between

and

Public Service Company of Colorado

Dated: October 1, 2001

 

 

Contract No. 31050000

No-Notice Storage and Transportation Delivery Service Agreement

Rate Schedule NNT-1

	   	The Parties identified below, in consideration of their mutual promises, agree as follows:
	 
	1.  	Transporter: COLORADO INTERSTATE GAS COMPANY
	 
	2.  	Shipper: PUBLIC SERVICE COMPANY OF COLORADO
	 
	3.  	Applicable Tariff: Transporter’s FERC Gas Tariff, First Revised Volume No. 1, as the same
may be amended or superseded from time to time (“the Tariff”).
	 
	4.  	Changes in Rates and Terms: Transporter shall have the right to propose to the FERC changes
in its rates and terms of service, and this Agreement shall be deemed to include any changes
which are made effective pursuant to FERC Order or regulation or provisions of law, without
prejudice to Shipper’s right to protest the same.
	 
	5.  	Transportation Service: Transportation Service at and between Point of Withdrawal and
Primary Point(s) of Delivery shall be on a firm basis. Delivery of quantities at Secondary
Point(s) shall be in accordance with the Tariff.
	 
	6.  	Delivery: Transporter agrees to transport and deliver Delivery Quantities to Shipper (or
for Shipper’s account) at the Point(s) of Delivery identified in the attached Exhibit “A.”
Minimum and Maximum delivery pressures, as applicable, are listed on Exhibit “A.”
	 
	7.  	Rates and Surcharges: As set forth in Exhibit “B.” For example, Transporter and Shipper may
agree that a specified discount rate will apply: (a) only to certain specified firm service
entitlements under this Agreement; (b) only if specified quantity levels are actually
achieved under this Agreement (with higher rates, charges, and fees applicable to all
quantities above those levels, or to all quantities under the Agreement if the specified
levels are not achieved); (c) only to production reserves committed by the Shipper; (d) only
during specified time periods; (e) only to specified Point(s) of Receipt, Point(s) of
Delivery, mainline area segments, supply areas, Transportation routes, or defined geographical
areas under the associated Transportation Agreement; or (f) in a specified relationship to
the quantities actually Delivered (i.e., that the rates shall be adjusted in a specified
relationship to quantities actually Delivered); provided, however, that any such discounted
rates set forth above shall be between the minimum and maximum rates applicable to the service
provided under this Agreement.
	 
	   	In addition, the discount agreement may include a provision that if one rate component
which was at or below the applicable maximum rate at the time the discount agreement was
executed subsequently exceeds the applicable maximum rate due to a change in Transporter’s
maximum rates so that such rate component must be adjusted downward to equal the new applicable
maximum rate, then other rate components may be adjusted upward to achieve the agreed overall
rate, so long as none of the resulting rate components exceed the maximum rate applicable to
that rate component. Such changes to rate components shall be applied prospectively, commencing
with the date a Commission order accepts revised tariff sheets. However, nothing contained
herein shall be construed to alter a refund obligation under applicable law for any period
during which rates that had been charged under a discount agreement exceeded rates which
ultimately are found to be just and reasonable.
	 
	8.  	For the period October 1, 2001 through Aprf 30, 2007:

	 	 	 
	Maximum Delivery Quantity (“MDQ”):

	 	637,144 Dth per Day
	Maximum Available Capacity (“MAC”):

	Maximum Daily Injection Quantity (“MDIQ”):

     INDENTURE dated as of May 11, 2005, among PETROQUEST ENERGY, INC., a
Delaware corporation (the “Company”), PETROQUEST ENERGY, L.L.C., a
Louisiana limited liability company (“PELLC” and, together with the
Company, the “Issuers”), the SUBSIDIARY GUARANTORS identified herein and
THE BANK OF NEW YORK TRUST COMPANY, N.A., a national banking association
(the “Trustee”).

          Each party agrees as follows for the benefit of the other parties and for the equal and
ratable benefit of the Holders of the Issuers’ Initial Securities, Exchange Securities, Private
Exchange Securities and other securities issued under this Indenture (collectively, the
“Securities”).

ARTICLE 1

Definitions and Incorporation by Reference

          SECTION 1.01. Definitions.

          “Additional Assets” means:

     (1) any property, plant or equipment used in a Related Business;

     (2) the Capital Stock of a Person that becomes a Restricted Subsidiary as a result of
the acquisition of such Capital Stock by the Company or another Restricted Subsidiary; or

     (3) Capital Stock constituting a minority interest in any Person that at such time is
a Restricted Subsidiary;

provided, however, that any such Restricted Subsidiary described in clause (2) or
(3) above is primarily engaged in a Related Business.

          “Additional Securities” means Securities issued under this Indenture after the Issue Date and
in compliance with Section 2.13 and 4.03, it being understood that any Securities issued in
exchange for or replacement of any Initial Security issued on the Issue Date shall not be an
Additional Security, including any such Securities issued pursuant to a Registration Rights
Agreement.

          “Adjusted ACNTA” means, as of any date of determination, ACNTA; provided,
however, that for purposes of this definition, (1) instead of utilizing prices utilized in
the relevant year end reserve report, Adjusted ACNTA will be calculated using the Three-Year Strip
Price as of such date of determination, (2) ACNTA shall be calculated to give effect to any
acquisitions or dispositions of proved reserves to be consummated on such date of determination and
(3) the reference in the definition of

 

2

ACNTA to “Material Change” shall be deemed to be a reference to a “Significant Change”.

          “Adjusted ACNTA to Indebtedness Ratio” means, at any date of determination, the ratio of (a)
Adjusted ACNTA as of such date of determination to (b) the aggregate amount of Indebtedness of the
Company and its Restricted Subsidiaries as of such date of determination.

          “Adjusted Consolidated Net Tangible Assets” or “ACNTA” means (without duplication), as of the
date of determination:

     (a) the sum of:

     (1) discounted future net revenue from proved crude oil and natural gas reserves of
the Company and its Restricted Subsidiaries calculated in accordance with SEC guidelines
before any state or federal income taxes, as estimated in a reserve report prepared as of
the end of the fiscal year ending prior to the date of determination (or, if the date of
determination is within 45 days after the end of the immediately preceding fiscal year and
no reserve report as of the end of such fiscal year has at the time been prepared, as of
the end of the second preceding fiscal year), which reserve report is prepared or audited
by independent petroleum engineers, as increased by, as of the date of determination, the
discounted future net revenue calculated in accordance with SEC guidelines (utilizing the
prices utilized in such year end reserve report) of:

     (A) estimated proved crude oil and natural gas reserves of the Company and its
Restricted Subsidiaries attributable to acquisitions consummated since the date of
such reserve report, and

     (B) estimated crude oil and natural gas reserves of the Company and its
Restricted Subsidiaries attributable to extensions, discoveries and other additions
and upward determinations of estimates of proved crude oil and natural gas reserves
(including previously estimated development costs incurred during the period and
the accretion of discount since the prior period end) due to exploration,
development or exploitation, production or other activities which reserves were not
reflected in such reserve report;

and decreased by, as of the date of determination, the discounted future net
revenue attributable to:

     (C) estimated proved crude oil and natural gas reserves of the Company and its
Restricted Subsidiaries reflected in such reserve report produced or disposed of
since the date of such reserve report, and

     (D) reductions in the estimated oil and natural gas reserves of the Company
and its Restricted Subsidiaries reflected in such reserve report since the date of
such reserve report attributable to downward

 

3

determinations of estimates of proved
crude oil and natural gas reserves due to exploration, development or exploitation,
production or other activities conducted or otherwise occurring since the date of
such reserve report;

provided, however, that, in the case of each of the determinations made
pursuant to clauses (A) through (D), such increases and decreases shall be estimated by the
Company’s engineers in accordance with customary reserve engineering practices, except that
if as a result of such acquisitions, dispositions, discoveries, extensions or revisions,
there is a Material Change, then such increases and decreases in the discounted future net
revenue shall be confirmed in writing by an independent petroleum engineer;

     (2) the capitalized costs that are attributable to crude oil and natural gas
properties of the Company and its Restricted Subsidiaries to which no proved crude oil and
natural gas reserves are attributed, based on the Company’s books and records as of a date
no earlier than the end of the most recent fiscal quarter for which internal financial
statements of the Company have been made available prior to the date of determination;

     (3) the Net Working Capital as of the end of the most recent fiscal quarter for which
internal financial statements of the Company have been made available prior to the date of
determination; and

     (4) the greater of (i) the net book value as of a date no earlier than the end of the
most recent fiscal quarter for which internal financial statements of the Company have been
made available prior to the date of determination and (ii) the appraised value, as
estimated by independent appraisers, of other tangible assets of the Company and its
Restricted Subsidiaries as of a date within the immediately preceding twelve months
(provided, however, that the Company shall not be required to obtain such
an appraisal of such assets if no such appraisal has, been performed); minus

     (b) to the extent not otherwise taken into account in the immediately preceding clause
(a), the sum of

     (1) minority interests;

     (1) if the Company or any Restricted Subsidiary has Incurred any Indebtedness since
the beginning of such period that remains outstanding or if the transaction giving rise to
the need to calculate the Consolidated Coverage Ratio is an Incurrence of Indebtedness, or

giving effect on a pro forma basis to such Indebtedness as if such Indebtedness had been
Incurred on the first day of such period;

     (2) if the Company or any Restricted Subsidiary has repaid, repurchased, defeased or
otherwise discharged any Indebtedness since the beginning of such period or if any
Indebtedness is to be repaid, repurchased, defeased or otherwise discharged (in each case
other than Indebtedness Incurred under any revolving credit facility unless such
Indebtedness has been permanently repaid) on the date of the transaction giving rise to the
need to calculate the Consolidated Coverage Ratio, EBITDA and Consolidated Interest Expense
for such period shall be calculated on a pro forma basis as if such discharge had occurred
on the first day of such period and as if the Company or such Restricted Subsidiary had not
earned the interest income actually earned during such period in respect of cash or
Temporary Cash Investments used to repay, repurchase, defease or otherwise discharge
such Indebtedness;

     (3) if since the beginning of such period the Company or any Restricted Subsidiary
shall have made any Asset Disposition, EBITDA for such period shall be reduced by an amount
equal to EBITDA (if positive) directly attributable to the assets which are the subject of

merger or otherwise) shall have made an Investment in any Restricted Subsidiary (or any
Person which becomes a Restricted Subsidiary) or an acquisition of assets, including any
acquisition of assets occurring in connection with a transaction requiring a calculation to
be made hereunder, which constitutes producing oil and gas properties or all or
substantially all of an operating unit of a business, EBITDA and Consolidated Interest
Expense for such period shall be calculated after giving pro forma effect thereto
(including the Incurrence of any Indebtedness) as if such Investment or acquisition had
occurred on the first day of such period; and

     (5) if since the beginning of such period any Person (that subsequently became a
Restricted Subsidiary or was merged with or into the Company or any Restricted Subsidiary
since the beginning of such period) shall have made any Asset Disposition, any Investment
or acquisition of assets that would have required an adjustment pursuant to clause (3) or
(4) above if made by the Company or a Restricted Subsidiary during such period, EBITDA and
Consolidated Interest Expense for such period shall be calculated after giving pro forma
effect thereto as if such Asset Disposition, Investment or acquisition had occurred on the
first day of such period.

          For purposes of this definition, whenever pro forma effect is to be given to an acquisition of
assets, the amount of income or earnings relating thereto and the amount of Consolidated Interest
Expense associated with any Indebtedness Incurred in connection therewith, the pro forma
calculations shall be determined in good faith by a responsible financial or accounting Officer of
the Company. If any Indebtedness bears a floating rate of interest and is being given pro forma
effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the date of determination had
been the applicable rate for the entire period (taking into account any Interest Rate Agreement
applicable to such Indebtedness if such Interest Rate Agreement has a remaining term in excess of
12 months).

          If any Indebtedness is Incurred under a revolving credit facility and is being given pro forma
effect, the interest on such Indebtedness shall be calculated based on the average daily balance of
such Indebtedness for the four fiscal quarters subject to the pro forma calculation to the extent
that such Indebtedness was Incurred solely for working capital purposes.

The Securities

          SECTION 2.01. Form and Dating. Provisions relating to the Initial Securities, the
Private Exchange Securities and the Exchange Securities are set forth in the Rule 144A/Regulation
S/IAI Appendix attached hereto (the “Appendix”) which is hereby incorporated in, and expressly made
part of, this Indenture. The Initial Securities and the Trustee’s certificate of authentication
shall be substantially in the form of Exhibit 1 to the Appendix which is hereby incorporated in,
and expressly made a part of, this Indenture. The Exchange Securities, the Private Exchange
Securities and the Trustee’s certificate of authentication shall be substantially in the form of
Exhibit A, which is hereby incorporated in and expressly made a part of this Indenture. The
Securities may have notations, legends or endorsements required by law, stock exchange rule,
agreements to which the Issuers are subject, if any, or usage (provided that any such notation,
legend or endorsement is in a form acceptable to the Company).
Each Security

 

 

37

shall be dated the
date of its authentication. The terms of the Securities set forth in the Appendix and Exhibit A
are part of the terms of this Indenture.

          SECTION 2.02. Execution and Authentication. Two Officers shall sign the Securities
for each of the Issuers by manual or facsimile signature.

          If an Officer whose signature is on a Security no longer holds that office at the time the
Trustee authenticates the Security, the Security shall be valid nevertheless.

          A Security shall not be valid until an authorized signatory of the Trustee manually signs the
certificate of authentication on the Security. The signature shall be conclusive evidence that the
Security has been authenticated under this Indenture.

          The Trustee may appoint an authenticating agent reasonably acceptable to the Company to
authenticate the Securities. Unless limited by the terms of such appointment, an authenticating
agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture
to authentication by the Trustee includes authentication by such agent. An authenticating agent
has the same rights as any Registrar, Paying Agent or agent for service of notices and demands.

          SECTION 2.03. Registrar and Paying Agent. The Issuers shall maintain an office or
agency where Securities may be presented for registration of transfer or for exchange (the
“Registrar”) and an office or agency where Securities may be presented for payment (the “Paying
Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange.
The Issuers may have one or more co-registrars and one or more additional paying agents. The term
“Paying Agent” includes any additional paying agent.

          The Issuers shall enter into an appropriate agency agreement with any Registrar, Paying Agent
or co-registrar not a party to this Indenture, which shall
incorporate the terms of the TIA. The agreement shall implement the provisions of this
Indenture that relate to such agent. The Company shall notify the Trustee of the name and address
of any such agent. If the Issuers fail to maintain a Registrar or Paying Agent, the Trustee shall
act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07.
The Company or any Wholly Owned Subsidiary incorporated or organized within The United States of
America may act as Paying Agent, Registrar, co-registrar or transfer agent.

          The Issuers initially appoint the Trustee as Registrar and Paying Agent in connection with the
Securities.

          SECTION 2.04. Paying Agent To Hold Money in Trust. Prior to each due date of the
principal and interest on any Security, the Issuers shall deposit with the Paying Agent a sum
sufficient to pay such principal and interest when so becoming due. The Issuers shall require each
Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust
for the benefit of Securityholders or the Trustee all money held by the Paying Agent for the
payment of principal of or interest on the Securities and shall notify the Trustee of any default
by the Issuers in making any such

 

 

38

payment. If the Company or a Subsidiary acts as Paying Agent, it
shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The
Issuers at any time may require a Paying Agent to pay all money held by it to the Trustee and to
account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying
Agent shall have no further liability for the money delivered to the Trustee.

          SECTION 2.05. Securityholder Lists. The Trustee shall preserve in as current a form
as is reasonably practicable the most recent list available to it of the names and addresses of
Securityholders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in
writing at least five Business Days before each interest payment date and at such other times as
the Trustee may request in writing, a list in such form and as of such date as the Trustee may
reasonably require of the names and addresses of Securityholders.

          SECTION 2.06. Transfer and Exchange. The Securities shall be issued in registered
form and shall be transferable only upon the surrender of a Security for registration of transfer.
When a Security is presented to the Registrar or a co-registrar with a request to register a
transfer, the Registrar shall register the transfer as requested if the requirements of this
Indenture and Section 8-401(1) of the Uniform Commercial Code are met. When Securities are
presented to the Registrar or a co-registrar with a request to exchange them for an equal principal
amount of Securities of other denominations, the Registrar shall make the exchange as requested if
the same requirements are met. To permit registration of transfers and exchanges, the Issuers
shall execute and the Trustee shall authenticate Securities at the Registrar’s or co-registrar’s
request. The Company may require payment of a sum sufficient to pay all taxes, assessments or
other governmental charges in connection with any transfer or exchange pursuant to this Section
(other than any such transfer taxes, assessments or similar governmental charge payable upon
exchange or transfer pursuant to Sections 3.06, 4.10
and 9.05). The Issuers shall not be required to make and the Registrar need not register
transfers or exchanges of Securities selected for redemption (except, in the case of Securities to
be redeemed in part, the portion thereof not to be redeemed) or any Securities for a period of 15
days before a selection of Securities to be redeemed or 15 days before an interest payment date.

