 The Company has requested that The Industrial Development Board of
the City of Arab (the “Board”) issue its $1,000,000 aggregate principal amount of Industrial Development Revenue Bonds (Hyco Alabama Project) Series 2000 (the “Bonds”) in order to provide long-term financing for a portion of the
cost of acquiring, constructing and equipping manufacturing facilities for the manufacture of hydraulic cylinders, industrial tubing and other products (the “Project”). The Bonds will be issued pursuant to a Trust Indenture dated as of
September 1, 2000 (the “Indenture”) between the Board and Regions Bank (acting in such capacity, the “Trustee”). The Board will use the proceeds of the Bonds (i) to reimburse the Company for a portion of the sums

 As security for
the payment of the Bonds, the Company will cause Regions Bank (herein, in its capacity as issuer of the initial letter of credit referred to below, called the “Bank”), to issue an irrevocable letter of credit in favor of the Trustee in the
amount of (i) the aggregate principal amount of the Bonds, to enable the Trustee to pay the principal amount of the Bonds when due and to pay the principal portion of the purchase price of Bonds tendered (or deemed tendered) for purchase, plus
(ii) interest on the Bonds for a period of 36 days at the rate of 12% per annum, to enable the Trustee to pay interest on the Bonds when due and to pay the interest portion of the purchase price of Bonds tendered (or deemed tendered) for
purchase. The initial letter of credit to be delivered to the Trustee and any substitute letter of credit delivered to the Trustee pursuant to the Indenture are herein referred to as the “Letter of Credit.” 
 As security for the Company’s obligations under this Agreement with respect to the Letter of Credit, the Company and the Board will execute a
Mortgage and Security Agreement dated as of September 1, 2000 (the “Mortgage”) in favor of the Bank, whereby the Bank will be granted a mortgage on and security interest in the Project. 
 As additional security for the Company’s obligations under this Agreement with respect to the Letter of Credit, the Company will cause Hyco
International, Inc., a corporation organized under the laws of the State of Delaware, to execute a Corporate Guaranty Agreement dated as of September 1, 2000 in favor of the Bank.

B Drawing or C Drawing until the same has been honored in full by the Bank, and no such reimbursement shall be prepaid. 
 Section 2.03

 As security for the performance of its obligations under this Agreement, the Company and the Board shall execute the
Mortgage and deliver the same to the Bank simultaneously with the delivery of this Agreement. In addition the Company shall cause the Corporate Guarantor to execute the Credit Guaranty and deliver the same to the Bank simultaneously with the
delivery of this Agreement. 
 An “Event of Default” under the Taxable Credit Agreement (as defined therein) shall be an Event of
Default hereunder and an Event of Default hereunder shall be an “Event of Default” under the Taxable Credit Agreement. In the event of an Event of Default under either the Taxable Credit Agreement or this Agreement the Bank may enforce all
rights, remedies and powers granted the Bank therein or herein as a result of an Event of Default therein or herein. All Collateral securing the Obligations under this Agreement shall also secure the “Obligations” of the Company under the
Taxable Credit Agreement (as defined therein) and all “Collateral” under the Taxable Credit Agreement (as defined therein) shall secure all Obligations hereunder. 
 Section 2.04 Fees 
 (a) The Company
agrees to pay to the Bank an annual fee calculated at the rate of 1.25% per annum on the daily average of the Credit Amount available during the next succeeding year under the Letter of Credit. The annual fee shall be payable in advance on the
date of issuance of the Letter of Credit, for the period beginning on such date and ending on September 15, 2001, and thereafter on each September 16 for the annual period beginning on September 16 and ending on the next
September 15 (or, if sooner, the Termination Date). Fees payable for the first and the last annual payment shall be prorated based on the number of days in the period and the number of days in the period during which the Letter of Credit is
outstanding. 
 (b) The fees payable for each annual period specified in subsection (a) above shall be calculated on the assumption that
the Credit Amount available under the Letter of Credit on such due date will be available for the entire annual period for which such commission is payable. At the end of such annual period, the fee shall be recalculated based on the actual daily
average of the Credit Amount for such period and the difference, if any, shall be added to or subtracted from, as the case may be, the next quarterly payment or, if no fee is payable for the ensuing quarter, shall be paid to the party entitled
thereto within ten days of the end of such last period; provided, however, no adjustment shall be made for reductions in the Credit Amount made during the last 15 days (September 1 through September 15) of the annual period. If a Substitute
Letter of Credit is obtained by the Company, no refund of fees already paid shall be allowed for any period after the cancellation of the Letter of Credit unless the Bank notified the Company after such commission was paid that increased costs will
be payable pursuant to Section 2.05. 
  

