and cause to be continued in office, the following individuals:

Holders (to the extent the Management Manager or Management Managers are
designated by the Majority Executives) notify the other parties to this
Agreement of his or their desire to remove, with or without cause, any
Management Manager, all such parties so notified will vote, or cause to be
voted, all voting securities of the Company and the Subsidiaries of the Company
over which they have the power to vote or direct the voting, and shall take all
such other actions promptly as shall be necessary or desirable to cause the
removal of such manager.

 

(e)                                  If at any time
a Management Manager (other than Dr. Dosoretz) ceases to be employed by
the Company or any of its Subsidiaries, such Management Manager shall be deemed
to have resigned from the Company and, unless otherwise reasonably determined
by Vestar V and Dr. Dosoretz or the Majority Executives (as applicable),
such Management Manager will be promptly removed from the Board.

 

(f)                                    If at any time
any Vestar Manager or any Independent Manager ceases to serve on the Board and

(whether due to resignation, removal or otherwise), Vestar V shall be entitled
to designate a successor manager (provided, that with respect to any successor
to an Independent Manager, after consultation with Dr. Dosoretz) to fill

paragraph (a) above. Each Person that is a party hereto agrees to vote, or
cause to be voted, all voting securities of the Company and the aforementioned
Subsidiaries over which such Person has the power to vote or direct the voting,
and shall take all such other actions as shall be necessary or desirable to
cause the designated successor to be elected to fill such vacancy.

 

(g)                                 If at any time
any Management Manager (other than Dr. Dosoretz) ceases to serve on Board
and the board of managers (or similar governing body) of the Company’s

 

4

 

Subsidiaries (whether due to resignation, removal or
otherwise), the Chief Executive Officer of RTS or the Majority Executives, as
applicable, shall be entitled to designate a successor manager to fill the
vacancy created thereby on the terms and subject to the conditions of paragraph
(a) above. Each Person that is a party hereto agrees to vote, or cause to
be voted, all voting securities of the Company and the aforementioned
Subsidiaries over which such Person has the power to vote or direct the voting,
and shall take all such other actions as shall be necessary or desirable to
cause the designated successor to be elected to fill such vacancy.

 

(h)                                 Dr. Dosoretz
shall resign from the Board effective immediately if (x) his employment is
terminated by the Company for Cause (as defined in his Employment Agreement
with the Company), (y) his employment is terminated by the Company or he
resigns and at the time of such termination or resignation, the Put Option is
exercisable pursuant to the Dosoretz Rollover Subscription Agreement, whether
or not Dr. Dosoretz elects to exercise such option, or (z) the
Company exercises its repurchase option pursuant to Section 5.2 of the
Dosoretz Rollover Subscription Agreement with respect to a portion of the Units
held by Dr. Dosoretz that is at least equal to the number of Units that

pursuant to the Put Option at such time; provided, that, notwithstanding
anything to the contrary in this Agreement, Dr. Dosoretz shall not be
designated or elected as a Management Manager at any time after his resignation
from the Board pursuant to this Section 2.1(h).

 

(i)                                     No manager may
be removed except by vote of the Persons entitled to designate such manager;
provided that Dr. Dosoretz may only cease to serve as a manager on the
Board pursuant to Section 2.1(h) above.

 

2.2                                 Proxy.

 

(a)                                  In order to
effectuate the provisions of Section 4.1 hereof, each holder of Employee
Securities hereby grants to each of (i) Vestar V, and (ii) Dr. Dosoretz,
or if Dr. Dosoretz shall cease to be the Chief Executive Officer of RTS,
to the then-current Chief Executive Officer of RTS, or if the Chief Executive
Officer of RTS shall be unable to exercise this proxy due to illness or absence
or if the position of Chief Executive Officer of RTS shall be vacant, to the
Chief Financial Officer of RTS, each such person to have the power to act
independently, a proxy to vote at any annual or special meeting of Securityholders,
or to take any action by written consent in lieu of such meeting with respect
to, or to otherwise take action in respect of, all of the Securities owned or
held of record by such holder in connection with the matters set forth in
Section 4.1 hereof in accordance with the provisions of Section 4.1
hereof. Each of the proxies granted hereby is irrevocable and is coupled with
an interest. To effectuate the provisions of this Article II, the
Secretary of each of the Company and each of the aforementioned Subsidiaries of
the Company, or if there be no Secretary such other officer or employee of the
Company or such Subsidiaries as the board of directors (or similar governing
body) of the Company or such Subsidiaries may appoint to fulfill the duties of
the Secretary, shall not record any vote or consent or other action contrary to
the terms of this Article II.

 

(b)                                 The provisions
of this Article II shall terminate immediately prior to the consummation
of an initial Public Offering; provided that the provisions of this Article II
shall remain in effect following an initial Public Offering with respect to
Securityholders who are

 

5

 

otherwise (i.e., not due to the formation of a group
pursuant to this Agreement) subject to the reporting requirements of Section 16(a) of
the Exchange Act, for so long as they remain subject thereto and Vestar holds
at least 20% of the fully-diluted voting equity securities of the Company, in
order to (i) vote in favor of the election of any designees of Vestar V to
the Board or the board of directors (or similar governing bodies) of the
Company’s Subsidiaries and any successors thereto and (ii) support any
transaction that if consummated would constitute a Sale of the Company that is
supported by Vestar V.

 

2.3 Matters Requiring
Supermajority Vote.

 

(a)                                  Notwithstanding
anything to the contrary contained in this Agreement or the LLC Agreement,
without the prior written consent of the Majority Executives, no action shall
be taken or resolution be passed by the Company, any of its Subsidiaries, the
Board or the board of directors (or similar governing body) of any Subsidiary
with respect to the following matters:

 

(i)                                     a material
change in the nature of the Company’s business; provided, however,
the following actions and events shall not be deemed a material change in the
nature of the Company’s business: (i) changes in the size, geographic
scope or markets in which the business is conducted or the relative mix of the
Company’s business lines, whether as the result of any acquisition,
divestiture, combination, organic growth or otherwise, (ii) discontinuation
of ancillary businesses not necessary to the provision of radiation therapy
services and changes in the method of conducting such ancillary businesses,
(iii) discontinuation and/or divestiture of service line or industry
segment outside of the Core Business, and (iv) changes in response to
local, state or federal government activity, whether in the form of legislative
or regulatory action or published guidance;

 

(ii)                                  any transaction
with Vestar or its Affiliates, other than (i) any transactions involving
an aggregate amount not to exceed $300,000 in any particular fiscal year
(excluding any fee payable to Vestar Capital Partners pursuant to the
Management Agreement), (ii) any issuance of New Units to Vestar and/or its
Affiliates so long as the Employees are granted Participation Rights with
respect to such issuance in accordance with Article VIII hereof, (iii) any
transaction between the Company and Vestar in its capacity as a holder of
Securities of the Company, (iv) any transaction that does not
disproportionately affect Vestar as compared to other holders of the same class
of Units or (v) any transaction contemplated by the Transaction
Documents);

 

(iii)                               alter, amend or
change any of the rights, preferences or characteristics of any Vestar
Preferred Units having the effect of rendering the Vestar Preferred Units
superior to the Employee Preferred Units;

 

(iv)                              make any
distributions on the Vestar Preferred Units that are disproportionate to the
distributions or dividends paid on the Employee Preferred Units; or

 

(v)                                 effect any
redemption or repurchase of the Vestar Preferred Units that is disproportionate
to the redemption or repurchase of the Employee Preferred Units.

(b)                                 Sections

to occur of (x) the consummation of a Public Offering and (y) the
time upon which the aggregate amount of Class A Units held by the

TRANSFERS OF SECURITIES

 

3.1                                 Restrictions on
Transfer of Employee Securities, TCW Securities and NYLIM Securities. Prior to the
earlier of (i) a Sale of the Company and (ii) the consummation of the
initial Public Offering, no holder of Employee Securities, TCW Securities or
NYLIM Securities may Transfer any Employee Securities, TCW Securities or NYLIM
Securities, as the case may be, without the prior written consent of Vestar V
(which may be withheld in its sole discretion), except in an Exempt Employee
Transfer, an Exempt TCW Transfer or an NYLIM Exempt Transfer, as applicable.

 

3.2                                 Right of First
Refusal.

 

(a)                                  If any holder
of Employee Securities, TCW Securities or NYLIM Securities (for purposes of
this Section 3.2(a), a “Selling Security Holder”) proposes to sell
any or all of his Employee Securities, TCW Securities or NYLIM Securities, as
the case may be (other than an Exempt Employee Transfer, an Exempt TCW Transfer
or an Exempt NYLIM Transfer) to a third party (a “Proposed Sale”) prior
to (A) a Public Offering resulting in a public market for the Securities
and (B) a Sale of the Company, and Vestar V has consented to such Proposed
Sale (which consent may be withheld in its sole discretion), such Selling
Security Holder shall first notify the Company in writing, which notice shall
(i) state such Selling Security Holder’s intention to sell Employee
Securities, TCW Securities or NYLIM Securities, as the case may be, to one or
more persons, the amount of Employee Securities, TCW Securities or NYLIM
Securities to be sold, the purchase price therefor, the identity of each
prospective Transferee, if known, and the other material terms of the Proposed
Sale and (ii) contain an irrevocable offer to sell such Employee Securities,
TCW Securities or NYLIM Securities to the Company (in the manner set forth
below) at a purchase price equal to the price contained in, and on the same
terms and conditions of, the Proposed Sale (such notice, the “Proposed Sale
Notice”).

 

(b)                                 At any time
within thirty (30) days after the date of the receipt by the Company of the
Proposed Sale Notice, the Company shall have the right and option to purchase,
or to arrange for a third party to purchase, all of the Employee Securities,
all of the TCW Securities or all of the NYLIM Securities (as the case may be)
covered by the Proposed Sale

Notice at the same price and on the same terms and
conditions of the Proposed Sale (or, if the Proposed Sale includes any
consideration other than cash, then, at the sole option of the Company, at the
equivalent all cash price, determined in good faith by the Board, as
applicable), by delivering a certified bank check or checks in the appropriate
amount (or by wire transfer of immediately available funds, if the Selling
Security Holder provides to the Company wire transfer instructions) (and any
such non-cash consideration to be paid) to the Selling Security Holder at the
principal office of the Company against delivery of certificates or other
instruments representing the Employee Securities, TCW Securities or NYLIM
Securities so purchased, appropriately endorsed by the Selling Security Holder.
If at the end of the 30-day period, the Company has not elected to exercise its
right to purchase all of the Employee Securities, all of TCW Securities or all
of the NYLIM Securities (as the case may be) covered by the Proposed Sale
Notice as described above or the Company has not tendered the purchase price
for such securities in the manner set forth above, Vestar shall have the right
and option for fifteen (15) days after the end of the aforementioned 30-day
period to purchase all of the Employee Securities, all of the TCW Securities or
all of the NYLIM Securities (as the case may be) covered by the Proposed Sale
Notice at the same price and on the same terms and conditions of the Proposed
Sale (or, if the Proposed Sale includes any consideration other than cash,
then, at the sole option of Vestar, at the equivalent all cash price,
reasonably determined in good faith by mutual agreement of the Selling Security
Holder and Vestar (provided that in the event the Selling Security Holder and
Vestar are unable to mutually agree on such cash price, then such determination
shall be made in accordance with Section 9.11 of this Agreement), by
delivering a certified bank check or checks in the appropriate amount (or by
wire transfer of immediately available funds, if the Selling Security Holder
provides to Vestar wire transfer instructions) (and any such non-cash
consideration to be paid) to the Selling Security Holder at the principal
office of the Company against delivery of certificates or other instruments
representing the Employee Securities, TCW Securities or NYLIM Securities so
purchased, appropriately endorsed by the Selling Security Holder. If at the end
of the 15-day period, neither the Company nor Vestar has tendered the purchase
price for such securities in the manner set forth above, the Selling Security
Holder may, during the succeeding 30-day period, sell not less than all of the
Employee Securities, all of the TCW Securities or all of the NYLIM Securities
(as the case may be) covered by the Proposed Sale to a third party on terms no
less favorable to Selling Security Holder than those contained in the Proposed
Sale Notice. Promptly after such sale, the Selling Security Holder shall notify
the Company of the consummation thereof and shall furnish such evidence of the
completion and time of completion of such sale and of the terms thereof as may
reasonably be requested by the Company. If, at the end of sixth (60) days
following the expiration of the 30-day period during which the Company is
entitled hereunder to purchase the Employee Securities, TCW Securities or NYLIM
Securities, the Selling Security Holder has not completed the sale of such
securities as aforesaid, all of the restrictions on sale, transfer or assignment
contained in this Agreement shall again be in effect with respect to such
Employee Securities, TCW Securities or NYLIM Securities. Any action by Vestar
contemplated by this Section 3.2(b) shall be deemed to have been
taken by Vestar if such action is taken by the Vestar Majority Holders.

