            FIFTH AMENDED AND RESTATED INVESTORS' RIGHTS AGREEMENT
            ------------------------------------------------------

          THIS FIFTH AMENDED AND RESTATED INVESTORS' RIGHTS AGREEMENT (the
"Agreement") is made as of the 4th day of June 1998, by and among Agile Software
Corporation, a California corporation (the "Company") and the investors listed
on Schedule A hereto (the "Investors").

                                   RECITALS
                                   --------

          WHEREAS, certain of the Investors (the "Prior Investors") possess
registration rights, information rights, rights of first offer and other rights
pursuant to that certain Fourth Amended and Restated Investors' Rights
Agreement, dated as of November 14, 1998, among the Company and such Prior
Investors (the "Prior Agreement");

          WHEREAS, certain of the Investors (the "Series F Investors") are a
party to the Series F Preferred Stock Purchase Agreement of even date herewith
(the "Series F Agreement") between the Company and the Series F Investors,
pursuant to which the Series F Investors are purchasing shares of Series F
Preferred Stock of the Company;

          WHEREAS, in order to induce the Company to enter into the Series F
Agreement and to induce the Series F Investors to invest funds in the Company
pursuant to the Series F Agreement, the Prior Investors hereby agree to waive
their rights under the Prior Agreement, and the Investors and the Company hereby
agree that this Agreement shall govern the rights of the Investors to cause the
Company to register shares of Common Stock issued or issuable to such persons
and certain other matters as set forth herein;

          NOW, THEREFORE, in consideration of the promises, covenants and
conditions set forth herein, the parties hereto hereby agree as follows:

          1.   Registration Rights. The Company covenants and agrees as follows:
               -------------------

          1.1  Definitions. For purposes of this Section 1:
               -----------

          (a)  The term "Securities Act" means the Securities Act of 1933, as
amended.

          (b)  The term "Form S-3" means such form under the Securities Act as
in effect on the date hereof or any registration form under the Securities Act
subsequently adopted by the SEC that permits inclusion or incorporation of
substantial information by reference to other documents filed by the Company
with the SEC.

          (c)  The term "Holder" means any person owning or having the right to
acquire Registrable Securities or any assignee thereof in accordance with
Section 1.13 hereof.


          (d)  The term "Exchange Act" shall mean the Securities Exchange Act of
1934, as amended.

          (e)  The terms "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, and the declaration or
ordering of effectiveness of such registration statement or document.

          (f)  The term "Registrable Securities" means (i) the Common Stock
issuable or issued upon conversion of the Series A Preferred Stock, (ii) the
Common Stock issuable or issued upon conversion of the Series B Preferred Stock,
(iii) the Common Stock issuable or issued upon conversion of the Series C
Preferred Stock, (iv) the Common Stock issuable or issued upon conversion of the
Series D Preferred Stock, (v) the Common Stock issuable or issued upon
conversion of the Series E Preferred Stock, (vi) the Common Stock issuable or
issued upon conversion of the Series F Preferred Stock, (vii) any shares of
Common Stock issuable or issued upon the conversion of the Preferred Stock
issued upon conversion of the Series C, Series D, Series E, Series F or any
successive series of Preferred Stock and (viii) any Common Stock of the Company
issued as (or issuable upon the conversion or exercise of any warrant, right or
other security which is issued as) a dividend or other distribution with respect
to, or in exchange for or in replacement of the shares referenced in (i), (ii),
(iii), (iv), (v), (vi) and (vii) above, excluding in all cases, however, any
Registrable Securities sold by a person in a transaction in which his or her
rights under this Section 1 are not properly assigned as provided herein;
provided, however, that Common Stock and other securities shall only be treated
as Registrable Securities if and so long as (A) they have not been sold to or
through a broker or dealer or underwriter in a public distribution or a public
securities transaction and (B) the registration rights associated with such
securities have not been terminated pursuant to Section 1.16 hereof.

          (g)  The number of shares of "Registrable Securities then outstanding"
shall be determined by the number of shares of Common Stock outstanding which
are, and the number of shares of Common Stock issuable pursuant to then
exercisable or convertible securities which are, Registrable Securities.

