      5. Registration Rights.
         -------------------
 
         5.1. Secondary Registration.
              ----------------------
   
            (a) REGISTRATION FOR RESALE. The Corporation intends to seek to
create liquidity for the Shares held by the Executive prior to the Expiration
Date. In the sole discretion of the Corporation, the Corporation may file with
the Securities and Exchange Commission (the "Commission") a Registration
Statement on Form S-8 or Form S-3 (or similar form) sufficient to permit the
public offering and sale of the Registrable Shares (as defined below) through
all securities exchanges and over-the-counter markets on which the Corporation's
Common Stock is then traded. For the purposes of this Agreement, "Registrable
Shares" shall mean outstanding Shares and Shares issuable upon exercise of
then-exercisable options held by the Executive and any other person holding
registration rights substantially the same as the rights set forth in this
Section 5, which Shares are not at that time the subject of an effective
registration statement filed with the Commission. For the purposes of this
Agreement, "Holders" shall mean all persons holding Registrable Shares.
 
            (b) NOTICE OF FILING OF REGISTRATION STATEMENT. In the event the
Corporation determines to file a registration pursuant to Section 5.1(a), the
Corporation shall notify each Holder of the proposed filing and request that
each Holder notify the Corporation within 15 days thereafter of the number of
Registrable Shares such Holder wishes the Corporation to register on such
Holder's behalf. Each Holder shall, prior to the end of such 15 day period,
request in writing that the Corporation register the sale of all or part of such
Holder's Registrable Shares.
 
         5.2. Piggyback Registration Rights.
              -----------------------------
 
              (a) OFFER TO INCLUDE REGISTRABLE SHARES IN CORPORATION OFFERING. 
If, at any time prior to the Expiration Date, the Corporation shall file a
registration statement to register shares of Common Stock for its own account in
an underwritten offering with the Commission while any Registrable Shares are
outstanding, the Corporation shall give all the Holders at least 45 days prior
written notice of the filing of such registration statement. Subject to 5.2(b)
below, if requested by any Holder in writing within 30 days after receipt of any
such notice, the
 
 
 
                                      - 6 -
 
 
<PAGE>   7
 
 
Corporation shall register or qualify all or, at each Holder's option, any
portion of the Registrable Shares of any Holders who shall have made such
request, concurrently with the registration of such other securities, all to the
extent requisite to permit the public offering and sale of the Registrable
Shares through the facilities of all appropriate securities exchanges and the
over-the-counter market, and will use its best efforts through its officers,
directors, auditors, and counsel to cause such registration statement to become
effective as promptly as practicable.
 
               (b) CUTBACK OF PARTICIPATION IN CORPORATION OFFERING.
Notwithstanding Section 5.2(a), if the managing underwriter of any such offering
shall advise the Corporation in writing that, in its opinion, the distribution
of all or a portion of the Registrable Shares requested to be included in the
registration concurrently with the securities being registered by the
Corporation would materially adversely affect the distribution of such
securities by the Corporation for its own account, then the number of
Registrable Shares held by such Holder to be included in such registration
statement shall be reduced to the extent advised by such managing underwriter,
provided that any such reduction shall be made pro rata among the Holders
electing to participate in such registration based on the aggregate number of
Registrable Shares held by each Holder electing to so participate, and provided
further that the total number of Registrable Shares included in any such
registration shall not be less than 25% of the total number of shares of Common
Stock included in the registration for the Corporation's account, the Holders
account and the account of any other person.
 
         5.3. Underwriting.
              ------------
 
            (a) UNDERWRITING IN SECONDARY REGISTRATION. If the Corporation
undertakes a registration under Section 5.1, any Holder wishing to distribute
the Registrable Shares which such Holder has requested to be registered in such
registration by means of an underwriting, such Holder shall so advise the
Corporation in such Holder's request to participate in such registration under
Section 5.1(b). The Holders of a majority of the Registrable Shares being
offered may select one or more underwriters for the registration under Section
5.1, which selection shall be approved by the Corporation, which approval shall
not be unreasonably withheld provided such underwriter(s) are experienced and
reputable. The Corporation shall, together with the Holders engaged in the
registration hereunder, enter into an underwriting agreement with the
representative of the underwriter or underwriters selected for such underwriting
in accordance with this Section 5.3(a).
 
