be, any such excess shall cause a reduction in the principal balance of the
Purchase Note, and (ii) the Purchase Note may be further adjusted by the written
agreement of the parties hereto and making reference to this Section 3.3.  If

payable on the Purchase Note shall be reduced as though such principal amount
were reduced as of January 1, 2001 and all interest paid in excess of what would
have otherwise been required shall reduce the amount of principal payable at the
maturity of the Purchase Note.  If the principal amount of the Purchase Note is
increased, the interest otherwise payable on the Purchase Note shall be
increased as though such principal amount were increased as of January 1, 2001.

amount owing by Seller or Shareholders on the one hand, to either Purchaser or
TKC on the other, as a result of this Agreement and the transactions
contemplated hereby, including without limitation, amounts under Section 11.

          reduction in the principal amount of the Purchase Note (as described
          in Section 3.3). If the difference is a positive amount, the Book
             -----------
          Value Adjustment shall cause an increase in the principal amount of
          the Purchase Note up to a maximum of $200,000 as the maximum

          any disputed items on the Closing Balance Sheet which resolution shall
          be conclusive upon all parties. Said firm shall be required to apply

          addition to the Book Value Adjustment, the Purchase Price shall be
          subject to a right of set-off to the Purchase Note by Purchaser as
          described in Section 3.3 and 11. For purposes of this Agreement,

income tax to the Seller and the Shareholders resulting from the transactions
contemplated hereby and an estimate of the net proceeds after income tax to the
Sellers and the Shareholders if Purchaser had instead purchased all of the
outstanding common stock of Seller. Such difference shall be calculated without
regard to any income tax liability attributable to Internal Revenue Code Section
1374 (built in gains), and shall otherwise be calculated pursuant to the formula
attached as Exhibit 3.5, which formula shall be applied (i) regardless of the
            -----------
actual income tax liability of Seller and the Shareholders as a result of the
transactions contemplated hereby, (ii) without giving effect to any of the
adjustments, if any, to the Purchase Price as provided for in this Agreement,

Adjustment shall be payable by Purchaser pursuant to Section 3.6(c).

     portion of the property or any other assets of Seller is subject to any
     governmental decree or order to be sold or is being condemned, expropriated
     or otherwise taken by any public authority with or without payment of
     compensation therefor, nor to the best of Seller's and Shareholders'
     knowledge has any such condemnation, expropriation or taking been proposed.

     4.13  Insurance.  Set forth in Schedule 4.13 is a complete and accurate
           ---------                -------------
list and description of all policies of fire, liability, errors and omissions,
workers compensation, health and other forms of insurance presently in effect
with respect to the business and properties of Seller, true and correct copies
of which have heretofore been delivered to Purchaser.  Schedule 4.13 includes,
                                                       -------------
without limitation, the carrier, the description of coverage, the limits of
coverage, retention or deductible amounts, amount of annual premiums, date of
expiration and the date through which premiums have been paid with respect to
each such policy, and any claims made within the last five (5) years.  All such
policies are valid, outstanding and enforceable policies and provide insurance
coverage for the properties, assets and operations of Seller, of the kinds, in
the amounts and against the risks customarily maintained by organizations
similarly situated; and no such policy (nor any previous policy) provides for or
is subject to any currently enforceable retroactive rate or premium adjustment,
loss sharing arrangement or other actual or contingent liability arising wholly
or partially out of events arising prior to the date hereof.  Schedule 4.13
                                                              -------------

indicates each policy as to which (a) the coverage limit has been reached or (b)
the total incurred losses to date equal 50% or more of the coverage limit.  No
notice of cancellation or termination has been received with respect to any such
policy, and neither Seller nor any Shareholder has knowledge of any act or
omission of Seller which could result in cancellation of any such policy prior
to its scheduled expiration date.  Seller has not been refused any insurance
with respect to any aspect of the operations of the Business nor has its
coverage been limited by any insurance carrier (other than the initial policy
limit) to which it has applied for insurance or with which it has carried
insurance during the last three (3) years.  Seller has duly and timely made all
claims it has been entitled to make under each policy of insurance.  At all
times during the last three (3) years; (a) all errors and omissions policies
maintained by or for the benefit of Seller have been "claims made" policies and
not "occurrence" policies and (b) all general liability policies maintained by
or for the benefit of Seller have been "occurrence" policies and not "claims
made" policies.  There is no claim by Seller pending under any such policies as
to which coverage has been questioned, denied or disputed by the underwriters of
such policies, and neither Seller nor any of the Shareholders knows of any basis
for denial of any claim under any such policy.  Seller has not received any
written notice from or on behalf of any insurance carrier issuing any such
policy that insurance rates therefor will hereafter be substantially increased
(except to the extent that insurance rates may be increased for all similarly
situated risks) or that there will hereafter be a cancellation or an increase in
a deductible (or an increase in premiums in order to maintain an existing
deductible) or nonrenewal of any such policy.  Such policies are sufficient in
all material respects for compliance by Seller with all requirements of law and
with the requirements of all material contracts to which Seller is a party.

