         2.1 Generally. If the Company shall determine to register any of its
Common Stock for its own account or for the account of any other party, other
than a registration relating solely to employee benefit plans, or a registration
relating solely to a Rule 145 transaction, or a registration on any form of
registration statement that does not permit secondary sales, the Company will:

             [a] promptly give to the Holder written notice thereof and of the
      anticipated effective date of such registration; and

             [b] use its best efforts to include in such registration (and any
      related qualification under blue sky laws or other compliance), except as
      set forth in Section 2.2(b) hereof, and in any underwriting involved
      therein, all the Registrable Securities specified in a written request or
      requests made by the Holder and received by the Company within thirty (30)
      days after the written notice from the Company described in clause [a]
      above is mailed or otherwise delivered by the Company to the Holder in
      accordance with this Agreement. Such written request may specify any or
      part of a Holder's Registrable Securities.

         2.2 Underwriting.

             [a] If the registration of which the Company gives notice is for a
      registered public offering involving an underwriting, the Company shall so
      advise the Holder as a part of the written notice given pursuant to
      Section 2.1(a) hereof. In such event, the right of the Holder to
      registration pursuant to this Section 2 shall be conditioned upon the
      Holder's participation in such underwriting and the inclusion of the
      Holder's Registrable Securities in the underwriting to the extent provided
      herein. The Holder proposing to distribute its securities through such
      underwriting shall (together with the Company and other holders of
      securities of the Company with registration rights to participate therein
      distributing their securities through such underwriting) enter into an
      underwriting agreement in customary form with the representatives of the
      underwriter or underwriters selected by the Company, including customary
      indemnification and contribution agreements.


                                       3
<PAGE>   4

             [b] Notwithstanding any other provision of this Section 2, if the
      lead representative of the underwriters advises the Company in writing
      that marketing factors require a limitation on the number of shares to be
      underwritten, the lead representative may (subject to the limitations set
      forth below) exclude all Registrable Securities from, or limit the number
      of Registrable Securities to be included in, the registration and
      underwriting. The Company shall so advise the Holder, and the number of
      shares of securities that are entitled to be included in the registration
      and underwriting shall be allocated first to the Company for securities
      being sold for its own account and thereafter as set forth in Section 10
      hereof.

             [c] If the Holder or any other person requesting inclusion of their
      securities in a registration statement does not agree to the terms of any
      such underwriting, the Holder or such person shall be excluded therefrom
      by written notice from the Company or the lead representative of the
      underwriters. Any Registrable Securities or other securities excluded or
      withdrawn from such underwriting shall be withdrawn from such
      registration. If shares of such other person are so excluded from the
      registration, and if the number of shares of Registrable Securities to be
      included in such registration was previously reduced as a result of
      marketing factors pursuant to Section 2.2(b) hereof, then the Company
      shall offer to the Holder and to other persons who have retained rights to
      include Registrable Securities in the registration the right to include
      additional Registrable Securities in the registration in an aggregate
      amount equal to the number of shares of Registrable Securities so
      excluded, with such shares of Registrable Securities to be allocated in
      accordance with Section 10 hereof.

      3. DEMAND REGISTRATION.

         3.1 Demand for Registration.

             [a] If the Company shall receive from the Holder at any time, or
      from time to time, a written request that the Company effect any
      registration with respect to all or a part of the Registrable Securities,
      the Company will, as soon as practicable, and, in any event, within ninety
      (90) days after the Company's receipt of a written request pursuant to
      this Section 3.1, use its best efforts to effect such registration
      (including, without limitation, filing post-effective amendments,
      appropriate qualifications under applicable blue sky or other state
      securities laws, and appropriate compliance with the Securities Act and
      any other governmental requirements or regulations) as would permit or
      facilitate the sale and distribution of all or such portion of such
      Registrable Securities as are specified in such request. The Holder agrees
      that it will not request registration of less than 250,000 shares of
      Registrable Securities.

             [b] The Company shall not be obligated to effect, or to take any
      action to effect, any such registration pursuant to this Section 3.1:

                 [i] in any particular jurisdiction in which the Company would
          be required to qualify to do business or execute a general consent to
          service of process in effecting such registration, qualification, or
          compliance, unless the


                                       4
<PAGE>   5

          Company is already subject to service in such jurisdiction and except
          as may be required by the Securities Act;

                 [ii] after the Company has initiated two such registrations
          pursuant to this Section 3.1 (counting for these purposes only
          registrations which have been declared or ordered effective and
          pursuant to which Registrable Securities requested by Holders to be
          included herein have been sold); and

                 [iii] during the period starting with the date sixty (60) days
          prior to the Company's good faith estimate of the date of filing of a
          registration statement for the account of the Company and ending on a
          date ninety (90) days after the effective date thereof.

