    Section 3. DEMAND REGISTRATION.

              (a) REQUESTS FOR REGISTRATION. At any time after the Company shall
have effected an Initial Public Offering, the holders of not less than (x)
twenty-five (25) percent of the outstanding Registrable Securities together as a
group, or (y) a majority of the Registrable Securities held by the Designated
Investors as a group, which Registrable Securities were acquired on or after the
date hereof,


                                        4

<PAGE>


shall have the right by written notice delivered to the Company (the "Demand
Notice"), to require the Company to register (a "Demand Registration") under and
in accordance with the provisions of the Securities Act the number of
Registrable Securities requested to be so registered pursuant to the terms of
this Agreement.

         Until such time as the Company shall become eligible to use Form S-3
for the registration under the Securities Act of any of its securities, the
number of Demand Registrations pursuant to this Section 3(a) shall not exceed
two (2) for all of the holders of the Registrable Securities (the "Initial
Demand Registration"). Thereafter, one (1) Demand Registration shall become
available each year in addition to the Initial Demand Registrations provided for
in the preceding sentence (the "Additional Demand Registration") either of which
must be approved by the holders of the Registrable Securities in the same manner
specified in clause (x) or (y) in the preceding paragraph, provided, HOWEVER,
that no Demand Notice may be given with respect to such Additional Demand
Registrations prior to six months after the effective date of the immediately
preceding Demand Registration; and PROVIDED FURTHER, that no Demand Registration
shall be deemed to have occurred for purposes of this Section 3(a) if a
requested Demand Registration does not become effective or is not maintained
effective for the period required pursuant to this Section 3(a), or the amount
of Registrable Securities to be registered on behalf of the holders requesting
such Demand Registration is reduced by more than 50% pursuant to Section 3(b)
hereof, in which case the holders of Registrable Securities shall be entitled to
an additional Demand Registration in lieu thereof until such Demand Registration
is declared and maintained effective for such period.

         Within ten (10) days after receipt by the Company of a Demand Notice,
the Company shall give written notice (the "Notice") of such Demand Notice to
all other holders of Registrable Securities and shall, subject to the provisions
of Section 3(b) hereof, include in such registration all Registrable Securities
with respect to which the Company received written requests for inclusion
therein within ten (10) days after such notice is given by the Company to such
holders.

         All requests made pursuant to this Section 3 will specify the amount of
Registrable Securities to be registered and the intended methods of disposition
thereof.

         The Company shall be required to maintain the effectiveness of the
Registration Statement with respect to any Demand Registration for the lesser of



                                        5

<PAGE>

(i) 90 days after the effective date thereof and (ii) consummation of the
distribution by the holders of the Registrable Securities included in such
Registration Statement.

         Notwithstanding the foregoing paragraph, if holders of a majority of
the then outstanding Registrable Securities requested to be included in such
registration pursuant to Section 3(a) request that such Demand Registration be
a "shelf" registration pursuant to Rule 415 under the Securities Act, and the
Company is then eligible to make such a filing, the Company shall file such
Demand Registration under Rule 415 and shall keep the Registration Statement
filed in respect thereof effective for a period which shall terminate on the
earlier of (i) 180 days from the date on which the SEC declares such
Registration Statement effective and (ii) the date on which all Registrable
Securities covered by such Registration Statement have been sold pursuant to
such Registration Statement.

              (b) PRIORITY ON DEMAND REGISTRATION. If any of the Registrable
Securities registered pursuant to a Demand Registration are to be sold in a firm
commitment underwritten offering, and the managing underwriter or underwriters
advise the holders of such securities in writing that in its opinion the total
number or dollar amount of Registrable Securities proposed to be sold in such
offering is such as to materially and adversely affect the success of such
offering, then there shall be included in such firm commitment underwritten
offering the number or dollar amount of Registrable Securities that in the
opinion of such managing underwriter can be sold, and such Registrable
Securities shall be allocated PRO RATA among the holders of Registrable
Securities on the basis of the number or dollar amount of securities owned by
each such holder participating in such offering.

