                (a) Restructured Notes. Each of the Restructure Lenders
severally agrees, on the terms and conditions set forth in this Agreement, to
restructure the Existing Facilities and Existing Notes. The Restructured Loans
shall be evidenced by promissory notes of the Borrower, substantially in the
form of Exhibit A, with appropriate insertions (the "Restructured Notes"),

of the Borrower to pay the aggregate unpaid principal amount of the Restructured
Loan owed by the Borrower to such Restructure Lender, with interest thereon as
prescribed in Sections 4.3, 5.1 and 5.2 hereof. Upon receipt by the Restructure
Agent of the Restructured Notes executed by the Borrower to the order of the
respective Restructure Lenders, the Existing Notes shall be canceled, subject to
Section 12.13 hereof. Each Restructure Lender is hereby authorized to record in
its respective books and records, and on any exhibit annexed to the Restructured
Notes, the date and amount of each Restructure Loan made by said Restructure
Lender, and the date and amount of each payment of principal thereof, and any

holders of such Restructured Loan or Restructured Loan or portion thereof. Any
such new Restructured Note shall thereafter be considered a Restructured Note
under this Agreement. Any such new Restructured Note shall carry the rights to
accrued and unpaid interest which were carried by the Restructured Note so
exchanged so that neither gain nor loss of interest shall result from such
event.

                (b) Restructure Fee. On or before the Closing Date, the Borrower
shall pay to Restructure Agent a fee of $1,950,000.00 (the "Restructure Fee").
Such fees shall be distributed to each agent of the Existing Facilities pro rata
in accordance with the amounts of the Existing Facilities and then disbursed to
the Restructure Lenders in a manner to be determined by the agent of the
Existing Facility applicable to each Restructure Lender.

        SECTION 4.2 REPAYMENT.

                (a) Mandatory Repayments. The Borrower shall repay

mandatory principal amortization payments in the amount of $1,000,000.00 for
each fiscal quarter commencing with the fiscal quarter ending July 2, 2000. Such
minimum mandatory principal amortization payments for each fiscal quarter shall
be due and payable on the tenth calendar day of the month succeeding the end of
each applicable fiscal quarter from and after the fiscal quarter ending July 2,
2000. Such minimum mandatory principal amortization payments may be deferred by
the Borrower if and only if, as a result of such payment, the Borrower's cash
balance would be less than $35,000,000.00 after giving effect to such minimum
mandatory principal amortization payment. In the event that any such payment is
so deferred, each such deferred payment shall be made up by the Borrower in the
scheduled quarterly minimum mandatory principal amortization payments for the
following fiscal quarters to the extent that such payments would not result in a
cash balance of less than $35,000,000.00, until all such payments have been made
in full.

                (c) Optional Payment. The Borrower may at its option and without
penalty repay the Restructured Loans, in whole or in part, on any Business Day,
prior to the Restructure Maturity Date, from time to time, provided Restructure
Agent shall have received from the Borrower notice of any such payment at least
one Business Day prior to the date of the proposed payment. For Restructured
Loans, each day shall be defined as and constitute an "Interest Period." Partial
payments hereunder shall be in an aggregate principal amount of not less than
$1,000,000.00 and in an integral multiple of $100,000.00 for the Restructured
Loans. Restructure Agent shall promptly inform the Restructure Lenders by
telecopy of receipt of each such payment.

Lenders when the amount due the Restructure Lenders equals or exceeds
$500,000.00, but in no event later than the end of each fiscal quarter of the
Borrower.

                (f) Cash Balance. Commencing with the Borrower's fiscal quarter
ended on July 2, 2000 and for each fiscal quarter thereafter until the
Restructure Maturity Date, the Borrower shall prepay the outstanding
Restructured Loans on the tenth day of the month following the end of the
Borrower's fiscal quarter in an amount equal to fifty percent of the Cash
balance at the quarter ended in excess of $40,000,000.00 up to a maximum payment
each quarter of $7,500,000.00; provided, however, that the amount of any
proceeds received by the Borrower in connection with a capital raising event
described in Section 4.2(d) or any sale of assets subject to the prepayment
requirement set forth in Section 4.2(e) shall be excluded from the calculation
of the Cash balance for purposes of this Section 4.2(f); and provided, further,
however, that any amounts representing minimum mandatory principal amortization
payments for the applicable quarter pursuant to Section 4.1(b) shall be included
in calculating the aforementioned $7,500,000.00 limit for each quarter. Each
such payment shall be accompanied by a certificate signed by the Borrower's
chief financial officer certifying the manner in which the Cash balance and the
resulting prepayment were calculated, which certificate shall be in form and
substance reasonably satisfactory to Restructure Agent. Notwithstanding the
foregoing, the portion of any excess cash flow payment due pursuant to this
Section 4.2(f) that, if timely paid, would be the sole cause of the Borrower
being in breach of Section 8.2(b) or 8.2(c) shall be deferred until such time as
the Borrower can pay such sum without being in breach of Section 8.2(b) or
8.2(c), and such deferral shall not constitute a Restructure Event of Default.

                (g) Implied Consent. Nothing in this Section 4.2 shall be
construed to constitute either Restructure Agent's or any Restructure Lender's
consent to any transaction referred to in Sections 4.2(d) or (e) above which are
not expressly permitted by other provisions of the Restructure Loan Documents.

                (h) Allocation of Payments. Prior to the occurrence of a
Restructure Event of Default, all amounts received by Restructure Agent on
account of the Restructured Loans, except

                                       15
<PAGE>   21

expressly as set forth to the contrary in other Sections of this Agreement,
shall be disbursed by Restructure Agent to the Restructure Lenders pro rata in
accordance with their respective Restructured Loans Percentage in inverse order
of maturity by wire transfer on the date of receipt if received by Restructure
Agent before 1:00 p.m. (Eastern Time) or, if received later, by 1:00
p.m.(Eastern Time) on the next succeeding Business Day, without further interest
payable by Restructure Agent. Following the occurrence of a Restructure Event of
Default, all amounts received by Restructure Agent on account of the
Restructured Loans shall be disbursed by Restructure Agent as follows:

                        (1) first, to the payment of expenses incurred by
Restructure Agent in the performance of its duties and enforcement of the rights
under the Restructure Loan Documents, including, without limitation, all costs
and expenses of collection, attorneys' fees and court costs;

                        (2) then, to the payment of expenses incurred by the
agents of the Existing Facilities in the performance of their duties and
enforcement of their rights under the Restructure Loan Documents, including,
without limitation, all costs and expenses of collection, attorneys' fees and
court costs;

                        (3) then, to the Restructure Lenders, pro rata in
accordance with their respective Restructured Loans Percentage until all
outstanding Restructured Loans and interest accrued thereon have been paid in
full; and

                        (4) then, to such Persons as may be legally entitled
thereto.

                (i) Sharing of Payments. Except where a provision of this
Agreement provides for non-pro rata treatment, if any Restructure Lender shall
receive and retain any payment, whether by setoff, application of the deposit
balance or security, or otherwise, in respect of the Restructured Loans in
excess of such Restructure Lender's Restructured Loans Percentage, then such
Restructure Lender shall purchase from the other Restructure Lenders for cash
and at face value and without recourse, such participation in the Restructured
Loans held by them as shall be necessary to cause such excess payment to be
shared ratably as aforesaid with each of them; provided, however, that if such
excess payment or part thereof is thereafter recovered from such purchasing
Restructure Lender, the related purchases from the other Restructure Lenders
shall be rescinded ratably and the purchase price restored as to the portion of
such excess payment so recovered, but without interest. Each Restructure Lender
agrees to exercise any and all rights of setoff, counterclaim or banker's lien
first fully against the Restructured Loans held by such Restructure Lender, and
only then to any other obligations of the Borrower to such Restructure Lender.

        SECTION 4.3 INTEREST RATE AND PAYMENT DATES.

                (a) Payment of Interest. Interest with respect to each
Restructured Loan shall be payable in arrears on each Interest Payment Date. In
no event shall interest on a Restructured Loan exceed the maximum rate permitted
by applicable law.

                                       16
<PAGE>   22

                (b) Base Rate. The Restructured Loans shall bear interest on the
unpaid principal amount thereof from the Closing Date through the Restructure
Maturity Date at a rate per annum equal to the Base Rate plus 125 basis points.
The Restructure Agent shall notify the Borrower and each Restructure Lender of
the amount and the effective date of each adjustment in the Base Rate; provided,
however, that no failure or delay in giving any such notice shall affect or
delay the making of any such adjustments or the obligation of the Borrower to
pay in a timely manner the interest due on such Restructured Loans.

                (c) Catch-Up Interest. The Borrower shall, on or before the
Closing Date, pay interest ("Catch-Up Interest") to each Restructure Lender
which is a lender (or participant) under the IBJ Facility I, IBJ Facility II or
DKB Facility in an amount equal to the product of the difference between the
applicable interest rates for each applicable interest period under such
applicable facility and the FNB Facility from June 30, 1998 through the Closing
Date, multiplied by the outstanding principal amount of such Restructure
Lender's Existing Loan during each such period.

                                    ARTICLE 5

              GENERAL PROVISIONS CONCERNING THE RESTRUCTURED LOANS

        SECTION 5.1 DEFAULT INTEREST. So long as a Potential Restructure Event
of Default or Restructure Event of Default shall have occurred and be continuing
under Section 9.1(f), and without the necessity of notice from Restructure Agent
or any Restructure Lender to the Borrower, or so long as any other Potential
Restructure Event of Default or Restructure Event of Default shall have occurred
and be continuing and, at the election of Restructure Agent and Majority
Restructure Lenders, confirmed by written notice from Restructure Agent to the
Borrower, the interest rate applicable to the Restructured Loans shall be
increased by 200 basis points per annum above such rate otherwise applicable to
the Restructured Loans (the "Default Rate") and each Restructure Loan shall bear
interest at the Default Rate. Interest at the Default Rate shall accrue from the
initial date of such Potential Restructure Event of Default or Restructure Event
of Default until that Potential Restructure Event of Default or Restructure
Event of Default is cured or waived and shall be payable upon demand.

        SECTION 5.2 COMPUTATION OF INTEREST.

                (a) Calculations. Interest in respect of the Base Rate shall be
calculated on the basis of a 365-day year for the actual days elapsed. Any
change in the interest rate resulting from a change in the Base Rate shall
become effective as of the opening of business on the day on which such change
in the Base Rate shall become effective.

                (b) Determination by Restructure Agent. Each determination of an
interest rate or fee by Restructure Agent pursuant to any provision of this
Agreement shall be conclusive and binding on the Restructure Lenders and the
Borrower in the absence of manifest error.

                                       17
<PAGE>   23

        SECTION 5.3 PAYMENTS. The Borrower shall make each payment of principal,
interest and fees due from it hereunder and under the Restructured Notes,
WITHOUT SETOFF OR COUNTERCLAIM AND FREE AND CLEAR OF, AND WITHOUT ANY DEDUCTION
OR WITHHOLDING FOR, ANY TAXES OR OTHER PAYMENTS, on or before 12:00 P.M.
(Eastern Time) on the day when due to Restructure Agent, on behalf of the
Restructure Lenders, at the head office of Restructure Agent OR SUCH OTHER PLACE
AS IT MAY FROM TIME TO TIME SPECIFY IN WRITING in immediately available UNITED
STATES DOLLARS.

        SECTION 5.4 PAYMENT ON NON-BUSINESS DAYS. Whenever any payment to be
made hereunder or under the Restructured Loans shall be stated to be due on a
day which is not a Business Day, such payment may be made on the next succeeding
Business Day, and with respect to payments of principal, interest thereon shall
be payable at the then applicable rate during such extension.

        SECTION 5.5 REDUCED RETURN. If any Restructure Lender shall have
determined that any new or additional applicable law, regulation, rule or
regulatory requirement (collectively, in this Section 5.5, "Requirement")
regarding capital adequacy, or any change therein, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by said Restructure Lender with any new or additional
request or directive regarding capital adequacy (whether or not having the force
of law) of any such authority, central bank or comparable agency, in any such
case, effective after the Closing Date, has or would have the effect of reducing
the rate of return on said Restructure Lender's capital as a consequence of its
Restructured Loan and obligations hereunder to a level below that which would
have been achieved but for such Requirement, change or compliance (taking into
consideration said Restructure Lender's policies with respect to capital
adequacy) by an amount deemed by said Restructure Lender to be material (which
amount shall be determined by said Restructure Lender's reasonable allocation of
the aggregate of such reductions resulting from such events), then from time to
time, within thirty (30) Business Days after written demand by said Restructure
Lender, the Borrower shall pay to Restructure Agent on behalf of said
Restructure Lender such additional amount or amounts as will compensate said
Restructure Lender for such reduction. Notwithstanding the foregoing, no
additional compensation will be required from the Borrower under this Section
5.5 if the reason for said additional compensation was based solely on said
Restructure Lender's failure to comply with any existing or new law, treaty,
rule or regulation or requirement. In addition, said Restructure Lender shall
promptly notify the Borrower of any proposed request for compensation under this
Section 5.5 and shall provide the Borrower with reasonable support therefor. Any
request by said Restructure Lender for additional compensation shall be
structured to allocate such additional costs over the term of the credit
affected thereby. The Borrower may, at its option, replace any Restructure
Lender assessing additional charges under this Section 5.5 with a new
Restructure Lender with the prior written consent of the Restructure Agent,
which consent shall not be unreasonably withheld or delayed; provided, however,
the Borrower may not require, and this sentence shall not be deemed to be the
agreement of, any Restructure Lender to replace any other Restructure Lender.

        SECTION 5.6 INDEMNITIES. Whether or not the transactions contemplated
hereby shall be consummated, the Borrower agrees to indemnify, pay and hold
Restructure Agent and

                                       18
<PAGE>   24

the Restructure Lenders, and the shareholders, officers, directors, employees
and agents of same, harmless from and against any and all claims, liabilities,
losses, damages, costs and expenses (whether or not any of the foregoing Persons
is a party to any litigation), including, without limitation, reasonable
attorneys' fees and costs (including, without limitation, the reasonable
estimate of the allocated cost of in-house legal counsel and staff) and costs of
investigation, document production, attendance at a deposition, or other
discovery, with respect to or arising out of (i) any proposed acquisition by the
Borrower or any of its Consolidated Subsidiaries of any Person or any securities
(including a self-tender), (ii) this Agreement or any use of proceeds hereunder,
or (iii) any claim, demand, action or cause of action being asserted against the
Borrower or any of its Consolidated Subsidiaries (collectively, the "Indemnified
Liabilities"); provided, however, that the Borrower shall have no obligation
hereunder with respect to Indemnified Liabilities arising from the gross
negligence or willful misconduct of any such Persons or the failure of such
Person to comply with applicable law, including, without limitation, the failure
of any non-U.S. Person to file the appropriate forms required by any taxing
authority having jurisdiction over such Person or this Agreement and the
transactions contemplated hereby. If any claim is made, or any action, suit or
proceeding is brought against any Person indemnified pursuant to this Section
5.6, the indemnified Person shall notify the Borrower of such claim or of the
commencement of such action, suit or proceeding, and the Borrower will assume
the defense of such action, suit or proceeding, employing counsel selected by
the Borrower and reasonably satisfactory to the indemnified Person, and pay the
fees and expenses of such counsel. This covenant shall survive termination of
this Agreement and payment of the outstanding Restructured Loans.

