                                                                    ----

     NOW, THEREFORE, in consideration of the premises and of the
representations, warranties, covenants and agreements herein contained and other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

1.   THE MERGER

     1.1   THE MERGER.  At the Effective Time (as defined in Section 4.2), the
Company shall be merged with and into Newco pursuant to this Agreement and
Articles of Merger (the "Articles of Merger") substantially in the form attached
                         ------------------
as SCHEDULE 1.1 hereto, and the separate corporate existence of the Company
shall cease.  Newco, as it exists from and after the Effective Time, is
sometimes referred to as the "Surviving Corporation."  The Surviving
                              ---------------------
Corporation's name will be changed to that of the Company immediately after the
Effective Time.

     1.2  ARTICLES OF INCORPORATION; BYLAWS, DIRECTORS AND OFFICERS.  At the
Effective Time:

          (a)  The Articles of Incorporation of Newco, as in effect immediately
prior to the Effective Time, which are attached as EXHIBIT 1.2(A), shall be the
Articles of Incorporation of the Surviving Corporation unless and until
thereafter amended as provided therein and under the laws of the State of Texas
(the "State Corporate Laws"), provided, that the provisions relating to the
      --------------------
indemnification of officers and directors contained therein as amended at the
Effective Time shall not be amended until the sixth (6th) anniversary of the
Closing Date (as defined in Section 4.1).

          (b)  The Bylaws of Newco, as in effect immediately prior to the
Effective Time, which are attached as EXHIBIT 1.2(B), shall be the Bylaws of the
Surviving Corporation unless and until thereafter amended as provided therein
and under the State Corporate Laws; provided, that the provisions

                                       1
<PAGE>

relating to the indemnification of officers and directors contained therein
shall not be amended until the sixth (6th) anniversary of the Closing Date.

          (c)  The directors of the Surviving Corporation shall be as set forth
on SCHEDULE 1.2(C) until their successors are elected and qualified, and the
initial officers of the Surviving Cor poration shall be as set forth on SCHEDULE
1.2(C) until their successors are elected and qualified.

     1.3  EFFECTS OF THE MERGER.  The Merger shall have the effects provided
therefor by the State Corporate Laws.  Without limiting the generality of the
foregoing, and subject thereto, at the Effective Time (i) all the rights,
privileges, immunities, powers and franchises, of a public as well as of a
private nature, and all property, real, personal and mixed, and all debts due on
whatever account, including without limitation subscriptions to shares, and all
other choses in action, and all and every other interest of or belonging to or
due to the Company or Newco shall be taken and deemed to be transferred to, and
vested in, the Surviving Corporation without further act or deed; and all
property, rights and privileges, immunities, powers and franchises and all and
every other interest shall be thereafter as effectually the property of the
Surviving Corporation, as they were of the Company and Newco, and (ii) all
debts, liabilities, duties and obligations of the Company and Newco shall become
the debts, liabilities, duties and obligations of the Surviving Corporation and
the Surviving Corporation shall thenceforth be responsible and liable for all
the debts, liabilities, duties and obligations of the Company and Newco and
neither the rights of creditors nor any liens upon the property of the Company
or Newco shall be impaired by the Merger, and may be enforced against the
Surviving Corporation.

2.   CONVERSION AND EXCHANGE OF STOCK

     2.1  MANNER OF CONVERSION.  At the Effective Time, by virtue of the Merger
and without any action on the part of CCC, Newco, the Company or the
Shareholders, the shares of capital stock of each of the Constituent
Corporations shall be converted as follows:

          (a)  Capital Stock of Newco.  Each issued and outstanding share of
               ----------------------
capital stock of Newco shall continue to be issued and outstanding and shall
represent shares of stock of the Surviving Corporation. Each stock certificate
of Newco evidencing ownership of any such shares shall continue to evidence
ownership of such shares of capital stock of the Surviving Corporation.

          (b)  Cancellation of Certain Shares of Capital Stock of the Company.
               --------------------------------------------------------------
All shares of capital stock of the Company that are owned directly or indirectly
by the Company shall be canceled and no stock of CCC or other consideration
shall be delivered in exchange therefor.

          (c)  Conversion of Capital Stock of the Company.  Subject to Section
               ------------------------------------------
2.1(d), and Sections 2.2, 2.3, 2.4, and 3.1, each issued and outstanding share
of Company Common Stock (other than shares to be canceled pursuant to Section
2.1(b)), that is issued and outstanding immediately prior to the Effective Time
shall automatically be canceled and extinguished and converted, without any
action on the part of the holder thereof, into the right to receive at the time
and in the amounts described in this Agreement (i) an amount of cash equal to
the cash portion of the Base Merger Consideration (as described in Section
2.2(a)) divided by the number of shares of Company Common Stock issued and
outstanding immediately prior to the Effective Time (other than shares to be
canceled pursuant to Section 2.1(b)), (ii) that number of shares of CCC common
stock, $.001 par value ("CCC Common Stock"), valued at the Merger Price (as
                         ----------------
described in Section 2.2(a)), that is equal in value to the CCC Common Stock
portion of the Base Merger Consideration (as defined in Section 2.2(a)) divided
by the number of shares of Company Common Stock issued and outstanding
immediately prior to the Effective Time

                                       2
<PAGE>

(other than shares to be canceled pursuant to Section 2.1(b)), (iii) an amount
of cash equal to 50% of  the Contingent Merger Consideration (as defined in
Section 2.3(a)) divided by the number of shares of Company Common Stock issued
and outstanding immediately prior to the Effective Time (other than shares to be
canceled pursuant to Section 2.1(b)), and (iv) that number of shares of CCC
Common Stock, valued at the Earn Out Period Average Price (as defined in Section
2.3(d)), that is equal in value to 50% of the Contingent Merger Consideration
divided by the number of shares of Company Common Stock outstanding immediately
prior to the Effective Time (other than shares to be canceled pursuant to
Section 2.1(b)).  All such shares of Company Common Stock, when so converted,
shall no longer be outstanding and shall automatically be canceled and retired
and shall cease to exist, and each holder of a certificate representing any such
shares shall cease to have any rights with respect thereto, except the right to
receive the consideration therefor upon the surrender of such certificate in
accordance with Sections 2.2, 2.3 and 2.4 of this Agreement.

          (d)  Fractional Shares.  No fractional shares of CCC Common Stock
               -----------------
shall be issued pursuant to this Agreement, but in lieu thereof each holder of
shares of Company Common Stock who would otherwise be entitled to receive a
fraction of a share of CCC Common Stock shall receive from CCC an amount of cash
equal to the Merger Price or the Earn Out Period Average Price, as applicable,
multiplied by the fraction of a share of CCC Common Stock to which such holder
would otherwise be entitled. The fractional share interests of each Shareholder
shall be aggregated, so that no Shareholder shall receive cash in an amount
greater than the value of one full share of CCC Common Stock.

