REGISTRATION RIGHTS AGREEMENT

This REGISTRATION
RIGHTS AGREEMENT (this
‘‘Agreement’’) is entered
into as of December  18,  2005, by and between EMCORE
Corporation, a New Jersey corporation (the
‘‘Buyer’’), and Force, Inc.,
a Virginia corporation (the
‘‘Seller’’).

WHEREAS,
pursuant to an Asset Purchase Agreement, dated as of the date hereof
(the ‘‘APA’’; capitalized
terms used and not defined herein shall have the meanings ascribed to
them in the APA) between Buyer and Seller, Buyer will issue
unregistered shares of its common stock, no par value per share (the
‘‘Common Stock’’), as part
of the consideration paid under the APA (such shares, the
‘‘Subject
Stock’’);

WHEREAS, as a condition to
Seller’s obligation to close the transactions contemplated under
the APA, Buyer has agreed to enter into this Agreement with Seller to
provide Seller with ‘‘piggy back’’
registration rights in the Subject Stock; and

WHEREAS,
subject to certain limitations set forth in the APA, and in compliance
with applicable securities laws, Seller may sell the Subject Stock in
one or more transactions exempt from registration under the Securities
Act (defined below) and any applicable state securities laws to one or
more qualified third party investors (each, a
‘‘Transferee’’);

NOW,
THEREFORE, in consideration of the foregoing, the parties to this
Agreement hereby agree as
follows:

1.    ‘‘Piggy-Back’’
Registration Rights.

(a)    Notice of
Registration.    At any time after the issuance of the Subject
Stock and thereafter from time to time, if Buyer shall determine to
register any of its Common Stock for sale in an offering for its own
account on Form S-3 or a successor or similar form (a
‘‘Buyer Registration’’), or
shall register any of its Common Stock on Form S-3 pursuant to a demand
request for registration by any holder of Buyer’s Common Stock
other than Seller (a ‘‘Third Party Demand
Registration’’), Buyer will give to Seller
written notice thereof, if practicable at least thirty (30) days prior
to the effective date of any such registration statement, and otherwise
as promptly as practicable, and include in such registration (subject
to Section 1(b) below) all the Subject Stock specified in a written
request made by Seller within twenty (20) days after Seller’s
receipt of such written notice from Buyer. If such offering is a firm
commitment underwritten offering, the right of Seller to have Subject
Stock included in a registration pursuant to this Section 1(a) shall be
conditioned upon such Seller entering into (together with Buyer and/or
the other holders, if any, distributing their securities through such
underwriting) an underwriting agreement in customary form with the
managing underwriter or underwriters selected for such underwriting by
Buyer or by the stockholders who have demanded such registration (the
‘‘Buyer Underwriter’’). For
clarity, notwithstanding any contrary provision, Seller’s
‘‘piggy back’’ registration rights do not
cover a registration by Buyer relating to (i) a registration of an
employee compensation plan or arrangement adopted in the ordinary
course of business on Form S-8 (or any successor form) or any dividend
reinvestment plan, or (ii) a registration of securities on Form S-4 (or
any successor form) including, without limitation, in connection with a
proposed issuance in exchange for securities or assets of, or in
connection with a merger or consolidation with another
corporation.

(b)    Cutback.    If the lead
managing underwriter of an offering covered by Section 1(a) shall
advise Buyer in writing on or before the date five (5) days prior to
the date then scheduled for such offering that, in its opinion, the
amount of Common Stock (including Subject Stock) requested to be
included in such registration exceeds the amount which can be sold in
such offering without adversely affecting the distribution of the
Common Stock being offered, then Buyer will include in such
registration:

(i)    in the case of a Buyer
Registration, first, any shares proposed to be offered by Buyer;
second, Subject Stock requested to be registered by Seller; and
third, any other shares requested by other stockholders of Buyer
to be included in such registration; and

Table of Contents
(ii)    in the case
of a Third Party Demand Registration, first, any shares proposed
to be offered by the stockholder or stockholders exercising their right
to cause Buyer to proceed with such Third Party Demand Registration
(the ‘‘Initiating Third Party
Holders’’), second, any shares proposed to
be offered by Buyer, and third, Subject Stock requested to be
registered by Seller; and fourth, any other shares requested by
other stockholders of Buyer to be included in such
registration;

provided, however, that in
the event Buyer will not, by virtue of the foregoing cutback mechanism,
include in any such registration all of the Subject Stock requested to
be included in such registration, Seller may, upon written notice to
Buyer given within three (3) days of the time Seller is first notified
of such matter, reduce the amount of Subject Stock Seller desires to
have included in such registration, whereupon only the Subject Stock,
if any, Seller desires to have included will be considered for such
inclusion.

2.    Obligations of
Buyer.

(a)    Whenever Buyer is required by the
provisions of this Agreement to use its reasonable efforts to effect
the registration of any Subject Stock under the Securities Act of 1933,
as amended, (the ‘‘Securities
Act’’), Buyer shall (i) prepare and, as soon as
reasonably possible, file with the Securities and Exchange Commission
(the ‘‘SEC’’) a registration
statement with respect to the shares of Subject Stock, and shall use
its reasonable efforts to cause such registration statement to become
effective and to remain effective until the earlier of the sale of the
shares of Subject Stock so registered or such time as Seller may sell
all of the shares of Subject Stock pursuant to Rule 144 within a three
(3) month period, (ii) prepare and file with the SEC such amendments
and supplements to such registration statement and the prospectus used
in connection therewith as may be reasonably necessary to make and to
keep such registration statement effective and to comply with the
provisions of the Securities Act with respect to the sale or other
disposition of all securities proposed to be registered pursuant to
such registration statement until the earlier of the sale of the shares
of Subject Stock so registered or such time as Seller may sell all of
the shares of Subject Stock pursuant to Rule 144 within a three (3)
month period, and (iii) take all such other action either necessary or
desirable to permit the shares of Subject Stock held by Seller to be
registered and disposed of in accordance with the method of disposition
described herein.

