                    ARTICLE 4. REPRESENTATIONS AND WARRANTIES
                            OF SELLER AND SHAREHOLDER

      SECTION 4.1 Seller and Shareholder, jointly and severally, represent and
warrant to Buyer that:

            (a)   AUTHORITY.

                  (i) Seller is a duly organized and validly existing South
            Carolina corporation, duly qualified or authorized to do business in
            the State of South Carolina and in each jurisdiction in which such
            qualification or authorization is required except where failure to
            be so qualified or licensed would not have a material adverse effect
            on the Assets or the Business. The execution and delivery of this
            Agreement, the consummation of the transactions contemplated hereby
            and the compliance by Seller and Shareholder with the terms of this
            Agreement do not and will not conflict with or result in a breach of
            any terms of, or constitute a default under, the Articles of
            Incorporation or Bylaws of Seller, or any instrument or other
            agreement to which Seller or Shareholder is a party or by which
            Seller or Shareholder, or any of their respective properties or
            assets, is bound. This Agreement constitutes a valid obligation of
            Seller and Shareholder enforceable against Seller and Shareholder in
            accordance with its terms except as may be limited by applicable
            bankruptcy, insolvency, moratorium or similar laws of general
            application relating to or affecting creditor's rights generally and
            except for the limitations imposed by general principles of equity.

                  (ii) Shareholder is competent, under no duress or legal
            restraint, and has all necessary authority to enter into this
            Agreement, perform Shareholder's obligations hereunder and
            consummate the transactions contemplated hereby.

                  (iii) Seller has the full power and authority to enter into
            this Agreement and to consummate the transactions contemplated
            hereby. Seller has taken all action necessary to approve the sale of
            the Assets to Buyer, including Shareholder approvals, if necessary,
            and except as otherwise set forth herein, no other authorization or
            approval is required for any of the foregoing.

                  (iv) All of the issued and outstanding shares of capital stock
            of Seller are owned of record and beneficially by the Shareholder,
            free and clear of all liens, security interests and encumbrances
            whatsoever.

                  (v) Seller does not have any subsidiaries or any other equity
            interest in any limited liability company, corporation, partnership
            or similar entity.

            (b) COMPLIANCE WITH LAW. To Seller's knowledge, neither Seller nor
      any Shareholder is in default under any applicable federal, state or local
      laws, statutes,

                                                                   Page 10 of 34
<PAGE>

      ordinances, permits, licenses, orders, approvals, variances, rules or
      regulations or judicial or administrative decisions ("Applicable Laws")
      which would have a material adverse effect upon the Assets or the
      Business. Seller has been granted all material licenses, permits,
      consents, authorizations and approvals from federal, state and local
      government regulatory bodies necessary or desirable to carry on the
      Business, all of which are currently in full force and effect. To Seller's
      knowledge, the operation, conduct and ownership of the properties, assets
      and Business of Seller are being, and at all times have been, conducted in
      compliance with all Applicable Laws in all material respects. No notice
      from any governmental body has been served upon or given to Seller
      claiming that the Business or any of the Assets is not in conformity with
      any Applicable Law.

            (c) EQUIPMENT. Listed on Schedule 1.1(a) hereto is a complete and
      accurate list of all Equipment used or for use in connection with the
      Business. In the aggregate, the Equipment including the Rolling Stock is
      sufficient to conduct the business as historically conducted.

            (d) ROLLING STOCK. Listed on Schedule 1.1(b) hereto is a complete
      and accurate list of all Rolling Stock.

            (e) CONTRACTS AND LEASES. Listed on Schedule 4.1(e) hereto is a
      complete and accurate list of all of the Contracts as of the date hereof
      (i) with all Customers from which five percent (5%) or more of the
      Business' average monthly revenue is derived, or (ii) other than customer
      agreements entered into in the ordinary course of business by which the
      Seller is or the Assets are bound. Also listed on Schedule 4.1(e) hereto
      is a complete and accurate list of all of the leases as of the date hereof
      which will be assumed by Buyer (the "Assumed Leases"). Except to the
      extent consent to assignment may be required as indicated in Section 1.3
      and except as set forth on Schedule 4.1(e), all Contracts and Assumed
      Leases are (and unless terminated by a party in accordance with its terms
      will be immediately following the Closing) in full force and effect and
      are valid, binding and enforceable against the respective parties thereto
      in accordance with their respective provisions. Seller is not in material
      default under any of the Contracts or Assumed Leases; nor has there
      occurred an event or condition (including Seller's execution and delivery
      of or performance under this Agreement) which with the passage of time or
      the giving of notice (or both) would constitute a material default under
      any obligation under any of the Contracts or Assumed Leases; no claim of
      such a default has been asserted and there is no reasonable basis upon
      which such a claim could validly be made. To the best of the Seller's and
      Shareholder's knowledge, no person intends or desires to modify, waive,
      amend, rescind, release, cancel or terminate any of the Contracts or
      Assumed Leases; provided the foregoing shall not be construed to apply to
      any termination of a temporary rolloff which although the arrangement may
      be subject to a written trip ticket which contains contractual provisions
      does not have a specified term and by its nature is a temporary
      arrangement which may end at any time. Notwithstanding the foregoing,
      nothing in this Section 4.1(e) or otherwise in this Agreement shall be
      construed as a guaranty or warranty that any of the customers of the
      Business, including without limitation those operating under oral
      arrangements will continue to purchase services after the Closing.

                                                                   Page 11 of 34
<PAGE>

            (f) TITLE TO THE PERSONAL PROPERTY ASSETS. Except for liens securing
      the obligations described in Section 7.2(d), Seller has good and
      marketable title to all of the Assets which consists of items of personal
      property (the "Personal Property Assets"), and at Closing all such
      Personal Property Assets will be free and clear of all liens,
      encumbrances, security interests, equities or restrictions whatsoever,
      direct or indirect, accrued, absolute, contingent or otherwise and, by
      virtue of the grant, conveyance, sale, transfer, and assignment of the
      Personal Property Assets hereunder. Except for liens securing the
      obligations described in Section 7.2(d), Buyer shall receive good and
      marketable title to the Personal Property Assets, free and clear of all
      liens, lease payments (including lease-end buy-out payments),
      encumbrances, security interests, equities or restrictions whatsoever
      other than liens for taxes not yet due and payable.

            (g) TITLE TO OPERATIONS PROPERTY. Seller currently operates the
      Business on the real property listed on Schedule 4.1(g). (the "Operations
      Property"). Except as set forth on Schedule 4.1(g), Seller has never
      owned, leased or otherwise occupied, had an interest in or operated any
      real property other than the Operations Property. Except as set forth on
      Schedule 4.1(g);

                  (i) Seller has good and marketable fee simple title to the
            Operating Property, free and clear of all liens and encumbrances
            other than (i) utility easements, restrictive covenants and minor
            imperfections of title, if any, none of which materially detracts
            from the value or impairs the present use of the Operations Property
            subject thereto or impairs the present operations of the Business
            and each as set forth more fully on Schedule 4.1(g), (ii) liens and
            encumbrances of record and which would be observable upon a physical
            inspection of the Operations Property and riparian rights of
            landowners who are downstream of the stream which crosses the
            Operating Property, (iii) zoning laws and other land use
            restrictions that do not impair the present use of the Operations
            Property subject thereto, and (iv) encumbrances related to taxes not
            yet due or payable or that are being contested in good faith and for
            which appropriate reserves have been taken (the encumbrances
            described in clauses (i), (ii), (iii) and (iv) being referred to
            collectively as the "PERMITTED ENCUMBRANCES") and (v) encumbrances
            which will be released at or prior to the Closing. There is no
            pending or, to the knowledge of Seller, threatened legal action
            alleging any zoning violations, or affecting any portion or all of
            the Operations Property, including any condemnation action, and
            Seller does not know of any basis for such action.

                  (ii) Seller does not own or hold, and is not obligated under
            or a party to, any option, right of first refusal or other
            contractual right to purchase, acquire, sell or dispose of the
            Operations Property or any portion thereof or interest therein.

                  (iii) Seller does not owe any money to any architect,
            contractor, subcontractor or materialmen for labor or materials
            performed, rendered or supplied to or in connection with the
            Operations Property, and there is no construction or other
            improvements work being done at and there are no

                                                                   Page 12 of 34
<PAGE>

            construction or other improvement materials being supplied to the
            Operations Property.

                  (iv) The Operations Property is, and at all times during
            operation of the Business has been, fully licensed, permitted and
            authorized for the operation of the Business under all Applicable
            Laws relating to the protection of the environment, the Operations
            Property and the conduct of the Business thereon (including, without
            limitation, all zoning restrictions and land use requirements)
            except where the failure to be so licensed, permitted or authorized
            would not have a material adverse effect on the Business or Assets.

                  (v) Neither Seller, Shareholder nor the Operations Property
            (with respect to activities of Seller) now is or ever has been
            involved in any litigation or administrative proceeding seeking to
            impose fines, penalties or other liabilities or seeking injunctive
            relief for violation of any Applicable Laws relating to the
            environment.

                  (vi) There have been no material spills, leaks, deposits or
            other releases of Hazardous Materials into or onto the Operations
            Property by Seller.

                  (vii) Except as permitted by law, the Operations Property does
            not contain any underground or above-ground storage tanks or
            transformers containing Hazardous Materials, petroleum products or
            wastes or other hazardous substances regulated by 40 CFR 280 or
            other Applicable Laws which were placed on the Operations Property
            by Seller or to its knowledge by any third party. All above and
            below ground tanks currently in use on the Operations Property are
            being used and maintained in accordance with all Applicable Laws.

            (h) LITIGATION. Except as set forth on Schedule 4.1(h) hereof,
      Seller has no knowledge of any claim (including Notices of Violation),
      litigation, action, suit or proceeding, administrative or judicial,
      pending or threatened against Seller or Shareholder, or involving the
      Assets or the Business, at law or in equity, before any federal, state or
      local court or regulatory agency, or other governmental authority. Neither
      Seller nor Shareholder has any knowledge of any of the above, and neither
      Seller nor Shareholder has any knowledge of any facts or circumstances
      that exist which would, with the passage of time or giving of notice (or
      both), give rise to any of the above.

            (i) EMPLOYEES. Attached as Schedule 4.1(i) hereof is a complete list
      of all employees of the Business and their respective rates of
      compensation (including a breakdown of the portion thereof attributable to
      salary, bonus and other compensation, respectively) as of the date of
      Closing. Each employee is an employee at will and there are no other
      collective bargaining agreements affecting any employee of Seller. There
      is no pending or, to the best of Seller's and Shareholder's knowledge,
      threatened labor dispute involving Seller and any group of its employees
      nor has Seller experienced any labor interruptions over the past three
      years. Shareholder will cause Seller to terminate each of its employees as
      of the close of business on the Closing Date. Buyer agrees to employ such
      former employees of Seller as Buyer deems appropriate, provided that each
      such person seeking employment meets the qualifications established by
      Buyer. Except as set forth in 26 CFR 54.4980B-9, it is expressly
      understood that Buyer shall not assume

                                                                   Page 13 of 34
<PAGE>

      or be responsible for any severance or other employee benefit arising out
      of an individual's employment by Seller prior to the Closing Date. Nothing
      herein will be deemed to give any individual a right of employment and
      Buyer shall not be obligated to hire any of Seller's employees.

