theretofore deposited with the Trustee or any Paying Agent (other than the Company) in trust

provision of this Indenture, the Company shall furnish to the Trustee, if so requested by the
Trustee, an Officers’ Certificate stating that all conditions precedent, if any, provided for in
this Indenture relating to the proposed action have been complied with and an Opinion of Counsel

complied with, except that in the case of any such application or request as to which the
furnishing of such documents is specifically required by any provision of this Indenture relating
to such particular application or request, no additional certificate or opinion need be furnished.

     Every certificate or opinion with respect to compliance with a condition or covenant provided
for in this Indenture shall include:

     (a) a statement that each individual signing such certificate or opinion has read such
covenant or condition and the definitions herein relating thereto;

covenant has been complied with.

     SECTION 103. Form of Documents Delivered to Trustee.

     In any case where several matters are required to be certified by, or covered by an opinion

matters is in the possession of the Company, unless such counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations with respect to
such matters are erroneous.

8

 

     Where any Person is required to make, give or execute two or more applications, requests,
consents, certificates, statements, opinions or other instruments under this Indenture, they may,
but need not, be consolidated and form one instrument.

     SECTION 104. Acts of Holders.

     (a) Any request, demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one
or more instruments of substantially similar tenor signed by such Holders in person or by an agent
duly appointed in writing, and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the Trustee and, where it is
hereby expressly required, to the Company. Such instrument or instruments (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to
Section 601) conclusive in favor of the Trustee and the Company, if made in the manner provided in
this Section.

     (b) The fact and date of the execution by any Person of any such instrument or writing may be
proved by the affidavit of a witness of such execution or by a certificate of a notary public or
other officer authorized by law to take acknowledgments of deeds, certifying that the individual
signing such instrument or writing acknowledged to him the execution thereof. Where such execution
is by a signer acting in a capacity other than such signer’s individual capacity, such certificate
or affidavit shall also constitute sufficient proof of such signer’s authority. The fact and date
of the execution of any such instrument or writing, or the authority of the Person executing the
same, may also be proved in any other manner which the Trustee deems sufficient.

     (c) The ownership of Securities shall be proved by the Security Register. The Company may fix
any day as the record date for the purpose of determining the Holders of Securities of any series
entitled to give or take any request, demand, authorization, direction, notice, consent, waiver or
other action, or to vote on any action, authorized or permitted to be given or taken by Holders of
Securities of such series. If not set by the Company prior to the first solicitation of a Holder
of Securities of such series made by any Person in respect of any such action, or, in the case of
any such vote, prior to such vote, the record date for any such action or vote shall be the 30th
day (or, if later, the date of the most recent list of Holders required to be provided pursuant to
Section 701) prior to such first solicitation or vote, as the case may be. With regard to any
record date for action to be taken by the Holders of one or more series of Securities, only the
Holders of Securities of such series on such date (or their duly designated proxies) shall be
entitled to give or take, or vote on, the relevant action.

     (d) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the
Holder of any Security shall bind every future Holder of the same Security and the Holder of every
Security issued upon the registration of transfer thereof or in exchange therefor or in lieu
thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company
in reliance thereon, whether or not notation of such action is made upon such Security.

9

 

     SECTION 105. Notices, Etc., to Trustee and Company.

     Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or
other document provided or permitted by this Indenture to be made upon, given or furnished to, or
filed with,

     (a) the Trustee by any Holder or by the Company shall be sufficient for every purpose
hereunder (unless otherwise herein expressly provided) if made, given, furnished or filed in
writing to or with a Responsible Officer of the Trustee at its Corporate Trust Office,
Attention: Corporate Trust Department, or

     (b) the Company by the Trustee or by any Holder shall be sufficient for every purpose
hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class
postage prepaid, to the Company addressed to it at the address of its principal office
specified in the first paragraph of this instrument (Attention: Treasurer) or at any other
address previously furnished in writing to the Trustee by the Company.

     SECTION 106. Notice to Holders; Waiver.

     Where this Indenture provides for notice to Holders of any event, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, to each Holder affected by such event, at such Holder’s address as it
appears in the Security Register, not later than the latest date, and not earlier than the earliest
date, prescribed for the giving of such notice. In any case where notice to Holders is given by
mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where
this Indenture provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action taken in reliance upon
such waiver.

     In case by reason of the suspension of regular mail service or by reason of any other cause it
shall be impracticable to give such notice by mail, then such notification as shall be made by or
with the approval of the Trustee shall constitute a sufficient notification for every purpose
hereunder.

     SECTION 107. Compliance with Trust Indenture Act.

     This Indenture is subject to, and shall be governed by, the provisions of the Trust Indenture
Act that are required to be part of this Indenture. If any provision hereof limits, qualifies or
conflicts with a provision of the Trust Indenture Act that is required under the Trust Indenture
Act to be a part of and govern this Indenture, the provision of the Trust Indenture Act shall
control. If any provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to
this Indenture as so modified or to be excluded, as the case may be.

10

 

     SECTION 108. Effect of Headings and Table of Contents.

     The Article and Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

     SECTION 109. Successors and Assigns.

     All covenants and agreements in this Indenture by the Company or the Trustee shall bind its
successors and assigns, whether so expressed or not.

     SECTION 110. Separability Clause.

     In case any provision in this Indenture or in the Securities shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

     SECTION 111. Benefits of Indenture.

     Nothing in this Indenture or in the Securities, express or implied, shall give to any Person,
other than the parties hereto, any Authenticating Agent, any Paying Agent, any Securities
Registrar, and their successors hereunder and the Holders, any benefit or any legal or equitable
right, remedy or claim under this Indenture.

     SECTION 112. Governing Law.

     This Indenture and the Securities shall be governed by and construed in accordance with the
laws of the State of New York.

     SECTION 113. Legal Holidays.

     Except as may be otherwise specified with respect to any particular Securities, in any case
where any Interest Payment Date, Redemption Date or Stated Maturity of any Security shall not be a
Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture
or of the Securities) payment of interest or principal (and premium, if any) need not be made at
such Place of Payment on such date, but may be made on the next succeeding Business Day at such
Place of Payment with the same force and effect as if made on the Interest Payment Date or
Redemption Date, or at the Stated Maturity, provided that no interest shall accrue for the period
from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be.

substitutions and other variations as are required or permitted by this Indenture, and may have

     (o) any other terms of the series (which terms shall not be inconsistent with the

be substantially identical except as to denomination and except as may otherwise be provided by or
pursuant to the Board Resolution referred to above and, subject to Section 303, set forth, or

indenture supplemental hereto.

     If any of the terms of the series are established by action taken pursuant to a Board
Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or
an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of
the Officers’ Certificate setting forth the terms of the series.

     With respect to Securities of a series offered in a Periodic Offering, such Board Resolution
and Officers’ Certificate or supplemental indenture may provide general terms or parameters for
Securities of such series and provide either that the specific terms of particular Securities of
such series shall be specified in a Company Order or that such terms shall be determined by the
Company or its agents in accordance with other procedures specified in a Company Order as
contemplated by the third paragraph of Section 303.

     SECTION 302. Denominations.

     Unless otherwise provided in the applicable Officers’ Certificate or supplemental indenture,
the Securities of each series shall be issued in registered form without coupons in such
denominations as shall be specified as contemplated by Section 301. In the absence of any such
provisions with respect to the Securities of any series, the Securities of such series shall be
issuable in denominations of $1,000 or any amount in excess thereof which is an integral multiple
of $1,000.

     SECTION 303. Execution, Authentication, Delivery and Dating.

     The Securities shall be executed on behalf of the Company by its Chairman of the Board, its
President or one of its Vice Presidents, attested by its Secretary or one of its Assistant
Secretaries. The signature of any of these officers on the Securities may be manual or facsimile.

     Securities bearing the manual or facsimile signatures of individuals who were at any time the
proper officers of the Company shall bind the Company, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and delivery of such
Securities or did not hold such offices at the date of such Securities.

     At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities of any series executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and delivery of such
Securities, or, in the case of Securities offered in a Periodic Offering, from time to time in
accordance with such other procedures (including, without limitation, the receipt by the Trustee of
electronic instructions from the Company or its duly authorized agents, promptly confirmed in
writing by the Company) acceptable to the Trustee as may be specified from time to time by a
Company Order for establishing the specific terms of particular Securities being so offered, and
the Trustee in accordance with the Company Order shall authenticate and deliver such Securities.
If the form or forms or terms of the Securities of the series have been established by

15

 

or pursuant
to one or more Board Resolutions as permitted by Sections 201 and 301, in authenticating such
Securities and accepting the additional responsibilities under this Indenture in relation to such
Securities, the Trustee shall be entitled to receive, and (subject to Section 601) shall be fully
protected in relying upon, an Opinion of Counsel stating,

     (a) that the form or forms of such Securities have been established in conformity with
the provisions of this Indenture;

     (b) that the terms of such Securities have been established in conformity with the
provisions of this Indenture; and

     (c) that such Securities, when authenticated and delivered by the Trustee and issued by
the Company in the manner and subject to any conditions specified in such Opinion of
Counsel, will constitute valid and legally binding obligations of the Company,
enforceable in accordance with their terms, subject to bankruptcy, insolvency,
reorganization and other laws of general applicability relating to or affecting the
enforcement of creditors’ rights and to general equity principles.

provided, however, that, with respect to Securities of a series offered in a Periodic Offering, the
Trustee shall be entitled to receive such Opinion of Counsel in connection only with the first
authentication of each form of Securities of such series and that the opinions described in Clauses
(b) and (c) above may state, respectively, that

     (i) if the terms of such Securities are to be established pursuant to a Company Order
or pursuant to such procedures as may be specified from time to time by a Company Order, all
as contemplated by a Board Resolution or action taken pursuant thereto, such terms will have
been duly authorized by the Company and established in conformity with the provisions of
this Indenture; and

     (ii) that such Securities, when executed by the Company, completed, authenticated and
delivered by the Trustee in accordance with this Indenture, and issued and delivered by the
Company and paid for, all in accordance with any agreement of the Company relating to the
offering, issuance and sale of such Securities, will be duly issued under this Indenture and
will constitute valid and legally binding obligations of the Company, enforceable in
accordance with their terms, subject to bankruptcy, insolvency, reorganization, moratorium
and other laws relating to or affecting generally the enforcement of creditors’ rights and
to general principles of equity.

     With respect to Securities of a series offered in a Periodic Offering, the Trustee may rely,
as to the authorization by the Company of any of such Securities, the form or forms and terms
thereof and the legality, validity, binding effect and enforceability thereof, upon the Opinion of
Counsel, Company Order and other documents delivered pursuant to Sections 201 and 301 and this
Section, as applicable, in connection with the first authentication of a form of Securities of such
series and it shall not be necessary for the Company to deliver such Opinion of Counsel and other
documents (except as may be required by the specified other procedures, if any, referred to above)
at or prior to the time of authentication of each Security of such series unless and until the
Trustee receives notice that such Opinion of Counsel or other documents have been superseded

16

 

or
revoked, and may assume compliance with any conditions specified in such Opinion of Counsel (other
than any conditions to be performed by the Trustee). If such form or forms or terms have been so
established, the Trustee shall not be required to authenticate such Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities
under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable
to the Trustee.

     Each Security shall be dated the date of its authentication.

     No Security shall be entitled to any benefit under this Indenture or be valid or obligatory
for any purpose unless there appears on such Security a certificate of authentication substantially
in the form provided for herein executed by the Trustee by manual signature, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such Security has been
duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture.
Notwithstanding the foregoing, if any Security shall have been authenticated and delivered
hereunder but never issued and sold by the Company, and the Company shall deliver such Security to
the Trustee for cancellation as provided in Section 309 together with a written statement (which
need not comply with Section 102 and need not be accompanied by an Opinion of Counsel) stating that
such Security has never been issued and sold by the Company, for all purposes of this Indenture
such Security shall be deemed never to have been authenticated and delivered hereunder and shall
never be entitled to the benefits of this Indenture.

     SECTION 304. Temporary Securities.

     Pending the preparation of definitive Securities of any series, the Company may execute, and
upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are
printed, lithographed, typewritten or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as the officers
executing such Securities may determine, as evidenced by their execution of such Securities.

     If temporary Securities of any series are issued, the Company will cause definitive Securities
of that series to be prepared without unreasonable delay. After the preparation of definitive
Securities of such series, the temporary Securities of such series shall be exchangeable for
definitive Securities of like tenor of such series upon surrender of the temporary Securities of
such series at the office or agency of the Company in a Place of Payment for that series, without
charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of
any series the Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Securities of the same series and of like tenor and
of any authorized denominations. Until so exchanged the temporary Securities of any series shall
in all respects be entitled to the same benefits under this Indenture as definitive Securities of
such series and tenor.

     SECTION 305. Registration, Registration of Transfer and Exchange.

     The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register
(the “Security Register”) in which, subject to such reasonable regulations as it may

17

 

prescribe, the
Company shall provide for the registration of Securities and of transfers of Securities. The
Trustee is hereby appointed “Security Registrar” for the purpose of registering Securities and
transfers of Securities as herein provided.

     Upon surrender for registration of transfer of any Security of any series at the office or
agency of the Company in any Place of Payment for such series, the Company shall execute and the
Trustee shall authenticate and deliver (in the name of the designated transferee or transferees)
one or more new Securities of the same series, of any authorized denominations and of a like
aggregate principal amount and tenor.

     At the option of the Holder, Securities of any series may be exchanged for other Securities of
the same series, of any authorized denominations and of a like aggregate principal amount and
tenor, upon surrender of the Securities to be exchanged at the office or agency of the Company in
any Place of Payment for such series. Whenever any Securities are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the
Holder making the exchange is entitled to receive.

     All Securities issued upon any registration of transfer or exchange of Securities shall be the
valid obligations of the Company evidencing the same debt, and entitled to the same benefits under
this Indenture as the Securities surrendered upon such registration of transfer or exchange.

     Every Security presented or surrendered for registration of transfer or for exchange shall (if
so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security Registrar duly
executed, by the Holder thereof or such Holder’s attorney duly authorized in writing.

     No service charge shall be made for any registration of transfer or exchange of Securities,
but the Company may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or exchange of
Securities, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

     The Company may but shall not be required (i) to issue, register the transfer of or exchange
Securities of any series during a period beginning at the opening of business 15 days before the
day of the mailing of a notice of redemption of Securities of that series selected for redemption
under Section 1103 and ending at the close of business on the day of such mailing, or (ii) to
register the transfer of or exchange any Security so selected for redemption in whole or in part,
except the unredeemed portion of any Security being redeemed in part.

     Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 301,
any Global Security shall be exchangeable pursuant to this Section 305 for Securities registered in
the name of Persons other than the Depositary for such Security or its nominee only if (i) such
Depositary notifies the Company that it is unwilling or unable to continue as Depositary for such
Global Security or if at any time such Depositary ceases to be a clearing agency registered under
the Exchange Act, (ii) the Company executes and delivers to the Trustee a Company Order that such
Global Security shall be so exchangeable or (iii) there shall have occurred and be continuing an
Event of Default with respect to the Securities of such

18

 

series. Upon the occurrence in respect of
any Global Security of any series of any one or more of the conditions specified in Clauses (i),
(ii) or (iii) of the preceding sentence or such other conditions as may be specified as
contemplated by Section 301 for such series, such Global Security may be exchanged for Securities
not bearing the legend specified in Section 203 and registered in the names of such Persons as may
be specified by the Depositary (including Persons other than the Depositary).

     Notwithstanding any other provision of this Indenture, a Global Security may not be
transferred except as a whole by the Depositary for such Global Security to a nominee of the
Depositary or by a nominee of the Depositary to the Depositary or another nominee of the
Depositary.

     SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities.

     If any mutilated Security is surrendered to the Trustee, the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and
of like tenor and principal amount and bearing a number not contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction
of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be
required by them to save each of them and any agent of either of them harmless, then, in the
absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and upon its written request the Trustee shall authenticate
and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same
series and of like tenor and principal amount and bearing a number not contemporaneously
outstanding.

     In case any such mutilated, destroyed, lost or stolen Security has become or is about to
become due and payable, the Company in its discretion may, instead of issuing a new Security, pay
such Security.

     Upon the issuance of any new Security under this Section, the Company may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Trustee) connected
therewith.

     Every new Security of any series issued pursuant to this Section in lieu of any destroyed,
lost or stolen Security shall constitute an original additional contractual obligation of the
Company whether or not the destroyed, lost or stolen Security shall be at any time enforceable by
anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately
with any and all other Securities of that series duly issued hereunder.

     The provisions of this Section are exclusive and shall preclude (to the extent lawful) all
other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost
or stolen Securities.

19

 

     SECTION 307. Payment of Interest; Interest Rights Preserved.

     Unless otherwise provided as contemplated by Section 301 with respect to any series of
Securities, interest on any Security which is payable, and is punctually paid or duly provided for,
on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or
more Predecessor Securities) is registered in the Security Register at the close of business
on the Regular Record Date for such Interest Payment Date.

     Any interest on any Security of any series which is payable but is not punctually paid or duly
provided for on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith
cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such
Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as
provided in Clause (a) or (b) below:

     (a) The Company may elect to make payment of any Defaulted Interest to the Persons in
whose names the Securities of such series (or their respective Predecessor Securities) are
registered at the close of business on a Special Record Date for the payment of such
Defaulted Interest, which shall be fixed in the following manner. The Company shall notify
the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each
Security of such series and the date of the proposed payment, and at the same time the
Company shall deposit with the Trustee an amount of money equal to the aggregate amount
proposed to be paid in respect of such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such
money when deposited to be held in trust for the benefit of the Persons entitled to such
Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special
Record Date for the payment of such Defaulted Interest which shall be not more than 15 days
and not less than 10 days prior to the date of the proposed payment and not less than 10
days after the receipt by the Trustee of the notice of the proposed payment. The Trustee
shall promptly notify the Company of such Special Record Date and, in the name and at the
expense of the Company, shall cause notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to
each Holder of Securities of such series at such Holder’s address as it appears in the
Security Register, not less than 10 days prior to such Special Record Date. Notice of the
proposed payment of such Defaulted Interest and the Special Record Date therefor having been
so mailed, such Defaulted Interest shall be paid to the Persons in whose names the
Securities of such series (or their respective Predecessor Securities) are registered at the
close of business on such Special Record Date and shall no longer be payable pursuant to the
following Clause (b).

     (b) The Company may make payment of any Defaulted Interest on the Securities of any
series in any other lawful manner not inconsistent with the requirements of any securities
exchange on which such Securities may be listed, and upon such notice as may be required by
such exchange, if, after notice given by the Company to the Trustee of the proposed payment
pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee.

20

 

     Subject to the foregoing provisions of this Section, each Security delivered under this
Indenture upon registration of transfer of, or in exchange for, or in lieu of, any other Security
shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

     SECTION 308. Persons Deemed Owners.

     Prior to due presentment of a Security for registration of transfer, the Company, the Trustee
and any agent of the Company or the Trustee may treat the Person in whose name such Security is
registered in the Security Register as the owner of such Security for the purpose of receiving
payment of principal of (and premium, if any) and (subject to Section 307) interest on such
Security and for all other purposes whatsoever, whether or not such Security be overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary.

     No holder of any beneficial interest in any Global Security held on its behalf by a Depositary
(or its nominee) shall have any rights under this Indenture with respect to such Global Security or
any Security represented thereby, and such Depositary may be treated by the Company, the Trustee,
and any agent of the Company or the Trustee as the owner of such Global Security or any Security
represented thereby for all purposes whatsoever. Notwithstanding the foregoing, with respect to
any Global Security, nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy or other
authorization furnished by a Depositary or impair, as between a Depositary and such holders of
beneficial interest, the operation of customary practices governing the exercise of the rights of
the Depositary (or its nominees) as Holder of any Security.

     SECTION 309. Cancellation.

     All Securities surrendered for payment, redemption, registration of transfer or exchange or
for credit against any sinking fund payment shall, if surrendered to any Person other than the
Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Company may at any
time deliver to the Trustee for cancellation any Securities previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the
Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold, and all Securities so
delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities canceled as provided in this Section, except as expressly
permitted by this Indenture. All canceled Securities held by the Trustee shall be destroyed unless
otherwise directed by a Company Order.

     SECTION 310. Computation of Interest.

     Except as otherwise specified as contemplated by Section 301 for Securities of any series,
interest on the Securities of each series shall be computed on the basis of a 360-day year of
twelve 30-day months.

21

 

     SECTION 311. Payment to be in Proper Currency.

     In the case of any Securities denominated in any currency (the “Required Currency”) other than
United States of America dollars, except as otherwise provided therein, the obligation of the
Company to make any payment of principal, premium or interest thereon shall not be discharged or
satisfied by any tender by the Company, or recovery by the Trustee, in any currency other than the
Required Currency, except to the extent that such tender or recovery shall result in the Trustee
timely holding the full amount of the Required Currency then due and payable. If any such tender
or recovery is in a currency other than the Required Currency, the Trustee may take such actions as
it considers appropriate to exchange such currency for the Required Currency. The costs and risks
of any such exchange, including without limitation the risks of delay and exchange rate
fluctuation, shall be borne by the Company, the Company shall remain fully liable for any shortfall
or delinquency in the full amount of Required Currency then due and payable, and in no
circumstances shall the Trustee be liable therefor except in the case of its negligence or willful
misconduct.

be deposited with the Trustee as trust funds in trust for the purpose an amount in
the currency in which such Securities are payable (or, at the election of the
Company in the case of Securities payable in United States dollars, direct
obligations of, or obligations the principal of and interest on which are fully
guaranteed by, the United States of America (other than obligations subject to
prepayment, redemption or call prior to their stated maturity) as will be, together
with the predetermined and certain income to accrue thereon (without consideration
of any reinvestment thereof)) sufficient to pay and discharge the entire
indebtedness on such Securities not theretofore delivered to the Trustee for

Company to the Trustee under Section 607, the obligations of the Trustee to any Authenticating
Agent under Section 614, and, if money shall have been deposited with the Trustee pursuant to

Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine,
to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose
payment such money has been deposited with the Trustee but such money need not be segregated from
other funds except to the extent required by law.

     SECTION 403. Defeasance and Discharge of Indenture.

payable in United States of America dollars, the Company shall be deemed to have paid and
discharged the entire indebtedness on all the Outstanding Securities of such series on the 91st day
after the date of the deposit referred to in subparagraph (a) hereof, and the provisions of this
Indenture, as it relates to such Outstanding Securities, shall no longer be in effect (and the
Trustee, at the expense of the Company, shall at Company Request, execute proper instruments

24

 

income, gain or
loss for Federal income tax purposes as a result of such deposits, defeasance and discharge
and will be subject to Federal income tax on the same amount and in the same manner and at
the same times, as would have been the case if such deposit, defeasance and discharge had
not occurred; and

     (g) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that all conditions precedent relating to the defeasance contemplated
by this Section have been complied with.

ARTICLE FIVE

REMEDIES

otherwise provided with respect to Securities of any series pursuant to Section 301(k), means any
one of the following events (whatever the reason for such Event of Default and whether it shall be
voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or

after there has been given, by registered or certified mail, to the
Company by the Trustee or to the Company and the Trustee by the Holders of at least 25%
in aggregate principal amount of the Outstanding Securities of that series a written notice
specifying such default or breach and requiring it to be remedied and stating that such
notice is a “Notice of Default” hereunder; or

     (e) an event of default, as defined in any indenture or instrument under which the
Company or any Subsidiary shall have outstanding at least $75,000,000 aggregate principal
amount of indebtedness for money borrowed, shall happen and be continuing and such
indebtedness shall, as a result thereof, have been accelerated so that the same shall be or

and payable, and such acceleration shall not be rescinded or annulled

25

 

within 10 days after
notice thereof shall have been given, by registered or certified mail, to the Company by the
Trustee, or to the Company and the Trustee by the Holders of at least 25% in aggregate
principal amount of the Securities at the time Outstanding; provided, however, that if such
event of default under such indenture or instrument shall be remedied or cured by the
Company or waived by the Holders of such indebtedness, then, unless the Securities of any
series shall have been accelerated as provided herein, the Event of Default hereunder by
reason thereof shall be deemed likewise to have been thereupon remedied, cured or waived
without further action upon the part of either the Trustee or any Holders of the Securities
of any series; or

     (f) the entry by a court having jurisdiction in the premises of (A) a decree or order
for relief in respect of the Company or any Significant Subsidiary in an involuntary case or

the appointment of or taking possession by a custodian, receiver, liquidator, assignee,
trustee, sequestrator or other similar official of the Company or a Significant Subsidiary
or of any substantial part of the property of the
Company or a Significant Subsidiary, or the making by the Company or a Significant
Subsidiary of an assignment for the benefit of creditors, or the admission by the Company or
a Significant Subsidiary in writing of its inability to pay its debts generally as they
become due, or the taking of corporate action by the Company or a Significant Subsidiary in
furtherance of any such action; or

     (h) any other Event of Default provided with respect to Securities of that series.

26

 

     SECTION 502. Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default with respect to Outstanding Securities of any series occurs and is
continuing (other than an Event of Default specified in Section 501(f) or (g) with respect to the
Company), then and in every such case the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Outstanding Securities of that series may declare the principal amount (or,
if any of the Securities of that series are Original Issue Discount Securities, such lesser portion
of the principal amount of such Securities as may be specified in the terms thereof) of all of the
Securities of that series to be due and payable immediately, by a notice in writing to the Company
(and to the Trustee if given by Holders), and upon any such declaration such principal amount (or
specified portion thereof) shall become immediately due and payable. If an Event of Default
specified in Section 501(f) or (g) with respect to the Company shall occur, then the principal
amount (or, if any of the Securities of that series are Original Issue Discount Securities, such
lesser portion of the principal amount of such Securities as may be specified in the terms thereof)
of all of the Securities shall automatically become immediately due and payable.

     At any time after such a declaration of acceleration with respect to Outstanding Securities of
any series has been made and before a judgment or decree for payment of the money due has been
obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in
aggregate principal amount of the Outstanding Securities of that series, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its consequences if:

     (a) the Company has paid or deposited with the Trustee a sum sufficient to pay

     (1) all overdue interest on all Securities of that series,

     (2) the principal of (and premium, if any, on) any Securities of that series
which have become due otherwise than by such declaration of acceleration and
interest thereon at the rate or rates prescribed therefor in such Securities,

     (3) to the extent that payment of such interest is lawful, interest upon
overdue interest at the rate or rates prescribed therefor in such Securities, and

     (4) all sums paid or advanced by the Trustee hereunder and the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel, and any other amounts due the Trustee under Section 607; and

     (b) all Events of Default with respect to Securities of that series, other than the
non-payment of the principal of Securities of that series which have become due solely by
such declaration of acceleration, have been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

27

 

     SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

     The Company covenants that if

     (a) default is made in the payment of any interest on any Security when such interest
becomes due and payable and such default continues for a period of 30 days, or

     (b) default is made in the payment of the principal of (or premium, if any, on) any
Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such
Security, the whole amount then due and payable on such Security for principal (and premium, if
any) and interest and, to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal (and premium, if any) and on any overdue interest at the rate or
rates prescribed therefor in such Security, and, in addition thereto, such further amount as shall
be sufficient to cover the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

     If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own
name and as trustee of an express trust, may institute a judicial proceeding for the collection of
the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Company or any other obligor upon such Security and collect the moneys
adjudged or decreed to be payable in the manner provided by law out of the property of the Company
or any other obligor upon such Security, wherever situated.

     If an Event of Default with respect to Securities of any series occurs and is continuing, the
Trustee may in its discretion proceed to protect and enforce its rights and the rights of the
Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall
deem most effectual to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein,
or to enforce any other proper remedy.

     SECTION 504. Trustee May File Proofs of Claim.

     In case of the pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the
Company or any other obligor upon the Securities or the property of the Company or of such other
obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or otherwise and irrespective
of whether the Trustee shall have made any demand on the Company for the payment of overdue
principal or interest) shall be entitled and empowered, by intervention in such proceeding or
otherwise,

     (a) to file and prove a claim for the whole amount of principal (and premium, if any)
or such portion of the principal amount of any series of Original Issue Discount Securities
as may be specified in the terms of such series and interest owing and unpaid in respect of
the Securities and to file such other papers or documents as may be necessary or advisable
in order to have the claims of the Trustee (including any claim for

and counsel, and any other amounts due the Trustee under Section 607) and of the Holders

     (b) to collect and receive any moneys or other property payable or deliverable on any
such claims and to distribute the same; and any custodian, receiver, assignee, trustee,

authorized by each Holder to make such 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 counsel, and any other amounts due the Trustee under
Section 607.

     Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any Holder thereof or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

     SECTION 505. Trustee May Enforce Claims Without Possession of Securities.

     All rights of action and claims under this Indenture or the Securities may be prosecuted and
enforced by the Trustee without the possession of any of the Securities or the production thereof
in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be

provision for the payment of the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, and for any other amounts due the Trustee under Section 607,
be for the ratable benefit of the Holders of the Securities in respect of which such judgment has
been recovered.

     SECTION 507. Limitation on Suits.

     No Holder of any Security of any series shall have any right to institute any proceeding,
judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or
trustee, or for any other remedy hereunder, unless

     (a) such Holder has previously given written notice to the Trustee of a continuing
Event of Default with respect to the Securities of that series;

     (b) the Holders of not less than 25% in principal amount of the Outstanding Securities
of that series shall have made written request to the Trustee to institute proceedings in
respect of such Event of Default in its own name as Trustee hereunder;

     (c) such Holder or Holders have offered to the Trustee reasonable indemnity against the
costs, expenses and liabilities to be incurred in compliance with such request;

     (d) the Trustee, for 60 days after its receipt of such notice, request and offer of
indemnity, has failed to institute any such proceeding; and

     (e) no direction inconsistent with such written request has been given to the Trustee
during such 60-day period by the Holders of a majority in principal amount of the
Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have any right in any
manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb
or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such Holders.

     SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and Interest.

     Notwithstanding any other provision in this Indenture, the Holder of any Security shall have
the right, which is absolute and unconditional, to receive payment of the principal of (and
premium, if any) and (subject to Section 307) interest on such Security on the Stated Maturity or
Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and
to institute suit for the enforcement of any such payment, and such rights shall not be impaired
without the consent of such Holder.

     SECTION 509. Restoration of Rights and Remedies.

     If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy
under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has
been determined adversely to the Trustee or to such Holder, then and in every such case, subject to
any determination in such proceeding, the Company, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder and thereafter all rights and
remedies of the Trustee and the Holders shall continue as though no such proceeding had been
instituted.

30

 

     SECTION 510. Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy
herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of
any other right or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

     SECTION 511. Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Securities to exercise any right
or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by
this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

     SECTION 512. Control by Holders.

     The Holders of a majority in aggregate principal amount of the Outstanding Securities of any
series shall have the right to direct the time, method and place of conducting any proceeding for
any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee,
with respect to the Securities of such series, provided that

     (a) such direction shall not be in conflict with any rule of law or with this
Indenture, and

     (b) the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

     SECTION 513. Waiver of Past Defaults.

     The Holders of not less than a majority in aggregate principal amount of the Outstanding
Securities of any series may, on behalf of the Holders of all the Securities of such series, waive
any past default hereunder with respect to such series and its consequences, except a default

     (a) in the payment of the principal of (or premium, if any) or interest on any Security
of such series, or

     (b) in respect of a covenant or provision hereof which under Article Nine cannot be
modified or amended without the consent of the Holder of each Outstanding Security of such
series affected.

