     Section 2.2  Exchange of Certificates.
                  ------------------------

     (a) Prior to the Effective Time, MergerCo shall designate the Company's
registrar and transfer agent, or The Chase Manhattan Bank (or any successor
thereto), or such other bank or trust company as may be approved in writing by
the Company (which approval shall not be unreasonably withheld), to act as
exchange agent for the holders of Shares in connection with the Merger, pursuant
to an agreement providing for the matters set forth in this Section 2.2 and such
other matters as may be appropriate and the terms of which shall be reasonably
satisfactory to the Company (the "Exchange Agent"), to receive the certificates
(the "New Certificates") representing the shares of the Recapitalized Common
Stock and the funds to which holders of Shares shall become entitled pursuant to
Section 2.1 (a). At the Effective Time, the Surviving Corporation will deposit
in trust with the Exchange Agent, for the benefit of holders of Company Common
Stock, (i) the funds necessary to complete the payments contemplated by Sections
        -
2.1 (a) and 2.2(c) on a timely basis and (ii) the New Certificates.
                                          --

     (b) At the Effective Time, the Surviving Corporation will instruct the
Exchange Agent to promptly, and in any event not later than three business days
following the Effective Time, mail (and to make available

                                       4
<PAGE>
 
for collection by hand) to each holder of record of a certificate or
certificates, which immediately prior to the Effective Time represented
outstanding shares of Company Common Stock (the "Certificates"), whose Shares
were converted pursuant to Section 2.1 (a) into the right to receive the Merger
Consideration (i) a letter of transmittal (which shall specify that delivery
               -
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon delivery of the Certificates to the Exchange Agent and shall be in
such form and have such other provisions as MergerCo and the Company may
reasonably specify) and (ii) instructions for use in effecting the surrender of
                         --
the Certificates in exchange for the Merger Consideration (which shall provide
that at the election of the surrendering holder, Certificates may be
surrendered, and payment therefor collected, by hand delivery). Upon surrender
of a Certificate for cancellation to the Exchange Agent or to such other agent
or agents as may be appointed by the Company, together with such letter of
transmittal, duly executed, the holder of such Certificate shall be entitled to
receive in exchange therefor the Merger Consideration for each share of Company
Common Stock formerly represented by such Certificate, to be mailed (or made
available for collection by hand if so elected by the surrendering holder)
within three business days of receipt thereof, and the Certificate so
surrendered shall forthwith be cancelled. If payment of the Merger Consideration
is to be made to a person other than the person in whose name the surrendered
Certificate is registered, it shall be a condition of payment that the
Certificate so surrendered shall be properly endorsed or shall be otherwise in
proper form for transfer and that the person requesting such payment shall have
paid any transfer and other taxes required by reason of the payment of the
Merger Consideration to a person other than the registered holder of the
Certificate surrendered or shall have established to the satisfaction of the
Surviving Corporation that such tax either has been paid or is not applicable.
Until surrendered as contemplated by this Section 2.2, each Certificate (other
than Certificates representing Dissenting Shares) shall be deemed at any time
after the Effective Time to represent only the right to receive the Merger
Consideration as contemplated by this Section 2.2.

     (c) Notwithstanding the foregoing, no fractions of a share of Recapitalized
Common Stock shall be issued in the Merger, but in lieu thereof each holder of
Shares otherwise entitled to a fraction of a share of Recapitalized Common Stock
shall, upon surrender of his or her certificate

                                       5
<PAGE>
 
or certificates, be entitled to receive an amount of cash (without interest)
determined by multiplying the fractional share interest to which such holder
would otherwise be entitled by an amount equal to $2.50.

     (d) In the event any Certificate shall have been lost, stolen or destroyed,
upon the making of an affidavit of that fact by the Person claiming such
Certificate to be lost, stolen or destroyed, the Exchange Agent will issue in
exchange for such lost, stolen or destroyed Certificate the Merger Consideration
deliverable in respect thereof as determined in accordance with this Article II,
provided that the Person (as defined in Section 3.1) to whom the Merger
- --------
Consideration is paid shall, as a condition precedent to the payment thereof,
give the Surviving Corporation a bond in such sum as it may direct or otherwise
indemnify the Surviving Corporation in a manner satisfactory to it against any
claim that may be made against the Surviving Corporation with respect to the
Certificate claimed to have been lost, stolen or destroyed.

     (e) After the Effective Time, the stock transfer books of the Company shall
be closed and there shall be no transfers on the stock transfer books of the
Surviving Corporation of Shares which were outstanding immediately prior to the
Effective Time. If, after the Effective Time, Certificates are presented to the
Surviving Corporation, they shall be cancelled and exchanged for the Merger 
Consideration as provided in this Article II.

     (f) Any portion of the funds deposited with the Exchange Agent (and the
proceeds of any interest and other income received by the Exchange Agent in
respect of all such funds) and any New Certificates that remain unclaimed by the
former stockholders of the Company six months after the Effective Time shall be
delivered to the Surviving Corporation. Any former shareholders of the Company
who have not theretofore complied with this Article II shall thereafter look
only to the Surviving Corporation for payment of any Merger Consideration that
may be payable upon surrender of any Certificates such shareholder holds, as
determined pursuant to this Agreement, without any interest thereon.

     (g) None of MergerCo, the Company, the Surviving Corporation, the Exchange
Agent or any other person shall be liable to any former holder of shares of
Company Common Stock for any amount properly delivered to a public official

                                       6
<PAGE>
 
pursuant to applicable abandoned property, escheat or similar laws.

     (h) Any payment made pursuant to this Section 2.2 shall be subject to and
made net of applicable withholding taxes.

     Section 2.3 Options. The Board shall take all actions necessary or
                 -------
appropriate to cause all options to purchase Company Common Stock (individually,
a "Company Stock Option" and collectively, the "Company Stock Options") granted
to any current or former employee or director of the Company or any Subsidiary
under any of the Company's 1982 Incentive Stock Option Plan, 1992 Stock Option
Plan or 1994 Stock Option or Incentive Plan prior to the date hereof
(collectively, the "Company Stock Plans") and that are outstanding immediately
prior to the Effective Time to be fully vested and exercisable immediately prior
to the Effective Time in accordance with the terms of the Company Stock Plans
and the individual agreements evidencing such Company Stock Options. Each
Company Stock Option that is not exercised prior to the Effective Time shall,
subject to the consent of the holder thereof, be cancelled at the Effective Time
and, in consideration thereof, each holder of such a Company Stock Option will
be entitled to receive, for each share of Company Common Stock subject to such
Company Stock Option, an amount in cash equal to the excess, if any, of the sum
(such sum, the "Aggregate Merger Consideration Value") of (i) $47.75 and the
                                                           -
cash value of 0.5 shares of Recapitalized Common Stock, such cash value to be
$1.25, representing one half of the per share price paid by the Fund for a share
of common stock of MergerCo, over (ii) the per share exercise price for such
                                   --
share of Company Common Stock, without interest. Amounts contributed on or prior
to March 31, 1998 for the purchase of Company Common Stock pursuant to the terms
of the Employee Stock Purchase Plan that have not theretofore been applied to
the purchase of such Company Common Stock in accordance with the terms of such
plan shall be applied to the purchase of such Company Common Stock immediately
prior to the Effective Time based on a purchase price per share equal to 85% of
the lesser of (x) the closing price per share of Company Common Stock on the New
York Stock Exchange ("NYSE") on October 1, 1997 and (y) the Aggregate Merger
Consideration Value, and the Employee Stock Purchase Plan shall be amended as
required by the proviso contained in Section 5.1(d)(ii) and shall be terminated
immediately following the consummation of the purchase of Company Common Stock
contemplated hereby. Each share of Company Common Stock issued in accordance
with the

                                       7
<PAGE>
 
     immediately preceding sentence shall be treated in the same manner as each
other share of Company Common Stock outstanding at the Effective Time. The
Company shall use its reasonable best efforts to obtain prior to the Effective
Time any consent of current or former employees and/or directors required to
effect the cancellation of options contemplated hereby. Notwithstanding the
foregoing, the Company Stock Options of the individuals listed on Schedule 2.3
(as such Schedule 2.3 may be amended from time to time after the date hereof and
prior to the Effective Time by MergerCo to include additional employees, with
the consent of each such additional employee) shall, in connection with the
Merger, be treated as set forth on Schedule 2.3. The amounts payable pursuant to
this Section 2.3 shall be paid as soon as reasonably practicable following the
Closing Date and shall be subject to and made net of all applicable withholding
taxes.

     Section 2.4 Dissenting Shares. Notwithstanding anything in this Agreement
                 -----------------
to the contrary, Shares which are issued and outstanding immediately prior to
the Effective Time and which are held by shareholders who have validly demanded
payment of the fair value for such shareholders' shares as determined by
appraisal in accordance with the MBCL (the "Dissenting Shares"), shall not be
converted into or be exchangeable for the right to receive the Merger
Consideration provided in Section 2.1(a) of this Agreement, unless and until
such holder shall have failed to perfect or shall have effectively withdrawn or
lost such holder's right to appraisal and payment under the MBCL. If such holder
shall have so failed to perfect or shall have effectively withdrawn or lost such
right, such holder's Shares shall thereupon be deemed to have been converted
into and to have become exchangeable for, at the Effective Time, the right to
receive the consideration provided for in Section 2.1 of this Agreement, without
any interest thereon.