     the foregoing sentence are hereinafter sometimes referred to collectively
     as "Employee Plans/Agreements," and each individually as an "Employee
         -------------------------                                --------
     Plan/Agreement." True and correct copies of all the Employee

     Section 4203 of ERISA) or "partial withdrawal" (as defined in Section 4205
     of ERISA) by any person from any such plan, or otherwise):

               (i)   no such plan has been terminated so as to subject, directly
           or indirectly, any assets of Seller to any liability, contingent or
           otherwise, or the imposition of any lien under Title IV of ERISA;

               (ii)  no proceeding has been initiated or threatened by any

           to terminate any such plan;

               (iii) no condition or event currently exists or currently is
           expected to occur that could subject, directly or indirectly, any
           assets of Seller to any liability, contingent or otherwise, or the

           or to any other person or otherwise on account of the termination of
           any such plan;

               (iv)  if any such plan were to be terminated as of or prior to
           the Closing Date, no assets of Seller would be subject, directly or
           indirectly, to any liability, contingent or otherwise, or the
           imposition of any lien under Title IV of ERISA;

               (v)   no "reportable event" (as defined in Section 4043 of ERISA)
           has occurred with respect to any such plan;

               (vi)  no such plan which is subject to Section 302 of ERISA or
           Section 412 of the Code has incurred any "accumulated funding
           deficiency" (as defined in Section 302 of ERISA and Section 412 of
           the Code, respectively), whether or not waived; and

     any Employee Plan/Agreement, directly or indirectly, could be subject to
     any liability under ERISA, the Code or any other law, regulation or
     governmental order applicable to any Employee Plan/Agreement, or under any
     agreement, instrument, statute, rule of law or regulation pursuant to or
     under which Seller has agreed to indemnify or is required to indemnify any
     person against liability incurred under, or for a violation or failure to
     satisfy the requirements of, any such statute, regulation or order.

               ------------
     Plan/Agreement which is intended to be a funded plan exceed the amounts
     required to be paid, or which would be required to be paid if such Employee
     Plan/Agreement were terminated, on account of rights vested or accrued as
     of the Closing Date (using the actuarial methods and assumptions then used

     such Employee Plan/Agreement required to be filed with any governmental

     to each such Employee Plan/Agreement required to be disclosed or provided
     to participants or their beneficiaries have been timely disclosed or

     compensation or any other payment, except as expressly provided in this

           --------

           (a) Prior to Closing, Seller will take all steps necessary to obtain,

          (b) Seller will use its best efforts prior to Closing to obtain all
     other consents necessary for the consummation of the transactions

                                                            --------------

          (c) All such consents shall be in writing and executed counterparts

     thereof but in no event later than immediately prior to the Closing.

     6.5  Other Action. Seller and the Shareholders shall use their best efforts
          ------------
to cause the fulfillment at the earliest practicable date of all of the
conditions to the obligations of Seller and the Shareholders.

     6.6  Disclosure Schedule. Seller shall have a continuing obligation to
          -------------------
promptly notify Purchaser in writing with respect to any matter hereafter
arising or discovered which, if existing or known at the date of this Agreement,
would have been required to be set forth or described in the Disclosure
Schedule; provided, however, that no such disclosure shall cure any breach of
any representation or warranty which was inaccurate on the date of this
Agreement, and that the acceptance of any one or more of such amendments by
Purchaser shall not affect the condition to the obligation of Purchaser to
consummate the transactions contemplated hereby contained in Section 9.1; any
                                                             -----------
and all adverse changes contained in any such amendments shall be considered in

                                                 -----------

     6.7  Confidentiality.
          ---------------

          (a)  Covenant. Without limiting the extent of any other provisions of
               --------
     this Agreement and except as may be necessary to prepare reports and
     returns to governmental agencies for financial record keeping purposes or
     for other proper business reasons, neither Seller nor any of the
     Shareholders shall subsequent to the Closing (i) retain copies of any
     customer lists, any information regarding customers which is not available
     to the public or any trade secrets or other books, records, contracts and
     documents of Seller among the Purchased Assets, except that Seller may
     retain the information included in this Agreement or in the Disclosure
     Schedule; or (ii) disclose any of the foregoing to any person. Subsequent
     to the Closing, Purchaser shall afford Seller reasonable access to, and
     allow Seller to make copies for a reasonable purpose of, the foregoing
     information for the purposes specified in the preceding sentence during
     normal business hours and upon reasonable notice to Purchaser.

