hereof.

     9. NO COVENANT FOR EMPLOYMENT OR ADVANCES: Borrower understands and acknowledges that neither
this Agreement nor any other Loan Document modifies Borrower’s at-will status at the Lender and
does not constitute an employment agreement or a promise by the Lender to continue Borrower’s
employment. Either the Lender or Borrower may terminate such employment relationship at any time,
with or without cause.

     10. NOTICES: All notices and other communications required or permitted hereunder shall be in

and obligations of the Borrower and Lender under the Loan Documents shall be binding upon and shall
inure to the benefit of the Borrower and Lender and their respective personal representatives,
successors, heirs, and permitted assigns.

     12. INCOME TAX CONSEQUENCES: Borrower hereby acknowledges that the Lender has made no
representation or warranty to Borrower concerning the income tax consequences of the loan to
Borrower and Borrower shall be solely responsible for ascertaining and bearing such tax
consequences.

     13. GOVERNING LAW: This Agreement shall be governed in all respects by the laws of the State
of California.

     14. HEADINGS: The titles and headings of the various paragraphs hereof are intended for means
of reference and are not intended to place any construction on the provisions hereof.

FORM OF SECURED PROMISSORY NOTE

 

 

SECURED PROMISSORY NOTE

			
	January 20, 2004
	 	$250,000.00

South San Francisco, California

     1. FOR VALUE RECEIVED, the undersigned, Gajus V. Worthington (“Borrower”), promises to
pay to the order of Fluidigm Corporation, a California corporation (“Lender”), at 7100
Shoreline Court, South San Francisco, California 94080 (or at such other place as Lender may from
time to time designate by written notice to Borrower), in lawful money of the United States, the
principal sum of Two Hundred Fifty Thousand Dollars ($250,000.00) (the “Principal”),
together with interest from the date of this Secured Promissory Note (“Note”) on the unpaid
principal balance at a rate equal to 3.52% per annum.

     This is a limited recourse Note. The sole recourse of the holder of this Note in the event of
the failure to pay this Note as and when due shall be limited to the “Pledged Collateral” as such
term is defined in the Stock Pledge Agreement of even date herewith (the “ Stock Pledge
Agreement”).

     2. PAYMENT: The Principal and interest due pursuant to this Note shall be paid as follows:

          2.1 Upon the occurrence of a Maturity Event (as defined herein), Borrower shall pay to Lender
all amounts due under this Note.

          2.2 Subject to the provisions of Section 4 herein, the Principal amount of this Note and all
accrued interest shall be due and payable on January 20, 2011 or earlier as follows:

               (a) In the event that Borrower voluntarily terminates his employment with Lender without “good
reason,” the Principal and all accrued interest shall be due and payable within thirty (30) days of
such termination date. In the event that Borrower voluntarily terminates his employment with “good
reason,” the Principal and all accrued interest shall be due and payable within thirty (30) days of
such termination date; provided, however, that if Borrower executes a waiver of all
claims against Lender in a form reasonably satisfactory to Lender, the Principal and accrued
interest shall be due and payable on the date which is 12 months following the termination date.
As used herein, “good reason” shall mean the occurrence of any of the following events without the
Borrower’s written consent:

                    (i) a substantial diminution in the nature, status or prestige of Borrower’s responsibilities,
title or reporting level or the addition of responsibilities of a nature, status or prestige
inconsistent with the office of Chief Executive Officer and President of a company such as Lender;

                    (ii) the relocation of Lender’s executive offices or principal business location to a point
more than one hundred (100) miles from the South San Francisco, California area;

A-1

 

 

                    (iii) a material reduction by Lender of Borrower’s annual salary or annual bonus as in effect
on the date hereof or as the same may be increased from time to time (other than a general
reduction applicable to all or substantially all officers of Lender); or

                    (iv) any action by Lender (including the elimination of benefit plans without providing
substitutes thereof or the reduction of Borrower’s benefits thereunder) that would substantially
diminish the aggregate value of Borrower’s fringe benefits as they exist at such time (other than
an elimination in benefits that applies to all or substantially all officers of the Lender).

               (b) In the event that Lender terminates Borrower’s employment with Lender for “cause,” the
Principal and all accrued interest shall be due and payable within thirty (30) days of such
termination date. In the event that Lender terminates Borrower’s employment with Lender other than
for “cause,” the Principal and all accrued interest shall be due and payable within thirty (30)
days of such termination date; provided, however, that if Borrower executes a
waiver of all claims against Lender in a form reasonably satisfactory to Lender, the Principal and
all accrued interest shall be due and payable on the date which is 12 months following the
termination date. As used herein, “cause” shall mean the occurrence of any of the following
events:

                    (i) Borrower’s repeated failure to satisfactorily perform his employment duties after written
notice by the Board of Directors of Lender (the “Board”) of such deficiency and an
opportunity to cure within a reasonable period;

                    (ii) Borrower has committed an act that is, in the opinion of the Board, intended to or does
materially injure the business of Lender;

                    (iii) Borrower has refused or failed to follow lawful and reasonable directions of the Board,
after written notice by the Board and a reasonable period thereafter to cure such performance;

                    (iv) Borrower has been convicted of a felony involving moral turpitude that is likely, in the
opinion of the Board, to inflict or has inflicted material injury on the business of Lender;

                    (v) a determination by the Board that Borrower has engaged in conduct constituting sexual
harassment of any current or former employee of Lender; or

                    (vi) a determination by the Board that Borrower is, or has been, engaging or in any manner
participating in any activity which is directly competitive with, or intentionally injurious to,
Lender.

               (c) In the event the Board has determined, upon advice of counsel, that repayment is required
to comply with “Applicable Law” (as defined herein), the Principal and all accrued interest
shall be due and payable immediately upon such determination by the Board. As used herein,
“Applicable Law” means any and all laws of whatever jurisdiction, within or without the
United States, including, but not limited to, the Sarbanes-Oxley Act of 2002, and the rules of any
stock exchange or quotation system on which Lender’s securities are then listed or quoted or

A-2

 

 

proposed to be listed or quoted, applicable to the taking or refraining from taking of any
action under this Note.

               (d) Without limiting the provisions of subsection (c) above, in the event that Lender (or any
successor or assign) files a registration statement under the Securities Act of 1933, as amended (a
“Registration”), or otherwise becomes an “Issuer” as such term is defined in the
Sarbanes-Oxley Act of 2002, the Principal and all accrued interest shall be due and payable on the
earliest of (i) the date immediately prior to date of filing of the registration statement with the
Securities and Exchange Commission relating to the Registration or (ii) the date immediately prior
to the date Lender otherwise becomes an “Issuer” within the meaning of the Sarbanes-Oxley Act of
2002; provided, however, in the event of any amendment to, or binding,
non-appealable judicial interpretation of, Applicable Law that would permit Lender to maintain the
indebtedness evidenced by the Loan after a Registration or such time as Lender becomes an “Issuer”,
the Board may, in its sole and absolute discretion and with the advice of legal counsel, extend
such due and payable date to a date not more than three years after the closing date of any initial
public offering of the Lender’s securities pursuant to a Registration.

               (e) In the event of a “Fundamental Corporate Transaction”, the Principal and all accrued
interest shall be due and payable on the date which is 12 months following the effective date of
the Fundamental Corporate Transaction. As used herein, a “Fundamental Corporate
Transaction” shall mean:

                    (i) a merger or consolidation in which Lender is not the surviving corporation (other than a
merger or consolidation with a wholly-owned subsidiary, a reincorporation of Lender in a different
jurisdiction, or other transaction in which there is no substantial change in the stockholders of
Lender or their relative stock holdings);

                    (ii) a merger in which Lender is the surviving corporation but after which the shareholders of
Lender immediately prior to such merger (other than any shareholder that merges, or which owns or
controls another corporation that merges, with Lender in such merger) cease to own their shares or
other equity interest in Lender;

                    (iii) the sale of all or substantially all of the assets of Lender; or

                    (iv) the acquisition, sale, or transfer of more than 50% of the outstanding shares of Lender
by tender offer or similar transaction.

          2.3 Principal and interest shall be payable in lawful money of the United States. Interest
shall be calculated on the basis of a 360-day year consisting of twelve (12) months, each of thirty
(30) days, and shall compound annually. Each payment shall be applied first to accrued interest,
then to any other amounts (other than Principal) payable hereunder as designated by Lender, and
then to reduce Principal.

          2.4 All payments made hereunder shall be made by Borrower free and clear of, and without
deduction for, any and all present and future taxes, levies, charges, deductions and

A-3

 

 

withholdings. Borrower shall pay upon demand any stamp or other taxes, levies or charges of
any jurisdiction with respect to the execution, delivery, performance and enforcement of this Note.

     3. SECURITY: This Note is secured by a pledge of shares of Common Stock of the Lender and
other collateral (collectively, the “Shares”) as set forth in the Stock Pledge Agreement.

     4. MATURITY EVENT: Upon the occurrence of a Maturity Event (as hereinafter defined), the
entire unpaid Principal balance and all accrued interest shall become immediately due and payable
without further demand or notice to Borrower. To the extent permitted by law, any of the following
events shall be a “Maturity Event” under this Note and the Stock Pledge Agreement:

               (a) Borrower shall fail to pay any amount of the Principal on this Note and all accrued
interest when due and shall fail to cure such non-payment within ten (10) days following written
notice of such delinquency.

               (b) There shall occur a breach or default in the performance of any obligation of Borrower
contained in this Note, the Stock Pledge Agreement, the Employee Loan Agreement executed
concurrently herewith (collectively, the “Loan Documents”), or any other agreement now or
hereafter entered into by Borrower, on the one hand, and the Lender, on the other hand, relating to
the loan evidenced by this Note.

               (c) Borrower shall sell, convey, encumber, grant any lien upon, or otherwise alienate the
Shares or the Property, or any part thereof, or any interest therein, or shall be divested of his
title or any interest therein in any manner or way, whether voluntarily or involuntarily, without
the written consent of the Lender being first had and obtained.

               (d) Borrower (i) admits in writing his inability to pay debts, (ii) makes an assignment for
the benefit of creditors, (iii) files a voluntary petition in bankruptcy, effects a plan or other
arrangement with creditors, liquidates his assets under arrangement with creditors, or liquidates
his assets under court supervision, (iv) has an involuntary petition in bankruptcy filed against
him that is not discharged within sixty (60) days after such petition is filed, or (v) applies for
or permits the appointment of a receiver or trustee or custodian for any of Borrower’s property or
assets which shall not have been discharged within sixty (60) days after the date of appointment.

               (e) The Principal and accrued interest shall have become due and payable, upon the happening
of certain events, on such dates as are set forth in Section 2.2 herein.

               (f) Any representation or warranty of Borrower contained herein or in any certificate or
agreement entered into between Borrower for the benefit of Lender in connection herewith shall
prove to be false or misleading in any material respect.

               (g) Any lien or other encumbrance is imposed against the Shares; provided,
however, that in the event that a lien or encumbrance is imposed against the Shares without
the consent of Borrower, a Maturity Event shall not occur until the lien or other monetary
encumbrance is imposed against the Shares for a period of at least thirty (30) days.

               (h) One (1) year following the death of the Borrower.

A-4

 

 

               (i) The occurrence of any event which causes the Loan and transactions contemplated under the
Loan Documents to be prohibited under Applicable Law, including any prohibition of the
Sarbanes-Oxley Act of 2002 or other prohibition relating to loans to officers of public companies
under federal or state law.

     5. LATE CHARGE: There shall be no late charge apart from the acceleration of Principal and the
accrual of interest.

     6. BORROWER’S REPRESENTATIONS: Borrower hereby makes the following representations and
warranties to the Lender and acknowledges that Lender is relying on such representations in making
the Loan:

          6.1 Borrower has and shall have good and marketable title to the Shares free and clear of any
security interests, liens or encumbrances other than (i) joint ownership of the Shares with
Borrower’s spouse; (ii) a right of first refusal and repurchase rights in favor of the Lender
entered into in connection with the purchase of the Shares; and (iii) the Stock Pledge Agreement in
favor of Lender securing this Note. The Shares are and shall be fully vested.

          6.2 Other than the consent of Borrower’s spouse, the consent of no other person or entity is
required to grant to Lender the security interest in the Shares evidenced by the Stock Pledge
Agreement.

          6.3 There are no actions, proceedings, claims, or disputes pending or, to the Borrower’s
knowledge, threatened against or affecting Borrower or the Shares.

     7. BORROWERS’ ADDITIONAL OBLIGATIONS: Borrower shall take any and all further actions that may
from time to time be required to ensure that the Stock Pledge Agreement creates a valid first
priority security interest on the Shares in favor of the Lender as security for the Note. Borrower
shall not further encumber the Shares or permit any lien or other security interest to encumber the
Shares. Upon request by Lender, but not more frequently than once during any calendar year,
Borrower shall furnish evidence reasonably satisfactory to the Lender that: (i) Borrower has good
and marketable title to the Shares; (ii) the consent of no other person or entity is required to
grant a first priority security interest in the Shares to the Lender; (iii) the Stock Pledge
Agreement is a first priority security interest in the Shares, and (iv) there are no other security
interests, liens or encumbrances against the Shares. If it should be hereafter determined that
there are defects against title or matters which could result in defects against title to the
Shares, or that the consent of another person or entity is required to grant to and perfect in the
Lender a valid first priority security interest on the Shares, Borrower shall promptly take all
action necessary to remove such defects and to obtain such consent and grant (or cause to be
granted) and perfect such security interest on the Shares. Failure of the Stock Pledge Agreement
to be a valid first priority security interest on the Shares shall be deemed a Maturity Event as
aforesaid.

     8. ATTORNEYS’ FEES: In the event of Borrower’s default hereunder, Borrower shall pay all costs
of collection, including reasonable attorneys’ fees incurred by the holder hereof on account of
such collection, whether or not suit is filed hereon.

A-5

 

 

     9. WAIVER: The waiver by Lender of any breach of or default under any term, covenant or
condition contained herein or in any other agreement referred to above shall be in writing and
shall not be deemed to be a waiver of any subsequent breach of or default under the same or any
other such term, covenant or condition.

     10. NO USURY: Borrower hereby represents and warrants that at no time shall the proceeds of
the indebtedness evidenced hereby be used “primarily for personal, family, or household purposes”
as that term is defined and used in Article XV of the California Constitution (as amended from time
to time). Anything in this Note to the contrary notwithstanding, it is expressly stipulated and
agreed that the intent of Borrower and Lender are to comply at all times with all usury and other
laws relating to this Note. If the laws of the State of California would now or hereafter render
usurious, or are revised, repealed or judicially interpreted so as to render usurious, any amount
called for under this Note, or contracted for, charged or received with respect to the loan
evidenced by this Note, or if any prepayment by Borrower results in Borrower having paid any
interest in excess of that permitted by law, then it is Borrower’s and Lender’s express intent that
all excess amounts theretofore collected by Lender be credited to the principal balance of this
Note (or, if this Note has been paid in full, refunded to Borrower), and the provisions of this
Note immediately be deemed reformed and the amounts therefor collectible hereunder reduced, without
the necessity of execution of any new document, so as to comply with the then applicable law, but
so as to permit the recovery of the fullest amount otherwise called for hereunder.

     11. PREPAYMENT: Borrower may prepay all or any portion of this Note at any time prior to the
time it is due, with no premium or penalty.

     12. GENERAL PROVISIONS: This Note shall be governed by and construed in accordance with the
laws of the State of California. The makers of this Note hereby waive presentment for payment,
protest and demand, notice of protest, demand and dishonor and nonpayment of this Note, and consent
that Lender may extend the time for payment or otherwise modify the terms of payment or any part of
the whole of the debt evidenced by this Note, at the request of any person liable hereon, and such
consent shall not alter nor diminish the liability of any person. Borrower hereby waives the
defense of the statute of limitations in any action on this Note to the extent permitted by law.
Time is of the essence of this Note, the Loan Documents and any other document executed by Borrower
in connection therewith. Liability hereunder shall be joint and several among Borrower and all
other persons and entities now or hereafter liable for all or any part of the Loan.

     13. ACKNOWLEDGEMENT BY BORROWER: THIS NOTE, THE LOAN AGREEMENT, THE STOCK PLEDGE AGREEMENT,
AND ALL RELATED DOCUMENTATION ARE EXECUTED VOLUNTARILY AND WITHOUT ANY DURESS OR UNDUE INFLUENCE ON
THE PART OF OR ON BEHALF OF THE BORROWER, WITH THE FULL INTENT OF CREATING THE OBLIGATIONS AND
SECURITY INTERESTS DESCRIBED HEREIN AND THEREIN. BORROWER ACKNOWLEDGES THAT: (a) BORROWER HAS READ
SUCH DOCUMENTATION; (b) BORROWER HAS BEEN REPRESENTED IN THE PREPARATION, NEGOTIATION AND EXECUTION
OF SUCH DOCUMENTATION BY LEGAL COUNSEL OF BORROWER’S OWN CHOICE (OR HAS KNOWINGLY AND VOLUNTARILY
CHOSEN NOT TO SEEK SUCH REPRESENTATION);

A-6

 

 

(c) BORROWER UNDERSTANDS THE TERMS AND CONSEQUENCES OF THIS NOTE, THE EMPLOYEE LOAN AGREEMENT,
THE STOCK PLEDGE AGREEMENT, AND ALL RELATED AGREEMENTS AND DOCUMENTATION AND THE OBLIGATIONS THEY
CREATE; AND (d) BORROWER IS FULLY AWARE OF THE LEGAL AND BINDING EFFECT OF THIS NOTE, THE EMPLOYEE
LOAN AGREEMENT, THE STOCK PLEDGE AGREEMENT AND THE OTHER DOCUMENTS CONTEMPLATED BY OR ENTERED INTO
IN CONNECTION WITH THIS NOTE.

     This STOCK PLEDGE AGREEMENT, dated as of January 20, 2004 (this “Pledge Agreement”),

California corporation (“Secured Party”).

RECITALS

Agreement”), and Debtor has executed a Secured Promissory Note dated as of the date hereof (the
“Note”), in favor of the Secured Party in the principal amount of $250,000.00.

     B. In order to induce the Secured Party to extend the credit evidenced by the Note, Debtor has
agreed to enter into this Pledge Agreement and to pledge and grant to Secured Party the security
interest in the Pledged Collateral described below.

PLEDGE AGREEMENT

     NOW, THEREFORE, in consideration of the above recitals and for other good and valuable
consideration, the receipt and adequacy of which are hereby acknowledged, Debtor hereby agrees with
Secured Party as follows:

     1. Definitions and Interpretation. Unless otherwise defined herein, all other
capitalized terms used herein and defined in the Note shall have the respective meanings given to
those terms in the Note, and all terms defined in the California Uniform Commercial Code (the
“UCC”) shall have the respective meanings given to those terms in the UCC.

     2. The Pledge. To secure the Obligations as defined in Section 3 hereof, Debtor
hereby pledges to Secured Party, and grants to Secured Party a security interest in, all of
Debtor’s right, title and interest, whether now existing or hereafter arising in all instruments,
certificated and uncertificated securities, money and general intangibles of, relating to or
arising from the following property (the “Pledged Collateral”):

     (a) The shares of stock of the Company more particularly described on Schedule A
attached hereto (the “Pledged Shares”);

     (b) All dividends (including cash dividends), other distributions (including stock redemption
proceeds), or other property, securities or instruments in respect of or in exchange for the
Pledged Shares, whether by way of dividends, stock dividends, recapitalizations, mergers,
consolidations, split-ups, combinations or exchanges of shares or otherwise; and

     (c) All proceeds of the foregoing (“Proceeds”).

     3. Security for Obligations. The obligations secured by this Pledge Agreement (the
“Obligations”) shall mean and include all loans, advances, debts, liabilities and
obligations, howsoever arising, owed by Debtor to the Secured Party of every kind and description
(whether or

B-1

 

 

not evidenced by any note or instrument and whether or not for the payment of money), now
existing or hereafter arising under or pursuant to the terms of the Note, including, all interest,
fees, charges, expenses, attorneys’ fees and costs and accountants’ fees and costs chargeable to
and payable by Debtor hereunder and thereunder and under the Loan Agreement, in each case, whether
direct or indirect, absolute or contingent, due or to become due, and whether or not arising after
the commencement of a proceeding under Title 11 of the United States Code (11 U.S.C. Section 101
et seq.), as amended from time to time (including post-petition interest) and
whether or not allowed or allowable as a claim in any such proceeding.

     4. Delivery of Pledged Collateral. All certificates or instruments representing or
evidencing the Pledged Collateral shall be delivered to Secured Party and shall be in suitable form
for transfer by delivery, or shall be accompanied by duly executed instruments of transfer or
assignment in blank, all in form and substance satisfactory to Secured Party.

     5. Representations and Covenants. Debtor hereby represents and warrants as follows:

          (a) Issuance of Pledged Shares, Etc. The Pledged Shares have been duly authorized and
are validly issued and are fully paid and non-assessable, and the Pledged Shares are owned by
Debtor free and clear of any and all liens, pledges, encumbrances or charges (other than the lien
created in favor of Secured Party by this Pledge Agreement and a right of first refusal and certain
repurchase rights granted to the Secured Party in connection with Debtor’s purchase of the Shares),
and Debtor has not optioned or otherwise agreed to sell, hypothecate, pledge, or otherwise encumber
or dispose of the Pledged Shares. The Pledged Shares are fully vested.

          (b) Security Interest. The pledge of the Pledged Collateral creates a valid security
interest in the Pledged Collateral, which security interest is a perfected and first priority
security interest, securing the payment of the Obligations and the obligations hereunder.

          (c) Restatement of Representations and Warranties. On and as of the date any property
becomes Pledged Collateral, the foregoing representations and warranties shall apply to such
additional Pledged Collateral.

     6. Further Assurances.

          (a) Further Instruments and Documents; Action. Debtor agrees that at any time and from
time to time, at Debtor’s expense, Debtor will promptly execute and deliver all further instruments
and documents, including without limitation all additional Pledged Collateral, and take all further
action, that may be necessary or desirable, or that Secured Party may reasonably request, in order
to perfect and protect any security interest granted or purported to be granted hereby or to enable
Secured Party to exercise and enforce its rights and remedies hereunder with respect to any Pledged
Collateral.

          (b) Margin Regulations. In the event that Secured Party’s Common Stock is now or
later classified as “margin stock” as such term is defined under Regulation U of the Board of
Governors of the Federal Reserve System (“Regulation U”) and Secured Party is classified as
a “lender” within the meaning of Regulation U, Debtor agrees to cooperate with Secured Party in

B-2

 

 

making any amendments to the Note (and related agreements) or providing any additional
collateral as may be necessary to comply with such regulations.

          (c) Liens on Pledged Collateral. Debtor agrees not to create, incur, assume or suffer
to exist any lien or security interest of any kind upon the Pledged Collateral.

     7. Voting Rights; Dividends; Etc.

          (a) Rights Prior to an Event of Default. So long as no Event of Default shall have
occurred and be continuing:

               (i) Debtor shall be entitled to exercise any and all voting and other consensual rights
pertaining to the Pledged Collateral (including the Pledged Shares) or any part thereof for any
purpose not inconsistent with the terms of this Pledge Agreement.

     (ii) Debtor shall be entitled to receive and retain free and clear of the security interest of
Secured Party hereunder any and all dividends and interest paid in respect of the Pledged Shares,
provided, however, that any and all (A) dividends and interest paid or payable
other than in cash in respect of, and instruments and other property received, receivable or
otherwise distributed in respect of, or in exchange for any Pledged Shares, (B) dividends and other
distributions paid or payable in cash in respect of any Pledged Shares in connection with a partial
or total liquidation or dissolution or in connection with a reduction of capital, capital surplus
or paid-in-surplus, and (C) cash paid, payable or otherwise distributed in respect of principal of,
or in redemption of, or in exchange for, any Pledged Shares, shall be, and shall be forthwith
delivered to Secured Party to hold as, Pledged Collateral and shall, if received by Debtor, be
received in trust for the benefit of Secured Party, be segregated from the other property or funds
of Debtor and be forthwith delivered to Secured Party as Pledged Collateral in the same form as so
received (with any necessary endorsement) to be held as part of the Pledged Collateral.

          (b) Rights Following an Event of Default. Upon the occurrence and during the
continuance of an Event of Default:

               (i) All rights of Debtor to exercise the voting and other consensual rights which it would
otherwise be entitled to exercise pursuant to Section 7(a)(i) and to receive the dividends and
interest payments which it would otherwise be authorized to receive and retain pursuant to Section
7(a)(ii) shall cease and all such rights shall thereupon become vested in Secured Party which shall
thereupon have the sole right, but not the obligation, to exercise such voting and other consensual
rights and to receive and hold as Pledged Collateral such dividends and interest payments.

               (ii) All dividends and interest payments which are received by Debtor contrary to the
provisions of subparagraph (i) of this Section 7(b) shall be received in trust for the benefit of
Secured Party, shall be segregated from other funds of Debtor and shall be forthwith delivered to
Secured Party as Pledged Collateral in the same form as so received (with any necessary
endorsement).

B-3

 

 

     8. Events of Default.

          (a) Event of Default. An “Event of Default” shall mean the occurrence of one
or more of the following described events:

               (i) Debtor shall default in the payment of principal or interest on the Note when the same is
due, or default in the payment of any expense or other amount payable under the Loan Agreement, the
Note or under this Pledge Agreement; or

               (ii) Debtor shall breach the provisions of Section 6(c) of this Pledge Agreement; or

               (iii) Debtor shall default in the performance of, or there shall be a breach of, any term,
provision, representation, warranty, covenant, agreement or obligation (other than a covenant,
agreement or obligation referred to in Section 8(a)(i) or Section 8(a)(ii) of this Pledge
Agreement) contained in the Loan Agreement, Note or this Pledge Agreement and Debtor shall fail to
cure such default within ten (10) days after written notice thereof from Secured Party.

          (b) Rights Under the UCC. In addition to all other rights granted hereby, by the
Note, by the Loan Agreement and by law, Secured Party shall have, with respect to the Pledged
Collateral, the rights and obligations of a secured party under the UCC.

          (c) Sale of Pledged Collateral. Debtor acknowledges and recognizes that Secured Party
may be unable to effect a public sale of all or a part of the Pledged Collateral (including the
Pledged Shares) and may be compelled to resort to one or more private sales to a restricted group
of purchasers who will be obligated to agree, among other things, to acquire the Pledged Collateral
for their own account, for investment and not with a view to the distribution or resale thereof.
Debtor acknowledges that any such private sales may be at prices and on terms less favorable to
Secured Party than those of public sales, and agrees that so long as such sales are made in good
faith such private sales shall be deemed to have been made in a commercially reasonable manner and
that Secured Party has no obligation to delay sale of any Pledged Collateral to permit the issuer
thereof to register it for public sale under the Securities Act of 1933, as amended or under any
state securities law.

          (d) Notice, Etc. In any case where notice of sale is required, ten (10) days’ notice
shall be deemed reasonable notice. Secured Party may have resort to the Pledged Collateral or any
portion thereof with no requirement on the part of Secured Party to proceed first against any other
person, entity or property.

          (e) Other Remedies. Upon the occurrence and during the continuance of an Event of
Default, (i) at the request of Secured Party, Debtor shall assemble and make available to Secured
Party all records relating to the Pledged Collateral at any place or places specified by Secured
Party, together with such other information as Secured Party shall request concerning Debtor’s
ownership of the Pledged Collateral and relationship to the Company; and (ii) Secured Party or its
nominee shall have the right, but shall not be obligated, to vote or give consent with respect to
the Pledged Collateral (including the Pledged Shares) or any part thereof.

B-4

 

 

     9. Secured Party Appointed Attorney-in-Fact.

     Debtor hereby appoints Secured Party as Debtor’s attorney-in-fact, with full authority in the
place and stead of Debtor and in the name of Debtor or otherwise, from time to time in Secured
Party’s discretion and to the full extent permitted by law to take any action and to execute any
instrument which Secured Party may deem reasonably necessary or advisable to accomplish the
purposes of this Pledge Agreement in accordance with the terms and provisions hereof, including
without limitation, to receive, endorse and collect all instruments made payable to Debtor
representing any dividend, interest payment or other distribution in respect of the Pledged
Collateral or any part thereof and to give full discharge for the same.

     Debtor hereby ratifies all reasonable actions that said attorney shall lawfully do or cause to
be done by virtue hereof. This power of attorney is a power coupled with an interest and shall be
irrevocable. The powers conferred on Secured Party hereunder are solely to protect its interests
in the Pledged Collateral and shall not impose any duty upon Secured Party to exercise any such
powers. Secured Party shall be accountable only for amounts that it actually receives as a result
of the exercise of such powers and in no event shall Secured Party or any of its officers,
directors, employees or agents be responsible to Debtor for any act or failure to act, except for
gross negligence or willful misconduct.

     10. Release of Pledged Collateral.

     Subject to any applicable law, rule or regulation to the contrary, upon written request of
Debtor no more than once per calendar quarter, Secured Party shall deliver to Debtor a certificate
or certificates representing so many full Pledged Shares (or other securities issued in respect
thereof) the fair market value of which, as determined by the Board of Directors of the Company in
its sole discretion, is greater than the principal amount and interest due under the Note as of the
date of such delivery. Upon delivery of the certificate or certificates by Secured Party, such
Pledged Shares (or other securities in respect thereof) shall no longer constitute Pledged
Collateral.

     11. Miscellaneous.

          (a) Notices. All notices and other communications required or permitted hereunder
shall be in writing and may be given by (a) personal delivery, (b) certified mail, postage prepaid,
return-receipt requested, (c) courier service, fully prepaid for next business day delivery, or (d)
facsimile. Any such notice shall be properly addressed to the address of the parties set forth on
the signature page hereof and shall be deemed to have been given (i) if personally delivered, when
delivered, (ii) if by certified mail, return-receipt requested, when delivered or refused, (iii) if
by courier service, on the next business day following deposit, cost prepaid, with Federal Express
or similar private carrier, or (iv) if by facsimile, instantaneously upon confirmation of receipt
of facsimile. The Secured Party or Debtor may change their respective addresses by giving notice of
the same in accordance with this paragraph. The term “business day” shall mean a day on which
national banks are open for business in San Francisco, California.

B-5

 

 

          (b) Nonwaiver. No failure or delay on Secured Party’s part in exercising any right
hereunder shall operate as a waiver thereof or of any other right nor shall any single or partial
exercise of any such right preclude any other further exercise thereof or of any other right.

          (c) Amendments and Waivers. This Pledge Agreement may not be amended or modified, nor
may any of its terms be waived, except by written instruments signed by Debtor and Secured Party.
Each waiver or consent under any provision hereof shall be effective only in the specific instances
for the purpose for which given.

          (d) Assignments. Debtor may not assign any of his rights and/or duties under this
Agreement without the prior written consent of the Secured Party, which consent may be withheld in
the sole discretion of Lender. All of the rights and/or duties of the Secured Party under this
Agreement, shall be freely assignable. Subject to the foregoing, the rights and obligations of the
Debtor and Secured Party under this Agreement shall be binding upon and shall inure to the benefit
of the Debtor and Secured Party and their respective personal representatives, successors, heirs,
and permitted assigns. 

          (e) Cumulative Rights, etc. The rights, powers and remedies of Secured Party under
this Pledge Agreement shall be in addition to all rights, powers and remedies given to Secured
Party by virtue of any applicable law, rule or regulation of any governmental authority, the Note
or any other agreement, all of which rights, powers, and remedies shall be cumulative and may be
exercised successively or concurrently without impairing Secured Party’s rights hereunder. Debtor
waives any right to require Secured Party to proceed against any person or entity or to exhaust any
Pledged Collateral or to pursue any remedy in Secured Party’s power.

          (f) Partial Invalidity. If any time any provision of this Pledge Agreement is or
becomes illegal, invalid or unenforceable in any respect under the law or any jurisdiction, neither
the legality, validity or enforceability of the remaining provisions of this Pledge Agreement nor
the legality, validity or enforceability of such provision under the law of any other jurisdiction
shall in any way be affected or impaired thereby.

          (g) Expenses. Each of Debtor and Secured Party shall bear its own costs in connection
with the preparation, execution and delivery of, and the exercise of its duties under, this Pledge
Agreement.

          (h) Governing Law. This Pledge Agreement shall be governed by and construed in
accordance with the laws of the State of California without reference to conflicts of law rules
(except to the extent governed by the UCC).

          Section 3.9 Employee Benefits.

