RECITALS

WHEREAS, Sellers own all of the issued and outstanding common stock, $1.00 par value per share, of ColonialWebb Contractors Company, a Virginia corporation (“Colonial” or the “Company”), such stock constituting all of the issued and outstanding capital stock (of all classes) of the Company (the “Stock”);

WHEREAS, Purchaser desires to purchase from Sellers, and Sellers desire to sell to Purchaser, all of the Stock upon the terms and conditions set forth herein;

WHEREAS, Sellers are making certain representations, warranties, and indemnities herein as an additional inducement to enter into this Agreement;

WHEREAS, as an inducement to Purchaser entering into this Agreement, Howard W. Webb and Howard M. Webb have joined this Agreement for purposes of making the covenants set forth in Articles IV and V;

WHEREAS, the Parties have agreed to the sale and purchase of the Stock pursuant to the terms of this Agreement; and

WHEREAS, capitalized terms used herein but not otherwise defined herein shall have the meanings ascribed to them in Exhibit A attached hereto.

NOW, THEREFORE, in consideration of the premises and the respective representations, warranties and covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

ARTICLE I
PURCHASE AND SALE; CLOSING

SECTION 1.1               Purchase and Sale of Stock.  Subject to the terms and conditions of this Agreement, Sellers hereby sell, convey, transfer, and deliver to Purchaser, and Purchaser hereby purchases, all of the Stock, free and clear of all Encumbrances.

SECTION 1.2               Purchase Price.  The aggregate consideration for the Stock and the covenants made in Articles IV and V hereof (the “Purchase Price”) shall equal Eighty-One

Million Two Hundred Seventy-Two Thousand Four Hundred Ninety Dollars and No Cents ($81,272,490.00) plus the Working Capital Adjustment, plus an Earn-Out (as defined below).  The Purchase Price shall be subject to certain post-closing adjustments as provided in this Agreement.  The Purchase Price shall be paid by Purchaser to Sellers by (i) a one-time cash payment in immediately available funds of Fifty-Seven Million Seventy-Two Thousand Four Hundred Ninety Dollars and No Cents ($57,072,490.00) plus the Estimated Working Capital Adjustment payable at Closing to Sellers, which cash payment shall be allocated to Sellers in accordance with the percentage interests set forth on Schedule 1.2(a), and (ii) the execution and delivery to Sellers of promissory notes in the aggregate amount of Twenty Four Million Two Hundred Thousand Dollars and No Cents ($24,200,000.00) in the form attached hereto as Exhibit B (each, a “Note”).  Further, at the times and on the terms set forth in the Earn-Out Agreement attached as Exhibit C (the “Earn-Out Agreement”), Purchaser shall pay to Sellers the Earn-Out, if any (as that term is defined in the Earn-Out Agreement).

SECTION 1.3               Working Capital Purchase Price Adjustment.

(a)           Prior to the Closing Date, Sellers shall deliver to Purchaser a statement setting forth in reasonable detail Sellers’ estimate of the Working Capital Adjustment (the “Estimated Working Capital Adjustment”), which calculation shall be acceptable to Purchaser, acting reasonably.

(b)           As promptly as practicable after the Closing Date, but in no event later than sixty (60) days following the Closing Date, Purchaser shall cause to be prepared and delivered to Sellers (i) a balance sheet as of the Closing Date (the “Closing Date Balance Sheet”), (ii) a calculation of gross revenues for the twelve-month period ending on the Closing Date (the “Gross Revenue Amount”) and (iii) a statement setting forth Purchaser’s calculation of  the Working Capital as of the Closing Date (the “Closing Working Capital”), including supporting schedules for each line item comprising Closing Working Capital (the “Purchaser’s Closing Working Capital Statement” and, collectively with the items delivered pursuant to clauses (i) and (ii) of this sentence, the “Purchaser’s Adjustment Documents”).  In the event Sellers do not object to the Purchaser’s Adjustment Documents by written notice of objection delivered to Purchaser within thirty (30) days after Sellers’ receipt of the Purchaser’s Adjustment Documents, the Purchaser’s Adjustment Documents shall be deemed final and binding on the Parties.  A notice of objection under this Section 1.3(b) shall specify in reasonable detail all disputed items contained in the Purchaser’s Adjustment Documents.  During the thirty (30) day period following Purchaser’s receipt of such notice of objection (as the same may be extended by mutual agreement of the Parties, the “Resolution Period”), the Parties shall attempt to resolve their differences and any resolution by them as to any disputed items shall be final and binding.  Any items remaining in dispute at the end of the Resolution Period shall be submitted to arbitration in accordance with Section 1.3(d).

(c)           During the twenty-one (21) days following the Closing Date, the Parties shall attempt to agree upon a reasonable accrual for the Company’s self-insured liabilities as of the Closing Date (the “Self-Insurance Accrual”).  If the Parties have not agreed upon the Self-Insurance Accrual by the end of such period, the Parties shall select an independent actuary (the “Actuary”) to calculate the amount of the Self-Insurance Accrual.  If the Parties cannot agree on the selection of the Actuary, each Party shall have the right to request the American Arbitration

2

Association to appoint the Actuary.  The Actuary shall be a certified actuary who has not had a material relationship with Purchaser, the Company, Sellers or any of their respective Affiliates within the past two years.  Purchaser and Sellers shall use their commercially reasonable efforts to cause the Actuary to render its calculation of the Self-Insurance Accrual within twenty-one (21) days of the selection of the Actuary.  The determination by the Actuary of the Self-Insurance Accrual shall be provided to the arbitrator in any arbitration pursuant to Section 1.3(d), but shall not be binding on the Parties and any continuing dispute among the Parties as to the amount of the Self-Insurance Accrual shall be resolved, along with any other items in dispute at the end of the Resolution Period, by arbitration conducted pursuant to Section 1.3(d).  Notwithstanding anything in this Agreement to the contrary, in the event that the Self-Insurance Accrual, as agreed to by the Parties or as determined pursuant to arbitration, is different than the amount of such accrual on the Balance Sheet Date, only fifty percent (50%) of such excess or shortfall shall increase Current Liabilities or decrease Current Assets, as the case may be, in the calculation of Closing Working Capital.  The fees and expenses of the Actuary shall be borne fifty percent (50%) by Purchaser and fifty percent (50%) by Sellers.

