                                    ---------

                       RESTRICTED STOCK PURCHASE AGREEMENT

         This Restricted Stock Agreement is made as of June 1, 2001, by DAOU
Systems, Inc., a Delaware corporation (the "Company"), and James Roberto
("Roberto").

                              Background Statement

         In connection with Roberto providing services to the Company pursuant
to an Employment Agreement of November 9, 2000 (the "Employment Agreement") and
                                                     --------------------
the Amendment No. 1 to the Employment Agreement, , effective as of June 1, 2001
("Amended Agreement"), the Company's Board of Directors has granted to Roberto
  -----------------
the right to purchase 1.5 million restricted shares of Common Stock of the
Company, which are subject to a limited repurchase right (such shares, as
adjusted for stock splits, recapitalizations, combinations and the like, are
hereinafter referred to as the "Restricted Shares"), at a purchase price of $
0.29 per share.

                                    Agreement

         The parties, intending to be legally bound, agree as follows:

1.       Grant of Award Subject to Right of Repurchase.

         1.1      Stock Award. The Company hereby agrees to issue to Roberto 1.5
                  -----------
million Shares of its Common Stock upon his payment to the Company of the
purchase price therefor of $0.29 per share, which shall be paid through his
execution and delivery of the promissory note attached hereto. The Shares shall
be subject to the limitations provided below in this Section 1.

         1.2      Scope of Repurchase Right. Five-Sixths (5/6ths) of the
                  -------------------------
Restricted Shares shall be subject to a limited right (but not an obligation) of
repurchase by the Company (the "Right of Repurchase"). Roberto shall not
transfer, assign, encumber or otherwise dispose of any unvested Restricted
Shares, except as provided in the following sentence. Roberto may transfer any
Restricted Shares, subject to the Right of Repurchase, (i) by beneficiary
designation, will or intestate succession or (ii) to Roberto's spouse, children
or grandchildren or to a trust or family limited partnership established by
Roberto for the benefit of Roberto or Roberto's spouse, children or
grandchildren, provided in either case that the Transferee agrees in writing on
a form prescribed by the Company to be bound by all provisions of this
Agreement. If Roberto transfers any Restricted Shares, then this Section 1 shall
apply to the Transferee to the same extent as to Roberto.

         1.3      Condition Precedent to Exercise. The Right of Repurchase may
                  -------------------------------
be exercised at any time during the term hereof and for up to sixty (60) days
following the termination of Roberto's Employment as that term is defined in the
Employment Agreement.

                                       4

<PAGE>

         1.4      Lapse of Repurchase Right. Roberto shall acquire a vested
                  -------------------------
interest in and the Company's Right of Repurchase shall lapse with respect to
1/36th of the Restricted Shares upon Roberto's completion of each of the next
thirty (30) months of continuous employment after the date hereof, such that
Roberto would be fully vested in the Restricted Shares at the expiration of
thirty (30) months from the date hereof. The Right of Repurchase shall lapse
with respect to an additional 500,000 restricted shares in the event the Company
terminates Roberto's Employment without Cause (as defined in the Employment
Agreement). In addition, the Right of Repurchase shall lapse with respect to all
remaining Restricted Shares if the Company is subject to a Change in Control (as
defined in the Employment Agreement) before Roberto's employment terminates.

         1.5      Repurchase Cost. If the Company exercises the Right of
                  ---------------
Repurchase, it shall pay Roberto an amount in cash or Cash Equivalents equal to
$.29 per share (equal to the purchase price) for each of the Restricted Shares
being repurchased. "Cash Equivalents" for purposes of this Agreement includes a
reduction of all or part of any unpaid interest and principal of the above
referenced promissory note.

         1.6      Exercise of Repurchase Right. The Right of Repurchase shall be
                  ----------------------------
exercisable only by written notice delivered to Roberto prior to the expiration
of the sixty (60) day period specified in Section 1.3 above. The notice shall
set forth the date on which the repurchase is to be effected. Such date shall
not be more than thirty (30) days after the date of the notice. The
certificate(s) representing the Restricted Shares to be repurchased shall, prior
to the close of business on the date specified for the repurchase, be delivered
to the Company properly endorsed for transfer. The Company shall, concurrently
with the receipt of such certificate(s), pay to Roberto the purchase price
determined according to Subsection 1.5 above. Payment shall be made in cash (or,
in the Company's sole discretion, by a reduction of any accrued and unpaid
interest or unpaid principal outstanding pursuant to the promissory note). The
Right of Repurchase shall terminate with respect to any Restricted Shares for
which it has not been timely exercised pursuant to this Subsection 1.6.

