         (c)      the principal amount of such Advance, plus the amount of any
                  outstanding indebtedness to be then combined therewith having
                  the same Applicable Interest Rate and Interest Period, if any,
                  shall be, in the case of Prime-based Advances at least
                  $100,000 and, in the case of a Eurodollar-based Advance, at
                  least $1,000,000 or any larger amount in $100,000 increments;

         (d)      on the proposed date of such Advance, after giving effect to
                  all Advances requested on that day, the principal amount of
                  such Advance, plus the sum of the amount of all other
                  outstanding Advances under this Section 2, shall not exceed
                  the Commitment;

         (e)      a Request for Advance, once delivered to Bank, shall not be
                  revocable by Company.

         (f)      each Request for Advance shall constitute a certification by
                  Company, as of the date hereof:

                  (i)      both before and after such Advance, the obligations
                           of the Loan Parties set forth in this Agreement and
                           the other Loan Documents to which such Persons are
                           parties are valid, binding and enforceable
                           obligations of such Persons;

                  (ii)     all conditions to Advances have been satisfied and
                           shall remain satisfied to the date of such Advance
                           (both before and after giving effect to such
                           Advance);

                  (iii)    there is no Default or Event of Default in existence,
                           and none will exist upon the making of such Advance
                           (both before and after giving effect to such
                           Advance);

                  (iv)     the representations and warranties contained in this
                           Agreement and the other Loan Documents are true and
                           correct in all material respects and shall be true
                           and correct in all material respects as of the making
                           of such Advance (both before and after giving effect
                           to such Advance), other than any representation or
                           warranty that expressly speaks only as of a different
                           date; and

                  (v)      the execution of such Request for Advance will not
                           violate the material terms and conditions of any
                           material contract, agreement or other borrowing of
                           Company.

         2.4 Bank may also, at its option, lend under this Section 2 upon the
telephone request of an authorized officer of Company and, in the event Bank
makes any such advance upon a telephone request, the requesting officer shall
fax to Bank, on the same day as such telephone request, a Request for Advance in
the form attached as Exhibit "C." Company hereby authorizes

                                       9
<PAGE>

Bank to disburse Advances under this Section 2 pursuant to the telephone
instructions of any person purporting to be an authorized officer of Company
and, notwithstanding any provision of this Agreement to the contrary, Company
shall bear all risk of loss resulting from disbursements made upon any telephone
request. Each telephone request for an Advance shall constitute a certification
of the matters set forth in clause (f) of Section 2.3. Company certifies that
Schedule 2.4 lists all Company officers authorized to request Advances by
telephone. Only those officers specified on Schedule 2.4 (as amended or
supplemented in a writing or writings executed by Company and delivered by
Company to Bank in accordance with this Agreement), and no others, are
authorized to make such telephone requests. Any Advance made pursuant to such
telephone request shall only be deposited by Bank into Company's corporate bank
account, Comerica Bank Account Number 1840278004.

         2.5 Company may prepay all or part of the outstanding balance of the
Prime-based Advance(s) under the Note at any time. Upon three (3) Business Days'
prior notice to Bank, Company may prepay all or part of any Eurodollar-based
Advance, provided that the amount of any such partial prepayment shall be at
least $100,000 and the unpaid portion of such Advance which is refunded or
converted under Section 3.3 shall be subject to the limitations of Section
2.3(c) hereof. Any prepayment of a Prime-based Advance or a Eurodollar-based
Advance made in accordance with this Section shall be without premium, penalty
or prejudice to Company's right to reborrow under the terms of this Agreement
subject, in the case of Eurodollar-based Advances, to the provisions of Section
4.1 hereof.

         2.6 Proceeds of Advances under the Note shall be used for general
corporate purposes, including working capital.

         2.7 (a) Provided that no Default or Event of Default has occurred and
is continuing, Company may, upon at least three (3) Business Days' prior written
notice to Bank, permanently reduce the Commitment in whole at any time, or in
part from time to time, without premium or penalty, provided that each partial
reduction of the Commitment shall be in an aggregate amount equal to at least
Ten Million Dollars ($10,000,000) or the aggregate remaining principal amount of
the Commitment, whichever is less.

         (b)      If the Commitment is reduced under Sections 2.7(a) above,
                  Company must prepay in accordance with the terms hereof the
                  amount, if any, by which the aggregate unpaid principal amount
                  of Advances exceeds the amount of the Commitment, taking into
                  account the aforesaid reductions thereof, together with
                  accrued but unpaid interest on the principal amount of such
                  prepaid Advances to the date of prepayment. If the termination
                  or reduction of the Commitment requires the prepayment of a
                  Eurodollar-based Advance on a day other than the last day of
                  the then current Interest Period applicable to such Advance,
                  so long as no Default or Event of Default has occurred and is
                  continuing, Company, rather than immediately prepaying the
                  Advance, may deposit with the Bank cash collateral acceptable
                  to the Bank in an amount equal to the prepayment and required
                  interest payments (to the end of the then current Interest
                  Payment) to be applied to the Advance at the end of that
                  Interest Period. Reductions of the Commitment will not be
                  available for reinstatement by or readvance to the Company and
                  shall be permanent and irrevocable. If the Company permanently
                  reduces the

                                       10
<PAGE>

                  Commitment to zero and has satisfied all of its obligations
                  under this Agreement, this Agreement shall terminate (except
                  for any provisions which, by their terms, explicitly survive
                  the termination of this Agreement and the payment of
                  obligations hereunder).

