office Regular Directors consisting solely of the following:

                (A)          such number of designees of the Partnerships
                             equal in the aggregate to (x) the total number of
                             Regular Directors, minus (y) the number of
                             directors, if any, to be elected in accordance
                             with clause (C) below, minus (z) one (in the
                             event the Blackstone Investors shall have
                             designated and not withdrawn the designation of
                             an Additional Director in accordance with Section
                             2.2) PROVIDED, this designation right of the
                             Partnerships shall terminate if the Partnerships
                             and its Affiliates collectively own less than 10%
                             of the Common Stock on a fully diluted basis;

                (B)          any Additional Director designated by the
                             Blackstone Investors pursuant to Section 2.2; and

                (C)          in the event all of the Class B Common Stock
                             shall have been reclassified or converted into or
                             otherwise exchanged for Class A Common Stock,
                             such number of designees of the Blackstone
                             Investors equal to 50% of the total number of

<PAGE>   8
                                                                               6





                             directors comprising the Board, rounded upward,
                             if necessary, to the nearest whole number.

                  (c) The Partnerships agree that they shall designate for
election to the Board out of their "allotment" in accordance with subparagraph
(A) above the chief executive officer of the Company and/or such other officer
or officers as shall be mutually agreed upon by the Partnerships and the
Blackstone Investors. The Partnerships further agree that in accordance with
subparagraph (A) above they shall also designate out of their "allotment" for
election to the Board as "independent directors" up to two individuals selected
by the Board's nominating committee to the extent the election of such
independent directors is necessary in connection with the listing or inclusion
of any class of the Company's securities on a national securities exchange or in
the NASDAQ national market system.

                  (d) If the Blackstone Investors or the Partnerships shall
notify the other of their desire to remove, with or without cause, any director
of the Company previously designated by such Stockholder (other than an officer
or independent director designated pursuant to subsection (c) above), each
Stockholder shall vote (to the extent eligible to vote) all of the Common Stock
beneficially owned or held of record by it or him so as to remove such director
or, upon request, each Stockholder shall promptly execute and return to the
Company any written resolution relating thereto. For purposes of this subsection
(d) and subsection 2.1(e), the Additional Director shall be deemed designated by
the Blackstone Investors.

                  (e) If any director previously designated by the Blackstone
Investors or the Partnerships ceases to serve on the Board (whether by reason of
death, resignation, removal or otherwise), the Stockholder who designated such
director shall be entitled to designate a successor director to fill the vacancy
created thereby, and each Stockholder shall vote (to the extent eligible to
vote) all of the Common Stock beneficially owned or held of record by it or him
in favor of such designation or, upon request, each Stockholder shall promptly
execute and return to the Company any written resolution relating thereto.
Notwithstanding the foregoing, in the event an officer or independent director
designated pursuant to clause (c) above ceases to serve on the Board, a
successor director shall be identified in the same manner the director who so
ceased to serve was selected, and each Stockholder shall take such actions to
elect such successor to the Board as is specified in the preceding sentence.

                  2.2 ADDITIONAL DIRECTOR . Notwithstanding any other provision
of this Agreement, at any time at the request of the Blackstone Investors the
number of directors that may be designated by the Partnerships as provided above
shall be reduced by one, and the Blackstone Investors shall have the right to
designate one additional individual for election to the Board as a Regular
Director (the "ADDITIONAL DIRECTOR"). If such request


<PAGE>   9
                                                                               7



is made other than in connection with the annual election of directors, the
Partnerships shall cause one of their prior designees (as selected by the
Partnerships) immediately to resign from the Board in order that the Additional
Director may immediately replace such resigning director. The foregoing
provisions shall remain in effect continuously until such time as the Blackstone
Investors shall provide written notice to the Company and the other parties
hereto that the right to designate an Additional Director shall be suspended.
The temporary suspension at the option of the Blackstone Investors of such right
to designate an Additional Director shall in no way impair the right of the
Blackstone Investors subsequently to designate another Additional Director
pursuant to this Section 2.2.

                  3.1 LIMITATIONS ON TRANSFER. (a) Each Stockholder hereby
agrees that, except for Transfers effected by a Stockholder pursuant to an

substance reasonably satisfactory to the Company of counsel reasonably
satisfactory to the Company that such Transfer is exempt from or not subject to
the provisions of Section 5 of the Securities Act and any other applicable
securities laws.

                  (b) Each Stockholder hereby agrees that, except for Transfers
in connection with a Public Offering, Transfers pursuant to Rule 144 under the
Securities Act, Transfers to the Company in one or more transactions approved by
the Board of Directors of the Company and Transfers pursuant to Sections 3.5
(tag-along transfers) and 3.6 (drag-along transfers), no Transfer shall occur
unless the transferee shall agree in a writing reasonably satisfactory in form
and substance to the Company to become a party to, and be bound to the same
extent as its transferor by the terms of, this Agreement.

