Convertible Note in the original principal amount of $398,000 pursuant to the
terms of and in connection with the

<Page>

transactions contemplated by the Purchase Agreement. Executive represents and
warrants to the Company, and agrees and acknowledges that:

                  (i)     The Executive Securities acquired by Executive
     pursuant to the Purchase Agreement are and shall be acquired for
     Executive's own account, for investment purposes only and not with a
     present view to, or intention of, distribution or resale thereof in
     violation of the 1933 Act or any state securities laws and that,
     irrespective of any other provisions of this Agreement, the Executive
     Securities shall be Transferred only in compliance with all applicable
     federal and state securities laws, including, without limitation, the 1933
     Act.

                  (ii)    The Executive Securities are not registered under the
     1933 Act and must be held by Executive until such Executive Securities are
     registered under the 1933 Act or an exemption from such registration is
     available; the Company shall have no obligation to take any actions that
     may be necessary to make available any exemption from registration under
     the 1933 Act; and the Company shall place "stop transfer" restrictions on
     the party responsible for recording Transfers of Executive Securities in
     violation of the foregoing provisions of this clause (ii).

                  (iii)   Executive is familiar with Rule 144 ("RULE 144")
     adopted by the Securities and Exchange Commission ("SEC") which establishes
     guidelines governing, among other things, the resale of "restricted
     securities" (securities, such as Executive Securities, which are acquired
     from the issuer of such securities in a transaction not involving any
     Public Offering).

                  (iv)    Rule 144 is not presently available for Transfers of
     the Executive Securities because, among other things, the Company is not
     presently required to file the reports required to be filed by Section
     15(d) of the 1934 Act, and does not have a class of securities registered
     pursuant to Section 12 of that statute; and, even if the Company were
     required to file reports under the 1934 Act, and had filed all reports
     required to be filed, reliance on Rule 144 to Transfer securities is
     subject to other restrictions and limitations, as set forth in Rule 144.

                  (v)     In connection with any Transfer of Executive
     Securities under Rule 144 or pursuant to any other exemption, Executive
     may, at the option of the Company, be required to deliver to the Company an
     opinion from counsel for Executive (reasonably acceptable to the Company)
     and/or receive an opinion from counsel for the Company, to the effect that
     all applicable federal and state securities law requirements have been met.

                  (vi)    Executive has been an executive employee of the Seller
     and is an executive employee of Beacon Operating.

                  (vii)   Executive is able to evaluate the risks and merits of
     the investment in the Executive Securities and of making an informed
     investment decision with respect thereto.

<Page>

                  (viii)  Executive is able to bear the economic risk of
     Executive's investment in the Executive Securities for an indefinite period
     of time because the Executive Securities have not been registered under the
     193 3 Act and, therefore, cannot be sold unless subsequently registered
     under the 1933 Act or unless an exemption from such registration is
     available.

                  (ix)    Executive has reviewed the financial and other
     information with respect to the Company, Beacon Operating and the
     Subsidiaries previously provided to Executive, and all such other documents
     and information made available to, or requested by, Executive, and
     Executive has had the opportunity to ask questions and receive answers
     concerning all such materials and the terms and conditions of the offering
     of the Executive Securities. Executive has had full access to such other
     information and materials concerning the Company as Executive has
     requested. The Company has answered all inquiries that Executive has made
     to the Company relating to the Company and the sale of the Executive
     Securities hereunder.

                  (x)     The execution, delivery and performance of this
     Agreement by Executive does not and shall not conflict with, violate or
     cause a breach of any agreement, contract or instrument to which Executive
     is a party or any judgment, order or decree to which Executive is subject.

                  (xi)    The Executive has not granted any proxy or become
     party to any voting trust or other agreement which is inconsistent with,
     conflicts with or violates any provision of this Agreement.

                  (xii)   Executive has the legal capacity to execute and
     perform this Agreement. This Agreement has been duly executed and delivered
     by Executive, and constitutes a valid and legally binding obligation of
     Executive, enforceable against him in accordance with its terms (except to
     the extent that enforcement may be affected by laws relating to bankruptcy,
     reorganization, insolvency and creditors' rights and by the availability of
     injunctive relief, specific performance and other equitable remedies).
     Executive's spouse has the legal capacity to execute and deliver the
     Spousal Consent attached to this Agreement (the "SPOUSAL CONSENT") and to
     deliver the Spousal Consent and such consent has been validly executed and
     delivered.

            (b)   COMPANY REPRESENTATIONS AND WARRANTIES. The Company represents
and warrants to Executive that:

                  (i)     The Company is duly organized, validly existing and in

<Page>

                  (ii)    The execution, delivery and performance of his
     Agreement by the Company does not and shall not conflict with, violate or
     cause a breach of any of the terms or provisions of the Certificate of
     Incorporation of the Company or its by-laws, or of any agreement, contract
     or instrument to which the Company is a party, or any judgment, order or
     decree to which the Company is subject.

                  (iii)   On the date of this Agreement and after giving effect
     to the transactions contemplated by (1) this Agreement, (2) other Executive
     Securities Agreements of even date herewith between the Company and other
     officers and employees of the Company, (3) the Investor Securities
     Agreement dated of even date herewith among the Company, CHS, and certain
     investors, and (4) certain agreements and instruments entered into with and

     anti-dilution provisions). All Shares heretofore issued and delivered by
     the Company to any Holder have been, and all Shares to be issued by the
     Company to any Holder pursuant to this Agreement, when issued and
     delivered, shall be, duly authorized, validly issued, fully paid and
     nonassessable. The Executive Securities are subject to dilution by future
     issuances of securities of the Company including by issuance of common
     stock to lenders pursuant to warrants.

            (c)   ADDITIONAL AGREEMENTS AND UNDERSTANDINGS. As an additional
inducement to the Company to issue Executive Shares to Executive, Executive
acknowledges and agrees that:

                  (i)     Neither the ownership of Executive Shares by the
     Executive nor any provision contained herein shall entitle Executive to
     remain in the employment of the Company or any of its Subsidiaries or
     affect the right of the Company to terminate Executive's employment at
     anytime for any reason.

                  (ii)    Shares issued by the Company pursuant to a stock
     dividend, stock split, reclassification or like action, or pursuant to the

     same options with respect to, the Shares which were split or reclassified
     or with respect to which a stock dividend was paid or rights to purchase
     Shares on a proportionate basis were granted. In the event of a merger of
     the Company where this Agreement does not terminate, partnership units,
     membership units or shares of common stock (and/or securities convertible
     into such units or shares) which are issued in exchange for Shares shall
     thereafter be deemed to be Shares subject to the terms of this Agreement.

                  (iii)   Any person to whom Executive Securities are to be
     Transferred (except pursuant to a Public Offering) shall execute and
     deliver, as a condition to such Transfer, whatever documents are deemed
     reasonably necessary by the Company, in consultation with its counsel, to
     evidence such party's joinder in, acceptance of, and agreement with, the
     obligations with respect to the Executive Securities contained in this
     Agreement.

                  (iv)    Within thirty (30) days from the date hereof,
     Executive shall make an election with the Internal Revenue Service under
     Section 83(b) of the Internal Revenue Code and the regulations promulgated
     thereunder in form and substance reasonably satisfactory to the Company.

                  (v)     Except with the prior written consent of CHS, (A)
     Executive shall not grant any proxy or become party to any voting trust or
     other agreement with respect to the Executive Securities or any interest
     therein (provided, however, that Executive may enter into that certain
     Stock Appreciation Rights Agreement dated as of even date herewith, with
     John Swansburg, in the form provided to the Company on the date hereof,
     which shall not be amended after the date hereof) and (B) Executive shall
     not pledge any securities to secure indebtedness.

