ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

         On February 23, 1998, Benchmark Electronics, Inc. ("Benchmark")
completed it previously announced acquisition (the "Acquisition") of all of the
outstanding stock of Lockheed Commercial Electronics Company ("LCEC") from
Lockheed Martin Corporation ("Lockheed") pursuant to the terms of a Purchase
Agreement dated as of January 22, 1998 by and between Benchmark and Lockheed
(the "Purchase Agreement"). As consideration for the Acquisition, Benchmark paid
$70 million in cash to Lockheed. The purchase price is subject to a post-closing
adjustment based on the net working capital of LCEC at the time of closing.

         LCEC is one of New England's largest electronics manufacturing services
company, providing a broad range of services including printed circuit board
assembly and test, system assembly and test, prototyping, depot repair,
materials procurement and engineering support services. Following the
Acquisition, LCEC is being operated as a division of Benchmark.

         The Purchase Agreement contains customary representations and
warranties of the parties which, except for certain representations of Lockheed
regarding environmental matters, survive the closing of the Acquisition for
varying time periods. The Purchase Agreement provides for indemnification by
Lockheed of Benchmark for breaches of surviving representations and warranties
to the extent damages exceed $1 million, for 60% of environmental liabilities
arising within four years after closing and relating to certain pre-existing
environmental conditions, and for specified pre-existing tax and employee
claims. Lockheed's aggregate indemnification liability is capped at the purchase
price. The Purchase Agreement provides for indemnification by Benchmark of
Lockheed for breaches of representations and warranties of Benchmark and for
damages resulting from the post-closing operation of LCEC. In connection with
the Acquisition, Benchmark agreed to lease the LCEC facility in Hudson, New
Hampshire from Lockheed for a two-year period with an option to renew the lease
for an additional four years.

         To finance a portion of the consideration for the Acquisition,
refinance existing revolving credit debt and provide for future working capital
needs, Benchmark on February 23, 1998 entered into a new Credit Agreement (the
"Credit Agreement") with Chase Bank of Texas, N. A. (the "Bank"). The Credit
Agreement provides for a $25 million revolving credit facility (the "Revolving
Credit Facility") and a $40 million term loan to be used for the Acquisition
(the "Term Loan"). Each of the Revolving Credit Facility and the Term Loan is
unsecured and guaranteed by each of Benchmark's United States subsidiaries.

         The Revolving Credit Facility matures, and the outstanding principal
amount is due, on March 31, 2003. Amounts outstanding under the Revolving Credit
Facility may not exceed the lesser of $25 million and the borrowing base, which
consists of 75% of eligible accounts receivable plus 25% of eligible inventory.
The Revolving Credit Facility also may be used for letters of credit of up to $5
million.

                                       -2-
<PAGE>
         The Term Loan must be repaid in quarterly installments of $2,000,000
beginning June 30, 1998, with the final installment becoming due on March 31,
2003

         Interest on the Revolving Credit Facility and the Term Loan accrues, at
Benchmark's option, at either the Bank's Eurodollar rate plus from .625% to
1.375% per annum or the Base Rate, which is the higher of the Bank's prime rate
and the federal funds rate plus .5%. The margin on the Eurodollar rate
fluctuates with Benchmark's ratio of debt to earnings before interest, taxes,
depreciation and amortization ("EBITDA"). Benchmark is required to pay a
commitment fee of .20% or .25% (depending on Benchmark's ratio of debt to
EBITDA) per annum on the unused portion of the Revolving Credit Facility.

         The Credit Agreement includes customary affirmative and negative
covenants, including financial covenants requiring Benchmark to maintain a
minimum tangible net worth, minimum current, fixed charge coverage and interest
coverage ratios and a maximum ratio of debt to EBITDA. The Credit Agreement also
restricts Benchmark's ability to incur additional indebtedness and to pay
dividends.

                                      - 1 -
<PAGE>
Purchaser to the Seller at the Closing by wire transfer of immediately available
funds. The Purchase Price shall be subject to adjustment as provided in Section
2.03.

         Section 2.03 ADJUSTMENT OF PURCHASE PRICE.

         (a) Promptly following the Closing Date, but in no event later than 60
days after the Closing Date, the Seller shall prepare and submit to the
Purchaser a statement of net working capital setting forth, in reasonable
detail, the Seller's calculation of the Net Working Capital of the Business as
of the close of business on the day prior to the Closing Date (the "Proposed
Final Net Working Capital Amount"). In the event the Purchaser disputes the
correctness of the Proposed Final Net Working Capital Amount, the Purchaser
shall notify the Seller of its objections within 30 days after receipt of the
Seller's calculation of the Proposed Final Net Working Capital Amount and shall
set forth, in writing and reasonable detail, the reasons for the Purchaser's
objections. If the Purchaser fails to deliver a notice of objections within such
time, the Purchaser shall be deemed to have accepted the Seller's calculation.
The Seller and the Purchaser shall endeavor in good faith to resolve any
disputed items within 20 days after the Seller's receipt of the Purchaser's
notice of objections. If they are unable to do so, the Purchaser and the Seller
shall select a nationally known independent accounting firm (other than Ernst &
Young LLP or KPMG Peat Marwick LLP to resolve the dispute (in a manner
consistent with Section 2.03(b) and with any items not in dispute), and the
determination of such firm in respect of the correctness of each item remaining
in dispute shall be conclusive and binding on the Seller and the Purchaser. The
Net Working Capital as of the close of business on the day prior to the Closing
Date as finally determined pursuant to this Section 2.03(a) (whether by failure
of the Purchaser to deliver notice of objection, by agreement of the Seller and
the Purchaser or by determination of the accountants selected as set forth
above) is referred to herein as the "Final Net Working Capital Amount."

         (b) The Proposed Final Net Working Capital Amount and the Final Net
Working Capital Amount shall be determined on a basis consistent with the manner
in which the Opening Statement was prepared as disclosed in the notes to the
Opening Statement or as otherwise set forth in Attachment II.

         (c) If the Final Net Working Capital Amount is greater than
$27,000,000, the difference between the Final Net Working Capital Amount and
$26,000,000 shall be paid to the Seller by the Purchaser with interest thereon
from the Closing Date to the date of payment at a rate per annum equal to the
per annum interest rate announced from time to time by Morgan Guaranty Trust
Company of New York as its prime rate in effect. If the Final Net Working
Capital Amount is less than $25,000,000, the difference between $26,000,000 and
the Final Net Working Capital Amount shall be paid to the Purchaser by the
Seller with interest thereon from the Closing Date to the date of payment at a
rate per annum equal to the per annum interest rate announced from time to time
by Morgan Guaranty Trust Company of New York as its prime rate in effect. If the
Final Net Working Capital Amount is equal to or within $1,000,000 of
$26,000,000, there shall be no adjustment to the Purchase Price. Such payment
shall be made in immediately available funds not later than two Business Days
after the determination of the Final Net Working Capital Amount by wire transfer
to a bank account designated by the party entitled to receive the payment. The
Purchase Price, as

                                      - 2 -
<PAGE>
finally adjusted pursuant to this Section 2.3 (but without regard to any
interest paid by the Seller or the Purchaser pursuant to this Section 2.3(c)),
is referred to herein as the "Adjusted Purchase Price."

         (d) The fees and expenses, if any, of the accounting firm selected to
resolve any disputes between the Seller and the Purchaser in accordance with
Section 2.03(a) shall be paid one-half by the Seller and one-half by the
Purchaser.

         Section 2.04 CLOSING. The closing (the "Closing") of the Contemplated
Transactions shall take place at the offices of Miles & Stockbridge, a
Professional Corporation, 10 Light Street, Baltimore, Maryland 21202, on
February 17, 1998; provided, however, that if all of the conditions to Closing
set forth in Article X have not been satisfied (or waived) as of that date and
if closing on that date therefore would be impractical, the Closing shall take
place on such other day as the parties to this Agreement may agree. The Closing
will occur at 9:00 a.m. on the Closing Date. At the Closing, among other things:

                  (i) the Purchaser shall pay and deliver to the Seller
         $70,000,000 in immediately available funds by wire transfer to an
         account designated by the Seller (which account shall be designated by
         the Seller by written notice to the Purchaser at least two Business
         Days prior to the Closing Date, or such shorter notice as the Purchaser
         shall accept);

                      (ii) the Seller shall deliver to the Purchaser a
         certificate or certificates representing all of the outstanding CE
         Shares accompanied by a stock power or powers duly endorsed by the
         Seller in blank;

                  (iii) the Seller and the Purchaser shall enter into a Supply
         Agreement in the form of Attachment III;

                  (iv) the Seller and the Purchaser shall enter into an Interim
         Services Agreement in the form of Attachment IV;

                  (v) the Seller and the Purchaser shall enter into (a) a lease
         for the CE Facility (the "CE Facility Lease") in the form of Attachment
         V, and (b) a sublease for that portion of the CE Facility currently
         occupied by the Seller's Sanders business unit in the form of
         Attachment VI (the "Sanders Sublease"); and

                  (vi) the Seller and the Purchaser shall enter into any other
         agreements reasonably necessary to give effect to the Contemplated
         Transactions.

financial reviews, investigations and studies as to the operation of the

the records of CE after the Closing, the Purchaser shall not have access to
personnel records of the Seller or CE relating to individual performance or
evaluation records, medical histories or other information which in the Seller's
good faith opinion is sensitive or the disclosure of which could subject the
Seller to risk of liability. Except as otherwise contemplated by Section 10.04,

shall operate as a waiver or otherwise affect any representation, warranty or
agreement given or made by the Seller hereunder.

other than those related to its prior ownership of the Business. Notwithstanding
the foregoing, the obligation of the Seller and its Affiliates to hold any such
information in confidence shall be satisfied if they exercise the same care with
respect to such information as they would take to preserve the confidentiality
of their own similar information.

         Section 5.03 NOTICES OF CERTAIN EVENTS. The Seller shall, promptly
after obtaining knowledge of the following, notify the Purchaser of:

(other than the Purchaser) relating to any acquisition or purchase of all or
part of the Business (whether by asset or stock sale, business combination
transaction or otherwise), or (ii) enter into or participate in any discussions
or negotiations regarding any of the foregoing, or furnish to any other Person

seek any of the foregoing.

solicitation (such as an advertisement) not specifically directed to employees
of CE.

bank at which any such lockbox or similar account is maintained to transfer any
payments made thereto to an account established by the Purchaser.

as appropriate to ensure compliance with any Applicable Laws (including, without
limitation, any requirements with respect to security clearances) and subject to
any applicable privileges (including, without limitation, the attorney-client

         Section 6.01 CONFIDENTIALITY. The Purchaser agrees that all information
provided or otherwise made available in connection with the Contemplated

such records relate have expired), and thereafter, shall not destroy or dispose
of such records without giving notice to the Seller of such pending disposal and
offering the Seller the right to copy or take possession of such records. From

will be insured under any insurance policies

maintained by the Seller or any of its Affiliates, except (i) in the case of
certain policies, to the extent that a claim has been reported as of the Closing

From and after the Closing Date, neither the Seller nor any of its Affiliates

under the terms of this Agreement.

         (c) The Purchaser agrees that, to the extent any of the insurers under
any of the insurance policies maintained by the Seller or any of its Affiliates,
in accordance with the terms of the insurance policies, requests or requires
collateral, deposits or other security to be provided with respect to claims
made against such insurance policies relating to or arising from the business of

obligations of the Seller and its Affiliates under such Financial Support
Arrangement in accordance with Section 6.03(d), (ii) December 31, 1998 and (iii)
the date such

                                      - 9 -

Financial Support Arrangement terminates in accordance with its terms. After the
Closing Date and prior to the Release Date for any such Financial Support
Arrangement, the Seller will not waive any requirements of or agree to amend
such Financial Support Arrangement without the prior written consent of the
Purchaser.

under any Financial Support Arrangement where the Seller or any of its
Affiliates is obligated to reimburse the Person making such payment or (ii) the
Seller or any of its Affiliates pays any amounts under, or any fees, costs or
expenses relating to, any Financial Support Arrangement, the Purchaser shall pay
the Seller such amounts promptly after receipt from the Seller of notice thereof

equal to the aggregate principal or stated amount, as may be applicable, of the
Financial Support Arrangements not so released or (ii) subject to the prior
approval of the Seller, provide back-up letters of credit in form and substance
satisfactory to the Seller with respect to such Financial Support Arrangements.
Any cash deposited with the Seller in accordance with clause (i) shall be held
by the Seller in a segregated account and shall be used by the Seller solely to
satisfy its payment obligations in respect of such Financial Support
Arrangements, and the unused portion of any cash relating to a Financial Support
Arrangement shall be returned to the Purchaser promptly after the occurrence of

or indirectly solicit any individual who is an employee of the Seller or any of
its Subsidiaries (other than CE) at any time on or after the date of this
Agreement to terminate his or her relationship with the Seller or any of its
Subsidiaries; provided, however, that the foregoing shall not apply to
individuals hired as a result of the use of an independent employment agency (so
long as the agency was not directed to solicit a particular individual or a
class of individuals that could only be satisfied by employees of the Seller or
any of its Subsidiaries (other than CE) on the Closing Date) or as a result of
the use of a general solicitation (such as an advertisement) not specifically
directed to employees of the Seller or any of its Subsidiaries.

         Section 6.05 USE OF CERTAIN TRADEMARKS, ETC. The Purchaser acknowledges
and agrees that it is not obtaining any rights or licenses with respect to the
names "Lockheed Martin Corporation," "Lockheed Corporation," "Martin Marietta
Corporation," "Loral Corporation," "Sanders" or any derivative thereof, or to
their logos or trade dress, or to any other Intellectual Property Rights not
owned by CE or licensed to CE. As soon as practicable following the Closing, the
Purchaser shall take all actions necessary to cause CE to change its corporate
name so as not to include the word "Lockheed." As soon as practicable following
the Closing, but no later than 90 days after the Closing Date, the Purchaser
shall remove and change signage, change and substitute promotional

                                     - 10 -
<PAGE>
and advertising material in whatever medium, change stationery and packaging and
take all such other steps as may be required or appropriate to cease use of all
such Intellectual Property Rights not owned by CE. The Seller agrees that during
the 90-day period contemplated by the preceding sentence CE shall be authorized
to continue to use the words "Lockheed" and "Lockheed Martin" in connection with

purposes for which such words are being used by CE on the date of this
Agreement.

         Section 6.06 INTERCOMPANY ACCOUNTS. The Purchaser shall take, and shall
cause CE to take, all actions and to do, or cause to be done, all things
necessary, proper and appropriate to give effect to the contribution to the
equity of CE all net intercompany amounts contemplated to be contributed,
eliminated or cancelled on or prior to the Closing Date by Section 5.08.


                                   ARTICLE VII

                            COVENANTS OF THE PARTIES

         Section 7.01 FURTHER ASSURANCES. Subject to the terms and conditions of
this Agreement, each party shall use all reasonable commercial efforts to take,
or cause to be taken, all actions and to do, or cause to be done, all things
necessary or desirable under Applicable Laws to consummate the Contemplated
Transactions. The Seller and the Purchaser shall execute and deliver such other
documents, certificates, agreements and other writings and to take such other
actions as may be necessary or desirable in order to consummate or implement
expeditiously the Contemplated Transactions. Except as otherwise expressly set
forth in this Agreement, nothing in this Section 7.01 shall require the Seller
or the Purchaser to make any payments in order to obtain any consents or
approvals necessary or desirable in connection with the consummation of the
Contemplated Transactions.

         Section 7.02 CERTAIN FILINGS; CONSENTS. The Seller and the Purchaser
shall cooperate with one another (i) in determining whether any action by or in
respect of, or filing with, any Governmental Authority is required, or any
actions, consents, approvals or waivers are required to be obtained from parties
to any material Contracts, in connection with the consummation of the
Contemplated Transactions and (ii) subject to the terms and conditions of this
Agreement, in taking such actions or making any such filings, furnishing
information required in connection therewith and seeking timely to obtain any
such actions, consents, approvals or waivers.

         Section 7.03 PUBLIC ANNOUNCEMENTS. The Seller and the Purchaser shall
consult with each other before issuing any press release or making any public
statement with respect to this Agreement or the Contemplated Transactions and,
except as may be required by Applicable Law or any listing agreement with any
national or international securities exchange, will not issue any such press
release or make any such public statement prior to such consultation.
Notwithstanding the foregoing, no provision of this Agreement shall relieve the
Purchaser from any of its obligations under the Purchaser Confidentiality
Agreement or terminate any of the restrictions imposed by Section 6.01.

         Section 7.04 HSR ACT. The parties shall take all actions necessary or
appropriate to cause the prompt expiration or termination of any applicable
waiting period under the HSR Act in respect of the Contemplated Transactions,
including, without limitation, complying as promptly as practicable with any
requests for additional information.

         Section 7.05 ENVIRONMENTAL INSURANCE CLAIMS. Notwith-standing any
provision to the contrary in this Agreement, this Section 7.05 shall constitute
the parties' agreement regarding the allocation of insurance proceeds with
respect to claims for liabilities that arise under or relate to Environmental
Laws that are comprised, in whole or in part, of Environmental Liabilities (the
"Environmental Insurance Claims"). The Purchaser acknowledges that the Seller
shall control the Environmental Insurance Claims and shall have the right to
compromise or settle any Environmental Insurance Claims; provided, however, that
without the prior written consent of the Purchaser, the Seller shall not have
the right to enter into, and the Purchaser and CE shall not be bound by, any
compromise or settlement of any Environmental Insurance Claim that (i) imposes
any liability, obligation or responsibility on CE or the Purchaser or (ii)
imposes any condition, restriction or limitation on the operation or conduct of
the business of CE or the Purchaser, or on CE's property or the CE Facility. The
Seller will act in good faith and with reasonable prudence to maximize recovery
with respect to the Environmental Insurance Claims and will allocate any
recovery received with respect to such Environmental Insurance Claims, first, to
the costs it incurred to collect such recovery, and second, to reimburse any
Governmental Authority, prime contractor or subcontractor pursuant to a contract
with the U.S. Government.

         With respect to any recovery remaining (the "Remaining Recovery"):

                  (i) if the recovery applies to liabilities that are
         liabilities of CE and to liabilities that are not liabilities of CE,
         and the recovery was not designated as arising from specific
         liabilities (e.g., a global settlement with an insurance carrier), the
         Seller will pay the Purchaser an amount equal to the Remaining Recovery
         multiplied by X multiplied by (one minus Y); where X equals the total
         of the Environmental Insurance Claims (estimated in good faith and upon
         a reasonable basis as of the date of recovery) under the applicable
         insurance policies divided by the total environmental and other claims
         by the Seller under said insurance policies; and Y equals the Seller's
         past expenditures on said liabilities divided by the sum of (A) the
         Seller's past expenditures on said liabilities and (B) the total
         estimated expenditures to be made by the Seller or the Purchaser in
         respect of said liabilities (estimated in good faith and upon a
         reasonable basis as of the date of recovery), or

             (ii) if the recovery was designated as arising from specific
         liabilities of CE, the Seller will pay the Purchaser the Remaining
         Recovery multiplied by (one minus Y).

To the extent that any Remaining Recovery is insufficient to satisfy any
Environmental Liabilities, the responsibility of the Seller, on the one hand,
and the Purchaser and CE, on the other hand, for such additional amounts shall
be governed by the other provisions of this Agreement, including, without
limitation, the proviso to the second sentence of this Section 7.05.

         reasonably satisfactory to the Seller and the Purchaser shall have
         rendered a written opinion that there is a substantial likelihood of a
         determination that would prohibit the Closing;

                  (iii) All actions by or in respect of or filings with any
         Governmental Authority required to permit the consummation of the
         Closing shall have been obtained;

                  (iv) The Seller and the Purchaser shall have executed and

         Seller in blank.

         Section 10.02 CONDITIONS TO OBLIGATION OF THE PURCHASER. The
obligations of the Purchaser to consummate the Closing are subject to the
satisfaction (or waiver by the Purchaser) of the following further conditions:
(i) the Seller shall have performed in all material respects all of its
obligations under this Agreement required to be performed by it on or prior to
the Closing Date, (ii) the representations and warranties of the Seller
contained in this Agreement (except for representations and warranties that by
their terms speak only as of the date of this Agreement) shall be accurate at
and as of the Closing Date, as if made at and as of such date, except for any
inaccuracies which, individually or in the aggregate, have not had or may not
reasonably be expected to have, a Material Adverse Effect on CE and (iii) the
Purchaser shall have received a certificate signed by an officer of the Seller
to the foregoing effect.

         Section 10.03 CONDITIONS TO OBLIGATION OF THE SELLER. The obligation of
the Seller to consummate the Closing is subject to the satisfaction (or waiver

or in the aggregate, have not had, and may not reasonably be expected to have, a
Material Adverse Effect on the Seller, and (iii) the Seller shall have received
a certificate signed by an officer of the Purchaser to the foregoing effect.

         Section 10.04 UPDATING DISCLOSURE SCHEDULES. At any time prior to the
Closing the Seller shall be entitled to deliver to the Purchaser updates to or
substitutions of the Disclosure Schedules provided that such updates or
substitutions are clearly marked as such and are addressed to the Purchaser at
the address listed in Section 13.01. In the event that the Seller delivers
updated or substitute Disclosure Schedules on or after the third day before any
scheduled closing date, the Purchaser shall be entitled to extend the scheduled
closing date to the third day after it receives the updated or substitute
Disclosure Schedule, or if such day is not a Business Day, to the next Business
Day. The delivery by the Seller of updated or substitute Disclosure Schedules
shall not prejudice any rights of the Purchaser under this Agreement, including
but not limited to the right to claim that the representations and warranties of
the Seller, when made on the date of this Agreement, were untrue; provided,
however, that if the Purchaser decides not to assert any such claim and

                            SURVIVAL; INDEMNIFICATION

         Section 11.01 SURVIVAL.

         (a) The covenants, agreements, representations and warranties of the
parties contained in this Agreement or in any certificate or other writing
delivered pursuant to this Agreement or in connection with this Agreement shall
survive the Closing, as follows:

                  (i) the representations and warranties in Sections B.01, B.02,
         B.03, B.04, B.05 and B.14 shall survive indefinitely;

                  (ii) the representations and warranties in Section B.15 shall
         not survive the Closing;

                  (iii) the representations and warranties in Exhibit B (other
         than those Sections of Exhibit B referenced in the preceding clauses
         (i) and (ii)) shall survive for a period of two years from the Closing
         Date;

                  (iv) the representations and warranties in Exhibit D shall
         survive until the expiration of the applicable statute of limitations;

                  (v) the representations and warranties in Sections C.01, C.02,

                  (vii) those covenants and agreements set forth in this
         Agreement that, by their terms, are to have effect after the Closing

The representations, warranties, covenants and agreements referenced in the

Covenants shall expire at the respective expiration dates stated above, except
for claims for any misrepresentation or breach of any Surviving Representation
or Covenant made in writing and received by the party against whom such

                                     - 15 -

prior to the applicable expiration date stated above. It is understood and
agreed that, except for liabilities based on fraud and except as expressly
provided in this Agreement, after the Closing there shall be no liability or
obligation in respect of a breach or alleged breach of any representation,
warranty, covenant and other agreement, and that after the Closing the exclusive
remedies as between the Purchaser and its Affiliates (including CE following the
Closing) on the one hand, and the Seller and its Affiliates on the other hand,
for Damages (whether by contract, in tort or otherwise, and whether in law, in
equity or otherwise) in respect of the Business or CE shall be those remedies
expressly provided in this Agreement.

         (b) Except as otherwise provided in this Agreement, the Purchaser for
itself, its Affiliates (including CE following the Closing) and their respective
Representatives, effective as of the Closing, releases and discharges the
Seller, its Affiliates and their respective Representatives from any and all
Damages (whether by contract, in tort or otherwise, and whether in law, in
equity or otherwise), rights of subrogation and contribution and remedies of any
nature whatsoever, known or unknown, relating to or arising out of Environmental
Liabilities or Environmental Laws, in either case, arising in connection with or
in any way relating to the Business or CE.

         Section 11.02 INDEMNIFICATION.

         (a) Effective as of the Closing, the Purchaser hereby indemnifies the
Seller and its Affiliates and their respective directors, officers, employees
and agents against, and agrees to hold them harmless from, any and all Damages
incurred or suffered by any of them arising out of or related in any way to (i)
any misrepresentation or breach of any Surviving Representation or Covenant made
or to be performed by the Purchaser pursuant to this Agreement, (ii) any
Financial Support Arrangement referred to in Section 6.03, (iii) any matters for
which indemnification is provided under Exhibits D and E (it being understood
that such indemnification will be governed by and subject to the terms of such
Exhibits), or (iv) any liabilities arising in connection with or in any way
relating to the Business (but only as conducted on or after the Closing Date),
CE or the CE Facility (but only during a period in which the Purchaser or CE or
any of their Affiliates or successors owns or leases the CE Facility), or the
Purchaser's or CE's or any other Person's use, ownership or operation thereof
(but, with respect to the CE Facility, only during a period in which the
Purchaser or CE or any of their Affiliates or successors owns or leases the CE
Facility), whether vested or unvested, contingent or fixed, actual or potential,
which arise under or relate to Environmental Laws to the extent such liabilities
arise out of, relate to, are based on or result from any action taken (or a
failure to take action) or any event occurring on or after the Closing Date,
including, without limitation, (A) Remedial Actions, (B) personal injury,
wrongful death, economic loss or property damage claims, (C) claims for natural
resource damages, (D) violations of law or (E) any other Damages with respect
thereto.

