shares under the DGCL shall effectively withdraw or lose (through failure to
perfect or otherwise) such holder's appraisal rights, then, as of the later of
(A) the Effective Time or (B) the occurrence of such event, such holder's shares
of Company Common Stock shall automatically be converted into and represent only
the right to receive Merger Consideration as provided in Section 1.2(b), without
interest thereon, upon surrender of the Certificate representing such shares.

                  (iii)  The Company shall give Parent (A) prompt notice of its
receipt of any written demands for appraisal of any shares of Company Common
Stock, withdrawals of such demands, and any other instruments relating to the
Merger served pursuant to the DGCL and received by the Company and (B) the
opportunity to direct all negotiations and proceedings with respect to demands
for appraisal of any shares of Company Common Stock under the DGCL. The Company
shall not, except with the prior written consent of Parent or as may be required
under applicable law (in which case Parent shall be consulted), voluntarily make
any payment with respect to any demands for the appraisal of Company Common
Stock or offer to settle or settle any such demands or approve any withdrawal of
such demands.

            (d)   Closing of the Company's Transfer Books. At the Effective
                  ---------------------------------------
Time, the stock transfer books of the Company shall be closed and no transfer of
Company Common Stock shall thereafter be made. If, after the Effective Time,
Certificates are presented to the Surviving Corporation, they shall be cancelled
and exchanged for Merger Consideration as provided in this Article I, subject to
applicable law in the case of Dissenting Shares.

            (e)   Conversion of Common Stock of Merger Sub. Each share of common
                  ----------------------------------------
stock, $0.01 par value, of Merger Sub issued and outstanding immediately prior
to the Effective Time shall remain issued and outstanding and shall constitute a
share of common stock of the Surviving Corporation.

     Section 1.3  Exchange of Certificates.
                  ------------------------

            (a)   Prior to the mailing of the Proxy Statement (as defined in
Section 5.3(b) hereof) a bank, trust company or other person, reasonably
acceptable to the Company, shall be designated by Parent to act as the
depositary and paying agent for the delivery of the Merger Consideration in
exchange for shares of Company Common Stock (the "Paying Agent") in connection
with the Merger. From time to time, as necessary, at or following the Effective
Time, Parent shall deposit, or cause to be deposited, with the Paying Agent the
amount needed to pay the

                                      -5-
<PAGE>

portion of the aggregate Merger Consideration for the benefit of the holders of
shares of Company Common Stock which are converted into the right to receive
Merger Consideration pursuant to Section 1.2(b) hereof for which Certificates
have been surrendered or payment is otherwise due (the "Exchange Fund"). For
purposes of this Agreement, "person" means any natural person, firm, individual,
corporation, limited liability company, partnership, association, joint venture,
company, business trust, trust or any other entity or organization, whether
incorporated or unincorporated, including a government or political subdivision
or any agency or instrumentality thereof.

          (b)  As of or promptly following the Effective Time, the Surviving
Corporation shall cause the Paying Agent to mail to each holder of record of a
certificate or certificates, which immediately prior to the Effective Time
represented outstanding shares of Company Common Stock (other than Dissenting
Shares) (the "Certificates"), (i) a letter of transmittal (which shall specify
that delivery shall be effected, and risk of loss and title to the Certificates
shall pass, only upon proper delivery of the Certificates to the Paying Agent
and which shall be in the form and have such other provisions as Parent and the
Company may reasonably specify) and (ii) instructions for use in effecting the
surrender of the Certificates in exchange for the Merger Consideration into
which the number of shares of Company Common Stock previously represented by
such Certificate shall have been converted into the right to receive pursuant to
this Agreement (which instructions shall provide that, at the election of the
surrendering holder, Certificates may be surrendered, and the Merger
Consideration in exchange therefor collected, by hand delivery). Upon surrender
of a Certificate for cancellation to the Paying Agent, together with a letter of
transmittal duly completed and validly executed in accordance with the
instructions thereto, and such other documents as may be required pursuant to
such instructions, the holder of such Certificate shall be entitled to receive
in exchange therefor the Merger Consideration for each share of Company Common
Stock formerly represented by such Certificate, to be mailed (or made available
for collection by hand if so elected by the surrendering holder) within three
business days of receipt thereof (but in no case prior to the Effective Time),
and the Certificate so surrendered shall be forthwith cancelled. The Paying
Agent shall accept such Certificates upon compliance with such reasonable terms
and conditions as the Paying Agent may impose to effect an orderly exchange
thereof in accordance with normal exchange practices.

          (c)  Any portion of the Exchange Fund which remains undistributed to
the holders of Certificates for six months after the Effective Time shall be
delivered to Parent, upon demand, and any holders of shares of Company Common
Stock prior to the Merger who have not theretofore complied with this Article I
shall thereafter look for payment of their claim, as general creditors thereof,
only to Parent for their claim for Merger Consideration, without interest.

          (d)  None of Parent, the Company or the Paying Agent shall be liable
to any person in respect of any Merger Consideration held in the Exchange Fund
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law. If any Certificates shall not have been surrendered
prior to one year after the Effective Time (or immediately prior to such earlier
date on which Merger Consideration in respect of such Certificate would
otherwise escheat to or become the property of any Governmental Entity (as
defined in Section 3.3(b) hereof)), any such Merger Consideration in respect of
such Certificate shall, to the extent permitted by applicable law, become the
property of Parent, free and clear of all claims or interest of any person
previously entitled thereto.

     Section 1.4  Company Options; Company Warrants.
                  ---------------------------------

             (a)  Not later than fifteen days (15) prior to the Effective Time,
the Company shall send a notice (the "Option Notice") to all holders of options
to purchase Company Common Stock (the "Company Options"): (i) specifying that
such options shall not be assumed in connection with the Merger, (ii) specifying
that the vesting restrictions applicable to all options to purchase Company
Common Stock outstanding at the time of such notice shall be eliminated such
that no vesting restrictions remain thereon effective as of the date such notice
is given, (iii) specifying that any Company Options outstanding as of the
Effective Time shall terminate and be cancelled at such time and represent only
the right to receive the consideration, if any, specified in Section 1.4(c) in
accordance with this Agreement, (iv) setting forth an estimate of the Merger
Consideration and (v) setting forth a description of how to determine an
estimate of the excess, if any, of the exercise price per share of such Company
Options over the estimated Merger Consideration (the "Estimated Exercise
Payment"). Except as expressly provided herein, the Company shall not adjust the
terms of any Company Option as a result of the Distribution.