 

3.3                                 Restrictions on
Transfers of Vestar Securities.

 

(a)                                  Tag-Along
Rights. Subject to the next paragraph, prior to making any Transfer of Vestar
Securities (other than a Transfer described in Section 3.3(b)) any holder
of

 

8

 

Vestar Securities proposing to make such a Transfer
(for purposes of this Section 3.3, a “Selling Vestar Holder”) shall
give at least fifteen (15) days’ prior written notice to each holder of
Employee Securities, TCW Securities and NYLIM Securities (for purposes of this
Section 3.3, each an “Other Holder”) and the Company, which notice
(for purposes of this Section 3.3, the “Sale Notice”) shall
identify the type and amount of Vestar Securities to be sold (for purposes of
this Section 3.3, the “Offered Securities”), describe the terms and
conditions of such proposed Transfer, and identify each prospective Transferee.
Any of the Other Holders may, within fifteen (15) days of the receipt of the
Sale Notice, give written notice (each, a “Tag-Along Notice”) to the
Selling Vestar Holder that such Other Holder wishes to participate in such
proposed Transfer upon the terms and conditions set forth in the Sale Notice,
which Tag-Along Notice shall specify the Employee Securities, TCW Securities or
NYLIM Securities, as the case may be, such Other Holder desires to include in
such proposed Transfer; provided, however, that (1) each
Other Holder shall be required, as a condition to being permitted to sell
Employee Securities, TCW Securities and NYLIM Securities pursuant to this
Section 3.3(a) in connection with a Transfer of Offered Securities,
to elect to sell Employee Securities, TCW Securities and NYLIM Securities of
the same type and class (for purpose of this Section 3.3, the Common Units
shall be treated as a single class, provided that the proceeds to be received
by the holders thereof shall take into account any differences in distribution
rights with respect to the Class A Units, Class B Units, Class C Units and other
Units constituting Common Units pursuant to Section 4.1 of the LLC
Agreement) and in the same relative proportions (which proportions shall be
determined on a unit for unit or, as the case may be, share for share basis and
on the basis of aggregate liquidation value with respect to Preferred Units or
Preferred Stock) as the Securities which comprise the Offered Securities, (2) no
Employee Security that is subject to vesting shall be entitled to be sold
pursuant to this Section 3.3(a) unless such Employee Security has
fully vested; and (3) to exercise its tag-along rights hereunder, each
Other Holder must agree to make to the Transferee the same representations,
warranties, covenants, indemnities and agreements as the Selling Vestar Holder
agrees to make in connection with the Transfer of the Offered Securities
(except that in the case of representations and warranties pertaining
specifically to, or covenants made specifically by, the Selling Vestar Holder,
the Other Holders shall make comparable representations and warranties
pertaining specifically to (and, as applicable, covenants by) themselves), and
must agree to bear his or its ratable share (which may be joint and several but
contribution shall be based on the proceeds received in respect of Securities
that are Transferred by each holder) of all liabilities to the Transferees
arising out of representations, warranties and covenants (other than those
representations, warranties and covenants that pertain specifically to a given
Securityholder, who shall bear all of the liability related thereto),
indemnities or other agreements made in connection with the Transfer. Each
Securityholder will bear (x) its or his own costs of any sale of
Securities pursuant to this Section 3.3(a) and (y) its or his
pro-rata share (based upon the relative amount of Securities sold) of the costs
of any sale of Securities pursuant to this Section 3.3(a) (excluding
all amounts paid to any Securityholder or his or its Affiliates as a
transaction fee, broker’s fee, finder’s fee, advisory fee, success fee, or
other similar fee or charge related to the consummation of such sale) to the
extent such costs are incurred for the benefit of all Securityholders and are
not otherwise paid by the Transferee.

 

If none of the Other Holders
gives the Selling Vestar Holder a timely Tag-Along Notice with respect to the
Transfer proposed in the Sale Notice, then (notwithstanding the first sentence
of this Section 3.3(a)) the Selling Vestar Holder may Transfer such
Offered Securities on the terms and conditions set forth, and to or among any
of the Transferees identified (or

 

9

 

Affiliates of Transferees identified), in the Sale
Notice at any time within one hundred twenty (120) days after expiration of the
fifteen (15) day period for giving Tag-Along Notices with respect to such
Transfer. Any such Offered Securities not Transferred by the Selling Vestar
Holder during such 120-day period will again be subject to the provisions of
this Section 3.3(a) upon subsequent Transfer. If one or more Other
Holders give the Selling Vestar Holder a timely Tag-Along Notice, then the
Selling Vestar Holder shall use all reasonable efforts to obtain the agreement
of the prospective Transferee(s) to the participation of the Other Holders
in any contemplated Transfer, on the same terms and conditions as are
applicable to the Offered Securities, and no Selling Vestar Holder shall
transfer any of its units or shares, as the case may be, to any prospective
Transferee if such prospective Transferee(s) declines to allow the
participation of the Other Holders, unless Vestar agrees to purchase the Units
that such Other Holders are entitled to sell and have elected to sell in
connection with such Transfer. If the prospective Transferee(s) is
unwilling or unable to acquire all of the Offered Securities and all of the
Employee Securities, TCW Securities and NYLIM Securities specified in a timely
Tag-Along Notice upon such terms, then the Selling Vestar Holder may elect
either to cancel such proposed Transfer or to allocate the maximum number of
each class of Securities that the prospective Transferees are willing to
purchase (the “Allocable Shares”) among the Selling Vestar Holder and
the Other Holders giving timely Tag-Along Notices as follows (it being
understood that the prospective Transferees shall be required to purchase
Securities of the same class on the same terms and conditions taking into
account the provisions of clause (1) of the first paragraph of this
Section 3.3(a), and to consummate such Transfer on those terms and
conditions):

 

(i)                                     each
participating Securityholder (including the Selling Vestar Holder) shall be
entitled to sell a number of Units or shares of each class of Securities
(taking into account the provisions of clause (1) of the first paragraph
of this Section 3.3(a)) (not to exceed, for any Other Holder, the number
of Units or shares of such class of Securities identified in such Other
Holder’s Tag-Along Notice) equal to the product of (A) the number of Allocable
Shares of such class of Securities and (B) a fraction, the numerator of
which is such Securityholder’s Ownership Percentage of such class of Securities
and the denominator of which is the aggregate Ownership Percentage for all
participating Securityholders of such class of Securities; provided, however,
that if a Securityholder was unable to sell Securities in one or more prior
Transfers effected pursuant to this Section 3.3(a) because of clause
(2) of the first paragraph of this Section 3.3(a) and, as a
result, the aggregate percentage of Securities sold by such Securityholder in
Transfers effected pursuant to this Section 3.3(a) is less than the
aggregate percentage of Securities sold by Vestar in such Transfers, then
additional Allocable Shares shall be allocated to such Securityholder (not to
exceed the number of Securities identified in such Securityholder’s Tag-Along
Notice) in priority over other Securityholders until, after giving effect to
the Transfer proposed to be effected, the aggregate percentage of Securities
sold by Vestar and such Securityholder are equal;

 

(ii)                                  if after
allocating the Allocable Shares of any class of Securities to such
Securityholders in accordance with clause (i) above, there are any
Allocable Shares of such class that remain unallocated, then they shall be
allocated (in one or more successive allocations on the basis of the allocation
method specified in clause (i) above, among the Selling Vestar Holder and
each such Other Holder that has elected in its Tag-

 

10

 

Along Notice to sell a
greater number of shares of such class of Securities than previously has been
allocated to it pursuant to clause (i) and this clause (ii) (all of
whom (but no others) shall, for purposes of clause (i) above, be deemed to
be the participating Securityholders) until all such Allocable Shares have been
allocated in accordance with this clause (ii).

 

(b)                                 Excluded
Transfers. The rights and restrictions contained in Section 3.3(a) shall
not apply with respect to any of the following Transfers of Securities:

 

(i)                                     any Transfer of
Vestar Securities in a Public Sale;

 

(ii)                                  any Transfer of
Vestar Securities to and among (A) the members or partners of Vestar and
the members, partners, securityholders and employees of such partners or (B) wholly
owned subsidiaries of Vestar or any Person controlled by or under the common
control with Vestar and its affiliated funds (but excluding any portfolio
company of Vestar or its affiliated funds) or (C) any Person controlled by
any Person described above (subject to compliance with Sections 3.4 and 3.5
hereof);

 

(iii)                               any Transfer of
Vestar Securities in accordance with Section 4.1;

 

(iv)                              any Transfer of
Vestar Securities incidental to the exercise, conversion or exchange of such
securities in accordance with their terms or any reclassification or
combination of shares (including any reverse stock split);

 

(v)                                 any Transfer of
Vestar Securities to employees or directors of, or consultants to, any of the
Company and its Subsidiaries;

 

(vi)                              any Transfer
constituting an Exempt Individual Transfer;

 

(vii)                           any Transfer of
Vestar Securities within 30 days after the date of the Original Agreement to
any Person whom Vestar V determines will be an equity co-investor with Vestar
in the Company (any such equity co-investor, a “Selldown Investor” and
all such Securities being referred to as “Selldown Securities”),
provided that Vestar V shall continue to hold at least a majority of Class A
Units of the Company after giving effect to such Transfer unless Dr. Dosoretz
agrees otherwise; and

 

(viii)                        any direct or
indirect Transfer of Vestar Securities by Vestar/RTI to certain lenders (and/or
their Affiliates) who are providing mezzanine financing to RTS and its
Subsidiaries and/or Affiliates in connection with any sale or transfer of
Vestar V’s investment in Vestar/RTS, in whole or in part, to such lenders
(and/or their Affiliates).

 

(c)                                  Excluded
Securities. No Securities that have been transferred by the Selling
Vestar Holder or an Other Holder in a Transfer pursuant to the provisions of
Section 3.3(a) (“Excluded Securities”) shall be subject again
to the restrictions set forth in Section 3.3(a), nor shall any
Securityholder holding Excluded Securities be entitled to exercise any rights
as an Other Holder under Section 3.3(a) with respect to such Excluded
Securities, and no Excluded Securities held by a Selling Vestar Holder or any
Other Holder shall be counted in

 

11

 

determining the respective participation rights of
such Holders in a Transfer subject to Section 3.3(a).

 

(d)                                 The provisions
of this Section 3.3 shall terminate immediately prior to the consummation
of the initial Public Offering.

 

3.4                                 Securities Act
Compliance. No Securities may be transferred by a Securityholder
(other than pursuant to an effective registration statement under the
Securities Act) unless such Securityholder first delivers to the Company an
opinion of counsel, which opinion and counsel shall be reasonably satisfactory
to the Company, to the effect that such Transfer is not required to be
registered under the Securities Act.

 

3.5                                 Certain
Transferees Bound by Agreement. Subject to compliance with
the other provisions of this Article III and the LLC Agreement, any Securityholder
may Transfer any Securities held by such Securityholder in accordance with
applicable law; provided, however, that if the Transfer is not
made pursuant to a Public Sale or a transaction the consummation of which will
cause the termination of this Agreement pursuant to Article VI, then the
Transferor of such Security shall first deliver to the Company a written
agreement of the proposed Transferee (excluding a Transferee that is a Limited
Partner) to become a Securityholder and to be bound by the terms of this
Agreement (unless such proposed Transferee is already a Securityholder). All
Employee Securities, TCW Securities and NYLIM Securities will continue to be
Employee Securities, TCW Securities and NYLIM Securities, respectively, in the
hands of any Transferee (other than the Company, Vestar, any Transferee in a
Public Sale or any Transferee in a Transfer pursuant to clause (e) of an
Exempt TCW Transfer or an Exempt NYLIM Transfer); provided that any Employee
Securities, TCW Securities or NYLIM Securities Transferred pursuant to an
exercise of tag-along rights as an Other Holder under Section 3.3(a) shall
not be subject to the provisions of Section 3.1 in the hands of the
Transferee or any subsequent Transferee; provided, further, any
TCW Securities or NYLIM Securities transferred pursuant to clause (e) of
an Exempt TCW Transfer or an Exempt NYLIM Transfer, as applicable, shall be
treated similar to the TCW Securities or NYLIM Securities in the hands of the
Transferee. All Vestar Securities will continue to be Vestar Securities in the
hands of any Transferee (other than the Company, the Employees or a Transferee
in a Public Sale).

