Capital as of Effective Date is more than the Net Working Capital Requirement,
then the Purchase Price will be adjusted on a dollar for dollar basis and such

equity and the Stockholder's Equity Requirement within ten (10) days following
receipt of the Audit.

                  (d) Any payments to be made to the Sellers under Section
2.5(b) shall be made in accordance with their pro rata ownership of the Company

accurate list for the Company of its name, its jurisdiction of incorporation and

authority to conduct its business as it is now being conducted, to own or use
the properties and assets that it purports to own or use, and to perform all its
obligations under Applicable Contracts. The Company is duly qualified to do

requires such qualification.

         Agreements, the Sellers' Releases, and the Sellers Non-Competition
         Agreements, as applicable (collectively, the "Sellers' Closing
         Documents"), the Sellers' Closing Documents will constitute the legal,
         valid, and binding obligations of Sellers, enforceable against Sellers
         in accordance with their respective terms. Sellers have the absolute
         right, power, authority, and capacity to execute and deliver this
         Agreement and the Sellers' Closing Documents and to perform their
         obligations under this Agreement and the Sellers' Closing Documents.

                  (b) Except as set forth in Part 3.2 of the Disclosure Letter,
         neither the execution and delivery of this Agreement by the Sellers nor
         the consummation or performance of any of the Contemplated Transactions
         by the Sellers will, directly or indirectly (with or without notice or
         lapse of time):

                           (i) contravene, conflict with, or result in a
                  violation of (A) any provision of the Organizational Documents
                  of the Company, or (B) any resolution adopted by the board of
                  directors or the stockholders of the Company;

                           (ii) contravene, conflict with, or result in a
                  violation or breach of any provision of, or give any Person
                  the right to declare a default or exercise any remedy under,
                  or to accelerate the maturity or performance of, or to cancel,
                  terminate, or modify, any Applicable Contract; or

                           (iii) result in the imposition or creation of any
                  Encumbrance upon or with respect to any of the assets owned or
                  used by the Company.

Except as set forth in Part 3.2 of the Disclosure Letter, neither Sellers nor
the Company is or will be required to give any notice to or obtain any Consent
from any Person in connection with the execution and delivery of this Agreement
by the Sellers or the Company or the consummation or performance of any of the
Contemplated Transactions.

         3.3      CAPITALIZATION

                  The authorized equity securities of the Company consist of
100,000 shares of common stock, par value $1.00 per share, of which 1,000 shares
are issued and outstanding and constitute the Shares. Sellers are and will be on
the Effective Date the record and beneficial owners and holders of the Shares,
and except for the pledge of shares of common stock of the Company owned by
Williams to Mahone, which will be paid off upon Closing, such Shares are free
and clear of all Encumbrances. Mills owns 75 of the Shares; Mahone owns 800 of
the Shares; Wilhite owns 75 of the Shares; and Williams owns 50 of the Shares.

No legend or other reference to any purported Encumbrance appears upon any
certificate representing equity securities of the Company. All of the
outstanding equity securities of the Company have been duly authorized and
validly issued and are fully paid and nonassessable. There are no Contracts
relating to the issuance, sale, or transfer of any equity securities or other
securities of the Company. None of the outstanding equity securities or other

condition and the results of operations of the Company as at the respective
dates of and for the periods referred to in such financial statements, in
accordance with GAAP, subject, in the case of the Interim Balance Sheet, to
normal recurring year-end adjustments (the effect of which will not,
individually or in the aggregate, be materially adverse) and the absence of

the Balance Sheet). No financial statements of any Person other than the Company

         3.5      BOOKS AND RECORDS

                  The books of account, minute books, stock record books, and

Ordinary Course of Business), and all of the properties and assets purchased or
otherwise acquired by the Company since the date of the Balance Sheet (except

quantity usable and salable in the Ordinary Course of Business, except for
obsolete items and items of below-standard quality, all of which have been
written off or written down to net realizable value in the Unaudited Balance
Sheets or the Interim Balance Sheet or on the accounting records of the Company
as of the Effective Date, as the case may be. All inventories not written off
have been priced at the lower of cost or market on a last in, first out basis.
The quantities of each item of inventory (whether raw materials,
work-in-process, or finished goods) are not excessive, but are reasonable in the
present circumstances of the Company.

