Business Day occurring after the Closing Date, voluntarily reduce the amount of
the Revolving Loan Commitment Amount, the Swingline Loan Commitment Amount or
the Letter of Credit Commitment Amount effective as of a Business Day specified
in writing by VHC; PROVIDED, HOWEVER, that all such reductions shall require at
least three Business Days' prior notice to the Administrative Agent and be
permanent, and any partial reduction of the Revolving Loan Commitment Amount
shall be in a minimum amount of $1,000,000 and in an integral multiple of
$100,000. Any optional or mandatory reduction of the Revolving Loan Commitment
Amount pursuant to the terms of this Agreement which reduces the Revolving Loan
Commitment Amount below the Swingline Loan Commitment Amount shall result in an
automatic and corresponding reduction of the Swingline Loan Commitment Amount to
an aggregate amount not in excess of the Revolving Loan Commitment Amount, as so
reduced, without any further action on the part of the Swingline Lender. Any
optional or mandatory reduction of the Revolving Loan Commitment Amount pursuant
to the terms of this Agreement which reduces the Revolving Loan Commitment
amount below the Letter of Credit Commitment Amount shall result in an automatic
and corresponding reduction of the Letter of Credit Commitment Amount to an
aggregate amount not in excess of the Revolving Loan Commitment amount, as so
reduced, without any further action on the part of any Issuer.

     SECTION 2.2.2. OPTIONAL INCREASE OF REVOLVING LOAN COMMITMENT AMOUNT.

     (a) VHC shall have the right on a one-time basis on any date on or after
the Closing Date and prior to the Commitment Termination Date to increase the
Revolving Loan Commitment Amount by an amount not to exceed $10,000,000 by
requesting that the Syndication Agent arrange for one or more existing Lenders
to increase the amount of their respective Revolving Loan Commitments or one or
more Eligible Assignees to become Revolving Lenders under this Agreement;
PROVIDED that (i) if VHC in good faith objects to the terms upon which the
Syndication Agent is willing to arrange such increase or the Syndication Agent
is unwilling or

                                      -37-
<Page>

unable after diligent effort to arrange such increase, VHC (but no Lender or
other financial institution) may arrange such increase; (ii) before offering
Revolving Loan Commitments to Eligible Assignees, VHC or the Syndication Agent,
as applicable, shall first offer the additional Revolving Loan Commitments to
existing Lenders on a pro rata basis; and (iii) no Lender shall at any time be
required to agree to increase its Revolving Loan Commitment or other obligations
hereunder.

     (b) Any increase in the aggregate Revolving Loan Commitment Amount pursuant
to CLAUSE (a) above shall be effective only upon the execution and delivery by
each Eligible Assignee or existing Lender, as the case may be, to VHC and the
Syndication Agent at least five Business Days before any such increase is to
become effective of an instrument reasonably satisfactory to VHC and the
Syndication Agent:

          (i) in the case of an Eligible Assignee, setting forth the amount of
     its Revolving Loan Commitment, the resulting Percentage and the date upon
     which its Revolving Loan Commitment and related Percentage are to become
     effective (the "COMMITMENT INCREASE DATE") and containing its agreement to
     become, and to perform all the obligations of, a Lender hereunder; and

          (ii) in the case of an existing Lender, setting forth the amount by
     which its Revolving Loan Commitment and related Percentage hereunder is to
     be increased and the Commitment Increase Date applicable thereto.

     (c) Any increase in the Revolving Loan Commitment Amount pursuant to CLAUSE
(a) above shall not be effective unless:

          (i) no Default or Event of Default shall have occurred and be
     continuing on the Commitment Increase Date;

          (ii) each of the representations and warranties of each Borrower and
     each other Obligor contained in this Agreement and the other Loan Documents
     shall be true and correct on and as of the Commitment Increase Date;

          (iii) each Lender (including each Eligible Assignee which becomes a
     Lender pursuant to this SECTION 2.2.3) shall have received a certificate of
     the secretary or assistant secretary of each Borrower as to the taking of
     any corporate action necessary in connection with such increase; and

          (iv) in the case of increases arranged by the Syndication Agent, the
     Borrowers shall have paid to the Syndication Agent such syndication,
     commitment or other upfront fees as shall be required by the Syndication
     Agent in connection with such increase of the Revolving Loan Commitment
     Amount.

     (d) From and after the Commitment Increase Date, the term "Lenders", as
used herein, shall include all Eligible Assignees which become Lenders pursuant
to this SECTION 2.2.2.

     (e) From and after the Commitment Increase Date, (A) the Revolving Loan
Commitment Amount shall be increased by the amount of the additional Revolving
Loan Commitments agreed

                                      -38-
<Page>

to be so provided, (B) the Percentages of the respective Lenders in respect of
the increased Revolving Loan Commitment Amount shall be proportionately adjusted
(PROVIDED, HOWEVER, that the amount equal to the adjusted Percentage of a Lender
multiplied by the Revolving Loan Commitment Amount as increased pursuant to
CLAUSE (A) may not exceed the amount equal to the Percentage of such Lender
immediately prior to any adjustment made pursuant to this CLAUSE (B) multiplied
by the Revolving Loan Commitment Amount immediately prior to the corresponding
increase thereof pursuant to CLAUSE (A) without the consent of such Lender) and
such adjustment shall be recorded in the Register and (C) at such time and in
such manner as the Borrowers and the Syndication Agent shall agree (it being
understood that the Borrowers and the Agents will use commercially reasonable
efforts to avoid the prepayment or assignment of any LIBO Rate Loan on a day
other than the last day of the Interest Period applicable thereto), the Lenders
shall assign and assume outstanding Revolving Loans and participations in
outstanding Letters of Credit so as to cause amounts of such Revolving Loans and
participations in Letters of Credit held by each Lender with a Percentage in
excess of zero to conform to its Percentage of the Revolving Loan Commitment.

     SECTION 2.3. BORROWING PROCEDURES. Loans (other than Swingline Loans) shall
be made by the Lenders in accordance with SECTION 2.3.1, and Swingline Loans
shall be made by the Swingline Lender in accordance with SECTION 2.3.2.

     SECTION 2.3.1. REVOLVING LOANS. By delivering a Borrowing Request to the
Administrative Agent on or before 12:00 Noon on a Business Day, any Borrower may
from time to time irrevocably request, on not less than one Business Day's
notice in the case of Base Rate Loans, or three Business Days' notice in the
case of LIBO Rate Loans, and in either case not more than five Business Days'
notice, that a Borrowing be made by the Revolving Lenders. Revolving Loans
(other than Revolving Loans made pursuant to SECTION 2.3.2(a)(ii), SECTION
2.3.2(b) or SECTION 2.6.2, which Revolving Loans shall be made in the amounts
specified therein) will be made in a minimum amount of $500,000 and integral
multiples of $100,000 or in an amount equal to the unused amount of the
Revolving Loan Commitment Amount. On the terms and subject to the conditions of
this Agreement, each Borrowing shall be comprised of the type of Loans, and
shall be made on the Business Day, specified in such Borrowing Request. Each
Lender that has a Commitment to make the Revolving Loans being requested shall
deposit with the Administrative Agent, on or before 11:00 a.m. on the date of
Borrowing, same day funds in an amount equal to such Lender's Percentage of the
requested Borrowing. Such deposit will be made to an account which the
Administrative Agent shall specify from time to time by notice to the Lenders.
To the extent funds are received from the Lenders, the Administrative Agent
shall make such funds available to the applicable Borrower by wire transfer to
the accounts such Borrower shall have specified in its Borrowing Request.
Neither the Administrative Agent's nor any Lender's obligation to make any Loan
shall be affected by any other Lender's failure to make any Loan.

     SECTION 2.3.2. SWINGLINE LOANS. (a) (i) By telephonic notice to the
Swingline Lender on or before 3:00 p.m. on a Business Day (followed on such day
by the delivery to the Swingline Lender of a confirming Borrowing Request), any
Borrower may from time to time irrevocably request that Swingline Loans be made
by the Swingline Lender in an aggregate minimum principal amount of $500,000 and
integral multiples of $100,000 or (ii) if on any day on which a Notice of Cash
Dominion is in effect or on which any Borrower shall have requested that

                                      -39-
<Page>

Swingline Loans be made available to such Borrower pursuant to this CLAUSE (ii),
Items are presented to the Depositary Bank for payment against the Operating
Account which Items, in the aggregate, would, if paid in full, cause the
Available Balance in the Operating Account on such day to be less than $0, such
presentation shall be deemed to be a request by the Borrowers for a Swingline
Loan on the date of such presentation in an amount equal to the amount (rounded
upward to the nearest $1,000) required to cause such Available Balance in the
Operating Account to equal $0. All Swingline Loans shall be made as Base Rate
Loans and shall not be entitled to be converted into LIBO Rate Loans. The
proceeds of each Swingline Loan requested pursuant to CLAUSE (i) above shall be
made available by the Swingline Lender to applicable Borrower by wire transfer
to the Operating Account or such other account as such Borrower shall have
specified in its notice therefor by the close of business on the Business Day
telephonic notice is received by the Swingline Lender. The proceeds of each
Swingline Loan deemed to be requested under CLAUSE (ii) above shall be disbursed
by the Swingline Lender by way of direct payment of the relevant Item or by way
of deposit to the Operating Account of the amount set forth in CLAUSE (ii)
above, as the case may be. Notwithstanding any contrary provision set forth in
this Agreement (including, without limitation, SECTION 5.2.1(b)), in the event
any Default or Event of Default occurs, the Swingline Lender shall, upon receipt
of a Notice of Borrowing pursuant to SECTION 2.3.2(a)(i) above or, if CLAUSE
(ii) above is then in effect, the presentation of an Item for payment from the
Operating Account in accordance with SECTION 2.3.2(a)(ii) above, make Swingline
Loans (such Swingline Loans being referred to herein as "DEFAULT LOANS") to the
applicable Borrower (which Swingline Loans shall be refunded by the Revolving
Lenders in accordance with SECTION 2.3.2(b) below regardless of the existence of
such Default or Event of Default) in an aggregate principal amount which, when
taken together with the aggregate amount of all cash and Cash Equivalent
Investments, permitted to be retained by the Borrowers and their respective
Subsidiaries in accordance with SECTION 3.1.1(d)(ii), shall not exceed
$2,500,000 at any time outstanding, the proceeds of which shall be used to pay
payroll and other operating expenses approved by the Administrative Agent.
Notwithstanding any contrary provision set forth in this Agreement, but in all
respects subject to SECTION 2.1.3(c), the Swingline Lender may, in its
discretion, upon receipt of a Notice of Borrowing pursuant to SECTION
2.3.2(a)(i) above or, if CLAUSE (ii) above is then in effect, the presentation
of an Item for payment from the Operating Account in accordance with SECTION
2.3.2(a)(ii) above, make Swingline Loans (such Swingline Loans being referred to
herein as "OVERADVANCE LOANS") to the Borrowers (which Swingline Loans shall be
refunded by the Revolving Lenders in accordance with SECTION 2.3.2(b) below
regardless of the existence of any Default or Event of Default) in an aggregate
principal amount not to exceed $2,500,000 at any time outstanding.

     (b) If (i) any Swingline Loan (including any Default Loan or Overadvance
Loan) shall be outstanding for more than four Business Days, (ii) any Swingline
Loan (including any Default Loan or Overadvance Loan) is or will be outstanding
on a date when a Borrower requests that a Revolving Loan be made, or (iii) any
Default shall occur and be continuing, then each Revolving Lender (other than
the Swingline Lender) irrevocably agrees that it will, at the request of the
Swingline Lender, make a Revolving Loan (which shall initially be funded as a
Base Rate Loan) in an amount equal to such Lender's Percentage of the aggregate
principal amount of all Swingline Loans then outstanding (such outstanding
Swingline Loans hereinafter referred to as the "REFUNDED SWINGLINE LOANS"). On
or before 11:00 a.m. on the first Business Day following receipt by each
Revolving Lender of a request to make Revolving Loans as provided in the
preceding sentence, each Revolving Lender shall deposit in an account specified
by the

                                      -40-
<Page>

Swingline Lender the amount so requested in same day funds and such funds shall
be applied by the Swingline Lender to repay the Refunded Swingline Loans. At the
time the Revolving Lenders make the above referenced Revolving Loans, the
Swingline Lender shall be deemed to have made, in consideration of the making of
the Refunded Swingline Loans, Revolving Loans in an amount equal to the
Swingline Lender's Percentage of the aggregate principal amount of the Refunded
Swingline Loans. Upon the making (or deemed making, in the case of the Swingline
Lender) of any Revolving Loans pursuant to this clause, the amount so funded
shall become outstanding as such Revolving Lender's Revolving Loan and shall no
longer be owed to the Swingline Lender as a Swingline Loan. All interest payable
with respect to any Revolving Loans made (or deemed made, in the case of the
Swingline Lender) pursuant to this clause shall be appropriately adjusted to
reflect the period of time during which the Swingline Lender had outstanding
Swingline Loans in respect of which such Revolving Loans were made. Each
Revolving Lender's obligation to make the Revolving Loans referred to in this
clause shall be absolute and unconditional and shall not be affected by any
circumstance, including (i) any set-off, counterclaim, recoupment, defense or
other right which such Lender may have against the Swingline Lender, any Obligor
or any Person for any reason whatsoever; (ii) the occurrence or continuance of
any Default; (iii) any adverse change in the condition (financial or otherwise)
of any Obligor; (iv) the acceleration or maturity of any Obligations or the
termination of any Commitment after the making of any Swingline Loan; (v) any
breach of any Loan Document by any Person or any amendment or other modification
to this Agreement or any other Loan Document; or (vi) any other circumstance,
occurrence or event whatsoever, whether or not similar to any of the foregoing.

     SECTION 2.4. CONTINUATION AND CONVERSION ELECTIONS. By delivering a
Continuation/ Conversion Notice to the Administrative Agent on or before 12:00
noon on a Business Day, the applicable Borrower may from time to time
irrevocably elect, on not less than one Business Day's notice in the case of a
conversion of LIBO Rate Loans to Base Rate Loans, or three Business Days' notice
in the case of a continuation of LIBO Rate Loans for an additional Interest
Period or a conversion of Base Rate Loans to LIBO Rate Loans, and in either case
not more than five Business Days' notice, that all, or any portion in an
aggregate minimum amount of $500,000 and integral multiples of $100,000 of the
Revolving Loans outstanding to such Borrower be, in the case of Base Rate Loans,
converted into LIBO Rate Loans or be, in the case of LIBO Rate Loans, converted
into Base Rate Loans or continued as LIBO Rate Loans (in the absence of delivery
of a Continuation/Conversion Notice with respect to any LIBO Rate Loan at least
three Business Days (but not more than five Business Days) before the last day
of the then current Interest Period with respect thereto, such LIBO Rate Loan
shall, on such last day, automatically convert to a Base Rate Loan); PROVIDED,
HOWEVER, that (x) each such conversion or continuation shall be pro rated among
the applicable outstanding Loans to such Borrower of all Lenders that have made
such Loans, and (y) no portion of the outstanding principal amount of any Loans
may be continued as, or be converted into, LIBO Rate Loans when any Event of
Default has occurred and is continuing.

     SECTION 2.5. FUNDING. Each Lender may, if it so elects, fulfill its
obligation to make, continue or convert LIBO Rate Loans hereunder by causing one
of its foreign branches or affiliates (or an international banking facility
created by such Lender) to make or maintain such LIBO Rate Loan; PROVIDED,
HOWEVER, that such LIBO Rate Loan shall nonetheless be deemed to have been made
and to be held by such Lender, and the obligation of the Borrowers to repay

                                      -41-
<Page>

such LIBO Rate Loan shall nevertheless be to such Lender for the account of such
foreign branch, affiliate or international banking facility; and PROVIDED,
FURTHER, HOWEVER, that, except for purposes of determining whether any such
increased costs are payable by a Borrower, such Lender shall cause such foreign
branch, affiliate or international banking facility to comply with the
applicable provisions of CLAUSE (b) of SECTION 4.6 with respect to such LIBO
Rate Loan. In addition, the Borrowers hereby consent and agree that, for
purposes of any determination to be made for purposes of SECTIONS 4.1, 4.2, 4.3
or 4.4, it shall be conclusively assumed that each Lender elected to fund all
LIBO Rate Loans by purchasing Dollar deposits in its LIBOR Office's interbank
eurodollar market.

     SECTION 2.6. ISSUANCE PROCEDURES, ETC. (a) On the Closing Date, each Issuer
that has issued an Existing Letter of Credit shall be deemed, without further
action by any party hereto, to have sold to each Revolving Lender, and each such
Revolving Lender shall be deemed, without further action by any party hereto, to
have purchased from each such Issuer, without recourse or warranty, an undivided
participation interest in its Percentage of such Existing Letter of Credit and
the related Letter of Credit Outstandings (although any fronting fee payable
under SECTION 3.3.2 shall be payable directly to the Administrative Agent for
the accounting of each applicable Issuer, and the Lenders (other than such
Issuer) shall have no right to receive any portion of such fronting fee) and any
security therefore or guaranty pertaining thereto. On and after the Closing
Date, each Existing Letter of Credit shall constitute a Letter of Credit for all
purposes hereof.

     (b) On or after the Closing Date, by delivering to the Administrative Agent
an Issuance Request on or before 12:00 noon on a Business Day, any Borrower may
from time to time irrevocably request on not less than three nor more than ten
Business Days' notice, in the case of an initial issuance of a Letter of Credit,
and not less than three Business Days' prior notice, in the case of a request
for the extension of the Stated Expiry Date of an outstanding Letter of Credit
(in each case, unless a shorter notice period is agreed to by the Issuer, in its
sole discretion), that an Issuer issue, or extend the Stated Expiry Date of, a
Letter of Credit in such form as may be requested by such Borrower and approved
by such Issuer (such approval not to be unreasonably withheld), solely for the
purposes described in SECTION 7.1.7. Each Letter of Credit shall by its terms be
stated to expire on a date (its "STATED EXPIRY DATE") no later than the earlier
to occur of (i) the fifth Business Day immediately preceding the date specified
in CLAUSE (ii) of the definition of "Commitment Termination Date" or (ii)
(unless otherwise agreed to by an Issuer, in its sole discretion), one year from
the date of its issuance (subject to automatic renewal provisions); PROVIDED,
HOWEVER, that, notwithstanding the terms of this CLAUSE (ii), a Letter of Credit
may, if required by the beneficiary thereof, contain automatic renewal
provisions pursuant to which the Stated Expiry Date shall be automatically
extended (to a date not beyond the date specified in CLAUSE (i) above), unless
notice to the contrary shall have been given to the beneficiary prior to the
then existing Stated Expiry Date in accordance with the terms specified in such
Letter of Credit by the applicable Issuer or the account party of such Letter of
Credit (which notice by the account party shall also have been provided to the
applicable Issuer in writing). Each Issuer will make available to the
beneficiary thereof the original of the Letter of Credit which it issues.

