HakeTenn, Inc., a Delaware corporation and an affiliate of the Hake Group of

for $12.9 million in cash and the assumption of $500,000 of indebtedness of
Hake. Hake is a specialist in the storage, transportation handling and

                        GTS DURATEK CLOSES ACQUISITION
                      OF FRANK W. HAKE ASSOCIATES L.L.C.

COLUMBIA, Md., -- GTS Duratek, Inc. (Nasdaq:  DRTK) today announced that it has
closed the acquisition of Frank W. Hake Associates, L.L.C., from an affiliate of
the Hake Group of Philadelphia, Pennsylvania and certain individual
stockholders, for $12.9 million in cash and the assumption of $500,000 of
indebtedness of Hake Associates.  Hake Associates is a specialist in the
storage, transportation handling and processing of radioactive waste emanating
from nuclear power generation plants throughout the United States.  Hake
Associates  also stores and services power generation equipment at their
licensed facility in Memphis, Tennessee.  Hake Associate's revenues for the year
ended December 31, 1998 were approximately $15 million.


Robert E. Prince, GTS Duratek's President and CEO, said, "The purchase of Hake
Associates enhances GTS Duratek's capabilities in the growing market for
radioactive waste processing, specifically for large components resulting from
the decommissioning and dismantling of commercial nuclear power plants.  The
combination of Hake with GTS Duratek's existing services positions the Company
to take advantage of this exciting marketplace opportunity."

Robert F. Shawver, GTS Duratek's Executive Vice President and CFO, added, "This
acquisition has the potential to, on an annual basis, increase commercial
radioactive waste processing revenues in excess of 20% as well as add
significant operational synergies."

GTS Duratek implements technologies and provides services, many of which are
related to managing radiation and treating radioactive waste.  GTS Duratek is
the largest processor of low-level radioactive waste in the U.S. and a leader in
providing decommissioning services.

The Company has included in its periodic filings under the Securities Exchange
Act of 1934, including its Form 10-Q for the quarter ended March 31, 1999,
pursuant to the "safe harbor" provisions contained in the Private Securities
Litigation Reform Act of 1995, certain cautionary statements which are intended
to identify certain important factors that could cause the Company's actual
results to differ materially from those contained in forward-looking statements
of the Company made by or on behalf of the Company.  Reference is made to such
statements for a complete discussion of those factors, which include the ability
to manage the commercial waste processing operations acquired from SEG and
future awards by the DOE and other governmental agencies, public and political
concerns surrounding radioactive waste clean-up efforts, and the timing of
contract awards, extensions, and non-renewals in the technical support services
area.  Also, as stated herein, the timing of contracting efforts, and timing and

                                      ###

success in new contract awards have affected period-to-period comparisons and
are expected to do so in the future.

                                                                           -
Notwithstanding any other provision of this Agreement, Buyer shall not assume
any other long-term debt of Company, HPI or of any of the Sellers.  If the
balance due under the Mortgage note is less than $500,000 on the Closing Date,
Buyer shall pay  Sellers, as additional cash consideration, an amount equal to
the difference between $500,000 and the balance due under the Mortgage note on

     4.3  Additional Consideration.  Buyer shall pay to Sellers an amount of up
          ------------------------
to   Three Hundred Thousand Dollars ($300,000) in cash as Additional
Consideration, under the following terms:

          4.3.1  If, for the period commencing the first day of the month after
the Closing Date, and ending twenty-four (24) months thereafter (the "Twenty-
Four Month Period"), the aggregate net revenues recognized from the
SAFESTORE/SAFESHOP ("SAF") and Inventory Management Services ("IMS") product
lines shall be at least Five Million Dollars ($5,000,000), then Buyer shall pay
to Sellers additional consideration of  One Hundred Thousand Dollars ($100,000).
If the aggregate net revenues recognized from the SAF and IMS product lines
shall be less than Five Million Dollars ($5,000,000) during the Twenty-Four
Month Period, then Buyer shall not pay to Sellers any Additional Consideration
pursuant to this Section 4.3.1.  For purposes of this Agreement, "net revenues"
means gross revenues less discounts, allowances, or credits.

          4.3.2  In addition to the additional consideration described in
Section 4.3.1 above, if, for the Twenty-Four Month Period, the cumulative net
revenues recognized from the SAF and IMS product lines exceed Five Million
Dollars ($5,000,000) in the aggregate (the excess of such net revenues over
$5,000,000 being referred to as "excess revenues"), then Buyer shall pay to
Sellers Additional Consideration of twenty percent (20%) of excess revenues,
subject to a maximum additional consideration under this Section 4.3.2 of Two
Hundred Thousand Dollars ($200,000).