                  (vi)    Pursuant to a management agreement of even date
     herewith, the Company and Beacon Operating will pay to CHS (or one of its
     Affiliates) management fees in the amount of $300,000 per year (payable
     monthly) plus reasonable out of pocket expenses.

     3.     REPURCHASE OPTION.

            (a)   GENERAL. Upon the termination of Executive's employment with
Beacon Operating or any of its Subsidiaries for any reason ("TERMINATION"), all
Executive Securities, whether held by Executive or one or more of Executive's
transferees (collectively, the "AVAILABLE SECURITIES"), shall be subject to
repurchase by CHS and the Company pursuant to the terms and conditions set forth
in this Section 3 (the "REPURCHASE OPTION").

            (b)   COMPANY OPTION. The Board, acting in good faith, may elect (in
its sole discretion) to cause the Company to purchase all or any portion of the
Available Securities pursuant to the Repurchase Option by delivering written
notice (the "REPURCHASE NOTICE") to CHS and Executive within thirty (30) days
following Termination. The Repurchase Notice shall set forth the number and
amount of Available Securities to be acquired from each Holder, the aggregate
consideration to be paid for such securities and the time and place for the
closing of such purchase.

            (c)   CHS OPTION. If for any reason the Company does not elect to
purchase all of the Available Securities pursuant to the Repurchase Option, CHS
may elect (in its sole discretion) to exercise the Repurchase Option for all
(but not less than all) of the Available Securities which the Company has not
elected to purchase (the "SECURITIES AVAILABLE FOR CHS"). Within sixty (60) days
following Termination, CHS may elect to purchase all (but not less than all) of
the Securities Available for CHS by giving written notice to Executive as to the
number

                                       10
<Page>

and amount of securities being purchased by CHS from each Holder (the
"SUPPLEMENTAL REPURCHASE NOTICE").

            (d)   REPURCHASE PRICE. Upon exercise of the Repurchase Option, the
purchase price for the Available Securities (the "REPURCHASE PRICE") shall be as
follows:

                  (i)     if the Repurchase Option is triggered by termination
     of Executive's employment by reason of Executive's death, Executive's
     Disability, Vested Resignation of Executive, termination of Executive's
     employment by Beacon Operating without Just Cause, or termination for any
     other reason (other than those described in subsection 3(d)(ii) below), the
     Repurchase Price shall be Fair Market Value of the Available Securities as
     of the date of Termination; and

                  (ii)    if the Repurchase Option is triggered by termination
     of Executive's employment by the Company or any Subsidiary for Just Cause
     or Resignation of the Executive (other than a Vested Resignation), the
     purchase price of the Available Securities shall be the lesser of: (A) the
     Founder's Cost (in the case of Executive Shares and Options) and the
     Outstanding Indebtedness (in the case of Subordinated Notes and other notes
     constituting Available Securities); and (B) the Fair Market Value of the
     Available Securities.

The Repurchase Price for the Available Securities under this Section 3(d) shall
be computed as of the date of Termination. The Repurchase Price shall be
calculated by the Board within thirty (30) days following Termination (provided,
however, that Fair Market Value shall be determined in accordance with the
definition thereof in Section 1). Notwithstanding anything to the contrary
herein contained, if the Company and CHS collectively have elected to purchase
less than all of the Available Securities, then the Company and CHS shall be
deemed to have elected not to purchase any of the Available Securities pursuant
to the Repurchase Option.

            (e)   CLOSING. If and only if the Company and CHS collectively have
elected to purchase all (but not less than all) of the Available Securities, the
purchase of Available Securities pursuant to this Section 3 shall be consummated
at the Company's principal office at 10:00 a.m., on the thirtieth (30th) day
next following the final determination of the Repurchase Price as provided in
Section 3(d), or on such earlier day as designated by CHS or the Company, as the
case may be, in its sole discretion, upon not less than ten (10) days prior
notice to Executive. If such date is a Saturday, Sunday or legal holiday, the
closing shall occur at the same time and place on the next succeeding business
day. Subject to Section 5 hereof, at the option of the Company and/or CHS, the
Person exercising the Repurchase Option shall pay for the Available Securities
to be purchased pursuant to the Repurchase Option by (i) delivery of a cashier's
check or wire transfer of immediately available funds or (ii) delivery of a
negotiable secured junior subordinated promissory note (the "Repurchase Note")
in the form of EXHIBIT A hereto, the principal amount of which shall bear
interest at the rate of eight percent (8%) per annum, with interest and a pro
rata portion of principal payable quarterly over a three-year period following
delivery of the Repurchase Note, and with such additional terms (including
subordination provisions) as shall be required by the senior lenders to the
Company and its Subsidiaries. Whenever a Repurchase Note is used pursuant to any
provision of this Agreement, the obligations of the Company or CHS (as the case
may be) under the Repurchase Note shall be

                                       11
<Page>

secured by a pledge of all Executive Shares purchased pursuant to delivery of
such Repurchase Note. The pledge of the Executive Shares shall be made pursuant
to a pledge agreement in the form of EXHIBIT B hereto. The purchasers of
Executive Securities to be purchased pursuant to the Repurchase Option hereunder
shall be entitled to receive customary representations and warranties as to
ownership, title, authority to sell and the like from the Holders regarding such
sale and to receive such other evidence, including applicable inheritance and
estate tax waivers, as may reasonably be necessary to effect the purchase of the
Executive Securities to be purchased pursuant to the Repurchase Option.

            (f)   FAILURE TO DELIVER SHARES. If Executive or any other Holder of
Executive Securities whose Executive Securities are to be purchased pursuant to
Section 3, 4 or 6 fails to deliver them on the scheduled closing date of such
purchase, the Company or CHS (as the case may be) may elect to deposit the
consideration representing the purchase price of the Executive Securities with
the Company's attorney (or any other third party, including a bank or a
financial institution), as escrowee. In the event of the foregoing election, the
Executive Securities shall be deemed for all purposes (including the right to
vote and receive payment for dividends) to have been Transferred to the
purchasers thereof and the Company shall issue new certificates representing the
Executive Securities to the Company, CHS or their respective designees, as the
case may be, and the certificates or instruments registered in the name of the
Person obligated to sell such Executive Securities shall be deemed to have been
canceled and to represent solely a right to receive payment of the purchase
price, without interest, from the escrow funds. If, prior to the third (3rd)
anniversary of the scheduled closing date for the purchase pursuant to Sections
3, 4 or 6, the proceeds of sale have not been claimed by the Executive or other
seller of the Executive Securities, the escrow deposit (and any interest earned
thereon) shall be returned to the Person originally depositing the same, and the
transferors whose Executive Securities were so purchased shall look solely to
the purchasers thereof for payment of the purchase price. The escrowee shall not
be liable for any action or inaction taken by it in good faith.

            (g)   TERMINATION OF REPURCHASE OPTION. The rights of the Company
and/or CHS to purchase Executive Securities pursuant to this Section 3 shall
terminate upon the consummation of a Sale of the Company or a Public Offering.