     SECTION 2.6.1. OTHER LENDERS' PARTICIPATION. Upon the issuance of each
Letter of Credit, and without further action, each Revolving Lender (other than
such Issuer) shall be deemed to have irrevocably purchased, to the extent of its
Percentage, a participation interest in

                                      -42-
<Page>

such Letter of Credit (including the Contingent Liability and any Reimbursement
Obligation with respect thereto), and such Revolving Lender shall, to the extent
of its Percentage, be responsible for reimbursing within one Business Day the
Issuer for Reimbursement Obligations which have not been reimbursed by the
Borrowers in accordance with SECTION 2.6.3. In addition, such Revolving Lender
shall, to the extent of its Percentage, be entitled to receive a ratable portion
of the Letter of Credit fees payable pursuant to SECTION 3.3.2 with respect to
each Letter of Credit (other than the issuance fees payable to an Issuer of such
Letter of Credit pursuant to the last sentence of SECTION 3.3.2) and of interest
payable pursuant to SECTION 3.2 with respect to any Reimbursement Obligation. To
the extent that any Revolving Lender has reimbursed any Issuer for a
Disbursement, such Lender shall be entitled to receive its ratable portion of
any amounts subsequently received (from the Borrowers or otherwise) in respect
of such Disbursement.

     SECTION 2.6.2. DISBURSEMENTS. An Issuer will notify the applicable Borrower
and the Administrative Agent promptly of the presentment for payment of any
drawing under Letter of Credit issued by such Issuer, together with notice of
the date (the "DISBURSEMENT DATE") such payment shall be made (each such
payment, a "DISBURSEMENT"). Subject to the terms and provisions of such Letter
of Credit and this Agreement, the applicable Issuer shall make such payment to
the beneficiary (or its designee) of such Letter of Credit. Prior to 12:30 p.m.
on the first Business Day following the Disbursement Date (the "DISBURSEMENT DUE
DATE"), the applicable Borrower will reimburse the Administrative Agent (any
such reimbursement obligation to be a joint and several obligation of the
Borrowers), for the account of the applicable Issuer, for all amounts which such
Issuer has disbursed under such Letter of Credit, together with interest thereon
at a rate per annum equal to the rate per annum then in effect for Base Rate
Loans (with the then Applicable Margin for Revolving Loans accruing on such
amount) pursuant to SECTION 3.2 for the period from the Disbursement Date
through the date of such reimbursement; PROVIDED, HOWEVER, that, if no Default
shall have then occurred and be continuing, unless the applicable Borrower has
notified the Administrative Agent no later than one Business Day prior to the
Disbursement Due Date that it will reimburse the Issuer for the applicable
Disbursement, then the amount of the Disbursement shall be deemed to be a
Borrowing of Revolving Loans by the applicable Borrower constituting Base Rate
Loans and, following the giving of notice thereof by the Administrative Agent to
the Lenders, each Lender (other than the Issuer) will deliver to the Issuer on
the Disbursement Due Date immediately available funds in an amount equal to such
Lender's Percentage of such Borrowing. Each conversion of Disbursement amounts
into Revolving Loans shall constitute a representation and warranty by each
Borrower that on the date of the making of such Revolving Loans all of the
statements set forth in SECTION 5.2.1 are true and correct. Without limiting in
any way the foregoing and notwithstanding anything to the contrary contained
herein or in any separate application for any Letter of Credit, each Borrower
hereby acknowledges and agrees that it shall jointly and severally be obligated
to reimburse the applicable Issuer upon each Disbursement of a Letter of Credit,
and it shall be deemed to be the obligor for purposes of each such Letter of
Credit issued hereunder (whether the account party on such Letter of Credit is
such Borrower or any other Borrower).

     SECTION 2.6.3. REIMBURSEMENT. The joint and several obligation (a
"REIMBURSEMENT OBLIGATION") of the Borrowers under SECTION 2.6.2 to reimburse an
Issuer with respect to each Disbursement (including interest thereon) not
converted into a Base Rate Loan pursuant to

                                      -43-
<Page>

SECTION 2.6.2 and, upon the failure of the Borrowers to reimburse an Issuer,
each Revolving Lender's obligation under SECTION 2.6.1 to reimburse an Issuer or
fund its Percentage of any Disbursement converted into a Base Rate Loan, shall
be absolute and unconditional under any and all circumstances and irrespective
of any setoff, counterclaim or defense to payment which any Borrower or such
Revolving Lender, as the case may be, may have or have had against such Issuer
or any Lender, including any defense based upon the failure of any Disbursement
to conform to the terms of the applicable Letter of Credit (if, in such Issuer's
good faith opinion, such Disbursement is determined to be appropriate) or any
non-application or misapplication by the beneficiary of the proceeds of such
Letter of Credit; PROVIDED, HOWEVER, that after paying in full its Reimbursement
Obligation hereunder, nothing herein shall adversely affect the right of any
Borrower or such Lender, as the case may be, to commence any proceeding against
an Issuer for any wrongful Disbursement made by such Issuer under a Letter of
Credit as a result of acts or omissions constituting gross negligence or willful
misconduct on the part of such Issuer.

     SECTION 2.6.4. DEEMED DISBURSEMENTS. Upon the occurrence and during the
continuation of any Event of Default of the types described in CLAUSES (b)
through (d) of SECTION 8.1.9 with respect to the Parent or any Borrower or upon
notification by the Administrative Agent (acting at the direction of the
Required Lenders) to the Borrowers of their respective obligations under this
Section, following the occurrence and during the continuation of any other Event
of Default, (i) the aggregate Stated Amount of all Letters of Credit shall,
without demand upon or notice to any Borrower or any other Person, be deemed to
have been paid or disbursed by the Issuers of such Letters of Credit
(notwithstanding that such amount may not in fact have been paid or disbursed),
and (ii) the Borrowers shall be immediately obligated, jointly and severally, to
reimburse the Issuers for the amount deemed to have been so paid or disbursed by
such Issuers. Amounts payable by the Borrowers pursuant to this Section shall be
deposited in immediately available funds with the Administrative Agent and held
as collateral security for the Reimbursement Obligations. When all Events of
Default giving rise to the deemed disbursements under this Section have been
cured or waived the Administrative Agent shall return to VHC, on behalf of the
Borrowers, all amounts then on deposit with the Administrative Agent pursuant to
this Section which have not been applied to the satisfaction of the
Reimbursement Obligations.

     SECTION 2.6.5. NATURE OF REIMBURSEMENT OBLIGATIONS. Each Borrower and the
Parent and, to the extent set forth in SECTION 2.6.1, each Revolving Lender
shall assume all risks of the acts, omissions or misuse of any Letter of Credit
by the beneficiary thereof. No Issuer (except to the extent of its own gross
negligence or willful misconduct) shall be responsible for:

          (a) the form, validity, sufficiency, accuracy, genuineness or
     legal effect of any Letter of Credit or any document submitted by any
     party in connection with the application for and issuance of a Letter
     of Credit, even if it should in fact prove to be in any or all
     respects invalid, insufficient, inaccurate, fraudulent or forged;

          (b) the form, validity, sufficiency, accuracy, genuineness or
     legal effect of any instrument transferring or assigning or purporting
     to transfer or assign a Letter of Credit or the rights or benefits
     thereunder or the proceeds thereof in whole or in part, which may
     prove to be invalid or ineffective for any reason;

                                      -44-
<Page>

          (c) failure of the beneficiary to comply fully with conditions
     required in order to demand payment under a Letter of Credit;

          (d) errors, omissions, interruptions or delays in transmission or
     delivery of any messages, by mail, cable, telegraph, telex or
     otherwise; or

          (e) any loss or delay in the transmission or otherwise of any
     document or draft required in order to make a Disbursement under a
     Letter of Credit.

None of the foregoing shall affect, impair or prevent the vesting of any of the
rights or powers granted to any Issuer or any Revolving Lender hereunder. In
furtherance and not in limitation or derogation of any of the foregoing, any
action taken or omitted to be taken by an Issuer in good faith (and not
constituting gross negligence or willful misconduct) shall be binding upon each
Obligor and each such Lender Party, and shall not put such Issuer under any
resulting liability to any Obligor or any Lender Party, as the case may be.

     SECTION 2.7. NOTES. (a) The Borrowers agree that, upon the request to the
Administrative Agent by any Lender, the Borrowers will execute and deliver to
such Lender a Note evidencing the Loans made by, and payable to the order of,
such Lender in a maximum principal amount equal to such Lender's Percentage of
the original applicable Commitment Amount. The Borrowers hereby irrevocably
authorize each Lender to make (or cause to be made) appropriate notations on the
grid attached to such Lender's Note (or on any continuation of such grid), which
notations, if made, shall evidence, INTER ALIA, the date of, the outstanding
principal amount of, the interest rate and Interest Period applicable to the
Loans evidenced thereby and the Borrower to whom each such Loan was made. Such
notations shall, to the extent not inconsistent with notations made by the
Administrative Agent in the Register, constitute prima facie evidence and shall
be binding on each Obligor absent manifest error; PROVIDED, HOWEVER, that the
failure of any Lender to make any such notations shall not limit or otherwise
affect any Obligations of any Obligor.

     (b) Each Borrower hereby designates the Administrative Agent to serve as
its agent, solely for the purpose of this clause, to maintain a register (the
"REGISTER") on which the Administrative Agent will record each Lender's
Commitment, the Loans made by each Lender to each Borrower and each repayment in
respect of the principal amount of the Loans, annexed to which the
Administrative Agent shall retain a copy of each Lender Assignment Agreement
delivered to the Administrative Agent pursuant to SECTION 11.10. Failure to make
any recordation, or any error in such recordation, shall not affect any
Obligor's Obligations. The entries in the Register shall constitute prima facie
evidence and shall be binding on the Obligors absent manifest error, and the
Borrowers, the Administrative Agent and the Lenders shall treat each Person in
whose name a Loan is registered (or, if applicable, to which a Note has been
issued) as the owner thereof for the purposes of all Loan Documents,
notwithstanding notice or any provision herein to the contrary. Any assignment
or transfer of a Commitment or the Loans made pursuant hereto shall be
registered in the Register only upon delivery to the Administrative Agent of a
Lender Assignment Agreement that has been executed by the requisite parties
pursuant to SECTION 11.10. No assignment or transfer of a Lender's Commitment or
Loans shall be effective unless such assignment or transfer shall have been
recorded in the Register by the Administrative Agent as provided in this
Section.

     SECTION 2.8. NOTICE OF CASH DOMINION. The parties hereto agree that (i)
upon the occurrence and during the continuance of any Default or Event of
Default or (ii) at any time at which the Excess Availability has been less than
$10,000,000 for any period of 5 consecutive Business Days, the Administrative
Agent may (and at the request of the Required Lenders shall) give a Notice of
Cash Dominion (with a copy to VHC), which Notice of Cash Dominion shall remain
in full force and effect until revoked or terminated in writing by the
Administrative Agent. When all Defaults and Events of Default, whether giving
rise to such Notice of Cash Dominion or otherwise, have been cured or waived and
the Excess Availability has been greater than or equal to $10,000,000 for a
period of 5 consecutive Business Days, the Administrative Agent, at the request
of VHC, shall terminate the effectiveness of such Notice of Cash Dominion, and
such Notice of Cash Dominion shall thereafter cease to be effective.

                                   ARTICLE III
                   REPAYMENTS, PREPAYMENTS, INTEREST AND FEES

     SECTION 3.1. REPAYMENTS AND PREPAYMENTS; APPLICATION. Each Borrower agrees
that the Loans shall be repaid and prepaid pursuant to the following terms.

     SECTION 3.1.1. REPAYMENTS AND PREPAYMENTS. The Borrowers shall be
obligated, jointly and severally, to repay in full the unpaid principal amount
of each Loan on the Commitment Termination Date. Prior thereto, payments and
prepayments of the Loans shall or may be made as set forth below.

          (a) From time to time on any Business Day, a Borrower may make a
     voluntary prepayment, in whole or in part, of the outstanding
     principal amount of any:

               (i)  Revolving Loans; PROVIDED, HOWEVER, that (x) any such
          prepayment of Revolving Loans shall be made PRO RATA among the
          Revolving Loans of all Lenders of the same type and, if
          applicable, having the same Interest Period; (y) all such
          voluntary prepayments shall require at least one but no more than
          five Business Days' prior notice to the Administrative Agent; and
          (z) all such voluntary partial prepayments shall be in an
          aggregate minimum amount of $100,000 and integral multiples
          thereof; and

               (ii) Swingline Loans; PROVIDED, HOWEVER, that (x) all such
          voluntary prepayments shall require prior telephonic notice to
          the Swingline Lender on or before 1:00 p.m. on the day of such
          prepayment (such notice to be confirmed in writing within 24
          hours thereafter); and (y) all such voluntary partial prepayments
          shall be in an aggregate minimum amount of $50,000 and integral
          multiples of $10,000.

          (b) On each date when the aggregate Revolving Outstandings
     (excluding Overadvance Loans) exceed the Borrowing Base Amount
     (including as a result of a reduction in the Borrowing Base Amount in
     effect on such date), the Borrowers shall make a mandatory prepayment
     of Revolving Loans or Swingline Loans (or

                                      -46-
<Page>

     both) and, if necessary, Cash Collateralize Letter of Credit Outstandings,
     in an aggregate amount equal to such excess. On the 10th day immediately
     following the date of any Overadvance Loan, the Borrowers shall, unless the
     aggregate Revolving Outstandings (including any Overadvance Loans) are then
     equal to or less than the Borrowing Base Amount in effect on such date,
     repay such Overadvance Loan in full.

          (c) Concurrently with the receipt by the Parent or any of its
     Subsidiaries of any Net Proceeds, the Borrowers shall be obligated,
     jointly and severally, to make mandatory prepayments of the Loans, as
     set forth below, and each such prepayment shall be applied as set
     forth in SECTION 3.1.2:

               (i) NET EQUITY PROCEEDS. In the event the Parent or any of its
          Subsidiaries receives any Net Equity Proceeds, VHC shall deliver to
          the Administrative Agent a calculation of the amount of such Net
          Equity Proceeds, and the Borrowers shall make a mandatory prepayment
          of the Loans in an amount equal to the Specified Percentage of such
          Net Equity Proceeds; PROVIDED, HOWEVER, that Net Equity Proceeds
          (other than the Specified Percentage of Net Equity Proceeds from an
          Initial Public Offering) may be used for one or more Permitted
          Purposes and, to the extent such proceeds are so used in all cases as
          provided in the definition of "Permitted Purpose", the Borrowers shall
          not be required to prepay Loans or Cash Collateralize Letter of Credit
          Outstanding pursuant to this SECTION 3.1.1(c).

               (ii) NET DISPOSITION PROCEEDS. In the event the Parent or any of
          its Subsidiaries receives any Net Disposition Proceeds, VHC shall
          deliver to the Administrative Agent a calculation of the amount of
          such Net Disposition Proceeds, and, to the extent the aggregate amount
          of such proceeds received by the Parent and its Subsidiaries in
          connection with any single transaction or series of related
          transactions exceeds $2,000,000, the Borrowers shall within 30 days
          after receipt of such Net Disposition Proceeds, be obligated, jointly
          and severally, to make a mandatory prepayment of the Loans in an
          amount equal to 100% of such Net Disposition Proceeds; PROVIDED,
          HOWEVER, that, upon written notice by VHC to the Administrative Agent
          not less than 30 days following receipt of any Net Disposition
          Proceeds, an aggregate amount of up to $25,000,000 (as such amount may
          be increased with the consent of the Required Lenders) of such
          proceeds over the term of this Agreement may be retained by VHC and
          its Subsidiaries (and be excluded from the prepayment requirements of
          this clause) if (x) VHC informs the Administrative Agent in such
          notice of its good faith intention to apply (or cause one or more of
          its Subsidiaries to apply) such Net Disposition Proceeds to the
          acquisition of other assets or properties consistent with the
          businesses permitted to be conducted pursuant to SECTION 7.2.1
          (including by way of merger or Investment), and (y) within 365 days
          following the receipt of such Net Disposition Proceeds, such proceeds
          are applied or

                                      -47-
<Page>

          committed to such acquisition. The amount of such Net Disposition
          Proceeds unused or uncommitted after such 365-day period shall be
          applied to the Loans as set forth in SECTION 3.1.2. At any time
          after receipt of any such Net Disposition Proceeds in excess of
          $2,000,000 but prior to the application thereof to a mandatory
          prepayment or the acquisition of other assets or properties as
          described above, the Borrowers shall prepay Loans pursuant to
          SECTION 3.1.1(a) (with the amount of any such prepayment to
          continue to be considered to be Net Disposition Proceeds for
          purposes of this Agreement and the other Loan Documents) or, to
          the extent it elects not to so prepay Loans, upon written demand
          by the Administrative Agent (in its reasonable discretion) to the
          Borrowers, deposit an amount equal to such Net Disposition
          Proceeds into a cash collateral account maintained with (and
          reasonably satisfactory to) the Administrative Agent for the
          benefit of the Secured Parties (and over which the Administrative
          Agent shall have sole dominion and control) pending such
          application as a prepayment or to be released as requested by VHC
          in respect of such acquisition. Amounts deposited in such cash
          collateral account shall be invested in Cash Equivalent
          Investments, as directed by VHC.