(d)           If within ten (10) days following the end of the Resolution Period, the Parties have been unable to agree on the selection of an independent certified public accounting firm to serve as the arbitrator, each Party shall have the right to request the American Arbitration Association to appoint the arbitrator.  The arbitrator shall be an independent certified public accounting firm that has not had a material relationship with Purchaser, the Company, Sellers or any of their respective Affiliates within the past two years.  Purchaser and Sellers shall use their commercially reasonable efforts to cause the arbitrator to render a decision in accordance with this Section 1.3(d) along with a statement of reasons therefor within thirty (30) days of the submission of the dispute to the arbitrator, or a reasonable time thereafter.  Each Party shall submit to the arbitrator within the first five (5) days after the initiation of the arbitration its last best offer on the item(s) in dispute including reasonably detailed documentation showing such Party’s calculations of Closing Working Capital, the Gross Revenue Amount and each line item of the Closing Date Balance Sheet that is relevant to any calculation required pursuant to Sections 1.3, 4.9 and 5.2 of this Agreement, including without limitation, each reserve against any liability as of the Closing Date (collectively, the “Closing Financial Calculations”).  Upon receipt of the last best offer of both Parties, the arbitrator shall provide the Parties with each other’s last best offer.  The last best offers submitted by the Parties must incorporate any items agreed upon or deemed to be agreed upon pursuant to clause (b) or (c) of this Section 1.3.  As to each matter in dispute, the arbitrator shall determine which of the Parties’ last best offers is more accurate and shall select that offer as the final determination of the matter in dispute.  For the avoidance of doubt, (i) the arbitrator may not compromise and make a determination different from the last best offers submitted by the Parties, and (ii) a Party’s last best offer with respect to all items in dispute in the Closing Financial Calculations shall be deemed to be a single offer to be accepted or rejected in whole by the arbitrator.  The decision of the arbitrator shall be final and binding on the Parties and shall constitute an arbitral award that is final, binding and non-appealable and upon which a judgment may be entered by a court having jurisdiction thereover.  The fees and expenses of the arbitrator shall be paid by Purchaser if Sellers’ last best offer is selected by the arbitrator or by the Sellers if Purchaser’s last best offer is selected by the arbitrator.

3

(e)           Upon the determination in accordance with this Section 1.3 of Closing Working Capital and the Gross Revenue Amount, the Working Capital Adjustment shall be recalculated.  If the final Working Capital Adjustment is greater than the Estimated Working Capital Adjustment, Purchaser shall pay such difference to Sellers.  If the final Working Capital Adjustment is less than the Estimated Working Capital Adjustment, Sellers shall pay such difference to Purchaser.  Such payment shall be made by wire transfer in immediately available funds to an account specified in writing by the Party to whom the payment is owed within five (5) business days after the final and binding determination of each of Closing Working Capital and the Gross Revenue Amount.  Any amount owed but not paid within such five (5) business day period shall bear interest at an annual rate of six percent (6%) from the end of such period until paid.

(f)            From the Closing Date and until the final determination of the purchase price adjustment pursuant to Section 1.3(e), Sellers and their representatives shall have reasonable access during normal business hours to all relevant books and records (including the working papers, if any, of Purchaser’s and the Company’s auditors) and personnel of the Company in order to allow Sellers and their representatives to review and evaluate the accuracy of Purchaser’s Adjustment Documents.

SECTION 1.4               Accrual Adjustment to Purchase Price.

(a)           As promptly as practical after the twenty-four (24) month anniversary of the Closing Date (the “Adjustment Date”) but in no event later than sixty (60) days after the Adjustment Date, the Parties shall perform an analysis (the “Accrual Analysis”) of the accruals with respect to each Material Contract providing for design, engineering, manufacturing, distribution, sale, lease, installation, repair, service, maintenance or construction work that has not been fully performed as of Closing (collectively, the “WIP Projects”).  The Accrual Analysis shall show the amount (the “Accrual Adjustment”) by which the Company’s net earnings as of the Closing were overstated or understated by reason of any disproportionate accruals of revenues and expenses on the WIP Projects as of the Closing.  The Accrual Adjustment shall be calculated on a contract-by-contract basis using the following formula:

For example, if at Closing the Company has earned $600,000 of revenues and accrued $500,000 of expenses with respect to a particular project and upon completion of the project, total revenues earned are $1,000,000 and total costs are $800,000, the Accrual Adjustment with respect to that project would be positive $25,000.  The Accrual Analysis as of the Adjustment Date shall cover WIP Projects completed on or before such date.  The Accrual Adjustment shall be determined on an aggregate basis netting out over and under accruals.  Any items remaining in dispute at the end of any such sixty (60) day period shall be submitted to arbitration in accordance with Section 1.4(b).

