2.2. Closing. The purchase and sale of the Shares contemplated by this Agreement shall be consummated at a closing (the “Closing”) at the offices of Ruskin Moscou Faltischek, P.C., 000 XXX Xxxxx, Xxxx Xxxxx, 00^xx Xxxxx, Xxxxxxxxx, Xxx Xxxx 00000. The Closing shall occur on the date hereof (the “Closing Date”). The execution and delivery of this Agreement, and the Closing hereunder, shall not be deemed legally binding until 11:59:01 pm on the Closing Date; provided, however, that at such time, the purchase and sale of the Shares shall be deemed effective for all purposes retroactive to 12:01 am on the Closing Date.

2.3. Payment of the Purchase Price and Delivery of the Shares. At the Closing (a) Purchaser shall deliver to Seller, by certified or bank cashier’s check or wire transfer, $21,110,977.66 of the Cash Consideration (subject to adjustment pursuant to Section 2.8 and 5.6), (b) Purchaser shall deliver to Seller the full Stock Consideration, (c) Purchaser shall deliver $966,093.47 (the “Escrow Fund”), which constitutes the balance of the Cash Consideration, to the Escrow Agent in accordance with Section 2.4, and (d) Seller shall deliver to Purchaser certificates evidencing the Shares duly endorsed in blank or with stock transfer powers executed by Seller in a form approved by Purchaser.

2.4. Escrow. At the Closing, the Escrow Fund will be delivered by Purchaser to, and held in escrow by Ruskin Moscou Faltischek, P.C., as security for the (i) payment by Seller of any NAV Refund Amount and (ii) the indemnity obligations of Seller set forth in Article 7. The Escrow Fund shall be subject to the terms of an Escrow Agreement substantially in the form annexed hereto as Exhibit 2.4 (the “Escrow Agreement”), which shall terminate eighteen (18) months from the Closing Date in accordance with the terms thereof.

2.5. Contingent Purchase Price. As contingent consideration for the Shares, Purchaser will pay to Seller, as described below, a three-year cumulative earnout of up to an aggregate of $4,000,000 based on the achievement of specified targets (the “Targets”) of compounded annual growth rate in EBIT (“EBIT CAGR”) of Crosstex (calculated in accordance with Schedule 2.5.2(B)) as measured against the Baseline EBIT, but subject to the terms and conditions of this Section 2.5. The additional contingent consideration (the “Contingent Purchase Price”) shall be determined and payable as follows:

2.5.1. For the purpose of computing the Contingent Purchase Price due with respect to each of the twelve-month periods ending July 31, 2006 (the “First Target Year”), July 31, 2007 (the “Second Target Year”), and July 31, 2008 (the “Third Target Year”), Purchaser will make the computations set forth in Sections 2.5.2(A) and 2.5.2(B), comparing both of the computation methods therein (the “Computation Methods”). The Computation Method yielding the higher Contingent Purchase Price to Seller for the period in question shall be the Computation Method selected with respect to such period so as to maximize the Contingent Purchase Price over the three-year period ending July 31, 2008; provided, however, that except as provided in Section 2.5.2(A)(2), in no event shall the aggregate Contingent Purchase Price payable to Seller hereunder exceed $3,666,667, plus an additional $333,333 if the test under Section 2.5.2(A)(2) is satisfied.. For the First Target Year the Computation Method set forth in Section 2.5.2(A) is the only applicable method for determining the Contingent Purchase Price.

2.5.2. The Computation Methods are as follows:

(A) Annual Computation Method.

1. Subject to Section 2.5.6, for any Target Year, if the EBIT CAGR, as measured against the Baseline EBIT, is:

i. less than 4.5% for such Target Year, the Contingent Purchase Price due to Seller for such Target Year shall be zero ($0).

ii. at least 4.5% and up to 9% for such Target Year, the Contingent Purchase Price due to Seller for such Target Year will range from $488,889 to $1,222,221, determined in accordance with Schedule 2.5.

iii. equal to or greater than 9% for such Target Year, the Contingent Purchase Price due to Seller for such Target Year will be $1,222,222.

2. Subject to Section 2.5.6, if the increase in EBIT is at least 9% for each and every Target Year, as measured against EBIT for the immediately preceding twelve month period ending July 31, then, in addition to the amount of Contingent Purchase Price otherwise payable under this Section 2.5.2, Seller shall be entitled at the end of the Third Target Year, to an additional payment of Contingent Purchase Price equal to $333,333.

(B) Cumulative Computation Method.

1. Two-Year Cumulative Computation.

For the two-year period ending July 31, 2007 (the “Two-Year Period”), subject to Section 2.5.6, the Contingent Purchase Price for the Two-Year Period shall be computed as follows under this Computation Method:

i. if the EBIT CAGR for the Two-Year Period, as measured against the Baseline EBIT (the “Two-Year CAGR”), is less than 4.5%, the Contingent Purchase Price due to Seller for the Two-Year period shall be zero ($0).

ii. if the Two-Year CAGR, as measured against the Baseline EBIT, is at least 4.5% and up to 9%, Seller will be entitled to a cumulative Contingent Purchase Price for the Two-Year Period ranging from $977,778 to $2,444,443 (inclusive of the Contingent Purchase Price, if any, paid to Seller for the First Target Year), determined in accordance with Schedule 2.5.

iii. if the Two-Year CAGR, as measured against the Baseline EBIT, is equal to or greater than 9%, Seller will be entitled to a cumulative Contingent Purchase Price for the Two-Year Period of $2,444,444 (inclusive of the Contingent Purchase Price, if any, paid to Seller for the First Target Year).

