          SECTION 4.01. Officers. The officers of the Company (the “Officers”) shall at
all times be identical to the then officers of CAM. Any changes in the officers of CAM, whether by
election, resignation, removal, death or otherwise, shall automatically and concurrently take
effect with respect to the Officers of the Company. No Officer may resign unless such Officer
concurrently resigns as an officer of CAM. Any resignation by an Officer shall constitute such

10

 

          SECTION 4.02. Management Policies. The Officers and employees of the Company shall
develop and implement management policies consistent with the general policies and programs

DISTRIBUTIONS

          SECTION 5.01. Distributions. (a) The Manager, in its discretion, may authorize
distributions by the Company to the Members pro rata in accordance with their respective Ownership
Interests. 

          (b)(i) Notwithstanding the foregoing, if the Manager reasonably determines that the Net
Profits of the Company for a Fiscal Year will give rise to net taxable income for the Members
(after giving effect to cumulative Net Losses from prior Fiscal Years available to offset such Net
Profits), the Manager shall cause the Company to distribute available cash for purposes of allowing
the Members to fund their respective income tax liabilities (the “Tax Advances”). The Tax
Advances payable with respect to any Fiscal Year shall be computed based upon the Manager’s
estimate of the net taxable income attributable to Net Profits of the Company for such Fiscal Year
(after giving effect to cumulative Net Losses from prior Fiscal Years available to offset such Net
Profits), multiplied by the highest combined tax rate (federal, state and local, taking into
account any deductions of state or local taxes against federal tax liability) applicable to any
Member or, in the case of CFP, any of its shareholders, taking into account the character of the
taxable income for tax purposes (the “Tax Amount”). For purposes of computing the Tax
Amount, the effect of any benefit to a Member under Section 743 of the Code, if any, will be
ignored. Tax Advances shall be distributed to the Members on a pro rata basis in accordance with
their respective Ownership Interests, but in no event shall the distributed amount exceed the
available cash of the Company, as determined in the reasonable discretion of the Manager.

          (ii) Tax Advances shall be calculated and paid no later than one day prior to each quarterly
due date for the payment of estimated taxes under the Code in the following manner: (i) for the
first quarterly period, 25% of the Tax Amount, (ii) for the second quarterly period, 50% of the Tax
Amount, less the prior Tax Advances for the Fiscal Year, (iii) for the third quarterly period, 75%
of the Tax Amount, less the prior Tax Advances for the Fiscal year and (iv) for the fourth
quarterly period, 100% of the Tax Amount, less the prior Tax Advances for the Fiscal Year.
Following each Fiscal Year, and no later than one day prior to the due date for the payment by
individuals or corporations, whichever is earlier, of income taxes for such Fiscal Year under the
Code, the Manager shall make a final calculation of the Tax Amount for such Fiscal Year (the
“Final Tax Amount”), and shall cause the Company to distribute a Tax Advance, subject to
the availability of cash, to the extent that the Final Tax Amount so calculated exceeds the
cumulative Tax Advances previously made by the Company in respect of such Fiscal Year. If the
Final Tax Amount is less than the cumulative Tax Advances previously made by the Company in respect
of the relevant Fiscal Year, then the difference (the “Credit Amount”) shall be applied
against, and shall reduce, the amount of Tax Advances made to the Members for subsequent Fiscal
Years. Any Credit Amount applied against future Tax Advances shall be treated as an amount
actually distributed pursuant to this Section 5.01(b) for purposes of the computations herein.

11

 

          (iii) Any Tax Advances made to a Member pursuant to this Section 5.01(b) shall be repaid to
the Company by reducing the amount of the next succeeding distribution or distributions which would
otherwise have been made to such Member pursuant to Section 5.01(a) or 9.03 hereof.

          SECTION 5.02. Liquidation Distribution. Distributions made upon liquidation of the
Company shall be made as provided in Section 9.03.

