     accounts of the Company and its wholly-owned subsidiaries.  All 
     significant intercompany balances and transactions have been eliminated. 
     The condensed consolidated financial statements for periods reported 
     should be read in conjunction with the annual consolidated financial 
     statements and notes related thereto.  The condensed consolidated 
     balance sheet as of December 31, 1996, and the statement of 
     shareholders' equity for the year then ended were derived from audited 
     financial statements, but do not include all disclosures required by 
     generally accepted accounting principles.

     On May 24, 1996, the Company issued 6,250,000 shares of its Common Stock 
     to acquire all of the outstanding common stock of LDG Management Company 
     Incorporated ("LDG").  This business combination was accounted for as a 
     pooling-of-interests.  The Company's 1996 condensed consolidated 
     financial statements have been restated to include the accounts and 
     operations of LDG for all periods presented.

     INCOME TAX

     For the three months ended March 31, 1997 and 1996, the income tax 
     provision has been calculated based on an estimated effective tax rate 
     for each of the fiscal years. The difference between the Companies' 
     effective tax rate and the Federal statutory rate is primarily the 
     result of nontaxable municipal bond interest included in pretax income.  
     In addition, during the three months ended March 31, 1996, LDG was an S 
     Corporation and thus exempt from Federal income tax.

     EARNINGS PER SHARE

     Earnings per share are based on the weighted average number of common 
     and common equivalent shares outstanding during the period divided into 
     net earnings. Weighted average shares outstanding for 1996 have been 
     adjusted to include the shares issued in connection with the combination 
     with LDG. Outstanding common stock options, when dilutive, are considered 
     to be common stock equivalents for the purpose of this calculation.  The 
     treasury stock method is used to calculate common stock equivalents due 
     to options.

     EFFECTS ON RECENT ACCOUNTING PRONOUNCEMENTS

     In February, 1997, the Financial Accounting Standards Board issued SFAS 
     No. 128 "Earnings Per Share".  SFAS No. 128 is effective for fiscal 
     periods ending after December 15, 1997.  Early application is not 
     permitted.  SFAS No. 128 modifies the denominator to be used in the 
     earnings per share calculations, and requires additional disclosures of 
     the calculations.  The statement will have no effect on the Company's 
     net earnings, shareholders' equity or cash flows and an insignificant 
     effect on earnings per share.

     RECLASSIFICATIONS

     Certain amounts in the 1996 condensed consolidated financial statements 
     have been reclassified to conform to the 1997 presentation.  Such 
     reclassifications had no effect on the Company's shareholders' equity, 
     net earnings or cash flows.

(2)  REINSURANCE

     In the normal course of business the Company's insurance company 
     subsidiaries cede a substantial portion of their premium to unrelated 
     domestic and foreign reinsurers through quota share, surplus, excess of 
     loss and facultative reinsurance agreements.  Although the ceding of 
     reinsurance does not discharge the primary insurer from liability to its 
     policyholder, the subsidiaries participate in such agreements for the 
     purpose of limiting their loss exposure and diversifying their business. 
     Substantially all of the reinsurance assumed by the Company's insurance 
     company subsidiaries, was underwritten directly by the subsidiaries but 
     issued by other unrelated companies in order to satisfy local licensing 
     or other requirements, predominantly on foreign business or as 
     reinsurance of captives.  The following table represents the approximate 
     effect of such reinsurance transactions on net premium and loss and loss 
     adjustment expense:

(2)  REINSURANCE, continued

     The insurance company subsidiaries require reinsurers not authorized by 
     their respective states of domicile to collateralize their reinsurance 
     obligations to the Company with letters of credit or cash deposits.  At 
     March 31, 1997, the Company held letters of credit and cash deposits 
     in the amounts of $82.5 million and $8.9 million, respectively, to 
     collateralize certain reinsurance balances.  The Company has established 
     a reserve of $2.4 million as of March 31, 1997, to reduce the effects of 
     any recoverable problems.  In order to minimize its exposure to 
     reinsurance credit risk, the Company evaluates the financial condition 
     of their reinsurers and places their reinsurance with a diverse group of 
     financially sound companies.

(3)  ACQUISITIONS

     TRM

     On January 24, 1997, the Company acquired all of the occupational 
     accident business of the TRM International, Inc. group of companies 
     in exchange for 266,667 shares of the Company's Common Stock and 
     $6.55 million in cash.  This acquisition has been accounted for as a 
     purchase and results of operations of the business acquired has been 
     included in condensed consolidated statements of earnings beginning in 
     January 1997.  Cost in excess of net assets acquired (goodwill) of 
     approximately $13.5 million was recorded from this acquisition, which is 
     being amortized over twenty years.

     INTERWORLD

     On January 6, 1997, the Company announced that it had agreed in 
     principal to acquire all of the outstanding shares of Interworld 
     Corporation in exchange for 725,000 shares of the Company's Common
     Stock.  The transaction was finalized on April 30, 1997 and will be
     accounted for as a pooling-of-interests.  However, the Company's
     consolidated financial statements will not be restated due to
     immateriality.

     AVEMCO

     On January 17, 1997, HCCH and AVEMCO Corporation ("AVEMCO") jointly 
     announced that the Companies had signed a letter of intent to merge in a 
     stock for stock transaction, each share of AVEMCO common stock to be 
     exchanged for one share of HCCH's Common Stock.  The Companies executed 
     definitive agreements on February 28, 1997.  This transaction will be 
     accounted for as a pooling-of-interests.  The merger is still subject to 
     approval by the shareholders of both Companies and to certain regulatory 
     approvals.  As of March 31, 1997, there were approximately 8.4 million
     shares of AVEMCO common stock outstanding.

     SOUTHERN

     On April 16, 1997, the Company announced it had agreed in principal to 
     acquire all of the outstanding shares of Southern Aviation Insurance 
     Underwriters, Inc. in exchange for 225,000 shares of the Company's Common
     Stock.  The combination is subject to the parties finalizing definitive
     agreements and is expected to be accounted for as a pooling-of-interests.

MANAGEMENT'S DISCUSSION AND ANALYSIS

QUARTER ENDED MARCH 31, 1997 VERSUS QUARTER ENDED MARCH 31, 1996.

Gross written premium increased 29% to $71.2 million for the first quarter of 
1997 from $55.3 million for the same period in 1996 due primarily to a few 
large policies written in the quarter.  Net written premium for the first 
quarter of 1997 decreased 34% to $21.5 million from $32.8 million for the 
same period in 1996 due to a reduction in marine gross written premium where 
retentions are higher due to the lack of catastrophe exposure and the 
increased use of facultative reinsurance as the market softens.  In addition, 
the first quarter of 1996 was inflated by the initial impact of the reduction 
in the amount of non-catastrophe proportional reinsurance purchased by the 
Company on certain lines of business.  Net earned premium was unchanged at 
$23.2 million for the first quarter of 1997 compared to $23.5 million for the 
same period in 1996.

Fee and commission income increased 31% to $12.5 million for the first 
quarter of 1997 compared to $9.5 million for the same period in 1996 due to 
the higher proportion of ceded premium plus a few large individual 
transactions in the quarter.  The Company expects fee and commission income 
to continue to increase during the remainder of 1997 due to the effects of 
the recent and pending acquisitions.  Net investment income increased 13% to 
$4.1 million for the first quarter of 1997 compared to $3.7 million for the 
same period in 1996 reflecting a higher level of investments.  While 
total revenue only increased 6% to $39.8 million, there was a greater 
portion of non-risk bearing agency income, which, is more profitable.

Net realized investment gains from sales of equity securities were $42,000 
during the first quarter of 1997 compared to gains of $917,000 for the same 
period in 1996.  During 1996, the Company systematically liquidated the vast 
majority of its equity portfolio.  Net realized investment losses from 
disposition of fixed income securities were $104,000 during the first quarter 
of 1996.  There were no dispositions of fixed income securities during the 
first quarter of 1997.

Loss and LAE decreased $2.1 million during the first quarter of 1997, to 
$12.1 million, as the Company's GAAP loss ratio decreased to 51.8% from 60.6% 
due to the partial release of certain reserve redundancies and particularly 
good results on the aviation line of business.

Other operating expense increased 22% to $3.5 million for the first quarter 
of 1997.  These expenses reflect increased 

                                       11
<PAGE>

expenditures required to meet the overall growth in business.  Goodwill 
amortization expense was $241,000 for the first quarter of 1997 compared to 
$72,000 for the first quarter of 1996 and is included in other operating 
expense.

Merger expense respresents non-recurring items incurred to consummate the 
acquisitions and mergers which are or will be accounted for as a 
pooling-of-interests.  The amounts incurred during the first quarter of 1996 
were incurred due to the combination with LDG. The amounts incurred during 
1997 were incurred due to the combination with Interworld Corporation and the 
pending combination with AVEMCO Corporation.

Interest expense increased 30% to $374,000 during the first quarter of 1997 
from $288,000 due to the increased level of indebtedness used to fund the 
cash portion of recent acquisitions.  Currency conversion losses amounted to 
$218,000 compared to losses of $128,000 for the same period in 1996.  

Income tax expense increased $2.9 million, or 102%, to $5.7 million for the 
first quarter of 1997.  The majority of the increase is due to greater 
pre-tax income; however, LDG was an S Corporation, and thus exempt from 
Federal income taxes for the three months ended March 31, 1996.  Had LDG been 
subject to Federal income taxes during that period, income tax expense for 
the first quarter of 1996 would have increased by $1.2 million.

Net earnings increased 20% to $11.4 million for the first quarter of 1997 
from $9.5 million for the same period in 1996.  This increase was principally 
a result of higher underwriting profits and increased fee and commission 
income.