     The Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Persons entitled to waive any past default hereunder. If a record date is fixed,
the

31

 

Holders on such record date, or their duly designated proxies, and only such Persons, shall be
entitled to waive any default hereunder, whether or not such Holders remain Holders after such
record date; provided, that unless such majority in principal amount shall have waived such default
prior to the date which is 90 days after such record date, any such waiver of such default
previously given shall automatically and without further action by any Holder be canceled and of no
further effect.

     Upon any such waiver, such default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such
waiver shall extend to any subsequent or other default or impair any right consequent thereon.

     SECTION 514. Undertaking for Costs.

     All parties to this Indenture agree, and each Holder of any Security by such Holder’s
acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, 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, suffered or omitted by it as Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party
litigant in such suit, having due regard to the merits and good faith of the claims or defenses
made by such party litigant; provided, however, that the provisions of this Section shall not apply
to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit
instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the Outstanding Securities of any series, or to any suit instituted by any Holder for the
enforcement of the payment of the principal of (or premium, if any) or interest on any Security on
or after the Stated Maturity or Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date).

     SECTION 515. Waiver of Stay or Extension Laws.

     The Company covenants (to the extent that it may lawfully do so) that it will 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 Company (to the extent that it may lawfully
do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will
not hinder, delay or impede the execution of any power herein granted to the Trustee, but will
suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE SIX

THE TRUSTEE

     SECTION 601. Certain Duties and Responsibilities.

     The provisions of TIA Section 315 shall apply to the Trustee.

32

 

     SECTION 602. Notice of Defaults.

their names and addresses appear in the Security Register, notice of such default hereunder known
to the Trustee, unless such default shall have been cured or waived; provided however, that, except
in the case of a default in the payment of the principal of (or premium, if any) or interest on any
Security of such series or in the payment of any sinking fund installment with respect to
Securities of such series, the Trustee shall be protected in withholding such notice if and so long
as the board of directors, the executive committee or a trust committee of directors and/or
Responsible Officers of the Trustee in good faith determine that the withholding of such notice is
in the interest of the Holders of Securities of such series; and provided, further, that in the
case of any default of the character specified in Section 501(d) with respect to Securities of such
series, no such notice to Holders shall be given until at least 30 days after the occurrence
thereof. For the purpose of this Section, therein “default” means any event which is, or after
notice or lapse of time or both would become, an Event of Default with respect to Securities of
such series.

     Subject to the provisions of TIA Section 315(a) through 315(d):

     (a) the Trustee may rely and shall be protected in acting or refraining from acting
upon any resolution, certificate, statement, instrument, opinion, report, notice, request,
direction, consent, order, bond, debenture, note, other evidence of indebtedness or other
paper or document believed by it to be genuine and to have been signed or presented by the

in the absence of bad faith on its part, rely upon an Officers’ Certificate;

     (d) the Trustee may consult with counsel and the written advice of such counsel or any
Opinion of Counsel shall be full and complete authorization and protection in respect of any
action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

     (e) the Trustee shall be under no obligation to exercise any of the rights or powers
vested in it by this Indenture at the request or direction of any of the Holders pursuant to
this Indenture, unless such Holders shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction;

33

 

     (f) the Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or
other paper or document, but the Trustee, in its discretion, may make such further inquiry
or investigation into such fact or matters as it may see fit, and, if the Trustee shall
determine to make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney;

     (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties
hereunder either directly or by or through agents or attorneys and the Trustee shall not be
responsible for any misconduct or negligence on the part of any agent or attorney appointed
with due care by it hereunder;

     (h) the Trustee shall not be liable for any action taken, suffered or omitted by it in
good faith and believed by it to be authorized or within the discretion, rights or powers
conferred upon it by this Indenture;

     (i) delivery of reports, information and documents to the Trustee under Section 704(a)
and 704(b) is for informational purposes only and the Trustee’s receipt of the foregoing
shall not constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company’s compliance with any
of their covenants hereunder (as to which the Trustee is entitled to rely exclusively on
Officers’ Certificates); and

     (j) except with respect to Section 1001, the Trustee shall have no duty to inquire as
to the performance of the Company with respect to the covenants contained in Article Ten.
In addition, the Trustee shall not be deemed to have knowledge of an Event of Default except
(i) any Event of Default occurring pursuant to Sections 1001, 501(a), 501(b) or 501(c) or
(ii) any Event of Default of which the Trustee shall have received written notification or
obtained actual knowledge.

     SECTION 604. Not Responsible for Recitals or Issuance of Securities.

     The recitals contained herein and in the Securities, except the Trustee’s certificates of
authentication, shall be taken as the statements of the Company, and neither the Trustee nor any
Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the Securities. The
Trustee or any Authenticating Agent shall not be accountable for the use or application by the
Company of Securities or the proceeds thereof.

     SECTION 605. May Hold Securities.

     The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other
agent of the Company, in its individual or any other capacity, may become the owner or pledgee of
Securities and, subject to TIA Sections 310(b) and 311, may otherwise deal with the Company with
the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

34

 

     SECTION 606. Money Held in Trust.

     Money held by the Trustee in trust hereunder need not be segregated from other funds except to
the extent required by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed with the Company.

     SECTION 607. Compensation and Reimbursement.

     The Company agrees

     (a) to pay to the Trustee from time to time reasonable compensation for all services
rendered by it hereunder (which compensation shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust);

     (b) except as otherwise expressly provided herein, to reimburse the Trustee upon its
request for all reasonable expenses, disbursements and advances incurred or made by the
Trustee in accordance with any provision of this Indenture (including the reasonable
compensation and the expenses and disbursements of its agents and counsel), except any such
expense, disbursement or advance as may be attributable to its negligence or bad faith; and

     (c) to indemnify the Trustee and its agents for, and to hold it harmless against, any
loss, liability or expense incurred without negligence or bad faith on its part, arising out
of or in connection with the acceptance or administration of the trust or trusts hereunder,
including the costs and expenses of defending itself against any claim or liability in
connection with the exercise or performance of any of its powers or duties hereunder.

     The obligations of the Company under this Section 607 to compensate and indemnify the Trustee
and to pay or reimburse the Trustee for expenses, disbursements and advances shall constitute
additional indebtedness hereunder and shall survive the satisfaction and discharge of this
Indenture. Such additional indebtedness shall be a senior claim to that of the Securities upon all
property and funds held or collected by the Trustee as such, except funds held in trust for the
payment of principal of (and premium, if any) or interest on particular Securities, and the
Securities are hereby subordinated to each senior claim.

     SECTION 608. Disqualification; Conflicting Interests.

     The provisions of TIA Section 310(b) shall apply to the Trustee.

     SECTION 609. Corporate Trustee Required; Eligibility.

     There shall at all times be a Trustee hereunder which shall be eligible to act under TIA
Section 310(a)(1) and shall have a combined capital and surplus of at least $50,000,000 and subject
to supervision or examination by Federal, State or District of Columbia authority. If such
Corporation publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Corporation shall be deemed to be its combined capital

35

 

and surplus as set forth in its most recent report of condition so published. If at any time the
Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall
resign immediately in the manner and with the effect hereinafter specified in this Article.
Neither the Company, nor any Person directly or indirectly controlling, controlled by or under
common control with the Company, shall act as Trustee hereunder.

     SECTION 610. Resignation and Removal; Appointment of Successor.

     (a) No resignation or removal of the Trustee and no appointment of a successor Trustee
pursuant to this Article shall become effective until the acceptance of appointment by the
successor Trustee in accordance with the applicable requirements of Section 611.

     (b) The Trustee may resign at any time with respect to the Securities of one or more series by
giving written notice thereof to the Company. If the instrument of acceptance by a successor
Trustee required by Section 611 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the Securities of such
series.

     (c) The Trustee may be removed at any time with respect to the Securities of any series by Act
of the Holders of a majority in principal amount of the Outstanding Securities of such series,
delivered to the Trustee and to the Company.

     (d) If at any time:

     (1) the Trustee shall fail to comply with TIA Section 310(b) after written request
therefor by the Company or by any Holder who has been a bona fide Holder of a Security for
at least six months, or

     (2) the Trustee shall cease to be eligible under Section 609 and shall fail to resign
after written request therefor by the Company or by any such Holder, or

     (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or
insolvent or a receiver of the Trustee or of its property shall be appointed or any public
officer shall take charge or control of the Trustee or of its property or affairs for the
purpose of rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the Trustee with respect
to all Securities, or (ii) subject to Section 514, any Holder who has been a bona fide Holder of a
Security for at least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

     (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy
shall occur in the office of Trustee for any cause, with respect to the Securities of one or more
series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees
with respect to the Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of such

36

 

series and that at any time there shall be only one Trustee with respect to the Securities of any
particular series) and shall comply with the applicable requirements of Section 611. If, within
one year after such resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities of such series delivered to
the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment in accordance with the applicable requirements of Section 611,
become the successor Trustee with respect to the Securities of such series and to that extent
supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to
the Securities of any series shall have been so appointed by the Company or the Holders and
accepted appointment in the manner required by Section 611, any Holder who has been a bona fide
Holder of a Security of such series for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the appointment of a
successor Trustee with respect to the Securities of such series.

     (f) The Company shall give notice of each resignation and each removal of the Trustee with
respect to the Securities of any series and each appointment of a successor Trustee with respect to
the Securities of any series by mailing written notice of such event by first-class mail, postage
prepaid, to all Holders of Securities of such series as their names and addresses appear in the
Security Register. Each notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.

     SECTION 611. Acceptance of Appointment by Successor.

     (a) In case of the appointment hereunder of a successor Trustee with respect to all
Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the
Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the rights, powers,
trusts and duties of the retiring Trustee; but, on the request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring
Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder.

     (b) In case of the appointment hereunder of a successor Trustee with respect to the Securities
of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee
with respect to the Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment and which (1)
shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee
with respect to the Securities of that or those series to which the appointment of such successor
Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm that all the rights,
powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those
series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring
Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall be

37

 

necessary to provide for or facilitate the administration of the trusts hereunder by more than one
Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute
such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust
or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other
such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided therein and each such
successor Trustee, without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or
those series to which the appointment of such successor Trustee relates; but, on request of the
Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to
such successor Trustee all property and money held by such retiring Trustee hereunder with respect
to the Securities of that or those series to which the appointment of such successor Trustee
relates. Whenever there is a successor Trustee with respect to one or more (but less than all)
series of securities issued pursuant to this Indenture, the terms “Indenture” and “Securities”
shall have the meanings specified in the provisos to the respective definitions of those terms in
Section 101 which contemplate such situation.

     (c) Upon request of any such successor Trustee, the Company shall execute any and all
instruments for more fully and certainly vesting in and confirming to such successor Trustee all
such rights, powers and trusts referred to in paragraph (a) and (b) of this Section, as the case
may be.

     (d) No successor Trustee shall accept its appointment unless at the time of such acceptance
such successor Trustee shall be qualified and eligible under this Article.

     SECTION 612. Merger, Conversion, Consolidation or Succession to Business.

     Any Corporation into which the Trustee may be merged or converted or with which it may be
consolidated, or any Corporation resulting from any merger, conversion or consolidation to which
the Trustee shall be a party, or any Corporation succeeding to all or substantially all the
corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided
such Corporation shall be otherwise qualified and eligible under this Article, without the
execution or filing of any paper or any further act on the part of any of the parties hereto. In
case any Securities shall have been authenticated, but not delivered, by the Trustee then in
office, any successor by merger, conversion or consolidation to such authenticating Trustee may
adopt such authentication and deliver the Securities so authenticated with the same effect as if
such successor Trustee had itself authenticated such Securities; in case any of the Securities
shall not have been authenticated by the Trustee then in office, any successor by merger,
conversion or consolidation to such Trustee may authenticate such Securities either in the name of
such predecessor hereunder or in the name of the successor 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; provided, however, that the right to adopt
the certificate of authentication of any predecessor Trustee or to authenticate Securities in the
name of any predecessor Trustee shall apply only to its successor or successors by merger,
conversion or consolidation.

38

 

     SECTION 613. Preferential Collection of Claims Against Company.

     The Trustee shall comply with TIA Section 311(a). A Trustee which has resigned or been
removed is subject to TIA Section 311(a) to the extent indicated therein.

     SECTION 614. Appointment of Authenticating Agent.

     At any time when any of the Securities remain Outstanding the Trustee, with the concurrence of
the Company, may appoint an Authenticating Agent or Agents with respect to one or more series of
Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of
such series, and Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder.
Wherever reference is made in this Indenture to the authentication and delivery of Securities by
the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a
certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each
Authenticating Agent shall be acceptable to the Company and shall at all times be a Corporation
organized and doing business under the laws of the United States of America, any State thereof or
the District of Columbia authorized under such laws to act as Authenticating Agent, having a
combined capital and surplus of not less than $50,000,000 and subject to supervision or examination
by Federal, State or District of Columbia authority. If such Authenticating Agent publishes
reports of condition at least annually, pursuant to law or to the requirements of said supervising
or examining authority, then for the purposes of this Section, the combined capital and surplus of
such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time an Authenticating Agent shall
cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent
shall resign immediately in the manner and with the effect specified in this Section.

     Any Corporation into which an Authenticating Agent may be merged or converted or with which it
may be consolidated, or any Corporation resulting from any merger, conversion or consolidation to
which such Authenticating Agent shall be a party, or any Corporation succeeding to the corporate
agency or corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such Corporation shall be otherwise eligible under this Section,
without the execution or filing of any paper or any further act on the part of the Trustee or the
Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee
and to the Company. The Trustee may at anytime terminate the agency of an Authenticating Agent by
giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such

written notice of such appointment by first class mail, postage prepaid, to all Holders of
Securities of the series with respect to which such Authenticating Agent will serve, as their names
and addresses appear in the Security Register. Any successor Authenticating Agent upon acceptance
of its appointment hereunder shall become

39

 

vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed
unless eligible under the provisions of this Section.

     (c) modify any of the provisions of this Section 902, Section 513 or Section 1010,
except to increase any such percentage or to provide that certain other provisions of this

Holders remain Holders after such record date; provided, that unless such consent shall have become

COVENANTS

     SECTION 1001. Payment of Principal, Premium and Interest.

     The Company covenants and agrees for the benefit of each series of Securities that it will
duly and punctually pay the principal of (and premium, if any) and interest on the Securities of
that series in accordance with the terms of the Securities and this Indenture. In the absence of
contrary provisions with respect to the Securities of any series, interest on the Securities of any
series may, at the option of the Company, be paid by check mailed to the address of the Person
entitled thereto as it appears on the Security Register.

     SECTION 1002. Maintenance of Office or Agency.

     The Company will maintain in each Place of Payment for any series of Securities an office or
agency where Securities of that series may be presented or surrendered for payment, where
Securities of that series may be surrendered for registration of transfer or exchange and where
notices and demands to or upon the Company in respect of the Securities of that series and this
Indenture may be served. The Company will give prompt written notice to the Trustee of the
location and any change in the location of such office or agency. If at any time the Company shall
fail to maintain any such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to
receive all such presentations, surrenders, notices and demands.

46

 

     The Company may also from time to time designate one or more other offices or agencies where
the Securities of one or more series may be presented or surrendered for any or all such purposes
and may from time to time rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain an office or
agency in each Place of Payment for Securities of any series for such purposes. The Company will
give prompt written notice to the Trustee of any such designation or rescission and of any change
in the location of any such other office or agency.

     SECTION 1003. Money for Securities Payments to Be Held in Trust.

     If the Company shall at any time act as its own Paying Agent with respect to any series of
Securities, it will, on or before each due date of the principal of (and premium, if any) or
interest on any of the Securities of that series, segregate and hold in trust for the benefit of
the Persons entitled thereto a sum in the currency in which such series of Securities is payable
sufficient to pay the principal (and premium, if any) or interest so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify
the Trustee of its failure so to act.

     Whenever the Company shall have one or more Paying Agents for any series of Securities, it
will, prior to each due date of the principal of (and premium, if any) or interest on any
Securities of that series, deposit with a Paying Agent a sum sufficient to pay the principal (and
premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of its failure so to act.

     The Company will cause each Paying Agent for any series of Securities other than the Trustee
to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the
Trustee, subject to the provisions of this Section, that such Paying Agent will:

     (a) hold all sums held by it for the payment of the principal of (and premium, if any)
or interest on Securities of that series in trust for the benefit of the Persons entitled
thereto until such sums shall be paid to such Persons or otherwise disposed of as herein
provided;

     (b) give the Trustee notice of any default by the Company (or any other obligor upon
the Securities of that series) in the making of any payment of principal (and premium, if
any) or interest on the Securities of that series; and

     (c) at any time during the continuance of any such default, upon the written request of
the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

     The Company may at any time, for the purpose of obtaining the satisfaction and discharge of
this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay,
to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by
the Trustee upon the same trusts as those upon which such sums were held by the Company or such
Paying Agent, and, upon such payment by any Paying Agent to the

47

 

Trustee, such Paying Agent shall be released from all further liability with respect to such money.

     Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of (and premium, if any) or interest on any Security of any
series and remaining unclaimed for two years after such principal (and premium, if any) or interest
has become due and payable shall be paid to the Company on Company Request, or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as
an unsecured general creditor, look only to the Company for payment thereof, and all liability of
the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company
as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying
Agent, before being required to make any such repayment, may at the expense of the Company cause to
be published once, in a newspaper published in the English language, customarily published on each
Business Day and of general circulation in the Borough of Manhattan, The City of New York, notice
that such money remains unclaimed and that, after a date specified therein, which shall not be less
than 30 days from the date of such publication, any unclaimed balance of such money then remaining
will be repaid to the Company on Company Request.

     SECTION 1004. Existence.

     Subject to Article Eight, the Company will do or cause to be done all things necessary to
preserve and keep in full force and effect its existence, rights (charter and statutory) and
franchises; provided, however, that the Company shall not be required to preserve any such right or
franchise if the Board of Directors shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and that the loss thereof is not
disadvantageous in any material respect to the Holders.

     SECTION 1005. Maintenance of Properties.

     The Company will cause all properties used or useful in the conduct of its business to be
maintained and kept in good condition, repair and working order and supplied with all necessary
equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and
improvements thereof, all as in the judgment of the Company may be necessary so that the business
carried on in connection therewith may be properly and advantageously conducted at all times;
provided, however, that nothing in this Section shall prevent the Company from discontinuing the
operation or maintenance of any of such properties if such discontinuance is, in the judgment of
the Company, desirable in the conduct of its business and not disadvantageous in any material
respect to the Holders.

     SECTION 1006. Payment of Taxes and Other Claims.

     The Company will pay or discharge or cause to be paid or discharged, before the same shall
become delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon it or
upon its income, profits or property, and (2) all lawful claims for labor, materials and supplies
which, if unpaid, might by law become a lien upon its property; provided, however, that the Company
shall not be required to pay or discharge or cause to be paid or discharged any such

48

 

tax, assessment, charge or claim whose amount, applicability or validity is being contested in good
faith.

     SECTION 1007. Restriction on Secured Debt.

     (a) The Company will not itself, and will not permit any Subsidiary to, incur, issue, assume
or guarantee any notes, bonds, debentures or other similar evidences of indebtedness for money
borrowed (notes, bonds, debentures or other similar evidences of indebtedness for money borrowed
being hereinafter in this Article called “Debt”), secured by pledge of, or mortgage or other lien
on, any Property, now owned or hereafter owned by the Company or any Subsidiary, or any shares of
stock or Debt of any Subsidiary (pledges, mortgages and other liens being hereinafter in this
Article called “Lien” or “Liens”), without effectively providing that the Securities of each series
then Outstanding (together with, if the Company shall so determine, any other Debt of the Company
or such Subsidiary then existing or thereafter created which is not subordinate to the Securities
of each series then Outstanding) shall be secured equally and ratably with (or prior to) such
secured Debt, so long as such secured Debt shall be so secured; provided, however, that this
Section shall not apply to, and there shall be excluded from secured Debt in any computation under
this Section, Debt secured by:

     (1) Liens on any Property acquired, constructed or improved by the Company or any
Subsidiary after the date of this Indenture which are created or assumed contemporaneously
with such acquisition, construction or improvement, or within 180 days before or after the
completion thereof, to secure or provide for the payment of all or any part of the cost of
such acquisition, construction or improvement;

     (2) Liens of or upon any property, shares of capital stock or Debt existing at the time
of acquisition thereof, whether by merger, consolidation, purchase, lease or otherwise
(including Liens of or upon property, shares of capital stock or indebtedness of a
Corporation existing at the time such Corporation becomes a Subsidiary);

     (3) Liens in favor of the Company or any Subsidiary;

     (4) Liens in favor of the United States of America or any State thereof, or any
department, agency or instrumentality or political subdivision of the United States of
America or any State thereof or political entity affiliated therewith, or in favor of any

other payments, or other obligations, pursuant to any contract or statute;

     (5) Liens imposed by law, such as mechanics’, workmen’s, repairmen’s, materialmen’s,

business;

     (6) pledges or deposits under workmen’s compensation laws or similar legislation and
Liens of judgments thereunder which are not currently dischargeable, or good faith deposits
in connection with bids, tenders, contracts (other than for the payment of money) or leases
to which the Company or any Subsidiary is a party, or deposits to secure public or statutory
obligations of the Company or any Subsidiary, or deposits in connection with obtaining or
maintaining self- insurance or to obtain the benefits of any

49

 

law, regulation or arrangement pertaining to unemployment insurance, old age pensions,
social security or similar matters, or deposits of cash or obligations of the United States
of America to secure surety, appeal or customs bonds to which the Company or any Subsidiary
is a party, or deposits in litigation or other proceedings such as, but not limited to,
interpleader proceedings;

     (7) Liens created by or resulting from any litigation or other proceeding which is
being contested in good faith by appropriate proceedings, including Liens arising out of
judgments or awards against the Company or any Subsidiary with respect to which the Company
or such Subsidiary is in good faith prosecuting an appeal or proceedings for review; or

discharge in the course of any litigation or other proceeding to which the Company or such
Subsidiary is a party;

     (8) Liens for taxes or assessments or governmental charges or levies not yet due or
delinquent, or which can thereafter be paid without penalty, or which are being contested in
good faith by appropriate proceedings;

     (9) Liens consisting of easements, rights-of-way, zoning restrictions, restrictions on
the use of real property, and defects and irregularities in the title thereto, landlords’
liens and other similar liens and encumbrances none of which interfere materially with the
use of the property covered thereby in the ordinary course of the business of the Company or
such Subsidiary and which do not, in the opinion of the Company, materially detract from the
value of such properties; or

     (10) any extension, renewal or replacement (or successive extensions, renewals or
replacements), as a whole or in part, of any Lien referred to in the foregoing clauses (1)
to (9), inclusive; provided, that (i) such extension, renewal or replacement Lien shall be
limited to all or a part of the same property, shares of stock or Debt that secured the Lien
extended, renewed or replaced (plus improvements on such property) and (ii) the Debt secured
by such Lien at such time is not increased.

     (b) Notwithstanding the restrictions contained in Section 1007(a) of this Section, the Company
and its Subsidiaries, or any of them, may incur, issue, assume or guarantee Debt secured by Liens
without equally and ratably securing the Securities of each series then Outstanding, provided, that

the Company or a Subsidiary for a period, including renewals, in excess of three years of any
Principal Property which has been or is to be sold or transferred by the Company or any Subsidiary
to such lender or investor or to any Person to whom funds have been or are to be advanced by such
lender or investor on the security of such Principal Property (herein referred to as a “Sale and
Leaseback Transaction”) unless the Company within 180 days after the sale or transfer shall have
been made by the Company or by a Subsidiary, applies an amount equal to the greater of (i) the net
proceeds of the sale of the Principal Property sold and leased back pursuant to such arrangement or
(ii) the fair market value of the Principal Property so sold and leased back at the time of
entering into such arrangement (as determined by any two of the following: the Chairman or a Vice
Chairman of the Board of the Company, its President, its Chief Financial Officer, its Vice
President of Finance, its Treasurer or its Controller) to the retirement of Funded Debt of the
Company; provided, that the amount to be applied to the retirement of Funded Debt of the Company
shall be reduced by (A) the principal amount of any Securities delivered within 120 days after such
sale to the Trustee for retirement and cancellation, and (B) the principal amount of Funded Debt,
other than Securities, voluntarily retired by the Company within 120 days after such sale.
Notwithstanding the foregoing, no retirement referred to in this Section 1008(a) may be effected by
payment at maturity or pursuant to any mandatory sinking fund payment or mandatory prepayment
provision.

     (b) Notwithstanding the restrictions contained in Section 1008(a), the Company and its
Subsidiaries, or any of them, may enter into a Sale and Leaseback Transaction, provided, that at
the time of such transaction, after giving effect thereto, the aggregate amount of all Attributable
Debt in respect of Sale and Leaseback Transactions existing at such time which could not have been
entered into except for the provisions of this Section 1008(b) plus the aggregate amount of Debt
secured by Liens (other than Debt secured by Liens pursuant to paragraphs (1) through (10),
inclusive, of Section 1007(a)) does not at such time exceed 10% of Consolidated Net Tangible Assets
of the Company.

     (c) A Sale and Leaseback Transaction shall not be deemed to result in the creation of a Lien.

     SECTION 1009. Defeasance of Certain Obligations.

     The following provisions shall apply to the Securities of each series unless specifically
otherwise provided in a Board Resolution, Officers’ Certificate or indenture supplemental hereto
provided pursuant to Section 301. The Company may omit to comply with any term, provision or
condition set forth in Sections 1005, 1006, 1007 and 1008 and any such omission with respect to
Sections 1005, 1006, 1007 and 1008 shall not be an Event of Default, in each case with respect to
the Securities of that series, provided that the following conditions have been satisfied:

     (a) with reference to this Section 1009, the Company has deposited or caused to be
irrevocably deposited with the Trustee (or another trustee satisfying the

51

 

requirements of Section 609) as trust funds in trust, specifically pledged as security for,
and dedicated solely to, the benefit of the Holders of the Securities of that series, (i)
money in an amount, or (ii) U.S. Government Obligations which through the payment of
interest and principal in respect thereof in accordance with their terms will provide not
later than one day before the due date of any payment referred to in clause (iii)(A) or (B)
of this subparagraph (a) money in an amount, or (iii) a combination thereof, sufficient, in
the opinion of a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge (A) the
principal of (and premium, if any) and each installment of principal (and premium, if any)
and interest on the Outstanding Securities on the Stated Maturity of such principal or
installments of principal and interest and (B) any mandatory sinking fund payments or
analogous payments applicable to the Securities of such series on the day on which such
payments are due and payable in accordance with the terms of this Indenture and of such
Securities;

     (b) such deposit shall not cause the Trustee with respect to the Securities of that
series to have a conflicting interest as defined in Section 608 and for purposes of the
Trust Indenture Act with respect to the Securities of any series;

     (c) such deposit will not result in a breach or violation of, or constitute a default
under, this Indenture or any other agreement or instrument to which the Company is a party
or by which it is bound;

     (d) no Event of Default or event which with notice or lapse of time would become an
Event of Default with respect to the Securities of that series shall have occurred and be
continuing on the date of such deposit;

     (e) the Company has delivered to the Trustee an Opinion of Counsel to the effect that
Holders of the Securities of such series will not recognize income, gain or loss for Federal
income tax purposes as a result of such deposit and defeasance of certain obligations and
will be subject to Federal income tax on the same amount and in the same manner and at the
same times as would have been the case if such deposit and defeasance had not occurred; and

     (f) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that all conditions precedent herein provided for relating to the
defeasance contemplated in this Section have been complied with.

     SECTION 1010. Waiver of Certain Covenants.

     The Company may omit in any particular instance to comply with any term, provision or
condition set forth in Sections 1004 to 1008, inclusive, with respect to the Securities of any
series if before the time for such compliance the Holders of not less than a majority in aggregate
principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such term, provision or
condition, but no such waiver shall extend to or affect such term, provision or condition except to
the extent so expressly waived, and, until such waiver shall become effective,

52

 

the obligations of the Company and the duties of the Trustee in respect of any such term, provision
or condition shall remain in full force and effect.

     The Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Persons entitled to waive any such term, provision or condition. If a record date
is fixed for such purpose, the Holders on such record date or their duly designated proxies, and
only such Persons, shall be entitled to waive any such term, provision or condition hereunder,
whether or not such Holders remain Holders after such record date; provided that unless the Holders
of not less than a majority in principal amount of the Outstanding Securities of such series shall
have waived such term, provision or condition prior to the date which is 90 days after such record
date, any such waiver previously given shall automatically and without further action by any Holder
be canceled and of no further effect.

ARTICLE ELEVEN

REDEMPTION OF SECURITIES

     SECTION 1101. Applicability of Article.

     Securities of any series which are redeemable before their Stated Maturity shall be redeemable
in accordance with their terms and (except as otherwise specified as contemplated by Section 301
for Securities of any series) in accordance with this Article.

     SECTION 1102. Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by an Officers’
Certificate. The Company shall, at least 45 days prior to the Redemption Date fixed by the Company
(unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of

     (a) such Redemption Date,

     (b) if the Securities of such series have different terms and less than all of the
Securities of such series are to be redeemed, the terms of the Securities to be redeemed,
and

     (c) if less than all the Securities of such series with identical terms are to be
redeemed, the principal amount of such Securities to be redeemed.

In the case of any redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company
shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such
restriction.

     SECTION 1103. Selection by Trustee of Securities to Be Redeemed.

     If less than all the Securities of like tenor of any series are to be redeemed, the particular
Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by
the Trustee, from the Outstanding Securities of like tenor of such series not previously called for
redemption, by such method as the Trustee shall deem fair and appropriate and which may

53

 

provide for the selection for redemption of portions (equal to the minimum authorized denomination
for Securities of like tenor of that series or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum authorized
denomination for Securities of that series.

     The Trustee shall promptly notify the Company in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption, the principal amount
thereof to be redeemed.

     For all purposes of this Indenture, unless the context otherwise requires, all provisions
relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to
be redeemed only in part, to the portion of the principal amount of such Securities which has been
or is to be redeemed.

     SECTION 1104. Notice of Redemption.

     Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than
30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed,
at each such Holder’s address appearing in the Security Register.

     All notices of redemption shall state:

     (a) the Redemption Date,

     (b) the Redemption Price,

     (c) if less than all the Outstanding Securities of like tenor of any series are to be
redeemed, the identification (and, in the case of partial redemption, the principal amounts)
of the particular Securities to be redeemed,

     (d) that on the Redemption Date the Redemption Price will become due and payable upon
each such Security to be redeemed and, if applicable, that interest thereon will cease to
accrue on and after said date,

     (e) the place or places where such Securities are to be surrendered for payment of the
Redemption Price, and

     (f) that the redemption is for a sinking fund, if such is the case.

     Notice of redemption of Securities to be redeemed at the election of the Company shall be
given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of
the Company.

     SECTION 1105. Deposit of Redemption Price.

     On or prior to any Redemption Date, the Company shall deposit with the Trustee or with a
Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 1003) an amount of money in immediately available funds sufficient to

54

 

pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date)
accrued interest on, all the Securities which are to be redeemed on that date.

