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

                                      -3-
<PAGE>

                    (i)  Request for Registration. Subject to the terms hereof,
the Initiating Holders may make a demand in writing for registration under the
Securities Act of all or part of their Registrable Securities (the "Demand
Registration"). The Holders shall be entitled to one (1) Demand Registration. If
the Corporation receives from the Initiating Holders a written request that the
Corporation effect a registration under the Securities Act of Registrable
Securities, the Corporation will:

                         (A)  promptly give written notice of the proposed
registration, qualification or compliance to all of the other Holders; and

                         (B)  as soon as reasonably practicable, use its best
efforts to effect such registration, qualification or compliance (including,
without limitation, appropriate qualification under applicable "blue sky" or
other state securities laws and appropriate compliance with applicable
regulations issued under the Securities Act and any other governmental
requirements or regulations) as may be so requested and as would permit or
facilitate the sale and distribution of all of such Registrable Securities as
are specified in such request; provided, however, that the Corporation shall not
be obligated to take any action to effect any such registration, qualification
or compliance pursuant to this Section 1.3(a)(i):

                              (i)  in any particular jurisdiction in which the
Corporation would be required to execute a general consent to service of process
in effecting such registration, qualification or compliance unless the
Corporation is already subject to service in such jurisdiction and except as may
be required by the Securities Act; and

                              (ii) after all of the Registrable Securities are
freely saleable without restrictions.

          In the event that a request for registration is made pursuant to this
Section 1.3(a)(i) but the Corporation is not obligated to effect such requested
registration by virtue of the foregoing clauses (B)(i) and (B)(ii), such request
shall not be deemed to be a Demand Registration for purposes of this Section
1.3(a)(i). Subject to the foregoing clauses (B)(i) and (B)(ii), the Corporation
shall prepare and file a Registration Statement covering the Registrable
Securities so requested to be registered immediately after receipt of the
request or requests of the Initiating Holders.

                    (ii) Underwriting. If the Initiating Holders intend to
distribute the Registrable Securities covered by their request by means of an
underwriting, they shall so advise the Corporation as a part of their request
made pursuant to Section 1.3(a)(i) hereof and the Corporation shall include such
information in the written notice referred to in Section 1.3(a)(i) hereof. In
such event, the right of any Holder to participate in such registration shall be
conditioned upon such Holder's participation in the underwriting arrangements
required by this Section 1.3(a)(i), and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent requested shall be
limited to the extent provided herein.

          The Corporation shall (together with all Holders proposing to
distribute their securities through such underwriting) enter into an
underwriting agreement in customary form (but subject to the reasonable approval
of the Holders holding a majority of the Registrable

                                      -4-
<PAGE>

Securities to be included in such underwriting) with the managing underwriter
selected for such underwriting by the Holders holding a majority of the
Registrable Securities to be included in such underwriting, which managing
underwriter shall be reasonably acceptable to the Corporation. The Corporation
and the Holders participating in such underwriting shall reasonably cooperate
with any such underwriter. Notwithstanding any other provision of this Section
1.3, if the managing underwriter advises the Initiating Holders in writing that,
in its good faith judgment, marketing factors require a limitation of the number
of Shares to be underwritten, then the Corporation shall so advise all
participating Holders and the number of shares of Registrable Securities that
may be included in the registration and underwriting shall be allocated among
all Holders pro rata on the basis of the amounts of Registrable Securities held
by such Holders at the time of filing the Registration Statement shall be
included in such Registration Statement. No Registrable Securities excluded from
the underwriting by reason of the underwriter's marketing limitation shall be
included in such registration. If the underwriter has not limited the number of
Registrable Securities to be underwritten, the Corporation may include
securities for its own account (or for the account of other shareholders in
accordance with the terms of this Agreement) in such registration if the
underwriter so agrees and if the number of Registrable Securities that would
otherwise have been included in such registration and underwriting will not
thereby be limited.

          If the number of Registrable Securities excluded from the underwriting
exceeds fifty percent (50%) of the total Registrable Securities requested to be
included in such underwriting by the Holders, then Holders of a majority of the
Registrable Securities requested to be included in such underwriting may elect
to terminate the registration.

               (b)  Unlimited Piggyback Registration Rights.