                  (c) Notwithstanding anything contained herein to the contrary,

than $60 million net cash proceeds in the aggregate from one or more sales or
other dispositions of Common Stock and (ii) in compliance with Rule 144 under

                  (d) The Partnerships shall implement partnership arrangements
satisfactory to the Blackstone Investors whereby the partners of the
Partnerships shall not be permitted to Transfer their partnership interests in a
manner that circumvents the provisions of this Section 3.

                  3.2 TRANSFERS TO AFFILIATES. Notwithstanding anything
contained herein to the contrary, but subject to compliance with applicable
securities laws, each of the Blackstone Investors, the Veritas Investors and the
Management Stockholders shall be entitled, from time to time, to Transfer any or
all of the shares of Common Stock beneficially owned by him or it to any of his
or its Affiliates who agree in a writing reasonably satisfactory in form and
substance to the Company to become a party to, and be bound to the same extent
as its transferor by the terms of, this Agreement. Any Transfer by a Blackstone
Investor or any of its Affiliates to any of its stockholders (or other equity
owners) of any or all of the shares of Common Stock beneficially owned by it
(including a distribution of such shares of Common Stock upon a liquidation of a
Blackstone Investor or any of its Affiliates or otherwise) shall be deemed to be
a Transfer to an Affiliate of a Blackstone Investor for purposes of this Section
3.2.

                  3.3 EFFECT OF VOID TRANSFERS. In the event of any purported
Transfer of any shares of Common Stock in violation of the provisions of this

                  3.5 TAG-ALONG RIGHTS. (a) So long as this Agreement shall
remain in effect and the Blackstone Investors, their respective Affiliates and
the Partnerships beneficially own, collectively, on a fully diluted basis an
aggregate number of shares of Common Stock not less than 25% of the Common Stock
then outstanding, with respect to any proposed Transfer by a Blackstone Investor
(in such capacity, a "Transferring Stockholder") of Common Stock permitted
hereunder (with respect to Common Stock held directly or as a Class B Asset of a
Partnership), other than (i) as provided in Section 3.2 (transfers to
Affiliates), (ii) in a Public Offering or (iii) pursuant to Rule 144, the
Transferring Stockholder shall have the obligation, and the Partnerships (with
respect to Common Stock held as a Class A Asset), the Veritas Investors, the
Trustee, each of the Management Stockholders and their respective Permitted
Transferees (the "Tagging Stockholders") shall have the right, to require the
proposed transferee to purchase from each of such Tagging Stockholders a number
of shares of Common Stock up to the product (rounded up to the nearest whole
number) of (i) the quotient determined by dividing (A) the aggregate number of
shares of Common Stock owned by such Tagging Stockholder by (B) the aggregate
number of shares of Common Stock owned by the Transferring Stockholder and the
Tagging Stockholders, and (ii) the total number of shares of Common Stock
proposed to be directly or indirectly Transferred to the transferee in the
contemplated Transfer, and at the same price per share of Common Stock and upon
the same terms and conditions (including, without limitation, time of payment
and form of consideration) as to be paid and given to the Transferring
Stockholder; PROVIDED, that in order to be entitled to exercise his or its right
to sell shares of Common Stock to the proposed transferee pursuant to this
Section 3.5, each Tagging Stockholder must agree to make to the Transferee
substantially the same representations, warranties, covenants, indemnities and
agreements as the Transferring Stockholder agrees to make in connection with the
proposed Transfer of the shares of Common Stock of the Transferring Stockholder;
and PROVIDED FURTHER that the tag-along rights and obligations set forth in this
Section 3.5 shall not be applicable unless prior to the proposed Transfer by the
Transferring Stockholder, the Blackstone Investors shall have previously
realized not less than $60 million net cash proceeds in the aggregate from one
or more sales or other dispositions of Common Stock; and PROVIDED, FURTHER that,
if (x) prior to such proposed Transfer the Blackstone Investors shall have
previously realized less than $60 million of net cash proceeds in the aggregate
from one or more sales or other dispositions of Common Stock and (y) 

<PAGE>   12
                                                                              10




after such proposed Transfer the Blackstone Investors are reasonably expected to
have realized (in the aggregate, together with all previous Transfers) in excess
of $60 million of net cash proceeds from one or more sales or other dispositions
of Common Stock (the amount of such excess, the "Incremental Taggable Amount"),
then the Tagging Stockholders shall have the right to require the proposed
transferee to purchase such number of shares of Common Stock pursuant to this
Section 3.5 calculated as if the Transferring Stockholder was proposing to sell
only the number of shares of Common Stock that would yield the Incremental
Taggable Amount.

