share equal to the Series A Liquidation Preference as of the Holder Optional Redemption Date. If the funds of the Corporation legally available for the redemption of shares of Series A Preferred Stock shall be insufficient to permit the payment of the amounts due to such holders on the Holder Optional Redemption Date, then the holders of Series A Preferred Stock shall share in any legally available funds pro rata based on the number of shares of Series A Preferred Stock held by each such holder. During the Default Period, (i) the Corporation shall use commercially reasonable efforts to obtain the funds and/or make funds legally available as necessary to make the remaining payments required under this Section 8, (ii) the number of directors on the Board shall be increased by one (1) and the Majority Holders shall have the right to appoint the one (1) additional director (with such director holding office until the expiration of the Default Period) and (iii) the amount of the remaining payments required under this Section 8 shall accrue interest at a rate of ten percent (10%) per annum, compounded quarterly, until the remaining payments are paid in full. As soon as practicable after the Corporation has funds legally available therefor, the Corporation shall make the remaining payments required under this Section 8.

          (b) The closing of the Corporation’s redemption pursuant to Section 8(a) shall take place at 10:00 a.m. Central Standard time on the Holder Optional Redemption Date at the Corporation’s principal executive office or place of business. At the closing the Corporation shall pay to each holder of Series A Preferred Stock, against the Corporation’s receipt from such holder of the certificate or certificates representing the shares of such Series A Preferred Stock then held by such holder, an amount equal to the aggregate payment due pursuant to Section 8(a) for all such shares, by wire transfer of immediately available funds, or if such holder shall not have specified wire transfer instructions to the Corporation prior to the closing, by check made payable to the order of such holder; provided , that if any certificate representing the shares of Series A Preferred Stock has been lost, stolen or destroyed, such holder will execute and deliver to the Corporation an affidavit of loss in connection with such lost, stolen or destroyed certificate(s), in a form reasonably acceptable to the Corporation. If so required by the Corporation, certificates surrendered for redemption shall be endorsed or accompanied by written instrument or instruments of transfer, in form reasonably satisfactory to the Corporation, duly executed by the registered holder or by his, her or its attorney duly authorized in writing.