            (b)   The Company shall permit each holder of a Company Option who
desires to exercise all or any portion of such Company Option following receipt
of the Option Notice to exercise such Company Option (A) immediately prior to
the record date with respect to the Distribution or (B) after the record date
with respect to the Distribution but immediately prior to the Effective Time or
(C) at any other time permitted under the applicable Company Option.  In the
event any such holder exercises all or any portion of a Company Option as
provided in clause (A) or (B) of the immediately preceding sentence, (i) the
holder shall be permitted to cause the Company to withhold the exercise price
with respect to such exercise out of the Merger Consideration (to the extent
thereof) to be received by such holder in respect of the shares of Common Stock
acquired pursuant to such exercise and (ii) the holder shall be obligated to pay
in cash to the Company, at the time of exercise, the Estimated Exercise Payment.
Any Company Common Stock issuable upon the exercise of Company Options as
provided in clause (A) or (B) of the first sentence of this paragraph shall by
virtue of the Merger, and without any action on the part of the holder thereof,
be converted into the right to receive the Merger Consideration payable in
respect thereof (net of any exercise price withholding obligation, as herein
provided), without the issuance of certificates representing issued and
outstanding shares of Company Common Stock; provided, that any Company Common
                                            --------  ----
Stock issuable upon the exercise of Company Options as provided in clause (A) of
the first sentence of this paragraph shall be deemed issued and outstanding on
the record date with respect to the Distribution; and provided, further that any
                                                      --------  -------
Company Common Stock issuable upon the exercise of Company Options as provided
in clause (A) or (B) of the first sentence of this paragraph shall be deemed to
be issued and outstanding as of the Effective Time.  After the Effective Time,
the Company shall determine the actual amount of the excess, if any, of the
exercise price of each Company Option over the actual Merger Consideration (the
"Actual Exercise Payment"), with respect to the Company Options exercised
pursuant to clauses (A) or (B) of the first sentence of this paragraph.  To the
extent that the Actual Exercise Payment exceeds the Estimated Exercise Payment
made by any holder of a Company Option with respect to the shares of Company
Common Stock deemed issued pursuant to exercise, the Company shall notify such
party that a payment is due from such holder to the Company in the amount of the
excess of the Actual Exercise Payment over the Estimated Exercise Payment.  The
Company shall retain any Distribution to be made to a holder of Company Options
who must make a payment to the Company in accordance with the immediately

                                      -7-
<PAGE>

preceding sentence of this paragraph as security for such payment.  To the
extent that the Estimated Exercise Payment made by a holder of a Company Option
exceeds the Actual Exercise Payment, the Company shall, or shall cause the
Paying Agent to, pay such holder the excess of the Estimated Exercise Payment
over the Actual Exercise Payment, on or about the time of the payment of the
Merger Consideration.

          (c)  All Company Options outstanding as of the Effective Time shall by
virtue of the Merger, and without any action on the part of the holder thereof,
be terminated and cancelled as of the Effective Time and converted into, and
represent only, the right to receive an amount in cash equal to the excess, if
any, of (i) the product of the Merger Consideration multiplied by the number of
shares of Company Common Stock subject to such Company Options immediately prior
to the Effective Time over (ii) the aggregate exercise price of all such shares
of Company Common Stock subject to such Company Option.  The  aggregate amount
payable pursuant to this paragraph (c) shall hereinafter be referred to as the
"Option Cash-Out Amount."

          (d)  Not later than fifteen days (15) prior to the record date for the
Distribution, the Company shall, in accordance with Section 5 thereof, deliver a
notice to the holder of the Stock Purchase Warrant, dated July 31, 1997, between
Glaxo and the Company (the "Company Warrant"). The Company shall permit the
holder of the Company Warrant to exercise all or any portion of such Company
Warrant at any time permitted thereunder. At the Effective Time, the Company
Warrant shall, by virtue of the Merger and without any action on the part of the
holder thereof, be converted into, and represent only, the right to receive,
upon delivery thereof to the Company, an amount in cash equal to the excess, if
any, of (i) the product of the Merger Consideration multiplied by the number of
shares of Company Common Stock subject to such Company Warrant immediately prior
to the Effective Time over (ii) the aggregate exercise price of all such shares
of Company Common Stock subject to such Company Warrant. The aggregate amount
payable pursuant to this paragraph (d) shall hereinafter be referred to as the
"Warrant Cash-Out Amount."

          (e)  Exchange Procedures for Company Options or Company Warrant.
               ----------------------------------------------------------
Promptly following the Effective Time, Parent shall cause the Paying Agent to
mail to each holder (as of the Effective Time) of a Company Option which was
converted into the right to receive the Option Cash-Out Amount pursuant to
Section 1.4(c) hereof or the Company Warrant if converted into the right to
receive the Warrant Cash-Out Amount pursuant to Section 1.4(d), (i) a letter of
transmittal (which shall be in such form and have such other provisions as
Parent may reasonably specify), and (ii) instructions for use in receiving cash
payable in respect of such Company Options or Company Warrant.  Upon the
delivery of such letter of transmittal, duly completed and validly executed in
accordance with the instructions thereto, together with the documentation
representing the Company Options or Company Warrant surrendered thereby, to the
Paying Agent, the holders of Company Options or Company Warrant shall be
entitled to receive the Option Cash-Out Amount or Warrant Cash-Out Amount
payable to them in respect of such Company Options pursuant to Section 1.4(c) or
Company Warrant pursuant to Section 1.4(d).

