 NORTHWEST PIPE COMPANY 
 200 SW Market Street, Suite 1800 
 Portland, Oregon 97201 
  
 As of February 25, 2004 
  
 Prudential Investment Management, Inc. 
 The Prudential Insurance Company of America 
 Each Prudential Affiliate (as
hereinafter defined) 
 which becomes bound by certain provisions 
 of this Agreement as hereinafter provided 
 c/o Prudential
Capital Group 
 Four Embarcadero Center, Suite 2700 
 San
Francisco, California 94111 
  
 Ladies and Gentlemen: 
  
 The undersigned, Northwest Pipe Company, an Oregon corporation (the
“Company”), hereby agrees with you as follows: 
  

	1.	AUTHORIZATION OF ISSUE OF NOTES 

  

	 	1A.	Authorization of Issue of Series A Notes. 

  
 The Company has authorized the issue and sale of its Series A Senior Secured Notes (the “Series A Notes”) in the aggregate principal
amount of $15,000,000, to be dated as of the date hereof, to mature February 25, 2014, to bear interest on the unpaid balance thereof from the date thereof until the principal thereof shall have become due and payable at the rate of 8.75% per annum
and on any overdue payment of principal, interest or Yield-Maintenance Amount at the rate specified in the Series A Notes, and to be substantially in the form of Exhibit A-1 attached hereto. 
  
 The terms “Series A Note” and “Series A
Notes” as used herein shall include each Series A Note delivered pursuant to any provision of this Agreement and each Series A Note delivered in substitution or exchange for any such Series A Note pursuant to any such provision. Certain
capitalized terms used in this Agreement are defined in paragraph 10; references to a paragraph are, unless otherwise specified, to one of the paragraphs of this Agreement and references to an “Exhibit” or
“Schedule” are, unless otherwise specified, to one of the exhibits or schedules attached to this Agreement. 
  

	 	1B.	Authorization of Issue of Shelf Notes. 

  
 The Company will authorize the issue of additional senior secured promissory notes (the “Shelf Notes”) in an aggregate principal amount
of up to $25,000,000, to be dated the date of issue thereof, to mature, in the case of each Shelf Note so issued, no more than 10 years after the date of original issuance thereof, to have an average life, in the case of each Shelf Note so issued,
of no more than 7 years, to bear interest on the unpaid balance thereof from the date thereof at the rate per annum, and to have such other particular terms, as shall be set forth, in the case of each Shelf Note so issued, in the Confirmation of
Acceptance with respect to such Shelf Note delivered pursuant to paragraph 2B(5), and to be substantially in the form of Exhibit A-2 attached hereto. 
  
 The terms “Shelf Note” and “Shelf Notes” as used herein shall include each Shelf Note delivered pursuant to any
provision of this Agreement and each Shelf Note delivered in substitution or exchange for any such Shelf Note pursuant to any such provision. The terms “Note” and “Notes” as used herein shall include each Series A
Note and each Shelf Note delivered pursuant to any provision of this Agreement and each Note delivered in substitution or exchange for any such Note pursuant to any such provision. Notes which have (i) the same final maturity, (ii) the same
principal prepayment dates, (iii) the same principal prepayment amounts (as a percentage of the original principal amount of each Note), (iv) the same interest rate, (v) the same interest payment periods and (vi) the same date of issuance (which, in
the case of a Note issued in exchange for another Note, shall be deemed for these purposes the date on which such Note’s ultimate predecessor Note was issued), are herein called a “Series” of Notes. 
  

	2.	PURCHASE AND SALE OF NOTES 

  

	 	2A.	Purchase and Sale of Series A Notes. 

  
 The Company hereby agrees to sell to Prudential and, subject to the terms and conditions herein set forth, Prudential hereby agrees to purchase from the
Company $15,000,000 in principal amount of Series A Notes at 100% of such principal amount. On February 25, 2004 (herein called the “Series A Closing Day”), the Company will deliver to Prudential at the offices of Bingham McCutchen
LLP, Three Embarcadero Center, San Francisco, California, one or more Series A Notes registered in its name, evidencing the aggregate principal amount of Series A Notes to be purchased by Prudential and in the denomination or denominations specified
in the Purchaser Schedule attached hereto (the “Purchaser Schedule”), against payment of the purchase price thereof by wire transfer of immediately available funds as set forth in the Series A Notes Funding Instruction Letter
attached hereto as Exhibit B. 
  

	 	2B.	Purchase and Sale of Shelf Notes. 

  

	 	2B(1).	Facility. 

  
 Subject to paragraph 2B(2), PIM is willing to consider, in its sole discretion and within limits which may be authorized for purchase by
PIM and Prudential Affiliates from time to time, the purchase of Shelf Notes pursuant to this Agreement. The 

  

 2 

 
willingness of PIM to consider such purchase of Shelf Notes is herein called the “Facility.” At any time, (i) $25,000,000, minus (ii)
the aggregate principal amount of Shelf Notes purchased and sold pursuant to this Agreement prior to such time, minus (iii) the aggregate principal amount of Accepted Shelf Notes which have not yet been purchased and sold hereunder prior to
such time is herein called the “Available Facility Amount” at such time. NOTWITHSTANDING THE WILLINGNESS OF PIM TO CONSIDER PURCHASES OF SHELF NOTES, THIS AGREEMENT IS ENTERED INTO ON THE EXPRESS UNDERSTANDING THAT NEITHER PIM
NOR ANY PRUDENTIAL AFFILIATE SHALL BE OBLIGATED TO MAKE OR ACCEPT OFFERS TO PURCHASE SHELF NOTES, OR TO QUOTE RATES, SPREADS OR OTHER TERMS WITH RESPECT TO SPECIFIC PURCHASES OF SHELF NOTES, AND THE FACILITY SHALL IN NO WAY BE CONSTRUED AS A
COMMITMENT BY PIM OR ANY PRUDENTIAL AFFILIATE. 
  

	 	2B(2).	Issuance Period. 

  
 Shelf Notes may be issued and sold pursuant to this Agreement until the earlier of (i) the third anniversary of the date of this Agreement
(or if any such anniversary is not a Business Day, the Business Day next preceding such anniversary) and (ii) the thirtieth day after PIM shall have given to the Company, or the Company shall have given to PIM, written notice stating that it elects
to terminate the issuance and sale of Shelf Notes pursuant to this Agreement (or if such thirtieth day is not a Business Day, the Business Day next preceding such thirtieth day). The period during which Shelf Notes may be issued and sold pursuant to
this Agreement is herein called the “Issuance Period.” 
  

