the Common Stock (the "Common Stock") of HCC Insurance  Holdings,  Inc. ("HCCH")

Lockwood abstained from the HCCH's Board of Directors' consideration of and vote

by Mr. Lockwood in HCCH. Under the Plan of Reorganization, upon the consummation
of the Merger,  Mr.  Lockwood was elected to the office of the President of HCCH
and continues to serve as a member of the Board of Directors of HCCH.

shares of HCCH  Common  Stock  for each  share of his  56,764.848  shares of LDG
common stock,  or an aggregate of 3,941,565  shares of HCCH Common Stock.  Under
the Plan of  Reorganization,  upon consummation of the Merger,  Mr. Lockwood was

Agreement  pursuant  to which he has agreed not to dispose of his shares of HCCH
Common  Stock  received in the Merger  until HCCH  publicly  releases  its first

                      AGREEMENT AND PLAN OF REORGANIZATION


         THIS AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is entered
into as of the 22nd day of February,  1996 by and among HCC Insurance  Holdings,
Inc.,  a Delaware  corporation  ("HCCH"),  Merger  Sub,  Inc.,  a  Massachusetts
corporation and a wholly owned subsidiary of HCCH ("Merger Sub"), LDG Management
Company  Incorporated  ("LDG"),  a  Massachusetts  corporation,  SRRF Management
Incorporated   ("SRRF"),  a  Massachusetts   corporation,   Medical  Reinsurance
Underwriters Incorporated ("MRUI"), a Massachusetts  corporation,  LDG Worldwide
Limited  ("Worldwide"),   a  Delaware  corporation,  and  LDG  Insurance  Agency
Incorporated,  a Massachusetts  corporation ("LIAI"), (SRRF, MRUI, Worldwide and
LIAI  being  sometime   collectively  referred  to  herein  as  the  "Affiliated
Companies"),  Stephen J. Lockwood  ("Lockwood") and Walter L. Suydam ("Suydam"),
(Lockwood, Suydam and any person becoming a shareholder of LDG subsequent to the
date hereof and on or prior to the  Effective  Date who  executes a  counterpart
signature  page in the form  attached  hereto)  being  collectively  referred to
herein as the "LDG  Shareholders").  As of the  Effective  Date,  wherever  used
herein and in the LDG Disclosure  Schedule (as  hereinafter  defined),  the term
"Affiliated Companies" shall mean "Subsidiaries."

                                    RECITALS:

         A. The  Boards of  Directors  of each of HCCH,  Merger Sub and LDG have
determined to engage in the transaction  contemplated hereby,  pursuant to which
(i) prior to the Effective Date (as hereinafter defined), each of the Affiliated
Companies  shall  become  wholly owned  subsidiaries  of LDG  (sometimes  herein
collectively  called the  "Subsidiaries")  by means of the  contributions to the
capital of LDG by Lockwood  and Suydam of all the shares of Common  Stock of the
Affiliated  Companies held by them, (ii) Merger Sub will merge with and into LDG
(the  "Merger"),  (iii) the capital stock of Merger Sub shall be converted  into
shares of common stock of LDG (the "LDG Common  Stock");  and (iv) each share of
LDG Common Stock  outstanding  immediately  prior to the Effective Time 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 LDG and the  Affiliated  Companies  have
approved,  and the Board of Directors of LDG has resolved,  subject to the terms
of this  Agreement,  to recommend that  shareholders  of LDG 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,  and has  resolved  to  recommend  that
shareholders  of HCCH approve the issuance of HCCH's  Common Stock in connection
with the Merger.  HCCH, as the sole  shareholder of Merger Sub, has approved the
Merger, this Agreement and the Articles of Merger.

         D.  The  parties  intend  for  the  transactions  contemplated  by this
Agreement  to  qualify  as a plan  of  reorganization  in  accordance  with  the
provisions  of Section  368(a) of the Internal


                                       1


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 LDG in  accordance  with the laws of the  Commonwealth  of
Massachusetts  ("Massachusetts Law"), whereupon the separate existence of Merger
Sub shall cease,  and LDG 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, LDG 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
Commonwealth  of  Massachusetts,  and make all such other  filings or recordings
required by  Massachusetts  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 Commonwealth of Massachusetts, in accordance with
the relevant provisions of Massachusetts 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 LDG and Merger  Sub,  all as
provided under Massachusetts Law.

         SECTION 1.2       CONVERSION OF SHARES.

         (a)      At the Effective Time:

                  (i) 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.

                  (ii) each share of LDG Common  Stock  outstanding  immediately
         prior to the Effective Time shall  automatically and without any action
         on the  part of the  holder


                                       2


         thereof  cease to be  outstanding  and be  converted  into the right to
         receive  that number of shares of HCCH Common  Stock as is equal to the
         "Exchange  Ratio,"  which shall be  determined  in the manner  provided
         below.

         (b)      For purposes of this Agreement, the "Exchange Ratio" shall be
calculated as follows:

                  (i) if the Average HCCH Trading Price (as defined below) is at
         least $36.00 per share,  the Exchange Ratio shall equal the quotient of
         2,500,000  divided by 90,010 (the sum of all of the outstanding  shares
         of LDG Common Stock held by  shareholders  of LDG) or 27.775  shares of
         HCCH  Common  Stock  at the  Effective  Time.  Such  quotient  shall be
         multiplied by the shares of LDG Common Stock held by each holder of LDG
         Common Stock.  No fractional  shares shall be issued and each holder of
         LDG Common  Stock shall be entitled to the nearest  whole share of HCCH
         Common Stock rounded upwards or downwards  provided,  however,  that in
         the  aggregate  only  2,500,000  shares of HCCH  Common  Stock shall be
         issued pursuant to this clause (i); or

                  (ii) except as set forth in the proviso below,  if the Average
         HCCH Trading Price is less than $36.00,  the  shareholders of LDG shall
         be entitled to receive that number of shares of HCCH Common Stock equal
         to the  quotient of  $90,000,000  divided by the Average  HCCH  Trading
         Price,  and, after  determining the aggregate  number of shares of HCCH
         Common Stock to be issued hereunder,  the number of shares to be issued
         to each holder of LDG Common Stock shall be  determined as set forth in
         clause (i) above.

Provided,  if the Average  HCCH Trading  Price is less than $33.00,  LDG or HCCH
shall have the right to  terminate  this  Agreement  in the manner  provided  in
subsection  (c) below.  As used herein,  the term "Average  HCCH Trading  Price"
shall mean the  arithmetic  mean of each of the closing sale prices per share of
HCCH Common  Stock on the New York Stock  Exchange  (the "NYSE") for each of the
five (5) trading days ending on the fourth trading day immediately preceding the
scheduled date of the HCCH shareholder meeting  contemplated herein (such fourth
trading date being referred to herein as the "Determination Date").

         (c) In the event  that  either  party  shall  elect to  terminate  this
Agreement in the  circumstances  contemplated by subsection (b) above,  then the
party so electing  shall give notice of  termination of the other party prior to
12:00 midnight (Houston time) on or before the second trading date following the
Determination  Date.  Such  termination  shall become  effective  automatically,
without the action of either  party,  at 12:00  midnight  (Houston  time) on the
trading  day  immediately  preceding  the date of the HCCH  shareholder  meeting
contemplated herein.

         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.


                                       3


         (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 LDG Common  Stock  (other than for shares of LDG Common  Stock held by
any LDG Shareholder who has elected to accept  appraisal  rights as contemplated
by Section 1.5).

         (c) If  prior  to the  Merger,  HCCH  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 into  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  declares a
dividend on its outstanding  shares payable in shares or securities  convertible
into shares,  the number of shares of HCCH Common Stock into which the shares of
LDG Common Stock are to be converted, will be adjusted appropriately.

         SECTION  1.4  REGISTRATION  ON FORM S-4.  The HCCH  Common  Stock to be
issued in the Merger shall be registered  under the  Securities  Act of 1933, as
amended (the "Securities Act"), on a Form S-4 Registration Statement to be filed
by HCCH (as the same may be  amended  or  supplemented  from  time to time,  the
"Registration  Statement").  As promptly as  practicable  after the date of this
Agreement,  HCCH shall  prepare and file with the United States  Securities  and
Exchange   Commission   (the   "SEC")   a   prospectus/proxy    statement   (the
"Prospectus/Proxy Statement") and any other documents required by the Securities
Exchange Act of 1934, as amended (the "Exchange  Act"),  in connection  with the
Merger and the  Registration  Statement and any other documents  required by the
Securities  Act in  connection  with the Merger.  HCCH shall use all  reasonable
efforts  to  have  the  Registration  Statement  declared  effective  under  the
Securities Act.

