               viii) all Proceedings (including all Liabilities arising from or related thereto) arising from, related to or in connection with the Business, including those Proceedings set forth on Schedule 4(a)(viii), but excluding the Excluded Proceedings (the “Assumed Proceedings”);

               xi) all Defective Installation Losses.

          b. The assumption by Buyer of the Assumed Liabilities, the transfer thereof by Seller, and the limitations of such transfer shall in no way expand the rights or remedies of any third party against Buyer or Seller or its Affiliates as compared to the rights and remedies which such third party would have had against Seller or its Affiliates had Buyer not assumed such liabilities. Without limiting the generality of the preceding sentence, the assumption by Buyer of the Assumed Liabilities shall not create any third party beneficiary rights which are not presently granted to any party under the terms of any Contract which is expressly assumed by Buyer under the terms of this Agreement.

     5. Excluded Liabilities. Buyer shall not assume, and shall not be deemed to have assumed, the following liabilities (collectively, the “Excluded Liabilities”):

          a. any liability or obligation of the Seller arising under this Agreement;

          b. except to the extent provided in Section 12(f), any liability or obligation of the Seller or its Affiliates with respect to, or arising out of, any employee benefit plan, executive deferred compensation plan or any other plans or arrangements for the benefit of any employees

of the Seller or any such Affiliate, including the Transferred Employees (for periods prior to the Closing in the case of the Transferred Employees);

     6. Purchase Price.

          a. The purchase price for the Assets shall be:

               i) $1,000,000 payable in cash to the Seller at Closing (the “Base Purchase Price”) by wire transfer of immediately available funds to such account or accounts as Seller shall have designated prior to the Closing Date; plus

               ii) additional earn-out consideration (the “Earn-Out”) up to a maximum amount of $12,000,000 (the “Earn-Out Amount”) which shall be paid as follows:

          b. Earn-Out. In addition to the Base Purchase Price, Seller shall be entitled, to the extent not prohibited by the terms of any credit facilities in favor of Buyer with lenders (to the extent any such restrictions exist, all payments which would be payable under this section absent such restriction shall be deferred until such time as the payment thereof is not prohibited by the terms of any such credit facilities (including upon a Change of Control upon which all such deferred accrued amounts shall be paid in accordance with Section 6(b)(iv) below) and Buyer shall use commercially reasonable best efforts to remove or exclude all such restrictions from the terms of such credit facilities), to the Earn-Out Amount as provided in this Section 6(b).

               i) With respect to the calendar year ending December 31, 2009 and each calendar year thereafter until December 31, 2013 (the “Earn-Out Period”), Buyer shall pay to Seller an amount (each such amount, an “Earn-Out Payment”), equal to 25% of the sum of (a) the EBITDA of the Business during such calendar year (the “Determination Year”), and (b) the EBITDA Loss Accrual, if any. An “EBITDA Loss Accrual”, which shall only exist if aggregate EBITDA during the Calculation Period (as defined below) is less than zero, means with respect to any Determination Year, the aggregate EBITDA of the Business during the Calculation Period.

                    1) The “Calculation Period” with respect to any Determination Year shall be from January 1st of the first year of the Earn-Out Period during which EBITDA was less than zero (or, if an Earn-Out Payment was paid or accrued in a prior Determination Year (a “Payout Year”), January 1st of the first year of the Earn-Out Period during which EBITDA was less than zero following the most recent Payout Year) through December 31st of the calendar year immediately preceding the Determination Year.

                    2) For purposes of clarity, any portion of the $12,000,000 maximum Earn-Out Amount that has not (i) accrued in accordance with Section 6(b)(i) or (ii) become payable from Buyer to Seller following a Change of Control of Buyer as of the time when the final calculation of Cumulative EBITDA for the calendar year ending December 31, 2013 has been agreed upon by the Buyer and Seller shall expire and be of no further force or effect.

               ii) Computation of EBITDA. For purposes of this Agreement, “EBITDA” of the Business for any calendar year shall mean the earnings from operations before interest, taxes, depreciation and amortization, calculated as if the Business was being operated as a separate and independent entity (which for purposes of clarity shall not include any other businesses acquired by Buyer following the date hereof and all costs and expenses in connection therewith). All components of EBITDA shall be determined in accordance with US GAAP, consistently applied. In calculating EBITDA: (a) EBITDA shall be computed without regard to “extraordinary items” of gain or loss as that term shall be defined pursuant to US GAAP, (b) EBITDA shall not include any gains, Losses or profits realized from the sale of any assets other than in the Ordinary Course of Business, (c) EBITDA will be increased by the amount by which all management fees and other charges and payments made by Buyer to any of its Affiliates

exceeds $300,000 per annum, (d) no deduction shall be made for any legal, accounting or other diligence fees or expenses arising out of this Agreement, the Original Agreement or the settlement agreement between Buyer and Seller dated January 24, 2008 (the “Settlement Agreement”) or the transactions contemplated hereby or thereby, (e) EBITDA will exclude any impact from the “cumulative effect of a change in accounting principles” as that term is defined pursuant to US GAAP, (f) EBITDA will exclude any non-cash impairment charges, and (g) the purchase and sales prices of goods and services sold by the Business to Buyer or any of its Affiliates or purchased by the Business from Buyer or any of its Affiliates shall be adjusted to reflect the amounts that the Business would have realized or paid if dealing with an independent party in an arm’s-length commercial transaction. Buyer shall calculate EBITDA based upon the year-end audited financial statements of the Business and pay the Earn-out Payment, if any, to Seller no later than the 150th day of each calendar year by wire transfer of same day funds to an account designated by Seller.