 

3.6                                 Transfers in
Violation of Agreement. Any Transfer or attempted Transfer of any
Securities in violation of any provision of this Agreement shall be void, and
the Company shall not record such Transfer on its books or treat any purported
transferee of such Securities as the owner of such Securities for any purpose.

 

ARTICLE IV

TAKE-ALONG RIGHTS

ON APPROVED SALE

 

4.1                                 Take-Along
Rights.

 

(a) If Vestar elects to
consummate, or to cause the Company to consummate, a transaction constituting a
Sale of the Company, Vestar shall notify the Company and the other
Securityholders in writing of that election, the other Securityholders will
consent to and raise no

 

12

 

objections to the proposed transaction, and the
Securityholders and the Company will take all other actions reasonably
necessary or desirable to cause the consummation of such Sale of the Company on
the terms proposed by Vestar. Without limiting the foregoing, (i) if the
proposed Sale of the Company is structured as a sale of assets or a merger or
consolidation, or otherwise requires equityholder approval pursuant to the LLC
Agreement, the Securityholders and the Company will vote or cause to be voted
all Securities that they hold or with respect to which such Securityholder has
the power to direct the voting and which are entitled to vote on such
transaction in favor of such transaction and will waive any appraisal rights
which they may have in connection therewith and (ii) if the proposed Sale
of the Company is structured as or involves a sale or redemption of Securities,
the Securityholders will agree to sell their pro-rata share of the Securities
being sold in such Sale of the Company on the terms and conditions approved by
Vestar, and the Securityholders will execute any merger, asset purchase,
security purchase, recapitalization or other sale agreement approved by Vestar in
connection with such Sale of the Company.

 

(b)                                 The obligations
of the Securityholders with respect to the Sale of the Company are subject to
the satisfaction of the following conditions:

 

(i)                                     upon the
consummation of the Sale of the Company, all of the holders of a particular
class or series of Securities (if any consideration is to be received by such
holders) shall receive the same form and amount of consideration per share,
unit or amount of Securities (for purpose of this Section 4.1, the Common
Units shall be treated as a single class, provided that the proceeds to be
received by the holders thereof shall take into account any differences in
distribution rights with respect to the Class A Units, Class B Units,
Class C Units and other Units constituting Common Units pursuant to
Article IV of the LLC Agreement), or if any holders of a particular class
or series of Securities are given an option as to the form and amount of
consideration to be received, all holders of such class or series will be given
the same option;

 

(ii)                                  if
consideration is to be received by holders of Securities, all holders of rights
(without regard to time vesting, but giving effect to performance vesting that
is contingent upon the return realized in connection with such sale) to acquire
a particular class or series of Securities will be given an opportunity to
either (A) exercise such rights prior to the consummation of the Sale of
the Company and participate in such sale as holders of such Securities or (B) upon
the consummation of the Sale of the Company, receive in exchange for such
rights consideration equal to the amount determined by multiplying (1) the
same amount of consideration per share, unit or amount of Securities received
by the holders of such type and class of Securities in connection with the Sale
of the Company less the exercise price (or limitation on distribution rights,
if any) per share, unit or amount of such rights to acquire such Securities by
(2) the number of shares, units or aggregate amount of Securities represented
by such rights;

 

(iii)                               if
consideration is to be received by holders of Securities, the holders of
Preferred Units or, as the case may be, Preferred Stock, shall receive
consideration in respect of all of the issued and outstanding shares of Preferred
Units or, as the case may be, Preferred Stock equal to the amount of
consideration that such

 

13

 

holders would have received
if the aggregate consideration for such Sale of the Company had been distributed
by the Company in complete liquidation pursuant to the rights and preferences
set forth in the LLC Agreement as in effect immediately prior to such Sale of
the Company;

 

(iv)                              each
Securityholder shall pay its pro rata share (determined in proportion to net
proceeds received by such Securityholder in connection with such Sale of the
Company) of the expenses incurred in connection with the Sale of the Company;
and

 

(v)                                 liability for
each Securityholder shall be several and not joint with any other Person and
shall be limited to such Securityholder’s pro rata share (determined in
proportion to net proceeds received by such Securityholder in connection with
such Sale of the Company) of a negotiated aggregate indemnification amount or
other obligation (including, without limitation any amount to be held in escrow
in connection with such Sale of the Company) that applies pro rata to all
Securityholders but that in no event exceeds the amount of net proceeds
actually paid to such Securityholder in connection with such Sale of the
Company.

 

(c)                                  Each
Securityholder will bear its or his pro-rata share (based upon the relative
amount of Securities sold) of the reasonable and customary costs of any sale of
Securities pursuant to a Sale of the Company to the extent such costs are
incurred for the benefit of all Securityholders and are not otherwise paid by
the Company or the acquiring party (it being understood that the reasonable and
documented legal fees of one counsel for the holders of Employee Securities up
to a cap as determined by the Company’s management committee prior to the Sale
of the Company shall be deemed costs for the benefit of all Securityholders).
Costs incurred by or on behalf of a Securityholder for its or his sole benefit
will not be considered costs of the transaction hereunder. In the event that
any transaction that Vestar elects to consummate or cause to be consummated
pursuant to this Section 4.1 is not consummated for any
reason, the Company will reimburse Vestar for all actual and reasonable expenses
paid or incurred by Vestar in connection therewith.

 

(d)                                 Notwithstanding
any provision in this Agreement to the contrary, Vestar Capital Partners shall
be entitled to be paid pursuant to the Management Agreement customary and
reasonable fees by the Company and/or its Subsidiaries for any investment
banking services or other services provided by it, including, without
limitation, in connection with a Sale of the Company.

 

(e)                                  In the event of
a sale or exchange by the Securityholders of all or substantially all of the
Securities held by the Securityholders (whether by sale, merger,
recapitalization, reorganization, consolidation, combination or otherwise),
each Securityholder shall receive in exchange for the Securities held by such
Securityholder the same portion of the aggregate consideration from such sale
or exchange that such Securityholder would have received if such aggregate
consideration had been distributed by the Company in complete liquidation
pursuant to the rights and preferences set forth in the LLC Agreement as in
effect immediately prior to such sale or exchange. Each Securityholder shall
take all necessary or

 

14

 

desirable actions in connection with the
distribution of the aggregate consideration from such sale or exchange as
requested by the Company.

 

(f)                                    Any action by
Vestar contemplated by this Article IV shall be deemed to have been taken
by Vestar if such action is taken by the Vestar Majority Holders.

Registrations.

 

(a)                                  Requests for
Registration. Subject to the provisions of this Article V,
the holders of a majority of Vestar Securities that constitute Registrable
Securities shall have the right (the “Vestar Demand Right”), and the
Executive Holders holding a majority of such holders’ Employee Securities that
constitute Registrable Securities shall have the right (the “Employee Demand
Right” and, together with the Vestar Demand Right, the “Demand
Registration Rights”), in each case, to request registration under the
Securities Act of all or any portion of their Registrable Securities on Form S-1
or any similar long-form registration (“Long- Form Demand
Registration”) or on Form S-3 or any similar short-form registration (“Short-Form Demand
Registration”), if such registration is available to the Company, by
delivering a written notice to the principal business office of the Company,
which notice identifies the Requesting Holders and specifies the number of
Registrable Securities to be included in such registration (the “Registration
Request”). Subject to the restrictions set forth in Section 5.1(d),
the Company will give prompt written notice of such Registration Request (the “Registration
Notice”) to all other holders of Registrable Securities and will thereupon
use its reasonable best efforts to effect the registration (a “Demand
Registration”) under the Securities Act on any form available to the
Company of:

 

(i)                                     Registrable
Securities that the Requesting Holders shall have requested to be included in
such offering pursuant to exercise of their Demand Registration Rights;

 

(ii)                                  Securities that
the Company proposes to offer and sell for its own account;

 

(iii)                               all other
Registrable Securities of the same type and class which the Company has received
a written request to register within 20 days after the Registration Notice is
given pursuant to Section 5.2(a); and

 

(iv)                              any Securities
proposed to be included in such registration by holders of registration rights
granted other than pursuant to this Agreement (“Other Registration
Right”), provided that the Company has complied with Section 5.1(f) hereof.

 

Holders of Securities
requesting Demand Registration pursuant to this Section 5.1 or Incidental
Registration pursuant to Section 5.2 are referred to as “Requesting
Holders”.

 

(b)                                 Preservation of
Demand Registration. A registration undertaken by the Company at the
request of the Requesting Holder will not count as a Demand Registration:

 

15

 

(i)                                     if, pursuant to
the Vestar Demand Right or the Employee Demand Right, the Requesting Holders
fail to register and sell at least 85% of the Registrable Securities requested
to be included in such registration by them; or

 

(ii)                                  if the
Requesting Holders withdraw a Registration Request (A) upon the
determination of the Board to postpone the filing or effectiveness of a
Registration Statement pursuant to Section 5.1(d) or (B) within ten days of receiving
notice from the Company of its intent to exercise its Priority Right in
connection with such registration.

 

(c)                                  Priority on
Demand Registration. If the sole or managing underwriter of a Demand
Registration advises the Company in writing that in its opinion the number of
Registrable Securities and other securities requested to be included exceeds
the maximum number of Registrable Securities and other securities (the “Underwriter’s
Maximum Number”) which can be sold in such offering without adversely
affecting the distribution of the securities being offered, the price that will
be paid in such offering or the marketability thereof, then the Company shall
be required to include in such registration only such number of securities as
is equal to the Underwriter’s Maximum Number (the “Demand Registration
Cutback”) and the Company and the holders of Registrable Securities shall
participate in such offering in the following order of priority:

 

(i)                                     first, there
shall be included in such registration that number of Registrable Securities
that the Requesting Holders shall have requested to be included in such
offering pursuant to either Section 5.1(a) or Section 5.2(a),
and that does not exceed the Underwriter’s Maximum Number; provided, however,
that holders who request registration pursuant to Section 5.2(a) shall
not be entitled to participate in any such registration if (x) the sole or
managing underwriter (or, in the case of an offering that is not underwritten,
an investment banker) shall determine in good faith that the participation of
such holders would adversely affect the marketability of the Securities being
sold in such registration and (y) Dr. Dosoretz has approved the
exclusion of such holders based upon the determination of the sole or managing
underwriter (or, in the case of an offering that is not underwritten, an investment
banker), which approval shall not be unreasonably withheld;

 

(ii)                                  second, the
Company shall be entitled to include in such registration that number of
Securities that it proposes to offer and sell for its own account to the full
extent of the remaining portion of the Underwriter’s Maximum Number; and

 

(iii)                               third, the
number of Securities that other holders shall have requested to be included in
such registration pursuant to Other Registration Rights, to the full extent of
the remaining portion of the Underwriter’s Maximum Number; provided,  however,
that such other holders shall not be entitled to participate in any such
registration if the sole or managing underwriter (or, in the case of an
offering that is not underwritten, an investment banker) shall determine in
good faith that the participation of other holders would adversely affect the
marketability of the Securities being sold in such registration.

 

16

 

In the event that a Demand
Registration Cutback results in less than all of the Securities of a particular
category (i.e., Registrable
Securities of the Requesting Holders pursuant to clause (i) above;
Securities of the Company pursuant to clause (ii) above; and Securities of
other holders pursuant to clause (iii) above) that are requested to be
included in such registration actually being included in such registration,
then the number of Securities of such category that shall be included in such
registration shall be allocated pro rata among all of the holders of Securities
of such category that requested Securities to be included in such registration
based on the relative number of shares of securities owned by each such Person.

 

(d)                                 Restrictions on
Demand Registrations. Except as otherwise provided in this Section 5.1(d),
the Company shall be obligated to effect (i) three Long-Form Demand
Registrations and (ii) unlimited Short-Form Demand Registrations to
the extent the Company is a registrant entitled to file a registration
statement on Form S-3 or any successor or similar short-form registration
statement, in each case pursuant to a Vestar Demand Right. The Company shall
not be obligated to effect an Employee Demand Right until after the first
anniversary of the date of the Company’s first Public Offering. Thereafter, the
Company shall be obligated to effect (x) one Long-Form Demand
Registration and (y) one Short-Form Demand Registration per year to
the extent the Company is a registrant entitled to file a registration
statement on Form S-3 or any successor or similar short-form registration
statement, in each case pursuant to an Employee Demand Right. Any Demand
Registration requested must be for a firmly underwritten public offering of
Registrable Securities with an expected value of at least $10 million to be
managed by an underwriter or underwriters of recognized national standing
selected by the Requesting Holders and reasonably acceptable to the Company.
The Company may delay effecting a Demand Registration if after a request is
made, the Company has determined in good faith that the filing of a
registration request would require disclosure of material information which the
Company has a bona fide business purpose for preserving as confidential, the
Company shall not be obligated to effect the registration until the earlier of
(A) the date upon which such material information is disclosed to the
public or is no longer material or (B) 120 days after the Company first
makes such good faith determination.