         SECTION 1.5       DISSENTING SHARES.

         (a)  Notwithstanding  any provision of this  Agreement to the contrary,
the shares of any  holder of LDG Common  Stock who has  demanded  and  perfected
appraisal rights for such shares in accordance with  Massachusetts  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 Massachusetts Law.

         (b)  Notwithstanding the provisions of subsection (a), if any holder of
shares  of  LDG  Common  Stock  who  demands  appraisal  of  such  shares  under
Massachusetts Law shall effectively withdraw the right to appraisal, then, as of
the later of the  Effective  Time and the  occurrence  of such  event,  such LDG
Shareholder's  shares of LDG 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) LDG shall give HCCH (i) prompt  notice of any  written  demands for
appraisal of any shares of LDG Common Stock,  withdrawals  of such demands,  and
any other  instruments


                                       4


served  pursuant to  Massachusetts  Law and  received by LDG which relate to any
such  demand  for  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 Massachusetts Law.


                                   ARTICLE II

                            THE SURVIVING CORPORATION

         SECTION 2.1  ARTICLES  OF  ORGANIZATION.  At the  Effective  Time,  the
Articles of Organization of LDG as in effect  immediately prior to the Effective
Time, shall be the Articles of Organization of the Surviving Corporation.  Prior
to the  Effective  Date,  HCCH shall,  subject to Section  6.11,  propose  those
amendments  to the  Articles  of  Organization  as it deems  appropriate,  which
amendments shall be incorporated  into the Articles of Merger and Plan of Merger
associated therewith.

         SECTION  2.2 BYLAWS.  At the  Effective  Time,  the Bylaws of LDG as in
effect  immediately  prior to the  Effective  Time  shall be the  Bylaws  of the
Surviving  Corporation.  Prior to the  Effective  Date,  HCCH shall,  subject to
Section 6.11,  propose those amendments to such Bylaws as it deems  appropriate,
which amendments  shall be incorporated  into the Articles of Merger and Plan of
Merger associated therewith.

         SECTION 2.3 DIRECTORS AND OFFICERS.  From and after the Effective Time,
until  successors are duly elected or appointed and qualified in accordance with
applicable  law,  the  directors  and the initial  officers of Merger Sub at the
Effective  Time  shall  become  directors  and  the  officers  of the  Surviving
Corporation.  In  addition,  HCCH shall take all  necessary  action to cause (i)
Lockwood to be appointed to the Board of Directors  and President of each of the
Surviving  Corporation  and HCCH, and appointed  Chairman of the Board and Chief
Executive  Officer of the Surviving  Corporation and (ii) Suydam to be appointed
Executive  Vice President and Director of the Surviving  Corporation  and Senior
Vice President of HCCH, with, for any position not held prior thereto,  all such
appointments and designations to become effective as of the Effective Time.


                                   ARTICLE III

                      REPRESENTATIONS AND WARRANTIES OF LDG

         Except as contemplated by this Agreement,  and except as disclosed in a
document   referring   specifically  to  this  Agreement  (the  "LDG  Disclosure
Schedule")  which has been delivered to HCCH prior to the date hereof and except
as otherwise provided in the Registration Statement, each of LDG, the Affiliated
Companies,  and  each  of the LDG  Shareholders  (severally  and  not  jointly),
represents  and  warrants to HCCH as set forth  below (it being  agreed that the
disclosure  on the LDG  Disclosure  Schedule of the existence of any document or
fact or


                                       5


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 and it being further agreed that as of the Effective Date,  references
to Affiliated Companies shall be deemed to mean Subsidiaries of LDG):

         SECTION  3.1  CORPORATE  EXISTENCE  AND  POWER.  LDG  and  each  of the
Affiliated Companies is a corporation duly incorporated, validly existing and in
good  standing  under the laws of the state of its  incorporation,  and have all
corporate  powers  and  all  material  governmental  licenses,   authorizations,
consents and approvals (collectively, "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,
as hereinafter  defined, on LDG or such Affiliated Company.  LDG and each of the
Affiliated  Companies 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 LDG  or  such  Affiliated  Company.  For  purposes  of  this
Agreement,  a "Material  Adverse  Effect,"  with respect to any person or entity
(including  without limitation LDG and HCCH), means a material adverse effect on
the financial condition,  business,  properties,  assets, liabilities (including
contingent  liabilities),  or results of operations of such person or entity and
its  affiliated  companies and  subsidiaries  and/or parent  corporation  and/or
corporations  under the same stock  ownership,  taken as a whole;  and "Material
Adverse  Change"  means a change or a  development  that has a Material  Adverse
Effect.  LDG has delivered to HCCH true and complete copies of LDG's and each of
the  Affiliated   Companies'   Certificate  of   Incorporation  or  Articles  of
Organization, as the case may be, and Bylaws as currently in effect.

         SECTION 3.2       AUTHORIZATION.

         (a) The  execution,  delivery  and  performance  by LDG and each of the
Affiliated  Companies of this Agreement and, in the case of LDG, the Articles of
Merger, and the consummation by LDG and each of the Affiliated  Companies of the
transactions  contemplated  hereby and thereby  including  the  execution of the
Confidentiality Agreement (as hereinafter defined), are within LDG's and each of
the Affiliated  Companies' corporate powers and have been duly authorized by all
necessary  corporate  action,   excluding  approval  by  LDG's  shareholders  in
connection with the consummation of the Merger. This Agreement,  the Articles of
Merger, and the  Confidentiality  Agreement  constitute,  or upon execution will
constitute,  valid  and  binding  agreements  of LDG and each of the  Affiliated
Companies party thereto,  enforceable  against such agreeing party 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.

         (b) Each of the LDG  Shareholders,  severally,  represents and warrants
that he has full right,  power and authority to enter into this  Agreement,  the
Affiliates  Agreement to be entered into by him, and each other  agreement to be
entered into by him in connection with the


                                       6


transactions  contemplated  hereby  and  that  this  Agreement,  the  Affiliates
Agreement,  and such other agreements  contemplated  hereby constitute,  or upon
execution will constitute, valid and binding agreements of such LDG Shareholder,
enforceable  against him in accordance with their  respective  terms,  except as
such enforcement may be limited by bankruptcy,  insolvency or other similar laws
effecting  the  enforcement  of  creditors'   rights  generally  or  by  general
principles of equity.

         SECTION 3.3  GOVERNMENTAL  AUTHORIZATION.  The execution,  delivery and
performance by LDG and each of the Affiliated  Companies of this Agreement,  the
execution,  delivery  and  performance  by LDG of the Articles of Merger and the
Confidentiality  Agreement and the  consummation of the Merger by LDG require no
action by or in respect  of, or filing  with,  any  governmental  body,  agency,
official or authority other than:

         (a)      the  filing  of   Articles  of  Merger  in   accordance   with
Massachusetts Law;

         (b)      compliance   with   any   applicable   requirements   of   the
Hart-Scott-Rodino  Antitrust  Improvements  Act  of  1976,  as amended (the "HSR
Act");

         (c)      compliance with any applicable  requirements of the Securities
Act and the rules and regulations promulgated thereunder;

         (d)      compliance with any applicable  foreign or state securities or
"blue sky" laws;

         (e) compliance with any requirements of any Federal,  state, foreign or
other insurance or reinsurance or intermediaries or managing general agent laws,
including licensing or other related laws;

         (f)  compliance  with  applicable  foreign  or state  qualifying  to do
business  or  registration  laws  in  Georgia,  Kansas,  Maine,   Massachusetts,
Minnesota,  New York,  Pennsylvania,  the United  Kingdom,  and Colombia,  South
America; and

         (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 LDG, the Affiliated  Companies or
the Surviving  Corporation,  or (ii) would not materially  adversely  affect the
ability of LDG, each  Affiliated  Company,  HCCH or Merger Sub to consummate the
transactions  contemplated  hereby and operate  their  businesses  as heretofore
operated.

