Item 2. Acquisition or Disposition of Assets

         On May 31, 1996, Northwest Pipe Company (the "Company") acquired
Thompson Pipe and Steel Company ("Thompson"), a manufacturer of water
transmission pipe headquartered in Denver, Colorado. The acquisition (the
"Acquisition") was accomplished through the Company's purchase of all of the
issued and outstanding capital stock of Thompson from Inter-City Products
Corporation, a Canadian corporation based in Toronto, Canada, and its affiliates
("ICP").

         The purchase price paid by the Company for the capital stock of
Thompson was approximately $3.0 million, subject to adjustment based on a
post-closing balance sheet to be completed by June 30, 1996. In addition, the
Company purchased from ICP certain indebtedness of Thompson to ICP in the amount
of approximately $4.8 million. The purchase price was determined through
arms-length negotiations between the Company and ICP. The funds used to pay the
purchase price were obtained pursuant to the terms of the Company's Amended and
Restated Financing Agreement with The CIT Group/Business Credit, Inc. dated as
of May 31, 1996.

         The principal assets acquired by the Company in the Acquisition were
steel pipe manufacturing facilities located in Denver, Colorado and Princeton,
Kentucky. The Kentucky manufacturing facility was closed by Thompson in 1995.
The Company intends to continue operating the manufacturing facility in Denver,
Colorado, and intends to dispose of the manufacturing facility located in
Princeton, Kentucky.

                                    ARTICLE 2

                         SALE AND PURCHASE OF SHARES AND
                    PURCHASED NET INTERCOMPANY INDEBTEDNESS;
                           PURCHASE PRICE ADJUSTMENT;
                          PAYMENT OF THE PURCHASE PRICE

2.1 SALE AND PURCHASE

         Subject to the terms and conditions of this Agreement, on the Closing
Date, (i) CHL shall sell the Shares to Buyer and Buyer shall purchase the Shares
from CHL, and (ii) CHL shall sell the Purchased Net Intercompany Indebtedness to
Buyer, and Buyer shall purchase from CHL the Purchased Net Intercompany
Indebtedness.

2.2 PURCHASE PRICE

         The term the "Purchase Price" means $4,478,000 plus the amount of the
Purchased Net Intercompany Indebtedness. The Purchase Price allocated to the
Shares shall be subject to adjustment by the Purchase Price Adjustment, if any.

2.3 PHYSICAL INVENTORY; AUDIT; CLOSING BALANCE SHEET

         2.3.1 There shall be conducted by Seller and observed by Seller's
Accountants, Buyer and Buyer's Accountants a physical taking of the Company's
and Thompson Sub's inventory commencing at 8:00 A.M., local time, on the day
after the day in which the Effective Time occurs, at all of the Company's and
Thompson Sub's facilities, wherever located. With respect to any inventory of
the Company and Thompson Sub located at any premises not owned or leased by
either of them, Seller or Seller's Accountants shall obtain from an appropriate
representative of each Person who is in possession of any such off-site
inventory, written certification as to the amount of such off-site inventory as
of such date. The valuation of inventory will be computed by Seller's
Accountants in accordance with GAAP and with the practices and procedures and
other methods (including, without limitation, the method of computing overhead
and other indirect expenses to be applied to inventory) used in computing the
value of inventory for purposes of preparation of the Consolidated Financial
Statements (except to the extent inconsistent with GAAP).

         2.3.2 As promptly as possible after the Closing, Seller shall cause
Seller's Accountants to conduct an audit (the "Audit") of the consolidated
balance sheet (the "Closing Balance Sheet") for the Consolidated Group, which
Closing Balance Sheet shall be prepared as of the Effective Time in accordance
with GAAP and on the assumption that the Company will carry on its business in
the ordinary course consistent with past practice, provided, however, that such
assumption shall in no way restrict Buyer or the Company in the operation of the
Company's business. For purposes of the Audit, the aggregate "materiality" level
shall be $200,000. Notwithstanding any materiality level, any and all
adjustments identified as a result of the Audit shall be recorded and reflected
in the Closing Balance Sheet.

11 - STOCK PURCHASE AGREEMENT
<PAGE>   17
         2.3.3 Buyer shall pay Seller's Accountants for all expenses and fees of
Seller's Accountants in connection with the conduct of the physical inventory
and the Audit pursuant to this Section 2.3, and these expenses and fees shall
not be reflected in the calculation of Equity for the Closing Balance Sheet.

         2.3.4 As promptly as reasonably practicable and, in any event, not
later than thirty (30) days after the Closing Date, the Company will deliver to
the Seller and Seller's Accountants a draft of the Closing Balance Sheet. As
promptly as possible thereafter and, in any event, not later than fifty (50)
days after the Closing Date Seller shall deliver to Buyer the Closing Balance
Sheet, together with the Seller's Accountants' report. The management
representations made by Seller in connection with the Audit shall by this
reference be deemed to have also been made to Buyer and are incorporated into
and made a part of this Agreement. The Closing Balance Sheet shall be
accompanied by a written representation of Seller that, to the Knowledge of ICP
and CHL, there is no basis for any liability or obligation (absolute, accrued,
contingent or otherwise) which is of a type that should be reflected in a
balance sheet prepared in accordance with GAAP and which is not reflected on the
Closing Balance Sheet. If Buyer does not object in writing to the Closing
Balance Sheet within ten (10) days after delivery to Buyer, such Closing Balance
Sheet shall automatically become final and conclusive for purposes of
calculation of the Purchase Price Adjustment; any such written objection (the
"Objection Notice") shall set out the reasons for Buyer's objection, the amount
in dispute (if determinable), and the basis for the calculation of such amount
(if determinable). In the event that Buyer properly objects in writing to the
Closing Balance Sheet within said 10-day review period, Seller and Buyer shall
promptly meet and endeavor to reach agreement as to the content of the Closing
Balance Sheet for purposes of calculation of the Purchase Price Adjustment. If
Seller and Buyer agree in writing on the content of the Closing Balance Sheet,
such Closing Balance Sheet shall become final and conclusive for purposes of
calculation of the Purchase Price Adjustment.

         2.3.5 If Buyer and Seller are unable to settle any dispute with respect
to the Closing Balance Sheet within ten (10) days after the delivery by Buyer to
Seller of the Objection Notice, the dispute shall be referred to arbitration by
a single arbitrator, if such parties can agree upon one arbitrator, or otherwise
by three arbitrators, of whom one shall be appointed by Buyer and one shall be
appointed by Seller and the third shall be chosen by the first two named
arbitrators. The arbitration and the appointment of the arbitrator shall, except
to the extent provided for in this Section, be conducted in Denver, Colorado in
accordance with the Colorado Uniform Arbitration Act of 1975, C.R.S. 13.22-201,
et. seq. Buyer and Seller shall cooperate in completing any arbitration as
expeditiously as possible and the arbitrators may hire such experts as may
appear to be appropriate. If a single arbitrator is used, all of the costs and
expenses of the arbitration shall be borne equally by Buyer and Seller or in
such other manner as the arbitrator may determine to be appropriate. If three
arbitrators are used, the costs and expenses of the third arbitrator and any
experts engaged by such arbitrator shall be borne equally by Buyer and Seller
and each such party shall pay the costs and expenses of the arbitrator appointed
by it. Each arbitrator shall be an audit partner with a "Big Six" certified
public accounting firm other than Seller's Accountants or Buyer's Accountants.
Arbitration under this Section 2.3 shall be in substitution for and precludes
the bringing of any Proceeding in any court in connection with any objection
made by Buyer pursuant to this Section.

12 - STOCK PURCHASE AGREEMENT
<PAGE>   18
         2.3.6 The determination of the arbitrator(s) shall be made within
thirty (30) days after the date on which the dispute was referred to arbitration
and the determination of the arbitrator(s) shall be final and binding on all
parties. The Closing Balance Sheet and the Purchase Price shall be adjusted in
accordance with the determination of the arbitrator(s).

         2.3.7 In addition to other adjustments to the Closing Balance Sheet
made pursuant to this Section 2.3, subject to Section 2.4.3(iv)(2), the parties
agree that the Closing Balance Sheet shall be adjusted by Sellers' Accountants
upon the reasonable request of Buyer provided that the adjustment is consistent
with GAAP and does not have an adverse effect on Seller.

2.4 PURCHASE PRICE ADJUSTMENT

         2.4.1 The Purchase Price set out in Section 2.2 shall be increased or
decreased (the "Purchase Price Adjustment") on a dollar-for-dollar basis by an
amount equal to the increase or decrease, if any, in Equity from December 31,
1995 (as reflected in the 1995 Financial Statements) to the Effective Time (as
reflected in the Closing Balance Sheet).

         2.4.2 Subject to Section 2.4.3 (ii) and (iii) below, the term "Equity"
means the sum of the following, in each case determined as of the relevant date
on a consolidated basis for the Consolidated Group:

                           (i) Shareholders' equity, determined in accordance
         with GAAP, plus

                           (ii) Net Intercompany Indebtedness other than the
         Purchased Net Intercompany Indebtedness.

         2.4.3 The parties further agree that:

                           (i) "Equity" as of December 31, 1995 based upon the
         1995 Financial Statements was $8,863,000, consisting of $2,274,000 in
         shareholders' equity and $6,589,000 in Net Intercompany Indebtedness;

                           (ii) Any change in "Equity" resulting from the sale
         or contemplated sale of the assets of Thompson Sub as described in
         Schedule 2.4.3(ii) shall be disregarded in determining the Purchase
         Price Adjustment; and

                           (iii) Any change in "Equity" resulting from
         write-downs with respect to property, plant and equipment located at
         Thompson Sub's Princeton, Kentucky facility, consisting of the land,
         buildings, tape coating line, propane tank line and other property,
         plant and equipment located at such facility, all as set forth in
         Schedule 2.4.3(iii), shall be disregarded in determining the Purchase
         Price Adjustment.

13 - STOCK PURCHASE AGREEMENT
<PAGE>   19
                           (iv) Any change in Equity from December 31, 1995 to
         the Effective Time, resulting from any of the following shall be
         disregarded in determining the Purchase Price Adjustment:

                                      (1) The amortization of the deferred
         financing fee for the Congress Financial Corporation credit facilities.

                                      (2) Any change in Equity resulting from an
         adjustment to the Closing Balance Sheet requested by Buyer pursuant to
         Section 2.3.7.

                                      (3) Any increases in the recorded value of
         any intangible asset.

         2.4.4 Notwithstanding Section 2.3.2, the Purchase Price shall not be
increased by the amount of any net tax asset recorded on the Closing Balance
Sheet or by the amount of any tax benefits of Losses or expenses suffered or
incurred by a Member of the Consolidated Group.

2.5 PAYMENTS BY BUYER

         Buyer shall pay the Purchase Price and the Purchase Price Adjustment as
follows:

         2.5.1 On the Closing Date, Buyer shall pay to Seller an amount equal to
the Purchase Price minus the sum of (i) $1,500,000 and (ii) the Escrow Funds,
(the "Closing Date Payment"). The Closing Date Payment shall be paid by wire
transfer to an account designated by Seller to Buyer in writing not less than
three (3) days prior to the Closing Date.

eight and one-quarter percent (8.25%) per annum, (without recourse to the Escrow

(A) pursuant to which any Member of the Consolidated Group has any material
liability or (B) constituting an employment or severance agreement or

to any Employee Plan, has engaged directly or indirectly in any "prohibited
transaction," as such term is defined in Section 4975 of the Code or Section 406

         5.10.5 No Employee Plan has been the subject of an IRS or Department of
Labor audit. There are no Pending Proceedings or, to the Warranting Parties'
Knowledge, threatened Proceedings in which the "qualified" status of any
Employee Plan is at issue and in which revocation of the determination letter
has been threatened. Each such Employee Plan has not been amended or operated,
since the receipt of the most recent determination letter, in a manner that

No distributions have been made from any of the Employee Plans that would
violate in any material respect the restrictions under Treas. Reg. Section
1.401(a)(4)-5(b), and none will have been made by the Closing Date. To the
Warranting Parties' Knowledge, there has been no

adequate accruals therefore have been provided for in the Consolidated Financial
Statements.

         5.10.7 The Transaction (either alone or together with any additional or
subsequent events) does not constitute an event under any Employee Plan, Benefit
Arrangement or individual Employee Contract, that may result in any payment
(whether of severance pay or otherwise), restriction or limitation upon the
assets of any Employee Plan or Benefit Agreement, acceleration of payment or
vesting, increase in benefits or compensation, or required funding, with respect
to any Employee, or the forgiveness of any loan or other commitment of any
Employee.

         5.10.8 To the Warranting Parties' Knowledge, no amounts paid or payable
by any Member of the Consolidated Group to or with respect to any Employee will
fail to be deductible for federal income tax purposes by reason of Section 280G
of the Code.

or may become entitled under any Employee Plan or Benefit Arrangement to
post-employment welfare benefits of any kind, including, without limitation,
death or medical benefits, other than coverage mandated by Section 4980B of the
Code.

         5.10.10 The Employee Plans that are group health plans (as defined for
the purposes of Section 4980B of the Code and Part 6 of Subtitle B of Title I of
ERISA, and all regulations thereunder, (such provisions of law and regulations
are hereinafter referred to as "COBRA")) have complied in all material respects
at all times during the past three (3) years with requirements of COBRA to
provide health care continuation coverage to qualified beneficiaries who have
elected, or may elect to have, such coverage. The Consolidated Group Members and
their agents who administer any of the Employee Plans or Benefit Arrangements,
have complied in all material respects at all times during the past three (3)
years and will continue to comply in all material respects through the Effective
Time, with the notification and written notice requirements of COBRA. There are

any current Employee, former Employee, participants or by the beneficiary,
dependent or representative of any such person, involving the failure of any
Employee Plan or Benefit Arrangement or of any other group health plan ever
maintained by any Member of the Consolidated Group to comply with the health
care continuation coverage requirements of COBRA.

petitions have been pending at any time within two years of the date of this

12.6     NOTIFICATION AND DEFENSE OF CLAIMS OR ACTIONS

         12.6.1 As used in this Section, any party seeking indemnification
pursuant to this Article 12 is referred to as an "Indemnified Party" and any
party from whom indemnification is sought pursuant to this Section is referred
to as an "Indemnity Obligor." An Indemnified Party which proposes to assert (i)
the right to be indemnified under this Article 12, or (ii) that a claim is, or
could give rise to, an Escrow Liability for purposes of Section 12.3 shall,
pursuant to the notice provisions of this Agreement, submit a written demand for
indemnification setting forth in summary form the facts as then known which form
the basis for the claim for indemnification, including, if relevant to the
rights of the Indemnified Party under this Article 12, the basis for determining
that a Loss was within the Knowledge of any party.