     SECTION 1106. Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall,
on the Redemption Date, become due and payable at the Redemption Price therein specified, and from
and after such date (unless the Company shall default in the payment of the Redemption Price and
accrued interest) such Securities shall cease to bear interest. Upon surrender of any such
Security for redemption in accordance with said notice, such Security shall be paid by the Company
at the Redemption Price, together with accrued interest to the Redemption Date; provided, however,
that, unless otherwise specified as contemplated by Section 301, installments of interest whose
Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the close of business on
the relevant Regular Record Dates according to their terms and the provisions of Section 307.

     If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal (and premium, if any) shall, until paid, bear interest from the
Redemption Date at the rate prescribed therefor in the Security.

     SECTION 1107. Securities Redeemed in Part.

     Any Security which is to be redeemed in part shall be surrendered at a Place of Payment for
such series (with, if the Company or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the
Holder thereof or such Holder’s attorney duly authorized in writing), and the Company shall
execute, and the Trustee shall authenticate and deliver to the Holder of such Security without
service charge, a new Security or Securities of the same series and of like tenor, of any
authorized denomination as requested by such Holder, in aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the Security so surrendered; provided,
however, that if a Global Security is so surrendered, such new Security so issued shall be a new
Global Security in a denomination equal to the unredeemed portion of the principal of the Global
Security so surrendered.

ARTICLE TWELVE

SINKING FUNDS

     SECTION 1201. Applicability of Article.

     To the extent that the provisions of this Article shall be applicable to the Securities of a
series as specified pursuant to Section 301, the provisions of this Article shall be applicable to
any sinking fund for the retirement of Securities of such series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

     The minimum amount of any sinking fund payment provided for by the terms of Securities of any
series is herein referred to as a “mandatory sinking fund payment”, and any payment in excess of
such minimum amount provided for by the terms of Securities of any series

55

 

is herein referred to as an “optional sinking fund payment”. If provided for by the terms of
Securities of any series, the cash amount of any sinking fund payment may be subject to reduction
as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of
Securities of any series as provided for by the terms of Securities of such series.

     SECTION 1202. Satisfaction of Sinking Fund Payments with Securities.

     The Company (1) may deliver Outstanding Securities of like tenor of a series (other than any
previously called for redemption) and (2) may apply as a credit Securities of like tenor of a
series which have been redeemed either at the election of the Company pursuant to the terms of such
Securities or through the application of permitted optional sinking fund payments pursuant to the
terms of such Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of like tenor of such series required to be made pursuant to
the terms of such Securities as provided for by the terms of such series; provided that such
Securities have not been previously so credited. Such Securities shall be received and credited
for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.

     SECTION 1203. Redemption of Securities for Sinking Fund.

     Not less than 60 days prior to each sinking fund payment date for Securities of like tenor of
a series, the Company will deliver to the Trustee an Officers’ Certificate specifying the amount of
the next ensuing sinking fund payment for such Securities pursuant to the terms of such Securities,
the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof,
if any, which is to be satisfied by delivering and crediting Securities of like tenor of that
series pursuant to Section 1202 and, at the time of delivery of such Officers’ Certificate, will
also deliver to the Trustee any Securities to be so delivered. Not less than 45 days before each
such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such
sinking fund payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company in the manner
provided in Section 1104. Such notice having been duly given, the redemption of such Securities
shall be made upon the terms and in the manner stated in Sections 1106 and 1107.

56

 

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

     IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed as of
the day and year first above written.

EXECUTIVE SUMMARY

This Revised Final Proposal (Final Proposal) submitted by Ameresco Federal Solutions, Inc.
(Ameresco) is for the implementation of two biomass Energy Conservation Measures (ECMs) at the
Department of Energy’s (DOE) Savannah River Site (SRS), located in South Carolina, approximately 18
miles south of Aiken and 20 miles east of Augusta, Georgia. The ECMs are being proposed under the
authority and terms of the DOE Biomass and Alternate Methane Fuel (BAMF) Energy Savings Performance
Contract number DE-AM36-02-NT41457 as modified by DO RFP # DE-RP09-09SR22572, dated February 26,
2009. This Revised Final Proposal including technical, pricing, and management data shall remain
valid through June 15, 2009.

The proposal consists of two Energy Conservation Measures (ECMs). ECM 1 provides for the turnkey
installation of a new Biomass Cogeneration Facility with a design capacity of 240,000 pounds per
hour (PPH) of steam and 20 megawatts (MW) of electric power. The new facility will replace the
existing D Area coal-fired cogeneration plant. ECM 2 includes the turnkey installation of two 10,500 PPH
steam heating facilities; one to be located in the K Area and one to be located in the L Area.
These systems will replace the aging fuel oil-fired packaged boilers currently serving the K and L
Areas of the site.

The existing D Area cogeneration plant produces both steam and electricity that is consumed on
site. The steam is delivered through a large distribution pipeline that runs several miles from
the plant to the end-user facilities. The plant also produces approximately 15 MW of electricity
that is consumed by DOE facilities on site. The 1950s era plant is fueled by coal and in need of
significant modifications to bring the plant into compliance with current environmental
requirements as well as to be a reliable source of energy. The proposed Biomass Cogeneration
Facility, sited near the existing steam interconnection at the intersection of Burma Road and C
Road, will significantly reduce the distance from the plant to the end-user, resulting in improved
operating efficiency. The new facility will have enough capacity to satisfy all of the site’s
steam requirements and a significant portion of the electrical demand which will allow for the D
Area plant to be shut down.

Currently, the existing heating plant in the K Area provides steam for both the K and L Areas.
Steam is delivered from the K Area plant to L Area facilities through a 6”, 2.5 mile pipeline. ECM
2 provides for replacing the K Area plant with two 10,500 PPH boilers — one boiler located in K
Area and one located in L Area — eliminating the need to use the 2.5 mile distribution line. The
existing K Area plant and the steam line will be shut down.

Clean biomass and bio-derived fuels (BDF) will be the primary fuel source for all of the new
boilers. The clean biomass consists of various types of forest residues, and the BDF consists
primarily of scrapped vehicle tires. Fuel deliveries will be received by Ameresco staff at a fuel handling yard located
within the Biomass Cogeneration Facility site at the Burma Road/C Road location. The fuel handling
yard includes a fuel receiving, storage, and processing area that will serve the Biomass
Cogeneration Facility and the K and L Area Heating Plants. Fuel deliveries to the K and L Area
Heating Plants will be made by Ameresco staff on an as-needed basis from the central fuel yard.

The use of renewable energy fuel sources provides many positive economic and environmental
benefits to the SRS and the local community, while providing significant energy and cost savings to
SRS. The savings result from fuel switching (coal to biomass), reductions in line losses by
locating the new cogeneration facility and heating plants closer to end-user facilities, and
improved efficiencies from new equipment sized to better match existing load requirements. Key
environmental benefits of the project include:

	 	•	 	Over 2,000,000 MBtu/yr of thermal renewable energy production and a minimum
generation of 77,000 mWh (264,444 MBtu) of green power.
	 
	 	•	 	Annual Energy Savings of approximately 500,000 MBtu/yr
	 
	 	•	 	No-cost Renewable Energy Credits (RECs)
	 
	 	•	 	Decrease of water intake from the Savannah River by 1,412,000
kgal/yr, supporting water conservation efforts in the regional drought situation.
	 
	 	•	 	Reduction of 400 tons/yr of Particulate Matter (PM) emissions
	 
	 	•	 	Reduction of 3,500 tons/yr of Sulfur Dioxide (SO2) emissions
	 
	 	•	 	Reduction of 100,000 tons/yr of Carbon Dioxide (CO2) emissions
	 
	 	•	 	Support of the South Carolina Biomass Council Goals

Ameresco proposes to provide a turnkey package of design, permitting, and installation. Ameresco
will also take responsibility for the operation and maintenance of the cogeneration facility and
heating plants throughout the contract term. Table ES.1 below provides an overview of project
economics (as shown on Schedule DO-4) for Performance Period Year 1.

Following contract award, the detailed design will be completed and construction of the new
facilities will take place. It is expected that thirty months from the date of contract award will
be required to complete the final design and construction of the main Biomass Cogeneration
Facility. However, Ameresco expects that the K and L Area Heating Plants can be constructed within
18 months of contract award. For this reason, Ameresco proposes an early acceptance of ECM 2.

1.1 ECM Summary Schedule DO-4

Pricing Schedule DO-4 is included in Section 6.0, Proposal Pricing Information.

1.2 ECM #1:Biomass Cogeneration Facility 

1.2.1 Detailed Description of ECM

1.2.1.1 ECM Summary

This ECM comprises the design and construction of a Biomass Cogeneration Facility
(cogeneration facility) to be located to the northwest of the main distribution steam
interconnection at the intersection of Burma Road and C Road. The steam produced from the facility
will be exported to the 200 Areas via the existing distribution system; the green power generated
will be exported to the SRS electrical distribution system via a new interconnection at the
existing F Area substation. The scope of work includes the installation of the cogeneration
facility and all equipment, the site work, and the necessary utility interconnections required for
plant operation. There are three additional items included in the scope (design drawings for these
items to be provided following contract award):

	 	1)	 	The procurement and installation of a new skid-mounted river water pump and new pumping
systems controls at the river water pump house, Building 681-3G.
	 
	 	2)	 	Rework of the electrical feeder from the TNX area to the South Carolina Electric and
Gas (SCE&G) utility line at the D Area.
	 
	 	3)	 	Relocation of the existing L Area capacitor bank.

The cogeneration facility will be sized to provide a continuous supply of steam to site end-users
(based on current and future load projections as presented in the SRS Site Projection Profile
provided by the Government) while optimizing the quantity of green power generated. The system is
designed using applicable national codes and standards for power plants and specific site standards
(refer to Section 5.2). Previously, conceptual design drawings were submitted to the site for
review prior to issuance of this final proposal; a draft version of the “issued for pricing”
drawings is included in Volume III of this proposal. Finalized “issued for construction” drawings
will be submitted to the government for concurrence throughout the first year of the construction
period, as major equipment items are ordered and the design drawings are finalized.

This ECM will provide an estimated savings of over $33 million in the first year of operation
through the offset of coal purchases, and reduced O&M from the elimination of the existing D Area
Power Plant and electrical substation. The renewable energy-fueled cogeneration facility will also
provide renewable energy credits (RECs) to SRS at no cost. For purposes of receiving credit for
implementing this renewable energy initiative, the RECs attached to ECM 1 and ECM 2 will belong to the Government and
will not be claimed nor sold by Ameresco.

In addition to the design and construction, Ameresco will retain responsibility for fuel
delivery, operations, maintenance of the cogeneration facility and site; repair and replacement of
the cogeneration facility equipment; air and effluent outfall emissions compliance for the
cogeneration facility; and monitoring, measurement, and verification (M&V) throughout the contract
term. Refer to Section 5.2.7 for details on Ameresco’s Site Operations.

1.2.1.2 ECM Design Process

The proposed cogeneration facility will provide steam and power to the SRS site. Several
configurations and energy models were analyzed during the Detailed Energy Survey (DES) phase to
determine the final system sizing and system components. The optimal equipment selection and
sizing was selected to balance the current and future thermal needs of the site while maximizing
green power generation. Final selection resulted in a system composed of two (2) biomass bubbling
fluidized bed boilers, each with an output capacity of 120,000 PPH (240,000 PPH plant total) steam
and one (1) condensing steam turbine/generator with an output design capacity of 20 MW.

Superheated steam will be produced in the new combustor/boiler systems at 850 pounds per square
inch gauge (psig) and 825 degrees Fahrenheit (°F), for delivery to the turbine/generator
unit. Steam is extracted at a reduced pressure (385 psig nominal) from the turbine to meet the
demand of the site, as well as for parasitic use. As the primary purpose of the cogeneration
facility is to provide a continuous supply of steam, the amount of steam extracted from the turbine
will vary to meet the site demand. As the extraction rate varies with the site steam demand, the
gross power output from the turbine/generator will also vary. Based on future steam load forecasts
as presented in the SRS Site Projection Profile provided by the Government (Table 1.1 below),
output from the turbine/generator will range from 8 to 20 MW. The net power exported will vary
from 5 to 17 MW as the new cogeneration facility’s in-house (parasitic) loads will range between
2-4 MW. A detailed basis of design is included in the following subsections.

Site

The location of the new cogeneration facility was selected during the initial feasibility study of
the project. The facility will be located approximately 0.5 miles northwest of the intersection of
Burma and C Roads on a 30 acre site. The development on the site will include the following major
areas: 1) the fuel handling yard, 2) the boiler/combustion system, 3) the power plant, 4) the
cooling tower and outfall piping, and 5) the administration building and site parking. The
placement of the cogeneration facility on this site was optimized to minimize fuel handling
conveyor runs, and to ensure critical systems are located near the operator control room. The
layout was also arranged to make use of the natural topography of the land where possible to
minimize disturbance to the environment. The location and layout of the facilities were also
optimized to the extent possible with regard to interfaces with site utilities (described in
Section 1.2.3), a new storm water collection system and outfall, and the new site fire protection
system.

The storm water system is designed to collect storm water from the impervious portions of the site.
These include building run-off, roadway run-off, and equipment run-off. The system will include a
series of

catch basins to collect the storm water. The site will be graded to direct the storm water to
each of the catch basins. The catch basins will be interconnected by 6”, 8”, and 12” piping. A
manhole will be included to provide maintenance access at each change of direction. Ultimately the
storm water will be directed by gravity to a storm water detention pond which is sized to hold the
expected rainfall peaks in the area. The pond will be complete with a liner and slotted spillway
to enable a controlled release of water to the outfall. The system will be installed with a
monitoring system to measure flow, pH, and conductivity. Major components include catch basins,
piping, manholes for maintenance access, lined 165,000 gallon detention pond, monitoring system,
and the 24” outfall.

Extensive soil testing was completed on the site to determine the conditions for the soil and
recommended design for structural support of equipment, facilities, and new pavements. The soil
composition is primarily sand with light clay and therefore requires treatment of the site with an
engineered fill prior to foundation work. A copy of the complete soil report is included in
Appendix A of this proposal.

Logistics of site traffic are designed to allow biomass delivery trucks and other facility traffic
to enter the site from Burma Road. The existing gravel portion of Burma Road will be paved up to
the entrance of the site. Delivery trucks will enter the facility from the Burma Road entrance
using a new deceleration lane, and exit the facility via a new one-way exit along the former route
of Old Burma Road (currently an unmaintained dirt pathway between Burma and C Roads). All other
facility traffic will enter into the new parking lot or the on-site access road, and may then exit
back to Burma Road or use the new one-way exit to C Road.

Delivery trucks will traverse the entrance road to the fuel yard, and after fuel delivery will exit
via Old Burma Road, which will be re-cleared and paved up to C Road at the existing 3-way
intersection of C Road and the entry to the F Area. Old Burma Road will be designated and marked
as a one-way thoroughfare in accordance with South Carolina Department of Transportation (SCDOT)
standards, and the traffic signal at the existing 3-way intersection on C Road will be converted to
a new 4-way intersection. This arrangement provides for a safe traffic flow and allows delivery
vehicles to make left-hand turns across traffic only at a signal-controlled intersection. Also
included in the site scope of work is the removal of the curbed median at the existing 3-way
intersection, and the installation of new loop-control vehicle sensor wiring beneath the pavement
at the new 4-way intersection. Figure 1.1 is an illustration of the overall site layout; the
specific areas within the site are further described in the following pages.

Fuel Handling Yard

The fuel handling yard will serve as the delivery point for all fuel supplies for the cogeneration
facility, as well as the two heating plants serving the K and L Areas. Approximately 40-60 trucks
will enter the site daily (at staggered delivery times) at the Burma Road facility entrance. The
entrance to the yard will include truck scales for weigh-in of all fuel sources for tracking
deliveries. Beyond the entrance will be the unloading equipment, fuel storage area, and the fuel
handling and processing equipment.

For fuel handling operations at the cogeneration facility, front-end loaders and augers/conveyors
will be used at various points in the yard to move fuel between stations, through the yard area,
and into the combustion systems. The biomass wood fuel will be unloaded using three (3) automated
hydraulic truck-dumping stations. The truck-dumpers discharge into a reclaim pit, where the fuel
will be lifted to the first transfer conveyor. The fuel is then screened and processed through a
hogger and disc screen onto a second transfer conveyor. The fuel can then be transferred into the
outside storage area or directly into the metering bins of the combustors. Stored fuel will be
stacked in the outside storage after delivery from the transfer conveyor by use of a circular
stacker/reclaimer. In addition to stacking the fuel, the stacker/reclaimer functions as a
reclaimer to transfer the fuel from the storage stack to the fuel metering bins prior to entering
the combustors.

The total available outside storage for clean biomass is approximately 15 acres, allowing for 30
days of continuous operations without replenishing the on-site fuel storage. The scrap vehicle
tires brought to the site will be unloaded and processed in a separate area before being augured
into a separate reclaimer. The separate unloading area and reclaimer allow for better process
control through mixing with the biomass fuel, and also help to quantify BDF usage in meeting the
requirements of the South Carolina Department of Health and Environmental Control (SCDHEC) air
permit with regards to limits on BDF combustion.

Fuel supplies for the K and L Area boilers will be loaded at the cogeneration facility fuel
handling yard and trucked by Ameresco staff to the K and L Area heating plants as needed, since the
heating plants operate only during a limited heating season. One truckload per day is the
estimated maximum usage at both the K and L Area heating plants during the coldest periods.

Proposed Fuel Yard Components include:

	 	•	 	Two (2) Truck scales
	 
	 	•	 	Three (3) Hydraulic truck dumps and reclaimers
	 
	 	•	 	Front end loaders
	 
	 	•	 	Dump trucks for site use
	 
	 	•	 	Live bottom trailers for K and L Area
	 
	 	•	 	One (1) Fuel hogger
	 
	 	•	 	One (1) Screener for oversized product
	 
	 	•	 	Two (2) Magnets for metals screening
	 
	 	•	 	One (1) Stacker & Reclaimer
	 
	 	•	 	One (1) Truck Reclaim for Tires

The final design of the system was developed with primary consideration given to the
following: handling and processing of multiple fuel types; safe and plentiful fuel storage area on
site; minimized maintenance requirements; reduced downtimes; and provision for flexible operation
of the overall systems.

Combustion/Boiler System

The combustion/boiler system includes the components from the fuel feeders to the exhaust stack,
including the boiler auxiliaries. A bubbling fluidized bed (BFB) combustion technology will be
used for this project. BFB technology uses high pressure air to fluidize a 2-3 foot bed of sand
(inert material) in suspension. The fuel source is fed into the system through air spouts and
mixed into the suspended bed. The system operates using 30-40% theoretical combustion air to
reduce bed temperature and minimize nitrogen oxide (NOx) emissions.

BFB technology is preferable for biomass fuels due to its ability to better tolerate various fuel
types, as well as larger variations in both fuel mixture density and moisture content. BFBs have
the advantage of reduced air emissions due to a more stringently controlled temperature in the
combustion process (1400-1600oF). Compared to stoker technology, the bubbling bed
offers lower uncontrolled air emission rates, resulting in a lower investment for downstream air
pollution control system components. BFBs require less maintenance than the stoker boiler,
resulting in less downtime and lower ongoing costs.

benefits in this size range of BFB equipment:

Figure 1.2: EPI Fluidized Bed Energy System

Two identical BFBs will be installed in the new cogeneration facility. Both boilers will be sized
for a total design input of 372 MBtu/hr (186 MBtu/hr per boiler) and an output of 240 kpph (120
kpph per boiler). The bubbling bed boiler will produce steam at 850 psig, 825°F. Steam
generated will go through a condensing turbine when generating electricity, or through a pressure
reducing valve (PRV) station which will reduce the pressure to 385 psig. Steam required by the
site and for the cogeneration facility deaerator (DA) tank will be extracted from the turbine at
385 psig. The 385 psig steam will be distributed to the existing system via the interconnection to
the existing steam header located just across the street from the new cogeneration facility.
Additionally, full capacity fuel oil burners will also be installed in the combustor to serve as a
back up fuel source in case the biomass feeders are down. Refer to Section 1.2.1.3 for details of
SRS steam demand.

Figure 1.3: EPI Fluidized Bed Cell

Fuel will enter into the combustion metering bins from the fuel transfer conveyors. Metered fuel
is discharged through isolation slide gates and into the fuel spreaders. The spreaders distribute
the fuel across the fluidized bed. The fluidized bed cell as shown in Figure 1.3 includes the
equipment to accept, distribute, and mix air, fuel, and limestone in a high temperature thermal
oxidization environment. The system is designed in accordance with National Fire Protection
Association (NFPA) Section 850. Underbed air and overfire air distribution systems are provided to
allow proper air flow for uniform combustion, to provide cooling of tramp material, and to optimize
overall bed temperature.

The EPI system is specifically designed to include a bed recycle system to accommodate wood and
tire derived fuel containing wires. The tire bed system is a fluidizing bed bottom, wire
separation, and screening system designed to handle high concentrations of wire left over from the
thermal oxidization of shredded tires and tramp material. The metal is recovered from the rest of the tramp material and
bed media then discharged to the hopper for recycling.

Each of the biomass boilers will include a gas handling system, which includes an induced
draft (ID) fan to pull the boiler flue gas through the economizer. The ID fan exhausts into a
fabric filter baghouse and then to an integral exhaust stack.

Pollution Abatement Control

The fluidized bed system provides an environment to optimize destruction of hazardous air
pollutants and volatile organic compounds. Additional pollution abatement control is included in
this system to comply with air emission requirements.

Particulate Matter Control: Particulate in the gas stream is captured in a pulse-jet baghouse
system. The baghouse captures particulate matter from the flue gas and has removal efficiencies of
99.9+%. The flue gas will then exit through a stack adjacent to the ID fan and baghouse located
just outside of the new cogeneration facility.

Nitrogen Oxide Control: The flue gas from the boiler will be treated in the combustion system
using selective non-catalytic reduction (SNCR) technology to reduce nitrogen oxides. Using the
SNCR will reduce NOx rates to 0.12 lb/MBtu. Urea is injected into the furnace typically above the
over-fire air ports, reacting with the oxides to form nitrogen and hydrogen.

Sulfur Dioxide Control: Since tire derived fuel will be used as a fuel source, each biomass boiler
will also have a bed additive system. The bed additive system will introduce limestone into the
fluidized bed cells in order to reduce sulfur dioxide and other acid emissions. Sulfur dioxide
will be controlled to less than 0.2 lb/MBtu in order to comply with air permit conditions.

Each boiler will include an exhaust stack. Each stack will include an aviation lighting system,
and a continuous emissions monitoring system to measure the stack emissions and provide data
reporting. The system will monitor carbon monoxide (CO), oxygen (O2), NOx,
SO2, reagent slip, and opacity. The data is recorded in the facility supervisory
control and data acquisition (SCADA) system.

Ash Handling System

The fuel will primarily consist of clean biomass sources; therefore, the ash content is expected to
be low, less than 1.0-3.0% of the fuel burned. The ash stream consists of a bottom ash stream and
a flyash stream. Bottom ash will be automatically removed from the biomass boiler with mechanical
conveyors and augered into a hopper outside of the building. Fly ash will be collected at multiple
points along the flue gas exhaust train, including boiler hoppers, mechanical dust collector
hoppers, and baghouse. The flyash system will be a mechanical pneumatic system consisting of
rotary air-lock valves, screw conveyors, drag conveyors, and storage container. The ash collection
hoppers will include water nozzles to keep ash wet and minimize dusting into the plant area.

The ash generated from combustion will be delivered to the landfill or taken off site to potential
end-users. Ameresco will be responsible for ash removal, and the cost is included in the
performance period expenses.

1.2.1.3 ECM 1 Operation

ECM 1 will be operated continuously to produce steam and power for SRS, with the primary
mission of meeting the Annual Steam Guarantee (ASG). The ASG is the total amount of steam output
from the biomass boilers as defined in Section 1.2.7.4. During normal operation, steam produced
from the boilers will flow through the condensing steam turbine. Steam required for the
cogeneration facility auxiliaries and the export steam required by the site will be extracted from
the turbine. The balance of steam will continue through the turbine to generate additional green
power. As required by SRS, the cogeneration facility will be operated to provide steam at 350 psia
through the existing Government-owned distribution system to the users in the F and H Areas.

Scheduled outages will not exceed one per year and only one boiler will be taken down at a time for
planned maintenance. In the unlikely event that both boilers are inoperable, Ameresco has made
provisions and connections for bringing temporary boilers to the site to ensure the supply of
steam.

Projected steam demands of the site are based on information provided in the SRS Site Projection
Profile provided by Government personnel. The projections upon which the cogeneration facility
performance model is based was provided by government personnel in the SRS Site Projection Profile
and shows that annual steam loads will differ for the next 20 years as shown in Table 1.1. Due to
these changes in operation and the anticipated variation in weather from year to year, it is
proposed that the new cogeneration facility will be operated to produce a fixed quantity of steam
each year, the ASG. As the demand for exported steam decreases, the amount of green power
generation will increase, up to the ASG.

Ameresco staff will be responsible for operating and maintaining the cogeneration facility
throughout the contract term as detailed in Section 5.2.7.1, and the cogeneration facility will be
continuously manned by Ameresco staff as described in Section 5.2.7. However, this Final Proposal
excludes any operation and maintenance obligations on the part of Ameresco except as detailed in
Section 5.2.7.1

1.2.2 Location Affected

During the Initial Proposal kickoff meeting, the Government presented three sites as potential
locations for the new cogeneration facility. The selected site is shown in Figure 1.4 below and
was agreed upon by SRS, the M&O Contractor, and Ameresco based on an evaluation of many factors,
including distance to existing utility connections, available acreage, accessibility, security
concerns, and environmental impacts. A site-use permit was obtained and is currently being amended
to include the electrical feeder to the F Area, the river water piping tie-in from the C Area, the
process water outfall to Upper Three Runs Creek, and improvements to the Old Burma Road/C Road
intersection.

1.2.3 ECM 1 Interface with Government Equipment

Title to all Ameresco installed equipment will transfer to the Government at the time of
Government acceptance of an ECM. Title to the biomass fuel will transfer to and vest in the
Government simultaneously with Ameresco’s receipt of the biomass at the fuel handling yard. For the
sake of clarity, ECM 1 will interface with existing Government equipment at the utility
interconnections as described in this section. The installation of utility interconnections
required for the new cogeneration facility are included in the project implementation cost and the
installation will be Ameresco’s responsibility; however, the SRS M&O Contractor will retain O&M
responsibility including repair and replacement for the utility interconnections and utility
distribution systems. Table 1.2 provides a summary of the utility interface and the scope of O&M
responsibility for the utility systems. Ameresco and the SRS M&O Contractor will enter into an
agreement that will provide the cogeneration facility with utility services to include river water,
sanitary sewer service, backup electrical power, and domestic water service. A Power Services
Utilization Permit (PSUP) form will be completed by Ameresco prior to construction of utility
interconnections. Utility meters will be installed to measure usage. It is proposed the
Government will incur the cost for the cogeneration facility’s non fuel utilities. These Post-ECM
Implementation Costs have been factored into the annual savings. The annual consumption and costs
of the utilities are shown in Table 1.6, and the unit cost used for each utility is shown in Table
4.2. Refer to Section 5.2.7.1 for operation and maintenance responsibility.

Infrastructure services (site facility operations and maintenance) are primarily the responsibility
of the Site M&O Contractor. M&O Contractor personnel operate and maintain the SRS utility systems
and manage site environmental programs. On site DOE personnel are charged with oversight of M&O
Contractor operations although M&O Contractor personnel often render project or program decisions
for the Government. Therefore, for purposes of this proposal, the use of the term “Government” is
applicable to DOE and M&O Contractor. For example, the term “Government caused delays” includes
any delays caused by government and/or M&O Contractor personnel. Although the M&O Contractor makes
operational decisions for the systems they operate and programs they manage, only DOE personnel,
i.e. Contracting Officer and Contracting Officer’s Representative (COR) will provide project and
program decisions affecting work performed by Ameresco or Ameresco subcontractor personnel
resulting from this proposal.

Steam Distribution System

Steam produced from the boiler at 850 psig and 825°F will flow through the turbine, or
through a pressure reducing valve (PRV) and desuperheater if the turbine is not operating. From
the turbine or PRV, the steam will be exported to the SRS distribution system, with a small
percentage going to the cogeneration facility DA tanks. Flash steam from the continuous blowdown
flash tank is supplied to a low pressure header to supplement the steam requirements of the DA.

The steam exported to the distribution system will be delivered at 350 psig 450oF. A
new 12” carbon steel pipe will be routed above-ground from the cogeneration facility (exiting from
the turbine or PRV station) to the existing steam line located across Burma Road. A steam meter
will be installed in the line to measure steam exported from the cogeneration facility, as well as
a steam meter on the flow exiting the boilers to measure the total amount of steam produced. The
new cogeneration facility export connection is approximately 3 miles closer to the F and H Areas
than the existing D Area plant, providing increased distribution system efficiency from decreased
line losses. The approximate point of interconnection is shown in the photograph below:

Domestic Water

A 2” domestic water line will be installed to serve plant potable water needs such as bathrooms,
utility sinks, showers, and eye wash stations. The new water line will connect to the existing
domestic water

header located outside of the nearby industrial water treatment plant, located
approximately 0.3 miles east of the cogeneration facility. Domestic water usage is expected to be
minimal (5-10 gpm) and used for sink, lavatory, and maintenance requirements. Annual consumption
is expected to be approximately 2600 kilogallons (kgal). The domestic water interconnection will
be designed per M&O standards and permitted as required by the SCDHEC.

Process Water

River water will be used as the water source for all process and fire water. The process water
usage includes boiler feedwater, cooling tower makeup water, water treatment regeneration cycles,
and cogeneration facility service water. The river water will be supplied from Building 681-3G,
the water pump house, through an existing distribution system and pump station. A new 12” ductile
iron line will be routed underground from the existing C Area valve house (refer to Figure 1.6) to
the cogeneration facility site following the route of the abandoned steam line from the C Area, and
then diverting off of the route through existing vegetated areas to the site. Routing through the
vegetated area will reduce the new distribution pipe route by approximately 1/2 mile. The specific
routing is shown on the site drawing which is included in the drawing package (Volume III). The
peak make-up requirement to the site is 2200 gpm; this would occur if the system was operating at
full capacity and if all the regeneration cycles of the water treatment system were occurring at
the same time. Normal operations will use 600 gpm. Annual river water consumption will average
around 450,000 kgal.

To ensure there is adequate redundancy and back-up for the site river water source, in addition to
the installation of the new distribution line a new pump skid (identical to the P-10 skid) will be
installed to replace the pump, P-4, located inside the water pump house (Bldg 681-3G). The new
pump will be used as a backup for P-10 and be designed with a 19.8” impeller size (600 hp motor.)
Other components to be installed with the new pump include:

	 	•	 	Rework of the existing suction pipe
	 
	 	•	 	Installation of isolation valve in suction pipe
	 
	 	•	 	Installation of flow control valve & flow meter
	 
	 	•	 	Installation of instrumentation and valves setup (duplicate system to the P-10 skid)
	 
	 	•	 	Control modification to allow the pumps to automatically operate based on
system requirements

Site Outfall

A new 24” high density polyethylene pipe will be routed from the cooling tower basin to Upper Three
Runs Creek. The pipe will be installed underground and follow the natural topography of the land.
A new outfall structure will be constructed next to the cooling tower to allow for flow monitoring
and effluent testing. Process waste water and the storm water runoff will be discharged to the
outfall. The storm water system includes collection piping to catch basins which will divert the
storm water to the site

retention pond. The retention pond will discharge to the outfall. The outfall will be
permitted under the site National Pollutant Discharge Elimination System (NPDES) permit.