         SECTION 3.4 NON-CONTRAVENTION.  The execution, delivery and performance
by LDG and each of the Affiliated  Companies of this  Agreement,  the execution,
delivery and  performance by LDG of the Articles of Merger and the  consummation
by LDG and each of the  Affiliated  Companies of the  transactions  contemplated
hereby and thereby do not and will not:

         (a) contravene or conflict with each such company's charter or bylaws;


                                       7


         (b) assuming compliance with the matters referred to in Section 3.3 and
assuming  the  requisite  approval  of  the  LDG  Shareholders  of  the  Merger,
contravene  or conflict  with or  constitute a violation of any provision of any
law,  regulation,   judgment,  injunction,  order  or  decree  binding  upon  or

in accordance with its normal accounting  practices and procedures  accruals and

The LDG Disclosure  Schedule sets forth those tax returns of LDG and each of the
Affiliated  Companies  (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

Neither  LDG,  nor  any  of  the  Affiliated   Companies  nor  any   predecessor

         (d) Each of LDG and each of the  Affiliated  Companies has maintained a

         SECTION 3.13      EMPLOYEE BENEFIT PLANS, ERISA.

         (a) To the  knowledge  of LDG,  each  Affiliated  Company,  Lockwood or
Suydam,  neither LDG nor any of the Affiliated  Companies is a party to any oral
or written  (i)  employment,  severance,  collective  bargaining  or  consulting
agreement not  terminable on 60 days' or less notice,  (ii)  agreement  with any
executive  officer  or  other  key  employee  of LDG  or  any of the  Affiliated
Companies  (A) the benefits of which are  contingent,  or the terms of which are
materially altered, upon the occurrence of a transaction involving LDG or any of
the


                                       13


Affiliated  Companies of the nature of any of the  transactions  contemplated by
this Agreement,  (B) providing any term of employment or compensation  guarantee
extending for a period longer than one year, or (C) providing severance benefits
or other benefits after the termination of employment of such executive  officer
or key employee regardless of the reason for such termination of employment,  or

stock appreciation right plan, restricted stock plan or stock purchase plan, the
benefits of which would be  increased,  or the vesting of benefits of which will
be  accelerated,  by the occurrence of any of the  transactions  contemplated by
this  Agreement or the value of any of the benefits of which will be  calculated
on the basis of any of the transactions contemplated by this Agreement.

         (b) Neither LDG, 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 LDG or any
Affiliated Company (an "LDG 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 LDG  Disclosure  Schedule  (which Plans have been
heretofore  delivered to HCCH) and maintained by LDG 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) To the knowledge of LDG, or any Affiliated Company, 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 LDG, or any  Affiliated
Company,  or any LDG ERISA  Affiliate  has occurred  with respect to any Pension
Plan or Welfare Plan. Each of LDG, each Affiliated  Company,  Lockwood or Suydam
has no knowledge of any breach of fiduciary responsibility under Part 4 of Title
I of ERISA which has resulted in liability of LDG, any Affiliated  Company,  and
LDG ERISA Affiliate, any trustee, administrator or fiduciary of any Pension Plan
or Welfare Plan.

         (e) Neither LDG, any Affiliated  Company,  nor any LDG 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 LDG, any Affiliated  Company,  nor any LDG
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



                                       14


demand payment of any  withdrawal  liability with respect to LDG, any Affiliated
Company, or any LDG ERISA Affiliate.

         (f) No  representation or warranty is given under Article III as to the
application  of Section  4999 of the Code or Sections  162(a)(1)  or 280G of the
Code.

         (g) With  respect to LDG,  each  Affiliated  Company and each LDG ERISA
Affiliate,  the LDG  Disclosure  Schedule  correctly  identifies  each  material
agreement,  policy, plan or other arrangement,  whether written or oral, express
or implied, fixed or contingent,  to which LDG is a party or by which LDG or any
property  or asset of LDG 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 LDG, any Affiliated  Company,  nor any LDG 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.  LDG and
each Affiliated  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 LDG 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 3.14      MATERIAL AGREEMENTS.

         (a) The LDG Disclosure  Schedule  (other than LDG Property  Leases,  as
hereinafter  defined),  includes a complete and accurate list of all  contracts,
agreements,  leases  and  instruments  to  which  LDG 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 LDG 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 LDG Agreements").

         (b) Neither LDG nor any Affiliated Company nor, to the knowledge of LDG
nor any Affiliated Company, any other party is in default under any Material LDG
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  LDG  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 LDG or any Affiliated
Company,  which,  in any such case,  has had or would  reasonably be expected to
have a Material Adverse Effect.



                                       15


         (c) To the  knowledge  of LDG and each  Affiliated  Company,  each such
Material  LDG  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 LDG Agreement.  No party to a Material LDG Agreement has advised
LDG that it intends either to terminate a Material LDG Agreement or to refuse to
renew a Material LDG Agreement upon the expiration of the term thereof.

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

         SECTION  3.15  PROPERTIES.  To the  knowledge  of LDG  and  each of the
Affiliated Companies, LDG or the Affiliated Company owns no real estate, and all
leases of real  property to which LDG or any of the  Affiliated  Companies  is a
party or by which it is bound  ("LDG  Property  Leases")  are in full  force and
effect. To the knowledge of LDG, there exists no default under such LDG 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 on LDG. All of the  properties and assets which are owned by LDG 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

to consummate the transactions  contemplated hereby and operate their businesses
as heretofore operated.

         SECTION 4.4 NON-CONTRAVENTION.  The execution, delivery and performance

Agreement.

         SECTION 4.7       SUBSIDIARIES.

         (a) Each Subsidiary of HCCH 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  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, 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

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.

         SECTION 4.8       SEC FILINGS.

         (a) HCCH has since October 28, 1992 filed all forms,  proxy statements,

         (b) HCCH has delivered, and will promptly deliver in the case of any of

         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  referred  to in  this  Section  4.8 as
amended or supplemented, if applicable, filed pursuant to the Securities Act, as

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

sheet of HCCH as of September  30,  1995,  and the notes  thereto,  contained in
HCCH's  quarterly  report on Form 10-Q filed for its fiscal  quarter then ended,
and "HCCH Balance Sheet Date" means September 30, 1995.

         SECTION  4.10  DISCLOSURE  DOCUMENTS.  None of the written  information
supplied or to be supplied  by HCCH or Merger Sub for  inclusion  in and that is
actually  included  in  the  Prospectus/Proxy  Statement  and  the  Registration
Statement,  will, in the case of the Prospectus/Proxy  Statement, at the time of
mailing of the  Prospectus/Proxy  Statement to  shareholders



                                       22

connection with the Merger,  contain any untrue  statement of a material fact or
omits or will omit to state any material fact  required to be stated  therein or
necessary in order to make the statements therein, in light of the circumstances
under  which  they  are  made,  not  misleading  or  will,  in the  case  of the
Registration Statement, at the time the Registration Statement becomes effective
under the Securities Act and at the Effective Time, contain any untrue statement
of a material  fact or omit to state any  material  fact  required  to be stated
therein  or  necessary  to  make  the  statements   therein,  in  light  of  the
circumstances  in  which  they  were  made,  not  misleading.  The  Registration

respects  with  the   provisions  of  the   Securities  Act  and  Exchange  Act,
respectively,   and  the  rules  and  regulations  thereunder,  except  that  no
representation or warranty is made by HCCH with respect to information  supplied
by LDG, any of the Affiliated  Companies,  or the LDG Shareholders for inclusion
therein.

         SECTION 4.11 ABSENCE OF CERTAIN  CHANGES.  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; or

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

         SECTION 4.12 NO  UNDISCLOSED  LIABILITIES.  There are no liabilities of

         (a)  liabilities  disclosed or provided  for in the HCCH Balance  Sheet
(including the notes thereto);

         (b) liabilities  incurred in the ordinary course of business consistent

         SECTION 4.13 LITIGATION. Other than actions, suits, proceedings, claims
or  investigations  occurring  in the  ordinary  course  of  business  involving

HCCH,  overtly  threatened,  against HCCH or any of its  Subsidiaries  or any of
their assets or against or involving any of its officers, directors or employees
in  connection  with  the


                                       23


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.  HCCH is not  subject to or in  default  with
respect  to any  writ,  order,  judgment,  injunction  or  decree  which  could,
individually or in the aggregate, have a Material Adverse Effect on HCCH.

         SECTION 4.14      TAXES.