	 	2B(3).	Request for Purchase. 

  
 The Company may from time to time during the Issuance Period make requests for purchases of Shelf Notes (each such request being herein
called a “Request for Purchase”). Each Request for Purchase shall be made to PIM by facsimile or overnight delivery service, and shall (i) specify the aggregate principal amount of Shelf Notes covered thereby, which shall not be
less than $5,000,000 and not be greater than the Available Facility Amount at the time such Request for Purchase is made, (ii) specify the principal amounts, final maturities (which shall be no more than 10 years from the date of issuance),
principal prepayment dates and amounts (which shall result in an average life of no more than 7 years), and the Designated Spread of the Shelf Notes covered thereby, (iii) specify the use of proceeds of such Shelf Notes, (iv) specify the proposed
day for the closing of the purchase and sale of such Shelf Notes, which shall be a Business Day during the Issuance Period not less than 7 days and not more than 20 days after the making of such Request for Purchase, (v) specify the number of the
account and the name and address of the depository institution to which the purchase prices of such Shelf Notes are to be transferred on the Closing Day for such purchase and sale, (vi) certify that the representations and warranties contained in
paragraph 8 are true on and as of the date of such Request for Purchase and that there exists on the date of such Request for Purchase no Event of Default or Default and (vii) be substantially in the form of Exhibit C attached 

  

 3 

 
hereto. Each Request for Purchase shall be in writing and shall be deemed made when received by PIM. 
  

	 	2B(4).	Rate Quotes. 

  
 Not later than five Business Days after the Company shall have given PIM a Request for Purchase pursuant to paragraph 2B(3), PIM may, but
shall be under no obligation to, provide to the Company by telephone interest rate quotes for the several principal amounts, maturities and principal prepayment schedules of Shelf Notes specified in such Request for Purchase. Each such quote shall
represent the interest rate per annum payable on the outstanding principal balance of such Shelf Notes, until such balance shall have become due and payable, at which PIM or a Prudential Affiliate would be willing to purchase such Shelf Notes at
100% of the principal amount thereof. 
  

	 	2B(5).	Acceptance. 

  
 Within 2 minutes after PIM shall have provided any interest rate quotes pursuant to paragraph 2B(4), or such shorter period as PIM may
specify to the Company (such period herein called the “Acceptance Window”), the Company may, subject to paragraph 2B(6), elect to accept such interest rate quotes as to not less than $5,000,000 aggregate principal amount of the
Shelf Notes specified in the related Request for Purchase. Such election shall be made by an Authorized Officer of the Company notifying PIM by telephone or facsimile within the Acceptance Window (but not earlier than 9:30 a.m. or later than 1:30
p.m. (or such later time as PIM may agree), New York City local time) that the Company elects to accept such interest rate quotes, specifying the Shelf Notes (each such Shelf Note being herein called an “Accepted Shelf Note”) as to
which such acceptance (herein called an “Acceptance”) relates. The day the Company notifies PIM of an Acceptance with respect to any Accepted Shelf Notes is herein called the “Acceptance Day” for such Accepted Shelf
Notes. Any interest rate quotes as to which PIM does not receive an Acceptance within the Acceptance Window shall expire, and no purchase or sale of Shelf Notes hereunder shall be made based on such expired interest rate quotes. Subject to
paragraphs 2B(2) and 2B(6) and the other terms and conditions hereof, the Company agrees to sell to PIM or a Prudential Affiliate, and PIM agrees to purchase, or to cause the purchase by a Prudential Affiliate of, the Accepted Shelf Notes at 100% of
the principal amount of such Notes. As soon as practicable following the Acceptance Day, the Company, PIM and each Prudential Affiliate which is to purchase any such Accepted Shelf Notes will execute a confirmation of such Acceptance substantially
in the form of Exhibit D attached hereto (herein called a “Confirmation of Acceptance”). If the Company should fail to execute and return to PIM by facsimile a Confirmation of Acceptance with respect to any Accepted Shelf
Notes within two Business Days following receipt thereof from PIM by facsimile, PIM may at its election at any time prior to its receipt thereof cancel the closing with respect to such Accepted Shelf Notes by so notifying the Company in writing by
facsimile. 
  

 4 

	 	2B(6).	Market Disruption. 

  
 Notwithstanding the provisions of paragraph 2B(5), if PIM shall have provided interest rate quotes pursuant to paragraph 2B(4) and
thereafter, prior to the time an Acceptance with respect to such quotes shall have been notified to PIM in accordance with paragraph 2B(5), the domestic market for U.S. Treasury securities or derivatives shall have closed or there shall have
occurred a general suspension, material limitation, or significant disruption of trading in securities generally on the New York Stock Exchange or in the domestic market for U.S. Treasury securities or derivatives, then such interest rate quotes
shall expire, and no purchase or sale of Shelf Notes hereunder shall be made based on such expired interest rate quotes. If the Company thereafter notifies PIM of the Acceptance of any such interest rate quotes, such Acceptance shall be ineffective
for all purposes of this Agreement, and PIM promptly shall notify the Company that the provisions of this paragraph 2B(6) are applicable with respect to such Acceptance. 
  

	 	2B(7).	Facility Closings. 

  
 Not later than 1:30 p.m. (New York City local time) on the Closing Day for any Accepted Shelf Notes, the Company will deliver to each
Purchaser listed in the Confirmation of Acceptance relating thereto at the offices of Prudential Capital Group, Four Embarcadero Center, Suite 2700, San Francisco, California 94111 (or such other address as PIM may specify in writing), the Accepted
Shelf Notes to be purchased by such Purchaser in the form of one or more Notes in authorized denominations as such Purchaser may request for each Series of Accepted Shelf Notes to be purchased on such Closing Day, dated the Closing Day and
registered in such Purchaser’s name (or in the name of its nominee), against payment of the purchase price thereof by transfer of immediately available funds for credit to the account(s) specified in the Request for Purchase of such Shelf
Notes. If the Company fails to tender to any Purchaser the Accepted Shelf Notes to be purchased by such Purchaser on the scheduled Closing Day for such Accepted Shelf Notes as provided above in this paragraph 2B(7), or any of the conditions
specified in paragraph 3 shall not have been fulfilled by the time required on such scheduled Closing Day, the Company shall, prior to 2:00 p.m., New York City local time, on such scheduled Closing Day notify PIM (which notification shall be deemed
received by each Purchaser) in writing by facsimile whether (i) such closing is to be rescheduled (such rescheduled date to be a Business Day during the Issuance Period not less than one Business Day and not more than 10 Business Days after such
scheduled Closing Day (the “Rescheduled Closing Day”)) and certify to PIM (which certification shall be for the benefit of each Purchaser) that the Company reasonably believes that it will be able to comply with the conditions set

	 	2B(8).	Fees. 