            (b) UNDERWRITING IN PIGGYBACK REGISTRATION. In the event of an
underwritten registration pursuant to the provisions of Section 5.2, any Holder
who requests to have Registrable Shares included in such registration shall
enter into such custody agreements and powers of attorney as are reasonably
requested by the Corporation and any such underwriter, and, if requested, enter
into an underwriting agreement containing customary terms.
 
            (c) RIGHT OF WITHDRAWAL FROM UNDERWRITING. In the event of an
underwritten offering under Section 5.3(a) or (b), the right of a Holder to
participate
 
 
                                      - 7 -
 
 
<PAGE>   8
 
 
in a registration hereunder shall be conditioned upon the inclusion of such
Holder's Registrable Shares in such underwriting. If a Holder disapproves of the
terms of the underwriting, such Holder may elect to withdraw therefrom by
written notice to the Corporation and the underwriter delivered at least seven
days prior to the effective date of the Registration Statement. The securities
so withdrawn shall also be withdrawn from the Registration Statement.
 
            5.4. EFFECTIVENESS AND EXPENSES. The Corporation will use its best
efforts through its officers, directors, auditors and counsel to cause any
Registration Statement filed pursuant to this Section 5 to become effective as
promptly as practicable. The Corporation shall be obligated to use its best
efforts to maintain the effectiveness of such Registration Statement only until
the earlier of (i) the Expiration Date, and (ii) the date on which no
Registrable Shares remain outstanding (the "Registration Termination Date"). The
Corporation shall be obligated to pay all expenses (other than the fees and
disbursements of counsel for the Holders and underwriting discounts, if any,
payable in respect of the Registrable Shares sold by the Holders) in connection
with any such registration statement.
 
            5.5. BLUE SKY REGISTRATIONS. In the event of a registration pursuant
to the provisions of this Section 5, the Corporation shall use its best efforts
to cause the Registrable Shares so registered to be registered or qualified for
sale under the securities or blue sky laws of such jurisdictions as the Holders
may reasonably request; provided, however, that the Corporation shall not be
required to qualify to do business in any state by reason of this Section 5.5 in
which it is not otherwise required to qualify to do business.
 
            5.6. CONTINUING EFFECTIVENESS. Until the Registration Termination
Date, the Corporation shall use its best efforts to keep effective any
registration or qualification contemplated by this Section 5 and shall from time
to time amend or supplement each applicable registration statement, preliminary
prospectus, final prospectus, application, document and communication for such
period of time as shall be required to permit the Holders to complete the offer
and sale of the Registrable Shares covered thereby.
 
            5.7. COPIES OF REGISTRATION STATEMENT AND RELATED DOCUMENTS. In the
event of a registration pursuant to the provisions of this Section 5, the
Corporation shall furnish to each Holder a copy of the Registration Statement
and of each amendment and supplement thereto (in each case, including all
exhibits), and a reasonable number of copies of each prospectus contained in
such registration statement and each supplement or amendment thereto (including
each preliminary prospectus), all of which shall conform to the requirements of
the Act, and the rules and regulations thereunder, and such other documents, as
any Holder may reasonably request to facilitate the disposition of the
Registrable Shares included in such registration.
 
            5.8. RULE 144 ELIGIBILITY.  The Corporation agrees that, following 
the Expiration Date, until all the Registrable Shares have been sold under a
registration statement or pursuant to Rule 144 under the Act, the Corporation
shall use its best
 
 
 
                                      - 8 -
 
 
<PAGE>   9
 
 
efforts to keep current in filing all reports, statements and other materials
required to be filed with the Commission to permit holders of the Registrable
Shares to sell such securities under Rule 144.
 