                    (i)  Notice of Registration. If the Corporation at any time
proposes to file a registration statement with respect to any class of equity
securities, whether for its own account (other than in connection with the
Registration Statement contemplated by Section 1.3(a) hereof or a registration
statement on Form S-8 (or any successor or substantially similar form) relating
to an employee stock option, stock purchase or compensation plan or securities
issued or issuable pursuant to any such plan), or a registration statement on
Form S-4 (or any successor or substantially similar form) or for the account of
a holder of securities of the Corporation, other than for the registration of
securities for sale on a continuous or delayed basis pursuant to Rule 415, then
the Corporation will:

                         (A)  promptly give to each Holder written notice
thereof at least twenty (20) days before the anticipated initial filing date of
any such registration statement, and such notice shall offer to all Holders the
opportunity to have any or all of the Registrable Securities held by such
Holders included in such registration statement; and

                         (B)  include in such registration statement (and any
related qualification under "blue sky" laws or other compliance), and in any
underwriting involved therein, (A) all the Registrable Securities specified in a
written request or requests to be included therein, made within twenty (20) days
after receipt of such written notice from the Corporation, by any Holder.

                                      -5-
<PAGE>

          Subject to the underwriter limitations, if any, described in Section
1.3(b)(iii) below, each Holder shall be entitled to have its Registrable
Securities included in an unlimited number of registrations pursuant to this
Section 1.3(b)(i).

          No right to registration of Registrable Securities under this Section
1.3(b)(i) shall be construed to limit any registration required under Section
1.3(a).

                    (ii)  Holdback by the Corporation. If the Corporation has
previously filed a Registration Statement with respect to Registrable Securities
pursuant to Section 1.3(a), and if such previous registration has not been
withdrawn or abandoned, the Corporation will not file or cause to be effected
any other registration of any of its equity securities or securities convertible
or exchangeable into or exercisable for its equity securities under the
Securities Act (except for a registration relating solely to employee benefits
plans or to a transaction under Rule 145), whether on its own behalf or at the
request of any holder or holders of such securities, until a period of ninety
(90) days has elapsed from the effective date of such a previous registration.

                    (iii) Underwriting. If the registration of which the
Corporation gives notice is for a registered public offering involving an
underwriting, the Corporation shall so advise the Holders as a part of the
written notice given pursuant to Section 1.3(b)(i)(A). In such event the right
of any Holder to registration pursuant to this Section 1.3(b) shall be
conditioned upon such Holder's participation in such underwriting to the extent
provided herein. All Holders proposing to distribute their securities through
such underwriting shall (together with the Corporation and the other Holders
distributing their securities through such underwriting) enter into an
underwriting agreement in customary form with the managing underwriter selected
for such underwriting by the Corporation, but subject to the reasonable approval
of Holders holding a majority of the Registrable Securities to be included in
such registration. Notwithstanding any other provision of this Section 1.3(b),
if the managing underwriter determines in its good faith judgment that marketing
factors require limitation of the number of shares to be underwritten, the
managing underwriter may limit the Registrable Securities to be included in such
registration. The Corporation shall so advise all Holders and the number of
shares of securities that may be included in the registration and underwriting
(other than in behalf of the Corporation) shall first be allocated among all
Holders pro rata on the basis of the amounts of Registrable Securities held by
such Holders at the time of filing of the registration statement; provided,
however, unless otherwise agreed upon by the Holders of a majority of the
Registrable Securities desiring to participate in the offering, in no event
shall the amount of Registrable Securities of the Holders included in the
offering be reduced below thirty percent (30%) of the total amount of securities
included in such offering. No securities of the Corporation held by parties
other than the Holders or the Corporation shall be included in any registration
and underwriting to which this section applies if the number of Registrable
Securities that would otherwise have been included in such registration and
underwriting will thereby be limited. If any Holder disapproves of the terms of
any such underwriting, he may elect to withdraw therefrom by written notice to
the Corporation and the managing underwriter.

          1.4  Limitations on Subsequent Registration Rights. From and after the
date hereof, without the approval of the Holders of a majority of the
Registrable Securities, the Corporation shall not enter into any agreement
granting any holder or prospective holder of any

                                      -6-
<PAGE>

securities of the Corporation registration rights with respect to such
securities unless: (a) the agreement does not allow the holder to include the
securities in a registration filed under Section 1.3(b) hereof unless it would
not thereby limit the number of Registrable Securities of the Holders included
in the registration; and (b) the agreement does not grant rights which would
delay the ability of the Holders to obligate the Corporation to file a
registration statement on the Holders' behalf pursuant to Sections 1.2 or 1.3.
Except as set forth in section 1.11, the Corporation has not previously and
shall not in the future enter into any agreement, arrangement or understanding
with respect to its securities which is inconsistent with the rights granted to
the Holders of Registrable Securities in this Agreement or otherwise conflicts
with the provisions hereof.

