                                   ARTICLE II

                      ISSUANCES AND TRANSFERS OF SECURITIES

2.1  ISSUANCES AND TRANSFERS OF SECURITIES.

     The Company shall not, without the prior written consent of the Requisite
Investor Holders, issue or sell, or otherwise permit or record the Transfer of,
any Stockholder Share to any Person (other than pursuant to a Public Sale)
unless such Person is already a party to this Agreement or first executes and
delivers to the Company a joinder agreement in substantially the form attached
hereto as EXHIBIT A (a "JOINDER AGREEMENT"), pursuant to which such Person will
thereupon become a party to, and be bound by and obligated to comply with the
terms and provisions of, this Agreement.

2.2  CERTAIN TRANSFERS.

          (a) The provisions regarding Transfers of Securities contained in this
ARTICLE II shall apply to all Stockholder Shares now owned or hereafter acquired
by a Stockholder, including Stockholder Shares acquired by reason of original
issuance, dividend, distribution, exchange, conversion and acquisition of
outstanding Stockholder Shares from another Person, and such provisions shall
apply to any Stockholder Shares obtained by a Stockholder upon the exercise,
exchange or conversion of any option, warrant or other derivative Security.

          (b) Except for Transfers that constitute Public Sales, no Stockholder
shall Transfer any Stockholder Shares to a Person not already a party to this
Agreement as a Stockholder unless and until (i) such Person executes and
delivers to the Company a Joinder Agreement, pursuant to which such Person will
thereupon become a party to, and be bound by and obligated to comply with the
terms and provisions of, this Agreement, as a Stockholder hereunder, and (ii)
such Transfer is a Permitted Transfer or is made in compliance with this ARTICLE
II and, in any case, is made in compliance with ARTICLE V. No Person who
acquires Stockholder Shares in a Public Sale shall be required to execute a
Joinder Agreement.

2.3  CO-SALE RIGHTS.

          (a) After satisfying the obligations set forth in SECTION 2.4 and, in
the case of MQ Holdings, SECTION 2.7, if at any time any Stockholder proposes to
Transfer, other than pursuant to a Permitted Transfer (PROVIDED, HOWEVER, that a
Transfer pursuant to clause (b)(iii) of such definition shall not be deemed a
Permitted Transfer for purposes of this SECTION 2.3), any Stockholder Shares (in
each case, such Stockholder shall be deemed a "TRANSFERRING STOCKHOLDER"), then
at least thirty (30) days prior to the closing of such Transfer, such
Transferring Stockholder shall deliver a written notice (the "SALE NOTICE") to
all holders of Stockholder Shares (other than such Transferring Stockholder and
the Investor Stockholders) (the "OTHER STOCKHOLDERS") offering such Other
Stockholders the option to participate in such proposed Transfer upon the same
terms and conditions as such Transferring Stockholder. Such Sale Notice shall
specify in reasonable detail the identity of the prospective Transferee and the
terms and conditions of the Transfer, including the number and class of
Stockholder Shares to be Transferred.

                                       -9-
<Page>

          (b) Any Other Stockholder may, within twenty (20) days of the receipt
of a Sale Notice, give written notice (each, a "TAG-ALONG NOTICE") to such
Transferring Stockholder stating that such Other Stockholder wishes to
participate in such proposed Transfer and specifying the amount and class of
Stockholder Shares such Other Stockholder desires to include in such proposed
Transfer; PROVIDED, HOWEVER, that, if the Sale Notice relates to shares of
Common Stock, such Transferring Stockholder shall, if requested in such
Tag-Along Notice, use all reasonable efforts to cause the proposed Transferee to
agree to acquire warrants held by the Other Stockholder delivering such
Tag-Along Notice without the prior exercise thereof; PROVIDED FURTHER, HOWEVER,
that the consideration received upon such Transfer by such Other Stockholder
will be net of any exercise price of such warrants.

          (c) If no Other Stockholder gives such Transferring Stockholder a
timely Tag-Along Notice with respect to the Transfer proposed in the Sale
Notice, such Transferring Stockholder may thereafter Transfer the Stockholder
Shares specified in the Sale Notice on terms and conditions no more favorable to
such Transferring Stockholder than those set forth in the Sale Notice. If one or
more Other Stockholders give such Transferring Stockholder a timely Tag-Along
Notice, then such Transferring Stockholder shall use all reasonable best efforts
to cause the prospective Transferee(s) to agree to acquire all Stockholder
Shares identified in all Tag-Along Notices that are timely given to such
Transferring Stockholder, upon the same terms and conditions as applicable to
such Transferring Stockholder's Stockholder Shares. If the prospective
Transferee(s) are unwilling or unable to acquire all Stockholder Shares proposed
to be included in such sale upon such terms, then such Transferring Stockholder
may elect either to cancel such proposed Transfer or the maximum number of
Stockholder Shares that each prospective Transferee is willing to purchase shall
be allocated among such Transferring Stockholder and the Other Stockholders
giving timely Tag-Along Notices in proportion to each such Stockholders'
Proportionate Percentage.

          (d) Within ten (10) days after the date by which the Other
Stockholders were first required to notify the Transferring Stockholder of their
intent to participate, the Transferring Stockholder shall notify each Other
Stockholder who delivered a timely Tag-Along Notice of the number of Stockholder
Shares held by such Other Stockholder that will be included in the sale and the
day on which the sale is intended to be consummated, which shall be no later
than the later of (i) ninety (90) days after the date which the Other
Stockholders were required to notify the Transferring Stockholder of their
intent to participate and (ii) the date of satisfaction of any governmental
approval or filing requirements, if any.

2.4  RIGHT OF FIRST REFUSAL.

          (a) Except to the extent otherwise expressly permitted herein, no
Stockholder (other than an Investor Stockholder) shall Transfer, other than
pursuant to a Permitted Transfer, any Stockholder Shares except in compliance
with the procedures set forth in this SECTION 2.4 (and the other applicable
provisions of this Agreement).

          (b) If any Stockholder (other than an Investor Stockholder) shall
receive a BONA FIDE written offer (an "OFFER") from any Person (a "PROPOSED
TRANSFEREE") to purchase all or a portion of the Stockholder Shares then owned
by such Stockholder and such Stockholder desires to accept such Offer, such
Stockholder (the "OFFEROR") shall, before accepting such Offer, first