             [c] The registration statement filed pursuant to the request of the
      Holder pursuant to this Section 3 may, subject to the provisions of
      Section 3.2 and Section 10 hereof, include other securities of the Company
      with respect to which registration rights have been granted, and may
      include securities of the Company being sold for the account of the
      Company. If the Company shall request inclusion in any registration
      pursuant to this Section 3 of securities being sold for its own account,
      or if other persons shall request inclusion in any registration pursuant
      to this Section 3, the Holder shall offer to include such securities in
      the underwritten offering and may condition such offer on their acceptance
      of the further applicable provisions of this Agreement.

         3.2 Postponed Registration. Subject to clauses [i] through [iii] of
Section 3.1(b) hereof, the Company shall file a registration statement to
register the Registrable Securities requested pursuant to this Section 3 as soon
as practicable, but in any event within ninety (90) days after receipt of the
request of the Holder; provided, however, that if (i) in the good faith judgment
of the Board of Directors of the Company, such registration would be seriously
detrimental to the Company, and the Board of Directors of the Company concludes,
as a result, that it is essential to defer the filing of such registration
statement at such time, and (ii) the Company shall furnish to the Holder a
certificate signed by an executive officer of the Company stating that in the
good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company for such registration statement to be filed
in the near future and that it is, therefore, essential to defer the filing of
such registration statement, then the Company shall have the right to defer such
filing for a period of not more than ninety (90) days after receipt of the
request of the Holder; provided further, that the Company shall not defer its
obligation in this matter more than once in any 18-month period.

         3.3 Underwriting.

             [a] In connection with any underwriting effected hereunder, the
      Company shall enter into such reasonable agreements (including
      underwriting agreements) and make such representations and warranties and
      take all such other actions in connection therewith in order to expedite
      or facilitate the disposition of the Registrable Securities pursuant to
      any applicable registration statement contemplated herein as may


                                       5
<PAGE>   6

      be reasonably requested by the Holder in connection with any sale or
      resale pursuant to any applicable registration statement.

             [b] If the Holder shall request that the registration be in the
      form of a firm commitment underwritten offering, the right of any such
      Holder to registration shall be conditioned upon such Holder's
      participation in such underwriting and the inclusion of such Holder's
      Registrable Securities in the underwriting to the extent provided herein.
      In connection with a firm commitment underwritten offering demanded by the
      Holder, the Company shall, upon request of the Holder, furnish to the
      Holder and each underwriter, upon the effectiveness of the registration
      statement:

                 [i] a certificate, dated such date, signed on behalf of the
          Company by the principal executive officer of the Company, confirming,
          as of the date thereof, that any preliminary prospectus or prospectus
          that is a part of the registration statement as of their respective
          dates do not and will not at any time contain an untrue statement of a
          material fact or omit to state a material fact necessary, in light of
          the circumstances under which they were made, not misleading;

                 [ii] an opinion of counsel for the Company covering matters
          customarily set forth in an underwriting agreement for firm commitment
          underwritten offerings;

                 [iii] a comfort letter from the Company's independent
          accountants, in the customary form and covering matters of the type
          customarily covered by comfort letters to underwriters in connection
          with firm commitment underwritten offerings; and

                 [iv] such other documents and certificates as may be reasonably
          requested by the Holder or the lead representative of the underwriters
          in connection with such firm commitment underwritten offering.

             [c] The Holder may elect to include in such underwritten offering
      all or a part of the Registrable Securities the Holder holds.

             [d] In connection with an underwritten offering hereunder, the
      Company shall (together with the Holder and all other persons proposing to
      distribute their securities through such underwritten offering) enter into
      an underwriting agreement in customary form (including customary
      indemnification and contribution provisions) with the lead representative
      of the underwriter or underwriters selected for such underwriting by the
      Company, which underwriters are reasonably acceptable to the Holder.