      6. Indemnity.
         ---------
 
         6.1. CORPORATION INDEMNIFICATION OF THE HOLDERS. Subject to the 
conditions set forth below, the Corporation agrees to indemnify and hold
harmless each Holder, its officers, directors, partners, employees, agents and
counsel, and each person, if any, who controls any such person within the
meaning of Section 15 of the Act or Section 20(a) of the Securities Exchange Act
of 1934, as amended (the "Exchange Act"), from and against any and all loss,
liability, charge, claim, damage and expense whatsoever (which shall include,
for all purposes of this Section 6, without limitation, attorneys' fees and any
and all expenses whatsoever incurred in investigating, preparing or defending
against any litigation, commenced or threatened, or any claim whatsoever, and
any and all amounts paid in settlement of any claim or litigation), as and when
incurred, arising out of, based upon, or in connection with any untrue statement
or alleged untrue statement of a material fact contained in any registration
statement, preliminary prospectus or final prospectus (as from time to time
amended and supplemented), or any amendment or supplement thereto, relating to
the sale of any of the Registrable Shares, filed with the Commission or any
securities exchange; or any omission or alleged omission to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading, unless such statement or omission was made in reliance upon and
in conformity with written information furnished to the Corporation with respect
to such Holder by or on behalf of such person expressly for inclusion in any
registration statement, preliminary prospectus, or final prospectus, or any
amendment or supplement thereto, as the case may be. The foregoing agreement to
indemnify shall be in addition to any liability the Corporation may otherwise
have, including liabilities arising under this Agreement.
 
      If any action is brought against any Holder or any of its officers,
directors, partners, employees, agents or counsel, or any controlling persons of
such person (an "Indemnified Party") in respect of which indemnity may be sought
against the Corporation pursuant to the foregoing paragraph, such Indemnified
Party or Parties shall promptly notify the Corporation in writing of the
institution of such action (but the failure so to notify shall not relieve the
Corporation from any liability other than pursuant to this Section 6.1) and the
Corporation shall promptly assume the defense of such action, including the
employment of counsel (reasonably satisfactory to such Indemnified Party or
parties) and payment of expenses. Such Indemnified Party or parties shall have
the right to employ its or their own counsel in any such case, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party or
parties unless the employment of such counsel shall have been authorized in
writing by the Corporation in connection with the defense of such action or the
Corporation shall not have promptly employed counsel reasonably satisfactory to
such Indemnified Party or Parties to have charge of the defense of such action
or such Indemnified Party or parties shall have reasonably concluded that there
may be one or more legal defenses available to it or them or to other
indemnified parties which are different from or
 
 
 
 
                                      - 9 -
 
 
<PAGE>   10
 
 
additional to those available to the Corporation, in any of which events such
fees and expenses shall be borne by the Corporation, and the Corporation shall
not have the right to direct the defense of such action on behalf of the
Indemnified Party or Parties. Anything in this Section 5 to the contrary
notwithstanding, the Corporation shall not be liable for any settlement of any
such claim or action effected without its written consent, which shall not be
unreasonably withheld. The Corporation shall not, without the prior written
consent of each Indemnified Party that is not released as described in this
sentence, settle or compromise any action, or permit a default or consent to the
entry of judgment in or otherwise seek to terminate any pending or threatened
action, in respect of which indemnity may be sought hereunder (whether or not
any Indemnified Party is a party thereto), unless such settlement, compromise,
consent or termination includes an unconditional release of each Indemnified
Party from all liability in respect of such action. The Corporation agrees
promptly to notify the Holders of the commencement of any litigation or
proceedings against the Corporation or any of its officers or directors in
connection with the sale of any Registrable Shares or any preliminary
prospectus, prospectus, registration statement or amendment or supplement
thereto, or any application relating to any sale of any Registrable Shares.
 