                                                               --
in any discussions or negotiations regarding any Company Takeover Proposal;
provided, however, that if and to the extent that, at any time prior to the time
- --------  -------
of the adoption of this Agreement by the Company's shareholders at the Special
Meeting, the Board of Directors of the Company determines in good faith, after
consultation with outside counsel, that it is necessary to do so in order to act
in a manner consistent with its fiduciary duties to the Company's shareholders
under applicable law, the Company may, in response to any Company Takeover
Proposal which was not solicited by it and which did not otherwise result from a
breach of this Section 5.2(a), and subject to providing prior notice of any such
proposal or any such request for non-public information and of its decision to
take such action to MergerCo and compliance with Section 5.2(c), (x) furnish
information with respect to the Company and its Subsidiaries to any person
inquiring about or making a Company Takeover Proposal pursuant to a customary

of the Company and its Subsidiaries, taken as a whole, or 50% or more of any
class of equity securities of the Company, any tender offer or exchange offer
that if consummated would result in any person beneficially owning 50% or more
of any class of any

                                       35
<PAGE>

involving the Company (or any Subsidiary whose business constitutes 50% or more
of the net revenues, net income or assets of the Company and its Subsidiaries
taken as a whole), other than the transactions contemplated by this Agreement.

     (b) Except as expressly permitted by this Section 5.2, neither the Board of
Directors of the Company, the Special Committee nor any other committee shall
(i) withdraw or modify or propose publicly to withdraw or modify, in a manner
 -
adverse to MergerCo, the approval or recommendation by such Board of Directors
or such committee of the Merger or this Agreement, (ii) approve or recommend, or
                                                    --

Agreement") related to any Company Takeover Proposal unless prior to the
adoption of this Agreement by the Company's shareholders at the Special Meeting,
the Board of Directors of the Company, to the extent that it determines in good
faith, following the recommendation of the Special Committee and after
consultation with outside counsel, that in light of a Company Superior Proposal

fiduciary duties. For purposes of this Agreement, a "Company Superior Proposal"
means any proposal made by a third party to acquire, directly or indirectly,
including pursuant to a tender offer, exchange offer, merger, consolidation,

then outstanding or all or substantially all the assets of the Company and
otherwise on terms which the Board of Directors of the Company determines in its

Merger.

     (c) In addition to the obligations of the Company set forth in paragraphs
(a) and (b) of this Section 5.2, the Company shall immediately advise MergerCo
orally and in writing of any request for information or of any Company Takeover
Proposal and the material terms and conditions of such request or Company
Takeover Proposal.

     (d) Nothing contained in this Section 5.2 shall prohibit the Company from
taking and disclosing to its shareholders a position contemplated by Rule

of the Company, after consultation with outside counsel, failure so to disclose
would be inconsistent with its obligations under applicable law; provided,
                                                                 --------

position with respect to this Agreement or the Merger or approve or recommend,
or propose publicly to approve or recommend, a Company Takeover Proposal except
to the extent permitted by Section 5.2(b).

it during such period pursuant to the requirements of the Exchange Act or other
applicable Law and (b) such other information concerning its business,
                    -
properties and personnel as MergerCo may reasonably request. MergerCo and its
authorized representatives will use all reasonable efforts to conduct all such
inspections in a manner which will minimize any material disruptions of the
business and operations of the Company and its Subsidiaries. Until the Effective
Time, MergerCo will hold any such information in accordance with the provisions
of the certain letter agreement, dated November 5, 1997, between CD&R and the
Company (the "Confidentiality Agreement"), and will cause such information to be
so held by its Representatives (as defined in the Confidentiality Agreement) of
MergerCo. Upon a termination of this Agreement pursuant to Section 7.1, MergerCo
and its Representatives shall return or destroy (and hold confidential) all
information provided pursuant to this Section 5.3 and all other Evaluation

authorized by their respective Boards of Directors (and, in the case of the
Company, the Special Committee), at any time before or after approval by the
shareholders of the Company of the matters presented in connection with the
Merger, but after any such approval no amendment shall be made without the
approval of such shareholders if such amendment changes the Merger Consideration
or alters or changes any of the other terms or conditions of this Agreement if
such alteration or change would materially adversely affect the rights of such
shareholders. Except as otherwise provided in Section 2.3 with respect to
Schedule 2.3, this Agreement may not be amended except by an instrument in
writing signed on behalf of each of the parties hereto.

     (b) At any time prior to the Effective Time, the parties may (i) extend the
                                                                   -

                                         ---
agreements or conditions of the other parties hereto contained herein. Any such
extension or waiver by the Company shall require the consent of the Special
Committee or the Board of Directors of the Company. Any agreement on the part of
any party to any such extension or waiver shall be valid only if

                                       51
<PAGE>
 
set forth in an instrument in writing signed on behalf of such party. Any such
waiver shall constitute a waiver only with respect to the specific matter
described in such writing and shall in no way impair the rights of the party
granting such waiver in any other respect or at any other time. Neither the
waiver by any of the parties hereto of a breach of or a default under any of the
provisions of this Agreement, nor the failure by any of the parties, on one or
more occasions, to enforce any of the provisions of this Agreement or to
exercise any right or privilege hereunder, shall be construed as a waiver of any
other breach or default of a similar nature, or as a waiver of any of such
provisions, rights or privileges hereunder. The rights and remedies herein
provided are cumulative and none is exclusive of any other, or of any rights or
remedies that any party may otherwise have at law or in equity. The rights and
remedies of any party based upon, arising out of or otherwise in respect of any
inaccuracy or breach of any representation, warranty, covenant or agreement or
failure to fulfill any condition shall in no way be limited by the fact that the
act, omission, occurrence or other state of facts upon which any claim of any
such inaccuracy or breach is based may also be the subject matter of any other
representation, warranty, covenant or agreement as to which there is no
inaccuracy or breach. The representations and warranties of the Company shall
not be affected or deemed waived by reason of any investigation made by or on
behalf of MergerCo (including but not limited to any of its advisors, counsel,
consultants or representatives) or by reason of the fact that MergerCo or any of
such advisors, counsel, consultants or representatives knew or should have known
that any such representation or warranty is or might be inaccurate.

                 --------

documents delivered prior to or as of the Effective Time shall not survive

the right to make written requests that the Company effect registrations under
the Securities Act of all or part of the Registrable Securities of the holder or
holders making such request, which requests shall specify the intended method of
disposition thereof by such holder or holders.

               (b)   OBLIGATION TO EFFECT REGISTRATION. Upon receipt by the
                     ---------------------------------
Company of any request for registration pursuant to Section 3.1(a), the Company
will promptly give written notice of such requested registration to all holders
of Registrable Securities, and thereupon will use its best efforts to effect the
registration under the Securities Act of

                (i)  the Registrable Securities which the Company has been so
        requested to register pursuant to Section 3.1(a), and

               (ii)  all other Registrable Securities which the Company has been
        requested to register by the holders thereof by written request given to
        the Company within 30 days after the Company has given such written
        notice (which request shall specify the intended method of disposition
        of such Registrable Securities),

all to the extent required to permit the disposition (in accordance with the
intended methods thereof as aforesaid) of the Registrable Securities so to be
registered. Notwithstanding the preceding sentence:

               (x) the Company shall not be required to effect a registration
        requested pursuant to Section 3.1(A) if (a) with respect to the first
                                          -
        three such requests, the aggregate number of Registrable Securities
        referred to in clauses (i) and (ii) of the preceding sentence to be
        included in such registration shall be less than 22,300,000 shares and
        (B) thereafter, the number of Registrable Securities to be so included
         -
        shall be less than 11,150,000, PROVIDED, that in no event shall the
                                       --------
        Company be required to effect a registration requested pursuant to
        Section 3.1(a) if the Board determines, in its good faith judgment,
        after consultation with a firm of nationally recognized underwriters
        that the aggregate net proceeds from the disposition of the Registrable
        Securities for which registration has been so requested would be less
        than $15,000,000.00; and

                                       5
<PAGE>
 
               (y) if the Board determines in its good faith judgment, after
        consultation with a firm of nationally recognized underwriters, that
        there will be an adverse effect on a then contemplated Public Offering,
        the Requisite Percentage of Stockholders shall be given notice of such
        fact and shall be deemed to have withdrawn such request and such
        registration shall not be deemed to have been effected or requested
        pursuant to this Section 3.1.

               (c) REGISTRATION STATEMENT FORM. Each registration requested
                   ---------------------------
pursuant to this Section 3.1 shall be effected by the filing of a registration
statement on Form S-1, Form S-2 or Form S-3 (or any other form which includes
substantially the same information as would be required to be included in a
registration statement on such forms as presently constituted), the choice of
such form to be made by holders holding at least a majority (by number of
shares) of the Registrable Securities as to which registration has been
requested pursuant to this Section 3.1, unless the use of a specific or
different form is required by law.