               (iii) NET CASUALTY PROCEEDS. In the event the Parent or any
          of its Subsidiaries receives any Net Casualty Proceeds, VHC shall
          deliver to the Administrative Agent a calculation of the amount
          of such Net Casualty Proceeds and, to the extent the aggregate
          amount of such proceeds received by the Parent and its
          Subsidiaries in respect of any single Casualty Event or series of
          related Casualty Events exceeds $2,000,000, the Borrowers shall,
          within 60 days after the receipt of such Casualty Proceeds be
          obligated, jointly and severally, to make a mandatory prepayment
          of the Loans in an amount equal to 100% of such Net Casualty
          Proceeds; PROVIDED, HOWEVER, that, upon written notice by VHC to
          the Administrative Agent not less than 60 days following receipt
          of any Net Casualty Proceeds, up to 100% of such proceeds may be
          retained by VHC and its Subsidiaries (and be excluded from the
          prepayment requirements of this clause) if (x) VHC informs the
          Administrative Agent in such notice of its good faith intention
          to apply (or cause one or more of its Subsidiaries to apply) such
          Net Casualty Proceeds to the repair or replacement of the assets
          or properties which have been lost or damaged as a result of the
          Casualty Event giving rise to such Net Casualty Proceeds or to
          the acquisition of other property or assets consistent with the
          businesses permitted to be conducted under SECTION 7.2.1, and (y)
          within 365 days following the receipt of such Net Casualty
          Proceeds such proceeds are applied or committed to such repair,
          replacement or acquisition. The amount of any such Net Casualty
          Proceeds unused or uncommitted after such 365-day period shall be
          applied to the Loans as set forth in SECTION 3.1.2. At any time
          after receipt of any such Net Casualty Proceeds in excess of
          $2,000,000 but prior to the application thereof to a mandatory
          prepayment or the repair, replacement or acquisition of lost or

                                      -48-
<Page>

          damaged assets or property or other property or assets as
          described above, the Borrowers shall prepay Loans pursuant to
          SECTION 3.1.1(a) (with the amount of any such prepayment to be
          continued to be Net Casualty Proceeds for purposes of this
          Agreement and the other Loan Documents) or, to the extent it
          elects not to so prepay Loans, upon written demand by the
          Administrative Agent (in its reasonable discretion) to the
          Borrowers, deposit an amount equal to such Net Casualty Proceeds
          into a cash collateral account maintained with (and reasonably
          satisfactory to) the Administrative Agent for the benefit of the
          Secured Parties (and over which the Administrative Agent shall
          have sole dominion and control) pending such application as a
          prepayment or to be released as requested by VHC in respect of
          such repair, replacement or acquisition. Amounts deposited in
          such cash collateral account shall be invested in Cash Equivalent
          Investments, as directed by the VHC.

               (iv) NET DEBT PROCEEDS. In the event the Parent or any of its
          Subsidiaries receives any Net Debt Proceeds, the Borrowers shall be
          obligated, jointly and severally, to make a mandatory prepayment of
          the Loans in an amount equal to 100% of such Net Debt Proceeds.

          (d) MANDATORY REPAYMENTS FROM COLLECTION ACCOUNTS.

               (i) DEPOSITS OF PROCEEDS TO COLLECTION ACCOUNTS. At all times
          during which a Notice of Cash Dominion is in effect, the Obligors
          shall instruct all Account Debtors and other Persons obligated in
          respect of Accounts to make all payments in respect of the Accounts
          directly to one or more Collection Accounts. So long as no Event of
          Default has occurred and is continuing, all such payments shall be
          deposited in a Collection Account. In addition to the foregoing, each
          Borrower agrees that if the proceeds of any Accounts shall be received
          by it or by any of the other Obligors at any time during which a
          Notice of Cash Dominion is in effect, such Borrower shall, and shall
          cause each of the other Obligors to, as promptly as possible deposit
          such proceeds in a Collection Account. Until so deposited, all such
          proceeds shall be held in trust by such Obligors for the
          Administrative Agent on behalf of the Secured Parties and shall not be
          commingled with any other funds or property of such Obligors. Each
          Borrower hereby irrevocably authorizes and empowers the Administrative
          Agent, its officers, employees and authorized agents at any time
          during which a Notice of Cash Dominion is in effect, to endorse and
          sign its name or the name of any other Obligor on all checks, drafts,
          money orders or other media of payment so delivered, and such
          endorsements or assignments shall, for all purposes, be deemed to have
          been made by the applicable Obligor prior to any endorsement or
          assignment thereof by the Administrative Agent. The Administrative
          Agent may use any convenient or customary means for the purpose of
          collecting such checks, drafts, money orders or other media of
          payment.

          Notice of Dominion is in effect, (A) the aggregate Available Balance
          of all Disbursement Accounts in excess of an aggregate amount equal to

          Event of Default shall have occurred and be continuing, $5,000,000,
          (y) if Excess Availability on such date exceeds $5,000,000 and an
          Event of Default shall have occurred and be continuing, $2,500,000 or
          (z) if Excess Availability on such date is less than or equal to
          $5,000,000, $0 (PROVIDED that the limitations set forth in this CLAUSE
          (ii) shall not affect or impair any rights or remedies of the
          Administrative Agent under the Pledge and Security Agreement or any
          other Loan Document if an Event of Default has occurred and is
          continuing), shall be transferred by the Borrowers and their
          Subsidiaries into one or more Collection Accounts, (B) the aggregate
          Available Balance of all Collection Accounts shall be transferred by
          the respective banks maintaining such Collection Accounts into the
          Concentration Account and (C) following the transfers referred to in
          CLAUSE (B) above, to the extent necessary to pay in full the Loans
          and/or to Cash Collateralize in full all Letter of Credit
          Outstandings, the Available Balance in the Concentration Account shall

     obligated, jointly and severally, to repay all the Loans, unless,
     pursuant to SECTION 8.3, only a portion of all the Loans has been
     accelerated (in which case the portion so accelerated shall be so
     repaid).

Period at the interest rate determined as applicable to such LIBO Rate Loan.

     SECTION 3.2.2. POST-DEFAULT RATES. After the date any principal amount of
any Loan shall have become due and payable (whether on the applicable Stated
Maturity Date, upon acceleration or otherwise), or any other monetary Obligation
of any Borrower shall have become due and payable, the Borrowers shall pay, but
only to the extent permitted by law, interest (after as well as before judgment)
on such amounts at a rate per annum equal to the rate that would otherwise be

     otherwise have been payable pursuant to CLAUSE (c), on the date of
     such conversion.

Interest accrued on Loans or other monetary Obligations after the date such
amount is due and payable (whether on the stated maturity date, upon
acceleration or otherwise) shall be payable upon demand.

suspended by reason of the Borrowers' inability to satisfy any condition of
ARTICLE V) commencing on the Closing Date and continuing to but excluding the
Commitment Termination Date, a commitment fee at a rate equal to 0.625% per
annum, on such Lender's Percentage of the difference on such day of the

obligations of the Borrowers under SECTIONS 7.1.12 and 7.1.13 have been
satisfied in full and (ii) the 60th day immediately following the Closing Date,
the commitment fee shall not accrue or otherwise be payable with respect to that

Borrowing Base Amount solely as a result of the exclusion of the orderly
liquidation value of real property assets of the Borrowers from the Borrowing

PP&E". All commitment fees payable pursuant to this Section shall be calculated
on a year comprised of 360 days and shall be paid by the Borrowers in arrears on
each Quarterly Payment Date, commencing with the first Quarterly Payment Date on
or following June 30, 2002, and on the Commitment Termination Date.

Applicable Margin for such day for Revolving Loans maintained as LIBO Rate
Loans, in the case of standby Letters of Credit or (B) the Applicable Margin for
such day for Revolving Loans maintained as LIBO Rate Loans less 50 basis points,
in the case of trade Letters of Credit, in each case on the Stated Amount of
each such Letter of Credit, such fees being payable quarterly in arrears on each

                                   ARTICLE IV
                     CERTAIN LIBO RATE AND OTHER PROVISIONS

     SECTION 4.1. LIBO RATE LENDING UNLAWFUL. If any Lender shall determine
(which determination shall, upon notice thereof to the Borrowers and the
Administrative Agent, be prima facie evidence thereof and shall be binding on
the Borrowers absent manifest error) that the introduction of or any change in
or in the interpretation of any law, in each case after the later of (i) the
Closing Date and (ii) the date upon which such Lender shall have become a Lender
hereunder (unless, in the case of this CLAUSE (ii), such introduction or change
shall have similarly affected substantially all of the other Lenders) makes it
unlawful, or any Governmental Authority asserts, after such date, that it is
unlawful, for such Lender to make or continue any Loan as, or

                                      -52-
<Page>

to convert any Loan into, a LIBO Rate Loan, the obligations of such Lender to
make or continue any Loan as a LIBO Rate Loan, or convert any Loan into a LIBO
Rate Loan shall, upon such determination, forthwith be suspended until such
Lender shall notify the Administrative Agent that the circumstances causing such
suspension no longer exist (with the date of such notice being the
"REINSTATEMENT DATE"), and (a) all LIBO Rate Loans previously made by such
Lender shall automatically convert into Base Rate Loans at the end of the then
current Interest Periods with respect thereto or sooner, if required by such law
or assertion and (b) all Loans thereafter made by such Lender and outstanding
prior to the Reinstatement Date shall be made as Base Rate Loans, with interest
thereon being payable on the same date that interest is payable with respect to
the corresponding Borrowing of LIBO Rate Loans made by Lenders not so affected.

     SECTION 4.2. DEPOSITS UNAVAILABLE. If the Administrative Agent shall have
determined that

          (a) Dollar deposits in the relevant amount and for the relevant
     Interest Period are not available to it in its relevant market; or

          (b) by reason of circumstances affecting it's relevant market,
     adequate means do not exist for ascertaining the interest rate
     applicable hereunder to LIBO Rate Loans;

then, upon notice from the Administrative Agent to the Borrowers and the
Lenders, the obligations of all Lenders under SECTION 2.3 and SECTION 2.4 to
make or continue any Loans as, or to convert any Loans into, LIBO Rate Loans
shall forthwith be suspended until the Administrative Agent shall notify the
Borrowers and the Lenders that the circumstances causing such suspension no
longer exist.

     SECTION 4.3. INCREASED LIBO RATE LOAN COSTS, ETC. The Borrowers agree,
jointly and severally, to reimburse each Lender for any increase in the cost to
such Lender of, or any reduction in the amount of any sum receivable by such
Lender in respect of, such Lender Commitments and the making of Credit
Extensions hereunder related to the making, continuing or maintaining (or of its
obligation to make, continue or maintain) any Loans as, or of converting (or of
its obligation to convert) any Loans into, LIBO Rate Loans) that arise as a
result of any change in, or the introduction, adoption, effectiveness,
interpretation, reinterpretation or phase-in after the later of (i) the Closing
Date and (ii) the date upon which such Lender shall have become a Lender
hereunder (unless, in the case of this CLAUSE (ii), such change, introduction,
adoption, effectiveness, interpretation, reinterpretation or phase-in shall have
similarly effected substantially all of the Lenders) of, any law or regulation,
directive, guideline, decision or request (whether or not having the force of
law) of any Governmental Authority, except for such changes with respect to
increased capital costs and taxes which are governed by SECTIONS 4.5 and 4.6,
respectively. Each affected Lender shall promptly notify the Administrative
Agent and the Borrowers in writing of the occurrence of any such event, stating
in reasonable detail the reasons therefor and the additional amount required
fully to compensate such Lender for such increased cost or reduced amount. Such
additional amounts shall be payable by the Borrowers directly to such Lender
within five days of its receipt of such notice, and such notice shall be prima
facie evidence thereof and shall be binding upon the Borrowers absent manifest
error.

                                      -53-

     SECTION 4.4. FUNDING LOSSES. In the event any Lender shall incur any loss
or expense (including any loss or expense incurred by reason of the liquidation
or reemployment of deposits or other funds acquired by such Lender to make or
continue any portion of the principal amount of any Loan as, or to convert any
portion of the principal amount of any Loan into, a LIBO Rate Loan, but
excluding loss of margin after the date of any such conversion, repayment,
prepayment or failure to borrow, continue or convert) as a result of

          (a) any conversion or repayment or prepayment of the principal
     amount of any LIBO Rate Loan on a date other than the scheduled last
     day of the Interest Period applicable thereto, whether pursuant to
     ARTICLE III or otherwise;

          (b) any Loans not being borrowed as LIBO Rate Loans in accordance
     with the Borrowing Request therefor; or

          (c) any Loans not being continued as, or converted into, LIBO
     Rate Loans in accordance with the Continuation/Conversion Notice
     therefor;

then, upon the written notice of such Lender to the Borrowers (with a copy to
the Administrative Agent), the Borrowers shall, within five days of its receipt
thereof, pay directly to such Lender such amount as will (in the reasonable
determination of such Lender) reimburse such Lender for such loss or expense.
Such written notice (which shall include calculations thereof in reasonable
detail) shall be prima facie evidence thereof and shall be binding upon the
Borrowers absent manifest error.

     SECTION 4.5. INCREASED CAPITAL COSTS. If any change in, or the
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any law or regulation, directive, guideline, decision or request
(whether or not having the force of law) of any Governmental Authority after the
later of (i) the Closing Date and (ii) the date upon which the applicable Lender
becomes a Lender hereunder (unless, in the case of this CLAUSE (ii) such change,
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in shall have similarly effected substantially all of the Lenders) affects
or would affect the amount of capital required or expected to be maintained by
any Lender Party or any Person controlling such Lender Party, and such Lender
Party determines (in good faith but in its sole and absolute discretion) that as
a result thereof the rate of return on its or such controlling Person's capital
as a consequence of the Commitments or the Credit Extensions made, or the
Letters of Credit participated in, by such Lender Party is reduced to a level
below that which such Lender Party or such controlling Person could have
achieved but for the occurrence of any such circumstance, then upon notice from
time to time by such Lender Party to the Borrowers, the Borrowers shall be
obligated within five days following receipt of such notice to pay directly to
such Lender Party additional amounts sufficient to compensate such Lender Party
or such controlling Person for such reduction in rate of return. A statement of
such Lender Party as to any such additional amount or amounts (which shall
include calculations thereof in reasonable detail) shall be prima facie evidence
thereof and shall be binding upon the Borrowers absent manifest error. In
determining such amount, such Lender Party may use any method of averaging and
attribution that it (in its sole and absolute discretion) shall deem applicable;
PROVIDED, HOWEVER, that such Lender may not impose materially greater costs on
the Borrowers than on similarly situated borrowers by virtue of any such
averaging or attribution method.

                                      -54-

     SECTION 4.6. TAXES. (a) All payments by any Obligor of principal of, and
interest on, the Loans and all other amounts payable hereunder or under any
other Loan Document (including Reimbursement Obligations, fees and expenses)
shall be made free and clear of and without deduction for any present or future
income, excise, stamp or franchise taxes and other taxes, fees, duties,
withholdings or other charges of any nature whatsoever imposed by any taxing
authority from or through which payments originate or are made or deemed made by
or to any Obligor, but excluding (i) any income, excise, stamp or franchise
taxes and other similar taxes, fees, duties, withholdings or other charges
imposed on any Lender or either of the Agents by a jurisdiction under the laws
of which such Lender or Agent is organized or in which its principal executive
office is located, or otherwise as a result of a present or former connection
between the applicable lending office (or office through which it performs any
of its actions as Lender or Agent) of such Lender or Agent and the jurisdiction
of the governmental authority imposing such tax or any political subdivision or
taxing authority thereof or therein (other than any such connection arising
solely from such Agent or such Lender having executed, delivered or performed
its obligations or received a payment under, or taken any action to enforce,
this Agreement and any Note) or (ii) any income, excise, stamp or franchise
taxes and other similar taxes, fees, duties, withholdings or other charges to
the extent that they are in effect and would apply as of the date any Person
becomes a Lender or Assignee Lender, or as of the date that any Lender changes
its applicable lending office, to the extent such taxes become applicable as a
result of such change (other than a change in an applicable lending office made
pursuant to SECTION 4.10 below) (such non-excluded items being called "TAXES").
In the event that any withholding or deduction from any payment to be made by
any Obligor hereunder is required in respect of any Taxes pursuant to any
applicable law, rule or regulation, then (i) the applicable Obligor will pay
directly to the relevant taxing authority the full amount required to be so
withheld or deducted, (ii) the applicable Obligor will promptly forward to the
Administrative Agent an official receipt or other documentation available to
such Obligor reasonably satisfactory to the Administrative Agent evidencing such
payment to such authority, and (iii) the Borrowers shall be obligated, jointly
and severally, to pay to the Administrative Agent for the account of the Lenders
such additional amount or amounts as is necessary to ensure that the net amount
actually received by each Lender will equal the full amount such Lender would
have received had no such withholding or deduction been required; PROVIDED,
HOWEVER, that the Obligors shall not be required to pay any such additional
amounts in respect of amounts payable to any Lender that is not organized under
the laws of the United States or a state thereof to the extent that the related
tax is imposed (or an exemption therefrom is not available) as a result of such
Lender or Agent failing to comply with the requirements of CLAUSE (b) of
SECTION 4.6.

     Moreover, if any Taxes are directly asserted against either of the Agents
or any Lender with respect to any payment received by such Agents or such Lender
hereunder, such Agent or such Lender may pay such Taxes and the Borrowers will
promptly pay to such Person such additional amount (including any penalties,
interest or expenses) as is necessary in order that the net amount received by
such Person (including any Taxes on such additional amount) shall equal the
amount of such Taxes paid by such Person; PROVIDED, HOWEVER, that the Borrowers
shall not be obligated to make payment to the Lenders or the Agents (as the case
may be) pursuant to this sentence in respect of penalties or interest
attributable to any Taxes, if written demand therefor has not been made by such
Lenders or the Agents within 60 days from the date on which such Lenders or the
Agents knew of the imposition of Taxes by the relevant taxing authority or for
any additional imposition which may arise from the failure of the Lenders or the
Agents to apply

                                      -55-
<Page>

payments in accordance with the tax law after the Obligors have made the
payments required hereunder; PROVIDED, FURTHER that the Borrowers shall not be
required to pay any such additional amounts in respect of any amounts payable to
any Lender or any Agent (as the case may be) that is not organized under the
laws of the United States or a state thereof to the extent the related Tax is
imposed as a result of such Lender failing to comply with the requirements of
CLAUSE (b) of SECTION 4.6. After the Lenders or the Agents (as the case may be)
learn of the imposition of Taxes, such Lenders and the Agents will act in good
faith to notify the Borrowers of their obligations hereunder as soon as
reasonably possible.