          SECTION 5.03. Withholding. (a) Each Member hereby authorizes the Company to withhold
from or pay on behalf of or with respect to such Member any amount of federal, state, local or
foreign taxes that the Manager determines that the Company is required to withhold or pay with
respect to any amount distributable or allocable to such Member pursuant to this Agreement,
including any taxes required to be withheld by the Company pursuant to Sections 1441, 1442, 1445 or
1446 of the Code. Any amount paid on behalf of or with respect to a Member shall constitute a loan
by the Company to such Member, which loan shall be repaid by such Member within fifteen (15) days
after notice from the Manager that such payment must be made unless (i) the Company withholds such
payment from a distribution which would otherwise be made to such Member or (ii) the Manager
determines, in its sole discretion, that such payment may be satisfied out of the available funds
of the Company which would, but for such payment, be distributed to such Member. Any withheld
amounts described in clauses (i) and (ii) of the preceding sentence shall be treated as having been
distributed to such Member.

          (b) A Member shall not have the status of, and is not entitled to the remedies available to, a
creditor of the Company with regard to distributions that such Member becomes entitled to receive
pursuant to this Agreement and the Act.

          SECTION 5.04. Limitations on Distribution. Notwithstanding any provision to the
contrary contained in this Agreement, the Company shall not make a distribution to any Member on
account of its Ownership Interests if such distribution would violate Section 18-607 of the Act or
other applicable Law.

ARTICLE VI

12

 

updated from time to time to reflect changes in the information set forth therein accomplished
in accordance with this Agreement, and any such update shall not constitute an amendment to this
Agreement and shall not be subject to Section 11.12 hereof. Ownership Interests in the Company
shall constitute a “security” within the meaning of (i) Article 8 of the Uniform Commercial Code
(including Section 8-102(a)(15) thereof) as in effect from time to time in the State of Delaware,
and (ii) the Uniform Commercial Code of any other applicable jurisdiction that now or hereafter
substantially includes the 1994 revisions to Article 8 thereof as adopted by the American Law

          SECTION 6.04. Members’ Capital Accounts. No Member shall have any right to withdraw
any portion of its Capital Account, except as otherwise provided herein. No interest shall be paid
to any Member with respect to its Capital Contributions. Each Member’s initial Capital Account is
set forth on Schedule I, which initial Capital Accounts apply the principles of Regulation Section
1.704-1(b)(2)(iv)(d) and thereafter such Capital Accounts shall be adjusted as follows:

     (i) The amount of any Net Profits (and any items of income or gain), allocated to such
Member;

     (ii) The amount, if any, of any Company liabilities assumed by such Member or taken
subject to or in connection with the distribution of property to such Member by the Company;

     (iii) The amount of any cash contributed by the Member to the Company; and

     (b) The Capital Account of each Member shall be decreased by:

     (i) The amount of cash distributed to such Member by the Company;

     (ii) The amount of any Net Losses (and any items of deduction or loss) allocated to
such Member;

     (iii) The Asset Value of any property distributed to such Member by the Company; and

     (iv) The amount of any liabilities of such Member assumed by the Company or taken
subject to or in connection with the contribution of property by such Member to the Company.

13

 

The foregoing provisions and the other provisions of this Agreement relating to the maintenance of
Capital Accounts are intended to comply with Regulations under Section 704(b) of the Code
and, to the extent not inconsistent with the provisions of this Agreement, shall be interpreted and
applied in a manner consistent with such Regulations.

          SECTION 6.05. Allocations of Net Profits and Net Losses. Subject to the special
allocations set forth in Sections 6.06 and 6.09 below, Net Profits and Net Losses for each Fiscal
Year shall be allocated among the Members pro rata in accordance with their respective Ownership
Interests.