                                      -10-
<Page>

deliver to the Company and each of the Stockholders (other than the Offeror)
(collectively with the Company, the "OFFEREES") a written notice (the "NOTICE OF
OFFER"), which shall include all relevant terms of such Offer and shall be
irrevocable for a period of thirty (30) days after delivery thereof (the "OFFER
PERIOD"), offering (the "FIRST REFUSAL OFFER") all of the Stockholder Shares
proposed to be Transferred by the Offeror at the purchase price and on the terms
specified in the Offer, FIRST to the Company, or its designees, and SECOND to
such other Stockholders. The Offeror shall also furnish to the Offerees such
additional information in the Offeror's possession relating to the Offer as the
Offerees may reasonably request. The Company, or its designees, shall have the
first right and option, for a period of ten (10) days after delivery of the
Notice of Offer by the Offeror, to accept all or any portion of the Stockholder
Shares so offered at the purchase price and on the terms stated in the Notice of
Offer. The Company shall make such acceptance by delivering written notice
thereof to the Offeror and the other Offerees within such 10-day period. The
Company shall, if it does not elect to purchase all of the offered Stockholder
Shares, promptly upon such election (but in any event within such 10-day period)
deliver written notice thereof to the Offeror and the other Offerees. Each other
Stockholder shall then have the right and option, for a period of twenty (20)
days after the expiration of the 10-day period provided above, (x) to accept in
writing all or any of his or its Proportionate Percentage of the Stockholders
Shares so offered and not accepted by the Company at the purchase price and on
the terms stated in the Notice of Offer and (y) to offer, in any written notice
of acceptance, to purchase any Stockholder Shares not accepted by the other
Stockholders pursuant to this sentence, in which case the Stockholder Shares not
accepted by the other Stockholders shall be deemed, on the same terms and
conditions, to be re-offered from time to time during such 20-day period to and
accepted by the other Stockholders who exercised their option under this clause
(y), PRO RATA in accordance with their respective Proportionate Percentages
(computed without including the Stockholders who have not exercised their option
to purchase Stockholder Shares under this clause (y)), until all such
Stockholder Shares are fully subscribed or until all such other Stockholders
have subscribed for all such offered Stockholder Shares which they desire to
purchase.

          (c) Transfers of Stockholder Shares under the terms of this
SECTION 2.4 shall be made at the offices of the Company on a mutually
satisfactory Business Day within fifteen (15) days after the later of (i)
expiration of the Offer Period and (ii) the satisfaction of any governmental
approval or filing requirements, if any. Delivery of certificates or other
instruments evidencing such Stockholder Shares, duly endorsed for transfer and
free and clear of all liens, claims and other encumbrances, shall be made on
such date against payment of the purchase price therefor.

          (d) If the Offerees shall not have accepted all of the Stockholder
Shares offered for sale pursuant to the Notice of Offer, then the Offeror may
Transfer to the Proposed Transferee that number of the Stockholder Shares not
accepted by the Offerees in accordance with the terms set forth in the Notice of
Offer, at any time within ninety (90) days after the expiration of the First
Refusal Offer required by SECTION 2.4(a). Any such Transfer shall be in
compliance with SECTION 2.2 and SECTION 2.3. In the event the Stockholder Shares
are not Transferred by the Offeror to the Proposed Transferee on such terms
during such 90-day period, the restrictions of this SECTION 2.4 shall again
become applicable to any Transfer of Stockholder Shares by the Offeror.

2.5  REQUIRED SALE IN CONNECTION WITH A SALE OF THE COMPANY.

          (a) GENERAL. Subject to the further provisions of this SECTION 2.5, if
the Board and the Requisite Holders approve a Sale of the Company (an "APPROVED
SALE"), each Stockholder shall consent to and raise no objections against the
Approved Sale, and if the Approved Sale is structured as a sale of the issued
and outstanding capital stock of the Company (whether by merger,
recapitalization, consolidation or sale or Transfer of Stockholder Shares, other
Securities or otherwise), then each Stockholder shall waive any dissenters
rights, appraisal rights or similar rights in connection with such Sale of the
Company and each Stockholder shall agree to sell his or its Stockholder Shares
on the terms and conditions approved by the Board. Each Stockholder shall take
all necessary and desirable actions in connection with the consummation of the
Approved Sale, including the execution of such agreements and instruments and
other actions necessary to provide the representations, warranties, indemnities,
covenants, conditions, escrow agreement and other provisions and agreements
relating to such Approved Sale. Each Stockholder hereby grants an irrevocable
power of attorney and proxy to the Chairman of the Board of the Company to take
all necessary actions and execute and deliver all documents deemed by such
Person to be necessary or desirable to effectuate the terms of this SECTION 2.5,
such power of attorney and proxy only to be exercisable in the event that such
Stockholder fails for any reason to take any of the foregoing actions after
reasonable notice thereof. The restrictions on Transfers of Stockholder Shares
set forth in SECTIONS 2.1, 2.2, 2.3 and 2.4 shall not apply in connection with
an Approved Sale. Notwithstanding anything to the contrary contained herein, a
Sale of the Company that is not approved by all of the Investor Directors shall
not be deemed to be an "Approved Sale."

          (b) PROCEDURE. The Company shall deliver written notice to each
Stockholder setting forth in reasonable detail the terms (including price, time
and form of payment) of any Approved Sale (the "DRAG NOTICE"). Within ten (10)
days following receipt of the Drag Notice, each Stockholder shall deliver to the
Company written notice (in form and substance reasonably satisfactory to the
Company) setting forth such holders' agreement to consent to and raise no
objections against, or impediments to, the Approved Sale (including, waiving all
dissenter's and similar rights) and (ii) if the Approved Sale is structured as a
sale of stock, to sell its Stockholder Shares on the terms and conditions set
forth in the Drag Notice.

          (c) CONDITIONS TO OBLIGATION. The obligations of the Stockholders to
participate in any Approved Sale pursuant to this SECTION 2.5 are subject to the
satisfaction of the following conditions:

               (i)   subject to SECTION 2.5(c)(iii), upon the consummation of
     the Approved Sale (or as promptly thereafter as practical in the case of
     certain options to purchase Stock, pursuant to outstanding option
     agreements), all of the Stockholders shall receive the same proportion of
     the aggregate consideration from such Approved Sale that such holder would
     have received if such aggregate consideration had been distributed by the
     Company in complete liquidation pursuant to the rights and preferences set
     forth in the Restated Certificate as in effect immediately prior to such
     Approved Sale (giving effect to applicable orders of priority and the
     exercise price of all warrants and options);

                                      -12-
<Page>

              (ii)   if any Stockholders are given an option as to the form and
     amount of consideration to be received with respect to shares in a class,
     all holders of shares of such class will be given the same option;

             (iii)   all holders of then-currently exercisable or convertible
     Common Stock Equivalents will be given an opportunity to either (A)
     exercise or convert such rights prior to the consummation of an Approved
     Sale (but only to the extent such Common Stock Equivalents are then vested
     or would be vested on an accelerated basis upon such sale pursuant to the
     terms thereof) and participate in such sale as Stockholders or (B) upon the
     consummation of the Approved Sale, receive in exchange for such currently
     exercisable or convertible Common Stock Equivalents consideration equal to
     the product of (x) the same amount of consideration per Stockholder Share
     (of the same class as that for which the Common Stock Equivalent is
     exercisable or convertible) received by the holders of such class of
     capital stock in connection with the Approved Sale (less the exercise or
     conversion price per Common Stock Equivalent) and (y) the number of Common
     Stock Equivalents (but only to the extent such Common Stock Equivalents are
     then vested or would vest upon an accelerated basis upon such sale pursuant
     to the terms thereof);

