          2.1  Delivery of Stock/Consideration. The Company has delivered, and
               -------------------------------
each Holder has acquired, the Common Stock set forth on Schedule I with respect
to such Holder aggregating seventy-five thousand (75,000) shares of the Common
Stock (the "Shares") in consideration for the execution and delivery of the
Third Amendment.

     3.   REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF HOLDER.
          ----------------------------------------------------

          3.1  Investment Intention. Each Holder is acquiring the Shares solely
               --------------------
for its own account, for investment purposes, with no present intention of and
with no view toward distributing all or any part of the Shares to others for
resale or otherwise participating, directly or indirectly, in any distribution
of the Shares in violation of state or federal securities laws. Each Holder
understands that the Shares have not been registered under any state or federal
securities laws based upon the understanding of the Company that the issuance of
the Shares as described in this Agreement is exempt from such registration.
Accordingly, the Shares will be treated as Restricted Securities, as defined in
Rule 144 of the Securities Act, under the provisions of Rule 144 as promulgated
by the Commission. Each Holder agrees that the certificates representing the
Shares will contain a legend to this effect as follows:

          "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
          WITH THE SECURITIES AND EXCHANGE COMMISSION UNDER THE SECURITIES ACT
          OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY OTHER JURISDICTION.
          THE SALE OR OTHER DISPOSITION OF THESE SHARES IS PROHIBITED UNLESS
          SUCH SALE OR OTHER DISPOSITION IS IN ACCORDANCE WITH THE REGISTRATION
          REQUIREMENTS OF SUCH ACT AND THE SECURITIES LAWS OF ANY OTHER
          APPLICABLE JURISDICTION OR PURSUANT TO AN EXEMPTION FROM SUCH
          REGISTRATION REQUIREMENTS."

                                       3
<PAGE>

          The Reliance by the Company upon an exemption from registration is
predicated, in part, upon the representations and warranties of each Holder
contained in this Section 3.

          3.3    Evaluation of Investment. Each Holder has such knowledge and
                 ------------------------
experience in financial and business matters in general, and in investments in
particular, as to enable it to evaluate the merits and risks of an investment in
the Company. Each Holder has been furnished during the course of the
transactions contemplated hereby and prior to the execution of this Agreement
with all documents and information concerning the Company as requested from time
to time, has been encouraged by the Company to have the transactions reviewed by
its legal counsel or other advisor, and has had, along with its legal counsel or
other advisor, the opportunity to ask questions of the representatives of the
Company and receive satisfactory answers to it concerning the Company and has
been able to obtain any and all information concerning the Company that it has
desired.

          3.4    Restrictions on Sale of the Shares. Each Holder of the Shares
                 ----------------------------------
agrees not to effect any sale or distribution of such Shares, including a sale
pursuant to Rule 144 under the Securities Act during the ninety (90) days prior
to, and during the one hundred twenty (120) day period beginning on, the
effective date of any demand registration made pursuant to Section 2.2 of the
Registration Rights Agreement dated as of June 18, 2001, by and between the
Company and HealthPlan Holdings, Inc. (the "HealthPlan Holdings Registration
Agreement"), a copy of which has been furnished to each Holder, unless such sale
or distribution is part of any such registration.

     4.   REGISTRATION RIGHTS.
          -------------------

          4.1    Registration of Shares. As soon as practicable following the
                 ----------------------
delivery of the Shares, the Company shall file a Registration Statement with the
Commission to cover the sale of the Shares by the Holders. The Registration
Statement shall be on such form as shall then be available to the Company and
which the Company believes will be most expediently reviewed by the Commission
and achieve such registration, and may include the shares of other selling
stockholders or of the Company. The Company shall use its best efforts to
achieve the prompt effectiveness of the Registration Statement under this
Section 4.1 and to maintain it current until the Shares covered thereby have
been sold. The registration of the Shares pursuant to this Section 4.1 shall not
require any demand, written or oral, nor any other form of notification from the
Holders. Each Holder agrees that, during any day after the delivery of the
Shares, and while the Registration Statement covering the Shares is in effect,
it shall not sell more than twenty-five percent (25%) of the average daily
trading volume of the Company's common stock during the preceding ninety (90)
day period.

          4.2    Piggy-Back Registration.
                 -----------------------

          (a)    Piggy-Back Rights. If all of the Shares are not sold during the
                 -----------------
registration contemplated by Section 4.1 and at any time the Company proposes to
file a Registration Statement under the Securities Act with respect to an
offering of equity securities, or securities or other obligations exercisable or
exchangeable for, or convertible into, equity securities, by the Company for its
own account or by shareholders of the Company for their own account (or by

                                       4
<PAGE>

the Company and by shareholders of the Company), other than a Registration
Statement (i) filed in connection with any employee stock option or other
benefit plan, (ii) for an exchange offer or offering of securities solely to the
Company's existing shareholders or (iii) for a dividend reinvestment plan, then
the Company shall (x) give written notice of such proposed filing to the holders
of Shares as soon as practicable but in no event less than forty-five (45) days
before the anticipated filing date, which notice shall describe the amount and
type of securities to be included in such offering, the intended method(s) of
distribution, and the name of the proposed managing Underwriter or Underwriters,
if any, of the offering, and (y) offer to the holders of Shares in such notice
the opportunity to register such number of Shares as such holders may request in
writing within fifteen (15) days following receipt of such notice (a "Piggy-Back
Registration"). The Company shall cause such Shares to be included in such
registration and shall use its best efforts to cause the managing Underwriter or
Underwriters of a proposed underwritten offering to permit the Shares requested
to be included in a Piggy-Back Registration to be included on the same terms and
conditions as any similar securities of the Company and to permit the sale or
other disposition of such Shares in accordance with the intended method(s) of
distribution thereof.

          (b)    Reduction of Offering. If the managing Underwriter or
                 ---------------------
Underwriters for a Piggy-Back Registration that is to be an underwritten
offering advises the Company and the holders of Shares in writing that the
dollar amount or number of shares of Common Stock which the Company desires to
sell, taken together with shares of Common Stock, if any, as to which
registration has been demanded pursuant to written contractual arrangements with
persons other than the holders of Shares hereunder, the Shares as to which
registration has been requested under this Section 4.2, and the shares of Common
Stock, if any, as to which registration has been requested pursuant to the
written contractual piggy-back registration rights of other shareholders of the
Company, exceeds the maximum dollar amount or maximum number of shares that can
be sold in such offering without adversely affecting the proposed offering
price, the timing, the distribution method, or the probability of success of
such offering (such maximum dollar amount or maximum number of shares, as
applicable, the "Maximum Number of Shares"), then the Company shall include in
such registration: (i) first, the shares of Common Stock or other securities
that the Company desires to sell that can be sold without exceeding the Maximum
Number of Shares; (ii) second, if the registration is a "demand" registration
undertaken at the demand of persons other than the holders of Shares pursuant to
written contractual arrangements with such persons, then to the extent that the
Maximum Number of Shares has not been reached under the foregoing clause (i),
the shares of Common Stock for the account of demanding persons that can be sold
without exceeding the Maximum Number of Shares; (iii) third, to the extent that
the Maximum Number of Shares has not been reached under the foregoing clauses
(i) and (ii), the Shares as to which registration has been requested under this
Section 4.2; and (iv) fourth, to the extent that the Maximum Number of Shares
has not been reached under the foregoing clauses (i), (ii) and (iii), the shares
of Common Stock, if any, as to which registration has been requested pursuant to
written contractual piggy-back registration rights which such other shareholders
desire to sell that can be sold without exceeding the Maximum Number of Shares.