              (c) POSTPONEMENT OF DEMAND REGISTRATION. The Company shall be
entitled to postpone, for a reasonable period of time not in excess of ninety
(90) days, the filing of a Registration Statement if the Company determines, in
the good faith exercise of its reasonable business judgment, that such
registration and offering could adversely affect or interfere with BONA FIDE
financing plans of the Company or would require disclosure of information, the
premature disclosure of which could adversely affect the Company or any
transaction under consideration by the Company.

    Section 4. PIGGYBACK REGISTRATION.

              (a) RIGHT TO PIGGYBACK. If the Company proposes to file a
registration statement under the Securities Act with respect to an offering of




                                        6

<PAGE>


Common Stock (other than a registration statement (i) on Form S-4, Form S-8 or
any successor forms thereto or (ii) filed solely in connection with an exchange
offer or any employee benefit or dividend reinvestment plan), whether or not for
its own account, then the Company shall give written notice of such proposed
filing to the holders of Registrable Securities at least fifteen (15) days
before the anticipated filing date (the "Piggyback Notice"). The Piggyback
Notice shall offer such holders the opportunity to register in such registration
statement such amount of Registrable Securities as each such holder may request
(a "Piggyback Registration"). Subject to Section 5(b) hereof, the Company shall
include in each such Piggyback Registration all Registrable Securities with
respect to which the Company has received written requests for inclusion therein
within ten (10) days after notice has been given to the applicable holder. The
holders of Registrable Securities shall be permitted to withdraw all or part of
the Registrable Securities from a Piggyback Registration at any time prior to
the effective date of such Piggyback Registration. The Company shall not be
required to maintain the effectiveness of the Registration Statement beyond the
earlier to occur of (i) 180 days after the effective date thereof and (ii)
consummation of the distribution by the holders of the Registrable Securities
included in such Registration Statement.

              (b) PRIORITY ON PIGGYBACK REGISTRATIONS. The Company shall cause
the managing underwriter or underwriters of a proposed underwritten offering to
permit holders of Registrable Securities requested to be included in the
registration for such offering to include all such Registrable Securities on the
same terms and conditions as any other shares of Common Stock, if any, of the
Company included therein. Notwithstanding the foregoing, if the managing
underwriter or underwriters of such underwritten offering have informed the
Company in writing that it is their opinion that the total amount of securities
that such holders, the Company and any other Persons having rights to
participate in such registration, intend to include in such offering is such as
to materially and adversely affect the success of such offering, then the amount
of securities to be offered (i) for the account of holders of Registrable
Securities and (ii) for the account of all such other Persons (other than the
Company) shall be reduced or limited PRO RATA in proportion to the respective
dollar amounts of securities to be registered to the extent necessary to reduce
the total amount of securities to be included in such offering to the amount
recommended by such managing underwriter or underwriters.

    Section 5. HOLD-BACK AGREEMENTS.

              (a) RESTRICTIONS ON PUBLIC SALE BY HOLDERS OF REGISTRABLE
SECURITIES. Each holder of Registrable Securities agrees, in connection with the
Initial Public Offering and in connection with any underwritten registration of
Registrable Securities filed pursuant to Section 3 or Section 4 hereof, if
requested (pursuant to a timely written notice) by the Company or the managing
underwriter or underwriters in an underwritten offering, not to effect any
public sale or distribution of any of the Company's securities (except as part
of such underwritten offering), including a sale pursuant to Rule 144, during
the 90-day period after the closing date of each underwritten offering made by
the Company or pursuant to such Registration Statement.

         The foregoing provisions shall not apply to any holder of Registrable
Securities if such holder is prevented by applicable statute or regulation from
entering into any such agreement; PROVIDED, HOWEVER, that any such holder shall
undertake in its request to participate in any such underwritten offering, not
to effect any public sale or distribution of the class of securities covered by
such Registration Statement (except as part of such underwritten offering)
during such period unless it has provided forty-five (45) days' prior written
notice of such sale or distribution to the managing underwriter or underwriters.

