hardware with which it interacts.

Shares) by, or enforcement against, such Purchaser of this Agreement and each of
the other Transaction Documents to which it is a party or the transactions
contemplated hereby and thereby.

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

have been, duly executed and delivered by such Purchaser and this Agreement

constitute, the legal, valid and binding obligations of such Purchaser,
enforceable against it in accordance with its terms, except as enforceability
may be limited by applicable bankruptcy, insolvency, reorganization, fraudulent
conveyance or transfer, moratorium or similar laws affecting the enforcement of
creditors' rights generally or by equitable principles relating to
enforceability (regardless of whether considered in a proceeding at law or in
equity).

     4.5  Purchase for Own Account.  The Purchased Shares and the Warrants to
          ------------------------
be acquired by such Purchaser pursuant to this Agreement are being or will be
acquired for its own account and with no intention of distributing or reselling
such Purchased Shares or Warrants or any part thereof in any transaction that
would be in violation of the securities laws of the United States of America, or
any state, without prejudice, however, to the rights of such Purchaser at all
times to sell or otherwise dispose of all or any part of such Purchased Shares
or Warrants under an effective registration statement under the Securities Act,
or under an exemption from such registration available under the Securities Act,
and subject, nevertheless, to the disposition of such Purchaser's property being
at all times within its control.  If such Purchaser should in the future decide
to dispose of any of such Purchased Shares, such Purchaser understands and
agrees that it may do so only in compliance with the Securities Act and
applicable state securities laws, as then in effect.

     4.6  Legends.  Such Purchaser agrees to the imprinting, so long as
          -------
required by law, of a legend on certificates representing all of its Purchased
Shares and shares of Common Stock issuable upon conversion of its Purchased
Shares and Warrant Shares to the following effect:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR THE SECURITIES
     LAWS OF ANY STATE.  THE SECURITIES MAY NOT BE TRANSFERRED EXCEPT PURSUANT
     TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT AND APPLICABLE STATE
     SECURITIES LAWS OR PURSUANT TO AN APPLICABLE EXEMPTION FROM THE
     REGISTRATION REQUIREMENTS OF SUCH ACT AND SUCH LAWS.

conversion thereof and any Warrant Shares at the time of issuance may not be,
registered under the Securities Act on the ground that the sale provided for in
this Agreement and the issuance of securities hereunder is exempt from
registration under the Securities Act pursuant to section 4(2) thereof, and that
the Company's reliance on such exemption is based in part on the Purchaser
representations set forth herein.

     4.8  Broker's, Finder's or Similar Fees.  There are no brokerage
          ----------------------------------
commissions, finder's fees or similar fees or commissions payable by such
Purchaser in connection with the transactions contemplated hereby based on any

                                   ARTICLE VI

                                INDEMNIFICATION
                                ---------------

     6.1  Indemnification.  Except as otherwise provided in this Article VII,
          ---------------
the Company (the "Indemnifying Party") agrees to indemnify, defend and hold
harmless each of the Purchasers and its Affiliates and their respective
officers, directors, agents, employees, subsidiaries, partners, members,
attorneys, accountants, and controlling persons (each, an "Indemnified Party")
to the fullest extent permitted by law from and against any and all losses,
Claims, or written threats thereof (including any Claim by a third party),
damages, expenses (including reasonable fees, disbursements and other charges of
counsel incurred by the Indemnified Party in any action between the Indemnifying
Party and the Indemnified Party or between the Indemnified Party and any third
party or otherwise) or other liabilities (collectively, "Losses") resulting from
or arising out of any breach of any representation or warranty, covenant or
agreement by the Company in this Agreement or the other Transaction Documents;
provided however, that if and to the extent that such indemnification is
-------- -------
unenforceable for any reason, the Indemnifying Party shall make the maximum
contribution to the payment and satisfaction of such Losses which shall be
permissible under applicable laws.  The amount of any payment to any Indemnified
Party herewith in respect of any Loss shall be of sufficient amount to make such
Indemnified Party whole for any diminution in value of the securities purchased
hereunder below the Purchase Price hereof.  In connection with the obligation of
the Indemnifying Party to indemnify for expenses as set forth above, the
Indemnifying Party shall, upon presentation of appropriate invoices containing
reasonable detail, reimburse each Indemnified Party for all such expenses

<PAGE>

                                                                              23

(including reasonable fees, disbursements and other charges of counsel incurred
by the Indemnified Party in any action between the Indemnifying Party and the
Indemnified Party or between the Indemnified Party and any third party) as they
are incurred by such Indemnified Party; provided, however, that if an
                                        --------  -------
Indemnified Party is reimbursed under this Article VII for any expenses, such
reimbursement of expenses shall be refunded to the extent it is finally
judicially determined that the Losses in question resulted primarily from the
willful misconduct or gross negligence of such Indemnified Party.

