                           FORM AND TERMS OF THE NOTES

Section 201.   FORM AND DATING.

            (a) GENERAL. The Notes and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit A hereto. The Notes
may have notations, legends or endorsements required by law, stock exchange rule
or usage. Each Note shall be dated the date of its authentication. The Notes
shall be in denominations of $1,000 and integral multiples thereof.

            The terms and provisions contained in the Notes shall constitute,
and are hereby expressly made, a part of this Indenture and the Company, the
Guarantors and the Trustee, by their execution and delivery of this Indenture,
expressly agree to such terms and provisions and to be bound thereby. However,
to the extent any provision of any Note conflicts with the express provisions of
this Indenture, the provisions of this Indenture shall govern and be
controlling.

            (b) GLOBAL NOTES. Notes issued in global form shall be substantially
in the form of Exhibit A attached hereto (including the "Schedule of Exchanges
of Notes" attached thereto). Notes issued in definitive form shall be
substantially in the form of Exhibit A attached hereto (but without the
"Schedule of Exchanges of Notes" attached thereto). Each Global Note shall
represent such of the outstanding Notes as shall be specified therein and each
shall provide that it shall represent the aggregate principal amount of
outstanding Notes from time to time endorsed thereon and that the aggregate
principal amount of outstanding Notes represented thereby may from time to time
be reduced or increased, as appropriate, to reflect exchanges and redemptions.
Any endorsement of a Global Note to reflect the amount of any increase or
decrease in the aggregate principal amount of outstanding Notes represented
thereby shall be made by the Trustee or the Custodian, at the direction of the
Trustee, in accordance with instructions given by the Holder thereof as required
by Section 206 hereof.

Section 202.   EXECUTION AND AUTHENTICATION.

            Two Officers shall sign the Notes for the Company by manual or
facsimile signature. The Company's seal shall be reproduced on the Notes and may
be in facsimile form.

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

            A Note shall not be valid until authenticated by the manual
signature of the Trustee. The signature shall be conclusive evidence that the
Note has been authenticated under this Indenture.

            The Trustee shall, upon a written order of the Company signed by one
Officer (an "AUTHENTICATION ORDER"), authenticate Notes for original issue up to
the aggregate principal amount stated in paragraph 4 of the Notes. The aggregate
principal amount of Notes outstanding at any time may not exceed such amount
except as provided in Section 306 of the Base Indenture.

            The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Notes. An authenticating agent may authenticate Notes
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with Holders or an
Affiliate of the Company.

Section 203.   REGISTRAR, DEPOSITARY AND PAYING AGENT FOR NOTES; PAYING AGENT
               TO HOLD MONEY IN TRUST.

            The Company shall maintain an office or agency where Notes may be
presented for exchange ("REGISTRAR") and an office or agency where Notes may be
presented for payment ("PAYING AGENT"). The Registrar shall keep a register of
the Notes and of their transfer and exchange. The Company may appoint one or
more co-registrars and one or more additional paying agents. The term
"Registrar" includes any co-registrar and the term "Paying Agent" includes any
additional paying agent. The Company may change any Paying Agent or Registrar
without notice to any Holder. The Company shall notify the Trustee in writing of
the name and address of any Agent not a party to this Indenture. If the Company
fails to appoint or maintain another entity as Registrar or Paying Agent, the
Trustee shall act as such. The Company or any of its Subsidiaries may act as
Paying Agent or Registrar.

            The Company initially appoints The Depository Trust Company ("DTC")
to act as Depositary with respect to the Global Notes.

            The Company initially appoints the Trustee to act as the Registrar
and Paying Agent and to act as Custodian with respect to the Global Notes.

            The Company shall require each Paying Agent other than the Trustee
to agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium, if any, or interest on the Notes, and will notify the
Trustee of any default by the Company in making any such payment. While any such
default continues, the Trustee may require a Paying Agent to pay all money held
by it to the Trustee. The Company at any time may require a Paying Agent to pay
all money held by it to the Trustee. Upon payment over to the Trustee, the
Paying Agent (if other than the Company or a Subsidiary) shall have no further
liability for the money. If the Company or a Subsidiary acts as Paying Agent, it
shall segregate and hold in a separate trust fund for the benefit of the Holders
all money held by it as Paying Agent. Upon any bankruptcy or reorganization
proceedings relating to the Company, the Trustee shall serve as Paying Agent for
the Notes.

Section 204.   TRANSFER AND EXCHANGE OF NOTES.

            (a) TRANSFER AND EXCHANGE OF GLOBAL NOTES. The transfer and exchange
of beneficial interests in the Global Notes shall be effected through the
Depositary, in accordance with this Supplemental Indenture and the procedures of
the Depositary therefor, which shall include restrictions on transfer comparable
to those set forth herein to the extent required by the Securities Act.
Beneficial interests in the Global Notes may be transferred to Persons who take
delivery thereof in the form of a beneficial interest in the Global Notes.

            (b)   TRANSFER AND EXCHANGE OF DEFINITIVE NOTES.  When Definitive
Notes are presented by a Holder to the Registrar with a request:

            (i)   to register the transfer of the Definitive Notes; or

            (ii)  to exchange such Definitive Notes for an equal principal
                  amount of Definitive Notes of other authorized denominations,
                  the Registrar shall register the transfer or make the exchange
                  as requested if its requirements for such transactions are
                  met; PROVIDED, HOWEVER, that the Definitive Notes presented or
                  surrendered for register of transfer or exchange shall be duly
                  endorsed or accompanied by a written instruction of transfer
                  in form satisfactory to the Registrar duly executed by such
                  Holder or by his attorney, duly authorized in writing.

                                     -15-
<Page>

            (c) RESTRICTIONS ON TRANSFER AND EXCHANGE OF GLOBAL NOTES.
Notwithstanding any other provision of this Indenture (other than the provisions
set forth in subsection (d) of this Section 204), the Global Notes may not be
transferred as a whole except by the Depositary to a nominee of the Depositary
or by a nominee of the Depositary to the Depositary or another nominee of the
Depositary or by the Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary.

            (d)   AUTHENTICATION OF DEFINITIVE NOTES IN ABSENCE OF
DEPOSITARY.  If at any time:

            (i)   the Depositary for the Notes notifies the Company that the
                  Depositary is unwilling or unable to continue as Depositary
                  for the Global Notes and a successor Depositary for the Global
                  Notes is not appointed by the Company within 90 days after
                  delivery of such notice; or

            (ii)  the Company at its sole discretion, notifies the Trustee in
                  writing that it elects to cause the issuance of Definitive
                  Notes under this Indenture,

then the Company shall execute, and the Trustee shall, upon receipt of an
authentication order in accordance with Section 202 hereof, authenticate and
deliver, Definitive Notes in an aggregate principal amount equal to the
principal amount of the Global Notes in exchange for such Global Notes.

            (e) CANCELLATION AND/OR ADJUSTMENT OF THE GLOBAL NOTES. At such time
            as all beneficial interests in the Global Notes have been exchanged
            for Definitive Notes, redeemed, repurchased or canceled, the Global
            Notes shall be returned to or retained and canceled by the Trustee
            in accordance with Section 309 of the Indenture. At any time prior
            to such cancellation, if any beneficial interest in the Global Notes
            is exchanged for Definitive Notes, redeemed, repurchased or
            canceled, the principal amount of Notes represented by the Global
            Notes shall be reduced accordingly and an endorsement shall be made
            on the Global Notes, by the Trustee or the Custodian, at the
            direction of the Trustee, to reflect such reduction.

            (f)   GENERAL PROVISIONS RELATING TO TRANSFERS AND EXCHANGES.

            (i)   To permit registrations of transfers and exchanges, the
                  Company shall execute and the Trustee shall authenticate
                  Definitive Notes and the Global Notes at the Registrar's
                  request.

            (ii)  No service charge shall be made to a Holder for any
                  registration of transfer or exchange, but the Company may
                  require payment of a sum sufficient to cover any transfer tax
                  or similar governmental charge payable in connection therewith
                  (other than any such transfer taxes or similar governmental
                  charge payable upon exchange or transfer pursuant to Section
                  204 hereto).

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

            (iv)  Prior to due presentment for the registration of a transfer of
                  any Note, the Trustee, any Agent and the Company may deem and
                  treat the Person in whose

                                     -16-
<Page>

                  name any Note is registered as the absolute owner of such Note
                  for the purpose of receiving payment of principal of and
                  interest on such Notes, and neither the Trustee, any Agent
                  nor the Company shall be affected by notice to the contrary.

            (v)   The Trustee shall authenticate Definitive Notes and the Global
                  Notes in accordance with the provisions of Section 202 hereof.

Section 205.   CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

            With respect to the Notes issued under this Supplemental Indenture,

            (b) in the case of an election under Section 406 hereof, the Company
shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable
to the Trustee confirming that the Holders of the outstanding Notes will not

such covenant defeasance had not occurred;

            (c) in the case of an election under Section 405 hereof, the Company
shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable

ending on the 91st day after the date of deposit;

            (e) such defeasance or covenant defeasance shall not result in a
breach or violation of, or constitute a default under, any material agreement or
instrument (other than this Indenture) to which

Subsidiaries (or the payment of which is guaranteed by the Company or any of its
Restricted Subsidiaries), whether such Indebtedness or guarantee now exists, or

Section 207.      ACCELERATION OF MATURITY, RESCISSION AND ANNULMENT.

            With respect to the Notes issued under this Supplemental Indenture,
Section 502 of the Base Indenture is hereby replaced in its entirety as follows:

SECTION 502.      Acceleration.

