hundred five percent (105%) of the sum of the principal amount to be redeemed
plus any accrued but unpaid interest thereon;

                  (c)  if such voluntary redemption, including a redemption

Convertible Subordinated Notes such notice shall also state that the Noteholders
have the right to convert the Convertible Subordinated Notes at any time prior
to such redemption. Each redemption of the Notes pursuant to sub-Sections 2.5.1
and 2.5.2 shall be made so that the Notes then held by each holder shall be
redeemed in a principal amount which shall bear the same ratio to the total
unpaid principal amount being redeemed on all the Notes as the unpaid principal
amount of the Notes then held by such holder bears to the aggregate unpaid
principal amount of the Notes then outstanding.

            2.5.4.   MANDATORY REPURCHASE OF NOTES. As soon as possible, and in
any event within five (5) Business Days after the occurrence of a Mandatory
Repurchase Event, Borrower shall furnish to each Noteholder written notice
setting forth in reasonable detail the facts and circumstances underlying such

Notes held by such Noteholder at one hundred percent (100%) of the principal
amount thereof, on a date to be specified by Borrower, which date shall be not
less than thirty (30) days nor more than ninety (90) days after the occurrence

or any of the Notes, as applicable, held by it (in integral multiples of Five

accordance with its terms.

continuing, from and after the date such Event of Default has occurred the
entire outstanding unpaid principal balance of the Notes and any unpaid interest
from time to time in default shall bear interest, payable on demand in cash, at
the rate of sixteen percent (16%) per annum, compounded quarterly, or such lower
rate as then may be the maximum rate permitted by applicable law; PROVIDED,

Event of Default is then continuing, the Notes shall again bear interest at the
rate of twelve percent (12%) per annum as set forth in Section 2.1.

Notes shall require Borrower to pay interest at a rate in excess of the maximum

be due on a day which is not a Business Day, such payment may be made on the
next succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest due.

     2.9.   TRANSFER AND EXCHANGE OF NOTES. The holder of any Note, as
applicable, may, prior to maturity or prepayment thereof, surrender such Note at
the principal office of Borrower for transfer or exchange. Any holder desiring
to transfer or exchange any Note shall first notify Borrower in writing at least
five (5) days in advance of such transfer or exchange. Within a reasonable time
after such notice to Borrower from a holder of its intention to make such
exchange and without expense (other than transfer taxes, if any) to such holder,
Borrower shall issue in exchange therefor another Note in denominations of One
Hundred Thousand Dollars ($100,000) and multiples thereof, except in the case of
a Note for the balance of the aggregate amount of the Note, or Notes so
transferred which shall be in a minimum denomination of One Hundred Thousand
Dollars ($100,000), all as requested by the holder, for the same aggregate
principal amount, as of the date of such issuance, as the unpaid principal
amount of the Note or Notes so surrendered and having the same maturity and rate
of interest, containing the same provisions and subject to the same terms and
conditions as the Note or Notes so surrendered (provided that no minimum shall
apply to a liquidating distribution of Notes to investors in a Noteholder and
any Notes so distributed may be subsequently transferred by such investor and
its successors in the original denomination thereof without restriction under
this sentence). Each new Note shall be made payable to such Person or Persons,
or assigns, as the holder of such surrendered Note may designate, and such
transfer or exchange shall be made in such a manner that no gain or loss of
principal or interest shall result therefrom. Borrower shall have no obligation
hereunder or under any Note to any person other than the registered holder of
each such Note. Notwithstanding anything to the contrary contained herein, no
Noteholder shall be permitted to transfer any of its Notes unless such
Noteholder's transferee has agreed in writing to be bound by the terms of this
Agreement and the other Subordinated Notes Documents, including the
representations and warranties set forth in Article IV hereof.