     6.2  Notification.  Each Indemnified Party under this Article VII shall,
          ------------
promptly after the receipt of notice of the commencement of any Claim against
such Indemnified Party in respect of which indemnity may be sought from the
Indemnifying Party under this Article VII, notify the Indemnifying Party in
writing of the commencement thereof. The omission of any Indemnified Party to so
notify the Indemnifying Party of any such action shall not relieve the
Indemnifying Party from any liability which it may have to such Indemnified
Party (a) other than pursuant to this Article VII or (b) under this Article VII
unless, and only to the extent that, such omission results in the Indemnifying
Party's forfeiture of substantive rights or defenses. In case any such Claim
shall be brought against any Indemnified Party, and it shall notify the
Indemnifying Party of the commencement thereof, the Indemnifying Party shall be
entitled to assume the defense thereof at its own expense, with counsel
satisfactory to such Indemnified Party in its reasonable judgment; provided,
                                                                   --------
however, that any Indemnified Party may, at its own expense, retain separate
-------
counsel to participate in such defense at its own expense. Notwithstanding the
foregoing, in any Claim in which both the Indemnifying Party, on the one hand,
and an Indemnified Party, on the other hand, are, or are reasonably likely to
become, a party, such Indemnified Party shall have the right to employ separate
counsel and to control its own defense of such Claim if, in the reasonable
opinion of counsel to such Indemnified Party, either (x) one or more defenses
are available to the Indemnified Party that are not available to the
Indemnifying Party or (y) a conflict or potential conflict exists between the
Indemnifying Party, on the one hand, and such Indemnified Party, on the other
hand, that would make such separate representation advisable; provided, however,
                                                              --------  -------
that the Indemnifying Party (i) shall not be liable for the fees and expenses of
more than one counsel to all Indemnified Parties in any one legal action or
group of related legal actions and (ii) shall reimburse the Indemnified Parties
for all of such fees and expenses of such counsel incurred in any action between
the Indemnifying Party and the Indemnified Parties or between the Indemnified
Parties and any third party, as such expenses are incurred. The Indemnifying
Party agrees that it will not, without the prior written consent of the
Purchasers, settle, compromise or consent to the entry of any judgment in any
pending or threatened Claim relating to the matters contemplated hereby (if any
Indemnified Party is a party thereto or has been actually threatened to be made
a party thereto) unless such settlement, compromise or consent includes an
unconditional release of each Indemnified Party from all liability arising or
that may arise out of such Claim. The Indemnifying Party shall not be liable for
any settlement of any Claim effected against an Indemnified Party without its
written consent, which consent shall not be unreasonably withheld.

The rights accorded to an Indemnified Party hereunder shall be in addition to
any rights that any Indemnified Party may have at common law, by separate
agreement or otherwise; provided, however, that notwithstanding the foregoing or
                        --------  -------
anything to the contrary contained in this Agreement, nothing in this Article
VII shall restrict or limit any rights that any Indemnified Party may have to
seek equitable relief.

     6.3  Contribution.  If the indemnification provided for in this Article
          ------------
VII from the Indemnifying Party is unavailable to an Indemnified Party hereunder
in respect of any Losses referred to herein, then the Indemnifying Party, in
lieu of indemnifying such Indemnified Party, shall contribute to the amount paid
or payable by such Indemnified Party as a result of such Losses in such
proportion as is appropriate to reflect the relative fault of the Indemnifying
Party and Indemnified Party in connection with the actions which resulted in
such Losses, as well as any other relevant equitable considerations.  The
relative faults of such Indemnifying Party and Indemnified Party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission to state a material fact, has been made by, or relates to
information supplied by, such Indemnifying Party or Indemnified Party, and the
parties relative intent, knowledge, access to information and opportunity to
correct or prevent such action. The amount paid or payable by a party as a
result of the Losses referred to above shall be deemed to include, subject to
the limitations set forth in Sections 6.1 and 6.2, any legal or other fees,
charges or expenses reasonably incurred by such party in connection with any
investigation or proceeding.