        SECTION 5.7 REQUIREMENTS OF LAW. In the event that any law, regulation
or directive or any change therein or in the interpretation or application
thereof or compliance by any Restructure Lender with any request or directive
(whether or not having the force of law) from any central bank or other
governmental authority, agency or instrumentality, in any case, effective after
the Closing Date:

                (a) does or shall subject said Restructure Lender to any new or
additional tax of any kind whatsoever with respect to this Agreement, any
Restructured Loan made hereunder, or change the basis of taxation of payments to
said Restructure Lender of principal, restructure fee, interest or any other
amount payable hereunder (except for changes in the rate of tax on the overall
net income of said Restructure Lender);

                (b) does or shall impose, modify or hold applicable any reserve,
assessment rate, special deposit, compulsory loan or other requirement
(collectively in this Section 5.7, "Requirements") against assets held by, or
deposits or other liabilities in or for the account of, advances or loans by, or
other credit extended by, or any other acquisition of funds by, any office of
said Restructure Lender.

                (c) does or shall impose, modify or hold applicable any of the
Requirements against the Restructure Loans Percentages; or

                (d) does or shall impose on said Restructure Lender any other
new or additional condition;

                                       19
<PAGE>   25

and the result of any of the foregoing is to increase the cost to said
Restructure Lender of making, renewing or maintaining its Restructured Loan or
to reduce any amount receivable thereunder by an amount determined by said
Restructure Lender, in its sole discretion, to be material (which increase or
reduction shall be determined by the Restructure Lender's reasonable allocation
of the aggregate of such cost increases or reduced amounts receivable resulting
from such events), then, in any such case, the Borrower shall pay to Restructure
Agent on behalf of said Restructure Lender, within thirty (30) Business Days of
its demand, any additional amounts necessary to compensate said Restructure
Lender for such additional cost or reduced amount receivable as determined by
said Restructure Lender with respect to this Agreement. If said Restructure
Lender becomes entitled to claim any additional amounts pursuant to this
subsection, it shall notify the Borrower of the event by reason of which it has
become so entitled. A statement incorporating the calculation as to any
additional amounts payable pursuant to the foregoing sentence submitted by said
Restructure Lender to the Borrower shall be conclusive in the absence of
manifest error. Notwithstanding the foregoing, no additional compensation will
be required from the Borrower under this Section 5.7 if the reason for said
additional compensation was based solely on said Restructure Lender's failure to
comply with any existing or new law, treaty, rule or regulation or requirement.
In addition, said Restructure Lender shall promptly notify the Borrower of any
proposed request for compensation under this Section 5.7 and shall provide the
Borrower with reasonable support therefor. Any request by said Restructure
Lender for additional compensation shall be structured to allocate such
additional costs over the term of the credit affected thereby. The Borrower may,
at its option, replace any Restructure Lender assessing additional charges under
this Section 5.7 with a new Restructure Lender with the prior consent of the
Restructure Agent, which consent shall not be unreasonably withheld or delayed;
provided, however, the Borrower may not require, and this sentence shall not be
deemed to be the agreement of, any Restructure Lender to replace any other
Restructure Lender.

        SECTION 5.8 IBJ BANK GROUP II SWAP TRANSACTIONS. The Borrower
acknowledges that in connection with the IBJ Facility II, the IBJ Bank Group II
entered into certain interest rate swap transactions (the "IBJ Bank Group II
Swap Transactions"), to which the Borrower is not a party. As a further
inducement to the Restructure lenders in the IBJ Bank Group II to enter into the
Restructure Agreement, the Borrower agrees as follows:

                (a) Interest Rate Swap Deferral Fee. Borrower shall pay a fee
(the "Interest Rate Swap Deferral Fee") to IBJ, as payment agent for the
Restructure Lenders in the IBJ Bank Group II, payable in arrears on the 6th day
of March, June, September and December of each year (each, a "Payment Date"),
equal to the product of (i) the amount, if any, by which (i) 6.7085% exceeds
(ii) the Three Month USD-LIBOR-BBA at TELERATE 3750 for the three month period
ending on such Payment Date, calculated on the basis of actual days elapsed and
a 360-day year, and (ii) the aggregate notional amount of the IBJ Bank Group II
Swap Transactions as of such Payment Date (as such notional amount may have been
or maybe deemed to have been reduced, terminated or canceled as a result of
amounts attributable to a Borrower's Election (as defined below) or payments or
prepayments made by the Borrower on or prior to such Payment Date in respect of
the Restructure Loans attributable to the Existing Loans under the IBJ Facility
II). Such LIBOR rate shall be reset for the following three month period two
Business Days prior to

                                       20
<PAGE>   26

each Payment Date, using London and New York Holidays and the Modified Following
Day Convention.

                (b) Borrower's Election. The Borrower may elect at any time on
or prior to the Restructure Maturity Date to cause all of the Restructure
Lenders in the IBJ Bank Group II to cancel and/or terminate their interests in
the IBJ Bank Group II Swap Transactions, in whole or part, upon three Business
Days' notice to IBJ, as payment agent for the IBJ Bank Group II (a "Borrower's
Election"). In the event of a Borrower's Election that does not terminate the
IBJ Bank Group II Swap Transactions in full, the Borrower shall be obligated to
continue to pay the Interest Rate Swap Deferral Fee from time to time with
respect to the aggregate notional amount of the IBJ Bank Group II Swap
Transactions not otherwise reduced, canceled or terminated.

                (c) Breakage Costs. On the Closing Date, the Borrower shall
irrevocably authorize each Restructure Lender that is an Existing Lender under
the IBJ Facility II to terminate their interest rate swap transactions with IBJ,
and the Borrower shall indemnify each Restructure Lender that is an Existing
Lender under IBJ Facility II for any documented breakage costs, fees, damages or
claims resulting from such termination; provided, however, that each such
Restructure Lender shall use its best efforts to minimize the amount of such
breakage costs, fees, damages and claims, and in addition if such termination
results in payments to be due to any Restructure Lender that is an Existing
Lender under IBJ Facility II, each such Restructure Lender shall ensure that
said payments are received by Borrower.

                                    ARTICLE 6

                              CONDITIONS PRECEDENT

                                    ARTICLE 7

                         REPRESENTATIONS AND WARRANTIES

        SECTION 7.1 REPRESENTATIONS AND WARRANTIES. In order to induce each
Restructure Lender to enter into this Agreement, the Borrower represents and
warrants as follows:

                (a) Organization. The Borrower is duly organized, validly
existing and in good standing under the laws of the state of its formation. The
Borrower is also duly authorized, qualified and licensed in all applicable
jurisdictions, and under all applicable laws, regulations, ordinances or orders
of public authorities, to carry on its business in the locations and in the
manner presently conducted, to the extent that the failure to do so would not
reasonably be expected to have a Material Adverse Effect. All of the
Subsidiaries and Consolidated Subsidiaries of the Borrower and the percentage of
the Borrower's ownership interest therein as of the date of this Agreement are
identified on Schedule 2.

                (b) Authorization. The execution, delivery and performance by
the Borrower of the Restructure Loan Documents are within the Borrower's
corporate powers, have been duly authorized by all necessary corporate action
and do not contravene (i) the Borrower's certificate of incorporation, bylaws or
other organizational documents or (ii) any law or regulation (including
Regulations T, U and X) or any contractual restriction binding on or affecting
the Borrower.

                (c) Governmental Consents. No authorization or approval or other
action by, and no notice to or filing with, any governmental authority or
regulatory body (except routine reports required pursuant to the Securities
Exchange Act of 1934, as amended (if such act is applicable to the Borrower),
which reports will be made in the ordinary course of business) is required for
the due execution, delivery and performance by the Borrower of the Restructure
Loan Documents.

                (d) Validity. The Restructure Loan Documents are the binding
obligations of the Borrower, enforceable in accordance with their respective
terms; except in each case as such enforceability may be limited by bankruptcy,
insolvency, reorganization, liquidation, moratorium or other similar laws of
general application and equitable principles relating to or affecting creditors'
rights.

                (e) Financial Condition. The balance sheet of the Borrower and
its Consolidated Subsidiaries as at the fiscal year ended January 2, 2000, and
the related statements of income, cash flows and stockholders' equity of the
Borrower and its Consolidated Subsidiaries to that date for the fiscal year then
ended, copies of which have been furnished to Restructure Agent and to the
Restructure Lenders, fairly present the financial condition of the Borrower and
its Consolidated Subsidiaries as of such date and the results of the operations
of the Borrower and its Consolidated Subsidiaries for the respective period
ended on such date, all in accordance with GAAP, consistently applied.

                                       23
<PAGE>   29

                (f) Litigation. Except as set forth in the financial statements
delivered on or prior to the date hereof or described on Schedule 4 to this
Agreement, to the best of the Borrower's knowledge after due inquiry there is no
pending or threatened action or proceeding affecting the Borrower or any of its
Consolidated Subsidiaries before any court, governmental agency or arbitrator,
which could reasonably be expected to materially adversely affect the
consolidated financial condition or operations of the Borrower or which could
reasonably be expected to have a material adverse effect on the Borrower's
ability to perform its obligations under the Restructure Loan Documents, having
regard for its other financial obligations (a "Material Adverse Effect").

                (g) Employee Benefit Plans. The Borrower and each of its ERISA
Affiliates is in compliance in all material respects with any applicable
provisions of ERISA and the regulations and published interpretations thereunder
with respect to all Employee Benefit Plans. No Termination Event has occurred or
is reasonably expected to occur with respect to any Pension Plan that would
reasonably be expected to have a Material Adverse Effect.

                (h) Disclosure. No representation or warranty of the Borrower
contained in this Agreement or any other document, certificate or written
statement furnished to Restructure Agent and the Restructure Lenders by or on
behalf of the Borrower for use in connection with the transactions contemplated
by this Agreement contains any untrue statement of a material fact or omits to
state a material fact (known to the Borrower in the case of any document not
furnished by it) necessary in order to make the statements contained herein or
therein not misleading. To the best of the Borrower's knowledge, there is no
fact known to the Borrower (other than matters of a general economic nature)
which materially adversely affects the business, operations, property, assets or
condition (financial or otherwise) of the Borrower and its Consolidated
Subsidiaries, taken as a whole, which has not been disclosed herein or in such
other documents, certificates and statements furnished to Restructure Agent and
the Restructure Lenders for use in connection with the transactions contemplated
hereby.

                (i) Margin Stock. The aggregate value of all margin stock (as
defined in Regulation U) directly or indirectly owned by the Borrower and its
Consolidated Subsidiaries is less than twenty-five percent of the aggregate
value of the Borrower's assets.

                (j) Environmental Matters. Except as set forth in the financial
statements delivered on or prior to the date hereof and except for certain
claims associated with Great Western Chemical, neither the Borrower nor any
Consolidated Subsidiary, nor, to the best of their knowledge, any other person,
has treated, stored, processed, discharged, spilled, or otherwise disposed of
any substance defined as hazardous or toxic by any applicable federal, state or
local rule, regulation, order or directive, or any waste or by-product thereof,
at any real property or any other facility owned, leased or used by the Borrower
or any Consolidated Subsidiary, in violation of any applicable statutes,
regulations, ordinances or directives of any governmental authority or court,
which violations may result in liability to the Borrower or any Consolidated
Subsidiary in an amount for all such violations that could reasonably be
expected to have a Material Adverse Effect; and the unresolved violations set
forth in the financial statements delivered on or prior to the date hereof will
not result in liability to the Borrower or any Consolidated Subsidiary in an
amount for all such unresolved violations that could

                                       24
<PAGE>   30

reasonably be expected to have a Material Adverse Effect. Except as set forth in
the financial statements delivered on or prior to the date hereof, no employee
or other person has ever made a claim or demand against the Borrower or any
Consolidated Subsidiary based on alleged damage to health caused by any such
hazardous or toxic substance or by any waste or by-product thereof in an amount
that could reasonably be expected to have a Material Adverse Effect; and the
unsatisfied claims or demands against the Borrower or any Consolidated
Subsidiary set forth in the financial statements delivered on or prior to the
date hereof will not result in uninsured liability to the Borrower or any
Consolidated Subsidiary or any of their respective officers, employees,
representatives, agents or shareholders in an amount that could reasonably be
expected to have a Material Adverse Effect for all such unsatisfied claims or
demands. Except as set forth in the financial statements delivered on or prior
to the date hereof, neither the Borrower nor any Consolidated Subsidiary has
been charged by any governmental authority with improperly using, handling,
storing, discharging or disposing of any such hazardous or toxic substance or
waste or by-product thereof or with causing or permitting any pollution of any
body of water in an amount that could reasonably be expected to have a Material
Adverse Effect; and the outstanding charges set forth in the financial
statements delivered on or prior to the date hereof will not result in liability
to the Borrower or any Consolidated Subsidiary or any of their respective
officers, employees, representatives, agents or shareholders in an amount that
could reasonably be expected to have a Material Adverse Effect for all such
outstanding charges.

                (k) Employee Matters. There is no strike or work stoppage in
existence or, to the best of the Borrower's knowledge after due inquiry,
threatened involving the Borrower or its Consolidated Subsidiaries that would
reasonably be expected to have a Material Adverse Effect.

                (l) Status of Dastek, Inc., Dastek (M) and DHC. Neither Dastek,
Inc. nor Dastek (M) is an active operating business. To the best knowledge of
the Borrower after due inquiry, none of Dastek, Inc., Dastek (M) or DHC have any
material outstanding liabilities in favor of any Persons that are not affiliated
with the DHC joint-venture.

