annuity contracts described in Code Section 403(b) and eligible plans under

substituting in lieu thereof the following:

	 	(a)	 	In General. Notwithstanding the preceding provisions of this
Article VII, a Participant or Beneficiary shall have the right, in accordance
with the provisions of this Section 7.05, to direct the Trustee as to the
investment of (i) his Salary Reduction Contribution Account, (ii) any amounts
held in his Employer Contribution Account, and (iii) any amounts in his
Employee Contribution Account either in the ESOP portion of the Plan, or in the
Non-ESOP portion of the Plan which consists of various investment media
comprising a Diversified Fund. In addition, a Participant or Beneficiary shall
have the right, as of any Valuation Date, in accordance with the provisions of
this Section 7.05, to direct the Trustee to reinvest, in the Non-ESOP portion
of the Plan, any amount invested in Company Stock in the ESOP portion of the
Plan. Such investment directions shall be made in accordance with procedures

3

 

	 	 	 	established by the Committee and the requirements of Department of Labor
Regulations § 2550.404c-1(b)(2)(i)(A), or any successor thereto. Should a
Participant or Beneficiary fail to provide the Trustee with the investment
directions described herein as to any Salary Reduction Contribution, or
rollover contribution, or other amounts (other than Discretionary
Contributions) deposited in his Employer Contribution Account, or amounts
deposited in his Employee Contribution Account, if any, such contribution or
amount deposited shall be invested in the Diversified Fund which constitutes
a balanced fund of equity and fixed income, as selected by the Trustee. The
Trustee may decline to implement instructions by a Participant or
Beneficiary which (i) would result in a prohibited transaction described in
Code Section 4975 or ERISA Section 406 and which would generate income that
would be taxable to the Plan, or (ii) are described in Department of Labor
Regulations § 2550.404c-1(d)(2)(ii), or any successor thereto.

            15. Section 7.05 is further amended by adding a new subsection 7.05(f) at the end of said
Section as follows:

	 	(f)	 	TXU Stock Fund. Notwithstanding the foregoing provisions of
this Section 7.05, a Participant for whom amounts are invested in the TXU Stock
Fund provided for under Section 3.09(a) may direct that all or any portion of
such amounts be invested in a Diversified Fund or in Company Stock in
accordance with the procedures established by the Committee; however, no
additional amounts may be invested in the TXU Stock Fund.

            IN WITNESS WHEREOF, the Company has caused this AMENDMENT NO. FOUR TO THE ATMOS ENERGY
CORPORATION RETIREMENT SAVINGS PLAN AND TRUST EFFECTIVE JANUARY 1, 1999 to be executed in its name
on its behalf 2004, effective as of the dates set forth herein.

ARTICLE II

REGISTRATION RIGHTS

     Section 2.1 Shelf Registration.

          (a) Shelf Registration. As soon as practicable following the Closing of the
acquisition of the Purchased Units pursuant to the terms of the Purchase Agreement, but in any
event within 90 days of the Closing, Crosstex shall prepare and file a Shelf Registration
Statement. Crosstex shall use its commercially reasonable efforts to cause the Shelf Registration
Statement to become effective no later than 180 days after the date of the Closing. A Shelf
Registration Statement filed pursuant to this Section 2.1(a) shall be on such appropriate
registration form of the Commission as shall be selected by Crosstex; provided, however, that if a
prospectus supplement will be used in connection with the marketing of an Underwritten Offering
from the Shelf Registration Statement and the Managing Underwriter at any time shall notify
Crosstex in writing that, in the sole judgment of such Managing Underwriter, inclusion of detailed
information to be used in such prospectus supplement is of material importance to the success of
the Underwritten Offering of such Registrable Securities, Crosstex shall use its commercially
reasonable efforts to include such information in the prospectus. Crosstex will use its
commercially reasonable efforts to cause the Shelf Registration Statement filed pursuant to this
Section 2.1(a) to be continuously effective under the Securities Act until the earlier of
(i) all Registrable Securities covered by the Shelf Registration Statement have been distributed in
the manner set forth and as contemplated in the Shelf Registration Statement or (ii) there are no