     2.10.  REPLACEMENT OF NOTES. Upon receipt of evidence satisfactory to

requested in the case of any such loss, theft or destruction, upon delivery of

Borrower, or, in the case of any such mutilation, upon surrender and
cancellation of such Note, Borrower will issue a new Note of like tenor and
amount and dated the date to which interest has been paid, in lieu of such lost,
stolen, destroyed or mutilated Note; PROVIDED, HOWEVER, if any Note of which a
Noteholder, its nominee, or any of its partners is the holder is lost, stolen or
destroyed, the affidavit of an authorized partner or officer of the holder
setting forth the circumstances with respect to such loss, theft or destruction
shall be accepted as satisfactory evidence thereof, and no indemnification bond
or other security shall be

                                       12
<Page>

required as a condition to the execution and delivery by Borrower of a new Note
in replacement of such lost, stolen or destroyed Note other than the holders
written agreement to indemnify Borrower.

provide written notice to each Noteholder at least thirty (30) Business Days
prior to the occurrence or closing of a Mandatory Repurchase Event or a public
offering of securities by Borrower setting forth in reasonable detail the facts
and circumstances underlying such Mandatory Repurchase Event or public offering.

     2.12.  PERFORMANCE OF OBLIGATIONS. Borrower agrees that its obligations

continuance of an Event of Default, at the request of the Noteholders, Borrower
shall deliver a letter addressed to such accountants instructing them to comply
with the provisions of this sub-Section 6.3.3.

     6.4.   MAINTENANCE OF PROPERTY; INSURANCE.

            6.4.1.   PROPERTY. Borrower shall keep, and cause its Subsidiaries
to keep, all property necessary in the business of Borrower or each such
Subsidiary in good working order and condition, ordinary wear and tear excepted.

            6.4.2.   INSURANCE. Borrower shall maintain, and cause its
Subsidiaries to maintain, with responsible insurance companies, such insurance
coverage as shall be required by all laws, governmental regulations and court
decrees and orders applicable to it and such other insurance, to such extent and
against such hazards and liabilities, as is customarily maintained by companies
similarly situated; PROVIDED that in any event, such

                                       24
<Page>

insurance shall insure against all risks and liabilities of the type insured
against as of the Closing Date.

                  (a)  LOSS PAYEE; ADDITIONAL INSURED. Borrower shall cause its
policies of all such casualty insurance to contain standard lender loss payable
provisions and additional insured clauses issued in favor of the Noteholders as
the Noteholders' may request their interests to appear. Upon the request of a
majority of the Noteholders, Borrower shall furnish to the Noteholders a
certificate setting forth in reasonable detail the nature and extent of all
insurance maintained by Borrower and any applicable Subsidiary. Prior to the
Closing Date, Borrower shall cause each issuer of an insurance policy to provide
the Noteholders with an endorsement (i) showing the Noteholders as a loss payee
with respect to each policy of property or casualty insurance and naming the
Noteholders as an additional insured with respect to each policy of liability
insurance, (ii) providing that 30 days' notice will be given to the Noteholders
prior to any cancellation of, or reduction or change in coverage provided by or
other material modification to such policy and (iii) being reasonably acceptable
in all other respects to the Noteholders. Borrower hereby appoints the
Noteholders as its attorney-in-fact, exercisable at its option, to endorse any
check which may be payable to Borrower in order to collect the proceeds of such
insurance, and, to the extent such check is payable to a Subsidiary of Borrower,
Borrower shall cause the appropriate person for such Subsidiary to appoint
Noteholders as such Subsidiary's attorney-in-fact.

                  (b)  RIGHT TO PURCHASE INSURANCE. Unless Borrower provides the
Noteholders with evidence of the continuing insurance coverage required by this
Agreement upon the request of a majority of the Noteholders, the Noteholders may
purchase insurance at Borrower's expense to protect the Noteholders' interest in
the Collateral. This insurance may, but need not, protect Borrower's and any
Subsidiary's interests. The coverage that the Noteholders purchase may, but need
not, pay any claim that is made against Borrower or any Subsidiary in connection
with the Collateral. Borrower may later cancel any insurance purchased by the
Noteholders, but only after providing the Noteholders with evidence that
Borrower has obtained the insurance coverage required by this Agreement. If the
Noteholders purchase insurance for the Collateral, as set forth above, Borrower
will be responsible for the costs of that insurance, including interest and any
other charges that may be imposed with the placement of the insurance, until the
effective date of the cancellation or expiration of the insurance and the costs
of the insurance may be added to the principal amount of the Loans owing
hereunder.

