                         Breach or Restrictive Covenants

            SECTION 6.1. Majority Board Representation Upon Default.

            (a) In the event that KMOC fails to comply with the restrictive
covenants set forth in Section 7.1 of the Purchase Agreement and for so long as
such breach shall remain uncorrected. Holdings shall be entitled to nominate
such additional members to the KMOC Board necessary for the Holdings Directors
to constitute a majority of the KMOC Board. In connection therewith, the parties
hereto shall exercise all authority under applicable law to cause the authorized
number of directors of the KMOC Board to be increased to accommodate the

Holdings Nominee if such nominee is a non-administrative employee of The Beacon

to Section 6.1(a) shall terminate when the breach giving rise to such
entitlement has been cured by KMOC or Holdings ceases to be entitled to any
Holdings Nominees pursuant to Article II hereof; provided, however, that such
entitlement shall also cease in the event that Holdings fails to exercise its
good faith best efforts to cause the Holdings Directors to use their good faith
best efforts to cure the breach.

            (c) Holdings shall cause all additional Holdings Directors,
appointed or elected pursuant to Section 6.1(a) to resign immediately after KMOC
cures the breach giving rise to such appointment.

                                   ARTICLE VII
                                Tag Along Rights

            SECTION 7.1. Tag Along Offer. If at any time prior to an Initial
Public Offering, an Equity Holder and/or any of its affiliates (collectively.
the "Selling Holder") desires to sell KMOC Common Stock (i) representing more
than 5% of the shares of KMOC Common Stock outstanding to any one person in a
single transaction or in a series of related transactions or (ii) representing
more than 7.5% of the shares of KMOC Common Stock outstanding on a cumulative
basis of all sales made by such Equity Holder subsequent to the Effective Date
(but excluding sales which are subject to the preceding clause (i)), then prior
to the consummation of such sale (a "Sale") the Selling Holder shall provide
written notice (the "Tag Along Notice") of the proposed Sale to the other Equity
Holders (the "Tag Along Offerees") at least 45 days prior to the proposed date
of the Sale. The Tag Along Notice shall include:

            (a) The principal terms of the proposed Sale, including the number
of shares of KMOC Common Stock to be purchased from the Selling Holder, the
percentage such shares represent of the total number of shares of KMOC Common
Stock Beneficially Owned (on a fully diluted basis) by the Selling Holder (the
"Sale Percentage"), the purchase price and the name and address of the proposed
purchaser (the "Tag Along Purchaser"); and

            (b) An offer by the Selling Holder to include, at the option of each
Tag Along Offeree, in the Sale to the Tag Along Purchaser such number of shares
of KMOC Common Stock (not in any event to exceed the Sale Percentage of the
total number of shares of KMOC Common Stock held by such Tag Along Offeree)
owned by each Tag Along Offeree as determined in accordance with Section 7.2, on
the same terms and conditions, with respect to each share sold, as the Selling
Holder shall sell such of its shares. For purposes of determining the number of
shares of KMOC Common Stock that Holdings is entitled to sell in the sale and
under this Article VII ownership of the Holdings Warrants by Holdings Shall be
deemed to be ownership of the KMOC Common Stock underlying such Holdings
Warrants.


                                       12
<PAGE>

            SECTION 7.2. Exercise. Each Tag Along Offeree desiring to accept the
offer contained in the Tag Along Notice shall send a written commitment to the
Selling Holder specifying the number of shares of KMOC Common Stock (not in any
event to exceed the Sale Percentage of the total number of shares of Common
Stock Beneficially Owned (on a fully diluted basis) by such Tag Along Offeree)
which such Tag Along Offeree desires to have included in the Sale within thirty
(30) days after the effectiveness of the Tag Along Notice (each a "Participating
Seller"). Each Tag Along Offeree who has not so accepted such offer shall be
deemed to have waived all of its rights with respect to the Sale, and the
Selling Holder and the Participating Sellers, if any, shall thereafter be free
to sell to the Tag Along Purchaser, at a price no greater than the purchase
price set forth in the Tag Along Notice and otherwise on terms not more
favorable in any material respect to them than those set forth in the Tag Along
Notice, without any further obligation to such non-accepting Tag Along Offerees.
If, prior to consummation, the terms of such proposed Sale shall change with the
result that the price shall be greater than the maximum price set forth in the
Tag Along Notice or the other terms shall be more favorable to a Participating
Seller in any material respect than as set forth in the Tag Along Notice, it
shall be necessary for a separate Tag Along Notice to have been furnished, and
the terms and provisions of this Section 7 separately complied with, in order to
consummate such proposed Sale pursuant to this Section 7; provided, however,
that in the case of such a separate Tag Along Notice, the applicable period
referred to in Section 7.1 shall be 20 days and the applicable period referred
to above in this Section 7.2 shall be 15 days.