               iii) [Intentionally omitted].

               iv) Change of Control. Upon any Change of Control of Buyer, Buyer shall satisfy all indebtedness permitted by Section 6(b)(vi)(4), and the remaining proceeds paid to Buyer and/or its direct or indirect (without double counting) equity holders in connection with that Change of Control and limited only to those proceeds as a result of same, shall be paid or retained as follows:

                    1) first, Buyer and/or its equity holders shall retain an amount equal to all Invested Capital;

                    2) second, Buyer and/or its equity holders shall retain an amount equal to the Minimum Return;

                    3) third, Buyer and/or its equity holders shall pay Seller all Earn-Out Payments which were otherwise accrued and payable pursuant to Section 6(b)(i), but were deferred pursuant to such section;

                    4) fourth, Buyer and/or its equity holders shall retain 50% of the remaining proceeds and pay Seller an amount equal to 50% of the remaining proceeds until Seller has been paid $12,000,000 under this Section 6(b); and

                    5) finally, 100% of the remaining proceeds shall be retained by Buyer.

               v) For purposes of this Section 6(b), the following terms have the respective meanings below:

                    1) “Invested Capital” means the aggregate amount of equity contributed to Buyer less the aggregate amount of equity distributed from Buyer to its equity holders, excluding all management fees.

                    2) “Minimum Return” means, a 20% per annum compounded return, on all Invested Capital and for purposes of clarity, includes all distributions made from Buyer to its equity holders following the date hereof other than a return of equity as set forth in Section 6(b)(v)(1).

                    3) “Change of Control” means the occurrence after the date hereof of any of (i) an acquisition after the date hereof by an individual or legal entity or “group” (as described in Rule 13d 5(b)(1) promulgated under the Exchange Act of 1934, as amended) of effective control (whether through legal or beneficial ownership of equity interests of the Buyer, by contract or otherwise) of in excess of 50% of the voting securities, limited partnership interests, general partnership interests or any other equity interests of the Buyer, (ii) the Buyer merges into or consolidates with any other Person, or any Person merges into or consolidates with the Buyer and, after giving effect to such transaction, the equity holders of the Buyer immediately prior to such transaction own less than 50% of the equity interests of the Buyer or the successor entity of such transaction, (iii) the Buyer sells, transfers, liquidates, leases or licenses its assets, as an entirety or substantially as an entirety, to another Person and the equity holders of the Buyer immediately prior to such transaction own less than 50% of the equity interests of such Person, or (iv) the execution by the Buyer of an agreement to which the Buyer is a party or by which it is bound, providing for any of the events set forth above in (i) through (iii).

               vi) Restrictions. Until such time as the Earn-Out Amount has been paid in full or the obligation to pay the Earn-Out Amount has fully expired under the terms set forth in Section 6(b)(i)(2) hereof:

                    1) the Business shall be managed and operated as a separate, stand alone entity;

                    2) without the prior written consent of Seller, which consent shall not be unreasonably withheld, there shall be no expenses imposed upon the Business by any Affiliate of Buyer, including without limitation, any corporate overhead charges, management fees, general and administrative expense allocation or charges or expenses relating to accounting, human resources, legal and compliance and information technology nor will any services or products be provided to the Business by an Affiliate of Buyer, except at rates that are at least as

favorable as the Business could obtain from third parties; provided that Buyer shall be permitted to pay a management fee of no more than $25,000 per month to an Affiliate of Buyer;

                    3) Buyer shall not (A) declare or pay any dividends, (B) make any distributions or payments to its members or to any Affiliate of Buyer or any Affiliate of a member of Buyer (including without limitation repayment of loans), (C) purchase, redeem, retire, defease or otherwise acquire for value any of its equity interests now or hereafter outstanding, (D) return any capital to its members (or the equivalent Persons thereof) as such, or (E) permit any of its subsidiaries to do any action set forth in (A), (B), (C), or (D) other than making distributions solely to Buyer; provided that Buyer may (1) pay management fees to an Affiliate of Buyer in the aggregate maximum amount of $25,000 during any month, and (2) make distributions to its members in an amount not to exceed the federal income tax liability of such members as a result of Buyer’s income, including late penalties, if any, actually incurred by such members as a result of the timing of Buyer’s tax distribution payments; and

                    4) Buyer shall not enter into any credit facility or other arrangement of any kind whatsoever which (A) restricts the payment of the amounts set forth in Section 6(b)(iv) following a Change of Control and payment in full of all amounts due under such credit facility or arrangement, (B) restricts the payment of the amounts set forth in Section 6(b)(iv)(3) and/or (4) in a different manner than the payment of the amounts set forth in Section 6(b)(iv)(1) and/or (2) following a Change of Control and payment in full of all amounts due under such credit facility or arrangement, or (C) permits Buyer to take any action prohibited by Section 6(b)(vi)(3), unless such credit facility or arrangement concurrently permits payment of all amounts accrued under Section 6(b).

