               (j)  The number of shares of "Registrable Securities" outstanding

Registrable Securities.

               (k)  The term "SEC" shall mean the Securities and Exchange
Commission.

          1.2  Request for Registration.

               (a)  Subject to the conditions of this Section 1.2, if the
Company shall receive at any time after the earlier of (i) one (1) year after
the date of this Agreement or (ii) six (6) months after the effective date of
the Initial Offering, a written request from (1) the Holders of a majority of
the outstanding Series C Preferred Stock and the Series D Preferred Stock,
voting together as a single class; or (2) the Holders of a majority of the
outstanding Registrable Securities (voting together on an as converted basis)
that the Company file a registration statement under the Act covering the
registration of at least $10 million of Registrable Securities (in each such
case, the "Initiating Holders"), then the Company, shall within twenty (20) days
of the receipt thereof, give written notice of such request to all Holders, and
subject to the limitations of this Section 1.2, use its best efforts to effect,
as soon as practicable, the registration under the Act of all Registrable
Securities that the Holders request to be registered in a written request
received by the Company within twenty (20) days of receipt of the Company's
notice pursuant to this Section 1.2(a).

               (b)  If the Initiating Holders intend to distribute the
Registrable Securities covered by their request by means of an underwriting,
they shall so advise the Company as a part of their request made pursuant to
this Section 1.2 and the Company shall include such information in the written
notice referred to in Section 1.2(a). In such event the right of any Holder

                                       2


to include its Registrable Securities in such registration shall be conditioned
upon such Holder's participation in such underwriting and the inclusion of such
Holder's Registrable Securities in the underwriting (unless otherwise mutually
agreed by a majority in interest of the Initiating Holders and such Holder) to
the extent provided herein. All Holders proposing to distribute their securities
through such underwriting shall enter into an underwriting agreement in
customary form with the underwriter or underwriters selected for such
underwriting by a majority in interest of the Initiating Holders and reasonably
satisfactory to the Company subject to the limitations set forth in Section 1.12
hereof. Notwithstanding any other provision of this Section 1.2, if the
underwriter advises the Company that marketing factors require a limitation of
the number of securities underwritten (including Registrable Securities), then
the Company shall so advise all Holders of Registrable Securities that would
otherwise be underwritten pursuant hereto, and the number of shares that may be
included in such registration shall be allocated first to the Holders of Series
C Preferred Stock and the Series D Preferred Stock (or common stock issued upon
the conversion thereof) on a pro rata basis based on the number of Registrable
Securities held by such Holders and then to other Holders of such Registrable
Securities on a pro rata basis based on the number of Registrable Securities
held by such other Holders (including the Initiating Holders); provided that the
Holders of the Series C Preferred Stock and the Series D Preferred Stock may
exercise this right to priority on only one occasion based upon a majority vote
by the Holders of Series C Preferred Stock and Series D Preferred Stock, voting
together as a single class. All other cutbacks shall be made on a pro rata basis
based upon the number of Registrable Securities held by such Holders; provided,
however, that the number of shares of Registrable Securities to be included in
such underwriting shall not be reduced unless all other securities are entirely
excluded from such underwriting. Any Registrable Securities excluded or
withdrawn from such underwriting shall be withdrawn from the registration.

               (c)  The Company shall not be required to effect a registration
pursuant to this Section 1.2:

                    (i)   in any particular jurisdiction in which the Company
would be required to execute a general consent to service of process in
effecting such registration, unless the Company is already subject to service in
such jurisdiction and except as may be required under the Act, or

                    (ii)  after the Company has effected four (4) registrations
pursuant to this Section 1.2 ((A) two of which shall have been effected at the
request of the Holders of a majority of the Series A Preferred Stock and the
Series B Preferred Stock, voting together as a single class; and (B) two (2) of
which shall have been effected at the request of the Holders of a majority of
the Series C Preferred Stock and the Series D Preferred Stock, voting together
as a single class), and such registrations have been declared or ordered
effective; provided, however, that in the event that the number of Registrable
Securities included in any registration pursuant to this Section 1.2 is reduced
by more than fifty percent (50%) of the number of Registrable Securities
proposed to be offered pursuant to Section 1.2(b) above in any offering, then
the Company shall not have the right under this Section 1.2(c)(ii) to refuse to
effect a registration until a total of five (5) registrations pursuant to this
Section 1.2 have been effected and such registrations have been declared or
ordered effective (provided that any such fifth registration granted pursuant to
this subparagraph (ii) shall be allocated to the holders of the Series C
Preferred Stock and the Series D Preferred Stock voting together as a single
class); or

                    (iii) during the period starting with the date forty-five
(45) days prior to the Company's good faith estimate of the date of the filing
of, and ending on a date one

                                       3


hundred eighty (180) days following the effective date of, a Company-initiated
registration subject to Section 1.3 below, provided that the Company is actively
employing in good faith all reasonable efforts to cause such registration
statement to become effective; or

                    (iv)  if the Initiating Holders propose to dispose of
Registrable Securities that may be registered on Form S-3 pursuant to Section
1.4 hereof; or

                    (v)   if the Company shall furnish to Holders requesting a
registration statement pursuant to this Section 1.2, a certificate signed by the
Company's Chief Executive Officer or Chairman of the Board stating that in the
good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its shareholders for such registration
statement to be effected at such time, in which event the Company shall have the
right to defer such filing for a period of not more than one hundred twenty
(120) days after receipt of the request of the Initiating Holders, provided that
such right to delay a request shall be exercised by the Company not more than
once in any twelve (12)-month period.

          1.3  Company Registration.

               (a)  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
equity securities under the Act in connection with the public offering of such
securities (other than a registration relating solely to the sale of securities
to participants in a Company stock plan, a registration relating to a corporate
transaction under Rule 145 of the Act, a registration on any form that 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, or
a registration in which the only Common Stock being registered is Common Stock
issuable upon conversion of debt securities that are also being registered), the
Company shall, at such time, promptly give each Holder at least thirty (30) days
prior written notice of such registration. Upon the written request of each
Holder given within twenty (20) days after receipt of such notice by the Company
in accordance with Section 4.5, the Company shall, subject to the provisions of
Section 1.3(c), use all reasonable efforts to cause to be registered under the
Act all of the Registrable Securities that each such Holder has requested to be
registered.

