          4.   ADMINISTRATION OF THE PLAN.

               (a) ADMINISTRATOR. The Plan shall be administered by the Board or

                                        4

<Page>

                    (ii)   to select the Service Providers to whom Options,
     Stock Purchase Rights, SARs and Restricted Stock Awards may from time to
     time be granted hereunder;

                    (iii)  to determine the number of Shares to be covered by
     each such award granted hereunder;

                    (iv)   to approve forms of agreement for use under the Plan;

                    (v)    to determine the terms and conditions, of any Option,
     Stock Purchase Right, SAR or Restricted Stock Award granted hereunder.
     Such terms and conditions include, but are not limited to, the exercise
     price, the time or times when Options, Stock Purchase Rights, SARs or
     Restricted Stock Awards may be exercised (which may be based on
     performance criteria), any vesting acceleration or waiver of forfeiture
     restrictions, and any restriction or limitation regarding any Option,
     Stock Purchase Right, SAR or Restricted Stock Award or the Common Stock
     relating thereto, based in each case on such factors as the
     Administrator, in its sole discretion, shall determine;

                    (vi)   to determine whether and under what circumstances an
     Option may be bought out in cash under subsection 9(e);

                    (vii)  to reduce the exercise price of any Option, Stock
     Purchase Right or SAR to the then current Fair Market Value if the Fair
     Market Value of the Common Stock covered by such Option, Stock Purchase
     Right or SAR has declined since the date the Option, Stock Purchase
     Right or SAR was granted;

                    (viii) to initiate an Option Exchange Program;

                    (ix)   to prescribe, amend and rescind rules and regulations
     relating to the Plan, including rules and regulations relating to sub-plans
     established for the purpose of qualifying for preferred tax treatment under
     foreign tax laws;

                    (x)    to allow Optionees to satisfy withholding tax
     obligations by electing to have the Company withhold from the Shares to
     be issued upon exercise of an Option, Stock Purchase Right or SAR that
     number of Shares having a Fair Market Value equal to the amount required
     to be withheld. The Fair Market Value of the Shares to be withheld shall be
     determined on the date that the amount of tax to be withheld is to be
     determined. All elections by Optionees to have Shares withheld for this
     purpose shall be made in such form and under such conditions as the
     Administrator may deem necessary or advisable;

                    (xi)   to construe and interpret the terms of the Plan and
     awards granted pursuant to the Plan.

               (c)  EFFECT OF ADMINISTRATOR'S DECISION. All decisions,
determinations and interpretations of the Administrator shall be final and
binding on all Optionees.

          5.   ELIGIBILITY.

               (a)  Nonstatutory Stock Options, Stock Purchase Rights, SARs and
Restricted Stock Awards may be granted to Service Providers. Incentive Stock
Options may be granted only to Employees.

               (b) Each Option shall be designated in the Option Agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 5(b), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

               (c) Neither the Plan nor any Option, Stock Purchase Right, SAR or
Restricted Stock Award shall confer upon any Optionee any right with respect to
continuing the Optionee's relationship as a Service Provider with the Company,
nor shall it interfere in any way with his or her right or the Company's right
to terminate such relationship at any time, with or without cause.

          6.   TERM OF PLAN. The Plan shall become effective upon its adoption
by the Board. It shall continue in effect for a term of ten (10) years unless
sooner terminated under Section 14 of the Plan.

          7. TERM OF OPTION. The term of each Option shall be stated in the
Option Agreement; provided, however, that the term shall be no more than ten
(10) years from the date of grant thereof. In the case of an Incentive Stock
Option granted to an Optionee who, at the time the Option is granted, owns stock
representing more than ten percent (10%) of the voting power of all classes of
stock of the Company or any Parent or Subsidiary of the Company, the term of the
Option shall be five (5) years from the date of grant or such shorter term as
may be provided in the Option Agreement.

          8.   OPTION EXERCISE PRICE AND CONSIDERATION.

               (a) The per share exercise price for the Shares to be issued upon
exercise of an Option shall be such price as is determined by the Administrator,
but shall be subject to the following:

                    (i)    In the case of an Incentive Stock Option

                           (A)  granted to an Employee who, at the time of grant
          of such Option, owns stock representing more than ten percent (10%) of
          the voting power of all classes of stock of the Company or any Parent
          or Subsidiary of the Company, the exercise price shall be no less than
          110% of the Fair Market Value per Share on the date of grant.

                                        6

<Page>

                           (B) granted to any other Employee, the per Share
          exercise price shall be no less than 100% of the Fair Market Value per
          Share on the date of grant.

                    (ii) In the case of a Nonstatutory Stock Option, the per
     Share exercise price shall be determined by the Administrator.

                    (iii) Notwithstanding the foregoing, Options may be granted
     with a per Share exercise price other than as required above pursuant to a
     merger or other corporate transaction.

               (b) The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant). Such consideration may consist of (1) cash,
(2) check, (3) promissory note, (4) other Shares which (x) in the case of Shares
acquired upon exercise of an Option, have been owned by the Optionee for more
than six months on the date of surrender, and (y) have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which such Option shall be exercised, (5) consideration received by the Company
under a cashless exercise program implemented by the Company in connection with
the Plan, or (6) any combination of the foregoing methods of payment. In making
its determination as to the type of consideration to accept, the Administrator
shall consider if acceptance of such consideration may be reasonably expected to
benefit the Company.

          9.   EXERCISE OF OPTION.

               (a) PROCEDURE FOR EXERCISE; RIGHTS AS A STOCKHOLDER. Any Option
granted hereunder shall be exercisable according to the terms hereof at such
times and under such conditions as determined by the Administrator and set forth
in the Option Agreement. Unless the Administrator provides otherwise, vesting of
Options granted hereunder shall be suspended during any unpaid leave of absence.
An Option may not be exercised for a fraction of a Share.

          Subject to Sections 17 and 18 below, an Option shall be deemed
exercised when the Company receives (i) written or electronic notice of exercise
(in accordance with the Option Agreement) from the person entitled to exercise
the Option, and (ii) full payment for the Shares with respect to which the
Option is exercised. Full payment may consist of any consideration and method of
payment authorized by the Administrator and permitted by the Option Agreement
and the Plan. Shares issued upon exercise of an Option shall be issued in the
name of the Optionee or, if requested by the Optionee, in the name of the
Optionee and his or her spouse. Until the Shares are issued (as evidenced by the
appropriate entry on the books of the Company or of a duly authorized transfer
agent of the Company), no right to vote or receive dividends or any other rights
as a stockholder shall exist with respect to the Shares, notwithstanding the
exercise of the Option. The Company shall issue (or cause to be issued) such
Shares promptly after the Option is exercised. No adjustment will be made for a
dividend or other right for which the record date is prior to the date the
Shares are issued, except as provided in Section 14 of the Plan.

                                        7

<Page>

          Exercise of an Option in any manner shall result in a decrease in the
number of Shares thereafter available, both for purposes of the Plan and for
sale under the Option, by the number of Shares as to which the Option is
exercised.

               (b) TERMINATION OF RELATIONSHIP AS A SERVICE PROVIDER. If an
Optionee ceases to be a Service Provider, such Optionee may exercise his or her
Option within such period of time as is specified in the Option Agreement to the
extent that the Option is vested on the date of termination (but in no event
later than the expiration of the term of the Option as set forth in the Option
Agreement). In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for three (3) months following the Optionee's
termination. If, on the date of termination, the Optionee is not vested as to
his or her entire Option, the Shares covered by the unvested portion of the
Option shall revert to the Plan. If, after termination, the Optionee does not
exercise his or her Option within the time set forth above, or within the time
specified by the Administrator, if later, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

               (c) DISABILITY OF OPTIONEE. If an Optionee ceases to be a Service
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option Agreement
to the extent the Option is vested on the date of termination (but in no event
later than the expiration of the term of such Option as set forth in the Option
Agreement). In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the Optionee's
termination. If, on the date of termination, the Optionee is not vested as to
his or her entire Option, the Shares covered by the unvested portion of the
Option shall revert to the Plan. If, after termination, the Optionee does not
exercise his or her Option within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

               (d) DEATH OF OPTIONEE. If an Optionee dies while a Service
Provider, the Option may be exercised within such period of time as is specified
in the Option Agreement to the extent that the Option is vested on the date of
death (but in no event later than the expiration of the term of such Option as
set forth in the Option Agreement) by the Optionee's estate or by a person who
acquires the right to exercise the Option by bequest or inheritance. In the
absence of a specified time in the Option Agreement, the Option shall remain
exercisable for twelve (12) months following the Optionee's termination. If, at
the time of death, the Optionee is not vested as to the entire Option, the
Shares covered by the unvested portion of the Option shall immediately revert to
the Plan. If the Option is not so exercised within the time specified herein,
the Option shall terminate, and the Shares covered by such Option shall revert
to the Plan.

               (e) BUYOUT PROVISIONS. The Administrator may at any time offer to
buy out for a payment in cash or Shares, an Option previously granted, based on
such terms and conditions as the Administrator shall establish and communicate
to the Optionee at the time that such offer is made.

          10.  RESTRICTED STOCK AWARDS. Restricted Stock Awards shall be subject
to the terms, conditions, and restrictions determined by the Administrator at
the time the Restricted

                                        8

<Page>

Stock is awarded and set forth in the applicable Award Agreement, if any. The
Administrator may require the recipient to sign an Award Agreement as a
condition of the award, but may not require the recipient to pay any money
consideration (other than any applicable tax withholding amount). The agreement
may contain such terms, conditions, representations and warranties as the
Administrator may require. The certificates representing the shares of Stock
awarded shall bear such legends as shall be determined by the Administrator.

          11.  STOCK APPRECIATION RIGHTS.

               (a) GRANT OF SARs. Subject to the terms and conditions of the
Plan, SARs may be granted to Service Providers at any time and from time to time
as shall be determined by the Administrator, in its sole discretion. The
Administrator shall have complete discretion to determine the number of SARs
granted to any Participant.

               (b) EXERCISE PRICE AND OTHER TERMS. The Administrator, subject to
the provisions of the Plan, shall have complete discretion to determine the
terms and conditions of SARs granted under the Plan. However, the exercise price
of an SAR shall be not less than one hundred percent (100%) of the Fair Market
Value of a Share on the grant date.

               (c) SAR AGREEMENT. Each SAR grant shall be evidenced by an award
agreement that shall specify the exercise price, the term of the SAR, the
conditions of exercise, and such other terms and conditions as the
Administrator, in its sole discretion, shall determine.

               (d) EXPIRATION OF SARs. A SAR granted under the Plan shall expire
upon the date determined by the Administrator, in its sole discretion, and set
forth in the Award Agreements.

               (e)  PAYMENT OF SAR AMOUNT. Upon exercise of a SAR, a Participant
shall be entitled to receive payment from the Company in an amount determined by
multiplying:

                    (i)    The difference between the Fair Market Value of a
     Share on the date of exercise over the exercise price; times

                    (ii)   The number of Shares with respect to which the SAR is
     exercised.

               (f) PAYMENT UPON EXERCISE OF SAR. At the discretion of the
Administrator, payment for a SAR may be in cash, Shares with a Fair Market Value
equal to the amount determined in paragraph (e) above or a combination thereof.

               (g) CASH SETTLEMENTS AND PLAN SHARE ALLOCATION. Cash payments of
Stock Appreciation Rights as well as Common Stock issued upon exercise of Stock
Appreciation Rights shall be applied against the maximum number of shares of
Common Stock that may be issued pursuant to the Plan, The number of shares to be
applied against such maximum number of shares in such circumstances shall be the
number of shares equal to the amount of the cash payment divided by the Fair
Market Value of a Share on the date the Stock Appreciation Right is granted.

          12. NON-TRANSFERABILITY OF OPTIONS, STOCK PURCHASE RIGHTS, SARs AND
RESTRICTED STOCK AWARDS. Unless determined otherwise by the Administrator, the
Options, Stock Purchase Rights, SARs and Restricted Stock Awards may not be
sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner
other than by will or by the laws of descent or distribution and may be
exercised, during the lifetime of the Optionee, only by the Optionee. Any
transferee by will or by the laws of descent or distribution shall be required
to acknowledge and agree that such transferee is subject to all of the terms of
the Plan and the applicable Award Agreement as if such transferee had received
the applicable award.

          13.  STOCK PURCHASE RIGHTS.

               (a) RIGHTS TO PURCHASE. Stock Purchase Rights may be issued
either alone, in addition to, or in tandem with other awards granted under the
Plan and/or cash awards made outside of the Plan. After the Administrator
determines that it will offer Stock Purchase Rights under the Plan, it shall
advise the offeree in writing or electronically of the terms, conditions and
restrictions related to the offer, including the number of Shares that such
person shall be entitled to purchase, the price to be paid, and the time within
which such person must accept such offer. The offer shall be accepted by
execution of an Award Agreement in the form determined by the Administrator.

               (b) REPURCHASE OPTION. Unless the Administrator determines
otherwise, the Award Agreement shall grant the Company a repurchase option
exercisable upon the voluntary or involuntary termination of the purchaser's
service with the Company for any reason (including death or disability). Unless
the Administrator determines otherwise, the purchase price for Shares
repurchased pursuant to the Restricted Stock purchase agreement shall be the
original price paid by the purchaser and may be paid by cancellation of any
indebtedness of the purchaser to the Company. The repurchase option shall lapse
at such rate as the Administrator may determine.

               (c)  OTHER PROVISIONS. The Award Agreement shall contain such
other terms, provisions and conditions not inconsistent with the Plan as may be
determined by the Administrator in its sole discretion.

               (d) RIGHTS AS A STOCKHOLDER. Subject to Sections 17 and 18 below,
once the Stock Purchase Right is exercised, the purchaser shall have rights
equivalent to those of a stockholder and shall be a stockholder when his or her
purchase is entered upon the records of the duly authorized transfer agent of
the Company. No adjustment shall be made for a dividend or other right for which
the record date is prior to the date the Stock Purchase Right is exercised,
except as provided in Section 14 of the Plan.

          14.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, MERGER OR ASSET SALE.

               (a)  CHANGES IN CAPITALIZATION. Subject to any required approval
of the stockholders of the Company, and except as provided in (b) and (c) below,
in the event that the Administrator determines that any dividend or other
distribution (whether in the form of cash, Common Stock, other securities, or
other property), recapitalization, reclassification, stock split, reverse stock
split, reorganization, consolidation, split-up, spin-off, combination,
repurchase, or

                                       10

<Page>

exchange of Common Stock or other securities of the Company, issuance of
warrants or other rights to purchase Common Stock or other securities of the
Company, or other similar corporate transaction or event, effected without the
receipt of consideration by the Company in the Administrator's sole discretion,
affects the Common Stock such that an adjustment is determined by the
Administrator to be appropriate in order to prevent dilution or enlargement of
the benefits or potential benefits intended by the Company to be made available
under the Plan or with respect to any Option, Stock Purchase Right or SAR then
the Administrator shall, in such manner as it may deem equitable, adjust any or
all of:

                    (i) the number and kind of shares of Common Stock (or other
     securities or property) with respect to which Options, Stock Purchase
     Rights or SARs may be granted or awarded (including, but not limited to,
     adjustments of the limitations in Section 3 on the maximum number of shares
     which may be issued);

                    (ii) the number and kind of shares of Common Stock (or other
     securities or property) subject to outstanding Options, Stock Purchase
     Rights or SARs; and

                    (iii) the grant or exercise price with respect to any
     Option, Stock Purchase Right or SAR.

          The conversion of any convertible securities of the Company shall not
be deemed to have been "effected without receipt of consideration." Such
adjustment shall be made by the Administrator, whose determination in that
respect shall be final, binding and conclusive. Except as expressly provided
herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Stock subject to an Option, Stock Purchase Right, SAR or Restricted
Stock Award.

               (b) DISSOLUTION OR LIQUIDATION. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option, Stock Purchase Right or SAR until
fifteen (15) days prior to such transaction as to all of the Optioned Stock
covered thereby, including Shares as to which the Option, Stock Purchase Right
or SAR would not otherwise be exercisable. In addition, the Administrator may
provide that any Company repurchase option applicable to any Shares purchased
upon exercise of an Option, Stock Purchase Right or SAR shall lapse as to all
such Shares, provided the proposed dissolution or liquidation takes place at the
time and in the manner contemplated. To the extent it has not been previously
exercised, an Option, Stock Purchase Right or SAR will terminate immediately
prior to the consummation of such proposed transaction.

               (c) MERGER OR ASSET SALE. In the event of a merger of the Company
with or into another corporation, or the sale of substantially all of the assets
of the Company, except as otherwise provided in this paragraph (c), each
outstanding Option and Stock Purchase Right shall be assumed or an equivalent
option or right substituted by the successor corporation or a Parent or
Subsidiary of the successor corporation. In the event that the successor

                                       11

<Page>

corporation or its Parent or Subsidiary does not assume or substitute equivalent
options or rights, then to the extent not already vested or otherwise provided
in the Option Agreement each Optionee shall fully vest in and have the right to
exercise his or her Options, Restricted Stock or SARs as to all of the Optioned
Stock, including Shares as to which he or she would not otherwise be vested in
or exercisable. If an Option, Stock Purchase Right or SAR becomes fully vested
and exercisable in the event of a merger or sale of assets pursuant to the
foregoing sentence, then the Administrator shall notify the Optionee in writing
or electronically that such Option, Stock Purchase Right or SAR shall be fully
exercisable for a period of not less than fifteen (15) days from the date of
such notice, and the Option, Stock Purchase Right or SAR shall terminate upon
the expiration of such period. For the purposes of this paragraph, the Option,
Stock Purchase Right or SAR shall be considered assumed if, following the merger
or sale of assets, the option or right confers the right to purchase or receive,
for each Share of Optioned Stock subject to the Option, Stock Purchase Right or
SAR immediately prior to the merger or sale of assets, the consideration
(whether stock, cash, or other securities or property) received in the merger or
sale of assets by holders of Common Stock for each Share held on the effective
date of the transaction (and if holders were offered a choice of consideration,
the type of consideration chosen by the holders of a majority of the outstanding
Shares); provided, however, that if such consideration received in the merger or
sale of assets is not solely stock of the successor corporation or its Parent or
Subsidiary, the Administrator may, provide for the consideration to be received
upon the exercise of the Option, Stock Purchase Right or SAR, for each Share of
Optioned Stock subject to the Option, Stock Purchase Right or SAR, to be solely
stock of the successor corporation or its Parent or Subsidiary equal in fair
market value to the per share consideration received by holders of Shares in the
merger or sale of assets. An Option Agreement may provide for vesting and
exercisability in full of an Option, Restricted Stock, Stock Purchase Right or
SAR upon a merger or sale of assets regardless of whether a successor or any
Parent or Subsidiary thereof assumes such Option Stock Purchase Right or SAR. In
such event , the vesting and exercisability of such Option, Restricted Stock,
Stock Purchase Right or SAR shall be governed by the terms and conditions of
such Option Agreement, notwithstanding the terms set forth above in this Section
14(c).