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

          1.2  Request for Registration.
               ------------------------

          (a)  If the Company shall receive at any time after the earlier of (i)
June 2, 1999 or (ii) three months after the effective date of the first
registration statement for a public offering of securities of the Company (other
than a registration statement relating either to the sale of securities to
employees of the Company pursuant to a stock option, stock purchase or similar
plan or a SEC Rule 145 transaction) a written request from the Holders of at
least 30% of the Registrable Securities then outstanding that the Company file a
registration statement under the Securities Act covering the registration of at
least 30% of the Registrable Securities then outstanding (or a lesser percent if
the anticipated aggregate offering price, net of underwriting discounts and
commissions, would exceed $10,000,000), then the Company shall:

                                      2.


                    (i)  within ten days of the receipt thereof, give written
notice of such request to all Holders; and

                    (ii) effect as soon as practicable, and in any event within
60 days of the receipt of such request, the registration under the Securities
Act of all Registrable Securities which the Holders request to be registered,
subject to the limitations of subsection 1.2(b), within 20 days of the mailing
of such notice by the Company in accordance with Section 3.5.

          (b)  If the Holders initiating the registration request hereunder (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 subsection 1.2(a) and the Company shall
include such information in the written notice referred to in subsection 1.2(a).
The underwriter will be selected by the Company and shall be reasonably
acceptable to a majority in interest of the Initiating Holders. In such event,
the right of any Holder to include his or her 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 to 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
(together with the Company as provided in subsection 1.4(e)) enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting. Notwithstanding any other provision of this
Section 1.2, if the underwriter advises the Initiating Holders in writing that
marketing factors require a limitation of the number of shares to be
underwritten, then the Initiating Holders shall so advise all Holders of
Registrable Securities which would otherwise be underwritten pursuant hereto,
and the number of shares of Registrable Securities that may be included in the
underwriting shall be allocated among all Holders thereof, including the
Initiating Holders, in proportion (as nearly as practicable) to the amount of
Registrable Securities of the Company owned by each Holder; 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 first entirely
excluded from the underwriting.

          (c)  Notwithstanding the foregoing, if the Company shall furnish to
the Holders requesting a registration statement pursuant to this Section 1.2 a
certificate signed by the Chief Executive Officer of the Company stating that,
in the good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its shareholders for such registration
statement to be filed and it is therefore essential to defer the filing of such
registration statement, the Company shall have the right to defer taking action
with respect to such filing for a period of not more than 120 days after receipt
of the request of the Initiating Holders; provided, however, that the Company
may not utilize this right more than once in any 12-month period.

          (d)  In addition, the Company shall not be obligated to effect, or to
take any action to effect, any registration pursuant to this Section 1.2:

                                      3.


                    (i)  after the Company has effected two registrations
pursuant to this Section 1.2 and such registrations have been declared or
ordered effective;

                   (ii)  during the period starting with the date 60 days prior
to the Company's good faith estimate of the date of filing of, and ending on a
date 180 days after the effective date of, a registration subject to Section 1.3
hereof; provided that the Company is actively employing in good faith all
reasonable efforts to cause such registration statement to become effective; or

                  (iii)  if the Initiating Holders propose to dispose of shares
of Registrable Securities that may be immediately registered on Form S-3
pursuant to a request made pursuant to Section 1.12 below.

          1.3  Company Registration. 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 Securities 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, 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 or a registration in which the
only Common Stock being registered is Common Stock issuable upon conversion of
debt securities which are also being registered), the Company shall, at such
time, promptly give each Holder written notice of such registration. Upon the
written request of each Holder given within 20 days after mailing of such notice
by the Company in accordance with Section 3.5, the Company shall, subject to the
provisions of Section 1.8, cause to be registered under the Securities Act all
of the Registrable Securities that each such Holder has requested to be
registered.

          1.4  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 its best 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 120 days or 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
Securities Act with respect to the disposition of all securities covered by such
registration statement.

                                      4.


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

          (d)  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 shall be reasonably requested by the Holders;
provided that the Company shall 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 unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Securities 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. Each Holder participating
in such underwriting shall also enter into and perform its obligations under
such an agreement.

          (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 Securities Act of 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 or other trading market 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.

          (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, 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 as of
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.

                                      5.


          1.5  Furnish Information.
               --------------------

          (a)  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.

