<PAGE>

      2.2 Registration Procedures.

                  (a) If and whenever the Purchaser is required by the
provisions of this Agreement to use its reasonable efforts to effect the
registration of any Registrable Shares under the Securities Act, the Purchaser
shall:

                        (i) file with the Commission a Registration Statement
with respect to such Registrable Shares and use its reasonable efforts to cause
that Registration Statement to become effective as soon as possible;

                        (ii) as expeditiously as possible prepare and file with
the Commission any amendments and supplements to the Registration Statement and
the prospectus included in the Registration Statement as may be necessary to
comply with the provisions of the Securities Act (including the anti-fraud
provisions thereof) and to keep the Registration Statement effective for a
period of time from the effective date and until the date upon which all such
Registrable Shares are no longer deemed to be Registrable Shares;

                        (iii) as expeditiously as possible furnish to each
Selling Stockholder such reasonable numbers of copies of the Prospectus,
including any preliminary Prospectus, in conformity with the requirements of the
Securities Act, and such other documents as such Selling Stockholder may
reasonably request in order to facilitate the public sale or other disposition
of the Registrable Shares owned by such Selling Stockholder;

                        (iv) as expeditiously as possible use its reasonable
efforts to register or qualify the Registrable Shares covered by the
Registration Statement under the securities or Blue Sky laws of such states as
the Selling Stockholders shall reasonably request, and do any and all other acts
and things that may be necessary or desirable to enable the Selling Stockholders
to consummate the public sale or other disposition in such states of the
Registrable Shares owned by the Selling Stockholders; provided, however, that
the Purchaser shall not be required in connection with this paragraph (iv) to
qualify as a foreign corporation or to execute a general consent to service of
process in any jurisdiction or to amend its Certificate of Incorporation or
By-laws in a manner that the Board of Directors of the Purchaser determines is
inadvisable;

                        (v) as expeditiously as possible, cause all such
Registrable Shares to be listed on each securities exchange or automated
quotation system on which similar securities issued by the Purchaser are then
listed;

                        (vi) promptly provide a transfer agent and registrar for
all such Registrable Shares not later than the effective date of such
Registration Statement;

                                      -4-
<PAGE>

                        (vii) promptly make available for inspection by the
Selling Stockholders, any managing underwriter participating in any disposition
pursuant to such Registration Statement, and any attorney or accountant or other
agent retained by any such underwriter or selected by the Selling Stockholders,
all financial and other records, pertinent corporate documents and properties of
the Purchaser and cause the Purchaser's officers, directors, employees and
independent accountants to supply all information reasonably requested by any
such seller, underwriter, attorney, accountant or agent in connection with such
Registration Statement;

                        (viii) notify each Selling Stockholder, promptly after
it shall receive notice thereof, of the time when such Registration Statement
has become effective or a supplement to any Prospectus forming a part of such
Registration Statement has been filed; and

                        (ix) as expeditiously as possible following the
effectiveness of such Registration Statement, notify each seller of such
Registrable Shares of any request by the Commission for the amending or
supplementing of such Registration Statement or Prospectus.

                  (b) If the Purchaser has delivered a Prospectus to the Selling
Stockholders and after having done so the Prospectus is amended to comply with
the requirements of the Securities Act, the Purchaser shall promptly notify the
Selling Stockholders and, if requested, the Selling Stockholders shall
immediately cease making offers of Registrable Shares and return all
Prospectuses to the Purchaser. The Purchaser shall promptly provide the Selling
Stockholders with revised Prospectuses and, following receipt of the revised
Prospectuses, the Selling Stockholders shall be free to resume making offers of
the Registrable Shares.

