for any registration or transfer of Warrant Certificates which are registered or
to be registered in the name of a fiduciary or the nominee of a fiduciary unless
made with the actual knowledge that a fiduciary or nominee is committing a
breach of trust in requesting such registration or transfer, or with knowledge
of such facts that the Company's participation therein amounts to bad faith.

         4.       Transfer of Warrant Certificate.
                  -------------------------------

                  and any rights to the further issuance of Warrants pursuant
                  hereto may only be transferred together with the Notes on a
                  pro rata basis (as to each tranche of Base Warrants and
                  Additional Warrants issued or issuable) in proportion to the
                  principal amount of Notes issued to each Purchaser. After the
                  earlier of a Prepayment Event or the fourth (4th) anniversary
                  of the date hereof, the Warrants may be transferred
                  independent of the Notes, provided such transfer is in
                  accordance with the terms hereof. The Warrant Certificate
                  shall be transferable only on the Warrant Register upon
                  delivery of the Warrant Certificate duly endorsed by the
                  Holder or by its duly authorized attorney or representative
                  (with evidence reasonably satisfactory to the Company of such
                  authorization), or accompanied by evidence reasonably
                  satisfactory to the Company of succession, assignment or
                  authority to transfer. Notwithstanding the foregoing, the
                  Company shall have no obligation to cause Warrant Certificates
                  to be transferred on the Warrant Register to any person,
                  unless the Holder of such Warrants shall furnish to the
                  Company evidence satisfactory to the Company of (i) (x)
                  compliance with the registration provisions of Section 5 of
                  the Securities Act of 1933, as amended (the "Act"), or (y) the
                  availability of an exemption from compliance with the
                  registration provisions of Section 5 of the Act; and (ii)
                  compliance with that certain Amended and Restated
                  Stockholders' Agreement to be executed by or on behalf of the
                  parties hereto on the Closing Date (the "Amended and Restated
                  Stockholders' Agreement").

                  notwithstanding subsection (a) above, that this Agreement does
                  not restrict transfers of Warrants among the Purchasers to the
                  extent otherwise permitted under the Indemnification and
                  Contribution Agreement dated the date hereof among the
                  Purchasers.

                           (a) In the event a Prepayment Event occurs (i) prior

                  event of an IPO (as defined in the Note Purchase Agreement),
                  the Prepayment Event Price shall be the price per share of
                  Common Stock offered pursuant to the IPO. In the event of a
                  Change in Control (as defined in the Note Purchase Agreement),

                  event of an Asset Sale (as defined in the Note Purchase
                  Agreement), the Prepayment Event Price shall be the price
                  reasonably and in good faith determined by the Board of
                  Directors as the per share valuation of the company based on
                  the arms length negotiations with the acquiring entity
                  (determined on a basis taking into account all options,
                  warrants, convertible securities and similar securities then

                  subject to subsection (d) below.

                           (d) In the event the Holders of a majority of the
                  then outstanding Warrants (the "Requisite Holders") provide
                  written notice to the Company within ten (10) days of receipt
                  of written notice of the Prepayment Event Price set by the
                  Company of their objection to such price, the Prepayment Event
                  Price shall be determined as follows: (i) by agreement among
                  the Company and the Requisite Holders within ten (10) days
                  following the event requiring such determination or (ii) in
                  the absence of such an agreement, by an Independent Financial
                  Expert selected in accordance with the further provisions of
                  this definition. If required, an Independent Financial Expert
                  shall be selected within five (5) days following the
                  expiration of the ten (10) day period referred to above,
                  either by agreement among the Company and the Requisite
                  Holders or, in the absence of such agreement, by lot from a
                  list of four potential Independent Financial Experts remaining
                  after the Company nominates three, the Requisite Holders
                  nominate three, and each side eliminates one potential
                  Independent Financial Expert. The Independent Financial Expert
                  shall be instructed by the Company and the Requisite Holders
                  to make its determination within 20 days of its selection. The
                  fees and expenses of an Independent Financial Expert selected
                  hereunder shall be borne equally by the Company and by the
                  Holders (on a PRO RATA basis based on the number of Warrants
                  held by each Holder) participating in the transaction to which
                  the determination relates.

                  Agreement, in respect of any fraction of a share of such stock
                  otherwise issuable upon such exercise. Except under
                  circumstances described in the following sentence, the shares
                  of Warrant Stock purchased pursuant to the immediately
                  preceding sentence shall be deemed to be issued to the Holder
                  as the record owner of such shares as of the close of business
                  on the Exercise Date. Notwithstanding the foregoing, if the
                  Company determines, on or after the date of exercise of any
                  Warrant, that issuance of the Warrant Stock represented
                  thereby would violate an applicable order, law, rule, or
                  regulation, including federal or state securities laws, the
                  Company shall so notify immediately the exercising Holder and
                  shall in good faith, and as expeditiously as possible,
                  endeavor to issue the Warrant Stock without such violation.
                  The right of purchase represented by the Warrants shall be
                  exercisable, at the election of the Holder thereof, either in
                  full or from time to time in part and, in the event that any
                  Warrant is exercised in respect of less than all of the shares
                  of Warrant Stock purchasable on such exercise at any time
                  prior to the Expiration Date, a new Warrant Certificate
                  evidencing the remaining Warrants shall be issued.

         6. PAYMENT OF TAXES. The Company shall pay all documentary stamp taxes,
if any, attributable to the initial issuance of Warrant Stock upon the exercise
of Warrants PROVIDED, HOWEVER, that the Company shall not be required to pay any
tax or taxes which may be payable in respect of any permitted transfer involved
in the issue or delivery of any Warrant Certificates or Warrant Stock in a name
other than that of the registered Holder of such Warrants.

         7. MUTILATED OR MISSING WARRANTS. Upon (i) receipt by the Company of
evidence reasonably satisfactory to it of the loss, theft, destruction or
mutilation of a Warrant Certificate, (ii) if requested by the Company, the
posting of a bond in an amount equal to the value of the lost, stolen or
destroyed Warrant Certificate, (iii) reimbursement to the Company of all
reasonable expenses incident thereto, and (iv) surrender and cancellation of
such Warrant Certificate, if mutilated, the Company will make and deliver in
lieu of such Warrant Certificate a new Warrant Certificate of like tenor and
representing an equivalent right or interest. The term "outstanding" when used
herein with reference to the Warrant Certificate as of any particular time shall
not include any Warrant Certificate in lieu of which a new Warrant Certificate
has been made and delivered by the Company in accordance with the provisions
hereof.

         8. CAPITALIZATION OF THE COMPANY. Without giving effect to the Warrants
contemplated herein, the authorized capital stock of the Company is as set forth
in Schedule 3.1 to the Note Purchase Agreement.

         9.       Reservation Of Warrant Stock.
                  ----------------------------

                           (a) The Company represents that there has been
                  reserved out of the authorized and unissued shares of Common
                  Stock, a number of shares sufficient to provide for the
                  exercise of the right of purchase represented by the Warrant
                  Certificates as initially issued, and the Company, which
                  currently acts as the transfer agent for its Common Stock
                  ("Transfer Agent") and every subsequent Transfer Agent for any
                  shares of the Company's capital stock issuable upon the
                  exercise of any of the Warrants are hereby irrevocably
                  authorized and directed at all times until the Expiration Date
                  or earlier termination of this Agreement to reserve such
                  number of authorized and unissued shares of Common Stock as
                  shall be required for such purpose. The Company will keep a
                  copy of this Agreement on file with every subsequent Transfer
                  Agent for any shares of the Company's capital stock issuable
                  upon the exercise of the Warrants. The Company will supply any
                  such subsequent Transfer Agent with duly executed stock
                  certificates for issuance on exercise of Warrants and will
                  itself provide or make available any cash which may be
                  required by Section 11 of this Agreement. The Company will
                  furnish to any such subsequent Transfer Agent a copy of all
                  notices of adjustments, and certificates related thereto,
                  transmitted to each Holder pursuant to Section 10.3 of this
                  Agreement. All Warrant Certificates surrendered in the
                  exercise of the rights thereby evidenced shall be cancelled.

                           (b) The Company covenants that it shall endeavor to
                  comply with all securities laws regulating the offer and
                  delivery of shares of Common Stock upon exercise of the
                  Warrants; and that if any shares of Common Stock required to
                  be reserved for purposes of exercising the Warrants hereunder
                  require registration with or approval of any governmental
                  authority under any Federal or state law before such shares
                  may be validly issued or delivered upon exercise of the
                  Warrants, the Company shall, in good faith and as
                  expeditiously as possible, endeavor to secure such
                  registration or approval, as the case may be. The Company
                  covenants that all shares of Common Stock which shall be
                  issued upon exercise of the Warrants shall upon issue and
                  payment therefor be validly issued, fully paid and
                  nonassessable.

         10. ADJUSTMENTS OF WARRANT PRICE, PREPAYMENT EVENT PRICE AND NUMBER OF
SHARES OF WARRANT STOCK. The number and kind of securities purchasable upon the
exercise of each Warrant and the Warrant Price related thereto shall be subject
to adjustment from time to time upon the happening of certain events, as
hereinafter defined, but (with respect to Warrants) only as to Warrants
outstanding at the time of such adjustment. Upon each adjustment of the Warrant
Price pursuant to the provisions of Section 10.1(b), the Holder of such Warrant
shall thereafter, prior to the Expiration Date thereof, be entitled to purchase
at the Warrant Price resulting from such

                                        8

adjustment, the number of shares of Warrant Stock obtained by multiplying the
Warrant Price in effect immediately prior to such adjustment by the number of
shares of Warrant Stock issuable upon exercise of such Warrant immediately prior
to such adjustment and dividing the product thereof by the Warrant Price
resulting from such adjustment.