 Page 8 

 (c) Fees payable for the first annual period with respect to the Letter of Credit shall be fully earned
and shall be nonrefundable in the event the Letter of Credit terminates during or at the end of such period. For each annual period thereafter, if the Letter of Credit expires or terminates, the Company shall be entitled to a rebate of the annual
fee paid with respect to the expired or terminated Letter of Credit based upon the number of days remaining in the annual period during which such termination occurs. 
 (d) In addition to the fees payable under subsection (a) above, the Company shall pay to the Bank such amount as shall at the time of a transfer of the Letter of Credit then be the charge which the Bank is
customarily making for transfers of similar letters of credit. Such charges shall be paid within ten days of receipt by the Company of a written statement therefor. 
 (e) For each draw on the Letter of Credit, the Company shall pay a processing fee in the amount of $75. The processing fee shall be due on the date such draw is made. 
 Section 2.05 Increased Costs 
 (a) If,
after the date of delivery of this Agreement, any change in any law or regulation or in the interpretation, administration or enforcement thereof by any court or governmental authority charged with the administration thereof or any action by any
governmental authority (whether or not constituting or resulting from such change) shall either 
 (1) impose, modify or deem
applicable any reserve, assessment, special deposit or similar requirement against letters of credit issued by the Bank, or 
 (2) impose on the Bank any other condition regarding this Agreement or the Letter of Credit, 
 and the result of any such event
shall be to increase the cost to the Bank of issuing or maintaining the Letter of Credit (which increase in cost shall be the result of the Bank’s reasonable allocation of the aggregate of such cost increases resulting from such events and
shall be calculated without giving effect to any participation granted in the Letter of Credit), then, upon demand by the Bank, the Company shall pay to the Bank from time to time, within 30 days of the Company’s receipt of the certificate
referred to in paragraph 2.05(b) below, as specified by the Bank in writing, such additional amounts which shall be sufficient to compensate the Bank for the portion of such increased costs that are allocable to the Letter of Credit. 
 (b) The Bank shall deliver to the Company a certificate as to such increased costs incurred by the Bank as a result of any event referred to in
subsection (a) of this Section, and such certificate shall be conclusive, absent manifest error, as to the amount thereof. In making the determination contemplated by such certificate, the Bank may make such reasonable, estimates, assumptions,
allocations, and the like that the Bank deems to be appropriate. 
 (c) The Bank shall make a good faith effort to notify the Company when
the Bank becomes aware of circumstances that may in the future require the imposition of increased costs pursuant to this Section, but the failure to give such notice shall not preclude the imposition of such increased costs. 
 (d) If, after the date of this Agreement, the Bank shall have determined that the adoption or implementation of any applicable law, rule or regulation
regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or
compliance by the Bank with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the 

  