          c. Allocation of Purchase Price. The Base Purchase Price and the Earn-Out shall be referred to collectively as the “Purchase Price”. Prior to Closing, the Seller shall provide to Buyer a proposed allocation of the Purchase Price plus liabilities deemed assumed (the “Tax Purchase Price”) for the sale of the Assets. The Tax Purchase Price shall be allocated using principles that are consistent with the Internal Revenue Code of 1986, as amended. Prior to Closing, the Buyer and Seller shall mutually agree on a final allocation (the “Final Allocation”) of the Tax Purchase Price, which Final Allocation will be attached hereto as Schedule 6(c). After the Closing and in respect of periods prior to January 24, 2008, the parties shall make consistent use of the allocation, fair market value and useful lives specified on Schedule 6(c) for all tax purposes and in all filings, declarations and reports with the Internal Revenue Service (“IRS”) and similar reports for state, local, or foreign purposes in respect thereof, including the reports required to be filed under Section 1060 of the Internal Revenue Code of 1986, as amended. In connection with the amendments to this Agreement made as of January 24, 2008 and the Settlement Agreement, Buyer and Seller have mutually agreed on an amended final allocation (the “Amended Final Allocation”), which is attached hereto as Schedule 6(c)(1). No later than March 15, 2008, Buyer shall prepare and deliver IRS Forms 8594 to Seller to be filed with the IRS in accordance with Schedule (6)(c) and Schedule 6(c)(1), respectively. In any proceeding related to the determination of any tax, neither Buyer nor Seller shall contend or

represent that such Final Allocation or Amended Final Allocation, as the case may be, is not a correct allocation for the applicable tax period.

In addition, neither Seller nor its Affiliates shall be prohibited from providing or participating in the ownership, management or control of a business which provides duct, duct bank, conduit and Lighting Work (build, engineer, install, maintain) or communications, satellite, energy and broadband services (including municipal WIFI, WIMAX and other wireline or wireless broadband technologies). Furthermore, Seller and its Affiliates shall not be prohibited from providing or participating in the ownership, management or control of a business which provides (i) any services outside the United States and its territories, or (ii) services to the Department of Transportation of the State of Texas which Seller and its Affiliates provide as of the Closing Date (excluding the services provided by the Business and not otherwise provided by Seller or its Affiliates). Notwithstanding the foregoing, the restrictions set forth in the preceding sentence shall not prohibit the Seller and its Affiliates from providing or participating in the ownership, management or control of a business which provides any services within the States of Arizona, Nevada, Colorado, Oklahoma, New Mexico, Missouri or Minnesota. “Lighting Work” includes lighting structures or installing/maintaining/supporting other equipment or lighting structures.

               ii) Nothing contained in this Section 11(d) shall limit or restrict the right of Seller to hold and make investments in securities of any Person that has securities listed on a national securities exchange or admitted to trading privileges thereon or actively traded in a generally recognized over-the-counter market, provided that the aggregate equity interest therein of Seller does not exceed (5%) of the outstanding shares or interests in such Person at the time of Seller’s investment therein provided that Seller does not take any active management role. Notwithstanding any provisions of this Section 11(d) to the contrary, if Seller acquires securities of any Person that is engaged in a Competing Business, Seller shall not be deemed to be in violation of this Section 11(d), provided that at the time of acquisition the Competing Business

represents less than 25% of the gross revenues of the acquired Person for the acquired Person’s most recently completed fiscal year.

               iii) From and after the date of this Agreement until the fifth anniversary of the Closing Date, Seller shall not, without the prior written approval of Buyer, directly or indirectly solicit any individual who was a non-exempt (within the meaning of the Fair Labor Standards Act) Transferred Employee to terminate his or her employment relationship with Buyer; provided, however, that the foregoing shall not apply to individuals hired as a result of the use of an independent employment agency (so long as the agency was not directed to solicit a particular individual or a class of individuals that could only be satisfied by employees of Buyer) or as a result of the use of a general solicitation (such as an advertisement) not specifically directed to employees of Buyer. From and after the date of this Agreement until the fourth anniversary of the Closing Date, Seller will not induce or seek to induce any contractor, supplier, client or customer of Buyer to terminate its relationship with Buyer in respect of the Business.

               iv) Seller recognizes and agrees that a breach by Seller of any of the covenants and agreements in this Section 11(d) could cause irreparable harm to Buyer, that Buyer’s remedies at law in the event of such breach would be inadequate, and that, accordingly, in the event of such breach a restraining order or injunction or both may be issued against Seller, in addition to any other rights and remedies that may be available to Buyer under Applicable Law. If this Section 11(d) is more restrictive than permitted by the Applicable Laws of the jurisdiction in which Buyer seeks enforcement hereof, this Section 11(d) shall be limited to the extent required to permit enforcement under such Applicable Laws.