          (b)  Employees. For a period of two years from the Closing Date,
               --------
     neither Seller, none of the Shareholders, nor any Affiliate of either shall
     offer employment to any employee of Seller on the Closing Date or
     subsequent thereto without the prior written consent of Purchaser, except
     that the foregoing restriction shall not apply to any such employee who is
     not hired, or is hired but subsequently terminated, by Purchaser following
     the Closing.

          (c) Equitable Relief for Violations. Seller agrees that the provisions
              -------------------------------
     and restrictions contained in this Section 6.7 are necessary to protect the
                                        -----------
     legitimate continuing

                                     -31-


     interests of Purchaser in acquiring the Business through the purchase of
     the Purchased Assets, and that any violation or breach of these provisions
     will result in irreparable injury to Purchaser for which a remedy at law
     would be inadequate and that, in addition to any relief at law which may be
     available to Purchaser for such violation or breach, Purchaser shall be
     entitled to injunctive and other equitable relief as a court may grant
     after considering the intent of this Section 6.7.
                                          -----------

          (d)  Permitted Disclosure. Notwithstanding the provisions of this
               --------------------
     Section 6.7, disclosure shall be permitted (i) where ordered by a court of
     -----------
     competent jurisdiction or by subpoena, (ii) if required to disclose to an
     employee of Seller in the course of performing work related to that which
     is customarily performed by Seller (provided that such employee enter into
     a written agreement assuring the confidentiality of such information), and
     (iii) where such information is already in the public domain other than
     through a breach by Seller or the Shareholders of this Agreement.

     6.8  Insurance.
          ---------

          (a)  As soon as practicable after the date hereof and prior to the
     Closing, Seller and the Shareholders shall use their best efforts to cause
     the following to occur prior to the Closing with respect to all policies of
     fire, liability, product liability, workers compensation, health and other
     forms of insurance of which Seller is the owner, insured or beneficiary, or
     covering any of the Purchased Assets:

               (i)    upon the reasonable request of Purchaser, cause each
          insurer under any such policy to consent to the transfer of such
          insurance to Purchaser at the Closing as contemplated by this
          Agreement;

               (ii)   deliver to Purchaser evidence reasonably satisfactory to
          Purchaser that Purchaser will not be liable to any insurer under any
          policy that provides for or is subject to any retroactive rate or
          premium adjustment, loss sharing arrangement or other actual or
          contingent liability arising wholly or partially out of events arising
          prior to the Closing for any such rate or premium adjustment, loss
          sharing arrangement or other actual or contingent liability; and

               (iii)  at the reasonable request of Purchaser, cause Purchaser to
          be named as an additional insured under each of its occurrence-type
          policies of insurance insuring against general liability claims,
          claims for personal injury and property damage arising out of or
          resulting from any products sold by Seller prior to the Closing Date
          and workers compensation claims, to the extent an insurer does not
          allow the transfer to Purchaser of any such policies provided,
          however, that in the event the Closing does not occur through no fault
          of Seller, Purchaser shall assume the expense of Purchaser being named
          as an additional insured, until the date Purchaser requests to be
          removed from such policies.

          (b)  Following the Closing, Seller will, to the extent that coverage
     under its insurance policies extends to include Purchaser in accordance
     with the foregoing, (i) take no action to eliminate or reduce such
     coverage, other than normal elimination or

                                     -32-


     reduction of coverage as they occur by virtue of the filing of claims in
     the ordinary course under such insurance policies, (ii) pay when due any
     premiums under such policies for periods through the Closing, including
     retroactive premium adjustments, and (iii) use its best efforts to assist
     in filing and processing claims under, and otherwise cooperate with
     Purchaser to allow it, in its own name, or on behalf of Seller, as the case
     may be, to obtain all coverage benefits under such insurance policies,
     including without limitation the execution of assignments or powers of
     attorney for the benefit of Purchaser. Any proceeds of insurance paid by an
     insurer to Seller for claims of Purchaser made in accordance with this
     Section shall be promptly paid to Purchaser.