          (b)  The Company shall have no obligation with respect to any
registration requested pursuant to Section 1.2 or Section 1.12 if, due to the
operation of subsection 1.5(a), the number of shares or the anticipated
aggregate offering price of the Registrable Securities to be included in the
registration does not equal or exceed the number of shares or the anticipated
aggregate offering price required to originally trigger the Company's obligation
to initiate such registration as specified in subsection 1.2(a) or subsection
1.12(b)(2), whichever is applicable.

          1.6  Expenses of Demand Registration. All expenses other than
               -------------------------------
underwriting discounts and commissions incurred in connection with
registrations, filings or qualifications pursuant to Section 1.2, including
(without limitation) all registration, filing and qualification fees, printers'
and accounting fees, reasonable fees and disbursements of counsel for the
Company (including fees and disbursements of counsel for the Company in its
capacity as counsel to the selling Holders hereunder; if Company counsel does
not make itself available for this purpose, the Company will pay the reasonable
fees and disbursements of one counsel for the selling Holders) shall be borne by
the Company; provided, however, that the Company shall not be required to pay
for any expenses of any registration proceeding begun pursuant to Section 1.2 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), unless the Holders of a
majority of the Registrable Securities agree to forfeit their right to one
demand registration pursuant to Section 1.2.

          1.7  Expenses of Company Registration. The Company shall bear and pay
               --------------------------------
all expenses incurred in connection with any registration, filing or
qualification of Registrable Securities with respect to registrations pursuant
to Section 1.3 for each Holder (which right may be assigned as provided in
Section 1.13), including (without limitation) all registration, filing and
qualification fees, printers' and accounting fees relating or apportionable
thereto and the reasonable fees and disbursements of counsel for the Company in
its capacity as counsel to the selling Holders hereunder (if Company counsel
does not make itself available for this purpose, the Company will pay the
reasonable fees and disbursements of one counsel for the selling Holders
selected by them), but excluding underwriting discounts and commissions relating
to Registrable Securities.

          1.8  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 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 then only in such
quantity as the underwriters determine in their sole discretion will not
jeopardize the success of the offering by

                                      6.


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 securities, including Registrable Securities, which 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 shareholders according to the total amount of securities entitled to be
included therein owned by each selling shareholder or in such other proportions
as shall mutually be agreed to by such selling shareholders) but in no event
shall (i) the amount of securities of the selling Holders included in the
offering be reduced below 20% 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 shareholders may be entirely excluded if
the underwriters make the determination described above and 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. For
purposes of the preceding parenthetical concerning apportionment, for any
selling shareholder which is a holder of Registrable Securities and which 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 shareholder," and any pro-rata reduction with
respect to such "selling shareholder" shall be based upon the aggregate amount
of shares carrying registration rights owned by all entities and individuals
included in such "selling shareholder," as defined in this sentence.

          1.9  Delay of Registration. No Holder shall have any right to obtain
               ---------------------
or seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 1.

          1.10 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, any underwriter (as defined in the Securities Act)
for such Holder and each person, if any, who controls such Holder or underwriter
within the meaning of the Securities Act or the Exchange Act, against any
losses, claims, damages or liabilities (joint or several) to which they may
become subject under the Securities Act, the Exchange Act or other federal or
state 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 Securities Act, the Exchange Act, any
state securities law or any rule or regulation promulgated under the Securities
Act, the Exchange Act or any state securities law; and the Company will pay to
each such Holder, underwriter or controlling person, as incurred, any legal or
other expenses

                                      7.


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 1.10(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 which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by any such Holder, 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 Securities Act, 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 Securities Act, the Exchange Act or other federal
or state law, 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, as incurred, any legal or other expenses reasonably incurred by any
person intended to be indemnified pursuant to this subsection 1.10(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 1.10(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, however, that in no event shall any indemnity under this
subsection 1.10(b) exceed the gross proceeds from the offering received by such
Holder.

          (c) Promptly after receipt by an indemnified party under this Section
1.10 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 1.10, 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 which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. 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
1.10, but the omission so to deliver written notice to the indemnifying party
will not

                                      8.


relieve it of any liability that it may have to any indemnified party otherwise
than under this Section 1.10.

          (d)  If the indemnification provided for in this Section 1.10 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 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. 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
1.10 shall survive the completion of any offering of Registrable Securities in a
registration statement under this Section 1 and otherwise.