                  (c)  BUSINESS INTERRUPTION INSURANCE. Borrower shall, or shall
cause its Subsidiaries to, obtain and maintain, and shall deliver to the
Noteholders upon their request evidence of, public liability and business
interruption insurance in such amounts as is customary for entities in the same
or similar businesses located in the same or similar area.

Subsidiaries to comply, with any and all laws, ordinances, governmental rules
and regulations, and court or administrative orders or decrees to which any such
Person is

                                       25
<Page>

subject, whether federal, state or local, and shall obtain and maintain any and
all licenses, permits, franchises, certificates of need, or other governmental
authorizations necessary to the ownership of such Person's Property or to the
conduct of its businesses, which violation or failure to obtain may materially
adversely affect the business, Property, or financial conditions of Borrower,
the Property or Noteholders' rights with respect to the Property.

     6.6.   EXISTENCE, RIGHTS AND PROPERTIES. Borrower shall do (or cause to be
done) all things necessary to preserve and keep in full force and effect its,
and each of its Subsidiaries' (unless Borrower's board of directors elects not
to continue such Subsidiary's existence), legal existence, good standing, rights
and franchises. Borrower (i) will cause all of its properties and those of its
Subsidiaries used or useful in the conduct of its business or the business of
its Subsidiaries to be maintained and kept in good condition, repair and working
order, ordinary wear and tear excepted, to the extent such properties, in the
reasonable estimation of Borrower, remain necessary for the operation of
Borrower's business, and (ii) will cause to be made all necessary repairs,
renewals, replacements, betterments and improvements thereof, all as in the
judgment of Borrower may be necessary so that the business carried on in
connection therewith may be properly conducted at all times.

applicable Subsidiaries to maintain, each Pension Plan in substantial compliance

Hazardous Substances and the remediation of such real property or other assets
as is necessary to comply in all material respects with all Environmental Laws
and to preserve the value of such real property or other assets. Without
limiting the generality of the foregoing, Borrower shall, and shall cause each
Subsidiary to, comply with each Federal or state judicial or administrative
order requiring the performance at any real property by Borrower or any
Subsidiary of activities in response to the release or threatened release of a
Hazardous Substance.

     6.9.   LITIGATION. Borrower will, and will cause each of its Subsidiaries
to, give notice to the Noteholders in writing within fifteen (15) days of
becoming aware of any litigation or proceedings threatened in writing or any
pending litigation and proceedings affecting Borrower or any of its Subsidiaries
or to which Borrower or any of its Subsidiaries is or becomes a party involving

reasonably be expected to have a Material Adverse Effect and stating the nature
and status of such litigation or proceedings.

            6.10.1.  TRANSACTION RELATED. Borrower shall pay all taxes (other
than taxes based upon or measured by the Noteholders' income or revenues), if

any new, or the discontinuance of any existing, place of business.

     6.13.  VERIFICATION OF INFORMATION. All information concerning Borrower and
its Affiliates that is provided to the Noteholders will be true and complete in
all material respects and will not omit to state a material fact necessary to
make the statements contained in such information, in light of the circumstances
under which they were made, not misleading.

     6.14.  RESERVED.

material Intellectual Property owned, used or developed by Borrower and its
Subsidiaries in the conduct of their respective businesses, and that it will not
do any act, or omit to do any act, nor permit any licensee to do any act,

            8.3.1.   The Noteholders holding greater than fifty percent (50%),
voting together as a single class, in principal amount of the Notes may, by
notice to Borrower, declare the entire unpaid principal amount of the Notes plus
all interest accrued and unpaid thereon and all other amounts payable under this
Agreement to be forthwith due and payable, whereupon the Notes, all such accrued
interest and all such amounts shall become and be forthwith due and payable
(unless there shall have occurred an Event of Default under sub-Sections 8.1.9,
8.1.10, or 8.1.11, in which case all such amounts shall automatically become due
and payable), without presentment, demand, protest or further notice of any
kind, all of which are hereby expressly waived by Borrower.