(b)           If within ten (10) days following the end of the sixty (60) day period referenced in Section 1.4(a), the Parties have been unable to agree on the selection of an independent certified public accounting firm to serve as the arbitrator, each Party shall have the right to request the American Arbitration Association to appoint the arbitrator, except that if an

4

arbitrator has previously been selected or appointed pursuant to Section 1.3(d), such arbitrator shall serve as the arbitrator under this Section 1.4(b).  The arbitrator shall be an independent certified public accounting firm that has not had a material relationship with Purchaser, the Company, the Sellers or any of their respective Affiliates within the past two (2) years.  Purchaser and Sellers shall use their commercially reasonable efforts to cause the arbitrator to render a decision in accordance with this Section 1.4(b) along with a statement of reasons therefor within thirty (30) days of the submission of the dispute to the arbitrator, or a reasonable time thereafter.  Each Party shall submit to the arbitrator within the first five (5) days after the initiation of the arbitration its last best offer on the item(s) in dispute including reasonably detailed documentation showing such Party’s calculation of the Accrual Adjustment.  Upon receipt of the last best offer of both Parties, the arbitrator shall provide the Parties with each other’s last best offer.  The arbitrator shall determine which of the Parties’ last best offers is more accurate and shall select that offer as the final determination of the matters in dispute.  For the avoidance of doubt, (i) the arbitrator may not compromise and make a determination different from the last best offers submitted by both Parties, and (ii) the arbitrator may select the last best offer of a Party different than the Party whose last best offer was selected in any arbitration under Section 1.3(d).  The decision of the arbitrator shall be final and binding on the Parties and shall constitute an arbitral award that is final, binding and non-appealable and upon which a judgment may be entered by a court having jurisdiction thereover.  The fees and expenses of the arbitrator shall be paid by Purchaser if Sellers’ last best offer is selected by the arbitrator or by the Sellers if Purchaser’s last best offer is selected by the arbitrator.

(c)           Upon the determination in accordance with this Section 1.4 of the Accrual Adjustment, the Purchase Price shall be recalculated.  If the Accrual Adjustment is negative, Sellers shall pay the absolute value thereof, if any, in excess of $250,000 to Purchaser.  If the Accrual Adjustment is positive, Purchaser shall pay the portion thereof, if any, in excess of $250,000 to Sellers; provided that Purchaser shall not be required to make any payment to Sellers to the extent that, giving effect to that payment as an expense, the Company would thereby incur or extend an aggregate net loss on the WIP for the period from the Closing to the Adjustment Date.  Such payment shall be made by wire transfer in immediately available funds to an account specified in writing by the Party to whom the payment is owed within five (5) business days after the final and binding determination of the Accrual Adjustment.  Any amount owed but not paid within such five (5) business day period shall bear interest at an annual rate of six percent (6%) from the end of such period until paid.

(d)           From the Closing Date and until the final determination of the purchase price adjustment pursuant to Section 1.4(c), Sellers and their representatives shall have reasonable access during normal business hours to all relevant books and records (including the working papers, if any, of Purchaser’s and the Company’s auditors) and personnel of the Company in order to allow Sellers and their representatives to perform the Accrual Analysis.

SECTION 1.5               Closing Date.  The closing of the transactions contemplated by this Agreement (the “Closing”) shall take place effective at 12:01 a.m. EDT on July 28, 2010, in the offices of McGuireWoods LLP, Richmond, Virginia, who shall hold all documents in trust until a fully executed original is delivered to all Parties to this Agreement (or at such other place as the Parties hereto shall mutually agree).  The date of the Closing is herein referred to as the “Closing Date.”  The Parties contemplate that executed versions of the documents required to be delivered

5

(i)            It is specifically agreed that the respective Noncompete Terms stated at the beginning of this Section 4.1 as they apply to each Seller Individual, during which the agreements and covenants of the Seller Individuals made in this Section 4.1 shall be effective, shall be computed by excluding from such computation any time during which such Seller Individual is in violation of any provision of this Section 4.1.

SECTION 4.2             Confidential Information.  Except in response to legal process (where Sellers have, to the extent permitted by law, promptly notified the Company so that it may seek appropriate relief), Sellers shall not divulge, furnish, or make accessible to anyone or use in any way any confidential or secret knowledge or information of the Company, including, without limitation, trade secrets, confidential or secret designs, processes, formulae, plans, devices, or material (whether or not patented or patentable) directly or indirectly useful in any aspect of the business of the Company, any customer or supplier lists of the Company, any confidential or secret development or research work of the Company or any other confidential information or secret aspects of the business of the Company including with respect to the transactions contemplated by this Agreement and the Agreement itself.  Sellers acknowledge that the above-described knowledge or information constitutes a unique and valuable asset of the Company and represents a substantial investment of time and expense by the Company, and that any disclosure or other use of such knowledge or information other than for the sole benefit of the Company would be wrongful and would cause irreparable harm to the Company and Purchaser.

SECTION 4.3             Guarantees.  On or before the one hundred twentieth (120th) day following the Closing, Purchaser will, with Sellers’ full disclosure and cooperation, cause the Company to obtain a full release of any guarantees of any Sellers set forth on Schedule 4.3, and from and after the Closing the Purchaser agrees to indemnify, defend, and hold the Sellers harmless from and against any claims of any Person made with respect to any of such guarantees to the extent (but only to the extent) such claims relate to the failure of the Company or the Purchaser to perform their obligations after the Closing Date.

SECTION 4.4             Expenses.  Except for the exceptions set forth on Schedule 4.4, each Party to this Agreement will bear its respective expenses incurred in connection with the preparation, execution, and performance of this Agreement and the transactions contemplated herein, including all fees and expenses of its Representatives.  Sellers shall be responsible for all expenses incurred by the Company prior to the Closing in connection with the transactions contemplated herein.

SECTION 4.5             Further Assurances.  From time to time after the Closing, at a Party’s reasonable request but without further consideration, the other Party will execute and deliver such other instruments of conveyance and transfer and take such other action as the other Party may reasonably require to more effectively vest good and marketable title to the Stock in the Purchaser and to carry out the intent of this Agreement.