          (c)    Withdrawal. Any holder of Shares may elect to withdraw such
                 ----------
holder's request for inclusion of Shares in any Piggy-Back Registration by
giving written notice to the

                                       5
<PAGE>

Company of such request to withdraw prior to the effectiveness of the
Registration Statement. The Company may also elect to withdraw a registration
statement at any time prior to the effectiveness of the Registration Statement.
Notwithstanding any such withdrawal, the Company shall pay all expenses incurred
by the holders of Shares in connection with such Piggy-Back Registration as
provided in Section 5.3.

     5.   REGISTRATION PROCEDURES.
          -----------------------

          5.1    Filings; Information. Whenever the Company is required to
                 --------------------
effect the registration of any Shares pursuant to Section 4, the Company shall
use its best efforts to effect the registration and sale of such Shares in
accordance with the intended method(s) of distribution thereof as expeditiously
as practicable, and in connection with any such request:

                 (a)   Filing Registration Statement. The Company shall, as
                       -----------------------------
     expeditiously as possible, prepare and file with the Commission a
     Registration Statement on any form for which the Company then qualifies or
     which counsel for the Company shall deem appropriate and which form shall
     be available for the sale of all Shares to be registered thereunder in
     accordance with the intended method(s) of distribution thereof, and shall
     use its best efforts to cause such Registration Statement to become and
     remain effective for the requisite period; provided, however, that the
                                                --------  -------
     Company shall have the right to defer any Piggy-Back Registration for up to
     the lesser of thirty (30) days or such lesser period as may be applicable
     to deferment of any demand registration to which such Piggy-Back
     Registration relates, in each case if the Company shall furnish to the
     holders a certificate signed by the Chief Executive Officer of the Company
     stating that, in the good faith judgment of the Board of Directors of the
     Company, it would be materially detrimental to the Company and its
     shareholders for such Registration Statement to be effected at such time.

                 (b)   Copies. The Company shall, prior to filing a
                       ------
     Registration Statement or prospectus, or any amendment or supplement
     thereto, furnish without charge to the holders of Shares included in such
     registration, and such holders' legal counsel, copies of such Registration
     Statement as proposed to be filed, each amendment and supplement to such
     Registration Statement (in each case including all exhibits thereto and
     documents incorporated by reference therein), the prospectus included in
     such Registration Statement (including each preliminary prospectus), and
     such other documents as the holders of Shares included in such registration
     or legal counsel for any such holders may request in order to facilitate
     the disposition of the Shares owned by such holders.

                 (c)   Amendments and Supplements. The Company shall prepare
                       --------------------------
     and file with the Commission such amendments, including post-effective
     amendments, and supplements to each such Registration Statement and the
     prospectus used in connection therewith as may be necessary to keep such
     Registration Statement effective and in compliance with the provisions of
     the Securities Act until all Shares have been sold.

                                       6
<PAGE>

                 (d)    Notification. After the filing of a Registration
                        ------------
     Statement, the Company shall promptly, and in no event more than two (2)
     Business Days after such filing, notify the holders of Shares included in
     such Registration Statement of such filing, and shall further notify such
     holders promptly and confirm such advice in writing in all events within
     two (2) Business Days of the occurrence of any of the following: (i) when
     such Registration Statement becomes effective; (ii) when any post-effective
     amendment to such Registration Statement becomes effective; (iii) of any
     stop order issued or threatened by the Commission (and the Company shall
     take all actions required to prevent the entry of such stop order or to
     remove it if entered); and (iv) of any request by the Commission for any
     amendment or supplement to such Registration Statement or any prospectus
     relating thereto or for additional information or of the occurrence of an
     event requiring the preparation of a supplement or amendment to such
     prospectus so that, as thereafter delivered to the purchasers of the
     securities covered by such Registration Statement, such prospectus will not
     contain an 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 promptly make available to the
     holders of Shares included in such Registration Statement any such
     supplement or amendment; except that before filing with the Commission a
     Registration Statement or prospectus or any amendment or supplement
     thereto, including documents incorporated by reference, the Company shall
     furnish to the holders of the Shares included in such Registration
     Statement and to the legal counsel for any such holders, copies of all such
     documents proposed to be filed sufficiently in advance of filing to provide
     such holders and legal counsel with a reasonable opportunity to review such
     documents and comment thereon.

                 (e)    State Securities Laws Compliance. The Company shall use
                        --------------------------------
     its best efforts to (i) register or qualify the Shares covered by any
     Registration Statement under such securities or "blue sky" laws of such
     jurisdictions in the United States as the holders of the Shares included in
     such Registration Statement (in light of their intended plan of
     distribution) may request and (ii) cause such Shares covered by the
     Registration Statement to be registered with or approved by such other
     governmental authorities as may be necessary by virtue of the business and
     operations of the Company and do any and all other acts and things that may
     be necessary or advisable to enable the holders of the Shares included in
     such Registration Statement to consummate the disposition of such Shares in
     such jurisdictions; provided, however, that the Company shall not be
                         --------  -------
     required to qualify generally to do business in any jurisdiction where it
     would not otherwise be required to qualify but for this paragraph (e), or
     subject itself to taxation in any such jurisdiction.

                 (f)    Agreements for Disposition. The Company shall enter into
                        --------------------------
     customary agreements (including, if applicable, an underwriting agreement
     in customary form) and take such other actions as are reasonably required
     in order to expedite or facilitate the disposition of such Shares. The
     representations, warranties and covenants of the Company in any
     underwriting agreement which are made to or for the benefit of any
     Underwriters shall also be made to and for the benefit of the holders of
     Shares included in such registration statement. No holder of Shares
     included in such registration statement shall be required to make any
     representations or warranties in the underwriting agreement

<PAGE>

     except, if applicable, with respect to such holder's organization, good
     standing, authority, title to the Shares, lack of conflict of such sale
     with such holder's material agreements and organizational documents, and
     with respect to written information relating to such holder that such
     holder has furnished in writing expressly for inclusion in such
     Registration Statement.

     accounting officer of the Company and all other officers and members of the
     management of the Company shall cooperate fully in any offering of Shares
     hereunder, which cooperation shall include, without limitation, the
     preparation of the Registration Statement with respect to such offering and
     all other offering materials and related documents, and participation in

                 (h)    Records. The Company shall make available for inspection
                        -------
     by the holders of Registrable Securities included in such Registration
     Statement, any Underwriter participating in any disposition pursuant to

     enable them to exercise their due diligence responsibility, and cause the

     to each holder of Shares included in any Registration Statement a signed
     counterpart, addressed to such holder, of (i) any opinion of counsel to the
     Company delivered to any Underwriter and (ii) any comfort letter from the
     Company's independent public accountants delivered to any Underwriter. In
     the event no legal opinion is delivered to any Underwriter, the Company
     shall furnish to each holder of Shares included in such Registration
     Statement, at any time that such holder elects to use a prospectus, an
     opinion of counsel to the Company to the effect that the Registration
     Statement containing such prospectus has been declared effective and that
     no stop order is in effect.