     12. Buyer’s Covenants.

          a. Confidentiality. Buyer acknowledges and agrees that the Confidentiality Agreement dated August 21, 2006 (the “NDA”) executed by Buyer remains in full force and effect, and Buyer’s obligations thereunder remain unaffected by the execution and delivery of this Agreement; provided, however, that Seller acknowledges and agrees that Buyer has directly

or indirectly contacted and communicated with executives or other employees of the Seller and that such contacts and communications shall not constitute a breach by Buyer of the NDA.

          b. Nonsolicitation of Employees, etc. From and after the Original Agreement Date until the fifth anniversary of the Closing Date, Buyer shall not, without the prior written approval of Seller, directly or indirectly solicit any individual who is a non-exempt (within the meaning of the Fair Labor Standards Act) employee of Seller or its Affiliates to terminate his or her employment relationship with Seller or any such Affiliate; provided, however, that the foregoing shall not apply to Transferred Employees, employees of the Business as of the date hereof who are not Transferred Employees or individuals hired as a result of the use of an independent employment agency (so long as the agency was not directed to solicit a particular individual or a class of individuals that could only be satisfied by employees of Seller or its Affiliates) or as a result of the use of a general solicitation (such as an advertisement) not specifically directed to employees of Seller or its Affiliates. Buyer recognizes and agrees that a breach by Buyer of any of the covenants and agreements in this Section 12(b) could cause irreparable harm to Seller, that Seller’s remedies at law in the event of such breach would be inadequate, and that, accordingly, in the event of such breach a restraining order or injunction or both may be issued against Buyer, in addition to any other rights and remedies that may be available to Seller under Applicable Law. If this Section 12(b) is more restrictive than permitted by Applicable Laws of the jurisdiction in which Seller seeks enforcement hereof, this Section 12(b) shall be limited to the extent required to permit enforcement under such Applicable Laws.

          c. Buyer’s Due Diligence Investigation; Certain Acknowledgements.

               i) The Buyer acknowledges and agrees that the Seller has not made any representations or warranties regarding the Seller, the Business, the Assets or the operations of the Business or otherwise in connection with the transactions contemplated hereby. Without limiting the generality of the foregoing, the Buyer acknowledges and agrees that no statements or information contained in the Data Room or any presentation regarding the Business (including any management presentation or facility tour), including but not limited to any projections, forecasts and predictions, and any other estimates, data, financial information, documents, reports, statements (oral or written), summaries, abstracts, descriptions, presentations (including any management presentation or facility tour), memoranda or offering materials, is or shall be deemed to be a representation or warranty by the Seller to the Buyer, and that Buyer has not relied thereon in determining to execute this Agreement and proceed with the transactions contemplated hereby. Buyer further acknowledges and agrees that materials it has received from Seller include projections, forecasts and predictions relating to the Business; that there are uncertainties inherent in attempting to make such projections, forecasts and predictions; that Buyer is familiar with such uncertainties and is taking full responsibility for making its own evaluation of the adequacy and accuracy of all projections, forecasts, predictions and information so furnished; that Buyer shall not have any claims against Seller or its officers, directors or Affiliates with respect thereto; and that Buyer has not relied thereon. The Buyer acknowledges that no Person has been authorized by the Seller to make any representation or warranty regarding the Seller, the Business, the assets or operations of the Business or otherwise in

connection with the transactions contemplated hereby and, if made, such representation or warranty may not be relied upon as having been authorized by the Seller.

               ii) The Buyer acknowledges and agrees that it (i) has made its own inquiry and investigation into, and, based thereon, has formed an independent judgment concerning, the Seller and the Business, and (ii) has conducted such investigations of the Seller and the Business as the Buyer deems necessary to satisfy itself as to the operations and conditions thereof, and will rely solely on such investigations and inquiries. The Buyer further acknowledges and agrees that it will not at any time assert any claim against the Seller or any of its present and former directors, officers, managers, partners, shareholders, employees, agents, Affiliates, consultants, investment bankers, attorneys, advisors or representatives, or attempt to hold the Seller or any of such Persons liable, for any inaccuracies, misstatements or omissions with respect to the information furnished by Seller or such Persons concerning the Seller or the Business.

               iii) Buyer acknowledges that the Purchase Price has been negotiated based upon Buyer’s express agreement that Buyer will acquire the Business, the Assets and Assumed Liabilities in “as is” condition and on a “where is” basis, without any representation or warranty of any kind, express or implied. Further, without limiting any representation, warranty or covenant of Seller expressly set forth herein, Buyer acknowledges that it has waived and hereby waives as a condition to Closing any further due diligence reviews, inspections or examinations with respect to the Business, including without limitation with respect to engineering, environmental, title, survey, financial, operational, regulatory and legal compliance matters.

          d. Leased Assets. At the Closing, the Buyer, at its sole option and expense, shall have the option to (i) pay off, refinance or take an assignment of the leases (as legally permitted) on the vehicles and equipment of the Business, and in connection therewith shall obtain the release of the Seller for all liability under such leases or (ii) execute a sublease with the Seller on all of the leases on the vehicles and equipment of the Business consistent with the terms of Seller’s lease. As soon as practicable (but in any event within sixty (60) days) after the Closing Date, the Buyer, at its sole option and expense, shall (i) pay off, refinance or take an assignment of the leases on the other leased assets of the Business, and in connection therewith shall obtain the release of the Seller for all liability under such leases or (ii) execute a sublease with the Seller on all of the other leased assets of the Business consistent with the terms of Seller’s lease.