Earnings per share increased 15% to $0.31 for the first quarter of 1997 from 
$0.27 for the first quarter of 1996.  This reflects a 20% increase in net 
earnings partially offset by a 5% increase in weighted average shares 
outstanding.

The Company's insurance company subsidiaries' statutory combined ratio was 
64.1% for the first quarter of 1997, as compared to 79.8% for the same period 
in 1996.  The Company's combined ratio remains significantly better than the 
industry average.

The Company's book value per share was $7.07 as of March 31, 1997, up from 
$6.71 as of December 31, 1996.  Earnings added $0.32 per share to book value 
during the first quarter of 1997, while the unrealized loss incurred during 
the quarter on the investment portfolio, which is entirely marked-to-market, 
amounted to $2.4 million, net of tax, or $0.07 per share.

LIQUIDITY AND CAPITAL RESOURCES

The Company's consolidated cash and investment portfolio increased $15.8 
million or 5% since December 31, 1996, and totaled $339.3 million as of March 
31, 1997, of which $76.5 million was cash and short-term investments.  Total 
assets increased to $839.2 million as of March 31, 1997, from $745.8 million 
as of December 31, 1996.

                      AGREEMENT AND PLAN OF REORGANIZATION


    THIS AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is entered 
into as of the 30th day of April, 1997 by and among HCC Insurance Holdings, 
Inc., a Delaware corporation ("HCCH"), Av Merger Sub, Inc., a Texas 
corporation and a wholly owned subsidiary of HCCH ("Merger Sub"), Interworld 
Corporation ("Holdco"), a Texas corporation, Aviation & Marine Insurance 
Group, Inc. ("Aviation"), a Texas corporation, the sole shareholders of 
Holdco (Jack G. Folmar ("Folmar"), Bonnie Ross Folmar Moore, Connie Ross 
Folmar Stevenson, David S. Folmar and Noma Jean Folmar (Folmar and all of 
such other individual shareholders of Holdco being collectively referred to 
hereinafter as the "Original Shareholders"), and such entities which are 
directly or indirectly controlled by the Original Shareholders or Holdco 
(including Aviation) and which are disclosed on the Holdco Disclosure 
Schedule (as hereinafter defined) being hereinafter referred to as the 
"Affiliated Companies" prior to the Effective Date, hereinafter defined, and 
as the "Subsidiaries" from and after the Effective Date.

                                   RECITALS:

    A.  The Boards of Directors of each of HCCH, Merger Sub and Holdco have 
determined to engage in a transaction pursuant to which (i) Merger Sub will 
merge with and into Holdco (the "Merger"); (ii) the capital stock of Merger 
Sub shall be converted into shares of common stock of Holdco; and (iii) each 
share of Holdco Common Stock as hereinafter defined, outstanding immediately 
prior to the Effective Time (as hereinafter defined) shall be converted into 
shares of common stock, par value $1.00 per share, of HCCH (the "HCCH Common 
Stock") in the manner herein described, all upon the terms and subject to the 
conditions set forth herein.

    B.  The Boards of Directors of Holdco and the Affiliated Companies have 
approved, and the Board of Directors of Holdco has resolved, subject to the 
terms of this Agreement, to recommend that shareholders of Holdco approve, 
the Merger, this Agreement and the Articles of Merger (as defined herein).

    C.  The Board of Directors of HCCH has approved the Merger, this 
Agreement and the Articles of Merger.  HCCH, as the sole shareholder of

Agreement to qualify as a plan of reorganization in accordance with the 
provisions of Section 368(a) of the Internal Revenue Code of 1986, as amended 
(the "Code"), and to be accounted for as a "pooling-of-interests" for 
accounting purposes.

    NOW, THEREFORE, in consideration of the foregoing and the mutual 
representations, warranties, covenants and agreements set forth herein, the 
parties hereto do hereby agree as follows:

                                   ARTICLE I

                                  THE MERGER

    SECTION 1.1  THE MERGER.

    (a)  Subject to the terms and conditions of this Agreement, Merger Sub 
will be merged into Holdco in accordance with the laws of the State of Texas 
("Texas Law"), whereupon the separate existence of Merger Sub shall cease, 
and Holdco shall be the surviving corporation (the "Surviving Corporation").

    (b)  As soon as practicable after satisfaction or, to the extent 
permitted hereunder, waiver of all conditions to the Merger, Holdco and 
Merger Sub shall file articles of merger, in substantially the form attached 
hereto as Exhibit 1.1(b) (the "Articles of Merger"), in the Office of the 
Secretary of the State of Texas, and make all such other filings or 
recordings required by Texas Law in connection with the Merger.  The Merger 
shall become effective at such time as the Articles of Merger are duly filed 
with the Office of the Secretary of the State of Texas, in accordance with 
the relevant provisions of Texas Law (the "Effective Time").  The date on 
which the Effective Time shall occur is referred to herein as the "Effective 
Date."

    (c)  From and after the Effective Time, the Surviving Corporation shall 
possess all the rights, privileges, powers and franchises and be subject to 
all of the restrictions, disabilities and duties of Holdco and Merger Sub, 
all as provided under Texas Law.

    SECTION 1.2  CONVERSION OF SHARES/ACQUISITION OF MINORITY INTERESTS.

    (a)  At the Effective Time, each share of common stock, par value $1.00 
per share, of Merger Sub outstanding immediately prior to the Effective Time 
shall automatically and without any action on the part of the holder thereof, 
be converted into one share of common stock of the Surviving Corporation, and 
690,000 shares of Holdco Common Stock outstanding immediately prior to the 
Effective Time shall automatically and without any action on the part of the 
holder thereof cease to be outstanding and be converted into the absolute and 
irrevocable right to receive in the aggregate 725,000 shares of HCCH Common 
Stock.  The shares of HCCH Common Stock received pursuant to the terms hereof 
shall be distributed to the Original Shareholders on a pro-rata basis.

    (b)  No fractional shares shall be issued and each holder of Holdco 
Common Stock shall be entitled to the nearest whole share of HCCH Common 
Stock rounded upwards if such fractional share exceeds .5 and otherwise 
rounded downwards, PROVIDED, HOWEVER, that HCCH

                                       2
<PAGE>


shall under no circumstances be obligated hereunder to issue shares of HCCH 
Common Stock to the Original Shareholders in excess of an aggregate of 
725,000 shares of HCCH Common Stock.

    SECTION 1.3 EXCHANGE OF CERTIFICATES.

    (a)  Prior to the Effective Date, HCCH shall appoint KeyCorp Shareholder 
Services, Inc. to act as exchange agent (the "Exchange Agent") in the Merger.

    (b)  At the Effective Time, HCCH shall exchange the shares of HCCH Common 
Stock issuable pursuant to Section 1.2 in exchange for all outstanding shares 
of Holdco Common Stock (other than for shares of Holdco Common Stock held by 
any Shareholder who has elected to accept appraisal rights as contemplated by 
Section 1.4).

    (c)  If prior to the Merger, HCCH: (i) recapitalizes either through a 
split-up of its outstanding shares into a greater number, or through a 
combination of its outstanding shares into a lesser number, or reorganizes, 
reclassifies or otherwise changes its outstanding shares into the same or a 
different number of shares of other classes (other than through a split-up or 
a combination of shares provided for in the previous clause), or (ii) 
declares a dividend on its outstanding shares payable in shares or securities 
convertible into shares (but not cash), then the number of shares of HCCH 
Common Stock into which the shares of Holdco Common Stock are to be converted 
will be adjusted in proportion to such change.

    SECTION 1.4 DISSENTING SHARES.
 
    (a)  Notwithstanding any provision of this Agreement to the contrary, the 
shares of any holder of Holdco Common Stock who has demanded and perfected 
appraisal rights for such shares in accordance with Texas Law and who, as of 
the Effective Time, has not effectively withdrawn or lost such appraisal 
rights ("Dissenting Shares") shall not be converted into or represent a right 
to receive HCCH Common Stock pursuant to Section 1.2, but the holder thereof 
shall only be entitled to such rights as are granted by Texas Law.

    (b)  Notwithstanding the provisions of subsection (a), if any holder of 
shares of Holdco Common Stock who demands appraisal of such shares under 
Texas Law shall effectively withdraw such appraisal demand or fail to perfect 
or otherwise lose the right to appraisal, then, as of the later of the 
Effective Time and the occurrence of such event, such shareholder's shares of 
Holdco Common Stock shall automatically be converted into and represent only 
the right to receive HCCH Common Stock, without interest thereon, upon 
surrender of the certificate representing such shares.

    (c)  Holdco shall give HCCH (i) prompt notice of any written demands for 
appraisal of any shares of Holdco Common Stock, withdrawals of such demands, 
and any other instruments served pursuant to Texas Law and received by Holdco 
which relate to any such demand for


                                       3 
<PAGE>


appraisal and (ii) the opportunity to participate in all negotiations and 
proceedings which take place prior to the Effective Time with respect to 
demands for appraisal under Texas Law.