                  (b) The Transferring Stockholder shall give notice to each
Tagging Stockholder of each proposed Transfer giving rise to the rights of such
Tagging Stockholder set forth in the first sentence of Section 3.5(a) at least
10 Business Days prior to the proposed consummation of such Transfer, setting
forth the number of shares of Common Stock proposed to be so transferred, the
name and address of the proposed transferee, the proposed amount and form of
consideration (and if such consideration consists in part or in whole of
property other than cash, the Transferring Stockholder shall provide such
information, to the extent reasonably available to the Transferring Stockholder,
relating to such consideration as the Tagging Stockholder may reasonably request
in order to evaluate such non-cash consideration) and other terms and conditions
of payment offered by the proposed transferee, and a representation that the
proposed transferee has been informed of the tag-along rights provided for in
this Section 3.5 and has agreed to purchase shares of Common Stock in accordance
with the terms hereof. The Transferring Stockholder shall deliver or cause to be
delivered to each Tagging Stockholder copies of all transaction documents
relating to the proposed Transfer (including draft and final versions of such
documents) as the same become available. The tag-along rights provided by this
Section 3.5 must be exercised by each Tagging Stockholder within 8 Business Days
following receipt of the notice required by the preceding sentence, by delivery
of a written notice to the Transferring Stockholder indicating the desire of
such Tagging Stockholder to exercise its or his rights and specifying the number
of shares of Common Stock it or he desires to sell. The Transferring Stockholder
shall be entitled under this Section 3.5 to Transfer to the proposed transferee
the number of shares of Common Stock calculated in accordance with Section
3.5(a).

                  (c) If any Tagging Stockholder exercises its or his rights
under Section 3.5(a), the closing of the purchase of the Common Stock with
respect to which such rights have been exercised shall take place concurrently
with the closing of the sale of the Transferring Stockholder's Common Stock.

                  3.6 DRAG-ALONG RIGHTS. (a) So long as this Agreement shall
remain in effect and the Blackstone Investors and their Affiliates beneficially
own, collectively, on a fully diluted basis an aggregate number of shares of
Common Stock not less than 20% of the Common Stock then outstanding, if any of
the

                                       11




Blackstone Investors receives a bona fide offer from a Person other than a
Blackstone Investor or any of its Affiliates (a "Third Party") to purchase in an
arms'-length transaction all, but not less than all, of the outstanding shares
of Common Stock owned by the Stockholders (other than the Trustee) and such
offer is accepted by such Blackstone Investor, then each Stockholder (other than
the Trustee) hereby agrees that it or he will Transfer all shares of Common
Stock owned by it or him to such Third Party on the terms of the offer so
accepted by such Blackstone Investor, including the same per share
consideration.

                  (b) The Transferring Stockholder shall give notice (the
"Drag-Along Notice") to each of the other Stockholders (other than the Trustee)
of any proposed Transfer giving rise to the rights of such Transferring
Stockholder set forth in Section 3.6(a) as soon as practicable following the
acceptance of the offer referred to in Section 3.6(a). The Drag-Along Notice
shall set forth the number of shares of Common Stock proposed to be so
Transferred, the name of the proposed transferee, the proposed amount and form
of consideration (and if such consideration consists in part or in whole of
property other than cash, the Transferring Stockholder shall provide such
information, to the extent reasonably available to the Transferring Stockholder,
relating to such consideration as the Tagging Stockholder may reasonably request
in order to evaluate such non-cash consideration) and the other terms and
conditions of the offer. The Transferring Stockholder shall notify the
Partnerships at least 3 weeks in advance of entering into a definitive agreement
in connection with such offer if Stockholders will be required to sign any
agreement containing representations, warranties and indemnities and will
provide in advance to one counsel acting for the Partnerships and the other
Stockholders subject to the Drag- Along Notice (which counsel shall be other
than counsel for the Transferring Stockholder) a copy of the representations,
warranties and indemnities proposed to be made by such Stockholders. In any such
agreement such Stockholders will be required to make the same representations,
warranties and indemnities as the Transferring Stockholder so long as they are
made severally and not jointly. The Company shall pay the fees and expenses of
counsel for the Partnerships and the other Stockholders (other than the Trustee)
as well as counsel for the Blackstone Investors in connection with any
transaction referred to in this Section 3.6. If the Transfer referred to in the
Drag- Along Notice is not consummated within 120 days from the date of the
Drag-Along Notice, the Transferring Stockholder must deliver another Drag-Along
Notice in order to exercise its rights under this Section 3.6 with respect to
such Transfer or any other Transfer.