          e. Preservation of and Access to Certain Information; Cooperation.

               i) On and after the Closing Date, the Buyer shall preserve all books and records of the Business for a period of ten years commencing on the Closing Date, and thereafter, shall not destroy or dispose of such records without giving notice to the Seller of such

pending disposal and offering the Seller such records. In the event that the Seller has not requested such materials within ninety (90) days following the receipt of notice from the Buyer, the Buyer may proceed to destroy or dispose of any books and records of the Business.

               ii) From and after the Closing Date, the Buyer shall (a) afford the Seller and its representatives reasonable access upon reasonable prior notice during normal business hours, to all employees, officers, properties, agreements, records, books and affairs of the Buyer relating to the Business, including, without limitation, the engineering documentation library, and provide copies at Seller’s cost of such information concerning the Business as the Seller may reasonably request in connection with the preparation of any Tax Returns, any judicial, quasi-judicial, administrative, tax, audit or arbitration proceeding, the preparation of any financial statements or reports required in accordance with Applicable Law, in connection with the defense of any third party claims or in connection with the computation of the Earn-Out and (b) cooperate fully with the Seller for any proper purpose.

          f. Employment Matters. At Closing, MasTec Services, Inc. will terminate the employment of the employees listed on Schedule 12(f) (the “Transferred Employees”) and the Buyer shall immediately hire the Transferred Employees and establish and make available a group medical plan for all Transferred Employees and their dependants that is substantially similar to the group medical plan available to the Transferred Employees immediately prior to the Closing under Seller’s plan. Seller’s plan will terminate as to the Transferred Employees at the Closing. The Buyer shall credit the Transferred Employees with all service of the Transferred Employees recognized under any Employee Benefit Plan or Benefit Arrangements as service with the Buyer for purposes of eligibility to participate, vesting and levels of benefits available, under all Buyer Plans (as defined below). The Buyer shall waive any coverage waiting period, pre-existing condition and actively-at-work requirements under the Buyer’s employee benefit plans, policies, programs, or arrangements (the “Buyer Plans”) and shall provide that any expenses incurred before the Closing Date by a Transferred Employee (and his or her dependents) during the calendar year of the Closing shall be taken into account for purposes of satisfying the applicable deductible, coinsurance and maximum out-of-pocket provisions, and applicable annual and/or lifetime maximum benefit limitations of the Buyer Plans. The Buyer Plans shall not require contributions by Transferred Employees at a rate that exceeds the rate in effect for other similarly situated employees of the Buyer. Seller shall use commercially reasonable efforts to assist Buyer in its effort to hire James Fowler, Lewis Black, John Coyne and the other Transferred Employees following the Closing. Notwithstanding anything to the contrary set forth herein, under no circumstances shall Seller’s obligation pursuant to the immediately preceding sentence require Seller to expend any funds or take any actions that would otherwise disrupt the operations of Seller’s business.

Following the Closing, Buyer shall complete each of the Current Projects, including for purposes of clarity all Bonded Obligations, as expeditiously as possible in accordance with the terms of such projects and will use best efforts to collect all payments due and payable thereunder as soon as practicable

following the Closing Date. Upon completion of each Current Project, including for purposes of clarity all Bonded Obligations, Buyer shall pay in full all vendors and contractors on a timely basis and shall use best efforts to have all surety and other bonds and liens removed in connection with such projects. Buyer shall provide evidence of compliance with this Section 12(g), including copies of all payment documentation, upon the reasonable request of Seller. For purposes of clarity, all references in this Agreement to completion of Current Projects by Buyer shall mean completion to the satisfaction and written acknowledgement of the third party or parties for whom the Current Project is performed.

          h. Seller’s Intellectual Property. Following the Closing, Buyer shall not, and shall cause all of its Affiliates not to, use the Intellectual Property of the Seller other than the Acquired Intellectual Property, including without limitation: (i) ceasing and desisting from all use of the MasTec Marks and all variations thereof in any form as previously registered, licensed or used by the Seller or the Business in connection with any goods or services, or used as business names, trade names, fictitious names and any other uses, as well as all use of any of the other Intellectual Property of the Seller and its Affiliates; and (ii) removing, destroying, erasing or otherwise eliminating all references to any of the foregoing Intellectual Property from any signage and any other tangible matter, electronic displays or other depictions of any kind which are of a permanent nature and from all clothing, signs, materials, vehicles and any other tangible matter or electronic systems or media in any form owned, controlled, leased, licensed, operated, possessed or otherwise used by Buyer or any of its Affiliates.

          i. No Dividends, Distributions or Payments. Following the Closing and until such time as all Current Projects, including for purposes of clarity, all Bonded Obligations (as defined in Section 19(f)) are fully completed, Buyer shall not (A) declare or pay any dividends, (B) make any distributions or payments to its members or to any Affiliate of Buyer or any Affiliate of a member of Buyer (including without limitation repayment of loans), (C) purchase, redeem, retire, defease or otherwise acquire for value any of its equity interests now or hereafter outstanding, (D) return any capital to its members (or the equivalent Persons thereof) as such, or (E) permit any of its subsidiaries to do any action set forth in (A), (B), (C), or (D) other than making distributions solely to Buyer; provided that Buyer may (1) pay management fees to an Affiliate of Buyer in the aggregate maximum amount of $25,000 during any month, and (2) make distributions to its members in an amount not to exceed the federal income tax liability of such members as a result of Buyer’s income, including late penalties, if any, actually incurred by such members as a result of the timing of Buyer’s tax distribution payments.