            If any Event of Default (other than an Event of Default specified in
clause (g) or (h) of Section 501 hereof with respect to the Company, any
Restricted Subsidiary that is a Significant Subsidiary or any group of
Restricted Subsidiaries that, taken as a whole, would constitute a Significant
Subsidiary) occurs and is continuing, the Trustee or the Holders of at least 25%
in principal amount of the then outstanding Notes may declare all the Notes to
be due and payable immediately. Upon any such declaration, the Notes shall
become due and payable immediately. Notwithstanding the foregoing, if an Event
of Default specified in clause (g) or (h) of Section 501 hereof occurs with
respect to the Company, any of its Restricted Subsidiaries that are Significant
Subsidiaries or any group of Restricted Subsidiaries that, taken as a whole,
would constitute a Significant Subsidiary, all outstanding Notes shall be due
and payable immediately without further action or notice. The Holders of a
majority in aggregate principal amount of the then outstanding Notes by written
notice to a Responsible Officer of the Trustee may on behalf of all of the
Holders rescind an acceleration and its consequences if the rescission would not
conflict with any judgment or decree and if all existing Events of Default
(except nonpayment of principal, interest or premium that has become due solely
because of the acceleration) have been cured or waived.

            If an Event of Default occurs on or after March 1, 2005 by reason of
any willful action (or inaction) taken (or not taken) by or on behalf of the
Company with the intention of avoiding payment of the premium that the Company
would have had to pay if the Company then had elected to redeem the Notes
pursuant to Section 1109 hereof, then, upon acceleration of the Notes, an
equivalent premium shall also become and be immediately due and payable, to the
extent permitted by law, anything in this Indenture or in the Notes to the
contrary notwithstanding. If an Event of Default occurs prior to March 1, 2005
by reason of any willful action (or inaction) taken (or not taken) by or on
behalf of the Company with the intention of avoiding the prohibition on
redemption of the Notes prior to such date, then, upon acceleration of the
Notes, an additional premium shall also become and be immediately due and
payable in an amount, for each of the 12-month periods beginning on March 1 of
the years set forth below, as set forth below (expressed as a percentage of the
principal amount of the Notes on the date of payment that would otherwise be due
but for the provisions of this sentence):

Section 208.      CONTROL BY MAJORITY.

            With respect to the Notes issued under this Supplemental Indenture,
Section 512 of the Base Indenture is hereby replaced in its entirety as follows:

SECTION 512.      Control by Majority.

            Holders of a majority in principal amount of the then outstanding

corporation); or (ii) sell, assign, transfer, convey or otherwise dispose of all
or substantially all of its properties or assets, in one or more related
transactions, to another Person; unless: (1) either: (a) the Company is the
surviving corporation; or (b) the Person formed by or surviving any such
consolidation or merger (if other than the Company) or to which such sale,
assignment, transfer, conveyance or other disposition shall have been made is a

such sale, assignment, transfer, conveyance or other disposition shall have been
made assumes all the obligations of the Company under the Notes and this
Indenture pursuant to agreements reasonably satisfactory to the Trustee; (3)
immediately after such transaction no Default or Event of Default exists; and
(4) the Company or the Person formed by or surviving any such consolidation or

same had occurred at the beginning of the applicable four-quarter period, either
(a) be permitted to incur at least $1.00 of additional Indebtedness pursuant to
the Fixed Charge Coverage Ratio test set forth in the first paragraph of Section
1009 hereof; or (b) have a Fixed Charge Coverage Ratio that is the same or

of the Company in accordance with Section 803 hereof, the successor corporation
formed by such consolidation or into or with which the Company is merged or to
which such sale, assignment, transfer, lease, conveyance or other disposition is
made shall succeed to, and be substituted for (so that from and after the date
of such consolidation, merger, sale, lease, conveyance or other disposition, the
provisions of this Indenture referring to the "Company" shall refer instead to
the successor corporation and not to the Company), and may exercise every right
and power of the Company under this Indenture with the same effect as if such
successor Person had been named as the Company herein; PROVIDED, HOWEVER, that
the predecessor Company shall not be relieved from the obligation to pay the
principal of and interest on the Notes except in the case of a sale of all of
the Company's assets that meets the requirements of Section 801 hereof.

prospective investors upon request. The Company shall at all times comply with
TIA Section 314(a). Delivery of such reports, information and documents to the
Trustee is for informational purposes only and the Trustee's receipt of such

necessary for certification of such financial statements, nothing has come to
their attention that would lead them to believe that the Company has violated
any provisions of Article 8 or Article 10 hereof or, if any such violation has

it may lawfully do so) that it shall not at any time insist upon, plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay,
extension or usury law wherever enacted, now or at any time hereafter in force,
that may affect the covenants or the performance of this Indenture; and the
Company and each of the Guarantors (to the extent that it may lawfully do so)

of declaration such payment would have complied with the provisions of this
Indenture; (ii) the redemption, repurchase, retirement, defeasance or other

Payments made in cash) shall be the fair market value on the date of the
Restricted Payment of the asset(s) or securities proposed to be transferred or
issued by the Company or such Restricted Subsidiary, as the case may be,

Existing Indebtedness as in effect on March 6, 2001 and any amendments,
modifications, restatements, renewals, increases, supplements, refundings,
replacements or refinancings thereof, PROVIDED that such amendments,
modifications, restatements, renewals, increases, supplements, refundings,
replacements or refinancings are not materially more restrictive, taken as a

Company, with respect to such dividend and other payment restrictions than those
contained in such Credit Facilities or such Existing Indebtedness, as in effect
on March 6, 2001; (ii) this Supplemental Indenture, the Series B Indenture, the
Guarantees, the Series B Guarantees, the Notes and the Series B Notes; (iii)

effect at the time of such acquisition (except to the extent such Indebtedness
was incurred in connection with or in contemplation of such acquisition), which
encumbrance or restriction is not applicable to any Person, or the properties or
assets of any Person, other than the Person, or the property or assets of the
Person, so acquired, provided that, in the case of Indebtedness, such
Indebtedness was permitted by the terms of this Indenture to be incurred; (v)
customary non-assignment provisions in leases entered into in the ordinary
course of business and consistent with past practices; (vi) purchase money
obligations for property acquired in the ordinary course of business that impose
restrictions on the property so acquired; (vii) any agreement for the sale or
other disposition of a Restricted Subsidiary that restricts distributions by
such Restricted Subsidiary pending its sale or other disposition; (viii)
Permitted Refinancing Indebtedness, provided that the restrictions contained in
the agreements governing such Permitted Refinancing Indebtedness are not

judgment of the Board of Directors of the Company, than those contained in the
agreements governing the Indebtedness being refinanced; (ix) Liens securing
Indebtedness otherwise permitted to be incurred pursuant to the provisions of
Section 1012 hereof that limit the right of the Company or any of its Restricted
Subsidiaries to dispose of the assets subject to such Lien; (x) provisions with

with respect to (collectively, "INCUR") any Indebtedness (including Acquired
Debt) and the Company shall not issue any Disqualified Stock and shall not
permit any of its Restricted Subsidiaries to issue any shares of preferred
stock; PROVIDED, HOWEVER, that the Company may incur Indebtedness (including
Acquired Debt) or issue shares of Disqualified Stock if:

            (i) the Fixed Charge Coverage Ratio for the Company's most recently
ended four full fiscal quarters for which internal financial statements are
available immediately preceding the date on which such additional Indebtedness
is incurred or such Disqualified Stock is issued would have been at

                                       -27-

<Page>

least 2.25 to 1, determined on a pro forma basis (including a pro forma

time, under all Credit Facilities incurred under this clause (i) after giving
effect to such incurrence does not exceed an amount equal to $250.0 million;

improvement of property, plant or equipment used in the business of the Company
or such Subsidiary, in an aggregate principal amount not to exceed $50.0 million
at any time outstanding;

            (v)    the incurrence of Indebtedness solely in respect of bankers'
acceptances, letters of credit, surety or performance bonds (to the extent that

Indebtedness being held by a Person other than the Company or a Restricted
Subsidiary thereof and (ii) any sale or other transfer of any such Indebtedness
to a Person that is not either the Company or a Restricted Subsidiary thereof
shall be deemed, in each case, to constitute an incurrence of such Indebtedness
by the Company or such Restricted Subsidiary, as the case may be, that was not
permitted by this clause (vii);

            (viii) the incurrence by the Company or any of its Restricted

Indebtedness of the Company or a Restricted Subsidiary of the Company that was
permitted to be incurred by another provision of this Section 1009;

                                       -28-

<Page>

            (x)    the incurrence by the Company or any of its Restricted
Subsidiaries of additional Indebtedness in an aggregate principal amount (or
accreted value, as applicable) at any time outstanding, including all Permitted
Refinancing Indebtedness incurred to refund, refinance or replace any
Indebtedness incurred pursuant to this clause (x), not to exceed $100.0 million
outstanding at any time;

            (xi)   the incurrence by the Company's Unrestricted Subsidiaries of
Non-Recourse Debt; PROVIDED, HOWEVER, that if any such Indebtedness ceases to be
Non-Recourse Debt, such event shall be deemed to constitute an incurrence of
Indebtedness by a Restricted Subsidiary of the Company that was not permitted by
this clause (xi); and

            (xii)  the accrual of interest, accretion or amortization of
original issue discount, the payment of interest on any Indebtedness in the
form of additional Indebtedness with the same terms, and the payment of
dividends on Disqualified Stock in the form of additional shares of the same
class of Disqualified Stock; provided, in each such case, that the amount
thereof is included in Fixed Charges of the Company as accrued.

            For purposes of determining compliance with this Section 1009, in
the event that an item of proposed Indebtedness (including Acquired Debt) meets
the criteria of more than one of the categories of Permitted Debt described in
clauses (i) through (xii) above, or is entitled to be incurred pursuant to the
first paragraph of this Section 1009, the Company, in its sole discretion, will
be permitted to classify (or later classify or reclassify), in whole or in part,
such item of Indebtedness in any manner that complies with this Section 1009.

SECTION 1010.     Asset Sales.