(b)    Notwithstanding the foregoing, if
Buyer shall furnish to Seller a certificate signed by its Chairman,
Chief Executive Officer or Chief Financial Officer stating that (i)
filing a registration statement or maintaining effectiveness of a
current registration statement would have a material adverse effect on
Buyer or its stockholders in relation to any material financing,
acquisition or other corporate transaction, or (ii) Buyer has
determined in good faith that the filing or maintaining effectiveness
of a current registration statement would require disclosure of
material information Buyer has a valid business purpose of retaining as
confidential, Buyer shall be entitled to postpone filing or suspend the
use by Seller of the registration statement for a reasonable period of
time, but not in excess of one hundred twenty (120) consecutive
calendar days; provided that such suspension shall apply to Seller only
if it applies to all parties disposing of shares in the registration.
The Buyer shall be entitled to exercise such suspension rights up to
two (2) times in any calendar year.

(c)    In connection with
any registration statement, the following provisions shall
apply:

(1)    The Buyer shall furnish to
Seller, prior to the filing thereof with the SEC, a copy of any
registration statement, and each amendment thereof and each amendment
or supplement, if any, to the prospectus included therein and shall use
its reasonable efforts to reflect in each such document, when so filed
with the SEC, such comments as Seller and its counsel reasonably may
propose.

(2)    The Buyer shall take such
action as may be necessary so that (i) any registration statement and
any amendment thereto and any prospectus forming part thereof and any
amendment or supplement thereto (and each report or other document
incorporated therein by reference) complies in all material respects
with the Securities Act and the Securities Exchange Act of 1934, as
amended (the ‘‘Exchange
Act’’) and the respective rules and regulations

2

Table of Contents

thereunder, (ii) any registration statement
and any amendment thereto does not, when it becomes effective, contain
an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements
therein not misleading, and (iii) any prospectus forming part of any
registration statement, and any amendment or supplement to such
prospectus, does not include an untrue statement of a material fact or
omit to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made,
not misleading.

(3)    The Buyer shall
advise Seller and, if requested by Seller, confirm such advice in
writing: (i) when a registration statement and any amendment thereto
has been filed with the SEC and when the registration statement or any
post effective amendment thereto has become effective; (ii) of any
request by the SEC for amendments or supplements to the registration
statement or the prospectus included therein or for additional
information; (iii) of the issuance by the SEC of any stop order
suspending effectiveness of the registration statement or the
initiation of any proceedings for that purpose; (iv) of the receipt by
Buyer of any notification with respect to the suspension of the
qualification of the securities included therein for sale in any
jurisdiction or the initiation of any proceeding for such purpose; and
(v) of the happening of any event that requires the making of any
changes in the registration statement or the prospectus so that, as of
such date, the registration statement and the prospectus do not contain
an untrue statement of a material fact and do not omit to state a
material fact required to be stated therein or necessary to make the
statements therein (in the case of the prospectus, in the light of the
circumstances under which they were made) not misleading (which advice
shall be accompanied by an instruction to suspend the use of the
prospectus relating to the Subject Stock until the requisite changes
have been made).

(4)    The Buyer shall use
its reasonable efforts to prevent the issuance, and if issued to obtain
the withdrawal, of any order suspending the effectiveness of the
registration statement relating to the Subject
Stock.

(5)    The Buyer shall furnish to
Seller with respect to the registration statement relating to the
Subject Stock, without charge, such number of copies of such
registration statement and any post-effective amendment thereto,
including financial statements and schedules, and all reports, other
documents and exhibits (including those incorporated by reference) as
Seller shall reasonably request.

(6)    The
Buyer shall furnish to Seller such number of copies of any prospectus
(including any preliminary prospectus and any amended or supplemented
prospectus) relating to the Subject Stock, in conformity with the
requirements of the Securities Act, as Seller may reasonably request in
order to effect the offering and sale of the shares of Subject Stock to
be offered and sold, but only while Buyer shall be required under the
provisions hereof to cause the registration statement to remain
current, and Buyer consents (except during any continuance or
suspension described in this Agreement) to the use of the Prospectus or
any amendment or supplement thereto by Seller in connection with the
offering and sale of the Subject Stock covered by the Prospectus or any
amendment or supplement
thereto.

(7)    Prior to any offering of
Subject Stock pursuant to any registration statement, Buyer shall use
its reasonable efforts to register or qualify the shares of Subject
Stock covered by such registration statement under the securities or
blue sky laws of such states as Seller shall reasonably request,
maintain any such registration or qualification current until the
earlier of (i) the sale of the shares of Subject Stock so
registered, or (ii) ninety (90) days subsequent to the effective date
of the registration statement, and do any and all other acts and things
either reasonably necessary or advisable to enable Seller to consummate
the public sale or other disposition of the shares of Subject Stock in
jurisdictions where Seller desires to effect such sales or other
disposition; provided, however, that Buyer shall not be required
to take any action that would subject it to the general jurisdiction of
the courts of any jurisdiction in which it is not to subject or to
qualify as a foreign corporation in any jurisdiction where Buyer is not
so qualified.

3

Table of Contents
(8)    In connection
with any offering of shares of Subject Stock registered pursuant to
this Agreement, Buyer shall (i) furnish Seller, at Buyer’s
expense, on a timely basis with certificates free of any restrictive
legends representing ownership of the shares of Subject Stock being
sold in such denominations and registered in such names as Seller shall
request, and (ii) instruct the transfer agent and registrar of the
Subject Stock to release any stop transfer orders with respect to the
shares of Subject Stock.

(9)    Upon the
occurrence of any event contemplated by paragraph 2(c)(3)(v) above,
Buyer shall prepare a post effective amendment to any registration
statement or an amendment or supplement to the related prospectus or
file any other required document so that, as thereafter delivered to
purchasers of the Subject Stock included therein, the prospectus will
not include an untrue statement of a material fact or omit to state any
material fact necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading. If Buyer
notifies Seller of the occurrence of any event contemplated by Sections
2(b) or 2(c)(3)(v) above, Seller shall suspend the use of
the prospectus until the requisite changes to the prospectus have been
made.