             [e] Notwithstanding any other provision of this Section 3, if the
      lead representative of the underwriters advises the Holder in writing that
      marketing factors require a limitation on the number of shares to be
      included in such underwritten offering, the number of shares to be
      included in the underwritten offering shall be allocated first to


                                       6
<PAGE>   7

      the Holder, then to the Company for securities being sold for its own
      account, and thereafter as set forth in Section 10 hereof.

             [f] If other persons who have requested inclusion in such
      registration as provided above do not agree to the terms of any such
      underwritten offering, such person shall be excluded therefrom by written
      notice from the Company, the lead representative of the underwriters or
      the Holder. Any Registrable Securities or other securities excluded or
      withdrawn from such underwriting shall be withdrawn from such
      registration. If shares of such other person are so excluded from the
      registration, and if the number of shares of Registrable Securities to be
      included in such registration was previously reduced as a result of
      marketing factors pursuant to Section 3.3(e) hereof, then the Holder shall
      offer to the Company and to other persons who have retained rights to
      include Registrable Securities in the registration the right to include
      additional Registrable Securities in the registration in an aggregate
      amount equal to the number of shares of Registrable Securities so
      excluded, with such shares of Registrable Securities to be allocated in
      accordance with Section 10 hereof.

      4. REGISTRATION EXPENSES. All Registration Expenses incurred in connection
with any registration, qualification or compliance pursuant to Sections 2 and 3
hereof shall be borne by the Company. All Selling Expenses relating to
securities so registered shall be borne by the Company, except that in no event
shall the Company be responsible for payment of the underwriters' discount
and/or selling commissions in connection with the registration of the
Registrable Securities of the Holder.

      5. REGISTRATION PROCEDURES.

         5.1 In the case of each registration effected by the Company pursuant
to this Agreement, the Company will keep the Holder advised in writing as to the
initiation of each registration and as to the material progress and completion
thereof.

         5.2 At its expense, the Company will use its best efforts to:

             [a] keep such registration effective for a period of one hundred
      eighty (180) days or until the Holder has completed the distribution
      described in the registration statement relating thereto; provided,
      however, that such 180-day period shall be extended for a period of time
      equal to the period the Holder refrains from selling any securities
      included in such registration at the request of an underwriter of Common
      Stock (or other securities of the Company);

             [b] prepare and file with the Commission such amendments and
      supplements to such registration statement and the prospectus made a part
      of such registration statement as may be necessary to comply with the
      provisions of the Securities Act with respect to the disposition of all
      securities covered by such registration statement;

             [c] furnish such number of prospectuses and other documents
      incident thereto, including any amendment of or supplement to the
      prospectus, as the Holder from time to time may reasonably request;


                                       7
<PAGE>   8

             [d] cause all such Registrable Securities registered pursuant
      hereunto to be listed on each securities exchange, if any, on which
      similar securities issued by the Company are then listed and comply with
      all applicable blue sky laws to enable the Registrable Securities to be
      publicly offered and sold in the states in which such Registrable
      Securities will be offered;

             [e] provide a transfer agent and registrar for all Registrable
      Securities registered pursuant to such registration statement and a CUSIP
      number for all such Registrable Securities, in each case not later than
      the effective date of such registration;

             [f] advise the Holder promptly and, if requested by the Holder,
      confirm such advice in writing:

                 [i] when the prospectus or any prospectus supplement or
          post-effective amendment has been filed and, with respect to any
          applicable registration statement or any post-effective amendment
          thereto, when the same has become effective;

                 [ii] of any request by the Commission for amendments to the
          registration statement or amendments or supplements to the prospectus
          or for additional information relating thereto

                 [iii] of the issuance by the Commission of any stop order
          suspending the effectiveness of the registration statement under the
          Securities Act or of the suspension by any state securities commission
          of the qualification of the Registrable Securities for offering or
          sale in any jurisdiction or the initiation of any proceeding for any
          of the preceding purposes; or

                 [iv] of the existence of any fact or the happening of any event
          that makes any statement of a material fact made in the registration
          statement, the prospectus, any amendment or supplement thereto or any
          document incorporated by reference therein untrue, or that requires
          the making of any additions to or changes in the registration
          statement in order to make the statements therein not misleading, or
          that requires the making of any additions to or changes in the
          prospectus in order to make the statements therein, in the light of
          the circumstances under which they were made, not misleading.