    (d)  If holders of Holdco Common Stock entitled to receive an excess of 
30,000 shares of HCCH Common Stock demand appraisal rights as provided for 
herein and refuse to withdraw such demand prior to the Effective Date, HCCH, 
in its sole and absolute discretion, shall have the right to terminate this 
Agreement.

corporate powers and all material governmental licenses, authorizations, 
consents and approvals (collectively, "Governmental Authorizations") required

Authorizations the failure of which to have obtained would not have a 
Material Adverse Effect, as hereinafter defined, on Holdco or such Affiliated 
Company.  Holdco has delivered to HCCH true and complete copies of Holdco's 
and each Affiliated Company's Articles of Incorporation or Certificate of 
Incorporation, as the case may be, and Bylaws as currently in effect.  Holdco

foreign corporation and is in good standing in each jurisdiction where the

Holdco and each Affiliated Company's corporate powers and have been duly 
authorized by all necessary corporate action, excluding approval by the 
Shareholders in connection with the consummation of the Merger.  This 
Agreement and the Articles of Merger constitute, or upon execution will 
constitute, valid and binding agreements of Holdco and each of the Affiliated

has full right, power and authority to enter into this Agreement, the

     (b)  Neither Holdco, any Affiliated Company nor any corporation or other 
entity which under Section 4001(b) of the Employee Retirement Income Security 
Act of 1974, as amended ("ERISA"), is under common control with Holdco or any 
Affiliated Company  (a "Holdco ERISA Affiliate") maintains or within the past 
five years has maintained, contributed to, or been obligated to contribute 
to, any "Employee Pension Benefit Plan" ("Pension Plan") or any "Employee 
Welfare Benefit Plan" ("Welfare Plan") as such terms are defined in Sections 
3(2) and 3(1) respectively of ERISA, which is subject to ERISA.  Each Pension 
Plan and Welfare Plan disclosed in the Holdco Disclosure Schedule (which 
Plans have been heretofore delivered 

                                      13

<PAGE>

to HCCH) and maintained by Holdco has been maintained in all material 
respects in compliance with their terms and all provisions of ERISA and the 
Code (including rules and regulations thereunder) applicable thereto.

     (c)  No Pension Plan or Welfare Plan is currently subject to an audit or 
other investigation by the IRS, the Department of Labor (the "DOL"), the 
Pension Benefit Guaranty Corporation or any other governmental agency or 
office nor are any such Plans subject to any lawsuits or legal proceedings of 
any kind or to any material pending disputed claims by employees or 
beneficiaries covered under any such Plan or by any other parties.

     (d)  No "prohibited transaction," as defined in Section 406 of ERISA or 
Sec-tion 4975 of the Code, resulting in liability to Holdco, or any 
Affiliated Company, or any Holdco ERISA Affiliate has occurred with respect 
to any Pension Plan or Welfare Plan.  Each of Holdco, each Affiliated Company 
or Original Shareholder has no knowledge of any breach of fiduciary 
responsibility under Part 4 of Title I of ERISA which has resulted in 
liability of Holdco, any Affiliated Company, and Holdco ERISA Affiliate, any 
trustee, administrator or fiduciary of any Pension Plan or Welfare Plan.

     (e)  Neither Holdco, any Affiliated Company, nor any Holdco ERISA 
Affiliate, since January 1, 1986, has maintained or contributed to, or been 
obligated or required to contribute to, a "Multiemployer Plan," as such term 
is defined in Section 4001(a)(3) of ERISA.  Neither Holdco, any Affiliated 
Company, nor any Holdco ERISA Affiliate has either withdrawn, partially or 
completely, or instituted steps to withdraw, partially or completely, from 
any Multiemployer Plan nor has any event occurred which would enable a 
Multiemployer Plan to give notice of and demand payment of any withdrawal 
liability with respect to Holdco, any Affiliated Company, or any Holdco ERISA 
Affiliate.

     (f)  There is no contract, agreement, plan or arrangement covering any 
employee or former employee of Holdco or any Holdco ERISA Affiliate that, 
individually or collectively, could give rise to the payment of any amount 
that would not be deductible pursuant to the terms of Sections 162(a)(I) or 
280G of the Code.

     (g)  With respect to Holdco, each Affiliated Company and each Holdco 
ERISA Affiliate, the Holdco Disclosure Schedule correctly identifies each 
material agreement, policy, plan or other arrangement, whether written or 
oral, express or implied, fixed or contingent, to which Holdco or any 
Affiliated Company is a party or by which Holdco or any Affiliated Company or 
any property or asset of Holdco or any Affiliated Company is bound, which is 
or relates to a pension, option, bonus, deferred compensation, retirement, 
stock purchase, profit-sharing, severance pay, health, welfare, incentive, 
vacation, sick leave, medical disability, hospitalization, life or other 
insurance or fringe benefit plan, policy or arrangement.

     (h)  Neither Holdco, any Affiliated Company, nor any Holdco ERISA 
Affiliate maintains or has maintained or contributed to any Pension Plan that 
is or was subject to Section 302 of Title IV of ERISA or Section 412 of the 
Code.  Holdco and each Affiliated 

                                      14

<PAGE>

Company has made available to HCCH, for each Pension Plan which is intended 
to be "qualified" within the meaning of Section 401(a) of the Code, a copy of 
the most recent determination letter issued by the IRS to the effect that 
each such Plan is so qualified and that each trust created thereunder is tax 
exempt under Section 501 of the Code, and Holdco and each Affiliated Company 
is unaware of any fact or circumstances that would jeopardize the qualified 
status of each such Pension Plan or the tax exempt status of each trust 
created thereunder.

     SECTION 3.16 MATERIAL AGREEMENTS.

     (a)  The Holdco Disclosure Schedule includes a complete and accurate 
list of all contracts, agreements, leases (other than Holdco Property Leases, 
as hereinafter defined), and instruments to which Holdco or any of the 
Affiliated Companies is a party or by which it or its properties or assets 
are bound which individually involve net payments or receipts in excess of 
$25,000 per annum, inclusive of contracts entered into with customers and 
suppliers in the ordinary course of business, or that pertain to employment 
or severance benefits for any officer, director or employee of Holdco or any 
of the Affiliated Companies, whether written or oral, but exclusive of 
contracts, agreements, leases and instruments terminable without penalty upon 
60 days' or less prior written notice to the other party or parties thereto 
(the "Material Holdco Agreements").

     (b)  Neither Holdco nor any Affiliated Company nor, to the knowledge of 
Holdco or any Affiliated Company, any other party is in default under any 
Material Holdco Agreement and no event has occurred which (after notice or 
lapse of time or both) would become a breach or default under, or would 
permit modification, cancellation, acceleration or termination of any 
Material Holdco Agreement or result in the creation of any security interest 
upon, or any person obtaining any right to acquire, any properties, assets or 
rights of Holdco or any Affiliated Company, which, in any such case, has had 
or would reasonably be expected to have a Material Adverse Effect.

     (c)  To the knowledge of Holdco and each Affiliated Company, each such 
Material Holdco Agreement is in full force and effect and is valid and 
legally binding and there are no material unresolved disputes involving or 
with respect to any Material Holdco Agreement.  No party to a Material Holdco 
Agreement has advised Holdco or any Affiliated Company that it intends either 
to terminate a Material Holdco Agreement or to refuse to renew a Material 
Holdco Agreement upon the expiration of the term thereof.  No representation 
or warranty is made that all benefits contemplated in the Material Holdco 
Agreements will be received.

     (d)  Holdco and each Affiliated Company is not in violation of, or in 
default with respect to, any term of its Articles or Certificate of 
Incorporation, as the case may be, or Bylaws.

     SECTION 3.17 PROPERTIES.  To the knowledge of Holdco and each of the 
Affiliated Companies, Holdco or such Affiliated Company owns no real estate, 
and all leases of real property to which Holdco or any of the Affiliated 
Companies is a party or by which it is bound ("Holdco Property Leases") are 
in full force and effect.  To the knowledge of Holdco or any 

                                      15

<PAGE>

Affiliated Company, there exists no default under such Holdco Property 
Leases, nor any event which with notice or lapse of time or both would 
constitute a default thereunder, which default would have a Material Adverse 
Effect.  All of the properties and assets which are owned by Holdco and each 
of the Affiliated Companies are owned by each of them, respectively, free and 
clear of any Lien, except for Liens which do not have a Material Adverse 
Effect.  Holdco and each of the Affiliated Companies have good and 
indefeasible title with respect to such owned properties and assets subject 
to no Liens, other than those permitted under this Section 3.17, to all of 
the properties and assets necessary for the conduct of their business other 
than to the extent that the failure to have such title would not have a 
Material Adverse Effect.

reasonably be expected to have, a Material Adverse Effect.

     SECTION 3.19 LABOR MATTERS.  Neither Holdco nor any of the Affiliated 
Companies is a party to any collective bargaining agreement or other labor 
union contract applicable to persons employed by Holdco or any such 
Affiliated Companies, nor do they know of any activities or proceedings of 
any labor union to organize any such employees.

     SECTION 3.20 COMPLIANCE WITH LAWS.  Except for violations which do not 
have and would not reasonably be expected to have, individually or in the 
aggregate, a Material Adverse Effect, neither Holdco nor any of the 
Affiliated Companies has received notice that it is in violation of, or has 
violated, any applicable provisions of any laws, statutes, ordinances or 
regulations or any term of any judgment, decree, injunction or order binding 
against it.

     SECTION 3.21 TRADEMARKS, TRADENAMES, ETC.  Holdco and the Affiliated

reimburse any expenses of any broker, finder, investment banker or agent in 
connection with the Merger.

