pursuant to the requirements of either the Securities Act or the Securities
Exchange Act, the Company shall use its reasonable best efforts to file all
reports required to be filed by it under the Securities Act and the Securities
Exchange Act and the rules and regulations adopted by the Securities and
Exchange Commission thereunder and shall take such further action as any holder
or holders of Underlying Class A Common Stock may reasonably request, all to the
extent required to enable such holders to sell Underlying Class A Common Stock
pursuant to  Rule 144 adopted by the Securities and Exchange Commission under
the Securities Act (as such rule may be amended from time to time) or any

any Subsidiary to, disclose any Purchaser's (or any of its Affiliate's) name or
identity as an investor in the Company in any press release or other public
announcement or in any document or material filed with any governmental entity,

disclosure the Company shall give written notice to such Purchaser, describing
in reasonable detail the proposed content of such disclosure and shall permit
such Purchaser to review and comment upon the form and substance of such
disclosure.

          3G.  Equity Issuances.
               ----------------

               (i)    If after the Signing the Company authorizes the issuance
     or sale of any Equity Securities, the Company shall offer to sell to each
     holder of Underlying Class A Common Stock a portion of such stock or
     securities equal to the quotient determined by dividing (1) the number of
     shares of Underlying Class A Common Stock held by such holder by (2) the
     total number of shares of Common Stock outstanding on a fully diluted
     basis. Each holder of Underlying Class A Common Stock shall be entitled to
     purchase such stock or securities at the most favorable price and on the
     most favorable terms as such stock or securities are to be offered to any
     other Persons. The purchase price for all stock and securities offered to
     the holders of the Underlying Common Stock shall be payable in cash;
     provided that, if other Persons are to pay for such Equity Securities in
     whole or in part with consideration other than cash, then the Board, in its
     sole discretion, shall make a determination of the fair market value of
     such consideration, and each holder of Underlying Class A Common Stock will
     be entitled to purchase the Equity Securities for cash equal to the fair
     market value of the aggregate cash and non-cash consideration each of them
     would otherwise pay hereunder. Notwithstanding the foregoing, none of the
     holders of Underlying Class A Common Stock will be permitted to exercise
     its rights under this Section 3G unless it agrees to purchase its
                           ----------
     proportionate amount of each class or series of securities offered as a
     package or unit in the issuance of the Equity Securities.

               (ii)   In order to exercise its purchase rights hereunder, a
     holder of Underlying Class A Common Stock must, within 30 days after
     receipt of written notice from the Company describing in reasonable detail
     the stock or securities being offered, the purchase price thereof, the
     payment terms and such holder's percentage allotment, deliver a written
     notice to the Company describing its election hereunder (including the
     amount of Equity Securities it so elects to purchase); provided that
     funding the purchase of Equity Securities may be subject to the expiration
     or termination of any applicable waiting period under the HSR Act. If all
     of the stock and securities offered to the holders of Underlying Class A
     Common Stock is not fully subscribed by such holders, the remaining stock
     and securities shall be reoffered by the Company to the holders purchasing
     their full allotment upon the terms set forth in this Section 3G, except
                                                           ----------
     that such holders must exercise their purchase rights within five days
     after receipt of such reoffer.

               (iii)  Upon the expiration of the offering periods described
     above, the Company shall be entitled to sell such stock or securities which
     the holders of Underlying Class A Common Stock have not elected to purchase
     during the 60 days following such expiration on terms and conditions no
     more favorable to the purchasers thereof than those offered to such
     holders. Any stock or securities offered or sold by the Company after such

                                      -9-
<PAGE>

     60-day period must be reoffered to the holders of Underlying Class A Common
     Stock pursuant to the terms of this Section 3G.
                                         ----------

               (iv)   The Company shall promptly deliver to holders of
     Underlying Class A Common Stock certificates evidencing the Equity
     Securities purchased by each such party hereunder, upon receipt of payment
     therefor, and upon execution of such documents and instruments as shall
     govern the issuance of such Equity Securities (which documents and
     instruments shall be substantially the same as those governing the issuance
     of the Equity Securities to other Persons).