Sanitary Sewer

The bathrooms and fixtures located in the cogeneration facility and in the administration building
will connect to the existing sanitary sewer system via a 4” polyvinyl chloride (PVC) pipe and be
pumped using a new lift station. The line will connect upstream to the 607-91G lift station
located approximately 0.3 mile east of the cogeneration facility. The sanitary sewer
interconnection will be designed per M&O standards and permitted as required by the SCDHEC. Annual
discharge is expected to be 2,600 kgal.

Electrical System

Power will be delivered to the existing F Area substation at 13.8 kV from the cogeneration
facility. The power feeder from the cogeneration facility will be approximately 7,600 feet and
will be routed in a combination of overhead pole mounted transmission line and underground duct
bank where required in the F Area. The feeder will connect to an existing spare breaker cell in
the metal-clad switchgear lineup at 251-F. The breaker cell shall be unit 101A, 101B, 206A, or
206B as deemed suitable by Ameresco and the Government. The interconnection scope of work includes
a compatible circuit breaker, multifunction utility-grade numerical relay and instrumentation, and
a 15kV class line potential transformer (PT) (either outdoor on feeder or indoor in a top-hat
structure added to the existing switchgear). Existing bus PT secondary sources and existing
station direct current (DC) battery sources are to be tapped as-is without improvement. Ameresco
will utilize as-is or improve existing lockout relays and circuit breaker auxiliary contacts where
no spare contacts or similar status points are available. Where such improvements are not possible
due to the limitations of existing equipment, Ameresco will propose a solution to the Government
(e.g. interposing relays, SCADA outputs, etc.). Ameresco assumes that the subject devices either
as existing or improved, sufficiently indicate the operation of distribution and transmission level
switching to determine when the generation system is unintentionally islanded from the utility
source.
Where transfer trip capability is required or determined to be best practice for protection of the
proposed generation system, transfer trip facilities are to be derived from existing utility
protective relaying equipment installed at 251-F. The scope excludes special or upgraded SCADA
communications between 251-F and electrical utility operator. This scope is limited to the feeder
circuit breaker at 251-F used to service the proposed generator plant and the primary protection
described. The scope does not include other feeders at 251-F or any other upstream devices that
are not impacted by the project (e.g. transformer secondary or primary protective devices and
features, transmission-level protective devices and features). To insure appropriate coordination
with the existing F area electrical distribution equipment, SRS will need to supply required
load-flow, short-circuit, and intertie relay settings. Ameresco will prepare a transient
study if deemed necessary for design.

Power at the new cogeneration facility is generated at 13.8 kV and is connected to a main 13.8
kV switchgear unit identified as “HVS”. “HVS” is equipped with six (6) breakers. Breaker “52G” is
utilized for the main generator breaker and is complete with required protective and synchronizing
relaying. Breaker “52-4160” feeds a 7500/9375 kilovolt amperes (KVA) transformer “ATX-2” that
steps down to 4160 volts alternating current (VAC) for large motor loads. Breaker “52-480” feeds a
2500/333 KVA

transformer “ATX-1” that steps down to 480 VAC for all the remaining facility power
distribution loads. Breakers “52-SG-1” and “52-SG-2” are utilized as feeders from two 1500 kW
standby generators. Breaker “52U” is the tie breaker that feeds power to and from the F Area.
This breaker will also be complete with all required protective and synchronizing relaying. The
13.8kV switchgear “HVS” and transformers “ATX1” and “ATX2” are located in the electrical room in
the new cogeneration facility.

D Area Electrical Feeder

A new feeder will be installed in the D Area to provide continued electrical service to both the D
Area and the TNX Area when the 484-D Power Plant is either dismantled or demolished and to reduce
the annual SCE&G costs associated with O&M of Station 41. The new feeder will be a #2 aluminum
conductor, steel reinforced (ACSR) overhead 13.8 KV 3 phase line that will run from the existing
overhead line in the vicinity of Barricade 3 at the entrance to D Area, down the east side of the
entry road to a point roughly 80’ short of the 115 KV line crossing, turn east and run across
country paralleling the 115 KV line just outside of its right of way (ROW) until it is terminated
with a tie-in to an existing 3 phase line crossing at the back of D Area. By connecting to this
line, the new feeder will be able to power the TNX complex without any further modifications to the
existing overhead system. Fused sectionalizing switches will be installed at each end of the new
line. The recloser currently installed back across the Highway on the line being tapped will be
recalibrated to reflect the addition of the line extension to D Area.

Before turning east at the 115 KV line, the new line will cross a CSX railroad main line. A
complete design/permitting package will be developed and submitted to the railroad for their review
and approval. Initial filing fees for this permitting process are included, but any ongoing fees
due CSX are excluded from this proposal and will be the responsibility of the Government.

The addition of this feeder will result in monthly O&M savings currently paid to SCE&G to maintain
the equipment in Station 41. The annual savings is $75,000 (10% reduction of the current O&M
charge to SCE&G).

L Area Capacitor Work

The single 6 megavolt ampere reactive (MVAR) capacitor bank currently sitting on the L Area site
will be installed on a new concrete pad in the grassy area across the access drive on the northwest
side of the switchgear building, and connected to existing breaker 2-6 within substation 151-1L.
New cable and cable tray will be installed in the basement beneath the switchgear to the northwest
wall where spare sleeves will be used to exit the building. A new underground duct bank will be
run from the building wall under the drive to the new pad for the capacitor bank connecting the
capacitor. Spare 4” conduits will also be provided stubbed out from beneath the new pad for future
connections to other systems. The capacitor bank will be interfaced with the existing SRS SCADA
system. The actual location in the grassy area will be coordinated with the proposed installation
of a future grounding transformer. The drive and associated curbs will be replaced after the duct
is installed.

We have been advised that several capacitor cells are defective. These will be replaced with
available spare cells to the extent possible. These are the only repair efforts included in the
installation of this capacitor bank which has been sitting out in the weather unprotected for some
time. Any other repairs necessary to get the bank into fully operational condition are not the
responsibility of Ameresco.

Installation of this existing capacitor bank will assist SRS in maintaining their power factor as
close as possible to the minimum required by the utility company before penalties are assessed.

1.2.4 Proposed Equipment

The proposed ECM 1 will include the major components as described in Section 1.1. An
equipment list and manufacturer’s literature for the boiler and turbine system is included in
Appendix C.

1.2.5 Expected Lifetime

The combustor/boiler and turbine components have an expected lifetime of 25-30 plus years.
Ameresco will repair and replace components to ensure the continuous operation of the equipment
throughout the contract performance period.

1.2.6 Physical Changes to Existing Equipment or Facilities

The cogeneration facility will be located on an unoccupied area of the SRS. The actual site
will not impact or require physical changes to the existing facilities; however, there are changes
required at other areas of the reservation as a result of operations of the new cogeneration
facility.

These include the following:

	 	•	 	D-Area Electrical Feeder
	 
	 	•	 	Pump and Controls Replacement in Building 681-3G, Water Pump Station
	 
	 	•	 	Installation of existing capacitor at the L-Area Substation 151

1.2.7 Savings Proposed

The annual savings associated with ECM 1 are based on the avoided cost of operating and
maintaining the existing D Area Plant. The energy savings result from using a more efficient
boiler and steam distribution system and the energy cost savings from using biomass as the primary
fuel source in place of coal.

1.2.7.1 Annual Project Savings Overview

In order to calculate the annual savings, the baseline costs of the D Area plant were
collected and the Post-ECM Implementation Costs were computed. The baseline costs of the ECM are
[**] of the D Area plant. The avoided baseline costs for utilities are shown as [**] on Schedule
DO-4 and the avoided operations and maintenance costs are shown as [**] on Schedule DO-4. The
Post-ECM Implementation Costs that will be incurred by SRS are the costs of [**] and the costs for
the [**] associated with the

operation of the [**], as compared to the existing D Area plant. Thus, the annual savings
from the ECM equals:

Annual Savings = [**] as escalated annually.

Annual savings will [**] throughout the contract term. Table 1.3 provides a summary of the annual
Post-ECM Implementation Costs, as escalated, that will be determined annually and Other Energy
Savings and O&M Cost Savings, as escalated, which are herein agreed to by the Government and
Ameresco for the contract term associated with ECM 1. The utility costs and annual savings are
based on current year dollars, but are escalated using the appropriate National Institute of
Standards and Technology (NIST) factors (refer to Table 4.3 for the applicable escalation rates) to
the date of government acceptance of the project (Project Year 1, CY 2012). Future year O&M cost
savings have been escalated at [**]%. The basis of the escalation is the Consumer Price Index for
the Southeast region of the US (as reported by the US Department of Labor; Bureau of Labor
Statistics) from May 2004 to May 2007, the latest 3 years of data available. The annual increases
for those years have been 2.91%, 4.38%, and 2.71%, for an average escalation rate of 3.33%.
Utility savings, with the exception of the non-fuel utilities, are escalated using the NIST utility
escalation rate for industrial users, sorted by fuel type. Non-fuel utilities are escalated at
[**]% per year.

The following subsections present the assumptions and methodology for establishing the
baseline cost and baseline energy consumption for the D Area Plant & Substation, the annual savings
calculations, and the performance guarantee for the proposed project.

1.2.7.2 Annual Energy Baseline Consumption & Costs

The D Area Plant uses four (4) coal fired boilers to provide steam and power to SRS and is
contractor operated and supported by the engineering group of the M&O Contractor. The annual
energy consumption and operations costs data for the D-Area Plant was developed to establish the
baseline for
this ECM. The baseline operations and maintenance table (Table 1.4) was developed using the
monthly averages of the latest two years of cost data for all O&M of the D Area Plant. The O&M
costs include [**]. An additional annual reduction of [**] of the D Area Plant and the Substation,
[**] the annual O&M Cost Savings. The detailed breakout of the 2006 — 2007 O&M costs are shown in

The annual energy consumption for the D Area plant is based on the amount of coal utilized to
produce steam for SRS thermal demand and for SRS power supply. The baseline consumption was
determined using monthly averages for the latest two years of fuel usage data. The average annual
amount of coal consumed for the past two years was [**] tons, which is used as the agreed upon
energy savings baseline. The baseline for energy cost is determined by the product of the baseline
energy consumption times the baseline cost of coal. The baseline cost of coal, as provided by SRS
and agreed upon, is $[**] per ton of delivered coal. Thus the baseline energy cost is agreed to be
$[**]. Currently, all electric power required by the site above the net output of the D Area power
plant is procured from SCE&G under Rate Schedule 23 and Rate Schedule 60. The energy charge is
[**] per kWh and the average demand charge is $[**] per kW for load over 20 MW. The baseline power
export from the D Area plant was determined using
monthly averages for the last two years of data. Refer to Table 1.5 for a summary of the fuel
consumption and the net power exported from the D Area plant.

1.2.7.3 Annual Energy Savings Calculations

The annual savings are determined by calculating the baseline annual O&M cost for the existing
plant, plus the annual energy cost as presented in the previous section. The annual savings are
then adjusted to account for the cost to be incurred by SRS to purchase additional power from SCE&G
and to account for the Post-ECM Implementation Costs to be incurred by SRS for the non fuel
utilities of the new cogeneration facility.

The additional future cost of purchased electricity is calculated using the [**] (refer to Table
1.5) [**], the annual net “green” power generation of the new cogeneration facility will [**].
Refer to Table 1.6 for performance of the plant throughout the performance period

Using the projected SRS steam demand of each of the years during the performance period, net annual
green power generation will vary each year of the performance period and therefore the amount of
power purchased will change. The annual cost associated with the power purchase is determined by
the [**]. Future unit cost for electricity is escalated using the applicable NIST factor and is
factored into the DO Schedules (defined below).

The annual savings are also adjusted to account for the Post-ECM Implementation Costs incurred by
SRS to provide non-fuel utilities to the new facility. This includes the cost for river water,
sanitary sewer, and for domestic water. The annual consumption for each of these utilities is
shown in Table 1.6.

The net estimated annual savings for ECM 1 is $33,181,197 for the first year of the performance
period (2012).

1.2.7.4 ECM 1 Performance Measurement

The ECM performance will be measured using the flow output (via a steam flow meter) of the two
biomass boilers. Measuring and totalizing the steam production permits for flexibility to make use
of this steam to meet the thermal and electrical demands of SRS while allowing for normal seasonal
variations and adjustments for expected future load changes. The Annual Steam Guarantee (ASG) for
ECM 1 will be 1,759,485 kilopounds per year (klbs/yr) of steam using an annual fuel consumption of
[**] MBtu/yr and is shown in Table 1.6 — ECM 1 Post-ECM Implementation Facility Performance. The
ASG will remain set throughout the performance period; however, the electrical output and the steam
export output will vary. Annual biomass costs are calculated based on meeting the ASG and will be
adjusted only when the actual steam production for ECM 1 exceeds the ASG; refer to Section 1.3.1.2.

Ameresco proposes to produce additional steam from the cogeneration facility above the ASG, unless
notified otherwise in writing by the contracting officer, provided that the Government compensates
Ameresco for the incremental cost of biomass annually. Additional steam may be used for power
generation or for thermal energy. Excess delivered steam above the ASG will be paid for by the
Government as described in Section 1.3. Further increase in green power generation due to excess
steam production will result in additional annual savings and will be documented in the annual M&V
report.

The planned Post-ECM Implementation Costs for Ameresco to operate and maintain ECM 1 are included
in the performance period expenses set forth on Schedule DO-3. The performance period expenses
include the costs necessary for Ameresco to provide operations and maintenance of the new
cogeneration facility including fuel (biomass and fuel oil for backup), personnel, daily operations
and maintenance, routine and non-routine repair and replacement costs, and operations management to
meet the ASG.

Post ECM Installation Cogeneration Facility Performance

The data in Table 1.6 is derived from the output of energy modeling software (Thermoflex), from
vendor data for equipment efficiency, and from using the steam load data provided by the Government
(refer to Table 1.1). The following paragraphs are an overview of the general methodology of the
performance calculations.

1.2.8 Utility Interruptions

The utility interconnections are described in detail in Section 1.2.3. It is anticipated that
these connections will be made with minimal interruption to the SRS site. Any necessary
interruptions will be coordinated and scheduled in advance with SRS personnel and with M&O site
personnel. The shutdown of the D area plant and the start-up of the new cogeneration facility will
be coordinated with SRS personnel and D Area site personnel to allow for minimal interruptions
during transition.

1.2.9 Agency Support Required

Ameresco will continue to work with the Government as the project moves through the final
design and the construction period. Support from the Government’s engineering, contracting, and
maintenance units, as well as management will be required for continued success of the proposed
project. The Government, through its M&O Contractor Environmental Support Section will be
responsible for processing the storm water management permit, the final site use permit, the
National Environmental Policy Act (NEPA) document, domestic water permit, sanitary sewer permit,
wetland permit, and the new outfall into the site NPDES Permit. Refer to Section 3.2 for a
description of the environmental permit and documentation required for this ECM.

1.2.10 Potential Environmental Impact

Refer to Section 3.0 for environmental benefits and impacts from both ECMs.

1.2.11 ECM Property Ownership

As approved under the BAMF Contract, title to all contractor-installed equipment proposed
under this ECM will vest with the Government upon its acceptance of such ECM or the date that
commercial operations begin, whichever occurs earlier.

1.2.12 ECM Project Schedule

The construction schedule will be developed using Primavera P-6 software and submitted to the
contracting officer. The following table shows the major milestones of the design and construction
period.

1.3 BAMF Project Components

1.3.1 BAMF Resource

ECMs 1 and 2 will require approximately 322,118 tons of forest residue biomass per year to
meet Ameresco’s ASG and approximately 385,000 tons of forest residue biomass per year to operate at
design capacity. For such calculation of tons, Ameresco used a heating value of 4,300 Btu/lb from
forest residue. Ameresco intends to procure both clean biomass and biomass derived fuel (BDF).
Clean biomass includes forest residues, some urban waste, untreated wood pallets, and residue from
lumber processes. BDF includes urban wood waste and tire derived fuel and will only be used in
connection with ECM 1. There are numerous sources of clean biomass within a 100 mile radius of the
SRS site, including within the SRS Forest. The following sections describe available BAMF supply,
BAMF pricing, and BAMF acquisition.

1.3.1.1 BAMF Supply

Following several discussions with the local office of the U.S. Forest Service and SRS
personnel, Ameresco proposes to assume responsibility for the fuel procurement and intends to meet
the biomass fuel requirements for ECMs 1 and 2 through purchases from local biomass suppliers.
This responsibility shall include the right to validate, verify, and sell any carbon credits, but
not renewable energy certificates, which may be obtainable from the ECMs and their associated
operation and activities. Ameresco will consult with the Government concerning the design,
validation, and verification for carbon offset credits and will make reasonable commercial efforts
to obtain carbon offset credits which may be associated with the ECMs. Those credits may arise
from the substitution of biomass residues for use in lieu of fossil fuels, and the use of biomass
from onsite activities, including those from forest reforestation and working forest activities.

BAMF Deliveries

There will be deliveries of biomass and other BAMF fuel scheduled daily, Monday through Friday
(normal operations), throughout the contract performance period. It is estimated that up to 60
trucks may enter and depart the C and Burma Road location each day, five days per week. It is
anticipated that deliveries will be accepted from 7:00 AM to 7:00 PM although the exact hours may
vary by season and/or supplier. Acceptable delivery hours will be established with each biomass
supplier. Following meetings with SRS personnel, Ameresco has agreed to minimize the number of
deliveries departing the site at the C Road traffic signal from 6:30 to 8:30 AM to accommodate
arriving SRS personnel turning left at that traffic signal. Ameresco has been given assurance, and
this proposal is predicated upon biomass delivery vehicles being permitted to enter and depart the
SRS reservation at any of the available (open) gates and not be limited to just the Aiken and
Jackson Barricades.

Drivers of the BAMF delivery vehicles will be required by Ameresco to obtain a permanent (one year)
site badge and to comply with SRS vehicle safety and site entry requirements, except as noted
above.

Ameresco has conducted many discussions and met with potential fuel suppliers within the past few
months. Ameresco is currently working primarily with [**], to obtain biomass fuel supply contracts
needed for the ECMs, although there are additional suppliers within the region that continue to
express an interest in becoming a biomass fuel supplier. All are large companies with capabilities
of harvesting, collecting, and delivering wood chips to end users and have contracts to harvest
timber in the SRS Forest.

1.3.1.3 BAMF Acquisition

Ameresco may enter into an agreement with one or more biomass suppliers. Ameresco will also
attempt to secure from each supplier a fixed fuel price for as long a term as possible.

1.3.2 BAMF Transportation, Metering, & Delivery

1.3.2.1 BAMF Transportation & Delivery

The biomass will be delivered from the suppliers using trucks with live bottom feeders,
self-dumping trucks, or trucks with high-side trailers. Typically, each of the larger trucks has
the capacity to hold approximately 120 cubic yards of fuel per load. The smaller self dumping/end
dump trucks typically only carry about 50 cubic yards of fuel and will be used primarily for BDF
waste sources or for larger unprocessed fuel. Actual loads may vary with the density of the fuel.
Normal truck deliveries will be arranged to be made Monday through Friday.

1.3.2.2 BAMF Metering

Woodwaste is commonly measured in units of weight and volume such as in tons, truck loads, or
cubic yards, rather than in units of energy. For this proposal, the higher heating value of
biomass is about 4,300 Btu/lb since the majority of the fuel will be from forest residues and is
typically high in moisture. The fuel supply will be tracked and recorded using the truck scale
tickets. Periodic testing will be done on the fuel to determine the composition and the heating
value.

1.3.3 BAMF End-Use Project

1.3.3.1 BAMF End-Use Demand

End use of the biomass source was calculated utilizing forest residue as the main fuel source
to meet the ASG. Forest residues for the Carolina area are typically high in moisture with heating
values in the range of 4,100-4,600 Btu/lb. For the design basis and end use demand calculations, a
higher heating value of 4,300 Btu/lb was used to determine boiler feed input. At this heating
value, the boiler efficiency is expected to be 70%. At these conditions, the expected annual fuel
use for ECM 1 is 317,118 tons a year of biomass consisting of forest residues.

1.3.3.2 BAMF End-Use Operations & Maintenance

Ameresco will retain operational and maintenance responsibility for the cogeneration facility
and equipment installed at the cogeneration facility, described in Section 5.2.7.1 of this
proposal.

2.0 ECM 2 DESCRIPTION

2.1 ECM Summary Schedule DO-4

Pricing Schedule DO-4 is included in Section 6.0, Proposal Pricing Information.

2.2 ECM #2: Biomass Heating Plants for K& L Areas

2.2.1 Detailed Description of ECM

2.2.1.1 ECM Summary

ECM 2 includes the installation of biomass heating plants in the K Area and the L Area. These
new heating plants will replace the existing fuel oil-fired boiler plant located in the K Area that
currently serves heating loads in both the K and L Areas. The two existing 30,000 and 60,000 lb/hr
steam boilers are in poor condition and are now vastly oversized for the current load (estimated by
SRS personnel to be approximately 7,000 PPH of steam in each area at design conditions). The
existing 30,000 lb/hr boiler has been utilized as the primary boiler during the most recent years,
due to the large reduction in load from the original design. Currently steam is produced at 150
psig to distribute to the K and L Areas and reduced inside the secure areas for use at 30 psig or
less. By decentralizing the existing plant and providing local boiler systems in both the K and L
Areas, the losses from the existing aboveground 2.5 mile, 6-inch steam line running from the K Area
to the L Area will be eliminated. Additional efficiency gains are made from the right-sizing of
the new heating plants to match existing loads.

The heating plants are each sized to provide a continuous availability for supply of steam to site
end-users in the K and L areas during the typical heating season of December through mid April.
The individual site demand was based on fuel oil consumption data for the past 5 years. The system
is designed using applicable national codes and standards for steam plants and specific site
standards (refer to Appendix D). Previously, conceptual design drawings were submitted to the site
for review prior to issuance of this final proposal; a draft version of the “issued for pricing”
drawings is included in Volume III of this proposal. Finalized “issued for construction” drawings
will be submitted to the government for concurrence throughout the first year of the construction
as major equipment items are ordered and the design drawings are finalized.

Implementation of this project provides utility savings resulting from 1) The elimination of losses
from 2.5 miles of existing steam distribution piping between the K and L Areas; and 2) Improved
operations from properly sized boilers, and the fuel cost differential in switching from fuel oil
to clean biomass. Annual savings are over $1.1 M for this ECM.

This proposal includes the procurement and installation of the new equipment, the support
facilities, all auxiliary systems and controls, and utility tie-ins required to connect the new
heating plants to the K and L Area distribution systems, as well as ongoing O&M and environmental
compliance of both heating plants for the contract duration.

2.2.1.2 ECM Process Description

This ECM includes two major components for each of the proposed heating plants: 1) Biomass
fuel storage system, and 2) combustion/boiler system. Each new heating plant will be installed in
an enclosed building with an adjacent covered shelter to house the wood fuel storage and delivery
equipment. Biomass fuel will be delivered to both heating plants by Ameresco personnel from the
fuel processing yard of the Biomass Cogeneration Facility. The fuel delivered to each of these
heating plants will be clean biomass (refer to Section 1.3). The clean biomass will be used as the
primary fuel source for two new wood waste combustor boilers to supply steam to the K and L Areas.
Each boiler system will be designed to generate 10,500 PPH of saturated steam at 135 psig.

Biomass Fuel Storage System

The fuel storage area consists of the storage system and feeder to the combustion system. The
components of this system are recommended to minimize equipment at each site and to provide maximum
automation to each of the heating plants. Ameresco personnel will employ tractor-trailers to
transfer the biomass fuel from the fuel yard at the cogeneration facility to both the K and L Area
heating plants. The tractor-trailers will be parked in the new fuel storage shelter bays, one at
each heating plant location. Each tractor-trailer is equipped with a walking floor-bed
installation for the automated transfer of fuel to the stationary metering bin at each heating
plant. The metering bin utilizes augers to feed the fuel into the combustion system.

The flow of fuel is controlled by an integrated direct digital control (DDC) system that automates
the flow of fuel from the walking-bed to the metering bin, and from the metering bin to the
combustor, based on input signals (and required safeties) to maintain steam pressure at the output
of the boiler.

Fuel Storage System components for each area (K and L) includes:

	 	•	 	Tractor trailer with walking bed for fuel feed
	 
	 	•	 	Fuel storage shelter bay
	 
	 	•	 	Main fuel bin and auger to feed combustor

Combustion/Boiler System

One combustion/boiler system will be located in each area, in a separate, enclosed bay connected to
the fuel storage shelter bay. The system proposed is manufactured by Hurst Boiler & Welding
Company, Inc., and is designed specifically for the combustion of solid waste fuels to optimize
energy recovery and minimize air emissions. Refer to Appendix C for manufacturer cut sheets.

When there is a demand for steam the biomass is augered from the fuel storage bin into the
combustor, where the biomass begins to burn by the use of three levels of air directed into the
combustion zone. The primary air is forced into the combustion zone from beneath the fuel grates
(on which the fuel rests during combustion). The secondary air is forced through side grates, and
the tertiary air comes through the side

of the cast refractory to keep unburned ash from exiting the unit. The primary combustion zone is
lined with high-insulating value, cast refractory ceramics to minimize radiant heat losses from the
unit exterior.

A similar, secondary ceramic chamber fired at 3,100°F is included between the primary combustion
zone and the boiler to allow for an extended combustion zone. The extended retention time in the
secondary zone ensures the additional combustion of the biomass and reduces emissions. The
appropriate combustion temperature is maintained by adjusting fuel feed, fan speed, and air intake.

Each boiler will be equipped with an auxiliary burner to allow for the firing of fuel oil for full
output capacity of the boiler. Fuel oil will be used for pilot lighting on startup, and as a
back-up emergency fuel source only. Each boiler has the capacity to produce up to 10.5 k-lb/hr of
135 psig steam when the combustion system is operated at full output. Each is a 2,600 sq ft unit,
with 2 pass design and includes standard instrumentation, rear furnace access door, and
air-operated soot blowers. Downstream of each steam boiler, the exhaust gas will go through a
multi cyclone which reduces the particulate matter in the exhaust gas by 70%. The exhaust stacks
will be equipped with appropriate lighting as required for on-site helicopter travel.

Boiler/Combustion System components for each area include:

	 	•	 	Metering Bin Feeder
	 
	 	•	 	10.5 MBtu/hr combustion unit
	 
	 	•	 	Full-capacity fuel oil burner
	 
	 	•	 	Steam heat recovery boiler
	 
	 	•	 	Multi cyclone
	 
	 	•	 	SCADA system
	 
	 	•	 	Automated ash removal system
	 
	 	•	 	Exhaust stack with aviation lights
	 
	 	•	 	Boiler auxiliaries
	 
	 	•	 	Air compressor for L Area
	 
	 	•	 	Water treatment skid for L Area
	 
	 	•	 	Fuel Oil Storage

2.2.1.3 ECM Operation

Ameresco will be responsible for operating and maintaining the heating plant facilities and
equipment throughout the contract term. Both boilers will be operated by Ameresco as needed to
meet the steam demand as more fully described in Section 2.2.7.3.

Both heating plants will be remote monitored via a telephone modem and using the Site PA system
from the control system at the cogeneration facility. Maintenance and inspection of the systems
will be performed by Ameresco operations personnel from the cogeneration facility. Refer to Table
2.1, which

defines the interconnection and utility O&M responsibility for this ECM. Refer to Section 5.2.7.1
for a detailed description of the O&M responsibilities of each party.

2.2.2 Location Affected

The biomass heating plant at the K Area will be constructed in the same vicinity as the
existing plant, behind the two existing 30,000 gallon fuel oil tanks. The existing fence will be
modified to allow for the construction of a new gate which the biomass delivery trucks will use for
accessing the heating plant. A new facility will be constructed to house the biomass heating
plant, while the biomass fuel storage and feeder area will be located under a covered bay attached
to the new heating plant. For the L Area, a replica of the K Area heating plant will be installed
northeast of the abandoned cooling water basin. The footprint for each system is approximately
2,600 square feet, including an enclosed sound proof control booth. Refer to Figure 2.1and Figure
2.2 for site location plans for each area.

2.2.3 ECM 2 Interface with Government Equipment

Title to all Ameresco installed equipment will transfer to the Government at the time of
Government acceptance of an ECM. For the sake of clarity, ECM 2 will interface with existing
Government equipment at the utility interconnections as described in this section. The
installation of utility interconnections required for the new heating plants are included in the
project implementation cost and the installation will be Ameresco’s responsibility; however, the
SRS M&O Contractor will retain O&M responsibility including repair and replacement for the utility
interconnections and utility distribution systems. Table 2.1 provides a summary of the utility
interface and the scope of O&M responsibility for the utility systems. Ameresco and the SRS M&O
Contractor will enter into an agreement that will provide the heating plants with utility services
to include river water, process sewer service, backup electrical power, and domestic water service.
A PSUP form will be completed by Ameresco prior to construction of utility interconnections.
Utility meters will be installed to measure usage. It is proposed the Government will incur the
cost for the cogeneration facility’s non fuel utilities. These Post-ECM Implementation Costs have
been factored into the annual savings. The annual consumption and costs of the utilities are shown
in Table 2.5, and the unit cost used for each utility is shown in Table 4.2. Refer to Section
5.2.7.1 for operation and maintenance responsibility.

Electrical System

K Area: At the time Ameresco performed the initial field survey, SRS staff were beginning the
process of designing a dedicated overhead 300A, 480V feeder and panel board. This system has not
been installed to date, so a new feeder from the 151-2K substation will be provided as part of the
ECM 2 work scope. New motor control center(s) and associated low-voltage distribution equipment,
lighting, and related requirements associated with the new boiler and fuel handling equipment will
be provided.

L Area: Based on information provided by SRS, the switchgear, 183-2L is available for
interconnection and has adequate capacity for the load of the heating plant. Ameresco will run a
new feeder from 183-2L to serve a new overhead wood-pole distribution line to the proposed boiler
plant site. A new feeder will supply the motor control center and distribution panel(s) required
for the new equipment.

Steam Distribution System

K and L Area: Each new boiler will be connected to the existing steam distribution lines within
each area. The new boiler system will operate at 135 psig and pass through the existing PRV
station for distribution to end users at 30 psig.

Boiler Feedwater

K Area: Existing boiler feedwater services will be utilized for the new heating plant. Ameresco
will use and maintain the existing water treatment system. If the existing well water treatment
plant is not upgraded to produce domestic water prior to project startup, a small water tank will
be installed to hold domestic water for use in the safety shower and eye wash station.

L Area: River water will be used as the source for boiler feedwater for the heating plant. There
will also be a domestic water feeder used as a backup source for boiler feedwater and to feed the
safety shower and eyewash. A new water treatment facility will be installed to treat the water for
suitability of the new biomass boiler.

Process Sewer

K Area: The boiler blow down will connect to the process sewer system that runs to the existing
ash basin.

Permit.