         (a) HCCH and each of its  Subsidiaries  (i) has filed when due  (taking

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 or any of the Material HCCH Subsidiaries 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

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

(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

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 4.15      EMPLOYEE BENEFIT PLANS; ERISA.

         (a)  Neither  HCCH nor any  corporation  or other  entity  which  under

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


                                       24


HCCH) 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 Section 412 of the Code.  HCCH has made available to
LDG,  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 4.16      MATERIAL AGREEMENTS.

         (a) The HCCH Disclosure Schedule, together with the public filings made
by HCCH with the SEC (other than HCCH Property Leases, as hereinafter  defined),
includes a complete and accurate list of all contracts,  agreements,  leases 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 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
HCCH,  whether written or oral, but exclusive of 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 nor any  Subsidiary of HCCH,  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 Material HCCH Subsidiary is not
in violation of, or in default with respect to, any term of its  Certificate  of
Incorporation or Bylaws.

         SECTION 4.17  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 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 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 4.17, 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 on HCCH.



                                       26


         SECTION 4.18      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 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 4.19 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 4.20 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  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 4.21 TRADEMARKS,  TRADENAMES,  ETC. HCCH owns or possesses,  or
possesses 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 4.22 OPINION OF FINANCIAL ADVISOR. HCCH will retain at its sole
expense William Blair & Company,  L.L.C. to provide an opinion as to whether, as
of the date the  Prospectus/Proxy  Statement  is mailed and as of the  Effective
Date,  the  Exchange  Ratio  is fair,  from a  financial  point of view,  to the
shareholders of HCCH.

         SECTION  4.23  BROKER'S  FEES.  Except  as set forth in  Section  4.22,
neither HCCH nor Merger Sub, nor anyone acting on any of their behalves have 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.

file,  or join in the  execution  and  filing,  with  any  application  or other

Corporation.

         (e) If LDG's and/or any Affiliated  Company's  basis on which taxes are
computed are adjusted by any local,  state or Federal taxing  authority and such
adjustment   results  in  additional  tax   liabilities   to  LDG   Shareholders
("Taxpayers")  while LDG or any of its Affiliated  Companies were a Subchapter S
Corporation,   HCCH  agrees  to  reimburse  those  Taxpayers  if  the  following
conditions exist:

                           (1)      such  adjustments are of a nature that arise
                                    from changes in tax accounting  methods that
                                    are required to be adopted by LDG and/or any
                                    of its Affiliated Companies, and/or

                           (2)      such adjustments are of a nature that shifts
                                    an item of  deduction  from tax year 1995 or
                                    prior to tax  year  1996 or  thereafter,  or
                                    shifts  an  item of  income  from  1996  and
                                    thereafter to 1995 and prior.

         (f) If any local,  state or Federal taxing authority  adjusts the basis
on which taxes are  computed on HCCH's  income that  results in  additional  tax
liabilities  to HCCH,  the  Taxpayers  agree to reimburse  HCCH if the following
conditions exist:

                  (i)      the  adjustments  must  pertain  to LDG's  and/or any
                           Affiliated Company's taxable income and for tax years
                           1996  and  subsequent,  and  either  or  both  of the
                           following conditions must exist:

                           (1)      such  adjustments are of a nature that arise
                                    from changes in tax accounting  methods that
                                    are required to be adopted by HCCH, and/or

                           (2)      such adjustments are of a nature that shifts
                                    an item of  income  from  tax  year  1995 or
                                    prior to tax  year  1996 or  thereafter,  or
                                    shifts  an item of  deduction  from 1996 and
                                    thereafter to 1995 and prior.

tax purposes as a tax-free  reorganization  within the meaning of Section 368 of
the Code.  In  preparing  such  opinion,  counsel may rely on (and to the extent
reasonably  required,  the parties and LDG's shareholders shall make) reasonable
representations as to facts related thereto.

         (e) The LDG Shareholders  shall have received from Winstead  Sechrest &
Minick P.C.,  counsel to HCCH, an opinion in form and substance  satisfactory to
LDG's shareholders.



                                       41

         SECTION 8.3  CONDITIONS TO  OBLIGATIONS  OF EACH PARTY.  The respective
obligations of the parties  hereunder are subject to the fulfillment,  on and as
of the Effective  Date, of each of the following  conditions (any one or more of
which  may be  waived  by such  parties,  but only in a  writing  signed by such
parties):

         (a) HCCH's  shareholders  shall have duly approved the issuance of HCCH
Common  Stock in  connection  with the  Merger,  and  HCCH's  and LDG's and each
Affiliated Company's  shareholders shall have duly approved this Agreement,  the
Articles of Merger and the Merger,  all in accordance  with  applicable laws and
regulatory requirements.

         (b) The  Registration  Statement shall have become  effective under the
Securities  Act and shall not be the  subject of any stop  order or  proceedings
seeking a stop order, and the Prospectus/Proxy  Statement shall on the Effective
Date not be subject to any proceedings commenced or threatened by the SEC.

         (c) HCCH,  LDG and the LDG  Shareholders  shall have received a written
report  addressed  to  each  of them  from  Coopers  &  Lybrand  L.L.P.  in form

accordance  with  Statement of Auditing  Standards  No. 50), on the  appropriate
application  of  generally  accepted  accounting   principles  to  the  business
combination to be effected by the Merger.

         (d) No statute, rule, regulation,  executive order, decree,  injunction
or restraining  order shall have been enacted,  promulgated or enforced (and not
repealed,   superseded  or  otherwise  made   inapplicable)   by  any  court  or

party agreeing to use its reasonable best efforts to have any such order, decree
or injunction lifted).

         (e)  There  shall  have  been   obtained   any  and  all   Governmental
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 Merger
will be in compliance  with  applicable  laws,  the failure to comply with which
would have a Material Adverse Effect on HCCH, LDG, any Affiliated Company or the
Surviving  Corporations,  or would be reasonably  likely to subject any of HCCH,
Merger Sub, LDG, any Affiliated Company or any of their respective  directors or
officers to substantial penalties or criminal liability.



                                       42


         (f) The waiting  period (and any extension  thereof)  applicable to the

         SECTION 8.4       EFFECT OF FAILURE TO MEET CONDITIONS TO MERGER.

         (a) If there is a failure to meet the  conditions set forth in Sections

8.1(n),  or  8.1(o)  known to HCCH  prior to the  Effective  Date,  the sole and
exclusive remedy of HCCH shall be to terminate this Agreement and not consummate
the Merger with no liability to it or to LDG or its Affiliated  Companies or any
of the LDG  Shareholders  (even  if such  failure  to meet  any  such  condition
involves a breach of any representation, warranty, agreement or covenant) or, in
the alternative, HCCH shall be deemed to waive such failure and shall consummate
the Merger with no liability to LDG, any of its  Affiliated  Companies or any of
the LDG  Shareholders  with respect to or as a result of such  failure  (even if
such failure to meet any such condition involves a breach of any representation,
warranty, agreement or covenant).

         (b) If there is a failure to meet the  conditions set forth in Sections
8.2(c),  8.2(d) or 8.2(e) known to LDG prior to the Effective Date, the sole and
exclusive  remedy of LDG shall be to terminate this Agreement and not consummate
the Merger with no liability to it, its  Affiliated  Companies or any of the LDG
Shareholders  or to HCCH  (even  if such  failure  to meet  any  such  condition
involves a breach of any representation, warranty, agreement or covenant) or, in
the alternative,  LDG shall be deemed to waive such failure and shall consummate
the  Merger  with no  liability  to HCCH with  respect to or as a result of such
failure  (even if such failure to meet any such  condition  involves a breach of
any representation, warranty, agreement or covenant).

         (c) If there is a failure to meet the  conditions  set forth in Section
8.3, the sole and  exclusive  remedy of HCCH or LDG shall be to  terminate  this
Agreement and not consummate the Merger with no liability to any party hereunder
(even if such  failure  to meet  any such  condition  involves  a breach  of any
representation,  warranty,  agreement or covenant) or, in the  alternative,  the
parties to this  Agreement may waive such failure and consummate the Merger with
no  liability  to any party  hereunder  with  respect  to or as a result of such
failure  (even if such failure to meet any such  condition  involves a breach of
any representation, warranty, agreement or covenant).


