whom Options are to be granted; provided, however, that no Option may be granted

The number of Shares issuable to any one Option Holder under
the Plan, together with all of the Company’s other previously established or
proposed share compensation arrangements, shall not exceed 5% of the total
number of issued and outstanding common shares in the capital of the Company on
a non-diluted basis. The number of Shares which may be issued to Insiders under

entitlement granted prior to the Option Holder becoming an Insider may be
excluded in determining the number of Shares issuable to Insiders. 

3.4 Notification of Grant 

Following the granting of an Option, the Administrator shall,
within a reasonable period of time, notify the Option Holder in writing of the
grant and shall enclose with such notice the Option Certificate representing the

necessary Regulatory Approvals for the grant of the Option.

of the Plan. Upon request from any Option Holder, a copy of any amendment

Option Holder.

with the Company to be bound by the terms and conditions of this Plan. In the
event that the Option Holder receives his, her or its Options pursuant to an
oral or written agreement with the Company or a Subsidiary, whether such
agreement is an employment agreement, consulting agreement or any other kind of
agreement of any kind whatsoever, the Option Holder acknowledges that in the
event of any inconsistency between the terms relating to the grant of such
Options in that agreement and the terms attaching to the Options as provided for
in this Plan, the terms provided for in this Plan shall prevail and the other
agreement shall be deemed to have been amended accordingly. 

3.9 Notice 

Any notice, delivery or other correspondence of any kind
whatsoever to be provided by the Company to an Option Holder will be deemed to
have been provided if provided to the last home address, fax number or email
address of the Option Holder in the records of the Company and the Company shall
be under no obligation to confirm receipt or delivery.

authorization to be effective as of the Grant Date of such Options. 

4.2 Number of Shares 

Subject to adjustment as provided for herein, the number of
Shares which will be available for purchase pursuant to Options granted pursuant
to this Plan will not exceed 17,000,000 Shares, less any Shares issued upon the

Stock Option Plan or its 2005 Stock Option Plan. 

- 10 - 

4.3 Fractional Shares 

No fractional shares shall be issued upon the exercise of any
Option and, if as a result of any adjustment, an Option Holder would become
entitled to a fractional share, such Option Holder shall have the right to
purchase only the next lowest whole number of Shares and no payment or other
adjustment will be made for the fractional interest. 

SECTION 5
TERMS AND CONDITIONS OF OPTIONS 

5.1 Exercise Period of Option 

Except as otherwise provided in this Plan, the Grant Date and
the Expiry Date of an Option shall be the dates fixed by the Committee at the
time the Option is granted and shall be set out in the Option Certificate issued
in respect of such Option. 

5.2 Number of Shares Under Option

The number of Shares which may be purchased pursuant to an
Option shall be determined by the Committee and shall be set out in the Option
Certificate issued in respect of the Option. 

5.3 Exercise Price of Option 

The Exercise Price at which an Option Holder may purchase a
Share upon the exercise of an Option shall be determined by the Committee and
shall be set out in the Option Certificate issued in respect of the Option. The
Exercise Price shall not be less than the Market Value of the Shares as of the
Grant Date. The Market Value of the Shares for a particular Grant Date shall be
determined as follows: 

	(a) 	
      for each organized trading facility on which the Shares
      are listed, Market Value will be the closing price of the Shares on such
      organized trading facility on the trading day immediately preceding the
      Grant Date;

	 	 
	(b) 	
      if the Company’s Shares are listed on more than one
      organized trading facility, the Market Value shall be the Market Value as
      determined in accordance with subparagraph (a) above for the primary
      organized trading facility on which the Shares are listed, as determined
      by the Committee, subject to any adjustments as may be required to secure
      all necessary Regulatory Approvals;

	 	 
	(c) 	
      if the Company’s Shares are listed on one or more
      organized trading facilities but have not traded during the ten trading
      days immediately preceding the Grant Date, then the Market Value will be,
      subject to any adjustments as may be required to secure all necessary
      Regulatory Approvals, such value as is determined by the Committee;
    and

	 	 
	(d) 	
      if the Company’s Shares are not listed on any organized
      trading facility, then the Market Value will be, subject to any
      adjustments as may be required to secure all necessary Regulatory
      Approvals, such value as is determined by the Committee to be the fair
      value of the Shares, taking into consideration all factors that the
      Committee deems appropriate, including, without limitation, recent sale
      and offer prices of the Shares in private transactions negotiated at arms’
      length.

Notwithstanding anything else contained herein, in no case will
the Market Value be less than the minimum prescribed by each of the organized
trading facilities that would apply to the Company on the Grant Date in
question.

5.4 Termination of Option 

Subject to such other terms or conditions that may be attached
to Options granted hereunder, an Option Holder may exercise an Option in whole
or in part at any time and from time to time during the Exercise Period. Any
Option or part thereof not exercised within the Exercise Period shall terminate
and become null, void and of no effect as of the Expiry Time on the Expiry Date.
Subject to Section 7.1, the Expiry Date of an Option shall be the earlier of the
date so fixed by the Committee at the time the Option is granted as set out in
the Option Certificate and the date established, if applicable, in paragraphs
(a) or (b) below or sections 6.2, 6.3, 6.4, or 11.4 of this Plan: 

	(a) 	
      Ceasing to Hold Office - In the event that
      the Option Holder holds his or her Option as an Executive and such Option
      Holder ceases to hold such position other than by reason of death or
      Disability, the Expiry Date of the Option shall be, unless otherwise
      expressly provided for in the Option Certificate, the 90th day following
      the date the Option Holder ceases to hold such position unless the Option
      Holder ceases to hold such position as a result
of:

	 	(i) 	
      ceasing to meet the qualifications set forth in the
      corporate legislation applicable to the Company;

	 	 	 
	 	(ii) 	
      a special resolution having been passed by the
      shareholders of the Company removing the Option Holder as a director of
      the Company or any Subsidiary; or

	 	 	 
	 	(iii) 	
      an order made by any Regulatory Authority having
      jurisdiction to so order;

in which case the Expiry Date shall be
the date the Option Holder ceases to hold such position; OR 

	(b) 	
      Ceasing to be Employed or Engaged - In the
      event that the Option Holder holds his or her Option as an Employee or
      Consultant and such Option Holder ceases to hold such position other than
      by reason of death or Disability, the Expiry Date of the Option shall be,
      unless otherwise expressly provided for in the Option Certificate, the
      90th day following the date the Option Holder ceases to hold such
      position, unless the Option Holder ceases to hold such position as a
      result of:

	 	(i) 	
      termination for cause;

	 	 	 
	 	(ii) 	
      resigning or terminating his or her position;
or

	 	 	 
	 	(iii) 	
      an order made by any Regulatory Authority having
      jurisdiction to so order;

in which case the Expiry Date shall be the date the Option
Holder ceases to hold such position. 

In the event that the Option Holder ceases to hold the position
of Executive, Employee or Consultant for which the Option was originally
granted, but comes to hold a different position as an Executive, Employee or
Consultant prior to the expiry of the Option, the Committee may, in its sole
discretion, choose to permit the Option to stay in place for that Option Holder
with such Option then to be treated as being held by that Option Holder in his
or her new position and such will not be considered to be an amendment to the
Option in question requiring the consent of the Option Holder under section 9.2
of this Plan. Notwithstanding anything else contained herein, in no case will an
Option be exercisable later than the Expiry Date of the Option. 

5.5 Vesting of Option and Acceleration

The vesting schedule for an Option, if any, shall be determined
by the Committee and shall be set out in the Option Certificate issued in
respect of the Option. The Committee may elect to accelerate the vesting 

- 12 - 

schedule of one or more Options in connection with a Triggering
Event in accordance with Section 11.4 of this Plan, and such acceleration will
not be considered an amendment to the Option in question requiring the consent
of the Option Holder under section 9.2 of this Plan. 

5.6 Additional Terms 

Subject to all applicable Regulatory Rules and all necessary
Regulatory Approvals, the Committee may attach additional terms and conditions
to the grant of a particular Option, such terms and conditions to be set out in
the Option Certificate. The Option Certificates will be issued for convenience
only, and in the case of a dispute with regard to any matter in respect thereof,
the provisions of this Plan and the records of the Company shall prevail over
the terms and conditions in the Option Certificate, save and except as noted
below. 

5.7 U.S. Option Holders 

Any Option granted under the Plan to an Option Holder who is a
citizen or resident of the United States (a “U.S. Option Holder”) within the
meaning of the U.S. Internal Revenue Code of 1986, as amended, (the “Code”),
will be an incentive stock option (an “ISO”) within the meaning of Section 422
of the Code if so designated by the Company in the Option Certificate evidencing
such Option. No provision of this Plan, as it may be applied to a U.S. Option
Holder with respect to Options which are designated as ISOs, shall be construed
so as to be inconsistent with any provision of Section 422 of the Code. Grants
of Options to U.S. Option Holders which are not designated as an ISO in the
Option Certificate evidencing such Option or otherwise do not qualify as ISOs
will be treated as nonstatutory stock options for U.S. federal tax purposes.
Notwithstanding anything in this Plan contained to the contrary, the following
provisions shall apply to ISOs granted to each U.S. Option Holder: 

	(a) 	
      subject to adjustment as provided for in this Plan, the
      number of Shares which will be available for granting ISOs will not exceed
      the number of Shares available for purchase pursuant to Options granted
      pursuant to the Plan set out in Section 4.2;

	 	 
	(b) 	
      ISOs shall only be granted to individual U.S. Option
      Holders who are, at the time of grant, “employees” of the Company within
      the meaning of the Code (or of any “subsidiary” of the Company within the
      meaning of section 424(f) of the Code);

	 	 
	(c) 	
      the aggregate fair market value (determined as of the
      time an ISO is granted) of the Shares subject to ISOs exercisable for the
      first time by a U.S. Option Holder during any calendar year under this
      Plan (and all other plans of the Company, any “subsidiary” of the Company
      within the meaning of Section 424(f) of the Code and any “parent” of the
      Company within the meaning of Section 424(e) of the Code) shall not exceed
      One Hundred Thousand Dollars in U.S. funds (U.S.$100,000);

	 	 
	(d) 	
      the Exercise Price per Share for each ISO granted to a
      U.S. Option Holder pursuant to this Plan shall be not less than fair
      market value of one Share on the Grant Date, as determined in good faith
      by the Committee at such time ;

	 	 
	(e) 	
      the Exercise Period of an ISO shall not exceed ten (10)
      years from the Grant Date;

	 	 
	(f) 	
      if a U.S. Option Holder who has been granted an ISO
      ceases to be an “employee” of the Company within the meaning of the Code
      (or of any “subsidiary” of the Company within the meaning of section
      424(f) of the Code) for any reason other than the death, Disability or a
      reason described in clause (i), (ii), or (iii) of Section 5.4(a) or
      5.4(b), such ISO may be exercised (to the extent such ISO was exercisable
      on the date of termination) by such U.S. Option Holder for a period of
      three (3) months after the date of termination (but in no event beyond the
      term of such ISO);

- 13 - 

	(g) 	
      if any U.S. Option Holder to whom an ISO is to be granted
      under the Plan at the time of the grant of such ISO is the owner, directly
      or constructively, of shares possessing more than ten percent (10%) of the
      total combined voting power of all classes of shares of the Company, then
      the following special provisions shall be applicable to the ISO granted to
      such Option Holder:

	 	(i) 	
      the Exercise Price per Share with respect to such ISO
      shall not be less than one hundred ten percent (110%) of the fair market
      value of one Share on the Grant Date, as determined in good faith by the
      Committee at such time; and

	 	 	 
	 	(ii) 	
      the Exercise Period of such ISO shall not exceed five (5)
      years from the Grant Date;

	(h) 	
      no ISO may be granted hereunder to a U.S. Option Holder
      following the expiration of ten (10) years after the date on which this
      Plan is adopted by the Board or the date on which the Plan is approved by
      the shareholders of the Company, whichever is earlier; and

	 	 
	(i) 	
      no ISO granted to a U.S. Option Holder under the Plan
      shall become exercisable unless and until the Plan shall have been
      approved by the shareholders of the Company. In the event that this Plan
      is not approved by the shareholders of the Company within twelve (12)
      months before or after the date on which this Plan is adopted by the
      Board, any ISO will automatically be deemed to be a nonstatutory stock
      option.