            The acceptance of each Participating Seller shall be irrevocable
except as hereinafter provided, and each such Participating Seller shall be
bound and obligated to sell its shares in the Sale, on the same terms and
conditions specified in the Tag Along Notice as the Selling Holder, such number
of shares of KMOC Common Stock as such Participating Seller shall have specified
in such Participating Seller's written commitment. In the event the Selling
Holder shall be unable to obtain the inclusion in the Sale of all shares of KMOC
Common Stock which the Selling Holder and each Participating Seller desires to
have included in the Sale (as evidenced in the case of the Selling Holder by the
Tag Along Notice and in the case of each Participating Seller by such
Participating Seller's written commitment) the number of shares to be sold in
the Sale by the Selling Holder and each Participating Seller shall be reduced on
a pro rata basis according to the Proportion which the number of shares which
each such Seller desires to have included in the Sale bears to the total number
of shares desired by all such Sellers to have included in the Sale.


                                       13

            If at the end of the ninetieth (90th) day following the date of the
effectiveness of the Tag Along Notice the Selling Holder has not completed the
Sale as provided in the foregoing provisions of this Section 7, each
Participating Seller shall be released from his or her obligations under his or
her written commitment, the Tag Along Notice shall be null and void, and it
shall be necessary for a separate Tag Along Notice to have been furnished, and
the terms and provisions of this Section 7 separately complied with, in order to
consummate such Sale pursuant to this Section 7, unless the failure to complete
such Sale resulted from any failure by any Tag Along Offeree to comply in any
material respect with the terms of this Section 7.

                                  ARTICLE VIII
                                Drag Along Rights

            SECTION 8.1. Drag Along. During the period commencing from the
Effective Date and ending on the later to occur of (i) the sixth anniversary of
the Effective Date or (ii) the date of an Initial Public Offering, each Equity
Holder hereby agrees, if requested by the other two Equity Holders ("Drag Along
Sellers"), to participate in a Transfer For Value (a "Drag Along Sale") of all
of the KMOC Common Stock and rights to acquire KMOC Common Stock Beneficially
Owned by each Equity Holder and its affiliates to any Person not affiliated with
any of the Drag Along Sellers (the "Drag Along Purchaser") in the manner and on
the terms set forth in this Section 8; provided, however, that the Drag Along
Sellers and their affiliates must collectively hold, on a fully diluted basis,
at least 20% of the outstanding common stock of KMOC in order to make a request
to cause a Drag Along Sale pursuant to this Article VIII.

            SECTION 8.2. Procedure. If the Drag Along Sellers elect to exercise
their rights under this Section 8, a notice (the "Drag Along Notice") shall be
furnished by the Drag Along Sellers to the other Equity Holder. The Drag Along
Notice shall set forth the principal terms of the Drag Along Sale, the purchase
price and the name and address of the Drag Along Purchaser. If the Drag Along
Sellers consummate the sale referred to in the Drag Along Notice, the Equity
Holder shall be bound and obligated to sell all of the shares of KMOC Common
Stock and rights to acquire KMOC Common Stock held by it and its affiliates in
the Drag Along Sale on the same terms and conditions. If at the end of the 90th
day following the date of the effectiveness of the Drag Along Notice the Drag
Along Sellers have not completed the Drag Along Sale, the Equity Holder shall be
released from its obligations under the Drag Along Notice, the


                                       14
<PAGE>

Drag Along Notice shall be null and void, and it shall be necessary for a
separate Drag Along Notice to have been furnished and the terms and provisions
of this Section 8 separately complied with, in order to consummate such Drag
Along Sale pursuant to this Section 8, unless the failure to complete such sale
resulted from any failure by the Equity Holder to comply in any material respect
with the terms of this Section 8.

                                   ARTICLE IX
                        Additional Transfer Restrictions

            SECTION 9.1. Transferee Voting Obligation. Except in connection with
a public offering of KMOC Common Stock, each Equity Holder hereby agrees not to
transfer shares of KMOC Common Stock or warrants to acquire KMOC Common Stock
unless the transferee of such shares or warrants agrees in writing to be bound,
to the same extent that such transferring Equity Holder is bound, by the
provision contained in Articles II, III, IV, V and VI of this Agreement and this
Section 9.1.

            SECTION 9.2. Transfer of Board Seats.

            (a) In connection with any transaction involving the transfer by
BFTC of at least the greater of (i) the BFTC Share Amount (as defined below) or
(ii) 4% or more of the then issued and outstanding KMOC Common Stock held by
BFTC (the greater of (a)(i) and (a)(ii) being the "BFTC Qualifying Amount"),
BFTC may transfer to such transferee one of the nominees BFTC is entitled to
nominate pursuant to Article IV hereof for each BFTC Qualifying Amount of shares
of KMOC Common Stock acquired by such transferee in such transaction; provided,
however, that such transferee shall be entitled to appoint a nominee only for so
long as such transferee holds more than the BFTC Qualifying Amount of shares of
KMOC Common Stock for each nominee to which such transferee is entitled pursuant
to such transfer.

