REGISTRATION RIGHTS AGREEMENT

June 17, 2005

Credit Suisse First Boston LLC

  Eleven Madison Avenue

     New York, New York 10010-3629

Dear Sirs:

     PetroQuest Energy, Inc., a Delaware corporation, and PetroQuest Energy, L.L.C., a Louisiana
limited liability company, (each an “Issuer”, and together, the “Issuers”), propose to jointly and
severally issue and sell to Credit Suisse First Boston LLC (the “Initial Purchaser”), upon the
terms set forth in a purchase agreement dated as of June 17, 2005 (the “Purchase Agreement”),
$25,000,000 aggregate principal amount of their 10-3/8% Senior Notes Due 2012 (the “Initial
Securities”) to be unconditionally guaranteed (the “Guaranties”) by the subsidiaries of PetroQuest
Energy, Inc. set forth on Schedule C-1 to the Purchase Agreement (the “Guarantors” and together
with the Issuers, the “Company”). The Initial Securities will be issued as additional securities
pursuant to an Indenture, dated as of May 11, 2005 (the “Indenture”) among the Issuers, the
Guarantors and The Bank of New York Trust Company, N.A. (the “Trustee”). As an inducement to the
Initial Purchaser, the Company agrees with the Initial Purchaser, for the benefit of the holders of
the Initial Securities (including, without limitation, the Initial Purchaser), the Exchange
Securities (as defined below) and the Private Exchange Securities (as defined below) (collectively
the “Holders”), as follows:

     1. Registered Exchange Offer. The Company shall, at its own cost, prepare and, not later
than August 9, 2005, file with the Securities and Exchange Commission (the “Commission”) a
registration statement (the “Exchange Offer Registration Statement”) on an appropriate form under
the Securities Act of 1933, as amended (the “Securities Act”), with respect to a proposed offer
(the “Registered Exchange Offer”) to the Holders of Transfer Restricted Securities (as defined in
Section 6 hereof), who are not prohibited by any law or policy of the Commission from participating
in the Registered Exchange Offer, to issue and deliver to such Holders, in exchange for the Initial
Securities, a like aggregate principal amount of debt securities (the “Exchange Securities”) of the
Issuers issued under the Indenture and identical in all material respects to the Initial Securities
(except for the transfer restrictions relating to the Initial Securities and the provisions
relating to the matters described in Section 6 hereof) that would be registered under the
Securities Act. The Company shall use its best efforts to cause such Exchange Offer Registration
Statement to become effective under the Securities Act on or prior to November 7, 2005 and shall
keep the Exchange Offer Registration Statement effective for not less than 30 days (or longer, if
required by applicable law) after the date notice of the Registered Exchange Offer is mailed to the
Holders (such period being called the “Exchange Offer Registration Period”).

     If the Company effects the Registered Exchange Offer, the Company will be entitled to close
the Registered Exchange Offer 30 days after the commencement thereof provided that the Company has
accepted all the Initial Securities theretofore validly tendered in accordance with the terms of
the Registered Exchange Offer.

 

 

     Following the declaration of the effectiveness of the Exchange Offer Registration Statement,
the Company shall promptly commence the Registered Exchange Offer, it being the objective of such
Registered Exchange Offer to enable each Holder of Transfer Restricted Securities (as defined in
Section 6 hereof) electing to exchange the Initial Securities for Exchange Securities (assuming
that such Holder is not an affiliate of the Company within the meaning of the Securities Act,
acquires the Exchange Securities in the ordinary course of such Holder’s business and has no
arrangements with any person to participate in the distribution of the Exchange Securities and is
not prohibited by any law or policy of the Commission from participating in the Registered Exchange
Offer) to trade such Exchange Securities from and after their receipt without any limitations or
restrictions under the Securities Act and without material restrictions under the securities laws
of the several states of the United States.

     The Company acknowledges that, pursuant to current interpretations by the Commission’s staff
of Section 5 of the Securities Act, in the absence of an applicable exemption therefrom, (i) each
Holder which is a broker-dealer electing to exchange Securities, acquired for its own account as a
result of market making activities or other trading activities, for Exchange Securities (an
“Exchanging Dealer”), is required to deliver a prospectus containing the information set forth in
(a) Annex A hereto on the cover, (b) Annex B hereto in the “Exchange Offer Procedures” section and
the “Purpose of the Exchange Offer” section, and (c) Annex C hereto in the “Plan of Distribution”
section of such prospectus in connection with a sale of any such Exchange Securities received by
such Exchanging Dealer pursuant to the Registered Exchange Offer and (ii) an Initial Purchaser that
elects to sell Exchange Securities acquired in exchange for Securities constituting any portion of
an unsold allotment is required to deliver a prospectus containing the information required by
Items 507 or 508 of Regulation S-K under the Securities Act, as applicable, in connection with such
sale.

     The Company shall use its best efforts to keep the Exchange Offer Registration Statement
effective and to amend and supplement the prospectus contained therein, in order to permit such
prospectus to be lawfully delivered by all persons subject to the prospectus delivery requirements
of the Securities Act for such period of time as such persons must comply with such requirements in
order to resell the Exchange Securities; provided, however, that (i) in the case where such
prospectus and any amendment or supplement thereto must be delivered by an Exchanging Dealer or an
Initial Purchaser, such period shall be the lesser of 180 days and the date on which all Exchanging
Dealers and the Initial Purchaser have sold all Exchange Securities held by them (unless such
period is extended pursuant to Section 3(j) below) and (ii) the Company shall make such prospectus
and any amendment or supplement thereto, available to any broker-dealer for use in connection with
any resale of any Exchange Securities for a period of not less than 180 days after the consummation
of the Registered Exchange Offer.

     If, upon consummation of the Registered Exchange Offer, any Initial Purchaser holds Initial
Securities acquired by it as part of its initial distribution, the Company, simultaneously with the
delivery of the Exchange Securities pursuant to the Registered Exchange Offer, shall issue and
deliver to such Initial Purchaser upon the written request of such Initial Purchaser, in exchange
(the “Private Exchange”) for the Initial Securities held by such Initial Purchaser, a like
principal amount of debt securities of the Issuers issued under the Indenture and identical in all
material respects (including the existence of restrictions on transfer under the Securities Act and
the securities laws of the several states of the United States, but excluding provisions relating
to the matters described in Section 6 hereof) to the Initial Securities (the “Private Exchange
Securities”). The Initial Securities, the Exchange Securities and the Private Exchange Securities
are herein collectively called the “Securities”.