          (c)  At the Closing, Seller shall deliver to Purchaser one or more
     certificates of insurance evidencing that the insurance retained or
     obtained by it pursuant to this Section 6.8 is in effect and providing for
                                     -----------
     notification to Purchaser at least ten (10) days prior to the effective
     date of any termination or cancellation of such insurance.

     6.9  Use of Seller's Names. Concurrently with the Closing, Seller shall
          ---------------------
change its corporate name to a new name bearing no resemblance to its present
name so as to permit the use of its present name by Purchaser.  Following the
Closing, neither Seller, nor any Shareholder nor any Affiliate of either shall,
without the prior written consent of Purchaser, make any use, in a commercial
context, of the name "Hook," "Hook & Associates," "Hook & Associates
Engineering," or "Hook Engineering" or any other name confusingly similar
thereto, except as may be necessary for Seller to pay its liabilities, prepare
tax returns and other reports, and to otherwise wind up and conclude its
business.

     6.10 Sales Tax.  Seller will not take any action that would or may
          ---------
reasonably be expected to jeopardize any exemption from sales tax that would
otherwise be available to Purchaser, and Seller will take all actions to allow
Purchaser to avail itself of such exemptions.

     6.11 Employee Matters.
          ----------------

          (a)  "Affected Employees" shall mean employees of Seller who are
                ------------------
     employed by Purchaser immediately after the Closing.

          (b)  Responsibilities.  Seller will satisfy, or cause its insurance
               ----------------
     carriers to satisfy, all claims for benefits, whether insured or otherwise
     (including, but not limited to, workers' compensation, life insurance,
     medical and disability programs), under the Employee Benefit Plans of
     Seller brought by, or in respect of, Affected Employees and other employees
     and former employees of Seller, which claims arise out of events occurring
     on or prior to the Closing Date, in accordance with the terms and
     conditions of such programs or the applicable workers' compensation statute
     without interruption as a result of the employment by Purchaser of any such
     employees after the Closing Date.

          (c)  Termination Benefits. If any action on the part of Seller prior
               --------------------
     to the Closing, or if the sale to Purchaser of the Business pursuant to
     this Agreement or the transactions contemplated hereby, shall result in any
     liability or claim of liability for severance payments or termination
     benefits, or any liability, forfeiture, fine or other obligation by virtue
     of any state, federal or local "plant-closing" or similar law, such

                                     -33-


     liability or claim of liability shall be the sole responsibility of Seller
     and each of the Shareholders, and Seller and each of the Shareholders shall
     indemnify and hold harmless Purchaser for any losses resulting directly or
     indirectly from such liability or claim.

          (d)  No Third-Party Rights.  Nothing in this Agreement, express or
               ---------------------
     implied, is intended to confer upon any of Seller's employees, former
     employees, collective bargaining representatives, job applicants, any
     association or group of such persons or any Affected Employees any rights
     or remedies of any nature or kind whatsoever under or by reason of this
     Agreement, including, without limitation, any rights of employment.

     6.12 Unemployment Compensation.  To the extent allowable under applicable
          -------------------------
law, Seller will, at the request of Purchaser, use its best efforts to assign to
Purchaser unemployment compensation contribution rates and account balances of
Seller.

     6.13 Expenses.  Except as otherwise expressly provided herein, Seller shall
          --------
bear Seller's expenses, the expenses of its counsel and other agents and any
other out-of-pocket expenses in connection with the transactions contemplated
hereby (including without limitation the costs to comply with Section 6.4),
                                                              -----------
and/or Seller shall ensure that such expenses are paid out of the cash
consideration to be delivered to Seller at the Closing.

     (whether one or more, the "Indemnified Party") will give the party from
                                -----------------
     whom indemnification is sought (the "Indemnifying Party") prompt written
                                          ------------------
     notice of any such Claim, and the Indemnifying Party will undertake the
     defense thereof by representatives chosen by it. Failure to give such
     notice shall not affect the Indemnifying Party's duty or obligations under
     this Section 11, except to the extent the Indemnifying Party is prejudiced
          ----------
     thereby. So long as the Indemnifying Party is defending any such Claim
     actively and in good faith, the Indemnified Party shall not settle such
     Claim. The Indemnified Party shall make available to the Indemnifying Party
     or its representatives all records and other materials required by them and
     in the possession or under the control of the Indemnified Party, for the
     use of the Indemnifying Party and its representatives in defending any such
     Claim, and shall in other respects give reasonable cooperation in such
     defense.

