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

          (a)    Tax Returns. The Existing Shareholders will prepare at their
                 -----------                                                 
expense draft schedules of Taxes relating to income of the Companies payable by
the Existing Shareholders for fiscal 1998 and for the period October 1, 1998 to
the Closing Date (as defined) (the "Draft Tax Obligations"). The Existing
Shareholders will deliver such Draft Tax Obligations to HDA as soon as possible
but in any event within 75 days after the Closing.

          (b)    Tax Notice.
                 ---------- 

          (i)    Within 30 days after the receipt of the Draft Tax Obligations,
     HDA will deliver to the Existing Shareholders a written notice certifying
     that either (A) it agrees with the Draft Tax Obligations or (B) it
     disagrees with the Draft Tax Obligations, in which case it will provide
     therewith a reasonably detailed written report stating the basis for
     disagreement with the Draft Tax Obligations (the "Tax Notice"). The
     Existing Shareholders shall provide reasonable access to their respective
     accountants' work papers and personnel and to such historical financial
     information as HDA shall reasonably request in order to review the Draft
     Tax Obligations.

          (ii)   If the Tax Notice is not timely given as described in Section 1
     .2(b)(i), the Draft Tax Obligations furnished by the Existing Shareholders
     to HDA pursuant to Section 1.2(a) shall be final, binding and conclusive
     upon the Parties. If HDA disagrees with such Draft Tax Obligations as
     described in Section 1.2(b)(i)(B), and if the disagreement is not resolved
     by mutual agreement among the Parties within 30 days following delivery of
     the Tax Notice, such dispute will be resolved by a "Big 5" accounting firm
     ("BFAF"), other than PricewaterhouseCoopers LLP, selected by mutual
     agreement of HDA and the Existing Shareholders. The costs of resolving such
     a dispute shall be borne equally by HDA and the Existing Shareholders.

          (iii)  Upon appointment of a BFAF, such BFAF in consultation with the
     Parties shall establish a schedule for resolution of the dispute that is
     reasonably calculated to result in a resolution as expeditiously as
     practicable, and in any event, no later than six months after the Closing
     Date. In resolving such dispute, the BFAF shall revise the Draft Tax
     Obligations only with respect to the issues raised in the Tax Notice. The
     decision of the BFAF shall be final and binding on HDA and the Existing
     Shareholders in the absence of manifest error.

          (c)    Post-Closing Adjustment. Within two business days after a final
                 -----------------------                                        
resolution by the BFAF of such disagreements as may arise out the review of the
Draft Tax Obligations in accordance with Section 1.2(b) above, and an
appropriate adjustment to the Draft Tax Obligations to reflect such resolution,
or if Section 1.2(b)(i)(A) or the first sentence of Section 1.2(b)(ii)
applies, two business days after delivery of, or expiration of the period for
delivering, the Tax Notice (as applicable), the actual cash portion of the
Purchase Price (the "Cash Purchase Price") will be determined based on the
Existing Shareholders' Taxes (as adjusted pursuant to this sentence, if
applicable) instead of the Estimated Existing Shareholders' Taxes, and to the
extent that the Estimated Cash Purchase Price was less than the Cash Purchase
Price, the difference and interest

                                       2

 
thereon due to the Existing Shareholders will promptly be paid to the Existing
Shareholders by HDA. Similarly, to the extent the Estimated Cash Purchase Price
was more than the Cash Purchase Price, the excess and interest thereon will be
promptly returned by the Existing Shareholders to HDA. Any amounts payable
pursuant to this paragraph shall bear interest from the Closing Date through the
date of payment at an annual rate equal to LIBOR as reported in The Wall Street
Journal on the Closing Date.

          3.11 Tax Matters.
               ----------- 

          (a)  For purposes of this Agreement, (i) "Tax" means any federal,
state, local or foreign income, gross receipts, license, payroll, employment,
excise, severance, stamp, occupation, premium, windfall profits, environmental,
customs duties, capital stock, franchise, profits, withholding, social security,
unemployment, disability, real property, personal property, sales, use,
transfer, registration, value added, alternative or add-on minimum, estimated,
or other tax of any kind whatsoever, including any interest, penalty, or
addition thereto, whether disputed or not, and (ii) "Tax Return" means any
return, declaration, report, claim for refund, or information return or
statement relating to Taxes, including any schedule or attachment thereto, and
including any amendment thereof.