                  (c) In the event that, in the reasonable judgment of the
Purchaser, it is advisable to suspend use of a Prospectus included in a
Registration Statement due to pending material developments or other events that
have not yet been publicly disclosed and as to which the Purchaser reasonably
believes public disclosure would be detrimental to the Purchaser, the Purchaser
shall notify all Selling Stockholders to such effect, and, upon receipt of such
notice, each such Selling Stockholder shall immediately discontinue any sales of
Registrable Shares pursuant to such Registration Statement until such Selling
Stockholder has received copies of a supplemented or amended Prospectus or until
such Selling Stockholder is advised in writing by the Purchaser that the then
current Prospectus may be used and has received copies of any additional or
supplemental filings that are incorporated or deemed incorporated by reference
in such Prospectus. Notwithstanding anything to the contrary herein, the
Purchaser shall not exercise its rights under this Section 2.2(c) to suspend
sales of Registrable Shares for a period in excess of 30 days consecutively or
60 days in any 365-day period.

            2.3 Allocation of Expenses. The Purchaser will pay all Registration
Expenses for all registrations under this Agreement.

            2.4 Indemnification and Contribution.

                  (a) In the event of any registration of any of the Registrable
Shares under the Securities Act pursuant to this Agreement, the Purchaser will
indemnify and hold harmless each Selling Stockholder, each underwriter of such
Registrable Shares, and each other person, if any, who controls such Selling
Stockholder 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 such Selling Stockholder, underwriter or controlling person
may become subject under the Securities Act, the Exchange Act, state securities
or Blue Sky laws or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon (i)
any untrue statement or alleged untrue statement of any material fact contained
in any Registration Statement under which such Registrable Shares were
registered under the Securities Act, any preliminary prospectus or final
prospectus contained in the Registration Statement, or any amendment or
supplement to such Registration Statement, (ii) the omission or alleged omission
to state 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 Purchaser 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 in connection with the Registration Statement or
the offering contemplated thereby; and the Purchaser will reimburse such Selling
Stockholder, underwriter and each such controlling person for any legal or any
other expenses reasonably incurred by such Selling Stockholder, underwriter or
controlling person in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that the Purchaser will
not be liable in any such case to the extent that any such loss, claim, damage
or liability arises out of or is based upon any untrue statement or omission
made in such Registration Statement, preliminary prospectus or prospectus, or
any such amendment or supplement, in reliance upon and in conformity with
information furnished to the Purchaser, in writing, by or on behalf of such
Selling Stockholder, underwriter or controlling person specifically for use in
the preparation thereof.

                  (b) In the event of any registration of any of the Registrable
Shares under the Securities Act pursuant to this Agreement, each Selling
Stockholder, severally and not jointly, will indemnify and hold harmless the
Purchaser, each of its directors and officers and each underwriter (if any) and
each person, if any, who controls the Purchaser or any such underwriter within
the meaning of the Securities Act or the Exchange Act, against any losses,
claims, damages or liabilities, joint or several, to which the Purchaser, such
directors and officers, underwriter or controlling person may become subject
under the Securities Act, Exchange Act, state securities or Blue Sky laws or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon (i) any untrue statement or
alleged untrue statement of a material fact contained in any Registration
Statement under which such Registrable Shares were registered under the
Securities Act, any preliminary prospectus or final prospectus contained in the
Registration Statement, or any amendment or supplement to the Registration
Statement, or (ii) any omission or alleged omission to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading, if and to the extent (and only to the extent) that the statement or
omission was made in reliance upon and in conformity with information relating
to such Selling Stockholder furnished in writing to the Purchaser by such
Selling Stockholder specifically for use in connection with the preparation of
such Registration Statement, prospectus, amendment or supplement; provided,
however, that the obligations of a Selling Stockholder hereunder shall be
limited to an amount equal to the net proceeds received by such Selling
Stockholder in exchange for the Registrable Shares sold by such Selling
Stockholder in connection with such registration.