          d. Termination of Indemnification. The obligations to indemnify and hold harmless a party hereto pursuant to this Section 19, shall terminate at the time the applicable representation, warranty, covenant or agreement terminates pursuant to Section 10.

          e. Procedures.

               i) If the Seller Parties shall seek indemnification pursuant to Section 19(b), the Indemnified Party shall give written notice to the Indemnifying Party promptly (and in any event within thirty (30) days) after the Indemnified Party (or, if the Indemnified Party is a corporation, any officer or employee of the Indemnified Party) becomes aware of the facts giving rise to such claim for indemnification (an “Indemnified Claim”) specifying in reasonable detail the factual basis of the Indemnified Claim, stating the amount of the Losses, if known, the method of computation thereof, containing a reference to the provision of the Agreement in respect of which such Indemnified Claim arises and demanding indemnification therefor. Notwithstanding any other provision to the contrary, the Indemnifying Party shall not be required to indemnify, defend or hold harmless any Indemnified Party against or reimburse any Indemnified Party for any Losses unless the Indemnified Party has notified the Indemnifying Party in writing in accordance with this Section 19(e) of a pending or threatened claim with respect to such matters within thirty (30) days of the Indemnifying Party becoming aware of such pending or threatened claim and within the applicable survival period set forth in Section 10. If the Indemnified Claim arises from the assertion of any claim, or the commencement of any suit, action, proceeding or Remedial Action brought by a Person that is not a party hereto (a “Third Party Claim”), any such notice to the Indemnifying Party shall be accompanied by a copy of any papers theretofore served on or delivered to the Indemnified Parry in connection with such Third Party Claim. With respect to any Third Party Claim asserted or brought prior to the Closing Date, notice of such Third Party Claim shall be deemed to have been delivered on the Closing Date.

               ii) Upon receipt of notice of a Third Party Claim from an Indemnified Party pursuant to this Section 19(e) the Indemnifying Party will be entitled to assume the defense and control of such Third Party Claim subject to the provisions of this Section 19(e). After written notice by the Indemnifying Party to the Indemnified Party of its election to assume the defense and control of a Third Party Claim, the Indemnifying Party shall not be liable to such Indemnified Party for any legal fees or expenses subsequently incurred by such Indemnified Party in connection therewith. Notwithstanding anything in this Section 19(e) to the contrary, if the Indemnifying Party does not assume defense and control of a Third Party Claim as provided in this Section 19(e), the Indemnified Party shall have the right to defend such Third Party Claim, subject to the limitations set forth in this Section 19(e), in such manner as it may deem appropriate. Whether the Indemnifying Parry or the Indemnified Party is defending and controlling any such Third Party Claim, it shall select counsel, contractors, experts and consultants of reasonable recognized standing and competence, shall take all steps necessary in the investigation, defense or settlement thereof, and shall at all times diligently and promptly pursue the resolution thereof. The party conducting the defense thereof shall at all times act as if all Losses relating to the Third Party Claim were for its own account and shall act in good faith and with reasonable prudence to minimize Losses therefrom. The Indemnified Party shall, and shall cause each of its Affiliates, directors, officers, employees, and agents to, cooperate fully with the Indemnifying Party in connection with any Third Party Claim.

               iii) Subject to the provisions of Sections 19(e)(ii) and 19(e)(iv) the Indemnifying Party shall be authorized to consent to a settlement of, or the entry of any judgment arising from, any Third Party Claims, and the Indemnified Party shall consent to a settlement of, or the entry of any judgment arising from, such Third Party Claims; provided, that the Indemnifying Party shall (a) pay or cause to be paid all amounts arising out of such settlement judgment concurrently with the effectiveness thereof; (b) shall not encumber any of the assets of any Indemnified Party or agree to any restriction or condition that would apply to such Indemnified Party or to the conduct of that party’s business; and (c) shall obtain, as a condition of any settlement or other resolution, a complete release of each Indemnified Party against any and all damages resulting from, arising out of or incurred with respect to such settlement or other resolution. Except for the foregoing, no settlement or entry of judgment in respect of any Third Party Claim shall be consented to by any Indemnifying Party or Indemnified Party without the express written consent of the other party.

               iv) In the case of the indemnification contemplated by Section 19(e)(ii), in the event that the Indemnifying Party desires to settle the matters referenced therein or consent to the entry of any judgment arising thereunder and the Indemnified Party does not wish to consent to such settlement or entry of judgment, the Indemnified Party shall have no obligation to consent to the settlement or entry of judgment provided that it agrees in writing to pay and be responsible for 100% of any Losses; provided that the Indemnified Party shall not be required to consent to any settlement or agree to be responsible for the payment of Losses thereafter incurred with respect to any matter the settlement or entry of judgment of which would require the consent of such Indemnified Party pursuant to Section 19(e)(iii). Notwithstanding the foregoing, an Indemnifying Party may, at its option and expense, participate in the defense of any Indemnified Claim.