               (d) EXPENSES. The Company will pay all Registration Expenses in
                   --------
connection with the first five registrations effected pursuant to a request
under Sec tion 3.1(a). The Registration Expenses in connection with each other
registration, if any, requested under Section 3.1(a) shall be apportioned among
the holders whose Registrable Securities are then being registered, on the basis
of the respective amounts (by number of shares) of Registrable Securities then
being registered. However, in the case of each registration requested under
Section 3.1(a), the Company shall pay all amounts in respect of (a) any
allocation of salaries of personnel of the Company and its Subsidiaries or other
general overhead expenses of the Company and its Subsidiaries or other expenses
for the preparation of financial statements or other data normally prepared by
the Company and its Subsidiaries in the ordinary course of its business, (B)
                                                                          -
the expenses of any officers' and directors' liability insurance, (C) the
                                                                   -
expenses and fees for listing the securities to be registered on each exchange
on which similar securities issued by the Company are then listed or, if no such
securities are then listed, on an exchange selected by the Company or on NASDAQ
and (D) all fees associated with filings required to be made with the NASD
     -
(including, if required, the fees and expenses of any "qualified independent
underwriter" and its counsel). Notwithstanding the provisions of this Section
3.1(d) or of Section 3.2, each seller of Registrable Securities shall pay all
Registration Expenses to the extent required to be paid by such seller by
applicable law.

               (e) INCLUSION OF OTHER SECURITIES. The Company shall not register
                   -----------------------------
securities (other than Registrable Securities) for sale for the account of any
Person other than the Company in any registration requested pursuant to Section
3.1(a) unless permitted to do so by the written consent of holders holding at
least a majority (by num-

                                       6
<PAGE>
 
ber of shares) of the Registrable Securities proposed to be sold in such
registration which consent shall not unreasonably be withheld, it being
understood and agreed that such holders shall not be deemed to be unreasonable
if they in their good faith judgment believe that the inclusion of the
securities of any such other Person will adversely affect the price or
marketability of the shares such holders of Registrable Securities or the
Company propose to sell in such registration.

               (f) EFFECTIVE REGISTRATION STATEMENT. A registration requested
                   --------------------------------
pursuant to Section 3.1(a) will not be deemed to have been effected unless it
has become effective for the period specified in Section 3.3(b). Notwithstanding
the preceding sentence, a registration requested pursuant to Section 3.1(a)
which does not become effective after the Company has filed a registration
statement with respect thereto solely by reason of the refusal to proceed of the
holder or holders of Registrable Securities requesting the registration shall be
deemed to have been effected by the Company at the request of such holder or
holders.

               (g) PRO RATA ALLOCATION. If the holders of a majority (by number
                   -------------------
of shares) of the Registrable Securities for which registration is being
requested pursuant to Section 3.1(a) determine, based on consultation with the
managing underwriters or, in an offering which is not underwritten, with an
investment banker, that the number of securities to be sold in any such
offering should be limited due to market conditions or otherwise, holders of
Registrable Securities proposing to sell their securities in such registration
shall share pro rata in the number of securities being offered (as determined by
the holders holding a majority (by number of shares) of the Registrable
Securities for which registration is being requested in consultation with the
managing underwriters or investment banker, as the case may be) and registered
for their account, such sharing to be based on the number of Registrable
Securities as to which registration was requested by such holders and the number
of securities that the Company proposed to sell for its own account in such
offering, respectively.

               3.2. INCIDENTAL REGISTRATION. If the Company at any time proposes
                    -----------------------
to register any of its equity securities (as defined in the Exchange Act) under
the Securities Act (other than pursuant to Section 3.1 or pursuant to a Special
Registration), whether or not for sale for its own account, and the registration
form to be used may be used for the registration of Registrable Securities, it
will at such time give prompt written notice to all holders of Registrable
Securities of its intention to do so and, upon the written request of any holder
of Registrable Securities given to the Company within 30 days after the Company
has given any such notice (which request shall specify the Registrable
Securities intended to be disposed of by such holder and the intended method of
disposition thereof), the Company will use its best efforts to effect the
registration under

                                       7
<PAGE>
 
the Securities Act of all Registrable Securities which the Company has been so
requested to register by the holders thereof, to the extent required to permit
the disposition (in accordance with the intended methods thereof as aforesaid)
of the Registrable Securities so to be registered, PROVIDED that:
                                                   --------

               (a) if such registration shall be in connection with the first
        public offering of Common Stock following the Merger, the Company shall
        not include any Registrable Securities in such proposed registration if
        the Board shall have determined, after consultation with the managing
        underwriters for such offering, that it is not in the best interests of
        the Company to include any Registrable Securities in such registration,
        PROVIDED that, if the Board makes such a determination, the Company
        --------
        shall not include in such registration any securities not being sold for
        the account of the Company;

               (b) if, at any time after giving written notice of its intention
        to register any securities and prior to the effective date of the
        registration statement filed in connection with such registration, the
        Board shall determine for any reason not to register such securities,
        the Company may, at its election, give written notice of such
        determination to each holder of Registrable Securities that was
        previously notified of such registration and, thereupon, shall not
        register any Registrable Securities in connection with such registration
        (but shall nevertheless pay the Registration Expenses in connection
        therewith), without prejudice, however, to the rights of any holder or
        holders of Registrable Securities to request that a registration be
        effected under Section 3.1; and

               (c) if the Company shall be advised in writing by the managing
        underwriters (or, in connection with an offering which is not
        underwritten, by an investment banker) that in their or its opinion the
        number of securities requested to be included in such registration
        (whether by the Company, pursuant to this Section 3.2 or pursuant to any
        other rights granted by the Company to a holder or holders of its
        securities to request or demand such registration or inclusion of any
        such securities in any such registration) exceeds the number of such
        securities which can be sold in such offering,

                       (i) the Company shall include in such registration the
               number (if any) of Registrable Securities so requested to be
               included which in the opinion of such underwriters or investment
               banker, as the case may be, can be sold and shall not include in
               such registration any securities (other than securities being
               sold by the Company, which shall have priority in being included
               in such registration) so requested to be included other than

                                       8
<PAGE>
 
               Registrable Securities unless all Registrable Securities
               requested to be so included are included therein, and

                      (ii) if in the opinion of such underwriters or investment
               banker, as the case may be, some but not all of the Registrable
               Securities may be so included, all holders of Registrable
               Securities requested to be included therein shall share pro rata
               in the number of shares of Registrable Securities included in
               such public offering on the basis of the number of Registrable
               Securities requested to be included therein by such holders,
               PROVIDED that, in the case of a registration initially requested
               --------
               or demanded by a holder or holders of securities other than
               Registrable Securities, pursuant to a contractual registration
               obligation, the holders of the Registrable Securities requested
               to be included therein and the holders of such other securities
               shall share pro rata (based on the number of shares if the
               requested or demanded registration is to cover only Common Stock
               and, if not, based on the proposed offering price of the total
               number of securities included in such public offering requested
               to be included therein),

        and the Company shall so provide in any registration agreement
        hereinafter entered into with respect to any of its securities.

               The Company will pay all Registration Expenses in connection with
each registration of Registrable Securities requested pursuant to this Section
3.2. No registration effected under this Section 3.2 shall relieve the Company
from its obligation to effect registrations upon request under Section 3.1.

               3.3. REGISTRATION PROCEDURES. If and whenever the Company is
                    -----------------------
required to use its best efforts to effect the registration of any Registrable
Securities under the Securities Act as provided in Sections 3.1 and 3.2, the
Company will promptly:

               (a)  subject to clauses (x), (y) and (z) of Section 3.1(b),
        prepare and file with the Securities and Exchange Commission within 120
        days, after receipt of a request pursuant to Section 3.1 a registration
        statement with respect to such securities, make all required filings
        with the NASD and use best efforts to cause such registration statement
        to become effective;

               (b)  prepare and file with the Securities and Exchange Commission
        such amendments and supplements to such registration statement and the
        prospectus used in connection therewith and such other documents as may
        be necessary to

<PAGE>
 
        keep such registration statement effective and to comply with the
        provisions of the Securities Act with respect to the disposition of all
        securities covered by such registration statement until such time as all
        of such securities have been disposed of in accordance with the intended
        methods of disposition by the seller or sellers thereof set forth in
        such registration statement, but in no event for a period of more than
        six months after such registration statement becomes effective;

               (c) furnish to counsel (if any) selected by the holders of a
        majority (by number of shares) of the Registrable Securities covered by
        such registration statement and to counsel for the underwriters in any
        underwritten offering copies of all documents proposed to be filed with
        the Securities and Exchange Commission (including all documents to be
        filed on a confidential basis) in connection with such registration,
        which documents will be subject to the review of such counsel;

               (d) furnish to each seller of such securities, without charge,
        such number of conformed copies of such registration statement and of
        each such amendment and supplement thereto (in each case, including all
        exhibits and documents filed therewith (other than those filed on a
        confidential basis), except that the Company shall not be obligated to
        furnish any seller of securities with more than two copies of such
        exhibits and documents), such number of copies of the prospectus
        included in such registration statement (including each preliminary
        prospectus and any summary prospectus) in conformity with the
        requirements of the Securities Act, and such other documents, as such
        seller may reasonably request in order to facilitate the disposition of
        the securities owned by such seller;