            (j) EMPLOYEE RELATIONS AND BENEFIT PLANS. Set forth on Schedule
      4.1(j) is an accurate and complete list of all agreements of any kind
      between Seller and its employees or group of employees, including, without
      limitation, employment agreements, collective bargaining agreements and
      benefit plans. Except as set forth in 26 CFR 54.4980B-9 Buyer shall not,
      by the execution and delivery of this Agreement or otherwise, become
      obligated to or assume any liabilities or contractual obligations with
      respect to any employee of Seller or otherwise become liable for or
      obligated in any manner (contractual or otherwise) to any employee of
      Seller, including, without limiting the generality of the foregoing, any
      liability or obligation pursuant to any collective bargaining agreement,
      employment agreement, or pension, profit sharing or other employee benefit
      plan (within the meaning of Section 3(3) of the Employment Retirement
      Income Security Act of 1974, as amended) or any other fringe benefit
      program maintained by Seller or to which Seller contributes or any
      liability for the withdrawal or partial withdrawal from or termination of
      any such plan or program by Seller.

            (k) FINANCIAL STATEMENTS. Schedule 4.1(k) attached hereto contains
      the following financial statements of Seller (collectively, the "Unaudited
      Financials"): (a) unaudited balance sheets and statements of operations as
      of and for the fiscal years ended September 30, 2002, September 30, 2003,
      and September 30, 2004, and (b) the unaudited balance sheet (the "Most
      Recent Balance Sheet") and statements of operations as of and for the one
      (1) month ended October 31, 2004 (the "Balance Sheet Date"). The Unaudited
      Financials have been prepared in accordance with accounting principles
      consistently applied with during prior periods, are complete and correct
      in all material respects and fairly present the financial condition and
      results of the operation of Seller as of the dates and for the periods
      indicated thereon, and contain and reflect adequate reserves for all
      material liabilities and obligations of Seller of any nature, whether
      absolute, contingent or otherwise, except for liabilities and obligations
      which are not required to be stated and reserves not required to be
      maintained under Generally Accepted Accounting Principles and except in
      the case of Unaudited Financials covering interim periods to year end
      adjustments, the net effect of which shall not be material in nature or
      amount. Except as may be noted thereon, the statements of income included
      in the Unaudited Financials do not contain any material items of
      extraordinary or nonrecurring income or any other income not earned in the
      ordinary course of business. Except as set forth on Schedule 4.1(k), the
      books of account of Seller have been maintained in all material respects
      in accordance with prudent business practices.

            (l) ABSENCE OF CERTAIN CHANGES. Except as disclosed in the Unaudited
      Financials or on Schedule 4.1(l), since the Balance Sheet Date, there has
      not occurred:

                  (i) Any adverse change in the assets, liabilities (whether
            absolute, accrued, contingent or otherwise), condition (financial or
            otherwise), results of operations, business or prospects of Seller
            not reflected in the Unaudited

                                                                   Page 14 of 34
<PAGE>

            Financials which are specific to Seller and not general to business
            or inventory which would involve a one-time loss or a loss of
            revenue during a twelve-month period of in excess of $10,000;

                  (ii) Any cancellation of an existing Customer Contract
            (written or oral) with respect to which the customer is obligated to
            pay in excess of $5,000 per month. (Buyer acknowledges that there
            can be inconsistent revenue streams due to the cyclical nature of
            temporary construction sites and other non-contract temporary
            customers.);

                  (iii) Except for changes in the ordinary course of business
            consistent with past practices, any amendment or modification of any
            material Contract, or any termination of any agreement that would
            have been a material Contract were such agreement in existence as of
            the date hereof;

                  (iv) Any increase in the compensation (including, without
            limitation, the rate of commissions) payable to, or any payment of a
            cash bonus to, any officer, director or employee of, or consultant
            to, Seller;

                  (v) Any transaction by Seller, whether or not covered by the
            foregoing, not in the ordinary course of business and not consistent
            with past practices;

                  (vi) Any alteration in the manner of keeping the books,
            accounts or records of Seller, or in the accounting practices
            therein reflected;

                  (vii) Any acquisition or redemption by Seller of any of its
            equity securities or any loan by Seller to any of its security
            holders or partners as applicable;

                  (viii) [Intentionally Deleted]

                  (ix) Any damage or destruction to, or loss of, any assets or
            property owned, leased or used by Seller (whether or not covered by
            insurance) in excess of $5,000; and Seller has not:

                  (x) created or permitted the creation or imposition of any
            security interest upon any of the Assets, except for security
            interests arising by operation of law or in the ordinary course of
            Seller's business and which will terminate at Closing;

                  (xi) waived any of its rights or claims that singly or in the
            aggregate are material to the Business;

                                                                   Page 15 of 34

      Seller has never owned, operated, had an interest in, engaged in and/or

      list. To Seller's actual knowledge, neither Seller nor Shareholder is
      listed as a potentially responsible party under CERCLA or any comparable
      or similar South Carolina statute; to Seller's knowledge, neither Seller
      nor Shareholder has received any notice of such a listing; and to Seller's
      knowledge, neither Seller nor Shareholder knows of any facts or
      circumstances which could give rise to such a listing.

            (o) GOVERNMENT NOTICES; PERMITS; INTANGIBLE RIGHTS. Seller has
      delivered to Buyer on Schedule 4.1(o) an accurate list and summary
      description as of the Closing Date of all of its certificates of need,

      certificates, trademarks, trade names, patents, patent applications and
      registered copyrights owned or held by Seller with respect to the Assets,
      all of which are valid, in good standing and in full force and effect.
      Except as set forth on Schedule 4.1(o), such permits, titles, licenses,
      orders, approvals, franchises, certificates, trademarks, trade names,

      notifications from such governmental agencies, with respect to the Assets
      which are in its possession where such filings are related to motor
      vehicles, fuel or environmental matters. Buyer agrees to maintain such
      records for not less than the time required by law for Buyer or Seller to
      maintain such records. Notwithstanding, the foregoing Seller shall retain
      all fuel receipts but shall provide reasonable access thereto to Buyer
      upon

                                                                   Page 17 of 34

      any employee, agent or other person acting on Seller's behalf, directly or
      indirectly, given or agreed to give any gift or similar benefit to any

      (domestic or foreign) that would subject Seller to any damage or penalty
      in any civil, criminal or governmental litigation or proceeding.

            (s) TRANSACTIONS WITH RELATED PARTIES. Except as set forth on

      been no transactions by Seller with (x) any member of Shareholder's
      family, (y) any person or legal entity that is directly or indirectly
      controlled by Shareholder or one or more members of Shareholder's family,
      or (z) any person or legal entity that directly or indirectly controls, is
      directly or indirectly controlled by, or is directly or indirectly under
      common control with Seller (those identified in (x) through (z) above
      being referred to collectively as a "Related Party"), and (ii) there are
      no written agreements now in effect between Seller and any Related Party.
      In addition, none of the transactions with Shareholder or any Related
      Party that have occurred has provided to Seller assets, income, financing
      or business on a basis significantly more or less favorable than that
      available from unaffiliated persons. Schedule 4.1(s) also (i) states the
      amounts due from Seller to any Related Party and the amounts due from any
      Related Party to Seller, (ii) describes the transactions out of which such
      amounts due arose, and (iii) describes any interest of Seller or any
      Related Party in any supplier or customer of, or any other entity that has
      had business dealings with, Seller. After the Closing, except as set forth
      on Schedule 4.1(s), there will be no obligations or other liabilities
      between Buyer, on the one hand, and Seller or any Related Party, on the
      other hand, other than pursuant to this Agreement.

            (t) INSURANCE. Attached to Schedule 4.1(t) is a complete set of
      copies of all insurance policies or certificates regarding same and of all
      claims made by Seller on any liability or other insurance policies during
      the past five years, and loss runs for the past five years. Schedule
      4.1(t) is a complete list of all insurance currently in place over the
      three years preceding the Closing, and accurately sets forth the types of
      coverages, deductible amounts, carriers and expiration dates thereof.
      Except as included in Schedule 4.1(t), no notice or other communication
      has been received by the Seller from any insurance company within the
      three years preceding the Closing canceling or threatening to cancel the
      insurance policies.

                                                                   Page 18 of 34
<PAGE>

            (u) ABSENCE OF UNDISCLOSED LIABILITIES. There are no material
      liabilities of Seller, whether absolute, accrued, contingent or otherwise,
      and whether due or to become due, not reflected on or reserved for in the
      Unaudited Financials, as applicable, except for executory obligations
      under contracts including those not assigned to Buyer in connection
      herewith, immaterial Contracts for the purchase of supplies or the sale of
      products incurred in the ordinary course of business. There are no
      commitments, Contracts or undertakings covering purchases in excess of

      person, corporation, partnership, joint venture, association, organization

            (x) LETTERS OF CREDIT, BONDS, ETC.

                  (i) Except as disclosed in Schedule 4.1(x), Seller is not the
            beneficiary of any letters of credit, performance or other bonds, or
            any other financial instruments guaranteeing the payment or
            performance of any third party under any Contract; and

                  (ii) Except as disclosed in Schedule 4.1(x), Seller is not
            required to provide any letter of credit, performance or other bond,
            or any other financial instrument for the purpose of guaranteeing
            the Seller's payment or performance under any Contract.

            (y) COMPLETENESS OF DISCLOSURE. This Agreement and the Schedules
      hereto and to the knowledge of Seller all other material written
      information and documents furnished to Buyer and its representatives and
      upon which Buyer can demonstrate that it relied and as a result of such
      reliance was damaged do not and will not include any untrue statement of a
      material fact or omit to state a material fact necessary to make the
      statements therein not misleading. If either Seller or Shareholder becomes
      aware of any fact or circumstance which would change a representation or
      warranty of Seller or Shareholder in this Agreement, the party with such
      knowledge shall immediately give notice of such fact or circumstance to
      Buyer. However, such notification shall not relieve Seller or Shareholder
      of his, her or its respective obligations under this Agreement, and at the
      sole option of Buyer, the truth and accuracy of any and all warranties and
      representations of Seller and Shareholder at the date of this Agreement
      shall be a precondition to the consummation of this transaction.

                                                                   Page 19 of 34

      SECTION 4.2 SURVIVAL. Each of the representations and warranties set forth
in this Article 4 shall survive the Closing and the transfer of the Assets for
the period of time and as more fully set forth in Section 8.6 hereof.

