Company and the Purchasers. At the Closing, the Company shall deliver to each of

         of securities of the Company (whether under this Agreement, the

         Incorporation or otherwise), the SBIC Holder shall have the right to
         the extent required under the SBIC Regulations to demand the immediate

         for such stock, plus all accrued or declared and unpaid dividends and
         interest thereon, if any, by delivering written notice of such demand

         upon such payment, the SBIC Holder shall deliver the certificates or

         transfer its securities without regard to any restriction on transfer
         set forth in this Agreement or any other agreement to which the SBIC
         Holder is a party (other than the securities laws restrictions);

         exchange all or any portion of any voting security then held by it on a
         share-for-share basis for shares of a nonvoting security of the
         Company, which nonvoting security shall be identical in all respects to
         the voting security exchanged for it, except that it shall be nonvoting
         and shall be convertible into a voting security on such terms as are
         requested by such SBIC Holder in light of regulatory considerations
         then prevailing, (c) continue and preserve the respective allocations
         of the voting interests with respect to the Company arising out of such
         SBIC Holder's ownership of voting securities and/or provided in the
         Stockholders Agreement before the transfers and amendments referred to
         above (including entering into such additional agreements as are
         reasonably requested by such SBIC Holder to permit any Person(s)
         designated by such SBIC Holder to exercise any voting power which is
         relinquished by the SBIC Holder), and (d) amend this Agreement, the
         Stockholders Agreement, the Registration Agreement, the Company's
         Articles of Incorporation, the Company's Bylaws and related agreements

entered into at or prior to the Closing, or any action or inaction at or prior

than: (a) liabilities fully disclosed and adequately provided for in the Latest

interest in, the properties and assets it uses, the properties and assets shown

disposed of in the ordinary course of business since the date of the Latest
Balance Sheet and except for Liens disclosed on the Latest Balance Sheet
(including any notes thereto). Except as described on the attached Assets
Schedule, buildings, equipment and other tangible assets of the Company are in

in the ordinary course of business.

                  5I.      Investment Company Act.  The Company is not an

                  5J. Margin Regulations. The Company does not own any "margin
security" as such term is defined in Regulation U of the Federal Reserve Board,
and none of the proceeds of the Common Stock will be used, directly or
indirectly, for the purpose of purchasing or carrying any margin security, for
the purpose of reducing or retiring any indebtedness which was originally
incurred to purchase or carry any margin security or for any other purpose which
might cause any of the securities purchased under this Agreement to be
considered "purpose credit" within the meaning of Regulations T, U or X of the
Federal Reserve Board. The Company has not taken or permitted, and will not
permit any agent acting on its behalf to take, any action which might cause this
Agreement or any document or instrument delivered hereunder to violate such
Regulation T, U or X, any other regulation of the Federal Reserve Board, or
Section 8 of the Exchange Act or any rule or regulation thereunder. No proceeds
of the issuance of the Common Stock will be used to acquire any security in any
transaction which is subject to Section 13 or 14 of the Exchange Act, including

Section 1.1502-6 of the Treasury Regulations (or any similar provision of state,
local or foreign law), as a transferee or successor, by contract, or otherwise.

pay all of the current Tax liabilities of the Company, if the current Tax year
were treated as having ended on the date of the Latest Balance Sheet consistent
with past practices.