2.2.4 Proposed Equipment

The proposed equipment is described in the previous section and an equipment list and
manufacturer information for the combustor/boiler system is included in Appendix C.

2.2.5 Expected Lifetime

The major equipment components have an expected lifetime of 20 — 30 years. Annualized repair
and replacement costs have been included in this proposal. Ameresco will be responsible for all
repair and replacement required to maintain heating plant operation.

2.2.6 Physical Changes to Existing Equipment or Facilities

Both proposed heating plants will be located outside of the process areas; however, this ECM
proposes to make the following modifications within the K Area:

	 	•	 	The K Area water treatment building will be left in place and existing water
treatment components will be utilized. Ameresco will maintain the water treatment
equipment and building throughout the term of this contract.

	 	•	 	The air compressor located next to the existing fuel boilers in the K Area
will be used for the new biomass combustor system. Ameresco will maintain the air
compressor throughout the contract term.

2.2.7 Savings Proposed

The annual savings associated with this ECM are based on the avoided cost of operating and
maintaining the existing K Area Plant including the distribution system between the K and L Area,
the annual energy savings resulting from using a more efficient boiler, and by using biomass
instead of fuel oil as the primary fuel source. Additional energy consumption savings will be
realized by replacing the K Area plant with two smaller heating plants, which eliminates the 2.5
mile distribution line between the two areas.

Table 2.2 summarizes the annual savings associated with ECM 2. Annual Energy Savings [**] are
agreed to be [**]; however, the annual savings are adjusted each year to account for [**] agreed to
be [**], resulting in a total of $1,188,383. Using the current NIST escalation factors for the
utility savings, the total annual savings for Project Year 1 (assumed to be CY 2012) are
$1,171,260. Future years have been escalated at [**]%. The basis of the escalation is the
Consumer Price Index for the Southeast region of the US (as reported by the US Department of Labor;
Bureau of Labor Statistics) from May 2004 to May 2007, the latest 3 years of data available. The
annual increases for those years have been 2.91%, 4.38%, and 2.71%, for an average escalation rate
of 3.33%. Annual Energy Savings and O&M Cost Savings shown on Table 2.2 are herein agreed to by
the Government and Ameresco for the term of the contract.

2.2.7.1 Annual Energy Savings

The annual savings are based on the avoided cost to operate and maintain the K Area plant
including the distribution system between the K and L Area and the cost of energy required to
produce steam in the existing boilers minus the Post ECM cost of the non fuel utilities for each
heating plant. The savings will be applied to fund the capital cost of the project and to fund the
ongoing performance period expenses throughout the contract performance period term. The
performance period expenses include the costs to operate and maintain the new heating plants such
as biomass and fuel oil cost, labor cost, consumable costs, maintenance costs, repair and
replacement cost, and operation management. The following subsections show the baseline cost and
energy consumption for the existing K Area Plant, the calculations of fuel and operating costs of
the new heating plants, and the savings summary for the proposed project.

2.2.7.2 Annual Energy Baseline Consumption & Costs

Currently the K Area plant utilizes one 60,000 lb/hr fuel oil boiler and one 30,000 lb/hr fuel
oil boiler to serve both the K Area and the L Area facilities via a 2.5 mile steam pipeline. Data
provided by SRS indicates that the 30,000 lb/hr boiler is the primary boiler, with the 60,000 lb/hr
not having run in the past 3 years. Steam is produced at 150 psig and is reduced to an operating
pressure of 30 psig for each site. The existing boilers are oversized and past their useful life,
and are currently a costly maintenance issue.

In order to calculate the annual savings for this ECM, a baseline was developed to depict the most
reasonable representation of the annual energy determined by taking the average consumption of the
past 5 years, and to determine the annual O&M costs which were based the average of the past 5
years as shown in the following tables:

Using the past 5 years of data for fuel oil consumption, the annual average consumption is
309,631 gallons. The current price of fuel oil is $2.13 per gallon; therefore, the baseline energy
cost is $659,514.

The annual savings for ECM 2 are equal to the O&M cost savings plus the annual energy costs
baseline minus the post-ECM non-fuel energy costs. The annual savings for ECM 2 is $1,188,383 for
the current year and $1,171,260 for Year 1 (2012).

2.2.7.3 Annual Heating Plant Performance

For ECM 2, heating plant performance is based on heating plant availability to provide steam
to the K and L Areas, with outages no longer than a period of a week (seven continuous days) at any
one time, during the typical heating season of December through April up to a maximum of 33,300
klbs/yr (Availability Guarantee). The annual fuel cost for this ECM has been calculated using an
annual steam production of 33,300 klbs. If the steam load for the heating season is lower than
33,300 klbs and therefore the fuel consumption is lower, the difference will be reconciled as
described in Section 1.3. It is expected there will be a reduction of 10% of the steam load due to
the shutdown of the steam line between the two areas. If the steam production is higher due to an
increase in either Area’s demand, the fuel cost will be adjusted annually. Annual fuel costs are
calculated based on meeting the Availability Guarantee and will be adjusted annually on actual
steam production and actual fuel consumption (Refer to Section 1.3). The expected heating plant
performance is shown in the following table:

The non-fuel utilities consumed at each of the heating plants are to be incurred by the
Government. The Post-ECM implementation cost has been deducted from the annual savings for each
year of the performance period. The water consumption is based on the Availability Guarantee and
the electricity consumption is based on the load of the heating plants for the typical heating
season. The annual utility cost was calculated by multiplying the consumption by the unit cost of
the utility (refer to Table. 4.2). The unit cost of the utilities is escalated using the NIST
values and the [**]% escalation for the water cost.

2.2.8 Utility Interruptions

The utility interconnections are described in detail in Section 2.2.3. It is anticipated that
these connections will be made with minimal interruption to SRS functions. Any necessary
interruption will be coordinated and scheduled in advance with site personnel.

2.2.9 Agency Support Required

Ameresco will continue to work with the Government as the project moves through the final
design and the construction period. Support from the Government’s engineering, contracting, and
maintenance units, as well as management will be required for continued success of the proposed
project.

3.0 ENVIRONMENTAL IMPACT OVERVIEW

By utilizing on and off site biomass sources (rather than coal and fuel oil) to produce steam
and energy, the proposed ECMs will provide a positive impact the environment. However, since both
ECMs introduce new equipment and structures onto the site/area, assessments and permits are
necessary in order to comply with the applicable local, state, and federal requirements. The
positive impacts and benefits of the project are highlighted in Section 3.1. Section 3.2 describes
the environmental permitting required by the SCDHEC and other required environmental documents.

3.1 Overview of Environmental Benefits

	 	•	 	The proposed plants will decrease the overall air emissions rates for 1)
particulate matter (PM) by more than 400 tons a year, 2) nitrogen oxides (NOx) by more than
2,500 tons a year, and 3) Sulfur Dioxide (SOx) by more than 3,500 tons a year. This will
result in a positive impact to the air quality of the local area.
	 
	 	•	 	Both ECMs will reduce energy consumption by eliminating over 6 miles of steam
distribution lines (3.5 miles for ECM 1 and 2.5 miles for ECM 2). The reduced steam
distribution pipe will decrease fuel consumption by at least 10% from reduction of in-line
steam losses.
	 
	 	•	 	The proposed cogeneration facility will decrease the amount of river water
currently drawn from the Savannah River by over 1,412,000 kgal per year. This is
especially significant as the level of the Savannah River is low and this project will
support efforts to protect the water level.
	 
	 	•	 	By replacing fossil fuels with a renewable energy fuel source, green house gas
emissions will be reduced by at least 100,000 tons a year significantly decreasing the
carbon footprint of the SRS.
	 
	 	•	 	Although cogeneration facility and heating plants are not practical feasible
buildings for Leadership in Energy and Environmental Design (LEED) certifications, both
ECMs will incorporate sustainable design methods and incorporate energy efficient
technologies into the design.

3.2 Overview of Environmental Permitting & Assessment

Since the proposed projects will be located at a new site and/or require the installation of
new equipment there will be new emission sources for air, water, and waste water. The resulting
emissions require environmental permits through the Environmental Protection Agency (EPA), SCDHEC,
and SRS. The following table is a summary of the permits required for the project, the status of
the permit, and the expected issuance of the permit. Each of these is further described in the
paragraphs below. The schedule and proposal are based on the dates in the table; significant deviation of these dates
could potentially delay construction. Ameresco will have responsibility for maintaining compliance
with the permits through the construction period and the contract performance period.

of the proposed facility for the criteria air pollutants at expected load and at plant
capacity. Annual potential air emissions are typically calculated based on the potential to emit,
which is defined as the emissions for continuous operation at maximum system capacity. The maximum
capacity would be if the boilers are operated at the full load of 120,000 lbs/hr for 8,760 hours.

NPDES Permit

The proposed outfall for ECM 1 will be included as part of the SRS NPDES Permit. The modification
to site permit was submitted to the site for approval this past month; it is expected to be
incorporated into the Site permit by March 2009. For ECM 2, the K Area boiler blowdown will
discharge into the K Area Ash Basin, as opposed to being discharged to an NPDES outfall. The NPDES
outfall L-07 was modified to include boiler blowdown discharges for the L Area Biomass Heating
Plant. As part of the Memorandum of Understanding/Memorandum of Agreement (MOU/MOA) between
Ameresco and M&O Contractor, language will be incorporated to require Ameresco to retain
responsibility for compliance of the cogeneration facility outfall and for the K and L Area heating
plant effluents.

Storm Water Management Permit

The storm water management prevention plan is currently being developed. Once this plan is
submitted, the permit application will be submitted to the M&O Contractor staff for approval. It
is expected it will be approved within 30 days of submittal.

NEPA

Under the National Environmental Policy Act (NEPA), any modification to a federal facility or site
requires determination of the environmental impact of the proposed change or new process. This
requires issuance of a CATEX (categorical exclusion), development of an environmental assessment
(EA) to determine finding of no significant impact (FONSI), or development of an environmental
impact statement. During the DES phase, the EA was developed to include both proposed ECMs. The
document has been placed for public review. The FONSI was issued in July of 2008.

Annually, Ameresco will complete an M&V report for the project following a visit to the site
and an analysis of system performance. During the annual site visit, Ameresco staff will collect
the monthly performance/operational data, determine the actual fuel use and costs, and then provide
report of the output of each of the sites. Further, monthly reports will be made available to SRS
which include total steam production from each system and fuel usage. Monthly reports will also
include electrical production parameters in addition to steam.

As stated in the individual ECM description sections, annual savings will be based on the avoided
baseline energy and operations and maintenance costs for the existing plants. Therefore, the
annual savings amount is pre-determined for each year of the contract term and will only change
with annual escalation or a mutually agreed upon baseline adjustment, as the existing plants will no longer
operate once the new biomass plants become operational. The annual avoided baseline energy and
operations and

maintenance costs for the existing plants are deemed to have been met upon acceptance of the
ECMs by the Government.

Annual performance requirements are satisfied if, for ECM 1 the ASG is met, and if for ECM 2 each
of the heating plants is operated during the heating season as required to meet the Availability
Guarantee.

If Ameresco is able to produce more steam than the ASG in any given year from the cogeneration
plant, the Government may receive such additional steam for power generation or for thermal use.
If the Government requires and Ameresco is able to produce more than 33,300 klbs in any given year
from the total of both the K and L Area heating plants, the Government may receive such excess
steam for additional thermal use. To the extent the actual steam production exceeds the ASG, the
Government will compensate Ameresco for the additional fuel consumption as proposed pursuant to
Section 1.3.1.2.

4.3 Whole Project Data / Global Assumptions

4.3.1 Risk and Responsibility

Ameresco will be responsible for project construction including the installation, testing, and
commissioning of the equipment to deliver a complete and usable facility. Subsequent to
construction, Ameresco will be responsible for ongoing operations and maintenance of the equipment
installed under ECM 1 and ECM 2. Additionally, Ameresco will provide annual M&V reconciliation
services and an annual M&V report which will include documentation of infrastructure and material
condition, and a summary of equipment performance for the previous performance period.

The risk and responsibility of the Measurement and Verification activities for this project are
addressed in the Risk/Responsibility Matrix in Section 5.4 of this proposal.

4.3.2 Energy, Water, and Operations and Maintenance (O&M) Rate Data

Utility Rates

The energy costs (rates) used to develop the baseline annual cost for ECMs 1 and 2 were provided by
SRS based on historical costs. Annual savings were calculated using the current unit cost and for
coal and fuel oil and the baseline consumption data as described in Sections 1.2.7 and 2.2.7.
Post-ECM implementation non fuel utility costs required for operation of the cogeneration facility
and of the heating plants were factored into the savings at the following previously agreed upon
unit costs as shown in the following table:

Performance Period Rate Adjustment Factors

For both ECMs, the annual energy rates used for savings calculations were adjusted using the latest
escalation factors available from the 2008 National Institute of Standards & Technology (NIST).
The applicable NIST escalation rates are shown in Table 4.3 below. O&M cost savings and the
performance period O&M cost use an annual escalation factor of 3%.

4.3.3 Schedule & Reporting for Verification Activities

The modified BAMF Super Energy Savings Performance Contract (ESPC) requires Ameresco to submit
to the Government a post-installation report, and thereafter, an annual M&V report documenting
equipment performance. Ameresco will follow the Federal Energy Management Program (FEMP)
guidelines in generating these reports. The post-installation report will be submitted to the
Government within 60 days following notification of an ECM’s substantial completion and beneficial
use as given by

Ameresco. The performance period report will be submitted each year within 120 days following
the anniversary date of the ECMs substantial completion date.

4.3.4 Status of Utility Company Incentives

There are no known incentives through the utility company for any of the ECMs in this proposal.

4.4 ECM-Specific M&V Plan and Savings Calculation Methods

4.4.1 Overview of ECM Specific M&V Plans

A specific M&V plan based on DOE FEMP Guidelines and the IPMVP for Measurement and
Verification activities during the term of the contract is described for both ECMs in the following
paragraphs.

4.4.1.1 ECM 1: Biomass Cogeneration Facility

M&V Overview

Option B – ECM Isolation will be used for verification of the performance of ECM 1. Option B
focuses [**] of this ECM. [**], the performance criteria are satisfied. Annual M&V activities
will include [**]. The M&V report will include [**]. The report will also identify the [**].
Further, the M&V report will also include documentation showing [**].

4.4.1.2 ECM 2: Biomass Heating Plants for K& L Areas

M&V Overview

Option B will be used for [**] of ECM 2. Option B focuses on [**]. Annual M&V activities will
include an [**]. The M&V report will include [**] to the K and L Areas.

4.4.2 Energy and Water Baseline Development

Refer to the summaries of savings calculations in Sections 1.7 and 2.7 of this proposal.

4.4.3 Proposed Energy & Water Savings Calculations and Methodology

Refer to the summaries of savings calculation in Sections 1.7 and 2.7 of this proposal.

4.4.4 Operations and Maintenance Cost Savings

The K Area plant is operated by SRS personnel and the D Area plant operations are
subcontracted by the M&O Contractor to a subsidiary company. Both ECMs will result in the shutdown
of an existing plant and eliminate the operation and maintenance expenses required for these sites.
Therefore, SRS will realize an annual savings of $[**] of O&M costs for ECM 1 and $[**] of O&M
costs for ECM 2 during the first year of the contract performance period. The O&M cost savings have been escalated at a
previously agreed upon rate of [**] % per year the contract term.

5.0 Management Approach

5.1 Integrated Management Review Team (IMRT)

Ameresco’s Initial Proposal recommended establishing an Integrated Management Review Team
(IMRT) made up of senior managers from both the Government and Ameresco. While there have been
frequent meetings, conference calls, and project reviews, it is strongly recommended that the IMRT
be activated (in some form) immediately following contract award. As we progress with finalizing
the engineering details and begin mobilizing for construction, the IMRT will be a valuable asset
for promptly resolving any serious challenges that may arise and ensuring that SRS executive level
managers are fully cognizant of project status at all times. It is further recommended the IMRT be
chaired by the Director of the Infrastructure Support & Oversight Division or his designee. The
primary mission of the IMRT will be to assure that appropriate management personnel from each
organization are aware of the project status, informed of key milestones, and if necessary,
involved in securing project approvals.

It is recommended that IMRT membership consists of key personnel from each of the four
organizations participating in the project – DOE SRS, DOE Headquarters, the site M&O contractor
staff, and Ameresco. A proposed IMRT organizational chart, designating team member organizations,
is included as Figure 5.1. The IMRT should be established immediately and convene at least
quarterly throughout the implementation and operations phases to assure senior management is
informed, issues resolved, and decisions are rendered timely.

5.2 Ameresco Management Approach

Ameresco will be responsible for the design, construction, and operation of both ECMs as
included in this proposal. This includes the responsibility for the management of design, quality
control, safety, construction, and operation. Ameresco’s management approach is outlined into
following sections and includes the key strategies listed below:

	 	•	 	Design in accordance with applicable industry codes and design standards for industrial
heating plants and power plants (Refer to Appendix D for list of standards) and in
accordance with the electrical standards, fire protection standards and stacking lighting
standards provided by Government.
	 
	 	•	 	Design documents will be issued to the Government for review and final concurrence
intermittently throughout the first year of the construction period.
	 
	 	•	 	Acceptance of changes to the approved design requested by the government is at the
discretion of Ameresco.

	 	Contract DE-AM36-02NT41457

	 	•	 	Ameresco is the responsible authority for the job sites of the proposed ECMs. This
includes authority for site management, safety enforcement, document control, quality
control, receipt and acceptance of project deliveries, and construction procurement.
	 
	 	•	 	Ameresco will be responsible for document control management including review and
approval of all construction submittals. Ameresco will make electronic copies of major
construction submittals available to government representatives upon request.

Project Implementation Phase (Construction)

Ameresco’s approach to managing the implementation (construction phase) of the proposed measures
will be to assign a fully competent management staff at the construction site and give them the
resources and authority to complete our contract obligations safely, timely, and in a professional
manner. Each member of the on-site management team, headed by the Site Manager, will have the
authority to make project decisions commensurate with their position. Key members of the site
project management team include the Site Manager who will also be the Senior Construction Manager,
Project Construction Manager (engineering subcontractor representative), Job Superintendent, Site
Safety Manager, and Project Documentation Manager. We are currently recruiting, interviewing, and
identifying personnel for most site management positions. However, the Site Safety Manager was
identified early in the DES phase and has been involved with the project for some time. Mr.
Clinton Sandmel will manage the safety program during the construction phase and has interacted
with the SRS Safety Office in completing the project safety analyses and plans, as well as
overseeing the safety efforts of the geotechnical subcontractor. He is an experienced safety
manager and also has experience managing construction safety programs at DOE installations. Mr.
Sandmel and other members of the project management team will be relocated (if not already in the
local area) to the Aiken/Augusta area for the 30 month construction period mitigating travel and
per diem expenses.

Construction subcontractors are being recruited and interviewed from the local area as well as on a
regional and national basis. Ameresco will attempt to maximize the use of local contractor firms
in an effort to support the local economy and mitigate mobilization and travel costs associated
with using subcontractors from outside the local area. Of course, the construction subcontractors
will be key to successful project implementation, and qualifications and price are both
considerations in subcontractor selection. Each subcontractor will provide a project foreman and
safety and quality control personnel. A detailed plan for completing the implementation phase is
included in Section 5.2.6 below.

The site project team will have all the resources necessary to ensure project success available,
including the support of corporate resources from anywhere within the Ameresco organization from
anywhere in North America beginning with the Ameresco corporate staff. While most construction and
project administration activities will be accomplished by the onsite staff, contract
administration, accounting, subcontract administration, and project legal counsel will be
self-performed by division or corporate staff.
Technical oversight of engineering, construction management, and safety will also be accomplished
by the corporate resources.

Operations Phase (Contract Performance Period Services)

Once construction is complete and the Government accepts the project as operational and the
Contract Performance Period begins, the Ameresco staff will shift from implementation to operations
using primarily an onsite staff of Ameresco managers, technicians, and support personnel
supplemented as necessary by subcontractors and other personnel from within Ameresco’s corporate
resources. The cogeneration facility will operate, and be staffed, 24 hours a days, 7 days a week,
365 days a year while the K and L Area plants, although not staffed, will operate 24 hours a day, 7
days a week during the winter heating season.

The Site Operations Manager will lead all facets of ECM operations. This person has not been
determined at this time; however, it is anticipated they will be in place (at the project location)
well before testing and commissioning begins. Key members of the operations staff will be the
Plant Manager, Safety/Environmental Manager, Fuel Procurement Manager, and the Office Manager.
Although we continue to recruit, and have interested candidates, none of the operations staff
managers have been identified at this time. Also, maintenance personnel and plant operators
currently working at the D Area plant will be given an opportunity to join the Ameresco team at the
new cogeneration facility. All site operations and maintenance personnel will reside in the local
community eliminating travel and per diem expenses. Detailed plans for operating the cogeneration
facility and heating plants are included in Section 5.2.7 below.

To the maximum extent practical, project implementation and subsequent plant operations will be
performed under the watchful eye of the skilled and experienced leadership of the onsite management
team; however, the onsite project team will have the full support and backing of additional
corporate resources as necessary.

5.2.1 Ameresco Corporate Management Team

Ameresco’s corporate management team from the ESCO Selection Interview, Initial Proposal, and
Detailed Energy Survey remains intact and will continue to direct, facilitate, and coordinate
Ameresco’s activities into the construction and subsequent operational phase of the biomass ESPC.
Safety and Risk Management have already been added to the corporate team and other additions,
including the Site Manager and Site Operations Manager, will be added at the appropriate time. Mr.
Keith Derrington, Vice President and General Manager will continue as the senior corporate
executive ultimately responsible for assuring success of Ameresco’s Savannah River activities.

An organizational chart depicting the composition of the Ameresco project team is included as
Figure 5.2.

5.2.2 Program Manager

Mr. Joe Price will continue as Program Manager, although much of the interaction and interface
that he previously facilitated with the DOE and M&O staffs will be transferred to the Site Manager
during construction and ultimately to the Site Operations Manager once the ECMs become operational. Mr. Price reports to Mr. Derrington and has overall responsibility for Ameresco’s contract
performance and client relationships at SRS. The Program Manager will also lead Ameresco’s
representation to the IMRT, most likely through the implementation phase before passing that
responsibility to the permanent Site Operations Manager, although no decision has been made on that
at this time.

5.2.3 Engineering

Ms. Nicole Bulgarino will continue as Ameresco’s Lead Project Engineer for the cogeneration
facility and the heating plants and will represent the engineering and environmental activities at
the IMRT. Ms. Bulgarino is responsible for project engineering and design, as well as the subsequent
construction and performance period services. Responsibility for performance period services
including equipment performance issues and annual M&V activities will also fall under purview of
the Engineering Team but will be accomplished by the site operations staff.

5.2.4 Business Operations

Mr. James Koulovatos, Ameresco’s Director of Finance, leads the offices within the business
operations group. Responsibilities of those offices to support the cogeneration facility and
heating plant projects include accounting, contracting, financing, etc. Pending contract award,
Mr. Koulovatos’ staff will manage the development of competitive financing bid packages, work with
3rd party lenders to secure financing for the program, and prepare the final DO
Schedules and Termination Liability Schedule once financing is secured and the interest rate is
locked. Contractual activities include day to day contract administration functions and accounting
will maintain invoicing and accounts receivables ledgers.

5.2.5 Safety and Risk Management

Mr. Kenneth Gross, Ameresco’s Director of Safety and Risk Management, has overall
responsibility for the company’s safety program. Site or project safety personnel will report
directly to Mr. Gross who has been involved with the development of the Worker Health and Safety
Plan (WSHP) to ensure compliance with 10 CRF 851 requirements.

5.2.5.1 Site Safety Management

The Site Safety Manager (SSM) will report to the Director of Safety & Risk Management and is
charged with ensuring the safety of the entire job site. The SSM, Mr. Clinton Sandmel,
participated in development of the WSHP and the associated Job Hazard Analyses (JHA). The SSM is charged with
ensuring that contractor and subcontractor personnel compliance with all applicable safety
regulations. In carrying out site safety duties, the SSM will conduct safety (toolbox) meetings
and inspections and complete the required periodic reports. The SSM will immediately report unsafe
conditions and safety

incidents to the DOE Facility Representatives and the Ameresco Site Manager, Director of
Safety and Risk Management, and the SRS Program Manager.

5.2.6 Construction

As Director of Construction, Mr. Bo Harkness oversees all construction activities within the
federal business unit. The Site Manager, who reports to Mr. Harkness, will be charged with the
day-to-day site management responsibilities during the project implementation phase. Mr. Harkness
will work hand-in-hand with the Program Manager and Lead Engineer to ensure quality construction
completed on schedule and on budget. The Site Manager will also be the on-site point of contact
for SRS/ M&O personnel during the construction phase.

5.2.6.1 Subcontract Management

Onsite construction work will be subcontracted to companies from all parts of the country.
The Director of Construction and Subcontract Administrator will manage all subcontracts, while the
project Site Manager and project Job Superintendent will execute and oversee the subcontracts,
having authority to schedule, inspect, and accept subcontractor work. The Subcontract
Administrator or Director of Construction will respond to any financial or contract management
issues. Invoicing and payments to subcontractors will be handled through standard accounting
procedures and using American Institute of Architects (AIA) contract formats and forms.

5.2.6.2 Construction Management

The Site Manager will be charged with the day-to-day site management responsibilities during
the project construction phase and is tasked with overall responsibility for job site activities.
The Site Manager will also be the on-site point of contact for DOE Facility Representatives and
other SRS/ M&O personnel during the construction phase. Assisted by other Construction Managers
and Job Superintendent personnel, the Site Manager will lead all aspects of project construction
including scheduling, coordination, construction, commissioning, and contract closeout with the
strictest adherence to safety, quality, and cost control procedures.

Project Quality Control (QC) is the responsibility of everyone involved in project activities;
however, ultimate responsibility for the Ameresco QC program rests with the Director of
Construction. Those responsibilities are delegated to the site Quality Control Manager (QCM) who
is tasked to oversee project specific QC activities. The Site Manager or Job Superintendent may be
delegated as the site QCM overseeing the QC activities of all QC personnel, Ameresco and
subcontractors, or a dedicated QCM may be assigned to the project team reporting to the Site
Manager or Job Superintendent.

The site QCM is responsible for individual project quality control. The QCM maintains the Project
Submittal, Testing, and Inspection Logs. The QCM will ensure that project documents (submittals,
shop drawings, reports, etc.) are complete, accurate, and processed in a timely manner. The QCM is also
charged with ensuring testing and inspections are conducted properly and in a manner that will
insure

accuracy. If necessary, the QCM will contract with specialty/professional testing companies
(i.e. concrete tests and welding x-rays).

Ameresco employs the standard Army Corp of Engineers three-phase quality control process that
includes the preparatory phase, initial phase, and follow-up phase. The preparatory phase is
performed prior to each definable work feature. Actions such as reviewing the drawings and
specifications, checking submittal status, and examining the work area, including a hazard
analysis, are done at this time. The initial phase is performed at the beginning of each definable
work feature. Preliminary work is inspected to insure compliance with the contract, establish the
level of workmanship, and ensure compliance with the safety plan. The follow-up phase is ongoing
during performance of work to ensure compliance with contract requirements, perform testing, and
ensure correction of deficiencies.

5.2.7 Site Operations

Once the ECMs are accepted by the government the project will transition to the site
operations phases, which will continue for the remainder of the delivery order performance term.
It is anticipated the cogeneration facility will be staffed with 20 people whose scope of
responsibilities will include the Biomass Cogeneration Facility and the K and L Area heating
plants.

Ameresco intends to have a Site Operations Manager that will oversee the total operation from fuel
procurement and delivery to plant operations and maintenance. The Site Operations Manager has not
yet been identified; however, we have already received inquiries and resumes from interested
parties.

Ameresco will use reasonable diligence to provide a regular and uninterrupted supply of steam (100%
reliability) to the government-owned distribution systems, but shall not be liable for any damages,
losses, costs, or expenses to the government for failure, suspension, diminution, or other
variations of service occasioned by or in consequence of any cause beyond the control of Ameresco,
including but not limited to acts or omissions of the Government and its agents and contractors,
force majeure conditions e.g. acts of the public enemy, acts of God, fires, floods, earthquakes,
etc., or failure or breakdown of the Government-owned distribution system or end-user facilities.

5.2.7.1 Operations and Maintenance Responsibilities

Ameresco will perform the following operations and maintenance of the equipment and facilities
installed within the Biomass Cogeneration Facility under ECM 1 and for the heating plants installed
in the K and L Areas under ECM 2 for the duration of the contract performance period.

	 	•	 	Equipment, instrumentation and control systems installed at the Biomass
Cogeneration Facility

Maintenance Overview

Ameresco will perform the following:

	 	•	 	Operations including materials and consumables for the cogeneration facility
and heating plants, such as costs for the chemicals, urea, diesel fuel, fuel oil, turbine
filter, lube oil, and ash disposal.
	 
	 	•	 	Preventive maintenance includes change out of parts, boiler inspection,
boiler cleaning, turbine oil/filter changes, DA tank inspection, pump servicing, grinder
and hogger inspection, instrumentation calibration, engine testing, HVAC servicing,
building upkeep, Old Burma Road repair, and other service as recommended by equipment
suppliers.
	 
	 	•	 	Unscheduled maintenance includes cost for service and repair not planned on as
part of ongoing maintenance. This mainly consists of contracted service support.

5.2.7.2 Repair & Replacement Responsibilities

The repair and replacement annual expense includes the annual costs expected for the
replacement of materials such as grinder teeth, baghouse filters, sand (bed material) for both
boilers, spare part inventory, and limestone replacement for SOx reduction. These costs will occur
every year regardless of the age of the plant. The repair and replacement costs also include costs
expected to occur for ongoing replacement and repair of boiler in bed tubes, turbine parts, motor
bearings, conveyor belts, and general plant repair fund.

Repair and replacement of the equipment and systems for both ECMs as defined above includes
budgeting and funding an inventory of spare parts, as well as funding and completing minor and
major repairs and equipment replacements. Major repairs and replacements include boiler tubes,
turbine seals, combustor refractory, combustion fans, feedwater pumps, grinders, and augers.
Examples of minor replacements include minor components such as thermocouples, grinder cutters,
instrumentation, motors, motor bearings, filters, chains, and auger components, etc.

5.3 ECM Training

An ongoing O&M Training and Safety Program will be a necessity and training will be provided
to the personnel working at the three sites on a scheduled and recurring basis. Maintaining
training and certification current and in good standing will be required of all personnel. The
training program will also include training with suppliers to ensure the operators are familiar
with the equipment operation and maintenance requirements.

5.4 Risk/Responsibility Matrix

The following pages contain the ESPC Contract Risk/Responsibility Matrix.

RISK/RESPONSIBILITY MATRIX

	 	 	 	 	 
	RESPONSIBILITY/DESCRIPTION	 	AMERESCO’S PROPOSED APPROACH	 	DOE-SR ASSESSMENT
	1. FINANCIAL:
	 	 	 	 
	a. Interest rates:
Neither the Contractor
nor the agency has
significant control over
prevailing interest
rates. During all phases
of the project, interest
rates will change with
market conditions.
Higher interest rates
will increase project
cost, financing/project
term, or both. The timing
of the Contract award may
impact the available
interest rate and project
cost.