            (h)   PRICE PROTECTION. In the event that the Company or CHS
exercises a Repurchase Option following termination of Executive's employment
with Beacon Operating by Beacon Operating without Just Cause, and a Sale of the
Company or Beacon Operating is consummated during the twelve (12) month period
following the date of the Closing pursuant to exercise of such Repurchase
Option, the Company shall pay to each Holder of Available Securities which sold
such securities pursuant to the exercise of such Repurchase Option, as
additional purchase price for the Executive Securities purchased pursuant to
such Repurchase Option, an amount (the "Additional Amount") equal to the
aggregate amount, if any, by which such Holder's Sale Price (as defined herein)
would exceed the Repurchase Price paid to such Holder with respect to the
Available Securities sold by such Holder pursuant to the Repurchase Option.
"Sale Price" shall mean the amount which would have been realized by a Holder of
Available Securities as a result of a Sale of the Company had the purchase of
such Holder's Available Securities pursuant to the exercise of the Repurchase
Option not occurred and such Holder had participated in, or received proceeds as
a result of, such Sale of the Company (assuming exercise of all outstanding
options, warrants and other convertible securities). For

                                       12
<Page>

purposes of computing the Sale Price, (i) the computation shall take into
account the portion of all transaction and other costs which such Holder would
have had to bear as a result of participation in the Sale of the Company; (ii)
if any part of the consideration in connection with a Sale of the Company is
paid in property or securities, the value of said consideration shall be
computed by determining the fair market value of such property or securities at
the time of closing of the Sale of the Company (which, in the case of securities
shall, if applicable, take into account reductions or discounts in the fair
market value resulting from such securities being "restricted securities" within
the meaning of Rule 144); (iii) if the consideration in connection with a Sale
of the Company is payable in installments or otherwise on a deferred basis, the
value of said consideration shall be computed at the present value thereof as of
the date of consummation of the Sale of the Company, taking into account
interest payable on said installments according to the terms thereof and using
as a discount rate the "prime rate" then in effect at the First National Bank of
Chicago; and (iv) an equitable adjustment shall be made to take into account all
Common Stock splits, Common Stock dividends and other changes to the Company's
capital structure occurring between the date the Repurchase Option is exercised
and the date on which the Sale of the Company takes place; provided, however,
that all subsequent issuances of securities or other interests by the Company
following exercise of the Repurchase Option which would have the effect of
diluting the seller's ownership interest in the Company shall so dilute such
ownership interest for purposes of this paragraph. The Additional Amount shall
be payable by the Company in cash (or, if not cash, the same property received
in the Sale of the Company, in which case subsection (ii) above shall not apply)
not later than thirty (30) days after the date on which the Sale of the Company
is consummated, unless the following sentence is applicable. In the case of a
Sale of the Company where deferred payments (including, without limitation,
pursuant to a promissory note or an escrow arrangement) are to be made by the
purchaser, the Additional Amount shall be paid at such time(s) as the purchaser
makes payments to the Company or all other holders of Common Stock, as the case
may be (in which case subsection (iii) shall not apply). The Additional Amount
shall be determined by the independent certified public accountants regularly
engaged by the Company, whose determination shall be final and binding on the
parties hereto.

     4.     PUT.

            (a)   GENERALLY. Upon the occurrence of a termination of Executive's
employment with Beacon Operating and its Subsidiaries as a result of Executive's
death or Disability or as a result of termination by Beacon Operating of
Executive's employment with Beacon Operating without Just Cause (other than a
termination which results from expiration of his employment agreement at the end
of its term or thereafter) (a "PUT EVENT"), Executive may require the Company to
repurchase all (but not less than all) of the Executive Securities owned by the
Executive as of the date of such termination, pursuant to the terms and
conditions in this Section 4 (the "Put").

            (b)   PUT NOTICE. Upon the occurrence of a Put Event, Executive (or
his personal representative, if Executive is deceased or incompetent) may
exercise the Put by delivering written notice (the "PUT NOTICE") to the Company
within thirty (30) days following the occurrence of the Put Event.

                                       13
<Page>

            (c)   PUT PRICE. Upon the exercise of the Put, the purchase price
for the Executive Securities (the "PUT PRICE") shall be the Fair Market Value of
such securities computed as of the date of the Put Event. The Board shall
calculate the Put Price within thirty (30) days following delivery of a Put
Notice (provided, however, that Fair Market Value shall be determined in
accordance with the definition thereof in Section 1).

            (d)   MANNER OF PAYMENT. Subject to Section 5, the Put Price payable
in connection with the exercise of a Put Option shall, at the option of the
Company, be paid either (i) in full in cash on the Put Closing Date (as defined
herein) or (ii) by delivery of a Repurchase Note.

            (e)   CLOSING. The closing of the purchase of Executive Securities
pursuant to the Put (the "PUT CLOSING") shall take place on the date (the "PUT
CLOSING DATE") designated by the Company in a written notice to Executive, which
date shall be not more than thirty (30) days after final determination of the
Put Price as provided in Section 4(e).

            (f)   TERMINATION OF RIGHT. The right of Executive to require the
Company to repurchase Executive Securities pursuant to this paragraph 4 will
terminate immediately after consummation of a Sale of the Company or a Public
Offering.

     5.     MANNER OF PAYMENT AND RESTRICTIONS ON THE COMPANY'S OBLIGATION TO
PURCHASE.

            (a)   GENERAL RESTRICTION. Notwithstanding anything to the contrary
contained in this Agreement (other than the provisions of this paragraph
commencing after the third sentence hereof), the Company shall not be obligated
to purchase, pursuant to Section 4 or otherwise, such Executive Securities as
the Company may then be prohibited by law or bona fide contract from purchasing,
including, without limitation, the Delaware General Corporation Law (the
"DELAWARE ACT") and covenants contained in any loan agreements or other bona
fide agreements to which the Company or any Subsidiary is then a party. To the
extent such Executive Securities cannot be repurchased pursuant to applicable
contracts or law, the option contained in Section 4 shall be of no force and
effect and shall be null and void. For purposes of this Agreement, the Company
shall not be obligated to purchase Executive Securities if any loan or other
bona fide agreement to which any Subsidiary is a party or is bound would
prohibit the Subsidiaries from paying to the Company dividends or distributions
sufficient to permit the Company to pay the entire purchase price for such
Executive Securities. Notwithstanding the foregoing restriction set forth in
this subsection 5(a), Executive may exercise the Put in the event of Termination
by Beacon Operating of Executive's employment with Beacon Operating without Just
Cause, and upon exercise of the Put in such circumstances, the Company shall pay
to the Executive (as full or partial payment of the Put Price, as the case may
be) an amount ("Put Cost") equal to the lesser of (a) the Founder's Cost (in the
case of the Executive Shares then held by Executive and originally issued upon
conversion of the Convertible Note), or the then outstanding principal balance
of the Convertible Note held by Executive if not converted into common stock,
plus the outstanding principal balance of the $1,194,000 Subordinated Note
included in the Executive Securities held by Executive; and (b) the Fair Market
Value of such Executive Securities. The Put Cost shall be paid by delivery of a
note of the Company (the "PUT NOTE") in the form of the Repurchase Note,
provided, however, that, notwithstanding the terms for principal amortization
described in Section 3(e) hereof, the principal balance thereof will be

                                       14
<Page>

paid as follows: (1) $1,200,000 of the principal balance of the Put Note (or, if
less, the outstanding balance) would be paid on the first anniversary of the
date of issuance of the Put Note on the Put Closing Date and the remaining
balance, if any, would be paid on the second anniversary of the date of issuance
of the Put Note; PROVIDED, HOWEVER, that no payments of principal or interest
shall be due or made under or pursuant to the Put Note if, before or after such
payment, (i) there exists (or would exist as a result of such payment or
otherwise) a Default (as defined in the Credit Agreement) under, or a breach of
subsection 8.04(a) of, the Credit Agreement (or any similar provisions of a
replacement credit agreement which are not more restrictive than such section
8.04(a)), or (ii) the Company and Beacon Operating would have less than
$2,000,000 of availability under its revolving loan facility under the Credit
Agreement. Payments would not be due or made under the Put Note until permitted
pursuant to the preceding sentence. The remaining amount of the Put Price in the
event of exercise of the Put in the event of Termination without Just Cause
(i.e. the Put Price minus the Put Cost) would be paid in a form of a Repurchase
Note ("Profit Note"), provided that, notwithstanding anything to the contrary
contained in this Agreement, the outstanding principal balance of and accrued
interest under such Profit Note would be payable in full in a lump sum on the
third anniversary of the Put Closing Date, and provided further, however, that
no such payments would be due or made under the Profit Note unless and until the
Company is permitted to make such payments under the terms of its Credit
Agreement. The Put Note and Profit Note would each contain provisions reflecting
the foregoing agreements and such other terms as are reasonably satisfactory to
the Company's senior lender. If note(s) are delivered in satisfaction of the
purchase price of Executive Securities upon the exercise of a Put, the Executive
Securities purchased by the Company would be pledged to the seller of such
securities pursuant to a pledge agreement in the form of Exhibit B hereto.

