SECTION 2
  RESTRICTIONS ON TRANSFERABILITY OF SECURITIES;
  COMPLIANCE WITH SECURITIES ACT    
  

        2.1    Restrictions on Transferability.    The Preferred Stock and the Conversion Shares shall not be transferable
except upon the conditions specified in this Section 2, which conditions are intended to ensure compliance with the provisions of the Securities Act, or, in the case of Section 2.14
hereof, to assist in an orderly distribution. Each Investor will cause any proposed transferee of the Preferred Stock and the Conversion Shares held by such Investor to agree to take and hold such
securities subject to the provisions and upon the conditions specified in this Agreement (including the "market stand-off" provisions of Section 2.14). 

        2.2    Restrictive Legend.    Each certificate representing (i) the Preferred Stock, (ii) Conversion
Shares and (iii) any other securities issued in respect of the Preferred Stock or Conversion Shares or Common Stock issuable upon any stock split, stock combination, stock dividend,
recapitalization, consolidation or similar event, shall (unless otherwise permitted by the provisions of this Agreement) be stamped or otherwise imprinted with a legend in substantially the following
form (in addition to any legend required under applicable state securities laws): 

THE
SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. SUCH SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF
SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT. COPIES OF THE AGREEMENT COVERING THE PURCHASE OF THESE SHARES AND RESTRICTING THEIR TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST
MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE COMPANY AT THE PRINCIPAL EXECUTIVE OFFICE. 

        2.3    Notice of Proposed Transfers.    The holder of each certificate representing Restricted Securities agrees to
comply in all respects with the provisions of this Section 2.3. Prior to any proposed transfer of any Restricted Securities (unless there is in effect a registration statement under the
Securities Act covering the proposed transfer), the holder thereof shall give written notice to the Company of such holder's intention to effect such transfer. Each such notice shall describe the
manner and circumstances of the proposed transfer in sufficient detail, and (except in transactions in compliance with Rule 144) shall be accompanied by either (i) a written opinion of
legal counsel, which counsel shall be reasonably satisfactory to the Company, addressed to the Company and reasonably satisfactory in form and substance to the Company's counsel, to the effect that
the proposed transfer of the Restricted Securities may be effected without registration under the Securities Act, or (ii) a "no action" letter 

from the Commission to the effect that the transfer of such securities without registration will not result in a recommendation by the staff of the Commission that action be taken with respect
thereto, whereupon the holder of such Restricted Securities shall be entitled to transfer such Restricted Securities in accordance with the terms of the notice delivered by the holder to the Company.
Except where the Restricted Securities are sold in compliance with Rule 144, each certificate evidencing the Restricted Securities transferred pursuant to the above shall bear the legend set
forth in Section 2.2 above, except that such certificate shall not bear such restrictive legend if, in the opinion of counsel for the Company, such legend is not required in order to establish
compliance with any provisions of the Securities Act. 

        2.4    Requested Registration.    

        (a)    Request for S-1 Registration.    In case the Company shall receive from Initiating Holders a
written request that the Company effect a registration, anticipated to have an aggregate public offering price of at least $5 million pursuant to a Registration Statement on a
Form S-1, the Company will: 

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

        (ii)  use
reasonable efforts to effect such registration, qualification or compliance as soon as practicable, but in no event later than 60 days after the date of such
request, (including, without limitation, appropriate qualification under applicable blue sky or other state securities laws and appropriate compliance with applicable regulations issued under the
Securities Act and any other governmental requirements or regulations) as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Registrable
Securities as are specified in such request together with all or such portion of the Registrable Securities of any Holder or Holders joining in the request as are specified in a written request
received by the Company within 15 days after receipt of such written notice from the Company; provided, that the Company shall not be obligated to take any action to effect any such
registration, qualification or compliance pursuant to this Section 2.4: 

        (A)  In
any particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting such registration, qualification or
compliance unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act; 

        (B)  Prior
to the earlier of (a) six months following the effective date of the Company's first registered offering to the general public of its securities for its own
account and (b) the fifth anniversary of the date of this Agreement; 

        (C)  After
the Company has effected two such registration pursuant to this Section 2.4(a), and such registrations have been declared or ordered effective and, except
as otherwise provided in this Agreement, pursuant to which at least some of the Registrable Securities specified in the written notice have been sold; 

        (D)  During
the period starting with the date 30 days prior to the Company's estimated date of filing of, and ending on the date three months immediately following the
effective date of, any registration statement pertaining to securities of the Company (other than a registration of securities with respect to an employee benefit plan), provided that the Company is
actively employing in good faith all reasonable efforts to cause such registration statement to become effective and provided further that in the case of a registration of securities in a
Rule 145 transaction such period shall end on the date such transaction is consummated; or 

        (E)  If
the Company shall furnish to such Holders a certificate signed by the President of the Company stating that in the good faith judgment of the Board of Directors it
would be seriously detrimental to the Company or its shareholders for a 

registration statement to be filed in the near future, then the Company's obligation to use all reasonable efforts to register, qualify or comply under this Section 2.4 shall be deferred for a
period not to exceed 120 days from the date of receipt of written request from the Initiating Holders; provided, however, that the Company may not utilize this right more than once in any
12 month period. 