         3.10     NO UNDISCLOSED LIABILITIES

                  Except as set forth in Part 3.10 of the Disclosure Letter, the

the Interim Balance Sheet and current liabilities incurred in the Ordinary
Course of Business since the respective dates thereof.

         3.11     TAXES

                  (a) The Company has filed or caused to be filed (on a timely

with respect to the Company, pursuant to applicable Legal Requirements. Sellers
have delivered to Buyer copies of, and Part 3.11 of the Disclosure Letter
contains a complete and accurate list of, all such Tax Returns relating to
income or franchise taxes filed since 2002. The Company has paid, or made
provision for the payment of, all Taxes that have or may have become due

Part 3.11 of the Disclosure Letter and are being contested in good faith and as
to which adequate reserves (determined in accordance with GAAP) have been
provided in the Balance Sheet and the Interim Balance Sheet.

                  (b) Part 3.11 of the Disclosure Letter contains a complete and
accurate list of all audits of all such Tax Returns, including a reasonably
detailed description of the nature and outcome of each audit. All deficiencies
proposed as a result of such audits have been paid, reserved against, settled,
or, as described in Part 3.11 of the Disclosure Letter, are being contested in
good faith by appropriate proceedings. Part 3.11 of the Disclosure Letter
describes all adjustments to the United States federal income Tax Returns filed
by the Company or any group of corporations including the Company for all
taxable years since 2000, and the resulting deficiencies proposed by the IRS.
Except as described in Part 3.11 of the Disclosure Letter, neither Sellers or

<PAGE>

                  (c) The charges, accruals, and reserves with respect to Taxes
on the respective books of the Company are adequate (determined in accordance
with GAAP) and are at least equal to the Company's liability for Taxes, with the
exception of Federal Income Taxes which have not been booked due to the Sub
Chapter "S" election (and related pass through tax treatment of shareholders) in
place for the Company through December of 2004. To the Sellers' Knowledge, there
exists no proposed tax assessment against the Company except as disclosed in the
Balance Sheet or in Part 3.11 of the Disclosure Letter. No consent to the
application of Section 341(f)(2) of the IRC has been filed with respect to any
property or assets held, acquired, or to be acquired by the Company. All Taxes
that the Company is or was required by Legal Requirements to withhold or collect
have been duly withheld or collected and, to the extent required, have been paid
to the proper Governmental Body or other Person.

                  (d) All Tax Returns filed by (or that include on a
consolidated basis) the Company are true, correct, and complete. There is no tax
sharing agreement that will require any payment by the Company after the date of
this Agreement. The Company made an election to be treated as an "S" Corporation
upon incorporation, and made an election, effective January 1, 2005 to terminate
the "S" election.

         3.12     NO MATERIAL ADVERSE CHANGE

                  Since the date of the Balance Sheet (a) there has not been any
change in the business, operations, properties, prospects, assets, or condition
of the Company, and (b) no event has occurred or circumstance exists, in either
event that would result in a Material Adverse Effect.

         3.13     EMPLOYEE PLANS

         The Sellers have delivered to the Purchaser a true, correct and
complete list (which is set forth on Part 3.13 of the Disclosure Letter) of all
employee benefit plans of the Company, including all written employment
agreements and all other agreements or arrangements that could obligate the
Company or any Affiliate of the Company to make any severance, change-of-control
or other, similar payments and all deferred compensation agreements, together
with true, correct and complete copies of such plans, agreements and any trusts
related thereto, and classifications of employees covered thereby. Except for
the employee benefit plans, if any, described on Part 3.13 of the Disclosure
Letter, the Company does not sponsor, maintain or contribute to any plan
program, fund or arrangement that constitutes an "employee pension benefit
plan," and the Company does not have any obligation to contribute to or accrue
or pay any benefits under any deferred compensation or retirement funding
arrangement on behalf of any employee or employees (such as, for example, and
without limitation, any individual retirement account or annuity, any "excess
benefit plan" (within the meaning of Section 3(36) of the Employee Retirement
Income Security Act of 1974, as amended "ERISA") or any non-qualified deferred
compensation arrangement). For the purposes of this Agreement, the term
"employee pension benefit plan" shall have the same meaning as is given that
term in Section 3(2) of ERISA. The Company has not sponsored, maintained or
contributed to any employee pension benefit plan, nor is the Company required to
contribute to any retirement plan pursuant to the provisions of any collective
bargaining agreement establishing the terms and conditions of employment of any
of the Company's employees, other than the plans set forth on Part 3.13 of the
Disclosure Letter. The Company is not now, nor as a result of its past
activities can it reasonably be expected to become, liable to the Pension
Benefit Guaranty Corporation (other than for premium payments) or to any multi
employer employee pension benefit plan under the provisions of Title IV of
ERISA. All employee benefit plans listed in Part 3.13 of the Disclosure Letter
and the administration thereof are in substantial compliance with their terms
and all applicable provisions of ERISA and the regulations issued thereunder, as
well as with all other applicable Federal, state and local statutes, ordinances
and regulations. All accrued contribution obligations of the Company or any
subsidiary with respect to any plan listed in Part 3.13 of the Disclosure Letter
have either been fulfilled in their entirety or are fully reflected on the
Unaudited Balance Sheets of the Company.