     If any Obligor fails to pay any Taxes when due to the appropriate taxing
authority or fails to remit to the Administrative Agent, for the account of the
respective Lenders, the required receipts or other required documentary
evidence, the Borrowers, jointly and severally, shall indemnify the Lenders for
any incremental Taxes, interest or penalties that may become payable by any
Lender as a result of any such failure.

     (b) Each Non-U.S. Lender shall, (i) on or prior to the date of the
execution and delivery of this Agreement, in the case of each Lender listed on
the signature pages hereof, or, in the case of an Assignee Lender, on or prior
to the date it becomes a Lender, execute and deliver to the Borrowers and the
Administrative Agent, two or more (as the Borrowers or the Agents may reasonably
request) United States Internal Revenue Service Forms W-8ECI or Forms W-8BEN (or
successor forms) establishing the Lender's exemption from United States federal
withholding tax, or, solely if such Lender is claiming exemption from United
States withholding tax under Section 871(h) or 881(c) of the Code with respect
to payments of "portfolio interest", United States Internal Revenue Service
Forms W-8BEN and a certificate signed by a duly authorized officer of such
Lender representing that such Lender is not a "bank" within the meaning of
Section 881(c)(3)(A) of the Code, or such other form or documents (or successor
forms or documents), appropriately completed, establishing that payments to such
Lender are exempt from withholding or deduction of United States federal
withholding taxes; and (ii) deliver to the Borrowers and the Administrative
Agent two further copies of any such form or documents on or before the date
that any such forms or document expires or becomes obsolete and after the
occurrence of any event requiring a change in the most recent such forms or
document previously delivered by it to the Borrowers. Each Lender and each Agent
agrees, to the extent reasonable and without material cost to it, to provide to
the Borrowers and the Administrative Agent such other applicable forms or
certificates as would reduce or eliminate any Tax otherwise applicable.

     (c) If the Borrowers determine in good faith that a reasonable basis exists
for contesting the imposition of a Tax with respect to a Lender or either of the
Agents, the relevant Lender or Agent, as the case may be, shall cooperate with
the Borrowers in challenging such Tax at the Borrowers' expense if requested by
the Borrowers; PROVIDED, HOWEVER, that nothing in this SECTION 4.6 shall require
any Lender or Agent to submit to the Borrowers or any person any tax returns or
any part thereof, or to prepare or file any tax returns other than as such
Lender or Agent at its sole discretion shall determine.

     (d) If a Lender or an Agent shall receive a refund (including any offset or
credit from a taxing authority (as a result of any error in the imposition of
Taxes by such taxing authority)) of any Taxes paid by a Borrower pursuant to
CLAUSE (a) above, such Lender or such Agent (as the

                                      -56-
<Page>

case may be) shall promptly pay such Borrower the amount so received, with
interest from the taxing authority with respect to such refund, net of any tax
liability incurred by such Lender or Agent that is attributable to the receipt
of such refund and such interest.

     (e) Each Lender and each Agent agrees, to the extent reasonable and without
material cost to it, to cooperate with the Borrowers to minimize any amounts
payable by the Borrowers under this SECTION 4.6; PROVIDED, HOWEVER, that nothing
in this SECTION 4.6 shall require any Lender or Agent to take any action which,
in the sole discretion of such Lender or Agent, is inconsistent with its
internal policy and legal and regulatory restrictions.

     (f) If the Borrowers are required to pay additional amounts to or for
the account of any Lender or Agent pursuant to CLAUSE (a) above as a result
of a change of law occurring after the date hereof, then such Lender or
Agent, at the request of the Borrowers, will change the jurisdiction of its
applicable lending office (or office through which it performs any of its
actions as Agent) if such change (i) would eliminate or reduce any such
additional payment which may thereafter accrue and (ii) is not, in the good
faith determination of such Lender or Agent, otherwise disadvantageous to
such Lender or Agent.

     SECTION 4.7. PAYMENTS, COMPUTATIONS, ETC. Unless otherwise expressly
provided in a Loan Document, all payments by the Borrowers pursuant to each Loan
Document shall be made to the Administrative Agent for the PRO RATA account of
the Lender Parties entitled to receive such payment. All payments shall be made
without setoff, deduction or counterclaim not later than 12:30 p.m. on the date
due in same day or immediately available funds to such account as the
Administrative Agent shall specify from time to time by notice to the Borrowers.
Funds received after that time may be deemed by the Administrative Agent to have
been received by the Administrative Agent on the next succeeding Business Day.
Each Borrower shall, at the time it makes any payment under this Agreement,
specify to the Administrative Agent the Loan, Letter of Credit, fees or other
amounts payable by such Borrower hereunder to which such payment is to be
applied (and if it fails to specify or if such application would be inconsistent
with the terms hereof, the Administrative Agent shall, subject to SECTION 4.8,
distribute such payment to the Lender Parties in such manner as the
Administrative Agent may deem appropriate). The Administrative Agent shall
promptly remit in same day funds to each Lender Party its share, if any, of such
payments received by the Administrative Agent for the account of such Lender
Party. All interest and fees shall be computed on the basis of the actual number
of days (including the first day but excluding the last day) occurring during
the period for which such interest or fee is payable over a year comprised of
360 days (or, in the case of interest on a Base Rate Loan (calculated at other
than the Federal Funds Rate), 365 days or, if appropriate, 366 days). Payments
due on other than a Business Day shall (except as otherwise required by
CLAUSE (c) of the definition of "Interest Period") be made on the next
succeeding Business Day and such extension of time shall be included in
computing interest and fees in connection with that payment.

     SECTION 4.8. SHARING OF PAYMENTS. If any Lender Party shall obtain any
payment or other recovery (whether voluntary, involuntary, by application of
setoff or otherwise) on account of any Credit Extension or Reimbursement
Obligation (other than pursuant to the terms of SECTIONS 4.3, 4.4, 4.5 or 4.6)
in excess of its PRO RATA share of payments obtained by all Lender Parties, such
Lender Party shall purchase from the other Lender Parties such participations in

                                      -57-
<Page>

Credit Extensions made by them as shall be necessary to cause such purchasing
Lender Party to share the excess payment or other recovery ratably (to the
extent such other Lender Parties were entitled to receive a portion of such
payment or recovery) with each of them; PROVIDED, HOWEVER, that if all or any
portion of the excess payment or other recovery is thereafter recovered from
such purchasing Lender Party, the purchase shall be rescinded and each Lender
Party which has sold a participation to the purchasing Lender Party shall repay
to the purchasing Lender Party the purchase price to the ratable extent of such
recovery together with an amount equal to such selling Lender Party's ratable
share (according to the proportion of (a) the amount of such selling Lender
Party's required repayment to the purchasing Lender Party in respect of such
recovery TO (b) the total amount so recovered from the purchasing Lender Party)
of any interest or other amount paid or payable by the purchasing Lender Party
in respect of the total amount so recovered. Each Borrower agrees that any
Lender Party purchasing a participation from another Lender Party pursuant to
this Section may, to the fullest extent permitted by law, exercise all its
rights of payment (including pursuant to SECTION 4.9) with respect to such
participation as fully as if such Lender Party were the direct creditor of the
applicable Borrower in the amount of such participation. If under any applicable
bankruptcy, insolvency or other similar law any Lender Party receives a secured
claim in lieu of a setoff to which this Section applies, such Lender Party
shall, to the extent practicable, exercise its rights in respect of such secured
claim in a manner consistent with the rights of the Lender Parties entitled
under this Section to share in the benefits of any recovery on such secured
claim.

     SECTION 4.9. SETOFF. Each Lender Party shall, upon the occurrence and
during the continuance of any Default described in CLAUSES (b) through (d) of
SECTION 8.1.9 with respect to the Parent or any Borrower or, with the consent of
the Required Lenders, upon the occurrence and during the continuance of any
other Event of Default, to the fullest extent permitted by law, have the right
to appropriate and apply to the payment of the Obligations to it then due, and
(as security for such Obligations) each Borrower and the Parent hereby grant to
each Lender Party a continuing security interest in, any and all balances,
credits, deposits, accounts or moneys of such Borrower or the Parent then or
thereafter maintained with such Lender Party; PROVIDED, HOWEVER, that any such
appropriation and application shall be subject to the provisions of SECTION 4.8.
Each Lender Party agrees promptly to notify the applicable Borrower or the
Parent, as applicable, and the Administrative Agent after any such setoff and
application made by such Lender Party; PROVIDED, HOWEVER, that the failure to
give such notice shall not affect the validity of such setoff and application.
The rights of each Lender Party under this Section are in addition to other
rights and remedies (including other rights of setoff under applicable law or
otherwise) which such Lender Party may have.

     SECTION 4.10. MITIGATION. Each Lender agrees that if it makes any demand
for payment under SECTIONS 4.3, 4.5 or 4.6, or if its obligation to fund LIBO
Rate Loans is suspended under SECTION 4.1, it will use reasonable efforts
(consistent with its internal policy and legal and regulatory restrictions and
so long as such efforts would not be disadvantageous to it, as determined in its
sole discretion) to designate a different lending office if the making of such a
designation would reduce or obviate the need for the Borrowers to make payments
under SECTION 4.3, 4.5 or 4.6. or would alleviate or reduce the effect of any
adoption or change described in SECTION 4.1.

                                      -58-
<Page>

     SECTION 4.11. REPLACEMENT OF LENDERS. Each Lender hereby severally agrees
as set forth in this Section. If any Lender (a "SUBJECT LENDER") (a) makes
demand upon any Borrower for (or if any Borrower is otherwise required to pay)
amounts pursuant to SECTION 4.3, 4.5 or 4.6, (b) gives notice pursuant to
SECTION 4.1 requiring a conversion of such Subject Lender's LIBO Rate Loans to
Base Rate Loans or suspending such Lender's obligation to make Loans as, or to
convert Loans into, LIBO Rate Loans, (c) becomes a Non-Consenting Lender or (d)
becomes a Defaulting Lender, VHC may, within 180 days of receipt by it of such
demand or notice (or the occurrence of such other event causing any Borrower to
be required to pay such compensation) or within 180 days of such Lender becoming
a Non-Consenting Lender or a Defaulting Lender, as the case may be, give notice
(a "REPLACEMENT NOTICE") in writing to the Administrative Agent and such Subject
Lender of its intention to replace such Subject Lender with a financial
institution (a "REPLACEMENT LENDER") designated in such Replacement Notice. If
the Administrative Agent shall, in the exercise of its reasonable discretion and
within 30 days of its receipt of such Replacement Notice, notify VHC and such
Subject Lender in writing that the designated financial institution is
satisfactory to the Administrative Agent (such consent not to be unreasonably
withheld or delayed and not to be required where the Replacement Lender is
already a Lender), then such Subject Lender shall, subject to the payment of any
amounts due pursuant to SECTION 4.4, assign, in accordance with SECTION 11.10,
all of its Commitments, Loans, Notes (if applicable) and other rights and
obligations under this Agreement and all other Loan Documents (including,
without limitation, Reimbursement Obligations) to such designated financial
institution; PROVIDED, HOWEVER, that (i) such assignment shall be without
recourse, representation or warranty and shall be on terms and conditions
reasonably satisfactory to such Subject Lender and such designated financial
institution and (ii) the purchase price paid by such designated financial
institution shall be in the amount of such Subject Lender's Loans and its
Percentage of outstanding Reimbursement Obligations, together with all accrued
and unpaid interest and fees in respect thereof, plus all other amounts
(including the amounts demanded and unreimbursed under SECTIONS 4.3, 4.5 and
4.6), owing to such Subject Lender hereunder. Upon the effective date of an
assignment described above, if requested by the applicable Replacement Lender,
the Borrowers shall issue a replacement Note or Notes, as the case may be, to
such designated financial institution or Replacement Lender, as applicable, and
such institution shall become a "Lender" for all purposes under this Agreement
and the other Loan Documents.

                                    ARTICLE V

Transaction.

proceeding or labor controversy (i) except as disclosed in ITEM 6.7 of the

their respective properties, businesses, assets or revenues, which

                                      -66-

occurred with respect to any action, suit, investigation, litigation, proceeding
or labor controversy disclosed in ITEM 6.7 of the Disclosure Schedule

     SECTION 6.8. SUBSIDIARIES. Nether the Parent nor any Borrower has any
Subsidiaries, except those Subsidiaries which are identified in ITEM 6.8 of the

100% of all issued and outstanding shares of Capital Securities of each Borrower
and each Subsidiary Guarantor.

     SECTION 6.9. OWNERSHIP OF PROPERTIES. Except to the extent that the failure
to do so could not reasonably be expected to have a Material Adverse Effect, the
Parent and each of its Subsidiaries owns (i) in the case of owned real property,
good and valid fee title to, (ii) in the case of owned personal property, good

     SECTION 6.11. PENSION AND WELFARE PLANS. During the
twelve-consecutive-month period prior to the Closing Date, no steps have been
taken to terminate any Pension Plan, and no contribution failure has occurred
with respect to any Pension Plan sufficient to give rise to a Lien under
Section 302(f) of ERISA which, in either case is reasonably expected to
lead to a liability of such Pension Plan in excess of $3,000,000. No
condition exists or event or transaction has occurred with respect to any
Pension Plan which could reasonably be expected to result in the incurrence
by the Parent or any member of the Controlled Group of any material
liability, fine or penalty other than such condition, event or transaction
which would not reasonably be expected to have a Material Adverse Effect.
Except as disclosed in ITEM 6.11 of the Disclosure Schedule or otherwise
approved by the Agents, since the date of the last financial statements of
VHC delivered pursuant to CLAUSE (a) or (b) of SECTION 7.1.1, neither the

     the National Priorities List pursuant to CERCLA, on the CERCLIS or on

from time to time in effect, are used in this Section with such meanings.

     SECTION 6.15. ISSUANCE OF SENIOR NOTES; STATUS OF OBLIGATIONS AS SENIOR
INDEBTEDNESS, ETC. The Subordination Provisions contained in or related to the

any applicable state law respecting fraudulent transfers or fraudulent
conveyances. On the Closing Date, after giving effect to the Transaction, each

all papers and documents (if any) relating thereto: (i) represent legal, valid
and binding obligations of the respective Account Debtor, subject to adjustments

Parent and each Borrower will, and will cause each of their respective
Subsidiaries to, preserve and maintain its legal existence (except as otherwise
permitted by SECTION 7.2.10), and, except to the extent that the failure to do
so could not reasonably be expected to have a Material Adverse Effect, comply in

including the payment (before the same become delinquent) of all taxes imposed
upon such Person or upon its property except to the extent being diligently

reserves in accordance with GAAP have been set aside on the books of the
Borrowers or their respective Subsidiaries, as applicable.

     SECTION 7.1.3. MAINTENANCE OF PROPERTIES. Except to the extent that the
failure to do so could not reasonably be expected to have a Material Adverse

properties) in good repair, working order and condition (ordinary wear and tear
excepted), and make necessary repairs, renewals and replacements so that its
business may be properly conducted at all times, unless such Borrower determines
in good faith that the continued maintenance of any of its properties is no
longer economically desirable, and in each case the failure to do so could not
reasonably be expected to have a Material Adverse Effect.

     SECTION 7.1.4. INSURANCE. The Parent and each Borrower will, and will cause
each of their respective Subsidiaries to maintain with responsible insurance
companies insurance with respect to properties and business against casualties
and contingencies in at least the amounts customarily maintained, and against

pursuant to this Section shall name the Administrative Agent on behalf of the
Secured Parties as loss payee (in the case of property insurance) or additional

cancellation or modification of the policies will be made without thirty days'
prior written notice to the Administrative Agent.

     SECTION 7.1.5. BOOKS AND RECORDS; BORROWING BASE AUDITS.

     (a) The Parent and each Borrower will, and will cause each of their
respective Subsidiaries to, keep books and records in accordance with GAAP which
accurately reflect in all material respects all of its business affairs and
transactions and permit (i) each Agent and any of its respective
representatives, and (ii) at any time during which an Event of Default is
continuing, each Lender and any of its respective representatives, in each case
at reasonable times and intervals upon reasonable notice to each Borrower, to

its officers and employees, and its independent public accountants (and the
Parent and each Borrower hereby authorize such independent public accountant to
discuss each Obligor's financial matters with each Agent and each Lender or
their representatives whether or not any representative of such Obligor is
present, so long as the applicable Borrower has been afforded a reasonable
opportunity to be present) and to examine (and photocopy extracts from) any of
its books and records. The cost and expense of each such visit shall be borne by
the applicable Agent or Lender, except that each Agent may make one such visit
each Fiscal Year and the cost and expense thereof shall be borne by the
Borrowers.

     (b) Without limiting the generality of the foregoing, upon request of the
Administrative Agent (i) on or before each anniversary of the Closing Date, (ii)
on or before the 20th day immediately following the last day of any Fiscal
Quarter, if, the average of the Excess Availability in effect on the last day of
such Fiscal Quarter and each of the two fiscal months ended most recently prior
to the last day of such Fiscal Quarter is less than $15,000,000 or (iii) at any
time during which any Default or Event of Default has occurred and is
continuing, the Administrative Agent shall have the option to perform (solely
with its own personnel), at the Borrowers' expense (as provided in SECTION
11.3(d)), an audit of the accounts receivable, inventory, accounts payable and
cash accounts of the Borrowers and their respective Subsidiaries, in each case
in a

                                      -74-
<Page>

manner consistent with the Borrowing Base Audit delivered on or prior to the
Closing Date.

     (c) At the request of the Administrative Agent, in its sole discretion
(unless the PP&E Release Event shall have occurred, in which case no such
appraisal shall be required), the Borrowers shall permit the Administrative
Agent or one or more agents to perform, at the Borrowers' expense, an appraisal
of the inventory, property, plant and equipment of the Borrowers, in each case
in a manner consistent with the Asset Appraisal delivered on or prior to the
Closing Date; PROVIDED, HOWEVER, that (i) the Administrative Agent shall not be
entitled to perform more than one such appraisal in any calendar year and (ii)
the cost to the Borrowers of performing such appraisals shall not exceed
$100,000 per appraisal.