                                   ARTICLE IX

                            TERMINATION OF AGREEMENT

         SECTION  9.1  TERMINATION.  In  addition  to those  termination  rights
provided for in Sections 1.2(b) hereof,  this Agreement may be terminated at any
time prior to the Effective Time (with respect to Section 9.1(b) through 9.1(h),
by written notice by the terminating  party to the other parties) whether before
or after the approval by the shareholders of LDG or HCCH:


                                       43


         (a) by mutual  consent of the Boards of Directors of HCCH,  Merger Sub,
and LDG;

         (b) by HCCH or LDG, if the Effective Date shall not have occurred on or
before  June 30,  1996;  provided  that the right to  terminate  this  Agreement
pursuant to this  clause (b) shall not be  available  to any party whose  wilful
failure to fulfill any obligation  under this Agreement has been the significant
cause of, or  resulted  in,  the  failure of the  Effective  Date to occur on or
before such date,  except that this proviso  shall not apply in the event any of
the closing conditions  enumerated in Section 8.4(a),  8.4(b), or 8.4(c) has not
been met (even if the failure of any such  condition to be met involves a breach
of any representation, warranty, agreement or covenant);

         (c) by HCCH or LDG, if, at the meeting of HCCH shareholders  (including
any  adjournment or  postponement  thereof) called pursuant to Section 6.2(b) of
this  Agreement,  the requisite vote of shareholders of HCCH shall not have been
obtained;

         (d) by HCCH, if it is not in material breach of its  obligations  under
this  Agreement  and if the Board of Directors  of LDG or any of the  Affiliated
Companies shall have withdrawn or adversely  modified its  recommendation of the
Merger;

         (e) by HCCH, if it is not in material breach of its  obligations  under
this Agreement, and if (i) there has been a breach by LDG, any of the Affiliated
Companies,  or any of the LDG  Shareholders  or any of its  representations  and
warranties  hereunder  such that  Section  8.1(a) will not be  satisfied or (ii)
there  has been a  material  breach  on the part of LDG,  any of the  Affiliated
Companies,  or any of the LDG  Shareholders  of any of its or his  covenants  or
agreements  contained in this  Agreement  such that  Section  8.1(b) will not be
satisfied,  and,  in both  case  (i) and case  (ii),  such  breach  has not been
promptly cured after notice to LDG;

         (f) by LDG, if it is not in  material  breach of its  obligation  under
this Agreement,  and if (i) there has been a breach by HCCH or Merger Sub of any
of their respective  representations and warranties  hereunder such that Section
8.2(a)  will not be  satisfied  or (ii) there has been a material  breach on the
part of HCCH or Merger Sub of any of their  respective  covenants or  agreements
contained in this Agreement such that Section 8.2(b) will not be satisfied, and,
in both case (i) and case (ii),  such breach has not been  promptly  cured after
notice to HCCH and Merger Sub;

         (g) by HCCH if either  Lockwood or Suydam shall have become Disabled or
died; or

         (h) By either  party,  if a permanent  injunction or other order of any
federal or state  court  which  would  make  illegal or  otherwise  restrain  or
prohibit  the  consummation  of the Merger  will have been  issued and will have
become final and non-appealable.  Notwithstanding the foregoing, if a temporary,
preliminary or permanent injunction or other order by any federal or state court
which would prohibit or otherwise restrain  consummation of the Merger will have
been issued and will remain in effect on the Closing Date,  and such  injunction
will not have become final and non-appealable, either party, by giving the other
written  notice  thereof  on or


                                       44


prior to such date, may extend the time for consummation of the Merger up to and
including  the earlier of the date such  injunction  will  become  final and non
appealable  or sixty days after the proposed  Closing Date so long as such party
will, at its own expense use its best efforts to have such injunction dissolved.

         SECTION 9.2 EFFECT OF TERMINATION.  In the event of termination of this
Agreement  by either  HCCH or LDG as provided  in Section  1.2(b),  9.1 or 12.12
hereof,  this  Agreement  shall  forthwith  become  void and  there  shall be no
liability on the part of HCCH, Merger Sub, LDG, any Affiliated  Company,  any of
the LDG Shareholders or their respective officers or directors.  In the event of
any other  termination  of this  Agreement,  there shall be no  liability of any
party,  except for the  liability  of any party  then in  willful  breach of its
obligations  under  this  Agreement  and  except  for any  breach  of a  party's
obligations under the Confidentiality Agreement (except that no party shall have
any liability in the event of any failure to meet any of the closing  conditions
enumerated in Section 8.4(a), 8.4(b), or 8.4(c) (even if such failure involves a
breach of any representation, warranty, agreement or covenant)).


                                    ARTICLE X

                                 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 the date of the HCCH Shareholders Meeting, or, if all conditions
to Closing  have not been  satisfied  or waived by such date,  such other place,
time and date as LDG 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 effectuate the Merger will
be filed in the office of the Secretary of the  Commonwealth  of  Massachusetts.
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 LDG 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  will be  converted  into the right to  receive  from HCCH the  number of
shares of HCCH Common Stock determined as set forth in Section 1.2 hereof.

         (b) At and after the  Effective  Time,  each  certificate  representing
outstanding  shares of LDG Common Stock will  represent  the number of shares of
HCCH  Common  Stock  into  which  such  shares  of LDG  Common  Stock  have been
converted, and such shares of HCCH Common Stock will be deemed registered in the
name of the  holder  of such  certificate.  As soon  as


                                       45


practicable  after the Effective  Time, the holder of shares of LDG Common Stock
will surrender the certificates for such shares (the "LDG Certificates") to HCCH
for cancellation.  Promptly  following the Effective Time and receipt of the LDG
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 LDG
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 LDG  Common  Stock on the  stock
transfer  books of LDG. If,  after the  Effective  Time,  LDG  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 LDG Certificates  representing  LDG 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 shares of HCCH Common  Stock into which the shares of LDG Common Stock
will have been converted.


                                   ARTICLE XI

                SURVIVAL OF REPRESENTATIONS, INDEMNIFICATION AND
                         REMEDIES, CONTINUING COVENANTS

         SECTION 11.1 SURVIVAL OF  REPRESENTATIONS.  Unless any  representation,
warranty,  covenant or  agreement is required to terminate at an earlier time in
order to maintain the appropriate pooling of interests accounting treatment, all
representations,   warranties,   covenants  and  agreements  contained  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 Section
6.11  and  the  Confidentiality  Agreement  shall  survive  termination  of this
Agreement  in   accordance   with  the  terms  of  such  Section  6.11  and  the
Confidentiality Agreement. Any litigation or other action of any kind (except by
the LDG Shareholders to the extent permitted by Section 6.11) arising out of, or
attributable to, a breach of any representation, warranty, covenant or agreement
contained in this Agreement must be commenced prior to the Final Date. Except as
provided in the  preceding  sentence  with  respect to Section  6.11,  if not so
commenced prior to the Final Date, any claim for  indemnification  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 effected.  As set forth
herein,  no investigation by any party hereto into the business,  operations and
conditions  of the other  parties  shall  diminish  in any way the effect of any
representation or warranty made by any



                                       46


such  party  in  this  Agreement  or  shall  relieve  any  party  of  any of its
obligations under this Agreement.