          (a) As of the date hereof, each material benefit or compensation plan, fund, program,
agreement, scheme, contract, policy or arrangement (each, an “Employee Benefit Plan”) of
the Company and its Subsidiaries providing for employee benefits or for the remuneration, direct or
indirect, of the current or former employees, managers or officers of any of the Company and its
Subsidiaries (the “Employees”) or of the current or former directors, consultants,
independent contractors, contingent workers or leased employees of the Company and its
Subsidiaries, or the dependents of any of them, or with respect to which the Company or any of its
Subsidiaries has or reasonably could have any liability, including, but not limited to, each
“employee benefit plan” within the meaning of Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended (“ERISA”) (determined without regard to whether such plan
is subject to ERISA), each material deferred compensation, retirement, severance, stock option,
stock purchase, stock appreciation rights, stock based, incentive or bonus plan or agreement, each
material health, vacation, summer hours, supplemental unemployment benefit, hospitalization
insurance, medical, dental, legal and each other material employee benefit plan, fund, program
arrangement or scheme is referred to in this Agreement as a “Company Benefit Plan”. All
material Company Benefit Plans are listed on Section 3.9(a) of the Company Disclosure Letter.

          (b) As of the date hereof, except where a failure to comply would not result in a material
liability, all Company Benefit Plans, other than “multiemployer plans” within the meaning of
Section 3(37) of ERISA (each, a “Multiemployer Plan”) and non-United States Company Benefit
Plans (collectively, “Company U.S. Benefit Plans”) have been established, registered,
qualified, invested, operated and administered in all respects in compliance with ERISA, the Code
and other applicable Laws. Each Company U.S. Benefit Plan that is subject to ERISA (a “Company
ERISA Plan”) and that is an “employee pension benefit plan” within the meaning of Section 3(2)
of ERISA intended to be qualified under Section 401(a) of the Code and the trust maintained
thereunder that is intended to be exempt from taxation under Section 501 of the Code has received a
favorable determination letter from the IRS or other letter indicating that it is so qualified, and
no circumstances exist that are likely to result in the loss of such exempt status which would not,
individually or in the aggregate, be reasonably expected to be material. Any voluntary employees’
beneficiary association within the meaning of Section 501(c)(9) of the Code which provides benefits
under a Company U.S. Benefit Plan has (i) received an opinion letter from the IRS recognizing its
exempt status under Section 501(c)(9) of the Code and (ii) filed a timely notice with the IRS
pursuant to Section 505(c) of the Code, and no circumstances exist that are likely to result in the
loss of such exempt status under Section 501(c)(9) of the Code which would not, individually or in
the aggregate, be reasonably expected to be material. Neither the Company nor its Subsidiaries has
incurred, and no fact exists that reasonably could be expected to result in any tax or penalty
imposed by Section 4975 of the Code or Section 502(i) of ERISA in an amount that would be material
to the Company and its Subsidiaries with respect to any Company Benefit Plan.

          (c) None of the Company, any of its Subsidiaries or any ERISA Affiliate has ever sponsored,
maintained, contributed to or has any liability with respect to an Employee Benefit Plan that is or
was subject to Title IV of ERISA or Section 412 of the Code, and neither the Company, any of its
Subsidiaries nor any ERISA Affiliate has ever sponsored, maintained,

-15-

 

contributed to or has any liability with respect to an Employee Benefit Plan within the past
six years that is or was a Multiemployer Plan or subject to Section 302 of ERISA. Except as would
not, individually or in the aggregate, be reasonably expected to be material, none of the Company,
any of its Subsidiaries or any ERISA Affiliate has incurred or could reasonably be likely to incur
any withdrawal liability (as defined in Part I of Subtitle E of Title IV of ERISA) with respect to
any Multiemployer Plan that has not been satisfied in full. Except as would not, individually or
in the aggregate, be reasonably expected to be material, none of the Company, any of its
Subsidiaries or any ERISA Affiliate has terminated or withdrawn from or sought a funding waiver
with respect to, and no fact exists that could reasonably be expected to result in a termination or
withdrawal from or seeking a funding waiver with respect to, an Employee Benefit Plan that is
subject to Title IV of ERISA that was sponsored, maintained or contributed to within the past five
years by the Company, any of its Subsidiaries or any ERISA Affiliate or with respect to which the
Company, any of its Subsidiaries or any ERISA Affiliate has any liability (each a “Pension
Plan”), which would, individually or in the aggregate, be reasonably expected to be material.
No material liability under Subtitle C or D of Title IV of ERISA has been or is reasonably expected
to be incurred by any of the Company or its Subsidiaries with respect to any Pension Plan. Except
as would not, individually or in the aggregate, be reasonably expected to be material, no notice of
a “reportable event”, within the meaning of Section 4043 of ERISA for which the reporting
requirement has not been waived or extended (other than pursuant to Pension Benefit Guaranty
Corporation (“PBGC”) Reg. Section 4043.33 or 4043.66) has been required to be filed for any
Pension Plan within the 12-month period ending on the date hereof or will be required to be filed
in connection with the transactions contemplated by this Agreement and no notices have been
required to be sent to participants and beneficiaries or the PBGC under Section 302 or 4011 of
ERISA or Section 412 of the Code. None of the Company, any of its Subsidiaries or any ERISA
Affiliates have filed a notice of intent to terminate any Pension Plan or have adopted any
amendment to treat a Pension Plan as terminated within the past six years, and to the Knowledge of
the Company, the PBGC has not instituted proceedings as of the date hereof to treat any Pension
Plan as terminated. To the Knowledge of the Company, the actuarial reports for each Pension Plan
fairly presents the financial condition and the results of operations of each such Pension Plan in
accordance with GAAP.

          (d) As of the date hereof, all material contributions or premiums required to be made or paid
under each Company Benefit Plan (including all Pension Plans) or by applicable Law, as of the date
hereof, have been timely made or paid in accordance with the terms of such plan or applicable Law,
and all obligations in respect of each such plan have been properly accrued and reflected in the
most recent consolidated balance sheet filed or incorporated by reference in the Company Reports
prior to the date hereof in accordance with GAAP. No Pension Plan has an “accumulated funding
deficiency” (whether or not waived) within the meaning of Section 412 of the Code or Section 302 of
ERISA, and, on and after the effectiveness of the Pension Protection Act of 2006, there has been no
failure by any Pension Plan to satisfy the minimum funding standards (within the meaning of Section
412 of the Code or Section 302 of ERISA) applicable to such Pension Plan, whether or not waived.
No Pension Plan has been required to file information pursuant to Section 4010 of ERISA for the
current or most recently completed plan year. It is not reasonably anticipated that required
minimum contributions to any Pension Plan under Section 412 of the Code will be materially
increased by application of Section 412(l) of the Code. Neither the Company, nor its Subsidiaries
nor any ERISA Affiliate has provided, or is required to provide, security to any Pension Plan.

-16-

 

          (e) As of the date hereof, under each Pension Plan which is a single-employer plan, as of the
last day of the most recent plan year ended prior to the date hereof, the actuarially determined
present value of all “benefit liabilities”, within the meaning of Section 4001(a)(16) of ERISA (as
determined on the basis of the actuarial assumptions contained in such Pension Plan’s most recent
actuarial valuation), did not exceed the then current value of the assets of such Pension Plan, and
there has been no material change and no material change is reasonably anticipated to occur in the
financial condition, whether or not as a result of a change in funding method, of such Pension Plan
since the last day of the most recent plan year.

          (f) As of the date hereof, none of the Company or its Subsidiaries has any obligations for
retiree health and life benefits under any Company ERISA Plan, any Employee Benefit Plan with
respect to which the Company or any of its Subsidiaries has any liability or any Collective
Bargaining Agreement. The Company and its Subsidiaries may amend or terminate any such plan at any
time without incurring any material liability thereunder other than in respect of claims incurred
prior to such amendment or termination.

          (g) As of the date hereof, neither the execution, delivery and performance of this Agreement
nor the consummation of the transactions contemplated hereby will (w) entitle any current or former
employee, director or officer of the Company or any of its Subsidiaries to severance pay or any
increase in severance pay or any other material payment upon any termination of employment after
the date hereof, (x) accelerate the time of payment or vesting or result in any payment or funding
(through a grantor trust or otherwise) of compensation or material benefits under, materially
increase the amount of compensation due any such individual, increase the amount payable or result
in any other material obligation pursuant to, any of the Company Benefit Plans, (y) limit or
restrict the right of the Company or its Subsidiaries or, after the consummation of the
transactions contemplated hereby, Buyer to merge, amend or terminate any of the Company Benefit
Plans or (z) result in payments that would not be deductible for federal income tax purposes under
Code Section 162(m) or by reason of Section 280G of the Code.

          (h) The Company has made available to Buyer, with respect to each material Company Benefit
Plan and material Pension Plan, correct and complete copies of: (i) each writing constituting a
part of such Company Benefit Plan and Pension Plan, including, without limitation, all plan
documents (including amendments), benefit schedules, trust agreements, and insurance contracts and
other funding vehicles; (ii) the most recent actuarial report; and (iii) the most recent annual
financial report, if any.

Representations and Warranties of Buyer

          Buyer represents and warrants to the Company as follows:

          Section 4.1 Organization and Authority of Buyer. Buyer is a legal entity duly
organized, validly existing and in good standing under the Laws of its jurisdiction of organization
and has all requisite corporate or similar power and authority to own, lease and operate its
properties and assets and to carry on its business as presently conducted and is qualified to do
business and is in good standing as a foreign corporation or other entity in each jurisdiction
where the ownership, leasing or operation of its assets or properties or conduct of its business
requires such qualification, except where the failure to be so organized, qualified or in good
standing, or to have such power or authority, are not, individually or in the aggregate, reasonably
likely to prevent or materially delay the consummation of the transactions contemplated hereby or
pursuant to the Ancillary Agreements. Buyer has made available to the Company complete and correct
copies of Buyer’s certificate of incorporation and by-laws or comparable governing documents, each
as amended to the date hereof, and each as so delivered is in full force and effect.

          Section 4.2 Corporate Authority. Buyer has all requisite corporate or other
organizational power and authority and has taken all corporate or other organizational action
necessary in order to execute, deliver and perform its obligations under this Agreement and the
Ancillary Agreements. This Agreement has been, and the Ancillary Agreements when executed will be,
duly executed and delivered by Buyer and constitutes or will constitute valid and binding
agreements of Buyer as a party hereto and thereto, enforceable against Buyer as a party hereto and
thereto in accordance with their respective terms, subject to the Bankruptcy and Equity Exception.

          Section 4.3 Consents and Approvals. (a) Other than the filings and/or notices
referred to in Section 3.3(a), no notices, reports or other filings are required to be made by
Buyer with, nor are any consents, registrations, approvals, permits or authorizations required to
be obtained by Buyer from, any Governmental Entity in connection with the execution and delivery of
this Agreement or the Ancillary Agreements by Buyer and the consummation by Buyer of the
transactions contemplated hereby or thereby, except those that the failure to make or obtain are
not, individually or in the aggregate, reasonably likely to prevent or materially delay the
consummation of the transactions contemplated hereby or pursuant to the Ancillary Agreements.

          (b) The execution, delivery and performance of this Agreement and each of the Ancillary
Agreements by Buyer does not, and the consummation of the transactions contemplated hereby and
thereby will not, constitute or result in (i) a breach or violation of, or a default under, the
certificates of organization, limited liability company agreements, certificates

-21-

 

of incorporation, bylaws or comparable governing documents of Buyer or any of its
Subsidiaries, (ii) with or without notice, lapse of time or both, a breach or violation of, a
termination (or right of termination) or a default under, the creation or acceleration of any
obligations or the creation of a Lien on any of the assets of Buyer or any of its Subsidiaries
pursuant to any Contract binding upon Buyer or any of its Subsidiaries or, assuming compliance with
the matters referred to in Section 4.3(a), under any Law to which Buyer or any of its Subsidiaries
is subject or (iii) any change in the rights or obligations of any party under any Contract binding
Buyer or any of its Subsidiaries, except, in the case of clause (ii) or (iii) above, for any such
breach, violation, termination, default, creation, acceleration or change that, individually or in
the aggregate, is not reasonably likely to prevent or materially delay the consummation of the
transactions contemplated hereby or pursuant to the Ancillary Agreements.

          Section 4.4 Brokers and Finders. Other than any fee payable by Buyer or its
Affiliates to Lehman Brothers Inc, as financial advisor, none of Buyer or any of its Affiliates has
employed any broker, finder, consultant or intermediary in connection with the transactions
contemplated by this Agreement or the Ancillary Agreements who would be entitled to a broker’s,
finder’s or similar fee or commission in connection herewith or therewith or upon the consummation
hereof or thereof, or if the Closing does not occur.

          Section 4.5 Certain Regulatory Matters. Each of Buyer and Minority Member Parent
is a newly formed special purpose vehicle formed solely for purpose of holding an investment
(directly or indirectly) in the Company. Minority Member Parent is an entity taxed as a
corporation for United States federal income tax purposes. As of the Closing Date, none of OAC or
any other investor that, after the date hereof and prior to the Closing, executes an equity
commitment letter in favor of Buyer or any of its Affiliates, will have any Direct or Indirect EFH
Interest (as defined in the Amended and Restated LLC Agreement). As of the date hereof, to the
Knowledge of Buyer and other than as disclosed to EFH on or prior to the date hereof, none of OAC,
GIC nor any of their respective Affiliates, has any direct or indirect equity ownership interest in
EFH (other than any indirect immaterial interest and other than in respect of any equity interest
in EFH held through investment funds affiliated with the Fund Advisors (as defined in the Amended
and Restated LLC Agreement)).

          Section 4.6 Financial Capability; Equity Commitment Letters; Indebtedness.

          (a) Buyer has delivered to the Company true and complete copies of the equity commitment
letters, dated as of the date hereof (collectively, the “Equity Commitment Letters”),
between Buyer and Cheyne and between Buyer and OAC, pursuant to which (i) subject only to the
conditions precedent in this Agreement, each of Cheyne and OAC has committed to invest the amount
set forth therein and (ii) the parties thereto have granted third party beneficiary rights under
each such letter to the Company. None of the Equity Commitment Letters have been amended or
modified (or any provisions thereunder waived), and the respective commitments contained therein
have not been withdrawn or rescinded in any respect. Each of the Equity Commitment Letters is in
full force and effect and is a legal, valid and binding obligation of the parties thereto. There
are no conditions precedent or other contingencies related to the funding of the full amount set
forth in the Equity Commitment Letters, other than the satisfaction or waiver of the conditions
precedent in Article VI. Buyer will have, immediately prior to the Closing, sufficient readily
available cash funds to pay the

-22-

 

Purchase Price upon the terms and conditions of this Agreement, to otherwise consummate the
transactions contemplated hereby or pursuant to the Ancillary Agreements and to perform its
obligations hereunder and thereunder after the Closing. Cheyne is an investment vehicle controlled
by GIC, was not formed for purposes of making an investment in the Company, and, as of the Closing
Date, will have material investments other than its indirect investment in the Company.

          (b) Neither Buyer nor Minority Member Parent will have outstanding at the Closing any
indebtedness for borrowed money issued to or borrowed from third parties (other than, for
certainty, any indebtedness owing to Cheyne, BPC Penco, or any other entity that directly holds
equity interests in Minority Member Parent, or any of their respective Affiliates).

          Section 4.7 Securities Act. Buyer is acquiring the Buyer Units solely for the purpose
of investment and not with a view to, or for sale in connection with, any distribution thereof in
violation of the Securities Act. Buyer acknowledges that the Buyer Units are not registered under
the Securities Act or any applicable state securities law, that the offering of the Buyer Units is
being made in reliance on one or more exemptions for private offerings under the Securities Act and
applicable state securities laws and that the Buyer Units may not be transferred, sold or otherwise
disposed of except pursuant to the registration provisions of the Securities Act or pursuant to an
applicable exemption therefrom and pursuant to state securities laws and regulations as applicable.

          Section 4.8 Litigation. As of the date hereof, there are no civil, criminal or
administrative claims, actions, suits, demands, proceedings or investigations pending or, to the
Knowledge of Buyer, threatened against Buyer or any of its Subsidiaries, at law, in equity or
otherwise, in, before or by, any court or Governmental Entity or authority which would be
reasonably likely to prevent or materially delay the ability of Buyer to consummate the
transactions contemplated hereby or pursuant to the Ancillary Agreements.

          Section 4.9 Investigation by Buyer. Buyer acknowledges that it is a sophisticated
purchaser of investments and businesses and has been given sufficient access to all information
with respect to the Company and its Subsidiaries requested by it and, in entering into this
Agreement and the Ancillary Agreements, has not relied upon any representations, warranties or
statements other than the representations and warranties of the Company set forth in Article III.
Buyer acknowledges that no other representations and warranties of the Company other than as are
set forth in Article III are required by Buyer to enter into this Agreement or the Ancillary
Agreements.

          Section 4.10 No Other Representations or Warranties. Except for the representations
and warranties contained in this Article IV, neither Buyer nor any other Person makes any other
express or implied representation or warranty on behalf of Buyer.

Buyer and its representatives to have reasonable access, during regular business hours and upon
reasonable advance notice, to the Company and its Subsidiaries and to books and records and the
officers and management employees of the Company and its Subsidiaries to the extent that such
access is necessary for Buyer to consummate the transactions contemplated hereby and does not
unreasonably interfere with the business of the Company or its Subsidiaries; provided that
any information provided hereunder shall remain subject to the Confidentiality Agreements;
provided, further that the foregoing shall not (i) require the Company to permit
any inspection, or to disclose any information, that in its reasonable judgment would result in the

to confidentiality, in the event the Company has attempted, but failed, to obtain a waiver of such
confidentiality obligations, or (ii) require any disclosure by the Company or any of its
Subsidiaries that could, as a result of such disclosure, have the effect of causing the waiver of
any legally recognized privilege so long as the Company has taken reasonable steps to cause such
privilege to be preserved; provided, however, that the parties shall work in good
faith to negotiate agreements or arrangements allowing the disclosure of such information, or
portions thereof. No investigation pursuant to this Section 5.1 or information provided or
received by any party pursuant to this Section 5.1 will affect any of the representations or
warranties of the Parties contained in this Agreement.

its wholly owned Subsidiaries), or securities convertible or exchangeable into or exercisable for
any such equity interests or shares of such capital stock, or any options, warrants or other rights
of any kind to acquire any equity interests or any shares of such capital stock or such convertible
or exchangeable securities;

-24-

 

          (c) reclassify, split, combine or subdivide, directly or indirectly, any of its equity
interests or capital stock or securities convertible or exchangeable into or exercisable for any
equity interests or shares of its capital stock;

          (d) declare, set aside or pay any dividends on, or make any other distributions (whether in
cash, stock or property) in respect of, any of its LLC Units other than Ordinary Course Dividends,
as defined in Section 17(b) of the Amended and Restated LLC Agreement;

          (e) except in the ordinary course of business consistent with past practice and consistent
with customary and prudent practices in the regulated electric delivery industry, initiate any

          (b) Buyer shall not amend, modify, terminate, assign, waive or agree to amend, modify,
terminate, assign or waive any terms of or rights under the Equity Commitment Letters without the
prior written consent of the Company. In the event that all conditions precedent set forth in
Section 6.1 and 6.2 have been satisfied (or waived by Buyer), the Buyer shall cause the other
parties to the Equity Commitment Letters to fund the amounts required to be funded thereunder on
the Closing Date. The Buyer shall take such actions as are necessary to enforce its rights under
the Equity Commitment Letters in the event of breach or noncompliance thereof by any other party
thereto.

          Section 5.4 Filings; Other Actions; Notification. (a) Subject to the terms and
conditions set forth in this Agreement, the Company shall cooperate with Buyer, and Buyer shall
cooperate with the Company, and prior to the Closing each of the Company and Buyer shall use (and

proper or advisable on its part under this Agreement and applicable Laws to consummate and make
effective the transactions contemplated by this Agreement, including to satisfy the conditions

Affiliates) to proffer to, or agree to, sell, divest, lease, license, transfer, dispose of or
otherwise encumber or hold separate and agree to sell, divest, lease, license, transfer, dispose of

efforts to satisfy the condition contained in Section 6.3(e). Subject to applicable Laws relating
to the exchange of information, Buyer and the Company shall have the right to review in advance,

views of the other in connection with, all of the information relating to Buyer, on the one hand,
or the Company on the other hand, and any of their respective Subsidiaries, as the case may be,
that appears in any filing made with, or written materials submitted to, any third party and/or any
Governmental Entity in connection with the transactions contemplated by this Agreement and the
Ancillary Agreements.

          (b) The Company shall, upon request by Buyer, furnish Buyer, and Buyer shall, upon request by

Order; provided that, if legislation discussed in finding of fact 88 of the PUCT Order is
considered in future legislative sessions, Minority Member, Minority Member Parent and their
respective Subsidiaries may participate in that legislative process, either directly or through any
legislative advocacy group in which Minority Member or Minority Member Parent is a member.

related offerings) of equity securities of EFH or any of its Subsidiaries, as the case may be, to
the public or to otherwise list or qualify such securities for trading on any stock exchange at
least 10 Business Days prior to the date of such offering or listing.

securities laws and the LLC Agreement, each LLC Unit certificate held by the Members and their
Permitted Transferees shall bear a legend on the face thereof in the form set forth in Section 6(c)
of the LLC Agreement.

          Section 2.3. Cessation of LLC Membership Interest. A Member shall automatically cease
to be a Member under this Agreement upon a direct Transfer of all of such Member’s LLC Units in
accordance with this Agreement and the LLC Agreement. Following such cessation, a Member shall
have no rights or obligations under the Registration Rights Agreement (other than Sections 7 or 8
thereof, to the extent that they survive following termination of such agreement with respect to a
Member pursuant to Section 12(k) thereof) or

3

 

this Agreement (other than Sections 2.4, 5.5, 5.6 and 5.11, which shall survive any such
cessation or termination of this Agreement).

          Section 2.4. Confidentiality. In furtherance of and not in limitation of any other
applicable agreement such Member may have with the Company, each Member agrees that all
Confidential Information shall be kept confidential by such Member and shall not be disclosed by
such Member in any manner whatsoever; provided, however, that (i) any of such
Confidential Information may be disclosed by a Member to its Affiliates, direct and indirect
shareholders of such Affiliates and Affiliates of such shareholders, managers, directors, officers,
employees and authorized representatives (including attorneys, accountants, consultants, bankers
and financial advisors of such Member) and each Member that is a limited partnership or limited
liability company may disclose such Confidential Information to any former partners or members who
retain an economic interest in such Member, and to any current or prospective partner, limited
partner, member, general partner or management company of such Member (or any employee, attorney,
accountant, consultant, banker or financial advisor or representative of any of the foregoing)
(collectively, for purposes of this Section 2.4, the Member’s “Representatives”) who need
to be provided such Confidential Information to assist such Member in evaluating and managing its
investment in the Company, each of which Representatives shall be bound by the provisions of this
Section 2.4 and shall, if requested by the Company, sign an undertaking agreeing with the Company
to be bound by this Section 2.4 prior to receiving any Confidential Information, (ii) any
disclosure of Confidential Information may be made by a Member or its Representatives to the extent
the Company consents in writing, (iii) Confidential Information may be disclosed by a Member or its
Representatives to a potential transferee (including a Permitted Transferee) and its attorneys,
accountants, consultants, bankers and financial advisors, provided that prior to such
disclosure such potential transferee shall have agreed in writing with the Company to be bound by
the provisions of this Section, and such Member shall be responsible for any breach of this
provision by any such Person, and (iv) Confidential Information may be disclosed by any Member or
Representative to the extent that the Member or its Representative has received advice from its
counsel that it is legally compelled to do so or is required to do so to comply with applicable
law, regulation or a written order of a Governmental Authority, provided that, prior to
making such disclosure, the Member or Representative, as the case may be, uses commercially
reasonable efforts to preserve the confidentiality of the Confidential Information, including, if
legally permitted, consulting with the Board regarding such disclosure and, if reasonably requested
by the Board, assisting the Company, at the Company’s expense, in seeking a protective order to
prevent the requested disclosure, and provided further that the Member or
Representative, as the case may be, discloses only that portion of the Confidential Information as
is, based on the advice of its counsel, required by applicable law, regulation or a written order
of a Governmental Authority.

          Section 2.5. Conflicts with LLC Agreement. In the event of any conflict between the
provisions of this Agreement and the provisions of the LLC Agreement, the provisions of this
Agreement shall prevail to the extent permitted by Law.

Oncor Management Investment LLC or any successor management equity vehicle (“OMI”) in
connection with the Company’s management equity program, (x) to a Permitted Transferee, (y) in a
transaction pursuant to Section 3.3 or a Transfer under a registration statement pursuant to the
Registration Rights Agreement or (z) in any transaction or series of related transactions resulting
in the Transfer of less than 10% of the then outstanding equity interests of the Company or the IPO
Corporation, as the case may be) unless the terms and conditions of such Transfer include an offer,
on the same economic terms and conditions and on other terms and conditions no less advantageous in
the aggregate, as the offer by the proposed third party transferee to the Tag Seller, to each of
the Minority Member and its Permitted Transferees (collectively, the “Tag Offerees”), to
include at the option of each Tag Offeree, in the sale or other Transfer to the third party, a
number of Tag Units owned by each Tag Offeree determined in accordance with this Section 3.2.

          (b) The Tag Seller shall cause such third party transferee offer to be reduced to writing
(which writing shall include an offer to purchase or otherwise acquire Tag Units from the Tag
Offerees as required by this Section 3.2) and shall send written notice of such third party offer
(the “Inclusion Notice”) to each of the Tag Offerees in the manner specified herein, which
Inclusion Notice will include the material terms and conditions of the proposed Transfer, including
(A) the name and address of the proposed transferee, (B) the proposed amount and form of
consideration (and if such consideration consists in part or in whole of property other than cash,
the Tag Seller will provide such information, to the extent reasonably available to the Tag Seller,
relating to such non-cash consideration as the other Members may reasonably request in order to
evaluate such non-cash consideration; provided, however, that the provision of such
information (or lack thereof) shall not affect any Member’s rights under this Section 3.2), (C) the
proposed Transfer date, if known, which date shall not be less than thirty (30) Business Days after
delivery of such Inclusion Notice and (D) the number of Tag Units to be sold or Transferred by the
Tag Seller, the Tag Seller’s Pro Rata Share and the maximum number of Tag Units to be sold or
Transferred to the third party transferee.

          (c) Each Tag Offeree shall have the right (an “Inclusion Right”), exercisable by
delivery of a notice to the Tag Seller at any time within twenty (20) Business Days after receipt
of the Inclusion Notice, to sell or Transfer pursuant to such third party transferee offer, and
upon the terms and conditions set forth in the Inclusion Notice, that number of Tag Units requested
to be included by such Tag Offeree, which number shall not exceed that number of such Tag Offeree’s
Tag Units equal to the product of (i) such Tag Offeree’s Tag Units multiplied

6

 

by (ii) the percentage of the Tag Seller’s Tag Units that the Tag Seller is proposing to sell
or Transfer relative to the total number of Tag Units held by such Tag Seller (the amounts in this
clause (ii), their “Pro Rata Share”) (it being understood that the failure to exercise such
right within such time period specified above shall be deemed to constitute a waiver of all of such
Tag Offeree’s rights with respect to such proposed Transfer (but not with respect to any subsequent
Transfer) and any such exercise of the Inclusion Right shall be irrevocable). If the aggregate
number of Tag Units to be sold or Transferred by the Tag Seller together with the Tag Units to be
sold or Transferred by exercising Tag Offerees and any other Person(s) entitled to tag-along rights
to participate in such sale, exceeds the maximum number of Tag Units to be Transferred to the third
party transferee, as specified in the Inclusion Notice, then the Tag Seller, each exercising Tag
Offeree and each such other Person shall reduce, on a pro rata basis based on their respective
Sharing Percentages (where the specified class of Tag Units referenced in the definition thereof is
all classes of outstanding Tag Units held by the exercising Tag Offerees, Tag Seller and such other
Person(s)), the number of the Tag Units that each otherwise would have been entitled to sell or
Transfer based on the immediately preceding sentence so as to permit the Tag Seller, each
exercising Tag Offeree and each such other Person(s) to sell or Transfer in the aggregate such
maximum amount of Tag Units specified in the Inclusion Notice. In the event that there would
otherwise be a reduction in the number of Tag Units to be sold or Transferred by the Tag Seller,
exercising Tag Offerees and such other Person(s) pursuant to the immediately preceding sentence of
this Section 3.2(c), and the proposed third party transferee is willing to purchase the remaining
securities that the Tag Seller, Tag Offerees and such other Person(s) otherwise would have sold or
Transferred if there had been no such reduction (the “Reduction Units”), the Tag Seller,
Tag Offerees and such other Person(s) shall be entitled to sell or Transfer the Reduction Units to
the proposed third party transferee, upon the terms and conditions set forth in the Inclusion
Notice. The exercising Tag Offerees and the Tag Seller shall sell or Transfer to the proposed
third party transferee the Tag Units proposed to be Transferred by them in accordance with this
Section 3.2 at the time and place provided for the closing in the Inclusion Notice, or at such
other time and place as the holders of a majority of the Tag Units to be Transferred by exercising
Tag Offerees, the Tag Seller, and such other Person(s) and the proposed third party transferee
shall agree. Notwithstanding the foregoing, no Tag Offeree shall be entitled to Transfer Tag Units
pursuant to an Inclusion Right conferred pursuant to this Section 3.2 in the event that,
notwithstanding delivery of an Inclusion Notice pursuant to this Section 3.2, the Tag Seller fails
to consummate the Transfer of Tag Units which gave rise to such Inclusion Right.

          (d) The Tag Seller shall, in its sole discretion, decide whether or not to pursue, consummate,
postpone or abandon any proposed Transfer and the terms and conditions thereof. No Member or any
Affiliate thereof or direct or indirect shareholder of any such Member or Affiliate or any
Affiliates of such shareholders shall have any liability to any other Member, the Company or the
IPO Corporation arising from, relating to or in connection with the pursuit, consummation,
postponement, abandonment or terms and conditions of any such proposed Transfer except to the
extent such Member shall have failed to comply with the provisions of this Section 3.2.

          (e) Notwithstanding anything herein to the contrary, no Tag Offeree shall have an Inclusion
Right in connection with any Transfer, if and to the extent making available or exercising such
Inclusion Right, if applicable to such sale or Transfer, would require the relevant

7

 

third party transferee to (i) register under applicable securities Laws the securities to be
issued to the Tag Seller, the Tag Offerees or other participating Persons or the securities of such
third party transferee, or (ii) effect a “private placement” in lieu of such registration that does
not satisfy the requirements of Regulation D under the Securities Act.

          (f) In connection with any such Transfer, each Tag Offeree and other Person(s) participating
in such Transfer must agree to make the same representations, warranties, covenants and indemnities
as the Tag Seller; provided, that (x) no such Tag Offeree shall be required to make
representations and warranties or covenants or provide indemnities as to any other Member or other
participating Person(s) and no such Tag Offeree shall be required to make any representations and
warranties (but, subject to clause (z), may be required to provide several but not joint
indemnities with respect to breaches of representations and warranties made by or in respect of the
Company or its Subsidiaries or the IPO Corporation or its Subsidiaries, as the case may be)
regarding the business of the Company or its Subsidiaries or the IPO Corporation or its
Subsidiaries, as the case may be, (y) no Tag Offeree shall be liable for the breach of any covenant
by any other Tag Offeree, Member or other participating Person(s) and (z) notwithstanding anything
in this Section 3.2(f) to the contrary, any liability relating to representations and warranties
(and related indemnities), covenants or other indemnification obligations regarding the business of
the Company or its Subsidiaries or the IPO Corporation or its Subsidiaries, as the case may be,
assumed in connection with the Transfer shall be shared by all exercising Tag Offerees electing to
sell, the Tag Seller and such other Person(s) entitled to tag-along rights participating in such
sale pro rata in proportion to the number of Tag Units to be actually Transferred by each of those
Members or other participating Person(s) and in any event shall not exceed the proceeds received by
such Member or other participating Person(s) in the proposed Transfer. Each Tag Offeree
participating in such Transfer will be responsible for its proportionate share of the costs of the
proposed Transfer to the extent not paid or reimbursed by the proposed third party transferee.

          (g) If the closing of the Transfer to the proposed third party transferee (whether or not any
Tag Offeree has exercised its rights under this Section 3.2) shall not have occurred 120 days after
the date of the Inclusion Notice (or such longer period, not to exceed 180 days after the date of
the Inclusion Notice, if extended by the Tag Seller pursuant to Section 3.2(i)(iii)), the
provisions of this Section 3.2 shall again be required to be complied with, with respect to such
Tag Units.