          (f)  Required Withholding.  The Paying Agent shall be entitled to
               --------------------
deduct and withhold from the Merger Consideration or any other consideration or
amount deliverable or otherwise payable pursuant to the Merger and this
Agreement to any holder or former holder of

                                      -8-
<PAGE>

Company Common Stock or Company Options such amounts as may be required to be
deducted or withheld therefrom under the Code or under any applicable provision
of state, local or foreign tax law or under any other applicable legal
requirement. To the extent such amounts are so deducted or withheld, such
amounts shall be treated for all purposes under this Agreement as having been
delivered or otherwise paid to the person to whom such amounts would otherwise
have been delivered or otherwise paid pursuant to the Merger and this Agreement.

     Section 1.5  Employee Stock Purchase Plan.  Immediately prior to the record
                  ----------------------------
date with respect to the Distribution, in accordance with the terms of the
Company's 1992 Employee Stock Purchase Plan (the "Company ESPP"), all rights to
purchase shares of Company Common Stock outstanding under the Company ESPP
immediately prior to such record date shall be exercised and each share of
Company Common Stock purchased pursuant to such exercise shall by virtue of the
Merger, and without any action on the part of the holder thereof, be converted
into the right to receive the Merger Consideration payable in respect thereof,
without the issuance of certificates representing issued and outstanding shares
of Company Common Stock. Any Company Common Stock issued pursuant to the Company
ESPP shall be deemed issued and outstanding at the Effective Time and on the
record date with respect to the Distribution. The Company ESPP shall be
terminated immediately following such exercises.

     Section 1.6  Distribution of the Energy Business.  It is a condition to
                  -----------------------------------
each party's obligation to consummate the Merger that, on the Closing Date and
after the satisfaction and waiver of all conditions to the Merger other than the
condition set forth in Section 6.1(d), the capital stock of Spinco held by the
Company shall, subject to the penultimate sentence in Section 1.4(b), be
distributed in its entirety to the stockholders of the Company (the
"Distribution"). The terms of the Distribution will be determined by the
Company; provided, however, that Parent's consent, which shall not be
         --------  -------
unreasonably withheld, shall be required in connection with any material
deviation from the terms and conditions of the Distribution described in
Schedule 1.6 and shall be required as to the final form of each of the specific
agreements identified in Schedule 1.6. "Spinco" shall mean the corporation whose
assets include the Energy Business. The "Energy Business" shall consist of CCSI

                  -----------------
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Surviving Corporation, the posting by such person of a bond, in such
reasonable amount as the Surviving Corporation may direct, as indemnity against
any claim that may be made against it with respect to such Certificate, the
Paying Agent will pay the Merger Consideration to which the holder thereof is
entitled pursuant to this Article I in exchange for such lost, stolen or
destroyed Certificate.

     Section 1.8  Merger Closing.  Subject to the satisfaction or waiver of the
                  --------------

     Section 1.9  Dispute Resolution.
                  ------------------

             (a)  In the event Parent and the Company disagree, prior to the
Effective Time, as to: (i) the calculation of the Cash Amount in Section 1.2(b),
(ii) whether the terms of the Distribution materially deviate from Schedule 1.6
or (iii) whether Parent's consent has been unreasonably withheld with respect to
such material deviation or the final form of any of the specific agreements
identified in Schedule 1.6, either of them may submit such dispute or
disagreement for final and binding determination to a mutually acceptable third
party arbitrator, such determination to be made within 10 days of the submission
to such arbitration by either of them.  If Parent and the Company are unable to
mutually agree upon an arbitrator within one week of a party's notification to
the other of its desire to arbitrate, then each of them shall have one week to
select an arbitrator and such two arbitrators shall have one week to select a
third arbitrator, who shall have final authority to resolve such dispute within
10 days of the selection of such arbitrator.  The parties shall share equally in
the fees and expenses of such arbitrators, and such fees and expenses shall be
paid by Spinco and Parent prior to the Effective Time.

             (b)  At least 15 days prior to the Closing Date, the Company will
provide to Parent the Company's latest estimate of the calculation of the Cash
Amount. Parent may, within 5 days of receipt of such calculation, object to the
determination of any component of the Cash Amount.  In the event that Parent and
the Company cannot reach agreement on the disputed components of the
calculation, either party may seek to resolve such dispute through the mechanism
set forth in Section 1.9(a).

                           The Surviving Corporation

     Section 2.1  Certificate of Incorporation.  At the Effective Time, the

                                  Article III

                 Representations and Warranties of the Company

     The Company represents and warrants to Parent, subject to such exceptions
as are disclosed (i) in any of the Company SEC Documents (as defined below)
filed prior to the date hereof or (ii) in writing in the disclosure letter
supplied by the Company to Parent, which disclosure shall provide an exception
to or otherwise qualify the representations or warranties of Company
specifically referred to in such disclosure and such other representations and
warranties to the extent such disclosure shall reasonably appear to be
applicable to such other representations or warranties (the "Company Disclosure
Schedule") as follows:

     Section 3.1  Corporate Existence and Power. The Company is a corporation
                  -----------------------------
duly incorporated, validly existing and in good standing under the laws of the
State of Delaware, and has all corporate powers and all governmental licenses,
authorizations, consents and approvals (collectively, "Licenses") required to
carry on its business as now conducted or presently proposed to be conducted
except for failures to have any such License which would not, in the aggregate,
have a Company Material Adverse Effect (as defined below). The Company 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, leased or operated
by it or the nature of its activities makes such qualification necessary, except
in such jurisdictions where failures to be so qualified would not reasonably be
expected to, in the aggregate, have a Company Material Adverse Effect. As used
herein, the term "Company Material Adverse Effect" means a material adverse
effect on the condition (financial or otherwise), business, assets or results of
operations of the Company and its Subsidiaries (as defined in Section 1.2(b),
taken as a whole (assuming consummation of the Distribution in accordance with
the terms of this Agreement and Schedule 1.6), provided, however, that in no
event shall any effect that results from (a) the public announcement or pendency
of the transactions contemplated hereby or any actions taken in compliance with
this Agreement, (b) changes affecting the pharmaceuticals industry generally
unless such changes adversely affect the Company or its Subsidiaries (assuming
the consummation of the Distribution) in a materially disproportionate manner,
(c) changes affecting the United States economy generally, (d) changes in the
trading price of the Company Common Stock, or (e) stockholders class action
litigation arising from allegations of a breach of fiduciary duty relating to
this Agreement, the transactions contemplated hereby or any actions taken in
compliance with this Agreement , constitute a Company Material Adverse Effect.
The Company has heretofore made available to Parent true and complete copies of
the Certificate of Incorporation and the by-laws of the Company as currently in
effect.