         12.6.2 With respect to claims based on actions by third parties, an
Indemnified Party shall, within twenty (20) days after the receipt of notice of
the commencement of any Proceeding against it in respect of which a claim for
indemnification is to be made against an Indemnity Obligor or which the
Indemnified Party proposes to assert is an Escrow Liability, notify the
Indemnity Obligor in writing of the commencement of such Proceeding, enclosing a
copy of all papers served; provided, however, that the failure to so notify the
Indemnity Obligor of any such Proceeding shall not relieve the Indemnity Obligor
from any liability which it may have to the Indemnified Party, except to the
extent that the Indemnity Obligor is prejudiced thereby. Thereafter, the
Indemnified Party shall deliver to the Indemnity Obligor, within ten (10) days
after receipt by the Indemnified Party, copies of all further notices relating
to such claim.

         12.6.3 If a third-party claim is made for which an Indemnified Party is
entitled to indemnification pursuant to Sections 12.2, 12.4 or 12.5, the
Indemnity Obligor will be entitled to participate in the defense of such claim.
If the Indemnity Obligor so chooses, and provided that it acknowledges in
writing its obligation to indemnify the Indemnified Party, the Indemnity Obligor
may assume primary responsibility for the defense of such claim with counsel
selected by the Indemnity Obligor and not reasonably objected to by the
Indemnified Party. Should the

58 - STOCK PURCHASE AGREEMENT
<PAGE>   64
Indemnity Obligor assume primary responsibility for the defense of any such
claim, the Indemnity Obligor will not be liable to the Indemnified Party for any
legal expenses subsequently incurred by the Indemnified Party in connection with
the defense of such claim.

         12.6.4 If the Indemnity Obligor assumes the defense of a third-party
claim as set forth in Section 12.6.3, then (i) in no event will an Indemnified
Party admit any liability with respect to, or settle, compromise or discharge,
any such claim without the Indemnity Obligor's prior written consent and (ii)
each Indemnified Party shall be entitled to participate in, but not control, the
defense of such claim with its own counsel at its own expense. If the Indemnity
Obligor does not assume the defense of any such claim, an Indemnified Party may
defend such claim in a manner as it may deem appropriate (including, but not
limited to, settling such claim, after giving twenty (20) days prior written
notice of such settlement to the Indemnity Obligor, on such terms as the
Indemnified Party may deem appropriate).

         12.6.5 If a third-party claim is made which is, or could give rise to,
an Escrow Liability, then the following shall apply:

                  (a) In the case of a third-party claim which is or could give
rise to an Unknown Contingent Liability:

                           (i) if the amount of such claim plus the sum of (A)
         all prior Losses suffered or incurred by Buyer and the Company with
         respect to Unknown Contingent Liabilities, and (B) the amount of all
         other claims then Pending which are, or could give rise to, Unknown
         Contingent Liabilities (collectively, "Aggregate Potential Unknown
         Contingent Liability Losses"), is wholly within the Unknown Contingent
         Liability Indemnity Deductible, Buyer shall be primarily responsible
         for the defense of such claim, Seller will be entitled, but not
         obligated, to participate in the defense of such claim and Buyer will
         not settle the claim without Seller's prior written consent, which
         consent shall not be unreasonably withheld or delayed.

                           (ii) If the amount of such claim plus all Aggregate
         Potential Unknown Contingent Liability Losses, is greater than the
         Unknown Contingent Liability Indemnity Deductible, so long as there
         remain Escrow Funds subject to the Escrow Agreement, Seller will be
         entitled, but not obligated, to assume joint responsibility with Buyer
         for the defense of the claim. Neither party will settle such a claim
         without the prior written consent of the other party, which consent
         shall not be unreasonably withheld or delayed.

                  (b) In the case of a third-party claim which is or could give
rise to an Environmental Liability, so long as there remain Escrow Funds subject
to the Escrow Agreement, Seller will be entitled, but not obligated, to assume
joint responsibility with Buyer for the defense of the claim. Neither party will
settle such a claim without the prior written consent of the other party, which
consent shall not be unreasonably withheld or delayed.

59 - STOCK PURCHASE AGREEMENT
<PAGE>   65
         12.6.6 In the event that any claim for indemnification is made with
respect to any third-party claim pursuant to this Article, (i) the party
assuming primary responsibility for the defense of such claim shall at all times
keep the other party informed as to the status of such claim and (ii) the party
not primarily responsible for the defense of such claim shall cooperate fully
with the other party in connection with such defense.

12.7     USE OF ESCROW FUNDS FOR INDEMNIFICATION

         12.7.1 In the event that Buyer is entitled to indemnification from
Seller pursuant to Section 12.3, Seller's obligations shall be satisfied solely
out of the Escrow Funds in accordance with the terms and conditions of the
Escrow Agreement.

         12.7.2 In the event that Buyer is entitled to indemnification from
Seller pursuant to Section 12.2, Buyer shall be entitled to payment from, but
shall not be required to obtain payment from, available Escrow Funds in
accordance with the terms and conditions of the Escrow Agreement.

12.8     RELIANCE

         No disclosure by any party ("Disclosing Party") to this Agreement nor
any investigation made by or on behalf of another party with respect to the
Disclosing Party shall be deemed to affect the other party's reliance on the
respective representations and-warranties contained in this Agreement and no
such disclosure shall constitute a waiver of that party's rights to indemnity as
herein provided for the breach of any of said representations and warranties;
provided, however, to the extent that as a result of any such investigation, an
officer or director of the non-Disclosing Party has actual knowledge that any
representation or warranty is untrue and the Disclosing Party does not have
Knowledge that such representation or warranty is untrue, the Disclosing Party
shall have no liability with respect to such breach of representation or
warranty.

Each borrowing by the Companies hereunder shall constitute a representation and
warranty by the Companies as of the date of such loan or advance that each of
the representations, warranties and covenants contained in this Financing
Agreement have been satisfied and are true and correct, except as the Companies
and CITBC shall otherwise agree herein or in a separate writing.

SECTION 3.  REVOLVING LOANS

                   3.1 (A) CITBC agrees, subject to the terms and conditions of
this Financing Agreement from time to time, and within x) the Northwest Pipe
Availability and y) in the aggregate with Revolving Loans to Thompson Pipe, the
Revolving Line of Credit, but subject to CITBC's right to make "overadvances"
(defined below), to make loans and advances to Northwest Pipe on a revolving
basis (i.e. subject to the limitations set forth herein, Northwest Pipe may
borrow, repay and re-borrow Revolving Loans). Such loans and advances shall be
in amounts up to the sum of: (i) eighty-five percent (85%) of the outstanding
Eligible Northwest Pipe Accounts Receivable (including bill-and-hold Accounts),

Northwest Pipe Inventory as determined at the lower of cost or market.

                   (B) CITBC agrees, subject to the terms and conditions of this
Financing Agreement from time to time, and within x) the Thompson Pipe
Availability and y) in the aggregate with Revolving Loans to Northwest Pipe, the
Revolving Line of Credit, but subject to CITBC's right to make "overadvances"
(defined below), to make loans and advances to Thompson Pipe on a revolving
basis (i.e. subject to the limitations set forth herein, Thompson Pipe may
borrow, repay and re-borrow Revolving Loans). Such loans and advances shall be
in amounts up to the sum of: (i) eighty-five percent (85%) of the outstanding
Eligible Thompson Pipe Accounts Receivable (including bill-and-hold Accounts),

<PAGE>   37
                   (C) Notwithstanding the foregoing, (i) advances against total
Eligible Inventory and Unbilled Accounts Receivable shall not exceed $16,000,000
in the aggregate at any one time. All requests for loans and advances must be
received by an officer of CITBC no later than 2:00 p.m. New York time of the day
on which such loans and advances are required. Should CITBC for any reason honor
requests for advances in excess of the limitations set forth herein, such
advances shall be considered "overadvances" and shall be made in CITBC's sole
discretion, subject to any additional terms CITBC deems necessary.

                   (D) Unless otherwise agreed to in writing by CITBC, no
Revolving Loans shall be made to Thompson Steel.

                   3.2 (A) In furtherance of the continuing assignment and
security interest in the Companies' Accounts, the Companies will, upon the
creation of Accounts, execute and deliver to CITBC in such form and manner as
CITBC may reasonably require, solely for CITBC's convenience in maintaining
records of collateral, such confirmatory schedules of Accounts as CITBC may
reasonably request, and such other appropriate reports designating, identifying
and describing the Accounts as CITBC may reasonably require. In addition, upon
CITBC's request the Companies shall provide CITBC with copies of agreements
with, or purchase orders from, the Companies' customers, and copies of invoices
to customers, proof of shipment or delivery and such other documentation and
information relating to said Accounts and other collateral as CITBC may
reasonably require. Failure to provide CITBC with any of the foregoing shall in
no way affect, diminish, modify or otherwise limit the security interests
granted herein. The Companies hereby authorize CITBC to regard any Company's
printed name or rubber stamp signature on assignment schedules or invoices as
the equivalent of a manual signature by one of such Company's authorized
officers or agents.

                   (B) The obligation of the Companies to repay the principal
amount of the Revolving Loans made pursuant to this Section 3 and pursuant to
any Letter of Credit Guaranty issued pursuant to Section 5 by CITBC and to pay
interest thereon shall be evidenced in part by Promissory Notes in the form of
Exhibit C attached hereto. Each Company's outstanding Obligations applicable
thereto may be set forth in the balance column on the

                                       34

<PAGE>   38
grid page attached to said note or on the separate ledgers maintained by CITBC.
All such advances, whether or not so recorded, shall be due as part of said
note. Promissory Notes executed by each of Northwest Pipe and Thompson Pipe
shall be delivered to CITBC on the Closing Date.

         3.3 Each Company hereby represents and warrants that: each Account is
based on an actual and bona fide sale and delivery of goods or rendition of
services to customers, made by such Company in the ordinary course of its
business; the goods and inventory being sold and the Accounts created are the
exclusive property of such Company and are not and shall not be subject to any
lien, consignment arrangement, encumbrance, security interest or financing
statement whatsoever, other than the Permitted Encumbrances; the invoices
evidencing such Accounts are in the name of such Company; and the customers of
such Company have accepted the goods or services, owe and are obligated to pay
the full amounts stated in the invoices according to their terms, without
dispute, offset, defense, counterclaim or contra, except for disputes and other
matters arising in the ordinary course of business of which such Company has
advised CITBC pursuant to paragraph 5 of this Section 3. Each Company confirms
to CITBC that any and all taxes or fees relating to its business, its sales, the
Accounts or goods relating thereto, are its sole responsibility and that same
will be paid by such Company when due and that none of said taxes or fees
represent a lien on or claim against the Accounts. Each Company also warrants
and represents that it is a duly and validly existing corporation and is
qualified in all states where the failure to so qualify would have an adverse
effect on the business of such Company or the ability of such Company to enforce
collection of Accounts due from customers residing in that state. Each Company
agrees to maintain such books and records regarding Accounts as CITBC may
reasonably require and agrees that the books and records of such Company will
reflect CITBC's interest in the Accounts. All of the books and records of the
Companies will be available to CITBC at normal business hours, including any
records handled or maintained for the Companies by any other company or entity.

         3.4 Until CITBC has advised the Companies to the contrary after the
occurrence of an Event of Default, the


                                       35
<PAGE>   39
Companies may and will enforce, collect and receive all amounts owing on the
Accounts for CITBC's benefit and on CITBC's behalf, but at the Companies'
expense; such privilege shall terminate automatically upon the institution by or
against any Company of any proceeding under any bankruptcy or insolvency law or,
at the election of CITBC, upon the occurrence of any other Event of Default and
until such Event of Default is waived or cured to CITBC's satisfaction. The
Companies shall direct all of their account debtors to deposit any and all
proceeds of Collateral into the Depository Account (as defined below), and any
checks, cash, notes, chattel paper or other instruments or property received by
the Companies with respect to any Accounts shall be held by the Companies in
trust for CITBC, separate from the Companies' own property and funds, and
immediately turned over to CITBC with proper assignments or endorsements by
deposit to the special depository accounts in CITBC's name designated by CITBC
for such purposes (the "Depository Accounts"). All amounts received by CITBC in
payment of Accounts will be credited to the applicable Company's accounts upon
CITBC's receipt of "collected funds" at CITBC's bank account in New York, New
York on the Business Day of receipt if received no later than 1:00 pm or on the
next succeeding Business Day if received after 1:00 pm. No checks, drafts or
other instrument received by CITBC shall constitute final payment to CITBC
unless and until such instruments have actually been collected.

         3.5 The Companies agree to notify CITBC promptly of any matters
materially affecting the value, enforceability or collectibility of any Account
and of all material customer disputes, offsets, defenses, counterclaims,
returns, rejections and all reclaimed or repossessed merchandise or goods. The
Companies agree to issue credit memoranda promptly (with duplicates to CITBC
upon request after the occurrence of an Event of Default) upon accepting returns
or granting allowances, and may continue to do so until CITBC has notified the
Companies that an Event of Default has occurred and that all future credits or
allowances are to be made only after CITBC's prior written approval. Upon the
occurrence of an Event of Default and until such time as such Event of Default
is waived or cured to CITBC's satisfaction and on notice from CITBC, the
Companies agree that all returned, reclaimed or repossessed merchandise or goods
shall 

                                       36
<PAGE>   40
be set aside by the Companies, marked with CITBC's name (as secured party) and
held by the Companies for CITBC's account.