                  10.1 ADJUSTMENT OF THE NUMBER OF SHARES OF WARRANT STOCK AND
         THE WARRANT PRICE. The number of shares of Warrant Stock and the
         Warrant Price shall be subject to adjustment as follows:

                           (a) In case the Company shall at any time after the
                  date of issuance of a Warrant (A) pay a dividend or make a
                  distribution on its Common Stock in shares of its capital
                  stock (whether in shares of Common Stock or of capital stock
                  of any other class), (B) subdivide its outstanding shares of
                  Common Stock into a greater number of shares, (C) combine its
                  outstanding shares of Common Stock into a smaller number of
                  shares, or (D) reclassify, reorganize or effect any similar
                  transaction with respect to any of its shares of Common Stock,
                  or in substitution or exchange therefor (other than a change
                  in par value, or from par value to no par value, or from no
                  par value to par value), then the number and, if applicable,
                  kind of shares of Warrant Stock to be received by any Holder
                  shall be adjusted so that the Holder will be entitled to
                  receive on exercise the number and kind of shares of capital
                  stock which it would have owned immediately following such
                  action had its Warrants been exercised immediately prior
                  thereto. An adjustment made pursuant to this subsection (a)
                  shall become effective immediately after the payment date in
                  the case of a dividend or distribution and shall become
                  effective immediately after the effective date in the case of
                  a subdivision, combination, reclassification, reorganization
                  or similar transaction. If, as a result of an adjustment made
                  pursuant to this subsection (a), a Holder shall become
                  entitled to receive shares of two or more classes of capital
                  stock of the Company, the Board of Directors or a duly
                  authorized committee thereof shall in good faith determine
                  (which determination shall be conclusive and binding) the
                  allocation of the Warrant Price between or among shares of
                  such classes of capital stock. After such allocation, the
                  Warrant Price and number of shares of each class of capital
                  stock that is part of the Warrant Stock shall thereafter be
                  subject to adjustment in a manner and on terms determined by
                  the Board of Directors (which determination shall be
                  conclusive and binding) to be as nearly equivalent as
                  practicable to those applicable to Common Stock under this
                  Section 10.

                           (b) (i) From the date hereof to and including the
                           second anniversary of the date hereof, if the Company
                           shall issue any shares of Common Stock other than
                           Excluded Shares (as hereinafter defined) for
                           consideration per share (the "Issuance Price") less
                           than the Warrant Price (as hereinafter defined) per
                           share in effect immediately prior to such issuance,
                           the Warrant Price in effect immediately prior to such
                           issuance shall be reduced (but shall not be
                           increased) to the Issuance Price.

<PAGE>   11



                                 (ii) After the second anniversary of the date
                           hereof, if the Company shall issue any shares of
                           Common Stock other than Excluded Shares for
                           consideration per share less than the Warrant Price
                           per share in effect immediately prior to such
                           issuance, the Warrant Price in effect immediately
                           prior to such issuance shall be reduced (but shall
                           not be increased) to the price (calculated to the
                           nearest cent) determined: by dividing (A) an amount
                           equal to the sum of (1) the number of shares of
                           Common Stock outstanding on a fully diluted basis
                           immediately prior to such issuance multiplied by the
                           Warrant Price per share in effect immediately prior
                           to such issuance and (2) the consideration, if any,
                           received by the Company upon such issuance by (B) the
                           number of shares of Common Stock outstanding on a
                           fully diluted basis immediately after such issuance.

                           (c) CERTAIN ADJUSTMENT FACTORS. For the purposes of
                  any adjustment of the Warrant Price pursuant to paragraph (b)
                  above, the following provisions shall be applicable:

                           (x) CASH. In the case of the issuance of shares of
                  Common Stock for cash, the amount of the consideration
                  received by the Company shall be deemed to be the amount of
                  the cash proceeds received by the Company for such shares of
                  Common Stock before deducting therefrom any discounts,
                  commissions, taxes or other expenses allowed, paid or incurred
                  by the Company for any underwriting or otherwise in connection
                  with the issuance and sale thereof; and

                           (y) CONSIDERATION OTHER THAN CASH. In the case of the
                  issuance of shares of Common Stock (other than upon the
                  conversion of shares of capital stock or other securities of
                  the Company) for consideration in whole or in part other than
                  cash, including securities acquired in exchange therefor
                  (other than securities by their terms so exchangeable), the
                  consideration other than cash shall be deemed to be the fair
                  value thereof (as determined by the Board of Directors of the
                  Company based on an opinion of an outside financial advisor of
                  recognized regional or national standing, which may, but need
                  not, be the independent public accountants who serve as the
                  regular auditors of the Company (the "Financial Advisor"),
                  whose determination shall be conclusive and binding),
                  irrespective of any accounting treatment; and

                           (z) OPTIONS AND CONVERTIBLE SECURITIES. In the case
                  of the issuance of (i) options, warrants or other rights to
                  purchase or acquire shares of Common Stock (whether or not
                  exercisable immediately following such issuance), (ii)
                  securities by their terms convertible into or exchangeable for
                  shares Common Stock (whether or not so convertible or
                  exchangeable immediately following such issuance), or (iii)
                  options, warrants or rights to purchase such convertible or
                  exchangeable securities (whether or not exercisable
                  immediately following such issuance):

                                    (1) the aggregate maximum number of shares
                           of Common Stock deliverable upon exercise of such
                           options, warrants or other rights to purchase or
                           acquire shares of Common Stock shall be deemed to
                           have been issued at the time such options, warrants
                           or other rights are first issued and for a
                           consideration equal to the consideration (determined
                           in the manner provided in clauses (x) and (y) above),
                           if any, received by the Company upon the issuance of
                           such options, warrants or other rights plus the
                           purchase price provided in such options, warrants or
                           other rights for the shares of Common Stock covered
                           thereby (if the purchase price per share of Common
                           Stock is expressed as a range, the purchase price per
                           share for purposes of this subparagraph (z)(1) shall
                           be the average of such range of prices);

                                    (2) the aggregate maximum number of shares
                           of Common Stock deliverable upon conversion of or in
                           exchange for any such convertible or exchangeable
                           securities, or upon the exercise of options, warrants
                           or other rights to purchase or acquire such
                           convertible or exchangeable securities and the
                           subsequent conversion or exchange thereto shall be
                           deemed to have been issued at the time such
                           convertible or exchangeable securities or such
                           options, warrants or other rights are first issued
                           and for a consideration equal to the consideration,
                           if any, received by the Company for any such
                           convertible or exchangeable securities or options,
                           warrants or other rights (excluding any cash received
                           on account of accrued interest or accumulated
                           dividends), plus the additional consideration, if
                           any, to be received by the Company upon the
                           conversion or exchange of such securities and the
                           exercise of any options, warrants or other rights
                           (the consideration in each case to be determined in
                           the manner provided in clauses (x) and (y) above);

                                    (3) on any change in the number of shares of
                           Common Stock deliverable upon exercise of any such
                           options, warrants or other rights which have become
                           exercisable or conversion of or exchange of such
                           convertible or exchangeable securities which have
                           become convertible or exchangeable, or any change in
                           the consideration to be received by the Company upon
                           such exercise, conversion or exchange, the Warrant
                           Price as then in effect shall forthwith be readjusted
                           to such Warrant Price as would have been obtained had
                           such adjustment been made upon the original issuance
                           of such options, warrants or other rights; provided,
                           however, no adjustment shall be made with respect to
                           such options, warrants or other rights exercised
                           prior to such change, or securities converted or
                           exchanged prior to such change;

                                    (4) on the expiration or cancellation of any
                           such options, warrants or other rights, or the
                           termination of the right to convert or exchange such
                           convertible or exchangeable securities, if the
                           Warrant Price shall have been adjusted upon such
                           securities being issued or becoming exercisable,
                           convertible or exchangeable, such Warrant Price shall
                           forthwith be readjusted

                           to such Warrant Price as would have been obtained had
                           an adjustment been made on the basis of the issuance
                           of only the number of shares of Common Stock actually
                           issued upon the exercise of such options, warrants or
                           other rights, or upon the conversion or exchange of
                           such securities; and

                                    (5) if the Warrant Price shall have been
                           adjusted when such options, warrants or other rights
                           were first issued or such convertible or exchangeable
                           securities were first issued, no further adjustment
                           of the Warrant Price shall be made for the actual
                           issuance of shares of Common Stock upon the exercise,
                           conversion or exchange thereof.