          (h) In the event that EFH or any of its Subsidiaries proposes to Transfer LLC Units or IPO
Units, as the case may be, indirectly through a Transfer of equity interests in a Subsidiary of EFH
the sole or principal asset of which is such LLC Units or IPO Units (other than (w) to OMI in
connection with the Company’s management equity program, (x) to a Permitted Transferee of EFH, (y)
in a transaction pursuant to Section 3.3 or a Transfer under a registration statement filed
pursuant to the Securities Act or (z) in any transaction or series of related transactions
resulting in the direct or indirect Transfer of less than 10% of the then outstanding equity
interests of the Company or the IPO Corporation, as the case may be) and such Transfer would not
trigger the issuance of an Inclusion Notice to the Tag Offerees pursuant to the terms of this
Section 3.2, EFH or any of its Subsidiaries, as applicable, shall cause (i) an offer to be made to
each Tag Offeree to Transfer a portion of its LLC Units or IPO Units, as the case may be, equal to
the number of such securities that such Tag Offeree would have been

8

 

permitted to Transfer pursuant to this Section 3.2 if the proposed Transfer had been effected
as a direct Transfer by a Related Entity (the “Equivalent Offer”) and (ii) the terms of the
Equivalent Offer to be in all material respects substantially similar in the aggregate to those
terms that would have been offered to each Tag Offeree pursuant to the terms of this Section 3.2 if
the proposed Transfer had been effected as a direct Transfer by a Related Entity.

          (i) Notwithstanding any other provision in this Section 3.2, in the event that the proposed
Transfer to which an Inclusion Notice pursuant to this Section 3.2 relates or an Equivalent Offer
is conditional upon or includes the sale by the Tag Seller, EFH, Parent or any of their
Subsidiaries of any of their material assets in addition to Tag Units, LLC Units or IPO Units, as
the case may be, then, in addition to the items required pursuant to Section 3.2(b), the following
provisions shall apply:

     (i) The Inclusion Notice or the notice of an Equivalent Offer made pursuant to
Section 3.2(h) shall specify the proposed allocation of the consideration in respect
of such sale or Transfer as between such other assets, on the one hand, and the Tag
Units, LLC Units or IPO Units, on the other hand, to be sold or Transferred to the
proposed transferee, together with a description, in reasonable detail, of the
reasons underlying such proposed allocation;

     (ii) Following receipt of such an Inclusion Notice or the notice of an
Equivalent Offer made pursuant to Section 3.2(h), each exercising Tag Offeree shall
have the option, exercisable by written notice to the Tag Seller or EFH, as the case
may be, within ten (10) Business Days of receiving such notice, to require that the
fair allocation of purchase price to the Tag Units, LLC Units or IPO Units, as the
case may be, directly or indirectly held by the Tag Seller or EFH, as applicable,
and such other material assets, in each case, to be sold by the Tag Seller, EFH or
Parent in such sale be determined pursuant to an independent appraisal process;

     (iii) If this option is so exercised,

     (A)   the Tag Seller or EFH, as the case may be, shall have the option,
to be exercised in its sole discretion, to determine whether to (1) await
the outcome of the Tag Appraiser (as defined below) prior to proceeding with
any sale or Transfer pursuant to this Section 3.2 and, if so desired, to
extend the proposed time period for the closing of such sale or Transfer to
a date not later than 180 days after the date of the Inclusion Notice or its
equivalent pursuant to Section 3.2(h), as applicable or (2) proceed with the
closing of such sale or Transfer upon the original proposed closing date,
whether or not the decision of the Tag Appraiser has been rendered as of
such time (and, for the avoidance of doubt, any such Tag Offeree exercising
its rights to participate in such sale or Transfer shall be obligated to
complete such sale or Transfer on the same day as the Tag Seller or EFH, as
the case may be); and

9

 

     (B)   the Tag Seller or EFH, as the case may be, on the one hand, and
such exercising Tag Offeree, on the one hand, shall jointly appoint (by
mutual agreement, or failing such agreement, by lot from among four
qualified institutions two of which are designated by each of the two
participants) a nationally-recognized appraiser with experience valuing
utility companies (the “Tag Appraiser”) to determine the fair
allocation of purchase price to the Tag Units, LLC Units or IPO Units, as
the case may be and such other material assets, in each case, to be sold by
the Tag Seller or EFH in such sale; provided, that in each case any
such determinations shall in all respects be made on a going concern basis
for the relevant business(es), assuming a willing purchaser and a willing
buyer, with no control premium and no discount for a minority interest in
respect of such assets of EFH, Parent or any of their Subsidiaries or the
Tag Units, LLC Units, or IPO Units, as the case may be.

     (iv) Notwithstanding any other provision of this Section 3.2, in the event that
an exercising Tag Offeree exercises its rights under this Section 3.2(i), the
consideration payable to the Tag Offerees so exercising their rights under this
Section 3.2(i) in respect of their Tag Units, LLC Units or IPO Units pursuant to the
sale or Transfer contemplated by this Section 3.2 shall be based on a per Unit price
derived from the fair allocation attributable to the Tag Units, LLC Units or IPO
Units, as the case may be, determined by the Tag Appraiser, notwithstanding the
allocation (and underlying per Unit price) that was specified in the Inclusion
Notice or a notice of Equivalent Offer made pursuant to Section 3.2(h);
provided, for greater certainty, that, in the event that the Tag Seller or
EFH, as the case may be, has elected to proceed with the closing of the sale or
Transfer prior to receipt from the Tag Appraiser of its allocation, the Tag Seller
or EFH, as the case may be, shall be solely responsible for payment of any
consideration determined by the Tag Appraiser to be payable to Tag Offerees pursuant
to the sale or Transfer in accordance with this Section 3.2(i), if and to the extent
this amount exceeds the consideration payable to such Tag Offerees that was
specified in the Inclusion Notice or a notice of Equivalent Offer made pursuant to
Section 3.2(h).

     (v) The parties shall use reasonable efforts to provide that the Tag Appraiser
render its final determination in writing prior to the closing of such sale or
Transfer contemplated by this Section 3.2. The final written determination of the
Tag Appraiser shall be final and binding on EFH, the Initial Member and each Tag
Offeree exercising its rights under this Section 3.2(i), as applicable, absent
manifest error, and shall modify the allocation of consideration payable in such
sale or other Transfer pursuant to this Section 3.2, solely as between such
applicable Persons. In the event that any such final determination is made prior to
the closing of such sale or other Transfer, the consideration payable in such sale
or other Transfer shall be reallocated as appropriate to reflect such final
determination. In the event that any such final determination is made following the
closing of such sale or other Transfer, a payment in cash of the applicable
corrective payment required by such final determination shall be made, by wire
transfer of immediately available funds within five Business Days following

10

 

receipt of such final determination from the Tag Appraiser, by the Tag Offerees
exercising their rights under this Section 3.2(i) to EFH or the Initial Member, as
applicable, or by EFH or the Initial Member, as applicable, to the Tag Offerees
exercising their rights under this Section 3.2(i) to an account specified in writing
by the recipient at least one Business Day prior to such payment date.

     (vi) In the event that the decision of the Tag Appraiser results in an amount
of consideration per Unit payable to the applicable Tag Offerees exercising their
rights under this Section 3.2(i) that exceeds the implied per Unit amount that was
specified in the Inclusion Notice or its equivalent pursuant to Section 3.2(h) by
more than 10.0%, then the Tag Seller or EFH, as the case may be, shall be
responsible for the costs and expenses of the Tag Appraiser. In the event that the
decision of the Tag Appraiser results in an amount of consideration payable to the
applicable Tag Offerees that is less than 110.0% of the implied per Unit amount that
was specified in the Inclusion Notice or notice of an Equivalent Offer pursuant to
Section 3.2(h), then the Tag Offeree(s) that elected to require an allocation to be
prepared shall be responsible for the costs and expenses of the Tag Appraiser.

          (j) The provisions of this Section 3.2 shall terminate upon the earlier of (x) completion of a
Qualified IPO and (y) the date seven years from the date hereof.

          Section 3.3. Drag-Along Rights

          (a) Notwithstanding anything contained in this Article III to the contrary, but subject to
Section 3.3(f), if (i) Parent, EFH or its Subsidiaries (other than the Initial Member (or its
Permitted Transferee(s)) receives an offer to purchase (an “EFH Sale Proposal”) a number of
LLC Units or IPO Units, as the case may be, held directly or indirectly by such entities and LLC
Units or IPO Units, as the case may be, owned directly by Members other than the Initial Member (or
its Permitted Transferee(s)) (the “EFH Drag Units”) or (ii) if the Initial Member (or its
Permitted Transferee(s)) receives an offer to purchase (an “Initial Member Sale Proposal”)
a number of LLC Units or IPO Units, as the case may be, including LLC Units or IPO Units, as the
case may be, owned by Members other than the Initial Member (or its Permitted Transferee(s)) (the
“Initial Member Drag Units” and together with the EFH Drag Units, the “Drag Units”)
such that the transaction would result in a Change of Control (taking into account all LLC Units or
IPO Units being “dragged”) (each, a “Required Sale”), then EFH or the Initial Member (on
its own behalf or on behalf of its Permitted Transferee(s)), as the case may be, may deliver a
written notice (a “Required Sale Notice”) with respect to such EFH Sale Proposal or Initial
Member Sale Proposal at least twenty (20) Business Days prior to the anticipated closing date of
such Required Sale to all Members (other than the Initial Member (or its Permitted Transferee(s)))
requiring them to sell or otherwise Transfer their Drag Units to the proposed transferee in
accordance with the provisions of this Section 3.3.

          (b) The Required Sale Notice will include the material terms and conditions of the Required
Sale, including (A) the name and address of the proposed transferee, (B) the proposed amount and
form of consideration (and if such consideration consists in part or in whole of property other
than cash, the issuer of the Required Sale Notice will provide such

11

 

information, to the extent reasonably available to such issuer, relating to such non-cash
consideration as the other Members may reasonably request in order to evaluate such non-cash
consideration; provided, however, that the provision of such information (or lack
thereof) shall not relieve any Member of its obligation to sell or otherwise Transfer Drag Units
under this Section 3.3) and (C) the proposed Transfer date, if known. The issuer of the Required
Sale Notice will deliver or cause to be delivered to each other Member copies of all transaction
documents relating to the Required Sale promptly as the same become available.

          (c) Each Member, upon receipt of a Required Sale Notice, shall be obligated to sell or
otherwise Transfer the proportion of its Drag Units specified by the issuer of the Required Sale
Notice (which proportion shall be the same for all Members) and participate in the Required Sale
contemplated by the EFH Sale Proposal or Initial Member Sale Proposal, to vote, if required by this
Agreement, the LLC Agreement or otherwise, its Drag Units in favor of the Required Sale at any
meeting of Members called to vote on or approve the Required Sale and/or to consent in writing to
the Required Sale, to use its reasonable efforts to cause any individuals designated or nominated
by such Member to the Board to vote in favor of the Required Sale in a vote amongst the Board
called to vote on or approve the Required Sale and/or to consent in writing to the Required Sale,
to, subject to Section 3.3(f), waive all dissenters’ or appraisal rights, if any, in connection
with the Required Sale, to enter into agreements relating to the Required Sale, to agree (as to
itself) to make to the proposed purchaser the same representations, warranties, covenants,
indemnities and agreements as any direct or indirect holders of LLC Units or IPO Units, as the case
may be, that are Affiliates of EFH agree to make in connection with the Required Sale, and to take
or cause to be taken all other actions as may be reasonably necessary to consummate the Required
Sale; provided, that (x) unless otherwise agreed by such Member, a Member may not be
required to make representations and warranties or provide indemnities as to any other Member, or
make any representations and warranties (but, subject to clause (z), shall be required to provide
several but not joint indemnities with respect to breaches of representations and warranties made
by or in respect of the Company or its Subsidiaries or the IPO Corporation or its Subsidiaries, as
the case may be) about the business or operations of the Company or its Subsidiaries or the IPO
Corporation or its Subsidiaries, as the case may be, (y) no such Member shall be liable for the
breach of any covenant by any other Member and (z) notwithstanding anything in this Section 3.3(c)
to the contrary, any liability relating to representations and warranties (and related indemnities)
and other indemnification obligations regarding the business of the Company or its Subsidiaries or
the IPO Corporation or its Subsidiaries, as the case may be, assumed in connection with the
Required Sale shall be shared by all Members pro rata based on their respective Drag Units being
sold or Transferred in the Required Sale and in any event shall not exceed the proceeds received by
such Member in the Required Sale.

          (d) The obligations of the Members pursuant to this Section 3.3 are subject to the
satisfaction of the following conditions:

     (i) subject to Section 3.3(f), each of the Members shall receive the same type
and amount of consideration (except, in the case of a Required Sale in which the
consideration to be received by the sellers or transferors consists of both cash and
securities, to the extent that any Members other than the Minority Member and its
Permitted Transferees agree to accept a disproportionate share of

12

 

securities in order to allocate a greater portion of cash to the Minority
Member and/or its Permitted Transferees due to restrictions described in clause (ii)
immediately below on the ability of the Minority Member and/or its Permitted
Transferees to hold such securities), at the same time, on a per Drag Unit basis,
and shall participate in such Required Sale on terms and conditions no less
favorable in the aggregate than those offered to the other Members;

     (ii) the consideration payable to the Minority Member and its Permitted
Transferees pursuant to the Required Sale shall be (x) cash, and/or (y) except as
prohibited by applicable Law or as prohibited by the written statement of investment
policies governing OMERS Administration Corporation, Borealis Infrastructure
Management Inc., GIC, and the investment policies of their wholly-owned Subsidiaries
to the extent relevant to the type of asset being received, in effect immediately
prior to delivery of the relevant Required Sale Notice, Marketable Securities,
and/or (z) any other securities with the Minority Member’s (or, if applicable, its
Permitted Transferees’) prior written consent;

     (iii) without the consent of the Minority Member or its Permitted Transferee
(such consent not to be unreasonably withheld, delayed or conditioned), the Required
Sale will not require that the Minority Member or its Permitted Transferees be
subject to non-compete covenants that would restrict its business activities in any
material respect;

     (iv) subject to Section 3.3(f), any expenses incurred for the benefit of the
Company or all Members and any indemnities, holdbacks, escrows and similar items
relating to the Required Sale, that are not paid or established by the Company or
the IPO Corporation or its Subsidiaries, as the case may be, (other than those that
relate to representations or indemnities concerning a Member’s valid ownership of
its Drag Units free and clear of all liens, claims and encumbrances or a Member’s
authority, power and legal right to enter into and consummate a purchase or merger
agreement or ancillary documentation) shall be paid or established by the Members in
accordance with their respective Sharing Percentages; and

     (v) notwithstanding anything in this Section 3.3(d) to the contrary, any
liability relating to representations and warranties (and related indemnities) and
other indemnification obligations regarding the business of the Company or its
Subsidiaries or the IPO Corporation or its Subsidiaries, as the case may be, assumed
for which a Member is liable shall not exceed the proceeds received by such Member
in the Required Sale.

In addition to the conditions described in clauses (i) through (v) immediately above, none of the
Minority Member or any of its Permitted Transferees who are Members shall be obligated to sell or
otherwise Transfer their LLC Units or IPO Units (or otherwise satisfy their obligations pursuant to
Section 3.3(c)) in a Required Sale unless the Minority Member would have achieved an IRR on its
initial investment in LLC Units acquired pursuant to the Contribution and Subscription Agreement of
no less than 10.0% as of immediately after consummation of such

13

 

Required Sale (calculated (x) as if the Minority Member had received its proceeds in respect of
such Required Sale; (y) treating all proceeds and distributions in respect of the LLC Units and IPO
Units held (and/or previously held, as applicable) by each of the Minority Member’s Permitted
Transferees as proceeds received by the Minority Member; and (z) assuming completion of such
Required Sale by the target closing date mutually agreed by the parties to the Required Sale) (the
“IRR Hurdle”); provided that in the event that the IRR Hurdle is not met but EFH or
the Initial Member (or their respective Affiliates), as applicable, proceeds with such Required
Sale (in which the Minority Member and its Permitted Transferees shall accordingly not be obligated
to Transfer LLC Units or IPO Units), then the Minority Member shall nevertheless be required to, if
so requested by the proposed transferee, agree to amend the LLC Agreement and, if applicable, this
Agreement (effective as of or after the closing of such Required Sale) to reflect terms and
conditions substantially equivalent to those set forth in Schedule 3.3(d) hereto (and to
delete any corresponding conflicting or inconsistent terms then existing in the LLC Agreement or
this Agreement).

          (e) The issuer of the Required Sale Notice shall, in its sole discretion, decide whether or
not to pursue, consummate, postpone or abandon any Required Sale and, subject to Section 3.3(c) and
3.3(d), the terms and conditions thereof. No Member or any Affiliate or direct or indirect
shareholder of any such Member or Affiliate or any Affiliates of such shareholders shall have any
liability to any other Member, the Company or the IPO Corporation arising from, relating to or in
connection with the pursuit, consummation, postponement, abandonment or terms and conditions of any
Required Sale except to the extent such Member shall have failed to comply with the provisions of
this Section 3.3.

          (f) Notwithstanding any other provision in this Section 3.3, in the event that the Required
Sale is conditional upon or includes the sale by Parent or its Subsidiaries of any of their
material assets (other than the Drag Units), then, in addition to the items required pursuant to
Section 3.3(b), the following provisions shall apply:

     (i) The Required Sale Notice shall specify the proposed allocation of the
purchase price in respect of such transaction as between such other assets and the
Drag Units to be sold or Transferred to the proposed transferee, together with a
description, in reasonable detail, of the reasons underlying such proposed
allocation;

     (ii) Following receipt of such a Required Sale Notice, the Minority Member or
its Permitted Transferee shall have the option, exercisable by written notice to EFH
or the Initial Member, as the case may be, within ten (10) Business Days of
receiving the Required Sale Notice, to require that the fair allocation of purchase
price to the Drag Units and such other material assets be determined pursuant to an
independent appraisal process. If this option is so exercised, EFH or the Initial
Member, on the one hand, and the Minority Member or its Permitted Transferee, on the
other hand, shall jointly appoint (by mutual agreement, or failing such agreement,
by lot from among four qualified institutions two of which are designated by each of
the two participants) a nationally-recognized appraiser with experience valuing
utility companies (the “Drag Appraiser”) to determine the fair allocation of
purchase price to the Drag Units and other

14

 

material assets; provided, that in each case any such determinations shall in
all respects be made on a going concern basis for the relevant business(es),
assuming a willing purchaser and a willing buyer, with no control premium and no
discount for a minority interest;

     (iii) Notwithstanding any other provision of this Section 3.3, the
consideration payable to Members (other than EFH or Affiliates of EFH) pursuant to
the Required Sale shall be the fair allocation to their Drag Units determined by the
Drag Appraiser, notwithstanding the consideration payable to such Members that was
specified in the Required Sale Notices; provided, for greater certainty,
that EFH or the Initial Member, as the case may be, shall be solely responsible for
payment of any consideration determined by the Drag Appraiser to be payable to
Members (other than EFH or Affiliates of EFH) pursuant to the Required Sale in
accordance with this Section 3.3(f), if and to the extent this amount exceeds the
consideration payable to such Members that was specified in the Required Sale
Notice;

     (iv) The parties shall use reasonable efforts to provide that the Drag
Appraiser render its final determination in writing prior to the closing of such
Required Sale. The final written determination of the Drag Appraiser shall be final
and binding on EFH, the Initial Member, the Minority Member and its Permitted
Transferees, as applicable, absent manifest error, and shall modify the allocation
of consideration payable in such Required Sale, solely as between such applicable
Persons. In the event that any such final determination is made prior to the
closing of such Required Sale, the consideration payable in such Required Sale shall
be reallocated as appropriate to reflect such final determination. In the event
that any such final determination is made following the closing of such Required
Sale, a payment in cash of the applicable corrective payment required by such final
determination shall be made, by wire transfer of immediately available funds within
five Business Days following receipt of such final determination from the Drag
Appraiser, by the Minority Member and/or its Permitted Transferees, as applicable,
to EFH or the Initial Member, as applicable, or by EFH or the Initial Member, as
applicable, to the Minority Investor and/or its Permitted Transferees, as
applicable, in each case to an account specified in writing by the recipient at
least one Business Day prior to such payment date; and

     (v) In the event that the decision of the Drag Appraiser results in an amount
of consideration payable to Members (other than EFH or Affiliates of EFH) that
exceeds the amount that was specified in the Required Sale Notice, then EFH or the
Initial Member, as the case may be, shall be responsible for the costs and expenses
of the Drag Appraiser. In the event that the decision of the Drag Appraiser results
in an amount of consideration payable to Members (other than EFH or Affiliates of
EFH) that equals or is less than the amount that was specified in the Required Sale
Notice, then the Member that elected to require a valuation to be prepared shall be
responsible for the costs and expenses of the Drag Appraiser.

15

 

          (g) The provisions of this Section 3.3 shall terminate upon the eighteen (18) month
anniversary of the completion of a Qualified IPO.

          Section 3.4. Other Transfer Restrictions

          (a) In addition to any other restrictions on Transfer herein contained, in no event may any
Transfer of any LLC Units by any Member be made (other than sales pursuant to, and in accordance
with, Sections 3.2 and 3.3):

     (i) if such Transfer would be reasonably likely to cause the Company to cease
to be classified as a partnership for U.S. federal or state income tax purposes;

     (ii) if such Transfer would require the registration of such LLC Units pursuant
to any applicable foreign, federal, provincial or state securities Laws;

     (iii) if such Transfer would be reasonably likely to cause the Company to
become a “Publicly Traded Partnership,” as such term is defined in Section 469(k)(2)
or Section 7704(b) of the Code or would result in the Company having more than 100
Members at any time during any taxable year of the Company within the meaning of
Treasury Regulations 1.7704-1(h)(1)(ii);

     (iv) if such Transfer would subject the Company, its Members or any of their
Affiliates to regulation under the Investment Company Act of 1940, as amended, or
Title I of ERISA, or would subject the Company, its Members or any of their
Affiliates to regulation under the Investment Advisers Act of 1940, as amended;

     (v) unless the transferee makes the representations and warranties set forth in
Section 4.1;

     (vi) if such Transfer would result in a violation of any applicable Law, and
for the avoidance of doubt, Law includes applicable securities, ERISA, or antitrust
Laws;

     (vii) if such Transfer would require the Company or any of its Subsidiaries to
obtain any licensing or regulatory consent other than any such license or regulatory
consent that is immaterial or ministerial in nature;

     (viii) if such Transfer would reasonably be expected to have an adverse
regulatory impact (other than an immaterial impact) (as determined by the Board
after consultation with counsel) on the Company or any of its Affiliates; or

     (ix) if such Transfer is made to any Person who lacks the legal right, power or
capacity to own such interest;

provided, that prior to any Transfer of LLC Units, the Initial Member may waive the
restrictions on Transfer contained in Sections 3.4(a)(ii) and (vii) with respect to such Transfer.

16

 

          (b) Unless admitted as a Member and made a party hereto, no transferee, whether by a voluntary
transfer, by operation of Law or otherwise, shall have rights hereunder.

          (c) Except as otherwise provided herein, the Transferring Members effecting any Transfer of
LLC Units or IPO Units, as the case may be, permitted hereunder shall pay all reasonable costs and
expenses, including attorneys’ fees and disbursements, incurred by the Company in connection with
the Transfer on a pro rata basis in proportion to the number of LLC Units so transferred by each
such Member.

          Section 3.5. Substituted Members

          (a) No Member party hereto shall have the right to substitute a transferee as a Member in its
place with respect to any LLC Units so Transferred unless such Transfer is made in compliance with
the terms of this Agreement, including Section 3.1 and Section 3.4, and the LLC Agreement.

          (b) A Permitted Transferee of a Member who has been admitted as a substituted member in
accordance with this Section 3.5 (a “Substituted Member”) shall have all the rights and
powers and be subject to all the restrictions and liabilities of the Transferring Member with
respect to the LLC Units Transferred under this Agreement. No purported assignment or Transfer of
any Member’s rights or obligations under this Agreement shall be effective other than as provided
in this Section 3.5(b).

          (c) Admission of a Substituted Member shall become effective on the date such Person executes
an Addendum Agreement of this Agreement or a counterpart of this Agreement and any other documents
required under the LLC Agreement.

          Section 3.6. Preemptive Rights

          (a) Prior to an IPO, if the Company proposes to issue additional equity securities (including
securities exercisable or exchangeable for or convertible into equity securities, such securities
“Equity Securities”) of the Company or any Subsidiary of the Company proposes to issue
additional Equity Securities, the Company shall deliver to the Initial Member, the Minority Member
and their respective Permitted Transferees then holding LLC Units (each, a “Participating
Member”, or, collectively, the “Participating Members”) a written notice of such
proposed issuance at least thirty (30) days prior to the date of the proposed issuance (the period
from the effectiveness pursuant to Section 5.1 of such notice until the date of such proposed
issuance, the “Subscription Period”). Such notice shall include the material terms and
conditions of the issuance, including, to the extent applicable, (i) the identity of the issuer,
(ii) the amount, kind and terms of the Equity Securities to be included in the issuance, (iii) the
maximum and minimum price of the equity securities to be included in the issuance, (iv) the name
and address of the proposed purchaser and (v) the proposed issuance date, if known.

          (b) Each Participating Member shall have the option, exercisable at any time during the first
twenty (20) days of the Subscription Period by delivering an irrevocable written notice to the
Company (except as otherwise provided in this Section 3.6) and on the same terms and conditions as
those of the proposed issuance of such additional Equity Securities (including the number or
amount, as applicable, of equity securities issuable upon exercise, exchange or

17

 

conversion of any Equity Security), to irrevocably subscribe for up to such number or amount,
as applicable, of Equity Securities included in the proposed issuance as is equal to the product of
(A) the number or amount of any such additional Equity Securities to be offered and (B) a fraction
the numerator of which is the number of LLC Units owned by such Participating Member and the
denominator of which is the total number of LLC Units owned by all Members (in each case,
calculated on a fully diluted basis) (the “Preemptive Percentage”). Each Participating
Member who does not exercise any portion of such option in accordance with the above requirements
shall be deemed to have waived all of such Participating Member’s rights with respect to such
issuance, but not with respect to any future issuance.

          (c) If, prior to consummation of the issuance of equity securities covered by this Section
3.6, the terms of the proposed issuance change with the result that the price is less than the
minimum price or more than the maximum price set forth in the notice contemplated by clause (a)
above or the other principal terms are materially more favorable to the prospective purchaser than
those set forth in such notice, it shall be necessary for a separate notice to be furnished, and
the terms and provisions of this Section 3.6 shall be separately complied with.

          (d) If at the end of the 90th day after the date of the effectiveness of the notice
contemplated by clause (a) above as such period may be extended to obtain any required regulatory
approvals, the Company or any Subsidiary of the Company, as applicable, has not completed the
issuance, each Participating Member shall be released from such Participating Member’s obligations
under the written commitment, the notice shall be null and void, and it shall be necessary for a
separate notice to be furnished, and the terms and provisions of this Section 3.6 shall be
separately complied with, in order to consummate such issuance.

          (e) In the event that the participation in the issuance by a Participating Member as a
purchaser would require under applicable Law (i) the registration or qualification of such
securities or of any Person as a broker or dealer or agent with respect to such securities where
such registration or qualification is not otherwise required for the issuance or (ii) the provision
to any Participating Member of any specified information regarding the Company or any of its
Subsidiaries or the securities to be issued that is not otherwise required to be provided for the
issuance, such Participating Member shall not have the right to participate in the issuance.

          (f) Each Participating Member shall take or cause to be taken all such reasonable actions as
may be necessary or reasonably desirable in order expeditiously to consummate each issuance
pursuant to this Section 3.6.

          (g) Notwithstanding the requirements of this Section 3.6, the Company or any Subsidiary of the
Company, as applicable, may proceed with any issuance that would otherwise be subject to this
Section 3.6 prior to having complied with the provisions of this Section 3.6; provided,
that the Company or any such Subsidiary of the Company, as applicable, shall:

     (i) provide to each Member in connection with such issuance (A) prompt notice
of such issuance and (B) the notice described in clause (a) above in which the
actual price of the Equity Securities shall be set forth;

18

 

     (ii) within a reasonable period of time following the issuance, offer to issue
(or have Transferred) to each Member such number or amount of Equity Securities of
the type issued in the issuance as may be requested by such Member (not to exceed
the number or amount of Equity Securities which is sufficient to give such Member
the same fractional interest in the Company, and/or indirect interest in the
Company’s Subsidiaries, giving effect to such issuance and any further issuances
pursuant to this clause (g), as it would have had if the Company had served a notice
pursuant to, and such Member had exercised its rights in full under, Section 3.6(b)
prior to the issuance) on the same terms and conditions with respect to such Equity
Securities as the subscribers in the issuance received; and

     (iii) keep such offer open for a period of thirty (30) Business Days, during
which period, each such Member may accept such offer by sending an irrevocable
written acceptance to the Company or any Subsidiary of the Company, as applicable,
committing to purchase in accordance with the procedures set forth in Section
3.6(b), an amount of such securities (not to exceed the amount specified in the
offer made pursuant to Section 3.6(g)(ii)).

          (h) The provisions of this Section 3.6 shall not apply to any of the following issuances by
the Company or any Subsidiary of the Company:

     (i) any issuance of Equity Securities, (A) in any direct or indirect business
combination or acquisition transaction involving the Company or any of its
Subsidiaries, including with respect to a Change of Control, (B) in connection with
any joint venture or strategic partnership entered into by the Company or (C) to
financial institutions, commercial lenders, broker/finders or any similar party, or
their respective designees, in connection with the incurrence or guarantee of
indebtedness by the Company or any of its Subsidiaries;

     (ii) any issuance of Equity Securities to, or for the benefit of, officers,
directors, employees or consultants of the Company or its Subsidiaries in connection
with their employment with or service to the Company or its Subsidiaries, including
issuances of Equity Securities to OMI;

     (iii) any issuance of Equity Securities in connection with any stock or limited
liability company interest split or stock or limited liability company interest
dividend or recapitalization paid on a proportionate basis to all holders of the
affected class of equity interest or recapitalization approved by the Board (or the
governing body of the entity making such issuance) that is not materially and
disproportionately adverse to any Member relative to any other Member in their
capacity as Members; or

     (iv) any issuance of Equity Securities in connection with the IPO Conversion or
an IPO.

19

 

          Section 3.7. Conversion to IPO Corporation

          (a) Subject to the terms of the LLC Agreement and Section 3.7(c), EFH may develop and
implement an IPO Conversion (as defined below) and each Member shall cooperate in respect thereof.
In connection therewith, but subject to the provisions of Section 3.7(c), the Board may, at the
request of EFH, take any and all actions to create and implement an IPO Conversion, including (i)
amendment of the LLC Agreement, including amendments that alter the capital structure of the
Company, whether through the issuance, conversion or exchange of equity securities or otherwise,
(ii) the merger, conversion or consolidation of the Company, (iii) the formation of Subsidiaries
and the distribution to Members of equity or other interests in such Subsidiaries, including in
exchange for such Members’ LLC Units, (iv) transferring, domesticating or otherwise moving the
Company to another jurisdiction, (v) preparing an existing Affiliate of the Company (the material
assets of which consist only of its direct or indirect interest in the Company) to be a publicly
traded entity and (vi) taking such other steps as it deems necessary, advisable or convenient to
create a suitable vehicle for an offering (the resulting entity, the “IPO Corporation”), in
each case for the express purpose of an initial offering of the securities of such IPO Corporation
for sale to the public in an IPO (any such action, an “IPO Conversion”). In connection
therewith, but subject to the provisions of Section 3.7(c), the Company and each Member agree to
cooperate with the other Members in good faith in order to effectuate the IPO Conversion (including
giving any consents required to effect the IPO Conversion pursuant to the LLC Agreement) and ensure
that each Member receives shares of common stock (or other equity securities) or the right to
receive shares of common stock (or other equity securities), and other rights in connection with
such IPO Conversion substantially equivalent to, and in exchange for, its economic interest,
governance, priority and other rights and privileges as such Member had with respect to its LLC
Units prior to such IPO Conversion and are consistent with the rights and preferences attendant to
such LLC Units as set forth in the LLC Agreement as in effect immediately prior to such IPO
Conversion and to ensure that such rights and privileges are reflected in the organizational and
other documents of the IPO Corporation, including entering into a stockholders or similar agreement
containing restrictions on transfer of such shares and such other rights and obligations as are
provided for herein with respect to the LLC Units and EFH shall cause any Related Entity that is a
Subsidiary of EFH (other than the Initial Member) to enter into such shareholders or similar
agreement. Furthermore, in connection with, and prior to any IPO, the Company shall cause the IPO
Corporation to become a party to and bound by the Registration Rights Agreement in respect of the
IPO Units.

