officers and directors and is qualified in its entirety by reference to the
Merger
 
                                       2
<PAGE>
Agreement. For the purposes of this Item 3(b), capitalized terms used and not
otherwise defined herein have the meanings given to such terms in the Merger
Agreement.
 
THE OFFER
 
    The Merger Agreement requires that no later than two business days after the
public announcement of the terms of this Agreement, (i) Parent and Purchaser
file Purchaser's Tender Offer Statement on Schedule 14D-1 with the Commission
and commence the Offer in accordance with the requirements of Regulations 14D
and 14E promulgated under the Exchange Act and (ii) the Company file with the
Commission the Company's Solicitation/Recommendation Statement on Schedule 14D-9
with respect to the Offer, which will be mailed to the holders of Shares and
contains the recommendation of the Company's Board of Directors that holders of
Shares accept the Offer. Parent, Purchaser and the Company have each agreed to
use its reasonable best efforts to cause all the Offer Conditions to be
fulfilled and to avoid the occurrence of any event or to cure any event that may
prevent the Offer Conditions from being fulfilled.
 
    The obligation of Purchaser to accept for payment and pay for any Shares
tendered pursuant to the Offer is subject only to the conditions to the Offer
set forth in Section 13 (the "OFFER CONDITIONS"). Without the prior written
consent of the Company, Purchaser may not decrease the Offer Price or change the
form of consideration payable in the Offer, decrease the number of Shares
Purchaser seeks to purchase in the Offer, change the Offer Conditions, impose
additional conditions to the Offer, or amend any other term of the Offer in any
manner adverse to the holders of Shares. Purchaser may waive any condition to
the Offer other than the Minimum Condition without the consent of the Company.
Subject to the satisfaction of all the Offer Conditions as of any Expiration
Date, Purchaser will accept for payment and pay for all Shares validly tendered
and not withdrawn pursuant to the Offer as soon as practicable after such
Expiration Date. Parent must make reasonable provision for payment of the Offer
proceeds to be made by wire transfer of immediately available funds to any
person tendering Shares representing more than 1% of the outstanding Shares.
 
BOARD REPRESENTATION
 
    Promptly upon the purchase by Purchaser of Shares pursuant to the Offer and
from time to time thereafter, Purchaser will be entitled to designate at least a
number of directors on the Company's Board of Directors equal to the product of
(i) the total number of directors on the Company's Board of Directors and (ii)
Purchaser's percentage ownership of the outstanding Shares of the Company. The
Company will either increase the size of the Company's Board of Directors or
secure the resignation of the necessary number of directors to enable
Purchaser's designees to be elected to the Company's Board of Directors, and
will cause such designees to be elected to the Company's Board of Directors.
 
COMPANY STOCK OPTIONS
 
    The Merger Agreement provides that promptly after the commencement of the
Offer, the Company must offer to cancel any and all of the outstanding options
to purchase Shares and each outstanding stock appreciation right (each such
option to purchase one share and each such unit representing one share being
referred to as an "OPTION") granted under the Company's Incentive Stock Option
Plan and the Company's Stock Appreciation Rights Plan (together, the "OPTION
PLAN") for cash consideration as follows. Each holder of a vested Option (after
giving consideration to any acceleration of vesting provided in the Option Plan
or the Company's Special Bonus and Severance Plan (the "SBS PLAN")) will be
offered the right to have 100% of his or her Options canceled by the Company in
consideration of a payment by the Company for each Option in an amount equal to
the excess of the Offer Price over the applicable exercise price of such Option
(the "OPTION CONSIDERATION"). Cancellation of and payment of the consideration
for the Options will be conditioned upon the purchase of Shares by the Purchaser
pursuant to the Offer. If the Purchaser purchases Shares pursuant to the Offer,
the Options will be
 
                                       3
<PAGE>
canceled and the consideration therefor will be paid as promptly as possible
following the purchase of Shares by the Purchaser upon expiration of the Offer.
 
    The Merger Agreement also provides that at the Effective Time, each then
outstanding Option will be converted automatically into the right to receive the
Option Consideration, but only to the extent then vested and exercisable, taking
into account any acceleration of vesting provided for in the Option Plan or the
SBS Plan. The Option Consideration will be paid upon delivery of any then
outstanding Options by or on behalf of the Option holder.
 
THE MERGER
 
    The Merger Agreement provides that at the Effective Time (as defined below)
and upon the terms and subject to the conditions of the Merger Agreement and
Delaware law, Purchaser will merge with and into the Company, the separate
corporate existence of Purchaser will cease, and the Company will continue as
the surviving corporation, succeeding to and assuming all the rights and
obligations of Purchaser in accordance with Delaware law.
 
    As soon as practicable after the satisfaction or waiver of the conditions to
the Merger, the parties will file a certificate of ownership and merger with the
Secretary of State of the State of Delaware and will make all other filings or
recordings required under Delaware law. The Merger will become effective upon
the filing of the certificate of ownership and merger or such later time
specified in such certificate (the "EFFECTIVE TIME").
 
    At the Effective Time, (i) each Share not purchased by Purchaser in the
Offer (other than Shares held by stockholders who properly exercise appraisal
rights under Delaware law and Shares owned by the Company or one of its
subsidiaries or by Parent or Purchaser or one of its subsidiaries) will be
converted by operation of law into the right to receive the Merger Consideration
in cash, payable to the holder, without interest, upon surrender of the
certificate formerly representing such Common Share, (ii) each Share owned by
the Company or one of its subsidiaries or by Parent or Purchaser or one of its
subsidiaries will be canceled without payment, and (iii) each share of the
common stock of the Purchaser outstanding immediately before the Effective Time
will be converted into one share of common stock of the Company, as the
surviving corporation of the Merger.
 
    Shares outstanding immediately prior to the Effective Time and held by a
holder who has not voted in favor of the Merger or consented thereto in writing
will have the right to demand appraisal for such Shares in accordance with
Delaware law unless such holder fails to perfect or withdraws or otherwise loses
his or her right to appraisal and payment under Delaware law. If, after the
Effective Time, any such holder fails to perfect or withdraws or loses his right
to appraisal, the holder's Shares will be treated as if they had been converted
as of the Effective Time into the right to receive the Merger Consideration
without interest.
 
    Promptly after the Effective Time, the surviving corporation will mail each
record holder as of the Effective Time a letter of transmittal and instructions
for effecting the surrender of certificates that represented Shares prior to the
Effective Time for the Merger Consideration. Upon surrender of the
certificate(s) representing a holder's Shares, together with a completed and
validly executed letter of transmittal, such holder will be entitled to receive
the Merger Consideration in respect thereof. Until so surrendered or exchanged,
each certificate will represent only the right to receive the Merger
Consideration.

any confidentiality, standstill or other similar agreement to which the Company
or any of its subsidiaries is a party; or (xii) agree to take any action which
would violate the foregoing covenants.
 
    ACCESS TO INFORMATION.  The Company will give Parent and Purchaser and their
representatives reasonable access to all necessary information. Parent and
Purchaser have agreed to be bound by a Confidentiality Agreement dated March 6,
1998.
 
    REASONABLE EFFORTS; NOTICE OF CERTAIN DEVELOPMENTS.  Each of the parties
will use its reasonable efforts to take all actions and do all things necessary,
proper or advisable to consummate and make effective the transactions
contemplated by the Offer and the Merger Agreement. Each of the parties will
promptly inform the other party of any event or circumstance that is discovered
at any time before the Effective Time that should be set forth in an amendment
to the Schedule 14D-1 or Schedule 14D-9.
 
    PUBLIC ANNOUNCEMENTS.  Parent and Purchaser, on the one hand, and the
Company, on the other hand, will consult with each other before issuing any
press release or otherwise making any public statements with respect to the
transactions contemplated by the Merger Agreement except as required by
applicable law or by any rule or regulation of the NYSE.
 
    INDEMNIFICATION.  For a period not less than six years from the Effective
Time, (i) all existing rights of directors and officers to indemnification as
provided in the respective charters or by-laws of the Company and its
subsidiaries or in an agreement with the Company will remain in full force, and
(ii) in accordance with such rights, Parent will indemnify and hold harmless the
directors and officers of the Company and its subsidiaries from and against any
action, proceeding or investigation arising out of
 
                                       6
<PAGE>
events occurring prior to, and including, the Effective Time and will pay all
reasonable expenses (including legal and the cost of any investigation and
preparation) incurred in connection therewith.
 
    Parent will cause the Company to maintain in effect for six years after the
Effective Time, for the benefit of all current and former directors and officers
of the Company the coverage provided by the current directors' and officers'
liability insurance policies maintained by the Company; provided, however, that
(i) the Company will not be required to incur any annual premium in excess of
300% of the last annual premium paid prior to the date of the Merger Agreement
for all current directors' and officers' liability insurance policies maintained
by the Company and if the Company is unable to obtain the required insurance it
shall obtain as much comparable insurance as possible for an annual premium
equal to this maximum amount and (ii) the Company may substitute policies that
are not less advantageous.
 
    NOTIFICATION OF CERTAIN MATTERS.  The Company will give prompt notice to
Parent, and Parent will give prompt notice to the Company, as the case may be,
of (i) the occurrence or non-occurrence of any event which would be reasonably
likely to demonstrate that any representation or warranty contained in the
Merger Agreement was or is untrue or inaccurate or reasonably likely to cause
any material covenant, condition or agreement not to be satisfied in all
material respects and (ii) any failure of the Company, Parent or Purchaser, as
the case may be, to comply with or satisfy any covenant, condition or agreement
under the Merger Agreement in any material respect.
 
    NO SOLICITATION.  The Merger Agreement requires the Company immediately to
cease any existing activities, discussions and negotiations with any third
parties with respect to any inquiry, proposal or offer for any recapitalization,
merger, consolidation or other business combination involving the Company, or
acquisition of any capital stock (other than upon exercise of the Options which
are outstanding as of the date of the Merger Agreement) or any portion of the
assets (except for certain specified assets and acquisitions of assets in the
ordinary course of business consistent with past practice) of the Company and
its subsidiaries, or any combination of the foregoing (a "COMPETING
TRANSACTION"). The Company will not, directly or indirectly, through any
officer, director, employee, representative or agent or any of its subsidiaries,
(i) solicit, initiate, encourage, facilitate, furnish or disclose non-public
information in furtherance of a Competing Transaction or negotiate with any
person for the purpose of facilitating any Competing Transaction provided that
prior to the purchase of the Shares by the Purchaser pursuant to the Offer, the
Company may furnish information to, and negotiate or otherwise engage in
discussions with, any party who makes a bona fide proposal regarding a Competing
Transaction which was not solicited by the Company after the date of the Merger
Agreement and which does not violate any standstill agreement if the Board of
Directors after consultation with its counsel determines in good faith that
failing to consider and cooperate with such other party regarding such Competing
Transaction would constitute a breach of the fiduciary duties of the Board to
the Company's stockholders under applicable law, and, provided further, that in
no event does the term "Competing Transaction" include a sale or other
disposition of any non-coal assets.
 
    The Company must immediately advise Parent in writing of the receipt,
directly or indirectly, of any inquiries, discussions, negotiations, or
proposals relating to a Competing Transaction, which becomes known to the
Company's Board of Directors during the term of the Merger Agreement. The
Company must keep Parent fully apprised of the status and terms of any proposal
relating to a Competing Transaction on a current basis.
 
    If, prior to the purchase of Shares by the Purchaser pursuant to the Offer,
the Company's Board of Directors after consultation with its financial and legal
advisors determines in good faith that any written proposal from a third party
for a Competing Transaction received after the date of the Merger Agreement that
was not solicited by the Company or any of its subsidiaries in violation of the
Merger Agreement is more favorable to the stockholders of the Company from a
financial point of view than the transactions contemplated by the Merger
Agreement and is in the best interest of the stockholders of the Company,
 
                                       7
<PAGE>
the Company may terminate the Merger Agreement at any time prior to the purchase
of Shares by Purchaser and enter into a letter of intent,
agreement-in-principle, acquisition agreement or other similar agreement with
respect to such Competing Transaction provided that, (i) the Company provides
written notice of such termination to Parent at least three full business days
prior to the effectiveness of such termination, (ii) the Company delivers to
Parent within five business days following such termination cash in an amount
equal to Parent's costs as estimated by Parent in good faith prior to the date
of such delivery but in no event to exceed $10,000,000 and the Termination Fee
described below, and (iii) the Company and the other party to the Competing
Transaction deliver a written acknowledgment that the Company and such other
party have irrevocably waived any right to contest any payments as provided
above.
 
CONDITIONS TO CONSUMMATION OF THE MERGER
 
    The obligations of the Company, Parent and Purchaser to consummate the
Merger are subject to the satisfaction or, if appropriate, waiver of the
following conditions:
 
    PURCHASE OF SHARES.  The Purchaser shall have accepted for payment and paid
for Shares pursuant to the Offer in accordance with the terms of the Merger
Agreement, provided that the condition shall be deemed satisfied as to Parent
and Purchaser if Purchaser fails to accept for payment or pay for Shares
pursuant to the Offer in violation of the terms of the Offer. All conditions to
the Offer, which are set forth in Annex I to the Merger Agreement, are
summarized in Section 13.
 
    NO INJUNCTIONS OR RESTRAINTS; ILLEGALITY.  No order or preliminary or
permanent injunction shall be entered in any action or proceeding before any
court, and no statute, rule, regulation, legislation, or order shall be enacted,
entered, enforced, amended or issued by any United States legislative body,
court, government or governmental, administrative or regulatory authority or
agency (other than the waiting period provisions of the HSR Act) which shall
remain in effect and which shall have the effect of (x) making illegal or
restraining or prohibiting the making of the Offer, the acceptance for payment
of, or payment for, the Shares by Parent, Purchaser or any other affiliate of
Parent, or the consummation of the Offer or the Merger or (y) imposing
limitations on the ability of Purchaser effectively to acquire or hold or
exercise full rights of ownership of the Shares, including, without limitation,
the right to vote the Shares on all matters properly presented to the
shareholders of the Company; provided, that Parent, to the extent provided in
the Merger Agreement, shall, if necessary to prevent the taking of such action,
or the enactment, enforcement, amendment, issuance or application of any
statute, rule, regulation, legislation, judgment, order or injunction, offer to
accept an order to divest such of the Company's or Parent's assets and
businesses as may be necessary to forestall such injunction or order and to hold
separate such assets and business pending such divestiture; (ii) no proceeding
brought by an administrative agency or commission or other domestic governmental
entity seeking any of the foregoing shall be pending; and (iii) no action or
proceeding shall be commenced following the date of the Merger Agreement and be
pending before any court which, if adversely determined, could reasonably be
expected to have a material adverse effect on the Company.
 