        Subject
to the foregoing clauses (A) through (E), the Company shall file a registration statement covering the Registrable Securities so requested pursuant to this
Section 2.4(a) as soon as practicable after receipt of the request or requests from Initiating Holders. 

        (b)    Underwriting.    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 part of their request made pursuant to Section 2.4 and the Company shall include such information in the written notice
referred to in Section 2.4(a)(i). The right of any Holder to registration pursuant to Section 2.4 shall be conditioned upon such Holder's participation in such underwriting, and the
inclusion of such Holder's Registrable Securities in the underwriting shall be limited to the extent provided herein. 

        The
Company shall (together with all Holders proposing to distribute their Registrable Securities through such underwriting) enter into an underwriting agreement in customary form with
the representative of the underwriter or underwriters selected for such underwriting by the Initiating Holders. Notwithstanding any other provision of this Section 2.4, if the underwriters
advise the Initiating Holders in writing that marketing factors require a limitation of the number of shares to be underwritten, the Initiating Holders shall so advise all holders of Registrable
Securities, and the underwriter may limit the number of Registrable Securities to be included in the registration and underwriting on a pro rata basis
based on the total number of Registrable Securities held by the Holders. The Company and/or the underwriters may, in their sole discretion, round the number of securities offered hereunder to the
nearest 100 shares. No securities excluded from the underwriting by reason of the underwriter's marketing limitation shall be included in such registration. 

        If
any Holder of Registrable Securities disapproves of the terms of the underwriting, such person may elect to withdraw therefrom by written notice to the Company, the underwriters and
the Initiating Holders. The Registrable Securities so withdrawn shall also be withdrawn from registration; provided, however, that, if by the withdrawal of such Registrable Securities a greater number
of Registrable Securities held by other participating Holders may be included in such registration (up to the maximum of any limitation imposed by the underwriters), then the Company shall allocate
such greater number of Registrable Securities to such Holders in proportion, as nearly as practicable, to the respective amount of Registrable Securities held by such participating Holders. 

        If
the underwriter has not limited the number of Registrable Securities to be underwritten, the Company may include securities for its own account or for the account of other
shareholders of the Company in such registration if the underwriter so agrees. 

        2.5    Company Registration.    

        (a)    Registration.    If at any time or from time to time, the Company shall determine to register any of its
securities for its own account, other than (i) a registration on Form S-8 (or a similar or successor form) relating solely to employee stock option, stock purchase or other
benefit plans, or (ii) a registration on Form S-4 (or similar or successor form) relating solely to a Commission Rule 145 transaction, the Company will: 

          (i)  promptly
give to each Holder and Founder and Baby-C Holder written notice thereof; and 

        (ii)  offer
to include in such registration (and any related qualification under blue sky laws or other compliance), and in any underwriting involved therein, all the
Registrable Securities, Founders' Stock and Baby-C Stock specified in a written request or requests, made within 15 days after mailing of written notice by the Company, by any
Holder, Founder or Baby-C Holder except as set forth in Section 2.5(b) below. 

        (b)    Underwriting.    If the registration of which the Company gives notice is for a registered public offering
involving an underwriting, the Company shall so advise the Holders, Founders and Baby-C Holders as a part of the written notice given pursuant to Section 2.5(a)(i). In such event
the right of any Holder or Founder to registration pursuant to Section 2.5 shall be conditioned upon such Holder's, Founder's or Baby-C Holder's participation in such underwriting
and the inclusion of such Registrable Securities, Founders' Stock or Baby-C Stock in the underwriting to the extent provided herein. 

        All
Holders, Founders or Baby-C Holders proposing to distribute their securities through such underwriting shall (together with the Company and the other holders distributing
their securities through such underwriting) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company. Notwithstanding
any other provision of this Section 2.5, if the managing underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the underwriter may limit
the number of Registrable Securities, Founders' Stock and Baby-C Stock to be included in the registration and underwriting as follows: (i) in the event of the Company's initial
public offering then up to all of the Registrable Securities, Founders' Stock and Baby-C Stock may be excluded; (ii) the first shares in any registration and underwriting to be
excluded shall be the Founders' Stock and Baby-C Stock and the Registrable Securities shall be excluded only if no shares of Founders' Stock or Baby-C Stock are to be included
in the registration and underwriting and thereafter the Registrable Securities to be included in the registration and underwriting shall be allocated to the participating Holders on a  pro rata basis
based on the total number of Registrable Securities entitled to registration pursuant to registration rights granted by the Company to
the participating Holders; and (iii) if such offering is not the Company's initial public offering, then no such reduction may reduce the number of securities being sold by the Holders, the
Founders and Baby-C Holders to less than 25% of the shares being sold in
such offering. The number of securities includable by any Holder, Founder, Baby-C Holder or other person may, in the discretion of the underwriters, be rounded to the nearest one hundred
shares. No securities excluded from the underwriting by reason of the underwriter's marketing limitation shall be included in such registration. If some but not all Founders' Stock and
Baby-C Stock is to be excluded from a registration, the Founders' Stock and Baby-C Stock to be included shall be allocated to participating Founders and Baby-C
Holders on a pro rata basis based on the total number shares of Founders Stock and Baby-C Stock held. 