                (m) Year 2000 Compliance. The Borrower has completed a review
and assessment of the applicable areas of its and each of its Consolidated
Subsidiaries' businesses and operations that could be materially adversely
affected by the "Year 2000" problem (that is, the risk that computer
applications used by the Borrower or any of its Consolidated Subsidiaries may be
unable to recognize and perform properly date-sensitive functions involving
certain dates prior to and any date after December 31, 1999). Based upon the
foregoing, the Borrower developed a plan and timetable to take at the
appropriate time all steps the Borrower considers reasonably necessary to ensure
that all computer applications that are necessary to its or any of its
Consolidated Subsidiaries' businesses and operations are able to perform
properly date-sensitive functions for all dates before and after January 1,
2000, except to the extent that any such Year 2000 non-compliance would not
reasonably be expected to have a Material Adverse Effect. In connection
therewith, the Borrower believes it has committed adequate resources to support
its Year 2000 plan for itself and its Consolidated Subsidiaries.

Consolidated Subsidiaries to exercise, all due diligence in order to comply with
the requirements of all applicable laws, rules, regulations and orders of any
governmental authority, including, without limitation, all environmental laws,
rules, regulations and orders, noncompliance with which would have a Material
Adverse Effect.

                (h) Proceeds of Assets and Capital Raising Events. The Borrower

liability to include, without limitation, any material liability to the PBGC, or

                        (6) As used in this subsection 9.1(h), the term
"accumulated funding deficiency" has the meaning specified in Section 412 of the
Internal Revenue Code, and the terms "actuarial present value" and "benefit
liabilities" have the meanings specified in Section 4001 of ERISA; or

                                       35
<PAGE>   41

                (i) There shall be instituted against the Borrower, or any of
its Consolidated Subsidiaries, any proceeding for which forfeiture (not paid or
seventy-five percent covered by insurance or the third party indemnity of a
solvent indemnitor) of any property equal to or greater than $5,000,000.00 is a
potential penalty and such proceeding shall not have been vacated or discharged
within thirty (30) days of its institution; or

                (j) The Borrower shall fail to observe any term, covenant,
representation, warranty or other provision contained in the Subordinated

become due and payable, and (ii) upon the occurrence and continuance of any
other Restructure Event of Default, Restructure Agent, at the instruction of the
Majority Restructure Lenders, shall, by notice to the Borrower, declare the
Restructured Loans hereunder, with accrued interest thereon, and all other
amounts owing under this Agreement, the Restructured Notes, and the other
Restructure Loan Documents to be due and payable forthwith, whereupon the same
shall immediately become due and payable. Notwithstanding the foregoing, clause
(ii) rather than clause (i) in this paragraph shall apply in the case of a
proceeding described in clause (f)(ii) or (iii) above against a Consolidated
Subsidiary domiciled outside the United States of America, excluding however,
Komag Malaysia from the application of this sentence (in which case, for
avoidance of doubt, clause (i) shall apply), provided the laws or regulations of
the applicable jurisdiction do not prohibit the Restructure Agent or the
Restructure Lenders from giving to the Borrower or Consolidated Subsidiary an
acceleration notice of the type described in clause (ii) of this paragraph.
Except as expressly provided above in this Section 9.1, presentment, demand,
protest and all other notices of any kind are hereby expressly waived.
Notwithstanding any other provision of this Agreement, including Section 12.2,
notices to the Borrower pursuant to this Section 9.1 may be communicated orally
(including by telephone with a written notice to the Borrower to be subsequently
provided by Restructure Agent) or in writing (including telex or facsimile
transmission). Notwithstanding any other provision of this Agreement, each
Restructure Lender hereby agrees with each other Restructure Lender that no
Restructure Lender shall take any action to protect or enforce its rights
arising out of or relating to this Agreement, any of the Restructured Notes, or
any of the other Restructure Loan Documents (including exercising any rights of
offset) without first obtaining the prior written consent of Majority
Restructure Lenders, it being the agreement of Restructure Agent and Restructure
Lenders that any such action to protect or enforce rights under this Agreement,
any of the Restructured Notes, or any of the other Restructure Loan Documents
shall be taken in concert and at the direction or with the consent of the
Majority Restructure Lenders, and not independently by a single Restructure
Lender.

<PAGE>   42

        SECTION 10.1 RESTRUCTURE AGENT. Fleet is hereby appointed as Restructure
Agent by each of the Restructure Lenders to perform such duties on behalf of
itself and the other Restructure Lenders, and to have such powers, as are set
forth herein and as are reasonably incidental thereto. In performing its
functions and duties under this Agreement, Restructure Agent shall act solely as
agent of the Restructure Lenders and does not assume and shall not be deemed to
have assumed any obligation towards or relationship of agency or trust hereunder
with or for the Borrower. The duties of Restructure Agent shall be mechanical
and administrative in nature; Restructure Agent shall not have by reason of this
Agreement a fiduciary relationship in respect of any Restructure Lender, and
nothing in this Agreement, expressed or implied, is intended to or shall be so
construed as to impose upon Restructure Agent any obligations in respect of this
Agreement, the Restructured Loans, the Restructure Loan Documents or the other
instruments and agreements referred to herein except as expressly set forth
herein or therein.

        SECTION 10.2 DELEGATION OF DUTIES, ETC. Restructure Agent may execute
any of its duties and perform any of its powers hereunder by or through agents
or employees, and shall be entitled to consult with legal counsel and any
accountant or other professional selected by it. Restructure Agent shall not be
responsible for the negligence or misconduct of any agents or attorneys-in-fact
selected by it with reasonable care.

        SECTION 10.3 INDEMNIFICATION. The Restructure Lenders agree to indemnify
Restructure Agent in its capacity as such, to the extent not reimbursed promptly
by the Borrower, pro rata according to their respective Restructured Loans
Percentage, from and against any and all claims, liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by or asserted against Restructure Agent in any way relating to or arising out
of this Agreement or the Restructured Notes or any action taken or omitted to be
taken or suffered in good faith by Restructure Agent hereunder or thereunder;
provided, however, that no Restructure Lender shall be liable for any portion of
any of the foregoing items resulting from the gross negligence or willful
misconduct of Restructure Agent. Without limitation of the foregoing, each
Restructure Lender agrees to reimburse Restructure Agent promptly upon demand
for its pro rata share according to their respective Restructured Loans
Percentage of any out-of-pocket expenses (including reasonable counsel fees and
disbursements) incurred by Restructure Agent in connection with the preparation,
execution, administration or enforcement of, legal advice in respect of rights
or responsibilities under, or amendment, modification or waiver of any provision
of, this Agreement, the Restructured Notes, or the other Restructure Loan
Documents, to the extent that Restructure Agent is not promptly reimbursed for
such expenses by the Borrower.

        SECTION 10.4 EXCULPATORY PROVISIONS.

                (a) Neither Restructure Agent nor any of its predecessors,
officers, directors, employees or agents shall be liable for any action taken or
omitted to be taken or suffered in good faith by it or them hereunder or in
connection herewith, except that Restructure Agent shall be liable for its own
gross negligence or willful misconduct. Restructure Agent and its predecessors
shall not be liable in any manner for the effectiveness, enforceability,
collectibility, genuineness, perfection, validity, sufficiency or the due
execution of this Agreement, the other

                                       37
<PAGE>   43

Restructure Loan Documents or the Restructured Notes or for the due
authorization, authenticity or accuracy of the representations and warranties
herein or in any other certificate, report, notice, consent, opinion, statement
or other document furnished or to be furnished hereunder, and shall be entitled
to rely upon any of the foregoing believed by it to be genuine and correct and
to have been signed and sent or made by the proper Person. Restructure Agent and
its predecessors shall be under no duty or responsibility to the Restructure
Lenders to ascertain or to inquire into the performance or observance by the
Borrower of any of the provisions hereof or of any document executed and
delivered in connection herewith. Each Restructure Lender acknowledges that it
has taken and will continue to take such action and to make such investigation
as it deems necessary to inform itself of the affairs of the Borrower and each
Restructure Lender acknowledges that it had the opportunity to make, has made
and will continue to make its own independent investigation of the credit
worthiness and the business and operations of the Borrower and that, in entering
into this Agreement, and in making its Restructured Loans, it has not relied and
will not rely upon any information or representations furnished or given by
Restructure Agent, its predecessors or any other Restructure Lender. For the
purposes of this Section 10, "predecessors" shall include, without limitation,
each of the agents under the Existing Facilities.

                (b) Each Restructure Lender expressly acknowledges that
Restructure Agent and its predecessors have not made any representations or
warranties to it and that no act taken by Restructure Agent or its predecessors
shall be deemed to constitute any representation or warranty by Restructure
Agent or its predecessors to the Restructure Lenders.

                (c) If Restructure Agent shall request instruction from
Restructure Lenders with respect to any act or action (including the failure to
take an action) in connection with the Restructured Loans under this Agreement,
Restructure Agent shall be entitled to refrain from such act or taking such
action unless and until Restructure Agent shall have received instructions from
all of the Restructure Lenders or the Majority Restructure Lenders, as the case
may be and as required herein. Without prejudice to the generality of the
foregoing, (i) Restructure Agent shall be entitled to rely, and shall be fully
protected in relying, upon any communication, instrument or document believed by
it to be genuine and correct and to have been signed or sent by the proper
Person or Persons, and shall be entitled to rely and shall be protected in
relying on opinions and judgments of attorneys, accountants, experts and other
professional advisors selected by it; and (ii) no Restructure Lender shall have
any right of action whatsoever against Restructure Agent or its predecessors as
a result of Restructure Agent acting or (where so instructed) refraining from
acting under this Agreement with respect to the Restructured Loans in accordance
with the instructions of all of the Restructure Lenders or the Majority
Restructure Lenders, as the case may be.

        SECTION 10.5 KNOWLEDGE OF DEFAULT. It is expressly understood and agreed
that Restructure Agent shall be entitled to assume that no Restructure Event of
Default has occurred and is continuing, unless the officers of Restructure Agent
immediately responsible for matters concerning this Agreement shall have actual
knowledge of such occurrence or shall have been notified in writing by any
Restructure Lender that such Restructure Lender considers that a Restructure
Event of Default has occurred and is continuing and specifying the nature
thereof. In

                                       38
<PAGE>   44

the event that Restructure Agent shall have acquired actual knowledge of any
Restructure Event of Default, it shall promptly give notice thereof to the
Restructure Lenders.

        SECTION 10.6 RESTRUCTURE AGENT IN ITS INDIVIDUAL CAPACITY. With respect
to this Agreement, and all Restructured Loans made by it and any renewals,
extensions or deferrals of the payment thereof and any Restructured Note issued
to or held by it, the Restructure Agent shall have the same rights and powers
hereunder as any Restructure Lender, and may exercise the same as though it were
not Restructure Agent, and the term "Restructure Lender" or "Restructure
Lenders" shall, unless the context otherwise requires, include Restructure Agent
in its individual capacity. Restructure Agent and each of its Restructure Lender
Affiliates may accept deposits from, lend money to and generally engage in any
kind of banking, trust, financial advisory or other business with the Borrower
or any Subsidiary or Consolidated Subsidiary as if it were not performing the
duties specified herein, and may accept fees and other consideration from the
Borrower for services in connection with this Agreement and otherwise without
having to account for the same to the Restructure Lenders.

        SECTION 10.7 PAYEE OF RESTRUCTURED NOTES TREATED AS OWNER. Restructure
Agent may deem and treat the payee of any Restructured Note as the owner thereof
for all purposes hereof unless and until an Assignment Agreement shall have been
lodged with Restructure Agent as provided in Section 12.6. Any request,
authority or consent of any person or entity who, at the time of making such
request or giving such authority or consent, is the holder of any such
Restructured Note shall be conclusive and binding on any subsequent holder,
transferee or assignee of that Restructured Note or of any Restructured Note or
Restructured Notes issued in exchange therefor.

        SECTION 10.8 RESIGNATION OF RESTRUCTURE AGENT. If at any time
Restructure Agent deems it advisable, in its sole discretion, it may submit to
each of the Restructure Lenders and the Borrower a written notification of its
resignation as Restructure Agent under this Agreement, such resignation (subject
to the further provisions of this Section 10.8) to be effective on the thirtieth
day after the date of such notice. Upon any such resignation, the Majority
Restructure Lenders, subject to the prior written consent of the Borrower if no
Restructure Event of Default shall have occurred and be continuing (which
consent shall not be unreasonably withheld), shall have the right to appoint a
successor Restructure Agent. If no successor Restructure Agent shall have been
so appointed by the Majority Restructure Lenders and accepted such appointment
within thirty (30) days after the retiring Restructure Agent's giving of notice
of resignation, then the retiring Restructure Agent may, on behalf of the
Restructure Lenders, appoint a successor Restructure Agent, which successor
Restructure Agent shall be either a Restructure Lender or if none of the
Restructure Lenders is willing to serve as successor Restructure Agent, a bank
having combined capital and surplus of at least $100,000,000.00. Any such
appointment of a successor Restructure Agent shall be subject to the prior
written approval of the Borrower if no Restructure Event of Default shall have
occurred and be continuing (which approval shall not be unreasonably withheld).
Upon the acceptance of any appointment as Restructure Agent hereunder by a
successor Restructure Agent, such successor Restructure Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Restructure Agent, and the retiring Restructure Agent shall be
discharged from its duties and obligations under this

                                       39
<PAGE>   45
Agreement. The Borrower and the Restructure Lenders shall execute such documents
as shall be necessary to effect such appointment. After any retiring Restructure
Agent's resignation hereunder as Restructure Agent, the provisions of this
Article shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Restructure Agent under this Agreement and the
Restructured Notes. Notwithstanding the foregoing provisions of this Section
10.8, if at any time there shall not be a duly appointed and acting Restructure
Agent, the Borrower agrees to make each payment due hereunder and under the
Restructured Loans directly to the Restructure Lenders entitled thereto during
such time.

                                   ARTICLE 11

                            CONVERSION LENDER OPTION

                SECTION 11.1 ELECTION. Notwithstanding anything to the contrary
in this Agreement or in any other Restructure Loan Document, any Restructure
Lender may convert its Restructured Loan (including, for purposes of this
Article 11 and for the avoidance of doubt, Existing Loan) into a convertible
Debt Instrument subject to the following terms and conditions: (i) for each
Restructured Loan owned by such Restructure Lender on the Closing Date, by
irrevocable written notice delivered by the Restructure Lender to the
Restructure Agent that it shall convert such Restructured Loan to a convertible
Debt Instrument on terms and conditions set forth in the Securities Purchase
Agreement, the Convertible Note and the Registration Rights Agreement
(collectively, the "Conversion Documents") annexed as Exhibit D to this
Agreement, which notice shall be delivered concurrently with such Restructure
Lender's execution of this Agreement (each, a "Closing Date Conversion Notice");
and (ii) for each Restructured Loan that was not the subject of a Closing Date
Conversion Notice, by irrevocable written notice delivered by the Restructure
Lender to the Restructure Agent that it shall convert, subject to the Borrower's
consent, such Restructured Loan to a convertible Debt Instrument on terms and
conditions that are similar in all material respects to those set forth in
Exhibit D (collectively, the "Post-Closing Conversion Documents"), which notice
shall be delivered concurrently with such Restructure Lender's notice to
Borrower of its election to purchase such convertible Debt Instruments (each, a
"Post-Closing Conversion Notice").