                  3.7 PIGGYBACK RIGHTS. (a) Each time the Company is planning to
file a registration statement under the Securities Act (other than a
registration statement on Form S-4 or S-8 or any similar or successor form) in
connection with the proposed offer and sale of Common Stock (or other equity
securities) for the account of the Company or any securityholder of the Company
exercising a contractual right to cause the Company to file such 

<PAGE>   14
                                                                              12



registration statement (the "INITIATING PARTY"), the Company will give prompt
written notice thereof to each of the Blackstone Investors, the Partnerships,
the Veritas Investors, the Trustee and the Management Stockholders regarding the
rights of such parties (collectively, the "NON-INITIATING PARTIES") under this
Section 3.7, at least 10 Business Days prior to the anticipated filing date of
such registration statement. Upon the written request of any member of the
Non-Initiating Parties made within 8 Business Days after the receipt of any such
notice from the Company, which request shall specify the shares of Common Stock
(the "PIGGY-BACK SHARES") intended to be disposed of by such member in such
offering, the Company will use its reasonable best efforts to effect the
registration under the Securities Act of all Piggy-Back Shares which the Company
has been so requested to register by such Persons to the extent required to
permit the disposition of the Piggy-Back Shares to be registered; PROVIDED, that
(i) if, at any time after giving written notice of its intention to register any
Common Stock and prior to the effective date of the registration statement filed
in connection with such registration, the Initiating Party shall determine for
any reason not to proceed with the proposed registration, the Company may at its
election give written notice of such determination to each holder of Piggy-Back
Shares and thereupon shall be relieved of its obligation to register any
Piggy-Back Shares in connection with such registration, and (ii) if such
registration involves an underwritten offering, each holder of Piggy-Back Shares
requesting to be included in the Company's registration must sell its shares to
the underwriters on the same terms and conditions as apply to the Initiating
Parties. Notwithstanding anything in this Agreement to the contrary, the rights
and obligations set forth in this Section 3.7 shall not be applicable to the
Partnerships with respect to their Class A Assets, the Veritas Investors and the
Management Stockholders unless, prior to the proposed offer and sale of Common
Stock by the Initiating Party, the Blackstone Investors shall have previously
realized not less than $60 million net cash proceeds in the aggregate from one
or more sales of Common Stock; PROVIDED that, if (x) prior to such proposed
offer and sale the Blackstone Investors shall have previously realized less than
$60 million of net cash proceeds in the aggregate from one or more sales of
Common Stock and (y) after such proposed offer and sale the Blackstone Investors
are reasonably expected to have realized (in the aggregate, together with all
previous transfers) in excess of $60 million of net cash proceeds from one or
more sales of Common Stock (the amount of such excess, the "Incremental
Piggy-Back Amount"), then the Non- Initiating Parties shall have the right to
offer and sell such number of shares of Common Stock pursuant to this Section
3.7 calculated as if the Initiating Party was proposing to offer and sell only
the number of shares of Common Stock that would yield the Incremental Piggy-Back
Amount.

                  (b) If a registration pursuant to this Section 3.7 involves an
underwritten offering and the managing underwriter or underwriters in good faith
advise the Company in writing that, in their opinion, the number of shares of
Common Stock which the Initiating Party, the holders of Piggy-Back Shares and
any other 


<PAGE>   15
                                                                              13



Persons intend to include in such registration exceeds the largest number of
shares of Common Stock which can be sold in such offering without having an
adverse effect on such offering (including, but not limited to, the price at
which the shares of Common Stock can be sold), then the Company will include in
such registration (i) first, 100% of the shares of Common Stock the Initiating
Party proposes to sell for its own account, and (ii) second, to the extent that
the number of shares of Common Stock which the Initiating Party proposes to sell
is less than the number of shares of Common Stock which the Initiating Party has
been advised can be sold in such offering without having the adverse effect
referred to above, the number of outstanding shares of Common Stock to be
included in such offering will be determined on the basis of the relative
percentage relationships of (v) the number of outstanding shares of Common Stock
to be included by any of the Blackstone Investors and their respective
Affiliates (either directly or through the Partnerships), (w) the number of
outstanding shares of Common Stock to be included by the Partnerships (with
respect to Common Stock held as a Class A Asset) and the Veritas Investors, (x)
the number of outstanding shares of Common Stock to be included by the Trustee,
(y) the number of outstanding shares of Common Stock to be included by the
Management Stockholders and their Affiliates and (z) the number of outstanding
shares of Common Stock to be included by any other Persons who are entitled to
include shares of Common Stock in such offering.

                  3.8 DEMAND REGISTRATIONS. (a) Provided the Blackstone
Investors collectively own, directly or indirectly through the Partnerships as
Class B Assets, at least 5% of the Common Stock on a fully diluted basis, upon
the written request from time to time (a "REQUEST") of any Blackstone Investor
or any Affiliate of a Blackstone Investor that holds Common Stock that the
Company effect the registration under the Securities Act of all or part of the
shares of Common Stock owned by such Blackstone Investors and Affiliates,
directly or indirectly through the Partnerships as Class B Assets, the Company
will as expeditiously as practicable use its reasonable best efforts to effect
the registration under the Securities Act of such shares and cause such
registration statement to remain effective for a period of not less than 180
days; PROVIDED, HOWEVER, that the Company shall not be required to effect more
than three effective registrations pursuant to this Section 3.8(a).