          Prior to the due presentation for registration of transfer of any Security, the Issuers, the
Subsidiary Guarantors, the Trustee, the Paying Agent, the Registrar or any co-registrar may deem
and treat the person in whose name a Security is registered as the absolute owner of such Security
for the purpose of receiving payment of principal of and interest on such Security and for all
other purposes whatsoever, whether or not such Security is overdue, and none of the Issuers, the
Subsidiary Guarantors, the Trustee, the Paying Agent, the Registrar or any co-registrar shall be
affected by notice to the contrary.

          SECTION 2.07. Replacement Securities. If a mutilated Security is surrendered to the
Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or
wrongfully taken, the Issuers shall issue and the Trustee shall authenticate a replacement Security
if the requirements of Section 8-405 of the Uniform Commercial Code are met and the Holder
satisfies any other reasonable requirements of

 

 

39

the Issuers, the Subsidiary Guarantors and the
Trustee. If required by the Trustee or the Issuers, such Holder shall furnish an indemnity bond
sufficient in the judgment of the Issuers and the Trustee to protect the Issuers, the Subsidiary
Guarantors, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss which
any of them may suffer if a Security is replaced. The Issuers and the Trustee may charge the
Holder for their expenses in replacing a Security.

          Every replacement Security is an additional Obligation of the Issuers.

          SECTION 2.08. Outstanding Securities. Securities outstanding at any time are all
Securities authenticated by the Trustee except for those canceled by it, those delivered to it for
cancellation and those described in this Section as not outstanding. A Security does not cease to
be outstanding because the Company or an Affiliate of the Company holds the Security.

          If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the
Trustee and the Issuers receive proof satisfactory to them that the replaced Security is held by a
protected purchaser (as defined in Section 8-303 of the Uniform Commercial Code).

          If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a
redemption date or maturity date money sufficient to pay all principal and interest payable on that
date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case
may be, then on and after that date such Securities (or portions thereof) cease to be outstanding
and interest on them ceases to accrue.

          SECTION 2.09. Temporary Securities. Until definitive Securities are ready for
delivery, the Issuers may prepare and the Trustee shall authenticate temporary Securities.
Temporary Securities shall be substantially in the form of definitive Securities but may have
variations that the Issuers consider appropriate for temporary Securities. Without unreasonable
delay, the Issuers shall prepare and the Trustee shall authenticate definitive Securities and
deliver them in exchange for temporary Securities.

          SECTION 2.10. Cancellation. The Issuers at any time may deliver Securities to the
Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any
Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and
no one else shall cancel and destroy (subject to the record retention requirements of the Exchange
Act) all Securities surrendered for registration of transfer, exchange, payment or cancellation and
deliver a certificate of such destruction to the Company unless the Company directs the Trustee to
deliver canceled Securities to the Company. The Issuers may not issue new Securities to replace
Securities they have redeemed, paid or delivered to the Trustee for cancellation.

          SECTION 2.11. Defaulted Interest. If the Issuers default in a payment of interest on
the Securities, the Issuers shall pay defaulted interest at the rate per annum shown on the
Security (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The
Issuers may pay the defaulted interest to the persons who are

 

 

40

Securityholders on a subsequent
special record date. The Company shall fix or cause to be fixed any such special record date and
payment date to the reasonable satisfaction of the Trustee and shall promptly mail to each
Securityholder a notice that states the special record date, the payment date and the amount of
defaulted interest to be paid.

          SECTION 2.12. CUSIP Numbers, ISINs, etc. The Issuers in issuing the Securities may
use “CUSIP” numbers, ISINs and “Common Code” numbers (in each case if then generally in use) and,
if so, the Trustee shall use “CUSIP” numbers, ISINs and “Common Code” numbers in notices of
redemption as a convenience to Holders; provided, however, that any such notice may
state that no representation is made as to the correctness of such numbers either as printed on the
Securities or as contained in any notice of a redemption and that reliance may be placed only on
the other identification numbers printed on the Securities, and any such redemption shall not be
affected by any defect in or omission of such numbers. The Company shall advise the Trustee in
writing of any change in any “CUSIP” numbers, ISINs or “Common Code” numbers applicable to the
Securities.

          SECTION 2.13. Issuance of Additional Securities. After the Issue Date, the Issuers
shall be entitled, subject to their compliance with Section 4.03, to issue Additional Securities
under this Indenture, which Securities shall have identical terms as the Initial Securities issued
on the Issue Date, other than with respect to the date of issuance and issue price. All the
Securities issued under this Indenture shall be treated as a single class for all purposes of this
Indenture including waivers, amendments, redemptions and offers to purchase.

          With respect to any Additional Securities, the Company and PELLC shall set forth in
resolutions of the Board of Directors and the governing body of PELLC, respectively, and an
Officers’ Certificate, a copy of each which shall be delivered to the Trustee, the following
information:

     (1) the aggregate principal amount of such Additional Securities to be authenticated
and delivered pursuant to this Indenture and the provision of Section 4.03 that the Issuers
are relying on to issue such Additional Securities;

     (2) the issue price, the issue date and the CUSIP number of such Additional
Securities; provided, however, that no Additional Securities may be issued
at a price that would cause such Additional Securities to have “original issue discount”
within the meaning of Section 1273 of the Code; and

     (3) whether such Additional Securities shall be Initial Securities or shall be issued
in the form of Exchange Securities as set forth in Exhibit A.

ARTICLE 3

Redemption

          SECTION 3.01. Notices to Trustee. If the Issuers elect to redeem Securities pursuant
to paragraph 5 of the Securities, the Company shall, on its behalf and
on behalf of PELLC, notify the Trustee in writing of the redemption date, the principal amount
of Securities to be redeemed and the paragraph of the Securities pursuant to which the redemption
will occur.

          The Company shall give the notice to the Trustee provided for in this Section at least 45 days
before the redemption date unless the Trustee consents to a shorter period. Such notice shall be
accompanied by an Officers’ Certificate and an Opinion of Counsel from the Company to the effect
that such redemption will comply with the conditions herein.

          SECTION 3.02. Selection of Securities To Be Redeemed. If fewer than all the
Securities are to be redeemed, the Trustee shall select the Securities to be redeemed pro rata to
the extent practicable. The Trustee shall make the selection from outstanding Securities not
previously called for redemption. Securities and portions of them the Trustee selects shall be in
principal amounts of $1,000 or a whole multiple of $1,000. Provisions of this Indenture that
apply to Securities called for redemption also apply to portions of Securities called for
redemption. The Trustee shall notify the Company promptly of the Securities or portions of
Securities to be redeemed.

          SECTION 3.03. Notice of Redemption. At least 30 days but not more than 60 days before
a date for redemption of Securities, the Issuers shall mail a notice of redemption by first-class
mail to each Holder of Securities to be redeemed at such Holder’s registered address.

     The notice shall identify the Securities to be redeemed and shall state:

     (1) the redemption date;

     (2) the redemption price;

     (3) the name and address of the Paying Agent;

     (4) that Securities called for redemption must be surrendered to the Paying Agent to
collect the redemption price;

     (5) if fewer than all the outstanding Securities are to be redeemed, the
identification and principal amounts of the particular Securities to be redeemed;

 

 

42

     (6) that, unless the Issuers default in making such redemption payment, interest on
Securities (or portion thereof) called for redemption ceases to accrue on and after the
redemption date;

     (7) the “CUSIP” number, ISIN or “Common Code” number, if any, printed on the
Securities being redeemed; and

     (8) that no representation is made as to the correctness or accuracy of the “CUSIP”
number, ISIN, or “Common Code” number, if any, listed in such notice or printed on the
Securities.

          At the Company’s request, the Trustee shall give the notice of redemption in the Issuers’
names and at the Issuers’ expense. In such event, the Issuers shall provide the Trustee with the
information required by this Section.

          SECTION 3.04. Effect of Notice of Redemption. Once notice of redemption is mailed,
Securities called for redemption become due and payable on the redemption date and at the
redemption price stated in the notice and from and after such redemption date (unless the Company
defaults in the payment of the redemption price and accrued and unpaid interest), such Securities
will cease to bear interest. Upon surrender to the Paying Agent, such Securities shall be paid at
the redemption price stated in the notice, plus accrued interest to the redemption date (subject to
the right of Holders of record on the relevant record date to receive interest due on the related
interest payment date), and such Securities shall be canceled by the Trustee. Failure to give
notice or any defect in the notice to any Holder shall not affect the validity of the notice to any
other Holder.

          SECTION 3.05. Deposit of Redemption Price. Prior to the redemption date, the Issuers
shall deposit with the Paying Agent (or, if the Company or a Subsidiary is the Paying Agent, shall
segregate and hold in trust) money sufficient to pay the redemption price of and accrued interest
on all Securities to be redeemed on that date other than Securities or portions of Securities
called for redemption which have been delivered by the Company to the Trustee for cancellation.

          SECTION 3.06. Securities Redeemed in Part. Upon surrender of a Security that is
redeemed in part, the Issuers shall execute and the Trustee shall authenticate for the Holder (at
the Issuers’ expense) a new Security equal in principal amount to the unredeemed portion of the
Security surrendered.

          The Issuers shall pay interest on overdue principal at the rate specified therefor in the

Securityholders with such annual and other reports as are specified in Sections 13 and 15(d)
of the Exchange Act and applicable to a U.S. Person subject to such Sections, such reports to be so

containing all the information, audit reports and exhibits required for such reports. If at any
time, the Issuers are not subject to the periodic reporting requirements of the Exchange Act for
any reason, the Issuers shall nevertheless continue filing the reports specified in the preceding
sentence with the SEC within the time periods required unless the SEC shall not accept such a
filing. The Issuers agree that they shall not take any action for the purpose of causing the SEC
not to accept any such filings. If, notwithstanding the foregoing, the SEC shall not accept such
filings for any reason, the Issuers shall post the reports specified in the preceding sentence on
the Company’s website within the time periods that would apply if the Issuers were required to file
those reports with the SEC. At any time that any of the Company’s Subsidiaries are Unrestricted
Subsidiaries, then, unless the operations, assets, liabilities and cash flows of the Unrestricted
Subsidiaries are, in aggregate, immaterial, the quarterly and annual financial information required
by the preceding paragraph shall include a reasonably detailed presentation, either on the face of
the financial statements or in the footnotes thereto, and in “Management’s Discussion and Analysis
of Financial Condition and Results of Operations”, of the financial condition and results of
operations of the Company and its Restricted Subsidiaries separate from the financial condition and
results of operations of the Unrestricted Subsidiaries of the Company.

          In addition, the Issuers shall furnish to the Holders of the Securities and to prospective
investors, upon the requests of such Holders, any information required to be delivered pursuant to

4.06(a)(3)(A) and (B) 20% of ACNTA;

     (2) Indebtedness owed to and held by the Company or a Restricted Subsidiary;
provided, however, that (A) any subsequent issuance or transfer of
any Capital Stock which results in any such Restricted Subsidiary ceasing to be a
Restricted Subsidiary or any subsequent transfer of such Indebtedness (other than to the
Company or a Restricted Subsidiary) shall be deemed, in each case, to constitute the
Incurrence of such Indebtedness by the obligor thereon, (B) if either Issuer is the obligor
on such Indebtedness and the holder of such Indebtedness is neither an Issuer nor a
Subsidiary Guarantor, such Indebtedness is expressly subordinated in right of payment to
all obligations with respect to the Securities, and (C) if a Subsidiary Guarantor is the
obligor on such Indebtedness and the holder of such Indebtedness is neither an Issuer nor a
Subsidiary Guarantor, such Indebtedness is expressly subordinated in right of payment to

provided further, however, that the Existing Second Lien Term Loan shall
not be Refinanced pursuant to this Section 4.03(b)(6);

unless such Indebtedness shall be subordinated to the Securities or the applicable Subsidiary
Guaranty to at least the same extent as such Subordinated Obligations.

          (d) For purposes of determining compliance with this Section 4.03:

     (1) any Indebtedness remaining outstanding under the Credit Agreement after the
application of the net proceeds from the sale of the Securities on the Issue Date shall be
treated as Incurred on the Issue Date under Section 4.03(b)(1);

sole discretion, shall classify such item of Indebtedness (or any portion thereof) at the
time of Incurrence and shall only be required to include the amount and type of such
Indebtedness in one of the above clauses; provided, however, that any
Indebtedness originally classified as Incurred pursuant to
Section 4.03(b)(13) may later be reclassified as having been Incurred pursuant to

     (D) the amount by which Indebtedness is reduced on the Company’s consolidated
balance sheet upon the conversion or exchange (other than by a Subsidiary of the
Company) subsequent to the Issue Date of any Indebtedness convertible or
exchangeable for Capital Stock (other than Disqualified Stock) of the Company (plus
the amount of any accrued interest then outstanding on such Indebtedness to the
extent the obligation to pay such interest is extinguished less the amount of any
cash, or the Fair Market Value of any property, distributed by the Company upon

amount shall not exceed the Net Cash Proceeds received by the Company or any
Restricted Subsidiary from the sale of such Indebtedness (excluding Net Cash

such Person or Unrestricted Subsidiary, the amount of Investments (excluding
Permitted Investments) previously made (and treated as a Restricted Payment) by the
Company or any Restricted Subsidiary in such Person or Unrestricted Subsidiary,
such excess shall not be included in this clause (E) unless the amount represented
by such excess has not been and shall not be taken into account in one of the

the date the Company or Restricted Subsidiary became legally or contractually obligated to
make such Restricted Payment (including the declaration of a dividend), if at the date of
becoming so legally or contractually bound, such Restricted Payment would have complied
with the provisions of this Indenture (and such Restricted Payment shall be deemed to be

(including employment agreements), management equity subscription agreement or stock option
agreements or plans (or amendments thereto), approved by the Board of Directors, under
which such individuals purchase or sell or are granted the right to purchase or sell shares

portion of such period and (2) the Company shall be permitted to rely in good faith on the
financial statements and other financial data derived from the books and records of the Company
that are available on the date of determination.

this Section 4.05 or this clause (C); provided, however, that the
encumbrances and restrictions with respect to such Restricted Subsidiary contained
in any such refinancing agreement or amendment are not materially less favorable,
taken as a whole, to the Securityholders than encumbrances and restrictions with
respect to such Restricted Subsidiary contained in such predecessor agreements;

     (D) any encumbrance or restriction with respect to a Restricted Subsidiary
imposed pursuant to an agreement entered into for the sale or

          (2) with respect to clause (c) only,

     (A) any encumbrance or restriction consisting of customary subletting,
nonassignment or transfer provisions in leases, licenses, similar agreements,
operating agreements or other agreements customary in the Oil and Gas Business to
the extent such provisions restrict the transfer of the lease, license or similar
agreement or the property subject thereto; and

     (B) any encumbrance or restriction contained in security agreements or
mortgages securing Indebtedness to the extent such encumbrance or restriction
restricts the transfer of the property subject to such security agreements or
mortgages.

          SECTION 4.06. Limitation on Sales of Assets and Subsidiary Stock. (a) The Company
shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate
any Asset Disposition unless:

     (1) the Company or such Restricted Subsidiary receives consideration at the time of
such Asset Disposition at least equal to the Fair Market Value of the shares and assets
subject to such Asset Disposition;

     (2) at least 75% of the consideration thereof received by the Company or such
Restricted Subsidiary is in the form of cash or cash equivalents; and

     (3) an amount equal to 100% of the Net Available Cash from such Asset Disposition is
applied by the Company (or such Restricted Subsidiary, as the case may be)

     (A) first, to the extent the Company elects (or is required by the
terms of any Indebtedness), to prepay, repay, redeem or purchase Senior
Indebtedness of either of the Issuers or of a Subsidiary Guarantor or any
Indebtedness (other than any Disqualified Stock) of any Restricted Subsidiary that
is neither PetroQuest L.L.C. nor a Subsidiary Guarantor (in each case other than
Indebtedness owed to the Company or an Affiliate of the Company) within one year
from the later of the date of such Asset Disposition or the receipt of such Net
Available Cash;

     (B) second, to the extent of the balance of such Net Available Cash
after application in accordance with clause (A), to the extent the Company
elects, to acquire Additional Assets or to make capital expenditures in the
Oil and Natural Gas Business within one year from the later of the date of such
Asset Disposition or the receipt of such Net Available Cash; and

     (C) third, to the extent of the balance of such Net Available Cash
after application in accordance with Section 4.06(a)(3)(A) and (B), to make an
offer to the holders of the Securities (and to holders of other Senior Indebtedness
of the Issuers or of a Subsidiary Guarantor designated by the Company) to purchase
Securities (and such other Senior Indebtedness of the Issuers or of a Subsidiary
Guarantor) pursuant to and subject to the conditions contained in this Indenture;
provided, however, that in connection with any prepayment,
repayment or purchase of Indebtedness pursuant to Section 4.06(a)(3)(A) or this
Section 4.06(a)(3)(C), the Company or such Restricted Subsidiary shall permanently
retire such Indebtedness and shall cause the related loan commitment (if any) to be
permanently reduced in an amount equal to the principal amount so prepaid, repaid
or purchased.

          Notwithstanding the foregoing provisions of this Section, the Company and the Restricted
Subsidiaries shall not be required to apply any Net Available Cash in

 

 

53

accordance with this Section
except to the extent that the aggregate Net Available Cash from all Asset Dispositions which is not
applied in accordance with this Section exceeds $10.0 million. Pending application of Net
Available Cash pursuant to this Section, such Net Available Cash shall be invested in Temporary
Cash Investments or applied to temporarily reduce revolving credit indebtedness.