            The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless: (i) the Company (or the
Restricted Subsidiary, as the case may be) receives consideration at the time of
such Asset Sale at least equal to the fair market value of the assets or Equity
Interests issued or sold or otherwise disposed of; (ii) if the Net Proceeds
received with respect to any Asset Sale exceed $15.0 million, such fair market
value is determined by the Company's Board of Directors and evidenced by a
resolution of the Board of Directors set forth in an Officers' Certificate
delivered to the Trustee; and (iii) except with respect to a disposition of the
Exploration and Production Assets of Odessa (including by way of the sale of the
capital stock of Odessa) or the assets of the operations conducted by the
Company or its Subsidiaries in Argentina and related assets (including by way of
the sale of the Capital Stock of the Subsidiary or Subsidiaries conducting such
operations), at least 75% of the consideration therefor received by the Company
or such Restricted Subsidiary is in the form of cash. For purposes of this
provision, each of the following shall be deemed to be cash: (a) any liabilities
of the Company or any Restricted Subsidiary (other than liabilities that are by
their terms subordinated to the Notes or any Senior Guarantee) that are assumed
by the transferee of any such assets; (b) any securities, notes or other
obligations received by the Company or any such Restricted Subsidiary from such
transferee that are contemporaneously (subject to ordinary settlement periods)
converted by the Company or such Restricted Subsidiary into cash (to the extent
of the cash received in that conversion); (c) any assets received in exchange
for assets in a "like-kind" exchange or an exchange of assets of the Company or
any Restricted Subsidiary for other assets which are useful in the business of
the Company and the Restricted Subsidiaries (whether such assets are of "like
kind"); and (d) any Designated Noncash Consideration (which shall not at any
time exceed, in the aggregate, $30.0 million outstanding.)

            Within 365 days after the receipt of any Net Proceeds from an Asset
Sale, the Company may apply such Net Proceeds at its option: (1) to reduce
permanently Indebtedness under a Credit Facility and to correspondingly reduce
commitments if such Indebtedness constitutes revolving credit borrowings or to
repay permanently any other Indebtedness (other than Indebtedness that by its
terms is

                                       -29-

<Page>

subordinated to the Notes or any Subsidiary Guarantees); (2) to acquire all
or substantially all of the assets of, or a majority of the Voting Stock of,
another Person engaged in a Permitted Business; (3) to make a capital
expenditure; or (4) to acquire other long-term assets that are used or useful
in a Permitted Business.

            Pending the final application of any such Net Proceeds, the Company
may temporarily reduce revolving credit borrowings or otherwise invest such Net
Proceeds in any manner that is not prohibited by this Indenture.

            Any Net Proceeds from Asset Sales that are not applied or invested
as provided in the second preceding paragraph shall constitute Excess Proceeds.
Within 30 days of each date on which the aggregate amount of Excess Proceeds
exceeds $10.0 million, the Company shall make an Asset Sale Offer to all Holders
of Notes and all holders of other Indebtedness that is PARI PASSU with the Notes
containing provisions similar to those set forth in this Indenture with respect
to offers to purchase or redeem with the proceeds of sales of assets to purchase
the maximum principal amount of Notes and such other PARI PASSU Indebtedness
that may be purchased out of the Excess Proceeds. The offer price in any Asset
Sale Offer shall be equal to 100% of principal amount plus accrued and unpaid
interest to the date of purchase, and shall be payable in cash. If any Excess
Proceeds remain after consummation of an Asset Sale Offer, the Company may use
such Excess Proceeds for any purpose not otherwise prohibited by this Indenture.
If the aggregate principal amount of Notes and such other PARI PASSU
Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess
Proceeds, the Trustee shall select the Notes and such other PARI PASSU
Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset
Sale Offer, the amount of Excess Proceeds shall be reset at zero.

SECTION 1011.     Transactions with Affiliates.

            The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate (each, an "AFFILIATE TRANSACTION"), unless: (i) such Affiliate
Transaction is on terms that are no less favorable to the Company or the
relevant Restricted Subsidiary than those that would have been obtained in a
comparable transaction by the Company or such Restricted Subsidiary with an
unrelated Person; and (ii) the Company delivers to the Trustee: (a) with respect
to any Affiliate Transaction or series of related Affiliate Transactions
involving aggregate consideration in excess of $5.0 million, a resolution of the
Board of Directors set forth in an Officers' Certificate certifying that such
Affiliate Transaction complies with this Section 1011 and that such Affiliate
Transaction has been approved by a majority of the disinterested members of the
Board of Directors; and (b) with respect to any Affiliate Transaction or series
of related Affiliate Transactions involving aggregate consideration in excess of
$10.0 million, an opinion as to the fairness to the Holders of such Affiliate
Transaction from a financial point of view issued by an accounting, appraisal or
investment banking firm of national standing.

            The following items shall not be deemed to be Affiliate Transactions
and, therefore, shall not be subject to the provisions of the prior paragraph:
(i) any employment agreement or arrangements (including loan arrangements and
advances) with officers and employees entered into by the Company or any of its
Restricted Subsidiaries in the ordinary course of business; (ii) transactions
between or among the Company and/or its Restricted Subsidiaries; (iii) payment
of reasonable directors fees and the provision of customary indemnification
arrangements to officers, directors and employees of the Company or its
Restricted Subsidiaries; and (iv) Restricted Payments that are permitted by the
provisions of Section 1007 hereof.

                                       -30-

SECTION 1012.     Liens.

            The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume or suffer to
exist any Lien of any kind securing Indebtedness, Attributable Debt or trade
payables on any asset now owned or hereafter acquired, except (i) Permitted
Liens or (ii) if the Obligations under the Notes (or a Guarantee of the Notes)
and this Indenture are equally and ratably secured (or secured on a senior basis
if such other obligations are subordinated to the Obligations under the Notes or
the Guarantees of the Notes) with the other obligations so secured until such
time as such other obligations are no longer secured by such Lien.

SECTION 1013.     Business Activities.

            The Company shall not, and shall not permit any Restricted
Subsidiary to, engage in any business other than a Permitted Business.

SECTION 1014.     Corporate Existence.

            Subject to Article 8 hereof, the Company shall do or cause to be
done all things necessary to preserve and keep in full force and effect (i) its
corporate existence, and the corporate, partnership or other existence of each
of its Subsidiaries, in accordance with the respective organizational documents
(as the same may be amended from time to time) of the Company or any such
Subsidiary and (ii) the rights (charter and statutory), licenses and franchises
of the Company and its Subsidiaries; PROVIDED, HOWEVER, that the Company shall
not be required to preserve any such right, license or franchise, or the
corporate, partnership or other existence of any of its Subsidiaries, 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 its Subsidiaries,
taken as a whole, and that the loss thereof is not adverse in any material
respect to the Holders of the Notes.

SECTION 1015.     Offer to Repurchase Upon Change of Control.

            (a) Upon the occurrence of a Change of Control, the Company shall
make an offer (a "CHANGE OF CONTROL OFFER") to each Holder to repurchase all or
any part (equal to $1,000 or an integral multiple thereof) of each Holder's
Notes at a purchase price equal to 101% of the aggregate principal amount
thereof plus accrued and unpaid interest thereon, if any, to the date of
purchase the "CHANGE OF CONTROL PAYMENT"). Within 10 business days following any
Change of Control, the Company shall mail a notice to each Holder stating: (1)
that the Change of Control Offer is being made pursuant to this Section 1015 and
that all Notes tendered shall be accepted for payment; (2) the purchase price
and the purchase date, which shall be no later than 30 business days from the
date such notice is mailed (the "CHANGE OF CONTROL PAYMENT DATE"); (3) that any
Note not tendered shall continue to accrue interest; (4) that, unless the
Company defaults in the payment of the Change of Control Payment, all Notes
accepted for payment pursuant to the Change of Control Offer shall cease to
accrue interest after the Change of Control Payment Date; (5) that Holders
electing to have any Notes purchased pursuant to a Change of Control Offer shall
be required to surrender the Notes, with the form entitled "Option of Holder to
Elect Purchase" on the reverse of the Notes completed, to the Paying Agent at
the address specified in the notice prior to the close of business on the third
Business Day preceding the Change of Control Payment Date; (6) that Holders
shall be entitled to withdraw their election if the Paying Agent receives, not
later than the close of business on the second Business Day preceding the Change
of Control Payment Date, a telegram, facsimile transmission or letter setting
forth the name of the Holder, the principal amount of Notes delivered for
purchase, and a statement that such Holder is withdrawing his election to have
the Notes purchased; and (7) that Holders whose Notes are being purchased only
in part shall be issued new Notes equal in principal amount to the unpurchased
portion of the Notes surrendered, which unpurchased

                                       -31-

<Page>

portion must be equal to $1,000 in principal amount or an integral multiple
thereof. The Company shall comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to
the extent such laws and regulations are applicable in connection with the
repurchase of Notes in connection with a Change of Control. To the extent
that the provisions of any securities laws or regulations conflict with the
provisions of this Section 1015, the Company will comply with the applicable
securities laws and regulations and will not be deemed to have breached its
obligations under the provisions of this Section 1015 by virtue of such
conflict.

            (b) On the Change of Control Payment Date, the Company shall, to the
extent lawful: (1) accept for payment all Notes or portions thereof properly
tendered pursuant to the Change of Control Offer; (2) deposit with the Paying
Agent an amount equal to the Change of Control Payment in respect of all Notes
or portions thereof so tendered; and (3) deliver or cause to be delivered to the
Trustee the Notes so accepted together with an Officers' Certificate stating the
aggregate principal amount of Notes or portions thereof being purchased by the
Company. The Paying Agent will promptly mail to each Holder of Notes so tendered
the Change of Control Payment for such Notes, and the Trustee shall promptly
authenticate and mail (or cause to be transferred by book entry) to each Holder
a new Note equal in principal amount to any unpurchased portion of the Notes
surrendered, if any; PROVIDED that each such new Note will be in a principal
amount of $1,000 or an integral multiple thereof. The Company will publicly
announce the results of the Change of Control Offer on or as soon as practicable
after the Change of Control Payment Date.

            (c) Notwithstanding anything to the contrary in this Section 1015,
the Company shall not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in this Section 1015 and all other provisions of this Indenture applicable to a
Change of Control Offer made by the Company and purchases all Notes validly
tendered and not withdrawn under such Change of Control Offer.

SECTION 1016.     Intentionally Omitted.

SECTION 1017.     No Amendment of Subordination Provisions.