         3.6 CITBC shall maintain separate accounts on its books in each
Company's name in which such Company will be charged with loans and advances
made by CITBC to it or for its account, and with any other Obligations,
including any and all costs, expenses and reasonable attorney's fees which CITBC
may incur in connection with the exercise by or for CITBC of any of the rights
or powers herein conferred upon CITBC, or in the prosecution or defense of any
action or proceeding to enforce or protect any rights of CITBC in connection
with this Financing Agreement, the other Loan Documents or the Collateral
assigned hereunder, or any Obligations owing to CITBC by the Companies. Each
Company will be credited with all amounts received by CITBC from such Company or
from others for such Company's account, including, as above set forth, all
amounts received by CITBC in payment of assigned Accounts and such amounts will
be applied to payment of the Obligations. In no event shall prior recourse to
any Accounts or other security granted to or by the Companies be a prerequisite
to CITBC's right to demand payment of any Obligation. Further, it is understood
that CITBC shall have no obligation whatsoever to perform in any respect any of
the Companies' contracts, lease agreements or obligations relating to the
Accounts.

         3.7 After the end of each month, CITBC shall promptly send the
Companies one or more statements showing the accounting for the charges, loans,
advances and other transactions occurring between CITBC and each Company during
that month. The monthly statements shall be deemed correct and binding upon the
Companies and shall constitute an account stated between the Companies and CITBC
unless CITBC receives a written statement of the exceptions within thirty (30)
days of the date of the monthly statement.

                $4,000,000.00 in the aggregate at any time.

         d)     Northwest Pipe and Thompson Pipe must give CITBC at least thirty
                (30) days' prior written notice of its intention to enter into a

                appraisals, invoices, purchase orders, and/or other contracts
                and any additional information CITBC may request with respect to

                Pipe to purchase assets on which CITBC has a first lien
                position, and such assets shall not constitute an attachment,
                accessory, accession, replacement, substitution, addition or
                improvement of any Equipment, fixture or line on which any other
                creditor has a first lien position;

         h)     Capex Loans may only be requested by Northwest Pipe and Thompson
                Pipe during the period commencing on the Closing Date and
                expiring at 2:00 p.m. (New York City time) on the third

                                       39
<PAGE>   43
         i)     Each of Northwest Pipe and Thompson Pipe may request no more
                than one (1) Capex Loan during any calendar quarter. Unless
                otherwise agreed to in writing by CITBC, Thompson Steel may not
                request Capex Loans.

         j)     Northwest Pipe and Thompson Pipe may request, and CITBC agrees
                to make, any such Capex Loans as aforesaid absent the occurrence
                of a Default which has not been waived in writing by CITBC or
                cured to the satisfaction of CITBC or an Event of Default which
                has not been waived in writing by CITBC.

         4.2 Each Capex Loan will be repaid to CITBC by the applicable Company
in equal quarterly installments of principal computed on a five (5) year
amortization schedule, whereby the installments shall commence on the last day
of the first fiscal quarter following the advance of the Capex Loan, and shall
continue to be paid on the last day of each fiscal quarter thereafter until paid

and the amount of each repayment received by CITBC, provided that any failure by
CITBC to make any such entry shall not affect the obligations of the Companies
hereunder or under the Capex Promissory Note(s) or otherwise in respect of the
Capex Loan(s). All entries made by CITBC including notations on any schedule to
the Capex Promissory Note(s) or in the internal records of CITBC (computer or
otherwise) shall be deemed correct in the absence of manifest error.

<PAGE>   44
         4.5 Each Company may prepay at its option, in whole or in part, the
Capex Loans; provided, that on each such prepayment, such Company shall pay x)
accrued interest on the principal so prepaid to the date of such prepayment and
y) the Libor Prepayment Penalty, if applicable.

         4.6 Each voluntary and mandatory prepayment shall be applied to the
last maturing installments of principal of any Capex Loan designated by the
Companies until paid in full; provided, however, if the Companies do not so
designate a Capex Loan, then CITBC may apply such prepayment to a Capex Loan of
its choosing.

         4.7 Each Company hereby authorizes CITBC to charge its Revolving Loan
Account with the amount of all principal, interest, fees and any other amounts
due under this Section 4 as such amounts become due. Each Company confirms that
any charges which CITBC may so make to its Revolving Loan Account as herein
provided will be made as an accommodation to such Company and solely at CITBC's
discretion.

         4.8 In the event this Financing Agreement or the Line of Credit is
terminated by either CITBC or the Companies for any reason whatsoever, all Capex
Loans shall become due and payable on the effective date of such termination
notwithstanding any provision to the contrary in the Capex Promissory Notes or
this Financing Agreement.

SECTION 5.  LETTERS OF CREDIT

         In order to assist the Companies in establishing or opening standby
Letters of Credit with an Issuing Bank the Companies have requested CITBC to
join in the applications for such Letters of Credit, and/or guarantee payment or
performance of such Letters of Credit and any drafts or acceptances thereunder
through the issuance of the Letter of Credit Guaranties, thereby lending CITBC's
credit to the Companies, and CITBC has agreed to do so. These arrangements shall
be handled by CITBC subject to the terms and conditions set forth below.

         5.1 The amount, purpose and extent of the standby Letters of Credit and
changes or modifications thereof by the 


                                       41
<PAGE>   45
Companies and/or the Issuing Bank of the terms and conditions thereof shall in
all respects be subject to the prior approval of CITBC in the exercise of its
reasonable discretion; provided however, that: a) in no event may the aggregate
amount of all such outstanding standby Letters of Credit exceed, in the
aggregate, at any one time $8,000,000.00; b) the Letters of Credit and all
documentation in connection therewith shall be in form and substance reasonably
satisfactory to the Companies, CITBC and the Issuing Bank; c) the Letter of
Credit line of credit shall be deemed to be a subline within the Revolving Line
of Credit and all Letters of Credit shall be reserved dollar for dollar from
Northwest Pipe Availability or Thompson Pipe Availability, as applicable, as an
Availability Reserve; and (d) except to the extent provided in paragraph 5.9
below, CITBC shall not assist Thompson Steel in establishing or opening letters
of credit as set forth in this Section 5.

         5.2 CITBC shall have the right, without notice to the Companies, to
charge the applicable Company's account on CITBC's books with the amount of any
and all indebtedness, liability or obligation of any kind incurred by CITBC
under the Letter of Credit Guaranty at the earlier of a) payment by CITBC under
the Letter of Credit Guaranty, or b) the occurrence of an Event of Default. Any
amount charged to a Company's loan account shall be deemed a Revolving Loan
hereunder and shall incur interest at the rate provided in Section 8, paragraph
8.1 of this Financing Agreement.

         5.3 Each Company unconditionally indemnifies CITBC and holds CITBC
harmless from any and all loss, claim or liability incurred by CITBC arising
from any transactions or occurrences relating to Letters of Credit established
or opened for such Company's account, the collateral relating thereto and any
drafts or acceptances thereunder, and all Obligations thereunder, including any
such loss or claim due to any action taken by any Issuing Bank, other than for
any such loss, claim or liability arising out of the gross negligence or willful
misconduct by CITBC under the Letter of Credit Guaranty. Each Company further
agrees to hold CITBC harmless from any errors or omission, negligence or
misconduct by the Issuing Bank, provided however that, the foregoing shall not
be deemed to be a waiver of or otherwise limit such Company's rights with
respect to the 


                                       42
<PAGE>   46
Issuing Bank. Each Company's unconditional obligation to CITBC hereunder shall
not be modified or diminished for any reason or in any manner whatsoever, other
than as a result of CITBC's gross negligence or willful misconduct. Each Company
agrees that any charges incurred by CITBC for such Company's account by the
Issuing Bank shall be conclusive on CITBC and may be charged to such Company's
account.

         5.4 CITBC shall not be responsible for: the existence, character,
quality, quantity, condition, packing, value or delivery of the goods purporting
to be represented by any documents; any difference or variation in the
character, quality, quantity, condition, packing, value or delivery of the goods
from that expressed in the documents; the validity, sufficiency or genuineness
of any documents or of any endorsements thereon, even if such documents should
in fact prove to be in any or all respects invalid, insufficient, fraudulent or
forged; the time, place, manner or order in which shipment is made; partial or
incomplete shipment, or failure or omission to ship any or all of the goods
referred to in the Letters of Credit or documents; any deviation from
instructions; delay, default, or fraud by the shipper and/or anyone else in
connection with the Collateral or the shipping thereof; or any breach of
contract between the shipper or vendors and the Companies. Furthermore, without
being limited by the foregoing, CITBC shall not be responsible for any act or
omission with respect to or in connection with any Collateral imported pursuant
to any Letter of Credit.

         5.5 Each Company agrees that any action taken by CITBC, if taken in
good faith, or any action taken by any Issuing Bank, under or in connection with
the Letters of Credit, the guarantees, the drafts or acceptances, or the
Collateral, shall be binding on such Company and shall not put CITBC in any
resulting liability to such Company. In furtherance thereof, CITBC shall have
the full right and authority to clear and resolve any questions of
non-compliance of documents; to give any instructions as to acceptance or
rejection of any documents or goods; to execute any and all steamship or airways
guaranties (and applications therefore), indemnities or delivery orders; to
grant any extensions of the maturity of, time of payment for, or time of
presentation of, any drafts, acceptances, or documents; 



                                       43
<PAGE>   47
and to agree to any amendments, renewals, extensions, modifications, changes or
cancellations of any of the terms or conditions of any of the applications,
Letters of Credit, drafts or acceptances; all in CITBC's sole name, and the
Issuing Bank shall be entitled to comply with and honor any and all such
documents or instruments executed by or received solely from CITBC, all without
any notice to or any consent from the Companies.

         5.6 Without CITBC's express consent and endorsement in writing, each
Company agrees: a) not to execute any and all applications for steamship or
airway guaranties, indemnities or delivery orders; to grant any extensions of
the maturity of, time of payment for, or time of presentation of, any drafts,
acceptances or documents; or to agree to any amendments, renewals, extensions,
modifications, changes or cancellations of any of the terms or conditions of any
of the applications, Letters of Credit, drafts or acceptances; and b) after the
occurrence of an Event of Default which is not cured within any applicable grace
period, if any, or waived by CITBC, not to i) clear and resolve any questions of
non-compliance of documents, or ii) give any instructions as to acceptance or
rejection of any documents or goods.

         5.7 Each Company agrees that any necessary import, export or other
licenses or certificates for the import or handling of the Collateral will have
been promptly procured; all foreign and domestic governmental laws and
regulations in regard to the shipment and importation of the Collateral, or the
financing thereof will have been promptly and full complied with; and any
certificates in that regard that CITBC may at any time request will be promptly
furnished. In this connection, each Company warrants and represents that all
shipments of Inventory pursuant to Letters of Credit opened pursuant hereto and
made under any such Letters of Credit are in accordance with the laws and
regulations of the countries in which the shipments originate and terminate, and
are not prohibited by any such laws and regulations. Each Company assumes all
risk, liability and responsibility for, and agrees to pay and discharge, all
present and future local, state, federal or foreign taxes, duties, or levies.
Any embargo, restriction, laws, customs or regulations of any country, state,
city, or other political subdivision, 



                                       44
<PAGE>   48
where the Collateral is or may be located, or wherein payments are to be made,
or wherein drafts may be drawn, negotiated, accepted, or paid, shall be solely
the Companies' risk, liability and responsibility.

         5.8 Upon any payments made to the Issuing Bank under the Letter of
Credit Guaranty, CITBC shall acquire by subrogation, any rights, remedies,
duties or obligations granted or undertaken by the applicable Company to the
Issuing Bank in any application for Letters of Credit, any standing agreement
relating to Letters of Credit or otherwise, all of which shall be deemed to have
been granted to CITBC and apply in all respects to CITBC and shall be in
addition to any rights, remedies, duties or obligations contained herein.

         5.9 Thompson Steel has pledged certain assets in connection with the
issuance by the Kentucky Rural Economic Development Authority and the County of
Caldwell, Kentucky of Industrial Revenue Bonds having an aggregate original
principal value of $5,700,000 and $2,500,000, respectively (the "Bonds"). The
approximate outstanding balance owing to the holders of the Bonds on the date
hereof does not exceed $3,000,000. Congress Financial Corporation has issued
letters of credit for the account of Thompson Steel in connection with the
Bonds; and CITBC, concurrently herewith, has provided the Congress
Indemnification in favor of Congress Financial Corporation in the event draws
are made on such letters of credit. Northwest Pipe hereby agrees and confirms
that it shall be the primary obligation of Northwest Pipe, secured by the
Collateral pledged by Northwest Pipe hereunder, to pay to CITBC any amounts
required to be paid by CITBC based upon the Congress Indemnification, and
Northwest Pipe's Obligations therefor shall be jointly and severally guaranteed
by Thompson Pipe and Thompson Steel pursuant to Section 11 hereof. Thompson Pipe
and Thompson Steel hereby each agree and confirm that the Congress
Indemnification, and the undertaking of Northwest Pipe as described in this
paragraph 5.9, constitute valuable consideration to Thompson Pipe and Thompson
Steel, as they enhance the value of each such Companies thereby. Upon the sale
of any real or personal property assets pledged by Thompson Steel in connection
with the Bonds, the entire net proceeds of such sale be applied to the Bonds,
and any excess 



                                       45
<PAGE>   49
shall be applied to the Obligations in such order as CITBC shall reasonably
elect.