     In connection with the Registered Exchange Offer, the Company shall:

          (a) mail to each Holder a copy of the prospectus forming part of the Exchange Offer
Registration Statement, together with an appropriate letter of transmittal and related
documents;

          (b) keep the Registered Exchange Offer open for not less than 30 days (or longer, if
required by applicable law) after the date notice thereof is mailed to the Holders;

2

 

          (c) utilize the services of a depositary for the Registered Exchange Offer with an
address in the Borough of Manhattan, The City of New York, which may be the Trustee or an
affiliate of the Trustee;

          (d) permit Holders to withdraw tendered Securities at any time prior to the close of
business, New York time, on the last business day on which the Registered Exchange Offer
shall remain open; and

          (e) otherwise comply with all applicable laws.

     As soon as practicable after the close of the Registered Exchange Offer or the Private
Exchange, as the case may be, the Company shall:

          (x) accept for exchange all the Securities validly tendered and not withdrawn
pursuant to the Registered Exchange Offer and the Private Exchange;

          (y) deliver to the Trustee for cancellation all the Initial Securities so accepted
for exchange; and

          (z) cause the Trustee to authenticate and deliver promptly to each Holder of the
Initial Securities, Exchange Securities or Private Exchange Securities, as the case may be,
equal in principal amount to the Initial Securities of such Holder so accepted for
exchange.

     The Indenture will provide that the Exchange Securities will not be subject to the transfer
restrictions set forth in the Indenture and that all the Securities will vote and consent together
on all matters as one class and that none of the Securities will have the right to vote or consent
as a class separate from one another on any matter.

     Interest on each Exchange Security and Private Exchange Security issued pursuant to the
Registered Exchange Offer and in the Private Exchange will accrue from the last interest payment
date on which interest was paid on the Initial Securities surrendered in exchange therefor or, if
no interest has been paid on the Initial Securities, from the date of original issue of the Initial
Securities.

     Each Holder participating in the Registered Exchange Offer shall be required to represent to
the Company that at the time of the consummation of the Registered Exchange Offer (i) any Exchange
Securities received by such Holder will be acquired in the ordinary course of business, (ii) such
Holder will have no arrangements or understanding with any person to participate in the
distribution of the Securities or the Exchange Securities within the meaning of the Securities Act,
(iii) such Holder is not an “affiliate,” as defined in Rule 405 of the Securities Act, of the
Company or if it is an affiliate, such Holder will comply with the registration and prospectus
delivery requirements of the Securities Act to the extent applicable, (iv) if such Holder is not a
broker-dealer, that it is not engaged in, and does not intend to engage in, the distribution of the
Exchange Securities and (v) if such Holder is a broker-dealer, that it will receive Exchange
Securities for its own account in exchange for Initial Securities that were acquired as a result of
market-making activities or other trading activities and that it will be required to acknowledge
that it will deliver a prospectus in connection with any resale of such Exchange Securities.

     Notwithstanding any other provisions hereof, the Company will ensure that (i) any Exchange
Offer Registration Statement and any amendment thereto and any prospectus forming part thereof and
any supplement thereto complies in all material respects with the Securities Act and the rules and
regulations thereunder, (ii) any Exchange Offer Registration Statement and any amendment thereto
does not, when it becomes effective, 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 and (iii) any prospectus forming part of any Exchange Offer Registration Statement, and
any supplement to such prospectus, does not include an untrue statement of a material fact or omit
to state a material fact required to be stated therein

3

 

or necessary in order to make the statements therein, in the light of the circumstances under which
they were made, not misleading.

     2. Shelf Registration. If, (i) because of any change in law or in applicable interpretations
thereof by the staff of the Commission, the Company is not permitted to effect a Registered
Exchange Offer, as contemplated by Section 1 hereof, (ii) the Registered Exchange Offer is not
consummated on or prior to December 7, 2005, (iii) any Initial Purchaser so requests with respect
to the Initial Securities (or the Private Exchange Securities) not eligible to be exchanged for
Exchange Securities in the Registered Exchange Offer and held by it following consummation of the
Registered Exchange Offer or (iv) any Holder (other than an Exchanging Dealer) is not eligible to
participate in the Registered Exchange Offer or, in the case of any Holder (other than an
Exchanging Dealer) that participates in the Registered Exchange Offer, such Holder does not receive
freely tradeable Exchange Securities on the date of the exchange, the Company shall take the
following actions:

          (a) The Company shall, at its cost, file as promptly as practicable with the
Commission and thereafter shall use its best efforts to cause to be declared effective a
registration statement (the “Shelf Registration Statement” and, together with the Exchange
Offer Registration Statement, a “Registration Statement”) on an appropriate form under the
Securities Act relating to the offer and sale of the Transfer Restricted Securities (as
defined in Section 6 hereof) by the Holders thereof from time to time in accordance with
the methods of distribution set forth in the Shelf Registration Statement and Rule 415
under the Securities Act (hereinafter, the “Shelf Registration”) on or prior to December 7,
2005 in the case of clause (i) above and on or prior to the 60th day after the date on
which the Shelf Registration Statement is required to be filed in the case of clauses (ii),
(iii) and (iv) above; provided, however, that no Holder (other than an Initial Purchaser)
shall be entitled to have the Securities held by it covered by such Shelf Registration
Statement unless such Holder agrees in writing to be bound by all the provisions of this
Agreement applicable to such Holder.

          (b) The Company shall use its best efforts to keep the Shelf Registration Statement
continuously effective in order to permit the prospectus included therein to be lawfully
delivered by the Holders of the relevant Securities, for a period up to and including May
11, 2007 (or for such longer period if extended pursuant to Section 3(j) below) or such
shorter period that will terminate when all the Securities covered by the Shelf
Registration Statement (i) have been sold pursuant thereto or (ii) are no longer restricted
securities (as defined in Rule 144 under the Securities Act, or any successor rule
thereof). The Company shall be deemed not to have used its best efforts to keep the Shelf
Registration Statement effective during the requisite period if it voluntarily takes any
action that would result in Holders of Securities covered thereby not being able to offer
and sell such Securities during that period, unless such action is required by applicable
law.