SECTION 6 
TRANSFERABILITY OF OPTIONS 

6.1 Non-transferable 

Except as provided otherwise in this Section 6, Options are
non-assignable and non-transferable. 

6.2 Death of Option Holder 

In the event of the Option Holder’s death, any Options held by
such Option Holder shall pass to the Personal Representative of the Option
Holder and shall be exercisable by the Personal Representative on or before the
date which is the earlier of six months following the date of death and the
applicable Expiry Date. 

6.3 Disability of Option Holder

If the employment or engagement of an Option Holder as an
Employee or Consultant or the position of an Option Holder as a director or
officer of the Company or a Subsidiary is terminated by the Company by reason of
such Option Holder’s Disability, any Options held by such Option Holder shall be
exercisable by such Option Holder or by the Personal Representative on or before
the date which is the earlier of six months following the termination of
employment, engagement or appointment as a director or officer and the
applicable Expiry Date. 

6.4 Disability and Death of Option
Holder 

If an Option Holder has ceased to be employed, engaged or
appointed as a director or officer of the Company or a Subsidiary by reason of
such Option Holder’s Disability and such Option Holder dies within six months
after the termination of such engagement, any Options held by such Option Holder
that could have been exercised immediately prior to his or her death shall pass
to the Personal Representative of such Option Holder and shall be exercisable by
the Personal Representative on or before the date which is the earlier of six
months following the death of such Option Holder and the applicable Expiry Date.
For 

- 14 - 

purposes of this Section 6.4, with respect to any U.S.
Participant holding ISOs, “Disability” means, with respect to any such U.S.
Participant, that such U.S. Participant is unable to engage in any substantial
gainful activity by reason of any medically determinable physical or mental
impairment that can be expected to result in death or that has lasted, or can be
expected to last, for a continuous period of not less than twelve (12) months.
The preceding definition of the term “Disability” is intended to comply with,
and will be interpreted consistently with, sections 22(e)(3) and 422(c)(6) of
the Code. 

6.5 Vesting 

Unless the Committee determines otherwise, Options held by or
exercisable by a Personal Representative shall, during the period prior to their
termination, continue to vest in accordance with any vesting schedule to which
such Options are subject. 

6.6 Deemed Non-Interruption of
Engagement 

Employment or engagement by the Company shall be deemed to
continue intact during any military or sick leave or other bona fide leave of
absence if the period of such leave does not exceed 90 days or, if longer, for
so long as the Option Holder’s right to re-employment or re-engagement by the
Company is guaranteed either by statute or by contract. If the period of such
leave exceeds 90 days and the Option Holder’s re-employment or re-engagement is
not so guaranteed, then his or her employment or engagement shall be deemed to
have terminated on the ninety-first day of such leave. 

SECTION 7 
EXERCISE OF OPTION 

7.1 Exercise of Option 

An Option may be exercised only by the Option Holder or the
Personal Representative of any Option Holder. An Option Holder or the Personal
Representative of any Option Holder may exercise an Option in whole or in part
at any time and from time to time during the Exercise Period up to the Expiry
Time on the Expiry Date by delivering to the Administrator the required Exercise
Notice, the applicable Option Certificate and a certified cheque or bank draft
payable to the Company in an amount equal to the aggregate Exercise Price of the
Shares then being purchased pursuant to the exercise of the Option. Except where
not permitted by the TSX, where an Option otherwise would expire during a
Black-Out period or during a Black-Out Expiration Term, the Expiry Date of such
Option will automatically be deemed to be extended to the end of the applicable
Black-Out Expiration Term. 

7.2 Issue of Share Certificates

As soon as reasonably practicable following the receipt of the
Exercise Notice, the Administrator shall cause to be delivered to the Option
Holder a certificate for the Shares so purchased. If the number of Shares so
purchased is less than the number of Shares subject to the Option Certificate
surrendered, the Administrator shall also provide a new Option Certificate for
the balance of Shares available under the Option to the Option Holder concurrent
with delivery of the Share Certificate. 

7.3 No Rights as Shareholder 

Until the date of the issuance of the certificate for the
Shares purchased pursuant to the exercise of an Option, no right to vote or
receive dividends or any other rights as a shareholder shall exist with respect
to such Shares, notwithstanding the exercise of the Option, unless the Committee
determines otherwise. In the event of any dispute over the date of the issuance
of the certificates, the decision of the Committee shall be final, conclusive
and binding.

SECTION 10
CONDITIONS PRECEDENT TO ISSUANCE OF
OPTIONS AND SHARES 

10.1 Compliance with Laws 

An Option shall not be granted or exercised, and Shares shall
not be issued pursuant to the exercise of any Option, unless the grant and
exercise of such Option and the issuance and delivery of such Shares comply with
all applicable Regulatory Rules, and such Options and Shares will be subject to
all applicable trading restrictions in effect pursuant to such Regulatory Rules
and the Company shall be entitled to legend the Option Certificates and the

10.2 Obligation to Obtain Regulatory
Approvals 

In administering this Plan, the Committee will seek any
Regulatory Approvals which may be required. The Committee will not permit any
Options to be granted without first obtaining the necessary Regulatory Approvals
unless such Options are granted conditional upon such Regulatory Approvals being
obtained. The Committee will make all filings required with the Regulatory

No Option granted will be exercisable or binding on the Company
unless and until all necessary Regulatory Approvals have been obtained. The
Committee shall be entitled to amend this Plan and the Options granted hereunder
in order to secure any necessary Regulatory Approvals and such amendments will
not require the consent of the Option Holders under section 9.2 of this Plan.

10.3 Inability to Obtain Regulatory
Approvals 

The Company’s inability to obtain Regulatory Approval from any
applicable Regulatory Authority, which Regulatory Approval is deemed by the
Committee to be necessary to complete the grant of Options hereunder, the
exercise of those Options or the lawful issuance and sale of any Shares pursuant
to such Options, shall relieve the Company of any liability with respect to the
failure to complete such transaction. 

10.4 U.S. Regulatory Approvals 

Section 10.2 of this Plan shall not be interpreted to require
the Company to register the Shares issuable pursuant to this Plan under the U.S.
Securities Act or under the securities laws of any state of the United States;
provided, however, that no Options to purchase Shares may be granted in the
United States or to or for the benefit of a U.S. Person, and no Options to
purchase Shares may be exercised in the United States or by or on behalf of a
U.S. Person, unless such Shares have been registered under the U.S. Securities
Act and the securities laws of all applicable states of the United States, or
exemptions from such registration requirements are available. The Company may
require such additional information, representations, warranties and covenants
from an Option Holder, in the Option Certificate, exercise form or otherwise, as
the Company deems necessary or appropriate in order to establish compliance with
all applicable provisions of the U.S. Securities Act and the securities laws of
any state of the United States. 

SECTION 11 
ADJUSTMENTS AND TERMINATION 

11.1 Termination of Plan 

Subject to any necessary Regulatory Approvals, the Committee
may terminate or suspend the Plan. 

- 19 - 

11.2 No Grant During Suspension of Plan

No Option may be granted during any suspension, or after
termination, of the Plan. Suspension or termination of the Plan shall not,
without the consent of the Option Holder, alter or impair any rights or
obligations under any Option previously granted. 

11.3 Alteration in Capital Structure

If there is a material alteration in the capital structure of
the Company and the Shares are consolidated, subdivided, converted, exchanged,
reclassified or in any way substituted for or affected, the Committee shall make
such adjustments to this Plan and to the Options then outstanding under this
Plan as the Committee determines to be appropriate and equitable under the
circumstances, so that the proportionate interest of each Option Holder shall,
to the extent practicable, be maintained as before the occurrence of such event.
Such adjustments may include, without limitation: 

	(a) 	
      a change in the number or kind of shares of the Company
      covered by such Options; and

	 	 
	(b) 	
      a change in the Exercise Price payable per Share
      provided, however, that the aggregate Exercise Price applicable to the
      unexercised portion of existing Options shall not be altered, it being
      intended that any adjustments made with respect to such Options shall
      apply only to the Exercise Price per Share and the number of Shares
      subject thereto.

For purposes of this section 11.3, and without limitation,
neither: 

	(c) 	
      the issuance of additional securities of the Company in
      exchange for adequate consideration (including services); nor

	 	 
	(d) 	
      the conversion of outstanding securities of the Company
      into Shares shall be deemed to be material alterations of the capital
      structure of the Company.

Any adjustment made to any Options pursuant to this section
11.3 shall not be considered an amendment requiring the Option Holder’s consent
for the purposes of Section 9.2 of this Plan. 

11.4 Triggering Events 

Subject to the Company complying with section 11.5 and any
necessary Regulatory Approvals and notwithstanding any other provisions of this
Plan or any Option Certificate, the Committee may, without the consent of the
Option Holder or Holders in question: 

	(a) 	
      accelerate the vesting of all or any portion of the
      unvested Options then issued and outstanding under the Plan;

	 	 
	(b) 	
      cause all or a portion of any of the Options granted
      under the Plan to terminate in connection with a Triggering Event;
    or

	 	 
	(c) 	
      cause all or a portion of any of the Options granted
      under the Plan to be exchanged for incentive stock options of another
      corporation in connection with a Triggering Event in such ratio and at
      such exercise price as the Committee deems appropriate, acting reasonably.
      Any adjustment with respect to the Exercise Price for and number of Common
      Shares subject to an Option granted to a U.S. Participant pursuant to this
      section 11.4(c) will be made so as to comply with, and not create any
      adverse consequences under, sections 424 and 409A of the
  Code.

- 20 - 

Such acceleration, termination or exchange shall not be
considered an amendment requiring the Option Holder’s consent for the purpose of
section 9.2 of the Plan.

11.5 Notice of Termination by Triggering
Event 

In the event that the Committee wishes to cause all or a
portion of any of the Options granted under this Plan to terminate in accordance
with Section 11.4, it must give written notice to the Option Holders in question
not less than 14 days prior to the date on which such Options are to terminate
so as to permit the Option Holder the opportunity to exercise the vested portion
of the Options prior to such termination. 

SECTION 12 
CALIFORNIA OPTION GRANTS 

12.1 Application of this Section

Notwithstanding any other provision of this Plan, the
provisions of sections 12.2 through 12.6 of this Plan shall apply to any Option

securities possessing more than 10% of the total combined voting power of all
classes of securities of the Company or its parent or subsidiaries possessing
voting power, the Exercise Price of the Option shall not be less than 110% of
the Market Value of the Shares as of the Grant Date. 

12.3 Minimum Vesting Schedule 

The Option must become vested and exercisable at a rate of at
least 20% of the number of Shares underlying the Option per year, with the first

The Expiry Date of the Option shall not be later than the tenth
anniversary of the Grant Date.

least the earlier of the Expiry Date originally provided for in the Option, or
the applicable date set forth below: 

	(a) 	
      if the Option Holder is terminated for cause as defined
      by applicable law, the date of termination ;

	 	 
	(b) 	
      if the Option Holder’s termination is caused by the
      Option Holder’s death or Disability, six months from the date of
      termination; or

	 	 
	(c) 	
      in all other cases, thirty days from the date of
      termination.