              (iv)   no Stockholder shall be obligated to pay more than his or
     its PRO RATA share (based upon the number of Common Stock Equivalents held
     by such Stockholder) of reasonable expenses incurred in connection with a
     consummated Approved Sale to the extent such expenses are incurred for the
     benefit of all Stockholders and are not otherwise paid by the Company or
     the acquiring party (expenses incurred by or on behalf of a Stockholder for
     its or his sole benefit not being considered expenses incurred for the
     benefit of all Stockholders); and

               (v)   in the event that the Stockholders are required to provide
     any representations, warranties or indemnities in connection with an
     Approved Sale (other than representations, warranties and indemnities on a
     several basis concerning each Stockholder's valid ownership of his or its
     Stockholder Shares, free of all liens and encumbrances, enforceability and
     each Stockholder's authority, power, and right to enter into and consummate
     agreements relating to such Approved Sale without violating applicable law,
     its organizational documents or any other agreement to which it is a
     party), then each Stockholder shall not be liable for more than his or its
     PRO RATA share (based upon the number of Common Stock Equivalents held by
     such Stockholder) of any liability for misrepresentation or indemnity
     (except in respect of such several representations and warranties) and such
     liability shall not exceed the total purchase price received by such
     Stockholder (net of broker fees) from such purchaser for such Stockholder's
     Stockholder Shares and/or Common Stock Equivalents (including the exercise
     price thereof), and, to the extent that an indemnification, purchase price
     adjustment, or similar escrow has been established, such liability shall be
     satisfied solely out of any funds escrowed for such purposes prior to
     recourse against such Stockholder.

          (d) CONSULTATION WITH MANAGEMENT STOCKHOLDERS. Prior to the Company or
the Requisite Holders, as applicable, executing a binding commitment for any
Approved Sale (a "COMMITMENT"), the Investor Stockholders shall consult with the
Requisite Management Holders

                                      -13-
<Page>

regarding the terms and conditions of such Approved Sale at least thirty (30)
days prior to executing a Commitment. In addition, in the event of an Approved
Sale whereby the form of consideration includes securities, the Investor
Stockholders will use their reasonable, good faith efforts to structure such
Approved Sale in a manner so that the Management Stockholders will receive
securities having the same relative economic interest and rights as the
Stockholder Shares held by such Management Stockholders immediately before the
consummation of such Approved Sale; PROVIDED, HOWEVER, that the Investor
Stockholders shall not have any obligation hereunder if such structure would
result in less consideration or a greater detrimental economic effect to the
Investor Stockholders than would otherwise be the case immediately prior to the
consummation of any Approved Sale.

2.6  REPURCHASE RIGHT OF THE COMPANY.

          (a) If a Management Stockholder's employment with the Company is
terminated for any reason or for no reason, the Company or its designee shall
have the right (but not the obligation), upon delivery of a Repurchase Notice to
such Management Stockholder, to repurchase from such Management Stockholder (and
each of his Permitted Transferees) all or any part of the Stockholder Shares
owned by such Management Stockholder (and each of his Permitted Transferees) at
any time. The price per Stockholder Share to be paid by the Company shall be (i)
in the event of a termination of such Management Stockholder's employment with
the Company or any Subsidiary due to his death or disability or by the Company
or such Subsidiary without Cause, the Fair Market Value as of the last day of
the calendar month ending on, or immediately before, the date the Management
Stockholders' employment with the Company is so terminated or (ii) in the event
of a termination of such Management Stockholders' employment with the Company or
any Subsidiary by the Company or such Subsidiary with Cause or upon the
Management Stockholder's resignation, the lesser of the Original Cost and the
Fair Market Value thereof as of the date of such termination. For purposes of
this SECTION 2.6 only, the "Original Cost" of any share of the Company's Series
B Preferred Stock, $0.001 par value per share, shall include that amount equal
to the product of (X) the Original Cost of one share of Common Stock and (Y) the
Participation Component Shares (as such term is defined in the Restated
Certificate). The purchase price to be paid by the Company for any repurchase of
Stockholder Shares pursuant to this SECTION 2.6 shall be paid in cash; PROVIDED,
HOWEVER, that, if the Management Stockholder is terminated by the Company or
such Subsidiary with Cause or resigns, the Company shall have the option to pay
the purchase price as follows:

               (i)   33.333% of the purchase price in cash; PROVIDED FURTHER,
     HOWEVER, that the Company shall not be obligated to pay more than that
     which is permitted under the Credit Agreement, in which case such portion
     that is not permitted to be paid in cash shall be payable as provided in
     paragraph (ii) below; PROVIDED FURTHER, that the permitted amount referred
     to in the immediately preceding provision shall be reduced by an amount
     equal to the sum of all amounts paid or payable within the fiscal year in
     which such purchase is consummated in satisfaction of obligations owing
     pursuant to any notes issued, or to be issued in connection with the
     subject purchase of Stockholder Shares, pursuant to clause (ii) below; and

              (ii)  the remaining portion of the purchase price in the form of a
     non-negotiable promissory note payable to the order of the Management
     Stockholder, which

                                      -14-
<Page>

     note shall be (A) dated the date of the closing of such sale, bearing
     interest at the prime rate reported by J.P. Morgan Chase Bank, N.A. in the
     Wall Street Journal as of such closing date, (B) payable in three equal
     annual installments of principal and interest accrued thereon payable on an
     anniversary of the date of the note; PROVIDED, HOWEVER, that the aggregate
     amount required to be paid from time to time by the Company with respect to
     all of the outstanding notes issued pursuant to this SECTION 2.6(a)(ii)
     shall not exceed the amounts then permitted by the Credit Agreement or any
     covenant under any other financing document of the Company or its
     Subsidiaries (or any successor facility or facilities which contains
     restrictions on the payment of such notes which are not more restrictive
     than those currently contained in the Credit Agreement or such other
     document), and if such Credit Agreement or such other document does not
     permit the payment of all amounts payable in a fiscal year with respect to
     such notes, the amount permitted to be paid shall be allocated among such
     notes PRO RATA based upon the outstanding principal balances of such notes,
     (C) prepayable at any time without premium, such prepayments to be applied
     to payments of principal and then interest next due and (D) subordinated to
     any funded indebtedness of the Company and its Subsidiaries.

          (b) The purchasers of any Stockholder Shares pursuant to this
SECTION 2.6 will be entitled to require all of the sellers of Stockholder Shares
to provide representations and warranties from such seller regarding (i) such
seller's power, authority and legal capacity to enter into such sale and to
transfer valid right, title and interest in such Stockholder Shares, (ii) such
seller's ownership of such Stockholder Shares and the absence of any liens,
pledges, and other encumbrances on such Stockholder Shares and (iii) the absence
of any violation, default, or acceleration of any agreement or instrument
pursuant to which such seller or the assets of such seller are bound as the
result of such sale.