          For the purposes of this Section, the following are deemed to be cash or cash equivalents:

     (1) the assumption or discharge of Senior Indebtedness of the Issuers or of a
Subsidiary Guarantor (other than obligations in respect of Disqualified Stock of the
Issuers) or any Indebtedness of any Restricted Subsidiary that is neither PetroQuest L.L.C.
nor a Subsidiary Guarantor (other than obligations in respect of Disqualified Stock of such
Restricted Subsidiary) and the release of the Issuers, Subsidiary Guarantor or such
Restricted Subsidiary from all liability on such Indebtedness in connection with such Asset
Disposition; and

     (2) securities received by the Company or any Restricted Subsidiary from the
transferee that are promptly converted by the Company or such Restricted Subsidiary into
cash, to the extent of cash received in that conversion.

          (b) In the event of an Asset Disposition that requires the purchase of Securities (and other
Senior Indebtedness of the Issuers or of a Subsidiary Guarantor) pursuant to Section 4.06(a)(3)(C),
the Issuers shall purchase Securities tendered pursuant to an offer by the Issuers for the
Securities (and such other Senior Indebtedness) at a purchase price of 100% of their principal
amount (or, in the event such other Senior Indebtedness was issued with significant original issue
discount, 100% of the accreted
value thereof) without premium, plus accrued but unpaid interest (or, in respect of such other
Senior Indebtedness, such lesser price, if any, as may be provided for by the terms of such Senior
Indebtedness) in accordance with the procedures (including prorating in the event of
oversubscription) set forth in Section 4.06(c). If the aggregate purchase price of the securities
tendered exceeds the Net Available Cash allotted to their purchase, the Issuers shall select the
securities to be purchased on a pro rata basis but in round denominations, which in the case of the
Securities shall be denominations of $1,000 principal amount or multiples thereof. The Issuers
shall not be required to make such an offer to purchase Securities pursuant to this Section if the
Net Available Cash available therefor (and for the purchase of such other Senior Indebtedness) is
less than $10.0 million (which lesser amount shall be carried forward for purposes of determining
whether such an offer is required with respect to the Net Available Cash from any subsequent Asset
Disposition). Upon completion of such an offer to purchase, Net Available Cash shall be deemed to
be reduced by the aggregate amount of such offer.

          (c) (1) Promptly, and in any event within 10 days after the Issuers become obligated to make
an Offer, the Issuers shall deliver to the Trustee and send, by first-class mail to each Holder, a
written notice stating that the Holder may elect to have his Securities purchased by the Issuers
either in whole or in part (subject to prorating as described in Section 4.06(b) in the event the
Offer is oversubscribed) in integral multiples

 

 

54

of $1,000 of principal amount, at the applicable
purchase price. The notice shall specify a purchase date not less than 30 days nor more than 60
days after the date of such notice (the “Purchase Date”) and shall contain such information
concerning the business of the Company which the Company in good faith believes will enable such
Holders to make an informed decision (which at a minimum will include (A) the most recently filed
Annual Report on Form 10-K (including audited consolidated financial statements) of the Company,
the most recent subsequently filed Quarterly Report on Form 10-Q and any Current Report on Form 8-K
of the Company filed subsequent to such Quarterly Report, other than Current Reports describing
Asset Dispositions otherwise described in the offering materials (or corresponding successor
reports), (B) a description of material developments in the Company’s business subsequent to the
date of the latest of such Reports, and (C) if material, appropriate pro forma
financial information) and all instructions and materials necessary to tender Securities pursuant
to the Offer, together with the information contained in clause (3).

          (2) Not later than the date upon which written notice of an Offer is delivered to the Trustee
as provided below, the Company shall deliver to the Trustee an Officers’ Certificate as to (A) the
amount of the Offer (the “Offer Amount”), including information as to any other Senior Indebtedness
included in the Offer, (B) the allocation of the Net Available Cash from the Asset Dispositions
pursuant to which such Offer is being made and (C) the compliance of such allocation with the
provisions of Section 4.06(a) and (b). On such date, the Issuers shall also irrevocably deposit
with the Trustee or with a Paying Agent (or, if either Issuer is acting as Paying Agent, segregate
and hold in trust) in Temporary Cash Investments, maturing on or before the last day prior to the
Purchase Date or on the Purchase Date if funds are immediately available by open of business, an
amount equal to the Offer Amount to be held for payment in accordance with the provisions of this
Section. If the Offer includes other Senior
Indebtedness, the deposit described in the preceding sentence may be made with any other
paying agent pursuant to arrangements satisfactory to the Trustee. Upon the expiration of the
period for which the Offer remains open (the “Offer Period”), the Company shall deliver to the
Trustee for cancellation the Securities or portions thereof which have been properly tendered to
and are to be accepted by the Issuers. The Trustee shall, on the Purchase Date, mail or deliver
payment (or cause the delivery of payment) to each tendering Holder in the amount of the purchase
price. In the event that the aggregate purchase price of the Securities delivered by the Company
to the Trustee is less than the Offer Amount applicable to the Securities, the Trustee shall
deliver the excess to the Issuers immediately after the expiration of the Offer Period.

          (3) Holders electing to have a Security purchased shall be required to surrender the
Security, with an appropriate form duly completed, to the Issuers at the address specified in the
notice at least three Business Days prior to the Purchase Date. Holders shall be entitled to
withdraw their election if the Trustee or the Company receives not later than one Business Day
prior to the Purchase Date, a telex, facsimile transmission or letter setting forth the name of the
Holder, the principal amount of the Security which was delivered for purchase by the Holder and a
statement that such Holder is withdrawing his election to have such Security purchased. Holders
whose

 

 

55

Securities are purchased only in part shall be issued new Securities equal in principal
amount to the unpurchased portion of the Securities surrendered.

          (4) At the time the Company delivers Securities to the Trustee which are to be accepted for
purchase, the Company shall also deliver an Officers’ Certificate stating that such Securities are
to be accepted by the Company pursuant to and in accordance with the terms of this Section. A
Security shall be deemed to have been accepted for purchase at the time the Trustee, directly or
through an agent, mails or delivers payment therefor to the surrendering Holder.

          (d) The Issuers shall comply, to the extent applicable, with the requirements of Section 14(e)
of the Exchange Act and any other securities laws or regulations in connection with the repurchase
of Securities pursuant to this Section. To the extent that the provisions of any securities laws
or regulations conflict with provisions of this Section, the Issuers shall comply with the
applicable securities laws and regulations and shall not be deemed to have breached its obligations
under this Section by virtue of its compliance with such securities laws or regulations.

          SECTION 4.07. Limitation on Affiliate Transactions. (a) The Company shall not, and
shall not permit any Restricted Subsidiary to, enter into or permit to exist any transaction
(including the purchase, sale, lease or exchange of any property, employee compensation
arrangements or the rendering of any service) with, or for the benefit of, any Affiliate of the
Company (an “Affiliate Transaction”) unless:

     (1) the terms of the Affiliate Transaction are no less favorable to the Company or
such Restricted Subsidiary than those that could be obtained at the time of the Affiliate
Transaction in arm’s-length dealings with a Person who is not an Affiliate;

     (2) if such Affiliate Transaction involves an amount in excess of $5.0 million, the
terms of the Affiliate Transaction are set forth in writing and a majority of the directors
of the Company disinterested with respect to such Affiliate Transaction have determined in
good faith that the criteria set forth in clause (1) are satisfied and have approved the
relevant Affiliate Transaction as evidenced by a resolution of the Board of Directors; and

     (3) if such Affiliate Transaction involves an amount in excess of $15.0 million, the
Board of Directors shall also have received a written opinion from an Independent Qualified
Party to the effect that such Affiliate Transaction is fair, from a financial standpoint,
to the Company and its Restricted Subsidiaries or is not less favorable to the Company and
its Restricted Subsidiaries than could reasonably be expected to be obtained at the time in
an arm’s-length transaction with a Person who was not an Affiliate.

     (b) The provisions of Section 4.07(a) shall not prohibit:

 

 

56

     (1) any Investment (other than a Permitted Investment) or other Restricted Payment, in
each case permitted to be made pursuant to Section 4.04(a);

     (2) any employment agreement or other employee compensation plan or arrangement in
existence on the Issue Date or entered into thereafter in the ordinary course of business
including any issuance of securities, or other payments, awards or grants in cash,
securities or otherwise pursuant to, or the funding of, employment arrangements, stock
options and stock ownership plans approved by the Board of Directors;

     (3) loans or advances to employees in the ordinary course of business in accordance
with the past practices of the Company or its Restricted Subsidiaries, but in any event not
to exceed $1.0 million in the aggregate outstanding at any one time;

     (4) the payment of reasonable fees to directors of the Company and its Restricted
Subsidiaries who are not employees of the Company or its Restricted Subsidiaries;

     (5) any transaction with the Company, a Restricted Subsidiary or joint venture or
similar entity (excluding an Unrestricted Subsidiary) which would constitute an Affiliate
Transaction solely because the Company or a Restricted Subsidiary owns an equity interest
in or otherwise controls such Restricted Subsidiary, joint venture or similar entity;

     (6) indemnities of officers, directors and employees of the Company or any Restricted
Subsidiary consistent with applicable charter, by-law or statutory provisions;

     (7) the issuance or sale of any Capital Stock (other than Disqualified Stock) of the
Company;

     (8) any transaction with an Unrestricted Subsidiary to the extent such transaction is
in the ordinary course of business of the Company and its Restricted Subsidiaries and of
such Unrestricted Subsidiary; and

     (9) any transaction with Affiliates pursuant to arrangements in existence on the Issue
Date pursuant to which those Affiliates own, or are entitled to acquire, working,
overriding royalty or other similar interests in particular properties operated by the
Company or any Restricted Subsidiary or in which any of the Company or one or more
Restricted Subsidiaries also own an interest.

          SECTION 4.08. Limitation on Line of Business. The Company shall not, and shall not
permit any Restricted Subsidiary, to engage in any material respect in any business other than a
Related Business.

 

 

57

          SECTION 4.09. Limitation on the Sale or Issuance of Capital Stock of Restricted
Subsidiaries. The Company

     (1) shall not, and shall not permit any Restricted Subsidiary to, sell, lease,
transfer or otherwise dispose of any Capital Stock of any Restricted Subsidiary to any
Person (other than the Company or a Wholly Owned Subsidiary), and

     (2) shall not permit any Restricted Subsidiary to issue any of its Capital Stock
(other than, if necessary, shares of its Capital Stock constituting directors’ or other
legally required qualifying shares) to any Person (other than to the Company or a Wholly
Owned Subsidiary),

unless

     (A) immediately after giving effect to such issuance, sale or other
disposition, neither the Company nor any of its Subsidiaries own any Capital Stock
of such Restricted Subsidiary; or

     (B) immediately after giving effect to such issuance, sale or other
disposition, such Restricted Subsidiary would no longer constitute a Restricted
Subsidiary and any Investment in such Person remaining after giving effect thereto
is treated as a new Investment by the Company and such Investment would be
permitted to be made under Section 4.04 if made on the date of such issuance, sale
or other disposition.

          For purposes of this Section 4.09, the creation of a Lien on any Capital Stock of a Restricted
Subsidiary to secure Indebtedness of the Company or any of its Restricted Subsidiaries shall not be
deemed to be a violation of this Section 4.09; provided, however, that any sale or
other disposition by the secured party of such Capital Stock following foreclosure of its Lien
shall be subject to this Section 4.09.

          SECTION 4.10. Change of Control. (a) Upon the occurrence of a Change of Control,
each Holder shall have the right to require that the Issuers purchase
such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount
thereof plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of
holders of record on the relevant record date to receive interest on the relevant interest payment
date), in accordance with the terms contemplated in Section 4.10(b).

          (b) Within 30 days following any Change of Control, the Issuers shall mail a notice to each
Holder with a copy to the Trustee (the “Change of Control Offer”) stating:

     (1) that a Change of Control has occurred and that such Holder has the right to
require the Issuers to purchase such Holder’s Securities at a purchase

 

 

58

price in cash equal
to 101% of the principal amount thereof on the date of purchase, plus accrued and unpaid
interest, if any, to the date of purchase (subject to the right of Holders of record on the
relevant record date to receive interest on the relevant interest payment date);

     (2) the circumstances and relevant facts regarding such Change of Control (including
information with respect to pro forma historical income, cash flow and
capitalization, in each case after giving effect to such Change of Control);

     (3) the purchase date (which shall be no earlier than 30 days nor later than 60 days
from the date such notice is mailed); and

     (4) the instructions, as determined by the Company, consistent with this Section, that
a Holder must follow in order to have its Securities purchased.

          (c) Holders electing to have a Security purchased will be required to surrender the Security,
with an appropriate form duly completed, to the Issuers at the address specified in the notice at
least three Business Days prior to the purchase date. Holders will be entitled to withdraw their
election if the Trustee or the Company receives not later than one Business Day prior to the
purchase date, a telegram, telex, facsimile transmission or letter setting forth the name of the
Holder, the principal amount of the Security which was delivered for purchase by the Holder and a
statement that such Holder is withdrawing his election to have such Security purchased.

          (d) On the purchase date, all Securities purchased by the Issuers under this Section shall be
delivered by the Company to the Trustee for cancellation, and the Issuers shall pay the purchase
price plus accrued and unpaid interest, if any, to the Holders entitled thereto.

          (e) Notwithstanding the foregoing provisions of this Section, the Issuers shall not be
required to make a Change of Control Offer following a Change of Control if a third party makes the
Change of Control Offer in the manner, at the times and otherwise in compliance with the
requirements set forth in this Section applicable to a Change of Control Offer made by the Issuers
and purchases all Securities validly tendered and not withdrawn under such Change of Control Offer.

          (f) The Issuers shall comply, to the extent applicable, with the requirements of Section 14(e)
of the Exchange Act and any other securities laws or regulations in connection with the repurchase
of Securities pursuant to this Section. To the extent that the provisions of any securities laws
or regulations conflict with provisions of this Section, the Issuers shall comply with the
applicable securities laws and regulations and shall not be deemed to have breached its obligations
under this Section by virtue of its compliance with such securities laws or regulations.

          SECTION 4.11. Limitation on Liens. The Company shall not, and shall not permit any
Restricted Subsidiary to, directly or indirectly, Incur or permit to exist any Lien (the “Initial
Lien”) of any nature whatsoever on any of its properties (including

 

 

59

Capital Stock of a Restricted
Subsidiary), whether owned at the Issue Date or thereafter acquired, securing any Indebtedness,
other than Permitted Liens, without effectively providing that the Securities shall be secured
equally and ratably with (or prior to) the obligations so secured for so long as such obligations
are so secured.

          Any Lien created for the benefit of the Holders of the Securities pursuant to the preceding
sentence shall provide by its terms that such Lien shall be automatically and unconditionally
released and discharged upon the release and discharge of the Initial Lien.

          SECTION 4.12. Limitation on Sale/Leaseback Transactions. The Company shall not, and
shall not permit any Restricted Subsidiary to, enter into any Sale/ Leaseback Transaction with
respect to any property unless:

     (1) the Company or such Restricted Subsidiary would be entitled to (A) Incur
Indebtedness in an amount equal to the Attributable Debt with respect to such
Sale/Leaseback Transaction pursuant to Section 4.03 and (B) create a Lien on such property
securing such Attributable Debt without equally and ratably securing the Securities
pursuant to Section 4.11;

     (2) the net proceeds received by the Company or any Restricted Subsidiary in
connection with such Sale/Leaseback Transaction are at least equal to the Fair Market Value
of such property; and

     (3) the Company applies the proceeds of such transaction in compliance with Section
4.06.

          SECTION 4.13. Future Guarantors. The Company shall cause each domestic Restricted
Subsidiary to, and each Foreign Subsidiary that enters into a Guarantee of any Indebtedness of an
Issuer or of a Restricted Subsidiary (other than a Foreign Subsidiary that Guarantees Indebtedness
Incurred by another Foreign Subsidiary) to, in each case, at the same time, execute and deliver to
the Trustee a Guaranty Agreement pursuant to which such Restricted Subsidiary shall Guarantee
payment of the Securities on the same terms and conditions as those set forth in this Indenture.

          SECTION 4.14. Compliance Certificate. The Company shall deliver to the Trustee within
120 days after the end of each fiscal year of the Company an Officers’
Certificate stating that in the course of the performance by the signers of their duties as
Officers of the Company they would normally have knowledge of any Default and whether or not the
signers know of any Default that occurred during such period. If they do, the certificate shall
describe the Default, its status and what action the Company is taking or proposes to take with
respect thereto. The Company also shall comply with TIA § 314(a)(4), the certificate referred to
in such section of the TIA to be delivered to the Trustee within 120 days after the end of each
fiscal year of the Company. For purposes of this Section 4.14, the “fiscal year” of the Company
means a calendar year ending December 31.

 

 

60

          SECTION 4.15. Further Instruments and Acts. Upon request of the Trustee, the Issuers
will execute and deliver such further instruments and do such further acts as may be reasonably
necessary or proper to carry out more effectively the purpose of this Indenture.