3

 

longer any Registrable Securities outstanding (the “Effectiveness Period”). The Shelf
Registration Statement when declared effective (including the documents incorporated therein by
reference) will comply as to form in all material respects with all applicable requirements of the
Securities Act and the Exchange Act and 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 not misleading. If the Shelf Registration Statement is not declared effective within 210
days after Closing, then the Purchasers shall be entitled to a payment (with respect to each of
such Purchaser’s Purchased Units), as liquidated damages and not as a penalty, of 0.25% of the
Purchase Price per 30-day period for the first sixty (60) days following the 210th day after
Closing, with such payment amount increasing by an additional 0.25% of the Purchase Price per
30-day period for each subsequent 60 days, up to a maximum of 1.0% of the Purchase Price per 30-day
period (the “Liquidated Damages”), until such time as the Shelf Registration Statement is
declared effective or there are no longer any Registrable Securities outstanding. The Liquidated
Damages shall be paid to each Purchaser in cash within ten (10) Business Days of the end of such
30-day period. The Purchasers’ rights (and any transferee’s rights pursuant to Section 2.10) under
this Section 2.1 shall terminate when such Registrable Securities become eligible for resale under
Rule 144(k) (or any similar provision then in force under the Securities Act).

          (b) Delay Rights. Notwithstanding anything to the contrary contained herein, Crosstex
may, upon written notice to any Selling Holder whose Registrable Securities are included in the
Shelf Registration Statement, suspend such Selling Holder’s use of any prospectus which is a part
of the Shelf Registration Statement (in which event the Selling Holder shall discontinue sales of
the Registrable Securities pursuant to the Shelf Registration Statement) if (i) Crosstex is
pursuing an acquisition, merger, reorganization, disposition or other similar transaction and
Crosstex determines in good faith that Crosstex’s ability to pursue or consummate such a
transaction would be materially and adversely affected by any required disclosure of such
transaction in the Shelf Registration Statement or (ii) Crosstex has experienced some other
material non-public event the disclosure of which at such time, in the good faith judgment of
Crosstex, would materially and adversely affect Crosstex; however, in no event shall any delay
pursuant hereto exceed sixty (60) days in any one hundred-eighty (180) day period or ninety (90)
days in any twelve-month period. Upon disclosure of such information or the termination of the
condition described above, Crosstex shall provide prompt notice to the Selling Holders whose
Registrable Securities are included in the Shelf Registration Statement, and shall promptly
terminate any suspension of sales it has put into effect and shall take such other actions to
permit registered sales of Registrable Securities as contemplated in this Agreement.

     Section 2.2 Piggyback Registration.

          (a) Participation. After the Purchased Units have converted into Common Units if
Crosstex at any time proposes to file a prospectus supplement to an effective Shelf Registration
Statement with respect to an Underwritten Offering of Common Units for its own account or to
register any Common Units for its own account for sale to the public in an
Underwritten Offering other than (x) a registration relating solely to employee benefit plans,
(y) a registration relating solely to a Rule 145 transaction, or (z) a registration on any
registration form which does not permit secondary sales, does not include substantially the same
information as would be required to be included in a registration statement covering the sale of
Registrable

4

 