(10)    The Buyer shall, if
requested, include or incorporate in a prospectus supplement or
post-effective amendment to a registration statement, such information
as the managing underwriters administering an underwritten offering of
the Subject Stock registered thereunder reasonably request to be
included therein and to which Buyer does not reasonably object and
shall make all required filings of such prospectus supplement statement
or post-effective amendment as soon as practicable after they are
notified of the matters to be included or incorporated in such
prospectus supplement or post-effective
amendment.

(11)    The Buyer will use its
reasonable efforts to cause the Subject Stock to be admitted for
quotation on the NASDAQ National Market or other stock exchange or
trading system on which the Common Stock primarily trades on or prior
to the effective date of any registration statement
hereunder.

(12)    The Buyer will provide a
transfer agent and registrar for all Subject Stock registered pursuant
to this Agreement and a CUSIP number for all such Subject Stock, in
each case not later than the effective date of such
registration.

(d)    With a view to making available the
benefits of certain rules and regulations of the SEC which may at any
time permit the sale of the Subject Stock to the public without
registration, Buyer agrees to:

(1)    Make
and keep public information available, as those terms are understood
and defined in and interpreted under Rule 144 (or any successor
provision) of the Securities Act, at all
times;

(2)    During the term of this
Agreement, to furnish to Seller upon request (i) a copy of the most
recent annual or quarterly report of Buyer, and (ii) such other reports
and documents of Buyer as Seller may reasonably request in availing
itself of any rule or regulation of the SEC allowing Seller to sell any
such securities without registration.

(e)    The Buyer shall
have the right to terminate or withdraw any registration initiated by
it under this Section 2 prior to the effectiveness of such
registration, whether or not any stockholder has elected to include
securities in such
registration.

3.    Expenses.    Buyer
shall pay all fees and expenses incurred in connection with the
performance of Buyer’s obligations under Sections 1 and 2
hereof, including without limitation all SEC and blue sky registration
and filing fees, printing expenses, transfer agents’ and
registrars’ fees, and the reasonable fees and disbursements of
Buyer’s outside counsel and independent accountants incurred in
connection with the preparation, filing and amendment of any
registration statement authorized by this Agreement. Seller will pay
all customary underwriting or brokerage commissions and discounts with
respect to the Subject Stock, as well as any fees for counsel to
Seller.

4.    ‘‘Lock-Up’’
Agreement.    Seller agrees (and will require as a condition of
any sale of the Subject Stock in a private placement that the
Transferee also agree), if so requested by the Buyer and an

4

Table of Contents

underwriter of Common Stock or other
securities of the Buyer, not to sell, grant any option or right to buy
or sell, or otherwise transfer or dispose of in any manner, whether in
privately-negotiated or open-market transactions, any Common Stock or
other securities of the Buyer held by it or which it has the right to
acquire up to 180-days following the effective date of a registration
statement filed with the SEC in connection with an offering in
connection with which Seller has been allowed to register all or part
of the Subject Shares as requested by Seller, or such shorter period as
such underwriter shall have advised the Buyer in writing is adequate to
permit the successful and orderly distribution of such Common Stock or
other securities; provided however, that (i) such
‘‘lock-up’’ agreement shall be in writing
and in form and substance reasonably satisfactory to the Buyer and such
underwriter; and (ii) if Seller is notified by the lead managing
underwriter that the amount of Subject Stock to be registered must be
reduced in accordance with the cutback mechanism provided for in
Section 1 above, Seller may elect in writing not to have any of its
Subject Stock included in such registration, in which case Seller shall
not be subject to the lock-up provisions of this Section 4 with respect
to such registration.

5.    Indemnification and
Contribution.

(a)    Indemnification by
Buyer.    In the case of any offering registered pursuant to
this Agreement, Buyer agrees to indemnify and hold Seller and each
underwriter engaged by Seller (if any) of shares of Subject Stock under
such registration statements and each person who controls any of the
foregoing within the meaning of Section 15 of the Securities Act
harmless against any and all losses, claims, damages, liabilities or
amounts paid in settlement as permitted by this Agreement to which they
or any of them may become subject under the Securities Act or any other
statute or common law or otherwise, and to reimburse them, from time to
time upon request, for any legal or other expenses incurred by them in
connection with investigating any claims and defending any actions,
insofar as any such losses, claims, damages, liabilities or actions
shall arise out of or shall be based upon (i) any untrue statement or
alleged untrue statement of a material fact contained in the
registration statement (or any amendment thereto) relating to the sale
of such shares of Subject Stock, including all documents incorporated
therein by reference, or the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, or (ii) any untrue
statement or alleged untrue statement of a material fact contained in
any preliminary prospectus (as amended or supplemented if Buyer shall
have filed with the SEC any amendment thereof or supplement thereto),
if used prior to the effective date of such registration statement or
contained in the prospectus (as amended or supplemented if Buyer shall
have filed with the SEC any amendment thereof or supplement thereto),
if used within the period during which Buyer shall be required to keep
the registration statement to which such prospectus relates current
pursuant to the terms of this Agreement, or the omission or alleged
omission to state therein (if so used) a material fact necessary in
order to make the statements therein, in the light of the circumstances
under which they were made, not misleading; provided, however,
that the indemnification agreement contained in this Section 5(a) shall
not apply to such losses, claims, damages, liabilities or actions which
shall arise from the sale of shares of Subject Stock to any person if
such losses, claims, damages, liabilities or actions shall arise out of
or shall be based upon any such untrue statement or alleged untrue
statement, or any such omission or alleged omission, if such statement
or omission shall have been (x) made in reliance upon and in conformity
with information furnished in writing to Buyer by Seller or any
underwriter engaged by Seller specifically for use in connection with
the preparation of the registration statement or any such amendment
thereof of supplement thereto, or (y) made in any preliminary
prospectus, and the prospectus contained in the registration statement
as declared effective or in the form filed by Buyer with the SEC
pursuant to Rule 424 under the Securities Act shall have corrected such
statement or omission and a copy of such prospectus shall have been
sent or given to such person at or prior to the confirmation to him of
such sale.