                                  ARTICLE VII

                      AFFIRMATIVE COVENANTS OF THE COMPANY
                      ------------------------------------

     The Company hereby covenants and agrees with the Purchasers as follows:

(with the

                                                                              25

required majority or supermajority), including any and all approvals required by
the applicable policies, rules or regulations of the NASDAQ, (i) to increase the
registered capital of the Company which will be required upon the conversion of
all authorized shares of the Series A Preferred Stock and the exercise of the
Warrants and (ii) to approve the conversion by each of the Purchasers of their
shares of Series B Preferred Stock into shares of Series A Preferred Stock in
accordance with the terms and conditions set forth in the Series B Certificate
of Designations (collectively, the "Approvals"). The Company agrees to use its
reasonable best efforts to obtain such votes as may be required for the
Approvals, including recommending to the stockholders to vote in favor of the
Approvals and voting all shares for which the Company holds proxies (unless
otherwise directed by the stockholders submitting such proxy), or is otherwise
entitled to vote, in favor of the Approvals. The Company shall bear all expenses
in connection with the holding of such meeting, including the costs and expenses
of the preparation, filing and distribution of the proxy statement.

     7.3  Reservation of Common Stock.  Upon, and subject to, obtaining the
          ---------------------------
approval relating to the increase of authorized capital as set forth in Section
7.2, the Company shall at all times reserve and keep available out of its
authorized shares of Common Stock, (i) solely for the purpose of issue or
delivery upon conversion of the Series A Preferred Stock, as provided in the
Series A Certificate of Designations, the maximum number of shares of Common
Stock that may be issuable or deliverable upon such conversion and (ii) the
maximum number of Warrant Shares that may be issuable provided, however, that,
if such approval is not obtained, the Company shall reserve the maximum number
of Common Stock shares that are authorized and not otherwise reserved for as of
the date hereof for such purpose.  Such shares of Common Stock and Warrant
Shares shall, upon such approval, be duly authorized and, when issued or
delivered in accordance with the Certificate of Designations or the Warrants, as
applicable, shall be validly issued, fully paid and non-assessable.  The Company
shall issue such shares of Common Stock and Warrant Shares, in accordance with
the terms of the Certificate of Designations or the Warrants, as applicable, and
otherwise comply with the terms hereof and thereof.

     7.4  Most Favored Nation Clause.  If the Company issues additional shares
          --------------------------
of convertible preferred stock and/or warrants (or similar securities) within
180 days following the date of this Agreement and, in connection with such
issuance, grants to any Person rights or terms that are in any manner more
favorable to the holder(s) of such  securities than the rights or terms granted
to the Purchasers under this Agreement, the Certificate of Designations, the
Warrants or the other Transaction Documents, then the applicable documentation
shall, at the option of each Purchaser, be amended promptly to provide such
Purchaser (or any permitted transferees of such Purchaser) with any of such more
favorable terms as such Purchaser (or such transferees) elect to include
therein, except that the following terms shall not be subject to amendment
pursuant to this Section 7.4: (i) the initial conversion price of the Preferred
Stock, if such amendment would stem solely from a change in the Market Price of
the Company's Common Stock due to the fact that the issuance took place on a
later date,

<PAGE>

                                                                              26

(ii) the initial exercise price of the Warrants, if such amendment would stem
solely from a change in the Market Price of the Company's Common Stock due to
the fact that the issuance took place on a later date, (iii) the mandatory
redemption date of the Preferred Stock, and (iv) the expiration date of the
Warrants.

     7.5  Books and Records.  The Company shall keep proper books of record
          -----------------
and account, in which full and correct entries shall be made of all financial
transactions and the assets and business of the Company in accordance with GAAP
consistently applied.

     7.6  Inspection.  The Company shall permit representatives of the
          ----------
Purchasers to visit and inspect any of its properties, to examine its corporate,
financial and operating records and make copies thereof or abstracts therefrom,
and to discuss its affairs, finances and accounts with their respective
directors, officers and independent public accountants, all at such reasonable
times during normal business hours and as often as may be reasonably requested
upon reasonable advance notice to the Company; provided, however, that no such
                                               --------  -------
inspection, examination or inquiry, the failure to conduct same, nor any
knowledge of any Purchaser, including any knowledge obtained by such Purchaser
in connection with any such inspection, investigation or inquiry, shall
constitute a waiver of any rights Purchaser may have under any representation,
warranty, covenant, term or agreement under any of the Transaction Documents.