          If at any time the Commission shall issue any stop order suspending
          the effectiveness of the registration statement, or any state
          securities commission or other regulatory authority shall issue an
          order suspending the qualification or exemption from qualification of
          the Registrable Securities under state securities or blue sky laws,
          the Company shall use its best efforts to obtain the withdrawal or
          lifting of such order at the earliest possible time;

             [g] furnish to the Holder, before filing with the Commission,
      copies of any registration statement or any prospectus included therein or
      any amendments or supplements to any such registration statement or
      prospectus (including all documents incorporated by reference after the
      initial filing of such registration statement), which


                                       8
<PAGE>   9

      documents will be subject to the review and comment of the Holder for a
      period of at least three (3) business days, and the Company will not file
      any such registration statement or prospectus or any amendment or
      supplement to any such registration statement or prospectus (including all
      such documents incorporated by reference) to which the Holder shall
      reasonably object within three (3) business days after the receipt
      thereof. The Holder shall be deemed to have reasonably objected to such
      filing if such registration statement, amendment, prospectus or supplement
      as applicable, as proposed to be filed, contains a material misstatement
      or omission or fails to comply with the applicable requirements of the
      Securities Act;

             [h] promptly prior to the filing of any document that is to be
      incorporated by reference into a registration statement or prospectus,
      provide copies of such document to the Holder, make the Company's
      representatives available for discussion of such document and other
      customary due diligence matters, and include such information in such
      document prior to the filing thereof as the Holder may reasonable request;

             [i] make available at reasonable times for inspection by the Holder
      and any attorney or accountant retained by the Holder, all financial and
      other records, pertinent corporate documents of the Company and cause the
      Company's officers, directors and employees to supply all information
      reasonably requested by the Holder, attorney or accountant in connection
      with such registration statement or any post-effective amendment thereto
      subsequent to the filing thereof and prior to its effectiveness;

             [j] if requested by the Holder, promptly include in any
      registration statement or prospectus, pursuant to a supplement or
      post-effective amendment if necessary, such information as the Holder may
      reasonably request to have included therein, including, without
      limitation, information relating to the "Plan of Distribution," and make
      all required filings of such prospectus supplement or post-effective
      amendment as soon as practicable after the Company is notified of the
      matters to be included in such prospectus supplement or post-effective
      amendment;

             [k] furnish to the Holder upon its reasonable request, without
      charge, at least one copy of the registration statement, as first filed
      with the Commission, and of each amendment thereto, including all
      documents incorporated by reference therein and all exhibits (including
      exhibits incorporated therein by reference);

             [l] prior to any public offering of Registrable Securities,
      cooperate with the Holder and its counsel in connection with the
      registration and qualification of the Registrable Securities under the
      securities or blue sky laws of such jurisdictions as the Holder may
      request and do any and all other acts or things reasonably necessary or
      advisable to enable the disposition in such jurisdictions of the
      Registrable Securities covered by the applicable registration statement;
      provided, however, that the Company shall not be required to register or
      qualify as a foreign corporation where it is not now so qualified or to
      take any action that would subject it to the service of process in suits
      or to taxation, other than as to matters and transactions relating to the
      registration statement, in any jurisdiction where it is not now so
      subject;


                                       9
<PAGE>   10

             [m] use its reasonable best efforts to cause the disposition of the
      Registrable Securities covered by the registration statement to be
      registered with or approved by such other governmental agencies or
      authorities as may be necessary to enable the seller or sellers thereof to
      consummate the disposition of such Registrable Securities;

             [n] comply with all applicable rules and regulations of the
      Commission, and make generally available to the Holder with regard to any
      applicable registration statement, as soon as practicable, a consolidated
      earnings statement meeting the requirements of Rule 158 under the
      Securities Act (which need not be audited) covering a 12-month period
      beginning after the effective date of the registration statement (as such
      term is defined in paragraph (c) of Rule 158 under the Securities Act);
      and

             [o] make appropriate officers of the Company available to the
      Holder for meetings with prospective purchasers of the Registrable
      Securities and prepare and present to potential investors customary "road
      show" material in a manner consistent with other new issuances of other
      securities similar to the Registrable Securities.