     2.2  BASE MERGER CONSIDERATION.

          (a)  For purposes of this Agreement, the "Base Merger Consideration"
                                                    -------------------------
shall be $70,000,000. Of the Base Merger Consideration, $35,000,000 shall be
paid in cash at Closing (as defined in Section 4.1) in immediately available
funds. The remaining $35,000,000 of the Base Merger Consideration shall be paid
at Closing in shares of CCC Common Stock valued at a price per share of $23.00
(the "Merger Price") which the parties hereto irrevocably agree is equal to
      ------------
the sum of (i) the closing price of CCC Common Stock on February 19, 1998, plus
(ii) the closing price of CCC Common Stock on March 5, 1998, plus (iii) the
"Interim Period Average" (as such term is defined below), divided by 3.
 ----------------------
Interim Period Average means the sum of the closing prices of CCC Common Stock
on every trading day from and including the date referenced in clause (i) above
and through and including the date referenced in clause (ii) above, divided by
the number of trading days included in such period. The closing price of CCC
Common Stock on a trading day, for purposes of this calculation, shall be the
day's last trade price as reported on the Nasdaq National Market (or if no trade
price is reported for any such day, the average of the last bid and ask prices

     2.3  CONTINGENT MERGER CONSIDERATION.

          (a)  For purposes of this Agreement, but subject to the provisions of
subsections (i), (ii), and (iii) below, the "Contingent Merger Consideration"
                                             -------------------------------
shall mean the sum of the First Year Earn Out Amount and the Second Year Earn
Out Amount, provided however that in no event shall the Contingent Merger
Consideration exceed $30,000,000 (the "Maximum Earn Out Amount").
                                       -----------------------

          (i)   The "First Year Earn Out Amount" shall mean the lesser of
                     --------------------------
(A) the Actual Earn Out EBIT (hereinafter defined) of the Surviving Corporation
for the twelve month period ending on the last day of the month of the first
anniversary of the Closing, or (B) $15,000,000.

         (ii)   The "Second Year Earn Out Amount" shall mean the lesser of (A)
               ---------------------------
the Actual Earn Out EBIT of the Surviving Corporation for the twelve month
period ending on the last day of the month of the second anniversary of the
Closing, or (B) the sum of $15,000,000 plus the amount by which $15,000,000
exceeds the greater of $14,000,000 or the First Year Earn Out Amount.

        (iii)   For purposes of this Section 2.3, "Actual Earn Out EBIT" for any
                                             --------------------
period is equal to the following for such period: the net income of the
Surviving Corporation (A) plus interest expense, income taxes, extraordinary
items, cumulative effect of accounting changes and discontinued operations and
(B) less interest income calculated in accordance with generally accepted
accounting principles ("GAAP") consistently applied; provided however, that in
                        ----
any event Actual Earn Out EBIT shall (1) exclude any increases in intangible
assets of the Surviving Corporation, (2) exclude the amortization of goodwill
and other intangibles recognized by CCC in connection with the acquisition of
the Company or any future acquisitions, (3) exclude expenses (including
corporate overhead) of CCC other than those expenses incurred for the benefit of
the Surviving Corporation that do not duplicate expenses incurred by the
Surviving Corporation nor exceed the amounts of similar expenses incurred in the
most recently ended fiscal year by the Company prior to the Closing, and (4)
include depreciation and amortization of assets of the Surviving Corporation
except to the extent such amounts result from an increase in the book value of
the assets resulting from the Merger.  CCC's Accountant (hereinafter defined)
will calculate the Contingent Merger Consideration and the Actual Earn Out EBIT
applying the same accounting principles applied by the Company, with all such
computations made (and definitions used) in the same way the computations were
made (and definitions were used) by the Company prior to the Closing and will
conform to the methods of accounting utilized consistently during the calendar
years 1996 and 1997 for the Company, provided in each case that such
computations were in accordance with GAAP.

          (b)  Price Waterhouse LLP, CCC's independent accountant ("CCC's
                                                                   ------
Accountant"), will determine the Actual Earn Out EBIT for each of the years
ending March 31, 1999 and 2000 and deliver prompt notice of such amount to the
Shareholders (the "Earn Out EBIT Notice") with supporting documentation.  The
                   --------------------
Shareholders (through the Representative as defined in Section 13.14(a)) shall
have the right to inspect, audit and make extracts from all of the records,
files and books of account of CCC relating to the Actual Earn Out EBIT for
purposes of verifying the amount of the consideration payable pursuant to
Section 2.3, at reasonable times during business hours, upon advance notice to
CCC.

          (c)  The Shareholders (through the Representative) shall have thirty
(30) days from the receipt of the Earn Out EBIT Notice to notify CCC if they
dispute the amount of the Actual Earn Out EBIT. If CCC has not received notice
of any such dispute within such 30-day period, the Actual Earn Out EBIT
contained in the Earn Out EBIT Notice shall be final. If, however, the
Shareholders (through the Representative) have delivered notice of such a
dispute to CCC within such 30-day period, then CCC

                                       4
<PAGE>

shall, pursuant to Section 2.3(d) below, pay such amount of the Contingent
Merger Consideration that is not subject to any dispute and CCC's Accountant
shall select an independent accounting firm that has not represented any of the
parties hereto within the preceding two (2) years and is one of the six largest
accounting firms in the United States (each, a "New Accounting Firm") to review
                                                -------------------
the amount of the disputed Actual Earn Out EBIT, the books of the Surviving
Corporation, and the Earn Out EBIT Notice (and related information) to determine
the amount, if any, that the Actual Earn Out EBIT is in error.  Such New
Accounting Firm shall be confirmed by the Shareholders through the
Representative and CCC within five (5) days of its selection, unless there is an
actual conflict of interest.  The New Accounting Firm shall make its
determination of the Actual Earn Out EBIT (the "Revised Earn Out EBIT") if any,
                                                ---------------------
within thirty (30) days of its selection.  The Revised Earn Out EBIT shall be
final and binding on the parties hereto, and, upon such determination, CCC shall
be entitled or required to adjust the First Year Earn Out Amount or the Second
Year Earn Out Amount accordingly.  If the Revised Earn Out EBIT is higher than
the Actual Earn Out EBIT, CCC shall pay to the Shareholders interest, at the
Prime Rate (defined below), on the deficiency from the date that is three months
after the end of the period with respect to which the disputed Actual Earn Out
EBIT is calculated.  The costs of the New Accounting Firm shall be borne by CCC
if the Revised Earn Out EBIT is higher than the Actual Earn Out EBIT and by the
Shareholders in all other cases.  For purposes of this Section, the term "Prime
                                                                          -----
Rate" shall mean the annual rate of interest announced by Citibank, N.A. in New
----
York, New York as its prime rate in effect on the Contingent Merger
Consideration Payment Date.