          (b)  Each Company has timely filed, or caused to be timely filed, all
Tax Returns that they were required to file. All such Tax Returns were correct
and complete in all respects. All Taxes owed by each Company (whether or not
shown on any Tax Return) have been paid. Neither Company currently is the
beneficiary of any extension of time within which to file any Tax Return. No
claim has ever been made by an authority in a jurisdiction where either Company
does not file Tax Returns that they are or may be subject to taxation by that
jurisdiction. There are no liens on any of the assets of either Company that
arose in connection with any failure (or alleged failure) to pay any Tax.

          (c)  Each Company withheld and paid all Taxes required to have been
withheld and paid in connection with amounts paid or owing to any employee,
independent contractor, creditor, shareholder or other third party.

          (d)  There is no dispute or claim concerning any Tax liability of
either Company either (i) claimed or raised by any authority in writing or (ii)
of which such Company has knowledge. To the knowledge of each Company and each
Existing Shareholder, no audit or examination of any Tax Return is currently in
progress, and neither Company has received notice of any proposed audit or
examination. Each Company has furnished to HDA or its representatives correct
and complete copies of all federal income Tax Returns, examination reports, and
statements of deficiencies assessed against or agreed to by either Company with
respect to the last five fiscal

                                       10

 
years. Neither Company has waived any statute of limitations in respect of Taxes
or agreed to any extension of time with respect to a Tax assessment or
deficiency.

          (e)   Neither Company has filed a consent under Section 341(f) of the
Code concerning collapsible corporations (or any comparable state income tax
provision). Neither Company has made any payments, is obligated to make any
payments, or is a party to any agreement that under certain circumstances could
obligate it to make any payments that will not be deductible under Section 280G
of the Code. Neither Company is a party to any Tax allocation, sharing or
indemnity agreement. Neither Company (i) has been a member of an affiliated
group of corporations filing a consolidated federal income Tax Return or (ii)
has liability for the Taxes of any person under Treasury Regulation Sec. 1.1
502-6 (or any similar provision of state, local or foreign law), as a transferee
or successor, by contract, or otherwise. Schedule 3.11 hereto sets forth all
material elections (e.g., accelerated depreciation, Sec. 263(a) regarding the
allocation of overhead to inventory, and LIFO election for inventory
accounting) in effect as of the date hereof with respect to Taxes affecting
either Company.

          (f)   The unpaid Taxes of each Company did not exceed the reserve for
Tax liability (rather than any reserve for deferred Taxes established to reflect
timing differences between book and Tax income) set forth on the face of such
Company's balance sheet at November 30, 1998. Each Company has made provision,
in conformity with GAAP consistently applied, on their respective compiled
balance sheet disclosed in Section 3.7(b) and (c), and the Companies have made
provisions on the most recent consolidated interim financial statements for the
payment of all Taxes which may subsequently become due.

          (g)   (i) Tisco has been a validly electing S corporation within the
meaning of Sections 1361 and 1362 of the Code at all times since October 1, 1989
and will be an S corporation up to and including the Closing Date.

          (ii)  Redding has been a validly electing S corporation within the
meaning of Sections 1361 and 1362 of the Code at all times during its existence
and will be an S corporation up to and including the Closing Date.

          3.12  Brokers. Finders. Neither Tisco nor Redding has retained any
                ----------------

Returns specified in Section 5.2(f) hereof) and, subject to Section 5.2(g)
hereof, shall timely pay, or cause to be timely paid, when due, all Taxes
relating to such Tax Returns. With respect to Tax Returns of the Companies not

Tisco for any Straddle Period (as hereinafter defined) that is allocated
(pursuant to Section 5.2(j)) to the Pre-Closing Tax Period (such liabilities
collectively, "Pre-Closing Tax Liabilities"); provided, however, that the amount
of the Exiting Tisco Shareholder's indemnity obligation for Taxes pursuant to
this Section 5.2(h) shall be reduced to the extent that the aggregate reserves
for Taxes reflected on Tisco's balance sheet at November 30, 1998 exceeds the
aggregate liability for Taxes for the Pre-Closing Tax Period and not paid prior
to the close thereof.

          (i)  Subject to Section 5.2(c), the Existing Redding Shareholders
shall indemnify, defend, and hold HDA and Redding harmless from and against: any
and all liabilities for Taxes of

Redding Shareholders' indemnity obligation for Taxes pursuant to this Section
5.2(i) shall be reduced to the extent that the aggregate reserves for Taxes
reflected on Redding's balance sheet at November 30, 1998 exceeds the aggregate
liability for Taxes for the Pre-Closing Tax Period and not paid prior to the

          (j) In the case of any taxable period that includes but does not end
on the Closing Date (a "Straddle Period"), Taxes of the Companies for the
Straddle Period shall be allocated to the Pre-Closing Tax Period using an
interim-closing-of-the-books method assuming that such taxable period ended at
the close of the Closing Date, except that (i) exemptions, allowances or
deductions that are calculated on an annual basis (such as the deduction for
depreciation) shall be apportioned on a per-diem basis and (ii) real property,
personal property, intangibles and other similar Taxes shall be allocated in
accordance with the principles of Section 164(d) of the Code.