- 21 - 

12.6 Additional Shareholder Approval

Unless the holders of a majority of the Company’s outstanding
securities entitled to vote have approved this Plan within 12 months before or
after the date this Plan is adopted, any Option granted to a resident of the
State of California that is subject to the provisions of this Section 12 shall
automatically be rescinded, without any liability to the Company. No Option
granted subject to the provisions of this SECTION 12 shall be exercisable until
such shareholder approval has been obtained.

Each Term Loan shall be made as part of a Borrowing consisting of Term Loans
made by the Lenders ratably in accordance with their respective Term Loan
Commitments. The failure of any Lender to make any Term Loan required to be made
by it shall not relieve any other Lender of its obligations hereunder;
provided that the Term Loan Commitments of the Lenders are several and no
Lender shall be responsible for any other Lender’s failure to make Term Loans as
required.

Each Lender at its option may make any Term Loan by causing any branch or

Agent will make such Term Loans available to the Borrower by promptly crediting
the amounts so received to the Proceeds Account. 

                         (b)     
Unless the Administrative Agent shall have received notice from a Lender prior
to the proposed date of any Borrowing that such Lender will not make available
to the Administrative Agent such Lender’s share of such Borrowing, the
Administrative Agent may assume that such Lender has made such share available
on such date in accordance with paragraph (a) of this Section and may, in
reliance upon such assumption, make available to the Borrower a corresponding
amount. In such event, if a Lender has not in fact made its share of the
applicable Borrowing available to the Administrative Agent, then the applicable
Lender and

the Borrower severally agree to pay to the Administrative Agent
forthwith on demand such corresponding amount with interest thereon, for each

but excluding the date of payment to the Administrative Agent, at (i) in the
case of such Lender, the rate determined by the Administrative Agent in
accordance with banking industry rules on interbank compensation or (ii) in the

promises to pay to the Administrative Agent for the account of each Lender: 

                        
(a)      the then unpaid principal amount of the A Term
Loan in 15 (fifteen) equal installments on each Principal Payment Date; and 

                         (b)     
the then unpaid principal amount of the B Term Loan (if any) on the final
Principal Payment Date, provided that if the Deferred Payment Trigger
Event has occurred, then the B Term Loan shall be payable in equal installments
on each of the Principal Payment Dates remaining for the A Term Loan (after
giving effect to the payment of the Deferred Amounts).

For the avoidance of doubt and by way of illustration (x) if
the B Term Loan was outstanding and the Deferred Payment Trigger Event occurred
prior to the first Principal Payment Date, then the B Term Loan would be
amortized over the first 13 (thirteen) Principal Payment Dates, since the last
two installments of the A Term Loan (defined as the “Deferred Payments”) shall
have already been paid, and (y) if the Deferred Payment Trigger Event occurs
after the first Principal Payment Date but prior to the second Principal Payment
Date, then the B Term Loan would be amortized over the next 12 (twelve)
Principal Payment Dates.

          SECTION
2.7. Evidence of Debt.

                         (a)     
Each Lender shall maintain in accordance with its usual practice an account or
accounts evidencing the indebtedness of the Borrower to such Lender resulting
from each Term Loan made by such Lender, including the amounts of principal and
interest payable to such Lender hereunder. 

                         (b)     
The Administrative Agent shall maintain accounts in which it shall record (i)
the amount of each Term Loan made hereunder and the Interest Period applicable
thereto, (ii) the amount of any principal or interest due and payable or to
become due and payable from 

- 19 - 

the Borrower to each Lender hereunder and (iii) the amount of
any sum received by the Administrative Agent hereunder for the account of the
Lenders and each Lender’s share thereof. 

                         (c)     
The entries made in the accounts maintained pursuant to paragraph (a) or (b) of
this Section shall be prima facie evidence of the existence and
amounts of the obligations recorded therein; provided that the failure of
any Lender or the Administrative Agent to maintain such accounts or any error
therein shall not in any manner affect the obligation of the Borrower to repay
the Term Loans in accordance with the terms of this Agreement. 

                         (d)     
Any Lender may request that Term Loans made by it be evidenced by a promissory
note. In such event, the Borrower shall prepare, execute and deliver to such
Lender a promissory note payable to the order of such Lender (or, if requested
by such Lender, to such Lender and its registered assigns) and in a form
approved by the Administrative Agent. Thereafter, the Term Loans evidenced by
such promissory note and interest thereon shall at all times (including after
assignment pursuant to Section 10.4) be represented by one or more promissory
notes in such form payable to the order of the payee named therein (or, if such
promissory note is a registered note, to such payee and its registered assigns).

          SECTION
2.8. Optional Prepayments of Term Loans. The Borrower shall have the
right at any time and from time to time to prepay any Term Loan in whole or in
part, provided that: 

                        
(a)      the Borrower shall notify the Administrative
Agent in writing of any prepayment hereunder not later than 11:00 a.m., New York
City time, at least five Business Days before the date of prepayment; each such
notice shall be irrevocable and shall specify the prepayment date and the
principal amount of each Term Loan or portion thereof to be prepaid; promptly
following receipt of any such notice, the Administrative Agent shall advise the
Lenders of the contents thereof;

                        
(b)      each prepayment shall be applied (i)
first, to the Deferred Payments until such payments have been paid in
full, (ii) second to installments of the B Term Loan (if any) in inverse
order of maturity until paid in full, and (iii) third, to installments of
the A Term Loan in inverse order of maturity until paid in full; prepayments
shall be accompanied by accrued interest to the extent required by Section 2.11
and any break funding payments required by Section 2.14; 

                        
(c)      the Debt Service Reserve Account is fully
funded; 

                        
(d)      the Borrower shall be in compliance with the
financial covenants set forth in Section 6.10 after giving effect to any such
prepayment (calculated on a proforma basis with respect to the Historical Test
Period and Future Test Period for the Test Date most recently ended); and 

                        
(e)      so long as such prepayment is made with the
proceeds of internally generated funds (and not a refinancing) then no
prepayment penalty shall apply; provided that a prepayment penalty in an
amount set forth on the following schedule shall apply with respect to any
prepayment made with proceeds of other than internally generated funds: 

- 20 - 

  	Period 

        
	Percentage of Principal Amount Prepaid 

        

	Closing Date through but excluding the second anniversary
      of the Closing Date 	3.5% 
	Second anniversary date of the Closing Date to but
      excluding the third anniversary of the Closing Date 	2.5% 
	Third anniversary date of the Closing Date to but excluding
      the fourth anniversary of the Closing Date 	1.5% 
	From and after the fourth anniversary of the Closing Date
    	1.0% 

          SECTION
2.9. Mandatory Prepayments.

                         (a)     
Excess Cash Flow. After the termination of the Availability Period, on
each date of delivery of financial statements as required by Sections 5.01(a)
and (b), the Borrower shall deliver to the Administrative Agent an Excess Cash
Flow Certificate for the fiscal quarter most recently ended and shall
simultaneously prepay outstanding Term Loans in the aggregate principal amount
equal to the amount of 80% of Excess Cash Flow indicated on such certificate,
provided that, after the Deferred Payment Trigger Event, the Borrower shall be
thereafter obliged to prepay outstanding Term Loans in the aggregate principal
amount equal to 40% of Excess Cash Flow as indicated on such certificate. The
Administrative Agent shall notify the Borrower, within 10 Business Days after
receipt of such certificate, whether it validates and approves such certificate,
and, if it does not validate and approve the certificate, advise the Borrower of
the amount of the Excess Cash Flow as calculated by the Administrative Agent. In
the absence of manifest error on the part of the Administrative Agent, the
Borrower shall adjust the amount to be paid by it on the following Principal
Payment Date by the amount necessary to take account of the discrepancy in such
the certificate, as certified by the Administrative Agent. Any such prepayment
shall be applied in accordance with clause (e) hereof. 

                         
(b)      Dispositions. The Borrower shall prepay
the Term Loans in an amount equal to 100% of the Net Cash Proceeds of any
Disposition or series of Dispositions by any Loan Party or any Subsidiary of a
Loan Party pursuant to Section 6.3(a)(iii) generating Net Cash Proceeds in
excess of $250,000 in the aggregate after the Closing Date. Each such prepayment

- 21 - 

shall be due promptly upon receipt by the such Person of such
Net Cash Proceeds and shall be applied as set forth in clause (e) below.
Notwithstanding the foregoing, the Borrower shall not be required to apply any
such proceeds in accordance with clause (e) to the extent that the Borrower
advises the Administrative Agent at the time of the relevant Disposition that
the Borrower intends to use the Net Cash Proceeds thereof to finance one or more
Operating Costs or Project Development Costs permitted by this Agreement, and
such Net Cash Proceeds are in fact so applied (or contractually committed to be
applied) to such expenditures within 180 days of such Disposition (it being
understood that Net Cash Proceeds shall be deemed to be utilized in the same
order in which they are received. Any such Net Cash Proceeds which are not
applied (or contractually committed to be applied) within such 180 day period as
required by the immediately preceding sentence shall forthwith be applied in
accordance with clause (e). Notwithstanding the foregoing, the Borrower shall
not be required to prepay any proceeds realized form the sale of any
Dispositions generated from the sale of assets exclusively related to the Coyote
Springs or Mimbres sites. In addition, the Borrower agrees that the sale of any
drilling equipment no longer used in the business of the Borrower shall be
considered to be Disposition under Section 6.3(a)(iii) .

                        
(c)      Casualty Events. The Borrower shall
prepay the Term Loans in an amount equal to 100% of the Net Cash Proceeds
received by any Loan Party or any Subsidiary of a Loan Party in connection with
any Casualty Event or series of Casualty Events generating Net Cash Proceeds in
excess of $1,000,000 in the aggregate for any fiscal year. Each such prepayment
shall be due promptly upon receipt by such Person of such Net Cash Proceeds and
shall be applied as set forth in clause (e) below. Notwithstanding the
foregoing, the Borrower shall not be required to apply any such proceeds in
accordance with clause (e) to the extent that the Company advises the
Administrative Agent at the time of the relevant Casualty Event that it intends
to use Net Cash Proceeds thereof to finance the replacement or repair of such
affected property, and such Net Cash Proceeds are in fact so applied (or
contractually committed to be applied) to such affected Property within 360 days
of receipt thereof (it being understood that Net Cash Proceeds shall be deemed
to be utilized in the same order in which they are received). Any such Net Cash
Proceeds which are not applied (or contractually committed to be applied) within
such 360 day period as required by the immediately preceding sentence shall
forthwith be applied as set forth in clause (e) below. 

                        
(d)      Debt Issuances. The Borrower shall
prepay the Term Loans in an amount equal to 100% of the Net Cash Proceeds
received by the Borrower or any Subsidiary in connection with any Debt Issuance.
Each such prepayment shall be due promptly upon receipt by such Person of such
Net Cash Proceeds and shall be applied as set forth in clause (e) below. 

                        
(e)      Application. Any such prepayment shall
be applied (i) first, to the Deferred Payments until such payments have
been paid in full, (ii) second to installments of the B Term Loan (if
any) in inverse order of maturity until paid in full, and (iii) third, to
installments of the A Term Loan in inverse order of maturity until paid in full.

          SECTION
2.10. Fees.

                         (a)     
The Borrower agrees to pay to the Administrative Agent for the account of each
Lender a facility fee, which shall accrue at 0.250% per annum on the daily
amount of the 

- 22 - 

unused Term Loan Commitment of such Lender during the
Availability Period, subject to the last sentence hereof. Accrued facility fees
shall be payable in arrears on the last day of March, June, September and
December of each year and on the date on which the Term Loan Commitments
terminate, commencing on the first such date to occur after the date hereof. All
facility fees shall be computed on the basis of a year of 360 days and shall be
payable for the actual number of days elapsed (including the first day but
excluding the last day). Such fees shall be payable on an amount of unused
commitments for each day equal to the amount of unused Commitments set forth in
the table below minus the amount of Term Loans outstanding on such
day:

  	Period 

        
	Amount of 

        unused 
Commitments 
	From the Closing Date through the last day of September,
      2007 	$ 3,000,000 
	October 2007 	7,500,000 
	November 2007 	12,500,000 
	December 2007 	16,000,000 
	January 2008 	20,500,000 
	February 2008 	22,000,000 
	March 2008 	23,000,000 
	April 2008 through the end of the Availability Period 	25,000,000

For purposes of illustration, (a) if Term Loans in an amount in
excess of $9,000,000 were outstanding on September 15, 2007, no such fee would
be payable on such day, and (b) if Term Loans in an amount of $2,000,000 were
outstanding on September 15, 2007, such fee would be payable in respect of
$1,000,000 in unused Term Loan Commitments on such day.