     SECTION 3.24 INVESTMENT REPRESENTATION.  The shares of HCCH Common Stock 
to be acquired by the Shareholders pursuant to the Merger will be acquired 
solely for the account of such Shareholders, for investment purposes only and 
not with a view to the distribution thereof.  The Shareholders are not 
participating, directly or indirectly, in any distribution or transfer of 
such HCCH Common Stock, nor are they participating, directly or indirectly, 
in underwriting any such distribution of HCCH Common Stock within the meaning

                                      17

<PAGE>

Shareholder has such knowledge and experience in business matters that he is 
capable of evaluating the merits and risks of an investment in HCCH and the 
acquisition of the shares of HCCH Common Stock, and he is making an informed 
investment decision with respect thereto.  The Shareholders have been 
informed by HCCH that the shares of HCCH Common Stock to be issued pursuant

                                  ARTICLE IV

                    REPRESENTATIONS AND WARRANTIES OF HCCH

     Except as disclosed in a document referring specifically to this 
Agreement or in a document, exhibit, or appendix filed with the Securities 
and Exchange Commission ("SEC") which has been filed on or before the date 
hereof, (collectively referred to herein as the "HCCH Disclosure Schedule") 
which has been delivered to Holdco and the Affiliated Companies on or before 
the date hereof, each of HCCH and Merger Sub represents and warrants to 
Holdco, the Affiliated Companies and the Shareholders as set forth below (it 
being agreed that the disclosure on the HCCH Disclosure Schedule of the 
existence of any document or fact or circumstance or situation relating to 
any representations, warranties, covenants or agreements in any section of 
this Agreement shall be automatically deemed to be disclosure of such 
document or fact or circumstance or situation for purposes of all other 
representations, warranties, covenants and agreements in this Agreement):

     SECTION 4.1 CORPORATE EXISTENCE AND POWER.  HCCH and each of its 
Subsidiaries is a corporation duly incorporated, validly existing and in good 
standing under the laws of the state of its incorporation.  Merger Sub is a

standing under the laws of the State of Texas.  Each of HCCH and each of its 
Subsidiaries has all corporate powers and all material Governmental 
Authorizations required to carry on its business as now conducted, except 
such Governmental Authorizations the failure of which to have obtained would 
not have a Material Adverse Effect on HCCH.  HCCH and each of its 
Subsidiaries is duly qualified to do business as a foreign corporation and is 
in good standing in each jurisdiction where the character of the property 
owned or leased by it or the nature of its activities makes such 
qualification necessary, except where the failure to be so qualified would 
not have a Material Adverse Effect on HCCH.  HCCH has delivered to Holdco 
true and complete copies of HCCH's Certificate of Incorporation and Bylaws 
and Merger Sub's Articles of Organization and Bylaws, each as currently in 
effect.

     SECTION 4.2 CORPORATE AUTHORIZATION.  The execution, delivery and 
performance by HCCH and Merger Sub of this Agreement, the Articles of Merger 
and the Confidentiality Agreement and the consummation by HCCH and Merger Sub 
of the transactions contemplated hereby and thereby are within the corporate 
powers of HCCH and Merger Sub and have been duly authorized by all necessary 
corporate action.  This Agreement, the Articles of Merger and the 
Confidentiality Agreement constitute, or upon execution will constitute, 
valid and binding agreements of HCCH and Merger Sub, respectively, 
enforceable in each case against each in accordance with their respective 
terms, except as such enforcement may be limited by bankruptcy, insolvency or 
other similar laws affecting the enforcement of creditors' rights generally 
or by general principles of equity.

     SECTION 4.3 GOVERNMENTAL AUTHORIZATION.  The execution, delivery and 
performance by HCCH and Merger Sub of this Agreement, the Articles of Merger 
and the Confidentiality Agreement and the consummation of the Merger by HCCH

regulatory agency having authority over HCCH and its Subsidiaries;  and

                                      19

<PAGE>

     (g)  such other filings or registrations with, or authorizations, 
consents or approvals of, governmental bodies, agencies, officials or 
authorities, the failure of which to make or obtain (i) would not reasonably 
be expected to have a Material Adverse Effect on HCCH or (ii) would not 
materially adversely affect the ability of Holdco, any Affiliated Company, 
HCCH or Merger Sub to consummate the transactions contemplated hereby and 
operate their businesses as heretofore operated.

     SECTION 4.4  NON-CONTRAVENTION.  The execution, delivery and performance 
by HCCH and Merger Sub of this Agreement and the Articles of Merger and the 
consummation by HCCH and Merger Sub of the transactions contemplated hereby and 
thereby do not and will not:

     (a)  contravene or conflict with the Articles or Certificate of 
Incorporation, as the case may be, or Bylaws of HCCH or Merger Sub;

     (b)  assuming compliance with the matters referred to in Section 4.3, 
contravene or conflict with or constitute a violation of any provision of any 
law, regulation, judgment, injunction, order or decree binding upon or 
applicable to HCCH or Merger Sub or any Subsidiary of HCCH;

     (c)  conflict with or result in a breach or violation of, or constitute 
a default under, or result in a contractual right to cause the termination or 
cancellation of or loss of a material benefit under, or right to accelerate, 
any material agreement, contract or other instrument binding upon HCCH or 
Merger Sub or any other Subsidiary of HCCH or any material license, 
franchise, permit or other similar authorization held by HCCH or Merger Sub 
or any other Subsidiary of HCCH; or

     (d)  result in the creation or imposition of any Lien on any material 
asset of HCCH or Merger Sub or any other Subsidiary of HCCH,

except, with respect to clauses (b), (c) and (d) above, for contraventions, 
defaults, losses, Liens and other matters referred to in such clauses that in 
the aggregate would not be reasonably expected to have, individually or in 
the aggregate, a Material Adverse Effect on HCCH.

     SECTION 4.5  CAPITALIZATION OF HCCH.

     (a)  The authorized capital stock of HCCH consists of 100,000,000 shares 
of HCCH Common Stock.  As of December 31, 1996, there were 35,850,832 shares 
of HCCH Common Stock issued and outstanding.  All outstanding shares of HCCH 
Common Stock have been duly authorized and validly issued and are fully paid 
and nonassessable and free from any preemptive rights.  Except as set forth 
in this Section and as otherwise contemplated by this Agreement and except as 
disclosed in public filings made by HCCH with the SEC prior to the Closing 
Date or on the HCCH Disclosure Schedule and except for changes since December 
31, 1996 resulting from the exercise of employee and director stock options, 
there are outstanding (i) no shares of capital stock or other voting 
securities of HCCH, (ii) no securities of HCCH convertible into or 

                                      20

<PAGE>

exchangeable for shares of capital stock or voting securities of HCCH and 
(iii) no options or other rights to acquire from HCCH, and no obligation of 
HCCH to issue, any capital stock, voting securities or securities convertible 
into or exchangeable for capital stock or other voting securities of HCCH 
(the items in clauses (i), (ii) and (iii) being referred to collectively as 
the "HCCH Securities").  There are no outstanding obligations of HCCH or any 
of its Subsidiaries to repurchase, redeem or otherwise acquire any HCCH 
Securities.

     (b)  All shares of HCCH Common Stock issued in the Merger shall, upon 
issuance, be fully paid, validly issued and nonassessable.  HCCH has reserved 
sufficient shares of HCCH Common Stock for issuance pursuant to the Merger.

     SECTION 4.6  ORGANIZATION OF MERGER SUB.  The authorized capital stock 
of Merger Sub consists of 1,000 shares of common stock, par value $1.00 per

conducted any business prior to the date hereof and has no assets, 
liabilities or obligations of any nature other than those incident to its 
formation and pursuant to this Agreement.

     SECTION 4.7  SUBSIDIARIES.

     (a)  Each HCCH Subsidiary is a corporation duly incorporated, validly 
existing and in good standing under the laws of its jurisdiction of 
incorporation, has all corporate powers and all material Governmental 
Authorizations required to carry on its business as now conducted, except 
such Governmental Authorizations the failure of which to have obtained would 
not have a Material Adverse Effect on HCCH, and is duly qualified to do 
business as a foreign corporation and is in good standing in each 
jurisdiction where the character of the property owned or leased by HCCH, or 
the nature of its activities make such qualification necessary, except for 
those jurisdictions where failure to be so qualified would not, individually 
or in the aggregate, have a Material Adverse Effect on HCCH.  All 
Subsidiaries and Joint Ventures material to the business of HCCH ("Material 
HCCH Subsidiaries") and their respective jurisdictions of incorporation or 
organization and HCCH's ownership interest therein are identified in the HCCH 
Disclosure Schedule.  Other than its investments in its Subsidiaries and 
Joint Ventures, and shares of stock in publicly held companies aggregating 
less than 10% of such public company's outstanding stock, HCCH does not own, 
directly or indirectly, any outstanding capital stock or equity interest in 
any corporation, partnership, Joint Venture or other entity.

     (b)  All of the outstanding capital stock of, or other ownership 
interests in, each Material HCCH Subsidiary that is owned by HCCH, is owned 
by HCCH, directly or indirectly, free and clear of any material Lien and free 
of any other material limitation or restriction on its rights as owner 
thereof (including any restriction on the right to vote, sell or otherwise 
dispose of such capital stock or other ownership interests), other than those 
imposed by applicable law.  There are no existing options, calls or 
commitments of any character relating to the issued or unissued capital stock 
or other securities or equity interests (collectively, "HCCH Subsidiary 
Securities") of any HCCH Subsidiary.

                                      21

<PAGE>

     SECTION 4.8  SEC FILINGS.

     (a)  HCCH has since October 28, 1992 filed all forms, proxy statements, 
schedules, reports and other documents required to be filed by it with the 
SEC pursuant to the Exchange Act.

     (b)  HCCH has delivered, and will promptly deliver in the case of any of 
the following filed with the SEC on or after the date hereof and prior to the 
Effective Date, to Holdco:

          (i)  its annual reports on Form 10-K for its fiscal years ended 
December 31, 1996, 1995 and 1994;

          (ii)  any current reports on Form 8-K since January 1, 1996 and its 
proxy or information statements relating to meetings of, or actions taken 
without a meeting by, the shareholders of HCCH held since January 1, 1996; and

          (iii)  all of its other reports, statements, schedules and 
registration statements filed with the SEC since December 31, 1995.  None of 
HCCH's Subsidiaries is required to file any forms, reports or other documents 
with the SEC.