Securities or would require that Crosstex effectuate a post-effective amendment to such
registration statement to permit such Registrable Securities to be covered by the registration
statement, then, as soon as practicable following the engagement of counsel to Crosstex to prepare
the documents to be used in connection with an Underwritten Offering, Crosstex shall give notice of
such proposed Underwritten Offering to the Holders, and such notice shall offer the Holders the
opportunity to include in such Underwritten Offering such number of Registrable Securities (the
“Included Registrable Securities”) as each such Holder may request in writing (a
“Piggyback Registration”); provided, however, that Crosstex shall not be
required to offer such opportunity to Holders if (i) the Holders do not offer a minimum of
$5,000,000 of Purchased Units (determined by multiplying the number of Purchased Units offered by
the average of the closing price for Common Units for the ten (10) trading days preceding the date
of such notice) or (ii) Crosstex has been advised by the Managing Underwriter that the inclusion of
Registrable Securities for sale for the benefit of the Holders will have an adverse effect on the
price, timing or distribution of the Common Units. The notice required to be provided in this
Section 2.2(a) to Holders shall be provided on a Business Day pursuant to Section
3.1 hereof and receipt of such notice shall be confirmed by Holder. Holder shall then have two
business days to request inclusion of Registrable Securities in the Underwritten Offering. If no
request for inclusion from a Holder is received within the specified time, such Holder shall have
no further right to participate in such Piggyback Registration. If, at any time after giving
written notice of its intention to undertake an Underwritten Offering and prior to the closing of
such Underwritten Offering, Crosstex shall determine for any reason not to undertake or to delay
such Underwritten Offering, Crosstex may, at its election, give written notice of such
determination to the Selling Holders and, (x) in the case of a determination not to undertake such
Underwritten Offering, shall be relieved of its obligation to sell any Included Registrable
Securities in connection with such terminated Underwritten Offering, and (y) in the case of a
determination to delay such Underwritten Offering, shall be permitted to delay offering any
Included Registrable Securities for the same period as the delay in the Underwritten Offering. Any
Selling Holder shall have the right to withdraw such Selling Holder’s request for inclusion of such
Selling Holder’s Registrable Securities in such offering by giving written notice to Crosstex of
such withdrawal up to and including the time of pricing of such offering. No Holders shall be
entitled to participate in any such Underwritten Offering under this Section 2.2(a) unless all
Holders participating therein hold at least fifteen million ($15,000,000) of Purchased Units
(determined by multiplying the number of Purchased Units offered by the average of the closing
price for Common Units for the ten (10) trading days preceding the date of such notice).

          (b) Priority of Piggyback Registration. If the Managing Underwriter or Underwriters
of any proposed Underwritten Offering of Common Units included in a Piggyback Registration advises
Crosstex that the total amount of Common Units which the Selling Holders and any other Persons
intend to include in such offering exceeds the number which can be sold in such offering without
being likely to have an adverse effect on the price, timing or distribution of the Common Units
offered or the market for the Common Units, then the Common Units to be included in such
Underwritten Offering shall include the number of Registrable Securities that such Managing
Underwriter or Underwriters advises Crosstex can be sold without having such
adverse effect, with such number to be allocated pro rata among the Selling
Holders and any other Persons who have been or are granted registration rights on or after the date
of this Agreement (“Other Holders”) who have requested participation in the Piggyback
Registration (based, for each such Selling Holder or Other Holder, on the percentage derived by
dividing (A)

5

 

the number of Registrable Securities proposed to be sold by such Selling Holder or
such Other Holder in such offering; by (B) the aggregate number of Common Units proposed to be sold
by all Selling Holders and all Other Holders in the Piggyback Registration.

     Section 2.3 Underwritten Offering.

          (a) S-3 Registration. In the event that a Selling Holder (together with any Affiliate
that is a Selling Holder) elects to dispose of Registrable Securities under the Shelf Registration
Statement pursuant to an Underwritten Offering of at least fifteen million ($15,000,000) of Common
Units, Crosstex shall, at the request of such Selling Holder, enter into an underwriting agreement
in customary form with the Managing Underwriter or Underwriters, which shall include, among other
provisions, indemnities to the effect and to the extent provided in Section 2.8, and shall
take all such other reasonable actions as are requested by the Managing Underwriter in order to
expedite or facilitate the disposition of the Registrable Securities; provided, however, that
Crosstex management will not be required to participate in a roadshow or similar marketing effort.