        If
any Holder, Founder or Baby-C Holder disapproves of the terms of any such underwriting, he may elect to withdraw therefrom by written notice to the Company and the
underwriter. Any securities excluded or withdrawn from such underwriting shall be withdrawn from such registration. 

        If
the underwriter has not limited the number of such shares to be underwritten for the Company's account and the account of the Holders, Founders and Baby-C Holders, the
Company may include securities for the account of employees, officers, directors and consultants. 

        (c)    Right to Terminate Registration.    The Company shall have the right to terminate or withdraw any registration
initiated by it under this Section 2.5(c) prior to the effectiveness of such registration whether or not any Holder has elected to include Registrable Securities in such registration. 

        2.6    S-3 Registrations.    If the Company is requested (and qualifies under applicable SEC rules) to
undertake a Form S-3 or equivalent short-form registration, regardless of its designation, and any related qualification or compliance, of its securities by the Holders
of Registrable Securities for an offering estimated to result in aggregate offering proceeds of at least $1,000,000, net of underwriting discounts and commissions, the Company shall promptly give
notice of such proposed registration to all Holders of Registrable Securities, Founders and Baby-C Holders and the Company shall, as expeditiously as possible, use all reasonable efforts
to effect the registration on Form S-3 of the Registrable Securities which the Company has been requested to register (i) in such request and (ii) in any response
given within 15 days to a notice from the Company pursuant to this Section 2.6. Notwithstanding the foregoing, however, the Company shall not be required to effect more than two such
registration pursuant to this Section 2.6 in any 12 month period. The substantive provisions of Section 2.4(b) shall be applicable to each registration initiated under this
Section 2.6. 

        Notwithstanding
the foregoing, the Company shall not be obligated to take any action pursuant to this Section 2.6: (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, qualification or compliance unless the Company is already subject to such service in such
jurisdiction and except as may be required by the Securities Act; (ii) if the Company within ten days of the receipt of the request of such Initiating Holders, gives notice of its bona fide
intention to effect the filing of a registration statement with the Commission within 90 days (or 60 days in the case of a registration with respect to a Rule 145
transaction) of receipt of such request (other than with respect to a registration statement relating to an employee benefit plan); (iii) during the period starting with the date 60 days
prior to the Company's estimated date of filing of, and ending on the date three months (or the date a Rule 145 transaction is consummated in the case of a registration relating to such
transaction) immediately following, the effective date of any registration statement pertaining to securities of the Company (other than a registration of securities with respect to an employee
benefit plan), 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 Company shall
furnish to such Holder a certificate signed by the President of the Company stating that in the good faith judgment of the Board of Directors it would be seriously detrimental to the Company or its
shareholders for registration statements to be filed in the near future, then the Company's obligation to use all reasonable efforts to file a registration statement shall be deferred for a
period not to exceed 120 days from the receipt of the request to file such registration by such Holder, provided, however, that the Company may not utilize the right set forth in this
clause (iv) more than once in any 12 month period). 

        The
Company may include in the registration under this Section 2.6 any other shares of Common Stock (including issued and outstanding shares of Common Stock as to which the
holders thereof have contracted with the Company for "piggyback" registration rights pursuant to Section 2.5 hereof or any other similar agreement) so long as the inclusion in such registration
of such shares will not, in the opinion of the managing underwriter (or in the reasonable opinion of the Company in the event that the offering is not underwritten), interfere with the successful
marketing in accordance with the intended method of sale or other disposition of all the shares of Registrable Securities sought to be registered by the Holder or Holders of Registrable Securities
pursuant to this Section 2.6. If it is determined as provided above that there will be such interference, the other shares of Common Stock sought to be included by the Company shall be excluded
to the extent deemed necessary by the managing underwriter (or the Company if the offering is not underwritten), and all other shares of Common Stock held by other parties shall be excluded before the
exclusion of any shares of Registrable Securities held by the Holders who desire to have their shares included in the registration and offering. If, as contemplated above, and after excluding all
other shares of Common Stock held by other parties, shares of the Common Stock of the Holders are to be excluded, the number of shares of Common Stock of each participating Holder which are to be
excluded shall be proportionate to the number of shares which such party is seeking to 

register. Registrations effected pursuant to this Section 2.6 shall not be construed as registrations effected pursuant to Section 2.4 or 2.5. 

        2.7    Expenses of Registration.    All Registration Expenses incurred in connection with any registration,
qualification or compliance pursuant to Section 2.4, 2.5 and 2.6 shall be borne by the Company. If a registration proceeding is begun upon the request of Initiating Holders pursuant to
Section 2.4, but such request is subsequently withdrawn, then the Holders of Registrable Securities to have been registered may either: (i) bear all Registration Expenses of such
proceeding, pro rata on the basis of the number of shares to have been registered, in which case the Company shall be deemed not to have effected a registration pursuant to Section 2.4(a) of
this Agreement; or (ii) require the Company to bear all Registration Expenses of such proceeding, in which case the Company shall be deemed to have effected a registration pursuant to
Section 2.4(a) of this Agreement. Notwithstanding the foregoing, however, if at the time of the withdrawal, 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, then the Holders shall not be required to pay any of said Registration Expenses. In such case, the
Company shall be deemed not to have effected a registration pursuant to Section 2.4(a) of this Agreement. Unless otherwise stated, all other Selling Expenses relating to securities registered
on behalf of the Holders shall be borne by the Holders of the registered securities included in such registration pro rata on the basis of the number of shares so registered. 