  
 2B(8)(i). Structuring Fee. 
  
 In consideration for the time, effort and expense involved in the preparation, negotiation and execution of this Agreement, the Company

2B(8)(ii). Draw Fees. 
  
 The Company will pay to PIM in immediately available funds a fee (herein called a “Draw Fee”) on each Closing Day (other
than the Series A Closing Day) in an amount equal to 0.20% of the aggregate principal amount of Notes sold on such Closing Day. 
  
 2B(8)(iii). Delayed Delivery Fee. 
  
 If the closing of the purchase and sale of any Accepted Shelf Note is delayed for any reason beyond the original Closing Day for such
Accepted Shelf Note, the Company will pay to PIM on (x) the Cancellation Date or actual closing date of such purchase and sale or (y) if earlier, the next Business Day following 90 days after the Acceptance Day for such Accepted Shelf Note, a fee

 where “BEY” means Bond Equivalent Yield, i.e., the bond equivalent yield per annum of such Accepted Shelf Note; “MMY” means Money Market Yield, i.e., the yield per annum on a commercial paper
investment of the highest quality selected by PIM on the date PIM receives notice of the delay in the closing for such Accepted Shelf Note having a maturity date or dates the same as, or closest to, the Rescheduled Closing Day or Rescheduled Closing
Days (a new alternative investment being selected by PIM each time such closing is delayed); “DTS” means Days to Settlement, i.e., the number of actual days elapsed from and including the original Closing Day with respect to

Accepted Shelf Note) to but excluding the date of such payment; and “PA” means Principal Amount, i.e., the principal amount of the Accepted Shelf Note for which such calculation is being made. In no case shall the Delayed
Delivery Fee be less than zero. Nothing contained herein shall obligate any Purchaser to purchase any Accepted Shelf Note on any day other than

the Closing Day for such Accepted Shelf Note, as the same may be rescheduled from time to time in compliance with paragraph 2B(7). 
  
 2B(8)(iv). Cancellation Fee.

that the closing of the purchase and sale of such Accepted Shelf Note is to be canceled, or if the closing of the purchase and sale of such Accepted Shelf Note is not consummated on or prior to the last day of the Issuance Period (the date of any
such notification, or the last day of the Issuance Period, as the case may be, being herein called the “Cancellation Date”), the Company will pay the Purchasers in immediately available funds an amount (the “Cancellation
Fee”) calculated as follows: 
  
 PI X PA 
  
 where “PI” means Price Increase, i.e., the quotient
(expressed in decimals) obtained by dividing (a) the excess of the ask price (as determined by PIM) of the Hedge Treasury Note(s) on the Cancellation Date over the bid price (as determined by PIM) of the Hedge Treasury Notes(s) on the Acceptance Day
for such Accepted Shelf Note by (b) such bid price; and “PA” has the meaning ascribed to it in paragraph 2B(8)(iii). The foregoing bid and ask prices shall be as reported by such publicly available source of such market data as is
then customarily used by PIM. Each price shall be based on a U.S. Treasury security having a par value of $100.00 and shall be rounded to the second decimal place. In no case shall the Cancellation Fee be less than zero.

	8.	REPRESENTATIONS, COVENANTS AND WARRANTIES. 

  
 The Company represents, covenants and warrants as follows: 
  

	 	8A.	Organization. 

  
 The Company is a corporation duly organized and existing in good standing under the laws of its state of incorporation, each other Credit Party is duly
organized and existing in good standing under the laws of the jurisdiction in which it is formed, and each Credit Party has the power to own its respective property and to carry on its respective business as now being conducted. 
  

	 	8B.	Financial Statements. 

  
 The Company has furnished each Purchaser of the Series A Notes and any Accepted Shelf Notes with the following financial statements: (i) consolidated
balance sheets of the Company and its Subsidiaries as at December 31st in each of the three fiscal years of the Company most recently completed prior to the date as of which this representation is made or repeated to such Purchaser (other than
fiscal years completed within 105 days prior to such date for which audited financial statements have not been released) and consolidating (by division and product line) and consolidated statements of income and cash flows and a consolidated
statement of shareholders’ equity of the Company and its Subsidiaries for each such year, all reported on by PricewaterhouseCoopers LLP and (ii) consolidated balance sheets of the Company and its Subsidiaries as at the end of the quarterly
period (if any) most recently completed prior to such date and after the end of such fiscal year (other than quarterly periods completed within 60 days prior to such date for which financial statements have not been released) and the comparable
quarterly period in the preceding fiscal year and consolidating (by division and product line) consolidated statements of income and cash flows and a consolidated statement of shareholders’ equity for the periods from the beginning of the
fiscal years in which such quarterly periods are included to the end of such quarterly periods, prepared by the Company. Such financial statements (including any related schedules and/or notes) are true and correct in all material respects (subject,
as to interim statements, to changes resulting from audits and year-end adjustments and the absence of all required footnotes), have been prepared in accordance with GAAP consistently followed throughout the periods involved and show all
liabilities, direct and contingent, of the Company and its Subsidiaries required to be shown in accordance with such principles. The balance sheets fairly present the consolidated condition of the Company and its Subsidiaries as at the dates
thereof, and the statements of income, stockholders’ equity and cash flows fairly present the results of the operations of the Company and its Subsidiaries and their cash flows for the periods indicated. There has been no material adverse
change in the business, property or assets, financial condition or operations of the Company or its Subsidiaries taken as a whole since (a) with respect to the closing of the Series A Notes, September 30, 2003, and (b) with respect to the closing of
any Shelf Notes, the end of the most recent fiscal year for which such audited financial statements have been furnished. 
  

 32 

	 	8C.	Actions Pending. 

  
 There is no action, suit, investigation or proceeding pending or, to the knowledge of the Company, threatened against any of the Credit Parties or any
Subsidiaries or any properties or rights of such Persons, by or before any court, arbitrator or administrative or governmental body which would reasonably be expected to have a Material Adverse Effect. 
  

	 	8D.	Outstanding Debt. 

  
 The Credit Parties do not have outstanding any Debt except as permitted by paragraphs 6A(1) and 6D. There exists no default under the provisions of any
instrument evidencing such indebtedness or of any agreement relating thereto. 
  

	 	8E.	Title to Properties. 