          (b) General Procedures. In connection with any Underwritten Offering (i) under
Section 2.2 of this Agreement, Crosstex shall be entitled to select the Managing
Underwriter or Underwriters, and (ii) under Section 2.3 of this Agreement, the Selling
Holders shall be entitled to select the Managing Underwriter or Underwriters. In connection with
an Underwritten Offering under Section 2.2 or Section 2.3 hereof, each Selling
Holder and Crosstex shall be obligated to enter into an underwriting agreement which contains such
representations, covenants, indemnities and other rights and obligations as are customary in
underwriting agreements for firm commitment offerings of securities. No Selling Holder may
participate in such Underwritten Offering unless such Selling Holder agrees to sell its Registrable
Securities on the basis provided in such underwriting agreement and completes and executes all
questionnaires, powers of attorney, indemnities and other documents reasonably required under the
terms of such underwriting agreement. Each Selling Holder may, at its option, require that any or
all of the representations and warranties by, and the other agreements on the part of, Crosstex to
and for the benefit of such underwriters also be made to and for such Selling Holder’s benefit and
that any or all of the conditions precedent to the obligations of such underwriters under such
underwriting agreement also be conditions precedent to its obligations. No Selling Holder shall be
required to make any representations or warranties to or agreements with Crosstex or the
underwriters other than representations, warranties or agreements regarding such Selling Holder and
its ownership of the securities being registered on its behalf and its intended method of
distribution and any other representation required by law. If any Selling Holder disapproves of
the terms of an underwriting, such Selling Holder may elect to withdraw therefrom by notice to
Crosstex and the Managing Underwriter; provided, however, that such withdrawal must
be made prior to the time in the penultimate sentence of Section 2.2(a) hereof to
be effective. No such withdrawal or abandonment shall affect Crosstex’s obligation to pay
Registration Expenses.

     Section 2.4 Sale Procedures. In connection with its obligations contained in Sections
2.1, 2.2 and 2.3, Crosstex will, as expeditiously as possible:

6

 

          (a) prepare and file with the Commission such amendments and supplements to the Shelf
Registration Statement and the prospectus used in connection therewith as may be necessary to keep
the Shelf Registration Statement effective for the Effectiveness Period and as may be necessary to
comply with the provisions of the Securities Act with respect to the disposition of all securities
covered by the Shelf Registration Statement;

          (b) furnish to each Selling Holder (i) as far in advance as reasonably practicable before
filing the Shelf Registration Statement or any other registration statement contemplated by this
Agreement or any supplement or amendment thereto, upon request, copies of reasonably complete
drafts of all such documents proposed to be filed (including exhibits and each document
incorporated by reference therein to the extent then required by the rules and regulations of the
Commission), and provide each such Selling Holder the opportunity to object to any information
pertaining to such Selling Holder and its plan of distribution that is contained therein and make
the corrections reasonably requested by such Selling Holder with respect to such information prior
to filing the Shelf Registration Statement or such other registration statement and the prospectus
included therein or any supplement or amendment thereto, and (ii) such number of copies of the
Shelf Registration Statement or such other registration statement and the prospectus included
therein and any supplements and amendments thereto as such Persons may reasonably request in order
to facilitate the public sale or other disposition of the Registrable Securities covered by such
Shelf Registration Statement or other registration statement;

          (c) if applicable, use its commercially reasonable efforts to register or qualify the
Registrable Securities covered by the Shelf Registration Statement or any other registration
statement contemplated by this Agreement under the securities or blue sky laws of such
jurisdictions as the Selling Holders or, in the case of an Underwritten Offering, the Managing
Underwriter, shall reasonably request, provided that Crosstex will not be required to qualify
generally to transact business in any jurisdiction where it is not then required to so qualify or
to take any action which would subject it to general service of process in any such jurisdiction
where it is not then so subject;

          (d) promptly notify each Selling Holder and each underwriter, at any time when a prospectus
relating thereto is required to be delivered under the Securities Act, of (i) the filing of the
Shelf Registration Statement or any other registration statement contemplated by this Agreement or
any prospectus included therein or any amendment or supplement thereto, and, with respect to such
Shelf Registration Statement or any other registration statement or any post-effective amendment
thereto, when the same has become effective; and (ii) any written comments from the Commission with
respect to any filing referred to in clause (i) and any written request by the Commission for
amendments or supplements to the Shelf Registration
Statement or any other registration statement or any prospectus or prospectus supplement
thereto;