                         (b)     
All fees payable hereunder shall be paid on the dates due, in immediately
available funds, to the Administrative Agent for distribution, in the case of
facility fees and participation fees, to the Lenders. Fees paid shall not be
refundable under any circumstances. 

- 23 - 

          SECTION
2.11. Interest.

                              (a)     
The aggregate principal amount of all outstanding A Term Loans and B Term Loans
(if any) shall bear interest from the date such Term Loan is made until the date
the principal of such Term Loan is repaid at an annual rate equal the LIBOR Rate
for the Interest Period in effect for such Term Loan plus the Applicable Margin
for such A Term Loan or B Term Loan, respectively. 

                              (b)     
Notwithstanding the foregoing, upon any Event of Default, all principal amounts
hereunder shall bear interest, after as well as before judgment, at a rate per
annum equal to 3% plus the rate otherwise applicable to such Term Loan as
provided in the preceding paragraph of this Section. 

                              (c)     
Accrued interest on each Term Loan shall be payable in arrears on each Interest
Payment Date; provided that (i) interest accrued pursuant to paragraph
(b) of this Section shall be payable on demand, and (ii) in the event of any
prepayment of any Term Loan, accrued interest on the principal amount prepaid
shall be payable on the date of such prepayment. Notwithstanding the foregoing,
(x) for each Interest Payment Date prior to the first Principal Payment Date,
any interest payable with respect to the A Term Loans on such Interest Payment
Date shall be capitalized and shall increase the unpaid principal amount of the
A Term Loans, and (y) for each Interest Payment Date prior to the Deferred
Payment Trigger Event, any interest payable with respect to the B Term Loans on
such Interest Payment Date shall be capitalized and shall increase the unpaid
principal amount of the B Term Loans. 

                              (d)     
The applicable LIBOR Rate shall be determined by the Administrative Agent, and
such determination shall be conclusive absent manifest error. 

          SECTION
2.12. Alternate Rate of Interest. If prior to the commencement of any
Interest Period for any Term Loan: 

                              (a)     
the Administrative Agent determines (which determination shall be conclusive
absent manifest error) that adequate and reasonable means do not exist for
ascertaining the LIBOR Rate for such Interest Period; or 

                              (b)     
the Administrative Agent is advised by the Required Lenders that the LIBOR Rate
for such Interest Period will not adequately and fairly reflect the cost to such
Lenders (or Lender) of making or maintaining their Term Loans (or its Term Loan)
included in such Borrowing for such Interest Period; 

then the Administrative Agent shall give notice thereof to the
Borrower and the Lenders by telephone or telecopy as promptly as practicable
thereafter and, until the Administrative Agent notifies the Borrower and the
Lenders that the circumstances giving rise to such notice no longer exist, (i)
no borrowing request shall be effective, and (ii) the Borrower and the Lenders
shall enter into negotiations in good faith with a view to establish a
satisfactory alternative basis for computing interest on the Term Loans. 

          SECTION
2.13. Increased Costs.

- 24 - 

                        
(a)      If any Change in Law shall: 

                         (i)     
impose, modify or deem applicable any reserve, special deposit or similar
requirement against assets of, deposits with or for the account of, or credit
extended by, any Lender; or 

                         (ii)     
impose on any Lender or the London interbank market any other condition
affecting this Agreement or Term Loans made by such Lender; 

and the result of any of the foregoing shall be to increase the
cost to such Lender of making or maintaining any Term Loan (or of maintaining
its obligation to make Term Loans) or to reduce the amount of any sum received
or receivable by such Lender hereunder (whether of principal, interest or
otherwise), then the Borrower will pay to such Lender, such additional amount or
amounts as will compensate such Lender for such additional costs incurred or
reduction suffered. 

                         (b)     
If any Lender determines that any Change in Law regarding capital requirements
has or would have the effect of reducing the rate of return on such Lender’s
capital or on the capital of such Lender’s holding company, if any, as a
consequence of this Agreement or the Term Loans made by, such Lender to a level
below that which such Lender or such Lender’s holding company could have
achieved but for such Change in Law (taking into consideration such Lender’s
policies and the policies of such Lender’s or holding company with respect to
capital adequacy), then from time to time the Borrower will pay to such Lender,
as the case may be, such additional amount or amounts as will compensate such
Lender or such Lender’s holding company for any such reduction suffered. 

                         (c)     
A certificate of a Lender setting forth the amount or amounts necessary to
compensate such Lender or its holding company, as the case may be, as specified
in paragraph (a) or (b) of this Section shall be delivered to the Borrower and
shall be conclusive absent manifest error. The Borrower shall pay such Lender,
as the case may be, the amount shown as due on any such certificate within 10
days after receipt thereof. 

                         (d)     
Failure or delay on the part of any Lender to demand compensation pursuant to
this Section shall not constitute a waiver of such Lender’s right to demand such
compensation; provided that the Borrower shall not be required to
compensate a Lender pursuant to this Section for any increased costs or
reductions incurred more than 270 days prior to the date that such Lender
notifies the Borrower of the Change in Law giving rise to such increased costs
or reductions and of such Lender’s intention to claim compensation therefor;
provided further that, if the Change in Law giving rise to such
increased costs or reductions is retroactive, then the 270-day period referred
to above shall be extended to include the period of retroactive effect thereof.

          SECTION
2.14. Break Funding Payments. In the event of (a) the payment of any
principal of any Term Loan other than on the last day of an Interest Period
applicable thereto (including as a result of an Event of Default), (b) the
failure to borrow any Term Loan on the date specified in any notice delivered
pursuant hereto, then, in each such event, the Borrower shall compensate each
Lender for the loss, cost and expense attributable to such event. Such loss,
cost or expense to any Lender shall be deemed to include an amount determined by
such 

- 25 - 

Lender to be the excess, if any, of (i) the amount of interest
which would have accrued on the principal amount of such Term Loan had such
event not occurred, at the LIBOR Rate that would have been applicable to such
Term Loan, for the period from the date of such event to the last day of the
then current Interest Period therefor (or, in the case of a failure to borrow,
for the period that would have been the Interest Period for such Term Loan),
over (ii) the amount of interest which would accrue on such principal amount for
such period at the interest rate which such Lender would bid were it to bid, at
the commencement of such period, for dollar deposits of a comparable amount and
period from other banks in the eurodollar market. A certificate of any Lender
setting forth any amount or amounts that such Lender is entitled to receive
pursuant to this Section shall be delivered to the Borrower and shall be
conclusive absent manifest error. The Borrower shall pay such Lender the amount
shown as due on any such certificate on demand. 

          SECTION
2.15. Taxes.

                         (a)     
Any and all payments by or on account of any obligation of the Borrower
hereunder shall be made free and clear of any present and future tax liability
and without deduction for any Indemnified Taxes or Other Taxes; provided
that if the Borrower shall be required to deduct any Indemnified Taxes or Other
Taxes from such payments, then (i) the sum payable shall be increased as
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section) the Administrative
Agent or Lender (as the case may be) receives an amount equal to the sum it
would have received had no such deductions been made, (ii) the Borrower shall
make such deductions and (iii) the Borrower shall pay the full amount deducted
to the relevant Governmental Authority in accordance with applicable law. 

                         (b)     
In addition, the Borrower shall pay any Other Taxes to the relevant Governmental
Authority in accordance with applicable law. 

                         (c)     
The Borrower shall indemnify the Administrative Agent and each Lender, within 10
days after written demand therefor, for the full amount of any Indemnified Taxes
or Other Taxes paid by the Administrative Agent or such Lender, as the case may
be, on or with respect to any payment by or on account of any obligation of the
Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or
asserted on or attributable to amounts payable under this Section) and any
penalties, interest and reasonable expenses arising therefrom or with respect
thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or
legally imposed or asserted by the relevant Governmental Authority. A
certificate as to the amount of such payment or liability delivered to the
Borrower by a Lender or by the Administrative Agent on its own behalf or on
behalf of a Lender, shall be conclusive absent manifest error. 

                         (d)     
As soon as practicable after any payment of Indemnified Taxes or Other Taxes by
the Borrower to a Governmental Authority, the Borrower shall deliver to the
Administrative Agent the original or a certified copy of a receipt issued by
such Governmental Authority evidencing such payment, a copy of the return
reporting such payment or other evidence of such payment reasonably satisfactory
to the Administrative Agent. 

- 26 - 

                         (e)     
Any Foreign Lender that is entitled to an exemption from or reduction of
withholding tax under the law of the jurisdiction in which the Borrower is
located, or any treaty to which such jurisdiction is a party, with respect to
payments under this Agreement shall deliver to the Borrower (with a copy to the
Administrative Agent), at the time or times prescribed by applicable law, such
properly completed and executed documentation prescribed by applicable law or
reasonably requested by the Borrower as will permit such payments to be made
without withholding or at a reduced rate. 

                         (f)    
If the Administrative Agent or a Lender determines, in its sole discretion, that
it has received a refund of any Taxes or Other Taxes as to which it has been
indemnified by the Borrower or with respect to which the Borrower has paid
additional amounts pursuant to this Section 2.15, it shall pay over such refund
to the Borrower (but only to the extent of indemnity payments made, or
additional amounts paid, by the Borrower under this Section 2.15 with respect to
the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket
expenses of the Administrative Agent or such Lender and without interest (other
than any interest paid by the relevant Governmental Authority with respect to
such refund); provided, that the Borrower, upon the request of the
Administrative Agent or such Lender, agrees to repay the amount paid over to the
Borrower (plus any penalties, interest or other charges imposed by the relevant
Governmental Authority) to the Administrative Agent or such Lender in the event
the Administrative Agent or such Lender is required to repay such refund to such
Governmental Authority. This Section shall not be construed to require the
Administrative Agent or any Lender to make available its tax returns (or any
other information relating to its taxes which it deems confidential) to the
Borrower or any other Person. 

          SECTION
2.16. Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

                         (a)     
The Borrower shall make each payment required to be made by it hereunder
(whether of principal, interest or fees, or of amounts payable under Section
2.13, 2.14 or 2.15, or otherwise) prior to 12:00 noon, New York City time, on
the date when due, in immediately available funds, without set-off or
counterclaim. Any amounts received after such time on any date may, in the
discretion of the Administrative Agent, be deemed to have been received on the
next succeeding Business Day for purposes of calculating interest thereon. All
such payments shall be made into account number 2000193000423 maintained by the
Administrative Agent with Wachovia Bank, N.A. located in New York, New York,
except that payments pursuant to Sections 2.13, 2.14, 2.15 and 10.3 shall be
made directly to the Persons entitled thereto. The Administrative Agent shall
distribute any such payments received by it for the account of any other Person
to the appropriate recipient promptly following receipt thereof. If any payment
hereunder shall be due on a day that is not a Business Day, the date for payment
shall be extended to the next succeeding Business Day, and, in the case of any
payment accruing interest, interest thereon shall be payable for the period of
such extension. All payments hereunder shall be made in dollars. 