          (d)  The Contingent Merger Consideration described in Section 2.3 (a),
will be paid 50% in cash and 50% in shares of CCC Common Stock and will be paid
in a single lump payment by federal wire transfer of same day funds promptly
following the determination of the Actual Earn Out EBIT for the applicable
period by CCC's Accountant, which shall be made not later than the date that is
three months after the end of the period with respect to which the Actual Earn
Out EBIT is calculated unless the Shareholders dispute the Actual Earn Out EBIT
in accordance herewith. For purposes of determining the number of shares of CCC
Common Stock that are issuable as part of the Contingent Merger Consideration,
the value of each such share shall be equal to the Earn Out Period Average
Prices for the thirty (30) trading days prior to and including the last day of
March 1999, in the case of the First Year Earn Out Amount, and March 2000, in
the case of the Second Year Earn Out Amount. The "Earn Out Period Average
                                                  -----------------------
Price"
-----
means the quotient of (i) the sum of the closing price of a share of CCC
Common Stock on the Nasdaq National Market on each trading day from and
including the date that is thirty (30) trading days prior to and including the
last day of March 1999, in the case of CCC Common Stock deliverable with respect
to the First Year Earn Out Amount, and March 2000 in the case of CCC Common
Stock deliverable with respect to the Second Year Earn Out Amount, (or if no
trade price is reported for any such day, the average of the last bid and ask
prices for the CCC Common Stock), divided by (ii) 30. The date or dates on which
the Contingent Merger Consideration is paid to the Shareholders is hereinafter
referred to as the "Contingent Merger Consideration Payment Date." The
certificates evidencing CCC Common Stock received as part of the Merger
Consideration shall be issued in the denominations and names of the Shareholders
as set forth in written instructions delivered by the Shareholders to CCC at
least five (5) business days prior to the Closing Date and the Contingent Merger
Consideration Payment Date or Dates, as applicable. The shares of CCC Common
Stock to be issued in respect of the Contingent Merger Consideration shall be
registered under the 1933 Act and approved for quotation on the Nasdaq National
Market.

          (e)  If, on or prior to a Contingent Merger Consideration Payment
Date but after calculation of the Earn Out Period Average Price with respect
thereto, CCC should split or combine the CCC Common Stock, or pay a stock
dividend or other stock distribution in CCC Common Stock, or otherwise change
the CCC Common Stock into any other securities, or make any other dividend or

                                       5
<PAGE>

distribution on the CCC Common Stock (other than normal quarterly dividends, as
the same may be adjusted from time to time and in the ordinary course), then the
number of shares of CCC Common stock issuable as the Contingent Merger
Consideration will be appropriately adjusted to reflect such split, combination,
dividend or other distribution or change.

          (f) In the event CCC or any of its subsidiaries takes any action or
omits to take any action which is not commercially reasonable in the
circumstances for the conduct of the business of CCC and its subsidiaries taken
as a whole and which has a direct, quantifiable, negative impact on the
Contingent Merger Consideration; then, in any such event, the parties, in good
faith, shall make reasonable adjustments in the calculation of the Actual Earn
Out EBIT as may be necessary to neutralize the impact of any such action or
omission.

          (g) CCC and Newco agree that separate books and records will be kept
for the Surviving Corporation during the period from the Closing through March
31, 2000.

     2.4  EXCHANGE OF CERTIFICATES AND PAYMENT OF CASH.

          (a)  Delivery of Consideration.  At Closing, in exchange for the
               -------------------------

an amount sufficient for payment in lieu of fractional shares pursuant to
Section 2.1(d)), with all cash payments to be made by federal wire transfer of
immediately available funds pursuant to wire transfer instructions provided by
the Shareholders at least two business days prior to Closing.  The certificates

          ---------------------------------
Shareholders shall deliver to CCC the certificates (the "Certificates")
                                                         ------------
representing Company Common Stock owned by them, accompanied by blank stock
powers duly executed by each respective Shareholder and with all necessary
transfer tax and other revenue stamps, acquired at the Shareholder's expense,
affixed and canceled.  Each Shareholder shall promptly cure any deficiencies
with respect to the stock powers accompanying such Certificates.  The
Certificates so delivered shall forthwith be canceled.  Until delivered as
contemplated by this Section 2.4(b), each Certificate shall be deemed at any
time after the Effective Time to represent the right to receive upon such
surrender the number of shares of CCC Common Stock and the amount of cash as
provided by this Article 2 and the applicable provisions of the State Corporate
Laws.

          (c)  No Further Ownership Rights in Capital Stock of the Company.
               -----------------------------------------------------------
All CCC Common Stock and cash to be delivered (including CCC Common Stock

exchange of shares of Company Common Stock in accordance with the terms hereof
shall be deemed to have been delivered in full satisfaction of all rights
pertaining to such shares of Company Common Stock, and, following the Effective
Time, the Shareholders shall have no further rights to, or ownership in, shares
of capital stock of the Company. There shall be no further registration of
transfers on the stock transfer books of the Surviving Corporation of the shares
of Company Common Stock which were issued and outstanding immediately prior to
the Effective Time.

this Section 2.4.

          (d)  Lost, Stolen or Destroyed Certificates.  If any certificates
          --------------------------------------

destroyed, then CCC shall cause payment to be made in exchange for such lost,
stolen or destroyed certificates, upon the delivery to CCC of an affidavit of
that fact by the holder thereof, of such shares of CCC Common Stock and cash as
provided in Section 2.1; provided, however that CCC may, in its discretion and
as a condition precedent to the issuance thereof, require the owner of such
lost, stolen or destroyed certificates to deliver a bond in such sum as it may
reasonably direct as indemnity against any claim that may be made against CCC
with respect to the certificates alleged to have been lost, stolen or destroyed.

          (e)  No Liability.  Notwithstanding anything to the contrary in this
          ------------
Section 2.4, none of the Surviving Corporation or any party hereto shall be
liable to a holder of shares of Company Common Stock for any amount paid to a

certificates and instruments representing or evidencing such securities, and all
cash and non-cash dividends and other property at any time received, receivable

property to CCC to be held hereunder as Pledged Assets; and

             (iii)   all cash and non-cash proceeds of all of the foregoing

with the assets of CCC or any of its subsidiaries.