  
 Each of the Credit Parties and Subsidiaries has good and marketable title to its respective real properties (other than properties which it leases) and
good and merchantable title to all of its other respective properties and assets (other than properties which it leases), including the properties and assets reflected in the most recent audited balance sheet referred to in paragraph 8B (other than
properties and assets disposed of in the ordinary course of business), subject to no Lien of any kind except Liens permitted by paragraph 6E. All leases necessary in any material respect for the conduct of the respective businesses of the Credit
Parties and Subsidiaries are valid and subsisting and are in full force and effect. 
  

	 	8F.	Taxes. 

  
 Each of the Credit Parties has filed all federal, state and other income tax returns which, to the best knowledge of the officers such Credit Parties are
required to be filed, and each has paid all taxes as shown on such returns and on all assessments received by it to the extent that such taxes have become due, except such taxes as are being contested in good faith by appropriate proceedings for
which adequate reserves have been established in accordance with GAAP. The Company has no knowledge of any pending assessments or adjustments of its income tax payable with respect to any year that could, with reasonable likelihood, have a Material
Adverse Effect. 
  

	 	8G.	Conflicting Agreements and Other Matters. 

  
 Neither the execution and delivery of this Agreement, the Notes or any other Transaction Document, nor the offering, issuance and sale of the Notes, nor
the fulfillment by the Credit Parties of, nor the compliance by the Credit Parties with, the terms and provisions hereof and of the Notes will conflict with, or result in a breach of the terms, conditions or provisions of, or constitute a default
under, or result in any violation of, or result in the creation of any Lien upon any of the properties or assets of any Credit Party or Subsidiary pursuant to the charter or by-laws of any such Person, any award of any arbitrator or any agreement
(including any agreement 

  

 33 

 
with stockholders of such Persons), instrument, order, judgment, decree, statute, law, rule or regulation to which such Person is subject. Neither the Credit
Parties nor any Subsidiary is a party to, or otherwise subject to any provision contained in, any instrument evidencing indebtedness of such Person, any agreement relating thereto or any other contract or agreement (including its charter) which
limits the amount of, or otherwise imposes restrictions on the incurring of, indebtedness of such Person of the type to be evidenced by the Notes or created by the Multiparty Guaranty except as set forth in the agreements listed in Schedule
8G attached hereto (as such Schedule 8G may have been modified from time to time by written supplements thereto delivered by the Company to PIM). 
  

	 	8H.	Offering of Notes. 

  
 Neither the Company nor any agent acting on its behalf has, directly or indirectly, offered the Notes or any similar security of the Company for sale to,
or solicited any offers to buy the Notes or any similar security of the Company from, or otherwise approached or negotiated with respect thereto with, any Person other than not more than 10 Institutional Investors, and neither the Company nor any
agent acting on its behalf has taken or will take any action which would subject the issuance, offer or sale of the Notes to the provisions of Section 5 of the Securities Act or to the provisions of any securities or Blue Sky law of any applicable
jurisdiction. 
  

	 	8I.	Use of Proceeds. 

  
 The proceeds of the Series A Notes will be used to (i) refinance a portion of certain existing Debt of the Company and (ii) provide working capital and
funds for other corporate purposes. None of the proceeds of the sale of any Notes will be used, directly or indirectly, for the purpose, whether immediate, incidental or ultimate, of purchasing or carrying any “margin stock” as defined in
Regulation U of the Board of Governors of the Federal Reserve System (herein called “margin stock”) or for the purpose of maintaining, reducing or retiring any indebtedness which was originally incurred to purchase or carry any stock that
is then currently a margin stock or for any other purpose which would constitute the purchase of such Notes a “purpose credit” within the meaning of such Regulation U. Neither the Company nor any agent acting on its behalf has taken or
will take any action which might cause this Agreement or the Notes to violate Regulation U, Regulation T or any other regulation of the Board of Governors of the Federal Reserve System or to violate the Exchange Act, in each case as in effect now or
as the same may hereafter be in effect. 
  

	 	8J.	ERISA. 

  
 No accumulated funding deficiency (as defined in section 302 of ERISA and section 412 of the Code), whether or not waived, exists with respect to any Plan
(other than a Multiemployer Plan). No liability to the Pension Benefit Guaranty Corporation has been or is expected by the Credit Parties, any Subsidiary or any ERISA Affiliate to be incurred with respect to any Plan (other than a Multiemployer
Plan) by the Credit Parties, any Subsidiary or any ERISA Affiliate which is or would be materially adverse to the business, property or assets, condition (financial or otherwise) or operations of the Credit Parties and Subsidiaries taken as a whole.
Neither the 

  

 34 

 
Credit Parties, any Subsidiary nor any ERISA Affiliate has incurred or presently expects to incur any withdrawal liability under Title IV of ERISA with
respect to any Multiemployer which is or would be materially adverse to the business, property or assets, condition (financial or otherwise) or operations of the Credit Parties and Subsidiaries taken as a whole. The execution and delivery of this
Agreement and the issuance and sale of the Notes will be exempt from or will not involve any transaction which is subject to the prohibitions of section 406 of ERISA and will not involve any transaction in connection with which a penalty could be
imposed under section 502(i) of ERISA or a tax could be imposed pursuant to section 4975 of the Code. The representation by the Company in the next preceding sentence is made in reliance upon and subject to the accuracy of the representation of each
Purchaser in paragraph 9B as to the source of funds to be used by it to purchase any Notes. 
  

	 	8K.	Governmental Consent. 

  
 Neither the nature of the Credit Parties or any Subsidiary, nor any of their respective businesses or properties, nor any relationship between any of the
Credit Parties or any Subsidiary and any other Person, nor any circumstance in connection with the offering, issuance, sale or delivery of the Notes or the use of the proceeds thereof is such as to require any authorization, consent, approval,
exemption or any action by or notice to or filing with any court or administrative or governmental body (other than routine filings after the Closing Day for any Notes with the Securities and Exchange Commission and/or state Blue Sky authorities and
the filing of UCC financing statements or amendments) in connection with the execution and delivery of this Agreement and the other Transaction Documents, the offering, issuance, sale or delivery of the Notes or fulfillment of or compliance with the
terms and provisions hereof or of any other Transaction Document. 
  

	 	8L.	Compliance With Laws. 

  
 The Company and its Subsidiaries and all of their respective properties and facilities have complied at all times and in all respects with all foreign,
federal, state, local and regional statutes, laws, ordinances and judicial or administrative orders, judgments, rulings and regulations, including all Environmental Laws and the Fair Labor Standards Act except, in any such case, where failure
to comply would not, with reasonable likelihood, have a Material Adverse Effect. 
  