     Section 3.2  Corporate Authorization.
                  -----------------------

       (a)   The Company has the requisite corporate power and authority
toexecute and deliver this Agreement and, subject to approval of the Company's
stockholders, as set forth in Section 3.2(b) hereof and as contemplated by
Section 5.3 hereof, to perform its obligations hereunder. The execution and
delivery of this Agreement and the performance of its obligations hereunder have
been duly and validly authorized, and this Agreement and the Voting Agreement
have been approved, by the Board of Directors of the Company and no other
corporate proceedings on the part of the Company, other than the approval and
adoption of this Agreement by the

                                      -11-
<PAGE>

Company's stockholders, are necessary to authorize the execution, delivery and
performance of this Agreement. This Agreement has been duly executed and
delivered by the Company and constitutes, assuming due authorization, execution
and delivery of this Agreement by Parent, a valid and binding obligation of the
Company, enforceable against the Company in accordance with its terms.

          (b)     Under applicable law, the Certificate of Incorporation and the
rules of the NASDAQ, the affirmative vote of the holders of a majority of the
shares of Common Stock and Class A Common Stock, voting together as a single
class, and the consent of the holders of a majority of the outstanding shares of
Class A Common Stock, voting as a separate class, outstanding on the record date
established by the Board of Directors of the Company in accordance with the by-
laws of the Company, applicable law and this Agreement, are the only votes
required to adopt this Agreement and, if applicable, approve the Distribution.

     Section 3.3  Consents and Approvals; No Violations.
                  -------------------------------------

             (a)  Neither the execution and delivery of this Agreement nor the
performance by the Company of its obligations hereunder will (i) conflict with
or result in any breach of any provision of the Certificate of Incorporation or
the by-laws of the Company; (ii) result in a violation or breach of, or
constitute (with or without due notice or lapse of time or both) a default (or
give rise to any right of termination, cancellation or acceleration or
obligation to repurchase, repay, redeem or acquire or any similar right or
obligation) under any of the terms, conditions or provisions of any note,
mortgage, letter of credit, other evidence of indebtedness, guarantee, license,
permit, lease or agreement or similar instrument or obligation to which the
Company or any of its Subsidiaries is a party or by which any of them or any of
their assets may be bound or (iii) assuming that the filings, registrations,
notifications, authorizations, consents and approvals referred to in subsection
(b) below have been obtained or made, as the case may be, violate any order,
injunction, decree, statute, rule or regulation of any Governmental Entity to
which the Company or any of its Subsidiaries is subject, excluding from the
foregoing clauses (ii) and (iii) such requirements, defaults, breaches, rights
or violations that would not, in the aggregate, reasonably be expected to have a
Company Material Adverse Effect and/or would not have a material adverse effect
on the ability of the Company to perform its obligations hereunder.

             (b)  No filing or registration with, notification to, or
authorization, consent or approval of, any government or any agency, court,
tribunal, commission, board, bureau, department, political subdivision or other
instrumentality of any government (including any regulatory or administrative
agency), whether federal, state, multinational (including, but not limited to,
the European Community), provincial, municipal, domestic or foreign (each, a
"Governmental Entity") is required in connection with the execution and delivery
of this Agreement by the Company or the performance by the Company of its
obligations hereunder, except (i) the filing of the Certificate of Merger in
accordance with the DGCL; (ii) compliance with any applicable requirements of
the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the
rules and regulations thereunder (the "HSR Act") or any foreign laws regulating
competition, antitrust, investment or exchange controls; (iii) compliance with
any applicable requirements of the Securities Exchange Act of 1934, as amended,
and the rules and regulations thereunder (the "Exchange Act") and of the
Securities Act of 1933, as amended, and the rules and regulations thereunder
(the "Securities Act"); (iv) compliance with any applicable requirements of
state blue sky or takeover laws and (v) such

                                      -12-
<PAGE>

other consents, approvals, orders, authorizations, notifications, registrations,
declarations and filings the failure of which to be obtained or made would not,
in the aggregate, reasonably be expected to have a Company Material Adverse
Effect and/or would not have a material adverse effect on the ability of the
Company to perform its obligations hereunder.

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

agreement or arrangement, in each case, that is in writing and sponsored,

Affiliate"), that together with the Company would be deemed a "single employer"
within the meaning of section 4001(b) of ERISA, or to which the Company or an
ERISA Affiliate is party, whether written or oral, for the benefit of any
employee, consultant, director or former employee, consultant or director of the
Company or any Subsidiary of the Company. The plans, funds, programs, agreements
and arrangements listed on Schedule 3.12(a) of the Company Disclosure Schedule
are referred to herein collectively as the "Plans".

            (b)    With respect to each Plan, the Company has heretofore
delivered or made available to Parent true and complete copies of the Plan and
any amendments thereto (or if the Plan is not a written Plan, a description
thereof), any related trust or other funding vehicle, the most recent reports or
summaries required under ERISA or the Code and the most recent determination
letter received from the Internal Revenue Service with respect to each Plan
intended to qualify under section 401 of the Code.

            (c)    No liability under Title IV or section 302 of ERISA has been
incurred by the Company or any ERISA Affiliate that has not been satisfied in
full, other than liability for premiums due the Pension Benefit Guaranty
Corporation (which premiums have been paid when due).