               (v)    Notwithstanding anything to the contrary herein, the
     rights of the holders of Underlying Class A Common Stock under this Section
                                                                         -------
     3G may be waived on behalf of all holders of Underlying Class A Common
     --
     Stock by the vote of at least (a) a majority of the outstanding Purchaser
     Shares held by Corporate Investors, and, (b) a majority of the outstanding
     Purchaser Shares held by Financial Investors; provided that only Persons
     not participating in the relevant financing may be counted towards, and
     participate in, such vote.

          3H.  FIRPTA.
               ------

               (i)    The Company acknowledges that certain Purchasers may be
     foreign entities or have foreign Persons as partners and that the Company
     may be required to file or cause to be filed in the future with the IRS
     certain statements with its United States income tax returns required under
     Section 1.897-2(h) of the Treasury Regulations. The Company shall use
     reasonable efforts consistent with sound business practice to avoid
     becoming a "United States real property holding corporation" within the
     meaning of Section 897(c)(2) of the IRC. Upon any Purchaser's request, the
     Company shall provide such Purchaser with a statement that the Company is
     or is not a "United States real property holding corporation" as of the
     date specified by such Purchaser (or as of the date of the request if such
     Purchaser does not specify a date) and shall send a copy of such statement
     to the IRS in a form and manner which identifies such Purchaser and which
     otherwise satisfies the requirements of Section 1.89-2(h)(2) of the
     Treasury Regulations.

               (ii)   In the event the Company in the future becomes a "United
     States real property holding corporation," the Company shall promptly
     notify each Purchaser in writing of such fact. Thereafter, upon written
     request from any Purchaser, the Company shall provide information,
     documentation and assistance to such Purchaser reasonably related to the
     Company's status as a "United States real property holding corporation,"
     including but not limited to (i) an affidavit stating (if true) that the
     stock held by such Purchaser is of a class that is regularly traded (as
     defined by Sections 1.897-1(n) and 1.897-9T of the Treasury Regulations) on
     an established securities market (as defined by Section 1.897-1(m) of the
     Treasury Regulations), and (ii) information or assistance which would
     enable such Purchaser to obtain a withholding certificate permitting a
     transferee of such Purchaser's stock to avoid or reduce any withholding
     obligation such transferee would otherwise have under federal tax law.

                                      -10-
<PAGE>

          3I.  VCOC Covenants.  Each holder of Series D Preferred Stock, Series
               --------------
D-1 Preferred Stock or Underlying Class A Common Stock which is intended to
qualify as a "venture capital operating company" for purposes of Department of
Labor Regulation (S)2510.3-101 shall, in addition to all other rights granted
under this Agreement and the other agreements contemplated hereby, have the
right to consult with and advise the officers of the Company with respect to the
management of the Company and its Subsidiaries.

          3J.  Unrelated Business Taxable Income.  The Company shall not engage
               ---------------------------------
in any transaction which is reasonably likely to cause any Purchaser or any of
its limited partners which are exempt from income taxation under Section 501(a)
of the IRC and, if applicable, any pension plan that any such trust may be a
part of, to recognize unrelated business taxable income as defined in Section
512 and Section 514 of the IRC.

          3K.  Regulatory Compliance Cooperation.
               ---------------------------------