           (b) Failure to Defend. If the Indemnifying Party, within a reasonable
               -----------------
     time after notice of any such Claim, fails to defend such Claim actively
     and in good faith, the

                                     -37-


     Indemnified Party (upon further notice) has the right to undertake the
     defense, compromise or settlement of such Claim or consent to the entry of
     a judgment with respect to such Claim, on behalf of and for the account and
     risk of the Indemnifying Party, and the Indemnifying Party shall thereafter
     have no right to challenge the Indemnified Party's defense, compromise,
     settlement or consent to judgment therein.

           (c) Indemnified Party's Rights.  Anything in this Section 11.3 to the
               --------------------------                    ------------
     contrary notwithstanding, (i) if there is a reasonable probability that a
     Claim may materially and adversely affect the Indemnified Party other than
     as a result of money damages or other money payments, the Indemnified Party
     shall have the right to defend, compromise or settle such Claim, and (ii)
     the Indemnifying Party shall not, without the written consent of the
     Indemnified Party, settle or compromise any Claim or consent to the entry
     of any judgment which does not include as an unconditional term thereof the
     giving by the claimant or the plaintiff to the Indemnified Party of a
     release from all liability in respect of such Claim.

     11.4  Payment.  The Indemnifying Party shall promptly pay the Indemnified
           -------
Party any amount due under this Section 11, which payment may be accomplished in

whole or in part, at the option of the Indemnified Party, by the Indemnified
Party setting off any amount owed to the Indemnifying Party by the Indemnified
Party. To the extent set-off is made by an Indemnified Party in satisfaction or
partial satisfaction of an indemnity obligation under this Section 11 that is

disputed by the Indemnifying Party, upon a subsequent determination by final
judgment not subject to appeal that all or a portion of such indemnity
obligation was not owed to the Indemnified Party, the Indemnified Party shall
pay the Indemnifying Party the amount which was set off and not owed together
with interest from the date of set-off until the date of such payment at an
annual rate equal to the annual rate set forth in the Purchase Note.  Upon
judgment, determination, settlement or compromise of any third party Claim, the
Indemnifying Party shall pay promptly on behalf of the Indemnified Party, and/or
to the Indemnified Party in reimbursement of any amount theretofore required to
be paid by it, the amount so determined by judgment, determination, settlement
or compromise and all other Claims of the Indemnified Party with respect
thereto, unless in the case of a judgment an appeal is made from the judgment.
If the Indemnifying Party desires to appeal from an adverse judgment, then the
Indemnifying Party shall post and pay the cost of the security or bond to stay
execution of the judgment pending appeal. Upon the payment in full by the
Indemnifying Party of such amounts, the Indemnifying Party shall succeed to the
rights of such Indemnified Party, to the extent not waived in settlement,
against the third party who made such third party Claim.

           Shareholders hereby waive all applicable statutory limitation periods
           with respect thereto.

               (ii)   Any claim or action brought for breach of any
           representation or warranty made by the Seller or the Shareholders in
           or pursuant to Section 4.5 may be brought at any time until the
                          -----------

           limitation under federal and state laws relating thereto (as such

               (iii)  Any claim or action brought for breach of any
           representation or warranty made by the Seller or the Shareholders in

                          ------------
           underlying claim is barred by the applicable period of limitation
           under federal and state laws relating thereto (as such period may be
           extended by waiver).

               (iv)   Any claim made by a party hereunder by filing a suit or
           action in a court of competent jurisdiction or a court reasonably
           believed to be of competent jurisdiction for breach of a
           representation or warranty prior to the termination of the survival
           period for such claim shall be preserved despite the subsequent
           termination of such survival period.

               (v)  If any act, omission, disclosure or failure to disclosure
           shall form the basis for a claim for breach of more than one
           representation or warranty, and such claims have different periods of
           survival hereunder, the termination of the survival period of one
           claim shall not affect a party's right to make a claim based on the
           breach of representation or warranty still surviving.

     11.6  No Waiver.  The Closing of the transactions contemplated by this
           ---------
Agreement shall not constitute a waiver by any party of its rights to
indemnification hereunder, regardless of whether the party seeking
indemnification has knowledge of the breach, violation or failure of condition
constituting the basis of the Claim at or before the Closing.