 Page 9 

 
rate of return on the Bank’s capital, on this credit facility or otherwise, as a consequence of its obligations hereunder and under the Letter of Credit
to a level below that which the Bank could have achieved but for such adoption, change or compliance (taking into consideration the Bank’s policies with respect to capital adequacy) by an amount deemed by the Bank to be material, then from time
to time, promptly upon demand by the Bank, the Company hereby agrees to pay the Bank such additional amount or amounts as will compensate the Bank for such reduction. A certificate of the Bank claiming compensation under this subsection and setting
forth the additional amount or amounts to be paid to it hereunder shall be conclusive absent manifest error. In determining any such amount, the Bank may use any reasonable averaging and attribution methods. 
 (e) Upon the occurrence of any of the events described in paragraphs 2.05(a) or (d) above, the Company may, at its option, provide a substitute
letter of credit for the Letter of Credit, in which event the Bank will refund any prepaid Letter of Credit fees provided all Obligations have been paid in full. 
 Section 2.06. Place and Time of Payments 
 (a) All payments by the Company to the Bank hereunder shall
be made in lawful currency of the United States and in immediately available funds to the Bank at its address set forth in Section 6.05 hereof or at such other address within the continental United States as shall be specified by the Bank by notice
to the Company. 
 (b) All amounts payable by the Company to the Bank hereunder for which a payment date is expressly set forth herein
(including without limitation payments due pursuant to Sections 2.02 and 2.04) shall be payable without notice or written demand by the Bank. All amounts payable by the Company to the Bank hereunder for which no payment date is expressly set forth
herein shall be payable on written demand by the Bank to the Company within 15 days of receipt thereof. 
 (c) The Bank may, at its option,
send written notice to the Company of amounts payable pursuant to Sections 2.02 and 2.04, but the failure to send such notice shall not affect or excuse the Company’s obligation to make payment of the amounts required by such Sections on, the
due date specified in such Sections. 
 (d) Payments which are due on a day which is not a Business Day shall be payable on the next
succeeding Business Day, and any interest payable thereon shall be payable for such extended time at the specified rate. 
 Section 2.07
Late Payments 
 With respect to all amounts payable to the Bank by the Company pursuant to this Article (i) which are not paid on the
due date, in the case of amounts payable on a specified date, or (ii) which are not paid within 15 days of written notice to the Company, in the case of amounts payable on demand, the Company agrees to pay to the Bank on demand interest at a
variable per annum rate equal to 2% in excess of the Commercial Base Rate for each day from the specified date of payment, or the date of written demand for payment, as the case may be, to the date payment is made. 
 Section 2.08 Computation of Charges 
 The interest and charges provided for in this Agreement payable in arrears based upon annual rates shall be computed on the basis of a 365-day year, for actual days elapsed. All interest rates based upon the Commercial Base Rate shall
change when and as the Commercial Base Rate shall change, effective on the opening of business on the date of any such change, unless such change is announced after the close of regular banking hours, in which case such change shall be effective on
the following day. 
  

 Page 10

including, without limitation, the following: 
 (1) any lack of validity or enforceability of all or any of the Letter of

remedy herein conferred upon or reserved to the Bank is intended to be exclusive of any other available remedy or remedies, but each and every such remedy shall be cumulative and shall be in addition to every other remedy given under this Agreement
or now or hereafter existing at law or in equity or by statute. No delay or omission to exercise any right or power accruing upon any default shall impair any such right or power or shall be construed to be a waiver thereof but any such right or
power may be exercised from time to time and as often as may be deemed expedient. 
 Section 5.05 Agreement to Pay Attorneys’ Fees

 Section 5.06 No
Additional Waiver Implied by One Waiver 
 If any agreement contained in this Agreement should be breached by the Company and thereafter
waived by the Bank, such waiver shall be limited to the particular breach so waived and shall not be deemed to waive any other breach hereunder. 
 Section 5.07 Remedies Subject to Applicable Law 
 All rights, remedies and powers provided by this Article may be exercised
only to the extent the exercise thereof does not violate any applicable provision of law in the premises, and all the provisions of this Article are intended to be subject to all applicable mandatory provisions of law which may be controlling in the
premises and to be limited to the extent necessary so that they will not render this Agreement invalid or unenforceable. 
 Section 5.08