         (b) Effective as of the Closing and subject to the limitations set
forth in Section 11.04, the Seller hereby indemnifies the Purchaser and its
Affiliates and their respective directors, officers, employees and agents
against, and agrees to hold them harmless from, any and all Damages incurred or
suffered by any of them arising out of or related in any way to (i) any
misrepresentation or breach of any Surviving Representation or Covenant made or
to be performed by the Seller pursuant to this

                                     - 16 -
<PAGE>
Agreement, (ii) any Environmental Liabilities to the extent arising out of,
relating to, based on or resulting from actions taken (or failure to take
action), conditions existing or events occurring prior to the Closing, (iii) any
Indemnified Pre-Closing Claims and any matters for which indemnification is
provided under Exhibits D and E (it being understood that such indemnification
will be governed by and subject to the terms of such Exhibits) or (iv) any (A)
workers compensation claims, (B) claims contemplated by Item 2 in Schedule B.10,
and (C) claims contemplated by Item 4 in Schedule B.11, but in each case only to
the extent attributable to a time, or arising out of, relating to, based on or
resulting from any action (or failure to act), conditions existing or events
occurring, prior to the Closing Date.

         Section 11.03 PROCEDURES.

         (a) If the Seller or any of its Affiliates or any of their directors,
officers, employees or agents shall seek indemnification pursuant to Section
11.02(a), or if the Purchaser or any of its Affiliates or any of their
directors, officers, employees or agents shall seek indemnification pursuant to
Section 11.02(b), such Person seeking indemnification (the "Indemnified Party")
shall give written notice to the party from whom such indemnification is sought
(the "Indemnifying Party") promptly after the Indemnified Party (or, if the
Indemnified Party is a corporation, any officer of the Indemnified Party)
becomes aware of the facts giving rise to such claim for indemnification (an
"Indemnified Claim") specifying in reasonable detail the factual basis of the
Indemnified Claim, stating the amount of the Damages, if known, the method of
computation thereof, and containing a reference to the provision of this
Agreement in respect of which such Indemnified Claim arises. The failure of an
Indemnified Party to provide notice pursuant to this Section 11.03 shall not
constitute a waiver of that party's claims to indemnification pursuant to
Section 11.02 in the absence of material prejudice to the Indemnifying Party. If
the Indemnified Claim arises from the assertion of any claim, or the
commencement of any suit, action or proceeding brought by a Person that is not a
party hereto (a "Third Party Claim") any such notice to the Indemnifying Party
shall be accompanied by a copy of any papers theretofore served on the
Indemnified Party in connection with such Third Party Claim.

         (b)      (i) Upon receipt of notice of a Third Party Claim from an
         Indemnified Party pursuant to Section 11.03(a), the Indemnifying Party
         will, subject to the provisions of Section 11.03(b)(ii) and (iii),
         assume the defense and control of such Third Party Claim but shall
         allow the Indemnified Party a reasonable opportunity to participate in
         the defense thereof with its own counsel and at its own expense. The
         Indemnifying Party shall select counsel, contractors and consultants of
         recognized standing and competence after consultation with the
         Indemnified Party; shall take all steps necessary in the defense or
         settlement thereof; and shall at all times diligently and promptly
         pursue the resolution thereof. In conducting the defense thereof, the
         Indemnifying Party shall at all times act as if all Damages relating to
         such Third Party Claim were for its own account and shall act in good
         faith and with reasonable prudence to minimize Damages therefrom. The
         Indemnified Party shall, and shall cause each of its Affiliates,
         directors, officers, employees, and agents to, cooperate fully with the
         Indemnifying Party in the defense of any Third Party Claim defended by
         the Indemnifying Party.

<PAGE>
                  (ii) Subject to the provisions of Section 11.03(b)(iii), the
         Indemnifying Party shall be authorized to consent to a settlement of,
         or the entry of any judgment arising from, any Third Party Claims,
         without the consent of any Indemnified Party; provided, that the
         Indemnifying Party shall (1) pay or cause to be paid all amounts
         arising out of such settlement or judgment concurrently with the
         effectiveness thereof; (2) shall not encumber any of the assets of any
         Indemnified Party or agree to any restriction or condition that would
         apply to such Indemnified Party or to the conduct of that party's
         business; and (3) obtain, as a condition of any settlement or other
         resolution, a complete release of each Indemnified Party.

                  (iii) An Indemnified Party may elect to share the defense of a
         Third Party Claim the defense of which has been assumed by the
         Indemnifying Party pursuant to Section 11.03(b)(i). In that event, the
         Indemnified Party will so notify the Indemnifying Party in writing.
         Thereafter, the Indemnifying Party and the Indemnified Party shall
         participate on an equal basis in the defense, management and control of
         any such claim. The Indemnifying Party and the Indemnified Party shall
         select mutually satisfactory counsel, contractors and consultants to
         conduct the defense or settlement thereof, and shall at all times
         diligently and promptly pursue the resolution thereof. The Indemnifying
         Party and the Indemnified Party shall each be responsible for one-half
         of all Damages incurred after the Indemnified Party has provided notice
         as provided in this clause (iii), including costs of defense and
         investigation, in respect of any such claim, provided that the election
         of the Indemnified Party to share in the defense of a Third Party Claim
         as to which indemnity is available pursuant to Section 11.02(b)(i) or
         Section 11.02(b)(ii) shall not increase the Seller's liability beyond
         that contemplated by Section 11.04.

                  (iv) In the case of the indemnification contemplated by clause
         (ii) of Section 11.02(b), in the event that either the Indemnified
         Party or the Indemnifying Party desires to settle the matters
         referenced therein or consent to the entry of any judgment arising
         thereunder and the other party does not wish to consent to such
         settlement, the other party shall have no obligation to consent to the
         settlement provided that it agrees in writing to pay and be responsible
         for 100% of any Damages thereafter incurred; provided that no
         Indemnified Party shall be required to consent to any settlement or
         agree to be responsible for the payment of Damages thereafter incurred
         with respect to any matter the settlement of which would require the
         consent of such Indemnified Party pursuant to Section 11.03(b)(ii). The
         obligation of the party that rejects any proposed settlement offer or
         entry of any such judgment to pay and be responsible for 100% of any
         Damages thereafter incurred in accordance with this Section
         11.03(b)(iv) shall be conditioned upon and subject to the payment,
         within five Business Days of the date such party provides the written
         agreement contemplated by the preceding sentence, of an amount, in
         immediately available funds, equal to the portion of the total
         settlement that would have been payable by the party desiring to settle
         the matter or consent to the entry of any such judgment according to
         the percentage sharing arrangement contemplated by Section 11.04(ii).
         Thereafter, the party that rejects the proposed settlement shall be
         solely responsible for the defense of the matter that is the subject of
         the proposed settlement.

         (c) If the Indemnifying Party and the Indemnified Party are unable to
agree with respect to a procedural matter arising under Section 11.03(b)(iii),
the Indemnifying Party and the Indemnified Party shall, within 10 days after
notice of disagreement given by either party, agree upon a third-party referee
("Referee"), who shall be an attorney and who shall have the authority to review
and resolve the disputed matter. The parties shall present their differences in
writing (each party simultaneously providing to the other a copy of all
documents submitted) to the Referee and shall cause the Referee promptly to
review any facts, law or arguments either the Indemnifying Party or the
Indemnified Party may present. The Referee shall be retained to resolve specific
differences between the parties within the range of such differences. Either
party may request that all oral arguments presented to the Referee by either
party be in each other's presence. The decision of the Referee shall be final
and binding unless both the Indemnifying Party and the Indemnified Party agree
otherwise. The parties shall share equally all costs and fees of the Referee.

         Section 11.04 LIMITATIONS. Notwithstanding anything to the contrary in
this Agreement, except for liability based on fraud, the Seller shall only have
liability to the Purchaser or any other Person hereunder:

                  (i) with respect to the matters described in Section
         11.02(b)(i), to the extent that the aggregate Damages suffered by an

         such time period; and

                  (iii) by either the Seller or the Purchaser if there shall be

                  REPRESENTATIONS AND WARRANTIES OF THE SELLER

         The Seller hereby represents and warrants to the Purchaser that:

         B.01. CORPORATE EXISTENCE AND POWER. Each of the Seller and CE is a
corporation duly incorporated, validly existing and in good standing under the
laws of its state of incorporation and has all corporate powers and all material
governmental licenses, authorizations, consents and approvals required to carry
on its business as now conducted. Each of the Seller and CE is duly qualified to
do business as a foreign corporation and is in good standing in each
jurisdiction where such qualification is necessary, except for those
jurisdictions where the failure to be so qualified would not have a Material
Adverse Effect on CE. Each of the Seller and CE has heretofore delivered to the
Purchaser true and complete copies of its charter or certificate of
incorporation and bylaws as currently in effect.

         B.02. CORPORATE AUTHORIZATION. The execution, delivery and performance
by the Seller of this Agreement, the Supply Agreement, the Interim Services
Agreement, the CE Facility Lease and the Sanders Sublease, and the consummation
by the Seller and CE of the Contemplated Transactions, are within its corporate
powers and have been duly authorized by all necessary corporate action on the
part of the Seller. Each of this Agreement, the Supply Agreement, the Interim
Services Agreement, the CE Facility Lease and the Sanders Sublease constitutes
or, in the case of agreements to be executed at Closing, will constitute at the
Closing a legal, valid and binding agreement of the Seller enforceable against
the Seller in accordance with its terms (i) except as limited by applicable
bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereafter in effect relating to or affecting creditors' rights generally,
including the effect of statutory and other laws regarding fraudulent
conveyances and preferential transfers and (ii) subject to the limitations
imposed by general equitable principles (regardless of whether such
enforceability is considered in a proceeding at law or in equity).

         B.03. CAPITALIZATION.

                  (a) The authorized capital stock of CE consists of 10,000
         shares of Common Stock, par value $1.00 per share, 1,000 of which are
         outstanding.

                  (b) All outstanding CE Shares have been duly authorized and
         validly issued and are fully paid and non-assessable. Except as set
         forth in Schedule B.03 of the Disclosure Schedule, there are no (i)
         outstanding shares of capital stock or voting securities of CE, (ii)
         securities of CE convertible into or exchangeable for shares of capital
         stock or voting securities of CE or options or other rights to acquired
         from CE, or (iii) other obligations of CE to issue, any capital stock,
         voting securities or securities convertible into or exchangeable for
         capital stock or voting securities of CE (the items in the foregoing
         clauses (i), (ii) and (iii) being referred to collectively as the
         "Company

                                       B-1
<PAGE>
         Securities"). There are no outstanding obligations of CE to repurchase,
         redeem or otherwise acquire any Company Securities.

         B.04. OWNERSHIP OF CE SHARES. The Seller is the record and beneficial
owner of the CE Shares, free and clear of any Lien and any other contractual
limitation or restriction (including the right to vote, sell or otherwise
dispose of the CE Shares), and will transfer to the Purchaser at the Closing
valid title to the CE Shares.

         B.05. GOVERNMENTAL AUTHORIZATION. The execution, delivery and
performance by the Seller of this Agreement, the Supply Agreement, the Interim
Services Agreement, the CE Facility Lease and the Sanders Sublease, and the
Contemplated Transactions, require no action by or in respect of, or consent or
approval of, or filing with, any Governmental Authority other than:

                  (i) compliance with any applicable requirements of the HSR
         Act;

                  (ii) those actions, consents, approvals or filings set forth
         on Schedule B.05 of the Disclosure Schedule; and

                  (iii) any actions, consents, approvals or filings the failure
         to make or obtain could not reasonably be expected to have a Material
         Adverse Effect on the Business.

         B.06. NON-CONTRAVENTION. Except as set forth in Schedule B.06 of the
Disclosure Schedule, the execution, delivery and performance by the Seller of
this Agreement, the Supply Agreement, the Interim Services Agreement, the CE
Facility Lease and the Sanders Sublease, and the consummation of the
Contemplated Transactions, do not and will not (i)(A) contravene or conflict
with the charter (or certificate of incorporation, as the case may be) or bylaws
of the Seller or CE, (B) assuming compliance with the matters referred to in
Section B.05, contravene or conflict with or constitute a violation of any
provisions of any Applicable Law, rule, regulation, judgment, injunction, order
or decree binding upon or applicable to the Business; (C) assuming compliance
with the matters referred to in Section B.05, constitute a default under or give
rise to any right of termination, cancellation or acceleration of, or to a loss
of any benefit relating to the Business to which the Seller or CE is entitled
under any provision of any Contract, agreement or other instrument binding upon
the Seller or CE, or by which any of the assets of CE is or may be bound,
except, in the case of clauses (i)(B) and (i)(C), for any such contravention,
conflict, violation, default, termination, cancellation, acceleration or loss
that could not reasonably be expected to have a Material Adverse Effect on the
Business or (ii) result in the creation or imposition of any Lien on any assets
of CE, other than Permitted Liens.

         B.07. OPENING STATEMENT. The Opening Statement presents fairly, in all
material respects, the net assets of the Business as of December 28, 1997, in
conformity with GAAP (except as otherwise contemplated by Attachment II under
the heading "Exceptions to GAAP in the Opening Statement") and the manner in
which CE currently reports its financial position for consolidation in the
financial statements of the Seller.

                                       B-2

         B.08. ABSENCE OF CERTAIN CHANGES. Except as set forth in Schedule B.08

conducted in the ordinary course consistent with past practice and there has not
been:

                  (a) any incurrence, assumption or guarantee by the Seller or
         CE of any indebtedness for borrowed money with respect to the Business;

                  (b) any creation or other incurrence of any Lien (other than
         Permitted Liens) on any asset of CE other than in the ordinary course
         of business consistent with past practices;

                  (c) any damage, destruction or other casualty loss (whether or
         not covered by insurance) affecting the Business, the CE Facility or
         any asset of CE which, individually or in the aggregate, has had or
         could reasonably be expected to have a Material Adverse Effect on CE;

                  (d) any transaction or commitment made, or any Contract or
         agreement entered into, by Seller or CE relating to the Business, the
         CE Facility or any asset of CE (including the acquisition or
         disposition of any assets) or any relinquishment by Seller or CE of any
         contract or other right, in either case, other than (i) transactions
         and commitments in the ordinary course of business consistent with past
         practices, (ii) those contemplated by this Agreement, and (iii) those
         that could reasonably be expected to have a Material Adverse Effect on
         the Business;

                  (e) any change in any method of accounting or accounting
         practice by Seller or CE with respect to the Business, except for
         changes required by GAAP; or

                  (f) any capital expenditure, or commitment for a capital
         expenditure, for additions or improvements to property, plant and
         equipment involving an amount in the aggregate in excess of $2,000,000.

         B.09. SUFFICIENCY OF AND TITLE TO ASSETS.

                  (a) The assets of the Business (including the CE Facility),
         together with the services to be provided to the Purchaser pursuant to
         the Interim Services Agreement, constitute, and on the Closing Date
         will constitute, all of the assets and services that are necessary to
         permit the operation of the Business in substantially the same manner
         as such operations have heretofore been conducted.

                  (b) Schedule B.09 of the Disclosure Schedule correctly
         describes all real property used or held for use primarily in the
         Business (the "Real Property"), which the Seller or CE owns, leases,
         operates or subleases, and any Liens thereon (other than Permitted
         Liens), specifying in the case of leases or subleases, the name of the
         lessor or sublessor, the lease term and basic annual rent.

                  (c) The Seller or CE, as the case may be, has good and
         marketable title to, or in case of leased Real Property or personal
         property, has valid leasehold interests in the CE Facility and the

         or acquired after the date of the Opening Statement and owned or leased

                  Intellectual Property; and

                  value of such asset of CE or the CE Facility, or materially
                  interfere with any present or intended use of such asset of CE
                  or the CE Facility (clauses (i)-(v) of this Section B.09(c)
                  are, collectively, the "Permitted Liens").

                  (d) Except as set forth on Schedule B.09 of the Disclosure
         Schedule, the material plants, buildings, structures and equipment
         included in the assets of CE and the CE Facility have no material
         defects, are in good operating condition and repair and have been
         reasonably maintained consistent with standards generally followed in
         the industry (giving due account to the age and length of use of same,
         ordinary wear an tear excepted), are adequate and suitable for their

         structures, are structurally sound.

         and electrical connections, fire protection, drainage and other public
         utilities, in each case as is necessary for the conduct of the Business
         as it has heretofore been conducted. None of the structures on the Real
         Property encroaches upon real property of another Person, and no
         structure of any other Person substantially encroaches upon any Real
         Property.

         B.10. NO UNDISCLOSED MATERIAL LIABILITIES. There are no liabilities of
the Business of any kind whatsoever, whether accrued, contingent, absolute,

                  borrowed money or the deferred purchase price of property (in
                  either case, whether incurred, assumed, guaranteed or secured
                  by any asset), except any such agreement with an aggregate
                  outstanding principal amount not exceeding $100,000 and which
                  may be prepaid on not more than 60 days notice without the
                  payment of any penalty;

                           (viii) any agency, dealer, sales representative,
                  marketing or other similar agreement; or

                           (ix) any agreement that limits the freedom of CE to
                  compete in any line of business or with any Person or in any
                  area or to own, operate, sell, transfer, pledge or otherwise
                  dispose of or encumber any asset of CE, the CE Facility or
                  which would so limit the freedom of the Purchaser after the
                  Closing Date.

                  (b) Except as set forth in Schedule B.12 of the Disclosure
         Schedule, each Contract disclosed in Schedule B.12 of the Disclosure
         Schedule or required to be disclosed pursuant to this Section is a
         valid and binding agreement of Seller or CE and is in full force and
         effect (except as limited by applicable bankruptcy, insolvency,
         reorganization, moratorium or other similar laws now or hereafter in
         effect relating to or affecting creditors' rights generally, including
         the effect of statutory and other laws regarding fraudulent conveyances
         and preferential transfers, and subject to the limitations imposed by
         general equitable principles regardless of whether such enforceability
         is considered in a proceeding at law or in equity), and none of the
         Seller or CE or, to the knowledge of the Seller, any other party
         thereto is in default or breach under the terms of any such contract,
         and, to the knowledge of Seller, no event or circumstance has occurred
         that, with notice or lapse of time or both, would constitute any event
         of default thereunder, except for defaults, breaches, events or
         circumstances that could reasonably be expected to have a Material
         Adverse Effect on the Business.

         B.13. LICENSES AND PERMITS. Schedule B.13 of the Disclosure Schedule
accurately lists and correctly describes each material license, franchise,
permit, certificate, approval or other similar authorization affecting, or
relating in any way to, the CE Facility or the Business and in effect on the
date of this Agreement (the "Permits"). Except as set forth in Schedule B.13 of
the Disclosure Schedule, (i) the Permits are valid and in full force and effect,
(ii) neither Seller nor CE is in default, and no condition exists that with
notice or lapse of time or both would constitute a default, under the Permits
and (iii) none of the Permits will, assuming compliance with the matters
referred to in Section B.05 prior to the Closing Date, be terminated or impaired
or become terminable, in whole or in part, as a result of the transactions
contemplated hereby.

         B.14. FINDERS' FEES. Except for J.P. Morgan Securities Inc., whose fees
or commissions and expenses are obligations of the Seller, there is no
investment banker, broker, finder or other intermediary that has been retained
by or is authorized to act on behalf of the Seller who might be entitled to any
fee or commission upon consummation of the Contemplated Transactions.

         B.15. ENVIRONMENTAL COMPLIANCE. Except as disclosed in Schedule B.15 of
the Disclosure Schedule, CE is now and always has been in compliance with all
applicable Environmental Laws, has developed, obtained and maintained as valid
all permits, licenses and other authorizations and plans that are required under
applicable Environmental Laws, has maintained adequate reserves for
Environmental Liabilities and Remedial Actions, and has no knowledge of
conditions at the CE Facility requiring Remedial Action, investigation or notice
to any Governmental Authority, except where the failure to be in compliance, the
failure to obtain such permits, licenses and other authorizations or the failure
to maintain adequate reserves has not had and may not reasonably be expected to
have a Material Adverse Effect on CE on or after December 28, 1997. Except as
disclosed in Schedule B.15 of the Disclosure Schedule, CE is in compliance with
the terms and conditions under which the permits, licenses and other
authorizations referenced in the preceding sentence were issued or granted,
except where the failure to be in compliance has not had and may not reasonably
be expected to have a Material Adverse Effect on CE.

         B.16. COMPLIANCE WITH LAWS. Except for matters that have been settled
or otherwise resolved, neither the Seller nor CE is in violation of, and to the
knowledge of the Seller and CE, neither the Seller nor CE is under investigation
with respect to or has been threatened to be charged with or given notice of any
violation of, any Applicable Law (other than Environmental Laws) relating to the
assets of CE, the CE Facility or the conduct of the Business, except for
violations that have not had and could not reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect.

         B.17. INTELLECTUAL PROPERTY. With respect to Intellectual Property
Rights owned by CE, except as set forth in Schedule B.17 of the Disclosure
Schedule, to the knowledge of the Seller:

                  (i) CE owns, free and clear of all Liens other than Permitted
         Liens, and subject to any licenses granted by CE prior to the Closing
         Date, all right, title and interest in such Intellectual Property
         Rights, and the use of such Intellectual Property Rights in connection
         with the operation of the Business as heretofore conducted does not
         conflict with, infringe upon or violate any patent, patent license,
         patent application, trademark, tradename, trademark or tradename
         registration, copyright, copyright registration, service mark, service
         name, brand mark or brand name or any pending application relating
         thereto, or any trade secret, know-how, programs or processes of any
         third Person, firm or corporation, except for conflicts, infringements
         or violations that have not had and may not reasonably be expected to
         have a Material Adverse Effect on the Business; and

                  (ii) CE has the right to use all inventions, processes,
         computer programs, know-how, formulae, trade secrets, patents, chip
         design, mask works, trademarks, tradenames, service marks, service
         names, brandnames, copyrights and other Intellectual Property Rights
         which are used by the Business and which are necessary for the
         continued operation of the Business in substantially the same manner as
         its operations have heretofore been conducted, except where the failure
         to have any such right has not had, and may not reasonably be expected
         to have, a Material Adverse Effect on the Business.

                                       B-7

         B.18. EMPLOYEES. Schedule B.18 of the Disclosure Schedule sets forth a
true and complete list of the names and titles of all employees of the Business
whose annual base salary exceeds $100,000.

         B.19. EMPLOYEE BENEFITS. Except as set forth in Schedule B.19 of the
Disclosure Schedule:

                  (i) Schedule B.19 of the Disclosure Schedule contains a true
         and complete list of each Employee Plan and each material Benefit
         Arrangement that currently covers any CE Employee and indicates which
         of such plans, if any, cover CE Employees exclusively. The Seller has
         made available to the Purchaser a true and complete copy of the most
         recent version of each Employee Plan and the current summary plan
         description for each Employee Plan and a description of each material
         Benefit Arrangement.

                  (ii) No CE Employee Plan is a multiemployer plan (as defined
         in Section 3(37) of ERISA). Neither the Seller nor any of the Seller's
         Affiliates has incurred any liability under Title IV of ERISA arising
         in connection with the termination of any plan covered or previously
         covered by Title IV of ERISA that could reasonably be expected to
         become, after the Closing Date, an obligation of the Purchaser, CE or
         any of their Affiliates.

                  (iii) Each Employee Plan that is intended to be qualified
         under Section 401(a) of the Code has received a determination letter
         from the IRS that it is so qualified and the Seller has no knowledge of
         any reason why such determination letter would be revoked. Each CE
         Employee Plan has been maintained in substantial compliance with its
         material terms and with the material requirements prescribed by any and
         all statutes, orders, rules and regulations, including but not limited
         to ERISA and the Code, which are applicable to such plan.

                  (iv) CE is not a party to, and has not in the past 10 years
         been a party to, any collective bargaining agreement under which the
         Seller or any of its Affiliates (including CE) have any existing or
         contingent liabilities or obligations.

                  (v) Except as disclosed in writing to the Purchaser prior to
         the date hereof, there has been no amendment by the Seller or any of
         its Affiliates relating to any CE Employee Plan that would increase the
         expense of maintaining such plan, or any CE Benefit Arrangement that
         would increase materially the expense of maintaining such arrangement,
         above the level of the expense incurred in respect thereof for the most
         recent fiscal year.

                  (vi) No payments will be made by the Seller pursuant to the
         Benefit Arrangements as a result of this transaction alone or in
         connection with another event that would not be deductible by CE or the
         Purchaser pursuant to Code Sections 162(m) or 280G.

                  (vii) To the knowledge of the Seller, there is no issue with
         respect to any CE Employee Plan that is now or has been under
         examination by the Internal Revenue Service or the Department of Labor
         and no audit with respect to any CE Employee Plan by either the
         Internal Revenue Service

                                       B-8
<PAGE>
         or the Department of Labor has occurred. To the knowledge of the
         Seller, as of the date of this Agreement there are no (x) pending or
         threatened investigations by any Governmental Authority involving or
         relating to any CE Employee Plan, (y) pending or threatened claims
         (except for claims for benefits payable in the normal operations of the
         CE Employee Plans), or (z) suits or proceedings against CE or the CE
         Employee Plans asserting any rights or claims to benefits under any CE
         Employee Plans.

                  (viii) Neither CE nor the Purchaser will be required to
         provide security to any CE Employee Plan pursuant to Section 401(a)(29)
         of the Code.