              (b) RESTRICTIONS ON PUBLIC SALE BY THE COMPANY. The Company agrees
that without the written consent of the managing underwriter or underwriters in
an underwritten offering of Registrable Securities covered by a Registration
Statement filed pursuant to Section 3 or Section 4 hereof, it will not effect
any public or private sale or distribution of its equity securities, including a
sale pursuant to Regulation D under the Securities Act, during the 90-day period
beginning on the closing date of each underwritten offering made pursuant to
such Registration Statement (except (w) as part of such underwritten
registration, (x) pursuant to registrations on Form S-4 or Form S-8 or any
successor form to such forms or pursuant to any unregistered offering to the
Company's employees or directors, or to employees of its subsidiaries, pursuant
to any employee benefit plan (as defined in Rule 405 under the Securities Act),
(y) in connection with an exchange offer or (z) in connection with the
acquisition of assets by the Company or its subsidiaries).

method or methods of disposition thereof, and pursuant thereto the Company shall
as expeditiously as possible:

              (a) Prepare and file with the SEC, as soon as practicable, a

therein by reference), the Company shall furnish or otherwise make available to
the holders of the Registrable Securities covered by such Registration
Statement, their counsel and the managing underwriters, if any, copies of all
such documents proposed to be filed, which documents will be subject to the
review of such holders, their counsel and such underwriters, if any, PROVIDED,
HOWEVER, that the Company shall not be required to deliver to such holders a
copy of any such document that has not been materially changed from a copy of
such document that was previously delivered to such holders. The Company shall
not file any such Registration Statement or Prospectus or any amendments or
supplements thereto (including such documents that, upon filing, would be
incorporated or deemed to be incorporated by reference therein) to which the
holders of a majority of the Registrable Securities covered by such Registration
Statement, their counsel, or the managing underwriters, if any, shall reasonably
object, in writing, on a timely basis, unless, in the opinion of the Company,
such filing is necessary to comply with applicable law.

              (b) Prepare and file with the SEC such amendments and
post-effective amendments to each Registration Statement as may be necessary to
keep such Registration Statement continuously effective during the period

respect to a Registration Statement or any post-effective amendment, when the
same has become effective, (ii) of any request by the SEC or any other Federal
or state governmental authority for amendments or supplements to a Registration
Statement or related Prospectus or for additional information (provided, that
the Company shall not be required to notify the holders or their counsel of all

such comment letters or the Company's responses thereto to the holders or their
counsel unless such letters request information from or about the holders),
(iii) of the issuance by the SEC of any stop order suspending the effectiveness
of a Registration Statement or the initiation of any proceedings for that
purpose, (iv) if at any time the representations and warranties of the Company
contained in any agreement (including any underwriting agreement) contemplated
by Section 6(n) below cease to be true and correct, (v) of the receipt by the
Company of any notification with respect to the suspension of the qualification
or exemption from qualification of any of the Registrable Securities for sale in
any jurisdiction, or the initiation or threatening of any proceeding for such
purpose, and (vi) of the happening of any event that makes any statement made
in such Registration Statement or related Prospectus or any document
incorporated or deemed to be incorporated therein by reference untrue in any
material respect or that requires the making of any changes in such Registration
Statement, Prospectus or documents so that, in the case of the Registration
Statement, it will not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein, not misleading, and that in the case of the Prospectus,
it will not contain any untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading.

              (d) Use its best efforts to obtain the withdrawal of any order
suspending the effectiveness of a Registration Statement, or the lifting of any
suspension of the qualification (or exemption from qualification) of any of the
Registrable Securities for sale in any jurisdiction.

holders of a majority of the holders of the then outstanding Registrable
Securities being sold in connection with an underwritten offering, promptly
include in a

managing underwriters, if any, and such holders may reasonably request in

make all required filings of such Prospectus supplement or such
post-effective amendment as soon as practicable after the Company has
received such request; PROVIDED, HOWEVER, that the Company shall not be

opinion of counsel for the Company, in compliance with applicable law.

              (f) Furnish to each selling holder of Registrable Securities, its
counsel and each managing underwriter, if any, without charge, at least one
conformed copy of the Registration Statement and each post-effective amendment

its counsel, and the underwriters, if any, without charge, as many copies of the
Prospectus or Prospectuses (including each form of prospectus) and each
amendment or supplement thereto as such Persons may reasonably request in
connection with the distribution of the Registrable Securities; and the Company,
subject to the last paragraph of this Section 6, hereby consents to the use of
such Prospectus and each amendment or supplement thereto by each of the selling
holders of Registrable Securities and the underwriters, if any, in connection
with the offering and sale of the Registrable Securities covered by such
Prospectus and any such amendment or supplement thereto.