(b)    Indemnification by Seller.    In
the case of each offering registered pursuant to this Agreement, Seller
agrees (and will require as a condition of any sale of the Subject
Stock in a private placement that the Transferee also agree) in the
same manner and to the same extent as set forth in Section 5(a) of this
Agreement to indemnify and hold harmless Buyer and each person, if any,
who 

5

Table of Contents

controls Buyer within the meaning of Section
15 of the Securities Act, its directors and those officers of Buyer who
shall have signed any such registration statement with respect to any
statement in or omission from such registration statement or any
preliminary prospectus (as amended or as supplemented, if amended or
supplemented as aforesaid) or prospectus contained in such registration
document (as amended or as supplemented, if amended or supplemented as
aforesaid), if such statement or omission shall have been made in
reliance upon and in conformity with information furnished in writing
to Buyer by Seller specifically for use in connection with the
preparation of such registration statement or any preliminary
prospectus or prospectus contained in such registration statement or
any such amendment thereof of supplement thereto; provided that
Seller’s obligations under this Section 5(b) shall be limited to
the greater of (i) the Cap Amount; and (ii) an amount required by a
Buyer Underwriter as a condition to Seller’s participation in an
underwritten offering.

(c)    Notice of
Claims.    Each party indemnified under Section 5(a) or Section
5(b) of this Agreement shall, promptly after receipt of notice of the
commencement of any action against such indemnified party in respect of
which indemnity may be sought, notify the indemnifying party in writing
of the commencement thereof, enclosing a copy of all papers served on
such indemnified party. The omission of any indemnified party so to
notify an indemnifying party of any such action shall not relieve the
indemnifying party from any liability in respect of such action which
it may have to such indemnified party on account of the indemnity
agreement contained in Section 5(a) or Section 5(b) of this Agreement,
unless the indemnifying party was prejudiced by such omission, and in
no event shall relieve the indemnifying party from any other liability
which it may have to such indemnified party. In case any such action
shall be brought against any indemnified party and it shall notify an
indemnifying party of the commencement thereof, the indemnifying party
shall be entitled to participate therein and, to the extent that it may
wish, jointly with any other indemnifying party similarly notified, to
assume the defense thereof, with counsel satisfactory to such
indemnified party; provided that if any indemnified party or
parties reasonably determine that there may be legal defenses available
to such indemnified party that are different from or in addition to
those available to such indemnifying party or that representation of
such indemnifying party and any indemnified party by the same counsel
would present a conflict of interest, then such indemnifying party
shall not be entitled to assume such defense. If an indemnifying party
assumes the defense of an action in accordance with and as permitted by
the provisions of this paragraph, such indemnifying party shall not be
liable to such indemnified party under Section 5(a) or Section 5(b) of
this Agreement for any legal or other expenses subsequently incurred by
such indemnified party in connection with the defense thereof other
than reasonable costs of investigation. In no event shall the
indemnifying party be liable for the fees and expenses of more than one
counsel (in addition to local counsel) separate from its own counsel
for all indemnified parties in connection with any one action of
separate but similar or related actions in the same jurisdiction
arising out of the same general allegations or
circumstances.

(d)    In order to provide for just and
equitable contribution in circumstances in which the indemnity provided
for in this Section 5 is for any reason held to be unavailable to the
indemnified parties although applicable in accordance with its terms,
Buyer, Seller shall contribute to the aggregate losses, liabilities,
claims, damages and expenses of the nature contemplated by said
indemnity incurred by Buyer and Seller as incurred; provided
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 that was not guilty of such fraudulent
misrepresentation. As between Buyer, on the one hand, and Seller, on
the other hand, such parties shall contribute to such aggregate losses,
liabilities, claims, damages and expenses of the nature contemplated by
such indemnity agreement in such proportion as shall be appropriate to
reflect the relative fault of Buyer, on the one hand, and Seller, on
the other hand, with respect to the statements or omissions which
resulted in such loss, liability, claim, damage or expense, or action
in respect thereof, as well as any other relevant equitable
considerations. The relative fault of Buyer, on the one hand, and of
Seller, on the other hand, 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 Buyer, on the one hand, or by
on behalf of Seller, on the other hand, and the parties’
relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The Buyer 

6

Table of Contents

and Seller agree that it would not be just and
equitable if contribution pursuant to this Section 5 were to be
determined by pro rata allocation or by any other method of allocation
that does not take into account the relevant equitable considerations.
For purposes of this Section 5(d), each person who controls Buyer or
Seller within the meaning of Section 15 of the Securities Act shall
have the same rights to contribution as Seller or Buyer, as the case
may be. No party shall be liable for contribution with respect to any
action, suit, proceeding or claim settled without its written
consent.

(e)    The Buyer may require, as a condition to
entering into any underwriting agreement with respect to the
registration of Subject Stock, that Buyer shall have received an
undertaking reasonably satisfactory to it from each underwriter named
in any such underwriting agreement, severally and not jointly, to
comply with the provisions of paragraphs (a) through (d) of this
Section 5.

(f)    The obligations of Buyer and Seller under
this Section 5 shall survive the completion of any offering of Subject
Stock in a registration
statement.

6.    Notices.    Any notice or
other communication given under this Agreement shall be sufficient if

Obligation.    All registration rights provided hereunder shall

provision thereto during any single three (3) month
period.

12.    No Transfer or Assignment or
Registration Rights.    The registration rights set forth in
this Agreement shall not be transferable or assignable by Seller,
except to the extent permitted under the APA, and in a transaction that

state securities laws; provided that the Transferee shall agree in
writing to be subject to all terms and conditions of this Agreement,
including without limitation the lock-up provisions of Section 4 and
the indemnification and contribution provisions of Section 5. Following
any transfer of such rights permitted by this Section 12, the term
‘‘Seller’’ as used in this Agreement will
be deemed to include such Transferee.

into as of November  8,  2005, by and between EMCORE
Corporation, a New Jersey corporation (the
‘‘Buyer’’), and Phasebridge,
Inc., a Delaware corporation (the
‘‘Seller’’).