                  (ix) No circumstance exists that could reasonably be expected
         to result in the imposition of any lien under Code Section 412(n) by
         reason of the failure of the Seller or its Affiliates to make timely
         installments or other payments required by Code Section 412.

                  (x) The CE Employee Plans provide the right to amend or
         terminate such CE Employee Plans.

         B.20. FINANCIAL STATEMENTS. The Seller has made available to the
Purchaser true and complete copies of the balance sheets of CE as of December
31, 1996 and 1995, and the related statements of income and cash flows for each
of the three years in the period ended December 31, 1996, including the notes
thereto and accompanied by the report of Ernst & Young LLP (collectively, the
"CE Financial Statements"). The CE Financial Statements (taken together) fairly
present (i) the financial position of CE as of the respective dates of such
balance sheets and (ii) the results of operations and changes in cash flows of
CE for the periods ended on such dates, all in conformity with GAAP applied on a
consistent basis, except as otherwise herein or therein or in the notes thereto
stated throughout the periods involved.

         B.21. PRODUCT WARRANTY CLAIMS. All existing warranty, product liability
and similar claims have been adequately accrued for or reserved against in the
Opening Statement or the CE Financial Statements, as appropriate, or will be
adequately accrued for or reserved against in the calculation of the Final Net
Working Capital Amount, and no warranty, product liability or other claims of a
similar nature are now outstanding against CE, except in each case to the extent
such warranty, product liability or similar claims could not reasonably be
expected to have a Material Adverse Effect on the Business. To the knowledge of
the Seller, except as set forth in Schedule B.21 of the Disclosure Schedule,
there are no existing or threatened claims, or any facts upon which a claim
could be based, that any product sold or leased by CE is or was defective,
defectively designed or otherwise fails or failed to meet the terms of any
product warranty, except to the extent such claim or claims could not reasonably
be expected to have a Material Adverse Effect on the Business. To the knowledge
of the Seller, except as set forth in Schedule B.21 of the Disclosure Schedule,
no claim has been asserted against CE for renegotiation or price redetermination
in any business transaction, and Seller knows of no facts upon which any such
claim could be based, except to the extent such claim or claims could not
reasonably be expected to have a Material Adverse Effect on the Business.

                 REPRESENTATION AND WARRANTIES OF THE PURCHASER

         The Purchaser hereby represents and warrants to the Seller that:

         C.01. ORGANIZATION AND EXISTENCE. The Purchaser is a corporation
validly existing and in good standing under the laws of the State of Texas and
has all corporate powers and all governmental licenses, authorizations, consents
and approvals required to carry on its business as now conducted, except where
the failure to have such licenses, authorizations, consents and approvals has
not had and may not reasonably be expected to have, a Material Adverse Effect on
the Purchaser. The Purchaser is duly qualified to do business as a foreign
corporation in each jurisdiction where the character of the property owned or
leased by it or the nature of its activities make such qualification necessary
to carry on its business as now conducted, except for those jurisdictions where
failure to be so qualified has not had, and may not reasonably be expected to
have, a Material Adverse Effect on the Purchaser.

         C.02. CORPORATE AUTHORIZATIONS. The execution, delivery and performance
by the Purchaser of this Agreement, the Supply Agreement, the Interim Services
Agreement, the CE Facility Lease and the Sanders Sublease, and the consummation
by the Purchaser of the Contemplated Transactions, are within the corporate
powers of the Purchaser and have been duly authorized by all necessary corporate
action on the part of the Purchaser. Each of this Agreement, the Supply
Agreement, the Interim Services Agreement, the CE Facility and the Sanders
Sublease constitutes or, in the case of agreements to be executed at Closing,
will constitute at the Closing a legal, valid and binding agreement of the
Purchaser, enforceable against the Purchaser in accordance with its terms (i)
except as limited by applicable bankruptcy, insolvency, reorganization,
moratorium or other similar laws now or hereafter in effect relating to or
affecting creditors' rights generally, including the effect of statutory and
other laws regarding fraudulent conveyances and preferential transfers and (ii)
subject to the limitations imposed by general equitable principles (regardless
of whether such enforceability is considered in a proceeding at law or in
equity).

         C.03. GOVERNMENTAL AUTHORIZATION. The execution, delivery and
performance by the Purchaser of this Agreement, the Supply Agreement, the
Interim Services Agreement, the CE Facility Lease and the Sanders Sublease
require no action by or in respect of, consents or approvals of, or filing with,
any Governmental Authority other than compliance with any applicable
requirements of the HSR Act.

         C.04. NON-CONTRAVENTION. The execution, delivery and performance by the
Purchaser of this Agreement, the Supply Agreement, the Interim Services
Agreement, the CE Facility Lease and the Sanders Sublease do not and will not
(i) contravene or conflict with the charter or bylaws of the Purchaser, (ii)
assuming compliance with the matter referred to in Section C.03, contravene or
conflict with or constitute a violation of any provision of any law, regulation,
judgment, injunction,

                                       C-1
<PAGE>
order or decree binding upon or applicable to the Purchaser, or (iii) constitute
a default under or give rise to any right of termination, cancellation or
acceleration of any right or obligation of the Purchaser or to a loss of any
benefit to which the Purchaser is entitled under any provision of any agreement,
contract or other instrument binding upon the Purchaser or any license,
franchise, permit or other similar authorization held by the Purchaser, except,
in the case of clauses (ii) and (iii), for any such contravention, conflict,
violation, default, termination, cancellation, acceleration or loss that would
not have a Material Adverse Effect on the Purchaser.

         C.05. FINDERS' FEES. Except for Stephens Inc., whose fees or
commissions and expenses are obligations of the Purchaser, there is no
investment banker, broker, finder or other intermediary that has been retained
by or is authorized to act on behalf of the Purchaser who might be entitled to
any fee or commission upon consummation of the Contemplated Transactions.

         C.06. LITIGATION. There is no action, suit, investigation or proceeding
pending against, or to the knowledge of the Purchaser, threatened against or
affecting, the Purchaser before any court or arbitrator or any governmental
body, agency or official which in any matter challenges or seeks to prevent,
enjoin, alter or materially delay the Contemplated Transactions.

         C.07. INSPECTIONS. The Purchaser is an informed and sophisticated
participant in the Contemplated Transactions, and has engaged such expert
advisors, experienced in the evaluation and purchase of enterprises such as the
Business, as the Purchaser deems appropriate. The Purchaser has undertaken such
investigation, and will undertake prior to Closing such further investigation
and request such additional documents and information, as it deems necessary to
enable the Purchaser to make an informed and intelligent decision with respect
to the Contemplated Transactions. The Purchaser acknowledges that the Seller has
made no representation or warranty as to the prospects, financial or otherwise,
of the Business. The Purchaser agrees that the Seller shall accept the CE Shares
and the Business as they exist on the Closing Date based upon the Purchaser's
inspection, examination and determination with respect thereto as to all
matters, and without reliance upon any express or implied representations or
warranties of any nature, whether in writing, orally or otherwise, made by or on
behalf of or imputed to the Seller, except as expressly set forth in this
Agreement.

         C.08. INVESTMENT REPRESENTATION. The Purchaser is aware that the CE
Shares are not registered under the Securities Act. The Purchaser possesses such
knowledge and experience in financial and business matters that it is capable of
evaluating the merits and risks of its investment hereunder. The Purchaser is
acquiring the CE Shares for its own account, for investment purposes only and
not with a view to the distribution thereof. The Purchaser understands that the
CE Shares may not be sold, transferred, offered for sale, pledged, hypothecated
or otherwise disposed of without registration under the Securities Act, except
pursuant to a valid exemption from registration under the Securities Act.

         C.09. FINANCING. The Purchaser has available to it cash, marketable
securities or other investments, or presently available sources of credit, to
enable it to purchase the CE Shares and

                                       C-2
<PAGE>
satisfy all of its other obligations under the terms of this Agreement, the
Supply Agreement, the Interim Services Agreement and the CE Facility Lease.

be responsible for, and shall indemnify and hold harmless the Seller from, (i)
the timely preparation and filing of all Tax Returns of CE for Post-Closing Tax
Periods, and (ii) the preparation and filing of all Tax Returns required to be
filed by CE after the Closing Date for Pre-Closing Tax Periods other than those
Tax Returns for Income Taxes described in D.03.A. The Purchaser shall pay and be
responsible for, shall indemnify and hold harmless the Seller against, and shall
be entitled to all refunds and credits of, all Taxes (together with reasonable
attorneys' fees and any legal or other expenses for investigating or defending
any actions with respect to Taxes) with respect to CE for any Post-Closing Tax
Period, except as otherwise provided in D.06.

                  D.03.D. CONTROL OF CERTAIN TAX CONTESTS BY THE SELLER. The
Seller shall have exclusive control over and responsibility to conduct any
contest for a Pre-Closing Tax Period. In any such contest, the Purchaser will
take, and will cause CE to take, such action as the Seller may by written notice
reasonably request in connection with such contest (including the payment of a
Tax preparatory to filing a claim for refund of such Tax; provided that the
Seller shall first pay the amount of such Tax to the Purchaser).

                  D.03.E. NOTICE. The Purchaser shall notify the Seller in
writing promptly upon receipt by CE of notice of any contest or assessment
relating thereto for a Pre-Closing Tax Period. The Seller shall notify the
Purchaser in writing promptly upon receipt by the Seller of notice of any
contest or assessment relating to a Post-Closing Tax Period if it affects CE.

                  D.03.F. PAYMENT OF INDEMNIFICATION. Upon payment of any Taxes
with respect to which a party is entitled to receive indemnification hereunder,
such party shall submit an invoice to the indemnifying party stating that such
Taxes have been paid and giving in reasonable detail the particulars relating
thereto. The indemnifying party shall remit payment for such Taxes promptly upon
receipt of such notice.

                  D.03.G.  ASSISTANCE AND COOPERATION.  After the Closing Date, 
each of the Seller and the Purchaser shall:

                           (a) assist (and cause its respective Affiliates and
Representatives to assist) the other party in preparing any Returns and
statements which such other party is responsible for preparing and filing;

                           (b) cooperate fully in preparing for any Tax audits
of, or disputes, contests or proceedings with, taxing authorities regarding any
Taxes;

                                       D-3
<PAGE>
                           (c) make available to the other and to any taxing
authority as reasonably requested all information, records and documents
relating to Tax liabilities that are attributable to CE and relate to or affect
periods beginning prior to the Closing Date;

                           (d) preserve all such information, records and
documents until the expiration of any applicable statues of limitations or
extensions thereof and as otherwise required by law;

                           (e) make available to the other, as reasonably
requested, personnel responsible for preparing or maintaining information,
records and documents in connection with Tax matters;

                           (f) furnish the other with copies of all
correspondence received from any taxing authority in connection with any Tax
audit or information request with respect to any such period;

                           (g) keep confidential any information obtained
pursuant to this D.03.G., except as may otherwise be necessary in connection
with the filing of returns or claims for refund or in conducting any audit or
other Tax proceeding; and

                           (h) furnish the other with adequate information which
would enable the other party to determine its entitlement to, and the amount of,
any refund or credit to which either party reasonably believes the other party
may be entitled.

                  D.03.H. TAX CHANGES. Without the prior written consent of the
Seller, neither the Purchaser nor CE, or any Affiliate of the Purchaser shall,
to the extent it may affect or relate to CE, make or change any tax election,
change any annual tax accounting period, adopt or change any method of tax
accounting, file any amended Return, enter into any closing agreement, settle
any Tax claim or assessment, surrender any right to claim a Tax refund, consent
to any extension or waiver of the limitations period applicable to any Tax claim
or assessment or take or omit to take any other action, if any such action or
omission could reasonably be expected to have the effect of increasing the
Pre-Closing Period Tax liability of CE or the Seller.

         D.04. TAX SHARING AGREEMENTS. All Tax sharing and similar agreements
(other than the provisions of this Agreement) between CE and the Seller or any
other corporation or corporations shall be terminated as of the Closing Date,
and neither the Seller nor CE shall have liability from and after the Closing
Date under any such agreement.

         D.05. SURVIVAL OF OBLIGATIONS. The obligations of the parties set forth
in this Exhibit D shall be unconditional and absolute and shall remain in effect
until the expiration of the applicable Tax statute of limitation.

         D.06. PAYMENT FOR TAX SAVINGS. In the event that with respect to any
Pre-Closing Tax Period a change in CE's or the Seller's Tax treatment of an item
occurs which results in a Final

                                       D-4
<PAGE>
Determination that causes a Tax savings for the Purchaser or CE, the Seller
shall notify the Purchaser of such change and Tax savings and the Purchaser
shall pay to the Seller within 10 days of receiving such notice, an amount equal
to the present value of the Tax savings achieved by CE or the Purchaser as a
result of such change by the Seller calculated using a discount rate equal to
the prime rate of interest published in THE WALL STREET JOURNAL, Eastern Edition
on the date of receipt of such notice. In the event of any dispute with respect
to any amount owed under this D.06, such dispute shall be settled by a mutually
selected independent public accounting firm.

         D.07. TAX RETURN PACKAGES. The Purchaser will use reasonable commercial
efforts to cause appropriate employees of CE to prepare usual and customary Tax
return packages (in the form provided to CE for the 1996 calendar year) with
respect to the Tax period beginning January 1, 1997 and ending as of the Closing
Date. The Purchaser will use reasonable commercial efforts to cause the Tax
return packages for the period beginning on January 1, 1997 and ending as of the
Closing Date to be delivered to the Seller no later than the last day of the
third calendar month succeeding the month in which the Closing occurs.

         D.08. ALLOCATION OF INCOME, DEDUCTIONS AND OTHER ITEMS. For purposes of
the Agreement, income, deductions, and other items will be allocated between the
Pre-Closing Tax Period and the Post-Closing Tax Period based on an actual
closing of the books of CE on the Closing Date.

                     EMPLOYMENT AND EMPLOYEE BENEFIT MATTERS

         E.01. EMPLOYEE BENEFITS DEFINITIONS. The following terms shall have the
following meanings:

         "Benefit Arrangement" means each employment, severance, continuation

to, as the case may be, by the Seller or any of its Affiliates (including CE)
and (iii) covers any CE Employee and/or CE Beneficiary or for which a CE
Employee would be eligible upon retirement or other termination of service.

         "CE Beneficiary" means any Person who, at Closing, is not a CE Employee
but who is the spouse, former spouse, dependent or beneficiary of a CE Employee
if that spouse, dependent or beneficiary is or may become entitled to any
coverage or benefit (whether or not contingent) provided under any Employee Plan
or Benefit Arrangement as a result of that Person's relationship to a CE
Employee.

         "CE Benefit Arrangements" means Benefit Arrangements that are
identified as CE Benefit Arrangements on Schedule B.19, other than the Special
Retention Agreements for the CE Employees listed on Schedule E.02.

         "CE Employee" means any Person who on the Closing Date is actively
employed by CE, or who, with respect to CE, is on vacation, approved illness
absence, long-term disability, authorized leave of absence (including leave
under the Family and Medical Leave Act) or military service leave of absence as
of the Closing Date.

         "CE Employee Plans" means Employee Plans that are identified as CE

defined in Section 3(3) of ERISA, which (i) is subject to any provision of
ERISA, (ii) is or has been entered into,

                                       E-1
<PAGE>
maintained, administered or contributed to by the Seller or any of its
Affiliates (including CE), and (iii) covers any CE Employee and/or CE
Beneficiary.

         "ERISA" means the Employee Retirement Income Security Act of 1974, as
amended.

         E.02. EMPLOYEES AND EMPLOYEE BENEFITS.

                  (a) Immediately following the Closing, each CE Employee shall
continue to be employed by CE in a position similar to his or her position
immediately prior to the Closing, at the same job and same salary or wage
levels, and at the same respective location as that at which such CE Employee is
employed immediately prior to the Closing. Subject to Applicable Law, CE shall
have the right to dismiss any CE Employee at any time, with or without cause,
and to change the terms of employment of any CE Employee.

                  (b) CE shall provide any notices to CE Employees that may be
required under the Worker Adjustment Retraining and Notification Act, 29 U.S.C.
ss. 2101 et seq., ("WARN") with respect to events which occur on or after the
Closing Date.

                  (c) Commencing on the Closing Date, CE shall assume all
responsibility and liability for (i) accrued but unpaid wages, bonuses, salary
and accrued vacation of CE Employees; (ii) all claims by CE Employees and CE
Beneficiaries for severance or other termination benefits based on the events
occurring after the Closing; and (iii) all claims relating to the terms and
conditions of employment, hiring, firing, supervision, occupational safety and
health, workplace, wages and hours promotion, employment practices or treatment
of CE Employees or CE Beneficiaries, arising from or relating to events on or
after the Closing Date and, if accrued for or reserved against in the
calculation of the Final Net Working Capital Amount, claims arising from or
relating to events prior to the Closing Date. Effective as of the Closing Date
and at all times thereafter, CE shall be responsible for the payment,
sponsorship, funding, operation, investment and administration of all
compensation, employee plans and benefit arrangements provided for any CE
Employees or CE Beneficiaries. Notwithstanding the foregoing, the Seller shall
remain responsible for payment of the Special Retention Agreements for the CE
Employees listed on Schedule E.02.

                  (d) The Purchaser agrees that, to the extent bonus and
incentive payments in respect of the year ended December 31, 1997 have not been
paid as of the Closing Date, it will cause CE to make such bonus and incentive
payments in accordance with the terms of the bonus and incentive plans in
existence as of the date of this Agreement.

         E.03. PLANS FOLLOWING THE CLOSING.

                  (a) Immediately following the Closing, the Purchaser shall
provide CE Employees Employee Plans and Benefit Arrangements that are
substantially equivalent to the Employee Plans and Benefit Arrangements
maintained by the Purchaser on behalf of its other employees who are employed in
comparable positions. CE Employees shall be credited for purposes of
participation, eligibility and vesting for the service credited under Benefit
Arrangements and

                                       E-2
<PAGE>
Employee Plans which are similar to Employee Plans and Benefit Arrangements
maintained by the Purchaser for CE Employees; provided however that no service
for the Seller and its Affiliates shall be required to be recognized for any
benefit accrual purposes; and provided, further, that layoff and severance shall
be identical to those provided under the Seller's Employee Plans and Benefit
Arrangements for any CE Employee terminated or laid off in the 180-day period
following the Closing.

                  (b) Effective as of the Closing Date, the Seller and its
Affiliates (other than CE) shall retain liability to provide post-retirement
medical and life insurance benefits to CE Employees and CE Beneficiaries and CE
shall have no liability or obligation to provide post-retirement life and
medical benefits to CE Employees and CE Beneficiaries. Nothing contained herein
is intended to limit or restrict the Seller's ability to amend or terminate its
or CE's post-retirement life and medical plans before, on or after the Closing.

                  (c) CE's plans that are welfare plans (as defined in Section
3(1) of ERISA) shall not contain a clause excluding coverage for preexisting
conditions of CE Employees or CE Beneficiaries (unless and only to the extent
and for the period that such pre-existing condition as of the Closing Date would
be excluded from coverage under the welfare plans of CE) and shall provide that
any expenses incurred by a CE Employee or CE Beneficiary under the Employee
Plans and Benefit Arrangements during the calendar year in which the Closing
occurs shall be taken into account under the welfare plans covering CE Employees
or CE Beneficiaries after the Closing for the purposes of deductible and
coinsurance requirements and satisfaction of maximum out-of-pocket provisions to
the same extent as if such expenses had been incurred after the Closing.

         E.04. COLLECTIVE BARGAINING AGREEMENTS. CE is not a party to, and none
of the CE Employees are covered by, collective bargaining agreements.

         E.05. 401(K) SAVINGS PLAN OBLIGATIONS.

                  (a) CE Employees currently participate in the Lockheed Martin
Corporation Salaried Savings Plan (the "Seller's Savings Plan"). The CE
Employees shall cease to be eligible to participate in, or to accrue benefits
and service credits under the Seller's Savings Plan as of the Closing Date.
Effective as of the Closing Date, the Purchaser shall designate an existing
401(k) savings plan or CE shall establish a new 401(k) savings plan (the "CE
Savings Plan") and an associated trust under which the CE Employees will be
eligible to participate, to be effective as of the Closing Date. The Purchaser
shall provide to the Seller evidence reasonably satisfactory to the Seller that
the CE Savings Plan and the associated trust have been established and that the
CE Savings Plan qualifies under the requirements of Section 401(a) of the Code,
and that the associated trust is exempt from tax under Section 501(a) of the
Code.

                  (b) To the extent permitted by the Seller's Savings Plan,
ERISA and the Code, and with respect to elective deferrals made by CE Employees
under Section 401(k) of the Code, in accordance with Treasury Regulation
1.401(k)-1(d)(4), and provided the Seller has received evidence reasonably
satisfactory to it in accordance with the preceding paragraph, the Seller shall
take or

                                       E-3
<PAGE>
cause to be taken, such action as is required to permit CE Employees to receive
a distribution of their account balances under the Seller's Savings Plan as soon
as is reasonably practicable following the Closing Date. To the extent permitted
by the Code, CE Employees shall be permitted to roll over (or, pursuant to
Section 401(a)(31) of the Code, directly transfer) distributions to the CE
Savings Plan (other than the portion of the distribution which constitutes
participant after-tax contributions, if any). The distribution or direct
transfer shall be made in cash in an amount equal to the value of the account
balances to be distributed, determined as of the close of business on the last
business day immediately preceding the distribution, except that to the extent a
participant's or beneficiary's account balance in the Seller's Savings Plan
includes one or more promissory notes evidencing a participant loan or loans,
such promissory notes shall be distributed in kind and, if applicable, directly
transferred for the participant's or beneficiary's credit under the CE Savings
Plan. For the period from the Closing Date until the distribution or direct
transfer with respect to a particular CE Employee, CE shall collect by payroll
deduction and promptly pay over to the Seller's Savings Plan all loan payments
required on participant loans made by the Seller's Savings Plan to any CE
Employee.

         E.06. OTHER EMPLOYEE PLANS AND BENEFIT ARRANGEMENTS.

                  (a) Except with respect to the Special Retention Agreements
referenced in Section E.02(c), as of the Closing Date, CE Employees and CE
Beneficiaries shall cease to accrue or enjoy benefits under any Employee Plans
and Benefit Arrangements and shall commence accrual of benefits and
participation in those compensation and employee benefit plans and benefit
arrangements maintained by CE (or the Purchaser) pursuant to Section E.03.

                  (b) With respect to any CE Employee Plan or CE Benefit
Arrangement, effective as of the Closing, the Seller shall cease to sponsor,
administer or contribute to such CE Employee Plans and CE Benefit Arrangements.
CE shall assume all obligations and liabilities (including, without limitation,
all obligations and liabilities attributable to the period prior to the Closing
and obligations with respect to individuals who are not CE Employees or CE
Beneficiaries) of the Seller and its Affiliates with respect to such CE Employee
Plans and CE Benefit Arrangements. To the extent necessary, the Seller,
effective as of the Closing, shall cause each CE Employee Plan and CE Benefit
Arrangement to be amended to provide that sponsorship and maintenance thereof
shall be transferred as of the Closing Date to CE.

         E.07. NECESSARY ACTION. CE, the Purchaser and the Seller agree to take
all action which may be necessary in order to effectuate the transactions
contemplated by this Exhibit E, including, without limitation, adopting any
necessary amendments to the Employee Plans and Benefit Arrangements and making
all filings and submissions to the appropriate governmental agencies required to
be made.

         E.08. THIRD PARTY BENEFICIARIES. No provision of this Exhibit E shall
create any third party beneficiary rights in any CE Employee or CE Beneficiary,
including, without limitation, any right to continued employment or employment
in any particular position by CE for any specified period of time after the
Closing Date.

                                       E-4
<PAGE>
         E.09. MUTUAL ASSISTANCE. At all times after the Closing Date, CE, the
Purchaser and the Seller agree to make reasonably available to each other and
each other's agents, employees, accountants and other representatives such
actuarial, financial, personnel and related information as may be requested with
respect to any CE Employee.

         E.10. INDEMNIFICATION BY CE AND THE PURCHASER. CE and the Purchaser
shall indemnify, defend and hold harmless (i) the Seller, (ii) each Affiliate of
the Seller (other than CE), (iii) each Employee Plan or Benefit Arrangement
maintained by the Seller or its Affiliates (other than CE), and (iv) the
fiduciaries of each such Employee Plan or Benefit Arrangement from and against
any and all Damages of any kind or nature, caused by, resulting from or arising
in connection with:

                  (x) the sponsorship, operation or administration on and after
         the Closing Date of, and the payment of benefits to CE Employees and CE
         Beneficiaries under the CE Employee Plans and CE Benefit Arrangements
         as well as under all employee plans and benefit arrangements
         established by CE (or the Purchaser) hereunder;

                  (y) any responsibility, obligation or liability assumed by or
         remaining with CE and described in Sections E.02, E.03, E.05 or
         E.06(b); and

                  (z) any breach of any covenant or agreement regarding employee
         benefit matters made in this Agreement.

         E.11. INDEMNIFICATION BY THE SELLER. The Seller shall indemnify, defend
and hold harmless (i) the Purchaser, (ii) CE, (iii) each Affiliate of the
Purchaser and CE, (iv) each CE Employee Plan and CE Benefit Arrangement, and (v)
the fiduciaries of each CE Employee Plan and CE Benefit Arrangement from and
against any and all Damages of any kind or nature, caused by, resulting from or
arising in connection with:

                  (x) the sponsorship, operation or administration before the
         Closing Date of, and the payment of benefits for claims incurred prior
         to the Closing to CE Employees and CE Beneficiaries under, any Benefit
         Arrangement or Employee Plan (other than a CE Employee Plan or CE
         Benefit Arrangement);

                  (y) any responsibility, obligation or liability assumed by or
         remaining with the Seller and its Affiliates (other than CE) and
         described in the last sentence of Section E.02(c) or in Section
         E.03(b).