          (c)  The Pledged Assets shall be available to satisfy any
indemnification obligations of each Shareholder pursuant to (and subject to the

7.   COVENANTS

     7.1  TAX MATTERS.

          (a)  The following provisions shall govern the allocation of
responsibility as between the Shareholders, on the one hand, and the Surviving
Corporation, on the other, for certain tax matters following the Closing Date:

                                       28
<PAGE>

               (i)   The Representative shall cause to be prepared and cause to
be filed, within the time and in the manner provided by law, all Tax Returns of
the Company for all periods ending on or before the Closing Date that are due
after the Closing Date. The Shareholders shall pay to the Surviving Corporation
on or before the due date of such Tax Returns the amount of all Taxes shown as
due on such Tax Returns to the extent that such Taxes are not reflected in the
current liability accruals for Taxes (excluding reserves for deferred Taxes)
shown on the Company's books and records as of the Closing Date. Such Returns
shall be prepared and filed in accordance with applicable law and in a manner
consistent with past practices and shall be subject to review and approval by
CCC. To the extent reasonably requested by the Shareholders or required by law,
CCC and the Surviving Corporation shall participate in the filing of any Tax
Returns filed pursuant to this paragraph.

              (ii) The Surviving Corporation shall prepare or cause to be
prepared and file or cause to be filed any Tax Returns for Tax periods which
begin before the Closing Date and end after the Closing Date. The Shareholders
shall pay to the Surviving Corporation within fifteen (15) days after the date
on which Taxes are paid with respect to such periods an amount equal to the
portion of such Taxes which relates to the portion of such taxable period ending
on the Closing Date to the extent such Taxes are not reflected in the current
liability accruals for Taxes (excluding reserves for deferred Taxes) shown on
the Company's books and records as of the Closing Date. Notwithstanding the
preceding sentence, the Shareholders shall not be responsible for any tax that
may arise under Section 4978 of the Code as a result of the consummation of the
Merger. For purposes of this Section 7.1, in the case of any Taxes that are
imposed on a periodic basis and are payable for a taxable period that includes
(but does not end on) the Closing Date, the portion of such Tax which relates to
the portion of such taxable period ending on the Closing Date shall (A) in the
case of any Taxes other than Taxes based upon or related to income or receipts,
be deemed to be the amount of such Tax for the entire taxable period multiplied
by a fraction the numerator of which is the number of days in the taxable period
ending on the Closing Date and the denominator of which is the number of days in
the entire taxable period, and (B) in the case of any Tax based upon or related
to income or receipts be deemed equal to the amount which would be payable if
the relevant taxable period ended on the Closing Date. Any credits relating to a
taxable period that begins before and ends after the Closing Date shall be taken
into account as though the relevant taxable period ended on the Closing Date.
All determinations necessary to give effect to the foregoing allocations shall
be made in a manner consistent with prior practice of the Company. The Surviving
Corporation will pay over to the Shareholders any Tax refunds attributable to
Tax periods ending on or before the Closing Date; provided that either (i) the
Company paid the Taxes subject to the refund, (ii) such Taxes were reflected in
the current liability accruals for Taxes (excluding reserves for deferred Taxes)
shown on the Company's books and records as of the Closing Date, or (iii) that
the Shareholders paid to the Company or to the applicable taxing authority,
pursuant to this Section 7.1(a), the Taxes subject to the refund(s).

               (iii) CCC and the Surviving Corporation on the one hand and
the Shareholders on the other hand shall (A) cooperate fully, as reasonably
requested, in connection with the preparation and filing of Tax  Returns
pursuant to this Section 7.1 and any audit, litigation or other proceeding with
respect to Taxes; (B) make available to the other, as reasonably requested, all
information, records or documents with respect to Tax matters pertinent to the
Company for all periods ending prior to or including the Closing Date; and (C)
preserve information, records or documents relating to Tax matters pertinent to
the Company that is in their possession or under their control until the
expiration of any applicable statute of limitations or extensions thereof.

               (iv)  The Shareholders shall timely pay all transfer,
documentary, sales, use, stamp, registration and other Taxes and fees arising
from or relating to the transactions contemplated by

                                       29
<PAGE>

this Agreement, and the Shareholders shall, at their own expense, file all
necessary Tax Returns and other documentation with respect to all such transfer,
documentary, sales, use, stamp, registration, and other Taxes and fees. If
required by applicable law, CCC and the Surviving Corporation will join in the
execution of any such Tax Returns and other documentation.

     7.2  ACCOUNTS RECEIVABLE.  In the event that all Accounts Receivable
(other than those specified on SCHEDULE 5.12 are not collected in full (net of
reserves specified in Section 5.12 and retainage) within 180 days after the
Closing (or with respect to those Accounts Receivable specified on SCHEDULE
5.12, within the number of days after the Closing specified on such SCHEDULE)
then, at the request of the Surviving Corporation, the Shareholders shall pay
(based on their percentage ownership of the Company immediately prior to the
Effective Time) the Surviving Corporation an amount equal to the Accounts
Receivable not so collected, and upon receipt of such payment the Surviving
Corporation shall assign to the Shareholders making the payment all of their
rights with respect to the uncollected Accounts Receivable giving rise to the
payment and shall also thereafter promptly remit any excess collections received
by it with respect to such assigned Accounts Receivable.  The Surviving
Corporation shall provide reasonable assistance to the Shareholders with
collections of the uncollected Accounts Receivable.

     7.3  [INTENTIONALLY OMITTED]

     7.4  RELATED PARTY AGREEMENTS.  All Related Party Agreements, other
than those listed on SCHEDULE 7.4, will be terminated at the Closing by the
Company and/or Shareholder parties thereto.  Reasonably promptly following the
Closing and at the expense of CCC, the Shareholders shall, if requested by CCC,
direct a third party, which shall be reasonably acceptable to CCC, to evaluate
if the rents with respect to each lease that is a Related Party Agreement (other
than those listed on SCHEDULE 7.4) are greater than those  for comparably
situated properties in the same geographic market as of the date the Related
Party Agreement was entered into or as of the date of such evaluation.  To the
extent that such third party reasonably determines that the rents payable with
respect to any such lease are 25% or more than for comparably situated
properties both as of the date the Related Party Agreement was entered into and
the date of the evaluation, the parties will negotiate in good faith to adjust
such rents to market rates.

     7.5  COOPERATION.

          (a)  The Company, the Shareholders, CCC and Newco shall each deliver
or cause to be delivered to the other on the Closing Date, and at such other
times and places as shall be reasonably agreed to, such instruments as the other
may reasonably request for the purpose of carrying out this Agreement. In
connection therewith, if required, the president or chief financial officer of
the Company shall execute any documentation reasonably required by CCC's
Accountant (in connection with such accountants' audit or review of the Company)
or the Nasdaq National Market.

          (b)  The Shareholders and the Company shall cooperate and use their
reasonable efforts to have the present officers, directors and employees of the
Company cooperate with CCC on and after the Closing Date in furnishing
information, evidence, testimony and other assistance in connection with any
filing obligations, actions, proceedings, arrangements or disputes of any nature
with respect to matters pertaining to all periods prior to the Closing Date.