SECTION 4.6             Further Consents.  If the transfer of the Stock to Purchaser at the Closing without the consent or approval of a third person would constitute a breach of any Contract or other obligation to which the Company is a party or by which the Company or any of its properties are bound or create in any other Person the right to declare a default in respect of, or to cancel or terminate, any such Contract or other obligation or any Governmental

23

Authorization, license, permit, franchise, or other right of the Company, and if such consent or approval (or an effective waiver thereof) is not obtained prior to the Closing, then Purchaser shall have the right by an instrument executed in writing and delivered to Sellers at the Closing to cause the transfer of the Stock not to carry with it an assignment of the item or items that necessitate such consent or approval until such consent or approval (or an effective waiver thereof) shall have been obtained.  In such an event, Sellers will continue after Closing to use their commercially reasonable efforts promptly to obtain such consents and approvals, or effective waivers thereof, and will cooperate with Purchaser in any reasonable arrangement designed to provide Purchaser with the benefit of the Company’s rights thereunder.

SECTION 4.7             Cooperation; Access to Records.  The Parties shall reasonably cooperate with each other and provide each other reasonable access to books, records, and personnel for the purpose of preparing Tax Returns and defending any Tax claim or audit.

SECTION 4.8             Employees.  Sellers, the Company, and their respective Affiliates have not and will not take any actions inconsistent with maintaining the availability of the services of the Company’s employees following the Closing.

SECTION 4.9             Accounts Receivable.  Purchaser hereby covenants and agrees to use its reasonable best efforts to cause the Company (i) to collect all outstanding accounts receivable, notes receivable and employee receivables of the Company as of the Closing Date (the “Accounts Receivable”) during the 24-month period following the Closing Date and (ii) to bill and collect all retainage of the Company as of the Closing Date during the 36-month period following the Closing Date.  In the event that during the 36-month period following the Closing Date, Purchaser or the Company receives payment with respect to any receivable that was written off in full as of the Closing Date and such payment exceeds $35,000, Purchaser shall, within fifteen (15) days thereafter, pay the amount thereof to Sellers in accordance with their respective percentage interests set forth on Schedule 1.2(a).  Any amount owed but not paid within such fifteen (15) business day period shall bear interest at an annual rate of six percent (6%) from the end of such period until paid.

SECTION 4.10           Covenants by Webbs.  Howard W. Webb and Howard M. Webb each join in the covenants set forth in Sections 4.2 through 4.9 and shall have the same rights and obligations thereunder as if they were Sellers.

ARTICLE V
INDEMNIFICATION

SECTION 5.1             Waiver of Right to Indemnification.  The waiver of any condition based on the accuracy of any representation or warranty (as may be modified by any Disclosure Schedule), or on the performance of or compliance with any covenant or obligation, will not affect the right to indemnification in accordance with the provisions of this Article V, unless such waiver shall expressly state that it includes a waiver of rights to indemnification under this Article V.

SECTION 5.2             Indemnification and Payment of Damages by Sellers.  From and after the Closing, Sellers will indemnify, defend, and hold harmless Purchaser, the Company, and

24

their respective Representatives and Affiliates (collectively, the “Purchaser Indemnified Persons”) from, against, and in respect of any and all Damages sustained or incurred by any Purchaser Indemnified Person to the extent relating to, resulting from, or arising out of:

(a)           any breach of or inaccuracy in any representation or warranty made by Sellers in Article II of this Agreement and its accompanying schedules:

(b)           any breach or nonfulfillment by any Seller or Seller Individual of any covenant or obligation of any Seller in this Agreement or any certificate delivered hereunder;

(c)           any claim by Harris Williams & Co., or without limitation, any other Person for brokerage or finder’s fees or commissions or similar payments based upon any agreement or understanding alleged to have been made by any such Person with any Seller or the Company (or any of their respective Representatives) in connection with any of the transactions contemplated in this Agreement;

(d)           any payments, claims or Proceedings resulting from, arising out of, relating to, or caused by any Liability of the Company for any Taxes of the Company with respect to any Tax year or portion thereof ending on or before the Closing Date (or for any Tax year beginning before and ending after the Closing Date to the extent allocable (determined in a manner consistent with Section 6.2 hereof) to the portion of such period beginning before and ending on the Closing Date) and to the extent such Taxes are not reflected in the reserve for Tax Liability on the Company’s books and records;

(e)           any claims or Proceedings resulting from, arising out of, relating to or caused by any Liability of any Seller related to Sellers’ relationship/arrangements under the Special Equity Incentive Plan;

(f)            net of reserves reflected in the Closing Balance Sheet, the collectability within the 36-month period following the Closing Date of the unbilled retainage of the Company as of the Closing Date; provided that this indemnity shall not apply to retainage, or any portion thereof, to the extent it is the subject of dispute (other than arising out of an ability to pay) between the Company and the customer and provided, further, that any such retainage that is reimbursed by Sellers to Purchaser under this Section 5.2(f) shall, at the request of Sellers, be assigned by Purchaser to Sellers; or

(g)           net of reserves for bad debts and write-offs reflected in the Closing Date Balance Sheet, the collectability within the 24-month period following the Closing Date of the Accounts Receivable as of the Closing Date; provided that any such receivables that are reimbursed by Sellers to Purchaser under this Section 5.2(g) shall, at the request of Sellers, be assigned to Sellers.

To the extent that Sellers become obligated to make any monetary payment to Purchaser, Purchaser retains a reasonable right of offset in the principal of the Note.  The right of offset is limited to a reasonable estimate of damages and will be applied to payments otherwise due under the Note in the inverse order of maturity, such that later due payments will be offset first. Interest will continue to accrue on any offset from the Note that later proves to be unneeded.