WHEREAS,
pursuant to an Asset Purchase Agreement, dated as of the date hereof
(the ‘‘Asset Purchase
Agreement’’; capitalized terms used and not
defined herein shall have the meanings ascribed to them in the Asset
Purchase Agreement) between Buyer and Seller, Buyer will issue
unregistered shares of its common stock, no par value per share (the
‘‘Common Stock’’), as part
of the consideration paid under the Asset Purchase Agreement (such
shares, the ‘‘Subject
Stock’’);

WHEREAS, as a condition to
Seller’s obligation to close the transactions contemplated under
the Asset Purchase Agreement, Buyer has agreed to enter into this
Agreement with Seller to provide Seller with ‘‘piggy
back’’ registration rights in the Subject Stock;
and

WHEREAS, subject to certain limitations set forth in
the Asset Purchase Agreement, and in compliance with applicable
securities laws, Seller may sell the Subject Stock in a transaction
exempt from registration under the Securities Act (defined below) and
any applicable state securities laws to a qualified third party
investor
(‘‘Transferee’’);

NOW,
THEREFORE, in consideration of the foregoing, the parties to this
Agreement hereby agree as
follows:

1.    ‘‘Piggy_Back’’
Registration Rights.

(a)    Notice of
Registration.    At any time after the issuance of the Subject
Stock and thereafter from time to time, if Buyer shall determine to
register any of its Common Stock for sale in an offering for its own
account on Form S-3 or a successor or similar form (a
‘‘Buyer Registration’’), or
shall register any of its Common Stock on Form S-3 pursuant to a demand
request for registration by any holder of Buyer’s Common Stock
other than Seller (a ‘‘Third Party Demand
Registration’’), Buyer will give to Seller
written notice thereof, if practicable at least thirty (30) days prior
to the effective date of any such registration statement, and otherwise
as promptly as practicable, and include in such registration (subject
to Section 1(b) below) all the Subject Stock specified in a written
request made by Seller within twenty (20) days after Seller’s
receipt of such written notice from Buyer. If such offering is a firm
commitment underwritten offering, the right of Seller to have Subject
Stock included in a registration pursuant to this Section 1(a) shall be
conditioned upon such Seller entering into (together with Buyer and/or
the other holders, if any, distributing their securities through such
underwriting) an underwriting agreement in customary form with the
managing underwriter or underwriters selected for such underwriting by
Buyer or by the stockholders who have demanded such registration (the
‘‘Buyer Underwriter’’). For
clarity, notwithstanding any contrary provision, Seller’s
‘‘piggy back’’ registration rights do not
cover a registration by Buyer relating to (i) a registration of an
employee compensation plan or arrangement adopted in the ordinary
course of business on Form S-8 (or any successor form) or any dividend
reinvestment plan, or (ii) a registration of securities on Form S-4 (or
any successor form) including, without limitation, in connection with a
proposed issuance in exchange for securities or assets of, or in
connection with a merger or consolidation with another
corporation.

(b)    Cutback.    If the lead
managing underwriter of an offering covered by Section 1(a) shall
advise Buyer in writing on or before the date five (5) days prior to
the date then scheduled for such offering that, in its opinion, the
amount of Common Stock (including Subject Stock) requested to be
included in such registration exceeds the amount which can be sold in
such offering without adversely affecting the distribution of the
Common Stock being offered, then Buyer will include in such
registration:

(i)    in the case of a Buyer
Registration, first, any shares proposed to be offered by Buyer;
second, Subject Stock requested to be registered by Seller; and
third, any other shares requested by other stockholders of Buyer
to be included in such registration; and

Table of Contents
(ii)    in the case of
a Third Party Demand Registration, first, any shares proposed to
be offered by the stockholder or stockholders exercising their right to
cause Buyer to proceed with such Third Party Demand Registration (the
‘‘Initiating Third Party
Holders’’), second, any shares proposed to
be offered by Buyer, and third, Subject Stock requested to be
registered by Seller; and fourth, any other shares requested by
other stockholders of Buyer to be included in such
registration;

provided, however, that in the event Buyer
will not, by virtue of the foregoing cutback mechanism, include in any
such registration all of the Subject Stock requested to be included in
such registration, Seller may, upon written notice to Buyer given
within three (3) days of the time Seller is first notified of such
matter, reduce the amount of Subject Stock Seller desires to have
included in such registration, whereupon only the Subject Stock, if
any, Seller desires to have included will be considered for such
inclusion.

2.    Obligations of
Buyer.

(a)    Whenever Buyer is required by the
provisions of this Agreement to use its reasonable efforts to effect
the registration of any Subject Stock under the Securities Act of 1933,
as amended, (the ‘‘Securities
Act’’), Buyer shall (i) prepare and, as soon as
reasonably possible, file with the Securities and Exchange Commission
(the ‘‘SEC’’) a registration
statement with respect to the shares of Subject Stock, and shall use
its reasonable efforts to cause such registration statement to become
effective and to remain effective until the earlier of the sale of the
shares of Subject Stock so registered or such time as Seller may sell
all of the shares of Subject Stock pursuant to Rule 144 within a three
(3) month period, (ii) prepare and file with the SEC such amendments
and supplements to such registration statement and the prospectus used
in connection therewith as may be reasonably necessary to make and to
keep such registration statement effective and to comply with the
provisions of the Securities Act with respect to the sale or other
disposition of all securities proposed to be registered pursuant to
such registration statement until the earlier of the sale of the shares
of Subject Stock so registered or such time as Seller may sell all of
the shares of Subject Stock pursuant to Rule 144 within a three (3)
month period, and (iii) take all such other action either necessary or
desirable to permit the shares of Subject Stock held by Seller to be
registered and disposed of in accordance with the method of disposition
described herein.