         1.7      Additional Shares or Substituted Securities. In the event of
                  -------------------------------------------
the declaration of a stock dividend, the declaration of an extraordinary
dividend payable in a form other than stock, a spin-off, a stock split, an
adjustment in conversion ratio, a recapitalization or a similar transaction
affecting the Company's outstanding securities without receipt of consideration,
any new, substituted or additional securities or other property (including money
paid other than as an ordinary cash dividend) that by reason of such transaction
are distributed with respect to any Restricted Shares or into which such
Restricted Shares thereby become convertible shall immediately be subject to the
Right of Repurchase. Appropriate adjustments to reflect the distribution of such
securities or property shall be made to the number and/or class of the
Restricted Shares. After each such transaction, appropriate adjustments shall
also be made to the price per share to be paid upon the exercise of the Right of
Repurchase in order to reflect any change in the Company's outstanding
securities effected without receipt of consideration therefor; provided,
however, that the aggregate purchase price payable for the Restricted Shares
shall remain the same.

         1.8      Termination of Rights as Stockholder. If the Company makes
                  ------------------------------------
available, at the time and place and in the amount and form provided in this
Agreement, the consideration for the Restricted Shares to be repurchased in
accordance with this Section 1, then after such time the

                                       5

<PAGE>

person from whom such Restricted Shares are to be repurchased shall no longer
have any rights as a holder of such Restricted Shares (other than the right to
receive payment of such consideration in accordance with this Agreement). Such
Restricted Shares shall be deemed to have been repurchased in accordance with
the applicable provisions hereof, whether or not the certificate(s) therefor
have been delivered as required by this Agreement.

         1.9      Escrow. The certificate(s) for Restricted Shares shall be
                  ------
deposited in escrow with the Company to be held in accordance with the
provisions of this Agreement. Any new, substituted or additional securities or
other property described in Section 1.7 above shall immediately be delivered to
the Company to be held in escrow, but only to the extent the Shares are at the
time Restricted Shares. All regular cash dividends on Restricted Shares (or
other securities at the time held in escrow) shall be paid directly to Roberto
and shall not be held in escrow. Restricted Shares, together with any other
assets or securities held in escrow hereunder, shall be (i) surrendered to the
Company for repurchase and cancellation upon the Company's exercise of its Right
of Repurchase or (ii) released to Roberto, within ten days of Roberto's request,
to the extent the Shares are vested, no longer subject to the repurchase right
herein and no longer pledged pursuant to that certain Stock Pledge Agreement,
dated of even date herewith by and between Roberto and the Company (the "Pledge
Agreement") (but not more frequently than once every six (6) months). In any
event, all Shares that have vested (and any other vested assets and securities
attributable thereto) and are no longer subject to the repurchase right and no
longer pledged pursuant to the Pledge Agreement, shall be released within sixty
(60) days after Roberto's cessation of Employment.

2.       Representations of Roberto. Roberto hereby represents, warrants,
         --------------------------
acknowledges, and agrees that Roberto has the power and authority to execute and
deliver this Agreement and to perform its obligations.

3.       Representations of the Company. The Company hereby represents,
         ------------------------------
warrants, acknowledges, and agrees that:

         3.1      The Company has full corporate power and authority to execute
and deliver this Agreement and to perform its obligations hereunder. This
Agreement constitutes the valid and legally binding obligation of the Company,
enforceable in accordance with its terms and conditions. The Company need not
give any notice to, make any filing with, or obtain any authorization, consent,
or approval of any government or governmental agency in order to consummate the
transactions contemplated by this Agreement.

         3.2      Neither the execution and the delivery of this Agreement, nor
the consummation of the transactions contemplated hereby, will violate any
constitution, statute, regulation, rule, injunction, judgment, order, decree,
ruling, charge, or other restriction of any government, governmental agency, or
court to which the Company is subject.

         3.3      When issued upon the terms and conditions of this Agreement
(and paid for as contemplated by this Agreement), the Shares will be validly
issued and fully paid and non-assessable, with no personal liability attached to
the ownership thereof and not subject to any preemptive rights, rights of first
refusal or other similar rights of the stockholders of the Company.

4.       Miscellaneous.
         -------------

         4.1      Market Stand-Off. In connection with any underwritten public
                  ----------------
offering by the Company of its equity securities pursuant to an effective
registration statement filed under the Securities Act, Roberto shall not,
without the prior written consent of the Company's managing underwriter, (i)
lend, offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or
warrant to purchase, or otherwise transfer or dispose of, directly or
indirectly, any shares of Common Stock of the Company ("Stock") or any
securities convertible into or exercisable or exchangeable for Stock (whether
such shares or any such securities are then owned by Roberto or are thereafter
acquired), or (ii) enter into any swap or other arrangement that transfers to
another, in whole or in part, any of the economic consequences of ownership of
the Stock, whether any such transaction described in clause (i) or (ii) above is
to be settled by delivery of Stock or such other securities, in cash or
otherwise. Such restriction (the "Market Stand-Off") shall be in effect for such
                                  ----------------
period of time following the date of the final prospectus for the offering as
may be requested by the Company or such underwriters. In no event, however,
shall such period exceed ninety (90) days. In the event of the declaration of a
stock dividend, a spin-off, a stock split, an adjustment in conversion ratio, a
recapitalization or a similar transaction affecting the Company's outstanding
securities without receipt of consideration, any new, substituted or additional
securities that are by reason of such transaction distributed with respect to
any shares of Stock subject to the Market Stand-Off, or into which such shares
thereby become convertible, shall immediately be subject to the Market
Stand-Off. In order to enforce the Market Stand-Off, the Company may impose
stop-transfer instructions with respect to the Stock until the end of the
applicable stand-off period. The Company's underwriters shall be beneficiaries
of the Agreement set forth in this Section 4.1. Roberto shall be subject to this
Subsection 4.1 only if all of the directors, officers and any five percent (5%)
or greater shareholders of the Company are subject to similar arrangements.