     (c)  As of its filing date, no such report or statement filed pursuant 
to the Exchange Act contained any untrue statement of a material fact or 
omitted to state any material fact necessary in order to make the statements 
made therein, in the light of the circumstances under which they were made, 
not misleading.

     (d)  No registration statement filed pursuant to the Securities Act, if 
declared effective by the SEC, as of the date such statement or amendment 
became effective, contained any untrue statement of a material fact or 
omitted to state any material fact required to be stated therein or necessary 
to make the statements therein not misleading.

     SECTION 4.9  FINANCIAL STATEMENTS.  The audited consolidated financial 
statements of HCCH included in its annual reports on Form 10-K and the 
unaudited financial statements of HCCH included in its quarterly reports on 
Form 10-Q referred to in Section 4.8 present fairly, in conformity with 
generally accepted accounting principles applied on a consistent basis 
(except as may be indicated in the notes thereto), the consolidated financial 
position of HCCH and its consolidated subsidiaries as of the dates thereof 
and their consolidated results of operations and cash flows for the periods 
then ended (subject to normal year-end adjustments in the case of any interim 
financial statements).  For purposes of this Agreement, "HCCH Balance Sheet" 
means the consolidated balance sheet of HCCH as of December 31, 1996, and the 
notes thereto, contained in HCCH's annual report on Form 10-K filed with the 
SEC, and "HCCH Balance Sheet Date" means December 31, 1996.

                                      22

<PAGE>

     SECTION 4.10  ABSENCE OF CERTAIN CHANGES.  Except as disclosed in the 
HCCH Disclosure Schedule, since the HCCH Balance Sheet Date, HCCH and each of 
its Subsidiaries have in all material respects conducted their business in 
the ordinary course and there has not been:

     (a)  any Material Adverse Change with respect to HCCH or any event, 
occurrence or development of a state of circumstances or facts known to HCCH, 
which as of the date hereof could reasonably be expected to have a Material 
Adverse Effect on HCCH;

     (b)  any amendment of any material term of any outstanding HCCH 
Securities; 

     (c)  any action by HCCH or, to HCCH's knowledge, any affiliate of HCCH 
which would preclude the ability of HCCH to account for the business 
combination to be effected by the Merger as a pooling-of-interests under 
generally accepted accounting principles; or

     (d)  the entering into of any agreement by HCCH or any person on behalf 
of HCCH to take any of the foregoing actions.

     SECTION 4.11  NO UNDISCLOSED LIABILITIES.  There are no liabilities of 
HCCH or any of its Subsidiaries of any kind whatsoever that are, individually

assets or against or involving any of its officers, directors or employees in 
connection with the business or affairs of HCCH, including, without 
limitation, any such claims for indemnification arising under any agreement 
to which HCCH or any of its Subsidiaries is a party, which could, 
individually or in the aggregate, have a Material Adverse Effect on HCCH.

     SECTION 4.13  TAXES.

     (a)  HCCH and each of its Subsidiaries (i) has filed when due (taking 
into account extensions) with the appropriate federal, state, local, foreign 
and other governmental agencies, all material tax returns, estimates and 
reports required to be filed by it, (ii) either paid when due and payable or 
established adequate reserves or otherwise accrued on the HCCH Balance Sheet 
all material Taxes, and there are no tax deficiencies claimed in writing by 
any Taxing authority and received by HCCH that, in the aggregate, would 
result in any tax liability in excess of the amount of the reserves or 
accruals, and (iii) has or will establish in accordance with its normal 
accounting practices and procedures accruals and reserves that, in the 
aggregate, are adequate for the payment of all Taxes not yet due and payable 
and attributable to any period preceding the Effective Time.  The HCCH 
Disclosure Schedule sets forth those tax returns of HCCH (or any predecessor 
entities) for all periods that currently are the subject of audit by any 
federal, state, local or foreign taxing authority.

     (b)  There are no material taxes, interest, penalties, assessments or 
deficiencies claimed in writing by any taxing authority and received by HCCH 
or any of its Subsidiaries to be due in respect of any tax returns filed by 
HCCH (or any predecessor corporations) or any of its Subsidiaries.  Neither 
HCCH nor any predecessor corporation, nor any of their respective 
Subsidiaries, has executed or filed with the IRS or any other Taxing 
authority any agreement or other document extending, or having the effect of 
extending, the period of assessment or collection of any Taxes.

     (c)  HCCH is not a party to or bound by (or will prior to the Effective 
Date become a party to or bound by) any Tax indemnity, Tax sharing or Tax 
allocation agreement or other similar arrangement which includes a party 
other than HCCH and its Subsidiaries.  Neither HCCH nor any of its 
Subsidiaries has been a member of an affiliated group other than one of which 
HCCH was the common parent, or filed or been included in a combined, 
consolidated or unitary Tax return other than one filed by HCCH (or a return 
for a group consisting solely of its Subsidiaries and predecessors).

     SECTION 4.14  EMPLOYEE BENEFIT PLANS; ERISA.

     (a)  Neither HCCH nor any corporation or other entity which under 
Section 4001(b) of ERISA is under common control with HCCH (an "HCCH ERISA 
Affiliate") maintains or within the past five years has maintained, 
contributed to, or been obligated to contribute to, any Pension Plan or any 
Welfare Plan which is subject to ERISA.  Each Pension Plan and Welfare Plan 
disclosed in the HCCH Disclosure Schedule (which Plans have been heretofore 
delivered to Holdco) and maintained by HCCH has been maintained in all 
material respects in compliance with their terms and all provisions of ERISA 
and the Code (including rules and regulations thereunder) applicable thereto.

     (b)  Neither HCCH nor any HCCH ERISA Affiliate maintains or has 
maintained or contributed to any Pension Plan that is or was subject to 
Section 302 or Title IV of ERISA or

                                      24

<PAGE>

Section 412 of the Code.  HCCH has made available to Holdco and the 
Affiliated Companies, for each Pension Plan which is intended to be 
"qualified" within the meaning of Section 401(a) of the Code, a copy of the 
most recent determination letter issued by the IRS to the effect that each 
such Plan is so qualified and that each trust created thereunder is tax 
exempt under Section 501 of the Code, and HCCH is unaware of any fact or 
circumstances that would jeopardize the qualified status of each such Pension 
Plan or the tax exempt status of each trust created thereunder.

     (c)  To the knowledge of HCCH, no Pension Plan or Welfare Plan is 
currently subject to an audit or other investigation by the IRS, the 
Department of Labor, the Pension Benefit Guaranty Corporation or any other 
governmental agency or office nor are any such Plans subject to any lawsuits 
or legal proceedings of any kind or to any material pending disputed claims 
by employees or beneficiaries covered under any such Plan or by any other 
parties.

     (d)  No "prohibited transaction," as defined in Section 406 of ERISA or 
Section 4975 of the Code, resulting in liability to HCCH or any HCCH ERISA 
Affiliate has occurred with respect to any Pension Plan or Welfare Plan.  
HCCH has no knowledge of any breach of fiduciary responsibility under Part 4 
of Title I of ERISA which has resulted in liability of HCCH, any HCCH ERISA 
Affiliate, any trustee, administrator or fiduciary of any Pension Plan or 
Welfare Plan.

     (e)  Neither HCCH nor any HCCH ERISA Affiliate, since January 1, 1986, 
has maintained or contributed to, or been obligated or required to contribute 
to, a "Multiemployer Plan," as such term is defined in Section 4001(a)(3) of 
ERISA.  Neither HCCH nor any HCCH ERISA Affiliate has either withdrawn, 
partially or completely, or instituted steps to withdraw, partially or 
completely, from any Multiemployer Plan nor has any event occurred which 
would enable a Multiemployer Plan to give notice of and demand payment of any 
withdrawal liability with respect to HCCH or any HCCH ERISA Affiliate.

     (f)  With respect to HCCH and each HCCH ERISA Affiliate, the HCCH 
Disclosure Schedule correctly identifies each material agreement, policy, 
plan or other arrangement, whether written or oral, express or implied, fixed 
or contingent, to which HCCH is a party or by which HCCH or any property or 
asset of HCCH is bound, which is or relates to a pension, option, bonus, 
deferred compensation, retirement, stock purchase, profit-sharing, severance 
pay, health, welfare, incentive, vacation, sick leave, medical disability, 
hospitalization, life or other insurance or fringe benefit plan, policy or 
arrangement.

     SECTION 4.15  MATERIAL AGREEMENTS.

     (a)  The HCCH Disclosure Schedule includes a complete and accurate list 
of all contracts, agreements, leases (other than HCCH Property Leases, as 
hereinafter defined) and instruments to which HCCH or any of its Subsidiaries 
is a party or by which it or its properties or assets are bound which 
individually involve net payments or receipts in excess of $1,000,000 per 
annum, inclusive of contracts that pertain to employment or severance 
benefits for any 

                                      25

<PAGE>

officer, director or employee of HCCH, whether written or oral, but exclusive 
of contracts entered into with customers and suppliers in the ordinary course 
of business or contracts, agreements, leases and instruments terminable 
without penalty by HCCH upon 60 days or less prior written notice to the 
other party or parties thereto (the "Material HCCH Agreements").

     (b)  Neither HCCH, any HCCH Subsidiary, nor, to the knowledge of HCCH, 
any other party is in default under any Material HCCH Agreement and no event 
has occurred which (after notice or lapse of time or both) would become a 
breach or default under, or would permit modification, cancellation, 
acceleration or termination of any Material HCCH Agreement or result in the 
creation of any security interest upon, or any person obtaining any right to 
acquire, any properties, assets or rights of HCCH which, in any such case, 
has had or would reasonably be expected to have a Material Adverse Effect on 
HCCH.