          (c) Notwithstanding any other provisions of this Agreement to the contrary, the
Company shall cause the Shelf Registration Statement and the related prospectus and any
amendment or supplement thereto, as of the effective date of the Shelf Registration
Statement, amendment or supplement, (i) to comply in all material respects with the
applicable requirements of the Securities Act and the rules and regulations of the
Commission and (ii) not to contain any untrue statement of a material fact or omit to state
a material fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not misleading.

     3. Registration Procedures. In connection with any Shelf Registration contemplated by
Section 2 hereof and, to the extent applicable, any Registered Exchange Offer contemplated by
Section 1 hereof, the following provisions shall apply:

          (a) The Company shall (i) furnish to each Initial Purchaser, prior to the filing
thereof with the Commission, a copy of the Registration Statement and each amendment
thereof and each

4

 

supplement, if any, to the prospectus included therein and, in the event that an Initial
Purchaser (with respect to any portion of an unsold allotment from the original offering)
is participating in the Registered Exchange Offer or the Shelf Registration Statement, the
Company shall use its best efforts to reflect in each such document, when so filed with the
Commission, such comments as such Initial Purchaser reasonably may propose; (ii) include
the information set forth in Annex A hereto on the cover, in Annex B hereto in the
“Exchange Offer Procedures” section and the “Purpose of the Exchange Offer” section and in
Annex C hereto in the “Plan of Distribution” section of the prospectus forming a part of
the Exchange Offer Registration Statement and include the information set forth in Annex D
hereto in the Letter of Transmittal delivered pursuant to the Registered Exchange Offer;
(iii) if requested by an Initial Purchaser, include the information required by Items 507
or 508 of Regulation S-K under the Securities Act, as applicable, in the prospectus forming
a part of the Exchange Offer Registration Statement; (iv) include within the prospectus
contained in the Exchange Offer Registration Statement a section entitled “Plan of
Distribution,” reasonably acceptable to the Initial Purchaser, which shall contain a
summary statement of the positions taken or policies made by the staff of the Commission
with respect to the potential “underwriter” status of any broker-dealer that is the
beneficial owner (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as
amended (the “Exchange Act”)) of Exchange Securities received by such broker-dealer in the
Registered Exchange Offer (a “Participating Broker-Dealer”), whether such positions or
policies have been publicly disseminated by the staff of the Commission or such positions
or policies, in the reasonable judgment of the Initial Purchaser based upon advice of
counsel (which may be in-house counsel), represent the prevailing views of the staff of the
Commission; and (v) in the case of a Shelf Registration Statement, include the names of the
Holders, who propose to sell Securities pursuant to the Shelf Registration Statement, as
selling securityholders.

          (b) The Company shall give written notice to the Initial Purchaser, the Holders of
the Securities and any Participating Broker-Dealer from whom the Company has received prior
written notice that it will be a Participating Broker-Dealer in the Registered Exchange
Offer (which notice pursuant to clauses (ii)-(v) hereof shall be accompanied by an
instruction to suspend the use of the prospectus until the requisite changes have been
made):

               (i) when the Registration Statement or any amendment thereto has been filed
with the Commission and when the Registration Statement or any post-effective
amendment thereto has become effective;

               (ii) of any request by the Commission for amendments or supplements to the
Registration Statement or the prospectus included therein or for additional
information;

               (iii) of the issuance by the Commission of any stop order suspending the
effectiveness of the Registration Statement or the initiation of any proceedings
for that purpose;

               (iv) of the receipt by the Company or its legal counsel of any notification
with respect to the suspension of the qualification of the Securities for sale in
any jurisdiction or the initiation or threatening of any proceeding for such
purpose; and

               (v) of the happening of any event that requires the Company to make changes
in the Registration Statement or the prospectus in order that the Registration
Statement or the prospectus do not contain an untrue statement of a material fact
nor omit to state a material fact required to be stated therein or necessary to
make the statements therein (in the case of the prospectus, in light of the
circumstances under which they were made) not misleading.

          (c) The Company shall make every reasonable effort to obtain the withdrawal at the
earliest possible time, of any order suspending the effectiveness of the Registration
Statement.

5

 

          (d) The Company shall furnish to each Holder of Securities included within the
coverage of the Shelf Registration, without charge, at least one copy of the Shelf
Registration Statement and any post-effective amendment thereto, including financial
statements and schedules, and, if the Holder so requests in writing, all exhibits thereto
(including those, if any, incorporated by reference).

          (e) The Company shall deliver to each Exchanging Dealer and each Initial Purchaser,
and to any other Holder who so requests, without charge, at least one copy of the Exchange
Offer Registration Statement and any post-effective amendment thereto, including financial
statements and schedules, and, if any Initial Purchaser or any such Holder requests, all
exhibits thereto (including those incorporated by reference).

          (f) The Company shall, during the Shelf Registration Period, deliver to each Holder
of Securities included within the coverage of the Shelf Registration, without charge, as
many copies of the prospectus (including each preliminary prospectus) included in the Shelf
Registration Statement and any amendment or supplement thereto as such person may
reasonably request. The Company consents, subject to the provisions of this Agreement, to
the use of the prospectus or any amendment or supplement thereto by each of the selling
Holders of the Securities in connection with the offering and sale of the Securities
covered by the prospectus, or any amendment or supplement thereto, included in the Shelf
Registration Statement.

          (g) The Company shall deliver to each Initial Purchaser, any Exchanging Dealer, any
Participating Broker-Dealer and such other persons required to deliver a prospectus
following the Registered Exchange Offer, without charge, as many copies of the final
prospectus included in the Exchange Offer Registration Statement and any amendment or
supplement thereto as such persons may reasonably request. The Company consents, subject
to the provisions of this Agreement, to the use of the prospectus or any amendment or
supplement thereto by any Initial Purchaser, if necessary, any Participating Broker-Dealer
and such other persons required to deliver a prospectus following the Registered Exchange
Offer in connection with the offering and sale of the Exchange Securities covered by the
prospectus, or any amendment or supplement thereto, included in such Exchange Offer
Registration Statement.