                                      -6-
<PAGE>

                  (c) Each Indemnified Party shall give notice to the
Indemnifying Party promptly after such Indemnified Party has actual knowledge of
any claim as to which indemnity may be sought, and shall permit the Indemnifying
Party to assume the defense of any such claim or any litigation resulting
therefrom; provided, that counsel for the Indemnifying Party, who shall conduct
the defense of such claim or litigation, shall be approved by the Indemnified
Party (whose approval shall not be unreasonably withheld, conditioned or
delayed); and, provided, further, that the failure of any Indemnified Party to
give notice as provided herein shall not relieve the Indemnifying Party of its
obligations under this Section 2.4 except to the extent that the Indemnifying
Party is materially adversely affected by such failure. The Indemnified Party
may participate in such defense at such party's expense; provided, however, that
the Indemnifying Party shall pay such expense if the Indemnified Party
reasonably concludes that representation of such Indemnified Party by the
counsel retained by the Indemnifying Party would be inappropriate due to actual
or potential differing interests between the Indemnified Party and any other
party represented by such counsel in such proceeding; provided further that in
no event shall the Indemnifying Party be required to pay the expenses of more
than one law firm per jurisdiction as counsel for the Indemnified Party. The
Indemnifying Party also shall be responsible for the expenses of such defense if
the Indemnifying Party does not elect to assume such defense. No Indemnifying
Party, in the defense of any such claim or litigation shall, except with the
consent of each Indemnified Party, consent to entry of any judgment or enter
into any settlement which does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such Indemnified Party of a release from
all liability in respect of such claim or litigation, and no Indemnified Party
shall consent to entry of any judgment or settle such claim or litigation
without the prior written consent of the Indemnifying Party, which consent shall
not be unreasonably withheld, conditioned or delayed.

                  (d) In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in this Section 2.4 is
due in accordance with its terms but for any reason is held to be unavailable to
an Indemnified Party in respect of any losses, claims, damages and liabilities
referred to herein, then the Indemnifying Party shall, in lieu of indemnifying
such Indemnified Party, contribute to the amount paid or payable by such
Indemnified Party as a result of such losses, claims, damages or liabilities to
which such party may be subject in such proportion as is appropriate to reflect
the relative fault of the Purchaser on the one hand and the Selling Stockholders
on the other in connection with the statements or omissions which resulted in
such losses, claims, damages or liabilities, as well as any other relevant
equitable considerations. The relative fault of the Purchaser and the Selling
Stockholders shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of material fact related to information
supplied by the Purchaser or the Selling Stockholders and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The Purchaser and the Selling Stockholders agree
that it would not be just and equitable if contribution pursuant to this Section
2.4(d) were determined by pro rata allocation or by any other method of
allocation which does not take account of the equitable considerations referred
to above. Notwithstanding the provisions of this Section 2.4(d), (i) in no case
shall any one Selling Stockholder be liable or responsible for any amount in
excess of the net proceeds received by such Selling Stockholder from the
offering of Registrable Shares and (ii) the Purchaser shall be liable and
responsible for any amount in excess of such proceeds; provided, however, that
no person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. Any party entitled to
contribution will, promptly after receipt of notice of commencement of any
action, suit or proceeding against such party in respect of which a claim for
contribution may be made against another party or parties under this Section
2.4(d), notify such party or parties from whom contribution may be sought, but
the omission so to notify such party or parties from whom contribution may be
sought shall not relieve such party from any other obligation it or they may
have thereunder or otherwise under this Section 2.4(d). No party shall be liable
for contribution with respect to any action, suit, proceeding or claim settled
without its prior written consent, which consent shall not be unreasonably
withheld, conditioned or delayed.

                                      -7-
<PAGE>

                  (e) The rights and obligations of the Purchaser and the
Selling Stockholders under this Section 2.4 shall survive the termination of
this Agreement.

            2.5 Information by Holder. Each holder of Registrable Shares
included in any registration shall furnish to the Purchaser such information
regarding such holder and the distribution proposed by such holder as the
Purchaser may reasonably request in writing and as shall be required in
connection with any registration, qualification or compliance referred to in
this Agreement.