          (c)  Each party hereto shall cooperate in attempting to obtain all
consents and approvals that are required under this Agreement to effect the
transactions contemplated hereby or that

                                       30
<PAGE>

are advisable in order that any Material Contract remain in effect after the
Merger and without giving rise to any right to termination, cancellation or
acceleration or loss of any right or benefit. In addition, each party hereto
shall otherwise use their best efforts to consummate the transaction
contemplated hereby and to fulfill their obligations under this Agreement. The
Company and the Shareholders and Newco and CCC shall each diligently make, and
cooperate with the other in using their best efforts (excluding out of pocket
expenditures) to obtain or cause to be obtained prior to the Closing Date all
such consents without any change in the terms or conditions of any contract or
license that could reasonably be expected to be materially less advantageous to
the Surviving Corporation than those pertaining under the contract or license as
in effect on the date of this Agreement. The Company and Shareholders shall
advise CCC and Newco of any difficulties experienced in obtaining any of the
consents and of any conditions proposed, considered, or requested for any of the
consents. CCC and Newco agree to use their best efforts to assist the Company
and Shareholders in obtaining such consents, and to take such reasonable actions
necessary or desirable to obtain such consents, including without limitation,
executing such instruments and other documents as may be required in connection
with obtaining such consents.

          (d)  The Company, the Shareholders and CCC shall file any information
and documents that remain to be filed under the HSR Act as promptly as
practicable at such time as such items are required to be filed.  The Parties
hereby agree to (a) cooperate with each other in connection with such HSR Act
filings, which cooperation shall include furnishing the other with any
information or documents that may be reasonably required in connection with such
filings; (b) promptly file, after any request by the Federal Trade Commission
("FTC") or Department of Justice ("DOJ") and after appropriate negotiation with
the FTC or DOJ of the scope of such request, any information or documents
requested by the FTC or DOJ; and (c) furnish each other with any correspondence
from or to, and notify each other of any other communications with, the FTC or
DOJ that relates to the transactions contemplated hereunder, and to the extent
practicable, to permit each other to participate in any conferences with the FTC

     7.11 CCC STOCK OPTIONS.  CCC shall make available to the Surviving
Corporation for distribution at the discretion of the President of the Surviving
Corporation options to purchase up to 250,000 shares of CCC Common Stock to be
granted to the key employees of the Surviving Corporation (who were not, unless
otherwise approved by CCC,  Shareholders) on or shortly after the Closing in
accordance with CCC's policies and under the terms of CCC's 1997 Long-Term
Incentive Plan.   The exercise price of such options shall be equal to the fair
market value of the underlying shares of CCC Common Stock on the date of grant
and such options shall have vesting provisions established by the Compensation
Committee of the Board of Directors of CCC.  The options issued under the terms
of this Section 7.11 shall be nonqualified stock options that shall become
exercisable over no more than a four year period with at least 25% of such
options vesting each year (with the four year period commencing on the Closing
Date) and shall expire on the tenth anniversary of the date of grant provided
the optionee is still an employee.  The shares of CCC Common Stock underlying
such options shall be registered under the 1933 Act and approved for listing on
Nasdaq.

     7.12 TAX COVENANT.  CCC, Newco and the Company shall treat the Merger
for income tax purposes as a reorganization within the meaning of Section 368(a)
of the Code and any comparable state or local tax statute.

CCC, Newco, the Shareholders and the Company will each use their best efforts to
cause the Merger to qualify, and prior to the Effective Time and on and after
the Closing Date, will refrain from taking any actions that would

                                       35
<PAGE>

result in the Merger failing to qualify, as a reorganization as defined under
Code Section 368(a)(1)(A) and Section 368(a)(2)(D). After the Effective Time,
CCC, Newco, the Shareholders and the Company will refrain from taking any
actions that would cause the stock paid to the Shareholders pursuant to Section
2.3 of this Agreement to be taxable to the Shareholders upon receipt.

     7.14 D&O INSURANCE AND INDEMNIFICATION OF DIRECTORS AND OFFICERS.  All
rights to indemnification for acts or omissions occurring prior to the Closing
now existing in favor of the current or former directors, officers, employees or
agents of the Company required by applicable law, under the Company's Charter
Documents, or any other agreement between any such director, officer, employee
or agent of the Company and the Company and any other now existing obligation of
the Company to indemnify directors or officers for acts or omissions occurring
prior to the Closing shall survive the Merger and shall continue in full force
and effect in accordance with their terms for a period of not less than six (6)
years from the Effective Time and, to the extent the Surviving Corporation fails
to perform its obligations with respect thereto, CCC shall perform such
obligations.  In addition, CCC will provide to each director and officer of the
Surviving Corporation, during the term of his service, D&O insurance having
coverage at least as comprehensive as the D&O insurance currently maintained by
CCC.

     7.15 GOVERNMENT CONTRACTS.  To the extent applicable, it is the
intention of the Company to transfer to Newco and novate the government
contracts listed on SCHEDULE 5.19 and to obtain the required governmental
recognition of Newco as the Company's successor in interest to such government
contracts.  Recognizing that applicable government regulations may not permit
the Company to transfer the Company's government contracts and obtain novation
of those contracts prior to the Closing, the Company and Newco agree to
cooperate and diligently pursue contract novation pursuant to applicable and
required government procedures.

     7.16 CCC STOCK.  Between the date of this Agreement and the Effective
Time, CCC shall not declare, pay or set aside any dividend or other distribution
(whether in cash, stock or property or any combination thereof) in respect of
its equity securities or directly or indirectly redeem, purchase or otherwise
acquire or offer to acquire any shares of its equity securities, other than any
such action which would not result in any adjustment to the Base Merger
Consideration or the Contingent Merger Consideration pursuant to Section 2.2(b)
and 2.3(e).

     7.17 EMPLOYEE BENEFITS MATTERS.   For the twelve month period
commencing as of the Closing Date, CCC and any successor thereto shall continue
to maintain all Plans maintained by the Company as of the Closing Date for the
benefit of all employees of CCC or any entity related to CCC under the terms of
Code Sections 414(b), (c), (m) or (o) who are engaged in the performance of
services with respect to the business conducted by the Company prior to the
Closing Date. Any amendment, modification, or termination of any Plan of the
Company maintained by CCC or its successor during any period such Plan is
required to be maintained in accordance with this Section 7.16 shall only be
made if CCC and the president of the Surviving Corporation or his successor, in
his capacity as an employee of CCC or any affiliate thereof, shall mutually
agree to such amendment, modification, or termination.

     7.18 GUARANTEED DEBT.  It is understood and agreed that the
Shareholders will seek to have all personal guarantees (by pledge of assets or
otherwise) of any Shareholder released in connection with consummation of the
Merger and that CCC will cooperate with the Shareholders in such effort.
Following the Closing CCC will not and will cause the Surviving Corporation not
to draw under any line of credit or other indebtedness the repayment of which
has been personally guaranteed by a Shareholder

                                       36
<PAGE>

(by pledge of assets or otherwise) unless and until such personal guarantee
(including any pledge of assets) has been fully released.