            Without the consent of each Holder of Notes so affected, the Company
shall not amend, modify or alter the Subordinated Convertible Note Indenture or
the Senior Subordinated Note Indenture in any way that will (i) increase the
principal of, advance the final maturity date of or shorten the Weighted Average
Life to Maturity of any Subordinated Convertible Notes or Senior Subordinated
Notes or (ii) alter the redemption provisions or the price or terms at which the
Company is required to offer to purchase such Convertible Subordinated Notes or
Senior Subordinated Notes in any manner adverse to such Holder.

SECTION 1018.     Limitation on Sale and Leaseback Transactions.

            The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, enter into any sale and leaseback transaction; PROVIDED that
the Company or any Restricted Subsidiary of the Company that is a Guarantor may
enter into a sale and leaseback transaction if: (1) the Company or that
Guarantor, as applicable, could have (a) incurred Indebtedness in an amount
equal to the Attributable Debt relating to such sale and leaseback transaction
under the Fixed Charge Coverage Ratio test in the first paragraph of Section
1009 hereof and (b) incurred a Lien to secure such Indebtedness pursuant to the
provisions of Section 1012 hereof; provided, however, that clause (a) of this
clause (1) shall be suspended during any period in which the Company and its
Restricted Subsidiaries are not subject to the Suspended Covenants; (2) the
gross cash proceeds of that sale and leaseback transaction are at least equal to
the fair

                                       -32-

<Page>

market value, which (if in excess of $10 million) shall be determined in good
faith by the Board of Directors and set forth in an Officers' Certificate
delivered to the Trustee, of the property that is the subject of such sale
and leaseback transaction; and (3) the transfer of assets in that sale and
leaseback transaction is permitted by, and the Company applies the proceeds
of such transaction in compliance with, Section 1010 hereof.

SECTION 1019.     Designation of Restricted and Unrestricted Subsidiaries.

            The Board of Directors may designate any Restricted Subsidiary to be
an Unrestricted Subsidiary if no Default or Event of Default would occur or be
continuing immediately after such designation and taking into effect the
designation. If a Restricted Subsidiary is designated as an Unrestricted
Subsidiary, all outstanding Investments owned by the Company and its Restricted
Subsidiaries in the Subsidiary so designated shall be deemed to be an Investment
made as of the time of such designation and shall reduce the amount available
for Restricted Payments under the first paragraph of Section 1007 hereof or
Permitted Investments, as applicable. All such outstanding Investments shall be
valued at their fair market value at the time of such designation. That
designation shall only be permitted if such Restricted Payment would be
permitted at that time and if such Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary. The Board of Directors may redesignate
any Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation
would not cause a Default or Event of Default as a result of such designation.

SECTION 1020.           Limitation on Issuances of Guarantees of
                        Indebtedness; Additional Guarantors.

            The Company shall not permit any Restricted Subsidiary, directly or
indirectly, to guarantee or pledge any assets to secure the payment of any
Indebtedness of the Company under any Credit Facility unless such Restricted
Subsidiary contemporaneously executes and delivers a supplemental indenture to
this Indenture providing for a Senior Guarantee by such Restricted Subsidiary.
Notwithstanding the foregoing, any Senior Guarantee by a Subsidiary shall
provide by its terms that it shall be automatically and unconditionally released
and discharged upon any sale of all of the capital stock of a Guarantor
(including a sale by way of merger or consolidation), if immediately after
giving effect to such sale, there is no Default or Event of Default that has
occurred or is continuing, or if the Company designates any Restricted
Subsidiary that is a Guarantor as an Unrestricted Subsidiary in accordance with
the applicable provisions of this Indenture. The form of such Senior Guarantee
is set forth in Section 203 of the Base Indenture.

SECTION 1021.     Payments for Consent.

            The Company shall not, and shall not permit any of its Subsidiaries
to, directly or indirectly, pay or cause to be paid any consideration to or for
the benefit of any Holder of Notes for or as an inducement to any consent,
waiver or amendment of any of the terms or provisions of this Indenture or the
Notes unless such consideration is offered to be paid and is paid to all Holders
of the Notes that consent, waive or agree to amend in the time frame set forth
in the solicitation documents relating to such consent, waiver or amendment.

SECTION 1022.     Exchange Offer.

            The Company shall offer, within 60 days of the date of this
Supplemental Indenture, to all Holders of Series B Notes to exchange their
Series B Notes for Notes issued under this Indenture (the "Exchange Offer"). In
the Exchange Offer, the Company shall allow Holders of Series B Notes to
exchange their principal amount of Series B Notes for a like principal amount of
Notes issued under this

                                       -33-

<Page>

Indenture. The Company shall complete the Exchange Offer (i) within 120 days
of the date of this Supplemental Indenture and (ii) in compliance with
Section 3(a)(9) of the Act.

SECTION 1023.     Suspended Covenants.

            During any period of time that the Notes have an Investment Grade
Rating from either of the Rating Agencies and no Default has occurred and is
continuing under this Indenture, the Company and its Restricted Subsidiaries
will not be subject to the covenants contained in Section 801 (to the extent set
forth in Section 801) and in Sections 1007, 1008, 1009, 1010, 1011, 1013, 1017
and 1018 (to the extent set forth in Section 1018) of this Indenture
(collectively, the "SUSPENDED COVENANTS"); PROVIDED, HOWEVER, such covenants
shall not be suspended if the Investment Grade Rating was obtained directly or
indirectly by the merger, consolidation or other acquisition of the Company with
or by a Person that had an Investment Grade Rating from either of the Rating
Agencies and the Company at such time did not have an Investment Grade Rating
from either of the Rating Agencies; and PROVIDED FURTHER, that the covenants
contained in Sections 1003, 1012, 1015, 1019, 1020 and 1021 of this Supplemental
Indenture will not be so suspended; and PROVIDED FURTHER, that if the Company
and its Restricted Subsidiaries are not subject to the Suspended Covenants for
any period of time as a result of the preceding provisions of this Section 1023
and, subsequently, the Rating Agency or Rating Agencies which had given the
Notes an Investment Grade Rating withdraws its or their ratings or downgrades
the ratings assigned to the Notes below the Investment Grade Ratings so that the
Notes do not have an Investment Grade Rating from either Rating Agency, or a
Default (other than with respect to the Suspended Covenants) occurs and is
continuing, the Company and its Restricted Subsidiaries will thereafter again be
subject to the Suspended Covenants, subject to the terms, conditions and
obligations set forth in this Indenture (each such date of reinstatement being
the "REINSTATEMENT DATE"), including those set forth above in this Section 1023.
Compliance with this Section 1023 with respect to Restricted Payments made after
the Reinstatement Date will be calculated in accordance with the terms of
Section 1007 as though such covenant had been in effect during the entire period
of time from which the Notes are issued.

Section 212.      REDEMPTION OF SECURITIES.

            With respect to the Notes issued under this Supplemental Indenture,
the following Sections 1109, 1110 and 1111 supplement Article 11 of the Base
Indenture:

SECTION 1109.     Optional Redemption.

            (a) Except as set forth in clause (b) of this Section 1109, the
Company shall not have the option to redeem the Notes pursuant to this Section
1109 prior to March 1, 2005. Thereafter, the Company shall have the option to
redeem the Notes, in whole or in part, upon not less than 30 nor more than 60
days' notice, at the redemption prices (expressed as percentages of principal
amount) set forth below plus accrued and unpaid interest thereon, if any, to the
applicable redemption date, if redeemed during the twelve-month period beginning
on March 1 of the years indicated below:

        2007 and thereafter....................................     100.000%

</Table>

            (b)   Notwithstanding the provisions of clause (a) of this
Section 1109, at any time prior to March 1, 2004, the Company may on any one or
more occasions redeem up to 35% of the aggregate principal amount of Notes
totally issued under this Indenture at a redemption price of 108.375% of the
principal amount thereof plus accrued and unpaid interest to the redemption
date, with

                                       -34-

<Page>

the net cash proceeds of one or more Equity Offerings; PROVIDED that at least
65% of the aggregate principal amount of the Notes totally issued remains
outstanding immediately after the occurrence of such redemption (excluding
Notes held by the Company and its Subsidiaries); and that the redemption must
occur within 90 days of the date of the closing of such Equity Offering.

            (c) Any redemption pursuant to this Section 1109 shall be made
pursuant to the provisions of Section 1101 through 1108 hereof.

SECTION 1110.     Mandatory Redemption.

            The Company shall not be required to make mandatory redemption
payments or sinking fund payments with respect to the Notes.

SECTION 1111.     Offer to Purchase by Application of Excess Proceeds.

            In the event that, pursuant to Section 1010 hereof, the Company
shall be required to commence an offer to all Holders to purchase Notes (an
"ASSET SALE OFFER"), it shall follow the procedures specified below.

            The Asset Sale Offer shall remain open for a period of 20 Business
Days following its commencement and no longer, except to the extent that a
longer period is required by applicable law (the "OFFER PERIOD"). No later than
five Business Days after the termination of the Offer Period (the "PURCHASE
DATE"), the Company shall purchase the principal amount of Notes required to be
purchased pursuant to Section 1010 hereof (the "OFFER AMOUNT") or, if less than
the Offer Amount has been tendered, all Notes tendered in response to the Asset
Sale Offer. Payment for any Notes so purchased shall be made in the same manner
as interest payments are made.

            If the Purchase Date is on or after an interest record date and on
or before the related interest payment date, any accrued and unpaid interest
shall be paid to the Person in whose name a Note is registered at the close of
business on such record date, and no additional interest shall be payable to
Holders who tender Notes pursuant to the Asset Sale Offer.