         3. INTEREST, INTEREST PERIODS, CONVERSIONS, PREPAYMENTS.

         3.1 Interest. The Note and the Advances thereunder shall bear interest
from the date thereof on the unpaid principal balance thereof from time to time
outstanding, at a rate per annum equal to the Prime-based Rate or the
Eurodollar-based Rate, as the Company may elect subject to the provisions of
this Agreement. With respect to each Prime-based Advance, interest shall be
payable quarterly in arrears on the first Business Day of each March, June,
September and December, commencing on the first such Business Day following the
month during which such Advance is made, and at maturity (whether by
acceleration or otherwise). With respect to each Eurodollar-based Advance,
interest shall be payable on the last day of each Interest Period applicable
thereto. Notwithstanding the foregoing, from and after the occurrence of any
Event of Default and during the continuation thereof, the interest shall be
payable on demand, at a rate per annum equal to: (i) in the case of Prime-based
Advances, two percent (2%) above the Prime-based Rate; and (ii) in the case of a
Eurodollar-based Advance, two percent (2%) above the rate which would otherwise
be applicable under this Section 3.1 until the end of the then current Interest
Period, at which time such Advance shall bear interest at the rate provided for
in clause (i) of this Section 3.1. Interest on all Eurodollar-based Advances
shall be calculated on the basis of a 360-day year for the actual number of days
elapsed. Interest on all Prime-based Advances shall be calculated on the basis
of a 365 or 366 day year, as the case may be, for the actual number of days
elapsed. The interest rate with respect to any Prime-based Advance shall change
on the effective date of any change in the Prime-based Rate.

         3.2 Interest Periods. Each Interest Period for a Eurodollar-based
Advance shall commence on the date such Eurodollar-based Advance is made or is
converted from an Advance of another type pursuant to Section 3.3 hereof or on
the last day of the immediately preceding Interest Period for such
Eurodollar-based Advance, and shall end on the date one, two or three months
thereafter, as the Company may elect as set forth below, subject to the
following:

                  (i)      no Interest Period shall extend beyond the Maturity
                           Date; and

                  (ii)     any Interest Period which would otherwise end on a
                           day which is not a Business Day shall be extended to
                           the next succeeding Business Day unless the next
                           succeeding Business Day falls in another calendar
                           month, in which case, such Interest Period shall end
                           on the immediately preceding Business Day and when an
                           Interest Period begins on a day which has no
                           numerically corresponding day in the calendar month
                           during which such Interest Period is to end, it shall
                           end on the last Business Day of such calendar month.

The Company shall elect the initial Interest Period applicable to a
Eurodollar-based Advance by its Request for Advance given to the Bank pursuant
to Section 2.3 or by its notice of conversion given to the Bank pursuant to
Section 3.3, as the case may be. Provided that no Default or Event

                                       11
<PAGE>

of Default shall have occurred and be continuing, the Company may elect to
continue an Advance as a Eurodollar-based Advance by giving irrevocable written,
telephonic or telegraphic notice thereof to the Bank, before 12:00 noon on the
third Business Day before the last day of the then current Interest Period
applicable to such Eurodollar-based Advance, specifying the duration of the
succeeding Interest Period therefor. If the Bank does not receive timely notice
of the election and the Interest Period elected by the Company, the Company
shall be deemed to have elected to convert such Eurodollar-based Advance to a
Prime-based Advance at the end of the then current Interest Period.

         3.3 Conversion of Advances. Provided that no Default or Event of
Default shall have occurred and be continuing, the Company may, on any Business
Day, convert any outstanding Advance into an Advance of another type in the same
aggregate principal amount, provided that any conversion of a Eurodollar-based
Advance shall be made only on the last Business Day of the then current Interest
Period applicable to such Advance. If the Company desires to convert an Advance,
it shall give the Bank written, telephonic or telegraphic notice, specifying the
date of such conversion, the Advances to be converted, the type of Advance
elected and, if the conversion is into a Eurodollar-based Advance, the duration
of the first Interest Period therefor, which notice shall be given not later
than 12:00 noon on the third Business Day before the applicable date of
conversion. Each notice of conversion described in this Section 3.3 shall
constitute and include a certification by the Company as of the date hereof as
to the matters set forth in clause (f) of Section 2.3.