          4.3.3  Within sixty (60) days after the end of the Twenty-Four Month
Period, Buyer shall prepare and deliver to Sellers a schedule setting forth its
calculation of the SAF and IMS net revenues recognized.  The Sellers shall have
the right, at their expense, to have an independent certified public accountant
("CPA") selected by the Sellers and approved by Buyer, such approval not to be
unreasonably withheld provided that the CPA has signed an appropriate
confidentiality agreement, review Buyer's internal work papers or other back-up
detail and substantiation relating to each such calculation.  Buyer will make
its books and records relating solely to the calculation available to such CPA
during reasonable business hours.  The CPA shall agree to advise the Sellers
only of the accuracy or inaccuracy of the Buyer's schedule and, if not accurate,
the actual amounts as computed by such CPA.  Sellers shall notify Buyer of any
differences regarding any such calculation within sixty (60) days following
Sellers' receipt thereof.  Any disagreement as to the computation shall be
settled in accordance with Section 18.11 hereof.  Such calculation shall be
deemed final upon: (i) the expiration of the foregoing

                                      12
<PAGE>

sixty (60) day review period if Sellers have not notified Buyer of any
differences regarding the calculation, or (ii) the resolution of any differences
relating thereto. Buyer shall pay the amounts described in Subsections 4.3.1,
and 4.3.2 above within five (5) days after the applicable schedule becomes
final.

          4.3.4  Buyer acknowledges that timely capital expenditures may be
required and incurred by Buyer in order to meet the target aggregate net
revenues as set forth in Subsections 4.3.1 and 4.3.2 above.  The  projected
capital expenditures are set forth in Schedule 4.3.4.
                                      --------------

          4.3.5   If either line of business (SAF or IMS) is discontinued, or
both of them are discontinued, for any reason, during the Twenty-Four Month
Period, or if any material change in the form, structure, lines or delivery of
services that could materially alter the opportunity to achieve the Additional
Consideration occurs, or if required capital expenditures, as set forth in
Schedule 4.3.4, are not made timely in accordance with the reasonable needs of
- --------------
the Business then the Additional Consideration as described in Subsections 4.3.1
and 4.3.2, above, shall be deemed earned by Sellers and Buyer shall immediately
pay to Sellers such Additional Consideration in the amount of $300,000.
Notwithstanding the foregoing or any other provision in this Agreement to the
contrary, if either the SAF or the IMS business incurs cumulative operating
losses (as measured by net earnings before interest and taxes and reflecting a
reasonable corporate overhead allocation) over any six (6) month period during
the Twenty-Four Month Period or if either the SAF or the IMS business incurs a
material adverse effect after the date hereof, then the Buyer shall have the
right to discontinue such business or to refuse to incur the capital
expenditures contemplated by Section 4.3.4 without having any obligation to pay
the Additional Consideration pursuant to this Section 4.3.

     4.4  Equity Adjustment.
          -----------------

          4.4.1  Within sixty (60) days after the Closing, the Sellers and the
Buyer shall jointly determine the Company's Net Equity (as defined below).  In
the event that the Net Equity is less than $2,800,000, Sellers shall pay to
Company (or the Buyer if it so directs) the amount by which the Net Equity is
less than $2,800,000.  In the event that the Net Equity is greater than
$2,800,000, Buyer or the Company shall pay to Sellers the amount by which the
Net Equity is greater than $2,800,000, but in no event shall the Buyer or the
Company be required to pay more than $500,000 to the Sellers pursuant to this
Section 4.4.  Any payments due hereunder shall be made within fifteen (15) days
after the Net Equity is finally determined without interest.  In the event that
the Sellers and the Buyer are unable to agree upon the Net Equity at Closing,
such dispute shall be resolved by an unaffiliated "Big Five" accounting firm to
be selected and agreed upon by the Sellers on the one hand and the Buyer on the
other hand (the "Unaffiliated Accounting Firm").  The dispute over the Net
Equity at Closing shall be resolved by the Unaffiliated Accounting Firm no later
than ninety (90) days after the Closing.  The costs, expenses and fees of the
Unaffiliated Accounting Firm shall be borne equally by the Buyer on the one hand
and the Sellers on the other hand.  Any payments to be made hereunder shall be
deemed an adjustment to the Purchase Price.