            2.6 Confidentiality of Notices. The Company and/or any Member
receiving any written notice from the Purchaser regarding the Purchaser's plans
to file a Registration Statement shall treat such notice confidentially and
shall not disclose such information to any person other than as necessary to
exercise its rights under this Agreement.

            2.7 Termination. Subject to the Company's rights of assignment
pursuant to Section 2.1(d) above, all of the Purchaser's obligations to register
Registrable Shares under Section 2.1 shall terminate upon the date on which the
Company and the Members no longer hold any Registrable Shares.

      3. Covenants.

            3.1 Negative Covenants. So long as the Purchaser remains a holder of
the Company's Class A Units, subject to the termination provisions of Section
3.12 below, the Company shall not, without prior written consent of the
Purchaser:

                  (a) amend or repeal any provision of, or add any provision to,
the Company's Certificate of Formation or Operating Agreement (whether by
merger, consolidation or otherwise) if such action would adversely affect the
rights, preference or privileges of the Class A Units held by the Purchaser,
including, but not limited to, the authorization of additional Class A Units;

                  (b) authorize, designate or issue any class of units in
addition to the units currently outstanding as of the date of this Agreement
(other than pursuant to an option plan or other equity incentive plan approved
by the Board of Directors of the Company, including the approval of one of the
Purchaser's designated Board members);

                  (c) declare or pay any dividend or make any distribution
(other than dividends on Class A Units payable solely in Class A Units) or
permit any Company Subsidiary to declare or pay any dividend or make any
distribution (other than dividends or distributions payable solely to the
Company); provided, however, that the Founding Members may declare or pay
dividends and make distributions (including distributions of Registrable Shares)
once the Company achieves profitability and positive cash flow from operations;

cost upon termination of employment or service, or (ii) pursuant to the right of
first refusal provision contained in Section 3.11 below that is unanimously
approved by the consent or vote of all of the Board members of the Company,
except for the Board members who may be selling such units pursuant to Section
3.11, or in the case of the Purchaser, any of its Board designees), or allocate

members other than in a pro-rata manner based upon the members' pro-rata
ownership interest in the Company;

                  (h) enter into, or permit any Company Subsidiary to enter

confidential information constituting, embodied in or pertaining to such
software, to any person or entity, except that a copy of such source code shall
be provided by the Company to the Purchaser and the Company shall deliver to the
Purchaser an update of such source code, on a quarterly basis, and the Purchaser
will take reasonable measures to prevent disclosure of such source code; or

                  (n) disclose any medical, scientific, clinical or regulatory
matters to any third party, or issue any press release, brochure or any other
public disclosure of such clinical or regulatory matters, without the consent of
the Purchaser, which consent shall not be unreasonably withheld, except as may
be required by law or regulatory process, in which event the Purchaser shall be
given an opportunity to review, in advance, the proposed disclosure; provided,
however, that so long as this Section 3.1(n) shall be applicable, then the
Purchaser shall not disclose any medical, scientific, clinical or regulatory
matters concerning the Company to any third party, or issue any press release,
brochure or any other public disclosure of such clinical or regulatory matters
concerning the Company (except for a non-material reference to the Company),
without the consent of the Company, which consent shall not be unreasonably
withheld, except as may be required by law, in which event the Company shall be
given an opportunity to review, in advance, the proposed disclosure.

            3.2 Affirmative Covenants. So long as the Purchaser remains a holder
of the Company's Class A Units, the Company covenants and agrees that it will

                  (a) Payment of Taxes and Trade Debt. Pay and discharge all
taxes, assessments and governmental charges or levies imposed upon it or upon
its income or profits or business, or upon any properties belonging to it, prior

unpaid, might become a lien or charge upon any properties of the Company or a
Company Subsidiary, other than those which are being contested in good faith if
the Company shall have set aside on its books and shall have provided, in
accordance with generally accepted accounting principles, adequate reserves with
respect thereto; and pay in conformity with customary trade terms, all lease
obligations, all trade debt, and all other indebtedness incident to its
operations, except such as are being contested in good faith if the Company
shall have set aside on its books and shall have provided, in accordance with
generally accepted accounting principles, appropriate reserves with respect
thereto.