 

(e)                                  Stock Splits. In connection
with any Demand Registration pursuant to this Section 5.1, each party to
this Agreement will vote, or cause to be voted, all securities of the Company
over which it has the power to vote or direct the voting to effect any stock
split which, in the opinion of the sole or managing underwriter, is necessary
to facilitate the effectiveness of such Demand Registration.

 

(f)                                    Restriction on
Other Registration Rights. Except as provided in this Agreement, the
Company shall not grant to any Persons the right to request the Company to
register any equity securities of the Company, or any securities convertible or
exchangeable into or exercisable for such securities, without the prior written
consent of the holders of at least a majority of the Registrable Securities;
provided that the Company may grant rights to other Persons to participate in
Incidental Registrations so long as such rights are subordinate to the rights
of the holders of Registrable Securities with respect to such Incidental
Registrations.

 

17

 

5.2                                 Incidental
Registration.

 

(a)                                  Requests for
Incidental Registration. At any time the Company proposes to
register any shares of Securities under the Securities Act (other than
registrations on such form(s) solely for registration of Securities in
connection with any employee benefit plan or dividend reinvestment plan or a
merger or consolidation), including registrations pursuant to Section 5.1(a),
whether or not for sale for its own account, the Company will give written
notice to each holder of Registrable Securities at least thirty (30) days prior
to the initial filing of such Registration Statement with the SEC of its intent
to file such registration statement and of such holder’s rights under this
Section 5.2. Upon the written request of any holder of Registrable
Securities made within twenty (20) days after any such notice is given (which
request shall specify the Registrable Securities intended to be disposed of by
such holder), the Company will use its reasonable best efforts to effect the
registration (an “Incidental Registration”) under the Securities Act of
all Registrable Securities which the Company, as the case may be, has been so
requested to register by the holders thereof; provided, however,
that if, at any time after giving written notice of its intention to register
any securities and prior to the effective date of the Registration Statement
filed in connection with such Incidental Registration (each an “Incidental
Registration Statement”), the Company shall determine for any reason not to
register or to delay registration of such securities, the Company may, at its
election, give written notice of such determination to each holder of
Registrable Securities and, thereupon, (i) in the case of a determination
not to register, the Company shall be relieved of its obligation to register
any Registrable Securities under this Section 5.2 in connection with such
registration (but not from its obligation to pay the expenses incurred in
connection therewith), and (ii) in the case of a determination to delay
registration, the Company shall be permitted to delay registering any
Registrable Securities under this Section 5.2 during the period that the
registration of such other securities is delayed.

 

(b)                                 Priority on
Incidental Registration. In connection with any registration not
involving a Demand Registration Cutback, if the sole or managing underwriter of
a registration advises the Company in writing that in its opinion the number of
Registrable Securities and other securities requested to be included exceeds
the number of Registrable Securities and other securities which can be sold in
such offering without adversely affecting the distribution of the securities
being offered, the price that will be paid in such offering or the
marketability thereof, the Company will include in such registration the
Registrable Securities and other securities of the Company in the following
order of priority:

 

(i)                                     first, the
greatest number of Securities of the Company proposed to be included in such
registration by the Company for its own account and by holders of Other
Registration Rights that have priority over the incidental registration rights
granted to holders of Registrable Securities under this Agreement, if any,
which in the opinion of such underwriters can be so sold;

 

(ii)                                  second, after
all Securities that the Company proposes to register for its own account or for
the accounts of holders of Other Registration Rights that have priority over
the incidental registration rights under this Agreement have been included, the
greatest amount of Registrable Securities and Securities having Other
Registration Rights that are pari passu with Registrable Securities, if any, in
each case requested to be registered by the holders thereof which in the
opinion of such underwriters can be sold in such offering without adversely
affecting the distribution of the securities being offered,

 

18

 

the price that will be paid
in such offering or the marketability thereof, ratably among the holders of
Registrable Securities and Securities subject to such Other Registration rights
that are pari passu based on the respective amounts of Registrable Securities
and securities subject to such Other Registration Rights owned by each such holder;
and

 

(iii)                               third, any
other Securities.

 

(c)                                  Upon delivering
a request under this Section 5.2, a Securityholder (excluding Vestar and
its Affiliates, but including any other Permitted Transferee thereof) will, if
requested by the Company, execute and deliver a custody agreement and power of
attorney in form and substance reasonably satisfactory to the Company and one
of the Vestar Managers with respect to such Securityholder’s Securities to be
registered pursuant to this Section 5.2 (a “Custody Agreement and Power
of Attorney”). The Custody Agreement and Power of Attorney will provide,
among other things, that the Securityholder will deliver to and deposit in
custody with the custodian and attorney-in-fact named therein (who shall be
reasonably satisfactory to at least one of the Vestar Managers) a certificate
or certificates representing such Securities (duly endorsed in blank by the
registered owner or owners thereof or accompanied by duly executed stock powers
in blank) and irrevocably appoint said custodian and attorney-in-fact with full
power and authority to act under the Custody Agreement and Power of Attorney on
such Securityholder’s behalf with respect to the matters specified therein.
Such Securityholder also agrees to execute such other agreements as the Company
may reasonably request to further evidence the provisions of this Section 5.2.

 

5.3                                 Holdback
Agreements.

 

(a)                                  Each holder of
Registrable Securities agrees that if requested in connection with an
underwritten offering made pursuant to a Registration Statement for which such
Securityholder has registration rights pursuant to this Article V by the
managing underwriter or underwriters of such underwritten offering, such holder
will not effect any Public Sale or distribution of any of the securities being
registered or any securities convertible or exchangeable or exercisable for
such securities (except as part of such underwritten offering or pursuant to
any Rule 10b-5 trading plan then in effect), during the period beginning
ten (10) days prior to, and ending (i) with respect to the initial
Public Offering, 180 days after, and (ii) with respect to any underwritten
offering subsequent to the initial Public Offering, 90 days after (or, if
approved by the Vestar Majority Holders, a longer period up to 180 days after),
the closing date of the underwritten offering made pursuant to such
Registration Statement (or for such shorter period as to which the managing
underwriter or underwriters may agree, provided that such shorter period
applies equally to all holders of Registrable Securities).

 

(b)                                 The Company
agrees (i) not to effect any public sale or distribution of its equity
securities, or any securities convertible into or exchangeable or exercisable
for such securities, during the seven days prior to and during (x) with
respect to the initial Public Offering, the 180-day period, and (ii) with
respect to any underwritten offering subsequent to the initial Public Offering,
the 90-day period (or, if approved by the Vestar Majority Holders, a longer period
up to 180 days), in each case beginning on the effective date of any
underwritten Demand Registration (or for such shorter period as to which the
managing underwriter or underwriters may agree), except as part of such Demand
Registration or in connection with any

 

19

 

employee benefit or similar plan, any dividend
reinvestment plan, or a business acquisition or combination and (ii) to
use all reasonable efforts to cause each holder of at least 5% (on a fully-
diluted basis) of its equity securities, or any securities convertible into or
exchangeable or exercisable for such securities, which are or may be purchased
from the Company at any time after the date of this Agreement (other than in a
registered offering) to agree not to effect any sale or distribution of any
such securities during such period (except as part of such underwritten
offering, if otherwise permitted).

 

5.4                                 Registration
Procedures. In connection with the registration of any Registrable
Securities or a sale of securities pursuant to an effective shelf registration
statement, as applicable, the Company shall effect such registrations or sales
to permit the sale of such Registrable Securities in accordance with the
intended method or methods of disposition thereof, and pursuant thereto the
Company shall as expeditiously as possible:

 

(a)                                  Prepare and
file with the SEC a Registration Statement or Registration Statements on a form
available for the sale of the Registrable Securities by the holders thereof in
accordance with the intended method of distribution thereof, and use its
reasonable best efforts to cause each such Registration Statement to become
effective;

 

(b)                                 Prepare and
file with the SEC such amendments and post-effective amendments to each
Registration Statement as may be necessary to keep such Registration Statement
continuously effective for a period ending on the earlier of (i) ninety
(90) days from the effective date and (ii) such time as all of such
securities have been disposed of in accordance with the intended method of
disposition thereof; cause the related prospectus to be supplemented by any
required prospectus supplement, and as so supplemented to be filed pursuant to
Rule 424 (or any similar provisions then in force) under the Securities
Act; and comply with the provisions of the Securities Act, the Exchange Act and
the rules and regulations of the SEC promulgated thereunder applicable to
it with respect to the disposition of all securities covered by such
Registration Statement as so amended or in such prospectus as so supplemented.

 

(c)                                  Notify the
selling holders of Registrable Securities promptly (but in any event within two
business days), and confirm such notice in writing, (i) when a prospectus
or any prospectus supplement or post-effective amendment has been filed, and,
with respect to a Registration Statement or any post-effective amendment, when
the same has become effective, (ii) of the issuance by the SEC of any stop
order suspending the effectiveness of a Registration Statement or of any order
preventing or suspending the use of any preliminary prospectus, (iii) if
at any time when a prospectus is required by the Securities Act to be delivered
in connection with sales of Registrable Securities the Company becomes aware
that the representations and warranties of the Company contained in any
agreement (including any underwriting agreement) contemplated by Section 5.4(h) below
cease to be true and correct in all material respects, (iv) of the receipt
by the Company of any notification with respect to the suspension of the
qualification or exemption from qualification of a Registration Statement or
any of the Registrable Securities for offer or sale in any jurisdiction or (v) if
the Company becomes aware of the happening of any event that makes any
statement made in such Registration Statement or related prospectus or any
document incorporated or deemed to be incorporated therein by reference untrue
in any material respect or that requires the making of any changes in such
Registration Statement, prospectus or documents so that, in the case of such
Registration Statement, it will not contain any untrue

 

20

 

statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading, and that in the case of the prospectus, it will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading.

 

(d)                                 Use its
reasonable best efforts to prevent the issuance of any order suspending the
effectiveness of a Registration Statement or of any order preventing or
suspending the use of a prospectus or suspending the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in
any jurisdiction, and, if any such order is issued, to obtain the withdrawal of
any such order at the earliest possible moment.

 

(e)                                  Deliver to each
selling holder of Registrable Securities and the underwriters, if any, without
charge, as many copies of the prospectus or prospectuses (including each form
of prospectus) and each amendment or supplement thereto as such Persons may
reasonably request; and the Company hereby consents to the use of such
prospectus and each amendment or supplement thereto by each of the selling
holders of Registrable Securities and the underwriters or agents, if any, in
connection with the offering and sale of the Registrable Securities covered by
such prospectus and any amendment or supplement thereto.

 

(f)                                    Prior to any
public offering of Registrable Securities, to use its reasonable best efforts
to register or qualify, and cooperate with the selling holders of Registrable
Securities, the underwriters, if any, the sales agents and their respective
counsel in connection with the registration or qualification (or exemption from
such registration or qualification) of such Registrable Securities for offer
and sale under the securities or “blue sky” laws of such jurisdictions within
the United States as any selling holder or the managing underwriters reasonably
request in writing; provided, however, that the Company will not be required to
(i) qualify generally to do business in any jurisdiction where it is not then
so qualified or (ii) take any action that would subject it to general
service of process in any such jurisdiction where it is not then so subject.

 

(g)                                 Upon the occurrence
of any event contemplated by Section 5.4(c)(v) above, as promptly as
practicable prepare a supplement or post-effective amendment to the
Registration Statement or a supplement to the related prospectus or any
document incorporated or deemed to be incorporated therein by reference, or
file any other required document so that, as thereafter delivered to the
purchasers of the Registrable Securities being sold thereunder, such prospectus
will not contain 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, in light of the circumstances under which they were made, not
misleading.