                           (d) EXCLUDED SHARES. "Excluded Shares" shall mean (i)
                  any shares of Common Stock issued in a transaction described
                  in Section 10.1(a) of this Agreement; and (ii) issuances of
                  shares of Common Stock from time to time pursuant to stock
                  option or bonus plans authorized by the Board of Directors of
                  the Company as of the date hereof; (iii) issuances of Common
                  Stock, or warrants, options or rights to acquire shares of
                  Common Stock, or securities convertible into or exchangeable
                  for Common Stock pursuant to the terms of any acquisition by
                  the Company of all or substantially all of the operating
                  assets, or more than fifty percent (50%) of the voting capital
                  stock or other management interest of any business entity in a
                  transaction negotiated on an arms'-length basis and expressly
                  approved in advance by the Board of Directors of the Company;
                  (iv) issuances of shares of Common Stock from time to time
                  upon the exercise, exchange or conversion of warrants,
                  options, convertible securities, the Notes (whether or not
                  outstanding as of the date hereof) or other securities
                  outstanding as of the date hereof; and (v) issuances of shares
                  of Common Stock from time to time pursuant to the
                  anti-dilution provisions of other securities.

                           (e) No adjustment in the Warrant Price shall be
                  required unless such adjustment would require an increase or
                  decrease of at least 2.2% in such price; PROVIDED, HOWEVER,
                  that any adjustments which by reason of this subsection (f)
                  are not required to be made shall be carried forward and taken
                  into account in any subsequent adjustment. All calculations
                  under this Section 10.1 shall be made to the nearest tenth of
                  a cent or to the nearest one-hundredth of a share, as the case
                  may be.

                           (f) The number of shares of Common Stock outstanding
                  at any given time shall not include shares owned or held by or
                  for the account of the Company, and the disposition of any
                  such shares shall be considered an issuance of Common Stock
                  for the purposes of this Section 10.

                  10.2 RIGHTS TO PURCHASE OTHER SECURITIES. If any of the
         following shall occur:

                           (a) any consolidation or merger to which the Company
                  is a party, other than a consolidation or a merger in which
                  the Company is the continuing or surviving

                                       13


<PAGE>   14



                  Company and which does not result in any reclassification of,
                  or change (other than as a result of a subdivision or
                  combination) in, outstanding shares of the Common Stock, or

                           (b) any sale or transfer to another corporation or
                  entity of all or substantially all of the assets of the
                  Company;

         then, and in either such case, the Holder of each Warrant then
         outstanding shall have the right to purchase the kind and amount of
         shares of stock and/or other securities and property receivable upon
         such consolidation, merger, sale or transfer by a holder of the number
         of shares of Common Stock issuable upon exercise of such Warrant
         immediately prior to such consolidation, merger, sale, or transfer. The
         provisions of this Section 10.2 shall similarly apply to successive
         consolidations, mergers, sales or transfers.

                  10.3 NOTICE OF ADJUSTMENT. Whenever the number of shares of
         Warrant Stock purchasable upon the exercise of each Warrant or the
         Warrant Price of such Warrant Stock is adjusted or reduced, as herein
         provided, the Company shall mail by first class, postage prepaid, to
         each Holder (a) notice of any reduction on or before the day the
         reduction takes effect, which shall state the reduced Warrant Price and
         the period during which it will be in effect and/or (b) a certificate
         setting forth the number of shares of Warrant Stock purchasable upon
         the exercise of each Warrant and the Warrant Price on such Warrant
         Stock after adjustment setting forth a brief statement of the facts
         requiring such adjustment and setting forth the computation by which
         such adjustment was made.

                  10.4 NO ADJUSTMENT FOR DIVIDENDS. No adjustment in respect of
         any cash dividends shall be made during the term of a Warrant or upon
         the exercise or conversion of a Warrant.

                  10.5 CERTAIN EVENTS. If any event occurs as to which in the
         reasonable judgment of the Board of Directors of the Company, in good
         faith, the other provisions of this Section 9 are not strictly
         applicable but the lack of any adjustment would not in the opinion of
         the Board of Directors of the Company fairly reflect the purchase
         rights of the Holders of the Warrants in accordance with the basic
         intent and principles of the provisions of this Agreement then the
         Board of Directors of the Company shall appoint a Financial Advisor
         which shall give its opinion upon the adjustment, if any, on a basis
         consistent with the basic intent and principles established and the
         other provisions of this Section 9, necessary to preserve, without
         dilution, the exercise rights of the Holders. Upon receipt of such
         opinion, the Company shall forthwith make the adjustments described
         therein which adjustments shall be conclusive and binding.

         11.      Redemption of Warrants.
                  ----------------------

                           (a) Upon ten (10) days prior notice (a "Redemption

                  shall mean an underwritten public offering of shares of Common

<PAGE>   17



                  shall be deemed terminated. All Warrants not previously issued
                  as of a Redemption Event shall not subsequently be issued by
                  the Company and Purchasers shall have no rights to such

         13.      Certificates to Bear Legends.
                  ----------------------------

                           (a) The Warrant Certificates and certificates
                  representing shares of Warrant Stock shall be subject to a
                  stop-transfer order and each such certificate shall bear the
                  following legends by which each Holder shall be found:

                  THE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
                  ACT OF 1933 ("ACT"). THEY MAY NOT BE SOLD, OFFERED FOR SALE,
                  PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE
                  REGISTRATION STATEMENT AS TO THE SECURITIES UNDER THE ACT OR
                  AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH
                  REGISTRATION IS NOT REQUIRED. THESE SECURITIES HAVE BEEN
                  ISSUED UNDER AND ARE GOVERNED BY AND ARE SUBJECT TO THAT
                  CERTAIN WARRANT AGREEMENT DATED MARCH 6, 1997 (THE WARRANT
                  AGREEMENT). A COPY OF THE WARRANT AGREEMENT CAN BE OBTAINED
                  FROM THE SECRETARY OF THE COMPANY.

                           (b) In addition, so long as the Security holders'
                  Agreement remains in effect all such certificates referred to
                  in paragraph (a) above shall also bear the following legend:

                  THESE SECURITIES ARE SUBJECT TO CERTAIN RESTRICTIONS ON
                  TRANSFER AND OTHER TERMS SET FORTH IN THAT CERTAIN AMENDED AND
                  RESTATED STOCKHOLDERS' AGREEMENT DATED AS OF MARCH __, 1997,
                  AS IT MAY BE AMENDED FROM TIME TO TIME, A COPY OF WHICH
                  AGREEMENT CAN BE OBTAINED FROM THE SECRETARY OF THE COMPANY.

         14. NO RIGHTS AS STOCKHOLDERS; NOTICES TO HOLDERS; UNISSUED WARRANTS.
Nothing contained in this Agreement or in any of the Warrant Certificates shall
be construed conferring upon the Holders or their transferees the right to vote
or to receive dividends or to consent to or receive

                                       17


<PAGE>   18



notice as stockholders in respect of any meeting of stockholders for the
election of directors of the Company or on any other matter, or any rights
whatsoever as stockholders of the Company. Warrants as to which the conditions
precedent to issuance are not satisfied shall be void and of no effect, and no
Purchaser or other party shall have any rights with respect thereto.

         15. INVESTMENT INTENT. The Warrants to be purchased pursuant to this
Agreement are being purchased for each Purchaser's own account and with no
intention of distributing or reselling the Warrants. The Holder understands that
neither the Warrants nor the Common Stock have been registered under the Act or
any applicable state securities laws and that neither the Warrants nor the
Common Stock can be sold, transferred or otherwise disposed of without
registration under the Act and applicable state securities laws, unless it has
been established to the satisfaction of the Company that they may be sold,
transferred or otherwise disposed of without such registration.

         16. NOTICES. Any notice pursuant to this Agreement to be given or made
by the Holder of any Warrant Certificate to or on the Company shall be
sufficiently given or made if delivered personally or sent by telecopier or by
certified mail, addressed to the Chief Financial Officer of the Company at the
Company's principal executive offices at 4100 Holiday Street, N.W., Suite 201,
Canton, Ohio 44718 (unless notice has been given of a change of such address),
and shall be effective three (3) days after having been mailed or upon receipt
if delivered personally or sent by telecopier, with receipt confirmed by the
office of the President. Notices or demands authorized by this Agreement to be
given or made to the Holder of any Warrant Certificate shall be sufficiently
given or made if delivered personally or sent by certified mail or by
telecopier, addressed to such Holder at the address of such Holder as shown on
the Warrant Register, and shall be effective three (3) days after having been
mailed or upon receipt if delivered personally or sent by telecopier, with
receipt confirmed.

         17. GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of Ohio.

         18. SUPPLEMENTS, AMENDMENTS AND WAIVERS. Any supplement or amendment
to, or any waiver of any provision of, this Agreement shall be effective when
consented to in writing by the Holders of a majority of the Warrants then
outstanding (determined as though there were one Warrant for each share of
Common Stock issuable on the exercise of the then outstanding Warrants) and by
the Company.

         19. SUCCESSORS. All the covenants and provisions of this Agreement by
or for the benefit of the Company or the Holders shall bind and inure to the
benefit of their respective successors and assigns hereunder.

         20. COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which so executed shall be deemed to be an original; but
such counterparts together shall constitute but one and the same instrument.

         1.       Exercise Provisions.
                  -------------------

                  (a) MANNER OF EXERCISE. This Warrant may be exercised by the
         holder of this Warrant surrendering to the Company at its principal
         office at 4100 Holiday Street, N.W., Suite 201, Canton, Ohio 44718, or
         such other address as to which the Company may hereafter give notice to
         the holder, this Warrant, together with the exercise form attached to
         this Warrant duly executed by the holder together with payment to the
         Company in the amount obtained by multiplying the Purchase Price by the
         number of shares of Common Stock designated in the exercise form.
         Payment may be in cash or by cashier's or certified bank check payable
         to the order of the Company, or by conversion of the unpaid principal

         and accrued interest under the Notes in the manner set forth in the 
         Notes and the Warrant Agreement.