	 	8M.	Disclosure. 

  
 Neither this Agreement or any of the other Transaction Documents nor any other document, certificate or statement furnished to any Purchaser by or on
behalf of any Credit Party or any Subsidiary in connection herewith or in connection with the issuance of the Notes contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements
contained herein and therein not misleading. There is no fact known to any Credit Party that could reasonably be expected to have a Material Adverse Effect that has not been set forth herein or in the other documents, certificates and other writings
delivered to any Purchaser by or on behalf of any Credit Party specifically for use in connection with the transactions contemplated hereby. Any financial projections delivered by the Company 

  

 35 

 
to PIM are reasonable on the date delivered based upon the assumptions stated therein and the best information available to the officers of the Company as of
the date delivered. 
  

	 	8N.	Hostile Tender Offers. 

  
 None of the proceeds of the sale of any Notes will be used to finance a Hostile Tender Offer. 
  

	 	8O.	Regulatory Status. 

  
 Neither any of the Credit Parties nor any Subsidiary (i) is an “investment company” or a company “controlled” by an “investment
company” within the meaning of the Investment Company Act of 1940, as amended, (ii) is a “holding company” or a “subsidiary company” or an “affiliate” of a “holding company” or a “subsidiary
company” of a “holding company” within the meaning of the Public Utility Act of 1935, as amended, (iii) is a “public utility” within the meaning of the Federal Power Act, as amended, or (iv) is a Person described by section
1 of the Anti-Terrorism Order or engages in any dealings or transactions, or is otherwise associated, with any such Persons or entities. 
  

	 	8P.	Absence of Financing Statements. 

  
 Except with respect to Liens permitted by paragraph 6E hereof, there is no financing statement, security agreement, chattel mortgage, real estate mortgage
or other document filed or recorded with any filing records, registry or other public office, that purports to cover, affect or give notice of any present or possible future Lien on, or security interest in, any assets or property of the Credit
Parties or any rights relating thereto. 
  

	 	8Q.	Collateral Documents. 

  
 The provisions of the Collateral Documents are effective to create in favor of the Collateral Agent, a legal, valid and enforceable first priority
security interest in all right, title and interest of each Credit Party in the collateral described therein, prior and superior to all other Liens and interests, other than Liens permitted in paragraph 6E.

	 	9A.	Nature of Purchase. 

  
 Such Purchaser is purchasing the Notes to be purchased by it hereunder for its own account or for one or more separate accounts or investment funds

investment fund, within the meaning of the PTE 91-38 and, except as disclosed by such Purchaser to the Company in writing pursuant to this clause (iii), no employee benefit plan or group of plans maintained by the same employer or employee
organization beneficially owns more than 10% of all assets allocated to such pooled separate account or collective investment fund; or

of such QPAM and (b) the names of all employee benefit plans whose assets are included in such investment fund have been disclosed to the Company in writing pursuant to this clause (iv); or 
  
 (v) the Source constitutes assets of a
“plan(s)” (within the meaning of Section IV of PTE 96-23 (the “INHAM Exemption”)) managed by an “in-house asset manager” or “INHAM” (within the meaning of Part IV of the INHAM
exemption), the conditions of Part I(a), (g) and (h) of the INHAM Exemption are satisfied, neither the INHAM nor a person controlling or controlled by the INHAM (applying the definition of “control” in Section IV(h) of the INHAM Exemption)

 (vi) the Source is a governmental plan; or

benefit plans, or a separate account or trust fund comprised of one or more employee benefit plans, each of which has been identified to the Company in writing pursuant to this clause (vii); or

	 	11D.	Form, Registration, Transfer and Exchange of Notes; Lost Notes. 

  
 The Notes are issuable as registered notes without coupons in denominations of at least $1,000,000, except as may be necessary to reflect any principal
amount not evenly divisible by $1,000,000. The Company shall keep at its principal office a register in which the Company shall provide for the registration of Notes and of transfers of Notes. Upon surrender for registration of transfer of any Note
at the principal office of the Company, the Company shall, at its expense, execute and deliver one or more new Notes of like tenor and of a like aggregate principal amount, registered in the name of such transferee or transferees. At the option of
the holder of any Note, such Note may be exchanged for other Notes of like tenor and of any authorized denominations, of a like aggregate principal amount, upon surrender of the Note to be exchanged at the principal office of the Company. Whenever
any Notes are so surrendered for exchange, the Company shall, at its expense, execute and deliver the Notes which the holder making the exchange is entitled to receive. Each installment of principal payable on each installment date upon each new
Note issued upon any such transfer or exchange shall be in the 

  

 53 

 
same proportion to the unpaid principal amount of such new Note as the installment of principal payable on such date on the Note surrendered for registration
of transfer or exchange bore to the unpaid principal amount of such Note. No reference need be made in any such new Note to any installment or installments of principal previously due and paid upon the Note surrendered for registration of transfer
or exchange. Every Note surrendered for registration of transfer or exchange shall be duly endorsed, or be accompanied by a written instrument of transfer duly executed, by the holder of such Note or such holder’s attorney duly authorized in
writing. Any Note or Notes issued in exchange for any Note or upon transfer thereof shall carry the rights to unpaid interest and interest to accrue which were carried by the Note so exchanged or transferred, so that neither gain nor loss of
interest shall result from any such transfer or exchange. Upon receipt of written notice from the holder of any Note of the loss, theft, destruction or mutilation of such Note and, in the case of any such loss, theft or destruction, upon receipt of
such holder’s unsecured indemnity agreement, or in the case of any such mutilation upon surrender and cancellation of such Note, the Company will make and deliver a new Note, of like tenor, in lieu of the lost, stolen, destroyed or mutilated
Note. 
  

	 	11E.	Persons Deemed Owners; Participations. 

  
 Prior to due presentment for registration of transfer, the Company may treat the Person in whose name any Note is registered as the owner and holder of
such Note for the purpose of receiving payment of principal of and interest on, and any Yield-Maintenance Amount payable with respect to, such Note and for all other purposes whatsoever, whether or not such Note shall be overdue, and the Company
shall not be affected by notice to the contrary. Subject to the preceding sentence, the holder of any Note may from time to time grant participations in all or any part of such Note to any Person on such terms and conditions as may be determined by
such holder in its sole and absolute discretion. 
  

	 	11F.	Survival of Representations and Warranties; Entire Agreement. 