ARTICLE 5

Successor Company

          SECTION 5.01. Merger and Consolidation. (a) The Company shall not consolidate with
or merge with or into, or convey, transfer or lease, in one transaction or a series of
transactions, directly or indirectly, all or substantially all its assets to, any Person, unless:

     (1) the resulting, surviving or transferee Person (the “Successor Company”) shall be a
Person organized and existing under the laws of the United States of America, any State
thereof or the District of Columbia and the Successor Company (if not an the Company) shall
expressly assume, by an indenture supplemental thereto, executed and delivered to the
Trustee, in form satisfactory to the Trustee, all the obligations of the Company under the
Securities and this Indenture;

     (2) immediately after giving pro forma effect to such transaction (and treating any
Indebtedness which becomes an obligation of the Successor Company or any Subsidiary as a
result of such transaction as having been Incurred by such Successor Company or such
Subsidiary at the time of such transaction), no Default shall have occurred and be
continuing;

     (3) immediately after giving pro forma effect to such transaction, the Successor
Company would be able to Incur an additional $1.00 of Indebtedness pursuant to Section
4.03(a);

     (4) the Company shall have delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel, each stating that such consolidation, merger or transfer and such
supplemental indenture (if any) comply with this Indenture; and

     (5) the Company shall have delivered to the Trustee an Opinion of Counsel to the
effect that the Holders will not recognize income, gain or loss for Federal income tax
purposes as a result of such transaction and will be subject to Federal income tax on the
same amounts, in the same manner and at the same times as would have been the case if such
transaction had not occurred;

 

 

61

provided, however, that clause (3) shall not be applicable to (A) a Restricted
Subsidiary consolidating with, merging into or transferring all or part of its properties and
assets to the Company, (B) the Company merging with an Affiliate of the Company solely for the
purpose and with the sole effect of reincorporating the Company in another jurisdiction in the
United States or (C) as long as PetroQuest L.L.C. is at the time a Restricted Subsidiary of the
Company, the consolidation or merger of the Company with or into PetroQuest L.L.C. or the transfer
of all or part of the properties of the Company to PetroQuest L.L.C.

          For purposes of this Section 5.01, the sale, lease, conveyance, assignment, transfer or other
disposition of all or substantially all of the properties and assets of one or more Subsidiaries of
the Company, which properties and assets, if held by the Company instead of such Subsidiaries,
would constitute all or substantially all of the properties and assets of the Company on a
consolidated basis, shall be deemed to be the transfer of all or substantially all of the
properties and assets of the Company.

          The Successor Company shall be the successor to the Company and shall succeed to, and be
substituted for, and may exercise every right and power of, the Company under this Indenture, and
the predecessor Company, except in the case of a lease, shall be released from the obligation to
pay the principal of and interest on the Securities.

          (b) The Company shall not permit PetroQuest L.L.C. or any Subsidiary Guarantor to consolidate
with or merge with or into, or convey, transfer or lease, in one transaction or a series of
transactions, all or substantially all of its assets to any Person unless:

     (1) the resulting, surviving or transferee Person (if not PetroQuest L.L.C. or such
Subsidiary, as the case may be) shall be a Person organized and existing under the laws of
the jurisdiction under which PetroQuest L.L.C. or such Subsidiary was organized or under
the laws of the United States of America, or any State thereof or the District of Columbia,
and such Person (if not PetroQuest L.L.C. or such Subsidiary Guarantor) shall expressly
assume, by a supplemental indenture (if such Person is consolidating or merging with, or
acquiring all or substantially all the assets of, PetroQuest L.L.C.) or by a Guaranty
Agreement (if such Person is consolidating or merging with, or acquiring all or
substantially all the assets of, any Subsidiary Guarantor), all the obligations of
PetroQuest L.L.C. under this Indenture or of such Subsidiary, if any, under its Subsidiary
Guaranty, as the case may be; provided, however, that the foregoing shall not apply
in the case of a Subsidiary Guarantor (x) that has been disposed of in its entirety to
another Person (other than to the Company or an Affiliate of the Company),
whether through a merger, consolidation or sale of Capital Stock or assets or (y)
that, as a result of the disposition of all or a portion of its Capital Stock, ceases to be
a Subsidiary, in both cases, if in connection therewith the Company provides an Officers’
Certificate to the Trustee to the effect that the Company shall comply with its obligations
under Section 4.06 in respect of such disposition;

 

 

62

     (2) immediately after giving effect to such transaction or transactions on a pro forma
basis (and treating any Indebtedness which becomes an obligation of the resulting,
surviving or transferee Person as a result of such transaction as having been issued by
such Person at the time of such transaction), no Default shall have occurred and be
continuing; and

     (3) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that such consolidation, merger or transfer and such supplemental
indenture or Guaranty Agreement, if any, complies with this Indenture.

ARTICLE 6

Significant Subsidiary in an involuntary case;

     (B) appoints a Custodian of the Company, PELLC, any Subsidiary Guarantor or
any Significant Subsidiary or for any substantial part of its property; or

     (C) orders the winding up or liquidation of the Company, PELLC, any Subsidiary
Guarantor or any Significant Subsidiary;

or any similar relief is granted under any foreign laws and the order or decree remains
unstayed and in effect for 60 days;

     (9) any judgment or decree for the payment of money in excess of $5 million or its
foreign currency equivalent at the time such judgment or decree is entered against the
Company, PELLC, any Subsidiary Guarantor or any Significant Subsidiary, remains outstanding
for a period of 60 consecutive days following the entry of such judgment or decree and is
not discharged, waived or the execution thereof stayed; or

     (10) any Subsidiary Guaranty ceases to be in full force and effect (other than in
accordance with the terms of such Subsidiary Guaranty) or any Subsidiary Guarantor denies
or disaffirms its obligations under its Subsidiary Guaranty (other than in accordance with
the terms of such Subsidiary Guaranty).

          The foregoing will constitute Events of Default whatever the reason for any such Event of
Default and whether it is voluntary or involuntary or is effected by

 

 

64

operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body.

          The term “Bankruptcy Law” means Title 11, United States Code, or any similar Federal
or state law for the relief of debtors. The term “Custodian” means any receiver, trustee,
assignee, liquidator, custodian or similar official under any Bankruptcy Law.

          A Default under clauses (4) or (5) is not an Event of Default until the Trustee or the holders
of at least 25% in principal amount of the outstanding Securities notify the Company of the Default
and the Company does not cure such Default within the time specified after receipt of such notice.
Such notice must specify the Default, demand that it be remedied and state that such notice is a
“Notice of Default”.

          The Company shall deliver to the Trustee, within 30 days after the occurrence thereof, written
notice in the form of an Officers’ Certificate of any Event of Default under clause (6) or (10) and
any event which with the giving of notice or the lapse of time would become an Event of Default
under clause (4), (5) or (9), its status and what action the Company is taking or proposes to take
with respect thereto.

          SECTION 6.02. Acceleration. If an Event of Default (other than an Event of Default
specified in Section 6.01(7) or (8) with respect to an Issuer) occurs and is continuing, the
Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the
Securities by notice to the Company and the Trustee, may declare the principal of and accrued but
unpaid interest on all the Securities to be due and payable. Upon such a declaration, such
principal and interest shall be due and payable immediately. If an Event of Default specified in
Section 6.01(7) or (8) with respect to an Issuer occurs, the principal of and interest on all the
Securities shall ipso facto become and be immediately due and payable without any declaration or
other act on the part of the Trustee or any Securityholders. The Holders of a majority in
principal amount of the Securities by notice to the Trustee may rescind an acceleration and its
consequences if the rescission would not conflict with any judgment or decree and if all existing
Events of Default have been cured or waived except nonpayment of principal or interest that has
become due solely because of acceleration. No such rescission shall affect any subsequent Default
or impair any right consequent thereto.

          SECTION 6.03. Other Remedies. If an Event of Default occurs and is continuing, the
Trustee may pursue any available remedy to collect the payment of principal of or interest on the
Securities or to enforce the performance of any provision of the Securities or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any of the Securities or
does not produce any of them in the proceeding. A delay or omission by the Trustee or any
Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair
the right or remedy or constitute a waiver of or
acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All
available remedies are cumulative.

 

 

65

          SECTION 6.04. Waiver of Past Defaults. The Holders of a majority in principal amount
of the Securities by notice to the Trustee may waive an existing Default and its consequences
except (a) a Default in the payment of the principal of or interest on a Security, (b) a Default
arising from the failure to redeem or purchase any Security when required pursuant to this
Indenture or (c) a Default in respect of a provision that under Section 9.02 cannot be amended
without the consent of each Securityholder affected. When a Default is waived, it is deemed cured,
but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

          SECTION 6.05. Control by Majority. The Holders of a majority in principal amount of
the Securities may direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or of exercising any trust or power conferred on the Trustee. However,
the Trustee may refuse to follow any direction that conflicts with law or this Indenture or,
subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of other
Securityholders or would involve the Trustee in personal liability; provided,
however, that the Trustee may take any other action deemed proper by the Trustee that is
not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be
entitled to indemnification satisfactory to it in its sole discretion against all losses and
expenses caused by taking or not taking such action.

          SECTION 6.06. Limitation on Suits. Except to enforce the right to receive payment of
principal, premium (if any) or interest when due, no Securityholder may pursue any remedy with
respect to this Indenture or the Securities unless:

     (1) the Holder gives to the Trustee written notice stating that an Event of Default is
continuing;

     (2) the Holders of at least 25% in principal amount of the Securities make a written
request to the Trustee to pursue the remedy;

     (3) such Holder or Holders offer to the Trustee reasonable security or indemnity
against any loss, liability or expense;

     (4) the Trustee does not comply with the request within 60 days after receipt of the
request and the offer of security or indemnity; and

     (5) the Holders of a majority in principal amount of the Securities do not give the
Trustee a direction inconsistent with the request during such 60-day period.

     A Securityholder may not use this Indenture to prejudice the rights of another Securityholder
or to obtain a preference or priority over another Securityholder. In the event that the
Definitive Securities are not issued to any beneficial owner promptly after the Registrar has
received a request from the Holder of a Global Security to issue
such Definitive Securities to such beneficial owner of its nominee, the Issuers expressly

 

 

66

agree and acknowledge, with respect to the right of any Holder to pursue a remedy pursuant to this
Indenture, the right of such beneficial holder of Securities to pursue such remedy with respect to
the portion of the Global Security that represents such beneficial holder’s Securities as if such
Definitive Securities had been issued.

          SECTION 6.07. Rights of Holders to Receive Payment. Notwithstanding any other
provision of this Indenture, the right of any Holder to receive payment of principal of and
interest on the Securities held by such Holder, on or after the respective due dates expressed in
the Securities, or to bring suit for the enforcement of any such payment on or after such
respective dates, shall not be impaired or affected without the consent of such Holder.

          SECTION 6.08. Collection Suit by Trustee. If an Event of Default specified in Section
6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as
trustee of an express trust against the Issuers for the whole amount then due and owing (together
with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section
7.07.

          SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of
claim and other papers or documents as may be necessary or advisable in order to have the claims of
the Trustee and the Securityholders allowed in any judicial proceedings relative to the Issuers,
their creditors or their property and, unless prohibited by law or applicable regulations, may vote
on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing
similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each
Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its
counsel, and any other amounts due the Trustee under Section 7.07.

          SECTION 6.10. Priorities. If the Trustee collects any money or property pursuant to
this Article 6, it shall pay out the money or property in the following order:

     FIRST: to the Trustee for amounts due under Section 7.07;

     SECOND: to Securityholders for amounts due and unpaid on the Securities for principal
and interest, ratably, without preference or priority of any kind, according to the amounts
due and payable on the Securities for principal and interest, respectively; and

     THIRD: to the Issuers as provided in a written direction from the Company.

          The Trustee may fix a record date and payment date for any payment to Securityholders pursuant
to this Section. At least 15 days before such record date, the Company shall mail to each
Securityholder and the Trustee a notice that states the record date, the payment date and amount to
be paid.

 

 

67

          SECTION 6.11. Undertaking for Costs. In any suit for the enforcement of any right or
remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by
it as Trustee, a court in its discretion may require the filing by any party litigant in the suit
of an undertaking to pay the costs of the suit, and the court in its discretion may assess
reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit,
having due regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder pursuant to
Section 6.07 or a suit by Holders of more than 10% in aggregate principal amount of the Securities.

          SECTION 6.12. Waiver of Stay or Extension Laws. The Issuers (to the extent they may
lawfully do so) shall not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time
hereafter in force, which may affect the covenants or the performance of this Indenture; and the
Issuers (to the extent that they may lawfully do so) hereby expressly waive all benefit or
advantage of any such law, and shall not hinder, delay or impede the execution of any power herein
granted to the Trustee, but shall suffer and permit the execution of every such power as though no
such law had been enacted.

ARTICLE 7

Trustee

          SECTION 7.01. Duties of Trustee.  (a) If an Event of Default has occurred and is
continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use
the same degree of care in their exercise as a prudent Person would exercise or use under the
circumstances in the conduct of such Person’s own affairs.

          (b) Except during the continuance of an Event of Default:

     (1) the Trustee undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture and no implied covenants or obligations shall be
read into this Indenture against the Trustee; and

     (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed therein, upon
certificates or opinions furnished to the Trustee and conforming to the requirements of
this Indenture. However, the Trustee shall examine the certificates and opinions to
determine whether or not they conform to the requirements of this Indenture.

          (c) The Trustee may not be relieved from liability for its own negligent action, its own
negligent failure to act or its own wilful misconduct, except that:

 

 

68

     (1) this paragraph does not limit the effect of paragraph (b) of this Section;

     (2) the Trustee shall not be liable for any error of judgment made in good faith by a
Trust Officer unless it is proved that the Trustee was negligent in ascertaining the
pertinent facts; and

     (3) the Trustee shall not be liable with respect to any action it takes or omits to
take in good faith in accordance with a direction received by it pursuant to Section 6.05.

     (4) No provision of this Indenture shall require the Trustee to expend or risk its own
funds or otherwise incur financial liability in the performance of any of its duties
hereunder or in the exercise of any of its rights or powers, if it shall have reasonable
grounds to believe that repayment of such funds or adequate indemnity against such risk or
liability is not reasonably assured to it.

          (d) Every provision of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b) and (c) of this Section.

          (e) The Trustee shall not be liable for interest on any money received by it except as the
Trustee may agree in writing with the Company.

          (f) Money held in trust by the Trustee need not be segregated from other funds except to the
extent required by law.

          (g) Every provision of this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this Section and to the
provisions of the TIA.

          SECTION 7.02. Rights of Trustee. (a) The Trustee may rely on any document believed
by it to be genuine and to have been signed or presented by the proper person. The Trustee need
not investigate any fact or matter stated in the document.

          (b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate
or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take
in good faith in reliance on the Officers’ Certificate or Opinion of Counsel.

          (c) The Trustee may act through agents and shall not be responsible for the misconduct or
negligence of any agent appointed with due care.

          (d) The Trustee shall not be liable for any action it takes or omits to take in good faith
which it believes to be authorized or within its rights or powers.

          (e) The Trustee may consult with counsel, and the advice or opinion of counsel with respect to
legal matters relating to this Indenture and the Securities shall be full and complete
authorization and protection from liability in respect to any action

 

 

69

taken, omitted or suffered by
it hereunder in good faith and in accordance with the advice or opinion of such counsel.

          (f) The Trustee shall not be deemed to have notice of any Default or Event of Default, except
a Default under Sections 6.01(i) or 6.01(ii), unless written notice of any event which is in fact
such a Default or Event of Default is received by a Trust Officer at its office described in
Section 11.02 herein from either of the Issuers or the Holders of 25% in aggregate principal amount
of the outstanding Securities, and such notice references the specific Default or Event of Default,
the Securities and this Indenture and, in the absence of any such notice, the Trustee may
conclusively assume that no such Default or Event of Default exists.

          SECTION 7.03. Individual Rights of Trustee. The Trustee in its individual or any
other capacity may become the owner or pledgee of Securities and may otherwise deal with the
Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying
Agent, Registrar, co-registrar or co-paying agent may do the same with like rights. However, the
Trustee must comply with Sections 7.10 and 7.11.

          SECTION 7.04. Trustee’s Disclaimer. The Trustee shall not be responsible for and
makes no representation as to the validity or adequacy of this Indenture or the Securities, it
shall not be accountable for the Issuers’ use of the proceeds from the Securities, and it shall not
be responsible for any statement of the Issuers in this Indenture or in any document issued in
connection with the sale of the Securities or in the Securities other than the Trustee’s
certificate of authentication.

          SECTION 7.05. Notice of Defaults. If a Default occurs, is continuing and is known to
the Trustee, the Trustee shall mail to each Securityholder notice of the Default within 90 days
after it occurs. Notwithstanding the immediately preceding sentence, except in the case of a
Default in the payment of principal of or interest on any Security (including payments pursuant to
the mandatory redemption provisions of such Security, if any), the Trustee may withhold the notice
if and so long as a committee of its Trust Officers in good faith determines that withholding the
notice is not opposed to the interests of the Securityholders.

          SECTION 7.06. Reports by Trustee to Holders. As promptly as practicable after each
May 15 beginning with May 15, 2006, and in any event prior to July 15 in each year, the Trustee
shall mail to each Securityholder a brief report dated as of July 15 that complies with TIA §
313(a). During the same time period specified above, the Trustee also shall comply with TIA §
313(b), which section relates to the release or substitution of certain property from the lien of
this Indenture and advances made by the Trustee.