          (c) If the Company or any of its designees elect to exercise the
repurchase rights pursuant to this SECTION 2.6 and any seller fails to promptly
deliver all of such Stockholder Shares in accordance with the terms hereof, then
the purchaser of such Stockholder Shares hereunder may, at its option, in
addition to all other remedies it may have, deposit the purchase price in an
escrow account administered by an independent third party (to be held for the
benefit of and payment over to such seller in accordance herewith), whereupon
the Company shall by written notice to such seller (i) cancel on the Company's
books the certificate(s) representing such Stockholder Shares registered in the
name of such seller and (ii) issue to the purchaser, in lieu thereof, new
certificate(s) representing such Stockholder Shares registered in the
purchaser's name, and all of the seller's right, title, and interest in and to
such Stockholder Shares shall terminate in all respects without any action on
the part of such seller.

          (d) Anything contained in this Agreement to the contrary
notwithstanding, all repurchases of Stockholder Shares by the Company or its
designees pursuant to this SECTION 2.6 shall be subject to applicable
restrictions contained in federal law, the law of any other applicable
jurisdiction and in the Company's debt and equity financing agreements,
including the Credit Agreement. Anything contained in this Agreement to the
contrary notwithstanding, if any such restrictions prohibit or otherwise delay
the repurchase of Stockholder Shares or any payment of money in connection
therewith pursuant to this SECTION 2.6 which the Company is otherwise entitled
or required to make, the Company or its designees may make such repurchases or
such

                                      -15-
<Page>

payments as soon as it is permitted to do so under such restrictions. The
restrictions on Transfers of Stockholder Shares set forth in SECTIONS 2.3, 2.4
and 2.7 shall not apply in connection with any Transfer in connection with this
SECTION 2.6.

          (e) If Stockholder Shares are repurchased pursuant to this
SECTION 2.6, then the sellers and the purchasers thereof and their respective
successors, assigns and representatives shall take all steps necessary or
desirable to obtain, at their sole cost and expense, all required third-party,
governmental and regulatory consents and approvals (including any actions
required under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended) and shall take all other actions necessary or desirable to facilitate
consummation of such repurchase in a timely manner.

2.7  RIGHT OF FIRST OFFER.

          (a) If MQ Holdings desires to Transfer any Stockholder Shares held by
it (other than pursuant to a Permitted Transfer; PROVIDED, HOWEVER, that a
Transfer pursuant to clause (b)(iii) of such definition shall not be deemed a
Permitted Transfer for purposes of this SECTION 2.7), MQ Holdings shall:

               (i)   provide notice to the Management Stockholders in writing of
     its intent to Transfer such Stockholder Shares (the "ROFO TRANSFER NOTICE")
     and shall include in such ROFO Transfer Notice, the number and class of
     Stockholder Shares that MQ Holdings intends to Transfer;

              (ii)   upon receipt of a ROFO Transfer Notice, the Management
     Stockholders shall have ten (10) Business Days from the date of receipt of
     the ROFO Transfer Notice to inform MQ Holdings whether they desire to
     purchase such Stockholder Shares;

             (iii)   in the event that the Management Stockholders inform MQ
     Holdings in writing that they do not intend to purchase such Stockholder
     Shares or provide no response prior to the expiration of such ten (10)
     Business Days (the "MANAGEMENT STOCKHOLDERS' REJECTION"), MQ Holdings shall
     be entitled to Transfer such Stockholder Shares, free and clear of the
     restrictions set forth in this SECTION 2.7, but subject to SECTION 2.3, to
     any Person for any consideration for ninety (90) Business Days from the
     effective time of such Management Stockholders' Rejection (the "UNLIMITED
     TRANSFER PERIOD"). To the extent that MQ Holdings has not Transferred such
     Stockholder Shares within the Unlimited Transfer Period, MQ Holdings shall
     again comply with the provisions of this SECTION 2.7 prior to Transferring
     such Stockholder Shares that were not so Transferred; PROVIDED, HOWEVER, if
     such ROFO Transfer Notice was given in connection with, or in contemplation
     of, an Approved Sale, this last sentence of this clause (iii) shall be
     inapplicable and MQ Holdings shall be entitled to Transfer such Stockholder
     Shares without regard to this SECTION 2.7 for a period of three hundred and
     sixty-five (365) days following a Management Stockholders' Rejection
     (PROVIDED, that MQ Holdings shall be deemed to have satisfied the
     requirements of this proviso to this clause (iii) if MQ Holdings has
     entered into definitive documentation or is otherwise engaged in good faith
     negotiations in connection with such Transfer within such 365-day

                                      -16-
<Page>

     period notwithstanding that the actual Transfer of such Stockholder Shares
     occurs after the expiration of such period);

              (iv)   in the event that the Management Stockholders inform MQ
     Holdings in writing that they intend to purchase such Stockholder Shares
     (the "MANAGEMENT STOCKHOLDERS' OFFER"), the Management Stockholders shall
     indicate to MQ Holdings the per share price, in cash, they are willing to
     pay for such Stockholder Shares (the "MANAGEMENT STOCKHOLDERS AMOUNT") and
     evidence satisfactory to MQ Holdings of the source of financings of such
     purchase price and such Management Stockholders' Offer shall be irrevocable
     for ten (10) Business Days;

               (v)   if MQ Holdings accepts the Management Stockholders' Offer,
     the Management Stockholders and MQ Holdings shall complete the Transfer of
     such Stockholders' Shares within five (5) Business Days after the later of
     (A) thirty (30) Business Days from the date of delivery of such acceptance

     for a period of ninety (90) Business Days from the date of delivery of such
     rejection by MQ Holdings to the Management Stockholders (the "LIMITED
     TRANSFER PERIOD"), MQ Holdings shall be able to Transfer such Stockholder
     Shares, free and clear of the restrictions set forth in this SECTION 2.7,
     but subject to SECTION 2.3, to any other Person for a per share price that
     is not less than the Management Stockholders' Amount; PROVIDED, HOWEVER,
     that if such Transfer is in connection with an Approved Sale, such Limited
     Transfer Period shall be 180 Business Days. To the extent that MQ Holdings
     has not Transferred all of such Stockholder Shares within the Limited
     Transfer Period, MQ Holdings shall again comply with the provisions of this
     SECTION 2.7 prior to Transferring the Stockholder Shares that were not so
     Transferred.

     the Company's industry and shall not be an employee of the Company or any
     of its Subsidiaries; and

              (iv)   two (2) representatives designated by the Principal
     Management Holders for so long as the aggregate Percentage Ownership of the

     initially be Gene Venesky and J. Kenneth Luke; PROVIDED, HOWEVER, that at
     such time as the aggregate Percentage Ownership of the Principal Management
     Holders is reduced below ten percent (10%), (A) the Principal Management
     Holders shall have the right to designate two (2) representatives to the
     Board pursuant to this paragraph (iv) for so long as both Gene Venesky and

SECTION 3.1(a)(iv), prior to the Requisite Investor Holders designating the
Person whom the Requisite Investor Holders intend to fill any vacancy created by
the removal, resignation or death of any member elected to the Board pursuant to
SECTION 3.1(a)(i), the Requisite Investor Holders shall consult

                                      -18-

of any such designee and shall use their reasonable, good faith efforts to
designate a Person acceptable to the Requisite Management Holders; PROVIDED,
HOWEVER, that the Requisite Investor Holders shall not have any obligation
hereunder to designate any Person acceptable to the Requisite Management
Holders. The Company and the holders of Stockholder Shares shall use their best
efforts to fill any vacancies of the Board as soon as practicable following the
date such vacancy is created. Notwithstanding anything to the contrary contained
in this Agreement, in the event that the Requisite Management Holders shall no
longer have the right to designate members to the Board pursuant to

remove any such directors so designated and appointed.

business requested by the Company. So long as any Director serves on the Board

and exculpation of the Directors to the fullest extent permitted under
applicable law.