                                  ARTICLE VIII

                    AFFIRMATIVE COVENANTS OF THE PURCHASERS

other Purchasers and the Company that such Purchaser will vote any shares of

voting such shares pursuant to any state or federal securities laws or the
NASDAQ rules and regulations).

Statement may be effected in the form of a firm commitment underwritten
offering; provided that the Company shall not be obligated to cooperate with the
Designated Holders hereunder in connection with more than three such
underwritten offerings or in connection with any underwritten offering where the
aggregate offering price is less than $2 million (calculated based upon the
average of the Market Price of the Common Stock on three trading days prior to
the date on which request for the underwritten offering is presented to the
Company). The Company shall use its best efforts to cause such underwritten
offering to occur and the managing underwriter or underwriters selected for such
offering shall be the Approved Underwriter selected in accordance with Section
3(g). In connection with any underwritten offering, the Company shall not be
required to include any Registrable Securities in such underwritten offering
unless the Designated Holders thereof accept the terms of the underwritten
offering as agreed upon by the Company, the Approved Underwriter and the
Underwriting Initiating Holders, and then only in such quantity as such
underwriter believes will not jeopardize the success of such offering. If the
Approved Underwriter believes that the registration of all or part of the
Registrable Securities which the Underwriting Initiating Holders and the other
Designated Holders have requested to be included would materially adversely
affect the success of such public offering, then the Company shall be required
to include in the underwritten offering, to the extent of the amount that the
Approved Underwriter believes may be sold without causing such adverse effect,
first, all of the Registrable Securities to be offered for the account
-----
of the  Designated Holders who requested inclusion of their Registrable
Securities pursuant to this Section 5(a), pro rata based on the number of
Registrable Securities owned by such Designated Holders; and second, any other
                                                             ------
securities requested to be included in such offering.  The Company shall use its
reasonable efforts to cause the Initial Shelf Registration to be declared
effective under the Securities Act as soon as practicable following the date of
the meeting of shareholders called to consider the Requisite Shareholder
Approvals but in any event no later than 180 days from the date hereof (the
"Effectiveness Deadline"), and to keep the Initial Shelf Registration
continuously effective under the Securities Act until the earlier of the
expiration of the Effectiveness Period or the date a Subsequent Shelf
Registration, as defined below, covering all of the Registrable Securities has
been declared effective under the Securities Act.

     (b)  Subsequent Shelf Registrations.  If the Initial Shelf Registration or
          ------------------------------
any Subsequent Shelf Registration, as defined below, ceases to be effective for
any reason as a result of the issuance of a stop order by the Commission at any
time during the Effectiveness Period, the Company shall use its reasonable
efforts to obtain the prompt withdrawal of any order suspending the
effectiveness thereof, and in any event shall within 30 days of such cessation
of effectiveness amend the Shelf Registration in a manner reasonably expected to
obtain the withdrawal of the order suspending the effectiveness thereof, or file
an additional Shelf Registration covering all of the Registrable Securities (a
"Subsequent Shelf Registration"). If a Subsequent Shelf Registration is filed,
the Company shall use its reasonable efforts to cause the Subsequent Shelf
Registration to be declared effective as soon as practicable after such filing
and to keep such Registration Statement continuously effective until the end of
the Effectiveness Period.

     (c)  Supplements and Amendments.  The Company shall supplement and amend
          --------------------------
the Shelf Registration if required by the rules, regulations or instructions
applicable to the registration form used by the Company for such Shelf
Registration, if required by the Securities Act, or if reasonably requested by
the holders of a majority of the Registrable Securities covered by such
Registration Statement or by any managing underwriter of such Registrable
Securities in the event of an underwritten offering of the Registrable
Securities.

     (d)  Notification of Terms.  At least five days prior to any sale of
          ---------------------
Registrable Securities pursuant to a registration under this Section 5 (other
than a sale in an Underwritten Offering), the Designated Holder shall advise the
Company in writing of the terms of such sale, including whether an investor
banking firm is used for purposes of such sale, and, if so, in what capacity and
under what compensation terms, and the proposed manner of distribution of the
Registrable Securities.