            (b) In connection with any transaction involving the transfer by
Holdings of at least the greater of (i) the Holdings Share Amount (as defined
below) or (ii) 6% or more of the then issued and outstanding KMOC Common Stock
held by Holdings (the greater of (b)(i) and (b)(ii) being the "Holdings
Qualifying Amount"), Holdings may transfer to such transferee one of the
nominees Holdings is entitled to nominate pursuant to Article II hereof for each
Holdings Qualifying Amount of shares of KMOC Common Stock acquired by


                                       15
<PAGE>

such transferee in such transaction. For purposes of the preceding sentence, in
the event of a transfer of Holdings Warrants, the KMOC Common Stock underlying
such Holdings Warrants shall be treated as a transfer of KMOC Common Stock;
provided, however, that in the case where Holdings Warrants are transferred by
Holdings, the transferee shall not be entitled to appoint a nominee until such
transferee exercises its Holdings Warrants acquired from Holdings such that the
total number of shares of KMOC Common Stock actually held (and not including any
KMOC Common Stock underlying any unexercised Holdings Warrants) by such
transferee equals at least the Holdings Qualifying Amount for each nominee to
which such transferee is entitled pursuant to such transfer; and provided
further, that such transferee shall be entitled to appoint a nominee only for so
long as such transferee holds more than the Holdings Qualifying Amount of shares
of KMOC Common Stock (and not including any KMOC Common Stock underlying any
unexercised Holdings Warrants) for each nominee to which such transferee is
entitled pursuant to such transfer.

            (c) The term "BFTC Share Amount" shall mean an amount of shares
equal to 16,667 shares of KMOC Common Stock held by BFTC as adjusted for any
stock split, stock dividend, reverse stock split or other similar transaction or
dilution. The term "Holdings Share Amount" shall mean an amount of shares equal
to 25,000 shares of KMOC Common Stock held by Holdings as adjusted for any stock
split, stock dividend, reverse stock split or other similar transaction or
dilution.

            SECTION 9.3. Right of First Offer.

            (a) During the period commencing from the date hereof and ending on
the date of an Initial Public Offering of KMOC Common Stock, if BFTC desires to
sell shares of KMOC Common Stock other than pursuant to an Initial Public
Offering, Articles VII or VIII hereof or pursuant to existing tag along or drag
along provisions to which BFTC may be subject. BFTC shall first give written
notice (a "Transfer Notice") to KMOC, Waldo and each Original Noteholder
containing (i) the number of shares of KMOC Common Stock proposed to be
transferred (the "Offered Shares"), (ii) the purchase price (the "First Offer
Price") which BFTC proposes to be paid for the Offered Shares, and (iii) an
offer to sell all of the Offered Shares in the following order of priority:
first to KMOC; then, if and to the extent that KMOC does not elect to purchase
all of the Offered Shares, pro rata to each Original Noteholder on the basis of
the Principal amount of Investor Notes held by such Original Noteholder; and
lastly,


                                       16
<PAGE>

to Waldo to the extent that there remain Offered Shares which neither KMOC nor
the Original Noteholders elect to purchase.

            (b) KMOC, Waldo and the Original Noteholders (collectively. the
"Offerees") shall have a period of 30 days after the date of receipt of the
Transfer Notice (the "Response Period") to accept the offer made pursuant to the
Transfer Notice to purchase all of the Offered Shares at the First Offer Price
by delivering written notice of acceptance to BFTC within the Response Period;
provided, however, that in order for this option to be deemed exercised prior to
the end of the Response Period, BFTC shall have received acceptances from the
Offerees (the "Accepting Offerees") to purchase shares which in the aggregate
must be greater than or equal to the number of shares offered for sale in the
Transfer Notice.

            (c) The closing of the sale of the Offered Shares will be held at
KMOC's principal office in New York on a date mutually agreed upon by the
Accepting Offerees and BFTC which is not less than 10 days nor more than 50 days
after the end of the Response Period. At the closing, the Offerees will deliver
the consideration in accordance with the terms of the offer set forth in the
Transfer Notice, and BFTC will deliver the Offered Shares to the Offerees, duly
indorsed for transfer, free and clear of all liens, claims and encumbrances.

            (d) If, at the end of the Response Period, the Offerees have not
given notice of their decision to purchase all of the Offered Shares, then BFTC
shall be entitled for a period of 90 days beginning the day after the expiration
of the Response Period to sell the Offered Shares at a price not lower than the
First Offer Price and on terms not more favorable to the transferee than were
contained in the Transfer Notice. Promptly after any sale pursuant to this
Section 9.3, BFTC shall notify KMOC of the consummation thereof and shall
furnish such evidence of the completion (including time of completion) of such
sale and of the terms thereof as KMOC may request.