          15. TIME OF GRANTING OPTIONS, STOCK PURCHASE RIGHTS, SARS AND
RESTRICTED STOCK. The date of grant of an Option, Stock Purchase Right, SAR or
Restricted Stock Award shall, for all purposes, be the date on which the
Administrator makes the determination granting such Option, Stock Purchase
Right, SAR or Restricted Stock Award, or such other date as is determined by the
Administrator. Notice of the determination shall be given to each Service
Provider to whom an Option, Stock Purchase Right, SAR or Restricted Stock Award
is so granted within a reasonable time after the date of such grant.

          16.  AMENDMENT AND TERMINATION OF THE PLAN.

               (a)  AMENDMENT AND TERMINATION. The Board may at any time amend,
alter, suspend or terminate the Plan.

               (b)  STOCKHOLDER APPROVAL. The Board shall obtain stockholder
approval of any Plan amendment to the extent necessary and desirable to comply
with Applicable Laws.

                                       12

<Page>

               (c) EFFECT OF AMENDMENT OR TERMINATION. No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to Options granted under the
Plan prior to the date of such termination.

          17.  CONDITIONS UPON ISSUANCE OF SHARES.

               (a) LEGAL COMPLIANCE. Shares shall not be issued pursuant to the
exercise of an Option, Stock Purchase Right or SAR unless the exercise of such
Option, Stock Purchase Right or SAR and the issuance and delivery of such Shares
shall comply with Applicable Laws and shall be further subject to the approval
of counsel for the Company with respect to such compliance.

               (b) INVESTMENT REPRESENTATIONS. As a condition to the exercise of
an Option, Stock Purchase Right or SAR, the Administrator may require the person
exercising such Option, Stock Purchase Right or SAR to represent and warrant at
the time of any such exercise that the Shares are being purchased only for
investment and without any present intention to sell or distribute such Shares
if, in the opinion of counsel for the Company, such a representation is
required.

          18. INABILITY TO OBTAIN AUTHORITY. The Company shall use commercially
reasonable efforts to obtain authority from any regulatory body having
jurisdiction, which authority is deemed by the Company's counsel to be necessary
to the lawful issuance and sale of any Shares hereunder. The inability of the
Company to obtain such authority shall relieve the Company of any liability in
respect of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained.

          19.  RESERVATION OF SHARES. The Company, during the term of this Plan,
shall at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

          20.  STOCKHOLDER APPROVAL. The Plan shall be subject to approval by
the stockholders of the Company within twelve (12) months after the date the
Plan is adopted. Such stockholder approval shall be obtained in the degree and
manner required under Applicable Laws.

          21. RIGHTS AND RESTRICTIONS ON SHARES. The Shares acquired upon
exercise of an Option or Stock Purchase Right granted under the Plan shall be
subject to such terms and conditions as the Administrator shall determine in its
sole discretion, including, without limitation, the following rights and
restrictions:

               (a)  COMPANY'S RIGHT OF FIRST REFUSAL. Subject to subsection (b)
below, before any Shares held by an Optionee or any permitted transferee (each,
a "Holder") may be sold, pledged, assigned, hypothecated, transferred, or
otherwise disposed of (each, a "Transfer"), the Company or its assignee(s) shall
have a right of first refusal to purchase the Shares on the terms and conditions
set forth in this Section (the "Right of First Refusal"). Such

                                       13

<Page>

Right of First Refusal shall terminate as to all Shares upon the first to occur
of (i) the Public Trading Date or (ii) a merger or sale of the Company with a
publicly traded company as described in Section 14(c).

               (b) NOTICE OF PROPOSED TRANSFER. The Holder of the Shares shall
deliver to the Company at least sixty (60) days prior to making a Transfer a
written notice (the "Transfer Notice") stating: (A) the Holder's bona fide
intention to sell or otherwise Transfer such Shares; (B) the name of each
proposed purchaser or other transferee ("Proposed Transferee"); (C) the proposed
sale price and (D) the number of Shares to be Transferred to each Proposed
Transferee, and the Holder shall offer the Shares at the then Fair Market Value
to the Company or its assignee(s).

               (c) EXERCISE OF RIGHT OF FIRST REFUSAL. During the thirty (30)
days after receipt of the Transfer Notice, the Company may elect in writing to
purchase all, but not less than all, of the Shares proposed to be Transferred to
any one or more of the Proposed Transferees. If the Company does not elect to
purchase all of the Shares proposed to be Transferred within such thirty (30)
day period, the Investors may elect to purchase all, but not less than all, of
the Shares proposed to be Transferred by delivering a written notice of such
election to the Holder within sixty (60) days after the receipt of the Transfer
Notice by the Company. If more than one Investor elects to purchase such Shares,
the number of Shares to be purchased by the electing Investors shall be
allocated among them pro rata on the basis of the number of shares of the
Company's Class B Common Stock on an "As Converted Ownership" (as defined in the
Company's Certificate of Incorporation) basis by them. The purchase price will
be determined in accordance with clause (iii) below.

               (d)  PURCHASE PRICE. The purchase price ("Purchase Price") for
the Shares repurchased under this Section shall be the then Fair Market Value.

               (e) PAYMENT. Payment of the purchase price shall be made, at the
option of the Company or its assignee(s), in cash (by check), by cancellation of
all or a portion of any outstanding indebtedness of the Holder to the Company
(or, in the case of repurchase by an assignee, to the assignee), or by any
combination thereof within thirty (30) days after receipt of the Transfer Notice
or in the manner and at the times set forth in the Transfer Notice.

               (f) HOLDER'S RIGHT TO TRANSFER. If all of the Shares proposed in
the Transfer Notice to be transferred to a given Proposed Transferee are not
purchased by the Company and/or its assignee(s) as provided in this Section,
then the Holder may sell or otherwise transfer such Shares to that Proposed
Transferee at the then Fair Market Value or at the sale price set forth in the
Transfer Notice, provided that (A) such sale or other Transfer is consummated
within one hundred twenty (120) days after the date of the Transfer Notice, (B)
any such sale or other Transfer is effected in accordance with any applicable
securities laws, (C) the Proposed Transferee agrees in writing that the
provisions of this Section shall continue to apply to the Shares in the hands of
such Proposed Transferee, and (D) prior to making any Transfer, the Holder shall
use reasonable efforts to ascertain whether the Proposed Transferee(s) or any
person or entity affiliated with the Proposed Transferee(s) is a competitor of
the Company and if Holder has reason to believe that the Proposed Transferee is
or is affiliated with or acting on behalf of such a competitor, the Holder shall
not transfer any Shares to the Proposed Transferee. If the

                                       14

<Page>

Shares described in the Transfer Notice are not Transferred to the Proposed
Transferee within such 120 day period, a new Transfer Notice shall be given to
the Company, and the Company and/or its assignees shall again be offered the
Right of First Refusal as provided herein before any Shares held by the Holder
may be sold or otherwise Transferred.

               (g) EXCEPTION FOR CERTAIN FAMILY TRANSFERS. Notwithstanding any
provision in the Plan to the contrary, the Transfer of any or all of the Shares
during the Holder's lifetime to a Family Member (as defined below) or the
Transfer on the Holder's death by will or intestacy to anyone shall be exempt
from the Right of First Refusal; PROVIDED, HOWEVER, that any Transfer by the
Holder during the Holder's lifetime to the Holder's Family Member shall be
without payment of any consideration whatsoever and must be approved in advance
by the Administrator. In such case, the transferee or other recipient shall
receive and hold the Shares so Transferred subject to the provisions of this
Section 21, and there shall be no further Transfer of such Shares except in
accordance with the terms of this Section 21. "FAMILY MEMBER" means, and is
limited to, any child, stepchild, grandchild, parent, stepparent, grandparent,
spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law,
son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including
adoptive relationships, any person sharing the Holder's household (other than a
tenant or employee), a trust in which these persons have more than fifty percent
of the beneficial interest, a foundation in which these persons (or the Holder)
control the management of assets, and any other entity in which these persons
(or the Holder) own more than fifty percent of the voting interests.

          22.  GOVERNING LAW. The validity and enforceability of this Plan shall
be governed by and construed in accordance with the laws of the State of
Delaware without regard to otherwise governing principles of conflicts of law.

                                  Adopted by and approved by the shareholders of
                                  Orbitz, Inc. on April 10, 2002

                                CHICAGO, ILLINOIS

     AGREEMENT OF LEASE made as of this 1st day of October, 2000 (hereinafter
referred to as the "Lease") between 200 South Wacker Drive, L.L.C., an Illinois
limited liability company (hereinafter referred to as "Landlord"), and ORBITZ,
LLC, a Delaware limited liability company, whose present address is 200 South
Wacker Drive, Suite 1900, Chicago, Illinois 60606 (hereinafter referred to as
"Tenant");

                                   WITNESSETH:

     Landlord hereby agrees to Lease to Tenant, and Tenant hereby agrees to
accept, the premises (hereinafter referred to as the "Premises") designated on
the plan attached hereto as Exhibit A and commonly described as the entirety of
the eighteenth (18th) and nineteenth (19th) floors containing approximately
44,766 square feet of "Rentable Area" in the aggregate in the building known as
200 South Wacker Drive (hereinafter referred to as the "Building") located on a

together with all present and future easements, additions, improvements and

on the eighteenth (18th) floor portion of the Premises pursuant to the Work
Letter attached hereto as Exhibit C ("Work Letter"), (the "Commencement Date"),
and shall end on the last day of the eighty-fourth (84th) full calendar month
thereafter (hereinafter referred to as the "Termination Date"), unless sooner
terminated (or extended) as provided herein; provided, however if substantial
completion of the Work on the eighteenth (18th) floor is delayed because of any
"Tenant Delay" (as such term is defined in the Work Letter), the Commencement
Date shall be the date on which substantial completion would have occurred but
for any Tenant Delay. At the time of substantial completion of the Work on the
eighteenth (18th) floor, Landlord and Tenant shall execute a written memorandum
confirming the Commencement Date and the Termination Date. The mutual

                                       -1-
<Page>

determination of Landlord's architect or interior space planner for the Building
and Tenant's architect shall be final and conclusive on Landlord and Tenant as
to whether the Work has been substantially completed. Upon substantial
completion by Landlord of the Work on the eighteenth (18th) floor, Tenant shall
within seventy-two (72) hours thereafter vacate the nineteenth (19th) floor and
relocate to the eighteenth (18th) floor so that Landlord may thereafter commence
construction of the Work on the nineteenth (19th) floor. Notwithstanding
anything herein to the contrary, if the Work on the eighteenth (18th) floor is
not substantially complete by June 2001 for any reason other than due to a
"Tenant Delay" as defined in the Workletter or due to causes beyond the
reasonable control of Landlord, then Tenant may elect to terminate this Lease by
delivering written notice thereof to Landlord at any time after June 1, 2001 and
before the date the Work on the eighteenth (18th) floor is substantially
complete; provided, however, that such termination shall not be effective if
Landlord delivers written notice to Tenant, within ten (10) days after receipt
of Tenant's termination notice that Landlord will substantially complete the
Work on the eighteenth (18th) floor, and thereafter does complete the Work on
the eighteenth (18th) floor, within thirty (30) days after receipt of Tenant's
termination notice.

     2.      BASE RENT.

             A.     BASE RENT. Tenant shall pay to Landlord or Landlord's agent
at 200 South Wacker Drive, Chicago, Illinois, or at such other place as Landlord
may from time to time designate in writing, in currency which, at the time of
payment, is legal tender for private or public debts in the United States of
America, rent at the annual rate set forth in the schedule attached hereto as
Exhibit B and made a part hereof (hereinafter referred to as the "Base Rent") on
or before the first day of each and every month during the Term, without demand
and without any set-off or deduction whatsoever, except as otherwise expressly
set forth herein. Any Base Rent payable for a partial month shall be paid on a
pro rata basis based on the number of days in such partial month on the first
day of such month which falls within the Term. Each period of twelve (12) months
beginning on the Commencement Date or on any anniversary thereof and ending on
the day before the following anniversary of the Commencement Date or on the
Termination Date, as the case may be, is hereinafter referred to as a "Lease
Year."

             B.     PARTIAL ABATEMENT OF BASE RENT AND ADDITIONAL RENT. If
Tenant has taken occupancy of that portion of the Premises comprising the
eighteenth (18th) floor of the Building for the purpose of carrying on its
business therein and if Tenant is not in "default" hereunder (as described in
Section 22 hereof) on the date any such installment is due, Base Rent and
Additional Rent due hereunder commencing on the Commencement Date with respect
to the portion of the Premises comprising the entirety of the nineteenth (19th)
floor shall be abated in full through April 30, 2001.

     3.      ADDITIONAL RENT.

             In addition to paying the Base Rent specified in Section 2 hereof,
Tenant shall pay as "Additional Rent" the amounts described in this Section 3.
Such Additional Rent paid by

                                       -2-
<Page>

Tenant and other tenants in the Building shall reimburse Landlord for all
expenses of operating and maintaining the Land and the Building, except as
expressly excluded below, and shall permit Landlord to receive the Base Rent as
"net" rent. The Base Rent and the Additional Rent are sometimes herein
collectively referred to as the "Rent." All Additional Rent shall be payable for
the same periods and in the same manner, time and place as the Base Rent.
Without limitation on other obligations of Tenant which shall survive the
expiration of the Term, the obligations of Tenant to pay Additional Rent and the
obligations of Landlord to credit or refund any overpayments shall survive the
expiration of the Term for a period of twenty-four (24) months. For any partial
Calendar Year, Tenant shall be obligated to pay only a pro rata share of the
Additional Rent for such Calendar Year, based on the number of days of the Term
falling within such Calendar Year.

             A.     DEFINITIONS. As used in this Section 3, the terms:

             (i)    "Calendar Year" shall mean each calendar year in which any
part of the Term falls, through and including the year in which the Term
expires.

             (ii)   "Tenant's Proportionate Share" shall mean 5.92%, being the
percentage calculated by dividing the Rentable Area contained in the Premises,
as determined by Landlord and shown on the first page of this Lease, by 756,600
rentable square feet (being the Rentable Area of the Building).

             (iii)  "Taxes" shall mean taxes levied, assessed or imposed against
Landlord (or which Landlord is obligated to pay on behalf of any other person or
entity having any interest in the Land or the Building) in connection with the
Land, the Building, the operation thereof or any rights or responsibilities
related thereto, except with respect to the off-site parking garage. "Taxes"
shall include without limitation: (a) real estate taxes and assessments, special
or otherwise, levied or assessed upon the Land or Building; (b) ad valorem taxes
for any personal property used in connection with the Land or Building; (c) any
tax, assessment, charge or fee which is imposed in substitution for, or in lieu
of an increase in, such real estate taxes and ad valorem personal property
taxes; (d) any income tax based solely on Landlord's income from the Land and
Building which taxes such income in a different manner than income from sources
other than the ownership and operation of income-producing real estate and which
is in lieu of real property taxes; or (e) a tax on rents or leases which is in
lieu of real property taxes. Taxes shall also include, in the year paid, all
fees for consultants and attorneys and all other costs incurred by Landlord in
seeking to obtain a reduction of, or a limit on the increase in, any Taxes,
regardless of whether any reduction or limitation is obtained. Taxes shall not
include any inheritance, estate, succession, transfer, gift, franchise, or
capital stock tax or any income taxes other than those described above, nor
shall Taxes include, so long as Tenant has paid Tenant's Proportionate Share of
Ownership Taxes in a timely manner as required hereunder, any interest or
penalties on account of Landlord's failure to pay such Taxes in a timely manner.
With respect to any Taxes which include assessments against income or property
not related to the Land or Building, Taxes shall include only that portion of
such Taxes which would be payable if the Land and Building and all rights
related thereto were the only assets of Landlord.

                                       -3-

             (iv)   "Operating Expenses" shall mean all expenses, costs and
disbursements (other than Taxes) of every kind and nature (determined for the
applicable Calendar Year on an accrual basis) paid or incurred by Landlord in
connection with the management, operation, maintenance and repair of the Land
and Building, except the following:

             a.     Costs of capital improvements to any tenant's premises;

             b.     Principal or interest payments on loans secured by mortgages
     or trust deeds on the Building or Land or rent payable on any ground lease
     of the Land;

             c.     Costs of capital improvements to the Building (including any
     improvements required to the common areas of the Building in order to
     comply with the provisions of the Americans With Disabilities Act of 1990
     (42 U.S.C. Section 12-101 et seq.) (the "ADA")), except that Operating
     Expenses shall include (a) the cost of any capital improvement completed on
     or after the Commencement Date which is intended to reduce any component of
     Operating Expenses, as evenly amortized over the useful life of each such
     capital improvement with interest on the unamortized amount at the lesser
     of the cost to Landlord for borrowing funds to finance such improvements or
     2% per annum above the prime rate or base rate or other comparable
     reference rate of interest announced from time to time by Bank One, N.A. or
     other bank designated by Landlord if Bank One is not at any time announcing
     a prime rate or base rate or other comparable reference rate (but in no
     event at a rate which is more than the highest lawful rate allowable in the
     State of Illinois); and (b) the cost of any capital improvement (other than
     an improvement required in order for the Building to comply with the ADA)
     which is made by Landlord to keep the Land or Building in compliance with
     all governmental rules and regulations applicable from time to time thereto
     and enacted, adopted or modified after the date of this Lease;

             d.     Real estate brokers' leasing commissions and attorneys' fees
     and expenses incurred in negotiating leases for space in the Building or
     handling disputes with tenants of the Building;

             e.     Payments of any other cost or expense to the extent to which
     Landlord is paid or reimbursed by any person (other than as reimbursement
     for Additional Rent pursuant to this Section 3);

             f.     All salaries and expenses for any of Landlord's employees
     above the level of property manager;

             g.     Costs (including, without limitation, attorneys' fees),
     fines or penalties incurred due to the violation by Landlord of applicable
     laws and regulations;

             h.     The cost of repairing or restoring any portion of the
     Building damaged by a casualty, except that Operating Expenses shall
     include the costs of repairs or other work

                                       -4-
<Page>

     occasioned by a casualty to the extent that such cost is not covered by
     Landlord's insurance described in Section 11 hereof because of any
     deductible amount, provided that the amount of such deductible is
     consistent with those maintained by owners of other first-class office
     buildings in the downtown Chicago area;

             i.     The cost of repairs, alterations or replacements required as
     the result of the exercise of any right of eminent domain, to the extent
     Landlord has received an award therefor;

             j.     Costs of paintings, sculptures and other artwork within the
     Building;

             k.     Costs and expenses incurred to remove, contain or otherwise
     remedy Hazardous Materials (as defined in Section 4.D hereof);

             l.     Costs incurred in connection with the sale, financing,
     refinancing, mortgaging or other change of ownership of the Land or the
     Building;

             m.     Payments to affiliates of Landlord for goods or services in
     excess of what would be paid to nonaffiliated parties for such goods or
     services in an arm's length transaction; and

             n.     Costs and expenses in connection with the installation,
     operation and maintenance of any health club or restaurant facility in the
     Building.

