made, not misleading, and, as promptly as practicable make available to the
Holder any such supplement or amendment.

to Section 2.2(c), the Holder’s intended plan of distribution of the Units,
necessary to comply with legal requirements in connection with the preparation

requirements of the Securities Act and will not 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.  The Holder also agrees to notify the
Partnership if any event relating to the Holder occurs that would require the
preparation of a supplement or amendment to the prospectus so that such
prospectus will not 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, in the light of the circumstances under which they were
made, not misleading.

2.3           Documents to be Furnished to the
Holder.  The Partnership shall
furnish to the Holder at least two business days prior to filing with the
Commission the Resale Registration Statement, any amendment or supplement to
the Resale Registration Statement, any prospectus to be used in connection
therewith and any amendment or supplement to any such prospectus, which
documents will be subject to the reasonable review of the Holder, and the
Partnership shall not file any such documents with the Commission to which the
Holder shall reasonably object until the Holder and the Partnership have in
good faith resolved any of the Holder’s objections, unless the Partnership in
good faith believes that the filing of such documents is required by law.

 4
 

2.4                                 Certain
Notices.

(a)           Upon
notice to the Holder, the Partnership may delay the filing of the Resale
Registration Statement otherwise required pursuant to Section 2.2 or require
the Holder to suspend the use of the prospectus or any prospectus supplement
related to the Resale Registration Statement, for a reasonable period time, if
the Partnership would be required to disclose material information it was not
otherwise then required by law to disclose publicly where the Partnership
reasonably deems it advisable not to disclose or incorporate by reference such
information in a registration statement, prospectus or supplement.  The Partnership shall use commercially
reasonable efforts to limit such suspension periods to no more than 60
consecutive days or 90 days in the aggregate, but in no event shall such
periods exceed 90 consecutive days or 120 days in the aggregate.  Any periods under this Section 2.4(a)
shall be aggregated with periods under Section 2.4(b) in determining
whether the periods of 90 consecutive days or 120 days have been
exceeded.  During any such period, the
Partnership’s obligations under Section 2.2(a)(viii) are suspended.

(b)           The Holder agrees that, upon receipt
of any notice from the Partnership of the happening of any event of the kind
described in Section 2.2(a)(viii) hereof, the Holder will forthwith
discontinue disposition of Units pursuant to the Resale Registration Statement
until the Holder’s receipt of the copies of the supplemented or amended
prospectus contemplated by Section 2.2(a)(viii), and, if so directed by
the Partnership, the Holder will deliver to the Partnership (at the
Partnership’s expense) all copies, other than permanent file copies, then in
the Holder’s possession, of the prospectus and any prospectus supplement
covering such Units current at the time of receipt of such notice.

Section 3

Expenses

3.1           Registration Expenses.  The Partnership agrees to bear and to pay or
cause to be paid promptly upon request being made therefor all third party
expenses incident to the Partnership’s performance of or compliance with this
Agreement, including (a) all Commission filing fees; (b) all fees and
expenses in connection with the qualification of the securities being
registered for offering and sale under the state securities and blue sky laws
referred to in Section 2.2(a)(vi), including reasonable fees and
disbursements of its counsel, in connection with such qualifications;

hereunder, each prospectus included therein or prepared for distribution
pursuant hereto, each amendment or supplement to the foregoing, and all other
documents relating hereto; (d) fees, disbursements and expenses of counsel
and independent certified public accountants of the Partnership in connection
with the Resale Registration Statement; (e) fees, expenses and disbursements of

Holder, and any selling fees, discounts or commissions.

Section 4

Representations and Warranties

4.1           Representations and Warranties of
the Partnership.  The Partnership
represents and warrants to, and agrees with, the Holder that:

(a)           The Partnership has reasonable
grounds to believe that it meets all the requirements for the filing of a
registration statement on Form S-3 with the Commission.  The Resale Registration Statement, at the
time it becomes effective, and the final prospectus contained therein, will
comply, and when any post-effective amendment to the Resale Registration
Statement becomes effective or any supplement to such prospectus is filed with
the Commission, the Registration Statement, the final prospectus and any such
amendment or supplement, respectively, will comply, in all material respects
with the applicable requirements of the Securities Act and the applicable rules
adopted by the Commission thereunder; the documents incorporated, or deemed to
be incorporated, into the Resale Registration Statement or the related
prospectus by reference pursuant to the requirements of Item 12 of Form S-3
under the Securities Act, when they were or are filed with the Commission,
conformed or will conform as of their respective dates in all material respects
with the applicable requirements of the Securities Exchange Act of 1934, as
amended, and the applicable rules and regulations adopted by the Commission
thereunder; and each part of the Resale Registration Statement and any
amendment thereto, at the time it became effective, and the final prospectus
and any amendment or supplement thereto, at the time it was filed with the
Commission pursuant to Rule 424 under the Securities Act, will not contain an
untrue statement of a material fact or omit to a state a material fact required
to be stated therein or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading; and at all
times at and subsequent to the time when the Resale Registration Statement has
been declared effective under the Securities Act, other than (i) from such time
as a notice has been given to the Holder pursuant to Section 2.2(a)(viii)
until such time as the Partnership furnishes an amended or supplemented
prospectus pursuant to Section 2.2(a)(viii) or such earlier time as the
Partnership provides notice that offers and sales pursuant to the Resale
Registration Statement may continue, or (ii) during any period when the Holder
is to suspend use of the prospectus or prospectus supplement related to the
Resale Registration Statement as provided in Section 2.4(a), each prospectus
contained in or prepared in connection with any Resale Registration Statement,
and each prospectus furnished pursuant to Section 2.2(a)(iv), as then
amended or supplemented, will conform in all material respects to the applicable
requirements of the Securities Act and will not contain an untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading; provided, however, that this
representation and warranty in this Section 4.1(a) shall not apply to any
statements or omissions made in reliance upon and in conformity with
information furnished in writing to the Partnership by or on behalf of the
Holder expressly for use therein in any such Resale Registration Statement,
prospectus or supplement.