     (e)  Limitations on Shelf Registrations.  If the Board of Directors of the
          ----------------------------------
Company, in its good faith judgment, determines that any registration of
Registrable Securities should not be made or continued because it would
materially interfere with any material financing, acquisition, corporate
reorganization or merger or other material transaction involving the Company (a
"Valid Business Reason"), the Company may (x) postpone filing a Registration
Statement relating to a Shelf Registration until such Valid Business Reason no
longer exists, but in no event for more than thirty (30) days, and (y) in case a
Registration has been filed, if the Valid Business Reason has not resulted from
actions taken by the Company, the Company, upon the approval of a majority of
the Company's Board of Directors, may postpone amending or supplementing such
Registration Statement but in no event for more than thirty (30) days.  The
Company shall give written notice of its determination to postpone a
Registration Statement or an amendment or supplement of a Registration Statement
and of the fact that the Valid Business Reason for such postponement or
withdrawal no longer exists, in each case, promptly after the occurrencethereof.
Notwithstanding anything to the contrary contained herein, the Company may not
postpone a filing, an amendment or a supplement due to a Valid Business Reason
more than once in any twelve (12) month period.

     (f)  Expenses.  The Company shall bear all Registration Expenses in
          --------
connection with any Shelf Registration pursuant to this Section 3, whether or
not such Shelf Registration become effective.

     (g)  Selection of Underwriters.  If any Demand Registration or S-3
          -------------------------
Registration, as the case may be, of Registrable Securities is in the form of an
underwritten offering, the Company shall select and obtain an investment banking
firm of national reputation to act as the managing underwriter of the offering
(the "Approved Underwriter"); provided, however, that the Approved Underwriter
                              --------  -------
shall, in any case, also be approved by the Initiating Holders or S-3 Initiating
Holders, as the case may be, such approval not to be unreasonably withheld.

<PAGE>

                                                                               8

     (h)  Liquidated Damages.  In the event that the Initial Registration
          ------------------
Statement is not filed with the Commission on or prior to the Filing Date or has
not been declared effective by the Commission on or prior to the Effectiveness
Deadline (either such event, a "Registration Default"), then the Company shall
pay each Designated Holder of Registrable Securities liquidated damages in an
amount equal to one percent (1%) of the aggregate purchase price paid for the
Preferred Stock and Warrants that are convertible or exercisable for the
Registrable Securities per week that such Registration Default continues
("Liquidated Damages").  The Company shall not in any event be required to pay
Liquidated Damages for more than one Registration Default at any given time, and
upon cure of a Registration Default (by the filing or the declaration of
effectiveness of the Initial Registration Statement, as applicable) such
Liquidated Damages shall cease to accrue.  All accrued Liquidated Damages shall
be paid in cash to the Designated Holders entitled thereto, in proportion to the
aggregate number of Registrable Securities beneficially owned by each such
Designated Holder, on the last Business Day of each March, June, September and
December.

     4.  Incidental or "Piggy-Back" Common Stock Registration.
         ----------------------------------------------------

         (a)  Request for Incidental Registration  .  If the Company proposes to
              -----------------------------------
file a Registration Statement under the Securities Act with respect to an
offering of Common Stock by the Company for its own account (other than a
Registration Statement on Form S-4 or S-8 or any successor thereto) or for the
account of any stockholder of the Company other than the Designated Holders,
then the Company shall give written notice of such proposed filing to each of
the Designated Holders at least twenty (20) days before the anticipated filing
date, and such notice shall describe the proposed registration and distribution
and offer such Designated Holders the opportunity to register the number of
Registrable Securities as each such Designated Holder may request (an
"Incidental Registration").  The Company shall use its reasonable best efforts
(within twenty (20) days of the notice provided for in the preceding sentence)
to cause the managing underwriter or underwriters in the case of a proposed
underwritten offering (the "Company Underwriter") to permit each of the
Designated Holders who have requested in writing to participate in the
Incidental Registration to include its or his Registrable Securities in such
offering on the same terms and conditions as the securities of the Company or
the account of such other stockholder, as the case may be, included therein.  In
connection with any Incidental Registration under this Section 4(a) involving an
underwritten offering, the Company shall not be required to include any
Registrable Securities in such underwritten offering unless the Designated
Holders thereof accept the terms of the underwritten offering as agreed upon
between the Company, such other stockholders, if any, and the Company
Underwriter, and then only in such quantity as the Company Underwriter believes
will not jeopardize the success of the offering by the Company.  If the Company
Underwriter determines that the registration of all or part of the Registrable
Securities which the Designated Holders have requested to be included would
materially adversely affect the success of such offering, then the Company shall
be required to include in such Incidental Registration, to the extent of the
amount that the Company Underwriter believes may be sold without causing such
adverse effect, first, all of the securities to be
<PAGE>