             B.     EXPENSE ADJUSTMENT. Tenant shall pay to Landlord or
Landlord's agent as Additional Rent, an amount ("Expense Adjustment Amount")
equal to Tenant's Proportionate Share of the amount of Operating Expenses
incurred with respect to each Calendar Year plus Tenant's pro rata share of the
special allocation of Operating Expenses to occupied premises if Section 3D is
applicable for such Calendar Year. The Expense Adjustment Amount with respect to
each Calendar Year shall be paid in monthly installments during such Calendar
Year in an amount estimated from time to time by Landlord (but in no event shall
Landlord revise such estimate more than two (2) times in any Calendar Year) and
communicated by written notice to Tenant. Landlord shall cause to be kept books
and records showing Operating Expenses in accordance with an appropriate system
of accounts and accounting practices consistently maintained. Within six (6)
months following the close of each Calendar Year, Landlord shall cause the
amount of the Expense Adjustment Amount for such Calendar Year to be computed
based on Operating Expenses for such Calendar Year and shall deliver to Tenant a
statement of such amount plus a statement of all estimated installments paid by
Tenant with respect to such Calendar Year. Tenant shall pay to Landlord any
deficiency shown by such statement within thirty (30) days after receipt of such
statement. If the installments paid exceed the amount due, and if Tenant is not
then in default (beyond the expiration of any applicable cure period) hereunder,
Landlord shall either credit the excess against payments of Base Rent and
Additional Rent next due to Landlord from Tenant hereunder or, at Tenant's
option, refund the excess to Tenant within thirty (30) days following Landlord's
determination. Delay in computation of the

                                       -5-
<Page>

Expense Adjustment Amount shall not be deemed a default hereunder or a waiver of
Landlord's right to collect the Expense Adjustment Amount.

             C.     TAX ADJUSTMENT. Tenant shall pay to Landlord or Landlord's
agent as Additional Rent, an amount ("Tax Adjustment Amount") equal to Tenant's
Proportionate Share of the amount of Taxes incurred with respect to each
Calendar Year. The Tax Adjustment Amount with respect to each Calendar Year
shall be paid in monthly installments during such Calendar Year in an amount
estimated from time to time by Landlord (but in no event shall Landlord revise
such estimate more than two (2) times in any Calendar Year) and communicated by
written notice to Tenant. If any portion of Taxes for any Calendar Year is
payable in whole or in part before the end of such Calendar Year, Tenant shall,
within thirty (30) days after the written request of Landlord, promptly pay its
Proportionate Share of such payment as a special installment, after deducting
installments previously paid by Tenant under this Section 3C for such Calendar
Year. Following the final payment of Taxes for each Calendar Year, Landlord
shall cause the amount of the Tax Adjustment Amount for such Calendar Year to be
computed and deliver to Tenant a statement of such amount plus a statement of
all estimated installments paid by Tenant for such Calendar Year. Tenant shall
pay to Landlord any deficiency shown by such statement within thirty (30) days
after receipt of such statement. If the installments paid exceed the actual
amount due, and if Tenant is not then in default (beyond the expiration of any
applicable cure period) hereunder, Landlord shall either credit the excess
against payments of Base Rent and Additional Rent next due to Landlord from
Tenant hereunder or, at Tenant's option, refund the excess to Tenant. The amount
of any refund of Taxes received by Landlord shall be credited against Taxes for
the year in which such refund is received. In determining the amount of Taxes
for any year, the amount of special assessments to be included shall be limited
to the amount of the installment (plus any interest payable thereon) of such
special assessment required to be paid during such year as if the Landlord had
elected to have such special assessment paid over the maximum period of time
permitted by law. All references to Taxes "for" a particular year shall be
deemed to refer to Taxes assessed for such year, notwithstanding that such Taxes
are billed and paid in a subsequent Calendar Year. Delay in computation of the
Tax Adjustment Amount shall not be deemed a default hereunder or a waiver of
Landlord's right to collect the Tax Adjustment Amount.

             D.     ALLOCATION OF OPERATING EXPENSES. If at any time during the
Term less than ninety-five percent (95%) of the then current Rentable Area of
the office section of the Building is occupied by tenants, at Landlord's option
those components of Operating Expenses which vary with occupancy shall be
removed from general Operating Expenses and allocated to the portion of the
Building which is actually occupied by tenants and generating such components of
Operating Expenses. Such special allocation shall be made on a pro rata basis
over the occupied Rentable Area in the office section of the Building, based on
both the comparative Rentable Areas of the occupied premises and the portion of
such Calendar Year during which such premises were occupied. Operating Expenses
which do not vary with occupancy, such as (i) public liability insurance, and
(ii) maintenance and heating and air conditioning costs for the lobby, will
continue to be allocated on a pro rata basis over the

                                       -6-
<Page>

Rentable Area of the office section of the Building whether or not occupied and
Tenant shall only be responsible for its Proportionate Share of such Operating
Expenses.

             E.     TENANT'S RIGHT TO EXAMINE LANDLORD'S BOOKS AND RECORDS. If
Tenant does not agree with or otherwise wishes to confirm the correctness of
Landlord's determination of Operating Expenses and Taxes for any Calendar Year,
then Tenant shall have the right to inspect such of Landlord's books and records
relative thereto during normal business hours and in the Office of the Building
if written request ("Tenant's Inspection Request") is given by Tenant to
Landlord not later than sixty (60) days following receipt of the statements
described in Sections 3B and 3C, as the case may be. Any photocopies of
Landlord's books and records which Tenant desires shall be coordinated by
Landlord and shall be made at Tenant's sole cost and expense. If the parties are
unable by negotiation to reach agreement with respect to Operating Expenses or
Taxes for the Calendar Year in question within forty-five (45) days following
Tenant's Inspection Request, then Tenant shall have the right to engage an
independent real estate consultant or certified public accountant mutually
satisfactory to Landlord and Tenant from an accounting firm with an office in
Chicago who is experienced in the accounting for Operating Expenses in
commercial office buildings in downtown Chicago (to be paid on an hourly and not
a contingent fee basis) to audit Landlord's records with respect to Operating
Expenses or Taxes. Upon engagement by Tenant of such accountant or consultant,
all activities of the accountant or consultant in connection with such audit
shall be undertaken upon the express direction and authorization of Tenant. In
the event such audit discloses (i) errors made during the prior Calendar Year
which, when totaled, establish that the sum overcharged to and paid by Tenant
exceeds five percent (5%) of the actual (as distinguished from estimated) amount
of Tenant's Proportionate Share of Operating Expenses or Taxes, as the case may
be, the audit shall be at the expense of Landlord, or (ii) no errors or an error
which equals or is less than five percent (5%), the audit shall be at the
expense of Tenant.

     The results of the audit (regardless of the degree of the error, if any)
shall be binding upon Landlord and Tenant and Landlord shall thereafter, if
appropriate, change its method of calculating Operating Expenses and Taxes
consistent with the results of the audit. If no Tenant's Inspection Request is
received by Landlord within sixty (60) days following receipt by Tenant of
Landlord's statement, or if Tenant shall not elect to cause an audit to be made
of Landlord's records by delivering written notice to Landlord of Tenant's
exercise of Tenant's audit right within forty-five (45) days after delivery of
Tenant's Inspection Request, then Landlord's statement shall conclusively be
deemed to have been approved and accepted by Tenant. Any amount shown by
Landlord's statement to be due to Landlord, whether or not Tenant's Inspection
Request is delivered to Landlord, shall be paid by Tenant as provided in
Sections 3B and 3C above, without prejudice to any such inspection request. If
Tenant timely delivers Tenant's Inspection Request, any charges disclosed by
such statement which Landlord agrees are irregular or improper or which are
thereafter determined to be in error shall be promptly corrected by Landlord,
and Tenant shall receive a credit against the next amounts of Rent due from
Tenant, or Landlord shall pay promptly such amounts due to Tenant, if such
determination is made after the end of the Term, so long as Tenant is not then
in monetary or other material non-monetary default hereunder (subject, however,
to Landlord's right to offset such amount by

                                       -7-
<Page>

any amounts owing from Tenant to Landlord under this Lease) for any overpayments
made by Tenant as a result of such irregularities or improper charges, or Tenant
shall promptly pay to Landlord any amounts determined to be due Landlord, as the
case may be.

     Tenant acknowledges and agrees that it is a condition of Tenant's right to
conduct any inspection or audit pursuant to the foregoing, that Tenant prior to
commencement of such inspection or audit shall execute a confidentiality
agreement whereby Tenant agrees to keep confidential and not disclose to any
other party the results of any such inspection or audit or any action taken by
Landlord in response thereto.

     4.      USE OF THE PREMISES.

             A.     RESERVED AREAS. This Lease does not give Tenant any right to
use, and Landlord hereby excludes and reserves for its sole and exclusive use,
the following areas in and about the Premises: janitor closets, stairways and
stairwells (except the internal stairway within the Premises connecting the
eighteenth (18th) and nineteenth (19th) floors, and except that Tenant shall be
permitted to use the Building stairwells between floors of the Premises if
Tenant installs, at Tenant's expense and with Landlord's prior approval and
subject to compliance with all applicable laws, a security access system to the
Premises), fan, mechanical, electrical, telephone and similar rooms (other than
those installed for Tenant's exclusive use); elevator, pipe and other vertical
shafts, flues and ducts; all areas above the acoustical ceiling (subject,
however, to Tenant's removal of ceiling tiles and exposure of the ceiling, which
may be done only with Landlord's prior approval, which will not be unreasonably
withheld, and otherwise in strict compliance with the applicable provisions of
this Lease and the Work Letter attached hereto) and below the finished floor
covering installed in the Premises; all other structural or mechanical elements
serving other areas of the Building; and all subterranean, mineral, air, light
and view rights.

             B.     PERMITTED USE. Tenant shall use and occupy the Premises for
any general office purpose and incidental related purposes consistent with the
operation of a first-class office building in Chicago, Illinois.

             C.     COMPLIANCE WITH LAWS. Tenant shall not use or permit the use
of any part of the Premises for any purpose prohibited by law. Tenant shall, at
its sole expense, comply with and conform to all of the requirements of all
governmental authorities having jurisdiction over the Building which relate in
any way to the internal layout or configuration of the Premises or Tenant's
particular use and occupancy of the Premises throughout the entire Term of this
Lease. Landlord shall operate the Building in compliance with all applicable
laws and requirements of all governmental authorities having jurisdiction over
the Building.

             D.     HAZARDOUS MATERIALS. Tenant agrees that it will not use,
handle, generate, treat, store or dispose of, or permit the handling,
generation, treatment, storage or disposal of any Hazardous Materials in, on,
under, around or above the Premises now or at any future time (except
insubstantial amounts of Hazardous Materials customarily used in connection with

                                       -8-
<Page>

normal office uses, provided such use and storage is in compliance with
applicable laws). The term "Hazardous Materials", when used herein, shall
include, but shall not be limited to, any substances, materials or wastes to the
extent quantities thereof are regulated by the City of Chicago or any other
local governmental authority, the State of Illinois, or the United States of
America because of toxic, flammable, explosive, corrosive, reactive, radioactive
or other properties that may be hazardous to human health or the environment,
including asbestos and including any materials or substances that are listed in
the United States Department of Transportation Hazardous Materials Table, as
amended, 49 C.F.R. 172.101, or in the Comprehensive Environmental Response,
Compensation and Liability Act, as amended, 42 U.S.C. subsections 9601 et seq.,
or the Resource Conservation and Recovery Act, as amended, 42 U.S.C. subsections
6901 et seq., or any other applicable governmental regulation imposing liability
or standards of conduct concerning any hazardous, toxic or dangerous substances,
waste or material, now or hereafter in effect. Tenant's obligations and
liabilities under this paragraph shall survive the expiration of the Term of
this Lease.

     Landlord represents that to the best of its knowledge, without any
independent inquiry or investigation, the Building does not contain any
materials classified as Hazardous Materials, except insubstantial amounts
customarily used in connection with general office building uses.

     5.      POSSESSION.

             A.     Landlord shall tender possession of the Premises to Tenant
upon substantial completion of Landlord's express obligations set forth in the
Work Letter. It is expressly understood and agreed that the Work described in
the Work Letter shall be phased such that the Work on the eighteenth (18th)
floor shall be substantially completed prior to commencement of the Work on the
nineteenth (19th) floor, and that Landlord shall endeavor to substantially
complete the Work on the eighteenth (18th) floor by February 1, 2001 and on the
nineteenth (19th) floor by April 15, 2001, subject to "Tenant Delays" as such
term is defined in the Work Letter and other causes beyond Landlord's reasonable
control. Landlord's obligations shall not be deemed incomplete if only
insubstantial details of construction, decoration or mechanical adjustments
remain to be done.

             B.     The Tenant's taking possession of any portion of the
Premises shall be conclusive evidence that such portion of the Premises was in
good order and satisfactory condition when the Tenant took possession, except
for the Punch List Items (as such term is defined in the Work Letter). No
promise of the Landlord to construct, alter, remodel or improve the Premises or
the Building and no representation by Landlord or its agents respecting the
condition of the Premises or the Building have been made to Tenant or relied
upon by Tenant other than as may be contained in this Lease.

             C.     Tenant is currently occupying that portion of the Premises
comprising the nineteenth (19th) floor of the Building pursuant to a Temporary
Space Agreement between Landlord and Tenant's predecessor-in-interest, DUNC,
LLC, dated as of April 1, 2000 (the "Temporary Space Agreement"), the term of
which Temporary Space Agreement expires on

                                       -9-
<Page>

January 31, 2001. Landlord and Tenant agree that in the event the Commencement
Date of this Lease has not occurred by February 1, 2001, the term of the
Temporary Space Agreement shall be extended until the Commencement Date of this
Lease, and Tenant shall be permitted to continue to occupy the nineteenth (19th)
floor of the Building under all of the terms, covenants and conditions of the
Temporary Space Agreement (including, without limitation, the payment of rent)
until the Commencement Date of this Lease.

     6.      SERVICES.

             A.     LIST OF SERVICES. Landlord shall provide the following
services:

             (i)    Heating and air conditioning when necessary for normal
     comfort in the Premises, from Monday through Friday, during the period from
     8 a.m. to 6 p.m. and on Saturday during the period from 8 a.m. to 1 p.m.,
     excluding holidays. For purposes of this Lease, "holidays" shall not
     include Martin Luther King Day, Presidents' Day or Veterans Day, but shall
     include all other federal holidays. Tenant will pay for all heating and air
     conditioning requested and furnished prior to or following such hours and
     on Sundays and holidays at rates to be established from time to time by
     Landlord (Landlord's current rate therefor being $100.00 per hour, which
     rate is subject to increase from time to time based on increases in
     Landlord's actual costs in providing such additional service, not to exceed
     5% per annum to the extent such increase is due to an expense within
     Landlord's control, and shall not be subject to start-up charges).
     Landlord's obligations with respect to heating and air conditioning are
     subject to all governmental rules, regulations and guidelines applicable
     thereto. As of the date of this Lease, Landlord's heating and cooling
     standards for the Building comply with ASHRAE Standard 62-1989 (and any
     changes thereto).

             (ii)   City water from the regular Building outlets for drinking,
     lavatory and toilet purposes at all times.

             (iii)  Janitorial services Monday through Friday in and about the
     Premises, in accordance with the cleaning specifications attached hereto as
     Exhibit D.

             (iv)   Window washing of the inside and outside of those windows in
     the Building's perimeter walls which are situated in the Premises at
     intervals to be determined by Landlord, but not less than three (3) times
     per annum.

             (v)    Adequate automatic passenger elevator service at all times.

             (vi)   Freight elevator services subject to scheduling by Landlord
     to be made available to Tenant free of charge during Tenant's initial move
     into each floor of the Premises and at Landlord's standard building charge
     thereafter.

                                      -10-
<Page>

             (vii)  Access to the Premises, twenty-four (24) hours per day,
     seven (7) days per week, except in the event of an emergency and subject to
     Tenant's compliance at all times with Building rules and regulations
     applicable thereto (as described in Section 21 hereof) and in effect from
     time to time including, but not limited to, security measures for access
     after normal business hours.

             (viii) Manned security desk on the ground floor lobby of the
     Building, twenty-four (24) hours a day, seven (7) days a week, subject to
     change in conformance with security measures as are, adopted from time to
     time in comparable first-class office buildings in the Chicago metropolitan
     area.