              (h) Prior to any public offering of Registrable Securities, to use

Registrable Securities, the underwriters, if any, and their respective counsel
in connection with the registration or qualification (or exemption from such
registration or qualification) of such Registrable Securities for offer and sale
under the securities or "Blue Sky" laws of such jurisdictions within the United
States as any seller or underwriter reasonably requests in writing and to keep
each such registration or qualification (or exemption therefrom) effective
during the period such Registration Statement is required to be kept effective;
PROVIDED, HOWEVER, that the Company will not be required to (A) qualify
generally to do business in any jurisdiction where it is not then so qualified
or (B) take any action that would subject it to general service of process or to
taxation in any such jurisdiction where it is not then so subject.

              (i) Cooperate with the selling holders of Registrable Securities
and the managing underwriters, if any, to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be sold, which
certificates shall be in a form eligible for deposit with The Depository Trust
Company, and enable such Registrable Securities to be in such denominations and
registered in such names as the managing underwriters, if any, or holders may
request at least two (2) business days prior to any sale of Registrable
Securities in a firm commitment public offering, but in any other such sale,
within ten (10) business days prior to having to issue the securities.

              (j) Cause the Registrable Securities covered by the Registration
Statement to be registered with or approved by such other governmental agencies
or authorities within the United States, except as may be required solely as a
consequence of the nature of such selling holder's business, in which case the
Company will cooperate in all best respects with the filing of such Registration
Statement and the granting of such approvals, as may be necessary to enable the
seller or sellers thereof or the underwriters, if any, to consummate the
disposition of such Registrable Securities.

              (k) Upon the occurrence of any event contemplated by Section
6(c)(vi) above, prepare a supplement or post-effective amendment to the
Registration Statement or a supplement to the related Prospectus or any document
incorporated or deemed to be incorporated therein by reference, or file any
other required document so that, as thereafter delivered to the purchasers of
the Registrable Securities being sold thereunder, such Prospectus will 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, in
light of the circumstances under which they were made, not misleading.

              (l) Prior to the effective date of the Registration Statement
relating to the Registrable Securities, provide a CUSIP number for the
Registrable Securities.

              (m) Use its best efforts to cause all shares of Registrable

on the Nasdaq National Market or listed on a national securities exchange if
shares of the particular class of Registrable Securities are at that time quoted
on the Nasdaq National Market or listed on such exchange, as the case may be.

agreement in form, scope and substance as is customary in underwritten
offerings) and take all such other actions reasonably requested by the holders
of a majority of the Registrable Securities being sold in connection therewith
(including those reasonably requested by the managing underwriters, if any) to
expedite or facilitate the disposition of such Registrable Securities, and in
such connection, whether or not an underwriting agreement is entered into and
whether or not the registration is an underwritten registration, (i) make such
representations and warranties to the holders of such Registrable Securities and
the underwriters, if any, with respect to the business of the Company and its
subsidiaries, and the Registration Statement, Prospectus and documents, if any,

form, substance and scope as are customarily made by issuers to underwriters in
underwritten offerings, and, if true, confirm the same if and when requested,

included in the Registration Statement), addressed to each selling holder of
Registrable Securities (unless such accountants shall be prohibited from so
addressing such letters by applicable standards of the accounting profession)
and each of the underwriters, if any, such letters to be in customary form and
covering matters of the type customarily covered in "cold comfort" letters in
connection with underwritten offerings, (iv) if an underwriting agreement is
entered into, the same shall contain indemnification provisions and procedures
substantially to the effect set forth in Section 8 hereof with respect to all
parties to be indemnified pursuant to said Section and (v) deliver such
documents and certificates as may be reasonably requested by the holders of a
majority of the Registrable Securities being sold, their counsel and the
managing underwriters, if any, to evidence the continued validity of the
representations and warranties made pursuant to Section 6(n)(i) above and to
evidence compliance with any customary conditions contained in the underwriting
agreement or other agreement entered into



                                       13

by the Company. The above shall be done at each closing under such underwriting
or similar agreement, or as and to the extent required thereunder.