25

With respect to indemnification matters not involving Proceedings brought or asserted by third parties, within ten (10) days after receipt of written notification from the Purchaser Indemnified Persons supported by reasonable documentation setting forth the nature of the circumstances entitling the Purchaser Indemnified Persons to indemnity hereunder, Sellers, at no cost or expense to the Purchaser Indemnified Persons, shall diligently commence resolution of such matters in a manner reasonably acceptable to the Purchaser Indemnified Persons and shall diligently and timely prosecute such resolution to completion.  If Sellers, within ten (10) days after their receipt of such notice (or such shorter time as may be necessary under the circumstances), fail to diligently commence resolution of such matters in a manner reasonably acceptable to the Purchaser Indemnified Persons, the Purchaser Indemnified Persons shall have the right to undertake all appropriate and reasonable actions to resolve or otherwise address such matters at the sole expense of Sellers.  If Sellers dispute any Liability in connection with such claim, Sellers shall pay any undisputed part of such Liability and Purchaser and Sellers shall have thirty (30) days to resolve any remaining dispute.  If litigation or any other Proceeding is commenced between Sellers and any Purchaser Indemnified Person, the prevailing party in such litigation or other Proceeding shall be entitled to recover all reasonable costs and expenses incurred in connection with such litigation or other Proceeding, including, without limitation, attorneys’ fees.  If litigation or any other Proceeding is commenced or threatened by any third party for which the Purchaser Indemnified Persons are entitled to indemnification under this Section 5.2, the provisions of Section 5.4 shall control.  Any payments owed by Sellers to the Purchaser Indemnified Persons under this Section 5.2 may, at Sellers’ election, be satisfied by a reduction in the principal amount of the Note, with such reduction being applied to principal payments otherwise due under the Note in the inverse order of maturity, such that later due payments will be offset first.

SECTION 5.3             Indemnification by Purchaser.  From and after the Closing, Purchaser will indemnify, defend, and hold harmless each Seller and his Representatives and Affiliates (collectively, the “Seller Indemnified Persons”) from, against and in respect of any and all Damages sustained or incurred by any Seller Indemnified Person to the extent relating to, resulting from or arising out of:

(a)           any breach of or inaccuracy in any representation or warranty made by Purchaser in Article III of this Agreement;

(b)           any breach or nonfulfillment by Purchaser of any covenant or obligation of Purchaser (or the Company after Closing, as applicable) in this Agreement; or

(c)           any claim by any Person for brokerage or finder’s fees or commissions or similar payments based upon any agreement or understanding alleged to have been made by such Person with Purchaser (or any of its Representatives) in connection with any of the transactions contemplated herein; or

With respect to matters not involving Proceedings brought or asserted by third parties, within ten (10) days after receipt of written notification from the Seller Indemnified Persons supported by reasonable documentation setting forth the nature of the circumstances entitling the Seller Indemnified Persons to indemnity hereunder, Purchaser, at no cost or expense to the Seller Indemnified Persons, shall diligently commence resolution of such matters in a manner

26

reasonably acceptable to the Seller Indemnified Persons and shall diligently and timely prosecute such resolution to completion.  If Purchaser, within ten (10) days after its receipt of such notice (or such shorter time as may be necessary under the circumstances), fails to diligently commence resolution of such matters in a manner reasonably acceptable to the Seller Indemnified Persons, the Seller Indemnified Persons shall have the right to undertake all appropriate and reasonable actions to resolve or otherwise address such matters at the sole expense of Purchaser to the extent such matters are subject to indemnification under this Section 5.3.  If Purchaser disputes its Liability in connection with such claim, it shall pay any undisputed part of such Liability and Sellers and Purchaser shall have thirty (30) days to resolve any remaining dispute.  If litigation or any other Proceeding is commenced between Purchaser and any Seller Indemnified Person, the prevailing party in such litigation or other Proceeding shall be entitled to recover all reasonable costs and expenses incurred in connection with such litigation or other Proceeding, including, without limitation, attorneys’ fees.  If litigation or any other Proceeding is commenced or threatened by any third party for which the Seller Indemnified Persons are entitled to indemnification under this Section 5.3, the provisions of Section 5.4 shall control.

SECTION 5.4             Notice and Defense of Third Party Claims.  If any Proceeding (including any Proceeding relating to Taxes) shall be brought or asserted under this Article against an indemnified party or any successor thereto (the “Indemnified Person”) in respect of which indemnity may be sought under this Article from an indemnifying person or any successor thereto (the “Indemnifying Person”), the Indemnified Person shall give prompt written notice of such Proceeding to the Indemnifying Person; provided that failure of an Indemnified Person to give prompt written notice of any claim shall not release, waive or otherwise affect the Indemnifying Person’s obligations with respect thereto except to the extent that the Indemnifying Person is adversely affected in its ability to defend against such claim or is otherwise prejudiced thereby.  The Indemnifying Person shall have the right to assume the defense and reasonable control thereof, including the employment of counsel reasonably satisfactory to the Indemnified Person and the payment of all expenses so long as the Indemnifying Person gives written notice to the Indemnified Person within fifteen (15) days after the Indemnified Person has given the Indemnifying Person notice of the Proceeding that the Indemnifying Person will indemnify the Indemnified Person from and against the entirety of any and all Damages that the Indemnified Person may suffer resulting from, arising out of, relating to or caused by the Proceeding.  In no event shall any Indemnified Person be required to make any expenditure or bring any cause of action to enforce the Indemnifying Person’s obligations and Liability under and pursuant to the indemnifications set forth in this Article.  The Indemnified Person shall have the right to employ separate counsel in any of the foregoing Proceedings and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the Indemnified Person unless the Indemnified Person has been advised in writing by counsel that there exist actual or potential conflicts of interest that make representation of the Indemnifying Person and the Indemnified Person by the same counsel inappropriate.  The Indemnified Person’s right to participate in the defense or response to any Proceeding should not be deemed to limit or otherwise modify its obligations under this Article.  In the event that the Indemnifying Person, within five (5) days after notice of any such Proceeding, fails to assume the defense thereof, the Indemnified Person shall have the right to undertake the defense, compromise or settlement of such Proceeding for the account and at the expense of the Indemnifying Person, subject to the right of the Indemnifying Person to assume the defense and reasonable control of such Proceeding with counsel reasonably satisfactory to the Indemnified Person at any time prior to the settlement,