          1.5  Expenses of Registration. All Registration Expenses shall be
borne by the Corporation, except as otherwise provided in Section 1.3(a)(ii).
All Selling Expenses relating to securities registered on behalf of the Holders
shall be borne by the Holders of such securities pro rata on the basis of the
number of shares so registered.

          1.6  Registration Procedures. In the case of each registration,
qualification or compliance effected by the Corporation pursuant to this Section
1, the Corporation will keep each Holder advised in writing as to the initiation
of each registration and such amendment thereof and as to the completion
thereof. At its expense the Corporation will:

               (a)  Promptly prepare and file with the Commission a Registration
Statement with respect to such securities and use its best efforts to cause such
Registration Statement to become effective as promptly as possible and remain
effective until the earlier of (i) the date which is one hundred and eighty
(180) days after the effective date of such Registration Statement and (ii) the
date on which all Registrable Securities covered by such Registration Statement
have been sold and the distribution contemplated thereby has been completed (the
"Registration Period"); provided, however, that if, after such Registration
Statement has become effective, the offering of the Registrable Securities
pursuant to such registration is interfered with by any stop order, injunction
or similar order of the Commission or other governmental agency or court (other
than by reason of any untrue statement of a material fact or any omission of a
material fact required to be stated in the Registration Statement or necessary
to make the statements therein not misleading, to the extent, but only to the
extent, that such untrue statement or omission is contained in any information
or affidavit furnished in writing by a Holder to the Corporation specifically
for inclusion therein), such registration will be deemed not to have been
effected. Notwithstanding the foregoing, if within sixty (60) days after the
effective date of the stop order, injunction or similar order of the Commission
or other governmental agency or court, the same is lifted and the effectiveness
of the registration is restored, the registration shall be deemed to have been
effected, provided, that the Registration Period (i) will be tolled during the
period the stop order, injunction or similar order is in effect, (ii) shall
resume upon the lifting thereof and (iii) shall be extended one day for each day
during the period that the stop order, injunction or similar order is in effect.

               (b)  Furnish, at least five (5) business days before filing a
Registration Statement that registers such Registrable Securities, a prospectus
relating thereto and any amendments or supplements relating to such a
Registration Statement or prospectus, to one counsel selected by the Holders
(the "Holders' Counsel"), copies of all such documents proposed

                                      -7-
<PAGE>

to be filed (it being understood that such five-business-day period need not
apply to successive drafts of the same document proposed to be filed so long as
such successive drafts are supplied to the Holders' Counsel in advance of the
proposed filing by a period of time that is customary and reasonable under the
circumstances).

               (c)  Prepare and file with the Commission such amendments and
supplements to such Registration Statement and the prospectus used in connection
with such Registration Statement as may be necessary to keep such Registration
Statement effective for the Registration Period, and to comply with the
provisions of the Securities Act with respect to the sale and other disposition
of all securities covered by such Registration Statement.

               (d)  Notify in writing to the Holders' Counsel promptly (i) of
the receipt by the Corporation of any notification with respect to any comments
by the Commission with respect to such Registration Statement or prospectus or
any amendment or supplement thereto or any request by the Commission for the
amending or supplementing thereof or for additional information with respect
thereto, (ii) of the receipt by the Corporation of any notification with respect
to the issuance by the Commission of any stop order suspending the effectiveness
of such Registration Statement or prospectus or any amendment or supplement
thereto or the initiation or threatening of any proceeding for that purpose and
(iii) of the receipt by the Corporation of any notification with respect to the
suspension of the qualification of such Registrable Securities for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purposes.

               (e)  Use its best efforts to register and qualify the securities
covered by such Registration Statement under such other securities or "blue sky"
laws of such jurisdictions as shall be reasonably requested by the Holders,
provided that the Corporation shall not be required in connection therewith or
as a condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.

               (f)  Furnish to the Holders participating in such registration
and to the underwriters of the securities being registered such number of copies
of the Registration Statement, preliminary prospectus, final prospectus and such
other documents as such Holders or underwriters may reasonably request in order
to facilitate the public offering of such securities.

               (g)  In the event of any underwritten public offering, enter into
and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

               (h)  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 of the happening of any event
as a result of which 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 not misleading in the light of the circumstances then
existing.

                                      -8-
<PAGE>

               (i)  Use its best efforts to furnish, at the request of any
Holder requesting registration of Registrable Securities pursuant to this
Section 1, on the date that such Registrable Securities are delivered to the
underwriters for sale in connection with a registration pursuant to this Section
1, if such securities are being sold through underwriters, or, if such
securities are not being sold through underwriters, on the date that the
Registration Statement with respect to such securities becomes effective, (i) a
copy addressed to Holders of the opinion, dated such date, of the counsel
representing the Corporation for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and (in a non-underwritten
offering) to the Holders requesting registration of Registrable Securities and
(ii) a copy addressed to Holders of the letter dated such date, from the
independent certified public accountants of the Corporation, in form and
substance as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering, addressed to the underwriters,
if any, and (in a non-underwritten offering) to the Holders requesting
registration of Registrable Securities.