                 (j)    Earnings Statement. The Company shall comply with all
                        ------------------

     and make available to its shareholders, as soon as practicable, an earnings
     statement covering a period of twelve (12) months, beginning within three
     (3) months after the effective date of the registration statement, which
     earnings statement shall satisfy the provisions of Section 11(a) of the
     Securities Act and Rule 158 thereunder.

                 (k)    Listing. The Company shall use its best efforts to cause
                        -------
     all Shares included in any registration to be listed on such exchanges or
     otherwise designated for trading in the same manner as similar securities
     issued by the Company are then listed or designated or, if no such similar
     securities are then listed or designated, in a manner

                                       8
<PAGE>

                 ----------------------------------
from the Company of the happening of any event of the kind described in Section
5.1(d)(iv), or upon any suspension by the Company, pursuant to a written insider
trading compliance program adopted by the Company's Board of Directors, of the
ability of all "insiders" covered by such program to transact in the Company's
securities because of the existence of material non-public information, each
holder of Shares included in any registration shall immediately discontinue
disposition of such Shares pursuant to the Registration Statement covering such
Shares until such holder receives the supplemented or amended prospectus
contemplated by Section 5.1(d)(iv) or the restriction on the ability of
"insiders" to transact in the Company's securities is removed, as applicable,
and, if so directed by the Company, each such holder will deliver to the Company
all copies, other than permanent file copies then in such holder's possession,
of the most recent prospectus covering such Shares at the time of receipt of

     6.   INDEMNIFICATION AND CONTRIBUTION.
          --------------------------------

          6.1  Indemnification by the Company. The Company agrees to indemnify
               ------------------------------
and hold harmless each Holder and each other holder of Shares and each of their
respective officers, employees, affiliates, directors, partners, members,
attorneys and agents, and each person, if any, who controls such Holder (within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act) (each, a "Holder Indemnified Party"), from and against any expenses,
losses, judgments, claims, damages or liabilities, whether joint or several,
arising out of or based upon any untrue statement (or alleged untrue statement)
of a material fact contained in any Registration Statement under which such
Shares were registered under the Securities Act, any preliminary prospectus,
final prospectus or summary prospectus contained in the Registration Statement,
or any amendment or supplement to such Registration Statement, or arising out of
or based upon any omission (or alleged omission) to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading, or any violation by the Company of the Securities Act or any rule or
regulation promulgated thereunder applicable to the Company and relating to
action or inaction required of the Company in connection with any such
registration; and the Company shall promptly, but in no event more than five (5)
Business Days after request for payment, pay directly or reimburse each Holder
Indemnified Party for any legal and any other expenses reasonably incurred by
such Holder Indemnified Party in connection with investigating and defending any
such expense, loss, judgment, claim, damage, liability or action; provided,
however, that the Company will not be liable in any such case to the extent that
any such expense, loss, claim, damage or liability arises out of or is based
upon any untrue statement or omission made in such Registration Statement,
preliminary prospectus, final prospectus, or summary prospectus, or any such
amendment or supplement, in reliance upon and in conformity with information
furnished to the Company, in writing, by any selling Holder and stated to be
specifically for use therein. The Company also shall indemnify any Underwriter
of the Shares, their officers, affiliates, directors, partners, members and
agents and each person who controls such Underwriter on substantially the same
basis as that of the indemnification provided above in this Section 6.1.

          6.2  Indemnification by Holders of Shares. Each selling holder of
               ------------------------------------
Shares will, in the event that any registration is being effected under the
Securities Act pursuant to this Agreement of any Shares held by such selling
holder, indemnify and hold harmless the Company, each of its directors and
officers and each underwriter (if any), and each other person, if any, who
controls such selling holder or such underwriter within the meaning of the
Securities Act, against any losses, claims, judgments, damages or liabilities,
whether joint or several, insofar as such losses, claims, judgments, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement of a material fact contained in any Registration Statement
under which such Shares were registered under the Securities Act, any
preliminary prospectus, final prospectus or summary prospectus contained in the
Registration Statement, or any amendment or supplement to the Registration
Statement, or arise out of or are based upon any omission to state a material
fact required to be stated therein or necessary to make the statement therein
not misleading, if the statement or omission was made in reliance upon and in
conformity with information furnished in writing to the Company by such selling
holder and stated to be specifically for use therein, and shall reimburse the
Company, its directors and officers, and each such controlling person for any
legal or other expenses

                                       10
<PAGE>

reasonably incurred by any of them in connection with investigating or defending
any such loss, claim, damage, liability or action. Each selling holder's
indemnification obligations hereunder shall be several and not joint and shall
be limited to the amount of any net proceeds actually received by such selling
holder.

          6.3  Conduct of Indemnification Proceedings. Promptly after receipt by
               --------------------------------------
any person of any notice of any expense, loss, judgment, claim, damage,
liability or any action in respect of which indemnity may be sought pursuant to
Section 6.1 or 6.2, such person (the "Indemnified Party") shall, if a claim in
respect thereof is to be made against any other person for indemnification
hereunder, notify such other person (the "Indemnifying Party") in writing of the
expense, loss, claim, judgment, damage, liability or action; provided, however,
                                                             --------  -------
that the failure by the Indemnified Party to notify the Indemnifying Party shall
not relieve the Indemnifying Party from any liability which the Indemnifying
Party may have to such Indemnified Party hereunder, except and solely to the
extent the Indemnifying Party is actually prejudiced by such failure. If the
Indemnified Party is seeking indemnification with respect to any claim or action
brought against the Indemnified Party, then the Indemnifying Party shall be
entitled to participate in such claim or action, and, to the extent that it
wishes, jointly with all other Indemnifying Parties, to assume the defense
thereof with counsel satisfactory to the Indemnified Party. After notice from
the Indemnifying Party to the Indemnified Party of its election to assume the
defense of such claim or action, the Indemnifying Party shall not be liable to
the Indemnified Party for any legal or other expenses subsequently incurred by
the Indemnified Party in connection with the defense thereof other than
reasonable costs of investigation; provided, however, that in any action in
                                   --------  -------
which both the Indemnified Party and the Indemnifying Party are named as
defendants, the Indemnified Party shall have the right to employ separate
counsel (but no more than one such separate counsel) to represent the
Indemnified Party and its controlling persons who may be subject to liability
arising out of any claim in respect of which indemnity may be sought by the
Indemnified Party against the Indemnifying Party, with the fees and expenses of
such counsel to be paid by such Indemnifying Party if, based upon the written
opinion of counsel of such Indemnified Party, representation of both parties by
the same counsel would be inappropriate due to actual or potential differing
interests between them. No Indemnifying Party shall, without the prior written
consent of the Indemnified Party, consent to entry of judgment or effect any
settlement of any claim or pending or threatened proceeding in respect of which
the Indemnified Party is or could have been a party and indemnity could have
been sought hereunder by such Indemnified Party, unless such judgment or
settlement includes an unconditional release of such Indemnified Party from all
liability arising out of such claim or proceeding.