TERMINATION; AMENDMENTS; WAIVER
 
    TERMINATION. The Merger Agreement provides that at any time prior to the
Effective Time the Merger Agreement may be terminated and the Merger may be
abandoned: (i) by the mutual written consent of Parent and the Company; (ii) by
the Company if the Purchaser fails to commence the Offer in accordance with the
Merger Agreement or fails to purchase validly tendered Shares in violation of
the terms of the Offer or the Merger Agreement; (iii) by Parent or Company if
the Offer is terminated or withdrawn without any Shares being purchased,
provided that neither Parent nor the Company may terminate the Merger Agreement
if such party materially breached the Merger Agreement, or in the case of
Parent, if it or the Purchaser materially violated the terms of the Offer; (iv)
by Parent or the Company to the extent that performance is prohibited, enjoined
or otherwise materially restrained by any final, non-appealable
 
                                       8
<PAGE>
judgment, provided the party seeking to terminate the Merger Agreement has used
its reasonable efforts to remove such judgment; (v) by Parent or the Company if
(a) the Financing Condition shall be impossible to satisfy by the end of the
twentieth business day following commencement of the Offer, or (b) any of the
conditions to the Offer shall be impossible to satisfy by the end of the
thirtieth business day following commencement of the Offer unless such
circumstance results from the failure of the terminating party to perform its
obligations under the Merger Agreement, provided that the Company may not
terminate the Merger Agreement if Parent is willing to waive the relevant
condition (other than the Minimum Condition, which cannot be waived without the
consent of the Company); (vi) by Parent if, prior to the purchase of Shares by
Purchaser, the Company's Board of Directors withdraws or modifies in a manner
adverse to Parent, or refrains from making the Board Recommendation, or publicly
discloses its intention to change such recommendation, or fails to reaffirm the
Board Recommendation within five days of receipt from Parent or the Purchaser of
a request to so reaffirm the Board Recommendation; (vii) by the Company prior to
the purchase of Shares pursuant to the Offer, if the Board after consultation
with its financial and legal advisors determines in good faith that any written
proposal from a third party for a Competing Transaction received after the date
of the Merger Agreement that was not solicited by the Company or any of its
Subsidiaries or affiliates in violation of the Merger Agreement is more
favorable to the stockholders of the Company from a financial point of view than
the transactions contemplated by the Merger Agreement and is in the best
interest of the stockholders of the Company; (viii) by the Company in the event
of any breach of the covenants and/or representations and warranties of Parent
and Purchaser contained in the Merger Agreement which has a material adverse
effect on the consummation of the transactions contemplated by the Merger
Agreement; or (ix) by Parent, if any Stockholder who holds more than five
percent of the Shares breaches any of his, her or its obligations under his, her
or its Support Agreement, as defined below.
 
    EFFECT OF TERMINATION; FEES AND EXPENSES.  Purchaser must terminate the
Offer as soon as practicable following the termination of the Merger Agreement
for any reason. If the Merger Agreement is terminated as a result of (i) the
Company's Board of Directors withdrawing its recommendation or (ii) the
Company's Board of Directors entering into a Competing Transaction, the Company
will repay Parent in cash an amount equal to the aggregate amount of reasonable
documented expenses not to exceed $10,000,000 and a termination fee of
$18,000,000.
 
    AMENDMENT.  The Merger Agreement may be amended by the Company, Parent and
Purchaser in a writing signed on behalf of each of the parties; however, after
the purchase of Shares pursuant to the Offer, no amendment may be made to
decrease the Merger Consideration or which materially adversely affects the
rights of the shareholders without approval of such shareholders.
 
    EXTENSION; WAIVER.  Subject to approval by the Company's Board of Directors
in the manner described above under "Board Representation," at any time prior to
the Effective Time, the Company, on the one hand, and Parent and Purchaser, on
the other hand, may in writing (i) extend the time for the performance of any of
the obligations or other acts of the other party, (ii) waive any inaccuracies in
the representations and warranties of the other party or (iii) waive compliance
by the other party with any of the agreements or conditions contained in the
Merger Agreement.
 
ITEM 4.   THE SOLICITATION OR RECOMMENDATION
 
    (a) RECOMMENDATION OF THE BOARD OF DIRECTORS. The Board has unanimously
determined that the Offer and the Merger are fair to and in the best interests
of the Company and its stockholders, has approved the Merger Agreement and the
transactions contemplated thereby, including the Offer and the Merger, and
recommends that all holders of Shares accept the Offer and tender their Shares
pursuant to the Offer and approve and adopt the Merger Agreement and the Merger.
 
                                       9
<PAGE>
    (b) BACKGROUND; REASONS FOR THE RECOMMENDATION. The Company's Board of
Directors has regularly discussed the Company's performance, consolidation in
the coal industry and various coal properties that were for sale, operational
issues affecting the Company, the level of the Company's stock price and other
factors. As a result of these discussions, the Board at a meeting on December 1,
1997, authorized Messrs. Manley and Reilly, acting as a special committee of the
Board (the "Special Committee"), to interview investment banking firms to assist
the Company in exploring various alternatives to maximize shareholder value,
including a possible sale of the Company. Shortly thereafter, the Company issued
a press release announcing such action. At a meeting on December 18, 1997, the
Board authorized the retention of Credit Suisse First Boston Corporation
("CSFB"), and such firm was retained to act as financial advisor to assist the
Company in this regard.
 
    At such Board meeting, representatives of CSFB reviewed with the Board
various potential alternatives that the Company could consider in order to
maximize shareholder value, including the sale of certain assets of the Company
and the sale of the entire Company. Following discussion of these alternatives,
the Board instructed CSFB to initiate a process for exploring a sale of the
Company or certain of its assets and to prepare an offering memorandum for that
purpose. During January and early February 1998, a confidential offering
memorandum (the "MEMORANDUM") was prepared describing the Company's coal
operations and properties and including historical and projected financial data
regarding the Company. Beginning on February 5, 1998, the Memorandum was sent to
69 prospective purchasers. The prospective purchasers were selected by the
Special Committee and the Company's management, after discussion with CSFB, as
parties that might be interested in the acquisition of the Company or principal
coal properties of the Company, and included companies in the coal and energy
industries as well as financial buyers. At the beginning of March, preliminary
bids were received from seven prospective purchasers who expressed an interest
in acquiring the entire Company and from other prospective purchasers who
indicated various levels of interest in certain assets of the Company. Following
the receipt of preliminary bids, representatives of Addington Enterprises, Inc.
("AEI") and another prospective investor (the "PROSPECTIVE INVESTOR"), two of
the prospective purchasers who had received copies of the Memorandum, requested
and were permitted to act jointly in connection with a possible acquisition of
the Company. Based on the preliminary bids, five prospective purchasers
(including the two who determined to proceed jointly) attended presentations by
management regarding the Company's historical and projected operations and four
prospective purchasers (including three who had attended the management
presentations) visited certain coal mines and other properties of the Company.
Following the preliminary indications of interest the Special Committee
requested its advisors to further evaluate the alternative of selling the
Company's assets to several purchasers.
 
    On April 7, 1998 certain of the prospective purchasers were provided with
copies of a form of acquisition agreement prepared by the Company's counsel
pursuant to which the buyer would acquire the Company in a two step transaction
involving a cash tender offer followed by a merger. Recipients were advised to
indicate any changes to the form of acquisition agreement as part of any final
bid they might make to acquire the Company. Final bids were received on May 22,
1998. Following analysis and discussion of the bids among the Special Committee
and the other directors of the Company and the Company's legal and financial
advisors, the Board authorized negotiations with respect to the joint bid
submitted by Parent, a newly formed holding company for the natural resource
operations conducted by AEI, and the Prospective Investor (the "Joint Venture")
which had bid to purchase the Company in a cash merger transaction for $21.25
per Share. Following discussions between representatives of CSFB and the Joint
Venture which clarified certain aspects of the Joint Venture's bid, the Company
and the Joint Venture entered into an agreement to negotiate for sale of the
Company exclusively with the Joint Venture until June 25, 1998. Such
negotiations occurred between representatives of the Joint Venture and the
Company's legal and financial advisors on behalf of the Company through July 7,
1998, at which time representatives of the Prospective Investor advised Mr.
Manley that the Prospective Investor had been unable to reach agreement with
Parent concerning the terms and structure of the Joint Venture and that
accordingly the Prospective Investor would not be involved in an acquisition of
the Company.
 
                                       10
<PAGE>
    On July 10, 1998, representatives of Parent informed the Company's financial
advisor that Parent was interested in acquiring the Company without the
participation of the Prospective Investor and with financing to be arranged by
Warburg Dillon Read LLC ("WDR"). After discussion with and instruction from Mr.
Manley (who had reviewed the matter with other directors), representatives of
CSFB advised representatives of Parent and WDR of the circumstances under which
a proposal to purchase the Company would be considered, including the
requirement that adequate financing be available so that a tender offer for any
and all of the Company's Shares could close the week of August 31. During the
week of July 27, Parent obtained financing commitments from USB AG, Stamford
Branch, necessary to fund the acquisition of the Company, including a bridge
loan commitment and a bank loan commitment sufficient to close a tender offer
for the Company's common stock, subject to various conditions, during the week
of August 31, 1998. The Company's representatives had provided a form of
acquisition agreement to the representatives of Parent on July 20, 1998, which
agreement was negotiated between representatives of Parent and the Company
during the week of July 27. By July 31, the principal terms of the acquisition
were agreed upon and set forth in a draft merger agreement. Prior to the meeting
of the Board that was held on August 3, the draft Merger Agreement, financing
commitments and a copy of CSFB's financial presentation were sent to each
director of the Company. On August 3, the Board of Directors of the Company met
to consider the sale of the Company contemplated by the Merger Agreement. At the
meeting, the Board reviewed and discussed with management and the Company's
legal and financial advisors the proposed Merger Agreement, the financing
commitments, the process leading up to the transaction contemplated by the
Merger Agreement and other matters. CSFB rendered to the Board its opinion to
the effect that, as of such date and based upon and subject to certain matters
stated in such opinion, the $21.25 per Share cash consideration to be received
by holders of Shares (other than Parent and its affiliates) pursuant to the
Offer and the Merger was fair to such holders from a financial point of view.
Following discussion, the Board of Directors approved the Merger Agreement and
resolved to recommend acceptance of the Offer to the Company's stockholders.
Each of the directors also agreed to tender his Shares in the Offer and each of
the directors, other than Mr. Ericson, executed an agreement with the Company
setting forth his obligation to tender such Shares.
 
    In approving the Merger Agreement and the transactions contemplated thereby
and recommending that all holders tender their Shares pursuant to the Offer, the
Board considered a number of factors, including the following:
 
    (i)  the Board's familiarity with, and information provided by the Company's
management as to, the business, financial condition, results of operations,
current business strategy and future prospects of the Company, material
developments affecting the coal and energy industries, the nature of the markets
in the coal industry and the Company's position in such markets, the historical
and current market prices for the Common Stock and the costs, uncertainties and
risks of seeking to grow through acquisition of substantial coal properties;
 
    (ii) a consideration of strategic and other alternatives to the sale of the
Company, including the sale of certain assets of the Company, the development of
proposals with other parties and continuing to maintain the Company as a public
corporation and not engaging in any extraordinary transaction, and the
information provided by CSFB as to such alternatives;
 
    (iii) the terms of the Merger Agreement, including the financing condition
and the other conditions to the Offer, the terms of the financing commitments
issued by WDR and the business reputation of WDR;
 
    (iv) that the $21.25 per Share price contemplated by the Merger Agreement
represented a significant premium to the trading prices of the Shares prior to
the announcement of the process to seek strategic alternatives, and, later,
prior to announcement of the Tender Offer, and represented the highest cash
price any potential acquiror of the entire Company was willing to offer on
acceptable terms;
 
                                       11
<PAGE>
    (v) the process undertaken on behalf of the Company, which included
discussions with potential acquirors, as a result of which the Board had what it
believed to be an accurate sense of the values that could be achieved in a third
party transaction;
 
    (vi) the opinion of CSFB dated August 3, 1998 to the effect that, as of such
date and based upon and subject to certain matters stated in such opinion, the
$21.25 per Share cash consideration to be received by holders of the Shares
(other than Parent and its affiliates) in the Offer and the Merger was fair,
from a financial point of view, to such holders. The full text of CSFB's written
opinion dated August 3, 1998, which sets forth the assumptions made, matters
considered and limitations on the review undertaken by CSFB, is attached hereto
as Exhibit 3 and is incorporated herein by reference. CSFB'S OPINION IS DIRECTED
ONLY TO THE FAIRNESS, FROM A FINANCIAL POINT OF VIEW, OF THE CASH CONSIDERATION
TO BE RECEIVED IN THE OFFER AND THE MERGER BY HOLDERS OF SHARES (OTHER THAN
PARENT AND ITS AFFILIATES) AND IS NOT INTENDED TO CONSTITUTE, AND DOES NOT
CONSTITUTE, A RECOMMENDATION OF CSFB AS TO WHETHER ANY STOCKHOLDER SHOULD TENDER
SHARES PURSUANT TO THE OFFER. HOLDERS OF SHARES ARE URGED TO READ SUCH OPINION
CAREFULLY IN ITS ENTIRETY;
 
    (vii) that the Merger Agreement permits the Company to furnish nonpublic
information to, and to participate in negotiations with, any third party that
has submitted an unsolicited written acquisition proposal to the Company, if the
Board determines in good faith that taking such action is necessary in the
exercise of its fiduciary obligations under applicable law and the Merger
Agreement permits the Company's Board to terminate the Merger Agreement in
certain circumstances in the exercise of its fiduciary duties;
 
    (viii) the termination provisions of the Merger Agreement, which under
certain circumstances could obligate the Company to pay termination fees to
Parent and, subject to limitation, to reimburse Parent for its actual expenses
incurred in connection with the transaction, and the Board's belief that such
fees and expense reimbursement provisions are acceptable in view of the short
duration of the Tender Offer, the length of time since the public announcement
that the Company was exploring strategic opportunities to maximize shareholder
value, including a possible sale of the Company, and the process conducted on
behalf of the Company leading to the approval of the Merger Agreement;
 
    (ix) the desirability of providing liquidity to holders of substantial
amounts of the Shares; and
 
    (x) strategic considerations, such as the Company's competitive position and
the rapid changes, including consolidation, currently occurring in the coal
industry.
 
    The foregoing discussion addresses the material information and factors
considered by the Board in its consideration of the Offer. In view of the
variety of factors, the amount of information considered and the relationships
between the various factors the Board did not find it practicable to provide
specific assessments of, quantify or otherwise assign relative weights to the
specific factors considered in reaching its determination. The determination to
recommend that stockholders accept the Offer was made after consideration of all
of the factors taken as a whole. In addition, individual members of the Board
may have given different weights to different factors.
 
