respects or if the Company receives any notification with respect to the
suspension of the qualification of the Registrable Securities for sale in any
jurisdiction or the initiation of any proceeding for such purpose, (E) of the
happening of any event during the period the registration statement is effective

untrue statement of a material fact or omits to state a material fact required
to be stated therein or necessary to make statements therein not misleading (in
the case of a prospectus, in light of circumstances under which they were made)
and (F) of any determination by the Company that a post-effective amendment to

      If the notification relates to an event described in clauses (E) or (F),

                  (a) The Company will indemnify and hold harmless to the
fullest extent permitted by law each Holder of Registrable Securities and each
of its officers, directors and partners, and each person controlling such
Holder, with respect to which such registration, qualification or compliance has
been effected pursuant to this Agreement, and each underwriter, if any, and each
person who controls any underwriter of the Registrable Securities held by or
issuable to such Holder, against all claims, losses, expenses, damages and
liabilities (or actions in respect thereto) arising out of or based on (i) any
untrue statement (or alleged untrue statement) of a material fact contained in
any registration statement under which such securities were registered under the
Securities Act or the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading; (ii) any untrue statement (or alleged untrue statement) of a
material fact contained in any preliminary or final prospectus, or based on any
omission (or alleged omission) to state therein a material fact required to be
stated therein or necessary to make the statement therein, in light of the
circumstances under which they were made, or not misleading, or (iii) any
violation or alleged violation by the Company of the Securities Act, the
Exchange Act or any state securities law applicable to the Company or any rule
or regulation promulgated under the Securities Act, the Exchange Act or any such
state law and relating to action or inaction required of the Company in
connection with any such registration, qualification of compliance, and will
reimburse each such Holder, each of its officers, directors and partners, and
each person controlling such Holder, each such underwriter and each person who
controls any such underwriter, within five days from the date incurred for any
reasonable legal and any other expenses incurred in connection with
investigating, defending or settling any such claim, loss, damage, liability or
action; provided, however, that the indemnity agreement contained in this
subsection 1.5(a) shall not apply to amounts paid in settlement of any such
claim, loss, damage, liability, or action if such settlement is effected without
the consent of the Company (which consent shall not be unreasonably withheld);
and provided further, that the Company will not be liable in any such case to
the extent that any such claim, loss, damage or liability arises out of or is
based on any untrue statement or omission based upon written information
furnished to the Company in writing by such Holder or underwriter specifically
for use therein; and provided further, however, that the Company will not be
liable in any such case to the extent that any such claim, loss, damage or
liability arises directly out of or is based primarily upon an untrue statement
or omission made in any preliminary or final prospectus if (i) such Holder
failed to send or deliver a copy of the final prospectus or prospectus
supplement with or prior to the delivery of written confirmation of the sale of
the Registrable Securities and (ii) the final prospectus or prospectus
supplement would have corrected such untrue statement or omission, provided that
the Company had previously notified such Holder in writing that the prospectus
is outdated or defective. The Company shall notify the Holders promptly of the
institution, threat or assertion of any Proceeding arising from or in connection
with the transactions contemplated by this Agreement of which the Company is
aware.

<PAGE>

                  (b) Each Holder will, if Registrable Securities held by or
issuable to such Holder are included in the securities as to which such
registration, qualification or compliance is being effected, severally and not
jointly, indemnify and hold harmless to the fullest extent permitted by law the
Company, each of its directors and officers, each underwriter, if any, of the
Company's securities covered by such a registration statement, each person who
controls the Company within the meaning of the Securities Act, and each other
such Holder, each of its officers, directors and partners and each person
controlling such Holder, against all claims, losses, expenses, 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 or final prospectus, 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 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 or prospectus in reliance upon and in conformity with information
furnished to the Company in writing by such Holder specifically for use therein,
and will reimburse the Company, such Holders, such directors, officers,
partners, persons or underwriters for any reasonable legal or any other expenses
incurred in connection with investigating, defending or settling 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 or prospectus in
reliance upon and in conformity with information furnished to the Company by
such Holder specifically for use therein; provided, however, that the indemnity
agreement contained in this subsection 1.5(b) shall not apply to amounts paid in
settlement of any such claim, loss, damage, liability or action if such
settlement is effected without the consent of the Holder (which consent shall
not be unreasonably withheld); and provided further, that the total amount for
which any Holder shall be liable under this subsection 1.5(b) shall not in any
event exceed the net proceeds received by such Holder from the sale of
Registrable Securities held by such Holder in such registration giving rise to
such indemnification obligation; and provided further, that a Holder will not be
liable in any such case to the extent that any such claim, loss, damage or
liability arises out of or is based on any untrue statement or omission based
upon written information furnished to the Holder by the Company or underwriter
specifically for use therein.