                                                                               9

offered for the account of the Company; second, the Registrable Securities to be
                                        ------
offered for the account of the Designated Holders pursuant to this Section 4,
pro rata based on the number of Registrable Securities owned by each such
Designated Holder; and third, any other securities requested to be included in
                       -----
such offering.

         (b)  Expenses.  The Company shall bear all Registration Expenses in
              --------
connection with any Incidental Registration pursuant to this Section 4, whether
or not such Incidental Registration becomes effective.

     5.  Holdback Agreements.  Restrictions on Public Sale by Designated
         -------------------   -----------------------------------------
Holders.  To the extent requested (A) by the Company, in the case of a non-
-------
underwritten public offering, and (B) by the Approved Underwriter or the Company
Underwriter, as the case may be, in the case of an underwritten public offering,
and if all of the Company's officers, directors and holders in excess of five
percent (5%) of its outstanding capital stock execute agreements identical to
those referred to in this Section 5, each Designated Holder agrees not to effect
any public sale or distribution of any Registrable Securities or of any
securities convertible into or exchangeable or exercisable for such Registrable
Securities, including a sale pursuant to Rule 144 under the Securities Act,
during the ninety (90) day period or such shorter period, if any, mutually
agreed upon by such Designated Holder and the requesting party beginning on the
effective date of such Registration Statement (except as part of such
registration).  No Designated Holder of Registrable Securities subject to this
Section 5 shall be released from any obligation under any agreement, arrangement
or understanding entered into pursuant to this Section 5 unless all other
Designated Holders of Registrable Securities subject to the same obligation are
also released.

     6.  Registration Procedures.
         -----------------------

         (a)  Obligations of the Company.  Whenever the registration of the
              --------------------------
offering and sale of Registrable Securities is to be effected pursuant to
Section 3 or Section 4 of this Agreement, as applicable, the Company shall use
its reasonable best efforts to effect the registration and sale of such
Registrable Securities in accordance with the intended method of distribution
thereof as quickly as practicable, and in connection with any such request, the
Company shall, as expeditiously as possible:

selected by the Designated Holders holding a majority of the Registrable
Securities being registered in such registration ("Holders Counsel") and any
other Inspector with an adequate and appropriate opportunity to review and

filed with the Commission, subject to such documents being under the Company s

(including each preliminary prospectus) and any prospectus filed under Rule 424
under the Securities Act as each such seller may reasonably request in order to
facilitate the disposition of the Registrable Securities owned by such seller;

     (iv)   register or qualify such Registrable Securities under such other
securities or "blue sky" laws of such jurisdictions as any seller of Registrable
Securities may request, and to continue such qualification in effect in such
jurisdiction for as long as permissible pursuant to the laws of such
jurisdiction, or for as long as any such seller requests or until all of such
Registrable Securities are sold, whichever is shortest, and do any and all other
acts and things which may be reasonably necessary or advisable to enable any
such seller to consummate the disposition in such jurisdictions of the
Registrable Securities owned by such seller; provided, however, that the Company
                                             --------  -------
shall not be required to (x) qualify generally to do business in any
jurisdiction where it would not otherwise be required to qualify but for this
Section 6(a)(iv), (y) subject itself to taxation in any such jurisdiction or (z)
consent to general service of process in any such jurisdiction;

     (v)    notify each seller of Registrable Securities at any time when a
prospectus relating thereto is required to be delivered under the Securities
Act, upon discovery that, or upon the happening of any event as a result of
which, the prospectus included in such Registration Statement contains an untrue
statement of a material fact or omits to state any material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading and the Company shall
promptly prepare a supplement or amendment to such prospectus and furnish to
each seller of securities under such Registration Statement a reasonable number
of copies of such supplement to or an amendment of such prospectus as may be
necessary so that, after delivery to the