             Landlord also shall provide adequate electrical service to the
electrical closet for standard building lighting fixtures and for Tenant's
incidental uses. Tenant shall bear the cost of replacement of all lamps, tubes,
ballasts and starters for lighting fixtures. With respect to such standard
building lighting fixtures and incidental uses, adequate electrical service will
be furnished in the Premises by Landlord, provided that (a) the connected
electrical load does not exceed an average of five (5) watts per square foot of
the Premises; (b) the electricity so furnished will be at a nominal 120 volts
and no electrical circuit for the supply of such lighting and incidental use
will have a current capacity exceeding 15 amperes; and (c) such electricity will
be used only for standard building lighting fixtures and equipment and
accessories normal to office usage. If Tenant's requirements for electricity are
in excess of those set forth in the preceding sentence, the Landlord reserves
the right to require Tenant to install the conduit, wiring and other equipment
necessary to supply electricity for such excess lighting and incidental use
requirements at the Tenant's expense by arrangement with Commonwealth Edison
Company or another approved local utility.

             B.     BILLING FOR ELECTRICITY. The Premises shall be separately
metered, and Tenant shall pay for the use of all electrical service to the
Premises (other than the electrical service necessary for Landlord to fulfill
its obligation to provide heating and air conditioning as provided in
Subparagraph 6A(i) hereof). Tenant shall make satisfactory arrangements with the
utility company supplying electricity to the Premises for separate billing.
Tenant shall be billed directly by such utility company and Tenant agrees to pay
each bill promptly in accordance with its terms. In the event that for any
reason Tenant cannot be billed directly, Landlord shall forward each bill
received by it with respect to the Premises to Tenant and Tenant shall pay it
promptly in accordance with its terms.

             C.     INTERRUPTION OF SERVICES. Except for the limited abatement
of Rent upon a fire or casualty described in Section 11, Tenant agrees that
Landlord shall not be liable in damages, by abatement of Rent or otherwise, for
failure to furnish or delay in furnishing any service, or for any diminution in
the quality or quantity thereof, when such failure or delay or diminution is
occasioned, in whole or in part, by repairs, renewals, or improvements, by any
strike, lockout or other labor trouble, by inability to secure electricity, gas
or other fuel, or water, at the Building after reasonable effort so to do, by
any accident or casualty whatsoever, by act or default of Tenant or other
parties, or by any cause beyond Landlord's reasonable control. Such

                                      -11-
<Page>

failures or delays or diminution shall never be deemed to constitute an eviction
or disturbance of Tenant's use or possession of the Premises or relieve Tenant
from paying Rent or performing any of its obligations under this Lease. Landlord
shall be diligent in its efforts to cure any such interruption of service.
Notwithstanding the foregoing, in the event that any such interruption in the
furnishing of any of the foregoing services in accordance with the standards and
otherwise pursuant to this Section 6C which was within the reasonable control of
Landlord to prevent continues beyond twenty-four (24) hours after written notice
to Landlord and materially and adversely affects Tenant's ability to conduct its
business in the Premises, or any portion thereof, and on account thereof Tenant
ceases doing business in the Premises, or such portion thereof, Base Rent and
Additional Rent pursuant to Section 3 shall equitably abate from and after the
date of such interference for so long as and to the extent Tenant's ability to
conduct its business in the Premises or such portion thereof is so affected.

             D.     CHARGES FOR SERVICES. Charges for any additional service
for which Tenant is required to pay, from time to time hereunder, including but
not limited to after hours hoisting services (but excluding any hoisting during
Tenant's initial move-in, as set forth in Paragraph 6.A.(vi) above) or after
hours heating or air conditioning shall be due and payable at the same time as
the installment of Rent with which they are billed, or if billed separately,
shall be due and payable within thirty (30) days after such billing. If Tenant
shall fail to make payment for any such additional services, Landlord may, with
twenty-four (24) hours' prior notice to Tenant, discontinue any or all of such
additional services and such discontinuance shall not be deemed to constitute an
eviction or disturbance of Tenant's use and possession of the Premises or
relieve Tenant from paying Rent or performing any of its other obligations under
this Lease.

             E.     ENERGY CONSERVATION.   Notwithstanding anything to the
contrary in this Section 6 or elsewhere in this Lease, Landlord shall have the
right to institute such policies, programs and measures as may be necessary or
desirable, in Landlord's reasonable discretion, for the conservation and/or
preservation of energy or energy related services, or as may be required to
comply with any applicable codes, rules and regulations, whether mandatory or
voluntary, so long as such policies and programs do not materially and adversely
impact Tenant's normal business operations and are enforced in the Building in a
non-discriminatory manner.

     7.      REPAIRS.

             Subject to the terms of Section 11 hereof, Tenant will, at Tenant's
own expense, keep the Premises in good order, repair and condition at all times
during the Term, and Tenant shall promptly and adequately repair all damage to
the Premises and replace or repair all damaged or broken fixtures and
appurtenances, under the supervision and subject to the approval of the Landlord
(which approval shall not unreasonably be withheld, conditioned or delayed), and
within any reasonable period of time specified by the Landlord. If Tenant does
not do so, Landlord may, upon prior reasonable notice (except no notice shall be
necessary in an emergency) but need not, make such repairs and replacements, and
Tenant shall pay Landlord the cost thereof, including a percentage (not to
exceed 10%) of the costs thereof sufficient to reimburse Landlord for all
overhead, general conditions, fees and other costs or expenses arising

                                      -12-
<Page>

from Landlord's involvement with such repairs and replacements, within ten (10)
days of being billed for same. Landlord may, but shall not be required to, enter
the Premises at all reasonable times and with prior reasonable notice (which
notice may be verbal, and except that no notice shall be required in the event
of an emergency) to make such repairs, alterations, improvements and additions
to the Premises or to the Building or to any equipment located in the Building
as Landlord shall desire or deem necessary or as Landlord may be required to do
by governmental authority or court order or decree. Landlord agrees to use
reasonable efforts not to interfere with the conduct by Tenant of its business
in the Premises during ordinary business hours in connection with any such work
performed by Landlord.

             Landlord shall, at Landlord's expense (subject to inclusion of such
expenses in Operating Expenses to the extent permitted by Section 3 hereof),
keep in good order, repair and condition (including the replacement) consistent
with a Class "A" office building in downtown Chicago and maintain in compliance
with all applicable laws at all times during the Term, all structural elements
of the Building, including floor and ceiling slabs, the exterior walls and
windows, the roof, common Building mechanical, plumbing, electrical and HVAC
systems, the elevators, the washrooms, the lobby of the Building and all other
common areas of the Building to the extent such systems or common areas service
or are of benefit to the Premises. Landlord represents that, to the best of its
knowledge, without any independent inquiry or investigation, all common Building
mechanical, plumbing, electrical and HVAC systems serving the Premises are in
good working order and repair as of the date of this Lease.

     8.      ADDITIONS AND ALTERATIONS.

             Tenant shall not, without the prior written consent of Landlord
(which consent shall not unreasonably be withheld, delayed or conditioned, so
long as the structural parts of the Building or Building systems are not
involved), make any alterations, improvements or additions to the Premises.
Landlord's refusal to give said consent shall be conclusive. If Landlord
consents to said alterations, improvements or additions, it may impose such
reasonable conditions with respect thereto as Landlord deems appropriate,
including, without limitation, requiring Tenant to furnish Landlord with
security for the payment of all costs to be incurred in connection with such
work, insurance against liabilities which may arise out of such work, plans and
specifications plus permits necessary for such work and "as-built" drawings or
an accurately marked record set of drawings showing the actual location of said
alterations, improvements and additions. The work necessary to make any
alterations, improvements or additions to the Premises shall be done at Tenant's
expense by employees of, or contractors hired by, Landlord except to the extent
Landlord gives its prior written consent to Tenant's hiring its own contractors
(which consent shall not be unreasonably withheld, delayed or conditioned,
except that Landlord may arbitrarily withhold consent in cases involving
Building systems such as plumbing, HVAC and electrical), and except that Tenant
shall have the right to hire its own contractors in connection with the Tenant
Improvement Work described in Section 30 hereof, subject to Landlord's approval
of said contractors. Tenant shall promptly pay to Landlord or the Tenant's
contractors, as the case may be, when due, the cost of all such work and of all
decorating required by reason thereof. Tenant shall also pay to Landlord a
percentage of the so-called "hard" costs of such work (such

                                      -13-
<Page>

percentage to be established on a uniform basis for the Building and shall not
exceed 5%) sufficient to reimburse Landlord for all overhead, general
conditions, fees and other costs and expenses arising from Landlord's
involvement with such work forthwith upon being billed for the same; provided,
however, that Landlord shall not charge such a percentage in connection with the
Tenant Improvement Work described in Section 30 hereof. Upon completion of such
work Tenant shall deliver to Landlord, if payment is made directly to
contractors, evidence of payment, contractors' affidavits and full and final
waivers of all liens for labor, services or materials all in form reasonably
satisfactory to Landlord. Tenant shall defend and hold Landlord and the Land and
Building harmless from all costs, damages, liens and expenses related to such
work. All work done by Tenant or its contractors pursuant to Section 7 or 8
shall be done in a first-class workmanlike manner using only good grades of
materials and shall comply with all insurance requirements and all applicable
laws and ordinances and rules and regulations of governmental departments or
agencies. Notwithstanding anything herein to the contrary, Landlord's consent
shall not be required for work which (i) does not affect the structural parts of
the Building or the Building systems, (ii) does not involve installation of any
conduit or cabling in the Building, and (iii) does not (on a "per project"
basis) exceed $20,000.00 in any twelve (12) month period, so long as Tenant
employs union contractors to perform such work and provided such work is
scheduled in advance with Landlord.

     Subject to the terms and conditions hereinafter set forth, Tenant shall be
permitted to install computer connections and information pathways ("Network
Connections") in the Premises. The initial cabling, recabling, installation,
removal, connection, reconnection or disconnection of any such Network
Connections shall be performed as part of the Work described in the Work Letter,
and shall be subject to Landlord's approval as more particularly set forth
therein. Any cabling, recabling, installation, removal, repair, expansion,
connection, reconnection or disconnection of any such Network Connections after
such initial installation shall be performed strictly in accordance with this
Section 8, except that Landlord's prior consent shall not be required in
connection therewith provided: (i) Tenant shall notify Landlord in writing
within twenty-four (24) hours following completion (or as soon thereafter as
practicable) of any such cabling, recabling, installation, removal, repair,
expansion, connection, reconnection or disconnection of any such Network
Connections; (ii) Landlord shall thereafter have the right to enter the Premises
to inspect such cabling, recabling, installation, removal, connection, repair,
expansion, reconnection or disconnection of any such Network Connections at any
time within forty-eight (48) hours following such notice, subject to extensions
for any delay on the part of Tenant, to determine if any Building systems have
been altered, disturbed or otherwise negatively affected; (iii) all piping and
telephone riser work in connection with any such Network Connections shall be
performed by union certified personnel; and (iv) all such Network Connections
shall be installed and maintained so as to not interfere with other systems or
services located in the Building or used or maintained by Landlord or any other
tenant.

     9.      COVENANT AGAINST LIENS.

             Tenant has no authority or power to cause or permit any lien or
encumbrance of any kind whatsoever, whether created by act of Tenant, operation
of law or otherwise, to attach

                                      -14-
<Page>

to or be placed upon Landlord's title or interest in the Land, Building or
Premises, and any and all liens and encumbrances created by Tenant shall attach
to Tenant's interest only. Tenant covenants and agrees not to suffer or permit
any lien of mechanics or materialmen or others to be placed against the Land,
Building or the Premises with respect to work or services claimed to have been
performed for or materials claimed to have been furnished to Tenant or the
Premises, and, in case of any such lien attaching, or claim thereof being
asserted, Tenant covenants and agrees to cause it to be immediately released and
removed of record or, if Tenant desires to contest such lien, Tenant shall
provide Landlord with a title insurance indemnity or bond. In the event that
such lien is not released and removed or insured or bonded over within ten (10)
days following notice thereof from Landlord, Landlord, at its sole option, may
take all action necessary to release and remove such lien (without any duty to
investigate the validity thereof) and Tenant shall promptly upon notice
reimburse Landlord for all actual, out-of-pocket sums, costs and expenses
(including reasonable attorney's fees) incurred by Landlord in connection with
such lien.

     10.     INSURANCE.

             A.     WAIVER OF SUBROGATION. Landlord and Tenant each hereby waive
any and every claim for recovery from the other for any and all loss of or
damage to the Building or Premises or to the contents thereof, which loss or
damage is covered by valid and collectible physical damage insurance policies,
or which would be covered if insurance required hereunder were in effect.
Inasmuch as this mutual waiver will preclude the assignment of any such claim by
subrogation (or otherwise) to an insurance company (or any other person),
Landlord and Tenant each agree to give to each insurance company which has
issued, or in the future may issue, to it policies of physical damage insurance,
written notice of the terms of this mutual waiver, and to have said insurance
policies properly endorsed, if necessary, to prevent the invalidation of said
insurance coverage by reason of said waiver.

             B.     COVERAGE. Tenant shall purchase and maintain insurance
during the entire Term for the benefit of Tenant and Landlord (as their interest
may appear) with terms, coverages and in companies reasonably satisfactory to
Landlord, and with such increases in limits as Landlord may from time to time
reasonably request, but initially Tenant shall maintain the following coverages
in the following amounts:

             (i)    Commercial General Liability Insurance naming Tenant,
     Landlord, Landlord's mortgagee and Landlord's management agent covering any
     liability for bodily injury, personal injury and property damage arising
     out of Tenant's operations, assumed liabilities or use of the Premises, for
     limits of liability not less than:

                    Bodily Injury Liability        $3,000,000 each occurrence
                                                   $3,000,000 annual aggregate

                    Personal Injury Liability      $3,000,000 annual aggregate

                                      -15-
<Page>

                    Property Damage Liability      $1,000,000 each occurrence
                                                   $1,000,000 annual aggregate

             (ii)   Physical Damage Insurance covering all office furniture,
     trade fixtures, office equipment, merchandise and all other items of
     Tenant's property on the Premises. Such insurance shall be written on an
     "all risks" of physical loss or damage basis, for the full replacement cost
     value of the covered items and in amounts that meet any coinsurance clause
     of the policies of insurance.

             (iii)  "Dram-Shop" Insurance or Host Liquor Liability Insurance or
     Innkeepers Liability Insurance naming Tenant, Landlord and Landlord's
     management agent covering any liability that might arise from the sale,
     provision or use of alcoholic beverages by Tenant on the Premises in an
     amount reasonably satisfactory to Landlord from time to time in light of
     statutory limits.

Tenant shall, prior to the commencement of the Term, furnish to Landlord
certificates evidencing such coverage, which certificates shall state that such
insurance coverage may not be changed or canceled without at least ten days
prior written notice to Landlord and Tenant.

             C.     AVOID ACTION INCREASING RATES. Tenant shall comply with all
applicable laws and ordinances, all orders and decrees of court and all
requirements of other governmental authorities, and shall not, directly or
indirectly, make any use of the Premises which may thereby be prohibited or be
dangerous to person or property or which may jeopardize any insurance coverage
or may increase the cost of insurance or require additional insurance coverage.
If by reason of the failure of Tenant to comply with the provisions of this
Section 10C, any insurance premium is increased, Tenant shall make immediate
payment of the increased insurance premium upon demand by Landlord or if
insurance coverage is jeopardized, Landlord shall have the option to terminate
this Lease by written notice to Tenant.

             D.     LANDLORD'S INSURANCE. Landlord shall insure the Building on
an "all risks" of physical loss or damage basis, in an amount equivalent to the
full replacement cost of the Building, and shall maintain commercial general
liability insurance as is customarily maintained by landlords of first class
office buildings in downtown Chicago, Illinois. These insurance provisions shall
in no way limit or modify Tenant's obligations under the provisions of this
Lease. All insurance premiums on such policies and the deductible portion of any
claims thereunder shall be included in Operating Expenses.

     11.     FIRE OR CASUALTY.

             A.     Section 7 hereof notwithstanding, if the Premises or the
Building (including machinery or equipment used in its operation) shall be
damaged by fire or other casualty and if such damage does not render all or a
substantial portion of the Premises or Building untenantable, then Landlord
shall repair and restore the same with reasonable promptness, subject to
reasonable delays for insurance adjustments and delays caused by matters

                                      -16-
<Page>

beyond Landlord's reasonable control. If any such damage is uninsured and not
covered by customary fire and extended coverage insurance, Landlord shall have
the right to terminate this Lease as of the date of such damage (with
appropriate prorations of Rent being made for Tenant's possession subsequent to
the date of such damage of those tenantable portions of the Premises) upon
giving written notice to the Tenant at any time within ninety (90) days after
the date of such damage. If any such damage renders all or a substantial portion
of the Premises or the Building untenantable, Landlord shall, within forty-five
(45) days after the occurrence of such damage and in good faith, estimate the
length of time that will be required to substantially complete the repair and
restoration of such damage and shall by notice advise Tenant of such estimate.
If it is so estimated that the amount of time required to substantially complete
such repair and restoration will exceed two hundred seventy (270) days with
respect to damage to the Building (or one hundred eighty (180) days with respect
to damage to the Premises) from the date such damage occurred, then either
Landlord or Tenant shall have the right to terminate this Lease as of the date
of such damage upon giving notice to the other at any time within twenty (20)
days after Landlord gives Tenant the notice containing said estimate (it being
understood that Landlord may, if it elects to do so, also give such notice of
termination together with the notice containing said estimate). Landlord shall
have no liability to Tenant, and Tenant shall not be entitled to terminate this
Lease, by virtue of any delays in completion of such repairs and restoration;
provided, however, that Rent shall abate on those portions of the Premises as
are, from time to time, untenantable as a result of such damage. Notwithstanding
the foregoing, in the event Landlord has promptly commenced and is diligently
proceeding in good faith to complete the work required of it hereunder but is
unable to substantially complete such work within the time period estimated by
Landlord, and if Landlord shall not have substantially completed such work
within an additional sixty (60) day period (plus such additional time as may be
required due to strikes, acts of God, shortages of labor or materials or other
reasons beyond Landlord's reasonable control), Tenant shall upon expiration of
such additional sixty (60) day period (as it may be extended, as aforesaid) have
the right to terminate this Lease upon delivery of written notice to Landlord of
such termination on or before the earlier of (a) the date of substantial
completion of such work or (b) fifteen (15) days following expiration of such
sixty-day period (as it may be extended, as aforesaid). If any damage by fire or
other casualty occurs within one (1) year of the Termination Date of this Lease
and renders the Premises unusable for Tenant's particular business use, and as a
result thereof Tenant ceases to conduct business in the Premises, Tenant shall
also have the right to terminate this Lease as of the date of such damage upon
giving written notice to Landlord at any time within forty-five (45) days after
the date of such damage.