         4.2      Rights of the Company. The Company shall not be required to
                  ---------------------
(i) transfer on its books any Shares that have been sold or transferred in
contravention of this Agreement or (ii) treat as the owner of Shares, or
otherwise to accord voting, dividend or liquidation rights to, any transferee to
whom Shares have been transferred in contravention of this Agreement.

         4.3      Successors and Assigns. Except as otherwise expressly provided
                  ----------------------
to the contrary, the provisions of this Agreement shall inure to the benefit of,
and be binding upon, the Company and its successors and assigns and be binding
upon Roberto and Roberto's legal representatives, heirs, legatees, distributees,
assigns and transferees by operation of law, whether or not any such person has
become a party to this Agreement or has agreed in writing to join herein and to
be bound by the terms, conditions and restrictions hereof.

         4.4      No Retention of Rights. Nothing in this Agreement shall confer
                  ----------------------
upon Roberto any right to continue his employment for any period of specific
duration or interfere with or otherwise restrict in any way the rights of the
Company (or any Parent or Subsidiary employing or retaining Roberto) to
terminate Roberto's employment at any time and for any reason, with or without
cause, or of Roberto under any other Agreement between Roberto and the Company,
which rights are hereby expressly reserved by each.

<PAGE>

         4.5      Tax Election. Subjecting the Shares to a Right of Repurchase
                  ------------
may result in adverse tax consequences that may be avoided or mitigated by
filing an election under Code Section 83(b) of the Internal Revenue Code of
1986, as amended (the "Code"). Such election may be filed only within thirty
(30) days after the date of purchase. Roberto should consult with Roberto's tax
advisor to determine the tax consequences of subjecting the Shares to a Right of
Repurchase and the advantages and disadvantages of filing the Code Section 83(b)
election. Roberto acknowledges that it is Roberto's sole responsibility, and not
the Company's, to file a timely election under Code Section 83(b), even if
Roberto requests the Company or its representatives to make this filing
Roberto's behalf.

         4.6      Legend. All certificates evidencing Restricted Shares shall
                  ------
bear the following legends:

                  "THE SHARES REPRESENTED HEREBY MAY NOT BE SOLD, ASSIGNED,
                  TRANSFERRED, ENCUMBERED OR IN ANY MANNER DISPOSED OF, EXCEPT
                  IN COMPLIANCE WITH THE TERMS OF A WRITTEN AGREEMENT BETWEEN
                  COMPANY AND THE REGISTERED HOLDER OF THE SHARES (OR THE
                  PREDECESSOR IN INTEREST TO THE SHARES). SUCH AGREEMENT GRANTS
                  TO COMPANY CERTAIN REPURCHASE RIGHTS UPON TERMINATION OF
                  EMPLOYMENT WITH COMPANY. THE SECRETARY OF COMPANY WILL UPON
                  WRITTEN REQUEST FURNISH A COPY OF SUCH AGREEMENT TO THE HOLDER
                  HEREOF WITHOUT CHARGE."

         4.7      Notice. Any notice required by the terms of this Agreement
                  ------
shall be given in writing and shall be deemed effective upon personal delivery
or upon deposit with the United States Postal Service, by registered or
certified mail, with postage and fees prepaid. Notice shall be addressed to the
Company at its principal executive office and to Roberto at the address that
Roberto most recently provided to the Company.

         4.8      Entire Agreement. This Agreement constitutes the entire
                  ----------------
contract between the parties hereto with regard to the subject matter hereof. It
supersedes any other agreements, representations or understandings (whether oral
or written and whether express or implied) relating to the subject matter
hereof.

         4.9      Governing Law. This Agreement shall be governed by, and
                  -------------
construed in accordance with, the laws of the State of California, as such laws
are applied to contracts entered into and to be performed entirely within such
State.

         4.10     Amendments and Waivers. Any term of this Agreement may be
                  ----------------------
amended and the observance of any term of this Agreement may be waived (either
generally or in a particular instance and either retroactively or
prospectively), only with the written consent of the Company and the holders of
a majority of the then outstanding shares of the Company's capital stock that is
not owned by Roberto.