ITEM 5.   PERSONS RETAINED, EMPLOYED OR TO BE COMPENSATED
 
    The Company has retained CSFB as its financial advisor in connection with
the Offer and the Merger. Pursuant to the terms of CSFB's engagement, the
Company has agreed to pay CSFB for its services an aggregate financial advisory
fee equal to 0.7% of the total consideration (including net debt assumed)
payable in connection with the Offer and the Merger. The Company also has agreed
to reimburse CSFB for reasonable out-of-pocket expenses, including the fees of
legal counsel and any other advisor retained by CSFB, and to indemnify CSFB and
certain related parties against certain liabilities, including liabilities under
the federal securities laws, arising out of CSFB's engagement. CSFB has in the
past provided financial services to the Company unrelated to the Offer and the
Merger, for
 
                                       12
<PAGE>
which services CSFB has received compensation. In the ordinary course of
business, CSFB and its affiliates may actively trade or hold the securities of
the Company for their own account or for the account of customers and,
accordingly, may at any time hold a long or short position in such securities.
 
    Neither the Company nor any person acting on its behalf currently intends to
employ, retain or compensate any person to make solicitations or recommendations
to stockholders on its behalf concerning the Offer.
 
ITEM 6.   RECENT TRANSACTIONS AND INTENT WITH RESPECT TO SECURITIES
 
    (a) To the knowledge of the Company, no transactions in Shares have been
effected within the past 60 days by the Company or any executive officer,
director, affiliate or subsidiary of the Company, other than routine
contributions to the Ziegler Stock Fund under the Company's 401(k) plan. See
Item 8 below, which sets forth certain information as to certain related
matters.
 
    (b) To the knowledge of the Company, its executive officers, directors,
affiliates and subsidiaries presently intend to tender, pursuant to the Offer,
all Shares which are held of record or are beneficially owned by such persons.
Each of the directors has agreed to tender his Shares in the tender offer and
each of the directors, other than Mr. Ericson, has executed an agreement with
the Company setting forth his obligation to tender such Shares.
 
ITEM 7.   CERTAIN NEGOTIATIONS AND TRANSACTIONS BY THE SUBJECT COMPANY
 
    (a) Except as set forth in this Schedule 14D-9, the Company is not engaged
in any negotiation in response to the Offer which relates to or would result in
(i) an extraordinary transaction, such as a merger or reorganization, involving
the Company or any subsidiary of the Company; (ii) a purchase, sale or transfer
of a material amount of assets by the Company or any subsidiary of the Company;
(iii) a tender offer for or other acquisition of securities by or of the
Company; or (iv) any material change in the present capitalization or dividend
policy of the Company.
 
    (b) None.
 
ITEM 8.   ADDITIONAL INFORMATION TO BE FURNISHED
 
    The following information is in addition to the information set forth in
Item 4.
 
    CERTIFICATE OF INCORPORATION. The Company's Restated Certificate of
Incorporation, as amended (the "CERTIFICATE OF INCORPORATION"), contains certain
provisions that may delay, defer or prevent a takeover of the Company. The
Company's Board of Directors has the authority to issue up to 1,000,000 shares
of preferred stock (the "PREFERRED STOCK") and to determine the price, rights,
preferences, privileges and restrictions, including voting rights, of these
shares, without further vote or action by the stockholders. The purpose of
authorizing the Board of Directors to determine such rights and preferences is
to eliminate delays associated with a stockholder vote on specific issuances.
The Board of Directors may issue Preferred Stock with voting, conversion and
exchange rights which would adversely affect the voting power of the holders of
Common Stock, and which could, among other things, have the effect of delaying,
deferring or preventing a change in control of the Company.
 
    One of the effects of the existence of unissued and unreserved Common Stock
and Preferred Stock may be to enable the Board of Directors to issue shares to
persons friendly to current management which could render more difficult or
discourage an attempt to obtain control of the Company by means of a merger,
tender offer, proxy contest or otherwise, and thereby protect the continuity of
the Company's management. Such additional shares also could be used to dilute
the stock ownership of persons seeking to obtain control of the Company. In the
Merger Agreement, the Company has agreed not to issue any such additional
shares.
 
                                       13
<PAGE>
    The Company is subject to the "business combination" section of the Delaware
General Corporation Law. In general, such statute prohibits a publicly held
Delaware corporation from engaging in various "business combination"
transactions with any "interested stockholder" for a period of three years after
the date of the transaction in which the person became an "interested
stockholder," unless (i) the business combination or the transaction in which
the person becomes an interested stockholder is approved by the Board of
Directors prior to the date the interested stockholder obtained such status,
(ii) upon consummation of the transaction which resulted in the stockholder
becoming an "interested stockholder," the "interested stockholder" owned at
least 85% of the voting stock of the corporation outstanding at the time the
transaction commenced, excluding for purposes of determining the number of
shares outstanding those shares owned by (a) persons who are directors and also
officers and (b) employee stock plans in which employee participants do not have
the right to determine confidentially whether shares held subject to the plan
will be tendered in a tender or exchange offer, or (iii) on or subsequent to
such date the "business combination" is approved by the Board of Directors and
authorized at an annual or special meeting of stockholders by the affirmative
vote of at least 66 2/3% of the outstanding voting stock which is not owned by
the "interested stockholder." A "business combination" includes mergers, asset
sales and other transactions resulting in financial benefit to a stockholder. An
"interested stockholder" is a person who owns 15% or more of a corporation's
voting stock or is an affiliate or associate of the corporation and was the
owner of 15% or more of its voting stock at any time within the three year
period prior to the transaction. The statute could prohibit or delay mergers or
other takeover or change in control attempts with respect to the Company and,
accordingly, may discourage attempts to acquire the Company.
 
    The foregoing summary of the Certificate of Incorporation is qualified in
its entirety by reference to the Certificate of Incorporation, a copy of which
is filed as Exhibit 4 to this Statement and is incorporated herein by reference.

                       INFORMATION STATEMENT PURSUANT TO
                        SECTION 14(F) OF THE SECURITIES
                 EXCHANGE ACT OF 1934 AND RULE 14F-1 THEREUNDER
 
    This Information Statement is being mailed on or about August 5, 1998 as a
part of the Solicitation/ Recommendation Statement on Schedule 14D-9 (the
"Schedule 14D-9") of Zeigler Coal Holding Company (the "Company") to the holders
of record of shares of Common Stock, $.01 par value, of the Company (the
"Shares" or "Common Stock"). You are receiving this Information Statement in
connection with the possible election of persons designated by Parent (as
defined below) to a majority of the seats on the Board of Directors of the
Company (the "Board of Directors").
 
    On August 3, 1998, the Company, AEI Resources, Inc., a Delaware corporation
("Parent"), and Zeigler Acquisition Corporation ("Purchaser"), a Delaware
corporation and a wholly owned subsidiary of Parent, entered into an Agreement
and Plan of Merger (the "Merger Agreement") and, in accordance with the terms
and subject to the conditions therein, (i) Parent and Purchaser commenced a
tender offer (the "Offer") for any and all outstanding Shares at a price of
$21.25 per Share, net to the seller in cash, without interest thereon (the
"Purchase Price"), and (ii) at the Effective Time (as such term is defined in
the Merger Agreement), Purchaser will be merged with and into the Company (the
"Merger"). As a result of the Offer and the Merger, the Company will become a
wholly owned subsidiary of Parent.
 
    The Merger Agreement provides that, promptly upon the purchase of Shares by
Parent or Purchaser pursuant to the Offer, Purchaser will be entitled to
designate at least a number of directors on the Company's Board of Directors
equal to the product of (i) the total number of directors on the Company's Board
of Directors and (ii) Purchaser's percentage ownership of the outstanding Shares
of the Company. The Company will either increase the size of the Company's Board
of Directors or secure the resignation of the necessary number of directors to
enable Purchaser's designees to be elected to the Company's Board of Directors,
and will cause such designees to be elected to the Company's Board of Directors.
The Company expects that all of the current members of the Board of Directors
will resign effective upon the purchase of Shares by Parent or Purchaser
pursuant to the Offer. The Purchaser intends to designate five individuals for
election to the Board of Directors, who would constitute all of the Company's
directors upon the consummation of the Merger and the resignation of all of the
Company's current directors. This Information Statement is required by Section
14(f) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
and Rule 14f-1 thereunder.
 
    The following information is given as of the date of the Schedule 14D-9,
August 5, 1998, unless indicated otherwise. You are urged to read this
Information Statement carefully. You are not, however, required to take any
action. Capitalized terms used herein and not otherwise defined herein shall
have the meaning set forth in the Schedule 14D-9.
 
    Pursuant to the Merger Agreement, the Purchaser commenced the Offer on
August 5, 1998. The Offer is scheduled to expire at 12:00 midnight, New York
City time, on Tuesday, September 1, 1998, unless extended.
 
    The information contained in this Information Statement concerning Parent
and Purchaser has been furnished to the Company by the Parent, and the Company
assumes no responsibility for the accuracy or completeness of such information.
 
                CERTAIN INFORMATION WITH RESPECT TO THE COMPANY

Executive Officer at an annual salary and bonus to be determined by the Board of
Directors. Mr. Vyas' employment may be terminated by him or the Company on 30
days' notice. If he is terminated for other than cause, or he terminates his
employment as a result of an unacceptable change in his duties, a change of
control of Zeigler or other "Good Reason" (as defined therein), Mr. Vyas would
be entitled to severance payments for three years following termination in an
amount equal to three times his Average Compensation as well as certain other
benefits related to his supplemental retirement payments and acceleration of
vesting of his stock options. In the event of Mr. Vyas' death, his estate is
entitled to receive two times his Average Compensation. The employment agreement
provides that upon retirement, Mr. Vyas would be entitled to supplemental
retirement payments equal to the excess, if any, of (i) the amount he would
receive under the Company's pension plan (described below) if effect were not
given to limitations imposed by the Internal Revenue Code and if his
compensation included his bonuses over (ii) the annual amount payable to Mr.
Vyas under such pension plan plus annual social security benefits payable to
him. The estimated annual supplemental retirement payment payable to Mr. Vyas
upon his normal retirement date was $315,000 as of December 31, 1997. Mr. Vyas'
employment agreement also provides that he will not compete with the Company
during the employment term and for a period of one year following termination.
 
CHANGE IN CONTROL ARRANGEMENTS
 
    SPECIAL BONUS AND SEVERANCE PAY PLAN. In December, 1997, Zeigler announced
that it was reviewing strategic alternatives to increase stockholder value,
including a possible sale of the Company. In connection therewith Zeigler
adopted a special bonus and severance pay plan which provides that certain of
Zeigler's executives and other non-union personnel would receive specified
retention payments if a sale of Zeigler or other change of control (as defined
in the plan) occurred prior to December 31, 1998 and severance payments if the
employment of such person were terminated in certain circumstances during the
twelve months following such sale or other change of control. The plan also
provides that any unvested stock options will vest upon a sale of the Company or
other change in control. Any severance payment otherwise due an executive under
this plan would be reduced by severance amounts payable under his or her
employment contract. The amounts of such payments vary based on the
classification of the covered employee and his or her compensation level and
tenure with the Company. The amounts payable to Messrs. Blackburn, Willson, Lane
and Young under the plan, as of April 2, 1998 are: $220,000.00, $164,983.50,
$143,550.00 and $164,983.50 respectively, in the event of change in control and
$440,000.00, $330,016.50, $291,450.00 and $330,016.50, in the event such
individual becomes entitled to severance payments (after reduction of the amount
paid upon a change in control). In addition, if a sale of the Company occurs
during 1998 each of the named individuals would be entitled to receive a special
bonus of $150,000 and possibly other payments determined in the discretion of
Messrs. Manley and Reilly. Change in control arrangements applicable to Mr. Vyas
are discussed in "Employment Agreements" above.
 
STOCK APPRECIATION AND STOCK OPTION PLANS
 
    STOCK APPRECIATION PLAN. Certain key employees of the Company and its
subsidiaries have been granted stock appreciation units ("SAUs") under the
Company's Stock Appreciation Plan (the "Stock Appreciation Plan"). Each
participant in the Stock Appreciation Plan is entitled to receive a cash payment
at "maturity" for each SAU which has become vested based upon the increase in
fair value (as defined) of a share of the Company's Common Stock from the
effective date of the award of the SAU. Vested SAUs mature on the earliest of
the termination of the participant's employment with the Company, the sixth
anniversary of the date of grant, the sale of the Company or the written
election of the participant. The Stock Appreciation Plan is administered by the
Compensation Committee of the Board of Directors. There were 73,600 SAUs
outstanding as of December 31, 1997, all of which are fully vested and mature in
1998. Under the Stock Appreciation Plan, "fair value" is based on the "market
price" of the Company's Common Stock.
 
                                       7
<PAGE>
    STOCK OPTION PLAN. In 1994 the Company's Board of Directors and stockholders
adopted its Stock Option Plan (the "Option Plan"). A total of 2,560,000 shares
of Common Stock were reserved for issuance upon exercise of options granted
under the Option Plan. The purpose of the Option Plan is to attract and retrain
qualified personnel and to provide additional incentive to executive and other
key employees of the Company and its subsidiaries. The Option Plan is
administered by the Compensation Committee (the "Committee") which determines
the terms of the options granted under the Option Plan, including the exercise
price, number of shares subject to the option and exercisability. Generally,
options may be transferred by the optionees by will or the laws of descent or
distribution or to such transferees and on such terms and conditions as the
Committee approves. Each option may be exercised, during the lifetime of the
optionee, only by the optionee. The exercise price of all options granted under
the Option Plan must equal at least the fair market value of the Common Stock of
the Company on the date of grant.
 
    Unless the Committee specifies otherwise in the option grant, options
granted will vest and become exercisable with respect to 20% of the Common Stock
issuable upon exercise thereof on each anniversary of the grant date, and the
reminder shall vest on the fifth anniversary of the grant date. At the
discretion of the Committee, options may be made exercisable in one or more
installments upon (i) occurrence of certain events, (ii) passage of time, (iii)
fulfillment of certain conditions, or (iv) achievement of corporate performance
goals. In the event of the Sale of the Company (as defined therein), the
Committee may provide, in its discretion, that (i) outstanding options shall
become immediately exercisable and shall terminate if not exercised as of the
date of the Sale of the Company or any other designated date, or (ii) that such
options shall only provide the right to receive the excess of the consideration
per share of Common Stock offered in such Sale of the Company over the exercise
price of such options.

RETIREMENT PLANS
 
    All non-union employees of Zeigler Coal Holding Company and its subsidiaries
are eligible to participate in the Mining Companies Pension Plan, a defined
benefit pension plan intended to qualify under Section 401(a) of the Code (the
"pension plan"). The pension plan is a cash balance plan whereby each
participant's benefit is determined based upon the assumed cash balance credits
and earnings which are credited to the participant's nominal account. The cash
balance credits range from 5% to 6.5% of the participant's annual compensation.
Each account is credited with assumed earnings equal to the 5-year Treasury note
rate, subject to a 5% minimum and a 12% maximum rate. The normal retirement age
under pension plan is age 60. Certain participants under this plan may be
entitled to a minimum benefit under the pension plan equal to the amount which
would have been provided under a prior defined benefit formula.
 