         3.4 Prime-based Advance in Absence of Election or Upon Default. If, (a)
as to any outstanding Eurodollar-based Advance, Bank has not received payment of
all outstanding principal and accrued interest on the last day of the Interest
Period applicable thereto, or does not receive a timely Request for Advance
meeting the requirements of Section 2 hereof with respect to the refunding or
conversion of such Advance, or (b) subject to Section 3.1 hereof, if on such day
a Default or an Event of Default shall have occurred and be continuing, then the
principal amount thereof which is not then prepaid in the case of a
Eurodollar-based Advance shall be converted automatically to a Prime-based
Advance and the Bank shall thereafter promptly notify the Company of said
action.

         4. SPECIAL PROVISIONS, CHANGES IN CIRCUMSTANCES AND YIELD PROTECTION.

         4.1 If Company makes any payment of principal with respect to any
Eurodollar-based Advance on any day other than the last day of the Interest
Period applicable thereto (whether voluntarily, by acceleration, or otherwise),
or if Company fails to borrow any Eurodollar-based Advance after notice has been
given by Company to Bank in accordance with the terms hereof requesting such
Advance, or if Company fails to make any payment of principal or interest when
due in respect of a Eurodollar-based Advance, Company shall reimburse Bank on
demand for any resulting loss, cost or expense incurred by Bank as a result
thereof, including, without limitation, any such loss, cost or expense incurred
in obtaining, liquidating, employing or redeploying deposits from third parties,
whether or not Bank shall have funded or committed to fund such Advance. Such
amount payable by Company to Bank may include, without limitation, an amount
equal to the excess, if any, of (a) the amount of interest which would have
accrued on the amount so prepaid, or not so borrowed, refunded or converted, for
the period from the date of

                                       12
<PAGE>

such prepayment or of such failure to borrow, refund or convert, through the
last day of the relevant Interest Period, at the applicable rate of interest for
said Advance(s) over (b) the amount of interest (as reasonably determined by
Bank) which would have accrued to Bank on such amount by placing such amount on
deposit for a comparable period with leading banks in the interbank eurodollar
market. Calculation of any amounts payable to Bank under this paragraph shall be
made as though Bank shall have actually funded or committed to fund the relevant
Eurodollar-based Advance through the purchase of an underlying deposit in an
amount equal to the amount of such Advance and having a maturity comparable to
the relevant Interest Period; provided, however, that Bank may fund any
Eurodollar-based Advance in any manner it deems fit and the foregoing
assumptions shall be utilized only for the purpose of the calculation of amounts
payable under this paragraph. Upon the written request of Company, Bank shall
deliver to Company a certificate setting forth the basis for determining such
losses, costs and expenses, which certificate shall be conclusively presumed
correct, absent manifest error.

         4.2 For any Interest Period for which the Applicable Interest Rate is
the Eurodollar-based Rate, if Bank shall designate a Eurodollar Lending Office
which maintains books separate from those of the rest of Bank, Bank shall have
the option of maintaining and carrying the relevant Advance on the books of such
Eurodollar Lending Office.

         4.3 If with respect to any Interest Period Bank reasonably determines
that, by reason of circumstances affecting the foreign exchange and interbank
markets generally, deposits in Eurodollars in the applicable amounts are not
being offered to the Bank for such Interest Period, then Bank shall forthwith
give notice thereof to the Company. Thereafter, until Bank notifies Company that
such circumstances no longer exist, the obligation of Bank to make
Eurodollar-based Advances, and the right of Company to convert an Advance to or
refund an Advance as a Eurodollar-based Advance shall be suspended.

         4.4 If, after the date hereof, the introduction or implementation of,
or any change in, any applicable law, rule or regulation or in the
interpretation or administration thereof by any governmental authority charged
with the interpretation or administration thereof, or compliance by Bank (or its
Eurodollar Lending Office) with any request or directive (whether or not having
the force of law) of any such authority, shall make it unlawful or impossible
for the Bank (or its Eurodollar Lending Office) to honor its obligations
hereunder to make or maintain any Advance, Bank shall forthwith give notice
thereof to Company. Thereafter (a) the obligations of Bank to make
Eurodollar-based Advances and the right of Company to convert an Advance or
refund an Advance as a Eurodollar-based Advance shall be suspended and
thereafter Company may select only the Prime-based Rate as the Applicable
Interest Rate, and (b) if Bank may not lawfully continue to maintain a
Eurodollar-based Advance to the end of the then current Interest Period
applicable thereto, the Prime-based Rate shall be the Applicable Interest Rate
for the remainder of such Interest Period.

         4.5 If the adoption or implementation after the date hereof, or any
change after the date hereof in, any applicable law, rule or regulation of any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by Bank (or its
Eurodollar Lending Office) with any request or directive (whether or not having
the force of law) made by any such authority, central bank or comparable agency
after the date hereof:

                                       13
<PAGE>

         (a)      shall subject Bank (or its Eurodollar Lending Office) to any
                  tax, duty or other charge with respect to any Advance or the
                  Note or shall change the basis of taxation of payments to Bank
                  (or its Eurodollar Lending Office) of the principal of or
                  interest on any Advance or the Note or any other amounts due
                  under this Agreement in respect thereof (except for changes in
                  the rate of tax on the overall net income of Bank or its
                  Eurodollar Lending Office imposed by any jurisdiction in which
                  Bank is organized or engaged in business); or