2. Three-Year Cumulative Computation.

For the three-year period ending July 31, 2008 (the “Three-Year Period”), subject to Section 2.5.6, the Contingent Purchase Price for the Three-Year Period shall be computed as follows under this Computation Method:

i. if the EBIT CAGR for the Three-Year Period, as measured against the Baseline EBIT (the “Three-Year CAGR”), is less than 4.5%, the Contingent Purchase Price due to Seller for the Three-Year Period shall be zero ($0).

ii. if the Three-Year CAGR, as measured against the Baseline EBIT, is at least 4.5% and up to 9%, Seller will be entitled to a cumulative Contingent Purchase Price for the Three-Year Period ranging from $1,466,667 to $3,666,666 (inclusive of the Contingent Purchase Price, if any, paid to Seller for the First Target Year and the Second Target Year, whether under the Annual Method or the Cumulative Method), determined in accordance with Schedule 2.5.

iii. if the Three-Year CAGR, as measured against the Baseline EBIT, is equal to or greater than 9%, Seller will be entitled to a cumulative Contingent Purchase Price for the Three-Year Period of $3,666,667 (inclusive of the Contingent Purchase Price, if any, paid to Seller for the First Target Year and the Second Target Year, whether under the Annual Method or the Cumulative Method).

2.5.3. Each of the Target Years, the Two-Year Period and the Three-Year Period is sometimes referred to herein as a “Target Period.”

2.5.4. For purposes of this Section 2.5, “EBIT” shall mean, for any Target Year, the operating income of Crosstex from continuing operations during such Target Year before provision for interest and income taxes, but after provision for those corporate expenses specific or attributable or allocable to Crosstex’s operations identified on Schedule 2.5.2(A) and reflected in the calculation of Baseline EBIT, determined in accordance with GAAP. During each Target Year, for purposes of calculating EBIT hereunder, Purchaser shall cause Crosstex to consistently follow the same accounting principles, practices, procedures and classifications (to the extent in compliance with GAAP and other Requirements of Law, but subject to Section 2.5.8) used in calculating Baseline EBIT. EBIT shall exclude income and losses from the sale or other disposition of assets not in the ordinary course of business and from transactions accounted for as extraordinary events in accordance with GAAP. Purchaser agrees to act in good faith and in a commercially reasonable manner, using historical practices consistently applied, in allocating insurance expense (the only corporate expense item to be allocated by Purchaser among its subsidiaries) for purposes of computing EBIT. Purchaser and Seller agree that the memorandum of Purchaser to Crosstex dated August 1, 2005, a copy of which has been initialed by Purchaser and Seller, reflects the intention and agreement of the parties with respect to the Contingent Purchase Price and this Section 2.5.

2.5.5. The Contingent Purchase Price shall be payable as soon as practicable following completion of Purchaser’s annual audited financial statements, but in any event within seventy five (75) days following the end of each Target Period to which such

payment relates; provided, however, that if the Target Computations (as defined in Section 2.5.7) are not accepted by Seller within said time period, the Contingent Purchase Price shall be payable five (5) days following the date the Target Computations (and Targets, if applicable) are finalized in accordance with Section 2.5.7. Notwithstanding anything else herein to the contrary, if Seller’s employment by Purchaser is terminated without cause or for Good Reason (as such terms are defined in Seller’s Employment Agreement), then, for the Target Year in which the termination occurred and each and every Target Year thereafter (if any), Purchaser shall be obligated to pay to Seller the Contingent Purchase Price that would otherwise have been payable to Seller in accordance with the terms of Section 2.5 had (a) the EBIT CAGR for such Target Year(s), as measured against the Baseline EBIT, been the higher of (i) 9% or (ii) the actual amount thereof and (b) the Gross Margin requirement under Section 2.5.6 for each of such Target Years been satisfied, whether or not Crosstex actually achieves any of the Targets or satisfied such Gross Margin requirement during such Target Year(s).

2.5.6. Subject to the last sentence of Section 2.5.5, but notwithstanding anything herein to the contrary, in no event shall a Contingent Purchase Price be payable for any Target Period (determined under the annual or cumulative method) unless Crosstex maintains a fully absorbed GAAP-based gross margin of at least 30.32% for such Target Period, as derived from the annual financial statements of Crosstex (the “Gross Margin”), which Gross Margin shall be determined on a blended basis for the Two-Year Period and Three-Year Period. Subject to Section 2.5.8, Gross Margin shall be calculated in accordance with GAAP. The parties acknowledge and agree that the Gross Margin as reflected in the Audited Financial Statements for the fiscal years ended April 30, 2003, 2004 and 2005 are 33.75%, 36.42% and 37.75%, respectively.