         4.11     Severability. If one or more provisions of this Agreement are
                  ------------
held to be unenforceable under applicable law, such provision shall be excluded
from this Agreement and the balance of the Agreement shall be interpreted as if
such provision were so excluded and shall be enforceable in accordance with its
terms.

         4.12     Counterparts. This Agreement may be executed in two or more
                  ------------
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

US $435,000                  San Diego, California                  June 1, 2001


         FOR VALUE RECEIVED, the undersigned, James Roberto ("Maker"), hereby
promises to pay to the order of DAOU Systems, Inc., a Delaware corporation (the
"Company"), the principal sum of Four Hundred and Thirty Five Thousand Dollars
($435,000) with interest on the unpaid balance thereof from the date that such
principal amount was advanced until maturity at the rate per annum equal to
6.75% (the "Applicable Rate") computed on the basis of a 365-day year and actual
days elapsed, both principal and interest payable as hereinafter provided in
lawful money of the United States of America at the offices of the Company in
San Diego, California, or at such other place as from time to time may be
designated by the holder of this Note.

         The outstanding principal balance of this Note and accrued interest
thereon shall be due and payable in full on or before May 31, 2006.

         Maker shall have the right to prepay, without penalty, upon ten (10)
business days' notice to the holder, at any time and from time to time prior to
maturity, all or any part of the unpaid principal balance of this Note.

         All payments or prepayments received hereunder, shall first be applied
to any costs or expenses of enforcing this Note, next to accrued, but unpaid
interest, and then to unpaid principal.

         It is the intent of the payee of this Note and the undersigned in the
execution of this Note to contract in strict compliance with applicable usury
law. In furtherance thereof, the said payee and the undersigned stipulate and
agree that none of the terms and provisions contained in this Note, or in any
other instrument executed in connection herewith, shall ever be construed to
create a contract to pay for the use, forbearance or detention of money,
interest at a rate in excess of the maximum interest rate permitted to be
charged by applicable law; that neither the undersigned nor any other parties
now or hereafter becoming liable for payment of this Note shall ever be
obligated or required to pay interest on this Note at a rate in excess of the
maximum interest that may be lawfully charged under applicable law; and that the
provisions of this paragraph shall control over all other provisions of this
Note and any other instruments now or hereafter executed in connection herewith
which may be in apparent conflict herewith. The term "applicable law" as used in
this Note shall mean the laws of the State of California or the laws of the
United States, whichever laws allow the greater rate of interest, as such laws
now exist or may be changed or amended or come into effect in the future.

         This Note is secured pursuant to the terms of that certain Stock Pledge
Agreement, dated of even date herewith, by and between the Company and Maker,
pursuant to which Maker pledges to the Company, and grants the Company a
security interest in 1.5 million shares of the

pursuant to that certain Stock Purchase Agreement of even date herewith, by and
between the Company and Maker, and any dividends or distribution received with
respect to, on account of, or in substitution for, the Pledged Shares.

         Should the indebtedness represented by this Note or any part thereof be
collected at law or in equity or through any bankruptcy, receivership, probate
or other court proceedings or if this Note is placed in the hands of attorneys
for collection after default, the undersigned and all endorsers, guarantors and
sureties of this Note jointly and severally agree to pay to the holder of this
Note in addition to the principal and interest due and payable hereon all the
costs and expenses of said holder in enforcing this Note including, without
limitation, reasonable attorneys' fees and legal expenses.

                                                        ------
that certain Stock Purchase Agreement, by and between the Company and Pledgor,

         As a material inducement for the Company to make the loan to Pledgor

interest in the Shares.

                                    Agreement

         NOW, THEREFORE, in consideration of the mutual terms, covenants and
conditions contained herein, the parties hereby agree as follows:

         1.       Security. The term "Pledged Stock" shall mean the 1.5 million

shall mean all of Pledgor's obligations, covenants and agreements under the

received, including as appropriate, Pledgor's endorsement or appropriate stock
power duly executed in blank, as appropriate, to be held by the Escrow Agent, as
a part of the Pledged Stock, subject to the terms hereof; provided, however,

will have sole voting rights with respect to the Pledged Stock.

and represents to the Company that: (a) he has the power and authority to enter
into this Agreement and has the power and authority to pledge the Pledged Stock
for the purposes described herein, (b) Pledgor is the legal and beneficial owner
of all of the Pledged Stock, (c) all of the shares of the Pledged Stock are
owned by Pledgor free of any pledge, mortgage, lien or security interest of any
kind, except as created hereby, (d) the execution and delivery by Pledgor of
this Agreement, and the performance of its terms, will not result in any
violation or default under the terms of any agreement or instrument, or any law
or governmental rule or regulation applicable to Pledgor or the Pledged Stock,
and (e) upon execution and delivery by Pledgor of this Agreement and upon
delivery of the Pledged Stock to Escrow Agent, this Agreement will create a
valid and perfected first priority security interest in the Pledged Stock, and
the proceeds thereof, subject to no prior security interest.