(b)           The execution, delivery and
performance of this Agreement by the Partnership will not (i) result in a
breach or violation of any of the terms and provisions of the limited
partnership agreement of the Partnership, (ii) constitute a breach or
default under any

 6
 

material agreement or
contract to which the Partnership is a party, except where any such foregoing
occurrence will not prevent the consummation of the transactions contemplated
herein or would not have a material adverse effect on the Partnership and its
subsidiaries taken as a whole, or (iii) result in a violation of any
provision of law, statute, rule, regulation, or any existing applicable decree,
judgment or order of any court or governmental agency or body having
jurisdiction over the Partnership.

(c)           This Agreement has been duly
authorized, executed and delivered by the Partnership.

4.2           Representations and Warranties of
the Holder.  The Holder represents
and warrants to, and agrees with, the Partnership that:

(a)           The execution, delivery and
performance of this Agreement by the Holder will not (i) result in a
breach or violation of any of the terms and provisions of the certificate of
incorporation or bylaws of the Holder, (ii) constitute a breach or default
under any material agreement or contract to which the Holder is a party, except
where any such foregoing occurrence will not prevent the consummation of the
transactions contemplated herein or would not have a material adverse effect on
the Holder and its subsidiaries taken as a whole, or (iii) result in a
violation of any provision of law, statute, rule, regulation, or any existing
applicable decree, judgment or order of any court or governmental agency or
body having jurisdiction over the Holder.

(b)           This Agreement has been duly
authorized, executed and delivered by the Holder.

Section 5

Indemnification and Contributions

5.1           (a)           The
Partnership will indemnify and hold harmless the Holder against any losses,
claims, damages or liabilities, joint or several, to which the Holder may
become subject, under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon an untrue statement or alleged untrue statement of a material
fact contained in any preliminary prospectus, any Resale Registration Statement
or any prospectus, or any amendment or supplement thereto, or arise out of or
are based upon 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, and will reimburse the Holder for any legal or other expenses
reasonably incurred by the Holder in connection with investigating or defending
any such action or claim as such expenses are incurred; provided, however, that the Partnership shall 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 an untrue statement or alleged untrue statement or
omission or alleged omission made in any preliminary prospectus, any Resale
Registration Statement or any prospectus or any such amendment or supplement in
reliance upon and in conformity with written information furnished to the
Partnership by the Holder expressly for use therein.

 7
 

(b)           The Holder will indemnify and hold
harmless the Partnership against any losses, claims, damages or liabilities,
joint or several, to which the Partnership may become subject, under the
Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in
any preliminary prospectus, any Resale Registration Statement or any
prospectus, or any amendment or supplement thereto, or arise out of or are
based upon 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, in each case to the extent, but only to the extent, that such
untrue statement or alleged untrue statement or omission or alleged omission
was made in any preliminary prospectus, any Resale Registration Statement or
any prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Partnership by the Holder
expressly for use therein; and will reimburse the Partnership for any legal or
other expenses reasonably incurred by the Partnership in connection with
investigating or defending any such action or claim as such expenses are
incurred.

(c)           Promptly after receipt by a party
indemnified under subsection (a) or (b) above of notice of the
commencement of any action, such indemnified party shall, if a claim in respect
thereof is to be made against the indemnifying party under such subsection,
notify the indemnifying party in writing of the commencement thereof; but the
omission so to notify the indemnifying party shall not relieve it from any
liability that it may have to any indemnified party otherwise than under such
subsection and shall not relieve the indemnifying party from any liability that
it may have to any indemnified party under this Agreement unless such failure
to give notice actually prejudices the indemnifying party’s ability to defend
the claim.  In case any such action shall
be brought against any indemnified party and it shall notify the indemnifying
party of the commencement thereof, the indemnifying party shall be entitled to
participate therein and, to the extent that it shall wish, to assume the
defense thereof, with counsel satisfactory to such indemnified party (who shall
not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party under such subsection
for any legal expenses of other counsel or any other expenses, in each case
subsequently incurred by such indemnified party, in connection with the defense
thereof other than reasonable costs of investigation.  No indemnifying party shall, without the
written consent of the indemnified party, effect the settlement or compromise
of, or consent to the entry of any judgment with respect to, any pending or
threatened action or claim in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified party is an actual or
potential party to such action or claim) unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party
from all liability arising out of such action or claim and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act, by or on behalf of any indemnified party.