            Upon the commencement of an Asset Sale Offer, the Company shall
send, by first class mail, a notice to the Trustee and each of the Holders, with
a copy to the Trustee. The notice shall contain all instructions and materials
necessary to enable such Holders to tender Notes pursuant to the Asset Sale
Offer. The Asset Sale Offer shall be made to all Holders. The notice, which
shall govern the terms of the Asset Sale Offer, shall state:

            (a) that the Asset Sale Offer is being made pursuant to Section 1010
hereof and this Section 1111 and the length of time the Asset Sale Offer shall
remain open;

            (b)   the Offer Amount, the purchase price and the Purchase Date;

            (c)   that any Note not tendered or accepted for payment shall
continue to accrete or accrue interest;

            (d) that, unless the Company defaults in making such payment, any
Note accepted for payment pursuant to the Asset Sale Offer shall cease to
accrete or accrue interest after the Purchase Date;

                                       -35-

<Page>

            (e) that Holders electing to have a Note purchased pursuant to an
Asset Sale Offer may elect to have Notes purchased in integral multiples of
$1,000 only;

            (f) that Holders electing to have a Note purchased pursuant to any
Asset Sale Offer shall be required to surrender the Note, with the form entitled
"Option of Holder to Elect Purchase" on the reverse of the Note completed, or
transfer by book-entry transfer, to the Company, a depositary, if appointed by
the Company, or a Paying Agent at the address specified in the notice at least
three days before the Purchase Date;

            (g) that Holders shall be entitled to withdraw their election if the
Company, the Depositary or the Paying Agent, as the case may be, receives, not
later than the expiration of the Offer Period, a telegram, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of the Note the Holder delivered for purchase and a statement that such
Holder is withdrawing his election to have such Note purchased;

            (h) that, if the aggregate principal amount of Notes surrendered by
Holders exceeds the Offer Amount, the Company shall select the Notes to be
purchased on a PRO RATA basis (with such adjustments as may be deemed
appropriate by the Company so that only Notes in denominations of $1,000, or
integral multiples thereof, shall be purchased); and

            (i) that Holders whose Notes were purchased only in part shall be
issued new Notes equal in principal amount to the unpurchased portion of the
Notes surrendered (or transferred by book-entry transfer).

            On or before the Purchase Date, the Company shall, to the extent
lawful, accept for payment, on a PRO RATA basis to the extent necessary, the
Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale
Offer, or if less than the Offer Amount has been tendered, all Notes tendered,
and shall deliver to the Trustee an Officers' Certificate stating that such
Notes or portions thereof were accepted for payment by the Company in accordance
with the terms of this Section 1111. The Company, the Depositary or the Paying
Agent, as the case may be, shall promptly (but in any case not later than five

equal to the purchase price of the Notes tendered by such Holder and accepted by
the Company for purchase, and the Company shall promptly issue a new Note, and
the Trustee, upon written request from the Company shall authenticate and mail
or deliver such new Note to such Holder, in a principal amount equal to any
unpurchased portion of the Note surrendered. Any Note not so accepted shall be
promptly mailed or delivered by the Company to the Holder thereof. The Company
shall publicly announce the results of the Asset Sale Offer on the Purchase
Date.

            Other than as specifically provided in this Section 1111, any
purchase pursuant to this Section 1111 shall be made pursuant to the provisions

            With respect to the Notes issued under this Supplemental Indenture,

                                       -36-

<Page>

SECTION 1405.     Guarantors May Consolidate, etc., on Certain Terms.

            Except as otherwise provided in Section 1404, no Guarantor may
consolidate with or merge with or into (whether or not such Guarantor is the
surviving Person) another Person whether or not affiliated with such Guarantor
unless:

            (a) subject to Section 1404 hereof, the Person formed by or
surviving any such consolidation or merger (if other than a Guarantor or the
Company) unconditionally assumes all the obligations of such Guarantor, pursuant
to a supplemental indenture in form and substance reasonably satisfactory to the
Trustee, under the Notes, the Indenture and the Senior Guarantee on the terms
set forth herein or therein and immediately after giving effect to such
transaction, no Default or Event of Default exists; or

            (b)   the Senior Guarantee of such Guarantor is to be released
pursuant to Section 1404.

            In case of any such consolidation, merger, sale or conveyance and
upon the assumption by the successor Person, by supplemental indenture, executed
and delivered to the Trustee and satisfactory in form to the Trustee, of the
Senior Guarantee endorsed upon the Notes and the due and punctual performance of
all of the covenants and conditions of this Indenture to be performed by the
Guarantor, such successor Person shall succeed to and be substituted for the
Guarantor with the same effect as if it had been named herein as a Guarantor.
Such successor Person thereupon may cause to be signed any or all of the Senior
Guarantees to be endorsed upon all of the Notes issuable hereunder which
theretofore shall not have been signed by the Company and delivered to the
Trustee. All the Senior Guarantees so issued shall in all respects have the same
legal rank and benefit under this Indenture as the Senior Guarantees theretofore
and thereafter issued in accordance with the terms of this Indenture as though
all of such Senior Guarantees had been issued at the date of the execution
hereof.

            Except as set forth in Articles 8 and 10 hereof, and notwithstanding
clauses (a) and (b) above, nothing contained in this Indenture or in any of the
Notes shall prevent any consolidation or merger of a Guarantor with or into the
Company or another Guarantor, or shall prevent any sale or conveyance of the
property of a Guarantor as an entirety or substantially as an entirety to the
Company or another Guarantor.

                                    ARTICLE 3

                                  MISCELLANEOUS

Section 301.      EFFECT OF HEADINGS.

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

Section 302.      SUCCESSORS AND ASSIGNS.

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

Section 303.      SEPARABILITY CLAUSE.

            In case any provision in this Supplemental 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 304.      SUPPLEMENTAL INDENTURE AND THE BASE INDENTURE.

            For purposes of any Notes issued under this Supplemental Indenture,
in the event that any provision contained in this Supplemental Indenture
conflicts with any provision contained in the Base Indenture, such provision in
this Supplemental Indenture will be deemed to amend and supplement such
provision in the Base Indenture to the extent such provisions conflict, pursuant
to Section 901(4) of the Base Indenture.

Section 305.      NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND
                  STOCKHOLDERS.

            No past, present or future director, officer, employee, incorporator
or stockholder of the Company or any Guarantor, as such, shall have any
liability for any obligations of the Company or such Guarantor under the Notes,
the Senior Guarantees, this Indenture or for any claim based on, in respect of,
or by reason of, such obligations or their creation. Each Holder by accepting a
Note waives and releases all such liability. The waiver and release are part of
the consideration for issuance of the Notes.

Section 306.      GOVERNING LAW.

            This Supplemental Indenture and the Notes created hereby shall be
governed by and construed in accordance with the laws (other than the choice of
law provisions) of the State of New York.

U.S. BANK NATIONAL ASSOCIATION,
as Trustee

By:
    --------------------------------
    Authorized Signature

<Page>

                                 [Back of Note]
                          8 3/8% Senior Notes due 2008

            Unless and until it is exchanged in whole or in part for Notes in
definitive form, this Note may not be transferred except as a whole by the
Depositary to a nominee of the Depositary or by a nominee of the Depositary to
the Depositary or another nominee of the Depositary or by the Depositary or any
such nominee to a successor Depositary or a nominee of such successor
Depositary. Unless this certificate is presented by an authorized representative
of The Depository Trust Company (55 Water Street, New York, New York) ("DTC"),
to the issuer or its agent for registration of transfer, exchange or payment,
and any certificate issued is registered in the name of Cede & Co. or such other
name as may be requested by an authorized representative of DTC (and any payment
is made to Cede & Co. or such other entity as may be requested by an authorized
representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner
hereof, Cede & Co., has an interest herein.

            Capitalized terms used herein shall have the meanings assigned to
them in the Indenture referred to below unless otherwise indicated.

            1.    INTEREST. Key Energy Services, Inc., a Maryland corporation
(the "COMPANY"), promises to pay interest on the principal amount of this Note
at 8 3/8% per annum from March 1, 2002 until March 1, 2008. The Company shall
pay interest, semi-annually in arrears on March 1 and September 1 of each year,
or if any such day is not a Business Day, on the next succeeding Business Day
(each an "INTEREST PAYMENT DATE"). Interest on the Notes will accrue from the
most recent date to which interest has been paid or, if no interest has been
paid, from the date of issuance; PROVIDED that if there is no existing Default
in the payment of interest, and if this Note is authenticated between a record
date referred to on the face hereof and the next succeeding Interest Payment
Date, interest shall accrue from such next succeeding Interest Payment Date;
PROVIDED, FURTHER, that the first Interest Payment Date shall be September 1,
2002. The Company shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal from time to time on
demand at a rate equal to the per annum rate on the Notes then in effect; it
shall pay interest (including post-petition interest in any proceeding under
any Bankruptcy Law) on overdue installments of interest (without regard to any
applicable grace periods) from time to time on demand at the same rate to the
extent lawful. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

            2.    METHOD OF PAYMENT. The Company shall make payments in respect
of the Notes represented by the Global Notes (including principal and interest)
by wire transfer of immediately available funds to the accounts specified by
the Note Custodian. With respect to Notes issued in definitive form, the
Company shall make all payments of principal and interest by mailing a check to
each such Holder's registered address, PROVIDED that all payments with respect
to Notes having an aggregate principal amount of $100,000 or more, the Holders
of which have given wire transfer instructions to the Company at least ten
business days prior to the applicable payment date, will be required to be made
by wire transfer of immediately available funds to the accounts specified by
the Holders thereof. The Notes represented by the Global Notes are expected to
be eligible to trade in DTC's Same-Day Funds Settlement System, and any
permitted secondary market trading activity in such notes will, therefore, be
required by DTC to be settled in immediately available funds. The Company
expects that secondary trading in the Definitive Notes also will be settled in
immediately available funds.

            3.    PAYING AGENT AND REGISTRAR. Initially, U.S. Bank National
Association, the Trustee under the Indenture, will act as Paying Agent and
Registrar.  The Notes may be presented for registration of transfer and
exchange at the offices of the Registrar.  The Company may change any Paying
Agent or Registrar without notice to any Holder.  The Company or any of its
Subsidiaries may act in any such capacity.