    Compensation under the pension plan generaly refers to the base salary (up
to $150,000 for 1997 as limited by the Code) for services rendered to the
Company and its subsidiaries including pre-tax deferrals, but excluding items
such as bonuses, the value of stock awards and employer contributions to
retirement plans at December 31, 1997. As of December 31, 1997, the estimated
annual benefit (assuming a 7.5% return on each participant's nominal account)
payable to Messrs. Vyas, Blackburn, Willson, Lane and Young upon their normal
retirement date was $53,657, $27,438, $19,860, $65,680, and $37,155,
respectively. As of December 31, 1997, Messrs, Vyas, Blackburn, Willson, Lane
and Young had approximately 16, 3, 2, 3, and 13 years of credited service,
respectively, under the pension plan. Benefits are computed on a straight life
annuity basis and payable under several actuarially determined alternatives.
 
    All non-union employees of Zeigler Coal Holding Company are also eligible to
participate in either the Zeigler Salaried Employees Savings Plan or the Mining
Companies Pay Deferral Plan, defined contribution 401(k) plans intended to
qualify under Section 401(a) of the Code (the "savings plan"). Participants may
contribute to the savings plan on a pre-tax basis. The Company matches a portion
of the amount contributed under the Zeigler Salaried Employees Savings Plan. The
Company's matching contribution equals $.50 for each dollar contributed (not to
exceed 3% of compensation), plus an additional match (not to exceed another 3%
of compensation) if the Company meets certain performance criteria. The
compensation which may be considered for this purpose is limited by the Code to
 
                                       9
<PAGE>
$150,000 in 1997. There is generally no Company matching under the Mining
Companies Pay Deferral Plan.
 
CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    During 1997, the Company made a short-term loan for personal purposes to
Paul D. Femmer, Controller of the Company. This loan, the largest aggregate
amount outstanding of which was approximately $85,000 (including accrued
interest), bore interest at the rate of 10% per annum and was paid in full prior
to December 31, 1997.
 
    The Company intends to enter into an agreement with Paul Femmer and Chand
Vyas relating to the termination of Femmer's employment and other matters
arising out of business and employment relationships between Femmer, Vyas and
the Company and certain claims made by Femmer.
 
COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
    The Compensation Committee of Zeigler's Board of Directors has
responsibility for establishing the compensation (including employee benefits
not generally available to salaried employees) of the Company's principal
executive officers and other higher paid personnel. The Compensation Committee
also serves as the committee established under Zeigler's Stock Option Plan with
authority to fix the terms of, and grant options under, such plan. The
Compensation Committee is comprised solely of non-employee directors.
 
    In general, the Compensation Committee strives to meet the following
objectives in making compensation decisions for executive personnel: (1) provide
overall compensation that enables the Company to attract and retain highly
qualified personnel; (2) to authorize compensation that is fair to Zeigler
employees, fair to Zeigler shareholders, and fair comparing the different
organizational levels; and (3) to design compensation that creates both
substantial incentives as well as alignment with short and long term shareholder
interests.
 
    In general, the Committee does not intend to approve compensation to the
Company's executive officers in excess of $1,000,000, unless such compensation
meets the performance based standards set forth in Section 162(m)(4)(C) of the
Internal Revenue Code of 1986, as amended, or the Committee determines that such
compensation is otherwise appropriate in the specific instance. The Committee
consults with tax advisors as necessary to avoid any unintended results.
 
    There are currently three principal components of senior executive
compensation: (i) base salaries, (ii) annual cash bonuses and (iii) stock
options. Salaries are determined primarily on the basis of industry standards as
applied to each executive's background, responsibilities and overall performance
with the Company and are adjusted every 12 to 24 months. In general, the
Committee's policy has been to have the incentive based components of
compensation (i.e., bonuses and stock related plans) constitute a higher
proportion of an executive's overall compensation. In its review, the Committee
takes into account high growth goals for the Company balanced by the
complexities of transitioning from a pure coal mining company. The Committee has
also reviewed the compensation plans of high growth companies in a number of
industries. Details of this review include the dollar amounts of salaries and
bonuses, the relationship of stock options and bonuses to salaries, company
size, total shareholder return and shares outstanding; the alignment of
compensation between organization levels; and the breadth of incentive plans.
 
    Annual bonuses are considered to represent the short-term incentive portion
of executive compensation and are based on actual financial performance as
compared to the Company's financial plan as well as the assessment of the
executive's overall performance during the year. Financial performance is
measured principally by operating income cash flow of the Company and total
return to shareholders (based primarily on the value of the Company's shares).
In the case of officers responsible for a
 
                                       10
<PAGE>
particular business unit, the performance of that unit is a principal measure.
Targeted bonus amounts are set for each executive officer. With respect to 1997,
the Committee determined, based on the significant negative shareholder returns
during 1997, that neither Mr. Vyas nor Mr. Blackburn would receive a bonus. For
the other named executive offiers the Committee approved bonuses ranging from 9%
to 25% of their base salaries.
 
    Long-term incentives for executives are provided by Zeigler's Stock Option
Plan. Stock option grants under the Stock Option Plan are intended to provide
rewards which are earned by executives over a substantial period of employment
and which reflect growth in the value of stockholder equity and align the
interests of key personnel with those of stockholders. The policy of the
Compensation Committee is to consider option grants for executives annually and
has been to provide option vesting in annual increments over a number of years.
In making individual grants, the Committee also considers the amount and terms
of prior option grants to each individual. The Committee granted options for
100,000 shares to Mr. Vyas in 1997.
 
    Finally, in 1997, the Compensation Committee participated in the development
of the Special Bonus and Severance Pay Plan described elsewhere in this
Information Statement.

also to prescribe various conditions to the Offer and the Merger; and

         WHEREAS, certain capitalized terms used in this Agreement have the
meaning as set forth or referred to in Article X hereof.

         NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein, Parent,
the Purchaser and the Company agree as follows:


<PAGE>



                                    ARTICLE I

                                    THE OFFER

         SECTION 1.01 The Offer.

         (a) Provided that this Agreement shall not have been terminated in
accordance with its terms and none of the events set forth in Paragraphs (a)
through (f) of Annex I hereto shall have occurred or be existing, no later than
two (2) business days after the public announcement of the terms of this
Agreement, the Purchaser shall commence the Offer, in accordance with the
requirements of Regulations 14D and 14E promulgated under the Exchange Act, and
any applicable State securities laws, to purchase all of the issued and
outstanding Common Shares for the Offer Price net to the seller thereof in cash,
provided, however, that the Purchaser shall use its best efforts to commence the
Offer as soon as practicable after the public announcement of the terms of this
Agreement, but in no event later than two business days after such public
announcement. The Offer shall expire and terminate on the twentieth (20th)
business day from the commencement of the Offer (the "Expiration Date");
provided, however, that the Purchaser shall have the right to extend the
Expiration Date up to ten (10) additional business days in order to satisfy any
of the conditions set forth in Annex I hereto other than the Offer Financing
Condition, provided that the failure of such conditions to be satisfied is not
due to a breach of this Agreement by Parent or Purchaser. Provided that this
Agreement shall not have been terminated in accordance with its terms and none
of the events set forth in Paragraphs (a) through (f) of Annex I hereto shall
have occurred or be existing, no later than (2) two business days after the
public announcement of the terms of this Agreement, the Purchaser shall file
with the Securities and Exchange Commission (the "SEC") the Purchaser's Tender
Offer Statement on Schedule 14D-1 (together with any supplements or amendments
thereto, the "Offer Documents"), which shall contain (as an exhibit) the
Purchaser's offer to purchase the Common Shares (the "Offer to Purchase") which
shall be mailed to the holders of Common Shares with respect to the Offer, which
shall contain the conditions set forth in Annex I hereto and no others; it being
understood that the Offer shall be on the terms and subject to the conditions
that are agreed to by the parties hereto and no others and that the Purchaser
shall use its best efforts to file the Tender Offer Statement on Schedule 14D-1
as soon as practicable, but in no event later than two business days after such
public announcement. The obligation of Purchaser to accept for payment or pay
for any Common Shares tendered pursuant to the Offer will be subject only to the
satisfaction of the conditions set forth in Annex I hereto. Without the prior
written consent of the Company, the Purchaser shall not decrease the price per
Common Share or change the form of consideration payable in the Offer, decrease
the number of Common Shares sought to be purchased in the Offer, change the
conditions set forth in Annex I, waive the Minimum Condition (as defined in
Annex I), impose additional conditions to the Offer or amend any other term of
the Offer in any manner adverse to the holders of Common Shares; provided that
the Purchaser expressly reserves the right to waive any condition to the Offer
(other than the Minimum Condition) without the consent of the Company. Subject
to the terms of the Offer and this Agreement and the satisfaction of all the
conditions of the Offer set forth in Annex I hereto as of any expiration date,
Purchaser will accept for payment and pay for all Common Shares


<PAGE>


validly tendered and not withdrawn pursuant to the Offer as soon as practicable
after such Expiration Date (the time of such purchase being referred to herein
as the "Offer Purchase Closing"). Purchaser shall make reasonable provision for
the payment of Offer proceeds to be made by wire transfer of immediately
available funds to any person tendering Common Shares representing more than 1%
of the Company's outstanding Common Shares. Subject to Section 8.01, if any of
the conditions set forth in Annex I hereto are not satisfied or, to the extent
permitted by this Agreement, waived by the Purchaser as of the Expiration Date
(or any subsequently scheduled expiration date), Purchaser will extend the Offer
from time to time, in each case, for the shortest time period that it reasonably
believes is necessary for the consummation of the Offer. Each of the parties
hereto shall use its reasonable best efforts to cause all conditions precedent
set forth in Annex I to be fulfilled and avoid the occurrence of any event or to
cure any event which may prevent such conditions precedent set forth in Annex I
from being fulfilled.

         (b) The Offer Documents will comply in all material respects with the
provisions of applicable federal securities laws and, on the date filed with the
SEC and on the date first published, sent or given to the Company's
stockholders, shall not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements made therein, in light of the circumstances under which
they were made, not misleading, except that no representation is made by Parent
or the Purchaser with respect to information supplied by the Company in writing
for inclusion in the Offer Documents. Each of Parent and the Purchaser, on the
one hand, and the Company, on the other hand, agrees promptly to correct any
information provided by it for use in the Offer Documents if and to the extent
that it shall have become false or misleading in any material respect and the
Purchaser further agrees to take all steps necessary to cause the Offer
Documents as so corrected to be filed with the SEC and to be disseminated to
stockholders of the Company, in each case, as and to the extent required by
applicable federal securities laws.

         SECTION 1.02 Company Actions.

         (a) The Company shall promptly (and in any event within two (2)
business days after the public announcement of the terms of this Agreement) file
with the SEC and mail to the holders of Common Shares the Company's
Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the
Offer (together with any amendments or supplements thereto, the "Schedule
14D-9"). The Schedule 14D-9 will set forth, and the Company hereby represents,
that the Board, at a meeting duly called and held, has (i) determined that the
Offer and the Merger are fair to and in the best interests of the Company and
its stockholders, (ii) approved the Offer and the Merger in accordance with
Section 203 of the GCL, and (iii) resolved to recommend and continues to
recommend acceptance of the Offer and approval and adoption of the Merger and
this Agreement by the Company's stockholders (if such approval is required by
applicable law) (such recommendation to the Company's stockholders being
referred to as the "Board Recommendation"); provided, however, that such
recommendation and approval may be 

<PAGE>

withdrawn, modified or amended as provided in Section 6.09. The Company further
represents that Credit Suisse First Boston Corporation ("CSFB") has delivered to
the Board its written opinion to the effect that, as of the date of this
Agreement, the cash consideration to be received for the Common Shares pursuant
to the Offer and the Merger is fair to the holders of the Common Shares (other
than Parent and its affiliates) from a financial point of view.



         (b) Each of the Company, on the one hand, and Parent and the Purchaser,
on the other hand, agree promptly to correct any information provided by either
of them for use in the Schedule 14D-9 if and to the extent that it shall have
become false or misleading, and the Company further agrees to take all steps
necessary to cause the Schedule 14D-9 as so corrected to be filed with the SEC
and to be disseminated to the holders of the Common Shares, in each case, as and
to the extent required by applicable federal securities law.

         (c) In connection with the Offer, the Company will use reasonable best
efforts to cause to be furnished to Purchaser mailing labels, security position
listings and any available listing or computer file containing the names and
addresses of the record holders of the Shares as of a recent date and shall
furnish Purchaser with such additional information and assistance (including,
without limitation, updated lists of stockholders, mailing labels and lists of
securities positions) as Purchaser or its agents may reasonably request in
communicating the Offer to the record and beneficial holders of Shares. Subject
to the requirements of applicable law, and except for such steps as are
necessary to disseminate the Offer Documents and any other documents necessary
to consummate the Merger, Purchaser and its affiliates and associates shall hold
in confidence the information contained in any such labels, listings and files,
will use such information only in connection with the Offer and the Merger, and,
if this Agreement shall be terminated, will deliver to the Company all copies of
such information then in their possession.

         SECTION 1.03 Directors.

         (a) Subject to compliance with applicable law, promptly upon the
payment by the Purchaser for Common Shares pursuant to the Offer, and from time
to time thereafter, Parent shall be entitled to designate at least such number
of directors, rounded up to the next whole number, on the Board as is equal to
the product of the total number of directors on the Board (determined after
giving effect to the directors elected pursuant to this sentence) multiplied by
the percentage that the aggregate number of Common Shares beneficially owned by
Parent or its affiliates bears to the total number of Common Shares then
outstanding, and the Company shall, upon request of Parent, promptly take all
actions necessary to cause Parent's designees to be so elected, including, if
necessary, seeking the resignations of one or more existing directors.

         (b) The Company's obligations to appoint Parent's designees to the
Board shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1
thereunder. The Company shall promptly take all actions required pursuant to
such Section and Rule in order to fulfill its obligations under this Section
1.03 and shall include in the Schedule 14D-9 such information with respect to
the Company and its officers and directors as is required under such Section and
Rule in order to fulfill its obligations under this Section 1.03. Parent will
supply any information with respect to itself and its officers, directors and
affiliates required by such Section and Rule to 

<PAGE>

the Company.

         (c) Following the election or appointment of Parent's designees
pursuant to this Section 1.03 and prior to the Effective Time, any amendment or
termination of this Agreement by the Company, the Company shall not extend the
time for the performance of any of the obligations or other acts of Parent or
the Purchaser or waive any of the Company's rights hereunder, or take any other
action if such amendment, termination, extension, waiver or action would have an
adverse effect on the minority stockholders of the Company.