(d)           If the indemnification provided for
in this Section 5 is unavailable to or insufficient to hold harmless an
indemnified party under subsection (a) or (b) above in respect of any
losses, claims, damages or liabilities (or actions in respect thereof) referred
to therein, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified

 8
 

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 benefits received by the
Partnership and by the Holder, respectively, from the transactions contemplated
by this Agreement.  If, however, the
allocation provided by the immediately preceding sentence is not permitted by
applicable law or if the indemnified party failed to give the notice required
under subsection (c) above and such failure actually prejudiced the
indemnifying party’s ability to defend the claim, then each indemnifying party
shall contribute to such amount paid or payable by such indemnified party in
such proportion as is appropriate to reflect not only such relative benefits but
also the relative fault of the Partnership and the Holder in connection with
the statements or omissions that resulted in such losses, claims, damages or
liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations.  The relative
benefits received by the Partnership shall be deemed to include the
proportional value of the assets acquired from the Holder by virtue of the
issuance of the Units to the Holder pursuant to the Contribution and Sale
Agreement, and the relative benefits received by the Holder shall be deemed to
include the profit made by the Holder on the sale of the Units pursuant to the
Resale Registration Statement.  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 Partnership or the Holder and the parties’ relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. 
The Partnership and the Holder agree that it would not be
just or equitable if contributions pursuant to this subsection (d) were
determined by pro rata allocation or by any
other method of allocation that does not take account of the equitable
considerations referred to above in this subsection (d).  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 subsection (d) shall be deemed
to include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim.
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.

(e)           The obligations of the Partnership
under this Section 5 shall be in addition to any liability that the
Partnership may otherwise have and shall extend, upon the same terms and
conditions, to each Person, if any, who controls the Holder within the meaning
of the Securities Act; and the obligations of the Holder under this
Section 5 shall be in addition to any liability that the Holder may
otherwise have and shall extend, upon the same terms and conditions, to each
officer and director of the general partner of the Partnership or its delegate
(including any Person who, with his or her consent, is named in the Resale
Registration Statement as about to become a director of the general partner of
the Partnership or its delegate) and to each Person, if any, who controls the
Partnership or the Corporation within the meaning of the Act.

(f)            For purposes of this Section 5 only,
the term “Resale Registration Statement” shall mean the Resale Registration
Statement as amended at the time it is declared effective by the Commission.

Section 6

such questionnaires and other documents as the Partnership shall reasonably
request in connection with any registration of the resale of the Units pursuant

to an injunction or injunctions to prevent breaches of the provisions of this
Agreement and to enforce specifically the terms of provisions hereof in any
court having jurisdiction, such remedy being in addition to any other remedy to

6.3           Severability.  If any term or provision of this Agreement is
held by a court of competent jurisdiction to be invalid, void or unenforceable,
the remainder of the terms and provisions set forth herein shall remain in full
force and effect and shall in no way be affected, impaired or invalidated, and
the parties hereto shall use their best efforts to find and employ an
alternative means to achieve the same or substantially the same result as that
contemplated by such term or provision.

6.4           Further Assurances.  Subject to the specific terms of this
Agreement, the Holder and the Partnership shall make, execute, acknowledge and
deliver such other instruments and documents, and take all such other actions
as may be reasonably required in order to effectuate the purposes of this
Agreement and to consummate the transactions contemplated hereby.

THIS IS AN AMENDMENT, dated as of April 27,
2007, to that certain PATENT TRANSFER AGREEMENT dated as of May 11, 2005 (the “Patent
Transfer Agreement”) by and between Bayer Schering Pharma AG, a German corporation

Germany (hereinafter referred to as “BSP”) and Acusphere, Inc., a Delaware
corporation having its place of business at 500 Arsenal Street, Watertown, MA
02472, USA (hereinafter referred to as “Acusphere”)

WHEREAS,
BSP (formerly acting under the name Schering Aktiengesellschaft) and Acusphere
entered into the Patent Transfer Agreement on May 11, 2005, pursuant to which
certain patent rights were transferred from BSP to Acusphere;

WHEREAS,
under the Patent Transfer Agreement Acusphere will be obligated to make a final
payment of $3,000,000 to BSP on May 11, 2007;

NOW,
THEREFORE, in consideration of the mutual covenants contained herein the
parties hereto agree as follows:

follows:

a.               $1,500,000