                  (c) Each party entitled to indemnification under this
subsection 1.5 (the "Indemnified Party") shall give notice to the party required
to provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom; provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (whose approval shall not be
unreasonably withheld), and the Indemnified Party may participate in such
defense at such party's expense; and provided further, that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations hereunder, except to the extent such
failure resulted in material prejudice to the Indemnifying Party; and provided
further, that an Indemnified Party (together with all other Indemnified Parties
which may be represented without conflict by one counsel) shall have the right
to retain one separate counsel, with the fees and expenses to be paid by the
Indemnifying Party, if representation of such Indemnified Party by the counsel
retained by the Indemnifying Party would be inappropriate due to actual or
potential differing interests between such Indemnified Party and any other party
represented by such counsel in such proceeding. No Indemnifying Party, in the
defense of any such claim or litigation, shall, except with the consent of each
Indemnified Party, consent to entry of any judgment or enter into any settlement
which does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such Indemnified Party of a release from all liability
in respect to such claim or litigation.

<PAGE>

                  (d) If for any reason the foregoing indemnity is unavailable
or is insufficient to hold harmless an indemnified party under subsection 1.5,
then each Indemnifying Party shall contribute to the amount paid or payable by
such Indemnified Party as a result of any claim in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party, on the one
hand, and the Indemnified Party, on the other hand, with respect to such
offering of securities. The 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 or alleged omission to state a material fact relates to
information supplied by the Indemnifying Party or the Indemnified Party and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statement or omission. If, however, the
allocation provided in the second preceding sentence is not permitted by
applicable law, then each Indemnifying Party shall contribute to the amount paid
or payable by such Indemnified Party in such proportion as is appropriate to
reflect not only such relative faults, but also any other relevant equitable
considerations. The parties hereto agree that it would not be just and equitable
if contributions pursuant to this subsection 1.5(d) were to be determined by pro
rata allocation or by any other method of allocation which does not take into
account the equitable considerations referred to in the preceding sentences of
this subsection 1.5(d). The amount paid or payable in respect of any claim shall
be deemed to include any legal or other expenses reasonably incurred by such
Indemnified Party in connection with investigating or defending any such claim.
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. Notwithstanding
anything in this subsection 1.5 to the contrary, no Indemnifying Party (other
than the Company) shall be required pursuant to this subsection 1.5(d) to
contribute any amount in excess of the net proceeds received by such
Indemnifying Party from the sale of Registrable Securities in the offering to
which the losses, claims, damages or liabilities of the Indemnified Parties
relate, less the amount of any indemnification payment made pursuant to
subsection 1.5.

                  (e) The indemnity and contribution agreements contained herein
shall be in addition to any other rights to indemnification or contribution
which any Indemnified Party may have pursuant to law or contract and shall
remain operative and in full force and effect regardless of any investigation
made or omitted by, or on behalf of, any Indemnified Party and shall survive the
transfer of the Registrable Securities by any such party.

            1.6 Information by Holder. The Company may require each selling
Holder to furnish to the Company a certified statement as to the number of
shares of Common Stock beneficially owned by such Holder and, if required by the
SEC, the person thereof that has voting and dispositive control over the Shares.

            1.7 Rule 144 Reporting. With a view to making available to Holders

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

                  (c) so long as a Holder owns any Registrable Securities, to
furnish to such Holder forthwith upon receipt of a written request a written
statement by the Company as to its compliance with the reporting requirements of
said Rule 144 and of the Securities Act and the Exchange Act, a copy of the most
recent annual or quarterly report of the Company, and such other reports and

respective rights hereunder in the manner and to the Persons as permitted under
the Purchase Agreement

            1.9 [RESERVED].

            1.10 Delay of Registration. No Holder shall have any rights to take
any actions to restrain, enjoin, or otherwise delay any registration as the

implementation of this Section 1.

            1.11 Termination of Registration Rights. No Holder shall be entitled
to exercise any right provided for in this Section 1 at any time, and the

respect to such Holder, when all Registrable Securities covered by such
Registration Statement have been sold or may be sold without volume restrictions
pursuant to Rule 144(k) as determined by the counsel to the Company pursuant to
a written opinion letter to such effect, addressed and acceptable to the
Company's transfer agent and the affected Holders (the "Effectiveness Period").