     SECTION 7.1.6. ENVIRONMENTAL LAW COVENANT. The Parent and the Borrowers
will, and will cause each of their respective Subsidiaries to, (i) use and
operate all of its and their facilities and properties in compliance with all
Environmental Laws, keep all necessary permits, approvals, certificates,

promptly notify the Administrative Agent and provide copies upon request of all
written notices of violations, claims or complaints relating to the condition of
its facilities and properties or its compliance with Environmental Laws which
relate to environmental matters that could reasonably be expected to have a
Material Adverse Effect, and shall promptly resolve any non-compliance with
Environmental Laws and (iii) provide such information and certifications which
the Agents may reasonably request from time to time to evidence compliance with
this SECTION 7.1.6. Nothing in this provision shall be construed to limit the
ability to contest in good faith any such notices of violations, written claims
or complaints.

     SECTION 7.1.7. USE OF PROCEEDS. The Borrowers will apply the proceeds of
the Credit Extensions as follows:

          (a) to consummate the Refinancing;

          (b) to pay fees and expenses incurred in connection with the
     Transactions; and

     Borrowers and the Subsidiary Guarantors, including (in the case of
     Loans other than Default Loans) Eligible Acquisitions by such Persons.

     SECTION 7.1.8. FUTURE SUBSIDIARIES. Upon any Person becoming, after the

of such Borrower or Subsidiary Guarantor, VHC shall notify the Agents of such
acquisition, and

                                      -75-

     promptly cause such Subsidiary to execute and deliver to the
     Administrative Agent, with counterparts for each Lender, a supplement
     to the Subsidiary Guaranty or, in the case of a wholly-owned U.S.
     Subsidiary a Joinder Agreement pursuant to SECTION 11.15 hereof,
     together in each case with a supplement to the Pledge and Security
     Agreement (and, if such Subsidiary owns any real property, to the
     extent required by CLAUSE (b) of SECTION 7.1.9 a Mortgage with respect
     to all such real property), together with Uniform Commercial Code
     financing statements (Form UCC-1) naming the Subsidiary as the debtor
     and the Administrative Agent as the secured party, or other similar
     instruments or documents, in appropriate form for filing under the
     Uniform Commercial Code and any other applicable recording statutes,
     in the case of real property, of all jurisdictions as may be necessary
     or, in the reasonable opinion of the Administrative Agent, desirable
     to perfect the security interest of the Administrative Agent pursuant
     to the Pledge and Security Agreement or a Mortgage, as the case may be
     (other than the perfection of security interests in motor vehicles,
     leasehold interests in real property (except to the extent required by
     SECTION 7.1.9) and non-U.S. intellectual property); and

          (b) such Borrower or Subsidiary Guarantor shall promptly deliver,
     or cause to be delivered, to the Administrative Agent under the Pledge
     and Security Agreement (or a supplement thereto) certificates (if any)
     representing all of the issued and outstanding shares of Capital Stock
     of such Subsidiary owned by such Borrower or such Subsidiary
     Guarantor, as the case may be, along with undated stock powers for
     such certificates, executed in blank, or, if any securities subject
     thereto are uncertificated securities or are held through a securities
     intermediary, confirmation and evidence satisfactory to the Agents
     that appropriate book entries have been made in the relevant books or
     records of a securities intermediary or the issuer of such securities,
     as the case may be, or other appropriate steps shall have been taken
     under applicable law resulting in the perfection of the security
     interest granted in favor of the Administrative Agent pursuant to the
     terms of the Pledge and Security Agreement;

together, in each case, with such opinions, in form and substance and from
counsel satisfactory to the Agents, as the Agents may reasonably require;
PROVIDED that not more than 65% of the Voting Securities of any Non-U.S.
Subsidiary shall be required to be pledged unless such Non-U.S. Subsidiary is
treated for U.S. federal income tax purposes as a branch of a Borrower or is a
partnership in which the partners are Borrowers.

     SECTION 7.1.9. FUTURE LEASED PROPERTY AND FUTURE ACQUISITIONS OF REAL
PROPERTY: FUTURE ACQUISITION OF OTHER PROPERTY. (a) Prior to entering into any
new lease of real property or renewing any existing lease of real property
following the Closing Date, each Borrower shall, and shall cause each of its
U.S. Subsidiaries to, use its (and their) best efforts (which shall not require
the expenditure of cash or the making of any material concessions under the
relevant lease) to deliver to the Administrative Agent a waiver executed by the
lessor of any real property that is to be leased by such Borrower or such U.S.
Subsidiary for a term in excess of one year in any state whose statutes grant
such lessor a "landlord's" (or similar) Lien which is superior to the
Administrative Agent's, to the extent the value of any personal property of any
Borrower or any

                                      -76-
<Page>

of its U.S. Subsidiaries to be held at such leased property exceeds (or it is
anticipated that the value of such personal property will, at any point in time
during the term of such leasehold term, exceed) $5,000,000.

     (b) In the event that any Borrower or any of their respective U.S.
Subsidiaries shall acquire any real property having a value as determined in
good faith by the Administrative Agent in excess of $1,000,000, such Borrower or
the applicable U.S. Subsidiary shall, promptly after such acquisition, execute a
Mortgage and provide the Administrative Agent with (i) evidence of the
completion (or satisfactory arrangements for the completion) of all recordings
and filings of such Mortgage as may be necessary or, in the reasonable opinion
of the Administrative Agent, desirable effectively to create a valid, perfected
first priority Lien, subject to Liens permitted by SECTION 7.2.3, against the
properties purported to be covered thereby, (ii) mortgagee's title insurance
policies in favor of the Agents and the Secured Parties in amounts and in form
and substance and issued by insurers, reasonably satisfactory to the Agents,
with respect to the property purported to be covered by such Mortgage, insuring
that title to such property is marketable and that the interests created by the
Mortgage constitute valid first Liens thereon free and clear of all defects and
encumbrances other than as approved by the Agents, and such policies shall, if
available on commercially reasonable terms, also include a revolving credit
endorsement and such other endorsements as the Agents shall request and shall be
accompanied by evidence of the payment in full of all premiums thereon, and
(iii) such other approvals, or documents as the Agents may reasonably request.

     (c) In accordance with the terms and provisions of the Loans Documents,
provide the Administrative Agent with evidence of all recordings and filings as

desirable to create a valid, perfected first priority Lien, subject to the Liens
permitted by SECTION 7.2.3, against all property acquired after the Closing Date
(excluding motor vehicles, leases of real property and non-U.S. intellectual
property).

     SECTION 7.1.10. COLLECTION OF ACCOUNTS. Each Borrower shall use
commercially reasonable efforts to cause to be collected from each Account
Debtor, as and when due, any and all amounts owing under or on account of each
Account (including, without limitation, Accounts which are delinquent, such
Accounts to be collected in accordance with lawful collection procedures) and
shall apply forthwith upon receipt thereof all such amounts as are so collected
to the outstanding balance of such Account, except that an Obligor may allow in
the ordinary course of business as adjustments to amounts owing under its
Accounts (i) an extension or renewal of the time or times of payment, or
settlement for less than the total unpaid balance, which such Obligor finds
appropriate in accordance with sound business judgment and (ii) a refund or
credit due as a result of discounts, over billings and miscellaneous credits,
all in accordance with such Obligor's ordinary course of business. The costs and
expenses (including, without limitation, attorneys' fees) of collection, whether
incurred by an Obligor or the Administrative Agent, shall be borne by such
Obligors.

     SECTION 7.1.11. NOTIFICATION TO ACCOUNT DEBTORS. Upon the request of the
Administrative Agent at any time following the occurrence of and during the
continuance of an Event of Default, each Borrower will promptly notify each
Account Debtor in respect of any Account that any payments due or to become due

be specified by the Administrative Agent. Each such payment shall, upon receipt
by the Administrative Agent, be deposited in the Concentration Account. Upon
request of the Administrative Agent at any time following the occurrence of and
during the continuance of an Event of Default, each Borrower shall promptly
notify (and each Borrower hereby authorizes the Administrative Agent so to
notify) each Account Debtor in respect of any Account that such Account has been
assigned to the Administrative Agent for the benefit of the Secured Parties and
that any payments due or to become due in respect of such Account are to be made
directly to the Administrative Agent in accordance with SECTION 3.1.1(d).

     arrangements for the completion) of all recordings and filings of each
     Mortgage as may be necessary or, in the reasonable opinion of the Lead
     Arranger, desirable to create a valid, perfected first priority Lien,
     subject to SECTION 7.2.3, against the properties purported to be
     covered thereby;

          (b) mortgagee's title insurance policies in favor of the
     Administrative Agent for the benefit of the Secured Parties in form
     and substance and issued by insurers, reasonably satisfactory to the
     Lead Arranger, with respect to the property set forth on SCHEDULE III
     in the amounts set forth thereon, insuring that title to such property
     is marketable and that the interests created by such Mortgage
     constitute valid first Liens thereon free and clear of all defects and

     required by the Lead Arranger and if available on commercially
     reasonable terms, revolving credit endorsement, comprehensive
     endorsement, variable rate endorsement, access and utilities
     endorsements, mechanic's lien endorsement and such other endorsements
     as the Lead Arranger shall reasonably request and shall be accompanied

case duly executed by the applicable Borrower and the applicable bank, as the
Administrative Agent deems necessary or desirable to grant to the Administrative
Agent, for the benefit of the Secured Parties, control over, and a perfected
security interest in, each of the Deposit Accounts listed on SCHEDULE VI hereto;

     percentage of the issued and outstanding interests of Capital
     Securities (on a fully diluted basis) of the surviving Person as the
     Administrative Agent had immediately prior to such merger or
     consolidation;

                            THE ADMINISTRATIVE AGENT

     SECTION 9.1. ACTIONS. Each Lender hereby appoints The CIT Group/Business
Credit, Inc. as its Administrative Agent under and for purposes of each Loan
Document. Each Lender authorizes the Administrative Agent to act on behalf of
such Lender under each Loan Document and, in the absence of other written
instructions from the Required Lenders received from time to time by the
Administrative Agent (with respect to which the Administrative Agent agrees that
it will comply, except as otherwise provided in this Section or as otherwise
advised by counsel in order to avoid contravention of applicable law), to
exercise such powers hereunder and thereunder as are specifically delegated to
or required of the Administrative Agent by the terms hereof and thereof,
together with such powers as may be incidental thereto. Each Lender hereby
indemnifies (which indemnity shall survive any termination of this Agreement)
the Administrative Agent, PRO RATA according to such Lender's proportionate
Total Exposure Amount, from and against any and all liabilities, obligations,
losses, damages, claims, costs or expenses of any kind or nature whatsoever
which may at any time be imposed on, incurred by, or asserted against, the
Administrative Agent in any way relating to or arising out of any Loan Document,
(including attorneys' fees and including any expenses, reimbursements and/or
indemnities paid by the Administrative Agent to any bank pursuant to any deposit
account control agreement relating to any Deposit Account), and as to which the
Administrative Agent is

                                      -94-
<Page>

not reimbursed by the Borrowers; PROVIDED, HOWEVER, that no Lender shall be
liable for the payment of any portion of such liabilities, obligations, losses,
damages, claims, costs or expenses which are determined by a court of competent
jurisdiction in a final proceeding to have resulted from the Administrative
Agent's gross negligence or willful misconduct. The Administrative Agent shall
not be required to take any action under any Loan Document, or to prosecute or
defend any suit in respect of any Loan Document, unless it is indemnified
hereunder to its satisfaction. If any indemnity in favor of the Administrative
Agent in respect of any indemnified act shall, in the Administrative Agent's
determination, be inadequate to compensate the Administrative Agent for all
indemnified losses resulting from such act or shall become impaired, the
Administrative Agent may call for additional indemnification from the Lenders
and cease to do the acts indemnified against hereunder until such additional
indemnity is given to its satisfaction.

     SECTION 9.2. FUNDING RELIANCE, ETC. Unless the Administrative Agent shall
have been notified by telephone, confirmed in writing by any Lender by 5:00
p.m., New York time, on the Business Day prior to a Borrowing that such Lender
will not make available the amount which would constitute its Percentage of such
Borrowing on the date specified therefor, the Administrative Agent may assume
that such Lender has made such amount available to the Administrative Agent and,
in reliance upon such assumption, make available to the applicable Borrowers a
corresponding amount. If and to the extent that such Lender shall not have made
such amount available to the Administrative Agent, such Lender and each Borrower
severally agree to repay the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
the Administrative Agent made such amount available to the applicable Borrower
to the date such amount is repaid to the Administrative Agent, at the interest
rate applicable at the time to Loans comprising such Borrowing (in the case of
the Borrowers) and (in the case of a Lender), at the Federal Funds Rate (for the
first two Business Days after which such amount has not been repaid), and
thereafter at the interest rate applicable to Loans comprising such Borrowing.

     SECTION 9.3. EXCULPATION. Neither the Administrative Agent nor any of its
directors, officers, employees or agents shall be liable to any Lender Party for
any action taken or omitted to be taken by it under any Loan Document, or in
connection therewith, except for its own willful misconduct or gross negligence,
nor responsible for any recitals or warranties herein or therein, nor for the
effectiveness, enforceability, validity or due execution of any Loan Document,
nor for the creation, perfection or priority of any Liens purported to be
created by any of the Loan Documents, or the validity, genuineness,
enforceability, existence, value or sufficiency of any collateral security, nor
to make any inquiry respecting the performance by any Obligor of its
Obligations. Any such inquiry which may be made by the Administrative Agent
shall not obligate it to make any further inquiry or to take any action. The
Administrative Agent shall be entitled to rely upon advice of counsel concerning
legal matters and upon any notice, consent, certificate, statement or writing
which the Administrative Agent believes to be genuine and to have been presented
by a proper Person.

     SECTION 9.4. SUCCESSOR. The Administrative Agent may resign as such at any
time upon at least 30 days' prior notice to the Borrowers and all Lenders. If
the Administrative Agent at any time shall resign, the Required Lenders may
appoint another Lender as a successor Administrative Agent which shall thereupon
become the Administrative Agent hereunder. If no

                                      -95-
<Page>

successor Administrative Agent shall have been so appointed by the Required
Lenders, and shall have accepted such appointment, within 30 days after the
retiring Administrative Agent's giving notice of resignation, then the retiring
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which shall be one of the Lenders or a commercial banking
institution organized under the laws of the United States (or any State thereof)
or a United States branch or agency of a commercial banking institution, and
having a combined capital and surplus of at least $500,000,000. Upon the
acceptance of any appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall be entitled to
receive from the retiring Administrative Agent such documents of transfer and
assignment as such successor Administrative Agent may reasonably request, and
shall thereupon succeed to and become vested with all rights, powers, privileges
and duties of the retiring Administrative Agent, and the retiring Administrative
Agent shall be discharged from its duties and obligations under the Loan
Documents. After any retiring Administrative Agent's resignation hereunder as
the Administrative 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 the
Administrative Agent under the Loan Documents, and SECTION 11.3 and SECTION 11.4
shall continue to inure to its benefit.

     SECTION 9.5. CREDIT EXTENSIONS BY EACH AGENT. Each Agent shall have the
same rights and powers with respect to (x) the Credit Extensions made by it or
any of its affiliates, and (y) the Notes held by it or any of its affiliates as
any other Lender and may exercise the same as if it were not an Agent. Each
Agent and its affiliates may accept deposits from, lend money to, and generally
engage in any kind of business with any Borrower or any Subsidiary or Affiliate
of any Borrower as if such Agent were not an Agent hereunder.

     SECTION 9.6. CREDIT DECISIONS. Each Lender acknowledges that it has,
independently of the Agents and each other Lender, and based on such Lender's
review of the financial information of VHC, the Loan Documents (the terms and
provisions of which being satisfactory to such Lender) and such other documents,
information and investigations as such Lender has deemed appropriate, made its
own credit decision to extend its Commitments. Each Lender also acknowledges
that it will, independently of the Agents and each other Lender, and based on
such other documents, information and investigations as it shall deem
appropriate at any time, continue to make its own credit decisions as to
exercising or not exercising from time to time any rights and privileges
available to it under the Loan Documents.

     SECTION 9.7. COPIES, ETC. The Administrative Agent shall give prompt notice
to each Lender of each notice or request required or permitted to be given to
the Administrative Agent by any Borrower pursuant to the terms of the Loan
Documents (unless concurrently delivered to the Lenders by such Borrower). The
Administrative Agent will distribute to each Lender each document or instrument
received for its account and copies of all other communications received by the
Administrative Agent from any Borrower for distribution to the Lenders by the
Administrative Agent in accordance with the terms of the Loan Documents.

     SECTION 9.8. RELIANCE BY ADMINISTRATIVE AGENT. The Administrative Agent
shall be entitled to rely upon any certification, notice or other communication
(including any thereof by telephone, telecopy, telegram or cable) believed by it
to be genuine and correct and to have been signed or sent by or on behalf of the
proper Person, and upon advice and statements of legal

                                      -96-
<Page>

counsel, independent accountants and other experts selected by the
Administrative Agent. As to any matters not expressly provided for by the Loan
Documents, the Administrative Agent shall in all cases be fully protected in
acting, or in refraining from acting, thereunder in accordance with instructions
given by the Required Lenders or all of the Lenders as is required in such
circumstance, and such instructions of such Lenders and any action taken or
failure to act pursuant thereto shall be binding on all Lender Parties. For
purposes of applying amounts in accordance with this Section, the Administrative
Agent shall be entitled to rely upon any Lender Party that has entered into a
Qualified Hedging Obligation with any Obligor for a determination (which such
Lender Party agrees to provide or cause to be provided upon request of the
Administrative Agent) of the outstanding Obligations owed to such Lender Party
under any Qualified Hedging Obligation. Unless it has actual knowledge evidenced
by way of written notice from any such Lender Party or any Borrower to the
contrary, the Administrative Agent, in acting in such capacity under the Loan
Documents, shall be entitled to assume that no Qualified Hedging Obligation or
Obligations in respect thereof are in existence or outstanding between any
Lender Party and any Obligor.

     SECTION 9.9. DEFAULTS. The Administrative Agent shall not be deemed to have
knowledge or notice of the occurrence of a Default unless the Administrative
Agent has sent to the Borrowers or received from a Lender or a Borrower a
written notice specifying such Default and stating that such notice is a "Notice
of Default". In the event that the Administrative Agent receives such a notice
of the occurrence of a Default, the Administrative Agent shall give prompt
notice thereof to the Lenders. The Administrative Agent shall (subject to
SECTION 11.1) take such action with respect to such Default as shall be directed
by the Required Lenders; PROVIDED, that unless and until the Administrative
Agent shall have received such directions, the Administrative Agent may (but
shall not be obligated to) take such action, or refrain from taking such action,
with respect to such Default as it shall deem advisable in the best interest of
the Lender Parties except to the extent that this Agreement expressly requires
that such action be taken, or not be taken, only with the consent or upon the
authorization of the Required Lenders or all Lenders.