            (b)   PAYMENT LIMITATION. Notwithstanding anything to the contrary
contained in this Agreement or in any Repurchase Note delivered pursuant to the
terms hereof, the Company's obligation to make a payment pursuant to a
Repurchase Note or other note delivered pursuant to Sections 3, 5 or 6 of this
Agreement shall be suspended to the extent and for so long as (x) the making of
such payment, together with the making of all other payments to be made during
such fiscal year on account of the Company's purchases of Executive Securities
pursuant to this Agreement and securities purchased pursuant to any other
agreements with shareholders of the Company, would result in a violation of the
Delaware Act or a breach of any covenant contained in any loan or other bona
fide agreement to which the Company or any of its Subsidiaries is a party, or
(y) the Company's Subsidiaries are unable to pay to the Company dividends or
other distributions sufficient to permit the Company to pay the entire purchase
price for such Executive Securities in cash as a result of applicable law or any
covenant contained in any bona fide agreement to which any of such Subsidiaries
are a party. If any portion of the Company's obligation to Executive or any of
Executive's transferees has been suspended for a period in excess of one hundred
eighty (180) days from the original due date of such obligation, Executive (or
such transferee), by written notice delivered to the Company, may elect to
rescind (on a pro rata basis between debt and equity) the sale of that portion
of the Executive Securities the proceeds of sale of which are represented by
unpaid notes made by the Company which are owed to Executive or such transferee.
If payments are suspended pursuant to this Section 5(b), and the Executive has
not elected to rescind the sale, at such time as the Company is able to resume
making payments without violation of the Delaware Act, applicable law or a
covenant in any bona fide agreement to which the Company or any of its
Subsidiaries is a party, the

                                       15
<Page>

Company shall first make payments of arrearage owed to the former shareholders
on a proportional (to the amount of arrearage) basis, and shall then make
regularly scheduled payments.

            (c)   If the Executive Securities are purchased by the Company
and/or CHS pursuant to the Repurchase Option exercised by the Company upon
termination of Executive's employment without Just Cause, then, concurrent with
such purchase, the Company shall purchase from Executive the outstanding loans
made on the date hereof by Executive to employees of Beacon Operating to
purchase Shares or other securities from the Company, which loans shall be in a
maximum amount of up to $480,000. The Company shall be entitled to receive
customary representations and warranties regarding such loans and to receive
such other evidence as may be reasonably necessary to effect such assignment.
The loan documents between Executive and such other management employees
(including a pledge agreement whereby such management employees pledge their
securities of the Company to the lender to secure such loans) shall be
assignable to the Company and shall not be amended or sold by the Executive
following the date hereof without the prior written consent of the Company (and
Executive shall not waive any of his rights thereunder).

     6.     RESTRICTIONS ON TRANSFER OF EXECUTIVE SECURITIES. This Section 6
shall apply to any proposed Transfer of Executive Securities. Notwithstanding
anything to the contrary contained herein, a Transfer of Executive Securities
shall not be valid or have any force or effect unless (i) such Transfer is made
in accordance with the provisions of this Agreement, (ii) such Transfer would
not result in a violation of any applicable federal or state securities law, and
(iii) the intended transferee of such Transfer is not engaged in a Competitive
Business, has not been engaged in a Competitive Business in the immediately
preceding two years, and is not developing a Competitive Business.

            (a)   TRANSFER OF EXECUTIVE SECURITIES. No Holder shall Transfer any
interest in any Executive Securities except pursuant to an Exempt Transaction or
pursuant to this Section 6. No Holder shall consummate any such Transfer (except
pursuant to an Exempt Transaction or pursuant to Section 6(c)) until sixty-one
(61) days following the latest of the delivery to the Company and CHS of the
Offer Notice (as defined below), unless all rights provided in Section 6(b) have
been exercised or waived, and the parties to the Transfer have been finally
determined pursuant to such exercises or waivers prior to the expiration of such
sixty-one (61) day period (the "ELECTION PERIOD"). Notwithstanding anything to
the contrary herein contained, except pursuant to an Exempt Transaction, neither
Executive nor any of his Permitted Transferees shall Transfer any interest in
Executive Securities (i) unless Executive or such Permitted Transferee(s) has
received a bona fide written offer to purchase such Executive Securities, (ii)
until the expiration of the Repurchase Options following Executive's Termination
and (iii) in any event without the prior written consent of a majority of the
members of the Board (which approval may be withheld for any reason or no
reason).

            (b)   FIRST REFUSAL RIGHT. If any Holder desires to Transfer any
Executive Securities other than in an Exempt Transaction or a transaction
pursuant to Section 6(c), such Holder (the "TRANSFERRING HOLDER") shall deliver
a written notice (the "OFFER NOTICE") to the Company and CHS. The Offer Notice
shall disclose in reasonable detail the identity of the proposed transferee(s)
including, without limitation, all parties holding controlling interests in

                                       16
<Page>

such proposed transferee), the proposed number, amount and type of Executive
Securities to be transferred and the proposed terms and conditions of the
Transfer and any other material information reasonably requested by the Board or
CHS and shall include a true and correct copy of the written offer to purchase
Executive Securities received by him. The delivery by the Transferring Holder of
the Offer Notice shall create the following two (2) options:

                  (i)     First, the Board, acting in good faith, may elect (in
     its sole discretion) to cause the Company to purchase all or any portion of
     the Executive Securities specified in the Offer Notice at the price and on
     the terms specified therein (provided, however, that any promissory note
     given by the Company pursuant to the terms of this Section 6 shall be
     subordinated to indebtedness owed to financial institutions on terms
     reasonably acceptable to such financial institutions) by delivering written
     notice of such election to the Transferring Holder as soon as practical,
     but in any event within thirty (30) days following the delivery of the
     Offer Notice (the "COMPANY OFFER PERIOD").

                  (ii)    If the Company has not elected to purchase all of the
     Executive Securities within the Company Offer Period, then CHS may elect
     (in its sole discretion) to purchase all (but not less than all) of the
     Executive Securities not elected to be purchased by the Company at the
     price and on the terms specified in the Offer Notice by delivering written
     notice of such election to the Transferring Holder as soon as practical,
     but in any event within sixty (60) days following the delivery of the Offer
     Notice.