2.5.7. Within thirty (30) days following the end of each Target Year, Purchaser shall deliver to Seller a detailed computation of EBIT, EBIT CAGR and Gross Margin for such Target Year, as well as the Two-Year CAGR or Three-Year CAGR to the extent applicable (collectively, the “Target Computations”). During the Target Periods (and for six months thereafter), Seller and their advisors shall have reasonable access during normal business hours to the books and records of Crosstex to the extent reasonably necessary to review Purchaser’s determination of the Target Computations or to determine the periodic progress of Crosstex toward the achievement of the Targets. Within twenty (20) days of receipt of the Target Computations for a given Target Period, Seller shall give written notice to Purchaser (i) accepting the computations, or (ii) requesting that one or more of the computations be audited or reviewed for accuracy, at Seller’s own expense, by Xxxxxx Xxxxxx, CPA (if not then employed by Purchaser or an affiliate of Purchaser) or an “SEC qualified” independent accounting firm (the “Accounting Firm”), or (iii) rejecting one or more of the computations. If an audit or review is requested, the Accounting Firm shall be requested to complete the audit or review within forty-five (45) days following the request for an audit or review. Promptly following any rejection of a computation, or upon the Accounting Firm presenting its audit or review report thereon, Seller and Purchaser shall have twenty-one (21) days to agree on or negotiate a final settlement. Any claim or dispute between Seller and Purchaser with respect to this Section 2.5.7 or Section 2.5.8 that cannot be resolved within twenty-one (21) days following the commencement of good faith negotiations between the parties shall be submitted to and decided by arbitration in accordance with Section 10.17. If Seller fails to give Purchaser a notice hereunder within said ten (10) day

period, the Target Computations prepared by Purchaser for the relevant Target Period shall be deemed correct and approved in all respects by Seller. In the event an audit or review results in any changes in favor of Seller to the Target Computations for a given Target Period, which thereby result in the payment of either (i) any Contingent Purchase Price to Seller (where Purchaser’s Target Computations indicated that no Contingent Purchase Price was payable) or (ii) an increase of more than $50,000 in the amount of a Contingent Purchase Price due to Seller over the amount indicated by Purchaser’s Target Computations), then Purchaser shall be responsible for the full cost and expense of the Accounting Firm in connection with such audit or review. Notwithstanding anything to the contrary, to the extent that there is no dispute among the parties with respect to the achievement of the Target Computation, the undisputed portion of the Contingent Purchase Price shall be paid to Seller in accordance with the terms of Section 2.5. Upon Seller’s request, Purchaser shall provide reasonable verification of the insurance allocation referenced in Section 2.5.4.

2.5.8. Schedule 2.5 presents the Targets that Seller and Purchaser have agreed upon for each of the Target Periods. The parties acknowledge and agree that the basis for determining the Targets has been fully agreed to by the parties. If either (A) (i) changes in GAAP or other Requirements of Law result in the inability of Crosstex to consistently follow the same accounting principles, practices, procedures and classifications for purposes of calculating EBIT or Gross Margin or (ii) Crosstex, implements a material change in its business during the Target Periods that is approved by Purchaser (e.g., the acquisition of a business or new product line or other transaction not in the ordinary course of business), and (B) either Purchaser or Seller reasonably believe that such event will either materially facilitate or impede the ability of Seller to obtain or maximize the Contingent Purchase Price then Purchaser or Seller, as the case may be, shall give prompt notice to the other party of its desire to negotiate a change to the Targets or Gross Margin. Following delivery of such notice appropriate changes to the Targets or Gross Margin shall be negotiated in good faith by Purchaser and Seller acting promptly and reasonably so as to preserve as nearly as possible the relative economic benefits of Section 2.5. In the event that the parties fail to reach an agreement on whether a change to the Targets or Gross Margin is warranted or as to the magnitude of any such change, and either Purchaser or Seller believe that such change resulted or would result in either an excessive or deficient payment of the Contingent Purchase Price as contemplated hereunder with respect to the relative economic benefits of the parties, then the provisions for resolution of disputes under Section 2.5.7 shall apply.

Article 5

COVENANTS

5.1. Estoppel Certificates and Consents. Seller shall use reasonable efforts following the Closing to assist Purchaser and Crosstex in obtaining (without the expenditure of any funds) any and all estoppel certificates requested by Purchaser’s senior lenders from the landlords under the Leases described in Schedule 3.17, and, with respect to Leases that require the consent of the landlord thereunder for the transactions contemplated hereby, landlord consents (such consents not to be conditioned on any increased rental, other payment or consideration, reduced term, parent company guaranty, or other change of lease terms) to the transactions contemplated herein in form and substance reasonably satisfactory to Purchaser.

5.2. Conveyance of Business Assets. On or prior to the Closing Date, Seller shall have conveyed to Crosstex, by instruments of conveyance reasonably satisfactory to Purchaser, all of his right, title and interest in and to all assets (including, without limitation, the assets listed on Schedule 5.2) that he owns or in which he has an interest and which are used in the operations of the business of Crosstex, except for the excluded assets, if any, described in Schedule 5.2.