                 ARTICLE 5. COVENANTS OF SELLER AND SHAREHOLDER

      SECTION 5.1 TRANSITION OPERATIONS. From and after the Closing until the
period of the noncompete provisions set forth in Section 5.2 have terminated,
neither Seller nor Shareholder will take any action that is designed or intended
to have the effect of discouraging any customer or business associate of Seller
from maintaining the same business relationships with Buyer after the Closing
that it maintained with Seller before the Closing. Specifically, and without
limitation, after the Closing until the period of the non compete provisions set
forth in Section 5.2 have terminated, Seller and Shareholder will:

            (a) Refer all customer inquiries relating to the Business to Buyer;
      and

            (b) For a period of 120 days following the date of Closing, without
      additional consideration, assist Buyer with the orderly transition of the
      operations of the Business from Seller to Buyer. Such assistance shall
      include, without limitation, assisting Buyer in obtaining contracts with
      current customers, routing transition activities and developing sufficient
      information to allow Buyer to compile accurate customer billings, and
      immediately upon receipt, deliver original certificates of title and/or
      registrations with respect to the Rolling Stock and the Equipment, duly
      endorsed by Seller to Buyer. The foregoing is not intended to require
      Shareholder to maintain regular office hours or work on anything other
      than a part-time basis. Any and all costs or expenses incurred by Seller
      or Shareholder including travel expenses in connection with the foregoing
      shall be paid by Buyer.

            (c) For the initial period of 30 days following the Closing within
      the 120 day period described above, Shareholder shall assist Buyer on a
      full-time basis for consideration of $2,000 payable during such period.

      SECTION 5.2 NONCOMPETITION.

            (a) For a period of *** after the Closing, except as set forth in
      the following paragraph, neither (i) Seller, nor (ii) Shareholder, shall
      for any reason whatsoever, directly or indirectly, for itself or himself
      or on behalf of or in conjunction with any other person, company,
      partnership, corporation or business of whatever kind or nature engage, as
      an officer, director, shareholder, owner, manager, Shareholder, partner,
      joint venturer, lender or in any other capacity, whether as an employee,
      independent contractor, consultant, advisor, agent or otherwise, or as a
      sales representative, of any business in direct or indirect competition
      with Buyer located or operating within *** (the "Territory"). For purposes
      of this Agreement, the term "Affiliate" shall mean in respect of any
      specified party, any other person or legal entity that, directly or
      indirectly, controls, is controlled by, or is under common control with,
      such specified party or if such specified party.

      Notwithstanding the foregoing provisions of this paragraph (a) Seller and
      the Shareholder may be a passive investor owning no more than five percent
      (5%) of the outstanding

                                                                   Page 20 of 34
<PAGE>

      equity securities (including, but not limited to, debt or other
      obligations that are convertible into equity securities) of any
      corporation or other entity the equity securities of which are listed on a
      national securities exchange or traded on the NASDAQ National Market
      System and with which such persons have no other connection whatsoever.

            (b) For a period of *** after the Closing Date, neither Seller nor
      Shareholder shall offer to employ any person who is, at that time, or who
      has been known by Shareholder to have been within one (1) year prior to
      that time, an employee of the Business.

            (c) For a period of *** after the Closing Date, neither Seller nor
      Shareholder shall engage or participate in any effort or act to solicit or
      induce any customer, supplier, associate, employee, sales or other agent,
      independent contractor or other person that has a business relationship
      with the Business, within the Territory, or which has been a customer,
      supplier, employee, sales or other agent, independent contractor, or other
      person in a business relationship with the Business, Buyer or any of
      Buyer's Affiliates within the Territory within *** prior to that time, to
      discontinue such relationship with the Business.

            (d) Seller and Shareholder acknowledge that the damages that would
      be suffered by Buyer as a result of any breach of the provisions of this
      Section 5.2 may not be calculable and that an award of a monetary judgment
      for such a breach would be an inadequate remedy. Consequently, Buyer shall
      have the right, in addition to any other rights it may have, to obtain, in
      any court of competent jurisdiction, injunctive relief to restrain any
      breach or threatened breach of any provision of this Section 5.2 or
      otherwise to specifically enforce any of the provisions hereof, and Buyer
      shall not be obligated to post a bond or other security in seeking such
      relief. This remedy is in addition to damages directly or indirectly
      suffered by Buyer or its Affiliate and if the court or other tribunal
      determines that the breach or threatened breach was material and it is
      otherwise equitable, reasonable attorneys fees.

            (e) Each of Seller and Shareholder hereby acknowledges and agrees
      that a part of the consideration for the agreements contained in this
      Section 5.2 is the aggregate of the direct and indirect benefits that each
      of Seller and Shareholder are receiving under this Agreement and the
      Auxiliary Agreement, including but not limited to the Purchase Price paid
      by Buyer. Each of Seller and Shareholder further acknowledges and agrees
      that this Agreement contains reasonable limitations as to the time,
      geographical area, and scope of activity to be restrained, and does not
      impose a greater restraint than is necessary to protect the goodwill and
      other legitimate business interests of Buyer, the value of the Assets and
      the Business acquired by Buyer. Therefore, each of Seller and Shareholder
      agrees that all restrictions are fairly compensated for and that no
      unreasonable restrictions exist. In the event that any court of competent
      jurisdiction finally determines that the time period, scope or the
      geographic area of any covenant contained in this Section 5.2 is
      unreasonable or excessive and any such covenant is to that extent made
      unenforceable, the parties agree that the restrictions contained in this
      Section 5.2 shall remain in full force and effect for the greatest time
      period and scope and within the greatest geographic area as is permissible
      without rendering such covenant unenforceable. The parties intend that
      each of the covenants contained in Sections 5.2(a), (b), (c) and (d) shall
      be deemed to

                                                                   Page 21 of 34
<PAGE>

      constitute separate covenants. The parties further agree that the
      consideration paid to the Seller hereunder is paid for the benefit of
      Shareholder, that Shareholder will derive substantial benefits therefrom
      and, therefore, the covenants contained in this Section 5.2 are binding
      upon Shareholder.

            (f) All of the covenants contained in this Section 5.2 shall be
      construed as an agreement independent of any other provision of this
      Agreement, and the existence of any claim or cause of action of either
      Seller or Shareholder against Buyer, whether predicated on this Agreement
      or otherwise, shall not constitute a defense to the enforcement by Buyer
      of such covenants.

            (g) Each of Seller and Shareholder agrees that the covenants
      contained in this Section 5.2 are a material and substantial part of this
      transaction.

            (h) Because of the difficulty of measuring economic losses as a
      result of the breach of the foregoing covenants, and because of the
      immediate and irreparable damage that would be caused for which it would
      have no other adequate remedy, Buyer and each of Seller and Shareholder
      agrees that, in the event of a breach by either of Seller or Shareholder
      of any of the covenants contained in this Article 5, such covenant or
      covenants may be enforced against each of Seller and each Shareholder by
      injunctions and restraining orders.

            (i) Notwithstanding the above, in the event there is a default under
      the Convertible Note, and such default continues for ten (10) business
      days after written notice thereof, the provision of this Section 5.2 shall
      terminate for all time.

      SECTION 5.3 AUDIT ASSISTANCE. Buyer, at its own cost and expense, may
engage external auditors to audit Seller's financial records relating to the
Business (including up to three years of historical data). Seller agrees to take
all commercially reasonable efforts (at Buyer's cost) to cooperate with any such
audit and to assist in the completion of such audit, including, without
limitation, by providing, executing and acknowledging all such documents that
are necessary to complete the audit (including having Seller's financial records
converted, for Buyer's use only, to accrual based accounting financials in
accordance with GAAP), and by making any representations regarding the Business
and Seller's financial records, as may be reasonably requested by Buyer or the
external auditors and which Seller reasonably believes are accurate.

      SECTION 5.4 SURVIVAL. Each of the covenants set forth in Sections 5.1 and
5.3 shall survive the Closing, the transfer of the Assets, the Bill of Sale and
all other documents, instruments or agreements relating to the transactions
contemplated herein as set forth in Section 8.7. Each of the covenants set forth
in Section 5.2 shall survive the Closing, the transfer of the Assets, the Bill
of Sale and all other documents, instruments or agreements relating to the
transactions contemplated herein as set forth in Section 5.2.

               ARTICLE 6. REPRESENTATIONS AND WARRANTIES OF BUYER

      SECTION 6.1 Buyer represents and warrants to the Seller that:

                                                                   Page 22 of 34

      Delaware limited liability company, duly qualified or authorized to carry
      on its business in the places and in the manner as now conducted except
      for where the failure to be so authorized, qualified or licensed would not
      have a material adverse affect on its business.

            (b) Execution. Subject to receipt of the approval of WCA's and
      Buyer's Board of Directors, (i) the execution, delivery and performance of
      this Agreement and the transactions contemplated hereby are duly and
      validly authorized by all requisite corporate action on the part of Buyer
      and WCA, and (ii) this Agreement constitutes the legal, valid and binding
      obligation of Buyer and WCA enforceable in accordance with its terms,
      except as may be limited by applicable bankruptcy, insolvency, moratorium
      or similar laws of general application relating to or affecting creditor's
      rights generally and except for the limitations imposed by general
      principles of equity.

            (c) Conformity with Law. Buyer and WCA have the power and right to
      enter into and perform this Agreement and the transactions contemplated
      herein. Neither Buyer's nor WCA's execution of this Agreement nor the
      consummation of the transactions contemplated herein violate or conflict
      with (i) any law, rule, regulation, ordinance or decree applicable to
      Buyer or WCA; (ii) any provision of Buyer's Certificate of Organization or
      Limited Liability Company Agreement; (iii) any provision of WCA's
      Certificate of Incorporation or By-Laws; or (iv) any material agreement or
      instrument to which Buyer or WCA is a party or by which it is bound.

            (d) Due Diligence.

            (i) Buyer has knowledge and experience in financial and business
      matters and is capable of evaluating the merits and risks of the
      transaction contemplated by this Agreement. Buyer confirms that
      Shareholder has provided to the Buyer the opportunity to ask questions of
      the management of the Seller and to acquire such additional information
      about Seller and financial condition of Seller as the Buyer requested, and
      to Buyer's knowledge, all such information has been received. Buyer
      further acknowledges that neither Seller nor any Shareholder, director,
      officer, employee, or agent has made any warranty, express or implied, as
      to the future profitability of the Business for Buyer, or with respect to
      any forecasts, projections, or business plans prepared by or on behalf of
      Seller or Shareholder and delivered to Buyer in connection with the
      Business and the negotiation and the execution of this Agreement.

            (ii) Buyer is not aware of any inaccuracies of representations and
      warranties of Seller under this Agreement. To the extent that Buyer has
      become aware of any such inaccuracies prior to Closing (through its due
      diligence or otherwise), Seller shall have no obligation to indemnify
      Buyer under this Agreement.

      SECTION 6.2 SURVIVAL. Each of the representations and warranties set forth
in this Article 6 shall survive the Closing and the transfer of the Assets.