If the Company and/or CHS have elected to purchase all (but not less than all)
of the Executive Securities offered by the Transferring Holder, the Transfer of
such Executive Securities to the Company and/or CHS, as the case may be, shall
be consummated as soon as practical after the delivery of the election notices,
but in any event within thirty (30) days following the expiration of the
Election Period. The purchasers of Executive Securities offered in the Offer
Notice hereunder shall be entitled to receive customary representations and
warranties as to ownership, title, authority to sell and the like from the
Holder regarding such sale and to receive such other evidence, including
applicable inheritance and estate tax waivers, as may reasonably be necessary to
effect the purchase of the Executive Securities offered in the Offer Notice.
Notwithstanding anything to the contrary herein contained, if the Company and
CHS collectively have elected to purchase less than all of the Executive
Securities offered by the Transferring Holder, then the Company and CHS shall be
deemed to have elected not to purchase any of the Executive Securities offered
by the Transferring Holder pursuant to this Section 6.

            (c)   TRANSFER SUBSEQUENT TO EXPIRATION OF ELECTION PERIOD. If the
Company and CHS have not collectively elected to purchase all Executive
Securities being offered, such Transferring Holder may, within sixty (60) days
following the expiration of the Election Period and subject to the provisions of
this Section 6 other than Section 6(b), Transfer such Executive Securities
referred to in the Offer Notice to the party or parties named therein at a price
no less than the price specified in the Offer Notice and on other terms and
conditions offered in the Offer Notice. Executive Securities Transferred
pursuant to the previous sentence shall thereafter continue to be subject to all
restrictions on Transfer and other provisions of this Agreement, including,
without limitation, the provisions of this Section 6 with respect to further
Transfers of the Executive Securities and a transferee, as a condition of any
such Transfer, shall agree in

                                       17
<Page>

writing to be bound by the provisions of this Agreement. Any Executive
Securities not transferred within such sixty (60) day period shall be subject to
the provisions of this Section 6 with respect to any subsequent Transfer.

            (d)   PERMITTED TRANSFERS. Anything contained in this Agreement to
the contrary notwithstanding, Executive Securities may be Transferred without
first complying with the provisions of Section 6 other than as provided in this
paragraph (d): (i) by Executive or a Permitted Transferee to CHS (it being
agreed and understood that CHS shall not be a Holder as a result of such
Transfer of Securities), (ii) by Executive to any member of such Executive's
Family Group, (iii) by a Permitted Transferee to Executive, (iv) to the personal
representative of Executive or a Permitted Transferee who is deceased or
adjudicated incompetent, (v) by the personal representative of Executive or a
Permitted Transferee who is deceased or adjudicated incompetent to any member of
such Executive's or Permitted Transferee's Family Group, or (vi) upon
termination of a trust or custodianship which is a Permitted Transferee of a
Holder, by the trustee of such trust or custodian of such custodianship to the
person or persons who, in accordance with the provisions of such trust or
custodianship, are entitled to receive the Executive Securities held in trust or
custody (collectively, the "PERMITTED TRANSFEREES"); provided that (A) the
restrictions contained in this Section 6 shall continue to be applicable to the
Executive Securities after any such Transfer, and (B) the Permitted Transferees
of such Executive Securities shall have agreed in writing to be bound by all of
the provisions of this Agreement affecting the Executive Securities so
transferred.

            (e)   CONSIDERATION FOR TRANSFER. Notwithstanding anything to the
contrary herein contained, except as may be required by Section 5 hereof, where
a Transfer is made for consideration, in no event shall any such Transfer by
Executive of Executive Securities be made for any consideration other than (i)
United States dollars payable in full upon consummation of such Transfer and/or
(ii) a promissory note with all amounts owed thereunder payable in United States
dollars.

     7.     PIGGYBACK REGISTRATION.

            (a)   For purposes of this Section 7, and without implication that
the contrary would otherwise be true, the term "COMPANY" shall include any
successor to the Company, the term "SHARES" shall include any securities of any
such successor and the term "EXECUTIVE SHARES" shall include securities of any
such successor issued in respect of Executive Shares. If, at any time or times,
the Company determines to file with the SEC a registration statement covering
any Shares to be issued or sold by the Company or CHS (or Affiliates of CHS),
other than Shares or other securities of the Company which are issuable in an
offering (i) to directors and employees of the Company or its Subsidiaries
pursuant to an employee stock option, bonus or other employee benefit plan, (ii)
in connection with the acquisition of another company's business by the Company
or any of its Subsidiaries (whether by acquisition of stock or assets, or by
merger, consolidation or other similar transaction) or the formation of a joint
venture, or (iii) pursuant to a registration statement on any form which limits
the amount of securities which may be registered by the issuer and/or selling
securityholders or is not available for registering the Shares held by the
Holders for sale to the public if and to the extent that such inclusion would
make use of such form unavailable (and no Shares owned by CHS or Affiliates are
being registered pursuant to such registration statement) (a "PIGGYBACK EVENT"),
the Company shall (at

                                       18
<Page>

least fifteen (15) days prior to the filing of such proposed registration
statement) notify each Holder of Executive Shares in writing of the proposed
registration statement, such notification to describe in detail the proposed
registration (including those jurisdictions where registration is required under
federal and/or state securities laws). If one or more of such Holders requests
the Company in writing, within ten (14) days of the receipt of such notification
from the Company, to include in such registration statement any of such Holder's
Executive Shares, then, subject to the remaining provisions hereof, the Company
will use its best efforts to include those Executive Shares in the registration
statement and to have the registration statement declared effective. Each such
request by a Holder of Executive Shares shall specify the number of Shares
intended to be offered and sold by each such Holder, shall express each such
Holder's present intent to offer such Shares for distribution, shall (subject to
the provisions of Section 7(b)); if the Company or CHS and its Affiliates has
not arranged for a plan of distribution or other marketing arrangements for such
distribution), describe the nature or method of the proposed offer and sale
thereof and shall contain the undertaking of each such Holder to provide all
such information and materials and take all such action as may be requested in
order to permit the Company to comply with all applicable requirements of the
SEC and to obtain acceleration of the effective date of such registration
statement. The Company, at its sole option, may elect not to proceed with the
registration statement which is the subject of such notice. The obligations of
the Company under this Section 7(a) are subject to the limitations, conditions
and qualifications set forth in Section 7(b). If an Executive decides not to
include or is precluded from including) all of his Executive Shares in any
registration statement thereafter filed by the Company, such Executive will
nevertheless continue to have the right, pursuant to this Section 7, to include
Executive Shares in future Piggyback Events, all upon the terms and subject to
the conditions as set forth in this Agreement. For purposes of this Section 7,
the phrase "Affiliates of the Company" shall not include CHS, the Company,
Beacon Operating or any of its Subsidiaries.

            (b)   Notwithstanding anything to the contrary herein contained, if
CHS's or its Affiliates' Shares are included in such registration statement,
each Holder of Executive Shares shall be entitled to include in such
registration statement (subject to the limitations and requirements set forth in
Section 7(c)) a whole number of Executive Shares up to the product of (i) the
number of Executive Shares then owned by such Holder and (ii) a fraction, the
numerator of which is the number of Shares held by CHS or its Affiliates (other
than the Company and its Subsidiaries) which are included in the contemplated
registration, and the denominator of which is the number of Shares then owned by
CHS or its Affiliates other than the Company and its Subsidiaries (it being
understood that this sentence shall require such piggyback registration, and
shall not be construed as an obligation by Company to use best efforts to cause
such registration).

            (c)   The obligation of the Company pursuant to Subsections 7(a) and
7(b) above are subject to each of the following limitations, conditions and
qualifications:

                  (i)     the Company shall be entitled to reduce the number of
     Executive Shares of any such Holder to be included in such registration if
     the managing underwriter(s) of a proposed public offering of the Company's
     securities advises the Company that, in its opinion, (or, if the offering
     is not underwritten, upon the Company's reasonable determination that)
     inclusion of all of such Holder's requested Shares would adversely affect
     the public offering of securities being sold by the Company so long as

                                       19
<Page>

     such reduction is proportionate to the reduction in the number of shares of
     CHS included in the offering.