            (d)    Each Plan has been operated and administered in all material
respects in accordance with its terms and applicable law, including, but not
limited to, ERISA and the Code.

            (e)    Each Plan intended to be "qualified" within the meaning of
section 401(a) of the Code has received a favorable determination letter from
the Internal Revenue Service, or in the case of such a Plan for which a
favorable determination letter has not yet been received, the applicable
remedial amendment period under Section 401(b) of the Code has not expired.

            (f)    Except as set forth on Schedule 3.12(f) of the Company
Disclosure Letter, no Plan provides medical, surgical or hospitalization
benefits (whether or not insured) for employees or former employees of the
Company or any Subsidiary for periods extending beyond their retirement or other
termination of service, other than (i) coverage mandated by applicable law, or
(ii) benefits

                                      -18-
<PAGE>

the full cost of which is borne by the current or former employee (or his or her
beneficiary), dependant or other covered person.

          (g)  There are no pending, or to the knowledge of the Company,
threatened or anticipated, claims that would reasonably be expected, in the
aggregate, to have a Company Material Adverse Effect by or on behalf of any
Plan, by any employee or beneficiary covered under any such Plan, or otherwise
involving any such Plan (other than routine claims for benefits).

          (h)  Except as set forth on Schedule 3.12(h) of the Company Disclosure
Letter, the consummation of the transactions contemplated by this Agreement will
not, either alone or in combination with another event, (i) entitle any current
or former employee or officer of the Company or any ERISA Affiliate to severance
pay, unemployment compensation or any other payment, except as expressly
provided in this Agreement, or (ii) accelerate the time of payment or vesting
(other than as a result of a full or partial plan termination resulting from the
transactions contemplated by this Agreement), or increase the amount of
compensation due any such employee or officer, other than payments,
accelerations or increases (x) under any employee benefit plan that is subject
to the laws of a jurisdiction outside of the United States or (y) mandated by
applicable law.

          (i)  To the knowledge of the Company, all employee benefit plans that
are subject to the laws of any jurisdiction outside the United States are in
material compliance with such applicable laws, including relevant Tax laws, and
the requirements of any trust deed under which they were established, except for
such exceptions to the foregoing which, in the aggregate, would not reasonably
be expected to have a Company Material Adverse Effect. Schedule 3.12(k) lists
all material employee pension benefit plans that are subject to the laws of any
jurisdiction outside the United States except for such plans that are
governmental or statutory plans.

          (j)  Each Plan can be amended prospectively or terminated at any time,
without advance notice, and without any liability other than for benefits
accrued prior to such amendment or termination (other than administrative
charges normally incurred in a plan termination).

          (k)  No agreement, commitment, or obligation exists to increase any
benefits under any Plan or to adopt any new Plan, other than in the ordinary
course of business.

          (l)  No Plan has any unfunded accrued benefits that are not fully
reflected in the Financial Statements in accordance with the Company's ordinary
accounting procedures.

          (m)  No pension plan subject to Title IV of ERISA (an "ERISA Pension
Plan") has incurred any "accumulated funding deficiency" or "waived funding
deficiency" within the meaning of Section 302 of ERISA or Section 412 of the
Code and the Company has never sought to obtain any variance from the minimum
funding standards pursuant to Section 412(d) of the Code. The funding method
used in connection with each ERISA Pension Plan meets the requirements of ERISA
and the Code and the actuarial assumptions used in connection with each such
plan are reasonable, given the experience of such ERISA Pension Plan and
reasonable expectations.

          (n)  The fair market value of the plan assets of each ERISA Pension
Plan are at least equal to (i) the present value of its benefit liabilities (as
defined in ERISA Section 4001(a)(16),

                                      -19-
<PAGE>

including any unpredictable contingent event benefits within the meaning of Code
Section 412(l)(7), and determined on the basis of assumptions prescribed by the
PBGC for purposes of ERISA Section 4044), and (ii) the Projected Benefit
Obligations thereunder, as defined in Statement of Financial Accounting
Standards No. 87, including any allowance for indexation and ad hoc increases.
                                                             -- ---
No ERISA Pension Plan has been completely or partially terminated or been the
subject of a Reportable Event under ERISA Section 4043. No proceeding by the
PBGC to terminate any ERISA Pension Plan has been instituted, and the Company
has not incurred any liability to the PBGC (other than the PBGC premiums, all of
which have been timely paid) or otherwise under Title IV of ERISA with respect
to any ERISA Pension Plan.

            (o)   Neither the Company nor any Subsidiary maintains or
participates in any Voluntary Employees' Beneficiary Association, under Code
Sections 419 and 419A, which is intended to be exempt from taxation under
section 501(c)(9) of the Code.

            (p)   Neither the Company nor any ERISA Affiliate maintains,
participates in, contributes to, or has any obligation to contribute or any
liability with respect to any multiple employer or multiemployer plan, or has
had any obligation with respect to such a plan during the six years immediately
preceding the date of this Agreement.

"Permits") required to conduct the business of the Company and the Non-Energy
Subsidiaries have been obtained, are in full force and effect and are being
complied with except for such violations and failures to have Permits in full

liability for any Environmental Claim the Company or any Non-Energy Subsidiary
has or may have retained or assumed either contractually or by operation of law;

good standing in each jurisdiction where the character of the property owned,
leased or operated by it or the nature of its activities makes such
qualification necessary, except for those jurisdictions where failures to be so

Effect" means a material adverse effect on the ability of Parent and Merger Sub

Sub, and no other proceedings on the part of Parent (or its stockholders) or
Merger Sub are necessary to authorize the execution, delivery and performance of

Parent and Merger Sub, enforceable against them in accordance with its terms.