          4.4.2  For purposes of this Section 4.4, "Net Equity" shall mean the
excess of the Company's total assets over the Company's total liabilities, each
as determined in accordance

                                      13
<PAGE>

with United States Generally Accepted Accounting Principles ("GAAP"),
consistently applied, without regard to any deferred tax asset or liability. For
purposes of the calculation of the Net Equity, the total liabilities shall
include, among other things, (i) all accrued liability for processed or
unprocessed waste that is in the possession of the Company as determined by the
methodology agreed to by the parties and defined on Schedule 4.4.2 (ii) all
                                                    --------------
accrued liability relating to any loss contingency, if any, on the KAPL
contract.

5.   Confidentiality; Noncompetition.

     5.1. Confidentiality.  Each of the Sellers acknowledges and agrees that it
          ---------------
may possess certain data and knowledge of the Company, its business and its
operations which are proprietary in nature and confidential.  Each of the
Sellers agrees that neither it nor any of its affiliates will, at any time
hereafter, use for his or its own benefit, or reveal, divulge or make known to
any other person, firm, corporation or entity, any confidential information or
trade secrets regarding the Company, its business or its operations.  At the
Closing, Sellers shall deliver to the Company all lists of customers, books,
records and all other property constituting confidential information belonging
to the Company; provided, however, that the restrictions of this Section 5.1
shall not extend to any information which can be demonstrated to have been in
the public domain or thereafter entered the public domain other than through
disclosure by any of the Sellers or their agents or affiliates.  If at any time
a Seller is requested or required (by oral questions, interrogatories, requests
for information or documents, subpoenas or similar legal process) to disclose
any such information, the Seller (to the extent reasonably practical) shall
notify Buyer immediately and shall refrain from making such disclosure so that
Buyer may, at its own expense, seek an appropriate protective order and/or waive
compliance with the provisions hereof.  If, in the absence of a protective order
or the receipt of a waiver hereunder, in the reasonable opinion of the relevant
Seller's counsel, Sellers are compelled to disclose such information to any
tribunal or any governmental agency to avoid being liable for contempt or
suffering any other loss or penalty, such Seller may disclose such information
to such tribunal or agency without liability hereunder; provided, however, that
said Seller shall give Buyer prompt notice of such decision.  Sellers shall use
their best efforts to prevent their respective directors, officers,
stockholders, partners, owners, employees, agents and representatives from
violating the provisions of this Section 5.1.  For the purposes hereof, the term
"confidential information" shall include, but not be limited to, information

consultant were so employed or retained, Buyer or the Company would be put at a
competitive disadvantage) currently employed, retained or paid by the Company
and who the Buyer or the Company wishes to retain as an employee after the
acquisition hereunder. Sellers shall use their best efforts to prevent their
respective directors,

                                      14
<PAGE>

officers, stockholders, partners, owners, employees, agents and representatives

or relationships with any customer or prospective customer, (ii) solicit, deal
with or otherwise interfere with the continuance of supplies to the Company (or

the Company and any other party whatsoever.  Sellers shall use their best
efforts to prevent their respective directors, officers, stockholders, partners,
owners, employees, agents and representatives from violating the provisions of
this Section 5.3.  Notwithstanding the foregoing, the parties recognize that the
Sellers and their affiliates, through other business ventures, not engaged in
competition (defined in Section 5.4), engage in business dealings and ongoing

serving the Company.  The continuation or establishment of any such

capital stock of a corporation which engages in Competition if such capital
stock or other equity is a security which is actively traded on an established
national securities exchange.

          5.4.3  Each of the Sellers acknowledges and agrees that in view of the
nature of the Company's Business and the business objectives of the Buyer in
acquiring it, the foregoing territorial and time limitations are reasonable and
properly required for the adequate protection of Buyer and that in the event
that any such territorial or time limitation is deemed to be unreasonable, then
such limitations shall be automatically reduced to the maximum extent permitted
by a court of competent jurisdiction and, as reduced, the territorial and/or
time limitation shall be enforced.