     SECTION 9.10. LEAD ARRANGER. Notwithstanding anything else to the contrary
contained in this Agreement or any other Loan Document, the Lead Arranger, in
its capacity as such, shall have no duties or responsibilities under this
Agreement or any other Loan Document nor any fiduciary relationship with any
Lender, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or otherwise exist
against the Lead Arranger in such capacity except as are explicitly set forth
herein or in the other Loan Documents. The Lead Arranger shall at all times have
the right to receive a current copy of the Register and any other information
relating to the Lenders and the Loans that it may request from the
Administrative Agent.

     SECTION 9.11. THE SYNDICATION AGENT, THE DOCUMENTATION AGENT AND THE
ADMINISTRATIVE AGENT. Notwithstanding anything else to the contrary contained in
this Agreement or any other Loan Document, the Syndication Agent, the
Documentation Agent and the Administrative Agent, each in such capacity, shall
have no duties or responsibilities under this Agreement or any other Loan
Document nor any fiduciary relationship with any Lender, and no implied
covenants, functions, responsibilities, duties, obligations or liabilities shall
be read into this Agreement or otherwise exist against the Syndication Agent,
the Documentation Agent

                                      -97-

or Administrative Agent, as applicable, in such capacity, except as are
explicitly set forth herein or in the other Loan Documents.

                                    ARTICLE X
                                    GUARANTY

     SECTION 10.1. GUARANTY. The Parent and each Borrower (with respect to the
obligations of each other Borrower) hereby absolutely, unconditionally and
irrevocably:

          (a) guarantees the full and punctual payment when due, whether at
     stated maturity, by required prepayment, declaration, acceleration or
     otherwise, of all Obligations of the Borrowers now or hereafter
     existing, whether for principal, interest (including interest accruing
     at the then applicable rate provided in the Agreement after the
     occurrence of any Default set forth in SECTION 8.1.9, whether or not a
     claim for post-filing or post-petition interest is allowed under
     applicable law following the institution of a proceeding under
     bankruptcy, insolvency or similar laws), fees, Reimbursement
     Obligations, expenses or otherwise (including all such amounts which
     would become due but for the operation of the automatic stay under
     Section 362(a) of the United States Bankruptcy Code, 11 U.S.C. Section
     362(a), and the operation of Sections 502(b) and 506(b) of the United
     States Bankruptcy Code, 11 U.S.C. Section 502(b) and Section 506(b));
     and

          (b) indemnifies and holds harmless each Lender Party for any and
     all reasonable costs and expenses (including reasonable attorneys'
     fees and expenses) incurred by such Lender Party after the occurrence
     and during the continuance of an Event of Default in enforcing any
     rights under this Agreement;

Each Obligor's obligations under this Article constitute a guaranty of payment
when due and not of collection, and each Obligor specifically agrees that it
shall not be necessary or required that any Lender Party exercise any right,
assert any claim or demand or enforce any remedy whatsoever against any Obligor
or any other Person before or as a condition to the obligations of such Obligor
hereunder.

     SECTION 10.2. REINSTATEMENT, ETC. Each Obligor hereby agrees that its
obligations under this Article shall continue to be effective or be reinstated,
as the case may be, if at any time any payment (in whole or in part) of any of
the Obligations is invalidated, declared to be fraudulent or preferential, set
aside, rescinded or must otherwise be restored by any Lender Party, including
upon the occurrence of any Default set forth in SECTION 8.1.9 or otherwise, all
as though such payment had not been made.

     SECTION 10.3. GUARANTY ABSOLUTE, ETC. Each Obligor's obligations under this
Article shall in all respects be a continuing, absolute, unconditional and
irrevocable guaranty of payment, and shall, unless thereafter reinstated in
accordance with SECTION 10.2, remain in full force and effect until the
Termination Date. Each Obligor guarantees, to the fullest extent permitted under
applicable law, that the Obligations will be paid strictly in accordance with
the terms of each Loan Document under which they arise, regardless of any law,
regulation or order now or hereafter in effect in any jurisdiction affecting any
of such terms or the rights of any Lender Party with respect thereto. The
liability of each Obligor under this Article shall, to the

                                      -98-
<Page>

fullest extent permitted under applicable law, be absolute, unconditional and
irrevocable irrespective of:

          (a) any lack of validity, legality or enforceability of any Loan
     Document (other than this ARTICLE X);

          (b) the failure of any Lender Party:

               (i)  to assert any claim or demand or to enforce any right or
          remedy against any other Obligor or any other Person (including
          any other Guarantor) under the provisions of any Loan Document or
          otherwise, or

               (ii) to exercise any right or remedy against any other
          Guarantor of, or collateral securing, any Obligations;

          (c) any change in the time, manner or place of payment of, or in
     any other term of, all or any part of the Obligations, or any other
     extension, compromise or renewal of any Obligation;

          (d) any reduction, limitation, impairment or termination of any
     Obligations for any reason, including any claim of waiver, release,
     surrender, alteration or compromise, and shall not be subject to (and
     each Obligor hereby irrevocably waives, until payment of all
     Obligations, any right to or claim of) any defense or setoff,
     counterclaim, recoupment or termination whatsoever by reason of the
     invalidity, illegality, nongenuineness, irregularity, compromise,
     unenforceability of, or any other event or occurrence affecting, any
     Obligations or otherwise;

          (e) any amendment to, rescission, waiver, or other modification
     of, or any consent to or departure from, any of the terms of any Loan
     Document;

          (f) any addition, exchange or release of any collateral or of any
     Person that is (or will become) a Guarantor of the Obligations, or any
     surrender or non-perfection of any collateral, or any amendment to or
     waiver or release or addition to, or consent to or departure from, any
     other guaranty held by any Lender Party securing any of the
     Obligations; or

          (g) any other circumstance which might otherwise constitute a
     defense available to, or a legal or equitable discharge of, any
     Obligor, any surety or any Guarantor.

     SECTION 10.4. WAIVER, ETC. Except for any notices expressly required to be
delivered to an Obligor hereunder, each Obligor hereby waives promptness,
diligence, notice of acceptance and any other notice with respect to any of the
Obligations and the guaranty set forth in this ARTICLE X and any requirement
that any Lender Party protect, secure, perfect or insure any Lien, or any
property subject thereto, or exhaust any right or take any action against any
Obligor or any other Person (including the Parent) or entity or any collateral
securing the Obligations, as the case may be.

                                      -99-
<Page>

     SECTION 10.5. POSTPONEMENT OF SUBROGATION, ETC. Each Obligor agrees that it
will not exercise any rights which it may acquire by way of rights of
subrogation hereunder, nor shall such Obligor seek or be entitled to seek any
contribution or reimbursement from any Obligor, in respect of any payment made
hereunder, until following the Termination Date. Any other amount paid to any
Obligor on account of any such subrogation rights prior to the Termination Date
shall be held in trust for the benefit of the Lender Parties and shall
immediately be paid and turned over to the Administrative Agent for the benefit
of the Lender Parties in the exact form received by such Obligor (duly endorsed
in favor of the Administrative Agent, if required), to be credited and applied
against the Obligations, whether matured or unmatured, in accordance with
SECTION 4.7; PROVIDED that if the Obligors have made payment to the Lender
Parties of all or any part of the Obligations and the Termination Date has
occurred, then at an Obligor's request, the Administrative Agent (on behalf of
the Lender Parties) will, at the expense of the Parent, execute and deliver to
such Obligor appropriate documents (without recourse and without representation
or warranty) necessary to evidence the transfer by subrogation to such Obligor
of an interest in the Obligations resulting from such payment. In furtherance of
the foregoing, at all times prior to the Termination Date, such Obligor shall
refrain from taking any action or commencing any proceeding against any other
Obligor (or its successors or assigns, whether in connection with a bankruptcy
proceeding or otherwise) to recover any amounts in respect of payments made
hereunder to any Lender Party.

                                   ARTICLE XI
                            MISCELLANEOUS PROVISIONS

     SECTION 11.1. WAIVERS, AMENDMENTS, ETC. The provisions of each Loan
Document may from time to time be amended, modified or waived, if such
amendment, modification or waiver is in writing and consented to by each Obligor
party thereto and the Required Lenders; PROVIDED, HOWEVER, that no such
amendment, modification or waiver shall:

          (a) modify this Section or CLAUSE (a) of SECTION 11.10 without
     the consent of all Lenders;

          (b) increase the aggregate amount of any Credit Extensions
     required to be made by a Lender pursuant to its Commitments or extend
     the final Commitment Termination Date of Credit Extensions made (or
     participated in) by a Lender, in each case without the consent of such
     Lender (it being agreed, however, that any vote to rescind any
     acceleration made pursuant to SECTION 8.2 and SECTION 8.3 of amounts
     owing with respect to the Loans and other Obligations shall only
     require the vote of the Required Lenders);

          (c) reduce the principal amount of or rate of interest on any
     Lender's Loan, reduce any fees described in ARTICLE III payable to any
     Lender or extend the date on which interest or fees are payable in
     respect of such Lender's Loans, in each case without the consent of
     such Lender;

          (d) reduce the percentage set forth in the definition of
     "Required Lenders" or modify any requirement hereunder that any
     particular action be taken by all Lenders or Required Lenders without
     the consent of all Lenders;

                                      -100-
<Page>

          (e) increase the Stated Amount of any Letter of Credit unless
     consented to by the Issuer of such Letter of Credit;

          (f) (i) change the definition of "Borrowing Base Amount",
     "Eligible Account", "Eligible Inventory", "Eligible PP&E", "Maximum
     PP&E Advance Amount", "Orderly Liquidation Value" or "Net Asset Value"
     (in each case if the effect of such change would be to require a
     Lender to make or participate in a Credit Extension in an amount that
     is greater than such Lender would have had to make or participate in
     immediately prior to such change), (ii) amend, modify or waive SECTION
     3.1.1(b) or (iii) amend or waive any condition precedent to the making
     of a Revolving Loan or the issuance of a Letter of Credit without the
     consent of Lenders holding at least 75% of the Revolving Loan
     Commitments; or

          (g) except as otherwise expressly provided in a Loan Document,
     release (i) VHC from its financial Obligations under the Loan
     Documents or the Parent or all or substantially all of the Borrowers
     (other than VHC) and the Subsidiary Guarantors their respective
     financial Obligations under the Loan Documents (ii) all or
     substantially all of the collateral under the Loan Documents (other
     than in connection with the PP&E Release Event), in each case without
     the consent of all Lenders;

          (h) waive any Event of Default, or reverse the effects of any
     resulting acceleration of the Obligations, under CLAUSE (b), (c) or
     (d) of SECTION 8.1.9, unless consented to by all of the Lenders; or

          (i) affect adversely the interests, rights or obligations of the
     Administrative Agent (in its capacity as the Administrative Agent) or
     any Issuer (in its capacity as Issuer), unless consented to by the
     Administrative Agent or such Issuer, as the case may be.

No failure or delay on the part of any Lender Party in exercising any power or
right under any Loan Document shall operate as a waiver thereof, nor shall any
single or partial exercise of any such power or right preclude any other or
further exercise thereof or the exercise of any other power or right. No notice
to or demand on any Obligor in any case shall entitle it to any notice or demand
in similar or other circumstances. No waiver or approval by any Lender Party
under any Loan Document shall, except as may be otherwise stated in such waiver
or approval, be applicable to subsequent transactions. No waiver or approval
hereunder shall require any similar or dissimilar waiver or approval thereafter
to be granted hereunder.

     SECTION 11.2. NOTICES; TIME. All notices and other communications provided
under each Loan Document shall be in writing or by facsimile and addressed,
delivered or transmitted, if to a Borrower, the Parent, the Administrative
Agent, a Lender or an Issuer, to the applicable Person at its address or
facsimile number set forth on SCHEDULE II hereto or, in the case of a Lender
that becomes a party hereto after the date hereof, set forth in the Lender
Assignment Agreement pursuant to which it became a Lender, or at such other
address or facsimile number as may be designated by such party in a notice to
the other parties. Any notice, if mailed and properly addressed with postage
prepaid or if properly addressed and sent by pre-paid courier

                                      -101-

facsimile, shall be deemed given when the confirmation of transmission thereof
is received by the transmitter. The parties hereto agree that delivery of an
executed counterpart of a signature page to this Agreement and each other Loan
Document by facsimile shall be effective as delivery of an original executed
counterpart of this Agreement or such other Loan Document. Unless otherwise
indicated, all references to the time of a day in a Loan Document shall refer to
New York time.

     SECTION 11.3. PAYMENT OF COSTS AND EXPENSES. The Borrowers agree, jointly
and severally, to pay on demand all reasonable out-of-pocket fees, costs and
expenses of the Agents (including the reasonable fees and out-of-pocket expenses
of Mayer, Brown, Rowe & Maw, counsel to the Agents, and of local counsel, if
any, who may be retained by or on behalf of the Agents) in connection with:

          (a) the syndication by the Syndication Agent and the Lead
     Arranger of the Loans and Commitments, the negotiation, preparation,
     execution and delivery of each Loan Document, including schedules and

     modifications to any Loan Document as may from time to time hereafter
     be required, whether or not the transactions contemplated hereby are
     consummated; and

          (b) the filing or recording of any Loan Document (including the
     Filing Statements) and all amendments, supplements, amendments and
     restatements and other modifications to any thereof, searches made
     following the Closing Date in jurisdictions where Filing Statements
     (or other documents evidencing Liens in favor of the Lender Parties)
     have been recorded and any and all other documents or instruments of
     further assurance required to be filed or recorded by the terms of any
     Loan Document, in each case as necessary to create, maintain or
     continue perfection of the Liens purported to be granted pursuant to
     the Loan Documents;

          (c) the preparation and review of the form of any document or
     instrument relevant to any Loan Document; and

          (d) all costs and out-of-pocket expenses (including per diem
     rates of and out-of-pocket expenses incurred by employees or agents of
     the Administrative Agent in connection with any Borrowing Base Audit
     or Asset Appraisal performed by the Administrative Agent) incurred by
     the Agents in connection with any Asset Appraisal or Borrowing Base
     Audits; PROVIDED, HOWEVER, that the cost to the Borrowers of any Asset
     Appraisal shall not exceed $100,000 for each such appraisal.

The Borrowers further agree, jointly and severally, to pay, and to save each
Lender Party harmless from all liability for, any stamp and other similar which
may be payable in connection with the execution or delivery of each Loan
Document, the Credit Extensions or the issuance of the Notes. The Borrowers also
agrees, jointly and severally, to reimburse each Lender Party upon demand for
all reasonable out-of-pocket expenses (including reasonable attorneys' fees and
legal expenses of counsel to such Lender Party) incurred by such Lender Party
after the occurrence and during the continuance of an Event of Default in
connection with (x) the

                                      -102-

negotiation of any restructuring or "work-out" with any Borrower, whether or
not consummated, of any Obligations, (y) the enforcement of any Obligations and
(z) to the extent permitted under applicable law, the participation in or
monitoring of any bankruptcy or other reorganization or insolvency proceeding
relating to any Borrower or any of their respective Subsidiaries.

     SECTION 11.4. INDEMNIFICATION. In consideration of the execution and
delivery of this Agreement by each Lender Party, each of the Parent and each
Borrower, on a joint and several basis, to the fullest extent permitted under
applicable law, hereby indemnifies, exonerates and holds each Lender Party and
each of their respective officers, directors, employees and agents and each
other Person controlling any of the foregoing within the meaning of either
Section 15 of the Securities Act of 1933, as amended, or Section 20 of the
Securities Exchange Act of 1934, as amended (collectively, the "INDEMNIFIED
PARTIES") free and harmless from and against any and all actions, causes of
action, suits, losses, costs, liabilities and damages, and expenses
(irrespective of whether any such Indemnified Party is a party to the action for
which indemnification hereunder is sought), including reasonable attorneys' fees
and disbursements, whether incurred in connection with actions between or among
the parties hereto or the parties hereto and third parties (collectively, the
"INDEMNIFIED LIABILITIES"), in each case incurred by the Indemnified Parties or
any of them as a result of, or arising out of, or relating to

          (a) any transaction financed or to be financed in whole or in
     part, directly or indirectly, with the proceeds of any Credit
     Extension, including all Indemnified Liabilities arising in connection
     with the Transactions;

          (b) the entering into and performance of any Loan Document by any
     of the Indemnified Parties (excluding any successful action brought by
     or on behalf of any Borrower as the result of any failure by a Lender
     to make any Credit Extension required to be made by it hereunder);

          (c) with respect to any properties of the Obligors, any
     investigation, litigation or proceeding related to any environmental

     Environmental Law relating to the use, ownership or operation by any
     Obligor or any Subsidiary thereof of any Hazardous Material;

          (d) any investigation, litigation or proceeding related to any

     of any Person, whether or not each Agent, such Issuer, such Lead
     Arranger or such Lender is party thereto; or

          (e) the presence on or under, or the escape, seepage, leakage,
     spillage, discharge, emission or releases from, any real property
     owned or operated by any Obligor or any Subsidiary thereof of any
     Hazardous Material present on or under such property in a manner
     giving rise to liability during or prior to the time such Obligor or
     Subsidiary owned or operated such property (including any losses,
     liabilities, damages, injuries, costs, expenses or claims asserted or
     arising under any Environmental Law), regardless of whether caused by,
     or within the control of, such Obligor or Subsidiary;

                                      -103-
<Page>

except (i) for any such Indemnified Liabilities arising for the account of a
particular Indemnified Party by reason of the gross negligence or willful
misconduct of such Indemnified Party or (ii) any such Indemnified Liabilities
arising for the account of a particular Indemnified Party by reason of any
Hazardous Materials that are manufactured, emitted, generated, treated,
released, stored or disposed of on any real property of the Parent or any of its
Subsidiaries or any violation of Environmental Law that occurs on or with
respect to any real property of the Parent or any of its Subsidiaries to the
extent occurring after such real property is transferred to any Indemnified
Person or its successor by foreclosure sale, deed in lieu of foreclosure, or
similar transfer, except to the extent such manufacture, emission, release,
generation, treatment, storage or disposal or violation is actually caused by
the Parent or any of its Subsidiaries. Each of the Borrowers and the Parent and
their respective successors and assigns hereby waive, release and agree not to
make any claim or bring any cost recovery action against, any Indemnified Party
under CERCLA or any state equivalent, or any similar law now existing or
hereafter enacted, except to the extent arising out of the gross negligence or

such real property is transferred to any Indemnified Person or its successor by
foreclosure sale, deed in lieu of foreclosure, or similar transfer, except to
the extent such manufacture, emission, release, generation, treatment, storage
or disposal or violation is actually caused by the Parent, any Borrower or any
of their respective Subsidiaries. It is expressly understood and agreed that to
the extent that any Indemnified Party is strictly liable under any Environmental
Laws, the Borrowers' and the Parent's obligations to such Indemnified Party
under this indemnity shall, to the extent permitted under applicable law
likewise be without regard to fault on the part of any Obligor with respect to
the violation or condition which results in liability of an Indemnified Party.
Notwithstanding anything to the contrary herein, each Lender Party shall be
responsible with respect to any Hazardous Materials that are manufactured,
emitted, generated, treated, released, stored or disposed of on any real
property of any Borrower or any of their Subsidiaries or any violation of
Environmental Law that occurs on or with respect to any such real property to
the extent it occurs after such real property is transferred to any Indemnified
Party or its successor by foreclosure sale, deed in lieu of foreclosure, or
similar transfer, except to the extent such manufacture, emission, release,
generation, treatment, storage or disposal or violation is actually caused by
the Parent, any Borrower or any of their respective Subsidiaries. If and to the
extent that the foregoing undertaking may be unenforceable for any reason, each
of the Borrowers and the Parent agrees to make the maximum contribution to the
payment and satisfaction of each of the Indemnified Liabilities which is
permissible under applicable law.