          (e) immediately notify each Selling Holder and each underwriter, at any time when a prospectus
relating thereto is required to be delivered under the Securities Act, of (i) the happening of any
event as a result of which the prospectus contained in the Shelf Registration Statement or any
other registration statement contemplated by this Agreement or any supplemental amendment thereto,
includes an untrue statement of a material fact or omits to state

7

 

any material fact required to be
stated therein or necessary to make the statements therein not misleading in the light of the
circumstances then existing; (ii) the issuance or threat of issuance by the Commission of any stop
order suspending the effectiveness of the Shelf Registration Statement or any other registration
statement contemplated by this Agreement, or the initiation of any proceedings for that purpose; or
(iii) the receipt by Crosstex of any notification with respect to the suspension of the
qualification of any Registrable Securities for sale under the applicable securities or blue sky
laws of any jurisdiction. Following the provision of such notice, Crosstex agrees to as promptly
as practicable amend or supplement the prospectus or prospectus supplement or take other
appropriate action so that the prospectus or prospectus supplement does not include 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 not misleading in the light of the circumstances then
existing and to take such other action as is necessary to remove a stop order, suspension, threat
thereof or proceedings related thereto;

          (f) Upon request and subject to appropriate confidentiality obligations, furnish to each
Selling Holder copies of any and all transmittal letters or other correspondence with the
Commission or any other governmental agency or self-regulatory body or other body having
jurisdiction (including any domestic or foreign securities exchange) relating to such offering of
Registrable Securities;

          (g) in the case of an Underwritten Offering, furnish upon request, (i) an opinion of counsel
for Crosstex, dated the effective date of the applicable registration statement or the date of any
amendment or supplement thereto, preliminary or prospectus supplement, and a letter of like kind
dated the date of the closing under the underwriting agreement, and (ii) a “cold comfort” letter,
dated the effective date of the applicable registration statement or the date of any amendment or
supplement thereto, preliminary or prospectus supplement and a letter of like kind dated the date
of the closing under the underwriting agreement, in each case, signed by the independent public
accountants who have certified Crosstex’s financial statements included or incorporated by
reference into the applicable registration statement, and each of the opinion and the “cold
comfort” letter shall be in customary form and covering substantially the same matters with respect
to such registration statement (and the prospectus included therein any supplement thereto) and as
are customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to
the underwriters in Underwritten Offerings of securities, such other matters as such underwriters
may reasonably request;

          (h) otherwise use its commercially reasonable efforts to comply with all applicable rules and
regulations of the Commission, and make available to its security holders, as soon as reasonably
practicable, an earnings statement covering the period of at least 12 months, but not more than 18
months, beginning with the first full calendar month after the effective date
of such registration statement, which earnings statement shall satisfy the provisions of
Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;

          (i) make available to the appropriate representatives of the Managing Underwriter and Selling
Holders access to such information and Crosstex personnel as is reasonable and customary to enable
such parties to establish a due diligence defense under the Securities Act; provided that Crosstex
need not disclose any information to any such

8

 

representative unless and until such representative
has entered into a confidentiality agreement with Crosstex;

          (j) cause all such Registrable Securities registered pursuant to this Agreement to be listed
on each securities exchange or nationally recognized quotation system on which similar securities
issued by Crosstex are then listed;

          (k) use its commercially reasonable efforts to cause the Registrable Securities to be
registered with or approved by such other governmental agencies or authorities as may be necessary
by virtue of the business and operations of Crosstex to enable the Selling Holders to consummate
the disposition of such Registrable Securities;

          (l) provide a transfer agent and registrar for all Registrable Securities covered by such
registration statement not later than the effective date of such registration statement; and

          (m) enter into customary agreements and take such other actions as are reasonably requested by
the Selling Holders or the underwriters, if any, in order to expedite or facilitate the disposition
of such Registrable Securities.