               (b)  Right to Terminate Registration. The Company shall have the
                    -------------------------------
right to terminate or withdraw any registration initiated by it under this
Section 1.3 prior to the effectiveness of such registration whether or not any
Holder has elected to include securities in such registration. The expenses of
such withdrawn registration shall be borne by the Company in accordance with
Section 1.7 hereof.

               (c)  Underwriting Requirements. In connection with any offering
                    -------------------------
involving an underwriting of shares of the Company's capital stock, the Company
shall not be required under this Section 1.3 to include any of the Holders'
securities in such underwriting unless they accept the terms of the underwriting
as agreed upon between the Company and the underwriters selected by it (or by
other persons entitled to select the underwriters) and enter into an
underwriting agreement in customary form subject to the limitations set forth in
Section 1.11 hereof, with an underwriter or underwriters selected by the
Company, and then only in such quantity as the underwriters determine in their
sole discretion will not jeopardize the success of the offering by the Company.
If the total amount of securities, including Registrable Securities, requested
by shareholders to be included in such offering exceeds the amount of securities
sold other than by the Company that the underwriters determine in their sole
discretion is compatible with the success of the offering, then the Company
shall be required to include in the offering only that number of such

                                       4


securities, including Registrable Securities, that the underwriters determine in
their sole discretion will not jeopardize the success of the offering (the
securities so included to be apportioned pro rata among the selling Holders
according to the total amount of securities entitled to be included therein
owned by each selling Holder or in such other proportions as shall mutually be
agreed to by such selling Holders), but in no event shall (i) the amount of
securities of the selling Holders included in the opening be reduced below
thirty percent (30%) of the total amount of securities included in such
offering, unless such offering is the initial public offering of the Company's
securities, in which case the selling Holders may be excluded if no other
shareholder's securities are included, or (ii) notwithstanding (i) above, any
shares being sold by a shareholder exercising a demand registration right
similar to that granted in Section 1.2 be excluded from such offering, (iii) the
number of shares of Registrable Securities to be included in such underwriting
(excluding any Registrable Securities held by Common Holders) be reduced unless
all Registrable Securities held by the Common Holders are first entirely
excluded from such underwriting or (iv) the number of shares of Registrable
Securities to be included in such underwriting (excluding any Registrable
Securities held by Common Holders) be reduced unless all shares that are not
Registrable Securities that are held by any other person including, without
limitation, any person who is an employee, officer or director of the Company
(or any subsidiary of the Company) shall first be entirely excluded from such
underwriting. For purposes of the preceding parenthetical concerning
apportionment, for any selling shareholder that is a Holder of Registrable
Securities and that is a partnership or corporation, the partners, retired
partners and shareholders of such Holder, or the estates and family members of
any such partners and retired partners and any trusts for the benefit of any of
the foregoing persons shall be deemed to be a single "selling Holder," and any
pro rata reduction with respect to such "selling Holder" shall be based upon the
aggregate amount of Registrable Securities owned by all such related entities
and individuals.

          1.4  Form S-3 Registration.

               In case the Company shall receive from any Holder or Holders of
Registrable Securities then outstanding a written request or requests that the
Company effect a registration on Form S-3 and any related qualification or
compliance with respect to all or a part of the Registrable Securities owned by
such Holder or Holders, the Company shall:

               (a)  promptly give written notice of the proposed registration,
and any related qualification or compliance, to all other Holders, and

               (b)  use its best efforts to effect, as soon as practicable, such
registration and all such qualifications and compliances as may be so requested
and as would permit or facilitate the sale and distribution of all or such
portion of such Holders' Registrable Securities as are specified in such
request, together with all or such portion of the Registrable Securities of any
other Holders joining in such request as are specified in a written request
given within fifteen (15) days after receipt of such written notice from the
Company, provided, however, that the Company shall not be obligated to effect
any such registration, qualification or compliance, pursuant to this section
1.4:

                    (i)  if Form S-3 is not available for such offering by the
Holders;

                    (ii) if the Holders, together with the holders of any other
securities of the Company entitled to inclusion in such registration, propose to
sell Registrable Securities and such other securities (if any) at an aggregate
price to the public of less than $500,000;

                                       5


                         (iii) if the Company shall furnish to the Holders a
certificate signed by the Chief Executive Officer or Chairman of the Board of
the Company stating that in the good faith judgment of the Board of Directors of
the Company, it would be seriously detrimental to the Company and its
shareholders for such Form S-3 Registration to be effected at such time, in
which event the Company shall have the right to defer the filing of the Form S-3
registration statement for a period of not more than one hundred twenty (120)
days after receipt of the request of the Holder or Holders under this Section
1.4; provided, however, that the Company shall not utilize this right more than
once in any twelve month period;

                         (iv)  if the Company has, within the twelve (12) month
period preceding the date of such request, already effected one such
registration on Form S-3 for the Holders pursuant to this Section 1.4; or

                         (v)   in any particular jurisdiction in which the
Company would be required to qualify to do business or to execute a general
consent to service of process in effecting such registration, qualification or
compliance, unless the Company is currently qualified to do business or has
previously executed a general consent to service of process in such jurisdiction
and except as may be required under the Act.

                    (c)  Subject the foregoing, the Company shall file a
registration statement covering the Registrable Securities and other securities
so requested to be registered as soon as practicable after receipt of the
request or requests of the Holders. Registrations effected pursuant to this
Section 1.4 shall not be counted as requests for registration effected pursuant
to Sections 1.2.

          1.5  Obligations of the Company.

               Whenever required under this Section 1 to effect the registration
of any Registrable Securities, the Company shall, as expeditiously as reasonably
possible:

                    (a)  prepare and file with the SEC a registration statement
with respect to such Registrable Securities and use all reasonable efforts to
cause such registration statement to become effective, and, upon the request of
the Holders of a majority of the Registrable Securities registered thereunder,
keep such registration statement effective for a period of up to one hundred
twenty (120) days or, if earlier, until the distribution contemplated in the
Registration Statement has been completed; provided, however, that such 120 day
period shall be extended for a period of time equal to the period the Holder
refrains from selling any securities included in such registration at the
request of an underwriter of Common Stock (or other securities) of the Company;

                    (b)  prepare and file with the 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,

                    (c)  furnish to the Holders such numbers 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;

                    (d)  use all reasonable efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders, provided that the Company shall not be

                                       6


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

                    (e)  in the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement, in usual and
customary form with the managing underwriter of such offering;