     7.19 REPAYMENT OF RECEIVABLE. On or before the 180th day immediately
following the Closing CCC shall cause the Surviving Corporation to repay in full
all amounts then outstanding under the Walker Note described on Schedule 5.8
hereto.

                                                      -----------------
Claim against any party obligated to provide indemnification pursuant to this
Article 10  (individually and collectively, the "Indemnifying Party") which does
                                                 ------------------
not involve a Claim being asserted against or sought to be collected by a third
party, the Indemnified Party shall with reasonable promptness notify the
Indemnifying Party of such Claim, specifying the nature of such Claim and the
amount or the estimated amount thereof to the extent then feasible (the "Claim
                                                                         -----
Notice").  If the Indemnifying Party does not notify the Indemnified Party
------
within thirty days after the date of delivery of the Claim Notice that the
Indemnifying Party disputes such Claim, with a statement of the basis of such
position, the amount of such Claim shall be conclusively

                                       42
<PAGE>

deemed a liability of the Indemnifying Party hereunder. In case an objection is
made in writing in accordance with this Section 10.4(a), the Indemnified Party
shall respond in a written statement to the objection within thirty days and,
for sixty days thereafter, attempt in good faith to agree upon the rights of the
respective parties with respect to such Claim (and, if the parties should so
agree, a memorandum setting forth such agreement shall be prepared and signed by
both parties).

          (b)  (i) In the event that any Claim for which the Indemnifying
Party would be liable to an Indemnified Party hereunder is asserted against an
Indemnified Party by a third party (a "Third Party Claim"), the Indemnified
                                       -----------------
Party shall deliver a Claim Notice including a copy of the claim if such claim
was made in writing to the Indemnifying Party. The Indemnifying Party shall have
thirty days from the date of delivery of the Claim Notice to notify the
Indemnified Party (A) whether the Indemnifying Party disputes liability to the
Indemnified Party hereunder with respect to the Third Party Claim, and, if so,
the basis for such a dispute, and (B) if such party does not dispute liability,
whether or not the Indemnifying Party desires, at the sole cost and expense of
the Indemnifying Party, to defend against the Third Party Claim, provided that
the Indemnified Party is hereby authorized (but not obligated) to file any
motion, answer or other pleading and to take any other action which the
Indemnified Party shall deem necessary or appropriate to protect the Indemnified
Party's interests.

               (ii)  In the event that the Indemnifying Party timely notifies
the Indemnified Party that the Indemnifying Party does not dispute the
Indemnifying Parties' obligation to indemnify with respect to the Third Party
Claim, the Indemnifying Party shall defend the Indemnified Party against such
Third Party Claim by appropriate proceedings, provided that, unless the
Indemnified Party otherwise agrees in writing, the Indemnifying Party may not
settle any Third Party Claim (in whole or in part) if such settlement does not
include a complete and unconditional release of the Indemnified Party. If the
Indemnified Party desires to participate in, but not control, any such defense
or settlement the Indemnified Party may do so at its sole cost and expense. The
Indemnified Party shall cooperate with the Indemnifying Party's defense against
any third-party claim. If the Indemnifying Party elects not to defend the
Indemnified Party against a Third Party Claim, whether by failure of such party
to give the Indemnified Party timely notice as provided herein or otherwise,
then the Indemnified Party, without waiving any rights against such party, may
settle or defend against such Third Party Claim in the Indemnified Party's sole
discretion and the Indemnified Party shall be entitled to recover from the
Indemnifying Party the amount of any settlement or judgment and, on an ongoing
basis, all indemnifiable costs and expenses of the Indemnified Party with
respect thereto, including interest from the date such costs and expenses were
incurred.

               (iii) If at any time, in the reasonable opinion of the
Indemnified Party, notice of which shall be given in writing to the Indemnifying
Party, any Third Party Claim seeks material prospective relief which could have
an adverse effect on the assets, liabilities, financial condition or results of
operations of the Indemnified Party (or on the Surviving Corporation but only if
the Indemnified Party is CCC and/or Newco in such an instance), the Indemnified
Party shall have the right to control or assume (as the case may be) the defense
of any such Third Party Claim; provided, however, that the Indemnified Party
will not settle any such Third Party Claim without the prior consent of the
Indemnifying Party, which consent shall not be unreasonably withheld.  If the
Indemnified Party elects to exercise such right, the Indemnifying Party shall
have the right to participate in, but not control, the defense of such Third
Party Claim at the sole cost and expense of the Indemnifying Party.

          (c)  Subject to the provisions of Section 10.3, the Indemnified
Party's failure to give reasonably prompt notice as required by this Section
10.4 of any actual, threatened or possible claim or

                                       43
<PAGE>

demand which may give rise to a right of indemnification hereunder shall not
relieve the Indemnifying Party of any liability which the Indemnifying Party may
have to the Indemnified Party unless the failure to give such notice materially
and adversely prejudices the Indemnifying Party.

          (d)  The parties will make appropriate adjustments for any Tax
benefits, Tax detriments or insurance proceeds in determining the amount of any
indemnification obligation under this Article 10, provided that the Indemnified
Party shall be obligated to make reasonable efforts to continue pursuing any
payment pursuant to the terms of any insurance policy or to assign its rights
under such policy to the Indemnifying Party.

     10.5 SURVIVAL OF REPRESENTATIONS WARRANTIES.  The representations of
each of the Company, the Shareholders, CCC and Newco will survive the Closing
until, and will expire upon, the termination of the indemnification obligations
as provided in Section 10.3(e).

     10.6 RIGHT TO SET OFF.  CCC shall have the right, but not the
obligation, to set off, in whole or in part, against the Pledged Assets, amounts
finally determined under Section 10.4 to be owed to CCC by the Shareholders
under Section 10.1 hereof.