                SECTION 11.2 CONVERSION LENDER. Each Restructure Lender, solely
with respect to its Restructured Loan for which irrevocable notice has been
delivered to Restructure Agent as provided above, shall be deemed a "Conversion
Lender" for purposes of this Article 11.

                SECTION 11.3 CONVERSION DATE RIGHTS. With respect to each
Closing Date Conversion Notice or Post-Closing Date Conversion Notice, such
Conversion Lender shall, from and after the effective closing date specified in
the Conversion Documents or the Post-Closing Conversion Documents, as applicable
(the "Conversion Date"): (i) relinquish all rights and benefits under this
Agreement and any other Restructure Loan Document arising or accruing from and
after the applicable Conversion Date, and (ii) such Conversion Lender shall be
deemed released from all obligations under this Agreement and the other
Restructure Loan Documents arising or accruing from and after the applicable
Conversion Date, including, without limitation, any such obligations under
Sections 4.2(i), 9.l and 10.3 hereof.

                                       40

<PAGE>   46

In addition, Restructure Agent consent will not be necessary for the assignment
by any Restructure Lender of its Restructured Loan subsequent to the Closing
Date provided all of the other terms and conditions of Section 12.6 hereof have
been satisfied and further provided that the assignee of the Restructure Lender
irrevocably agrees at the time of such assignment to become a Conversion Lender
with respect to the Restructured Loan it has acquired.

For the avoidance of doubt, the rights and benefits relinquished by any
Conversion Lender in subsection (i) of this Section 11.3 shall include any
payments of principal, interest, fees, or expenses and any voting rights under
this Agreement or any other Restructure Loan Document, to the extent the same
arise or accrue after the applicable Conversion Date; provided, however, the
Restructure Fee payable under Section 4.1(b) hereof, the $15,000,000.00
mandatory repayment of the principal amount of the Restructured Loan as set
forth in the first sentence of Section 4.2(a) hereof, and all rights under the
Warrant Agreement, shall be deemed to arise on the Closing Date for the ratable
benefit of the Restructure Lenders as of the Closing Date.

                                   ARTICLE 12

                                  MISCELLANEOUS

        SECTION 12.1 AMENDMENTS, ETC.

                (a) No amendment or waiver of any provision of the Restructure
Loan Documents, nor consent to any departure by the Borrower therefrom, shall in
any event be effective unless the same shall be in writing and signed by the
Majority Restructure Lenders, and then such waiver or consent shall be effective
only in the specific instance and for the specific purpose for which given;
provided, however, that, without the written consent of all of the Restructure
Lenders, no amendment, waiver or consent shall do any of the following:

                (b) extend the Restructure Maturity Date, or subject the
Restructure Lenders to any additional obligations;

                (c) reduce the principal of, or interest on, the Restructured
Loans or any fee or other amount payable to the Restructure Lenders hereunder;

                (d) postpone any date fixed for any payment in respect of
principal of, or interest on, the Restructured Loans or any fee or other amount
payable to the Restructure Lenders hereunder;

                (e) change the definition of "Majority Restructure Lenders" or
any definition or provision of this Agreement requiring the approval of Majority
Restructure Lenders or some other specified amount of Restructure Lenders;

                (f) amend the provisions of Section 4.2(i); or

                (g) amend the provisions of this Section 12.1; and

                                       41
<PAGE>   47

provided, further, however, that no amendment, waiver or consent shall, unless
in writing and signed by Restructure Agent in addition to the Restructure
Lenders required hereinabove to take such action, affect the rights, obligations
or duties of Restructure Agent under this Agreement or any other Restructure
Loan Document.

        SECTION 12.2 NOTICES, ETC. Except as otherwise set forth in this
Agreement, all notices and other communications provided for hereunder shall be
in writing (including telegraphic, telex or facsimile communication) and mailed
or telegraphed or telexed or sent by facsimile or delivered, if to the Borrower,
at the Borrower's address set forth on the signature page hereof; and if to
Restructure Agent and/or the Restructure Lenders, at their respective addresses
set forth on the signature page hereof; or, as to each party, at such other
address as shall be designated by such party in a written notice to the other
parties. All such notices and communications shall be effective when deposited
in the mails, delivered to the telegraph company, sent by telex or sent by
facsimile, respectively, except that notices and communications to Restructure
Agent and the Restructure Lenders pursuant to Articles 4, 8 or 9 shall not be
effective until received by Restructure Agent and the Restructure Lenders.

        SECTION 12.3 RIGHT OF SETOFF. Upon and after the occurrence of any
Restructure Event of Default, the Restructure Lenders are hereby authorized by
the Borrower, at any time, after having first obtained the written consent of
Restructure Agent, and from time to time, without prior notice, (a) to set off
against, and to appropriate and apply to the payment of, the obligations and
liabilities of the Borrower under the Restructure Loan Documents (whether
matured or unmatured, fixed or contingent or liquidated or unliquidated) any and
all amounts owing by the Restructure Lenders to the Borrower (whether payable in
Dollars or any other currency, whether matured or unmatured, and, in the case of
deposits, whether general or special, time or demand and however evidenced) and
(b) pending any such action, to the extent necessary, to hold such amounts as
collateral to secure such obligations and liabilities and to return as unpaid
for insufficient funds any and all checks and other items drawn against any
deposits so held as the Restructure Lenders in their sole discretion may elect.
The Restructure Lenders agree promptly to notify the Borrower after any such
setoff and application made by the Restructure Lenders. Upon and during the
continuance of any Restructure Event of Default and after having first obtained
the written consent of Restructure Agent (which consent shall not unreasonably
be withheld), the Restructure Lenders are authorized to debit any account
maintained with them by the Borrower for any amount of principal, interest or
fees which are then due and owing to the Restructure Lenders by the Borrower.

        SECTION 12.4 NO WAIVER; REMEDIES. The Restructure Lenders' waiver of the
Existing Defaults or of any of the terms and/or conditions of the Restructure
Loan Documents shall not be deemed a waiver of any such other or future default.
No failure on the part of Restructure Agent, on behalf of itself or the
Restructure Lenders, or the Restructure Lenders to exercise, and no delay in
exercising, any right under any of the Restructure Loan Documents shall operate
as a waiver thereof; nor shall any single or partial exercise of any right under
any of the Restructure Loan Documents preclude any other or further exercise
thereof or the exercise of any other right. The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

                                       42
<PAGE>   48

        SECTION 12.5 COSTS AND EXPENSES. The Borrower shall, no later than
thirty (30) days after written notice thereof, reimburse Restructure Agent and
the agents of the Existing Facilities for all reasonable fees, costs and
expenses, including the fees, costs and expenses of counsel or other advisors
(including environmental and management consultants and appraisers) for advice,
assistance, or other representation in connection with:

                (a)     any amendment, modification or waiver of, or consent
                        with respect to, any of the Restructure Loan Documents
                        or advice in connection with the administration of the
                        Restructure Loans made pursuant hereto or its rights
                        hereunder or thereunder;

                (b)     any litigation, contest, dispute, suit, proceeding or
                        action (whether instituted by either the Restructure
                        Agent, any Restructure Lender, the Borrower or any other
                        Person) in any way relating to any of the Restructure
                        Loan Documents or any other agreement to be executed or
                        delivered in connection therewith or herewith, whether
                        as party, witness, or otherwise, including any
                        litigation, contest, dispute, suit, case, proceeding or
                        action, and any appeal or review thereof, in connection
                        with a case commenced by or against the Borrower or any
                        other Person that may be obligated to either the
                        Restructure Agent or any Restructure Lender by virtue of
                        the Restructure Loan Documents, including any such
                        litigation, contest, dispute, suit, proceeding or action
                        arising in connection with any work-out or restructuring
                        of the Restructured Loans during the pendency of one or
                        more Restructure Events of Default;

                (c)     any attempt to enforce any remedies of either the
                        Restructure Agent or any Restructure Lender against the
                        Borrower or any other Person that may be obligated to
                        either the Restructure Agent or any Restructure Lender
                        by virtue of any of the Restructure Loan Documents,
                        including any such attempt to enforce any such remedies
                        in the course of any work-out or restructuring of the
                        Restructured Loans during the pendency of one or more
                        Restructure Events of Default;

                (d)     any work-out or restructuring of the Restructured Loans
                        during the pendency of one or more Restructure Events of
                        Default; and

                (e)     efforts to (i) monitor the Restructured Loans, (ii)
                        evaluate, observe or assess the Borrower or its affairs,
                        and (iii) verify, protect, evaluate, assess, appraise,
                        collect, sell, liquidate or otherwise dispose of any
                        property of the Borrower, including, as to each of
                        clauses (a) through (d) of this Section 12.5, all
                        attorneys' and other professional and service providers'
                        fees arising from such services, including those in
                        connection with any appellate proceedings; and all
                        expenses, costs, charges and other fees incurred by such
                        counsel and others in any way or respect arising in
                        connection with or relating to any of the events or
                        actions described in this

                                       43
<PAGE>   49

                        Section 12.5 shall be payable, on demand, by the
                        Borrower to the Restructure Agent and Restructure
                        Lenders.

        Without limiting the generality of the foregoing Section 12.5, such
expenses, costs, charges and fees may include: fees, costs and expenses of
accountants, environmental advisors, appraisers, investment bankers, management
and other consultants and paralegals; court costs and expenses; photocopying and
duplication expenses; court reporter fees, costs and expenses; long distance
telephone charges; air express charges; telegram or telecopy charges;
secretarial overtime charges; and expenses for travel, lodging and food paid or
incurred in connection with the performance of such legal or other advisory
services. After the Closing Date, the Restructure Agent and the agents of the
Existing Facilities will use their best efforts to retain professional advisors
jointly rather than retaining separate counsel, consultants and other
professional advisors. Notwithstanding the foregoing Section 12.5, on the
Closing Date, and thereafter on a quarterly basis, Crossroads shall provide the
Borrower, Restructure Agent and Restructure Lenders with a written budget on a
quarterly basis. So long as (a) no Restructure Event of Default shall have
occurred and (b) the Restructure Agent, in the exercise of its reasonable
discretion, does not believe that there is a reasonable likelihood that a
Restructure Event of Default will occur, the Borrower shall not be obligated to
reimburse Crossroads for its fees and expenses for any quarter that exceed the
budgeted amounts set forth in the applicable budget by more than ten percent
unless Crossroads shall have received the written consent of the Restructure
Agent and the Borrower (which consent shall not be unreasonably withheld). In
the event the Borrower does not pay timely any expenses, fees, charges or costs
due pursuant to this Section 12.5, interest shall accrue on such unpaid amount
at the rate of ten percent per annum until paid in full.

        SECTION 12.6 ASSIGNMENTS; PARTICIPATIONS.

                (a) Any Restructure Lender may assign with the consent of the
Restructure Agent (which shall not unreasonably be withheld or delayed) all or
any portion of its Restructured Loan and Restructured Note to any Person except
a Person primarily employed or engaged in any aspect of the computer hardware or
peripheral business (a "Prohibited Assignee"). If the assignee of any
Restructured Loan or Restructured Note is a broker or other intermediary, the
Restructure Lender making the assignment shall be required to obtain, prior to
such assignment, a representation from such Person that the Restructured Loan
and Restructured Note will not be beneficially owned by any Prohibited Assignee.
For purposes of this Agreement, beneficial ownership shall not include an
investment in a fund which is independently managed and formed with a primary
purpose of purchasing or holding loans. The Restructure Agent and each
Restructure Lender, including the Restructure Lender making the assignment,
shall be entitled to rely upon such representation without any further
investigation or diligence. The minimum amount of any Restructured Loan which
may be assigned is the lesser of $5,000,000.00 or the Restructure Lenders'
entire Restructured Loan. Upon execution and delivery of an assignment agreement
substantially in the form of Exhibit B ("Assignment Agreement"), from and after
the effective date specified in such Assignment Agreement (X) the assignee
thereunder shall be a party hereto and, to the extent that rights and
obligations hereunder have been assigned to it pursuant to such Assignment
Agreement, have the rights and obligations of a Restructure Lender hereunder and
(Y) the Restructure Lender assignor thereunder shall, to

                                       44
<PAGE>   50

the extent that rights and obligations hereunder have been assigned by it
pursuant to such Assignment Agreement, relinquish its rights and be released
from its obligations under this Agreement, except with respect to those
obligations set forth in the Nondisclosure Agreement which the assignor had
previously executed, and, in the case of an Assignment Agreement covering all or
the remaining portion of an assigning Restructure Lender's rights and
obligations under this Agreement, such Restructure Lender shall cease to be a
party hereto. Each Restructure Lender's Restructure Loans Percentage hereunder
shall be modified to reflect the Restructured Loan of such assignor and assignee
(and Schedule 1 shall be deemed amended and revised to reflect such
modification), and, if any such assignment occurs while any Restructured Loan is
outstanding, new Restructured Notes shall, if requested by the assignor
Restructure Lender or such assignee, upon the surrender of the assigning
Restructure Lender's Restructured Notes, be issued to such assignee and to the
assigning Restructure Lender as necessary to reflect the new Restructured Loans
Percentage of the assigning Restructure Lender and of its assignee. Any
assigning Restructure Lender shall pay a $2,500.00 fee in connection with the
effectiveness of any assignment it makes to the Restructure Agent. The
Restructure Agent shall give the Borrower written notice of any assignment
disclosed to it within two business days after such disclosure.

For the avoidance of doubt, any Restructure Lender may assign, but is not
required to assign, its rights with respect to the Warrant Agreement to any
assignee of the Restructured Loan of such Restructure Lender.

                (b) Each Restructure Lender may sell, negotiate or grant
participations to any Person in all or part of the obligations of the Borrower
outstanding under the Restructure Loan Documents, without notice to or the
approval of Restructure Agent, Restructure Lenders, or the Borrower; provided,
however, that any such sale, negotiation or participation shall be in compliance
with the applicable federal and state securities laws. No Restructure Lender
shall transfer or grant any participating interest under which the participant
shall have rights to approve any amendment to, or any consent or waiver with
respect to, this Agreement or any other Restructure Loan Document, except to the
extent such amendment, consent or waiver would require unanimous consent as
described in the first proviso to Section 12.1. No participant shall constitute
a "Restructure Lender" under any Restructure Loan Document, and the Borrower
shall continue to deal solely and directly with Restructure Agent and the
Restructure Lenders. The Restructure Agent shall give the Borrower written
notice of any participation disclosed to it in writing within two (2) business
days after receipt of such disclosure.

