hereof shall have been received by the Company after the Company shall have

of Registrable Securities requested to be included therein by each such Investor
Stockholder; (ii) if the Underwriters’ Maximum Number exceeds the number of

Securities on the basis of the number of Other Registrable Securities requested
to be included therein by each such Holder; (iii) if the Underwriters’ Maximum

the account of the Company and which shall not be greater than such excess, and
(iv) if the Underwriters’ Maximum Number exceeds the sum of the number of
Registrable Securities which the Company shall be required to include in such

registration not withdrawn or abandoned prior to the effective date thereof
being herein called a “Piggyback Registration”), the Company will give written

Registrable Securities shall have entered into a written agreement with the
Company’s underwriters establishing the terms and conditions under which such
Holders would be obligated to sell such securities in such Piggyback
Registration. The Company will not be obligated or required to include any
Registrable Securities in any registration effected solely to implement an

account in such registration and which does not exceed the Underwriters’ Maximum

registration rights proposes to offer and sell in such registration, then the
Company will be obligated and required to include in such registration that
number of Investor Registrable Securities requested by the Holders thereof to be
included in such registration and which does not exceed such excess and such
Investor Registrable Securities shall be allocated pro rata among the Holders
thereof on the basis of the number of Investor Registrable Securities requested

account in such registration, then the Company will be obligated and required to
include in such registration that number of Other Registrable Securities
requested by the Holders thereof to be included in such registration and which
does not exceed such excess and such Other Registrable Securities shall be
allocated pro rata among the Holders thereof on the basis of the number of Other
Registrable Securities requested to be included therein by each such Holder, and
(iv) if the Underwriters’ Maximum Number exceeds the sum of the number of the
Investor Registrable Securities which the Company shall be required to include
in such registration pursuant to clauses (ii) and (iii) and the number of
securities which the Company and stockholders exercising demand registration
rights proposes to offer and sell for its own account in such registration, then

seven (7) days prior to, and during the one hundred eighty (180) day period
commencing on, the effective date of such underwritten registration, except in
connection with such underwritten registration. As long as such restrictions

Securities that are permitted to be sold without such restrictions.
 
(b) Restrictions on Public Sale by the Company. The Company agrees not to effect
any public sale or other distribution of its equity securities, or any

or omits any fact necessary to make the statements therein not misleading, and,
at the request of any such seller, the Company will promptly prepare (and, when
completed, give notice to each seller of Registrable Securities) a supplement or
amendment to such Prospectus so that, as thereafter delivered to the purchasers
of such Registrable Securities, such Prospectus will not contain an untrue
statement of a material fact or omit to state any fact necessary to make the
statements therein not misleading; provided that upon such notification by the
Company, each seller of such Registrable Securities will not offer or sell such
Registrable Securities until the Company has notified such seller that it has
prepared a supplement or amendment to such Prospectus and delivered copies of
such supplement or amendment to such seller;

the first sale of such Registrable Securities pursuant to such registration, on

or a combination of shares);
 
(ix) make available for inspection on a confidential basis by any seller, any
underwriter participating in any disposition pursuant to such Registration
Statement, and any attorney, accountant or other agent retained by any such

person of the Company within the meaning of Section 15 of the Securities Act, to
participate in the preparation of such registration or comparable statement and
to permit the insertion therein of material, furnished to the Company in

be included, provided that such material shall be furnished under such
circumstances as shall cause it to be subject to the indemnification provisions
provided pursuant to Section 8(b) hereof;

the type customarily covered by “cold comfort letters” as the Holders of a
majority of the Registrable Securities covered by such registration and the
underwriters reasonably request; and
 
(B) at the time of any underwritten sale pursuant to a Registration Statement, a
“bring-down comfort letter”, dated as of the date of such sale, from the

type customarily covered by comfort letters as the Holders of a majority of the
Registrable Securities covered by such Registration Statement and the
underwriters reasonably request;
 
(xvi) use its best efforts to obtain, at the time of effectiveness of each
Piggyback Registration and at the time of any sale pursuant to each
registration, an opinion or opinions, favorable in form and scope to the Holders
of a majority of the Registrable Securities covered by such registration, from
counsel to the Company in customary form; and

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

 
6. Cooperation by Prospective Sellers, Etc.
 
(a) Each prospective seller of Registrable Securities will furnish to the
Company in writing such information as the Company may reasonably require from
such seller, and otherwise reasonably cooperate with the Company in connection
with any Registration Statement with respect to such Registrable Securities.
 