11.  NONCOMPETITION

     11.1 PROHIBITED ACTIVITIES.  Except as described on SCHEDULE 11.1
hereto or as otherwise provided in an employment agreement with CCC or a
subsidiary of CCC, the Surviving Corporation or any other subsidiary of CCC,
each Shareholder agrees that for a period of two years following the Closing
Date, he/she shall not:

          (a)  engage, as an officer, director, shareholder, owner, partner,
member, joint venturer, or in a managerial capacity, whether as an employee,
independent contractor, consultant, advisor, or sales representative, in any
electrical contracting (including, without limitation, construction, maintenance
and/or design) business selling any products or services in direct competition
with CCC or any of its subsidiaries within 100 miles of any office of CCC or any
office of any of its subsidiaries (the "Territory");
                                        ---------

          (b)  call upon any person who is, at that time, within the Territory,
an employee of CCC or any subsidiary of CCC in a managerial capacity for the
purpose or with the intent of enticing such employee away from or out of the
employ of CCC or any subsidiary of CCC;

          (c) call upon any person within the Territory who is, at that time, or
has been, within one year prior to that time, a customer of CCC or any
subsidiary of CCC, for the purpose of soliciting or selling products or services
in direct competition with CCC or any subsidiary of CCC within the Territory;

          (d)  call upon any person who is, at the time, or has been, within one
year prior to that time, a customer of CCC and/or any subsidiary or affiliate of
CCC with whom the Shareholder has had personal contact for the purpose of
soliciting or selling products or services in direct competition with CCC and/or
any subsidiary or affiliate of CCC; or

          (e)  on the Shareholder's behalf or on behalf of any competitor, call
upon any person as a prospective acquisition candidate who was, to the
Shareholder?s knowledge, either called upon by

                                       44
<PAGE>

CCC or a subsidiary of CCC as a prospective acquisition candidate or was the
subject of an acquisition analysis by CCC or any subsidiary of CCC. The
Shareholder, to the extent lacking the knowledge described in the preceding
sentence, shall immediately cease all contact with any prospective acquisition
candidate upon being informed, in writing, that CCC or any subsidiary of CCC had
so called upon such candidate or made an acquisition analysis thereof.

     Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit any Shareholder subject to this Article 11 from acquiring as an
investment not more than one percent of the outstanding voting capital stock of
a competing business, whose stock is traded on a national securities exchange or
through the automated quotation system of a registered securities association.

     11.2 DAMAGES.  Because of the difficulty of measuring economic losses
to CCC and the Surviving Corporation as a result of the breach of the foregoing
covenant, and because of the immediate and irreparable damage that would be
caused to CCC and the Surviving Corporation for which they would have no other
adequate remedy, each Shareholder subject to this Article 11  agrees that, in
the event of a breach by them of the foregoing covenant, the covenant may be
enforced by CCC or the Surviving Corporation by, without limitation, injunctions
and restraining orders.

     11.3 REASONABLE RESTRAINT.  It is agreed by the parties that the
foregoing covenants in this Article 11 impose a reasonable restraint on the
Shareholders subject to this Article 11 in light of the activities and business
of CCC on the date of the execution of this Agreement and the current and future
plans of CCC and the Surviving Corporation (as successors to the businesses of
the Company).

     11.4 SEVERABILITY; REFORMATION.  The covenants in this Article 11 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant.  Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

     11.5 INDEPENDENT COVENANT.  All of the covenants in this Article 11
shall be construed as an agreement independent of any other provision of this
Agreement, and the existence of any claim or cause of action of the Shareholders
against the Company, the Surviving Corporation or CCC, whether predicated on
this Agreement or otherwise, shall not constitute a defense to the enforcement
of such covenants.  It is specifically agreed that the period of two years
stated above, shall be computed by excluding from such computation any time
during which any Shareholder subject to this Article 11 is in violation of any
provision of this Article 11 and any time during which there is pending in any
court of competent jurisdiction any action (including any appeal from any
judgment) brought by any person, whether or not a party to this Agreement, in
which action CCC or the Surviving Corporation seeks to enforce the agreements
and covenants of the Shareholders set forth in this Article 11 or in which any
person contests the validity of such agreements and covenants or their
enforceability or seeks to avoid their performance or enforcement; provided,
however, that if any Shareholder is found not to be in violation of the
agreements or covenants in any such activity the period during which the action
was pending shall not be excluded from such computation.

     11.6 MATERIALITY.  CCC, the Company and each Shareholder hereby agree
that the covenants set forth in this Article 11 are a material and substantial
part of the transactions contemplated by this Agreement, and that no portion of
the Base Merger Consideration or the Contingent Merger Consideration shall be
paid for or allocated to the covenants set forth in this Article 11.

12.  NONDISCLOSURE OF CONFIDENTIAL INFORMATION

     12.1 CONFIDENTIALITY.

          (a)  None of the parties hereto will use or disclose to third parties
(except as may be necessary for the consummation of the transactions
contemplated hereby, or as required by law, including, without limitation, in
connection with legal proceedings relating to this Agreement and the
transactions contemplated hereby, or otherwise pursuant to subpoena or the
request of a governmental authority, and then only with prior notice to the
other parties hereto, including delivery of a copy of the subpoena or request,
if applicable) this Agreement, any information (including, without limitation,
financial information) received from any other party hereto or its agents in the
course of investigating, negotiating and performing the transactions
contemplated by this Agreement or any confidential information of the Company or
the Surviving Corporation received or that any such party receives in the future
relating to the Company or the Surviving Corporation (such as lists of
customers, operational policies and pricing and cost policies that are valuable,
special and unique assets of the Company or the Surviving Corporation or the
business of the Company or the Surviving Corporation; provided, however, that
each party may disclose such information to such party's officers, directors,
employees, lenders, advisors, attorneys and accountants who need to know such
information in connection with the consummation of the transactions contemplated
by this Agreement and who are informed by such party of the confidential nature
of such information.  Nothing shall be deemed to be confidential information
that:  (1) is already in such party's possession, provided that such information
is not known by such party to be subject to another confidentiality agreement
with or other obligation of secrecy to the other party hereto or another party,
or (2) becomes generally available to the public other than as a result of a
disclosure by such party or such party's officers, directors, employees,
lenders, advisors, attorneys or accountants, or (3) becomes available to such
party on a non-confidential basis from a source other than the other party
hereto or its advisors, provided that such source is not known by such party to
be bound by a confidentiality agreement with or other obligation of secrecy to
the other party hereto or another party, or (4) is developed independently by
either party without resort to the confidential information of the other party.
In the event this Agreement is terminated and the transactions contemplated
hereby abandoned, each party will return to the other party all written
confidential information (including all documents, work papers and other written
confidential material) obtained by the such party from any other party, or
developed by such party based on confidential information, in connection with
the transactions contemplated by this Agreement.

          (b)  No party shall publish any press release or make any other public
announcement concerning this Agreement or the transactions contemplated hereby
without the prior written consent of each other party, which shall not be
withheld unreasonably; provided, however, that nothing contained in this
Agreement shall prevent any party, after notification to each other party, from
making any filings with governmental authorities that, in its judgment, may be
required or advisable in connection with the execution and delivery of this
Agreement or the consummation of the transactions contemplated hereby.

     12.2 DAMAGES.  Because of the difficulty of measuring economic losses
as a result of the breach of the foregoing covenants, and because of the
immediate and irreparable damage that would be caused for which they would have
no other adequate remedy, CCC, the Surviving Corporation and the Shareholders
agree that, in the event of a breach by any of them of the foregoing covenant,
the covenant may be enforced against them by injunctions and restraining orders.
Nothing herein shall be construed

                                       46
<PAGE>

as prohibiting any party from pursuing any other available remedy for such
breach or threatened breach, including the recovery of damages.