                    (f)  notify each Holder of Registrable Securities covered by
such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Act or the happening of any event as a result
of which the prospectus included in such registration statement, as then in
effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing;

                    (g)  cause all such Registrable Securities registered
pursuant hereunder to be listed on each securities exchange on which similar
securities issued by the Company are then listed;

                    (h)  provide a transfer agent and registrar for all
Registrable Securities registered pursuant hereunder and a CUSIP number for all
such Registrable Securities, in each case not later than the effective date of
such registration; and

                    (i)  use its best efforts to furnish, at the request of any
Holder requesting registration of Registrable Securities pursuant to this
Section 1, on the date that such Registrable Securities are delivered to the
underwriters for sale in connection with a registration pursuant to this Section
1 (to the extent required by the underwriters), if such securities are being
sold through underwriters, or, if such securities are not being sold through
underwriters, on the date that the registration statement with respect to such
securities becomes effective, (i) an opinion, dated such date, of the counsel
representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and to the Holders requesting
registration of Registrable Securities and (ii) a letter dated such date, from
the independent certified public accountants of the Company, in form and
substance as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering, addressed to the underwriters,
if any, and to the Holders requesting registration of Registrable Securities.

          1.6  Information from Holder.

               It shall be a condition precedent to the obligations of the
Company to take any action pursuant to this Section 1 with respect to the
Registrable Securities of any selling Holder that such Holder shall furnish to
the Company such information regarding itself, the Registrable Securities held
by it, and the intended method of disposition of such securities as shall be
required to effect the registration of such Holder's Registrable Securities.

          1.7  Expenses of Registration.

               All expenses (other than underwriting discounts and commissions)
incurred in connection with registrations, filings or qualifications pursuant to
Sections 1.2, 1.3 and 1.4, including (without limitation) all registration,
filing and qualification fees, printers' and accounting fees, fees and
disbursements of counsel for the Company and the reasonable fees and
disbursements of one counsel for the selling Holders shall be borne by the
Company. Notwithstanding the

                                       7


foregoing, the Company shall not be required to pay for any expenses of any
registration proceeding begun pursuant to Section 1.2 or Section 1.4 if the
registration request is subsequently withdrawn at the request of the Holders of
a majority of the Registrable Securities to be registered (in which case all
participating Holders shall bear such expenses pro rata based upon the number of
Registrable Securities that were to be requested in the withdrawn registration),
unless, in the case of a registration requested under Section 1.2, the Holders
of a majority of the Registrable Securities agree to forfeit their right to one
demand registration pursuant to Section 1.2; provided further, however, that if
at the time of such withdrawal, either (a) the Holders have learned of a
material adverse change in the condition, business or prospects of the Company
from that known to the Holders at the time of their request and have withdrawn
the request with reasonable promptness following disclosure by the Company of
such material adverse change; or (b) the Company has exercised its right to
delay such registration as provided in Section 1.2(c)(v) or Section 1.4(b)(iii),
and the Holders have withdrawn the request with reasonable promptness following
notice by the Company of its exercise of such right, then the Holders shall not
be required to pay any of such expenses and shall retain their rights pursuant
to Section 1.2.

          1.8  Indemnification.

               In the event any Registrable Securities are included in a
registration statement under this Section 1;

                    (a)  To the extent permitted by law, the Company will
indemnify, and hold harmless each Holder, the partners, retired partners,
officers, directors and shareholders of each Holder, legal counsel and
accountants for each Holder, any underwriter (as defined the Act) for such
Holder and each person, if any, who controls any of the foregoing persons or
entities within the meaning of the Act or the 1934 Act, joint and severally
against any losses, claims, damages or liabilities to which they may become
subject under the Act, the 1934 Act or any federal or state securities law
insofar as such losses, claims, damages, 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 1934 Act, any federal or
state securities laws or any rule or regulations promulgated under the Act, the
1934 Act or any federal or state securities laws; and the Company will reimburse
each such Holder, underwriter, controlling person or person intended to be
indemnified pursuant to this subsection l.8(a) (as such expenses are incurred)
for 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
1.8(a) shall 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 shall not be unreasonably withheld), nor shall 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 that
occurs in reliance upon and in conformity with written information furnished
expressly for use in connection with such registration by such Holder,
underwriter or controlling person; provided further, however, that the foregoing
indemnity agreement with respect to any preliminary prospectus shall not inure
to the benefit of any Holder or underwriter, or any person controlling such
Holder or underwriter, from whom the person asserting any such losses, claims,
damages or liabilities purchased shares in the

                                       8


offering, if a copy of the prospectus (as then amended or supplemented if the
Company shall have furnished any amendments or supplements thereto) was
furnished to such Holder by the Company but was not sent or given by or on
behalf of such Holder or underwriter to such person, if required by law so to
have been delivered by, in the case of any underwriter by or on behalf of such
underwriter, or in the case of any Holder by such Holder or Holder's broker or
dealer, at or prior to the written confirmation of the sale of the shares to
such person, and if the prospectus (as so amended or supplemented) would have
cured the defect giving rise to such loss, claim, damage or liability.

                    (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, legal counsel and
accountants for the Company, any underwriter, 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, the 1934 Act or any state securities laws, 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 connection with
such registration; and each such Holder will reimburse any person intended to be
indemnified pursuant to this subsection l.8(b) for any legal or other expenses
reasonably incurred by such person in connection with investigating or defending
any such loss, claim, damage, liability or action; provided, however, that the
indemnity agreement contained in this subsection 1.8(b) shall 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
shall not be unreasonably withheld), provided that in no event shall any
indemnity under this subsection 1.8(b), together with the amount of any
contribution under Section 1.8(d), exceed the net proceeds from the offering
received by such Holder; provided further, however, that the foregoing indemnity
agreement with respect to any preliminary prospectus shall not inure to the
benefit of any party, or any person controlling such party, from whom the person
asserting any such losses, claims, damages or liabilities purchased shares in
the offering, if a copy of the prospectus (as then amended or supplemented if
the Company shall have furnished any amendments or supplements thereto) was not
sent or given by or on behalf of such party, if required by law so to have been
delivered by or on behalf of such party seeking indemnification hereunder, at or
prior to the written confirmation of the sale of the shares to such person
asserting any such losses, claims, damages or liabilities, and if the prospectus
(as so amended or supplemented) would have cured the defect giving rise to such
loss, claim, damage or liability.