         6.       Transfer of Interests. Pledgor hereby covenants that, until
                  ---------------------
such time as the Obligations have been fully paid, performed and satisfied,
except as set forth in Section 1.2 of the Purchase Agreement, Pledgor will not
sell, convey or otherwise dispose of any of the Pledged Stock or any interest
therein, or create, incur or permit to exist any pledge, mortgage, lien, charge,
encumbrance or any security interest whatsoever in or with respect to any of the
Pledged Stock, or the proceeds thereof, other than the security interest created
hereby. No transfer shall be valid unless and until the transferee agrees that
such transfer is subject to the preexisting security interest created hereby and
such transferee executes a pledge agreement reasonably satisfactory to the
Company.

         7.       Default. As used herein, the term "Default" will mean the
                  -------                            -------
failure of full and timely payment or performance and satisfaction of any of the
Obligations.

         8.       Rights of the Company. Upon the occurrence of a Default, the
                  ---------------------
Company may, at its option, do any one or more of the following: (a) declare all
indebtedness of Pledgor to Company to be immediately due and payable, whereupon
all unpaid principal and interest under the Note will become and be immediately
due and payable; (b) exercise any and all of the rights and remedies of a
secured party as provided for by law; (c) proceed by an action or actions at law
or in equity to recover the obligations secured hereby or to foreclose under the
terms of this Agreement and the Note and sell the collateral, or any portion
thereof, pursuant to a judgment or decree of a court or courts of competent
jurisdiction; (d) proceed immediately to have any or all of the Pledged Stock
registered in the Company's name or in the name of a nominee; (e) enforce

                                       17

<PAGE>

one or more remedies hereunder, successively or concurrently; and (f) proceed
immediately to dispose of and realize upon the Pledged Stock, or any part
thereof, and in connection therewith, sell or otherwise dispose of and deliver
the Pledged Stock, or any part thereof, in one or more parcels at public or
private sale or sales, at any exchange, broker's board or at any of the
Company's offices or elsewhere, at such prices and on such terms as the Company
may deem best, for cash or on credit, or for future delivery without assumption
of any credit risk, with the right of the Company or any purchaser to purchase
at any such sale either the whole or any part of the Pledged Stock (in
connection with any such sale or disposition, the Company need not give more
than thirty (30) calendar days notice of the time and place of any public sale
or of the time after which a private sale may take place, which notice to
Pledgor hereby acknowledges to be reasonable).

         9.       Proceeds. The proceeds of any disposition of all or any part
                  --------
of the Pledged Stock, as provided in Section 8, will be applied as follows: (a)
                                     ---------
first, to the costs and expenses incurred in connection therewith or incidental
thereto, including the Company's attorneys' fees and legal expenses; (b) second,
to the satisfaction of the Obligations; (c) third, to the payment of any other
amounts required by applicable law; and (d) fourth, to Pledgor to the extent of
any surplus remaining. In the event that there is any deficiency due to the fact
that the proceeds from the aforesaid disposition of the Pledged Stock were
inadequate to satisfy the Obligations, Pledgor will not be liable to the Company
for such deficiency.

         10.      Private Sale. Pledgor recognize and acknowledge that the
                  ------------
company may be unable to effect a public sale of all or a part of the Pledged
Stock and may elect to resort to one or more private sales to purchasers who
will be obligated to agree, among other things, to acquire the Pledged Stock for
their own account, for investment, and not with a view to the distribution or
resale thereof. Pledgor acknowledges that any such private sales may be at
prices and on terms less favorable than those of public sales, and agrees that
such private sales will be deemed to have been made in a commercially reasonable
manner and that the Company has no obligation to delay sale of any Pledged Stock
to permit Pledgor to register it for public sale under the Securities Act of
1933, as amended.

         11.      Release of Pledged Stock . Upon the execution hereof, Pledgor
                  ------------------------
will deliver to Escrow Agent the stock certificates representing the Pledged
Stock, including Pledgor's endorsement thereon or appropriate stock powers duly
executed in blank, as appropriate, to be held by the Escrow Agent in accordance
with the terms of this Agreement and Section 1.9 of the Purchase Agreement.

         12.      Performance by Pledgor. Upon full payment and performance of
                  ----------------------
all of the Obligations by Pledgor and upon payment of all additional costs and
expenses provided herein, this Agreement will terminate, and the Company will
deliver or caused to be delivered to Pledgor, such of the Pledged Stock that has
not been sold or otherwise disposed of pursuant to this Agreement.

         13.      Remedies. The rights and remedies provided herein are
                  --------
cumulative and are in addition to, and not exclusive of, any rights or remedies
provided in other instruments and agreements between the Company and Pledgor, or
as provided by law.

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

                          REGISTRATION RIGHTS AGREEMENT


         This Registration Rights Agreement, dated as of June 1, 2001, is among
DAOU Systems, Inc., a Delaware corporation (the "Company"), and James Roberto
(the "Investor")."