  
 All representations and warranties contained herein or made in writing by or on behalf of any Credit Party in connection herewith shall survive the
execution and delivery of this Agreement, the Notes and the other Transaction Documents, the transfer by any Purchaser of any Note or portion thereof or interest therein and the payment of any Note, and may be relied upon by any Transferee,
regardless of any investigation made at any time by or on behalf of any Purchaser or any Transferee. Subject to the preceding sentence, this Agreement, the Notes and the other Transaction Documents embody the entire agreement and understanding
between the parties hereto with respect to the subject matter hereof and supersede all prior agreements and understandings relating to such subject matter. 
  

	 	11G.	Successors and Assigns. 

  
 All covenants and other agreements in this Agreement contained by or on behalf of any of the parties hereto shall bind and inure to the benefit of the
respective successors and assigns of the parties hereto (including, without limitation, any Transferee) whether so expressed or not; 

  

 54 

 
provided, however, that the Company may not assign its rights or obligations hereunder to any Person. 
  

	 	11H.	Independence of Covenants. 

  
 All covenants hereunder shall be given independent effect so that if a particular action or condition is prohibited by any one of such covenants, the fact
that it would be permitted by an exception to, or otherwise be in compliance within the limitations of, another covenant shall not avoid the occurrence of a Default or Event of Default if such action is taken or such condition exists. 
  

	 	11I.	Notices. 

  
 All written communications provided for hereunder (other than communications provided for under paragraph 2) shall be sent by first class mail or
nationwide overnight delivery service (with charges prepaid) and (i) if to any Purchaser, addressed as specified for such communications in the Purchaser Schedule attached hereto (in the case of the Series A Notes) or the Purchaser Schedule attached
to the applicable Confirmation of Acceptance (in the case of any Shelf Notes) or at such other address as any such Purchaser shall have specified to the Company in writing, (ii) if to any other holder of any Note, addressed to it at such address as
it shall have specified in writing to the Company or, if any such holder shall not have so specified an address, then addressed to such holder in care of the last holder of such Note which shall have so specified an address to the Company and (iii)

Oregon 97201, Fax No. 503-226-0079. Any communication pursuant to paragraph 2 shall be made by the method specified for such communication in paragraph 2, and shall be effective to create any rights or obligations under this Agreement only if, in
the case of a telephone communication, an Authorized Officer of the party conveying the information and of the party receiving the information are parties to the telephone call, and in the case of a facsimile communication, the communication is
signed by an Authorized Officer of the party conveying the information, addressed to the attention of an Authorized Officer of the party receiving the information, and in fact received at the facsimile terminal the number of which is listed for the
party receiving the communication in the Purchaser Schedule or at such other facsimile terminal as the party receiving the information shall have specified in writing to the party sending such information. 
  

	 	11J.	Payments Due on Non-Business Days. 

  
 Anything in this Agreement, the Notes or the other Transaction Documents to the contrary notwithstanding, any payment of principal of or interest on, or
Yield-Maintenance Amount payable with respect to, any Note that is due on a date other than a Business Day shall be made on the next succeeding Business Day. If the date for any payment is extended to the next succeeding Business Day by reason of
the preceding sentence, the period of such extension shall not be included in the computation of the interest payable on such Business Day. 
  

 55 

	 	11K.	Severability. 

  
 Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

  

	 	11L.	Descriptive Headings. 

  
 The descriptive headings of the several paragraphs of this Agreement are inserted for convenience only and do not constitute a part of this Agreement.

  

	 	11M.	Satisfaction Requirement. 

  
 If any agreement, certificate or other writing, or any action taken or to be taken, is by the terms of this Agreement required to be satisfactory to any
Purchaser, to any holder of Notes or to the Required Holder(s), the determination of such satisfaction shall be made by such Purchaser, such holder or the Required Holder(s), as the case may be, in the sole and exclusive judgment (exercised in good
faith) of the Person or Persons making such determination. 
  

	 	11N.	Governing Law. 

  
 THIS AGREEMENT SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, AND THE RIGHTS OF THE PARTIES SHALL BE GOVERNED BY, THE INTERNAL LAW OF THE STATE OF
NEW YORK, EXCLUDING CHOICE-OF-LAW PRINCIPLES OF THE LAW OF SUCH STATE THAT WOULD REQUIRE THE APPLICATION OF THE LAWS OF A JURISDICTION OTHER THAN SUCH STATE. 
  

	 	11O.	Severalty of Obligations. 

  
 The sales of Notes to the Purchasers are to be several sales, and the obligations of PIM and the Purchasers under this Agreement are several obligations.
No failure by PIM or any Purchaser to perform its obligations under this Agreement shall relieve any other Purchaser or the Company of any of its obligations hereunder, and neither PIM nor any Purchaser shall be responsible for the obligations of,
or any action taken or omitted by, any other such Person hereunder. 
  

	 	11P.	Counterparts. 

  
 This Agreement may be executed in any number of counterparts, each of which shall be an original, but all of which together shall constitute one
instrument. 
  

 56 

	 	11Q.	Binding Agreement. 

  
 When this Agreement is executed and delivered by the Company, on the one hand, and PIM and Prudential, on the other hand, it shall become a binding
agreement between the Company, on the one hand, and PIM and Prudential, on the other hand. This Agreement shall also inure to the benefit of each Purchaser which shall have executed and delivered a Confirmation of Acceptance, and each such Purchaser
shall be bound by this Agreement to the extent provided in such Confirmation of Acceptance. 
  

	 	11R.	Confidentiality. 

  
 For the purposes of this paragraph 11R, “Confidential Information” means information delivered to PIM or any Purchaser by or on behalf of
the Company or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when received by PIM or
such Purchaser as being confidential information of the Company or such Subsidiary; provided that such term does not include information that (a) was publicly known or otherwise known to PIM or such Purchaser prior to the time of such
disclosure, (b) subsequently becomes publicly known through no act or omission by PIM or such Purchaser or any Person acting on its behalf, (c) otherwise becomes known to PIM or such Purchaser other than through disclosure by the Company or any
Subsidiary or (d) constitutes financial statements delivered to PIM or such Purchaser under paragraph 5A that are otherwise publicly available. PIM and each Purchaser will maintain the confidentiality of such Confidential Information in accordance
with procedures adopted by it in good faith to protect confidential information of third parties delivered to it; provided that PIM or such Purchaser may deliver or disclose Confidential Information to (i) its directors, officers, employees,
agents, attorneys and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by its Notes), (ii) its financial advisors and other professional advisors who agree to hold confidential the
Confidential Information substantially in accordance with the terms of this paragraph 11R, (iii) any other holder of any Note, (iv) any Institutional Investor to which it sells or offers to sell such Note or any part thereof or any participation
therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this paragraph 11R), (v) any Person from which it offers to purchase any security of the Company (if such Person has
agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this paragraph 11R), (vi) any federal or state regulatory authority having jurisdiction over it, (vii) the National Association of Insurance
Commissioners or any similar organization, or any nationally recognized rating agency that requires access to information about its investment portfolio or (viii) any other Person to which such delivery or disclosure may be necessary or appropriate
(w) to effect compliance with any law, rule, regulation or order applicable to PIM or such Purchaser, (x) in response to any subpoena or other legal process, (y) in connection with any litigation to which PIM or such Purchaser is a party or (z) if
an Event of Default has occurred and is continuing, to the extent PIM or such Purchaser may reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under
its Notes and the other Transaction Documents. Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this paragraph 11R 