          SECTION 6.06. Special Allocations. (a) Minimum Gain Chargeback. Except as
otherwise provided in Section 1.704-2(f) of the Regulations, notwithstanding any other provision of
this Article VI, if there is a net decrease in partnership minimum gain during any Fiscal Year,
each Member shall be specially allocated items of Company income and gain for the Fiscal Year (and,
if necessary, subsequent Fiscal Years) in an amount equal to such Member’s share of the net
decrease in partnership minimum gain, determined in accordance with Regulations Section 1.704-2(g).
Allocations pursuant to the previous sentence shall be made in proportion to the respective
amounts required to be allocated to each Member pursuant thereto. The items to be so allocated
shall be determined in accordance with Sections 1.704-2(f)(6) and 1.704-2(j)(2) of the Regulations.
This Section 6.06(a) is intended to comply with the minimum gain chargeback requirement in Section
1.704-2(f) of the Regulations and shall be interpreted consistently therewith.

          (b) Partner Minimum Gain Chargeback. Except as otherwise provided in Section
1.704-2(i)(4) of the Regulations, notwithstanding any other provision of this Article VI, if there
is a net decrease in partner nonrecourse debt minimum gain attributable to a partner nonrecourse
debt during any Fiscal Year, each Member who has a share of the partner nonrecourse debt minimum
gain attributable to such partner nonrecourse debt, determined in accordance with Section
1.704-2(i)(5) of the Regulations, shall be specifically allocated items of Company income and gain
for such Fiscal Year (and, if necessary, subsequent Fiscal Years) in an amount equal to such
Member’s share of the net decrease in partner nonrecourse debt minimum gain attributable to such
partner nonrecourse debt, determined in accordance with Section 1.704-2(i)(4) of the Regulations.
Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts
required to be allocated to each Member pursuant thereto. The items to be so allocated shall be
determined in accordance with Sections 1.704-2(i)(4) and 1.704-2(j)(2) of the Regulations. This
Section 6.06(b) is intended to comply with the minimum gain chargeback requirement in Section
1.704-2(i)(4) of the Regulations and shall be interpreted consistently therewith.

          (c) Qualified Income Offset. In the event any Member unexpectedly receives any
adjustments, allocations or distributions described in Section 1.704-1(b)(2)(ii)(d)(4),
1.704-1(b)(2)(ii)(d)(5) or 1.704-1(b)(2)(ii)(d)(6) of the Regulations, items of Company income and
gain shall be specially allocated to each such Member in an amount and manner sufficient to
eliminate, to the extent required by the Regulations, the Adjusted Capital Account Deficit of such
Member as quickly as possible, provided that an allocation pursuant to this Section 6.06(c) shall
be made only if and to the extent that such Member would have an Adjusted Capital Account Deficit
after all other allocations provided for in this Article VI have been tentatively made as if this
Section 6.06(c) were not in the Agreement.

14

 

          (d) Gross Income Allocation. In the event any Member has a deficit Capital Account at
the end of any Fiscal Year which is in excess of the sum of (i) the amount such Member is obligated
to restore pursuant to any provision of this Agreement, and (ii) the amount such Member is deemed
to be obligated to restore pursuant to the penultimate sentences of Sections 1.704-2(g)(1) and
1.704-2(i)(5) of the Regulations, each such Member shall be specially allocated items of Company
income and gain in the amount of such excess as quickly as possible; provided that an
allocation pursuant to this Section 6.06(d) shall be made only if and to the extent that such
Member would have an Adjusted Capital Account Deficit in excess of such sum after all other
allocations provided for in this Article VI have been made as if Section 6.06(c) and this Section
6.06(d) were not in the Agreement.

          (e) Nonrecourse Deductions. Nonrecourse Deductions for any Fiscal Year shall be
allocated to the Members pro rata in accordance with their respective Ownership Interests.

          (f) Partner Nonrecourse Deductions. Partner Nonrecourse Deductions for any Fiscal
Year shall be specially allocated to the Member who bears the economic risk of loss, or to the
Members in the proportions in which they bear the economic risk of loss, with respect to the
partner nonrecourse debt to which such Partner Nonrecourse Deductions are attributable in
accordance with Regulation Section 1.704-2(i).