            (e) If, at the end of any such 90-day period provided for in this
Section 9.3, BFTC has not completed the sale of the Offered Shares, BFTC shall
no longer be permitted to sell any of such Offered Shares pursuant to this
Section 9.3 without again fully complying with the provisions of this Section
3.2 and all the restrictions on sale, transfer, assignment or other disposition
contained in this Agreement shall again be in effect.


                                       17
<PAGE>

            (f) Notwithstanding the foregoing, in the event that the Accepting
Offerees fail to close the purchase of all of the Offered Shares on the date
mutually agreed upon by the Accepting Offerees and BFTC, BFTC shall be entitled,
for a period of 120 days from the closing date originally agreed upon, to sell
the Offered Shares at any reasonably negotiated price to any third party without
having to further comply with the provisions of this Section 9.3; provided,
however, that if the failure to close the purchase of all of the Offered Shares
on the date mutually agreed upon by the Accepting Offerees and BFTC was due to
the failure of an Accepting Offeree to close the purchase of the amount of
Offered Shares it agreed to purchase pursuant to Section 9.3(b), the other
Accepting Offerees may allocate among themselves, in the order of priority set
forth in Section 9.3(a)(iii), such remaining Offered Shares for which financing
was not obtained and shall have a period of 10 additional days from the
originally agreed upon closing date to effectuate the purchase of all of the
Offered Shares before the provisions of this Section 9.3(f) shall apply.

            SECTION 9.4. Exercise of BFTC Demand Rights. BFTC hereby agrees not
to exercise its demand registration rights to cause a registration of KMOC
Common Stock pursuant to Section 2.1(a) of the Shareholder Rights Agreement,
dated as of February 10, 1997, between KMOC and BFTC, unless either (i) in
connection with such registration and sale of KMOC Common Stock held by BFTC all
of the outstanding Investor Notes shall have been paid in full or (ii) prior to
such registration and sale of KMOC Common Stock held by BFTC all of the Investor
Notes have been paid in full.

Agreement which shall terminate on an earlier date as expressly provided herein,

of the outstanding shares of KMOC common stock and Holdings shall no longer be
entitled to any Holdings Nominees pursuant to Section 2.1 hereof.

herein shall not be in any way impaired thereby, it being intended that all of
the rights and privileges of the parties hereto shall be enforceable to the
fullest extent permitted by law.

            SECTION 11.5. Counterparts. This Agreement may be executed in two or
more counterparts, each of which shall be deemed an original and all of which
shall, taken together, be considered one and the same agreement, it being
understood that all parties need not sign the same counterpart.

            SECTION 11.6. Entire Agreement; No Third Party Beneficiaries. This
Agreement (a) constitutes the entire agreement and supersedes all prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter hereof and (b) is not intended to confer upon any
Person, other than the parties hereto, any rights or remedies hereunder.

            SECTION 11.7. Further Assurances. Each party shall execute, deliver,
acknowledge and file such other documents and take such further actions as may
be reasonably requested from time to time by the other party hereto to give
effect to and carry out the transactions contemplated herein.

            SECTION 11.8. Governing Law; Equitable Remedies. This Agreement
shall be governed by and construed in accordance with the laws of the State of
Delaware, regardless of the laws that might otherwise govern under applicable
principles of conflicts of law. The parties hereto agree that irreparable damage
would occur in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached. It
is accordingly agreed that the parties hereto shall be entitled to equitatable
relief, including in the form of injunctions, in order to enforce specifi-


                                       21

cally the provisions of this Agreement, in addition to any other remedy to which
they are entitled at law or in equity.

            SECTION 11.9. Amendments; Waivers.

            (a) No provision of this Agreement may be amended or waived unless
such amendment or waiver is in writing and signed, in the case of an amendment,
by the parties hereto, or in the case of a waiver, by the party against whom the
waiver is to be effective.

            (b) No failure or delay by any party in exercising any right, power
or privilege hereunder shall operate as waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
provided shall be cumulative and not exclusive of any rights or remedies
provided by law.

            SECTION 11.10. Assignment. Neither this Agreement nor any of the
rights or obligations hereunder shall be assigned by either of the parties
hereto without the prior written consent of the other party, except that either
party may assign all its rights and obligations to the assignee of all or
substantially all of the assets of such party including an acquisition through
merger, provided that such party shall in no event be released from its
obligations hereunder without the prior written consent of the other party.
Subject to the preceding sentence, this Agreement will be binding upon, inure to
the benefit of and be enforceable by the parties and their respective successors
and assigns. Any attempted assignment in contravention hereof shall be null and
void.