 2. This Letter of Credit is irrevocable and is issued to you in your capacity as Trustee (the “Trustee”) under the Trust Indenture dated as of September 1, 2000 (the “Indenture”), from The
Industrial Development Board of the City of Arab (the “IDB”) to you, pursuant to which $1,000,000 in aggregate principal amount of the IDB’s Industrial Development Revenue Bonds (Hyco Alabama Project) Series 2000 (the
“Bonds”) are being issued. Terms used but not otherwise defined herein shall have the meanings given to them in the Indenture. This Letter of Credit is issued pursuant to a Tax-Exempt Credit Agreement dated as of September 1, 2000
(the “Tax-Exempt Credit Agreement”) between the Bank and the Company. 
 3. Of the Credit Amount: (a) up to $1,000,000 (the
“Principal Portion”), which is an amount equal to the outstanding principal amount of the Bonds, may be drawn with respect to payment of the principal amount of the Bonds (i) when due at maturity, upon redemption or acceleration and
(ii) representing the principal component of the purchase price of Bonds tendered (or deemed tendered) pursuant to the Indenture; and (b) up to $11,836 (the “Interest Portion”), which is an amount equal to the maximum amount of
interest payable with respect to the Bonds for a period of 36 days, computed at the maximum assumed interest rate of 12% per annum on the basis of a 365- or 366-day year, as the case may be, for the actual number of days elapsed, may be drawn
with respect to payment of interest on the Bonds (i) when due at the maturity or upon the redemption or acceleration of the Bonds and (ii) representing the interest component of the purchase price of Bonds tendered (or deemed tendered)
pursuant to the Indenture. 
 4. Funds under this Letter of Credit are available to you against your sight draft(s), drawn on us, stating on

 Multiple demands for payment, accompanied by completed certificates in the form of Exhibits

by, or known by the Trustee to be held for the account of, the Company, the IDB or the Bank. 
 5. All documents presented to the Bank in
connection with any demand for payment under this Letter of Credit, as well as all notices and other communications to the Bank in respect hereof, shall be in writing, shall make specific references to this Letter of Credit by number, shall be to
the attention of International Department, and shall either (i) be personally delivered to the Bank at its office located at 417 North 20th Street, Birmingham, Alabama (or at any other office of the Bank designated by the Bank by written notice

 6. The Bank hereby agrees that demands for payment made under and in compliance with the terms of this Letter of Credit will
be duly honored by the Bank (from the Bank’s own funds and not directly or indirectly from funds or other assets of the Company or any affiliate of the Company) upon presentation of the certificate(s) specified in paragraph 4 hereof to the Bank
as provided in paragraph 5 hereof on or before the Stated Expiration Date (as defined in paragraph 10 hereof) or earlier termination of this Letter of Credit. 
 a) If a demand for payment is made by the Trustee hereunder at or prior to 10:00 a.m., Birmingham, Alabama time, on a Business Day (as
hereinafter defined), and if such demand for payment conforms to the terms and conditions hereof, payment shall be made of the amount specified, in immediately available funds, by 1:45 p.m., Birmingham, Alabama time, on that Business Day.

 b) If a demand for payment is made by the Trustee hereunder after 10:00 a.m. and prior to 12:00 noon, Birmingham, Alabama