            8.3.2.   In the case of events of default under Section 8.1, each
Noteholder may proceed to protect and enforce its rights by suit in equity,
action at law and/or other appropriate proceeding either for specific

this Agreement.

            8.3.3.   In case any one or more of the Events of Default shall have
occurred and be continuing, and whether or not the Noteholders shall have

and enforce its rights by suit in equity, action at law or other appropriate
proceeding, whether for the specific performance of any covenant or agreement
contained in this Agreement and the other Subordinated Notes Documents or any
instrument pursuant to which the Obligations to such Noteholder are evidenced,
including to the extent permitted by applicable law by obtaining the ex parte
appointment of a receiver, and, if such amount shall have become due, by
declaration or otherwise, by proceeding to enforce the payment thereof or any
other legal or equitable right of such Noteholder. No remedy herein conferred
upon any Noteholder is intended to be exclusive of any other remedy and each and
every remedy shall be cumulative and shall be in addition to every other remedy
given hereunder or now or hereafter existing at law or in equity or by statute
or any other provision of law.

     8.4.   NATURE OF REMEDIES. All rights and remedies granted to the
Noteholders hereunder and under the Notes and the Related Agreements, or
otherwise available at law or in equity, shall be deemed concurrent and
cumulative, and not alternative remedies, and the Noteholders may proceed with
any number of remedies at the same time until all Obligations are satisfied in
full. The exercise of any one right or remedy shall not be deemed a waiver or
release of any other right or remedy, and the Noteholders, upon or at any time
after the occurrence of an Event of Default, may proceed against Borrower at any
time, under any agreement, with any available remedy and in any order.

     8.5.   SET-OFF. If any bank account or other Property held by or with the
Noteholders or any Affiliate of the Noteholders is attached or otherwise liened
or levied upon by any third party, the Noteholders shall have and be deemed to
have, without notice to Borrower, the immediate right of set-off and may apply
the funds or other

                                       34
<Page>

amounts or property thus set off against any of the Obligations hereunder then

occurrence or during the continuance of any Event of Default, any Noteholder
receives any monies with respect to the amounts due hereunder, such monies shall
be distributed for application as follows:

            8.6.1.   First, to the payment of, or (as the case may be) the
reimbursement of the Noteholders for or in respect of all reasonable costs,
expenses, disbursements and losses which shall have been incurred or sustained
by the Noteholders in connection with the collection of such monies by the
Noteholders, for the exercise, protection or enforcement by the Noteholders of
all or any of the rights, remedies, powers and privileges of the Noteholders
under this Agreement or any of the other Subordinated Notes Documents pro rata
based on the relative amounts so incurred or sustained by the Noteholders;

            8.6.2.   Second, to all other Obligations in such order or
preference as the Noteholders may determine; PROVIDED, HOWEVER, that
distributions shall be made among the Noteholders pro rata; and

            8.6.3.   Third, to Borrower or to such other Persons as are entitled
thereto.

                           ARTICLE IX - MISCELLANEOUS

     9.1.   NO WAIVER; CUMULATIVE REMEDIES. No failure or delay on the part of
any Noteholder, in exercising any right, power or remedy hereunder shall operate
as a waiver thereof, nor shall any single or partial exercise of any such right,
power or remedy preclude any other or further exercise thereof or the exercise
of any other right, power or remedy hereunder. The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

     9.2.   AMENDMENTS, WAIVERS AND CONSENTS. Any provision in this Agreement or
the Notes or the other Subordinated Notes Documents to the contrary
notwithstanding, changes in or additions to this Agreement may be made, and
compliance with any covenant or provision herein set forth may be omitted or
waived, if Borrower shall, as long as any Notes are outstanding, obtain consent
thereto in writing from the holder or holders of greater than fifty percent
(50%), considered together as a single class, of the aggregate principal amount
of all Notes then outstanding, and shall, in any case, deliver copies of such
consent in writing to all other holders of Notes; PROVIDED that no such consent
shall be effective to reduce or to postpone the date fixed for the payment of
the principal (including any required redemption) or interest payable on any
Note without the consent of the holder thereof, or to alter or amend any
provisions relating to prepayments, mandatory purchase or the terms of
subordination contained in this Agreement and the other Subordinated Notes
Documents, or to alter or amend the consent mechanism provided for under this
Section 9.2.