          (b) The Company shall give each Member at least sixty (60) days’ prior written notice of any
IPO Conversion. If EFH elects to undertake an IPO Conversion, the Members shall, subject to the
provisions of Section 3.7(c), take such actions as may be reasonably required and otherwise
cooperate in good faith with the Company, including taking all actions reasonably required by the
Company in connection with consummating the IPO Conversion (including the voting of any LLC Units
in connection with any matters relating to the IPO Conversion (recognizing that this Agreement
authorizes the Company to create and implement the IPO Conversion without the need for any such
consent, provided that Section 3.7(c) is complied with) and using its reasonable efforts to cause
any individuals designated or nominated by such Member to the Board to vote in favor of the IPO
Conversion in a vote

20

 

amongst the Board called to vote on or approve the IPO Conversion and/or to consent in writing
to the IPO Conversion).

          (c) The parties hereto agree that the steps taken to develop and implement the IPO Conversion
shall not require the Minority Member or its Permitted Transferees to convert their LLC Units to,
or cause them, solely as a result of holding such LLC Units, to hold indirectly, equity interests
in an entity that is treated as a corporation for U.S. federal income tax purposes (other than any
immaterial Subsidiaries) as a condition to completion of the IPO Conversion or IPO, and if the IPO
Corporation is an entity treated as a corporation for U.S. federal income tax purposes, shall
provide such Members the right to so convert LLC Units to IPO Units from time to time following the
completion of such IPO, or provide for another IPO Conversion structure that is no less
advantageous from a federal income tax perspective to the Minority Member.

          (d) The Minority Member or its Permitted Transferee shall have the option in connection with
or at any time following an IPO Conversion in accordance with this Agreement, exercisable in each
case by providing at least ten Business Days’ prior written notice to the Company and the IPO
Corporation (the “Option Notice”), either:

     (i) to transfer all or a portion of its LLC Units to the IPO Corporation in
exchange for payment to the Minority Member or its Permitted Transferee of such
number of equity securities of the IPO Corporation that represent the same economic
interest as the Member or its Permitted Transferee had with respect to the LLC Units
or IPO Units so transferred immediately prior to such transfer; or

     (ii) to permit the shareholders (the “Indirect Shareholders”) of the
member(s) of the Minority Member or its Permitted Transferee (collectively, the
“Minority Member Parent”) to transfer all (but not less than all) of the
outstanding equity interests in the Minority Member Parent, and indebtedness of the
Minority Member Parent, if any, held by, or owed to, the Indirect Shareholders, as
of the date of such transfer (the “Transferred Debt”), to the IPO
Corporation (the “Equity and Debt Transfer”), pursuant to documentation
reasonably acceptable to the Minority Member or its Permitted Transferee, the
Indirect Shareholders and the IPO Corporation, in exchange for payment to the
Indirect Shareholders of (x) $1,000 in cash, and (y) such number of equity
securities of the IPO Corporation that have the same economic interest as the
Minority Member and its Permitted Transferee had with respect to its LLC Units in
the Company immediately prior to the Equity and Debt Transfer; provided,
that the Indirect Shareholders shall have the option to receive additional equity
securities of the IPO Corporation worth $1,000 in lieu of the cash payment described
in clause (x) above, upon so indicating in the Option Notice; and provided
further, that any Equity and Debt Transfer shall be subject to the following
conditions and requirements at the time of such Equity and Debt Transfer (except as
expressly provided below):

     (A)   neither the Minority Member Parent nor the Minority Member (or
any Permitted Transferee, to the extent applicable) shall have any assets
other than (w) the equity interests in the Minority Member (or

21

 

Permitted Transferee(s), if applicable) owned by the Minority Member
Parent, (x) LLC Units owned of record by the Minority Member (and/or its
Permitted Transferee(s), if applicable), (y) any distributions received in
respect of such LLC Units pursuant to the LLC Agreement and not yet further
distributed, and (z) any payments received pursuant to this Agreement and/or
the Tax Sharing Agreement and not yet further distributed. All such LLC
Units and equity interests in the Minority Member (or Permitted
Transferee(s), if applicable) described above shall, at the time of the
Equity and Debt Transfer, be free and clear of all Liens (as defined in the
Contribution and Subscription Agreement), other than those imposed by this
Agreement or the LLC Agreement;

     (B)   neither the Minority Member Parent nor the Minority Member (or
any Permitted Transferee, to the extent applicable) shall have any
obligations, commitments or liabilities (in each case whether or not
accrued, contingent, known or otherwise) other than (w) tax liabilities
solely resulting from the ownership by the Minority Member (and/or its
Permitted Transferee(s), if applicable) of LLC Units, including as a result
of distributions received or the allocation of income to the Minority Member
(and/or such Permitted Transferee(s)), and payments received by the Minority
Member under this Agreement and the Tax Sharing Agreement, in each case,
solely for the taxable period of Minority Member (and/or its Permitted
Transferee(s), if applicable) in which the date of the Equity and Debt
Transfer occurs, (x) customary liabilities directly related to the Minority
Member Parent’s existence as a corporation or the Minority Member’s
existence as a limited liability company, (y) liabilities owed by the
Minority Member Parent to the Indirect Shareholders under the Transferred
Debt, all of which are transferred to the IPO Corporation in connection with
the Equity and Debt Transfer, and (z) any other obligations, commitments or
liabilities that are immaterial in the aggregate; provided that the
Transferred Debt is fully prepayable at the time of the Equity and Debt
Transfer or thereafter without penalty, premium or make whole;

     (C)   neither the Minority Member Parent nor the Minority Member (or
any Permitted Transferee, to the extent applicable) is a party to or
otherwise bound by (nor are any of their respective assets or properties
bound by) any contractual or similar obligation whatsoever (including, for
the avoidance of doubt, any obligation to set aside, issue or grant any
equity interests to any Person), other than those directly imposed pursuant
to this Agreement, the LLC Agreement, the Registration Rights Agreement, the
Tax Sharing Agreement and the agreements governing the Transferred Debt,
copies of which shall have been provided to the IPO Corporation prior to the
Equity and Debt Transfer;

     (D)   in connection with and as a condition to any such Equity and Debt
Transfer, the Indirect Shareholders jointly and severally agree to

22

 

indemnify, defend and hold harmless the IPO Corporation, the Initial
Member and their respective Affiliates and representatives from and against
any obligations, commitments or liabilities (in each case whether or not
accrued, contingent, known or otherwise) whatsoever (including any
liabilities for Taxes) of the Minority Member Parent, the Minority Member
and, if applicable, its Permitted Transferees, and in the case of (B) below,
any such liabilities imposed on the IPO Corporation (A) in respect of
periods or portions of periods ending on or prior to the Equity and Debt
Transfer (whether arising before, on or after the date of the Equity and
Debt Transfer, and including any successor or transferee liabilities, by
contract or otherwise, and including the portion of any Straddle Period that
ends on the date of the Equity and Debt Transfer), other than the
liabilities of Minority Member Parent for the Transferred Debt (subject to
clause (B) immediately following), and (B) incurred by virtue of the
cancellation, termination, contribution to capital or other extinguishment
of the Transferred Debt (including any Taxes imposed on any cancellation of
indebtedness income realized by Minority Member Parent, as a result of such
cancellation, termination, contribution to capital or other extinguishment),
provided, that the maximum amount payable under this clause (B)
shall not exceed the greater of (i) any liabilities for Taxes arising solely
from the Equity and Debt Transfer and an immediately following contribution
of the Transferred Debt to the capital of the Minority Member Parent or (ii)
any liabilities for Taxes arising solely from the Equity and Debt Transfer
and a liquidation of the Minority Member Parent pursuant to a plan of
liquidation adopted on or after the Equity and Debt Transfer and completed
within 10 days following the Equity and Debt Transfer, provided further that
if the IPO Corporation takes the actions described in clause (i) or (ii)
with respect to the Transferred Debt, such maximum amount shall not exceed
the liabilities for Taxes described in the applicable clause;

     (E)   to the extent requested by the IPO Corporation, the Indirect
Shareholders shall provide the IPO Corporation, prior to the Equity and Debt
Transfer, with resignation letters, effective as of the Equity and Debt
Transfer, from each of the directors, officers, general partners, managing
members, or other Persons serving in a similar capacity of each of the
Minority Member Parent, Minority Member and, to the extent applicable, the
Permitted Transferees of the Minority Member;

     (F)   the Indirect Shareholders shall provide the IPO Corporation,
prior to the Equity and Debt Transfer, with all corporate and organizational
documents, documents relating to indebtedness, debt or equity securities,
tax returns (including information returns and any documentation relating to
the withholding of taxes on any distributions or interest payments made by
Minority Member or Minority Member Parent, including any IRS certifications
provided by the Indirect Shareholders) and all historical and current tax
and accounting work papers (to the extent

23

 

provided to the Minority Member Parent or their representatives) with
respect to periods for which the applicable statute of limitations remains
open as of the time of such Equity and Debt Transfer and, to the extent
reasonably requested by the IPO Corporation, any other books and records or
tax information, of each of the Minority Member Parent, Minority Member and,
to the extent applicable, the Permitted Transferees of the Minority Member;

     (G)   in the event that any of the Indirect Shareholders is not, in the
IPO Corporation’s reasonable judgment, a well-capitalized creditworthy
entity with readily available cash resources to satisfy indemnification
obligations under clause (D) above, each such Indirect Shareholder shall
provide an irrevocable guarantee of performance and payment under this
Section 3.7(d)(ii) from an entity reasonably acceptable to the IPO
Corporation, or other credit support of such obligations that is reasonably
acceptable to the IPO Corporation; and

     (H)   a duly authorized representative of each of the Indirect
Shareholders shall provide an Officer’s Certificate to the IPO Corporation
(in form and substance reasonably satisfactory to the IPO Corporation) prior
to the Equity and Debt Transfer certifying as to satisfaction with the
requirements set forth in clauses (A) through (G) above, including
affirmation of the indemnification obligations under clause (D) above.

For greater certainty, it shall be within the Minority Member’s or its Permitted Transferee’s sole
discretion whether to exercise any option contained in this Section 3.7(d) and the Minority Member
or its Permitted Transferee shall be permitted to remain a member of the Company or its successor
or any Person to which all or substantially all of the assets of the Company are transferred until
exercising such option.

          Section 3.8. Specific Performance

          Each of the parties to this Agreement acknowledges that it shall be impossible to measure in
money damages to the Company or the Member(s), if any of them or any transferee or any legal
representative of any party hereto fails to comply with any of the restrictions or obligations
imposed by this Article III, that every such restriction or obligation is material, and that in the
event of any such failure, neither the Company nor the Member(s) shall have an adequate remedy at
law or in damages. Therefore, each party hereto consents to, in addition to any other remedies
that may be available, the issuance of an injunction or the enforcement of other equitable
remedies against it at the suit of an aggrieved party without the posting of any bond or other
equity security or proving actual damages, to compel specific performance of all of the terms of
this Article III and to prevent any Transfer of LLC Units in contravention of any terms of this
Article III, and waives any defenses thereto, including the defenses of: (i) failure of
consideration; (ii) breach of any other provision of this Agreement; and (iii) availability of
relief in damages.

24

 

          Section 3.9. Right of First Refusal

          (a) Notwithstanding anything to the contrary contained herein but subject to Section 3.9(h),
prior to a Qualified IPO, the Minority Member and its Permitted Transferees (each a “Selling
Member”) shall not Transfer their LLC Units pursuant to Section 3.1(a)(iv)(B)(2) unless such
Selling Members have first complied with this Section 3.9.

          (b) In the event that a Selling Member intends to Transfer LLC Units or IPO Units, as the case
may be, such Selling Member shall deliver to EFH, so long as it has an indirect interest in the
Company and thereafter Parent (the “ROFR Party”) written notice of its intention to
Transfer LLC Units or IPO Units, as the case may be, (the “Notice of Intention to Sell”)
and the terms and conditions of the proposed Transfer, which notice shall state (i) the number of
LLC Units or IPO Units, as the case may be, to be Transferred (the “Offered Units”), (ii)
the purchase price therefor, including a description of any non-cash consideration sufficiently
detailed to permit valuation thereof, (iii) the identity of the proposed Transferee and (iv) any
other material terms and conditions of the proposed Transfer, including the proposed Transfer date
(which date may not be less than twenty (20) days after delivery of the Notice of Intention to
Sell). The Notice of Intention to Sell shall be accompanied by a written offer (the “Inside
Offer”) irrevocable for ten (10) Business Days from its receipt to sell or otherwise Transfer
to the ROFR Party or its designee, for a price in cash determined in accordance with Section
3.9(e), all, but not less than all, of the Offered Units, on the same terms and conditions as set
forth in the Notice of Intention to Sell.

          (c) If the ROFR Party chooses to exercise its rights hereunder (or have a designee exercise
such rights) and accept the Inside Offer, it shall give written notice to the Selling Member and to
the Company stating that the ROFR Party or its designee, as applicable (the “ROFR
Purchaser”) desires to purchase all of the Offered Units and shall specify a date of closing,
which date shall not be later than thirty (30) days after the receipt of such notice by the Selling
Member; provided, that such date of closing shall be extended to the extent necessary to
obtain any required regulatory approvals (but in no event shall such date be greater than 180 days
after the date specified in such notice to the Selling Member and the Company). If the ROFR Party
does not give such written notice within the ten (10) Business Day period specified in Section
3.9(b), the ROFR Party (and any applicable designee) shall be deemed to have waived all of its
rights under this Section 3.9 with respect to the proposed Transfer of LLC Units or IPO Units.

          (d) If the ROFR Party does not accept the Inside Offer (on its own behalf or on behalf of a
designee) or is deemed to have waived its rights pursuant to Section 3.9(c) or payment for the
Offered Units is not made by the ROFR Purchaser in accordance with Sections 3.9(e) and 3.9(f)
hereof, the Selling Member may Transfer such Offered Units to the bona fide third-party purchaser
identified in the Notice of Intention to Sell, during the sixty (60) day period immediately
following the later of expiration of the Inside Offer and, if the ROFR Party (whether on its own
behalf or that of a designee) duly accepted the Inside Offer, the time of payment for the Offered
Units. Any Offered Units not purchased pursuant to the Inside Offer or by such third-party
purchaser within the time periods specified herein shall again become subject to all of the terms
and conditions of this Section 3.9 and may not thereafter be Transferred except in accordance
therewith.

25

 

          (e) The purchase price applicable to the ROFR Purchaser for the Offered Units shall be an
amount equal to 100% of the cash purchase price and 100% of the Fair Market Value of any non-cash
consideration on a per unit basis set forth in the Notice of Intention to Sell. Notwithstanding
anything to the contrary in this Section 3.9, the time periods applicable to the election by the
ROFR Party to purchase (or allow its designee to purchase) the Offered Units set forth in clause
(b) of this Section 3.9 shall not be deemed to commence until a determination of Fair Market Value
of any non-cash consideration pursuant to the definition thereof has been made.

          (f) If the ROFR Party (whether on its own behalf or that of a designee) chooses to exercise
its right to purchase (or allow its designee to purchase) all of the Offered Units, the ROFR
Purchaser will purchase such Offered Units on substantially the same terms and with the same method
of payment as is specified in the Notice of Intention to Sell; provided, however,
that if the method or payment set forth in the Notice of Intention to Sell consists of property
other than cash, then the ROFR Purchaser shall be entitled to pay the purchase price in a sum of
cash as determined in accordance with Section 3.9(e).

          (g) At the closing of the purchase, the ROFR Purchaser shall make payment as described in
Section 3.9(f) against delivery by the Selling Member of the LLC Units or IPO Units, as the case
may be, and in the event that the LLC Units or IPO Units, as the case may be, are certificated,

ROFR Purchaser may reasonably require waivers of any tax liens or other liens or encumbrances,
representations and warranties or evidence of good title to the LLC Units or IPO Units, as the case
may be, to be sold, or evidence of the authority of any legal representatives, before tendering
payment for the LLC Units or IPO Units, as the case may be, to be purchased.

          (h) Notwithstanding anything herein to the contrary, but subject to Section 3.4, in
circumstances where (x) the ROFR Party (whether on its own behalf or that of a designee) chooses to
exercise its right to purchase (or allow its designee to purchase) all of the Offered Units
pursuant to this Section 3.9; and (y) the terms and conditions of the proposed Transfer pursuant to
Section 3.1(a)(iv)(B)(2), as described in the Notice of Intention to Sell, involve the Transfer of
all of the membership interests in or equity securities of the Selling Member or any of its
Affiliates and/or shareholder debt owed to such Affiliates or their direct or indirect
securityholders (collectively, the “ROFR Transferred Interests”) in lieu of the Transfer by
the Selling Member of LLC Units or IPO Units, as the case may be, then the Selling Member shall
have the option, in lieu of Transferring such LLC Units or IPO Units, as the case may be, to the
ROFR Purchaser, to instead offer to sell to the ROFR Party and its designees the ROFR Transferred
Interests on the same terms and conditions as set forth in the Notice of Intention to Sell,
including for greater certainty with respect to the purchase price and any rights of
indemnification; provided that in addition to any such terms, such offer shall also include
for the benefit of the ROFR Purchaser protections no less favorable than those described in each of
clauses (A) through (H) of Section 3.7(d)(ii). If the Selling Member intends to exercise its
option contained in this Section 3.9(h), it shall notify the ROFR Party of such intention in the

	 	(iii)	 	if to any other Member, to such Member at the
address or facsimile number provided by such Member and set forth on
the counterpart to the signature page hereto executed by such Member.

     Any such notice shall, if delivered personally, be deemed received upon delivery; shall, if
delivered by telecopy, be deemed received on the first Business Day following confirmation; shall,
if delivered by nationally recognized overnight delivery service, be deemed received the first
Business Day after being sent; and shall, if delivered by mail, be deemed received upon the earlier
of actual receipt thereof or five Business Days after the date of deposit in the United States
mail.

          (a) Whenever any notice is required to be given by Law or this Agreement, a written waiver
thereof, signed by the Person entitled to notice, whether before or after the time stated therein,
shall be deemed equivalent to the giving of such notice.

          Section 5.2. Entire Agreement; Supersede. This Agreement together with the LLC
Agreement, the Registration Rights Agreement, the Tax Sharing Agreement and the Contribution and
Subscription Agreement, constitute the entire agreement of the Company and the Members in their
capacity as members of the Company and their Affiliates relating to the subject matter contained
herein and supersedes all prior Contracts or agreements with respect thereto, whether oral or
written.

          Section 5.3. Effect of Waiver or Consent. A waiver or consent, express or implied, to
or of any breach or default by any Person in the performance by that Person of its obligations
hereunder is not a consent or waiver to or of any other breach or default in the performance by
that Person of the same or any other obligations of that Person hereunder. Failure on the part of
a Person to complain of any act of any Person or to declare any Person in default with respect to
their obligations hereunder, irrespective of how long that failure continues, does not constitute a
waiver by that Person of its rights with respect to that default until the applicable
statute-of-limitations period has run.

          Section 5.4. Amendment or Restatement. This Agreement (including any Exhibit or
Schedule hereto) may not be amended, modified, supplemented or restated, and no

29

 

provision of this Agreement may be waived other than by a written instrument adopted, executed
and agreed to by the Initial Member and the Minority Member, so long as the Minority Member or its
Permitted Transferees holds in excess of 1% of the then aggregate outstanding LLC Units.

          Section 5.5. Binding Effect; Third Party Beneficiaries. Subject to the restrictions
on Transfers set forth in this Agreement, this Agreement shall be binding upon and shall inure to
the benefit of the Company and each Member and each of their respective heirs, permitted
successors, permitted assigns, permitted distributees, Permitted Transferees and legal
representatives; and by their signatures hereto, the Company and each Member intend to and do
hereby become bound. Nothing expressed or mentioned in this Agreement is intended or shall be
construed to give any Person other than the parties hereto and their respective permitted
successors and assigns any legal or equitable right, remedy or claim under, in or in respect of
this Agreement or any provision herein contained (except in Sections 3.2(d), 3.3(e), 3.7 and 3.9).

          Section 5.6. Governing Law; Severability; Limitation of Liability

          (a) This Agreement shall be governed by and construed in accordance with the Laws of the State
of New York without giving effect to any otherwise governing principles of conflicts of law.

          (b) In the event of a direct conflict between the provisions of this Agreement and any
mandatory, non-waivable provision of the Act, such provision of the Act shall control. If any
provision of the Act provides that it may be varied or superseded by agreement of the members of a
limited liability company, such provision shall be deemed superseded and waived in its entirety if
this Agreement contains a provision addressing the same issue or subject matter.

          (c) If any provision of this Agreement is held to be illegal, invalid or unenforceable under
present or future Laws effective during the term of this Agreement, such provision shall be fully
severable; this Agreement shall be construed and enforced as if such illegal, invalid, or
unenforceable provision had never comprised a part of this Agreement; and the remaining provisions
of this Agreement shall remain in full force and effect and shall not be affected by the illegal,
invalid or unenforceable provision or by its severance from this Agreement. Furthermore, in lieu
of each such illegal, invalid or unenforceable provision, there shall be added automatically as a
part of this Agreement a provision as similar in terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

          (d) To the fullest extent permitted by Law, neither the Company nor any Member shall be liable
to any of the other such Persons for punitive, special, exemplary or consequential damages,
including damages for loss of profits, loss of use or revenue or losses by reason of cost of
capital, arising out of or relating to this Agreement or the transactions contemplated hereby,
regardless of whether based on Contract, tort (including negligence), strict liability, violation
of any applicable deceptive trade practices act or similar Law or any other legal or equitable
principle, and the Company and each Member releases each of the other such Persons from liability
for any such damages.

30

 

          (e) Each of the Members and the Company agree that irreparable damage would occur in the event
that any of the provisions of this Agreement were not performed in accordance with their specific
terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to
an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the
terms and provisions of this Agreement, this being in addition to any other remedy to which they
are entitled at law or in equity.

          Section 5.7. Further Assurances. In connection with this Agreement and the
transactions contemplated hereby, the Company and each Member shall execute and deliver all such
future instruments and take such other and further action as may be reasonably necessary or
appropriate to carry out the provisions of this Agreement and the intention of the parties as
expressed herein.

          Section 5.8. Counterparts. This Agreement may be executed in any number of
counterparts (including facsimile counterparts), all of which together shall constitute a single
instrument. It shall not be necessary that any counterpart be signed by the Company and each of
the Members so long as each counterpart shall be signed by one or more of the Members and so long
as the other Members shall sign at least one counterpart which shall be delivered to the Company
(and the Company shall sign at least one counterpart).

          Section 5.9. Other Covenants. Each Member entitled to vote on matters submitted to a
vote of the members of the Company, if any, agrees to vote the LLC Units owned by such Member upon
all matters arising under this Agreement submitted to a vote of the members of the Company, as the
case may be, in a manner that will implement the terms of this Agreement.

          Section 5.10. Aggregation of Units. All LLC Units held or acquired by a Member and
its Affiliates shall be aggregated together for purposes of determining the rights or obligations
of a Member, or application of any restrictions to a Member, or reference to its LLC Units under
this Agreement, in each instance in which such right, obligation or restriction is determined by
any ownership threshold.

          Section 5.11. Judicial Proceedings. In any judicial proceeding involving any dispute,
controversy or claim arising out of or relating to this Agreement or the Company or its operations,
each of the Members and the Company unconditionally agrees to (i) irrevocably submit to the
non-exclusive jurisdiction of the United States District Court for the Southern District of New
York and any state court sitting in the City of New York, Borough of Manhattan (the “Chosen
Courts”), (ii) waive any objection to laying venue in any such action or proceeding in the
Chosen Courts and (iii) waive any objection that the Chosen Courts are an inconvenient forum or do
not have jurisdiction over any party hereto. In any such judicial proceeding, the Members agree
that in addition to any method for the service of process permitted or required by such courts, to
the fullest extent permitted by Law, service of process may be made by delivery provided pursuant
to the directions in Section 5.1. EACH OF THE MEMBERS HEREBY WAIVES TRIAL BY JURY IN ANY JUDICIAL
PROCEEDING INVOLVING ANY DISPUTE, CONTROVERSY OR CLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT
OR RELATING TO THE COMPANY OR ITS OPERATIONS.

notice or other action to, with or by any Governmental Authority or any other Person, is

SCHEDULE
3.3(D)

Investor Rights Agreement Principles

The amended LLC Agreement and the amended Investor Rights Agreement would reflect terms typical and
customary for investors in a business holding similar proportions of ownership interests as the
Members and would include the following principles:

	1.	 	Board Representation
	 
	 	 	Prior to falling below an ownership threshold to be agreed by the parties, each Member shall
have the right to appoint directors to the Board of Directors of the Company in proportion
to its ownership interest in the Company.
	 
	2.	 	Decisions Requiring Minority Member Approval
	 
	 	 	Decisions of the Board of Directors and the Members shall generally be made by a simple
majority vote. Notwithstanding the foregoing, prior to the Minority Member falling below an
ownership threshold to be agreed by the parties, certain decisions require the approval of
the directors elected by the Minority Member (in the case of a decision made by the Board of
Directors) or the Minority Member itself (in the case of a decision made by the Members).
Subject to appropriate exceptions and further details to be negotiated, those decisions
would include:

	 	•	 	amending the constitutional documents of the Company or any of its material
subsidiaries (including the amended LLC Agreement);
	 
	 	•	 	issuing additional equity interests of the Company (including, without limitation,
options over equity securities and securities convertible into shares);
	 
	 	•	 	converting, exchanging, reclassifying, redesignating, subdividing or amending any
securities of the Company or any of its material subsidiaries or amending the rights,
privileges, restrictions and conditions attaching to any securities of the Company or
any of its material subsidiaries;
	 
	 	•	 	issuing, entering into or assuming any material new debt securities or credit
facilities or similar indebtedness (other than refinancing any debt existing prior to
the date of the applicable Required Sale that does not materially increase outstanding
amounts and in any event excluding borrowings and reborrowings under revolving credit
and similar facilities), including by way of the provision of any guarantees or
indemnities by the Company or any of its subsidiaries;
	 
	 	•	 	for so long as the Company’s credit rating is investment grade, raising any
non-investment grade debt;
	 
	 	•	 	making any material repayments of principal in addition to scheduled or other
mandatory principal payments on any debt that may be owing by the Company or any of its
subsidiaries;

1

 

	 	•	 	approval of material individual capital expenditures that are not expressly
contemplated in the annual capital budget and not necessary to address emergency
situations or legal requirements;
	 
	 	•	 	approval of material expenditures that are not expressly contemplated in the annual
budget of the Company and not necessary to address emergency situations or legal
requirements;
	 
	 	•	 	approval of commencement or settlement of any material litigation;
	 
	 	•	 	amending material employee benefit arrangements for senior executives in any
material respect;
	 
	 	•	 	entering into any transaction (including by way of merger or plan of arrangement)
involving a material acquisition or disposition of assets or shares;
	 
	 	•	 	entering into joint ventures, partnerships or similar arrangements;
	 
	 	•	 	approval of material changes in accounting policy;
	 
	 	•	 	appointment, removal or replacement of auditors if they are not one of the top 4
nationally recognized accounting firms;
	 
	 	•	 	approval of the annual budget of the Company and the business plan of the Company;
	 
	 	•	 	approval of any change in the tax status of the Company or any of its subsidiaries;
	 
	 	•	 	approving a proposal to effect a reorganization, liquidation, dissolution or winding
up of the Company or any of its material subsidiaries;
	 
	 	•	 	voluntarily assigning the Company or any of its subsidiaries into bankruptcy or
making of a proposal for the benefit of its creditors;
	 
	 	•	 	making a material change in the nature of the business carried on by the Company or
any of its subsidiaries or in the discontinuance or termination of the business of the
Company or any of its subsidiaries;
	 
	 	•	 	appointment, removal and replacement of the Chief Executive Officer and the Chief
Financial Officer of the Company;
	 
	 	•	 	any proposed change in the distribution policy agreed to by the Members in respect
of the Company;
	 
	 	•	 	any related party transaction; and
	 
	 	•	 	initiating any rate case and approval of submission(s) in connection with any rate
case.

2

 

	3.	 	Dispositions of Interests
	 
	 	 	Dispositions of each Member’s interests in the Company shall be subject to a right of first
offer which will provide that, to the extent that a Member (the “Selling Party”) determines
to sell directly or indirectly some or all of its interests in the Company (the “Sale
Interests”) to a third party (a “Disposition”), the Selling Party shall first offer the Sale
Interests to the other Members, who shall be entitled to purchase the Sale Interests at the
price (the “Sale Price”) at which the Selling Party reasonably determines to offer the Sale
Interests to a third party pursuant to the Disposition; provided that if the other Members
determine not to acquire such Sale Interests at the Sale Price, the Selling Party shall have
a reasonable period of time to seek to sell such Sale Interests to a third party at a price
at or above the Sale Price.
	 
	 	 	In addition to the right of first offer described above, dispositions of each Member’s
interests in the Company shall be subject to tag-along rights in the form provided in the
Investor Rights Agreement and drag-along rights in the form provided in the Investor Rights
Agreement except that the exercise of such drag-along rights will only be triggered in
connection with a determination by 90% or more in interest of the Members.
	 
	4.	 	Transfer Restrictions
	 
	 	 	No restrictions on transfer of interests in the Company, except as set forth above.

terms of this Agreement, under and in accordance with the provisions of the Securities Act, the
number of Registrable Securities requested to be so registered by the Initial Member or the
Minority Member pursuant to the terms of this Agreement, (any such written notice pursuant to
clause (i) or (ii), a “Demand Notice” and any such registration, a “Demand
Registration”); provided, however, that, in each case, a Demand Notice may only
be made if the Registrable Securities requested to be registered in such Demand Notice is
reasonably expected by such demanding Shareholder to result in aggregate gross cash proceeds in
excess of $200,000,000 (without regard to any underwriting discount or commission);
provided, further that, unless the Initial Member shall otherwise consent, the
Company shall not be obligated to file a Registration Statement relating to any registration
request under this Section 3(a) within a period of 180 days after the effective date of any other
Registration Statement relating to any registration request under this Section 3(a) (except if the
underwriters shall require a longer period, but in any event no more than 270 days). Following
receipt of a Demand Notice for a Demand Registration in accordance with this Section 3(a), the
Company shall use its reasonable best efforts to file a Registration Statement as promptly as
practicable and shall use its reasonable best efforts to cause such Registration Statement to be
declared effective under the Securities Act as promptly as practicable after the filing thereof;
provided, however, that notwithstanding the foregoing, if a Demand Notice is
delivered or caused to be delivered by the Minority Member pursuant to its right to make an IPO
Demand under Section 3(a)(i), such notice shall be deemed to have been delivered on the date that
is 120 days after the date that such notice is delivered by the Minority Member. During the 120
day period set forth in the immediately preceding sentence of this Section 3(a), the Company shall
consult with the Initial Member and, if directed by the Initial Member, the Company shall prepare
an Alternative IPO Entity for the initial Public Offering in accordance with Section 11
hereof and any demand made by the Minority Member shall thereafter be deemed to be a Demand
Notice in respect of the IPO Units; provided that, prior to the date that is ten years after the
date hereof, no Member (other than the Initial Member) shall be entitled to serve a Demand

4

 

Notice
in respect of the LLC Units or the IPO Units until the date that is 30 days after the final day of
any lock-up period relating to the IPO agreed between the Alternative IPO Entity and the
underwriters managing the IPO of the Alternative IPO Entity.

          No Demand Registration or related Demand Notice shall be deemed to have occurred for purposes
of this Section 3 if the Registration Statement relating thereto (i) does not become effective,
(ii) is not maintained effective for the period required pursuant to this Section 3, or (iii) the
offering of the Registrable Securities pursuant to such Registration Statement is subject to a stop
order, injunction, or similar order or requirement of the SEC during such period, in which case,
such requesting holder of Registrable Securities shall be entitled to an additional Demand Notice
and Demand Registration in lieu thereof.

          Within 10 days after receipt by the Company of an IPO Demand in accordance with clause (i) of
the first paragraph of this Section 3(a), provided that the Member serving the IPO Demand proposes
to include Registrable Securities held by such Member in the offering that is the subject of such
IPO Demand, or a Demand Notice in accordance with clause (ii) of the first paragraph of this
Section 3(a), the Company shall give written notice (the “Participation Notice”) of such
IPO Demand or Demand Notice to all other Shareholders directly or indirectly holding Registrable
Securities and shall, subject to the provisions of Section 3(b) hereof, offer to such Shareholders
the opportunity to include in such registration all Registrable Securities with respect to which
the Company received written requests for inclusion therein within 15 days after such Participation
Notice is given by the Company to such holders.