          6.4  Contribution.
               ------------

               (a)  If the indemnification provided for in the foregoing
     Sections 6.1, 6.2 and 6.3 is unavailable to any Indemnified Party in
     respect of any expense, loss, judgment, claim, damage, liability or action
     referred to herein, then each such 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 expense, loss,
     judgment, claim, damage, liability or action in such proportion as is
     appropriate to reflect the relative fault of the Indemnified Parties and
     the Indemnifying Parties in connection

                                       11
<PAGE>

     with the actions or omissions which resulted in such expense, loss,
     judgment, claim, damage, liability or action, as well as any other relevant
     equitable considerations. The relative fault of any Indemnified Party and
     any Indemnifying 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 such Indemnified Party or such Indemnifying Party
     and the parties' relative intent, knowledge, access to information and
     opportunity to correct or prevent such statement or omission.

               (b)  The parties hereto agree that it would not be just and
     equitable if contribution pursuant to this Section 6.4 were determined by
     pro rata allocation or by any other method of allocation which does not
     --- ----
     take account of the equitable considerations referred to in the immediately
     preceding Section 6.4(a). The amount paid or payable by an Indemnified
     Party as a result of any expense, loss, judgment, claim, damage, liability
     or action referred to in the immediately preceding paragraph shall be
     deemed to include, subject to the limitations set forth above, any legal or
     other expenses incurred by such Indemnified Party in connection with
     investigating or defending any such action or claim. Notwithstanding the
     provisions of this Section 6.4, no holder of Shares shall be required to
     contribute any amount in excess of the dollar amount of the net proceeds
     (after payment of any underwriting fees, discounts, commissions or taxes)
     actually received by such holder from the sale of Shares which gave rise to
     such contribution obligation. 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.

     7.   MISCELLANEOUS.
          -------------

          7.1  Rule 144. The Company covenants that it shall file any reports
               --------
required to be filed by it under the Securities Act and the Exchange Act and
shall take such further action as the holders of Shares may reasonably request,
all to the extent required from time to time to enable such holders to sell
Shares without registration under the Securities Act within the limitation of
the exemptions provided by Rule 144 under the Securities Act, as such Rules may
be amended from time to time, or any similar Rule or regulation hereafter
adopted by the Commission.

          7.2  Assignment; No Third Party Beneficiaries. This Agreement and the
               ----------------------------------------
rights, duties and obligations of the Company hereunder may not be assigned or
delegated by the Company in whole or in part. This Agreement and the rights,
duties and obligations of each Holder hereunder may be not be assigned or
delegated by such Holder in whole or in part except to a person that directly,
or indirectly through one or more intermediaries, controls, or is controlled by,
or is or under common control with, such Holder. This Agreement and the
provisions hereof shall be binding upon and shall inure to the benefit of each
of the parties and their respective successors and permitted assigns. This
Agreement is not intended to confer any rights or benefits on any persons that
are not party hereto other than as expressly set forth in Article 6 and this

                                       2
<PAGE>

acquiring the Placement Shares for investment purposes, with no present
intention of and with no view toward distributing all or any part of the
Placement Shares to others for resale or otherwise participating, directly or
indirectly, in any distribution of the Placement Shares in violation of state or
federal securities laws. Purchaser understands that the Placement Shares have
not been registered under any state or federal securities laws based upon the
understanding of the Company that the issuance of the Placement Shares as
described in this Agreement is exempt from such registration. Accordingly, the
Placement Shares will be treated as Restricted Securities, as defined in Rule
144 of the Securities Act, under the provisions of Rule 144 as promulgated by
the Commission. The purchaser agrees that the Certificates representing the
Placement Shares will contain a legend to this effect as follows:

         "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
          WITH THE SECURITIES AND EXCHANGE COMMISSION UNDER THE SECURITIES ACT
          0F 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY OTHER JURISDICTION.
          THE SALE OR OTHER DISPOSITION OF THESE SHARES IS PROHIBITED UNLESS
          SUCH SALE OR OTHER DISPOSITION IS IN ACCORDANCE WITH THE REGISTRATION
          REQUIREMENTS OF SUCH ACT AND THE SECURITIES LAWS OF ANY OTHER
          APPLICABLE JURISDICTION OR PURSUANT TO AN EXEMPTION FROM SUCH
          REGISTRATION REQUIREMENTS."

          Purchaser agrees that it will not make any sale of the Placement
Shares without causing the prospectus delivery requirements of the Securities
Act to be satisfied or otherwise complying with the Securities Act and the
exemptions from registration set forth therein, and the transfer agent will be
instructed to note these restrictions on transfer on the stock records of the
Company.

          The Reliance by the Company upon an exemption from registration is
predicated, in part, upon the representations and warranties of Purchaser
contained in this Section 3.

          3.2 Authority. Purchaser is a duly and validly existing corporation in
              ---------
good standing under the laws of its state of incorporation and has the power and
authority to execute this Agreement and carry out the transactions contemplated
hereby. All corporate and other action on the part of Purchaser required to
authorize the purchase of the Placement Shares from the Company has been taken
and no consent of, authorization of or filing with any person or governmental
agency is necessary in order for Purchaser to execute this Agreement or carry
out the transactions contemplated hereby to be performed by Purchaser.

          3.3 Evaluation of Investment. Purchaser has such knowledge and
              ------------------------
experience in financial and business matters in general, and in investments in
particular, as to enable it to evaluate the merits and risks of an investment in
the Company. Purchaser has been furnished during the course of the transactions
contemplated hereby and prior to the execution of this Agreement with all
documents and information concerning the Company as requested from

                                       3
<PAGE>

time to time, has been encouraged by the Company to have the transactions
reviewed by its legal counsel or other advisor, and has had, along with its
legal counsel or other advisor, the opportunity to ask questions of the
representatives of the Company and receive satisfactory answers to it concerning
the Company and has been able to obtain any and all information concerning the
Company that it has desired.

     4.   REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF THE COMPANY
          ---------------------------------------------------------

          PVC hereby represents and warrants to the Purchaser as follows:

          4.1  Stock.  The Placement Shares have been duly authorized by the
               -----
Company, and when issued at Closing under the terms hereof will be fully paid
and non-assessable.

          4.2  Corporate Authority. The Company is a duly and validly existing
               -------------------
corporation in good standing under the laws of its state of incorporation and
has taken all corporate action necessary or required on its part to authorize
the sale of the Placement Shares to the Purchaser and no consent of,
authorization of or filing with any person or governmental agency is necessary

contemplated hereby to be performed by the Company.

     5.   REGISTRATION RIGHTS.
          -------------------

          5.1  Registration of Placement Shares. As soon as practicable
               --------------------------------
following the Closing, the Company shall file a Registration Statement with the
Commission to cover the sale of the Placement Shares by the Purchaser. The
Registration Statement shall be on such form as shall then be available to the
Company and which the Company believes will be most expediently reviewed by the
Commission and achieve such registration, and may include the shares of other
selling stockholders or of the Company. The Company shall use its best efforts
to achieve the prompt effectiveness of the Registration Statement under this
Section 5.1 and to maintain it current until the Placement Shares covered
thereby have been sold. The registration of the Placement Shares pursuant to
this Section 5.1 shall not require any demand, written or oral, nor any other
form of notification from the Purchaser and shall not count as a "Demand
Registration" for purposes of Subsection 5.2(a).