                                                                   Page 23 of 34

destruction of any property, whether based on negligence, breach of warranty, or

                                                                   Page 24 of 34

by that certain First Amendment to Disposal Agreement dated June 29, 2000 ((a)
through (r) being referred to collectively as the "Retained Liabilities"). The
Seller shall retain all of the Retained Liabilities. The assumption of the
Assumed Liabilities by Buyer hereunder shall not in any respect enlarge any
rights of third parties under contracts or arrangements with Buyer or Seller and
nothing herein shall prevent any party from contesting in good faith any of the
Assumed Liabilities with any third party. Seller agrees to indemnify Buyer and
its successors and assigns from and against any liabilities or obligations
related to any Retained Liabilities in accordance with Section 8.1 hereof.

      SECTION 7.2 ASSUMPTION OF SPECIFIC LIABILITIES. At the Closing, Buyer

            (e) any material misrepresentation in, or omission from, any
      Schedule to this Agreement;

            (f) any liability of any of Seller or Shareholder imposed upon Buyer
      as a result of any of Seller or Shareholder's failure to qualify for an
      exemption from, and obtain the protection afforded by compliance with, the
      notification requirements of, the bulk transfer or sales laws in force in
      such jurisdictions in which such laws may be applicable to any of Seller
      or Shareholder or the transactions contemplated under this Agreement;

            (g) any liability of any of Seller or Shareholder resulting from one
      or more pending or threatened lawsuits, whether or not listed on Schedule
      4.1(h);

            (h) any liability to, or asserted by, any employee or former

      United States Bankruptcy Code or otherwise;

            (j) all taxes of any of Seller or Shareholder for all taxable

      a result of the consummation of the transactions contemplated hereunder,
      together with any expenses (including, without limitation, settlement
      costs and any attorneys', accountants' and consultants' fees and other
      expenses) incurred in connection with the contesting, collection or
      assessment of such taxes; and

                                                                   Page 26 of 34

action, damage, liability, expense or other cost, or to have paid or to have
become obligated to pay any sum on account of the matters referred to in
subparagraphs (a) - (m) of this Section 8.1 if the same shall be suffered, paid
or incurred by Buyer, or any parent, subsidiary, affiliate, or successor of
Buyer, as applicable. The amount of the loss, claim, action, cause of action,
damage, liability, expense or other cost deemed to be suffered, paid or incurred
by Buyer shall be an amount equal to the loss, claim, action, cause of action,
damage, liability, expense or other cost suffered, paid or incurred by such
parent, subsidiary, affiliate, or successor to the extent reasonable.

      SECTION 8.2 INDEMNIFICATION BY BUYER. Notwithstanding any investigation at
any time made by or on behalf of Buyer, Buyer agrees to defend, indemnify and
hold harmless Seller and Shareholder and to the extent applicable, their
officers, directors, employees, agents, successors, heirs and assigns from and

expenses and other costs of any kind or amount whatsoever (including, without
limitation, reasonable attorneys' fees), whether equitable or legal, matured or
contingent, known or unknown, foreseen or unforeseen, ordinary or extraordinary,
patent or latent, which result, either before or after the date of this
Agreement, from any:

            (a) inaccuracy in any representation or warranty made by Buyer in
      this Agreement or pursuant hereto;

            (b) breach of any representation or warranty made by Buyer under
      this Agreement or pursuant hereto;

            (c) failure of Buyer duly to perform and observe any term,
      provision, covenant, agreement or condition under this Agreement or any
      other instrument contemplated by this Agreement; (d) misrepresentation in
      or omission from any of Buyer's Schedules to this Agreement;

            (e) liabilities or obligations related to the operation of the
      Business after the Closing Date, except for all such liabilities or
      obligations arising out of facts and circumstances existing prior to the
      Closing Date; and

            (f) any liability of Buyer imposed upon Seller.

      SECTION 8.3 CLAIMS FOR INDEMNIFICATION. Whenever any claim shall arise for
indemnification hereunder, the party entitled to indemnification (the
"Indemnified Party") shall promptly notify the party obligated to provide
indemnification (the "Indemnifying Party") of the claim and, when known, the
facts constituting the basis for such claim; provided, however, that the failure
to so notify the Indemnifying Party shall not relieve the Indemnifying Party of
its obligation hereunder to the extent such failure does not materially
prejudice the Indemnifying Party. In the event of any claim for indemnification
hereunder resulting from or in connection with any claim or legal proceedings by
a third-party, the notice to the Indemnifying Party shall specify, if known, the
amount or an estimate of the amount of the liability arising therefrom.

      SECTION 8.4 DEFENSE. In connection with any claim giving rise to indemnity
hereunder resulting from or arising out of any claim or legal proceeding by a
person who is not a party to the Agreement, the Indemnifying Party at its sole
cost and expense and with counsel reasonably

                                                                   Page 27 of 34
<PAGE>

satisfactory to the Indemnified Party may, upon written notice to the
Indemnified Party, assume the defense of any such claim or legal proceeding
within thirty (30) days after written notice of the claim is received subject to
a reservation of rights to contest its indemnity obligation and obtain
reimbursement from Indemnified Party for its costs and expenses in defending and
settling same. The Indemnified Party shall be entitled to participate in (but
not control) the defense of any such action, with its counsel and at its own
expense; provided, however, that if there are one or more legal defenses
available to the Indemnified Party that conflict with those available to the
Indemnifying Party, or if the Indemnifying Party fails to take reasonable steps
necessary to diligently defend the claim after receiving notice from the
Indemnified Party that it believes the Indemnifying Party has failed to do so,
the Indemnified Party may assume the defense of such claim; provided, further,
that the Indemnified Party may not settle such claim without the prior written
consent of the Indemnifying Party, which consent may not be unreasonably
withheld. If the Indemnified Party assumes the defense of the claim, the
Indemnifying Party shall reimburse the Indemnified Party for the reasonable fees
and expenses of counsels retained by the Indemnified Party and the Indemnifying
Party shall be entitled to participate in (but not control) the defense of such
claim, with its counsel and at its own expense. If the Indemnifying Party
thereafter seeks to question the manner in which the Indemnified Party defended
such third-party claim or the amount or nature of any such settlement, the
Indemnifying Party shall have the burden to prove by a preponderance of the
evidence that the Indemnified Party did not defend or settle such third-party
claim in a reasonably prudent manner. The parties agree to render, without
compensation but with reimbursement for out-of-pocket costs, to each other such
assistance as they may reasonably require of each other in order to insure the
proper and adequate defense of any action, suit or proceeding, whether or not
subject to indemnification hereunder.

      SECTION 8.5 CERTAIN CLAIMS BY SHAREHOLDER. Notwithstanding anything
contained in this Agreement, Shareholder hereby agrees that he will not make any
claim for indemnification against Buyer by reason of the fact that he was a
shareholder, manager, director, officer, shareholder, employee or agent of
Seller, or was serving at the request of Seller as a shareholder, manager,
director, officer, shareholder, employee or agent of another entity, whether
such claim is for judgment, damages, penalties, fines, costs, amounts paid in
settlement, losses, expenses or otherwise or whether such claim is made pursuant
to any statute, charter document, bylaw, agreement or otherwise, with respect to
any action, lawsuit, proceeding, complaint, claim or demand brought by Buyer
against Shareholder pursuant to or arising under this Agreement.

      SECTION 8.6 SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS. This
Agreement, including, but not limited to, all covenants, warranties and
representations contained herein, shall survive the Closing and the Bill of
Sale, and all other documents, instruments or agreements relating to the Assets
and the transactions contemplated herein, and shall not be deemed merged
therein; provided however the warranties, representations and covenants shall
only survive for a period of *** except for warranties, representations and
covenants in respect of post-closing instruction, access to records and the
like, taxes, ERISA liability and environmental matters which shall survive until
the expiration of the applicable statute of limitations.

                                                                   Page 28 of 34
<PAGE>

      SECTION 8.7 LIMITATIONS ON INDEMNIFICATION.

            (a) Any claim for indemnity under this Article 8 with respect to
      representations, warranties and covenants shall be made within ***
      following the end of the applicable survival period and with respect to
      any other matters within *** of the date of Closing.

            (b) Buyer Indemnified Parties shall not make any claim against
      Seller or Shareholder hereunder except to the extent that the aggregate
      amount of Losses for which such claiming parties are otherwise entitled to
      indemnification pursuant to this Article 8 together with losses under the
      Auxiliary Agreement and the Transition Agreement exceeds $*** (the
      "Basket") whereupon the claiming parties shall be entitled to be paid the
      excess of the aggregate amount of all such Losses over the Basket subject
      to the limitations on maximum amount of recovery set forth in Section
      8.7(c).

            (c) The aggregate Losses payable by Seller and Shareholder pursuant
      to this Article 8 with respect to all claims for indemnification together
      with all claims under Article 8 of the Auxiliary Agreement and the
      Transition Agreement shall not exceed $*** (the "Cap"); provided, however,
      that this limitation shall not apply in the event of fraud.

            (d) The gross amount which an Indemnifying Party is liable to, for,
      or on behalf of the Indemnified Party pursuant to this Article (the
      "Indemnifiable Loss") shall be reduced (including, without limitation,
      retroactively) by any insurance proceeds or other amounts actually
      recovered by or on behalf of such Indemnified Party related to the
      Indemnifiable Loss, and shall be further reduced to take account of any
      tax benefit to the Indemnified Party arising from the Indemnifiable Loss.
      If an Indemnified Party shall have received or shall have had paid on its
      behalf an indemnity payment in respect of an Indemnifiable Loss and shall
      subsequently receive directly or indirectly insurance proceeds or tax
      benefits in respect of such Indemnifiable Loss, then such Indemnified
      Party shall pay to such Indemnifying Party the amount of such insurance
      proceeds and tax benefits or, if less, the amount of such indemnity
      payment. For purposes of this Section, tax benefits arising from an
      Indemnifiable Loss shall be determined after taking into account the tax
      detriment, if any, arising from the receipt of insurance proceeds or
      indemnification payments by or on behalf of the Indemnified Party and the
      tax benefit, if any, to the Indemnified Party arising from any payments to
      the Indemnifying Party.

            (e) To the extent there are outstanding obligations under the
      Convertible Note, any obligation of Seller or Shareholder to indemnify
      Buyer shall be first offset against the Convertible Note and any remaining
      sums shall be paid by Seller and shareholder.

      SECTION 8.8 SOLE REMEDY. The provisions of this Article 8 shall be the
sole remedy available to a person for a breach of this Agreement.

                                                                   Page 29 of 34

                               ARTICLE 9. GENERAL

      SECTION 9.1 FURTHER ASSURANCES. From time to time after the Closing, each
of Seller and Shareholder will, without further consideration, execute and
deliver such other instruments of conveyance and transfer, and take such other
action as Buyer reasonably may request to more effectively convey and transfer
to and vest in Buyer and to put Buyer in possession of the Assets to be
transferred hereunder. Each of Seller and Shareholder will cooperate and use
their best efforts to have the present officers, directors and employees of
Seller cooperate with Buyer on and after the Closing in furnishing information,
evidence, testimony and other assistance in connection with any actions,
proceedings, arrangements or disputes of any nature with respect to matters
pertaining to all periods prior to the Closing.