<Page>

            4.    INDENTURE. The Company issued the Notes under an Indenture
dated as of February 27, 2002 (the "BASE INDENTURE") as supplemented by a First
Supplemental Indenture dated as of March 1, 2002 (the "SUPPLEMENTAL INDENTURE"
and, together with the Base Indenture, the "INDENTURE" ) between the Company,
the Guarantors and the Trustee. The terms of the Notes include those stated in
the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code Sections 77aaa-77bbbb). The
Notes are subject to all such terms, and Holders are referred to the Indenture
and such Act for a statement of such terms. The Notes issued under the
Indenture are senior unsecured obligations of the Company limited to $1 billion
in aggregate principal amount.

            5.    OPTIONAL REDEMPTION.

            (a)   Except as set forth in subparagraph (b) of this Paragraph 5,
the Company shall not have the option to redeem the Notes prior to March 1,
2005. Thereafter, the Company shall have the option to redeem the Notes, in
whole or in part, upon not less than 30 nor more than 60 days' notice, at the
redemption prices (expressed as percentages of principal amount) set forth
below plus accrued and unpaid interest thereon to the applicable redemption
date, if redeemed during the twelve-month period beginning on March 1 of the
years indicated below:

        Year                                                    Percentage
        ----                                                    ----------
        2005................................................     104.188%
        2006................................................     102.094%
        2007 and thereafter.................................     100.000%

            (b)   Notwithstanding the provisions of subparagraph (a) of this
Paragraph 5, at any time prior to March 1, 2004, the Company may on any one or
more occasions redeem up to 35% of the aggregate principal amount of Notes
totally issued under this Indenture at a redemption price of 108.375% of the
principal amount thereof; plus accrued and unpaid interest to the redemption
date, with the net cash proceeds of one or more Equity Offerings; PROVIDED that
at least 65% of the aggregate principal amount of the Notes totally issued
remains outstanding immediately after such redemption (excluding Notes held by
the Company and its Subsidiaries); and that the redemption must occur within 45
days of the date of the closing of such Equity Offering.

            6.    MANDATORY REDEMPTION.

            The Company shall not be required to make mandatory redemptions or
sinking fund payments with respect to the Notes.

            7.    REPURCHASE AT OPTION OF HOLDER.

            (a)   If there is a Change of Control, the Company shall be
required to make an offer (a "Change of Control Offer") to repurchase all or
any part (equal to $1,000 or an integral multiple thereof) of each Holder's
Notes at a purchase price equal to 101% of the aggregate principal amount
thereof plus accrued and unpaid interest thereon, if any, to the date of
purchase (the "Change of Control Payment"). Within 10 business days following
any Change of Control, the Company shall mail a notice to each Holder setting
forth the procedures governing the Change of Control Offer as required by the
Indenture.

            (b)   If the Company or a Subsidiary consummates any Asset Sale,
under certain circumstances as provided in the Indenture, the Company shall
commence an offer to all Holders of Notes (as "Asset Sale Offer") pursuant to
Section 1111 of the Indenture to purchase the maximum principal amount of Notes
that may be purchased out of the Excess Proceeds at an offer price in cash in
an amount equal to 100% of the principal amount thereof plus accrued and unpaid
interest thereon, if any, to the date

<Page>

of purchase, in accordance with the procedures set forth in the Indenture. To
the extent that the amount of the Excess Proceeds exceeds the aggregate amount
of Notes tendered pursuant to an Asset Sale Offer, the Company (or such
Subsidiary) may use such excess for general corporate purposes. If the
aggregate principal amount of Notes surrendered by Holders thereof exceeds the
amount of Excess Proceeds, the Trustee shall select the Notes to be purchased
on a PRO RATA basis. Holders of Notes that are the subject of an offer to
purchase will receive an Asset Sale Offer from the Company prior to any related
purchase date and may elect to have such Notes purchased by completing the form
entitled "Option of Holder to Elect Purchase" on the reverse of the Notes.

            8.    NOTICE OF REDEMPTION. Notice of redemption will be mailed at
least 30 days but not more than 60 days before the redemption date to each
Holder whose Notes are to be redeemed at its registered address. Notes in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000, unless all of the Notes held by a Holder are to be
redeemed. On and after the redemption date interest ceases to accrue on Notes
or portions thereof called for redemption.

            9.    DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of Notes may be registered and Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company need not
exchange or register the transfer of any Note or portion of a Note selected for
redemption, except for the unredeemed portion of any Note being redeemed in
part. Also, the Company need not exchange or register the transfer of any Notes
for a period of 15 days before a selection of Notes to be redeemed or during
the period between a record date and the corresponding Interest Payment Date.

            10.   PERSONS DEEMED OWNERS. The registered Holder of a Note may
be treated as its owner for all purposes.

            11.   AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
exceptions, the Indenture and the Notes may be amended or supplemented with the
consent of the Holders of at least a majority in principal amount of the then
outstanding Notes voting as a single class, and any existing default or
compliance with any provision of the Indenture or the Notes may be waived with
the consent of the Holders of a majority in principal amount of the then
outstanding Notes voting as a single class. Without the consent of any Holder
of a Note, the Indenture or the Notes may be amended or supplemented to cure
any ambiguity, defect or inconsistency, to provide for uncertificated Notes in
addition to or in place of certificated Notes, to provide for the assumption of
the Company's or Guarantor's obligations to Holders of the Notes in case of a
merger or consolidation, to make any change that would provide any additional
rights or benefits to the Holders of the Notes or that does not adversely
affect the legal rights under the Indenture of any such Holder, to comply with
the requirements of the SEC in order to effect or maintain the qualification of
the Indenture under the Trust Indenture Act, or to allow any Guarantor to
execute a supplemental indenture to the Indenture and/or a Senior Guarantee
with respect to the Notes.

            12.   DEFAULTS AND REMEDIES. Events of Default include: (i) default
for 30 days in the payment when due of interest on the Notes; (ii) default in
payment when due of principal of or premium, if any, on the Notes (including in
connection with an offer to purchase); (iii) failure by the Company to comply
with Section 801 or Section 1010 of the Indenture and such failure shall have
continued for 15 days, after notice from the Company or any holder of Notes, or
failure by the Company or any of its Subsidiaries to comply with the provisions
of Section 1007 and Section 1009 of the Indenture and such failure shall have
continued for 30 days after notice from the Company or any holder of Notes;
(iv) failure by the Company for 60 days after notice to the Company by the
Trustee or the Holders of at least 25% in aggregate principal amount of the
Notes then outstanding to comply with

<Page>

certain other agreements in the Indenture and the Notes; (v) payment default
under certain other agreements relating to Indebtedness of the Company or
default under certain other agreements relating to the Indenture which default
results in the acceleration of such Indebtedness prior to its express maturity;
(vi) certain final judgments for the payment of money that remain undischarged
for a period of 60 days; (vii) certain events of bankruptcy or insolvency with
respect to the Company or any of its Restricted Subsidiaries that are
Significant Subsidiaries; and (viii) except as permitted by the Indenture, any
Senior Guarantee shall be held in any judicial proceeding to be unenforceable
or invalid or shall cease for any reason to be in full force and effect or any
Guarantor or any Person acting on its behalf shall deny or disaffirm its
obligations under such Guarantor's Senior Guarantee. If any Event of Default
occurs and is continuing, the Trustee or the Holders of at least 25% in
aggregate principal amount of the then outstanding Notes may declare all the
Notes to be due and payable. Notwithstanding the foregoing, in the case of an
Event of Default arising from certain events of bankruptcy or insolvency, all
outstanding Notes will become due and payable without further action or notice.
Holders may not enforce the Indenture or the Notes except as provided in the
Indenture. Subject to certain limitations, Holders of a majority in aggregate
principal amount of the then outstanding Notes may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders of the
Notes notice of any continuing Default or Event of Default (except a Default or
Event of Default relating to the payment of principal or interest) if it
determines that withholding notice is in their interest. The Holders of a
majority in aggregate principal amount of the Notes then outstanding by notice
to the Trustee may on behalf of the Holders of all of the Notes waive any
existing Default or Event of Default and its consequences under the Indenture
except a continuing Default or Event of Default in the payment of interest on,
or the principal of, the Notes. The Company is required to deliver to the
Trustee annually a statement regarding compliance with the Indenture, and the
Company is required upon becoming aware of any Default or Event of Default, to
deliver to the Trustee a statement specifying such Default or Event of Default.

            13.   TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual
or any other capacity, may make loans to, accept deposits from, and perform
services for the Company or its Affiliates, and may otherwise deal with the
Company or its Affiliates, as if it were not the Trustee.

            14.   NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or stockholder, of the Company, as such, shall not have any
liability for any obligations of the Company under the Notes or the Indenture
or for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the
issuance of the Notes.

            15.   AUTHENTICATION. This Note shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating
agent.

            16.   ABBREVIATIONS. Customary abbreviations may be used in the
name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN
ENT (= tenants by the entireties), JT TEN (= joint tenants with right of
survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A
(= Uniform Gifts to Minors Act).

            17.   CUSIP NUMBERS. Pursuant to a recommendation promulgated by
the Committee on Uniform Security Identification Procedures, the Company has
caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP
numbers in notices of redemption as a convenience to Holders. No representation
is made as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

            The Company will furnish to any Holder upon written request and
without charge a copy of the Indenture. Requests may be made to:

Exhibit 10.14    
  

 
 

AMENDMENT NO. 1 TO LEASE    
  

        THIS AMENDMENT NO. 1 TO LEASE ("Amendment") is made as of October 5, 2001 (the "Effective Date"), between
WJT, LLC, a California limited liability company ("Landlord"), and POLYCOM, INC., a Delaware corporation. 

        THE PARTIES ENTER INTO THIS AMENDMENT based upon the following facts, understandings and intentions: 

        Landlord
and Tenant are now parties to that certain Office Lease executed by Tenant on February 19, 2001 (the "Lease") for the use of approximately fifty thousand three hundred
seventy-five (50,375) net rentable square feet of space in Landlord's building located at 4750 Willow Road in Pleasanton, California. A full and complete copy of the Lease is attached hereto as  Exhibit A.

        A.    The
parties hereto desire to modify the Lease as hereinafter provided. Capitalized terms used herein shall have the same meaning given them in the Lease unless defined
herein. 