                  (b) PARTIAL EXERCISE. On any partial exercise, the Company
         shall promptly issue and deliver to the holder of this Warrant a new
         Warrant or Warrants of like tenor in the name of that holder providing
         for the right to purchase that number of shares of Common Stock as to
         which this Warrant has not been exercised.

         2. DELIVERY OF STOCK CERTIFICATES. Within a reasonable time after full
or partial exercise of this Warrant, the Company at its expense will cause to be
issued in the name of and delivered to the holder of this Warrant in accordance

         3. COMPLIANCE WITH SECURITIES ACT; DISPOSITION OF WARRANT OR SHARES OF
COMMON STOCK. The holder of this Warrant, by acceptance hereof, agrees that this
Warrant and the Shares of Common Stock to be issued upon exercise hereof are
being acquired for investment and that the holder will not offer, sell or
otherwise dispose of this Warrant or any Shares of Common Stock to be issued
upon exercise hereof, except under circumstances which will not result in a
violation of the Securities Act of 1933, as amended (the "Act") nor violate the
terms of the Warrant Agreement and, if then applicable, the Amended and Restated
Stockholders' Agreement (as defined in the Warrant Agreement). In addition, any
permitted Warrant transferee will be required to agree to the provisions of this
Section 3. The provisions of this Section 3 shall not apply to any shares of
Common Stock, the issuance or resale of which is registered under the Act.

         4.       Miscellaneous Provisions.
                  ------------------------

                  (a) RESERVATION OF STOCK. The Company covenants that it will
         at all times reserve and keep available, solely for issuance upon
         exercise of this Warrant, all shares of Common Stock or other
         securities from time to time issuable upon exercise of this Warrant.

                  (b) MODIFICATION. This Warrant and any of its terms may be
         changed, waived, or terminated only by a written instrument signed by
         the party against whom enforcement of that change, waiver or
         termination is sought.

                  (c) REPLACEMENT. On receipt of evidence reasonably
         satisfactory to the Company of the loss, theft, destruction, or
         mutilation of this Warrant and subject to the requirements of the
         Warrant Agreement, the Company will execute and deliver, in lieu of
         this Warrant, a new Warrant of like tenor.

                  (d) WARRANT AGENT. The Company may, on written notice to the
         holder of this Warrant, appoint an agent having an office in Cleveland,
         Ohio, for the purposes of issuing Common Stock upon the exercise of
         this Warrant and of replacing or exchanging this

         Warrant, and after that appointment any such issuance, replacement, or
         exchange shall be made at that office by that agent.

                  (e) NO RIGHTS AS STOCKHOLDER. No holder of this Warrant, as
         such, shall, solely by holding this Warrant, be entitled to vote or
         receive dividends or be considered a stockholder of the Company for any
         purpose, nor shall anything in this Warrant be construed to confer on
         any holder of this Warrant as such, any rights of a stockholder of the
         Company or any right to vote, to give or withhold consent to any
         corporate action, to receive notice of meeting of stockholders, to
         receive dividends or subscription rights or otherwise.

         anti-dilution protection as to the Shares of Common Stock to be issued
         upon exercise as specifically set forth in the Warrant Agreement which
         may result in the adjustment from time to time of the Purchase Price
         and/or the number of shares of Common Stock issuable upon the exercise
         hereof.

                  (g) NOTICES. Notices hereunder to the holder of this Warrant
         shall be sent as provided in the Warrant Agreement.

         government, the Fourth Amended and Restated Certificate of
         Incorporation (as amended) or the By-laws of the Company, or any
         provision of any indenture, agreement or other instrument by which the
         Company or any of its properties or assets is bound or affected, or

         Title 13, Code of Federal Regulations, ss. 121.101 ET SEQ.), is a
         "small business concern" within the meaning of the Small Business Act
         and the regulations thereunder, including Title 13, Code of Federal
         Regulations, ss. 121.101 ET SEQ. The information regarding the Company

         Investment Company is prohibited from providing funds by the Small
         Business Act and the regulations thereunder (including Title 13, Code
         of Federal Regulations, ss. 107.720 ET SEQ.).

                        (g) OFFERING OF THE NOTES. Neither the Company nor any

         registration provisions of the Act.

         Agreement nor any Schedule annexed hereto, nor any certificate or other
         instrument referred to herein and furnished to the Purchasers by the
         Company, contains any untrue statement of a material fact or omits to
         state a material fact necessary in order to make the statements
         contained therein or herein, in the light of the circumstances under
         which they were made, not misleading. During the course of the
         transaction and prior to any Purchaser's purchase of the Notes, the
         Company has provided to such Purchaser, or allowed such Purchaser free
         access to, the information sufficient to allow the Purchasers to make

         projected balance sheet as of the end of such fiscal year, and each
         monthly financial statement furnished pursuant to 9(b) above shall
         reflect variances from such operating budget, as same may from time to
         time be revised; provided, however, that in the event that such annual
         budget cannot be prepared within such 30-day period because of
         inadequacies in the accounting system of any entity acquired by the
         Company, the Company shall furnish such annual budget as soon
         thereafter as is possible, and the Company shall use reasonable efforts
         to remedy such inadequacies so that future annual budgets may be
         prepared within the applicable 30-day periods;

         regarding the operations, business, affairs and financial condition of
         the Company or any Subsidiary as Purchaser or any permitted transferee
         of a Purchaser may reasonably request.

         5.2 COMPLIANCE WITH SMALL BUSINESS INVESTMENT ACT. The Company agrees
to provide River Cities and NCCC with sufficient information to permit River

acquisitions, and/or for working capital. If the Company shall, without the
consent of such Purchaser, use the proceeds from such Purchaser's investment for
a purpose not described above, such Purchaser may demand that the Company
repurchase the Note and Warrants at a price equal to the purchase price paid for
such securities as required by SBA Regulations Section 107.305. Further, the
Company will use the investment proceeds from each Purchaser to repay any
overadvance under the Loan Documents with respect to which Brantley is a
guarantor.

not pay cash dividends on its capital stock.

                                  -------------

         6.1 SUBORDINATION. So long as, and from time to time while, any Senior
Indebtedness is outstanding, anything in this Agreement or the Notes to the
contrary notwithstanding, the indebtedness of the Company hereunder as evidenced
by the Notes shall be subordinate and junior in right of payment, to the extent
and in the manner set forth in this Article VI, to all Senior Indebtedness of
the Company from time to time outstanding (whether outstanding at the date of
this Agreement or incurred after the date of this Agreement) and as the Notes
may at any time and from

time to time be modified or amended in any respect and to all other indebtedness
hereafter made or assumed by the Company, which by the terms of such
indebtedness or by the terms of any indenture or other instrument pursuant to
which such indebtedness is made, assumed or incurred is specifically designated
as "Senior Indebtedness" for the purposes of this Agreement and which is
permitted to be issued, made, assumed and incurred according to the terms of
this Agreement provided that such indebtedness is included within the definition
of Senior Indebtedness as set forth in the following paragraph (a).

                  (a) "Senior Indebtedness" means all indebtedness and other
         obligations specified below whether outstanding on the date of this
         Agreement or hereafter created, incurred or assumed by the Company:

                           (i) the obligations of the Company and its

                  all expenses, reimbursements, indemnities and other amounts
                  payable by the Company thereunder;

                  indebtedness of the Company which by its express terms is made
                  senior to the Notes; provided, however, that any indebtedness
                  incurred by the Company under this clause (ii) must be created
                  in connection with or arise out of a transaction in which the
                  Company or any Subsidiaries of the Company received cash loan
                  proceeds, property or credit support in the form of a letter
                  of credit, guaranty or like instrument;

                           (iii) all interest accrued or accruing on Senior
                  Indebtedness after the commencement of any insolvency,
                  bankruptcy or receivership case or proceeding in accordance
                  with and at the contract rate (including, without limitation,
                  any rate applicable upon default) specified in the agreement
                  or instrument creating, evidencing or governing any such
                  Senior Indebtedness, whether or not, pursuant to applicable
                  law or otherwise, the claim for such interest is allowable as
                  a claim in such case or proceeding; and

                           (iv) subject to Section 2.3(c) above, any
                  refinancings, refundings, renewals or extensions, in whole or
                  in part, of any indebtedness or other obligation described in
                  clauses (i) or (ii) above under any Subsequent Loan Documents

                  (b) In the event of (i) any insolvency or bankruptcy
         proceeding brought by or against the Company; (ii) any receivership,
         liquidation, reorganization or other similar proceeding relative to the
         Company or to its property, including its Subsidiaries; or (iii) any
         proceedings for voluntary liquidation, dissolution or other winding up
         of the Company, whether or not involving insolvency or bankruptcy, the
         holders of Senior Indebtedness shall be entitled to receive payment in
         full in cash of all principal, premium (if any), fees and

                                       18


<PAGE>   22



         charges in respect of, and interest on, all Senior Indebtedness
         (including interest thereon accruing after the commencement of any such
         proceedings) before the holders of the Notes shall be entitled to
         receive any payment or distribution in respect of the Notes. Pursuant
         to the foregoing, the holders of Senior Indebtedness (until payment in
         full in cash of all principal, premium (if any), fees and charges in
         respect of, and interest on, all Senior Indebtedness, including
         interest thereon accruing after the commencement of any such
         proceedings at the rate specified in the applicable Senior Indebtedness
         whether or not such interest is an allowable claim in such case or
         proceeding) shall be entitled to receive for application and payment
         thereof any payment or distribution of any kind or character, whether
         in cash or property or securities, which may be payable or deliverable
         in any such proceedings in respect of the Notes (including any such
         payment or distribution which may be payable or deliverable by virtue
         of the provisions of, or any security for, any securities which are
         subordinate and junior in right of payment of the Notes). The Holders
         of the Notes shall not exercise or attempt to exercise any right of set
         off or counterclaim in respect of any obligations of the Holders of the
         Notes to the Company against the obligations of the Company under the
         Notes if the effect thereof shall be to reduce the amount of any such
         payment or distribution to which the holders of Senior Indebtedness
         would be entitled in the absence of such set off or counterclaim; and
         if and to the extent that notwithstanding the foregoing, the Holders of
         the Notes are required by any mandatory provision of law to exercise
         any such right of set off or counterclaim each reduction of the amount
         owing on account of the principal of or interest on the Notes by reason
         of such set off or counterclaim shall be deemed to be a payment by the
         Company in a like manner in respect of the Notes to which the second
         sentence of this paragraph (b) shall apply.