      6. INDEMNIFICATION.

         6.1 The Company will indemnify the Holder, its officers, directors,
employees, agents and representatives, and each underwriter, if any, and each
person who controls (within the meaning of Section 15 of the Securities Act) the
Holder or any such underwriter, against all expenses, claims, losses, damages,
and liabilities (or actions, proceedings, or settlements in respect thereof),
arising out of or based on any untrue statement (or alleged untrue statement) of
a material fact contained in any prospectus, offering circular, or other
document (including any related registration statement, notification, or the
like) incident to any such registration, qualification, or compliance, or based
on any omission (or alleged omission) to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
or any violation by the Company of the Securities Act or any applicable state
securities laws, or any rules or regulations thereunder applicable to the
Company and relating to action or inaction required of the Company in connection
with any such registration, qualification, or compliance, and will reimburse the
Holder, its officers, directors, employees, agents and representatives, and each
such underwriter, and each such person who controls the Holder and any such
underwriter, for any legal and any other expenses reasonably incurred in
connection with investigating and defending or settling any such claim, loss,
damage, liability or action, as such expenses are incurred; provided, that the
Company will not be liable in any such case to the extent that any such claim,
loss, damage, liability, or expense arises out of or is based on any untrue
statement or omission based upon written information furnished to the Company by
the Holder or underwriter and stated to be specifically for use therein. It is
agreed that the indemnity agreement contained in this Section 6.1 shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability
or action if such settlement is effected without the written consent of the
Company (which consent shall not be unreasonably withheld). The foregoing
indemnity agreement is in addition to any liability which the Company may
otherwise have to the Holder or to any such officer, director, employee, agent,
representative, underwriter or control person.


                                       10
<PAGE>   11

         6.2 The Holder will, if Registrable Securities held by the Holder are
included in the securities as to which such registration, qualification, or
compliance is being effected, indemnify the Company, its officers, directors,
employees, agents and representatives, and each underwriter, if any, of the
Company's securities covered by such a registration statement, and each person
who controls (within the meaning of Section 15 of the Securities Act) the
Company or any such underwriter, against all claims, losses, damages and
liabilities (or actions in respect thereof) arising out of or based on any
untrue statement (or alleged untrue statement) of a material fact contained in
any such registration statement, prospectus, offering circular, or other
document, or any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading and will reimburse the Company, its officers, directors, employees,
agents and representatives, and each such underwriter, and each such person who
controls the Company and any such underwriter, for any legal or any other
expenses reasonably incurred in connection with investigating or defending any
such claim, loss, damage, liability, or action, in each case to the extent, but
only to the extent, that such untrue statement (or alleged untrue statement) or
omission (or alleged omission) is made in such registration statement,
prospectus, offering circular, or other document in reliance upon and in
conformity with written information furnished to the Company by the Holder and
stated to be specifically for use therein; provided, however, that the
obligations of the Holder hereunder shall not apply to amounts paid in
settlement of any such claims, losses, damages, or liabilities (or actions in
respect thereof) if such settlement is effected without the written consent of
the Holder (which consent shall not be unreasonably withheld); provided further,
that in no event shall any indemnity obligation under this Section 6.2 exceed
the gross proceeds from the offering received by the Holder with respect to its
sale of Registrable Securities pursuant to the prospectus, less the amount of
any damages that the Holder has otherwise been required to pay by reason of such
untrue statement or alleged untrue statement or omission or alleged omission.
The foregoing indemnity agreement is in addition to any liability which the
Holder may otherwise have to the Company or any such officer, director,
employee, agent, representative, underwriter or control person.

         6.3 Promptly after receipt by an indemnified party under Section 6.1 or
6.2 hereof of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under such section, notify each party against whom indemnification is to
be sought in writing of the commencement thereof (but the failure to so notify
an indemnifying party shall not relieve the indemnifying party from any
liability which it may have under this Section 6). In case any such action is
brought against any indemnified party, and it notifies an indemnifying party of
the commencement thereof, the indemnifying party will be entitled to participate
therein, and to the extent it may elect by written notice delivered to the
indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof with counsel satisfactory to
such indemnified party. Notwithstanding the foregoing, the indemnified party or
parties shall have the right to employ its or their own counsel in any such
case, but the fees and expenses of such counsel shall be at the expense of such
indemnified party or parties unless (i) the employment of such counsel shall
have been authorized in writing by one of the indemnifying parties in connection
with the defense of such action, (ii) the indemnifying parties shall not have
employed counsel to have charge of the defense of such action within a
reasonable time after notice of commencement of the action, or (iii) such
indemnified party or parties shall have reasonably concluded that there may be
defenses available to it or them which are different from or additional to those
available


                                       11
<PAGE>   12

to one or all of the indemnifying parties (in which case the indemnifying
parties shall not have the right to direct the defense of such action on behalf
of the indemnified party or parties), in any of which events such fees and
expenses shall be borne by the indemnifying parties. Anything in this Section
6.3 to the contrary notwithstanding, an indemnifying party shall not be liable
for any settlement or any claim or action effected without its written consent;
provided, however, that such consent shall not be unreasonably withheld.