     5.5. Specific Performance.  Sellers acknowledge that a violation of the
          --------------------
foregoing covenants of this Section 5 may cause irreparable injury to the

15.  Tax Matters.
     -----------

     15.1   Tax Indemnity. (a) The Sellers agree to indemnify and hold harmless
            -------------
the Buyer, the Company and HPI against Taxes imposed on the Company or HPI in
proportion to their direct or indirect ownership in the Company or HPI, with
respect to taxable periods or the portion of any taxable period ending on or
before the Closing Date (including any Tax imposed on the Company or HPI as a
result of the transfer of the claim for business interruption insurance
described in Section 1(a) hereof) and, except as otherwise provided in Section
15.4, against any loss, damage, liability or expense, including reasonable fees
for attorneys and other outside consultants, incurred in contesting or otherwise
in connection with any such Taxes. Notwithstanding the foregoing, the Sellers
shall not be required to indemnify Buyer for taxes payable as a result of any
election, amendment, or other change of any tax return made by Buyer, without
the consent of Seller. The Buyer shall be responsible for Taxes and associated
expenses not allocated to the Sellers pursuant to the first sentence hereof.

            (b) In the case of Taxes that are payable with respect to a taxable
period that begins before the Closing Date and ends after the Closing Date, the
portion of any such Tax that is allocable to the portion of the period ending on
the Closing Date shall be:

                (i)  in the case of Taxes that are either (x) based upon or
related to income or receipts, or (y) imposed in connection with any sale or
other transfer or assignment of property (real or personal, tangible or
intangible) (other than conveyances pursuant to this Agreement, as provided
under Section 15.7), deemed equal to the amount which would be payable if the
taxable year ended with the Closing Date and Buyer shall prepare books and
working papers (including a closing of the books) which will clearly demonstrate
the income and activities of the Company and HPI for the period ending on the
Closing Date and such post-closing partial period; and

                (ii) in the case of Taxes imposed on a periodic basis with
respect to the assets of the Company or otherwise measured by the level of any
item, deemed to be the amount of such Taxes for the entire period (or, in the
case of such Taxes determined on an arrears basis, the amount of such Taxes for
the immediately preceding period), multiplied by a fraction the numerator of
which is the number of calendar days in the period ending on the Closing Date
and the denominator of which is the number of calendar days in the entire
period.

            (c) Each of the Sellers agrees to indemnify the Buyer from and
against any Taxes Buyer may suffer resulting from, arising out of, relating to,
in the nature of, or caused by any liability of any of the Company, HPI or any
of their subsidiaries for Taxes of any other person (i) under Reg. Section
1.1502-6 (or any similar provision of state, local or foreign law), (ii) as a
transferee or successor, (iii) by contract, or (iv) otherwise; provided that
indemnity under clauses (iii) and (iv) shall be strictly limited to matters
disclosed by Buyer to Sellers on the Closing Date.

     15.2   Returns and Payments. (a) From the date of this Agreement through
            --------------------
and after the Closing Date, the Sellers shall prepare and file or otherwise
furnish in proper form to the appropriate governmental authority (or cause to be
prepared and filed or so furnished) in a timely manner all Tax returns, reports
and forms ("Returns") relating to the Company or HPI that are

                                      44
<PAGE>

due on or before or relate to any taxable period ending on or before the Closing
Date (and the Buyer shall do the same with respect to any taxable period ending
after the Closing Date). Returns of the Company or HPI not yet filed for any
taxable period that begins before the Closing Date shall be prepared in a manner
consistent with past practices employed with respect to the Company or HPI
(except to the extent counsel for the Sellers, the Company or HPI renders a
legal opinion that there is no reasonable basis in law therefor or determines
that a Return cannot be so prepared and filed without being subject to
penalties). With respect to any Return required to be filed by the Buyer with
respect to the Company or HPI and as to which an amount of Tax is allocable to
the Sellers under Section 15.1, the Buyer shall provide the Sellers and their
authorized representatives with a copy of such completed Return and a statement
certifying the amount of Tax shown on such Return that is allocable to the
Sellers pursuant to Section 15.1, together with appropriate supporting
information and schedules at least thirty (30) days prior to the due date
(including any extension thereof) for the filing of such Return, and the Sellers
and their authorized representatives shall have the right to review and comment
on such Return and statement prior to the filing of such Return. Each such
Return shall separately identify and reserve to the account of Buyer any Taxes
attributable to the exercise of any tax election, transfer, liquidation or other
event occurring or deemed to have occurred at or after the Closing Date and made
or effectuated by Buyer. With respect to any Return required to be filed by any
Seller with respect to the Company or HPI, the Sellers shall provide the Buyer
and its authorized representatives with a copy of such completed Return,
together with appropriate supporting information and schedules at least thirty
(30) days prior to the due date (including any extension thereof) for the filing
of such Return, and the Buyer and its authorized representatives shall have the
right to review and comment on such Return and statement prior to the filing of
such Return. Each party shall timely file any Return for which it is
responsible.