               v) If the Indemnifying Party and the Indemnified Party are unable to agree with respect to a procedural matter arising under this Section 19(e) the Indemnifying Party and the Indemnified Party shall, within ten (10) days after notice of disagreement given by either party, agree upon a third-party referee (“Referee”), who shall be an attorney and who shall have the authority to review and resolve the disputed matter. The parties shall present their differences in writing (each party simultaneously providing to the other a copy of all documents submitted) to the Referee and shall cause the Referee promptly to review any facts, law or arguments either the Indemnifying Party or the Indemnified Party may present. The Referee shall be retained to resolve specific differences between the parties within the range of such differences. Either party may request that all discussions with the Referee by either party be in each other’s presence. The decision of the Referee shall be final and binding unless both the Indemnifying Party and the Indemnified Party agree. The parties shall share equally all costs and fees of the Referee.

               vi) If an Indemnifying Party makes any payment on an Indemnified Claim, the Indemnifying Party shall be subrogated, to the extent of such payment, to all rights and remedies of the Indemnified Party to any insurance benefits or other claims of the Indemnified Party with respect to such claim.

          f. Bonded Obligations.

               i) As a material inducement for Seller to enter into this Agreement, and not in any way limiting Buyer’s obligations to indemnify Seller for a breach of any covenant contained herein, at the Closing Buyer is executing and delivering to Seller, the General Agreement of Indemnity in the form agreed upon between Buyer and Seller (the “General Agreement of Indemnity”), pursuant to which Buyer will indemnify Seller and its Affiliates with respect to the performance and completion of the bonded obligations as set forth therein (the “Bonded Obligations”).

               ii) Following the Closing Date, Buyer and Seller shall communicate with respect to the performance and completion of the Bonded Obligations and Buyer shall afford Seller the opportunity to remedy any actual or reasonably anticipated non-performance or non-completion of any Bonded Obligation. In connection with the Bonded Obligations, Buyer shall promptly provide Seller with any information relating thereto as Seller may reasonably request including without limitation status reports pertaining to Buyer’s performance and completion thereof. For purposes of clarity, under no circumstances shall Seller have any obligation to complete any Bonded Obligation.

               iii) Until such time as all Bonded Obligations are fully completed in accordance with Section 12(g) hereof, Buyer shall provide Seller with a Chief Financial Officer’s certificate on a monthly basis, certifying that to such officer’s best knowledge after reasonable inquiry (A) Buyer’s management-prepared monthly cash flow statements, including cash

reconciliations, which shall be attached as an exhibit to such certificate, are true and correct in all material respects subject to year-end adjustments in accordance with US GAAP, and (B) Buyer has fully complied with all provisions of Sections 6(b)(vi)(3) and 12(i) hereof.

     20. Brokers and Finders. The Seller has retained Houlihan Lokey Howard & Zukin (“HLHZ”) in connection with the transactions contemplated hereby and will pay all fees and expenses charged by HLHZ. Except for HLHZ, each party represents and warrants to the other that it has not employed or retained any broker or finder in connection with the transactions contemplated by this Agreement nor has it had any dealings with any person that may entitle that person to a fee or commission from any other party hereto. Each of the parties indemnifies and holds the others harmless from and against any claim, demand, or damages whatsoever by virtue of any arrangement or commitment made by it with or to any person that may entitle such person to any fee or commission from the other parties to this Agreement.

This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, personal representatives, successors, and assigns, except that no party may assign or transfer its rights or obligations under this Agreement without the prior written consent of the other parties hereto.

          d. Entire Agreement. This Agreement, the Settlement Agreement, the Preserved Agreements, the NDA and the schedules, exhibits, certificates and other agreements to be delivered pursuant hereto constitute the entire agreement and understanding among the parties hereto with respect to the subject matter hereof and supersede all prior and contemporaneous agreements, understandings, inducements, and conditions, express or implied, oral or written, of any nature whatsoever with respect to the subject matter hereof. This Agreement may not be modified or amended other than by an agreement in writing executed by the parties. Should there be any conflict between the terms of this Agreement and the terms of the Settlement Agreement, the terms of the Settlement Agreement shall prevail.

          e. Dispute Resolution. This Agreement shall be governed by and construed in accordance with the Laws of the State of Florida applicable to contracts made and to be performed therein. Any controversy or claim arising out of or relating to this Agreement or any related agreement or any of the contemplated transactions will be settled in the following manner: (i) senior executives representing each of Seller and Buyer will meet to discuss and attempt to resolve the controversy or claim, (ii) if the controversy or claim is not resolved as contemplated by clause (i), Seller and Buyer will, by mutual consent, select an independent third party to mediate such controversy or claim, provided that such mediation will not be binding upon the parties; and (iii) if such controversy or claim is not resolved as contemplated by clauses (i) and (ii), the parties will refer any dispute hereunder (to the exclusion of a court of law) to final and binding arbitration in Miami, Florida in accordance with the then existing rules for