 Page 31 

 
failure of the Trustee to give such notice or any discrepancies between the amount or other information set forth in such notice from the amount or other
information set forth in the certificate(s) actually presented to the Bank shall in no way relieve or otherwise change the obligation of the Bank to honor properly submitted demands for payment under this Letter of Credit. 
 7. Only the Trustee may make demands for payment under this Letter of Credit, and demands for payment under this Letter of Credit shall be presented
directly to the Bank and not negotiated. Upon payment of the amount specified in a demand for payment made hereunder, the Bank shall be fully discharged of its obligation under this Letter of Credit with respect to such demand for payment and the
Bank shall not thereafter be obligated to make any further payments under this Letter of Credit in respect of such demand for payment. By paying the Trustee an amount demanded in accordance with this Letter of Credit, the Bank makes no
representation as to the correctness of the amount demanded or of the calculations and representations of the Trustee required by this Letter of Credit. 
 8. The Credit Amount shall be automatically reduced from time to time as follows: 
 (a) Upon
a demand for payment under this Letter of Credit, (i) the Credit Amount and (ii) the Principal Portion and/or the Interest Portion, shall be reduced by an amount equal to the amount of such demand (subject, in certain instances, to
reinstatement as provided in paragraph 9 hereof); and 
 (b) Upon receipt by the Bank of the certificate of the Trustee in the
form of Exhibit D hereto, the Credit Amount shall be permanently reduced by an amount equal to the amount specified in such certificate; provided, however, that no reduction under this subparagraph shall duplicate any reduction under paragraph 8(a).

 9. The Credit Amount of this Letter of Credit shall be reinstated under the following conditions: 
 (a) Reductions under paragraph 8 hereof with respect to any demand for payment to pay interest on Bonds on interest payment dates
accompanied by a certificate in the form of Exhibit A hereto (except for interest on a Bond being paid and cancelled) shall a reinstated automatically on the same date that the Bank honors such demand for payment; and 
 (b) Reductions under paragraph 8(a) hereof with respect to any demand for payment to pay the Purchase Price of Bonds accompanied by a
certificate in the form of Exhibit C hereto shall be reinstated when the Bank is reimbursed for honoring such demand for payment and the Bank gives written notice to the Trustee, in the form of Exhibit E hereto (which notice may be delivered by
prepaid telecopier, telex, TWX or telegram), of such reinstatement, such reinstatement to be in the amount set forth in such notice. 
 10.
This Letter of Credit shall automatically terminate on the date (the “Termination Date”) which is the earliest of (i) the close of business on the date on which the Trustee returns this Letter of Credit to the Bank along with notice
that a Substitute Letter of Credit (as defined in the Indenture) has become effective; (ii) the date on which the Bank has paid a demand for payment accompanied by a certificate in the form of Exhibit B hereto where there will be no outstanding
Bonds after such payment; (iii) the later of (A) the twenty-fifth (25th) calendar day after the Bank

Indenture, due to the occurrence of a continuing Event of Default under and as defined in Section 5.01 of the 

  

 Page 32 

 
Tax-Exempt Credit Agreement or (B) in the event a temporary restraining order shall have been entered against the Bank prior to said twenty-fifth
(25th) calendar day enjoining payment hereunder, then the twenty-fifth (25th) calendar day after said temporary restraining order shall be lifted; (iv) the date on which the Trustee shall have surrendered this Letter of Credit for
cancellation; or (v) September 14, 2003 (the “Stated Termination Date”). The Stated Termination Date of this Letter of Credit will be extended automatically for successive one-year periods upon each anniversary of its initial
issuance, unless at least sixty (60) days prior to any such anniversary the Bank gives written notice, in the form of Exhibit G hereto, to the Trustee and the Company by certified mail, return receipt requested, that the Bank elects not to so
extend the Stated Expiration Date of this Letter of Credit. Upon the expiration or termination of this Letter of Credit, the Trustee shall promptly return this Letter of Credit to the Bank for cancellation. 
 11. The Trustee may transfer its rights under this Letter of Credit in their entirety (but not in part) to any transferee who, in accordance with the
provisions of the Indenture, has succeeded to the Trustee as Trustee under the Indenture (and any such transferee shall, upon the effectiveness of such transfer, be deemed to be the Trustee for purposes of this Letter of Credit) and such transferred
rights may be successively transferred. Transfer of the available demands for payment under this Letter of Credit to any such transferee shall be effected upon the presentation of this Letter of Credit to the Bank for endorsement hereon of such
transfer accompanied by a transfer letter, in the form of Exhibit H hereto, executed by the Trustee and such transferee. 
 12. This Letter
of Credit shall be subject to the Uniform Customs and Practices for Documentary Credits (1993 Revision) (“UCP”), International Chamber of Commerce, Publication No. 500, and any revisions thereof; provided, however, that Article 41 and