SECTION 6.  COLLATERAL

         6.1 As security for the prompt payment in full of all loans and
advances made and to be made to the Companies from time to time by CITBC
pursuant hereto, as well as to secure the payment in full of the other
Obligations, the Companies hereby jointly and severally pledge and grant to
CITBC a continuing general lien upon and security interest in all of the
following property and interests in property (collectively, "Collateral"):

         (a)    present and hereafter acquired Inventory;

         (b)    present and hereafter acquired Equipment;

         (c)    present and future Accounts;

         (d)    present and future Documents of Title;

         (e)    present and future General Intangibles;

         (f)    Real Estate;

         (g)    Stock Collateral; and

         (h)    the proceeds of any and all of the foregoing.

Notwithstanding the foregoing, the grant of security interest by Thompson Steel
in its Real Estate and Equipment located in Princeton, Kentucky shall become
effective when consents from the trustees for the holders of the Bonds referred
to in paragraph 7.9(a) of Section 7 hereof have been obtained.

         6.2 The security interests granted hereunder shall extend and attach
to:

         (a) All Collateral which is presently in existence and which is owned
by any Company or in which any Company has any interest, whether held by such
Company or others for its account, and, if any Collateral is Equipment, whether
such Company's 



                                       46
<PAGE>   50
interest in such Equipment is as owner or lessee or conditional vendee;

         (b) All Equipment whether the same constitutes personal property or
fixtures, including, but without limiting the generality of the foregoing, all
dies, jigs, tools, benches, tables, accretions, component parts thereof and
additions thereto, as well as all accessories, motors, engines and auxiliary
parts used in connection with or attached to the Equipment; and

         (c) All Inventory and any portion thereof which may be returned,
rejected, reclaimed or repossessed by either CITBC or any Company from such
Company's customers, as well as to all supplies, goods, incidentals, packaging
materials, labels and any other items which contribute to the finished goods or
products manufactured or processed by any Company, or to the sale, promotion or
shipment thereof.

         6.3 The Companies agree to safeguard, protect and hold all Inventory
for CITBC's account and make no disposition thereof, provided that the Companies
may sell and/or lease their Inventory in the ordinary course of the business of
the Companies as herein provided. Absent the occurrence of an Event of Default
and notice from CITBC to the Companies to the contrary, as provided for below,
any Inventory may be sold and shipped by the Companies to their customers in the
ordinary course of the Companies' business, on open account and on terms
currently being extended by the Companies to their customers, provided that all
proceeds of all sales (including cash, accounts receivable, checks, notes,
instruments for the payment of money and similar proceeds) are forthwith
transferred, endorsed, and turned over and delivered to CITBC in accordance with
paragraph 3.4 of Section 3 of this Financing Agreement. CITBC shall have the
right to withdraw this permission at any time upon the occurrence of an Event of
Default and until such time as such Event of Default is waived or cured to
CITBC's satisfaction, in which event no further disposition shall be made of the
Inventory by the Companies without CITBC's prior written approval. Cash sales or
sales of Inventory in which a lien upon, or security interest in, Inventory is
retained by the Companies (other than bill and hold sales and material man's
liens, as expressly permitted in 



                                       47
<PAGE>   51
this Financing Agreement) shall be made by the Companies only with the approval
of CITBC, and the proceeds of such sales or sales of inventory for cash shall
not be commingled with the Companies' other property, but shall be segregated,
held by the Companies in trust for CITBC as CITBC's exclusive property, and
shall be delivered immediately by the Companies to CITBC in the identical form
received by the Companies by deposit to the Depository Accounts. The Companies
shall not sell any of their Inventory on a consignment basis. Upon the sale,
exchange, or other disposition of Inventory, as herein provided, the security
interest in the Companies' Inventory provided for herein shall, without break in
continuity and without further formality or act, continue in, and attach to, all
proceeds, including any instruments for the payment of money, accounts
receivable, contract rights, documents of title, shipping documents, chattel
paper and all other cash and non-cash proceeds of such sale, exchange or
disposition. As to any such sale, exchange or other disposition, CITBC shall
have all of the rights of an unpaid seller, including stoppage in transit,
replevin, rescission and reclamation.

         6.4 The Companies agree at their own cost and expense to keep the
Equipment in as good and substantial repair and condition as the same is now or
at the time the lien and security interest granted herein shall attach thereto,
reasonable wear and tear excepted, making any and all repairs and replacements
when and where necessary. The Companies also agree to safeguard, protect and
hold all Equipment for CITBC's account and make no disposition thereof unless
the Companies first obtain the prior written approval of CITBC. Any sale,
exchange or other disposition of any Equipment shall only be made by the
Companies with the prior written approval of CITBC, and the proceeds of any such
sales shall not be commingled with the Companies' other property, but shall be
segregated, held by the Companies in trust for CITBC as CITBC's exclusive
property, and shall be delivered immediately by the Companies to CITBC in the
identical form received by the Companies by deposit to the Depository Accounts.
Upon the sale, exchange, or other disposition of the Equipment, as herein
provided, the security interest provided for herein shall, without break in
continuity and without further formality or act, continue in, and attach to, all
proceeds, including any instruments for the payment of money, accounts
receivable, 



                                       48
<PAGE>   52
contract rights, documents of title, shipping documents, chattel paper and all
other cash and non-cash proceeds of such sales, exchange or disposition. As to
any such sale, exchange or other disposition, CITBC shall have all of the rights
of an unpaid seller, including stoppage in transit, replevin, rescission and
reclamation. Notwithstanding anything hereinabove contained to the contrary, the
Companies may sell, exchange or otherwise dispose of obsolete Equipment or
Equipment no longer needed in the Companies' operations, provided, however, that
(a) the then book value of the Equipment so disposed of does not exceed $250,000
in the aggregate in any fiscal year and (b) the proceeds of such sales or
dispositions are delivered to CITBC in accordance with the foregoing provisions
of this paragraph, except that the Companies may retain and use such proceeds to
purchase forthwith replacement Equipment which the Companies determine in their
reasonable business judgment to have a collateral value at least equal to the
Equipment so disposed of or sold, provided, however, that the aforesaid right
shall automatically cease upon the occurrence of an Event of Default which is
not cured within any applicable grace period or waived.

         6.5 The rights and security interests granted to CITBC hereunder are to
continue in full force and effect, notwithstanding the termination of this
Financing Agreement or the fact that the accounts maintained in the Companies'
names on the books of CITBC may from time to time be temporarily in a credit
position, until the final payment in full to CITBC of all Obligations and the
termination of this Financing Agreement. Any delay or omission by CITBC to
exercise any right hereunder, shall not be deemed a waiver thereof, or be deemed
a waiver of any other right, unless such waiver shall be in writing and signed
by CITBC. A waiver on any one occasion shall not be construed as a bar to or
waiver of any right or remedy on any future occasion.

         6.6 To the extent that the Obligations are now or hereafter secured by
any assets or property other than the Collateral or by the guarantee,
endorsement, assets or property of any other person, then CITBC shall have the
right in its sole discretion to determine which rights, security, liens,
security interests or remedies CITBC shall at any time pursue, foreclose upon,
relinquish, subordinate, modify or take any other action 



                                       49
<PAGE>   53
with respect to, without in any way modifying or affecting any of them, or any
of CITBC's rights hereunder.

         6.7 Any reserves or balances to the credit of the Companies and any
other property or assets of the Companies in the possession of CITBC may be held
by CITBC as security for any Obligations and applied in whole or partial
satisfaction of such Obligations when due. The liens and security interests
granted herein and any other lien or security interest CITBC may have in any
other assets of the Companies, shall secure payment and performance of all now
existing and future Obligations. CITBC may in its discretion charge any or all
of the Obligations to the account of the Companies when due.

         6.8 This Financing Agreement and the obligation of the Companies to
perform all of their covenants and obligations hereunder are further secured by
a mortgage, deed of trust or assignment on the Real Estate.

         6.9 The Companies shall give to CITBC from time to time such mortgage,
deed of trust or assignment on the Real Estate or real estate acquired after the
date hereof as CITBC shall require to obtain a valid first lien (other than with
respect to CITBC's second lien on Northwest Pipe's Portland, Oregon facility and
Thompson Steel's Princeton, Kentucky facility) thereon subject only to those
exceptions of title as set forth in future title insurance policies that are
satisfactory to CITBC.

         6.10 The Companies shall give to CITBC, and/or shall cause the
appropriate party to give to CITBC, from time to time such pledge or security
agreements with respect to General Intangibles (now or hereafter acquired) of
the Companies as CITBC shall require to obtain valid first liens thereon.

         6.11 Without in any way limiting the right of CITBC to enforce rights
on behalf of the Companies as provided herein, the Companies shall diligently
pursue all rights, remedies, powers and privileges available to them under the
Stock Purchase Agreement.

SECTION 7.  REPRESENTATIONS, WARRANTIES AND COVENANTS

         7.1 Each Company hereby warrants and represents and/or covenants that:
i) the fair value of such Company's assets exceeds the book value of such
Company's liabilities; ii) such Company is generally able to pay its debts as
they become due and payable; and iii) such Company does not have unreasonably
small capital to carry on its business as it is currently conducted absent
extraordinary and unforeseen circumstances. Each Company further warrants and
represents that a) except for the Permitted Encumbrances, the security interests
granted herein constitute and shall at all times constitute the first and only
liens on the Collateral; b) after filing of financing statements in the
applicable filing clerk's office in the states listed on the Perfection

lien on the Collateral, that can be perfected by the filing of such financing
statements, except for the Permitted Encumbrances; c) except for the Permitted
Encumbrances, such Company is or will be at the time additional Collateral is
acquired by it, the absolute owner of the Collateral with full right to pledge,
sell, consign, transfer and create a security interest therein, free and clear
of any and all claims or liens in favor of others; d) such Company will at its
expense, until the Obligations are indefeasibly paid in full and CITBC shall
have no further commitment or obligation hereunder, warrant and, at CITBC's
request, defend the same from any and all claims and demands of any other person
other than the holders of the Permitted Encumbrances; e) such Company will not
grant, create or permit to exist, any lien upon or security interest in the
Collateral, or any proceeds thereof, in favor of any other person other than the
holders of the Permitted Encumbrances; f) the representations and warranties in
the Perfection Certificate are true and correct; g) the Equipment does not
comprise a part of the Inventory of such Company and that the Equipment is and
will only be used by such Company in its business and will not be held for sale

premises, or otherwise disposed of by such Company without the prior written
approval of CITBC except as otherwise permitted in paragraph 6.4 of Section 6 of
this Financing Agreement; (h) Schedule 1 hereto contains an accurate and
complete list as of the date hereof of all Inventory locations of the Companies;
(i) Schedule 2 hereto contains an 



                                       51
<PAGE>   55
accurate and complete list as of the date hereof of all trade names used by the
Companies; and (j) Schedule 3 hereto contains an accurate and complete list as
of the date hereof of all patents, trademarks and copyrights of the Companies.

         7.2 Each Company agrees to maintain books and records pertaining to the
Collateral in such detail, form and scope as CITBC shall reasonably require.
Each Company agrees that CITBC or its agents may enter upon such Company's
premises at any time during normal business hours, and from time to time, for
the purpose of inspecting the Collateral, and any and all records pertaining
thereto. Each Company agrees to afford CITBC thirty (30) days prior written
notice of any change in the location of any Collateral, other than to locations,
that as of the date hereof, are known to CITBC and at which CITBC has filed
financing statements and otherwise fully perfected its liens thereon. The
Companies are also to advise CITBC promptly, in sufficient detail, of any
material adverse change relating to the type, quantity or quality of the
Collateral or on the security interests granted to CITBC therein.

         7.3 Each Company agrees to: execute and deliver to CITBC, from time to
time, solely for CITBC's convenience in maintaining a record of the Collateral,
such written statements, and schedules as CITBC may reasonably require,
designating, identifying or describing the Collateral pledged to CITBC
hereunder. Any Company's failure, however, to promptly give CITBC such
statements, or schedules shall not affect, diminish, modify or otherwise limit
CITBC's security interests in the Collateral.

         7.4 Each Company agrees to comply with the requirements of all state
and federal laws in order to grant to CITBC valid and perfected first security
interests in the Collateral (except as otherwise provided herein) subject only
to the Permitted Encumbrances. CITBC is hereby authorized by the Companies to
file any financing statements covering the Collateral whether or not any
Company's signature appears thereon. The Companies agree to do whatever CITBC
may reasonably request, from time to time, by way of: searching records, filing
notices of liens, financing statements, amendments, renewals and continuations
thereof; cooperating with CITBC's custodians; 



                                       52
<PAGE>   56
keeping stock records; transferring proceeds of Collateral to CITBC's
possession; and performing such further acts as CITBC may reasonably require in
order to effect the purposes of this Financing Agreement.

         7.5 (a) The Companies agree to maintain insurance on the Real Estate,
Equipment and Inventory (wherever located) under such policies of insurance,
with such insurance companies, in such reasonable amounts and covering such
insurable risks as are at all times reasonably satisfactory to CITBC. All
policies covering the Real Estate, Equipment and Inventory are, subject to the
rights of any holders of Permitted Encumbrances holding claims senior to CITBC,
to be made payable to CITBC, in case of loss, under a standard non-contributory
"mortgagee", "lender" or "secured party" clause and are to contain such other
provisions as CITBC may require to fully protect CITBC's interest in the Real
Estate, Inventory and Equipment and to any payments to be made under such
policies. All original policies or true copies thereof are to be delivered to
CITBC, the premium paid when due and in the ordinary course of business, with
the loss payable endorsement in CITBC's favor, and shall provide for not less
than thirty (30) days' prior written notice to CITBC of the exercise of any
right of cancellation. At the Companies' request, or if the Companies fail to
maintain such insurance, CITBC may arrange for such insurance, but at the
Companies' expense and without any responsibility on CITBC's part for: obtaining
the insurance, the solvency of the insurance companies, the adequacy of the
coverage, or the collection of claims. Upon the occurrence of an Event of
Default which is not waived or cured to CITBC's satisfaction, CITBC shall,
subject to the rights of any holders of Permitted Encumbrances holding claims
senior to CITBC, have the sole right, in the name of CITBC or any Company, to
file claims under any insurance policies, to receive, receipt and give
acquittance for any payments that may be payable thereunder, and to execute any
and all endorsements, receipts, releases, assignments, reassignments or other
documents that may be necessary to effect the collection, compromise or
settlement of any claims under any such insurance policies.