          All requests made pursuant to this Section 3 will specify the number of Registrable Securities
to be registered and/or, in the case of an initial Public Offering, the number of LLC Units to be
issued or sold, and the intended methods of disposition thereof.

          The Company shall be required to maintain the effectiveness of the Registration Statement with
respect to any Demand Registration for a period of at least 180 days (two years for a shelf
registration statement) after the effective date thereof or such shorter period during which all
Registrable Securities included in such Registration Statement have actually been sold;
provided, however, that such period shall be extended for a period of time equal to
the period the holder of Registrable Securities refrains from selling any securities included in
such Registration Statement at the request of the Company or an underwriter of the Company pursuant
to the provisions of this Agreement.

               (b) Priority on Demand Registration. If any of the Registrable Securities registered
pursuant to a Demand Registration are to be sold in a firm commitment underwritten offering, and
the managing underwriter or underwriters advise the holders of such securities in writing that in
its view the total number or dollar amount of Registrable Securities proposed to be sold in such
offering is such as to adversely affect the success of such offering (including, without
limitation, securities proposed to be included by other holders of securities entitled to include
securities in such Registration Statement pursuant to incidental or piggyback registration rights),
then there shall be included in such firm commitment underwritten offering
the number or dollar amount of Registrable Securities that in the opinion of such managing
underwriter can be sold without adversely affecting such offering, and such number of

5

 

Registrable
Securities shall be allocated as follows, unless the underwriter requires a different allocation as
between the Company and the selling holders:

     (i) first, among the holders of Registrable Securities included in such
Registration Statement who had delivered the applicable Demand Notice, pro rata
among them on the basis of the relative number of shares of Registrable Securities
requested to be included in such Registration Statement by each such demanding
holder; and

     (ii) second, among the Company for LLC Units it has requested to include in
such Demand Registration for its own account and any other Shareholders duly
requesting inclusion of Registrable Securities in accordance with a Participation
Notice, pro rata among them on the basis of the relative number of LLC Units
requested to be included in such Registration Statement by each.

          For purposes of any underwriter cutback, all Registrable Securities held by any Shareholder
shall also include any Registrable Securities held by the partners, retired partners, shareholders
or affiliates of such holder, or the estates and family members of any such holder or such partners
and retired partners, any trusts for the benefit of any of the foregoing persons and, at the
election of such holder or such partners, retired partners, trust or affiliates, any charitable
organization, in each case to which any of the foregoing shall have been distributed, transferred
or contributed Registrable Securities prior to the execution of the underwriting agreement in
connection with such underwritten offering; provided, that such distribution, transfer or
contribution occurred not more than 90 days prior to such execution, and such holder and other
persons shall be deemed to be a single selling Shareholder, and any pro rata reduction (unless the
managing underwriter requires a different allocation as between the Company and the selling
holders) with respect to all entities and individuals comprising such single selling Shareholder as
amongst themselves shall be based upon the proportionate ownership of Registrable Securities of
each entity and individual included in such single selling Shareholder relative to the aggregate
amount of Registrable Securities owned by all entities and individuals included in such single
selling Shareholder. No securities excluded from the underwriting by reason of the underwriter’s
marketing limitation shall be included in such registration.

               (c) Postponement of Demand Registration. The Company shall be entitled to postpone
(but not more than once in any 12-month period), for a reasonable period of time not in excess of
60 days, the filing of a Registration Statement if the Company delivers to the holders requesting
registration a certificate signed by the chief executive officer or chief financial officer of the
Company certifying that, in the good faith judgment of the board of directors of the Company, such
registration and offering would reasonably be expected to materially adversely affect or materially
interfere with any bona fide material financing of the Company or any material
transaction under consideration by the Company or would require disclosure of information that has
not been disclosed to the public, the premature disclosure of which would materially adversely
affect the Company. Such certificate shall contain a statement of the reasons for such
postponement and an approximation of the anticipated delay. The holders
receiving such certificate shall keep the information contained in such certificate
confidential subject to the same terms set forth in Section 6(p). If the Company shall so postpone
the filing of

6

 

a Registration Statement, the Shareholder requesting such registration shall have the
right to withdraw the request for registration by giving written notice to the Company within 20
days of the anticipated termination date of the postponement period, as provided in the certificate
delivered to the holders, and, for greater certainty, if the Shareholder that so withdraws such
request is the Minority Member, such request shall not be considered one of the Minority Member’s
two permitted Demand Notices pursuant to Section 3(e).

               (d) Cancellation of a Demand Registration. Holders of a majority of the Registrable
Securities which are to be registered in a particular offering pursuant to this Section 3 shall
have the right to notify the Company that they have determined that the Registration Statement be
abandoned or withdrawn, in which event the Company shall abandon or withdraw such Registration
Statement, and, for greater certainty, in such circumstances if the Shareholder that requested such
registration is the Minority Member, such request shall not be considered one of the Minority
Member’s two permitted Demand Notices pursuant to Section 3(e).

               (e) Number of Demand Notices. In connection with the provisions of this Section 3,
(i) the Initial Member shall have an unlimited number of Demand Notices which it is permitted to
deliver (or cause to be delivered) to the Company hereunder and (ii) the Minority Member shall have
two Demand Notices which it is permitted to deliver (or cause to be delivered) to the Company
hereunder.

               (f) Registration Statement Form. If any registration requested pursuant to this
Section 3 which is proposed by the Company to be effected by the filing of a Registration Statement
on Form S-3 (or any successor or similar short-form registration statement) shall be in connection
with an underwritten Public Offering, and if the managing underwriter shall advise the Company in
writing that, in its opinion, the use of another form of Registration Statement is of material
importance to the success of such proposed offering or is otherwise required by applicable law,
then such registration shall be effected on such other form.

     Section 4. Piggyback Registration.

               (a) Right to Piggyback. Except with respect to a Demand Registration or an initial
Public Offering, the procedures for which are addressed in Section 3, if the Company proposes to
file a registration statement under the Securities Act with respect to an offering of LLC Units
whether or not for sale of its own account (other than a registration statement (i) on Form S-4,
Form S-8 or any successor forms thereto or (ii) filed solely in connection with an exchange offer
or any employee benefit or dividend reinvestment plan), the Company shall give prompt written
notice of such proposed filing at least twenty (20) days before the anticipated filing date (the
“Piggyback Notice”) to all Shareholders holding Registrable Securities. The Piggyback
Notice shall offer such holders the opportunity to include (or cause to be included) in such
registration statement the number of Registrable Securities as each such holder may request (a
“Piggyback Registration”). Subject to Section 4(b) hereof, the Company shall include in
each such Piggyback Registration all Registrable Securities with respect to which the Company has
received written requests for inclusion therein within fifteen (15) days after notice has been
given to the applicable holder. The eligible holders of Registrable Securities shall be permitted
to withdraw all or part of the Registrable Securities from a Piggyback Registration at any time at

7

 

least three business days prior to the effective date of such Piggyback Registration. The Company
shall not be required to maintain the effectiveness of the Registration Statement for a Piggyback
Registration beyond the earlier to occur of (i) 180 days (two years for a shelf registration
statement) after the effective date thereof and (ii) all Registrable Securities included in such
Registration Statement have actually been sold.

               (b) Priority on Piggyback Registrations. The Company shall use reasonable best
efforts to cause the managing underwriter or underwriters of a proposed underwritten offering to
permit direct or indirect holders of Registrable Securities who have submitted a Piggyback Notice
in connection with such offering to include in such offering all Registrable Securities included in
each holder’s Piggyback Notice on the same terms and conditions as any other shares of capital
stock, if any, of the Company included in the offering. Notwithstanding the foregoing, if the
managing underwriter or underwriters of such underwritten offering have informed the Company in
writing that it is their good faith opinion that the total amount of securities that such holders,
the Company and any other Persons having rights to participate in such registration, intend to
include in such offering is such as to adversely affect the success of such offering, then the
amount of securities to be offered for the account of holders of Registrable Securities (other than
the Company) shall be reduced to the extent necessary to reduce the total amount of securities to
be included in such offering to the amount recommended by such managing underwriter or underwriters
by reducing the securities requested to be included by the holders of Registrable Securities
requesting such registration pro rata among such holders on the basis of the relative number of
shares of Registrable Securities requested to be included in such Registration Statement by each
such holder.

     Section 5. Restrictions on Public Sale by Holders of Registrable Securities. Each
Shareholder agrees, in connection with the initial Public Offering, and each holder of Registrable
Securities agrees, in connection with any other underwritten Public Offering pursuant to a
Registration Statement filed pursuant to Section 3 or Section 4 hereof (whether or not such holder
elected to include Registrable Securities in such Registration Statement), if requested (pursuant
to a written notice) by the managing underwriter or underwriters in an underwritten offering, not
to effect any public sale or distribution of any of the Company’s securities (except as part of
such underwritten offering), including a sale pursuant to Rule 144 or any swap or other economic
arrangement that transfers to another any of the economic consequences of owning the Registrable
Securities, or to give any Demand Notice during the period commencing on the date of the request
(which shall be no earlier than 14 days prior to the expected “pricing” of such offering) and
continuing for not more than 180 days (with respect to the initial Public Offering) or 90 days
after the date of the Prospectus (or Prospectus supplement if the offering is made pursuant to a
shelf registration statement), pursuant to which such Public Offering shall be made, plus an
extension period, which shall be no longer than 17 days, as may be proposed by the managing
underwriter to address FINRA regulations regarding the publishing of research, or such lesser
period as is required by the managing underwriter.

          If any registration pursuant to Section 3 of this Agreement shall be in connection with any
underwritten Public Offering, the Company will not effect any public sale or distribution of any
common equity (or securities convertible into or exchangeable or exercisable for common equity)
(other than a registration statement (i) on Form S-4, Form S-8 or any successor forms thereto or
(ii) filed solely in connection with an exchange offer or any employee

8

 

benefit or dividend
reinvestment plan) for its own account, within 90 days (or such shorter periods as the managing
underwriters may agree to with the Company) after the effective date of such registration, plus an
extension period, which shall be no longer than 17 days, as may be proposed by the managing
underwriter to address FINRA regulations regarding the publishing of research, or such lesser
period as is required by the managing underwriter.

     Section 6. Registration Procedures. If and whenever the Company is required to effect
the registration of any Registrable Securities under the Securities Act as provided in Section 3
and Section 4 hereof, the Company shall effect such registration 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 cooperate in the sale of the securities and shall, as
expeditiously as possible:

               (a) prepare and file with the SEC a Registration Statement or Registration Statements on such
form as shall be available for the sale of the Registrable Securities by the holders thereof or by
the Company in accordance with the intended method or methods of distribution thereof, and use its
reasonable best efforts to cause such Registration Statement to become effective and to remain
effective as provided herein (including by means of a shelf registration statement pursuant to Rule
415 under the Securities Act providing for an offering to be made on a continuous basis if so
requested and if the Company is then eligible to use Form S-3 or other applicable Form);
provided, however, that before filing a Registration Statement or Prospectus or any
amendments or supplements thereto (including documents that would be incorporated or deemed to be
incorporated therein by reference), the Company shall furnish or otherwise make available to the
holders of the Registrable Securities covered by such Registration Statement, their counsel and the
managing underwriters, if any, copies of all such documents proposed to be filed, which documents
will be subject to the reasonable review and comment of such counsel, and such other documents
reasonably requested by such counsel, including any comment letter from the SEC, and, if requested
by such counsel, provide such counsel reasonable opportunity to participate in the preparation of
such Registration Statement and each Prospectus included therein and such other opportunities to
conduct a reasonable investigation within the meaning of the Securities Act, including reasonable
access to the Company’s books and records, officers, accountants and other advisors. The Company
shall not file any such Registration Statement or Prospectus or any amendments or supplements
thereto (including such documents that, upon filing, would be incorporated or deemed to be
incorporated by reference therein) with respect to a Demand Registration to which the holders of a
majority of the Registrable Securities covered by such Registration Statement, their counsel, or
the managing underwriters, if any, shall reasonably object, in writing, on a timely basis, unless,
in the opinion of the Company, such filing is necessary to comply with applicable law;

               (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 during the period provided herein and comply in all material
respects with the provisions of the Securities Act with respect to the disposition of all
securities covered by such Registration Statement; and cause the related Prospectus to be
supplemented by any Prospectus supplement as may be necessary to comply with the provisions of the
Securities Act with respect to the disposition of the securities covered by such Registration
Statement, and

9

 

as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then
in force) under the Securities Act;

               (c) notify each selling holder of Registrable Securities, its counsel and the managing
underwriters, if any, promptly, and (if requested by any such Person) confirm such notice in
writing, (i) when a Prospectus or any Prospectus supplement or post-effective amendment thereto has
been filed, and, with respect to a Registration Statement or any post-effective amendment thereto,
when the same has become effective, (ii) of any request by the SEC or any other federal or state
governmental authority for amendments or supplements to a Registration Statement or related
Prospectus or for additional information, (iii) of the issuance by the SEC of any stop order
suspending the effectiveness of a Registration Statement or the initiation of any proceedings for
that purpose, (iv) if at any time the Company has reason to believe that the representations and
warranties of the Company contained in any agreement (including any underwriting agreement)
contemplated by Section 6(o) below cease to be true and correct, (v) of the receipt by the Company
of any notification with respect to the suspension of the qualification or exemption from
qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation
or threatening of any proceeding for such purpose, and (vi) if the Company has knowledge 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 the Registration Statement, 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, 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 necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading (which notice shall notify the selling holders only of
the occurrence of such an event and shall provide no additional information regarding such event to
the extent such information would constitute material non-public information);

               (d) use its reasonable best efforts to obtain the withdrawal of any order suspending the
effectiveness of a Registration Statement, or the lifting of any suspension of the qualification
(or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction
at the earliest date reasonably practicable;

               (e) if requested by the managing underwriters, if any, or the holders of a majority of the
then outstanding Registrable Securities being sold in connection with an underwritten offering,
promptly include in a Prospectus supplement or post-effective amendment such information as the
managing underwriters, if any, and such holders may reasonably request in order to permit the
intended method of distribution of such securities and make all required filings of such Prospectus
supplement or such post-effective amendment as soon as practicable after the Company has received
such request; provided, however, that the Company shall not be
required to take any actions under this Section 6(e) that are not, in the opinion of counsel
for the Company, in compliance with applicable law;

               (f) furnish or make available to each selling holder of Registrable Securities, its counsel
and each managing underwriter, if any, without charge, at least one

10

 

conformed copy of the
Registration Statement, the Prospectus and Prospectus supplements, if applicable, and each
post-effective amendment thereto, including financial statements (but excluding schedules, all
documents incorporated or deemed to be incorporated therein by reference, and all exhibits, unless
requested in writing by such holder, counsel or underwriter);

               (g) deliver to each selling holder of Registrable Securities, its counsel, 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 from time to time in connection with the distribution of the Registrable Securities; and
the Company, subject to the last paragraph of this Section 6, 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, if any, in connection with the offering and sale of the
Registrable Securities covered by such Prospectus and any such amendment or supplement thereto;

               (h) prior to any public offering of Registrable Securities, use its reasonable best efforts to
register or qualify or cooperate with the selling holders of Registrable Securities, the
underwriters, if any, 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 seller or underwriter reasonably requests in writing and to keep each such
registration or qualification (or exemption therefrom) effective during the period such
Registration Statement is required to be kept effective and to take any other action that may be
necessary or advisable to enable such holders of Registrable Securities to consummate the
disposition of such Registrable Securities in such jurisdiction; 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;

               (i) cooperate with the selling holders of Registrable Securities and the managing
underwriters, if any, to facilitate the timely preparation and delivery of certificates (not
bearing any legends) representing Registrable Securities to be sold after receiving written
representations from each holder of such Registrable Securities that the Registrable Securities
represented by the certificates so delivered by such holder will be transferred in accordance with
the Registration Statement, and enable such Registrable Securities to be in such denominations and
registered in such names as the managing underwriters, if any, or holders may request at least two
(2) business days prior to any sale of Registrable Securities in a firm commitment public offering,
but in any other such sale, within ten (10) business days prior to having to issue the securities;

               (j) use its reasonable best efforts to cause the Registrable Securities covered by the
Registration Statement to be registered with or approved by such other
governmental agencies or authorities within the United States, except as may be required
solely as a consequence of the nature of such selling holder’s business, in which case the Company
will cooperate in all reasonable respects with the filing of such Registration Statement and the
granting of such approvals, as may be necessary to enable the seller or sellers thereof or the
underwriters, if any, to consummate the disposition of such Registrable Securities;

11

 

               (k) upon the occurrence of, and its knowledge of, any event contemplated by Section 6(c)(vi)
above, 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;

               (l) prior to the effective date of the Registration Statement relating to the Registrable
Securities, provide a CUSIP number for the Registrable Securities;

               (m) provide and cause to be maintained a transfer agent and registrar for all Registrable
Securities covered by such Registration Statement from and after a date not later than the
effective date of such Registration Statement;

               (n) use its reasonable best efforts to cause all shares (i) to be offered by the Company in
connection with the initial Public Offering to be authorized to be listed on a national securities
exchange and (ii) of Registrable Securities covered by such Registration Statement to be listed on
a national securities exchange if shares of the particular class of Registrable Securities are at
that time listed on such exchange, as the case may be, prior to the effectiveness of such
Registration Statement (or, if such registration is the initial Public Offering, use its reasonable
best efforts to cause such Registrable Securities to be so listed within ten (10) business days
following the effectiveness of such Registration Statement);

               (o) enter into such agreements (including an underwriting agreement in form, scope and
substance as is customary in underwritten offerings) and take all such other actions reasonably
requested by the holders of a majority of the Registrable Securities being sold in connection
therewith (including those reasonably requested by the managing underwriters, if any) to expedite
or facilitate the disposition of such Registrable Securities, and in such connection, whether or
not an underwriting agreement is entered into and whether or not the registration is an
underwritten registration, (i) make such representations and warranties to the holders of such
Registrable Securities and the underwriters, if any, 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 customarily made by issuers to underwriters in underwritten offerings, and, if
true, confirm the same if and when requested, (ii) use its reasonable best efforts to furnish to
the selling holders of such Registrable Securities 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, if any, and counsels to the selling holders of the Registrable
Securities), addressed to each selling holder of Registrable Securities
and each of the underwriters, if any, covering the matters customarily covered in opinions
requested in underwritten offerings and such other matters as may be reasonably requested by such
counsel and underwriters, (iii) use its reasonable best efforts to obtain “cold comfort” letters
and updates thereof from the independent registered public accountants of the Company (and, if
necessary, any other independent registered public accountants of any subsidiary of the Company or
of any business acquired by the Company for which financial statements and

12

 

financial
data are, or
are required to be, included in the Registration Statement) who have certified the financial
statements included in such Registration Statement, addressed to each selling holder of Registrable
Securities (unless such accountants shall be prohibited from so addressing such letters by
applicable standards of the accounting profession) and each of the underwriters, if any, such
letters to be in customary form and covering matters of the type customarily covered in “cold
comfort” letters in connection with underwritten offerings, (iv) if an underwriting agreement is
entered into, the same shall contain indemnification provisions and procedures substantially to the
effect set forth in Section 8 hereof with respect to all parties to be indemnified pursuant to said
Section except as otherwise agreed by the holders of a majority of the Registrable Securities being
sold thereunder and (v) deliver such documents and certificates as may be reasonably requested by
the holders of a majority of the Registrable Securities being sold pursuant to such Registration
Statement, their counsel and the managing underwriters, if any, to evidence the continued validity
of the representations and warranties made pursuant to Section 6(o)(i) above and to evidence
compliance with any customary conditions contained in the underwriting agreement or other agreement
entered into by the Company. The above shall be done at each closing under such underwriting or
similar agreement, or as and to the extent required thereunder;

               (p) make available for inspection by a representative of the selling holders of Registrable
Securities, any underwriter participating in any such disposition of Registrable Securities, if
any, and any attorneys or accountants retained by such selling holders or underwriter, at the
offices where normally kept, during reasonable business hours, all financial and other records,
pertinent corporate documents and properties of the Company and its subsidiaries, and cause the
officers, directors and employees of the Company and its subsidiaries to supply all information in
each case reasonably requested by any such representative, underwriter, attorney or accountant in
connection with such Registration Statement; provided, however, that any
information that is not generally publicly available at the time of delivery of such information
shall be kept confidential by such Persons unless (i) disclosure of such information is required by
court or administrative order, (ii) disclosure of such information, in the opinion of counsel to
such Person, is required by law or applicable legal process, or (iii) such information becomes
generally available to the public other than as a result of a non-permitted disclosure or failure
to safeguard by such Person. In the case of a proposed disclosure pursuant to (i) or (ii) above,
such Person shall be required to give the Company written notice of the proposed disclosure prior
to such disclosure (to the extent permitted by law) and, if requested by the Company, assist the
Company in seeking to prevent or limit the proposed disclosure. Without limiting the foregoing, no
such information shall be used by such Person as the basis for any market transactions in
securities of the Company or its subsidiaries in violation of law;

               (q) cause its officers to use their reasonable best efforts to support the marketing of the
Registrable Securities covered by the Registration Statement (including,
without limitation, participation in “road shows”) taking into account the Company’s business
needs; and

               (r) cooperate with each seller of Registrable Securities and each underwriter or agent
participating in the disposition of such Registrable Securities and their respective counsel in
connection with any filings required to be made with FINRA.

13

 

          The Company may require each holder of Registrable Securities as to which any registration is
being effected to furnish to the Company in writing such information required in connection with
such registration regarding such seller and the distribution of such Registrable Securities as the
Company may, from time to time, reasonably request in writing and the Company may exclude from such
registration the Registrable Securities of any holder who unreasonably fails to furnish such
information within a reasonable time after receiving such request.

          Each holder of Registrable Securities agrees if such holder has Registrable Securities covered
by such Registration Statement that, upon receipt of any notice from the Company of the happening
of any event of the kind described in Section 6(c)(ii), 6(c)(iii), 6(c)(iv) or 6(c)(v) hereof, 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 6(k) hereof, 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
additional or supplemental filings that are incorporated or deemed to be incorporated by reference
in such Prospectus; provided, however, that the time periods under Section 3 with
respect to the length of time that the effectiveness of a Registration Statement must be maintained
shall automatically be extended by the amount of time the holder is required to discontinue
disposition of such securities.

     Section 7. Registration Expenses. All reasonable fees and expenses incident to the
performance of or compliance with this Agreement by the Company (including, without limitation, (i)
all registration and filing fees (including, without limitation, fees and expenses (A) with respect
to filings required to be made with FINRA and (B) of compliance with securities or Blue Sky laws,
including, without limitation, any fees and disbursements of counsel for the underwriters in
connection with Blue Sky qualifications of the Registrable Securities pursuant to Section 6(h)),
(ii) printing expenses (including, without limitation, expenses of printing certificates for
Registrable Securities in a form eligible for deposit with The Depository Trust Company and of

any, or by the holders of a majority of the Registrable Securities included in any Registration
Statement), (iii) messenger, telephone and delivery expenses of the Company, (iv) fees and
disbursements of counsel for the Company, (v) expenses of the Company incurred in connection with
any road show, (vi) fees and disbursements of all independent registered public accountants

retained by the Company, and (vii) fees and disbursements of one counsel for the holders of
Registrable Securities whose shares are included in a Registration Statement, which counsel shall
be selected by the Initial Member (provided the Initial Member is a selling holder, and otherwise,
by the holders of a majority of
the Registrable Securities being sold in connection therewith), shall be borne by the Company
whether or not any Registration Statement is filed or becomes effective. In addition, the Company
shall pay its internal expenses (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expense of any annual audit, the
fees and expenses incurred in connection with the listing of the securities to be registered on any
securities exchange on which similar securities issued by the Company are then listed and rating
agency fees and the fees and expenses of any Person, including special experts, retained by the
Company.

14

 

          The Company shall not be required to pay (i) fees and disbursements of any counsel retained by
any holder of Registrable Securities or by any underwriter (except as set forth in clauses 7(i)(B)
and 7(vii)), (ii) any underwriter’s fees (including discounts, commissions or fees of underwriters,
selling brokers, dealer managers or similar securities industry professionals) relating to the
distribution of the Registrable Securities (other than with respect to Registrable Securities sold
by the Company), or (iii) any other expenses of the holders of Registrable Securities not
specifically required to be paid by the Company pursuant to the first paragraph of this Section 7.

     Section 8. Indemnification.

               (a) Indemnification by the Company. The Company shall, without limitation as to time,
indemnify and hold harmless, to the fullest extent permitted by law, each holder of Registrable
Securities whose Registrable Securities are covered by a Registration Statement or Prospectus, the
officers, directors, partners, members, managers, shareholders, accountants, attorneys, 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) and the officers, directors, partners,
members, managers, shareholders, accountants, attorneys, agents and employees of each such
controlling Person, each underwriter, if any, and each Person who controls (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act) such underwriter, from and
against any and all losses, claims, damages, liabilities, costs (including, without limitation,
costs of preparation and reasonable attorneys’ fees and any legal or other fees or expenses
incurred by such party in connection with any investigation or Proceeding), expenses, judgments,
fines, penalties, charges and amounts paid in settlement (collectively, “Losses”), as
incurred, arising out of or based upon any untrue statement (or alleged untrue statement) of a
material fact contained in any Prospectus, offering circular, or other document (including any
related Registration Statement, notification, or the like) incident to any such registration,
qualification, or compliance, or based on any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements therein not
misleading, or any violation by the Company of the Securities Act, the Exchange Act, any state
securities law, or any rule or regulation thereunder applicable to the Company and (without
limitation of the preceding portions of this Section 8(a)) will reimburse each such holder, each of
its officers, directors, partners, members, managers, shareholders, accountants, attorneys, agents
and employees and each Person who controls each such holder and the officers, directors, partners,
members, managers, shareholders, accountants, attorneys, agents and employees of each such
controlling Person, each such underwriter, and each Person who controls any such underwriter, for
any legal and any other expenses reasonably incurred in connection with investigating and defending
or settling any such claim, loss, damage,
liability, or action, provided that the Company will not be liable in any such case to the
extent that any such claim, Loss, damage, liability, or expense arises out of or is based on any
untrue statement or omission by such holder or underwriter, but only to the extent, that such
untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such
Registration Statement, Prospectus, offering circular, or other document in reliance upon and in
conformity with written information furnished to the Company by such holder for use therein. It is
agreed that the indemnity agreement contained in this Section 8(a) shall not apply to amounts paid
in settlement of any such loss, claim, damage, liability, or action if such settlement is

15

 

effected
without the consent of the Company (which consent shall not be unreasonably withheld or delayed).

               (b) Indemnification by Holder of Registrable Securities. The Company may require, as
a condition to including any Registrable Securities in any registration statement filed in
accordance with this Agreement, that the Company shall have received an undertaking reasonably
satisfactory to it from the prospective seller of such Registrable Securities to indemnify, to the
fullest extent permitted by law, severally and not jointly with any other holders of Registrable
Securities, the Company, its directors and officers and each Person who controls the Company
(within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act) and all
other prospective sellers, from and against all Losses arising out of or based on any untrue
statement of a material fact contained in any such Registration Statement, Prospectus, offering
circular, or other document, or any omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and to (without limitation of
the preceding portions of this Section 8(b)) reimburse the Company, its directors and officers and
each Person who controls the Company (within the meaning of Section 15 of the Securities Act and
Section 20 of the Exchange Act) and all other prospective sellers for any legal or any other
expenses reasonably incurred in connection with investigating or defending any such claim, loss,
damage, liability, or action, in each case to the extent, but only to the extent, that such untrue
statement or omission is made in such Registration Statement, Prospectus, offering circular, or
other document in reliance upon and in conformity with written information furnished to the Company
by such holder for inclusion in such Registration Statement, Prospectus, offering circular or other
document; provided, however, that the obligations of such holder under such
undertaking shall not apply to amounts paid in settlement of any such claims, losses, damages, or
liabilities (or actions in respect thereof) if such settlement is effected without the consent of
such holder (which consent shall not be unreasonably withheld or delayed); and provided,
further, that the liability of such holder of Registrable Securities shall be limited to
the net proceeds received by such selling holder from the sale of Registrable Securities covered by
such Registration Statement.

               (c) Conduct of Indemnification Proceedings. If any Person shall be entitled to
indemnity hereunder or under the undertaking contemplated by Section 8(b) (an “Indemnified
Party”), such Indemnified Party shall give prompt notice to the party from which such indemnity
is sought (the “Indemnifying Party”) of any claim or of the commencement of any Proceeding
with respect to which such Indemnified Party seeks indemnification or contribution pursuant hereto;
provided, however, that the delay or failure to so notify the Indemnifying Party
shall not relieve the Indemnifying Party from any obligation or liability except to the extent that
the Indemnifying Party has been materially prejudiced by such delay or failure. The Indemnifying
Party 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 claim or Proceeding, to, unless in the Indemnified Party’s reasonable judgment a conflict of
interest between such indemnified and indemnifying parties may exist in respect of such claim,
assume, at the Indemnifying Party’s expense, the defense of any such claim or Proceeding, with
counsel reasonably satisfactory to such Indemnified Party; provided, however, that
an Indemnified Party shall have the right to employ separate counsel in any such claim or
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 unless: (i) the Indemnifying Party agrees to pay

16

 

such fees and expenses; or (ii) the Indemnifying Party fails promptly to assume, or in the event of
a conflict of interest cannot assume, the defense of such claim or Proceeding or fails to employ
counsel reasonably satisfactory to such Indemnified Party, in which case the Indemnified Party
shall have the right to employ separate counsel and to assume the defense of such claim or
proceeding at the Indemnifying Party’s expense; provided, further, however,
that the Indemnifying Party shall not, in connection with any one such claim or Proceeding or
separate but substantially similar or related claims or 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 firm of attorneys (together with appropriate local counsel) at any time for all of
the Indemnified Parties, or for fees and expenses that are not reasonable. Whether or not such
defense is assumed by the Indemnifying Party, such Indemnifying Party will not be subject to any
liability for any settlement made without its consent (but such consent will not be unreasonably
withheld). The Indemnifying Party shall not consent to entry of any judgment or enter into any
settlement that does not include as an unconditional term thereof the giving by the claimant or
plaintiff to such Indemnified Party of a release, in form and substance reasonably satisfactory to
the Indemnified Party, from all liability in respect of such claim or litigation for which such
Indemnified Party would be entitled to indemnification hereunder.

               (d) Contribution. If the indemnification provided for in this Section 8 is
unavailable to an Indemnified Party in respect of any Losses (other than in accordance with its
terms), then each applicable Indemnifying Party, in lieu of indemnifying such Indemnified Party,
shall 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 made (or omitted) 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 parties hereto agree that it would not be just and equitable if contribution pursuant to
this Section 8(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 the immediately preceding
paragraph. Notwithstanding the provisions of this Section 8(d), an Indemnifying Party that is a
selling holder of Registrable Securities (other than the Company) shall not be required to
contribute any amount in excess of the amount that such Indemnifying
Party has otherwise been, or would otherwise be, required to pay pursuant to Section 8(b) by
reason 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.

               (e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and
contribution contained in the underwriting agreement entered into in

17

 

connection with the
underwritten public offering are in conflict with the foregoing provisions, the provisions in the
underwriting agreement shall control.

     Section 9. Rule 144.

               (a) After an initial Public Offering, the Company shall (i) use reasonable best efforts to
file the reports required to be filed by it under the Securities Act and the Exchange Act in a
timely manner, (ii) take such further action as any holder of Registrable Securities may reasonably
request, and (iii) furnish to each holder of Registrable Securities forthwith upon written request,
(x) a written statement by the Company as to its compliance with the reporting requirements of Rule
144, the Securities Act and the Exchange Act, (y) a copy of the most recent annual or quarterly
report of the Company, and (z) such other reports and documents so filed by the Company as such
holder may reasonably request in availing itself of Rule 144, 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 limitations of the exemption provided by Rule 144. 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.

               (b) The foregoing provisions of this Section 9 are not intended to modify or otherwise affect
any restrictions on transfers of securities contained in the LLC Agreement or any stockholders or
investors rights agreement to which a Shareholder may be subject relating to Registrable
Securities.