Bonds when due and to pay the interest portion of the purchase price of Bonds tendered (or deemed tendered) for purchase. The initial letter of credit to be delivered to the Trustee and any substitute letter of credit delivered to the Trustee
pursuant to the Indenture are herein referred to as the “Letter of Credit.” 
 As security for the Company’s obligations under
this Agreement with respect to the Letter of Credit, the Company and the Board will execute a Mortgage and Security Agreement dated as of September 1, 2000 (the “Mortgage”) in favor of the Bank, whereby the Bank will be granted a
mortgage on and security interest in the Project. 
 As additional security for the Company’s obligations under this Agreement with

and powers granted the Bank therein or herein as a result of an Event of Default therein or herein. All Collateral securing the Obligations under this Agreement shall also secure the “Obligations” of the Company under the Tax-Exempt Credit
Agreement (as defined therein) and all “Collateral” under the Tax-Exempt Credit Agreement (as defined therein) shall secure all Obligations hereunder. 
 Section 2.04 Fees 
 (a) The Company agrees to pay to the Bank an annual fee calculated at the rate of
1.25% per annum on the daily average of the Credit Amount available during the next succeeding year under the Letter of Credit. The annual fee shall be payable in advarice on the date of issuance of the Letter of Credit, for the period
beginning on such date and ending on September 15, 2001, and thereafter on each September 16 for the annual period beginning on September 16 and ending on the next September 15 (or, if sooner, the Termination Date). Fees payable
for the first and the last annual payment shall be prorated based on the number of days in the period and the number of days in the period during which the Letter of Credit is outstanding. 
 (b) The fees payable for each annual period specified in subsection (a) above shall be calculated on the assumption that the Credit Amount available
under the Letter of Credit on such due date will be available for the entire annual period for which such commission is payable. At the end of such annual period, the fee shall be recalculated based on the actual daily average of the Credit Amount
for such period and the difference, if any, shall be added to or subtracted from, as the case may be, the next quarterly payment or, if no fee is payable for the ensuing quarter, shall be paid to the party entitled thereto within ten days of the end
of such last period; provided, however, no adjustment shall be made for reductions in the Credit Amount made during the last 15 days (September 1 through September 15) of the annual period. If a Substitute Letter of Credit is obtained by the
Company, no refund of fees already paid shall be allowed, for any period after the cancellation of the Letter of Credit unless the Bank notified the Company after such commission was paid that increased costs will be payable pursuant to
Section 2.05. 
 (c) Fees payable for the first annual period with respect to the Letter of Credit shall be fully earned and shall be
nonrefundable in the event the Letter of Credit terminates during or at the end of such period. For each annual period thereafter, if the Letter of Credit expires or terminates, the Company shall be entitled to a rebate of the annual fee paid with
respect to the expired or terminated Letter of Credit based upon the number of days remaining in the annual period during which such termination occurs. 
  

 6 

 (d) In addition to the fees payable under subsection (a) above, the Company shall pay to the Bank
such amount as shall at the time of a transfer of the Letter of Credit then be the charge which the Bank is customarily making for transfers of similar letters of credit. Such charges shall be paid within ten days of receipt by the Company of a
written statement therefor. 
 (e) For each draw on the Letter of Credit, the Company shall pay a processing fee in the amount of $75. The
processing fee shall be due on the date such draw is made. 
 Section 2.05 Increased Costs 
 (a) If, after the date of delivery of this Agreement, any change in any law or regulation or in the interpretation, administration or enforcement thereof
by any court or governmental authority charged with the administration thereof or any action by any governmental authority (whether or not constituting or resulting from such change) shall either 
 (1) impose, modify or deem applicable any reserve, assessment, special deposit or similar requirement against letters of credit issued by
the Bank, or 
 (2) impose on the Bank any other condition regarding this Agreement or the Letter of Credit, and the result of
any such event shall be to increase the cost to the Bank of issuing or maintaining the Letter of Credit (which increase in cost shall be the result of the Bank’s reasonable allocation of the aggregate of such cost increases resulting from such
events and shall be calculated without giving effect to any participation granted in the Letter of Credit), then, upon demand by the Bank, the Company shall pay to the Bank from time to time, within 30 days of the Company’s receipt of the
certificate referred to in paragraph 2.05(b) below, as specified by the Bank in writing, such additional amounts which shall be sufficient to compensate the Bank for the portion of such increased costs that are allocable to the Letter of Credit.