                  (b) Maintenance of Insurance. Maintain with responsible and

its corporate existence, rights, franchises and privileges in the jurisdiction
of its organization, and qualify and remain qualified as a foreign limited
liability company in each jurisdiction in which such qualification is required,
unless the failure to so qualify does not and will not have a material and
adverse effect on the business, operations or financial condition of the
Company; and preserve and maintain all material licenses and other rights to use
patents, processes, licenses, trademarks, trade names, inventions, intellectual
property rights or copyrights owned or possessed by it as are reasonably

                  (d) Compliance with Laws. Comply with all applicable laws,
rules, regulations and orders of any governmental authority, noncompliance with
which could materially adversely affect its business or condition, financial or

sufficient reserves, if any, required under generally accepted accounting
principles with respect to such items.

                  (e) Keeping of Records and Books of Account. Keep adequate
records and books of account, in which complete entries will be made in

business shall be made.

                  (f) Maintenance of Properties, etc. Maintain and preserve all
of its properties that the Company reasonably deems material in the proper
conduct of its business in good repair, working order and condition, ordinary

with the provisions of all material leases to which it is a party or under which
it occupies property so as to prevent any material loss or forfeiture thereof or
thereunder.

            3.3 Board Representation and Observation.

                  (a) Upon the execution of this Agreement, the Purchaser shall
have the right to designate three (3) members to the Company's Board of
Directors. Subject to the rights of the Founding Members set forth in Section

outstanding voting equity interests of the Company, the Purchaser shall have the
option to designate four (4) members to the Company's Board of Directors,
constituting a majority of and control the Company's Board of Directors. The
Board of Directors shall at all times consist of not more than 7 members.

                  (b) From the date hereof and until the Purchaser owns at least
a majority of the outstanding voting securities of the Company, a majority of

                  (c) Jeffrey L. Helfer, or such other Company representative

Directors shall have approved, (i) a detailed product development plan, (ii) a
clinical and regulatory plan, (iii) a timetable and (iv) a detailed monthly

                  (a) Provided that a Non-Election or a Funding Default shall

and enter into licensing and/or strategic alliance relationships on behalf of
the Company. The Purchaser shall have prepared a list of acceptable
licensees/partners for which the Purchaser's approval will not be required, as

be required, including the basis for requiring the Company's prior approval, as
set forth on Exhibit C hereto. In the event the Purchaser desires to enter into
a license agreement or a strategic alliance relationship with a licensee/partner
that will require the approval of the Company, the Purchaser shall prepare a
written memorandum identifying, in detail, the basis for a transaction with such
licensee/partner. The Company shall not unreasonably withhold its approval for
such a transaction. Notwithstanding the foregoing, the Purchaser agrees that any
licensing and/or strategic alliance relationship, or Sale Transaction (as
defined in Section 3.13 below) that is consummated in accordance with the
provisions of Section 3.13 below, negotiated and entered into on behalf of the
Company shall contain development and active commercialization milestones (in
appropriate markets) pertaining to the Company's products, technology and
intellectual property, such that if the milestones are not met, the underlying

addition to the foregoing, the Purchaser agrees that it shall not enter into a
licensing and/or strategic alliance relationship on behalf of the Company within
10 months of the date of this Agreement without the consent of the Founding
Members who hold a majority of the outstanding Units then held by all of the
Founding Members.