         (b)      shall impose, modify or deem applicable any reserve
                  (including, without limitation, any imposed by the Board of
                  Governors of the Federal Reserve System), special deposit or
                  similar requirement against assets of, deposits with or for
                  the account of, or credit extended by Bank (or its Eurodollar
                  Lending Office) or shall impose on Bank (or its Eurodollar
                  Lending Office) or the foreign exchange and interbank markets
                  any other condition affecting any Advance or the Note;

and the result of any of the foregoing is to increase the costs to Bank of
maintaining any part of the indebtedness hereunder or to reduce the amount of
any sum received or receivable by Bank under this Agreement or under the Note,
by an amount deemed by the Bank to be material, then Bank shall promptly notify
Company of such fact and demand compensation therefor and, within fifteen (15)
days after demand by Bank, Company agrees to pay to Bank such additional amount
or amounts as will compensate Bank for such increased cost or reduction. Bank
will promptly notify Company of any event of which it has knowledge which will
entitle Bank to compensation pursuant to this Section. Bank will deliver a
certificate to Company setting forth the basis for determining such additional
amount or amounts necessary to compensate Bank, which certificate shall be
conclusively presumed to be correct save for manifest error. Bank agrees that,
as promptly as practical after it becomes aware of the occurrence of any event
or the existence of a condition that will cause Bank to be entitled to
compensation under this Section, it will, to the extent not inconsistent with
Bank's internal policies, use reasonable efforts to make, fund or maintain any
affected Eurodollar-based Advance through another lending office of Bank if as a
result thereof the additional monies which would otherwise be required to be
paid in respect of such Eurodollar-based Advance would be materially reduced and
if, as determined by Bank, in its reasonable discretion, the making, funding or
maintaining of such Eurodollar-based Advance through such other lending office
would not materially adversely affect such Advance or Bank. Company shall pay
all reasonable expenses incurred by Bank in utilizing another lending office
pursuant to this Section.

         4.6 In the event that at any time after the date of this Agreement any
change in law such as described in Section 4.5 hereof, shall, in the reasonable
opinion of Bank require that the credit provided under Section 2 of this
Agreement be treated as an asset or otherwise be included for purposes of
calculating the appropriate amount of capital to be maintained by Bank or any
corporation controlling Bank and such change has or would have the effect of
reducing the rate of return on Bank's or Bank's parent's capital or assets as a
consequence of Bank's obligations hereunder to a level below that which Bank or
Bank's parent would have achieved but for such change, then Bank shall notify
Company and demand compensation therefor and, within five (5) days after demand
by Bank, Company agrees to pay to Bank such additional amount or amounts as will
compensate Bank for such reduction. Bank will promptly notify Company of any
event of

                                       14
<PAGE>

which it has knowledge which will entitle Bank to compensation pursuant to this
Section. A certificate of Bank setting forth the basis for determining such
additional amount or amounts necessary to compensate Bank shall be conclusively
presumed to be correct save for manifest error.

         5.7 The effectiveness of this Agreement and the Bank's obligation to
make the initial Advance under it are conditioned on the Bank's having received,
a certificate of an authorized officer of the Company dated the date of the

after due inquiry, (a) the conditions set forth in this Section 5 have been
satisfied; (b) the representations and warranties made by Loan Parties in this
Agreement or any of the other Loan Documents, shall have been true and correct
in all material respects when made and shall be true and correct in all material
respects on and as of the Restatement Date; (c) no Default or Event of Default
shall have occurred and be continuing; and (d) since March 31, 2006 or the date
of the most recent fiscal year end for which Bank has received the financial
statements required to be delivered under Section 7.1(a), whichever is later,
nothing shall have occurred which the Bank shall reasonably determine has had,
or could reasonably be expected to have, a Material Adverse Effect.

         5.8 Reserved.

         5.9 The obligations of the Bank to make Advances (including the initial
Advance) under this Agreement shall be subject to the occurrence of the
Effective Date and to the continuing conditions that:

         (a)      No Default or Event of Default shall exist as of the date of
                  the Advance;

         (b)      Company and its Subsidiaries shall be in compliance with the
                  Negative Covenants set forth in Section 8 at the time of and
                  after giving effect to the Advance, it being understood that
                  failure to so comply is not a Default or an Event of Default
                  so long as no Indebtedness is outstanding under this
                  Agreement; and

         (c)      Each of the representations and warranties contained in this
                  Agreement and in each of the other Loan Documents shall be
                  true and correct in all material respects as of the date of
                  the Advance as if made on and as of such date (other than any
                  representation or warranty that expressly speaks only as of a
                  different date).

         6. REPRESENTATIONS AND WARRANTIES

         Company represents and warrants and such representations and warranties
shall be deemed to be made on the date of this Agreement, the date of each
Request for Advance and the date of each Advance.

         6.1 Each Loan Party is a corporation (or other business entity) duly
organized and existing in good standing under the laws of the state of its
organization; each Loan Party is in good standing in each jurisdiction in which
it is required to be qualified to do business, except where the failure to be so
qualified would not have a Material Adverse Effect.