  

 57 

 
as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any holder of a Note of information
required to be delivered to such holder under this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Company embodying the provisions of
this paragraph 11R. 
  

	 	11S.	Jury Waiver. 

  
 THE COMPANY, PIM, PRUDENTIAL AND THE OTHER HOLDERS FROM TIME TO TIME OF THE NOTES AGREE TO WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR
CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT, ANY OTHER TRANSACTION DOCUMENT, OR ANY DEALINGS BETWEEN OR AMONG THEM RELATING TO THE SUBJECT MATTER OF THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY AND THE LENDER/BORROWER RELATIONSHIP
THAT IS BEING ESTABLISHED. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATTER OF THIS TRANSACTION, INCLUDING, WITHOUT LIMITATION, CONTRACT CLAIMS,

PURCHASERS AND EACH OF THE OTHER HOLDERS OF NOTES FROM TIME TO TIME FURTHER WARRANT AND REPRESENT THAT EACH HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL, AND THAT EACH KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION
WITH LEGAL COUNSEL. IN THE EVENT OF LITIGATION, THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT. 
  

	 	11T.	Personal Jurisdiction. 

  
 To the fullest extent permitted by law, the Company irrevocably agrees that any legal action or proceeding with respect to this Agreement, the Notes, the
other Transaction Documents or any of the agreements, documents or instruments delivered in connection herewith may be brought in the courts of the State of California, the State of New York, or the United States of America for the Northern District

 To the Holders of the Senior Notes

Named in 
 the Attached Schedule I 
  
 Ladies and Gentlemen: 
  
 Reference is made to (a) the Note Purchase Agreement dated as of November 15, 1997 (as in effect on the date hereof, the “1997 Note Purchase
Agreement”) among Northwest Pipe Company (the “Company”), and each of the Purchasers named in Schedule A thereto, pursuant to which the Company issued $35,000,000 aggregate principal amount of its 6.87% Senior Notes due November 15,
2007 (the “1997 Notes”), and (b) the Note Purchase Agreement dated as of April 1, 1998 (as in effect on the date hereof, the “1998 Note Purchase Agreement” and, together with the 1997 Note Purchase Agreement, collectively, the
“Note Purchase Agreements”), pursuant to which the Company issued $10,000,000 aggregate principal amount of its 6.63% 

 Series A Senior Notes, due April 1, 2005 (the “1998 Series A Notes”), and $30,000,000 aggregate principal
amount of its 6.91% Series B Senior Notes, due April 1, 2008 (the “1998 Series B Notes,” together with the 1998 Series A Notes, collectively, the “1998 Notes” and, the 1998 Notes, together with the 1997 Notes, collectively, the
“Notes”). You are referred to herein individually as a “Holder” and collectively as the “Holders.” Capitalized terms used and not otherwise defined herein shall have the meanings ascribed to them in the Note Purchase
Agreements, as amended hereby. 
  
 The Company and Wells Fargo
Bank, National Association (“Wells Fargo”) entered into a Credit Agreement, dated as of May 31, 2001, as amended, that is being amended and restated as of the date hereof (the “Credit Agreement”), pursuant to which Wells Fargo is
extending to the Company a master line of credit in the aggregate commitment amount of $35,000,000. 
  
 The Company, on the one hand, and Prudential Investment Management, Inc. (“PIM”), The Prudential Insurance Company of America
(“Prudential”), on the other hand, are entering into that Note Purchase and Private Shelf Agreement, dated as of the date hereof (the “Prudential Note Agreement”), pursuant to which the Company is issuing (a) to Prudential on the
date hereof the Company’s 8.75% senior secured promissory term notes due February 25, 2014 in the aggregate original principal amount of $15,000,000 (the “Prudential Series A Notes”), and (b) to PIM and certain Prudential affiliates
at a date in the future the Company’s senior secured promissory term notes in the aggregate principal amount of up to $25,000,000 (the “Prudential Shelf Notes” and, together with the Prudential Series A Notes, the “Prudential
Notes”). 
  
 The lenders party to the Credit Agreement (the
“Credit Agreement Lenders”), the Holders, the Company and the holders of the Prudential Notes (the “Prudential Noteholders”) have agreed that the obligations to the Credit Agreement Lenders under the Credit Agreement, the
obligations to the Holders with respect to the Notes and the obligations of the Prudential Noteholders with respect to the Prudential Notes shall be secured pari passu pursuant to certain security documents. Certain modifications to the Note
Purchase Agreements are necessary to make the obligations of the Company under the Notes pari passu with the obligations of the Company to the Prudential Noteholders. The Holders are willing to grant an amendment (hereinafter, this
“Amendment”) to effect such modifications on the terms and conditions set forth herein. 
  
 In consideration of the premises and for good and valuable consideration, the receipt and sufficiency of which are acknowledged, the Company and the
Holders agree as follows: 
  
 1. AMENDMENTS TO NOTE PURCHASE AGREEMENTS

  
 1.1. Amendment of Section 9. Section 9 of each of
the Note Purchase Agreements (except as otherwise specifically noted) is hereby amended by the addition of the following: 
  
 9.6 Most Favored Lender Status. If at any time any Principal Lending Agreement shall include any covenant, undertaking, restriction
or other provision (or any thereof shall be amended or otherwise modified) that is not contained in this Agreement or would be more beneficial to the holders of Notes than any analogous covenant, undertaking, restriction or provision contained in
this Agreement (any such covenant, 
  

 2 

 undertaking, restriction or provision, an “Additional Covenant”), then the Company shall
provide a Most Favored Lender Notice to the holders of the Notes. Thereupon, unless waived in writing by the Required Holders within five (5) days of receipt of such notice by the holders of the Notes, such Additional Covenant shall be deemed
automatically incorporated by reference into this Agreement, mutatis mutandis, as if set forth fully herein, without any further action required on the part of any Person, effective as of the date when such Additional Covenant became effective under
such Principal Lending Agreement. Thereafter, upon the request of the Required Holders, the Company shall enter into any additional agreement or amendment to this Agreement reasonably requested by such holder evidencing any of the foregoing. Any
Additional Covenant incorporated into this Agreement pursuant to this Section 9.6 shall remain unchanged herein notwithstanding any subsequent waiver, amendment or other modification of such Additional Covenant (unless any such waiver, amendment or
modification adds another Additional Covenant) under the applicable Principal Lending Agreement. 
  