5.3. Minimum Net Asset Value.

5.3.1. As soon as practical following the date hereof, Xxxx Xxxxxxxxx, Xxxxxxxx Xxxxxxxxx, Xxxxx Xxxxxxx Xxxxxxx, Xx. and Xxxxxxx Xxxxx Xxxxxxx (collectively, the “Executives”), shall deliver to Purchaser a balance sheet of Crosstex as of July 31, 2005 in the form of Schedule 5.3 (the “NAV Balance Sheet”), which reflects the Net Asset Value of Crosstex as of July 31, 2005, together with a certification and representation signed by each of the Executives that the NAV Balance Sheet is true, correct and accurate in all material respects. Purchaser and the Executives and their respective authorized representatives, at their own expense, shall have the right to perform such audit and review procedures with respect to the NAV Balance Sheet as they may determine is necessary. The NAV Balance Sheet shall be prepared and derived from the books and records of Crosstex and calculated using the methods used to compute the Net Asset Values at October 31, 2004 and June 30, 2005. Within fifteen (15) days following its receipt of the NAV Balance Sheet, Purchaser shall advise the Executives in writing if it disputes the accuracy of the NAV Balance Sheet (and the determination of Net Asset Value set forth therein), whereupon the parties shall attempt in good faith to resolve such dispute within thirty (30) days. Purchaser and Seller acknowledge and agree that the Net Asset Value of Crosstex as of June 30, 2005 is $18,103,973. Purchaser further acknowledges that it has had full opportunity to review with the Executives, and has carefully reviewed, the Net Asset Value calculation of Crosstex as of June 30, 2005 and has had full opportunity to ask questions of the Executives in connection with the calculation thereof. Accordingly, absent fraud, Purchaser shall not dispute the accuracy of the NAV Balance Sheet to the extent it relates to any period prior to July 1, 2005. If a dispute under this Section 5.3.1 cannot be fully resolved by the parties within said thirty (30) day period, the parties shall submit the unresolved dispute for determination to a nationally recognized accounting firm to be mutually selected by Purchaser and the Executives. The accounting firm shall be requested to resolve such dispute within forty-five (45) days. The decision of the accounting firm with respect to the dispute shall be binding upon Purchaser, Seller and each of the Executives. The Executives, on the one hand, and Purchaser, on the other

hand, shall each bear 50% of the fees and expenses of such accounting firm in resolving such dispute.

5.3.2. “Net Asset Value” means: “Total Assets” less “Total Liabilities” in each case as reflected on the NAV Balance Sheet, subject to any adjustments made by the accounting firm in accordance with Section 5.3.1; provided, however, that for purposes of determining Net Asset Value hereunder, “Total Liabilities” shall exclude the Assumed Obligations. The Net Asset Value reflected on the NAV Balance Sheet will be deemed finalized upon the execution of a certificate by the Executives and Purchaser to such effect or, if disputed, the date of the resolution of the dispute by the accounting firm pursuant to Section 5.3.1. In either event, Seller and Purchaser shall give written notice to Ruskin Moscou Faltischek, P.C. (or successor escrow agent of the Escrow Fund) once the Net Asset Value is finalized that indicates the amount, if any, of the NAV Refund Amount payable to Purchaser and the amount, if any, of the Escrow Fund to be released to Seller.

5.3.3. In the event that the Net Asset Value as of July 31, 2005 (determined in accordance with Section 5.3.2) is less than $18,160,342 (the Net Asset Value as of October 31, 2004 as determined and agreed upon by Purchaser and Seller) (the amount by which the Net Asset Value is less than $18,160,342 shall be referred to as the “Shortfall”), the Purchase Price payable to Seller hereunder shall be reduced by an amount (the “NAV Refund Amount”) equal to 32.76% of the Shortfall. The NAV Refund Amount, if any, shall be paid to Purchaser within ten (10) days following the finalization of the Net Asset Value through a payment from the Escrow Fund to Purchaser equal to the NAV Refund Amount. If the Shortfall does not exceed $100,000, Seller shall be entitled to receive a payment from the Escrow Fund in an amount equal to the 32.76% of the difference between $100,000 and the Shortfall.

5.3.4 In the event that the Net Asset Value as of July 31, 2005 (determined in accordance with Section 5.3.2) is greater than $18,160,342, the Cash Consideration payable to Seller hereunder shall be increased by an amount equal to 32.76% of such excess, which shall be paid to Seller by Purchaser within ten (10) days following the finalization of the Net Asset Value. Seller hereby authorizes and directs Purchaser to deliver such payment of additional Cash Consideration, if any, to his attorneys, Ruskin Moscou Faltischek, P.C. (at the address set forth in Section 10.4), as his agent.

5.3.5 Notwithstanding anything herein to the contrary, the amount of the Bonus Pool paid under Section 2.8 ($825,000) shall be a reduction of the liability for accrued expenses for purposes of calculating Net Asset Value as of July 31, 2005.