                  (b) If (i) the Blackstone Investors shall have previously
realized at least $45 million of net cash proceeds from the sale of Common Stock
in one or more transactions yielding at least a 20% compounded annualized
internal rate of return on the entire initial investment by them (without
ascribing any value to any remaining shares of Common Stock held by the
Blackstone Investors), (ii) the Blackstone Investors have not sold any shares of
Common Stock, either directly or through the Partnerships, within the preceding
nine month period and (iii) the Partnerships own at least 5% of the outstanding
Common Stock on a fully-diluted basis, then the Partnerships shall have the
right to make one written request ("Partnerships' Request") 


<PAGE>   16
                                                                              14




to the Company that the Company effect the registration under the Securities Act
of all or part (constituting not less than 5% of outstanding shares) of the
shares of Common Stock owned by the Partnerships, whereupon the Company will as
expeditiously as practicable use its reasonable best efforts to effect the
registration under the Securities Act of such shares and cause such registration
statement to remain effective for a period of not less than 180 days. In
addition, if the Blackstone Investors no longer have any right to make a Request
pursuant to Section 3.8(a), then the Partnerships shall have the right to make
one additional Partnerships' Request pursuant to this Section 3.8(b) (without
regard to clauses (i), (ii) and (iii)).

                  3.9 OTHER REGISTRATION-RELATED MATTERS. (a) Each Stockholder
agrees that it shall not effect any sales of Common Stock or securities
convertible into or exercisable or exchangeable for Common Stock during the 14
days prior to and up to a 180 day period beginning on the effective date of a
registration statement relating to an underwritten public offering of Common
Stock (whether pursuant to Section 3.7 or 3.8 or otherwise, except as part of
such registration) if and to the extent reasonably requested in writing (with
reasonable prior written notice) by the managing underwriter of the underwritten
public offering or by the Company on their behalf.

                  (b) The Company agrees not to effect any sales of Common Stock
or securities convertible into or exercisable or exchangeable for Common Stock

connection with an underwritten public offering of Common Stock, if and to the
extent reasonably requested in writing (with reasonable prior written notice) by
the managing underwriter of the underwritten public offering except in
connection with the conversion or exercise of previously outstanding options,
warrants or other rights.

                  (c) The Company may require any Person that is selling shares
of Common Stock in a Public Offering pursuant to Section 3.7 or 3.8 to furnish
to the Company in writing such information regarding such Person and the
distribution of the shares of Common Stock which are included in a Public
Offering as may from time to time reasonably be requested in writing in order to
comply with the Securities Act.

                  (d) The Company will pay all Registration Expenses in
connection with each registration or proposed registration of Common Stock
pursuant to Section 3.7 or 3.8.

                  (e) Before filing a registration statement or prospectus, or

                  (f) The Company will furnish to each seller of Common Stock
such number of copies of the applicable registration statement and of each
amendment or supplement thereto (in each case including all exhibits), such

disposition in such jurisdictions of the Common Stock owned by such seller,
except that the Company shall not for any such purpose be required to qualify
generally to do business as a foreign corporation in any jurisdiction where, but
for the requirements of this paragraph (g), it would not be obligated to be so

thereto is required to be delivered under the Securities Act within the
appropriate period of the Company's becoming aware that the prospectus included
in such registration statement, as then in effect, includes an untrue statement
of a material fact or omits to state a material fact required to be stated

                  3.10               Indemnification.
                                     ---------------

                  (a) INDEMNIFICATION BY THE COMPANY. In the event of any
registration of any securities of the Company under the Securities Act pursuant
to Section 3.7 or 3.8, the Company hereby indemnifies and agrees to hold
harmless, to the extent permitted by law, each party hereto who is a holder
("HOLDER") of securities ("REGISTRABLE SECURITIES") covered by such registration
statement, each Affiliate of such Holder and their respective directors and
officers or general and limited partners (and the directors, officers,
affiliates and controlling Persons thereof), each other Person who participates
as an underwriter in the offering or sale of such securities and each other
Person, if any, who controls such Holder or any such underwriter within the
meaning of the Securities Act (collectively, the "INDEMNIFIED PARTIES"), against
any and all losses, claims, damages or liabilities, joint or several, and
expenses to which such 