          5.2  Demand Registration.
               -------------------

               (a)  Request for Registration. At any time, if all of the
                    ------------------------
     Placement Shares are not sold during the initial registration pursuant to
     Section 5.1, the holders of a majority-in-interest of the Placement Shares
     may make a written demand for registration under the Securities Act of all
     or part of their Placement Shares (a "Demand Registration"). Any demand for
     a Demand Registration shall specify the number of Placement Shares proposed
     to be sold and the intended method(s) of distribution thereof. The Company
     will notify all holders of Placement Shares of the demand, and each holder
     of Placement Shares who wishes to include all or a portion of such holder's
     Placement Shares in the Demand Registration (each holder including
     Placement Shares in such

                                       4
<PAGE>

     registration, a "Demanding Holder") shall so notify the Company within
     fifteen (15) days after the receipt by the holder of the notice from the
     Company. Upon any such request, the Demanding Holders shall be entitled to
     have their Placement Shares included in the Demand Registration, subject to
     Section 5.2(d) and the provisos set forth in Section 6.1(a). The Company
     shall not be obligated to effect more than two (2) Demand Registrations
     under this Section 5.2(a).

               (b)   Effective Registration. A registration will not count as a
                     ----------------------
     Demand Registration until the Registration Statement filed with the
     Commission with respect to such Demand Registration has been declared
     effective and the Company has complied with all of its obligations under
     this Agreement with respect thereto; provided, however, that if, after such
                                          --------  -------
     Registration Statement has been declared effective, the offering of
     Placement Shares pursuant to a Demand Registration is interfered with by
     any stop order, injunction or other order or requirement of the Commission
     or any other governmental agency or court, the Registration Statement with
     respect to such Demand Registration will be deemed not to have been
     declared effective.

               (c)   Underwritten Offering. If a majority-in-interest of the
                     ---------------------
     Demanding Holders so elect, the offering of such Placement Shares pursuant
     to such Demand Registration shall be in the form of an underwritten
     offering. A majority-in-interest of the Demanding Holders may select one or
     more firms of investment bankers to act as the managing Underwriter or
     Underwriters in connection with such offering and may select any additional
     managers to be used in connection with such offering.

               (d)   Reduction of Offering. If the managing Underwriter or
                     ---------------------
     Underwriters for a Demand Registration that is to be an underwritten
     offering advises the Company and the Demanding Holders in writing that the
     dollar amount or number of shares of Placement Shares which the Demanding
     Holders desire to sell, taken together with all other shares of Common
     Stock or other securities which the Company desires to sell and the shares
     of Common Stock, if any, as to which registration has been requested
     pursuant to written contractual piggy-back registration rights held by
     other shareholders of the Company who desire to sell, exceeds the maximum
     dollar amount or maximum number of shares that can be sold in such offering
     without adversely affecting the proposed offering price, the timing, the
     distribution method, or the probability of success of such offering (such
     maximum dollar amount or maximum number of shares, as applicable, the
     "Maximum Number of Shares"), then the Company shall include in such
     registration: (i) first, the Placement Shares as to which Demand
     Registration has been requested by the Demanding Holders (pro rata in
                                                               --- ----
     accordance with the number of shares of Placement Shares held by each
     Demanding Holder, regardless of the number of shares of Placement Shares
     which such Demanding Holder has requested be included in such registration)
     that can be sold without exceeding the Maximum Number of Shares; (ii)
     second, to the extent that the Maximum Number of Shares has not been
     reached under the foregoing clause (i), the shares of Common Stock or other
     securities that the Company desires to sell that can be sold without
     exceeding the Maximum Number of Shares; (iii) third, to the extent that the
     Maximum Number of Shares has not been reached under the foregoing clauses
     (i) and (ii), the shares of Common Stock for the account of other

                                       5
<PAGE>

     persons that the Company is obligated to register pursuant to written
     contractual arrangements with such persons (to be allocated among the
     persons requesting inclusion in such registration pursuant to such
     contractual arrangements pro rata in accordance with the number
                              --- ----
     of shares of Common Stock with respect to which such persons have the right
     to request such inclusion under such contractual arrangements, regardless
     of the number of shares which each such person has actually requested to be
     included in such registration) and that can be sold without exceeding the
     Maximum Number of Shares; and (iv) fourth, to the extent that the Maximum
     Number of Shares have not been reached under the foregoing clauses (i),
     (ii) and (iii), the shares of Common Stock that other shareholders desire
     to sell that can be sold without exceeding the Maximum Number of Shares.

               (e)  Withdrawal. If a majority-in-interest of the Demanding
                    ----------
     Holders disapprove of the terms of any underwriting or are not entitled to
     include all of their Placement Shares in any offering, such majority-in-
     interest of the Demanding Holders may elect to withdraw from such offering
     by giving written notice to the Company and the Underwriter of their
     request to withdraw prior to the effectiveness of the Registration
     Statement filed with the Commission with respect to such Demand
     Registration. If the majority-in-interest of the Demanding Holders
     withdraws from a proposed offering relating to a Demand Registration, then
     such registration shall not count as a Demand Registration provided for in
     Section 5.2(a).

          5.3  Piggy-Back Registration.
               -----------------------

               (a)  Piggy-Back Rights. If at any time the Company proposes to
                    -----------------
     file a Registration Statement under the Securities Act with respect to an
     offering of equity securities, or securities or other obligations
     exercisable or exchangeable for, or convertible into, equity securities, by
     the Company for its own account or by shareholders of the Company for their
     own account (or by the Company and by shareholders of the Company), other
     than a Registration Statement (i) filed in connection with any employee
     stock option or other benefit plan, (ii) for an exchange offer or offering
     of securities solely to the Company's existing shareholders or (iii) for a
     dividend reinvestment plan, then the Company shall (x) give written notice
     of such proposed filing to the holders of Placement Shares as soon as
     practicable but in no event less than forty-five (45) days before the
     anticipated filing date, which notice shall describe the amount and type of
     securities to be included in such offering, the intended method(s) of
     distribution, and the name of the proposed managing Underwriter or
     Underwriters, if any, of the offering, and (y) offer to the holders of
     Placement Shares in such notice the opportunity to register such number of
     Placement Shares at such holders may request in writing within fifteen (15)
     days following receipt of such notice (a "Piggy-Back Registration"). The
     Company shall cause such Placement Shares to be included in such
     registration and shall use its best efforts to cause the managing
     Underwriter or Underwriters of a proposed underwritten offering to permit
     the Placement Shares requested to be included in a Piggy-Back Registration
     to be included on the same terms and conditions as any similar securities
     of the Company and to permit the sale or other

                                       6
<PAGE>

     disposition of such Placement Shares in accordance with the intended
     method(s) of distribution thereof.