         6.4 If the indemnification provided for in this Section 6 is for any
reason unavailable to an indemnified party with respect to any loss, liability,
claim, damage, or expense referred to herein, then the indemnifying party, in
lieu of indemnifying such indemnified party hereunder, shall contribute to the
amount paid or payable by such indemnified party, as a result of such loss,
liability, claim, damage or expense, in such proportion as IS appropriate to
reflect the relative fault of the indemnifying party on the one hand and of the
indemnified party on the other in connection with the statements or omissions of
the indemnifying party and of the indemnified party. Such relative fault shall
be determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the indemnifying party or by the indemnified
party, and the parties' relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission; provided, that in
no event shall contribution by the Holder under this Section 6.4 exceed the
gross proceeds from the offering received by the Holder.

         6.5 Notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered
into in connection with the underwritten offering are in conflict with the
foregoing provisions, the provisions in the underwriting agreement shall
control.

      7. INFORMATION BY HOLDER. The Holder shall furnish to the Company such
information regarding the Holder and the distribution proposed by the Holder as
the Company may reasonably request in writing and as shall be reasonably
required in connection with any registration, qualification, or compliance
referred to in this Agreement.

      8. TRANSFER OR ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause the
Company to register securities granted to the Holder by the Company under
Section 2 hereof, or the right to demand that the Company register securities
granted under Section 3 hereof, may be transferred or assigned by the Holder
only to a transferee or assignee of not less than 10,000 shares of Registrable
Securities (as presently constituted and subject to subsequent adjustments for
stock splits, stock dividends, reverse stock splits, and the like); provided,
however, that the Company is given written notice at the time of or within a
reasonable time after said transfer or assignment, stating the name and address
of the transferee or assignee and identifying the securities with respect to
which such registration rights are being transferred or assigned; provided
further, that the transferee or assignee of such rights assumes in writing the
obligations of the Holder under this Agreement.

      9.  "MARKET STAND-OFF" AGREEMENT.

          9.1 If requested by the Company and the lead representative of the
underwriters of Common Stock (or other securities of the Company), neither the
Holder, nor any officer or director of the Company or holder of more than five
percent (5%) of the outstanding capital stock of the Company, shall sell or
otherwise transfer or dispose of any Common Stock (or other securities) of the
Company held by such person (other than those included in the registration)
during a period of up to ninety (90) days following the effective date of a
registration statement of the Company filed under the Securities Act; provided,
that such agreement shall only apply to the first such registration statement of
the Company that includes securities to be sold on its behalf to the public in
an underwritten offering.

          9.2 The obligations described in this Section 9 shall not apply to a
registration relating solely to employee benefit plans on Form S-1 or Form S-8
or similar forms that may be promulgated in the future, or a registration
relating solely to a Rule 145 transaction on Form S-4 or similar forms that may
be promulgated in the future. The Company may impose stop-transfer instructions
with respect to the shares (or securities) subject to the foregoing restriction
until the end of said 180-day period.

      10. ALLOCATION OF REGISTRATION OPPORTUNITIES. In any circumstance in which
all of the Registrable Securities and/or other shares of Common Stock with
registration rights (the "Other Shares") requested to be included in a
registration on behalf of the Holder and/or other persons cannot be so included
as a result of limitations of the aggregate number of shares of Registrable
Securities and/or Other Shares that may be so included, the number of shares of
Registrable Securities and/or Other Shares that may be so included shall be
allocated among the Holder and/or the other persons requesting inclusion of
shares pro rata on the basis of the number of shares of Registrable Securities
and/or Other Shares that would be held by the Holder and/or the other persons.
If the Holder and/or the other persons do not request inclusion of the maximum
number of shares of Registrable Securities and/or Other Shares allocated to them
pursuant to the above-described procedure, the remaining portion of this
allocation shall be reallocated among the Holder and/or the other persons whose
allocations did not satisfy their requests pro rata on the basis of the number
of shares of Registrable Securities and/or Other Shares that would be held by
the Holder and/or the other persons and this procedure shall be repeated until
all of the shares of Registrable Securities and Other Shares which may be
included in the registration on behalf of the Holder and/or the other persons
have been so allocated. The Company shall not limit the number of Registrable
Securities to be included in a registration pursuant to this Agreement in order
to include shares held by persons with no registration rights.