     Section 10. Underwritten Registrations. If any Demand Registration is an underwritten
offering, the holders of a majority of the Registrable Securities to be included in such Demand
Registration shall have the right to select the investment banker or investment bankers and
managers to administer the offering. The Company shall have the right to select the investment
banker or investment bankers and managers to administer any Piggyback Registration.

          No Person may participate in any underwritten registration hereunder unless such Person (i)
agrees to sell the Registrable Securities it desires to have covered by a Registration Statement on
the basis provided in any underwriting arrangements in customary form and (ii) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other
documents reasonably required under the terms of such underwriting arrangements, provided that such
Person shall not be required to make any representations or warranties other than those related to
title and ownership of such Person’s shares and as to the accuracy and completeness of statements
made in a Registration Statement, Prospectus, offering
circular, or other document in reliance upon and in conformity with written information
furnished to the Company or the managing underwriter by such Person for use therein.

     Section 11. Alternative IPO Entities. In the event that the Company, EFH or any of
its subsidiaries elects, subject to the terms and conditions of the Investor Rights Agreement, to
effect an underwritten public offering of equity securities for an entity, the only material asset
of which is its direct or indirect interest in the Company or all or substantially all of the
assets of the Company (such entity, the “Alternative IPO Entity”), rather than the LLC
Units,
whether as a

18

 

result of a reorganization of the Company or otherwise, and subject in each
case to the provisions of the Investor Rights Agreement, EFH and the Company shall cause the
Alternative IPO Entity to enter into an agreement with the Shareholders (or (i) if the Alternative
IPO Entity is a Shareholder, then with respect to that Shareholder, that Shareholder’s parent
entity, and (ii) upon the consummation of an Equity and Debt Transfer (as defined in the Investor
Rights Agreement), then, with respect to the Minority Member, the Indirect Shareholders (as defined
in the Investor Rights Agreement)) that provides the Shareholders (or such parent entity or group
of Indirect Shareholders, as applicable) with registration rights with respect to the equity
securities of the Alternative IPO Entity that are substantially the same as, and in any event no
less favorable in the aggregate to, the registration rights provided to the Shareholders in this
Agreement; provided that, for purposes of providing registration rights to the Indirect
Shareholders, the Indirect Shareholders shall be treated as a single entity and the sufficiency of
such registration rights shall be considered on the basis of the aggregate registration rights
granted to the Indirect Shareholders collectively. Subject to the provisions of the Investor
Rights Agreement, the Shareholders agree to cooperate and take all necessary or desirable actions
to effect any such reorganization, recapitalization, restructuring or similar transaction,
including the conversion of the LLC Units into a substantially equivalent common equity security in
the Alternative IPO Entity (acknowledging that the Alternative IPO Entity may be an entity treated
as a corporation for federal income tax purposes).

     Section 12. Miscellaneous.

               (a) Amendments and Waivers. The provisions of this Agreement, including the
provisions of this section, may not be amended, restated, modified or supplemented, and waivers or
consents to departures from the provisions hereof may not be given without the written consent of
the Initial Member; provided, however, that any modification, alteration,
supplement or amendment of this Agreement that has a disproportionate material adverse effect on
the rights, obligations, powers or interests of any Shareholder in its capacity as a Shareholder
relative to all Shareholders in their capacities as Shareholders, shall require the agreement of
such Shareholder. Notwithstanding the foregoing, a waiver or consent to depart from the provisions
hereof with respect to a matter that relates exclusively to the rights of holders of Registrable
Securities whose securities are being sold pursuant to a Registration Statement and that does not
directly or indirectly affect the rights of other holders of Registrable Securities may be given by
those holders of the Registrable Securities being sold by such holders pursuant to such
Registration Statement that would be required to approve such matter under this Section 12(a) as if
such holders were the only Shareholders remaining.

               (b) Notices. Except as expressly set forth to the contrary in this Agreement, all
notices, requests or consents provided for or required to be given hereunder shall be in writing
and shall be deemed to be duly given if personally delivered; telecopied and confirmed; mailed by
certified mail, return receipt requested; or sent via nationally recognized overnight delivery

delivered by telecopy, be deemed received on the first business day following confirmation; shall,

          Whenever any notice is required to be given by Law or this Agreement, a written waiver
thereof, signed by the Person entitled to notice, whether before or after the time stated therein,
shall be deemed equivalent to the giving of such notice.

               (c) Successors and Assigns. This Agreement shall inure to the benefit of and be
binding upon the successors and permitted assigns of each of the parties, including the Company and
subsequent holders of Registrable Securities acquired, directly or indirectly, from the
Shareholders in transfers otherwise permitted pursuant to the LLC Agreement and Investor Rights
Agreement; provided, however, that such successor or assign shall not be entitled
to such rights unless the successor or assign shall have executed and delivered to the Company an
Addendum Agreement substantially in the form of Exhibit A hereto (which shall also be executed by
the Company) promptly following the acquisition of such Registrable Securities, in which event such
successor or assign shall be deemed a Shareholder for purposes of this Agreement. Except as
provided in Section 8 with respect to an Indemnified Party, nothing expressed or mentioned in this
Agreement is intended or shall be construed to give any Person other than the parties hereto and
their respective successors and permitted assigns any legal or equitable right, remedy or claim
under, in or in respect of this Agreement or any provision herein contained.

               (d) Counterparts. This Agreement may be executed in two or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute one and the same
instrument.

               (e) Headings. The section and paragraph headings contained in this Agreement are for
reference purposes only and shall not affect in any way the meaning or interpretation of this
Agreement.

               (f) Governing Law; Judicial Proceedings. This Agreement shall be governed by and
construed in accordance with the Laws of the State of New York without giving effect to any
otherwise governing principles of conflicts of law.

21

 

               (g) Severability. If any term, provision, covenant or restriction of this Agreement
is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the
remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in
full force and effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their best efforts to find and employ an alternative means to achieve the same or
substantially the same result as that contemplated by such term, provision, covenant or
restriction. It is hereby stipulated and declared to be the intention of the parties that they
would have executed the remaining terms, provisions, covenants and restrictions without including
any of such that may be hereafter declared invalid, illegal, void or unenforceable.

               (h) Entire Agreement. This Agreement, the LLC Agreement, the Subscription Agreement
and the Investor Rights Agreement are intended by the parties as a final expression of their
agreement, and are intended to be a complete and exclusive statement of the agreement and
understanding of the parties hereto in respect of the subject matter contained herein and therein.
There are no restrictions, promises, warranties or undertakings, other than those set forth or
referred to herein and therein, with respect to the registration rights granted by the Company with
respect to Registrable Securities. This Agreement, together with the LLC Agreement, the
Subscription Agreement and the Investor Rights Agreement, supersedes all prior agreements and
understandings between the parties with respect to such subject matter.

               (i) Securities Held by the Company or its Subsidiaries. Whenever the consent or
approval of holders of a specified percentage of Registrable Securities is required hereunder,
Registrable Securities held by the Company or its subsidiaries shall not be counted in determining
whether such consent or approval was given by the holders of such required percentage.

               (j) Specific Performance. The parties hereto recognize and agree that money damages
may be insufficient to compensate the holders of any Registrable Securities for breaches by the
Company of the terms hereof and, consequently, that the equitable remedy of specific performance of
the terms hereof will be available in the event of any such breach.

               (k) Term. This Agreement shall terminate with respect to a Shareholder on the date on
which such Shareholder ceases to hold Registrable Securities; provided, that such
Shareholder’s rights and obligations pursuant to Section 8, as well as the Company’s obligations to
pay expenses pursuant to Section 7, shall survive with respect to any registration statement in
which any Registrable Securities of such Shareholder were included and, for the avoidance of doubt,
any underwriter lock-up that a Shareholder has executed prior to a Shareholder’s termination in
accordance with this Section 12(k) shall remain in effect in accordance with its terms.

               (l) Consent to Jurisdiction. The parties hereto hereby irrevocably submit to the
non-exclusive jurisdiction of any state court sitting in the City of New York, Borough of Manhattan
and the United States District Court for the Southern District of New York, and appropriate
appellate courts therefrom, over any dispute arising out of or relating to this Agreement or any of
the transactions contemplated hereby, and each party hereby irrevocably agrees that all claims in
respect of such dispute or proceeding may be heard and determined in such courts. The parties
hereby irrevocably waive, to the fullest extent permitted

22

 

by applicable law, any objection which
they may now or hereafter have to the laying of venue of any dispute arising out of or relating to
this Agreement or any of the transactions contemplated hereby brought in such court or any defense
of inconvenient forum for the maintenance of such dispute. Each of the parties hereto agrees that
a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in
any other manner provided by law. This consent to jurisdiction is being given solely for purposes
of this Agreement and is not intended to, and shall not, confer consent to jurisdiction with
respect to any other dispute in which a party to this Agreement may become involved.

          Each of the parties hereto hereby consents to process being served by any party to this
Agreement in any suit, action, or proceeding of the nature specified in the paragraph above by the
mailing of a copy thereof in the manner specified by the provisions of subsection (b) of this
Section 12.

          EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,
PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT.

23

 

          IN WITNESS WHEREOF, the parties hereto have caused this Registration Rights Agreement to be
duly executed as of the date first above written.

admitted as a member of the Company; and

          WHEREAS, pursuant to the Amended and Restated Limited Liability Company Agreement of Oncor
Electric Delivery Company LLC, dated October 10, 2007 (the “Amended LLC Agreement”), the
Initial LLC Agreement was amended and restated.

          NOW THEREFORE, the Members, by their execution of this Agreement, hereby amend and restate the
Amended LLC Agreement to provide, among other things, for the admission of each of the Minority
Member and the Management Member as Members, and further agree as follows:

Section 1. Name.

          The name of the limited liability company continued hereby is ONCOR ELECTRIC DELIVERY COMPANY
LLC.

Section 5. Fiscal Year.

     Unless otherwise determined by the Board, the fiscal year of the Company shall be the calendar
year.

Section 6. Members; Membership Interests; Actions by Members.

     (a) The mailing address of each Member is set forth on Schedule B attached hereto.
Each of the Initial Member, the Minority Member and the Management Member (effective, in respect of
the Management Member, on the date it is first issued LLC Units) is hereby or was heretofore
admitted to the Company as a member of the Company, and hereby continues as such. Unless admitted
to the Company as a Member as provided in this Agreement, no Person shall be, or shall be
considered, a Member.

     (b) The Interests will be evidenced by LLC Units, which LLC Units shall represent and include
any and all benefits to which each Member is entitled as provided in this Agreement, together with
all obligations of such Member to comply with the terms and conditions of this Agreement. Each
Interest will constitute a “security” within the meaning of, and governed by, (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) Article 8 of 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 Institute and the National Conference of Commissioners on Uniform
State Laws and approved by the American Bar Association on February 14, 1995. Notwithstanding any
provision of this Agreement to the contrary, to the extent that any provision of this Agreement is
inconsistent with any non-waivable provision of Article 8 of the Uniform Commercial Code as in
effect in the State of Delaware (6 Del. C. § 8-101, et seq.) (the “UCC”), such provision of
Article 8 of the UCC shall control.

     (c) Unit Certificates. Unless and until the Board shall determine otherwise, LLC
Units shall be uncertificated and recorded in the books and records of the Company (including

- 2 -

 

Schedule B). To the extent any LLC Units are certificated, such certificates shall be in
the form approved by the Board from time to time. The Board may determine the conditions upon
which a new LLC Unit certificate may be issued in place of a certificate that is alleged to have
been lost, stolen or destroyed and may, in its discretion, require the owner of such certificate or
its legal representative to give an agreement of indemnity or a bond, with sufficient surety, to
indemnify the Company and each transfer agent and registrar agent, if any, against any and all
losses and claims that may arise as a result of the issuance of a new certificate in place of the
one so lost, stolen or destroyed. Each LLC Unit certificate shall bear a legend on the face
thereof in the following form:

          “TRANSFER IS SUBJECT TO RESTRICTIVE LEGENDS ON BACK.”

     and shall bear a legend on the reverse side thereof substantially in the following form:

“THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF
1933, AS AMENDED (THE “SECURITIES ACT”) OR UNDER THE LAWS OF ANY STATE OR FOREIGN
JURISDICTION, AND MAY NOT BE OFFERED OR SOLD, UNLESS IT HAS BEEN REGISTERED UNDER
THE SECURITIES ACT OR UNLESS AN EXEMPTION FROM REGISTRATION IS AVAILABLE (AND, IN
SUCH CASE, AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE BOARD OF DIRECTORS
SHALL HAVE BEEN DELIVERED TO THE COMPANY TO THE EFFECT THAT SUCH OFFER OR SALE IS
NOT REQUIRED TO BE REGISTERED UNDER THE SECURITIES ACT OR ANY OTHER APPLICABLE
FEDERAL, FOREIGN, STATE, PROVINCIAL, SECURITIES OR OTHER SIMILAR LAWS). EACH
INTEREST SHALL CONSTITUTE A “SECURITY” WITHIN THE MEANING OF, AND GOVERNED BY, (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) ARTICLE 8 OF 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 INSTITUTE AND THE NATIONAL CONFERENCE OF COMMISSIONERS ON UNIFORM STATE
LAWS AND APPROVED BY THE AMERICAN BAR ASSOCIATION ON FEBRUARY 14, 1995.
NOTWITHSTANDING ANY PROVISION OF THE SECOND AMENDED AND RESTATED LIMITED LIABILITY
COMPANY AGREEMENT OF ONCOR ELECTRIC DELIVERY COMPANY LLC (THE “LLC AGREEMENT”) TO
THE CONTRARY, TO THE EXTENT THAT ANY PROVISION OF THE LLC AGREEMENT IS INCONSISTENT
WITH ANY NON-WAIVABLE PROVISION OF ARTICLE 8 OF THE UNIFORM COMMERCIAL CODE AS IN
EFFECT IN THE STATE OF DELAWARE (6 DEL. C. § 8-101, ET SEQ.) (THE “UCC”), SUCH
PROVISION OF
ARTICLE 8 OF THE UCC SHALL CONTROL. THIS SECURITY IS SUBJECT TO CERTAIN RESTRICTIONS
ON TRANSFER AND OTHER

- 3 -

 

TERMS AND CONDITIONS SET FORTH IN THE LLC AGREEMENT AND AN
INVESTOR RIGHTS AGREEMENT RELATING TO THE COMPANY, EACH DATED AS OF •, 2008, AS
EITHER MAY BE AMENDED FROM TIME TO TIME, COPIES OF WHICH MAY BE OBTAINED FROM THE
COMPANY AT ITS PRINCIPAL BUSINESS OFFICE. ANY TRANSFER MADE IN CONTRAVENTION OF
SUCH RESTRICTIONS ON TRANSFER SHALL BE, TO THE FULLEST EXTENT PERMITTED BY LAW, NULL
AND VOID.”

     (d) In addition to the legend required by Section 6(c) above, each Member agrees that each LLC
Unit certificate heretofore or hereafter issued by the Company shall also bear such other legends
as may be required by Law or the Board, including any such legend that the Members shall direct the
Board to include pursuant to any investor rights agreement, sale participation agreement or
shareholders agreement. Any such legend and the legend set forth in Section 6(c) shall be removed
by the Board upon the request (which shall include customary representations and opinions of
counsel if reasonably requested by the Board) of a Member when such legend is no longer applicable.

     (e) Unless otherwise specified herein, any matter requiring the action, consent or approval of
the Members hereunder shall require action, consent or approval of the Members owning at least a
majority of the LLC Units.

     (f) Subject to Section 10(i), the Members may act by written consent.

Section 7. Certificate of Formation.

     Jared Richardson, an “authorized person” within the meaning of the Act, executed, delivered
and filed the Certificate of Conversion and the Certificate of Formation of the Company with the
Secretary of State of the State of Delaware. Upon the filing of the Certificate of Conversion and
the Certificate of Formation with the Secretary of State of the State of Delaware, his powers as an
“authorized person” ceased, and the Initial Member thereupon became a member of the Company and the
designated “authorized person” and shall continue as the designated “authorized person” within the
meaning of the Act. The Initial Member or an Officer shall execute, deliver and file any other
certificates (and any amendments and/or restatements thereof) necessary for the Company to qualify
to do business in Texas and in any other jurisdiction in which the Company may wish to conduct
business.

     The existence of the Company as a separate legal entity shall continue until cancellation of
the Certificate of Formation as provided in the Act.

Section 8. Purpose.

     Subject to Section 10(i), the purposes to be conducted or promoted by the Company
(directly or through its Subsidiaries) are those of an electric transmission and distribution
company, including owning or operating equipment or facilities to transmit and distribute
electricity, and to engage in any other activities related or incidental thereto or in
anticipation thereof (which, for the avoidance of doubt, shall include the activities of Transition
Bond Co. as currently conducted on the date hereof).

- 4 -

 

Section 9. Powers.

     Subject to Section 10(i), the Company, and the Board of Directors and the Officers of
the Company on behalf of the Company, (i) shall have and exercise all powers necessary, convenient
or incidental to accomplish its purposes as set forth in Section 8 and (ii) shall have and
exercise all of the powers and rights conferred upon limited liability companies formed pursuant to
the Act.

Section 10. Management.

     (a) Board of Directors. Subject to Section 10(i), the business and affairs of
the Company shall be managed by or under the direction of the Board and not by or under the
direction of any EFH Group member or any officer or employee thereof. The Board shall have eleven
(11) Directors (subject to reduction as provided below), each of which shall be a natural person:

	 	(i)	 	two (2) of which Directors (x) prior to a Trigger Event (I)
will be designated by the Minority Member (or its Permitted Transferee), and
indirectly through the Minority Member (or its Permitted Transferee) (pursuant
to the applicable provisions set forth in the limited liability company
agreement or similar governing document(s) of the Minority Member or its
Permitted Transferee) solely by a Person or Persons (each, a “Non-Parent
Affiliated Investor”) each of whom (1) directly or indirectly has a limited
liability company interest in the Minority Member (or its Permitted Transferee)
and (2) does not hold any Direct or Indirect EFH Interest and (II) shall be an
employee or representative of a Non-Parent Affiliated Investor and (y)
following a Trigger Event will be designated by the Minority Member (or its
Permitted Transferee) as it determines in its sole discretion (any Director
meeting the foregoing requirements, a “Minority Member Director”, and
together with the Directors nominated by the Initial Member and the Director
who is an officer of the Company, the “Member Directors”);
provided, however, that (A) if the Minority Member (together
with its Permitted Transferees) holds less than 15% of the then aggregate
outstanding LLC Units but not less than 7.5% of the then aggregate outstanding
LLC Units, the Minority Member (or its Permitted Transferee) will designate one
(1) Minority Member Director and (B) if the Minority Member (together with its
Permitted Transferees) holds less than 7.5% of the then aggregate outstanding
LLC Units, the Minority Member (or its Permitted Transferee) will not be
entitled to designate any Directors. In the event that, in accordance with the
immediately preceding sentence, the Minority Member (or its Permitted
Transferee) (A) has the ability to designate only one (1) Director, or (B) does
not have the ability to designate any Directors, then the total number
of Directors shall be reduced accordingly (i.e., by the number of Directors
that the Minority Member (or its Permitted Transferee) is no longer entitled
to designate);

- 5 -

 

	 	(ii)	 	six (6) of which Directors will be Independent Directors (two
of which will be Special Independent Directors) designated by the Initial
Member only at the direction, in writing, of the nominating committee of the
Initial Member’s board of directors;
	 
	 	(iii)	 	two (2) of which Directors will be Member Directors designated
by the Initial Member, only at the direction, in writing, of the board of
directors of the sole member of the Initial Member; and
	 
	 	(iv)	 	one (1) of which Directors will be an officer of the Company
designated by the Initial Member only at the direction, in writing, of the
board of directors of the sole member of the Initial Member.

The eleven (11) Directors as of the date hereof are listed on Schedule D hereto. Each
Director elected, designated, nominated or appointed in accordance with this Agreement shall hold
office (1) until a successor is elected, designated, nominated or appointed and qualified in
accordance with this Agreement, (2) in the case of an Independent Director or a Special Independent
Director, until such Director fails to qualify as an Independent Director or Special Independent
Director, as applicable, (3) in the case of a Minority Member Director, until such Director fails
to qualify as a Minority Member Director or (4) until such Director’s earlier death, resignation,
expulsion or removal. Each Director shall execute and deliver the Management Agreement. No
Director shall be required to be a Member. No Director may concurrently serve as a director of any
Subsidiary of Texas Competitive Electric Holdings Company LLC, including any entity that Luminant
Holding Company LLC or TXU Energy Company LLC controls.

     In addition to the right to designate Minority Member Directors as provided in Section
10(a)(i), prior to a Trigger Event, the Minority Member shall also have the right, so long as the
Minority Member is a Principal Member to designate one non-voting observer to the Board (the
“Board Observer”) who will be entitled to attend all meetings of the Board and receive
copies of all notices and other materials provided to the Board, provided that the Board
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 (x) shall be entitled to exclude
the Board Observer from such portions of a Board meeting to the extent the Board reasonably
determines, after consulting with counsel, that the Board Observer’s presence would be reasonably
likely to result in the waiver of attorney-client privilege and (y) shall exclude the Board
Observer from that portion of any meeting of the Board related to the discussion of any dividends
or distributions to be made by the Company to holders of LLC Units or any transaction contemplated
to be entered into between the Company and/or any of its Subsidiaries, on the one hand, and any
member of the EFH Group, on the other hand.

     Notwithstanding anything to the contrary in Section 10(a)(i), prior to a Trigger Event, in
respect of any Minority Member Director (other than a Minority Member Director who is an employee
of OMERS Administration Corporation, Borealis Infrastructure Management Inc. or
any of their Affiliates), in the event that a majority of the Independent Directors reasonably
determine that such Minority Member Director’s status as a Director is reasonably likely to result
in any downgrade of the Company’s credit ratings, the Minority Member agrees to remove such Person
as a Minority Member Director and to appoint another Person in replacement of such

- 6 -

 

removed Minority
Member Director that would comply with the requirements set forth in Section 10(a)(i).

     If necessary under applicable law, each Member agrees to vote its LLC Units to effectuate the
provisions of this Section 10(a).

     (b) Powers. Subject to Section 10(i), the Board shall have the power to do
any and all acts necessary, convenient or incidental to or for the furtherance of the purposes
described herein, including all powers, statutory or otherwise. The Board has the authority to
bind the Company. To the extent of their powers set forth in this Agreement and subject to
Section 10(i), the Directors are agents of the Company for the purpose of the Company’s
business, and the actions of the Directors taken in accordance with such powers set forth in this
Agreement shall bind the Company. Notwithstanding the last sentence of Section 18 402 of the Act,
except as provided in this Agreement or in a resolution of the Directors, a Director may not bind
the Company.

     (c) Meetings of the Board. The Board may hold meetings, both regular and special,
within or outside the State of Delaware. Regular meetings of the Board may be held at such time
and at such place as shall from time to time be determined by the Board and communicated in writing
to each Director; provided, that, upon such communication to each Director of the
Board’s determination of the time and place of a regular meeting, no further notice of any regular
meeting to be held at such time and place need be given to any Director, but if the Board
determines to make any change with respect to the time or place of a regular meeting, five (5)
days’ notice of such change shall be communicated in writing to each Director before such change
becomes effective. Special meetings of the Board may be called by the Chief Executive Officer on
not less than five (5) days’ written notice to each Director by facsimile, mail, telegram or any
other means of written communication, and special meetings shall be called by the Chief Executive
Officer, the President or the Secretary in like manner and with like notice upon the written
request of any one or more of the Directors; provided, that, notice of a special
meeting shall not be required if waived by all Directors, which waiver shall be assumed for any
Director attending such special meeting unless attending to object to such meeting. The Board
Observer shall be entitled to notice of meetings of the Board as if he or she were a Director,
provided that the failure to provide the Board Observer with notice of a Board meeting
shall not affect the validity of any actions taken thereat, and provided further
that no waiver of notice of a Board meeting from the Board Observer shall be required where all
Directors have waived such notice and are relying thereon.

     (d) Quorum; Acts of the Board. Subject to Section 10(i), at all meetings of
the Board, a majority of the Directors shall constitute a quorum for the transaction of business
and, except as otherwise provided in any other provision of this Agreement, the act of a majority
of the Directors present at any meeting at which there is a quorum shall be the act of the Board.
For the avoidance of doubt, the attendance (or non-attendance) at a meeting of the Board by the
Board Observer shall not be taken into account for purposes of determining whether a quorum is
present. If a quorum shall not be present at any meeting of the Board, the Directors present at such meeting may adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present. Any action required or permitted to be taken at any meeting of the Board or of any committee thereof may be taken without a

- 7 -

 

meeting if all members of the Board or committee, as the case may be, consent thereto in
writing, and the writing or writings are filed with the minutes of proceedings of the Board or
committee, as the case may be.

     (e) Electronic Communications. Members of the Board, or any committee designated by
the Board, may participate in meetings of the Board, or any committee, by means of telephone
conference or similar communications equipment that allows all Persons participating in the meeting
to hear each other, and such participation in a meeting shall constitute presence in person at the
meeting. If all the participants are participating by telephone conference or similar
communications equipment, the meeting shall be deemed to be held at the principal place of business
of the Company.

     (f) Committees of Directors.

	 	(i)	 	The Board may, by resolution passed by a majority of the whole
Board, designate one or more committees, each committee to consist of one or
more of the Directors of the Company. The Board may designate one or more
Directors as alternate members of any committee, who may replace any absent or
disqualified member at any meeting of the committee.
	 
	 	(ii)	 	In the absence or disqualification of a member of a committee,
the member or members thereof present at any meeting and not disqualified from
voting, whether or not such members constitute a quorum, may unanimously
appoint another member of the Board to act at the meeting in the place of any
such absent or disqualified member.
	 
	 	(iii)	 	Any such committee, to the extent provided in the resolution
of the Board designating such committee, and subject to, in all cases,
Sections 10(i) and 11, shall have and may exercise all the powers and
authority of the Board in the management of the business and affairs of the
Company specified in the resolution of the Board designating such committee.
Such committee or committees shall have such name or names as may be determined
from time to time by resolution adopted by the Board. Each committee shall
keep regular minutes of its meetings and report the same to the Board when
required.

     (g) Compensation of Directors; Expenses. The Board shall have the authority to fix
the compensation of Directors. The Directors may be paid their expenses, if any, of attendance at
meetings of the Board, which may be a fixed sum for attendance at each meeting of the Board or a
stated salary as Director. No such payment shall preclude any Director from serving the Company in
any other capacity and receiving compensation therefor. Members of special or standing committees
may be allowed additional compensation for attending committee meetings. Chairpersons of standing
or special committees may receive compensation, in their capacities as such chairpersons, in
addition to any compensation received as a member of any such committee. The Board Observer shall
be entitled to reimbursement for expenses, if any, of attendance of meetings of the Board to the
same extent as if he or she were a Director, but shall not be entitled to any other compensation
from the Company.

- 8 -

 

     (h) Removal of Directors. Unless otherwise restricted by Law, and subject to
Section 11, (i) any Minority Member Director designated by the Minority Member may be
removed or expelled, with or without cause, at any time by the Minority Member, and any vacancy
caused by any such removal or expulsion, or otherwise, may be filled by action of the Minority
Member; provided that, in the event the Minority Member no longer has the right to
designate the number of Directors that are currently sitting on the Board as Minority Member
Directors, one or both (in accordance with the percentage of the outstanding LLC Units held by the
Minority Member and its Permitted Transferees) of the Minority Member Directors shall be
automatically removed without any further action by the Minority Member (or its Permitted
Transferee) being necessary to effect such removal (in the event that only one of two Minority
Member Directors currently sitting on the Board will be removed in accordance with Section 10(a)(i)
and this Section 10(h)(i), the Minority Member (or its Permitted Transferee) shall specify the
Director to be removed prior to (or, in the case of inaction where the Minority Member (or its
Permitted Transferee) is not initially aware of the loss of right to designate a Director,
immediately upon notice thereof) any action/inaction by the Minority Member (or its Permitted
Transferees) that will trigger any removal of a Director pursuant to Section 10(a)(i) and this
Section 10(h)(i), and in that case such Director shall be automatically removed under this Section

- 10 -

 

	 	 	 	Members may amend any provision hereof reasonably required in good faith to
accommodate the admission of any additional Member, other than an Affiliate
of Energy Future Holdings Corp. (including the establishment of relative
voting rights of the Members and an increase in the number of Directors,

designated by the Initial Member present and voting and all of the Independent

	 	(v)	 	The Board and the Members shall cause the Company to do or
cause to be done all things necessary to preserve and keep in full force and
effect its existence, rights (charter and statutory) and franchises as well as
the existence, rights (charter and statutory) and franchises of its
Subsidiaries; provided, however, that the Company shall not be
required to preserve any such right or franchise if the Board shall determine
that the preservation thereof is no longer desirable for the conduct of its
business and that the loss thereof is not disadvantageous in any material
respect to the Company.
	 
	 	(vi)	 	To ensure separateness from the EFH Group, so long as any

jointly contract or do business with vendors or service providers or
share overhead expenses, allocate fairly, appropriately and reasonably
the costs

	 	 	 	and expenses incurred in so doing between or among such entities,
with the result that each such entity bears its fair share of all
such costs and expenses;
	 
	 	(Q)	 	to the extent that it contracts or does
business with vendors or service providers where the goods or services
are wholly or partially for the benefit of the EFH Group members,
allocate fairly, appropriately and reasonably the costs incurred in so
doing to the entity for whose benefit the goods or services are
provided, with the result that each such entity bears its fair share of

a EFH Group member pursuant to a documented trust or similar
arrangement, and (2) commingled funds identified as exceptions to

	 	(AA)	 	maintain adequate capital and a sufficient

substantially as if the Company were a stand-alone corporation.
	 
	 	Failure of the Company, or any Member or the Board on behalf of the Company,
to comply with any of the foregoing covenants or any other covenants
contained in this Agreement shall not affect the status of the Company as a
separate legal entity or the limited liability of the Members or the
Directors.

	 	(vii)	 	Neither the Company nor any of its Subsidiaries shall take any
of the following actions:

- 15 -

Member Director must be present and voting in order to approve such
action and (y) a majority of the Independent Directors; and
	 
	 	(B)	 	prior to a Trigger Event, approve any annual
budget if the aggregate amount of the capital and operating and
maintenance expenditures in such annual budget is a more than 10%
decrease from the capital and operating and maintenance expenditures in
the annual budget for the immediately prior fiscal year, unless such
annual budget is approved by (x) a majority of the Independent
Directors and (y) the Minority Member Director(s) present and voting,
provided that at least one Minority Member Director must be present and
voting in order to approve such action; provided that budgeted amounts
for any emergency expenditures and any expenditures that results from
changes in regulatory or legal requirements, including, but not limited
to, regulatory rulings of the Public Utility Commission of Texas, shall
be disregarded when calculating such amounts.

	 	(viii)	 	To ensure separateness from the EFH Group members, the Company shall cause
each Subsidiary of the Company whose organizational documents do not contain
separateness provisions comparable to the provisions of Section 10(i)
(other than Transition Bond Co.) of this Agreement to take or refrain from
taking, as the case may be, actions with respect to such Subsidiary of the type
described in Section 10(i)(vi) hereof and shall cause each such
Subsidiary to take actions with respect to itself of the type described in
clauses (ii) and (iv) of the definition of Material Actions only if authorized
by the Directors in a manner similar to Section 10(i)(iv).

Section 11. Independent Directors.

     The Initial Member, at the direction, in writing, of the nominating committee of the Initial
Member’s board of directors, shall designate Independent Directors as necessary to cause, at all
times, (i) at least six (6) (or such greater number as shall constitute a majority of the Directors
if the number of Directors is ever increased by amendment to this Agreement) members of the Board
to be Independent Directors, at least two (2) of which Independent Directors shall be Special
Independent Directors. To the fullest extent permitted by applicable Law, including Section 18
1101(c) of the Act, the Independent Directors shall consider only the interests of the Company,
including its creditors, in acting or otherwise voting on any Material Action. No resignation or
removal of an Independent Director, and no appointment of a

- 16 -

 

successor Independent Director, shall be effective until such successor shall have accepted
his or her appointment as an Independent Director by a written instrument reasonably acceptable to
the Company, which may be a counterpart signature page to the Management Agreement. In the event
of a vacancy in the position of Independent Director, the Initial Member shall, as soon as
practicable at the direction, in writing, of the nominating committee of the Initial Member’s board
of directors, designate a successor Independent Director. All right, power and authority of the
Independent Directors shall be limited to the extent necessary to exercise those rights and perform
those duties specifically set forth in this Agreement. Except as provided in the second sentence
of this Section 11, in exercising their rights and performing their duties under this
Agreement, any Independent Director shall have fiduciary duties of loyalty and care identical to
those of a director of a business corporation organized under the General Corporation Law of the
State of Delaware. No Independent Director shall at any time serve as trustee in bankruptcy for
any Affiliate of the Company.