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

             (a)  Neither the execution and delivery of this Agreement nor the
performance by Parent or Merger Sub of their obligations hereunder will (i)
conflict with or result in any breach of any provision of the certificate of
incorporation or by-laws (or other governing or organizational documents) of
Parent or Merger Sub, or (ii) result in a violation or breach of, or constitute
(with or without due notice or lapse of time or both) a default (or give rise to
any right of termination, cancellation or acceleration or obligation to
repurchase, repay, redeem or acquire or any similar right or obligation) under
any of the terms, conditions or provisions of any note, mortgage, letter of
credit, other evidence of indebtedness, guarantee, license, lease or agreement
or similar instrument or obligation to which Parent or Merger Sub is a party or
by which any of them or any of the respective assets used or held for use by any

any order, injunction, decree, statute, rule or regulation of any Governmental
Entity to which Parent or Merger Sub is subject, excluding from the foregoing
clauses (ii) and (iii) such requirements, defaults, breaches, rights or
violations that would not, in the aggregate, reasonably be expected to have a
Parent Material Adverse Effect.

authorization, consent or approval of, any Governmental Entity is required in
connection with the execution and delivery of this Agreement by Parent or Merger
Sub or the performance by them of their obligations hereunder, except (i) the
filing of the Certificate of Merger in accordance with the DGCL; (ii) compliance
with any applicable requirements of the HSR Act or any non-U.S. laws regulating
competition, antitrust, investment or exchange controls; (iii) compliance with
any applicable requirements of the Exchange Act; (iv) compliance with any
applicable requirements of state blue sky or takeover laws and (v) such other
consents, approvals, orders, authorizations, notifications, registrations,
declarations and filings the failure of which to be obtained or made would not
reasonably be expected to have a Parent Material Adverse Effect.

     Section 4.4  Proxy Statement.
                  ---------------

     None of the information provided by Parent or Merger Sub to the Company in
writing for inclusion in the Proxy Statement will at the time of the mailing of
the Proxy Statement to the stockholders of the Company and at the time of the
Special Meeting, contain any untrue statement of a material fact or omit to

applicable laws, ordinances, rules and regulations of any federal, state, local

                                                --------
Directors of the Company may withdraw, modify or change such recommendation if
(i) it believes in good faith that a Superior Proposal (as defined in Section

with the Company's outside counsel, that the withdrawal, modification or change
of such recommendation is necessary to comply with the fiduciary duties of the
Board of Directors of the Company under applicable law.

             (b)  Promptly following the date of this Agreement, the Company
shall prepare and file with the SEC a proxy statement relating to the Company
Approval Matters (together with any amendments thereof and any supplements
thereto, the "Proxy Statement"). Promptly following the date of this Agreement,
the Company shall also prepare and file with the SEC the Distribution Statement.
Parent and the Company shall cooperate with each other in connection with the
preparation of the foregoing documents. The Company will use commercially
reasonable efforts to cause the Proxy Statement and the Distribution Statement

Distribution Statement is declared effective by the SEC.

             (c)  The Company shall as promptly as practicable notify (and
provide copies to) Parent of the receipt of any comments from the SEC relating
to the Proxy Statement and the Distribution Statement. All filings by the
Company with the SEC in connection with the transactions contemplated hereby,

stockholders in connection with the transactions contemplated by this Agreement
shall be subject to the prior review of Parent.

<PAGE>

bly request and (iii) instruct the Company's and its Non-Energy Subsidiaries'
employees, counsel and financial advisors to cooperate with Parent in its
investigation of the business of the Company and its Subsidiaries; provided that
any information and documents received by Parent or its Representatives (whether
furnished before or after the date of this Agreement) shall be held in
accordance with the Confidentiality Agreement dated April 27, 2000 between Dutch
Parent and the Company (the "Confidentiality Agreement"), which shall remain in
full force and effect pursuant to the terms thereof, notwithstanding the
execution and delivery of this Agreement or the termination hereof until the
Effective Time.

     Section 5.5  No Solicitation.  From the date hereof until the Effective
                  ---------------
Time or, if earlier, the termination of this Agreement, the Company and its
Subsidiaries shall not (whether directly or indirectly through advisors, agents
or other intermediaries), and the Company shall cause its and its Subsidiaries'
respective officers, directors, advisors, representatives or other agents not
to, directly or indirectly, (a) solicit, initiate or encourage any Acquisition
Proposal (as defined hereafter), (b) engage in negotiations with, or disclose

access to the properties, books or records of the Company or its Subsidiaries
to, any person or group (other than Parent or any designees of Parent)
concerning any Acquisition Proposal or (c) enter into any agreement with respect
to any Acquisition Proposal, other than in the manner contemplated by Section
7.1(f) provided, however, that if the Board of Directors of the Company
determines in good faith, based on such matters as it deems relevant, acting
only after consultation with the Company's outside counsel that it is necessary
to comply with its fiduciary duties to the Company's stockholders under the
DGCL, the Company may, in response to a bona fide Acquisition Proposal that was
not solicited or encouraged in breach of this Section 5.5 and that the Board of
Directors of the Company determines in good faith, after consultation with the
Company's financial advisor, constitutes a Superior Proposal, (i) furnish
information to the person or group who made such Acquisition Proposal, but only
pursuant to a confidentiality agreement substantially in the same form as was
executed by Parent prior to the execution of this Agreement and only if copies
of such information (to the extent not previously supplied) are concurrently
provided to Parent, and (ii) participate in discussions and negotiations
regarding such proposal or offer. The Company shall promptly (and in any event
within one business day after any of the Company's officers and directors
becoming aware thereof) (i) notify Parent in the event the Company or any of its
Subsidiaries or other affiliates or any of their respective officers, directors,
employees and agents receives any Acquisition Proposal, including the material
terms and conditions thereof and the identity of the party submitting such
proposal, and any request for non-public information in connection with an
Acquisition Proposal, (ii) provide a copy of any written agreements, proposals
or other materials that the Company receives from any such person or group, and
(iii) notify Parent of any material changes or developments with respect to any
of the matters described in clauses (i) and (ii). The Company shall immediately
cease and cause to be terminated any activities, discussions or negotiations
commenced or conducted prior to the date of this Agreement with any party other
than Parent or its affiliates with respect to any Acquisition Proposal. For
purposes of this Agreement, "Acquisition Proposal" means any offer or proposal
for a merger, consolidation, recapitalization, liquidation or other business
combination involving the Company or the acquisition or purchase of over 50% or
more of any class of equity securities of the Company, or any tender offer
(including self-tenders) or exchange offer that if consummated would result in
any person beneficially owning 50% or more of any class of equity securities of
the Company, or a substantial portion of the assets of, the Company and its
Subsidiaries taken as a whole, other than the