            70 Willow Road, Suite 100
            Menlo Park, California 94025
            Attention: Jeffrey T. Chambers and Todd R. Crockett

            If to any other holder of the Notes:

            at such holder's address for notice as set forth in the transfer
            records of Borrower

or, as to each of the foregoing, at such other address as shall be designated by
such Person in a written notice to the other party complying as to delivery with
the terms of this Section 9.3. All such notices, requests, demands and other
communications shall, when mailed or sent, respectively, be effective (i) three
(3) days after being deposited in the mails or (ii) one Business Day after being
deposited with the express overnight courier service or sent by electronic
facsimile transmission (with receipt confirmed), respectively, addressed as
aforesaid.

     9.4.   COSTS, EXPENSES AND TAXES. Borrower agree to pay on demand all
reasonable costs and expenses of the Noteholders in connection with the
preparation, execution and delivery of this Agreement, the Notes, the other
Subordinated Notes Documents and other instruments and documents to be delivered
hereunder, and in connection with the consummation of the transactions
contemplated hereby and thereby, as well as all reasonable costs and expenses of
the Noteholders in connection with the amendment, waiver (whether or not such
amendment or waiver becomes effective) or enforcement of this Agreement, the
Notes, the other Subordinated Notes Documents, and other instruments and
documents to be delivered hereunder and thereunder.

     9.5.   ASSIGNABILITY; BINDING AGREEMENT. This Agreement may not be assigned
by any party hereto without the prior written consent of each other party
hereto; PROVIDED, HOWEVER, that any Noteholder may assign this Agreement freely
without consent to any transferee permitted under Section 2.9. This Agreement
shall be binding upon and enforceable by, and shall inure to the benefit of, the
parties hereto and their

                                       36
<Page>

respective successors and permitted assigns, and no others. Notwithstanding the
foregoing, nothing in this Agreement is intended to give any Person not named
herein the benefit of any legal or equitable right, remedy or claim under this
Agreement.

     9.6.   PAYMENTS IN RESPECT OF NOTES. Each Noteholder and any successor
holder of any Notes, by their acceptance thereof, agree that, with respect to
all sums received by them applicable to the payment of principal of or interest
on the Notes, equitable adjustment will be made among them so that, in effect,
all such sums shall be shared ratably by all of the holders of the Notes,
whether received by voluntary payment, by the exercise of the right of set off,
by counterclaim or cross-action or by the enforcement of any or all of the
Notes. If any holder of the Notes receives any payment on its Notes in excess of
its pro rata portion, then such holder receiving such excess payment shall
purchase for cash from the other holders an interest in their Notes in such
amounts as shall result in a ratable participation by all of the holders in the
aggregate unpaid amount of Notes then outstanding. Borrower shall not have any
obligation to any Person under this Section 9.6.

     9.7.   INDEMNIFICATION. In addition to the payment of the Noteholders'
expenses required pursuant to this Agreement, whether or not the transactions
contemplated hereby shall be consummated, Borrower agrees to jointly and
severally indemnify, pay and hold each Noteholder and the partners, members,
officers, directors, employees and agents of each Noteholder (collectively, the
"INDEMNITEES") harmless from and against, any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, claims, costs, expenses
and disbursements of any kind or nature whatsoever (including, without
limitation, the reasonable fees and disbursements of counsel for such
Indemnitees in connection with any investigative, administrative or judicial
proceedings, whether or not such Indemnitees shall be designated a party
thereto), which may be imposed on, incurred by, or asserted against such
Indemnitee, in any manner relating to or arising out of (i) this Agreement, the
other Subordinated Notes Documents, the Related Agreements and all other matters
related thereto in connection therewith, (ii) the Noteholders' agreement to
purchase the Notes, or the use or intended use of the proceeds of the Notes
hereunder, (iii) the violation of any securities law by Borrower or any of its
Subsidiaries, or (iv) the failure of any of the parties (other than the
Noteholders) to the Related Agreements to comply with any law, rule or
regulation applicable to the transactions contemplated thereby (the "INDEMNIFIED
LIABILITIES"); PROVIDED that Borrower shall have no obligation to an Indemnitee
hereunder with respect to Indemnified Liabilities which are determined by a
final court decision to have resulted from the gross negligence or willful
misconduct of that Indemnitee. To the extent that the undertaking to indemnify,
pay and hold harmless set forth in the preceding sentence may be unenforceable
because it is violative of any law or public policy, Borrower shall contribute
the maximum portion which it is permitted to pay and satisfy under applicable
law to the payment and satisfaction of all Indemnified Liabilities incurred by
the Indemnitees or any of them.