     SECTION 11.5. SURVIVAL. The obligations of the Borrowers under SECTIONS
4.3, 4.4, 4.5, 4.6, 11.3 and 11.4, and the obligations of the Lenders under
SECTION 4.8 and SECTION 9.1, shall in each case survive any assignment from one
Lender to another (in the case of SECTIONS 11.3 and 11.4) and the occurrence of
the Termination Date. The representations and warranties made by any Obligor in
any Loan Document shall survive the execution and delivery of such Loan
Document.

     SECTION 11.6. SEVERABILITY. Any provision of any Loan Document which is
prohibited or unenforceable in any jurisdiction shall, as to such provision and
such jurisdiction, be

                                      -104-
<Page>

ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions of such Loan Document or affecting the
validity or enforceability of such provision in any other jurisdiction.

     SECTION 11.7. HEADINGS. The various headings of each Loan Document are
inserted for convenience only and shall not affect the meaning or
interpretation of such Loan Document or any provisions thereof.

     SECTION 11.8. EXECUTION IN COUNTERPARTS, EFFECTIVENESS, ETC. This Agreement
may be executed by the parties hereto in several counterparts, each of which
shall be an original and all of which shall constitute together but one and the
same agreement. This Agreement shall become effective when counterparts hereof
executed on behalf of the Parent, the Borrowers, the Administrative Agent and
each Lender (or notice thereof satisfactory to the Administrative Agent), shall
have been received by the Administrative Agent.

     SECTION 11.9. GOVERNING LAW; ENTIRE AGREEMENT. EACH LOAN DOCUMENT (OTHER
THAN THE LETTERS OF CREDIT, TO THE EXTENT SPECIFIED BELOW AND EXCEPT AS
OTHERWISE EXPRESSLY SET FORTH IN A LOAN DOCUMENT) WILL EACH BE DEEMED TO BE A
CONTRACT MADE UNDER AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW YORK
(INCLUDING FOR SUCH PURPOSE SECTIONS 5-1401 AND 5-1402 OF THE GENERAL
OBLIGATIONS LAW OF THE STATE OF NEW YORK). EACH LETTER OF CREDIT SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OR RULES DESIGNATED IN
SUCH LETTER OF CREDIT, OR IF NO LAWS OR RULES ARE DESIGNATED, THE INTERNATIONAL
STANDBY PRACTICES (ISP98--INTERNATIONAL CHAMBER OF COMMERCE PUBLICATION NUMBER
590 (THE "ISP RULES")) AND, AS TO MATTERS NOT GOVERNED BY THE ISP RULES, THE
INTERNAL LAWS OF THE STATE OF NEW YORK. The Loan Documents constitute the entire
understanding among the parties hereto with respect to the subject matter
thereof and supersede any prior agreements, written or oral, with respect
thereto.

     SECTION 11.10. SUCCESSORS AND ASSIGNS.

          (a) The provisions of this Agreement shall be binding upon and
     inure to the benefit of the parties hereto and their respective
     successors and assigns permitted hereby, except that neither the
     Parent nor any Borrower may assign or otherwise transfer any of its
     rights or obligations hereunder (other than, in the case of any
     Borrower that is a Subsidiary of VHC, pursuant to a merger,
     consolidation or liquidation permitted under SECTION 7.2.10) without
     the prior written consent of each Lender (and any attempted assignment
     or transfer by either the Parent or any Borrower without such consent
     shall be null and void). Nothing in this Agreement, expressed or
     implied, shall be construed to confer upon any Person (other than the
     parties hereto, their respective successors and assigns permitted
     hereby and, to the extent expressly contemplated hereby, the
     Indemnified Parties) any legal or equitable right, remedy or claim
     under or by reason of this Agreement.

                                      -105-
<Page>

          (b) Any Lender may assign to one or more Eligible Assignees
     pursuant to a Lender Assignment Agreement, all or any portion of its
     rights and obligations under this Agreement (including all or a
     portion of its Commitments and/or the Loans at the time owing to it);
     PROVIDED, HOWEVER, that (i) except in the case of an assignment of the
     entire remaining amount of the assigning Lender's Commitments and/or
     the Loans at the time owing to it or in the case of an assignment to a
     Lender or an affiliate of a Lender or an Approved Fund with respect to
     a Lender, the aggregate amount of the Commitments (which for this
     purpose includes Loans outstanding thereunder) and/or principal
     outstanding balance of the Loans of the assigning Lender subject to
     each such assignment (determined as of the date the Lender Assignment
     Agreement with respect to such assignment is delivered to the
     Administrative Agent) shall not be less than $5,000,000 unless each of
     the Administrative Agent and, so long as no Event of Default has
     occurred and is continuing, the Borrowers otherwise consent (each such
     consent not to be unreasonably withheld or delayed), (ii) each partial
     assignment shall be made as an assignment of a proportionate part of
     all the assigning Lender's rights and obligations under this Agreement
     with respect to the Loans and/or the Commitments assigned and (iii)
     the parties to each assignment shall execute and deliver to the
     Administrative Agent a Lender Assignment Agreement. The assignor
     Lender or the Assignee Lender must pay a processing fee in the amount
     of $3,000 to the Administrative Agent upon delivery of any Lender
     Assignment Agreement assigning any Revolving Loans and/or any
     Revolving Loan Commitments; PROVIDED, however that if assignments are
     made to or from an Approved Fund or any other Lender or affiliate of a
     Lender, such fee shall be waived. Subject to acceptance and recording
     thereof by the Administrative Agent pursuant to CLAUSE (c) of this
     Section, from and after the effective date specified in each
     Assignment and Acceptance, the Eligible Assignee thereunder shall be a
     party hereto and, to the extent of the interest assigned by such
     Lender Assignment Agreement, have the rights and obligations of a
     Lender under this Agreement, and the assigning Lender thereunder
     shall, to the extent of the interest assigned by such Lender
     Assignment Agreement, be released from its obligations under this
     Agreement (and, in the case of a Lender Assignment Agreement covering
     all of the assigning Lender's rights and obligations under this
     Agreement, such Lender shall cease to be a party hereto, but shall
     continue to be entitled to the benefits of any provisions of this
     Agreement which by their terms survive the termination of this
     Agreement). Any assignment or transfer by a Lender of rights or
     obligations under this Agreement that does not comply with this clause
     shall be treated for purposes of this Agreement as a sale by such
     Lender of a participation in such rights and obligations in accordance
     with CLAUSE (d).

          (c) The Administrative Agent shall record assignments made in
     accordance with this Section in the Register in accordance with CLAUSE
     (b) of SECTION 2.7.

          (d) In the event that S&P, Moody's or Thompson's BankWatch (or
     InsuranceWatch Ratings Service, in the case of Lenders that are
     insurance

                                      -106-
<Page>

     companies (or Best's Insurance Reports, if such insurance company is
     not rated by Insurance Watch Ratings Service)) shall, after the date
     that any Lender with a Commitment to make Revolving Loans or
     participate in Letters of Credit becomes a Lender, downgrade the
     long-term certificate of deposit rating or long-term senior unsecured
     debt rating of such Lender, and the resulting rating shall be below
     BBB-, Baa3 or C (or BB, in the case of Lender that is an insurance
     company (or B, in the case of an insurance company not rated by
     InsuranceWatch Ratings Service)) respectively, then the Issuer or the
     Borrowers (with the consent of the Agents and the Issuer) shall have
     the right, but not the obligation, upon notice to such Lender and the
     Agents, to replace such Lender with an Eligible Assignee in accordance
     with and subject to the restrictions contained in this Section, and
     such Lender hereby agrees to transfer and assign without recourse (in
     accordance with and subject to the restrictions contained in this
     Section) all its interests, rights and obligations in respect of its
     Revolving Loan Commitment under this Agreement to such Eligible
     Assignee; PROVIDED, HOWEVER, that (i) no such assignment shall
     conflict with any law, rule and regulation or order of any
     governmental authority and (ii) such Eligible Assignee shall pay to
     such Lender in immediately available funds on the date of such
     assignment the principal of and interest and fees (if any) accrued to
     the date of payment on the Loans made, and Letters of Credit
     participated in, by such Lender hereunder and all other amounts
     accrued for such Lender's account or owed to it hereunder.

          (e) Any Lender may, without the consent of, or notice to, any
     Borrower or the Administrative Agent, sell participations to one or
     more banks or other entities (a "PARTICIPANT") in all or a portion of
     such Lender's rights and/or obligations under this Agreement
     (including all or a portion of its Commitments and/or the Loans owing
     to it); PROVIDED, that (i) such Lender's obligations under this
     Agreement shall remain unchanged, (ii) such Lender shall remain solely
     responsible to the other parties hereto for the performance of such
     obligations and (iii) the Borrowers, the Administrative Agent and the
     other Lenders shall continue to deal solely and directly with such
     Lender in connection with such Lender's rights and obligations under
     this Agreement. Any agreement or instrument pursuant to which a Lender
     sells such a participation shall provide that such Lender shall retain
     the sole right to enforce this Agreement and to approve any amendment,
     modification or waiver of any provision of this Agreement; PROVIDED
     that any amendment, modification or waiver with respect to the
     following: (i) any reduction in the interest rate or amount of fees
     that such Participant is otherwise entitled to, (ii) a decrease in the
     principal amount of, or an extension of the final stated maturity date
     of, any Loan in which such Participant has purchased a participating
     interest, (iii) a release of all or substantially all of the
     collateral security under the Loan Documents or all or substantially
     all of the Borrowers that are Subsidiaries of VHC and the Subsidiary
     Guarantors from their Obligations, in each case except as otherwise
     specifically provided in a Loan Document or (iv) a change in the date
     fixed for payment of any interest or fees on any Loan in which such
     Participant has purchased a participating interest, may require the
     consent of the applicable Participant(s). The Borrowers acknowledge
     and agree that, to the fullest extent permitted under applicable law,
     each

                                      -107-
<Page>

     Participant, for purposes of SECTIONS 4.3, 4.4, 4.5, 4.6, 4.8, 4.9,
     7.1.1, 11.3 and 11.4, shall be considered a Lender. Each Participant
     shall only be indemnified for increased costs pursuant to SECTION 4.3,
     4.5 or 4.6 if and to the extent that the Lender which sold such
     participating interest to such Participant concurrently is entitled to
     make, and does make, a claim on any Borrower for such increased costs.
     Any Lender that sells a participating interest in any Loan, Commitment
     or other interest to a Participant under this Section shall indemnify
     and hold harmless the Borrowers and the Administrative Agent from and
     against any taxes, penalties, interest or other costs or losses
     (including reasonable attorneys' fees and expenses) incurred or
     payable by the Borrowers or the Administrative Agent as a result of
     the failure of the any Borrower or the Administrative Agent to comply
     with its obligations to deduct or withhold any taxes from any payments
     made pursuant to this Agreement to such Lender or the Administrative
     Agent, as the case may be, which taxes would not have been incurred or
     payable if such Participant had been a Non-U.S. Lender that was
     entitled to deliver to the Borrowers, the Administrative Agent or such
     Lender, and did in fact so deliver, a duly completed and valid Form
     W-8BEN or W-8ECI (or applicable successor form) entitling such
     Participant to receive payments under this Agreement without deduction
     or withholding of any United States federal taxes.

          (f) Any Lender may at any time pledge or assign a security
     interest in all or any portion of its rights under this Agreement (i)
     to secure obligations of such Lender, including any pledge or
     assignment to secure obligations to a Federal Reserve Bank or in
     support of its obligations to its trustee, as applicable and (ii) in
     connection with any securitization of any portfolio loans of such
     Lender, in each case without the prior written consent of any other
     Person; PROVIDED, that no such pledge or assignment of a security
     interest shall release a Lender from any of its obligations hereunder
     or substitute any such pledgee, trustee or assignee for such Lender as
     a party hereto.

          (g) Notwithstanding anything to the contrary contained herein,
     any Lender (a "GRANTING BANK") may grant to a special purpose funding
     vehicle (a "SPC"), identified as such in writing from time to time by
     the Granting Bank to the Administrative Agent and the Borrowers, the
     option to provide to any Borrower all or any part of any Loan that
     such Granting Bank would otherwise be obligated to make to any
     Borrower pursuant to this Agreement; PROVIDED that (i) nothing herein
     shall constitute a commitment by any SPC to make any Loan and (ii) if
     an SPC elects not to exercise such option or otherwise fails to
     provide all or any part of such Loan, the Granting Bank shall be
     obligated to make such Loan pursuant to the terms hereof. The making
     of an Loan by a SPC hereunder shall utilize the Commitment of the
     Granting Bank to the same extent, and as if, such Loan were made by
     such Granting Bank. Each party hereto hereby agrees that no SPC shall
     be liable for any indemnity or similar payment obligation under this
     Agreement (all liability for which shall remain with the Granting
     Bank). In furtherance of the foregoing, each party hereto hereby
     agrees (which agreement shall survive the termination of this
     Agreement) that, prior to the date that is one year and one day after
     the payment in full of all outstanding commercial paper or

                                      -108-
<Page>

     other senior indebtedness of any SPC, it will not institute against,
     or join any other person in instituting against, such SPC any
     bankruptcy, reorganization, arrangement, insolvency or liquidation
     proceedings under the laws of the United States or any State thereof.
     In addition, notwithstanding anything to the contrary contained in
     this Section, any SPC may (i) with notice to, but without the prior
     written consent of, the Borrowers or the Administrative Agent and
     without paying any processing fee therefor, assign all or a portion of
     its interests in any Loans to the Granting Bank or to any financial
     institutions (consented to by the Borrowers and Administrative Agent)
     providing liquidity and/or credit support to or for the account of
     such SPC to support the funding or maintenance of Loans and (ii)
     disclose on a confidential basis any non-public information relating
     to its Loans to any rating agency, commercial paper dealer or provider
     of any surety, guarantee or credit or liquidity enhancement to such
     SPC.

     SECTION 11.11. OTHER TRANSACTIONS. Nothing contained herein shall preclude
the Administrative Agent, any Issuer or any other Lender from engaging in any
transaction, in addition to those contemplated by the Loan Documents, with any
Borrower or any of their respective Affiliates in which such Borrower or such
Affiliate is not restricted hereby from engaging with any other Person.

     SECTION 11.12. FORUM SELECTION AND CONSENT TO JURISDICTION. ANY LITIGATION
BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, ANY LOAN
DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL
OR WRITTEN) OR ACTIONS OF THE ADMINISTRATIVE AGENT, THE LENDERS, ANY ISSUER, THE
PARENT OR ANY BORROWER IN CONNECTION HEREWITH OR THEREWITH MAY (TO THE EXTENT
PERMITTED UNDER APPLICABLE LAW) BE BROUGHT AND MAINTAINED IN THE COURTS OF THE
STATE OF NEW YORK LOCATED IN NEW YORK COUNTY OR IN THE UNITED STATES DISTRICT
COURT FOR THE SOUTHERN DISTRICT OF NEW YORK; PROVIDED, HOWEVER, THAT ANY SUIT
SEEKING ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT
THE ADMINISTRATIVE AGENT'S OPTION, IN THE COURTS OF ANY JURISDICTION WHERE SUCH
COLLATERAL OR OTHER PROPERTY MAY BE FOUND. THE BORROWERS AND THE PARENT
IRREVOCABLY CONSENT TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE
PREPAID, OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF NEW YORK AT THE
ADDRESS FOR NOTICES SPECIFIED IN SECTION 11.2. EACH BORROWER AND THE PARENT
HEREBY EXPRESSLY AND IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW,
ANY OBJECTION WHICH IT MAY HAVE OR HEREAFTER MAY HAVE TO THE LAYING OF VENUE OF
ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM
THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. TO THE
EXTENT THAT ANY BORROWER OR THE PARENT HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY
FROM JURISDICTION OF ANY COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH
SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION
OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, EACH BORROWER AND THE
PARENT HEREBY IRREVOCABLY

                                      -109-
<Page>

WAIVE TO THE FULLEST EXTENT PERMITTED BY LAW SUCH IMMUNITY IN RESPECT OF ITS
OBLIGATIONS UNDER THE LOAN DOCUMENTS.