         6.2 Execution, delivery and performance of the applicable Loan
Documents to which any such Loan Party is a party, are within its powers, having
been duly authorized, are not in contravention of law or such Loan Party's
organizational documents or of the unwaived terms of any indenture, agreement or
undertaking to which such Loan Party is a party or by which it is bound, and do
not require the consent or approval of any governmental body, agency or
authority; and the Loan Documents and other documents and instruments required
under

                                       16
<PAGE>

thereunder, when issued and delivered, will be valid and binding on such
Loan Party in accordance with their terms.

         6.3 No litigation or other proceeding before any court or
administrative agency is pending, or to the knowledge of the officers of
Company, is threatened against any Loan Party, the outcome of which would
reasonably be expected to have a Material Adverse Effect.

         6.4 There are no security interests in, liens, mortgages, or other
encumbrances on any of Company's or any Subsidiary's assets, except to Bank or
as otherwise permitted by this Agreement.

         6.5 Neither Company nor any Subsidiary maintains or contributes to any
employee pension benefit plan subject to Title IV of ERISA, except those set
forth in attached Schedule 6.5 (each, a "Pension Plan"). There was no material
unfunded past service liability of any Pension Plan maintained by the Company as
of March 31, 2006, and there is no "accumulated funding deficiency" within the
meaning of Section 302 of ERISA, or any existing material liability with respect
to any Pension Plan owed to the Pension Benefit Guaranty Corporation ("PBGC") or
any successor thereto, except any funding deficiency for which an application to
the PBGC for waiver is pending or for which a waiver has been granted by the
PBGC.

         6.6 The financial statements of Company for the fiscal year ended March
31, 2006 as filed with the SEC and previously furnished by Company to Bank,
fairly present in all material respects the financial condition of Company and
its consolidated Subsidiaries as of such date; since said date there has been no
material adverse change in the financial condition of Company and its
consolidated Subsidiaries taken as a whole; to the best of the knowledge of
Company's officers, Company does not have any material contingent obligations
(including any liability for taxes) not disclosed by or reserved against those
financial statements, and at the present time there are no material unrealized
or anticipated losses from any present commitment of Company or any of its
Subsidiaries.

         6.7 All tax returns and tax reports of Company and its Consolidated
Subsidiaries required by law to have been filed have been duly filed or
extensions obtained, or requested within permitted deadlines and all taxes,
assessments and other governmental charges or levies (other than those presently
payable without penalty and those currently being contested in good faith for
which adequate reserves have been established) upon Company and its consolidated
Subsidiaries (or any of its or their properties) which are due and payable and
for which the failure to pay would materially adversely affect its business or
the value of its property or assets have been paid. The charges, accruals and
reserves on the books of Company in respect of the Federal income tax for all
periods are adequate in the opinion of Company.

         6.8 As of the date of this Agreement the Company has no Subsidiaries
other than those listed in Schedule 6.8.

         6.9 Except as set forth in Schedule 6.9 and except for such matters as
are not likely to have a Material Adverse Effect:

         (a)      all facilities and property owned or leased by the Loan
                  Parties or any of their respective Subsidiaries, are in
                  material compliance with all Environmental Laws;

                                       17
<PAGE>

         (b)      to the best knowledge of the Company, there have been no
                  unresolved and outstanding past, and there are no pending or
                  threatened

                  (i)      claims, complaints, notices or requests for
                           information received by any Loan Party or any of
                           their respective Subsidiaries with respect to any
                           alleged violation of any Environmental Law, or

                  (ii)     written complaints, notices or inquiries to any Loan
                           Party or any of their respective Subsidiaries
                           regarding potential liability of the Loan Parties or
                           any of their respective Subsidiaries under any
                           Environmental Law; and

         (c)      to the knowledge of the Company, no conditions exist at, on or
                  under any property now or previously owned or leased by the
                  Loan Parties or any of their respective Subsidiaries which,
                  with the passage of time, or the giving of notice or both,
                  would give rise to liability of the Loan Parties or any of
                  their respective Subsidiaries under any Environmental Law.

         6.10 Neither the Company nor any of its Subsidiaries is an "investment
company" within the meaning of the Investment Company Act of 1940, as amended.
Company is not engaged principally, or as one of its important activities,
directly or indirectly, in the business of extending credit for the purpose of
purchasing or carrying margin stock, and none of the proceeds of any of the
loans hereunder will be used, directly or indirectly, for any purpose which
would violate the provisions of Regulation U or X of the Board of Governors of
the Federal Reserve System. Terms for which meanings are provided in Regulation
U of the Board of Governors of the Federal Reserve System or any regulations
substituted therefor, as from time to time in effect, are used in this paragraph
with such meanings.