                                                                   ATTACHMENT II

                ADDITIONAL MATTERS RELATING TO THE CALCULATION OF
                THE PROPOSED FINAL NET WORKING CAPITAL AMOUNT AND
                      THE FINAL NET WORKING CAPITAL AMOUNT

         The Proposed Final Net Working Capital Amount and the Final Net Working
Capital Amount shall be determined on a basis consistent with the manner in
which the Opening Statement was prepared as disclosed in the notes to the
Opening Statement or as otherwise set forth in this Attachment II. Consistency
of preparation shall mean that, except as otherwise set forth in this Attachment
II (including under the heading "Exceptions to GAAP in the Opening Statement"),
all principles, classifications, methods, practices, assumptions and policies
used in the preparation of the Opening Statement shall be used or applied in the
determination of the Proposed Final Net Working Capital Amount and the Final Net
Working Capital Amount. In addition, since the use of estimates is an integral
part of the preparation of financial statements generally, and was an integral
part of the preparation of the Opening Statement, and since accounting estimates
are inherently subjective, often accompanied by a range of reasonable outcomes,
except as otherwise set forth in this Attachment II, the estimates used in the
determination of the Proposed Final Net Working Capital Amount and the Final Net
Working Capital Amount shall be prepared on a basis consistent with the
estimates used in the preparation of the Opening Statement.

         Following are additional agreements and clarifications with respect to
the determination of the Proposed Final Net Working Capital Amount and the Final
Net Working Capital Amount:

         ADJUSTMENT OF RESERVES AND VALUATION ACCOUNTS. In the determination of
the Proposed Final Net Working Capital Amount and the Final Net Working Capital
Amount, except as otherwise set forth in this Attachment II, the amount of any
reserves or valuation accounts shall be determined by applying methods,
practices, classifications, assumptions, estimates, policies, factors and
underlying data consistent with those used in determining the reserves or
valuation accounts included in the Opening Statement, and there shall be no
changes made to any reserves or valuation accounts (including, without
limitation, contract reserves, purchase accounting reserves, allowances for bad
debts, inventory reserves, warranty reserves and other reserves), except to the
extent that such changes are required by changes in facts and events occurring
after December 28, 1997 and before the Closing Date.

         INVENTORY. For purposes of determining the Proposed Final Net Working
Capital Amount and the Final Net Working Capital Amount, the parties have agreed
contractually that an inventory observation as of the Closing Date, will not be
conducted. Furthermore, in the determination of the Proposed Final Net Working
Capital Amount and the Final Net Working Capital Amount, the raw materials and
finished goods inventory of CE shall be recorded at an amount equal to their net
book value as included in the Opening Statement (which was calculated on a basis
consistent with the inventory policy set forth in the notes to the CE Financial
Statements), except to the extent that

                                      II-1
<PAGE>
changes are required by normal business activities (purchases, transfers to/from
work in process or cost of sales relief resulting from shipment of products)
occurring after December 28, 1997 but before the close of business on the day
before the Closing Date, in each case calculated in accordance with the policies
and practices reflected in the Opening Statement.

         EXCLUSION OF CERTAIN RESERVES AND LIABILITIES. There shall not be
considered in the determination of the Proposed Final Net Working Capital Amount
and the Final Net Working Capital Amount any reserve or any liability to the
extent such reserve or liability (i) arises out of, results from or relates to
any action taken by the Purchaser, including but not limited to any actions
taken in connection with the Contemplated Transactions, (ii) arises out of,
results from or relates to any actions taken or contemplated to be taken by the
Purchaser, the Seller, CE or any of their Affiliates contemporaneously with or
subsequent to the Closing, (iii) arises out of, results from or relates to a
reserve or liability that CE will not under any circumstances be obligated to
make payment on or otherwise settle at or subsequent to the Closing, (iv)
relates to or is in respect of Taxes, or (v) is indemnified against by the
Seller.

         DUE DILIGENCE COSTS. There shall be no amount accrued or reserved for
in connection with the determination of the Proposed Final Net Working Capital
Amount and the Final Net Working Capital Amount for any obligations or
liabilities incurred in connection with the Purchaser's due diligence efforts in
connection with the Contemplated Transactions, including without limitation any
fees and expenses of the counsel, independent accountants or other agents,
advisors or consultants of the Purchaser.

         CERTAIN SHARED EXPENSES. There shall not be considered in the
determination of the Proposed Final Net Working Capital Amount and the Final Net
Working Capital Amount any reserve or any liability to the extent such reserve
or liability relates to fees or expenses that, in accordance with the Agreement,
are to be shared by the Seller and the Purchaser including, without limitation,
the fees and expenses contemplated by Section 2.03(d) and Section 13.03 of the
Agreement.

         GOING CONCERN. For purposes of determining the Proposed Final Net
Working Capital Amount and the Final Net Working Capital Amount, CE and the
businesses conducted and to be conducted by CE, will be considered a "going
concern" and all of the assets owned by CE shall be deemed to be actively used
in the business of CE and not held for sale or disposal.

         CALCULATION OF NET WORKING CAPITAL. Net Working Capital shall be
calculated by subtracting current liabilities from current assets based on the
general ledger accounts maintained by CE and included in the Opening Statement.

         EXCEPTIONS TO GAAP IN THE OPENING STATEMENT. The following represent
items which are or may be considered deviations from GAAP in the Opening
Statement:

         o Comparative amounts are not presented.

                                      II-2

         o While certain explanatory footnotes are presented, such footnotes do
not represent the full complement of disclosures required by GAAP.

         o No provision for federal, state or local current or deferred Tax
assets/liabilities has been reflected in the Opening Statement.

         o No liability for workers' compensation or provision for pension or
retirement (including supplemental pension or retirement plans)
assets/liabilities or other post employment benefits or restructuring
liabilities has been reflected in the Opening Statement.

         o No stockholders' equity is reflected in the Opening Statement.

         o No liabilities for self-insurance for auto, casualty, etc. are
included in the Opening Statement.

         o No liabilities for incurred but not reported medical claims are
included in the Opening Statement.

         o No Environmental Liabilities are included in the Opening Statement.

         o No interest liability is provided for on intercompany loans in the
Opening Statement.

                                SUPPLY AGREEMENT

         This Supply Agreement is entered into as of the ____ day of ________
1998, by and between Lockheed Martin Corporation, a Maryland corporation
("Lockheed Martin"), and Benchmark Electronics, Inc., a Texas corporation
("Benchmark").

                              W I T N E S S E T H:

         WHEREAS, Lockheed Martin and Benchmark have entered into a Purchase
Agreement dated as of January 22, 1998 (as amended from time to time, the
"Agreement"); and

         WHEREAS, the Agreement contemplates, among other things, that Lockheed
Martin will sell all of the outstanding shares of capital stock of Lockheed
Commercial Electronics Company, a Delaware corporation ("CE"), to Benchmark upon
the terms and subject to the conditions set forth in the Agreement;

         WHEREAS, Lockheed Martin and certain of its Subsidiaries have existing
relationships with CE pursuant to which Lockheed Martin and those Subsidiaries
from time to time purchase materials and products from Benchmark;

         WHEREAS, Benchmark desires to continue to supply certain materials and
products to Lockheed Martin and its Subsidiaries from time to time following the
closing of the Contemplated Transactions;

         WHEREAS, Lockheed Martin and certain of its Subsidiaries will continue,
in the ordinary course of their business, to have a need for materials and
products of the type previously purchased from Benchmark; and

         WHEREAS, Section 10.01 of the Agreement contemplates that Lockheed
Martin and Benchmark will enter into a supply agreement on the terms and subject
to the conditions set forth in this Supply Agreement;

         NOW THEREFORE, in consideration of the foregoing and of the mutual
covenants and agreements of the parties contained herein, Lockheed Martin and
Benchmark agree as follows:

          1. Capitalized terms used but not defined in this Supply Agreement
shall have the meanings ascribed to them in the Agreement.

                                      III-1
<PAGE>
          2. Lockheed Martin covenants and agrees that in the event its Sanders
Business Unit ("Sanders"), in the ordinary course of its business, needs
materials or products of a type currently being purchased by Sanders from CE,
Lockheed Martin will give CE an opportunity to submit a proposal to supply such
materials or products. Lockheed Martin will consider in good faith any proposal
submitted by CE and in evaluating the proposal will consider, among other
relevant factors, price, quality, service levels, workmanship, manufacturing
controls, security or confidentiality requirements, timeliness, single or
multiple sourcing needs, prior relationships with suppliers and relationships
between Sanders' customers and CE or other suppliers. Notwithstanding the
foregoing, however, Sanders' decision to purchase materials or products from CE
shall be at the sole and absolute discretion of Lockheed Martin and Sanders.

          3. Lockheed Martin covenants and agrees that it will advise its
business units (other than Sanders) and its wholly owned Subsidiaries of the
materials and products manufactured by CE and will encourage such business units
and wholly owned Subsidiaries to consider purchasing materials and products from
CE. Lockheed Martin agrees to assist CE in its efforts to market materials and
products to business units (other than Sanders) and wholly owned Subsidiaries of
Lockheed Martin by making introductions of appropriate personnel to CE. In the
event CE desires to seek assistance from Lockheed Martin in marketing its
materials and products in accordance with the preceding sentence, CE agrees to
coordinate its efforts with the Vice President of Operations of Lockheed
Martin's Electronics Sector.

          4. This Supply Agreement, unless earlier terminated or extended in
writing signed by Lockheed Martin and Benchmark, shall terminate at the close of
business on December 31, 2000.

          5. Lockheed Martin and Benchmark agree that, if any provision of this
Supply Agreement shall be adjudicated to be invalid or unenforceable, such
provision shall be deemed deleted herefrom with respect, but only with respect,
to the operation of such provision in the particular jurisdiction in which the
adjudication was made. To the extent any such provisions may be made valid and
enforceable in such jurisdiction by limitations on the scope of the provision,
Lockheed Martin and Benchmark agree that such provision instead shall be deemed
limited to the extent, but only to the extent, necessary to make the provision
enforceable to the fullest extent permissible under the laws and public policies
in such jurisdiction.

          6. All notices, requests and other communications to any party
hereunder shall be in writing (including telecopy or similar writing) and shall

                           INTERIM SERVICES AGREEMENT

         This Interim Services Agreement (this "Agreement") is entered into as
of the ____ day of ___________ 1998, by and between Lockheed Martin Corporation,
a Maryland corporation ("Lockheed Martin"), and Benchmark Electronics, Inc., a
Texas corporation ("Benchmark").

                              W I T N E S S E T H:

         WHEREAS, Lockheed Martin and Benchmark have entered into a Purchase
Agreement dated as of January 22, 1998 (the "Purchase Agreement"), pursuant to
which Lockheed Martin has agreed to sell, and Benchmark has agreed to buy, all
of the issued and outstanding shares of capital stock of Lockheed Commercial

         WHEREAS, pursuant to Section 2.04(iii) of the Purchase Agreement,
Lockheed Martin has agreed to provide to CE certain services of a type provided
by Lockheed Martin and its Affiliates as of the date of the Purchase Agreement,
at costs consistent with past practices; and

         WHEREAS, Lockheed Martin and Benchmark desire to enter into this
Agreement to give effect to the provisions of Section 2.04(iii) of the Purchase
Agreement;

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
of the parties contained herein, the parties agree as follows:

         1. DEFINITIONS. Capitalized terms used in this Agreement but not
defined herein shall have the meanings given to them in the Purchase Agreement.

         2. SERVICES PROVIDED. During the term of this Agreement, Lockheed
Martin shall provide to CE, or at its option shall cause one or more of its
Affiliates to provide to CE, those services (the "Services") described in
Exhibit A to this Agreement that CE requests to be performed from time to time.

         3. CONSIDERATION. Benchmark shall pay to Lockheed Martin, or shall
cause CE to pay to Lockheed Martin, in consideration for the Services provided
hereunder, amounts determined on the basis of the fees referenced in Exhibit A
to this Agreement. In addition, Benchmark shall pay to Lockheed Martin, or shall
cause CE to pay to Lockheed Martin, such amounts as may be necessary to
reimburse Lockheed Martin for any reasonable out-of-pocket expenses incurred by
Lockheed Martin or its Affiliates in performing the Services. Lockheed Martin
shall invoice Benchmark for the Services provided hereunder on a monthly basis
and Benchmark shall pay, or

                                      IV-1
<PAGE>
cause CE to pay, the amount of such invoice in immediately available funds
within 15 days of the date thereof.

         4. INFORMATION TO BE PROVIDED TO LOCKHEED MARTIN. Where input or other
information has been provided by CE to Lockheed Martin or its Affiliates in the
past in connection with the provision of a Service, CE shall provide Lockheed
Martin or any Affiliate designated by Lockheed Martin with information in the
same general format and level of detail and in accordance with the same schedule
followed previously by CE in furnishing such information to Lockheed Martin or
its Affiliates.

         5. PERFORMANCE STANDARD; CONFIDENTIALITY. Nothing in this Agreement
shall require or be interpreted to require Lockheed Martin to provide a Service
to CE beyond the scope and content of such Service as provided by Lockheed
Martin to CE immediately prior to the date of this Agreement. Lockheed Martin
will perform, or cause its Affiliates to perform, each Service in the same
general manner that the Service was performed for CE immediately prior to the
date of this Agreement. Lockheed Martin will handle, and will cause its
Affiliates to handle, all information disclosed to it or them by CE that CE
identifies as proprietary and confidential in the same general manner as
Lockheed Martin handles its own information that it considers proprietary and
confidential.

         6. FORCE MAJEURE; REDUCTION OF SERVICES. Neither party shall be liable
for any loss or damage whatsoever arising out of any delay or failure in the
performance of its obligations pursuant to this Agreement to the extent such
delay or failure results from events beyond the control of that party, including
but not limited to acts of God, acts or regulations of any Governmental
Authority, war, accident, fire, flood, strikes, industrial disputes or shortages
of fuel, nor shall any party be entitled to terminate this Agreement in respect
of any such delay or failure resulting from any such event.

         7. DISPUTE RESOLUTION. In the event of any dispute between Lockheed
Martin and Benchmark with respect to the provision of any Service pursuant to
this Agreement, each of Lockheed Martin and Benchmark shall designate an
employee as its representative to attempt to resolve the dispute and each such
representative will use reasonable commercial efforts to resolve the dispute
promptly. If the individuals designated by Lockheed Martin and Benchmark are
unable to resolve the dispute promptly, the dispute will be submitted to a
member of senior management of each party. Such members of senior management
will meet in person or by telephone conference at least once in the 10-day
period following the submission of the dispute to them and will use reasonable
commercial efforts to resolve the dispute promptly. If such members of senior
management are unable to resolve the dispute within 15 days of the submission of
the dispute to them, the parties may exercise any rights or remedies available
to them in the Purchase Agreement or otherwise.

         8. LIMITED LIABILITY. Lockheed Martin and its Affiliates shall not be
liable, whether in negligence, breach of contract or otherwise, for any Damages
suffered or incurred by CE, Benchmark or a related Person arising out of or in
connection with the rendering of a Service or any

                                      IV-2
<PAGE>
failure to provide a Service, except to the extent that such Damages are caused
by the willful misconduct or gross negligence of Lockheed Martin or any of its
Affiliates. In no event shall Lockheed Martin or any of its Affiliates be liable
for special, incidental or consequential losses, Damages or expenses, including,
without limitation, loss of profits.

         9. TERM AND TERMINATION.

                                CE FACILITY LEASE

         This Lease Agreement (this "Lease") is made this ____ day of _________
1998, by and between Lockheed Martin Corporation, a Maryland corporation
("Landlord"), and Benchmark Electronics, Inc., a Texas corporation ("Tenant").


                              W I T N E S S E T H:

         WHEREAS, Landlord is the owner of the real property and an office
building consisting of approximately 250,000 square feet, located within the
Pope Technical Park in Hillsborough County, New Hampshire, commonly known as
Building #2, 65 River Road, Hudson, New Hampshire 03051 (the "Premises"), a map
of which is attached hereto as Exhibit A;

         WHEREAS, pursuant to the terms of the Purchase Agreement between
Landlord and Tenant dated as of January 22, 1998 (together with all Exhibits,
Schedules and Attachments thereto, the "Purchase Agreement"), Tenant has agreed
to lease the Premises from Landlord on the terms and conditions set forth in
this Lease; and

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
of the parties contained herein and contained in the Purchase Agreement, the
parties agree as follows:

                                    ARTICLE I
                                      TERM

         Section 1.01 TERM. The term (the "Prime Term") of this Lease shall
commence on the date hereof (the "Commencement Date") and shall continue for a
period of two years thereafter (the "Expiration Date").

         Section 1.02 ADDITIONAL TERM. In the event that Tenant shall desire to
extend this Lease at the end of the Prime Term, Tenant shall be permitted to
extend this Lease for one additional term for a period of up to four years
following the expiration of the Prime Term (the "Additional Term"). Tenant shall
provide Landlord written notice of the intent to lease the Premises for the
Additional Term at least 90 days before the expiration of the Prime Term. Upon
receipt of such written notice by Landlord, Landlord and Tenant shall negotiate
in good faith a lease for the Premises for the Additional Term on terms and
conditions consistent with the general market for the lease of commercial
facilities of the type, location and size of the Premises at that time (the
"General Market Rate"). Notwithstanding the foregoing, in the event that despite
such good faith negotiations

                                       V-1
<PAGE>
Landlord and Tenant are unable to agree on the General Market Rate for the
Additional Term, the General Market Rate shall be determined in accordance with
the provisions of Section 1.03 below.

         Section 1.03. APPRAISAL.

         (a) In the event that Landlord and Tenant cannot agree on the General
Market Rate within 60 days of the Expiration Date, then either party may invoke
its right to appraisal as set forth in this Section 1.03.

         (b) To invoke its right to appraisal, the invoking party (the "Invoking
Party") shall send written notice to the other party (the "Non-Invoking Party")
stating that it is invoking its right to appraisal and naming an appraiser with
substantial experience in commercial real estate matters in the general area in
which the CE Facility is located, who shall be a member of the Appraisal
Institute or some other comparable organization. Within 10 days after such
notice, the Non-Invoking Party shall name an appraiser who is also so qualified
and shall provide the Invoking Party with written notice of the same. Within 10
days thereafter, the two appraisers so selected (the "First Appraisers") shall
select a third appraiser (the "Outside Appraiser").

         (c) The appraisers (the First Appraisers and the Outside Appraiser)
shall attempt to determine the General Market Rate for the Premises. In making
such determination, the appraisers shall take into account that the Additional
Rent set forth in Section 3.02 of this Lease shall continue without
interruption. In the event that the First Appraisers are unable to determine a
single General Market Rate within 20 days after the date the Outside Appraiser
was selected, each of the First Appraisers shall set his or her own General
Market Rate. In the event that the General Market Rate determined by either of
the First Appraisers is within 10% (a "Close Appraisal") of the General Market
Rate established by the Outside Appraiser (the "Outside Appraisal"), the average
of the Close Appraisal or the Close Appraisals, as the case may be, and the
Outside Appraisal shall be the General Market Rate. In the event that neither
appraisal by the First Appraisers is a Close Appraisal, the General Market Rate
shall be (i) the Outside Appraisal if it falls between the other two appraisals,
(ii) the average of the Outside Appraisal and the lower of the other two
appraisals if the Outside Appraisal is lower than both of the other two
appraisals, and (iii) the average of the Outside Appraisal and the higher of the
other two appraisals if the Outside Appraisal is higher than both of the other
two appraisals. The General Market Rate so determined shall be conclusive and
binding upon the parties.

         (d) Each party shall bear all of the costs and expenses of the
appraiser selected by it and the parties shall share equally the costs of the
Outside Appraiser.

                                   ARTICLE II
                                  THE PREMISES

         Section 2.01 USE OF PREMISES. Tenant may use and occupy the Premises
during the term of this Lease for offices or light manufacturing and for no
other purposes except with the prior written consent of Landlord, provided that
any such use of the Premises shall at all times comply in all material respects
with all applicable laws and regulations, including zoning and land use laws and
regulations.

         Section 2.02 ACCESS, UTILITIES, AND PARKING. Landlord shall provide
Tenant with adequate rights (i) of ingress and egress from a publicly dedicated
road to the Premises and (ii) to public utilities in order to operate the
Premises in the manner currently being utilized. Additionally, Tenant shall be
entitled to the use of the parking lots located within the Premises sufficient
to accommodate (i) those employees that work for Lockheed Commercial Electronics
Company immediately prior to the Commencement Date and (ii) a reasonable number
of additional employees that may be employed by Tenant at the Premises in the
future.

         Section 2.03 SERVICES PROVIDED BY LANDLORD. Landlord shall provide
Tenant electric power, water, sewer, fire protection (consisting only of
sprinklers, fire extinguishers and smoke detectors), outside maintenance
services (including plowing for the roads and parking lots of the Premises) for
the Premises, in the manner that these services have been supplied to Lockheed
Commercial Electronics Company by Landlord prior to the execution of this Lease.
Tenant shall reimburse Landlord for expenses incurred in providing these
services pursuant to the terms of Section 3.02.

         Section 2.04 SERVICES NOT PROVIDED BY LANDLORD. Tenant, at its own
expense, shall be responsible for plant engineering services (including, but not
limited to, procuring heating and air conditioning maintenance and repair,
ordinary interior repair, maintenance and security for the Premises), janitorial
services, trash removal and interior window washing for the Premises.

                                   ARTICLE III
                                      RENT

         Section 3.01 BASE RENT. Tenant shall pay Landlord $382,000 per year as
rent for the Premises during the Prime Term in equal, consecutive, monthly
installments of $31,834 (the "Prime Term Rent"). The first monthly payment of
the Prime Term Rent shall be due and payable on the Commencement Date. Each
subsequent payment of the Prime Term Rent shall be due and payable on the same
calendar day of each month for the term of this Lease. In the event any such
Prime Term Rent shall not have been paid by the close of business on the fifth
calendar day following the due date for such Prime Term Rent, Tenant shall pay
to Landlord a late fee equal to 5% of the overdue amount.

         Section 3.02 ADDITIONAL RENT. Tenant shall pay as additional rent the
costs associated with real property taxes, casualty and liability insurance
policies, and the services provided by Landlord

                                       V-3
<PAGE>
pursuant to Section 2.03 for the Premises (the "Additional Rent"). The
Additional Rent shall be pro rated based on Tenant's percentage occupancy of the
Premises. Tenant acknowledges that for the purposes of this Lease, Tenant shall
be deemed to occupy 74% of the Premises for so long as a portion of the Premises
is subleased pursuant to that certain sublease between Tenant (as Sublessor) and
Sanders, a Lockheed Martin Company ("Sanders") and a division of Landlord (as
Sublessee) dated of even date herewith (the "Sublease"). If at any time during
the term of this Lease Sanders ceases to occupy a portion of the Premises
pursuant to the Sublease, then Tenant shall be deemed to occupy 100% of the
Premises for the purposes of calculating the Additional Rent pursuant to this
Section 3.02. Notwithstanding any provision of this Section 3.02 to the
contrary, Tenant shall also pay as Additional Rent 89% of the cost of electric
power for the Premises during the term of this Lease on the condition that
Sanders occupies a portion of the Premises under the Sublease. In the event
Sanders does not occupy a portion of the Premises, pursuant to the Sublease, at
any time during the term of this Lease, then Tenant shall pay 100% of the cost
of electric power for the Premises. The provisions of the preceding sentence
shall be altered by agreement of the parties, if accomplishing the foregoing
presents unreasonable difficulties under, or is otherwise required by,
applicable State of New Hampshire utilities laws. Any such Additional Rent shall
be due and payable within 10 days of receipt by Tenant of a written request for
payment thereof and reasonable documentation regarding such Additional Rent.


                                   ARTICLE IV
                                      SIGNS

         Section 4.01 SIGNS. Tenant shall have the right, at its expense, to
maintain within or on the exterior of the Building, or at its entrance to the
Premises, such signs, directories or marquees as shall serve to identify Tenant
and to direct guests to Tenant's place of business. Such signs, directories, or
marquees shall be subject to Landlord's approval, which shall not be
unreasonably withheld. Landlord agrees to identify Tenant prominently, at
Tenant's expense, by a sign located at the entrance to the Premises as soon as
reasonably practicable after the Commencement Date, such sign to be of a design
mutually approved by Landlord and Tenant and subject to compliance with local
zoning ordinances.

                                    ARTICLE V
                             TRANSFER AND SUBLETTING

         Section 5.01 TRANSFER AND SUBLETTING. Tenant shall not sublet, assign,
transfer, vacate or in any manner dispose of the Premises or any part thereof
for all or any part of the term of this Lease, other than pursuant to the
Sanders Sublease, without the prior written consent of Landlord. Notwithstanding
the above, Tenant may assign this Lease to Lockheed Commercial Electronics
Company its successors and assigns, without first obtaining the prior written
consent of Landlord. In the event Tenant assigns this Lease to Lockheed
Commercial Electronics Company, Tenant shall remain at all times liable for any
amounts owed to Landlord pursuant to this Lease.