         SECTION 1.04 Stock Options. Promptly following the commencement of the
Offers the Company shall offer to cancel any or all of the outstanding options
to purchase Common Shares and each outstanding stock appreciation unit (each
such option to purchase one share and each such unit representing one share
being referred to as an "Option") granted under the Company's Incentive Stock
Option Plan and the Company's Stock Appreciation Rights Plan (collectively the
"Option Plan") for cash consideration as set forth herein. Each holder of an
Option which is vested (after giving consideration to any acceleration of
vesting provided in the Option Plan or the Company's Special Bonus and Severance
Plan (the "SBS Plan")) shall be offered the right to have 100% of his or her
Options canceled by the Company in consideration of a payment by the Company to
such holder for each Option in an amount equal to the excess of the Offer Price
over the applicable exercise price of such Option. Cancellation of the Options
and payment of the consideration therefor shall be conditioned upon the purchase
of Common Shares by the Purchaser pursuant to the Offer. If such condition is
met, the cancellation of Options and payment of the consideration therefor in
accordance with this section shall be made as promptly as possible following the
Offer Purchase Closing.

                                   ARTICLE II

                                   THE MERGER

         SECTION 2.01 The Merger. Upon the terms and subject to the satisfaction
or waiver of the conditions of this Agreement, and in accordance with the
applicable provisions of this Agreement and the GCL, at the Effective Time (as
defined in Section 2.02) the Purchaser shall be merged with and into the
Company. Following the Merger, the separate corporate existence of the Purchaser
shall cease and the Company shall continue as the surviving corporation and
shall succeed to and assume all the rights and obligations of Purchaser in
accordance with the GCL. In its capacity as the surviving corporation of the
Merger, the Company is sometimes referred to herein as the "Surviving
Corporation."

         SECTION 2.02 Closing Effective Time. The closing of the Merger (the
"Closing") will take place as promptly as practicable following the satisfaction
or waiver of the conditions set forth in Section 7.01 of this Agreement (the
"Closing Date"), at the offices of Brown, Todd & Heyburn PLLC, Lexington, KY.
Immediately following the Closing, the parties hereto shall cause the Merger to
become effective by filing a Certificate of Merger or, if 

<PAGE>

permitted, a Certificate of Ownership and Merger, with the Secretary of State of
the State of Delaware, in accordance with the relevant provisions of the GCL
(the time of such filing being the "Effective Time") and shall make all other
filings or recordings required under the GCL.




         SECTION 2.03 Effects of the Merger.

         (a) The Merger shall have the effects set forth in the GCL.

         (b) The Certificate of Incorporation of the Company, as in effect
immediately prior to the Effective Time, shall be the Certificate of
Incorporation of the Surviving Corporation, until thereafter amended in
accordance with the provisions thereof and hereof and applicable law.

         (c) Subject to the provisions of Section 6.07 of this Agreement, the
By-Laws of the Purchaser in effect at the Effective Time shall be the By-Laws of
the Surviving Corporation until amended in accordance with the provisions
thereof and applicable law.

         (d) Subject to applicable law, the directors of the Purchaser
immediately prior to the Effective Time shall be the initial directors of the
Surviving Corporation and shall hold office until their respective successors
are duly elected and qualified, or their earlier death, resignation or removal.

         (e) The officers of the Company immediately prior to the Effective 
Time shall be the initial officers of the Surviving Corporation and shall 
hold office until their respective successors are duly elected and qualified, 
or their earlier death, resignation or removal.

         SECTION 2.04 Additional Actions. If, at any time after the Effective
Time, the Surviving Corporation shall consider or be advised that any further
deeds, assignments or assurances in law or any other acts are necessary or
desirable to (a) vest, perfect or confirm, of record or otherwise, in the
Surviving Corporation its rights, title or interest in, to or under any of the
rights, properties or assets of the Company or its Subsidiaries, or (b)
otherwise carry out the provisions of this Agreement, the Company and its
officers and directors shall be deemed to have granted the Surviving Corporation
an irrevocable power of attorney to execute and deliver all such deeds,
assignments or assurances in law and to take all acts necessary, proper or
desirable to vest, perfect or confirm title to and possession of such rights,
properties or assets in the Surviving Corporation and otherwise to carry out the
provisions of this Agreement, and the officers and directors of the Surviving
Corporation are authorized in the name of the Company or otherwise to take any
and all such action.

         SECTION 2.05 Conversion of Common Shares. At the Effective Time, by
virtue of the Merger and without any action on the part of the holders thereof,
(I) each Common Share issued and outstanding immediately prior to the Effective
Time (other than Dissenting Shares (as defined in Section 3.01) and Shares held
by the Company, Parent, Purchaser and their respective Subsidiaries) shall be
converted into the right to receive the Merger Consideration in cash, payable to
the holder thereof, without interest thereon, upon surrender of the certificate

<PAGE>


formerly representing such Common Share, and (ii) each Common Share owned by the
Company or one of its Subsidiaries or by Parent or Purchaser or one of its
Subsidiaries shall be canceled without payment and without surrender of the
certificate formerly representing such Common Shares.


         SECTION 2.06 Conversion of Purchaser Common Stock. At the Effective
Time, each share of common stock, par value $.01 per share, of the Purchaser
issued and outstanding immediately prior to the Effective Time shall, by virtue
of the Merger and without any action on the part of the holder thereof, be
converted into and become one validly issued, fully paid and non-assessable
share of common stock, par value $.01 per share, of the Surviving Corporation.

         SECTION 2.07 Company Option Plans. At the Effective Time, by virtue of
the Merger and without any action on the parts of the holders thereof, each then
outstanding Option shall be converted into the right to receive an amount
determined by multiplying (i) the excess, if any, of the Offer Price over the
applicable exercise price of such Option by (ii) the number of Common Shares
such holder could have purchased if such holder had exercised such Option
immediately prior to the Effective Time, but only to the extent then vested and
exercisable, provided that the determination of the exercisability of Options
shall take into account the acceleration of vesting provided for in the Option
Plan or the SBS Plan. The Surviving Corporation will pay any amount required to
be paid pursuant to this Section 2.07 upon exercise or delivery of any then
outstanding Options to the Surviving Corporation by or on behalf of the holder
thereof.

         SECTION 2.08 Merger Without Meeting of Stockholders. The Purchaser and
Parent agree to take all necessary and appropriate action to cause the Merger to
become effective as soon as practicable after the acceptance for payment of and
payment for Common Shares by the Purchaser pursuant to the Offer without a
meeting of stockholders of the Company, in accordance with Section 253 of the
GCL.

                                   ARTICLE III

                      DISSENTING SHARES; PAYMENT FOR SHARES

         SECTION 3.01 Dissenting Shares. Notwithstanding anything in this
Agreement to the contrary, Common Shares outstanding immediately prior to the
Effective Time and held by a holder who has demanded appraisal for such Shares
in accordance with Section 262 of the GCL, if such Section 262 provides for
appraisal rights for such shares in the Merger ("Dissenting Shares"), shall not
be converted into the right to receive the Merger Consideration as provided in
Section 2.05, unless and until such holder fails to perfect or withdraws or
otherwise loses his right to appraisal and payment under the GCL. If, after the
Effective Time, any such holder fails to perfect or withdraws or loses his right
to appraisal, such Dissenting

<PAGE>

Shares shall thereupon be treated as if they had been converted as of the
Effective Time into the right to receive the Merger Consideration, if any, to
which such holder is entitled, without interest or dividends thereon. The
Company shall give Parent prompt notice of any demands received by the Company
for appraisal of Common Shares and Parent shall have the right to participate in
all negotiations and proceedings with respect to such demands. Prior to the
Effective Time, the Company shall not, except with the prior written consent of
Parent, make any payment with respect to, or settle or offer to settle, any such
demands.



         SECTION 3.02 Payment for Common Shares.

         (a) From and after the Effective Time, The Bank of New York, or such
other bank or trust company as shall be mutually acceptable to Parent and the
Company, shall act as paying agent (the "Paying Agent") in effecting the payment
of the Merger Consideration in respect of certificates (the "Certificates")
that, prior to the Effective Time, represented Common Shares entitled to payment
of the Merger Consideration pursuant to Section 2.05. At the Effective Time,
Parent or the Purchaser shall deposit, or cause to be deposited, in trust with
the Paying Agent the aggregate Merger Consideration to which holders of Common
Shares shall be entitled at the Effective Time pursuant to Section 2.05.

         (b) Promptly after the Effective Time, the Paying Agent shall mail to
each record holder of Certificates that immediately prior to the Effective Time
represented Common Shares (other than Certificates representing Dissenting
Shares and Certificates representing Common Shares held by Parent, the
Purchaser, or the Company) a form of 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 instructions for use in surrendering such certificates and receiving the
Merger Consideration in respect thereof. Upon the surrender of each such
Certificate, the Paying Agent shall, in consideration for the shares represented
by such Certificates, pay the holder of such Certificate the Merger
Consideration multiplied by the number of Common Shares formerly represented by
such Certificate, in consideration therefor, and such Certificate shall
forthwith be canceled. Until so surrendered, each such Certificate (other than
Certificates representing Dissenting Shares and Certificates representing Common
Shares held by Parent, the Purchaser, or the Company) shall represent solely the
right to receive the aggregate Merger Consideration relating thereto. No
interest or dividends shall be paid or accrued on the Merger Consideration. If
the Merger Consideration (or any portion thereof) is to be delivered to any
person other than the person in whose name the Certificate formerly representing
Common Shares surrendered therefor is registered, it shall be a condition to
such right to receive such Merger Consideration that the Certificate so
surrendered shall be properly endorsed or otherwise be in proper form for
transfer and that the person surrendering such Common Shares shall pay to the
Paying Agent any transfer or other taxes required by reason of the payment of
the Merger Consideration to a person other than the registered holder of the
Certificate surrendered, or shall establish to the satisfaction of the Paying
Agent that such tax has been paid or is not applicable. Promptly after the
Effective Time, the Paying Agent shall mail to each record holder of
Certificates that immediately prior to the Effective Time represented Dissenting
Shares a notice of appraisal rights.

<PAGE>

         (c) Promptly following the date which is 180 days after the Effective
Time, the Paying Agent shall deliver to the Surviving Corporation all cash,
Certificates and other documents in its possession relating to the transactions
described in this Agreement, and the Paying Agent's duties shall terminate.
Thereafter, holders of Common Shares who have not theretofore complied with this
Section 3.02 shall look only to the Surviving Corporation for payment of the
Merger Consideration in respect thereof (subject to applicable abandoned
property, escheat and similar laws), in each case, without interest or dividends
thereon.

         (d) None of Parent, the Purchaser, the Surviving Corporation or the
Paying Agent shall be liable to any person in respect of any Common Shares (or
dividends or distributions with respect thereto) or cash deposited by Parent or
the Purchaser with the Paying Agent that is 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 seven years after the
Effective Time (or immediately prior to such earlier date on which any cash
would otherwise escheat to or become the property of any Governmental Entity),
any such cash 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.

         (e) Parent, the Purchaser and the Paying Agent shall be entitled to
deduct and withhold from the consideration otherwise payable or issuable
pursuant to this Agreement to any holder of Common Shares such amounts as
Parent, the Purchaser or the Paying Agent are required to deduct and withhold
with respect to such payment or issuance under the Code, or any provision of
state, local or foreign tax law. To the extent that amounts are so withheld,
such withheld amounts shall be treated for all purposes of this Agreement as
having been paid to the holders of Common Shares in respect of which such
deduction and withholding was made.

         (f) All cash issued upon surrender of Certificates in accordance with
the terms hereof shall be deemed to have been issued in full satisfaction of all
rights pertaining to such Common Shares formerly represented thereby. After the
Effective Time, there shall be no transfers on the stock transfer books of the
Surviving Corporation of any Common Shares which were outstanding immediately
prior to the Effective Time. If, after the Effective Time, Certificates formerly
representing Common Shares are presented to the Surviving Corporation or the
Paying Agent, they shall be surrendered and canceled in return for the payment
of the aggregate Merger Consideration relating thereto, as provided in this
Article III, subject to applicable law in the case of Dissenting Shares.

                                   ARTICLE IV

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         The Company represents and warrants to Parent and the Purchaser that
except as set forth in the Disclosure Schedules (as hereinafter defined) as of
the date hereof (or such other later date as is specified):

         SECTION 4.01 Organization and Qualification; Subsidiaries. (a) The

<PAGE>


Company is a corporation duly organized, validly existing and in good standing
under the laws of the State of Delaware. Set forth on the Subsidiary Schedule is
a list of every corporation, limited liability company, partnership or other
business organization or entity of which the Company owns, either directly or
through its Subsidiaries, (a) more than 50% of (i) the total combined voting
power of all classes of voting securities of such entity, (ii) the total
combined equity interests therein, or (iii) the capital or profit interests
therein, in the case of a partnership; or (b) otherwise has the power to vote or
direct the voting of sufficient securities to elect a majority of the board of
directors or similar governing body of such entity (the "Subsidiaries"). Each of
the Subsidiaries listed on the Subsidiary Schedule is a corporation duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation. The Company and each of the Subsidiaries has
the requisite corporate power to own, operate or lease its properties and to
carry on its business as it is now being conducted, and is duly qualified or
licensed to do business, and is in good standing, in each jurisdiction in which
the nature of its business or the properties owned, operated or leased by it
makes such qualification, licensing or good standing necessary, except where the
failure to have such power, or the failure to be so qualified, licensed or in
good standing, would not have a Material Adverse Effect on the Company. The term
"Material Adverse Effect on the Company," as used in this Agreement, means any
development, condition or circumstance having an effect on the assets, business,
operations, or financial condition of the Company or any of its Subsidiaries
that is materially adverse to the Company and its Subsidiaries taken as a whole
other than any development, condition or circumstance resulting from general
economic conditions or relating generally to the coal or electric power
industries.

         SECTION 4.02 Charter and By-Laws. The Company has heretofore made
available to Parent and the Purchaser a complete and correct copy of the charter
and the by-laws or comparable organizational documents, each as amended to the
date hereof, of the Company and each of the Subsidiaries.