          (h) Prior to any public offering of the Securities, pursuant to any Registration
Statement, the Company shall register or qualify or cooperate with the Holders of the
Securities included therein and their respective counsel in connection with the
registration or qualification of the Securities for offer and sale under the securities or
“blue sky” laws of such states of the United States as any Holder of the Securities
reasonably requests in writing and do any and all other acts or things necessary or
advisable to enable the offer and sale in such jurisdictions of the Securities covered by
such Registration Statement; provided, however, that the Company shall 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 which would subject it to general service of process or to taxation
in any jurisdiction where it is not then so subject.

          (i) The Company shall cooperate with the Holders of the Securities to facilitate the
timely preparation and delivery of certificates representing the Securities to be sold
pursuant to any Registration Statement free of any restrictive legends and in such
denominations and registered in such names as the Holders may request a reasonable period
of time prior to sales of the Securities pursuant to such Registration Statement.

          (j) Upon the occurrence of any event contemplated by paragraphs (ii) through (v) of
Section 3(b) above during the period for which the Company is required to maintain an
effective Registration Statement, the Company shall promptly prepare and file a
post-effective amendment to the Registration Statement or a supplement to the related
prospectus and any other required document so that, as thereafter delivered to Holders of
the Securities or purchasers of Securities,

6

 

the prospectus will not contain an untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading. If the Company
notifies the Initial Purchaser, the Holders of the Securities and any known Participating
Broker-Dealer in accordance with paragraphs (ii) through (v) of Section 3(b) above to
suspend the use of the prospectus until the requisite changes to the prospectus have been
made, then the Initial Purchaser, the Holders of the Securities and any such Participating
Broker-Dealers shall suspend use of such prospectus, and the period of effectiveness of the
Shelf Registration Statement provided for in Section 2(b) above and the Exchange Offer
Registration Statement provided for in Section 1 above shall each be extended by the number
of days from and including the date of the giving of such notice to and including the date
when the Initial Purchaser, the Holders of the Securities and any known Participating
Broker-Dealer shall have received such amended or supplemented prospectus pursuant to this
Section 3(j).

          (k) Not later than the effective date of the applicable Registration Statement, the
Company will provide a CUSIP number for the Initial Securities, the Exchange Securities or
the Private Exchange Securities, as the case may be, and provide the applicable trustee
with printed certificates for the Initial Securities, the Exchange Securities or the
Private Exchange Securities, as the case may be, in a form eligible for deposit with The
Depository Trust Company.

          (l) The Company will comply with all rules and regulations of the Commission to the
extent and so long as they are applicable to the Registered Exchange Offer or the Shelf
Registration and will make generally available to its security holders (or otherwise
provide in accordance with Section 11(a) of the Securities Act) an earnings statement
satisfying the provisions of Section 11(a) of the Securities Act, no later than 45 days
after the end of a 12-month period (or 90 days, if such period is a fiscal year) beginning
with the first month of the Company’s first fiscal quarter commencing after the effective
date of the Registration Statement, which statement shall cover such 12-month period.

          (m) The Company shall cause the Indenture to be qualified under the Trust Indenture
Act of 1939, as amended, in a timely manner and containing such changes, if any, as shall
be necessary for such qualification. In the event that such qualification would require
the appointment of a new trustee under the Indenture, the Company shall appoint a new
trustee thereunder pursuant to the applicable provisions of the Indenture.

          (n) The Company may require each Holder of Securities to be sold pursuant to the
Shelf Registration Statement to furnish to the Company such information regarding the
Holder and the distribution of the Securities as the Company may from time to time
reasonably require for inclusion in the Shelf Registration Statement, and the Company may
exclude from such registration the Securities of any Holder that unreasonably fails to
furnish such information within a reasonable time after receiving such request.

          (o) The Company shall enter into such customary agreements (including, if requested,
an underwriting agreement in customary form) and take all such other action, if any, as any
Holder of the Securities shall reasonably request in order to facilitate the disposition of
the Securities pursuant to any Shelf Registration.

          (p) In the case of any Shelf Registration, the Company shall (i) make reasonably
available for inspection by the Holders of the Securities, any underwriter participating in
any disposition pursuant to the Shelf Registration Statement and any attorney, accountant
or other agent retained by the Holders of the Securities or any such underwriter all
relevant financial and other records, pertinent corporate documents and properties of the
Company and (ii) cause the Company’s officers, directors, employees, accountants and
auditors to supply all relevant information reasonably requested by the Holders of the
Securities or any such underwriter, attorney, accountant or agent in connection with the
Shelf Registration Statement, in each case, as

7

 

shall be reasonably necessary to enable such persons, to conduct a reasonable investigation
within the meaning of Section 11 of the Securities Act; provided, however, that the
foregoing inspection and information gathering shall be coordinated on behalf of the
Initial Purchaser by you and on behalf of the other parties, by one counsel designated by
and on behalf of such other parties as described in Section 4 hereof.

          (q) In the case of any Shelf Registration, the Company, if requested by any Holder of
Securities covered thereby, shall cause (i) its counsel to deliver an opinion and updates
thereof relating to the Securities in customary form addressed to such Holders and the
managing underwriters, if any, thereof and dated, in the case of the initial opinion, the
effective date of such Shelf Registration Statement (it being agreed that the matters to be
covered by such opinion shall include, without limitation, the due incorporation and good
standing of the Company and its subsidiaries; the qualification of the Company and its
subsidiaries to transact business as foreign corporations; the due authorization, execution
and delivery of the relevant agreement of the type referred to in Section 3(o) hereof; the
due authorization, execution, authentication and issuance, and the validity and
enforceability, of the applicable Securities; the absence of material legal or governmental
proceedings involving the Company and its subsidiaries; the absence of governmental
approvals required to be obtained in connection with the Shelf Registration Statement, the
offering and sale of the applicable Securities, or any agreement of the type referred to in
Section 3(o) hereof; the compliance as to form of such Shelf Registration Statement and any
documents incorporated by reference therein and of the Indenture with the requirements of
the Securities Act and the Trust Indenture Act, respectively; and, as of the date of the
opinion and as of the effective date of the Shelf Registration Statement or most recent
post-effective amendment thereto, as the case may be, the absence from such Shelf
Registration Statement and the prospectus included therein, as then amended or
supplemented, and from any documents incorporated by reference therein of an untrue
statement of a material fact or the omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading (in the case
of any such documents, in the light of the circumstances existing at the time that such
documents were filed with the Commission under the Exchange Act); (ii) its officers to
execute and deliver all customary documents and certificates and updates thereof requested
by any underwriters of the applicable Securities and (iii) its independent public
accountants to provide to the selling Holders of the applicable Securities and any
underwriter therefor a comfort letter in customary form and covering matters of the type
customarily covered in comfort letters in connection with primary underwritten offerings,
subject to receipt of appropriate documentation as contemplated, and only if permitted, by
Statement of Auditing Standards No. 72.