         (b)    (i) In the event of any loss or damage by fire or other
                casualty, insurance proceeds relating to 



                                       53
<PAGE>   57
                Inventory shall first reduce the applicable Company's Revolving
                Loan, then such Company's Capex Loans.

         ii)    In the event any part of the Companies' Real Estate or Equipment
                is damaged by fire or other casualty and the insurance proceeds
                for such damage or other casualty (the "Proceeds") is less than
                or equal to $100,000.00, CITBC shall promptly apply such
                Proceeds to reduce the applicable Company's outstanding balances
                under the Revolving Loan account or, if there is no balance, to
                such Obligations as CITBC may reasonably elect.

         iii)   As long as x) an Event of Default has not occurred (which is not
                cured to CITBC's satisfaction), y) the Companies have sufficient
                business interruption insurance to replace the lost profits of
                any of the Companies' facilities, and z) the Proceeds are in
                excess of $100,000.00, the Companies may elect (by delivering
                written notice to CITBC) to replace, repair or restore such Real
                Estate or Equipment to substantially the equivalent condition
                prior to such fire or other casualty as set forth herein. If the
                Companies do not, or cannot, elect to use the Proceeds as set
                forth above, CITBC may, subject to the rights of any holders of
                Permitted Encumbrances holding claims senior to CITBC, apply the
                Proceeds to the payment of the Obligations in such manner and in
                such order as CITBC may reasonably elect.

         iv)    If a Company elects to use the Proceeds for the repair,
                replacement or restoration of any Real Estate or Equipment, and
                there is then no Event of Default, i) proceeds of insurance on
                Equipment and Real Estate in excess of $100,000.00 will be
                applied to the reduction of the Revolving Loans of such Company
                and ii) CITBC may set up a reserve against Availability for an
                amount equal to the proceeds referred to in clause i) hereof.
                The reserve will be reduced dollar-for-dollar upon receipt of
                non-cancelable executed purchase orders, delivery receipts or
                contracts for the replacement, repair or 


                                       54
<PAGE>   58
                restoration of Equipment or the Real Estate and disbursements in
                connection therewith. Prior to the commencement of any
                restoration, repair or replacement of Real Estate, such Company
                shall provide CITBC with a restoration plan and a total budget
                certified by an independent third party experienced in
                construction costing. If there are insufficient Proceeds to
                cover the cost of restoration as so determined, such Company
                shall be responsible for the amount of any such insufficiency,
                prior to the commencement of restoration and shall demonstrate
                evidence of such before the reserve will be reduced. Completion
                of restoration shall be evidenced by a final, unqualified
                certification of the design architect employed, if any; an
                unconditional Certificate of Occupancy, if applicable; such
                other certification as may be required by law; or if none of the
                above is applicable, a written good faith determination of
                completion by such Company (herein collectively the
                "Completion"). Upon Completion, any remaining reserve as
                established hereunder will be automatically released.

         (v)    The Companies agree to pay any reasonable costs, fees or
                expenses which CITBC may reasonably incur in connection with
                this paragraph 7.5.

         7.6 The Companies agree to pay, when due, all taxes, assessments,
claims and other charges (herein "taxes") lawfully levied or assessed upon the
Companies or the Collateral and if such taxes remain unpaid after the date fixed
for the payment thereof unless: (i) such taxes are being diligently contested in
good faith by the Companies by appropriate proceedings, (ii) the Companies
establish such reserves as may be required by GAAP or, in the alternative or in
addition thereto, CITBC establishes an Availability Reserve in such amount as
CITBC may determined in its reasonable discretion, or (iii) if any lien shall be
claimed thereunder x) for taxes due the United States of America or any state
thereof having similar tax priority status, or y) which in CITBC's opinion might
create a valid obligation having priority over the rights granted to CITBC
herein, CITBC may, on the 


                                       55
<PAGE>   59
Companies' behalf, pay such taxes, and the amount thereof shall be an Obligation
secured hereby and due to CITBC on demand.

         7.7 Each Company: (a) agrees to comply with all acts, rules,
regulations and orders of any legislative, administrative or judicial body or
official, which the failure to comply with would have a material and adverse
impact on the Collateral, or any material part thereof, or on the operation of
such Company's business; provided that such Company may contest any acts, rules,
regulations, orders and directions of such bodies or officials in any reasonable
manner which will not, in CITBC's reasonable opinion, materially and adversely
effect CITBC's rights or priority in the Collateral; (b) agrees to comply with
all environmental statutes, acts, rules, regulations or orders as presently
existing or as adopted or amended in the future applicable to the ownership
and/or use of its real property and operation of its business which the failure
to comply with would have a material and adverse impact on the Collateral, or
any material part thereof, or on the operation of the business of such Company.
Each Company hereby indemnifies CITBC and agrees to defend and hold CITBC
harmless from and against any and all loss, damage, claim, liability, injury or
expense which CITBC may sustain or incur (other than solely as a result of the
physical actions of CITBC on the Companies' premises) in connection with: any
claim or expense asserted against CITBC as a result of any environmental
pollution, hazardous material or environmental clean-up of the Companies' real
property; or any claim or expense which results from the Companies' operations
(including, but not limited to, the Companies' off-site disposal practices); any
claim or expense relating to the Companies' Inventory and/or Equipment, and the
Companies further agree that this indemnification shall survive termination of
this Financing Agreement as well as the payment of all Obligations or amounts
payable hereunder; and (c) shall not be deemed to have breached any provision of
this paragraph 7.7 if (i) the failure to comply with the requirements of this
paragraph 7.7 resulted from good faith error or innocent omission, (ii) the
Companies promptly commence and diligently pursue a cure of such breach, (iii)
such failure is cured within fifteen (15) Business Days following the Companies'
receipt of notice of such failure, and (iv) such failure has not resulted in a
material adverse effect on the business, financial condition or operations of
the 

                                       56
<PAGE>   60
Companies or on the Collateral. Upon receipt by the Companies of any notice of
non-compliance with any applicable environmental rules or regulation, of any
required expenditures for compliance, any spill or omission or other regulated
"event", or any claim resulting from the Companies' business or practices or
relating to the Collateral, the Companies shall establish such reserves as may
be required by GAAP or, in the alternative or in addition thereto, CITBC may
establish an Availability Reserve in such amount as CITBC may require in its
reasonable discretion.

         7.8 Until termination of the Financing Agreement and payment and
satisfaction of all Obligations due hereunder, the Companies agree that, unless
CITBC shall have otherwise consented in writing, the Companies will furnish to
CITBC: (a) within ninety (90) days after the end of each fiscal year of
Northwest Pipe, an audited Consolidated Balance Sheet and an audited
Consolidating Balance Sheet as at the close of such year, and statements of
profit and loss, cash flow and reconciliation of surplus of the Companies and
their subsidiaries for such year, audited by independent public accountants
selected by the Companies and satisfactory to CITBC in the exercise of its
reasonable business judgement; (b) within forty-five (45) days after the end of
each fiscal quarter of Northwest Pipe, a Consolidating Balance Sheet as at the
end of such period and statements of profit and loss, cash flow and surplus of
the Companies and their subsidiaries for such period, certified by an authorized
financial or accounting officer of Northwest Pipe; (c) within thirty (30) days
after the end of each month, a Consolidated Balance Sheet as at the end of such
period and statements of profit and loss, cash flow and surplus of the Companies
and their subsidiaries for such period, certified by an authorized financial or
accounting officer of Northwest Pipe; and (d) from time to time, such further
information regarding the business affairs and financial condition of the
Companies as CITBC may reasonably request, including without limitation annual
cash flow projections in form satisfactory to CITBC. Each financial statement
which the Companies are required to submit hereunder must be accompanied by an
officer's certificate, signed by the President, Vice President, Controller, or
Treasurer of Northwest Pipe, pursuant to which any one such officer must certify
that: (i) the financial statement(s) fairly and accurately represent(s) the
Companies' financial condition at the

                                       57
<PAGE>   61
end of the particular accounting period, as well as the Companies' operating
results during such accounting period, subject to year-end audit adjustments;
(ii) during the particular accounting period: (x) there has been no Default or
Event of Default under this Financing Agreement, provided, however, that if any
such officer has knowledge that any such Default or Event of Default, has
occurred during such period, the existence of and a detailed description of same
shall be set forth in such officer's certificate; and (y) no Company has
received any notice of cancellation with respect to its property insurance
policies; and (iii) the exhibits attached to such financial statement(s)
constitute detailed calculations showing compliance with all financial covenants
contained in this Financing Agreement.

         7.9 The Companies shall cause each of the following to occur to CITBC's
reasonable satisfaction:

         a) The Companies shall use their best efforts to obtain within thirty
(30) days after the Closing Date consents from the trustees for the holders of
the Bonds necessary to permit Thompson Steel to grant in favor of CITBC a lien
of not less than second priority on the Real Estate and Equipment of Thompson
Steel located in Princeton, Kentucky; and Thompson Steel shall, promptly after
receipt of such consents, execute and deliver to CITBC such mortgages, deeds of
trust and other documentation as CITBC may reasonably require to obtain a
perfected lien of not less than second priority on such Real Estate and
Equipment. The failure of Thompson Steel to obtain such consents and validly
grant such liens within ninety (90) days of the Closing Date shall constitute an
Event of Default hereunder.

         b) Within thirty (30) days after the Closing Date, Thompson Pipe shall
have executed and delivered to CITBC such mortgages and deeds of trust as CITBC
may reasonably require to obtain a first lien on the Real Estate owned by
Thompson Pipe in Denver, Colorado.

         c) Within ninety (90) days after the Closing Date, CITBC shall have
received, in respect of the mortgage or deed of trust required by clause a)
above, a mortgagee's title policy or marked-up unconditional binder for such
insurance. Within thirty 

                                       58
<PAGE>   62
(30) days after the Closing Date, CITBC shall have received, in respect of the
mortgage or deed of trust required by clause b) above, a mortgagee's title
policy or marked-up unconditional binder for such insurance. Each such policy
shall (i) be in the amount of $4,100,000 on the Denver, Colorado Real Estate,
and $2,400,000 on the Princeton, Kentucky Real Estate; (ii) insure that the
mortgage or deed of trust insured thereby creates a valid first lien on the
property covered by such mortgage or deed of trust (other than with respect to
CITBC's second lien on Thompson Steel's Princeton, Kentucky facility), free and
clear of all defects and encumbrances except those acceptable to CITBC; (iii)
name CITBC as the insured thereunder; and (iv) contain such endorsements and
effective coverage as CITBC may reasonably request, including without limitation
the revolving line of credit endorsement. CITBC shall also have received
evidence that all premiums in respect of such policies have been paid and that
all charges for mortgage recording taxes, if any, shall have been paid.

         d) Within thirty (30) days after the Closing Date, CITBC and the title
insurance company issuing each policy referred to in the immediately preceding
paragraph (each, a "Title Insurance Company") shall have received maps or plats
of a perimeter or boundary of the site of each of the properties covered by the
mortgages or deeds of trust, dated a date satisfactory to CITBC and the relevant
Title Insurance Company and either: (a) prepared by an independent professional
licensed land surveyor satisfactory to CITBC and the relevant Title Insurance
Company, which maps or plats and the surveys on which they are based shall be
made in accordance with the Minimum Standard Detail Requirements for Land Title
Surveys jointly established and adopted by the American Land Title Association
and the American Congress on Surveying and Mapping; and, without limiting the
generality of the foregoing, there shall be surveyed and shown on the maps or
plats or surveys the following: (i) the locations on such sites of all the
buildings, structures and other improvements and the established building
setback lines insofar as the foregoing affect the perimeter or boundary of such
property; (ii) the lines of streets abutting the sites and width thereof; (iii)
all access and other easements appurtenant to the sites or necessary or
desirable to use the sites; (iv) all roadways, paths, driveways, easements,
encroachments and 



                                       59
<PAGE>   63
overhanging projections and similar encumbrances affecting the sites, whether
recorded, apparent from a physical inspection of the sites or otherwise known to
the surveyor; (v) any encroachments on any adjoining property by the building
structures and improvements on the sites; and (vi) if the site is designated as
being on a filed map, a legend relating the survey to said map. Further, the
survey shall A) be certified to CITBC and the Title Insurance Company and B)
contain a legend reciting as to whether or not the site is located in a flood
zone; or (b) the title report and policy for any such Real Estate shall omit any
title exception for surveys, in form and substance satisfactory to CITBC and its
counsel.

         e) Within thirty (30) days after the Closing Date, Thompson Pipe shall
enter into one or more lock box agreement(s) in form and substance acceptable to
CITBC in its reasonable business judgment.

         f) Within sixty (60) days after the Closing Date, the Companies shall
have prepared and delivered to CITBC (i) consolidating cash budget projections
for the Companies for the next consecutive twelve month period commencing on the
Closing Date, and (ii) the consolidating opening balance sheet of the Companies
as of the Closing Date, all of which shall be in form and substance satisfactory
to CITBC.