                    (c)  Promptly after receipt by an indemnified party under
this Section l.8 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 1.8, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall 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 mutually
satisfactory to the parties, provided however, that an indemnified party
(together with all other indemnified parties that 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

                                       9


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, shall relieve such indemnifying party of
any liability to the indemnified party under this Section 1.8, 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 1.8.

                    (d)  If the indemnification provided for in this Section 1.8
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
herein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, claim, damage or expense
in such proportion as is appropriate to reflect the relative fault of the
indemnifying party on the one hand and of the indemnified party on the other in
connection with the statements or omissions that resulted in such loss,
liability, claim, damage or expense, as well as any other relevant equitable
considerations; provided that in no event shall any contribution under this
subsection 1.8(d), together with the amount of any indemnification from such
Holder pursuant to Section 1.8(b), exceed the net proceeds from the offering
received by such Holder. The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

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

                    (f)  The obligations of the Company and Holders under this
Section 1.8 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section l, and otherwise.

          1.9  Reports Under Securities Exchange Act of 1934.

               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-3, the
Company agrees to:

                    (a)  make and keep public information available, as those
terms are understood and defined in SEC Rule 144, at all times after ninety (90)
days after the effective date of the first registration statement filed by the
Company;

                    (b)  file with the SEC in a timely manner all reports and
other documents required of the Company under the Act and the 1934 Act;

                    (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 (at
any time after ninety (90) days after the effective date of the first
registration statement filed by the Company), the Act and the 1934 Act (at any
time after it has become subject to such reporting requirements), or that it
qualifies as a registrant whose securities may be resold pursuant to Form S-3
(at any time after it so qualifies), (ii)

                                      10


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 that permits the selling of any such securities without
registration or pursuant to such form, and

                    (d)  take such action, including the voluntary registration
of its Common Stock under Section 12 of the 1934 Act, as is reasonably necessary
to enable the Holders to utilize Form S-3 for the sale of their Registrable
Securities, such action to be taken as soon as practicable after the end of the
fiscal year in which the first registration statement filed by the Company for
the offering of its securities to the general public is declared effective.

          1.10 Assignment of Registration Rights.

               The rights to cause the Company to register Registrable
Securities pursuant to this Section 1 may be assigned (but only with all related
obligations) by a Holder to a transferee or assignee of such securities that (i)
is a direct or indirect partner, limited partner or retired partner of a Holder
(or a spouse, former spouse or member of such partner's, limited partner's or
retired partner's immediate family, or a custodian, trustee (including a trustee
of a voting trust), executor, or other fiduciary for the account of such
partner, limited partner or retired partner or his or her spouse, former spouse
or immediate family members); provided that after such assignment or transfer,
such direct or indirect partner, limited partner or retired partner holds at
least 50,000 shares of Registrable Securities (as adjusted for subsequent stock
dividends, splits or combinations), and provided further that such limitation
shall terminate and be of no force and effect upon the sale of the Company's
Common Stock in a firm commitment underwritten public offering pursuant to a
registration statement on form S-1 or SB-2 under the Act, as amended, (ii) an
Affiliate (as defined in Rule 405 under the Act) of the Holder, (iii) after such
assignment or transfer the transferee holds at least 100,000 shares of
Registrable Securities (as adjusted for subsequent stock dividends, splits or
combinations) or (iv) is, in the case of a Common Holder, a spouse or member of
such Common Holder's immediate family, or a custodian, trustee (including a
trustee of a voting trust), executor, or other fiduciary for the account of such
Common Holder's spouse or members of such Common Holder's immediate family, or a
trust for such Common Holder's own self, or a charitable remainder trust,
provided: (a) the Company is, within a reasonable time after such transfer,
furnished a written notice of the name and address of such transferee or
assignee and the securities with respect to which such registration rights are
being assigned; (b) such transferee or assignee agrees in writing to be bound by
and subject to the terms and conditions of this Agreement, including without
limitation the provisions of Section 1.12 below; and (c) such assignment shall
be effective only if immediately follow such transfer the further disposition of
such securities by the transferee or assignee is restricted under the Act.

          1.11 Limitations on Subsequent Registration Rights.

               From and after the date of this Agreement, the Company shall not,
without the prior written consent of (i) the Holders of a majority of the Series
C Preferred Stock and the Series D Preferred Stock, voting together as a single
class; and (ii) the Holders of a majority of the Registrable Securities
(excluding the Series C Preferred Stock and the Series D Preferred Stock),
voting together as a single class, enter into any agreement with any holder or
prospective holder of any securities of the Company that would allow such holder
or prospective holder (a) to include such securities in any registration filed
under Section 1.3 or 1.4 hereof, unless under the terms of such agreement, such
holder or prospective holder may include such securities in any such
registration only to the extent that the inclusion of such securities will not
reduce the amount of the Registrable

                                      11


Securities of the Holders that are included or (b) to demand registration of
their securities.

          1.12 "Market Stand-Off" Agreement.

               Each Holder hereby agrees that, if requested by the Company and
the managing underwriters, it will not, without the prior written consent of the
managing underwriter, during the period commencing on the date of the final
prospectus relating to the Company's Initial Offering and ending on the date
specified by the Company and the managing underwriter (such period not to exceed
one hundred eighty (180) days) (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 or any securities
convertible into or exercisable or exchangeable for Common Stock (whether such
shares or any such securities are then owned by the Holder or are, except in the
open market, 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 Common Stock or securities convertible into, or
exercisable or exchangeable for, Common Stock whether any such transaction
described in clause (i) or (ii) above is to be settled by delivery of Common
Stock or such other securities, in cash or otherwise. The foregoing provisions
of this Section 1.12 shall apply only to the Company's initial public offering
of equity securities, shall not apply to the sale of any shares to an
underwriter pursuant to an underwriting agreement, and shall only be applicable
to the Holders if all officers and directors and greater than one percent (1%)
shareholders of the Company enter into similar agreements (each, a "Restricted
Person," and collectively, the "Restricted Persons"), shall not apply to
transactions related to shares of Common Stock or other securities acquired in
open market transactions after the completion of the public offering and shall
not apply to the transfer of any Common Stock or other securities to a direct or
indirect partner, limited partner or retired partner of a Holder (or a spouse,
former spouse or member of such partner's, limited partner's or retired
partner's immediate family, or a custodian, trustee (including a trustee of a
voting trust), executor, or other fiduciary for the account of such partner,
limited partner or retired partner or his or her spouse, former spouse or
immediate family members), or to the estate of any such partner or retired
partner of a Holder, provided, however, that in such case, it shall be a
condition to the transfer that the transferee execute an agreement, in a form
acceptable to the underwriters, stating that the transferee is receiving and
holding the Common Stock or other securities subject to the provisions of this
Agreement, including without limitation this Section 1.12. If any Restricted
Person is released from any agreement similar to the agreements set forth in
this Section 1.12, or if the provisions of any such similar agreement are waived
with respect to any Restricted Person, then without any further act the
agreements set forth in this Section 1.12 shall terminate. The underwriters in
connection with the Company's initial public offering are intended third party
beneficiaries of this Section 1.12 and shall have the right, power and authority
to enforce the provisions hereof as though they were a party hereto.