                  (b) Upon a Non-Election or a Funding Default, the Founding
Members shall have the right to select and enter into licensing and/or strategic
alliance relationships, which relationships shall be brought to the attention of
the Purchaser, and the Purchaser shall be consulted about the relationship prior
to entering into such relationship; provided, however, the approval of the
Purchaser shall not be required. Notwithstanding the foregoing, following a
Control Trigger, the Purchaser's designees that are members of the Company's
Board of Directors shall retain the right to approve such licensing and/or
strategic alliance relationships in their capacity as Board members of the
Company, even upon or after a Non-Election or Funding Default.

                  (a) The Company shall not enter into any agreement with any
member, officer, managing member or member of the Board of Directors of the

rules and regulations promulgated under the Securities Act), including without
limitation any agreement or other arrangement providing for the furnishing of
services by, rental of real or personal property from, or otherwise requiring

            3.10 International Investment and Trade in Services Survey Act. The
Company shall use its best efforts to file on a timely basis all reports
required to be filed by it under 22 U.S.C. Section 3104, or any similar statute,
relating to a foreign person's direct or indirect investment in the Company.

            3.11 Right of First Refusal.

            (a) No Member or the Purchaser (collectively, the "Unitholders" and
individually, a "Unitholder") may transfer any units or any interest in the
Company (collectively referred to herein as "Membership Interests") held by him,
her or it without first complying with this section; provided, however, that
such Unitholder shall be permitted to transfer a Membership Interest to his or
her spouse, children, parents, uncles, aunts, siblings, grandchildren and any
other relatives approved by the Board of Directors (collectively, "Approved
Relatives") or to a trust established solely for the benefit of the Approved
Relatives, or dispose of them under his or her will, or to any other Affiliate
as such term is defined under the Securities Act; provided, that, the transferee
delivers to the Company and the Unitholders a written instrument agreeing to be
bound by the terms of this Agreement as if it were a Unitholder.

                  (b) If any Unitholder desires to transfer any of his, her or
its Membership Interest in any transaction, such Unitholder (the "Selling
Member") shall first deliver written notice of his, her or its desire to do so
(the "Notice") to the Company and each of the other Unitholders, in the manner
prescribed in this Agreement. The Notice must specify: (a) the name and address
of the party to which the Selling Member proposes to sell or otherwise dispose
of the Membership Interest (the "Offeror"), (b) the number of Membership
Interests the Selling Member proposes to sell or otherwise dispose of (the
"Offered Membership Interests"), (c) the consideration per Membership Interest
to be delivered to the Selling Member for the proposed sale, transfer or
disposition, and (d) all other material terms and conditions of the proposed
transaction.

                  (c) The Company shall have the first option to purchase all or
any part of the Membership Interests for the consideration per share and on the
terms and conditions specified in the Notice. Such option shall be exercised by
delivery by the Company of written notice to the Selling Member (the "Company
Notice") within 15 days after receipt of the Notice from the Selling Member. The
Company shall deliver copies of such Company Notice to the Unitholders.

                  (d) The closing of the purchase of the Offered Membership
Interests shall take place at the offices of the Company no later than five days
after the date of the Company Notice. Neither the Company nor any of the
Unitholders shall have any right to purchase any of the Offered Membership
Interests hereunder unless the Company and/or the Unitholders exercise their
option or options to purchase all of the Offered Membership Interests.

<PAGE>

                  (e) To the extent that the consideration proposed to be paid
by the Offeror for the Offered Membership Interests consists of property other
than cash or a promissory note, the consideration required to be paid by the
Company and/or the Unitholders exercising their options under this section may
consist of cash equal to the value of such property, as determined in good faith
by agreement of the Selling Member and the Company and/or the Unitholders
acquiring such Offered Membership Interests.