          (k) Any gains, transfer, sales, use, bulk sales, recording,

law. Such Party shall indemnify, defend, and hold the other Party harmless from
and against any and all liabilities for Conveyance Taxes.

          (1) The Existing Tisco Shareholder with respect to Tisco and the
Existing Redding Shareholders, severally but not jointly with respect to

and against any and all liability for Taxes or other Losses arising out of a
breach or inaccuracy of any representation or warranty contained in Section

in reasonable detail the Existing Shareholders' indemnification obligation.

          (m) HDA shall promptly notify the Existing Shareholders in writing
upon receipt by HDA or any affiliate of HDA of notice of any pending or
threatened proceeding relating to Taxes for which the Existing Shareholders may
be liable under a Tax proceeding ("Tax Proceeding"). The Existing Tisco
Shareholder or the Existing Redding Shareholder, as the case may be, shall have
the sole right to control, conduct, and otherwise represent the interests of
Tisco or Redding in any such Tax Proceeding; provided, however, that without the
                                             --------  -------                  
prior written approval of HDA, which approval shall not be unreasonably withheld
or delayed, no Existing Shareholders shall agree or consent to compromise or
settle any issue or claim arising in any such Tax Proceeding to the extent that
any such compromise, settlement, consent or agreement could have an adverse
effect on HDA for any period ending after the Closing Date.

          (n) Neither HDA nor any affiliate of HDA shall, without the prior
written consent of the Existing Tisco Shareholder or the Existing Redding
Shareholders, as the case may be, which consent shall not be unreasonably
withheld or delayed, file or cause to be filed, any amended Tax Return or claim
for Tax refund with respect to Tisco or Redding relating to Taxes for which any
Existing Shareholder may be liable hereunder. Promptly after the reasonable
request of an Existing Shareholder, at the sole expense of the Existing Tisco
Shareholder or the Existing Redding Shareholder, as the case may be, HDA shall,
or cause Tisco or Redding to, file any amended Tax

                                       34

 
Return or claim for Tax refund relating to Taxes for which any Existing
Shareholder may be liable hereunder, provided that such amended Tax Returns or
                                     --------                                 
claims shall be prepared in a manner consistent with the prior practice of Tisco
or Redding (including elections and accounting methods and conventions) and, in
the reasonable determination of HDA, shall conform to applicable laws and
regulations. If HDA or any affiliate of HDA shall receive a Tax refund relating
to a period or transaction for which any Existing Shareholder is liable
hereunder, HDA shall, within 30 days after receipt of such Tax refund, remit
such Tax refund (including any interest received on such Tax refund and net of
(i) any Tax cost relating to the receipt of such Tax refund and (ii) any
unreimbursed cost or expense incurred in obtaining such Tax refund), to the
Existing Shareholders. For purposes of this Section 5.2 the term "Tax refund"
shall include a reduction in Tax or the use of an overpayment as a credit or
oilier Tax offset, and the receipt of a refund shall be deemed to be realized
upon the earliest to occur of(i) the date on which HDA has actual knowledge that
a payment due to the relevant taxing authority (for which HDA would be
responsible under this Agreement) has been offset by such a refund and (ii) the
receipt of cash.

          (o) After the date hereof, HDA and the Existing Shareholders shall
provide each other with such cooperation and information relating to the
Companies as either party reasonably may request in (i) filing any Tax Return,
amended Tax Return or claim for Tax refund, (ii) determining any Tax liability
or a right to a Tax refund, (iii) conducting or defending any proceeding in
respect of Taxes or (iv) effectuating the terms of this Agreement. The Parties
shall retain all Tax Returns, schedules and work papers, and all material
records and other documents relating thereto, until the expiration of the
statute of limitations (and, to the extent notified by any party, any extensions
thereof) of the taxable years to which such Tax Returns and other documents
relate and until the final determination of any Tax in respect of such years.
Any information obtained under this Section 5.2 shall be kept confidential,
except as may be otherwise necessary in connection with filing any Tax Return,
amended Tax Return, or claim for Tax refund, determining any Tax liability or
right to a Tax refund, or in conducting or defending any proceedings in respect
of Taxes.