               (e) use its best efforts to register or qualify the securities
        covered by such registration statement under such other securities or
        blue sky laws of such jurisdictions as each seller shall request, and do
        any and all other acts and things which may be necessary or advisable to
        enable such seller to consummate the disposition in such jurisdictions
        of the securities owned by such seller, except that the Company shall
        not for any such purpose be required to qualify generally to do business
        as a foreign corporation in any jurisdiction wherein it is not so
        qualified, subject itself to taxation in any jurisdiction wherein it is
        not so subject, or take any action which would subject it to general
        service of process in any jurisdiction wherein it is not so subject;

               (f) furnish to each seller a signed counterpart, addressed to the
sellers, of

               accountants who have issued an audit report on the Company's
               financial statements included in the registration statement,
               subject to such seller having executed and delivered to the
               independent public accountants such certificates and documents as
               such accountants shall reasonably request,

        covering substantially the same matters with respect to the registration
        statement (and the prospectus included therein) and, in the case of such
        accountants' letter, with respect to events subsequent to the date of
        such financial statements, as are customarily covered in opinions of
        issuer's counsel and in accountants' letters delivered to the
        underwriters in underwritten public offerings of securities;

               (g) (i) notify each seller of any securities covered by such
                    -
        registration statement if such registration statement, at the time it or
        any amendment thereto became effective, contained an untrue statement of
        a material fact or omitted to state a material fact required to be
        stated therein or necessary to make the statements therein not
        misleading, and, as promptly as practicable, prepare and file with the
        Securities and Exchange Commission a post-effective amendment to such

        so amended, shall not contain an untrue statement of a material fact or
        omit to state a material fact required to be stated therein or necessary
        to make the statements therein not misleading, and (ii) notify each

        holder of Registrable Securities covered by such registration
        statement, at any time when a prospectus relating thereto is required to
        be delivered under the Securities Act, if the prospectus included in
        such registration statement, as then in effect, includes an untrue
        statement of a material fact or omits to state a material fact required
        to be stated therein or necessary to make the statements therein, in
        light of the circumstances under which they were made, not misleading,
        and, as promptly as is practicable, prepare and furnish to such holder a
        reasonable number of copies of a supplement to or an amendment of such
        prospectus as may be necessary so that, as thereafter delivered to the
        purchasers of such securities, such prospectus shall not include an
        untrue statement of a material fact or omit to state a material fact
        required to be stated therein or necessary to make the statements
        therein, in light of the circumstances under which they were made, not

        practicable, an earnings statement of the Company complying with the
        provisions of Section 11 (a) of the Securities Act and Rule 158 under
        the Securities Act;

        used in connection therewith shall have been filed, (ii) of any request
        by the Securities and Exchange Commission to amend such registration
        statement or to amend or supplement such prospectus or for additional
        information, (iii) of the issuance by the Securities and Exchange

        Commission of any stop order suspending the effectiveness of such
        registration statement or of any order preventing or suspending the use

        qualification of such securities for offering or sale in any
        jurisdiction, or of the institution of any proceedings for any of such
        purposes;

                                             -
        securities exchange on which the Common Stock is then listed or, if no
        Common Stock is then listed, on an exchange selected by the Company, if
        such listing is then permitted under the rules of such exchange or (B)

        if such listing is not practicable or the Board determines that
        quotation as a NASDAQ National Market System security is preferable, to
        secure designation of such securities as a NASDAQ "national market
        system security" within the meaning of Rule 11Aa2-1 under the Exchange
        Act or, failing that, to secure NASDAQ authorization for such
        securities, and, without limiting the foregoing, to arrange for at least
        two market makers to register as such with respect to such securities

        Registrable Securities; and

        order that might be issued suspending the effectiveness of such
        registration statement or of any order preventing or suspending the use
        of any preliminary prospectus.

               The Company may require each seller of any securities as to which
any registration is being effected to furnish to the Company such information
regarding such seller and the distribution of such securities as the Company may
from time to time

                                       12

reasonably request in writing and as shall be required by law in connection
therewith. Each such holder agrees to furnish promptly to the Company all
information required to be disclosed in order to make the information previously
furnished to the Company by such holder not materially misleading.

               The Company agrees not to file or make any amendment to any
registration statement with respect to any Registrable Securities, or any
amendment of or supplement to the prospectus used in connection therewith, which
refers to any seller of any securities covered thereby by name, or otherwise
identifies such seller as the holder of any securities of the Company, without
the consent of such seller, such consent not to be unreasonably withheld, except
that no such consent shall be required for any disclosure that is required by
law.

               By acquisition of Registrable Securities, each holder of such
Registrable Securities shall be deemed to have agreed that upon receipt of any
notice from the Com pany pursuant to Section 3.3(g), such holder will promptly
discontinue such holder's disposition of Registrable Securities pursuant to the
registration statement covering such Registrable Securities until such holder
shall have received, in the case of clause (i) of Section 3.3(g), notice from
the Company that such registration statement has been amended, as contemplated
by Section 3.3(g), and, in the case of clause (ii) of Section 3.3(g), copies of
the supplemented or amended prospectus contemplated by Sec tion 3.3(g). If so
directed by the Company, each holder of Registrable Securities will deliver to
the Company (at the Company's expense) all copies, other than permanent file
copies, in such holder's possession of the prospectus covering such Registrable
Securities at the time of receipt of such notice. In the event that the Company
shall give any such notice, the period mentioned in Section 3.3(b) shall be
extended by the number of days during the period from and including the date of
the giving of such notice to and in cluding the date when each seller of any
Registrable Securities covered by such registration statement shall have
received the copies of the supplemented or amended prospectus contemplated by
Section 3.3(g).

               Notwithstanding any other provision of this Agreement, the
parties hereto acknowledge that the Company shall have no obligation to prepare
or file any registration statement prior to the time that financial information
required to be included therein is available for inclusion therein.

               3.4. UNDERWRITTEN OFFERINGS. The provisions of this Section 3.4
                    ----------------------
do not establish additional registration rights but instead set forth procedures
applicable, in addi tion to those set forth in Sections 3.1 through 3.3, to any
registration which is an underwritten offering.

                                       13
<PAGE>
 
               (a) UNDERWRITTEN OFFERINGS EXCLUSIVE. Whenever a registration
                   --------------------------------
requested pursuant to Section 3.1 is for an underwritten offering, only
securities which are to be distributed by the underwriters may be included in
the registration.

               (b) UNDERWRITING AGREEMENT. If requested by the underwriters for
                   ----------------------
any underwritten offering by holders of Registrable Securities pursuant to a
registration re quested under Section 3.1, the Company shall enter into an
underwriting agreement with such underwriters for such offering, such agreement
to be reasonably satisfactory in sub stance and form to the holders of a
majority (by number of shares) of the Registrable Securities to be covered by
such registration and to the underwriters and to contain such representations
and warranties by the Company and such other terms and provisions as are
customarily contained in agreements of this type, including, but not limited to,
indemnities to the effect and to the extent provided in Section 3.7, provisions
for the delivery of officers' certificates, opinions of counsel and accountants'
"comfort" letters and hold-back arrangements. The holders of Registrable
Securities to be distributed by such underwriters shall be parties to such
underwriting agreement and may, at their option, require that any or all of the
representations and warranties by, and the agreements on the part of, the
Company to and for the benefit of such underwriters be made to and for the
benefit of such holders of Registrable Securities and that any or all of the
conditions precedent to the obligations of such underwriters under such
underwriting agreement shall also be conditions precedent to the obligations of
such holders of Registrable Securities. No such holder of Registrable Securities
shall be required by the Company to make any representations or warranties to,
or agreements with, the Company or the underwriters other than as set forth in
Section 3.4(e) and representations, warranties or agreements regarding such
holder and such holder's intended method of distribution.

               (c) SELECTION OF UNDERWRITERS. Whenever a registration requested
                   -------------------------
pursuant to Section 3.1 is for an underwritten offering, the holders of a
majority of the shares requested to be included in such registration will have
the right to select one or more underwriters to administer the offering at least
one of which shall be an underwriter of nationally recognized standing
reasonably satisfactory to the Company. If the Company at any time proposes to
register any of its securities under the Securities Act for sale for its own
account and such securities are to be distributed by or through one or more
underwriters, the Company will have the right to select one or more underwriters
to administer the offering at least one of which shall be an underwriter of
nationally recognized standing.

               (d) INCIDENTAL UNDERWRITTEN OFFERINGS. Subject to the provisions
                   ---------------------------------
of the proviso to the first sentence of Section 3.2, if the Company at any time
proposes to regis-

                                       14
<PAGE>
 
ter any of its equity securities under the Securities Act (other than pursuant
to Section 3.1 or pursuant to a Special Registration), whether or not for its
own account, and such securities are to be distributed by or through one or more
underwriters, the Company will give prompt written notice to all holders of
Registrable Securities of its intention to do so and, if requested by any holder
of Registrable Securities, will arrange for such underwriters to include the
Registrable Securities to be offered and sold by such holder among those to be
distributed by such underwriters. The holders of Registrable Securities to be
distributed by such underwriters shall be parties to the underwriting agreement
between the Company and such underwriters and may, at their option, require that
any or all of the representations and warranties by, and the other agreements on
the part of, the Company to and for the benefit of such underwriters shall also
be made to and for the benefit of such holders of Registrable Securities and
that any or all of the conditions precedent to the obligations of the
underwriters under such underwriting agreement shall also be conditions
precedent to the obligations of such holders of Regis trable Securities. No such
holder of Registrable Securities shall be required by the Company to make any
representations or warranties to, or agreements with, the Company or the
underwriters other than as set forth in Section 3.4(e) and representations,
warranties or agreements regarding such holder and such holder's intended method
of distribution.