13.  GENERAL

     13.1 TERMINATION.  This Agreement may be terminated at any time prior
to the Closing Date solely:

          (a)  by mutual written consent of the Boards of Directors of CCC
and the Company; or

          (b)  by the holders of a majority of the voting stock of the Company
and the Company as a group on the one hand, or by CCC, on the other hand, if the
Closing shall not have occurred on or before April 30, 1998, provided that the
right to terminate this Agreement under this Section 13.1(b) shall not be
available to either party (with the Shareholders and the Company deemed to be a
single party for this purpose) whose material misrepresentation, breach of
warranty or failure to fulfill any obligation under this Agreement has been the
cause of, or resulted in, the failure of the Closing to occur on or before such
date; or

          (c)  by the holders of a majority of the voting stock of the Company
and the Company as a group on the one hand, or by CCC, on the other hand, if
there is or has been a material breach, failure to fulfill or default on the
part of the other party (with the Shareholders and the Company deemed to be a
single party for this purpose) of any of the representations and warranties
contained herein or in the due and timely performance and satisfaction of any of
the covenants, agreements or conditions contained herein, and the curing of such
default shall not have been made on or before the Closing Date; or

          (d)  by the holders of a majority of the voting stock of the Company
and the Company as a group on the one hand, or by CCC, on the other hand, if
there shall be a final nonappealable order of a federal or state court in effect
preventing consummation of the Merger; or there shall be any action taken, or
any statute, rule or regulation or order enacted, promulgated or issued or
deemed applicable to the Merger by any governmental entity which would make the
consummation of the Merger illegal; or

     13.2 EFFECT OF TERMINATION.  (a)  In the event of termination of this
Agreement by either or both of CCC and/or the holders of the majority of the
voting stock of the Company and the Company (with such Shareholders and the
Company deemed to be a single party for purposes of this Section 13.2) pursuant
to Section 13.1, prompt written notice thereof shall forthwith be given to the
other party and this Agreement shall terminate and the transactions contemplated
hereby shall be abandoned without further action by any of the parties hereto,
but subject to and without limiting any of the rights of the parties specified
herein in the event a party is in default or breach in any material respect of
its obligations under this Agreement.  If this Agreement is terminated as
provided herein:

               (i)   None of the parties hereto nor any of their respective
partners, directors, officers, shareholders, employees, agents, or affiliates
shall have any liability or further obligation hereunder except with respect to
Article 12 and Article 13; and

                                       47
<PAGE>

              (ii)   All filings, applications and other submissions relating
to the transactions contemplated hereby as to which termination has occurred
shall, to the extent practicable, be withdrawn from the agency or other person
to which made.

          (b)  (i)   If this Agreement is terminated pursuant to Section
13.1 and  any party shall be in material breach of any of its obligations,
representations, warranties or covenants set forth in this Agreement, the other
party shall have the right to pursue all legal or equitable remedies for breach
of contract or otherwise, and

              (ii)   Without limiting the generality of the foregoing, or any
applicable law, neither CCC and Newco, on the one hand, nor the Company and the
Shareholders, on the other hand, may rely on the failure of any condition
precedent set forth in Articles 8 and 9 to be satisfied as a ground for
termination of this Agreement by such party if such failure was caused by such
party's (or parties') failure to act in good faith, or a breach of or failure to
perform its representations, warranties, covenants or other obligations in
accordance with the terms hereof.

     13.3 SUCCESSORS AND ASSIGNS.  This Agreement and the rights of the
parties hereunder may not be assigned (except by operation of law) and shall be
binding upon and shall inure to the benefit of the parties hereto, the
successors of CCC and the other parties hereto, and the heirs and legal
representatives of the Shareholders.

     13.4 ENTIRE AGREEMENT; AMENDMENT; WAIVER.  This Agreement sets forth
the entire understanding of the parties hereto with respect to the transactions
contemplated hereby. Each of the Schedules to this Agreement is incorporated
herein by this reference and expressly made a part hereof. Any and all previous
agreements and understandings between or among the parties regarding the subject
matter hereof, whether written or oral, are superseded by this Agreement. This
Agreement shall not be amended or modified except by a written instrument duly
executed by each of the parties hereto.  Any extension or waiver by any party of
any provision hereto shall be valid only if set forth in an instrument in
writing signed on behalf of such party.

     13.5 COUNTERPARTS.  This Agreement may be executed in any number of
counterparts and any party hereto may execute any such counterpart, each of
which when executed and delivered (which deliveries may be made by telefax)
shall be deemed to be an original, and all of which counterparts taken together
shall constitute but one and the same instrument.

     13.6 BROKERS AND AGENTS.  CCC and Newco (as a group) and the Company
and each Shareholder (as a group) each represents and warrants to the other that
except as set forth in SCHEDULE 13.6, it/they has/have not employed any broker
or agent in connection with the transactions contemplated by this Agreement and
agrees to indemnify the other against all losses, damages or expenses relating
to or arising out of claims for fees or commission of any broker or agent
employed or alleged to have been employed by such party.

     13.7 EXPENSES.  CCC has paid and will pay the fees, expenses and
disbursements of CCC and Newco and their agents, representatives, accountants
and counsel incurred in connection with the subject matter of this Agreement.
The Shareholders (and not the Company) have paid and will pay the fees, expenses
and disbursements of the Shareholders, the Company, and their agents,
representatives, financial advisers, accountants and counsel incurred in
connection with the subject matter of this Agreement.  It is agreed that the
fees and expenses relating to any HSR Act filing will be split between CCC on
the one hand and the Shareholders on the other.  At the election of the
Shareholders, any of the foregoing

                                       48
<PAGE>

fees contemplated under this SECTION 13.7 payable by them will be paid by CCC or
the Company and not the Shareholders, provided that the aggregate amount of the
Base Merger Consideration is reduced by the amount of such expenses with any
such reduction to have no effect on the calculation of the Actual Earn Out EBIT
or the payment of the Contingent Merger Consideration.

     13.8 SPECIFIC PERFORMANCE; REMEDIES.  Each party hereto acknowledges
that the other parties will be irreparably harmed and that there will be no
adequate remedy at law for any violation by any of them of any of the covenants
or agreements contained in this Agreement, including without limitation, the
noncompetition provisions set forth in Article 11 and the confidentiality
obligations set forth in Article 12. It is accordingly agreed that, in addition
to any other remedies which may be available upon the breach of any such
covenants or agreements, each party hereto shall have the right to obtain
injunctive relief to restrain a breach or threatened breach of, or otherwise to
obtain specific performance of, the other parties, covenants and agreements
contained in this Agreement.