          (P) The obligations of the Parties set forth in this Section 5.2 shall
be unconditional and absolute and shall remain in effect until the date that is
90 days after the expiration of the relevant statute of limitations applicable
to the Taxes at issue, giving effect to all valid waivers or extensions thereof
Claims for indemnification arising under or with respect to Section 3.11 or
this Section 5.2 may not be made unless notice of such claims has been given on
or prior to the date that is 90 days after the expiration of the relevant
statute of limitations applicable to the Taxes at issue, giving effect to all
valid waivers or extensions thereof.

          (q) All rights and obligations of the parties hereto with respect to
Taxes, including all rights or either party to indemnification with respect to
Taxes, shall be governed exclusively by the provisions of this Section 5.2 and
3.11, and in particular, the provisions of Article VIII shall not apply to
obligations arising under this Section 5.2.

HDA's Indemnified Persons may suffer, sustain, incur or become subject to
arising out of or due to: (i) any inaccuracy of any representation of any
Existing Tisco Shareholder in this Agreement or in any Schedule hereto; (ii) the
breach of any warranty of any Existing Tisco Shareholder in this Agreement or
any Schedule hereto; (iii) environmental liabilities; (iv) the nonfulfillment of
any covenant, undertaking, agreement or other obligation of any Existing Tisco
Shareholder under this Agreement or any Schedule hereto, not otherwise waived by
HDA; or (v) Tisco's participation in and/or withdrawal from the Commonwealth
Benefit Plan and Associated Trusts or any successor arrangement or trust
(including without limitation any election to withdrawal in the one-time exit
strategy pursuant to the terms of a settlement approved by the court in the
matter of Williams v. Evans & Sons. Inc., Case No. CV95-8360 DT (RMCx) and
          ------------------------------
consolidated cases). "Losses" as used herein is not limited to matters asserted
by third parties, but includes Losses incurred or sustained in the absence of
third party claims. Payment is not a condition precedent to recovery of
indemnification for Losses.

          (b)  Subject to the provisions of this Article VIII, the Existing
Redding Shareholders will jointly and severally indemnify, defend and hold
harmless HDA's Indemnified Persons from and against any and all Losses that
HDA's Indemnified Persons may suffer, sustain, incur or become subject to
arising out of or due to: (i) any inaccuracy of any representation of any
Existing Redding Shareholder in this Agreement or in any Schedule hereto; (ii)
the breach of any warranty of any Existing Redding Shareholder in this Agreement
or any Schedule hereto; (iii) environmental liabilities; or (iv) the
nonfulfillment of any covenant, undertaking, agreement or other obligation of
any Existing Redding Shareholder under this Agreement or any Schedule hereto,
not otherwise waived by HDA. Payment is not a condition precedent to recovery of
indemnification for Losses. In no event, however, shall the liability of Ernie
Linton for indemnification under this Section 8.1(b) exceed the proceeds
received by him from the sale of Redding Shares under this Agreement.

          8.2  Indemnification by Holdings and HDA. Subject to the provisions of
               -----------------------------------                              
this Article VIII, Holdings and HDA agree to indemnified, defend and hold the
Existing Shareholders and their respective heirs, representatives, successors
and assigns (such persons are hereinafter collectively referred to as the
"Existing Shareholders' indemnified Persons"), harmless from and against any
and all Losses that the Existing Shareholders' Indemnified Persons may suffer,
sustain, incur or become subject to arising out of or due to: (a) any inaccuracy
of any representation of Holdings or HDA in this Agreement or in any Schedule
hereto; (b) the breach of any warranty of Holdings or HDA in this Agreement or
any Schedule hereto; and (c) the nonfulfillment of any covenant, undertaking,
agreement or other Obligation of Holdings or HDA under this Agreement or any
Schedule hereto, not otherwise waived by the Existing Shareholders.

                                       38

 
          8.3  Survival of Representations. Warranties and Covenants The several
               -----------------------------------------------------            
representations, warranties, covenants of the Parties contained in this
Agreement or in any document delivered pursuant hereto and the Parties' right to
indemnity in accordance with this Article VIII shall survive the Closing Date
and shall remain in full force and effect for 18 months thereafter whereupon
they will terminate and have no further force or effect; provided, however, that
the representations and warranties set forth in Section 3.11 relating to tax
matters and Section 3.18 relating to employee benefits matters shall survive for
the length of the applicable statute of limitations; provided further that the
                                                     -------- -------
representations and warranties set forth in Sections 3.4, 3.5, 4.4 and 4.7 shall
survive indefinitely.