     (c)  To the knowledge of HCCH, each such Material HCCH Agreement is in 
full force and effect and is valid and legally binding and there are no 
material unresolved disputes involving or with respect to any Material HCCH 
Agreement.  No party to a Material HCCH Agreement has advised HCCH or any of 
its Subsidiaries that it intends either to terminate a Material HCCH 
Agreement or to refuse to renew a Material HCCH Agreement upon the expiration 
of the term thereof.

     (d)  Each of HCCH, Merger Sub, and each HCCH Subsidiary is not in 
violation of, or in default with respect to, any term of its Certificate of 
Incorporation or Bylaws.

     SECTION 4.16  PROPERTIES.  To the knowledge of HCCH, all leases of real 
property to which HCCH or any of its Subsidiaries is a party or by which it 
or any of its Subsidiaries is bound ("HCCH Property Leases") which are 
material to the business of HCCH and its Subsidiaries taken as a whole are in 
full force and effect.  To the knowledge of HCCH, there exists no default 
under such HCCH Property Leases, nor any event which with notice or lapse of 
time or both would constitute a default thereunder by HCCH or any of its 
Subsidiaries, which default would have a Material Adverse Effect on HCCH.  
All of the properties and assets which are owned by HCCH and each of its 
Subsidiaries are owned by each of them, respectively, free and clear of any 
Lien, except for Liens which do not have a Material Adverse Effect on HCCH.  
HCCH and each of its Subsidiaries have good and indefeasible title with 
respect to such owned properties and assets subject to no Liens, other than 
those permitted under this Section 4.16, to all of the properties and assets 
necessary for the conduct of their business other than to the extent that the 
failure to have such title would not have a Material Adverse Effect on HCCH.

     SECTION 4.17  ENVIRONMENTAL MATTERS.

     (a)  To the knowledge of HCCH, no notice, notification, demand, request 
for information, citation, summons, complaint or order has been received, no 
complaint has been filed, no penalty has been assessed and no investigation 
or review is pending, or to HCCH's knowledge, has been threatened by any 
governmental entity or other party with respect to any (i) alleged violation 
by HCCH or any of its Subsidiaries of any Environmental Law, (ii) alleged 

                                      26

<PAGE>

failure by HCCH or any such Subsidiary to have any environmental permit, 
certificate, license, approval, registration or authorization required in 
connection with the conduct of its business or (iii) Regulated Activity.

     (b)  To the knowledge of HCCH, neither HCCH nor any of its Subsidiaries 
has any material Environmental Liabilities and there has been no release of 
Hazardous Substances into the environment by HCCH or any such Subsidiary or 
with respect to any of their respective properties which has had, or would be 
reasonably expected to have, a Material Adverse Effect on HCCH.

     SECTION 4.18 LABOR MATTERS.  Neither HCCH nor any of its Subsidiaries is 
a party to any collective bargaining agreement or other labor union contract 
applicable to persons employed by HCCH or any such Subsidiary, nor do the 
executive officers of HCCH know of any activities or proceedings of any labor 
union to organize any such employees.

     SECTION 4.19  COMPLIANCE WITH LAWS.  Except for violations which do not 
have and would not reasonably be expected to have, individually or in the 
aggregate, a Material Adverse Effect on HCCH, neither HCCH nor any of its 
Subsidiaries is in violation of, or has violated, any applicable provisions 
of any laws, statutes, ordinances or regulations or any term of any judgment, 
decree, injunction or order binding against it.

     SECTION 4.20 TRADEMARKS, TRADENAMES, ETC.  HCCH owns or possesses, or 
holds a valid right or license to use, all intellectual property, patents, 
trademarks, tradenames, servicemarks, copyrights and licenses, and all rights 
with respect to the foregoing, necessary for the conduct of its business as 
now conducted, without any known conflict with the rights of others.

     SECTION 4.21 BROKER'S FEES.  Neither HCCH nor Merger Sub, nor anyone 
acting on the behalf or at the request thereof has any liability to any 
broker, finder, investment banker or agent, or has agreed to pay any 
brokerage fees, finder's fees or commissions, or to reimburse any expenses of 
any broker, finder, investment banker or agent in connection with the Merger.

deterioration or facts which are likely to result in a material deterioration 
in the relationship with any customers, supplier, licensor or others 

                                      30

Companies and HCCH following the consummation of the Merger and will furnish 
promptly to Holdco copies of all reports, schedules, registration statements, 
correspondence and other documents filed with or delivered to the SEC,

Companies or the Shareholders hereunder.  In addition, if requested by Holdco

efforts to carry on its business, keep available the services of its officers 
and employees and preserve its relationships with those of its customers, 
suppliers, licensors and others having business relationships with it that 
are material to its business in substantially the same manner as it has prior 
to the date hereof.  If HCCH becomes aware of a material deterioration or 
facts which are likely to result in a material deterioration in the 
relationship with any material customer, supplier, licensor or others having 
business relationships with it, it will promptly bring such information to 
the attention of Holdco in writing.

respective charter and bylaws, by which it, its properties or its assets may 
be bound, and (iii) all decrees, orders, writs, injunctions, judgments, 
statutes, rules and regulations applicable to HCCH and its Subsidiaries and 
their respective properties or assets; except to the extent that the failure 
to comply with matters in clauses (i), (ii) and (iii) would not have a 
Material Adverse Effect on HCCH.

necessary to cause Merger Sub to perform its obligations under this Agreement 
and to consummate the Merger on the terms and conditions set forth in this 
Agreement.  Merger Sub will not issue any shares of its capital stock, any

the Effective Date, cause to be delivered to each person HCCH believes to be 
an "affiliate," as that term is used in paragraphs (c) and (d) of Rule 145 
under the Securities Act, of HCCH a notice informing such persons of 
restrictions on transfer resulting from the Merger being accounted for as a 
pooling-of-interests in accordance with generally accepted principles and all 
published rules, regulations and policies of the SEC.

     SECTION 6.9 EMPLOYEE MATTERS.  HCCH agrees that all employees of Holdco 
or any Affiliated Company that remain employed after the Effective Time 
shall, within a reasonable time following the Effective Time, be entitled to 
receive the same benefits to which other employees of HCCH are entitled to 
receive and shall be entitled to participate in HCCH's Employee Benefit Plan 
provided such employees have satisfied the plan's eligibility requirements.

hereof, each of Holdco, the Affiliated Companies and HCCH agree that:

     SECTION 7.1 ADVICE OF CHANGES.  It will promptly advise the others in

                                      34

authorizations, approvals and consents.

     SECTION 7.3 ACTIONS CONTRARY TO STATED INTENT.  It shall not, from or 
after the date hereof and either before or after the Effective Time, take any

effected by the Merger from being accounted for as a pooling-of-interests 
under generally accepted accounting principles.  Each of HCCH, Holdco and the 
Affiliated Companies shall use its reasonable best efforts to cause its 
affiliates not to take any action that would preclude the ability of HCCH to 
account for the business combination to be effected by the Merger as a 
pooling-of-interests.

parties to any material contracts, in connection with the consummation of the 
transactions contemplated by this Agreement; and

HCCH will furnish any communication outside of their respective companies, if 
the subject matter thereof relates to the transactions contemplated by this 
Agreement and is not in the ordinary course of business, without the prior 
approval of the other of them as to the content thereof, which approval shall 
not be unreasonably withheld; provided that the foregoing shall not be deemed 
to prohibit any disclosure required by any applicable law or rule of the NYSE.

     SECTION 7.6 SATISFACTION OF CONDITIONS PRECEDENT.  HCCH, Holdco and each 
Affiliated Company will each use its reasonable best efforts to satisfy or 
cause to be satisfied all the conditions precedent that are applicable to

Material Adverse Effect or other breach of representation or warranty with 
respect to HCCH.

     (b)  HCCH shall have performed and complied with all of its covenants

<PAGE>

     (h)  Preston H. Smith, W. E. McDonough, David S. Folmar, Robert Scott 
and Albert H. Gilmore (the "Key Employees") shall receive such assurances, 
acceptable to each of the Key Employees and HCCH providing for a salary 
and/or severance payment to be made for the period ending December 31, 1998

Authorizations, permits, approvals and consents of securities or "blue sky" 
commissions of any jurisdiction and of any other governmental body or agency, 
that may reasonably be deemed necessary so that the consummation of the

which would have a Material Adverse Effect on HCCH, Holdco, any Affiliated 
Company or the Surviving Corporation, or would be reasonably likely to 
subject any of HCCH, Merger Sub, Holdco, any Affiliated Company or any of 
their respective directors or officers to penalties or criminal liability.

     (a)  By the mutual consent of the Boards of Directors of HCCH and Holdco.

     (b)  By the Board of Directors of either HCCH or Holdco if there has 
been a material breach by the other of any representation or warranty 
contained in this Agreement, which in either case cannot be, or has not been,

party committing such breach, provided that the right to effect such cure 
shall not extend beyond the date set forth in subparagraph (c) below.

     (c)  By the Board of Directors of either HCCH or Holdco if (i) all 
conditions of Closing required by Article VIII hereof have not been met or 
waived by June 30, 1997, or (ii) the Merger has not occurred by such date; 
provided, however, that neither HCCH nor Holdco, shall be entitled to 
terminate this Agreement pursuant to this subparagraph (c) if such party is 
in willful and material violation of any of its representations, warranties 
or covenants in this Agreement.