         7.10 Until termination of the Financing Agreement and payment and
satisfaction of all Obligations due hereunder, each Company agrees that, without
the prior written consent of CITBC (which consent shall be subject to its
reasonable business judgement), except as otherwise herein provided, such
Company will not:

         a)     Mortgage, assign, pledge, transfer or otherwise permit any lien,
                charge, security interest, encumbrance or judgment, (whether as
                a result of a purchase money or title retention transaction, or
                other security interest, or otherwise) to exist on any of its
                assets or goods, whether real, personal or mixed, whether now
                owned or hereafter acquired, except for the Permitted
                Encumbrances;


                                       60
<PAGE>   64
         b)     Incur or create any Indebtedness other than the Permitted
                Indebtedness;

         c)     Borrow any money on the security of such Company's Collateral
                from sources other than CITBC, except for Permitted
                Indebtedness;

         d)     Sell, lease, assign, transfer or otherwise dispose of i)
                Collateral, except the Equipment and Real Estate of Thompson
                Steel held for sale, or as otherwise specifically permitted by
                this Financing Agreement, or ii) either all or substantially all
                of such Company's assets, which do not constitute Collateral;

         e)     Merge, consolidate or otherwise alter or modify its corporate
                name, principal place of business, structure, status or
                existence, or enter into or engage in any operation or activity
                materially different from that presently being conducted by such
                Company;

         f)     Assume, guarantee, endorse, or otherwise become liable upon the
                obligations of any person, firm, entity or corporation, except
                by the endorsement of negotiable instruments for deposit or
                collection or similar transactions in the ordinary course of
                business;

         g)     Declare or pay any dividend of any kind on, or purchase,
                acquire, redeem or retire, any of the capital stock or equity
                interest, of any class whatsoever, whether now or hereafter
                outstanding, except that Northwest Pipe may redeem capital stock
                in an amount up to $3,000,000 in the aggregate if i) the
                Companies are not then in breach or violation of this Financing
                Agreement; ii) after giving effect to such redemption, no
                Default or Event of Default will have occurred hereunder; iii)
                all of the Companies' accounts payable are current in accordance

<PAGE>   65
                and iv) on the date of any such redemption, after giving effect
                to such redemption and all outstanding Revolving Loans, Letters
                of Credit, and any and all other extensions of credit to be made
                by CITBC to the Companies on such date, the Companies shall have
                a minimum additional Availability of at least $2,000,000.00;

         h)     Make any advance or loan to, or any investment in, any firm,

                being delivered pursuant to paragraph 7.9(f)(ii) hereof,

                on such opening balance sheet, and (ii) Thompson Pipe may (a)
                repay the loans held by Northwest Pipe to Thompson Pipe
                indicated on such opening balance sheet up to an aggregate
                amount not to exceed $1,800,000 (and to the extent such balance
                sheet reflects intercompany loans of less than $1,800,000,
                Thompson Pipe may make loans to Northwest Pipe), and (b) repay
                loans made after the Closing Date by Northwest Pipe to Thompson
                Pipe as permitted in clause (i), above; provided further,
                however, that each officer's certificate delivered pursuant 
                to paragraph 7.8 of Section 7 hereof shall indicate the amount

expenditures (actual or anticipated) in excess of $100,000.00 for x)
environmental clean-up, y) environmental compliance or z) environmental testing
and the impact of said expenses on the Companies' Working Capital; b) any
notices the Companies receive from any local, state or federal authority
advising the Companies of any environmental liability (real or potential)
stemming from a Company's operations, its premises, its waste disposal

copies of all such notices if so required; and c) each Company hereby represents
and warrants that, as of the Closing Date, it has not received notice of any
material violation of any applicable environmental rules and regulations,
including without limitation pursuant to CERCLA, any 



                                       63
<PAGE>   67
other "super-fund" laws or regulations and/or notice that such Company is a
"PRP" in any pending action or investigation.

         7.18 Without the prior written consent of CITBC, each Company agrees
that it will not enter into any transaction, including, without limitation, any
purchase, sale, lease, loan or exchange of property with any subsidiary or
affiliate of any Company, except as specifically provided in paragraph 7.10(h).

         7.19 The Companies shall: a) upon the acquisition after the date hereof
by the Companies of any Stock Collateral, promptly either (x) transfer and
deliver to CITBC all such Stock Collateral (together with the certificates
representing such Stock Collateral securities duly endorsed in blank or
accompanied by undated stock powers duly executed in blank) or (y) take such
other action as CITBC shall deem necessary or appropriate to perfect, and
establish the priority of, the liens granted by this Financing Agreement in such
Stock Collateral; and

         b) give, execute, deliver, file or record any and all financing
statements, notices, contracts, agreements or other instruments, obtain any and
all governmental approvals or consents and take any and all steps that may be
necessary or as CITBC may request to create, perfect, establish the priority of,
or to preserve the validity, perfection or priority of, the liens granted by
this Financing Agreement or to enable CITBC to exercise and enforce its rights,
remedies, powers and privileges under this Financing Agreement with respect to
such liens, including causing any or all of the Stock Collateral to be
transferred of record into the name of CITBC or its nominee (and CITBC agrees
that if any Stock Collateral is transferred into its name or the name of its
nominee, CITBC will thereafter promptly give to the pledging Company copies of
any notices and communications received by it with respect to the Stock
Collateral pledged by such Company).

         c) (i) cause the Stock Collateral to constitute at all times 100% of
the total number of shares of each class of capital stock of Thompson Pipe and
Thompson Steel then outstanding, (ii) cause all such shares to be duly
authorized, validly issued, fully paid and nonassessable and to be free of any
contractual restriction or any restriction under the charter or bylaws of 



                                       64
<PAGE>   68
this issuer of such Stock Collateral, upon the transfer of such Stock
Collateral.

         7.20 So long as CITBC has not given notice to Northwest Pipe and
Thompson Pipe of CITBC's intention to exercise voting rights regarding the Stock
Collateral after the occurrence of an Event of Default, each Company shall have
the right to exercise all voting, consensual and other powers of ownership
pertaining to the Stock Collateral pledged by it, for all purposes not
inconsistent with the terms of any Loan Document, provided that each Company
agrees that it will not vote the Stock Collateral in any manner that is
inconsistent with the terms of any Loan Document; and CITBC shall, at the
Companies' expense, execute and deliver to the Companies or cause to be executed
and delivered to the Companies all such proxies, powers of attorney, dividend
and other orders and other instruments, without recourse, as the Companies may
reasonably request for the purpose of enabling the Companies to exercise the
rights and powers which they are entitled to exercise pursuant to this Section
7.20.

         7.21 So long as no Event of Default shall have occurred and be
continuing, each Company shall be entitled to receive and retain any dividends
paid in cash out of earned surplus on the Stock Collateral pledged by it.

         7.22 If an Event of Default shall have occurred and be continuing, and
whether or not CITBC exercises any available right to declare any of the
Obligations due and payable, or seeks or pursues any other right, remedy, power
or privilege available to it under applicable law, this Financing Agreement or
any other Loan Document, all dividends and other distributions on the Stock
Collateral shall be paid directly to CITBC and retained by it as part of the
Stock Collateral, subject to the terms of this Financing Agreement, and, if
CITBC shall so request, the Companies agree to execute and deliver to CITBC
appropriate additional dividend, distribution and other orders and instruments
to that end. Thompson Pipe and Thompson Steel acknowledge their obligations
hereunder and shall, during the continuance of an Event of Default, pay all
dividends and other distributions on the Stock Collateral directly to CITBC as
set forth above.



                                       65
<PAGE>   69
         7.23 If an Event of Default shall have occurred and be continuing and
CITBC shall have given notice to Northwest Pipe and Thompson Pipe of CITBC's
intention to exercise voting rights regarding the Stock Collateral, CITBC shall
have the right, to the maximum extent permitted by law, to exercise all voting,
consensual and other powers of ownership pertaining to the Stock Collateral as
if CITBC were the sole and absolute owner of the Stock Collateral (and the
Companies agree to take all such action as may be appropriate to give effect to
such right).

         7.24 No reference in this Financing Agreement to proceeds or to the
sale or other disposition of Stock Collateral shall authorize the Companies to
sell or otherwise dispose of any Stock Collateral.

         7.25 The Companies represent and warrant that:

         a) The Pledged Stock evidenced by the certificates identified on
Schedule 6 is duly authorized, validly existing, fully paid and nonassessable,
and none of such Pledged Stock is subject to any contractual restriction, or any
restriction under the charter or by-laws of the issuer of such Pledged Stock,
upon the transfer of such Pledged Stock.

         b) The Pledged Stock evidenced by the certificates identified Schedule
6 constitutes (i) all of the issued and outstanding shares of capital stock of
any class of Thompson Steel beneficially owned by Thompson Pipe or any other
person, and (ii) all of the issued and outstanding shares of capital stock of
any class of Thompson Pipe beneficially owned by Northwest Pipe or any other
person; and Schedule 6 correctly identifies the respective class and par value
of the shares comprising such Pledged Stock and the respective number (and
registered owners) of the shares evidenced by each such certificate.


SECTION 8.  INTEREST, FEES AND EXPENSES

         8.1 The Revolving Loans shall bear a variable rate of interest, as
further described below, to be selected by the Companies in an irrevocable
written or facsimile notice 


                                       66
<PAGE>   70
("Revolving Loan Notice of Borrowing") effective upon receipt by CITBC, and
given no later than 2:00 p.m. (New York City time) on a) in the case of Chemical
Rate Loans, the date such borrowings are to be made and b) in the case of Libor
Loans, the fourth (4th) Business Day prior to the date such borrowings are to be
made. In the event a Company fails to timely select a variable interest rate,
the Revolving Loans shall be deemed Chemical Rate Loans until such Company
elects otherwise as herein provided. The Companies may elect either a) the
Chemical Bank Rate; b) the Libor Rate; or c) a combination of the Chemical Bank
Rate and the Libor Rate to be applied to different tranches of the Revolving
Loans.

         x)     In the event a Company elects the Chemical Bank Rate for all or
                any part of its Revolving Loans, the Revolving Loan Notice of
                Borrowing shall specify the amount of such loan. Interest
                thereon shall be computed based on the Chemical Bank Rate plus
                the Revolving Loans Chemical Rate Margin per annum. In the event
                of any change in the Chemical Bank Rate, the interest rate with
                respect to a Revolving Loan that is a Chemical Rate Loan shall
                change, as of the first of the month following any change, so as
                to remain an amount equal to the Revolving Loans Chemical Rate
                Margin above the Chemical Bank Rate.

         y)     In the event a Company initially elects the Libor Rate for all
                or any part of its Revolving Loans, the Revolving Loan Notice of
                Borrowing shall specify a) the amount of such loan and b) the
                initial Libor Period applicable thereto. Interest thereon shall
                be computed based on i) the applicable Libor Rate for such Libor
                Period plus the Revolving Loans Libor Margin.

         8.2. Each Capex Loan(s) shall bear interest at a variable interest
rate, as further described below, to be selected by the Companies in an
irrevocable written or facsimile notice ("Capex Loan Notice of Borrowing"),
effective upon receipt by CITBC, and given no later than 2:00 P.M. (New York
City Time) on a) in the case of Chemical Rate Loans, the date such 

                                       67
<PAGE>   71
borrowings are to be made and b) in the case of Libor Loans, the fourth (4th)
Business Day prior to the date such borrowings are to be made. In the event a
Company fails to select a variable interest rate, the Capex Loan shall be deemed
a Chemical Rate Loan until such Company elects otherwise as herein provided. In
the event that a Company elects a variable rate of interest on a Capex Loan,
such Company may further elect a) the Chemical Bank Rate; b) the Libor Rate; or
c) a combination of the Chemical Bank Rate and the Libor Rate to be applied to
different tranches of the Capex Loans.

         x)     In the event a Company elects the Chemical Bank Rate for all or
                any part of a Capex Loan, the Capex Loan Notice of Borrowing
                shall specify the amount of such loan. Interest thereon shall be
                computed based on the Chemical Bank Rate plus the Capex Loan
                Chemical Rate Margin per annum. In the event of any change in
                the Chemical Bank Rate, the interest rate with respect to a
                Capex Loan that is a Chemical Rate Loan shall change, as of the
                first of the month following any change, so as to remain an
                amount equal to the Capex Loan Chemical Rate Margin above the
                Chemical Bank Rate.

         y)     In the event a Company elects the Libor Rate for all or any part
                of a Capex Loan, the Capex Loan Notice of Borrowing shall
                specify a) the amount of such loan and b) the initial Libor
                Period applicable thereto. Interest thereon shall be computed
                based on the applicable Libor Rate for such Libor Period plus
                the Capex Loan Libor Margin.

         8.3 Provided that x) there is then no Default or Event of Default and
y) the applicable Company has given an irrevocable written or facsimile Notice
of Variable Interest Rate Conversion/Continuation (as described below) in
accordance with the provisions of this paragraph 8.3, such Company may I)
continue an outstanding Libor Loan for a subsequent Libor Period it selects
and/or II) convert all or any part of any outstanding variable interest rate on
the Revolving Loans and/or Capex Loans 



                                       68
<PAGE>   72
i) from a Chemical Bank Rate to a Libor Rate and/or ii) from a Libor Rate to a
Chemical Bank Rate, provided any such conversion is made in an integral multiple
of $100,000. Whenever a Company desires to either convert a variable interest
rate or to continue a Libor Rate for a subsequent Libor Period, such Company
must advise CITBC of its irrevocable election no later than a) four (4) Business
Days preceding the first day of the Libor Period if the conversion is from a
Chemical Bank Rate to a Libor Rate and b) one (1) Business Day prior to the end
of the then current Libor Period if the conversion is from a Libor Rate to a
Chemical Bank Rate. If no such election is timely made or can be made, CITBC
shall use the Chemical Bank Rate plus the appropriate Chemical Rate Margin to
compute any variable interest rate hereunder. Each written or facsimile Notice
of Variable Interest Rate Conversion/Continuation shall i) identify the loans to
be converted or continued, the aggregate outstanding principal balance thereof
and, in the case of Libor Loans to be continued, the last day of the Libor
Period therefor, (ii) specify the effective date of such conversion or
continuation provided, however, if the loans to be continued or converted are
Libor Loans, such continuation or conversion shall be effective only on the last
day of the then current Libor Period applicable to such loans (subject to
subparagraph (c) below of this paragraph 8.3), and (iii) specify the Libor
Period to be applicable to such converted or continued Libor Loan.

         a)     If a Company elects under this paragraph to either continue an
                outstanding Libor Loan for a subsequent Libor Period or convert
                all or any part of a Chemical Rate Loan to a Libor Loan, the
                interest thereon shall be computed based on the applicable Libor
                for such succeeding Libor Period plus the applicable Libor
                Margin.

         b)     If a Company elects under this paragraph to convert all or any
                part of a Libor Loan to a Chemical Rate Loan, the interest rate
                thereon shall be computed based on the Chemical Bank Rate plus
                the applicable Chemical Rate Margin.