         7. AFFIRMATIVE COVENANTS

         Company covenants and agrees that it will and, as applicable, it will
cause its Subsidiaries to, so long as Bank may make any Advance under this
Agreement (regardless of whether any Indebtedness is outstanding under this
Agreement) and thereafter until the irrevocable final payment in full of the
Indebtedness and the performance by the Loan Parties of all other obligations
under this Agreement and the other Loan Documents:

signed by an officer of the Bank. No single or partial exercise of any right,
power or privilege hereunder, nor any delay in the exercise thereof, shall
preclude other or further exercise of its rights by Bank. No waiver of any Event
of Default shall extend to any other or further Event of Default. No forbearance
on the part of the Bank in enforcing any of its rights shall constitute a waiver
of any

                                       28

of its rights. Company expressly agrees that this Section 9.5 may not be waived
or modified by the Bank by course of performance, estoppel or otherwise.

         10.1 This Agreement shall be binding upon and shall inure to the
benefit of Company and Bank and their respective successors and assigns, except
that the credit provided for under this Agreement and no part thereof and no
obligation of Bank hereunder shall be assignable or otherwise transferable by
Company.

         10.2 Company shall pay all closing costs and expenses, including, by
way of description and not limitation, reasonable outside attorney fees (without
duplication of fees and expenses for the same services) and lien search fees
incurred by Bank in connection with the commitment, consummation and closing of
this Agreement or any subsequent amendment of this Agreement or any other Loan
Document. All of said amounts required to be paid by Company may, at Bank's
option if they remain unpaid for fifteen (15) days after payment therefore is
requested by Bank, be charged by Bank as an advance against the proceeds of the
Note. All costs, including reasonable attorney fees incurred by Bank in
protecting or enforcing any of its rights against Company or in defending Bank
from any claims or liabilities by any party or otherwise incurred by Bank in
connection with a Default or an Event of Default (including evaluation of
whether a Default or Event of Default exists or will exist) or the enforcement
of this Agreement or the related documents, including by way of description and
not limitation, such charges in any court or bankruptcy proceedings or arising
out of any claim or action by any person against Bank which would not have been
asserted were it not for Bank's relationship with Company hereunder, shall also
be paid by Company.

         10.3 Where the character or amount of any asset or liability or item of
income or expense is required to be determined or any consolidation or other
accounting computation is required to be made for the purposes of this
Agreement, it shall be done in accordance with GAAP.

         10.4 No delay or failure of Bank in exercising any right, power or
privilege hereunder shall affect such right, power or privilege, nor shall any
single or partial exercise thereof preclude any further exercise thereof, or the
exercise of any other power, right or privilege. The rights of Bank under this
Agreement are cumulative and not exclusive of any right or remedies which Bank
would otherwise have.

         10.5 Except as expressly provided otherwise in this Agreement, all
notices and other communications provided to any party hereto under this
Agreement shall be in writing and shall be given by personal delivery, by mail,
by reputable overnight courier, by telex or by facsimile and addressed or

delivered or if mailed and properly addressed with postage prepaid and sent by

if given to a reputable overnight courier and properly addressed, shall be
deemed given two (2) Business Days after the date on which it was sent, unless
it is actually received sooner by the named addressee; and any notice, if

shall be deemed given when received (answerback confirmed in the case of telexes
and receipt confirmed in the case of telecopies). Bank may, but shall not be
required to, take any action on the basis of any notice given to it by
telephone, but Company shall promptly confirm such notice in writing or by telex

         10.6 This Agreement and the Note have been delivered at Detroit,
Michigan, and shall be governed by and construed and enforced in accordance
with the laws of the State of Michigan. Whenever possible each
provision of this Agreement shall be interpreted in such manner as to be
effective and valid under applicable law, but if any provision of this Agreement
shall be prohibited by or invalid under applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this
Agreement. Company and Bank hereby irrevocably submit to the non-exclusive
jurisdiction of any United States Federal Court or Michigan state court sitting
in Detroit, Michigan in any action or proceeding arising out of or relating to
this Agreement or any of the Loan Documents and Company and Bank hereby
irrevocably agree that all claims in respect of such action or proceeding may be
heard and determined in any such United States Federal Court or Michigan state
court. Company irrevocably consents to the service of any and all process in any
such action or proceeding brought in any court in or of the State of Michigan by
the delivery of copies of such process to Company at its address specified on
the signature page hereto or by certified mail directed to such address or such
other address as may be designated by Company in a notice to the other parties
that complies as to delivery with the terms of Section 10.5. Nothing in this
Section shall affect the right of the Bank to serve process in any other manner
permitted by law or limit the right of the Bank to bring any such action or
proceeding against Company or any Subsidiary or any of its or their property in
the courts with subject matter jurisdiction of any other jurisdiction. Company
hereby irrevocably waives any objection to the laying of venue of any such suit
or proceeding in the above described courts.

                                       30
<PAGE>

         10.7 No amendments or waiver of any provisions of this Agreement nor
consent to any departure by Company therefrom shall in any event be effective
unless the same shall be in writing and signed by the Bank and the Company, and
then such amendment, waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given. No amendment, waiver or
consent with respect to any provision of this Agreement shall affect any other
provision of this Agreement.