            (b) The Sellers shall pay or cause to be paid when due and payable
all Taxes with respect to the Company or HPI for any taxable period ending on or
before the Closing Date, and the Buyer shall so pay or cause to be paid all
Taxes for any taxable period after the Closing Date (subject to its right of
indemnification from the Sellers by the date set forth in Section 15.5 for Taxes
attributable to the portion of any Tax period that includes the Closing Date
pursuant to Section 15.1).

     15.3   Refunds. Any Tax refund (including any interest with respect
            -------
thereto) relating to the Company or HPI for any taxable period prior to the
Closing Date and as to which there is no corresponding increase in a Tax
attributable to any Seller, HPI, the Company or any affiliates for any other
taxable period shall be the property of the Buyer, and if received by the
Sellers, the Company or HPI shall be paid over promptly to the Buyer. In
addition, any Tax refund (or equivalent benefit to any Seller through a
reduction in Tax liability) for a period before the Closing Date arising out of
the carryback of a loss or credit incurred by the Company or HPI in a taxable
year ending after the Closing Date shall be the property of the Buyer and, if
received by such Seller, shall be paid over promptly to the Buyer, provided that
the Buyer shall indemnify each such Seller and hold such Settler harmless as to
any future claims made with respect to such refund by any and all taxing
authorities.

     15.4   Contests. (a) After the Closing, the Buyer shall promptly notify the
            --------
Sellers in writing or any written notice of a proposed assessment or claim in an
audit or administrative or

                                      45
<PAGE>

judicial proceeding of the Buyer, the Company or HPI which, if determined
adversely to the taxpayer, would be grounds for indemnification under this
Section 15.

            (b) In the case of an audit or administrative or judicial proceeding
that relates to periods ending on or before the Closing Date and provided that
the Sellers acknowledge in writing their liability under this Agreement to hold
the Buyer, the Company and HPI harmless against the full amount of any
adjustment which may be made as a result of such audit or proceeding that
relates to periods ending on or before the Closing Date (or, in the case of any
taxable year that includes the Closing Date, against an adjustment allocable
under Section 15.1(b) to the portion of such year ending on or before the
Closing Date) and is subject to indemnification under Section 15.1(a), the
Sellers shall have the right at their expense to participate in and control the
conduct of such audit or proceeding but only to the extent that such audit or
proceeding relates to a potential adjustment for which the Sellers have
acknowledged their liability; the Buyer also may participate in any such audit
or proceeding and, if the Sellers do not assume the defense of any such audit or
proceeding, the Buyer may defend the same in such manner as it may deem
appropriate, including, but not limited to, settling such audit or proceeding
after giving five (5) days' prior written notice to the Sellers setting forth
the terms and conditions of settlement. In the event that issues relating to a
potential adjustment for which the Sellers have acknowledged their liability are
required to be dealt with in the same proceeding as separate issues relating to
a potential adjustment for which the Buyer would be liable, the Buyer shall have
the right, at its expense, to control the audit or proceeding with respect to
the latter issues.

            (c) With respect to issues relating to a potential adjustment for
which both the Sellers (as evidenced by its acknowledgment under this Section
15.4) and the Buyer, the Company or HPI could be liable, (i) each party may
participate in the audit or proceeding, and (ii) the audit or proceeding shall
be controlled by that party which would bear the burden of the greater portion
of the sum of the adjustment and any corresponding adjustments that may
reasonably be anticipated for future Tax periods. The principle set forth in the
immediately preceding sentence shall govern also for purposes of deciding any
issue that must be decided jointly (including, without limitation, choice of
judicial forum) in situations in which separate issues are otherwise controlled
under this Section 15 by the Buyer and the Sellers.

            (d) Neither the Buyer nor any Seller shall enter into any compromise
or agree to settle any claim pursuant to any Tax audit or proceeding which would
adversely affect the other party for such year or a subsequent year without the
written consent of the other party, which consent may not be unreasonably
withheld. The Buyer and the Sellers agree to cooperate, and the Buyer agrees to
cause the Company or HPI to cooperate, in the defense against or compromise of
any claim in any audit or proceeding.