	 	Ameresco has included
preliminary interest rate
information in Schedule
DO-3. The interest rate
shown is indicative of the
financial market at the
time of this Revised Final
Proposal and is provided
for information purposes
only. 

Once locked with
Ameresco’s lender, the
interest rate will remain
fixed for the term of the
contract, thereby providing
the DOE-SR with protection
against increased interest
charges resulting from a
variable rate.
	 	In 6.10 of the
Revised Final
Proposal, the
DOE-SR agrees,
among other things,
to not withhold,
reduce, or setoff
the “TOTAL DEBT
SERVICE” amount on
Schedule DO-3 in
the event of an
Ameresco default.
The reason for this
is to provide
assurance to
Ameresco’s lender
that its investment
is secure.

The
DOE-SR expects the
Ameresco to obtain
the lowest possible
interest rate and
will competitively
seek financing from
several financial
institutions. The
DOE-SR expects, as
consideration for
6.10, that Ameresco
will obtain a lower
interest rate than
the one indicated
in the Final
Proposal, dated
December 8, 2008.
	 
	b. Energy prices:
Neither the
Contractor nor the
agency has
significant control
over actual energy
prices. For
calculating
savings, the value
of the saved energy
may either be
constant, change at
a fixed inflation
rate, or float with
market conditions.
If the value
changes with the
market, falling
energy prices place
the Contractor at
risk of failing to
meet cost savings
guarantees. If
energy prices rise,
there is a small
risk to the agency
that energy

	 	The D Area plant that is
being replaced by the
Biomass Cogeneration
Facility is fueled by coal
purchased from SCE&G.
Ameresco proposes to
establish the
pre-installation baseline
for ECMs 1 and 2 based on
the consumption and cost
information provided by SRS
and M&O Ameresco personnel.
The baseline costs are
escalated at 2008 published
NIST rates for each year of
the performance period. 

The
energy savings for all ECMs
are calculated based
	 	The rates used to
establish the
energy baseline are
different than what
has been included
in DOE HQ’s
database, Energy
Management System
4. Based on the
unprecedented
increases in coal
costs over the
previous year, the
baseline costs
associated with
coal will come from
SRS’s current
one-year coal
contract for the
D-Area Powerhouse,
which took effect

	saving goals might
not be met while
the financial goals
are. If the value
of saved energy is
fixed (either
constant or
escalated), the
agency risks making
payments in excess
of actual energy
cost savings.
Clarify how future
energy costs will
be treated.

	 	on the reduced fuel costs
associated with improved
system efficiencies. To
determine this reduction,
the following items are
predetermined for
establishing the
pre-installation baseline:
the unit cost of fuel oil
and coal, and the amount of
energy produced by the
existing D Area and K Area
plants.

The
pre-installation baseline
data used in this proposal
consists of cost and
consumption data for a 24
month period as provided by
SRS and M&O personnel for
ECM 1, and 5 years of data
was used to develop the
baseline for ECM 2. The
future cost of each of
these utilities has been
escalated by the applicable
NIST factors for each year
throughout the contract
term.

 Ameresco proposes
the DOE-SR assume
responsibility for the
actual unit cost of
utilities (i.e.
electricity, coal, water,
etc.) including any
escalation or
de-escalation. If at any
time during the term of
this contract, the ECMs do
not create sufficient
savings on an annual basis
to fund the amount due
Ameresco for reasons within
SRS’ control or for reasons
related to changes in unit
price of utilities, then
SRS will pay Ameresco as
agreed or renegotiate the
payment schedule and term
in a form mutually
agreeable to both parties
and Ameresco’s lender such
that the outstanding
balance of contract
payments is fully repaid.

Ameresco proposes to assume
responsibility for biomass
procurement and has
estimated the price of
biomass based on current
local market conditions
escalated at [**]% per
year.
	 	November 1, 2008.
Based on market
research, coal is
not expected to
decrease in cost
based on current
and world demand.
In addition, SRS’s
electrical rates
have also increased
dramatically over
the last two years
based on the
increased costs of
coal and natural
gas that the Site’s
electrical supplier
must recoup through
its electric rates
that have been
approved by the
South Carolina
Public Service
Commission. These
baseline rates will
be escalated in
accordance with
NIST standards.

Throughout the
performance period,
Ameresco will be
supplied utilities
at no cost but the
consumption data
will be metered and
supplied to the
Site’s utility
department to be
included in
calculating the
true cost of
generating steam
and/or electricity
from the new
biomass plants for
inclusion in Site
supplied utilities.

	c. Construction costs:
The Contractor is
responsible for
determining construction
costs and defining a
budget. In a fixed-price
design/build Contract,
the agency assumes little
responsibility for cost
overruns. However, if
construction estimates
are significantly greater
than originally assumed,
the Contractor may find
that the project or
measure is no longer
viable and drop it before
Contract award. In any
design/build Contract,
the agency loses some
design control. Clarify
design standards and the
design approval process
(including changes) and
how costs will be
reviewed.

	 	A significant portion of
Ameresco’s business is
focused on energy
engineering, design and
consulting. Ameresco
staff, complemented by
subcontracted experts, are
developing the ECM designs
for this proposal.
Additionally, Ameresco’s
in-house construction
management team has
collaborated extensively
with the design team,
potential subcontractors,
and equipment suppliers to
assure project
constructability, review
budgeted costs, and provide
insight into procurement
options. Having all these
functions involved
throughout the DES Phase
substantially lowers the
risk of construction cost
overruns, and ensures a
realistic and balanced
approach to innovation and
realism in project design. 

To manage the risk
associated with escalating
prices for construction
materials and equipment,
Ameresco will hold material
and labor pricing set forth
in Schedule DO 2 included
herein through May 15,
2009. The proposal
acceptance period may be
extended; however, there
may be changes in project
pricing. The parties will
share the risk of
construction cost increases
that occur prior to
contract award; however,
Ameresco will assume sole
responsibility for cost
increases occurring in
normal market conditions
after contract award as
well as responsibility for
managing the risks of such
increases. However, should
cost increases be caused by
extraordinary market
conditions, the parties
will negotiate changes to
the construction completion
schedule and/or financial
terms of the contract as
mutually agreeable to both
parties.
	 	Upon submittal of
the Revised Final
Proposal, a Cost
Reasonableness
Review of
Ameresco’s
Implementation
Costs will be
performed.
Ameresco shall
submit a breakdown
of the
Implementation
costs with the
Revised Final
Proposal to allow
the DOE-SR to
perform the review.

	 	Design-build will be the
means of project
implementation, and the
proposed project will be
designed and constructed to
meet industry and those
local SRS standards
identified in this
proposal, and included with
the contract award. 

The cost of the DES as
shown on the DO-2 schedule
includes the following:

contract award and in
accordance with a delivery
schedule mutually agreed
upon by the DOE-SR and

Following resolution of any
review comments, a final
set of record documents
will be produced and
delivered to the DOE-SR.

	 	 
	 

	 	Once final concurrence is
obtained, the design and
project specifications
become the basis for
construction and no further

	d. M&V costs: The agency
assumes the financial
responsibility for M&V
costs directly or through
the Contractor. If the
agency wishes to reduce
M&V cost, it may do so by
accepting less rigorous
M&V activities with more
uncertainty in the
savings estimates.
Clarify how project
savings are being
verified (e.g. equipment
performance, operational
factors, energy use) and
the impact on M&V costs.

	 	Ameresco proposes that M&V
Option B – ECM Isolation be
used to verify the
performance of ECM 1 and
ECM 2. Project performance
will be continuously
metered and reported to the
DOE-SR on a monthly basis.
The metering equipment
installed for the project,
in combination with the
established baseline energy
costs and NIST-based annual
adjustments, will provide
sufficient M&V of project
performance without
unnecessarily increasing
project costs. Section 4.4
describes the M&V plan in
detail. 

Performance Period M&V
costs are escalated
annually at a fixed rate of
[**]%.
	 	The DOE-SR concurs
with the M&V
approach for the
project.
	 
	e. Non-Energy Cost
Savings: The agency and
the ESCO may agree that
the project will include
savings from recurring
and/or one-time costs.
This may include one-time
savings from avoided
expenditures for projects
that were appropriated
but will no longer be
necessary. Including
one-time cost savings
before the money has been
appropriated entails some
risk to the agency.
Recurring savings
generally result from
reduced O&M expenses or
reduced water
consumption. These O&M
and water savings must be
based on actual spending
reductions. Clarify
sources of non-energy
cost savings and how they
will be verified.

	 	Both proposed ECMs will
result in the shutdown of
existing DOE-SR operated
plants eliminating
significant O&M expenses
currently incurred by SRS.
The O&M cost baseline is
presented for each ECM and
was developed based on
information, and is
collaborative effort
between Ameresco, SRS and
M&O technical personnel. 

The annual O&M savings have
been escalated annually at
a fixed rate of [**]%.

NOTE: There will be a
significant reduction in
the consumption of water
taken from the Savannah
River, although no cost
savings related to such
reduction in water usage
have been included in this
proposal.
	 	The DOE-SR has
provided actual O&M
costs for both the
D-Area Powerhouse
and the K-Area
Package Boilers.
The DOE-SR will
review such costs
included in the
Revised Final
Proposal and, if
acceptable,
provide its
concurrence.

	f. Delays: Both the
Contractor and the agency
can cause delays.
Failure to implement a
viable project in a
timely manner costs the
agency in the form of
lost savings, and can add
cost to the project
(e.g., construction
interest,
remobilization). Clarify
schedule and how delays
will be handled.

	 	Ameresco will fully support
the DOE-SR during the
review, approval, and award
of the proposed ECMs to
mitigate potential delays
as much as is within
Ameresco’s control.
Further, Ameresco will
honor the pricing proposed
herein through May 15,
2009; delays in contract
award beyond that time may
result in increased project
cost and will result in
project implementation
delays.

Major milestones for
obtaining project
approvals, delivery order
award, and project
implementation are
indentified in Table 1.7
herein. Ameresco will
provide a detailed project
schedule subsequent to
contract award reflecting
the scheduled completion
date for each major element
of ECM 1 and 2. The
schedule will be closely
monitored throughout the
construction phase by
Ameresco’s on-site
management team as well as
corporate management. Their
proactive involvement will
mitigate the occurrence of
delays. Should a delay
occur, Ameresco management
will immediately develop a
mitigation plan, discuss it
with the DOE-SR staff, and
then take the necessary
actions to ensure the
project remains on
schedule.

will work with
Ameresco to
facilitate a smooth

	 	actions will be taken by
Ameresco management personnel if
necessary. The schedule is being
structured both logically and
realistically to minimize the
potential for delays; however,
should an unavoidable delay occur,
Ameresco will work closely with
DOE-SR engineers to determine the
best course of action and, if
necessary, a revised schedule will
be developed and proposed. The
primary objective of any revision
will be to get the work back on
track without extending the
completion date.	 	 
	 
	 	 	 	 
	 

	 	Subcontractor Management

Ameresco has pre-qualified many
firms and will continue to
pre-qualify firms that may be
selected as subcontractors.
However, Ameresco will continue to
evaluate qualifications and the
firm’s current workload prior to
executing any subcontracts. If
manpower later becomes an issue,
Ameresco will either direct the
firm to hire additional personnel,
hire additional subcontractors, or
replace the subcontractor. 

Ameresco will manage subcontractors
and suppliers through close control
and monitoring of all critical
activities. Monitoring and
controls include the following
procedures: weekly progress
meetings, schedule updates, and
materials management plan.	 	 
	 
	 	 	 	 
	 

	 	Late Delivery of Materials/Equipment 

In order to protect against late
delivery of material or equipment
and keep the project on schedule,
Ameresco will implement and
maintain a materials management
plan and constantly monitor
production and delivery dates.

	g. Major changes in facility:
The agency (or Congress)
controls major changes in
facility use, including
closure. Clarify
responsibilities in the event
of a premature facility
closure, loss of funding, or
other major change.

	 	The SRS is not considered a
candidate for closure at any time
in the foreseeable future. Based
on information provided by SRS
personnel, a build-up in operations
is projected to continue past 2020.
The electrical and steam demand
are projected to change in future
years, but it is assumed (almost
certain) that the site will be a
viable entity throughout the
contract term and well beyond.

The structure of the proposed
project significantly reduces risk
associated with changes at the
site. Ameresco will be producing
steam that will provide two
benefits to the DOE-SR; steam for
thermal processes and electricity.
Should changes at the facility
result in reduced thermal
requirements, Ameresco will produce
more electricity. The first
priority will be to satisfy the
site’s steam needs. Should there
be excess capacity (delta between
guaranteed steam production and
site steam requirements) the steam
will be processed through a turbine
to produce electricity. The
versatility of the process to
satisfy both thermal and electrical
needs of the site mitigates this
risk.
	 	The DOE-SR concurs
with Ameresco’s
projection of the
longevity of SRS
operations. If a
termination were
necessary, the DOE
Contracting Officer
and Ameresco would
proceed utilizing
the applicable
Federal Acquisition
Regulation (FAR)
and Department of
Energy Acquisition
Regulation (DEAR)
requirements.
	 
	 	 	 	 
	 

	 	Ameresco has assessed the potential
for closure of the site and
considers it a minimal risk at this
time. However, if SRS should close
or experience a significant
reduction, then Ameresco will be
responsible for characterizing and
quantifying the impact of the
changes on the project. In a

	2. OPERATIONAL:
	 	 	 	 
	 
	 	 	 	 
	a. Operating hours: The
agency generally has control
over the operating hours.
Increases and decreases in
operating hours can show up as
increases or decreases in
“savings” depending on the M&V
method (e.g. operating hours
multiplied by improved
efficiency of equipment vs.
whole building/utility bill
analysis). Clarify whether
operating hours are to be
measured or stipulated and
what the impact will be if
they change. If the operating
hours are stipulated, the
baseline should be carefully
documented and agreed to by
both parties.

	 	Operating hours of the proposed
cogeneration facility and heating
plants have been pre-determined.
The operating hours of SRS
facilities obtaining service from
the Ameresco plants (i.e., steam
and/or electricity) were also
determined for purposes of
establishing baseline consumption
data, but will have little to no
impact on the operations of the
proposed ECMs unless increased
operating hours contributes to the
site requiring more steam than
provided by the ASG.

ECM 1, the cogeneration facility
(replacing existing D Area plant)
shall operate 24/7 year round and
ECM 2, the K and L Area plants will
operate 24/7 as necessary over
approximately a four month period
each year to meet building heating
loads. Although operating hours
are pre-determined, steam delivery
requirements will be both
pre-determined and measured.
	 	The DOE-SR concurs
with this approach
since the ASG will
not be dependent on
facility operating
hours. Excess
steam above the
customer
requirements will
be dispatched for
electrical
generation.
	 
	 	 	 	 
	 

	 	Over the past two years, SRS’
energy consumption has been
relatively consistent in
conjunction with the operating
hours. Therefore, the energy

	 	guarantees assume
predetermined operating hours for
the term of the delivery order;
however, Ameresco will guarantee an
annual quantity of steam production
that will not be impacted by
changes to facility operating
hours.	 	 
	 
	 	 	 	 
	 

	 	The DOE-SR will control and be
responsible for its increasing or
decreasing facility operating
hours.	 	 
	 
	 	 	 	 
	b. Load: Equipment loads can
change over time. The agency
generally has control over
hours of operation,
conditioned floor area,
intensity of use (e.g. changes
in occupancy or level of
automation). Changes in load
can show up as increases or
decreases in “savings”
depending on the M&V method.
Clarify whether equipment
loads are to be measured or
stipulated and what the impact
will be if they change. If
the equipment loads are
stipulated, the baseline
should be carefully documented
and agreed to by both parties.

	 	The overall site steam load is
expected to decrease in the out
years of the contract performance
period. Ameresco and DOE-SR
personnel worked closely during the
DES phase to construct a model of
out year steam requirements to
accommodate the decreases. Project
performance calculations are based
on load projections shown in Table
1.1, which were provided by site
personnel and are assumed by
Ameresco to be correct. Decreasing
steam requirements will be
accommodated by increasing net
green power generation. Increasing
steam requirements above ASG
(excess production) will be
accommodated up to the maximum
plant capacity. Compensation for
the excess steam production will be
included in the annual cost
adjustment.
	 	The DOE-SR agrees
with Ameresco’s
proposed approach.
Additional steam
requested by the
DOE-SR above the
ASG will be
compensated for at
Ameresco’s
incremental biomass
expense with a
mutually negotiated
markup.
	 
	 	 	 	 
	 

	 	It is proposed that the DOE-SR and
Ameresco share the risk of
increased load requirements.
Ameresco will assume responsibility
for providing the steam to meet
increased loads up to the maximum
plant capacity. However, Ameresco
will be compensated for steam
deliveries above the guaranteed
annual production quantities as
provided for by the fuel adjustment provision found in Section 1.3.1.2
of this proposal.

RISK/RESPONSIBILITY MATRIX

	 	 	 	 	 
	RESPONSIBILITY/DESCRIPTION	 	AMERESCO’S PROPOSED APPROACH	 	DOE-SR ASSESSMENT
	c. Weather: A number of
energy efficiency measures are
affected by weather. Neither
the Contractor nor the agency
has control over the weather.
Changes in weather can
increase or decrease “savings”
depending on the M&V method
(e.g. equipment run hours
multiplied by efficiency
improvement vs. whole building
utility bill analysis). If
weather is “normalized,”
actual savings could be less
than payments for a given
year, but will average out
over the long run. Clearly
specify how weather
corrections will be performed.

	 	Neither Ameresco nor the DOE-SR has
control over the weather and
changes in weather can increase or
decrease the amount of steam needed
by SRS facilities. However, the
metric for determining whether
Ameresco has satisfied its
performance guarantees are not
weather dependent; therefore,
weather corrections are not be
necessary. Ameresco proposes that
no weather corrections be made as
neither ECM will be significantly
impacted by the weather since the
baseline has been developed from
historical consumption data.

NOTE: Although weather could
impact the amount of steam needed
for heating purposes, that risk has
been addressed by increased
electrical generation as outlined
in paragraph b above.
	 	The DOE-SR agrees
with Ameresco’s
proposed approach.
	 
	 	 	 	 
	d. User participation: Many
energy conservation measures
require user participation to
generate savings (e.g. control
settings). The savings can be
variable and the Contractor
may be unwilling to invest in
these measures. Clarify what
degree of user participation
is needed and utilize
monitoring and training to
mitigate risk. If performance
is stipulated, document and
review assumptions carefully
and consider M & V to confirm
the capacity to save (e.g.
confirm that the controls are
functioning properly).

	 	Ameresco will operate and maintain
the systems proposed under both
ECMs as defined in Section 5.2.7.1.
The ECMs will interconnect with
site utility distribution systems
that will be maintained by the site
M&O Contractor, as is currently the
case. The DOE-SR will be the end
user of the steam produced by the
Ameresco plants. The Government
must accept steam deliveries and
the site M&O contractor must ensure
utility services are available for
the ECMs to be effective. The risk
of either the DOE-SR not accepting
steam deliveries (within the
baseline amounts) or the utility
systems being down over prolonged
period of time is minimal.
	 	The DOE-SR
agrees with
Ameresco’s proposed
approach.

	RESPONSIBILITY/DESCRIPTION	 	AMERESCO’S PROPOSED APPROACH	 	DOE-SR ASSESSMENT
	3. PERFORMANCE:
	 	 	 	 
	 
	 	 	 	 
	a. Equipment performance:
Generally the Contractor has
control over the selection of
equipment and is responsible
for its proper installation,
commissioning, and
performance. Generally the
Contractor has responsibility
to demonstrate that the new
improvements meet expected
performance levels including
specified equipment capacity,
standards of service, and
efficiency. Clarify who is
responsible for initial and
long-term performance, how it
will be verified, and what
will be done if performance
does not meet expectations.

	 	Ameresco will retain responsibility
for the performance of the
equipment throughout the term of
the performance period for both
ECMs as defined in Section 5.2.7.1.
Ameresco has experience and is
familiar with the equipment. It
selected the equipment based upon
efficiency, performance level, and
reliability, and in conjunction
with the manufacturer’s service and
performance guarantees.
Performance of the equipment will
be reflected in the annual M&V
documentation provided by Ameresco.
	 	The DOE-SR agrees
with Ameresco’s
proposed approach.
	 
	 	 	 	 
	b. Operations: Responsibility
for operations is negotiable,
and it can impact performance.
Clarify responsibility for
operations, the implications
of equipment control, how
changes in operating
procedures will be handled,
and how proper operations will
be assured.

	 	Ameresco will retain operations
responsibility and assumes the
risks associated with ECM
operations throughout the contract
term as defined in Section 5.2.7.1.
Proper operations will be assured
by appropriate staffing levels of
the plant by local Ameresco
personnel and/or contracted
employees.

Ameresco site management will
implement and oversee plant
operations to ensure equipment is
operated and maintained to provide
an efficient and safe operation
that satisfies manufacturer and
contract requirements.
	 	The DOE-SR agrees
with the Ameresco’s
proposed approach.
	 
	 	 	 	 
	 

	 	Title to the biomass fuel will pass
to the DOE-SR upon delivery to the
plant site. Should the biomass
fuel become damaged or destroyed
due to the fault or negligence of
Ameresco, then Ameresco shall bear
responsibility for replacing such
damaged biomass fuel.

	 	Otherwise,
DOE-SRS shall be responsible for
any biomass fuel damaged or
destroyed for any other reason.	 	 
	 
	 	 	 	 
	c. Preventive Maintenance:
Responsibility for maintenance
is negotiable, and it can
impact performance. Clarify
how long-term preventative
maintenance will be assured,
especially if the party
responsible for long-term
performance is not responsible
for maintenance (e.g.,
Contractor provides
maintenance checklist and
reporting frequency). Clarify
who is responsible for
long-term preventive
maintenance to maintain
operational performance
throughout the Contract term.
Clarify what will be done if
inadequate preventive
maintenance impacts
performance.

	 	Ameresco assumes responsibility for
all maintenance and repairs of the
equipment installed in the new
facility under the contract term as
defined in Section 5.2.7.1.
This includes a preventative
maintenance program, incidental
repairs, and warranty work.
Ameresco will verify performance of
the maintenance on an on-going
basis, with an in-depth review of
the maintenance program conducted
during annual performance
reconciliation. The ongoing costs
of operations and maintenance for
the equipment is included in the
performance period expenses and
escalated annually at [**]% for the
duration of the performance period.
	 	The DOE-SR agrees
with Ameresco’s
proposed approach.
	 
	 	 	 	 
	d. Equipment Repair and
Replacement: Responsibility
for repair and replacement of
Contractor-installed equipment
is negotiable; however it is
often tied to project
performance. Clarify who is
responsible for the
replacement of failed
components or equipment
throughout the term of the
Contract. Specifically
address potential impacts on
performance due to equipment
failure. Specify expected
equipment life and warranties
for all installed equipment.
Discuss replacement
responsibility when equipment
life is shorter than the term
of the Contract.

	 	Ameresco will assume responsibility
for the repair and/or replacement
of failed components and equipment
throughout the term of the contract
as specified in Section 5.2.7.2
except for such damaged or
destroyed ECM equipment for which
the DOE-SR self-insures pursuant to
Section 6.5 of the Revised Final
Proposal.
	 	As part of the
Performance Period
expenses, Ameresco
has included, and
is clearly
responsible for,
all Repair &
Replacement
functions. Only
Ameresco-installed
equipment that is
damaged or
destroyed for
reasons beyond the
control and without
the fault or
negligence of
Ameresco, may
result in
consideration as
noted in Section
6.5 of the Revised
Final Proposal.

	 	Contract DE-AM36-02NT41457

	6.0	 	PROPOSAL PRICING INFORMATION

Schedules DO-1 through DO-5(a) (the “DO—Schedules”) presented at the end of this section
provide the economic and financial details of the proposed project based on SRS making annual debt
service payments at the beginning of each performance period and monthly performance period
expenses.

In addition to price quotes and estimates provided by suppliers and vendors, price estimates were
developed using Ameresco software cost models, historical project cost data, and cost estimating
guides (e.g. RS Means, etc.).

	6.1	 	Interest Rate

Ameresco’s locked interest rate of 8.19% as shown on Schedule DO-3 is based on Moody’s AA
Corporate Index, as published by Bloomberg on May 12, 2009, of 6.14% plus a spread above the Index
of 2.05%.

	6.2	 	Finance Procurement Price

The finance procurement price set forth on Schedule DO-3 consists of the following three
components and will fluctuate until the project interest rate mentioned above is fixed:

	 	a)	 	Performance/Payment Bond — Performance and payment bonds are a requirement
of the Contract. The performance bond is purchased by Ameresco to protect the
Government and the third party lender against Ameresco non-performance during the
implementation period. The performance bond applies only to the installation portion
of the work under this contract and does not apply in any way to energy savings
guarantees, payments or maintenance provisions, except that the performance bond shall
guarantee that the installation will be free of defective materials and workmanship
for a period of twelve (12) months following completion and acceptance of the work.
Ameresco’s lender will require the execution a Dual-Obligee Rider naming such lender
as an additional or dual-obligee under the performance bond.
	 
	 	b)	 	Interest During Construction (“IDC”) — This cost represents the
interest costs accruing to Ameresco during the proposed implementation period.
Ameresco’s DO-Schedules assume a traditional upfront funding of the Total Amount
Financed into an interest bearing escrow account upon award of the contract,
Ameresco will be charged interest on the amount funded at the project interest rate and will net these interest charges with interest
earnings on the escrow account’s remaining principal balance. Ameresco will receive
progress payments

	Ameresco Federal Solutions
	 	Savannah River Site
	Page 87
	 	Contract DE-AM36-02NT41457

	 	 	 	for implementation expenses from the escrow account. In addition to the traditional
escrow funding approach, Ameresco is exploring a delayed funding structure in lieu of
the traditional escrow funding structure proposed herein. Under the delayed funding
structure, Ameresco’s lender will advance progress payments to Ameresco periodically
during the construction period. Interest will begin to accrue only on the progress
payments made to Ameresco and accrued interest will negatively amortize the outstanding
balance. Ameresco believes if it is able to utilize the delayed funding structure it
will provide significant savings on interest during construction.

	 	c)	 	Finance Processing Fee — The finance processing fee represents expenses
Ameresco will incur to finance the contract. Typically, this fee is a combination of
the following applicable expenses: legal fees, origination fees, fees for rating
agencies, rate lock fees to fix the interest rate during the implementation period,
trustee or fiscal agent fees, and any rate buydown costs.

	6.3	 	Sales Tax

Ameresco intends to pursue a sales tax exemption with the South Carolina Department of Revenue
(“SCDOR”) with respect to the ECM equipment pursuant to S.C. Code Ann. section 12-36-2120(29).
This exemption provides the following sales are exempt from sales tax: “tangible personal property
purchased by persons under a written contract with the federal government when the contract
necessitating the purchase provides that title and possession of the property is to transfer from
the contractor to the federal government at the time of purchase or after the time of purchase.
This exemption also applies to purchases of tangible personal property which becomes part of real
or personal property owned by the federal government or, as provided in the written contract, is to
transfer to the federal government. This exemption does not apply to purchases of tangible
personal property used or consumed by the purchaser.” The SCDOR also issued South Carolina Revenue
Ruling No. 04-9, which outlines the requirements for contractors to qualify for the exemption
contained in S.C. Code Ann. section 12-36-2120(29). For the contractor’s purchases to be exempt
from sales tax, the contractor must have a written contract with the federal government which
provides that title and possession of the property is to transfer from the contractor to the
federal government at the time of purchase or after the time of purchase and such title and
possession actually transfers to the federal government in accordance with the contract or the
property becomes part of a real or personal property owned by the federal government or is to
transfer to the federal government.

Ameresco must obtain an exemption certificate issued by the SCDOR to purchase tangible personal
property exempt from sales tax. Ameresco will submit an application (S.C. Form ST-10G) together
with a copy of the executed contract to obtain the required exemption certificate. Due to the fact
that Ameresco will not receive an exemption certificate until after contract award is executed,
Ameresco has included a sales tax reserve in its proposal in the approximate amount of $4,600,000.
Should Ameresco receive an exemption certificate, Ameresco will request that its lender deposit the
sales tax reserve into the PPEF upon the Government’s acceptance of the ECMs. Ameresco proposes to
wait until acceptance

to fund the PPEF with the sales tax reserve to avoid paying interest on such reserve during the
construction period. To the extent that Ameresco is denied an exemption certificate by the SCDOR,
Ameresco will notify the Government of such determination and the sales tax reserve shall be
dispersed to Ameresco by its lender via progress payments.

	6.4	 	Property Tax

Title to all contractor-installed equipment associated with each ECM shall vest in the
Government. Therefore, the Government is the owner of all contractor-installed equipment for
property tax purposes and Ameresco has not included property taxes in this proposal. In the event
the Government elects not to accept title to the contractor-installed equipment, Ameresco would
need to revise this proposal to include all applicable property taxes.

	6.5	 	Insurance

Ameresco will maintain builder’s risk insurance coverage on all contractor-installed equipment
during the implementation period. Ameresco’s proposal does not include any cost related to
insuring any contractor-installed equipment post-acceptance. Title to all equipment installed by
Ameresco shall be vested with the Government after acceptance by the Government of the commercial
operation of such ECM and the Government will self-insure all such Contractor-installed equipment
throughout the Delivery Order term for the Total Amount Financed as shown on Schedule DO-3. This
acceptance shall not relieve Ameresco’s responsibility for ECM performance. Ameresco will be
responsible for operating and maintaining all ECMs throughout the contract term as set forth
herein. If such Ameresco-installed equipment is damaged or destroyed, for reasons beyond the
control and without the fault or negligence of Ameresco, the Government shall have the option to
(i) terminate the Delivery Order (either in part or in whole) and hold Ameresco harmless for the
savings and performance associated with the damaged or destroyed equipment for the remainder of the
term, (ii) pay Ameresco, by separate contract action to repair or replace the damaged or destroyed
equipment and continue making its scheduled payments to Ameresco, or (iii) repair or replace the
damaged or destroyed equipment at its cost and continue making its scheduled payments to the
Ameresco. If the repair/replacement work is performed by any party other than Ameresco, a
commissioning of the repair/replacement work must be conducted, witnessed and approved by both the
Government and Ameresco. This requirement is necessary for Ameresco to continue to guarantee the
related energy savings as set herein.

	6.6	 	Payment/Term

Ameresco will submit its initial invoice for payment with respect to an ECM upon the earlier
of (i) completion of the ECM and acceptance by the Government or (ii) when the Government has
beneficial use of such ECM. Following the initial invoice submittals by Ameresco, Ameresco will
invoice the Government on or before the first day of April each year thereafter such that the
Government’s annual

Debt Service payment will be paid annually on or before the first day of May. Performance Period
Expenses will be paid monthly on the first day of each month in an amount equal to one-twelfth
(1/12) of the Total Performance Period Expenses due for each Performance Period.
Submission of or revisions to the Post Installation Completion Report, As-Built drawings, or
O&M Manuals, or delays in providing training that do not affect savings, shall not delay acceptance
with respect to the commencement of making payments to Ameresco, but will be noted as punch list
items and addressed by Ameresco in a timely manner. Ameresco is proposing annual debt service
payments be made at the beginning of each performance period because it reduces the principal
balance the fastest and results in the lowest interest expense to the Government. The annual debt
service period will occur and payment will be due prior to Ameresco’s submission of the applicable
year’s Annual M&V Report. However, any shortfall in Annual Savings set forth in such report will
be adjusted from future performance period payments as provided in Section G.4 of the BAMF
Contract. Payments from the government will be applied first to prompt payment interest, then to
performance period expenses, then to interest and then to principal.