          (r) In the case of the Registered Exchange Offer, if requested by any Initial
Purchaser or any known Participating Broker-Dealer, the Company shall cause (i) its counsel
to deliver to such Initial Purchaser or such Participating Broker-Dealer a signed opinion
in the form set forth in Section 6(c) of the Purchase Agreement with such changes as are
customary in connection with the preparation of a Registration Statement and (ii) its
independent public accountants to deliver to such Initial Purchaser or such Participating
Broker-Dealer a comfort letter, in customary form, meeting the requirements as to the
substance thereof as set forth in Section 6(a) of the Purchase Agreement, with appropriate
date changes.

          (s) If a Registered Exchange Offer or a Private Exchange is to be consummated, upon
delivery of the Initial Securities by Holders to the Company (or to such other Person as
directed by the Company) in exchange for the Exchange Securities or the Private Exchange
Securities, as the case may be, the Company shall mark, or cause to be marked, on the
Initial Securities so exchanged that such Initial Securities are being canceled in exchange
for the Exchange Securities or the Private Exchange Securities, as the case may be; in no
event shall the Initial Securities be marked as paid or otherwise satisfied.

          (t) The Company will use its best efforts to (a) if the Initial Securities have been
rated prior to the initial sale of such Initial Securities, confirm such ratings will apply
to the Securities

8

 

covered by a Registration Statement, or (b) if the Initial Securities were not previously
rated, cause the Securities covered by a Registration Statement to be rated with the
appropriate rating agencies, if so requested by Holders of a majority in aggregate
principal amount of Securities covered by such Registration Statement, or by the managing
underwriters, if any.

          (u) In the event that any broker-dealer registered under the Exchange Act shall
underwrite any Securities or participate as a member of an underwriting syndicate or
selling group or “assist in the distribution” (within the meaning of the Conduct Rules (the
“Rules”) of the National Association of Securities Dealers, Inc. (“NASD”)) thereof, whether
as a Holder of such Securities or as an underwriter, a placement or sales agent or a broker
or dealer in respect thereof, or otherwise, the Company will assist such broker-dealer in
complying with the requirements of such Rules, including, without limitation, by (i) if
such Rules, including Rule 2720, shall so require, engaging a “qualified independent
underwriter” (as defined in Rule 2720) to participate in the preparation of the
Registration Statement relating to such Securities, to exercise usual standards of due
diligence in respect thereto and, if any portion of the offering contemplated by such
Registration Statement is an underwritten offering or is made through a placement or sales
agent, to recommend the yield of such Securities, (ii) indemnifying any such qualified
independent underwriter to the extent of the indemnification of underwriters provided in
Section 5 hereof and (iii) providing such information to such broker-dealer as may be
required in order for such broker-dealer to comply with the requirements of the Rules.

          (v) The Company shall use its best efforts to take all other steps necessary to
effect the registration of the Securities covered by a Registration Statement contemplated
hereby.

     4. Registration Expenses. The Company shall bear all fees and
expenses incurred in connection with the performance of its obligations under Sections 1 through 3
hereof whether or not the Exchange Offer Registration Statement or Shelf Registration Statement is
declared effective. The Company shall also shall bear or reimburse the Initial Purchaser and the
Holders of the Securities covered thereby for the reasonable fees and disbursements of one firm of
counsel designated by the Holders of a majority in principal amount of the Initial Securities
covered thereby to act as counsel for the Initial Purchaser and the Holders of the Initial
Securities in connection therewith.

     5. Indemnification. (a) The Company agrees to indemnify and hold harmless each Holder of
the Securities, any Participating Broker-Dealer and each person, if any, who controls such Holder
or such Participating Broker-Dealer within the meaning of the Securities Act or the Exchange Act
(each Holder, any Participating Broker-Dealer and such controlling persons are referred to
collectively as the “Indemnified Parties”) from and against any losses, claims, damages or
liabilities, joint or several, or any actions in respect thereof (including, but not limited to,
any losses, claims, damages, liabilities or actions relating to purchases and sales of the
Securities) to which each Indemnified Party may become subject under the Securities Act, the
Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise
out of or are based upon any untrue statement or alleged untrue statement of a material fact
contained in a Registration Statement or prospectus or in any amendment or supplement thereto or in
any preliminary prospectus relating to a Shelf Registration, 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 not misleading, and shall reimburse, as incurred, the
Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action in respect thereof;
provided, however, that (i) the Company shall not be liable in any such case to the extent that
such loss, claim, damage or liability arises out of or is based upon any untrue statement or
alleged untrue statement or omission or alleged omission made in a Registration Statement or
prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to a
Shelf Registration in reliance upon and in conformity with written information pertaining to such
Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion
therein and (ii) with respect to any untrue statement or omission or alleged untrue statement or
omission made in any preliminary prospectus relating to a Shelf Registration Statement, the
indemnity agreement contained in this subsection (a) shall not inure to the benefit of any Holder
or Participating Broker-Dealer from whom

9

 

the person asserting any such losses, claims, damages or liabilities purchased the Securities
concerned, to the extent that a prospectus relating to such Securities was required to be delivered
by such Holder or Participating Broker-Dealer under the Securities Act in connection with such
purchase and any such loss, claim, damage or liability of such Holder or Participating
Broker-Dealer results from the fact that there was not sent or given to such person, at or prior to
the written confirmation of the sale of such Securities to such person, a copy of the final
prospectus if the Company had previously furnished copies thereof to such Holder or Participating
Broker-Dealer; provided further, however, that this indemnity agreement will be in addition to any
liability which the Company may otherwise have to such Indemnified Party. The Company shall also
indemnify underwriters, their officers and directors and each person who controls such underwriters
within the meaning of the Securities Act or the Exchange Act to the same extent as provided above
with respect to the indemnification of the Holders of the Securities if requested by such Holders.