     Before the Company redeems, purchases or otherwise acquires, directly or
indirectly, or converts or takes any action with respect to the voting rights
of, any shares of any class of its capital stock or any securities convertible
into or exchangeable for any shares of any class of its capital stock, the
Company shall give written notice of such pending action to any Purchaser that
is a bank holding company (a "BHC Purchaser").  Upon the written request of any
                              -------------
BHC Purchaser made within 10 days after its receipt of any such notice stating
that after giving effect to such action such BHC Purchaser would have a
Regulatory Problem (as defined below), the Company shall defer taking such
action for such period (not to extend beyond 45 days (or 10 days in the case of
the following proviso) after such BHC Purchaser's receipt of the Company's
original notice) as such BHC Purchaser requests to permit it and its Affiliates
to reduce the quantity of the Company's securities they own in order to avoid
the Regulatory Problem; provided, however, that if such BHC Purchaser would have
a Regulatory Problem as a result of the conversion of Series D Preferred Stock
into Class A Common Stock by another Purchaser, such BHC Purchaser shall be
required to convert a sufficient number of shares of Series D Preferred Stock
into shares of Series D-1 Preferred Stock so that the BHC Purchaser can avoid
the Regulatory Problem within 10 days of receipt of the Company's original
notice.  In addition, the Company shall not be a party to any merger,
consolidation, recapitalization or other transaction pursuant to which any BHC
Purchaser would be required to take any voting securities, or any securities
convertible into voting securities, which might reasonably be expected to cause
such BHC Purchaser to have a Regulatory Problem.  The Company shall grant to any
subsequent holder of the Underlying Class A Common Stock owned by a BHC
Purchaser, upon such holder's request, the same rights granted to the BHC
Purchasers pursuant to this Section 3K. For purposes of this Section 3K, a
                            ----------                       ----------
Person shall be deemed to have a "Regulatory Problem" when such Person and such
                                  ------------------
Person's Affiliates would own, control or have power over a greater quantity of
securities of any kind issued by the Company or any other entity than are
permitted under the BHCA (as defined below) and the regulations promulgated
thereunder.

          3L.    Amendment of Certificate of Designation.  Prior to Closing, the
                 ---------------------------------------
Company will use its reasonable best efforts to (A) amend the Certificate of
Designation (and BOEC shall

                                      -11-
<PAGE>

have the right to review and approve such amended Certificate of Designation) to
create a new class of preferred stock, the "Series D-1 Preferred Stock", and
                                            --------------------------
authorize the issuance of up to 15,000,000 shares of such Series D-1 Preferred
Stock which Series D-1 Preferred Stock shall (i) be identical in all respects to
the Series D Preferred Stock, except that the Series D-1 Preferred Stock shall
have no voting rights, except as shall be required by law and (ii) be
automatically convertible into Series D Preferred Stock (on a one-to-one basis)
on the later to occur of (A) March 11, 2000 or (b) such time as BOEC is
permitted, under the Bank Holding Company Act of 1956, as amended (the "BHCA"),
                                                                        ----
to hold such number of shares of Series D Preferred Stock and (B) provide any
BHC Purchaser with an opinion of counsel with respect to the Series D-1
Preferred Stock substantially similar to paragraphs 9 and 10 of Exhibit E-1
attached hereto. In any event, the Company shall cause the representations and
warranties in Section 4B and Section 4D below that specifically refer to the
              ----------     ----------
Series D-1 Preferred Stock to be correct as of the Closing for BOEC. In
addition, the amendment to the Certificate of Designation will provide that any
BHC Purchaser may convert shares of Series D Preferred Stock into shares of
Series D-1 Preferred Stock (on a one-to-one basis) in order to avoid a
Regulatory Problem. BOEC will inform the Company, in writing, at such time that
BOEC is permitted, under the BHCA, to hold such number of shares of Series D
Preferred Stock, which writing shall be determinative for all purposes of this
Section 3L and the conversion of such shares pursuant to the amended Certificate
----------
of Designation. Each Purchaser hereby agrees to provide a consent to the
amendment of the Certificate of Designation described in this Section 3L
                                                              ----------
promptly upon the Company's request. For purposes of this Agreement and the
other Transaction Documents, outstanding shares of Series D-1 Preferred Stock
shall not be counted in any calculation of votes or voting percentages with
respect to the Series D Preferred Stock, the Purchaser Shares and the Underlying
Class A Common Stock.

          3M.  Non-Solicitation. The Company hereby agrees that it shall not,
               ----------------
for the one year period following the date of Signing, directly or indirectly,
without the prior written consent of such Purchaser, hire, recruit or solicit
for employment, any employee of a Purchaser or any individual who is or was
employed by a Purchaser during the thirty (30) day period immediately preceeding
the Signing date.