	6.7	 	Cancellation/Termination/Buyout

Schedule DO-5(a) — Termination Liability Schedule is provided with this proposal in addition
to Schedule DO-5. Schedule DO-5(a) provides an amortization of the project’s outstanding principal
balance along with the calculation used to determine the Termination Liability and is provided for
use in the event that the Government prepays or terminates the project for its convenience.
Schedule DO-5(a) represents Ameresco and its third-party lender’s recovery of allowable contract
expenditures, and associated profit, incurred as of the date of termination or buyout and assumes
all payments are received by Ameresco (or its assignee) when due. The column titled “Outstanding
Principal Balance” represents Ameresco’s recovery of costs associated with the installation work in
connection with implementing the ECMs. The column titled “Lender’s Termination Premium” over the
original project cost represents the third-party lender’s immediate recovery of administrative,
placement, legal, and investment banking expenses associated with the original financing as well as
its termination. These financing costs are not represented in the project cost as a line item, but
are built into the interest rate spread and recovered over time as debt service. If Schedule
DO-5(a) only reflected the project costs, Ameresco’s third party lender would fail to recover their
allowable contract expenses and associated profit in the event of a termination or buyout. The
lender’s termination premium is a cost recovery alternative that the third-party lender must rely
on in the event of a termination or buyout in lieu of amortizing fees and costs over time.

In the event of a termination for convenience in whole, cancellation in whole, or prepayment in
whole, the Government acknowledges and agrees that it shall be obligated to pay the specific
Termination Liability amount set forth on Schedule DO-5(a) for the month corresponding to the
effective date the Government intends to make payment to Ameresco. In the event of a termination
for convenience in part, cancellation in part or reduction in requirements in part, the Government
acknowledges and agrees that Ameresco shall apply any such payment made by the Government to the
Outstanding Balance and Lender’s Termination Premium amounts set forth on Schedule DO-5(a)
corresponding to the effective date of such payment in part. Following the application of such
payment in part, the Government will enter into a contract

modification to incorporate a revised Schedule DO-5(a) reflecting, at the Government’s option, a
reduction in the total number of payments or reduction in amount per payment over the remaining
term such that, in either case, the Outstanding Principal Balance is fully repaid. In the event of
a prepayment or buydown, the Government acknowledges and agrees that Ameresco shall apply any such
payment made by the Government as set forth in Section 6.8 below.

Any termination for convenience of the Performance Period portion of the contract shall be handled
in accordance with FAR 52.249-2.

	6.8	 	Prepayments/Buydowns

In the event the Government chooses to make prepayments or buydowns during the performance
period of the contract term, with the purpose of reducing the outstanding unamortized balance of
the financing for the ECMs, and thereby reducing the price/payments and overall term of the
contract, the following method shall be used to apply those prepayments to the delivery order
price:

The prepayment amount will be placed by the third-party financier into an account to be identified
in the prepayment modification to the delivery order, to be reinvested at a fixed rate, and at
which rate the amount shall earn and accrue interest, for the shorter of (a) the remaining term of
the delivery order, as revised by delivery order modification of the award Schedules at the time of
any prepayment; or (b) the period up to the date the delivery order may be terminated by the
Government. Determination of the fixed rate at which the prepayment amount shall earn and accrue
interest shall be by mutual agreement of the parties based on then-current reinvestment rates. The
sum of (i) the prepayment amount and (ii) projected accrued interest shall be the total amount
applied against the remaining delivery order payments, as reflected in the task order, in reverse
order of the scheduled contract payments. Thereby, the scheduled term of the contract shall be
reduced, and the payment schedule revised and overall price reduced, as reflected in a revised
schedule incorporated into the contract by modification. A revised schedule will also be provided
and incorporated into the delivery order award by modification. This process may be repeated to
incorporate subsequent prepayments.

	6.9	 	Protection of Financier’s Interest

All cure or show-cause notices or notices of default will be mailed by the Government to
Ameresco’s assignee, as set forth in the Notice of Assignment delivered to the Contracting Officer,
at least 15 days in advance of any termination of this contract for default. The Government will
consider requests by such assignee to extend the applicable cure or show-cause response period so
long as such cure is being diligently pursued.

	6.10	 	Security Interest in ECM Equipment

During the implementation period and prior to title to the ECM equipment vesting in the
Government, the Government agrees to subordinate any security interest it may have in any Ameresco
installed ECM equipment to Ameresco’s lender, and grants such lender a first priority security
interest in the ECM equipment. Upon the Government’s acceptance of each ECM, Ameresco will cause
its lender to release its security interest in such ECM equipment and to deliver evidence of such
to the Contracting Officer.

	6.11	 	Assignment of Claims

Pursuant to DOE FAR subpart 932.803 Policies, Ameresco proposes to finance the ECMs through an
assignment of the Government’s payments under the contract awarded in connection with this proposal
in compliance with FAR 52.232-23 Assignment of Claims, Alternate I (Apr 1984). Ameresco or its
lender will remit to the Government the required Notice of Assignment together with the Instrument
of Assignment. The Government agrees to acknowledge receipt of such notice and incorporate such
assignment in a contract modification.

	6.12 	 	Title to and Responsibility for Contractor-Installed Property

The Government acknowledges that, with respect to the ECMs, the Government is obligated to
accept delivery thereof pursuant to the contract upon satisfaction of the conditions thereto.
After acceptance by the Government of the installed ECMs and vesting of title with the Government
to the equipment installed by Ameresco, the Government agrees that there shall be no withholding,
reduction or setoff by the Government in the payment of the specific amounts as set forth in the
row labeled “TOTAL DEBT SERVICE” on Schedule DO-3 as a result of (i) any termination for default,
in whole or in part, pursuant to FAR Clause 52.249-8 (Default-Fixed Price Supply and Service) by
the Government of the Performance Period (as defined in Modification M005 to Contract No.
DE-AM36-02NT41457, Section J, Attachment 1) portion of the contract, or (ii) any costs assessed
against Ameresco pursuant to FAR Clause 52.246-4 (Inspection of Services-Fixed Price).

In the event of any termination for default, in whole, of the Performance Period portion of the
contract, the Government may elect to, but in no way is obligated or required to, buyout the
Ameresco installed equipment by paying the sum of the columns labeled “Outstanding Principal

BIOMASS COGENERATION FACILITY

SUBSURFACE EXPLORATION

SAVANNAH RIVER SITE

QORE JOB NO. U1629, REPORT NO. 36127

1.0 INTRODUCTION

1.1 General

QORE, Inc. has completed a subsurface exploration for the referenced project in accordance with our
proposal Number 02777 dated February 6, 2008 which was revised by proposal 02777R dated February
29, 2008. The purposes of this exploration were to assess subsurface conditions at the site and
provide recommendations for foundation design for the anticipated structures, for seismic design
considerations, and for earthwork considerations that should be taken into account during
subsequent project planning. Project information was provided through the Soil Boring Location Plan
of the site prepared by Ameresco Federal Solutions dated 7, Jan. 2008 and “Bore Map with Boring
Locations” plan (undated) prepared by Lynn Mourning of Savannah River Site, our meeting of January
30, 2008 with Ms. Nicole Bulgarino, P.E., Mr. Kenneth W. Gross, and Mr. Joseph T. Price of
Ameresco, and Mr. Ross W. Hill, P.E. of ESI Inc. of Tennessee, and follow-up conversations and
e-mails with Ms. Bulgarino and Mr. Doug Luckett, P.E. of ESI. This report explains our
understanding of the project, documents our findings, and presents our conclusions and engineering
recommendations.

1.2 Report Summary

Our findings are summarized below for convenience. This brief tabulation should not be used solely
for design and planning purposes without first reviewing the more detailed information presented in
the remainder of the report.

	•	 	Fourteen (14) soil test borings, three (3) Seismic Cone Penetrometer Test (SCPT) soundings,
four (4) Cone Penetrometer Test (CPT) soundings, and one hand auger boring were performed to
evaluate the subsurface soil and groundwater conditions at the accessible locations of the
project site.

	•	 	The soil profile consists of natural Coastal Plain soils. Very loose to very firm silty
and clayey sands were encountered across the site. The fines (particles smaller than a #200
sieve) content of the soils ranged from 11% to 29%. The soils generally contained more clay on
the north and

	 	 	east sides of the site. The sand soils encountered in our borings can be used as
a source of structural fill; however, some wetting or drying may be required. Difficult
excavation due to rock will not be encountered during construction.

	•	 	Groundwater was measured in the borings at the time of drilling at 54 feet in boring
B15 and at 85 feet and 88 feet in SCPT 15a and 19, respectively. Permanent groundwater will
likely not be encountered; however, perched groundwater could develop during periods of rain.

	•	 	Based on our settlement calculations, we estimate that the mat foundation for the main
boiler/turbine building may settle up to 11/2 inch. To reduce settlement, we
recommend densifying the upper loose sand across the site and preloading the building pad with
at least 12 feet of fill. Other structures may be supported by mat foundations with a maximum
allowable bearing stress of 1,500 psf and a maximum horizontal dimension of 35 feet, or spread
footings with a maximum allowable bearing stress of 2,500 psf and a maximum dimension of 10
feet.

• A Site Specific Seismic Assessment was performed and is included in the Appendix.

2.0 PROJECT INFORMATION

The anticipated development of the site consists of the construction of a steel frame building
approximately 118 feet by 193 feet with column spacing of 25 feet to 30 feet which will house two
boilers, an auxiliary boiler, and a turbine generator. The following information was provided via
several telephone conversations with Mr. Doug Luckett, P.E. and his e-mails of March 26 and April
2, 2008. From this information, we understand that a mat is the preferred type of foundation which
will support the building as well as the boilers, generator, and ancillary equipment. The mat, as
now planned, will be approximately 199 feet by 124 feet, and 3 feet thick. The total load on the
mat is anticipated to be 34,418 kips, which results in an average bearing stress of approximately
1.4 kips per square foot. We understand that the allowable vertical deflection across the length of
the boilers and the turbine generator cannot exceed 1/8" each and desired total settlement is less
than 1/2 inch.

Other structures and loads include:

	 	•	 	Two stacks, 5 to 6 feet in diameter and 150 feet high, with loads of 70 kips each will
be supported on separate octagonal foundations.
	 
	 	•	 	A cooling tower with dimensions of approximately 100 feet by 53 feet and a total load
of 411 kips.

 

 

			
	Biomass Cogeneration Facility
	 	April 18, 2006
	QORE Job No. U1629, Report No. 36127
	 	Page 3

	 	•	 	Stacker/reclaimer structure supported by four columns in a square configuration
101/2 feet apart with a total load of approximately 530 kips each.
	 
	 	•	 	Silo with plan dimensions of 26 feet by 14 feet supported by four columns with a
total load of 530 kips each.

The project also includes two bag houses, a cooling tower, conveyor system and maintenance
structure, truck scales, tanks, and screens for which complete details were not provided. This
report is based on the assumption that these structures are relatively lightly loaded (less than
200 kips), and shallow, spread foundations will be adequate. We are not aware of any deep
excavations, high fills, or retaining walls planned for this facility. An access road and parking
area will be provided for automobiles and trucks. The anticipated truck loading is 100 tractor
trailers per day. Cut and fill slopes will be what are necessary to balance the site during
grading. A grading plan was not provided; however, based on our meeting on January 30, 2008, we
anticipate maximum cuts and fills on the order of five to ten feet.

3.0 FIELD EXPLORATION AND TEST METHODS

The geotechnical exploration began with a visual site reconnaissance performed by a member of our
professional staff. Originally, the exploration was planned using 21 soil test borings of varying
depths. Three of the borings were to be extended to a depth of 100 feet within the footprint of the
boiler/generator building, however the first deep boring attempted (B15), encountered heaving sand
at a depth of 70 feet and had to be terminated. As a result of the heaving sand and the fact that
only silty sand was encountered, the scope of work was revised to replace seven of the borings with
Cone Penetration Tests (CPT) and Seismic CPT (SCPT). This allowed for collection of soil data to
the planned depth of 100 feet and provided shear wave velocity data which are better suited for
evaluation of cohesionless soils. Fourteen soil test borings, four Cone Penetration Test (CPT)
soundings, three CPT soundings with seismic shear wave velocity measurements (SCPT), and one hand
auger boring were performed. The original numerical designation for each exploration location on
the undated “Bore Map with Boring Locations” plan remain the same, but the prefix (B, CPT, SCPT,
and A) were changed to indicate the type of exploration. One additional SCPT sounding was added
next to boring B15 and is designated SCPT 15A. The borings and soundings were located, surveyed,
and staked in the field by Savannah River Site Personnel. Unless an offset is indicated, the
borings and soundings were located within 5 feet of the staked position. The boring and sounding
locations are provided on the Exploration Location Plan in the Appendix. The surveyed and provided
horizontal coordinates for each boring location are given on each boring or sounding record.

The procedures used by QORE for field sampling and testing were performed in general accordance
with ASTM procedures and established engineering practice. Standard Penetration

	 	Page 4

tests and split spoon samples were obtained at 2.5 foot intervals in the upper 10 feet and 5 foot intervals
thereafter with the exception of borings B17 and B18, where the samples were obtained at 5 foot
intervals for the entirety of the borehole. A standard 1.4-inch I.D., 2-inch O.D. split-barrel
sampler was used. The sampler was first seated 6 inches and then driven an additional 12 inches
with blows of a 140-pound automated hammer falling 30 inches. The number of hammer blows required
to drive the sampler the additional 12 inches was recorded and is designated the “standard
penetration resistance” with units of blows per foot (bpf).

After completion of the drilling activities, the borings were backfilled with auger cuttings.
Selected borings were left open 24 hours for a groundwater measurement. Soil descriptions, standard
penetration test results, and other subsurface data are presented in the Soil Test Boring Records
in the Appendix.

CPT and SCPT soundings were performed by pushing an electronically instrumented cone shaped probe
into the soil at a rate of approximately two centimeters (0.79 inch) per second with the hydraulic
system of a truck mounted reaction device. The 1.4-inch diameter, 18-inch long cone is equipped
with an instrumented tip and a steel friction sleeve that measures tip resistance and soil-to-steel
friction, respectively, as the cone is being pushed. The cone is equipped with a pore pressure
transducer that records the pore water pressure in the soil as the cone is advanced. The cone is
also instrumented with geophones that allow for the measurement of shear wave velocities at depth.
Shear wave velocities were measured at intervals of 1 meter. The CPT and SCPT plots and a more
detailed procedure for the CPT are included in the Appendix.

One boring, B3 was located in dense woodlands, inaccessible to our equipment. The boring was
completed by hand auger and Dynamic Cone Penetrometer (DCP) to a depth of 7 1/2 feet at
which point the soil was to firm to continue.

At our laboratory, the recovered soil samples were visually classified by our geotechnical
professional. Samples were selected for index testing consisting of grain size analysis, Atterberg
limits, California Bearing Ratio (CBR), Resistivity, and pH. The laboratory test results are
contained in the Appendix.

4.0 SITE AND SUBSURFACE CONDITIONS

4.1 Existing Site Conditions

The project site is approximately 60 acres located on the northwest side of Berma Road,
approximately  1/2 mile from C Road on the Savannah River Site. According to the
information provided, this area appears to be previously undeveloped. The site slopes moderately
from north to south with a relief of approximately 12 feet across the main building footprint. The
section of land

	QORE Job No. U1629, Report No. 36127
	 	Page 5

that will house the proposed the boiler building, cooling tower, biofuel storage
silos, and stacks was logged about five years previously and is covered with young trees and brush.
The section of the site that will house the proposed stacker/reclaimer, truck scales, dumpsters,
and disc screen and hogger has not been cleared and contains mature forest.

4.2 Geology

The site is located in the Coastal Plain Physiographic Province of South Carolina. The Coastal
Plain is a wedge-shaped deposit of Cretaceous and younger sediments that range in thickness from
near zero at the contact with the Piedmont Physiographic Province (the Fall Line) along its
northwest edge, to thousands of feet at the coast. Coastal Plain soils are marine deposits laid
down in the geologic past when ocean levels were higher, and can contain various materials
including interbedded soft and hard limestones, gravel, sands, silts, and clays, as well as
organics.

4.3 General Soil Profile

The borings within the proposed boiler/generator building, stacks, and cooling tower footprints (B9
through B18 and B21) generally encountered about 6 inches of topsoil and loose multi-colored silty
sand with alternating zones of loose and firm silty sand to their varying termination depths of 35
to 70 feet below the existing ground surface (bgs). Penetration resistances ranged from 3 to 33
blows per foot (bpf). The fines (particles smaller than a #200 sieve) contents ranged from 11% to
29%. Borings B9 and B10 also encountered very firm silty sand at depths of 23 feet to 28 feet and 6
feet to 13 feet, respectively, with penetration resistances of 21 to 24 bpf. Boring B15 encountered
penetration resistances of 27 to 33 bpf from a depth of 631⁄2 feet to 70 feet. An additional SCPT
sounding (designated SCPT 15A) was offset from boring B15 approximately 5 feet north and met
refusal at a depth of 16 feet. It was offset approximately 5 feet in the other direction and
extended to the planned termination depth of 100 feet. Except for B17, the borings also encountered
varying amounts of very loose (resistance ≤ 4 bpf) silty sand and sand with silt within the
upper 10 feet.

Seismic cone penetrometer tests SCPT15A, SCPT19, and SCPT20 encountered soil conditions consistent
with the borings previously described, as far as the borings extended. SCPT 19 and SCPT15A
encountered dense sand with tip resistance greater than 20 MPa at depths of approximately 53 feet
to 63 feet and approximately 63 feet to 73 feet respectively. SCPT20 encountered refusal on clean
sand at a depth of 66 feet and was terminated. SCPT15A encountered relatively soft clay and silty
clay with tip resistance less than 5 MPa at approximate depths of 75 to 77 feet and 82 to 89 feet.
SCPT19 encountered relatively soft clay and silty clay

 

 

			
	Biomass Cogeneration Facility

	QORE Job No. U1629, Report No. 36127
	 	Page 6

with tip resistance less than 5 MPa at
approximate depths of 68 to 72 feet and 76 to 81 feet. Shear wave velocities were measured in each
of these soundings at intervals of one meter. The shear wave velocities measured, were generally
over 1000 feet per second (fps). In SCPT 15A, the mean velocity measured was 1170 fps with a
minimum of 800 fps at a depth of 87.2 feet, and a maximum of 1843 fps at a depth of 11.8 feet. In
SCPT 19, the mean velocity measured was 1134 fps with a minimum of 850 fps at a depth of 70.8 feet,
and a maximum of 1397 fps at a depth of 57.7 feet. In SCPT 20, the mean velocity measured was 1010
fps with a minimum of 715 fps at a depth of 24.9 feet, and a maximum of 1489 fps at a depth of 18.4
feet.

The other explorations to the north and east of the area described above, generally encountered
more clayey soils (B6, B7, B11, CPT1, CPT2, CPT4, CPT5 and A3). B6, B7, and CPT4 encountered loose
sands with varying degrees of silt (3-10 bpf) to depths of approximately 2 to 7 feet bgs underlain
by clayey sand (15 to 19 bpf) to depths of approximately 81⁄2 to 10 feet bgs followed by
loose to firm sands with varying concentrations of silt (7 to 20 bpf) to the planned termination
depths. Borings B11, CPT1 and CPT2 encountered very loose to firm sand with varying degrees of silt
to depths of approximately 5 to 18 feet bgs underlain by firm to stiff clayey sands and silty clay
to the planned termination depths. CPT1 encountered very stiff clayey soil to a depth of
approximately 141/2 feet at which point refusal was encountered (planned
termination depth was 15 feet). CPT2 met refusal in clay soil at a depth of approximately
171⁄2 although the planned termination depth was 20 feet. CPT5 met
refusal in clayey soil at a depth of approximately 101⁄2 feet, although the planned termination
depth was 15 feet.

The above discussion is a relatively brief and general description of subsurface conditions
encountered in the borings at the time of our exploration. Detailed descriptions are presented on
the individual Soil Test Boring Records. When reviewing these records, one should recognize that
the indicated boundaries between soil strata are approximate and the transitions between strata are
generally gradual. Also, variations in subsurface conditions from those encountered may exist
intermediate of the boring locations.

4.4 Groundwater

QORE recorded groundwater level measurements at the time of drilling. Groundwater was measured at a
depth of 54 feet bgs in boring B15, approximately 24 hours after completion. Groundwater was
estimated by pore pressure dissipation in SCPT 15 and 19 at 85 and 88 feet bgs,

respectively.
Groundwater levels fluctuate with seasonal and yearly rainfall variations. It is possible that
groundwater may be encountered at a shallower depth than indicated by our measurements.

5.0 LIMITATIONS OF REPORT

This report has been prepared for the exclusive use of the Ameresco Federal Solutions and their
designers for specific application to this project. Our conclusions and recommendations have been
prepared using generally accepted standards of geotechnical engineering practice in the State of
South Carolina. No other warranty is expressed or implied. This company is not responsible for the
conclusions, opinions, or recommendations of others based on these data.

Our conclusions and recommendations are based on the data obtained from the previously described
subsurface exploration and our past experience. They do not reflect variations in the subsurface
conditions, which are likely to exist between our exploration locations and in unexplored areas of
the site. These variations result from the inherent variability of the subsurface conditions in
this geologic region.

If the overall design, location, or elevation of the proposed building is changed, the
recommendations contained in this report must not be considered valid unless the changes are
reviewed by our firm and our recommendations modified or verified in writing. When the design is
finalized, we should be given the opportunity to review the foundation plan, grading plan, and
applicable portions of the project specifications. This review will allow us to check whether these
documents are consistent with the intent of our recommendations.

Field observations, monitoring, and quality assurance testing during earthwork and foundation
installation are an extension of the geotechnical design. We recommend that the owner retain these
services and that we be allowed to continue our involvement in the project through these phases of
construction. Our firm is not responsible for interpretation of the data contained in this report
by others, nor do we accept any responsibility for job-site safety which is the sole responsibility of
the contractor.

Subsequent report sections include comments about excavation, foundation construction, earthwork,
and related geotechnical aspects of the proposed construction. The recommendations contained herein
are not intended to dictate construction methods or sequences. They are based on findings from this
subsurface exploration and are furnished solely to help designers understand

subsurface conditions
related to foundation and earthwork plans and specifications. Depending on the final design of the
project, the recommendations also may be useful to personnel who observe construction activity.

6.0 CONCLUSIONS

	 	•	 	Due to the very loose sand condition of the near surface soils, we recommend densifying
the upper sand with a large vibratory roller. Also, to reduce settlements to within
acceptable levels, the foundation for the boiler/generator will require preloading. After
preloading the site, the main boiler/generator structure can be supported by a mat
foundation with a maximum average contact pressure of 1500 psf.
	 
	 	•	 	The stacks, silo, and stacker/reclaimer building can be supported on mat foundations
placed on natural Coastal Plain soils or properly compacted structural fill, with a maximum
average contact pressure of 1500 psf.
	 
	 	•	 	Other structures, including the hogger, bag house, scales, conveyor, and maintenance
facility can be supported on spread footings placed in firm natural soils or on properly
compacted structural fill and can be sized for an applied bearing stress of 2,500 psf.
	 
	 	•	 	Permanent groundwater should not be encountered within the anticipated
construction excavation depths. However, temporary perched water may be encountered during
extended periods of rainfall.
	 
	 	•	 	Based on the results of our pH (4.6) and resistivity (86,000 W-cm) tests, the soil
sample collected at the site is considered to be highly corrosive.
	 
	 	•	 	We do not anticipate that rock or difficult excavation conditions will be encountered.
	 
	 	•	 	We anticipate that most cut materials will be satisfactory for structural fill,
although some drying or wetting of the fill material will likely be required.

7.0 RECOMMENDATIONS

7.1 General

The following recommendations are based on our geotechnical exploration described above and our
knowledge of the site. In developing our recommendations, mat foundations were considered for the
boiler/generator building, stacks, cooling tower, and silo. Shallow spread footings were considered
for the other structures.

7.2 Site Preparation

Topsoil, organics, stumps, large trees and root systems should be stripped to prepare the site for
construction. After stripping, the site should be observed by a representative of our firm, and any
remaining pockets of organics or large root systems should be undercut and discarded off site or
stockpiled for future use in landscaped areas. Stripping should extend at least 10 feet beyond the
construction limits.

7.3 Excavation and Undercutting

7.3.1 Subgrade Evaluation and Preparation

After designated areas of the site have been stripped and undercut, at-grade areas and areas that
are to receive fill should be evaluated by a member of our staff by observing proofrolling with a
heavily loaded dump truck or earthmoving scraper. Proofrolling consists of applying repeated passes
to the subgrade with this equipment. Any materials judged to deflect excessively under the wheel
loads and which cannot be densified by continued rolling should be undercut to more stable soils
before placing fill. Following evaluation, we recommend densifying the subgrade with a large
vibratory roller with a rated dynamic force of at least 50,000 pounds. This equipment should make
at least six passes across the subgrade (three passes in one direction and three passes
perpendicular to the initial passes).

7.3.2 Groundwater and Excavation Dewatering

From the results of our borings, we anticipate that permanent groundwater will not be encountered
in excavations. Perched groundwater could develop in the upper sand soil during periods of
rainfall. We believe that a combination of gravity-drained ditches connected to the storm water
drainage system and pumped sumps can be used for the anticipated limited depth of dewatering
groundwater.

	 	Page 10

7.4 Earth Material Utilization

We anticipate the majority of the site silty sand and clayey sand soils will be satisfactory for
structural fill material. Select fill will be required to replace any undercut materials found to
be unsatisfactory for structural fill. Structural fill is defined as soil classified as SC, SM,
SP-SC, SP-SM, and SP under the Unified Soils Classification System (USCS) which is free of organics
and deleterious material, exhibits a plasticity index less than 20, has a maximum particle size
less than 3 inches, and is compacted to at least 95 percent of the soil’s maximum dry density as determined by
the standard Proctor compaction test (ASTM D 698). Structural fill should be placed and compacted
in relatively thin (six to eight inch maximum) layers. We recommend that the upper 18 inches of
fill beneath the foundations, floor slabs, and pavements be compacted to at least 98 percent.
Structural fill placement and compaction should be monitored by our qualified geotechnical
personnel on a full time basis to check that the recommended compaction criteria have been
achieved.

7.5 Settlement Provisions

We have made calculations to estimate settlement of the boiler/generator building supported by a
mat foundation of approximately 199 feet by 124 feet and an average bearing stress of 1500 psf. We
also made calculations for smaller mat foundations for the, silo, and cooling tower as well as
shallow spread footings. Based on these assumptions, we estimate that the maximum total settlement
of the boiler/generator building with the existing soil conditions will be on the order of 11⁄2
inch. In order to reduce the calculated maximum settlement to an acceptable level, we recommend
that the site be preloaded. Preloading consists of applying a weight of soil that simulates a
portion of the load applied by the structure and allowing it to remain for some period of time
before grading the site to the foundation elevation. The weight of the soil will induce settlement
to occur before the building is placed. On site soils may be used for the preload and placed in
conjunction with grading other areas of the site.

Based on the size of the building loads, and our subsurface data, we recommend a preload of 12 feet
of soil across the boiler/generator building site. This loading level should reduce final estimated
settlement of the boiler/generator building to a maximum of 1⁄2 inch. The soil should be
left in place until review of monitored settlement data indicates settlement is essentially
complete. We estimate that this will occur within 30 days of completion of the preload, but likely
much quicker.

	QORE Job No. U1629, Report No. 36127
	 	Page 11

After stripping of the site, surface densification, and evaluation by our geotechnical engineer as
described in preceding paragraphs, structural fill should be placed to bring the fill areas to the
foundation bearing elevation. The preload soils should then be placed on the fill and remaining
natural topography. The existing soil that is above the final foundation grade may be considered
when determining the height of the preload, therefore cut areas should be left in place until after
preloading. For example, if the final foundation grade (bottom of the mat foundation) at the east
end of the building is in an area requiring 6 feet of cut, then only an additional 6 feet of
preload will be required in that area. In these areas, the subgrade should be densified as
previously discussed after the pad is cut to grade.

The top elevation of the preload soil should be established a minimum of 12 feet above the final
mat foundation grade (bottom of the mat). We recommend that the crest of the preload be marked and
controlled by survey techniques. The crest of the preload should extend at least 10 feet beyond the
foundation perimeter. Outside slopes should be no steeper than 1.5(H):1(V).

Preload fill can be dumped and spread in as thick of lifts as is practical. It should be compacted
enough to permit operation of equipment for placing subsequent lifts. Periodic in-place density
testing should be performed to determine the average unit weight of the surcharge material. If the
unit weight is less than 100 pounds per cubic foot, some additional compaction may be required. The
fill surface should be sealed at the end of each day’s grading and when the full thickness has been
placed. The final preload surface should be sloped or crowned to facilitate surface drainage. These
procedures are important to limit absorption of rainwater because the preload fill will likely be
reused as structural fill.

Before preloading the area, settlement plates should be installed at the mat foundation subgrade in
three locations along the longitudinal centerline; at the demarcation between cut and fill (point
where the natural ground intersects the foundation grade), and at the maximum points of cut and
fill, but no closer than 30 feet to the end of the mat. The location of these settlement monitoring
devices should be selected by QORE. The settlement plates should be constructed and installed as
follows:

	 	•	 	The settlement plates should consist of 3/8-inch thick steel plates that are 2 feet x
2 feet square.

	QORE Job No. U1629, Report No. 36127
	 	Page 12

	 	•	 	A two-inch diameter, threaded steel riser pipe should be welded perpendicular to
the plate at the center.
	 
	 	•	 	The pipe should be threaded on each end so that additional sections of pipe can be
added using couplings. End caps should be used at the end of the pipe to protect the
threads.
	 
	 	•	 	Each section of riser pipe should be painted with fluorescent orange paint for high
visibility.
	 
	 	•	 	Four steel braces of 2 inches x 1⁄4 inch x 2 feet should be welded to the outer edge of
the base of the settlement plate and attached to the first section of steel pipe for
lateral stability.
	 
	 	•	 	Each settlement plate location should be prepared by leveling the area so that when the
plate is placed on the ground the pipe extends vertically and is plumb. This should be
checked with a carpenter’s level.
	 
	 	•	 	The elevation of the base plate and the top of the pipe cap should be recorded prior to
any filling.
	 
	 	•	 	When filling begins and with the placement of subsequent lifts, soil should be
carefully placed around the settlement plate locations so that a mound of soil is always 2
to 3 feet higher than the fill mass surrounding it. The horizontal radius of the mound
should extend out from the pipe at least 8 feet. Temporary stakes with fluorescent flagging
circling the settlement plate location are recommended for high visibility. This will help
keep heavy equipment from destroying the settlement plates during the placement of fill.
	 
	 	•	 	As the filling proceeds, additional sections of threaded steel riser pipe should
be coupled to the previous section and capped. The elevation of the top of the pipe cap
should be recorded immediately before and immediately after the addition of a new section.