                         (b)     
If at any time insufficient funds are received by and available to the
Administrative Agent to pay fully all amounts of principal, interest and fees
then due hereunder, such funds shall be applied (i) first, towards payment of
interest and fees then due hereunder, ratably among the parties entitled thereto
in accordance with the amounts of interest and fees then due to such parties,
and (ii) second, towards payment of principal then due hereunder, 

- 27 - 

ratably among the parties entitled thereto in accordance with
the amounts of principal then due to such parties. 

                         (c)     
If any Lender shall, by exercising any right of set-off or counterclaim or
otherwise, obtain payment in respect of any principal of or interest on any of
its Term Loans resulting in such Lender receiving payment of a greater
proportion of the aggregate amount of its Term Loans and accrued interest
thereon than the proportion received by any other Lender, then the Lender
receiving such greater proportion shall purchase (for cash at face value)
participations in the Term Loans of other Lenders to the extent necessary so
that the benefit of all such payments shall be shared by the Lenders ratably in
accordance with the aggregate amount of principal of and accrued interest on
their respective Term Loans; provided that (i) if any such participations
are purchased and all or any portion of the payment giving rise thereto is
recovered, such participations shall be rescinded and the purchase price
restored to the extent of such recovery, without interest, and (ii) the
provisions of this paragraph shall not be construed to apply to any payment made
by the Borrower pursuant to and in accordance with the express terms of this
Agreement or any payment obtained by a Lender as consideration for the
assignment of or sale of a participation in any of its Term Loans to any
assignee or participant, other than to the Loan Parties or any Affiliate thereof
(as to which the provisions of this paragraph shall apply). The Borrower
consents to the foregoing and agrees, to the extent it may effectively do so
under applicable law, that any Lender acquiring a participation pursuant to the
foregoing arrangements may exercise against the Borrower rights of set-off and
counterclaim with respect to such participation as fully as if such Lender were
a direct creditor of the Borrower in the amount of such participation. 

                         (d)     
Unless the Administrative Agent shall have received notice from the Borrower
prior to the date on which any payment is due to the Administrative Agent for
the account of the Lenders hereunder that the Borrower will not make such
payment, the Administrative Agent may assume that the Borrower has made such
payment on such date in accordance herewith and may, in reliance upon such
assumption, distribute to the Lenders, as the case may be, the amount due. In
such event, if the Borrower has not in fact made such payment, then each of the
Lenders severally agrees to repay to the Administrative Agent forthwith on
demand the amount so distributed to such Lender with interest thereon, for each
day from and including the date such amount is distributed to it to but
excluding the date of payment to the Administrative Agent, at the greater of the
Federal Funds Effective Rate and a rate determined by the Administrative Agent
in accordance with banking industry rules on interbank compensation. 

                         (e)     
If any Lender shall fail to make any payment required to be made by it pursuant
to Section 2.4(a), 2.16(d) or 10.3(c) , then the Administrative Agent
may, in its discretion (notwithstanding any contrary provision hereof), apply
any amounts thereafter received by the Administrative Agent for the account of
such Lender to satisfy such Lender’s obligations under such Sections until all
such unsatisfied obligations are fully paid. 

          SECTION
2.17. Mitigation Obligations. If any Lender requests compensation under
Section 2.13, or if the Borrower is required to pay any additional amount to any
Lender or any Governmental Authority for the account of any Lender pursuant to
Section 2.15, then such Lender shall use reasonable efforts to designate a
different lending office for funding or booking 

- 28 - 

its Term Loans hereunder or to assign its rights and
obligations hereunder to another of its offices, branches or affiliates, if, in
the judgment of such Lender, such designation or assignment (i) would eliminate
or reduce amounts payable pursuant to Section 2.13 or 2.15, as the case may be,
in the future and (ii) would not subject such Lender to any unreimbursed cost or
expense and would not otherwise be disadvantageous to such Lender. The Borrower
hereby agrees to pay all reasonable costs and expenses incurred by any Lender in
connection with any such designation or assignment. 

ARTICLE III. 
REPRESENTATIONS AND
WARRANTIES 

          Each
Loan Party represents and warrants to the Lenders that: 

          SECTION
3.1. Status and Power. The Borrower is a corporation duly incorporated
and validly existing under the laws of the State of Delaware. The Guarantor is a
corporation duly incorporated and validly existing under the laws of the State
of Nevada. Each Loan Party is duly qualified, registered or licensed in all
jurisdictions where such qualification, registration or licensing is required
except where the lack of such qualification, registration or licensing could not
reasonably be expected to have a Material Adverse Effect. Each Loan Party has
all requisite corporate capacity, power and authority to own, hold under license
or lease its properties, to carry on its business as now conducted and to
otherwise enter into, and carry out the Transactions. None of the Loan
Parties nor any of their property has any immunity from jurisdiction of any
court or from any legal process (whether through service, notice, attachment
prior to judgment, attachment in aid of execution, execution or otherwise). 

          SECTION

corporate or otherwise, has been taken to authorize the execution, delivery and
performance by each Loan Party of the Loan Documents to which it is a party.

is a party. The Loan Documents to which each Loan Party is a party are legal,
valid and binding obligations of such Loan Party, enforceable against such Loan
Party by the other parties thereto in accordance with their respective terms,
except to the extent that the enforceability thereof may be limited by
applicable bankruptcy, insolvency, moratorium, reorganization, fraudulent
conveyance and other similar laws of general application limiting the
enforcement of creditors’ rights generally and the fact that the courts may deny
the granting or enforcement of equitable remedies. 

          SECTION

Party of the Loan Documents and Material Contracts to which it is a party, and
the consummation of the transactions contemplated herein and therein (i) do not
conflict with, result in any breach or violation of, or constitute a default
under the terms, conditions or provisions of (A) the articles of incorporation
or by-laws (or comparable constituting documents) of, or any shareholder
agreement relating to, any Loan Party or (B) any law, regulation, judgment,
decree or order binding on or applicable to any Loan Party or to which its
property is subject or any agreement, lease, license, permit or other instrument
to which any Loan Party is a party or is otherwise bound or by which any Loan
Party benefits or to which any of its property is subject except, in each case,
to the extent that such conflict does not and could not reasonably be expected
to have a Material Adverse Effect and (ii) do not require the consent or
approval of any 

- 29 - 

Governmental Authority or any other Person which has not been
obtained and provided to the Administrative Agent. 

          SECTION

date hereof with respect to the Project and (b) taken as a whole, the cash flow
calculations contained in the Financial Model are based on assumptions which, at
the date hereof, are fair and reasonable in light of the Borrower’s expectations
and information with respect to the Project. 

          SECTION

purpose of effecting any of the foregoing; 

                         (i)     
a Loan Party shall become unable, admit in writing its inability or fail
generally to pay its debts as they become due; 

                         (j)     
one or more judgments for the payment of money in an aggregate amount in excess

creditor to attach or levy upon any assets of a Loan Party to enforce any such

- 46 - 

then, and in every such event (other than an event with respect
to the Borrower described in clause (g) or (h) of this Article), and at any time
thereafter during the continuance of such event, the Administrative Agent may,
and at the request of the Required Lenders shall, by notice to the Borrower,
take either or both of the following actions, at the same or different times:
(i) terminate the Term Loan Commitments, and thereupon the Term Loan Commitments
shall terminate immediately, and (ii) declare the Term Loans then outstanding to
be due and payable in whole (or in part, in which case any principal not so
declared to be due and payable may thereafter be declared to be due and
payable), and thereupon the principal of the Term Loans so declared to be due
and payable, together with accrued interest thereon and all fees and other
obligations of the Borrower accrued hereunder, shall become due and payable
immediately, without presentment, demand, protest or other notice of any kind,
all of which are hereby waived by the Borrower; and in case of any event with
respect to the Borrower described in clause (g) or (h) of this Article, the Term
Loan Commitments shall automatically terminate and the principal of the Term
Loans then outstanding, together with accrued interest thereon and all fees and
other obligations of the Borrower accrued hereunder, shall automatically become
due and payable, without presentment, demand, protest or other notice of any
kind, all of which are hereby waived by the Borrower. 

ARTICLE VIII. 
THE ADMINISTRATIVE AGENT

          Each
of the Lenders hereby irrevocably appoints the Administrative Agent as its agent
and authorizes the Administrative Agent to take such actions on its behalf and
to exercise such powers as are delegated to the Administrative Agent by the
terms hereof, together with such actions and powers as are reasonably incidental
thereto. 

          The
bank serving as the Administrative Agent hereunder shall have the same rights
and powers in its capacity as a Lender as any other Lender and may exercise the
same as though it were not the Administrative Agent, and such bank and its
Affiliates may accept deposits from, lend money to and generally engage in any
kind of business with the Loan Parties or other Affiliate thereof as if it were
not the Administrative Agent hereunder. 

          The
Administrative Agent shall not have any duties or obligations except those
expressly set forth herein. Without limiting the generality of the foregoing,
(a) the Administrative Agent shall not be subject to any fiduciary or other
implied duties, regardless of whether a Default has occurred and is continuing,
(b) the Administrative Agent shall not have any duty to take any discretionary
action or exercise any discretionary powers, except discretionary rights and
powers expressly contemplated hereby that the Administrative Agent is required
to exercise in writing as directed by the Required Lenders (or such other number
or percentage of the Lenders as shall be necessary under the circumstances as
provided in Section 10.2), and (c) except as expressly set forth herein, the
Administrative Agent shall not have any duty to disclose, and shall not be
liable for the failure to disclose, any information relating to any Loan Party
that is communicated to or obtained by the bank serving as Administrative Agent
or any of its Affiliates in any capacity. The Administrative Agent shall not be
liable for any action taken or not taken by it with the consent or at the
request of the Required Lenders (or such other number or percentage of the
Lenders as shall be necessary under the circumstances as provided in Section
10.2) or in the absence of its own gross negligence or willful misconduct. The
Administrative Agent shall be 

- 47 - 

deemed not to have knowledge of any Default unless and until
written notice thereof is given to the Administrative Agent by the Borrower or a
Lender, and the Administrative Agent shall not be responsible for or have any
duty to ascertain or inquire into (i) any statement, warranty or representation
made in or in connection with this Agreement, (ii) the contents of any
certificate, report or other document delivered hereunder or in connection
herewith, (iii) the performance or observance of any of the covenants,
agreements or other terms or conditions set forth herein, (iv) the validity,
enforceability, effectiveness or genuineness of this Agreement or any other
agreement, instrument or document, or (v) the satisfaction of any condition set
forth in Article IV or elsewhere herein, other than to confirm receipt of items
expressly required to be delivered to the Administrative Agent. 

          The
Administrative Agent shall be entitled to rely upon, and shall not incur any
liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing believed by it to be genuine
and to have been signed or sent by the proper Person. The Administrative Agent
also may rely upon any statement made to it orally or by telephone and believed
by it to be made by the proper Person, and shall not incur any liability for
relying thereon. The Administrative Agent may consult with legal counsel (who
may be counsel for the Borrower), independent accountants and other experts
selected by it, and shall not be liable for any action taken or not taken by it
in accordance with the advice of any such counsel, accountants or experts. 

          The
Administrative Agent may perform any and all its duties and exercise its rights
and powers by or through any one or more sub-agents appointed by the
Administrative Agent. The Administrative Agent and any such sub-agent may
perform any and all its duties and exercise its rights and powers through their
respective Related Parties. The exculpatory provisions of the preceding
paragraphs shall apply to any such sub-agent and to the Related Parties of the
Administrative Agent and any such sub-agent, and shall apply to their respective
activities in connection with the syndication of the Term Loan provided for
herein as well as activities as Administrative Agent. 