                (c) Each Restructure Lender may disclose to any proposed
approved assignee or participant which is not a Prohibited Assignee any
information relating to the Borrower or any of its Consolidated Subsidiaries;
provided, however, that prior to such disclosure such proposed assignee or
participant shall have executed a Nondisclosure Agreement substantially in the
form of Exhibit C. The applicable Restructure Lender shall provide the Borrower
with a copy of the Nondisclosure Agreement executed by any proposed assignee or
participant within two business days after such agreement has been executed;
provided, however, the failure to so provide such Nondisclosure Agreement shall
not constitute a default under, or breach of, this Agreement.

                                       45
<PAGE>   51

                (d) Notwithstanding the foregoing provisions of this Section
12.6, any Restructure Lender may at any time pledge or assign all or any portion
of such Restructure Lender's rights under this Agreement or any Restructure Loan
Document to a Federal Reserve bank; provided, however, that no such pledge or
assignment shall release such Restructure Lender from its obligations hereunder
or pursuant to any Restructure Loan Document.

                SECTION 12.7 EFFECTIVENESS; BINDING EFFECT; GOVERNING LAW. This
Agreement is being executed on the date hereof by the Borrower, the Restructure
Lenders and Fleet (in its capacities as Restructure Agent and Restructure
Lender) and is binding on and effective against each such party as of the date
hereof. This Agreement shall become effective when it shall have been executed
by the Borrower, Restructure Agent and the Restructure Lenders and thereafter
shall be binding upon and inure to the benefit of the Borrower, Restructure
Agent and the Restructure Lenders and their respective permitted successors and
assigns, except that the Borrower shall not have the right to assign its rights
hereunder or any interest herein without the prior written consent of
Restructure Agent and the Restructure Lenders. THIS AGREEMENT, THE RESTRUCTURED
NOTES AND THE OTHER RESTRUCTURE LOAN DOCUMENTS SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF CALIFORNIA WITHOUT GIVING
EFFECT TO ITS CHOICE OF LAW DOCTRINE.

        SECTION 12.8 CONSENT TO JURISDICTION; VENUE; AGENT FOR SERVICE OF
PROCESS. All judicial proceedings brought against the Borrower with respect to
this Agreement and the Restructure Loan Documents may be brought in any state or
federal court of competent jurisdiction in the County of San Francisco in the
State of California, and by execution and delivery of this Agreement, the
Borrower accepts for itself and in connection with its properties, generally and
unconditionally, the nonexclusive jurisdiction of the aforesaid courts, and
irrevocably agrees to be bound by any judgment rendered thereby in connection
with this Agreement. The Borrower irrevocably waives any right it may have to
assert the doctrine of forum non conveniens or to object to venue to the extent
any proceeding is brought in accordance with this Section 12.8. The Borrower
designates and appoints the Borrower's Chief Financial Officer, from time to
time, Komag Incorporated, 1710 Automation Parkway, San Jose, California,
95131-1873, and such other Persons as may hereafter be selected by the Borrower
irrevocably agreeing in writing to so serve as its agent to receive on its
behalf service of all process in any such proceedings in any such court, such
service being hereby acknowledged by the Borrower to be effective and binding
service in every respect. A copy of any such process so served shall be mailed
by registered mail to the Borrower at its address provided in the applicable
signature page hereto, except that unless otherwise provided by applicable law,
any failure to mail such copy shall not affect the validity of service of
process. If any agent appointed by the Borrower refuses to accept service, the
Borrower hereby agrees that service upon it by mail shall constitute sufficient
notice. Nothing herein shall affect the right to serve process in any other
manner permitted by law or shall limit the right of Restructure Agent, on behalf
of itself and the Restructure Lenders, to bring proceedings against the Borrower
in courts of any jurisdiction.

        SECTION 12.9 ENTIRE AGREEMENT. This Agreement with Exhibits and
Schedules and the other Restructure Loan Documents embody the entire agreement
and understanding

                                       46
<PAGE>   52

between the parties hereto and supersedes all prior agreements and
understandings relating to the subject matter hereof.

        SECTION 12.10 SEVERABILITY OF PROVISIONS. In case any one or more of the
provisions contained in this Agreement should be invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby.

        SECTION 12.11 EXECUTION IN COUNTERPARTS. This Agreement may be executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same agreement.

        SECTION 12.12 SURVIVAL OF CERTAIN AGREEMENTS. Notwithstanding anything
in this Agreement or implied by law to the contrary, the agreement of the
Borrower set forth in Section 5.6 and the agreements of the Restructure Lenders
set forth in Sections 10.2, 10.3, and 10.4 (as well as any obligations under any
Nondisclosure Agreements) shall survive the payment of the Restructure Loans and
the Restructured Notes and the termination of this Agreement. Notwithstanding
anything in this Agreement to the contrary, the agreement of the Borrower set
forth in Sections 5.5, and 5.7 of this Agreement shall survive for one hundred
and eighty (180) days from the date of the payment of the Restructured Loans and
Restructured Notes.

        SECTION 12.13 REVIVAL CLAUSE. If the incurring of any debt, the payment
of money or transfer of property under the Existing Facilities or the
Restructure Loan Documents made to Restructure Agent or any Restructure Lender
by or on behalf of the Borrower should for any reason, in whole or in part,
subsequently be declared to be "fraudulent" or preferential or otherwise be
recoverable (collectively, "Voidable Transfers") within the meaning of any state
or federal law governing creditors' rights including the Bankruptcy Code, and
Restructure Agent or any Restructure Lender is required to repay or restore any
such Voidable Transfers or portion thereof or, upon the advice of its counsel is
advised to do so, then, as to any such Voidable Transfer or the amount repaid or
restored (including all reasonable costs, expenses and attorneys' fees of
Restructure Agent and Restructure Lender related thereto), the liability of the
Borrower under the applicable facility shall automatically be revived,
reinstated and restored as though such Voidable Transfer had never been made.

        SECTION 12.14 RELEASE OF ALL CLAIMS.

                (a) The Borrower on behalf of itself and each of its successors
and assigns hereby forever and irrevocably releases Restructure Agent, each
Restructure Lender and each of their respective officers, representatives,
agents, attorneys, employees, financial consultants, predecessors, successors
and assigns, from the Claims, whether such Claims are known or unknown,
contingent or absolute and howsoever arising.

                (b) The Borrower has been advised by counsel with respect to the
release contained herein. Upon advice of such counsel, the Borrower hereby
waives and relinquishes all

                                       47
<PAGE>   53

of the rights and benefits which it has, or may have, with respect to the Claims
released under Section 1542 of the California Civil Code or any other similar
statute.

                (c) The Borrower is familiar with and waives the provisions of
Section 1542 of the California Civil Code which provide as follows:

                A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR
                DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF
                EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE
                MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.

        SECTION 12.15 ADDITIONAL ASSURANCES. The Borrower agrees that it will
execute such other documents and instruments and perform such other acts as may
reasonably be required by Restructure Agent and Restructure Lenders to carry out
and effectuate the purpose and intent of this Agreement.

        SECTION 12.16 CONFIDENTIALITY. Notwithstanding any other provision of
this Agreement, each of the Borrower, the Restructure Agent, the Restructure
Lenders and Crossroads shall be bound by the provisions of the Nondisclosure
Agreement attached hereto as Exhibit C.

                            [Signature pages follow]

 --------------------

                FOR VALUE RECEIVED, KOMAG, INCORPORATED (the "Borrower"),

principal and interest shall be due and payable in full on the Restructure
Maturity Date as defined in the Restructure Agreement referred to below.

                The Borrower also promises to pay interest on the unpaid
principal amount hereof from the date hereof until paid at the rates and at the

Restructure Agreement referred to below.

All payments and prepayments of principal and all payments of interest, fees and
other amounts payable in respect of this Restructured Note shall be made by the

SUCH OTHER PLACE AS IT SHALL DESIGNATE IN WRITING FOR SUCH PURPOSE IN ACCORDANCE
WITH THE TERMS OF THE RESTRUCTURE AGREEMENT REFERRED TO BELOW in immediately
available UNITED STATES DOLLARS, on or before 12:00 p.m. (Eastern time) on the
due date thereof, WITHOUT COUNTERCLAIM OR SETOFF AND FREE AND CLEAR OF, AND
WITHOUT ANY DEDUCTION OR WITHHOLDING FOR, ANY TAXES OR OTHER PAYMENTS. Until
notified of the transfer of this Restructured Note, the Borrower shall be
entitled to deem the Restructure Lender or such person who has been so
identified by the transferor in writing to the Borrower as the holder of this
Restructured Note, as the owner and holder of this Restructured Note. Each of
the Restructure Lender and any subsequent holder of this Restructured Note
agrees that before disposing of this Restructured Note or any part hereof it
will make a notation hereon of all principal payments previously made hereunder
and of the date to which interest hereon has been paid on the schedule attached
hereto, if any; provided, however, that the failure to make notation of any
payment made on this Restructured Note shall not limit or otherwise affect the
obligation of the Borrower hereunder with respect to payments of principal or
interest on this Restructured Note.

                This Restructured Note is referred to in, and is entitled to the
benefits of, the Loan Restructure Agreement dated as of May 25, 2000 (as

from such Restructured Loan being evidenced by this Restructured Note, and (ii)
contains provisions for acceleration of the maturity hereof upon the happening
of certain stated events and also for prepayments on account of principal hereof
prior to the maturity hereof upon the terms and conditions therein specified.

                The terms of this Restructured Note are subject to amendment
only in the manner provided in the Restructure Agreement.

                No reference herein to the Restructure Agreement and no

respective times, and in the currency herein prescribed.

entirety any promissory notes delivered pursuant to the Existing Facilities (as
defined in the Restructure Agreement) in favor of the Restructure Lender.

                                   LITIGATION

The company has received a letter on behalf of Magnetic Memory Development, LLC
("MMD") referencing a number of patents issued on alleged inventions by Virgil
Hedgcoth (U.S. Patent Nos. 4,735,840, 4,894,133, 5,020,747, 5,316,864, and
5,636,970). MMD is the purported owner of these patents. MMD has offered to
grant a license to the Company under the patents listed, and the Company and MMD
are currently in discussions regarding a license. However, the Company can give
no assurance regarding whether the terms of the license will be agreed upon,
whether this matter will lead to litigation, the probable outcome of any
litigation, if litigation is commenced, or the amount of damages awarded against
the Company should such litigation occur and be determined unfavorably to the
Company.

        Asahi Glass Company, Ltd. ("Asahi"), has asserted that it has an
exclusive right to Komag's intellectual property relating to glass substrates
under a technical cooperation agreement between Komag and Asahi. Komag disagrees
with Asahi's position. Komag and Asahi are currently in discussions regarding
this issue.<PAGE>   1

        WHEREAS:

        A. The Company and each Buyer are executing and delivering this
Agreement in reliance upon the exemption from securities registration afforded
by Rule 506 of Regulation D ("REGULATION D") as promulgated by the United States
Securities and Exchange Commission (the "SEC") under the Securities Act of 1933,
as amended (the "1933 ACT");

Notes such Buyer will purchase at such Additional Closing, which amount shall
not exceed when aggregated with the principal amount of all Additional Notes
purchased by such Buyer such Buyer's pro rata portion of $35,700,000 (pro rata
based on the principal amount of Initial Notes purchased by each Buyer at the
Initial Closing (as defined below) compared to the principal amount of all
Initial Notes purchased by all Buyers), (ii) the aggregate Purchase Price for
the Additional Notes and (iii) the Additional Closing Date for such Additional
Closing. The Additional Closing shall occur on an Additional Closing Date at the
offices of Katten Muchin Zavis, 525 West Monroe Street, Suite 1600, Chicago,

                d. Form of Payment. On each of the Closing Dates, (i) each Buyer
shall pay the Purchase Price to the Company for the Notes to be issued and sold
to such Buyer at such Closing, by delivering evidence of indebtedness of the

behalf of the Company and registered in the name of such Buyer or its designee.

        2. BUYER'S REPRESENTATIONS AND WARRANTIES.

                Each Buyer represents and warrants with respect to only itself
that:

                a. Investment Purpose. Such Buyer is acquiring the Notes and,
upon conversion of the Notes, will acquire the Conversion Shares then issuable
(the Notes and the Conversion Shares collectively are referred to herein as the
"SECURITIES"), for its own account and not with a present view towards, or for
resale in connection with, the public sale or distribution thereof, except
pursuant to sales registered or exempted under the 1933 Act; provided, however,
that by making the representations herein, such Buyer does not agree to hold any
of the Securities for any minimum or other specific term and reserves the right
to dispose of the Securities at any time in accordance with or pursuant to a
registration statement or an exemption under the 1933 Act.

                b. Accredited Investor Status. Such Buyer is an "accredited
investor" as that term is defined in Rule 501(a)(3) of Regulation D.

                c. Reliance on Exemptions. Such Buyer understands that the
Securities are being offered and sold to it in reliance on specific exemptions
from the registration requirements of the United States federal and state
securities laws and that the Company is relying in part upon the truth and
accuracy of, and such Buyer's compliance with, the representations, warranties,
agreements, acknowledgments and understandings of such Buyer set forth herein in
order to determine the availability of such exemptions and the eligibility of
such Buyer to acquire the Securities.