                  (f) In the event the Company does not exercise its option in
full within such time periods specified in this section with respect to all of
the Offered Membership Interests, the Company shall provide notice of such
decision (the "Non-Exercise Notice") and the Unitholders (other than the Selling
Member) shall have the option to purchase all (but not less than all) of the
number of Offered Membership Interests not purchased by the Company (the
"Remaining Membership Interests"), on a pro rata basis according to the
Membership Interests owned by such Unitholders, for the consideration per share
and on the terms and conditions specified in the Notice. Such option shall be
exercised by delivery by such Unitholder of written notice to the Selling Member
within 15 days after receipt of the Non-Exercise Notice. In the event options to
purchase have been exercised by the Unitholders with respect to some but not all
of the Remaining Membership Interests, those Unitholders who have exercised
their options within such 15-day period shall have an additional option, for a
period of five days next succeeding the expiration of such 15-day period, to
purchase all or any part of the balance of such Remaining Membership Interests
on the terms and conditions set forth in the Notice, which option shall be
exercised by the delivery of written notice to the Selling Member. In the event
there are two or more such Unitholders that choose to exercise the
last-mentioned option for a total number of Remaining Membership Interests in
excess of the number available, the Remaining Membership Interests available for
each such Unitholder's option shall be allocated to such Unitholder pro-rata
based on the Membership Interests owned by the Unitholders so electing.

                  (g) The closing of the purchase of the Remaining Membership
Interests shall take place no later than five days after the expiration of the
latest 15-day period specified in Section 3.11(f).

                  (h) Notwithstanding the foregoing, in the event the Company
and/or the Members do not purchase all of the Offered Membership Interests
within the time periods prescribed by this section, the Selling Member may sell
any or all of the Offered Membership Interests only upon the same terms set
forth in the Notice within 30 days after the expiration of the last 15-day
notice period. If such transaction is not consummated within such 30-day period,
then the Selling Member must again comply with this section.

                  (i) For purposes of this Section 3.11, in the event the
Selling Member is Purchaser, a majority of the Founding Members shall make the
determination for the Company regarding the Company's election to repurchase
pursuant to Section 3.11(c) and, notwithstanding anything to the contrary set
forth in this Section 3.11, the purchase price for such Membership Interests may
be paid by the Company by selling such number of shares of Purchaser Common
Stock equal to the purchase price for such Membership Interests divided by the
closing price per share of the Purchaser Common Stock.

            3.12 Co Sale Rights.

                  (a) If the Company and the Members do not exercise their
options to purchase all of the Offered Membership Interests within the periods
described in this Agreement (the "Option Period"), then all options of the
Company and the Members to purchase the Offered Membership Interests, whether
exercised or not, shall terminate, but each Member which has, pursuant to this
section, expressed a desire to sell Membership Interests in the transaction (a
"Participating Member"), shall be entitled to do so pursuant to this section.
The Company shall promptly, on expiration of the Option Period, notify the
Selling Members of the aggregate number of Membership Interests the
Participating Members wish to sell. The Selling Member shall use his or her best
efforts to interest the Offeror in purchasing, in addition to the Offered
Membership Interests, the Membership Interests the Participating Members wish to
sell. If the Offeror does not wish to purchase all of the Membership Interests
made available by the Selling Member and the Participating Members, then each
Participating Member and the Selling Member shall be entitled to sell, at the
price and on the terms and conditions set forth in the Notice (provided that the
price set forth in the Offer with respect to shares of Common Stock shall be
appropriately adjusted, if necessary, based on the conversion ratio of any
convertible securities to be sold), a portion of the Membership Interests being
sold to the Offeror, in the same proportion as such Selling Member or
Participating Member's ownership of Membership Interests bears to the aggregate
number of Membership Interests owned by the Selling Member and the Participating
members. The transaction contemplated by the Notice shall be consummated not
later than 60 days after the expiration of the Option Period and only for up to
the aggregate number of shares set forth in the Notice.