5.3.6 Notwithstanding anything herein to the contrary, for purposes of determining Net Asset Value as of July 31, 2005, cash of Crosstex on said date shall be added to the calculation of NAV (meaning, with regard to the example of the “NAV” calculation on Schedule 5.3, cash should NOT be deleted in arriving at the NAV).

5.4. Seller’s Sale of Cantel Shares; Cantel Guaranty.

5.4.1. On the Closing Date or within ten (10) days thereafter, Seller shall have the option (subject to applicable law) of adopting a 10b5-1 trading plan (the “10b5-1 Plan”) with a single brokerage firm selected by Seller and approved by Purchaser (such approval not to be unreasonably withheld), which provides for non-discretionary sales of Cantel Shares included in the Stock Consideration held by Seller and identified by Seller for inclusion in the 10b5-1 Plan (the “Covered Shares”). The general terms of the 10b5-1 Plan are set forth on Schedule 5.4 annexed hereto. The sale, if any, of Cantel Shares under the 10b5-1 Plan shall commence on the first trading day following the Registration Statement filed under Section 5.7 being declared effective by the SEC and shall terminate on the date that is four (4) months from such effective date (the “Trading Period”).

5.4.2. If Seller adopts a 10b5-1 Plan under Section 5.4.1, he shall give Purchaser a copy of his monthly account statement that provides detailed information regarding sales of the Covered Shares under his 10b5-1 Plan. Within fifteen (15) days following Purchaser’s receipt of all of such statements covering the full Trading Period, Purchaser shall calculate with respect to Seller (without consideration for any commissions paid by Seller), the average sales price of all Covered Shares sold by Seller during the Trading Period under the 10b5-1 Plan during the Trading Period (the “Average Sales Price”). In the event Seller’s Average Sales Price for the Covered Shares sold by him under the 10b5-1 Plan is less than $17.635 per Share (the “Guaranteed Price”), Purchaser shall pay to Seller, as additional Cash Consideration for his Shares, an amount equal to the product of (A) the difference between the Guaranteed Price and the Average Sales Price and (B) the number of Covered Shares sold by the Seller under his 10b5-1 Plan. Such payment shall be paid by Purchaser within ten (10) days following the fifteen (15) day period referred to above. Notwithstanding the foregoing to the contrary, Purchaser’s obligation hereunder shall only relate to Covered Shares that are sold in accordance with the terms of the 10b5-1 Plan.

5.4.3. Seller shall be permitted to terminate his 10b5-1 Plan at any time during the Trading Period; provided, however, that if Seller elects to terminate his 10b5-1 Plan, Purchaser’s obligation to make the Stock Guaranty Payment under Section 5.4.2 shall only apply with respect to the Covered Shares sold under the 10b5-1 Plan prior to such termination (even if Seller subsequently sells additional Cantel Shares under a new 10b5-1 Plan or otherwise).

5.4.4. In the event of changes in the outstanding Cantel Shares by reason of stock dividends, split-ups, recapitalizations, exchanges of shares, reorganizations and the like, the Average Sales Price and the Guaranteed Price shall be appropriately adjusted by Purchaser so as to preserve the relative equities of the parties under this Section 5.4.

5.5. Intentionally Deleted.

5.6. Repayment of Seller Loans. At or before the Closing, Seller shall repay in full all outstanding principal and accrued and unpaid interest on the loans from Crosstex to Seller (the “Seller Loans”).

5.7. Registration Statement.

Purchaser agrees to use its best efforts to ensure that the Registration Statement will be declared effective by the SEC within forty-five (45) days following the Closing, and remain effective for a period of one year following the Closing Date. Purchaser’s obligation hereunder is subject to Seller providing such cooperation and information as is reasonably required to prepare and file the Registration Statement.

5.8. Retention of and Access To Records. After the Closing Date, Crosstex shall retain for a period consistent with Purchaser’s “company-wide” record-retention policies and practices those business and related records (the “Records”) of Crosstex delivered to Purchaser in connection with the Agreement or the transactions contemplated hereby. Purchaser shall provide Seller and Shareholders and their representatives reasonable access thereto, during normal business hours, to enable them to prepare financial statements or tax returns, or deal with tax audits or for any other similar purpose for which access to the Records shall be reasonably required (subject to applicable confidentiality obligations).

5.9 Tax Returns. After the Closing Date, if Purchaser on behalf of Crosstex elects to amend one or more Tax Returns of Crosstex with respect to any tax period ending before the Closing Date, then Seller, if requested by Purchaser, agrees (i) to cooperate fully with Purchaser and Crosstex in the preparation of such amended Tax Returns, and (ii) to sign such amended Tax Return(s) on behalf of Crosstex. All decisions with respect to such amended Tax Returns shall be made by Purchaser on behalf of Crosstex. All Taxes owing by Crosstex as reflected on such amended Tax Returns shall be the joint and several obligation of the Executives. Seller further agrees, if requested by Purchaser, to (i) cooperate fully with Purchaser and Crosstex in the preparation of all Tax Returns of Crosstex for its fiscal year ending on April 30, 2005 and for its tax period ending on or immediately prior to the Closing Date (the “To-Be-Prepared Returns”), and (ii) to sign such Returns on behalf of Crosstex.