     Each Selling Holder, upon receipt of notice from Crosstex of the happening of any event of the
kind described in subsection (e) of this Section 2.4, shall forthwith discontinue
disposition of the Registrable Securities until such Selling Holder’s receipt of the copies of the
supplemented or amended prospectus contemplated by subsection (e) of this Section 2.4 or
until it is advised in writing by Crosstex that the use of the prospectus may be resumed, and has
received copies of any additional or supplemental filings incorporated by reference in the
prospectus, and, if so directed by Crosstex, such Selling Holder will, or will request the Managing
Underwriter or underwriters, if any, to deliver to Crosstex (at Crosstex’s expense) all copies in
their possession or control, other than permanent file copies then in such Selling Holder’s
possession, of the prospectus and any prospectus supplement covering such Registrable Securities
current at the time of receipt of such notice.

     Section 2.5 Cooperation by Holders. Crosstex shall have no obligation to include in the
Shelf Registration Statement units of a Holder or in a Piggyback Registration units of a Selling
Holder who has failed to timely furnish such information which, in the opinion of counsel to
Crosstex, is reasonably required in order for the registration statement or prospectus supplement,
as applicable, to comply with the Securities Act.

     Section 2.6 Restrictions on Public Sale by Holders of Registrable Securities. Each Holder of Registrable Securities who is included in the Shelf Registration Statement agrees
not to effect any public sale or distribution of the Registrable Securities during the 30 calendar
day period beginning on the date of a prospectus supplement filed with the Commission with respect
to the pricing of an Underwritten Offering, provided that the duration of the foregoing
restrictions shall be no longer than the duration of the shortest restriction generally imposed by
the underwriters on the officers or directors or any other unitholder of Crosstex on whom a
restriction is imposed and provided further that such Selling Holder (together with any Affiliate
that is a Selling Holder) owns at least fifteen million ($15,000,000) of Purchased Units

9

 

(determined by multiplying the number of Purchased Units offered by the average of the closing
price for Common Units for the ten (10) trading days preceding the date of such filing).

     Section 2.7 Expenses.

          (a) Certain Definitions. “Registration Expenses” means all expenses incident
to Crosstex’s performance under or compliance with this Agreement to effect the registration of
Registrable Securities in a Shelf Registration pursuant to Section 2.1, a Piggyback
Registration pursuant to Section 2.2, or an Underwritten Offering pursuant to Section
2.3, and the disposition of such securities, including, without limitation, all registration,
filing, securities exchange listing and NASDAQ National Market fees, all registration, filing,
qualification and other fees and expenses of complying with securities or blue sky laws, fees of
the National Association of Securities Dealers, Inc., transfer taxes and fees of transfer agents
and registrars, all word processing, duplicating and printing expenses, the fees and disbursements
of counsel and independent public accountants for Crosstex, including the expenses of any special
audits or “cold comfort” letters required by or incident to such performance and compliance.
Except as otherwise provided in Section 2.8 hereof, Crosstex shall not be responsible for
legal fees incurred by Holders in connection with the exercise of such Holders’ rights hereunder.
In addition, Crosstex shall not be responsible for any “Selling Expenses,” which means all
underwriting fees, discounts and selling commissions and transfer taxes allocable to the sale of
the Registrable Securities.

          (b) Expenses. Crosstex will pay all reasonable Registration Expenses in connection
with a Piggyback Registration or Underwritten Offering, whether or not any sale is made pursuant to
the Piggyback Registration or Underwritten Offering. Each Selling Holder shall pay all Selling
Expenses in connection with any sale of its Registrable Securities hereunder.

     Section 2.8 Indemnification.