 

(h)                                 Enter into an
underwriting agreement in form, scope and substance as is customary in
underwritten offerings and take all such other actions as are reasonably
requested by the managing or sole underwriter in order to expedite or
facilitate the registration or the disposition of such Registrable Securities,
and in such connection, (i) make such representations and warranties to
the underwriters, with respect to the business of the Company and its
subsidiaries, and the Registration Statement, prospectus and documents, if any,
incorporated or deemed to be incorporated by reference therein, in each case,
in form, substance and scope as are

 

21

 

customarily made by issuers to underwriters in
underwritten offerings, and confirm the same if and when requested; (ii) obtain
opinions of counsel to the Company and updates thereof (which counsel and
opinions (in form, scope and substance) shall be reasonably satisfactory to the
managing underwriters), addressed to the underwriters covering the matters
customarily covered in opinions requested in underwritten offerings and such
other matters as may be reasonably requested by underwriters; (iii) obtain
“cold comfort” letters and updates thereof from the independent certified
public accountants of the Company (and, if necessary, any other independent certified
public accountants of any Subsidiary of the Company or of any business acquired
by the Company for which financial statements and financial data are, or are
required to be, included in the Registration Statement), addressed to each of
the underwriters, such letters to be in customary form and covering matters of
the type customarily covered in “cold comfort” letters in connection with
underwritten offerings; and (iv) if an underwriting agreement is entered
into, the same shall contain indemnification provisions and procedures no less
favorable to the holders of Registrable Securities than those set forth in
Section 5.7 hereof (or such other provisions and procedures acceptable to
holders of a majority of the Registrable Securities covered by such Registration
Statement and the managing underwriters or agents) with respect to all parties
to be indemnified pursuant to said Section. The above shall be done at each
closing under such underwriting agreement, or as and to the extent required
thereunder.

 

(i)                                     Comply with all
applicable rules and regulations of the SEC and make generally available
to its Securityholders earnings statements satisfying the provisions of Section 11(a) of
the Securities Act and Rule 158 thereunder (or any similar rule promulgated
under the Securities Act) no later than forty-five (45) days after the end of
any 12-month period (or ninety (90) days after the end of any 12-month period
if such period is a fiscal year) (i) commencing at the end of any fiscal
quarter in which Registrable Securities are sold to underwriters in a firm
commitment or reasonable best efforts underwritten offering and (ii) if
not sold to underwriters in such an offering, commencing on the first day of
the first fiscal quarter of the Company after the effectiveness of a
Registration Statement, which statements shall cover said 12-month periods.

 

(j)                                     (i) Use
its reasonable best efforts to cause all such Registrable Securities covered by
such registration statement to be listed on the principal securities exchange
on which Common Stock is then listed (if any), if the listing of such
Registrable Securities is then permitted under the rules of such exchange,
or (ii) if no Common Stock is then so listed, use its reasonable best
efforts to cause all such Registrable Securities to be listed on a national
securities exchange and, without limiting the generality of the foregoing, to
arrange for at least two market makers to register as such with respect to such
shares with the National Association of Securities Dealers, Inc. (“NASD”).

 

The Company may require each
holder of Registrable Securities as to which any registration is being effected
to furnish to the Company such information regarding such holder and the
distribution of such Registrable Securities as the Company may, from time to
time, reasonably request in writing and the Company shall be entitled to rely
on such information provided; provided that such information shall be used only
in connection with such registration. The Company may exclude from such registration
the Registrable Securities of any holder who unreasonably fails to furnish such
information promptly after receiving such request. Each holder agrees that,
upon receipt of any notice from the Company of the happening of any event

 

22

 

of the kind described in Section 5.4(c)(ii),
5.4(c)(iv) or 5.4(c)(v), such holder will forthwith discontinue
disposition of such Registrable Securities covered by such Registration
Statement or prospectus until such holder’s receipt of the copies of the
supplemented or amended prospectus contemplated by Section 5.4, or until
it is advised in writing by the Company that the use of the applicable
prospectus may be resumed, and has received copies of any amendments or
supplements thereto.

 

5.5                                 Shelf
Registration. Subject to the provisions set forth in Section 5.4,
if the holders of a majority of Vestar Securities that constitute Registrable
Securities so specify, or if the Executive Holders holding a majority of such
holders’ Employee Securities that constitute Registrable Securities so specify,
in the Registration Notice that they desire the Company to undertake a shelf
registration of some or all of such Registrable Securities, then the Company
shall file with the SEC a registration statement under the Securities Act on
the appropriate form pursuant to Rule 415 under the Securities Act (the “Required
Registration”). The Company shall use its reasonable best efforts to cause
the Required Registration to be declared effective under the Securities Act as
soon as practical after filing, and once effective, the Company shall cause
such Required Registration to remain effective for a period ending on the
earlier of (i) the second anniversary of the effectiveness thereof, (ii) the
date on which all Registrable Securities have been sold pursuant to the
Required Registration and (iii) the date as of which there are no longer
any Registrable Securities in existence.

 

5.6                                 Registration
Expenses. Subject to Section 5.1(b)(i), all fees and
expenses incident to the performance of or compliance with this Agreement by
the Company shall be borne by the Company, whether or not any Registration
Statement is filed or becomes effective, including, without limitation, (i) all
registration and filing fees (including, without limitation, (A) fees with
respect to filings required to be made with the NASD in connection with an underwritten
offering and (B) fees and

messenger, telephone and delivery expenses, (iii) fees and disbursements
of counsel for the Company, (iv) fees and disbursements of all independent
certified public accountants referred to in Section 5.4(h), (v) underwriters’
fees and expenses (excluding discounts, commissions, or fees of underwriters,
selling brokers, dealer managers or similar securities industry professionals
relating to the distribution of the Registrable Securities), (vi) Securities
Act liability insurance, if the Company so desires such insurance, (vii) internal
expenses of the Company, (viii) the expense of any annual audit, (ix) the

with any Demand Registration or Incidental Registration hereunder, the Company
shall reimburse the holders of the Registrable Securities being registered in
such registration for the reasonable fees and disbursements of not more than
one counsel (together with appropriate local counsel) chosen by the Requesting
Holders, if pursuant to a Demand Registration, or the Company, in all other
cases, and other reasonable out-of-pocket expenses of the holders of
Registrable Securities incurred in connection with the registration of the
Registrable Securities.

5.7                              Indemnification;
Contribution.

 

(a)                                  Indemnification
by the Company. The Company shall, without limitation as to time,
indemnify and hold harmless, to the full extent permitted by law, each holder
of Registrable Securities, the officers, directors, agents and employees of
each of them, each Person who controls each such holder (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act),
the officers, directors, agents and employees of each such controlling person
and any financial or investment adviser (each, an “Indemnified Party”),
to the fullest extent lawful, from and against any and all losses, claims,
damages, liabilities, actions or proceedings (whether commenced or threatened)
reasonable costs (including, without limitation, reasonable costs of
preparation and reasonable attorneys’ fees) and reasonable expenses (including
reasonable expenses of investigation) (collectively, “Losses”), as
incurred, arising out of or based upon (i) any untrue or alleged untrue
statement of a material fact contained in any Registration Statement,
prospectus or form of prospectus or in any amendment or supplements thereto or
in any preliminary prospectus, or arising out of or based upon any omission or
alleged omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading, except to the extent that the
same arise out of or are based upon information furnished in writing to the
Company by such Indemnified Party or the related holder of Registrable
Securities expressly for use therein or (ii) any violation by the Company
of any federal, state or common law rule or regulation applicable to the
Company and relating to action required of or inaction by the Company in
connection with any such registration; provided, however, that the Company
shall 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 underwriters within the meaning of the Securities Act to the
extent that any such Losses arise out of or are based upon an untrue statement
or alleged untrue statement or omission or alleged omission made in any
preliminary prospectus if (i) such Person failed to send or deliver a copy
of the prospectus with or prior to the delivery of written confirmation of the
sale by such Person to the Person asserting the claim from which such Losses
arise, (ii) the prospectus would have corrected such untrue statement or
alleged untrue statement or such omission or alleged omission, and (iii) the
Company has complied with its obligations under Section 5.4(c). Each
indemnity and reimbursement of costs and expenses shall remain in full force
and effect regardless of any investigation made by or on behalf of such
indemnified party.

 

(b)                                 Indemnification
by Holders. In connection with any Registration Statement in
which a holder of Registrable Securities is participating, such holder, or an
authorized officer of such holder, shall furnish to the Company in writing such
information as the Company reasonably requests for use in connection with any
Registration Statement or prospectus and agrees, severally and not jointly, to
indemnify, to the full extent permitted by law, the Company, its directors,
officers, agents and employees, each Person who controls the Company (within
the meaning of Section 15 of the Securities Act and Section 20 of the
Exchange Act), and the directors, officers, agents or employees of such
controlling persons, from and against all Losses arising out of or based upon
any untrue or alleged untrue statement of a material fact contained in any
Registration Statement, prospectus, or form of prospectus, or arising out of or
based upon any omission or alleged omission of a material fact required to be
stated therein or necessary to make the statements therein not misleading, to
the extent, but only to the extent, that such untrue or alleged untrue
statement is contained in, or such omission or alleged omission is required to
be contained in, any information so furnished in writing by such holder to the
Company expressly for use in such Registration Statement or prospectus and that
such statement or omission was relied upon by the Company in preparation of
such Registration

 

24

 

Statement, prospectus or form of prospectus;
provided, however, that such holder of Registrable Securities shall not be
liable in any such case to the extent that the holder has furnished in writing
to the Company within a reasonable period of time prior to the filing of any
such Registration Statement or prospectus or amendment or supplement thereto
information expressly for use in such Registration Statement or prospectus or
any amendment or supplement thereto which corrected or made not misleading,
information previously furnished to the Company, and the Company failed to include
such information therein. In no event shall the liability of any selling holder
of Registrable Securities hereunder be greater in amount than the dollar amount
of the proceeds (net of payment of all expenses) received by such holder upon
the sale of the Registrable Securities giving rise to such indemnification
obligation. Such indemnity shall remain in full force and effect regardless of
any investigation made by or on behalf of such indemnified party.

 

(c)                                  Conduct of
Indemnification Proceedings. If any Person shall be
entitled to indemnity hereunder (an “indemnified party”), such
indemnified party shall give prompt notice to the party or parties from which
such indemnity is sought (the “indemnifying parties”) of the
commencement of any action, suit, proceeding or investigation or written threat
thereof (a “Proceeding”) with respect to which such indemnified party
seeks indemnification or contribution pursuant hereto; provided, however, that
the failure to so notify the indemnifying parties shall not relieve the
indemnifying parties from any obligation or liability except to the extent that
the indemnifying parties have been prejudiced by such failure. The indemnifying
parties shall have the right, exercisable by giving written notice to an
indemnified party promptly after the receipt of written notice from such
indemnified party of such Proceeding, to assume, at the indemnifying parties’
expense, the defense of any such Proceeding, with counsel reasonably
satisfactory to such indemnified party; provided, however, that
an indemnified party or parties (if more than one such indemnified party is
named in any Proceeding) shall have the right to employ separate counsel in any
such Proceeding and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party or
parties unless: (i) the indemnifying parties agree to pay such fees and
expenses; (ii) the indemnifying parties fail promptly to assume the
defense of such Proceeding or fail to employ counsel reasonably satisfactory to
such indemnified party or parties; or (iii) the named parties to any such
Proceeding (including any impleaded parties) include both such indemnified
party or parties and the indemnifying parties or an affiliate of the indemnifying
parties or such indemnified parties, and there may be one or more defenses
available to such indemnified party or parties that are different from or
additional to those available to the indemnifying parties, in which case, if
such indemnified party or parties notifies the indemnifying parties in writing
that it elects to employ separate counsel at the expense of the indemnifying
parties, the indemnifying parties shall not have the right to assume the
defense thereof and such counsel shall be at the expense of the indemnifying
parties, it being understood, however, that, unless there exists a conflict
among indemnified parties, the indemnifying parties shall not, in connection
with any one such Proceeding or separate but substantially similar or related
Proceedings in the same jurisdiction, arising out of the same general
allegations or circumstances, be liable for the fees and expenses of more than
one separate firm of attorneys (together with appropriate local counsel) at any
time for such indemnified party or parties. Whether or not such defense is
assumed by the indemnifying parties, such indemnifying parties or indemnified
party or parties will not be subject to any liability for any settlement made
without its or their consent (but such consent will not be unreasonably
withheld). The indemnifying parties shall not consent to entry of any

 

25

 

judgment or enter into any settlement which (i) provides
for other than monetary damages without the consent of the indemnified party or
parties (which consent shall not be unreasonably withheld or delayed) or (ii) does
not include as an unconditional term thereof the giving by the claimant or
plaintiff to such indemnified party or parties of a release, in form and
substance satisfactory to the indemnified party or parties, from all liability
in respect of such Proceeding for which such indemnified party would be
entitled to indemnification hereunder.