          3N.  Termination.   Notwithstanding anything to the contrary herein,
               -----------
the provision of Section 3A through 3D, Section 3G, Section 3K and Section 3L
                 ----------         --  ----------  ----------     ----------
shall terminate on a Qualified IPO.

          Section  4.    Representations and Warranties of the Company.
                         ---------------------------------------------

          As a material inducement to each Purchaser to enter into this
Agreement and purchase the Series D Preferred Stock and Series D-1 Preferred
Stock hereunder, the Company hereby represents and warrants as of the Signing

presently proposed to be conducted and to carry out the transactions
contemplated by this Agreement and the other Transaction Documents (other than

Company makes no such representation). The copies of the Company's and each
Subsidiary's charter documents and bylaws which have been furnished to the
Purchasers' special counsel reflect all amendments made thereto at any time
prior to the date of this Agreement and are correct and complete.

          6C.  Purchaser's Investment Representations.  Each Purchaser hereby
               --------------------------------------
represents and warrants (as to itself only) to the Company that:

               (a)  Investment Purpose. Such Purchaser (i) is acquiring the
                    ------------------
     Series D Preferred Stock or Series D-1 Preferred Stock and (ii) upon
     conversion of the Series D Preferred Stock, will acquire the Underlying
     Class A Common Stock then issuable (the Series D Preferred Stock, the
     Series D-1 Preferred Stock and the Underlying Class A Common Stock
     collectively are referred to herein as the "Securities"), for its own
                                                 ----------
     account for investment only and not with a view towards, or for resale in
     connection with, the public sale or distribution thereof, except pursuant
     to sales registered or exempted under the Securities Act.

               (b)  Accredited Investor Status. Such Purchaser is an "accredited
                    --------------------------
     investor" as that term is defined in Rule 501(a)(3) of Regulation D.

               (c)  Reliance on Exemptions.  Such Purchaser understands that the
                    ----------------------
     Securities are being offered and sold to it in reliance on specific
     exemptions from the registration requirements of United States federal and
     state securities laws and that the Company is relying in part upon the
     truth and accuracy of, and such Purchaser's compliance with, the
     representations, warranties and agreements of such Purchaser set forth
     herein in order to determine the availability of such exemptions and the
     eligibility of such Purchaser to acquire such securities.

               (d)  Information. Such Purchaser has been furnished with all
                    -----------
     materials relating to the business, finances and operations of the Company
     and materials relating to

                                      -23-
<PAGE>

     the offer and sale of the Securities which have been requested by such
     Purchaser. Such Purchaser has been afforded the opportunity to ask
     questions of the Company. Such Purchaser understands that its investment in
     the Securities involves a high degree of risk. Such Purchaser has sought
     such accounting, legal and tax advice as it has considered necessary to
     make an informed investment decision with respect to its acquisition of the
     Securities.

               (e)  No Governmental Review. Such Purchaser understands that no
                    ----------------------
     United States federal or state agency or any other government or
     governmental agency has passed on or made any recommendation or endorsement
     of the Securities or the fairness or suitability of the investment in the
     Securities nor have such authorities passed upon or endorsed the merits of
     the offering of the Securities.

               (f)  Transfer or Resale. Such Purchaser understands that except
                    ------------------
     as provided in the Registration Agreement: (i) the Securities have not been
     and are not being registered under the Securities Act or any state
     securities laws, and may not be offered for sale, sold, assigned or
     transferred unless (A) subsequently registered thereunder or (B) sold in
     reliance on an exemption therefrom; and (ii) neither the Company nor any
     other person is under any obligation to register such securities under the
     Securities Act or any state securities laws or to comply with the terms and
     conditions of any exemption thereunder. Such Purchaser is able to bear the
     economic risk of its investment in the Securities for an indefinite period
     of time.