 (b) The Bank shall deliver to the Company a certificate as to such increased costs incurred by the Bank as a result of any event referred
to in subsection (a) of this Section, and such certificate shall be conclusive, absent manifest error, as to the amount thereof. In making the determination contemplated by such certificate, the Bank may make such reasonable, estimates,
assumptions, allocations, and the like that the Bank deems to be appropriate. 
 (c) The Bank shall make a good faith effort to notify the
Company when the Bank becomes aware of circumstances that may in the future require the imposition of increased costs pursuant to this Section, but the failure to give such notice shall not preclude the imposition of such increased costs.

 (d) If, after the date of this Agreement, the Bank shall have determined that the adoption or implementation of any applicable law, rule
or regulation regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration
thereof, or compliance by the Bank with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of
return on the Bank’s capital, on this credit facility or otherwise, as a consequence of its obligations hereunder and under the Letter of Credit to a level below that which the Bank could have achieved but for such adoption, change or
compliance (taking into consideration the Bank’s policies with respect to capital adequacy) by an amount deemed by the Bank to be material, then from time to time, promptly upon demand by the Bank, the Company hereby agrees to pay the Bank such
additional amount or amounts as will compensate the Bank for such reduction. A certificate of the Bank claiming compensation under this subsection 

  

 7 

 
and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive absent manifest error. In determining any such amount, the
Bank may use any reasonable averaging and attribution methods. 
 (e) Upon the occurrence of any of the events described in paragraphs
2.05(a) or (d) above, the Company may, at its option, provide a substitute letter of credit for the Letter of Credit, in which event the Bank will refund any prepaid Letter of Credit fees provided all Obligations have been paid in full.

 Section 2.06. Place and Time of Payments 
 (a) All payments by the Company to the Bank hereunder shall be made in lawful currency of the United States and in immediately available funds to the Bank at its address set forth in Section 6.05 hereof or at such
other address within the continental United States as shall be specified by the Bank by notice to the Company.

payable by the Company to the Bank hereunder for which no payment date is expressly set forth herein shall be payable on written demand by the Bank to the Company within 15 days of receipt thereof. 
 (c) The Bank may, at its option, send written notice to the Company of amounts payable pursuant to Sections 2.02 and 2.04, but the failure to send such
notice shall not affect or excuse the Company’s obligation to make payment of the amounts required by such Sections on the due date specified in such Sections. 
 (d) Payments which are due on a day which is not a Business Day shall be payable on the next succeeding Business Day, and any interest payable thereon shall be payable for such extended time at the specified rate.

 Section 2.07 Late Payments

written notice to the Company, in the case of amounts payable on demand, the Company agrees to pay to the Bank on demand interest at a variable per annum rate equal to 2% in excess of the Commercial Base Rate for each day from the specified date of
payment, or the date of written demand for payment, as the case may be, to the date payment is made. 
 Section 2.08 Computation of
Charges 
 The interest and charges provided for in this Agreement payable in arrears based upon annual rates shall be computed on the basis
of a 365-day year, for actual days elapsed. All interest rates based upon the Commercial Base Rate shall change when and as the Commercial Base Rate shall change, effective on the opening of business on the date of any such change, unless such

demand for payment for interest or principal in respect of the Bonds, but failure of the Trustee to give such notice or any discrepancies between the amount