     Each Stockholder shall use all reasonable efforts to cause each Director
designated by such Stockholder to vote for the election to the Board of all
individuals designated in accordance with SECTION 3.1.

3.3  OBSERVATION RIGHTS.

          (a) Notwithstanding the provisions of SECTION 3.1, MQ Holdings shall
be entitled to designate one Person to serve as an observer (the "OBSERVER") at
all meetings of the Board.

          (b) The Company shall give the Observer reasonable prior notice (it
being agreed that the same prior notice given to the Directors shall be deemed
reasonable prior notice) in any manner permitted in the Company's By-laws for

furnished to any Director in connection with such meeting. The Observer will be

          (b) COVENANT NOT TO AMEND. The Company and each Stockholder agree not
to amend or waive the voting or other provisions of the Restated Certificate,
the By-laws or this Agreement if such amendment or waiver would cause MQ

                       SECURITIES LAW COMPLIANCE; LEGENDS

5.1  RESTRICTION ON TRANSFER.

     In addition to any other restrictions on the Transfer of any Stockholder
Shares contained in this Agreement, the Stockholders shall not Transfer any
Restricted Securities except in compliance with the conditions specified in this
ARTICLE V.

5.2  RESTRICTIVE LEGENDS.

     Each certificate for the Restricted Securities shall (unless otherwise
provided by the provisions of SECTION 5.4) be stamped or otherwise imprinted
with a legend in substantially the following terms:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
     INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES
     SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES OR BLUE
     SKY LAWS. THESE SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN THE
     ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT
     OR LAWS."

5.3  NOTICE OF TRANSFER.

     The holder of any Restricted Securities, by his or its acceptance or
purchase thereof, agrees, prior to any Transfer of any such Restricted
Securities (except pursuant to an effective Registration Statement), to give
written notice to the Company of such holder's intention to effect such Transfer
and agrees to comply in all other respects with the provisions of this ARTICLE V
and ARTICLE II. Each such notice shall describe the manner and circumstances of
the proposed Transfer and, unless waived by the Company, shall be accompanied by
the written opinion, addressed to the Company, of counsel for the holder of such
Restricted Securities (which counsel shall be reasonably satisfactory to the
Company), stating that in the opinion of such counsel (which opinion shall be
reasonably satisfactory to the Company) such proposed Transfer does not involve
a transaction requiring registration of such Restricted Securities under the
Securities Act; PROVIDED, HOWEVER, that no such opinion of counsel shall be
required in connection with any such Transfer to an Affiliate of such holder or
to an "accredited investor" (as such term is defined in Rule 501 promulgated
under the Securities Act) upon receipt by the Company of reasonably satisfactory
evidence of such transferee's status as such. Subject to complying with the
other applicable provisions hereof, such holder of Restricted Securities shall
be entitled to consummate such Transfer in accordance with the terms of the
notice delivered by him or it to the Company if

                                      -22-
<Page>

the Company does not reasonably object (on the basis that such Transfer violates
the provisions of this ARTICLE V) to such Transfer within five (5) days after
the delivery of such notice. Each certificate or other instrument evidencing the
Restricted Securities issued upon the Transfer of any Restricted Securities (and
each certificate or other instrument evidencing any untransferred balance of
such Restricted Securities) shall bear the legend set forth in SECTION 5.2)
unless (i) in such opinion of such counsel registration of future transfer is
not required by the applicable provisions of the Securities Act or (ii) the
Company shall have waived the requirement of such legend.

5.4  REMOVAL OF LEGENDS, ETC.

     Notwithstanding the foregoing provisions of this ARTICLE V, the
restrictions imposed by SECTIONS 5.1, 5.2 and 5.3 upon the transferability of
any Restricted Securities shall cease and terminate when (a) such Restricted
Securities are sold or otherwise disposed of in accordance with the intended
method of disposition by the seller or sellers thereof set forth in a
Registration Statement or are sold or otherwise disposed of in a transaction
contemplated by SECTION 5.3 which does not require that the Restricted
Securities transferred bear the legend set forth in SECTION 5.2, or (b) the
holder of such Restricted Securities has met the requirement of Transfer of such
Restricted Securities pursuant to subparagraph (k) of Rule 144. Whenever the
restrictions imposed by SECTIONS 5.1, 5.2 and 5.3 shall terminate, as herein
provided, the holder of any Restricted Securities shall be entitled to receive
from the Company, without expense, a new certificate not bearing the restrictive
legend set forth in SECTION 5.2 and not containing any other reference to the
restrictions imposed by SECTIONS 5.1, 5.2 and 5.3.

5.5  ADDITIONAL LEGEND.

          (a) Each certificate evidencing Stockholder Shares and each
certificate issued in exchange for or upon the Transfer of any Stockholder
Shares (if such shares remain Stockholder Shares as defined herein after such
Transfer) shall be stamped or otherwise imprinted with a legend in substantially
the following form:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A
     STOCKHOLDERS' AGREEMENT DATED AS OF AUGUST [_], 2002 (AS THE SAME MAY
     FROM TIME TO TIME BE AMENDED, RESTATED, SUPPLEMENTED OR OTHERWISE
     MODIFIED IN ACCORDANCE WITH THE TERMS THEREOF, THE "AGREEMENT"), AMONG
     THE ISSUER OF SUCH SECURITIES (THE "COMPANY") AND CERTAIN OF THE
     COMPANY'S Stockholders. THE TERMS OF THE AGREEMENT INCLUDE, AMONG
     OTHER THINGS, RESTRICTIONS ON TRANSFERS. A COPY OF THE AGREEMENT WILL
     BE FURNISHED WITHOUT CHARGE BY THE COMPANY TO THE HOLDER HEREOF UPON
     WRITTEN REQUEST."

          (b) The Company shall imprint such legends on certificates evidencing
shares outstanding prior to the date hereof. The legend set forth above shall be
removed from the certificates evidencing any shares which cease to be
Stockholder Shares in accordance with the terms of this Agreement.