                                      -3-
<PAGE>   4

                d. Information. Such Buyer and its advisors, if any, have been
furnished with all materials relating to the business, finances and operations
of the Company and materials relating to the offer and sale of the Securities
which have been requested by such Buyer. Such Buyer and its advisors, if any,
have been afforded the opportunity to ask questions of the Company. Neither such
inquiries nor any other due diligence investigations conducted by such Buyer or
its advisors, if any, or its representatives shall modify, amend or affect such
Buyer's right to rely on the Company's representations and warranties contained
in Sections 3 and 9(m) below. Such Buyer understands that its investment in the
Securities involves a high degree of risk. Such Buyer has sought such
accounting, legal and tax advice as it has considered necessary to make an
informed investment decision with respect to its acquisition of the Securities.

                e. No Governmental Review. Such Buyer understands that no United
States federal or state agency or any other government or governmental agency
has passed on or made any recommendation or endorsement of the Securities or the
fairness or suitability of the investment in the Securities nor have such
authorities passed upon or endorsed the merits of the offering of the
Securities.

                f. Transfer or Resale. Such Buyer understands that except as
provided in the Registration Rights Agreement: (i) the Securities have not been
and are not being registered under the 1933 Act or any state securities laws,
and may not be offered for sale, sold, assigned or transferred unless (A)
subsequently registered thereunder, (B) such Buyer shall have delivered to the
Company an opinion of counsel, reasonably acceptable to the Company, to the
effect that such Securities to be sold, assigned or transferred may be sold,
assigned or transferred pursuant to an exemption from such registration, or (C)
such Buyer provides the Company with reasonable assurance that such Securities
can be sold, assigned or transferred pursuant to Rule 144 promulgated under the
1933 Act, as amended, (or a successor rule thereto) ("RULE 144"); (ii) any sale
of the Securities made in reliance on Rule 144 may be made only in accordance
with the terms of Rule 144 and further, if Rule 144 is not applicable, any
resale of the Securities under circumstances in which the seller (or the person
through whom the sale is made) may be deemed to be an underwriter (as that term
is defined in the 1933 Act) may require compliance with some other exemption
under the 1933 Act or the rules and regulations of the SEC thereunder; and (iii)
neither the Company nor any other person is under any obligation to register the
Securities under the 1933 Act or any state securities laws or to comply with the
terms and conditions of any exemption thereunder. Notwithstanding the foregoing,
the Securities may be pledged in connection with a bona fide margin account or
other loan secured by the Securities.

                g. Legends. Such Buyer understands that the certificates or
other instruments representing the Notes and, until such time as the sale of the
Conversion Shares have been registered under the 1933 Act as contemplated by the
Registration Rights Agreement, the stock certificates representing the
Conversion Shares, except as set forth below, shall bear a restrictive legend in
substantially the following form (and a stop-transfer order may be placed
against transfer of such stock certificates):

                                      -4-
<PAGE>   5

        THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
        REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
        APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE
        OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE
        ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE
        SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
        APPLICABLE STATE SECURITIES LAWS OR (B) AN OPINION OF COUNSEL,
        REASONABLY ACCEPTABLE TO THE COMPANY, THAT REGISTRATION IS NOT
        REQUIRED UNDER SAID ACT OR APPLICABLE STATE SECURITIES LAWS OR
        (II) UNLESS SOLD PURSUANT TO RULE 144 UNDER SAID ACT.
        NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN
        CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN SECURED
        BY THE SECURITIES.

The legend set forth above shall be removed and the Company shall issue a
certificate without such legend to the holder of the Securities upon which it is
stamped, if, unless otherwise required by state securities laws, (i) such
Securities are registered for resale under the 1933 Act, (ii) in connection with
a sale, assignment or transfer , such holder provides the Company with an
opinion of counsel, reasonably acceptable to the Company, to the effect that a
sale, assignment or transfer of the Securities may be made without registration
under the 1933 Act, or (iii) such holder provides the Company with reasonable
assurances that the Securities can be sold pursuant to Rule 144 without any
restriction as to the number of securities acquired as of a particular date that
can then be immediately sold.

                h. Authorization; Enforcement; Validity. This Agreement and the
Registration Rights Agreement have been duly and validly authorized, executed
and delivered on behalf of such Buyer and are valid and binding agreements of
such Buyer enforceable against such Buyer in accordance with their terms,
subject as to enforceability to general principles of equity and to applicable
bankruptcy, insolvency, reorganization, moratorium, liquidation and other
similar laws relating to, or affecting generally, the enforcement of applicable
creditors' rights and remedies.

                i. Residency. Such Buyer is a resident of that jurisdiction
specified in its address on the Schedule of Buyers.

        3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

                The Company represents and warrants to each of the Buyers that
as of the date hereof and as of each of the Closing Dates (as such
representations and warranties are modified by the Company's schedules updated
pursuant to Section 4(m), as necessary, on each of the Additional Closing
Dates):

                a. Organization and Qualification. The Company and its
"SUBSIDIARIES" (which for purposes of this Agreement means any entity (A) in
which the Company, directly or

                                      -5-
<PAGE>   6

indirectly, owns 50% or more of the capital stock or holds 50% or more of the
equity or a similar interest of the Company and (B) whose business, properties,
assets, operations, results of operations or financial condition are material to
the Company) are corporations duly organized and validly existing in good
standing under the laws of the jurisdiction in which they are incorporated, and
have the requisite corporate power and authorization to own their properties and
to carry on their business as now being conducted. Each of the Company and its
Subsidiaries is duly qualified as a foreign corporation to do business and is in
good standing in every jurisdiction in which its ownership of property or the
nature of the business conducted by it makes such qualification necessary,
except to the extent that the failure to be so qualified or be in good standing
would not reasonably be expected to have a Material Adverse Effect. As used in
this Agreement, "MATERIAL ADVERSE EFFECT" means any material adverse effect on
(i) the business, properties, assets, operations, results of operations or
financial condition of the Company and its Subsidiaries, if any, taken as a
whole, (ii) the transactions contemplated hereby or by the agreements and
instruments to be entered into in connection herewith, other than solely by a
decline in the market price of the Common Stock, or (iii) the authority or
ability of the Company to perform its obligations under the Transaction
Documents (as defined below). A complete list of entities in which the Company,
directly or indirectly, owns capital stock or holds an equity or similar
interest is set forth on Schedule 3(a).

                b. Authorization; Enforcement; Validity. The Company has the
requisite corporate power and authority to enter into and perform its
obligations under this Agreement, the Registration Rights Agreement, the
Irrevocable Transfer Agent Instructions (as defined in Section 5), the Notes and
each of the other agreements entered into by the parties hereto in connection
with the transactions contemplated by this Agreement (collectively, the
"TRANSACTION DOCUMENTS"), and to issue the Securities in accordance with the
terms hereof and thereof. The execution and delivery of the Transaction
Documents by the Company and the consummation by it of the transactions
contemplated hereby and thereby, including without limitation the issuance of
the Notes and the reservation for issuance and the issuance of the Conversion
Shares issuable upon conversion or exercise thereof, have been duly authorized
by the Company's Board of Directors and no further consent or authorization is
required by the Company, its Board of Directors or its stockholders. The
Transaction Documents have been duly executed and delivered by the Company. The
Transaction Documents constitute the valid and binding obligations of the
Company enforceable against the Company in accordance with their terms, except
as such enforceability may be limited by general principles of equity or
applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or
similar laws relating to, or affecting generally, the enforcement of creditors'
rights and remedies.

                c. Capitalization. As of the date hereof, the authorized capital
stock of the Company consists of (i) 150,000,000 shares of Common Stock, of
which as of May 30, 2000, 66,054,041 shares were issued and outstanding,

exchangeable for, or convertible into, shares of Common Stock and (ii) 1,000,000
shares of Preferred Stock, of which as of the date hereof, no shares are issued
and outstanding. During the period between

                                      -6-
<PAGE>   7

May 30, 2000 and the date hereof, no additional issuances of Common Stock have
been made which in the aggregate exceed 50,000 shares of Common Stock. All of
such outstanding shares have been validly issued and are fully paid and
nonassessable. Except as disclosed in Schedule 3(c), (A) no shares of the
Company's capital stock are subject to preemptive rights or any other similar
rights or any liens or encumbrances suffered or permitted by the Company; (B)
there are no outstanding debt securities issued by the Company; (C) there are no
outstanding options, warrants, scrip, rights to subscribe to, calls or
commitments of any character whatsoever relating to, or securities or rights
convertible into, any shares of capital stock of the Company or any of its
Subsidiaries, or contracts, commitments, understandings or arrangements by which
the Company or any of its Subsidiaries is or may become bound to issue
additional shares of capital stock of the Company or any of its Subsidiaries or
options, warrants, scrip, rights to subscribe to, calls or commitments of any
character whatsoever relating to, or securities or rights convertible into, any
shares of capital stock of the Company or any of its Subsidiaries; (D) there are
no agreements or arrangements under which the Company or any of its Subsidiaries

of its Subsidiaries; (F) there are no securities or instruments containing
anti-dilution or similar provisions that will be triggered by the issuance of
the Securities as described in this Agreement; and (G) the Company does not have
any stock appreciation rights or "phantom stock" plans or agreements or any

correct copies of the Company's Certificate of Incorporation, as amended and as
in effect on the date hereof (the "CERTIFICATE OF INCORPORATION"), and the
Company's Bylaws, as amended and as in effect on the date hereof (the "BYLAWS"),
and the terms of all securities convertible into or exercisable for Common Stock
and the material rights of the holders thereof in respect thereto.

                d. Issuance of Securities. The Notes are duly authorized and at
least 16,000,000 shares of Common Stock (subject to adjustment pursuant to the
Company's covenant set forth in Section 4(f) below) have been duly authorized
and reserved for issuance upon conversion of the Notes. Upon conversion in
accordance with the Notes the Conversion Shares will be validly issued, fully
paid and nonassessable and free from all taxes, liens and charges with respect
to the issue thereof, with the holders being entitled to all rights accorded to
a holder of Common Stock. Assuming the accuracy of the Buyer's representations
and warranties as to factual matters contained in Sections 2(a), 2(b) and 2(d),
the issuance by the Company of the Securities is exempt from registration under
the 1933 Act.

                e. No Conflicts. Except as disclosed in Schedule 3(e), the
execution, delivery and performance of the Transaction Documents by the Company,
the performance by the Company of its obligations under the Notes and the
consummation by the Company of the transactions contemplated hereby and thereby
(including, without limitation, the reservation for issuance and issuance of the
Conversion Shares) will not (i) result in a violation of the Certificate of
Incorporation or the Bylaws; (ii) conflict with, or constitute a default (or an
event which with

                                      -7-
<PAGE>   8

notice or lapse of time or both would become a default) under, or give to others
any rights of termination, amendment, acceleration or cancellation of, any
material agreement, indenture or instrument to which the Company or any of its
Subsidiaries is a party; (iii) result in a violation of any law, rule,
regulation, order, judgment or decree (including federal and state securities
laws and regulations and the rules and regulations of the Principal Market (as
defined below)) applicable to the Company or any of its Subsidiaries or by which
any property or asset of the Company or any of its Subsidiaries is bound or
affected. Except as disclosed in Schedule 3(e), neither the Company nor its
Subsidiaries is in violation of any term of its Certificate of Incorporation or
the Bylaws or their organizational charter or bylaws, respectively. Except as
disclosed in Schedule 3(e), neither the Company or any of its Subsidiaries is in
violation or any term of or in default under any contract, agreement, mortgage,
indebtedness, indenture, instrument, judgment, decree or order or any statute,
rule or regulation applicable to the Company or its Subsidiaries, except where
such violations and defaults would not reasonably be expected to result, either
individually or in the aggregate, in a Material Adverse Effect. The business of
the Company and its Subsidiaries is not being conducted in violation of any law,
ordinance or regulation of any governmental entity, except where such violations
would not reasonably be expected to result, either individually or in the
aggregate, in a Material Adverse Effect. Except as specifically contemplated by
this Agreement and as required under the 1933 Act and state securities laws, the
Company is not required to obtain any consent, authorization or order of, or
make any filing or registration with, any court or governmental agency or any
regulatory or self-regulatory agency in order for it to execute, deliver or
perform any of its obligations under or contemplated by the Transaction
Documents, in each case in accordance with the terms hereof or thereof. Except
as disclosed in Schedule 3(e), all consents, authorizations, orders, filings and
registrations which the Company is required to obtain pursuant to the preceding

Company is not in violation of the listing requirements of the Principal Market,
including, without limitation, the requirements set forth in Rule
4310(c)(25)(G)(iv)(d) of the Principal Market and has no actual knowledge of any
facts which would reasonably lead to delisting or suspension of the Common Stock
by the Principal Market in the foreseeable future.

                f. SEC Documents; Financial Statements. Since January 3, 1999,
the Company has filed all reports, schedules, forms, statements and other
documents required to be filed by it with the SEC pursuant to the reporting
requirements of the Securities Exchange Act of 1934, as amended (the "1934 ACT")
(all of the foregoing filed prior to the date hereof and all exhibits included

incorporated by reference therein being hereinafter referred to as the "SEC
DOCUMENTS"). As of their respective dates, the SEC Documents complied in all
material respects with the requirements of the 1934 Act and the rules and
regulations of the SEC promulgated thereunder applicable to the SEC Documents.
None of the SEC Documents, at the time they were filed with the SEC or as
revised in a subsequent amendment filed prior to the date hereof, contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading. As of
their respective dates, the

                                      -8-
<PAGE>   9

financial statements of the Company included in the SEC Documents complied as to
form in all material respects with applicable accounting requirements and the
published rules and regulations of the SEC with respect thereto. Such financial
statements have been prepared in accordance with generally accepted accounting
principles, consistently applied, during the periods involved (except (i) as may
be otherwise indicated in such financial statements or the notes thereto, or
(ii) in the case of unaudited interim statements, to the extent they may exclude
footnotes or may be condensed or summary statements) and fairly present in all
material respects the financial position of the Company as of the dates thereof
and the results of its operations and cash flows for the periods then ended
(subject, in the case of unaudited statements, to normal year-end audit
adjustments). No other information provided by or on behalf of the Company to
the Buyers which is not included in the SEC Documents, including, without
limitation, information referred to in Section 2(d), contains any untrue
statement of a material fact or omits to state any material fact necessary in
order to make the statements therein, in the light of the circumstance under
which they are or were made, not misleading. Neither the Company nor any of its
Subsidiaries or any of their officers, directors, employees or agents have
directly provided the Buyers with any material, nonpublic information, except
for the information that the Company is required to disclose pursuant to Section
4(h).

                g. Absence of Certain Changes. Except as disclosed in Schedule
3(g), since January 2, 2000 there has been no material adverse change and no
material adverse development in the business, properties, assets, operations,
results of operations or financial conditions of the Company or its Subsidiaries
taken as a whole. The Company has not taken any steps, and does not currently
expect to take any steps, to seek protection pursuant to any bankruptcy law nor
does the Company or any of its Subsidiaries have any knowledge that its
creditors intend to initiate involuntary bankruptcy proceedings or any actual
knowledge of any fact which would reasonably lead a creditor to do so. Except as
disclosed in Schedule 3(g), since April 2, 2000 the Company has not declared or
paid any dividends, sold any assets in the aggregate in excess of $5,000,000
outside of the ordinary course of business or had capital expenditures in the
aggregate in excess of $5,000,000.

                h. Absence of Litigation. Except for such as would not have
either individually or in the aggregate a Material Adverse Effect, there is no
action, suit, proceeding, inquiry or investigation before or by any court,
public board, government agency, self-regulatory organization or body pending
or, to the knowledge of the Company threatened against or affecting the Company,
the Common Stock or, to the knowledge of the Company, any of the Subsidiaries or
any of the Company's or the Subsidiaries' officers or directors in their
capacities as such. To the knowledge of the Company none of the directors or
officers of the Company in their capacities as such have been involved in
securities related litigation during the past five years.