                                    RECITALS

         WHEREAS, the Company and the Investor are parties to that certain
Restricted Stock Agreement, dated June 1, 2001 (the "Purchase Agreement"); and

         WHEREAS, the Parties desire to enter into an agreement concerning the
registration of the shares of common stock, par value $.001 per share (the
"Common Stock"), to be issued pursuant to the Purchase Agreement.

         NOW, THEREFORE, the parties hereby agree as follows:

                                   ARTICLE I
                               REGISTRATION RIGHTS

1.1.     Definitions. For purposes of this Agreement:

(a)      the term "Register," "Registered," and "Registration" refer to a
registration effected by preparing and filing a registration statement or
similar document in compliance with the Securities Act of 1933, as amended (the
"Act"), and the declaration or ordering of effectiveness of such registration
statement or document;

(b)      the term "Registrable Securities" means the Common Stock issued
pursuant to the Purchase Agreement, excluding in all cases, however, any
Registrable Securities sold by a person in a transaction in which such person's
rights under this Article I are not assigned;

(c)      the number of shares of "Registrable Securities then outstanding" will
be the number of shares of Common Stock outstanding which are Registrable
Securities;

(d)      the term "Holder" means any person owning or having the right to
acquire Registrable Securities or any permitted assignee thereof; and

(e)      the term "Form S-1" means such form under the Act as in effect on the
date of this Agreement or any registration form under the Act subsequently
adopted by the Securities and Exchange Commission ("SEC") which permits
inclusion or incorporation of substantial information by reference to other
documents filed by the Company with the SEC.

                                       22

<PAGE>

1.2.     Form S-1 Registration.

         As soon as reasonably practicable after the written request of the
Holders of a majority of the Registrable Securities, the Company shall file with
the SEC one or more Registration Statements on Form S-1 (or other similar form)
covering the continuous sale of the Registrable Securities pursuant to Rule 415
under the Securities Act or any successor thereto (each, a "Shelf Registration
Statement"), in the manner specified therein. The Company shall use all
reasonable efforts to cause each Shelf Registration Statement to be declared
effective by the SEC as soon as reasonably practicable after its filing with the
SEC, and upon reasonable notice from a Holder (and in any event no less than ten
(10) days) that the Holder intends to sell pursuant to a Shelf Registration
Statement, the Company will file such amendments and supplements as necessary to
update the Shelf Registration Statement so that it will be effective for any
such sale of Registrable Securities until the earlier of (x) such time as all of
the Registrable Securities are sold pursuant to such Shelf Registration
Statement or (y) each Holder is able to sell within any ninety (90) day period
all Registrable Securities owned by such Holder pursuant to SEC Rules as then in
effect, including Rule 144 under the Securities Act, or any successor thereto
("SEC Rule 144") (the "Effective Period"); provided that in the event that
Company determines in good faith that, because it has under consideration a
significant (as defined under Regulation S-X of the SEC) acquisition or
disposition or other material transaction or corporate event that has not been
publicly disclosed or that it is in the process of preparing for filing with the
SEC an Annual Report on Form 10-K, a Quarterly Report on Form 10-Q or a Current
Report on Form 8-K or other form, a Shelf Registration Statement may contain a
material misstatement or omission, the Company may cause such Shelf Registration
Statement to not be used during the period in question. The Company agrees it
will use its best efforts to ensure that such deferral will be for the shortest
period of time reasonably required not exceeding, in the aggregate, ninety (90)
days in any twelve (12) month period.

1.3.     Company Registration.

         In the event that (i) the Company fails to satisfy its obligations
pursuant to Section 1.2 or (ii) for any period of not less than thirty (30)
consecutive days a Shelf Registration Statement may not be used for any reason,
and if (but without any obligation to do so) the Company proposes to register
(including for this purpose a registration effected by the Company for
shareholders other than the Holders) any of its stock or other securities under
the Act in connection with the public offering of such securities solely for
cash (other than a registration relating solely to the sale of securities to
participants in a Company stock plan, or a registration on any form which does
not include substantially the same information as would be required to be
included in a registration statement covering the sale of the Registrable
Securities), the Company will, at such time, promptly give each Holder written
notice of such registration. Upon the written request of each Holder given
within twenty (20) days after mailing of such notice by the Company in
accordance with Section 2.5, the Company will cause to be registered under the
Act all of the Registrable Securities that each such Holder has requested to be
registered.

                                       23

1.4.     Obligations of the Company.

         Except as otherwise expressly specified in this Agreement, whenever
required under this Article I to effect the registration of any Registrable
Securities, the Company will, as expeditiously as reasonably practicable:

(a)      Prepare and file with the SEC such amendments and supplements to such
registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

(b)      Furnish to the Holders such number of copies of a prospectus, including
a preliminary prospectus, in conformity with the requirements of the Act, and
such other documents as they may reasonably request in order to facilitate the
disposition of Registrable Securities owned by them.