          A copy of each report at the time of its mailing to Securityholders shall be filed with the
SEC and each stock exchange (if any) on which the Securities are listed. The Company agrees to
notify promptly the Trustee whenever the Securities become listed on any stock exchange and of any
delisting thereof.

 

 

70

          SECTION 7.07. Compensation and Indemnity. The Issuers shall pay to the Trustee from
time to time reasonable compensation for its services. The Trustee’s
compensation shall not be limited by any law on compensation of a trustee of an express trust.
The Issuers shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses
incurred or made by it, including costs of collection, in addition to the compensation for its
services. Such expenses shall include the reasonable compensation and expenses, disbursements and
advances of the Trustee’s agents, counsel, accountants and experts. The Issuers shall indemnify
the Trustee against any and all loss, liability or expense (including attorneys’ fees) incurred by
it in connection with the administration of this trust and the performance of its duties hereunder.
The Trustee shall notify the Issuers promptly of any claim for which it may seek indemnity.
Failure by the Trustee to so notify the Issuers shall not relieve the Issuers of their obligations
hereunder. The Issuers shall defend the claim and the Trustee may have separate counsel and the
Issuers shall pay the fees and expenses of such counsel. The Issuers need not reimburse any
expense or indemnify against any loss, liability or expense incurred by the Trustee through the
Trustee’s own wilful misconduct, negligence or bad faith.

          To secure the Issuers’ payment obligations in this Section, the Trustee shall have a lien
prior to the Securities on all money or property held or collected by the Trustee other than money
or property held in trust to pay principal of and interest on particular Securities.

          The Issuers’ payment obligations pursuant to this Section shall survive the discharge of this
Indenture. When the Trustee incurs expenses after the occurrence of a Default specified in Section
6.01(7) or (8) with respect to an Issuer, the expenses are intended to constitute expenses of
administration under the Bankruptcy Law.

          SECTION 7.08. Replacement of Trustee. The Trustee may resign at any time by so
notifying the Company. The Holders of a majority in principal amount of the Securities may remove
the Trustee by so notifying the Trustee and may appoint a successor Trustee. The Company shall
remove the Trustee if:

     (1) the Trustee fails to comply with Section 7.10;

     (2) the Trustee is adjudged bankrupt or insolvent;

     (3) a receiver or other public officer takes charge of the Trustee or its property; or

     (4) the Trustee otherwise becomes incapable of acting.

          If the Trustee resigns, is removed by the Company or by the Holders of a majority in principal
amount of the Securities and such Holders do not reasonably promptly appoint a successor Trustee,
or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being
referred to herein as the retiring Trustee), the Company shall promptly appoint a successor
Trustee.

 

 

71

          A successor Trustee shall deliver a written acceptance of its appointment to the retiring
Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall
become effective, and the successor Trustee shall have all the rights,
powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a
notice of its succession to Securityholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien provided for in
Section 7.07.

          If a successor Trustee does not take office within 60 days after the retiring Trustee resigns
or is removed, the retiring Trustee or the Holders of 10% in principal amount of the Securities may
petition any court of competent jurisdiction for the appointment of a successor Trustee.

          If the Trustee fails to comply with Section 7.10, any Securityholder may petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

          Notwithstanding the replacement of the Trustee pursuant to this Section, the Issuers’
obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

          SECTION 7.09. Successor Trustee by Merger. If the Trustee consolidates with, merges
or converts into, or transfers all or substantially all its corporate trust business or assets to,
another corporation or banking association, the resulting, surviving or transferee corporation
without any further act shall be the successor Trustee.

          In case at the time such successor or successors by merger, conversion or consolidation to the
Trustee shall succeed to the trusts created by this Indenture any of the Securities shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Securities so authenticated; and in
case at that time any of the Securities shall not have been authenticated, any successor to the
Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the
name of the successor to the Trustee; and in all such cases such certificates shall have the full
force which it is anywhere in the Securities or in this Indenture provided that the certificate of
the Trustee shall have.

          SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all times satisfy
the requirements of TIA § 310(a). The Trustee shall have a combined capital and surplus of at
least $50,000,000 as set forth in its most recent published annual report of condition. The
Trustee shall comply with TIA § 310(b); provided, however, that there shall be
excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other
securities or certificates of interest or participation in other securities of the Issuers are
outstanding if the requirements for such exclusion set forth in TIA § 310(b)(1) are met.

 

 

72

          SECTION 7.11. Preferential Collection of Claims Against Company. The Trustee shall
comply with TIA § 311(a), excluding any creditor relationship listed in
TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to
the extent indicated.

ARTICLE 8

Discharge of Indenture; Defeasance

          SECTION 8.01. Discharge of Liability on Securities; Defeasance.
(a) When (1) the Company delivers to the Trustee all outstanding Securities (other than
Securities replaced pursuant to Section 2.07) for cancellation or (2) all outstanding Securities
have become due and payable, whether at maturity or on a redemption date as a result of the mailing
of a notice of redemption pursuant to Article 3 hereof and the Issuers irrevocably deposit with the
Trustee funds sufficient to pay at maturity or upon redemption all outstanding Securities,
including interest thereon to maturity or such redemption date (other than Securities replaced
pursuant to Section 2.07), and if in either case the Issuers pay all other sums payable hereunder
by the Issuers, then this Indenture shall, subject to Section 8.01(c), cease to be of further
effect. The Trustee shall acknowledge satisfaction and discharge of this Indenture on demand of
the Company accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and
expense of the Company.

          (b) Subject to Sections 8.01(c) and 8.02, the Issuers at any time may terminate (1) all their
obligations under the Securities and this Indenture (“legal defeasance option”) or (2) their
obligations under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12 or 4.13
and the operation of Sections 6.01(4), 6.01(6), 6.01(7), 6.01(8), 6.01(9) and 6.01(10) (but, in the
case of Sections 6.01(7) and (8), with respect only to Significant Subsidiaries and Subsidiary
Guarantors) and the limitations contained in Section 5.01(a)(3) (“covenant defeasance option”).
The Issuers may exercise their legal defeasance option notwithstanding its prior exercise of its
covenant defeasance option.

          If the Issuers exercise their legal defeasance option, payment of the Securities may not be
accelerated because of an Event of Default with respect thereto. If the Issuers exercise their
covenant defeasance option, payment of the Securities may not be accelerated because of an Event of
Default specified in Sections 6.01(4), 6.01(6), 6.01(7), 6.01(8), 6.01(9) and 6.01(10) (but, in the
case of Sections 6.01(7) and (8), with respect only to Significant Subsidiaries and Subsidiary
Guarantors) or because of the failure of the Company to comply with Section 5.01(a)(3). If the
Issuers exercise their legal defeasance option or their covenant defeasance option, each Subsidiary
Guarantor, if any, shall be released from all its obligations with respect to its Subsidiary
Guaranty.

 

 

73

          Upon satisfaction of the conditions set forth herein and upon request of the Company, the
Trustee shall acknowledge in writing the discharge of those obligations that the Company
terminates.

          (c) Notwithstanding clauses (a) and (b) above, the Issuers’ obligations in Sections 2.03,
2.04, 2.05, 2.06, 2.07, 2.08, 7.07 and 7.08 and in this Article 8 shall survive until the
Securities have been paid in full. Thereafter, the Issuers’ obligations in Sections 7.07, 8.04 and
8.05 shall survive.

          SECTION 8.02. Conditions to Defeasance. The Issuers may exercise their legal
defeasance option or their covenant defeasance option only if:

      (1) the Issuers irrevocably deposit in trust with the Trustee money or U.S. Government
Obligations for the payment of principal of and interest on the Securities to maturity or
redemption, as the case may be;

      (2) the Company delivers to the Trustee a certificate from a nationally recognized
firm of independent accountants expressing their opinion that the payments of principal and
interest when due and without reinvestment on the deposited U.S. Government Obligations
plus any deposited money without investment will provide cash at such times and in such
amounts as will be sufficient to pay principal and interest when due on all the Securities
to maturity or redemption, as the case may be;

      (3) 123 days pass after the deposit is made and during the 123-day period no Default
specified in Sections 6.01(7) or (8) with respect to the Issuers occurs which is continuing
at the end of the period;

      (4) the deposit does not constitute a default under any other agreement binding on the
Issuers;

      (5) the Company delivers to the Trustee an Opinion of Counsel to the effect that the
trust resulting from the deposit does not constitute, or is qualified as, a regulated
investment company under the Investment Company Act of 1940;

      (6) in the case of the legal defeasance option, the Company shall have delivered to
the Trustee an Opinion of Counsel stating that since the date of this Indenture (A) the
Company has received from, or there has been published by, the Internal Revenue Service a
ruling, or (B) there has been a change in the applicable Federal income tax law, in either
case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the
Securityholders will not recognize income, gain or loss for Federal income tax purposes as
a result of such deposit and defeasance and will be subject to Federal income tax on the
same amounts, in the same manner and at the same times as would have been the case if such
defeasance had not occurred;

 

 

74

          (7) in the case of the covenant defeasance option, the Company shall have delivered to
the Trustee an Opinion of Counsel to the effect that the Securityholders will not recognize
income, gain or loss for Federal income tax purposes as a result of such deposit and
defeasance and will be subject to Federal income tax on the same amounts, in the same
manner and at the same times as would have been the case if such covenant defeasance had
not occurred; and

          (8) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that all conditions precedent to the defeasance and discharge of the
Securities as contemplated by this Article 8 have been complied with.

          Before or after a deposit, the Issuers may make arrangements satisfactory to the Trustee for
the redemption of Securities at a future date in accordance with Article 3.

          SECTION 8.03. Application of Trust Money. The Trustee shall hold in trust money or
U.S. Government Obligations deposited with it pursuant to this Article 8. It shall apply the
deposited money and the money from U.S. Government Obligations through the Paying Agent and in
accordance with this Indenture to the payment of principal of and interest on the Securities.

          SECTION 8.04. Repayment to Issuers. The Trustee and the Paying Agent shall promptly
turn over to the Issuers upon request any excess money or securities held by them at any time.

          Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay
to the Issuers upon request any money held by them for the payment of principal or interest that
remains unclaimed for two years, and, thereafter, Securityholders entitled to the money must look
to the Issuers for payment as general creditors.

          SECTION 8.05. Indemnity for Government Obligations. The Issuers shall pay and shall
indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited
U.S. Government Obligations or the principal and interest received on such U.S. Government
Obligations.

          SECTION 8.06. Reinstatement. If the Trustee or Paying Agent is unable to apply any
money or U.S. Government Obligations in accordance with this Article 8 by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, each Issuer’s and each Subsidiary
Guarantor’s obligations under this Indenture, and the Securities shall be revived and reinstated as
though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or Paying
Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this
Article 8; provided, however, that, if the Issuers have made any payment of
interest on or principal of any Securities because of the reinstatement of its obligations, the
Issuers shall be subrogated

 

 

75

to the rights of the Holders of such Securities to receive such payment
from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

ARTICLE 9

Amendments

          SECTION 9.01. Without Consent of Holders. The Issuers, the Subsidiary Guarantors and
the Trustee may amend this Indenture or the Securities without notice to or consent of any
Securityholder:

          (1) to cure any ambiguity, omission, defect or inconsistency;

          (2) to comply with Article 5;

          (3) to provide for uncertificated Securities in addition to or in place of
certificated Securities; provided, however, that the uncertificated
Securities are issued in registered form for purposes of Section 163(f) of the Code or in a
manner such that the uncertificated Securities are described in Section 163(f)(2)(B) of the
Code;

          (4) to add Guarantees with respect to the Securities, including any Subsidiary
Guaranties, or to secure the Securities;

          (5) to add to the covenants of the Company, PELLC or any Subsidiary Guarantor for the
benefit of the Holders or to surrender any right or power herein conferred upon the
Company, PELLC or any Subsidiary Guarantor;

          (6) to comply with any requirements of the SEC in connection with qualifying, or
maintaining the qualification of, this Indenture under the TIA;

          (7) to make any change that does not adversely affect the rights of any Securityholder
and any change to conform this Indenture to any terms explicitly described in the
“Description of the Notes” section of the Offering Circular; or

          (8) to make any amendment to the provisions of this Indenture relating to the transfer
and legending of Securities; provided, however, that (a) compliance with
this Indenture as so amended would not result in Securities being transferred in violation
of the Securities Act or any other applicable securities law and (b) such amendment does
not materially and adversely affect the rights of Holders to transfer Securities.

          After an amendment under this Section becomes effective, the Company shall mail to
Securityholders a notice briefly describing such amendment. The failure to

 

 

76

give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an amendment
under this Section.

          SECTION 9.02. With Consent of Holders. The Issuers, the Subsidiary Guarantors and the
Trustee may amend this Indenture or the Securities with the written consent of the Holders of at
least a majority in principal amount of the Securities then outstanding (including consents
obtained in connection with a tender offer or exchange
for the Securities) and any past default or compliance with any provisions may also be waived
with the consent of the Holders of at least a majority in principal amount of the Securities then
outstanding. However, without the consent of each Securityholder affected thereby, an amendment or
waiver may not:

          (1) reduce the amount of Securities whose Holders must consent to an amendment;

          (2) reduce the rate of or extend the time for payment of interest on any Security;

          (3) reduce the principal of or change the Stated Maturity of any Security;

          (4) change the provisions applicable to the redemption of any Security contained in
Article 3 hereto or paragraph 5 of the Securities;

          (5) make any Security payable in money other than that stated in the Security;

          (6) make any changes in the ranking or priority of any Security that would adversely
affect the Securityholders;

          (7) make any change in Section 6.04 or 6.07 or the second sentence of this Section; or

          (8) make any change in, or release other than in accordance with this Indenture, any
Subsidiary Guaranty that would adversely affect the Securityholders.

          It shall not be necessary for the consent of the Holders under this Section to approve the
particular form of any proposed amendment, but it shall be sufficient if such consent approves the
substance thereof.

          After an amendment under this Section becomes effective, the Company shall mail to
Securityholders a notice briefly describing such amendment. The failure to give such notice to all
Securityholders, or any defect therein, shall not impair or affect the validity of an amendment
under this Section.

 

 

77

          SECTION 9.03. Compliance with Trust Indenture Act. Every amendment to this Indenture
or the Securities shall comply with the TIA as then in effect.

          SECTION 9.04. Revocation and Effect of Consents and Waivers. A consent to an
amendment or a waiver by a Holder of a Security shall bind the Holder and every subsequent Holder
of that Security or portion of the Security that evidences the same debt as the consenting Holder’s
Security, even if notation of the consent or waiver is not made on the Security. However, any such
Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security or
portion of the Security if the Trustee receives the notice of revocation before the date the
amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every
Securityholder. An amendment or waiver becomes effective upon the execution of such amendment or
waiver by the Trustee.

          The Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Securityholders entitled to give their consent or take any other action described
above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed,
then notwithstanding the immediately preceding paragraph, those Persons who were Securityholders at
such record date (or their duly designated proxies), and only those Persons, shall be entitled to
give such consent or to revoke any consent previously given or to take any such action, whether or
not such Persons continue to be Holders after such record date. No such consent shall be valid or
effective for more than 120 days after such record date.

          SECTION 9.05. Notation on or Exchange of Securities. If an amendment changes the
terms of a Security, the Trustee may require the Holder of the Security to deliver it to the
Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms
and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the
Issuers in exchange for the Security shall issue and the Trustee shall authenticate a new Security
that reflects the changed terms. Failure to make the appropriate notation or to issue a new
Security shall not affect the validity of such amendment.

          SECTION 9.06. Trustee To Sign Amendments. The Trustee shall sign any amendment
authorized pursuant to this Article 9 if the amendment does not adversely affect the rights,
duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign
it. In signing such amendment the Trustee shall be entitled to receive indemnity reasonably
satisfactory to it and to receive, and (subject to Section 7.01) shall be fully protected in
relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment is
authorized or permitted by this Indenture.

          SECTION 9.07. Payment for Consent. Neither the Issuers nor any Affiliate of the
Issuers shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of this Indenture or the Securities unless such
consideration is offered to all Holders and is paid

 

 

78

to all Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or
agreement.

ARTICLE 10

Subsidiary Guaranties

          SECTION 10.01. Guaranties. Each Subsidiary Guarantor hereby unconditionally and
irrevocably guarantees, jointly and severally, to each Holder and to the Trustee and its successors
and assigns (a) the full and punctual payment of principal
of and interest on the Securities when due, whether at maturity, by acceleration, by
redemption or otherwise, and all other monetary obligations of the Issuers under this Indenture and
the Securities and (b) the full and punctual performance within applicable grace periods of all
other obligations of the Issuers under this Indenture and the Securities (all the foregoing being
hereinafter collectively called the “Guaranteed Obligations”). Each Subsidiary Guarantor further
agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without
notice or further assent from such Subsidiary Guarantor and that such Subsidiary Guarantor will
remain bound under this Article 10 notwithstanding any extension or renewal of any Obligation.

          Each Subsidiary Guarantor waives presentation to, demand of, payment from and protest to the
Issuers of any of the Guaranteed Obligations and also waives notice of protest for nonpayment.
Each Subsidiary Guarantor waives notice of any default under the Securities or the Guaranteed
Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be affected by (1)
the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or
remedy against the Issuers or any other Person (including any Subsidiary Guarantor) under this
Indenture, the Securities or any other agreement or otherwise; (2) any extension or renewal of any
thereof; (3) any rescission, waiver, amendment or modification of any of the terms or provisions of
this Indenture, the Securities or any other agreement; (4) the release of any security held by any
Holder or the Trustee for the Guaranteed Obligations or any of them; (5) the failure of any Holder
or the Trustee to exercise any right or remedy against any other guarantor of the Guaranteed
Obligations; or (6) except as set forth in Section 10.06, any change in the ownership of such
Subsidiary Guarantor.