        2.8    Registration Procedures.    In the case of each registration, qualification or compliance effected by the
Company pursuant to this Section 2, the Company will keep each Holder advised in writing as to the initiation of each registration, qualification and compliance and as to the completion
thereof. At its expense the Company will: 

        (a)  Prepare
and file with the SEC a registration statement with respect to such securities and use reasonable efforts to cause such registration statement to become and
remain effective for at least 180 days or until the Holder or Holders have completed the distribution described in the registration statement relating thereto, whichever first occurs; and 

        (b)  Furnish
to each Holder participating in the registration such number of prospectuses, preliminary prospectuses, final prospectuses and such other documents as such
Holder may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities being sold by such Holder. 

        2.9    Indemnification.    

        (a)  The
Company will, and does hereby undertake to, indemnify and hold harmless each Holder, Founder and Baby-C Holder, each of its officers, directors and
partners, and each person controlling such Holder or Founder within the meaning of Section 15 of the Securities Act, with respect to which registration, qualification or compliance has been
effected pursuant to this Section 2, and each underwriter, if any, and each person who controls any underwriter within the meaning of Section 15 of the Securities Act, against all
expenses, claims, losses, damages and liabilities (or actions in respect thereof), including settlement of any litigation, commenced or threatened, to which they may become subject under the
Securities Act, the Exchange Act, or other federal or state law, arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration
statement, prospectus (preliminary or final), offering circular or other document or amendments thereto, or arising out of or based on any omission (or alleged omission) to state therein a material
fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or arising out of or any violation by the Company
of any federal, state or common law rule or regulation applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or
compliance, and will reimburse each such Holder, Founder and Baby-C Holder, each of its officers, directors and partners, and each person controlling such Holder, Founder or
Baby-C Holder, each such underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating, preparing
or defending any such claim, loss, damage, 

liability or action, provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue
statement or omission or alleged untrue statement or omission, made in reliance upon and in conformity with written information furnished to the Company by an instrument executed by such Holder,
Founder or Baby-C Holder or underwriter expressly for use in connection with such registration. 

        (b)  Each
Holder, Founder and Baby-C Holder will, if Registrable Securities, Founders' Stock or Baby-C Stock held by such Holder, Founder or
Baby-C Holder, as applicable, are included in the securities as to which such registration, qualification or compliance is being effected, indemnify and hold harmless the Company, each of
its directors and officers, agents and employees, each underwriter, if any, of the Company's securities covered by such a registration statement, each person who controls the Company or such
underwriter within the meaning of Section 15 of the Securities Act, and each other such Holder, Founder or Baby-C Holder, each of its officers, directors and partners and each
person controlling such Holder, Founder or Baby-C Holder within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in
respect thereof to which they may become subject) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement,
prospectus, offering circular or other document, or amendments thereto, or any omission (or alleged omission) to state therein a material fact required to be stated therein in light of the
circumstances in which they were made, or necessary to make the statements therein, not misleading, and will reimburse the Company, such Holders, such Founders, such Baby-C Holders, such
directors, officers, persons, underwriters or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage,
liability or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration
statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Company by an instrument executed by such Holder, Founder or
Baby-C Holder expressly for use in connection with such registration; provided, however, that the obligations of such Holders, Founders or Baby-C Holders hereunder shall be
limited to an amount equal to the net proceeds to each such Holder of Registrable Securities, Founders of Founders' Stock or Baby-C Holders of Baby-C Stock, from the sale of
such Registrable Securities, Founders' Stock or Baby-C Stock as contemplated herein. 

        (c)  Each
party entitled to indemnification under this Section 2.9 (the "Indemnified Party") shall give notice to the party required to provide indemnification (the
"Indemnifying Party") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall deliver written notice to the Indemnifying Party of
commencement thereof. The Indemnifying Party, at its sole option, may participate in or assume the defense of any such claim or any litigation resulting therefrom with counsel reasonably satisfactory
to the Indemnified Party, and the Indemnified Party may participate in such defense at Indemnified Party's expense. The failure of any Indemnified Party to give notice as provided herein shall not
relieve the Indemnifying Party of its obligations under this Section 2 except to the extent that such failure to give notice shall materially adversely affect the Indemnifying Party in the
defense of any such litigation. No Indemnifying Party, in the defense of any such claim or litigation shall, except with the consent of each Indemnified Party, consent to entry of any judgment or
enter into any settlement which does not include as an unconditional term a release from liability in respect to such claim or litigation by the claimant or plaintiff to such Indemnified Party. 

        2.10    Information by Holder.    Each Holder whose Registrable Securities, Founder whose Founders' Stock and
Baby-C Holder whose Baby-C Stock is included in any registration shall furnish to the Company such information regarding such Holder, Founder or Baby-C Holder and
the distribution proposed by such Holder, Founder or Baby-C Holder as the Company may reasonably request in writing and as shall be required in connection with any registration,
qualification or compliance referred to in this Section 2. 