          (g) Section 754 Adjustments. To the extent that an adjustment to the adjusted tax
basis of any Company asset under Code Section 734(b) or Code Section 743(b) is required, pursuant
to Regulations Section 1.704-1(b)(2)(iv)(m)(2) or 1.704-1(b)(2)(iv)(m)(4), to be taken into account
in determining Capital Accounts as the result of a distribution to a Member in complete liquidation
of the Membership Interest of such Member, the amount of such adjustment to Capital Accounts shall
be treated as an item of gain (if the adjustment increases the adjusted tax basis of the asset) or
loss (if the adjustment decreases the adjusted tax basis of the asset), and such gain or loss shall
be specially allocated to the Members in accordance with their Percentage Interests if Regulations
Section 1.704-1(b)(2)(iv)(m)(2) applies, or to the Member to whom such distribution was made if
Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies.

          SECTION 6.07. Tax Allocations. (a) In accordance with Code Section 704(c) and the
Regulations thereunder, income, gain, loss, and deduction with respect to any property contributed
to the capital of the Company shall, solely for tax purposes, be allocated among the Members so as
to take account of any variation between the adjusted basis of such property to the Company for
federal income tax purposes and its initial Asset Value (computed in accordance with the definition
of Asset Value).

          (b) In the event the Asset Value of any Company asset is adjusted pursuant to subparagraph
(ii) of the definition of Asset Value, subsequent allocations of income, gain, loss, and deduction
with respect to such asset shall take account of any variation between the adjusted basis of such
asset for federal income tax purposes and its Asset Value in the same manner as under Code Section
704(c) and the Regulations thereunder.

          (c) Any elections or other decisions relating to allocations under this Section 6.07 shall be
made by the Tax Matters Member in any manner that reasonably reflects the purpose and intention of
this Agreement. Allocations pursuant to this Section 6.07 are solely for

15

 

purposes of federal, state, and local taxes and shall not affect, or in any way be taken into
account in computing, any Member’s Capital Account, share of Net Profit, Net Loss or distributions
pursuant to any provision of this Agreement.

          SECTION 6.08. Tax Decisions. CAM shall be the initial “tax matters partner” within
the meaning of Section 6231(a)(7) of the Code (the “Tax Matters Member”). The Company
shall file as a partnership for federal, state and local income tax purposes, except where
otherwise required by Law. All elections required or permitted to be made by the Company, and all
other tax decisions and determinations relating to federal, state or local tax matters of the
Company, shall be made by the Tax Matters Member, in consultation with the Company’s attorneys
and/or accountants. Tax audits, controversies and litigations shall be conducted under the
direction of the Tax Matters Member. The Tax Matters Member shall keep the other Members
reasonably informed as to any tax actions, examinations or proceedings relating to the Company and
shall submit to the other Members, for their review and comment, any settlement or compromise offer
with respect to any disputed item of income, gain, loss, deduction or credit of the Company. As
soon as reasonably practicable after the end of each Fiscal Year, the Company shall send to each
Member a copy of IRS Schedule K-1, and any comparable statements required by applicable state or
local income tax Law, with respect to such Fiscal Year. The Company also shall provide the Members
with such other information as may be reasonably requested for purposes of allowing the Members to
prepare and file their own tax returns.

          SECTION 6.09. Curative Allocations. The allocations set forth in Section 6.06 (the
“Regulatory Allocations”) are intended to comply with certain requirements of the
Regulations. It is the intent of the Members that, to the maximum extent possible, all Regulatory
Allocations shall be offset either with other Regulatory Allocations or with special allocations of
other items of Company income, gain, loss or deduction pursuant to this Section 6.09. Accordingly,
notwithstanding any other provision of this Article VI (other than the Regulatory Allocations), the
Manager shall make such offsetting special allocations of Company income, gain, loss or deduction
in whatever manner the Manager determines appropriate so that, after such offsetting allocations
are made, each Member’s Capital Account balance is, to the extent possible, equal to the Capital
Account balance such Member would have had if the Regulatory Allocations were not part of this
Agreement and all Company items were allocated pursuant to this Article VI without regard to the
Regulatory Allocations. In exercising its discretion under this Section 6.09, the Manager shall
take into account future Regulatory Allocations under Section 6.06 that, although not yet made, are
likely to offset other Regulatory Allocations previously made under Section 6.06.