                                   ARTICLE VI
                              SURRENDER OF PREMISES

         Section 6.01 SURRENDER OF PREMISES. On the Expiration Date, Tenant
shall peaceably surrender the Premises in its current condition, reasonable wear
and tear excepted, and ensure that the Premises are broom clean. Prior to the
Expiration Date, Tenant shall remove from the Premises all Hazardous Substances
(as defined in Section 13.01) used within, in, or as part of its business that
were placed in or on the Premises on or after the Closing Date. However, nothing
in this Lease shall require either Landlord or Tenant to remove asbestos
containing building materials present upon the Premises prior to the
Commencement Date. Any personal property left upon the Premises on the
Expiration Date shall be deemed to be abandoned by Tenant.

                                   ARTICLE VII
                                SALE OF PREMISES

prior written consent of Landlord. In no event shall any structural change or
any change or modification to the structure of the Premises' heating,
electrical, or plumbing services be undertaken by Tenant or an employee or agent
of Tenant without Landlord's prior written consent. Any approved alterations,
additions, or improvements, shall be done in accordance with the applicable
county, city and State laws and ordinances and building and zoning rules and
regulations. Tenant hereby expressly assumes full responsibility for all damages
and for injuries which may result to any person or property by reason of or
resulting from said alterations, additions, or improvements, and shall hold
Landlord harmless with respect thereto, except with respect to those injuries
and damages arising out of Landlord's fault or negligence. On the Expiration
Date, all alterations, additions, and improvements to the Premises shall become
the property of Landlord.

         Section 8.02 APPROVAL OF LANDLORD REQUIRED. No such alterations,
additions or improvements over $25,000 may be commenced in the Premises, until
Tenant has prepared or had prepared plans and specifications for the work and
obtained Landlord's written approval therefor.


         Section 8.03 PAYMENT BY TENANT. Tenant shall pay, when due, any and all
sums of money that may be due for any labor services, materials, supplies or
equipment alleged to have been

                                       V-5
<PAGE>
furnished or to be furnished to or for Tenant in, on, or about the Premises and
which may be secured by any mechanics, material or other liens against the
Premises or of Landlord's interest therein, and Tenant shall cause each such
lien to be fully discharged and released at the time the performance of any
obligation secured by any such lien matures or becomes due. Landlord reserves
the right at any or all times to alter the Premises or add thereto so long as it
does not have an adverse effect on Tenant's right to quiet enjoyment of the
Premises.

                                   ARTICLE IX
                                    LIABILITY

         Section 9.01 LIABILITY. Landlord in no event shall be liable for, and
Tenant shall indemnify and hold harmless Landlord from, any damage or injury to
Tenant or any agent or employee of Tenant including, without limitation,
business invitees and contract laborers, or to any person or persons coming upon
the Premises in connection with the occupancy by Tenant of the Premises, or to
any goods, chattels or other property of Tenant, or any other person or persons
which may during the term of this Lease be located in the Premises, unless
Landlord was responsible for such injury through Landlord's own negligence or
intentional act. Landlord shall not be liable for, and Tenant shall indemnify
and hold harmless Landlord from, any damage to Tenant's personal property and to
personal property of others in Tenant's possession or under Tenant's care and
control located within the Premises whether such damage is caused or contributed
to by fire, water, rain, snow, breakage of pipes, Acts of God, leakage, or in
the event that such damage is due to the fault or negligence of Tenant, its
agents or employees, business invitees, and contract laborers, unless Landlord
was responsible for such damage through Landlord's own negligence or intentional
act. Tenant shall carry insurance to cover damage by fire or other casualty to
Tenant's personal property.

                                    ARTICLE X

persons designated by Landlord have the right to enter the Premises at
reasonable hours to examine the same and to do such work as Landlord is
obligated to do under the terms of this Lease, or to do such work as Landlord
shall deem necessary for the safety or preservation of the Premises; provided
however, that the same shall not interfere unreasonably with the conduct of
Tenant's business.

         Section 10.02 QUIET ENJOYMENT. Subject to the terms of this Lease,
Landlord covenants that if Tenant pays the rent pursuant to Section 3.01 and the
Additional Rent, performs all of its obligations provided for hereunder and

termination of such ground or underlying lease prior to the expiration or

thereof) which may be instituted or undertaken in order to enforce any right or
remedy available to the holder of such instrument, (ii) Tenant shall not be
named as a party defendant in any foreclosure, summary or any other action
commenced by any such ground or underlying lessor or secured party, and (iii)

enforcement action or otherwise shall be bound to Tenant, and Tenant shall be
bound to it, under all of the terms, covenants and conditions of this Lease with
the same force and effect as if such party were the original Landlord under this
Lease. Landlord covenants and agrees that it will obtain and deliver to Tenant a
Non-Disturbance Agreement in accordance with the foregoing provisions from the
then holder(s) of any mortgage, deed of trust, ground lease or other security
instrument affecting the Premises on or before the date the Premises are ready
for occupancy, failing which tenant may, at its option, terminate this Lease
whereupon any prepaid rent or other prepaid charges or deposits paid by Tenant
to Landlord shall be immediately refunded.

or to such addresses or telecopy numbers and with such other copies, as such
party may hereafter specify for the purpose of notice to the other parties. Each

         Section 18.02 EMINENT DOMAIN. If the whole or any part of the Premises
shall be taken by public authority under the power of eminent domain, then the
term of this Sublease shall cease on the part so taken from the day that
possession of that part shall be required for any purpose by said public
authority, and the Rent shall be paid up to that day, and if such portion of the
Premises are so taken as to, in Sublessee's opinion, destroy the usefulness of
the Premises for the purpose for which the Premises were leased, then, from that
day, Sublessee shall have the right either to terminate this Sublease and
declare the same null and void, or to continue in the possession of the
remainder of the same under the terms herein provided, except that the Rent
shall be reduced in proportion to the amount of the Premises taken based on the
value of the portion taken to the value of the remaining part. All damages
awarded for such taking shall belong to and be the property of Sublessor,
including such damages as shall be awarded as compensation for diminution in
value to the leasehold, provided, however, that Sublessor shall not be entitled
to any portion of the award made to Sublessee for Sublessee's furnishings or
Sublessee's business relocation expenses.

         Section 18.03 DESTRUCTION OF PREMISES. If, during the term of this
Sublease, the Premises are totally or partially destroyed from any cause,
rendering the Premises totally or partially inaccessible or unusable, Sublessor
shall restore the destruction if the restoration can be made under the existing
laws and can be completed within 120 working days after the destruction. Such
destruction shall not terminate the Sublease. During the period that the
premises are being restored

<PAGE>
Sublessee shall neither pay nor owe the Rent to Sublessor. If the restoration
cannot be made within 120 days, then within 10 days after such destruction
Sublessee or Sublessor can terminate this Sublease immediately by giving written
notice and, thereafter, neither party shall bear any further liability under
this Sublease.

         Section 18.04 ENTIRE AGREEMENT. This Sublease contains all
representations, understandings, agreements and commitments of Sublessor and
Sublessee, and any other written or oral statements of promises of any type
whatsoever shall be null and void and of no effect whatsoever in the
interpretation of this Sublease.

         Section 18.05 APPLICABLE LAW; JURISDICTION. This Sublease shall be
construed in accordance with the laws of the State of New Hampshire without
reference to the conflicts of laws principles thereof. The forum for any
disputes arising hereunder shall be a court of competent jurisdiction sitting in
the State of New Hampshire, and by executing this Lease, Landlord and Tenant
consent to such jurisdiction.

         IN WITNESS WHEREOF, the parties have caused this Sublease to be

        Section 2.1   LOANS AND COMMITMENTS.

               (a) LOANS. Subject to the terms and conditions and relying on the
representations and warranties contained herein (1) each Lender severally agrees

(each a "TERM LOAN") to the Company, and (2) on any Business Day on and after
the Closing Date, but prior to the Revolving Credit Maturity Date, each Lender
severally agrees to make revolving credit loans (each a "REVOLVING CREDIT LOAN")
to the Company. Except for in connection with a continuation or conversion
pursuant to Section 2.11, any Term Loan that is repaid or prepaid may not be
reborrowed.

               (b) TYPES OF LOANS. The Revolving Credit Loans and the Term Loans
made pursuant hereto by each Lender shall, at the option of the Company, be
either Base Rate Loans or Eurodollar Loans and may be continued or converted
pursuant to Section 2.11, provided that, except as otherwise specifically
provided herein, all Loans made pursuant to the same Borrowing shall be of the
same Type.

               (c) REVOLVING CREDIT COMMITMENTS. Each Lender's Revolving Credit
Exposure shall not exceed at any one time the amount set forth opposite such
Lender's name on Annex I under the caption "Revolving Credit Commitment" (as the
same may be reduced pursuant to Section 2.9 or otherwise from time to time
modified pursuant to Section 9.7, its "REVOLVING CREDIT COMMITMENT," and
collectively for all Lenders, the "REVOLVING CREDIT COMMITMENTS"); PROVIDED,
HOWEVER, that the Aggregate Revolving Credit Exposure at any one time
outstanding shall not exceed the Maximum Available Amount in effect at such
time; and, PROVIDED, FURTHER, the aggregate principal amount of all Revolving
Credit Loans at any one time


                                       17
<PAGE>
outstanding shall not exceed the difference between (1) the Maximum Available
Amount in effect at such time, and (2) the aggregate amount of all Letter of
Credit Liabilities at such time. There may be more than one Borrowing with
respect to Revolving Credit Loans on any day. Within the foregoing limits and
subject to the conditions set out in Article 3, the Company may obtain
Borrowings of Revolving Credit Loans, repay or prepay such Revolving Credit
Loans, and reborrow such Revolving Credit Loans.

               (d) TERM LOAN COMMITMENTS. The Term Loans made pursuant hereto by
each Lender shall not exceed in aggregate principal amount outstanding the
amount set forth opposite such Lender's name on Annex I under the caption "Term
Loan Commitment" (its "TERM LOAN COMMITMENT," and collectively for all Lenders,
the "TERM LOAN COMMITMENTS"). Any portion of each such Lender's Term Loan
Commitment not utilized on the Effective Date shall be permanently canceled. Any
Term Loans that are repaid or prepaid may not be reborrowed.

               (e) AMOUNTS OF BORROWINGS, ETC. The aggregate principal amount of
each Borrowing (1) of Eurodollar Loans shall be not less than $500,000 and shall
be in an integral multiple of $500,000, and (2) of Base Rate Loans hereunder
shall be not less than $500,000 and shall be in an integral multiple of
$500,000, except that any Borrowing of Revolving Credit Loans that are Base Rate
Loans may be in the aggregate amount of the unused Maximum Revolving Credit Loan
Amount in effect at such time. Borrowings of more than one Type may be
outstanding at the same time; PROVIDED, HOWEVER, that the Company shall not be
entitled to request any Borrowing that, if made, would result in an aggregate of
more than five (5) separate Borrowings of Eurodollar Loans being outstanding at
any one time. For purposes of the foregoing, Borrowings having different
Interest Periods, regardless of whether they commence on the same date, shall be
considered separate Borrowings.

        Section 2.2   BORROWING REQUESTS.

               (a) BORROWING REQUESTS. Whenever the Company desires to make a
Borrowing hereunder, it shall give Advance Notice in the form of a Borrowing

               (b) NOTICE BY ADMINISTRATIVE AGENT. The Administrative Agent
shall promptly give each Lender telecopy or telephonic notice (and, in the case
of telephonic notices, confirmed by telecopy or otherwise in writing) of the
proposed Borrowing, of such Lender's Applicable Percentage thereof and of the
other matters covered by the Advance Notice. The Company hereby waives the right
to dispute the Administrative Agent's record of the terms of such telephonic
notice, absent manifest error.

        Section 2.3   LETTERS OF CREDIT.

               (a) ISSUANCE OF LETTERS OF CREDIT. Subject to the terms and
conditions hereof, the Company shall have the right, in addition to Revolving
Credit Loans provided for in Section 2.1, to utilize the Revolving Credit
Commitments from time to time prior to the Revolving Credit Maturity Date by
obtaining the issuance of either Documentary Letters of Credit or Standby
Letters of Credit for the account of the Company by the Issuing Bank if the
Company shall so request in the notice referred to in Section 2.3(b)(1) (such
letters of credit being collectively referred to as the "LETTERS OF CREDIT");
PROVIDED, HOWEVER, that the Aggregate Revolving Credit Exposure at any one time
outstanding shall not exceed the Maximum Available Amount in effect at such time
and the aggregate of all Letter of Credit Liabilities at any one time
outstanding shall not exceed $5,000,000. The Letters of Credit shall be
denominated in Dollars and


                                       18
<PAGE>
may be issued to support the obligations of the Company or any of its
Subsidiaries. Upon the date of the issuance of a Letter of Credit, the Issuing
Bank shall be deemed, without further action by any party hereto, to have sold
to each Lender, and each Lender shall be deemed, without further action by any
party hereto, to have purchased from the Issuing Bank, a participation, to the
extent of such Lender's Revolving Credit Percentage, in such Letter of Credit
and the related Letter of Credit Liabilities. No Letter of Credit issued
pursuant to this Agreement shall have an expiry date beyond the earlier of one
year after the date of issuance or five days prior to the Revolving Credit
Maturity Date. Any Letter of Credit may give the beneficiary thereof either the
right to draw upon the Letter of Credit upon its expiry date or the right to
automatically extend the expiry date thereof for periods of up to one year per
extension; PROVIDED that no such extension shall extend the expiry date beyond
five days prior to the Revolving Credit Maturity Date.

               (b) ADDITIONAL LETTER OF CREDIT PROVISIONS. The following
additional provisions shall apply to each Letter of Credit:

                      (1) The Company shall give the Administrative Agent and
        the Issuing Bank at least three Business Days' prior notice (effective
        upon receipt), or in each case, such shorter period as may be agreed to
        by the Administrative Agent and the Issuing Bank, specifying the date
        such Letter of Credit is to be issued (which shall be a Business Day)
        and describing: (A) the face amount of the Letter of Credit, (B) the
        expiration date of the Letter of Credit, (C) the name and address of the
        beneficiary, (D) information concerning the transaction proposed to be
        supported by such Letter of Credit as the Administrative Agent or the
        Issuing Bank may reasonably request, (E) such other information and
        documents relating to the Letter of Credit as the Administrative Agent
        or the Issuing Bank may reasonably request, and (F) a precise
        description of documents and the verbatim text of any certificate to be
        presented by the beneficiary, which, if presented prior to the expiry
        date of the Letter of Credit, would require the Issuing Bank to make
        payment under the Letter of Credit; PROVIDED that the Issuing Bank, in
        its reasonable judgment, may require changes in such documents and
        certificates; and PROVIDED FURTHER that the Issuing Bank shall not be
        required to issue any Letter of Credit that on its terms requires
        payment thereunder prior to the next Business Day following receipt by
        the Issuing Bank of such documents and certificates. Each such notice
        shall be accompanied by the Issuing Bank's Application and by a
        certificate executed by a Responsible Officer setting forth calculations
        evidencing availability for such Letter of Credit pursuant to Section
        2.3(b)(2) and stating that all conditions precedent to such issuance
        have been satisfied. Each Letter of Credit shall, to the extent not
        inconsistent with the express terms hereof or the applicable
        Application, be subject to the Uniform Customs and Practice for
        Documentary Credits (1993 Revision), International Chamber of Commerce
        Publication No. 500 (together with any subsequent revisions thereof
        approved by a Congress of the International Chamber of Commerce, the
        "UCP"), and shall, as to matters not governed by the UCP, be governed
        by, and construed and interpreted in accordance with, the laws of the
        State of Texas.

                      (2) No Letter of Credit may be issued if after giving
        effect thereto the Aggregate Revolving Credit Exposure would exceed the
        Maximum Available Amount. On each day during the period commencing with
        the issuance of any Letter of Credit and until such Letter of Credit
        shall have expired or have been terminated, the Revolving Credit
        Commitment of each Lender shall be deemed to be utilized for all
        purposes hereof in an amount equal to such Lender's Revolving Credit
        Percentage of the amount of the Letter of Credit Liabilities related to
        such Letter of Credit.

                      (3) Upon receipt from the beneficiary of any Letter of
        Credit of any demand for payment thereunder, the Issuing Bank shall
        promptly notify the Company and the Administrative Agent of such demand
        (provided that the failure of the Issuing Bank to give such notice shall
        not


                                       19
<PAGE>
        affect the Reimbursement Obligations of the Company hereunder) and the
        Company shall immediately, and in any event no later than 10:00 a.m.
        (Houston, Texas time) on the date of such drawing, reimburse the
        Administrative Agent for the account of the Issuing Bank for any amount
        paid by the Issuing Bank upon any drawing under any Letter of Credit,
        without presentment, demand, protest or other formalities of any kind in
        an amount, in same day funds, equal to the amount of such drawing.
        Unless prior to 10:00 a.m. (Houston, Texas time) on the date of such
        drawing, the Company shall have either notified the Issuing Bank and the
        Administrative Agent that the Company intends to reimburse the
        Administrative Agent for the account of the Issuing Bank for the amount
        of such drawing with funds other than the proceeds of Revolving Credit
        Loans or delivered to the Administrative Agent a Borrowing Request for
        Revolving Credit Loans in an amount equal to such drawing, the Company
        will be deemed to have given a Borrowing Request to the Administrative
        Agent requesting that the Lenders make Revolving Credit Loans which
        shall be Base Rate Loans on the date on which such drawing is honored in
        an amount equal to the amount of such drawing; PROVIDED THAT such Loans
        shall be subject to (A) the satisfaction of the conditions in Article 3
        and (B) the existence of Revolving Credit Loan availability pursuant to
        Section 2.1(c) hereof (after giving effect to repayment of the
        applicable Reimbursement Obligations with the proceeds of the proposed
        Revolving Credit Loans). Subject to the preceding sentence, if so
        requested by the Administrative Agent, each of the Lenders shall, on the
        date of such drawing, make such Revolving Credit Loans in an amount
        equal to such Lender's Revolving Credit Percentage of such drawing or
        the full amount of the unused Revolving Credit Loan available pursuant
        to Section 2.1(c), as applicable, the proceeds of which shall be applied
        directly by the Administrative Agent to reimburse the Issuing Bank to
        the extent of such proceeds.

                      (4) If the Company fails to reimburse the Issuing Bank as
        provided in clause (3) above for any reason, including, but not limited
        to, failure to satisfy the conditions in Article 3 or insufficient
        unused Revolving Credit Loan availability pursuant to Section 2.1(c),
        the Issuing Bank shall promptly notify the Administrative Agent and the
        Administrative Agent shall notify each Lender of the unreimbursed amount
        of such drawing and of such Lender's respective participation therein
        based on such Lender's Revolving Credit Percentage. Each Lender will pay
        to the Administrative Agent for the account of the Issuing Bank on the
        date of such notice an amount equal to such Lender's Revolving Credit
        Percentage of such unreimbursed drawing (or, if such notice is made
        after 1:00 p.m. (Houston, Texas time) on such date, on the next
        succeeding Business Day). If any Lender fails to make available to the
        Issuing Bank the amount of such Lender's participation in such Letter of
        Credit as provided in this clause (4), the Issuing Bank shall be
        entitled to recover such amount on demand from such Lender together with
        interest at the Federal Funds Effective Rate for one Business Day and
        thereafter at the Base Rate. Nothing in this clause (4) shall be deemed
        to prejudice the right of any Lender to recover from the Issuing Bank
        any amounts made available by such Lender to the Issuing Bank pursuant
        to this clause (4) if it is determined by a court of competent
        jurisdiction that the payment with respect to a Letter of Credit by the
        Issuing Bank was wrongful and such wrongful payment was the result of
        gross negligence or willful misconduct on the part of the Issuing Bank.
        The Issuing Bank shall pay to the Administrative Agent and the
        Administrative Agent to each Lender such Lender's Revolving Credit
        Percentage of all amounts received from the Company for payment, in
        whole or in part, of the Reimbursement Obligation in respect of any
        Letter of Credit, but only to the extent such Lender has made payment to
        the Issuing Bank in respect of such Letter of Credit pursuant to this
        clause (4).

                      (5) The issuance by the Issuing Bank of each Letter of
        Credit shall, in addition to the conditions precedent set forth in
        Article 3, be subject to the conditions precedent that such Letter of
        Credit shall be in the form and contain such terms as shall be
        reasonably satisfactory to the Issuing Bank, and that the Company shall
        have executed and delivered such other instruments and


                                       20
<PAGE>
        agreements relating to the Letter of Credit as the Issuing Bank shall
        have reasonably requested and that are not inconsistent with the terms
        of this Agreement including the Issuing Bank's Application therefor. In
        the event of a conflict between the terms of this Agreement and the
        terms of any Application, the terms of this Agreement shall control.

                      (6) AS BETWEEN THE COMPANY AND THE ISSUING BANK, THE
        COMPANY ASSUMES ALL RISKS OF THE ACTS AND OMISSIONS OF OR MISUSE OF THE
        LETTERS OF CREDIT ISSUED BY THE ISSUING BANK BY THE RESPECTIVE
        BENEFICIARIES OF SUCH LETTERS OF CREDIT. IN FURTHERANCE AND NOT IN
        LIMITATION OF THE FOREGOING, THE ISSUING BANK SHALL NOT BE RESPONSIBLE:
        (A) FOR THE FORM, VALIDITY, SUFFICIENCY, ACCURACY, GENUINENESS OR LEGAL
        EFFECT OF ANY DOCUMENT SUBMITTED BY ANY PERSON IN CONNECTION WITH THE
        APPLICATION FOR OR ISSUANCE OF SUCH LETTERS OF CREDIT, EVEN IF IT SHOULD
        IN FACT PROVE TO BE IN ANY OR ALL RESPECTS INVALID, INSUFFICIENT,
        INACCURATE, FRAUDULENT OR FORGED; (B) FOR THE VALIDITY OR SUFFICIENCY OF
        ANY INSTRUMENT TRANSFERRING OR ASSIGNING OR PURPORTING TO TRANSFER OR
        ASSIGN ANY SUCH LETTER OF CREDIT OR THE RIGHTS OR BENEFITS THEREUNDER OR
        PROCEEDS THEREOF, IN WHOLE OR IN PART, WHICH MAY PROVE TO BE INVALID OR
        INEFFECTIVE FOR ANY REASON; (C) FOR ERRORS, OMISSIONS, INTERRUPTIONS OR
        DELAYS IN TRANSMISSION OR DELIVERY OF ANY MESSAGES, BY MAIL, CABLE,
        TELEGRAPH, TELEX OR OTHERWISE, WHETHER OR NOT THEY ARE IN CIPHER; (D)
        FOR ERRORS IN INTERPRETATION OF TECHNICAL TERMS; (E) FOR ANY LOSS OR
        DELAY IN THE TRANSMISSION OR OTHERWISE OF ANY DOCUMENT REQUIRED IN ORDER
        TO MAKE A DRAWING UNDER ANY SUCH LETTER OF CREDIT OR OF THE PROCEEDS
        THEREOF; (F) FOR THE MISAPPLICATION BY THE BENEFICIARY OF ANY SUCH
        LETTER OF CREDIT OF THE PROCEEDS OF ANY DRAWING UNDER SUCH LETTER OF
        CREDIT; AND (G) FOR ANY CONSEQUENCES ARISING FROM CAUSES BEYOND THE
        CONTROL OF THE ISSUING BANK, INCLUDING, WITHOUT LIMITATION, THE ACTIONS
        OF ANY GOVERNMENTAL AUTHORITY. NONE OF THE ABOVE SHALL AFFECT, IMPAIR,
        OR PREVENT THE VESTING OF ANY OF THE ISSUING BANK'S RIGHTS OR POWERS
        HEREUNDER. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS
        CLAUSE (G), THE COMPANY SHALL NOT ASSUME ANY RISK, AND SHALL HAVE NO
        OBLIGATION TO INDEMNIFY THE ISSUING BANK, IN RESPECT OF ANY LIABILITY
        INCURRED BY THE ISSUING BANK ARISING PRIMARILY OUT OF THE GROSS
        NEGLIGENCE OR WILLFUL MISCONDUCT OF THE ISSUING BANK, AS DETERMINED BY A
        COURT OF COMPETENT JURISDICTION.

                      (7) The Issuing Bank will send to the Company and the
        Administrative Agent immediately upon issuance of any Letter of Credit,
        or an amendment thereto, a true and complete copy of such Letter of
        Credit, or such amendment thereto. Upon issuance of any Letter of Credit
        or an amendment thereto, the Administrative Agent shall promptly notify
        each Lender of the terms of such Letter of Credit or amendment thereto,
        and of such Lender's Revolving Credit Percentage of the amount of such
        Letter of Credit or amendment thereto, and the Administrative Agent
        shall provide to each Lender a copy of such Letter of Credit or such
        amendment thereto. Upon cancellation or termination of any Letter of
        Credit, the Issuing Bank shall promptly notify the Administrative Agent
        and the Company, and the Administrative Agent will then promptly notify
        each Lender, of such cancellation or termination.