                                      -32-
<PAGE>

transactions contemplated by this Agreement (including the Distribution). As
used herein, a "Superior Proposal" shall mean a bona fide Acquisition Proposal
which in the good faith judgment of the Company's Board of Directors, based on
such matters as it deems relevant, after consultation with the Company's
financial advisor, (i) provides greater benefits to the Company's stockholders
than those provided pursuant to this Agreement and (ii) provides that any
financing required to consummate the transaction contemplated by the offer is
committed and in the good faith determination of the Board of Directors of the
Company, after consultation with the Company's financial advisor, is likely to
be obtained by such person on a timely basis. Nothing contained in this Section
5.5 shall prohibit the Company or the Company's Board of Directors from taking
and disclosing to the Company's stockholders a position with respect to a tender
or exchange offer by a third party pursuant to Rules 14d-9 and 14e-2(a)
promulgated under the Exchange Act or from making any disclosure required by
applicable law.

     Section 5.6  Director and Officer Liability.
                  ------------------------------

             (a)  Parent shall cause all rights to indemnification and all
limitations on liability existing in favor of any individuals who on or prior to
the Effective Time were officers, directors, employees or agents of the Company
and any of its Non-Energy Subsidiaries (the "Indemnitees") as provided in the
Certificate of Incorporation or by-laws of the Company or an agreement between
an Indemnitee and the Company or a Subsidiary of the Company as in effect as of
the date hereof to continue in full force and effect in accordance with its
terms and to be satisfied by the Surviving Corporation or Parent.

             (b)  Subject to the terms and conditions set forth on Schedule
1.5(a), for six years after the Effective Time, Parent shall cause the Surviving
Corporation to provide officers' and directors' liability insurance in respect
of acts or omissions occurring prior to the Effective Time covering each such
person currently covered by the Company's officers' and directors' liability
insurance policy on terms with respect to coverage and amount no less favorable
than those of such policy in effect on the date hereof; provided, however, that
                                                        --------  -------
in no event shall the Surviving Corporation be required to expend more than an
amount per year equal to 150% of current annual premiums paid by the Company for
such insurance (the "Maximum Amount") to maintain or procure insurance coverage
pursuant hereto; provided, further, that if the amount of the annual premiums
                 --------  -------
necessary to maintain or procure such insurance coverage exceeds the Maximum
Amount, the Surviving Corporation shall maintain or procure, for such six-year
period, the most advantageous policies of directors' and officers' insurance
obtainable for an annual premium equal to the Maximum Amount.  The Company
represents that the current annual premium for such insurance equals
approximately $165,000.

             (c)  The obligations of Parent and the Surviving Corporation under
this Section 5.6 shall not be terminated or modified in such a manner as to
adversely affect any Indemnitee to whom this Section 5.6 applies without the
consent of such affected Indemnitee (it being expressly agreed that the
Indemnitees to whom this Section 5.6 applies shall be third party beneficiaries
of this Section 5.6).

     Section 5.7  Commercially Reasonable Efforts.  Upon the terms and subject
                  -------------------------------

connection with the preparation of the Proxy Statement, (ii) in determining
whether any action by or in respect of, or filing with, any Governmental Entity
is required, or any actions, consents, approvals or waivers are required to be
obtained from parties to any material contracts, in connection with the
consummation of the transactions contemplated by this Agreement and (iii) in
seeking any such actions, consents, approvals or waivers or making any such
filings, furnishing information required in connection therewith or with the
Proxy Statement or Distribution Statement and seeking timely to obtain any such
actions, consents, approvals or waivers. Without limiting the provisions of this
Section 5.8, each party hereto shall file with the Department of Justice and the
Federal Trade Commission a Pre-Merger Notification and Report Form pursuant to
the HSR Act in respect of the transactions contemplated hereby as soon as
reasonably practicable, and each party will use commercially reasonable efforts
to take or cause to be taken all actions necessary, including to promptly and
fully comply with any requests for information from regulatory Governmental
Entities, to obtain any clearance, waiver, approval or authorization relating to
the HSR Act that is necessary to enable the parties to consummate the
transactions contemplated by this Agreement. Without limiting the provisions of
this Section 5.8, each party hereto shall use commercially reasonable efforts to
promptly make the filings required to be made by it with all foreign
Governmental Entities in any jurisdiction in which the parties believe it is
necessary or advisable.

             (b)  The Company and Parent shall each use commercially reasonable
efforts to resolve such objections, if any, as may be asserted with respect to
the Merger or any other transaction contemplated by this Agreement under any
Antitrust Law (as defined below). If any administrative, judicial or legislative
action or proceeding is instituted (or threatened to be instituted) challenging
the Merger or any other transaction contemplated by this Agreement as violative
of any Antitrust Law, the Company and Parent shall each cooperate to contest and
resist any such action or proceeding, and to have vacated, lifted, reversed or
overturned any decree, judgment, injunction or other order (whether temporary,
preliminary or permanent) that is in effect and that restricts, prevents or
prohibits consummation of the Merger or any other transaction contemplated by
this Agreement, including, without limitation, by pursuing all reasonable
avenues of administrative and judicial appeal. Notwithstanding anything to the
contrary in this Agreement, none of Parent, any of its Subsidiaries or the
Surviving Corporation, shall be required (and the Company shall not, without the
prior written consent of Parent, agree, but shall, if so directed by Parent,
agree) to hold separate or divest any of their respective assets or operations
or enter into any consent decree or licensing or other arrangement with respect
to any of their assets or operations.