 

(d)                                 Contribution. If the
indemnification provided for in this Section 5.7 is unavailable to an
indemnified party or is insufficient to hold such indemnified party harmless
for any Losses in respect of which this Section 5.6 would otherwise apply
by its terms, then each applicable indemnifying party, in lieu of indemnifying
such indemnified party, shall have an obligation to contribute to the amount
paid or payable by such indemnified party as a result of such Losses, in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party, on the one hand, and such indemnified party, on the other hand, in
connection with the actions, statements or omissions that resulted in such
Losses as well as any other relevant equitable considerations. The relative
fault of such indemnifying party, on the one hand, and indemnified party, on
the other hand, shall be determined by reference to, among other things,
whether any action in question, including any untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact, has been taken by, or relates to information supplied by, such
indemnifying party or indemnified party, and the parties’ relative intent,
knowledge, access to information and opportunity to correct or prevent any such
action, statement or omission. The amount paid or payable by a party as a
result of any Losses shall be deemed to include any legal or other fees or
expenses incurred by such party in connection with any Proceeding, to the
extent such party would have been indemnified for such expenses if the
indemnification provided for in Section 5.7(a) or 5.7(b) was
available to such party. The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 5.7(d) were
determined by pro-rata allocation or by any other method of allocation that
does not take account of the equitable considerations referred to in this
Section 5.7(d). Notwithstanding the provisions of this Section 5.7(d),
an indemnifying party that is a selling holder of Registrable Securities shall
not be required to contribute any amount in excess of the amount by which the
net proceeds received by such indemnifying party exceeds the amount of any
damages that such indemnifying party has otherwise been required to pay by
reasons of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution
from any Person who was not guilty of such fraudulent misrepresentation.

 

5.8                                 Rules 144
and 144A. At all times after the Company effects its initial
Public Offering, the Company shall file the reports required to be filed by it
under the Securities Act and the Exchange Act and the rules and
regulations promulgated thereunder (or, if the Company is not required to file
such reports, it will, upon the request of any holder of Registrable
Securities, make publicly available other information so long as such
information is necessary to permit sales under Rule 144A), and will take
such further action as any holder of Registrable Securities may reasonably
request, all to the extent required from time to time to enable such holder to
sell Registrable Securities without registration under the Securities Act
within the limitation of the exemptions provided by Rule 144 and Rule 144A.
Upon the request of any holder of Registrable Securities, the Company shall
deliver to such holder a written statement as to whether it has complied with
such requirements.

 

26

 

5.9                                 Underwritten
Registrations. No holder of Registrable Securities may participate
in any underwritten registration hereunder unless such holder (a) agrees
to sell such holder’s Registrable Securities on the basis provided in any
underwriting arrangements approved by the Persons entitled hereunder to approve
such arrangements and (b) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
required under the terms of such underwriting arrangements.

 

5.10                           No Inconsistent
Agreements. The Company has not and will not, enter into any
agreement with respect to the Company’s securities that is inconsistent with
the rights granted to the holders of Registrable Securities in this Article V
or otherwise conflicts with the provisions hereof.

 

ARTICLE VI

VENTURE CAPITAL OPERATING COMPANY

 

6.1                                 VCOC
Securityholders.

 

(a)                                  Each of Vestar
V, Vestar V-A and Vestar/RTI is intended to qualify as a “venture capital
operating company” as defined in the Plan Asset Regulations (each, a “VCOC
Securityholder”). For so long as the VCOC Securityholder, directly or through
one or more conduit Subsidiaries, continues to hold any Units (or other
securities of the Company into which such Units may be converted or for which
such Units may be exchanged), without limitation or prejudice of any the rights
provided to the Securityholders hereunder, the Company shall, with respect to
each such VCOC Securityholder:

 

(i)                                     Provide each
VCOC Securityholder or its designated representative with:

 

(A)                              the right to
visit and inspect any of the offices and properties of the Company and its
Subsidiaries and inspect and copy the books and records of the Company and its
Subsidiaries, as the VCOC Securityholder shall reasonably request;

 

(B)                                as soon as
available and in any event within 45 days after the end of each of the first
three quarters of each fiscal year of the Company, consolidated balance sheets
of the Company and its Subsidiaries as of the end of such period, and
consolidated statements of income and cash flows of the Company and its
Subsidiaries for the period then ended prepared in conformity with generally
accepted accounting principles in the United States applied on a consistent
basis, except as otherwise noted therein, and subject to the absence of
footnotes and to year-end adjustments;

 

(C)                                as soon as
available and in any event within 90 days after the end of each fiscal year of
the Company, a consolidated balance sheet of the Company and its Subsidiaries
as of the end of such year, and consolidated statements of income and cash
flows of the Company and its Subsidiaries for the year then ended prepared in
conformity with generally accepted accounting principles in the United States
applied on a consistent basis, except as otherwise

 

27

 

noted therein, together with an auditor’s report
thereon of a firm of established national reputation;

 

(D)                                    to the extent
the Company or any of its Subsidiaries is required by law or pursuant to the
terms of any outstanding indebtedness of the Company or such Subsidiary to
prepare such reports, any annual reports, quarterly reports and other periodic
reports pursuant to Section 13 or 15(d) of the Exchange Act, actually
prepared by the Company or such Subsidiary as soon as available; and

 

(E)                                     copies of all materials
provided to the Board, and if requested, copies of all materials provided to
the board of directors (or similar organization body) of the Company’s
Subsidiaries, provided, that the Company shall be entitled to exclude portions
of such materials to the extent providing such portions would be reasonably
likely to result in the waiver of attorney-client privilege.

 

(ii)                                  Make
appropriate directors and officers of the Company, and its subsidiaries,
available periodically and at such times as reasonably requested by the VCOC
Securityholder for consultation with the VCOC Securityholder or its designated
representative with respect to matters relating to the business and affairs of
the Company and its Subsidiaries, including significant changes in management
personnel and compensation of employees, introduction of new products or new
lines of business, important acquisitions or dispositions of plants and
equipment, significant research and development programs, the purchasing or
selling of important trademarks, licenses or concessions or the proposed
commencement or compromise of significant litigation;

 

(iii)                               Give the VCOC
Securityholder the right to designate one non-voting board observer who will be
entitled to attend all meetings of the Company’s Board, participate in all
deliberations of the Board and receive copies of all materials provided to the
Board, provided that such observer shall have no voting rights with respect to
actions taken or elected not to be taken by the Board, and provided, further, that
the Company shall be entitled to exclude such observer from such portions of a
board meeting to the extent such observer’s presence would be reasonably likely
to result in the waiver of attorney-client privilege;

 

(iv)                              To the extent
consistent with applicable law (and with respect to events which require public
disclosure, only following the Company’s public disclosure thereof through
applicable securities law filings or otherwise), inform the VCOC Securityholder
or its designated representative in advance with respect to any significant
corporate actions, including extraordinary dividends, mergers, acquisitions or
dispositions of assets, issuances of significant amounts of debt or equity and
material amendments to the organizational documents of the Company, and to
provide the VCOC Securityholder or its designated representative with the right
to consult with the Company with respect to such actions; and

 

28

 

(v)                            Provide the
VCOC Securityholder or its designated representative with such other rights of
consultation which the VCOC Securityholder’s counsel may determine to be
reasonably necessary under applicable legal authorities promulgated after the
date hereof to qualify its investment in the Company as a “venture capital
investment” for purposes of the Plan Assets Regulation.

 

(b)                                 The Company
agrees to consider, in good faith, the recommendations of each VCOC
Securityholder or its designated representative in connection with the matters
on which it is consulted as described above, recognizing that the ultimate
discretion with respect to all such matters shall be retained by the Company.

 

(c)                                  In the event
that the Company ceases to qualify as an “operating company” (within the
meaning of the first sentence of 29 C.F.R. Section 2510.3-101(c)(1) of
the Plan Asset Regulations), then the Company and each Securityholder will
cooperate in good faith to take all reasonable action necessary to provide that
the investment (or at least 51% of the investment valued at cost) of each VCOC
Securityholder shall continue to qualify as a “venture capital investment” (as
defined in the Plan Asset Regulations).

 

ARTICLE VII

AMENDMENT AND TERMINATION

 

7.1                                    Amendment and
Waiver. Except as otherwise provided herein, no modification, amendment or
waiver of any provision of this Agreement shall be effective against the
Company or the Securityholders unless such modification, amendment or waiver is
approved in writing by each of the Company and Vestar Majority Holders;
provided that no such modification, amendment or waiver may change the rights
or obligations hereunder of holders of Employee Securities, TCW Securities or
NYLIM Securities in a manner that is material and adverse unless approved in
writing by the Employee Majority Holders, the TCW Majority Holders or the NYLIM
Majority Holders, respectively. 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.

 

7.2                                    Termination of
Agreement. This Agreement will terminate in respect of all
Securityholders (a) with the written consent of the Company, the Vestar
Majority Holders, the Employee Majority Holders, the TCW Majority Holders and
the NYLIM Majority Holders, (b) upon the dissolution, liquidation or
winding-up of the Company or (c) upon the consummation of a transaction,
whether in a single transaction or in a series of related transactions that are
consummated contemporaneously (or consummated pursuant to contemporaneous
agreements), with any other Person or Persons on an arms-length basis, pursuant
to which such party or parties acquire (whether by merger, stock purchase,
recapitalization, reorganization, redemption, issuance of capital stock or
otherwise) more than 50% of the Class A Units or voting securities of the
Company. The termination of this Agreement will not affect any indemnification
or contribution obligations under Section 5.6, which shall survive such
termination.

 

29

 

7.3                                    Termination as
to a Party. Any Person who ceases to hold any Securities shall
cease to be a Securityholder and shall have no further rights or obligations
under this Agreement (except with respect to any indemnification and
contribution obligations under Section 5.6, which shall survive).

 

7.4                                    Issuer of
Registrable Securities. Prior to distributing to the holders of Units
all or substantially all of the securities of any direct or indirect Subsidiary
of the Company, the Company shall cause such Subsidiary to execute and deliver
a Stockholders Agreement complying with this Section 7.4 (the “Stockholders
Agreement”), and each Person, other than the Company, that is a party to
this Agreement shall execute and deliver the Stockholders Agreement. The
Stockholders Agreement shall be substantially identical to this Agreement,
including the provisions that are applicable to an issuer of Registrable
Securities hereunder, except that it shall be revised so that such issuer
replaces the Company hereunder with respect to provisions that are applicable
to the Company hereunder, and such other revisions shall be made as are
necessary or desirable to reflect the fact that the issuer is a corporation
rather than a limited liability company. In addition, if the issuer has
consummated its initial Public Offering, then any provision of this Agreement
that, pursuant to the terms of this Agreement, terminates upon a initial Public
Offering shall be excluded from the Stockholders Agreement, and, in any event,
this Section 7.4 shall not be included in the Stockholders
Agreement.

 

ARTICLE VIII

PARTICIPATION RIGHTS

 

8.1                                    Participation
Right. In the event the Company proposes to sell or issue New Units (as
defined in Section 8.2 hereof) in one transaction or a series of related
transactions, each holder of Class A Units (a “Class A Holder”)
shall have the right (the “Participation Right”) to irrevocably
subscribe for a pro rata portion of the New Units to be offered in such
proposed sale. A Class A Holder’s pro rata portion of the New Units for
purposes of this Section 8.1 is (x) the aggregate number of New Units
multiplied by (y) the number of outstanding Class A Units such Class A
Holder then owns divided by (z) the total number of Class A Units
then outstanding. To the extent any New Units subject to Participation Rights
shall remain unsubscribed for after exercise by the Class A Holders of
their participation right pursuant to this Section 8.1, Vestar shall have
the right to purchase such remaining New Units, provided that no Participation
Right shall arise as a result of such purchase by Vestar. If any New Units
subject to Participation Rights shall remain unsubscribed for after the Class A
Holders and Vestar have exercised their respective rights pursuant to this
Section 8.1(a), the Company shall have one hundred eighty (180) days
thereafter to sell such remaining New Units, at a price and upon terms no more
favorable to the purchasers thereof than specified in the Company’s notice
given pursuant to Section 8.3.

 

8.2                                    Definition of
New Units. “New Units” shall mean any (i) Units,
or (ii) any warrants, rights, calls, options or other securities
exchangeable for or exercisable or convertible into units or any other security
entitled to participate in the Company’s profits, in each case to be issued by
the Company to any Person; provided, that New Units shall not include any type
of security distributed to Securityholders as a dividend or distribution in
accordance with Section 4.1 of the LLC Agreement.