(b) The failure of any prospective seller of Registrable Securities to furnish
any information or documents in accordance with any provision contained in this
Agreement shall not affect the obligations of the Company under this Agreement
to any remaining sellers who furnish such information and documents unless in
the reasonable opinion of counsel to the Company or the underwriters, such
failure impairs or may impair the viability of the offering or the legality of
the Registration Statement or the underlying offering.
 
(c) The Holders of Registrable Securities included in any Registration Statement
will not (until further notice) effect sales thereof after receipt of
telegraphic or written notice from the Company to suspend sales to permit the
Company to correct or update such Registration Statement or Prospectus; but the
obligations of the Company with respect to maintaining any Registration
Statement current and effective shall be extended by a period of days equal to
the period such suspension is in effect.
 
(d) At the end of any period during which the Company is obligated to keep any
Registration Statement current and effective as provided by Section 5 hereof
(and any extensions thereof required by the preceding paragraph (c) of this
Section 6), the Holders of Registrable Securities included in such Registration
Statement shall discontinue sales of shares pursuant to such Registration
Statement upon receipt of notice from the Company of its intention to remove
from registration the shares covered by such Registration Statement which remain
unsold, and such Holders shall notify the Company of the number of shares
registered which remain unsold promptly after receipt of such notice from the
Company.
 
(e) Notwithstanding any other provision herein to the contrary, no Holder of
Registrable Securities which constitute warrants or options shall be required to
exercise such warrants or options in connection with any registration until the
actual sale of the shares of Common Stock issuable upon exercise of such
warrants or options. The Company shall enter into such agreements and shall
otherwise cooperate with the Holders of Registrable Securities in order to
ensure that such Holders are not required to exercise any warrants or options
prior to the date of the actual sale of the shares of Common Stock issuable upon
exercise of such warrants or options.
 
-14-

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

 
7. Registration Expenses.
 
(a) All costs and expenses incurred or sustained in connection with or arising
out of each registration pursuant to Sections 2 and 3 hereof, including, without
limitation, all registration and filing fees, fees and expenses of compliance
with securities or blue sky laws (including reasonable fees and disbursements of
counsel for the underwriters in connection with the blue sky qualification of
Registrable Securities), printing expenses, messenger, telephone and delivery
expenses, fees and disbursements of counsel for the Company, reasonable fees and
disbursements of one counsel representing the Holders of Registrable Securities,
such counsel to be selected by the Holders of a majority of the Registrable
Securities to be included in such registration, fees and disbursements of all
independent certified public accountants (including the expenses relating to the
preparation and delivery of any special audit or “cold comfort” letters required
by or incident to such registration), and fees and disbursements of underwriters
(excluding discounts and commissions), the reasonable fees and expenses of any
special experts retained by the Company of its own initiative or at the request
of the managing underwriters in connection with such registration, and fees and
expenses of all (if any) other Persons retained by the Company (all such costs
and expenses being herein called, collectively, the “Registration Expenses”),
will be borne and paid by the Company. The Company will, in any case, pay its
internal expenses (including, without limitation, all salaries and expenses of
its officers and employees performing legal or accounting duties), the expense
of any annual audit, and the fees and expenses incurred in connection with the
listing of the securities to be registered on each securities exchange on which
similar securities of the Company are then listed.
 
(b) The Company will not bear the cost of nor pay for any stock transfer taxes
imposed in respect of the transfer of any Registrable Securities to any
purchaser thereof by any Holder of Registrable Securities in connection with any
registration of Registrable Securities pursuant to this Agreement.
 
(c) To the extent that Registration Expenses incident to any registration are,
under the terms of this Agreement, not required to be paid by the Company, each
Holder of Registrable Securities included in such registration will pay all
Registration Expenses which are clearly solely attributable to the registration
of such Holder’s Registrable Securities so included in such registration, and
all other Registration Expenses not so attributable to one Holder will be borne
and paid by all sellers of securities included in such registration in
proportion to the number of securities so included by each such seller.
 