               (e) HOLD BACK AGREEMENTS. If and whenever the Company proposes to
                   --------------------
register any of its equity securities under the Securities Act, whether or not
for its own account (other than pursuant to a Special Registration), or is
required to use its best efforts to effect the registration of any Registrable
Securities under the Securities Act pursuant to Section 3.1 or 3.2, each holder
of Registrable Securities, if required by the managing underwriter, agrees by
acquisition of such Registrable Securities not to effect (other than pursuant to
such registration) any public sale or distribution, including, but not limited
to, any sale pursuant to Rule 144 or Rule 144A, of any Registrable Securities,
any other equity securities of the Company or any securities convertible into or
exchangeable or exercisable for any equity securities of the Company during the
20 day period prior to or the 90 day period following the effective date of such
registration, provided that each holder of Registrable Securities further agrees
that, if required by the managing underwriter for such registered offering, he
shall not effect any such public sale or distribution during the 180 day period
following the effective date of such registration, and the Company agrees to
cause each holder of any equity security, or of any security convertible into or
exchangeable or exercisable for any equity security, of the Company purchased or
acquired from the Company at any time other than in a Public Offering to enter
into a similar agreement with the Company. The Company will continue to file
timely and accurately all reports required by Sections 13(a) and 15(d) of the
Exchange Act, until the earlier to occur of (x) the fifth anniversary of the
date hereof

                                       15
<PAGE>
 
and (y) such time as the Common Stock is no longer registered under Section 12
of the Exchange Act.

               3.5. PREPARATION; REASONABLE INVESTIGATION. In connection with
                    -------------------------------------
the preparation and filing of each registration statement registering
Registrable Securities under the Securities Act, the Company will give the
holders of such Registrable Securities so to be registered and their
underwriters, if any, and their respective counsel and accountants the
opportunity to participate in the preparation of such registration statement,
each prospectus included therein or filed with the Securities and Exchange
Commission, and each amendment thereof or supplement thereto, and will give each
of them such access to its books and records and such opportunities to discuss
the business of the Company with its officers and the independent public
accountants who have issued audit reports on its financial statements as shall
be necessary, in the opinion of such holders' and such underwriters' respective
counsel, to conduct a reasonable investigation within the meaning of the
Securities Act.

               3.6. OTHER REGISTRATIONS. If and whenever the Company is required
                    -------------------
to use its best efforts to effect the registration of any Registrable Securities
under the Securities Act pursuant to Section 3.1 or 3.2, and if such
registration shall not have been withdrawn or abandoned, the Company shall not
be obligated to and shall not file any registration statement with respect to
any of its securities (including Registrable Securities) under the Securities
Act (other than a Special Registration), whether of its own accord or at the
request or demand of any holder or holders of such securities, until a period of
six months shall have elapsed from the effective date of such previous
registration.

               3.7.  INDEMNIFICATION.
                     ---------------

               (a)   INDEMNIFICATION BY THE COMPANY. In the event of any
                     ------------------------------
registration of any Registrable Securities under the Securities Act pursuant to
Section 3.1 or 3.2, the Company will indemnify and hold harmless the seller of
such securities, its directors, officers, and employees, each other person who
participates as an underwriter, broker or dealer in the offering or sale of such
securities and each other person, if any, who con trols such seller or any such
participating person within the meaning of either Section 15 of the Securities
Act or Section 20 of the Exchange Act, against any and all losses, claims,
damages or liabilities, joint or several, to which such seller or any such
director, officer, employee, participating person or controlling person may
become subject under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof)
arise out of or are based upon (i) any untrue statement or alleged untrue
                                -
statement of a fact contained in any registration statement under which such
securities were registered under the Securities Act, any preliminary

                                       16
<PAGE>
 
prospectus, final prospectus or summary prospectus contained therein or related
thereto, or any amendment or supplement thereto, or (ii) any omission or alleged
omission to state a fact required to be stated in any such registration
statement, preliminary prospectus, final prospectus, summary prospectus,
amendment or supplement or necessary to make the statements therein not
misleading; and the Company will reimburse such seller and each such director,
officer, employee, participating person and controlling person for any legal or
any other expenses reasonably incurred by them in connection with investigating
or defending any such loss, claim, liability, action or proceeding, PROVIDED
that the Company shall not be liable in any such case to the extent that any
such loss, claim, damage, liability or expense arises out of or is based upon an
untrue statement or omission made in such registration statement, any such
preliminary prospectus, final prospectus, summary prospectus, amendment or
supplement in reliance upon and in conformity with written information furnished
to the Company by such seller or participating person expressly for use in the
preparation thereof and PROVIDED, FURTHER, that the Company shall not be liable
                        --------  -------
in any such case to the extent that any such loss, claim, damage, liability or
expense arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission in the prospectus, if such untrue
statement or alleged untrue statement or omission or alleged omission is
completely corrected in an amendment or supplement to the prospectus and the
seller of Registrable Securities thereafter fails to deliver such prospectus as
so amended or supplemented prior to or concurrently with the sale of Registrable
Securities to the person asserting such loss, claim, damage, liability or
expense after the Company had furnished such seller with a sufficient number of
copies of the same or if the seller received notice from the Company of the
existence of such untrue statement or alleged untrue statement or omission or
alleged omission and the seller continued to dispose of Registrable Securities
prior to the time of the receipt of either (a) an amended or supplemented
prospectus which completely corrected such untrue statement or omission or (b) a
notice from the Company that the use of the existing prospectus may be resumed.
Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of such seller or any such director, officer,
employee, participating person or controlling person and shall survive the
transfer of such securities by such seller.

               (b) INDEMNIFICATION BY THE SELLERS. In the event of any
                   ------------------------------
registration of any Registrable Securities under the Securities Act pursuant to
Section 3.1 or 3.2, each of the prospective sellers of such securities, will
indemnify and hold harmless the Company, each director of the Company, each
officer of the Company who shall sign such registration statement, each other
person who participates as an underwriter, broker or dealer in the offering or
sale of such securities and each other person, if any, who controls the Company
or any such participating person within the meaning of Section 15

                                       17
<PAGE>
 
of the Securities Act or Section 20 of the Exchange Act, against any and all
losses, claims, damages or liabilities, joint or several, to which the Company
or any such director, officer, employee, participating person or controlling
person may become subject under the Securities Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions or proceedings in respect
thereof) arise out of or are based upon (i) any untrue statement or alleged
                                         -
untrue statement of a fact contained in any registration statement under which
such securities were registered under the Securities Act, any preliminary
prospectus, final prospectus or summary prospectus contained therein or related
thereto, or any amendment or supplement thereto, if such statement or omission
was made in reliance upon and in conformity with written information furnished
to the Company by such seller expressly for use in the preparation of such
registration statement, preliminary prospectus, final prospectus, summary
prospectus, amendment or supplement or (ii) any omission or alleged omission to
                                        --
state a fact with respect to such seller required to be stated in any such
registration statement, preliminary prospectus, final prospectus, summary
prospectus, amendment or supplement or necessary to make the statements therein
not misleading; and the seller will reimburse the Company and each such
director, officer, employee, participating person and controlling person for any
legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, liability, action or
proceeding, PROVIDED that the liability of each such seller will be in
            --------
proportion to and limited to the net amount received by such seller (after
deducting any underwriting discount and expenses) from the sale of Registrable
Securities pursuant to such registration statement. Such indemnity shall remain
in full force and effect regardless of any investigation made by or on behalf of
the Company or any such director, officer, participating person or controlling
person and shall survive the transfer of such securities by such seller.

               (c) NOTICES OF CLAIMS, ETC. Promptly after receipt by an
                   ----------------------
indemnified party of notice of the commencement of any action or proceeding
involving a claim referred to in the preceding paragraphs of this Section 3.7,
such indemnified party will, if a claim in respect thereof is to be made against
an indemnifying party hereunder, give written notice to the latter of the
commencement of such action, PROVIDED that the failure of any indemnified party
                             --------
to give notice as provided therein shall not relieve the indemnifying party of
its obligations under the preceding paragraphs of this Section 3.7. In case any
such action is brought against an indemnified party, the indemnifying party will
be entitled to participate therein and to assume the defense thereof, jointly
with any other indemnifying party similarly notified to the extent that it may
wish, with counsel reasonably satisfactory to such indemnified party, and after
notice from the indemnifying party to such indemnified party of its election so
to assume the defense thereof, the indemnifying party will not be liable to such
indemnified party for any legal or other expenses subsequently incurred by the
latter in connection with the defense thereof,

                                       18
<PAGE>
 
PROVIDED that if such indemnified party and the indemnifying party reasonably
- --------
determine, based upon advice of their respective independent counsel, that a
conflict of interest may exist between the indemnified party and the
indemnifying party with respect to such action and that it is advisable for such
indemnified party to be represented by separate counsel, such indemnified party
may retain other counsel, reasonably satisfactory to the indemnifying party, to
represent such indemnified party, and the indemnifying party shall pay all
reasonable fees and expenses of such counsel. No indemnifying party, in the
defense of any such claim or litigation, shall, except with the consent of such
indemnified party, which consent shall not be unreasonably withheld, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect to such claim or
litigation.