          Subject
to the appointment and acceptance of a successor Administrative Agent as
provided in this paragraph, the Administrative Agent may resign at any time by
notifying the Lenders and the Borrower. Upon any such resignation, the Required
Lenders shall have the right, in consultation with the Borrower, to appoint a
successor. If no successor shall have been so appointed by the Required Lenders
and shall have accepted such appointment within 30 days after the retiring
Administrative Agent gives notice of its resignation, then the retiring
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent which shall be a bank with an office in New York, New York,
or an Affiliate of any such bank. Upon the acceptance of its appointment as
Administrative Agent hereunder by a successor, such successor shall succeed to
and become vested with all the rights, powers, privileges and duties of the
retiring Administrative Agent, and the retiring Administrative Agent shall be
discharged from its duties and obligations hereunder. The fees payable by the
Borrower to a successor Administrative Agent shall be the same as those payable
to its predecessor unless otherwise agreed between the Borrower and such
successor. After the Administrative Agent’s resignation hereunder, the
provisions of this Article and Section 10.3 shall continue in effect for the
benefit of such retiring Administrative Agent, its sub-agents and their
respective Related Parties in 

- 48 - 

respect of any actions taken or omitted to be taken by any of
them while it was acting as Administrative Agent. 

          Each
Lender acknowledges that it has, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. Each Lender also acknowledges that it
will, independently and without reliance upon the Administrative Agent or any
other Lender and based on such documents and information as it shall from time
to time deem appropriate, continue to make its own decisions in taking or not
taking action under or based upon this Agreement, any related agreement or any
document furnished hereunder or thereunder. 

ARTICLE IX. 

  GUARANTY

          SECTION
9.1. Guaranty. Guarantor hereby unconditionally and irrevocably
guarantees to each of the Lenders the punctual payment, performance in full and
observance when due, whether at stated maturity, by acceleration or otherwise,
of the Borrower’s Obligations (the “Guaranteed Obligations”) now or
hereafter existing under any Loan Document, whether for principal, interest
(including, without limitation, all interest that accrues after the commencement
of any bankruptcy proceeding of the Borrower, whether or not constituting an
allowed claim in such bankruptcy proceeding), fees, commissions, expense
reimbursements, indemnifications or otherwise, and agrees to pay any and all
costs, fees and expenses (including reasonable counsel fees and expenses)
incurred by the Administrative Agent and the Lenders in enforcing any rights
under the guaranty set forth in this Article IX, as they become due from time to
time in accordance with the express provisions of the Loan Documents. The
Administrative Agent shall be entitled to enforce this Guarantee for its own
benefit and the ratable benefit of the Lenders and each Lender shall be entitled
to enforce this Guarantee for its own benefit through the Administrative Agent
in respect of the Guaranteed Obligations owing to it but without duplication.
Without limiting the generality of the foregoing, Guarantor’s liability shall
extend to all amounts that constitute part of the Guaranteed Obligations and
would be owed by the Borrower to the Administrative Agent and the Lenders under
any Loan Document but for the fact that they are unenforceable or not allowable
due to the existence of an bankruptcy proceeding involving the Borrower. 

          SECTION
9.2. Guaranty Absolute. Guarantor guarantees that the Guaranteed
Obligations will be paid strictly in accordance with the terms of the Loan
Documents, regardless of any law, regulation or order now or hereafter in effect
in any jurisdiction affecting any of such terms or the rights of the
Administrative Agent or the Lenders with respect thereto. The obligations of
Guarantor under this Article IX are independent of the Guaranteed Obligations,
and a separate action or actions may be brought and prosecuted against Guarantor
to enforce such obligations, irrespective of whether any action is brought
against the Borrower or whether the Borrower is joined in any such action or
actions. The liability of Guarantor under this Article IX constitutes a primary
obligation, and not a contract of surety, and shall be irrevocable, absolute and
unconditional irrespective of, and Guarantor hereby irrevocably waives any
defenses it may now or hereafter have in any way relating to, any or all of the
following: 

- 49 - 

                         (a)     
any lack of validity or enforceability of any Loan Document or any agreement or
instrument relating thereto; 

                         (b)     
any change in the time, manner or place of payment of, or in any other term of,
all or any of the Guaranteed Obligations, or any other amendment or waiver of or
any consent to departure from any Loan Document, including, without limitation,
any increase in the Guaranteed Obligations resulting from the extension of
additional credit to the Borrower or otherwise 

                         (c)     
any taking, exchange, release, subordination or non-perfection of any of the
Collateral, or any taking, release or amendment or waiver of or consent to
departure from any other guaranty, for all or any of the Guaranteed Obligations;

                         (d)     
any change, restructuring or termination of the corporate structure or existence
of any of the Loan Parties; or 

                         (e)     
except for payment in full of the Guaranteed Obligations, any other circumstance
(including, without limitation, any statute of limitations) or any existence of
or reliance on any representation by the Administrative Agent or the Lenders
that might otherwise constitute a defense available to, or a discharge of, any
of the Loan Parties or any other guarantor or surety. 

This Article IX shall continue to be effective or be
reinstated, as the case may be, if at any time any payment of any of the
Guaranteed Obligations is rescinded or must otherwise be returned by the
Administrative Agent or the Lenders or any other Person upon the insolvency,
bankruptcy or reorganization of the Borrower or otherwise (and whether as a
result of any demand, settlement, litigation or otherwise), all as though such
payment had not been made. 

          SECTION
9.3. Waiver. Guarantor hereby waives promptness, diligence, notice
of acceptance and any other notice with respect to any of the Guaranteed
Obligations and this Article IX and any requirement that the Administrative
Agent or the Lenders exhaust any right or take any action against any of the
Loan Parties or any other Person or any Collateral. Guarantor acknowledges that
it will receive direct and indirect benefits from the financing arrangements
contemplated herein and that the waiver set forth in this Section 9.3 is
knowingly made in contemplation of such benefits. Guarantor hereby waives any
right to revoke this Article IX, and acknowledges that this Article IX is
continuing in nature and applies to all Guaranteed Obligations, whether existing
now or in the future. 

          SECTION
9.4. Continuing Guaranty; Assignments. This Article IX is a
continuing guaranty and shall (a) remain in full force and effect until payment
in full of the Guaranteed Obligations, (b) be binding upon Guarantor, its
successors and assigns and (c) inure to the benefit of and be enforceable by the
Administrative Agent and the Lenders and their successors, pledgees, transferees
and assigns. Without limiting the generality of the foregoing clause (c), any
Lender may pledge, assign or otherwise transfer all or any portion of its rights
and obligations under this agreement (including, without limitation, all or any
portion of its Term Loan Commitment and its Term Loans) to any other Person, and
such other Person shall 

- 50 - 

thereupon become vested with all the benefits in respect
thereof granted such Lender herein or otherwise. 

          SECTION
9.5. Subrogation. Guarantor shall not exercise any rights that it
may now or hereafter acquire against the Borrower or any other guarantor that
arise from the existence, payment, performance or enforcement of Guarantor’s
obligations under this Article IX, including, without limitation, any right of
subrogation, reimbursement, exoneration, contribution or indemnification and any
right to participate in any claim or remedy of the Administrative Agent or the
Lenders against any of the Loan Parties or any other guarantor or any
Collateral, whether or not such claim, remedy or right arises in equity or under
contract, statute or common law, including, without limitation, the right to
take or receive from any of the Loan Parties or any other guarantor, directly or
indirectly, in cash or other property or by set-off or in any other manner,
payment or security solely on account of such claim, remedy or right, unless and
until payment in full of the Guaranteed Obligations; provided, that Guarantor
shall not have any rights hereunder against the Borrower if all or any portion
of the Guaranteed Obligations shall have been satisfied with proceeds from the
exercise of remedies in respect of the Equity Interest of the Borrower pursuant
to any Security Document. In addition, unless and until payment in full of the
Guaranteed Obligations, any indebtedness of the Borrower now or hereafter held
by Guarantor is subordinated in right of payment to the Guaranteed Obligations,
and any such indebtedness collected or received by Guarantor after an Event of
Default has occurred and is continuing but prior to payment in full of the
Guaranteed Obligations, shall be held in trust for Administrative Agent on
behalf of the Administrative Agent and the Lenders and shall forthwith be paid
over to Administrative Agent for the benefit of itself and the Lenders to be
credited and applied against the Guaranteed Obligations. If any amount shall be
paid to Guarantor in violation of the immediately preceding two sentences, such
amount shall be held in trust for the benefit of the Administrative Agent and
the Lenders and shall forthwith be paid to Administrative Agent for the benefit
of the Administrative Agent and the Lenders to be credited and applied to the
Guaranteed Obligations and all other amounts payable under this Article IX,
whether matured or unmatured, in accordance with the terms of this Agreement, or
to be held as Security for any Guaranteed Obligations or other amounts payable
under this Article IX thereafter arising. Upon payment in full of the Guaranteed
Obligations, the Administrative Agent and the Lenders will, at the Guarantor’s
request and expense, execute and deliver to the Guarantor appropriate documents,
without recourse and without representation or warranty, necessary to evidence
the transfer by subrogation to Guarantor of an interest in the Guaranteed
Obligations resulting from such payment by Guarantor. 

          SECTION
9.6. Maximum Obligations. Notwithstanding any provision herein
contained to the contrary, Guarantor’s liability with respect to the Obligations
shall be limited to an amount not to exceed, as of any date of determination,
the amount that could be claimed by the Administrative Agent and the Lenders
from Guarantor without rendering such claim voidable or avoidable under Section
548 of the Bankruptcy Code or under any applicable state Uniform Fraudulent
Transfer Act, Uniform Fraudulent Conveyance Act or similar statute or common
law.

communications provided for herein shall be in writing and shall be delivered by
hand or overnight courier service, mailed by certified or registered mail or
sent by telecopy, as follows: 

                         (i)

                         (ii)

                         (iii)     
if to any other Lender, to it at its address (or telecopy number) as indicted to

                         (b)     
Notices and other communications to the Lenders hereunder may be delivered or
furnished by electronic communications pursuant to procedures approved by the
Administrative Agent; provided that the foregoing shall not apply to notices
pursuant to Article II unless otherwise agreed by the Administrative Agent and
the applicable Lender. The Administrative Agent or the Borrower may, in its
discretion, agree to accept notices and other communications to it hereunder by
electronic communications pursuant to procedures approved by it; provided that
approval of such procedures may be limited to particular notices or
communications. 

                         (c)     
Any party hereto may change its address or telecopy number for notices and other
communications hereunder by notice to the other parties hereto. All notices and
other communications given to any party hereto in accordance with the provisions
of this Agreement shall be deemed to have been given on the date of receipt.

          SECTION
10.2. Waivers; Amendments.

                         (a)     
No failure or delay by the Administrative Agent or any Lender in exercising any
right or power hereunder shall operate as a waiver thereof, nor shall any single
or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
and remedies of the Administrative Agent and the Lenders hereunder are
cumulative and are not exclusive of any rights or remedies that they would
otherwise have. No waiver of any provision of this Agreement or consent to any
departure by the Borrower therefrom shall in any event be effective unless the
same shall be permitted by paragraph (b) of this Section, and then such waiver
or consent shall be effective only in the specific instance and for the purpose
for which given. Without limiting the generality of the foregoing, the making of
a Term Loan shall not be construed as a waiver of any Default, regardless of
whether the Administrative Agent or any Lender may have had notice or knowledge
of such Default at the time. 

- 52 - 

                         (b)     
Neither this Agreement nor any provision hereof may be waived, amended or
modified except pursuant to an agreement or agreements in writing entered into
by the Borrower and the Required Lenders or by the Borrower and the
Administrative Agent with the consent of the Required Lenders; provided
that no such agreement shall (i) increase the Term Loan Commitment of any Lender
without the written consent of such Lender, (ii) reduce the principal amount of
the Term Loans or reduce the rate of interest thereon, or reduce any fees
payable hereunder, without the written consent of each Lender affected thereby,
(iii) postpone the scheduled date of payment of the principal amount of the Term
Loans, or any interest thereon, or any fees payable hereunder, or reduce the
amount of, waive or excuse any such payment, or postpone the scheduled date of
expiration of any Term Loan Commitment, without the written consent of each
Lender affected thereby, (iv) change Section 2.16(b) or (c) in a manner that
would alter the pro rata sharing of payments required thereby, without the
written consent of each Lender, or (v) change any of the provisions of this
Section or the definition of “Required Lenders” or any other provision hereof
specifying the number or percentage of Lenders required to waive, amend or
modify any rights hereunder or make any determination or grant any consent
hereunder, without the written consent of each Lender; provided
further that no such agreement shall amend, modify or otherwise affect
the rights or duties of the Administrative Agent hereunder without the prior
written consent of the Administrative Agent. 