               (j)  List such Registrable Securities on any national securities
exchange on which any shares of the Common Stock are listed or, if the Common
Stock is not listed on a national securities exchange, use its best efforts to
qualify such Registrable Securities on the American Stock Exchange or such other
national securities exchange as the Corporation shall determine, subject to the
approval by the Holders of a majority of the Registrable Securities included in
the registration, which approval the Holders shall not unreasonably withhold.

               (k)  Otherwise use its best efforts to comply with all applicable
rules and regulations of the Commission and the securities commission or other
regulatory authority of any relevant state or other jurisdiction and make
available to its securityholders, as soon as reasonably practicable, earnings
statements (which need not be audited) covering a period of 12 months beginning
within three months after the effective date of the Registration Statement,
which earnings statements shall satisfy the provisions of Section 11(a) of the
Securities Act.

               (l)  Use its best efforts to take all other steps reasonably
necessary to effect the registration of such Registrable Securities contemplated
hereby.

          1.7  Indemnification.
               ---------------

               (a)  The Corporation will indemnify each Holder; each Holder's
officers, directors, employees, principals, equity holders and partners; each
underwriter, broker or any other Person (other than the Corporation) acting on
behalf of such Holder, and each Person (other than the Corporation) controlling
such Person within the meaning of Section 15 of the Securities Act, with respect
to which registration, qualification or that compliance has been effected
pursuant to this Section 1, against all expenses, claims, losses, damages or
liabilities, joint or several (or actions in respect thereof) (collectively,
"Losses"), including any of the foregoing incurred in settlement of any
litigation, commenced or threatened, arising out of or (i) based on any untrue
statement (or alleged untrue statement) of a material fact contained in any
Registration Statement, preliminary or final prospectus, offering circular or
other document, or any amendment or supplement thereto, incident to any such
registration, qualification or compliance, or (ii) based on any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein, in light of the

                                      -9-
<PAGE>

circumstances in which they were made, not misleading, or (iii) any violation by
the Corporation of the Securities Act, state securities or "blue sky" laws or
any rule or regulation promulgated thereunder applicable to the Corporation in
connection with any such registration, qualification or compliance (each
statement, omission or violation referred to in clauses (i), (ii) and (iii) of
this Section 1.7(a) being referred to as a "Violation"), and the Corporation
will reimburse each such Holder, each of its officers and directors, each such
underwriter, broker or other Person (other than the Corporation) acting on
behalf of such Holder, and each such controlling Person (other than the
Corporation) for any legal and any other expenses reasonably incurred in
connection with investigating, preparing or defending any such Loss, provided
that the Corporation will not be liable to any such Person in any such case to
the extent, but only to the extent, that any such Loss arises out of or is based
on any untrue statement or omission (or alleged untrue statement or omission),
made in conformity with written information which relates to such Person
furnished to the Corporation by an instrument duly executed by such Holder,
underwriter or controlling Person and stated to be specifically for use therein
or the preparation thereby.

               (b)  Each Holder will, if Registrable Securities held by such
Holder are included, in the securities as to which such registration,
qualification or compliance is being effected, indemnify the Corporation, each
of its directors and officers, each underwriter, broker or other Person acting
on behalf of the Holders, and each Person who controls any of the foregoing
Persons within the meaning of Section 15 of the Securities Act, and each other
such Holder, each of its officers and directors and each person controlling such
Holder within the meaning of Section 15 of the Securities Act, against all
Losses arising out of any untrue statement (or alleged untrue statement) of a
material fact contained in any such Registration Statement, preliminary or final
prospectus, offering circular or other document, or any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse the
Corporation, such Holders, such directors, officers, underwriters, brokers,
other Persons acting on behalf of the Holders or control Persons for any legal
or any other expenses reasonably incurred in connection with investigating,
preparing or defending any such Loss, in each case to the extent, but only to
the extent, that such loss arises out of or based upon an untrue statement (or
alleged untrue statement) or omission (or alleged omission) made in such
Registration Statement, preliminary or final prospectus, offering circular or
other document in conformity with written information furnished to the
Corporation by an instrument duly executed by such Holder and stated to be
specifically for use therein or the preparation thereby. Notwithstanding the
foregoing, the liability of each Holder under this subsection (b) shall be
limited to an amount equal to the aggregate proceeds received by such Holder
from the sale of Registrable Securities in such registration.