               (d) OTHER INDEMNIFICATION. Indemnification similar to that
                   ---------------------
specified in the preceding paragraphs of this Section 3.7 (with appropriate
modifications) shall be given by the Company and each seller of Registrable
Securities with respect to any required registration or other qualification of
such Registrable Securities under any Federal or state law or regulation of
governmental authority other than the Securities Act.

               (e) OTHER REMEDIES. If for any reason the foregoing indemnity is
                   --------------
unavailable, or is insufficient to hold harmless an indemnified party, other
than by reason of the exceptions provided therein, then the indemnifying party
shall contribute to the amount paid or payable by the indemnified party as a
result of such losses, claims, damages, liabilities or expenses (i) in such
                                                                 -
proportion as is appropriate to reflect the relative benefits received by the
indemnifying party on the one hand and the indemnified party on the other from
the offering of Registrable Securities (taking into account the portion of the
proceeds of the offering realized by each such party) or (ii) if the alloca tion
                                                          --
provided by clause (i) above is not permitted by applicable law, or provides a
lesser sum to the indemnified party than the amount hereinafter calculated, in
such proportion as is appropriate to reflect not only the relative benefits
received by the indemnifying party on the one hand and the indemnified party on
the other but also the relative fault of the indemnifying party and the
indemnified party as well as any other relevant equitable considerations. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. No party shall be
liable for contribution under this Section 3.7(e) except to the extent and under
such circumstances as such party would have been liable to indemnify under this
Section 3.7 if such indemnification were enforceable under applicable law.

herein required to be performed by it, only if the Company shall have obtained
the written consent to such amendment, action or omission to act, of the holder
or holders of at least 66% of the shares then constituting Registrable
Securities PROVIDED that this Agreement may not be amended in a manner adversely
           --------
affecting any holder of Registrable Securities which does not adversely affect
all holders of Registrable Securities without the consent of such holder. Each
holder of any Registrable Securities at the time or thereafter outstanding shall
be bound by any consent authorized by this Section 5.1, whether or not such
Registrable Securities shall have been marked to indicate such consent. No
amendment , modification or discharge of this Agreement, and no waiver
hereunder, shall be valid or binding unless set forth in writing. Any such
waiver shall constitute a waiver only with respect to the specific matter
described in such writing and shall in no way impair the rights of the party or
parties granting such waiver in any other respect or at any other time.

               4.2. NOMINEES FOR BENEFICIAL OWNERS. In the event that any
                    ------------------------------
Registrable Securities are held by a nominee for the beneficial owner thereof,
the beneficial owner thereof may, at its election and unless notice is otherwise
given to the Company by the record owner, be treated as the holder of such
Registrable Securities for purposes of any request or other action by any holder
or holders of Registrable Securities pursuant to this Agreement or any
determination of any number or percentage of shares of Registrable Securities
held by any holder or holders of Registrable Securities contemplated by this
Agreement. If the beneficial owner of any Registrable Securities so elects, the
Company may require assurances reasonably satisfactory to it of such owner's
beneficial ownership of such Registrable Securities.

binding upon and shall inure to the benefit of the parties hereto and their
respective successors and assigns. In addition, and whether or not any express
assignment shall have been made, the provisions of this Agreement which are for

benefit of and enforceable by any subsequent holder of any Registrable
Securities, subject to the provisions respecting the

the Qualifying Number, the sale or transfer of a number of shares (the "Excess
                                                                        ------

bination, recapitalization or similar transaction.

          (c)  The obligation of the Fund and the rights of the Employee

by any sale, transfer or dis  tribution referred to, in the preceding sentence

damaged in the event of a breach or a threatened breach by the Fund of any of
its obligations under this Section 3 and the Fund agrees that, in the event of a
breach or a threatened breach by the Fund of any such obligation, the Employee
shall, in addition to any other rights and remedies available to him or her in
respect of such breach, be entitled to an injunction from a court of competent
jurisdiction (without any requirement to post bond) granting it specific
performance by the Fund of its obligations under this Section 3.  In the event
that the Employee shall file suit to

respect of any breach thereof) and prevails in such suit the Employee shall be
entitled to recover from the Company the costs incurred by the Employee in
conducting the suit, including reasonable attorney's fees and expenses.

          (c)  Effect of Take-Along On Options.
               ------------------------------- 

          (i)  Accelerated Vesting and Payment.  Subject to Section 4(c)(ii), in
               -------------------------------

     Employee immediately prior to the closing of such Take-Along Sale shall be
     canceled in exchange for a payment, in cash, of an amount (such amount, the
     "Cancellation Payment Amount") equal to the product of (i) the excess, if
                                                             -

     Take-Along Sale over the exercise price under such Option, multiplied by
     (ii) the 

                                       11
<PAGE>
 
     number of Exercise Shares covered by such Option immediately prior to such
     the consummation of such Take-Along Sale. Payment of the Cancellation
     Payment Amount shall be made as soon as reasonably practicable, but in no
     event later than 30 days, following the closing of the Take-Along Sale.

          (ii)  Alternative Options.  Notwithstanding Section 4(c)(i), no

     settlement or other payment shall be made with respect to any Option in the
     event that the transaction constituting the Take-Along Sale is to be
     accounted for using the "pooling of interest" method of accounting.  In
     such event, each Option held by the Employee immediately prior to the
     closing of the Take-Along Sale shall become fully vested immediately prior
     to the consummation of such transaction and the Employee shall have the
     right, subject to compliance with all applicable securities laws, to (i)

     opportunity is made available by the Take-Along Buyer, exchange such
     Options for fully vested options to purchase common stock of the Take-Along
     Buyer (or the direct or indirect parent of the Take-Along Buyer) having
     substantially equivalent economic value to the Options being exchanged
     therefor, as determined by the Board immediately prior to the consummation
     of the Take-Along Sale.  Any Options not exercised or exchanged shall
     expire upon the consummation of the Take-Along Sale.

          (d)  Remedies.  The Employee acknowledges that the Fund would be
               --------                                                   
irreparably damaged in the event of a breach or a threatened breach by the
Employee of any of his obligations under this Section 4 and the Employee agrees
that, in the event of a breach or a threatened breach by the Employee of any
such obligation, the Fund shall, in addition to any other rights and remedies
available to it in respect of such breach, be entitled to an injunction from a
court of competent jurisdiction (without any requirement to post bond) granting
it specific performance by the Employee of his or her obligations under this
Section 4.  In the event that the Fund shall file suit to enforce the covenants
contained in this Section 4 (or obtain any other remedy in respect of any breach
thereof), the prevailing party in the suit shall be entitled to recover, in
addition to all other damages to which it may be entitled, the costs incurred by
such party in conducting the suit, including reasonable attorney's fees and
expenses.

           5.  Restrictions on Transfer.
               ------------------------ 

          (a)  Restrictions on Transfer.  The Employee shall not be permitted to

                                                            --              
Expiration Date and (iii) the termination, for any reason, of the Employee's
                     ---

restrictions under Section 5(a) shall terminate with respect to the Options only

          6.  Repurchases by the Company or the Fund Upon Termination of
              ----------------------------------------------------------
Employment or Unforeseen Personal Hardship of the Employee.
- ---------------------------------------------------------- 

          (a)  Termination of Employment.  If, prior to a Public Offering, the
               -------------------------                                      
Employee's active employment with the Company or any Subsidiary thereof that
employs the Employee is terminated for any reason whatsoever, the Company shall
have an option to purchase all or a portion of the Options, to the extent vested
as of the Date of Termination, and/or Exercise Shares then held by the Employee
(or, if his employment was terminated by his death, his estate) (such vested
Options and Exercise Shares, the "Covered Securities") and shall have 60 days
                                  ------------------                         
from the Repurchase Determination Date, or, in the case of any Covered
Securities that are Incentive Stock Options, 30 days from the Repurchase
Determination Date (such 60-day or 30-day period, whichever is applicable, being
hereinafter referred to as the "First Option Period") during which to give
notice in writing to the Employee (or his estate) of its election to exercise or
not to exercise its option to purchase any of the Covered Securities, in whole
or in part.  The Company hereby undertakes to use reasonable efforts to act as
promptly as practicable following the Repurchase Determination Date to make such
election.  If the Company fails to give notice that it intends to exercise its
option to purchase any of the Covered Securities within the First Option Period
or the Company gives notice that it does not intend to exercise such option or
that it intends to exercise such option with respect to only a portion of the
Covered Securities, the Fund shall have the right to purchase all or a portion
of the Covered Securities that will not be repurchased by the Company and shall
have until the expiration of the earlier of 

                                       13
<PAGE>
 
(x) 60 days (or, in the case of any Covered Securities that are Incentive Stock
Options, 30 days) following the last day of the First Option Period or (y) 60
days (or, in the case of any Covered Securities that are Incentive Stock
Options, 30 days) from the date of receipt by the Fund of written notice from
the Company indicating whether it will exercise its option to purchase any of
the Covered Securities (such 60-day or 30-day period, whichever is applicable,
being hereinafter referred to as the "Second Option Period"), to give notice in
writing to the Employee (or his estate) of the Fund's exercise of its option to
purchase any Covered Securities, in whole or in part. If the options of the
Company and the Fund to purchase the Covered Securities pursuant to this Section
6(a) are not exercised with respect to all of the Covered Securities as provided
herein, the Employee (or his estate) shall be entitled to retain the Covered
Securities which will not be so purchased, subject to all of the provisions of
this Agree ment (including without limitation Section 4).