          (a) By Crosstex. In the event of a registration of any Registrable Securities under
the Securities Act pursuant to this Agreement, Crosstex will indemnify and hold harmless each
Selling Holder thereunder, its directors and officers, and each underwriter, pursuant to the
applicable underwriting agreement with such underwriter, of Registrable Securities thereunder and
each Person, if any, who controls such Selling Holder or underwriter within the meaning of the
Securities Act and the Exchange Act, against any losses, claims, damages, expenses or
liabilities (including reasonable attorneys’ fees and expenses) (collectively,
“Losses”), joint or several, to which such Selling Holder or underwriter or controlling
Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such
Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any material fact
contained in the Shelf Registration Statement or any other registration statement contemplated by
this Agreement, any preliminary prospectus or final prospectus contained therein, or any amendment
or supplement thereof, or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the statements therein
(in the case of a prospectus, in light of the circumstances under which they were made) not
misleading, and will reimburse each such Selling Holder, its directors and officers, each such
underwriter and each such controlling Person for any legal or other expenses reasonably incurred by
them in

10

 

connection with investigating or defending any such Loss or actions or proceedings;
provided, however, that Crosstex will not be liable in any such case if and to the
extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission so made in conformity with information furnished by such
Selling Holder, such underwriter or such controlling Person in writing specifically for use in the
Shelf Registration Statement or such other registration statement, or prospectus supplement, as
applicable. Such indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of such Selling Holder or any such director, officer or controlling Person,
and shall survive the transfer of such securities by such Selling Holder.

          (b) By Each Selling Holder. Each Selling Holder agrees severally and not jointly to
indemnify and hold harmless Crosstex, its directors and officers, and each Person, if any, who
controls Crosstex within the meaning of the Securities Act or of the Exchange Act to the same
extent as the foregoing indemnity from Crosstex to the Selling Holders, but only with respect to
information regarding such Selling Holder furnished in writing by or on behalf of such Selling
Holder expressly for inclusion in the Shelf Registration Statement or prospectus supplement
relating to the Registrable Securities, or any amendment or supplement thereto; provided,
however, that the liability of each Selling Holder shall not be greater in amount than the
dollar amount of the proceeds (net of any Selling Expenses) received by such Selling Holder from
the sale of the Registrable Securities giving rise to such indemnification.

          (c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the
commencement of any action, such indemnified party shall, if a claim in respect thereof is to be
made against the indemnifying party hereunder, notify the indemnifying party in writing thereof,
but the omission so to notify the indemnifying party shall not relieve it from any liability which
it may have to any indemnified party other than under this Section 2.8. In any action
brought against any indemnified party, it shall notify the indemnifying party of the commencement
thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall
wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such
indemnified party and, after notice from the indemnifying party to such indemnified party of its
election so to assume and undertake the defense thereof, the indemnifying party shall not be liable
to such indemnified party under this Section 2.8 for any legal expenses subsequently
incurred by such indemnified party in connection with the defense thereof other than reasonable
costs of investigation and of liaison with counsel so selected; provided, however,
that, (i) if the indemnifying party has failed to assume the defense and
employ counsel or (ii) if the defendants in any such action include both the indemnified party
and the indemnifying party and counsel to the indemnified party shall have concluded that there may
be reasonable defenses available to the indemnified party that are different from or additional to
those available to the indemnifying party, or if the interests of the indemnified party reasonably
may be deemed to conflict with the interests of the indemnifying party, then the indemnified party
shall have the right to select a separate counsel and to assume such legal defense and otherwise to
participate in the defense of such action, with the reasonable expenses and fees of such separate
counsel and other reasonable expenses related to such participation to be reimbursed by the
indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no
indemnified party shall settle any action brought against it with respect to which it is entitled
to indemnification hereunder without the consent of the indemnifying party,

11

 

unless the settlement
thereof imposes no liability or obligation on, and includes a complete and unconditional release
from all liability of, the indemnifying party.