(b)    Notwithstanding the foregoing, if
Buyer shall furnish to the purchaser a certificate signed by its
Chairman, Chief Executive Officer or Chief Financial Officer stating
that (i) filing a registration statement or maintaining effectiveness
of a current registration statement would have a material adverse
effect on Buyer or its stockholders in relation to any material
financing, acquisition or other corporate transaction, or (ii) Buyer
has determined in good faith that the filing or maintaining
effectiveness of a current registration statement would require
disclosure of material information Buyer has a valid business purpose
of retaining as confidential, Buyer shall be entitled to postpone
filing or suspend the use by Seller of the registration statement for a
reasonable period of time, but not in excess of one hundred twenty
(120) consecutive calendar days; provided that such suspension shall
apply to Seller only if it applies to all parties disposing of shares
in the registration. The Buyer shall be entitled to exercise such
suspension rights up to two (2) times in any calendar
year.

(c)    In connection with any registration statement,
the following provisions shall
apply:

(1)    The Buyer shall furnish to
Seller, prior to the filing thereof with the SEC, a copy of any
registration statement, and each amendment thereof and each amendment
or supplement, if any, to the prospectus included therein and shall use
its reasonable efforts to reflect in each such document, when so filed
with the SEC, such comments as Seller and its counsel reasonably may
propose.

(2)    The Buyer shall take such
action as may be necessary so that (i) any registration statement and
any amendment thereto and any prospectus forming part thereof and any
amendment or supplement thereto (and each report or other document
incorporated therein by reference) complies in all material respects
with the Securities Act and the Securities Exchange Act of 1934, as
amended (the ‘‘Exchange
Act’’) and the respective rules and regulations

2

Table of Contents

thereunder, (ii) any registration statement
and any amendment thereto does not, when it becomes effective, contain
an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements
therein not misleading, and (iii) any prospectus forming part of any
registration statement, and any amendment or supplement to such
prospectus, does not include an untrue statement of a material fact or
omit to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made,
not misleading.

(3)    The Buyer shall advise
Seller and, if requested by Seller, confirm such advice in writing: (i)
when a registration statement and any amendment thereto has been filed
with the SEC and when the registration statement or any post effective
amendment thereto has become effective; (ii) of any request by the SEC
for amendments or supplements to the registration statement or the
prospectus included therein or for additional information; (iii) of the
issuance by the SEC of any stop order suspending effectiveness of the
registration statement or the initiation of any proceedings for that
purpose; (iv) of the receipt by Buyer of any notification with respect
to the suspension of the qualification of the securities included
therein for sale in any jurisdiction or the initiation of any
proceeding for such purpose; and (v) of the happening of any event that
requires the making of any changes in the registration statement or the
prospectus so that, as of such date, the registration statement and the
prospectus do not contain an untrue statement of a material fact and do
not omit to state a material fact required to be stated therein or
necessary to make the statements therein (in the case of the
prospectus, in the light of the circumstances under which they were
made) not misleading (which advice shall be accompanied by an
instruction to suspend the use of the prospectus relating to the
Subject Stock until the requisite changes have been
made).

(4)    The Buyer shall use its
reasonable efforts to prevent the issuance, and if issued to obtain the
withdrawal, of any order suspending the effectiveness of the
registration statement relating to the Subject
Stock.

(5)    The Buyer shall furnish to
Seller with respect to the registration statement relating to the
Subject Stock, without charge, such number of copies of such
registration statement and any post-effective amendment thereto,
including financial statements and schedules, and all reports, other
documents and exhibits (including those incorporated by reference) as
Seller shall reasonably request.

(6)    The
Buyer shall furnish to Seller such number of copies of any prospectus
(including any preliminary prospectus and any amended or supplemented
prospectus) relating to the Subject Stock, in conformity with the
requirements of the Securities Act, as Seller may reasonably request in
order to effect the offering and sale of the shares of Subject Stock to
be offered and sold, but only while Buyer shall be required under the
provisions hereof to cause the registration statement to remain
current, and Buyer consents (except during any continuance or
suspension described in this Agreement) to the use of the Prospectus or
any amendment or supplement thereto by Seller in connection with the
offering and sale of the Subject Stock covered by the Prospectus or any
amendment or supplement thereto.

(7)    Prior
to any offering of Subject Stock pursuant to any registration
statement, Buyer shall use its reasonable efforts to register or
qualify the shares of Subject Stock covered by such registration
statement under the securities or blue sky laws of such states as
Seller shall reasonably request, maintain any such registration or
qualification current until the earlier of (i) the sale of
the shares of Subject Stock so registered, or (ii) ninety (90) days
subsequent to the effective date of the registration statement, and do
any and all other acts and things either reasonably necessary or
advisable to enable Seller to consummate the public sale or other
disposition of the shares of Subject Stock in jurisdictions where
Seller desires to effect such sales or other disposition; provided,
however, that Buyer shall not be required to take any action that
would subject it to the general jurisdiction of the courts of any
jurisdiction in which it is not to subject or to qualify as a foreign
corporation in any jurisdiction where Buyer is not so
qualified.

3

Table of Contents
(8)    In connection
with any offering of shares of Subject Stock registered pursuant to
this Agreement, Buyer shall (i) furnish Seller, at Buyer’s
expense, on a timely basis with certificates free of any restrictive
legends representing ownership of the shares of Subject Stock being
sold in such denominations and registered in such names as Seller shall
request, and (ii) instruct the transfer agent and registrar of the
Subject Stock to release any stop transfer orders with respect to the
shares of Subject Stock.

(9)    Upon the
occurrence of any event contemplated by paragraph 2(c)(3)(v) above,
Buyer shall prepare a post effective amendment to any registration
statement or an amendment or supplement to the related prospectus or
file any other required document so that, as thereafter delivered to
purchasers of the Subject Stock included therein, the prospectus will
not include an untrue statement of a material fact or omit to state any
material fact necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading. If Buyer
notifies Seller of the occurrence of any event contemplated by Sections
2(b) or 2(c)(3)(v) above, Seller shall suspend the use of the
prospectus until the requisite changes to the prospectus have been
made.