        NOW, THEREFORE, IN CONSIDERATION of the mutual covenants and promises of the parties, the parties hereto agree as follows: 

        1.    Term Commencement Date.    

        a.    Definition in Basic Lease Information.    The definitions of the "Term Commencement Date" described in the Basic
Lease Information for the Lease is hereby deleted in its entirety. Instead, the Term
Commencement Date shall be May 15, 2002, regardless of whether the Tenant Improvements are Substantially Complete on May 15, 2002; provided that in no event shall the Term Commencement
Date occur unless and until the Base Building (as defined below) has been completed in accordance with the Base Building Plans. 

        b.    Possession and Lease Commencement.    Section 2 of the Lease is hereby deleted in its entirety and
replaced with the following: 

        2.    Construction of Improvements. The Premises shall be constructed substantially in accordance with plans and specifications
(the "Plans and Specifications") and the Work Letter attached hereto as Exhibit B and made a part hereof. Tenant shall prepare said Plans and
Specifications which shall be approved by Landlord and Tenant prior to commencement of construction in accordance with the Work Letter. The term commencement date ("Term Commencement Date") shall be
May 15, 2002. If, for any reason, Landlord cannot deliver possession of the Premises to Tenant on the Term Commencement Date, Landlord shall not be subject to any liability therefor, Landlord
be in default hereunder, and the obligation of Tenant to pay the Rent due under the Lease shall nonetheless commence on the Term Commencement Date. Notwithstanding the foregoing, if the Premises are
not Substantially Complete by February 1, 2003, then Tenant, as Tenant's sole and exclusive remedy, may terminate this Lease upon written notice thereof to Landlord received prior to
February 28, 2003 (or any earlier date on which the Premises are Substantially Complete). If Tenant shall have failed to deliver such termination notice prior to February 28, 2003, then
Tenant shall be deemed to have waived Tenant's right to terminate this Lease pursuant to this Section 2. If Tenant shall properly terminate this Lease pursuant to this Section 2, then
the Security Deposit prepaid to Landlord shall be promptly returned to Tenant, but the Base Rent paid by Tenant to Landlord from the Term Commencement Date until the date on 

1

 

which such termination becomes effective shall nonetheless remain the property of Landlord. Tenant further acknowledges that no representations as to the condition or repair of the Premises nor
promises to alter, remodel or improve the Premises have been made by Landlord unless such are expressly set forth in this Lease. 

        c.    Term.    Section 3.A. of the Lease is hereby deleted in its entirety and replaced with the following: 

        3.    Commencement Date. The Term of this Lease shall commence on the Term Commencement Date and continue in full force and
effect for One Hundred Twenty (120) months thereafter or until this Lease is terminated as otherwise provided herein. The Base Rent shall be subject to yearly increases pursuant to Paragraph
6.C. hereof. If the Term Commencement Date is a date other than the first day of the calendar month, the Term shall be the number of months of the Term in addition to the remainder of the calendar
month following the Term Commencement Date. Notwithstanding anything to the contrary in this Lease, Landlord warrants and represents that, as of the Term Commencement Date, to the best of Landlord's
knowledge, the Building Shell (as defined in the Work Letter) will comply with all applicable provisions of the law commonly known as Title III of the Americans With Disabilities Act, as promulgated
as of the Term Commencement Date. Landlord shall, promptly after receipt of notice from Tenant, remedy any non-compliance with such warranty at Landlord's sole cost and expense. 

        2.    Basic Operating Cost.    Delete the introductory paragraph to Section 7 of the
Lease in its entirety and replace with the following: 

        (7)    In
addition to the Base Rent required to be paid hereunder, Tenant shall pay, as Additional Rent, Tenant's Proportionate Share of the Basic Operating Building Costs
during any Expense Year, or fraction thereof falling during the term of the Lease, in the Manner set forth below (such amount hereinafter referred to as "Tenant's Proportionate Share of Basic
Operating Building Cost"). 

        3.    Definition of Base Building.    Notwithstanding anything to the contrary in Section 1 of
the Tenant Work Letter attached to the Lease as Exhibit B, the Base Building to be delivered by Landlord to Tenant shall be as described in the
base building plans designated as Plan Check Bulletin No. 4 dated June 15, 2001, including 5 Civil Revisions, as prepared by Hoover Associates (Project Number 1863.00) (the "Base Building
Plans"). Except for (a) the Base Building (including an amount not to exceed $300,000 for changes required by Tenant as set forth in the Base Building Plans, with such amount to be paid from
Tenant's Improvement Allowance), (b) funding of the Tenant Improvement Allowance, (c) schedule extension charges in the amount of $46,000 assessed against Landlord by its contractor as of the
date of this Amendment and (d) any other expense for which Landlord is responsible under the Lease, Landlord shall not be required to incur any other expense in connection with the construction
of the Base Building), Premises or the Tenant Improvements therein. 

        4.    Time Deadlines.    The Time Deadlines for approval of the items described in the Tenant
Work Letter are as described in Schedule 1 attached hereto. 

        5.    Construction Drawings.    The first sentence of Section 3.C. of the Work Letter is
hereby deleted in its entirety and replaced with the following: 

"Upon
the approval of the Final Space Plan by Landlord, but in no event later than November 1, 2001, Tenant shall promptly cause the Architect and 

2

 

the Engineers to complete the architectural and engineering drawings for the Premises, and Architect shall compile a fully coordinated set of architectural, structural, mechanical, electrical and
plumbing working drawings in a form which is complete to allow subcontractors to bid on the work and to obtain all applicable permits (collectively, the "Final Working Drawings") and shall submit the
same to Landlord for Landlord's approval." 

        6.    Construction of Tenant Improvements.    Section 4.A. of the Work Letter is hereby
deleted in its entirety and replaced with the following: 

"A.    Contractor;
Cost Proposal. Landlord and Tenant agree that Devcon Construction Company (the "Contractor") shall build the Tenant Improvements. As part of the construction process,
Tenant has
approved the cost proposal associated with the proposal (the "Cost Proposal") submitted by Contractor and attached hereto as Schedule 2. Upon execution
of this Amendment, Landlord shall be released by Tenant to independently retain Contractor to commence construction of the Tenant Improvements in accordance with the Approved Working Drawings and the
Cost Proposal. 

        7.    Tenant Delays.    Section 5.D.8 of the Work Letter is hereby deleted in its entirety and
replaced with the following: 

        (8)    Any
other acts or omissions of Tenant, or its agents, or employees of which Tenant is given written notice and does not cure within three (3) business days of
receipt of such notice (in the case of the first such notice, and within one (1) business day of receipt of such notice in the case of all subsequent notices) then, notwithstanding anything to
the contrary set forth in the Lease or this Tenant Work Letter and regardless of the actual date of the Substantial Completion of the Tenant Improvements, the Term Commencement Date shall be deemed to
be May 15, 2002. In addition, Tenant shall be responsible for any additional expenses reasonably incurred by Landlord in the building of the Base Building as a direct result of such a Tenant
Delay. 

        8.    Full Force and Effect.    Landlord and Tenant agree that, except as expressly provided
for herein, the Lease shall remain in full force and effect.

PROJECT APPROACH FOR POLYCOM    
  

	1.	 	The following is our approach to managing the Polycom project.
	

 	
 	
DESIGN PHASE:
	

 	
 	

A.	
 	
Design Meetings:
	

 	
 	

 	
 	

Devcon will participate in weekly, or as needed, design/review meetings with the "team" of Polycom and Hoover Associates. Our experience and input will be a valuable asset in guiding the design from conceptual through the working drawings
stage.
	

 	
 	

B.	
 	
On-Site and Off-Site Evaluation:
	

 	
 	

 	
 	

Devcon will provide an evaluation of the existing on-site and off-site utilities and the proposed project layout. Our experience as a developer will also provide additional perspective to this evaluation.
	

 	
 	

C.	
 	
Budget Estimate:
	

 	
 	

 	
 	

Devcon will provide at least four (4) detailed budget estimates for this project. We have included the first budget within Section IX of this proposal. The second budget will be at the 25% drawing stage, the third will be at 40% and the fourth
will be at 80% drawing stage. Our estimates will include not only construction items, but will also include Planning Department fees, Plan Check fees and Building Permit fees required by the City. Devcon will secure these permits.
	

 	
 	

 	
 	

Devcon takes pride in our ability to provide accurate preliminary estimates and to keep track of our estimate through project completion, utilizing our estimating software.
	

 	
 	

D.	
 	
Cost Avoidance:
	

 	
 	

 	
 	

During the Design Phase and at each of the four budget stages, Devcon will propose cost avoidance ideas from both our in-house services and various subcontractors. These cost avoidance ideas will be reviewed with the team to determine their dollar
and/or time benefit to the project. Any and all cost savings on this project will be reflected 100% on the final contract.
	

 	
 	

E.	
 	
Material Selection, Details and Construction Systems:
	

 	
 	

 	
 	

In conjunction with our value engineering efforts, Devcon will assist the project team by providing cost or schedule impact analysis to aid in the selection of materials. We will also help with developing details and construction systems that are
project efficient.
	

 	
 	

F.	
 	
Schedule:
	

 	
 	

 	
 	

Devcon has developed a design/construction schedule. This schedule was developed utilizing the Microsoft Project computerized scheduling system. As necessary during the design and estimating process, Devcon will review and update the
design/construction schedule. (Refer to Section VI—Preliminary Construction Schedule.)
	

 	
 	

 	
 	

We can also develop a cash flow forecast which we can relate to our construction schedule once we have established a guaranteed maximum price.
	

 	
 	

 	
 	

During the schedule review, Devcon will identify and price out any items presenting lead time constraints for pre-construction release.
	
 	
 	

 	
 	

 	
 	

 	
 	

 

 

	

 	
 	
PURCHASING PHASE:
	

 	
 	

A.	
 	