jurisdiction

                                      -34-

<PAGE>

of the aforesaid courts, and irrevocably agrees to be bound by any judgment
rendered thereby in connection with this agreement. The Company hereby waives
any claim that Cook County Illinois is an inconvenient forum or an improper
forum based on lack of venue. The Company designates and appoints CT Corporation
System, Inc. (and such other persons as may hereafter be selected by the Company
with the consent of the Purchasers) to receive on its behalf, service of all
process in any such proceedings in any such court, such service being hereby
acknowledged by the Company to be effective and binding service in every
respect. A copy of such process so served shall be mailed by registered mail to
the Company at its address provided herein, except that unless otherwise
provided by applicable law, any failure to mail such copy shall not affect the
validity of service of process. To the extent permitted by Law, if any agent
appointed by the Company refuses to accept service, the Company hereby agrees
that service upon it by mail shall constitute sufficient notice. Nothing herein
shall affect the right to serve process in any other manner permitted by Law or
shall limit the right of any of the Purchasers to bring proceedings against the
Company in the courts of any other jurisdiction. To the extent provided by Law,
should the Company, after being so served, fail to appear or answer to any
summons, complaint, process or papers so served within the number of days
prescribed by Law after the mailing thereof, the Company shall be deemed in
default and an order and/or judgment may be entered by the court against the
Company as demanded or prayed for in such summons, complaint, process or papers.
The exclusive choice of forum for the Company set forth in this Section 8M shall
not be deemed to preclude the enforcement by the Purchasers of any judgment
obtained in any other forum or the taking by the Purchasers of any action to
enforce the same in any other appropriate jurisdiction, and the Company each
hereby waives the right to collaterally attack any such judgment or action.

                  8N. Waiver of Right to Jury Trial. The Company and its
Subsidiaries each on behalf of itself, its successors and assigns, hereby
waives, to the extent permitted by applicable Law, trial by jury in any
litigation in any court with respect to, in connection with, or arising out of
this Agreement, the Company's Articles of Incorporation or any other agreement
contemplated hereby or thereby or the validity, protection, interpretation,
collection or enforcement thereof. Notwithstanding anything contained in this
Agreement to the contrary, no claim may be made by the Company against the
Purchasers for any lost profits or any special, indirect or consequential
damages in respect of any breach or wrongful conduct (other than willful
misconduct constituting actual fraud) in connection with, arising out of or in
any way related this Agreement, to the transactions contemplated hereunder, the
Company's Articles of Incorporation or any act, omission or event occurring in
connection therewith; and the Company and its Subsidiaries each hereby waives,
releases and agrees not to sue upon any such claim for any such damages. The
Company and its subsidiaries each agrees that this Section 8N is a specific and
material aspect of this agreement and acknowledges that the purchaser would not
purchase the common stock hereunder if this Section 8N were not part of this
agreement.

                  8O. No Strict Construction. The parties hereto have
participated jointly in the negotiation and drafting of this Agreement. In the
event an ambiguity or question of intent or interpretation arises, this
Agreement shall be construed as if drafted jointly by the parties hereto, and no
presumption or burden of proof shall arise favoring or disfavoring any party by
virtue of the authorship of any of the provisions of this Agreement.

                  8P.      Complete Agreement.  This Agreement, those documents
expressly referred to herein and other documents of even date herewith, embody
the complete agreement and

                                      -35-

understanding among the parties and supersede any prior agreements or
representations by or among the parties, written or oral, which may have related
to the subject matter hereof in any way.

                  8Q.      No Third Party Beneficiaries.  This Agreement shall
not confer any rights or remedies upon any Person other than the parties hereto
and their respective successors and assigns, as specified herein and to the
extent explicitly set forth herein, the holders of Senior Indebtedness.

                  8R. Confidentiality of Information. Each of the Purchasers
shall use reasonable efforts, consistent with such Purchaser's customary
practices, to assure that information about the Company and its operations,
affairs and financial condition not generally disclosed to the public or to
trade and other creditors, which is furnished to such Purchaser pursuant to the
provisions hereof is used only for the purposes of this Agreement and shall not
be divulged to any Person other than their Affiliates and their respective
officers, directors, employees and agents, except: (a) to their attorneys and
accountants, (b) in connection with the enforcement of the rights of such
Purchaser hereunder or otherwise in connection with applicable litigation, (c)
in connection with the sale of securities so long as the prospective purchasers

were a "Purchaser"), (d) as may otherwise be required or requested by any
regulatory authority having jurisdiction over such Purchaser or by any
applicable law, rule, regulation or judicial process, reasonably believed by
such Purchaser to be binding on the Purchaser.

                  8S.      No Limitation.  No provision of this Agreement shall
be deemed or construed to limit, supersede or otherwise affect any provision of
any other agreement to which the Company and the Purchasers are a party,
including any provision of the First Purchase Agreement.

                  8T.      Restrictive Legend.  Each certificate representing