Section 12. Officers.

     (a) Officers. The Officers of the Company as of the date hereof are listed on
Schedule E hereto. The Officers of the Company shall consist of at least a Chief Executive
Officer, a President, a Secretary and a Treasurer. The appointment or removal of the Chief
Executive Officer or the Chief Financial Officer of the Company shall require a majority vote of
the Board, which shall in any event include the unanimous vote of the Member Directors designated
by the Initial Member (other than any such Member Director that is also an officer or employee of
the Company). Additional Officers of the Company, if any, shall be chosen by the Board. The Board
may also choose one or more Vice Presidents, Assistant Secretaries, and Assistant Treasurers. Any
number of offices may be held by the same person, except that the President and the Secretary shall
not be the same person. The Board may appoint such other Officers and agents as it shall deem
necessary or advisable who shall hold their offices for such terms and shall exercise such powers
and perform such duties as shall be determined from time to time by the Board. The salaries of all
Officers and agents of the Company shall be fixed by or in the manner prescribed by the Board. The
Officers of the Company shall hold office until their successors are chosen and qualified. Any
Officer, except as provided above with respect to the Chief Executive Officer and the Chief
Financial Officer, may be removed at any time, with or without cause, by the affirmative vote of a
majority of the Board. Any vacancy occurring in any office of the Company, except as provided
above with respect to the Chief Executive Officer and the Chief Financial Officer, shall be filled
by the Board. The Officers shall have such powers and duties as usually pertain to their offices,
respectively, as well as such powers and duties as may from time to time be conferred by the Board.
No Officer of the Company may concurrently be an officer of any EFH Group member.

     (b) Officers as Agents. The Officers, to the extent of their powers set forth in this
Agreement or otherwise vested in them by action of the Board not inconsistent with this Agreement,
are agents of the Company for the purpose of the Company’s business and, subject to Section
10(i), the actions of the Officers taken in accordance with such powers shall bind the Company.

     (c) Duties of Board and Officers. Except to the extent otherwise provided herein,
each Director and Officer shall have fiduciary duties of loyalty and care identical to those of

- 17 -

 

directors and officers of business corporations organized under the General Corporation Law of
the State of Delaware.

Section 13. Limited Liability.

     Except as otherwise expressly provided by the Act, the debts, obligations and liabilities of
the Company, whether arising in contract, tort or otherwise, shall be the debts, obligations and
liabilities solely of the Company, and neither any Member nor any Director (nor former Member or
Director) shall be obligated personally for any such debt, obligation or liability of the Company
solely by reason of being a Member or Director of the Company.

     The Members hereby agree that, except as otherwise expressly provided herein or required by
applicable law, no Member shall have an obligation to return money or other property paid or
distributed to such Member whether or not such distribution was in violation of the Act, except to
the extent arising from gross negligence, fraud, willful breach of this Agreement or a willful
illegal act of such Member. The agreement set forth in the immediately preceding sentence shall be
deemed to be a compromise for purposes of §18-502(b) of the Act. However, if any court of
competent jurisdiction holds that, notwithstanding the provisions of this Agreement, any Member is
obligated to make any such return, such obligation shall be the obligation of such Member and not
of any other Person.

Section 14. Capital Contributions.

     The Members have contributed to the Company property of an agreed value as listed on
Schedule B attached hereto.

Section 15. Additional Contributions.

     No Member is required to make any additional capital contribution to the Company. To the
extent that, with the written consent of the Board, any Member makes an additional capital
contribution to the Company, any Officer authorized by the Board shall revise Schedule B of
this Agreement to reflect such additional capital contribution. The provisions of this Agreement,
including this Section 15, are intended to benefit the Members and, to the fullest extent
permitted by law, shall not be construed as conferring any benefit upon any creditor of the Company
(and no such creditor of the Company shall be a third-party beneficiary of this Agreement) and the
Members shall not have any duty or obligation to any creditor of the Company to make any
contribution to the Company or to issue any call for capital pursuant to this Agreement.

Section 16. Tax Classification and Allocations of Profits and Losses.

     (a) Partnership Status. Subject to Section 3.7 of the Investor Rights Agreement, the
Board shall take such actions as are necessary to cause the Company and its Subsidiaries to be
treated as partnerships or disregarded entities, as the case may be, for federal income tax
purposes pursuant to Treasury Regulations Section 301.7701-3, and neither the Board nor any person
shall take any action that would affect such status without the prior written consent of each of
the Principal Members.

- 18 -

 

     (b) Capital Accounts. A separate capital account (a “Capital Account”) shall
be established and maintained for each Member in accordance with the provisions of Treasury
Regulation § 1.704-1(b)(2)(iv) and, to the extent not inconsistent with such regulation, the other
provisions of this Agreement. The Capital Account of each Member shall be credited with such
Member’s Capital Contributions with respect to the limited liability company interests in the
Company acquired by it, if any, all items of income and gain allocated to such Member pursuant to
Section 16(c) and any items of income or gain which are specially allocated pursuant to
Section 16(d); and shall be debited with all items of loss and deduction allocated to such
Member pursuant to Section 16(c), any items of loss or deduction of the Company specially
allocated to such Member pursuant to Section 16(d), and all cash and the Book Value of any
property (net of liabilities assumed by such Member and the liabilities to which such property is
subject) distributed by the Company to such Member. Any references in any section of this
Agreement to the Capital Account of a Member shall be deemed to refer to such Capital Account as
the same may be credited or debited from time to time as set forth above. In the event of any
transfer of any LLC Units (or portion thereof) in accordance with the terms of this Agreement, the
transferee shall succeed to the Capital Account of the transferor to the extent it relates to the
transferred limited liability company interests (or portion thereof).

     (c) Allocations of Profits and Losses. Except as otherwise provided in this
Agreement, Profits and Losses and to the extent necessary, individual items of income, gain or loss
or deduction of the Company shall be allocated in a manner such that the Capital Account of each
Member is, as nearly as possible, equal (proportionately) to (i) the distributions that would be
made pursuant to Section 17(a) if the Company were dissolved, its affairs wound up and its
assets sold for cash equal to their Book Value, all Company liabilities were satisfied (limited
with respect to each non-recourse liability to the Book Value of the assets securing such
liability) and the net assets of the Company were distributed in accordance with Section
17(a) to the Members immediately after making such allocation, minus (ii) such Member’s share
of Member Minimum Gain and Member Nonrecourse Debt Minimum Gain, computed immediately prior to the
hypothetical sale of assets.

     (d) Special Allocations. Notwithstanding any other provision in this Section
16:

	 	(i)	 	Minimum Gain Chargeback. If there is a net decrease in
Member Minimum Gain or Member Nonrecourse Debt Minimum Gain (determined in
accordance with the principles of Treasury Regulations Sections 1.704-2(d) and
1.704-2(i)) during any Company taxable year, the Members shall be specially
allocated items of Company income and gain for such year (and, if necessary,
subsequent years) in an amount equal to their respective shares of such net
decrease during such year, determined pursuant to Treasury Regulations Sections
1.704-2(g) and 1.704-2(i)(5). The items to be so allocated shall be determined
in accordance with Treasury Regulations Section 1.704-2(f). This Section
16(d)(i) is intended to comply with the minimum gain chargeback
requirements in such Treasury Regulations Sections and shall be interpreted
consistently therewith; including that no chargeback shall be required to the
extent of the exceptions provided in Treasury Regulations Sections 1.704-2(f)
and 1.704-2(i)(4).

- 19 -

 

	 	(ii)	 	Qualified Income Offset. If any Member unexpectedly
receives any adjustments, allocations, or distributions described in Treasury
Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Company
income and gain shall be specially allocated to such Member in an amount and
manner sufficient to eliminate the deficit balance in such Member’s Adjusted
Capital Account Balance created by such adjustments, allocations or
distributions as promptly as possible; provided, that an allocation
pursuant to this Section 16(d)(ii) shall be made only to the extent
that a Member would have a deficit Adjusted Capital Account Balance in excess
of such sum after all other allocations provided for in this Section 16
have been tentatively made as if this Section 16(d)(ii) were not in
this Agreement. This Section 16(d)(ii) is intended to comply with the
“qualified income offset” requirement of Treasury Regulations Section
1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.
	 
	 	(iii)	 	Gross Income Allocation. If any Member has a deficit
Capital Account at the end of any taxable year which is in excess of the sum of
(i) the amount such Member is obligated to restore, if any, 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 Treasury
Regulations Section 1.704-2(g)(1) and 1.704-2(i)(5), 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 16(d)(iii) shall be made only if and to the extent that a
Member would have a deficit Capital Account in excess of such sum after all
other allocations provided for in this Section 16 have been tentatively made as
if Section 16(d)(ii) and this Section 16(d)(iii) were not in
this Agreement.
	 
	 	(iv)	 	Nonrecourse Deductions. Nonrecourse Deductions shall
be allocated to the Members ratably in accordance with such Member’s LLC Units
as set forth on Schedule B of this Agreement.
	 
	 	(v)	 	Member Nonrecourse Deductions. Member Nonrecourse
Deductions for any taxable period shall be allocated to the Member who bears
the economic risk of loss with respect to the liability to which such Member
Nonrecourse Deductions are attributable in accordance with Treasury Regulations
Section 1.704-2(i)(1).
	 
	 	(vi)	 	Ameliorative Allocations. Any special allocations of
income or gain pursuant to Sections 16(d)(ii) or 16(d)(iii)
hereof shall be taken into account in computing subsequent allocations pursuant
to Section 16(c) and this Section 16(d)(vi), so that the net
amount of any items so allocated and all other items allocated to each Member
shall, to the extent possible, be equal to the net amount that would have been
allocated to each Member if such allocations pursuant to Sections
16(d)(ii) or 16(d)(iii) had not occurred.

- 20 -

 

     (e) Income Tax Allocations. For income tax purposes, each item of income, gain, loss
and deduction of the Company shall be allocated among the Members in the same manner as the
corresponding items of Profits and Losses and specially allocated items are allocated for Capital
Account purposes; provided, that in the case of any asset the Book Value of which differs
from its adjusted tax basis for U.S. federal income tax purposes, income, gain, loss and deduction
with respect to such asset shall be allocated solely for income tax purposes in accordance with the
principles of Code Section 704(b) and 704(c) so as to take into account the difference between Book
Value and adjusted tax basis using the “remedial method” pursuant to Treasury Regulations Section
1.704-3(d).

     (f) Tax Matters Member. For so long as the Initial Member is a Principal Member, the
Initial Member shall be the “tax matters partner” within the meaning of Section 6231(a)(7) of the
Code (the “Tax Matters Member”). If the Initial Member ceases to be a Principal Member,
Members owning at least a majority of the LLC Units shall be entitled to appoint a new Tax Matters
Member to replace the Initial Member. The Tax Matters Member shall determine (a) the appropriate
treatment of each item of income, gain, loss, deduction and credit of the Company on its Tax
returns, (b) the accounting methods and conventions under the Tax Laws of the United States, the
several states and other relevant jurisdictions applicable to the treatment of any such item and
(c) any other method or procedure related to the preparation of such Tax returns. The Tax Matters
Member shall have all of the rights, duties, powers and obligations provided for in Sections 6221
through 6232 of the Code. All elections required or permitted to be made by the Company, and all
other Tax decisions and determinations relating to U.S. federal, state or local Tax matters of the
Company, shall be made by the Tax Matters Member. Tax audits, controversies and litigations shall
be conducted under the direction of the Tax Matters Member. The Tax Matters Member shall, upon
request of the Minority Member, provide the Minority Member with information in respect of any of
the foregoing and shall use its reasonable best efforts to keep the Minority Member apprised of any
material developments on matters in respect of which the Minority Member has requested to be kept
so apprised.

     (g) Tax Withholding. To the extent the Company is required by Law to withhold or to
make Tax payments on behalf of or with respect to any Member (“Tax Advances”), the Company
may withhold such amounts and make such Tax payments as so required. All Tax Advances made on
behalf of a Member shall be repaid by reducing the amount of the current or next succeeding
distribution or distributions which would otherwise have been made to such Member or, if such
distributions are not sufficient for that purpose, by so reducing the proceeds of liquidation
otherwise payable to such Member. If a distribution to a Member is actually reduced as a result of
a Tax Advance, for all other purposes of this Agreement such Member shall be treated as having
received the amount of the distribution that is reduced by the Tax Advance. Each Member hereby
agrees to indemnify and hold harmless the Company and the other Members from and against any
liability (including, without limitation, any liability for Taxes, penalties, additions to Tax or
interest) with respect to income attributable to or distributions or other payments to such Member.

Section 17. Distributions.

     (a) Subject to subsections (b), (c) and (d) of this Section 17, distributions shall be
made to the Members at such times and in such aggregate amounts as may be determined by the

- 21 -

 

Board from time to time. Distributions after the date hereof shall be made pro rata to the
Members in accordance with their respective LLC Units as reflected on Schedule B of this
Agreement; provided, that neither (i) the special distribution of the proceeds of the
Minority Member’s contribution of capital to the Company on or about the date hereof in exchange
for the first issuance to it of LLC Units contemplated by the Subscription Agreement nor (ii) the
special distribution of the proceeds of the Management Member’s contribution of capital to the
Company on or after the date hereof in exchange for the first issuance to it of LLC Units
contemplated by the Management Subscription (as defined in the Subscription Agreement) shall be
made pro rata to the Members but rather shall be made exclusively to the Initial Member as a
reimbursement of capital expenditures to EFH (indirectly through the Initial Member) as described
in Treasury Regulation § 1.707-4(d), and neither the Minority Member nor the Management Member
shall have any rights to participation in such special distributions (the “Proceeds
Distributions”); provided further, that each Ordinary Course Dividend (as
defined below) shall be distributed to Members and former Members holding LLC Units at any time
during the applicable quarterly period in respect of which such Ordinary Course Dividend is
calculated, pro rata to such Members based on (1) the number of days in such period that such
Member held LLC Units relative to the total number of dates in such period and (2) such Members’
respective ownership share of LLC Units as a percentage of the total outstanding LLC Units held by
all such Members on each such day. The Company shall cause each of the Proceeds Distributions to
be made promptly on the date that the Company receives the funds therefor from the Minority Member
or the Management Member, as applicable.

     (b) Subject to subsection (d) of this Section 17, the Company shall make quarterly
distributions to the Members equal to the net income of the Company or such greater amount as is
permitted by Section 17(d)(ii) (“Ordinary Course Dividends”).

     (c) Subject to subsection (d) of this Section 17, the Company shall distribute all of
the proceeds of any issuance of LLC Units, unless otherwise directed by the Members;
provided that, each of the Proceeds Distributions shall be distributed as set forth in
Section 17(a) unless otherwise directed by the Initial Member.

     (d) Notwithstanding any other provision contained in this Agreement,

	 	(i)	 	the Company shall not make any distribution to the Members on
account of its interest in the Company if such distribution would violate the
Act or other applicable law;
	 
	 	(ii)	 	other than any distributions made pursuant to Section
17(c) (including, for greater certainty, the Proceeds Distributions), the
Company shall not make any distribution to the Members to the extent that the
amount of such proposed distribution, plus the sum of all prior distributions
made at any time following the first business day after October 10, 2007 (the
“Reference Date”), other than any distribution made pursuant to
Section 17(c) (including, for greater certainty, the Proceeds
Distributions), by the Company to the Members, exceeds the cumulative net
income of the Company (determined in accordance with GAAP) for the period
beginning on the Reference Date to the date of such proposed distribution;

- 22 -

 

	 	 	 	provided, however, that the restriction on distributions set
forth in this Section 17(d)(ii) shall cease to apply and shall be of
no further force or effect on and after January 1, 2013;
	 
	 	(iii)	 	the Company shall defer making any distribution to the Members
so long as and to the extent that such distribution would cause the
debt-to-equity ratio of the Company for regulatory purposes of the Company to
be above the debt-to-equity ratio established from time to time by the Public
Utility Commission of Texas for ratemaking purposes;
	 
	 	(iv)	 	other than in respect of the Proceeds Distributions, the
Company shall not distribute any amounts to the Members to the extent that the
Board determines in good faith that it is necessary to retain such amounts to
meet expected future requirements of the Company; and
	 
	 	(v)	 	other than in respect of the Proceeds Distributions, the
Independent Directors, acting by majority vote, or, at any time prior to a
Trigger Event, any Minority Member Director, shall have the authority to
prevent the Company from making any distribution if they determine that it is
in the best interests of the Company to retain such amounts to meet expected
future requirements of the Company (including continuing compliance with the
debt-to-equity ratio described above in subsection (d)(iii) of this Section
17).

     (e) Subsections (a) through (d) of this Section 17 constitute the Company’s
“Dividend Policy.”

Section 18. Books and Records.

     The Board shall keep or cause to be kept complete and accurate books of account and records
with respect to the Company’s business. The books of the Company shall at all times be maintained
by the Company. The Members who hold in excess of 5% of the then-outstanding LLC Units and their
duly authorized representatives shall have the right to examine the Company books, records and
documents during normal business hours. The Company, and the Board on behalf of the Company, shall
have the right, pursuant to Section 18-305(c) of the Act, to keep confidential from any Member
certain information as the Board deems necessary or appropriate.

Section 19. Reports; Member Information.

     (a) On such date as may be agreed by the Initial Member and the Company, but in no event later
than (i) five (5) days with respect to quarterly statements and (ii) ten (10) days with respect to
annual statements prior to the date on which the EFH Group (a) is required by law or any
contractual obligation or regulatory commitment to file consolidated financial statements with the
SEC or deliver consolidated financial statements to any other Person (which filing or delivery date
shall be communicated to the Company at least 40 days in advance of the Company’s obligation to
deliver the same) or (b) expects to file consolidated financial statements with the SEC or deliver
consolidated financial statements to any other Person in connection with an offering of securities
(which filing or delivery date shall be communicated to the Company at

- 23 -

 

least 40 days in advance of the Company’s obligation to deliver the same), the Board shall
cause to be prepared all annual audited or quarterly unaudited financial statements, as applicable,
and disclosures and certifications required under this Agreement or necessary for such information
to be filed or delivered, along with any other information reasonably requested by the Initial
Member for inclusion in the EFH Group’s consolidated financial statements or SEC filings. Copies
of all such financial statements shall promptly be forwarded to the Minority Member.

     (b) As soon as reasonably practicable after the end of each taxable year but not later than
two hundred and seventy (270) days after the end of each taxable year, the Company shall send to
each Member a copy of U.S. Internal Revenue Service Schedule K-1, and any comparable statements
required by applicable state or local income tax Law, with respect to such taxable 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. The Company shall
bear the cost of the preparation and filing of its Tax returns with respect to the Company and its
Subsidiaries, but shall not bear any additional costs related primarily to any specific Member.

     (c) Upon request of the Company, each Member agrees to furnish the Company with all
information concerning itself and, the case of the Minority Member, Minority Member Parent (or the
ultimate U.S. taxpayer(s) invested in Minority Member Parent, in the event that neither Minority
Member nor Minority Member Parent is a U.S. federal income taxpayer), and their respective
directors and officers as may be required to be disclosed by applicable law, regulation or written
orders from any Governmental Authority or reasonably necessary in connection with any statement,
filing, notice or application made by or on behalf of the Company or any of its Subsidiaries to any
third party and/or any Governmental Authority.

Section 20. Other Business.

     To the extent permitted by law and subject to Section 10(i), any Member and any
Affiliate of a Member (or a direct or indirect shareholder of any such Affiliate or such
shareholder’s Affiliates) (other than Members receiving LLC Units directly or indirectly by virtue
of participation in an equity incentive or other employee benefit plan of the Company or any of its
Subsidiaries or Affiliates, including without limitation through participation in the Management
Member) may engage in or possess an interest in other business ventures (unconnected with the
Company) of every kind and description, independently or with others, and the pursuit of any such
investment or venture, even if competitive with the business of the Company and its Subsidiaries,
shall not be deemed wrongful or improper. The Company shall not have any rights in or to such
independent ventures or the income or profits therefrom by virtue of this Agreement.

     No Member, Director or Affiliate of the foregoing (or any direct or indirect shareholder of
any such Affiliate or such shareholder’s Affiliates) (other than Members receiving LLC Units
directly or indirectly by virtue of participation in an equity incentive or other employee benefit
plan of the Company or any of its Subsidiaries or Affiliates, including without limitation through
participation in the Management Member) shall be obligated to present any particular investment or
business opportunity to the Company even if such opportunity is of a character that, if presented
to the Company, could be pursued by the Company, and any Member, Director or

- 24 -

 

Affiliate of the foregoing (or any direct or indirect shareholder of any such Affiliate or
such shareholder’s Affiliates) (other than Members receiving LLC Units directly or indirectly by
virtue of participation in an equity incentive or other employee benefit plan of the Company or any
of its Subsidiaries or Affiliates including without limitation through participation in the
Management Member) shall have the right to pursue for its own account (individually or as a partner
or a fiduciary) or to recommend to any other Person any such investment opportunity.

Section 21. Exculpation and Indemnification.

     (a) To the fullest extent permitted by law, no Covered Person shall be liable to the Company
or any other Person that is a party to or is otherwise bound by this Agreement for any loss, damage
or claim incurred by reason of any act or omission performed or omitted by such Covered Person in
good faith on behalf of the Company and in a manner reasonably believed to be within the scope of
the authority conferred on such Covered Person by this Agreement, except that a Covered Person
shall be liable for any such loss, damage or claim incurred by reason of such Covered Person’s
fraud, gross negligence or willful misconduct.

     (b) To the fullest extent permitted by applicable law, an Indemnified Person shall be entitled
to indemnification from the Company for any loss, damage or claim incurred by such Indemnified
Person by reason of any act or omission performed or omitted by such Indemnified Person in good
faith on behalf of the Company and in a manner reasonably believed to be within the scope of the
authority conferred on such Indemnified Person by this Agreement, except that no Indemnified Person
shall be entitled to be indemnified in respect of any loss, damage or claim incurred by such
Indemnified Person by reason of such Indemnified Person’s fraud, gross negligence or willful
misconduct with respect to such acts or omissions; provided, however, that any
indemnity under this Section 21 by the Company shall be provided out of and to the extent
of Company assets only, and no Member shall have any personal liability on account thereof.

     (c) To the fullest extent permitted by applicable law, expenses (including reasonable legal
fees) incurred by an Indemnified Person defending any claim, demand, action, suit or proceeding
shall, from time to time, be advanced by the Company prior to the final disposition of such claim,
demand, action, suit or proceeding upon receipt by the Company of an undertaking by or on behalf of
the Indemnified Person to repay such amount if it shall be determined that the Indemnified Person
is not entitled to be indemnified as authorized in this Section 21.

     (d) An Indemnified Person shall be fully protected in relying in good faith upon the records
of the Company and upon such information, opinions, reports or statements presented to the Company
by any Person as to matters the Indemnified Person reasonably believes are within such other
Person’s professional or expert competence and who has been selected with reasonable care by or on
behalf of the Company, including information, opinions, reports or statements as to the value and
amount of the assets, liabilities, or any other facts pertinent to the existence and amount of
assets from which distributions to the Members might properly be paid.

     (e) To the extent that, at law or in equity, an Indemnified Person has duties (including
fiduciary duties) and liabilities relating thereto to the Company or to any other Indemnified
Person, an Indemnified Person acting under this Agreement shall not be liable to the Company or to
any other Indemnified Person for its good faith reliance on the provisions of this Agreement or

- 25 -

 

any approval or authorization granted by the Company or any other Indemnified Person. The
provisions of this Agreement, to the extent that they restrict or eliminate the duties and
liabilities of an Indemnified Person otherwise existing at law or in equity, are agreed by the
Members to replace such other duties and liabilities of such Indemnified Person.

     (f) The foregoing provisions of this Section 21 shall survive any termination of this
Agreement.

Section 22. Assignments.

     (a) Subject to compliance with this Section 22(a) and any transfer restrictions,
requirements or commitments of a Member in any stockholders, investor rights, sale participation or
registration rights agreement(s) to which such Member is a party relating to its LLC Units, a
Member may assign in whole or in part its LLC Units. The transferee shall be admitted to the
Company as a Member of the Company upon its execution of a counterpart signature page to this
Agreement and a joinder agreement or other instrument reasonably acceptable to the Company
signifying its agreement to be bound by the terms and conditions of this Agreement and assume the
obligations of the transferor Member hereunder in respect of the transferred LLC Units. If the
Member transfers all of its remaining LLC Units in the Company pursuant to this Section
22(a), the admission of the transferee shall be deemed effective immediately prior to the
transfer and, immediately following such admission, the transferor Member shall cease to be a
member of the Company. Notwithstanding anything in this Agreement to the contrary, any successor
to a Member by merger or consolidation in compliance with this Agreement shall, without further
act, be a Member hereunder, and such merger or consolidation shall not constitute an assignment for
purposes of this Agreement and the Company shall continue without dissolution.

     (b) Any attempted assignment or transfer of LLC Units in contravention of this Section
22 shall, to the fullest extent permitted by law, be null and void, and the Company shall not
be bound by or recognize any such attempted Transfer on the books and records of the Company.

     (c) The rights of each of the Initial Member and the Minority Member to designate Director(s)
to the Board shall be assignable (in whole but not in part) without the consent of the Company, the
Board or any other Members, in connection with a valid Transfer by that Member of all or a
substantial portion of its LLC Units in accordance with the provisions of this Agreement and the
Investor Rights Agreement where such transferee (and any designees) also agrees in a writing
reasonably acceptable to the Company to be bound by the terms and conditions hereof and thereof
applicable to the Initial Member or Minority Member, as applicable (or in the case of a designee,
pursuant to the Management Agreement).

     (d) The rights of the Minority Member to designate the Board Observer shall be personal to
such Member and not assignable (whether in connection with a Transfer of LLC Units or otherwise) by
such Member without the prior written consent of the Company, the Initial Member and its Permitted
Transferees.

- 26 -

 

Section 23. Resignation.

     So long as (i) any Obligation is outstanding, and (ii) the Initial Member (together with its
Permitted Transferees) own a majority of the LLC Units, the Initial Member may not resign;
provided, that nothing in this Section 23 shall limit the Initial Member’s rights
under Section 22 to assign its LLC Units.

Section 24. Dissolution.

     (a) The Company shall be dissolved, and its affairs shall be wound up upon the first to occur
of the following: (i) the termination of the legal existence of the last remaining member of the
Company or the occurrence of any other event which terminates the continued membership of the last
remaining member of the Company in the Company unless the Company is continued without dissolution
in a manner permitted by this Agreement or the Act or (ii) the entry of a decree of judicial
dissolution of the Company under Section 18 802 of the Act. Upon the occurrence of any event that
causes the last remaining member of the Company to cease to be a member of the Company (other than
upon continuation of the Company without dissolution upon an assignment by the last remaining
Member of all of its LLC Units and the admission of a transferee pursuant to Section
22(a)), to the fullest extent permitted by law, the personal representative of such member is
hereby authorized to, and shall, within 90 days after the occurrence of the event that terminated
the continued membership of such member in the Company, agree in writing (A) to continue the
Company and (B) to the admission of the personal representative or its nominee or designee, as the
case may be, as a substitute member of the Company, effective as of the occurrence of the event
that terminated the continued membership of the last remaining member of the Company.

     (b) Notwithstanding any other provision of this Agreement, the Bankruptcy of a Member shall
not cause such Member to cease to be a member of the Company and upon the occurrence of such an
event, the Company shall continue without dissolution.

     (c) Notwithstanding any other provision of this Agreement, each Member waives any right it
might have to agree in writing to dissolve the Company upon the Bankruptcy of the Member, or the
occurrence of an event that causes the Member to cease to be a member of the Company.

     (d) In the event of dissolution, the Company shall conduct only such activities as are
necessary to wind up its affairs (including the sale of the assets of the Company in an orderly
manner), and the assets of the Company shall be applied in the manner, and in the order of
priority, set forth in Section 18 804 of the Act.

     (e) The Company shall terminate when (i) 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 Members in the manner provided for in this Agreement and (ii) the
Certificate of Formation shall have been canceled in the manner required by the Act.

-27-

 

Section 25. Waiver of Partition; Nature of Interest.

     Except as otherwise expressly provided in this Agreement, to the fullest extent permitted by
law, each Member hereby irrevocably waives any right or power that such Member might have to cause
the Company or any of its assets to be partitioned, to cause the appointment of a receiver for all
or any portion of the assets of the Company, to compel any sale of all or any portion of the assets
of the Company pursuant to any applicable law or to file a complaint or to institute any proceeding
at law or in equity to cause the dissolution, liquidation, winding up or termination of the
Company. No Member shall have any ownership interest in any specific assets of the Company, and no
Member shall have the status of a creditor with respect to any distribution pursuant to Section
17 hereof. The interest of each Member in the Company is personal property.

Section 26. Benefits of Agreement; No Third Party Rights.

     The provisions of this Section shall apply notwithstanding any provision of this Agreement to
the contrary. None of the provisions of this Agreement shall be for the benefit of or enforceable
by any creditor of the Company or by any creditor of any Member. Nothing in this Agreement shall
be deemed to create any right in any Person (other than Covered Persons and Indemnified Persons)
not a party hereto, and this Agreement shall not be construed in any respect to be a contract in
whole or in part for the benefit of any third Person (except as provided in Section 20,
Section 21 and Section 29).

Section 27. Severability of Provisions.

     Each provision of this Agreement shall be considered severable and if for any reason any
provision or provisions herein are determined to be invalid, unenforceable or illegal under any
existing or future law, such invalidity, unenforceability or illegality shall not impair the
operation of or affect those portions of this Agreement which are valid, enforceable and legal.

Section 28. Entire Agreement.

     This Agreement constitutes the entire agreement of the parties with respect to the subject
matter hereof.

Section 29. Binding Agreement.

     Notwithstanding any other provision of this Agreement, each Member agrees that this Agreement
constitutes a legal, valid and binding agreement of the Member, and is enforceable against the
Member by the Independent Directors, in accordance with its terms. In addition, the Independent
Directors shall be intended beneficiaries of this Agreement.

Section 30. Governing Law; Judicial Proceedings.

     This Agreement shall be governed by and construed under the laws of the State of Delaware
(without regard to conflict of laws principles), all rights and remedies being governed by said
laws. In any judicial proceeding involving any dispute, controversy or claim arising out of or
relating to this Agreement, each of the Members unconditionally accepts the non-exclusive

-28-

 

jurisdiction and venue of any United States District Court located in the State of Delaware, or of
the Court of Chancery of the State of Delaware, and the appellate courts to which orders and
judgments thereof may be appealed. In any such judicial proceeding, the Members agree that in
addition to any method for the service of process permitted or required by such courts, to the
fullest extent permitted by Law, service of process may be made by delivery provided pursuant to
the directions in Section 33. EACH OF THE MEMBERS HEREBY WAIVES TRIAL BY JURY IN ANY JUDICIAL
PROCEEDING INVOLVING ANY DISPUTE, CONTROVERSY OR CLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT
OR RELATING TO THE COMPANY OR ITS OPERATIONS.

Section 31. Amendments.

     Subject to Section 10(i), this Agreement may be modified, altered, supplemented or
amended only pursuant to a written agreement executed and delivered by the Members holding
collectively a majority of the then aggregate outstanding LLC Units; provided, that: (A)
the prior written consent of any Member shall be required in respect of any such proposed
modification, alteration, supplement or amendment that would have a material disproportionate
adverse impact on that Member (in its capacity as a Member) as compared to the other Members (in
their capacity as Members); and (B) for so long as the Minority Member (together with its Permitted
Transferees) holds at least 1% of the outstanding LLC Units, the prior written consent of the
Minority Member shall be required to modify, alter, supplement or amend any of the following
provisions if such modification, alteration, supplement or amendment would have any adverse impact
on the Minority Member, its Affiliates or any direct or indirect shareholders thereof: Sections
10(a), 10(i), 16, 17 and 22. Any amendment or revision to Schedule B hereto or to the
Company’s records that is made by an Officer solely to reflect information regarding Members shall
not be considered an amendment to this Agreement and shall not require any Board or Member
approval.

Section 32. Counterparts.

     This Agreement may be executed in any number of counterparts, each of which shall be deemed an
original of this Agreement and all of which together shall constitute one and the same instrument.

Section 33. Notices.