          (b)  Unforeseen Personal Hardship.  In the event that the Employee,
               ----------------------------                                  
while in the employment of the Company or any Subsidiary, experiences Unforeseen
Personal Hardship, the Board will carefully consider any request by the Employee
that the Company repurchase the Employee's Shares, but the Company shall have no
obligation to repurchase such Shares.  The Board shall consider such request
with re  spect to Unforeseen Personal Hardship as soon as practicable after
receipt by the Company of a written request by the Employee, such request to
include sufficient details of the Employee's Unforeseen Personal Hardship to
permit the Board to review the request and the circumstances in an informed
manner.

          (c)  Purchase Price.  All purchases pursuant to this Section 6 by the
               --------------                                                  
Company or the Fund shall be for a purchase price and effected in the manner
prescribed by Sections 6(c) and 6(d).  For purposes of any purchase of Covered
Securities pursuant to this Section 6, the purchase price per Covered Security
to be paid to the Employee (or his estate) for such Covered Security (the
                                                                         
"Purchase Price") shall equal the fair market value (the "Fair Market Value") of
- ---------------                                           -----------------     
a share of Common Stock as of the Repurchase Determination Date or, in the case
of a repurchase of any Shares as a result of Unforeseen Personal Hardship, as of
the date such Shares are repurchased, reduced in the case of the purchase of any
Covered Security that is an Option by the exercise price applicable under such
Option.

          Whenever determination of the Fair Market Value of a share of Common
Stock is required to be made pursuant to this Agreement, such Fair Market Value
shall be such amount as is determined in good faith by the Board on the basis of
an independent valuation of the Common Stock and such other factors as the Board
deems appropriate, including, without limitation, the earnings and certain other
financial and operating information of the Company and its Subsidiaries in
recent periods, the poten-

                                       14
<PAGE>
 
tial value of the Company and its Subsidiaries as a whole, the future prospects
of the Company and its Subsidiaries and the industries in which they compete,
the history and management of the Company and its Subsidiaries, the general
condition of the securities markets, the fair market value of securities of
companies engaged in businesses similar to those of the Company and its
Subsidiaries and the trading price of the Common Stock. The determination of
Fair Market Value will not give effect to any restrictions on transfer of the
Covered Securities, the fact that such Covered Securities would represent a
minority interest in the Company or the fact that the Covered Securities are not
registered for resale under the Securities Act. The Fair Market Value as
determined in good faith by the Board and in the absence of fraud shall be
binding and conclusive upon all parties hereto. If the Company at any time
subdivides (by any stock split, stock dividend or otherwise) the Common Stock
into a greater number of shares, or combines (by reverse stock split or
otherwise) the Common Stock into a smaller number of shares, the Purchase Price
shall be ap propriately adjusted to reflect such subdivision or combination.

          (d)  Closing of Purchase; Payment of Purchase Price.  The closing of a
               ----------------------------------------------

the Company on the tenth business day following whichever of the following is
applicable: (i) the receipt by the Employee (or his estate) of the notice of the
             -                                                                  
Company or the Fund, as the case may be, of its exercise of its option to
purchase any of the Covered Securities pursuant to Section 6(a) or (ii) the
                                                                    --     
Board's determination (which shall be delivered to the Employee) that the
Company is authorized to purchase a stated number of Shares as a result of
Unforeseen Personal Hardship pursuant to Section 6(b).  At the closing, (i) the
                                                                         -     
Company or the Fund, as the case may be, shall pay to the Employee (or his
estate) an amount equal to the Purchase Price and (ii) the Employee (or his
                                                   --

hereby confirm that, pursuant to the Employment Agreement, as of the Effective
Time, each Prior Option to purchase the number of shares of Prior Common Stock
set forth on Schedule A hereto at the exercise price set forth on such Schedule
A was converted into the corresponding Option set forth on Schedule A to
purchase the number of shares of Common Stock at the exercise price per share
set forth on Schedule A.  The Company and the Employee further confirm that only
the Options set forth on Schedule B hereto (the "Incentive Stock Options") are

price paid by the Employee will be taxable to the Employee as ordinary income
pursuant to Section 83 of the Code.

Securities Act or any successor provision)).  Any shares referred to, or covered
by any sale, transfer or dis  tribution referred to, in the preceding sentence
shall not be included in the computation of Qualifying Sale.

          (d)  The Fund acknowledges that the Employee would be irreparably
damaged in the event of a breach or a threatened breach by the Fund of any of
its obligations under this Section 3 and the Fund agrees that, in the event of a
breach or a threatened breach by the Fund of any such obligation, the Employee
shall, in addition to any other rights and remedies available to him or her in
respect of such breach, be entitled to an injunction from a court of competent
jurisdiction (without any requirement to post bond) granting it specific
performance by the Fund of its obligations under this Section 3.  In the event

respect of any breach thereof) and prevails in such suit the Employee shall be
entitled to recover from the Company the costs incurred by the Employee in
conducting the suit, including reasonable attorney's fees and expenses.

Stock owned by the Fund and the Employee to the Take-Along Buyer and another
Take-Along Notice with respect to such Take-Along Offer has not been sent to the
Employee, the Fund shall return to the Employee all certificates representing

completion of such sale and the terms thereof as may reasonably be requested by

          (c)  Effect of Take-Along On Options.

               -------------------------------                                  
     the event of the consummation of a Take-Along Sale, each Option held by the
     Employee immediately prior to the closing of such Take-Along Sale shall be
     canceled in exchange for a payment, in cash, of an amount (such amount, the
     "Cancellation Payment Amount") equal to the product of (i) the excess, if
                                                             -

     Take-Along Sale over the exercise price under such Option, multiplied by
     (ii) the

                                       11
<PAGE>
 
     number of Exercise Shares covered by such Option immediately prior to such
     the consummation of such Take-Along Sale. Payment of the Cancellation
     Payment Amount shall be made as soon as reasonably practicable, but in no
     event later than 30 days, following the closing of the Take-Along Sale.

          (ii)  Alternative Options.  Notwithstanding Section 4(c)(i), no

     settlement or other payment shall be made with respect to any Option in the
     event that the transaction constituting the Take-Along Sale is to be
     accounted for using the "pooling of interest" method of accounting.  In
     such event, each Option held by the Employee immediately prior to the
     closing of the Take-Along Sale shall become fully vested immediately prior
     to the consummation of such transaction and the Employee shall have the
     right, subject to compliance with all applicable securities laws, to (i)
                                                                           -

                                                      --               
     opportunity is made available by the Take-Along Buyer, exchange such
     Options for fully vested options to purchase common stock of the Take-Along
     Buyer (or the direct or indirect parent of the Take-Along Buyer) having
     substantially equivalent economic value to the Options being exchanged
     therefor, as determined by the Board immediately prior to the consummation
     of the Take-Along Sale.  Any Options not exercised or exchanged shall
     expire upon the consummation of the Take-Along Sale.

          (d)  Remedies.  The Employee acknowledges that the Fund would be
               --------                                                   
irreparably damaged in the event of a breach or a threatened breach by the
Employee of any of his obligations under this Section 4 and the Employee agrees
that, in the event of a breach or a threatened breach by the Employee of any
such obligation, the Fund shall, in addition to any other rights and remedies
available to it in respect of such breach, be entitled to an injunction from a
court of competent jurisdiction (without any requirement to post bond) granting
it specific performance by the Employee of his or her obligations under this
Section 4.  In the event that the Fund shall file suit to enforce the covenants
contained in this Section 4 (or obtain any other remedy in respect of any breach
thereof), the prevailing party in the suit shall be entitled to recover, in
addition to all other damages to which it may be entitled, the costs incurred by
such party in conducting the suit, including reasonable attorney's fees and
expenses.

           5.  Restrictions on Transfer.
               ------------------------ 

          (a)  Restrictions on Transfer.  The Employee shall not be permitted to

general partner of any such family partnership, as applicable, shall agree, by
execution of an instrument in form and substance reasonably satisfactory to the
Company, to be bound by all of the provisions of this Agreement.