          SECTION
10.3. Expenses; Indemnity; Damage Waiver.

                         (a)     
The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the
Administrative Agent and its Affiliates, including the reasonable fees, charges
and disbursements of any advisor or counsel for the Administrative Agent or any
Lender (provided that the Borrower shall not be required to pay for more
than one counsel to the Administrative Agent and the Lenders, other than special
local counsel), in connection with the syndication of the Term Loans provided
for herein (which in any event shall be conducted in accordance with Section
10.4(b)), the due diligence, preparation, negotiation and administration of this
Agreement or any amendments, modifications or waivers of the provisions hereof
(whether or not the transactions contemplated hereby or thereby shall be
consummated) and the other Loan Documents and (ii) all out-of-pocket expenses
incurred by the Administrative Agent or any Lender, including the fees, charges
and disbursements of any advisor or counsel for the Administrative Agent or any
Lender, in connection with the enforcement or protection of its rights in
connection with this Agreement, including its rights under this Section, or in
connection with the Term Loans made, including all such out-of-pocket expenses
incurred during any workout, restructuring or negotiations in respect of the
Term Loans. 

                         (b)     
The Borrower shall indemnify the Administrative Agent and each Lender, and each
Related Party of any of the foregoing Persons (each such Person being called an
“Indemnitee”) against, and hold each Indemnitee harmless from, any and
all losses, claims, damages, liabilities and related expenses, including the
fees, charges and disbursements of any counsel for any Indemnitee, incurred by
or asserted against any Indemnitee arising out of, in connection with, or as a
result of (i) the execution or delivery of this Agreement or any agreement or
instrument contemplated hereby, the performance by the parties hereto of their
respective obligations hereunder or the consummation of the Transactions or any
other transactions contemplated hereby, (ii) any Term Loan or the use of the
proceeds therefrom, (iii) any actual or alleged presence or release of Hazardous
Materials on or from any property 

- 53 - 

owned or operated by the Loan Parties, or any Environmental
Liability related in any way to the Loan Parties, or (iv) any actual or
prospective claim, litigation, investigation or proceeding relating to any of
the foregoing, whether based on contract, tort or any other theory and
regardless of whether any Indemnitee is a party thereto; provided that
such indemnity shall not, as to any Indemnitee, be available to the extent that
such losses, claims, damages, liabilities or related expenses are determined by
a court of competent jurisdiction by final and nonappealable judgment to have
resulted from the gross negligence or willful misconduct of such Indemnitee.

                         (c)     
To the extent that the Borrower fails to pay any amount required to be paid by
it to the Administrative Agent under paragraph (a) or (b) of this Section, each
Lender severally agrees to pay to the Administrative Agent, such Lender’s
Applicable Percentage (determined as of the time that the applicable
unreimbursed expense or indemnity payment is sought) of such unpaid amount;
provided that the unreimbursed expense or indemnified loss, claim,
damage, liability or related expense, as the case may be, was incurred by or
asserted against the Administrative Agent in its capacity as such. 

                         (d)     
To the extent permitted by applicable law, the Borrower shall not assert, and
hereby waives, any claim against any Indemnitee, on any theory of liability, for
special, indirect, consequential or punitive damages (as opposed to direct or
actual damages) arising out of, in connection with, or as a result of, this
Agreement or any agreement or instrument contemplated hereby, the Transactions
or any Term Loan or the use of the proceeds thereof. 

                         (e)     
All amounts due under this Section shall be payable promptly after written
demand therefor. 

          SECTION
10.4. Successors and Assigns.

                         (a)     
The provisions of this Agreement shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and assigns permitted
hereby, except that (i) the Borrower may not assign or otherwise transfer any of
its rights or obligations hereunder without the prior written consent of each
Lender (and any attempted assignment or transfer by the Borrower without such
consent shall be null and void) and (ii) no Lender may assign or otherwise
transfer its rights or obligations hereunder except in accordance with this
Section. Nothing in this Agreement, expressed or implied, shall be construed to
confer upon any Person (other than the parties hereto, their respective
successors and assigns permitted hereby, Participants (to the extent provided in
paragraph (c) of this Section) and, to the extent expressly contemplated hereby,
the Related Parties of each of the Administrative Agent and the Lenders) any
legal or equitable right, remedy or claim under or by reason of this Agreement.

                         (b)     
(i)      Subject to the conditions set forth in
paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Term Loan Commitment and the Term Loans at the time owing to it)
with the prior written consent (such consent not to be unreasonably withheld)
of: 

                         (A)     
the Borrower, provided that no consent of the Borrower shall be required
for an assignment to a Lender, an Affiliate of a Lender, or, if an 

- 54 - 

Event of Default has occurred and is
continuing, any other assignee; provided that any such assignment to an
Affiliate shall in all cases be subject to Section 2.17; 

                         (B)     
the Administrative Agent, provided that no consent of the Administrative
Agent shall be required for an assignment of any Term Loan Commitment to an
assignee that is a Lender with a Term Loan Commitment immediately prior to
giving effect to such assignment; and 

                         (ii)     
Assignments shall be subject to the following additional conditions: 

                         (A)     
except in the case of an assignment to a Lender or an Affiliate of a Lender or
an assignment of the entire remaining amount of the assigning Lender’s Term Loan
Commitment or Term Loans, the amount of the Term Loan Commitment or Term Loans
of the assigning Lender subject to each such assignment (determined as of the
date the Assignment and Assumption with respect to such assignment is delivered
to the Administrative Agent) shall not be less than $5,000,000 unless each of
the Borrower and the Administrative Agent otherwise consent, provided
that no such consent of the Borrower shall be required if an Event of Default
has occurred and is continuing; 

                         (B)     
  each partial assignment shall be made as an assignment of a proportionate part
  of all the assigning Lender’s rights and obligations under this Agreement,
  provided that this clause shall not be construed to prohibit the assignment
  of a proportionate part of all the assigning Lender’s rights and obligations
  in respect of one type of Term Loan Commitment or Term Loans;

                         (C)     
the parties to each assignment shall execute and deliver to the Administrative
Agent an Assignment and Assumption, together with a processing and recordation
fee of $3,500; and 

                         (D)     
the assignee, if it shall not be a Lender, shall designate to the Administrative
Agent one or more Credit Contacts to whom all syndicate-level information (which
may contain material non-public information about the Loan Parties and their
related parties or their respective securities) will be made available and who
may receive such information in accordance with the assignee’s compliance
procedures and applicable laws, including Federal and state securities laws.

                         (iii)     
Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of
this Section, from and after the effective date specified in each Assignment and
Assumption the assignee thereunder shall be a party hereto and, to the extent of
the interest assigned by such Assignment and Assumption, have the rights and
obligations of a Lender under this Agreement, and the assigning Lender
thereunder shall, to the extent of the interest assigned by such Assignment and
Assumption, be released from its obligations under this Agreement (and, in the
case of an Assignment and Assumption covering all of the assigning Lender’s
rights and obligations under this 

- 55 - 

Agreement, such Lender shall cease to be a party hereto but
shall continue to be entitled to the benefits of Sections 2.13, 2.14, 2.15 and
10.3) . Any assignment or transfer by a Lender of rights or obligations under
this Agreement that does not comply with this Section 10.4 shall be treated for
purposes of this Agreement as a sale by such Lender of a participation in such
rights and obligations in accordance with paragraph (c) of this Section. 

                         (iv)     
The Administrative Agent, acting for this purpose as an agent of the Borrower,
shall maintain at one of its offices a copy of each Assignment and Assumption
delivered to it and a register for the recordation of the names and addresses of
the Lenders, and the Term Loan Commitment of, and principal amount of the Term
Loan Commitment or Term Loans owing to, each Lender pursuant to the terms hereof
from time to time (the “Register”). The entries in the Register shall be
conclusive, and the Borrower, the Administrative Agent and the Lenders may treat
each Person whose name is recorded in the Register pursuant to the terms hereof
as a Lender hereunder for all purposes of this Agreement, notwithstanding notice
to the contrary. The Register shall be available for inspection by the Borrower
and any Lender, at any reasonable time and from time to time upon reasonable
prior notice. 

                         (v)     
Upon its receipt of a duly completed Assignment and Assumption executed by an
assigning Lender and an assignee, the processing and recordation fee referred to
in paragraph (b) of this Section and any written consent to such assignment
required by paragraph (b) of this Section, the Administrative Agent shall accept
such Assignment and Assumption and record the information contained therein in
the Register; provided that if either the assigning Lender or the
assignee shall have failed to make any payment required to be made by it
pursuant to Section 2.5(c), 2.6(d) or (e), 2.7(b), 2.16(d) or 10.3(c), the
Administrative Agent shall have no obligation to accept such Assignment and
Assumption and record the information therein in the Register unless and until
such payment shall have been made in full, together with all accrued interest
thereon. No assignment shall be effective for purposes of this Agreement unless
it has been recorded in the Register as provided in this paragraph. 

                         (i)     
Any Lender may, without the consent of the Borrower or the Administrative Agent,
sell participations to one or more banks or other entities (a
“Participant”) in all or a portion of such Lender’s rights and
obligations under this Agreement (including all or a portion of its Term Loan
Commitment and the Term Loans owing to it); provided that (A) such
Lender’s obligations under this Agreement shall remain unchanged, (B) such
Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations and (C) the Borrower, the Administrative Agent
and the other Lenders shall continue to deal solely and directly with such
Lender in connection with such Lender’s rights and obligations under this
Agreement. Any agreement or instrument pursuant to which a Lender sells such a
participation shall provide that such Lender shall retain the sole right to
enforce this Agreement and to approve any amendment, modification or waiver of
any provision of this Agreement; provided that such agreement or
instrument may provide that such Lender will not, without the consent of the
Participant, agree to any amendment, modification or waiver 

- 56 - 

described in the first proviso to
Section 10.2(b) that affects such Participant. Subject to paragraph (c)(ii) of
this Section, the Borrower agrees that each Participant shall be entitled to the
benefits of Sections 2.13, 2.14 and 2.15 to the same extent as if it were a
Lender and had acquired its interest by assignment pursuant to paragraph (b) of
this Section. To the extent permitted by law, each Participant also shall be
entitled to the benefits of Section 10.8 as though it were a Lender, provided
such Participant agrees to be subject to Section 2.16(c) as though it were a
Lender. 

                         (ii)     
A Participant shall not be entitled to receive any greater payment under Section
2.13 or 2.15 than the applicable Lender would have been entitled to receive with
respect to the participation sold to such Participant, unless the sale of the
participation to such Participant is made with the Borrower’s prior written
consent. A Participant that would be a Foreign Lender if it were a Lender shall
not be entitled to the benefits of Section 2.17 unless the Borrower is notified
of the participation sold to such Participant and such Participant agrees, for
the benefit of the Borrower, to comply with Section 2.15(e) as though it were a
Lender. 

                         (c)     
Any Lender may at any time pledge or assign a security interest in all or any
portion of its rights under this Agreement to secure obligations of such Lender,
including without limitation any pledge or assignment to secure obligations to a
Federal Reserve Bank, and this Section shall not apply to any such pledge or
assignment of a security interest; provided that no such pledge or
assignment of a security interest shall release a Lender from any of its
obligations hereunder or substitute any such pledgee or assignee for such Lender
as a party hereto. 