               (g)  Enforceability. This Agreement constitutes the legal, valid
                    --------------
     and binding obligation of such Purchaser, enforceable in accordance with
     its terms, and the execution, delivery and performance of this Agreement by
     such Purchaser does not and shall not conflict with, violate or cause a
     breach of any material agreement, contract or instrument to which Purchaser
     is a party or any judgment, order or decree to which such Purchaser is
     subject.

          6D.  Consent to Amendments.  Except as otherwise expressly provided
               ---------------------
herein, the provisions of this Agreement may be amended and the Company may take
any action herein prohibited, or omit to perform any act herein required to be
performed by it, only if the Company has obtained the written consent of the
holders of (i) a majority of the outstanding Purchaser Shares held by the
Corporate Investors and (ii) a majority of the outstanding Purchaser Shares held
by the Financial Investors.  No other course of dealing between the Company and
the holder of any Underlying Class A Common Stock or any delay in exercising any
rights hereunder or under the Amended Certificate (as may be amended) shall
operate as a waiver of any rights of any such holders.  For purposes of this
Agreement, shares of the Series D Preferred Stock held by the Company or any
Subsidiaries (and shares issued or issuable upon conversion of such Series D
Preferred Stock) shall not be deemed to be outstanding.

          6E.  Survival of Representations and Warranties.  All representations
               ------------------------------------------
and warranties contained herein or made in writing by any party in connection
herewith shall survive the execution and delivery of this Agreement and the
consummation of the transactions

                                      -24-
<PAGE>

contemplated hereby, regardless of any investigation made by any Purchaser or on
its behalf; provided that all of the representations and warranties contained
herein, other than those contained in Sections 4B, 4D, 4J, 4P, 4Q and 4R (each
of which shall survive the Signing indefinitely), shall survive the Signing for
one (1) year after the date of this Agreement.

          6F.  Successors and Assigns.  Except as otherwise expressly provided
               ----------------------
herein, all covenants and agreements contained in this Agreement by or on behalf
of any of the parties hereto shall bind and inure to the benefit of the
respective successors and assigns of the parties hereto whether so expressed or
not.  In addition, and whether or not any express assignment has been made, the
provisions of this Agreement which are for any Purchaser's benefit as a
purchaser or holder of shares of the Series D Preferred Stock, Series D-1
Preferred Stock or Underlying Class A Common Stock are also for the benefit of,
and enforceable by, any subsequent holder of such Series D Preferred Stock,
Series D-1 Preferred Stock or such Underlying Class A Common Stock, except that
the indemnity obligations of the Company set forth in Section 6N may be enforced
                                                      ----------
only by each Purchaser. The rights and obligations of each Purchaser under this
Agreement and the agreements contemplated hereby may be assigned by such
Purchaser at any time, in whole or in part, to any investment fund managed by
such Purchaser, or any successor thereto.

          6G.  Severability. Whenever possible, each provision of this Agreement
               ------------
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be prohibited
by or invalid under applicable law, such provision shall be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of this Agreement.

          6H.  Counterparts.  This Agreement may be executed simultaneously in
               ------------
two or more counterparts, any one of which need not contain the signatures of
more than one party, but all such counterparts taken together shall constitute
one and the same Agreement.

          6I.  Descriptive Headings; Interpretation.  The descriptive headings
               ------------------------------------
of this Agreement are inserted for convenience only and do not constitute a
substantive part of this Agreement.  The use of the word "including" in this
Agreement shall be by way of example rather than by limitation.

          6J.  Generally Accepted Accounting Principles.  Where any accounting
               ----------------------------------------
determination or calculation is required to be made under this Agreement or the
exhibits hereto, such determination or calculation (unless otherwise provided)
shall be made in accordance with generally accepted accounting principles,
consistently applied, except that if because of a change in generally accepted
accounting principles the Company would have to alter a previously utilized
accounting method or policy in order to remain in compliance with generally
accepted accounting principles, such determination or calculation shall continue
to be made in accordance with the Company's previous accounting methods and
policies.