          Each Subsidiary Guarantor further agrees that its Subsidiary Guaranty herein constitutes a
guarantee of payment, performance and compliance when due (and not a guarantee of collection) and
waives any right to require that any resort be had by any Holder or the Trustee to any security
held for payment of the Guaranteed Obligations.

          Except as expressly set forth in Sections 8.01(b), 10.02 and 10.06, the obligations of each
Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or
termination for any reason, including any claim of waiver, release, surrender, alteration or
compromise, and shall not be subject to any defense of

 

 

79

setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the
Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the
obligations of each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise
affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce
any remedy under this Indenture, the Securities or any other agreement, by any waiver or
modification of any thereof, by any default, failure or delay, willful or otherwise, in the
performance of the obligations, or by any other act or thing or omission or delay to do any other
act or thing which may or might in any manner or to any extent vary the risk of such Subsidiary
Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law
or equity.

          Each Subsidiary Guarantor further agrees that its Guarantee herein shall continue to be
effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of
principal of or interest on any Obligation is rescinded or must otherwise be restored by any Holder
or the Trustee upon the bankruptcy or reorganization of an Issuer or otherwise.

          In furtherance of the foregoing and not in limitation of any other right which any Holder or
the Trustee has at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the
failure of the Issuers to pay the principal of or interest on any Obligation when and as the same
shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform
or comply with any other Obligation, each Subsidiary Guarantor hereby promises to and shall, upon
receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the
Holders or the Trustee an amount equal to the sum of (A) the unpaid amount of such Guaranteed
Obligations, (B) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent
not prohibited by law) and (C) all other monetary Guaranteed Obligations of the Issuers to the
Holders and the Trustee.

          Each Subsidiary Guarantor further agrees that, as between it, on the one hand, and the Holders
and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations hereby may be
accelerated as provided in Article 6 for the purposes of such Subsidiary Guarantor’s Subsidiary
Guaranty herein, notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of
any declaration of acceleration of such Guaranteed Obligations as provided in Article 6, such
Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by
such Subsidiary Guarantor for the purposes of this Section.

          Each Subsidiary Guarantor also agrees to pay any and all costs and expenses (including
reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under
this Section.

          SECTION 10.02. Limitation on Liability. Any term or provision of this Indenture to
the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed
hereunder by any Subsidiary Guarantor shall not

 

 

80

exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Subsidiary Guarantor, voidable
under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws
affecting the rights of creditors generally.

          SECTION 10.03. Successors and Assigns. This Article 10 shall be binding upon each
Subsidiary Guarantor and its successors and assigns and shall enure to the benefit of the
successors and assigns of the Trustee and the Holders and, in the event of any transfer or
assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that
party in this Indenture and in the Securities shall automatically extend to and be vested in such
transferee or assignee, all subject to the terms and conditions of this Indenture.

          SECTION 10.04. No Waiver. Neither a failure nor a delay on the part of either the
Trustee or the Holders in exercising any right, power or privilege under this Article 10 shall
operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or
further exercise of any right, power or privilege. The rights, remedies and benefits of the
Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other
rights, remedies or benefits which either may have under this Article 10 at law, in equity, by
statute or otherwise.

          SECTION 10.05. Modification. No modification, amendment or waiver of any provision of
this Article 10, nor the consent to any departure by any Subsidiary Guarantor therefrom, shall in
any event be effective unless the same shall be in writing and signed by the Trustee, and then such
waiver or consent shall be effective only in the specific instance and for the purpose for which
given. No notice to or demand on any Subsidiary Guarantor in any case shall entitle such
Subsidiary Guarantor to any other or further notice or demand in the same, similar or other
circumstances.

          SECTION 10.06. Release of Subsidiary Guarantor. A Subsidiary Guarantor will be
released from its obligations under this Article 10 (other than any obligation that may have arisen
under Section 10.07)

      (1) upon the sale (including any sale pursuant to any exercise of remedies by a holder
of Indebtedness of the Issuers or of such Subsidiary Guarantor) or other disposition
(including by way of consolidation or merger) of a Subsidiary Guarantor,

      (2) upon the sale or disposition of all or substantially all the assets of such
Subsidiary Guarantor,

      (3) upon the designation of such Subsidiary Guarantor as an Unrestricted Subsidiary in
accordance with the terms of this Indenture,

      (4) at such time as such Subsidiary Guarantor does not have any Indebtedness
outstanding that would have required such Subsidiary Guarantor to

 

 

81

enter into a Guaranty Agreement pursuant to Section 4.13 and the Company provides an Officers’ Certificate to the
Trustee certifying that no such Indebtedness is outstanding and that the Company elects to
have such Subsidiary Guarantor released from this Article 10, or

          (5) upon defeasance of the Securities pursuant to Article 8, or

          (6) upon the full satisfaction of the Issuers’ obligations under this Indenture;

provided, however, that in the case of clauses (1) and (2) above, (i) such
sale or other disposition is made to a Person other than the Issuers or an Affiliate of the
Issuers, (ii) such sale or disposition is otherwise permitted by this Indenture and (iii)
the Company provides an Officers’ Certificate to the Trustee to the effect that the Company
will comply with its obligations under Section 4.06.

At the request of the Company, the Trustee shall execute and deliver an appropriate instrument
evidencing such release.

          SECTION 10.07. Contribution. Each Subsidiary Guarantor that makes a payment under its
Subsidiary Guaranty shall be entitled upon payment in full of all Guaranteed Obligations under this
Indenture to a contribution from each other Subsidiary Guarantor in an amount equal to such other
Subsidiary Guarantor’s pro rata portion of such payment based on the respective net assets of all
the Subsidiary Guarantors at the time of such payment determined in accordance with GAAP.

at the Securityholder’s address as it appears on the registration books of the Registrar and shall
be sufficiently given if so mailed within the time prescribed.

          Failure to mail a notice or communication to a Securityholder or any defect in it shall not

mailed in the manner provided above, it is duly given, whether or not the addressee receives it.

          SECTION 11.03. Communication by Holders with Other Holders. Securityholders may

          SECTION 11.06. When Securities Disregarded. In determining whether the Holders of the
required principal amount of Securities have concurred in any direction, waiver or consent,
Securities owned by the Company or by any Person directly or indirectly controlling or controlled
by or under direct or indirect common control with
the Company shall be disregarded and deemed not to be outstanding, except that, for the
purpose of determining whether the Trustee shall be protected in relying on any such direction,
waiver or consent, only Securities which the Trustee knows are so owned shall be so disregarded.
Also, subject to the foregoing, only Securities outstanding at the time shall be considered in any
such determination.

          SECTION 11.07. Rules by Trustee, Paying Agent and Registrar. The Trustee may make
reasonable rules for action by or a meeting of Securityholders. The Registrar and the Paying Agent
may make reasonable rules for their functions.

liability for any obligations of the Issuers under the Securities or this Indenture or of such
Subsidiary Guarantor under its Subsidiary Guaranty or this Indenture or for any claim based on, in
respect of or by reason of such obligations or their creation. By accepting a Security, each
Securityholder shall waive and release all such liability. The waiver and release shall be part of
the consideration for the issue of the Securities.

          SECTION 11.11. Successors. All agreements of the Issuers in this Indenture and the

            2.1 (a) Form and Dating. The Initial Securities will be offered and sold by the
Issuers pursuant to a Purchase Agreement. The Initial Securities will be resold initially only to
(i) QIBs in reliance on Rule 144A under the Securities Act (“Rule 144A”) and (ii) Persons other

Global Security, a permanent global security (the “Permanent Regulation S Global
Security”, and together with the Temporary Regulation S Global Security, the “Regulation S
Global Security”) or any other Security prior to the expiration of the Distribution Compliance
Period and then, after the expiration of the Distribution Compliance Period, may be exchanged for
interests in a Rule 144A Global Security, an IAI Global Security or the Permanent Regulation S
Global Security only upon certification in form reasonably satisfactory to the Trustee that (i)
beneficial ownership interests in such Temporary Regulation S Global Security are owned either by
non-U.S. persons or U.S. persons who purchased such interests in a transaction that did not require
registration under the Securities Act and (ii) in the case of an exchange for an IAI Global
Security, certification that the interest in the Temporary Regulation S Global Security is being
transferred to an institutional “accredited investor” under the Securities Act that is an
institutional accredited investor acquiring the securities for its own account or for the account
of an institutional accredited investor.

          Beneficial interests in Temporary Regulation S Global Securities or IAI Global Securities may
be exchanged for interests in Rule 144A Global Securities if (1) such exchange occurs in connection
with a transfer of Securities in compliance with Rule 144A and (2) the transferor of the beneficial
interest in the Temporary Regulation S Global Security or the IAI Global Security, as applicable,
first delivers to the Trustee a written certificate (in a form satisfactory to the Trustee) to the
effect that the beneficial interest in the Temporary Regulation S Global Security or the IAI Global
Security, as applicable, is being transferred to a Person (a) who the transferor reasonably
believes to be a QIB, (b) purchasing for its own account or the account of a QIB in a transaction
meeting the requirements of Rule 144A, and (c) in accordance with all applicable securities laws of
the States of the United States and other jurisdictions.

          Beneficial interests in Temporary Regulation S Global Securities and Rule 144A Global
Securities may be exchanged for an interest in IAI Global Securities if (1) such exchange occurs in
connection with a transfer of the securities in compliance with an exemption under the Securities
Act and (2) the transferor of the Regulation S Global Security or Rule 144A Global Security, as
applicable, first delivers to the trustee a written certificate (substantially in the form of
Exhibit 2) to the effect that (A) the Regulation S Global Security or Rule 144A Global Security, as
applicable, is being transferred (a) to an “accredited investor” within the meaning of
501(a)(1),(2),(3) and (7) under the Securities Act that is an institutional investor acquiring the
securities for its own account or for the account of such an institutional accredited investor, in
each case in a minimum principal amount of the securities of $250,000, for investment purposes and
not with a view to or for offer or sale in connection with any distribution in violation of the
Securities Act and (B) in accordance with all applicable securities laws of the States of the
United States and other jurisdictions.

          Beneficial interests in a Rule 144A Global Security or an IAI Global Security may be
transferred to a Person who takes delivery in the form of an interest in a Regulation S Global
Security, whether before or after the expiration of the Distribution Compliance Period, only if the
transferor first delivers to the Trustee a written certificate

 

 

5

(in the form provided in the Indenture) to the effect that such transfer is being made in accordance with Rule 903 or 904 of
Regulation S or Rule 144 (if applicable).

          The Rule 144A Global Security, the IAI Global Security, the Temporary Regulation S Global
Security and the Permanent Regulation S Global Security are collectively referred to herein as
“Global Securities”. The aggregate principal amount of the Global Securities may from time to time
be increased or decreased by adjustments made on the records of the Trustee and the Depository or
its nominee as hereinafter provided.

          (b) Book-Entry Provisions. This Section 2.1(b) shall apply only to a Global Security
deposited with or on behalf of the Depository.

          The Issuers shall execute and the Trustee shall, in accordance with this Section 2.1(b),
authenticate and deliver initially one or more Global Securities that (a) shall be registered in
the name of the Depository for such Global Security or Global Securities or the nominee of such
Depository and (b) shall be delivered by the Trustee to such Depository or pursuant to such
Depository’s instructions or held by the Trustee as custodian for the Depository.

          Members of, or participants in, the Depository (“Agent Members”) shall have no rights under
this Indenture with respect to any Global Security held on their behalf by the Depository or by the
Trustee as the custodian of the Depository or under such Global Security, and the Issuers, the
Trustee and any agent of the Issuers or the Trustee shall be entitled to treat the Depository as
the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the
foregoing, nothing herein shall prevent the Issuers, the Trustee or any agent of the Issuers or the
Trustee from giving effect to any written certification, proxy or other authorization furnished by
the Depository or impair, as between the Depository and its Agent Members, the operation of
customary practices of such Depository governing the exercise of the rights of a holder of a
beneficial interest in any Global Security.

          (c) Definitive Securities. Except as provided in this Section 2.1 or Section 2.3 or
2.4, owners of beneficial interests in Global Securities shall not be entitled to receive physical
delivery of Definitive Securities.

          2.2 Authentication. The Trustee shall authenticate and deliver: (1) on the Issue
Date, an aggregate principal amount of $125 million of 10-3/8% Senior Notes Due 2012, (2) any
Additional Securities for an original issue in an aggregate principal amount specified in the
written order of the Issuers pursuant to Section 2.02 of the Indenture and (3) Exchange Securities
or Private Exchange Securities for issue only in a Registered Exchange Offer or a Private Exchange,
respectively, pursuant to a Registration Rights Agreement, for a like principal amount of Initial
Securities, in each case upon a written order of the Issuers signed by two Officers or by an

order shall specify the amount of the Securities to be authenticated and the date on which the
original issue of Securities is to be authenticated and, in the case of any issuance of

 

 

6

Additional Securities pursuant to Section 2.13 of the Indenture, shall certify that such issuance is in
compliance with Section 4.03 of the Indenture.

	 	2.3  	Transfer and Exchange.

          (a) Transfer and Exchange of Definitive Securities. When Definitive Securities are
presented to the Registrar with a request:

	 	(x)  	to register the transfer of such Definitive Securities; or
	 
	 	(y)  	to exchange such Definitive Securities for an equal principal
amount of Definitive Securities of other authorized denominations,

the Registrar shall register the transfer or make the exchange as requested if its reasonable
requirements for such transaction are met; provided, however, that the Definitive
Securities surrendered for transfer or exchange:

          (i) shall be duly endorsed or accompanied by a written instrument of transfer in form
reasonably satisfactory to the Company and the Registrar, duly executed by the Holder
thereof or its attorney duly authorized in writing; and

          (ii) if such Definitive Securities are required to bear a restricted securities
legend, they are being transferred or exchanged pursuant to an effective registration
statement under the Securities Act, pursuant to Section 2.3(b) or pursuant to clause (A),
(B) or (C) below, and are accompanied by the following additional information and
documents, as applicable:

          (A) if such Definitive Securities are being delivered to the Registrar by a
Holder for registration in the name of such Holder, without transfer, a
certification from such Holder to that effect; or

          (B) if such Definitive Securities are being transferred to the Company, a
certification to that effect; or

          (C) if such Definitive Securities are being transferred (x) pursuant to an
exemption from registration in accordance with Rule 144A, Regulation S or Rule 144
under the Securities Act; or (y) in reliance upon another exemption from the
requirements of the Securities Act: (i) a certification to that effect (in the
form set forth on the reverse of the Security) and (ii) if the Company so requests,
an opinion of counsel or other evidence reasonably satisfactory to it as to the
compliance with the restrictions set forth in the legend set forth in Section
2.3(e)(i).

          (b) Restrictions on Transfer of a Definitive Security for a Beneficial Interest in a
Global Security. A Definitive Security may not be exchanged for a beneficial interest in a
Rule 144A Global Security, an IAI Global Security or a Permanent Regulation S Global Security
except upon satisfaction of the requirements set forth

 

 

7

below. Upon receipt by the Trustee of a Definitive Security, duly endorsed or accompanied by appropriate instruments of transfer, in form
satisfactory to the Trustee, together with:

          (i) certification, in the form set forth on the reverse of the Security, that
such Definitive Security is either (A) being transferred to a QIB in accordance
with Rule 144A, (B) being transferred to an IAI or (C) being transferred after
expiration of the Distribution Compliance Period by a Person who initially
purchased such Security in reliance on Regulation S to a buyer who elects to hold
its interest in such Security in the form of a beneficial interest in the Permanent
Regulation S Global Security; and

          (ii) written instructions directing the Trustee to make, or to direct the
Securities Custodian to make, an adjustment on its books and records with respect
to such Rule 144A Global Security (in the case of a transfer pursuant to clause
(b)(i)(A)), IAI Global Security (in the case of a transfer pursuant to clause
(b)(1)(B)) or Permanent Regulation S Global Security (in the case of a transfer
pursuant to clause (b)(i)(B)) to reflect an increase in the aggregate principal
amount of the Securities represented by the Rule 144A Global Security, IAI Global
Security or Permanent Regulation S Global Security, as applicable, such
instructions to contain information regarding the Depository account to be credited
with such increase,

then the Trustee shall cancel such Definitive Security and cause, or direct the Securities
Custodian to cause, in accordance with the standing instructions and procedures existing between
the Depository and the Securities Custodian, the aggregate principal amount of Securities
represented by the Rule 144A Global Security, IAI Global Security or Permanent Regulation S Global
Security, as applicable, to be increased by the aggregate principal amount of the Definitive
Security to be exchanged and shall credit or cause to be credited to the account of the Person
specified in such instructions a beneficial interest in the Rule 144A Global Security, IAI Global
Security or Permanent Regulation S Global Security, as applicable, equal to the principal amount of
the Definitive Security so canceled. If no Rule 144A Global Securities, IAI Global Securities or
Permanent Regulation S Global Securities, as applicable, are then outstanding, the Issuers shall
issue and the Trustee shall authenticate, upon written order of the Issuers in the form of an
Officers’ Certificate of the Issuers, a new Rule 144A Global Security, IAI Global Security or
Permanent Regulation S Global Security, as applicable, in the appropriate principal amount.