          SECTION
10.5. Survival. All covenants, agreements, representations and warranties
made by the Borrower herein and in the certificates or other instruments
delivered in connection with or pursuant to this Agreement shall be considered
to have been relied upon by the other parties hereto and shall survive the
execution and delivery of this Agreement and the making of any Term Loans,
regardless of any investigation made by any such other party or on its behalf
and notwithstanding that the Administrative Agent or any Lender may have had
notice or knowledge of any Default or incorrect representation or warranty at
the time any credit is extended hereunder, and shall continue in full force and
effect as long as the principal of or any accrued interest on the Term Loans or
any fee or any other amount payable under this Agreement is outstanding and
unpaid and so long as the Term Loan Commitments have not expired or terminated.
The provisions of Sections 2.13, 2.14, 2.15 and 10.3 and Article VIII shall
survive and remain in full force and effect regardless of the consummation of
the transactions contemplated hereby, the repayment of the Term Loans and the
Term Loan Commitments or the termination of this Agreement or any provision
hereof. 

          SECTION
10.6. Counterparts; Integration; Effectiveness. This Agreement may be
executed in counterparts (and by different parties hereto on different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Agreement and any
separate letter agreements with respect to fees payable to the Administrative
Agent constitute the entire contract among the parties relating to the subject

- 57 - 

matter hereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof. Except
as provided in Section 4.1, this Agreement shall become effective when it shall
have been executed by the Administrative Agent and when the Administrative Agent
shall have received counterparts hereof which, when taken together, bear the
signatures of each of the other parties hereto, and thereafter shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns. Delivery of an executed counterpart of a signature page
of this Agreement by telecopy shall be effective as delivery of a manually
executed counterpart of this Agreement. 

          SECTION
10.7. Severability. Any provision of this Agreement held to be invalid,
illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity, illegality or unenforceability
without affecting the validity, legality and enforceability of the remaining
provisions hereof; and the invalidity of a particular provision in a particular
jurisdiction shall not invalidate such provision in any other jurisdiction. 

          SECTION
10.8. Right of Setoff. If an Event of Default shall have occurred and be
continuing, each Lender and each of its Affiliates is hereby authorized at any
time and from time to time, to the fullest extent permitted by law, to set off
and apply any and all deposits (general or special, time or demand, provisional
or final) at any time held and other obligations at any time owing by such
Lender or Affiliate to or for the credit or the account of the Borrower against
any of and all the obligations of the Borrower now or hereafter existing under
this Agreement or any Hedging Agreement held by such Lender, irrespective of
whether or not such Lender shall have made any demand under this Agreement or
such Hedging Agreement and although such obligations may be unmatured. The
rights of each Lender under this Section are in addition to other rights and
remedies (including other rights of setoff) which such Lender may have. 

          SECTION
10.9. Governing Law; Jurisdiction; Consent to Service of Process.

                         (a)     
This Agreement shall be construed in accordance with and governed by the law of
the State of New York. 

                         (b)     
The Borrower hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of the Supreme Court of the State of
New York sitting in New York County and of the United States District Court of
the Southern District of New York, and any appellate court from any thereof, in
any action or proceeding arising out of or relating to this Agreement, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in such New York State or,
to the extent permitted by law, in such Federal court. Each of the parties
hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Agreement shall affect any
right that the Administrative Agent or any Lender may otherwise have to bring
any action or proceeding relating to this Agreement against the Borrower or its
properties in the courts of any jurisdiction. 

                         (c)     
The Borrower hereby irrevocably and unconditionally waives, to the fullest
extent it may legally and effectively do so, any objection which it may now or
hereafter 

- 58 - 

have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement in any court referred to in
paragraph (b) of this Section. Each of the parties hereto hereby irrevocably
waives, to the fullest extent permitted by law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court. 

                         (d)     
Each party to this Agreement irrevocably consents to service of process in the
manner provided for notices in Section 10.1. Nothing in this Agreement will
affect the right of any party to this Agreement to serve process in any other
manner permitted by law. 

          SECTION
10.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING
TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON
CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK
TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER
PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. 

          SECTION
10.11. Headings. Article and Section headings and the Table of Contents
used herein are for convenience of reference only, are not part of this
Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Agreement. 

          SECTION
10.12. Confidentiality.

                         (a)     
Each of the Administrative Agent and the Lenders agrees to maintain the
confidentiality of the Information (as defined below), except that Information
may be disclosed (a) to its and its Affiliates’ directors, officers, employees
and agents, including accountants, legal counsel and other advisors (it being
understood that the Persons to whom such disclosure is made will be informed of
the confidential nature of such Information and instructed to keep such
Information confidential), (b) to the extent requested by any regulatory
authority, (c) to the extent required by applicable laws or regulations or by
any subpoena or similar legal process, (d) to any other party to this Agreement,
(e) in connection with the exercise of any remedies hereunder or any suit,
action or proceeding relating to this Agreement or the enforcement of rights
hereunder, (f) subject to an agreement containing provisions substantially the
same as those of this Section, to (i) any assignee of or Participant in, or any
prospective assignee of or Participant in, any of its rights or obligations
under this Agreement or (ii) any actual or prospective counterparty (or its
advisors) to any swap or derivative transaction relating to the Borrower and its
obligations, (g) with the consent of the Borrower or (h) to the extent such
Information (i) becomes publicly available other than as a result of a breach of
this Section or (ii) becomes available to the Administrative Agent or any Lender
on a nonconfidential basis from a source other than the Borrower. For the
purposes of this Section, “Information” means all information received
from the Borrower relating to the Borrower or its business, other than any such
information that is available to the Administrative Agent or any Lender on a

- 59 - 

nonconfidential basis prior to disclosure by the Borrower;
provided that, in the case of information received from the Borrower
after the date hereof, such information is clearly identified at the time of
delivery as confidential. Any Person required to maintain the confidentiality of
Information as provided in this Section shall be considered to have complied
with its obligation to do so if such Person has exercised the same degree of
care to maintain the confidentiality of such Information as such Person would
accord to its own confidential information. 

                         (b)     
EACH LENDER ACKNOWLEDGES THAT INFORMATION AS DEFINED IN SECTION 10.12(a)
FURNISHED TO IT PURSUANT TO THIS AGREEMENT MAY INCLUDE MATERIAL NON-PUBLIC
INFORMATION CONCERNING THE BORROWER AND ITS RELATED PARTIES OR THEIR RESPECTIVE
SECURITIES, AND CONFIRMS THAT IT HAS DEVELOPED COMPLIANCE PROCEDURES REGARDING
THE USE OF MATERIAL NON-PUBLIC INFORMATION AND THAT IT WILL HANDLE SUCH MATERIAL
NON-PUBLIC INFORMATION IN ACCORDANCE WITH THOSE PROCEDURES AND APPLICABLE LAW,
INCLUDING FEDERAL AND STATE SECURITIES LAWS. 

                         (c)     
ALL INFORMATION, INCLUDING REQUESTS FOR WAIVERS AND AMENDMENTS, FURNISHED BY THE
BORROWER OR THE ADMINISTRATIVE AGENT PURSUANT TO, OR IN THE COURSE OF
ADMINISTERING, THIS AGREEMENT WILL BE SYNDICATE-LEVEL INFORMATION, WHICH MAY
CONTAIN MATERIAL NON-PUBLIC INFORMATION ABOUT THE LOAN PARTIES AND THEIR RELATED
PARTIES OR THEIR RESPECTIVE SECURITIES. ACCORDINGLY, EACH LENDER REPRESENTS TO
THE BORROWER AND THE ADMINISTRATIVE AGENT THAT IT HAS IDENTIFIED A CREDIT
CONTACT WHO MAY RECEIVE INFORMATION THAT MAY CONTAIN MATERIAL NON-PUBLIC
INFORMATION IN ACCORDANCE WITH ITS COMPLIANCE PROCEDURES AND APPLICABLE LAW.

          SECTION
10.13. Interest Rate Limitation. Notwithstanding anything herein to the
contrary, if at any time the interest rate applicable to the Term Loans,
together with all fees, charges and other amounts which are treated as interest
on the Term Loans under applicable law (collectively the “Charges”),
shall exceed the maximum lawful rate (the “Maximum Rate”) which may be
contracted for, charged, taken, received or reserved by the Lender holding such
Term Loan in accordance with applicable law, the rate of interest payable in
respect of such Term Loan hereunder, together with all Charges payable in
respect thereof, shall be limited to the Maximum Rate and, to the extent lawful,
the interest and Charges that would have been payable in respect of such Term
Loan but were not payable as a result of the operation of this Section shall be
cumulated and the interest and Charges payable to such Lender in respect of
other Term Loans or periods shall be increased (but not above the Maximum Rate
therefor) until such cumulated amount, together with interest thereon to the
date of repayment, shall have been received by such Lender. 

          SECTION
10.14. Know Your Customer Requirements. Each Lender that is subject to
“know-your-customer” requirements of any Governmental Authority, hereby notifies
the Borrower that pursuant to such requirements, it is required to obtain,
verify and record information that identifies the Borrower, which information
includes the name and address of the 

- 60 - 

Borrower and other information that will allow such Lender to
identify the Borrower in accordance with such requirements. 

          SECTION
10.15. Consent Relating to Existing Copper Hedging Agreements. The
Borrower confirms that all of its rights under the Existing Copper Hedging
Agreements have been pledged, pursuant to the Security Documents, for the
benefit of the Administrative Agent and the Lenders, in order to secure amounts
owing under the Credit Agreement. The Borrower expressly agrees that if any
Event of Default shall occur and be continuing, the Administrative Agent, on
behalf of itself and the Lenders, may exercise any and all rights of the
Borrower under the Existing Copper Hedging Agreements, including, without
limitation the giving of notice to the Hedge Counterparty to terminate any
Existing Copper Hedging Agreements (to the extent required in order to pay the
outstanding Obligations in full) and to pay any amount then due and owing to the
Borrower under such Existing Copper Hedging Agreements directly to the
Administrative Agent to be applied in payment of the obligations under the
Credit Agreement.

          SECTION
10.16. Provisions Relating to B Term Loan. The Borrower agrees that if at
any time the Borrower would receive in excess of $2,200,000 (net of costs, fees
and expenses associated therewith) in proceeds from the termination of certain
copper price Hedging Agreements maturing from October 1, 2010 onwards, then it
shall terminate such Hedging Agreements in a manner satisfactory to the
Administrative Agent (a “Term Loan Conversion Event”), and the
following events shall occur: 

                        
(a)      Deposit to Debt Service Reserve
Account. The Borrower shall deposit $2,200,000 in Hedging Agreement proceeds
into the Debt Service Reserve Account. The balance of such proceeds, if any,
shall be deposited into the Proceeds Account. 

                         
(b)      Conversion of A Term Loan. The A Term
Loans shall automatically be separated into two separate tranches, the first
such tranche in an aggregate principal amount outstanding equal to the existing
A Term Loans minus the aggregate principal amount of the B Term Loans,
and the second such tranche in an aggregate principal amount outstanding equal
to $2,200,000 (such tranche, the “B Term Loans”). The amortization
payment required on each Principal Payment Date with respect to the A Term Loan
(prior to the Term Loan Conversion Event) shall be reduced pro-rata with respect
to each Principal Payment Date, and such amount shall be constitute the B Term
Loan.

                         
(c)      Further Assurances. Notwithstanding the
automatic nature of the conversion of the A Term Loan provided for in clause
(b), each party hereto agrees to execute such further instruments and documents
as the Administrative Agent shall reasonably request in order to effect the
conversion provided for above.

of the Effective Date set forth below and is entered into by and between
[Insert name of Assignor] (the “Assignor”) and [Insert name of