         SECTION 4.03 Capitalization. The authorized capital stock of the
Company consists of 50,000,000 Common Shares and 1,000,000 shares of Preferred
Stock, no par value. As of the close of business on July 28, 1998, 28,222,671
Common Shares were issued and outstanding, and 244,000 Common Shares were in the
Company's treasury, and no shares of Preferred Stock were issued and
outstanding. The Company has no shares reserved for issuance, except that, as of
July 28, 1998, there were 1,666,760 Common Shares reserved for issuance pursuant
to outstanding Options under the Option Plan, all of which were granted prior to
March 31, 1998. The Options Schedule sets forth the name of each holder of an
outstanding Option under the Option Plan, and with respect to each Option held
by any such holder, the grant date, exercise price and number of Common Shares
for which such Option is exercisable. As of the date hereof, the Company has no
options to purchase Common Shares outstanding other than those granted and
outstanding under the Option Plan. Since December 31, 1997, the Company has not
issued any shares of capital stock except pursuant to the exercise of Options
outstanding as of such date. All of the outstanding Common Shares are, and all
Common Shares which may be issued pursuant to the exercise of outstanding
Options will be, when issued in accordance with the respective terms thereof,
duly authorized, validly issued, fully paid and nonassessable. There 


<PAGE>

are no bonds, debentures, notes or other indebtedness having general voting
rights (or convertible into securities having such rights) of the Company or any
of its Subsidiaries issued and outstanding. Except as set forth on the Options
Schedule and except as contemplated by this Agreement, or between the Company
and one or more of its direct or indirect wholly-owned subsidiaries, there are
no existing options, warrants, calls, subscriptions or other rights, agreements,
arrangements or commitments of any character, relating to the issued or unissued
capital stock of the Company or any of the Subsidiaries, obligating the Company
or any of the Subsidiaries to issue, transfer or sell or cause to be issued,
transferred or sold any shares of capital stock of, or other equity interest in
or voting security of, the Company or any of the Subsidiaries or securities
convertible into or exchangeable for such shares or equity interests or voting
securities and neither the Company nor any of the Subsidiaries is obligated to
grant or enter into any such option, warrant, call, subscription or other right,
agreement, arrangement or commitment. Except as contemplated by this Agreement
or between the Company and one or more of its direct or indirect wholly-owned
subsidiaries, there are no outstanding contractual obligations of the Company or
any of its Subsidiaries to repurchase, redeem or otherwise acquire any Common
Shares or the capital stock of the Company or any of the Subsidiaries. Each of
the outstanding shares of capital stock of each of the Company's Subsidiaries is
duly authorized, validly issued, fully paid and nonassessable, and such shares
of the Company's Subsidiaries as are owned by the Company or by a subsidiary of
the Company are owned in each case free and clear of any Lien (as hereinafter
defined). Other than as set forth on the Contracts Schedule, the Company has not
agreed to register any securities under the Securities Act or under any state
securities law or granted registration rights to any person or entity.

         SECTION 4.04 Authority Relative to this Agreement. The Company has all
necessary corporate power and authority to execute and deliver this Agreement
and to consummate the transactions contemplated hereby. The execution and
delivery of this Agreement by the Company and the consummation by the Company of
the transactions contemplated hereby have been duly and validly authorized and
approved by the Board and no other corporate proceedings on the part of the
Company or on the part of the stockholders of the Company are necessary to
authorize or approve this Agreement or to consummate the transactions
contemplated hereby except as required by Delaware law. This Agreement has been
duly and validly executed and delivered by the Company and, assuming the due and
valid authorization, execution and delivery of this Agreement by Parent and the

Knowledge, any of its directors, officers, employees or any other "fiduciary,"
as such term is defined in Section 3 of ERISA, has committed any material breach

respect to the Plans which would subject Parent or Purchaser or any of their
respective directors, officers or employees to any material liability under
ERISA or any applicable law.

         (e) The Company has not incurred any material liability for any tax or
civil penalty imposed by Section 4975 of the Code or Section 502 of ERISA.

ERISA, (ii) under section 302 of ERISA, (iii) under sections 412 and 4971 of the
Code, (iv) as a result of a failure to comply with the continuation coverage
requirements of section 601 et seq. of ERISA and section 4980B of the Code, (v)
under Section 701, et seq. of ERISA, or (vi) under corresponding or similar
provisions of foreign laws or regulations that would be a liability of the
Company following the Effective Time, other than such liabilities under the

Subsidiaries and will cause the Company Representatives to furnish Parent, the
Purchaser and the Parent Representatives to the extent available with such
financial and operating data and such other information with respect to the
business and operations of the Company and its Subsidiaries 

<PAGE>

as Parent and the Purchaser may from time to time reasonably request; provided
that if the Company determines in good faith that any such data or information
is competitively sensitive, Parent and the Company will reasonably agree to
appropriate limitations on the dissemination of such information within the
Purchaser's and Parent's respective organizations. Prior to the Offer Purchase
Closing, neither Parent or Purchaser nor the Parent Representatives shall
contact or in any manner communicate with the employees, customers, lessors and
suppliers of the Company and its Subsidiaries with respect to any matter related
to the transactions contemplated hereby, except with the prior consent of the
Company.

         SECTION 6.03 Reasonable Efforts Notice of Certain Developments.

         (a) Subject to the terms and conditions herein provided and to
applicable legal requirements, each of the parties hereto agrees to use
reasonable efforts to take, or cause to be taken, all action, and to do, or
cause to be done (in the case of the Company consistent with the fiduciary
duties of the Company's Board of Directors under applicable law), and to assist
and cooperate with the other parties hereto in doing, as promptly as
practicable, all things necessary, proper or advisable under applicable laws and
regulations to ensure that the conditions set forth in Article VII are satisfied
and to consummate and make effective the transactions contemplated by the Offer,
the Merger and this Agreement.

         (b) If at any time prior to the Effective Time any event or
circumstance relating to either the Company or Parent or the Purchaser or any of
their respective Subsidiaries, is discovered by the Company or Parent, as the
case may be, which should be set forth in an amendment to the Offer Documents or
Schedule 14D-9, the discovering party will promptly inform the other party of
such event or circumstance. If at any time after the Effective Time any further
action is necessary or desirable to carry out the purposes of this Agreement,
including the execution of additional instruments, the proper officers and
directors of each party to this Agreement shall take all such necessary action.

         (c) Parent and Purchaser covenant and agree to do all other things
reasonably necessary to obtain the financing necessary for fulfillment of the
Offer Financing Condition (whether from the issuers of the Commitment Letters or
from other sources), on terms and conditions that are not less favorable in the
aggregate to Parent and Purchaser than those contemplated by the Commitment
Letters.

         (d) Parent and Purchaser further covenant and agree that they will not,
at any time prior to the termination of this Agreement, terminate or modify,
amend or alter the obligations of the issuer of the Commitment Letter in any way
that would be materially adverse to the Parent's or Purchaser's ability to cause
the Offer Financing Condition to be satisfied.

         SECTION 6.04 Consents.

         (a) Each party hereby agrees to use its reasonable best efforts to file
the premerger notification report, and all other documents to be filed in
connection therewith, required by the HSR Act and the Premerger Notification
Rules promulgated thereunder 

<PAGE>


with the United States Federal Trade Commission ("FTC") and the United States
Department of Justice ("DOJ") as soon as practicable following the date hereof,
but in any event (i) with respect to Parent and Purchaser, within five days
following the date hereof and (ii) with respect to the Company, within ten days
following the date hereof. Each party shall respond promptly to any request for
additional information that may be issued by either FTC or DOJ and shall use
commercially reasonable efforts to assure that the waiting period required by
the HSR Act has expired or been terminated prior to the date that is 20 days
following the commencement of the Offer.

         (b) Each of the parties will use commercially reasonable efforts to
obtain as promptly as practicable all Consents of any Governmental Entity or any
other person required in connection with, and waivers of any Violations that may
be caused by, the consummation of the transactions contemplated by the this
Agreement.

         (c) In furtherance and not in limitation of the foregoing, Parent shall
use commercially reasonable best efforts to resolve such objections, if any, as
may be asserted with respect to the transactions contemplated by this Agreement
under any antitrust, competition or trade regulatory laws, rules or regulations
of any domestic or foreign government or governmental authority or any
multinational authority ("Antitrust Laws"). If any suit is instituted
challenging any of the transactions contemplated by this Agreement as violative
of any Antitrust Law, Parent shall take such action (including without
limitation, agreeing to hold separate or to divest any of the businesses,
product lines or assets of Parent or any of its affiliates or of any of the
Company, its Subsidiaries or affiliates (a "Business Unit") (but only if the
Business Units required to be held separate or divested do not in the aggregate
have a fair market value of more than $25,000,000 or revenues for the most
recently completed 12 months of more than $25,000,000) as may be required (a) by
the applicable government or governmental or multinational authority (including,
without limitation, the Antitrust Division of the United States Department of
Justice, the Federal Trade Commission or the European Economic Area) in order to
resolve such objections as such government or authority may have to such
transactions under such Antitrust Law, or (b) by any domestic or foreign court
or similar tribunal, in any suit brought by a private party or governmental or
multinational authority challenging the transactions contemplated by this
Agreement as violative of any Antitrust Law, in order to avoid the entry of, or
to effect the dissolution of, any injunction, temporary restraining order or
other order that has the effect of preventing the consummation of any of such
transactions. The entry by a court, in any suit brought by a private party or
governmental or multinational authority challenging the transactions
contemplated by this Agreement as violative of any Antitrust Law, of an order or
decree permitting the transactions contemplated by this Agreement, but requiring
that any Business Units of any of Parent or its affiliates, the Company or its
Subsidiaries or affiliates be divested or held separate by Parent (but only if
such Business Units required to be held separate or divested do not in the
aggregate have a fair market value of more than $25,000,000 or revenues for the
most recently completed 12 months of more than $25,000,000), or that would
otherwise limit Parent's freedom of action with respect to, or its ability to
retain, the Company and its Subsidiaries or any portion thereof or any of
Parent's or its affiliates' other assets or businesses, shall not be deemed a
failure to satisfy the conditions specified in Annex I

<PAGE>

or Section 7.01(b) hereof.

         (d) Any party hereto shall promptly inform the others of any material
communication from the United States Federal Trade Commission, the Department of
Justice or any other domestic or foreign government or governmental or
multinational authority regarding any of the transactions contemplated by this
Agreement. If any party or any affiliate thereof receives a request for
additional information or documentary material from any such government or
authority with respect to the transactions contemplated by this Agreement, then
such party will endeavor in good faith to make, or cause to be made, as soon as
reasonably practicable and after consultation with the other party, an
appropriate response in compliance with such request. Parent will advise the
Company promptly in respect of any understandings, undertakings or agreements
(oral or written) which Parent proposes to make or enter into with the Federal
Trade Commission, the Department of Justice, or any other domestic or foreign
government or governmental or multinational authority in connection with the
transactions contemplated by this Agreement.

         SECTION 6.05 Public Announcements. Prior to the Closing, except as
required by applicable law or by any rule or regulation of the New York Stock
Exchange, no party hereto shall issue any press release or otherwise make any
public statement with respect to this Agreement and the transactions
contemplated hereby without the prior written consent of the other parties
hereto. With respect to any public statement of either party that does not
require the consent of the other party, the party making such statement shall,
prior to public disclosure thereof, first consult with and provide the other
party a reasonable opportunity to review the contents of such statement.

         SECTION 6.06 Employee Benefit Arrangements. Parent shall cause the
Company to honor all accrued obligations as of the date hereof under the
employee arrangements (the "Employee Arrangements") to which the Company or any
of its Subsidiaries is presently a party which are listed in the Employee
Arrangements Schedule and the Developments Schedule in accordance with the terms
and conditions of such arrangements. In addition, from and after the Closing
until the first anniversary of the Closing, subject to the remaining provisions
of this Section 6.06, the Surviving Corporation shall not amend, modify, alter
or terminate any severance or change of control agreements, policies or
practices of the Company or its Subsidiaries, including the SBS Plan; provided
that any such action after the first anniversary of the Closing shall not
adversely affect the accrued or vested rights of any employees or other
beneficiaries which shall have arisen under any severance or change of control
agreements, policies or practices of the Company or its Subsidiaries, including
the SBS Plan prior to such amendment, modification, alteration or termination.
Parent shall cause the Company for a period of one year following the Effective
Time, to continue to provide to employees of the Company and its Subsidiaries
who are employed by the Surviving Corporation (excluding employees covered by
collective bargaining agreements) broad-based employee benefit plans and
Employee Arrangements which are in the aggregate no less favorable than those
provided to such 

<PAGE>

employees as of the date hereof provided that it is understood that the
Surviving Corporation may alter, amend, modify and/or terminate specific benefit
plans and/or arrangements (including Employee Arrangements) subject to the
aggregate limitations set forth above. Subject to the foregoing, nothing in this
Section shall be deemed to limit or otherwise affect the right of the Surviving
Corporation to terminate employment or change the place of work,
responsibilities, status or designation of any employee or group of employees as
the Surviving Corporation may determine in the exercise of its business judgment
and in compliance with applicable laws. Solely for purposes of eligibility and
vesting under Employee Arrangements (including without limitation plans or
programs of Parent and its affiliates after the Effective Time), and to the
extent permitted by law, all service with the Company or any of its Subsidiaries
or their predecessors prior to the Effective Time shall be treated as service
with Parent and its affiliates (to the extent such service was recognized by the
Company or any of its Subsidiaries for similar purposes under comparable plans
before the Effective Time).


         SECTION 6.07 Indemnification.

         (a) Parent agrees that all rights to indemnification now existing in
favor of any director or officer of the Company and its Subsidiaries (the
"Indemnified Parties") as provided in their respective charters or by-laws or,
in an agreement between an Indemnified Party and the Company or one of its
Subsidiaries, shall survive the Merger and shall continue in full force and
effect for a period of not less than six years from the Effective Time; provided
that in the event any claim or claims are asserted or made within such six-year
period, all rights to indemnification in respect of any such claim or claims
shall continue until final disposition of any and all such claims. Parent agrees
to cause the Surviving Corporation to honor all rights to indemnification
referred to in the preceding sentence. Without limitation of the foregoing, in
the event any such Indemnified Party is or becomes involved in any capacity in
any action, proceeding or investigation in connection with any matter,
including, without limitation, the transactions contemplated by this Agreement,
occurring prior to, and including, the Effective Time, Parent will cause to be
paid in accordance with the applicable charters, by-laws and agreements, as
incurred such Indemnified Party's legal and other expenses (including the cost
of any investigation and preparation) incurred in connection therewith. The
Surviving Corporation shall pay all reasonable expenses, including attorneys'
fees, that may be incurred by any Indemnified Party in enforcing the indemnity
and other obligations provided for in this Section 6.07 subject to the
limitations of the GCL to the extent applicable.

         (b) Parent agrees that the Company, and from and after the Effective
Time, the Surviving Corporation shall cause to be maintained in effect for not
less than six years from the Effective Time for the benefit of all current and
former directors and officers of the Company the current policies of the
directors' and officers' liability insurance maintained by the Company; provided
that the Surviving Corporation may substitute therefor other policies not less
advantageous (other than to a de minimus extent) to the beneficiaries of the
current policies and provided that such substitution shall not result in any
gaps or lapses in coverage with respect to matters occurring prior to the
Effective Time; and provided, further, that the Surviving Corporation shall not
be required to pay an annual premium in excess of 300% of the last annual


<PAGE>

premium paid by the Company prior to the date hereof which is set forth in the
Insurance Schedule and if the Surviving Corporation is unable to obtain the
insurance required by this Section 6.07(b) it shall obtain as much comparable
insurance as possible for an annual premium equal to such maximum amount.