     15.5.  Time of Payment. Payment by the Sellers of any amounts due under
            ---------------
this Section 15 in respect of Taxes shall be made (i) at least five (5) days
before the due date of the applicable estimated or final Return required to be
filed by the Buyer on which is required to be reported income for a period
ending after the Closing Date for which any Seller is responsible under Sections
15.1(a) and 15.1(b) without regard to whether the Return shows overall net
income or loss for such period, and (ii) within five (5) days following an
agreement between the Sellers and

                                      46
<PAGE>

the Buyer that an indemnity amount is payable, an assessment of a Tax by a
taxing authority, or a "determination" as defined in Section 1313(a) of the
Code. If liability under this Section 15 is in respect of costs or expenses
other than Taxes, payment by any Seller of any amounts due under this Section 15
shall be made within five (5) days after the date on which the Sellers have been
notified by the Buyer that the Sellers have a liability for a determinable
amount under this Section 15 and is provided with calculations or other
materials supporting such liability.

     15.6.  Cooperation and Exchange of Information. Upon the terms set forth in
            ---------------------------------------
Section 14.2 of this Agreement, the Sellers and the Purchaser will provide each
other with such cooperation and information as either of them reasonably may
request of the other in filing any Return, amended Return or claim for refund,
determining a liability for Taxes or a right to a refund of Taxes, participating
in or conducting any audit or other proceeding in respect of Taxes or making
representations to or furnishing information to parties subsequently desiring to
purchase any of the Company or HPI or any part of the business from the Buyer.
Such cooperation and information shall include providing copies of relevant
Returns or portions thereof, together with accompanying schedules, related work
papers and documents relating to rulings or other determinations by Tax
authorities, as well as signing and delivering powers of attorney, information
authorization, closing or settlement agreements, and all other necessary or
appropriate documents. The Sellers shall make their employees available on a
basis mutually convenient to both parties to provide explanations of any
documents or information provided hereunder. Each of the Sellers and the Buyer
shall retain all Returns, schedules and work papers, records and other documents
in its possession relating to Tax matters of the Company and HPI for each
taxable period first ending after the Closing Date and for all prior taxable
periods until the later of (i) the expiration of the statute of limitations of
the taxable periods to which such Returns and other documents relate, without
regard to extensions except to the extent notified by the other party in writing
of such extensions for the respective Tax periods, or (ii) six years following
the due date (without extension) for such Returns. Any information obtained
under this Section 15.6 shall be kept confidential in accordance with Section
5.1 except as may be otherwise necessary in connection with the filing of
Returns or claims for refund or in conducting an audit or other proceeding.

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

assessments, judgments, costs, losses, liabilities and reasonable legal and
other expenses incident to any of the foregoing.

     Notwithstanding anything herein to the contrary, the fact that an item may
be disclosed on a schedule to this Agreement in response to a representation or
warranty contained herein shall not in any way limit any rights that an
indemnified party shall have to indemnification for any Losses resulting
therefrom, except to the extent a statement in such schedule expressly limits or
excludes any right to indemnity in respect thereof. The inclusion of an item on
a schedule attached hereto is merely for purposes of disclosure and not to
release any party from any liability therefor, except as may be otherwise
expressly provided on the schedule.

     16.2.  Indemnification by Buyer. Buyer shall indemnify each Seller and each
            ------------------------
of their officers, directors, employees, agents and affiliates and hold each of
them harmless at all times

                                      48
<PAGE>

from and after the Closing Date against and in respect of any Loss arising out

            16.2.1.  Any breach of representation or warranty or non-fulfillment
of any covenant or agreement on the part of the Buyer under this Agreement;

            16.2.2.  Any investigation, suit, action, claim or litigation
relating to the Company or HPI which may hereafter be brought against any of the

            16.2.3.  Any and all actions, suits, proceedings, claims, demands,
assessments, judgments, costs, losses, liabilities and reasonable legal and
other expenses incident to any of the foregoing.

     16.3.  Period of Indemnity. The aforesaid indemnities of Buyer and Sellers
            -------------------
shall remain in full force and effect: (a) as they relate to a third-party claim
against Buyer, each of the Sellers and the Company for a period equal to the
respective applicable statute of limitation for each such claim; and (b) as they
relate to breaches of representations, warranties or covenants made by Sellers
and Buyer, for the period provided in Section 17 hereof; provided, however, if
at the expiration of the appropriate period any claim or assessment for
indemnification has been asserted but not fully determined, or any audit or
other proceeding with respect to any tax matter has been initiated, such period
shall be extended as to such claim, assessment, audit or other proceeding until
it is finally determined or concluded.

     16.4.  Notice to the Indemnitor. Within a reasonable period after the
            ------------------------
assertion of any claim by a third party or occurrence of any event which may
give rise to a claim for indemnification from an Indemnitor (the "Indemnitor"`)
under this Section 16, an indemnified party (the "Indemnified Party") shall
notify the Indemnitor in writing of such claim together with a statement fully
describing the nature and amount of the claim and providing details with respect
thereto.