                      (8) The obligation of the Company to reimburse the Issuing
        Bank for Reimbursement Obligations with regard to the Letters of Credit
        issued by it and the obligations of the Lenders under clause (4) shall
        be unconditional and irrevocable and shall be paid strictly in
        accordance with the terms of this Agreement and under all circumstances
        including, without limitation, the following circumstances:

                             (A)    any lack of validity or enforceability of 
                                    any Letter of Credit;


                                       21
<PAGE>
                             (B)    the existence of any claim, set-off, defense
                                    or other right that the Company may have at
                                    any time against a beneficiary or any
                                    transferee of any Letter of Credit (or any
                                    Persons for whom any such transferee may be
                                    acting), any Lender or any other Person,
                                    whether in connection with this Agreement,
                                    the transactions contemplated herein or any
                                    unrelated transaction (including any
                                    underlying transaction between the Company
                                    or one of its Subsidiaries and the

                                    was procured) other than a defense based on
                                    the gross negligence (AS OPPOSED TO ORDINARY
                                    NEGLIGENCE) or willful misconduct of the
                                    Issuing Bank, as determined by a court of
                                    competent jurisdiction;

                             (C)    any draft, demand, certificate or any other
                                    document presented under any Letter of

                                    invalid or insufficient in any respect or
                                    any statement therein is untrue or
                                    inaccurate in any respect;

                             (D)    any adverse change in the condition
                                    (financial or otherwise) of the Company;

                             (E)    any breach of this Agreement or any other

                                    Administrative Agent or any Lender (other
                                    than the Issuing Bank);

                             (F)    any other circumstance or happening
                                    whatsoever which is similar to any of the
                                    foregoing; PROVIDED that such other
                                    occurrence or happening is not the result of
                                    the gross negligence (AS OPPOSED TO ORDINARY
                                    NEGLIGENCE) or willful misconduct of the
                                    Issuing Bank, as finally judicially
                                    determined by a court of competent
                                    jurisdiction; or

                             (G)    the fact that a Default shall have occurred 
                                    and be continuing.

        Section 2.4   DISBURSEMENT OF FUNDS.

               (a) AVAILABILITY. No later than 11:00 a.m. (or, in the case of
Base Rate Loans, 1:00 p.m.) (Houston, Texas time) on the date of each Borrowing,
each Lender will make available to the Administrative Agent such Lender's
Applicable Percentage of the amount (if any) by which the principal amount of
the Borrowing requested to be made on such date by such Lender exceeds the
principal amount of Loans (if any) of such Lender maturing on such date, in
Dollars and in immediately available funds at the Payment Office. The
Administrative Agent will make available to the Company at the Payment Office
the aggregate of the amounts (if any) so made available by the Lenders by
depositing such amounts, in immediately available funds, to an account of the
Company at the Administrative Agent designated by the Company for such purpose.
To the extent that Revolving Credit Loans mature or Reimbursement Obligations
are due and owing on the date of a requested Borrowing of Revolving Credit
Loans, the Lenders shall apply the proceeds of the Revolving Credit Loans then
being made, to the extent thereof, to the repayment of such maturing Revolving
Credit Loans or Reimbursement Obligations, such Revolving Credit Loans or
Reimbursement Obligations and repayments intended to be a contemporaneous
exchange.


                                       22

               (b) FUNDS TO THE ADMINISTRATIVE AGENT. Unless the Administrative
Agent shall have been notified by any Lender prior to the date of a Borrowing
that such Lender does not intend to make available to the Administrative Agent
such Lender's Applicable Percentage of the Borrowing to be made on such date,
the Administrative Agent may assume that such Lender has made such amount
available to the Administrative Agent on such date, and the Administrative Agent
may make available to the Company a corresponding amount. If such corresponding
amount is not in fact made available to the Administrative Agent by such Lender
on the date of a Borrowing, the Administrative Agent shall be entitled to
recover such corresponding amount on demand from such Lender together with
interest at the Federal Funds Effective Rate. If such Lender does not pay such
corresponding amount forthwith upon the Administrative Agent's demand therefor,
the Administrative Agent shall promptly notify the Company, and the Company
shall immediately pay such corresponding amount to the Administrative Agent
together with interest at the rate specified for the Borrowing which includes
such amount paid. Nothing in this Section shall be deemed to relieve any Lender
from its obligation to fulfill its Commitments hereunder or to prejudice any
rights which the Company may have against any Lender as a result of any default
by such Lender hereunder.

               (c) LENDERS' RESPONSIBILITIES. No Lender shall be responsible for
any default by any other Lender in its obligation to make Loans hereunder, and
each Lender shall be obligated to make only such Loans provided to be made by it
hereunder, regardless of the failure of any other Lender to fulfill its
Commitment hereunder.

        Section 2.5   NOTES AND AMORTIZATION.

               (a) REVOLVING CREDIT NOTES. The Company's obligation to pay the
principal of, and interest on, the Revolving Credit Loans made by each Lender
shall be further evidenced by the Company's issuance, execution and delivery of
a Revolving Credit Note payable to the order of each such Lender in the amount
of such Lender's Revolving Credit Commitment and shall be dated as of the date
of issuance of such Revolving Credit Note. The principal amount of each
Revolving Credit Note shall be payable on or before the Revolving Credit
Maturity Date.

               (b) TERM NOTES AND AMORTIZATION. The Company's obligation to pay
the principal of, and interest on, the Term Loans maintained outstanding by each
Lender shall be further evidenced by the Company's issuance, execution and
delivery of a Term Note payable to the order of each such Lender in the amount
of such Lender's Term Loan Commitment (if issued prior to the Closing Date) or
in the principal amount of such Lender's Term Loans (if issued after the Closing
Date), and dated as of the date of issuance of such Term Note. The aggregate
principal amount of the Term Notes applicable to the aggregate Term Loans of all
Lenders shall be payable in quarterly installments of the amounts set forth
below:

        Section 2.6   INTEREST.  In all cases subject to Section 9.13:

               (a) BASE RATE LOANS. Subject to Section 2.6(c), the Company
agrees to pay interest in respect of the unpaid principal amount of each Base
Rate Loan from the date thereof until payment in full thereof at a rate per
annum which shall be, for any day, equal to the sum of the Applicable Margin
plus the Base Rate in effect on such day, but in no event to exceed the Highest
Lawful Rate. The term "BASE RATE" shall mean, for any day, the highest of (1)
the Prime Rate in effect on such day, and (2) one-half of one percent (1/2%)
plus the Federal Funds Effective Rate in effect for such day (rounded upwards,
if necessary, to the nearest 1/16th of 1%), but in no event to exceed the
Highest Lawful Rate. For purposes of this Agreement, any change in the Base Rate
due to a change in the Federal Funds Effective Rate or the Prime Rate shall be
effective as of the opening of business on the effective date of such change in
the Federal Funds Effective Rate or the Prime Rate, as the case may be. If for
any reason the Administrative Agent shall have determined (which determination
shall be conclusive and binding, absent manifest error) that it is unable to
ascertain the Federal Funds Effective Rate for any reason, including but not
limited to the inability of the Administrative Agent to obtain sufficient bids
or publications in accordance with the terms hereof, the Base Rate shall be the
Prime Rate until the circumstances giving rise to such inability no longer
exist.

               (b) EURODOLLAR LOANS. Subject to Section 2.6(c), the Company
agrees to pay interest in respect of the unpaid principal amount of each
Eurodollar Loan from the date thereof until payment in full


                                       24
<PAGE>
thereof at a rate per annum which shall be the sum of the relevant Applicable
Margin plus the Eurodollar Rate, but in no event to exceed the Highest Lawful
Rate.

               (c) DEFAULT INTEREST. If the Company shall default in the payment
of the principal of or interest on any Loan or any other amount becoming due
hereunder or under any Financing Document, by acceleration or otherwise, the
Company shall on demand from time to time pay interest, to the extent permitted
by law, on such defaulted amount to but excluding the date of actual payment
(after as well as before judgment) at a rate per annum equal to (1) in the case
of any Eurodollar Loan, the rate that would be applicable under Section 2.6(b)
to such Eurodollar Loan, plus 2% per annum, and (2) in the case of any other
amount, the rate that would be applicable under Section 2.6(a) to a Base Rate
Loan, plus 2% per annum, but in no event to exceed the Highest Lawful Rate.

               (d) INTEREST PAYMENT DATES. Interest on each Loan shall accrue
from and including the date of such Loan to but excluding the date of payment in
full thereof. Interest on each Eurodollar Loan shall be payable on the last day
of each Interest Period applicable thereto and, in the case of an Interest
Period in excess of three months, on each day which occurs every three months
after the initial date of such Interest Period, and on any prepayment (on the
amount prepaid), at maturity (whether by acceleration or otherwise) and, after
maturity, on demand. Interest on each Base Rate Loan shall be payable on each
Quarterly Date, commencing on the first of such days to occur after such Loan is
made, at maturity (whether by acceleration or otherwise) and, after maturity, on
demand.

               (e) NOTICE BY THE ADMINISTRATIVE AGENT. The Administrative Agent,
upon determining the Eurodollar Rate for any Interest Period, shall promptly
notify by telecopy or telephone (in the case of telephonic notices, confirmed by
telecopy or otherwise in writing) or in writing the Company and the Lenders.

        Section 2.7 INTEREST PERIODS. In connection with each Borrowing of
Eurodollar Loans, the Company shall elect an Interest Period to be applicable to
such Borrowing, which Interest Period shall begin on and include, as the case
may be, the date selected by the Company pursuant to Section 2.2(a), the
conversion date or the date of expiration of the then current Interest Period
applicable thereto, and end on but exclude the date which is either one, two,
three or six months thereafter, as selected by the Company; PROVIDED that:

               (a) BUSINESS DAYS. If any Interest Period would otherwise expire
on a day which is not a Business Day, such Interest Period shall expire on the
next succeeding Business Day, PROVIDED, FURTHER, that if any Interest Period
(other than in respect of a Borrowing of Eurodollar Loans the Interest Period of
which is expiring pursuant to Section 2.15(b) hereof) would otherwise expire on
a day which is not a Business Day but is a day of the month after which no
further Business Day occurs in such month, such Interest Period shall expire on
the next preceding Business Day;

               (b) MONTH END. Any Interest Period which begins on the last
Business Day of a calendar month (or on a day for which there is no numerically
corresponding day in the calendar month at the end of such Interest Period)
shall, subject to Section (c) below, end on the last Business Day of a calendar
month;

               (c) PAYMENT LIMITATIONS. No Interest Period shall extend beyond
any date that any principal payment or prepayment is scheduled to be due unless
the aggregate principal amount of Borrowings which are Borrowings of Base Rate
Loans or which have Interest Periods which will expire on or before such date,
less the aggregate amount of any other principal payments or prepayments due
during such Interest Period, is equal to or in excess of the amount of such
principal payment or prepayment; and


                                       25
<PAGE>
               (d) MATURITY DATES. No Interest Period with regard to Revolving
Credit Loans shall extend beyond the Revolving Credit Maturity Date and no
Interest Period with regard to Term Loans shall extend beyond the Term Loan
Maturity Date.

        Section 2.8   REPAYMENT OF LOANS.

               (a) The Company hereby unconditionally promises to pay to the
Administrative Agent for the account of each Lender (1), the then unpaid
principal amount of each Revolving Credit Loan of such Lender on the Revolving
Credit Maturity Date (or such earlier date on which the Revolving Credit Loans
become due and payable pursuant to Article 7); and (2) the amounts specified in
Section 2.5(b), on the dates specified in Section 2.5(b) (or such earlier date
on which the Term Loans become due and payable pursuant to Article 7). The
Company hereby further agrees to pay interest on the unpaid principal amount of
the Loans from time to time outstanding from the date hereof until payment in
full thereof at the rates per annum, and on the dates, set forth in Section 2.6.

               (b) Each Lender shall maintain in accordance with its usual
practice an account or accounts evidencing indebtedness of the Company to such
Lender resulting from each Loan of such Lender from time to time, including,
without limitation, the amounts of principal and interest payable and paid to
such Lender from time to time under this Agreement.

               (c) The Administrative Agent shall maintain the Register pursuant
to Section 9.7(d), and a subaccount therein for each Lender, in which shall be
recorded (1) the amount of each Loan made hereunder, the Type thereof and each
Interest Period, if any, applicable thereto, (2) the amount of any principal or
interest due and payable or to become due and payable from the Company to each
Lender hereunder and (3) both the amount of any sum received by the
Administrative Agent hereunder from the Company and each Lender's Applicable
Percentage thereof.

               (d) The entries made in the Register and the accounts of each
Lender maintained pursuant to Section 2.8(c) shall, to the extent permitted by
applicable law, be PRIMA FACIE evidence of the existence and amounts of the
obligations of the Company therein recorded; PROVIDED, HOWEVER, that the failure
of any Lender or the Administrative Agent to maintain the Register or any such
account, or any error therein, shall not in any manner affect the obligation of
the Company to repay (with applicable interest) the Loans made to the Company by
such Lender in accordance with the terms of this Agreement.

        Section 2.9 VOLUNTARY TERMINATION OR REDUCTION OF COMMITMENTS. The
Company may, upon at least three (3) Business Days' notice to the Administrative
Agent, terminate entirely at any time, or partially reduce from time to time by
an aggregate amount of $5,000,000 or any larger multiple of $5,000,000, the
unused portions of the Revolving Credit Commitments, provided that any such
reduction shall apply proportionately to the Revolving Credit Commitment of each
Lender. If the Revolving Credit Commitments are terminated in their entirety,
all accrued commitment fees with respect thereto shall be payable on the
effective date of such termination.

        Section 2.10  PREPAYMENTS AND MANDATORY COMMITMENT REDUCTIONS.

               (a)    MANDATORY PREPAYMENTS AND COMMITMENT REDUCTIONS.

                      (1) If at any time the Aggregate Revolving Credit Exposure
        is in excess of the Maximum Available Amount, the Company shall
        immediately pay to the Administrative Agent, for the account of the
        Lenders, the amount of such excess to be applied (A) as a prepayment of
        the Revolving Credit Loans and Reimbursement Obligations outstanding and
        (B) after payment in full


                                       26
<PAGE>
        of the Revolving Credit Loans and Reimbursement Obligations outstanding,
        as Cover for the Letter of Credit Liabilities in an amount of such
        remaining excess. Any such prepayment or Cover resulting from a
        termination or reduction of the Commitments pursuant to Section 2.9,
        shall be payable or provided in full on the date on which such reduction
        or termination of the Commitments becomes effective.

                      (2) Any or all of the Term Loan Commitments remaining
        unused after the Closing Date shall automatically terminate at 5:00 p.m.
        (Houston, Texas time) on such date.

               (b) VOLUNTARY PREPAYMENTS. The Company may, at its option, at any
time and from time to time, prepay the Loans and the Reimbursement Obligations,
in whole or in part, upon giving, in the case of any Eurodollar Loan, three
Business Days' prior written notice to the Administrative Agent, and, in the
case of any Base Rate Loan, prior written notice on the same Business Day to the
Administrative Agent. Such notice shall specify (1) in the case of any
prepayment of Loans, the date and amount of prepayment and whether the
prepayment is (A) of Term Loans or Revolving Credit Loans, or a combination
thereof and (B) of Eurodollar Loans, Base Rate Loans or a combination thereof,
and, in each case if a combination thereof, the principal amount allocable to
each; and (2) in the case of any prepayment of Reimbursement Obligations, the
date and amount of prepayment, the identity of the applicable Letter of Credit
or Letters of Credit and the amount allocable to each of such Reimbursement
Obligations. Upon receipt of such notice, the Administrative Agent shall
promptly notify each Lender of the contents thereof and of such Lender's
Applicable Percentage of such prepayment. If any such notice is given, the
amount specified in such notice shall be due and payable on the date specified
therein, together with (if a Eurodollar Loan is prepaid other than at the end of
the Interest Period applicable thereto) any amounts payable pursuant to Section
2.18 and, in the case of prepayments of the Term Loans only, accrued interest to
such date on the amount prepaid. Prepayments of (A) the Term Loans pursuant to
this Section 2.10(b) shall be applied ratably to the remaining scheduled
installment payments of the Term Loans required pursuant to Section 2.5(b); and
(B) the Revolving Credit Loans and the Reimbursement Obligations pursuant this
Section shall (unless the Company otherwise directs) be applied, FIRST, to
payment of the Revolving Credit Loans then outstanding, SECOND, to payment of
any Reimbursement Obligations then outstanding and, LAST, to Cover any
outstanding Letter of Credit Liability. Each prepayment of Base Rate Loans shall
be in the minimum principal amount of $500,000 and in integral multiples of
$500,000 and each prepayment of Eurodollar Loans shall be in the minimum
principal amount of $500,000 and in integral multiples of $500,000 or, in the
case of either Base Rate Loans or Eurodollar Loans, the aggregate principal
balance outstanding on the Term Loans or on the Revolving Credit Loans and the
Reimbursement Obligations, as applicable.

               (c) NOTICE BY ADMINISTRATIVE AGENT. Upon receipt of a notice of
prepayment pursuant to this Section, the Administrative Agent shall promptly
notify each Lender of the contents thereof and of such Lender's ratable share of
such prepayment.

        Section 2.11  CONTINUATION AND CONVERSION OPTIONS.

               (a) CONTINUATION. The Company may elect to continue all or any
part of any Borrowing of Eurodollar Loans beyond the expiration of the then
current Interest Period relating thereto by giving Advance Notice (which shall
be irrevocable) to the Administrative Agent of such election, specifying the
Eurodollar Loans or portion thereof to be continued and the Interest Period
therefor. In the absence of such a timely and proper election with regard to
Eurodollar Loans, the Company shall be deemed to have elected to convert such
Eurodollar Loans to Base Rate Loans pursuant to Section 2.11(d).

               (b) AMOUNT OF CONTINUATIONS. All or part of any Eurodollar Loans
may be continued as provided herein, provided that any continuation of such
Loans shall not be (as to each Borrowing of such


                                       27
<PAGE>
Loans as continued for an applicable Interest Period) less than $500,000 and
shall be in an integral multiple of $500,000.

               (c) CONTINUATION OR CONVERSION UPON DEFAULT. If no Default shall
have occurred and be continuing, each Eurodollar Loan may be continued or
converted as provided in this Section. If a Default shall have occurred and be
continuing, the Company shall not have the option to elect to continue any such
Eurodollar Loan pursuant to Section 2.11(a) or to convert Base Rate Loans to
Eurodollar Loans pursuant to Section 2.11(e).

               (d) CONVERSION TO BASE RATE. The Company may elect to convert any

convert any Base Rate Loan at any time or from time to time to a Eurodollar Loan

Agent of such election, specifying each Interest Period therefor.

               (f) AMOUNTS OF CONVERSIONS. All or any part of the outstanding
Loans may be converted as provided herein, provided that any conversion of such
Loans shall not result in a Borrowing of Eurodollar Loans in an amount less than
$500,000 and in integral multiples of $500,000.

        Section 2.12  FEES.

               (a) REVOLVING CREDIT COMMITMENTS. The Company shall pay to the
Administrative Agent for the account of and distribution to each Lender in
accordance with its Revolving Credit Percentage a commitment fee for the period
commencing on the Closing Date, to and including the Revolving Credit Maturity
Date (or such earlier date as the Revolving Credit Commitments shall have been
terminated entirely) computed at a rate per annum equal to the Applicable
Commitment Fee Percentage on the average daily excess amount of the Revolving
Credit Commitments over the Revolving Credit Exposure. The commitment fees on
the Revolving Credit Commitments earned from and after the Closing Date shall be
payable in arrears on each Quarterly Date, commencing on the first Quarterly
Date to occur after the Closing Date.

               (b) LETTERS OF CREDIT.

                      (1) As consideration for acting as the Issuing Bank with
        respect to any Letter of Credit, the Company will pay to the Issuing
        Bank a fee computed at a rate per annum equal to 1/8% of 1% on the daily
        average amount available for drawing on the applicable Letter of Credit,
        payable in arrears on each Quarterly Date. The Company shall also pay to
        the Issuing Bank, with respect to any issuance, amendment, transfer, or
        cancellation prior to expiration of any Letter of Credit and for each
        drawing made thereunder, documentary and processing charges in
        accordance with the Issuing Bank's standard schedule for such charges in
        effect at the time of, and payable at the time of, such issuance,
        amendment, transfer, cancellation or drawing, as the case may be. All
        fees payable pursuant to this clause (1) shall be retained by the
        Issuing Bank.

                      (2) The Company will pay to the Administrative Agent for
        the account of and pro rata distribution to each Lender a fee on the
        daily average amount available for drawings under each Letter of Credit,
        in each case for the period from and including the date of issuance of
        such Letter of Credit to and excluding the date of expiration or
        termination thereof computed at a per annum rate for each day equal to
        the Applicable Margin for Revolving Credit Loans that are


                                       28
<PAGE>
        Eurodollar Loans in effect on such day, provided that each Letter of
        Credit shall bear a minimum fee of $500. Such fees shall be payable in
        arrears on each Quarterly Date.

               (c) FEE LETTER. The Company shall pay to the Administrative Agent
and to Chase Securities Inc. such fees as are set forth in the Fee Letter, as
the same has been or may be hereafter amended or supplemented, on the dates and
in the manner specified therein.

        Section 2.13  PAYMENTS, ETC.

               (a) WITHOUT SETOFF, ETC. Except as otherwise specifically
provided herein, all payments under this Agreement shall be made to the
Administrative Agent for the account of the Lenders without defense, set-off or
counterclaim to the Administrative Agent not later than 11:00 a.m. Houston,
Texas time on the date when due and shall be made in Dollars in immediately
available funds at the Payment Office. The Administrative Agent will promptly
thereafter distribute funds in the form received relating to the payment of
principal or interest or commitment fees ratably to the Lenders for the account
of their respective Lending Offices, and funds in the form received relating to
the payment of any other amount payable to any Lender to such Lender for the
account of its applicable Lending Office.

               (b) NON-BUSINESS DAYS. Whenever any payment to be made hereunder
or under any Note shall be stated to be due on a day which is not a Business
Day, the due date thereof shall be extended to the next succeeding Business Day
(except as otherwise provided in Section 2.7 hereof) and, with respect to
payments of principal, interest thereon shall be payable at the applicable rate
during such extension.

               (c) COMPUTATIONS. All computations of interest shall be made on
the basis of a year of 360 days (unless such calculation would result in a
usurious rate, in which case interest shall be calculated on the basis of a year
of 365 or 366 days, as the case may be) in the case of Eurodollar Loans or Base
Rate Loans that are based upon the Federal Funds Effective Rate, and 365 or 366
days (as the case may be) in the case of Base Rate Loans that are based upon the
Prime Rate, and all computations of fees shall be made on the basis of a year of
360 days (unless such calculation would result in a usurious rate, in which case
interest shall be calculated on the basis of a year of 365 or 366 days, as the
case may be), in each case for the actual number of days (including the first
day but excluding the last day) occurring in the period for which such interest
or fees are payable. Each determination by the Administrative Agent of an
interest rate or fee hereunder shall, except for manifest error, be final,
conclusive and binding for all purposes, provided that such determination shall
be made in good faith in a manner generally consistent with the Administrative
Agent's standard practice. If the Administrative Agent and the Company determine
that manifest error exists, said parties shall correct such error by way of an
adjustment to the payment due on the next Quarterly Date.

        Section 2.14 INTEREST RATE NOT ASCERTAINABLE, ETC. In the event that the
Administrative Agent shall have determined (which determination shall be
reasonably exercised and shall, absent manifest error, be final, conclusive and
binding upon all parties) that on any date for determining the Eurodollar Rate
for any Interest Period, by reason of any changes arising after the date of this
Agreement affecting the interbank Eurodollar market, or any Lender's position in
such market, adequate and fair means do not exist for ascertaining the
applicable interest rate on the basis provided for in the definition of
Eurodollar Rate, then, and in any such event, the Administrative Agent shall
forthwith give notice (by telephone confirmed in writing) to the Company and to
the Lenders of such determination. Until the Administrative Agent notifies the
Company that the circumstances giving rise to the suspension described herein no
longer exist, the obligations of the Lenders to make Eurodollar Loans shall be
immediately suspended; any Borrowing of Eurodollar Loans that is requested (by
continuation, conversion or otherwise) shall instead be made as


                                       29
<PAGE>
a Borrowing of Base Rate Loans, and any outstanding Eurodollar Loan shall be
converted, on the last day of the then current Interest Period applicable
thereto, to a Base Rate Loan.

        Section 2.15  ILLEGALITY.

               (a) DETERMINATIONS OF ILLEGALITY. In the event that any Lender
shall have determined (which determination shall be reasonably exercised and
shall, absent manifest error, be final, conclusive and binding upon all parties)
at any time that the making or continuance of any Eurodollar Loan has become
unlawful as a result of compliance by such Lender in good faith with any
applicable law, governmental rule, regulation, guideline or order (whether or
not having the force of law and whether or not failure to comply therewith would
be unlawful), then, in any such event, the Lender shall give prompt notice (by
telephone confirmed in writing) to the Company and to the Administrative Agent
of such determination (which notice the Administrative Agent shall promptly
transmit to the other Lenders).

               (b) EURODOLLAR LOANS SUSPENDED. Upon the giving of the notice to
the Company referred to in Section 2.15(a) above, (1) the Company's right to
request (by continuation, conversion or otherwise) and such Lender's obligation
to make Eurodollar Loans shall be immediately suspended, and thereafter, any
requested Borrowing of Eurodollar Loans shall, as to such Lender only, be deemed
to be a request for a Base Rate Loan, and (2) if the affected Eurodollar Loan or
Loans are then outstanding, the Company shall immediately, or if permitted by
applicable law, no later than the date permitted thereby, upon at least one
Business Day's written notice to the Administrative Agent and the affected
Lender, convert each such Eurodollar Loan into a Base Rate Loan, provided that
if more than one Lender is affected at any time, then all affected Lenders must
be treated the same pursuant to this subsection.