In order to enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the Registrable Securities of each Holder (and the
shares or securities of every other person subject to the foregoing restriction)
until the end of such period.

          1.13 Termination of Registration Rights.

               No Holder shall be entitled to exercise any right provided for in
this Section 1 after five (5) years following a Qualified Public Offering or, as
to any Holder, such earlier time at which all Registrable Securities held by
such Holder (and any affiliate of the Holder with whom such Holder must
aggregate its sales under Rule 144) can be sold in any three (3)-month period
without

                                      12


registration in compliance with Rule 144 of the Act.

     2.   Covenants of the Company.

          2.1  Delivery of Financial Statements.

               The Company shall deliver to each Investor holding, together with
such Investor's Affiliates (as defined in Rule 405 under the Act), at least
250,000 shares of Registrable Securities (as adjusted for subsequent stock
dividends, splits or combinations):

                    (a)  as soon as practicable, but in any event within ninety
(90) days after the end of each fiscal year of the Company, an income statement
for such fiscal year, a balance sheet of the Company and statement of
shareholder's equity as of the end of such year, and a statement of cash flows
for such year, such year-end financial reports to be in reasonable detail,
prepared in accordance in generally accepted accounting principles ("GAAP"), and
audited and certified by independent public accountants of nationally recognized
standing selected by the Company;

                    (b)  as soon as practicable, but in any event within thirty
(30) days after the end of each of the first three (3) quarters of each fiscal
year of the Company, an unaudited income statement, statement of cash flows for
such fiscal quarter and an unaudited balance sheet as of the end of such fiscal
quarter;

                    (c)  within thirty (30) days of the end of each month, an
unaudited income statement and statement of cash flows and balance sheet for and
as of the end of such month, in reasonable detail; and

                    (d)  as soon as practicable, but in any event at least
thirty (30) days prior to the end of each fiscal year, a comprehensive operating
budget forecasting the Company's revenues, expenses and cash position on a
month-to-month basis for the upcoming fiscal year , prepared on a monthly basis,
including balance sheets, income statements and statements of cash flows for
such months and, as soon as prepared, any other budgets or revised budgets
prepared by the Company.

          2.2  Inspection.

               The Company shall permit each Investor holding, together with
such Investor's Affiliates (as defined in Rule 405 under the Act), at least
250,000 shares of Registrable Securities (as adjusted for stock dividends,
splits or combinations), at such Investor's expense, to visit and inspect the
Company's properties, to examine its books of account and records and to discuss
the Company's affairs, finances and accounts with its officers, all at such
reasonable times as may be requested by the Investor, provided, however, that
the Company shall not be obligated pursuant to this Section 2.2 to provide
access to any information that it reasonably considers to be a trade secret or
similar confidential information unless such Investor executes a nondisclosure
agreement in a form reasonably satisfactory to the Company.

          2.3  Termination of Information and Inspection Covenants.

               The covenants set forth in Sections 2.1 and 2.2 shall terminate
as to Investors and be of no further force or effect when the sale of securities
pursuant to a registration statement filed by the Company under the Act in
connection with the final commitment underwritten offering of its securities to
the general public is consummated or when the Company first becomes subject to
the periodic reporting requirements of Sections 12(g) or 15(d) of the 1934 Act,
whichever event shall

                                      13


first occur.

          2.4  Right of First Offer.

               Subject to the terms and conditions specified in this paragraph
2.4, the Company hereby grants to each Major Investor (as hereinafter defined) a
right of first offer with respect to future sales by the Company of its Shares
(as hereinafter defined). For purposes of this Section 2.4, a Major Investor
shall mean any Investor or transferee that holds, together with such Investor's
Affiliates (as defined in Rule 405 under the Act), at least 450,000 shares of
Preferred Stock (or the Common Stock issued upon conversion thereof) (as
adjusted for stock splits, stock dividends, combinations and other
recapitalizations). For purposes of this Section 2.4, Investor includes any
general partners, retired partners and affiliates of an Investor. A Major
Investor shall be entitled to apportion the right of first offer hereby granted
it among itself and its partners, retired partners and affiliates in such
proportion as it deems appropriate. Each time the Company proposes to offer any
shares of, or securities convertible into or exchangeable or exercisable for any
shares of, any class of its capital stock ("Shares"), the Company shall first
make an offering of such Shares to each Major Investor in accordance with the
following provisions:

          (a)  The Company shall deliver a notice in accordance with Section 3.5
("Notice") to the Major Investor, stating (i) its bona fide intention to offer
such Shares, (ii) the number of such Shares to be offered, and (iii) the price
and terms upon which it proposes to offer such Shares.

          (b)  By written notification received by the Company, within twenty
(20) calendar days after receipt of the Notice, the Major Investor may elect to
purchase or obtain, at the price and on the terms specified in the Notice, up to
that portion of such Shares that equals the proportion that the number of shares
of Common Stock issued and held, or issuable upon conversion of the Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D
Preferred Stock then held, by such Major Investor bears to the total number of
shares of Common Stock of the Company then outstanding (assuming full conversion
of all convertible securities). The Company shall promptly, in writing, inform
each Major Investor that elects to purchase all the Shares available to it (a
"Fully-Exercising Investor") of any other Major Investor's failure to do
likewise. During the ten (10) day period commencing after such information is
given, each Fully-Exercising Investor may elect to purchase that portion of the
Shares for which Major Investors were entitled to subscribe but which were not
subscribed for by the Major Investors that is equal to the proportion that the
number of shares of Common Stock issued and held, or issuable upon conversion of
Preferred Stock then held, by such Fully-Exercising Investor bears to the total
number of shares of Common Stock issued and held by all Fully-Exercising
Investors who wish to purchase some of the unsubscribed shares.