      SECTION 9.2 JOINT AND SEVERAL OBLIGATIONS. All representations, warranties
and agreements of Seller and Shareholder under this Agreement, the Schedules and
the transactions contemplated hereby shall be joint and several.

      SECTION 9.3 NO WAIVER. Except as otherwise provided herein, no delay of or
omission in the exercise of any right, power or remedy accruing to any party as
a result of any breach or default by any other party under this Agreement shall
impair any such right, power or remedy, nor shall it be construed as a waiver of
or acquiescence in any such breach or default, or of or in any similar breach or
default occurring later; not shall any waiver of any single breach or default be
deemed a waiver of any other breach of default occurring before or after that
waiver.

      SECTION 9.14 [Intentionally Deleted]

      SECTION 9.15 [Intentionally Deleted]

      SECTION 9.16 ALLOCATION OF CERTAIN EXPENSES.

            (a) All Allocable Expenses (as defined below) shall be prorated
      between pre-Closing and post-Closing periods, and between the Seller and
      the Buyer, based on the number of days elapsed, unless it is otherwise
      evident on the face of an invoice or bill that a particular item, service
      or expense is specifically attributable to a period before or after the
      Closing. Allocation and settlement of all Allocable Expenses paid by the
      parties shall be made within sixty (60) days following the Closing Date.

            (b) "Allocable Expenses" means and includes operating expenses of
      the Business benefiting or attributable to a period beginning before and
      ending after the Closing Date. Examples of Allocable Expenses include
      items such as rent, electricity, water, gas and telephone service,
      advertising, equipment rental, maintenance expenses, and the like.
      "Allocable Expenses" shall not include payroll expense, insurance expense,
      interest expense or any other expense attributable solely to the operation
      of the Assets or the conduct of the Business by the Seller, nor any
      property taxes or assessments prorated at Closing.

                                                                   Page 32 of 34

      SECTION 9.17 MEDIATION/ARBITRATION.

            (a) In the event of any dispute under this Agreement, the parties
      hereto desire to avoid litigation. Accordingly, the aggrieved party will
      give notice of the dispute to the other party and both parties will
      attempt to settle the dispute during the thirty (30) day period following
      such notice. If such dispute remains unsettled, the parties agree to then
      submit such dispute to mediation. If the parties cannot agree on a
      mediator, each will select a mediator and the two chosen mediators will
      select a third mediator who shall alone hear the dispute. Such mediation
      will, if possible, be conducted during the sixty (60) day period following
      expiration of the thirty (30) day period. The costs of mediation
      (including the mediator's fees and expenses and costs directly related to
      the conduct of the mediation, but excluding each party's direct costs for
      transportation, attorneys, etc., for which each will be responsible) will
      be shared equally by the parties. If such mediation fails to resolve the
      dispute, the parties agree such dispute will be submitted to final and
      binding arbitration in accordance with the rules of JAMS/ENDispute by a
      panel of three (3) arbitrators; provided if the claim is $100,000 or less,
      the arbitration panel shall consist of one (1) arbitrator. Unless
      otherwise directed by the arbitration panel, such arbitration must be
      concluded within ninety (90) days of the expiration of the sixty (60) day
      period previously specified for mediation. Any mediation or arbitration
      conducted hereunder will be conducted in Greenville, South Carolina.

            (b) If any party hereto resorts to arbitration to remedy a breach of
      this Agreement, the prevailing party in the arbitration, in addition to
      any other remedies available under this Agreement or by law, may collect
      all or a portion of its reasonable attorney fees and other costs and
      expenses of arbitration, including fees, expenses and compensation paid to
      JAMS and the arbitrators at the discretion of the arbitration panel, who
      shall consider both the reasonableness of the attorney fees and other
      costs and the relative merits of each party's position. It is the intent
      of all parties hereto to avoid arbitration without preventing a party from
      seeking redress for a valid dispute. To that end, all parties express
      their intent and agreement that unreasonable attorney fees and costs not
      be awarded, and that all or a portion of reasonable attorney fees and
      costs be awarded when in the arbitration panel's opinion is the prevailing
      party. Further, it is all parties intent that any party seeking redress
      through litigation despite the fact that arbitration is required by this
      Agreement, shall not be entitled to recover any attorney fees or costs for
      such litigation or in any subsequent arbitration, regardless of the
      outcome of such litigation or subsequent arbitration.

            (c) Notwithstanding anything contained herein to the contrary, Buyer
      shall be entitled to pursue all legal and equitable remedies available to
      it without regard to this Section 9.17 for any violation or threatened
      violation of Section 5.2 hereof.

      SECTION 9.18 GOVERNING LAW. This Agreement shall in all respects be
governed by and construed in accordance with the internal laws of the State of
South Carolina.

      SECTION 9.20 CONTRACT INTERPRETATION; CONSTRUCTION OF AGREEMENT.

            (a) The headings contained in this Agreement are for reference

      interpretation of this Agreement. Article, Section, Exhibit, Schedule,
      preamble, Premises and party references are to this Agreement unless
      otherwise stated.

            (b) Each party hereto acknowledges that each party was actively
      involved in the negotiation and drafting of this Agreement and, therefore,
      no party, nor its respective counsel, shall be deemed the drafter of this
      Agreement for purposes of construing the provisions of this Agreement, and
      all language in all parts of this Agreement shall be construed in
      accordance with its fair meaning, and not strictly for or against any
      party.

payments on preclosing invoices will be directed to be paid to Seller's post
office box and post closing invoices of Buyer will direct payment to be paid to

                    ARTICLE 4. REPRESENTATIONS AND WARRANTIES
                            OF SELLER AND SHAREHOLDER

      SECTION 4.1 Seller and Shareholder, jointly and severally, represent and
warrant to Buyer that:

            (a)   AUTHORITY.

                  (i)   Seller is a duly organized and validly existing South
            Carolina corporation, duly qualified or authorized to do business in
            the State of South Carolina and in each jurisdiction in which such
            qualification or authorization is required except where failure to
            be so qualified or licensed would not have a material adverse effect
            on the Assets or the Business. The execution and delivery of this
            Agreement, the consummation of the transactions contemplated hereby
            and the compliance by Seller and Shareholder with the terms of this
            Agreement do not and will not conflict with or result in a breach of
            any terms of, or constitute a

                                                                    Page 9 of 33

<PAGE>

            default under, the Articles of Incorporation or Bylaws of Seller, or
            any instrument or other agreement to which Seller or Shareholder is
            a party or by which Seller or Shareholder, or any of their
            respective properties or assets, is bound. This Agreement
            constitutes a valid obligation of Seller and Shareholder enforceable
            against Seller and Shareholder in accordance with its terms except
            as may be limited by applicable bankruptcy, insolvency, moratorium
            or similar laws of general application relating to or affecting
            creditor's rights generally and except for the limitations imposed
            by general principles of equity.

                  (ii)  Shareholder is competent, under no duress or legal
            restraint, and has all necessary authority to enter into this
            Agreement, perform Shareholder's obligations hereunder and
            consummate the transactions contemplated hereby.

                  (iii) Seller has the full power and authority to enter into
            this Agreement and to consummate the transactions contemplated
            hereby. Seller has taken all action necessary to approve the sale of
            the Assets to Buyer, including Shareholder approvals, if necessary,
            and except as otherwise set forth herein, no other authorization or
            approval is required for any of the foregoing.

                  (iv)  All of the issued and outstanding shares of capital
            stock of Seller are owned of record and beneficially by the
            Shareholder, free and clear of all liens, security interests and
            encumbrances whatsoever.

                  (v)   Seller does not have any subsidiaries or any other
            equity interest in any limited liability company, corporation,
            partnership or similar entity.

            (b)   COMPLIANCE WITH LAW. To Seller's knowledge, neither Seller nor
      any Shareholder is in default under any applicable federal, state or local
      laws, statutes, ordinances, permits, licenses, orders, approvals,
      variances, rules or regulations or judicial or administrative decisions
      ("Applicable Laws") which would have a material adverse effect upon the
      Assets or the Business. Seller has been granted all material licenses,
      permits, consents, authorizations and approvals from federal, state and
      local government regulatory bodies necessary or desirable to carry on the
      Business, all of which are currently in full force and effect. To Seller's
      knowledge, the operation, conduct and ownership of the properties, assets
      and Business of Seller are being, and at all times have been, conducted in
      compliance with all Applicable Laws in all material respects. No notice
      from any governmental body has been served upon or given to Seller
      claiming that the Business or any of the Assets is not in conformity with
      any Applicable Law.

            (c)   EQUIPMENT. Listed on Schedule 1.1(a) hereto is a complete and
      accurate list of all Equipment used or for use in connection with the
      Business. In the aggregate, the Equipment including the Rolling Stock is
      sufficient to conduct the business as historically conducted.

            (d)   ROLLING STOCK. Listed on Schedule 1.1(b) hereto is a complete
      and accurate list of all Rolling Stock.

            (e)   CONTRACTS AND LEASES. Listed on Schedule 4.1(e) hereto is a
      complete and accurate list of all of the Contracts as of the date hereof
      (i) with all Customers from

                                                                   Page 10 of 33

<PAGE>

      which five percent (5%) or more of the Business' average monthly revenue
      is derived, or (ii) other than customer agreements entered into in the
      ordinary course of business by which the Seller is or the Assets are
      bound. Also listed on Schedule 4.1(e) hereto is a complete and accurate
      list of all of the leases as of the date hereof which will be assumed by
      Buyer (the "Assumed Leases"). Except to the extent consent to assignment
      may be required as indicted in Section 1.3 and except as set forth on
      Schedule 4.1(e), all Contracts and Assumed Leases are (and unless
      terminated by a party in accordance with its terms will be immediately
      following the Closing) in full force and effect and are valid, binding and
      enforceable against the respective parties thereto in accordance with
      their respective provisions. Seller is not in material default under any
      of the Contracts or Assumed Leases; nor has there occurred an event or
      condition (including Seller's execution and delivery of or performance
      under this Agreement) which with the passage of time or the giving of
      notice (or both) would constitute a material default under any obligation
      under any of the Contracts or Assumed Leases; no claim of such a default
      has been asserted and there is no reasonable basis upon which such a claim
      could validly be made. To the best of the Seller's and Shareholder's
      knowledge, no person intends or desires to modify, waive, amend, rescind,
      release, cancel or terminate any of the Contracts or Assumed Leases;
      provided the foregoing shall not be construed to apply to any termination
      of a temporary rollout which although the arrangement may be subject to a
      written trip ticket which contains contractual provisions does not have a
      specified term and by its nature is a temporary arrangement which may end
      at any time. Notwithstanding the foregoing, nothing in this Section 4.1(e)
      or otherwise in this Agreement shall be construed as a guaranty or
      warranty that any of the customers of the Business, including without
      limitation those operating under oral arrangements will continue to
      purchase services after the Closing.