          (b) Reduction of Offering. If the managing Underwriter or
              ---------------------
     Underwriters for a Piggy-Back Registration that is to be an underwritten
     offering advises the Company and the holders of Placement Shares in writing
     that the dollar amount or number of shares of Common Stock which the
     Company desires to sell, taken together with shares of Common Stock, if
     any, as to which registration has been demanded pursuant to written
     contractual arrangements with persons other than the holders of Placement
     Shares hereunder, the Placement Shares as to which registration has been
     requested under this Section 5.3, and the shares of Common Stock, if any,
     as to which registration has been requested pursuant to the written
     contractual piggy-back registration rights of other shareholders of the
     Company, exceeds the Maximum Number of Shares, then the Company shall
     include in such registration: (i) first, the shares of Common Stock or
     other securities that the Company desires to sell that can be sold without
     exceeding the Maximum Number of Shares; (ii) second, if the registration is
     a "demand" registration undertaken at the demand of persons other than the
     holders of Placement Shares pursuant to written contractual arrangements
     with such persons, then to the extent that the Maximum Number of Shares has
     not been reached under the foregoing clause (i), the shares of Common Stock
     for the account of demanding persons that can be sold without exceeding the
     Maximum Number of Shares; (iii) third, to the extent that the Maximum
     Number of Shares has not been reached under the foregoing clauses (i) and
     (ii), the Placement Shares as to which registration has been requested
     under this Section 5.3: and (iv) fourth, to the extent that the Maximum
     Number of Shares has not been reached under the foregoing clauses (i), (ii)
     and (iii), the shares of Common Stock if any, as to which registration has
     been requested pursuant to written contractual piggy-back registration
     rights which such other shareholders desire to sell that can be sold
     without exceeding the Maximum Number of Shares.

          (c) Withdrawal. Any holder of Placement Shares may elect to
              ----------
withdraw such holder's request for inclusion of Placement Shares in any Piggy-
Back Registrarion by giving written notice to the Company of such request to
withdraw prior to the effectiveness of the Registration Statement. The Company
may also elect to withdraw a registration statment at any time prior to the
effectiveness of the Registration Statement. Notwithstanding any such
withdrawal, the Company shall pay all expenses incurred by the holders of
Placement Shares in connection with such Piggy-Back Registrarion as provided in
Section 6.3.

          5.4 Registrations on Form S-3. The holders of Placement Shares may at
              -------------------------
any time request in writing that the Company register the resale of any or all
of Registrable Securities on Form S-3 (or any similar short-form registration
which may be available at such time). Upon receipt of such written request, the
Company will promptly give written notice of the proposed registration to all
other holders of Placement Shares, and, as soon as practicable thereafter,
effect the registration of all or such portion of such holder's or holders'
Placement Shares as are specified in such request, together with all or such
portion of the Placement Shares of any other holder or holders joining in such
request as are specified in a written request given within fifteen (15) days
after receipt of such written notice from the Company; provided, however, that

          5.5 Restrictions on Arbitrage. The Purchaser agrees that it will not
              -------------------------
hedge, short, or otherwise arbitrage the Placement Shares in any manner which
would violate the registration requirements applicable as to such Placement
Shares under the Securities Act.

     6.   REGISTRATION PROCEDURES.
          -----------------------

          6.1 Filings; Information. Whenever the Company is required to effect
              --------------------
the registration of any Placement Shares pursuant to Section 5, the Company
shall use its best efforts to effect the registration and sale of such Placement
Shares in accordance with the intended method(s) of distribution thereof as
expeditiously as practicable, and in connection with any such request:

              (a) Filing Registration Statement. The Company shall, as
                  -----------------------------
expeditiously as possible and in any event within sixty (60) days after receipt
of a request for a Demand Registration pursuant to Section 5.2, prepare and file
with the Commission a Registration Statement on any form for which the Company
then qualifies or which counsel for the Company shall deem appropriate and which
form shall be available for the sale of all Placement Shares to be registered
thereunder in accordance with the intended method(s) of distribution thereof,
and shall use its best efforts to cause such Registration Statement to become
and remain effective for the requisite period; provided, however, that the
                                               -----------------
Company shall have the right to defer any Demand Registration for up to thirty
(30) days, and any Piggy-Back Registration for up to the lesser of thirty (30)
days or such lesser period as may be applicable to deferment of any demand
registration to which such Piggy-Back Registration relates, in each case if the
Company shall furnish to the holders a certificate signed by the Chief Executive
Officer of the Company stating that, in the good faith judgment of the Board of
Directors of the Company, it would be materially detrimental to the Company and
its shareholders for such Registration Statement to be effected at such time;
provided further, however, that the Company shall not have the right to exercise
-------- -------  -------
the right set forth in the immediately preceding proviso more than once in any
365-day period in respect of a Demand Registration hereunder.

          (b) Copies. The Company shall, prior to filing a Registration
              ------
Statement or prospectus, or any amendment or supplement thereto, furnish without
charge to the holders of Placement Shares included in such registration, and
such holders' legal counsel, copies of such Registration Statement as proposed
to be filed, each amendment and supplement to such Registration Statement (in
each case including all exhibits thereto and documents incorporated by reference
     ----
therein), the prospectus included in such Registration Statement (including each
preliminary prospectus), and such other documnents as the holders of Placement
Shares included in such registration or

                                       8
<PAGE>

legal counsel for any such holders may request in order to facilitate the
disposition of the Placement Shares owned by such holders.

          (c) Amendments and Supplements. The Company shall prepare and file
              --------------------------
with the Commission such amendments, including post-effective amendments, and
supplements to each such Registration Statement and the prospectus used in
connection therewith as may be necessary to keep such Registration Statement
effective and in compliance with the provisions of the Securities Act until all
Placement Shares have been sold.

          (d) Notification. After the filing of a Registration Statement, the
              ------------
Company shall promptly, and in no event more than two (2) Business Days after
such filing, notify the holders of Placement Shares included in such
Registration Statement of such filing, and shall further notify such holders
promptly and confirm such advice in writing in all events within two (2)
Business Days of the occurrence of any of the following: (i) when such
Registration Statement becomes effective; (ii) when any post-effective amendment
to such Registration Statement becomes effective; (iii) of any stop order issued
or threatened by the Commission (and the Company shall take all actions required
to prevent the entry of such stop order or to remove it if entered); and (iv) of
any request by the Commission for any amendment or supplement to such
Registration Statement or any prospectus relating thereto or for additional
information or of the occurrence of an event requiring the preparation of a
supplement or amendment to such prospectus so that, as thereafter delivered to
the purchasers of the securities covered by such Registration Statement, such
prospectus will not contain an 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 promptly make available to the holders of
Placement Shares included in such Registration Statement any such supplement or
amendment; except that before filing with the Commission a Registration
Statement or prospectus or any amendment or supplement thereto, including
documents incorporated by reference, the Company shall furnish to the holders of
the Placement Shares included in such Registration Statement and to the legal
counsel for any such holders, copies of all such documents proposed to be filed
sufficiently in advance of filing to provide such holders and legal counsel with
a reasonable opportunity to review such documents and comment thereon.

          (e) State Securities Laws Compliance. The Company shall use its best
              --------------------------------
efforts to (i) register or qualify the Placement Shares covered by any
Registration Statement under such securities or "blue sky" laws of such
jurisdictions in the United States as the holders of the Placement Shares
included in such Registration Statement (in light of their intended plan of
distribution) may request and (ii) cause such Placement Shares covered by the
Registration Statement to be registered with or approved by such other
governmental authorities as may be necessary by virtue of the business and
operations of the Company and do any and all other acts and things that may be
necessary or advisable to enable the holders of the Placement Shares included in
such Registration Statement to consummate the disposition of such Placement
Shares in such jurisdictions; provided, however, that the Company shall not be
                              --------  -------
required to qualify generally to do

                                       9
<PAGE>

     business in any jurisdiction where if would not otherwise be required to
     qualify but for this paragraph (e), or subject itself to taxation in any
     such jurisdiction.