          (c)  If all Shares that Investors are entitled to obtain pursuant to
subsection 2.4(b) are not elected to be obtained as provided in subsection
2.4(b) hereof, the Company may, during the ninety (90) day period following the
expiration of the period provided in subsection 2.4(b) hereof, offer the
remaining unsubscribed portion of such Shares to any person or persons at a
price not less than, and upon terms no more favorable to the offeree than those
specified in the Notice. If the Company does not enter into an agreement for the
sale of the Shares within such period, or if such agreement is not consummated
within ninety (90) days of the execution thereof, the right provided hereunder
shall be deemed to be revived and such Shares shall not be offered unless first
reoffered to the Major Investors in accordance herewith.

          (d)  The right of first offer in this paragraph 2.4 shall not be
applicable to (i) the

                                      14


issuance of Common Stock as a result of stock splits, reverse stock splits or
stock dividends, (ii) Common Stock issuable pursuant to warrants, convertible
notes or other rights to acquire securities of the Corporation outstanding as of
the Purchase Date or issued upon the unanimous approval of the Board of
Directors, (iii) Common Stock issuable or issued to employees, consultants,
officers or directors of the Corporation under the Company's 1997 Option Plan,
(iv) Common Stock issued or issuable upon conversion of the Preferred Stock, (v)
fractional shares of Common Stock issued to certain of the existing holders of
Common Stock who hold fractional shares as of the date hereof, as approved by
the Board of Directors of the Company, (vi) the issuance of securities pursuant
to a bona fide, firmly underwritten public offering of shares of Common Stock,
registered under the Act or (vii) the issuance of securities in connection with
a bona fide strategic alliance or other partnership or business acquisition of
or by the Company, whether by merger, consolidation, sale of assets, sale or
exchange of stock or otherwise; subject to the approval of the Holders of a
majority of the Series C Preferred Stock and the Series D Preferred Stock voting
together, if in any case the number of shares issued pursuant to this clause
(vii) in any transaction or series of related transactions would exceed 20% of
the fully-diluted shares outstanding immediately prior to the first such
issuance.

          2.5  Board Expenses.

               The Company covenants to reimburse each non-employee director for
all reasonable travel-related expenses incurred in connection with his
attendance at meetings of the Board of Directors.

          2.6  Termination of Certain Covenants.

               The covenants set forth in Sections 2.4 and 2.5 shall terminate
and be of no further force or effect upon and in connection with a Qualified
Public Offering.

     3.   Rights of Refusal and Co-Sale.

          3.1  Rights of Refusal.

                    (a)  Transfer Notice. If at any time any Holder (a
                         ---------------
"Transferring Holder") proposes to sell, transfer or otherwise convey any
Registrable Securities to one or more third parties pursuant to an understanding
with such third parties (a "Transfer"), then such Transferring Holder shall give
the Company written notice of that Transferring Holder's intention to make the
Transfer (the "Transfer Notice"), which Transfer Notice shall include (i) a
description of the Registrable Securities to be transferred ("Offered Shares"),
(ii) the identity (including the name and address) of the prospective
transferee(s) and (iii) the consideration and the material terms and conditions
upon which the proposed Transfer is to be made. The Company will upon receipt
promptly forward the Transfer Notice to each Holder who, together with such
Holder's "Affiliates" (as defined in Rule 405 under the Act) holds more than
200,000 Registrable Securities (an "Offeree Holder"). The Transfer Notice shall
certify that the Transferring Holder has received a firm offer from the
prospective transferee(s) and in good faith believes a binding agreement for the
Transfer is obtainable on the terms set forth in the Transfer Notice. The
Transfer Notice shall also include a copy of any written proposal, term sheet or
letter of intent or other agreement relating to the proposed Transfer.

                    (b)  Company's Option. The Company shall have an option for
                         ----------------
a period of ten (10) days from receipt of the Transfer Notice to elect to
purchase all or any portion of the Offered Shares at the same price and subject
to the same material terms and conditions as described in the Transfer Notice.
The Company may exercise such purchase option and, thereby, purchase all (or a
portion of) the Offered Shares by notifying the Transferring Holder in writing

                                      15


before expiration of such (10) day period as to the number of such shares which
it wishes to purchase. If the Company gives the Transferring Holder notice that
it desires to purchase such shares, then payment for the Offered Shares shall be
by check, wire transfer, cancellation of indebtedness or any combination of the
foregoing, against delivery of the Offered Shares to be purchased at a place
agreed upon between the parties and at the time of the scheduled closing
therefor, which shall be no later than forty-five (45) days after the Company's
receipt of the Transfer Notice, unless the Transfer Notice contemplated a later
closing with the prospective third party transferee(s) or unless the value of
the purchase price has not yet been established pursuant to Section 3.1(e). If
the Company fails to purchase all of the Offered Shares by exercising the option
granted in this Section 3.1(b) within the period provided, the Offered Shares
shall be subject to the options granted to the Offeree Holders pursuant to this
Agreement.

                    (c)  Additional Transfer Notice. Subject to the Company's
                         --------------------------
right set forth in Section 3.1(b), if at any time the Transferring Holder
proposes a Transfer, and the Company has declined to purchase all of the Offered
Shares, the Transferring Holder shall give each Offeree Holder an "Additional
Transfer Notice" which shall include all of the information and certifications
required in a Transfer Notice and shall additionally identify the Offered Shares
which the Company has declined to purchase (the "Remaining Shares") and briefly
describe each Offeree Holders' rights of first refusal and co-sale rights with
respect to the proposed Transfer.