     16.5.  Rights of Parties to Settle or Defend. The Indemnitor may
            -------------------------------------
participate in and, at its option upon written acknowledgement of the
Indemnified Party's right to indemnification for such matter, assume the defense
of the Indemnified Party against such claim, including the employment of
counsel, who shall be reasonably acceptable to the Indemnified Party. In such
case, any Indemnified Party shall have the right to employ separate counsel in
any such action or claim and to participate in the defense thereof, but the fees
and expenses of such counsel shall not be at the expense of the Indemnitor
unless (i) the Indemnitor shall have failed, within ten (10) days after having
been notified by the Indemnified Party of the existence of such claim as
provided in the preceding sentence, to assume the defense of such claim, (ii)
the employment of such counsel has been specifically authorized in writing by
the Indemnitee or (iii) the named parties to any such action (including
impleaded parties) include both the Indemnified Party and the Indemnitor and
such Indemnified Party shall have been advised in writing by such counsel that
there may be conflicting interests between the Indemnified Party and the
Indemnitor in the legal defense thereof. The Indemnified Party shall make
available to the Indemnitor and its

                                      49
<PAGE>

attorneys and accountants, at all reasonable times during normal business hours,
all books, records, and other documents in its possession relating to such
claim. The party contesting any such claim shall be furnished all reasonable
assistance in connection therewith by the other party. If the Indemnitor fails
to undertake the defense of or, settle or pay any such third-party claim within
ten (10) days after the Indemnified Party has given written notice to the
Indemnitor advising that the Indemnified Party does not intend to contest such
claim, or the Indemnitor, after having given such notification to the
Indemnified Party, fails forthwith to defend, settle or pay such claim, then the
Indemnified Party may take any and all necessary action to dispose of such claim
including, without limitation, the settlement or full payment thereof upon such
terms as it shall deem appropriate, in its sole discretion, subject to the
following with respect to any proposed settlement thereof.

     16.6.  Settlement Proposals. In the event the Indemnified Party desires to
            --------------------
settle any such third-party claim (whether or not contested by the Indemnitor),
the Indemnified Party shall advise the Indemnitor of the amount it proposes to
pay in settlement thereof (the "Proposed Settlement"). If such Proposed
Settlement is unsatisfactory to the Indemnitor, it shall have the right, at its
expense, to contest such claim by giving written notice of such election to the
Indemnified Party within ten (10) days after the Indemnitor has been advised of
the Proposed Settlement. If the Indemnitor does not deliver such written notice
within ten (10) days after the Indemnitor has been advised of the Proposed
Settlement, the Indemnified Party may offer the Proposed Settlement to the third
party making such claim. If the Proposed Settlement is not accepted by the party
making such claim, any new Proposed Settlement which the Indemnified Party may
wish to present to the party making such claim shall first be presented to the
Indemnitor who shall have the right, subject to the conditions hereinabove set
forth in this Section, to contest such claim. In all such events, the Indemnitor
shall indemnify the Indemnified Party and hold it harmless against and from any
and all costs of defense, payment or settlement, including reasonable attorneys'
fees incurred in connection therewith.

     16.7.  Reimbursement. At the time that the Indemnified Party shall suffer
            -------------
an actual financial loss because of a breach of any warranty, representation or
covenant by the Indemnitor or at the time the amount of any liability on the
part of the Indemnitor under this Section is determined (which in the case of
payments to third persons shall be the earlier of (a) the date of such payments
or (b) the date that a court of competent jurisdiction shall enter a final
judgment, order or decree (after exhaustion of appeal rights establishing such
liability), the Indemnitor shall forthwith, upon notice from the Indemnified
Party, pay to the Indemnified Party, the amount of the indemnity claim. If such
amount is not paid forthwith, then the Indemnified Party may, at its option,
take legal action against the Indemnitor for reimbursement in the amount of its
indemnity claim. For purposes hereof the indemnity claim shall include the
amounts so paid (or finally determined to be owing) by the Indemnified Party
together with costs and reasonable attorneys' fees and interest on the foregoing
items at the prime rate in effect from time to time as published by the Wall
Street Journal, or any reasonable successor thereto during the period from the
date the obligation is due from the Indemnified Party to the Indemnitor, as
herein above provided, until the date paid.