 

30

 

8.3                                    Notice from the
Company. In the event the Company proposes to undertake an issuance of New
Units, the Company shall give each Class A Holder written notice of such
proposal (the “Sale Participation Notice”), describing the type of New
Units and the price and the terms and conditions upon which the Company
proposes to issue the same, and setting forth the pro rata portion of the New
Units that such Class A Holder is entitled to purchase pursuant to its
Participation Right. For a period of twenty (20) business days following the
receipt of such notice from the Company, the Company shall be deemed to have
irrevocably offered to sell to each Class A Holder such number of New
Units as set forth above for the price and upon the terms specified in the
notice. Each Class A Holder may irrevocably exercise its Participation
Right hereunder by giving written notice to the Company and stating therein the
quantity of New Units to be purchased within twenty (20) business days
following the receipt of the Sale Participation Notice from the Company.

 

8.4                                    Closing. The closing
of any such issuance or sale to a Class A Holder shall take place as
proposed by the Company with respect to the New Units to be issued or sold no
earlier than twenty (20) days after the Company receives notice of the exercise
of the Participation Right but no later than sixty (60) days after the issuance
of the New Units with respect to which such Participation Right was exercised,
at which closing the Company shall deliver certificates for the New Units (if
the Units are evidenced by certificates) in the name of such Class A
Holder against receipt of the consideration therefor. If the consideration for
the New Units is other than cash, the Class A Holder shall be entitled to
deliver cash in lieu thereof in an amount equal to the Fair Market Value of
such non-cash consideration.

 

8.5                                    Compliance. Nothing in
this Section 8 shall be deemed to prevent any Person from purchasing any
New Units without the Company first complying with the provisions of Section 8.1;
provided that in connection with such purchase (a) the Company gives
prompt notice of such purchase to each Class A Holder, but in any event
within thirty (30) days after such purchase, which notice shall describe in
reasonable detail the New Units being issued and the purchase price thereof,
and (b) the purchasers in such issuance (the “Purchasers”) and the
Company take all steps reasonably necessary to enable each Class A Holder
to effectively exercise its Participation Right with respect to the purchase of
a pro rata share of the New Units issued to the Purchasers after such purchase
by the Purchasers on the terms specified in this Section 8 within sixty
(60) days thereafter.

 

8.6                               Exempted Issuances. The
provisions of Sections 8.1 through Section 8.5 above shall not apply to
the following issuances of Securities:

 

(a)                                      any Securities
issued in connection with the exercise, conversion or exchange of any
Securities of the Company that were not issued in violation of this Section 8,
any subdivision of Securities (including any dividend or split), any
combination of Securities (including any reverse split) or any recapitalization,
reorganization or reclassification of the Company.

 

(b)                                      any Securities
issued to employees, officers, directors, consultants and other service
providers of or to the Company or any of its Subsidiaries (other than Vestar or
any of its Affiliates) in exchange for services pursuant to any agreement or
arrangement approved by the Board;

 

31

 

(c)                                       any securities
issued to third party lenders as “equity kickers” in connection with what is
primarily a loan transaction pursuant to any agreement or arrangement approved
by the Board; and

 

(d)                                      any securities
issued to the sellers or a comparable party in connection with an acquisition,

Company (as amended from time to time in accordance with its terms, the “LLC
Agreement”).

 

WHEREAS,
the Executive is an employee and shareholder of Radiation Therapy Services, a

WHEREAS,
RTS has entered into an Agreement and Plan of Merger with Radiation Therapy
Services Holdings, Inc., a Delaware corporation and a wholly-owned subsidiary
of the Company (“Holdings”), RTS MergerCo, Inc., a Florida corporation
and wholly owned subsidiary of Holdings (“Merger Sub”), and the Company,
dated as of October 19, 2007 (as amended from time to time in accordance with
its terms, the “Merger Agreement”), pursuant to which Merger Sub shall
be merged with and into RTS (the “Acquisition”) in accordance with the
terms and conditions of the Merger Agreement and the relevant provisions of the
Florida Business Corporation Act, and RTS shall be the surviving corporation in
the Acquisition and a wholly-owned subsidiary of Holdings;

 

WHEREAS,
prior to the consummation of the transactions contemplated by this Agreement
and the Merger Agreement, the Executive is the record and beneficial owner of
the number of shares of RTS’ common stock, par value $0.0001 per share (the “Shares”),
set forth on Schedule I attached hereto; and

 

WHEREAS,
on the terms and subject to the conditions hereof and pursuant to Section
721(a) of the United States Internal Revenue Code of 1986, as amended (the “Code”),
the Executive desires to contribute certain of the Shares in exchange for the
Preferred Units (the “Preferred Units”) and Class A Units (the “Class
A Units”) in the Company, in each case in the amounts set forth on Schedule
II attached hereto.

 

NOW,
THEREFORE, in order to implement the foregoing and in consideration of the

continued failure of such Executive to substantially perform the material
duties (including, without limitation, full cooperation in any audit or

required of him (except termination due to death or permanent disability) after
demand for performance is delivered by the Board, in writing, specifically
identifying the manner in which the Board in good faith determines that such
Executive has not performed his material obligations and such Executive fails
to perform as required within 20 days after such demand is made;
(iii) conviction of such Executive of any willful and material violation

if no such agreement containing a definition of “Disability” is then in effect,
shall mean the inability of the Executive to perform the essential functions of
Executive’s job, with or without reasonable accommodation, by reason of a
physical or mental infirmity, for a continuous period of six months.  The period of six months shall be deemed
continuous unless Executive returns to work for at least 30 consecutive
business days during such period and performs during such period at the level
and competence that existed prior to the beginning of the six-month
period.  The date of such Disability shall
be on the first day of such six-month period.

 

1.16.        Employee and Employment.  The term “employee” shall mean any

(valuing the Company and its subsidiaries as a going concern; disregarding any
discount for minority interest, non-voting interest or marketability of the
Units, whether due to transfer restrictions or the lack of a public market for
the Units; taking into account the Preferred Return (as defined in the LLC
Agreement)); provided further that if the Executive
disagrees in good faith with the Board’s determination and the aggregate Fair
Market 

 

3

 

Value of the Units in question is asserted in good
faith by the Executive to be in excess of $1,000,000, the Executive shall
promptly notify the Company in writing of such disagreement within 15 business
days of receipt of the Board’s determination of the Fair Market Value of such
Units, in which event an independent appraiser, accountant or investment
banking firm (the “Arbiter”) shall be selected by mutual agreement of
the Executive and the Board within 15 days of the Company’s receipt of the
Executive’s notice of disagreement.  The
Arbiter shall make a determination of the Fair Market Value thereof (valuing
the Company and its subsidiaries as set forth above) solely by (i) reviewing a
single written presentation (together with any supporting documentation) timely
made by each of the Company and the Executive setting forth their respective
valuations and the bases therefor and (ii) accepting either the Executive’s or
the Company’s proposed valuation.  For
the avoidance of doubt, the determination of Fair Market Value of any Unit
shall be based on the amounts that would be distributable in respect of such
Unit upon a Sale of the Company under the terms of the LLC Agreement,
including, without limitation, any adjustments necessary to reflect the portion
of any tax distributions that were previously made in respect of such Unit but
not charged against other distributions in respect of such Unit.  In the event the Executive and the Board are
unable to agree on an Arbiter that is mutually acceptable to both parties

5.1.          Call Options.

 

(a)           If the Executive’s
employment with the Company or any of its subsidiaries terminates for any of
the reasons set forth in clauses (i), (ii) or (iii) below prior to a
Sale of the Company, or if the Executive engages in any Prohibited Activity
during the time that such activity is prohibited, the Company shall have the
right and option to purchase for a period of 90 days following the Termination
Date (provided that if the Executive’s employment with the Company and its
subsidiaries is terminated prior to the six month anniversary of the Closing
Date, such 90 day period shall begin on the six month anniversary of the
Closing Date) (such period, the “Call Option Exercise Period”), and each
member of the Executive Group shall be required to sell to the Company, any or
all of the Rollover Units then held by such member of the Executive Group (it
being understood that if the Rollover Units of any class subject to repurchase
hereunder may be repurchased at different prices, the Company may elect to
repurchase only the portion of Rollover Units of such class subject to
repurchase hereunder at the lower price), at a price per Unit equal to the
applicable purchase price determined pursuant to Section 5.1(c):

 

(i)            if the Executive’s active
employment with the Company and its subsidiaries is terminated due to the
Disability or death of the Executive;

employment with the Company and its subsidiaries is terminated (A) by the

11

 

(b)           If the Company desires to
exercise one of its options to purchase Units pursuant to this Section 5.1,
the Company shall, not later than the expiration of the applicable Call Option
Exercise Period, send written notice to each member of the Executive Group of
its intention to purchase all or a portion of the Rollover Units, specifying
the number of Rollover Units to be purchased and the Fair Market Value of the
Rollover Units as of the date of such notice (the “Call Notice”).  Subject to the provisions of Section 6,
the closing of the purchase shall take place at the principal office of the
Company on the later of the 30th day after the giving of the Call Notice and
the date that is 10 business days after the final determination of Fair Market
Value.  Subject to the provisions of Section 6,
the Executive shall deliver to the Company duly executed instruments
transferring title to Units to the Company, against payment of the appropriate
purchase price by cashier’s or certified check payable to the Executive or by
wire transfer of immediately available funds to an account designated by the
Executive.

 

(c)           In the event of a purchase
by the Company pursuant to Section 5.1(a), the purchase price shall
be (in each case after taking account of any prior purchases pursuant to Section 5.1(a)):

 

(i)            if the Executive engages in
Prohibited Activity, a price per Unit equal to the Fair Market Value measured
as of the Activity Date; and

 

(ii)           in the case of a termination
of employment described in Section 5.1(a)(i), Section 5.1(a)(ii),
or Section 5.1(a)(iii), a price per Unit equal to the Fair Market
Value measured as of the date of the Call Notice.

 

(d)           If (i) the Company
exercises its option to purchase the Units pursuant to this Section 5.1
upon a termination of employment described in Section 5.1(a)(i) or
Section 5.1(a)(ii), (ii) within six months following the date
of closing of such purchase, a Sale of the Company occurs resulting in the
unitholders receiving cash proceeds from such sale, and (iii) the cash
proceeds per Unit that would have been received by the Executive with respect
to any Units that were repurchased had the Executive continued to hold such
Units through the closing of such Sale of the Company would have been greater
than the purchase price determined pursuant to Section 5.1(c)(ii) above,
then in connection with the consummation of such Sale of the Company, the
Executive shall be entitled to receive an amount in cash equal to the product
of (x) the number of Rollover Units purchased by the Company pursuant to
this Section 5.1 and (y) the amount by which the cash proceeds
per each such Unit that would have been so received in connection with such
Sale of the Company exceeds the purchase price paid by the Company pursuant to Section 5.1(c)(ii) above.

 

(e)           Notwithstanding anything to
the contrary contained in this Agreement, if the Fair Market Value of Units
subject to a Call Notice is finally determined to be an amount at least 15%
greater than the per Unit repurchase price for such Unit in the Call Notice,
the Company shall have the right to revoke the exercise of its option pursuant
to this Section 5.1 for all or any portion of the Units elected to
be repurchased by it by delivering notice of such revocation in writing to the
Executive Group during the ten-day period beginning on the date that the
Company is given written notice that the Fair Market Value of a Unit was
finally determined to be an amount at least 15% greater than the per Unit
repurchase price set forth in the Call Notice.

 

12

 

5.2.          Obligation to Sell Several.  If there is more than one member of the
Executive Group, the failure of any one member thereof to perform its obligations
hereunder shall not excuse or affect the obligations of any other member
thereof, and the closing of the purchases from such other members by the
Company shall not excuse, or constitute a waiver of its rights against, the
defaulting member.

 

5.3.          Interim Distributions.  Notwithstanding anything to the contrary
herein, in the event the Company declares or a pays a distribution with respect
to any of the Units held by the Executive Group on or after the Termination
Date but prior to the exercise by the Company of the call option provided by Section 5.1
or prior to the closing of the repurchase transactions contemplated by a Call
Notice, the entire portion of such distribution shall be held in escrow by the
Company (such amounts, the “Escrow Funds”) until the later of (i) the
expiry of the time period by which the call option provided by Section 5.1
must be exercised and (ii) if one or more Call Notices have been
delivered, until all the transactions contemplated by all Call Notices have
been consummated.  In the event the
Company decides to exercise the call option provided by Section 5.1,
the entire amount of such Escrow Funds shall be permanently transferred to the
Company and deemed forfeited by the Executive Group.  In the event the Company does not exercise
the call option provided by Section 5.1, the entire amount of such
Escrow Funds shall be permanently transferred to the relevant members of the
Executive Group.