                              AMENDMENT AND WAIVER

6.1  AMENDMENT.

     Except as expressly set forth herein, the provisions of this Agreement may
only be amended, modified or waived with the prior written consent of (a) the
Company and (b) the Requisite Holders; PROVIDED, HOWEVER, that (i) any such
amendment, modification, or waiver that would adversely affect the rights
hereunder of any Stockholder, in its capacity as a Stockholder of a particular
class (i.e., Investor Stockholders and Management Stockholders), without
similarly affecting the rights hereunder of all Stockholders of the same class,
in their capacities as Stockholders of such class, shall not be effective as to
such Stockholder without his or its prior written consent, (ii) any such
amendment, modification or waiver that would adversely affect the rights
hereunder of any particular class of Stockholders, in their capacities as
members of such class, without similarly affecting the rights hereunder of all
other classes of Stockholders, shall not be effective as to such class of
Stockholders without the prior written consent of the Stockholders of such class
holding in the aggregate in excess of fifty percent (50%) of the Stockholder
Shares held by such Stockholders as members of such class, (iii) any such
amendment, modification, or waiver that would adversely affect the rights
hereunder of JPMP Global Investors shall not be effective without its prior
written consent, and (iv) SCHEDULE I to this Agreement shall be deemed to be
automatically amended from time to time to reflect Transfers of Securities made
in compliance with ARTICLE II and ARTICLE V without requiring the consent of any
party, and the Company will, from time to time, distribute to the Stockholders a
revised SCHEDULE I to reflect any such changes.

6.2  WAIVER.

     No course of dealing between the Company and the Stockholders (or any of
them) or any delay in exercising any rights hereunder will operate as a waiver
of any rights of any party to this Agreement. The failure of any party to
enforce any of the provisions of this Agreement will in no way be construed as a
waiver of such provisions and will not affect the right of such party thereafter
to enforce each and every provision of this Agreement in accordance with its
terms

                                   ARTICLE VII

                                   TERMINATION

     The provisions of this Agreement, except as otherwise expressly provided
herein, shall terminate upon the first to occur of (a) the twentieth anniversary
of the date hereof, (b) the dissolution, liquidation or winding-up of the
Company, (c) the Sale of the Company, (d) the consummation of a Qualified Public
Offering or (e) the approval of such termination by (i) the Company, (ii) the
Requisite Holders and (iii) the Requisite Management Stockholders. Anything
contained herein to the contrary notwithstanding, as to any particular
Stockholder, this Agreement shall no longer be binding or of further force or
effect as to such Stockholder, except as otherwise expressly provided herein, as
of the date such Stockholder has Transferred all of

                                      -24-
<Page>

such Stockholder's interest in the Stockholder Shares and the Transferees of
such Stockholder Shares have, if required by SECTION 2.2(b) hereof, executed
Joinder Agreements.

                                  ARTICLE VIII

                                  MISCELLANEOUS

8.1  SEVERABILITY.

     It is the desire and intent of the parties hereto that the provisions of
this Agreement be enforced to the fullest extent permissible under the laws and
public policies applied in each jurisdiction in which enforcement is sought.
Accordingly, if any particular provision of this Agreement shall be adjudicated
by a court of competent jurisdiction to be invalid, prohibited or unenforceable
for any reason, such provision, as to such jurisdiction, shall be ineffective,
without invalidating the remaining provisions of this Agreement or affecting the
validity or enforceability of this Agreement or affecting the validity or
enforceability of such provision in any other jurisdiction. Notwithstanding the
foregoing, if such provision could be more narrowly drawn so as not to be
invalid, prohibited or unenforceable in such jurisdiction, it shall, as to such
jurisdiction, be so narrowly drawn, without invalidating the remaining
provisions of this Agreement or affecting the validity or enforceability of such
provision in any other jurisdiction.

8.2  ENTIRE AGREEMENT.

     This Agreement and the other Documents or agreements referred to herein and
to be executed and delivered in connection herewith embody the entire agreement
and understanding among the parties hereto with respect to the subject matter
hereof and thereof and supersede and preempt any and all prior and
contemporaneous understandings, agreements, arrangements or representations by
or among the parties, written or oral, which may relate to the subject matter
hereof or thereof in any way. Other than this Agreement, the other Documents and
the other agreements or instruments referred to herein and to be executed and
delivered in connection herewith, there are no other agreements continuing in
effect relating to the subject matter hereof, including preemptive rights,
rights of first refusal, voting of capital stock of the Company or election of
members of the Board.

8.3  INDEPENDENCE OF AGREEMENTS, COVENANTS, REPRESENTATIONS AND WARRANTIES.

     All agreements and covenants hereunder shall be given independent effect so
that if a certain action or condition constitutes a default under a certain
agreement or covenant, the fact that such action or condition is permitted by
another agreement or covenant shall not affect the occurrence of such default,
unless expressly permitted under an exception to such initial agreement or
covenant. In addition, all representations and warranties hereunder shall be
given independent effect so that if a particular representation or warranty
proves to be incorrect or is breached, the fact that another representation or
warranty concerning the same or similar subject matter is correct or is not
breached will not affect the incorrectness of or a breach of a representation
and warranty hereunder. The exhibits and schedules attached hereto are hereby
made part of this Agreement in all respects.

8.4  SUCCESSORS AND ASSIGNS.

     Except as otherwise provided herein, this Agreement will bind and inure to
the benefit of and be enforceable by the Company and its successors and assigns
and the Stockholders and any subsequent holders of Stockholder Shares and the
respective successors and assigns of each of them, so long as they hold
Stockholder Shares. None of the provisions hereof shall create, or be construed
or deemed to create, any right to employment in favor of any Person by the
Company or any of its Subsidiaries.

8.5  COUNTERPARTS; FACSIMILE SIGNATURES; VALIDITY.

     This Agreement may be executed in any number of counterparts, and each such
counterpart hereof shall be deemed to be an original instrument, but all such
counterparts together shall constitute but one agreement. Facsimile counterpart
signatures to this Agreement shall be acceptable and binding. The failure of any
Stockholder to execute this agreement does not make it invalid as against any
other Stockholder.

8.6  REMEDIES.

          (a) Each Stockholder shall have all rights and remedies reserved for
such Stockholder pursuant to this Agreement and all of the rights which such
Stockholder has under any law or equity. Any Person having any rights under any
provision of this Agreement will be entitled to enforce such rights
specifically, to recover damages by reason of any breach of any provision of
this Agreement and to exercise all other rights granted by law or equity.

          (b) The parties hereto agree that if any parties seek to resolve any
dispute arising under this Agreement pursuant to a legal proceeding, the
prevailing parties to such proceeding shall be entitled to receive reasonable
fees and expenses (including reasonable attorneys' fees and expenses) incurred
in connection with such proceedings.

          (c) It is acknowledged that it will be impossible to measure in money
the damages that would be suffered by any party hereto if any Person also party
hereto fails to comply with any of the obligations imposed on it upon them in
this Agreement or in the Restated Certificate or By-laws and that in the event
of any such failure, the aggrieved party will be irreparably damaged and will
not have an adequate remedy at law. Any such aggrieved party shall, therefore,
be entitled to equitable relief, including specific performance, to enforce such
obligations, and if any action should be brought in equity to enforce any of the
provisions of this Agreement, none of the parties hereto shall raise the defense
that there is an adequate remedy at law.