27

compromise or final determination thereof. If the Indemnifying Person assumes the defense of a Proceeding, the Indemnifying Person shall not, without the Indemnified Person’s prior written consent, settle or compromise any Proceeding or consent to the entry of any judgment with respect to any Proceeding unless such settlement, compromise or judgment; (i) requires solely the payment of money damages by the Indemnifying Person and such damages are paid by the Indemnifying Person, (ii) includes as an unconditional term thereof the release by the claimant or the plaintiff of the Indemnified Person from all liability in respect of such Proceeding, (iii) involves no finding or admission of any liability of the Indemnified Person or violation of any Legal Requirement or the rights of any Person, and (iv) does not provide for any injunction or place any restriction on the operation of the Business or any Indemnified Person.  The Indemnified Person shall not be entitled to recovery from the Indemnifying Person with respect to any compromise or settlement of any Proceeding effected by the Indemnified Person without the consent (which may not be unreasonably withheld) of the Indemnifying Person; provided that failure of the Indemnifying Person to respond to a request for consent within twenty (20) days following receipt of written notice thereof shall be deemed to constitute consent.

SECTION 5.5             Payment; Interest.  The Indemnifying Party shall make any payment required to be made under this Article in cash promptly after the date (the “Payment Due Date”) that is the later of (i) the date such payment obligation becomes undisputed or resolved by a non-appealable judicial determination, and (ii) the date the Indemnifying Person receives written demand therefor from the Indemnified Person accompanied by reasonable documentation.  Any amounts required to be paid by an Indemnifying Party under this Article that are not paid within thirty (30) business days of the Payment Due Date shall thereafter be deemed delinquent, and the Indemnifying Party shall pay to the Indemnified Party immediately upon demand, interest at the rate of six percent (6%) per annum, not to exceed the maximum non-usurious rate allowed by applicable law, from the date such payment becomes delinquent to the date of payment of such delinquent sums.

SECTION 5.6             Limitations.  Notwithstanding anything to the contrary contained in this Agreement or in any certificate, schedule, statement, document or instrument furnished hereunder, Sellers’ and Purchaser’s obligations of indemnification are limited as set forth in this Section 5.6.

(a)           Basket.  The Parties shall not be entitled to indemnification pursuant to this Agreement unless and until the aggregate of all Damages with respect to any such indemnification matters exceeds the amount set forth on Schedule 5.6 (the “Basket Amount”), in which event the Party or person seeking indemnity may recover all Damages incurred in excess of the Basket Amount from the first dollar above the Basket Amount.  With respect to Sellers, the Basket Amount shall be allocated among them in accordance with their respective percentage interests as set forth on Schedule 1.2(a).

(b)           Cap.  Sellers’ liability for Damages pursuant to this Article V shall not exceed, in the aggregate, the amount set forth on Schedule 5.6, which cap shall be allocated among Sellers in accordance with their respective percentage interests as set forth on Schedule 1.2(a).

28

(c)           Per-Claim Threshold.  No representation or warranty made in Article II or III shall be deemed to be breached and no claim for indemnification therefore may be made unless the Damages resulting from or arising out of any individual circumstance or occurrence exceed the amount set forth on Schedule 5.6 (the “Per Claim Threshold”).  If such Damages exceed the Per Claim Threshold, the full amount thereof (after taking into account the limitations set forth in Sections 5.6(e), (f), (g) and (h)) shall be taken into account in determining whether, and the extent to which, the Basket Amount has been met and, if the Basket Amount has been met, shall be subject to indemnification under this Article except to the extent limited by this Section 5.6.

(d)           Survival.  The representations and warranties of the Parties contained in this Agreement shall survive the Closing Date for twenty-one (21) months; provided, however, that the representations and warranties contained in Sections 2.1, 2.2, 2.3, 2.11, 2.23, 2.25 (only with respect to Indebtedness for borrowed money), 3.1, 3.2 and 3.3 shall survive until the expiration of the applicable statute of limitations thereto, at which time they shall expire (as applicable, the “Survival Date”); and provided further that a claim for indemnification pursuant to Section 5.2(a) or Section 5.3(a) shall survive the applicable Survival Date if written notice, given in good faith, of the specific claim (including appropriate details) thereof is given to Sellers or Purchaser, as the case may be, on or before the applicable Survival Date.

(e)           Insurance; Tax Effect.  The amount of Damages that the Purchaser Indemnified Persons shall be entitled to recover under Section 5.2 shall be determined (i) net of any amounts paid by any third-party insurance carrier to the indemnified party with respect to such Damages and (ii) after taking into account any Tax benefit realized by the Purchaser Indemnified Persons with regard to such Damages.

(f)            Change in Accounting or Law.  No Party shall be liable for Damages suffered by an indemnified person to the extent such Damages arose from (i) a change in accounting policy or practice made after the Closing that is required by GAAP or any change in Law or (ii) any legislation not in force on the Closing Date.

(g)           Actions of Indemnified Persons.  No Party shall be liable for Damages suffered by an indemnified person to the extent such Damages result from a failure on the part of any indemnified person or its Affiliates to exercise good faith in not jeopardizing or prejudicing the interests of the indemnifying person or otherwise arises out of any action wrongfully taken or omitted to be taken by an indemnified person or its Affiliates.