          1.11 Reports Under Securities Exchange Act of 1934. With a view to
               ---------------------------------------------
making available to the Holders the benefits of Rule 144 promulgated under the
Securities 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 90 days after the
effective date of the first registration statement filed by the Company for the
offering of its securities to the general public;

          (b)  file with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act;
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 (at any time
after 90 days after the effective date of the first registration statement filed
by the Company), the Securities Act and the Exchange 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) a copy of the most recent annual or quarterly
report of the Company and such

                                      9.


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.

          1.12 Form S-3 Registration. In case the Company shall receive from any
               ---------------------
Holder or Holders 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 will:

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

          (b)  as soon as practicable, effect 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 Holder's or
Holders' Registrable Securities as are specified in such request, together with
all or such portion of the Registrable Securities of any other Holder or Holders
joining in such request as are specified in a written request given within 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 1.12: (1) if Form S-3 is
not available for such offering by the Holders; (2) 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 (net of any
underwriters' discounts or commissions) of less than $500,000; (3) if the
Company shall furnish to the Holders a certificate signed by the President 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 90 days after receipt of
the request of the Holder or Holders under this Section 1.12; provided, however,
that the Company shall not utilize this right more than once in any 12 month
period; (4) if the Company has, within the 12 month period preceding the date of
such request, already effected two registrations on Form S-3 for the Holders
pursuant to this Section 1.12; or (5) 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.

          (c)  Subject to 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. All expenses incurred in connection with a registration
requested pursuant to Section 1.12, including (without limitation) all
registration, filing and qualification fees, printers' and accounting fees and
the reasonable fees and disbursements of counsel for the selling Holder or
Holders and counsel for the Company, shall be borne pro rata by the Holder or
Holders participating in the Form S-3 Registration. Registrations effected
pursuant to this Section 1.12 shall not be counted as demands for registration
or registrations effected pursuant to Sections 1.2 or 1.3, respectively.

                                      10.


          1.13 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 who acquires all of the Registrable Securities
previously held by such Holder, or who, after such assignment or transfer, holds
at least 100,000 shares of Registrable Securities (subject to appropriate
adjustment for stock splits, stock dividends, combinations and other
recapitalizations), provided that: (a) the Company is, within 20 days after such
transfer, furnished with 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 1.15 below;
and (c) such assignment shall be effective only if immediately following such
transfer the further disposition of such securities by the transferee or
assignee is restricted under the Securities Act. For the purposes of determining
the number of shares of Registrable Securities held by a transferee or assignee,
the holdings of transferees and assignees of a partnership who are partners or
retired partners of such partnership (including spouses and ancestors, lineal
descendants and siblings of such partners or spouses who acquire Registrable
Securities by gift, will or intestate succession) shall be aggregated together
and with the partnership; provided that all assignees and transferees who would
not qualify individually for assignment of registration rights shall have a
single attorney-in-fact for the purpose of exercising any rights, receiving
notices or taking any action under this Section 1.

          1.14 Limitations on Subsequent Registration Rights. From and after the
               ---------------------------------------------
date of this Agreement, the Company shall not, without the prior written consent
of the Holders of a majority of the outstanding Registrable Securities, enter
into any agreement with any holder or prospective holder of any securities of
the Company which would allow such holder or prospective holder (a) to include
such securities in any registration filed under Section 1.2 or Section 1.3
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 his or her securities will not reduce the amount of the
Registrable Securities of the Holders which is included or (b) to make a demand
registration which could result in such registration statement being declared
effective prior to the earlier of either of the dates set forth in subsection
1.2(a) or within 120 days of the effective date of any registration effected
pursuant to Section 1.2.

          1.15 "Market Stand-Off" Agreement. Each Investor hereby agrees that,
               ----------------------------
during the period of duration specified by the Company and an underwriter of
Common Stock or other securities of the Company, following the effective date of
a registration statement of the Company filed under the Securities Act, it shall
not, to the extent requested by the Company and such underwriter, directly or
indirectly sell, offer to sell, contract to sell (including, without limitation,
any short sale), grant any option to purchase or otherwise transfer or dispose
of (other than to donees who agree to be similarly bound) any securities of the
Company held by it at any time during such period except Common Stock included
in such registration; provided, however, that:

          (a)  such agreement shall be applicable only to the first such
registration statement of the Company which covers Common Stock (or other
securities) to be sold on its behalf to the public in an underwritten offering;

                                      11.