(10)    The Buyer shall, if requested,
include or incorporate in a prospectus supplement or post-effective
amendment to a registration statement, such information as the managing
underwriters administering an underwritten offering of the Subject
Stock registered thereunder reasonably request to be included therein
and to which Buyer does not reasonably object and shall make all
required filings of such prospectus supplement statement or
post-effective amendment as soon as practicable after they are notified
of the matters to be included or incorporated in such prospectus
supplement or post-effective
amendment.

(11)    The Buyer will use its
reasonable efforts to cause the Subject Stock to be admitted for
quotation on the Nasdaq National Market or other stock exchange or
trading system on which the Common Stock primarily trades on or prior
to the effective date of any registration statement
hereunder.

(12)    The Buyer will provide a
transfer agent and registrar for all Subject Stock registered pursuant
to this Agreement and a CUSIP number for all such Subject Stock, in
each case not later than the effective date of such
registration.

(d)    With a view to making available the
benefits of certain rules and regulations of the SEC which may at any
time permit the sale of the Subject Stock to the public without
registration, Buyer agrees to:

(1)    Make
and keep public information available, as those terms are understood
and defined in and interpreted under Rule 144 (or any successor
provision) of the Securities Act, at all
times;

(2)    During the term of this
Agreement, to furnish to Seller upon request (i) a copy of the most
recent annual or quarterly report of Buyer, and (ii) such other reports
and documents of Buyer as Seller may reasonably request in availing
itself of any rule or regulation of the SEC allowing Seller to sell any
such securities without registration.

(e)    The Buyer shall
have the right to terminate or withdraw any registration initiated by
it under this Section 2 prior to the effectiveness of such
registration, whether or not any stockholder has elected to include
securities in such
registration.

3.    Expenses.    Buyer
shall pay all fees and expenses incurred in connection with the
performance of Buyer’s obligations under Sections 1 and 2
hereof, including without limitation all SEC and blue sky registration
and filing fees, printing expenses, transfer agents’ and
registrars’ fees, and the reasonable fees and disbursements of
Buyer’s outside counsel and independent accountants incurred in
connection with the preparation, filing and amendment of any
registration statement authorized by this Agreement. Seller will pay
all customary underwriting or brokerage commissions and discounts with
respect to the Subject Stock, as well as any fees for counsel to
Seller.

4.    ‘‘Lock-Up’’
Agreement.    Seller agrees (and will require as a condition of
any sale of the Subject Stock in a private placement that the
Transferee also agree), if so requested by the Buyer and an

4

Table of Contents

underwriter of Common Stock or other
securities of the Buyer, not to sell, grant any option or right to buy
or sell, or otherwise transfer or dispose of in any manner, whether in
privately-negotiated or open-market transactions, any Common Stock or
other securities of the Buyer held by it or which it has the right to
acquire up to 180-days following the effective date of a registration
statement filed with the SEC in connection with an offering in
connection with which Seller has been allowed to register all or part
of the Subject Shares as requested by Seller, or such shorter period as
such underwriter shall have advised the Buyer in writing is adequate to
permit the successful and orderly distribution of such Common Stock or
other securities; provided however, that (i) such
‘‘lock-up’’ agreement shall be in writing
and in form and substance reasonably satisfactory to the Buyer and such
underwriter; and (ii) if Seller is notified by the lead managing
underwriter that the amount of Subject Stock to be registered must be
reduced in accordance with the cutback mechanism provided for in
Section 1 above, Seller may elect in writing not to have any of its
Subject Stock included in such registration, in which case Seller shall
not be subject to the lock-up provisions of this Section 4 with respect
to such registration.

5.    Indemnification and
Contribution.

(a)    Indemnification by
Buyer.    In the case of any offering registered pursuant to
this Agreement, Buyer agrees to indemnify and hold Seller and each
underwriter engaged by Seller (if any) of shares of Subject Stock under
such registration statements and each person who controls any of the
foregoing within the meaning of Section 15 of the Securities Act
harmless against any and all losses, claims, damages, liabilities or
amounts paid in settlement as permitted by this Agreement to which they
or any of them may become subject under the Securities Act or any other
statute or common law or otherwise, and to reimburse them, from time to
time upon request, for any legal or other expenses incurred by them in
connection with investigating any claims and defending any actions,
insofar as any such losses, claims, damages, liabilities or actions
shall arise out of or shall be based upon (i) any untrue statement or
alleged untrue statement of a material fact contained in the
registration statement (or any amendment thereto) relating to the sale
of such shares of Subject Stock, including all documents incorporated
therein by reference, or the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, or (ii) any untrue
statement or alleged untrue statement of a material fact contained in
any preliminary prospectus (as amended or supplemented if Buyer shall
have filed with the SEC any amendment thereof or supplement thereto),
if used prior to the effective date of such registration statement or
contained in the prospectus (as amended or supplemented if Buyer shall
have filed with the SEC any amendment thereof or supplement thereto),
if used within the period during which Buyer shall be required to keep
the registration statement to which such prospectus relates current
pursuant to the terms of this Agreement, or the omission or alleged
omission to state therein (if so used) a material fact necessary in
order to make the statements therein, in the light of the circumstances
under which they were made, not misleading; provided, however,
that the indemnification agreement contained in this Section 5(a) shall
not apply to such losses, claims, damages, liabilities or actions which
shall arise from the sale of shares of Subject Stock to any person if
such losses, claims, damages, liabilities or actions shall arise out of
or shall be based upon any such untrue statement or alleged untrue
statement, or any such omission or alleged omission, if such statement
or omission shall have been (x) made in reliance upon and in conformity
with information furnished in writing to Buyer by Seller or any
underwriter engaged by Seller specifically for use in connection with
the preparation of the registration statement or any such amendment
thereof of supplement thereto, or (y) made in any preliminary
prospectus, and the prospectus contained in the registration statement
as declared effective or in the form filed by Buyer with the SEC
pursuant to Rule 424 under the Securities Act shall have corrected such
statement or omission and a copy of such prospectus shall have been
sent or given to such person at or prior to the confirmation to him of
such sale.