     (b) Each Holder of the Securities, severally and not jointly, will indemnify and hold
harmless the Company and each person, if any, who controls the Company within the meaning of the
Securities Act or the Exchange Act from and against any losses, claims, damages or liabilities or
any actions in respect thereof, to which the Company or any such controlling person may become
subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims,
damages, liabilities or actions arise out of or are based upon any untrue statement or alleged
untrue statement of a material fact contained in a Registration Statement or prospectus or in any
amendment or supplement thereto or in any preliminary prospectus relating to a Shelf Registration,
or arise out of or are based upon the omission or alleged omission to state therein a material fact
necessary to make the statements therein not misleading, but in each case only to the extent that
the untrue statement or omission or alleged untrue statement or omission was made in reliance upon
and in conformity with written information pertaining to such Holder and furnished to the Company
by or on behalf of such Holder specifically for inclusion therein; and, subject to the limitation
set forth immediately preceding this clause, shall reimburse, as incurred, the Company for any
legal or other expenses reasonably incurred by the Company or any such controlling person in
connection with investigating or defending any loss, claim, damage, liability or action in respect
thereof. This indemnity agreement will be in addition to any liability which such Holder may
otherwise have to the Company or any of its controlling persons.

     (c) Promptly after receipt by an indemnified party under this Section 5 of notice of the
commencement of any action or proceeding (including a governmental investigation), such indemnified
party will, if a claim in respect thereof is to be made against the indemnifying party under this
Section 5, notify the indemnifying party of the commencement thereof; but the failure to notify the
indemnifying party shall not relieve the indemnifying party from any liability that it may have
under subsection (a) or (b) above except to the extent that it has been materially prejudiced
(through the forfeiture of substantive rights or defenses) by such failure; and provided further
that the failure to notify the indemnifying party shall not relieve it from any liability that it
may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any
such action is brought against any indemnified party, and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate therein and, to the
extent that it may wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not,
except with the consent of the indemnified party, be counsel to the indemnifying party), and after
notice from the indemnifying party to such indemnified party of its election so to assume the
defense thereof the indemnifying party will not be liable to such indemnified party under this
Section 5 for any legal or other expenses, other than reasonable costs of investigation,
subsequently incurred by such indemnified party in connection with the defense thereof. No
indemnifying party shall, without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened action in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such indemnified party
unless such settlement (i) includes an unconditional release of such indemnified party from all
liability on any claims that are the subject matter of such action, and (ii) does not include a
statement as to or an admission of fault, culpability or a failure to act by or on behalf of any
indemnified party.

10

 

     (d) If the indemnification provided for in this Section 5 is unavailable or insufficient to
hold harmless an indemnified party under subsections (a) or (b) above, then each indemnifying party
shall contribute to the amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to in subsection (a) or (b)
above (i) in such proportion as is appropriate to reflect the relative benefits received by the
indemnifying party or parties on the one hand and the indemnified party on the other from the
exchange of the Securities, pursuant to the Registered Exchange Offer, or (ii) if the allocation
provided by the foregoing clause (i) is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i) above but also the
relative fault of the indemnifying party or parties on the one hand and the indemnified party on
the other in connection with the statements or omissions that resulted in such losses, claims,
damages or liabilities (or actions in respect thereof) as well as any other relevant equitable
considerations. The relative fault of the parties 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 relates to information supplied by the Company on the one
hand or such Holder or such other indemnified party, as the case may be, on the other, and the
parties’ relative intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The amount paid by an indemnified party as a result of the losses,
claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be
deemed to include any legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any action or claim which is the subject of this
subsection (d). Notwithstanding any other provision of this Section 5(d), the Holders of the
Securities shall not be required to contribute any amount in excess of the amount by which the net
proceeds received by such Holders from the sale of the Securities pursuant to a Registration
Statement exceeds the amount of damages which such Holders have otherwise been required to pay 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. For purposes of this paragraph (d), each person, if any, who controls such
indemnified party within the meaning of the Securities Act or the Exchange Act shall have the same
rights to contribution as such indemnified party and each person, if any, who controls the Company
within the meaning of the Securities Act or the Exchange Act shall have the same rights to
contribution as the Company.

     (e) The agreements contained in this Section 5 shall survive the sale of the Securities
pursuant to a Registration Statement and shall remain in full force and effect, regardless of any
termination or cancellation of this Agreement or any investigation made by or on behalf of any
indemnified party.

     6. Additional Interest Under Certain Circumstances. (a) Additional interest (the
“Additional Interest”) with respect to the Initial Securities shall be assessed as follows if any
of the following events occur (each such event in clauses (i) through (vii) below a “Registration
Default”):

          (i) If by August 9, 2005, the Company has not filed the Exchange Offer Registration
Statement;

          (ii) If by November 7, 2005, the Exchange Offer Registration Statement has not been
declared effective by the Commission;

          (iii) If the Company is obligated to file a Shelf Registration Statement and such
Shelf Registration Statement has not been declared effective by December 7, 2005;

          (iv) If the Exchange Offer is not consummated on or before the 30th day
after the Exchange Registration Statement has been declared effective by the Commission;

          (v) If the Company is obligated to file a Shelf Registration Statement and such Shelf
Registration Statement has not been filed on or prior to the 30th day (the
“Shelf Filing Date”) after the date such obligation to file the Shelf Registration
Statement arises;

11

 

          (vi) If the Company is obligated to file a Shelf Registration Statement and such Shelf
Registration Statement has not been declared effective on or prior to the 60th
day after the Shelf Filing Date; or

          (vii) If after either the Exchange Offer Registration Statement or the Shelf
Registration Statement is declared effective (A) such Registration Statement thereafter
ceases to be effective; or (B) such Registration Statement or the related prospectus ceases
to be usable (except as permitted in paragraph (b)) in connection with resales of Transfer
Restricted Securities during the periods specified herein because either (1) any event
occurs as a result of which the related prospectus forming part of such Registration
Statement would include any untrue statement of a material fact or omit to state any
material fact necessary to make the statements therein in the light of the circumstances
under which they were made not misleading, or (2) it shall be necessary to amend such
Registration Statement or supplement the related prospectus, to comply with the Securities
Act or the Exchange Act or the respective rules thereunder.