Selection of Mechanical/Electrical/Plumbing & Fire Protection Subcontractors:
	

 	
 	

 	
 	

The timely selection of mechanical, electrical, plumbing and fire sprinkler subcontractors is critical in order to provide appropriate design input to control costs and schedules. From plans and specifications, each of the subcontractors will be
requested to prepare a competitive written proposal for his scope of work. After receiving the request for proposal from at least two (2) subcontractors, each subcontractor will give an oral presentation of his proposal at an interview to be held
jointly with the team. After the interviewing process has been completed, Devcon will make recommendations as to which subcontractors should be selected for this project.
	

 	
 	

B.	
 	
Pre-Purchase of Long-Lead Items:
	

 	
 	

 	
 	

Devcon will work with your design consultant to identify and specify long-lead items. If appropriate, Devcon will solicit bids from the long-lead equipment suppliers and with the purchasing department to pre-order the equipment. We will then assign
it to the low bid subcontractor.
	

 	
 	

C.	
 	
Final Estimate and Bidding:
	

 	
 	

 	
 	

1.	
 	

Upon completion of the drawings issued for bid, Devcon will jointly develop a subcontractor bid list with the team for all trades and prepare instructions to bidders for each bid package (Refer to Section III—Sample Instructions to
Bidders). We will then distribute drawings and competitively bid these items. Where appropriate, Devcon will give consideration to minority owned and small business subcontractors.
	

 	
 	

 	
 	

2.	
 	

Devcon will present sealed bids for opening jointly with the team. After opening the bids, Devcon will conduct a thorough bid analysis and make recommendations as to which subcontractors should be used for the project.
	

 	
 	

 	
 	

3.	
 	

In our bid analysis, Devcon utilizes a matrix format to evaluate bids. Most important is to verify bid scope to ensure an "apples to apples" comparison. As part of our bid evaluation, we meet with bidders to clarify scope of work and confirm their
ability to meet schedule. (Refer to Section III—Bid Analysis Form.).
	

 	
 	

 	
 	

4.	
 	

In today's market, with many subcontractors having heavy workloads and financial problems, it is especially important to pre-qualify subcontractors. Listed below are some of the criteria we use to pre-qualify and select subcontractors:
	

 	
 	

 	
 	

 	
 	
Pre-Qualification
	 	 	 	 	 	 	1.	 	Check financial standing through bank and credit references.
	 	 	 	 	 	 	2.	 	Past experience and performance.
	 	 	 	 	 	 	3.	 	Check work and trade references for similar project experience.
	

 	
 	

 	
 	

 	
 	
Selection
	 	 	 	 	 	 	1.	 	Price and scope of work.
	 	 	 	 	 	 	2.	 	Ability to meet schedule.
	 	 	 	 	 	 	3.	 	Past performance.
	 	 	 	 	 	 	4.	 	Working relationship.
	 	 	 	 	 	 	5.	 	Attitude toward change orders.
	
 	
 	

 	
 	

 	
 	

 	
 	

 

Page 2

 

	

 	
 	

D.	
 	
Purchasing Procedures:
	

 	
 	

 	
 	

Prior to any award, Devcon will meet with each subcontractor to confirm scope of work and schedule. Each award includes a strong commitment by the subcontractor to meet critical milestones on the schedule.
	

 	
 	

 	
 	

Devcon will provide alternative bids for major cost items for Polycom's review and approval. Additionally, we will establish a unit price list for tenant improvement items and potential change orders and will publish the list prior to commencement of
construction.
	

 	
 	

E.	
 	
Contract:
	

 	
 	

 	
 	

Once the subcontractors are selected and the subcontracts are negotiated, Devcon will enter into a standard A.I.A. contract document. This contract will reflect all credits for all acceptable value engineering ideas.
	

 	
 	
CONSTRUCTION PHASE:
	

 	
 	

A.	
 	
Construction Meetings:
	

 	
 	

 	
 	

Devcon's Project Manager will conduct weekly on-site construction meetings with the team. To keep communications flowing between all team members, Devcon will, if requested, assume responsibility for preparing and distributing meeting minutes. (Refer
to Section III—Meeting Minutes.)
	

 	
 	

B.	
 	
Construction Staffing:
	

 	
 	

 	
 	

Devcon will provide full time supervision for all work performed by the general contractor and subcontractors. The Superintendent will hold weekly subcontractor meetings to ensure there is good communication among the trades and a common
understanding of the project's priorities and quality level.
	

 	
 	

 	
 	

The Superintendent records daily project activities using the Project Daily Log. This report is not only a valuable communication tool but it also serves as a permanent project record.
	

 	
 	

C.	
 	
Detailed Construction Scheduling:
	

 	
 	

 	
 	

Devcon utilizes Microsoft Project for scheduling. We have submited a preliminary schedule for your review, which shows the capabilities of our scheduling system. This schedule can be refined as more details are established.
	

 	
 	

 	
 	

Before starting actual construction, Devcon will meet with each subcontractor to confirm crew sizes and activity duration's. This information will be used to update the master schedule.
	

 	
 	

D.	
 	
Short Interval Schedule:
	

 	
 	

 	
 	

Each week, Devcon's Superintendent will prepare a short interval schedule using Microsoft Project, which is detailed by weekly intervals and is used to monitor and update the master Microsoft Project schedule. This short interval schedule is reviewed
in the Superintendent's weekly Subcontractor meeting. It is used as a tool by the Superintendent to commit subcontractors to complete their work on schedule. The short interval schedule is also reviewed in the weekly project meetings and related to
the master schedule. (Refer to Section III—Microsoft Short Interval Schedule.)
	
 	
 	

 	
 	

 	
 	

 	
 	

 

Page 3

 

	

 	
 	

E.	
 	
Submittal Schedule:
	

 	
 	

 	
 	

Devcon also prepares a separate schedule for tracking submittals that is tied into the master schedule. This schedule will be reviewed with Hoover Associates to coordinate with their manpower allocations during the construction phase of the project.
This schedule is also reviewed and updated on a weekly basis. Devcon utilizes a submittal log and submittal form to track submittals through the approval process. (Refer to Section III—Submittal Log and Submittal Form.)
	

 	
 	

F.	
 	
Insurance & Safety:
	

 	
 	

 	
 	

Prior to starting work in the field, Subcontractors must submit Insurance Certificates to Devcon certifying proper coverage.
	

 	
 	

 	
 	

Devcon's Safety Officer will visit the jobsite a minimum of twice weekly to ensure that the site is clean and safe and complies with all applicable OSHA requirements. In addition to these visits, the Superintendent conducts weekly tailgate safety
meetings with all field personnel. Devcon also conducts monthly safety meetings for all supervisory personnel.
	

 	
 	

G.	
 	
Problem Solving Techniques:
	

 	
 	

 	
 	

Devcon's basic philosophy on solving problems is to concentrate on the solution; not the problem. Utilizing all resources at our disposal, we will identify all possible solutions and evaluate any costs or schedule impacts. We make every effort to
mitigate and resolve problems as soon as they occur. Our project managers and superintendents are taught not just to identify the problem but to be prepared to present solutions to problems.

Progress Payments:
	

 	
 	

 	
 	

If requested, monthly progress payment requests will be submitted to WJT, LLC on A.I.A. Form G-702. Each request will include backup documentation as required.
	

 	
 	

I.	
 	
Change Orders:
	

 	
 	

 	
 	

Devcon will provide a detailed estimate showing quantities and unit prices against these quantities. Devcon maintains a fiduciary relationship with Owner and will, therefore, review all subcontractor change order requests and compare them to the unit
price list to ensure the request is fair and accurately priced prior to presentation for Owner approval.
	

 	
 	

 	
 	

All Change Order Requests, including those initiated by the Owner and General Contractor will be made on Devcon's Change Proposal Request Form. Approved Change Proposal Requests can be converted into an A.I.A. Change Order on a monthly basis. Field
change order requests will be handled utilizing our Field work Order Request Form and no work will proceed until authorized signatures have been obtained.
	

 	
 	

J.	
 	
Government Inspections:
	

 	
 	

 	
 	

Devcon's Project Superintendent will coordinate all government inspections. This includes scheduling inspectors and responding to any concerns or discrepancies noted by the inspector.
	

 	
 	

K.	
 	
Punch List:
	

 	
 	

 	
 	

Devcon's philosophy is to have a "Zero Punchlist" project. We ask all of our subcontractors and employees to make this commitment at the beginning of the project. Prior to conducting a punchlist with the Owner and Architect, Devcon prepares its own
punchlist and will complete any deficiencies prior to the Owner/Architect Punchlist. We maintain tight quality control throughout the project and take immediate steps to correct any deficiencies. We demand excellence.

Cost Control/Risk Management:
	

 	
 	

 	
 	

Devcon has an excellent reputation for controlling costs and completing projects within budget. Devcon's Project Manager reviews a detailed cost report which tracks labor man hours, materials and equipment costs against the budget on a weekly basis.
A comprehensive Job Cost Report summary is prepared on a monthly basis. This form summarizes the current contract amount, change orders/adjustments to date and a forecast of projected costs to
complete.
	

 	
 	

 	
 	

By providing timely feedback, our cost reporting system enables us to prevent major cost overruns by taking immediate steps in the field to correct a potential cost overrun situation.
	

 	
 	

M.	
 	
Quality Control:
	

 	
 	

 	
 	

At Devcon, quality control begins with our initial meeting with the subcontractor team. Since every project is made up of different team members, it is important that they understand quality of work required, schedule and scope of work before they
move onto the project. Devcon's Project Manager and Superintendent interview each subcontractor before entering into a contract with him to insure they understand the importance of their part in the project. We also listen to subcontractors for
better ways to integrate building systems and to insure that the architectural details are the most efficient for the project. We communicate our expectations, as well as those of the Owner and Architect, up front, and expect our subcontractors to
meet or exceed those expectations.
	

 	
 	

 	
 	

Once the subcontractor moves onto the site, Devcon's Project Superintendent has primary responsibility for quality control. He conducts a thorough job walk at least twice each day and immediately notifies subcontractors of any concerns or
deficiencies. The Superintendent also conducts a weekly meeting with subcontractors where he reiterates any quality concerns.
	

 	
 	

N.