8. Indemnification.
 
(a) Indemnification by the Company. The Company will indemnify each Holder
requesting or joining in a registration and each underwriter of the securities
so registered, the officers, directors and partners of each such Person and each
Person who controls any thereof (within the meaning of the Securities Act)
against any and all claims, losses, damages and liabilities (or actions in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of any material fact contained in any Prospectus, offering
circular or other document incident to any registration, qualification or
compliance (or in any related Registration Statement, notification or the like)
or any omission (or alleged omission) to state therein any material fact
required to be stated therein or necessary to make the statements therein not
misleading, or any violation by the Company of any rule or regulation
promulgated under the Securities Act applicable to the Company and relating to
any action or inaction required of the Company in connection with any such
registration, qualification or compliance, and the Company will reimburse each
such Holder, underwriter, officer, director, partner and controlling person for
any legal and any other expenses reasonably incurred in connection with
investigating or defending any such claim, loss, damage, liability or action;
provided, however, that the Company will not be liable in any such case to the
extent that any such claim, loss, damage or liability arises out of or is based
on any untrue statement or omission based upon written information furnished to
the Company by such Holder, underwriter, officer, director, partner or
controlling person and stated to be specifically for use in such Prospectus,
offering circular or other document (or related Registration Statement,
notification or the like).
 
-15-

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

 
(b) Indemnification by Each Holder. Each Holder requesting or joining in a
registration will indemnify each underwriter of the securities so registered,
the Company and its officers and directors and each Person, if any, who controls
any thereof (within the meaning of the Securities Act) and their respective
successors in title and assigns against any and all claims, losses, damages and
liabilities (or actions in respect thereof) arising out of or based on any
untrue statement (or alleged untrue statement) of any material fact contained in
any Prospectus, offering circular or other document incident to any
registration, qualification or compliance (or in any related Registration
Statement, notification or the like) or any omission (or alleged omission) to
state therein any material fact required to be stated therein or necessary to
make the statement therein not misleading, and such Holder will reimburse each
underwriter, the Company and each other Person indemnified pursuant to this
paragraph (b) for any legal and any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage,
liability or action; provided, however, that this paragraph (b) shall apply only
if (and only to the extent that) such statement or omission was made in reliance
upon written information furnished to such underwriter or the Company by such
Holder in writing and stated to be specifically for use in such Prospectus,
offering circular or other document (or related Registration Statement,
notification or the like) or any amendment or supplement thereto; and,
provided further, that each Holder’s liability hereunder with respect to any
particular registration shall be limited to an amount equal to the net proceeds
received by such Holder from the Registrable Securities sold by such Holder in
such registration.
 
(c) Indemnification Proceedings. Each party entitled to indemnification pursuant
to this Section 8 (the “Indemnified Party”) shall give notice to the party
required to provide indemnification pursuant to this Section 8 (the
“Indemnifying Party”) promptly after such Indemnified Party acquires actual
knowledge of any claim as to which indemnity may be sought, and shall permit the
Indemnifying Party (at its expense) to assume the defense and settlement of any
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 acceptable to the Indemnified Party, and the Indemnified Party may
participate in such defense at such party’s expense; and provided, further, that
the failure by any Indemnified Party to give notice as provided in this
paragraph (c) shall not relieve the Indemnifying Party of its obligations under
this Section 8 except to the extent that the failure results in a failure of
actual notice to the Indemnifying Party and such Indemnifying Party is damaged
solely as a result of the failure to give notice. 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 to such claim or litigation. The reimbursement required by this
Section 8 shall be made by periodic payments during the course of the
investigation or defense, as and when bills are received or expenses incurred.
 
-16-

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

 
9. Contribution in Lieu of Indemnification. If the indemnification provided for
in Section 8 hereof is unavailable to a party that would have been an
Indemnified Party under such Section in respect of any losses, claims, damages
or liabilities (or actions in respect thereof) referred to therein, then each
party that would have been an Indemnifying Party thereunder 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 (or actions in respect thereof) in such proportion as is appropriate
to reflect the relative fault of the Indemnifying Party on the one hand and such
Indemnified Party on the other in connection with the statements or omissions
which resulted in such losses, claims, damages or liabilities (or actions in
respect thereof). The relative fault shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Indemnifying Party or such Indemnified Party and the
parties’ relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The Company and each Holder of
Registrable Securities agree that it would not be just and equitable if
contribution pursuant to this Section 9 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 in this Section 9. The amount paid or
payable by an Indemnified Party as a result of the losses, claims, damages or
liabilities (or actions in respect thereof) referred to above in this Section 9
shall include any legal or other expenses reasonably incurred by such
Indemnified Party in connection with investigating or defending any such action
or claim. Notwithstanding any provision of this Section 9 to the contrary, (a)
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 and (b) each Holder’s
liability hereunder with respect to any particular registration shall be limited
to an amount equal to the net proceeds received by such Holder from the
Registrable Securities sold by such Holder in such registration.
 