             B.     Landlord shall repair or restore any portion of the
alterations, additions or improvements in the Premises or the decorations
thereto to the extent that such alterations, additions, improvements and
decorations were provided by Landlord at the beginning of the Term or
specifically approved of by Landlord during the Term as provided in Sections 5
and 8. Landlord shall have no further obligation pursuant to this Lease to
repair or restore any alterations, additions or improvements in the Premises or
the decorations thereto. If Tenant desires any other or additional repairs or
restoration, the same shall be done at Tenant's sole cost and expense subject to
all of the provisions of Sections 7 and 8 hereof (including, but not limited to,
the requirements for Landlord's consent thereto). Tenant acknowledges that
Landlord shall

                                      -17-
<Page>

be entitled to the full proceeds of any insurance coverage, whether carried by
Landlord or Tenant, for damage to alterations, additions, improvements or
decorations which would become Landlord's property upon the termination of this
Lease.

     12.     WAIVER OF CLAIMS - INDEMNIFICATION.

             To the extent not prohibited by law and except for the negligence
or willful misconduct of Landlord, its agents or employees (but subject in all
events to the provisions of Section 10 hereof), Landlord and Landlord's members,
managers, partners, affiliates, officers, agents, servants and employees shall
not be liable for any damage either to person, property or business or resulting
from the loss of use thereof sustained by Tenant or by other persons due to the
Building or any part thereof or any appurtenances thereof becoming out of
repair, or due to the happening or any accident or event in or about the
Building, including the Premises, or due to any act or neglect of any tenant or
occupant of the Building or of any other person. This provision shall apply
particularly, but not exclusively, to damage caused by gas, electricity, snow,
ice, frost, steam, sewage, sewer gas or odors, fire, water or by the bursting or
leaking of pipes, faucets, sprinklers, plumbing fixtures and windows, and,
except as otherwise expressly provided herein or prohibited by law (but subject
in all events to the provisions of Section 10 hereof), shall apply without
distinction as the person whose act or neglect was responsible for the damage
and whether the damage was due to any of the causes specifically enumerated
above or to some other cause of an entirely different kind. Tenant further
agrees that all personal property upon the Premises, or upon loading docks,
receiving and holding areas, or freight elevators of the Building, shall be at
the risk of Tenant only, and that Landlord shall not be liable for any loss or
damage thereto or theft thereof. Without limitation of any other provisions
hereof, Tenant agrees to defend, protect, indemnify and save harmless Landlord
and Landlord's members, managers, partners, affiliates, officers, agents,
servants and employees from and against all liability to third parties arising
out of the use of the Premises or acts of Tenant or its servants, agents,
employees, contractors, suppliers, workers or invitees, but only to the extent
that such liability is not covered by the proceeds of insurance required to be
maintained by Landlord pursuant to Section 10 hereof. Except to the extent
caused by the negligence or willful misconduct of Tenant, its officers, agents,
servants and employees, Landlord agrees to defend, protect, indemnify and save
harmless Tenant and its partners, affiliates, officers, agents, servants and
employees from and against all liability to third parties arising out of or in
connection with Landlord's ownership and operation of the Building or Landlord's
activities in the Building or arising from any act of Landlord or its servants,
agents, employees, contractors, suppliers, workers or invitees, but only to the
extent that such liability is not covered by the proceeds of insurance required
to be maintained by Tenant pursuant to Section 10 hereof (whether or not such
insurance is in fact so maintained by Tenant).

     13.     NONWAIVER.

             No waiver of any provision of this Lease shall be implied by any
failure of Landlord or Tenant to enforce any remedy on account of the violation
of such provisions, even if such violation be continued or repeated
subsequently, and no express waiver shall affect any

                                      -18-
<Page>

provision other than the one specified in such waiver and that one only for the
time and in the manner specifically stated. No receipt of monies by Landlord
from Tenant after the termination of this Lease shall in any way alter the
length of the Term or of Tenant's right of possession hereunder or after the
giving of any notice shall reinstate, continue or extend the Term or affect any
notice given Tenant prior to the receipt of such monies, it being agreed that
after the service of notice or the commencement of a suit or after final
judgment for possession of the Premises, Landlord may receive and collect any
Rent due, and the payment of said Rent shall not waive or affect said notice,
suit or judgment.

     14.     CONDEMNATION.

             A.     In the event all or substantially all of the Building or the
Premises is taken or condemned by eminent domain or by any conveyance in lieu
thereof (such taking, condemnation or conveyance in lieu thereof being
hereinafter referred to as "condemnation"), the Term shall cease and this Lease
shall terminate on the earlier of the date the condemning authority takes
possession or the date title vests in the condemning authority. In the event any
portion of the Building shall be taken by condemnation (whether or not such
taking includes any portion of the Premises), which taking, in Landlord's
reasonable judgment, is such that the Building cannot be restored in an
economically feasible manner for use substantially as originally designed, then
Landlord shall have the right, at Landlord's option, to terminate this Lease,
effective as of the date specified by Landlord in a written notice of
termination from Landlord to Tenant, which date shall be no earlier than one
hundred twenty (120) days following the date of Landlord's notice, unless the
condemning authority shall take possession on an earlier date, in which event
the date of possession shall be the date of termination. In the event that a
portion, but less than substantially all, of the Premises shall be taken by
condemnation, then this Lease shall be terminated as of the date of such
condemnation as to the portion of the Premises so taken, and, unless Landlord
exercises its option to terminate this Lease set forth in this Section 14, this
Lease shall remain in full force and effect as to the remainder of the Premises.
Notwithstanding the foregoing, in the event any such taking includes a portion
of the Premises which, in Tenant's reasonable judgment, is material to Tenant's
use and enjoyment of the Premises, Tenant shall have the right, at Tenant's
option, to terminate this Lease, effective as of the date specified by Tenant in
a written notice of termination from Tenant to Landlord (which specified date
shall be no earlier than the earlier of the date the condemning authority takes
possession or the date title vests in the condemning authority). In the event of
termination of this Lease pursuant to the provisions of this Section 14, the
Rent shall be apportioned as of such date of termination (based on the remaining
square footage of the Premises) provided, however, that those provisions of this
Lease which are designated to cover matters of termination and the period
thereafter shall survive the termination hereof.

             B.     All compensation awarded or paid upon a condemnation of any
portion of the Building shall belong to and be the property of Landlord without
participation by Tenant. Nothing herein shall be construed, however, to preclude
Tenant from prosecuting any claim directly against the condemning authority for
loss of business, loss of good will, moving expenses, damage to, and cost of
removal of, trade fixtures, furniture and other personal property

                                      -19-

belonging to Tenant; provided, however, that Tenant shall make no claim which
shall diminish or adversely affect any award claimed or received by Landlord.

             C.     If any portion of the Land other than the Building is taken
 by condemnation or if the temporary use or occupancy of all or any part of the
 Premises shall be taken by condemnation during the Term, this Lease shall be
 and remain unaffected by such condemnation, and Tenant shall continue to pay in
 full the Rent payable hereunder. In the event of any such temporary taking for
 use or occupancy of all or any part of the Premises, Tenant shall be entitled
 to appear, claim, prove and receive the portion of the award for such taking
 that represents compensation for use or occupancy of the Premises during the
 Term and Landlord shall be entitled to appear, claim, prove and receive the
 portion of the award that represents the cost of restoration of the Premises
 and the use or occupancy of the Premises after the end of the Term hereof. In
 any event of any such condemnation of any portion of the Land other than the
 Building, Landlord shall be entitled to appear, claim, prove and receive all of
 that award.

     15.     ASSIGNMENT AND SUBLETTING.

             A.     Subject to any provisions of this Section 15 to the
contrary, Tenant shall not, without the prior written consent of Landlord (which
consent shall not unreasonably be withheld, delayed or conditioned as set forth
in Section 15C below) (i) assign, convey or mortgage this Lease or any interest
hereunder; (ii) permit to occur or permit to exist any assignment of this Lease,
or any lien upon Tenant's interest, voluntarily or by operation of law; (iii)
sublet the Premises or any part thereof; or (iv) permit the use of the Premises
by any parties other than Tenant and its employees and its contractors who are
providing services to Tenant (and not to other parties) in the Premises. Any
such action on the part of Tenant shall be void and of no effect. There shall be
no partial assignment of Tenant's interest in this Lease. The term "sublease"
and all words derived therefrom, as used in this Section 15, shall include any
subsequent sublease or assignment of such sublease and any other interest
arising under such sublease. Landlord's consent to any assignment, subletting or
transfer or Landlord's election to accept any assignee, subtenant or transferee
as the tenant hereunder and to collect rent from such assignee, subtenant or
transferee shall not release Tenant or any subsequent tenant from any covenant
or obligation under this Lease. Landlord's consent to any assignment, subletting
or transfer shall not constitute a waiver of Landlord's right to withhold its
consent to any future assignment, subletting, or transfer. Landlord may
condition its consent upon execution by the subtenant or assignee of an
instrument confirming such restrictions on further subleasing or assignment and
joining in the waivers and indemnities made by Tenant hereunder.

             B.     If Tenant desires the consent of Landlord to an assignment
or subletting, Tenant shall submit to Landlord at least thirty (30) days prior
to the proposed effective date of the assignment or sublease a written notice
which includes:

             1.     all documentation then available related to the proposed
     sublease or assignment (copies of final executed documentation to be
     supplied on or before the effective date); and

                                      -20-
<Page>

             2.     sufficient information to permit Landlord to determine the
     identity and character of the proposed subtenant or assignee and the
     financial condition of the proposed assignee.

             C.     If Landlord does not terminate this Lease, in whole or in
part, pursuant to Section 15D, Landlord shall not unreasonably withhold, delay
or condition its consent to such assignment or subletting; provided, however, it
shall be reasonable for Landlord to withhold its consent if:

             1.     in the reasonable judgment of Landlord the subtenant or
     assignee is of a character or engaged in a business or attracts a volume,
     frequency or type of employee or visitor which is not in keeping with the
     standards maintained by Landlord in the Building or that will impose an
     excessive demand on or use of the facilities or services of the Building;

             2.     in the reasonable judgment of Landlord the purpose for which
     the subtenant or assignee intends to use the subleased space is in
     violation of the terms of this Lease or the lease of any other tenant in
     the Building which prohibits such use;

             3.     the subtenant or assignee is a governmental authority or
     agency or an organization or persons enjoying sovereign or diplomatic
     immunity; or

             4.     such assignment or subletting would cause a default under
     another lease in the Building or under any ground lease, deed of trust,
     mortgage, restrictive covenant, easement or other encumbrance affecting the
     Land.

             D.     In addition to withholding its consent (in those cases in
which Landlord's consent is required), Landlord shall have the right to
terminate this Lease as to that portion of the Premises which Tenant seeks to
assign or sublet, whether by requesting Landlord's consent thereto or otherwise.
Landlord may exercise such right to terminate by giving written notice to Tenant
at any time prior to Landlord's written consent to such assignment or sublease.
In the event Landlord shall exercise its termination right, Tenant shall have
the right to withdraw its notice of intent to assign or sublease, and thus
nullify Landlord's termination exercise, by providing notice to Landlord within
ten (10) days of Landlord's exercise of its termination right. In the event that
Landlord exercises such right to terminate (which right is not nullified as set
forth in the preceding sentence), Landlord shall be entitled to recover
possession of and Tenant shall surrender such portion of the Premises on the
later of (i) the proposed date for possession by such assignee or subtenant, or
(ii) ninety (90) days after the date of Landlord's notice of termination to
Tenant.

             E.     In the event that Landlord consents to any assignment or
sublease of any portion of the Premises, as a condition of Landlord's consent,
if Landlord so elects to consent, Tenant shall pay to Landlord the amounts
described in Paragraph G below plus fifty percent

                                      -21-
<Page>

(50%) of all profit (after deducting therefrom any broker commissions, legal
fees, tenant improvement costs and all other direct and reasonable costs
incurred by Tenant in connection with such assignment or subletting) derived by
Tenant from such assignment or sublease. Tenant shall furnish Landlord with a
sworn statement, certified by an independent certified public accountant,
setting forth in detail the computation of profit (which computation shall be
based upon an appropriate system of accounts and accounting practices
consistently applied), and Landlord, or its representatives, shall have access
to the books, records and papers of Tenant in relation thereto, and may make
copies thereof. Any rent in excess of that paid by Tenant hereunder for the
Premises so assigned or sublet realized by reason of such assignment or sublease
shall be deemed an item of such profit. If a part of the consideration for such
assignment or sublease shall be payable other than in cash, the payment to
Landlord shall be payable in accordance with the foregoing percentage of the
cash and other non-cash considerations in such form as is satisfactory to
Landlord. Such percentage of Tenant's profits shall be paid to Landlord promptly
by Tenant upon Tenant's receipt from time to time of periodic payments from such
assignee or subtenant or at such other time as Tenant shall realize its profits
from such assignment or sublease. If such sublease or assignment is part of a
larger transaction in which other assets of Tenant are being transferred, the
consideration for the assignment or sublease shall be the fair market value of
such assignment or the fair market rental for such sublease, as reasonably
determined by Landlord.

             F.     [Intentionally Omitted.]

             G.     Tenant shall pay to Landlord all reasonable attorney's fees
and other reasonable costs and expenses incurred by Landlord in reviewing the
documentation and determining whether to consent to any proposed sublease or
assignment, regardless of whether Landlord consents or does not consent;
provided, however, that the foregoing amounts shall not exceed $2,500.00 in the
case of any routine sublease or assignment not requiring extended attorney
review.

             H.     Notwithstanding anything in this Section 15 to the contrary,
Tenant shall have the right, upon ten (10) days' prior written notice to
Landlord but without obtaining Landlord's prior consent and without payment to
Landlord of any profit, (a) to sublet all or part of the Premises to any
subsidiary, parent or affiliate of Tenant or any related corporation or other
entity which controls Tenant, is controlled by Tenant or is under common control
with Tenant; or (b) to assign this Lease to a successor corporation or other
entity into which or with which Tenant is merged or consolidated or which
acquired substantially all of Tenant's assets and property; provided that (i)
such successor corporation or entity assumes all of the obligations and
liabilities of Tenant and shall have net worth at least equal to the net worth
of Tenant immediately prior to such assignment or sublease, as determined by an
appropriate system of accounts and accounting practices consistently applied,
and (ii) Tenant provides in its notice to Landlord the information required in
this Section 15. For the purpose hereof "control" shall mean ownership of not
less than 50% of all the voting stock or legal and equitable interest in such
corporation or entity.

                                      -22-
<Page>

     16.     SURRENDER OF POSSESSION.

             All alterations, improvements and additions to the Premises,
whether temporary or permanent in character, made or paid for by Landlord or
Tenant, shall without compensation to Tenant become Landlord's property at the
termination of this Lease by lapse of time or otherwise and shall, unless
Landlord requests their removal as hereinafter set forth, be relinquished to
Landlord in good condition, ordinary wear and tear excepted.

             Upon the expiration of the Term or upon the termination of Tenant's
right of possession, whether by lapse of time or at the option of Landlord as
herein provided, Tenant shall forthwith surrender the Premises to Landlord in
good order, repair and condition, ordinary wear and tear and damage by fire or
other casualty excepted, and shall, if Landlord so requires, remove those
alterations, improvements and additions to the Premises including built-in
furniture or shelves and all other attached items which Landlord shall request
Tenant remove and restore the Premises to the condition existing at the
beginning of the Term, ordinary wear and tear and damage by fire or other
casualty excepted; provided, however, that Tenant shall not be obligated to
remove building standard items or items, or alterations, improvements or
additions as to which Landlord has waived in writing upon the written request of
Tenant for such waiver, at the time of approval of the plans therefor pursuant
to Section 8 hereof, its right to require their removal. Prior to the
termination of the Term or of Tenant's right of possession Tenant shall remove
its office furniture, trade fixtures, office equipment and all other items of
Tenant's movable property on the Premises. Tenant shall pay to Landlord upon
demand the cost of repairing any damage to the Premises and to the Building
caused by any removal. If Tenant shall fail or refuse to remove any property
which it is required to remove from the Premises, Tenant shall be conclusively
presumed to have abandoned the same, and title thereto shall thereupon pass to
Landlord without any cost either by set-off, credit, allowance or otherwise, and
Landlord may at its option accept the title to such property or at Tenant's
expense may (i) remove the same or any part in any manner that Landlord shall
choose, repairing any damage to the Premises caused by such removal, and (ii)
store, destroy or otherwise dispose of the same without incurring liability to
Tenant or any other person.

     17.     HOLDING OVER.

             Tenant shall pay to Landlord an amount as Rent equal to 200% of
one-twelfth of the Base Rent and 200% of one-twelfth of the Additional Rent
payable by Tenant during the previous Calendar Year herein provided during each
month or portion thereof for which Tenant shall retain possession of the
Premises or any part thereof after the expiration or termination of the Term or
of Tenant's right of possession, whether by lapse of time or otherwise (except
the first sixty (60) days of any such holding over shall be at 150% of the Base
Rent and 150% of the Additional Rent), and also shall pay all direct damages
sustained by Landlord on account thereof. At the option of Landlord, expressed
in a written notice to Tenant and not otherwise, any such holding over for a
period of more than sixty (60) days shall constitute a renewal of this Lease for
a period of one year at the greater of the fair market rental for the Premises,
as reasonably determined by Landlord, or the Base Rent during the preceding year
and the Additional Rent that

                                      -23-
<Page>

would be applicable for such year if the Term were one year longer. It is
specifically agreed that Tenant shall have no liability for consequential
damages resulting from a retention of possession beyond the expiration of the
Term; provided, however, that if Landlord shall have given to Tenant at least
sixty (60) days advance notice that Landlord has relet the Premises, or portions
thereof, then if Tenant's holdover continues more than sixty (60) days in
duration at any time after delivery of such notice, Landlord's direct damages
shall include, without limitation, compensation for the loss of income on
account of such reletting, together with any damages for which Landlord shall be
liable to third parties (including the party releasing the Premises, or portion
thereof), and reasonable legal fees and litigation costs paid by Landlord, as a
result of Tenant's failure to surrender possession of the Premises. The
provisions of this Section 17 shall not be deemed to limit or constitute a
waiver of any other rights or remedies of Landlord provided herein or at law or
in equity.