Subject to the limitations set forth in this Article 7, from and after the Closing, Seller shall indemnify and hold harmless Purchaser and its subsidiaries, and their respective directors, officers, employees, agents, and representatives (collectively and singly, the “Indemnified Parties”) from and against any and all losses, liabilities (including punitive or exemplary damages and fines or penalties and any interest thereon), costs and expenses (including reasonable fees and disbursements of counsel selected by such Indemnified Party), claims or other obligations of any nature whatsoever (individually, a “Damage” and collectively, “Damages”) that any Indemnified Party may suffer or incur which arise out of or result from any inaccuracy in or any breach of any representation, warranty, agreement or covenant of Seller or Crosstex contained in this Agreement or in any other agreement among Purchaser, Crosstex and one or more Shareholders under which such Shareholder(s) are selling their shares of Crosstex Stock to Purchaser. Subject to Section 7.2, Purchaser has no actual knowledge of any facts or circumstances that would serve as the basis for a claim by Purchaser against any Shareholder based upon a breach of any of the representations and warranties of Seller contained in this Agreement or breach of any of any Shareholder’s covenants or agreements to be performed by any of them at or prior to Closing. Subject to Section 7.2, Purchaser shall be deemed to have waived any breach of any of Shareholder’s representations and warranties and any such covenants and agreements of which Purchaser has such actual knowledge at the Closing.

7.1.2. Subject to the limitations set forth in this Article 7, Purchaser will indemnify and hold harmless Seller, and will pay to Seller the amount of any Damages arising, directly or indirectly, from or in connection with any inaccuracy or breach of any representation,

warranty, agreement or covenant of Purchaser contained in this Agreement (or in any exhibit, schedule or certificate delivered hereunder.

7.2. Tax Indemnity.

7.2.1 Subject to the limitations set forth in this Article 7 (but regardless of whether Purchaser has actual knowledge of any facts or circumstances that would serve as the basis for a claim by Purchaser against the Seller under this Section 7.2 or against any other Shareholder(s) under the comparable provision of any agreement among Purchaser, Crosstex and one or more Shareholders under which such Shareholder(s) are selling their shares of Crosstex Stock to Purchaser), from and after the Closing, Seller shall jointly and severally indemnify and hold harmless the Indemnified Parties from and against any and all liability for Taxes owing by Crosstex and resulting from any assessment (an “Asserted Tax Liability”) by any taxing authority with respect to (A) any tax period ending on or before the Closing Date, or (B) any tax period ending after the Closing Date if (and only to the extent that) it includes a pre-Closing Date period, and also including any Damages incurred by the Indemnified Parties as a result of such Asserted Tax Liability.

7.2.2 Subject to the limitations set forth in this Article 7 (but regardless of whether Purchaser has actual knowledge of any facts or circumstances that would serve as the basis for a claim by Purchaser against the Seller under this Section 7.2 or against any other Shareholder(s) under the comparable provision of any agreement among the Purchaser, Crosstex and one or more Shareholders under which such Shareholder(s) are selling their shares of Crosstex Stock to Purchaser), from and after the Closing Seller shall jointly and severally indemnify and hold harmless the Indemnified Parties from and against any and all liability for Taxes owing by Crosstex with respect to the To-Be-Prepared Returns to the extent that such Taxes exceed the aggregate liability for Taxes attributable to such To-Be-Prepared Returns as set forth on the NAV Balance Sheet.

7.3. Duration of Indemnities. The indemnities set forth in Article 7 shall survive the Closing and shall remain in effect for twenty-four (24) months from the date of the Closing; provided, however, that the indemnities shall continue to survive, and claims may be asserted under, (A) Section 7.1 with respect to any obligation to indemnify that relates to or arises under Section 3.4, 3.10, 3.11, 3.17(c), 3.27, 3.33, and 3.34, or (B) Section 7.2, at any time on or before the date upon which the liability to which any such claim may be related is barred by all applicable statutes of limitations. Any matter concerning a claim which has been asserted hereunder which is pending or unresolved at the end of such period shall continue to be governed by the terms and conditions of this Article 7 until finally terminated or otherwise resolved.

7.4. Notification and Participation. If any claim, suit, action or proceeding is commenced by any third party which might thereafter be made the basis for a claim under this Article 7, the Indemnified Party or Seller, as the case may be, shall promptly notify the other parties in writing, providing reasonable detail of such claim; provided, however, that any failure to give such notice will not be deemed a waiver of any rights of the Indemnified Party or Seller, as the case may be, except to the extent the rights of such party are actually prejudiced. Subject to rights of or duties to any insurer or other third Person having liability therefor, the