        2.11    Rule 144 Reporting.    With a view to making available the benefits of certain rules and regulations of
the Commission which may at any time permit the sale of the Restricted Securities to the public without registration, after such time as a public market exists for the Common Stock of the Company, the
Company agrees to use all reasonable efforts to: 

        (a)  Make
and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times after the effective date
the Company becomes subject to the reporting requirements of the Securities Act or the Exchange Act; 

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

        (c)  Furnish
to the Holder, so long as Holder owns any Registrable Securities, written notice of the Company's qualification as a registrant, as soon as practicable after the
such qualification; the Company further shall furnish forthwith upon request a written statement as to its compliance with the reporting requirements of said Rule 144 (at any time after
90 days after the effective date of the first registration statement filed by the Company for an offering of its securities to the general public), and of its compliance with the Securities Act
and the Securities Exchange Act (at any time after it has become subject to such reporting requirements); the Company shall provide forthwith upon written request a copy of the most recent annual or
quarterly report of the Company, and such other reports and documents of the Company as Purchaser may reasonably request in availing itself of any rule or regulation of the Commission allowing
Purchaser to sell any such securities without registration. 

        2.12    Assignment of Registration Rights.    The rights to cause the Company to register securities and related
rights granted each Holder under Section 2 may not be assigned except: (i) to a purchaser of more than 33,334 shares of Preferred Stock or Conversion Shares by a Holder, provided such
purchaser is reasonably acceptable to the Company, (ii) to a successor entity to a Holder pursuant to a reorganization or recapitalization of a Holder, or (iii) to the constituent
partners or affiliates of a Holder; provided, that the Company receives notice within a reasonable time after such assignment and the transferee agrees in writing to be bound by the provisions hereof. 

        2.13    Termination of Registration Rights.    The registration rights and related rights granted pursuant to
Section 2 shall terminate as to each Holder (and permitted transferee under Section 2.12 above) upon the occurrence of any of the following: 

        (a)  Following
the Company's first registered offering to the public, of its Common Stock and registration of its Common Stock under the Securities Exchange Act of 1934, as
amended, at such time as all Registrable Securities held by such Holder or permitted transferee constitutes less than one percent (1%) of the then outstanding Common Stock of the Company and can be
sold within a given three (3) month period without compliance with the registration requirements of the Securities Act pursuant to Rule 144 (or its successor provision); or 

        (b)  Five
years from the effective date of the Company's first registered offering to the public. 

        2.14    "Market Stand-Off" Agreement.    Any Holder, Founder or Baby-C Holder, if required by
the Company and an underwriter of Common Stock (or other securities) of the Company, shall agree not to sell or otherwise transfer or dispose of any Registrable Securities, Founders Stock or
Baby-C Stock, as the case may be, held by such Holder, Founder or Baby-C Holder during the period not to exceed 180 days as requested by the managing underwriter
following the effective date of the first registration statement of the Company filed under the Securities Act, provided that all officers, directors of the Company and holders of 1% or more of the
Company's outstanding shares not otherwise a party to this Agreement enter into similar agreements and to the extent the underwriter releases any of such officer, director, 1% holder, the underwriter
shall release the other holders pro rata. Such agreement shall be in writing in the form satisfactory to the Company and such underwriter. The Company may impose a stop-transfer
instruction with respect to the shares (or other securities) subject to the foregoing restriction until the end of such period. 

        2.15    Termination of Prior Registration Rights.    The Company, the Series A Investors, the Series B
Investors and the Prior Series C Investors who hold a majority of the issued and outstanding Registrable Securities agree to terminate in its entirety the Fourth Amended and Restated Investor
Rights Agreement pursuant to Section 5.4 thereof and replace the rights granted thereunder with the rights contained in this Agreement. The provisions of this Section 2.15 shall be
effective as to and as against all Holders as defined in the Fourth Amended and Restated Investor Rights Agreement. 

        2.16    Limitation on Additional Registration Rights.    From and after the date of this Agreement, the Company shall
not enter into any agreement granting a holder or perspective holder of any securities of the Company registration rights with respect to such securities unless (i) such new registration
rights, including standoff obligations are on a pari passu basis with those rights of Holders hereunder or (ii) such new registration rights, including standoff obligations are subordinate to
the registration rights
granted to the Holders hereunder. Any such additional parties may execute a counterpart of this Agreement. 

 
 

SECTION 3
  AFFIRMATIVE COVENANTS OF THE COMPANY    
  

        The Company hereby covenants and agrees as follows: 

        3.1    Right of First Offer.    Subject to the terms and conditions specified in this Section 3.1, the Company
hereby grants to each Investor, who holds at least 100,000 shares of Preferred Stock and/or shares of Common Stock issued upon the conversion thereof (as adjusted for any stock splits, consolidations
and the like) (a "Major Investor"), a right of first offer with respect to future sales by the Company of its Securities (as hereinafter defined). Each time the Company proposes to offer subsequent to
the offering under the Series C Preferred Agreement any shares of, or securities convertible into or exchangeable or exercisable for any shares of, any class of its capital stock
("Securities"), the Company shall first make an offering of such Securities to each Major Investor in accordance with the following provisions: 

        (a)  The
Company shall deliver a notice pursuant to Section 5.5 below ("Notice") to each Major Investor stating (i) its bona fide intention to offer such
Securities, (ii) the number of such Securities to be offered, (iii) the price, if any, for which it proposes to offer such Securities, and (iv) the terms of such offer. 