<PAGE>   19
                                                                              17




Indemnified Party may become subject under the Securities Act, common law or
otherwise, insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof, whether or not such Indemnified Party is a party
thereto) arise out of or are based upon (i) any untrue statement or alleged
untrue statement of any material fact contained in any registration statement
under which such securities were registered under the Securities Act, any
preliminary, final or summary prospectus contained therein, or any amendment or
supplement thereto, or (ii) any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing, and the
Company will reimburse such Indemnified Party for any legal or other expenses
reasonably incurred by it in connection with investigating or defending any such
loss, claim, liability, action or proceeding; PROVIDED, that the Company shall
not be liable to any Indemnified Party in any such case to the extent that any
such loss, claim, damage, liability (or action or proceeding in respect thereof)
or expense arises out of or is based upon any untrue statement or alleged untrue
statement or omission or alleged omission made in such registration statement,
in any such preliminary, final or summary prospectus, or any amendment or
supplement thereto in reliance upon and in conformity with written information
with respect to such Indemnified Party furnished to the Company by such
Indemnified Party for use in the preparation thereof; and PROVIDED, FURTHER,
that the Company will not be liable to any Person who participates as an
underwriter in the offering or sale of Registrable Securities or any other
Person, if any, who controls such underwriter within the meaning of the
Securities Act, under the indemnity agreement in this Section 3.10(a) with
respect to any preliminary prospectus or the final prospectus or the final
prospectus as amended or supplemented, as the case may be, to the extent that
any such loss, claim, damage or liability of such underwriter or controlling
Person results from the fact that such underwriter sold Registrable Securities
to a person to whom there was not sent or given, at or prior to the written
confirmation of such sale, a copy of the final prospectus or of the final
prospectus as then amended or supplemented, whichever is most recent, if the
Company has previously furnished copies thereof to such underwriter. Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of such Holder or any Indemnified Party and shall survive
the transfer of such securities by such Holder.

                  (b) INDEMNIFICATION BY THE HOLDERS AND UNDERWRITERS. The
Company may require, as a condition to including any Registrable Securities in
any registration statement filed in accordance with Section 3 herein, that the
Company shall have received an undertaking reasonably satisfactory to it from
the Holder of such Registrable Securities or any prospective underwriter to
indemnify and hold harmless (in the same manner and to the same extent as set
forth in Section 3.10(a)) the Company, all other Holders or any prospective
underwriter, as the case may be, and any of their respective Affiliates,
directors, officers and controlling Persons, with respect to any statement

<PAGE>   20
                                                                              18




or alleged statement in or omission or alleged omission from such registration
statement, any preliminary, final or summary prospectus contained therein, or
any amendment or supplement, if such statement or alleged statement or omission
or alleged omission was made in reliance upon and in conformity with written
information with respect to such Holder or underwriter furnished to the Company
by such Holder or underwriter expressly for use in the preparation of such
registration statement, preliminary, final or summary prospectus or amendment or
supplement, or a document incorporated by reference into any of the foregoing.
Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of the Company or any of the Holders, or any
of their respective affiliates, directors, officers or controlling Persons and
shall survive the transfer of such securities by such Holder.

                  (c) NOTICES OF CLAIMS, ETC. Promptly after receipt by an
indemnified party hereunder of written notice of the commencement of any action
or proceeding with respect to which a claim for indemnification may be made
pursuant to this Section 3.10, such indemnified party will, if a claim in
respect thereof is to be made against an indemnifying party, give written notice
to the latter of the commencement of such action; PROVIDED, that the failure of
the indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations under Sections 3.10(a) or 3.10(b), except
to the extent that the indemnifying party is actually prejudiced by such failure
to give notice. In case any such action is brought against an indemnified party,
unless in such indemnified party's reasonable judgment a conflict of interest
between such indemnified and indemnifying parties may exist in respect of such
claim, the indemnifying party will be entitled to participate in and to assume
the defense thereof, jointly with any other indemnifying party similarly
notified to the extent that it may wish, with counsel reasonably satisfactory to
such indemnified party, and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party will not be liable to such indemnified party for any legal or
other expenses subsequently incurred by the latter in connection with the
defense thereof other than reasonable costs of investigation. If, in such
indemnified party's reasonable judgment, having common counsel would result in a
conflict of interest between the interests of such indemnified and indemnifying
parties, then such indemnified party may employ separate counsel reasonably
acceptable to the indemnifying party to represent or defend such indemnified
party in such action, it being understood, however, that the indemnifying party
shall not be liable for the reasonable fees and expenses of more than one
separate firm of attorneys at any time for all such indemnified parties (and not
more than one separate firm of local counsel at any time for all such
indemnified parties) in such action. No indemnifying party will consent to entry
of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect of such claim or

<PAGE>   21
                                                                              19




litigation.

                  (d) OTHER INDEMNIFICATION. Indemnification similar to that
specified in this Section 3.10 (with appropriate modifications) shall be given
by the Company and each Holder of Registrable Securities with respect to any
required registration or other qualification of securities under any federal or
state law or regulation or governmental authority other than the Securities Act.