(c) Transfer and Exchange of Global Securities.

          (i) The transfer and exchange of Global Securities or beneficial interests
therein shall be effected through the Depository, in accordance with this Indenture
(including applicable restrictions on transfer set forth herein, if any) and the
procedures of the Depository

 

 

8

therefor. A transferor of a beneficial interest in a
Global Security shall deliver to the Registrar a written order given in accordance
with the Depository’s procedures containing information regarding the participant
account of the Depository to be credited with a beneficial interest in the
Global Security. The Registrar shall, in accordance with such instructions
instruct the Depository to credit to the account of the Person specified in such
instructions a beneficial interest in the Global Security and to debit the account
of the Person making the transfer the beneficial interest in the Global Security
being transferred.

          (ii) If the proposed transfer is a transfer of a beneficial interest in one
Global Security to a beneficial interest in another Global Security, the Registrar
shall reflect on its books and records the date and an increase in the principal
amount of the Global Security to which such interest is being transferred in an
amount equal to the principal amount of the interest to be so transferred, and the
Registrar shall reflect on its books and records the date and a corresponding
decrease in the principal amount of the Global Security from which such interest is
being transferred.

          (iii) Notwithstanding any other provisions of this Appendix (other than the
provisions set forth in Section 2.4), a Global Security may not be transferred as a
whole except by the Depository to a nominee of the Depository or by a nominee of
the Depository to the Depository or another nominee of the Depository or by the
Depository or any such nominee to a successor Depository or a nominee of such
successor Depository.

          (iv) In the event that Global Security is exchanged for Definitive Securities
to Section 2.4 of this Appendix, prior to the consummation of a Registered Exchange
Offer or the effectiveness of a Shelf Registration Statement with respect to such
Securities, such Securities may be exchanged only in accordance with such
procedures as are substantially consistent with the provisions of this Section 2.3
(including the certification requirements set forth on the reverse of the Initial
Securities intended to ensure that such transfers comply with Rule 144A, Regulation
S or another applicable exemption under the Securities Act, as the case may be) and
such other procedures as may from time to time be adopted by the Company.

case of Securities offered otherwise than in reliance on Regulation S shall bear a
legend in substantially the following form:

THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION
EXEMPT FROM REGISTRATION UNDER THE UNITED STATES SECURITIES ACT OF 1933,
AS AMENDED (THE “SECURITIES ACT”), AND THIS SECURITY MAY NOT BE OFFERED,
SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN
APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THIS SECURITY IS HEREBY
NOTIFIED THAT THE SELLER OF THIS SECURITY MAY BE RELYING ON THE EXEMPTION
FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE
144A THEREUNDER.

THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE ISSUERS THAT (A)
THIS SECURITY MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED,
ONLY (I) TO THE ISSUERS, (II) IN THE UNITED STATES TO A PERSON WHOM THE
SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED
IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE
REQUIREMENTS OF RULE 144A, (III) TO AN “ACCREDITED INVESTOR” WITHIN THE
MEANING OF RULE 501(A)(1),(2),(3) OR (7) UNDER THE SECURITIES ACT THAT,

RESTRICTIONS REFERRED TO IN (A) ABOVE.

         Each certificate evidencing a Security offered in reliance on Regulation S
shall, in addition to the foregoing, bear a legend in substantially the following
form:

THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION
ORIGINALLY EXEMPT FROM REGISTRATION UNDER THE U.S. SECURITIES ACT OF 1933,
AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE TRANSFERRED IN THE
UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY U.S. PERSON
EXCEPT PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT AND ALL APPLICABLE STATE SECURITIES
LAWS. TERMS USED ABOVE HAVE THE MEANINGS GIVEN TO THEM IN REGULATION S
UNDER THE SECURITIES ACT.

         Each Definitive Security shall also bear the following additional legend:

IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE REGISTRAR
AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS SUCH
TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER
COMPLIES WITH THE FOREGOING RESTRICTIONS.

         (ii) Upon any sale or transfer of a Transfer Restricted Security (including
any Transfer Restricted Security represented by a Global Security) pursuant to Rule
144 under the Securities Act, the Registrar shall permit the transferee thereof to
exchange such Transfer Restricted Security for a certificated Security that does
not bear the legend set forth above and rescind any restriction on the transfer of
such Transfer Restricted Security, if the transferor thereof certifies in writing
to the Registrar that such sale or transfer was made in reliance on Rule 144 (such
certification to be in the form set forth on the reverse of the Security).

 

 

11

         (iii) After a transfer of any Initial Securities or Private Exchange
Securities pursuant to and during the period of the effectiveness of a Shelf
Registration Statement with respect to such Initial Securities or Private Exchange
Securities, as the case may be, all requirements pertaining to legends on such
Initial Security or such Private Exchange
Security will cease to apply, the requirements requiring any such Initial
Security or such Private Exchange Security issued to certain Holders be issued in
global form will cease to apply, and a certificated Initial Security or Private
Exchange Security or an Initial Security or Private Exchange Security in global

transferee of the Holder of such Initial Securities or Private Exchange Securities
upon exchange of such transferring Holder’s certificated Initial Security or
Private Exchange Security or directions to transfer such Holder’s interest in the
Global Security, as applicable.

         (iv) Upon the consummation of a Registered Exchange Offer with respect to the
Initial Securities, all requirements pertaining to such Initial Securities that
Initial Securities issued to certain Holders be issued in global form will still
apply with respect to Holders of such Initial Securities that do not exchange their
Initial Securities, and Exchange Securities in certificated or global form, in each
case without the restricted securities legend set forth in Exhibit 1 hereto will be
available to Holders that exchange such Initial Securities in such Registered
Exchange Offer.

         (v) Upon the consummation of a Private Exchange with respect to the Initial
Securities, all requirements pertaining to such Initial Securities that Initial

securities legend and the applicable restricted securities legend set forth in
Exhibit 1 hereto will be available to Holders that exchange such Initial Securities
in such Private Exchange.

          (f) Cancellation or Adjustment of Global Security. At such time as all beneficial
interests in a Global Security have either been exchanged for Definitive Securities, redeemed,
purchased or canceled, such Global Security shall be returned to the Depository for cancellation or
retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial
interest in a Global Security is exchanged for certificated Securities, redeemed, purchased or
canceled, the principal amount of Securities represented by such Global Security shall be reduced
and an adjustment shall be made on the books and records of the Trustee (if it is then the
Securities Custodian for such Global Security) with respect to such Global Security, by the Trustee
or the Securities Custodian, to reflect such reduction.

owner of a Global Security, a member of, or a participant in the Depository or
other Person with respect to the accuracy of the records of the Depository or its
nominee or of any participant or member thereof, with respect to any ownership
interest in the Securities or with respect to
the delivery to any participant, member, beneficial owner or other Person
(other than the Depository) of any notice (including any notice of redemption) or
the payment of any amount, under or with respect to such Securities. All notices
and communications to be given to the Holders and all payments to be made to
Holders under the Securities shall be given or made only to or upon the order of
the registered Holders (which shall be the Depository or its nominee in the case of
a Global Security). The rights of beneficial owners in any Global Security shall
be exercised only through the Depository subject to the applicable rules and
procedures of the Depository. The Trustee may rely and shall be fully protected in
relying upon information furnished by the Depository with respect to its members,
participants and any beneficial owners.

of such certificates and other documentation or evidence as are expressly required
by, and to do so if and when expressly required by, the terms of this Indenture,
and to examine the same to determine substantial compliance as to form with the
express requirements hereof.

	 	2.4  	Definitive Securities.

          (a) A Global Security deposited with the Depository or with the Trustee as Securities
Custodian for the Depository pursuant to Section 2.1 shall be transferred to the beneficial owners
thereof in the form of Definitive Securities in an aggregate principal amount equal to the
principal amount of such Global Security, in exchange for such Global Security, only if such
transfer complies with Section 2.3 hereof and (i) the Depository notifies the Issuers that it is
unwilling or unable to continue as Depository for such Global Security and the Depository fails to
appoint a successor depository or if at any time such Depository ceases to be a “clearing agency”
registered under the Exchange Act, in either case, and a successor depository is not appointed by
the Company within 90 days of such notice, or (ii) an Event of Default has occurred and is
continuing or (iii) the Company, in its sole discretion, notifies the Trustee in writing that it
elects to cause the issuance of Definitive Securities under this Indenture.

          (b) Any Global Security that is transferable to the beneficial owners thereof pursuant to this

13

located at its principal corporate trust office in the Borough of Manhattan, The City of New York, to be so transferred, in
whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver,

(d) In the event of the occurrence of one of the events specified in Section 2.4(a) hereof,
the Issuers shall promptly make available to the Trustee a reasonable supply of Definitive
Securities in definitive, fully registered form without interest coupons. In the event that such
Definitive Securities are not issued, the Issuers expressly acknowledge, with respect to the right
of any Holder to pursue a remedy pursuant to Section 6.06 or 6.07 of this Indenture, the right of
any beneficial owner of Securities to pursue such remedy with respect to the portion of the Global
Security that represents such beneficial owner’s Securities as if such Definitive Securities had
been issued.

[FORM OF REVERSE SIDE OF INITIAL SECURITY]

103/8% Senior Note Due 2012

1. Interest

     PetroQuest Energy, Inc., a Delaware corporation (such corporation, and its successors and
assigns under the Indenture hereinafter referred to, being herein called the “Company”) and
PetroQuest Energy, L.L.C., a Louisiana limited liability company (such company, and its successors
and assigns under the Indenture hereinafter referred to, being herein called “PELLC” and, together
with the Company, the “Issuers”), jointly and severally promise to pay interest on the principal
amount of this Security at the rate per annum shown above; provided, however, that
if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional
interest will accrue on this Security at a rate of 0.50% per annum (increasing by an additional
0.50% per annum after each consecutive 90-day period that occurs after the date on which such
Registration default occurs up to a maximum additional interest rate of 1.50%) from and including
the date on which any such Registration Default shall occur to but excluding the date on which all
Registration Defaults have been cured. The Issuers will pay interest semiannually on May 15 and
November 15 of each year, commencing November 15, 2005. Interest on the Securities will accrue
from the most recent date to which interest has been paid or, if no interest has been paid, from
May 11, 2005. Interest will be computed on the basis of a 360-day year of twelve 30-day months.
The Issuers will pay interest on overdue principal at the rate borne by this Security plus 1.0% per
annum, and it will pay interest on overdue installments of interest at the same rate to the extent
lawful.

2. Method of Payment

     The Issuers will pay interest on the Securities (except defaulted interest) to the Persons who
are registered holders of Securities at the close of business on the May 1 or November 1 next
preceding the interest payment date even if Securities are canceled after the record date and on or
before the interest payment date. Holders must surrender Securities to a Paying Agent to collect
principal payments. The Issuers will pay principal and interest in money of the United States that
at the time of payment is legal tender for payment of public and private debts. Payments in
respect of the Securities represented by a Global Security (including principal, premium and
interest) will be made by wire transfer of immediately available funds to the accounts specified by
the Depository. The Issuers will make all payments in respect of a certificated Security
(including principal, premium and interest) by mailing a check to the registered address of each
Holder thereof; provided, however, that payments on a certificated Security will be
made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United
States if such Holder elects payment by wire transfer by giving written notice to the Trustee or
the Paying Agent to such effect designating such account no later than 30 days immediately
preceding the relevant due date for payment (or such other date as the Trustee may accept in its
discretion).

3. Paying Agent and Registrar

     Initially, The Bank of New York Trust Company, N.A., a national banking association (the
“Trustee”), will act as Paying Agent and Registrar. The Company may appoint and change any Paying
Agent, Registrar or co-registrar without notice. The Company or any of its domestically
incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or co-registrar.

4. Indenture

     The Issuers issued the Securities under an Indenture dated as of May 11, 2005 (“Indenture”),
among the Company, PELLC, the Subsidiary Guarantors and the Trustee. The terms of the Securities
include those stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) (the “Act”) as in effect on the
date of the Indenture. Terms defined in the Indenture and not defined herein have the meanings
ascribed thereto in the Indenture. The Securities are subject to all such terms, and
Securityholders are referred to the Indenture and the Act for a statement of those terms.

     The Securities are general unsecured obligations of the Issuers. The Issuers shall be
entitled, subject to their compliance with Section 4.03 of the Indenture, to issue Additional
Securities pursuant to Section 2.13 of the Indenture. The Initial Securities issued on the Issue
Date, any Additional Securities and all Exchange Securities or Private Exchange Securities issued
in exchange therefor will be treated as a single class for all purposes under the Indenture. The
Indenture contains covenants that limit the ability of the Company and its subsidiaries to incur
additional indebtedness; pay dividends or distributions on, or redeem or repurchase capital stock;
make investments; issue or sell capital stock of subsidiaries; engage in transactions with
affiliates; create liens on assets; transfer or sell assets; guarantee indebtedness; restrict
dividends or other payments of subsidiaries; consolidate, merge or transfer all or substantially
all of its assets and the assets of its subsidiaries; and engage in sale/leaseback transactions.
These covenants are subject to important exceptions and qualifications.

5. Optional Redemption

     Except as set forth below, the Issuers shall not be entitled to redeem the Securities.

     On and after May 15, 2009, the Issuers shall be entitled at their option to redeem all or a
portion of the Securities upon not less than 30 nor more than 60 days’ notice, at the redemption
prices (expressed in percentages of principal amount on the redemption date), plus accrued interest
to the redemption date (subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date), if redeemed during the 12-month period
commencing on May 15 of the years set forth below:

 

 

	 	 	 	 	 
	 	 	Redemption	 
	Period	 	Price	 
	2009
	 	 	105.188	%
	2010
	 	 	102.594	%
	2011
	 	 	100.000	%

     In addition, prior to May 15, 2008, the Issuers shall be entitled at their option on one or
more occasions to redeem Securities (which includes Additional Securities, if any) in an aggregate
principal amount not to exceed 35% of the original aggregate principal amount of the Securities
(which includes Additional Securities, if any) at a redemption price (expressed as a percentage of
principal amount) of 110.375%, plus accrued and unpaid interest to the redemption date, with the
net cash proceeds from one or more Equity Offerings; provided, however, that (1) at
least 65% of such aggregate principal amount of Securities (which includes Additional Securities,
if any) remains outstanding immediately after the occurrence of each such redemption (other than
Securities held, directly or indirectly, by the Company or its Affiliates); and (2) each such
redemption occurs within 90 days after the date of the related Equity Offering.

6. Notice of Redemption

     Notice of redemption will be mailed at least 30 days but not more than 60 days before the
redemption date to each Holder of Securities to be redeemed at his registered address. Securities
in denominations larger than $1,000 principal amount may be redeemed in part but only in whole
multiples of $1,000. If money sufficient to pay the redemption price of and accrued interest on
all Securities (or portions thereof) to be redeemed on the redemption date is deposited with the
Paying Agent on or before the redemption date and certain other conditions are satisfied, on and
after such date interest ceases to accrue on such Securities (or such portions thereof) called for
redemption.

7. Put Provisions

     Upon a Change of Control, any Holder of Securities will have the right to cause the Issuers to
repurchase all or any part of the Securities of such Holder at a repurchase price equal to 101% of
the principal amount of the Securities to be repurchased plus accrued interest to the date of
repurchase (subject to the right of holders of record on the relevant record date to receive
interest due on the related interest payment date) as provided in, and subject to the terms of, the
Indenture.

8. Guaranty

     The payment by the Issuers of the principal of, and premium and interest on, the Securities is
fully and unconditionally guaranteed on a joint and several senior basis by each of the Subsidiary
Guarantors to the extent set forth in the Indenture.

 

 

 10

9. Denominations; Transfer; Exchange

     The Securities are in registered form without coupons in denominations of $1,000 principal
amount and whole multiples of $1,000. A Holder may transfer or exchange Securities in accordance
with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture. The Registrar need not register the transfer of or exchange any Securities selected
for redemption (except, in the case of a Security to be redeemed in part, the portion of the
Security not to be redeemed) or any Securities for a period of 15 days before a selection of
Securities to be redeemed or 15 days before an interest payment date.

10. Persons Deemed Owners

     The registered Holder of this Security may be treated as the owner of it for all purposes.

11. Unclaimed Money

     If money for the payment of principal or interest remains unclaimed for two years, the Trustee
or Paying Agent shall pay the money back to the Issuers at their request unless an abandoned
property law designates another Person. After any such payment, Holders entitled to the money must
look only to the Issuers and not to the Trustee for payment.

12. Discharge and Defeasance

     Subject to certain conditions, the Issuers at any time shall be entitled to terminate some or
all of their obligations under the Securities and the Indenture if the Issuers deposit with the
Trustee money or U.S. Government Obligations for the payment of principal and interest on the
Securities to redemption or maturity, as the case may be.