        (b)  Within
15 calendar days after receipt 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 an
amount of such Securities equal to that portion of such Securities which equals the proportion that the number of shares of Common Stock held by such Major Investor (or issuable to such Major Investor
upon conversion of the shares of Preferred held by such Major Investor) bears to the sum of the number of shares of Common Stock then outstanding plus the number of shares of Common Stock issuable
upon conversion of all Preferred Stock of the Company then outstanding. For purposes of this Section 3.1, the term "Major Investor" includes any general partners or affiliates of a Major
Investor. A Major Investor shall be entitled to apportion the right of first offer hereby granted among itself and its partners and affiliates in such proportions as it deems appropriate. 

        (c)  If
all Securities which the Major Investors are entitled to purchase pursuant to this Section 3.1 are not elected to be obtained as provided in
Section 3.1(b) hereof, the Company may, during the 90 day period following the expiration of the period provided in Section 3.1(b) hereof, offer such unsubscribed Securities 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
Securities within such period, or if such agreement is not consummated within 90 days of the execution thereof, the right provided hereunder shall be deemed to be revived. 

        (d)  The
right of first offer in this Section 3.1 shall not be applicable (i) to the issuance or sale of shares of capital stock (or options therefor) to
employees, officers, directors or consultants 

for the primary purpose of soliciting or retaining their services or such other amount as shall have been approved by the Board of Directors, (ii) to the issuance or sale of the Company's
securities to leasing entities or financial institutions in connection with commercial leasing or borrowing transactions, (iii) to or after consummation of a Qualifying Public Offering,
(iv) to any issuances of shares of Common Stock or Preferred Stock in connection with any stock split, stock dividend or recapitalization by the Company, (v) to securities offered in
connection with the acquisition of another corporation by the Company by merger, consolidation, purchase of all or substantially all of the assets or shares of such corporation as shall have been
approved by the Board of Directors, (vi) to the issuance or sale of the Company's securities to strategic partners in connection with licensing or partnering transactions that have been
approved by the Board of Directors, or (vii) to the issuance of any shares of Series C Preferred authorized as of the date of this Agreement. 

        3.2    Affiliate Transactions.    The Company shall not enter into any material transaction (including, without
limitation, the issuance of capital stock, borrowing money or a sale of the Company) with any stockholder or any affiliate of such stockholder without the approval of a majority of the disinterested
members of the Board of Directors. 

        3.3    Assignment.    The rights under Section 3.1 may be assigned to the constituent partners, members or
affiliates of an Investor; provided, that the Company receives notice within a reasonable time after such assignment and the transferee agrees in writing to be bound by the provisions hereof. 

        3.4    Termination of Covenants.    The covenants set forth in Section 3.1 and 3.2 shall terminate on, and be
of no further force or effect after, the closing of the Qualifying Public Offering. 

 
 

SECTION 4
  RIGHT OF FIRST REFUSAL    
  

        4.1    Restriction on Transfer.    No Investor, Founder or Baby-C Holder shall transfer, assign,
hypothecate, encumber, pledge or otherwise alienate (hereinafter "transfer") any Registrable Securities, Founder's Stock or Baby-C Stock held by such Investor, Founder or
Baby-C Holder, unless such Investor, Founder or Baby-C Holder has previously complied with all provisions of this Section 4. Any transfer not made in accordance with
this Section 4 shall be voidable by the Company, and the Company shall not be obligated to treat the transferee in such transaction as a shareholder for any purpose. 

        4.2    Notice Requirement.    If an Investor, Founder or Baby-C Holder seeks to transfer any Registrable
Securities, Founder's Stock or Baby-C Stock of the Company, whether voluntarily or involuntarily, such Investor, Founder or Baby-C Holder (the "Offering Shareholder") shall
first give written notice of such intention ("Notice of Transfer") to the Secretary of the Company. The Notice of Transfer shall name the proposed transferee, specify the number and class of the
Registrable Securities, Founder's Stock or Baby-C Stock of the Company to be transferred (the "Offered Shares"), and state the price and all other terms of the proposed transaction. The
Notice of Transfer shall constitute an irrevocable offer to sell the Offered Shares during the Company Option Period and the Investor Option Period, each as defined in Section 4.4 hereof. 

        4.3    Special Provisions Regarding Noncash Consideration.    If the Notice of Transfer specifies consideration other
than cash, then the Offered Shares may be purchased in cash for the net fair market value of such property, as determined in good faith by an independent appraiser. 

        4.4    Option of Company and Major Investors.

        (a)    Option of Company.    For 15 days following the deemed receipt of a Notice of Transfer (the "Company
Option Period"), the Company shall have an irrevocable right to purchase the Offered Shares in accordance with the terms stated in the Notice of Transfer. The right may be exercised by a written
notice, signed by the Company, stating that the Company desires to purchase the Offered Shares and tendering the purchase price therefor. Such notice shall be delivered to the Offering Shareholder
before expiration of the Company Option Period. Failure to respond in writing within said fifteen (15) day period to the Notice of Transfer shall be deemed an 

irrevocable waiver by the Company of the Company's right to acquire the shares of the Offered Shares. 