8.7  NOTICES.

conflict of law provision or rule that would cause the application of the laws

8.9  WAIVER OF JURY TRIAL.

     EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY
JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO
THIS AGREEMENT.

8.10 MEDIATION; CONSENT TO JURISDICTION.

          (a) Except as provided herein, no civil action with respect to any
dispute, claim or controversy arising out of this Agreement may be commenced
until the matter has been submitted to JAMS, or its successor, for mediation.
Any party hereto may commence mediation by providing to JAMS and the other
parties a written request for mediation, setting forth the subject of the
dispute and the relief requested. The parties will cooperate with JAMS and with
one another in selecting a mediator from JAMS' panel of neutrals, and in
scheduling the mediation proceedings. The parties' covenant that they will
participate in the mediation in good faith. Subject to SECTION 8.6(b), each
party shall pay it own attorneys' fees, costs and expenses in connection with
the mediation and share equally in the fees and expenses charged by JAMS. All
offers, promises, conduct and statements, whether oral or written, made in the
course of the mediation by any of the parties, their agents, employees, experts
and attorneys, and by the mediator and any JAMS employees, are confidential,
privileged and inadmissible for any purpose, including impeachment, in any
litigation or other proceeding involving the parties, PROVIDED that evidence
that is otherwise admissible or discoverable shall not be rendered inadmissible
or non-discoverable as a result of its use in the mediation. Either party may
seek equitable relief prior to the mediation to preserve the status quo pending
the completion of that process. Except for such an action to obtain equitable
relief, neither party may commence a civil action with respect to the matters
submitted to mediation until after the completion of the initial mediation
session, or 60 days after the date of filing the written request for mediation,
whichever occurs first. Mediation may continue after the commencement of a civil
action, if the parties so desire.

          (b) Each of the parties hereto irrevocably submits to the
non-exclusive jurisdiction of (a) the Supreme Court of the State of New York,
New York County and (b) the United States District Court for the Southern
District of New York, for the purposes of any suit, action or other proceeding
arising out of this Agreement or the transactions contemplated hereby. Each of
the

                                      -28-
<Page>

parties hereto further agrees that service of any process, summons, notice
or document by U.S. registered mail to such party's respective address set forth
in SECTION 8.7 shall be effective service of process for any action, suit or
proceeding in the State of New York with respect to any matters to which it has
submitted to jurisdiction in this SECTION 8.10(b). Each of the parties hereto
irrevocably and unconditionally waives any objection to the laying of venue of
any action, suit or proceeding arising out of this Agreement or the transactions
contemplated hereby and thereby in (a) the Supreme Court of the State of New
York, New York County or (b) the United States District Court for the Southern
District of New York, and hereby and thereby further irrevocably and
unconditionally waives and agrees not to plead or claim in any such court that
any such action, suit or proceeding brought in any such court has been brought
in an inconvenient forum.

8.11 FURTHER ASSURANCES.

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

8.12 CONFLICTING AGREEMENTS.

     No Stockholder shall maintain or otherwise enter into any stockholder
agreements or arrangements of any kind with any Person with respect to any
Stockholder Shares on terms inconsistent with the provisions of this Agreement
(whether or not such agreements or arrangements are with other Stockholders or
with Persons that are not parties to this Agreement), including agreements or
arrangements with respect to the acquisition or disposition of Stockholder
Shares in a manner which is inconsistent with this Agreement.

8.13 THIRD PARTY RELIANCE.

     Anything contained herein to the contrary notwithstanding, except for
SECTION 4.4 hereof the covenants of the Company contained in this Agreement (a)
are being given by the Company as an inducement to the Stockholders to enter
into this Agreement and the other Documents (and the Company acknowledges that

subject to or resulting in indemnification under this Agreement or otherwise.

                B.      LATE PAYMENT. Any payment not received by its due date
        shall result in a five (5%) percent charge to Lessee which shall be due

                C.      OPERATION OF BUSINESS. If Lessee, at any time after the
        commencement of this Lease, fails to keep the premises open for
        business, it will keep the premises clean and maintained and well lit.

        requirements, orders, directions, rules and regulations (referred to
        generally as "regulations") of governmental authorities having or
        claiming jurisdiction over the premises or the conduct of Lessee's
        business. Lessee may contest in good faith, after notice to Lessor, by
        appropriate proceedings conducted promptly at Lessee's own expense, in
        Lessee's name (and/or whenever necessary and with Lessor's consent, in
        Lessor's name), the validity or enforcement of any such regulation;
        provided that (i) such contest or any associated deferment of payment
        does not subject Lessor to a fine or other criminal liability, or
        subject the premises to any encumbrance; (ii) Lessee diligently
        prosecutes such contest to a final determination by the governing
        authority; and (iii) Lessee furnishes Lessor with any security that
        Lessor may reasonably request in connection with such contest.

        13.     ASSIGNMENT AND SUBLETTING.

                A.      Lessee and Lessee shall have the right to assign this
        Lease, and Lessee shall have the right to sublease the whole or any part
        of the Premises; provided, however, on any assignment or subletting by
        Lessee, Lessee must get the written consent of Lessor, which shall not
        be unreasonably withheld. Lessor shall notify Lessee of its decision not
        to consent to the assignment or subletting within twenty (20) days of
        receipt of the written request of Lessee or consent will be deemed to
        have been given by Lessor. No assignment or sublease shall release
        Lessee from any of its obligations under this Lease, nor shall any
        assignment by Lessor of this Lease release Lessor from its obligations
        incurred prior to such assignment. In the event of an assignment of this
        Lease by Lessor, any such assignee shall promptly furnish Lessee with
        its federal taxpayer identification number.

                B.      In the event this Lease is assigned or sublet by Lessee,
        and should any default occur requiring notice, Lessor agrees that it
        will furnish Lessee with a copy of such notice at the same time it is
        sent to such assignee or sublessee. If such default is not corrected by
        such assignee or sublessee during the specified time periods, Lessee
        shall have an additional period of thirty (30) days to correct such
        default, and upon correction of such default, Lessee shall have the
        right and option to resume actual possession of the Premises as Lessee
        hereunder for the unexpired term of this Lease.

        14.     INSPECTION. Lessor may enter upon the Leased Premises at any
reasonable time for the purpose of inspecting the Leased Premises. Also, Lessor
shall be permitted to show the Leased Premises to prospective purchasers within
twenty-four (24) hours' notice from Lessor to Lessee.

        15.     INDEMNITY AND INSURANCE.

                A.      Except for claims or demands for events caused by or
        resulting from the sole negligence of Lessor, Lessee agrees to indemnify
        and save Lessor harmless from and against any and all claims and demands
        arising from any negligence of Lessee, or its contractors, licensees,
        agents, servants or employees, or arising from any accident, injury or
        damages whatsoever caused to any person or property occurring in or on
        the Leased Premises or any part of them, and any and all actions, suits
        and proceedings in connection with any such claim or demand and any and
        all loss, damage, expense and liability incurred in or in connection
        with any such claim or demand, including attorneys' fees and court
        costs.