                  (c) In the event that any default shall occur and be
         continuing with respect to any Senior Indebtedness permitting the
         holders, with or without the making of demand, the giving of notice or
         otherwise, of such Senior Indebtedness to accelerate the maturity
         thereof, the Company shall not pay and the Holders shall not be
         entitled to receive any payment or distribution in respect of the Notes
         of any kind, whether of principal, premium (if applicable) or interest
         or, except to the extent otherwise provided in Section 6.2 of this
         Agreement, institute any judicial or legal proceedings or seek to
         enforce any other rights or remedies whatsoever UNLESS AND UNTIL (i) a
         period of one hundred seventy-five (175) days (the "Blocking Period")
         shall have elapsed from the date of such default without the same
         having been cured or waived; and (ii) the Blocking Period shall have
         elapsed without any holder of Senior Indebtedness having accelerated
         the maturity of such Senior Indebtedness, but in such event, upon the
         satisfaction of the conditions set forth in (i) and (ii) above, the
         holders of the Notes will have the rights and remedies contemplated by
         this Agreement.

                  (d) Nothing in this Agreement will prohibit the holder of any
         Senior Indebtedness at any time and from time to time without the
         consent of or notice to any holder of the Notes from taking any of the
         following actions:

                                       19


<PAGE>   23



                           (i) subject to Section 2.3(c) above, extending,
                  renewing, modifying, waiving or amending the terms of such
                  Senior Indebtedness;

                           (ii) following 5 days notice to the Noteholders of
                  the terms thereof, (or, in the case of an auction, the time
                  and place of sale) the sale other than by the Company in the
                  ordinary course of business of any material portion of the
                  property pledged, mortgaged or otherwise securing Senior
                  Indebtedness in accordance with the terms of the Loan
                  Documents or the Subsequent Loan Documents, PROVIDED, HOWEVER,
                  that the failure to deliver such notice shall not otherwise
                  prohibit such Person from effecting such sale pursuant to the
                  terms of the Loan Documents or the Subsequent Loan Documents;

                           (iii) exchanging, releasing or otherwise dealing with
                  any property pledged, mortgaged or otherwise securing Senior
                  Indebtedness or releasing a guarantor or any other person
                  liable in any manner for the Senior Indebtedness or amending
                  or waiving the terms of any guaranty of the Senior
                  Indebtedness;

                           (iv) exercising or refraining from exercising any
                  rights against the Company or any other person;

                           (v) applying any sums, in any manner, by whomever
                  paid or however realized, to the Senior Indebtedness; and

                           (vi) taking any other action which otherwise might be
                  deemed to impair the rights of the holders of the Senior
                  Indebtedness.

                  Subject to the terms of this Agreement, any and all of such
         actions may be taken by the holders of Senior Indebtedness without
         incurring responsibility to any Holder of the Notes and without
         impairing or releasing the obligations of any Holder of the Notes to
         the holders of Senior Indebtedness.

                  (e) No right of any present or future holder of any Senior
         Indebtedness to enforce the provisions of this Article VI shall at any
         time in any way be prejudiced or impaired by any action or failure to
         act on the part of the Company or anyone in custody of its assets or
         property or by any act or any failure to act on the part of any such
         holder or any other holder of Senior Indebtedness or by any breach by
         the Company of the terms of this Agreement or the Notes, irrespective
         of any knowledge thereof on the part of any such holder or any other
         holder of Senior Indebtedness.

                  (f) Each Holder of the Notes will at all times retain the
         right to vote its claims and otherwise act and participate in any
         insolvency, bankruptcy or reorganization proceeding relative to the
         Company; provided, however, no Holder of the Notes shall take any
         action or

                                       20


<PAGE>   24



         vote its claims in the course of any such bankruptcy, insolvency or 
         reorganization proceedings so as to:

                           (i) contest the validity or the enforceability of the
                  agreements governing Senior Indebtedness including the Loan
                  Documents or any Subsequent Loan Documents, the promissory
                  notes issued to the holders of Senior Indebtedness, or the
                  liens and security interests to the extent granted with
                  respect to the Senior Indebtedness;

                           (ii) contest the rights and duties of the holders of
                  Senior Indebtedness established in the agreements or
                  instruments governing the same or any security agreement with
                  respect to such liens and security interests;

                           (iii) contest the validity or enforceability of this
                  Article VI;

                           (iv) contest the validity or enforceability of this
                  Agreement or any agreement or instrument to the extent
                  evidencing or relating to the Indebtedness of Company to such
                  Holder; or

                           (v) compromise their claims so as to deprive the
                  holders of Senior Indebtedness of the benefit of receiving all
                  amounts otherwise payable to the Holders of the Notes pursuant
                  to the reorganization or liquidation of the Company resulting
                  from such proceeding;

         it being understood that nothing contained in this Section 6.1(f) shall
         be deemed to relieve the Company of its obligations under Section
         2.3(c) of this Agreement.

                  (g) No Affiliate or Subsidiary of the Company may take any
         action or make any payment in respect of or in regard to the Notes if
         the Company would be prohibited from taking such action or making such
         payment pursuant to this Article VI.

                  (h) The provisions of this Article VI shall be given
         independent effect so that if a particular payment as to the Notes is
         prohibited by any one of such provisions, it shall be prohibited
         although it otherwise may not be prohibited by any other provisions.

         6.2 SUBROGATION Subject to the payment in cash in full of all Senior
Indebtedness, the Holders of the Notes shall be subrogated to the rights of the
holders of Senior Indebtedness to receive payments or distributions of assets of
the Company payable or distributable to the holders of Senior Indebtedness and,
as among the Company and its Subsidiaries, their creditors and the holders of
the Notes, no payments or distributions otherwise payable or deliverable in
respect of the Notes but by virtue of the provisions thereof and of Section 6.1,
paid or delivered to the holders of Senior Indebtedness shall be deemed to be a
payment by the Company on account of the Notes.

                                       21


<PAGE>   25



         6.3 CONSTRUCTIVE TRUST, ETC. In the event that any Noteholder receives
any payment or distribution in contravention of the provisions hereof, such
Holder shall hold such payment or distribution in trust for the benefit of the
holders of Senior Indebtedness, and shall deliver such payment or distribution
to the holders of such Senior Indebtedness, or their respective representatives,
ratably according to the aggregate amounts remaining unpaid on account of the
Senior Indebtedness held or represented by each, to the extent necessary to make
payment in cash in full of all Senior Indebtedness remaining unpaid after giving
effect to any concurrent payment or distribution to the holders of such Senior
Indebtedness.

         6.4 RESTRICTIONS ON ADDITIONAL SUBORDINATED INDEBTEDNESS. The Company
will not create or suffer to exist any Indebtedness that (i) provides that it is
subordinate in right of payment to the Senior Indebtedness other than the Notes
and (ii) is senior in right of payment to the Notes or is secured.

         The Company shall give to each Noteholder a copy of any notice of
acceleration of the maturity date of any Senior Indebtedness promptly upon
receipt thereof.

         No present or future holder of Senior Indebtedness shall be prejudiced
in such holder's right to enforce subordination of any Note by any act or
failure to act on the part of the Company or anyone in custody of its assets or
property. The provisions of this Article VI are solely for the purpose of
defining the relative rights of the holders of Senior Indebtedness on one hand,
and the Holders of the Notes on the other hand, and nothing herein shall impair,
as between the Company and the Holders of the Notes, the obligation of the
Company, which is unconditional and absolute, to pay the Holders thereof the
principal and interest thereon in accordance with the terms thereof.