              (o) Make available for inspection by a representative of the
selling holders of Registrable Securities, any underwriter participating in any
such disposition of Registrable Securities, if any, and any attorneys or
accountants retained by such selling holders or underwriter, at the offices
where normally kept, during reasonable business hours, all financial and other
records, pertinent corporate documents and properties of the Company and its
subsidiaries, and cause the officers, directors and employees of the Company and
its subsidiaries to supply all information in each case reasonably requested by
any such representative, underwriter, attorney or accountant in connection with
such Registration Statement; PROVIDED, HOWEVER, that any information that is
designated by the Company in writing as confidential at the time of delivery of
such information shall be kept confidential by such Persons unless (i)
disclosure of such information is required by court or administrative order,
(ii) disclosure of such information, in the opinion of counsel to such Person,
is required by law, or (iii) such information becomes generally available to the
public other than as a result of a disclosure or failure to safeguard by such
Person. Without limiting the foregoing, no such information shall be used by
such Person as the basis for any market transactions in securities of the
Company or its subsidiaries in violation of law.

              (p) Comply with all applicable rules and regulations of the SEC
and make generally available to its securityholders earning statements
satisfying the provisions of Section 11(a) of the Securities Act and Rule 158
thereunder, or any similar rule promulgated under the Securities Act, no later
than forty-five (45) days after the end of any twelve (12) month period (or
ninety (90) days after the end of any twelve (12) month period if such period is
a fiscal year) (i) commencing at the end of any fiscal quarter in which
Registrable Securities are sold to underwriters in a firm commitment or best
efforts underwritten offering and (ii) if not sold to underwriters in such an
offering, commencing on the first day of the first fiscal quarter of the Company
after the effective date of a Registration Statement, which statements shall
cover one of said twelve (12) month periods.

         The Company may require each seller of Registrable Securities as to
which any registration is being effected to furnish to the Company such
information regarding such seller and the distribution of such Registrable
Securities as the Company may, from time to time, reasonably request in writing
and the Company may exclude from such registration the Registrable Securities of
any seller who



                                       14
<PAGE>

unreasonably fails to furnish such information within a reasonable time after
receiving such request.

         Each holder of Registrable Securities agrees by acquisition of such
Registrable Securities that, upon receipt of any notice from the Company of the
happening of any event of the kind described in Section 6(c)(ii), 6(c)(iii),
6(c)(v) or 6(c)(vi) hereof, such holder will forthwith discontinue disposition
of such Registrable Securities covered by such Registration Statement or
Prospectus until such holder's receipt of the copies of the supplemented or
amended Prospectus contemplated by Section 6(k) hereof, or until it is advised
in writing by the Company that the use of the applicable Prospectus may be
resumed, and has received copies of any additional or supplemental filings that
are incorporated or deemed to be incorporated by reference in such Prospectus.

Inc.

    Section 8. INDEMNIFICATION.

              (a) INDEMNIFICATION BY THE COMPANY. The Company shall, without
limitation as to time, indemnify and hold harmless, to the fullest extent
permitted by law, each holder of Registrable Securities whose Registrable
Securities are covered by a Registration Statement or Prospectus, the officers,
directors and agents and employees of each of them, each Person who controls
each such holder (within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act) and the officers, directors, agents and
employees of each such controlling person, to the fullest extent lawful, from
and against any and all losses, claims, damages, liabilities, costs (including,
without limitation, costs of preparation and reasonable attorneys' fees) and
expenses (collectively, "Losses"), as incurred, arising out of or based upon any
untrue or alleged untrue statement of a material fact contained in such
Registration Statement or Prospectus or in any amendment or supplement thereto
or in any preliminary prospectus, or arising out of or based upon any omission
or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as the
same are based upon information furnished in writing to the Company by such
holder expressly for use therein.

              (b) INDEMNIFICATION BY HOLDER OF REGISTRABLE SECURITIES. In
connection with any Registration Statement in which a holder of Registrable
Securities is participating, such holder of Registrable Securities shall furnish
to the Company in writing such information as the Company reasonably requests
for use in