                  (ii)    the Company shall use its best efforts to cause the
     registration statement to remain current (including the filing of necessary
     supplements or post-effective amendments) during the period commencing on
     the initial effective date of such registration statement and ending on the
     date on which such registration statement shall have remained effective for
     ninety (90) days;

                  (iii)   provided that the Company or CHS has not arranged for
     a plan of distribution and other marketing arrangements for such
     registration, it shall be a condition of the right of a Holder to
     participate that it shall have arranged for a plan of distribution of its
     Shares which are to be registered and made all pertinent marketing
     arrangements for such Shares. Any such plan and arrangements shall
     contemplate (i) a firm commitment underwriting or a best efforts
     underwriting, (ii) sales through a single broker-dealer (named in the
     registration statement as agent for such Holder pursuant to an agreement
     containing, without limitation, the agreement of such Holder not to offer
     or sell its Shares otherwise than through such broker-dealer unless and
     until such broker-dealer's authorization to sell the Shares has been
     terminated), or (iii) such other plan and arrangements as shall be approved
     by the Company. Notwithstanding the preceding sentence, if any securities
     to be sold by the Company or CHS pursuant to such registration statement
     are to be sold on a firm commitment basis through underwriters, those
     Holders desiring to sell their Shares in the offering shall, at the request
     of the Company or CHS, (i) sell their Shares on such basis through such
     underwriters and (ii) complete and execute all questionnaires, powers of
     attorney, indemnities, underwriting agreements and other documents
     consistent with the terms of this Agreement and reasonably required under
     the terms of such underwriting arrangements;

                  (iv)    the Company will furnish to each participating Holder
     such number of copies of any prospectus (including any preliminary or
     summary prospectus) as such Holder may reasonably request in order to
     effect the offering and sale of the Executive Shares to be offered and sold
     by such Holder, but only while the Company is required under the provisions
     hereof to cause the registration statement to remain current;

                  (v)     the Company shall include such qualification under
     applicable state securities laws as may be necessary to enable the Holders
     on whose behalf such registration is to be effected to offer and sell the
     Executive Shares which are the subject matter of their requests; provided,
     however, that the Company shall not be obligated to qualify as a foreign
     corporation to do business under the laws of any jurisdiction in which it
     is not then qualified or to file any general consent to service of process;

                  (vi)    all expenses incurred in connection with any
     registration or qualification pursuant to Section 7(a) or 7(b) above,
     including, without limitation, all SEC registration fees, state securities
     filing fees, printing expenses (excluding the printing of any agreements,
     memoranda or other documents pertaining solely to the sale of Executive
     Shares by Holders) and fees and disbursements of experts used by the
     Company in connection with such registration, shall, subject to
     requirements of any

                                       20
<Page>

     applicable regulatory agency, be borne by the Company. Each participating
     Holder (including CHS) shall bear the fees and disbursements of its own
     legal counsel, underwriting or brokerage discounts and commissions, and
     transfer taxes, on the sale of its Shares;

                  (vii)   the Company may require, as a condition to fulfilling
     its obligations under the registration provisions of Section 7(a) and 7(b)
     of this Agreement, receipt of executed customary indemnification agreements
     in form reasonably satisfactory to the Company from the Holders whose
     Shares are to be registered, and the Holders may require, as a condition to
     fulfilling their obligations under the registration provisions of Section
     7(a) and 7(b) of this Agreement, receipt of executed customary
     indemnification agreements from the Company and other participating holders
     of Shares in form reasonably satisfactory to the Holders whose Shares are
     to be registered;

                  (viii)  the Company shall notify each participating Holder at
     any time when a prospectus relating to such Shares is required to be
     delivered under the Act, of the happening of any event which causes such
     prospectus as then in effect to contain an untrue statement of a material
     fact or to omit to state a material fact required to be stated therein or
     necessary to make the statements therein not misleading, and, if necessary
     in the reasonable judgment of counsel for the Company, the Company will
     promptly prepare a supplement or amendment to such prospectus so that as
     thereafter delivered to the purchasers of such Shares, such prospectus will
     not contain any untrue statement of a material fact or omit to state a
     material fact necessary to make the statements therein not misleading;

                  (ix)    each participating Holder, upon receipt of any notice
     of the happening of any event of the kind described in Section 7(c)(viii)
     hereof, will immediately discontinue disposition of the Shares until such
     Holder's receipt of the copies of the supplemented or amended prospectus
     contemplated by Section 7(c)(viii) hereof or until such Holder is advised
     in writing by the Company that the use of the prospectus may be resumed,
     and, if so directed by the Company, such Holder will, or will request the
     managing underwriter or underwriters (if any) to, deliver to the Company
     all copies, other than permanent file copies then in such holder's
     possession, of the prospectus covering such Shares current at the time of
     receipt of such notice;

                  (x)     Executive agrees (i) to notify the Company as promptly
     as practicable of any inaccuracy or change in information previously
     furnished by such Holder to the Company or of the occurrence of any event,
     in either case, as a result of which any prospectus relating to such
     registration contains or would contain an untrue statement of a material
     fact regarding such Holder or omits or would omit to state any material
     fact regarding such Holder required to be stated therein or necessary to
     make the statements therein not misleading, and (ii) promptly to furnish to
     the Company any additional information required to correct and update any
     previously furnished information or required so that such prospectus shall
     not contain, with respect to such Holder, an untrue statement of a material
     fact or omit to state a material fact required to be stated therein or
     necessary to make the statements therein not misleading in light of the
     circumstances then existing; and

                                       21
<Page>

                  (xi)    for purposes of this Agreement, the phrases "best
     efforts" and "best efforts to cause," when used with reference to efforts
     to be made by a party hereto or any of its affiliates shall not require
     such party or any of its affiliates to pay or transfer any money, property
     or other thing of value, shall require such party and its affiliates to act
     with all reasonable promptness and dispatch with respect thereto and shall
     require the other party and its affiliates to act with all reasonable
     promptness and dispatch and to cooperate in all material respects with the
     first party's efforts in connection therewith.

            (d)   TRANSFER OF SHARES IN OPEN MARKET TRANSACTIONS. This Section
7(d) shall apply to any proposed Transfer of Shares by any Holder in an Open
Market Transaction during all such times as CHS and/or its Affiliates owns in
the aggregate greater than thirty percent (30%) of the Shares. During each
calendar quarter during which sales of Shares are permitted to be made in
accordance with agreements ("STANDSTILL AGREEMENTS") with the underwriters
engaged in connection with a Public Sale, and during each calendar quarter
following the termination of the Standstill Agreements, any such Holder that
desires to Transfer Shares may sell such number of Shares as equals his pro rata
share of one percent (1.0%) of the then outstanding Shares (or such lesser
percentage or number as maybe permitted by the Standstill Agreements). Fifteen
(15) business days prior to the beginning of each calendar quarter during which
sales of Shares are permitted under the Standstill Agreements, and fifteen (15)
days prior to each calendar quarter after the termination of the Standstill
Agreements, such Holder that desires to Transfer Shares shall deliver a written
notice to the Company setting forth the number of Shares that such Holder
desires to sell (up to such Holder's pro rata share of the aggregate quarterly
maximum specified above) in Open Market Transactions during the succeeding
quarter. If such Holder that is Transferring does not elect to sell his pro rata
share, the Company may allocate the right to sell such unused pro rata share to
any Stockholder of the Company. Within three (3) business days following the
beginning of each applicable quarter, the Company shall deliver a written notice
to such Holder that is Transferring setting forth the amount of Shares permitted
to be sold (as determined in accordance with this Section 7(d)) by such Holder
during such applicable calendar quarter in Open Market Transactions. The Company
may, in its discretion, from time to time increase the aggregate amount of
Shares which may be sold in any calendar quarter in Open Market Transactions.
Any Shares sold in an Open Market Transaction shall cease to be bound by the
terms and provisions of this Agreement. In addition to his pro rata share of one
percent (1%), each Holder may sell a proportionate amount of the Shares held by
such Holder equal to the proportionate amount of Shares sold by CHS in Open
Market Transactions in the public markets from time to time.