     16.8.  Limitation on Indemnity. Notwithstanding anything herein to the
            ------------------------
contrary, Sellers shall be required to indemnify and hold harmless Buyer
hereunder only to the extent that

                                      50
<PAGE>

the aggregate amount of Buyer's claims hereunder exceeds the sum of Four Hundred
Thousand Dollars (USD $400,000). Notwithstanding anything herein to the
contrary, in no event shall Sellers be required to indemnify and hold harmless
Buyer hereunder for the amount, if any, by which the aggregate amount of Buyer's
claims hereunder exceeds the sum of Four Million Dollars (USD $4,000,000). The
limitations described in this Section 16.8 shall not apply to claims arising
under Sections 16.1.3 through 16.1.9 and any and all actions, suits,
proceedings, claims, demands, assesments, judgments, costs, losses, liabilities
and reasonable legal and other expenses incident to any items arising under
Sections 16.1.3 though 16.1.9. The duty of Sellers to indemnify Buyer shall not
apply at all to any Excluded Conditions as more fully described in Section
9.27.13.

     16.9   Indemnification Escrow. In order to secure the obligations of
            ----------------------
Sellers under Section 16, Sellers agree to enter into an Escrow Agreement
substantially in the form of Exhibit "E" attached hereto with Wilmington Trust
Company as the escrow agent.

     16.10  Waiver of Contribution. The Sellers shall not have any right to seek
            ----------------------
contribution from the Company or HPI in the event that any of the Sellers is
required to make any payments under this Section 16.

     16.11  Indemnification Covenants. (a) Buyer covenants and agrees that it
            ------------------------
will pursue indemnification claims hereunder first against the indemnification
escrow described in Section 16.9 hereof, to the extent of such escrow, before
pursuing claims directly against the Sellers.

            (b) HakeTenn covenants and agrees that it will maintain "tangible
net worth" (as defined below) of at least $3,000,000 until October 15, 2001, and
will maintain tangible net worth thereafter of at least $1,000,000 until October
15, 2002. Notwithstanding anything in this Agreement to the contrary, if Sellers
take any action, agree to take any action or fail to take any required action
that results in the extension of any statute of limitations for any liability
covered by Section 16.1.3 hereof beyond October 15, 2001, then the October 15,
2001 date for the permitted reduction of the tangible net worth shall be
extended to match the date to which the statute of limitations has been
extended. In order to assure compliance with this covenant, HakeTenn shall
provide upon request of Buyer unaudited financial statements of HakeTenn, which
shall include at least a balance sheet and income statement as of and for a
recent period, provided that such request shall be made no more frequently than
semi-annually. For purposes hereof, "tangible net worth" shall mean the excess
of HakeTenn's tangible assets over its total liabilities, each as determined in
accordance with GAAP.

17.  Survival of Representations and Warranties. All representations,
warranties, covenants and agreements made by each party in this Agreement, in
any Schedule annexed hereto or in any list, certificate, document or written
statement furnished or delivered by any such party pursuant hereto shall survive
the Closing, and shall remain in full force notwithstanding any investigation
conducted before or after the Closing or the decision of any party to complete
the Closing for a period of two (2) years following the Closing Date, unless
otherwise expressly provided herein; provided, however, that (a) all
representations and warranties made by Sellers with respect to tax matters shall
survive until the relevant statute of limitations with respect to each such item
has run and (b) if at the expiration of the appropriate

                                      51
<PAGE>

period any claim or assessment for indemnification has been asserted but not
fully determined, or any audit or other proceeding with respect to any tax
matter has been initiated, such period shall be extended as to such claim,
assessment, audit or other proceeding until it is finally determined or
concluded, and each party hereto shall be entitled to rely upon the
representations and warranties of the other party set forth in this Agreement.

result of Buyer's or any of its affiliates' dealings, arrangements or agreements

finders' fees in connection with the transactions contemplated by this Agreement
on behalf of the Buyer shall be the exclusive responsibility of the Buyer.

<PAGE>

     18.4.  Assignment and Binding Effect. This Agreement may not be assigned
            ------------------------------
by either party hereto without the prior written consent of the other party;
provided, however, Buyer may assign this Agreement to any of its subsidiaries or

remain liable for its obligations hereunder. All of the terms and provisions of
this Agreement shall be binding upon and inure to the benefit of and be
enforceable by the respective successors and assigns of the parties hereto.

     18.5.  Waiver. Any term or provision of this Agreement may be waived at

            18.6.1   Mutual Consent. By the consent of all the parties hereto;
                     --------------

            18.6.2   By Buyer. Unless Buyer shall be in default hereunder or
                     --------

resulted by reason of a breach by such party of any of its material obligations