ARTICLE VII

BOOKS AND RECORDS; REPORTS

          SECTION 7.01. Books and Records. At all times during the continuance of the Company,
the Company shall prepare and maintain separate books of account for the Company that shall show a
true and accurate record of all costs and expenses incurred, all charges made, all credits made and
received and all income derived in connection with the operation of the Company business in
accordance with GAAP. Such books of account shall at all times be

16

 

maintained at the principal place of business of the Company and shall, solely to the extent
required under applicable Law, be open to inspection and examination at reasonable times by each
Member and its duly authorized representatives. Without limiting the foregoing, the Company shall
keep at its principal office the following:

          (a) a current list of the full name and the last known street address of each Member;

          (b) a copy of the Certificate of Formation and this Agreement and all amendments thereto;

          (c) copies of the Company’s federal, state and local income tax returns and reports, if any,
for the three most recent years;

          (d) copies of any financial statements, if any, of the Company for the six most recent Fiscal
Years; and

          (e) such other documents with respect to the Company’s business as may reasonably be required
from time to time by the Manager.

ARTICLE VIII

it is issued and Ownership Interests which such certificate represents. Such certificates shall be
entered in the books of the Company as they are issued, and shall be signed by the Chairman, Chief

for Ownership Interests in place of any certificate or certificates theretofore issued by it,

          SECTION 8.04. Reserved.

          SECTION 8.05. Incentive Plans. At any time CAM issues a share of Class A Common Stock
pursuant to an Incentive Plan (whether pursuant to the exercise of a stock option or the grant of a
restricted share award or otherwise), the following shall occur, notwithstanding anything to the

Common Stock to the Company as a capital contribution; (ii) the value of the capital contribution
shall be equal to the fair market value of shares of Class A Common Stock contributed; (iii) the

          SECTION 8.08. Restrictions on Transfer. Any Transfer of Beneficial Ownership of any
Ownership Interest by CFP or any CFP Permitted Transferee shall be subject to Sections 8.09 and
8.10.

          SECTION 8.09. Permitted Transfers. Notwithstanding anything in this Agreement to the
contrary, each of CFP and any CFP Permitted Transferee may Transfer record or Beneficial Ownership
of some or all of the Ownership Interests Beneficially Owned by it (and any rights it may have
under this Agreement):

          (a) to a CFP Permitted Transferee;

          (b) to CAM in exchange for Class A Common Stock in accordance with the Second Amended and
Restated Certificate of Incorporation; or

     (c) in the case of a CFP Permitted Transferee that is a trustee or other fiduciary,
pursuant to applicable Law or the terms of the trust agreement governing the applicable
trust;

provided, however, that the Manager is reasonably satisfied that the Transfer will
not cause the Company to qualify as a “publicly traded partnership,” as that term is defined in
Section 7704 of the Code; and, provided, further, that neither CFP nor any CFP
Permitted Transferee shall be prohibited from Transferring some or all of the Ownership Interests
held by it (and any rights it may have under this Agreement) in connection with any merger or
consolidation of CAM or the Company, or any transaction having the same effect, that is approved in
accordance with the By-Laws.