               (c)  Each Person entitled to indemnification under this Section
1.7 (the "Indemnified Party") shall give notice to the Party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not unreasonably be
withheld), and the Indemnified Party may participate in such defense at such
Indemnified Party's expense, and provided further, that the failure of any
Indemnified Party to give notice as provided herein shall

                                     -10-
<PAGE>

not relieve the Indemnifying Party of its obligations under this Section 1.7
unless the failure to give such notice is materially prejudicial to an
Indemnifying Party's ability to defend such action and provided further, that
the Indemnifying Party shall not assume the defense for matters as to which
there is a conflict of interest or separate and different defenses. If (i) the
Indemnifying Party shall have failed to assume the defense of such claim and to
employ counsel reasonably satisfactory to the Indemnified Party in a timely
manner or (ii) in the reasonable judgment of any Indemnified Party a conflict of
interest may exist between such Indemnified Party and the Indemnifying Party
with respect to such claim, the fees and expenses of any counsel employed by the
Indemnified Party shall be at the expense of the Indemnifying Party; provided
that, if the Indemnifying Party is obligated to pay the fees and expenses of
counsel for other Indemnified Parties, such Indemnifying Party shall be
obligated to pay only the fees and expenses associated with one attorney or law
firm for the Indemnified Parties, unless there exists a conflict of interest or
separate and different defenses among the Indemnified Parties. No Indemnifying
Party, in the defense of any such claim or litigation, shall, except with the
consent of each Indemnified Party, 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)  If the indemnification provided for in this Section 1.7 is
held by a court of competent jurisdiction to be unavailable to an Indemnified
Party with respect to any loss, claim, damage, liability or action referred to
herein, then the Indemnifying Party, in lieu of indemnifying such Indemnified
Party hereunder, shall contribute to the amounts paid or payable by such
Indemnified Party as a result of such loss, claim, damage, liability or action
in such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party on the one hand and of the Indemnified Party on the other in
connection with the statements or omissions which resulted in such loss, claim,
damage, liability or action as well as any other relevant equitable
considerations. The relative fault of the Indemnifying Party and of the
Indemnified Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Indemnifying Party or by the Indemnified Party and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. Notwithstanding the foregoing, the maximum
amount which any Holder shall be required to contribute pursuant to this Section
1.7(d) shall be limited to an amount equal to the net proceeds actually received
by such Holder from the sale of Registrable Securities effected pursuant to such
registration.

          1.8  Information by Holder. The Holders of securities included in any
registration shall furnish to the Corporation in writing such information
regarding such Holders, the Registrable Securities held by such Holders and the
distribution proposed by such Holders as the Corporation may reasonably request
in writing and as shall be required in connection with any registration,
qualification or compliance referred to in this Section 1.

          1.9  Rule 144 Reporting. With a view to making available the benefits
of certain rules and regulations of the Commission which may at any time permit
the sale of the Registrable Securities to the public without registration, the
Corporation agrees to use its best efforts to:

                                     -11-
<PAGE>

               (a)  Make and keep public information available, as those terms
are understood and defined in Rule 144, at all times after the effective date
that the Corporation becomes subject to the reporting requirements of the
Securities Act or the Exchange Act.

               (b)  Use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Corporation under the
Securities Act and the Exchange Act (at any time after it has become subject to
such reporting requirements);

               (c)  So long as a Holder owns any Registrable Securities to
furnish to the Holder forthwith upon request a written statement by the
Corporation as to its compliance with the reporting requirements of said Rule
144, and of the Securities Act and the Exchange Act, a copy of the most recent
annual or quarterly report of the Corporation, and such other reports and
documents of the Corporation and other information in the possession of or
reasonably obtainable by the Corporation as a Holder may reasonably request in
availing itself of any rule or regulation of the Commission allowing a Holder to
sell any such securities without registration. The Corporation will take action
reasonably requested by a Holder to facilitate the transfer of Registrable
Securities pursuant to Rule 144.

          1.10 Transfer of Registration Rights. Any Holder may assign its rights
hereunder to any purchaser of the Registrable Securities; provided, that
immediately after the transfer the further disposition of any of the securities
is restricted by the Securities Act; and provided further, however, that such
purchaser or transferee shall, as a condition to the effectiveness of such
assignment, be required to execute a counterpart to this Agreement agreeing to
be treated as the seller or transferor hereunder whereupon such purchaser or
transferee shall have the benefits of, and shall be subject to the restrictions
contained in, this Agreement applicable to the seller or transferor.