         6.2. HOLDER INDEMNIFICATION OF THE CORPORATION. Each Holder 
participating in any such registration shall indemnify and hold harmless the
Corporation, each director of the Corporation, each officer of the Corporation
who shall have signed the registration statement covering Registrable Shares
held by the Holder, each other person, if any, who controls the Corporation
within the meaning of Section 15 of the Act or Section 20(a) of the Exchange
Act, and its or their respective counsel, to the same extent as the foregoing
indemnity from the Corporation to the Holders in Section 6.1, but only with
respect to statements or omissions, if any, made in any registration statement,
preliminary prospectus or final prospectus (as from time to time amended and
supplemented), or any amendment or supplement thereto, in reliance upon and in
conformity with written information furnished to the Corporation with respect to
such Holder by or on behalf of such Holder expressly for inclusion in any such
registration statement, preliminary prospectus or final prospectus, or any
amendment or supplement thereto, as the case may be. If any action shall be
brought against the Corporation or any other person so indemnified based on any
such registration statement, preliminary prospectus or final prospectus, or any
amendment or supplement thereto, or in any application, and in respect of which
indemnity may be sought against such Holder pursuant to this Section 6.2, such
Holder shall have the rights and duties given to the Corporation and the
Corporation and each other person so indemnified shall have the rights and
duties given to the indemnified parties, by the provisions of Section 6.1.
 
         6.3. CONTRIBUTION. To provide for just and equitable contribution, if 
(i) an Indemnified Party makes a claim for indemnification pursuant to Section
6.1 or 6.2 but it is found in a final judicial determination, not subject to
further appeal, that such indemnification may not be enforced in such case, even
though this Agreement expressly provides for indemnification in such case, or
(ii) any indemnified or indemnifying party seeks contribution under the Act, the
Exchange Act or otherwise, then the Corporation (including for this purpose any
contribution made by or on behalf
 
 
 
                                     - 10 -
 
 
<PAGE>   11
 
 
of any director of the Corporation, any officer of the Corporation who signed
any such registration statement, any controlling person of the Corporation, and
its or their respective counsel), as one entity, and the Holders of the
Registrable Shares included in such registration in the aggregate (including for
this purpose any contribution by or on behalf of an Indemnified Party), as a
second entity, shall contribute to the losses, liabilities, claims, damages and
expenses whatsoever to which any of them may be subject, on the basis of
relevant equitable considerations such as the relative fault of the Corporation
and such Holders in connection with the facts which resulted in such losses,
liabilities, claims, damages and expenses. The relative fault, in the case of an
untrue statement, alleged untrue statement, omission or alleged omission, shall
be determined by, among other things, whether such statement, alleged statement,
omission or alleged omission relates to information supplied by the Corporation
or by such Holders, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement, alleged
statement, omission or alleged omission. The Corporation and the Holder agree
that it would be unjust and inequitable if the respective obligations of the
Corporation and the Holders for the contribution were determined by pro rata or
per capita allocation of the aggregate losses, liabilities, claims, damages and
expenses (even if the Holder and the other indemnified parties were treated as
one entity for such purpose) or by any other method of allocation that does not
reflect the equitable considerations, referred to in this Section 6.3. In no
case shall any Holder be responsible for a portion of the contribution
obligation imposed on all Holders in excess of its pro rata share based on the
number of Registrable Shares of by it and included in such registration as
compared to the number of Registrable Shares owned by all Holders and included
in such registration. No person guilty of a fraudulent misrepresentation (within
the meaning of Section 11(f) of the Act) shall be entitled to contribution from
any person who is not guilty of such fraudulent misrepresentation. For purposes
of this Section 6.3, each person, if any, who controls any Holder within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act and each
officer, director, partner, employee, agent and counsel of each such Holder or
control person shall have the same rights to contribution as such Holder or
control person and each person, if any, who controls the Corporation within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, each
officer of the Corporation who shall have signed any such registration
statement, each director of the Corporation and its or their respective counsel
shall have the same right to contribution as the Corporation, subject in each
case to the provisions of this Section 6.3. Anything in this Section 6.3 to the
contrary notwithstanding, no party shall be liable for contribution with respect
to the settlement of any claim or action effected without its written consent.
This Section 6.3 is intended to supersede any right to contribution under the
Act, the Exchange Act or otherwise.