Additional Interest shall accrue on the Initial Securities over and above the interest set forth in
the title of the Securities from and including the date on which any such Registration Default
shall occur to but excluding the date on which all such Registration Defaults have been cured, at a
rate of 0.50% per annum for the first 90-day period immediately following the occurrence of such
Registration Default. The Additional Interest Rate shall increase by an additional 0.50% per annum
with respect to each subsequent 90-day period until all Registration Defaults have been cured, up
to a maximum Additional Interest Rate of 1.5% per annum.

     (b) A Registration Default referred to in Section 6(a)(vii)(B) hereof shall be deemed not to
have occurred and be continuing in relation to a Shelf Registration Statement or the related
prospectus if (i) such Registration Default has occurred solely as a result of (x) the filing of a
post-effective amendment to such Shelf Registration Statement to incorporate annual audited
financial information with respect to the Company where such post-effective amendment is not yet
effective and needs to be declared effective to permit Holders to use the related prospectus or (y)
other material events, with respect to the Company that would need to be described in such Shelf
Registration Statement or the related prospectus and (ii) in the case of clause (y), the Company is
proceeding promptly and in good faith to amend or supplement such Shelf Registration Statement and
related prospectus to describe such events; provided, however, that in any case if such
Registration Default occurs for a continuous period in excess of 30 days, Additional Interest shall
be payable in accordance with the above paragraph from the day such Registration Default occurs
until such Registration Default is cured.

     (c) Any amounts of Additional Interest due pursuant to clauses (i)-(vii) of Section 6(a)
above will be payable in cash on the regular interest payment dates with respect to the Initial
Securities. The amount of Additional Interest will be determined by multiplying the applicable
Additional Interest rate by the principal amount of the Initial Securities, multiplied by a
fraction, the numerator of which is the number of days such Additional Interest rate was applicable
during such period (determined on the basis of a 360-day year comprised of twelve 30-day months),
and the denominator of which is 360.

     (d) “Transfer Restricted Securities” means each Security until (i) the date on which such
Transfer Restricted Security has been exchanged by a person other than a broker-dealer for a freely
transferable Exchange Security in the Registered Exchange Offer, (ii) following the exchange by a
broker-dealer in the Registered Exchange Offer of an Initial Security for an Exchange Note, the
date on which such Exchange Note is sold to a purchaser who receives from such broker-dealer on or
prior to the date of such sale a copy of the prospectus contained in the Exchange Offer
Registration Statement, (iii) the date on which such Initial Security has been effectively
registered under the Securities Act and disposed of in accordance with the Shelf Registration
Statement or (iv) the date on which such Initial Securities is distributed to the public pursuant
to Rule 144 under the Securities Act or is saleable pursuant to Rule 144(k) under the Securities
Act.

12

 

     7. Rules 144 and 144A. The Company shall use its best efforts to file the reports required
to be filed by it under the Securities Act and the Exchange Act in a timely manner and, if at any
time the Company is not required to file such reports, it will, upon the request of any Holder of
Initial Securities, make publicly available other information so long as necessary to permit sales
of their securities pursuant to Rules 144 and 144A. The Company covenants that it will take such
further action as any Holder of Initial Securities may reasonably request, all to the extent
required from time to time to enable such Holder to sell Initial Securities without registration
under the Securities Act within the limitation of the exemptions provided by Rules 144 and 144A
(including the requirements of Rule 144A(d)(4)). The Company will provide a copy of this Agreement
to prospective purchasers of Initial Securities identified to the Company by the Initial Purchaser
upon request. Upon the request of any Holder of Initial Securities, the Company shall deliver to
such Holder a written statement as to whether it has complied with such requirements.
Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the Company to
register any of its securities pursuant to the Exchange Act.

     8. Underwritten Registrations. If any of the Transfer Restricted Securities covered by any
Shelf Registration are to be sold in an underwritten offering, the investment banker or investment
bankers and manager or managers that will administer the offering (“Managing Underwriters”) will be
selected by the Holders of a majority in aggregate principal amount of such Transfer Restricted
Securities to be included in such offering.

     No person may participate in any underwritten registration hereunder unless such person (i)
agrees to sell such person’s Transfer Restricted Securities on the basis reasonably provided in any
underwriting arrangements approved by the persons entitled hereunder to approve such arrangements
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.

     9. Miscellaneous.

     (a) Amendments and Waivers. The provisions of this Agreement may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof may not be given,
except by the Company and the written consent of the Holders of a majority in principal amount of
the Securities affected by such amendment, modification, supplement, waiver or consents.

     (b) Notices. All notices and other communications provided for or permitted hereunder shall

ANNEX A

     Each broker-dealer that receives Exchange Securities for its own account pursuant to the
Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of
such Exchange Securities. The Letter of Transmittal states that by so acknowledging and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter”
within the meaning of the Securities Act. This Prospectus, as it may be amended or supplemented
from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities
received in exchange for Initial Securities where such Initial Securities were acquired by such
broker-dealer as a result of market-making activities or other trading activities. The Company has
agreed that, for a period of 180 days after the Expiration Date (as defined herein), it will make
this Prospectus available to any broker-dealer for use in connection with any such resale. See
“Plan of Distribution.”

 

 

ANNEX B

     Each broker-dealer that receives Exchange Securities for its own account in exchange for
Securities, where such Initial Securities were acquired by such broker-dealer as a result of
market-making activities or other trading activities, must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Securities. See “Plan of Distribution.”