                           c)       If the last day of a current Libor Period
                                    with respect to a loan that is to be
                                    continued as or converted to a Libor Loan
                                    under this paragraph is not a Business Day,
                                    then i) such continuation or conversion
                                    shall be made on the next succeeding
                                    Business Day and ii) during the period from
                                    such last day of the current Libor Period to
                                    such next succeeding Business Day, such loan
                                    shall bear interest as if it were a Chemical
                                    Rate Loan.

                           d)       Any Libor Period pertaining to a Libor Loan
                                    that begins on the last Business Day of a
                                    calendar month (or on a day for which there
                                    is no numerically corresponding day in the
                                    calendar month at the end of such Libor
                                    Period) shall end on the last Business Day
                                    of the calendar month at the end of such
                                    Libor Period.

                           e)       No Libor Period shall end after the
                                    scheduled maturity of this Financing
                                    Agreement or any subsequent Anniversary Date
                                    as to which the Companies or CITBC have the
                                    right to terminate the Line of Credit or
                                    this Financing Agreement by giving timely
                                    notice pursuant to Section 12 hereof.

                    8.4 Any charges, fees, commissions, costs and expenses
charged to CITBC for the Companies' account by any Issuing Bank in connection
with or arising out of Letters of Credit issued pursuant to this Financing
Agreement or out of transactions relating thereto will be charged to the
Companies' account in full when charged to or paid by CITBC and when made by any
such Issuing Bank shall be conclusive on CITBC.

                    8.5 The Companies shall reimburse or pay CITBC, as the case
may be, for: i) all Out-of-Pocket Expenses of CITBC and b) any applicable
Documentation Fee.

                    8.6 Upon the last Business Day of each month, commencing
immediately, the Companies shall pay CITBC the Line of Credit Fee.

                    8.7 Intentionally Omitted.

                    8.8 On April 30 of each year, commencing April 30, 1997, the
Companies shall pay to CITBC the Collateral Management Fee; provided, however,
that such fee shall not be payable on the scheduled termination date of this
Financing Agreement or any year thereafter if on such date (or within five (5)
days thereafter, provided timely notice of termination on such date was given)
this Financing Agreement is terminated in accordance with its terms, CITBC has
no further commitment or obligation hereunder, and all Obligations are paid in
full. The Collateral Management Fee shall be deemed earned when due and once
paid is non-refundable.

                    8.9 The Companies shall pay CITBC's standard charges for,
and the fees and expenses of, the CITBC personnel used by CITBC for reviewing
the books and records of the Companies and for verifying, testing protecting,
safeguarding, preserving or disposing of all or any part of the Collateral;
provided, however, that the foregoing shall not be payable until the occurrence
of an Event of Default if the Companies are paying a Collateral Management Fee.

                    8.10 The Companies hereby authorize CITBC to charge the
Companies' accounts with CITBC with the amount of all payments due hereunder as
such payments become due. The Companies confirm that any charges which CITBC may
so make to the Companies' accounts as herein provided will be made as an
accommodation to the Companies and solely at CITBC's discretion.

                    8.11 In consideration of the Letter of Credit Guaranties of
CITBC, the Companies shall pay CITBC the Letter of Credit Guaranty Fee which
shall be an amount equal to three-quarters of one percent (3/4 of 1%) per annum,
payable monthly beginning in the month in which the Letter of Credit Guaranty or
the Letter of Credit is first issued, on the outstanding amount of each Letter
of Credit less the amount of any and all amounts previously drawn under the
Letter of Credit.

                    8.12 Notwithstanding anything to the contrary contained in
this Section 8, there shall not be more than seven (7) Libor Tranches
outstanding at any one time.

                    8.13 Calculation of all amounts payable to CITBC under this
Financing Agreement with regard to Libor Loans shall be made whether or not
CITBC had actually funded the Libor Loans through the purchase of deposits in
the relevant market and currency, as the case may be, bearing interest at the
rate applicable to such Libor Loans, in an amount equal to the amount of the
Libor Loans and having a maturity comparable to the relevant Libor Period
provided, however, that a) CITBC may fund each of the Libor Loans in any manner
as CITBC sees fit without affecting the Companies' election, conversion or
continuation of a Libor Loan and b) the foregoing assumption shall be used only
for calculation of amounts payable under this Financing Agreement.

                    8.14 Notwithstanding anything to the contrary contained
herein, if any Libor Loan made under this Financing Agreement is prepaid, by
acceleration or otherwise (except if a Libor Loan is converted to a Chemical
Rate Loan pursuant to paragraph 8.17 or 8.19 hereof), the Companies must pay to
CITBC the Libor Prepayment Penalty.

                    8.15 The determination by CITBC of the amount of any loss or
expense with respect to or arising out of Libor Loans entered into under this
Financing Agreement shall be conclusive on the Companies in the absence of
manifest error when such loss or expense is set forth in a written notice to the
Companies in reasonable detail.

                    8.16 Notwithstanding anything herein to the contrary, in the
event that a Default occurs that has not been cured to the satisfaction of CITBC
or waived in writing by CITBC or an Event of Default occurs that has not been
waived in writing by CITBC, at CITBC's sole discretion, all Libor Loans then
outstanding shall convert immediately to Chemical Rate Loans. Such Libor Loans
shall be so converted without any further action by the Companies. The principal
amount of such loans shall bear interest at a rate equal to the Chemical Bank
Rate plus the


                                       72
<PAGE>   76

applicable Chemical Rate Margin (which may include any applicable default rate).

                    8.17 In the event that CITBC shall have determined in the
exercise of its reasonable business judgement (which determination shall be
conclusive and binding upon the Companies) that by reason of circumstances
affecting the interbank Eurodollar market, adequate and reasonable means do not
exist for ascertaining the Libor Rate applicable for any Libor Period with
respect to (a) a proposed loan that a Company has requested be made as a Libor
Loan, (b) a Libor Loan that will result from the requested conversion of a
Chemical Rate Loan into a Libor Loan, or (c) the continuation of a Libor Loan
beyond the expiration of the then current Libor Period with respect thereto,
CITBC shall give written notice of such determination to the Companies at least
one (1) day prior to, as the case may be, the requested borrowing date,
conversion date, or the last day of such Libor Period. If such notice is given
(i) any requested Libor Loan shall be made as a Chemical Rate Loan, (ii) any
Chemical Rate Loan that was to have been converted to a Libor Loan shall be
continued as a Chemical Rate Loan, and (iii) any outstanding Libor Loan shall be
converted, on the last day of then current Libor Period with respect thereto, to
a Chemical Rate Loan. Until such notice has been withdrawn by CITBC, no further
Libor Loans shall be made nor shall the Companies have the right to convert a
Chemical Rate Loan to a Libor Loan.

                    8.18 The applicable interest rate on Chemical Rate Loans
shall i) be calculated on the average of the portion of the net balances owing
by the applicable Company to CITBC in the Revolving Loan Account and/or on the
Capex Loan(s) as applicable, at the close of each day such loans are outstanding
during each month for which such Company has elected such Chemical Bank Rate and
ii) be prorated for the number of days of such month such loans are outstanding.

                    8.19 Notwithstanding any other provisions herein, if any
law, regulation, treaty or directive or any change therein or in the
interpretation or application thereof, shall make it unlawful for CITBC to make
or maintain Libor Loans as contemplated herein, the then outstanding Libor
Loans, if any, shall be converted automatically to Chemical Rate Loans on the

                                       73
<PAGE>   77

next succeeding interest payment date or within such earlier period as required
by law.

                    8.20 All interest, regardless of interest rate, shall be
payable monthly as of the end of each month, and shall be calculated based on a
360 day year. CITBC shall be entitled to charge the Companies' Revolving Loan
Accounts with the applicable interest rate(s) until all Obligations have been
paid in full.

                    8.21 The Companies hereby agree to indemnify CITBC and hold
CITBC harmless from any loss, cost or expense CITBC may sustain or incur as a
consequence of the failure by the Companies to complete any borrowing hereunder
at a Libor Rate after notice thereof has been given by the Companies to CITBC,
including, without limitation, any loss, cost or expense incurred by reason of
the liquidation or redeployment of deposits or other funds acquired by CITBC to
fund such borrowing when the applicable amount of the Revolving Loans and/or
Capex Loans, as result of such failure, is not made subject to such interest
rates on such date. CITBC shall certify the amount of its loss, cost or expense
to the Companies and such certification shall be final and conclusive absent
manifest error.

SECTION 9.  POWERS

                    The Companies hereby constitute CITBC or any person or agent

expense, to exercise all of the following powers, which being coupled with an
interest, shall be irrevocable until all of the Companies' Obligations to CITBC
have been paid in full:

this Section 10. The exercise of any option is not exclusive of any other option
which may be exercised at any time by CITBC.

                    10.3 Immediately upon the occurrence of any Event of
Default, CITBC may to the extent permitted by law: (a) remove from any premises
where same may be located any and all documents, instruments, files and records,
and any receptacles or cabinets containing same, relating to the Accounts, or
CITBC may use, at the Companies' expense, such of the Companies' personnel,
supplies or space at the Companies' places of business or otherwise, as may be
necessary to properly administer and control the Accounts or the handling of
collections and realizations thereon; (b) bring suit, in the name of any Company
or CITBC, and generally shall have all other rights respecting said Accounts,
including without limitation the right to: accelerate or extend the time of
payment, settle, compromise, release in whole or in part any amounts owing on
any Accounts and issue credits in the name of any Company or CITBC; (c) sell,
assign and deliver the Collateral and any returned, reclaimed or repossessed
merchandise, with or without advertisement, at public or private sale, for cash,
on credit or otherwise, at CITBC's sole option and discretion, and CITBC may bid
or become a purchaser at any such sale, free from any right of redemption, which
right is hereby expressly waived by the Companies; (d) foreclose the security
interests created herein by any available judicial procedure, or to take
possession of any or all of the Inventory and Equipment without judicial
process, and to enter any premises where any Inventory and Equipment may be
located for the purpose of taking possession of or removing the same and (e)
exercise any other rights and remedies provided in law, in equity, by contract
or otherwise. CITBC shall have the right, without notice or advertisement, to
sell, lease, or otherwise dispose of all or any part of the Collateral whether
in its then condition or after further preparation or processing, in the name of
any Company or 


                                       78
<PAGE>   82

CITBC, or in the name of such other party as CITBC may designate, either at
public or private sale or at any broker's board, in lots or in bulk, for cash or
for credit, with or without warranties or representations, and upon such other
terms and conditions as CITBC in its sole discretion may deem advisable, and
CITBC shall have the right to purchase at any such sale. If any Inventory and
Equipment shall require rebuilding, repairing, maintenance or preparation, CITBC
shall have the right, at its option, to do such of the aforesaid as is
necessary, for the purpose of putting the Inventory and Equipment in such
saleable form as CITBC shall deem appropriate. The Companies agree, at the
request of CITBC, to assemble the Inventory and Equipment and to make it
available to CITBC at premises of the Companies or elsewhere and to make
available to CITBC the premises and facilities of the Companies for the purpose
of CITBC's taking possession of, removing or putting the Inventory and Equipment
in saleable form. However, if notice of intended disposition of any Collateral
is required by law, it is agreed that ten (10) days notice shall constitute
reasonable notification and full compliance with the law. The net cash proceeds
resulting from CITBC's exercise of any of the foregoing rights, (after deducting
all charges, costs and expenses, including reasonable attorneys' fees) shall be
applied by CITBC to the payment of the Companies' Obligations, whether due or to
become due, in such order as CITBC may elect, and the Companies shall remain
liable to CITBC for any deficiencies, and CITBC in turn agrees to remit to the
Companies or their successors or assigns, any surplus resulting therefrom. The
enumeration of the foregoing rights is not intended to be exhaustive and the
exercise of any right shall not preclude the exercise of any other rights, all
of which shall be cumulative. The mortgage, deed of trust or assignment on the
Real Estate shall govern the rights and remedies of CITBC with respect thereto.

                    10.4 CITBC may, at its election, with respect to any sale of
all or any part of the Stock Collateral, limit purchasers to those who will
agree, among other things, to acquire the Stock Collateral for their own
account, for investment and not with a view to distribution or resale. The
Companies acknowledge that any such private sales may be at prices and on terms
less favorable to CITBC than those obtainable through a public sale without such
restrictions and, notwithstanding such


                                       79
<PAGE>   83

circumstances, agree that any such private sale shall be deemed to have
been made in a commercially reasonable manner and that CITBC shall have no
obligation to engage in public sales and no obligation to delay the sale of any
Stock Collateral for the period of time necessary to permit the respective
issuer of such Stock Collateral to register it for public sale.

SECTION 11. GUARANTY OF OBLIGATIONS. In order to induce CITBC to enter into this
Financing Agreement and to make the Revolving Loans, Capex Loans and other loans
and credit accommodations to the Companies hereunder and to issue Letters of
Credit for the account of the Companies hereunder, each Company agrees as
follows:

                    11.1 GUARANTY Each Company unconditionally and irrevocably
guaranties, as primary obligor and not merely as a surety, the due and punctual
payment when due (whether by required prepayment, declaration, demand or
otherwise) (including amounts that would become due but for the operation of the
automatic stay under Section 362(a) of the Bankruptcy Code, 11 U.S.C.
Section 362(a)) of all Obligations of the other Companies (including, without
limitation, interest which, but for the filing of a petition in bankruptcy with
respect to the Companies would accrue on such Obligations). If any or all of the
Obligations becomes due and payable, such Company unconditionally, absolutely
and irrevocably promises to pay such Obligations to CITBC for application
thereto, on demand by CITBC, in lawful money of the United States of America and
in immediately available funds. Unpaid Obligations shall bear interest at the
Default Rate of Interest. For purposes of this Section 11, the obligations of
each Company under this Section 11 are referred to as such Company's "Guaranty."