                    (d)  Holders' Option. The Offeree Holders shall have an
                         ---------------
option for a period of twenty (20) days from the Offeree Holder's receipt of the
Additional Transfer Notice from the Holder set forth in Section 3.1(c) to elect
to purchase their respective pro rata share of the Remaining Shares at the same
price and subject to the same material terms and conditions as described in the
Additional Transfer Notice. Each Offeree Holder may exercise such purchase
option and, thereby, purchase all or any portion of his, her or its pro rata
share (with any reallotments as provided below) of the Remaining Shares, by
notifying the Transferring Holder and the Company in writing, before expiration
of the twenty (20) day period as to the number of such shares which he, she or
it wishes to purchase (including any reallotment). Each Offeree Holder's pro
rata share of the Remaining Shares shall be a fraction of the Remaining Shares,
the numerator of which is equal to the number of shares of Common Stock
(including shares of Common Stock issuable upon conversion of Preferred Shares)
owned by such Offeree Holder on the date of the Transfer Notice and the
denominator of which is equal to the total number of shares of Common Stock
(including shares of Common Stock issuable upon conversion of Preferred Shares)
held by all Offeree Holders on the date of the Transfer Notice. Each Offeree
Holder shall have a right of reallotment such that, if any other Offeree Holder
fails to exercise the right to purchase its full pro rata share of the Remaining
Shares, the other participating Offeree Holders may exercise an additional right
to purchase, on a pro rata basis, the Remaining Shares not previously purchased.
Such reallotment shall occur within five (5) days after the expiration of the
twenty (20) day period described in this Section 3.1(d) applicable to the
initial allotment of the Remaining Shares. Each Offeree Holder shall be entitled
to apportion Remaining Shares to be purchased among its partners, retired
partners and affiliates, provided that such Offeree Holder notifies the
Transferring Holder of such allocation. If an Offeree Holder gives the
Transferring Holder notice that it desires to purchase its pro rata share of the
Remaining Shares and, as the case may be, its reallotment, then payment for the
Remaining Shares shall be by check, wire transfer, cancellation of indebtedness
or any combination of the foregoing, against delivery of the Remaining Shares to
be purchased at a place agreed upon between the parties and at the time of the
scheduled closing therefor, which shall be no later than forty-five (45) days
after the Offeree Holder's receipt of the Additional Transfer Notice, unless the
Transfer Notice contemplated a later closing with the prospective third party
transferee(s) or unless the value of the purchase price has not

                                      16


yet been established pursuant to Section 3.1(e).

          (e) Valuation of Property.  Should the purchase price specified in the
              ---------------------
Transfer Notice or Additional Transfer Notice be payable in property other than
cash or evidences of indebtedness, the Company (or the Offeree Holders) shall
have the right to pay the purchase price in the form provided in Sections 3(b)
and (d) equal in amount to the value of such property.  If the Transferring
Holder and the Company (or the Offeree Holders) cannot agree on such value
within ten (10) days after the Company's receipt of the Transfer Notice (or the
Holders' receipt of the Additional Transfer Notice), the valuation shall be made
by an appraiser of recognized standing selected by the Transferring Holder and
the Company (or the Offeree Holders) or, if they cannot agree on an appraiser
within twenty (20) days after the Company's receipt of the Transfer Notice (or
the Holders' receipt of the Additional Transfer Notice), each shall select an
appraiser of recognized standing and the two appraisers shall designate a third
appraiser of recognized standing, whose appraisal shall be determinative of such
value.  The cost of such appraisal shall be shared equally by the Transferring
Holder and the Company (or the Offeree Holders), with the half of the cost borne
by the Company and the Offeree Holders borne pro rata by each based on the
number of shares such parties were interested in purchasing pursuant to this
Section 3.  If the time for the closing of the Company's purchase or the Offeree
Holders' purchase has expired but for the determination of the value of the
purchase price offered the prospective transferee(s), then such closing shall be
held on or prior to the fifth business day after such valuation shall have been
made pursuant to this subsection.

          3.2  Right of Co-Sale.

               (a)  To the extent the Company and the Offeree Holders do not
exercise their respective rights of refusal as to all of the Offered Shares
pursuant to Section 3.1, then each Offeree Holder (a "Selling Holder," for
purposes of this subsection 3.2) which notifies the Transferring Holder in
writing within thirty (30) days after receipt of the Additional Transfer Notice,
shall have the right to participate in such sale of Registrable Securities on
the same terms and conditions as specified in the Transfer Notice. Such Selling
Holder's notice to the Transferring Holder shall indicate the number of shares
of Registrable Securities the Selling Holder wishes to sell under his, her or
its right to participate. To the extent one or more of the Selling Holders
exercise such right of participation in accordance with the terms and conditions
set forth below, the number of shares of Registrable Securities that the
Transferring Holder may sell in the Transfer shall be correspondingly reduced.

               (b)  Each Selling Holder may sell all or any part of that number
of shares of Registrable Securities equal to the product obtained by multiplying
(i) the aggregate number of shares of Registrable Securities covered by the
Transfer Notice by (ii) a fraction, the numerator of which is the number of
shares of Common Stock (including shares of Common Stock issuable upon
conversion of Preferred Shares) owned by the Selling Holder on the date of the
Transfer Notice and the denominator of which is the total number of shares of
Common Stock (including shares of Common Stock issuable upon conversion of
Preferred Shares) owned by the Transferring Holder and all of the Selling
Holders on the date of the Transfer Notice.

               (c)  Each Selling Holder shall effect its participation in the
sale by promptly delivering to the Transferring Holder for transfer to the
prospective purchaser one or more certificates, properly endorsed for transfer,
which represent:

                    (i) the type and number of shares of Registrable Securities
which such Selling Holder elects to sell; or

                                      17


                    (ii) that number of shares of Registrable Securities which
are at such time convertible into the number of shares of Common Stock which
such Selling Holder elects to sell; provided, however, that if the prospective
third-party purchaser objects to the delivery of Registrable Securities in lieu
of Common Stock, such Selling Holder shall convert such Registrable Securities
into Common Stock and deliver Common Stock as provided in this Section 3.2. The
Company agrees to make any such conversion concurrent with the actual transfer
of such shares to the transferee and contingent on such transfer.

               (d)  The stock certificate or certificates that the Selling
Holder delivers to the Transferring Holder pursuant to Section 3.2(c) shall be
transferred to the prospective transferee in consummation of the sale of the
Registrable Securities pursuant to the terms and conditions specified in the
Transfer Notice, and the Transferring Holder shall concurrently therewith remit
to such Selling Holder that portion of the sale proceeds to which such Selling
Holder is entitled by reason of its participation in such sale. To the extent
that any prospective transferee or transferees prohibit such assignment or
otherwise refuses to purchase shares or other securities from a Selling Holder
exercising its rights of co-sale hereunder, the Transferring Holder shall not
sell to such prospective purchaser any Registrable Securities unless and until,
simultaneously with such sale, the Transferring Holder shall purchase such
shares or other securities from such Selling Holder for the same consideration
and on the same terms and conditions as the proposed transfer described in the
Transfer Notice.