(h)           Incidental or Consequential Damages.  Neither Purchaser nor Sellers shall be liable for any incidental or consequential Damages, except if such Damages are awarded in a third-party claim for which such Party has an indemnification obligation.

(i)            Exceptions.  Notwithstanding the foregoing, the limitations set forth in subsections (a), (b) and (c) of this Section 5.6 shall not apply to claims made pursuant to, or as a result of a breach of the payment obligations under, Sections 1.3, 1.4, 4.9, 5.2(c), 5.2(d), 5.2(f) and 5.2(g) of this Agreement.

SECTION 5.7             Exclusive Remedy.  Except with respect to claims of, or causes of

29

action arising from, fraud or criminal misconduct, and subject to a Party’s right to seek injunctive relief, as appropriate, to enforce any covenant made by another Party hereunder, and except for any additional remedies provided to Sellers and Purchaser under the Note and the Earn-Out Agreement following the Closing, the indemnification provided in this Article V shall constitute the exclusive remedy with respect to (i) a breach of the representation, warranties, covenants and agreements contained in this Agreement, (ii) any events, circumstances or conditions that are the subject of the representations, warranties, covenants and agreements contained in this Agreement, (iii) any other events, circumstances or conditions relating to the ownership or operation of the Company or its business prior to the Closing and whether any claims or causes of action asserted with respect to such matters are brought in contract, tort or any other legal theory whatsoever.

SECTION 5.8             Indemnification Obligations of Webbs.  Howard W. Webb guarantees the performance by HWWJR LC of its obligations under this Article V and, in doing so, shall be entitled to all of the rights and defenses that HWWJR LC may have.  Howard M. Webb guarantees the performance by HMWSR LC of its obligations under this Article V and, in doing so, shall be entitled to all of the rights and defenses that HMWSR LC may have.

ARTICLE VI
TAX MATTERS

SECTION 6.1             Tax Periods Ending on or Before the Closing Date.  At the Company’s expense, Sellers shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for the Company for all periods ending on or prior to the Closing Date that are filed after the Closing Date, including but not limited to, any short-period Tax return resulting from the transactions contemplated herein.  Such Tax Returns shall be prepared in a manner consistent with the prior practice of the Company.  Sellers shall provide copies of such Tax Returns to Purchaser and its authorized representatives for review at least thirty (30) days prior to the due date and shall make such revisions to such Tax Returns as are reasonably requested by Purchaser.  To the extent permitted by law, Sellers shall include any income, gain, loss, deduction, or other items for such periods on their Tax Returns in a manner consistent with the Schedule K-1s prepared by (or caused to be prepared by) Sellers for such periods.  Any Tax deduction associated with the Special Equity Incentive Plan prior to Closing will inure to the benefit of Sellers.

SECTION 6.2             Tax Periods Beginning Before and Ending After the Closing Date.  Purchaser shall prepare or cause to be prepared and file or cause to be filed any Tax Returns of the Company for Tax periods that begin before the Closing Date and end after the Closing Date (“Straddle Period”).  Any Tax Return for any Straddle Period shall be prepared in a manner and utilizing judgments consistent with the Company’s prior practice, unless such practices, manner or judgments are unreasonable or improper.  Purchaser shall provide Sellers and their authorized representatives with copies of such Tax Returns at least thirty (30) days prior to the due date and shall make such revisions to such Tax Returns as are reasonably requested by Sellers.  Sellers shall pay to Purchaser within thirty (30) days of the receipt of a request by Purchaser, accompanied by supporting documentation, an amount equal to the excess of (a) the portion of such Taxes that relates to the portion of such Tax period ending on the Closing Date over (b) the Taxes reflected in any reserve for Tax Liability contained in the Company’s books and records.

30

For purposes of this Section 6.2, in the case of any Taxes that are imposed on a periodic basis and are payable for a Straddle Period, the portion of such Tax that relates to the portion of such Straddle Period ending on the Closing Date shall be (i) in the case of any Taxes (including real property Taxes and other property Taxes) other than Taxes based upon or related to income or receipts (or imposed in connection with any sale or other transfer or assignment of property or any other specifically identifiable transaction or event), be deemed to be the amount of such Tax for the entire Straddle Period multiplied by a fraction, the numerator of which is the number of days in the Straddle Period ending on the Closing Date and the denominator of which is the number of days in the entire Straddle Period, and (ii) in the case of any Tax based upon or related to income or receipts (including franchise Taxes) or imposed in connection with any sale or other transfer or assignment of property or any other specifically identifiable transaction or event, the Tax payable by Seller shall be deemed equal to the amount that would be payable if the relevant Straddle Period ended on the Closing Date based on an interim closing of the books as of the end of the Closing Date.  All determinations necessary to give effect to the foregoing allocations shall be made in a manner consistent with prior practice of the Company.

SECTION 6.3             Cooperation on Tax Matters.

(a)           Purchaser, the Company, and Sellers shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns pursuant to this Article VI and any audit, litigation or other Proceeding with respect to Taxes.  Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information that are reasonably relevant to any such audit, litigation or other Proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder.  The Company and Purchaser shall (i) retain all books and records with respect to Tax matters pertinent to the Company relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by Purchaser or Sellers, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (ii) give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, the Company or Purchaser, as the case may be, shall allow the Sellers to take possession of such books and records.

(b)           Purchaser and Sellers further agree, upon request, to use their reasonable efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereby).

(c)           Purchaser and Sellers further agree, upon request, to provide the other party with all information that either party may be required to report pursuant to Section 6043A of the Code and the Treasury Regulations promulgated thereunder.