A professional surveyor should establish the vertical and horizontal control required to accurately
locate the settlement plates (and/or settlement monuments) in the field. Surveying will be required
on a daily basis throughout the fill placement and once every two days thereafter to determine the
settlement at each location. The elevation data should be provided to QORE within 24 hours of the
time of collection. The accuracy of the survey for the settlement plates or monuments should be
within +/- 0.01 feet in the vertical direction and +/- 0.5 feet in the horizontal direction.

The waiting period begins when placement of the preload soil, is complete. We anticipate that the
settlement induced by the preload will be substantially complete within approximately 30 days of
placement of the preload. Once the required settlement has occurred, the preload and any required
cut soils can be removed and the foundation subgrade re-compacted and re-evaluated.

7.6 Foundations

7.6.1 Main Boiler/Generator Building

The exploration findings and our evaluation indicate that the main structure can be supported on a
mat foundation after the preloading described above and the subgrade densification have been
accomplished. We recommend a maximum average allowable soil bearing pressure across the mat of 1500
psf. Based on the anticipated size of the mat and the results of our subsurface exploration, we
recommend a modulus of subgrade reaction (ks) of 26 kips per cubic foot or 15 pounds per
cubic inch be used for design of the mat thickness and reinforcement. We recommend that the mat be
designed to withstand a potential differential displacement of 1⁄4 inch across one half of
its width. The mat should be embedded not less than 3 feet below the lowest exterior grade as a
bearing capacity requirement.

7.6.2 Stacks. Silos, Cooling Tower, and Stacker/Reclaimer Building

The exploration findings and our evaluation indicate that the stacks, silo, and stacker/reclaimer
building can be supported on mat foundations placed on natural Coastal Plain soils or properly
compacted structural fill. We estimate maximum settlements of 1⁄2 and 3⁄4 inch
for average bearing pressures of 1000 psf and 1500 psf respectively for mats with a maximum
horizontal dimension of 35 feet. The allowable bearing pressure may be increased by 1/3 at
the edges to resist transient overturning moments. According to information provided, the cooling
tower has dimensions of approximately 100 feet by 53 feet and a total load of 411 kips for which we
estimate maximum settlement of less than 1⁄4 inch.

Based on the anticipated size of the mat and the results of our subsurface exploration, we
recommend a modulus of subgrade reaction (ks) of 26 kips per cubic foot or 15 pounds per
cubic inch be used for design of the mat thickness and reinforcement. These mat foundations should
be embedded not less than 2 feet below the lowest exterior grade as a bearing capacity requirement.

7.6.3 Other Structures

The subsurface exploration results indicate that other miscellaneous structures can be supported on
shallow individual spread footings up to a maximum dimension of 10 feet (except strip footings).
The foundations may be designed for a maximum allowable net soil bearing pressure of 2,500 pounds
per square foot (psf). The foundations should bear in firm Coastal Plain soil or new structural
fill.

	QORE Job No. U1629, Report No. 36127
	 	Page 14

Even though computed footing dimensions may be less; individual footings and strip footings should
be at least 24 inches wide. These dimensions will facilitate hand cleaning of the footing subgrade
and placement of reinforcing steel. These dimensions also reduce the potential for localized
“punching” shear failure. All footing bottoms should bear at least 24 inches below finished floor
level or exterior grade; whichever is lower.

7.6.4 All Foundations

All foundation excavations must be evaluated by a geotechnical engineer from our firm prior to
concrete placement to observe that the exposed soils are consistent with the boring results and the
recommendations already provided. Based on the engineer’s observations during the evaluation, we
may recommend additional densification of the soils and/or additional undercutting. Additional
densification could be accomplished by undercutting the foundation and using the same soil,
provided the soil moisture condition is sufficient to achieve adequate compaction for use as
compacted structural fill to bring the foundation to grade. The mat foundation subgrades should be
densified with a large vibratory roller as previously described. The engineer can also provide
geotechnical guidance should any unforeseen foundation problems develop during construction.

We recommend selectively removing any disturbed or water-softened soils from the foundation
excavations before placing reinforcing steel. Also, foundation subgrade soils will soften if
exposed to weather extremes. If foundation concrete cannot be placed the same day as the excavation
is completed and evaluated, the excavations should be covered with polyethylene sheeting or a thin
concrete “mud mat”. If these protective measures are not implemented, over-excavation of disturbed
soil may be necessary. We recommend budgeting for some undercutting and backfill of foundation
excavations.

7.7 Floor Slabs Other Than Mat Foundations

Building floor slabs can be supported on natural firm Coastal Plain soil or structural fill after
implementation of the previously described site preparation measures. To reduce the possibility of
slab cracking due to minor differential settlement, the floor slab should be structurally separate
from the foundations, or transitions from foundation-supported building elements to soil supported
floors should be reinforced. Since shallow groundwater was not encountered, we believe that an
underslab drainage layer is optional unless moisture-sensitive floor coverings will be used. The
subgrade should, however, be covered by an effective vapor retarded to reduce the possibility of
slab dampness due to soil moisture.

It has been our experience that between completion of grading and slab construction, floor slab
subgrades are often disturbed by weather, footing and utility line installation, and other
construction activities. For this reason, the subgrade should be evaluated by a geotechnical
engineer

	 	Page 15

immediately prior to construction of the slab. During this evaluation, the subgrade should
be proofrolled with relatively heavy rubber-tired equipment. Areas judged by the geotechnical
engineer to perform unacceptably under the moving load should be aerated and compacted, or undercut
and replaced with compacted crushed stone or structural fill as identified in the Structural Fill
section of this report.

7.8 Retaining Walls

We understand that there are no major retaining walls planned for this project. For walls up to six
feet high which act as retaining walls, which are laterally restrained and not free to deflect or
rotate, we recommend that they be designed using the “at-rest” earth pressure condition. Where
retaining walls are free to deflect or rotate, they may be designed for the “active” earth pressure
condition.

Soils behind the retaining walls are assumed to exert a triangular stress distribution which can be
modeled in terms of an “equivalent fluid” for both the active and at-rest cases. If a uniform area
surcharge is applied behind the wall, a portion of the surcharge is transferred to the wall in the
form of a uniform or rectangular lateral stress distribution. The magnitude of the lateral stress
transferred to the wall is a function of the soil’s strength and the permissible degree of
deflection or rotation. It is computed by multiplying the soil’s “earth pressure coefficient” by
the magnitude of the surcharge.

For point loads (such as a truck) within a horizontal distance to the wall less than the wall’s
height, the following equation may be used:

êsh = 0.48Qx2z/R5

Where R = (x2+y2+z2)1/2

êsh = the horizontal stress increase from surcharge load Q at the surface, at some
distance x from the wall.

z = the depth below the top of the wall to the point to where the stress is applied.

y = the length along the wall beyond the centerline of load application to where the stress is being applied.

The following table contains values of earth pressure coefficients and equivalent fluid unit
weights for both the active and at-rest earth pressure conditions for horizontal fill behind the
walls.

	 	 	 	 	 	 	 	 	 
	 	 	 	 	 	 	Recommended Equivalent
	Earth Pressure Condition	 	Earth Pressure Coefficient	 	Fluid Unit Weight, pcf
	Active, Horizontal Backfill
	 	 	0.33	 	 	 	40	 
	At-Rest, Horizontal Backfill
	 	 	0.50	 	 	 	60

	 	Page 16

Passive earth pressure of soil adjacent to the foundation as well as soil friction at the
foundation base may be used to resist sliding. The ultimate friction coefficient between the
concrete foundation and soil can be assumed to be 0.30. For computations, the ultimate passive soil
resistance may be assumed to act as a fluid with an equivalent unit weight of 345 pcf above the
water table.

In computing soil friction at the foundation base, compacted soil placed above the foundation can
be assumed to have a unit weight of 115 pounds per cubic foot. We recommend that a safety factor of
2 or more be used when computing restraining forces.

The recommended earth pressure coefficients assume the ground surfaces on both sides of the walls
are level. The recommended equivalent fluid pressures also assume that wall backfill will be
compacted structurally as previously discussed, that constantly functioning drainage systems are
installed between walls and soil backfill to prevent the build-up of hydrostatic pressures.

Wall drainage systems should consist of a filtered granular backfill (No. 57 size crushed stone) or
a manufactured material such as Enkadrain or Miradrain. The drainage media should extend to within
2 feet of the ground surface. Compacted structural fill should be placed over the drainage media to
prevent direct surface water inflow. In paved areas, the media may extend to the base material. The
drainage media should be connected to a positive drainage system, preferably gravity. If crushed
stone drainage media are used, we recommend that it be separated from the surrounding soil by a
non-woven geotextile filter cloth such as Mirafi 140NS.

The previously recommended soil parameters are “average” values based on our experience. Triaxial
shear tests and standard Proctor compaction tests of soils in this geologic region indicate that
there could be a potential scatter of ± 30 percent in soil parameters. Both remolded triaxial shear
tests and standard Proctor compaction tests on retaining wall backfill are necessary to obtain more
precise design parameters. This testing was not included in our present scope of work. If
authorized, we will perform laboratory tests to obtain site-specific design soil parameters.

Existing site soils may be used as backfill behind the retaining walls. We recommend that these
materials be compacted to at least 95 percent of their standard Proctor maximum dry density. Either
light, hand-operated compaction equipment must be used within 4 feet of walls to reduce the risk of
over-stressing the walls, or the walls must be designed to resist the stresses imposed by large
compaction equipment.

7.9 Slopes

Generally, permanent cut and fill slopes should be no steeper than 2H:1V and temporary slopes no
steeper than 11⁄2H:1V. These slope recommendations are based on our previous experience
with similar conditions since no detailed slope stability analysis was performed to justify steeper
slopes.

 

 

			
	Biomass Cogeneration Facility
	 	April 18, 2006
	QORE Job No. U1629, Report No. 36127
	 	Page 17

We recommend a building setback of at least 10 feet from the tops of all slopes and a setback of at
least 3 feet for parking area curbs. Drop inlets or storm sewers should not be installed at the
crests of slopes because leakage can result in maintenance problems or possible slope failure.
Crest areas should be sloped to prevent surface runoff from flowing over the slope faces.

It is difficult to construct fill on the specified slopes without leaving a loose, poorly compacted
zone on the slope face. For this reason, we recommend that the fill slopes be slightly over-built,
then cut back to firm, well compacted soils prior to applying a vegetative cover. If the slopes
cannot be slightly over-built and cut back, we recommend that finished soil slopes be compacted to
reduce, as much as practical, the thickness of this soft surficial veneer. The compaction may be
done by making several coverages from top to bottom of the slopes with a track-mounted bulldozer or
front-end loader.

7.10 Pavements

We have calculated flexible pavement section thicknesses for the site based on the laboratory
California Bearing Ratio (CBR) value of 4.4. Prior to paving, we recommend proofrolling the
pavement subgrade in the presence of an engineer from our firm. Some additional undercutting and/or
compaction of the subgrade soils may be required. Based on information provided, we used a design
frequency of 100 semi tractor trailers per day for the heavy duty section. These traffic loading
and frequency distributions were used to develop recommendations for a 20-year design period using
design procedures based on AASHTO guidelines. The design period is considered the time interval
over which the pavement, with proper maintenance, will not require major repairs such as an
overlay. A continuing regular maintenance program should be implemented to maintain a satisfactory
serviceability level over the design period. The maintenance program should include sealing cracks
and repairing minor deficiencies before they become major problems.

The recommended pavement sections are provided in the table below. The heavy duty section should be
used where any trucks may operate. The normal duty section should be used where only automobiles
and occasional light truck traffic may operate.

The pavement section designs presented here are based upon the assumed traffic loading. Some damage
may occur in localized areas during periods of abnormally heavy traffic loads, such as from
repeated passage of construction equipment, heavily loaded delivery, haul or concrete trucks,
during construction.

We recommend a frequency of at least one density test for every 3,000 square feet of base course.
Asphalt placement should be monitored full-time and we recommend a frequency of at least one
density test for every 3,000 square feet of asphaltic concrete pavement. Asphalt samples should be
obtained periodically and tested for asphalt cement content, aggregate gradation, and Marshall
density.

Some damage may occur in localized areas during periods of abnormally heavy traffic loads, such as
from repeated passage of construction equipment (heavily loaded delivery, haul, or concrete
trucks).

We recommend a frequency of at least one density test for every 3,000 square feet of base. We
recommend a frequency of cutting at least one core for every 3,000 square feet of asphaltic
concrete pavement for thickness and apparent density verification.

9.0 FOLLOW-UP SERVICES

Our services should not end with the submission of this geotechnical report. QORE should be kept
involved throughout the design and construction process to maintain continuity and to determine if
our recommendations are properly interpreted and implemented. To achieve this, we should review
project plans and specifications with the designers to see that our recommendations are fully
incorporated and have not been misinterpreted.

QORE’s familiarity with the site and with the foundation recommendations makes us a valuable part
of your construction quality assurance team. QORE recommends that we be retained by the owner to
observe earthwork and foundation construction. Our personnel are uniquely qualified to recognize
unanticipated ground conditions and can offer responsive remedial recommendations should these
unanticipated conditions occur.

QORE appreciates the opportunity to be of service to you in this phase of the project. We are
available to provide consulting services and quality control testing during the construction phase.
Please call us if you have any questions concerning this report or if we may be of further service.

	Fluidized Bed Combustors
	 	Page 1 of 3

Fluidized bed combustion systems use a heated bed of sand-like material suspended (fluidized)
within a rising column of air to burn many types and classes of fuel. This technique results in a
vast improvement in combustion efficiency of high moisture content fuels, and is adaptable to a
variety of “waste type fuels. The scrubbing action of the bed material on the fuel particle
enhances the combustion process by stripping away the carbon dioxide and char layers that normally
form around the fuel particle. This allows oxygen to reach the combustible material much more
readily and increases the rate and efficiency of the combustion process.

Bed Recycle System

The key to EPI’s dominance of the difficult waste fuel combustion market is our patented bed
recycle system. EPI is the only company that offers uniform bed drawdown, integrated air cooling
and automatic cleaning and reinjection of the bed material. This innovative feature enables EPI
systems to operate on fuels with significant quantities of 4-inch minus noncombustible tramp
material (contaminants such as rocks, metal. etc.). In grate style systems, tramp materials and ash
slag can cause significant problems requiring a shutdown to correct. In other fluidized bed
systems, tramp materials can build to the point that fluidization is no longer possible allowing
clinkers to form. In these systems, a shutdown is usually also required to clean out the
accumulation.

Complete and Efficient Combustion.

The turbulence in the combustor vapor space combined with the tumultuous scouring effect and
thermal inertia of the bed material provide for complete, controlled and uniform combustion. These
factors are key to maximizing the thermal efficiency, minimizing char, and controlling emissions.
The high efficiency of a fluid bed combustor makes it particularly well suited to problem fuels
with low BTU value and high moisture characteristics. EPI’s systems have consistently achieved high
combustion efficiencies. In typical units, the carbon burnout percentages within the combustor are
well in excess of 99 percent.

Waste Fuel Diversity

EPI systems have operated on fuels as diverse as agricultural waste, municipal solid waste, wood
wastes, industrial and municipal sludges, plastic, tires and coal. Fluidized bed systems are also
capable of efficiently combusting fuels of varying consistency. EPI units have demonstrated the
ability to handle a variety of wastes within a single combustor. EPI’s San Joaquin Valley Energy
Project units have logged operating time over 68 varieties of agricultural and urban wood waste.
EPI’s patented bed cleaning system, which removes large non-combustible material from the bottom of
the bed, allows EPI units to burn otherwise problematic fuels with a minimal amount of processing.

Low Emissions

Emissions from a fluidized bed unit are inherently lower than conventional technologies for the
following reasons:

		 	Low combustion temperatures and low excess air within the bed reduces the formation of certain
emissions such as NOx.
	 
		 	High combustion efficiency results in flue gases that contain low amounts of CO.
	 
		 	Emissions such as SOx and NOx may be abated within the fluidized bed system by
injecting limestone into the bed and ammonia into the vapor space.

These features of fluidized bed combustion, combined with EPI’s vast experience with a variety of
fuels have allowed EPI units to comply with some of the most stringent air quality regulations in
the country, including six operating plants in California. EPI units have consistently been
accepted as the Best Available Control Technology “BACT” by environmental regulatory agencies.

Favorable Ash Properties

The high combustion efficiency of a fluid bed results in a reduced amount of inorganic material as
fine ash. The remaining larger material consists mainly of non-combustibles, such as rocks, and
wire brought in with the fuel, and coarse sand-like neutral particles. Low combustion temperatures
in the fluidized bed minimize the formation of toxic materials that might go into the ash. Ash
samples from EPI systems have consistently tested nontoxic, and in many instances the ash is being
sold as input for other products such as cement.

Operating Flexibility

EPI’s fluidized bed systems have demonstrated the ability to operate under a wide range of load
conditions. The thermal “flywheel” effect of the bed material allows swings in moisture and heating
content of the fuel to be absorbed by the system without negative impact. Conversely, the low fuel
inventory present in the unit makes it very responsive to varying loads. The fluidized bed also
maintains efficiency during system turn-down. The operating flexibility demonstrated by existing
EPI units has proven quite valuable for some of EPI’s customers allowing them to take advantage of
utility incentive programs for generation that follows electric demand.

Low Operating Costs

The lack of moving parts in a fluid bed reduces maintenance costs and down time. EPI units have
achieved operating availabilities above 98% and have kept operating costs relatively low given the
difficult fuels they are burning.

Environmentally Sound Energy Production from Waste

Fluidized bed combustion is an environmentally favorable, proven technology for disposal of solid
wastes and generation of energy. The combination of EPI’s vast experience in developing solutions
for a wide variety of applications, with the favorable characteristics of

The Hurst HD Hybrid Series combines the benefits of a watertube furnace along with a multi-pass
firetube boiler vessel. The resulting efficiency of the Hybrid design is higher than conventional
packaged boilers. This efficiency is achieved by superior utilization of the fuel’s radiant heat
within the water-cooled furnace as well as the Hybrid’s balanced multi-pass firetube vessel
resulting in low stack temperatures.

The HD Series will efficiently burn any liquid or gaseous fuel and is available from 100 to 2500
horsepower with pressures of 160-PSI hot water or 450-PSI steam.

 

 

Solid Fuel Fired Steam Boilers

Hurst Hybrid Series involves years of engineering and construction of the wood, coal, and solid
waste fired fuel systems.  
The Hybrid design combines the benefits of a watertube furnace along
with a multipass firetube boiler vessel. The resulting efficiency of the Hybrid design is higher
than conventional solid fuel boilers. This efficiency is achieved by superior utilization of the
fuels radiant heat within the water cooled furnace as well as the Hybrid’s balanced multi-pass
firetube vessel resulting in low stack temperatures. The Hybrid is adaptable to dry wood, wet wood,
coal and an array of other waste fuels. Furthermore, the watertube furnace allows for efficient
firing of auxiliary fuels (gas, fuel oil, and waste oil).

FEEDWATER DEAERATORS

WHY DEAERATE?

     The use of deaerators has long been used in power plants and water tube type boilers, primarily
because they remove undissolved oxygen and raise the temperature of the feedwater. These advantages
are important today for firetube boilers as well, due to higher capital investments.

     Operating costs can be reduced by recovering flash steam when returned by high temperature
condensate. This feature also raises the feedwater temperature, thus requiring less boiler fuel to
convert the feedwater to useable steam.

     Boiler tubes, condensate lines, and process piping have a much longer useful life by eliminating
the pitting action of untreated water. This advantage alone justifies the cost of an “OXY-MISER”
deaerator.

PROJECT 10167 Rev 2

March 26, 2008

 

 

1. Turbine general description

The machine is an extraction-condensing multistage steam turbine, model TMCE 25000A manufactured
by TGM Turbines. The machine is provided with a horizontally split casing. The top portion has a
built-in block with independent steam control valves, directly actuated by independent hydraulic
servo-motors, which provides excellent speed stability and part load performance.

There are two emergency trip valves, one installed at upper casing steam block and the other
is supplied loose to be installed in the client’s extraction steam line. Both are hydraulically
actuated.

The rotor consists of 01 control wheel and several stages which designed to meet the stated
performance. Wheels and shaft are made of a single and integral forged steel piece. The shaft
rests on tilting pads type radial and axial bearings.

The rotor assembly includes a balance piston, which compensates the axial forces acting on the
rotor by using the steam exhaust pressure to reduce the axial thrust. Labyrinth seals provide the
sealing.

The turbine is provided with thermal insulation and lagging in steel plates.

A sound enclosure can be provided over the turbine and gear to the reduce noise level below 85
dba.

The turbine and speed reducer is furnished on a common baseplate.

The complete lube oil system including the AC auxiliary oil pump, DC emergency oil pump, dual oil
coolers, dual oil filters, and oil reservoir are provided on a separate skid, The main oil pump is
shaft driven off the low speed side of the gear.

GENERAL INFORMATION:

APPLICABLE STANDARDS:

The machines are designed, manufactured and tested according to standards ABNT, NEMA, IEEE, IEC
and DIN, where applicable. Specifically we can mention:

NBR 5110 — Cooling methods.

NBR 5052 — Synchronous machines.

NBR 5117 — Synchronous machines.

ISO 1940 — Balancing quality.

VDE 0530 — Turning electrical machines.

NEMA MG-1 Part 32 and 33 — Synchronous Generators.

GENERAL CONSTRUCTION:

An alternating-current generator consists essentially of a magnetic circuit, dc field winding, ac
armature winding and mechanical structure, which includes cooling and lubrication. The magnetic
circuit and field windings are arranged in certain way that, as the machine spins, the magnetic
flow linking the armature windings

 

 

changes cyclically, and for this reason induces alternate voltage in armature winding.

There are many possible geometrical arrangements for these elements, and each one with its own
advantages. Usually the salient pole construction is used for low speed rotors such as the ones
used in diesel an hydroelectric power stations, and the cylindrical rotor machine for
steam-turbine driven generators. WEG’s standard for high-speed application is the cylindrical
rotor type because of the lower centrifugal forces created, and also because it
lessens/eliminates some harmonics and high frequency interference with other equipments.

FUNCTIONS:

The mechanical and electrical characteristics as well as the performance of an electric generator
are a consequence of the magnetic circuit design. Because output results from the interaction
between current-carrying armature conductors, the air-gap flux and it is proportional to their
product, when designing the magnetic circuit WEG design provides the correct space for the windings
and the right path for the magnetic flux.

DESIGNING THE MAGNECTIC CIRCUIT:

The right design of the pole pitch and the number of poles assures always the best path for the
circuit. As the number of poles decreases, the restrictions in space available in the rotor
result in most of the magnetic circuit dimensions being a smaller proportion of the pole pitch.
The armature slot width is determined principally by the insulation thickness required for the
machine voltage and is commonly such that the resulting total copper width per slot is 40 to 60%
of the slot width.

MATERALS AND LOSSES:

To reduce Foucault currents caused by variations of the air gap flux density, and also to reduce
losses in the rotor pole faces, WEG selected the cylindrical type rotor instead of the high
stressed salient pole machines. Always when this type of pole is used we notice the air gap is
relatively large and the losses decrease to acceptable values. Most salient-pole machines on the
other hand, have smaller air gaps relative to the armature slot widths.

To improve the good characteristics of the cylindrical-pole configuration, our design also use
laminated poles. We can use one-piece laminations or segmental laminations, depending on the
machine size and the available widths of the electrical sheet of steel. Mostly WEG uses 3.5%
silicon electrical sheet steel in 0.014 to 0.025 in thickness. This sheets are stamped at WEG,
because quality and grain orientation. The correct finishing includes polishing and painting

 

 

of each individual sheet. During testing, when submitted to high flux densities the advantages of
this construction come to view in the general efficiency.

PERFORMANCE:

The field current required for a particular load condition is determined by the magnetic circuit
in conjunction with its armature and field windings. This is calculated during design by
evaluating the flux densities and the corresponding ampere-turns in all parts of the magnetic
circuit. After the machine is built, the magnetic characteristics are shown in the performance
report.

FRAME:

WEG’s electric generator’s frames are built entirely using steel sheets and MIG welded profiles.
It’s well known by its strength and mechanical resistance. It can be manufactured in many different
arrangements, and the most usual ones are B3 (with terminal boxes placed sideways) or D5 whose
characteristics include pedestal bearings and terminal box located at the bottom of the generator,
inside air outlet.

CLASSES OF INSULATION:

To assure long electrical/overall life, the temperature of operation should never surpass the
insulation class temperature of the materials used in the generator construction.

As result, the table below shows standard temperatures for the most common classes used for
this size of generators:

	 	 	 	 	 
	Insulation Class	 	Temperature Class	 	Temperature rise oC
	F
	 	155oC
	 	105oC max (or 80oC)

ARMATURE WINDING INSULATION:

As standard armature voltages can vary from 220 up to 18,000 V, it is necessary to ensure the
appropriate amounts of turn-turn and turn-ground insulation used to withstand different situations,
such as steady state or transients. In low voltage systems the turn-turn insulation may be applied
directly to the conductor as a film. In higher voltages it is necessary special methods to prevent
corona effects.

Despite of this recommendation, WEG assures all equipment here manufactured use the same
treatment, which consists in Vacuum and Pressure Impregnation.

 

 

IMPREGNATION WITH VARNISH:

After winded both stator and rotor are submitted to deep vacuum varnish impregnation (VPI),
which fills completely all existing remaining gaps. We use polyester varnish, and it assures an
insulation class F (or superior) with temperature class of 155oC (337oF).

COOLING SYSTEM:

Heat generated by internal losses must be exhausted to keep the internal temperature stable and
under standard values. Usually heat is transferred directly to air and this air can either be
cooled in a closed circuit by an outside water or air-cooling system (indirectly cooling system) or
can be exhausted (directly cooled system). In the first case, a closed circuit, there is no
possibility of debris formation on the coils, as it may occur in the second case.

WEG manufactures generators for both applications with a protection degree of IP-23 (open) or
IP-54/55/65 (closed).

Stators are frequently cooled by blowing air over the coil ends and through radial channels in the
armature core. The channels are normally in the range of 6 up to 8mm wide, with spacing between
each other of about 50mm, but they may be omitted entirely on machines with short core lengths.

MECHANICAL COMPARISON BETWEEN SALIENT POLE AND PLAIN POLE ROTORS:

The field configuration, salient pole and plain pole rotors distinguish two fundamental variations
in the mechanical construction. In most but the smallest modern alternators and in some ac brush
less exciters, the field is the rotating element, and the armature is the stationary element
(stator). Salient pole construction, where the field windings are on pole pieces attached to a
rotor body, is used on slower speed machines, 1200 rpm and lower, because of it’s relatively lower
cost. Plain pole construction, where the field windings are inserted in axial slots in a
cylindrical rotor body, is used on essentially all 2 poles and on the larger 4 pole machines,
because it minimizes the problems of fitting salient poles to the rotor body, which in such
high-speed machines become non-practical and too risky. The fundamentals of stator core and
winding construction for these two types of design are the same, but as far as the mechanical
behaviour and life expectancy is concerned the plain pole cylindrical rotor is superior.

BEARINGS:

 

 

Smaller AC generators can be furnished with ball anti-friction bearings when the load and speed
are not critical and operate very well as long as a preventative maintenance program is followed.

However, the majority of the AC generators are supplied with oil-lubricated babbitted
bearings. For horizontal shafts these are self-contained ring-oiled bearings when design
conditions permit.

At higher shaft peripheral speeds and higher bearing loadings ring-oiling is supplemented with
forced circulation of external cooled oil. The rings may be replaced by an external source, such as
the same lubricating system used by the turbine, or WEG can supply a self-sustained lubrication
system.

Lead base babbitted bearings are commonly used for journal bearings, although tin-base babbitt may
be employed in heavy-duty applications.

All bearings have an electrical connection to the ground to isolate electrical currents.

SPACE HEATERS:

To avoid water condensing inside generator, this equipment is built with an electrical resistance
that can be powered from any typical 240 VAC outlet. This way it can be stored for a long time,
as long as the heater is on.

BALANCING:

The standard mechanical balancing adopted by WEG is stated by ISO 1940, which defines the possible
grades, N (Normal), R (reduced) or S (special). Our Quality Control does not allow any rotor to
continue in the manufacturing process chain if it reached a degree above R 2,5 (Reduced).

For this reason we can assure a long reliable life, and low bearing wear, as well as no vibration
is transmitted to other related machines.

COATING:

All generators have its internal and external surface treated with steel debris blasting until
it reaches the cleanness degree Sa 2.1/2.

First coating is applied using polyamide epoxy 35 – 40 microns thick.

Finishing consists into two polyamide epoxy coatings, each one 70-80 microns thick, with
standard colour Medium Blue RAL 5007.

 

 

The coating process is designed to allow the machine to be installed in regular-aggressive acid
atmosphere with good resistance to alkaloids and humidity, typical for Sugar — Alcohol
distilleries, Paper, Wood or related industrial processes, etc...

QUALITY INSPECTION:

All Manufactured generators are factory thoroughly tested. There is a standard testing
procedure, and it is completed with no exceptions.

Special tests can be performed with or without witness/inspection, but it should be agreed between
buyer and seller before the PO is placed so it can be scheduled in advance. Any changes after that
may affect final price, delivery time, and the chronology established when the unit is being
manufactured. Such chronology is very important due to the available time in the testing lab, as
all products are tested, and some of them have a specific deadline to be followed.

ELECTRONIC/MICROPROCESSED VOLTAGE REGULATOR:

The main purpose of the voltage regulator is to keep a steady output voltage at any load condition.
It may include functions such as allowing synchronization with other generators and/or power
utilities, allowing power factor correction, and allowing reactive power compensation throughout
the capability curve.

WEG uses an electronic and high-speed micro processed voltage regulator in order to assure such
flexible operation.

Recommended quality for cooling water

The materials selection for steam condenser and heat exchanger is directly related to the type
of cooling water used (aggressiveness). It becomes clear that water aggressiveness in continuous
operation should not increase in relation to the value originally specified, because it may reduce
significantly the average lifetime of the equipment.

Besides, deposits on the tubes decrease the heat exchange efficiency and speed up internal
corrosions.

In order to assure safe operation, some basic requirements have to be followed, as indicated below:

Open circuit cooling

The total amount of salt shall not exceed 100 mg/l. Water shall have adequate chemical composition
because treatments are not applicable.

In case of particles in suspension, filtering must be applied. Seaweed can be eliminated by
clorification. To avoid separation of carbonates, it’s necessary to keep the balance of the
calcium/carbonic acid rate.

Closed circuit cooling

The following figures shall be kept:

 

 

	 	 	 

	PH
	 	7
	Carbonic acid
	 	3 g/l
	Carbonate hardness
	 	6°dH
	Carbonate hardness for polymorph phosphates
	 	12°dH
	Non-carbonate hardness
	 	80°dH
	Clorets
	 	400 mg/l
	Sulfates
	 	500 mg/l
	Total salt
	 	3000 mg/l
	Total alkalinity
	 	15 mgl/l
	Silic acid
	 	200 mg/l
	Particles in suspension
	 	10 mg/l

Note: Water flow shall be periodically inspected. The water chambers must be always clean.

Note: There are a number of codes and standards listed in the matrix with a specific revision
date (e.g. NFPA 70-2005). When a Design Authority or Design
Agency wants to use a later revision (successor) of a code or standard that is listed by a specific
date, they must first perform an engineering evaluation per
WSRC-TM-95-1, Responsibilities and Requirements.