         COMPLIANCE WITH THE CODE AND ERISA. All employee benefit plans listed
in Part 3.13 of the Disclosure Letter that are intended to qualify under Section
401(a) of the Code (the "Qualified Plans") are, and have been so qualified and
have been determined by the Internal Revenue Service to be so qualified, and
copies of such determination letters are included as part of Part 3.13 of the

Returns) have been timely filed or distributed, and copies thereof are included

an accumulated funding deficiency, as defined in Section 412(a) of the Code and
Section 302(1) of ERISA; and the Company has not incurred (i) any liability for

         Revenue Service;

         (ii) no plan listed in Part 3.13 of the Disclosure Letter that is
         subject to the provisions of Title IV of ERISA has been terminated;

         (iii) there have been no "reportable events" (as that phrase is defined
         in Section 4043 of ERISA) with respect to employee benefit plans listed
         in Part 3.13 to the Disclosure Letter;

         (v) the Company has not incurred liability under Section 4062 of ERISA;
         and

         (vi) To Sellers' Knowledge, no circumstances exist pursuant to which
         the Company could reasonably be expected to have any direct or indirect
         liability whatsoever (including, but not limited to, any liability to
         any multi employer plan or the Pension Benefit Guaranty Corporation
         under Title IV of ERISA or to the Internal Revenue Service for any
         excise tax or penalty, or being subject to any statutory Lien to secure
         payment of any such liability) with respect to any plan now or
         heretofore maintained or contributed to by any entity other than the
         Company that is, or at any time was, a member of a "controlled group"
         (as defined in Section 412(n)(6)(B) of the Code) that includes the
         Company ("Controlled Group").

The transactions contemplated by this Agreement together with any amounts paid
or payable by the Company or any member of the Controlled Group have not
resulted in and will not result in payments to "disqualified individuals" (as
defined in Section 280G(c) of the Code) of the Company or any member of the
Controlled Group which, individually or in the aggregate will constitute "excess
parachute payments" (as defined in Section 280G(b) of the Code) resulting in the
imposition of the excise tax under Section 4999 of the Code or the disallowance
of deductions under Section 280G of the Code.

each such form, report and document complied in all material respects with all
applicable requirements of the Securities Act and the Securities Exchange Act of
1934, as amended, each as then in effect. Since January 1, 2004, at the time of
its filing or effectiveness, no report or registration statement filed by the
Buyer with the SEC contained any untrue statement of a material fact or omitted
to state a material fact necessary to make the statements contained therein, in
light of the circumstances in which they were made, not misleading.

any change or any development or combination of developments which has had or
would reasonably be expected to have a Material Adverse Effect on the Buyer.

reasonably requested by the other party, in connection with the filing of any

the Company, including the following:

<PAGE>

         Such cooperation shall include the retention and (upon the other
party's request) the provision of records and information which are reasonably
relevant to any such tax return, audit, or litigation and making employees
available on a mutually convenient basis to provide additional information and
explanation of any material provided pursuant to this Section 5.1, provided that
the party making any such request will reimburse the party complying with such
request for any reasonable, actual, out-of-pocket costs it has incurred. The
Buyer and the Sellers agree (i) to retain all books and records with respect to
tax matters pertinent to the Company relating to any tax period ending on or
before the Closing Date (the Preclosing Period), and (ii) to give the other
party reasonable notice prior to destroying or discarding any such books and
records and, if the other party so requests, to allow the other party to take
possession of such books and records.