          SECTION 8.10. Transfers to Persons other than CFP Permitted Transferees. In the event
that Beneficial Ownership of Ownership Interests is Transferred to any Person that is not a CFP
Permitted Transferee (other than to CAM in exchange for Class A Common Stock in accordance with the
Second Amended and Restated Certificate of Incorporation), until such time, if any, that such
Ownership Interests become Beneficially Owned by a CFP Permitted Transferee, (a) the record holder
of such Transferred Ownership Interests shall cease to exercise any rights or powers of a Member
(other than as a third party beneficiary with respect to Section 8.04) and (b) such Transferred
Ownership Interests shall not be deemed held by the record holder thereof (and such Ownership
Interests shall not be taken into account) for purposes of determining the number of votes to which
such holder is entitled pursuant to the Second Amended and Restated Certificate of Incorporation or
By-laws; provided that such record holder shall continue to be entitled to share in all
profits and losses (including Net Profits and Net Losses), to receive such distribution or
distributions, and to receive such allocation of income, gain, loss, deduction or credit or similar
item to which the record holder of such Ownership Interests was entitled prior to such Transfer;
provided, further, that nothing in this Section 8.10 shall be deemed to limit any
rights that such record holder of Ownership Interests may have under the Second Amended and
Restated Certificate of Incorporation (other than Section 3(a) of the Second Amended and Restated
Certificate of Incorporation) or By-laws.

ARTICLE IX

DISSOLUTION, LIQUIDATION AND TERMINATION

          SECTION 9.01. No Dissolution. The Company shall not be dissolved by the admission of
additional Members in accordance with the terms of this Agreement.

          SECTION 9.02. Events Causing Dissolution. The Company shall be dissolved and its
affairs shall be wound up upon the occurrence of any of the following events (each, a
“Dissolution Event”):

     (a) the written consent of all Members;

     (b) the entry of a decree of judicial dissolution under Section 18-802 of the Act;

     (c) any event which makes it unlawful for the business of the Company to be carried on
by the Members;

     (d) any other event not inconsistent with any provision hereof causing a dissolution of
a limited liability company under the Act; or

     (e) the Bankruptcy of any Member; provided, however, that upon any such
event, the Company shall be deemed dissolved, but such dissolution shall not cause the
termination of the Company, it being understood and agreed that, upon any such dissolution,
the remaining Members may elect to continue to carry on the Company business pursuant to,
and subject to, all of the terms and provisions of this Agreement.

          SECTION 9.03. Distribution upon Dissolution. Upon dissolution, the Company shall
continue until the winding up of the affairs of the Company is completed. Upon the dissolution of
the Company, the Manager, or any other Person designated by the Manager (the “Liquidation
Agent”), shall take full account of the assets and liabilities of the Company and shall,
unless the Members agree otherwise, liquidate the assets of the Company as promptly as is
consistent with obtaining the fair value thereof. The proceeds of any liquidation shall be
applied and distributed in the following order:

     (a) First, to the payment of debts and liabilities of the Company (including payment of
all indebtedness to Members and/or their Affiliates, to the extent permitted by Law),
including the expenses of liquidation;

     (b) Second, to the establishment of any reserve which the Liquidation Agent shall deem
reasonably necessary for any contingent or unforeseen liabilities or obligations of the
Company (“Contingencies”). Such reserve may be paid over by the Liquidation Agent
to any attorney-at-law, or acceptable party, as escrow agent, to be held for disbursement in
payment of any Contingencies and, at the expiration of such period as shall be deemed
advisable by the Liquidation Agent for distribution of the balance in the manner hereinafter
provided in this Section 9.03; and

20

 

     (c) The balance, if any, to the holders of Ownership Interests, pro rata, in accordance
with their positive Capital Account balances (as determined after giving effect to all
allocations set forth in Article VI).

          SECTION 9.04. Time for Liquidation. A reasonable amount of time shall be allowed for the
orderly liquidation of the assets of the Company and the discharge of liabilities to creditors so
as to enable the Liquidation Agent to minimize the losses attendant upon such liquidation.

          SECTION 9.05. Termination. The Company shall terminate when all of the assets of the
Company, after payment of or due provision for all debts, liabilities and obligations of the
Company, shall have been distributed to the holders of Ownership Interests in the manner provided
for in this Article IX, and the Certificate of Formation shall have been cancelled in the manner
required by the Act.

          SECTION 9.06. Claims of the Members. The Members shall look solely to the Company’s
assets for the return of their Capital Contributions, and if the assets of the Company remaining
after payment of or due provision for all debts, liabilities and obligations of the Company are
insufficient to return such Capital Contributions, the Members shall have no recourse against the
Company or any other Member or any other Person. No Member with a negative balance in such
Member’s Capital Account shall have any obligation to the Company or to the other Members or to any
creditor or other Person to restore such negative balance upon dissolution or termination of the
Company or otherwise.