        (b)    Option of Major Investors.    If the Company does not exercise its right to acquire all of the shares of
Offered Shares, then the Company shall send to each Major Investor a Notice of Transfer (the "Investor Notice of Transfer") containing the same information set forth above with respect to the Notice
of Transfer, the number of Offered Shares available for purchase and the pro rata share of such Offered Shares which each Major Investor has a right to purchase. The Investor Notice of Transfer shall
constitute an irrevocable offer to sell the remaining Offered Shares during the Investor Option Period. For fifteen (15) days following the termination of the Company Option Period (the
"Investor Option Period"), the Major Investors shall have an irrevocable right to purchase the remaining Offered Shares in accordance with the terms stated in the Investor Notice of Transfer. Each of
the Major Investors (excluding the Offering Shareholders) shall have the option to purchase that proportion of the shares available for purchase as the number of shares of Common Stock issuable upon
conversion of the Preferred Stock owned by such Major Investor bears to the total number of shares of Common Stock issuable upon conversion of all outstanding Preferred Stock of the Company held by
Major Investors participating in the sale (excluding such shares held by the Offering Shareholders). The right may be exercised by a written notice, signed by each Major Investor who chooses to
exercise such right, stating that the Major Investor desires to purchase the Offered Shares and tendering the purchase price
therefor. Such notice shall be delivered to the Offering Shareholder and the Company before expiration of the Investor Option Period. Failure to respond in writing within said Investor Option Period
to the Investor Notice of Transfer shall be deemed an irrevocable waiver by such Major Investor of such Major Investor's right to acquire a proportionate part of the shares of the Offered Shares. 

        4.5    Transfer of Shares.    If all of the Offered Shares are not purchased and paid for by the Company and the Major
Investors within the applicable Option Periods, said Offered Shares may be transferred, at any time within ninety (90) days after delivery of the Notice of Transfer, to the proposed transferee
in strict accordance with the terms specified in the Notice of Transfer. If such transfer is not made within said ninety (90) day period in strict accordance with the terms specified in the
Notice of Transfer, the Offered Shares shall not be transferred except in accordance with the restrictions of this Section 4. 

        4.6    Effect of Notice.    The purchase price for Offered Shares shall be deemed tendered, and said Offered Shares
shall be deemed purchased, at such time as the Offering Shareholder receives written notice enclosing a cashier's check for the purchase price or stating that the purchase price has been delivered to
a third party (such as counsel to the Company) with instructions to deliver such amount to the Offering Shareholder upon surrender of certificates representing the Offered Shares, duly endorsed with
signatures guaranteed. All rights accorded the Offering Shareholder with respect to the Offered Shares, other than the right to payment therefor, shall cease at that time. If payment is tendered
directly to the Offering Shareholder, the Offering Shareholder shall promptly cause to be delivered certificates representing the Offered Shares, duly endorsed with signatures guaranteed, to the
Company's transfer agent for cancellation or transfer. 

        4.7    Certain Exemptions.    An Investor, Founder or Baby-C Holder may make (i) a gift of shares
of the Company to his or her spouse, issue, other members of his or her immediate family, to a custodian for the benefit of such Investor's issue or to a trust for the benefit of such Investor,
spouse, issue or other members or (ii) a distribution to such Investor's partners, members, equity owners and affiliates, or (iii) a transfer to such Investors' partners, members, equity
owners and affiliates, without complying with the provisions of this Section 4. Such transferees shall hold such shares of the Company subject to the right of first refusal set forth in this
Section 4 and shall be required to confirm same in writing prior to receipt of such shares. 

        4.8    Pledge of Stock.    An Investor or Founder may pledge shares of the Company to the Company or a bank or other
financial institution, provided that the pledge or security agreement under which the shares of the Company are pledged specifies that the pledgee shall not sell or transfer the shares of the 

Company (other than to an Investor or Founder upon termination of the pledge) without first offering the same to the Company and the Major Investors pursuant to the provisions of this
Section 4. 

        4.9    Assignment.    The rights under this Section 4 may be assigned to the constituent partners or
stockholders or affiliates of an Investor; provided, that the Company receives notice within a reasonable time after such assignment and the transferee agrees in writing to be bound by the provisions
hereof. 

        4.01    Termination.    The restrictions imposed by this Section 4 shall terminate on, and be of no further
force or effect after, the closing of the Company's first registered offering to the general public. Securities received pursuant to any stock dividend, stock split, recapitalization, or exercise of a
conversion right shall be subject to this Section 4 to the same extent as the shares of the Company with respect to which they were issued. 

 
 

SECTION 5
  MISCELLANEOUS    
  

        5.1    Governing Law.    This Agreement shall be governed in all respects by the internal laws of the State of
Delaware. 

        5.2    Successors and Assigns.    Except as otherwise provided herein, the provisions hereof shall inure to the
benefit of, and be binding upon, the successors, assigns, heirs, executors and administrators of the parties hereto. 

        5.3    Entire Agreement.    This Agreement constitutes the full and entire understanding and agreement between the
parties with regard to the subject matter hereof. 