                i. Acknowledgment Regarding Buyer's Purchase of Notes. The
Company acknowledges and agrees that each of the Buyers is acting solely in the
capacity of an arm's length purchaser with respect to the Transaction Documents
and the transactions contemplated hereby and thereby. The Company further
acknowledges that each Buyer is not acting as a financial advisor or fiduciary
of the Company (or in any similar capacity) with respect to the Transaction

                                      -9-
<PAGE>   10

Documents and the Certificate of Designation and the transactions contemplated
hereby and thereby and any advice given by any of the Buyers or any of their
respective representatives or agents in connection with the Transaction
Documents and the transactions contemplated hereby and thereby is merely
incidental to such Buyer's purchase of the Securities. The Company further
represents to each Buyer that the Company's decision to enter into the
Transaction Documents has been based solely on the independent evaluation by the
Company and its representatives.

                j. Intentionally left blank.

                k. No General Solicitation. Neither the Company, nor any of its
affiliates, nor any person acting on its or their behalf, has engaged in any
form of general solicitation or general advertising (within the meaning of
Regulation D under the 1933 Act) in connection with the offer or sale of the
Securities.

                l. No Integrated Offering. Neither the Company, nor any of its
officers, directors or Subsidiaries, nor any person acting on its or their
behalf has, directly or indirectly, made any offers or sales of any security or
solicited any offers to buy any security, under circumstances that would require
registration of any of the Securities under the 1933 Act or cause this offering
of the Securities to be integrated with prior offerings by the Company for
purposes of the 1933 Act or any applicable stockholder approval provisions,
including, without limitation, under the rules and regulations of any exchange
or automated quotation system on which any of the securities of the Company are
listed or designated, nor will the Company or any of its Subsidiaries take any
action or steps that would require registration of any of the Securities under
the 1933 Act or cause the offering of the Securities to be integrated with other
offerings.

                m. Intellectual Property Rights. To the Company's knowledge, the
Company and its Subsidiaries own or possess or can obtain on commercially
reasonable terms adequate rights or licenses to use all trademarks, trade names,
service marks, service mark registrations, service names, patents, patent
rights, copyrights, inventions, licenses, approvals, governmental
authorizations, trade secrets and other intellectual property rights necessary
to conduct their respective businesses as now conducted. Except to the extent
that such infringement would not have, either individually or in the aggregate,
a Material Adverse Effect, the Company does not have any knowledge of any
infringement by the Company or its Subsidiaries of trademarks, trade names,
service marks, service mark registrations, service names, patents, patent
rights, copyrights, inventions, licenses, trade secrets or other intellectual
property rights of others, or of any development of similar or identical trade
secrets or technical information by others and there is no claim, action or
proceeding being made or brought against, or to the Company's knowledge, being
threatened against, the Company or its Subsidiaries regarding its trademarks,
trade names, service marks, service mark registrations, service names, patents,
patent rights, copyrights, inventions, licenses, trade secrets, or infringement
of other intellectual property rights, except to the extent that such claim,
action or proceeding, either individually or in the aggregate, would not have a
Material Adverse Effect; and the Company is unaware of any facts or
circumstances which might give rise to any of the foregoing. The Company has
taken reasonable security measures to protect the secrecy, confidentiality and
value of all of their intellectual properties.

                                      -10-

                n. Title. The Company and its U.S. Subsidiaries have good and
marketable title in fee simple to all real property and good and marketable
title to all personal property owned by them which is material to the business
of the Company and its Subsidiaries, in each case free and clear of all liens,
encumbrances and defects except such as do not materially affect the value of
such property and do not interfere with the use made and proposed to be made of
such property by the Company and any of its Subsidiaries. To the best of the
Company's knowledge, any real property and facilities held under lease by the
Company and any of its Subsidiaries are held by them under valid, subsisting and
enforceable leases with such exceptions as are not material and do not interfere
with the use made and proposed to be made of such property and facilities by the
Company and its Subsidiaries.

                o. Regulatory Permits. To the Company's knowledge and except the
absence of which would not reasonably be expected to result, either individually
or in the aggregate, in a Materially Adverse Effect, the Company and its
Subsidiaries possess all certificates, authorizations and permits issued by the
appropriate federal, state or foreign regulatory authorities necessary to
conduct their respective businesses, and neither the Company nor any such
Subsidiary has received any notice of proceedings relating to the revocation or
modification of any such certificate, authorization or permit.

                p. Internal Accounting Controls. The Company and to the
Company's knowledge each of its Subsidiaries maintain a system of internal
accounting controls sufficient to provide reasonable assurance that (i)
transactions are executed in accordance with management's general or specific
authorizations, (ii) transactions are recorded as necessary to permit
preparation of financial statements in conformity with generally accepted
accounting principles and to maintain asset accountability, (iii) access to
assets is permitted only in accordance with management's general or specific
authorization and (iv) the recorded accountability for assets is compared with
the existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

                q. Tax Status. The Company and each of its Subsidiaries (i) has
made or filed all federal and state income and all other tax returns, reports
and declarations required by any jurisdiction to which it is subject (unless and
only to the extent that the Company and each of its Subsidiaries has set aside
on its books provisions reasonably adequate for the payment of all unpaid and
unreported taxes), (ii) has paid all taxes and other governmental assessments
and charges that are material in amount, shown or determined to be due on such
returns, reports and declarations, except those being contested in good faith
and for which the Company has made appropriate reserves for on its books, and
(iii) has set aside on its books provisions reasonably adequate for the payment
of all taxes for periods subsequent to the periods to which such returns,
reports or declarations (referred to in clause (i) above) apply. There are no
unpaid taxes in any material amount claimed to be due by the taxing authority of
any jurisdiction, and the officers of the Company know of no basis for any such
claim.

                                      -11-
<PAGE>   12

                r. Transactions With Affiliates. Except as set forth on Schedule
3(r) and in the SEC Documents filed at least ten days prior to the date hereof,
and other than the grant of stock options disclosed on Schedule 3(c), none of
the officers, directors, or employees of the Company is presently a party to any
material transaction with the Company or any of its Subsidiaries (other than for
services as employees, officers and directors), including any contract,
agreement or other arrangement providing for the furnishing of services to or
by, providing for rental of real or personal property to or from, or otherwise
requiring payments to or from any such officer, director or employee or, to the
knowledge of the Company, any corporation, partnership, trust or other entity in
which any such officer, director, or employee has a substantial interest or is
an officer, director, trustee or partner.

                s. Application of Takeover Protections. The Company does not
have any control share acquisition, business combination, poison pill (including
any distribution under a rights agreement) or other similar anti-takeover
provision under the Certificate of Incorporation.

                t. Rights Agreement. The Company has not adopted a shareholder
rights plan or similar arrangement relating to accumulations of beneficial
ownership of Common Stock or a change in control of the Company.

                u. Foreign Corrupt Practices. To the best of the Company's
knowledge, neither the Company, nor any of its Subsidiaries, nor any director,
officer, agent, employee or other person acting on behalf of the Company or any
of its Subsidiaries has, in the course of its actions for, or on behalf of, the
Company, used any corporate funds for any unlawful contribution, gift,
entertainment or other unlawful expenses relating to political activity; made
any direct or indirect unlawful payment to any foreign or domestic government
official or employee from corporate funds; violated or is in violation of any
provision of the U.S. Foreign Corrupt Practices Act of 1977, as amended; or made
any unlawful bribe, rebate, payoff, influence payment, kickback or other
unlawful payment to any foreign or domestic government official or employee.

        4. COVENANTS.

                a. Best Efforts. Each party shall use its best efforts to timely
satisfy each of the conditions to be satisfied by it as provided in Sections 6
and 7 of this Agreement.

                b. Form D and Blue Sky. The Company agrees to file a Form D with
respect to the Securities as required under Regulation D and to provide a copy
thereof to each Buyer promptly after such filing. The Company shall, on or
before each of the Closing Dates, take such action as the Company shall
reasonably determine is necessary in order to obtain an exemption for or to
qualify the Securities for sale to the Buyers at each of the Closings pursuant
to this Agreement under applicable securities or "Blue Sky" laws of the states
of the United States, and shall provide evidence of any such action so taken to
the Buyers on or prior to the Closing Dates. The Company shall make all filings
and reports relating to the offer and sale of the Securities required under
applicable securities or "Blue Sky" laws of the states of the United States
following each of the Closing Dates.

                                      -12-
<PAGE>   13

                c. Reporting Status. Until the later of (i) the date which is
one year after the date as of which the Investors (as that term is defined in
the Registration Rights Agreement) may sell all of the Conversion Shares without
restriction pursuant to Rule 144(k) promulgated under the 1933 Act (or successor
thereto) and (ii) the date on which the Investors have sold all Conversion
Shares which they may acquire pursuant to this Agreement or the Notes, which
date shall not be later than five (5) years from the last Closing Date to occur
(the "REPORTING PERIOD"), the Company shall file all reports required to be
filed with the SEC pursuant to the 1934 Act, and the Company shall not terminate
its status as an issuer required to file reports under the 1934 Act even if the
1934 Act or the rules and regulations thereunder would otherwise permit such
termination.

                d. Financial Information. The Company agrees to send the
following to each Investor during the Reporting Period: (i) within two (2) days
after the filing thereof with the SEC (unless available on the EDGAR System), a
copy of its Annual Reports on Form 10-K, its Quarterly Reports on Form 10-Q, any
Current Reports on Form 8-K and any registration statements (other than on Form
S-8) or amendments filed pursuant to the 1933 Act, provided that if any such
report is not filed with the SEC through EDGAR then the Company shall deliver a
copy of such report to each Investor by facsimile on the same day it is filed
with the SEC and (ii) to use its best efforts to provide copies of any notices
and other information made available or given to the stockholders of the Company
generally, contemporaneously with the making available or giving thereof to the
stockholders. The Company will add the Investors to its email distribution list
which it maintains to disseminate its press releases.

                e. Reservation of Shares. The Company shall take all action
necessary to at all times have authorized, and reserved for the purpose of
issuance of Conversion Shares, at least the greater of (i) the number of shares
of Common Stock to provide for the issuance of the shares of Common Stock upon
conversion of all outstanding Notes (without regard to any limitations on
conversions) and (ii) 16,000,000 shares of Common Stock.

                f. Listing. The Company shall promptly secure the listing of all
of the Registrable Securities (as defined in the Registration Rights Agreement)
upon each national securities exchange and automated quotation system, if any,
upon which shares of Common Stock are then listed (subject to official notice of
issuance) and shall maintain, so long as any other shares of Common Stock shall
be so listed, such listing of all Registrable Securities from time to time
issuable under the terms of the Transaction Documents. The Company shall
maintain the Common Stock's authorization for quotation on the Nasdaq National
Market ("NASDAQ") or listed on The New York Stock Exchange ("NYSE") or The
American Stock Exchange ("AMEX"). Neither the Company nor any of its
Subsidiaries shall take any action which would be reasonably expected to result
in the delisting or suspension of the Common Stock from any such market. The
Company shall pay all fees and expenses in connection with satisfying its
obligations under this Section 4(f).

                                      -13-
<PAGE>   14

                g. Expenses. Subject to Section 9(l) below, at the Initial
Closing, the Company shall reimburse the Buyers for the Buyers' expenses
(including reasonable attorneys' fees and expenses) in due diligence and
negotiating and preparing the Transaction Documents and consummating the
transactions contemplated thereby of up to $50,000. Such amount will be paid by
the Company by wire transfer of immediately available funds within 5 days of the
Company's receipt of invoices for expenses to be reimbursed pursuant to this
Section 4(g).

                h. Filing of Form 8-K. On the first (1st) Business Day following
the date on which the transaction which restructures the Bank Debt closes, the
Company shall publicly disclose the material terms of the Bank Debt by filing
with the SEC a Form 8-K (the "BANK DEBT FORM 8-K") describing the terms of the
Bank Debt and including as exhibits to the Bank Debt Form 8-K such agreements
which set forth the Bank Debt. On the date the Company files the Bank Debt Form
8-K, the Company shall file a Form 8-K with the SEC describing the terms of the
transactions contemplated by the Transaction Documents and including as exhibits
to such Form 8-K this Agreement, the Note and the Registration Rights Agreement
in the form required by the 1934 Act. On or before the first (1st) Business Day
following each Additional Closing Date and Additional Note Notice Date the
Company shall file a Form 8-K with the SEC describing the transaction
consummated or proposed on such date.

                i. Corporate Existence. So long as a Buyer beneficially owns any
Notes the Company shall maintain its corporate existence and shall not sell all
or substantially all of the Company's assets, except in the event of a merger or
consolidation or sale of all or substantially all of the Company's assets, where
the surviving or successor entity in such transaction (i) assumes the Company's
obligations hereunder and under the agreements and instruments entered into in
connection herewith and (ii) is a publicly traded corporation whose common stock
is quoted on or listed for trading on Nasdaq, AMEX or NYSE.

                j. Right of First Offer. Subject to the exceptions described
below, the Company agrees that during the period beginning on the date hereof
and ending on and including the date which is 183 days after the Initial Closing
Date, neither the Company nor its Subsidiaries will negotiate or contract with
any party for any equity financing (including any debt financing with an equity
component) or issue any equity securities of the Company or any Subsidiary or
securities convertible or exchangeable into or for equity securities of the
Company or any Subsidiary (including debt securities with an equity component)
in any form (a "PROPOSED OFFERING") unless it shall have first delivered to each
Buyer or a designee appointed by such Buyer written notice (the "OFFERING
NOTICE") describing the proposed Participation Offering, including the size,
terms and conditions thereof, and providing each Buyer an option to offer terms
to the Company for the Proposed Offering (the limitations referred to in this
sentence are collectively referred to as the "CAPITAL RAISING LIMITATIONS").
Notwithstanding the foregoing, the Company shall retain the right to accept such
Buyer's terms for the Proposed Offering, to attempt to secure better terms from
other investors, or postpone or discontinue such Proposed Offering. A Buyer
shall exercise its option to offer terms to the Company for the Proposed
Offering by delivering written notice of such terms to the Company within 10
Business Days after receipt of a Proposed Offering Notice. Within five (5)
Business Days of the Company's receipt of proposed terms from