<PAGE>

                                                                              11

purchasers of such securities, such prospectus shall not contain an untrue

stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading;

     (vi)   enter into and perform customary agreements (including an

<PAGE>

                                                                              12

determines, in good faith, to be confidential and which it notifies the
Inspectors are confidential shall not be disclosed by the Inspectors (and the
Inspectors shall confirm their agreement in writing in advance to the Company if
the Company shall so request) unless (x) the disclosure of such Records is
necessary, in the Company s judgment, to avoid or correct a misstatement or
omission in the Registration Statement, (y) the release of such Records is
ordered pursuant to a subpoena or other order from a court of competent
jurisdiction after exhaustion of all appeals therefrom or (z) the information in
such Records was known to the Inspectors on a non-confidential basis prior to
its disclosure by the Company or has been made generally available to the
public.  Each seller of Registrable Securities agrees that it shall, upon
learning that disclosure of such Records is sought in a court of competent
jurisdiction, give notice to the Company and allow the Company, at the Company s
expense, to undertake appropriate action to prevent disclosure of the Records
deemed confidential;

the date such securities are delivered to the underwriters for sale pursuant to
such registration or, if such securities are not being sold through
underwriters, on the date the Registration Statement with respect to such
securities becomes effective, an opinion, dated such date, of counsel
representing the Company for the purposes of such registration, addressed to the
underwriters, if any, and to the seller making such request, covering such legal
matters with respect to the registration in respect of which such opinion is
<PAGE>

                                                                              13

and are customarily included in such opinions;

         (x)   comply with all applicable rules and regulations of the
Commission, and make available to its security holders, as soon as reasonably
practicable but no later than fifteen (15) months after the effective date of
the Registration Statement, an earnings statement covering a period of twelve
(12) months beginning after the effective date of the Registration Statement, in
a manner which satisfies the provisions of Section 11(a) of the Securities Act
and Rule 158 thereunder;

         (xi)   cause all such Registrable Securities to be listed on the
securities exchange on which securities issued by the Company are then listed,

registration of the Registrable Securities contemplated hereby.

    (b)  Seller Information.  The Company may require each seller of
          ------------------

     (c)  Notice to Discontinue.  Each Designated Holder agrees that, upon
          ---------------------

or a Shelf Registration pursuant to the terms of this Agreement, regardless of
whether such Registration Statement is declared effective.  All of the expenses
described in the preceding sentence of this Section 6(d) are referred to herein

shall have furnished any amendments or supplements thereto) or arising out of or
based upon 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 under the circumstances such statements were made, except insofar as
such Liability arises out of or is based upon any untrue statement or alleged

as the Company may reasonably request or as may be required by law for use in
connection with any such Registration Statement or prospectus and all
information required to be disclosed in order to make the information previously

receipt by the Indemnified Party of any written notice of the commencement of
any action, suit, proceeding or investigation or threat thereof made in writing
for which the Indemnified Party intends to claim indemnification or contribution
pursuant to this Agreement; provided, however, that the failure so to notify the

Indemnifying Party shall not relieve the Indemnifying Party of any Liability
that it may have to the Indemnified Party hereunder (except to the extent that
the Indemnifying Party is materially prejudiced or otherwise forfeits
substantive rights or defenses by reason of such failure).  If notice of
commencement of any such action is given to the Indemnifying Party as above
provided, the Indemnifying Party shall be entitled to participate in and, to the
extent it may wish, jointly with any other Indemnifying Party similarly
notified, to assume the defense of such action at its own expense, with counsel
chosen by it and reasonably satisfactory to such Indemnified Party.  The
Indemnified Party shall have the right to employ separate counsel in any such
action and participate in the defense thereof, but the fees and expenses of such
counsel shall be paid by the Indemnified Party unless (i) the Indemnifying Party
agrees to pay the same, (ii) the Indemnifying Party fails to assume the defense
of such action with counsel reasonably satisfactory to the Indemnified Party or
(iii) the named parties to any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party and such parties
have been advised by such counsel that either (x) representation of such
Indemnified Party and the Indemnifying Party by the same counsel would be
inappropriate under applicable standards of professional conduct or (y) there
may be one or more legal defenses available to the Indemnified Party which are
different from or additional to those available to the Indemnifying Party.  In
any of such cases, the Indemnifying Party shall not have the right to assume the
defense of such action on behalf of such Indemnified Party, it being understood,
however, that the Indemnifying Party shall not be liable for the fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) for all Indemnified Parties.  No Indemnifying Party shall be liable for
any settlement entered into without its written consent, which consent shall not
be unreasonably withheld.  No Indemnifying Party shall, without the consent of
such Indemnified Party, effect any settlement of any pending or threatened
proceeding in respect of which such Indemnified Party is a party and indemnity
has been sought hereunder by such Indemnified Party, unless such settlement
includes an unconditional release of such Indemnified Party from all liability
for claims that are the subject matter of such proceeding.