      2. General.

            2.1 Waivers and Amendments. With the written consent of the record
holders of at least a 30% of the Registrable Securities, the obligations of the
Company and the rights of the parties under this Agreement may be waived (either
generally or in a particular instance, either retroactively or prospectively,
and either for a specified period of time or indefinitely), and with the same
consent the Company, when authorized by resolution of its Board of Directors,
may enter into a supplementary agreement for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Agreement; provided, however, that no such modification, amendment or
waiver shall reduce the aforesaid percentage of Registrable Securities without
the consent of all of the Holders of the Registrable Securities. Upon the
effectuation of each such waiver, consent, agreement of amendment or
modification, the Company shall promptly give written notice thereof to the
record holders of the Registrable Securities who have not previously consented
thereto in writing. This Agreement or any provision hereof may be changed,
waived, discharged or terminated only by a statement in writing signed by the
party against which enforcement of the change, waiver, discharge or termination
is sought, except to the extent provided in this subsection 2.1. In the event
the Company enters into a Subsequent Financing, and upon the request of the
Company, each Purchaser shall execute the registration rights agreement entered
into by the investors in such Subsequent Financing (on a pari passu basis with
such investors) and this Agreement shall be terminated.

            2.2 Governing Law/Consent to Jurisdiction. All questions concerning
the construction, validity, enforcement, interpretation of, and venue for any
dispute under this Agreement shall be determined with the provisions of the
Purchase Agreement.

            2.3 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.

            2.4 Entire Agreement. Except as set forth below, this Agreement and
the other documents delivered pursuant hereto constitute the full and entire
understanding and agreement between the parties with regard to the subjects
hereof and thereof, and this Agreement shall supersede and cancel all prior
agreements between the parties hereto with regard to the subject matter hereof.

            2.5 Notices, etc. Any and all notices or other communications or
deliveries required or permitted to be provided hereunder shall be delivered as
set forth in the Purchase Agreement

            2.6 Severability. In case any provision of this Agreement shall be
invalid, illegal, or unenforceable, the validity, legality and enforceability of
the remaining provisions of this Agreement or any provision of the other
Agreement s shall not in any way be affected or impaired thereby.

            2.7 Titles and Subtitles. The titles of the sections and subsections
of this Agreement are for convenience of reference only and are not to be
considered in construing this Agreement.

            2.8 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be an original, but all of which together
shall constitute one instrument. In the event that any signature is delivered by
facsimile transmission, such signature shall create a valid binding obligation
of the party executing (or on whose behalf such signature is executed) the same
with the same force and effect as if such facsimile signature were the original
thereof.

            2.9 Independent Nature of Holders' Obligations and Rights. The
obligations of each Holder hereunder are several and not joint with the
obligations of any other Holder hereunder, and no Holder shall be responsible in
any way for the performance of the obligations of any other Holder hereunder.
Nothing contained herein or in any other agreement or document delivered at any
closing, and no action taken by any Holder pursuant hereto or thereto, shall be
deemed to constitute the Holders as a partnership, an association, a joint
venture or any other kind of entity, or create a presumption that the Holders
are in any way acting in concert with respect to such obligations or the
transactions contemplated by this Agreement. Each Holder shall be entitled to
protect and enforce its rights, including without limitation the rights arising
out of this Agreement, and it shall not be necessary for any other Holder to be
joined as an additional party in any proceeding for such purpose.

            2.10 No Inconsistent Agreements. Neither the Company nor any of its
subsidiaries has entered, as of the date hereof, nor shall the Company or any of
its subsidiaries, on or after the date of this Agreement, enter into any
agreement with respect to its securities, that would have the effect of
impairing the rights granted to the Holders in this Agreement or otherwise
conflicts with the provisions hereof. Except as set forth on Schedule 2.10,
neither the Company nor any of its subsidiaries has previously entered into any
agreement granting any registration rights with respect to any of its securities
to any Person that have not been satisfied in full. No Person has any right to
cause the Company to effect the registration under the Securities Act of any
securities of the Company. The Company shall not file any other registration
statements until a registration statement covering the resale of the Registrable
Securities is declared effective by the SEC.

            2.11 Remedies. In the event of a breach by the Company or by a
Holder, of any of their obligations under this Agreement, each Holder or the
Company, as the case may be, in addition to being entitled to exercise all
rights granted by law and under this Agreement, including recovery of damages,
will be entitled to specific performance of its rights under this Agreement. The
Company and each Holder agree that monetary damages would not provide adequate
compensation for any losses incurred by reason of a breach by it of any of the
provisions of this Agreement and hereby further agrees that, in the event of any
action for specific performance in respect of such breach, it shall waive the
defense that a remedy at law would be adequate.