     8.     SALE OF THE COMPANY.

            (a)   If the holder(s) of a majority of the Shares then outstanding
and (if required under applicable law) the Board approve a Sale of the Company
(an "APPROVED SALE") (and if the Sale of the Company is to an entity that is an
Affiliate of CHS, the consideration for such Sale of the Company is fair to the
Company and the holders of Shares as determined pursuant to the same mechanism
used to determine Fair Market Value under Section 1), each Holder shall consent
to and raise no objections against the Approved Sale, and if the Approved Sale
is structured as a sale of Shares, each Holder shall, if requested by the
holder(s) of a majority of the Shares then outstanding, sell (or otherwise
Transfer) that percentage of his Executive Securities, on terms and conditions
approved by the Board (if necessary) and the

                                       22
<Page>

holder(s) of a majority of the Shares then outstanding, as shall equal the
percentage of Shares and other securities of the Company owned by CHS and any
Affiliate or successor of CHS that are to be included in such transaction. Each
Holder shall take all actions reasonably necessary or reasonably desirable (as
determined by the holder(s) of a majority of the Shares then outstanding) in
connection with the consummation of the Approved Sale. Without limiting the
foregoing, (i) if the Approved Sale is structured as a merger, consolidation,
joint venture or similar transaction, each Holder shall vote in favor of such
transaction and waive any dissenters' rights, appraisal rights or similar rights
in connection with such merger or consolidation, and (ii) if the Approved Sale
is structured as a sale or exchange of Shares, each Holder shall agree to sell
or exchange all of the Shares and Options held by such Holder on the terms and
conditions approved by the Board and the holders of a majority of the Shares
then outstanding: The Company shall use best efforts to notify Executive in
writing not less than thirty (30) days prior to the proposed consummation of an
Approved Sale (or, Participation Sale as described in Section 8(b) below);
PROVIDED that such Executive agrees that he or she will not, directly or
indirectly (without the prior written consent of the Company), disclose to any
other Person (other than to such Executive's legal counsel in confidence, as
otherwise necessary to protect such Executive's rights under this Agreement or
as otherwise required by law) any information related to such potential Sale of
the Company.

            (b)   If CHS proposes to sell to a purchaser or related group of
purchasers such number of Shares as equals or exceeds 50% of the then
outstanding Shares determined on a Fully-Diluted Basis (whether in one
transaction or a series of transactions) (a "PARTICIPATION SALE"), Executive may
elect to participate in the contemplated transaction by delivering written
notice to the Company and CHS within ten (10) days following the receipt by
Executive of notice of such transaction. Executive shall be entitled to sell, at
the same price and on the same terms as CHS, Shares equal to the product of (i)
the number of Shares owned by such Executive on a Fully-Diluted Basis multiplied
by (ii) the quotient of (x) the number of Shares sold by CHS in such transaction
divided by (y) the aggregate number of Shares held by CHS at such time, on a
Fully Diluted Basis. Notwithstanding anything to the contrary herein contained,
this Section 8(b) shall not apply to (x) any Sale to any officer, director,
employee, agent, or lender to the Company, Beacon Operating or any of its
Subsidiaries, or (y) any Sale or other Transfer to any successor CHS approved
fund or to any affiliate of CHS.

            (c)   If a Holder is required or elects to participate in an
Approved Sale or a Participation Sale pursuant to subsection (a) or (b) above:
(i) upon the consummation of the Approved Sale or the Participation Sale, as the
case may be, all of the Holders of Shares similarly situated shall receive the
same form and amount of consideration per Share, or if any Holders are given an
option as to the form and amount of consideration to be received, all such
Holders shall be given the same option; (ii) upon the consummation of the
Approved Sale or the Participation Sale, as the case may be, all of the holders
of Subordinated Notes similarly situated shall receive the same form and amount
of consideration in relation to the face amount of Subordinated Notes held by
such holders, or if any such holders are given an option as to the form and
amount of consideration to be received, all holders shall be given the same
option; and (iii) all Holders of then currently exercisable Options shall be
given an opportunity to either (A) exercise such rights prior to the
consummation of the Approved Sale or the Participation Sale, as the case may be,
and participate in such sale as Holders, or (B) upon the consummation of the
Approved Sale or the Participation Sale, as the case may be, receive in exchange
for such rights

                                       23
<Page>

consideration equal to the amount determined by multiplying (1) the same amount
of consideration per Share received by the Holders in connection with the
Approved Sale or the Participation Sale, as the case may be, less the exercise
price per share of such rights to acquire Shares, by (2) the number of Shares
represented by such rights. Without limiting the foregoing, any Holder
participating in a transaction pursuant to this Section 8 shall be required to
make such representations, warranties and covenants, and grant such
indemnification, as may be required by the purchaser of the Shares and which
have been made by CHS or the holders of a majority of the outstanding Shares, as
the case may be. Holders exercising rights under this Section 8(c) and 8(b)
shall be required to make such representations and warranties and grant such
indemnification as may be required by the purchaser of Shares and have been made
by CHS in such transaction.

            (d)   If the Board or the holders of a majority of the outstanding
Shares of the Company enter into any negotiation or transaction for which Rule
506 (or any similar rule then in effect) promulgated by the SEC under the 1933
Act may be available with respect to such negotiation or transaction (including
a merger, consolidation or other reorganization), each Holder shall, acting
together with other Holders, at the request of the Company, appoint a purchaser
representative (as such term is defined in Rule 501 under the 1933 Act)
reasonably acceptable to the Company. If Executive appoints a purchaser
representative designated by the Company, the Company shall pay the fees of such
purchaser representative, but if Executive declines to appoint the purchaser
representative designated by the Company, Executive shall appoint another
purchaser representative (reasonably acceptable to the Company), and Executive
shall be responsible for the fees of the purchaser representative so appointed.

            (e)   Each Holder shall bear such Holder's pro-rata share (based
upon the number of Shares sold on a Fully-Diluted Basis) of the costs of any
sale of Executive Securities pursuant to an Approved Sale or a Participation
Sale to the extent such costs are not otherwise paid by the Company or the
acquiring party; provided, however, that all Holders are treated on an equal
basis. Costs incurred by a Holder on such Holder's own behalf shall not be
considered costs of the transaction hereunder.

            (f)   Notwithstanding anything to the contrary contained in this
Agreement, the provisions of Section 8 shall terminate upon the consummation of
a Sale of the Company or a Public Offering.