          3.3  Non-Exercise of Rights.

               To the extent that the Company and the Offeree Holders have not
exercised their rights to purchase all of the Offered Shares within the time
periods specified in Section 3.1, the Transferring Holder shall have a period of
thirty (30) days from the expiration date of such rights in which to sell the
Offered Shares not purchased by the Company or the Offeree Holders, upon terms
and conditions (including the purchase price) no more favorable than those
specified in the Transfer Notice to the third-party transferee(s) identified in
the Transfer Notice.  The third-party transferee(s) shall acquire such shares
subject to the rights of first refusal and co-sale rights under this Agreement.
In the event the Transferring Holder does not consummate the sale or disposition
of such shares within the thirty (30) day period following the expiration of
these rights, the Company's first refusal rights and the Offeree Holders' first
refusal rights and co-sale rights shall continue to be applicable to any
subsequent disposition of the Offered Shares by the Transferring Holder until
such right lapses in accordance with the terms of this Agreement.  Furthermore,
the exercise or non-exercise of the rights of the Company and the Offeree
Holders under this Section 3 to purchase Registrable Securities from the
Transferring Holder or participate in sales of Registrable Securities by the
Transferring Holder shall not adversely affect their rights to make subsequent
purchases from the Transferring Holder of Registrable Securities or subsequently
participate in sales of Registrable Securities by the Transferring Holder.

          3.4  Limitations to Rights of Refusal and Co-Sale.

               Notwithstanding the provisions of Section 3.1 and 3.2 of this
Agreement, (i) each Holder may sell or otherwise transfer, assign, with or
without consideration, Registrable Securities to a transferee or assignee of
such securities that is a direct or indirect partner, limited partner or retired
partner of a Holder (or a spouse, former spouse or member of such partner's,
limited partner's or retired partner's immediate family, or a custodian, trustee
(including a trustee of a voting trust), executor, or other fiduciary for the
account of such partner, limited partner or retired partner or his or her
spouse, former spouse or immediate family members) or an Affiliate (as defined

                                      18


in Rule 405 under the Act); and (ii) Larry Barels and Chris Logan may within
thirty (30) days of the date hereof transfer an aggregate of 300,000 Registrable
Securities to a transferee, provided that each such transferee or assignee,
prior to the completion of the sale, transfer, or assignment shall have executed
documents assuming the obligations of such Holder under this Agreement with
respect to the transferred securities. Such transferred Registrable Securities
shall remain "Registrable Securities" hereunder, and such transferee, assignee
or donee shall be treated as a "Holder" for purposes of this Agreement.

          3.5  Prohibited Transfers.

               (a)  In the event a Transferring Holder should sell any
Registrable Securities in contravention of the co-sale rights of the Selling
Holders under Section 3.2 (a "Prohibited Transfer"), the Selling Holders, in
addition to such other remedies as may be available at law, in equity or
hereunder, shall have the put option provided below, and such Transferring
Holder shall be bound by the applicable provisions of such option.

               (b)  In the event of a Prohibited Transfer by such Transferring
Holder, each Selling Holder shall have the right to sell to such Transferring
Holder the type and number of shares of Registrable Securities equal to the
number of shares each Selling Holder would have been entitled to transfer to the
third-party transferee(s) under Section 3.2 hereof had the Prohibited Transfer
been effected pursuant to and in compliance with the terms hereof. Such sale
shall be made on the following terms and conditions:

                    (i)   The price per share at which the shares are to be sold
to such Transferring Holder shall be equal to the price per share paid by the
third-party transferee(s) to the Transferring Holder in the Prohibited Transfer.
The Transferring Holder shall also reimburse each Selling Holder for any and all
fees and expenses, including legal fees and expenses, incurred pursuant to the
exercise or the attempted exercise of the Selling Holder's rights under Section
3.

                    (ii)  Within ninety (90) days after the later of the dates
on which the Transferring Holder (A) received notice of the Prohibited Transfer
or (B) otherwise became aware of the Prohibited Transfers each Selling Holder
shall, if exercising the option created hereby, deliver to the Transferring
Holder the certificate or certificates representing shares to be sold, each
certificate to be properly endorsed for transfer.

                    (iii) The Transferring Holder shall, upon receipt of the
certificate or certificates for the shares to be sold, pursuant to this Section
3.5, pay the aggregate purchase price therefor and the amount of reimbursable
fees and expenses, as specified in subparagraph 3.5(c)(i), in cash or by other
means acceptable to the Selling Holder.

                    (iv)  Notwithstanding the foregoing, any attempt by a
Transferring Holder to transfer Registrable Securities in violation of Section 3
hereof shall be void and the Company agrees it will not effect such a transfer
nor will it treat any alleged transferee(s) as the holder of such shares without
the written consent of a majority in interest of the Holders (on an as converted
basis).

               (c)  Any transfer made in contravention of the rights of first
refusal and co-sale under this Section 3 shall be null and void.

          3.6  Legend.

               Each existing or replacement certificate for shares now owned or
hereafter acquired by the Common Holders shall bear the following legend upon
its face:

                                      19


          "THE SALE, PLEDGE, HYPOTHECATION, ASSIGNMENT OR TRANSFER OF
          THE SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO
          THE TERMS AND CONDITIONS OF A CERTAIN INVESTOR RIGHTS
          AGREEMENT BY AND BETWEEN THE STOCKHOLDER, THE CORPORATION
          AND CERTAIN HOLDERS OF STOCK OF THE CORPORATION. COPIES OF
          SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE
          SECRETARY OF THE CORPORATION."

          3.7  Termination of Rights of Refusal and Co-Sale.

               The rights and remedies described under this Section 3 shall
terminate and be of no further force or effect upon the earlier to occur of: (i)
a Qualified Public Offering; and (ii) the closing of the Company's sale of all
or substantially all of its assets or the acquisition of the Company by another
entity by means of merger, consolidation or other transaction or series of
related transactions (including, without limitation, any reorganization, merger
or consolidation in which more than fifty percent (50%) of the outstanding
voting power of this corporation is disposed of (whether or not the stockholders
prior to such transaction are stockholders of the acquiring entity as of the
acquisition date), but excluding any merger effective exclusively for the
purpose of changing the domicile of the Corporation.