10. Eligibility Requirements. After the date hereof, the Company will make
reasonable efforts in good faith to take all steps necessary to ensure that the
Company will be eligible to register securities on Form SB-2, as long as the
Company is a “small business issuer”, or Form S-3 (or any comparable forms
adopted by the Commission) as soon thereafter as possible, and to make publicly
available and available to the Holders of Registrable Securities, pursuant to
Rule 144 or Rule 144A of the Commission under the Securities Act, such
information as shall be necessary to enable the Holders of Registrable
Securities to make sales of Registrable Securities pursuant to such Rules. The
Company will furnish to any Holder of Registrable Securities, upon request made
by such Holder, a written statement signed by the Company, addressed to such
Holder, describing briefly the action the Company has taken or proposes to take
to comply with the current public information requirements of Rule 144 and Rule
144A.
 
-17-

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

 
11. Participation in Underwritten Registrations. (a) No Person may participate
in any underwritten registration pursuant to this Agreement unless such Person
(i) agrees to sell such Person’s securities on the basis provided in any
underwriting arrangements approved by the Persons entitled, under the provisions
hereof, to approve such arrangements, and (ii) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents reasonably required by the terms of such underwriting
arrangements. Any Holder of Registrable Securities to be included in any
underwritten registration shall be entitled at any time to withdraw such
Registrable Securities from such registration prior to its effective date in the
event that such Holder shall disapprove of any of the terms of the related
underwriting agreement.
 
(b) Notwithstanding the priorities set forth in Sections 2(c) and 3(b) above, in
the event that the managing underwriters in any underwritten Demand Registration
or Piggyback Registration inform the Company in writing that the inclusion
therein of any Other Registrable Securities held by management employees of the
Company or any of its subsidiaries would impair the marketability of the
Registrable Securities to be included in such registration, the Company shall be
required to include in such registration only such number of Other Registrable
Securities held by such management employees as the managing underwriters
determine would not negatively impair the Registrable Securities to be sold in
connection therewith. If any such event shall occur, the other Holders of
Registrable Securities (other than any Holder affected by the restriction
described above) shall be entitled to include in such registration, the number
of Registrable Securities that Holders of Other Registrable Securities would
have been entitled to include in such registration but for such restriction
described above (such Registrable Securities to be allocated pro rata among such
other Holders on the basis of the number of Registrable Securities requested to
be included therein by each such Holder).
 
-18-

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

 
12. Miscellaneous.
 
(a) No Inconsistent Agreements. The Company has not previously entered into any
agreement with respect to its Common Stock granting any registration rights to
any Person, and will not on or after the date of this Agreement enter into any
agreement with respect to its securities which grants demand registration rights
to anyone or which is inconsistent with the rights granted to the Holders of
Registrable Securities in this Agreement or otherwise conflicts with the
provisions hereof.
 
(b) Amendments and Waivers. The provisions of this Agreement, including the
provisions of this sentence, may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof may not be given,
unless such amendment, modification, supplement, waiver or consent is approved
in writing by the Holders of at least fifty-one percent (51%) of the Investor
Registrable Securities, the Holders of at least fifty-one percent (51%) of the
Registrable Securities and the Company; provided, however, that no amendment,
modification or waiver of any provision of this Agreement that adversely affects
the rights of any Party (as hereinafter defined) to this Agreement in a manner
different from the rights of the other Parties shall be effective against such
adversely affected Party unless approved in writing by the holders of at least a
majority of the Registrable Securities then held by all members of such Party.
As used in this Section 12(b), “Party” means any one of the following entities
or groups: (i) the Company, (ii) the Holders of Investor Registrable Securities,
and (iii) the Holders of Other Registrable Securities. Section 2(a)(i)(B) and
the second and third sentences of Section 2(b)(i) may not be amended, modified
or supplemented, and waivers or consents to departures from such provisions may
not be given, unless such amendment, modification, supplement, waiver or consent
is approved in writing by Baldwin.
 
(c) Registrable Securities Held by the Company. Whenever the consent or approval
of Holders of Registrable Securities is required pursuant to this Agreement,
Registrable Securities held by the Company shall not be counted in determining
whether such consent or approval was duly and properly given by such Holders.
 
(d) Term. The agreements of the Company contained in this Agreement shall
continue in full force and effect so long as any Holder holds any Registrable
Securities.
 
(e) Remedies. In the event of a breach by the Company of its obligations under
this Agreement, each Holder, in addition to being entitled to exercise all
rights granted by law, including recovery of damages, will be entitled to
specific performance of its rights under this Agreement. The Company agrees that
monetary damages would not be adequate compensation for any loss incurred by
reason of a breach by it of any of the provisions of this Agreement and hereby
agrees to waive the defense in any action for specific performance that a remedy
at law would be adequate.