         SECTION  11.2  LDG  ET  AL.  AGREEMENT  TO  INDEMNIFY.  Subject  to the
limitations  set forth in this Article XI, each LDG  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 11.2 referred to  individually  as an "Indemnified
Person" and collectively as "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 any
recoveries  under  insurance  policies,  recoveries  from third  parties and tax
savings  known to HCCH at the time of making of claim  hereunder  (hereafter  in
this  Section  11.2  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 LDG, any of the Affiliated
Companies,  or any of the LDG Shareholders pursuant hereto. HCCH, Merger Sub and
such other  Indemnified  Persons  shall  take  reasonable  steps to obtain  such
recoveries  under  insurance  policies,  recoveries  from third  parties and tax
savings.  HCCH shall assign to the Representative any choses in action that HCCH
may have  against  third  parties  (other than choses in action  against the LDG
Shareholders  solely by reason of their status as LDG Shareholders) with respect
to  specific  claims as to which  HCCH,  Merger  Sub or such  other  Indemnified
Parties  have  received  indemnification  hereunder.  "Pro Rata" for purposes of
Sections  11.2 and 11.6 with  respect  to each LDG  Shareholder  shall  mean the
proportion  that  such LDG  Shareholder's  holdings  of LDG  Common  Stock as of
immediately  prior to the Effective Time bears to the total shares of LDG Common
Stock held by all LDG  Shareholders  as of  immediately  prior to the  Effective
Time.  The  indemnification  provided  for in this  Section  11.2 will not apply
unless and until the  aggregate  HCCH Damages for which one or more  Indemnified
Persons  seeks  indemnification  exceeds  $750,000  in the  aggregate  (the "LDG
Basket"), in which event the indemnification  provided for will include all HCCH
Damages (a franchise deductible) up to the Maximum LDG Shareholder Liability (as
hereinafter  defined).  In seeking  indemnification  for HCCH Damages under this
Section 11.2  following the Closing,  the  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  Indemnified  Persons  hereunder  and the amount of the HCCH
Damages for which  indemnification is sought,  any such LDG 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 LDG  Shareholder at the time of the
Merger (the "Maximum LDG Shareholder  Liability").  Notwithstanding  anything to
the contrary set forth herein,  in the event that at the time of the  resolution
of any such indemnification claim, such LDG Shareholder does not hold the number
of shares of HCCH 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
LDG Shareholder shall


                                       47


pay in cash or other  immediately  available  funds the cash  equivalent  of the
remainder of his in-stock indemnification obligations under this Section 11.2 up
to his Maximum LDG Shareholder Liability.  In lieu of HCCH Common Stock, any LDG
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  LDG
Shareholder Liability.

         SECTION 11.3 HCCH  AGREEMENT TO INDEMNIFY.  Subject to the  limitations
set forth in this Article XI, HCCH will  indemnify  and hold  harmless LDG, each
Affiliated Company,  and the LDG Shareholders and their officers,  shareholders,
directors,  administrators,  successors and assigns (hereinafter in this Section
11.3 referred to  individually as an  "Indemnified  Person" and  collectively as
"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 any recoveries under insurance
policies,  recoveries  from third parties and tax savings  known to  Indemnified
Persons at the time of making of claim hereunder (hereafter in this Section 11.3
referred to as "LDG 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.  The  indemnification  provided  for in this Section 11.3 will not apply
unless and until the  aggregate  LDG Damages  for which one or more  Indemnified
Persons  seeks  indemnification  exceeds  $750,000 in the  aggregate  (the "HCCH
Basket"),  in which event the indemnification  provided for will include all LDG
Damages  (a  franchise   deductible)  up  to  the  Maximum  HCCH  Liability  (as
hereinafter  defined).  In seeking  indemnification  for LDG Damages  under this
Section 11.3  following the Closing,  the  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 LDG  Damages by (b) the  Closing  Date Price.
Provided,  however,  that  irrespective  of the  number  of claims  asserted  by
Indemnified  Persons  hereunder  and the  amount  of the LDG  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 LDG  Shareholders on the Effective Date (the "Maximum HCCH
Liability").

         SECTION 11.4 EXCLUSIVE REMEDY. Notwithstanding anything in this Article
XI or elsewhere in this Agreement to the contrary,  the termination provision of
Section 1.2(b), Article IX and Section 12.12 and the indemnification  provisions
of this Article XI shall be the sole and exclusive remedy available to any party
or any other Indemnified  Person for any breach of any of HCCH's,  Merger Sub's,
LDG's,  any  Affiliated  Company's  and any LDG  Shareholder's  representations,
warranties,  covenants  or other  agreements  or  provisions  contained  in this
Agreement  or in any exhibit to this  Agreement  or  certificate  or  disclosure
schedule  delivered  pursuant to this Agreement or otherwise in connection  with
this Agreement and the transactions contemplated hereby, or any causes of action
related to any of the foregoing.



                                       48


         SECTION 11.5      PROCEDURE FOR INDEMNIFICATION; THIRD PARTY CLAIMS.

         (a) Promptly after receipt by an  indemnified  party under Section 11.2
or 11.3 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 under such Section,  give prompt written notice to
the  indemnifying  party of the Claim,  but the failure to  promptly  notify the
indemnifying party will not relieve the indemnifying 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  prejudiced  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.

         (b) If any Claim  referred  to in  Section  11.5(a)  is made by a third
party  against  an  indemnified  party  and  it  gives  written  notice  to  the
indemnifying  party of the Claim,  the  indemnifying  party will be  entitled to
participate  in the  defense of the 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 such Section 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.

         SECTION   11.6   APPOINTMENT   OF   REPRESENTATIVE.   Subject   to  the
successorship  provisions  of  this  Section  11.6,  Stephen  J.  Lockwood  (the
"Representative")  is hereby irrevocably  appointed as the  attorney-in-fact and
representative  of the  interests  of the  holders of LDG  Common  Stock 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  holders  of LDG  Common
Stock,  and shall  promptly and  completely  exercise such authority in a timely
fashion to:

         (a)  participate  in,  represent and bind the LDG  Shareholders  in all
respects with respect to any  arbitration or legal  proceeding  relating to this
Agreement,   including   without   limitation,   all  matters  relating  to  any
indemnification  under this Section  11.6,  taking any action under Section 11.5
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 holders of LDG Common Stock;

         (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;



                                       49


         (d)  execute  and  deliver  any   instrument   or  document   that  the
Representative  deems  necessary or  desirable in the exercise of his  authority
under this Section 11.6; and

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

         Those LDG Shareholders  (including without limitation  Lockwood and any
of his assigns who are members of his immediate family) who, as of the Effective
Date,  hold a majority  of the LDG 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 the holders of a majority  of LDG Common  Stock,
including Lockwood's LDG 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  holders of LDG Common Stock who, as of the date hereof,
hold a majority thereof, 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 11.6 will be borne by the LDG 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   11.6,   this   authorization   granted  to  the
Representative  shall be  irrevocable  and shall not be terminated by any act of
any of the holders of LDG Common Stock or by operation of law,  whether by death
or  incompetence  of any holder of LDG Common Stock or by the  occurrence of any
other event except the termination of this Agreement pursuant to Section 1.2(b),
9.1 or 12.12 hereof. If after the execution hereof any such holder of LDG Common
Stock  shall die or  become  incompetent,  the  Representative  is  nevertheless
authorized  and directed to exercise the authority  granted in this Section 11.6
as if such death or  incompetence  had not  occurred  and  regardless  of notice
thereof.  The Representative  shall have no liability to any LDG 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.

requested  by any other party to better  evidence  and reflect the  transactions

         Such  communications  shall be effective  when they are received by the
addressee thereof.  Any party may change its address for such  communications by
giving notice thereof to other parties in conformity  with this Section.  In the
event Lockwood is no longer the Representative,  such successor Representative's
address shall be the address for the LDG Shareholders.

         SECTION 12.4  GOVERNING LAW. The internal laws of the State of Delaware
(irrespective  of its choice of law principles) will govern the validity of this
Agreement, the construction of its terms, and the interpretation and enforcement
of the rights and duties of the parties hereto.  Any dispute  arising  hereunder
shall lie exclusively in the state courts of the State of Delaware.

         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 assigned by
any party without the prior consent of the other,  provided,  however, that HCCH
shall  be  permitted  at any  time  prior to the  Effective  Time to  cause  the
assignment  of Merger  Sub's  rights and  obligations  under this  Agreement  to
another  wholly owned  Subsidiary of HCCH (without in any way relieving  HCCH of
its obligations under this Agreement with respect to Merger Sub or the Merger).

         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 the other agreements and instruments 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  LDG  Shareholders  shall  be  valid  if  consented  to in  writing  by  LDG
Shareholders  holding a majority of the shares of LDG 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 or after approval of
this  Agreement  and the  Merger  by the  shareholders  of HCCH and prior to the
Effective  Time,  this Agreement may be amended or  supplemented  by LDG or HCCH
with  respect  to any of the terms  contained  in this  Agreement,  except  that
following  approval by the  shareholders  of HCCH there


                                       52


shall be no amendment or change to the provisions hereof respect to the Exchange
Ratio  without  further  approval  by the  shareholders  of  HCCH,  and no other
amendment  shall  be  made  which  by law  requires  further  approval  by  such
shareholders without such further approval.

         SECTION 12.9 NO WAIVER.  The failure of any party to enforce any of the
provisions  hereof  shall not be  construed  to be a waiver of the right of such
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 headings
herein are for  reference  purposes  only and shall not in any manner  limit the
construction of this Agreement  which shall be considered as a whole.  The words
"include,"  "includes" and "including"  when used herein shall be deemed in each
case to be followed by the words "without limitation."