          (b)  all officers and directors of the Company and all other persons
with registration rights (whether or not pursuant to this Agreement) enter into
similar agreements;

          (c)  such market stand-off time period shall not exceed 180 days; and

          (d)  such market stand-off shall not apply to securities purchased in
an underwritten public offering or in the open market following the Company's
initial public offering.

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

          Notwithstanding the foregoing, the obligations described in this
Section 1.15 shall not apply to a registration relating solely to employee
benefit plans on Form S-1 or Form S-8 or similar forms which may be promulgated
in the future, or to a registration relating solely to a Commission Rule 145
transaction on Form S-14 or Form S-15 or similar forms which may be promulgated
in the future.

          1.16 Termination of Registration Rights.
               ----------------------------------

          (a)  No Holder shall be entitled to exercise any right provided for in
this Section 1 after three years following the consummation of the sale of
securities pursuant to a registration statement filed by the Company under the
Securities Act in connection with the initial firm commitment underwritten
offering of its securities to the general public.

          (b)  In addition, the right of any Holder to request registration
pursuant to Section 1.2 or inclusion in any registration pursuant to Section 1.3
shall terminate on the closing of the first Company-initiated registered public
offering of Common Stock of the Company if all shares of Registrable Securities
held or entitled to be held upon conversion by such Holder may immediately be
sold under Rule 144 during any 90-day period, or on such date after the closing
of the first Company-initiated registered public offering of Common Stock of the
Company as all shares of Registrable Securities held or entitled to be held upon
conversion by such Holder may immediately be sold under Rule 144 during any 90-
day period; provided, however, that the provisions of this Section 1.16(b) shall
not apply to any Holder who owns more than 2% of the Company's outstanding stock
until such time as such Holder owns less than 2% of the outstanding stock of the
Company.

          2.   Covenants of the Company.
               ------------------------

          2.1  Delivery of Financial Statements. The Company shall deliver to

unaudited profit or loss statement, schedule as to the sources and application
of funds for such fiscal quarter and an unaudited balance sheet as of the end of
such fiscal quarter;

          (c)  (i) so long as such Investor holds at least 100,000 shares of

upon conversion thereof, and as adjusted for subsequent stock splits,
recombinations, reclassifications or the like), within 30 days of the end of
each month, an unaudited income statement and schedule as to the sources and
application of funds and balance sheet for and as of the end of such month, in
reasonable detail, and (ii) so long as such Investor holds at least 250,000

issued upon conversion thereof, and as adjusted for subsequent stock splits,
recombinations, reclassifications or the like), upon request, Board of
Directors' packages;

          (d)  the financial statements called for in subsections (b) and (c) of
this Section 2.1 shall be prepared in accordance with GAAP consistently applied
with prior practice for earlier periods (with the exception of footnotes that
may be required by GAAP) and shall fairly present the financial condition of the
Company and its results of operations for the period specified, subject to year-
end audit adjustment; and

          (e)  such other information relating to the financial condition,
business, prospects or corporate affairs of the Company as such Investor or any
assignee of such Investor may from time to time request, provided, however, that
the Company shall not be obligated under this subsection (e) or any other
subsection of Section 2.1 to provide information which it deems in good faith to
be a trade secret or similar confidential information.

          (f)  Each Investor agrees that information obtained by such Investor
pursuant to this Section 2.1 that is or would reasonably be perceived to be
proprietary to the Company will not be disclosed by such Investor without the
prior written consent of the Company.

          2.2  Inspection. The Company shall permit each Investor, 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 such Investor; provided, however, that the Company shall not be obligated
pursuant to this Section 2.2 to provide access to any information which it
reasonably considers to be a trade secret or similar confidential information.

          2.3  Termination of Information and Inspection Covenants. The
               ---------------------------------------------------
covenants set forth in Sections 2.1 and 2.2 shall terminate as to the Investors
and be of no further force or effect when the first sale of securities pursuant
to a registration statement filed by the Company

                                      13.


under the Securities Act in connection with the firm 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 Exchange Act, whichever event shall first occur.