     18.     ESTOPPEL CERTIFICATE.

             Tenant agrees that, from time to time upon not less than ten (10)
days' prior request by Landlord, Tenant, or Tenant's duly authorized
representative having knowledge of the following facts, will deliver to Landlord
a statement in writing certifying (i) that this Lease is unmodified and in full
force and effect (or if there have been modifications, a description of such
modifications and that the Lease as modified is in full force and effect); (ii)
the dates to which Rent and other charges have been paid; (iii) that, to the
best of Tenant's knowledge, the Landlord is not in default under any provision
of this Lease, or, if in default, the nature thereof in detail; and (iv) such
further matters as are set forth on the form of estoppel certificate attached
hereto as Exhibit F and made a part hereof, or as may be requested by Landlord,
it being intended that any such statement may be relied upon by any prospective
assignee of any tenant of the Building, any mortgagees or prospective mortgagees
thereof, or any prospective assignee of any mortgagee thereof, or any
prospective and/or subsequent purchaser or transferee of all or a part of
Landlord's interest in the Land and/or Building. Tenant shall execute and
deliver whatever instruments may be required for such purposes, and in the event
Tenant continues to fail so to do within five (5) days after a second demand in
writing, then Landlord shall be authorized as Tenant's agent and
attorney-in-fact to execute such statement on behalf of Tenant.

             Landlord agrees that, from time to time upon not less than fifteen
(15) days' prior request by Tenant (but not more frequently than one time during
the Term, as it may be extended pursuant to Section 32 hereof), Landlord, or
Landlord's duly authorized representative having knowledge of the following
facts, will deliver to Tenant a statement in writing certifying (i) that this
Lease is unmodified and in full force and effect (or if there have been
modifications, a description of such modifications and that the Lease as
modified is in full force and effect); (ii) the dates to which Rent and other
charges have been paid; (iii) that, to the best of Landlord's knowledge, the
Tenant is not in default under any provision of this Lease, or, if in default,
the nature of thereof in detail; and (iv) such further matters as may reasonably
be requested by Tenant.

                                      -24-

     19.     OBLIGATIONS TO MORTGAGEES.

             A.     SUBORDINATION. This Lease is subject and subordinate to all
present and future ground or underlying leases of the Land and to the lien of
any mortgages or trust deeds now and hereafter in force against the Land or
Building and to all renewals, extensions, modifications, consolidation and
replacements thereof, and to all advances made or hereafter to be made upon the
security thereof. Tenant shall at Landlord's request execute such further
instruments or assurances as Landlord may deem necessary to evidence, confirm or
effectuate such subordination of this Lease thereto or, if requested, to make
Tenant's interest in this Lease superior thereto. If any mortgage shall be
foreclosed or property encumbered thereby is transferred in lieu of foreclosure,
or if any ground or underlying lease be terminated, (i) the liability of the
mortgagee or trustee hereunder or purchaser at such foreclosure sale or the
liability of a subsequent owner designated as Landlord under this Lease shall
exist only so long as such trustee, mortgagee, purchaser or owner is the owner
of the Land or Building and such liability shall not continue or survive after
further transfer of ownership; and (ii) upon the request of the mortgagee,
trustee or ground lessor, Tenant will attorn, as Tenant under this Lease, to the
purchaser at any foreclosure sale under any mortgage or the ground lessor, by
executing such instruments as may reasonably be required by the mortgagee,
trustee or ground lessor.

             B.     NOTICE TO LANDLORD AND MORTGAGEE. In the event of any act or
omission by Landlord which would give Tenant the right to damages from Landlord
or the right to terminate this Lease, Tenant will not sue for such damages or
exercise any such right to terminate until (i) it shall have given written
notice of the act or omission to Landlord and to the holder(s) of the
indebtedness or other obligations secured by a mortgage or deed of trust
affecting the Premises or of any ground or underlying lease, if the name and
address of such holder(s) have been furnished to Tenant, and (ii) a reasonable
period of time, in light of the time required to effect a remedy and of the
impact of the act or omission on Tenant's business operations on the Premises,
for remedying the act or omission has elapsed following the giving of the
notice, during which time Landlord and such holder(s), or either of them, their
agents or employees, will be entitled to enter upon the Premises and do therein
whatever may be necessary to remedy the act or omission.

             C.     NON-DISTURBANCE AGREEMENT. Promptly after substantial
completion by Landlord of the Work in the Premises, Landlord shall provide
Tenant with a Non-Disturbance Agreement from Landlord's current mortgage lender
substantially in the form attached hereto as Exhibit I, and the obligations of
Tenant under this Paragraph 19 are contingent upon Tenant's receipt of such
Non-Disturbance Agreement. Landlord further agrees that, to the extent any
future mortgagee or holder(s) of the indebtedness or other obligations secured
by a mortgage or deed of trust affecting the Premises or of any ground or
underlying lease, obtains an interest in the Land or Building and this Lease is
required to become subordinate thereto, as a condition to the effectiveness of
any subordination of this Lease pursuant to Section 19. A above to any future
mortgage, Tenant shall receive a non-disturbance agreement from any such
mortgagee on such mortgagee's then-standard form therefor (and, in the event
such non-disturbance agreement is not

                                      -25-
<Page>

made available to Tenant, Tenant's rights under this Lease in such instance
shall not be subordinated to such mortgage).

     20.     CERTAIN RIGHTS RESERVED BY LANDLORD.

     Landlord shall have the following rights, each of which Landlord may
exercise without notice to Tenant (except as otherwise expressly provided) and
without liability to Tenant for damage or injury to property, person or business
on account of the exercise thereof, and the exercise of any such rights shall
not be deemed to constitute an eviction or disturbance of Tenant's use or
possession of the Premises and shall not give rise to any claim for set-off or
abatement of rent or any other claim (and Landlord agrees to use reasonable
efforts to minimize any interference with the conduct by Tenant of its business
in the Premises in connection with Landlord's exercise of such rights):

             (i)    Upon prior reasonable notice, to change the name or street
     address of the Building, and if such change is voluntary, Landlord agrees
     to replace reasonable quantities of Tenant's stationery, business cards and
     other similar printed material.

             (ii)   To install, affix and maintain any and all signs on the
     exterior or interior of the Building.

             (iii)  To decorate or to make repairs, alterations, additions, or
     improvements, whether structural or otherwise, in and about the Building,
     or any part thereof, and for such purposes to enter upon the Premises, and
     during the continuance of any of said work, to temporarily close doors,
     entryways, public space and corridors in the Building and to interrupt or
     temporarily suspend services or use of facilities, all without affecting
     any of Tenant's obligations hereunder, so long as the Premises are
     reasonably accessible and usable (so long as such entry and work is made
     and performed in accordance with the provisions of Paragraph 7 hereof).
     Except in case of emergency repairs, Landlord will give Tenant reasonable
     advance notice of any contemplated stoppage or entry upon the Premises and
     will use reasonable efforts to avoid unnecessary inconvenience to Tenant by
     reason thereof.

             (iv)   To furnish door keys or magnetic cards for the entry door(s)
     in the Premises at the commencement of the Lease and to retain at all
     times, and to use in appropriate instances, keys to all doors within and
     into the Premises. Tenant agrees to purchase only from Landlord additional
     duplicate keys as required, to change no locks, and not to affix locks on
     doors without the prior written consent of the Landlord (which consent
     shall not unreasonably be withheld, conditioned or delayed).
     Notwithstanding the provisions for Landlord's access to the Premises,
     Tenant relieves and releases the Landlord of all responsibility arising out
     of theft, robbery, pilferage and personal assault, except to the extent
     caused by the gross negligence or willful misconduct of Landlord, its
     agents or employees (but subject in all events to the provisions of Section
     10 hereof). Upon the expiration of the Term or Tenant's right to
     possession, Tenant shall return all

                                      -26-
<Page>

     keys to Landlord and shall disclose to Landlord the combination of any
     safes, cabinets or vaults left in the Premises.

             (v)    To designate and approve all window coverings used in the
     Building.

             (vi)   To approve the weight, size and location of safes, vaults,
     vertical files and other heavy equipment and articles in and about the
     Premises and the Building so as not to exceed the legal live load per
     square foot designated by the structural engineers for the Building, and to
     require all such items and furniture and similar items to be moved into or
     out of the Building and Premises only at such times and in such manner as
     Landlord shall reasonably direct. Tenant shall not install or operate
     machinery or any mechanical devices of a nature not directly related to
     Tenant's ordinary use of the Premises without the prior written consent of
     Landlord (which consent shall not unreasonably be withheld, conditioned or
     delayed). Movements of Tenant's property into or out of the Building or
     Premises and within the Building are entirely at the risk and
     responsibility of Tenant and Landlord reserves the right to require permits
     before allowing any property to be moved into or out of the Building or
     Premises.

             (vii)  To establish controls for the purpose of regulating all
     property and packages, both personal and otherwise, to be moved into or out
     of the Building and Premises and all persons using the Building after
     normal office hours.

             (viii) To regulate delivery and service of supplies and the usage
     of the loading docks, receiving areas and freight elevators.

             (ix)   To show the Premises to prospective tenants at reasonable
     times and upon prior reasonable notice (which notice may be verbal) during
     the last twelve (12) months of the Term and, if vacated or abandoned for a
     period of thirty (30) or more consecutive days, to show the Premises at any
     time and, if this Lease or Tenant's right to possession is terminated
     pursuant to Section 11 hereof, to prepare the Premises for re-occupancy.

             (x)    Upon prior reasonable notice (which notice may be verbal,
     and except that no notice shall be required in the event of an emergency)
     to enter the Premises at any reasonable time to inspect the Premises.

             (xi)  To grant to any person or to reserve unto itself the
     exclusive right to conduct any business or render any service in the
     Building. If Landlord elects to make available to tenants in the Building
     any services or supplies, or arranges a master contract therefor, Tenant
     agrees to obtain its requirements, if any, therefor from Landlord or under
     any such contract, provided that the charges therefor are reasonable.

             (xii)  To close the Building after regular working hours and on
     Saturdays, Sundays and legal holidays subject, however, to Tenant's right
     to admittance at all times to the Premises under such reasonable
     regulations as Landlord may prescribe from time

                                      -27-
<Page>

     to time, which may include, but shall not be limited to, a requirement that
     persons entering or leaving the Building identify themselves to a watchman
     by registration or otherwise and establish their right to enter or leave
     the Building. Such regulations may include, but shall not be limited to,
     the requiring of identification from Tenant's employees, agents, clients,
     customers, invitees, visitors and guests.

     21.     RULES AND REGULATIONS.

             Tenant agrees to observe the rules and regulations for the Building
attached hereto as Exhibit E and made a part hereof. Landlord shall have the
right from time to time to prescribe additional rules and regulations which, in
its reasonable judgment, may be desirable for the use, entry, operation and
management of the Premises and Building, each of which rules and regulations and
any amendments thereto shall become a part of this Lease. Tenant shall comply
with all such rules and regulations; provided, however, that such rules and
regulations shall not contradict or abrogate any right or privilege herein
expressly granted to Tenant. Landlord agrees not to selectively enforce in a
discriminatory manner against Tenant but not other tenants in the Building any
of the rules and regulations described in this Section 21.

     22.     LANDLORD'S REMEDIES.

             If default shall be made in the payment of the Rent or any
installment thereof or in the payment of any other sum required to be paid by
Tenant under this Lease or under the terms of any other agreement between
Landlord and Tenant and such default shall continue for ten (10) days after
written notice to Tenant, or if default shall be made in the observance or
performance of any of the other covenants or conditions in this Lease which
Tenant is required to observe and perform and such default shall continue for
thirty (30) days after written notice to Tenant (or, in the event such default
cannot reasonably be cured within such thirty (30) day period, within such
additional time -- not to exceed a total period of ninety (90) days from the
date of Landlord's notice -- as may be required for Tenant to effect such cure,
so long as Tenant promptly commences to cure such default within such initial
thirty (30) day period and thereafter diligently pursues such cure to
completion), or if a default involves a hazardous condition and is not cured by
Tenant immediately upon written notice to Tenant, or if the interest of Tenant
in this Lease shall be levied on under execution or other legal process, or if
any voluntary petition in bankruptcy or for corporate reorganization or any
similar relief shall be filed by Tenant, or if any involuntary petition in
bankruptcy shall be filed against Tenant under any federal or state bankruptcy
or insolvency act and shall not have been dismissed within ninety (90) days from
the filing thereof, or if a receiver shall be appointed for Tenant or any of the
property of Tenant by any court and such receiver shall not have been dismissed
within ninety (90) days from the date of its appointment, or if Tenant shall
make an assignment for the benefit of creditors, or if Tenant shall admit in
writing Tenant's inability to meet Tenant's debts as they mature, or if Tenant
shall abandon the Premises during the Term (together with the failure to pay
Rent), then Landlord may treat the occurrence of any one or more of the
foregoing events as a breach of this Lease, and thereupon at its option may,
with or without further notice or demand of any kind to Tenant or

                                      -28-
<Page>

any other person, have any one or more of the following described remedies in
addition to all other rights and remedies provided at law or in equity or
elsewhere herein:

             (i)    Landlord may terminate this Lease and the Term created
     hereby, in which event Landlord may forthwith repossess the Premises and be
     entitled to recover forthwith, in addition to any other sums or damages,
     for which Tenant may be liable to Landlord, as damages a sum of money equal
     to the excess of the present value of the Rent provided to be paid by
     Tenant for the balance of the Term over the present value of the fair
     market rent for the Premises, after deduction of all reasonably anticipated
     expenses of reletting, for said period. For the purpose of determining
     present value, Landlord and Tenant agree that the interest rate shall be
     the rate applicable to the then-current yield on obligations of the U.S.
     Treasury having a maturity date on or about the Termination Date. Should
     the present value of the fair market rent for the Premises, after deduction
     of all reasonably anticipated expenses of reletting, for the balance of the
     Term exceed the present value of the Rent provided to be paid by Tenant for
     the balance of the Term, Landlord shall have no obligation to pay to Tenant
     the excess or any part thereof or to credit such excess or any part thereof
     against any other sums or damages for which Tenant may be liable to
     Landlord.

             (ii)   Landlord may terminate Tenant's right of possession and may
     repossess the Premises by forcible entry and detainer suit, by taking
     peaceful possession or otherwise, without terminating this Lease, in which
     event Landlord may, but shall be under no obligation to, relet the same
     (except to the extent required by applicable law) for the account of
     Tenant, for such rent and upon such terms as shall be commercially
     reasonable. For the purpose of such reletting, Landlord is authorized to
     decorate, repair, remodel or alter the Premises. If Landlord shall fail to
     relet the Premises, Tenant shall pay to Landlord as damages a sum equal to
     the amount of the Rent reserved in this Lease for the balance of the Term
     as such Rent shall become due and payable hereunder from time to time
     during the Term. If the Premises are relet and a sufficient sum shall not
     be realized from such reletting after paying all of the costs and expenses
     of all decoration, repairs, remodeling, alterations and additions and the
     expenses of such reletting and of the collection of the rent accruing
     therefrom to satisfy the Rent provided for in this Lease, Tenant shall
     satisfy and pay the same upon demand therefor from time to time. Tenant
     shall not be entitled to any rents received by Landlord in excess of the
     Rent provided for in this Lease. Tenant agrees that Landlord may file suit
     to recover any sums falling due under the terms of this Section 22 from
     time to time and that no suit or recovery of any portion due Landlord
     hereunder shall be any defense to any subsequent action brought for any
     amount not theretofore reduced to judgment in favor of Landlord.

     23.     EXPENSES OF ENFORCEMENT.

             Either party hereto shall pay to the other (the "Prevailing
Party"), upon demand, all reasonable costs, charges and expenses, including the
reasonable fees and out-of-pocket expenses of counsel, agents and others
retained by the Prevailing Party, incurred in successfully enforcing the other
party's obligations hereunder. In the event either party shall be made a party
to any litigation, negotiation or transaction commenced by or against the other
party, and is not at fault, the other party shall pay all costs, charges and
expenses, including the fees and out-of-pocket expenses of counsel, agents and
others retained by such party in connection with such matter.

     24.     COVENANT OF QUIET ENJOYMENT.

             Landlord covenants that Tenant, on paying the Rent, charges for
services and other payments herein reserved and on keeping, observing and
performing all the other terms, covenants, conditions, provisions and agreements
herein contained on the part of Tenant to be kept, observed and performed,
shall, during the Term, peaceably and quietly have, hold and enjoy the Premises
subject to the terms, covenants, conditions, provisions and agreements hereof.

     25.     LETTER OF CREDIT.

             A.     As security for the full and prompt performance by Tenant of
all Tenant's obligations hereunder, Tenant has upon execution of this Lease
provided to Landlord an unconditional irrevocable letter of credit in favor of
Landlord from a bank approved by Landlord, in substantially the form attached
hereto as Exhibit G (the "Letter of Credit"), which shall provide for security
in the amount of $1,800,000.00. Provided Landlord has not theretofore drawn on
the Letter of Credit and provided Tenant is not then in default in the payment
of Rent (beyond the expiration of any applicable cure period) or other sums due
and owing to Landlord under this Lease or then in default under any other
material term, covenant or condition of this Lease, the Letter of Credit shall
be reduced as follows: to sum of $1,542,857.00 at the end of the First (1st)
Lease Year; to the sum of $1,285,714.00 at the end of the Second (2nd) Lease
Year; to the sum of $1,028,571.00 at the end of the Third (3rd) Lease Year; to
the sum of $771,428.00 at the end of the Fourth (4th) Lease Year; to the sum of
$514,285.00 at the end of the Fifth (5th) Lease Year; to the sum of $257,142.00
at the end of the Sixth (6th) Lease Year; and to zero ($-0-) at the end of the
Seventh (7th) Lease Year. Tenant agrees that, in the event of any default by
Tenant under this Lease (after expiration of all applicable notice and cure
periods), Landlord shall have the right to draw down on the Letter of Credit in
an amount necessary to cure such default ("the Cure Amount") and Tenant agrees
that within ten (10) business days after such initial draw of the Cure Amount,
Tenant shall replenish the Cure Amount and shall cause the Letter of Credit to
be amended in a manner that it is restored to the full amount available
thereunder prior to such draw by Landlord. Tenant further agrees that, in
addition to all of the rights and remedies provided to Landlord pursuant to
Section 22 hereof, whether or not this Lease or Tenant's right to possession
hereunder has been terminated, (a) in the event Tenant is in default (beyond the
expiration of any applicable cure period) under any of the terms,

                                      -30-
<Page>

covenants and conditions of this Lease and Tenant has so failed to replenish the
Letter of Credit as aforesaid, or (b) in the event Tenant has filed (or there
has been filed against Tenant, which petition has not been dismissed within the
time period set forth in Section 22 hereof) a petition for bankruptcy protection
or other protection from its creditors under any applicable and available law,
then Landlord may at once and without notice to Tenant to entitled to draw down
on the entire amount of the Letter of Credit then available to Landlord and
apply such resulting sums toward (i) reimbursement to Landlord for all
Landlord's then unamortized costs incurred in leasing to Tenant the Premises
demised by this Lease, and (ii) reimbursement to Landlord for any other damages
suffered by Landlord as a result of such default.