         10.8 All sums payable by Company to Bank under this Agreement or the
other documents contemplated hereby shall be paid directly to Bank at its
principal office set forth in Section 10.5 hereof in immediately available
United States funds, without set off, deduction or counterclaim. In its sole
discretion, Bank may charge any and all deposit or other accounts (including
without limit an account evidenced by a certificate of deposit) of Company with
Bank for all or a part of any Indebtedness then due; provided, however, that
this authorization shall not affect Company's obligation to pay, when due, any
Indebtedness whether or not account balances are sufficient to pay amounts due.

         10.9 Any payment of the Indebtedness made by mail will be deemed
tendered and received only upon actual receipt by Bank at the address designated
for such payment, whether or not Bank has authorized payment by mail or any
other manner, and shall not be deemed to have been made in a timely manner
unless received on the date due for such payment, time being of the essence.
Company expressly assumes all risks of loss or liability resulting from
non-delivery or delay of delivery of any item of payment transmitted by mail or
in any other manner. Acceptance by Bank of any payment in an amount less than
the amount then due shall be deemed an acceptance on account only, and the
failure to pay the entire amount then due shall be and continue to be an Event
of Default, and at any time thereafter and until the entire amount then due has
been paid, Bank shall be entitled to exercise any and all rights conferred upon
it herein upon the occurrence of an Event of Default. Upon the occurrence and
during the continuance of a an Event of Default, Company waives the right to
direct the application of any and all payments at any time or times hereafter
received by Bank from or on behalf of Company. Upon the occurrence and during
the continuance of an Event of Default, Company agrees that Bank shall have the
continuing exclusive right to apply and to reapply any and all payments received
at any time or times hereafter against the Indebtedness in such manner as Bank
may deem advisable, notwithstanding any entry by Bank upon any of its books and
records. Company expressly agrees that to the extent that Bank receives any
payment or benefit and such payment or benefit, or any part thereof, is
subsequently invalidated, declared to be fraudulent or preferential, set aside
or is required to be repaid to a trustee, receiver, or any other party under any
bankruptcy act, state or federal law, common law or equitable cause, then to the
extent of such payment or benefit, the Indebtedness or part thereof intended to
be satisfied shall be revived and continued in full force and effect as if such
payment or benefit had not been made and, further, any such repayment by Bank,
to the extent that Bank did not directly receive a corresponding cash payment,
shall be added to and be additional Indebtedness payable upon demand by Bank.

         10.10 In the event Company's obligation to pay interest on the
principal balance of the Note is or becomes in excess of the maximum interest
rate which Company is permitted by law to contract or agree to pay, giving due
consideration to the execution date of this Agreement, then, in that event, the
rate of interest applicable shall be deemed to be immediately reduced to

                                       31
<PAGE>

such maximum rate and all previous payments in excess of such maximum rate shall
be deemed to have been payments in reduction of principal and not of interest.

         10.11 COMPANY AND BANK ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A
CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED. EACH PARTY, AFTER CONSULTING (OR
HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF THEIR CHOICE, KNOWINGLY
AND VOLUNTARILY, AND FOR THEIR MUTUAL BENEFIT WAIVES ANY RIGHT TO TRIAL BY JURY
IN THE EVENT OF LITIGATION REGARDING THE PERFORMANCE OR ENFORCEMENT OF, OR IN
ANY WAY RELATED TO, THIS AGREEMENT OR THE INDEBTEDNESS.

         10.12 This Agreement may be executed in several counterparts, and each
executed copy shall constitute an original instrument, but such counterparts
together shall constitute but one and the same instrument.

         10.13 This Agreement, the Note (if issued) and any Requests for Advance
hereunder, and the other Loan Documents contain the entire agreement of the
parties hereto, superseding all prior agreements, discussions and understandings
relating to the subject matter hereof, and none of the parties shall be bound by
anything not expressed in writing. In the event of any conflict between the
terms of this Agreement and the other Loan Documents, this Agreement shall
govern.

         10.14 In case any one or more of the obligations of Company under this
Agreement, the Note or any of the other Loan Documents shall be invalid, illegal
or unenforceable in any jurisdiction, the validity, legality and enforceability
of the remaining obligations of Company shall not in any way be affected or
impaired thereby, and such invalidity, illegality or unenforceability in one
jurisdiction shall not affect the validity, legality or enforceability of the
obligations of Company under this Agreement, the Note or any of the other Loan
Documents in any other jurisdiction.

         10.15 Each covenant hereunder shall be given independent effect
(subject to any exceptions stated in such covenant) so that if a particular
action or condition is not permitted by any such covenant (taking into account
any such stated exception), the fact that it would be permitted by an exception
to, or would be otherwise within the limitations of, another covenant shall not
avoid the occurrence of a Default or an Event of Default.