          2.4  Right of First Offer. Subject to the terms and conditions
               --------------------
specified in this Section 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 (i) any Investor who holds at least 100,000
shares of the original investment such Investor made or makes in the Company
pursuant to the Series A Preferred Stock Purchase Agreement dated April 7, 1995
(the "Series A Agreement"), the Series B Preferred Stock Purchase Agreement
dated June 2, 1995 (the "Series B Agreement"), the Series C Preferred Stock
Purchase Agreement dated January 16, 1996 (the "Series C Agreement"), the Series
D Preferred Stock Purchase Agreement dated February 6, 1997 (the "Series D
Agreement"), the Series E Preferred Stock Purchase Agreement dated November 14,
1997 (the "Series E Agreement") or the Series F Agreement and (ii) any person
who acquires at least 100,000 shares of the Series A Preferred Stock (or the
Common Stock issued upon conversion thereof), the Series B Preferred Stock (or
the Common Stock issued upon conversion thereof), the Series C Preferred Stock
(or the Common Stock issued upon conversion thereof), the Series D Preferred
Stock (or the Common Stock issued upon conversion thereof), the Series E
Preferred Stock (or the Common Stock issued upon conversion thereof) or the
Series F Preferred Stock (or the Common Stock issued upon conversion thereof)
issued pursuant to the Series A Agreement, the Series B Agreement, the Series C
Agreement, the Series D Agreement, the Series E Agreement or the Series F
Agreement, as applicable. For purposes of this Section 2.4, an Investor includes
any general partners and affiliates of an Investor. An Investor shall be
entitled to apportion the right of first offer hereby granted it among itself
and its partners and affiliates in such proportions as it deems appropriate.

          Each time the Company proposes to offer any shares of, or securities
convertible into or exercisable for any shares of, any class of its capital
stock (the "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 (the "Notice") to the Major
Investors 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, if any, upon
which it proposes to offer such Shares.

          (b)  By written notification received by the Company, within 20
calendar days after giving of the Notice, each 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 which equals the proportion that the number of
shares of Common Stock issued and held, or issuable upon conversion of the
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 which decides to purchase all the shares available to it
(the "Fully-Exercising Investor") of any other Major Investor's failure to do
likewise. During the ten-day period commencing after such

                                      14.


information is given, each Fully-Exercising Investor shall be entitled to obtain
that portion of the Shares for which Major Investors were entitled to subscribe
but which were not subscribed for by the Major Investors which is equal to the
proportion that the number of shares of Common Stock issued and held, or
issuable upon conversion of the Preferred Stock then held, by such Fully-
Exercising Investor bears to the total number of shares of Common Stock issued
and held, or issuable upon conversion of the Preferred Stock then held, by all
Fully-Exercising Investors who wish to purchase some of the unsubscribed shares.

          (c)  With respect to Shares referred to in the Notice that are not
elected to be obtained as provided in subsection 2.4(b) hereof, the Company may,
during the 30-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 30 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 Section 2.4 shall not be
applicable (i) to the issuance or sale of shares of Common Stock (or options
therefor) to consultants, directors, officers, advisors or employees for the
primary purpose of soliciting or retaining their employment, (ii) to or after
consummation of a bona fide, firmly underwritten public offering of shares of
Common Stock registered under the Securities Act pursuant to a registration
statement filed on Form S-1 which results in gross cash proceeds to the Company
in excess of $20,000,000 and a public offering price of not less than $8.78 per
share (as adjusted for any subsequent stock dividends, stock splits,
recapitalizations or the like), (iii) to the issuance of securities pursuant to
the conversion or exercise of convertible or exercisable securities, (iv) to the
issuance of securities in connection with a bona fide business acquisition of or
by the Company, whether by merger, consolidation, sale of assets, sale or
exchange of stock or otherwise, (v) to the issuance of stock, warrants or other
securities or rights to persons or entities with which the Company has business
relationships or (vi) to the sale and issuance of the Series F Preferred Stock.

          (e)  The right of first offer set forth in this Section 2.4 may not be
assigned or transferred, except that (i) such right is assignable by each Holder
to any wholly owned subsidiary or parent of, or to any corporation or entity
that is, within the meaning of the Securities Act, controlling, controlled by or
under common control with any such Holder and (ii) such right is assignable
between and among any of the Holders.

          3.   Miscellaneous.