      11. LIMITATIONS ON REGISTRATION OF OTHER SECURITIES. From and after the
date of this Agreement, the Company shall not, without the prior written consent
of the Holder, enter into any agreement with any holder or prospective holder of
any securities of the Company giving such holder or prospective holder any
registration rights the terms of which are as or more favorable than
registration rights granted to the Holder hereunder unless the Company shall
also give such favorable rights to the Holder hereunder.

      12. REPORTING.

          12.1 The Company agrees, when required by law, to make and keep public
information available, as those terms are understood and defined in Rule 144, at
all times.

          12.2 The Company hereby represents and warrants that all reports and
other documents required to be filed by the Company with the Commission under
the Securities Act and the Exchange Act, as of the date hereof, have been filed.
The Company will use its best efforts to file with the Commission, in a timely
manner, all reports and other documents required to be filed by the Company
under the Securities Act and the Exchange Act after the date hereof.

          12.3 The Company will provide written evidence of compliance with
Section 12.1 hereof and the filing of all reports contemplated by Section 12.2
hereof to the Holder promptly upon receipt of a written request for such
evidence from the Holder.

      13. TERMINATION OF REGISTRATION RIGHTS. The right of the Holder to request
registration or inclusion in any registration pursuant to Section 2 hereof shall
terminate on the closing of the first Company initiated registered public
offering of Common Stock if all shares of Registrable Securities held or
entitled to be held upon conversion or exercise by the Holder may immediately be
sold under Rule 144 during any 90-day period, or on such date after the closing
of the first Company initiated registered public offering of Common Stock if all
shares of Registrable Securities held or entitled to be held upon conversion or
exercise by the Holder may immediately be sold under Rule 144 during any 90-day
period; provided, however, that the provisions of this Section 13 shall not
apply to the Holder if and when it owns more than five percent (5%) of the
Company's outstanding stock until such time as the Holder owns less than five
percent (5%) of the outstanding stock of the Company.

      14. TERMINATION OF PRIOR REGISTRATION RIGHTS. Any registration rights
granted to the Holder prior to the date hereof concerning any Registrable
Securities held by the Holder, whether by written agreement or otherwise, are
hereby terminated and superseded by this Agreement. This Agreement shall be
deemed to amend and restate any such prior agreements granting such registration
rights, but only to the extent of Registrable Securities held by the Holder.

      15. MISCELLANEOUS.

          15.1 Governing Law. This Agreement shall be governed in all respects
by the laws of the State of Delaware, without giving effect to the principles of
conflicts of laws thereof.

          15.2 Successors and Assigns. Except as otherwise expressly provided
herein, the provisions hereof shall inure to the benefit of, and be binding
upon, the successors, assigns, heirs, executors and administrators of the
parties hereto.

          15.3 Entire Agreement; Amendment; Waiver. This Agreement, together
with the Warrant and any Renewal Warrants provided for in connection with the
Systems Access Agreement, the First Network Services Agreement and the Second

agreement between the parties with


                                       14
<PAGE>   15

regard to the registration rights of the Holder. Neither this Agreement nor any
term hereof may be amended, waived, discharged or terminated, except with the
consent of the parties.

          15.4 Notices. All notices, requests, consents, and other
communications under this Agreement shall be in writing and shall be mailed by

         15.5 Delays or Omissions. No delay or omission to exercise any right,
power or remedy accruing to the Holder, upon any breach or default of the
Company under this Agreement shall impair any such right, power or remedy of the
Holder, nor shall it be construed to be a waiver of any such breach or default,
or an acquiescence therein, or of or in any similar breach or default thereafter
occurring; nor shall any waiver of any single breach or default be deemed a
waiver of any other breach or default theretofore or thereafter occurring. Any
waiver, permit, consent or approval of any kind or character on the part of the
Holder of any breach or default under this Agreement or any waiver on the part
of the Holder of any provisions or conditions of this Agreement must be made in

writing. All remedies, either under this Agreement or by law or otherwise
afforded to the Holder, shall be cumulative and not alternative.

         15.6 Rights; Separability. Unless otherwise expressly provided herein,
the Holder's rights hereunder are several rights, not rights jointly held with
any other person who holds securities with registration rights. In case any
provision of this Agreement shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.