         None of the Sellers, Buyer or the Company shall file, amend or cause
the amendment of any Tax Return of the Company with respect to any Preclosing
Period or agree to an extension of the statute of limitations applicable with
respect to such Tax Return, in each case, without the express prior written
consent of the other parties hereto. Buyer shall promptly forward to Sellers all
notices it receives from the Internal Revenue Service ("IRS") in connection with

         10.7     LIMITATIONS ON AMOUNT--BUYER

                  Buyer will have no liability (for indemnification or
otherwise) with respect to the matters described in Section 10.4 until the total
of all Damages with respect to such matters exceeds $50,000, but then for all

         10.8     EXCLUSIVE REMEDY

                  The indemnification provided for in this Section 10 shall be
the exclusive remedies in any action seeking Damages or any other form of
monetary relief brought by any party to this Agreement against another party
with respect to the representations, warranties, covenants and agreements set
forth in this Agreement; provided that nothing herein shall be construed to
limit the right of any party in a proper case to seek injunctive relief for a
breach of this Agreement. No indemnified party shall be permitted to recover
punitive, consequential, economic or indirect damages from an indemnifying
party, whether by way of indemnification or under any other legal document,

such indemnified party will, if a claim is to be made against an indemnifying
party under such Section, give notice to the indemnifying party of the
commencement of such claim, but the failure to notify the indemnifying party
will not relieve the indemnifying party of any liability that it may have to any
indemnified party, except to the extent that the indemnifying party demonstrates
that the defense of such action is prejudiced by the indemnifying party's
failure to give such notice.


                                       38
<PAGE>

                  (b) If any Proceeding referred to in Section 10.9(a) is
brought against an indemnified party and it gives notice to the indemnifying
party of the commencement of such Proceeding, the indemnifying party will be
entitled to participate in such Proceeding and, to the extent that it wishes
(unless (i) the indemnifying party is also a party to such Proceeding and the
indemnified party determines in good faith that joint representation would be
inappropriate, or (ii) the indemnifying party fails to provide reasonable
assurance to the indemnified party of its financial capacity to defend such
Proceeding and provide indemnification with respect to such Proceeding), to
assume the defense of such Proceeding with counsel reasonably satisfactory to
the indemnified party and, after notice from the indemnifying party to the
indemnified party of its election to assume the defense of such Proceeding, the
indemnifying party will not, as long as it diligently conducts such defense, be
liable to the indemnified party under this Section 10 for any fees of other
counsel or any other expenses with respect to the defense of such Proceeding, in
each case subsequently incurred by the indemnified party in connection with the
defense of such Proceeding, other than reasonable costs of investigation. If the
indemnifying party assumes the defense of a Proceeding, (i) no compromise or
settlement of such claims may be effected by the indemnifying party without the
indemnified party's consent unless (A) there is no finding or admission of any
violation of Legal Requirements or any violation of the rights of any Person and
no effect on any other claims that may be made against the indemnified party,
and (B) the sole relief provided is monetary damages that are paid in full by
the indemnifying party; and (ii) the indemnified party will have no liability
with respect to any compromise or settlement of such claims effected without its
consent. If notice is given to an indemnifying party of the commencement of any
Proceeding and the indemnifying party does not, within ten business days after
the indemnified party's notice is given, give notice to the indemnified party of
its election to assume the defense of such Proceeding, the indemnified party may
retain its own legal counsel at the indemnifying party's expense until such time
as the indemnifying party agrees to assume such defense.

                  (c) Notwithstanding the foregoing, if an indemnified party
determines in good faith that there is a reasonable probability that a
Proceeding may adversely affect it or its affiliates other than as a result of
monetary damages for which it would be entitled to indemnification under this
Agreement, the indemnified party may, by notice to the indemnifying party,
assume the exclusive right to defend, compromise, or settle such Proceeding at
its sole cost and expense, but the indemnifying party will not be bound by any
determination of a Proceeding so defended or any compromise or settlement
effected without its consent (which may not be unreasonably withheld).

         10.10    PROCEDURE FOR INDEMNIFICATION--OTHER CLAIMS

                  A claim for indemnification for any matter not involving a
third-party claim may be asserted by notice to the party from whom
indemnification is sought.

right unless in writing signed by the other party; (b) no waiver that may be
given by a party will be applicable except in the specific instance for which it

notice or demand to take further action without notice or demand as provided in