     9.8.   SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations and
warranties made to the Noteholders in this Agreement, the other Subordinated
Notes Documents, the Related Agreements and any other instrument or document
delivered in

                                       37
<Page>

connection herewith or therewith, shall survive the execution and delivery
hereof and thereof, regardless of any investigation made by the Noteholders or
on behalf of the Noteholders.

     9.9.   PRIOR AGREEMENTS. This Agreement and the Related Agreements
constitute the entire agreement between the parties and supersede any prior
understandings or agreements concerning the subject matter hereof or thereof.

     9.10.  SEVERABILITY. The invalidity or unenforceability of any provision
hereof shall in no way affect the validity or enforceability of any other
provision.

     9.11.  GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York, without giving effect to
conflict of laws principles thereof.

     9.12.  DISPUTE RESOLUTION

            (a)   All disputes, claims, or controversies arising out of or
     relating to this Agreement or any other Subordinated Notes Document that
     are not resolved by mutual agreement shall be resolved solely and
     exclusively by binding arbitration to be conducted before
     J.A.M.S./Endispute, Inc. in New York, New York before a single arbitrator
     (the "Arbitrator"). The parties understand and agree that this arbitration
     shall apply equally to claims of fraud or fraud in the inducement.

            (b)   The parties covenant and agree that the arbitration shall
     commence within one hundred and eighty (180) days of the date on which a
     written demand for arbitration is filed by any party hereto (the "Filing
     Date"). In connection with the arbitration proceeding, the Arbitrator shall
     have the power to order the production of documents by each party and any
     third-party witnesses. In addition, each party may take up to three
     depositions as of right, and the Arbitrator may in his or her discretion
     allow additional depositions upon good cause shown by the moving party.
     However, the Arbitrator shall not have the power to order the answering of
     interrogatories or the response to requests for admission. In connection
     with any arbitration, each party shall provide to the other, no later than
     seven (7) business days before the date of the arbitration, the identity of
     all persons that may testify at the arbitration and a copy of all documents
     that may be introduced at the arbitration or considered or used by a
     party's witnesses or experts. The Arbitrator's decision and award shall be
     made and delivered within two hundred and forty (240) days of the Filing
     Date. The Arbitrator's decision shall set forth a reasoned basis for any
     award of damages or finding of liability. The Arbitrator shall not have
     power to award damages in excess of actual compensatory damages and shall
     not multiply actual damages or award punitive damages or any other damages
     that are specifically excluded under this Agreement, and each party hereby
     irrevocably waives any claim to such damages.

                                       38
<Page>

            (c)   The parties covenant and agree that they will participate in
     the arbitration in good faith and that they will, except as provided in
     Section 9.4 and 9.7 of this Agreement, (i) bear their own attorneys' fees,
     costs and expenses in connection with the arbitration, and (ii) share
     equally in the fees and expenses charged by the Arbitrator. Any party
     unsuccessfully refusing to comply with an order of the Arbitrators shall be
     liable for costs and expenses, including attorneys' fees, incurred by the
     other party in enforcing the award. This Section 9.12 applies equally to
     requests for temporary, preliminary or permanent injunctive relief, except
     that in the case of temporary or preliminary injunctive relief any party
     may proceed in court in accordance with Section 9.16 hereof without prior
     arbitration for the purpose of avoiding immediate and irreparable harm.