             B.     Subject to the terms and conditions set forth above, the
foregoing Letter of Credit shall provide for an original expiration date of at
least twelve (12) months following the date of original issuance thereof, and
shall be automatically extended without amendment (subject to the reductions
described in Paragraph A. above) for an additional one-year period from the
original expiration date or any future expiration date thereof, unless sixty
(60) days prior to any such expiration date the bank sends to Landlord by
certified/registered mail, return receipt requested or overnight courier written
advice that the bank has elected not to consider the Letter of Credit renewed
for any such additional one-year period. In the event the bank so advises
Landlord that such Letter of Credit will not be so renewed, Landlord shall
promptly thereafter notify Tenant thereof in writing, and Tenant shall have the
right to obtain a substitute Letter of Credit from a bank reasonably approved by
Landlord meeting all of the terms and conditions described in Paragraph A.
above, which substitute Letter of Credit ("Substitute Letter of Credit") shall
be reasonably satisfactory to Landlord and delivered to Landlord no later than
thirty (30) days prior to the Expiration Date of such Letter of Credit then in
effect. In the event Tenant fails to deliver such Substitute Letter of Credit to
Landlord at least thirty (30) days prior to the Expiration Date of such Letter
of Credit then in effect, Landlord shall in such instance have the right without
further notice to Tenant to immediately draw down on the entire amount of the
Letter of Credit then available to Landlord; in such instance Landlord shall
retain such resulting sum as a Cash Security Deposit, and Landlord shall have
the right to use such Cash Security Deposit to the same extent that Landlord
would be entitled to draw down on the Letter of Credit pursuant to the terms of
Paragraph A. above. At no time shall Landlord draw against the Letter of Credit
(or Cash Security Deposit, as the case may be) in an amount greater than the
amount provided in Paragraph A. above.

             C.     As between Landlord and Tenant only, all draws under the
Letter of Credit and rights of Landlord to apply the proceeds of any such draw
or draft shall be subject to the provisions of this Lease, including all
applicable notice and cure periods provided Section 22 hereof, if any.

             D.     Notwithstanding anything herein to the contrary, in lieu of
the Original Letter of Credit or the Replacement Letter of Credit, Tenant may
deposit with Landlord the equivalent amount(s) of cash, to be held by Landlord
as a Cash Security Deposit (subject to the same reductions as the Letter of
Credit) and applied in the same manner as a draw under the

                                      -31-
<Page>

Letter of Credit in the event of a default by Tenant (after expiration of any
applicable cure period) under this Lease.

             E.     The Letter of Credit, Cash Security Deposit or any
combination thereof held by Landlord pursuant to this Section 25 are hereinafter
referred to as "the Collateral". Tenant acknowledges that Landlord has the right
to transfer or mortgage its interest in the Land and the Building and in this
Lease and Tenant agrees that in the event of any such transfer or mortgage,
Landlord shall have the right to transfer or assign the Collateral to the
transferee or mortgagee. Upon such transfer or assignment and the assumption
thereof by such transferee or assignee, Landlord shall thereby be released by
Tenant from all liability or obligation for the return of such Collateral and
Tenant shall look solely to such transferee or mortgagee for the return of the
Collateral.

     26.     REAL ESTATE BROKER.

             Landlord and Tenant each represents that it has dealt with (and
only with) The John Buck Company and Insignia/ESG, Inc. as brokers in connection
with this Lease, and that insofar as each party knows, no other broker
negotiated this Lease or is entitled to any commission in connection therewith.
Landlord and Tenant each agrees to indemnify, defend and hold the other, its
members and its managers, and any of its or their employees, agents, legal
representatives, officers, partners, successors or assigns harmless from and
against any claims made by any broker or finder other than the brokers named
above for a commission or fee in connection with this Lease, provided that the
party seeking to be indemnified has not in fact retained such broker or finder.

     27.     MISCELLANEOUS.

             A.     RIGHTS CUMULATIVE. All rights and remedies of Landlord under
this Lease shall be cumulative and none shall exclude any other rights and
remedies allowed by law.

             B.     INTEREST. All payments becoming due under this Lease and
remaining unpaid when due shall bear interest until paid at the greater of (i)
twelve percent (12%) per annum or (ii) two percent (2%) per annum above the
prime rate or base rate or other comparable reference rate of interest charged
from time to time by Bank One, N.A. (but in no event at a rate which is more
than the highest rate which is at the time lawful in the State of Illinois).

             C.     TERMS. The necessary grammatical changes required to make
the provisions hereof apply either to corporations or partnerships or
individuals, men or women, as the case may require, shall in all cases be
assumed as though in each case fully expressed.

             D.     BINDING EFFECT. Each of the provisions of this Lease shall
extend to and shall, as the case may require, bind or inure to the benefit not
only of Landlord and of Tenant, but also of their respective successors or
assigns, provided this clause shall not permit any assignment by Tenant contrary
to the provisions of Section 15 hereof.

                                      -32-
<Page>

             E.     LEASE CONTAINS ALL TERMS. All of the representations and
obligations of Landlord are contained herein and in the Work Letter and other
Exhibits attached hereto, and no modification, waiver or amendment of this Lease
or of any of its conditions or provisions shall be binding upon the Landlord
unless in writing signed by Landlord or by a duly authorized agent of Landlord
empowered by a written authority signed by Landlord.

             F.     DELIVERY FOR EXAMINATION. Submission of the Lease for
examination shall not bind Landlord in any manner, and no Lease or obligations
of the Landlord shall arise until this instrument is signed by both Landlord and
Tenant and delivery is made to each.

             G.     NO AIR RIGHTS. No rights to any view or to light or air over
any property, whether belonging to Landlord or any other person, are granted to
Tenant by this Lease.

             H.     MODIFICATION OF LEASE. If any lender requires, as a
condition to its lending funds the repayment of which is to be secured by a
mortgage or trust deed on the Land and Building or either, that certain
modifications be made to this Lease, which modifications will not (i) require
Tenant to pay any additional amounts, or (ii) otherwise change materially or
adversely the rights or obligations of Tenant hereunder, or (iii) reduce the
size of the Premises or change its character or condition, Tenant shall, upon
Landlord's request, execute appropriate instruments effecting such modifications
(so long as Landlord reimburses Tenant for reasonable attorneys' fees incurred
by Tenant in connection with the review of such modifications).

             I.     [Intentionally Omitted.]

             J.     TRANSFER OF LANDLORD'S INTEREST. Tenant acknowledges that
Landlord has the right to transfer its interest in the Land and Building and in
this Lease, and Tenant agrees that in the event of any such transfer and the
assumption of Landlord's obligations hereunder by such transferee, Landlord
shall automatically be released from all liability under this Lease arising
after the date of such transfer and Tenant agrees to look solely to such
transferee for the performance of Landlord's obligations hereunder arising after
the date of such transfer. Tenant further acknowledges that Landlord may assign
its interest in this Lease to a mortgage lender as additional security and
agrees that such an assignment shall not release Landlord from its obligations
hereunder and that Tenant shall continue to look to Landlord for the performance
of its obligations hereunder.

             K.     LANDLORD'S TITLE. Landlord's title is and always shall be
paramount to the title of Tenant. Nothing herein contained shall empower Tenant
to commit or engage in any act which can, shall or may encumber the title of
Landlord.

             L.     PROHIBITION AGAINST RECORDING. Neither this Lease, nor any
memorandum, affidavit or other writing with respect thereto, shall be recorded
by Tenant or by anyone acting through, under or on behalf of Tenant.

                                      -33-

             M.     CAPTIONS. The captions of Paragraphs and subparagraphs are
for convenience only and shall not be deemed to limit, construe, affect or alter
the meaning of such paragraphs or subparagraphs.

             N.     [Intentionally Omitted.]

             O.     ONLY LANDLORD/TENANT RELATIONSHIP. Nothing contained in this
Lease shall be deemed or construed by the parties hereto or by any third party
to create the relationship of principal and agent partnership, joint venturer or
any association between Landlord and Tenant, it being expressly understood and
agreed that neither the method of computation of Rent nor any act of the parties
hereto shall be deemed to create any relationship between Landlord and Tenant
other than the relationship of landlord and tenant.

             P.     APPLICATION OF PAYMENTS. Landlord shall have the right to
apply payments received from Tenant pursuant to this Lease (regardless of
Tenant's designation of such payments) to satisfy any obligations of Tenant
hereunder, in such order and amounts, as Landlord in its sole discretion, may
elect.

             Q.     DEFINITION OF LANDLORD AND TENANT. All indemnities,
covenants and agreements of each of Landlord and Tenant contained herein which
inure to the benefit of the other party shall be construed to also inure to the
benefit of such other party's members and managers and their respective
partners, agents and employees.

             R.     TIME OF ESSENCE. Time is of the essence of this Lease and
each of its provisions.

             S.     TIME FOR PERFORMANCE. Whenever under the terms of this Lease
the time for performance falls on a Saturday, Sunday or holiday, such time for
performance shall be on the next day that is not a Saturday, Sunday or holiday.

             T.     GOVERNING LAW. Interpretation of this Lease shall be
governed by the laws of the State of Illinois.

             U.     PARTIAL INVALIDITY. If any term, provision or condition
contained in this Lease shall, to any extent, be invalid or unenforceable, the
remainder of this Lease (or the application of such term, provision or condition
to persons or circumstances other than those in respect to which it is invalid
or unenforceable) shall not be affected thereby, and each and every other term,
provision and condition of this Lease shall be valid and enforceable to the
fullest extent possible permitted by law.

     28.     NOTICES.

             Unless otherwise expressly authorized pursuant to the terms of this
Lease, all notices to be given under this Lease shall be in writing and (i)
delivered personally (effective the

                                      -34-

                    Chicago, Illinois 60606
                    Attention: Building Manager

or to such other person or such other address designated by notice sent by

             B.     If to Tenant:

                    Attention: General Counsel

or if no address is inserted above, addressed to Tenant at Tenant's present
address, and, after occupancy of the Premises by Tenant, to Tenant at 200 South
Wacker Drive, Chicago, Illinois 60606, or to such other address as is designated
by Tenant in a notice to Landlord.

     29.     LIMITATION ON LANDLORD'S LIABILITY.

             It is expressly understood and agreed by Tenant that none of
Landlord's covenants, undertakings or agreements are made or intended as
personal covenants, undertakings or agreements by Landlord, its members or its
managers, and any liability for damage or breach or nonperformance by Landlord
shall be collectible only out of Landlord's interest in the Building and no
personal liability is assumed by, nor at any time may be asserted against,
Landlord, its members or its managers or any of its or their officers, agents,
employees, legal representatives, successors or assigns, all such liability, if
any, being expressly waived and released by Tenant.

     30.     TENANT ALLOWANCES.

             A.     Tenant shall be entitled to an allowance in an amount not to
exceed $1,342,980.00 (calculated at the rate of $30.00 per rentable square foot
of the Premises) to be applied toward payment or reimbursement of costs incurred
by Tenant in connection with alterations, additions and improvements made to the
Premises pursuant to the Work Letter attached

                                      -35-
<Page>

hereto as Exhibit C, including costs incurred by Tenant in connection with the
preparation of architectural, mechanical, electrical and plumbing drawings for
such work (but excluding furnishings, equipment and personal property purchased
by Tenant), and such other costs incurred by Tenant in connection with
improvements for the Premises for initial occupancy as are approved by and
satisfactory to Landlord. Notwithstanding the foregoing, Tenant may apply a
portion of the Tenant Improvement Allowance, in an amount not to exceed
$335,745.00 (calculated at the rate of $7.50 per rentable square foot of the
Premises), toward the cost of telephone and computer cabling and consulting
costs related thereto. In addition to payment to Tenant of the foregoing Tenant
Improvement Allowance, Landlord further agrees at Landlord's sole cost and
expense to demolish all improvements currently located on the eighteenth (18th)
floor of the Building (except as provided in the Workletter attached hereto as
Exhibit C), and to convert the 18th and 19th floors of the Building to the
Minimum quality Standards set forth on Exhibit J attached hereto.

             B.     The foregoing Tenant Improvement Allowance is for Tenant
personally and may not be applied or used for the benefit of any subtenant
approved by Landlord nor will such allowance inure to the benefit of any
permitted assignee of Tenant. It shall be a condition to the application of any
such Tenant Improvement Allowance that Tenant not be in default under any terms,
covenants or conditions of this Lease at any time such any of allowance is
requested. The Tenant Improvement Allowance is applicable only in connection
with the initial preparation of the Premises for occupancy, it being understood
that the Premises consist of two (2) floors and that the Work therein will be
done in phases, with the Work on the eighteenth (18th) floor completed first,
followed by the Work on the nineteenth (19th) floor. In the event Tenant
requests application of the Tenant Improvement Allowance to any work performed
by contractors hired by Tenant (rather than by Landlord), Tenant shall first
provide to Landlord contractor's affidavits and waivers of lien covering all
labor and materials expended and used, and invoices reasonably acceptable to
Landlord establishing the actual cost of and full payment for all items
purchased with such allowance.

             C.     So long as Tenant has expended at least $895,320.00 of the
Tenant Improvement Allowance (calculated at the rate of $20.00 per rentable
square feet of the Premises) toward the Work described in the Work Letter
(exclusive of design, architectural and engineering fees), Landlord agrees, upon
written request of Tenant, and provided Tenant is not in default under any of
the terms, covenants or conditions of this Lease, to credit any unused portion
of the Tenant Improvement Allowance, up to $223,830.00 (calculated at the rate
of $5.00 per rentable square foot of the Premises), to the Base Rent payable
hereunder by evenly amortizing such unused portion over the remainder of the
initial Term hereof and reducing the monthly installments of Base Rent set forth
in Exhibit B hereof by such amortized amount.

     31.     OPTION TO EXTEND.

             The Term of this Lease may be extended, at the option of Tenant,
for one (1) period of five (5) years, such period being herein sometimes
referred to as the "Extended Term", as follows:

                                      -36-
<Page>

             A.     Such option to extend shall be exercised by Tenant by giving
written notice to Landlord on or before but not later than the last day of the
seventy-fifth (75th) full calendar month of the Term.

             B.     The Extended Term shall be on the same terms, covenants and
conditions of this Lease, excluding the provisions of Sections 30, 31 and 32
hereof, and except for the payment of rent during the Extended Term. Any
termination of this Lease during the original Term of this Lease or the Extended
Term shall terminate all rights hereunder. The option to extend the Term of this
Lease is personal to ORBITZ, LLC and may not be exercised by or for the benefit
of any other party.

             C.     The Base Rent during the Extended Term shall be the Market
Rental Rate as hereafter defined. For purposes of this Lease, "Market Rental
Rate" shall mean the net rental, as of the date for which such Market Rental
Rate is being calculated, per annum per rentable square foot for comparable
space of comparable size, quality and location for a similar term for fully
credit-worthy tenants by reference to first-class space primarily in the
Building, and secondarily in other buildings comparable to the Building in age
and quality in the downtown Chicago area, but excluding those leases where the
tenant has an equity interest in the property. Upon written request of Tenant,
Landlord shall advise Tenant one (1) month prior to the date by which Tenant
must exercise the option granted hereby, of the Market Rental Rate at which it
is prepared to offer the Premises to Tenant for the Extended Term. In addition
to the Base Rent above provided, Tenant shall and hereby agrees to continue to
pay to Landlord Additional Charges in accordance with the provisions of Section
3 of this Lease.

             D.     It shall be a condition of Tenant's right to exercise
Tenant's option to extend the Term of this Lease that Tenant is not in default
under any of the terms, covenants or conditions of this Lease at the time that
Tenant notifies Landlord of the exercise of such option to extend the Term of
this Lease or upon the effective date of such option.

             E.     In the event Tenant exercises Tenant's option under this
Section 31, Tenant agrees to execute and deliver to Landlord a Lease amendment
setting forth the terms of such option within thirty (30) days of exercise of
such option by Tenant.

     32.     TENANT'S OPTION TO TERMINATE.

             Tenant shall have and is hereby granted the option to terminate
this Lease effective on the last day of the thirty-sixth (36th) full calendar
month of the Term (the "Early Termination Date") by:

     (i)     Delivering written notice to Landlord of its exercise of such
termination option on or before the last day of the twenty-eighth (28th) full
calendar month of the Term; and

     (ii)    Paying to Landlord a termination fee in the amount of One Million
Three Hundred Fifty Thousand Dollars ($1,350,000.00). The termination fee shall
be paid to Landlord

                                      -37-
<Page>

as follows: One half (1/2) concurrently with delivery of the notice described in
clause (i), and the remainder no later than the date which is thirty (30) days
prior to the Early Termination Date.

     Tenant's exercise of the foregoing option to terminate this Lease is
further subject to the condition that Tenant is not in monetary default or in
default under any other material term, covenant or condition of this Lease (in
any event beyond the expiration of any applicable cure period) at the time that
Tenant notifies Landlord of the exercise of this termination option or upon the
effective date of such option. Tenant shall deliver the Premises to Landlord on
or before the effective termination date in accordance with the terms and
conditions of this Lease, the same as if such termination date were the original
expiration date of the Term of this Lease.