            (f)   TITLE TO THE ASSETS. Except for liens securing the obligations
      described in Section 7.2(d), Seller has good and marketable title to all
      of the Assets, and at Closing all such Assets will be free and clear of
      all liens, encumbrances, security interests, equities or restrictions
      whatsoever, direct or indirect, accrued, absolute, contingent or otherwise
      and, by virtue of the grant, conveyance, sale, transfer, and assignment of
      the Assets hereunder. Except for liens securing the obligations described
      in Section 7.2(d), Buyer shall receive good and marketable title to the
      Assets, free and clear of all liens, lease payments (including lease-end
      buy-out payments), encumbrances, security interests, equities or
      restrictions whatsoever other than liens for taxes not yet due and
      payable.

            (g)   TITLE TO OPERATIONS PROPERTY. Seller currently operates the
      Business on the real property listed on Schedule 4.1(g). (the "Operations
      Property"). Except as set forth on Schedule 4.1(g), Seller has never
      owned, leased or otherwise occupied, had an interest in or operated any
      real property other than the Operations Property. Except as set forth on
      Schedule 4.1(g).

                  (i)   The Operations Property is, and at all times during
            operation of the Business has been, fully licensed, permitted and
            authorized for the operation of the Business under all Applicable
            Laws relating to the protection of the environment, the Operations
            Property and the conduct of the Business thereon (including, without
            limitation, all zoning restrictions and land use requirements)

                                                                   Page 11 of 33

<PAGE>

            except where the failure to be so licensed, permitted or authorized
            would not have a material adverse effect on the Business or Assets.

                  (ii)  Neither Seller, Shareholder nor the Operations Property
            (with respect to activities of Seller) now is or ever has been
            involved in any litigation or administrative proceeding seeking to
            impose fines, penalties or other liabilities or seeking injunctive
            relief for violation of any Applicable Laws relating to the
            environment.

                  (iii) There have been no material spills, leaks, deposits or
            other releases of Hazardous Materials into or onto the Operations
            Property by Seller.

                  (iv)  Except as set forth on Schedule 4.1(g) or except as
            permitted by law, the Operations Property does not contain any
            underground or above-ground storage tanks or transformers containing
            Hazardous Materials, petroleum products or wastes or other hazardous
            substances regulated by 40 CFR 280 or other Applicable Laws which
            were placed on the Operations Property by Seller or to its knowledge
            by any third party. All above and below ground tanks currently in
            use on the Operations Property are being used and maintained in
            accordance with all Applicable Laws.

            (h)   LITIGATION. Except as set forth on Schedule 4.1(h) hereof,
      Seller has no knowledge of any claim (including Notices of Violation),
      litigation, action, suit or proceeding, administrative or judicial,
      pending or threatened against Seller or Shareholder, or involving the
      Assets or the Business, at law or in equity, before any federal, state or
      local court or regulatory agency, or other governmental authority. Neither
      Seller nor Shareholder has any knowledge of any of the above, and neither
      Seller nor Shareholder has any knowledge of any facts or circumstances
      that exist which would, with the passage of time or giving of notice (or
      both), give rise to any of the above.

            (i)   EMPLOYEES. Attached as Schedule 4.1(i) hereof is a complete
      list of all employees of the Business and their respective rates of
      compensation (including a breakdown of the portion thereof attributable to
      salary, bonus and other compensation, respectively) as of the date of
      Closing. Each employee is an employee at will and there are no other
      collective bargaining agreements affecting any employee of Seller. There
      is no pending or, to the best of Seller's and Shareholder's knowledge,
      threatened labor dispute involving Seller and any group of its employees
      nor has Seller experienced any labor interruptions over the past three
      years. Shareholder will cause Seller to terminate each of its employees as
      of the close of business on the Closing Date. Buyer agrees to employ such
      former employees of Seller as Buyer deems appropriate, provided that each
      such person seeking employment meets the qualifications established by

      on a national securities exchange or traded on the NASDAQ National Market
      System and with which such persons have no other connection whatsoever.

            (b)   For a period of *** after the Closing Date, neither Seller nor
      Shareholder shall, offer to employ any person who is, at that time, or who
      has been known by

                                                                   Page 19 of 33

<PAGE>

      Shareholder to have been within one (1) year prior to that time, an
      employee of the Business.

            (c)   For a period of *** after the Closing Date, neither Seller nor
      Shareholder shall, engage or participate in any effort or act to solicit
      or induce any customer, supplier, associate, employee, sales or other
      agent, independent contractor or other person that has a business
      relationship with the Business, within the Territory, or which has been a
      customer, supplier, employee, sales or other agent, independent
      contractor, or other person in a business relationship with the Business,
      Buyer or any of Buyer's Affiliates within the Territory within *** prior
      to that time, to discontinue such relationship with the Business.

            (d)   Seller and Shareholder acknowledge that the damages that would
      be suffered by Buyer as a result of any breach of the provisions of this
      Section 5.2 may not be calculable and that an award of a monetary judgment
      for such a breach would be an inadequate remedy. Consequently, Buyer shall
      have the right, in addition to any other rights it may have, to obtain, in
      any court of competent jurisdiction, injunctive relief to restrain any
      breach or threatened breach of any provision of this Section 5.2 or
      otherwise to specifically enforce any of the provisions hereof, and Buyer
      shall not be obligated to post a bond or other security in seeking such
      relief. This remedy is in addition to damages directly or indirectly
      suffered by Buyer or its Affiliate and if the court or other tribunal
      determines that the breach or threatened breach was material and it is
      otherwise equitable, reasonable attorneys fees.

            (e)   Each of Seller and Shareholder hereby acknowledges and agrees
      that a part of the consideration for the agreements contained in this
      Section 5.2 is the aggregate of the direct and indirect benefits that each
      of Seller and Shareholder are receiving under this Agreement and the
      Auxiliary Agreement, including but not limited to the Purchase Price paid
      by Buyer. Each of Seller and Shareholder further acknowledges and agrees
      that this Agreement contains reasonable limitations as to the time,
      geographical area, and scope of activity to be restrained, and does not
      impose a greater restraint than is necessary to protect the goodwill and
      other legitimate business interests of Buyer, the value of the Assets and
      the Business acquired by Buyer. Therefore, each of Seller and Shareholder
      agrees that all restrictions are fairly compensated for and that no
      unreasonable restrictions exist. In the event that any court of competent
      jurisdiction finally determines that the time period, scope or the
      geographic area of any covenant contained in this Section 5.2 is
      unreasonable or excessive and any such covenant is to that extent made
      unenforceable, the parties agree that the restrictions contained in this
      Section 5.2 shall remain in full force and effect for the greatest time
      period and scope and within the greatest geographic area as is permissible
      without rendering such covenant unenforceable. The parties intend that
      each of the covenants contained in Sections 5.2(a), (b), (c) and (d) shall
      be deemed to constitute separate covenants. The parties further agree that
      the consideration paid to the Seller hereunder is paid for the benefit of
      Shareholder, that Shareholder will derive substantial benefits therefrom
      and, therefore, the covenants contained in this Section 5.2 are binding
      upon Shareholder.

            (f)   All of the covenants contained in this Section 5.2 shall be
      construed as an agreement independent of any other provision of this
      Agreement, and the existence of

                                                                   Page 20 of 33

<PAGE>

      any claim or cause of action of either Seller or Shareholder against
      Buyer, whether predicated on this Agreement or otherwise, shall not
      constitute a defense to the enforcement by Buyer of such covenants.

            (g)   Each of Seller and Shareholder agrees that the covenants
      contained in this Section 5.2 are a material and substantial part of this
      transaction.

            (h)   Because of the difficulty of measuring economic losses as a
      result of the breach of the foregoing covenants, and because of the
      immediate and irreparable damage that would be caused for which it would
      have no other adequate remedy, Buyer and each of Seller and Shareholder
      agrees that, in the event of a breach by either of Seller or Shareholder
      of any of the covenants contained in this Article 5, such covenant or
      covenants may be enforced against each of Seller and each Shareholder by
      injunctions and restraining orders.

            (i)   Notwithstanding the above, in the event there is a default
      under the Convertible Note, and such default continues for ten (10)
      business days after written notice thereof, the provision of this Section
      5.2 shall terminate for all time.

      SECTION 5.3 AUDIT ASSISTANCE. Buyer, at its own cost and expense, may
engage external auditors to audit Seller's financial records relating to the
Business (including up to three years of historical data). Seller agrees to take
all commercially reasonable efforts (at Buyer's cost) to cooperate with any such
audit and to assist in the completion of such audit, including, without
limitation, by providing, executing and acknowledging all such documents that
are necessary to complete the audit (including having Seller's financial records
converted, for Buyer's use only, to accrual based accounting financials in
accordance with GAAP), and by making any representations regarding the Business
and Seller's financial records, as may be reasonably requested by Buyer or the
external auditors and which Seller reasonably believes are accurate.

      SECTION 5.4 SURVIVAL. Each of the covenants set forth in Sections 5.1 and
5.3 shall survive the Closing, the transfer of the Assets, the Bill of Sale and
all other documents, instruments or agreements relating to the transactions
contemplated herein as set forth in Section 8.7. Each of the covenants set forth
in Section 5.2 shall survive the Closing, the transfer of the Assets, the Bill
of Sale and all other documents, instruments or agreements relating to the
transactions contemplated herein as set forth in Section 5.2.

               ARTICLE 6. REPRESENTATIONS AND WARRANTIES OF BUYER

      SECTION 6.1 Buyer represents and warrants to the Seller that:

            (a)   Due Organization. Buyer is a duly organized and validly
      existing Delaware limited liability company, duly qualified or authorized
      to carry on its business in the places and in the manner as now conducted
      except for where the failure to be so authorized, qualified or licensed
      would not have a material adverse affect on its business.

            (b)   Execution. Subject to receipt of the approval of WCA's and
      Buyer's Board of Directors, (i) the execution, delivery and performance of
      this Agreement and the

                                                                   Page 21 of 33

      transactions contemplated hereby are duly and validly authorized by all
      requisite corporate action on the part of Buyer and WCA, and (ii) this
      Agreement constitutes the legal, valid and binding obligation of Buyer and
      WCA enforceable in accordance with its terms, except as may be limited by
      applicable bankruptcy, insolvency, moratorium or similar laws of general
      application relating to or affecting creditor's rights generally and
      except for the limitations imposed by general principles of equity.

            (c)   Conformity with Law. Buyer and WCA have the power and right to
      enter into and perform this Agreement and the transactions contemplated
      herein. Neither Buyer's nor WCA's execution of this Agreement nor the
      consummation of the transactions contemplated herein violate or conflict
      with (i) any law, rule, regulation, ordinance or decree applicable to
      Buyer or WCA; (ii) any provision of Buyer's Certificate of Organization or
      Limited Liability Company Agreement; (iii) any provision of WCA's
      Certificate of Incorporation or By-Laws; or (iv) any material agreement or
      instrument to which Buyer or WCA is a party or by which it is bound.

            (d)   Due Diligence.