          6K.  Governing Law.  The corporate law of the State of Delaware shall
               -------------
govern all issues and questions concerning the relative rights and obligations
of the Company and its stockholders.  All other issues and questions
concerning the construction, validity,

                                      -25-
<PAGE>

enforcement and interpretation of this Agreement and the exhibits and schedules
hereto shall be governed by, and construed in accordance with, the laws of the
State of Illinois, without giving effect to any choice of law or conflict of law
rules or provisions (whether of the State of Illinois or any other jurisdiction)
that would cause the application of the laws of any jurisdiction other than the
State of Illinois. In furtherance of the foregoing, the internal law of the
State of Illinois shall control the interpretation and construction of this
Agreement (and all schedules and exhibits hereto), even though under that
jurisdiction's choice of law or conflict of law analysis, the substantive law of
some other jurisdiction would ordinarily apply.

          6L.  Notices.  All notices, demands or other communications to be

               ----------------------
jointly in the negotiation and drafting of this Agreement.  In the event an
ambiguity or question of intent or interpretation arises, this Agreement shall

          6N.  Indemnification.  In consideration of each Purchaser's execution
               ---------------
and delivery of this Agreement and acquiring the Series D Preferred Stock and
Series D-1 Preferred Stock hereunder and in addition to all of the Company's

     -----------
suits, claims, losses, costs, penalties, fees, liabilities and damages, and

<PAGE>

Indemnitee is a party to the action for which indemnification hereunder is

 -----------------------
result of, or arising out of, or relating to any misrepresentation in or breach

Indemnitee under this Section 6N for any liability if such liability is caused
                      ----------
solely by such Indemnitee's fraud, willful misconduct or gross negligence or
default or breach under this Agreement or the Registration Agreement. To the
extent that the foregoing undertaking by the Company may be unenforceable for
any reason, the Company shall make the maximum contribution to the payment and
satisfaction of each of the Indemnified Liabilities which is permissible under
applicable law.

          6O.  Understanding Among the Purchasers.  The determination of each
               ----------------------------------
Purchaser to purchase shares of the Series D Preferred Stock and Series D-1
Preferred Stock pursuant to this Agreement has been made by such Purchaser
independent of any other Purchaser and independent of any statements or opinions
as to the advisability of such purchase or as to the properties, business,
prospects or condition (financial or otherwise) of the Company and its
Subsidiaries which may have been made or given to such Purchaser by any other
Purchaser or by any agent or employee of any other Purchaser. Each Purchaser
acknowledges and agrees that no other Purchaser shall be responsible in any way
or held liable or accountable to any extent for any information, documents,
materials, analysis, projections, plans or other data (or compilations thereof)
relating to the Company or the transactions contemplated hereby (collectively,
"Investment Data") provided to such Purchaser by any other Purchaser, and each
 ---------------
Purchaser agrees to hold harmless and not make any claims against any other
Purchaser with respect to any Investment Data provided to such Purchaser by such
other Purchaser. In addition, it is acknowledged by each of the other Purchasers
that neither of Frontenac or BOEC has acted as an agent of such Purchaser in
connection with making its investment hereunder and that neither of Frontenac or
BOEC shall be acting as an agent of such Purchaser in connection with monitoring
its investment hereunder.

          6P.  Acknowledgment re Kirkland & Ellis. Frontenac and BOEC have
               ----------------------------------
retained Kirkland & Ellis in connection with the purchase of Series D Preferred
Stock and Series D-1 Preferred Stock pursuant to this Agreement and may in the

this Agreement. Each of the other Purchasers understands that Kirkland & Ellis
is not representing and shall not be deemed to be representing any of such other
Purchasers in connection with the purchase of Series D Preferred Stock pursuant
to this Agreement or other matters contemplated by this Agreement unless and
until (i) specifically requested by such other Purchasers and agreed to by
Kirkland & Ellis, and (ii) such other Purchasers sign a written retention and
conflict waiver letter provided by Kirkland & Ellis.
