                  THIS AMENDMENT NO. 2 to the Subscription Agreement (the

                  The Company, the Purchaser, the Fund and Co-Invest wish to
amend the Subscription Agreement to set forth certain rights and obligations
with respect to the shares of Common Stock purchased pursuant to the
Subscription Agreement.

                  Accordingly, in consideration of the mutual promises contained
herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

                  1. Amendments. Notwithstanding anything to the contrary
contained in the Subscription Agreement, as of the date hereof, the Subscription
Agreement is modified and amended as set forth below. All terms used in this
Amendment shall have the same definitions as set forth in the Subscription
Agreement unless otherwise indicated herein.

                  (A) Section 7 of the Subscription Agreement is hereby replaced
in its entirety by the following:

                  "7. Limitations on Transfer.

                      (a) General Restrictions on Transfer. The Purchaser agrees
that it shall not, either directly or indirectly, offer, sell, transfer, assign,
mortgage, hypothecate, pledge, create a security interest in or Lien upon,
encumber, donate, contribute, place in trust, or otherwise voluntarily or
involuntarily dispose of (any of the foregoing actions, to "Transfer" and, any
offer, sale, transfer, assignment, mortgage, hypothecation, pledge, security
interest or Lien, encumbrance, donation, contribution, placing in trust or other
disposition, a "Transfer") any Shares, or any interest therein, except pursuant
to a Permitted Transfer described in Section 7(c), unless such Transfer is made
in accordance with the applicable provisions of Sections 8, 9, 14 or 17.
   2
                                                                               2


                           (b) Void Transfers. Any attempt to Transfer any
Shares, or any interest therein, which is not in compliance with this Agreement
shall be null and void ab initio, and the Company shall not give any effect in
the Company's stock records to such attempted Transfer.

                           (c) Permitted Transfers. None of the restrictions
contained in this Agreement with respect to the Transfer of Shares (other than
those set forth in this Section 7(c) and in Section 7(d)) shall apply:

                                    (i) to any transfer by the Purchaser to any
         of its directors, officers, employees or Affiliates (as defined in the
         Partnership Agreement);

                                    (ii) to any transfer by the Purchaser in a
         Tag-Along Offer made in accordance with the applicable provisions of
         Section 8;

                                    (iii) to any transfer by the Purchaser
         pursuant to Section 9;

                                    (iv) to any transfer by the Purchaser
         pursuant to Section 14;

                                    (v) to any transfer by the Purchaser
         pursuant to the applicable provisions of Section 17; and

                                    (vi) to any transfer by the Purchaser of
         Shares for cash in a bona fide public offering (a "Registered
         Offering") pursuant to an effective registration statement under the
         Securities Act

Transfers made pursuant to this Section 7(c) are referred to herein as
"Permitted Transfers" and transferees taking under a Permitted Transfer are
referred to herein as "Permitted Transferees." Transferees taking under a
Permitted Transfer described in Section 7(c)(i) are referred to herein as
"Related Transferees."

         (d) Registration of Transfer by Company. No transfer of Shares by the
Purchaser (other than transfers of Shares pursuant to a Registered Offering
permitted under Section 7(c)(vi)) shall be effective (and the Company shall not
transfer on its books any such Shares) unless

                  (i) the certificates representing such Shares issued to the
         Permitted Transferee shall bear any legends required by Section 18;

                  (ii) the Permitted Transferee (if not already a party hereto)
         agrees in writing to be bound by the terms and conditions of this
         Agreement;
   3
                                                                               3


                  (iii) such transfer is exempt from registration under the
         Securities Act and the Company, should it so request, has received a
         written legal opinion of counsel to the Purchaser satisfactory to its
         counsel that the proposed transfer is exempt from such registration;
         and

                  (iv) such transfer complies with the other provisions of this
         Agreement.

                  (e) Legend. In the event that any Shares become free of the
rights and restrictions imposed by this Agreement, the Purchaser shall be
entitled to receive, promptly upon presentment to the Company of the certificate
or certificates evidencing the same, a new certificate or certificates not
bearing the restrictive legend provided for in the second paragraph of Section
18. In the event that any Shares are (i) transferred in connection with a
Registered Offering, or (ii) transferred pursuant to an exemption from
registration under the Securities Act and the Company has received a written
legal opinion of counsel to the Purchaser satisfactory to its counsel (A) as to
the availability of and the compliance with such exemption and (B) that such
shares need not bear the restrictive legend set forth in the first paragraph of
Section 18 hereof, the Company shall issue a new certificate or certificates
representing such securities not bearing such legend."