                B.      Lessee shall procure and maintain a policy or policies
        of comprehensive liability insurance, including property damage,
        covering the Leased Premises and its use and occupation by Lessee,
        insuring against liability for injuries to persons and property and for
        death of any person or persons occurring in or about the Leased
        Premises. The liability under such insurance shall not be less than Five
        Hundred Thousand Dollars ($500,000.00) for property damage and Two
        Million Dollars ($2,000,000.00) for personal injuries or deaths
        occurring in or about the Leased Premises. Lessee agrees to

                                        4
<Page>

        have Lessor listed as an additional insured and shall furnish a
        certificate of insurance to Lessor.

                C.      Lessor shall give Lessee notice of all claims made
        against the Lessor that come within the scope of the indemnification of
        this Paragraph, and shall not settle any such claim without the Lessee's
        written consent which shall not be unreasonably withheld. Unless
        objected to by an insurer of the Lessee that acknowledges primary
        responsibility for the claim, the Lessee shall conduct the defense of
        the claim. The Lessor shall cooperate with the Lessee in defending the
        claim, including, without limitation, providing documents, witnesses and
        other sources of information within its reasonable control.

        16.     DAMAGE OR DESTRUCTION.

                A.      During the Lease Term, Lessor shall, maintain in full
        force a policy or policies of full standard fire and extended coverage
        and vandalism insurance covering the Leased Premises in an amount equal
        to the full replacement costs of the improvements (and six (6) months of
        loss rents).

                B.      If the Leased Premises are damaged or destroyed by fire
        or other casualty during the Term, or any renewal thereof, the Lessee
        shall fully repair and restore the same within one hundred eighty (180)
        days after such damage or destruction (contingent upon receipt of the
        insurance proceeds for such repair) to substantially the same or better
        condition as existed prior to such damage or destruction. During such
        repair and restoration, Lessee shall be entitled to abatement of rent
        for damage or destruction which prohibits the use of the Premises.

                C.      The Lessor and the Lessee shall each cooperate in good
        faith coordinating any repair and restoration of the Leased Premises.

                D.      Lessee shall reimburse Lessor in advance during each
        year of this Lease for the cost of the insurance required in this
        paragraph. Such reimbursement shall be made on an annual basis within
        thirty (30) days after receipt of a written statement covering the
        insurance costs for each year of this Lease.

                E.      Notwithstanding the provisions of subparagraph (b)
        above, if the Leased Premises is substantially (over 70%) damaged or
        destroyed, then Lessor shall have the option to terminate this Lease
        upon notice to Lessee, given within thirty (30) days following such
        damage or destruction, in which latter event this Lease shall terminate
        effective as of the date of such damage or destruction.

                F.      Notwithstanding the provisions of subparagraph (b)
        above, if the Leased Premises is substantially (over 70%) damaged or
        destroyed then Lessee shall have the option to terminate this Lease upon
        notice to Lessor, given within thirty (30) days following such damage or
        destruction, in which latter event, this Lease shall terminate effective
        as of the date of such damage or destruction.

        provisions of this Paragraph, then

or any part of the Leased Premises, or ingress, egress or parking in connection
therewith or any interest therein by reason of any exercise of the power of
eminent domain, whether by a condemnation proceeding or otherwise, or any
transfer made in avoidance of an exercise of the power of eminent domain (all of
the foregoing being hereafter referred to as the "appropriation") prior to or
during the term hereof (or any extension or renewal thereof), the rights and
obligations of Lessor and Lessee with respect to such appropriation shall be as
hereinafter provided. In the event of an appropriation of all of the Leased
Premises, except for a temporary period of more than seven (7) days, this Lease
shall terminate as of the date of such appropriation. In the event of an
appropriation of less than all of the Leased Premises, if the appropriation
shall include (i) any substantial portion of the Improvements located on the
Premises or (ii) more than twenty percent (20%) of the parking spaces located on
the Leased Premises then in any such event Lessee shall have the option to
terminate this Lease; provided, however, that Lessor shall have thirty (30) days
to replace any parking spaces lost in a location immediately adjacent to the
Leased Premises. Any such election shall be made by written notice given on or
before thirty (30) days after appropriation. Any such election shall be
effective the date the condemnor takes title or possession, whichever occurs
first. Whether or not this Lease is terminated pursuant to this Paragraph,
Lessee shall be entitled to pursue an award for loss of business, for the loss
of its leasehold advantage and for costs of removing fixtures and equipment,
without, however, impairing or diminishing any fights of Lessor to claim loss
for the taking of, or injury or damage to, the Leased Premises, its reversionary
interest in the Leased Premises or any other fights or interest it may have in
and to this Lease, the Leased Premises and the Improvements thereon.

        18.     DEFAULT:

                A.      The occurrence of any of the following shall constitute
        a default by Lessee:

                        (i)     Failure to pay Rent or any monetary sum due by
                Lessee hereunder on the dates provided herein.

                        (ii)    Failure to perform any other provisions of this
                Lease if the failure to perform is not cured within thirty (30)
                days after written notice has been given to Lessee. If the
                default cannot reasonably be cured within 30 days, Lessee shall
                not be in default of this Lease, if Lessee commences to cure the
                default within the 30 day period and diligently and in good
                faith continues to pursue a cure of the default.

                B.      Lessor shall have the following remedies in case of
        Lessee default:

                        (i)     To collect by suit or otherwise each installment
                of Rent or other sum as it becomes due hereunder, or to enforce
                by suit or otherwise any other term or provision hereof on the
                part of Lessee required to be performed.

                        (ii)    To terminate this Lease, in which event this
                Lease shall terminate and Lessee shall surrender immediately
                possession of the Leased Premises, and pay to Lessor all
                expenses Lessor may incur by reason of the default, including
                the cost of recovering the Leased Premises, and the sum of

                                (a)     The unpaid Rent which had been accrued
                        at the time of termination; and

                                (b)     The present value of all remaining rent
                        due and payable under the for any unexpired term
                        discounted at the rate of seven (7%) percent per annum.

                remedies, Lessor shall have all rights, without limitation, to

written approval" of either Lessor or Lessee is referred to in this Lease, it is
understood and agreed that such consent shall not be unreasonably withheld or

stated in writing. If the party whose consent or approval is required does not
deny such consent or approval in written notice stating the reason for such
denial within twenty (20) days from the date of the request for such consent or
approval, such consent or approval shall be deemed to have been given.

        20.     DEFAULT. Should there be any default or breach of this Lease on
the part of Lessor, Lessee shall give Lessor written notice thereof, and should
Lessor fail to correct such breach or default within thirty (30) days after
notice, Lessee may remedy such breach or default and deduct the reasonable cost,
including interest on the same, from rentals due or to become due Lessor, or