     (d)  If any governmental authority shall have issued an order, decree or 
ruling or taken any other action permanently enjoining, restraining or 
otherwise prohibiting the Merger and such order, decree, ruling or other 
action shall have become final and nonappealable.

     (e)  By the Board of Directors of HCCH, if Folmar shall have become

for damages, and all costs and expenses incurred in connection with the 
preparation, negotiation, execution and performance of this Agreement.

                                CLOSING MATTERS

     SECTION 10.1 THE CLOSING.  Subject to termination of this Agreement as 
provided in Article IX above, the closing of the transactions provided for 
herein (the "Closing") will take place at the offices of Winstead Sechrest & 
Minick P.C., 910 Travis Street, Suite 1700, Houston, Texas 77002 at 10:00 
a.m., Houston Time on April 30, 1997, or, if all conditions to Closing have 
not been satisfied or waived by such date, such other place, time and date as 
Holdco and HCCH may mutually select (the "Closing Date").  Prior to or 
concurrently with the Closing, the Agreement of Merger and such officers' 
certificates or other documents as may be required to effect the Merger will 
be filed in the office of the Secretary of the State of Texas.  Accordingly, 
the Merger will become effective at the Effective Time.

     SECTION 10.2 CONVERSION OF CERTIFICATES.

     (a)  As of the Effective Time, all shares of Holdco or any Affiliated 
Company Common Stock that are outstanding immediately prior thereto will, by 
virtue of the Merger and without further action, cease to exist, and all such 
shares of Holdco will be converted into the absolute and irrevocable right to 
receive from HCCH the number of shares of HCCH Common Stock determined as set 
forth in Article I hereof.

     (b)  At and after the Effective Time, each certificate representing 
outstanding shares of Holdco Common Stock will represent the number of shares 
of HCCH Common Stock into which such shares of Holdco Common Stock will be 
exchanged and will be deemed registered in the name of the holder of such 
certificate.  At the Effective Time, the holder of shares of Holdco Common 
Stock will surrender the certificates for such shares (the "Holdco 
Certificates") to HCCH for cancellation.  Promptly following the Effective 
Time and receipt of the Holdco Certificates, HCCH will cause its transfer 
agent to issue to such surrendering holder certificates for the number of 
shares of HCCH Common Stock to which such holder is entitled pursuant to the 
terms hereof.

     (c)  All shares of HCCH Common Stock delivered upon the surrender of 
Holdco Certificates in accordance with the terms hereof will be delivered to 
the registered holder.  After the Effective Time, there will be no further 
registration of transfers of the shares of Holdco Common Stock on the stock 
transfer books of Holdco or any Affiliated Company.  If, after the Effective 
Time, Holdco Certificates are presented for transfer or for any other reason, 
they will be canceled and exchanged and certificates therefor will be 
delivered as provided in this Section 10.2.

     (d)  Until Holdco Certificates representing Holdco Common Stock 
outstanding prior to the Merger are surrendered pursuant to this Section 
10.2, such certificates will be deemed, for all purposes, to evidence 
ownership of the number of whole shares of HCCH Common Stock into which the 
shares of Holdco Common Stock will have been converted pursuant to Section 
1.3.

                                  ARTICLE XI

                             INDEMNIFICATION AND
                      REMEDIES, CONTINUING COVENANTS

     SECTION 11.1 AGREEMENT TO INDEMNIFY.  Subject to the limitations set 
forth in this Article XI and except as set forth in Section 11.2, from and 
after the Effective Time each Shareholder, severally and Pro Rata (as 
hereinafter defined), will indemnify and hold harmless HCCH and its 
respective officers, directors, agents and employees, and each person, if 
any, who controls or may control HCCH within the meaning of the Securities 
Act (hereinafter in this Section 11.1 and in Section 11.2 below referred to 
individually as a "Holdco Indemnified Person" and collectively as "Holdco 
Indemnified Persons") from and against any and all claims, demands, actions, 
causes of action, losses, costs, damages, liabilities and expenses including, 
without limitation, reasonable legal fees, (net of:  (i) any recoveries under 
insurance policies; (ii) recoveries from third parties; and (iii) tax savings 
known to Holdco Indemnified Persons at the time of making of claims 
hereunder) made against or incurred by Holdco Indemnified Persons (hereafter 
in this Section 11.1 referred to as "HCCH Damages"), arising out of any 
misrepresentation or breach of or default under any of the representations, 
warranties, covenants or agreements given or made in this Agreement or any 
certificate or exhibit delivered by or on behalf of Holdco, any of the 
Affiliated Companies, or any of the Shareholders pursuant hereto.  "Pro Rata" 
for purposes of Sections 11.1 and 11.2 with respect to each Shareholder shall 
mean the proportion that such Shareholder's holdings of Holdco Common Stock 
as of immediately prior to the Effective Time bears to the total shares of 
Holdco Common Stock held by all Shareholders as of immediately prior to the 
Effective Time.  The indemnification provided for in this Section 11.1 will 
not apply unless and until the aggregate HCCH Damages for which one or more 
Holdco Indemnified Persons seeks indemnification exceeds $150,000 in the 
aggregate, in which event the indemnification provided for will include all 
HCCH Damages (a franchise deductible) up to the Maximum Shareholder Liability 
(as hereinafter defined).  The Holdco Indemnified Persons are only entitled 
to be reimbursed for the actual indemnified expenditures or damages incurred 
by them for the above described losses.  Such Holdco Indemnified Persons are 
not entitled to consequential, special, or other speculative or punitive 
categories of damages.  In seeking indemnification for HCCH Damages under 
this Section 11.1 following the Closing, the Holdco Indemnified Persons' 
remedy will be limited to receiving up to that number of shares of HCCH 
Common Stock determined by dividing (a) the amount of the HCCH Damages by (b) 
the closing sale price of HCCH's Common Stock on the New York Stock Exchange 
on the Effective Date (the "Closing Date Price"), provided, however, that 
irrespective as to the number of claims asserted by Holdco Indemnified 
Persons hereunder and the amount of the HCCH Damages for which 
indemnification is sought, any such Shareholder, in the aggregate, shall 
under no circumstances be required to make indemnification payments hereunder 
beyond the Closing Date Price multiplied by the number of shares of HCCH 
Common Stock received by such Shareholder at the time of the Merger (the 
"Maximum Shareholder Liability").  Notwithstanding anything to the contrary 
set forth herein, in the event that at the time of the resolution of any such

Common Stock (including any shares otherwise acquired at any time before or 
after the Effective Time or at any time after any claim is made for 
indemnification) necessary to settle any indemnification claim, then such 
Shareholder shall pay in cash or other immediately available funds the cash 
equivalent of the remainder of his in-stock indemnification obligations under 
this Section 11.1 up to his Maximum Shareholder Liability.  In lieu of HCCH 
Common Stock, any Shareholder shall have the option to pay in cash or other 
immediately available funds the cash equivalent of all or any part of his 
in-stock Maximum Shareholder Liability.

     SECTION 11.2 INDEMNIFICATION WITH RESPECT TO TAXES.  In addition to the 
indemnification provided in Section 11.1 above, each Shareholder, severally 
and Pro Rata hereby specifically agrees individually to indemnify and hold 
harmless the Indemnified Persons from and against all HCCH Damages, whenever 
incurred, arising out of any Taxes arising out of or relating to the business 
of Holdco or the Affiliated Companies prior to the Effective Time.

     SECTION 11.3 HCCH AGREEMENT TO INDEMNIFY.  Subject to the limitations 
set forth in this Article XI, from and after the Effective Time HCCH will 
indemnify and hold harmless Holdco, each Affiliated Company, and the Holdco 
Shareholders and their officers, shareholders, directors, administrators, 
heirs, personal representatives, successors and assigns (hereinafter in this 
Section 11.3 referred to individually as an "HCCH Indemnified Person" and 
collectively as "HCCH Indemnified Persons") from and against any and all 
claims, demands, actions, causes of action, losses, costs, damages, 
liabilities and expenses including, without limitation, reasonable legal fees 
(net of:  (i) any recoveries under insurance policies; (ii) recoveries from 
third parties; and (iii) tax savings known to HCCH Indemnified Persons at the 
time of making a claim hereunder) (hereafter in this Section 11.3 referred to 
as "Holdco Damages") arising out of any misrepresentation or breach of or 
default under any of the representations, warranties, covenants and 
agreements given or made by HCCH or Merger Sub in this Agreement or any 
certificate or exhibit delivered by or on behalf of HCCH or Merger Sub 
pursuant hereto.  In seeking indemnification for Holdco Damages under this 
Section 11.3 following the Closing, the HCCH Indemnified Person's remedy will 
be limited to receiving up to that number of shares of HCCH Common Stock 
determined by dividing (a) the amount of the Holdco Damages by (b) the 
Closing Date Price; provided, however, that irrespective of the number of 
claims asserted by HCCH Indemnified Persons hereunder in the amount of the 
Holdco Damages for which indemnification is sought, HCCH, in the aggregate, 
shall under no circumstances be obligated to make an indemnification payment 
hereunder beyond that number of shares of HCCH Common Stock equal to the 
total number of shares of HCCH Common Stock provided to the Holdco 
Shareholders on the Effective Date (the "Maximum HCCH Liability").  The 
indemnification provided for in this Section 11.3 will not apply unless and 
until the aggregate Holdco Damages for which one or more HCCH Indemnified 
Person seeks indemnification exceeds $150,000 in the aggregate, in which 
event the indemnification provided for will include all Holdco Damages (a 
franchise deductible) up to the Maximum HCCH Liability.  The HCCH Indemnified 
Persons are only entitled to be reimbursed for the actual indemnified 
expenditures or damages incurred by them for the above described losses.  
Such HCCH Indemnified Persons are not entitled to consequential, special, or 
other speculative or punitive categories of damages.