     (a) Except as expressly set forth to the contrary in this Agreement, all notices, requests or
consents provided for or required to be given hereunder shall be in writing and shall be deemed to
be duly given if personally delivered; telecopied and confirmed; mailed by certified mail, return
receipt requested; or sent via nationally recognized overnight delivery
service with proof of receipt maintained (i) in the case of the Company, to the Company at its
address in Section 2, (ii) in the case of a Member, to such Member at its address as listed
on Schedule B attached hereto and (iii) in the case of either of the foregoing, at such
other address as may be designated by written notice to the other party.

     (b) Any such notice shall, if delivered personally, be deemed received upon delivery; shall,
if delivered by telecopy, be deemed received on the first business day following

-29-

 

confirmation;
shall, if delivered by nationally recognized overnight delivery service, be deemed received the
first business day after being sent; and shall, if delivered by mail, be deemed received upon the
earlier of actual receipt thereof or five business days after the date of deposit in the United
States mail.

     (c) Whenever any notice is required to be given by Law or this Agreement, a written waiver
thereof, signed by the Person entitled to notice, whether before or after the time stated therein,
shall be deemed equivalent to the giving of such notice.

     “Adjusted Capital Account Balance” means, with respect to each Member, the balance in

     SECTION 4. Allocation of Liability. (a) With respect to the portion of the Oncor
Holdings Separate Tax Liability and the Oncor Separate Tax Liability that is not described in
Section 6(b) of this Agreement and relates to income of Oncor and Oncor Holdings that is included
in the Tax Returns of the EFH Group, Minority Investor or the members of Management Investor as

 10

 

     (i) Other than with respect to the Applicable Tax Year described in clause (ii), for
each Applicable Tax Year, Oncor shall pay to each of EFH, Minority Investor and Management
Investor an amount equal to their Sharing Percentages of such Oncor Separate Tax Liability
and shall indemnify and hold each EFH Indemnified Party, Minority Investor and Management
Investor harmless for an amount equal to their Sharing Percentage of such Oncor Separate Tax

     (ii) Solely with respect to the Applicable Taxable Year commencing January 1, 2008,
Oncor shall pay (A) to Minority Investor, an amount equal to (x) [19.75]% multiplied by a
fraction equal to (366-X)/366 where X = the number of days prior to the admission of
Minority Investor as a party to this Agreement multiplied by (y) such Oncor Separate Tax
Liability for such year, (B) to Management Investor, an amount equal to (x) [.22]%
multiplied by a fraction equal to (366-X)/366 where X = the number of days prior to the
admission of Management Investor as a party to this Agreement multiplied by (y) such Oncor
Separate Tax Liability for such year, and (C) to EFH, an amount equal to such Oncor Separate
Tax Liability minus the amounts paid in clauses (A) and (B), and shall indemnify and hold
each of Minority Investor, Management Investor and each EFH Indemnified Party harmless for
an amount equal to the amounts described in clauses (A), (B) and (C) respectively.

     (iii) Oncor Holdings shall pay to EFH the Oncor Holdings Excess Separate Tax Liability

 11

 

provisions of the Code to be carried back to one or more prior Applicable Taxable Years, the
Oncor Holdings Excess Separate Tax Liability or Oncor Separate Tax Liability, as appropriate, shall
be recomputed for each such prior Applicable Taxable Year to take into account such carryback.
EFH, Minority Investor and Management Investor shall make an adjusting payment to Oncor Holdings or
Oncor, as appropriate, promptly after the date when the benefit of such carryback would have been
realized by a member of the Oncor Distributions Group, or by Oncor, if it had filed its own Tax
Return reflecting such carryback, or as soon as such adjustment can practicably be calculated, if
later. Such adjusting payment shall be in the amount required such that, for each such prior
Applicable Taxable Year, the payments made by Oncor Holdings or Oncor pursuant to the terms of this
Agreement less the payments made by EFH, Minority Investor and Management Investor to Oncor
Holdings or Oncor, respectively, pursuant to the terms of this Agreement, or, with respect to
Applicable Taxable Years that ended prior to the Effective Date, such payments that are actually
made in accordance with prior practice, equals the Oncor Holdings Excess Separate Tax Liability or
the Oncor Separate Tax Liability, as appropriate, for such taxable year. Any payment required to
be made to Oncor under this Section 4(b) will be made by EFH, Minority Investor and Management
Investor in accordance with their Sharing Percentages for the Applicable Taxable Year to which the
realized loss or credit would be permitted to be carried back.

          (c) For purposes of this Agreement, except as set forth in Sections 4(b) and 8, all payments
that would have been due by one Party to another Party pursuant to this Agreement with respect to
Applicable Taxable Years that ended prior to the Effective Date shall be treated as if they were
made on a timely basis.

 12

 

          (d) (i) For the avoidance of doubt, notwithstanding anything in this Agreement, to the extent
required by law, Oncor shall remain jointly and severally liable for Taxes of the EFH Group for
Applicable Taxable Years ending on or prior to the Effective Date as a successor to Oncor Electric
Delivery Company.

          (ii) EFH shall indemnify and hold Oncor harmless for any Taxes of the EFH Group (other than
Taxes of Oncor or Oncor Electric Delivery Company as a predecessor to Oncor) that are imposed on
Oncor under Treasury Regulations Section 1.1502-6 or, if any, applicable similar provisions of
state or local law for any Applicable Taxable Year during which Oncor Electric Delivery Company was
a member of a combined or consolidated group of which EFH was the parent.

     SECTION 5. Calculations.

          (a) EFH shall determine the Oncor Holdings Excess Separate Tax Liability and Oncor Separate
Tax Liability (i) in accordance with this Agreement and EFH Group’s method of federal income tax
allocation (in the manner set forth in Exhibit A), in a manner that is consistent with Sections
1.1502 33(d) and 1.1552 1 of the Treasury Regulations or, in the case of Taxes other than United
States federal income taxes, any other permissible allocation methodology and (ii) consistent with
general Tax accounting principles and past practice.

          (b) For each Tax Return filed by EFH, EFH shall provide Oncor Holdings or Oncor, as
appropriate, in good faith, within 3 Business Days prior to the due date of any payment required to
be made by Oncor Holdings or Oncor pursuant to Sections 4(a) and 6, with a calculation of the
amount (if any) of any (i) Oncor Holdings Excess Separate Tax Liability and Oncor Separate Tax
Liability, (ii) estimated Oncor Holdings Excess Separate Tax Liability and estimated Oncor Separate
Tax Liability and/or (iii) True-up Payment (for purposes of Section 6).

13

 

Such calculation shall provide sufficient detail to permit Oncor Holdings or Oncor, as
appropriate, to reasonably understand such calculation. Oncor Holdings or Oncor, as appropriate,
shall have the right to review and comment on such calculation. If EFH and Oncor Holdings or
Oncor, as appropriate, cannot agree on the calculations prepared under this Section 5, then such
dispute shall be resolved pursuant to Section 12. For the avoidance of doubt, any calculations
provided by EFH in accordance with this Section 5 will apply for purposes of this Agreement pending
the resolution of any such dispute pursuant to Section 12.

     SECTION 6. Settlement.

          (a) All amounts due pursuant to Section 4(a) hereof shall be paid at least 5 Business Days
before each Estimated Tax Installment Date and on each such date such paid amount shall equal the
amount of any estimated Oncor Holdings Excess Separate Tax Liability and Oncor Separate Tax
Liability that Oncor Holdings or Oncor, respectively, would have otherwise been required to pay to
a Taxing Authority on such Estimated Tax Installment Date (for the avoidance of doubt, treating
Oncor Holdings and Oncor as corporations). Any amounts due pursuant to this Section 6(a) shall be
calculated in accordance with the method described in Section 6655(d) of the Code, as appropriate,
unless all the Parties to this Agreement agree to an alternative method.

          (b) (i) Oncor Holdings and Oncor shall pay to the applicable Taxing Authority the portion of
the Oncor Holdings Excess Separate Tax Liability and Oncor Separate Tax Liability, respectively,
for which they are directly liable, on or before the date such payment is required to be paid to a
Tax Authority.

          (ii) Oncor Holdings and Oncor shall pay to EFH, the portion of the Oncor Holdings Excess
Separate Tax Liability and Oncor Separate Tax Liability, respectively, for

14

 

which EFH is, but Oncor Holdings, Oncor, Minority Investor or Management Investor, is not,
liable to pay on behalf of Oncor Holdings or Oncor, respectively, including, without limitation any
liability relating to the Texas Franchise Tax, Chapter 171 of the Texas Tax Code (or any succeeding
tax), at least 2 Business Days prior to the date such payment is required to be made by EFH to a
Tax Authority.

          (c) If, for any taxable year, the payments made by Oncor Holdings or Oncor pursuant to
Sections 6(a) and (b) are different from the Oncor Holdings Excess Separate Tax Liability or the
Oncor Separate Tax Liability, respectively, for such taxable year, then EFH, Minority Investor,
Management Investor, Oncor Holdings or Oncor, as the case may be, shall make an adjusting payment
two Business Days prior to the filing of the applicable Tax Return for such taxable year (the
“True-up Payment Date”) in the amount required such that payments made by Oncor Holdings
and Oncor for such taxable year (taking into account the adjustments, if any, pursuant to Section
4(b) and this Section 6(c)) equal the Oncor Holdings Excess Separate Tax Liability and the Oncor
Separate Tax Liability, respectively, for such taxable year (such difference, the “True-up
Payment”). Any payment required to be made to Oncor under this Section 6(c) which relate to Taxes
described in Section 6(a) shall be made by EFH, Minority Investor and Management Investor in
accordance with their Sharing Percentages for the taxable year to which the True-up Payment
relates, and any payment that relates to any Taxes described in Section 6(b)(ii) shall be made by
EFH.

          (d) If any payments are required to be made by Management Investor to Oncor under this
Agreement (including, without limitation, any True-up Payment), Oncor may, in its sole discretion,
elect to collect payment of such amounts due by offsetting against such amounts any subsequent
payments by it to the Management Investor under this Agreement. Nothing in

15

 

this Section 6(d) shall reduce or modify the obligations of the Management Investor to make
payments at the time and in the manner specified in this Agreement.

     SECTION 7. Tax Proceedings. EFH shall have exclusive control of any Tax Proceeding
with respect to any member of the EFH Group or the Oncor Holdings Group; provided
that EFH shall not settle any such Tax Proceeding without the consent of Oncor Holdings or
Oncor (such consent not to be unreasonably conditioned, delayed or withheld) if such settlement
would increase the relevant Oncor Holdings Excess Separate Tax Liability or Oncor Separate Tax
Liability, respectively; and provided further that EFH shall conduct a
particular Tax Proceeding at the direction of Oncor Holdings or Oncor if such Tax Proceeding would
affect only the Tax Liability of a member of the Oncor Distributions Group or the Tax Liability of
Oncor, respectively.

     SECTION 8. Recomputation. If, for any Applicable Taxable Year, the Tax liability of
any member of the EFH Group or Oncor Holdings Group is redetermined as a result of a Final
Determination, whether as a result of a refund (including a refund resulting from a carryback), an
Internal Revenue Service adjustment or otherwise, the payment obligations of the Parties pursuant
to the terms of this Agreement, or, with respect to Applicable Taxable Years that ended prior to
the date of this Agreement, the payment obligations as determined in accordance with prior
practice, shall be redetermined by EFH in a reasonable manner, and either EFH, Minority Investor,
Management Investor, Oncor Holdings and/or Oncor, as the case may be, shall make an adjusting
payment to the other in the amount required such that, for such taxable year (and for each other
Applicable Taxable Year), the payments made by Oncor Holdings and Oncor equals the Oncor Holdings
Excess Separate Tax Liability and the Oncor Separate Tax Liability, respectively (taking into
account the correlative effects of such redetermination). Any payment

16

 

required to be made to (or by) Oncor under this Section 8 which relates to Taxes described in
Section 6(a) with respect to the Oncor Separate Tax Liability shall be made by (or to) EFH,
Minority Investor and Management Investor in accordance with their Sharing Percentages for the
Applicable Tax Year with respect to which the Tax liability of Oncor is redetermined as a result of
such Final Determination, and any payment that relates to Taxes described in Section 6(b)(ii) shall
be made by EFH.

     SECTION 9. Prohibited Actions. Oncor Holdings and Oncor agree not to take any
actions that would increase the Tax liability (other than as a result of Oncor Holdings Excess
Separate Tax Liabilities and Oncor Separate Tax Liabilities) of any member of the EFH Group for any
Applicable Taxable Year (the “Additional EFH Group Tax Liability”). In the event Oncor
Holdings or Oncor takes, or fails to take, any action that causes an Additional EFH Group Tax
Liability, then Oncor Holdings and/or Oncor, as appropriate, shall be liable to indemnify and hold
harmless the appropriate EFH Indemnified Parties to the extent such Additional EFH Group Tax
Liability does not increase the Oncor Holdings Excess Separate Tax Liability or the Oncor Separate
Tax Liability. Oncor Holdings and/or Oncor shall pay to EFH at least 2 Business Days before each
Estimated Tax Installment Date and True-up Payment Date the amount that EFH is required to pay to a
Taxing Authority on or before such Estimated Tax Installment Date and True-up Payment Date due to
the applicable Additional EFH Group Tax Liability. For the avoidance of doubt, Oncor Holdings and
Oncor shall together not be liable to indemnify the EFH Indemnified Parties pursuant to this
Section 9 for an amount that exceeds, in the aggregate, the Additional EFH Group Tax Liability.

     SECTION 10. Applicability. This Agreement shall apply to any Tax Return in respect
of any member of the EFH Group or the Oncor Holdings Group that is due (after taking into

17

 

account any legally permissible extensions) following the Effective Date and to any Tax Return
in respect of any member of the EFH Group or the Oncor Holdings Group, for so long as the
applicable statute of limitations remains open (the “Applicable Tax Returns”).

     SECTION 11. Assistance and Cooperation. EFH, Minority Investor, Management Investor,
Oncor Holdings and/or Oncor, as appropriate, shall and shall cause their respective Affiliates to
(i) cooperate fully in preparing for any Tax Proceedings with respect to any Applicable Tax Return,
(ii) make available to the others as reasonably requested all information, records, and documents
relating to any Applicable Tax Return, (iii) provide timely notice to the others of any pending or
threatened tax audits or assessments with respect to any Applicable Taxable Year and (iv) furnish
the others with copies of all correspondence received from any Taxing Authority in connection with
any Tax Proceeding or information request with respect to any Applicable Taxable Year.

     SECTION 12. Disputes.

          (a) Negotiation by Officers. In the event of a controversy, dispute or claim arising out of,
in connection with, or in relation to the negotiation, interpretation, performance, nonperformance,
validity or breach of this Agreement or otherwise arising out of, or in any way related to this
Agreement, including, without limitation, any claim based on contract, tort, statute or
constitution (collectively, “Agreement Disputes”), officers appointed by the chief
executive officers of the relevant parties shall negotiate in good faith for a reasonable period of
time to settle such Agreement Dispute. If that Agreement Dispute cannot be settled through direct
discussions by the 20th calendar day (or as such date may be extended by the mutual agreement of
the parties) after such officers first discuss the matter, then the Agreement Dispute will be
resolved as set forth below:

18

 

          (b) Mediation. If any Agreement Dispute is not resolved pursuant to Section 12(a), the
Parties agree to attempt to settle the dispute in an amicable manner by mediation with a jointly
appointed Tax Professional. Each party to the mediation shall bear its own expenses with respect
to the mediation and the parties shall share equally the fees and expenses of the mediator. Any
demand for initiation of mediation of a dispute must be given in writing and must set forth in
reasonable detail the nature of the dispute. Mediation may be concluded by any party thereto at
any time. The mediator shall not have the authority to render any award or otherwise bind the
parties to any action. Each party to the mediation shall bear its own expenses with respect to the
mediation and the parties shall share equally the fees and expenses of the mediator. Any mediation
conducted pursuant hereto shall be conducted at a site in Dallas, Texas selected by the mediator
that is reasonably convenient to the parties. The mediator shall be disqualified as a witness,
consultant, expert or counsel for any party with respect to the dispute of any related matter. All
information and documents disclosed in mediation by any Person shall remain private and
confidential to the disclosing Person and may not be disclosed by any Person outside the mediation.
No privilege or right with respect to any information or document disclosed in mediation shall be
waived or lost by such disclosure.

          (c) Arbitration. In the event that any Agreement Dispute is not settled pursuant to the
mediation procedures set forth above, such Agreement Dispute shall be resolved by final and binding
arbitration conducted pursuant to the American Arbitration Association Commercial Arbitration
Rules, Title 9 of the U.S. Code and the Texas Arbitration Act. Notwithstanding anything to the
contrary contained herein, the parties agree that the American Arbitration Association shall not
administer any Agreement Dispute. Judgment on the award rendered by the arbitrators may be entered
in any federal court in the Northern District of Texas, Dallas

19

 

Division or a state court in Dallas County, Texas. Any challenge to any arbitration award
shall be filed in and each party agrees not to remove or transfer such action from a federal court
in the Northern District of Texas, Dallas Division or a state court in Dallas County, Texas.
Notwithstanding the foregoing, in the event the Minority Investor is a party to an Agreement
Dispute, any challenge to any arbitration award shall in the first instance be filed in and each
party agrees not to remove or transfer such action from the United States District Court for the
Southern District of New York or any state court setting in the City of New York, Borough of
Manhattan.

          (1) Any party desiring to commence arbitration shall send a written notice (an
“Arbitration Notice”) to the other party describing the dispute and setting forth
the matters to be resolved by the arbitration. Within ten Business Days after the date of
such notice (an “Arbitration Notice Period”), the other party may, if such party
does not agree with the description or statement of matters to be resolved, send an
Arbitration Notice to the other party describing the dispute and setting forth the matters
to be resolved by the arbitration. Within ten Business Days after the end of the
Arbitration Notice Period, the parties shall, if they can agree, select an arbitrator to
resolve the dispute. In the event that the parties have not selected an arbitrator within
ten Business Days of the end of the Arbitration Notice Period, then the dispute shall be
resolved by majority decision of a panel of three arbitrators, one selected by each party
and the third selected by the two party-selected arbitrators, which the parties agree to
instruct such arbitrators to make.

          (2) The place of arbitration shall be Dallas, Texas.

          (3) The arbitrator(s) shall have no authority to award punitive damages or any other
damages not measured by the prevailing party’s actual losses, and may not, in

20

 

any event, make any ruling, finding or award that does not conform to the terms and
conditions of this Agreement.

          (4) At any time after the commencement of arbitration hereunder, any party may make an
application to the arbitrator(s) seeking injunctive relief to maintain the status quo until
such time as the arbitration award is rendered or the controversy is otherwise resolved.
Either party may also apply to any court having jurisdiction hereof at any time to seek
injunctive relief until such time as the arbitration award is rendered or the controversy is
otherwise resolved.

          (5) Except as required by Law, or with the consent of both parties involved in an
arbitration, no party hereto shall disclose or disseminate any information relating to an
Agreement Dispute or to the dispute resolution proceedings called for hereby except for
disclosure to those of its officers, employees, accountants, attorneys and agents whose
duties reasonably require them to have access to such information.

          (6) The parties in the arbitration shall share equally the costs and expenses of the
arbitration. Each party shall otherwise bear its own fees and expenses.

     SECTION 13. Interest. Payments pursuant to this Agreement shall bear interest (i) if
such payments are not made within the period prescribed in this Agreement (the “Payment
Period”), for the period from and including the date immediately following the last date of the
Payment Period through and including the date of payment, and (ii) if such payments are made in
accordance with the resolution of a dispute pursuant to Section 12, for the period from and
including the date on which notice was first given by the disputing party through and including the
date of such resolution; in each case at a per annum rate equal to the lesser of (i) the prime rate
as published in the Wall Street Journal on the last day of such payment period, plus two

21

 

percent (2%) and (ii) the maximum lawful amount of interest then permitted to be charged.
Such interest shall be payable at the same time as the payment to which it relates and shall be
calculated on the basis of a year of 365 days and the actual number of days for which it is due.

     SECTION 14. Tax Treatment of Certain Entities. As of the date of this Agreement,
Oncor Holdings is treated as a disregarded entity for U.S. federal income tax purposes and Oncor is
treated as a partnership for U.S. federal income tax purposes.

     SECTION 15. Jointly Owned Entities. EFH, Oncor Holdings and Oncor represent that
they will not own a direct or indirect interest in a Jointly Owned Entity.

     SECTION 16. Amendment. This Agreement may be amended, modified or supplemented only
by a written agreement signed by the Parties hereto.

     SECTION 17. Assignment. This Agreement shall not be assignable, in whole or in part,
directly or indirectly, by any party without the prior written consent of the other Parties, and
any attempt to assign any rights or obligations arising under this Agreement without such consent
shall be void.

     SECTION 18. Successors and Assigns. The terms of this Agreement shall be binding
upon, inure to the benefit of and be enforceable by the Parties and their respective successors and
permitted assigns.

     SECTION 19. Governing Law. This Agreement and all claims arising out of or based
upon this Agreement or relating to the subject matter hereof shall be governed by and construed in
accordance with the laws of the State of Texas without giving effect to any choice or conflict of
laws provision or rule that would cause the application of the laws of any other jurisdiction.

EXHIBIT A

          (a) Applicable Taxable Years Ending after the Effective Date. For purposes of
computing the Oncor Holdings Separate Tax Liability and the Oncor Separate Tax Liability with
respect to U.S. federal consolidated income taxes or other taxes shown on combined returns for
Applicable Taxable Years ending after the Effective Date, the Tax liability of the Oncor Group and
the Oncor Holdings Group (each referred to in this exhibit as a “Member”), calculated as if such
group had filed a consolidated or combined Tax Return (assuming each was treated as a corporation
for tax purposes) for itself and each Member of the group separate and apart from the EFH Group,
shall be determined by the following formula (with each step further described below):

1. Regular tax liability

2. Add: alternative minimum tax

3. Subtract: credits against tax

4. Subtotal: tax liability due from Member

5. Subtract: prior payments from Member

6. Total: payment due from Member

          (1) Step 1: Regular Tax Liability. Each Member shall be charged or credited for its
regular tax liability. The regular tax liability is equal to the taxable income of the
Member determined as if such Member were a corporation multiplied by 35%. A Member has a
net operating loss for any year in which the taxable income of the Member is negative.

          (2) Step 2: Alternative Minimum Tax. Each Member shall be charged for its alternative
minimum tax liability or credited for its minimum tax credit utilized. The alternative
minimum tax liability or minimum tax credit utilized by a Member is calculated as follows:

     (a) Step 2A: Tentative Minimum Tax. Calculate the tentative minimum tax of
each Member. The tentative minimum tax of a Member is equal to the alternative
minimum taxable income or loss of the Member multiplied by 20%. The alternative
minimum taxable income or loss of a Member shall be computed on the basis of the
Member’s taxable income as determined in Step 1 above adjusted to take into account
(i) the adjustments and preferences provided in Code Sections 56 (excluding the Code
Section 56(g) adjustment relating to ACE), 57, and 58, and (ii) the portion of the
consolidated ACE adjustment under Proposed Treasury Regulation Section
1.1502-55(b)(3) attributable to such Member.

     (b) Step 2B: Alternative Minimum Tax Liability. Calculate the alternative
minimum tax liability of each Member. The alternative minimum tax liability of a
Member is equal to the difference of (but not less than zero) the (i) tentative
minimum tax of the Member (calculated as provided in step 2A above) and (ii) the
regular tax liability of the Member (calculated as provided in step 1

25

 

above) adjusted as provided in Code Section 55(c) (relating to foreign tax credits
and other adjustments).

          (3) Step 3: Credits Against Tax. Each Member is credited for any credits against tax
reflected on the balance sheet of the Member on the Effective Date or properly allocable to
the Member following the Effective Date.

          (4) Step 4: Subtotal — Tax Liability Due From Member. The total of the amounts in
steps 1 through 3 represents the amount due from each Member to EFH, or in the case of
Oncor, to EFH, Minority Investor and Management Investor in accordance with Section 4 of
this Agreement.

          (5) Step 5: Prior Payments. Each Member shall be credited for all prior payments to
EFH, or in the case of Oncor, to EFH, Minority Investor and Management Investor, for the
relevant period with respect to the relevant tax.

          (6) Step 6: Payment Due. The difference between the amount calculated in step 4 and
the credit in step 5 shall represent the amount due from the Member to EFH, or in the case
of Oncor, to EFH, Minority Investor and Management Investor.

          (b) Applicable Taxable Years Ending prior to the Effective Date. For purposes of
computing the Oncor Holdings Separate Tax Liability and the Oncor Separate Tax Liability with
respect to U.S. federal consolidated income taxes or other taxes shown on combined returns for
Applicable Taxable Years ending prior to the Effective Date, the Tax liability of each Member shall
be determined by the following formula (with each step further described below):

1. Regular tax liability

2. Add: alternative minimum tax

3. Subtract: credits against tax

4. Subtotal: tax liability due from (to) Member

5. Subtract: prior payments from (to) Member

6. Total: payment due from (to) Member

          (1) Step 1: Regular Tax Liability. Each Member shall be charged or credited for its
regular tax liability. The regular tax liability of a Member is calculated as follows:

     (a) Consolidated Taxable Income. If the Consolidated Group has zero or
positive consolidated taxable income for the year (as determined under Treasury
Regulation Section 1.1502-11(a)), the regular tax liability of each Member is equal
to the taxable income of the Member multiplied by 35%.

     (b) Consolidated Net Operating Loss. If the Consolidated Group has a
consolidated net operating loss for the year (as defined in Treasury Regulation
Section 1.1502-21(e)),

26

 

     (1) the regular tax liability of any Member having positive taxable
income is equal to the taxable income of the Member multiplied by 35%, and

     (2) the regular tax liability of any Member having negative taxable
income (i.e., a net operating loss) is a credit equal to the aggregate
regular tax liability of all Members having positive taxable income
multiplied by a fraction the numerator of which is net operating loss of the
Member and the denominator of which is the total net operating loss of all
Members having a net operating loss.

     (c) Taxable Income of a Member

     (1) In General. The taxable income of a Member shall be determined in
accordance with Treasury Regulation Section 1.1552-1(a)(1)(ii) (excluding
the last sentence of such subdivision which causes a Member’s taxable income
to be zero if the calculation results in an excess of deductions over gross
income). A Member has a net operating loss for any year in which the
taxable income of the Member is negative.

     (2) Allocation of Consolidated Net Operating Loss Deduction. For
purposes of computing the taxable income of a Member for any year, the
portion of the consolidated net operating loss deduction for such year (if
any) attributable to such Member shall be an amount equal to the
consolidated net operating loss deduction for such year (“loss
absorption year”) multiplied by a fraction, the numerator of which is
the Member’s net operating loss for the year in which the net operating loss
carryover or carryback arises (“loss origination year”), and the
denominator of which is the total of the net operating losses of all Members
for the loss origination year to the extent such losses are included in the
net operating loss carryover or carryback utilized in the loss absorption
year.

     (d) Full Allocation. The sum of the regular tax liabilities of all Members
shall be equal to the consolidated regular tax liability of the group as defined in
Proposed Treasury Regulation Section 1.1502-2(a)(1)(i).

     (2) Step 2: Alternative Minimum Tax. Each Member shall be charged for its alternative
minimum tax liability or credited for its minimum tax credit utilized. The alternative
minimum tax liability or minimum tax credit utilized by a Member is calculated as follows:

     (a) Step 2A: Tentative Minimum Tax. Calculate the tentative minimum tax of
each Member. The tentative minimum tax of a Member is equal to the alternative
minimum taxable income or loss of the Member multiplied by 20%, minus the portion of
the consolidated alternative minimum tax foreign tax credit attributable to the
Member. The alternative minimum taxable income or loss of a Member shall be
computed on the basis of the Member’s taxable income

27

 

as determined in Step 1 above adjusted to take into account (i) the adjustments and
preferences provided in Code Sections 56 (excluding the Code Section 56(g)
adjustment relating to ACE), 57, and 58, (ii) the portion of the consolidated ACE
adjustment under Proposed Treasury Regulation Section 1.1502-55(b)(3) attributable
to such Member, and (iii) the portion of the consolidated ATNOL deduction under
Proposed Treasury Regulation Section 1.1502-55(b)(4) attributable to such Member.
The sum of the tentative minimum tax of all Members shall be equal to the
consolidated AMT of the group as defined in Proposed Treasury Regulation Section
1.1502-55(a)(1).

     (b) Step 2B: Separate Tax Liability. Calculate the separate tax liability of
each Member. The separate tax liability of a Member is equal to the greater of the
(i) tentative minimum tax of the Member (calculated as provided in step 2A above)
and (ii) the regular tax liability of the Member (calculated as provided in step 1
above) adjusted as provided in Code Section 55(c) (relating to foreign tax credits
and other adjustments).

     (c) Step 2C: Separate Alternative Minimum Tax. Calculate for each Member the
separate alternative minimum tax. The separate alternative minimum tax of a Member
is equal to the excess (if any) of the regular tax liability of the Member as
calculated in step 2B(ii) over the separate tax liability of the Member as
calculated in step 2B.

     (d) Step 2D: Consolidated AMT Difference. Calculate for the consolidated AMT
difference. The consolidated AMT difference is equal to (i) the sum of the
tentative minimum tax amounts for all Members of the Consolidated Group, minus (ii)
the sum of the separate tax liability amounts for all Members of the Consolidated
Group.

     (e) Step 2E: Allocated Consolidated AMT Difference. Calculate the allocated
consolidated AMT difference for each Member. The allocated consolidated AMT
difference of a Member is equal to the consolidated AMT difference calculated in
step 2D, multiplied by a fraction, the numerator of which is the separate
alternative minimum tax of the Member calculated in step 2C, and the denominator of
which is the sum of the separate alternative minimum tax amounts for all Members as
calculated in step 2C.

     (f) Step 2F: Alternative Minimum Tax Liability or Minimum Tax Credit Utilized.
Calculate the alternative minimum tax for each Member. The alternative minimum tax
of a Member is the sum of (i) the separate alternative minimum tax of the Member
calculated in step 2C and (ii) the allocated consolidated AMT of the Member
calculated in step 2E. A positive sum represents alternative minimum tax liability
incurred (minimum tax credit generated), and a negative sum represents minimum tax
credit utilized (regular tax liability reduced).

28

 

          (3) Step 3: Credits Against Tax. Each Member is credited for the portion of the
consolidated credits against tax under sections 21 through 52 of the Code attributable to
the Member. The portion of any particular credit attributable to any Member shall be based
on a fraction, the numerator of which is the Member’s gross credit on a stand alone basis
(i.e., without reduction for any limitation based on the Member’s tax liability or other
factors), and the denominator of which is the total gross credit of all Members).

          (4) Step 4: Subtotal — Tax Liability Due From (To) Member. The sum of the charges
(positive amounts) and credits (negative amounts) in steps 1 through 3 represents the amount
due from each Member to EFH (if the net amount is a positive amount) or due from EFH to the
Member (if the net amount is a negative amount).

          (5) Step 5: Prior Payments. Each Member shall be credited for all prior payments to
EFH, and charged for all prior payments by EFH to the Member, with respect to the
Consolidated Tax Liability for the taxable year.

          (6) Step 6: Payment Due. The subtotal calculated in step 4 as adjusted for the
charges or credits in step 5 shall represent the amount due from the Member to EFH (if
positive) or from EFH to the Member (if negative) with respect to the adjustments to the
Consolidated Tax Liability or tax items of Members for the taxable year.

          (c) Utilization of Carryback Items. Treasury Regulation 1.1502-21 or any successor
provision shall govern the ordering and priority of utilization of any carryback item, including
any Ventures Carryback Item, to any return filed by the Consolidated Group.

          (d) Treatment of EFH. For purposes of the allocation of taxes under this agreement,
EFH is a Member of the Consolidated Group with respect to its tax items, and the aggregate payments
due from or to EFH shall take into account payments due to or from EFH in its role as a Member of
the group, such that the net amount of all payments from and to EFH is zero.

     2. The execution and delivery of, and performance by the Company of its obligations under,
each Transaction Document have been duly authorized by all necessary limited liability company
action on the part of the Company. Each Transaction Document executed by the Company has been duly
executed and delivered by the Company and constitutes the valid and binding agreement of the
Company, enforceable against the Company in accordance with its terms.

     3. The execution and delivery of, and performance by the Company of its agreements in, each
Transaction Document does not violate (i) the Company’s Amended and Restated Limited Liability
Company Agreement, (ii) any law, statute, rule or regulation, or (iii) any judgment, decree, or
order of any court or any other agency of government known to us that is applicable to the Company