         (B) Section 9(a) of the Subscription Agreement is hereby replaced in
its entirety by the following:

                  "(a) In the event that one or more Selling Stockholders
holding at least 40% of the outstanding shares of Common Stock receives a bona
fide offer from a Third Party Purchaser (excluding offers from affiliates of any
of the holders of Common Stock (each a "Stockholder")) to purchase (including a
purchase by merger) at least a majority of the outstanding shares of Common
Stock, the Selling Stockholders may send written notice (a "Buyout Notice") to
the Purchaser notifying the Purchaser that it will be required to sell the same
percentage of its shares of Common Stock in such sale as the Selling
Stockholders propose to sell (which percentage shall be specified in such Buyout
Notice) (the "Designated Percentage")."

         (C) Section 11 of the Subscription Agreement is hereby amended by
appending the following sentence to the end of Section 11:

                  "Notwithstanding anything to the contrary in the Registration
Rights Agreement, neither the Company, the Fund nor Co-Invest shall agree to any
amendment, modification or supplement of the Registration Rights Agreement or
any waiver or consent to or departure from the provisions thereof which
materially and adversely affects any right of the Purchaser, without the prior
written consent of the Purchaser."

                                                                               4


                  (D) Section 12 of the Subscription Agreement is hereby
replaced in its entirety by the following:

                  "12. Governance. (a) The Purchaser shall be entitled to
designate one of the members of the Company's Board of Directors (the "Purchaser
Director"); provided that if the Purchaser directly owns less than 25% of the
Shares, as adjusted for any stock-splits, stock dividends or other similar
changes in the capital structure of the Company, the Purchaser Director shall
resign from the Company's Board of Directors and the Purchaser shall no longer
have the right to designate a director. Each year, the Purchaser Director shall
have the right to bring to one meeting of the Company's Board of Directors one
observer designated by the Purchaser. The Company shall pay all reasonable costs
incurred by the Purchaser Director in attending meetings of the Company's Board
of Directors upon presentation to the Company of expense statements or vouchers
or such other supporting information as the Company shall require from its
directors.

                           (b) Composition and Election of Board of Directors.

                               (i) The Board of Directors of the Company shall
         initially consist of 12 members (collectively, the "Directors" and
         each, individually, a "Director"), who shall be John M. Cuthbert,
         Oliver C. Boileau, Jr., Stephen Eisenstein, Donald Glickman, John F.
         Lehman, Keith Oster, William Paul, Thomas G. Pownall, George Sawyer,
         Joseph Stroud, Thomas F. Treinen and Jack B. Watson. The Fund shall be
         entitled to designate all of the Directors of the Company other than
         the Person designated by the Purchaser pursuant to Section 12(a).

                               (ii) The Purchaser agrees to vote all shares of
         Common Stock now or hereafter owned by it (or over which it exercises
         voting power pursuant to a valid proxy or otherwise), to cause each of
         its Affiliates to vote all shares of Common Stock now or hereafter
         owned by it (or over which it exercises voting power pursuant to a
         valid proxy or otherwise) and otherwise to use its reasonable best
         efforts, to:

                                    (A) elect as Directors the persons
                           designated by the Fund in accordance with Section
                           12(b)(i);

                                    (B) remove, with or without cause, (x) any
                           Director designated by the Fund in accordance with
                           Section 12(b)(i), if requested by the Fund and (y)
                           any Purchaser Director once the Purchaser ceases to
                           own at least twenty-five percent (25%) of the Shares;
                           and

                                    (C) cause any vacancy on the Board of
                           Directors of the Company created by the death,
                           resignation, incapacity

                  any Director designated by the Fund in accordance with Section
                  12(b)(i), to be filled by a replacement Director designated by
                  the Fund."

                  (E) Section 16(k) of the Subscription Agreement is hereby
replaced in its entirety by the following:

                           "(k)     Termination

                           (i) Termination as to Shares. This Agreement shall
         terminate with respect to any particular Shares when such Shares shall
         have been sold in a Registered Offering or distributed to the public
         pursuant to Rule 144 under the Securities Act.