            (i)   Buyer has knowledge and experience in financial and business
      matters and is capable of evaluating the merits and risks of the
      transaction contemplated by this Agreement. Buyer confirms that
      Shareholder has provided to the Buyer the opportunity to ask questions of
      the management of the Seller and to acquire such additional information
      about Seller and financial condition of Seller as the Buyer requested, and
      to Buyer's knowledge, all such information has been received. Buyer
      further acknowledges that neither Seller nor any Shareholder, director,
      officer, employee, or agent has made any warranty, express or implied, as
      to the future profitability of the Business for Buyer, or with respect to
      any forecasts, projections, or business plans prepared by or on behalf of
      Seller or Shareholder and delivered to Buyer in connection with the
      Business and the negotiation and the execution of this Agreement.

            (ii)  Buyer is not aware of any inaccuracies of representations and
      warranties of Seller under this Agreement. To the extent that Buyer has
      become aware of any such inaccuracies prior to Closing (through its due
      diligence or otherwise), Seller shall have no obligation to indemnify
      Buyer under this Agreement.

      SECTION 6.2 SURVIVAL. Each of the representations and warranties set forth
in this Article 6 shall survive the Closing and the transfer of the Assets.

                    ARTICLE 7. NON-ASSUMPTION OF LIABILITIES

      SECTION 7.1 NON-ASSUMPTION OF LIABILITIES. Buyer does not assume and shall
not be responsible for any liabilities, indebtedness or obligations of the
Selling Parties or the Business other than the Assumed Obligations (as defined
herein). Without limiting the generality of the foregoing sentence, the Parties
hereby agree that except as expressly set forth in Section 7.2 hereof, Buyer

contingent, known or unknown, foreseen

                                                                   Page 22 of 33

circumstance (whether known or unknown) which occurs or exists on or prior to

injury to or death of any person or damage to or destruction of any property,
whether based on negligence, breach of warranty, or any other theory; (c) a

1998, as amended by that certain First Amendment to Disposal Agreement dated
June 29, 2000 ((a) through (r) being referred to collectively as the "Retained
Liabilities"). The Seller shall retain all of the Retained Liabilities. The
assumption of the Assumed Liabilities by Buyer hereunder shall not in any
respect enlarge any rights of third parties under contracts or arrangements with
Buyer

                                                                   Page 23 of 33

faith any of the Assumed Liabilities with any third party. Seller agrees to
indemnify Buyer and its successors and assigns from and against any liabilities
or obligations related to any Retained Liabilities in accordance with Section
8.1 hereof.

      SECTION 7.2 ASSUMPTION OF SPECIFIC LIABILITIES. At the Closing, Buyer

reasonable attorneys' and accountants' fees and other expenses), whether

      Seller or Shareholder in this Agreement or pursuant hereto;

            (b)   breach of any representation or warranty under this Agreement
      by any of Seller or Shareholder in this Agreement or pursuant hereto;

      any term, provision, covenant, agreement or condition under this Agreement
      or any other instrument contemplated by this Agreement, including, without
      limitation, the covenants and agreements contained in Section 5.2 hereof;

                                                                   Page 24 of 33

            (e)   any material misrepresentation in, or omission from, any
      Schedule to this Agreement;

            (f)   any liability of any of Seller or Shareholder imposed upon
      Buyer as a result of any of Seller or Shareholder's failure to qualify for
      an exemption from, and obtain the protection afforded by compliance with,
      the notification requirements of, the bulk transfer or sales laws in force
      in such jurisdictions in which such laws may be applicable to any of
      Seller or Shareholder or the transactions contemplated under this
      Agreement;

            (g)   any liability of any of Seller or Shareholder resulting from
      one or more pending or threatened lawsuits, whether or not listed on
      Schedule 4.1(h);

            (h)   any liability to, or asserted by, any employee or former

      their employment with Seller or from any of Seller or Shareholder's
      alleged conduct prior to the Closing Date;

            (i)   any liability of any of Seller or Shareholder to creditors of
      any of Seller or Shareholder which liability is imposed on Buyer whether
      as a result of bankruptcy proceedings or otherwise and whether as an

or incurred by Buyer, or any parent, subsidiary, affiliate, or successor of
Buyer, as applicable. The amount of the loss, claim, action, cause of action,
damage, liability, expense or other cost deemed to be suffered, paid or incurred
by Buyer shall be an amount equal to the loss, claim, action, cause of action,
damage, liability, expense or other cost suffered, paid or incurred by such
parent, subsidiary, affiliate, or successor to the extent reasonable.

                                                                   Page 25 of 33

<PAGE>

      SECTION 8.2 INDEMNIFICATION BY BUYER. Notwithstanding any investigation at
any time made by or on behalf of Buyer, Buyer agrees to defend, indemnify and
hold harmless Seller and Shareholder and to the extent applicable, their
officers, directors, employees, agents, successors, heirs and assigns from and
against all losses, claims, actions, causes of action, damages, liabilities,
expenses and other costs of any kind or amount whatsoever (including, without
limitation, reasonable attorneys' fees), whether equitable or legal, matured or
contingent, known or unknown, foreseen or unforeseen, ordinary or extraordinary,
patent or latent, which result, either before or after the date of this
Agreement, from any:

            (a)   inaccuracy in any representation or warranty made by Buyer in
      this Agreement or pursuant hereto;

            (b)   breach of any representation or warranty made by Buyer under
      this Agreement or pursuant hereto;

            (c)   failure of Buyer duly to perform and observe any term,
      provision, covenant, agreement or condition under this Agreement or any
      other instrument contemplated by this Agreement;

            (d)   misrepresentation in or omission from any of Buyer's Schedules
      to this Agreement;

            (e)   liabilities or obligations related to the operation of the
      Business after the Closing Date, except for all such liabilities or
      obligations arising out of facts and circumstances existing prior to the
      Closing Date; and

            (f)   any liability of Buyer imposed upon Seller.

      SECTION 8.3 CLAIMS FOR INDEMNIFICATION. Whenever any claim shall arise for
indemnification hereunder, the party entitled to indemnification (the
"Indemnified Party") shall promptly notify the party obligated to provide
indemnification (the "Indemnifying Party") of the claim and, when known, the
facts constituting the basis for such claim; provided, however, that the failure
to so notify the Indemnifying Party shall not relieve the Indemnifying Party of
its obligation hereunder to the extent such failure does not materially
prejudice the Indemnifying Party. In the event of any claim for indemnification
hereunder resulting from or in connection with any claim or legal proceedings by
a third-party, the notice to the Indemnifying Party shall specify, if known, the
amount or an estimate of the amount of the liability arising therefrom.

      SECTION 8.4 DEFENSE. In connection with any claim giving rise to indemnity
hereunder resulting from or arising out of any claim or legal proceeding by a
person who is not a party to the Agreement, the Indemnifying Party at its sole
cost and expense and with counsel reasonably satisfactory to the Indemnified
Party may, upon written notice to the Indemnified Party, assume the defense of
any such claim or legal proceeding within thirty (30) days after written notice
of the claim is received subject to a reservation of rights to contest its
indemnity obligation and obtain reimbursement from Indemnified Party for its
costs and expenses in defending and settling same. The Indemnified Party shall
be entitled to participate in (but not control) the defense of any such action,
with its counsel and at its own expense; provided, however, that if there are
one or more legal defenses available to the Indemnified Party that conflict with
those available to the Indemnifying Party, or if the Indemnifying Party fails to
take reasonable steps

                                                                   Page 26 of 33

<PAGE>

necessary to diligently defend the claim after receiving notice from the
Indemnified Party that it believes the Indemnifying Party has failed to do so,
the Indemnified Party may assume the defense of such claim; provided, further,
that the Indemnified Party may not settle such claim without the prior written
consent of the Indemnifying Party, which consent may not be unreasonably
withheld. If the Indemnified Party assumes the defense of the claim, the
Indemnifying Party shall reimburse the Indemnified Party for the reasonable fees
and expenses of counsels retained by the Indemnified Party and the Indemnifying
Party shall be entitled to participate in (but not control) the defense of such
claim, with its counsel and at its own expense. If the Indemnifying Party
thereafter seeks to question the manner in which the Indemnified Party defended
such third-party claim or the amount or nature of any such settlement, the
Indemnifying Party shall have the burden to prove by a preponderance of the
evidence that the Indemnified Party did not defend or settle such third-party
claim in a reasonably prudent manner. The parties agree to render, without
compensation but with reimbursement for out-of-pocket costs, to each other such
assistance as they may reasonably require of each other in order to insure the
proper and adequate defense of any action, suit or proceeding, whether or not
subject to indemnification hereunder.

      SECTION 8.5 CERTAIN CLAIMS BY SHAREHOLDER. Notwithstanding anything
contained in this Agreement, Shareholder hereby agrees that he will not make any
claim for indemnification against Buyer by reason of the fact that he was a
shareholder, manager, director, officer, shareholder, employee or agent of
Seller, or was serving at the request of Seller as a shareholder, manager,
director, officer, shareholder, employee or agent of another entity, whether
such claim is for judgment, damages, penalties, fines, costs, amounts paid in
settlement, losses, expenses or otherwise or whether such claim is made pursuant
to any statute, charter document, bylaw, agreement or otherwise, with respect to
any action, lawsuit, proceeding, complaint, claim or demand brought by Buyer
against Shareholder pursuant to or arising under this Agreement.

      SECTION 8.6 SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS. This
Agreement, including, but not limited to, all covenants, warranties and
representations contained herein, shall survive the Closing and the Bill of
Sale, and all other documents, instruments or agreements relating to the Assets
and the transactions contemplated herein, and shall not be deemed merged
therein; provided however the warranties, representations and covenants shall
only survive for a period of *** except for warranties, representations and
covenants in respect of post-closing instruction, access to records and the
like, taxes, ERISA liability and environmental matters which shall survive until
the expirations of the applicable statute of limitations.

      SECTION 8.7. LIMITATIONS ON INDEMNIFICATION.

            (a)   Any claim for indemnity under this Article 8 with respect to
      representations, warranties and covenants shall be made within ***
      following the end of the applicable survival period and with respect to
      any other matters within *** of the date of Closing.

            (b)   Buyer Indemnified Parties shall not make any claim against
      Seller or Shareholder hereunder except to the extent that the aggregate
      amount of Losses for which such claiming parties are otherwise entitled to
      indemnification pursuant to this Article 8 together with Losses under the
      Auxiliary Agreement and the

                                                                   Page 27 of 33

      Transition Agreement exceeds $*** (the "Basket") whereupon the claiming
      parties shall be entitled to be paid the excess of the aggregate amount of
      all such Losses over the Basket subject to the limitations on maximum
      amount of recovery set forth in Section 8.7(b).

            (c)   The aggregate Losses payable by Seller and Shareholder
      pursuant to this Article 8 with respect to all claims for indemnification
      together with all claims under Article 8 of the Auxiliary Agreement and
      the Transition Agreement, shall not exceed $***; provided, however, that
      this limitation shall not apply in the event of fraud.