        Section 2.16  INCREASED COSTS.

               (a) EURODOLLAR REGULATIONS, ETC. If, by reason of (x) the
introduction of or any change (including, but not limited to, any change by way
of imposition or increase of reserve requirements) in or in the interpretation
of any law or regulation, or (y) the compliance with any guideline or request
issued by any central bank or other governmental authority or quasi-governmental
authority exercising control over banks or financial institutions generally
(whether or not having the force of law):

                      (1) any Lender (or its applicable Lending Office) shall be
        subject to any tax, duty or other charge with respect to its Eurodollar
        Loans or its obligation to make Eurodollar Loans, or shall change the
        basis of taxation of payments to any Lender of the principal of or
        interest on its Eurodollar Loans or its obligation to make Eurodollar
        Loans (except for changes in the rate of tax on the overall net income
        or gross receipts of such Lender or its applicable Lending Office
        imposed by the jurisdiction in which such Lender's principal executive
        office or applicable Lending Office is located); or

                      (2) any reserve (including, but not limited to, any
        imposed by the Board of Governors of the Federal Reserve System, but
        excluding any such reserve requirement that is reflected in the
        Eurodollar Rate), special deposit or similar requirement against assets
        of, deposits with or for the account of, or credit extended by, any
        Lender or its applicable Lending Office shall be imposed or deemed
        applicable or any other condition affecting its Eurodollar Loans or its
        obligations to make Eurodollar Loans shall be imposed on any Lender or
        its applicable Lending Office or the interbank Eurodollar market or the
        secondary certificate of deposit market;

and as a result thereof there shall be any increase in the cost to such Lender
of agreeing to make or making, funding or maintaining Eurodollar Loans (except
to the extent already included in the determination of the


                                       30
<PAGE>
applicable Eurodollar Rate) or there shall be a reduction in the amount received
or receivable by such Lender or its applicable Lending Office, then the Company
shall from time to time, upon written notice from and demand by such Lender
(with a copy of such notice and demand to the Administrative Agent), pay to such
Lender on demand additional amounts determined by such Lender in a reasonable
manner to be sufficient to indemnify such Lender against such increased cost. A
certificate as to the amount of such increased cost and the calculation thereof,
submitted to the Company and the Administrative Agent by such Lender, shall,
except for manifest error, be final, conclusive and binding for all purposes.

               (b) COSTS. If any Lender shall advise the Administrative Agent
that at any time, because of the circumstances described in clauses (x) or (y)
in Section 2.16(a) or any other circumstances affecting such Lender or the
interbank Eurodollar market or such Lender's position in such market, the
Eurodollar Rate, as determined in good faith by the Administrative Agent, will
not adequately and fairly reflect the cost to such Lender of funding its
Eurodollar Loans, then, and in any such event:

                      (1) the Administrative Agent shall forthwith give notice
        (by telephone confirmed in writing) to the Company and to the Lenders of
        such advice;

                      (2) the Company's right to request a Borrowing of
        Eurodollar Loans from such Lender and such Lender's obligation to make
        Eurodollar Loans shall be immediately suspended, any such Borrowing of
        Eurodollar Loans that is requested (by continuation, conversion or
        otherwise) shall, as to such Lender only, be deemed to be a request for
        a Base Rate Loan, and any such outstanding Eurodollar Loan from such
        Lender shall be converted, on the last day of the then current Interest
        Period applicable thereto, to a Base Rate Loan.

               (c) CAPITAL ADEQUACY. If, by reason of (1) the introduction of or
any change (including, but not limited to, any change by way of imposition or
increase of reserve requirements) in or in the interpretation of any law or
regulation, or (2) the compliance with any guideline or request issued by any
central bank or other governmental authority or quasi-governmental authority
exercising control over banks or financial institutions generally (whether or
not having the force of law), affects or would affect the amount of capital
required to be maintained by any Lender or any corporation controlling such
Lender, and the amount of such capital is increased by or based upon the
existence of such Lender's Loans or such Lender's commitment to lend hereunder
and other commitments of this type or of the Letters of Credit (or similar
contingent obligations), then, upon written request therefor by such Lender
(with a copy of such request to the Administrative Agent), the Company shall pay
to such Lender, from time to time as specified by such Lender, additional
amounts sufficient to compensate such Lender for the increased cost of such
additional capital in light of such circumstances, to the extent that such
Lender reasonably determines such increase in capital to be allocable to the
existence of such Lender's Loans or such Lender's commitment to lend hereunder
or to the issuance or maintenance of the Letters of Credit. A certificate as to
such amounts and the calculation thereof, submitted to the Company and the
Administrative Agent by such Lender, shall be conclusive and binding for all
purposes, absent manifest error.

               (d) ISSUING BANK. The rights and benefits of the Lenders under
this Section 2.16 shall also apply to the Issuing Bank in its capacity as such.

               (e) TIME LIMIT. The Company shall not compensate any Lender or
the Administrative Agent for any costs payable under this Section 2.16(e)
accruing prior to one hundred eighty (180) days before such lender or the
Administrative Agent requests compensation.

        Section 2.17  CHANGE OF LENDING OFFICE.  Each Lender agrees that it will
use reasonable efforts to designate an alternate Lending Office with respect to
any of its Eurodollar Loans affected by the


                                       31
<PAGE>
matters or circumstances described in Sections 2.14, 2.15 or 2.16 to reduce the
liability of the Company or avoid the results provided thereunder, so long as
such designation is not disadvantageous to such Lender as determined by such
Lender in its sole discretion; provided that such Lender shall have no
obligation to so designate an alternate Lending Office located in the United
States.

        Section 2.18  FUNDING LOSSES.  The Company shall compensate each Lender,
upon its written request (which request shall set forth the basis for requesting
such amounts and shall, absent manifest error, be final, conclusive and binding
upon all of the parties hereto), for all losses, expenses and liabilities
(including, but not limited to, any interest paid by such Lender to lenders of
funds borrowed by it to make or carry its Eurodollar Loans to the extent not
recovered by the Lender in connection with the re-employment of such funds,
which the Lender may sustain: (a) if for any reason (other than a default by
such Lender) a Borrowing of Eurodollar Loans does not occur on the date
specified therefor in a Borrowing Request (whether or not withdrawn), including,
but not limited to a failure by the Company to fulfill on the date of any
Borrowing of Eurodollar Loans the conditions set forth in Article 3, or to
convert or continue any Eurodollar Loan hereunder after irrevocable notice of
such conversion or continuation has been given pursuant to Section 2.11; (b) if
any payment, prepayment or conversion of any of its Eurodollar Loans required or
permitted by any other provision of this Agreement or otherwise, or any
assignment of a Eurodollar Loan pursuant to Section 2.22, in each case is made
or deemed made on a date which is not the last day of the Interest Period
applicable thereto; or (c) if, for any reason, the Company defaults in its
obligation to repay its Eurodollar Loans or interest accrued thereon as and when
due and payable (at the due date thereof, whether at scheduled maturity, by
acceleration, irrevocable notice of prepayment or otherwise).

        Section 2.19 SHARING OF PAYMENTS, ETC. If any Lender shall obtain any
payment or reduction (including, but not limited to, any amounts received as
adequate protection of a deposit treated as cash collateral under the Bankruptcy
Code) of any obligation of the Company hereunder (whether voluntary,
involuntary, through the exercise of any right of set-off, or otherwise) in
excess of its ratable share of payments or reductions on account of such
obligations obtained by all the Lenders, such Lender shall forthwith (a) notify
each of the other Lenders and the Administrative Agent of such receipt, and (b)
purchase from the other Lenders such participations in the affected obligations
as shall be necessary to cause such purchasing Lender to share the excess
payment or reduction, net of costs incurred in connection therewith, ratably
with each of them, provided that if all or any portion of such excess payment or
reduction is thereafter recovered from such purchasing Lender or additional
costs are incurred, the purchase shall be rescinded and the purchase price
restored to the extent of such recovery or such additional costs, but without
interest. The Company agrees that any Lender so purchasing a participation from
another Lender pursuant to this Section may, to the fullest extent permitted by
law, exercise all its rights of payment (including the right of set-off) with
respect to such participation as fully as if such Lender were the direct
creditor of the Company in the amount of such participation.

        Section 2.20  TAXES.

               (a) PAYMENTS FREE AND CLEAR. Any and all payments by or on
account of any obligation of the Company hereunder shall be made free and clear
of and without deduction for any Indemnified Taxes or Other Taxes; PROVIDED that
if the Company shall be required to deduct any Indemnified Taxes or Other Taxes
from such payments, then (1) the sum payable shall be increased as necessary so
that after making all required deductions (including deductions applicable to
additional sums payable under this Section) the Administrative Agent, Lender or
Issuing Bank (as the case may be) receives an amount equal to the sum it would
have received had no such deductions been made, (2) the Company shall make such
deductions, and (3) the Company shall pay the full amount deducted to the
relevant Governmental Authority in accordance with applicable law.


                                       32
<PAGE>
               (b) OTHER TAXES. In addition, the Company shall pay any Other
Taxes to the relevant Governmental Authority in accordance with applicable law.

               (c) INDEMNIFICATION. The Company shall indemnify the
Administrative Agent, each Lender and the Issuing Bank, upon written demand
therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by
the Administrative Agent, such Lender or the Issuing Bank, as the case may be,
on or with respect to any payment by or on account of any obligation of the
Company hereunder (including Indemnified Taxes or Other Taxes imposed or
asserted on or attributable to amounts payable under this Section) and any
penalties, interest and reasonable expenses arising therefrom or with respect
thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or
legally imposed or asserted by the relevant Governmental Authority. A
certificate as to the amount of such payment or liability delivered to the
Company by a Lender or the Issuing Bank, or by the Administrative Agent on its
own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive
absent manifest error.

               (d) RECEIPTS. As soon as practicable after any payment of
Indemnified Taxes or Other Taxes by the Company to a Governmental Authority, the
Company shall deliver to the Administrative Agent the original or a certified
copy of a receipt issued by such Governmental Authority evidencing such payment,
a copy of the return reporting such payment or other evidence of such payment
reasonably satisfactory to the Administrative Agent.

               (e) SURVIVAL. Without prejudice to the survival of any other
agreement contained herein, the agreements and obligations contained in this
Section 2.20 shall survive the payment in full of principal and interest
hereunder.

               (f) LENDER REPRESENTATIONS AND AGREEMENTS. Any Foreign Lender
that is entitled to an exemption from or reduction of withholding tax under the
law of the jurisdiction in which the Company is located, or any treaty to which
such jurisdiction is a party, with respect to payments under this Agreement
shall deliver to the Company (with a copy to the Administrative Agent), at the
time or times prescribed by applicable law, such properly completed and executed
documentation prescribed by applicable law or reasonably requested by the
Company as will permit such payments to be made without withholding or at a
reduced rate.

        Section 2.21 PRO RATA TREATMENT. Subject to Section 2.4(b), each
Borrowing of Revolving Credit Loans shall be made, each payment on account of
any commitment fee in respect of the Revolving Credit Commitments hereunder
shall be allocated by the Administrative Agent, and any reduction of the
Revolving Credit Commitments of the Lenders shall be allocated by the
Administrative Agent, PRO RATA according to the relevant Revolving Credit
Percentages of the Lenders. Subject to Section 2.4(b), each payment (including
each prepayment) on account of principal of and interest on any Revolving Credit
Loans shall be allocated by the Administrative Agent PRO RATA according to the
respective outstanding principal amounts of such Revolving Credit Loans then
held by the Lenders. Each payment on account of principal of and interest on any
Term Loans shall be allocated by the Administrative Agent PRO RATA according to
the respective outstanding principal amounts of such Term Loans then held by the
Lenders. All proceeds (including proceeds from the realization upon the
Collateral) received after acceleration of the maturity of the Loans, shall be
applied FIRST to reimbursement of expenses and indemnities provided for in this
Agreement and the Financing Documents; SECOND, to other Lender Indebtedness
(including, without limitation, Letter of Credit Liabilities) until repaid in
full PRO RATA to each Lender; and, THIRD, to any other Person entitled to
receive such proceeds in accordance with applicable law.

        Section 2.22  REPLACEMENT OF LENDERS.  If any Lender does not make a 
Eurodollar Loan pursuant to Section 2.15, is subject to increased costs pursuant
to Section 2.16, fails to designate an alternate


                                       33
<PAGE>
Lending Office pursuant to Section 2.17, or is owed or reasonably anticipates
being owed additional amounts pursuant to Section 2.20, the Company shall have
the right, if no Default then exists, to replace such Lender with another bank
or financial institution with the consent of the Administrative Agent, which
consent shall not be unreasonably withheld, provided that (a) the obligations of
the Company owing to the Lender being replaced (including such increased costs)
that are not being assigned to the replacement lender shall be paid in full to
the Lender being replaced concurrently with such replacement lender, (b) the
replacement lender shall execute an Assignment and Acceptance pursuant to which
it shall become a party hereto as provided in Section 9.7, and (c) upon
compliance with the provisions for assignment provided in Section 9.7 and the
payment of amounts referred to in clause (a), the replacement lender shall
constitute a "Lender" hereunder and the Lender being so replaced shall no longer
constitute a "Lender" hereunder.

responsibility, either initially or on a continuing basis, to provide any Lender
with any credit or other information with respect thereto, whether coming into
its possession before the consummation of the transactions contemplated herein
or at any time or times thereafter.

               (b) ADMINISTRATIVE AGENT NOT RESPONSIBLE. The Administrative

Agent shall be entitled to refrain from such act or taking such action unless
and until the Administrative Agent shall have received instructions from the
Required Lenders; and the Administrative Agent shall not incur liability to any
Person by reason of so refraining. Without limiting the foregoing, no Lender
shall have any right of action whatsoever against the Administrative Agent as a
result of the Administrative Agent acting or refraining from acting under this

instructions of the Required Lenders, or to the extent required by Section 9.2,
all of the Lenders.

account for the same to the Lenders.

        Section 8.8 MAY TREAT LENDER AS OWNER. The Company, the Administrative
Agent and the Issuing Bank may deem and treat each Lender as the owner of such
Lender's Note for all purposes hereof unless and until a written notice of the
assignment or transfer thereof shall have been filed with the Administrative
Agent. Any request, authority or consent of any Person who at the time of making

conclusive and binding on any subsequent owner, transferee or assignee of such
Note or any promissory note or notes issued in exchange therefor.

cause by the Required Lenders. Upon any such resignation or removal, the
Required Lenders shall have the right, upon five days' notice to the Company, to
appoint a successor Administrative Agent, subject to the approval of the
Company, such approval not to be unreasonably withheld. If no successor
Administrative Agent shall have been so appointed by the Required Lenders, and
shall have accepted such appointment, within 30 days after the retiring
Administrative Agent's giving of notice of resignation or the Required Lenders'
removal of the retiring Administrative Agent, then, upon five days' notice to
the Company, the retiring Administrative Agent may, on behalf of the Lenders,
appoint a successor Administrative Agent (subject to approval of the Company,
such approval not to be unreasonably withheld), which shall be a bank which
maintains an office in the United States, or a commercial bank organized under
the laws of the United States of America or of any State thereof, or any
Affiliate of such bank, having a combined capital and surplus of at least
$250,000,000.

               (b) RIGHTS, POWERS, ETC. Upon the acceptance of any appointment
as Administrative Agent hereunder by a successor Administrative Agent, such
successor Administrative Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations under this Agreement. After any retiring Administrative Agent's
resignation or removal hereunder as Administrative Agent, the provisions of this
Article 8 shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Administrative Agent under this Agreement.

Agreement or to the other Financing Documents or changing in any manner the
rights or obligations of the Lenders or the Company hereunder or thereunder or
(y) waive at the Company's request, on such terms and conditions as the Required
Lenders or the Administrative Agent, as the case may be, may specify in such
instrument, any of the requirements of this Agreement or the other Financing
Documents or any Default and its consequences; PROVIDED, HOWEVER, that no such
waiver and no such amendment, supplement or modification shall:

               (a) reduce the amount or extend the scheduled date of maturity of
any Loan or any Reimbursement Obligation or of any scheduled installment thereof
or reduce the stated rate of any interest or fee payable hereunder or extend the
scheduled date of any payment thereof or modify any provision that provides for
the ratable sharing by the Lenders of any payment or prepayment of Lender
Indebtedness to provide for a non-ratable sharing thereof or increase the amount
or extend the expiration date of any Lender's Revolving Credit Commitment or
Term Loan Commitment or amend, modify or waive any provision of Section 2.19, in
each case without the prior written consent of each Lender directly affected
thereby;

               (b) change the currency in which any Loan or Reimbursement
Obligation is payable or amend, modify or waive any provision of this Section
9.2 or reduce the percentage specified in the definition of Required Lenders, in
each case without the written consent of all of the Lenders;

               (c) release any Guarantor from its obligations under its Guaranty
Agreement;

               (d) amend, modify or waive any provision of Article 8 without the
written consent of the Administrative Agent; or

               (e) amend, modify or waive (1) any Letter of Credit Liability
without the written consent of the Issuing Bank or (2) any Letter of Credit
without the consent of each Lender if such Letter of Credit, after giving effect
to such amendment, modification or waiver, would no longer satisfy the
requirements hereof if such Letter of Credit was being issued AB INITIO at such
time, PROVIDED THAT in all cases other than clauses (1) or (2), only the consent
of the Issuing Bank shall be required to amend, modify or waive any Letter of
Credit.

               Any waiver and any amendment, supplement or modification pursuant
to this Section 9.2 shall apply to each of the Lenders and shall be binding upon
the Company, the Lenders, the Administrative Agent and all future holders of the
Loans. In the case of any waiver, the Company, the Lenders and the
Administrative Agent shall be restored to their former position and rights
hereunder and under the other Financing Documents, and any Default waived shall
be deemed to be cured and not continuing; but no such waiver shall extend to any
subsequent or other Default, or impair any right consequent thereon.

        Section 9.3 NO WAIVER; REMEDIES CUMULATIVE. No failure or delay on the
part of the Company or the Administrative Agent or any Lender or any holder of
any Note in exercising any right or remedy under this Agreement or any other
Financing Document and no course of dealing between the Company and the
Administrative Agent or any Lender or any holder of any Note shall operate as a
waiver thereof, nor shall any single or partial exercise of any right or remedy
under the Notes, this Agreement or any other Financing Document preclude any
other or further exercise thereof or the exercise of any other right or remedy
under the Notes, this Agreement or any other Financing Document. The rights and
remedies herein expressly provided are cumulative and not exclusive of any
rights or remedies which the Company, the Administrative Agent or any Lender
would otherwise have. No notice to or demand on the Company not required under
the Notes, this Agreement or any other Financing Document in any case shall
entitle the Company to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of the Administrative Agent
or the Lenders to any other or further action in any circumstances without
notice or demand.

        Section 9.4   PAYMENT OF EXPENSES, INDEMNITIES, ETC.  The Company agrees
to (and shall be liable for):

               (a) EXPENSES. Whether or not the transactions hereby contemplated
are consummated, pay all reasonable out-of-pocket costs and expenses of the
Administrative Agent, and the Issuing Bank in the administration (both before

the Lenders with respect thereto) of, and in connection with the preparation,
execution and delivery of, recording or filing of, preservation of rights under,
enforcement of, and, after a Default, refinancing, renegotiation or
restructuring of, this Agreement, the Notes, and the other Financing Documents
and any amendment, waiver or consent relating thereto (including, but not
limited to, the reasonable fees and disbursements of counsel for the
Administrative Agent and in the case of enforcement for any of the Lenders) and
promptly reimburse the Administrative Agent for all amounts expended, advanced,
or incurred by the Administrative Agent or the Lenders to satisfy any obligation
of the Company, Holding, or the Subsidiaries under this Agreement or any other
Financing Document;

               (B) INDEMNIFICATION. INDEMNIFY THE ADMINISTRATIVE AGENT, THE
ISSUING BANK AND EACH LENDER, EACH OF THEIR RESPECTIVE OFFICERS, DIRECTORS,

LIABILITIES, DAMAGES OR EXPENSES ARISING BY REASON OF ORDINARY NEGLIGENCE OF ANY
OF THE ADMINISTRATIVE AGENT, THE ISSUING BANK AND EACH LENDER, EACH OF THEIR

EXTENT, CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PARTY

FROM TIME TO TIME THE ADMINISTRATIVE AGENT, THE ISSUING BANK AND THE LENDERS,
EACH PERSON CLAIMING BY, THROUGH, UNDER OR ON ACCOUNT OF ANY OF THE FOREGOING
AND THE RESPECTIVE DIRECTORS, OFFICERS, COUNSEL, EMPLOYEES, AGENTS, AFFILIATES,

ARISING PRIMARILY FROM THE ACTS OR OMISSIONS OF THE ADMINISTRATIVE AGENT OR ANY
LENDER DURING THE PERIOD AFTER WHICH SUCH PERSON, ITS SUCCESSORS OR ASSIGNS

If and to the extent that the obligations of the Company under this Section 9.4
are unenforceable for any reason, the Company hereby agrees to make the maximum
contribution to the payment and satisfaction of such obligations which is
permissible under applicable law. The Company's obligations under this Section
shall survive any termination of this Agreement and the payment of the Notes.

        Section 9.5 RIGHT OF SETOFF. In addition to and not in limitation of all
rights of offset that any Lender or the Issuing Bank may have under applicable
law, each Lender or other holder of a Note, or any other Lender Indebtedness
shall, upon the occurrence of any Event of Default and at any time during the
continuance thereof and whether or not such Lender, the Issuing Bank or such
holder has made any demand or the Company's obligations are matured, have the
right at any time and from time to time, without notice to the Company (any such
notice being expressly waived by the Company) to set-off and apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and other indebtedness at any time owing by any Lender or the Issuing Bank
to or for the credit or the account of the Company against any and all of the
Lender Indebtedness owing to such Lender or the Issuing Bank then outstanding,
subject to the provisions of Section 2.19.

        Section 9.6 BENEFIT OF AGREEMENT. The Notes, this Agreement and the
other Financing Documents shall be binding upon and inure to the benefit of and
be enforceable by the respective successors and assigns of the parties hereto,
provided that the Company may not assign or transfer any of its interest
hereunder or thereunder without the prior written consent of the Lenders.

        Section 9.7   SUCCESSORS AND ASSIGNS; PARTICIPATIONS AND ASSIGNMENTS.

               (a) The provisions of this Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns permitted hereby (including any Affiliate of the Issuing Bank that
issues any Letter of Credit), except that the Company may not assign or
otherwise transfer any of its rights or obligations hereunder without the prior
written consent of each Lender (and any attempted assignment or transfer by the
Company without such consent shall be null and void). Nothing in this Agreement,
expressed or implied, shall be construed to confer upon any Person (other than
the parties hereto, their respective successors and assigns permitted hereby
(including any Affiliate of the Issuing Bank that issues any Letter of Credit)
and, to the extent expressly contemplated hereby, the Related Parties of each of
the Administrative Agent, the Issuing Bank and the Lenders) any legal or
equitable right, remedy or claim under or by reason of this Agreement.

               (b) Any Lender may assign to one or more assignees all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans at the time owing to it); PROVIDED that
(i) except in the case of an assignment to a Lender or an Affiliate of a Lender,
each of the Company and the Administrative Agent (and, in the case of an
assignment of all or a portion of a Commitment or any Lender's obligations in
respect of its Revolving Credit Exposure, the Issuing Bank) must give their
prior written consent to such assignment (which consent shall not be
unreasonably withheld), (ii) except in the case of an assignment to a Lender or
an Affiliate of a Lender or an assignment of the entire remaining amount of the
assigning Lender's Commitment, the amount of the Commitment of the assigning
Lender subject to each such assignment (determined as of the date the Assignment
and Acceptance with respect to such assignment is delivered to the
Administrative Agent) shall not be less than $5,000,000 unless each of the
Company and the Administrative Agent otherwise consent, (iii) each partial
assignment shall be made as an assignment of a proportionate part of all the
assigning Lender's rights and obligations under this Agreement, (iv) the parties
to each assignment shall execute and deliver to the Administrative Agent an
Assignment and Acceptance, together with a processing and recordation fee of
$3,500, and (v) the assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire; and


                                       61
<PAGE>
PROVIDED FURTHER that any consent of the Company otherwise required under this
paragraph shall not be required if an Event of Default has occurred and is
continuing. Subject to acceptance and recording thereof pursuant to Section
9.7(d), from and after the effective date specified in each Assignment and
Acceptance the assignee thereunder shall be a party hereto and, to the extent of
the interest assigned by such Assignment and Acceptance, have the rights and
obligations of a Lender under this Agreement, and the assigning Lender
thereunder shall, to the extent of the interest assigned by such Assignment and
Acceptance, be released from its obligations under this Agreement (and, in the
case of an Assignment and Acceptance covering all of the assigning Lender's
rights and obligations under this Agreement, such Lender shall cease to be a
party hereto but shall continue to be entitled to the benefits of Sections 2.16,
2.18, 2.20 and 9.4). Any assignment or transfer by a Lender of rights or
obligations under this Agreement that does not comply with this paragraph shall
be treated for purposes of this Agreement as a sale by such Lender of a
participation in such rights and obligations in accordance with this Section
9.7(b).