         SECTION 6.08 Notification of Certain Matters. Parent and the Company
shall promptly notify each other of (a) (i) it becoming aware of any fact or
event which would be reasonably likely to demonstrate that any representation or
warranty of any party hereto contained in this Agreement was or is untrue or
inaccurate in any material respect as of the date of this Agreement or (ii) the
occurrence or non-occurrence of any fact or event which would be reasonably
likely to cause any material covenant, condition or agreement of any party
hereto under this Agreement not to be complied with or satisfied in all material
respects and (b) any failure of any party hereto to comply with or satisfy any
covenant, condition or agreement to be complied with or satisfied by it
hereunder in any material respect; provided, however, that no such notification
shall affect the representations or warranties of any party or the conditions to
the obligations of any party hereunder.


         SECTION 6.09 No Solicitation; Termination Right.

         (a) The Company agrees that, during the term of this Agreement it shall
not, and shall not authorize, support or encourage any of its Subsidiaries or
any of its or its Subsidiaries' directors, officers, employees, agents or
representatives, directly or indirectly, to solicit, initiate, encourage,
facilitate or furnish or disclose non-public information in furtherance of, any
inquiries or the making of any proposal with respect to any recapitalization,
merger, consolidation or other business combination involving the Company, or
acquisition of any capital stock (other than upon exercise of the Options which
are outstanding as of the date hereof) or any portion of the assets (except for
acquisition of assets in the ordinary course of business consistent with past
practice) of the Company and its Subsidiaries, or any combination of the
foregoing (a "Competing Transaction"), or negotiate, or otherwise engage in
discussions with any person (other than Parent, the Purchaser or their
respective directors, officers, employees, agents and representatives) for the
purpose of facilitating any Competing Transaction or enter into any agreement,
arrangement or understanding requiring it to abandon, terminate or fail to
consummate the Merger or any other transactions contemplated by this Agreement;
provided that the Company shall use its reasonable best efforts to ensure that
none of its Subsidiaries and none of its or its Subsidiaries' directors,
officers, employees, agents or representatives, directly or indirectly,
undertakes any such actions, and, if the Board learns of any such action, the
Company shall take reasonable steps to cause the party undertaking such action
to cease such action immediately or shall immediately terminate the Company's
and/or any Subsidiary's employment or other relationship with any such director,
officer, employee, agent or representative that breaches this Section 6.09;
provided further that prior to the purchase of the Common Shares by the
Purchaser pursuant to the Offer, the Company may furnish information to, and
negotiate or otherwise engage in discussions with, any party who makes a bona
fide proposal regarding a Competing Transaction which was not solicited by the
Company after the date of this Agreement and which does not violate any
Standstill Agreement if and so long as the 

<PAGE>

Board after consultation with its counsel determines in good faith that failing
to consider and cooperate with such other party regarding such Competing
Transaction would constitute a breach of the fiduciary duties of the Board to
the Company's stockholders under applicable law, and, provided further, that in
no event does the term "Competing Transaction" include a sale or other
disposition of any of the assets specified on the Non-Coal Asset Schedule or
that is otherwise specifically permitted hereunder. The Company shall and shall
use its reasonable best efforts to cause its Subsidiaries, directors, officers,
employees, agents and representatives immediately to cease all existing
activities, discussions and negotiations with any parties conducted heretofore
with respect to any Competing Transaction. The Company agrees that neither the
Board of Directors nor any committee thereof will, during the period referenced
in the first sentence of this subsection (a), (A) withdraw or modify, or propose
publicly to withdraw or modify, in a manner adverse to Parent or the Purchase,
the Board Recommendation, or (B) approve or recommend, or propose publicly to
approve or recommend, any Competing Transaction. The foregoing notwithstanding,
in the event that prior to the purchase of Common Shares by the Purchaser
pursuant to the Offer the Board of Directors after consultation with its counsel
determines in good faith that failure to do so will result in breach of the
fiduciary duties of the Board to the Company's stockholders under applicable
law, the Board of Directors may (subject to this and the following sentences)
withdraw or modify the Board Recommendation, provided that it gives Parent three
days' prior written notice of its intention to do so. Any such withdrawal or
modification of the Board Recommendation shall not change the approval of the
Board of Directors for purposes of causing any state takeover statute or other
state law to be inapplicable to the transactions contemplated hereby, including
the Offer, the Merger or the Tender Commitments. The Company shall immediately
advise Parent in writing of the receipt, directly or indirectly, of any
inquiries, discussions, negotiations, or proposals relating to a Competing
Transaction, which becomes known to the Board during the term of this Agreement.
The Company shall keep Parent fully apprised of the status and terms of any
proposal relating to a Competing Transaction on a current basis.

         (b) If, prior to the purchase of Common Shares by the Purchaser
pursuant to the Offer, the Board after consultation with its financial and legal
advisors determines in good faith that any written proposal from a third party
for a Competing Transaction received after the date hereof that was not
solicited by the Company or any of its Subsidiaries or affiliates in violation
of this Agreement (and that does not violate or breach any Standstill Agreement
executed by such party with respect to the Company prior to the date of this
Agreement) is more favorable to the stockholders of the Company from a financial
point of view than the transactions contemplated by this Agreement (including
any adjustment to the terms and conditions of such transaction proposed in
writing by the Company in response to such Competing Transaction) and is in the
best interest of the stockholders of the Company, the Company may terminate this
Agreement at any time prior to the Offer Purchase Closing and enter into a
letter of intent, agreement-in-principle, acquisition agreement or other similar
agreement (each, an "Acquisition Agreement") with respect to such Competing
Transaction provided that, the Company provides written notice of such
termination to Parent at least three full business days prior to the


<PAGE>

effectiveness of such termination and, the Company delivers to Parent within
five business days following such termination (A) by check or wire transfer of
same day funds, (i) an amount equal to Parent's Costs (as defined in Section
8.02) as the same may have been estimated by Parent in good faith prior to the
date of such delivery (subject to an adjustment payment between the parties upon
Parent's definitive determination of such costs), but in any event not to exceed
$10,000,000, and (ii) the amount of the Termination Fee as provided in Section
8.02 and (B) a written acknowledgment from the Company and the other party to
the Competing Transaction that the Company and such other party have irrevocably
waived any right to contest such payments.

         SECTION 6.10 Cooperation for Financing. The Company agrees that, during
the term of this Agreement, it shall provide reasonable cooperation to the
Purchaser to facilitate the Purchaser's efforts to obtain the financing
contemplated by the Commitment Letters (including assisting the Purchaser in
obtaining required consents) and provide all information reasonably requested by
the Purchaser in connection with the Purchaser's efforts to satisfy the Offer
Financing Condition.

         SECTION 6.11 Tender Commitments. The Company shall cause each of the
Stockholders to execute a Tender Commitment. The Company shall not permit the
amendment, modification, release under or otherwise lessen the obligations of
the Stockholders under the Tender Commitments. The Company agrees to enforce
fully and promptly all provisions of the Tender Commitments, including, without
limitation, seeking specific performance of (or other equitable and legal
remedies with respect to) each Stockholder's obligations under its Tender
Commitment.


                                   ARTICLE VII

                    CONDITIONS TO CONSUMMATION OF THE MERGER

         SECTION 7.01 Conditions. The respective obligations of Parent, the
Purchaser and the Company to consummate the Merger are subject to the
satisfaction, at or before the Effective Time, of each of the following
conditions:

         (a) Purchase of Common Shares. The Purchaser shall have accepted for
payment and paid for Common Shares pursuant to the Offer in accordance with the
terms hereof; provided that this condition shall be deemed to have been
satisfied with respect to Parent and the Purchaser if the Purchaser fails to
accept for payment or pay for Common Shares pursuant to the Offer in violation
of the terms of the Offer.

         (b) No Injunctions or Restraints; Illegality. No (i) order or
preliminary or permanent injunction shall be entered in any action or proceeding
before any court of competent jurisdiction or any statute, rule, regulation,
legislation, or order shall be enacted, entered, enforced, promulgated, amended
or issued by any United States legislative body, court, government or
governmental, administrative or regulatory authority or agency (other than the
waiting period provisions of the HSR Act) which shall remain in effect and which
shall have the 

<PAGE>

effect of (x) making illegal or restraining or prohibiting the making of the
Offer, the acceptance for payment of, or payment for, the Common Shares by
Parent, the Purchaser or any other affiliate of Parent, or the consummation of
the Offer or the Merger or (y) imposing material limitations on the ability of
the Purchaser effectively to acquire or hold or exercise full rights of
ownership of the Common Shares, including, without limitation, the right to vote
the Common Shares purchased by the Purchaser on all matters properly presented
to the stockholders of the Company; provided, that Parent, to the extent
provided in this Agreement, shall, if necessary to prevent the taking of such
action, or the enactment, enforcement, promulgation, amendment, issuance or
application of any statute, rule, regulation, legislation, judgment, order or
injunction, offer to accept an order to divest such of the Company's or Parent's
assets and businesses as may be necessary to forestall such injunction or order
and to hold separate such assets and business pending such divestiture; (ii)
proceeding brought by an administrative agency or commission or other domestic
Governmental Entity seeking any of the foregoing shall be pending; or (iii)
action or proceeding shall be commenced following the date of this Agreement and
be pending before any court of competent jurisdiction which would have a
Material Adverse Effect on the Company.

                                  ARTICLE VIII

                         TERMINATION; AMENDMENTS; WAIVER

         SECTION 8.01 Termination. This Agreement may be terminated and the
Merger contemplated hereby may be abandoned at any time prior to the Effective
Time, notwithstanding approval thereof by the stockholders of the Company (with
any termination by Parent also being an effective termination by the Purchaser):


         (a) By the mutual written consent of Parent and the Company;

         (b) By the Company if (i) the Purchaser fails to commence the Offer as
provided in Section 1.01 hereof or, (ii) the Purchaser fails to purchase validly
tendered Common Shares in violation of the terms of the Offer or this Agreement;

         (c) By Parent or the Company if the Offer is terminated or withdrawn
pursuant to its terms without any Common Shares being purchased thereunder;
provided, however, that neither Parent nor the Company may terminate this
Agreement pursuant to this Section 8.01(c) if such party shall have materially
breached this Agreement or, in the case of Parent, if it or the Purchaser is in
material violation of the terms of the Offer.

         (d) By Parent or the Company if any court or other Governmental Entity
shall have issued, enacted, entered, promulgated or enforced any order,
judgment, decree, injunction, or ruling or taken any other action restraining,
enjoining or otherwise prohibiting the Merger and such order, judgment, decree,
injunction, ruling or other action shall have become final and nonappealable;
provided that the party seeking to terminate the Agreement shall have used its

<PAGE>

reasonable efforts to remove or lift such order, decree or ruling;

         (e) By Parent or the Company if the Offer Financing Conditions shall be
impossible to satisfy by the end of the twentieth (20th) business day following
commencement of the Offer and by the Parent or the Company if any other
condition set forth in Annex I attached hereto shall be impossible to satisfy by
the end of the thirtieth (30th) business day following commencement of the Offer
unless such circumstance results from the failure of the terminating party to
perform in any material respect its obligations under this Agreement, provided,
however, that the Company may not terminate this Agreement pursuant to this
Section 8.01(e) if Parent waives in writing the relevant condition (other than
the Minimum Condition as defined in Annex I, which cannot be waived);

         (f) By Parent if prior to the Offer Purchase Closing the Board shall
have withdrawn or modified in a manner adverse to Parent, or refrained from
making the Board Recommendation, or shall have publicly disclosed its intention
to change such recommendation, or shall have failed to reaffirm the Board
Recommendation within five (5) days of receipt from Parent or the Purchaser of a
request to so reaffirm the Board Recommendation, in each case except due to
Parent or Purchaser's material breach of this Agreement or material violation of
the terms of the Offer;

         (g) By the Company, pursuant to and in accordance with Section 6.09(b);

         (h) By the Company in the event of any breach of the covenants and/or
representations and warranties of Parent and Purchaser contained in this
Agreement which has a material adverse effect on the consummation of the
transactions contemplated by this Agreement; or

         (i) By Parent, if any Stockholder who holds more than five percent of
the Shares shall have breached any of his, her or its obligations under the
Tender Commitment.

         SECTION 8.02 Effect of Termination; Fees and Expenses.

         (a) In the event of the termination of this Agreement pursuant to
Section 8.01, this Agreement shall forthwith become void and have no effect,
without any liability on the part of any party or its directors, officers or
stockholders, other than the provisions of this Section 8.02 and the
confidentiality provisions referenced in the first sentence of Section 6.02,
which shall survive any such termination. Nothing contained in this Section 8.02
shall relieve any party from liability for any breach of this Agreement or the
Confidentiality Agreement, and provided, further, however, that if it shall be
judicially determined that termination of this Agreement was caused by an
intentional breach of this Agreement, then, in addition to other remedies at law
or equity for breach of this Agreement, the party so found to have intentionally
breached this Agreement shall indemnify and hold harmless the other parties for
their respective costs, fees and expenses of their counsel, accountants,
financial advisors and other experts and advisors as well as fees and expenses
incident to negotiation, preparation and execution of this Agreement and the
transactions contemplated hereby ("Costs"). If this Agreement is terminated
pursuant to Section

<PAGE>

8.01(f) or (g), the Company will within five business days following any such
termination pay to Parent in cash by wire transfer in immediately available
funds to an account designated by Parent (i) in reimbursement for Parent's
expenses an amount equal to the aggregate amount of Parent's reasonable
documented Costs incurred in connection with pursuing the transactions
contemplated by this Agreement, including, without limitation, legal, accounting
and investment banking fees, up to but not in excess of $10,000,000 in the
aggregate and (ii) a payment in an amount equal to $18,000,000 (the "Termination
Fee"). Purchaser shall terminate the Offer as soon as practicable following
termination of this Agreement for any reason.

         (b) The prevailing party in any legal action undertaken to enforce this
Agreement or any provision hereof shall be entitled to recover from the other
party the costs and expenses (including attorneys' and expert witness fees)
incurred in connection with such action.

         SECTION 8.03 Amendment. Subject to Section 1.03(c), this Agreement and
the Offer may be amended by the Company, Parent and the Purchaser at any time
before or after any approval of this Agreement by the stockholders of the
Company but, after any the purchase of shares pursuant to the Offer, no
amendment shall be made which decreases the Merger Consideration or which
materially adversely affects the rights of the Company's stockholders hereunder
without the approval of such stockholders. This Agreement and the Offer may not
be amended except by an instrument in writing signed on behalf of all the
parties.

         SECTION 8.04 Extension; Waiver. Subject to Section 1.03(c), at any time
prior to the Effective Time, the parties hereto may (i) extend the time for the
performance of any of the obligations or other acts of any other party hereto,
(ii) waive any inaccuracies in the representations and warranties contained
herein by any other party or in any document, certificate or writing delivered
pursuant hereto by any other party or (iii) waive compliance with any of the
agreements of any other party or with any conditions to its own obligations. Any
agreement on the part of any party to any such extension or waiver shall be
valid only if set forth in an instrument in writing signed on behalf of such
party.