                    (f) Agreements for Disposition. The Company shall enter into
                        --------------------------
     customary agreements (including, if applicable, an underwriting agreement
     in customary form) and take such other actions as are reasonably required
     in order to expedite or facilitate the disposition of such Placement
     Shares. The representations, warranties and covenants of the Company in any
     underwriting agreement which are made to or for the benefit of any
     Underwriters shall also be made to and for the benefit of the holders of
     Placement Shares included in such registration statement. No holder of
     Placement Shares included in such registration statement shall be required
     to make any representations or warranties in the underwriting agreement
     except, if applicable, with respect to such holder's organization, good
     standing, authority, title to the Placement Shares, lack of conflict of
     such sale with such holder's material agreements and organizational
     documents, and with respect to written information relating to such holder
     that such holder has furnished in writing expressly for inclusion in such
     Registration Statement.

                    (g) Cooperation. The principal executive officer of the
                        -----------
     Company, the principal financial officer of the Company, the principal
     accounting officer of the Company and all other officers and members of the
     management of the Company shall cooperate fully in any offering of
     Placement Shares hereunder, which cooperation shall include, without
     limitation, the preparation of the Registration Statement with respect to
     such offering and all other offering materials and related documents, and
     participation in meetings with Underwriters, attorneys, accountants and
     potential investors.

                    (h) Records. The Company shall make available for
                        -------
     inspection by the holders of Registrable Securities included in such
     Registration Statement, any Underwriter participating in any disposition
     pursuant to such registration statement and any attorney, accountant or
     other professional retained by any holder of Placement Shares included in
     such Registration Statement or any Underwriter, all financial and other
     records, pertinent corporate documents and properties of the Company, as
     shall be necessary to enable them to exercise their due diligence
     responsibility, and cause the Company's officers, directors and employees
     to supply all information requested by any of them in connection with such
     Registration Statement.

                    (i) Opinions and Comfort Letters. The Company shall furnish
                        ----------------------------
     to each holder of Placement Shares included in any Registration Statement a
     signed counterpart, addressed to such holder, of (i) any opinion of counsel
     to the Company delivered to any Underwriter and (ii) any comfort letter
     from the Company's independent public accountants delivered to any
     Underwriter. In the event no legal opinion is delivered to any Underwriter,
     the Company shall furnish to each holder of Placement Shares included in
     such Registration Statement, at any time that such holder elects to use a
     prospectus, an opinion of counsel to the Company to the effect that the
     Registration Statement containing such prospectus has been declared
     effective and that no stop order is in effect.

                                       10
<PAGE>

                    (j) Earnings Statement. The Company shall comply with all
                        ------------------
     applicable rules and regulations of the Commission and the Securities Act,
     and make available to its shareholders, as soon as practicable, an earnings
     statement covering a period of twelve (12) months, beginning within three
     (3) months after the effective date of the registration statement, which
     earnings statement shall satisfy the provisions of Section 11(a) of the
     Securities Act and Rule 158 thereunder.

                    (K) Listing. The Company shall use its best efforts to cause
                        -------
     all Placement Shares included in any registration to be listed on such
     exchanges or otherwise designated for trading in the same manner as similar
     securities issued by the Company are then listed or designated or, if no
     such similar securities are then listed or designated, in a manner
     satisfactory to the holders of a majority of the Placement Shares or
     Registrable Securities included in such registration.

               6.2 Obligation to Suspend Distribution. Upon receipt of any
                   ----------------------------------
notice from the Company of the happening of any event of the kind described in
Section 6.1(d)(iv), or in the case of a resale registration on Form S-3 pursuant
to Section 5.4 hereof, upon any suspension by the Company, pursuant to a written
insider trading compliance program adopted by the Company's Board of Directors,
of the ability of all "insiders" covered by such program to transact in the
Company's securities because of the existence of material non-public
information, each holder of Placement Shares included in any registration shall
immediately discontinue disposition of such Placement Shares pursuant to the
Registration Statement covering such Placement Shares until such holder receives
the supplemented or amended prospectus contemplated by Section 6.1(d)(iv) or the
restriction on the ability of "insiders" to transact in the Company's securities
is removed, as applicable, and, if so directed by the Company, each such holder
will deliver to the Company all copies, other than permanent file copies then in
such holder's possession, of the most recent prospectus covering such Placement
Shares at the time of receipt of such notice.

               6.3 Registration Expenses. The Company shall bear all costs
                   ---------------------
and expenses incurred in connection with any registration pursuant to Section
5.1(a), any Demand Registration pursuant to Section 5.2, and any Piggy-Back
Registration pursuant to Section 5.3, and any registration on Form S-3 effected
pursuant to Section 5.4, and all expenses incurred in performing or complying
with its other obligations under this Agreement, whether or not the Registration

and filing fees; (ii) fees and expenses of compliance with securities or "blue
sky" laws (including fees and disbursements of counsel in connection with blue
sky qualifications of the Placement Shares); (iii) printing expenses; (iv) the
Company's internal expenses (including, without limitation, all salaries and
expenses of its officers and employees); (v) the fees and expenses incurred in
connection with the listing of the Purchased as required by Section 6.1(k); (vi)
National Association of Securities Dealers, Inc. fees; (vii) fees and

pursuant to Section 6.1(i)); (viii) the fees and expenses of any special experts
retained by the Company in connection with such registration; (ix) the purchase
of selling stockholder errors and omissions insurance for the benefit of the
Purchaser in any amount equivalent to the gross proceeds to be received by the
Purchaser in connection with any

                                       11
<PAGE>

registration under this Agreement, on terms and conditions satisfactory to the
Purchaser, and (x) all fees and expenses incurred by the holders of Placement
Shares in connection with their participation in such registration, including,
without limitation, the fees and expenses of one legal counsel selected by the
holders of a majority-in-interest of the Placement Shares included in such
registration, as well as accountants and other experts selected by the
Purchaser. The Company shall have no obligation to pay any underwriting
discounts or selling commissions attributable to the Placement Shares being sold
by the holders thereof, which underwriting discounts or selling commissions
shall be borne by such holders. The Company will keep any registration effective
for at least ninety (90) days.

               6.4 Information. The holders of Placement Shares shall provide
                   -----------
such information as may reasonably be requested by the Company in connection
with the preparation of any Registration Statement, including amendments and
supplements thereto, in order to effect the registration of any Placement Shares
under the Securities Act pursuant to Section 2.