expedited arbitration (the “Rules”) of the American Arbitration Association (“AAA”), and judgment upon the award rendered by the arbitrators may be entered in any court having jurisdiction thereof. The law applicable to any controversy shall be the law of the State of Florida, regardless of principles of conflicts of laws. In any arbitration pursuant to this Agreement involving a dispute in excess of $500,000, the award or decision shall be rendered by a majority of the members of a Board of Arbitration consisting of three members, one of whom shall be appointed by each of the respective parties and the third of whom shall be the chairman of the panel and be appointed by mutual agreement of said two party-appointed arbitrators. In the event of failure of said two arbitrators to agree within twenty (20) days after the commencement of the arbitration proceeding upon the appointment of the third arbitrator, the third arbitrator shall be appointed by the AAA in accordance with the Rules. In the event of a dispute involving a sum equal to or less than $500,000, a single arbitrator shall be appointed by the AAA in accordance with the Rules. In the event that either party shall fail to appoint an arbitrator within ten (10) days after the commencement of the arbitration proceedings, such arbitrator and the third arbitrator shall be appointed by the AAA in accordance with the Rules. Nothing set forth above shall be interpreted to prevent the parties from agreeing in writing to submit any dispute to a single arbitrator in lieu of a three member Board of Arbitration. Upon the completion of the selection of the Board of Arbitration (or if the parties agree otherwise in writing, a single arbitrator), an award or decision shall be rendered in writing within no more than thirty (30) days. The award rendered by arbitration shall be final and binding upon the parties, and judgment upon the award may be entered in any court of competent jurisdiction in the United States. Notwithstanding the foregoing, the request by either party for preliminary or permanent injunctive relief, whether prohibitive or mandatory, shall not be subject to arbitration and shall be adjudicated only by the courts of the State of Florida located in Miami-Dade County or the U.S. District Court for the Southern District of Florida. Each of the parties to this Agreement irrevocably consents to the service of process in any action or proceeding hereunder by the mailing of copies of the notice, summons and/or complaint by registered or certified airmail, postage prepaid, to the address specified in Section 21(a). The foregoing shall not limit the rights of any party to this Agreement to serve process in any other manner permitted by Applicable Law or to obtain execution of judgment in any other jurisdiction. An arbitrator(s) or court reviewing any dispute related to this Agreement pursuant to this Section 21(e) may award reasonable costs for legal representation to a successful party and may apportion the costs of the arbitration or court costs between the parties if the arbitrator or court determines that such apportionment is reasonable, taking into account the circumstances of the case.

          f. Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM (WHETHER BASED UPON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY.

          g. Enforcement of Agreement. The parties acknowledge and agree that in the event of a breach of this Agreement, the non-breaching party would be irreparably damaged and could not be adequately compensated in all cases by monetary damages alone. Accordingly,

in addition to any other right or remedy to which the non-breaching party may be entitled, at law or in equity, it shall be entitled to enforce any provision of this Agreement by a decree of specific performance and to temporary, preliminary and permanent injunctive relief to prevent breaches or threatened breaches of any of the provisions of this Agreement, without posting any bond or other undertaking.

          h. Provisions Separable. The provisions of this Agreement are independent of and separable from each other, and no provision shall be affected or rendered invalid or unenforceable by virtue of the fact that for any reason any other or others of them may be invalid or unenforceable in whole or in part.

          i. Indulgences Not Waivers. Neither the failure nor any delay on the part of either party to exercise any right, remedy, power or privilege under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right, remedy, power, or privilege preclude any other or further exercise of the same or of any other right, remedy, power, or privilege, nor shall any waiver of any right, remedy, power, or privilege with respect to any occurrence be construed as a waiver of such right, remedy, power, or privilege with respect to any other occurrence. No waiver shall be effective unless it is in writing and is signed by the party asserted to have granted such waiver.

          j. Costs and Expenses. Each party hereto shall bear its own costs, including counsel fees and accounting fees, incurred in connection with the negotiation, preparation of and the Closing under this Agreement, and all matters incident thereto.

          k. Titles Not to Affect Interpretation. The titles of paragraphs and subparagraphs contained in this Agreement are for convenience of reference only, and they neither form a part of this Agreement nor are they to be used in the construction or interpretation hereof.

          l. Execution in Counterparts; Facsimile Signatures. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original as against any party whose signature appears thereon, and all of which shall together constitute one and the same instrument. This Agreement shall become effective when one or more such counterparts have been signed by each of the parties and delivered to the other party. A facsimile signature will have the same force and effect as an original signature.

          m. Gender. Words used herein, regardless of the gender specifically used, shall be deemed and construed to include any other gender, masculine, feminine, or neuter, as the context requires.

          n. Number of Days. In computing the number of days for purposes of this Agreement, all days shall be counted, including Saturdays, Sundays, and holidays celebrated in the United States; provided, however, that if the final day of any period falls on a Saturday, Sunday, or holiday celebrated in the United States, then the final day shall be deemed to be the next day which is not a Saturday, Sunday, or holiday celebrated in the United States.

          o. Transfer Taxes. Any sales, use or other transfer taxes arising out of or incurred in connection with the transactions contemplated by this Agreement shall be paid by Seller; provided that Buyer shall deliver to Seller any resale certificate for inventory or clearance certificate, receipts or similar documents that may be required.

     IN WITNESS WHEREOF, the parties have executed this Amended and Restated Agreement on this 24^th day of January 2008.