                  (e) CONTRIBUTION. If recovery is not available under the
foregoing indemnification provisions of this Section 3.10 for any reason other
than as expressly specified therein, the parties entitled to indemnification by
the terms thereof shall be entitled to contribution to liabilities and expenses
except to the extent that contribution is not permitted under Section 11(f) of
the Securities Act. In determining the amount of contribution to which the
respective parties are entitled, there shall be considered the relative benefits
received by each party from the offering of the Registrable Securities (taking
into account the portion of the proceeds realized by each), the parties'
relative knowledge and access to information concerning the matter with respect
to which the claim was asserted, the opportunity to correct and prevent any
misstatement or omission and any other equitable considerations appropriate
under the circumstances.

                  (f) NON-EXCLUSIVITY. The obligations of the parties under this
Section 3.10 shall be in addition to any liability which any party may otherwise
have to any other party.


                  SECTION 4.  OTHER

                  4.1 ADDITIONAL SECURITIES SUBJECT TO AGREEMENT. Each
Stockholder agrees that any other shares of Common Stock which it shall
hereafter acquire by means of a stock split, stock dividend, distribution,
exercise of options or warrants or otherwise (other than pursuant to a Public
Offering) shall be subject to the provisions of this Agreement to the same
extent as if held on the date hereof.

                  4.2 TERMINATION. This Agreement shall terminate, and thereby
become null and void, in full on the earliest date on which the Blackstone
Investors and their Affiliates do not collectively own, directly or through the
Partnerships as Class B Assets, in the aggregate at least 15% of the Common
Stock then outstanding on a fully diluted basis; PROVIDED, that the provisions
of Sections 3.7, 3.8, 3.9 and Sections 4.1, 4.2, 4.3, 4.5, 4.6, 4.7, 4.8, 4.9,
4.10, 4.11 and 4.13 shall survive until such time as none of the Blackstone
Investors and their Affiliates own, directly or through the Partnerships as
Class B Assets, any shares of Common Stock, and the provisions of Section 3.10
shall not terminate. The provisions of Section 4.12 shall terminate when either
the Blackstone Investors, (directly or indirectly through the Partnerships as
Class B Assets) on the one hand, or the Partnerships on the other hand, own less
than 10% of 

<PAGE>   22
                                                                              20




the Common Stock on a fully diluted basis.

                  4.3 INJUNCTIVE RELIEF. The Stockholders acknowledge and agree
that a violation of any of the terms of this Agreement will cause the
Stockholders irreparable injury for which adequate remedy at law is not
available. Accordingly, it is agreed that each Stockholder shall be entitled to
an injunction, restraining order or other equitable relief to prevent breaches
of the provisions of this Agreement and to enforce specifically the terms and
provisions hereof in any court of competent jurisdiction, in addition to any
other remedy to which they may be entitled at law or equity.

                  4.4 OTHER STOCKHOLDERS' AGREEMENTS. None of the Stockholders
shall enter into any stockholder agreement or other arrangement of any kind with
any Person with respect to shares of Common Stock or securities convertible into
or exercisable or exchangeable for Common Stock (other than the Common Stock
Registration Rights Agreement, dated as of the date hereof, with Chase
Securities Inc.), and none of the Stockholders has previously entered into such
an agreement that remains in full force and effect as of the date hereof, which
is inconsistent with the provisions of this Agreement or which may impair its
ability to comply with this Agreement.

                  4.5 AMENDMENTS. This Agreement may be amended only by a
written instrument signed by each of the Blackstone Investors, so long as such
Blackstone Investor (or any Affiliate of such Blackstone Investor) beneficially
owns, directly or through the Partnerships, Common Stock; provided that, any
amendment which adversely affects the Company, the Partnerships, the Veritas
Investors, the Trustee or a Management Stockholder or imposes an additional
material obligation on the Company, the Partnerships, the Veritas Investors, the
Trustee or a Management Stockholder, must be approved in writing by such party.

                  4.6 SUCCESSORS, ASSIGNS AND TRANSFEREES. The provisions of
this Agreement shall be binding upon and shall inure to the benefit of the
parties hereto and their respective successors and transferees permitted
hereunder (except for transferees that are transferred Common Stock pursuant to
a Public Offering or a transaction pursuant to Rule 144 under the Securities Act
or pursuant to Section 3.5), each of which shall agree in a writing reasonably
satisfactory in form and substance to the Company to become a party hereto and
be bound to the same extent hereby as the transferor that has transferred the
Common Stock to such transferees; PROVIDED, that if a Stockholder transfers a
portion of its or his Common Stock to a transferee which is entitled to rights
of the transferor hereunder, then such transferee(s) of such transferor shall
exercise such rights as a single group with that transferor and its Affiliates.