     9.13.  CONSENT TO JURISDICTION. Except as provided in Section 9.12(c) and
9.16, each of the parties hereto irrevocably and unconditionally consents to the
jurisdiction of J.A.M.S./Endispute, Inc. to resolve all disputes, claims or
controversies arising out of or relating to this Agreement or any other
Subordinated Notes Document, and further consents to the sole and exclusive
jurisdiction of the courts of Colorado and California for the purposes of
enforcing the arbitration provisions of Section 9.12 of this Agreement. Each
party further irrevocably waives any objection to proceeding before the
Arbitrator based upon lack of personal jurisdiction or to the laying of venue
and further irrevocably and unconditionally waives and agrees not to make a
claim in any court that arbitration before the Arbitrator has been brought in an
inconvenient forum. Each of the parties hereto hereby consents to service of
process by registered mail at the address to which notices are to be given. Each
of the parties hereto agrees that its submission to jurisdiction and its consent
to service of process by mail is made for the express benefit of the other
parties hereto.

     9.14.  COUNTERPARTS. This Agreement may be executed simultaneously in any
number of counterparts, each of which when so executed and delivered shall be
taken to be an original, but such counterparts shall together constitute but one
and the same document.

     9.15.  FURTHER ASSURANCES. From and after the date of this Agreement, upon
the request of the Noteholders, Borrower and its Subsidiaries shall execute and
deliver such instruments, documents and other writings as may be reasonably
necessary or desirable to confirm and carry out and to effectuate fully the
intent and purposes of the Subordinated Notes Documents.

     9.16.  SPECIFIC PERFORMANCE. Subject to Section 9.12(c), upon breach or
default by Borrower with respect to any obligation hereunder or under the Notes,
each Noteholder shall be entitled to protect and enforce its rights at law, or
in equity or by other appropriate proceedings for specific performance of such
obligation, or for an injunction against such breach or default, or in aid of
the exercise of any power or remedy granted hereby or thereby or by law.

     9.17.  ACTIONS BY NOTEHOLDERS. Except as provided in Section 9.2, wherever
in this Agreement action is required or permitted to be taken by, or consent is
required of, or

                                       39
<Page>

a matter requires the satisfaction of, the Noteholders, such action may be taken
by, such consent may be obtained from, or such satisfaction may be expressed by,
the holders of a majority, considered together as a single class, of the
aggregate principal amount of all Notes then outstanding.

     9.18.  LIMITATION OF LIABILITY. No Noteholder shall have any liability to
Borrower or Borrower's Subsidiaries (whether sounding in tort, contract, or
otherwise) for consequential damages suffered by Borrower or its Subsidiaries in
connection with, arising out of, or in any way related to the transactions or
relationships contemplated by the Subordinated Notes Documents, or any act,
omission or event occurring in connection therewith, or for any special
exemplary or punitive damages, and Borrower and its Subsidiaries hereby waive,
to the maximum extent not prohibited by law, any right they may have to claim or
recover any of the foregoing.

     9.19.  CONFIDENTIALITY AGREEMENT. Each Noteholder shall hold all financial
information of Borrower and its Subsidiaries and other non-public information
obtained from Borrower pursuant to the requirements of this Agreement in
accordance with such Noteholder's customary procedures for handling confidential
information of this nature; PROVIDED, HOWEVER, any Noteholder may disclose such
confidential information (a) to its examiners, affiliates, outside auditors,
counsel and other professional advisors, (b) to any prospective transferees and
assignees of its rights thereunder, (c) in connection with any proceeding or
action to enforce such Noteholder's rights hereunder or in connection herewith
or with the Related Transactions, and (d) as required or requested by any
Governmental Authority or representative thereof or pursuant to legal process;
PROVIDED, FURTHER, that in no event shall any Noteholder be obligated to return
any materials furnished by Borrower or any Subsidiary. For the purposes of this
Section 9.18, the term "GOVERNMENTAL AUTHORITY" shall mean the government of any
nation, state, city, locality or other political subdivision of any thereof, any
entity exercising executive, legislative, judicial, regulatory or administrative
functions of or pertaining to government, and any corporation or other entity
owned or controlled, through stock or capital ownership or otherwise, by any of
the foregoing.