SECTION 6.4             Transfer Taxes.  All transfer, documentary, filing, recordation and other similar Taxes (including all real estate transfer Taxes and conveyance and recording fees, if any), that may be imposed upon, or payable or collectible or incurred in connection with, this Agreement and the transactions contemplated hereby shall be borne fifty percent (50%) by

31

Purchaser and fifty percent (50%) by Sellers, and the Party required by applicable law shall file all necessary Tax Returns and other documentation with respect to all such transfer, documentary, filing, recordation, and other similar Taxes, and, if required by applicable law, the other Parties shall, and shall cause their Affiliates to, join in the execution of any such Tax Returns and other documentation.  The expense of such filings shall be paid fifty percent (50%) by Purchaser and fifty percent (50%) by Sellers.

SECTION 6.5             No Code Section 338 Election. Neither Purchaser nor the Company shall make any election under Code §338 with respect to the transactions contemplated by this Agreement.

SECTION 6.6             Refunds and Tax Benefits.  To the extent not reflected in the Closing Date Balance Sheet, any Tax refunds that are received by Purchaser or the Company, and any amounts credited against Tax to which Purchaser or the Company become entitled, that relate to Tax periods or portions thereof ending on or before the Closing Date, allocated in a manner consistent with Section 5.2(d), shall be for the account of Sellers, and Purchaser shall pay over to Sellers any such Tax refund or the amount of any such credit within five (5) business days after receipt or entitlement thereto.  In addition, to the extent that a claim for Tax refund or a proceeding results in a payment or credit against Tax by a taxing authority to Purchaser or the Company of any amount accrued on the Closing Balance Sheet, Purchaser shall pay such amount to Sellers within five business days after receipt or entitlement thereto.  Notwithstanding the foregoing, Purchaser shall receive the tax benefit relating to tax deductible goodwill on the books as of Closing.

SECTION 6.7             Tax Treatment of Transactions. The Parties acknowledge and agree that the purchase and sale of the Stock as contemplated by this Agreement will be treated as a “stock purchase” transaction for federal and state income tax purposes and no election will be made by the Parties pursuant to Code §338(h)(10) or §338(g).  The acquisition of the Stock by Purchaser will terminate the Company’s S election pursuant to Code §1361(b)(1)(B) and §1362(d)(2) and result in an “S Termination Year” for the Company (as defined in Code §1362(e)(4)).  The S Termination Year will be divided into two short tax years — the “S Short Year” (as defined in Code §1362(e)(1)(A)) that ends on the day immediately before the Closing Date, and the C Short Year (as defined in Code §1362(e)(1)(B)) that begins on the Closing Date.  Because more than 50% of the Stock is being transferred to Purchaser in the S Termination Year, the Company will utilize the “closing of the books” method to calculate and report its Taxes for the S Short Year and the C Short Year as required by Code §1362(e)(6)(D).  Howard W. Webb has transferred  17,840.14926 of his Shares to Mitchell Frederick Haddon, Gary Jon Warness, and Curtis Michael Wood (collectively, the “Company Executives”) before the Closing Date in satisfaction of the Company’s obligation under the Special Equity Incentive Plan to make payment to the Company Executives.  Because this transfer has occurred prior to the last day of the S Short Year, any deduction that inures to the Company pursuant to Code §83 and Treasury Regulations §1.83-6(d)(1) or other applicable provision of the Code will inure to the Company during its S Short Year and be passed through to its S shareholders.  Purchaser agrees that this deduction will be reflected on the Company’s tax return for its S Short Year and passed through to its S shareholders as of the last day of the S Short Year.  The employees’ portion of the Company’s required tax withholding obligation that results from the transfer of Stock by Howard W. Webb to the Company Executives as described above has been satisfied by each Company Executive

32

executing and delivering to the Company a promissory note in the amount of his required tax withholding, such promissory note to being due and payable in full at the time of the sale of his Stock to Purchaser.  The promissory notes will be paid by Purchaser paying to the Company Executives a “net” amount of the Purchase Price allocable to their Stock (reduced by the amount of their promissory notes) and by Purchaser depositing with the Company the amounts required to satisfy the promissory notes.  Purchaser agrees that Howard W. Webb and Howard M. Webb will have no liability for such tax withholdings.  In addition, as permitted by Rev. Proc. 2004-53, Sellers will prepare the IRS W-2 Forms for the Company Executives reflecting that the Company has paid this compensation to the Company Executives while it was an S corporation and the S corporation shareholders will receive 100% of the deduction for such compensation.  Because the Company Executives have become shareholders of the Company before the Closing Date, pursuant to Treasury Regulations §1.1377-1(a) the appropriate pro rata shares of the deduction resulting from the Special Equity Incentive Plan award will be allocated by the Company among Howard W. Webb, Howard M. Webb and the Company Executives.  The Company will make appropriate tax withholdings for tax purposes as required by applicable law, and such withholdings will be properly taken into account for purposes of the Working Capital Adjustment pursuant to Section 1.3.  Purchaser agrees to take no action that is inconsistent with the foregoing tax treatment of these transactions.

SECTION 6.8             Other Tax Matters. Without the prior written consent of the other Party, no Party or its Affiliates shall make or change any election, change an annual accounting period, adopt or change any accounting method, file any amended Tax Return, enter into any closing agreement, settle any Tax claim or assessment relating to the Company, surrender any right to claim a refund of Taxes, consent to any extension or waiver of the limitation period applicable to any Tax claim or assessment relating to the Company, or take any other similar action relating to the filing of any Tax Return or the payment of any Tax, if such election, adoption, change, amendment, agreement, settlement, surrender, consent, or other action would have the effect of increasing the Tax liability of the Company for any prior or subsequent Tax periods or portions thereof whether before or after the Closing Date.  Notwithstanding the foregoing, the Parties agree that the Company, as permitted by Revenue Procedure 2008-52, Section 6, will change to a permissible accounting method for the purpose of taking on its final S tax return the amortization deduction for good will of the Company that should have been taken in prior tax years of the Company.