                           (ii) Termination of Agreement. This Agreement shall
         terminate and there shall be no liability or obligation on the part of
         any party or its affiliates, directors, officers or stockholders with
         respect to this Agreement upon the earliest to occur of (1) the
         Purchaser and its Affiliates having ceased to beneficially own any
         Shares, (2) the sale of shares of Common Stock at an aggregate offering
         price of at least $40,000,000 in a Registered Offering, (3) the tenth
         anniversary of this Agreement and (4) February 19, 1999 if the Merger
         has not been consummated on or before February 19, 1999; provided,
         however, that the provisions of this Agreement shall continue in effect
         for the purpose of enforcing against any party hereto all obligations
         and undertakings that shall have theretofore become operative;
         provided, further, however, that, in connection with a termination
         pursuant to clause (1) above, the provisions of this Agreement shall be
         binding upon any transferee of the Purchaser or its Affiliates, whether
         such transfer was pursuant to a Permitted Transfer (other than a
         Registered Offering) or otherwise. Notwithstanding the foregoing, the
         benefits of this Agreement shall inure only to a Permitted Transferee
         of the Purchaser.

                  (F) The following shall be added to the Subscription Agreement
in its entirety as Section 17:

                  "17.     Right of First Offer.

                           (a) First Offer Notice. If the Purchaser, the Fund or
Co-Invest desire to transfer any shares of Common Stock other than pursuant to
a Permitted Transfer (each party desiring to make such a transfer an "Offeror
Stockholder"), the Offeror Stockholder shall, prior to soliciting a bona fide
written offer from an independent third-party (the "Third-Party Offer"), deliver
a written notice (the "First Offer Notice") offering to sell the shares of
Common Stock proposed to be sold ("Offered Securities") to the Purchaser, the
other stockholders of the Company who enter into the Stockholders Agreement (as
described in Section 17(e)) (the "Other Stockholders") and all other persons
that acquire any shares of Common Stock that agree to be bound by the terms of
this Agreement or such Stockholders Agreement in accordance with the terms or
removal of 
   6
                                                                               6


and provisions hereof or thereof (together with the Purchaser and the Other
Stockholders, the "Offeree Stockholders") or to the Company. The First Offer
Notice shall state (i) that the Offeror Stockholder desires to sell the Offered
Securities and (ii) the purchase price per share and other material terms on
which and the material conditions subject to which the Offered Securities are
offered; provided, however that this Section 17 shall not apply to any shares of
Common Stock with respect to which a first offer notice has been delivered to
the Offeree Stockholders on substantially similar terms to this Agreement; and
provided, further, that this Section 17 shall terminate and there shall be no
liability or obligation on the part of any party or its affiliates, directors,
officers or stockholders with respect to this Section 17 upon the termination of
the Stockholders Agreement.

                           (b) Exercise of Right of First Offer.

                               (i) Upon receipt of the First Offer Notice, each
         Offeree Stockholder shall have the option (the "Stockholders' Right of
         First Offer"), which shall be exercisable by written notice (the
         "Notice of Election") delivered to the Offeror Stockholder within ten
         (10) days after the date of the First Offer Notice (the "Stockholders'
         First Offer Option Period"), to purchase from the Offeror Stockholder,
         at the price and upon the terms specified in the First Offer Notice, a
         number of Securities up to the sum of (A) the number of shares of
         Common Stock included in the Offered Securities multiplied by a
         fraction, the numerator of which is the number of shares of Common
         Stock owned by such Offeree Stockholder and the denominator of which is
         the number of shares of Common Stock held by all Offeree Stockholders
         and (B) the number of shares of Common Stock that, under the formula in
         clause (A), all Offeree Stockholders could have elected to purchase but
         did not so elect, multiplied by a fraction, the numerator of which is
         the number of shares of Common Stock owned by such Offeree Stockholder
         and the denominator of which is the total number of shares of Common
         Stock owned by the Offeree Stockholders (including such Offeree
         Stockholder) that exercised the option provided herein. Each Offeree
         Stockholder who desires to exercise its option to purchase Offered
         Securities shall state in its Notice of Election the number of shares
         of Common Stock that such Offeree Stockholder proposes to purchase
         determined in accordance with clause (b)(i)(A) plus an amount of
         additional shares of Common Stock, if any, that such Offeree
         Stockholder would be willing to purchase from the Offeror Stockholder
         in the event that one or more Offeree Stockholders (other than such
         Offeree Stockholder) elect not to exercise their Stockholders' Right of
         First Offer, in whole or in part. If any Offeree Stockholder shall fail
         to deliver the Notice of Election within the Stockholders' First Offer
         Option Period, such failure shall be deemed an election not to purchase
         any Offered Securities subject to the Stockholders' Right of First
         Offer and such Stockholders' Right of First Offer shall thereupon
         expire with respect to the Offered Securities only.