         SECTION  12.11  COUNTERPARTS.  This  Agreement  may be  executed in any
number of counterparts,  each of which shall be an original as against any party
whose signature  appears thereon and all of which together shall  constitute one
and the same  instrument.  This Agreement  shall become binding when one or more
counterparts hereof,  individually or taken together,  shall bear the signatures
of all the parties reflected hereon as signatories.

         SECTION  12.12  SUBSEQUENT  AMENDMENTS.  (a) LDG shall  have the right,
promptly upon learning of any fact, circumstance, situation or development prior
to the Effective Date that causes any of the  representations and warranties set
forth in  Article  III to  become  false,  or upon  determining  that any  fact,
circumstance,  situation  or  development  set forth in the  representations  or
warranties in Article III is incorrect,  to deliver to HCCH and Merger Sub prior
to the  Effective  Date  written  amendments  to  the  LDG  Disclosure  Schedule
disclosing the same or any  corrections.  Upon the receipt of any one or more of
such  amendments,  HCCH and Merger Sub may, at their  respective sole option and
discretion and at any time prior to the Effective  Time, (i) without  liability,
withdraw from the  transactions  contemplated  under this Agreement if any fact,
circumstance,  situation  or  development  set  forth  in such  amendment  shall
constitute a Material  Adverse Effect on LDG,  whereupon  this  Agreement  shall
automatically  terminate  without  liability of any party,  or (ii) complete the
Closing,  with  the  aforesaid  LDG  Disclosure  Schedule  that  is so  amended,
whereupon  this  Agreement  shall  automatically  be deemed  to be (x)  properly
amended  thereby and therefore (y) not breached by any such fact,  circumstance,
situation or development or correction disclosed thereby,  regardless of whether
or not any such fact,  circumstance,  situation  or  development  constitutes  a
Material Adverse Effect on LDG.

         (b) HCCH shall  have the right,  promptly  upon  learning  of any fact,
circumstance,  situation or development  prior to the Effective Date that causes
any of the  representations  and  warranties  set forth in  Article IV to become
false, or upon determining that any fact, circumstance, situation or development
set forth in the  representations  or warranties in Article IV is incorrect,  to
deliver  to LDG  prior to the  Effective  Date  written  amendments  to the HCCH
Disclosure Schedule disclosing the same or any corrections.  Upon the receipt of
any one or more


                                       53


of such  amendments,  LDG and the Affiliated  Companies and the LDG Shareholders
may, at their respective sole option and discretion and at any time prior to the
Effective  Time,  (i)  without   liability,   withdraw  from  the   transactions
contemplated  under  this  Agreement  if any fact,  circumstance,  situation  or
development  set forth in such  amendment  shall  constitute a Material  Adverse
Effect on HCCH,  whereupon this Agreement shall automatically  terminate without
liability of any party,  or (ii) complete the Closing,  with the aforesaid  HCCH
Disclosure  Schedule  that  is  so  amended,   whereupon  this  Agreement  shall
automatically be deemed to be (x) properly amended thereby and therefore (y) not
breached by any such fact, circumstance,  situation or development or correction
disclosed  thereby,  regardless  of whether or not any such fact,  circumstance,
situation or development constitutes a Material Adverse Effect on HCCH.

         IN WITNESS WHEREOF,  the parties hereto have executed this Agreement as
of the date first above written.

24th day of May, 1996 by and between HCCH INSURANCE  HOLDINGS,  INC., a Delaware
corporation  ("HCCH"),  and the undersigned  shareholder  ("Shareholder") of LDG
MANAGEMENT COMPANY INCORPORATED ("LDG").

         This  Agreement  is  entered  into  in  connection  with  that  certain
Agreement  and  Plan of  Reorganization  dated  as of  February  22,  1996  (the
"Reorganization Agreement") among HCCH, LDG, Stephen J. Lockwood ("SJL"), Walter
L. Suydam  ("WLS") and others.  The  Reorganization  Agreement  provides for the
merger (the "Merger") of a newly formed  subsidiary of HCCH with and into LDG in
a  transaction  in which  issued and  outstanding  shares of common stock of LDG
$1.00 par value (the "LDG Stock") will be converted into shares of common stock,
$1.00  par  value  per  share,  of HCCH  (the  "HCCH  Stock")  on the  terms and
conditions set forth in the  Reorganization  Agreement.  Capitalized  terms used
herein and not defined herein shall have their defined  meanings as set forth in
the Reorganization Agreement.

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


              1.  TAX AND  ACCOUNTING  TREATMENT.  Shareholder  understands  and
agrees that it is intended that the Merger will be treated as a "reorganization"
for federal  income tax purposes and as a "pooling of  interests"  in accordance
with generally accepted  accounting  principles and the applicable General Rules
and Regulations published by the Securities and Exchange Commission (the "SEC").
Shareholder  further  understands  and  agrees  that,  as of  the  date  hereof,
Shareholder may be deemed to be an "Affiliate" of LDG (i) for application of the
pooling of interests requirements and (ii) within the meaning of Rule 145 ("Rule
145")  promulgated under the Securities Act of 1933, as amended (the "Securities
Act"),  although nothing contained herein should be construed as an admission of
either such fact.

               2. RELIANCE  UPON  REPRESENTATIONS,   WARRANTIES  AND  COVENANTS.
Shareholder  has been informed that the treatment of the Merger as a "pooling of
interests" for financial  accounting  purposes is dependent,  in part,  upon the
accuracy of  Shareholder's  representations  and warranties set forth herein and
Shareholder's compliance with Shareholder's covenants set forth herein, and that
a  reorganization  for federal  income tax purposes  requires  that a sufficient
number of former  shareholders  of LDG maintain a meaningful  continuing  equity
ownership  interest in HCCH after the Merger.  Shareholder  understands that the
representations,  warranties  and covenants set forth herein will be relied upon
by HCCH, LDG, SJL, WLS, their respective  counsel and accounting firms and other
shareholders of LDG.

               3.  REPRESENTATIONS,  WARRANTIES  AND  COVENANTS OF  SHAREHOLDER.
Shareholder represents, warrants and covenants as follows:





                   (a)  Shareholder has full power and authority to execute this
         Agreement, to make the representations, warranties and covenants herein
         contained and to perform Shareholder's obligations hereunder.

                   (b)  Appendix A attached  hereto sets forth all shares of LDG
         Stock  owned  by  Shareholder,  including  all LDG  Stock  as to  which
         Shareholder  has sole or  shared  voting  or  investment  power and all
         rights and options to acquire LDG Stock.

                   (c) Except as set forth on Schedule A,  Shareholder  will not
         sell, transfer,  exchange, pledge, or otherwise dispose of, or make any
         offer or agreement  relating to any of the  foregoing  with respect to,
         any shares of HCCH Stock that  Shareholder  may  acquire in  connection
         with the  Merger or  acquire  upon  exercise  of any option or right to
         acquire  HCCH Stock,  which  option or right is acquired in  connection
         with the Merger,  or any  securities  that may be paid as a dividend or
         otherwise  distributed  thereon  or with  respect  thereto or issued or
         delivered  in exchange or  substitution  therefor  (all such shares and
         other securities of HCCH being herein sometimes  collectively  referred
         to as "Restricted Securities"),  or any option, right or other interest
         with respect to any Restricted Securities,  unless (i) such transaction
         is  permitted  pursuant  to  Rule  145  under  the  Securities  Act (as
         described in Section 5 below),  (ii) counsel  representing  Shareholder
         shall have advised HCCH in a written  opinion  letter  satisfactory  to
         HCCH and  HCCH's  legal  counsel,  and upon  which  HCCH and its  legal
         counsel may rely, that no  registration  under the Securities Act would
         be required in  connection  with the proposed  sale,  transfer or other
         disposition,  (iii) a registration  statement  under the Securities Act
         covering the HCCH Stock  proposed to be sold,  transferred or otherwise
         disposed  of,  describing  the manner and terms of the  proposed  sale,
         transfer or other  disposition,  and  containing a current  prospectus,
         shall  have  been  filed  with the SEC and  made  effective  under  the
         Securities Act, or (iv) an authorized  representative  of the SEC shall
         have rendered  written advice to Shareholder  (sought by Shareholder or
         counsel  to  Shareholder,  with a copy  thereof  and all other  related
         communications delivered to HCCH) to the effect that the SEC would take
         no action,  or that the staff of the SEC would not  recommend  that the
         SEC  take  action,   with  respect  to  the  proposed   disposition  if
         consummated.