         10.16 All terms, covenants, agreements, representations and warranties
of Company or any party to any of the Loan Documents made herein or in any of
the Loan Documents or in any certificate, report, financial statement or other
document furnished by or on behalf of Company or any Subsidiary in connection
with this Agreement or any of the Loan Documents shall be deemed to have been
relied upon by the Bank, notwithstanding any investigation heretofore or
hereafter made by Bank, and those covenants and agreements of Company set forth
in Section 10.17 hereof (together with any other indemnities of Company or any
Subsidiary contained elsewhere in this Agreement or in any of the other Loan
Documents) shall survive the repayment in full of the Indebtedness and the
termination of the Commitment.

                                       32
<PAGE>

         10.17 (a) Company agrees to indemnify and hold Bank harmless from all
loss, cost, damage, liability or expenses, including reasonable outside
attorneys' fees and disbursements (but without duplication of fees and expenses
for the same services), incurred by Bank by reason of an Event of Default, or
enforcing the obligations of Company or any Subsidiary under this Agreement or
any of the other Loan Documents or in the prosecution or defense of any action
or proceeding concerning any matter growing out of or connected with this
Agreement or any of the Loan Documents, excluding, however, any loss, cost,
damage, liability or expenses arising solely as a result of the gross negligence
or willful misconduct of the party seeking to be indemnified under this Section
10.17(a).

         (b)      Company agrees to defend, indemnify and hold harmless Bank,
                  and its respective employees, agents, officers and directors
                  from and against any and all claims, demands, penalties,
                  fines, liabilities, settlements, damages, costs or expenses of
                  whatever kind or nature (including without limitation,
                  reasonable attorneys and consultants fees, investigation and
                  laboratory fees, environmental studies required by Bank in
                  connection with the violation of Environmental Laws, court
                  costs and litigation expenses, excluding however, those
                  arising solely as a result of the gross negligence or willful
                  misconduct of the Person seeking indemnification, as the case
                  may be) arising out of or related to (i) the presence, use,
                  disposal, release or threatened release of any Hazardous
                  Materials on, from or affecting any premises owned or occupied
                  by Company or any of their respective Subsidiaries in
                  violation of or non-compliance with applicable Environmental
                  Laws, (ii) any personal injury (including wrongful death) or
                  property damage (real or personal) arising out of or related
                  to such Hazardous Materials, (iii) any lawsuit or other
                  proceeding brought or threatened, settlement reached or
                  governmental order or decree relating to such Hazardous
                  Materials, (iv) if any Event of Default exists and remains
                  uncured, the cost of remediation or monitoring of all
                  Hazardous Materials in violation of or non-compliance with
                  applicable Environmental Laws from all or any portion of any
                  premises owned by Company or their respective Subsidiaries,
                  (v) if any Event of Default exists and remains uncured,
                  complying or coming into compliance with all Environmental
                  Laws and/or (vi) if any Event of Default exists and remains
                  uncured, any violation of Environmental Laws. The obligations
                  of Company under this Section 10.17(b) shall be in addition to
                  any and all other obligations and liabilities the Company may
                  have to Bank at common law or pursuant to any other agreement.

         10.18 The Company authorizes Bank, in its sole discretion, upon one
Business Day's notice to Company (or without notice if an Event of Default has
occurred and is continuing), to charge its general deposit account(s) maintained
at Bank for the amount of any principal, interest, or other amounts or costs due
under this Agreement when the same become due and payable under the terms of
this Agreement or the Note.

         10.19 (a) On the Restatement Date, the Prior Credit Agreement shall be
amended, restated and superseded in its entirety. The parties hereto acknowledge
and agree that (i) this Agreement, the Note, and the other Loan Documents
executed and delivered in connection herewith do not constitute a novation,
payment and reborrowing, or termination of the "Indebtedness" (as defined in the
Prior Credit Agreement) under the Prior Credit Agreement as

                                       33
<PAGE>

in effect prior to the Restatement Date; and (ii) such "Indebtedness" is in all
respects continuing with only the terms thereof being modified as provided in
this Agreement;

         (b) Notwithstanding the modifications effected by this Agreement of the
representations, warranties and covenants of Company contained in the Prior
Credit Agreement, Company acknowledges and agrees that any causes of action or
other rights created in favor of Bank and its successors arising out of the
representations and warranties of Company contained in or delivered (including
representations and warranties delivered in connection with the making of the
loans or other extensions of credit thereunder) in connection with the Prior
Credit Agreement shall survive the execution and delivery of this Agreement;
provided, however, that it is understood and agreed that Company's monetary
obligations under the Prior Credit Agreement in respect of the advances
thereunder are evidenced by this Agreement as provided herein. All
indemnification obligations of Company pursuant to the Prior Credit Agreement
(including any arising from a breach of the representations thereunder) shall
survive the amendment and restatement of the Prior Credit Agreement pursuant to
this Agreement.

         (c) On and after the Restatement Date, (i) each reference in the Loan
Documents to the "Credit Agreement", "thereunder", "thereof" or similar words
referring to the Credit Agreement shall mean and be a reference to this
Agreement and (ii) each reference in the Loan Documents to a "Note" shall mean
and be a Note as defined in this Agreement.

         WITNESS the due execution hereof as of the day and year first above
written.