          8.4  Threshold. No HDA's Indemnified Person or Existing Shareholders'
               ---------
Indemnified Person shall be entitled to any recovery in accordance with this
Article VIII (except with respect to Section 8.1 (a)(v))unless and until the
amount of such Losses suffered, sustained or incurred by such party, or to which
such party becomes subject, by reason of such inaccuracy, breach or
nonfulfillment exceeds $75,000 in the aggregate, whereupon HDA's Indemnified
Persons or the Existing Shareholders' Indemnified Persons, as the case may be,
shall be entitled to indemnification under this Article VIII (subject to the
provisions of Section 8.1(b)) only for the amount of Losses in excess of such
amount up to a maximum amount of $6,500,000.

          8.5  Notice and Opportunity to Defend. If a claim for Losses (a
               --------------------------------                          
"Claim") is to be made by a party seeking indemnification hereunder, such party
seeking indemnification (the "Indemnitee") shall notify the party obligated to
provide indemnification (the "Indemnitor") promptly. If such event involves (a)
any claim or (b) the commencement of any action or proceeding by a third person,
the Indemnitee shall give the Indemnitor written notice of such claim or the
commencement of such action or proceeding. Delay or failure to so notify the
Indemnitor shall only relieve the Indemnitor of its obligations to the extent,
if at all, that it is prejudiced by reasons of such delay or failure. The
Indemnitor shall have a period of 30 days within which to respond thereto. If
the Indemnitor accepts responsibility or does not respond within such 30-day
period, then the Indemnitor shall be obligated to compromise or defend, at its
own expense and by counsel chosen by the Indemnitor, such matter, and the
Indemnitor shall provide the Indemnitee with such assurances as may be
reasonably required by the Indemnitee to assure that the Indemnitor will assume
and be responsible for the entire liability at issue, subject to the limitations
set forth in Sections 8.3 and 8.4 hereof. If the Indemnitor fails to assume the
defense of such matter within said 30-day period, the Indemnitee against which
such matter has been asserted will (upon delivering notice to such effect to the
Indemnitor) have the right to undertake, at the Indemniter's cost and expense,
the defense, compromise or settlement of such matter on behalf of the
Indemnitee. The Indemnitee agrees to cooperate fully with the Indemnitor and
its counsel in the defense against any such asserted liability. In any event,
the Indemnitee shall have the right to participate at its own expense in the
defense of such asserted liability. Any compromise of such asserted liability by
the Indemnitor shall require the prior written consent of the Indemnitee, which
consent will not be unreasonably withheld and in the event the Indemnitee
defends any such asserted liability, then any compromise of such asserted
liability by the Indemnitee shall require the prior written consent of the
Indemnitor, which consent shall not be unreasonably withheld.

          8.6  Indemnification Payments. At the Closing, HDA will deliver by
               ------------------------                                     
wire transfer of immediately available funds $500,000 (Five Hundred Thousand
Dollars) of the Cash Purchase Price to the Escrow Agent to be held by the Escrow
Agent for 18 months pursuant to the terms of the Escrow Agreement and to serve
as partial security for the indemnification obligations of the

                                       39

 
Existing Shareholders under this Agreement. Any indemnification obligations of
the Existing Shareholders under this Article VIII shall be first satisfied by
amounts held by the Escrow Agent pursuant to the terms of the Escrow Agreement.

          8.7  Tax Effect. The calculation of any amounts payable pursuant to
               ---------
Sections 8.1 and 8.2 shall take into account any actual decrease in the
liability of the indemnified party for income taxes arising as a result of
reporting the Loss on any income tax return for the taxable period in which such
Loss is incurred or paid. To the extent such Loss does not result in an actual
decrease in the liability of the indemnified party for income taxes in the
taxable period in which such Loss is incurred or paid but the indemnified party
reasonably believes will result in such a decrease in any of the two subsequent
taxable year following the taxable period in which such Loss was incurred or
paid, the indemnifying party shall promptly transfer to the indemnified party
the entire amount of such decrease at the time such decrease is in fact
realized, whether by paying less income taxes or receiving a refund. If any
decrease in the income tax liability of such indemnified party that is taken
into account in computing the indemnification obligations of an indemnifying
party is subsequently disallowed in a determination (as defined in Section
1313(a) of the Code), the additional income taxes then payable by the
indemnified party as a result of such disallowance shall be a Loss giving rise
to an indemnification payment hereunder. Any payments made pursuant to Sections
8.1 or 8.2 will be treated by HDA and the Existing Shareholders as an adjustment
to the Purchase Price for United States federal income tax purposes.

Agreement may be amended only by written agreement of the Parties hereto, duly