                              Plan of Distribution

      Each Selling Stockholder (the "Selling Stockholders") of the common stock
("Common Stock") of [_______, a [______ corporation (the "Company") and any of
their pledgees, assignees and successors-in-interest may, from time to time,
sell any or all of their shares of Common Stock on the Trading Market or any
other stock exchange, market or trading facility on which the shares are traded
or in private transactions. These sales may be at fixed or negotiated prices. A
Selling Stockholder may use any one or more of the following methods when
selling shares:

      o     ordinary brokerage transactions and transactions in which the
            broker-dealer solicits purchasers;

      o     block trades in which the broker-dealer will attempt to sell the
            shares as agent but may position and resell a portion of the block
            as principal to facilitate the transaction;

      o     purchases by a broker-dealer as principal and resale by the
            broker-dealer for its account;

      o     an exchange distribution in accordance with the rules of the
            applicable exchange;

      o     privately negotiated transactions;

      o     settlement of short sales entered into after the effective date of
            the registration statement of which this prospectus is a part;

      o     broker-dealers may agree with the Selling Stockholders to sell a
            specified number of such shares at a stipulated price per share;

      o     a combination of any such methods of sale;

      o     through the writing or settlement of options or other hedging
            transactions, whether through an options exchange or otherwise; or

      o     any other method permitted pursuant to applicable law.

      The Selling Stockholders may also sell shares under Rule 144 under the
Securities Act of 1933, as amended (the "Securities Act"), if available, rather
than under this prospectus.

      Broker-dealers engaged by the Selling Stockholders may arrange for other
brokers-dealers to participate in sales. Broker-dealers may receive commissions
or discounts from the Selling Stockholders (or, if any broker-dealer acts as
agent for the purchaser of shares, from the purchaser) in amounts to be
negotiated, but, except as set forth in a supplement to this Prospectus, in the
case of an agency transaction not in excess of a customary brokerage commission
in compliance with NASDR Rule 2440; and in the case of a principal transaction a
markup or markdown in compliance with NASDR IM-2440.


                                      A-1
<PAGE>

      In connection with the sale of the Common Stock or interests therein, the
Selling Stockholders may enter into hedging transactions with broker-dealers or
other financial institutions, which may in turn engage in short sales of the
Common Stock in the course of hedging the positions they assume. The Selling
Stockholders may also sell shares of the Common Stock short and deliver these
securities to close out their short positions, or loan or pledge the Common
Stock to broker-dealers that in turn may sell these securities. The Selling
Stockholders may also enter into option or other transactions with
broker-dealers or other financial institutions or the creation of one or more
derivative securities which require the delivery to such broker-dealer or other
financial institution of shares offered by this prospectus, which shares such
broker-dealer or other financial institution may resell pursuant to this
prospectus (as supplemented or amended to reflect such transaction).

      The Selling Stockholders and any broker~dealers or agents that are
involved in selling the shares may be deemed to be "underwriters" within the
meaning of the Securities Act in connection with such sales. In such event, any
commissions received by such broker~dealers or agents and any profit on the
resale of the shares purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act. Each Selling Stockholder has
informed the Company that it does not have any written or oral agreement or
understanding, directly or indirectly, with any person to distribute the Common
Stock. In no event shall any broker-dealer receive fees, commissions and markups
which, in the aggregate, would exceed eight percent (8%).

      The Company is required to pay certain fees and expenses incurred by the
Company incident to the registration of the shares. The Company has agreed to
indemnify the Selling Stockholders against certain losses, claims, damages and
liabilities, including liabilities under the Securities Act.

      Because Selling Stockholders may be deemed to be "underwriters" within the
meaning of the Securities Act, they will be subject to the prospectus delivery
requirements of the Securities Act. In addition, any securities covered by this
prospectus which qualify for sale pursuant to Rule 144 under the Securities Act
may be sold under Rule 144 rather than under this prospectus. Each Selling
Stockholder has advised us that they have not entered into any written or oral
agreements, understandings or arrangements with any underwriter or broker-dealer
regarding the sale of the resale shares. There is no underwriter or coordinating
broker acting in connection with the proposed sale of the resale shares by the
Selling Stockholders.


                                      A-2

      We agreed to keep this prospectus effective until the earlier of (i) the
date on which the shares may be resold by the Selling Stockholders without
registration and without regard to any volume limitations by reason of Rule
144(e) under the Securities Act or any other rule of similar effect or (ii) all
of the shares have been sold pursuant to the prospectus or Rule 144 under the
Securities Act or any other rule of similar effect. The resale shares will be
sold only through registered or licensed brokers or dealers if required under
applicable state securities laws. In addition, in certain states, the resale
shares may not be sold unless they have been registered or qualified for sale in
the applicable state or an exemption from the registration or qualification
requirement is available and is complied with.

         Under applicable rules and regulations under the Exchange Act, any
person engaged in the distribution of the resale shares may not simultaneously
engage in market making activities with respect to the Common Stock for the
applicable restricted period, as defined in Regulation M, prior to the
commencement of the distribution. In addition, the Selling Stockholders will be
subject to applicable provisions of the Exchange Act and the rules and
regulations thereunder, including Regulation M, which may limit the timing of
purchases and sales of shares of the Common Stock by the Selling Stockholders or
any other person. We will make copies of this prospectus available to the
Selling Stockholders and have informed them of the need to deliver a copy of
this prospectus to each purchaser at or prior to the time of the sale.