     SECTION 11.13. WAIVER OF JURY TRIAL. THE ADMINISTRATIVE AGENT, EACH LENDER,
EACH ISSUER, THE PARENT AND EACH BORROWER HEREBY KNOWINGLY, VOLUNTARILY AND
INTENTIONALLY WAIVE TO THE FULLEST EXTENT PERMITTED BY LAW ANY RIGHTS THEY MAY
HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING
OUT OF, UNDER, OR IN CONNECTION WITH, ANY LOAN DOCUMENT, OR ANY COURSE OF
CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF
THE ADMINISTRATIVE AGENT, SUCH LENDER, SUCH ISSUER, THE PARENT OR SUCH BORROWER
IN CONNECTION THEREWITH. EACH BORROWER AND THE PARENT ACKNOWLEDGE AND AGREE THAT
THEY HAVE RECEIVED FULL AND SUFFICIENT CONSIDERATION FOR THIS PROVISION (AND
EACH OTHER PROVISION OF EACH OTHER LOAN DOCUMENT TO WHICH EACH IS A PARTY) AND
THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE ADMINISTRATIVE AGENT, EACH
LENDER AND EACH ISSUER ENTERING INTO THE LOAN DOCUMENTS.

     SECTION 11.14. CONFIDENTIALITY. The Lenders, the Issuers and the Agents
shall hold all non-public information obtained pursuant to or in connection with
this Agreement about, or obtained by them based on a review of the books and
records of, the Parent or any of its Subsidiaries in accordance with their
customary procedures for handling confidential information of this nature, but
may make disclosure to any of their examiners, affiliates, outside auditors,
counsel and other professional advisors or to any direct or indirect contractual
counterparty in swap agreements or such contractual counterparty's professional
advisor (so long as such contractual counterparty or professional advisor to
such contractual counterparty agrees to be bound by the provisions of this
Section) in connection with this Agreement or as reasonably required by any
potential BONA FIDE transferee, participant or assignee, or in connection with
the exercise of remedies under a Loan Document, or as requested by any
governmental agency or representative thereof or pursuant to legal process or to
any quasi-regulatory authority (including the National Association of Insurance
Commissioners); PROVIDED, HOWEVER, that

          (a) unless specifically prohibited by applicable law or court
     order, each Lender, each Issuer and each Agent shall notify VHC of any
     request by any governmental agency or representative thereof (other
     than any such request in connection with an examination of the
     financial condition of such Lender by such governmental agency) for
     disclosure of any such non-public information prior to disclosure of
     such information;

          (b) prior to any such disclosure pursuant to this Section, each
     Lender shall require any such BONA FIDE transferee, participant and
     assignee receiving a disclosure of non-public information to agree in
     writing (i) to be bound by this SECTION 11.14; and (ii) to require
     such Person to require any other Person to whom such Person discloses
     such non-public information to be similarly bound by this Section; and

                                      -110-
<Page>

          (c) except as may be required by an order of a court of competent
     jurisdiction and to the extent set forth therein, no Lender shall be
     obligated or required to return any materials furnished by the Parent
     or any of its Subsidiaries.

     SECTION 11.15. ADDITIONAL BORROWERS. Any wholly-owned U.S. Subsidiary of
VHC that is required to execute a Joinder Agreement pursuant to SECTION 7.1.8(a)
shall become a Borrower hereunder by executing and delivering to the
Administrative Agent a Joinder Agreement and a counterpart of this Agreement.
Upon delivery of such Joinder Agreement and related counterparts, such
Subsidiary shall automatically become a Borrower hereunder with the same force
and effect as if originally named as a Borrower hereunder. The execution and
delivery of any such Joinder Agreement or counterpart shall not require the
consent of any other Obligor or Lender Party hereunder. The rights and
obligations of each other Obligor hereunder shall remain in full force and
effect notwithstanding the addition of any new Borrower as a party to this
Agreement.

     SECTION 11.16. RELEASE OF CERTAIN BORROWERS. Upon any Borrower (other than
VHC) ceasing to be a Subsidiary of the Parent pursuant to a transaction
permitted under this Agreement, such Borrower shall be released from all of its
rights and obligations hereunder and under the Loan Documents and shall cease to
be Borrower for any purpose hereunder or thereunder; PROVIDED that such release
shall not affect the aggregate Obligations of the other Borrowers hereunder.

     SECTION 11.17. LIMITATION ON OBLIGATIONS OF CERTAIN BORROWERS. Anything in
this Agreement to the contrary notwithstanding, each Borrower shall only be
liable under this Agreement and the other Loan Documents for Loans borrowed by
it hereunder and for the maximum amount of other Obligations that it can incur
without rendering the agreements contained herein and in such other Loan
Documents, as they relate to such Borrower, voidable under applicable law
relating to fraudulent conveyance or fraudulent transfer, and not for any
greater amount.

March 26, 2002

Dear Peter:

          This letter agreement (this "Agreement") confirms our understanding
that Von Hoffmann Corporation (which, together with its subsidiaries and
affiliates is hereinafter referred to as the "Company" or "you") has engaged
Credit Suisse First Boston Corporation and its affiliates, successors and
assigns, as appropriate ("CSFB" or "we"), to act as its financial advisor for a
period of five (5) years (unless terminated earlier pursuant to Section 6 of
this Agreement) commencing upon the execution of this Agreement, with respect to
the matters set forth in the second paragraph of Section 1 below. Additionally,
CSFB has been engaged by the Company to provide the services set forth in the
third paragraph of Section 1 below (such engagements are collectively referred
to herein as the "Financial Advisory Assignment").

1.   APPOINTMENT AND ACCEPTANCE

     The Company hereby appoints CSFB as its financial advisor in connection
     with the Financial Advisory Assignment. CSFB hereby accepts such
     appointment, subject to the terms and conditions of this Agreement.

     In connection with the Financial Advisory Assignment, we propose to
     undertake certain services on your behalf, to the extent appropriate and
     requested by you, which shall consist of the following: (i) assisting you
     in analyzing the Company's operations and its historical performance; (ii)
     assisting you in analyzing the Company's future prospects; (iii) assisting
     you in preparing a strategic plan for the Company.

     Additionally, in connection with the Financial Advisory Assignment, we have
     been assisting the Company in evaluating its capital structure, analyzing
     financing strategies and developing an overall financing package, including
     a potential restructuring of its long-term debt, a new equity capital
     infusion and possible strategic alternatives.

     The Company acknowledges and agrees that CSFB has been retained solely to
     provide the advice or services set forth in this Agreement.

     CSFB's undertakings under this Agreement are subject to our continued
     satisfaction with the results of our ongoing review of the Company's
     business and affairs.

2.   FEES AND EXPENSES

     As compensation to CSFB for its services hereunder, the Company agrees to
     pay CSFB as follows:

     (a)  In connection with the Financial Advisory Assignment, (i) an annual
          financial advisory fee of $500,000, payable in equal quarterly
          installments beginning on the ninetieth day following the execution of
          this Agreement and continuing through the date of termination or
          expiration of this Agreement (if payable upon termination of this
          Agreement, such final installment to be paid on the effective

<Page>

          date of such termination and prorated for any final period consisting
          of less than ninety days) and (ii) an initial advisory fee of
          $1,000,000 in consideration of the recent financial advisory services
          that CSFB has provided to the Company in evaluating the Company's
          capital structure, analyzing financing strategies and developing an
          overall financing package, including a potential restructuring of its
          long-term debt, a new equity capital infusion and possible strategic
          alternatives; and

     (b)  Promptly upon request, the Company will reimburse CSFB's out-of-pocket
          expenses incurred in connection with its activities hereunder,
          including, without limitation, the fees and disbursements of its legal
          counsel, if any, and of any other advisor retained by CSFB (it being
          understood that the retention of any such advisor, other than legal
          counsel, will be made with the prior approval of the Company, which
          approval will not be unreasonably withheld), resulting from or arising
          out of this engagement.

          All fees and expenses payable hereunder are net of all applicable
          withholding and similar taxes.

3.   INFORMATION

     The Company will furnish CSFB with all financial and other information
     concerning the Company as CSFB deems appropriate in connection with the
     performance of the services contemplated by this engagement and, in that
     connection, will provide CSFB with reasonable access to the Company's
     officers, directors, employees, agents, accountants, counsel and other
     representatives. The Company acknowledges and confirms that CSFB (i) will
     rely solely on such information in the performance of the services
     contemplated by this engagement without assuming any responsibility for
     independent investigation or verification thereof, (ii) assumes no
     responsibility for the accuracy or completeness of such information or any
     other information regarding the Company and (iii) will not make any
     appraisal of any assets of the Company.

4.   INDEMNIFICATION

     Since CSFB will be acting on behalf of the Company in connection with its
     engagement hereunder and as further consideration for CSFB's services
     hereunder, the Company and CSFB agree to the indemnity provisions and other
     matters set forth in Annex A hereto which Annex A is incorporated herein by
     reference. The terms and provisions of Annex A shall survive any
     termination or expiration of this Agreement.

5.   ADDITIONAL SERVICES

     If, at any time during the term of this Agreement or prior to the date
     which is five (5) years from the date hereof (whichever is later), the
     Company is considering a Transaction (as defined herein) and CSFB is chosen
     by the Company to advise with respect to such Transaction, then CSFB will
     be paid, as compensation for such services, customary fees to be mutually
     agreed upon by the parties hereto at the appropriate time. The terms of any
     such additional engagement will be set forth in a separate letter agreement
     containing terms and conditions to be mutually agreed upon by the parties
     hereto, including, without limitation, appropriate indemnification
     provisions.

     As used herein, the term Transaction shall mean (i) the sale, merger,
     consolidation or other business combination, in one or more transactions,
     involving any portion of the business, securities or assets of the Company;
     (ii) the acquisition (and any related

                                        2
<Page>

     matters such as financings, divestitures, etc.), in one or more
     transactions, of all or a portion of the business, securities or assets of
     another entity or person; (iii) any recapitalization, refinancing,
     repurchase or restructuring of the Company's equity or debt securities or
     indebtedness or any amendments or modifications to the Company's debt
     securities or indentures whether or not in connection therewith, involving,
     by or on behalf of the Company, an offer to purchase or exchange for cash,
     property, securities, indebtedness or other consideration, or a
     solicitation of consents, waivers or authorizations with respect thereto;
     (iv) any spin-off, split-off or other extraordinary dividend of cash,
     securities or other assets to stockholders of the Company; or (v) any sale
     of securities of the Company effected pursuant to a private sale or an
     underwritten public offering.

     The Company further understands that if CSFB is asked to act for the
     Company in any other formal additional capacity not specifically addressed
     in this Agreement, such activities shall constitute separate engagements
     and the terms of any such additional engagements will be embodied in one or
     more separate written agreements containing terms and conditions to be
     mutually agreed upon by the parties hereto, including, without limitation,
     appropriate indemnification provisions. The indemnity provisions in Annex A
     hereto shall apply to any such other activities (unless superseded by an
     indemnity provision set forth in a separate agreement applicable to any
     such additional engagements) and shall remain in full force and effect
     regardless of any completion, modification or termination of CSFB's
     engagement(s).

6.   TERMINATION

     This Agreement may be terminated by CSFB or the Company at any time upon
     written notice to the other party. Upon any termination or expiration of
     this Agreement, CSFB will be entitled to prompt payment of all fees accrued
     prior to such termination or expiration and reimbursement of all
     out-of-pocket expenses as described above. No termination of CSFB's
     engagement hereunder shall affect (i) the Company's obligations under Annex
     A hereto or (ii) the provisions of Sections 4 through 7 of this Agreement.

7.   CONFIDENTIALITY; GENERAL

     No advice rendered by CSFB, whether formal or informal, may be disclosed,
     in whole or in part, or summarized, excerpted from or otherwise referred to
     without CSFB's prior written consent. To the extent consistent with legal
     requirements, all information given to one party of this Agreement (such
     party the "Recipient Party") by the other party (the "Providing Party"),
     including, without limitation, this Agreement, unless publicly available or
     otherwise available to the Recipient Party without restriction or breach of
     any confidentiality agreement, will be held by the Recipient Party in
     confidence and will not, without the Providing Party's prior approval, be
     disclosed to anyone other than the Recipient's agents and advisors who
     require such information to perform services for the Providing Party as
     contemplated by this Agreement (and who agree to use such information only
     in connection with such services) or used by such person for any purpose
     other than those contemplated by this Agreement. Each party hereto shall be
     responsible for violations of its respective agents and advisors of the
     obligations set forth in this paragraph.

     This Agreement and Annex A hereto contain the entire agreement of the
     parties with respect to the subject matter hereof and supersede and take
     precedence over all prior agreements or understandings, whether oral or
     written, between CSFB and the Company including, without limitation, the
     Letter Agreement, dated May 22, 1997 (the "DLJSC Letter Agreement"),
     between the Company and Donaldson, Lufkin & Jenrette Securities

                                        3

     Corporation ("DLJSC"), which DLJSC Letter Agreement is hereby terminated by
     DLJSC in accordance with its terms. The Company has all requisite power and
     authority to enter into this Agreement and the transactions contemplated
     hereby. This Agreement has been duly and validly authorized by all
     necessary action on the part of the Company and has been duly executed and
     delivered by the Company and constitutes a legal, valid and binding
     agreement of the Company, enforceable in accordance with its terms.

     In connection with this engagement, CSFB is acting as an independent
     contractor and not in any other capacity, with duties owing solely to the
     Company.

     The validity and interpretation of this Agreement shall be governed by, and
     construed and enforced in accordance with, the laws of the State of New
     York applicable to agreements made and to be fully performed therein
     (excluding the conflicts of law rules). All actions and proceedings arising
     out of or relating to this Agreement shall be heard and determined
     exclusively in any New York state or federal court sitting in the Borough
     of Manhattan in the City of New York, to whose jurisdiction the Company
     hereby irrevocably submits. The Company hereby irrevocably waives any
     defense or objection to the New York forum designated above. Each of CSFB
     and the Company, to the extent permitted by law, on behalf of their
     respective equity holders and creditors, hereby knowingly, voluntarily and
     irrevocably waives all right to trial by jury in any action, suit,
     proceeding or counterclaim (whether based upon contract, tort or otherwise)
     related to or arising out of the engagement of CSFB pursuant to, or the
     performance by CSFB of the services contemplated by, this agreement.

     The benefits of this Agreement shall inure to the parties hereto, their
     respective successors and assigns, and to the indemnified parties hereunder
     and their respective successors and assigns and representatives, and the
     obligations and liabilities assumed in this Agreement by the parties hereto

     itself, prevent CSFB from engaging in future transactions involving
     companies in a similar industry to the Company, provided the Company's
     confidential information is not used in connection with such engagement.

     The invalidity or unenforceability of any provision of this Agreement shall
     not affect the validity or enforceability of any other provisions of this
     Agreement or Annex A hereto, which shall remain in full force and effect.

                                     ANNEX A

          In further consideration of the engagement by Von Hoffmann Corporation
(the "Company") of Credit Suisse First Boston Corporation ("CSFB") to act in the
capacities set forth in our engagement letter dated the date hereof (the
"engagement"), in the event that CSFB or any of its affiliates, the respective
directors, officers, partners, agents or employees of CSFB or any of its
affiliates, or any other person controlling CSFB or any of its affiliates
(collectively, "Indemnified Persons") becomes involved in any capacity in any
action, claim, suit, investigation or proceeding, actual or threatened, brought
by or against any person, including stockholders of the Company, in connection
with or as a result of the engagement or any matter referred to in the
engagement, the Company will reimburse such Indemnified Person for its
reasonable and customary legal and other expenses (including, without
limitation, the costs and expenses incurred in connection with investigating,
preparing for and responding to third party subpoenas or enforcing this
agreement or any related engagement agreement) incurred in connection therewith
as such expenses are incurred. The Company will also indemnify and hold harmless
any Indemnified Person from and against, and the Company agrees that no
Indemnified Person shall have any liability to the Company or its owners,
parents, affiliates, security holders or creditors for, any losses, claims,
damages or liabilities (including actions or proceedings in respect thereof)
(collectively, "Losses") related to or arising out of the engagement or CSFB's
performance thereof, except that this section shall not apply to any Losses that
are finally determined by a court or arbitral tribunal to have resulted
primarily from the bad faith or gross negligence of CSFB.

          If such indemnification is for any reason not available or
insufficient to hold an Indemnified Person harmless, the Company agrees to
contribute to the Losses involved in such proportion as is appropriate to
reflect the relative benefits received (or anticipated to be received) by the
Company, on the one hand, and by CSFB, on the other hand, with respect to the
engagement or, if such allocation is determined by a court or arbitral tribunal
to be unavailable, in such proportion as is appropriate to reflect other
equitable considerations such as the relative fault of the Company, on the one
hand, and of CSFB, on the other hand; PROVIDED, HOWEVER, that, to the extent
permitted by applicable law, the Indemnified Persons shall not be responsible
for amounts which in the aggregate are in excess of the amount of all fees
actually received by CSFB from the Company in connection with the engagement.
Relative benefits to the Company, on the one hand, and to CSFB, on the other
hand, with respect to the engagement shall be deemed to be in the same
proportion as (i) the total value received or proposed to be received by the
Company in connection with the transactions contemplated by this Agreement,
whether or not consummated, bears to (ii) all fees actually received by CSFB in
connection with the engagement. Relative fault shall be determined, in the case
of Losses arising out of or based on any untrue statement or any alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact, by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company to CSFB and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statement or omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act of 1933, as amended) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

          The Company will not, without CSFB's prior written consent, settle,
compromise, or consent to the entry of any judgment in or otherwise seek to
terminate any pending or threatened action claim, suit, investigation or
proceeding (an "Action") in respect of which indemnification may be sought
hereunder (whether or not any Indemnified Person is a party therein) unless the
Company has given CSFB reasonable prior written notice thereof and such
settlement, compromise, consent or termination includes an unconditional release
of each Indemnified Person from any liabilities arising out of such Action. The
Company will not permit any such settlement, compromise, consent or termination

CSFB in writing thereof and, if requested by CSFB, shall arrange in connection
therewith alternative means of providing for the obligations of the Company set

insurance, surety bonds or the creation of an escrow, in each case in an amount
and on terms and conditions satisfactory to CSFB.

          The Company's obligations hereunder shall be in addition to any rights

respective appellate courts thereof. Notwithstanding the foregoing, solely for
the purpose of enforcing the Company's obligations hereunder, the Company

Indemnified Person. CSFB HEREBY AGREES, AND THE COMPANY HEREBY AGREES ON ITS OWN

restriction herein is held by a court of competent jurisdiction to be invalid,
void or unenforceable or against public policy, the remainder of the terms,
provisions and restrictions contained herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated.