                    11.2 TERMS OF GUARANTIES (a) Each Company agrees that the
Obligations of the other Companies may be extended or renewed, and the Revolving
Loans repaid and reborrowed in whole or in part, without notice or further
assent, and that it will remain bound upon its Guaranty notwithstanding any
extension, renewal or other alteration of any such Obligations or repayment and
reborrowing of the Revolving Loans.

                                       80
<PAGE>   84

                    (b) Each Company waives presentation of, demand of, payment
from and protest of any Obligation of the other Companies and also waives notice
of protest for nonpayment. The obligations of each Company under this Guaranty
shall not be affected by, and each Company hereby waives its rights (to the
extent permitted by law) in connection with:

                              (i) the failure of CITBC to assert any claim or
                    demand or to enforce any right or remedy against the
                    Companies under the provisions of this Financing Agreement
                    or any other agreement or otherwise;

                              (ii) any extension or renewal of any provision
                    hereof or thereof;

                              (iii) any rescission, waiver, amendment or
                    modification of any of the terms or provisions of this
                    Financing Agreement or any instrument executed pursuant
                    hereto;

                              (iv) the release of any security held by CITBC for
                    the Obligations of any Company;

                              (v) the failure of CITBC to exercise any right or
                    remedy against any other guarantor of the Obligations of the
                    Companies;

                              (vi) CITBC taking and holding security or
                    collateral for the payment of a Company's Guaranty, any
                    other guaranties of the Obligations or other liabilities of
                    a Company or the Obligations guarantied hereby, and
                    exchanging, enforcing, waiving and releasing any such
                    security or collateral;

                              (vii) CITBC applying any such security or
                    collateral and directing the order or manner of sale thereof
                    as CITBC in its discretion may determine; or

                              (viii) CITBC settling, releasing, compromising,
                    collecting or otherwise liquidating the 

                                       81
<PAGE>   85


                    Obligations of any Company and any security or collateral
                    therefor in any manner determined by CITBC.

                    (c) Each Company waives any benefits such Company may
otherwise derive from Section 580a of the California Code of Civil Procedure or
any comparable provisions of the laws of any other jurisdiction. Without
limiting the foregoing, each Company expressly waives any right to a "fair
value" hearing following a judicial or nonjudicial foreclosure with respect to
any interest in real property or other collateral serving as security for all or
any part of the Obligations of the Companies.

                    (d) CITBC may, at its election, foreclose on any security
held by CITBC by one or more judicial or nonjudicial sales, or exercise any
other right or remedy CITBC may have against the Companies or any security
without affecting or impairing in any way the liability of each Company under
this Section 11, except to the extent the Obligations have been indefeasibly
paid.

                    (e) Each Company acknowledges that it has been made aware of
the provisions of California Civil Code section 2856, has read and understands
the provisions of that statute, has been advised by its counsel as to the scope,
purpose and effect of that statute, and based thereon, and without limiting the
foregoing waivers, such Company agrees to waive all suretyship rights and
defenses described in Civil Code sections 2856(a) and (b). Without limiting any
other waivers herein, each Company hereby gives the following waiver pursuant to
Section 2856(b) of the California Civil Code:

                    "The Company waives all rights and defenses arising out of
                    an election of remedies by CITBC, even though that election
                    of remedies, such as a nonjudicial foreclosure with respect
                    to security for a guaranteed obligation, has destroyed such
                    Company's rights of subrogation and reimbursement against
                    the principal by the operation of Section 580d of the

                                       82
<PAGE>   86

                    California Code of Civil Procedure or otherwise."

                    (f) Each Company further agrees that this Guaranty
constitutes a guaranty of payment when due and not of collection, and waives any
right to require that any resort be had by CITBC or any other person to any
security held for payment of the Obligations of the Companies or to any balance
of any deposit or account or credit on the books of CITBC or any other person in
favor of the Companies or any other person.

                    (g) The obligations of each Company under this Guaranty
shall not be subject to any reduction, limitation, impairment or termination for
any reason, including, without limitation, any claim of waiver, release,
surrender, alteration or compromise, and shall not be subject to any defense or
setoff, counterclaim, recoupment or termination whatsoever by reason of the
invalidity, illegality or unenforceability of the Obligations, discharge of any
Company from the Obligations in a bankruptcy or similar proceeding or otherwise.
Without limiting the generality of the foregoing, the obligations of each
Company under this Guaranty shall not be discharged or impaired or otherwise
affected by the failure of CITBC to assert any claim or demand or to enforce any
remedy under this Financing Agreement, any Loan Document or any other agreement,
by any waiver or modification of any provision thereof, by any default, failure
or delay, willful or otherwise, in the performance of the Obligations of the
Companies, or by any other act or thing or omission or delay to do any other act
or thing that may or might in any manner or to any extent vary the risk of a
Company, or otherwise operate as a discharge of a Company as a matter of law or
equity.

                    (h) Each Company further agrees that this Guaranty shall
continue to be effective or be reinstated, as the case may be, if at any time
payments, or any part thereof, of principal of or interest on any Obligation of
any Company is rescinded or must otherwise be restored by CITBC upon the
bankruptcy or reorganization of such Company or otherwise.

                    (i) Each Company further agrees, in furtherance of the
foregoing and not in limitation of any other right that CITBC


                                       83
<PAGE>   87

may have at law or in equity against such Company by virtue hereof, upon the
failure of a Company to pay any of its Obligations when and as the same shall
become due (whether by required prepayment, declaration, demand or otherwise),
such Company will forthwith pay, or cause to be paid, in cash, to CITBC an
amount equal to the sum of the unpaid principal amount of such Obligations,
accrued and unpaid interest on such Obligations and all other unpaid Obligations
to CITBC. The Collateral pledged by each Company pursuant this Financing
Agreement shall secure its obligations under this Section 11.

                    (j) Each Company hereby irrevocably waives (a) any right of
subrogation, contribution, indemnity or otherwise against the other Companies
that may arise out of or be caused by its Guaranty hereunder, (b) all rights
and/or claims against the other Companies which may arise by reason of such
Company's Guaranty, (c) any right to enforce any remedy that CITBC now has or
may hereafter have against the Companies, and (d) any benefit of, and any right
to participate in, any security now or hereafter held by CITBC.

                    (k) Any inter-Company Indebtedness now or hereafter created
is hereby subordinated in right of payment to the Obligations, and any such
inter-Company Indebtedness collected or received by any Company after an Event
of Default has occurred and while it is continuing shall be held in trust for
CITBC and shall forthwith be paid over to CITBC to be credited and applied to
the Obligations but without affecting, impairing or limiting in any manner the
liability of each Company under its Guaranty.

                    11.3 SEPARATE ACTION. CITBC may bring and prosecute a
separate action or actions against any Company whether or not any other Company,
any other guarantor or any other person is joined in any such action or a
separate action or actions are brought against any other Company, any other
guarantor, any other person, or any Collateral for all or any part of the
Obligations. The obligations of each Company under, and the effectiveness of,
this Section 11 are not conditioned upon the existence or continuation of any
other guarantee (including any letter of credit) of all or any part of the
Obligations.

                                       84
<PAGE>   88

                    11.4 LIMITATION ON GUARANTEE OBLIGATIONS. In any action or
proceeding involving any state corporate law, or any state or Federal
bankruptcy, insolvency, reorganization or other law affecting the rights of
creditors generally, if the obligations of any Company under this Section 11
would otherwise, taking into account the provisions of paragraph 11.3 of this
Section 11, be held or determined to be void, invalid or unenforceable, or
subordinated to the claims of any other creditors, on account of the amount of
its liability under this Section 11, then, notwithstanding any other provision
of this Section 11 to the contrary, the amount of such liability shall, without
any further action by such Company, CITBC or any other person, be automatically
limited and reduced to the highest amount which is valid and enforceable and not
subordinated to the claims of other creditors as determined in such action or
proceeding.

SECTION 12.  TERMINATION

                    Except as otherwise permitted herein, the Companies or CITBC
may terminate this Financing Agreement and the Line of Credit only as of the
fifth or any subsequent Anniversary Date and then only by giving the other at
least sixty (60) days prior written notice of termination. Notwithstanding the
foregoing, CITBC may terminate the Financing Agreement immediately upon the
occurrence of an Event of Default, provided, however, that if the Event of
Default is an event listed in paragraph 10.1(c) of Section 10 of this Financing
Agreement, CITBC may regard the Financing Agreement as terminated and notice to
that effect is not required. This Financing Agreement, unless terminated as
herein provided, shall automatically continue from Anniversary Date to
Anniversary Date. Notwithstanding the foregoing, the Companies may terminate
this Financing Agreement and the Line of Credit prior to the fifth Anniversary
Date upon sixty (60) days' prior written notice to CITBC, provided that the
Companies pay to CITBC immediately on demand, the Early Termination Fee and/or
the Libor Prepayment Penalty, if applicable. All Obligations shall become due
and payable as of any termination hereunder or under Section 10 hereof and,
pending a final accounting, CITBC may withhold any balances in the Companies'
accounts (unless supplied with an indemnity satisfactory to CITBC) to cover all
of the Companies' Obligations, whether absolute or contingent. All of 


                                       85
<PAGE>   89

CITBC's rights, liens and security interests shall continue after any
termination until all Obligations have been paid and satisfied in full.

SECTION 13.  MISCELLANEOUS

                    13.1 Each Company hereby waives diligence, demand,
presentment and protest and any notices thereof as well as notice of nonpayment
(except notices expressly required pursuant to Section 10). No delay or omission
of CITBC or the Companies to exercise any right or remedy hereunder, whether
before or after the happening of any Event of Default, shall impair any such
right or shall operate as a waiver thereof or as a waiver of any such Event of
Default. No single or partial exercise by CITBC of any right or remedy precludes
any other or further exercise thereof, or precludes any other right or remedy.

                    13.2 THIS WRITTEN AGREEMENT AND THE OTHER DOCUMENTS
REFERENCED HEREIN OR CONTEMPLATED HEREBY REPRESENT THE FINAL AGREEMENT AMONG THE
PARTIES HERETO AND SUPERSEDE ALL PRIOR AGREEMENTS, UNDERSTANDINGS AND
INDUCEMENTS, WHETHER EXPRESS OR IMPLIED, ORAL OR WRITTEN, INCLUDING, WITHOUT
LIMITATION, THE AUGUST 17, 1994 FINANCING AGREEMENT. THIS WRITTEN AGREEMENT MAY
NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL OR
WRITTEN AGREEMENTS OF THE PARTIES HERETO. THERE ARE NO UNWRITTEN ORAL AGREEMENTS
AMONG THE PARTIES.

                    13.3 In no event shall the Companies, upon demand by CITBC
for payment of any indebtedness relating hereto, by acceleration of the maturity
thereof, or otherwise, be obligated to pay interest and fees in excess of the
amount permitted by law. Regardless of any provision herein or in any agreement
made in connection herewith, CITBC shall never be entitled to receive, charge or
apply, as interest on any indebtedness relating hereto, any amount in excess of
the maximum amount of interest permissible under applicable law. It is the
intent of the Companies and CITBC to conform strictly to all applicable state
and federal usury laws. All agreements between the Companies and CITBC whether
now existing or hereafter arising and whether written or oral, are hereby
expressly limited so that in no contingency or event whatsoever, whether by
reason of acceleration of the maturity hereof or otherwise, shall the


                                       86
<PAGE>   90

amount contracted for, charged or received by CITBC for the use, forbearance, or
detention of the money loaned hereunder or otherwise, or for the payment or
performance of any covenant or obligation contained herein or in any other
document evidencing, securing or pertaining to the Obligations evidenced hereby
which may be legally deemed to be for the use, forbearance or detention of
money, exceed the maximum amount which the Companies are legally entitled to
contract for, charge or collect under applicable state or federal law. If from
any circumstance whatsoever fulfillment of any provision hereof or of such other
documents, at the time performance of such provision shall be due, shall involve
transcending the limit of validity prescribed by law, then the obligation to be
fulfilled shall be automatically reduced to the limit of such validity, and if
from any such circumstance CITBC shall ever receive as interest or otherwise an
amount in excess of the maximum that can be legally collected, then such amount
which would be excessive interest shall be applied to the reduction of the
principal indebtedness hereof and any other amounts due with respect to the
Obligations evidenced hereby, but not to the payment of interest and if such
amount which would be excessive interest exceeds the Obligations and all other
non interest indebtedness described above, then such additional amount shall be
refunded to the Companies. This paragraph shall control every other provision
hereof and of any other agreement made in connection herewith.

                    13.4 If any provision hereof or of any other agreement made
in connection herewith is held to be illegal or unenforceable, such provision
shall be fully severable, and the remaining provisions of the applicable
agreement shall remain in full force and effect and shall not be affected by
such provision's severance. Furthermore, in lieu of any such provision, there
shall be added automatically as a part of the applicable agreement a legal and
enforceable provision as similar in terms to the severed provision as may be
possible.

                    13.5 EACH COMPANY AND CITBC EACH HEREBY WAIVE ANY RIGHT TO A
TRIAL BY JURY IN ANY ACTION OR PROCEEDING ARISING OUT OF THIS FINANCING
AGREEMENT. EACH COMPANY HEREBY IRREVOCABLY WAIVES PERSONAL SERVICE OF PROCESS
AND CONSENTS TO SERVICE OF PROCESS BY CERTIFIED OR REGISTERED MAIL, RETURN
RECEIPT REQUESTED.