(c)      Use its best efforts to register and qualify the securities covered by
such registration statement under such other securities or Blue Sky laws of such
jurisdictions as will be reasonably requested by the Holders, provided that the
Company will not be required in connection therewith or as a condition thereto
to qualify to do business or to file a general consent to service of process in
any such states or jurisdictions.

1.5.     Furnish Information.

         It will be a condition precedent to the obligations of the Company to
take any action pursuant to this Article I with respect to the Registrable
Securities of any selling Holder that such Holder will furnish to the Company
such information regarding itself, the Registrable Securities held by it, the
intended method of disposition of such securities and all of the other pertinent
information as will be required to effect the registration of such Holder's
Registrable Securities.

1.6.     Expenses of Registration.

         Subject to restrictions under applicable state securities laws, all
expenses other than underwriting discounts and commissions incurred in
connection with registrations, filings or qualifications pursuant to Sections
1.2 and 1.3, including (without limitation) all registration, filing and
qualification fees, printers' and accounting fees, and fees and disbursements of
counsel for the Company and the reasonable fees and disbursements of one counsel
representing the Holders will be borne by the Company.

1.7.     Indemnification. If any Registrable Securities are included in a
         registration statement under this Article I:

(a)      To the extent permitted by law, the Company will indemnify and hold
harmless each Holder, each of its directors and each of its officers, any
underwriter (as defined in the Act) for such Holder and each person, if any, who
controls such Holder or underwriter within the meaning of the Act or the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), against any
losses, claims, damages, or liabilities (joint or several) to which they may
become subject under the Act, or the Exchange Act, insofar as such losses,
claims, damages,

                                       24

<PAGE>

or liabilities (or actions in respect thereof) arise out of or are based upon
any of the following statements, omissions or violations (collectively a
"Violation"): (i) any untrue statement or alleged untrue statement of a material
fact contained in such registration statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto, (ii) 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, or (iii) any violation or alleged violation by the
Company of the Act, the Exchange Act, or any rule or regulation promulgated
under the Act, or the Exchange Act; and the Company will pay to each such
Holder, director, officer, underwriter or controlling person, any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity agreement contained in this Subsection 1.7(a) will not apply
to amounts paid in settlement of any such loss, claim, damage, liability, or
action if such settlement is effected without the consent of the Company (which
consent will not be unreasonably withheld), nor will the Company be liable in
any such case for any such loss, claim, damage, liability, or action to the
extent that it arises out of or is based upon a Violation which occurs in
reliance upon and in conformity with written information furnished expressly for
use in connection with such registration by any such Holder, director, officer,
underwriter or controlling person.

(b)      To the extent permitted by law, each selling Holder will indemnify and
hold harmless the Company, each of its directors, each of its officers who has
signed the registration statement, each person, if any, who controls the Company
within the meaning of the Act, any other Holder selling securities in such
registration statement and any controlling person of any such underwriter or
other Holder, against any losses, claims, damages, or liabilities (joint or
several) to which any of the foregoing persons may become subject, under the Act
or the Exchange Act insofar as such losses, claims, damages, or liabilities (or
actions in respect thereto) arise out of or are based upon any Violation, in
each case to the extent (and only to the extent) that such Violation occurs in
reliance upon and in conformity with written information furnished by such
Holder expressly for use in connection with such registration; and each such
Holder will pay any legal or other expenses reasonably incurred by any person
intended to be indemnified pursuant to this Subsection 1.7(b), in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the indemnity agreement contained in this
Subsection 1.7(b) will not apply to amounts paid in settlement of any such loss,
claim, damage, liability or action if such settlement is effected without the
consent of the Holder, which consent will not be unreasonably withheld;
provided, that, in no event will any indemnity under this Subsection 1.7(b)
exceed the proceeds from the offering net of sales commission, if any, received
by such Holder.

(c)      Promptly after receipt by an indemnified party under this Section 1.7
of notice of the commencement of any action (including any governmental action),
such indemnified party will, if a claim in respect thereof is to be made against
any indemnifying party under this Section 1.7, deliver to the indemnifying party
a written notice of the commencement thereof and the indemnifying party will
have the right to participate in, and, to the extent the indemnifying party so
desires, jointly with any other indemnifying party similarly noticed, to assume
the defense thereof with counsel satisfactory to the indemnified party (which
shall not unreasonably withhold its approval); provided, however, that an
indemnified party

                                       25

<PAGE>

(together with all other indemnified parties which may be represented without
conflict by one counsel) will have the right to retain one separate counsel,
with the reasonable fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party is inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, will relieve such
indemnifying party of any liability to the indemnified party under this Section
1.7, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 1.7.

(d)      If the indemnification provided for in this Section 1.7 is held by a
court of competent jurisdiction to be unavailable to an indemnified party with
respect to any loss, liability, claim, damage, or expense referred to therein,
then the indemnifying party, in lieu of indemnifying such indemnified party to
this Agreement, will 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 that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party will 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.