                                   ARTICLE VII
                                   -----------
                                    DEFAULTS
                                    --------

         7.1 DEFAULTS. If any of the following events (herein called an "Event
of Default" or collectively "Events of Default") shall have occurred and be
continuing, that is to say:

                  (a) default shall be made in the payment of any interest,
         principal or premium (if any) when due on any of the Notes and such
         default shall have continued for a period of twelve (12) days; or

                  (b) the Company breaches or defaults in the performance of any
         provision of this Agreement and such breach or default shall have
         continued for a period of thirty (30) days; or

                  (c) the Company defaults in any payment of principal of or
         interest on any Senior Indebtedness, beyond any period of grace
         provided with respect thereto or in the performance of any other term
         or condition contained in any agreement under which any such obligation
         is created if the effect of such default results in Senior Indebtedness
         in excess of $1,000,000

                                       22


<PAGE>   26



         becoming due prior to its stated maturity without such indebtedness
         being discharged or such acceleration being rescinded or annulled
         within a period of sixty (60) days; or

                  (d) an order for relief shall be entered in any federal
         bankruptcy proceeding in which the Company is the debtor; or
         bankruptcy, receivership, insolvency, reorganization, relief,
         dissolution, liquidation or other similar proceedings shall be
         instituted by or against the Company or all or any part of the property
         of the Company under the Federal Bankruptcy Code or any other
         bankruptcy or insolvency law of the United States or any bankruptcy or
         insolvency law of any state of competent jurisdiction unless, if such
         proceedings are instituted against the Company, such proceedings are
         dismissed and discharged within ninety (90) days after they are
         instituted; or

                  (e) the Company shall have become insolvent or unable to pay
         its debts as they mature, cease doing business as a going concern,
         undergo dissolution or liquidation, make an assignment for the benefit
         of creditors, admit in writing its inability to pay its debts as they
         become due, or if a trustee, receiver or liquidator shall be appointed
         for the Company, or for any substantial portion of the assets of the
         Company, and such appointment shall not be vacated within ninety (90)
         days; or

                  (f) further, any diversion by the Company of the proceeds
         hereunder from the use of proceeds as delineated in Section 5.3 shall
         be an Event of Default pertaining to River Cities and NCCC requiring
         the immediate repayment of River Cities' and NCCC's Notes and full
         refund of the purchase price for their Warrants, plus accrued and
         unpaid interest on the Notes.

then, except as provided below with respect to an Event of Default under
paragraph (a) of this Section 7.1, the Holder of the Note if only one Note shall
be outstanding, or the Holders of at least a majority of the principal amount of
the Notes, if more than one Note shall be outstanding, may at its or their
option, after notice in writing to the Company, declare the Note or all of the
Notes, as the case may be, to be forthwith due and payable and thereupon the
Note, or all of the Notes, shall be and become due and payable, together with
interest and all other amounts accrued thereon (provided that if an Event of
Default results from the filing of a voluntary petition in any bankruptcy
proceeding or the filing of an involuntary petition in any bankruptcy proceeding
which is not dismissed and discharged within ninety (90) days, the Notes
thereupon shall immediately become due and payable, with interest accrued
thereon, without any notice from the holders of the Notes or otherwise), and,
subject to the provisions of Article VI hereof, the Holder or Holders of the
Note or Notes may take any action or proceeding at law or in equity which it or
they deem advisable for the protection of its or their interests to collect and
enforce payment and the Company shall pay all expenses, court costs and
reasonable attorneys' fees incurred in connection with or arising out of any
default hereunder. Notwithstanding the foregoing, in case an Event of Default
under paragraph (a) of this Section 7.1 shall occur, the Holders shall have none
of the rights and remedies otherwise contemplated by this Section 7.1
(including, without limitation, the right to accelerate the maturity of the
Notes) UNLESS AND UNTIL (i) Blocking Period shall have elapsed from the date of

         amount of Notes, the consent of whose Holders is required for any
         waiver or amendments provided for in this Agreement. No amendment or
         modification of any provision of this Agreement in accordance with the
         terms hereof shall be effective unless such amendment or modification
         is (i) in writing and (ii) consented to by Holders of not less than
         two-thirds (2/3) or more of the principal amount of the Notes then
         outstanding.

                                                                      Exhibit 3

                                 WATERLINK, INC.
                   AMENDED AND RESTATED 1995 STOCK OPTION PLAN

          1. GENERAL. This Stock Option Plan (the "Plan") provides eligible
employees of Waterlink, Inc., a Delaware corporation (the "Company"), and its
subsidiaries with the opportunity to acquire or expand their equity interest in
the Company by making available for award or purchase shares of Common Stock,
 .001 par value, of the Company ("Common Stock"), through the granting of
nontransferable options to purchase shares of Common Stock ("Stock Options").
Stock Options shall be referred to herein as "Grants," and an individual grant
of Stock Options shall be referred to herein as a "Grant."

          It is intended that key employees may be granted simultaneously or
from time to time, Stock Options that qualify as incentive stock options
("Incentive Stock Options") under Section 422 of the Internal Revenue Code of
1986, as amended (the "Code"), or Stock Options that do not so qualify
("Non-qualified Stock Options"). No provision of the Plan is intended or shall
be construed to grant employees alternative rights in any Incentive Stock Option
granted under the Plan so as to prevent such Option from qualifying under
Section 422 of the Code.

          The Plan is intended to conform to the extent necessary with all
provisions of the Securities Act of 1933, as amended (the "Securities Act"), and
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and any
and all regulations and rules promulgated by the Securities and Exchange
Commission thereunder, including, without limitation, Rule 16b-3.
Notwithstanding anything herein to the contrary, the Plan shall be administered,
and Stock Options shall be granted and may be exercised, only in such a manner
as to conform to such laws, rules and regulations. To the extent permitted by
applicable law, the Plan and Stock Options granted hereunder shall be deemed
amended to the extent necessary to conform to such laws, rules and regulations.

          2. PURPOSE OF THE PLAN. The purpose of the Plan is to provide
continuing incentives to key employees of the Company and of any subsidiary
corporation of the Company, by encouraging such key employees to acquire new or
additional share ownership in the Company, thereby increasing their proprietary
interest in the Company's business and enhancing their personal interest in the
Company's success.

          For purposes of the Plan, a "subsidiary corporation" consists of any
corporation fifty percent (50%) of the stock of which is directly or indirectly
owned or controlled by the Company.

          3. EFFECTIVE DATE OF THE PLAN. The Plan shall become effective upon
its adoption by the Board of Directors of the Company (the "Board"), subject to
approval by holders of a majority of the outstanding shares of voting capital
stock of the Company. If the Plan is not so approved within twelve (12) months
after the date the Plan is adopted by the Board, the Plan and any Grants made
hereunder shall be null and void, However, if the Plan is so approved, no
further shareholder approval shall be required with respect to the making of
Grants pursuant to the Plan, except as provided in Section 12 hereof.

          4. ADMINISTRATION OF THE PLAN. The Plan shall be administered by the
Board unless and until the Board appoints a committee composed of no fewer than,
two (2) members of the Board (the

                                        1


<PAGE>   2



"Committee"). No person shall be appointed to the Committee who, during the one
(1) year period immediately preceding such person's appointment to the
Committee, has received any Grants under the Plan or any similar stock option or
stock incentive plan, other than formula-based plan, maintained by the Company
or any subsidiary corporation. A member of the Committee shall not be eligible
to participate in the Plan while serving on the Committee.

          A majority of the members of the Committee shall constitute a quorum.
The acts of a majority of the members present at any meeting at which a quorum
is present (or acts unanimously approved in writing by the members of the
Committee, shall constitute binding acts of the Committee.

          Subject to the terms and conditions of the Plan, Board, or the
Committee, if any (hereinafter the "Administrator") shall be authorized and
empowered:

               (a) To select the key employees to whom Grants may be made;

               (b) To determine the number of shares of Common Stock to be
          covered by any Grant;

               (c) To prescribe the terms and conditions of any Grants made
          under the Plan, and the form(s) and agreement(s) used in connection
          with such Grants, which shall include agreements governing the
          granting of Stock Options which may provide that the stock which is
          the subject of any such Grant shall be subject to the restrictions on
          transfer contained in any agreement in effect among the Company and
          one or more of its stockholders;

               (d) To determine the time or times when Stock Options will be
          granted and when they will terminate in whole or in part;

               (e) To determine the time or times when Stock Options that are
          granted may be exercised; provided, however, that unless the
          Administrator specifically determines otherwise in any individual
          instance, the standard vesting schedule for Stock Options granted
          hereunder shall be four equal yearly installments;

               (f) To determine, at the time a Stock Option is granted under the
          Plan, whether such Stock Option is an Incentive Stock Option entitled
          to the benefits of Section 422 of the Code; and

               (g) To establish any other Stock Option agreement provisions not
          inconsistent with the terms and conditions of the Plan or, where the
          Stock Option is an incentive Stock Option, with the terms and
          conditions of Section 422 of the Code.

          5. EMPLOYEES ELIGIBLE FOR GRANTS. Grants may be made from time to time
to those key employees of the Company or a subsidiary corporation who are
designated by the Administrator in its sole and exclusive discretion. Key
employees may include, but shall not necessarily be limited to, members of the
Board of Directors (excluding members of the Committee) and officers of the
Company and any subsidiary corporation; however, Stock Options intended to
qualify as Incentive

                                        2


<PAGE>   3



Stock Options shall be granted to key employees only while actually employed by
the Company or a subsidiary corporation. The Administrator may grant more than
one Stock Option to the same key employee. No Stock Option shall be granted to
any key employee during any period of time when such key employee is on a leave
of absence.

          6. STOCK SUBJECT TO THE PLAN. The shares to be issued pursuant to any
Grant made under the Plan shall be shares of Common Stock. Either shares of
Common Stock held as treasury stock or authorized and unissued shares of Common
Stock, or both, may be so issued, in such amount or amounts within the maximum
limits of the Plan as the Administrator shall from time to time determine.