          7.   INDEMNIFICATION AND CONTRIBUTION.
               --------------------------------

               7.1 Indemnification by the Company. The Company agrees to
                   ------------------------------
indemnify and hold harmless the Purchaser and each other holder of Placement
Shares and each of their respective officers, employees, affiliates, directors,
partners, members, attorneys and agents, and each person, if any, who controls
the Purchaser (within the meaning of Section 15 of the Securities Act or Section
20 of the Exchange Act) (each, a "Purchaser Indemnified Party"), from and
against any expenses, losses, judgments, claims, damages or liabilities, whether
joint or several, arising out of or based upon any untrue statement (or alleged
untrue statement) of a material fact contained in any Registration Statement
under which such Placement Shares were registered under the Securities Act, any
preliminary prospectus, final prospectus or summary prospectus contained in the
Registration Statement, or any amendment or supplement to such Registration
Statement, or arising out of or based upon any omission (or alleged omission) to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading, or any violation by the Company of the
Securities Act or any rule or regulation promulgated thereunder applicable to
the Company and relating to action or inaction required of the Company in
connection with any such registration; and the Company shall promptly, but in no
event more than five (5) Business Days after request for payment, pay directly
or reimburse each Purchaser Indemnified Party for any legal and any other
expenses reasonably incurred by such Purchaser Indemnified Party in connection
with investigating and defending any such expense, loss, judgment, claim,
damage, liability or action; provided, however, that the Company will not be
                             --------  -------
liable in any such case to the extent that any such expense, loss, claim, damage
or liability arises out of or is based upon any untrue statement or omission
made in such Registration Statement, preliminary prospectus, final prospectus,
or summary prospectus, or any such amendment or supplement, in reliance upon and
in conformity with information furnished to the Company, in writing, by such
selling Holder and stated to be specifically for use therein. The Company also
shall indemnify any Underwriter of the Placement Shares, their officers,
affiliates, directors, partners, members and agents and each person who controls
such Underwriter on substantially the same basis as that of the indemnification
provided above in this Section 4.1.

                                       12
<PAGE>

                    7.2 Indemnification by Holders of Placement Shares. Each
                        ----------------------------------------------
selling holder of Placement Shares will, in the event that any registration is
being effected under the Securities Act pursuant to this Agreement of any
Placement Shares held by such selling holder, indemnify and hold harmless the
Company, each of its directors and officers and each underwriter (if any), and
each other person, if any, who controls such selling holder or such underwriter
within the meaning of the Securities Act, against any losses, claims, judgments,
damages or liabilities, whether joint or several, insofar as such losses,
claims, judgments, damages or liabilities (or actions in respect thereof) arise
out of or are based upon any untrue statement of a material fact contained in
any Registration Statement under which such Placement Shares were registered
under the Securities Act, any preliminary prospectus, final prospectus or
summary prospectus contained in the Registration Statement, or any amendment or
supplement to the Registration Statement, or arise out of or are based upon any
omission to state a material fact required to be stated therein or necessary to
make the statement therein not misleading, if the statement or omission was made
in reliance upon and in conformity with information furnished in writing to the
Company by such selling holder and stated to be specifically for use therein,
and shall reimburse the Company, its directors and officers, and each such
controlling person for any legal or other expenses reasonably incurred by any of
them in connection with investigating or defending any such loss, claim, damage,
liability or action. Each selling holder's indemnification obligations hereunder
shall be several and not joint and shall be limited to the amount of any net
proceeds actually received by such selling holder.

                   7.3  Conduct of Indemnification Proceedings.  Promptly after
                        --------------------------------------
receipt by any person of any notice of any expense, loss, judgment, claim,
damage, liability or any action in respect of which indemnity may be sought
pursuant to Section 7.1 or 7.2, such person (the "Indemnified Party") shall, if
a claim in respect thereof is to be made against any other person for
indemnification hereunder, notify such other person (the "Indemnifying Party")
in writing of the expense, loss, claim, judgment, damage, liability or action;
provided, however, that the failure by the Indemnified Party to notify the
--------  -------
Indemnifying Party shall not relieve the Indemnifying Party from any liability
which the Indemnifying Party may have to such Indemnified Party hereunder,
except and solely to the extent the Indemnifying Party is actually prejudiced by
such failure. If the Indemnified Party is seeking indemnification with respect
to any claim or action brought against the Indemnified Party, then the
Indemnifying Party shall be entitled to participate in such claim or action,
and, to the extent that it wishes, jointly with all other Indemnifying Parties,
to assume the defense thereof with counsel satisfactory to the Indemnified
Party. After notice from the Indemnifying Party to the Indemnified Party of its
election to assume the defense of such claim or action, the Indemnifying Party
shall not be liable to the Indemnified Party for any legal or other expenses
subsequently incurred by the Indemnified Party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that in
                                                      --------  -------
any action in which both the Indemnified Party and the Indemnifying Party are
named as defendants, the Indemnified Party shall have the right to employ
separate counsel (but no more than one such separate counsel) to represent the
Indemnified Party and its controlling persons who may be subject to liability
arising out of any claim in respect of which indemnity may be sought by the
Indemnified Party against the Indemnifying Party, with the fees and expenses of
such counsel to be paid by such Indemnifying Party if, based upon the written
opinion of counsel of such Indemnified Party, representation of both parties by
the same counsel would be inappropriate due to actual or potential differing
interests between them. No Indemnifying Party shall, without the

                                      13
<PAGE>

prior written consent of the Indemnified Party, consent to entry of judgment or
effect any settlement of any claim or pending or threatened proceeding in
respect of which the Indemnified Party is or could have been a party and
indemnity could have been sought hereunder by such Indemnified Party, unless
such judgment or settlement includes an unconditional release of such
Indemnified Party from all liability arising out of such claim or proceeding.

          7.4   Contribution.
                ------------

                     (a)   If the indemnification provided for in the foregoing
     Section 7.1, 7.2 and 7.3 is unavailable to any Indemnified Party in respect
     of any expense, loss, judgment, claim, damage, liability or action referred
     to herein, then each such 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 expense, loss, judgment, claim,
     damage, liability or action in such proportion as is appropriate to reflect
     the relative fault of the Indemnified Parties and the Indemnifying Parties
     in connection with the actions or omissions which resulted in such expense,
     loss, judgment, claim, damage, liability or action, as well as any other
     relevant equitable considerations. The relative fault of any Indemnified
     Party and any Indemnifying 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 such Indemnified Party or such Indemnifying
     Party and the parties' relative intent, knowledge, access to information
     and opportunity to correct or prevent such statement or omission.

                     (b) The parties hereto agree that it would not be just and
     equitable if contribution pursuant to this Section 7.4 were determined by
     pro rata allocation or by any other method of allocation which does not
     --- ----
     take account of the equitable considerations referred to in the immediately
     preceding Section 7.4(a). The amount paid or payable by an Indemnified
     Party as a result of any expense, loss, judgment, claim, damage, liability
     or action referred to in the immediately preceding paragraph shall be
     deemed to include, subject to the limitations set forth above, any legal or
     other expenses incurred by such Indemnified Party in connection with
     investigating or defending any such action or claim. Notwithstanding the
     provisions of this Section 7.4, no holder of Placement Shares shall be
     required to contribute any amount in excess of the dollar amount of the net
     proceeds (after payment of any underwriting fees, discounts, commissions or
     taxes) actually received by such holder from the sale of Placement Shares
     which gave rise to such contribution obligation. 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.

     8.   MISCELLANEOUS.

              --------

request, all to the extent required from time to time to enable such holders to
sell Placement Shares without registration under the Securities Act

                                      14