                                       16
<PAGE>

connection with any Registration Statement or Prospectus and agrees to
indemnify, to the fullest extent permitted by law, the Company, its
directors, officers, agents and employees, each Person who controls the
Company (within the meaning of Section 15 of the Securities Act and Section
20 of the Exchange Act), and the directors, officers, agents or employees of
such controlling persons, from and against all Losses arising out of or based
upon any untrue or alleged untrue statement of a material fact contained in
any Registration Statement or Prospectus or any amendment or supplement
thereto, or any preliminary prospectus, or arising out of or based upon any
omission or alleged omission of a material fact required to be stated therein
or necessary to make the statements therein not misleading, to the extent,
but only to the extent, that such untrue or alleged untrue statement or
omission or alleged omission is contained in any information so furnished in
writing by such holder to the Company expressly for use in such Registration
Statement or Prospectus and that such information was relied upon by the
Company in preparation of such Registration Statement or Prospectus or
amendment, supplement or preliminary prospectus; PROVIDED, HOWEVER, that the
liability of each selling holder of Registrable Securities hereunder shall be
limited to the proportion of any such loss, claim, damage, liability or
expense which is equal to the proportion that the public offering price of
the shares sold by such selling holder under such Registration Statement
bears to the total public offering price of all securities sold thereunder,
but not in any event to exceed the net proceeds received by such selling
holder from the sale of Registrable Securities covered by such Registration
Statement.

              (c) CONDUCT OF INDEMNIFICATION PROCEEDINGS. If any Person shall be
entitled to indemnity hereunder (an "indemnified party"), such indemnified party
shall give prompt notice to the party from which such indemnity is sought (the
"indemnifying party") of any claim or of the commencement of any Proceeding with
respect to which such indemnified party seeks indemnification or contribution
pursuant hereto; PROVIDED, HOWEVER, that the delay or failure to so notify the
indemnifying party shall not relieve the indemnifying party from any obligation
or liability except to the extent that the indemnifying party has been
prejudiced materially by such delay or failure. The indemnifying party shall
have the right, exercisable by giving written notice to an indemnified party
promptly after the receipt of written notice from such indemnified party of such
claim or Proceeding, to assume, at the indemnifying party's expense, the defense
of any such claim or Proceeding, with counsel reasonably satisfactory to such
indemnified party; PROVIDED, HOWEVER, that an indemnified party shall have the
right to employ separate counsel in any such claim or Proceeding and to
participate in the defense thereof, but the fees and expenses of such counsel
shall be at the expense of such indemnified



                                       17
<PAGE>

party unless: (l) the indemnifying party agrees to pay such fees and expenses;
or (2) the indemnifying party fails promptly to assume the defense of such claim
or Proceeding or fails to employ counsel reasonably satisfactory to such
indemnified party; in which case the indemnified party shall have the right to
employ counsel and to assume the defense of such claim or proceeding; PROVIDED,
HOWEVER, that the indemnifying party shall not, in connection with any one such
claim or Proceeding or separate but substantially similar or related claims or
Proceedings in the same jurisdiction, arising out of the same general
allegations or circumstances, be liable for the fees and expenses of more than
one firm of attorneys (together with appropriate local counsel) at any time for
all of the indemnified parties, or for fees and expenses that are not
reasonable. Whether or not such defense is assumed by the indemnifying party,
such indemnified party will not be subject to any liability for any settlement
made without its consent (but such consent will not be unreasonably withheld).
The indemnifying party shall not consent to entry of any judgment or enter into
any settlement that does not include as an unconditional term thereof the giving
by the claimant or plaintiff to such indemnified party of a release, in form and
substance reasonably satisfactory to the indemnified party, from all liability
in respect of such claim or litigation for which such indemnified party would be
entitled to indemnification hereunder.

              (d) CONTRIBUTION. If the indemnification provided for in this
Section 8 is unavailable to an indemnified party in respect of any Losses (other
than in accordance with its terms) or is insufficient to hold such indemnified
party harmless, then each applicable indemnifying party, in lieu of indemnifying
such indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such Losses, in such proportion as is
appropriate to reflect the relative fault of the indemnifying party, on the one
hand, and such indemnified party, on the other hand, in connection with the
actions, statements or omissions that resulted in such Losses as well as any
other relevant equitable considerations. The relative fault of such indemnifying
party, on the one hand, and indemnified party, on the other hand, shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission to state a material fact, has been taken by, or relates to
information supplied by, such indemnifying party or indemnified party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent any such action, statement or omission. The amount paid or
payable by a party as a result of any Losses shall be deemed to include any
legal or other fees or expenses incurred by such party in connection with any
investigation or Proceeding.