 

 

ANNEX C

PLAN OF DISTRIBUTION

     Each broker-dealer that receives Exchange Securities for its own account pursuant to the
Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of
such Exchange Securities. This Prospectus, as it may be amended or supplemented from time to time,
may be used by a broker-dealer in connection with resales of Exchange Securities received in
exchange for Initial Securities where such Initial Securities were acquired as a result of
market-making activities or other trading activities. The Company has agreed that, for a period of
180 days after the Expiration Date, it will make this prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with any such
resale. In addition   , until, 20 , all dealers effecting transactions in the Exchange Securities may be required to deliver
a prospectus.1

     The Company will not receive any proceeds from any sale of Exchange Securities by
broker-dealers. Exchange Securities received by broker-dealers for their own account pursuant to
the Exchange Offer may be sold from time to time in one or more transactions in the
over-the-counter market, in negotiated transactions, through the writing of options on the Exchange
Securities or a combination of such methods of resale, at market prices prevailing at the time of
resale, at prices related to such prevailing market prices or negotiated prices. Any such resale
may be made directly to purchasers or to or through brokers or dealers who may receive compensation
in the form of commissions or concessions from any such broker-dealer or the purchasers of any such
Exchange Securities. Any broker-dealer that resells Exchange Securities that were received by it
for its own account pursuant to the Exchange Offer and any broker or dealer that participates in a
distribution of such Exchange Securities may be deemed to be an “underwriter” within the meaning of
the Securities Act and any profit on any such resale of Exchange Securities and any commission or
concessions received by any such persons may be deemed to be underwriting compensation under the
Securities Act. The Letter of Transmittal states that, by acknowledging that it will deliver and
by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter”
within the meaning of the Securities Act.

     For a period of 180 days after the Expiration Date the Company will promptly send additional
copies of this Prospectus and any amendment or supplement to this Prospectus to any broker-dealer
that requests such documents in the Letter of Transmittal. The Company has agreed to pay all
expenses incident to the Exchange Offer (including the expenses of one counsel for the Holders of
the Securities) other than commissions or concessions of any brokers or dealers and will indemnify
the Holders of the Securities (including any broker-dealers) against certain liabilities, including
liabilities under the Securities Act.

502(e) of Regulation S-K will appear on the back cover page of the Exchange
Offer.

If the undersigned is not a broker-dealer, the undersigned represents that it is not engaged in,
and does not intend to engage in, a distribution of Exchange Securities. If the undersigned is a
broker-dealer that will receive Exchange Securities for its own account in exchange for Initial
Securities that were acquired as a result of market-making activities or other trading activities,
it acknowledges that it will deliver a prospectus in connection with any resale of such Exchange
Securities; however, by so acknowledging and by delivering a prospectus, the undersigned will not
be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.exv10w1

 

EXHIBIT 10.1

EIGHTH AMENDMENT TO

AMENDED AND RESTATED CREDIT AGREEMENT

THIS EIGHTH AMENDMENT TO AMENDED AND RESTATED CREDIT AGREEMENT (the “Amendment”) dated June
17, 2005, by and among PETROQUEST ENERGY, L.L.C., a Louisiana limited liability company
(“Borrower”); PETROQUEST ENERGY, INC., a Delaware corporation (“PEI” ); PITTRANS,
INC., an Oklahoma corporation (“Pittrans,”); TDC ENERGY, LLC (f/k/a TDC ACQUISITION SUB
LLC), a Louisiana limited liability company (“TDC Energy,” who along with PEI and Pittrans
are, or will become, a “Guarantor”); JPMORGAN CHASE BANK, N.A. (successor by merger to BANK
ONE, N.A. (Main Office Chicago)) (individually as a lender and as agent, “Agent”) and the
financial institutions set forth on the signature pages hereto, (“Lenders”).

R E C I T A L S:

     WHEREAS, Borrower, PEI, Agent and Union Bank of California entered into an Amended and
Restated Credit Agreement dated May 14, 2003 (which as the same may have been and be amended from

and perform this Amendment and all other instruments referred to or mentioned herein to
which it is a party, and all action on its part requisite for the due execution, delivery

which Borrower or Guarantors are subject, and does not require the consent or approval of

     (b) After giving affect to this Amendment, the representations and warranties contained

generality of the foregoing, the Security Instruments and all collateral described therein
do and shall continue to secure the payment of all obligations of Borrower and Guarantors
under the Credit Agreement and the Note(s), as amended hereby, and under the other Security
Instruments.

     (c) The execution, delivery and effectiveness of this Amendment shall not, except as
expressly provided herein, operate as a waiver of any right, power or remedy of Lender under
any of the Security Instruments, nor constitute a waiver of any provision of any of the
Security Instruments.

     6. Delivery of Closing Documents. Borrower shall deliver to the Agent and the Lenders
copies of all documentation executed at the closing of the offering and sale of Senior Notes
pursuant to the Confidential Offering Circular dated June 3, 2005, certified by an Authorized
Officer of Borrower to the effect that such documents are true, correct and complete, within five
(5) Business Days after such closing.

     7. Waiver. As additional consideration for the execution, delivery and performance of
this Amendment by the parties hereto and to induce Lenders to enter into this Amendment, Borrower
and Guarantors each warrants and represents to Lenders that no facts, events, statuses or
conditions exist or have existed which, either now or with the passage of time or giving of notice,
or both, constitute or will constitute a basis for any claim or cause of action against Lenders or
any defense to (i) the payment of any obligations and indebtedness under the Note(s) and/or the
Security Instruments, or (ii) the performance of any of its obligations with respect to the Note(s)
and/or the Security Instruments, and in the event any such facts, events, statuses or conditions
exist or have existed, Borrower unconditionally and irrevocably waives any and all claims and
causes of action against Lenders and any defenses to its payment and performance obligations in
respect to the Note(s) and the Security Instruments.

     8. Costs and Expenses. Borrower agrees to pay on demand all costs and expenses of
Lenders in connection with the preparation, reproduction, execution and delivery of this Amendment

and out-of-pocket expenses of counsel for Lenders. In addition, Borrower shall pay any and all
fees payable or determined to be payable in connection with the execution and delivery, filing or
recording of this Amendment and the other instruments and documents to be delivered hereunder,

 

 

and agrees to save Lenders harmless from and against any and all liabilities with respect to or resulting
from any delay in paying or omitting to pay such fees.

     9. Execution in Counterparts. This Amendment may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of which when so
executed and delivered shall be deemed to be an original and all of which taken together shall
constitute but one and the same instrument.

     10. Governing Law. This Amendment shall be governed by and construed in accordance
with the laws of the State of Texas.

     11. Final Agreement. THIS WRITTEN AMENDMENT REPRESENTS THE FINAL AGREEMENT BETWEEN