                                   ARTICLE IX

                                  MISCELLANEOUS

         SECTION 9.01 Non-Survival of Representations and Warranties. The
representations and warranties made in this Agreement shall not survive beyond
the Effective Time. Notwithstanding the foregoing, the agreements set forth in
Section 3.02, the last sentence of Section 6.02, Section 6.06 and Section 6.07
shall survive the Effective Time indefinitely (except to the extent a shorter
period of time is explicitly specified therein).

         SECTION 9.02 Entire Agreement; Assignment.

         (a) This Agreement (including the documents and the instruments
referred to 

<PAGE>

herein) and the letter agreement dated March 6, 1998 between Credit Suisse First
Boston Corporation and Addington Enterprises Inc. (the "Confidentiality
Agreement"), constitute the entire agreement and supersede all prior agreements
and understandings, both written and oral, among the parties with respect to the
subject matter hereof and thereof.

         (b) Neither this Agreement nor any of the rights, interests or
obligations hereunder will be assigned by any of the parties hereto (whether by
operation of law or otherwise) without the prior written consent of the other
party; provided however that after the Effective Time Parent and/or the

         jurisdiction or any statute, rule, regulation, legislation, or order
         shall be enacted, entered, enforced, promulgated, amended or issued by

         affiliate of Parent, or the consummation of the Offer or the Merger or

         prevent the taking of such 

<PAGE>

         action, or the enactment, enforcement, promulgation, amendment,
         issuance or application of any statute, rule, regulation, legislation,
         judgment, order or injunction, offer to accept an order to divest such
         of the Company's or Parent's assets and businesses as may be necessary
         to forestall such injunction or order and to hold separate such assets
         and business pending such divestiture; (ii) any proceeding brought by
         an administrative agency or commission or other domestic Governmental
         Entity seeking any of the foregoing shall be pending; or (iii) any
         action or proceeding shall be commenced following the date of the

         one or more of its representations and warranties set forth in the
         Merger Agreement or failed to perform any of its obligations, covenants

terms. Pursuant to the Merger Agreement, Parent and Purchaser have agreed to use
their respective reasonable best efforts to obtain financing for the Offer and
to cause all other conditions to be fulfilled.

The foregoing conditions are for the benefit of Parent and the Purchaser and may
be asserted by Parent or the Purchaser regardless of the circumstances giving
rise to any such conditions and may be waived by Parent or the Purchaser in
whole or in part at any time and from time to time in their reasonable
discretion, in each case, subject to the terms of the Merger Agreement. The
failure by Parent or the Purchaser at any time to exercise any of the foregoing
rights shall not be deemed a waiver of any such right and each such Right shall
be deemed an ongoing right which may be asserted at any time and from time to
time.

The capitalized terms used in this Annex I shall have the meanings set forth in
the Agreement to which it is annexed, except that the term "Merger Agreement"
shall be deemed to refer to the Agreement to which this Annex I is appended.

(1) Mr. Willson's employment commenced in March 1995.
 
EMPLOYMENT AGREEMENTS
 
    Mr. Vyas has an employment agreement with the Company, dated as of February
24, 1993, as amended, which provides for his employment by the Company as
President and, if so elected, Chief Executive Officer at an annual salary and
bonus to be determined by the Board of Directors. Mr. Vyas' employment may be
terminated by him or the Company on 30 days' notice. If he is terminated for
other than cause, or he terminates his employment as a result of an unacceptable
change in his duties, a change
 
                                       1



<PAGE>
of control of Zeigler or other "Good Reason" (as defined therein), Mr. Vyas
would be entitled to severance payments for three years following termination in
an amount equal to three times his Average Compensation as well as certain other
benefits related to his supplemental retirement payments and acceleration of
vesting of his stock options. In the event of Mr. Vyas' death, his estate is
entitled to receive two times his Average Compensation. The employment agreement
provides that upon retirement, Mr. Vyas would be entitled to supplemental
retirement payments equal to the excess, if any, of (i) the amount he would
receive under the Company's pension plan (described below) if effect were not
given to limitations imposed by the Internal Revenue Code and if his
compensation included his bonuses over (ii) the annual amount payable to Mr.
Vyas under such pension plan plus annual social security benefits payable to
him. The estimated annual supplemental retirement payment payable to Mr. Vyas
upon his normal retirement date was $315,000 as of December 31, 1997. Mr. Vyas'
employment agreement also provides that he will not compete with the Company
during the employment term and for a period of one year following termination.
 
CHANGE IN CONTROL ARRANGEMENTS
 
    SPECIAL BONUS AND SEVERANCE PAY PLAN. In December, 1997, Zeigler announced
that it was reviewing strategic alternatives to increase stockholder value,
including a possible sale of the Company. In connection therewith Zeigler
adopted a special bonus and severance pay plan which provides that certain of
Zeigler's executives and other non-union personnel would receive specified
retention payments if a sale of Zeigler or other change of control (as defined
in the plan) occurred prior to December 31, 1998 and severance payments if the
employment of such person were terminated in certain circumstances during the
twelve months following such sale or other change of control. The plan also
provides that any unvested stock options will vest upon a sale of the Company or
other change in control. Any severance payment otherwise due an executive under
this plan would be reduced by severance amounts payable under his or her
employment contract. The amounts of such payments vary based on the
classification of the covered employee and his or her compensation level and
tenure with the Company. The amounts payable to Messrs. Blackburn, Willson, Lane
and Young under the plan, as of the date of this Proxy Statement are:
$220,000.00, $164,983.50, $143,550.00 and $164,983.50 respectively, in the event
of change in control and $440,000.00, $330,016.50, $291,450.00 and $330,016.50,
in the event such individual becomes entitled to severance payments (after
reduction of the amount paid upon a change in control). In addition, if a sale
of the Company occurs during 1998 each of the named individuals would be
entitled to receive a special bonus of $150,000 and possibly other payments
determined in the discretion of Messrs. Manley and Reilly. Change in control
arrangements applicable to Mr. Vyas are discussed in "Employment Agreements"
above.
 
STOCK APPRECIATION AND STOCK OPTION PLANS
 
    STOCK APPRECIATION PLAN. Certain key employees of the Company and its
subsidiaries have been granted stock appreciation units ("SAUs") under the
Company's Stock Appreciation Plan (the "Stock Appreciation Plan"). Each
participant in the Stock Appreciation Plan is entitled to receive a cash payment
at "maturity" for each SAU which has become vested based upon the increase in
fair value (as defined) of a share of the Company's Common Stock from the
effective date of the award of the SAU. Vested SAUs mature on the earliest of
the termination of the participant's employment with the Company, the sixth
anniversary of the date of grant, the sale of the Company or the written
election of the participant. The Stock Appreciation Plan is administered by the
Compensation Committee of the Board of Directors. There were 73,600 SAUs
outstanding as of December 31, 1997, all of which are fully vested and mature in
1998. Under the Stock Appreciation Plan, "fair value" is based on the "market
price" of the Company's Common Stock.
 
    STOCK OPTION PLAN. In 1994 the Company's Board of Directors and stockholders
adopted its Stock Option Plan (the "Option Plan"). A total of 2,560,000 shares
of Common Stock were reserved for issuance upon exercise of options granted
under the Option Plan. The purpose of the Option Plan is to attract and
 
                                       2
<PAGE>
retrain qualified personnel and to provide additional incentive to executive and
other key employees of the Company and its subsidiaries. The Option Plan is
administered by the Compensation Committee (the "Committee") which determines
the terms of the options granted under the Option Plan, including the exercise
price, number of shares subject to the option and exercisability. Generally,
options may be transferred by the optionees by will or the laws of descent or
distribution or to such transferees and on such terms and conditions as the
Committee approves. Each option may be exercised, during the lifetime of the
optionee, only by the optionee. The exercise price of all options granted under
the Option Plan must equal at least the fair market value of the Common Stock of
the Company on the date of grant.
 
    Unless the Committee specifies otherwise in the option grant, options
granted will vest and become exercisable with respect to 20% of the Common Stock
issuable upon exercise thereof on each anniversary of the grant date, and the
reminder shall vest on the fifth anniversary of the grant date. At the
discretion of the Committee, options may be made exercisable in one or more
installments upon (i) occurrence of certain events, (ii) passage of time, (iii)
fulfillment of certain conditions, or (iv) achievement of corporate performance
goals. In the event of the Sale of the Company (as defined therein), the
Committee may provide, in its discretion, that (i) outstanding options shall
become immediately exercisable and shall terminate if not exercised as of the
date of the Sale of the Company or any other designated date, or (ii) that such
options shall only provide the right to receive the excess of the consideration
per share of Common Stock offered in such Sale of the Company over the exercise
price of such options.

Board of Directors
Zeigler Coal Holding Company
50 Jerome Lane
Fairview Heights, Illinois 62208

Members of the Board:

You have asked us to advise you with respect to the fairness to the holders 
of the common stock of Zeigler Coal Holding Company ("Zeigler") from a 
financial point of view of the consideration to be received by such holders 
pursuant to the terms and subject to the conditions set forth in the 
Agreement and Plan of Merger, dated as of August 3, 1998 (the "Merger 
Agreement"), by and among AEI Resources, Inc. ("AEI"), Zeigler Acquisition 
Corporation ("Sub"), a wholly owned subsidiary of AEI, and Zeigler. The 
Merger Agreement provides for, among other things, (i) a tender offer by Sub 
to acquire all of the outstanding shares of the common stock, par value $0.01
per share, of Zeigler (the "Zeigler Common Stock") at a purchase price of 
$21.25 per share, net to the seller in cash (the "Cash Consideration" and, 
such tender offer, the "Tender Offer") and (ii) subsequent to the Tender 
Offer, the merger of Sub with and into Zeigler (the "Merger" and, together 
with the Tender Offer, the "Transaction") pursuant to which each outstanding 
share of Zeigler Common Stock not acquired in the Tender Offer will be 
converted into the right to the Cash Consideration.

In arriving at our opinion, we have reviewed the Merger Agreement and certain 
publicly available business and financial information relating to Zeigler. 
We have also reviewed certain other information relating to Zeigler, 
including financial forecasts, provided to or discussed with us by Zeigler, 
and have met with the management of Zeigler to discuss the business and 
prospects of Zeigler. We have also considered certain financial and stock 
market data of Zeigler, and we have compared those data with similar data for 
other publicly held companies in businesses similar to Zeigler, and we have 
considered, to the extent publicly available, the financial terms of certain 
other business combinations and other transactions which have recently been 
effected. We also considered such other information, financial studies, 
analyses and investigations and financial, economic and market criteria which 
we deemed relevant.

In connection with our review, we have not assumed any responsibility for 
independent verification of any of the foregoing information and have relied 
on its being complete and accurate in all material respects. With respect to 
the financial forecasts, we have assumed that such forecasts have been 
reasonably prepared on bases reflecting the best currently available 
estimates and judgments of the management of Zeigler as to the future 
financial performance of Zeigler. In addition, we have not been requested to 
make, and have not made, an independent evaluation or appraisal of the assets 
or liabilities (contingent or otherwise) of Zeigler, nor have we been 
furnished with any such evaluations or appraisals. Our opinion is necessarily 
based upon information available to us, and financial, economic, market and 
other conditions as they exist and can be evaluated, on the date hereof.

Board of Directors
Zeigler Coal Holding Company

Page 2

We have acted as financial advisor to Zeigler in connection with the 
Transaction and will receive a fee for such services, a significant portion 
of which is contingent upon the consummation of the Transaction. In the past, 
we have provided financial services to Zeigler unrelated to the proposed 
Transaction, for which services we have received compensation. In the 
ordinary course of business, Credit Suisse First Boston and its affiliates 
may actively trade the debt and equity securities of Zeigler for their own 
accounts and for the accounts of customers and, accordingly, may at any time 
hold long or short positions in such securities.

It is understood that this letter is from the Board of Directors of Zeigler 
in connection with its evaluation of the Transaction, does not constitute a 
recommendation to any stockholder as to whether such stockholder should 
tender shares of Zeigler Common Stock pursuant to the Tender Offer or how 
such stockholder should vote with respect to any matters relating to the 
Merger, and is not to be quoted or referred to, in whole or in part, in any 
registration statement, prospectus or proxy statement, or in any other 
document used in connection with the offering or sale of securities, nor 
shall this letter be used for any other purposes, without our prior written 
consent.

Based upon and subject to the foregoing, it is our opinion that, as of the 
date hereof, the Cash Consideration to be received in the Transaction by the 
holders of Zeigler Common Stock (other than AEI and its affiliates) is fair 
to such holders from a financial point of view.

Very truly yours,

CREDIT SUISSE FIRST BOSTON CORPORATION

Dear Stockholders:
 
    We are pleased to inform you that our Company has entered into an Agreement
and Plan of Merger, dated as of August 3, 1998 (the "Merger Agreement"), with
AEI Resources, Inc. ("Parent") and Zeigler Acquisition Corporation, a
wholly-owned subsidiary of Parent ("Purchaser"). Pursuant to the Merger
Agreement, Purchaser has today commenced a cash tender offer (the "Offer") to
purchase all of the outstanding common stock, $.01 par value (the "Shares"), of
the Company at a purchase price of $21.25 per Share, net to the stockholder in
cash. Following the successful consummation of the Offer, Purchaser will be
merged with and into the Company (the "Merger") and the Company will become a
wholly-owned subsidiary of Parent.
 
    YOUR BOARD OF DIRECTORS HAS UNANIMOUSLY DETERMINED THAT THE OFFER AND THE
MERGER ARE FAIR TO AND IN THE BEST INTERESTS OF THE COMPANY AND ITS
STOCKHOLDERS, HAS APPROVED THE MERGER AGREEMENT AND THE TRANSACTIONS
CONTEMPLATED THEREBY, INCLUDING THE OFFER AND THE MERGER, AND RECOMMENDS THAT
ALL HOLDERS OF SHARES ACCEPT THE OFFER.
 
    In arriving at its recommendation, the Board of Directors gave careful
consideration to the factors described in the attached Schedule 14D-9 that is
being filed today with the Securities and Exchange Commission, including, among
other things, the opinion dated August 3, 1998 of Credit Suisse First Boston
Corporation, the Company's financial advisor, to the effect that, as of such
date and based upon and subject to certain matters stated in such opinion, the
$21.25 per Share cash consideration to be received by holders of Shares (other
than Parent and its affiliates) in the Offer and the Merger was fair, from a
financial point of view, to such holders.
 
    Certain stockholders and directors of the Company owning approximately 33%
of the Shares on a fully diluted basis have agreed to tender their Shares.
 
    In addition to the attached Schedule 14D-9, enclosed is the Offer to
Purchase dated August 5, 1998 together with related materials, including a
Letter of Transmittal, to be used for tendering your Shares pursuant to the
Offer. These documents state the terms and conditions of the Offer and the
subsequent Merger, provide detailed information about the transactions and
include instructions as to how to tender your Shares. We urge you to read these
documents carefully in making your decision with respect to tendering your
Shares pursuant to the Offer.
 
Very truly yours,