               (c) The Administrative Agent, acting for this purpose as an agent
of the Company, shall maintain at one of its offices in Houston, Texas a copy of
each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitment of,
and principal amount of the Loans and Reimbursement Obligations owing to, each
Lender pursuant to the terms hereof from time to time (the "REGISTER"). The
entries in the Register shall be conclusive, and the Company, the Administrative
Agent, the Issuing Bank and the Lenders may treat each Person whose name is
recorded in the Register pursuant to the terms hereof as a Lender hereunder for
all purposes of this Agreement, notwithstanding notice to the contrary. The
Register shall be available for inspection by the Company, the Issuing Bank and
any Lender, at any reasonable time and from time to time upon reasonable prior
notice.

               (d) Upon its receipt of a duly completed Assignment and
Acceptance executed by an assigning Lender and an assignee, the assignee's
completed Administrative Questionnaire (unless the assignee shall already be a
Lender hereunder), the processing and recordation fee referred to in Section
9.7(b) and any written consent to such assignment required by Section 9.7(b),
the Administrative Agent shall accept such Assignment and Acceptance and record
the information contained therein in the Register. No assignment shall be
effective for purposes of this Agreement unless it has been recorded in the
Register as provided in this paragraph.

               (e) Any Lender may, without the consent of the Company, the
Administrative Agent or the Issuing Bank, sell participations to one or more
banks or other entities (a "PARTICIPANT") in all or a portion of such Lender's
rights and obligations under this Agreement (including all or a portion of its
Commitment and the Loans and Reimbursement Obligations owing to it); PROVIDED
that (i) such Lender's obligations under this Agreement shall remain unchanged,
(ii) such Lender shall remain solely responsible to the other parties hereto for
the performance of such obligations and (iii) the Company, the Administrative
Agent, the Issuing Bank and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement. Any agreement or instrument pursuant to which
a Lender sells such a participation shall provide that such Lender shall retain
the sole right to enforce this Agreement and to approve any amendment,
modification or waiver of any provision of this Agreement; PROVIDED that such
agreement or instrument may provide that such Lender will not, without the
consent of the Participant, agree to any amendment, modification or waiver
described in Sections 9.2(a) or 9.2(b) that affects such Participant. Subject to
this Section 9.7(e), the Company agrees that each Participant shall be entitled
to the benefits of Sections 2.16, 2.18 and 2.20 to the same extent as if it were
a Lender and had acquired its interest by assignment pursuant to Section 9.7(b).
To the extent permitted by law, each Participant also shall be entitled to the
benefits of Section 9.5 as though it were a Lender, provided such Participant
agrees to be subject to Section 2.19 as though it were a Lender.


                                       62
<PAGE>
               (f) A Participant shall not be entitled to receive any greater
payment under Section 2.18 or 2.20 than the applicable Lender would have been
entitled to receive with respect to the participation sold to such Participant,
unless the sale of the participation to such Participant is made with the
Company's prior written consent. A Participant that would be a Foreign Lender if
it were a Lender shall not be entitled to the benefits of Section 2.20 unless
the Company is notified of the participation sold to such Participant and such
Participant agrees, for the benefit of the Company, to comply with Section
2.20(f) as though it were a Lender.

               (g) Any Lender may at any time pledge or assign a security
interest in all or any portion of its rights under this Agreement to secure
obligations of such Lender, including any pledge or assignment to secure
obligations to a Federal Reserve Bank, and this Section 9.7 shall not apply to
any such pledge or assignment of a security interest; PROVIDED that no such
pledge or assignment of a security interest shall release a Lender from any of
its obligations hereunder or substitute any such pledgee or assignee for such
Lender as a party hereto.

               (h) The Company authorizes each Lender to disclose to any
participant or Assignee (each, a "TRANSFEREE") and any prospective Transferee
any and all information in such Lender's possession concerning the Company and
its Affiliates which has been delivered to such Lender by or on behalf of the
Company pursuant to this Agreement or which has been delivered to such Lender by
or on behalf of the Company in connection with such Lender's credit evaluation
of the Company and its Affiliates prior to becoming a party to this Agreement.
No assignment or participation made or purported to be made to any Transferee
shall be effective without the prior written consent of the Company if it would
require it to make any filing with any Governmental Authority or qualify any
Loan or Note under the laws of any jurisdiction, and the Company shall be
entitled to request and receive such information and assurances as it may
reasonably request from any Lender or any Transferee to determine whether any
such filing or qualification is required or whether any assignment or
participation is otherwise in accordance with applicable law.

        Section 9.8   GOVERNING LAW; SUBMISSION TO JURISDICTION; ETC.

               (A) GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS
OF THE PARTIES HEREUNDER AND UNDER THE NOTES SHALL BE CONSTRUED IN ACCORDANCE
WITH AND BE GOVERNED BY THE LAWS OF THE STATE OF TEXAS AND, TO THE EXTENT
CONTROLLING, LAWS OF THE UNITED STATES OF AMERICA.

               (B) SUBMISSION TO JURISDICTION. ANY LEGAL ACTION OR PROCEEDING
WITH RESPECT TO THIS AGREEMENT, THE NOTES OR THE OTHER FINANCING DOCUMENTS MAY
BE BROUGHT IN THE COURTS OF THE STATE OF TEXAS OR OF THE UNITED STATES OF
AMERICA FOR THE SOUTHERN DISTRICT OF TEXAS, AND, BY EXECUTION AND DELIVERY OF
THIS AGREEMENT, THE COMPANY, LENDER AND AGENT HEREBY ACCEPTS FOR ITSELF AND IN
RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE
AFORESAID COURTS. THE COMPANY HEREBY IRREVOCABLY WAIVES ANY OBJECTION,
INCLUDING, BUT NOT LIMITED TO, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON
THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS.

               (C) WAIVER OF CONSEQUENTIAL DAMAGES. TO THE MAXIMUM EXTENT
ALLOWED BY APPLICABLE LAW, EACH OF THE COMPANY, THE ADMINISTRATIVE AGENT, THE
ISSUING BANK AND THE LENDERS (I) IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO
CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR
CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES;
(II) CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR COUNSEL FOR ANY
PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE,


                                       63
<PAGE>
OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO
ENFORCE THE FOREGOING WAIVER; AND (IV) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO
ENTER INTO THIS AGREEMENT, THE OTHER FINANCING DOCUMENTS AND THE TRANSACTIONS
CONTEMPLATED HEREBY AND THEREBY BASED UPON, AMONG OTHER THINGS, THE MUTUAL
WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION.

        Section 9.9 INDEPENDENT NATURE OF LENDERS' RIGHTS. The amounts payable
at any time hereunder to each Lender shall be a separate and independent debt,
and each Lender shall be entitled to protect and enforce its rights arising out
of this Agreement, and it shall not be necessary for any other Lender to be
joined as an additional party in any proceeding for such purpose.

        Section 9.10 INVALIDITY. In the event that any one or more of the
provisions contained in the Notes, this Agreement or in any other Financing
Document shall, for any reason, be held invalid, illegal or unenforceable in any
respect, (a) the Company agrees that such invalidity, illegality or
unenforceability shall not affect any other provision of the Notes, this
Agreement or any other Financing Document and (b) the Company and the
Administrative Agent (acting on behalf and at the direction of the Lenders) will
negotiate in good faith to amend such provision so as to be legal, valid, and
enforceable.

        Section 9.11 RENEWAL, EXTENSION OR REARRANGEMENT. All provisions of this
Agreement and of any other Financing Documents relating to the Notes or other
Lender Indebtedness shall apply with equal force and effect to each and all
promissory notes hereafter executed which in whole or in part represent a
renewal, extension for any period, increase or rearrangement of any part of the
Lender Indebtedness originally represented by the Notes, or of any part of such
other Lender Indebtedness.

        Section 9.12 CONFIDENTIALITY. Each of the Administrative Agent, the
Issuing Bank and the Lenders agrees to maintain the confidentiality of the
Information (as defined below), except that Information may be disclosed (a) to
its and its Affiliates' directors, officers, employees and agents, including
accountants, legal counsel and other advisors (it being understood that the
Persons to whom such disclosure is made will be informed of the confidential
nature of such Information and instructed to keep such Information
confidential), (b) to the extent requested by any regulatory authority, (c) to
the extent required by applicable laws or regulations or by any subpoena or
similar legal process, (d) to any other party to this Agreement, (e) in
connection with the exercise of any remedies hereunder or any suit, action or
proceeding relating to this Agreement or the enforcement of rights hereunder,
(f) subject to an agreement containing provisions substantially the same as
those of this Section, to any assignee of or Participant in, or any prospective
assignee of or Participant in, any of its rights or obligations under this
Agreement, (g) with the consent of the Company or (h) to the extent such
Information (i) becomes publicly available other than as a result of a breach of
this Section or (ii) becomes available to the Administrative Agent, the Issuing
Bank or any Lender on a nonconfidential basis from a source other than the
Company. For the purposes of this Section, "INFORMATION" means all information
received from the Company relating to the Company or its business, other than
any such information that is available to the Administrative Agent, the Issuing
Bank or any Lender on a nonconfidential basis prior to disclosure by the
Company; PROVIDED that, in the case of information received from the Company
after the date hereof, such information is clearly identified at the time of
delivery as confidential. Any Person required to maintain the confidentiality of
Information as provided in this Section shall be considered to have complied
with its obligation to do so if such Person has exercised the same degree of
care to maintain the confidentiality of such Information as such Person would
accord to its own confidential information.

        Section 9.13 INTEREST. It is the intention of the parties hereto to
conform strictly to usury laws applicable to the Administrative Agent, the
Issuing Bank and the Lenders (collectively, the "FINANCING PARTIES") and the
Transactions. Accordingly, if the Transactions would be usurious as to any
Financing Party


                                       64
<PAGE>
under laws applicable to it, then, notwithstanding anything to the contrary in
the Notes, this Agreement or in any other Financing Document or agreement
entered into in connection with the Transactions or as security for the Notes,
it is agreed as follows: (a) the aggregate of all consideration which
constitutes interest under law applicable to any Financing Party that is
contracted for, taken, reserved, charged or received by such Financing Party
under the Notes, this Agreement or under any of such other Financing Documents
or agreements or otherwise in connection with the Transactions shall under no
circumstances exceed the maximum amount allowed by such applicable law, (b) in
the event that the maturity of the Notes is accelerated for any reason, or in
the event of any required or permitted prepayment, then such consideration that
constitutes interest under law applicable to any Financing Party may never
include more than the maximum amount allowed by such applicable law, and (c)
excess interest, if any, provided for in this Agreement or otherwise in
connection with the Transactions shall be canceled automatically by such
Financing Party and, if theretofore paid, shall be credited by such Financing
Party on the principal amount of the Company's Indebtedness to such Financing
Party (or, to the extent that the principal amount of the Company's Indebtedness
to such Financing Party shall have been or would thereby be paid in full,
refunded by such Financing Party to the Company). The right to accelerate the
maturity of the Notes does not include the right to accelerate any interest
which has not otherwise accrued on the date of such acceleration, and the
Financing Parties do not intend to collect any unearned interest in the event of
acceleration. All sums paid or agreed to be paid to the Financing Parties for
the use, forbearance or detention of sums included in the Lender Indebtedness
shall, to the extent permitted by law applicable to such Financing Party, be
amortized, prorated, allocated and spread throughout the full term of the Notes
until payment in full so that the rate or amount of interest on account of the
Lender Indebtedness does not exceed the applicable usury ceiling, if any. As
used in this Section, the terms "APPLICABLE LAW" or "LAWS APPLICABLE TO ANY
FINANCING PARTY" shall mean the law of any jurisdiction whose laws may be
mandatorily applicable notwithstanding other provisions of this Agreement, or
law of the United States of America applicable to any Financing Party and the
Transactions which would permit such Financing Party to contract for, charge,
take, reserve or receive a greater amount of interest than under such
jurisdiction's law. To the extent that Article 5069-1.04 of the Texas Revised
Civil Statutes is relevant to any Financing Party for the purpose of determining
the Highest Lawful Rate, such Financing Party hereby elects to determine the
applicable rate ceiling under such Article by the indicated (weekly) rate
ceiling from time to time in effect, subject to such Financing Party's right
subsequently to change such method in accordance with applicable law.

        Section 9.14 EXISTING CREDIT AGREEMENT. This Agreement amends and
restates in its entirety the Existing Credit Agreement, and the "Commitments"

        Section 1.3 CREDIT AGREEMENT DEFINITIONS. Unless otherwise defined
herein, all terms beginning with a capital letter which are defined in the
Credit Agreement shall have the same meanings herein as therein.

                                    ARTICLE 2

                                  THE GUARANTY

        Section 2.1 LIABILITIES GUARANTEED. Guarantor hereby irrevocably and
unconditionally guarantees the prompt payment of the Liabilities when due,
whether at maturity or otherwise, provided, however, that, notwithstanding
anything herein or in any other Financing Document to the contrary, the maximum
liability of Guarantor hereunder shall in no event exceed the Maximum Guaranteed
Amount.

        Section 2.2 NATURE OF GUARANTY. This Guaranty Agreement is an absolute,
irrevocable, completed and continuing guaranty of payment and not a guaranty of
collection, and no notice of the Liabilities or any extension of credit already
or hereafter contracted by or extended to Company need be given to Guarantor.
This Guaranty Agreement may not be revoked by Guarantor and shall continue to be
effective with respect to debt under the Liabilities arising or created after
any attempted revocation by Guarantor and shall remain in full force and effect
until the Liabilities are paid in full and the Commitments are terminated,
notwithstanding that from time to time prior thereto no Liabilities may be
outstanding. The Company and the Lenders may modify, alter, rearrange, extend
for any period and/or renew from time to time, the Liabilities, and the Lenders
may waive any Default or Events of Default without notice to the Guarantor and
in such event Guarantor will remain fully bound hereunder on the Liabilities.
This Guaranty Agreement shall continue to be effective or be reinstated, as the
case may be, if at any time any payment of the Liabilities is rescinded or must
otherwise be returned by any of the Lenders upon the insolvency, bankruptcy or
reorganization of the Company or otherwise, all as though such payment had not
been made. This Guaranty Agreement may be enforced by the Agent and any
subsequent holder of any of the Liabilities and shall not be discharged by the
assignment or negotiation of all or part of the Liabilities. Except as
specifically required in this Guaranty, Guarantor hereby expressly waives
presentment, demand, notice of non-payment, protest and notice of protest and
dishonor, notice of Default or Event of Default, notice of intent to accelerate
the maturity and notice of acceleration of the maturity and any other notice in
connection with the Liabilities, and also notice of acceptance of this Guaranty
Agreement, acceptance on the part of the Lenders being conclusively presumed by
the Lenders' request for this Guaranty Agreement and delivery of the same to the
Agent.

        Section 2.3 AGENT'S RIGHTS. Guarantor authorizes the Agent, without
notice or demand and without affecting Guarantor's liability hereunder, to take
and hold security for the payment of this Guaranty Agreement and/or the
Liabilities, and exchange, enforce, waive and release any such security; and to
apply such security and direct the order or manner of sale thereof as the Agent
in its discretion may determine; and to obtain a guaranty of the Liabilities
from any one or more Persons and at any time or times to enforce, waive,
rearrange, modify, limit or release any of such other Persons from their
obligations under such guaranties.

        Section 2.4   GUARANTOR'S WAIVERS.

               (a) GENERAL. Guarantor waives any right to require any of the
        Lenders to (i) proceed against the Company or any other person liable on
        the Liabilities, (ii) enforce any of their rights against any other
        guarantor of the Liabilities, (iii) proceed or enforce any of their
        rights against or exhaust any security given to secure the Liabilities,
        (iv) have the Company joined with Guarantor in any suit arising out of
        this Guaranty Agreement and/or the Liabilities, or (v) pursue any other


                                       E-5
<PAGE>
        remedy in the Lenders' powers whatsoever. The Lenders shall not be
        required to mitigate damages or take any action to reduce, collect or
        enforce the Liabilities. Guarantor waives any defense arising by reason
        of any disability, lack of corporate authority or power, or other
        defense of the Company or any other guarantor of the Liabilities, and
        shall remain liable hereon regardless of whether the Company or any
        other guarantor be found not liable thereon for any reason. Whether and
        when to exercise any of the remedies of the Lenders under any of the
        Financing Documents shall be in the sole and absolute discretion of the
        Agent, and no delay by the Agent in enforcing any remedy, including
        delay in conducting a foreclosure sale, shall be a defense to the
        Guarantor's liability under this Guaranty Agreement.

               (b) SUBROGATION. Until the Liabilities have been paid in full,
        the Guarantor waives all rights of subrogation or reimbursement against
        the Company, whether arising by contract or operation of law (including,
        without limitation, any such right arising under any federal or state
        bankruptcy or insolvency laws) and waives any right to enforce any
        remedy which the Lenders now have or may hereafter have against the
        Company, and waives any benefit or any right to participate in any
        security now or hereafter held by the Agent or any Lender.

        Section 2.5 MATURITY OF LIABILITIES; PAYMENT. Guarantor agrees that if
the maturity of any of the Liabilities is accelerated by bankruptcy or
otherwise, such maturity shall also be deemed accelerated for the purpose of
this Guaranty Agreement without demand or notice to Guarantor. Guarantor will,
forthwith upon notice from the Agent, pay to the Agent the amount due and unpaid
by the Company and guaranteed hereby. The failure of the Agent to give this
notice shall not in any way release Guarantor hereunder.

        Section 2.6 AGENT'S EXPENSES. If Guarantor fails to pay the Liabilities
after notice from the Agent of the Company's failure to pay any Liabilities at
maturity, and if the Agent obtains the services of an attorney for collection of
amounts owing by Guarantor hereunder, or obtaining advice of counsel in respect
of any of their rights under this Guaranty Agreement, or if suit is filed to
enforce this Guaranty Agreement, or if proceedings are had in any bankruptcy,
probate, receivership or other judicial proceedings for the establishment or
collection of any amount owing by Guarantor hereunder, or if any amount owing by
Guarantor hereunder is collected through such proceedings, Guarantor agrees to
pay to the Agent the Agent's reasonable attorneys' fees.

        Section 2.7 LIABILITY. It is expressly agreed that the liability of the
Guarantor for the payment of the Liabilities guaranteed hereby shall be primary
and not secondary.

        Section 2.8 EVENTS AND CIRCUMSTANCES NOT REDUCING OR DISCHARGING
GUARANTOR'S OBLIGATIONS. Guarantor hereby consents and agrees to each of the
following to the fullest extent permitted by law, and agrees that Guarantor's
obligations under this Guaranty Agreement shall not be released, diminished,
impaired, reduced or adversely affected by any of the following, and waives any
rights (including without limitation rights to notice) which Guarantor might
otherwise have as a result of or in connection with any of the following:

               (a) MODIFICATIONS, ETC. Any renewal, extension, modification,
        increase, decrease, alteration or rearrangement of all or any part of
        the Liabilities, or of the Notes, or the Credit Agreement or any
        instrument executed in connection therewith, or any contract or
        understanding between the Company and any of the Lenders, or any other
        Person, pertaining to the Liabilities;


                                       E-6

               (b) ADJUSTMENT, ETC. Any adjustment, indulgence, forbearance or
        compromise that might be granted or given by any of the Lenders to the
        Company or Guarantor or any Person liable on the Liabilities;

               (c) CONDITION OF COMPANY OR GUARANTOR. The insolvency, bankruptcy
        arrangement, adjustment, composition, liquidation, disability,
        dissolution, death or lack of power of the Company or Guarantor or any
        other Person at any time liable for the payment of all or part of the
        Liabilities; or any dissolution of the Company or Guarantor, or any
        sale, lease or transfer of any or all of the assets of the Company or
        Guarantor, or any changes in the shareholders, partners, or members of
        the Company or Guarantor; or any reorganization of the Company or
        Guarantor;

               (d) INVALIDITY OF LIABILITIES. The invalidity, illegality or
        unenforceability of all or any part of the Liabilities, or any document
        or agreement executed in connection with the Liabilities, for any reason
        whatsoever, including without limitation the fact that the Liabilities,
        or any part thereof, exceed the amount permitted by law, the act of
        creating the Liabilities or any part thereof is ULTRA VIRES, the
        officers or representatives executing the documents or otherwise
        creating the Liabilities acted in excess of their authority, the
        Liabilities violate applicable usury laws, the Company has valid
        defenses, claims or offsets (whether at law, in equity or by agreement)
        which render the Liabilities wholly or partially uncollectible from the
        Company, the creation, performance or repayment of the Liabilities (or
        the execution, delivery and performance of any document or instrument
        representing part of the Liabilities or executed in connection with the
        Liabilities, or given to secure the repayment of the Liabilities) is
        illegal, uncollectible, legally impossible or unenforceable, or the
        Credit Agreement or other documents or instruments pertaining to the
        Liabilities have been forged or otherwise are irregular or not genuine
        or authentic;

               (e) RELEASE OF OBLIGORS. Any full or partial release of the
        liability of the Company on the Liabilities or any part thereof, of any
        co-guarantors, or any other Person now or hereafter liable, whether
        directly or indirectly, jointly, severally, or jointly and severally, to
        pay, perform, guarantee or assure the payment of the Liabilities or any
        part thereof, it being recognized, acknowledged and agreed by Guarantor
        that Guarantor may be required to pay the Liabilities in full without
        assistance or support of any other Person, and Guarantor has not been
        induced to enter into this Guaranty Agreement on the basis of a
        contemplation, belief, understanding or agreement that other parties
        other than the Company will be liable to perform the Liabilities, or the
        Lenders will look to other parties to perform the Liabilities.

               (f) OTHER SECURITY. The taking or accepting of any other
        security, collateral or guaranty, or other assurance of payment, for all
        or any part of the Liabilities;

               (g) RELEASE OF COLLATERAL, ETC. Any release, surrender, exchange,
        subordination, deterioration, waste, loss or impairment (including
        without limitation negligent, willful, unreasonable or unjustifiable
        impairment) of any collateral, property or security, at any time
        existing in connection with, or assuring or securing payment of, all or
        any part of the Liabilities;

               (h) CARE AND DILIGENCE. The failure of the Lenders or any other
        Person to exercise diligence or reasonable care in the preservation,
        protection, enforcement, sale or other handling or treatment of all or
        any part of such collateral, property or security;


                                       E-7
<PAGE>
               (i) PAYMENTS RESCINDED. Any payment by the Company to the Lenders
        is held to constitute a preference under the bankruptcy laws, or for any
        reason the Lenders are required to refund such payment or pay such
        amount to the Company or someone else; or

               (j) OTHER ACTIONS TAKEN OR OMITTED. Any other action taken or
        omitted to be taken with respect to the Credit Agreement, the
        Liabilities, or the security and collateral therefor, whether or not
        such action or omission prejudices Guarantor or increases the likelihood
        that Guarantor will be required to pay the Liabilities pursuant to the
        terms hereof; it being the unambiguous and unequivocal intention of
        Guarantor that Guarantor shall be obligated to pay the Liabilities when
        due, notwithstanding any occurrence, circumstance, event, action, or
        omission whatsoever, whether contemplated or uncontemplated, and whether
        or not otherwise or particularly described herein, except for the full
        and final payment and satisfaction of the Liabilities.

        Section 2.9 RIGHT OF SUBROGATION AND CONTRIBUTION. If Guarantor makes a
payment in respect of the Liabilities, it shall be subrogated to the rights of
the Lenders against the Company with respect to such payment and shall have the
rights of contribution against the other Subsidiary Guarantors set forth in
Section 2.9 of the Subsidiary Guarantors' Guaranty Agreements; provided that
Subsidiary Guarantor shall not enforce its rights to any payment by way of
subrogation or by exercising its rights of contribution or reimbursement or the
right to participate in any security now or hereafter held by or for the benefit
of the Lenders until the Liabilities have been paid in full. The Guarantor
agrees that after all the Liabilities have been paid in full that if its then
current Net Payments are less than the amount of its then current Contribution
Obligation, Guarantor shall pay to the other Subsidiary Guarantors an amount
(together with any payments required of the other Subsidiary Guarantors by
Section 2.9 of each other Guaranty Agreement) such that the Net Payments made by
all Subsidiary Guarantors in respect of the Liabilities shall be shared among
all of the Subsidiary Guarantors in proportion to their respective Contribution
Percentage.

                                    ARTICLE 3

Liabilities and any extension of credit thereunder) that:

               (a) BENEFIT TO GUARANTOR. Guarantor's guaranty pursuant to this
        Guaranty Agreement reasonably may be expected to benefit, directly or

        organized, legally existing and in good standing under the laws of the
        State of ______________ and is duly qualified as a foreign corporation
        in all jurisdictions wherein the property owned or the business
        transacted by it makes such qualification necessary and where failure to
        so qualify would have a Material Adverse Effect.

               (c) CORPORATE POWER AND AUTHORIZATION. Guarantor is duly
        authorized and empowered to execute, deliver and perform this Guaranty
        Agreement and all corporate action on Guarantor's part requisite for the
        due execution, delivery and performance of this Guaranty Agreement has
        been duly and effectively taken.

               (d) BINDING OBLIGATIONS. This Guaranty Agreement constitutes
        valid and binding obligations of Guarantor, enforceable in accordance

        bankruptcy, insolvency or similar laws generally affecting the
        enforcement of creditors' rights).

               (e) NO LEGAL BAR OR RESULTANT LIEN. This Guaranty Agreement will
        not violate any provisions of Guarantor's articles or certificate of
        incorporation, bylaws, or any contract, agreement, law, regulation,
        order, injunction, judgment, decree or writ to which Guarantor is