                  4.7 NOTICES. Any notices or other communications required or
permitted hereunder shall be sufficiently given if delivered personally or sent
by telecopier, Federal Express or other overnight courier, addressed as follows

                  4.8 INTEGRATION. This Agreement, the agreements entered into

                  4.9 SEVERABILITY. If one or more of the provisions,
paragraphs, words, clauses, phrases or sentences contained herein, or the

Each of the parties


<PAGE>   25
                                                                              23




by its execution hereof hereby (i) irrevocably submits to the jurisdiction of
the federal and state courts located in the Southern District of New York for
the purpose of any suit, action or other proceeding arising out of or based upon
this Agreement or any other agreement contemplated hereby or relating to the
subject matter hereof or thereof and (ii) waives to the extent not prohibited by
applicable law, and agrees not to assert by way of motion, as a defense or
otherwise, that its property is exempt or immune from attachment or execution,
that any such proceeding brought in one of the above-named courts is improper,
or that any right or remedy relating to this Agreement or any other agreement
contemplated hereby, or the subject matter hereof or thereof, may not be
enforced in or by such court. Each of the parties hereby consents to service of
process in any such proceeding in any manner permitted by the laws of the State
of New York, and agrees that service of process by registered or certified mail,
return receipt requested, at its address specified pursuant to Section 3.7
hereof is reasonably calculated to give actual notice.

                  4.12 AFFILIATE TRANSACTIONS. (a) The Company shall not agree
to, engage in or otherwise complete any Affiliate Transaction other than a
transaction determined in advance of such transaction by the Board of Directors
of the Company as being upon terms no less favorable to the Company than terms
obtainable from a third party on an arms-length basis. For purposes of this
Section 4.12, "Affiliate Transaction" means any transaction or series of related
transactions including, but not limited to, the purchase, sale, lease or
exchange of any property or the rendering of any service pursuant to any
management or consulting arrangement or otherwise, but excluding (v) the payment
of annual monitoring fees to any Blackstone Investor or the Partnerships or any
of their respective Affiliates (so long as the fees payable to the Blackstone
Investors and their Affiliates, on the one hand, and to the Partnerships and
their Affiliates, on the other hand, are equal), (w) the reimbursement of
out-of-pocket expenses of directors for services rendered in such capacity, (x)
the payment of customary directors' fees, (y) the payment of customary
investment banking fees to any Blackstone Investor or the Partnerships or an
Affiliate of a Blackstone Investor or the Partnerships in consideration of
services rendered and (z) transactions expressly contemplated by the
Subscription Agreement and the exhibits thereto) between the Company or any of
its subsidiaries, on the one hand, and any Affiliate of the Company (other than
the Company or any of its subsidiaries), on the other hand, or by the Company or
any of its subsidiaries for the benefit of any Affiliate of the Company (other
than the Company or any of its subsidiaries).

                  (b) Provided (i) the Blackstone Investors collectively
continue to own (directly or through the Partnerships as Class B Assets) at
least 40% of the outstanding Common Stock or (ii) (A) the Blackstone Investors
otherwise have the right to designate the Company's nomination of a number of
directors constituting more than 50% of the voting power of the Board and (B)
the number of shares of Common Stock held by holders of Common Stock
contractually obligated to vote for such designees assures


<PAGE>   26
                                                                              24



election of such designees without regard to any other shares voting for the
election of directors, then if the Company or any of its subsidiaries proposes
to enter into a "Blackstone Interested Transaction" (as defined below), the
Company shall not consummate such transaction unless it shall have been approved
by a committee of independent directors of the Company's Board of Directors
(i.e., directors not designated by the Blackstone Investors or otherwise
personally interested in the transaction (other than as stockholders pari passu
with other stockholders)).

                  A Blackstone Interested Transaction is any transaction whereby
ownership of the Company or a material part of its operating assets would
succeed to an entity controlled by the Blackstone Investors or their Affiliates,
and in such transaction (i) the post-transaction ownership stake in such entity
held by the Blackstone Investors would increase disproportionately to the
post-transaction ownership stake in such entity that would be held by the
Partnerships (through their Class A Assets), as compared to its stake
immediately prior to consummation of such Transaction or (ii) any Blackstone
Investor or any Affiliate thereof would receive any consideration that is
disproportionate as compared to the Partnerships (other than customary
investment banking fees that may be paid to the Blackstone Investors or their
Affiliates) (other than in the case of either clause (i) or (ii) any such
disproportional impact attributable solely to the preference accorded to Class B
Common Stock).

                  4.13 MISCELLANEOUS. (a) The parties hereto shall sign such
further documents, cause such meetings to be held, resolutions passed and bylaws
enacted, exercise their votes and do and perform and cause to be done such
further acts and things as maybe necessary or desirable in order to give full
effect to this Agreement and every part thereof.

                  (b) Each of the Trustee and the Management Stockholders shall
become an additional signatory hereto as soon as practicable by signing a
counterpart of this Agreement and delivering same to the Company and the other
parties hereto and, until such time, shall have no rights or obligations
hereunder.