          (b)  Duration.  The transfer restrictions under Section 5(a) shall
               --------

Expiration Date and (iii) the termination, for any reason, of the Employee's
                     ---

restrictions under Section 5(a) shall terminate with respect to the Options only

          6.  Repurchases by the Company or the Fund Upon Termination of
              ----------------------------------------------------------
Employment or Unforeseen Personal Hardship of the Employee.
- ---------------------------------------------------------- 

          (a)  Termination of Employment.  If, prior to a Public Offering, the
               -------------------------                                      
Employee's active employment with the Company or any Subsidiary thereof that
employs the Employee is terminated for any reason whatsoever, the Company shall
have an option to purchase all or a portion of the Options, to the extent vested
as of the Date of Termination, and/or Exercise Shares then held by the Employee
(or, if his employment was terminated by his death, his estate) (such vested
Options and Exercise Shares, the "Covered Securities") and shall have 60 days
                                  ------------------                         
from the Repurchase Determination Date, or, in the case of any Covered
Securities that are Incentive Stock Options, 30 days from the Repurchase
Determination Date (such 60-day or 30-day period, whichever is applicable, being
hereinafter referred to as the "First Option Period") during which to give
                                -------------------                       
notice in writing to the Employee (or his estate) of its election to exercise or
not to exercise its option to purchase any of the Covered Securities, in whole
or in part.  The Company hereby undertakes to use reasonable efforts to act as
promptly as practicable following the Repurchase Determination Date to make such
election.  If the Company fails to give notice that it intends to exercise its
option to purchase any of the Covered Securities within the First Option Period
or the Company gives notice that it does not intend to exercise such option or
that it intends to exercise such option with respect to only a portion of the
Covered Securities, the Fund shall have the right to purchase all or a portion
of the Covered Securities that will not be repurchased by the Company and shall
have until the expiration of the earlier of

                                       13
<PAGE>
 
(x) 60 days (or, in the case of any Covered Securities that are Incentive Stock
Options, 30 days) following the last day of the First Option Period or (y) 60
days (or, in the case of any Covered Securities that are Incentive Stock
Options, 30 days) from the date of receipt by the Fund of written notice from
the Company indicating whether it will exercise its option to purchase any of
the Covered Securities (such 60-day or 30-day period, whichever is applicable,
being hereinafter referred to as the "Second Option Period"), to give notice in
writing to the Employee (or his estate) of the Fund's exercise of its option to
purchase any Covered Securities, in whole or in part. If the options of the
Company and the Fund to purchase the Covered Securities pursuant to this Section
6(a) are not exercised with respect to all of the Covered Securities as provided
herein, the Employee (or his estate) shall be entitled to retain the Covered
Securities which will not be so purchased, subject to all of the provisions of
this Agree ment (including without limitation Section 4).

          (b)  Unforeseen Personal Hardship.  In the event that the Employee,
               ----------------------------                                  
while in the employment of the Company or any Subsidiary, experiences Unforeseen
Personal Hardship, the Board will carefully consider any request by the Employee
that the Company repurchase the Employee's Shares, but the Company shall have no
obligation to repurchase such Shares.  The Board shall consider such request
with re  spect to Unforeseen Personal Hardship as soon as practicable after
receipt by the Company of a written request by the Employee, such request to
include sufficient details of the Employee's Unforeseen Personal Hardship to
permit the Board to review the request and the circumstances in an informed
manner.

          (c)  Purchase Price.  All purchases pursuant to this Section 6 by the
               --------------                                                  
Company or the Fund shall be for a purchase price and effected in the manner
prescribed by Sections 6(c) and 6(d).  For purposes of any purchase of Covered
Securities pursuant to this Section 6, the purchase price per Covered Security
to be paid to the Employee (or his estate) for such Covered Security (the
                                                                         
"Purchase Price") shall equal the fair market value (the "Fair Market Value") of
- ---------------                                           -----------------     
a share of Common Stock as of the Repurchase Determination Date or, in the case
of a repurchase of any Shares as a result of Unforeseen Personal Hardship, as of
the date such Shares are repurchased, reduced in the case of the purchase of any
Covered Security that is an Option by the exercise price applicable under such
Option.

          Whenever determination of the Fair Market Value of a share of Common
Stock is required to be made pursuant to this Agreement, such Fair Market Value
shall be such amount as is determined in good faith by the Board on the basis of
an independent valuation of the Common Stock and such other factors as the Board
deems appropriate, including, without limitation, the earnings and certain other
financial and operating information of the Company and its Subsidiaries in
recent periods, the poten-

                                       14
<PAGE>
 
tial value of the Company and its Subsidiaries as a whole, the future prospects
of the Company and its Subsidiaries and the industries in which they compete,
the history and management of the Company and its Subsidiaries, the general
condition of the securities markets, the fair market value of securities of
companies engaged in businesses similar to those of the Company and its
Subsidiaries and the trading price of the Common Stock. The determination of
Fair Market Value will not give effect to any restrictions on transfer of the
Covered Securities, the fact that such Covered Securities would represent a
minority interest in the Company or the fact that the Covered Securities are not
registered for resale under the Securities Act. The Fair Market Value as
determined in good faith by the Board and in the absence of fraud shall be
binding and conclusive upon all parties hereto. If the Company at any time
subdivides (by any stock split, stock dividend or otherwise) the Common Stock
into a greater number of shares, or combines (by reverse stock split or
otherwise) the Common Stock into a smaller number of shares, the Purchase Price
shall be appropriately adjusted to reflect such subdivision or combination.

          (d)  Closing of Purchase; Payment of Purchase Price.  The closing of a
               ----------------------------------------------                   
purchase pursuant to this Section 6 shall take place at the principal office of
the Company on the tenth business day following whichever of the following is
applicable: (i) the receipt by the Employee (or his estate) of the notice of the
             -                                                                  
Company or the Fund, as the case may be, of its exercise of its option to
purchase any of the Covered Securities pursuant to Section 6(a) or (ii) the
                                                                    --     
Board's determination (which shall be delivered to the Employee) that the
Company is authorized to purchase a stated number of Shares as a result of
Unforeseen Personal Hardship pursuant to Section 6(b).  At the closing, (i) the
                                                                         -     
Company or the Fund, as the case may be, shall pay to the Employee (or his
estate) an amount equal to the Purchase Price and (ii) the Employee (or his
                                                   --

hereby confirm that, pursuant to the Letter Agreement, as of the Effective Time,
each Prior Option to purchase the number of shares of Prior Common Stock set
forth on Schedule A hereto at the exercise price set forth on such Schedule A
was converted into the corresponding Option set forth on Schedule A to purchase
the number of shares of Common Stock at the exercise price per share set forth
on Schedule A.  The Company and the Employee further confirm that only the
Options set forth on Schedule B hereto (the "Incentive Stock Options") are

Effective Time, in connection with and following the conversion of such Prior
Options described herein, such Options, as so converted, will no longer qualify
as incentive stock options and, as a result, upon the exercise thereof by the
Employee, the excess, if any, of the fair market value (as of the date of
exercise) of the Exercise Shares purchased upon such exercise over the exercise
price paid by the Employee will be taxable to the Employee as ordinary income
pursuant to Section 83 of the Code.

     the event of the consummation of a Take-Along Sale, each Option held by the
     Employee immediately prior to the closing of such Take-Along Sale shall be
     canceled in exchange for a payment, in cash, of an amount (such amount, the

     settlement or other payment shall be made with respect to any Option in the
     event that the transaction constituting the Take-Along Sale is to be
     accounted for using the "pooling of interest" method of accounting.  In
     such event, each Option held by the Employee immediately prior to the
     closing of the Take-Along Sale shall become fully vested immediately prior
     to the consummation of such transaction and the Employee shall have the
     right, subject to compliance with all applicable securities laws, to (i)

     therefor, as determined by the Board immediately prior to the consummation
     of the Take-Along Sale.  Any Options not exercised or exchanged shall
     expire upon the consummation of the Take-Along Sale.

          (d)  Remedies.  The Employee acknowledges that the Fund would be

available to it in respect of such breach, be entitled to an injunction from a

addition to all other damages to which it may be entitled, the costs incurred by
such party in conducting the suit, including reasonable attorney's fees and

Covered Securities pursuant to this Section 6(a) are not exercised with respect
to all of the Covered Securities as provided herein, the Employee (or his
estate) shall be entitled to retain the Covered Securities which will not be so

Stock is required to be made pursuant to this Agreement, such Fair Market Value
shall be such amount as is determined in good faith by the Board on the basis of
an independent valuation of the Common Stock and such other factors as the Board
deems appropriate, including, without limitation, the earnings and certain other
financial and operating information of the Company and its Subsidiaries in
recent per  iods, the potential value of the Company and its Subsidiaries as a
whole, the future prospects of the Company and its Subsidiaries and the
industries in which they compete, the history and management of the Company and
its Subsidiaries, the general condition of the securities markets, the fair
market value of securities of companies engaged in businesses similar to those
of the Company and its Subsidiaries and the trading price of the Common Stock.
The determination of Fair Market Value will not give effect to any restrictions
on transfer of the Covered Securities, the fact that such Covered Securities
would represent a minority interest in the Company or the fact that the Covered
Securities are not registered for resale under the Securities Act.  The Fair
Market Value as determined in good faith by the Board and in the absence of
fraud shall be binding and conclusive upon all parties hereto.  If the Company
at any time subdivides (by any stock split, stock dividend or otherwise) the
Common Stock into a greater number of shares, or combines (by reverse stock
split or otherwise) the Common Stock into a smaller number of shares, the
Purchase Price shall be ap  propriately adjusted to reflect such subdivision or
combination.

Board's determination (which shall be delivered to the Employee) that the
Company is authorized to purchase a stated number of Shares as a result of
Unforeseen Personal Hardship pursuant to Section 6(b).  At the closing, (i) the

register any of its equity securities under the Securities Act, whether or not
for its own account (other than pursuant to a Special Registration), the
Employee agrees not to effect (other than pursuant to such registration) any
public sale or distribution, including, but not limited to, any sale pursuant to
Rule 144 or Rule 144A, of any Shares, any other equity securities of the Company
or any securities convertible into or exchangeable or exercisable for any equity