     9.     LIMITED PREEMPTIVE RIGHTS.

            (a)   Except for the issuance of Shares or Options (A) in connection
with the acquisition of another Person's's business by the Company or any of its
Affiliates (whether by acquisition of stock or assets, or by merger,
consolidation or other similar transaction), the acquisition of any stock or
assets of any Person or the formation of a joint venture, (B) pursuant to a
Public Offering, (C) to current or future officers, employees, directors, agents
or consultants of the Company or its Subsidiaries, to Affiliates of the Company
(or any of their respective officers, directors, employees or agents) or to
holders of the existing securities of the Company (issued by the Company), or
(D) to the Company's or any Subsidiary's lenders in connection with the
incurrence, renewal or maintenance of indebtedness (including funded
indebtedness), if the Company authorizes the issuance and sale of any Shares
(other than as a dividend on the

                                       24
<Page>

outstanding Shares) or any Options, pursuant to the exercise of warrants or
otherwise, the Company shall first offer to sell to Executive a portion of such
Shares or Options equal to an amount determined by multiplying (x) the amount
obtained by dividing (1) the number of Executive Shares held by Executive
immediately prior to the proposed issuance of securities, on a Fully-Diluted
Basis, by (2) the aggregate number of Shares outstanding immediately prior to
the proposed issuance of such securities, on a Fully-Diluted Basis by (y) the
amount of such Shares or Options being issued in the transaction; provided that
Executive, if he is exercising his pre-emptive rights pursuant to this Section
9, shall, as a condition to such exercise, also be required to purchase the same
proportionate amount of any other securities that the purchasers of such Shares
or Options purchase in connection with the issuance of the securities subject to
the preemptive rights. Notwithstanding anything in this Section 9 to the
contrary, if preemptive rights arc exercised pursuant to this Section and
pursuant to the preemptive rights granted under the Executive Securities
Agreements and the Chief Executive Securities Agreements for an aggregate number
of Shares or Options which is greater than 100% of the Shares or Options to be
issued and sold by the Company, then the number of Shares that each executive,
including without limitation the Executive, shall be entitled to purchase
pursuant to such agreements shall be reduced, on a pro rata basis among all such
executives exercising preemptive rights under such agreements, to the extent
necessary such that the number of Shares and Options purchased pursuant to the
preemptive rights exercised under such agreements equal the number of Shares and
Options to be issued and sold by the Company.

            (b) Executive shall exercise Executive's pre-emptive rights
hereunder within fifteen (15) days following the receipt of written notice
from the Company describing in reasonable detail the purchase price, the
payment terms for the Shares or Options, the period in which the pre-emptive
right hereunder is to be exercised, and Executive's percentage allotment. The
Executive exercising the Executive's pre-emptive right shall execute all
documentation, and take all actions, as may be reasonably requested by the
Company in connection therewith.

            (c)   Upon the expiration of the offering period described above,
the Company shall be entitled to sell such Shares or Options which Executive has
not elected to purchase during the sixty (60) day period following such
expiration, on terms and conditions no more favorable to the purchasers thereof
than those offered to Executive. Any Shares or Options offered or sold by the
Company following such sixty (60) day period shall be reoffered to Executive
pursuant to the terms of this Section 9.

            (d)   The rights of the Executive under this Section 9 shall
terminate upon the earlier of (i) consummation of a Sale of the Company, or (ii)
the consummation of a Public Offering.

     10.    ELECTION OF DIRECTOR. Until the date of termination of the
employment of Executive with Beacon Operating and its Subsidiaries (for any
reason whatsoever), CHS shall vote all Shares owned by it, or where the Company
seeks to take action by written consent in lieu of a meeting of stockholders, to
execute written consents in lieu of such meeting of stockholders with respect to
such Shares, at such time as the election of the Board of Directors is
considered, for the election of Executive to serve as a member of the Board of
Directors, it being understood, however, that CHS shall control the Board of
Directors. Executive shall not be entitled to receive director's fees for his
service on the Board. The right to serve as a-director of the

                                       25
<Page>

Company is personal to Executive and Executive shall not be permitted to appoint
a designee to serve as his replacement as a director. Notwithstanding the
foregoing, the provisions of this Section 10 shall be of no further force and
effect immediately upon: (i) Executive's material breach of the Asset Purchase
Agreement dated as of August 21, 1997 between Seller, Beacon Operating and
stockholders of Seller, or (ii) any Closing Document (as defined in the Asset
Purchase Agreement), including without limitation, that certain Confidentiality
and Non-Competition Agreement between Executive and Beacon Operating of even
date herewith.

     11.    ADDITIONAL RESTRICTIONS ON TRANSFER.

            (a)   LEGEND. All certificates evidencing Executive Shares which are
subject to this Agreement shall bear the following legend:

     "THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
     SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT BE
     SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
     STATEMENT UNDER THE ACT OR AN EXEMPTION FROM REGISTRATION
     THEREUNDER. THE SHARES REPRESENTED HEREBY ARE ALSO SUBJECT TO
     ADDITIONAL RESTRICTIONS ON TRANSFER, CERTAIN REPURCHASE OPTIONS
     AND CERTAIN OTHER AGREEMENTS SET FORTH IN A CHIEF EXECUTIVE
     SECURITIES AGREEMENT BETWEEN BEACON HOLDING CORPORATION ("THE
     COMPANY") AND THE ORIGINAL HOLDER HEREOF DATED AS OF AUGUST 21,
     1997 AND THE COMPANY RESERVES THE RIGHT TO REFUSE THE TRANSFER OF
     THIS SECURITY UNTIL THE CONDITIONS THEREIN HAVE BEEN FULFILLED
     WITH RESPECT TO SUCH TRANSFER. A COPY OF SUCH AGREEMENT MAY BE
     OBTAINED BY THE HOLDER HEREOF AT THE COMPANY'S PRINCIPAL PLACE OF
     BUSINESS WITHOUT CHARGE."

If Executive Shares remain restricted following a Public Offering and the above

Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision or any other jurisdiction, and this Agreement shall be
reformed, construed and enforced in such jurisdiction so as to best give effect
to the intent of the parties under this Agreement.

            (b)   COMPLETE AGREEMENT. This Agreement, the Convertible Note and
the Subordinated Note executed concurrently herewith, collectively embody the
complete agreement and understanding among the parties and supersede and preempt
any prior understandings, agreements or representations by or among the parties,
written or oral, which may have related to the subject matter hereof in any way.

            (c)   COUNTERPARTS. This Agreement may be executed in separate
counterparts, each of which is deemed to be an original and all of which taken
together constitute one and the same agreement.

            (d)   SUCCESSORS AND ASSIGNS. Except as otherwise provided herein,
this Agreement shall bind and inure to the benefit of and be enforceable by
Executive, the Company, CHS and their respective legal representatives, heirs,

Securities hereunder.

            (e)   CHOICE OF LAW. This Agreement shall be governed and construed

law or conflict of law provision or rule (whether of the Commonwealth of

within the County of Cook in the State of Illinois for enforcement by the

entitled to enforce its rights under this Agreement specifically, to recover
damages and costs caused by any breach of any provision of this Agreement and to
exercise all other rights existing in such party's favor. In the event of a
dispute hereunder, the prevailing party's reasonable attorney's fees and costs
shall be reimbursed by the opposing party or parties in such dispute within
fourteen days following a judgment by a court or tribunal of competent

apply to any court of law or equity of competent jurisdiction (without posting
any bond or deposit) for specific performance and/or other injunctive relief in
order to enforce or prevent any violations of the provisions of this Agreement.

            (h)   WAIVER. The failure of any party to enforce any of the
provisions of this Agreement shall in no way be construed as a waiver of such
provisions and shall not affect the right of such party thereafter to enforce
each and every provision of this Agreement in accordance with its terms.

            (i)   BUSINESS DAYS. If any time period forgiving notice or taking
action hereunder expires on a day which is a Saturday, Sunday or legal holiday
in the state in which the Company's chief executive office is located, the time
period shall be automatically extended to the business day immediately following
such Saturday, Sunday or legal holiday.