(b)    Indemnification by Seller.    In
the case of each offering registered pursuant to this Agreement, Seller
agrees (and will require as a condition of any sale of the Subject
Stock in a private placement that the Transferee also agree) in the
same manner and to the same extent as set forth in Section 5(a) of this
Agreement to indemnify and hold harmless Buyer and each person, if any,
who 

5

Table of Contents

controls Buyer within the meaning of Section
15 of the Securities Act, its directors and those officers of Buyer who
shall have signed any such registration statement with respect to any
statement in or omission from such registration statement or any
preliminary prospectus (as amended or as supplemented, if amended or
supplemented as aforesaid) or prospectus contained in such registration
document (as amended or as supplemented, if amended or supplemented as
aforesaid), if such statement or omission shall have been made in
reliance upon and in conformity with information furnished in writing
to Buyer by Seller specifically for use in connection with the
preparation of such registration statement or any preliminary
prospectus or prospectus contained in such registration statement or
any such amendment thereof of supplement
thereto.

(c)    Notice of Claims.    Each party
indemnified under Section 5(a) or Section 5(b) of this Agreement shall,
promptly after receipt of notice of the commencement of any action
against such indemnified party in respect of which indemnity may be
sought, notify the indemnifying party in writing of the commencement
thereof, enclosing a copy of all papers served on such indemnified
party. The omission of any indemnified party so to notify an
indemnifying party of any such action shall not relieve the
indemnifying party from any liability in respect of such action which
it may have to such indemnified party on account of the indemnity
agreement contained in Section 5(a) or Section 5(b) of this Agreement,
unless the indemnifying party was prejudiced by such omission, and in
no event shall relieve the indemnifying party from any other liability
which it may have to such indemnified party. In case any such action
shall be brought against any indemnified party and it shall notify an
indemnifying party of the commencement thereof, the indemnifying party
shall be entitled to participate therein and, to the extent that it may
wish, jointly with any other indemnifying party similarly notified, to
assume the defense thereof, with counsel satisfactory to such
indemnified party; provided that if any indemnified party or
parties reasonably determine that there may be legal defenses available
to such indemnified party that are different from or in addition to
those available to such indemnifying party or that representation of
such indemnifying party and any indemnified party by the same counsel
would present a conflict of interest, then such indemnifying party
shall not be entitled to assume such defense. If an indemnifying party
assumes the defense of an action in accordance with and as permitted by
the provisions of this paragraph, such indemnifying party shall not be
liable to such indemnified party under Section 5(a) or Section 5(b) of
this Agreement for any legal or other expenses subsequently incurred by
such indemnified party in connection with the defense thereof other
than reasonable costs of investigation. In no event shall the
indemnifying party be liable for the fees and expenses of more than one
counsel (in addition to local counsel) separate from its own counsel
for all indemnified parties in connection with any one action of
separate but similar or related actions in the same jurisdiction
arising out of the same general allegations or
circumstances.

(d)    In order to provide for just and
equitable contribution in circumstances in which the indemnity provided
for in this Section 5 is for any reason held to be unavailable to the
indemnified parties although applicable in accordance with its terms,
Buyer, Seller shall contribute to the aggregate losses, liabilities,
claims, damages and expenses of the nature contemplated by said
indemnity incurred by Buyer and Seller as incurred; provided
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 that was not guilty of such fraudulent
misrepresentation. As between Buyer, on the one hand, and Seller, on
the other hand, such parties shall contribute to such aggregate losses,
liabilities, claims, damages and expenses of the nature contemplated by
such indemnity agreement in such proportion as shall be appropriate to
reflect the relative fault of Buyer, on the one hand, and Seller, on
the other hand, with respect to the statements or omissions which
resulted in such loss, liability, claim, damage or expense, or action
in respect thereof, as well as any other relevant equitable
considerations. The relative fault of Buyer, on the one hand, and of
Seller, on the other hand, 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 Buyer, on the one hand, or by
on behalf of Seller, on the other hand, and the parties’
relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The Buyer and Seller
agree that it would not be just and equitable if contribution pursuant
to this Section 5 were to be determined by pro rata allocation or by
any other method of allocation that does not take into 

6

Table of Contents

account the relevant equitable considerations.
For purposes of this Section 5(d), each person who controls Buyer or
Seller within the meaning of Section 15 of the Securities Act shall
have the same rights to contribution as Seller or Buyer, as the case
may be. No party shall be liable for contribution with respect to any
action, suit, proceeding or claim settled without its written
consent.

(e)    The Buyer may require, as a condition to
entering into any underwriting agreement with respect to the
registration of Subject Stock, that Buyer shall have received an
undertaking reasonably satisfactory to it from each underwriter named
in any such underwriting agreement, severally and not jointly, to
comply with the provisions of paragraphs (a) through (d) of this
Section 5.

(f)    The obligations of Buyer and Seller under
this Section 5 shall survive the completion of any offering of Subject
Stock in a registration
statement.

6.    Notices.    Any notice or
other communication given under this Agreement shall be sufficient if
in writing and sent by nationally-recognized overnight courier via
next-business-day service to a party at its address set forth below (or

to the benefit of the parties hereto and their respective successors
and assigns.

10.    Severability.    If

and shall in no way be affected, impaired or

11.    Termination of Buyer
Obligation.    All registration rights provided hereunder shall
terminate upon such time as Seller is able to sell all of the Subject
Stock without registration under the Securities Act or any successor
provision thereto during any single three (3) month
period.

12.    No Transfer or Assignment or
Registration Rights.    The registration rights set forth in
this Agreement shall not be transferable or assignable by Seller,
except to the extent permitted under the Asset Purchase Agreement, and
in a transaction that is exempt from registration under the Securities
Act and any applicable state securities laws; provided that the
Transferee shall agree in writing to be subject to all terms and
conditions of this Agreement, including without limitation the lock-up
provisions of Section 4 and the indemnification and contribution
provisions of Section 5. Following any transfer of such rights
permitted by this Section 12, the term
‘‘Seller’’ as used in this Agreement will
be deemed to include such Transferee.