          Subject to the provisions of the next succeeding paragraph of this
Section 6 and the provisions of Section 7(h), the aggregate number of shares of
Common Stock that can be actually issued under the Plan shall be Eight Hundred
Thousand (800,000).

          If, at any time subsequent to the date of adoption of the Plan by the
Board of Directors, the number of shares of Common Stock increased or decreased,
or changed into or exchanged for a different number or kind of shares of stock
or other securities of the Company or of another corporation (whether as a
result of a stock split, stock dividend, combination or exchange of shares,
exchange for other securities, reclassification, reorganization, redesignation,
merger, consolidation, recapitalization or otherwise): (i) there shall
automatically be substituted for each share of Common Stock subject to an
unexercised Stock Option (in whole or in part) granted under the Plan, the
number and kind of shares of stock or other securities into which each share of
outstanding Common Stock shall be changed or for which each such share of Common
Stock shall be exchanged; and (ii) the option price per share of Common Stock or
unit of securities shall be increased or decreased proportionately so that the
aggregate purchase price for the securities subject to a Stock Option shall
remain the same as immediately prior to such event. In addition to the
foregoing, the Administrator shall be entitled in the event of any such
increase, decrease or exchange of shares of Common Stock to make other
adjustments to the securities subject to a Stock Option, the provisions of the
Plan, and to any related Stock Option agreements (including adjustments which
may provide for the elimination of fractional shares) where necessary (under
Section 422(a)(2) of the Code or otherwise) to preserve the terms and conditions
of any Grants hereunder.

          7.   STOCK OPTION PROVISIONS.

               (a) GENERAL. The Administrator may grant to key employees (also
          referred to as "optionees") nontransferable Stock Options that either
          qualify as Incentive Stock Options under Section 422 of the Code or do
          not so qualify. However, any Stock Option which is an Incentive Stock
          Option shall only be granted within ten (10) years from the earlier of
          (i) the date this Plan is adopted by the Board and (ii) the date this
          Plan is approved by the stockholders of the Company.

               (b) STOCK OPTION PLAN. The option price per share of Common Stock
          which may be purchased under an Incentive Stock Option under the Plan
          shall be determined by the Administrator at the time of Grant, but
          shall not be less than one hundred percent (100%) of

                                        3


<PAGE>   4



          the fair market value of a share of Common Stock, determined as of the
          date such Option is granted; however, if a key employee to whom an
          Incentive Stock Option is granted is, at the time of the grant of such
          Option, an "owner" as defined in Section 422(b)(6) of the Code
          (modified as provided in Section 424(d) of the Code) of more than ten
          percent (10%) of the total combined voting power of all classes of
          stock of the Company or any subsidiary corporation (a "Substantial
          Shareholder"), the price per share of Common Stock of such Option, as
          determined by the Administrator, shall not be less than one hundred
          ten percent (110%) of the fair market value of a share of Common Stock
          on the date such Option is granted. The option price per share of
          Common Stock under each Stock Option granted pursuant to the Plan
          which is not an Incentive Stock Option shall be determined by the
          Administrator at the time of Grant. Except as specifically provided
          above, the fair market value of a share of Common Stock shall be
          determined in accordance with procedures to be established by the
          Administrator. The day on which the Administrator approves the
          granting of a Stock Option shall be considered the date on which such
          Option is granted.

               (c) PERIOD OF STOCK OPTION. The Administrator shall determine
          when each Stock Option is to expire. However, no Incentive Stock
          Option shall be exercisable after the expiration of ten (10) years
          from the date upon which such Option is granted, or five (5) years
          from the date upon which such Option is granted to a Substantial
          Shareholder.

               (d) LIMITATION ON EXERCISE AND TRANSFER OF STORK OPTIONS. Only
          the key employee to whom a Stock Option is granted may exercise such
          Option, except where a guardian or other legal representative has been
          duly appointed for such employee, and except as otherwise provided in
          the case of such employee's death. No Stock Option granted hereunder
          shall be transferable by an optionee other than by will or the laws of
          descent and distribution. No Stock Option granted hereunder may be
          pledged or hypothecated, nor shall any such Option be subject to
          execution, attachment or similar process.

               (e) EMPLOYMENT, HOLDING PERIOD REQUIREMENTS FOR CERTAIN OPTIONS.
          The Administrator may condition any Stock Option granted hereunder
          upon the continued employment of the optionee by the Company or by a
          subsidiary corporation. and may make any such Stock Option immediately
          exercisable. However, the Administrator will require that, from and
          after the date of grant of any Incentive Stock Option granted
          hereunder until the day three (3) months prior to the date such Option
          is exercised, such optionee must be an employee of the Company or of a
          subsidiary corporation, but always subject to the right of the Company
          or any such subsidiary corporation to terminate such optionee's
          employment during such period (except if the optionee's employment is
          terminated due to death or permanent and total disability, in which
          event such period shall be one (1) year). Each Stock Option shall be
          subject to such additional restrictions as to the time and method of
          exercise as shall be prescribed by the Administrator. Upon compliance
          with any condition or requirement imposed by the Administrator
          pursuant to the foregoing, a Stock Option or the appropriate portion
          thereof may be exercised in whole or in part from time to time during
          the option period; however, such exercise right(s) shall be limited to
          whole shares.

                                        4

               (f) PAYMENT FOR STOCK OPTION PRICE. A Stock Option shall be
          exercised by an optionee giving written notice to the Company of his
          intention to exercise the same, accompanied by full payment of the
          purchase price in cash or by check or, with the consent of the
          Administrator, in whole or in part with a surrender of shares of
          Common Stock having a fair market value on the date of exercise equal
          to that portion of the purchase price for which payment in cash or
          check is not made. The Administrator may, in its sole discretion,
          approve other methods of exercise for a Stock Option or payment of the
          option price, provided that no such method shall cause any option
          granted under the Plan as an Incentive Stock Option to not qualify
          under Section 422 of the Code, or cause any share of Common Stock
          issued in connection with the exercise of an option not to be a fully
          paid and non-assessable share of Common Stock.

               (g) CERTAIN REISSUANCES OF STOCK OPTIONS. To the extent stares of
          Common Stock are surrendered by an optionee in connection with the
          exercise of a Stock Option in accordance with Section 7(f), the
          Administrator may in its sole discretion grant new Stock Options to
          such optionee (to the extent shares of Common Stock remain available
          for Grants), subject to the following terms and conditions:

                    (i) The number of shares of Common Stock shall be equal to
               the number of shares of Common Stock being surrendered by the
               optionee;

                    (ii) The option price per share of Common Stock shall be
               equal to the fair market value of shares of Common Stock,
               determined on the date of exercise of the Stock Options whose
               exercise caused such Grant; and

                    (iii) The terms and conditions of such Stock Options shall
               in all other respect replicate such terms and conditions of the
               Stock Options whose exercise caused such Grant, except to the
               extent such terms and conditions are determined not to be wholly
               consistent with the general provisions of this Section 7, or in
               conflict with the remaining provisions of this Plan.

               (h) CANCELLATION AND REPLACEMENT OF STOCK OPTIONS AND RELATED
          RIGHTS. The Administrator may at any time or from time to time permit
          the voluntary surrender by an optionee who is the holder of any
          outstanding Stock Options under the Plan, where such surrender is
          conditioned upon the granting of such optionee of new Stock Options
          for such number of shares as the Administrator shall determine, or may
          require such a voluntary surrender as a condition precedent to the
          grant of new Stock Options. The Administrator shall determine the
          terms and conditions of new Stock Options, including the prices at and
          periods during which they may be exercised, in accordance with the
          provisions of this Plan, all or any of which may differ from the terms
          and conditions of the Stock Options surrendered. Any such new Stock
          Options shall be subject to all the relevant provisions of this Plan.
          The shares of Common Stock subject to any Stock Option so surrendered,
          and/or any shares of Common Stock subject to any Stock Option that has
          lapsed or been forfeited, shall no longer be charged against the
          limitation provided in Section 6 of the Plan and may again become
          shares subject to the Plan. The granting of new Stock Options in
          connection

                                        5


<PAGE>   6



          with the surrender of outstanding Stock Options under this Plan shall
          be considered for the purposes of the Plan as the granting of new
          Stock Options and not an alteration, amendment or modification of the
          Plan or of the Stock Options being surrendered.

               (i) LIMITATION ON EXERCISABLE INCENTIVE STOCK OPTIONS. The
          aggregate fair market value of the shares of Common Stock first
          becoming subject to exercise as Incentive Stock Options by a key
          employee during any given calendar year shall not exceed the sum of
          One Hundred Thousand Dollars ($100,000). Such aggregate fair market
          value shall be determined as of the date such Option is granted,
          taking into account, in the order in which granted, any other
          Incentive Stock Options granted by the Company, or by a parent or
          subsidiary thereof.