 9.7 Payments on the Notes. 
  
 (a) 1997 Notes. Interest and supplemental interest, if any, on the unpaid balance of each Note shall be payable quarterly on May
15, August 15, November 15 and February 15 in each year, commencing with the May 15 next succeeding the date hereof, until the principal hereof shall have become due and payable. 
  
 (b) 1998 Notes. Interest and supplemental interest, if any, on the unpaid balance of each Note shall
be payable quarterly on January 1, April 1, July 1 and October 1 in each year, commencing with the April 1 next succeeding the date hereof, until the principal hereof shall have become due and payable. 
  
 (c) Supplemental Interest Rate. Commencing on
February 25, 2004 and for each quarter thereafter, the rate of interest payable on each Note shall be adjusted (the “Supplemental Interest Rate”) to reflect the ratio of the Company’s Consolidated Total Debt to Consolidated EBITDA
(calculated on a rolling twelve-month basis) (the “Leverage Ratio”) as set forth in the chart below (such rate adjustment will be an adjustment to (and not in place of) the Company’s existing interest rate on each Note): 

 

			
	 Ratio of Consolidated Total Debt/
 Consolidated EBITDA

	  	 Supplemental
 Interest Rate

	 > 3.50:1
	  	1.50%
	 > 2.75:1 and <= 3.50:1
	  	0.75%
	 <= 2.75:1
	  	0.00%

  
 The
calculation of the supplemental interest for the period from February 25, 2004 to and including March 31, 2004 will be prorated based on the actual number of days elapsed and on the basis of a 360-day year and will be calculated using the
Supplemental Interest Rate as determined by the Leverage Ratio as of December 31, 2003. Thereafter, the Supplemental Interest Rate will be adjusted at the beginning of each fiscal quarter for such fiscal quarter based on the Leverage Ratio as
determined as of 
  

 3 

 the last day of the immediately preceding fiscal quarter. Interest and the supplemental interest
calculated at the Supplemental Interest Rate will be paid on the interest payment dates set forth in Section 9.7(a) for the 1997 Notes and will be paid on the interest payment dates set forth in Section 9.7(b) for the 1998 Notes until the principal
hereof shall have become due and payable. 
  
 (d)
Notices. Commencing on May 15, 2004, and on the 60th calendar day of each calendar quarter thereafter, the
Company will notify each holder of a Note of the Leverage Ratio for the most recently ended fiscal quarter, together with the associated Supplemental Interest Rate for the for the respective fiscal quarter; provided that such date shall
automatically be extended to the date the Bank extends such date under Section 4.3(c) of the Bank Credit Agreement and the Company shall promptly notify each holder of a Note in writing of such extension by the Bank but in no event shall such date
be extended for purposes of this Section 9.7(d) to a date later than the 90th day of each calendar quarter. 
  
 (e) Amendments. Each of the amendments set forth in this Section 9.7 shall be effective without the reissuance of any of the
existing Notes. To the extent that any new Notes are issued after the date hereof, or should any existing Notes be reissued for any reason, the amendments set forth in this Section 9.7 shall be reflected in such newly-issued or reissued Notes.

  
 9.8 Subsequent Guarantors. Within 10
days after any Credit Party’s acquisition or formation of a Person that becomes a Major Domestic Subsidiary or within 10 days after any determination that any Domestic Subsidiary has become a Major Domestic Subsidiary, or (ii) concurrently with
any Subsidiary’s becoming a guarantor or co-obligor of any of the Secured Obligations (as defined in the Intercreditor Agreement), the Company will cause such Person to (a) become a party to the Subsidiary Guaranty, the Indemnity and
Contribution Agreement, the Security Agreement (or an additional security agreement substantially similar to the Security Agreement) and the Intercreditor Agreement and (b) execute and deliver to each holder of Notes such opinions of counsel,
certificates accompanying authorizing resolutions and corporate or similar documents, and such other financing statements, landlord/mortgagee waivers and other agreements, instruments and other documents as the Required Holders may reasonably
request, each of foregoing in form and substance satisfactory to the Required Holders. Notwithstanding the foregoing, within 10 days after any determination by the Required Holders that (1) the book value of the assets of the Company (exclusive of
its Subsidiaries), together with the book value of the assets of any then existing parties to the Subsidiary Guaranty, in each case as at the end of the most recently ended fiscal quarter, do not collectively constitute at least 90% of the book
value of the assets of the Company and its Subsidiaries on a consolidated basis as at the end of the most recently ended fiscal quarter, or (2) the Consolidated EBITDA (determined solely with respect to the Company (exclusive of its Subsidiaries)),
together with the Consolidated EBITDA determined solely with respect to any then existing parties to the Subsidiary Guaranty, in each case for the most recently ended four consecutive fiscal quarters, does not collectively constitute at least 90% of
the Consolidated EBITDA for the most recently ended four consecutive fiscal quarters, then the Company shall cause such Domestic Subsidiaries to 
  

 4 

 execute and deliver to each holder of Notes the documents described in clauses (a) and (b) of the
immediately preceding sentence so that (A) the book value of the assets of the Company (exclusive of its Subsidiaries) and the parties to the Subsidiary Guaranty constitute at least 90% of the book value of the assets of the Company and its
Subsidiaries on a consolidated basis and (B) the Consolidated EBITDA (determined solely with respect to the Company (exclusive of its Subsidiaries)), together with the Consolidated EBITDA determined solely with respect to any then existing parties
to the Subsidiary Guaranty collectively constitute at least 90% of the Consolidated EBITDA. 
  
 1.2. Amendment of Section 10. Section 10 of each of the Note Purchase Agreements is hereby amended and restated in its entirety as follows:

  
 The Company covenants that so long as any of the Notes are
outstanding: 
  
 10.1 Financial Covenants.