indemnifying party shall have the right within twenty-one (21) days after receipt of such notice to assume the control of the defense, compromise or settlement of any such action, suit, proceeding, claim, liability, demand or assessment, including, at their own expense, employment of counsel; provided, however, that if the indemnifying party shall have exercised their right to assume such control, the Indemnified Parties or Seller, as the case may be, (i) may, in their sole discretion, employ counsel to represent them (in addition to counsel employed by the indemnifying party, and in the latter case, at the sole expense of the Indemnified Parties or Seller, as the case may be) in any such matter, and in such event counsel selected by the indemnifying party shall be required to reasonably cooperate with such counsel of the Indemnified Parties or Seller, as the case may be, in such defense, compromise or settlement for the purpose of informing and sharing information with the Indemnified Parties or Seller, as the case may be, and (ii) will, at their own expense, make reasonably available to the indemnifying party those employees of Purchaser or any affiliate of Purchaser whose assistance, testimony or presence is necessary to assist the indemnifying party in evaluating and in defending any such action, suit, proceeding, claim, liability, demand or assessment; provided, however, that any such access shall be conducted in such a manner as not to interfere unreasonably with the operations of the businesses of Purchaser and its affiliates. The indemnifying party shall not compromise or settle any such action, suit, proceeding, claim, liability or assessment hereunder without the consent of Purchaser, which consent shall not be unreasonably withheld or delayed, if such compromise or settlement could adversely impact the Indemnified Parties or Seller, as the case may be.

In the event a party shall have a claim against the other hereunder which does not involve a claim or demand being asserted against or sought to be collected from it by a third party, such party shall send a written notice with respect to such claim to the other party.

So long as any right to indemnification exists pursuant to this Article 7, the affected parties each agree to retain all books, records, accounts, instruments and documents reasonably related to the notice.

7.5. Certain Limitations.

7.5.1 No Damages shall be asserted by Purchaser with respect to any matter that is covered by insurance, to the extent proceeds of such insurance are paid (net of any additional costs or taxes incurred by reason of such recovery). Notwithstanding anything to the contrary herein, Seller shall have no liability to Purchaser for Damages with respect to the indemnification obligation under Sections 7.1 and 7.2 until the aggregate liability for Damages under this Agreement and any other agreement among Crosstex, Purchaser and one or more Executives pursuant to which Purchaser is acquiring stock of Crosstex on the date hereof (collectively, “Shareholder Damages”) exceeds $400,000 (the “Indemnification Threshold”); provided, however, that once the amount of the Indemnification Threshold is exceeded, the amount of the indemnification obligation to the Indemnified Parties shall include all Damages in excess of the initial $150,000 of Shareholder Damages (i.e., there is a combined one-time $150,000 “deductible” under this Agreement and any other agreement among Crosstex, Purchaser and one or more Executives pursuant to which Purchaser is acquiring stock of Crosstex on the date hereof. Notwithstanding the foregoing to the contrary, all Taxes owing by Crosstex as reflected on the amended Tax Returns referred to in Section 5.9 shall not be subject

to any Indemnification Threshold and no “deductible” shall apply with respect to such Damages (i.e., Seller shall be liable for all such Taxes, regardless of amount and without any deductible).

7.5.2 Notwithstanding anything to the contrary herein, in no event shall the maximum aggregate liability of Seller under this Article 7 and other Executives under any other agreement among Crosstex, Purchaser and one or more Executives pursuant to which Purchaser is acquiring stock of Crosstex on the date hereof (individually or in the aggregate) exceed the sum of Forty five Million ($45,000,000) Dollars (collectively, the “Liability Cap”).

7.5.3 Notwithstanding anything to the contrary contained in the Agreement, in the event Purchaser incurs Damages for which any amount shall become due to Purchaser for indemnification under this Agreement (including, without limitation, any Damages counted toward the Indemnification Threshold and/or the deductible described in Section 7.5.2), such Damages shall be reduced by the amount of the net tax benefit, if any, received by Purchaser for the fiscal year in which such Damages are incurred as a result of the payment by Purchaser of such Damages, the object being that, after computation, the payment (if any is required pursuant to this Article 7), net of the tax benefit shall equal the Damages.

7.6. Offsets. Purchaser agrees that in the event it suffers Damages subject to indemnification by Seller hereunder, Purchaser will first make a claim against the Escrow Fund pursuant to the terms of the Escrow Agreement. In the event Damages exceed the amount of the Escrow Fund, Purchaser may offset such excess amount from any Contingent Purchase Price payable to Seller in accordance with the procedures set forth in the Escrow Agreement (to the extent applicable) and subject to the limitations of Section 7.3 with respect to the duration of indemnities. The foregoing shall in no way limit Purchaser from commencing an action against Seller or pursuing other remedies available at law or in equity in connection with such “excess” Damages.

Article 8

SURVIVAL OF REPRESENTATIONS AND WARRANTIES

The representations and warranties set forth in this Agreement shall survive the Closing for a period of twenty-four (24) months; provided, however, that the representations and warranties under Sections 3.4, 3.10, 3.11, 3.17(c), 3.27, 3.33 and 3.34 shall survive until the date upon which the liability for which any claim related to a breach thereof is barred by all applicable statutes of limitations.