ARTICLE X

LIABILITY AND INDEMNIFICATION

          SECTION 10.01. Liability of Members. Except as otherwise provided under the Act, the
debts, obligations and liabilities of the Company, whether arising in contract, tort or otherwise,
shall be solely the debts, obligations and liabilities of the Company and neither any Member nor
the Manager shall be obligated or liable for any such debt, obligation or liability of the Company.
Except as otherwise provided by the laws of the State of Delaware, the debts, obligations and
liabilities of any Member, whether arising in contract, tort or otherwise, shall be solely the
debts, obligations and liability of such Member and neither any other Member, the Manager (in its
capacity as such) nor the Company shall be obligated or liable for any such debt, obligation or
liability of such Member.

          SECTION 10.02. Indemnification by the Company. (a) The Company shall indemnify,
defend and hold harmless any Member, the Manager or other Person (and any of their respective
officers, directors, managers, employees and agents), who was or is a party or is threatened to be
made a party to any threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the right of the Company)
by reason of the fact that he, she or it is or was a Member, the Manager, or an officer, director,
manager, employee or agent of the Company, the Manager or any Member, or is or was serving at the
request of the Company as a director, officer, manager, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, from and against

21

 

expenses (including attorneys’ fees and expenses), judgments, fines and amounts paid in settlement actually
and reasonably incurred by such Person in connection with such claim, action, suit or proceeding if
such Person acted in good faith and in a manner such Person reasonably believed to be in, or not
opposed to, the best interests of the Company, and, with respect to any criminal sanction or
proceeding, had no reasonable cause to believe that his, her or its conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the
Person did not act in good faith and in a manner which he, she or it reasonably believed to be in,
or not opposed to, the best interests of the Company, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his, her or its conduct was unlawful.

          (b) Expenses incurred in defending a civil or criminal action, suit or proceeding shall be
paid by the Company in advance of the final disposition of such action, suit or proceeding upon
receipt of an undertaking by or on behalf of any Member, the Manager, or any officer, director,
manager, employee or agent of the Company, the Manager or any Member to repay such amount if it
shall be ultimately determined by a court of competent jurisdiction from which no further appeal
may be taken or the time for appeal has lapsed that such Person is not entitled to be indemnified
by the Company pursuant to the terms and conditions of this Section 10.02.

          (c) The Company shall maintain insurance on behalf of any Person who is or was a Member, the
Manager, or an officer, director, employee or agent of the Company, the Manager or any Member, or
is or was serving at the request of the Company as an officer, director, manager, employee or agent
of another corporation, partnership, joint venture, trust or other enterprise against any liability
asserted against and incurred by such Person in any such capacity, or arising out of such Person’s
status as such, whether or not the Company would have the power to indemnify such Person against
such liability under this Section 10.02.

          (d) The indemnification and advancement of expenses provided by, or granted pursuant to, this
Section 10.02 shall continue as to a Person who has ceased to be a Member, the Manager, or any
officer, director, manager, employee or agent of the Company, the Manager or any Member, and shall
inure to the benefit of the heirs, executors, administrators and other legal successors of such
Person.

          (e) The indemnification provided by this Section 10.02 shall not be deemed exclusive of any
other rights to indemnification to which those seeking indemnification may be entitled under any
agreement, determination of Members or otherwise.

          (f) Any indemnification hereunder shall be satisfied only out of the assets of the Company
(including insurance and any agreements pursuant to which the Company and indemnified Persons are
entitled to indemnification), and the Members shall not, in such capacity, be subject to personal
liability by reason of these indemnification provisions.

          (g) No Person shall be denied indemnification in whole or in part under this Section 10.02
because such Person had an interest in the transaction with respect to which the indemnification
applies if the transaction was otherwise permitted by the terms of this Agreement.