                  (b) If the Participating Members do not elect to sell the full
number of Membership Interests which they are entitled to sell pursuant to this
section, the Selling Member shall be entitled to sell to the Offeror, according
to the terms set forth in the Notice, that number of his or her own Membership
Interests which equals the difference between the number of Membership Interests
desired to be purchased by the Offeror and the number of Membership Interests
the Participating Members are entitled to sell pursuant to this section. If the
Selling Member wishes to Transfer any such Membership Interests at a price per
Unit which differs from that set forth in the Notice, upon terms different from
those previously offered to the Company and the Members, or more than 60 days
after the expiration of the Option Period, then, as a condition precedent to
such transaction, such Membership Interests must first be offered to the Company
and the Members on the same terms and conditions as given the Offeror, and in
accordance with the procedures and time periods set forth above.

                  (c) The proceeds of any sale made by the Selling Member
without compliance with the provisions of this section shall be deemed to be
held in constructive trust in such amount as would have been due the
Participating Members if the Selling Member had complied with this Agreement.

            3.13 Drag-Along Right. If (i) any person or entity offers to acquire
all or substantially all of the membership interests, stock, assets or business
of the Company, by merger, sale of assets or otherwise, and (ii) such
transaction is approved by the Board of Directors of the Company and (iii) the
Members holding units representing at least 51% of the voting power of the
Membership Interests then held by all Members consent in writing to such
transaction (including by means of a proxy or stockholder consent voting in
favor of such transaction), then each party to this Agreement shall be obligated
to (a) vote all of his, her or its Membership Interests in favor of such
transaction, to the extent any such vote is required for the consummation of
such transaction, (b) if applicable, sell, transfer or exchange all of his, her
or its Membership Interests in connection with such transaction on the same
terms as those consented to by such Members (with appropriate adjustment to
reflect the conversion of convertible securities and the preference and
priorities of any preferred securities), and (c) execute and deliver such
instruments of sale, transfer and exchange and take such other action, including
executing any purchase agreement, merger agreement, indemnity agreement, escrow
agreement or related documents, as may be reasonably required by the Company in
order to carry out the terms and provisions of this section. If a party to this
Agreement fails or refuses to vote or sell his, her or its Membership Interests
as required by, or votes his, her or its Membership Interests in contravention
of this section, then such party hereby grants to the President and Treasurer of
the Company an irrevocable proxy, coupled with an interest, to vote such
Membership Interests in accordance with this section, and hereby appoints the
President and Treasurer of the Company and each of them acting singly, his, her
or its attorney in fact, to sell, transfer or exchange such Membership Interests
in accordance with the terms of this section. At the closing of such
transaction, each of the parties to this Agreement shall deliver, against
receipt of the consideration payable in such transaction, certificates
representing the Membership Interests which such party holds of record or
beneficially, with all endorsements necessary for transfer. In the event that
any party fails or refuses to comply with the provisions of this section, the
Company, the Members and the purchaser in such transaction, at their option, may
elect to proceed with such transaction notwithstanding such failure or refusal
and, in such event and upon tender of the specified consideration to any such
party, the rights of any such party with respect to the Membership Interests of
such party shall cease.

            3.14 Termination of Covenants.

                  (a) Notwithstanding anything in this Agreement to the
contrary, upon a Non-Election event or a Funding Default, the covenants set
forth in Sections 3.1(b), 3.1(d), 3.1(e), 3.1(f), 3.1(g), 3.1(h), 3.1(i),
3.1(j), 3.1(k), 3.1(l), 3.1(m), 3.1(n), 3.3 and 3.4(a) shall terminate and shall
thereafter be null and void. Upon exercise by the Purchaser of the Acceleration
Option (as defined in the Securities Purchase Agreement), the Founding Members
shall have the right to declare and pay dividends and make any distributions,
only up to an amount equal to the Acceleration Option Payment (as defined in the
Securities Purchase Agreement).

                  (b) All covenants contained in this Section 3 shall terminate
after the closing of a Company Sale; provided, however, for the purposes of
clarity, such covenants shall apply to a Company Sale, where applicable.

            4. General.

            4.1 Severability. The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of
any other provision of this Agreement.