                                       18
<PAGE>

         The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 8(d) were determined by PRO RATA
allocation or by any other method of allocation that does not take account of
the equitable considerations referred to in the immediately preceding
paragraph. Notwithstanding the provision of this Section 8(d), an indemnifying
party that is a selling holder of Registrable Securities shall not be required
to contribute any amount in excess of the amount by which the total price at
which the Registrable Securities sold by such indemnifying party exceeds the
amount of any damages that such indemnifying party has otherwise been required
to pay by reason of such untrue or alleged untrue statement or omission or
alleged omission. 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.

    Section 9. RULE 144.

         The Company shall file the reports required to be filed by it under the
Securities Act and the Exchange Act, and will take such further action as any
holder of Registrable Securities may reasonably request, all to the extent
required from time to time to enable such holder to sell Registrable Securities
without registration under the Securities Act within the limitations of the
exemption provided by Rule 144. Upon the request of any holder of Registrable
Securities, the Company shall deliver to such holder a written statement as to
whether it has complied with such requirements.

    Section 10. UNDERWRITTEN REGISTRATIONS.

         If any Demand Registration is an underwritten offering, the holders of
a majority of the Registrable Securities covered by such Demand Registration
shall have the right to select the investment banker or investment bankers and
managers to administer the offering, subject to approval by the Company, not to
be unreasonably withheld. The Company shall have the right to select the
investment banker or investment bankers and managers to administer any Piggyback
Registration.

         No Person may participate in any underwritten registration hereunder
unless such Person (a) agrees to sell such Person's Registrable Securities on
the basis provided in any underwriting arrangements approved by the Company and
(b) completes and executes all questionnaires, powers of attorney, indemnities,




                                       19
<PAGE>

underwriting agreements and other documents required under the terms of such
underwriting arrangements.

    Section 11. MISCELLANEOUS.

              (a) AMENDMENTS AND WAIVERS. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the Company has obtained the written consent of holders
of at least a majority of the then outstanding Registrable Securities; PROVIDED
that, for so long as Wand owns at least a majority of the then outstanding
Registrable Securities, the Company must obtain the written consent of holders
of at least 67% of the then outstanding Registrable Securities. Notwithstanding
the foregoing, a waiver or consent to depart from the provisions hereof with
respect to a matter that relates exclusively to the rights of holders of
Registrable Securities whose securities are being sold pursuant to a
Registration Statement and that does not directly or indirectly affect the
rights of other holders of Registrable Securities may be given by holders of at
least a majority of the Registrable Securities being sold by such holders
pursuant to such Registration Statement; PROVIDED, that in the event Wand then
owns at least a majority of (x) the then outstanding Registrable Securities and
(y) the Registrable Securities being sold by such holders pursuant to such
Registration Statement, then such waiver or consent may be given by the holders
of at least 67% of the Registrable Securities being sold by such holders, and
PROVIDED, FURTHER, that the provisions of this sentence may not be amended,
modified, or supplemented except in accordance with the provisions of the
immediately preceding sentence.

assignment, subsequent holders of Registrable Securities.

              (e) HEADINGS. The section and paragraph headings contained in this
Agreement are for reference purposes only and shall not affect in any way the
meaning or interpretation of this Agreement.

effect to the choice of law principles thereof).

              (g) SEVERABILITY. If any term, provision, covenant or restriction
of this Agreement is held by a court of competent jurisdiction to be invalid,
illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their best efforts to find and employ an alternative means to

may be hereafter declared invalid, illegal, void or unenforceable.

              (h) ENTIRE AGREEMENT. This Agreement is intended by the parties as
a final expression of their agreement, and is intended to be a complete and
exclusive statement of the agreement and understanding of the parties hereto in

              (i) SECURITIES HELD BY THE COMPANY OR ITS AFFILIATES. Whenever the
consent or approval of holders of a specified percentage of Registrable
Securities is required hereunder, Registrable Securities held by the Company or
its affiliates (as such term is defined in Rule 405 under the Securities Act)
(other than the Stockholders or subsequent holders of Registrable Securities if
such subsequent holders are deemed to be such affiliates solely by reason of
their holdings of such Registrable Securities) shall not be counted in
determining whether such consent or approval was given by the holders of such
required percentage.