13. Amendment; Waiver

     Subject to certain exceptions set forth in the Indenture, (a) the Indenture and the Securities
may be amended with the written consent of the Holders of at least a majority in principal amount
outstanding of the Securities and (b) any default or noncompliance with any provision may be waived
with the written consent of the Holders of a majority in principal amount outstanding of the
Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any
Securityholder, the Issuers, the Subsidiary Guarantors and the Trustee shall be entitled to amend
the Indenture or the Securities to cure any ambiguity, omission, defect or inconsistency, or to
comply with Article 5 of the Indenture, or to provide for uncertificated Securities in addition to
or in place of certificated Securities, or to add guarantees with respect to the Securities,
including Subsidiary Guaranties, or to secure the Securities, or to add additional covenants or
surrender rights and powers conferred on the Issuers or the Subsidiary Guarantors, or to comply
with any requirement of the SEC in connection with qualifying the Indenture under the Act, or to
make any change that does not adversely

 

 

 11

affect the rights of any Securityholder, or to make amendments to provisions of the Indenture
relating to the form, authentication, transfer and legending of the Securities.

14. Defaults and Remedies

     Under the Indenture, Events of Default include (a) default for 30 days in payment of interest
on the Securities; (b) default in payment of principal on the Securities at maturity, upon
redemption pursuant to paragraph 5 of the Securities, upon acceleration or otherwise, or failure by
the Issuers to redeem or purchase Securities when required; (c) failure by the Issuers or any
Subsidiary Guarantor to comply with other agreements in the Indenture or the Securities, in certain
cases subject to notice and lapse of time; (d) certain accelerations (including failure to pay
within any grace period after final maturity) of other Indebtedness of the Issuers, any Subsidiary
Guarantor or any Significant Subsidiary if the amount accelerated (or so unpaid) exceeds $5
million; (e) certain events of bankruptcy or insolvency with respect to the Issuers, the Subsidiary
Guarantors and the Significant Subsidiaries; (f) certain judgments or decrees for the payment of
money in excess of $5 million; and (g) certain defaults with respect to Subsidiary Guaranties. If
an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the Securities may declare all the Securities to be due and payable
immediately. Certain events of bankruptcy or insolvency are Events of Default which will result in
the Securities being due and payable immediately upon the occurrence of such Events of Default.

     Securityholders may not enforce the Indenture or the Securities except as provided in the
Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives
indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in
principal amount of the Securities may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in
payment of principal or interest) if it determines that withholding notice is in the interest of
the Holders.

15. Trustee Dealings with the Company

     Subject to certain limitations imposed by the Act, the Trustee under the Indenture, in its
individual or any other capacity, may become the owner or pledgee of Securities and may otherwise
deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise
deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

16. No Recourse Against Others

     A director, officer, employee, incorporator or stockholder, as such, of the Issuers or the
Trustee shall not have any liability for any obligations of the Issuers under the Securities or the
Indenture or for any claim based on, in respect of or by reason of such obligations or their
creation. By accepting a Security, each Securityholder waives

 

 

 12

and releases all such liability. The waiver and release are part of the consideration for the
issue of the Securities.

17. Authentication

     This Security shall not be valid until an authorized signatory of the Trustee (or an
authenticating agent) manually signs the certificate of authentication on the other side of this
Security.

18. Abbreviations

     Customary abbreviations may be used in the name of a Securityholder or an assignee, such as
TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with
rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift
to Minors Act).

19. CUSIP Numbers

     The Issuers have caused CUSIP, ISIN and Common Code numbers to be printed on the Securities
and has directed the Trustee to use such numbers in notices of redemption as a convenience to
Securityholders. No representation is made as to the accuracy of such numbers either as printed on
the Securities or as contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

20. Holders’ Compliance with Registration Rights Agreement

     Each Holder of a Security, by acceptance hereof, acknowledges and agrees to the provisions of
the Registration Rights Agreement, including the obligations of the Holders with respect to a
registration and the indemnification of the Issuers to the extent provided therein.

[FORM OF REVERSE SIDE OF [EXCHANGE] SECURITY

[OR PRIVATE EXCHANGE SECURITY]]

10 3/8% Senior Note Due 2012

1. Interest

     PetroQuest Energy, Inc., a Delaware corporation (such corporation, and its successors and
assigns under the Indenture hereinafter referred to, being herein called the “Company”), and
PetroQuest Energy, L.L.C., a Louisiana limited liability company (such company, and its successors
and assigns under the Indenture hereinafter referred to, being herein called “PELLC” and, together
with the Company, the “Issuers”), jointly and severally promise to pay interest on the principal
amount of this Security at the rate per annum shown above[; provided, however, that
if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional
interest will accrue on this Security at a rate of 0.50% per annum (increasing by an additional
0.50% per annum after each consecutive 90-day period that occurs after the date on which such
Registration default occurs up to a maximum additional interest rate of 1.50%) from and including
the date on which any such Registration Default shall occur to but excluding the date on which all
Registration Defaults have been cured.]1 The Issuers will pay interest semiannually on
May 15 and November 15 of each year, commencing November 15, 2005. Interest on the Securities will
accrue from the most recent date to which interest has been paid or, if no interest has been paid,
from May 11, 2005. Interest will be computed on the basis of a 360-day year of twelve 30-day
months. The Issuers will pay interest on overdue principal at the rate borne by this Security plus
1.0% per annum, and it will pay interest on overdue installments of interest at the same rate to
the extent lawful.

2. Method of Payment

     The Issuers will pay interest on the Securities (except defaulted interest) to the Persons who
are registered holders of Securities at the close of business on the May 1 or November 1 next
preceding the interest payment date even if Securities are canceled after the record date and on or
before the interest payment date. Holders must surrender Securities to a Paying Agent to collect
principal payments. The Issuers will pay principal and interest in money of the United States that
at the time of payment is legal tender for payment of public and private debts. Payments in
respect of the Securities represented by a Global Security (including principal, premium and
interest) will be made by wire transfer of immediately available funds to the accounts specified by
the Depository. The Issuers will make all payments in respect of a certificated Security
(including principal, premium and interest) by mailing a check to the registered address of each
Holder thereof; provided, however, that payments on a certificated Security will be
made by wire

	1Insert if at the date of issuance of the Exchange
Security or Private Exchange Security (as the case may be) any Registration
Default has occurred with respect to the related Initial Securities during the
interest period in which such date of issuance occurs.

 

 

 5

transfer to a U.S. dollar account maintained by the payee with a bank in the United States if
such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying
Agent to such effect designating such account no later than 30 days immediately preceding the
relevant due date for payment (or such other date as the Trustee may accept in its discretion).

3. Paying Agent and Registrar

     Initially, The Bank of New York Trust Company, N.A., a national banking association (the
“Trustee”), will act as Paying Agent and Registrar. The Company may appoint and change any Paying
Agent, Registrar or co-registrar without notice. The Company or any of its domestically
incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or co-registrar.

4. Indenture

     The Issuers issued the Securities under an Indenture dated as of May 11, 2005 (“Indenture”),
among the Company, PELLC, the Subsidiary Guarantors and the Trustee. The terms of the Securities
include those stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the
Indenture (the “Act”). Terms defined in the Indenture and not defined herein have the meanings
ascribed thereto in the Indenture. The Securities are subject to all such terms, and
Securityholders are referred to the Indenture and the Act for a statement of those terms.

     The Securities are general unsecured obligations of the Issuers. The Issuers shall be
entitled, subject to their compliance with Section 4.03 of the Indenture, to issue Additional
Securities pursuant to Section 2.13 of the Indenture. The Initial Securities issued on the Issue
Date, any Additional Securities and all Exchange Securities or Private Exchange Securities issued
in exchange therefor will be treated as a single class for all purposes under the Indenture. The
Indenture contains covenants that limit the ability of the Company and its subsidiaries to incur
additional indebtedness; pay dividends or distributions on, or redeem or repurchase capital stock;
make investments; issue or sell capital stock of subsidiaries; engage in transactions with
affiliates; create liens on assets; transfer or sell assets; guarantee indebtedness; restrict
dividends or other payments of subsidiaries; consolidate, merge or transfer all or substantially
all of its assets and the assets of its subsidiaries; and engage in sale/leaseback transactions.
These covenants are subject to important exceptions and qualifications.

5. Optional Redemption

     Except as set forth below, the Issuers shall not be entitled to redeem the Securities.

     On and after May 15, 2009, the Issuers shall be entitled at their option to redeem all or a
portion of the Securities upon not less than 30 nor more than 60 days’ notice, at the redemption
prices (expressed in percentages of principal amount on the redemption date), plus accrued interest
to the redemption date (subject to the right of Holders of

 

 

 6

record on the relevant record date to receive interest due on the relevant interest payment
date), if redeemed during the 12-month period commencing on May 15 of the years set forth below:

	 	 	 	 	 
	 	 	Redemption	 
	Period	 	Price	 
	2009
	 	 	105.188	%
	2010
	 	 	102.594	%
	2011
	 	 	100.000	%

     In addition, prior to May 15, 2008, the Issuers shall be entitled at their option on one or
more occasions to redeem Securities (which includes Additional Securities, if any) in an aggregate
principal amount not to exceed 35% of the original aggregate principal amount of the Securities
(which includes Additional Securities, if any) at a redemption price (expressed as a percentage of
principal amount) of 110.375%, plus accrued and unpaid interest to the redemption date, with the
net cash proceeds from one or more Equity Offerings; provided, however, that (1) at
least 65% of such aggregate principal amount of Securities (which includes Additional Securities,
if any) remains outstanding immediately after the occurrence of each such redemption (other than
Securities held, directly or indirectly, by the Company or its Affiliates); and (2) each such
redemption occurs within 90 days after the date of the related Equity Offering.

6. Notice of Redemption

     Notice of redemption will be mailed at least 30 days but not more than 60 days before the
redemption date to each Holder of Securities to be redeemed at his registered address. Securities
in denominations larger than $1,000 principal amount may be redeemed in part but only in whole
multiples of $1,000. If money sufficient to pay the redemption price of and accrued interest on
all Securities (or portions thereof) to be redeemed on the redemption date is deposited with the
Paying Agent on or before the redemption date and certain other conditions are satisfied, on and
after such date interest ceases to accrue on such Securities (or such portions thereof) called for
redemption.

7. Put Provisions

     Upon a Change of Control, any Holder of Securities will have the right to cause the Issuers to
repurchase all or any part of the Securities of such Holder at a repurchase price equal to 101% of
the principal amount of the Securities to be repurchased plus accrued interest to the date of
repurchase (subject to the right of holders of record on the relevant record date to receive
interest due on the related interest payment date) as provided in, and subject to the terms of, the
Indenture.

8. Guaranty

     The payment by the Issuers of the principal of, and premium and interest on, the Securities is
fully and unconditionally guaranteed on a joint and several senior basis by each of the Subsidiary
Guarantors to the extent set forth in the Indenture.

 

 

 7

9. Denominations; Transfer; Exchange

     The Securities are in registered form without coupons in denominations of $1,000 principal
amount and whole multiples of $1,000. A Holder may transfer or exchange Securities in accordance
with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture. The Registrar need not register the transfer of or exchange any Securities selected
for redemption (except, in the case of a Security to be redeemed in part, the portion of the
Security not to be redeemed) or any Securities for a period of 15 days before a selection of
Securities to be redeemed or 15 days before an interest payment date.

10. Persons Deemed Owners

     The registered Holder of this Security may be treated as the owner of it for all purposes.

11. Unclaimed Money

     If money for the payment of principal or interest remains unclaimed for two years, the Trustee
or Paying Agent shall pay the money back to the Issuers at their request unless an abandoned
property law designates another Person. After any such payment, Holders entitled to the money must
look only to the Issuers and not to the Trustee for payment.

12. Discharge and Defeasance

     Subject to certain conditions, the Issuers at any time shall be entitled to terminate some or
all of their obligations under the Securities and the Indenture if the Issuers deposit with the
Trustee money or U.S. Government Obligations for the payment of principal and interest on the
Securities to redemption or maturity, as the case may be.

13. Amendment; Waiver

     Subject to certain exceptions set forth in the Indenture, (a) the Indenture and the Securities
may be amended with the written consent of the Holders of at least a majority in principal amount
outstanding of the Securities and (b) any default or noncompliance with any provision may be waived
with the written consent of the Holders of a majority in principal amount outstanding of the
Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any
Securityholder, the Issuers, the Subsidiary Guarantors and the Trustee shall be entitled to amend
the Indenture or the Securities to cure any ambiguity, omission, defect or inconsistency, or to
comply with Article 5 of the Indenture, or to provide for uncertificated Securities in addition to
or in place of certificated Securities, or to add guarantees with respect to the Securities,
including Subsidiary Guaranties, or to secure the Securities, or to add additional covenants or
surrender rights and powers conferred on the Issuers or the Subsidiary Guarantors, or to comply
with any requirement of the SEC in connection with qualifying the Indenture under the Act, or to
make any change that does not adversely affect the rights of any

 

 

 8

Securityholder, or to make amendments to provisions of the Indenture relating to the form,
authentication, transfer and legending of the Securities.

14. Defaults and Remedies

     Under the Indenture, Events of Default include (a) default for 30 days in payment of interest
on the Securities; (b) default in payment of principal on the Securities at maturity, upon
redemption pursuant to paragraph 5 of the Securities, upon acceleration or otherwise, or failure by
the Issuers to redeem or purchase Securities when required; (c) failure by the Issuers or any
Subsidiary Guarantor to comply with other agreements in the Indenture or the Securities, in certain
cases subject to notice and lapse of time; (d) certain accelerations (including failure to pay
within any grace period after final maturity) of other Indebtedness of the Issuers, any Subsidiary
Guarantor or any Significant Subsidiary if the amount accelerated (or so unpaid) exceeds $5
million; (e) certain events of bankruptcy or insolvency with respect to the Issuers, the Subsidiary
Guarantors and the Significant Subsidiaries; (f) certain judgments or decrees for the payment of
money in excess of $5 million; and (g) certain defaults with respect to Subsidiary Guaranties. If
an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the Securities may declare all the Securities to be due and payable
immediately. Certain events of bankruptcy or insolvency are Events of Default which will result in
the Securities being due and payable immediately upon the occurrence of such Events of Default.

     Securityholders may not enforce the Indenture or the Securities except as provided in the
Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives
indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in
principal amount of the Securities may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in
payment of principal or interest) if it determines that withholding notice is in the interest of
the Holders.

15. Trustee Dealings with the Company

     Subject to certain limitations imposed by the Act, the Trustee under the Indenture, in its
individual or any other capacity, may become the owner or pledgee of Securities and may otherwise
deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise
deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

16. No Recourse Against Others

     A director, officer, employee, incorporator or stockholder, as such, of the Issuers or the
Trustee shall not have any liability for any obligations of the Issuers under the Securities or the
Indenture or for any claim based on, in respect of or by reason of such obligations or their
creation. By accepting a Security, each Securityholder waives and

 

 

 9

releases all such liability. The waiver and release are part of the consideration for the
issue of the Securities.

17. Authentication

     This Security shall not be valid until an authorized signatory of the Trustee (or an
authenticating agent) manually signs the certificate of authentication on the other side of this
Security.

18. Abbreviations

     Customary abbreviations may be used in the name of a Securityholder or an assignee, such as
TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with
rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift
to Minors Act).

19. CUSIP Numbers

     The Issuers have caused CUSIP, ISIN and Common Code numbers to be printed on the Securities
and has directed the Trustee to use such numbers in notices of redemption as a convenience to
Securityholders. No representation is made as to the accuracy of such numbers either as printed on
the Securities or as contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

20. [Holders’ Compliance with Registration Rights Agreement

     Each Holder of a Security, by acceptance hereof, acknowledges and agrees to the provisions of
the Registration Rights Agreement, including the obligations of the Holders with respect to a
registration and the indemnification of the Issuers to the extent provided therein.]2

Corporate Secretary

Ladies and Gentlemen:

     This certificate is delivered to request a transfer of $[ ] principal amount of the 10?%
Senior Notes due 2012 (the “Securities”) of PetroQuest Energy, Inc. (the “Company”) and PetroQuest
Energy, L.L.C. (collectively, the “Issuers”).

     Upon transfer, the Securities would be registered in the name of the new beneficial owner as
follows:

Name:________________________

Address:______________________

Taxpayer ID Number:____________

     The undersigned represents and warrants to you that:

     1. We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or
(7) under the Securities Act of 1933, as amended (the “Securities Act”)), purchasing for our own
account or for the account of such an institutional “accredited investor” at least $250,000
principal amount of the Securities, and we are acquiring the Securities not with a view to, or for
offer or sale in connection with, any distribution in violation of the Securities Act. We have
such knowledge and experience in financial and business matters as to be capable of evaluating the
merits and risks of our investment in the Securities, and we invest in or purchase securities
similar to the Securities in the normal course of our business. We, and any accounts for which we
are acting, are each able to bear the economic risk of our or its investment.

     2. We understand that the Securities have not been registered under the Securities Act and,
unless so registered, may not be sold except as permitted in the following

 

 

 2

sentence. We agree on our own behalf and on behalf of any investor account for which we are
purchasing Securities to offer, sell or otherwise transfer such Securities prior to the date that
is two years after the later of the date of original issue and the last date on which the Company
or any affiliate of the Company was the owner of such Securities (or any predecessor thereto) (the
“Resale Restriction Termination Date”) only (i) to the Issuers, (ii) in the United States to a
person whom the seller reasonably believes is a qualified institutional buyer in a transaction
meeting the requirements of Rule 144A, (iii) to an institutional “accredited investor” within the
meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act that is an institutional