          (d) Contribution. If the indemnification provided for in this Section 2.8 is
held by a court or government agency of competent jurisdiction to be unavailable to Crosstex or any
Selling Holder or is insufficient to hold them harmless in respect of any Losses, then each such
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 as between Crosstex on the one
hand and such Selling Holder on the other, in such proportion as is appropriate to reflect the
relative fault of Crosstex on the one hand and of such Selling Holder on the other in connection
with the statements or omissions which resulted in such Losses, as well as any other relevant
equitable considerations; provided, however, that in no event shall such Selling
Holder be required to contribute an aggregate amount in excess of the dollar amount of proceeds
(net of Selling Expenses) received by such Selling Holder from the sale of Registrable Securities
giving rise to such indemnification. The relative fault of Crosstex on the one hand and each
Selling Holder on the other shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged omission to state
a material fact has been made by, or relates to, information supplied by such party, and the
parties’ relative intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The parties hereto agree that it would not be just and equitable if
contributions pursuant to this paragraph were to be determined by pro rata allocation or by any
other method of allocation which does not take account of the equitable considerations referred to
in the first sentence of this paragraph. The amount paid by an indemnified party as a result of
the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal
and other expenses reasonably incurred by such indemnified party in connection with investigating
or defending any Loss which is the subject of this paragraph. 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 is not guilty of such fraudulent misrepresentation.

          (e) Other Indemnification. The provisions of this Section 2.8 shall be in
addition to any other rights to indemnification or contribution which an indemnified party may have
pursuant to law, equity, contract or otherwise.

     Section 2.9 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission
that may permit the sale of the Registrable Securities to the public without registration, Crosstex
agrees to use its commercially reasonable efforts to:

          (a) Make and keep public information regarding Crosstex available, as those terms are
understood and defined in Rule 144 of the Securities Act, at all times from and after the date
hereof;

          (b) File with the Commission in a timely manner all reports and other documents required of
Crosstex under the Securities Act and the Exchange Act at all times from and after the date hereof;
and

12

 

          (c) So long as a Holder owns any Registrable Securities, furnish to such Holder forthwith upon
request a copy of the most recent annual or quarterly report of Crosstex, and such other reports
and documents so filed as such Holder may reasonably request in availing itself of any rule or
regulation of the Commission allowing such Holder to sell any such securities without registration.

     Section 2.10 Transfer or Assignment of Registration Rights. The rights to cause Crosstex
to register Registrable Securities granted to the Purchasers by Crosstex under this Article II may
be transferred or assigned by the Purchasers to one or more transferee(s) or assignee(s) of such
Registrable Securities, who (a) are Affiliates of such Purchaser, or (b) hold Registrable
Securities representing at least fifteen million ($15,000,000) of Registrable Securities determined
as provided in Section 2.2(a). Crosstex shall be given written notice prior to any said
transfer or assignment, stating the name and address of each such transferee and identifying the
securities with respect to which such registration rights are being transferred or assigned, and
each such transferee shall assume in writing responsibility for its obligations of the Purchasers
under this Agreement.

     Section 2.11 Limitation on Subsequent Registration Rights. From and after the date hereof,
Crosstex shall not, without the prior written consent of the Holders of a majority of the
outstanding Registrable Securities, enter into any agreement with any current or future holder of
any securities of Crosstex that would allow such current or future holder to require Crosstex to
include securities in any registration statement filed by Crosstex on a basis that is superior in
any way to the piggyback rights granted to the Purchasers hereunder.

have the right to an injunction or other equitable relief in any court of competent jurisdiction,
enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of
the parties hereto hereby waives any and all defenses it may have on the ground of lack of

by different parties hereto in separate counterparts, each of which counterparts, when so executed

without regard to principles of conflict of laws.

     Section 3.9 Severability of Provisions. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to
the extent of such prohibition or unenforceability without invalidating the remaining provisions
hereof or affecting or impairing the validity or enforceability of such provision in any other
jurisdiction.

     Section 3.10 Entire Agreement. This Agreement, the Purchase Agreement and the
Non-Disclosure Agreement are intended by the parties as a final expression of their agreement and
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 or therein. There are no restrictions,
promises, warranties or undertakings, other than those set forth or referred to herein or therein

understandings between the parties with respect to such subject matter.

15

 

     Section 3.11 Amendment. This Agreement may be amended only by means of a written amendment
signed by Crosstex and the Holders of a majority of the then outstanding Registrable Securities;
provided, however, that no such amendment shall materially and adversely affect the rights of any
Holder hereunder without the consent of such Holder.

     Section 3.12 No Presumption. In the event any claim is made by a party relating to any