                               (ii) If the number of shares of Common Stock with
         respect to which the Stockholders' Right of First Offer has been
         exercised is less
   7
                                                                               7


         than the number of Offered Securities, the Company shall have the
         option (the "Company's Right of First Offer"), which shall be
         exercisable by written notice delivered to the Offeror Stockholder
         within five (5) days after the expiration of the Stockholders' First
         Offer Option Period (the "Company's First Offer Option Period"), to
         purchase any or all of the Offered Securities not purchased by the
         Offeree Stockholders at the price and upon the terms specified in the
         First Offer Notice. If the Company shall fail to deliver a notice (the
         "Company Notice") of its election to exercise the Company's Right of
         First Offer within the Company First Offer Option Period, such failure
         shall be deemed an election not to purchase any Offered Securities
         subject to the Company's Right of First Offer and the Company's Right
         of First Offer shall thereupon expire with respect to the Offered
         Securities only.

                               (iii) The Stockholders' Right of First Offer and
         the Company's Right of First Offer shall be exercisable only if the
         Offeree Stockholders and/or the Company, in the aggregate, elect to
         purchase all, and not less than all, of the Offered Securities. Each
         Notice of Election and Company Notice shall recite that such Notice of
         Election or Company Notice, as the case may be, constitutes a binding
         obligation of the Offeree Stockholder or the Company, as the case may
         be, submitting same to purchase, upon the same terms and subject to the
         same conditions as the Third-Party Offer, up to the number of shares of
         Common Stock set forth in the Notice of Election or the Company Notice,
         as the case may be.

                               (iv) The closing of the purchase of the Offered
         Securities subscribed to by the Offeree Stockholders and the Company
         pursuant to this Article 4 shall be held at the principal office of the
         Company at 10:00 a.m., local time not later than the thirtieth (30th)
         day after the Company First Offer Option Period shall have expired.

                      (c)      Sale to Third-Party Purchaser.

                               (i) If the First Offer Notice shall have been
         duly delivered, and the Offeree Stockholders and the Company together
         shall not have exercised the Stockholders' Right of First Offer and the
         Company's Right of First Offer to purchase all of the Offered
         Securities, the Offeror Stockholder may solicit Third-Party Offers to
         purchase all (but not less than all) of the Offered Securities and, so
         long as any sale of the Offered Securities made pursuant to a Third
         Party Offer that is (A) upon such terms, including price, and subject
         to such conditions as are, in the aggregate, no less favorable to the
         Offeror Stockholder than those set forth in the First Offer Notice;
         provided, however, that the price may be not less than 90% of the price
         set forth in the First Offer Notice (B) bona fide, (C) consummated
         within one hundred eighty (180) days from the expiration date of the
         Company First Offer Option Period, (D) if applicable, subject to any
         Tag-Along Right and (E) in accordance with clause (ii) below, such
         transfer may be
   8
                                                                               8



         consummated without further restriction under this Article 17 and shall
         be a Permitted Transfer under this Agreement.

                               (ii) Offered Securities transferred by the
         Purchaser in accordance with clause (i) above shall remain, and the
         third-party purchaser shall agree to take and hold such Offered
         Securities, subject to all of the obligations and restrictions imposed
         upon the Purchaser by this Agreement. No transfer of Offered Securities
         to which the preceding sentence applies shall be effective unless and
         until the third-party purchaser shall have executed and delivered to
         the Company an appropriate instrument to the foregoing effect.

                           (d) Involuntary Transfers.