     (d)  Contribution.  If the indemnification provided for in this Section 8
          ------------
from the Indemnifying Party is unavailable to an Indemnified Party hereunder in
respect of any Liabilities referred to herein, then the Indemnifying Party, in
lieu of indemnifying such Indemnified Party, shall contribute to the amount paid
or payable by
<PAGE>

                                                                              17

such Indemnified Party as a result of such Liabilities in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party and
Indemnified Party in connection with the actions which resulted in such
Liabilities, as well as any other relevant equitable considerations. The
relative faults of such Indemnifying Party and Indemnified Party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission to state a material fact, has been made by, or relates to
information supplied by, such Indemnifying Party or Indemnified Party, and the
parties relative intent, knowledge, access to information and opportunity to
correct or prevent such action. The amount paid or payable by a party as a
result of the Liabilities referred to above shall be deemed to include, subject
to the limitations set forth in Sections 7(a), 7(b) and 7(c), any legal or other
fees, charges or expenses reasonably incurred by such party in connection with
any investigation or proceeding; provided that the total amount to be
                                 --------
contributed by such Designated Holder shall be limited to the net proceeds
received by such Designated Holder in the offering.

     The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 7(d) 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 paragraph.
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.  Rule 144.  The Company covenants that it shall (a) file any reports
         --------
required to be filed by it under the Exchange Act and (b) take such further
action as each Designated Holder may reasonably request (including providing any
information necessary to comply with Rule 144 under the Securities Act), all to
the extent required from time to time to enable such Designated Holder to sell
Registrable Securities without registration under the Securities Act within the
limitation of the exemptions provided by (i) Rule 144 under the Securities Act,
as such rule may be amended from time to time, or Regulation S under the
Securities Act or (ii) any similar rules or regulations hereafter adopted by the
Commission.  The Company shall, upon the request of any Designated Holder,
deliver to such Designated Holder a written statement as to whether it has
complied with such requirements.

     9.  Miscellaneous.
         -------------

         (a)  Recapitalizations, Exchanges, etc.    The Company shall cause any
              ----------------------------------
successor or assign (whether by merger, consolidation, sale of assets or
otherwise) to enter into a new registration rights agreement with the Designated
Holders on terms substantially the same as this Agreement as a condition of any
such transaction.

         (b)  No Inconsistent Agreements.  The Company represents and warrants
              --------------------------
that it has not granted to any Person the right to request or require the

to register any securities issued by the Company, other than the rights granted
to the Designated Holders herein and other than rights that would not be
inconsistent with the rights granted to the Designated Holders in this
Agreement. The Company shall not enter into any agreement with respect to its
securities that is inconsistent with the rights granted to the Designated
Holders in this Agreement or grant any additional registration rights to any
Person or with respect to any securities which are not Registrable Securities,
which are prior in right to or inconsistent with the rights granted in this
Agreement.

     (c)  Remedies.  The Designated Holders, in addition to being entitled to
          --------
exercise all rights granted by law, including recovery of damages, shall be
entitled to specific performance of their rights under this Agreement.  The
Company agrees that monetary damages would not be adequate compensation for any
loss incurred by reason of a breach by it of the provisions of this Agreement
and hereby agrees to waive in any action for specific performance the defense
that a remedy at law would be adequate.

     (d)  Amendments and Waivers.  Except as otherwise provided herein, the
          ----------------------
provisions of this Agreement may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof may not be given
unless consented to in writing by the Company and the Designated Holders holding
a majority of the aggregate number of Registrable Securities owned by all of the
Designated Holders.  Any such written consent shall be binding upon the Company
and all of the Designated Holders.