(e)      The obligations of the Company and Holders under this Section 1.7 will
survive the completion of any offering of Registrable Securities in a
registration statement under this Article I, and otherwise.

1.8.     Reports Under 1934 Act.

         With a view to making available to the Holders the benefits of Rule 144
promulgated under the Act and any other rule or regulation of the SEC that may
at any time permit a Holder to sell securities of the Company to the public
without registration or pursuant to a registration on Form S-1, the Company
will:

(a)      make and keep public information available, as those terms are
understood and defined in SEC Rule 144, at all times;

(b)      file with the SEC in a timely manner all reports and other documents
required of the Company under the Act and the Exchange Act; and

(c)      furnish to any Holder, so long as the Holder owns any Registrable
Securities, forthwith upon request (i) a written statement by the Company that
it has complied with the reporting requirements of SEC Rule 144, the Act and the
Exchange Act, or that it qualifies as

                                       26

<PAGE>

a registrant whose securities may be resold pursuant to Form S-3 (at any time
after it so qualifies), (ii) a copy of the most recent annual or quarterly
report of the Company and such other reports and documents so filed by the
Company, and (iii) such other information as may be reasonably requested in
availing any Holder of any rule or regulation of the SEC which permits the
selling of any such securities without registration or pursuant to such form.

1.9.     Rule 144 Availability.

         Notwithstanding anything to the contrary above in this Article I, prior
to exercising any right provided for in this Article I each Holder will (i)
evaluate in good faith whether such Holder is otherwise permitted to sell the
entire amount of Registrable Securities it is then seeking to register within
the time period it desires to sell pursuant to Rule 144 of the Exchange Act, or
any successor regulation thereto and (ii) exercise such rights only in the case
that it determines in good faith that such rights are necessary to sell such
Registrable Securities in a timely manner.

                                   ARTICLE II
                                  MISCELLANEOUS

2.1.     Successors and Assigns.

         Except as otherwise provided in this Agreement, the terms and
conditions of this Agreement will inure to the benefit of and be binding upon
the respective successors and assigns of the parties (including transferees of
any shares of Registrable Securities). Nothing in this Agreement, express or
implied, is intended to confer upon any party other than the parties to this
Agreement or their respective successors and assigns any rights, remedies,
obligations, or liabilities under or by reason of this Agreement, except as
expressly provided in this Agreement.

         This Agreement will be governed by and construed under the laws of the
State of Delaware.

2.3.     Counterparts.

and the same instrument.

2.4.     Titles and Subtitles.

         The titles and subtitles used in this Agreement are used for
convenience only and are not to be considered in construing or interpreting this
Agreement.

2.5.     Notices.

         Unless otherwise provided, any notice required or permitted under this
Agreement will be given in writing and will be deemed effectively given upon
personal delivery to the party to be notified, by telecopy upon the appropriate
answer-back, or upon deposit with the United States Post Office, by registered
or certified mail, postage prepaid and addressed to the party to be

                                       27

<PAGE>

notified at the address indicated for such party on Schedule 1 or at such other
address as such party may designate by ten (10) days' advance written notice to
the other parties.

2.6.     Expenses.

         If any action at law or in equity is necessary to enforce or interpret
the terms of this Agreement, the prevailing party will be entitled to reasonable
attorneys' fees, costs and necessary disbursements in addition to any other
relief to which such party may be entitled.

2.7.     Amendments and Waivers.

         Any term of this Agreement may be amended and the observance of any
term of this Agreement may be waived (either generally or in a particular
instance and either retroactively or prospectively), only with the written
consent of the Company and the Holders of a majority of the Registrable
Securities then outstanding. Any amendment or waiver effected in accordance with
this paragraph will be binding upon each Holder of any Registrable Securities
then outstanding, each future Holder of all such Registrable Securities, and the
Company.

2.8.     Severability.

         If one or more provisions of this Agreement are held to be
unenforceable under applicable law, such provision will be excluded from this
Agreement and the balance of the Agreement will be interpreted as if such
provision were so excluded and will be enforceable in accordance with its terms.

2.9.     Aggregation of Stock.

         All shares of Registrable Securities held or acquired by affiliated
entities or persons will be aggregated together for the purpose of determining
the availability of any rights under this Agreement.

2.10.    Entire Agreement, Amendment, Waiver.

         This Agreement (including the Schedules to this Agreement, if any)
constitutes the full and entire understanding and agreement between the parties
with regard to the subjects of this Agreement and thereof.

2.11.    Adjustments for Stock Splits.

         Wherever in this Agreement there is a reference to a specific number of
shares of Common Stock of the Company of any class or series, or a reference to
any amount of dollars per any such share, then, upon the occurrence of any
subdivision, combination or stock dividend of such class or series of stock, the
specific number of shares or the specific dollar amount so referenced in this
Agreement will automatically be proportionately adjusted to reflect the effect
on the outstanding shares of such class of series of stock by such subdivision,
combination or stock dividend.