                               (i) If an Involuntary Transfer of any shares of
         Common Stock (the "Transferred Securities") owned by the Offeror
         Stockholder shall occur, each of the other stockholders of the Company
         shall have the same rights as specified in Sections 17(a) and (b) with
         respect to such Transferred Securities as if the Involuntary Transfer
         had been a proposed voluntary transfer by the Offeror Stockholder,
         except that (a) the Stockholders First Offer Option Period shall run
         from the date of receipt by the Company and such Stockholders of notice
         of the Involuntary Transfer, (b) the closing date of the sale shall be
         90 days after the expiration of the Company's First Offer Option
         Period, (c) such rights shall be exercised by notice to the transferee
         of such Transferred Securities (the "Involuntary Transferee") rather
         than to the Offeror Stockholder and (d) the purchase price per
         Transferred Security shall be agreed to between the Involuntary
         Transferee and the Offeree Stockholders; provided however, that if such
         parties fail to agree as to such purchase price, the purchase price
         shall be the fair market value thereof as determined in accordance with
         paragraph (ii) below.

                               (ii) The fair market value of the Transferred
         Securities shall be determined by a panel of three independent
         appraisers, which shall be recognized investment banking firms or
         recognized experts experienced in the evaluation of corporations.
         Within fifteen (15) days after the notice to the Involuntary Transferee
         with respect to the exercise of the right to purchase the Transferred
         Securities, the Involuntary Transferee and the Board of Directors of
         the Company shall each designate one such appraiser that is willing and
         able to conduct such determination. If either of the Involuntary
         Transferee or the Board of Directors of the Company fails to make such
         designation within such period, the other party that has made the
         designation shall have the right to make the designation on its behalf.
         The two appraisers designated shall, within a period of fifteen (15)
         days after the designation of the second appraiser, agree to designate
         a third appraiser. The three appraisers shall conduct their
         determination as promptly as practicable, and the fair market value of
         the Transferred Securities shall be the average of the determination of
         the two appraisers that are closer to each other than to the
         determination of the third appraiser, which third

                                                                               9


         determination shall be discarded. Such determination shall be final and
         binding on the Involuntary Transferee and the Offeree Stockholders and
         the Company. The Involuntary Transferee shall be responsible for the
         fees and expenses of the appraiser designated by or on behalf of it and
         the Offeree Stockholders and the Company shall be responsible for the
         fees and expenses of the appraiser designated by or on behalf of the
         Board. The Involuntary Transferee and the Offeree Stockholders and the
         Company shall each share half of the fees and expenses of the third
         party appraiser designated by the other appraisers.

                               (iii) The closing of any purchase under this
         paragraph (d) shall be held at the principal office of the Company at
         10:00 o'clock A.M., local time, on the designated closing date or such
         other time and place as the parties to the transaction may agree.

                               (iv) In the event any of the provisions of this
         paragraph (d) shall be held to be unenforceable with respect to any
         particular Involuntary Transfer, the Offeree Stockholders and the
         Company shall have the rights specified in this Section 17 with respect
         to any transfer by an Involuntary Transferee and each Stockholder
         agrees that any Involuntary Transfer shall be subject to such rights,
         in which case the Involuntary Transferee shall be deemed to be the
         Offeror Stockholder for purposes of this Section 17 of this Agreement
         and shall be bound by the provisions of this Section 17 and the other
         provisions of this Agreement. If an Involuntary Transfer of any shares
         of Common Stock owned by the Offeror Stockholder shall occur prior to
         the termination of this Agreement, such transferee in the Involuntary
         Transfer (and each of its transferees) shall have none of the rights of
         the Offeror Stockholder under this Agreement unless and until it
         complies with the provisions of Section 7(c).

                               (v) For the purposes of this Section 17,
         Involuntary Transfer means any Transfer, proceeding or action by or in
         which a Stockholder shall be deprived or divested of any right, title
         or interest in or to any of the shares of Common Stock owned by the
         Offeror Stockholder, including, without limitation, any seizure under
         levy of attachment or execution, any transfer, in connection with
         bankruptcy (whether pursuant to the filing of a voluntary or
         involuntary petition under the United States Bankruptcy Code of 1978,
         or any amendments thereto) or other court proceeding to a debtor in
         possession, trustee in bankruptcy or receiver or other officer or
         agency, any transfer to a state or to a public officer or agency
         pursuant to any statute pertaining to escheat or abandoned property and
         any transfer pursuant to a final decree of a court in a divorce action.

                           (e) The Company, the Fund and Co-Invest shall use
their best efforts to enter into a Stockholders Agreement (the "Stockholders
Agreement"), with the Treinen Family Trust and the Neubauer Family Trust in
which the Company, the Fund, Co-Invest, the Treinen Family Trust and the
Neubauer Family Trust agree to grant the