 

6.             Certain Limitations on the
Company’s Obligations to Purchase Units.

 

6.1.          Payment for Units.  If at any time the Company elects or is
required to purchase any Units pursuant to Section 5, the Company
shall pay the purchase price for the Units it purchases (i) first, by
offsetting indebtedness, if any, owing from the Executive to the Company (which
indebtedness shall be applied pro rata against the proceeds receivable by each
member of the Executive Group receiving consideration in such repurchase) and (ii) then,
by the Company’ delivery of a check or wire transfer of immediately available funds
for the remainder of the purchase price (if any) against delivery of the
certificates or other instruments representing the Units so purchased, duly
endorsed; provided that the Company shall not be required to make such cash
payment if such cash payment would result in (A) a violation of any law,
statute, rule, regulation, policy, order, writ, injunction, decree or judgment
promulgated or entered by any federal, state, local or foreign court or
governmental authority applicable to the Company or any of its subsidiaries or
any of its or their property, or (B) after giving effect thereto, a
Financing Default, or if the Board determines in good faith that immediately
prior to such purchase there shall exist a Financing Default which prohibits
such purchase, dividend or distribution (any such restriction, a “Payment
Restriction”).  If such a Payment
Restriction exists, the Company will use all commercially reasonable efforts to
cause the party to whom the obligation is owed giving rise to such Payment
Restriction to waive such Payment Restriction so that such cash payment may be
made or, if no party is involved in such restriction, to otherwise eliminate
such Payment Restriction; provided that the Company shall not have any
obligation to make a payment to any party or to modify any agreement, contract
or other arrangement in a manner that is material and adverse to the Company or
any of its subsidiaries in order to eliminate such restriction.  The Company will use its reasonable
discretion to determine the timing of such request or requests to waive or
remove such Payment Restriction.  If such
Payment Restriction is not waived or removed or if the Executive’s employment
is terminated by the Company for Cause, at the Company’s election, the Company
may pay such purchase price in the form of a junior

 

13

 

subordinated note of the Company (a “Junior
Subordinated Note”) (or partially in cash, to the extent such partial cash
payment is not so prohibited) bearing interest at (A) a rate equal to the “prime
rate” (as published in The Wall Street Journal on the date of issuance) plus
two basis points, compounded annually, if the Executive’s employment was
terminated for the reasons set forth in Section 5.1(a)(i) or 5.1(a)(ii) and
the Company exercises its repurchase option pursuant to Section 5.1,
or (B) at the Applicable Federal Rate, compounded annually, if Executive’s
employment was terminated for the reasons set forth in Section 5.1(a)(iii) and
the Company exercises its repurchase option pursuant to Section 5.1.  The principal and interest with respect to
such note shall be payable within a 10 business day period after the earliest
to occur of (w) the date on which such Payment Restriction no longer
exists, (x) the date of the initial Public Offering, (y) the date on
which the Company makes a distribution pursuant to Section 4.1 of the LLC
Agreement (other than a tax distribution), or (z) upon a Sale of the
Company from net cash proceeds, if any, payable to the Company or its
unitholders; to the extent that sufficient net cash proceeds are not so
payable, the Junior Subordinated Note shall be cancelled in exchange for such
other non-cash consideration received by unitholders in the Sale of the Company
having a Fair Market Value equal to the principal of and accrued interest on
the note.  The principal of and accrued
interest on any such note may be prepaid in whole or in part at any time at the
option of the Company.  In the event a
Junior Subordinated Note is issued in respect of the purchase price for any
Units purchased by the Company pursuant to Section 5, the Company
shall grant to the Executive a first priority security interest in such Units
as collateral security for the prompt and complete payment when due of the note
and the interest thereon, and shall use commercially reasonable efforts to
assist the Executive to perfect such security interest in the Units.

 

6.2.          Certain Deferral of Payment.  If, at the closing of any purchase of Units
pursuant to Section 5, the Company has not opted to issue a Junior
Subordinated Note pursuant to Sections 6.1 (or is prohibited from doing
so), and any such purchase would result in a material and adverse accounting or
tax effect for the Company or violation or breach of any financing agreement to
which the Company is a party, then the Company will provide written notice to
the Executive explaining in reasonable detail such adverse effects and such
closing of the purchase pursuant to Section 5 shall not be
consummated until such time as it can be done without such adverse effect; provided
that in no event shall such deferral exceed one (1) year; provided,
further, that the Executive shall be entitled to interest on the amount
to be paid for such Units at the rate that would be applicable if a Junior
Subordinated Note had been issued in accordance with Sections 6.1 for
the period of such deferral.

 

7.             Additional Covenants by the
Executive.

 

7.1.          Prohibited Activities.  For so long as Executive is employed by the
Company and continuing for twenty-four (24) months thereafter, Executive shall
not engage in Competitive Activity.

 

7.2.          Protection of Confidential
Information.  The
Executive agrees that he will keep all confidential and proprietary information
of the Company or relating to its business (including, but not limited to,
information regarding the Company’s customers, pricing policies, methods of
operation, proprietary computer programs and trade secrets) confidential, and
that he will not (except with the Company’s prior written consent), while in
the employ of the Company or at any time thereafter, disclose any such
confidential information to any person, firm, corporation,

 

14

 

association or other entity, other than in
furtherance of his duties hereunder, and then only to those with a “need to
know.” The Executive shall not make use of any such confidential information
for his own purposes or for the benefit of any person, firm, corporation,
association or other entity (except the Company) under any circumstances during
or at any time after the term of his employment.  The foregoing shall not apply to any
information which is already in the public domain, or is generally disclosed by
the Company or is otherwise in the public domain at the time of disclosure,
except if such information is in the public domain as a result of the Executive’s
actions in contravention of this Section 7.2.  The Executive recognizes that because his
work for the Company will bring him into contact with confidential and
proprietary information of the Company, the restrictions of this Section 7.2
are required for the reasonable protection of the Company and its investments
and for the Company’s reliance on and confidence in the Executive.

 

8.             Miscellaneous.

 

8.1.          Transfers to Permitted
Transferees.  Prior to
the transfer of Units to a Permitted Transferee (other than a transfer in
connection with or subsequent to a Sale of the Company), the Executive shall
deliver to the Company a written agreement of the proposed transferee (a) evidencing
such Person’s undertaking to be bound by the terms of this Agreement and (b) acknowledging
that the Units transferred to such Person will continue to be Units for
purposes of this Agreement in the hands of such Person.  Any transfer or attempted transfer of Units
in violation of any provision of this Agreement or the Securityholders
Agreement shall be void, and the Company shall not record such transfer on its
books or treat any purported transferee of such Units as the owner of such
Units for any purpose.

 

8.2.          Deemed Transfer of Units.  If the Company shall deliver, at the time and
place and in the amount and form provided in this Agreement, the consideration
for the Units to be repurchased in accordance with the provisions of this Agreement,
then from and after such time, the Person from whom such Units are to be
repurchased shall no longer have any rights as a holder of such Units (other
than the right to receive payment of such consideration in accordance with this
Agreement), and such Units shall be deemed purchased in accordance with the
applicable provisions hereof and the Company shall be deemed the owner and
holder of such Units, whether or not certificates therefor have been delivered
as required by this Agreement.

 

8.3.          Recapitalizations, Exchanges, Etc.,
Affecting Units.  The
provisions of this Agreement shall apply, to the full extent set forth herein
with respect to Units, to any and all securities of the Company or any
successor or assign of the Company (whether by merger, consolidation, sale of
assets or otherwise) which may be issued in respect of, in exchange for, or in
substitution of the Units, by reason of any dividend payable in Units, issuance
of Units, combination, recapitalization, reclassification, merger, consolidation
or otherwise.

 

8.4.          Executive’s Employment by
the Company.  Nothing
contained in this Agreement shall be deemed to obligate the Company or any
subsidiary of the Company to employ the Executive in any capacity whatsoever or
to prohibit or restrict the Company (or any such subsidiary) from terminating
the employment of the Executive at any time or for any reason whatsoever, with
or without Cause.

 

15

 

8.5.          Indemnification by Executive.  Executive agrees to indemnify and hold
harmless the Company against any and all taxes due or paid by Parent or its
subsidiaries incurred in connection with any failure to withhold amounts
relating to the Units acquired herein by the Management Investors.  Each of Executive and the Company shall
notify the other (in a manner described in Section 8.10 of this
Agreement) within 20 days of first receiving notice of an audit or other
proceeding being conducted by the Internal Revenue Service or any state or
local taxing authority relating to the Units acquired herein by the Management
Investors, and both Executive and the Company shall assist each other during
the course of such audit or other proceeding to the extent that such assistance
is reasonably requested.

 

8.6.          Binding Effect.  The provisions of this Agreement shall be
binding upon and accrue to the benefit of the parties hereto and their
respective heirs, legal representatives, successors and assigns; provided,
however, that no Permitted Transferee shall derive any rights under this
Agreement unless and until such Permitted Transferee has executed and delivered
to the Company a valid undertaking and becomes bound by the terms of this
Agreement; and provided  further that Vestar is a third party
beneficiary of this Agreement and shall have the right to enforce the
provisions hereof.

 

8.7.          Amendment; Waiver.  This Agreement may be amended only by a
written instrument signed by the parties hereto.  No waiver by any party hereto of any of the
provisions hereof shall be effective unless set forth in a writing executed by
the party so waiving.

 

8.8.          Governing Law.  This Agreement shall be governed by and
construed and enforced in accordance with the laws of the State of Delaware
applicable to contracts made and to be performed therein.

 

8.9.          Jurisdiction.  Any suit, action or proceeding with respect
to this Agreement, or any judgment entered by any court in respect of any
thereof, shall be brought in any court of competent jurisdiction in the State
of Delaware, and each of the Company and the members of the Executive Group
hereby submits to the exclusive jurisdiction of such courts for the purpose of
any such suit, action, proceeding or judgment. 
Each of the members of the Executive Group and the Company hereby
irrevocably waives any objections which it may now or hereafter have to the
laying of the venue of any suit, action or proceeding arising out of or
relating to this Agreement brought in any court of competent jurisdiction in
the State of Delaware, and hereby further irrevocably waives any claim that any
such suit, action or proceeding brought in any such court has been brought in
any inconvenient forum.

 

8.10.        Notices.  All notices and other communications
hereunder shall be in writing and shall be deemed to have been duly given when
personally delivered, telecopied (with confirmation of receipt), one day after
deposit with a reputable overnight delivery service (charges prepaid) and three
days after deposit in the U.S. Mail (postage prepaid and return receipt
requested) to the address set forth below or such other address as the

8.11.        Integration.  This Agreement and the documents referred to
herein or delivered pursuant hereto which form a part hereof contain the entire
understanding of the parties with respect to the subject matter hereof and
thereof.  There are no restrictions,

8.13.        Injunctive Relief.  Without intending to limit the remedies
available to each of the parties hereto, the Company, the Executive and the
Executive’s Permitted Transferees each acknowledges that a breach of any of the
terms of this Agreement may result in material and irreparable injury for which
there is no adequate remedy at law, that it will not be possible to measure
damages for such injuries precisely and that, in the event of such a breach or
threat thereof, each party hereto shall be entitled to seek a temporary
restraining order and/or preliminary or permanent injunction restraining the
other party (and their Permitted Transferees) from engaging in activities
prohibited by this Agreement or such other relief as may be required
specifically to enforce any of the terms hereof.  If for any reason it is held that the
restrictions under this Agreement are not reasonable or that consideration
therefore is inadequate, such restrictions shall be interpreted or modified to
include as much of the duration and scope identified in this Agreement as will
render such restrictions valid and enforceable.

 

8.14.        WAIVER OF JURY TRIAL.  EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES
ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

 

8.15.        Rights Cumulative; Waiver.  The rights and remedies of the Executive and
the Company under this Agreement shall be cumulative and not exclusive of any
rights or remedies which either would otherwise have hereunder or at law or in
equity or by statute, and no failure or delay by either party in exercising any
right or remedy shall impair any such right or remedy or operate as a waiver of
such right or remedy, nor shall any single or partial exercise of any power or
right preclude such party’s other or further exercise or the exercise of any
other power or right.  The waiver by any
party hereto of a breach of any provision of this Agreement shall not operate
or be construed as a waiver of any preceding or succeeding breach and no
failure by either party to exercise any right or privilege hereunder shall be
deemed a waiver of such party’s rights or privileges hereunder or shall be
deemed a waiver of such party’s rights to exercise the same at any subsequent
time or times hereunder.