                                      -14-
<PAGE>   15

a Buyer pursuant to this Section 4(j), the Company shall notify such Buyer in
writing of the Company's election to accept such terms, to attempt to secure
better terms from other investors, or postpone or discontinue such Proposed
Offering. In the event the Company has not sold such securities of the Proposed
Offering within such 135 days of the Company's delivery of the Offering Notice,
the Company shall not thereafter issue or sell such securities without first
notifying each Buyer of the proposed offering in the manner provided in this
Section 4(j). The Capital Raising Limitations shall not apply to (i) a loan from
a commercial bank, insurance company or other institutional investor which does
not have any equity feature, (ii) any transaction involving the Company's
issuances of securities (A) as consideration in a merger or consolidation, (B)
in connection with any strategic partnership or joint venture (the primary
purpose of which is not to raise equity capital), or (C) as consideration for
the acquisition of a business, product, license or other assets by the Company,
(iii) the issuance of Common Stock or debt in a firm commitment, underwritten
public offering, (iv) the issuance of securities upon exercise or conversion of
the Company's options, warrants or other convertible securities outstanding as
of the date hereof, (v) the grant of additional options or warrants, or the
issuance of additional securities, under any Company stock option plan,
restricted stock plan or stock purchase plan for the benefit of the Company's
employees, directors or consultants, (vi) the issuance of securities pursuant to
an offering by the Company in reliance upon Rule 144A under the 1933 Act with
proceeds to the Company of at least $50,000,000 and (vii) the issuance of
convertible debt in exchange for Bank Debt not held by the Holders of the Notes.
The Buyers shall not be required to offer terms for a particular Proposed
Offering in order to have the right to receive notice with respect to later
Proposed Offerings.

                k. Organizational Chart. The Company shall provide the Buyers
with an organizational chart describing the relationship between the Company and
each of the entities listed on Schedule 3(a) on or prior to the Initial Closing
Date, which organizational chart shall not disclose any material nonpublic
information.

                l. Limitation on the Sales of Common Stock. During any period
beginning on and including a date which is eight (8) Business Days prior to an
Additional Note Notice Date and ending on and excluding such Additional Note
Notice Date, each Buyer agrees that neither such Buyer nor its affiliates will
sell any shares of the Company's Common Stock.

                m. Schedules. The Company shall update the disclosure schedules
made pursuant to Section 3 hereof on each Additional Closing Date so as to make
the Company's representations and warranties on such date true and correct as of
such date.

                n. Transfer Agent Instructions. The Irrevocable Transfer Agent
Instructions, in the form of Exhibit D attached hereto, shall be delivered to
and acknowledged in writing by the Company's transfer agent on or prior to June
6, 2000.

                o. Restructured Loan Agreement. So long as the any principal
amount of the Notes is outstanding, the Company shall comply in all respects
with the Senior Credit Facility (as

                                      -15-
<PAGE>   16
defined in Section 23 of the Notes) and shall immediately pay all amounts due
and owing under the Senior Credit Facility.

        5. TRANSFER AGENT INSTRUCTIONS.

                The Company shall issue irrevocable instructions to its transfer
agent, and any subsequent transfer agent, to issue certificates, registered in
the name of each Buyer or its respective nominee(s), for the Conversion Shares
in such amounts as specified from time to time by each Buyer to the Company upon
conversion of the Notes (the "IRREVOCABLE TRANSFER AGENT INSTRUCTIONS"). Prior
to registration of the Conversion Shares under the 1933 Act, all such
certificates shall bear the restrictive legend specified in Section 2(g). The
Company warrants that no instruction other than the Irrevocable Transfer Agent
Instructions referred to in this Section 5 and stop transfer instructions to
give effect to Section 2(f) (in the case of the Conversion Shares, prior to
registration of the Conversion Shares under the 1933 Act) will be given by the
Company to its transfer agent and that the Securities shall otherwise be freely
transferable on the books and records of the Company as and to the extent
provided in this Agreement and the Registration Rights Agreement. If a Buyer
provides the Company with an opinion of counsel, in a generally acceptable form,
to the effect that a sale, assignment or transfer of the Securities may be made
without registration under the 1933 Act or the Buyer provides the Company with
reasonable assurances that the Securities can be sold pursuant to Rule 144
without any restriction as to the number of securities acquired as of a
particular date that can then be immediately sold, the Company shall permit the
transfer, and, in the case of the Conversion Shares, promptly instruct its
transfer agent to issue one or more certificates in such name and in such
denominations as specified by such Buyer and without any restrictive legend. The
Company acknowledges that a breach by it of its obligations hereunder will cause
irreparable harm to each Buyer by vitiating the intent and purpose of the
transaction contemplated hereby. Accordingly, the Company acknowledges that the
remedy at law for a breach of its obligations under this Section 5 will be
inadequate and agrees, in the event of a breach or threatened breach by the
Company of the provisions of this Section 5, that the each Buyer shall be
entitled, in addition to all other available remedies, to an order and/or
injunction restraining any breach and requiring immediate issuance and transfer,
without the necessity of showing economic loss and without any bond or other
security being required.

        6. CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL.

                a. Initial Closing Date. The obligation of the Company to issue

following conditions, provided that these conditions are for the Company's sole
benefit and may be waived by the Company at any time in its sole discretion by
providing each Buyer with prior written notice thereof:

        Buyer to the Company.

                (iii) The representations and warranties of such Buyer shall be
        true and correct as of the date when made and as of the Initial Closing

        performed, satisfied and complied with the covenants, agreements and
        conditions required by the Transaction Documents to be performed,
        satisfied or complied with by such Buyer at or prior to the Initial
        Closing Date.

                (iv) Each Buyer shall have purchased the principal amount of
        Initial Notes set forth on the Schedule of Buyers.

                b. Additional Closing Date. The obligation of the Company
hereunder to issue and sell the Additional Notes to each Buyer at each
Additional Closing is subject to the satisfaction, at or before such Additional
Closing Date, of each of the following conditions, provided that these

        the Company in an amount equal to the Purchase Price in exchange for the

        such Buyer shall have performed, satisfied and complied with the
        covenants, agreements and conditions required by the Transaction
        Documents to be performed, satisfied or complied with by such Buyer at

                (iii) The principal amount of Additional Notes being purchased
        at such Additional Closing shall equal or exceed $3,500,000.

                (iv) Each Buyer purchasing Additional Notes in the applicable
        Additional Closing shall have satisfied conditions (i) through (iii) of
        this Section 6(b).

        8. INTENTIONALLY LEFT BLANK.

        9. GOVERNING LAW; MISCELLANEOUS.

                a. Governing Law; Jurisdiction; Jury Trial. All questions
concerning the construction, validity, enforcement and interpretation of this
Agreement shall be governed by the internal laws of the State of Illinois,
without giving effect to any choice of law or conflict of law provision or rule
(whether of the State of Illinois or any other jurisdiction) that would cause
the application of the laws of any jurisdiction other than the State of
Illinois. Each party hereby irrevocably submits to the non-exclusive
jurisdiction of the state and federal courts sitting in the City of Chicago,
Cook County, for the adjudication of any dispute hereunder or in connection
herewith or with any transaction contemplated hereby or discussed herein, and
hereby irrevocably waives, and agrees not to assert in any suit, action or
proceeding, any claim that it is not personally subject to the jurisdiction of
any such court, that such suit, action or proceeding is brought in an
inconvenient forum or that the venue of such suit, action or proceeding is
improper. Each party hereby irrevocably waives personal service of process and
consents to process being served in any such suit, action or proceeding by
mailing a copy thereof to such party at the address for such notices to it under
this Agreement and agrees that such service shall constitute good and sufficient
service of process and notice thereof. Nothing contained herein shall be deemed
to limit in any way any right to serve process in any manner permitted by law.

                b. Counterparts. This Agreement may be executed in two or more
identical counterparts, all of which shall be considered one and the same
agreement and shall become effective when counterparts have been signed by each
party and delivered to the other party; provided that a facsimile signature
shall be considered due execution and shall be binding upon the signatory
thereto with the same force and effect as if the signature were an original, not
a facsimile signature.

                c. Headings. The headings of this Agreement are for convenience
of reference and shall not form part of, or affect the interpretation of, this
Agreement.

                d. Severability. If any provision of this Agreement shall be
invalid or unenforceable in any jurisdiction, such invalidity or
unenforceability shall not affect the validity or enforceability of the
remainder of this Agreement in that jurisdiction or the validity or
enforceability of any provision of this Agreement in any other jurisdiction.

                e. Entire Agreement; Amendments. This Agreement supersedes all
other prior oral or written agreements between each Buyer, the Company, their
affiliates and persons acting on their behalf with respect to the matters
discussed herein, and this Agreement and the instruments referenced herein
contain the entire understanding of the parties with respect to the matters
covered herein and therein and, except as specifically set forth herein or
therein, neither the Company nor any Buyer makes any representation, warranty,
covenant or undertaking with respect to such matters. No provision of this
Agreement may be amended or waived other than by an instrument in writing signed
by the Company and the holders of at least two-thirds (b) of the principle
amount of the Initial Notes purchased on the Initial Closing Date or, if prior
to the Initial Closing Date, the Buyers listed on the Schedule of Buyers as
being obligated to purchase at least two-thirds (b) of the principal amount of
the Initial Notes issued on the Initial Closing Date. No such amendment shall be
effective to the extent that it applies to less than all of the holders of the
Notes then outstanding. No consideration shall be offered or paid to any person
to amend or consent to a waiver or modification of any provision of any of the
Transaction Documents unless the same consideration also is offered to all of
the parties to the Transaction Documents or holders of Notes, as the case may
be.

                f. Notices. Any notices, consents, waivers or other
communications required or permitted to be given under the terms of this
Agreement must be in writing and will be deemed to have been delivered: (i) upon
receipt, when delivered personally; (ii) upon receipt, when sent by facsimile
(provided confirmation of transmission is mechanically or electronically
generated and kept on file by the sending party); or (iii) one Business Day

                           Attention:   Duane Knutsen

If to a Buyer, to it at the address and facsimile number set forth on the
Schedule of Buyers, with copies to such Buyer's representatives as set forth on
the Schedule of Buyers, or at such other address and/or facsimile number and/or

                g. Successors and Assigns. This Agreement shall be binding upon
and inure to the benefit of the parties and their respective successors and
assigns, including any purchasers of the Notes. The Company shall not assign
this Agreement or any rights or obligations hereunder without the prior written
consent of the holders of a majority of the Notes then outstanding, including by
merger or consolidation, except pursuant to a Change of Control (as defined in
Section 4(b) of the Notes) with respect to which the Company is in compliance
with Section 4(i) of this Agreement and Section 4 of the Notes. A Buyer may
assign some or all of its rights hereunder without the consent of the Company,
provided, however, that any such assignment shall not release such Buyer from
its obligations hereunder unless such obligations are assumed by such assignee
and the Company has consented to such assignment and assumption, which consent
shall not be unreasonably withheld. Notwithstanding anything to the contrary
contained in the Transaction Documents, the Buyers shall be entitled to pledge
the Securities in connection with a bona fide margin account or other loan
secured by the Securities.

                h. No Third Party Beneficiaries. This Agreement is intended for
the benefit of the parties hereto and their respective permitted successors and
assigns, and is not for the benefit of, nor may any provision hereof be enforced
by, any other person.

                i. Survival. Unless this Agreement is terminated under Section
9(l), the representations and warranties of the Company and the Buyers contained
in Sections 2 and 3, the agreements and covenants set forth in Sections 4, 5 and
9, and the indemnification provisions set forth in Section 8, shall survive the
Closings. Each Buyer shall be responsible only for its own representations,
warranties, agreements and covenants hereunder. Notwithstanding the above,

                                      -23-
<PAGE>   24

nothing in this Section 9(i) shall serve to change the representations and
warranties contained in Sections 2 and 3 and as given on the date hereof and
each of the Closing Dates into covenants.

                j. Publicity. The Company and each Buyer shall have the right to
approve before issuance any press releases or any other public statements with
respect to the transactions contemplated hereby; provided, however, that the
Company shall be entitled, without the prior approval of any Buyer, to make any
press release or other public disclosure with respect to such transactions as is
required by applicable law and regulations (although each Buyer shall be
consulted by the Company in connection with any such press release or other
public disclosure prior to its release and shall be provided with a copy
thereof).

                k. Further Assurances. Each party shall do and perform, or cause
to be done and performed, all such further acts and things, and shall execute
and deliver all such other agreements, certificates, instruments and documents,
as the other party may reasonably request in order to carry out the intent and
accomplish the purposes of this Agreement and the consummation of the
transactions contemplated hereby.

                l. Termination. In the event that the Initial Closing shall not
have occurred with respect to a Buyer on or before fifteen (15) days from the
date hereof due to the Company's or such Buyer's failure to satisfy the
conditions set forth in Sections 6(a) and 7(a) above (and the nonbreaching
party's failure to waive such unsatisfied condition(s)), the nonbreaching party
shall have the option to terminate this Agreement with respect to such breaching
party at the close of business on such date without liability of any party to
any other party; provided, however, that if this Agreement is terminated
pursuant to this Section 9(l), the Company shall remain obligated to reimburse
any nonbreaching Buyers for the expenses described in Section 4(g) above. In the
event that the Initial Closing shall not have occurred with respect to a Buyer
on or before the date which is fifteen (15) days after the date hereof due to
the failure to satisfy the condition set forth in Section 7(a)(xii) (and such
Buyer's failure to waive such unsatisfied conditions), each of the Company and
such Buyer shall have the option to terminate this Agreement with respect to
such Buyer and the Company at any time after such date without liability of any
party to any other party.

                m. Placement Agent. The Company acknowledges that it has not
engaged a placement agent in connection with the sale of the Notes. Each Buyer
acknowledges that they have not engaged a placement agent in connection with the
purchase of the Notes.

                n. No Strict Construction. The language used in this Agreement
will be deemed to be the language chosen by the parties to express their mutual
intent, and no rules of strict construction will be applied against any party.

                o. Remedies. Each Buyer and each holder of the Securities shall
have all rights and remedies set forth in the Transaction Documents and all
rights and remedies which such holders have been granted and all of the rights
which such holders have under any law. Any person having any rights under any
provision of this Agreement shall be entitled to enforce such

                                      -24-
<PAGE>   25

rights specifically (without posting a bond or other security), to recover
damages by reason of any breach of any provision of this Agreement and to
exercise all other rights granted by law.

                p. Payment Set Aside. To the extent that the Company makes a
payment or payments to the Buyers hereunder or pursuant to the Registration
Rights Agreement or the Notes or the Buyers enforce or exercise their rights
hereunder or thereunder, and such payment or payments or the proceeds of such
enforcement or exercise or any part thereof are subsequently invalidated,
declared to be fraudulent or preferential, set aside, recovered from, disgorged
by or are required to be refunded, repaid or otherwise restored to the Company,
a trustee, receiver or any other Person under any law (including, without
limitation, any bankruptcy law, state or federal law, common law or equitable
cause of action), then to the extent of any such restoration the obligation or
part thereof originally intended to be satisfied shall be revived and continued
in full force and effect as if such payment had not been made or such
enforcement or setoff had not occurred.