             (c)  Each of the Company and Parent shall promptly inform the other
party of any material communication received by such party from the Federal
Trade Commission, the Antitrust Division of the Department of Justice or any
other governmental or regulatory authority regarding any of the transactions
contemplated hereby.

Clayton Act, as amended, and all other federal, state and foreign statutes,
rules, regulations, orders, decrees, administrative and judicial doctrines, and
other laws that are designed or intended to prohibit, restrict or regulate

year thereafter, the Parent, in its sole discretion, shall either: (i) continue

similar terms in the aggregate as in effect immediately prior to the Effective
Time, or (ii) arrange for each participant in the Plans employed at the Company
or a Non-Energy Subsidiary ("Company Participants") to participate in any
similar plans of the Parent ("Parent Plans") on terms in the aggregate no less
favorable than those offered to similarly situated employees of Parent, or (iii)
a combination of clauses (i) and (ii). Each Company Participant who continues to
be employed by the Company or any of its subsidiaries immediately following the
Effective Time shall, to the extent permitted by law and applicable tax
qualification requirements, and subject to any generally applicable break in
service or similar rule, receive credit for purposes of eligibility to

Company or its subsidiaries prior to the Effective Time. Parent shall cause any
and all pre-existing condition limitations, eligibility waiting periods and
evidence of insurability requirements under any group health plans to be waived
with respect to such Company Participants and their eligible dependents and
shall provide them with credit for any co-payments and deductibles prior to the
Effective Time for purposes of satisfying any applicable deductible, out-of-
pocket, or similar requirements under any Parent Plans in which they are
eligible to participate immediately after the Effective Time. The provisions of
this Section 5.11 shall not create in any employee or former employee of the
Company or any Subsidiary of the Company any rights to employment or continued
employment with Parent, the Surviving Corporation or any Subsidiary or affiliate
thereof or infringe upon the right of any such entity to terminate the
employment of any such employee for any reason or no reason.

other employees under the Company's general severance plans.

                  ------------------------------------------
otherwise provided herein or in any document contemplated hereby, the
representations and warranties contained herein and in any certificate or other
writing delivered pursuant hereto shall not survive the Effective Time. All
other covenants and agreements contained herein which by their terms are to be
performed in whole or in part, or which prohibit actions, subsequent to the
Effective Time, shall survive the Merger in accordance with their terms.

     Section 8.3  Interpretation.  References herein to the "knowledge" (and all
                  --------------
variants and derivatives thereof) of a party shall mean the actual knowledge,
after reasonable inquiry, of the executive officers of such party. Whenever the

                                      -42-
<PAGE>

in this Agreement, the term "affiliate" shall have the meaning set forth in Rule
12b-2 promulgated under the Exchange Act.

     The article and section headings contained in this Agreement are solely for
the purpose of reference, are not part of the agreement of the parties hereto
and shall not in any way affect the meaning or interpretation of this Agreement.
Any matter disclosed pursuant to any Schedule of the Company Disclosure Schedule
or the Parent Disclosure Schedule shall not be deemed to be an admission or
representation as to the materiality of the item so disclosed.

     Section 8.4  Amendments, Modification and Waiver.  (a) Except as may
                  -----------------------------------
otherwise be provided herein, any provision of this Agreement may be amended,
modified or waived by the parties hereto, by action taken by or authorized by
their respective Board of Directors, prior to the Closing Date if, and only if,
such amendment or waiver is in writing and signed, in the case of an amendment,
by the Company and Parent or, in the case of a waiver, by the party against whom
the waiver is to be effective; provided that after the adoption of this
Agreement by the stockholders of the Company, no such amendment shall be made
except as allowed under applicable law.

             (b)  No failure or delay by any party in exercising any right,
power or privilege hereunder shall operate as a waiver thereof nor shall any

remedies provided by law.

     Section 8.5  Successors and Assigns.  The provisions of this Agreement
                  ----------------------

respective successors and assigns; provided that neither the Company nor Parent
may assign, delegate or otherwise transfer any of its rights or obligations
under this Agreement without the consent of the other party hereto.

     Section 8.6  Expenses.  Except as provided in Sections 1.2(b) and 7.3,

Agreement and the consummation of the transactions contemplated hereby.

     Section 8.7  Specific Performance.  The parties acknowledge and agree that
                  --------------------
any breach of the terms of this Agreement would give rise to irreparable harm
for which money damages would not be an adequate remedy and accordingly the
parties agree that, in addition to any other remedies, each shall be entitled to
enforce the terms of this Agreement by a decree of specific performance without
the necessity of proving the inadequacy of money damages as a remedy.

     Section 8.8  Governing Law.  This Agreement shall be governed by and
                  -------------
construed in accordance with the laws of the State of Delaware (regardless of
the laws that might otherwise govern under applicable principles of conflicts of
laws thereof) as to all matters, including, but not limited to, matters of
validity, construction, effect, performance and remedies.

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

jurisdiction of the courts of the State of Delaware and the United States
District Court of the District of Delaware and waive any objections or rights as

                   ------------
Agreement is invalid, illegal or incapable of being enforced by any rule of law,
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated herein are not affected in any manner
materially adverse to any party hereto. Upon such determination that any term or
other provision is invalid, illegal or incapable of being enforced, the parties
hereto shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the parties as closely as possible in a mutually
acceptable manner.

     Section 8.11  Third Party Beneficiaries.  This Agreement is solely for the
                   -------------------------
benefit of the Company and its successors and permitted assigns, with respect to
the obligations of Parent under this Agreement, and for the benefit of Parent
and its successors and permitted assigns, with respect to the obligations of the
Company under this Agreement, and this Agreement shall not, except to the extent
necessary to enforce the provisions of Article I and Section 5.6 hereof be
deemed to confer upon or give to any other third party any remedy, claim,
liability, reimbursement, cause of action or other right.

     Section 8.12  Entire Agreement.  This Agreement, including any exhibits or
                   ----------------

hereto shall have received counterparts hereof signed by all of the other