                                LANDLORD:

                                200 SOUTH WACKER DRIVE, L.L.C.

                                By:  The Equitable Life Assurance Society of the
                                     United States, a New York corporation,

                             200 South Wacker Drive
                                Chicago, Illinois

     This Work Letter is attached to and made part of that certain Lease
(referred to herein for convenience as the "Lease"), dated as of the date hereof
between 200 South Wacker Drive, L.L.C. ("Landlord"), and ORBITZ, LLC ("Tenant"),
wherein the Tenant is leasing certain office space comprised of the entirety of
the eighteenth (18th) and nineteenth (19th) floors and more particularly
described in the Lease (the "Premises") in the building located at 200 South
Wacker Drive, in Chicago, Illinois (the "Building"), as more particularly
described in the Lease. In consideration of the parties entering into the Lease
and of the mutual promises and covenants hereinafter contained, Landlord and
Tenant hereby agree as follows:

     1.      PROPOSED AND FINAL PLANS.

     (a)     Tenant shall cause to be prepared and delivered to Landlord, for
Landlord's approval, the following proposed drawings ("Proposed Plans") for all
improvements Tenant desires to have completed in the Premises (the "Work"):

     (i)     Architectural drawings (consisting of floor construction plan,
             ceiling lighting and layout, power, and telephone plan).

     (ii)    Mechanical drawings (consisting of HVAC, electrical, telephone, and
             plumbing).

     (iii)   Finish schedule (consisting of wall finishes and floor finishes and
             miscellaneous details).

     (b)     All architectural drawings shall be prepared at Tenant's sole cost
and expense (but subject to application of the Tenant Improvement Allowance
provided in Section 30 of the Lease) by Gensler, the architect designated by
Tenant and approved by Landlord, whom Tenant shall employ. Tenant shall deliver
one set of reproducible architectural drawings to Landlord's designated
engineer, Environmental System Designs, Inc. ("ESD") at the same time one set is
delivered to Landlord. All mechanical drawings shall be prepared at Tenant's
sole cost and expense (but subject to application of the Tenant Improvement
Allowance provided in Section 30 of the Lease) by ESD, whom Tenant shall employ.

     (c)     Within seven (7) business days after Landlord's receipt of the
architectural drawings, Landlord shall advise Tenant of any changes required to
obtain Landlord's approval, which approval shall not be unreasonably withheld or
conditioned.

                                       C-l
<Page>

     (d)     Within seven (7) business days after receipt of mechanical
drawings, Landlord shall advise Tenant of any changes required to obtain
Landlord's approval, which approval shall not be unreasonably withheld or
conditioned.

     (e)     If Landlord disapproves of the Proposed Plans, Tenant shall revise
the Proposed Plans disapproved by Landlord and resubmit such plans to Landlord.
Landlord shall, within seven (7) business days after receipt of Tenant's revised
plans, advise Tenant of any additional changes which may be required to obtain
Landlord's approval. If Landlord disapproves the revised plans, Tenant shall
revise such plans and resubmit them to Landlord. Landlord shall, again within
seven (7) business days after receipt of the revised plans, advise Tenant of
further changes, if any, required for Landlord's approval. This process shall
continue until Landlord has approved Tenant's revised Proposed Plans; Landlord
and Tenant shall at all times use all diligence that may be required so that
Landlord has in all events approved Tenant's Proposed Plans or revised Proposed
Plans (as the case may be) on or before, and no later than, November 8, 2000
with respect to the eighteenth (18th) floor and December 21, 2000 with respect
to the nineteenth (19th) floor. Tenant shall further notify Landlord no later
than November 3, 2000 which improvements if any Tenant would like to remain in
that portion of the eighteenth (18th) floor of the Building identified as "Area
Which Tenant May Want Preserved" on Exhibit "A" attached hereto, which Landlord
will not be required to demolish prior to commencement by Landlord of the Work
on such floor. "Final Plans" shall mean the Proposed Plans, as revised, which
have been approved by Landlord and Tenant in writing.

     (f)     All Proposed Plans and Final Plans shall comply with all applicable
statutes, ordinances, regulations, laws, and codes and with the requirements of
Landlord's fire insurance underwriters. Neither review nor approval by Landlord
of the Proposed Plans and resulting Final Plans shall constitute a
representation or warranty by Landlord that such plans either (i) are complete
or suitable for their intended purpose, or (ii) comply with applicable laws,
ordinances, codes and regulations, it being expressly agreed by Tenant that
Landlord assumes no responsibility or liability whatsoever to Tenant or to any
other person or entity for such completeness, suitability or compliance. Tenant
shall not make any changes in the Final Plans without Landlord's prior written
approval.

     2.      PERFORMANCE OF THE WORK BY LANDLORD.

     Upon approval of the Final Plans by Landlord and filing thereof with the
appropriate governmental agencies, Landlord shall cause the Work to be performed
by Turner Construction (Special Projects). Landlord, at Tenant's sole cost and
expense (but subject to application of the Tenant Improvement Allowance provided
in Section 30 of the Lease) shall cause such general contractor to promptly
commence (upon filing of an application for a building permit) to construct and
install and pursue to completion in the Premises the Work (provided that Tenant
agrees to indemnify and hold harmless Landlord, its officers, agents and
employees from any and all costs, liabilities and damages arising from the
commencement of such work prior to issuance of such permit). Landlord shall
cause the Work to be substantially completed on the eighteenth (18th) floor
prior to commencement of construction on the nineteenth (19th) floor. To the
extent

                                       C-2
<Page>

the costs of the Work exceed the Tenant Improvement Allowance, Tenant shall pay
to Landlord the costs of the Work pursuant to the provisions of Paragraph 3
hereof.

     3.      PAYMENT OF COSTS OF THE WORK.

     Subject to the application of the Tenant Improvement Allowance and
Landlord's obligation to demolish at Landlord's sole cost the improvements
currently located on the eighteenth (18th) floor as described in Section 30 of
the Lease, the Work shall be installed at Tenant's sole cost and expense. The
cost of the Work shall include, and Tenant agrees to pay Landlord for, the
following costs ("Landlord's Costs"): (i) the cost of all work performed by
Landlord on behalf of Tenant and for all materials and labor furnished on
Tenant's behalf, (ii) the cost of any services provided to Tenant or its
contractors including but not limited to the cost for rubbish removal, hoisting,
and utilities to the extent not included in any other fees paid by Tenant, and
(iii) a supervision fee equal to Landlord's direct out-of-pocket costs not to
exceed $0.25 per rentable square foot of the Premises (which shall reimburse
Landlord for the costs of providing employees of Landlord for supervising such
work and reviewing the Final Plans and costs for rubbish removal and cleanup
prior to substantial completion of the Work. Landlord may render bills to Tenant
monthly for Landlord's Costs (provided that the supervision fee shall be billed
proportionately based on the cost of the Work performed during the period in
question). All bills shall be due and payable no later than the fifteenth (15th)
day after delivery of such bills to Tenant.

     4.      COMMENCEMENT OF RENT. Notwithstanding the date provided in the
Lease for the commencement of the Term thereof, Tenant's obligation to pay rent
under the Lease as to either floor of the Premises shall not commence until
Landlord shall have substantially completed the Work on such floor; provided
however, that if Landlord shall be delayed in substantially completing the Work
as a result of any of the following (hereinafter "Tenant Delays"):

     (a)     Tenant's failure to obtain Landlord's approval of the Final Plans
in accordance with and on or before the deadlines set forth in Paragraph 1
hereof; or

     (b)     Tenant's failure to advise Landlord by November 4, 2000 which
improvements Tenant does not want demolished on the eighteenth (18th) floor; or

     (c)     Tenant's changes in the Work (notwithstanding Landlord's approval
of such changes); or

     (d)     The performance or failure thereof by Tenant or any person, firm or
entity employed by Tenant, or the completion or failure to complete any work of
Tenant by said person, firm or entity; or

     (e)     Tenant's failure to vacate the nineteenth (19th) floor (of which
Tenant is currently in occupancy as of the date of this Lease pursuant to the
Temporary Space Agreement described in the Lease in a timely and prompt manner
following substantial completion of the Work on the

                                       C-3
<Page>

eighteenth (18th) floor, to enable Landlord to promptly commence construction on
the nineteenth (19th) floor; or

     (f)     Tenant's failure to timely participate in the selection of the
general contractor as set forth in Paragraph 2 hereof; or

     (g)     Any fault of Tenant or its agents or representative;

the payment of rent under the Lease shall not be affected or deferred on account
of any such Tenant Delays.

     Substantial completion of the Work in the Premises shall mean completion of
the Work with the exception of minor or insubstantial details of construction,
mechanical adjustment or decoration, the incompletion of which will not
unreasonably interfere with normal use and occupancy of the Premises by Tenant.
Such minor or insubstantial details are hereinafter referred to as the "Punch
List Items"; Landlord and Tenant will within five (5) business days after
substantial completion of the Work confirm such date in writing and complete
preparation of a written punchlist identifying such items, which Landlord shall
cause to be completed within thirty (30) days thereafter or - if such items
cannot through the use of diligent efforts be completed in such thirty (30) day
period - then as promptly as reasonably possible thereafter. Upon substantial
completion of the Work, Tenant shall accept the Premises, provided, however,
that such acceptance shall not relieve Landlord of its obligation to promptly
complete all Punch List Items.

     5.      ACCESS BY TENANT. Landlord, at Landlord's sole discretion, may
permit Tenant and Tenant's agents to enter the Premises as licensees prior to
the date specified as the commencement of the Term of said Lease in order that
Tenant may do such other work as may be required by Tenant to make the Premises
ready for Tenant's use and occupancy thereof. If Landlord permits such entry
prior to the commencement of the Term, such license is conditioned upon Tenant
and Tenant's agents, contractors, workmen, mechanics, suppliers and invitees
working in harmony and not interfering with Landlord or Landlord's agents in
constructing and installing the Work or doing any other work in or about the
Premises or Building, or with other tenants, invitees and occupants of the
Building. If at any time such entry shall cause or threaten to cause such
disharmony or interference therewith, Landlord shall have the right to withdraw
such license upon twenty-four (24) hours' written notice to Tenant. Tenant
agrees that any such entry into and occupation of the Premises shall be deemed
to be under all of the terms, covenants, conditions and provisions of the Lease
except as to the covenant to pay rent, and further agrees that Landlord shall
not be liable in any way for any injury, loss or damage which may occur to any
of Tenant's work or installations made in the Premises or to property placed
therein, and Tenant agrees to protect, defend, indemnify and save harmless
Landlord and Landlord's principals, agents, beneficiaries and employees from all
liabilities, costs, damages, fees and expenses arising out of or in any way
connected with the activities of Tenant or its agents, contractors, suppliers or
workmen in or about the Premises or Building.

                                       C-4
<Page>

     In the event Tenant employs contractors to do work in the Premises, Tenant
shall secure and pay for Worker's Compensation, Employers Liability Insurance,
and Comprehensive General Liability Insurance in forms and amounts acceptable to
Landlord. All policies shall be endorsed to include Landlord and its employees
and agents as additional insured parties. Certified copies of such policies or,
at Landlord's election, certificates of such insurance shall be delivered to
Landlord prior to Tenant commencing any work in the Premises.

     6.      MISCELLANEOUS.

     (a)     Except as expressly set forth herein, Landlord has no other
agreement with Tenant and Landlord has no other obligation to do any other work
or pay any amounts with respect to the Premises. Any other work in the Premises
which may be permitted by Landlord pursuant to the terms and conditions of the
Lease shall be done at Tenant's sole cost and expense and in accordance with the
terms and conditions of the Lease.

     (b)     This Work Letter shall not be deemed applicable to any additional
space added to the original Premises at any time or from time to time, whether
by any options under the Lease or otherwise, or to any portion of the original
Premises or any additions thereto in the event of a renewal or extension of the
initial term of the Lease, whether by any options under the Lease or otherwise,
unless expressly so provided in the Lease or any amendment or supplement
thereto.

     (c)     The failure by Tenant to pay any monies due Landlord pursuant to
this Work Letter within the time period herein stated shall be deemed a default
under the terms of the Lease for which Landlord shall be entitled to exercise
all remedies available to Landlord for nonpayment of Rent. All late payments
shall bear interest pursuant to Section 27.B of the Lease.

     (d)     Tenant shall be solely responsible to determine at the site all
dimensions of the Premises and the Building which affect any work to be
performed by Tenant hereunder.

                        FORM OF NON-DISTURBANCE AGREEMENT

     THIS AGREEMENT, made this       day of              , 2000, by and between
___________________, a ______________________ (herein "Lessee"), and
MASSACHUSETTS MUTUAL LIFE INSURANCE COMPANY, a Massachusetts corporation
(herein "Lender").

                                    RECITALS

     A.      Lender is the holder of a certain promissory note (herein the
"Note") issued by 200 South Wacker Drive, L.L.C. ("Lessor"), dated October 23,
1998 in the principal sum of Sixty-Six Million and No/100 DOLLARS
($66,000,000.00) and of the Mortgage and Security Agreement of even date
therewith (herein the "Mortgage") securing the Note, recorded on October 26,
1998 as Document Number 98958719 with the Cook County Recorder, which Mortgage
encumbers the real property (herein called the "Subject Property") described on
Exhibit A, attached hereto and made a part hereof.

     B.      Lessee and 200 South Wacker Drive, L.L.C., as Lessor, entered into
a lease agreement (herein the "Lease") dated ____________, 2000 by which Lessee
leased from Lessor certain premises commonly known as the _____________________
floor(s) and comprising approximately _________________ Square Feet (herein the
"Leased Premises"), and constituting a portion of the Subject Property.

     C.      Lessee desires to be able to obtain the advantages of the Lease and
occupancy thereunder in the event of foreclosure of the Mortgage and Lender
wishes to have Lessee confirm the priority of the Mortgage over the Lease.

     NOW, THEREFORE, in consideration of the mutual covenants and conditions set
forth hereinbelow, the parties hereto agree as follows:

     1.      Lessee hereby covenants and agrees that all its rights and
interests whatsoever under the Lease in the Leased Premises and the Subject
Property are and shall remain subject and subordinate to the lien of the
Mortgage and to all the terms, conditions and provisions thereof, to all
advances made or to be made thereunder or under the Note, and to any increases,
renewals, extensions, modifications, substitutions, consolidations or
replacements thereof or of the Note.

     2.      So long as Lessee is not in default (beyond any period given Lessee
in the Lease to cure such default) in the payment of rent or additional charges
or in the performance of any of the other terms, covenants or conditions of the
Lease on Lessee's part to be performed, Lessee shall not be disturbed by Lender
in its possession of the Leased Premises during the term of the Lease, or any
extension or renewal thereof, or in the enjoyment of its rights under the Lease.

                                       I-1
<Page>

     3.      If the interest of the Lessor under the Lease shall be acquired by
Lender or any purchaser ("Purchaser") by reason of exercise of the power of sale
or the foreclosure of the Mortgage or other proceedings brought to enforce the
rights of the holder thereof, by deed in lieu of foreclosure or by any other
method, and Lender or Purchaser succeeds to the interest of Lessor under the
Lease, Lessee shall attorn to Lender or Purchaser as its lessor, said attornment
to be effective and self-operative without the execution of any other
instruments on the part of either party hereto immediately upon Lender's or
Purchaser's succeeding to the interest of the Lessor under the Lease, and the
Lease shall continue in accordance with its terms between Lessee as lessee and
Lender or Purchaser as lessor; provided, however, that:

     (a)     Lender shall not be personally liable under the Lease and Lender's
liability under the Lease shall be limited to the ownership interest of Lender
in the Subject Property;

     (b)     Lender shall not be liable for any act or omission of any prior
lessor (including Lessor);

     (c)     Lender shall not be subject to any offsets or defenses which Lessee
might have against any prior lessor (including Lessor);

     (d)     Lender shall not be bound by any prepayment of rent more than
thirty (30) days in advance, or by any deposit, rental security or any other
sums deposited with any prior lessor (including Lessor) under the Lease unless
actually received by Lender;

     (e)     Lender shall not be bound by any agreement or modification of the
Lease made without Lender's consent;

     (f)     Lender shall not be bound to commence or complete any construction
or to make any contribution toward construction or installation of any
improvements upon the Leased Premises required under the Lease or any expansion
or rehabilitation of existing improvements thereon, or for restoration of
improvements following any casualty not required to be insured under the Lease
or for the costs of any restorations in excess of any proceeds recovered under
any insurance required to be carried under the Lease; and,

     (g)     Lender shall not be bound by any restriction on competition beyond
the Subject Property.

     4.      [NOTE: THIS PARAGRAPH 4 SHALL BE ADAPTED AS NECESSARY TO REFLECT
THE CURRENT STATE OF COMPLETION OF THE WORK DESCRIBED IN THE WORKLETTER ATTACHED
AS EXHIBIT C TO THE LEASE.] Lessee certifies to Lender that the Lease is
presently in full force and effect with no defaults thereunder by the Lessor or
by Lessee and unmodified except as indicated hereinabove; that the term thereof
has commenced and the full rental is now accruing thereunder; that Lessee has
accepted possession of the Leased Premises and that any improvements required by
the terms of the Lease to be made by the Lessor have been completed to the
satisfaction of Lessee; that no rent under the Lease has been paid more than

Leased Premises; and that the Lessee, has no charge, lien, claim or offset under
the Lease or otherwise, against rents or other charges due or to become due
thereunder.

     5.      Lessee agrees with Lender that from and after the date hereof,
Lessee will not terminate or seek to terminate the Lease by reason of any act or
omission of the Lessor thereunder until Lessee shall have given written notice,
by registered or certified mail, return receipt requested, of said act or
omission to Lender, which notice shall be addressed to Massachusetts Mutual Life
Insurance Company, C/O David L. Babson and Company Incorporated, 1295 State
Street, Springfield, Massachusetts 01111, Attention: Senior Managing Director,
Real Estate Finance Group, and until a reasonable period of time shall have
elapsed following the giving of such notice, during which period Lender shall
have the right, but shall not be obligated, to remedy such act or omission.

     6.      This Agreement shall inure to the benefit of and shall be binding
upon Lessee and Lender, and their respective heirs, personal representatives,
successors and assigns. This Agreement may not be altered, modified or amended
except in writing signed by all of the partied hereto. In the event any one or

to be invalid, illegal or unenforceable in any respect, such invalidity,