        5.4    Amendment.    Any term of this Agreement may be amended, and the observance of any term of this Agreement may
be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and the holders of a majority of the then outstanding
Registrable Securities; provided, that any amendment that disproportionately affects any Holder shall not be effective against such Holder unless such
Holder has consented to such amendment, an provided further, that any amendment to this Agreement which solely adds as new Investors parties who
purchase Series C Preferred Stock of the Company pursuant to the Series C Preferred Agreement shall not require any approval by the holders of Registrable Securities or the Company and
may be effected by adding additional signature pages and additional Exhibit A pages hereto. For purposes of the foregoing clause, the granting of
additional registration rights by the Company to any holder or prospective holder of the Company's shares shall not be deemed to adversely affect the rights granted Founders under this Agreement. Any
amendment or waiver effected in accordance with this Section 5.4 shall be binding upon all Holders of Registrable Securities of the Company. 

        5.5    Notices, etc.    All notices and other communications required or permitted hereunder shall be in writing and
shall be mailed by certified or registered mail or by overnight courier (or if sent to an address outside of the United States, by express air courier or by regular airmail), postage prepaid, or
otherwise delivered by hand or by messenger, addressed (a) if to an Investor, at such Investor's address set forth on Exhibit A or B, or
at such other address as Investor shall have furnished to the Company in writing, or (b) if to any other holder of any Restricted Securities, at such address as such holder shall have furnished
the Company in writing, or, until any such holder so furnishes an address to the Company, then to and at the address of the last holder of such Restricted Securities who has so furnished an address to
the Company, or (c) if to the Company, one copy should be sent to its address set forth on the cover page of this Agreement and addressed to the attention of the Corporate Secretary, or at such
other address as the Company shall have furnished to the Investors. Notice shall be deemed to be given on the earlier of receipt or (if given by certified or registered mail) the third day following
proper deposit in the mail (and if mailed to an address outside of the United States, shall be deemed to be given upon the earlier of receipt or (if given by regular airmail) the fifth day following
proper deposit in the mail if mailed by regular airmail). 

        5.6    Delay or Omissions.    No delay or omission to exercise any right, power or remedy accruing to any holder of
any Restricted Securities upon any breach or default of the Company under this Agreement, shall impair any such right, power or remedy of such holder nor shall it be construed to be a waiver of any
such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other
breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any holder of any breach or default under this Agreement, or any
waiver on the part of any holder of any provisions or conditions of this agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies,
either under this Agreement, or by law or otherwise afforded to any holder, shall be cumulative and not alternative. 

        5.7    Aggregation of Stock.    All shares of Preferred Stock of the Company held by affiliated entities or persons
shall be aggregated together for the purpose of determining the availability or discharge of any rights under this Agreement.

constitute one instrument, and each of which may be executed by less than all of the parties to this Agreement. 

        5.9    Severability.    In the event that any provision of this Agreement becomes or is declared by a court of
competent jurisdiction to be illegal, unenforceable or void, this Agreement shall continue in full force and effect without said provision; provided that no such severability shall be effective if it
materially changes the economic benefit of this Agreement to any party. 

        The
foregoing agreement is effective as of the date first above written.

and the Series B Investors entered into the Rights Agreement as of June 21, 2001. 

        B.    WHEREAS,
the Company, the New Series C Investors, the Prior Series C Investors, the Founders, the Baby-C Holders, the Series A Investors

Section 5.4 of the Rights Agreement provides that any term of the Rights Agreement may be amended with the written consent of the Company and the holders
of a majority of the Registrable Securities. 

        NOW,
THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is acknowledged, and intending to be legally bound, the parties agree as follows: 

        1.    Amendment to Definition of Qualifying Public Offering.    Section 1.12 of the
Rights Agreement is amended and restated in its entirety as follows: 

        "Qualifying Public Offering" shall mean an underwritten public offering pursuant to an effective registration statement under the

commissions and fees) of $20 million and a minimum, per share price of $10 (as appropriately adjusted for all stock splits, stock dividends, combinations, recapitalizations, and the like)." 

        2.    Amendment to Section 4.7.    Section 4.7 of the Rights Agreement is hereby
amended and restated in its entirety with as follows: 

        "4.7  Certain Exemptions.    An Investor, Founder or Baby-C Holder may make (i) a gift of shares of the
Company to his or her spouse, issue, other members of his or her immediate family, to a custodian for the benefit of such Investor's issue or to a trust for the benefit of such Investor, spouse, issue

subject to the right of first refusal set forth in this Section 4 and shall be required to confirm same in writing prior to receipt of such shares." 

        3.    Miscellaneous.    

        (a)    Entire Agreement.    This Amendment and the Rights Agreement constitutes the full and entire agreement between
the parties with regard to the subjects hereof and thereof. 

        (b)    Governing Law.    This Amendment shall be governed in all respects by the internal laws of the State of
Delaware. 

        (c)    Counterparts.    This Amendment may be executed in any number of counterparts, each of which shall be deemed an
original, and all of which together shall constitute one instrument. 

        (d)    Facsimile or Telecopy Signatures.    A facsimile, telecopy or other reproduction of this Amendment may be
executed by one or more parties hereto, and an executed copy of this Amendment may be delivered by one or more parties hereto by facsimile or similar electronic transmission device pursuant to which