            (d)   The gross amount which an Indemnifying Party is liable to,
      for, or on behalf of the Indemnified Party pursuant to this Article (the
      "Indemnifiable Loss") shall be reduced (including, without limitation,
      retroactively) by any insurance proceeds or other amounts actually
      recovered by or on behalf of such Indemnified Party related to the
      Indemnifiable Loss, and shall be further reduced to take account of any
      tax benefit to the Indemnified Party arising from the Indemnifiable Loss.
      If an Indemnified Party shall have received or shall have had paid on its
      behalf an indemnity payment in respect of an Indemnifiable Loss and shall
      subsequently receive directly or indirectly insurance proceeds or tax
      benefits in respect of such Indemnifiable Loss, then such Indemnified
      Party shall pay to such Indemnifying Party the amount of such insurance
      proceeds and tax benefits or, if less, the amount of such indemnity
      payment. For purposes of this Section, tax benefits arising from an
      Indemnifiable Loss shall be determined after taking into account the tax
      detriment, if any, arising from the receipt of insurance proceeds or
      indemnification payments by or on behalf of the Indemnified Party and the
      tax benefit, if any, to the Indemnified Party arising from any payments to
      the Indemnifying Party.

            (e)   To the extent there are outstanding obligations under the
      Convertible Note, any obligation of Seller or Shareholder to indemnify
      Buyer shall be first offset against the Convertible Note and any remaining
      sums shall be paid by Seller and shareholder.

      SECTION 8.8. SOLE REMEDY. The provisions of this Article 8 shall be the
sole remedy available to a person for a breach of this Agreement.

                               ARTICLE 9. GENERAL

      SECTION 9.1 FURTHER ASSURANCES. From time to time after the Closing, each
of Seller and Shareholder will, without further consideration, execute and
deliver such other instruments of conveyance and transfer, and take such other
action as Buyer reasonably may request to more effectively convey and transfer
to and vest in Buyer and to put Buyer in possession of the Assets to be
transferred hereunder. Each of Seller and Shareholder will cooperate and use
their best efforts to have the present officers, directors and employees of
Seller cooperate with Buyer on and after the Closing in furnishing information,
evidence, testimony and other assistance in connection with any actions,
proceedings, arrangements or disputes of any nature with respect to matters
pertaining to all periods prior to the Closing.

                                                                   Page 28 of 33

      SECTION 9.2 JOINT AND SEVERAL OBLIGATIONS. All representations, warranties
and agreements of Seller and Shareholder under this Agreement, the Schedules and

      SECTION 9.3 NO WAIVER. Except as otherwise provided herein, no delay of or
omission in the exercise of any right, power or remedy accruing to any party as
a result of any breach or default by any other party under this Agreement shall
impair any such right, power or remedy, nor shall it be construed as a waiver of
or acquiescence in any such breach or default, or of or in any similar breach or
default occurring later; not shall any waiver of any single breach or default be
deemed a waiver of any other breach of default occurring before or after that
waiver.

understanding of the parties with respect to the subject matter hereof, and
supersede all prior and contemporaneous agreements and understandings, oral or
written, relative to said subject matter.

      SECTION 9.7 BINDING EFFECT; ASSIGNMENT. This Agreement and the various
rights and obligations arising hereunder shall inure to the benefit of and be
binding upon the parties hereto and their respective executors, administrators,
heirs, legal representatives, successors and permitted assigns. Neither Seller

hereunder, save and except that Seller and the Shareholder may assign their
rights hereunder to a qualified intermediary for purposes of consummating a
like-kind exchange pursuant to Section 1031 of the Internal Revenue Code of
1986, as amended. Buyer may assign this Agreement without the consent of any of
Seller or any Shareholder; provided, however, that the assignee under such
assignment shall agree to assume the obligations of the assignor under this
Agreement.

      SECTION 9.8 [Intentionally Deleted]

      SECTION 9.9 EXPENSES OF TRANSACTION. Seller and Shareholder shall pay all
costs and expenses incurred by them in connection with this Agreement and the
transactions contemplated hereby and thereby, including, without limitation, the
fees and expenses of the Seller's and Shareholder's attorneys and accountants
and will make all necessary arrangements so that the Assets will not be charged
with or diminished by any such cost or expense. Buyer shall pay all costs and
expenses incurred by it in connection with this Agreement and the transactions
contemplated hereby and thereby, including without limitation, the fees and
expenses of its attorneys and accountants.

      SECTION 9.10 BROKER'S COMMISSION. Seller and Shareholder represents and
warrants to Buyer, and Buyer represents and warrants to each of Seller and
Shareholder, that the warranting party has had no dealings with any third-party
dealer, broker or agent so as to entitle such dealer, broker or agent to a
commission or fee in connection with the sale of the Assets to Buyer hereunder.
If for any reason any commission or fee shall become due, the party dealing with
such dealer, broker or agent shall pay such commission or fee and agrees to
indemnify and save the other party harmless from all claims for such commission
or fee and from all attorneys' fees, litigation costs and other expense relating
to such claim.

      SECTION 9.11 MODIFICATION; REMEDIES CUMULATIVE. This Agreement may not be
changed, amended, terminated, augmented, rescinded or otherwise altered, in
whole or in part, except by a writing executed by all of the parties hereto. No
right, remedy or election given by any term of this Agreement shall be deemed
exclusive but each shall be cumulative with all other rights, remedies and
elections available at law or in equity.

      SECTION 9.12 SEVERABILITY. In case any provision of this Agreement shall
be invalid, illegal or unenforceable, it shall, to the extent possible, be
modified in such manner as to be valid, legal and enforceable but so as to most
nearly retain the intent of the parties. If such modification is not possible,
such provision shall be severed from this Agreement. In either case the
validity, legality and enforceability of the remaining provisions of this
Agreement shall not in any way be affected or impaired thereby.

                                                                   Page 30 of 33

      SECTION 9.13 DUE DILIGENCE INVESTIGATION; KNOWLEDGE. All representations
and warranties contained herein that are made to the knowledge of a party shall
require that such party make reasonable investigation and inquiry with respect
thereto to ascertain the correctness and validity thereof. Without limiting the
foregoing sentence, when any fact is stated to be "to the knowledge of Seller"
or "to the best of Seller's knowledge," such reference shall mean that which
Gary W. Seymore knows or as a business owner should know in the ordinary course
of business. The representations, warranties and covenants of each Selling Party
shall remain operative and in full force and effect regardless of any
investigation made by or on behalf of Buyer, or its respective representatives
unless Buyer obtains actual knowledge to the contrary.

      SECTION 9.14 [Intentionally Deleted]

      SECTION 9.15 [Intentionally Deleted]

      SECTION 9.16 ALLOCATION OF CERTAIN EXPENSES.

            (a)   All Allocable Expenses (as defined below) shall be prorated
      between pre-Closing and post-Closing periods, and between the Seller and
      the Buyer, based on the number of days elapsed, unless it is otherwise
      evident on the face of an invoice or bill that a particular item, service
      or expense is specifically attributable to a period before or after the
      Closing. Allocation and settlement of all Allocable Expenses paid by the
      parties shall be made within sixty (60) days following the Closing Date.

            (b)   "Allocable Expenses" means and includes operating expenses of
      the Business benefiting or attributable to a period beginning before and
      ending after the Closing Date. Examples of Allocable Expenses include
      items such as rent, electricity, water, gas and telephone service,
      advertising, equipment rental, maintenance expenses, and the like.
      "Allocable Expenses" shall not include payroll expense, insurance expense,
      interest expense or any other expense attributable solely to the operation
      of the Assets or the conduct of the Business by the Seller, nor any
      property taxes or assessments prorated at Closing.

      SECTION 9.17 MEDIATION/ARBITRATION.

            (a)   In the event of any dispute under this Agreement, the parties
      hereto desire to avoid litigation. Accordingly, the aggrieved party will
      give notice of the dispute to the other party and both parties will
      attempt to settle the dispute during the thirty (30) day period following
      such notice. If such dispute remains unsettled, the parties agree to then
      submit such dispute to mediation. If the parties cannot agree on a
      mediator, each will select a mediator and the two chosen mediators will
      select a third mediator who shall alone hear the dispute. Such mediation
      will, if possible, be conducted during the sixty (60) day period following
      expiration of the thirty (30) day period. The costs of mediation
      (including the mediator's fees and expenses and costs directly related to
      the conduct of the mediation, but excluding each party's direct costs for
      transportation, attorneys, etc., for which each will be responsible) will
      be shared equally by the parties. If such mediation fails to resolve the
      dispute, the parties agree such dispute will be submitted to

                                                                   Page 31 of 33

<PAGE>

      final and binding arbitration in accordance with the rules of
      JAMS/ENDispute by a panel of three (3) arbitrators; provided if the claim
      is $100,000 or less, the arbitration panel shall consist of one (1)
      arbitrator. Unless otherwise directed by the arbitration panel, such
      arbitration must be concluded within ninety (90) days of the expiration of
      the sixty (60) day period previously specified for mediation. Any
      mediation or arbitration conducted hereunder will be conducted in
      Greenville, South Carolina.

            (b)   If any party hereto resorts to arbitration to remedy a breach
      of this Agreement, the prevailing party in the arbitration, in addition to
      any other remedies available under this Agreement or by law, may collect
      all or a portion of its reasonable attorney fees and other costs and
      expenses of arbitration, including fees, expenses and compensation paid to
      JAMS and the arbitrators at the discretion of the arbitration panel, who
      shall consider both the reasonableness of the attorney fees and other
      costs and the relative merits of each party's position. It is the intent
      of all parties hereto to avoid arbitration without preventing a party from
      seeking redress for a valid dispute. To that end, all parties express
      their intent and agreement that unreasonable attorney fees and costs not
      be awarded, and that all or a portion of reasonable attorney fees and
      costs be awarded when in the arbitration panel's opinion is the prevailing
      party. Further, it is all parties intent that any party seeking redress
      through litigation despite the fact that arbitration is required by this
      Agreement, shall not be entitled to recover any attorney fees or costs for
      such litigation or in any subsequent arbitration, regardless of the
      outcome of such litigation or subsequent arbitration.

            (c)   Notwithstanding anything contained herein to the contrary,
      Buyer shall be entitled to pursue all legal and equitable remedies
      available to it without regard to this Section 9.17 for any violation or
      threatened violation of Section 5.2 hereof.

      SECTION 9.18 GOVERNING LAW. This Agreement shall in all respects be
governed by and construed in accordance with the internal laws of the State of
South Carolina.

      SECTION 9.19 [Intentionally Deleted]

      SECTION 9.20 CONTRACT INTERPRETATION; CONSTRUCTION OF AGREEMENT.

            (a)   The headings contained in this Agreement are for reference
      purposes only and shall not affect in any way the meaning or
      interpretation of this Agreement. Article, Section, Exhibit, Schedule,
      preamble, Premises and party references are to this Agreement unless
      otherwise stated.

            (b)   Each party hereto acknowledges that each party was actively
      involved in the negotiation and drafting of this Agreement and, therefore,
      no party, nor its respective counsel, shall be deemed the drafter of this
      Agreement for purposes of construing the provisions of this Agreement, and
      all language in all parts of this Agreement shall be construed in
      accordance with its fair meaning, and not strictly for or against any
      party.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed
as of the day and year first above written.