Article 9

NON-COMPETE

9.1. Non-Competition Covenant. In partial consideration of the Purchase Price payable to Seller for the Shares pursuant to Article 2 and as a condition for Purchaser to enter into this Agreement, Seller covenants and agrees that for a period commencing on the Closing Date and ending six (6) years thereafter, he shall not anywhere in the United States or another country where Crosstex is then conducting business, directly or indirectly, as owner, partner, joint venturer, shareholder, broker, agent, principal, trustee, licensor, or in any other capacity

whatsoever (i) engage in, become financially interested in, be employed by, render any consultation or business advice to, or have any connection with, any business, operation or Person engaged in a similar business to, or which is otherwise competitive with, any of the businesses of Crosstex, (ii) interfere with, disrupt or attempt to disrupt any then existing relationship, contractual or otherwise, with Crosstex and any of its customers, suppliers, employees, agents or other Persons with whom it deals, (iii) solicit for employment, attempt to employ or assist any other Person in employing or soliciting for employment any employee or consultant who is at that time, or was at any time during the preceding year, employed by Crosstex, or (iv) influence or attempt to influence any of the customers of Crosstex to transfer their patronage from Crosstex to any other Person. Seller shall not, without the prior written consent of Cantel, from and after the Closing, divulge, furnish or make available to any third party any financial information or other confidential information with respect to Crosstex, other than as permitted under an employment agreement entered into pursuant to Section 6.1.9 or to his professional advisors, or as compelled by law or any applicable rule or policy of any securities commission, stock exchange or like body.

Notwithstanding the foregoing, Seller shall be permitted to invest in stock, bonds, or other securities of any public corporation provided (i) such stock, bonds, or other securities are listed on any national or required exchange or have been registered under Section 12(g) of the Securities Act of 1934; and (ii) his investment does not exceed, in the case of any class of capital stock of any issuer, one (1%) percent of the issued and outstanding shares, or in the case of bonds or other securities, one (1%) percent of the aggregate principal amount thereof issued and outstanding.

9.2. Equitable Relief. Seller agrees that the remedy at law for any breach of the covenants contained in Section 9.1 would be difficult to ascertain and therefore, in the event of breach or threatened breach of any such covenants, Purchaser, in addition to any other remedy, shall have the right to enjoin Seller from any threatened or actual activities in violation thereof and Seller hereby consents and agrees that temporary and permanent injunctive relief may be granted in any proceedings that may be brought to enforce any such covenants without the necessity of proof of actual damages. If any portion of the restrictions set forth in Section 9.1 above should, for any reason whatsoever, be declared invalid by a court of competent jurisdiction, the validity or enforceability of the remainder of such restrictions shall not thereby be adversely affected. Seller hereby declares that the territorial and time limitations set forth in Section 9.1 above are reasonable and properly required for the adequate protection of Purchaser in connection with its acquisition of Crosstex under this Agreement. In the event any such territorial or time limitation is deemed to be unreasonable by a court of competent jurisdiction, the parties agree to the reduction of the territorial or time limitation to the area or period which such court shall deem reasonable.

Article 10

Each such party agrees to indemnify and save the other harmless from any claim or demand for commission or other compensation by any broker, finder, financial consultant or similar agent not so disclosed claiming to have been employed by or on behalf of such party, and to bear the cost of legal expenses incurred in defending against any such claim.

10.16. References to Dollars. All references to “$” shall mean United States dollars.

10.17. Arbitration. Any and all claims or disputes (collectively, “Claims”) between the parties with respect to Section 2.5 as to the meaning, interpretation, application or performance of such Section, including the calculation of the Contingent Purchase Price, shall be settled by arbitration, by three arbitrators, at the option of the Claimant (as defined below) in (i) New York City, New York, U.S.A. in accordance with the Commercial Arbitration Rules of the American Arbitration Association (“AAA”), and, in each case, judgment upon the award rendered by the arbitrators may be entered in any court having jurisdiction thereof. Either Seller or Purchaser may by notice to the other require the dispute to be resolved by arbitration as set forth below. Arbitration proceedings shall be commenced by the party initiating the arbitration (the “Claimant”) giving notice (the “Initiating Notice”) to the other party (the “Respondent”). The Initiating Notice must state the nature of the dispute, the amount involved, if any, and the remedy sought. The Claimant shall designate one person to act as an arbitrator, and the Respondent shall designate one person to act as an arbitrator. In the event the Respondent fails to so designate the second arbitrator within ten days of the Claimant’s designation, the second arbitrator shall be designated by the AAA. The two arbitrators so designated, within ten days after the designation of the second arbitrator, shall designate a third arbitrator or if they are unable to agree upon a third arbitrator, a third arbitrator shall be appointed by the AAA. The decision or evaluation arrived at by such arbitrators shall be binding and there shall be no appeal therefrom. Such

arbitrators shall have all the powers given to them by legislation of the State of New York respecting private arbitrations and may at any time proceed in such a manner as they may see fit on such notice as they may deem reasonable and in the absence of any party if such party fails to attend. Each of the Claimant and the Respondent (i) shall be responsible for the payment of 100% of the fees and expenses of the arbitrator designated by it or on its behalf, and (ii) 50% of the fees and expenses of the third arbitrator, if any.