     SECTION 11.4 APPOINTMENT OF REPRESENTATIVE.  Subject to the 
successorship provisions of this Section 11.4, Folmar (the "Representative") 
is hereby irrevocably appointed as the attorney-in-fact and representative of 
the interests of the Shareholders for all purposes of this Agreement, and 
notice is hereby given thereof to HCCH and Merger Sub, and, without 
independent verification, HCCH and Merger Sub may rely upon Representative's 
undertakings in such capacity.  The Representative shall have full and 
irrevocable authority on behalf of the Shareholders, and shall promptly and 
completely exercise such authority in a timely fashion to:

     (a)  participate in, represent and bind the Shareholders in all respects 
with respect to any arbitration or legal proceeding relating to this 
Agreement, including, without limitation, the defense and settlement of any 
matter, and the calculation thereof for every purpose thereunder, consent to 
jurisdiction, enter into any settlement, and consent to entry of judgment, 
each with respect to any or all of the Shareholders;

     (b)  receive, accept and give notices and other communications relating 
to this Agreement;

     (c)  take any action that the Representative deems necessary or 
desirable in order to fully effectuate the transactions contemplated by this 
Agreement;

     (d)  execute and deliver any instrument or document that the 
Representative deems necessary or desirable in the exercise of his authority 
under this Section 11.4; and

     (e)  waive the fulfillment of any condition or conditions to the Closing.

     Those Shareholders who, as of the Effective Date, hold a majority of the 
Holdco Common Stock may, at any time and by written action delivered to HCCH, 
remove the Representative or any successor thereto, but such removal shall be 
effective only upon the replacement of such Representative or successor by a 
new Representative designated, by written notice delivered to HCCH, by those 
Shareholders who, as of the date hereof hold a majority of Holdco Common 
Stock, PROVIDED, however, that any such notice shall be effective upon actual 
receipt by HCCH.  Any such written notice shall be delivered to HCCH in 
accordance with the notice provisions set forth in Section 12.3 hereof.  If 
any Representative shall have died, become incapacitated or unable to serve, 
those Shareholders who, as of the date hereof, hold a majority of Holdco 
Common Stock shall promptly designate by written notice delivered to HCCH, a 
replacement Representative.  Any costs and expenses incurred by the 
Representative in connection with actions taken pursuant to or permitted by 
this Section 11.4 will be borne by the Shareholders and paid or reimbursed to 
the Representative Pro Rata.

     The foregoing authorization is granted and conferred in consideration 
for the various agreements and covenants of HCCH and Merger Sub contained 
herein.  In consideration of the foregoing, and subject to the successorship 
provisions of this Section 11.4, this authorization granted to the 
Representative shall be irrevocable and shall not be terminated by any act of 
any of the Shareholders or by operation of law, whether by death or 
incompetence of any Shareholder 

                                      44

<PAGE>

or by the occurrence of any other event except the termination of this 
Agreement pursuant to Section 9.1 hereof.  If after the execution hereof any 
such Shareholder shall die or become incompetent, the Representative is 
nevertheless authorized and directed to exercise the authority granted in 
this Section 11.4 as if such death or incompetence had not occurred and 
regardless of notice thereof.  The Representative shall have no liability to 
any Shareholder for any act or omission or obligation hereunder, provided 
that such action or omission is taken by the Representative in good faith and 
without willful misconduct.

     SECTION 11.5 SURVIVAL OF REPRESENTATIONS.  Unless the right to enforce 
the breach of any representation, warranty, covenant or agreement is required 
to terminate at an earlier time in order to maintain the appropriate 
pooling-of-interest accounting treatment, the right to enforce the breach of 
each representation, warranty, covenant and agreement set forth in this 
Agreement will remain operative and in full force and effect for a period of 
one year after the Closing (the last date of such applicable period of not 
more than one year being herein called the "Final Date"), regardless of any 
investigation made by or on behalf of the parties to this Agreement, upon 
which Final Date such representations, warranties, covenants and agreements 
shall expire and be of no further force and effect, except that the covenants 
set forth in the Confidentiality Agreement shall survive termination of this 
Agreement in accordance with the terms of such Confidentiality Agreement.  
The indemnification referred to and set forth in Section 11.2 shall survive 
until a final resolution of such claim is effective.  Any litigation or other 
action of any kind arising out of or attributable to a breach of any 
representation, warranty, covenant or agreement contained in this Agreement, 
except as set forth in Section 11.2, must be commenced prior to the Final 
Date.  If not so commenced prior to the Final Date, any claims or 
indemnifications brought under this Article XI will thereafter conclusively 
be deemed to be waived regardless of when such claim is or should have been 
discovered.  Any such claim for indemnification brought under this Article 
XI, brought before the Final Date, shall survive until a final resolution of 
such claim is effective.  As set forth herein, no investigation by any party 
hereto into the business, operations and conditions of the other party shall 
diminish in any way the effect of any representation or warranty made by any 
such party in this Agreement or shall relieve any party of any of its 
obligations under this Agreement.

     SECTION 11.6 PROCEDURE FOR INDEMNIFICATION; THIRD PARTY CLAIMS.  

     (a)  Promptly after receipt by an indemnified party under this Article 
XI of notice of a claim against it for indemnification brought under this 
Article XI (a "Claim"), the indemnified party will, if a claim is to be made 
against an indemnifying party, give prompt written notice to the indemnified 
party of the Claim, but the failure to promptly notify the indemnified party 
will not relieve the indemnified party of any liability that it may have to 
any indemnified party, except to the extent that the indemnifying party 
demonstrates that the defense of such action is prejudice by the indemnifying 
party's failure to give such prompt notice.  Such notice shall contain a 
description in reasonable detail of facts upon which such Claim is based and, 
to the extent known, the amount thereof.

                                      45

<PAGE>

     (b)  If any Claim referred to in this Article XI is made by a third 
party against an indemnified party and such indemnified party gives written 
notice to the indemnifying party of the Claim, the indemnifying party will be 
entitled to participate in the defense of Claim and, to the extent that it 
wishes to assume the defense of the Claim and, after written notice from the 
indemnifying party to the indemnified party of its election to assume the 
defense of the Claim, the indemnifying party shall assume such defense and 
will not be liable to the indemnified party under this Article XI for any 
fees of other counsel or any other expenses with respect to the defense of 
the Claim in each case subsequently incurred by the indemnified party in 
connection with the defense of the Claim.

                                  ARTICLE XII

                                 MISCELLANEOUS

     SECTION 12.1 FURTHER ASSURANCES.  Each  party  agrees  to  cooperate  
fully  with  the  other  parties  and  to execute such further instruments,

     SECTION 12.2 FEES AND EXPENSES.  Until otherwise agreed by the parties, 
each party shall bear its own fees and expenses, including counsel fees and

(irrespective of its choice of law principles) will govern the validity of 
this Agreement, the construction of its terms, and the interpretation and

Texas.

     SECTION 12.5 BINDING UPON SUCCESSORS AND ASSIGNS, ASSIGNMENT.  This 
Agreement and the provisions hereof shall be binding upon each of the 
parties, their permitted successors and assigns.  This Agreement may not be

HOWEVER, that HCCH shall be permitted at any time prior to the Effective Time

relieving HCCH of its obligations under this Agreement with respect to Merger 
Sub or the Merger).

<PAGE>

     SECTION 12.6 SEVERABILITY.  If any provision of this Agreement, or the 
application thereof, shall for any reason or to any extent be invalid or 
unenforceable, the remainder of this Agreement and application of such 
provision to other persons or circumstances shall continue in full force and 
effect and in no way be affected, impaired or invalidated.

     SECTION 12.7 ENTIRE AGREEMENT.  This Agreement, together with the 
Confidentiality Agreement, and any other agreement and instrument referenced 
herein constitute the entire understanding and agreement of the parties with 
respect to the subject matter hereof and supersede all prior and 
contemporaneous agreements or understandings, inducements or conditions, 
express or implied, written or oral, between parties with respect hereto.

     SECTION 12.8 AMENDMENT AND WAIVERS.  Any amendment or waiver affecting 
the Shareholders shall be valid if consented to in writing by Shareholders 
holding a majority of the shares of Holdco Common Stock (i) if given or made 
prior to the Effective Time, such majority as determined as of the date of 
such amendment or waiver, and (ii) if given or made at or after the Effective 
Time, such majority as determined immediately prior to the Effective Time.  
Any term or provision of this Agreement may be amended, and the observance of 
any term of this Agreement may be waived (either generally or in a particular 
instance and either retroactively or prospectively) only by a writing signed 
by those persons as provided in this Section 12.8.  The waiver by a party of 
any breach hereof or default in the performance hereof shall not be deemed to 
constitute a waiver of any other default or any succeeding breach or default, 
unless such waiver so expressly states.  At any time before the Effective 
Time, this Agreement may be amended or supplemented by Holdco, the Affiliated 
Companies, the Shareholders or HCCH with respect to any of the terms 
contained in this Agreement. 

     SECTION 12.9 NO WAIVER.  The failure of any party to enforce any of the

party thereafter to enforce such provisions.

     SECTION 12.10 CONSTRUCTION OF AGREEMENT.  A reference to an Article, 
Section or an Exhibit shall mean an Article of, a Section in, or Exhibit to, 
this Agreement unless otherwise explicitly set forth.  The titles and

     SECTION 12.11 COUNTERPARTS.  This Agreement may be executed in any 
number of counterparts, each of which shall be an original as against any