                   (d)  Notwithstanding any other provision of this Agreement to
         the contrary,  except as set forth on Schedule A,  Shareholder will not
         sell,  transfer,  exchange,  pledge or otherwise  dispose of, or in any
         other way reduce  Shareholder's  risk of ownership or investment in, or
         make any  offer or  agreement  relating  to any of the  foregoing  with
         respect to any LDG Stock or any rights, options or warrants to purchase
         LDG Stock, or any Restricted Securities or other securities of HCCH (i)
         during the 30-day period  immediately  preceding the Effective  Time of
         the Merger and (ii)  until  such time after the  Effective  Time of the
         Merger as HCCH has publicly  released a report  including  the combined
         financial  results  of HCCH and LDG for a period of at least 30 days of
         combined  operations  of HCCH and LDG within the meaning of  Accounting
         Series Release No. 130, as amended,  of the SEC. HCCH agrees to publish
         such financial  results  expeditiously in a manner  consistent with its
         prior practices;  provided that nothing


                                       2

         contained  herein  shall obligate HCCH to publish its financial results
         other than on a quarterly basis.



                   (e) Except as set forth in Schedule A, Shareholder has and as
         of the  Effective  Time of the  Merger  will have,  no present  plan or
         intention (a "Plan") to sell, transfer, exchange, pledge (other than in
         a  preexisting  bona fide  margin  account)  or  otherwise  dispose of,
         including  a  distribution  by a  partnership  to  its  partners,  or a
         corporation to its stockholders, or any other transaction which results
         in a  reduction  in the  risk of  ownership  (any of the  foregoing,  a
         "Sale")  of more than fifty  percent  (50%) of the shares of HCCH Stock
         that  Shareholder  may acquire in  connection  with the Merger,  or any
         securities  that may be paid as a  dividend  or  otherwise  distributed
         thereon or with  respect  thereto or issued or delivered in exchange or
         substitution therefor.  For purposes of the preceding sentence,  shares
         of LDG Stock (or the portion  thereof) with respect to which a Sale (A)
         in a Related  Transaction (as defined below) or (B) will occur prior to
         the  Merger,  shall be  considered  to be shares of LDG Stock  that are
         exchanged for HCCH Stock in the Merger and then disposed of pursuant to
         a Plan.  Shareholder is not aware of, or participating  in, any Plan on
         the part of LDG  shareholders  to engage in Sales of the shares of HCCH
         Stock to be issued in the Merger  such that the  aggregate  fair market
         value, as of the Effective Time of the Merger, of the shares subject to
         such Sales would  exceed  fifty  percent  (50%) of the  aggregate  fair
         market value of all shares of outstanding LDG Stock  immediately  prior
         to the Merger.  For purposes of the preceding  sentence,  shares of LDG
         Stock  with  respect  to which a  pre-Merger  Sale  occurs in a Related
         Transaction,  shall be  considered  to be shares of LDG Stock  that are
         exchanged for HCCH Stock in the Merger and then disposed of pursuant to
         a Plan.  A Sale of HCCH  Stock  shall be  considered  to have  occurred
         pursuant  to a Plan if,  among  other  things,  such  Sale  occurs in a
         Related  Transaction.  For  purposes of this  Section 3 (e), a "Related
         Transaction"  shall mean a transaction that is in contemplation  of, or
         related or pursuant to, the Merger or the Reorganization  Agreement. If
         any of Shareholder's representations in this Section 3 (e) ceases to be
         true at any time prior to the Effective Time of the Merger, Shareholder
         shall deliver to each of LDG and HCCH,  prior to the Effective  Time of
         the Merger, a written statement to that effect, signed by Shareholder.


               4. RULE 144 AND 145.  From and  after the  Effective  Time of the
Merger and for so long as is  necessary in order to permit  Shareholder  to sell
the HCCH Stock held by and  pursuant  to Rule 145,  if  applicable,  and, to the
extent applicable, Rule 144 under the Securities Act ("Rule 144"), HCCH will use
its reasonable best efforts to file on a timely basis all reports required to be
filed by it pursuant to Section 13 or Section 15(d) of the  Securities  Exchange
Act of 1934, as amended,  referred to in paragraph  (c)(1) of Rule 144, in order
to permit  Shareholder  to sell the HCCH Stock held by it  pursuant to the terms
and  conditions  of  Rule  145  and  the  applicable  provisions  of  Rule  144.
Shareholder  understands that, except as may be set forth in the  Reorganization
Agreement,  HCCH is under no obligation to register the sale,  transfer or other



                                       3


disposition  of any  Restricted  Securities by or on behalf of Shareholder or to
take any other action  necessary in order to make  compliance  with an exemption
from registration available.



              5.  LIMITED RESALES.  Shareholder  understands that, under current
law, in addition to the restrictions  imposed under Section 3 of this Agreement,
the provisions of Rule 145 may limit Shareholder's  public resales of Restricted
Securities, in the manner set forth in subsections (a), (b) and (c) below, until
such time as Shareholder may have beneficially owned, within the meaning of Rule
144(d),  the  Restricted  Securities  for  certain  periods  which,  in  certain
circumstances,  which may or may not be applicable to Shareholder,  may be for a
period of at least two years (or in some cases three years) (or shorter  periods
when and if permitted under applicable law as in effect in the future) after the
date of the Merger,  and thereafter if and for so long as Shareholder  remains a
HCCH affiliate:

                   (a) Unless and until the restriction  "cut-off" provisions of
         Rule 145 (d) (2) or Rule 145 (d) (3) set forth below become  available,
         public  resales of Restricted  Securities may currently only be made by
         Shareholder in compliance with the requirements of Rule 145(d)(1). Rule
         145(d)(1)  currently permits such resales only (i) while HCCH meets the
         public  information  requirements  of Rule  144(c),  (ii)  in  brokers'
         transactions or in transactions  directly with a market maker and (iii)
         where the aggregate  number of Restricted  Securities  sold at any time
         together  with all sales of HCCH Stock sold for  Shareholder's  account
         during the preceding  three month period does not exceed the greater of
         (x) 1% of the HCCH  Common  Stock then  outstanding  or (y) the average
         weekly  volume of  trading  in HCCH  Stock on all  national  securities
         exchanges and/or reported  through the automated  quotation system of a
         registered  securities  association  during  the  four  calendar  weeks
         preceding the date of receipt of the order to execute the sale.

                   (b)  Shareholder may currently make  unrestricted  resales of
         Restricted  Securities  pursuant to Rule 145 (d) (2) if (i) Shareholder
         has  beneficially  owned  (within  the  meaning  of Rule  144  (d)) the
         Restricted  Securities for at least two years (or shorter  periods when
         and if permitted under applicable law as in effect in the future) after
         the Effective Time of the Merger,  (ii) Shareholder is not an affiliate
         as  defined  in Rule  144(a) of HCCH and (iii)  HCCH  meets the  public
         information requirements of Rule 144(c).

                   (c) Shareholder may make  unrestricted  resales of Restricted
         Securities pursuant to Rule 145 (d) (3) if Shareholder has beneficially
         owned  (within the meaning of Rule 144 (d)) the  Restricted  Securities
         for at least  three  years (or shorter  periods  when and if  permitted
         under  applicable  law as in effect in the future) and is not,  and has
         not been for at least three months, an affiliate of HCCH.

                   (d) HCCH acknowledges that the provisions of Section 3 (c) of
         this Agreement  will be satisfied as to any sale by the  Shareholder of
         the Restricted  Securities pursuant to Rule 145 (d) by delivery to HCCH
         of a broker's letter and a letter from the Shareholder  with respect to
         that sale stating that each of the above-described requirements of Rule
         145 (d) (1) has been met or is  inapplicable  by virtue of Rule 145 (d)
         (2) or


                                       4


         Rule  145(d)(3);  provided,  that  HCCH  has  no  reasonable  basis  to
         believe such sales were not made in compliance  with such provisions of
         Rule 145(d).



              6.  NOTICES.   All   notices,    requests,    demands   or   other