               (j) WITHHOLDING OF TAXES. The Administrator may, in its sole
          discretion, require, as a condition to any Grant or to the delivery of
          certificates for shares issued hereunder, that the optionee pay to the
          Company, in cash, any federal, state or local taxes of any kind
          required by law to be withheld with respect to any Grant or any
          delivery of shares of Common Stock upon exercise thereof. The
          Administrator, in its sole discretion, may permit optionees to pay
          such taxes through the withholding of shares of Common Stock otherwise
          deliverable to such optionee in connection with such Grant or the
          delivery to the Company of shares of Common Stock otherwise acquired
          by the optionee. The Fair Market Value of shares of Common Stock
          withheld by the Company or tendered to the Company for the
          satisfaction of tax withholding obligations under this Section 7(j)
          shall be determined on the date such shares of Common Stock are
          withheld or tendered. The Company, to the extent permitted or required
          by law, shall have the right to deduct from any payment of any kind
          (including salary, bonus, severance or insurance proceeds) otherwise
          due to an optionee any federal, state or local taxes of any kind
          required by law to be withheld with respect to any Grant or to the
          delivery of shares of Common Stock under the Plan, or to retain or
          sell without notice a sufficient number of shares of Common Stock to
          be issued to such optionee to cover any such taxes, provided that the
          Company shall not sell any such shares of Common Stock if such sale
          would be considered a sale by such optionce for purposes of Section 16
          of the Exchange Act.

          8. TERMINATION OF EMPLOYMENT. If a key employee ceases to be an
employee of the company and every subsidiary corporation, for a reason other
than death, retirement, "permanent and total disability" (as defined below) or
such key employee's employment is terminated "without cause" (as defined below),
his Grants shall, unless extended by the Administrator on or before his date of
termination of employment, terminate on the effective date of such termination
of employment. Neither the key employee nor any other person shall have any
right after such date to exercise all or any part of his Stock Options which are
not vested or otherwise subject to restriction and they shall thereupon be
forfeited, declared void and without value, or both.

          If termination of employment is due to death or permanent and total
disability or is without cause, then outstanding Stock Options may be exercised
within the one (1) year period ending on the anniversary of such death,
permanent and total disability or termination without cause (except that, with
respect to Incentive Stock Options held by key employees whose employment is
terminated without cause, such Incentive Stock Options must be exercised within
three (3) months of the date of such termination). In the case of death, such
outstanding Stock Options shall be exercised by such

                                        6


<PAGE>   7



key employee's estate, or the person designated by such key employee by will, or
as otherwise designated by the laws of descent and distribution. Notwithstanding
the forgoing, in no event shall any Stock Option be exercisable after the
expiration of the option period, and in the case of exercises made after a key
employee's death, not to any greater extent than such key employee would have
been entitled to exercise such Option at the time of his death.

          Subject to the discretion of the Administrator, in the event a key
employee terminates employment with the Company and all subsidiary corporations
because of normal or early retirement under any pension plan or retirement plan
hereafter adopted by the Company, or permanent and total disability, any
then-outstanding Stock Options held by such key employee shall lapse at the end
of the term of such Stock Option, or thirty (30) days after such retirement,
whichever first occurs.

          For purposes hereof, "permanent and total disability" means a
permanent and total disability as defined in Section 22(e) of the Code. For
purposes hereof, termination "without cause" means termination of the employee's
employment by the Company for reasons other than (i) conviction of the employee
for a felony or for any crime or offense lesser than a felony involving the
property of the Company or a subsidiary corporation or affiliate of the Company;
(ii) conduct by the employee that has caused demonstrable and serious injury to
the Company or a subsidiary, monetary or otherwise; or (iii) substandard
performance, or material misconduct or negligence in the performance, of the
employee's duties in the reasonable judgment of the Board; provided, however,
that for any employee with a written employment agreement with the Company or
any subsidiary corporation, the without cause" definition, if any, contained in
such employment agreement shall be utilized for purposes hereof.

          In the event an employee of the Company or one of its subsidiary
corporations is granted a leave of absence by the Company or such subsidiary
corporation to enter military service or because of sickness, his employment
with the Company or such subsidiary corporation shall not be considered
terminated, and he shall be deemed an employee of the Company or such subsidiary
corporation during such leave of absence or any extension thereof granted by the
Company or such subsidiary corporation.

          9. AMENDMENTS TO PLAN. The Administrator is authorized to interpret
this Plan and from time to time adopt any rules and regulations for carrying out
this Plan that it may deem advisable. Subject to the approval of the Board, the
Administrator may at any time amend, modify, suspend or terminate this Plan. In
no event, however, without the approval of the stockholders, shall any action of
the Administrator or the Board result in:

               (a) Materially amending, modifying or altering the eligibility
          requirements provided in Section 5 hereof;

               (b) Materially increasing, except as provided in Section 6
          hereof, the maximum number of shares of Common Stock that may be made
          subject to Grants; or

               (c) Materially increasing the benefits accruing to participants
          under this Plan;

                                        7


<PAGE>   8



except to conform this Plan and any agreements made hereunto to changes in the
Code or required by governing law.

          10. INVESTMENT REPRESENTATION, APPROVALS AND LISTING. The
Administrator may, if it deems appropriate, condition its grant of any Stock
Option hereunder upon receipt of the following investment representation from
the optionee:

          "I agree that any shares of Common Stock of Waterlink, Inc. which I
          may acquire by virtue of this Stock Option shall be acquired for
          investment purposes only and not with a view to distribution or
          resale, and may not be transferred, sold, assigned, pledged,
          hypothecated or otherwise disposed of by me unless (i) a registration
          statement or post-effective amendment to a registration statement
          under the Securities Act, with respect to said shares of Common Stock
          has become effective so as to permit the sale or other disposition of
          said shares by me; or (ii) there is presented to Waterlink, Inc. an
          opinion of counsel satisfactory to Waterlink, Inc. to the effect that
          the sale or other proposed disposition of said shares of Common Stock
          by me may lawfully be made otherwise than pursuant to an effective
          registration statement or post-effective amendment to a registration
          statement relating to the said shares under the Securities Act of
          1933, as amended."

          The Company shall not be required to issue any certificate or
certificates for shares of Common Stock upon the exercise of any Stock Option
granted under this Plan prior to (i) the obtaining of any approval from any
governmental agency which the Administrator shall, in its sole discretion,
determine to be necessary or advisable; (ii) the admission of such shares to
listing on any national securities exchange on which the shares of Common Stock
may be listed; (iii) the completion of any registration or other qualifications
of the shares of Common Stock under any state or federal law or ruling or
regulations of any governmental body which the Administrator shall, in its sole
discretion, determine to be necessary or advisable or the determination by the
Administrator, in its sole discretion, that any registration or other
qualification of the shares of Common Stock is not necessary or advisable, or
(iv) the obtaining of an investment representation from the optionee in the form
stated above or in such other form as the Administrator, in its sole discretion,
shall determine to be adequate.

          11. GENERAL PROVISIONS. The form and substance of Stock Option
agreements made hereunder, whether granted at the same or different times, need
not be identical. Nothing in this Plan or in any Stock Option agreement shall
confer upon any employee any right to continue in the employ of the Company or
any of its subsidiary corporations or affiliates or to interfere with or limit
the right of the Company or any subsidiary corporation or affiliate to terminate
his employment at any time, with or without cause. Nothing contained in this
Plan or in any Stock Option shall be construed as entitling any optionee to any
rights of a shareholder as a result of the grant of a Stock Option, until such
time as shares of Common Stock are actually issued to such optionee pursuant to
the exercise of such Option. This Plan may be assumed by the successors and
assigns of the Company. The liability of the Company under this Plan and any
sale made hereunder is limited to the obligations set forth herein with respect
to such sale and no term or provision of this Plan shall be construed to impose
any liability on the Company in favor of any employee (or any other party acting
on his behalf

                                        8


<PAGE>   9


or in his stead) with respect to any loss, cost or expense which such employee
or party may incur in connection with or arising out of any transaction in
connection with this Plan. The cash proceeds received by the Company from the
issuance of shares of Common Stock pursuant to this Plan will be used for
general corporate purposes. The expense of administering this Plan shall be
borne by the Company. The captions and section numbers appearing in this Plan
are inserted only as a matter of convenience. They do not define, limit,
construe or describe the scope or intent of the provisions of this Plan.

          12. PROVISIONS APPLICABLE SOLELY TO INSIDERS. The following provisions
shall apply only to persons who are subject to Section 16 of the Exchange Act
with respect to securities of the Company ("Insiders"), and shall apply to
Insiders notwithstanding any provision of the Plan to the contrary:

               (a) No Insider shall be permitted to transfer any security the
          Company acquired by him, except to the extent permitted by 17 C.F.R.
          Section 240.16a-2(D)(1), upon the exercise of any Stock Option, 
          until at lest [sic] six (6) months and one (1) day after the later 
          of (i) the day on which such security is granted to the Insider or 
          (ii) the day on which the exercise or conversion price of such 
          security is fixed.

               (b) An Insider may elect to have shares withheld from a Grant or
          tender shares to the Company in order to satisfy the tax withholding
          consequences of a Grant only during the period beginning on the third
          business day following the date on which the Company releases the
          financial information specified in 17 C.F.R. Section 
          240.16b-3(e)(1)(ii) and ending on the twelfth business day following 
          such date. Notwithstanding the foregoing, an Insider may elect to 
          have shares withheld from a Grant in order to satisfy tax 
          withholding consequences thereof by providing the Company with a 
          written election to so withhold at least six (6) months in advance 
          of the withholding of shares otherwise issuable upon exercise of a 
          Stock Option.

          13. TERMINATION OF THIS PLAN. This Plan shall terminate on February 1,
2005, and thereafter no Stock Options shall be granted hereunder. All Stock
Options outstanding at the time of termination of this Plan shall continue in
full force and effect according to their terms and the terms and conditions of
this Plan.
