Dear Ken:

 

This letter confirms our
understanding with respect to your letter agreement with the Company, dated April 13,
2002, as amended on October 14, 2004 (as amended, the “Letter Agreement”).  As you know, the Company is presently in the
process of exploring a restructuring, pursuant to which it is expected that a
significant portion of the Company’s outstanding indebtedness will be
extinguished or materially modified (such transaction is referred to
hereinafter as the “Restructuring”).  The
Board of Directors feels that it is in the best interests of the Company to
retain your services through the consummation of the Restructuring.

 

The Company agrees that,
as a result of any retention by the Company of a chief restructuring officer or
advisor you shall be entitled to terminate your employment, at any time on or
after the date the Restructuring is completed, for “good reason” and that such
termination shall entitle you to the severance protection set forth in the
Letter Agreement (subject to your execution of the release described
therein).  The rights described in the
preceding sentence are in addition to, and are not intended to limit your
existing rights under, the Letter Agreement and, except as set forth herein
this letter does not otherwise modify your rights under such Letter Agreement.

 

Please confirm your
agreement with the foregoing by signing and returning to the undersigned a copy
of this letter.

 

	
   

  	
  Sincerely,

                                 PROMISSORY NOTE

     FOR VALUE RECEIVED, on the Maturity Date, as such term is defined in
Section 1.1 below, ACUSPHERE, INC., a Delaware business corporation with its
chief executive office and principal place of business presently at 500 Arsenal
Street, Watertown, MA 02472 ("BORROWER") promises to pay to the order of
MASSACHUSETTS DEVELOPMENT FINANCE AGENCY, a body politic and corporate created
by Chapter 289 of The Acts of 1998 and established under Massachusetts General
Laws Chapter 23G as amended, ("LENDER") at its principal offices at 160 Federal
Street, Boston, MA 02110, or at such other place as the holder of this note may
from time to time designate in writing, the principal sum of TWO MILLION DOLLARS
($2,000,000.00) or such lesser amount advanced by Lender pursuant to Section 1.1
below, or so much thereof then remaining unpaid, in lawful money of the United
States with interest at the rate or rates set forth below, until fully paid.
Borrower further agrees to pay upon demand made after the occurrence and during
the continuance of an Event of Default, as such term is defined below, all
costs, including reasonable attorneys' fees reasonably incurred in the
collection of Borrower's obligations and the defense, preservation, enforcement
or protection of Lender's rights and remedies under this Note, or in the
foreclosure of any mortgage or security interest now or hereafter securing the
same or in any proceedings to otherwise enforce or protect upon an Event of
Default Lender's rights and remedies under this Note or any security therefor.
Interest on this Note shall be computed on the basis of a year of three hundred
sixty (360) days and actual days elapsed.

     1.0.     FUNDING; TERM; INTEREST RATE; PAYMENTS.

              1.1.    FUNDING; TERM. Borrower may request one (1) advance of up
     to the entire principal amount of this Note upon Lender's receipt from
     Borrower of those documents and satisfaction of those conditions precedent
     specified in that certain letter agreement by and among Borrower and Lender
     dated August 16, 2004 (the "Funding Requirements"), or upon the waiver of
     any such Funding Requirements, as determined in the Lender's sole
     discretion. Provided the Funding Requirements have been satisfied and no
     Event of Default exists on the date Lender receives such request for an
     advance and no event or circumstance exists on such date which with the
     passage time, or notice, or both would result in an Event of Default, the
     Lender shall advance the full requested amount within three (3) business
     days of such date (the "FUND DATE"). The term of this Note shall commence
     on the Fund Date and shall mature on the last day of the 120th calendar
     month following the Fund Date (the "MATURITY DATE").

              1.2.    PAYMENTS OF PRINCIPAL AND INTEREST. No payments shall be
     due and payable during the first twenty-four (24) months of the term of
     this Note (the "DEFERRAL PERIOD"). Thereafter, subject to the adjustment in
     payment provided in Section 1.4 below, payments of principal and interest
     at the rate provided in Section 1.3 below shall be made commencing on the
     first day of the calendar month next following the twenty-five (25) month
     anniversary of the Fund Date (the "PAYMENT START DATE") and continuing on
     the first day of each successive month thereafter through and including the
     Maturity Date at which time all remaining principal and accrued interest
     shall be paid. Each such payment of principal shall be equal to the
     aggregate outstanding Adjusted Principal Amount (hereinafter defined)
     divided by the number of monthly payments then remaining such that the
     Adjusted Principal Amount shall fully amortize over the balance of the term
     of this Note in equal installments. Each such payment of accrued interest
     shall be based on the rate provided in Section 1.3 (or, if applicable,
     Section 1.4) and shall be paid in arrears.

<Page>

              1.3.    INTEREST RATE. So long as no Event of Default (hereafter
     defined) has occurred and is continuing (but subject to applicable cure or
     grace periods), and subject to the terms hereof, the principal outstanding
     hereunder from time to time shall bear interest at the following rates:

              (a) from the Fund Date until the Payment Start Date, representing
     the Deferral Period, simple interest on the outstanding principal amount of
     this Note shall accrue at a rate of five percent (5%) per annum (herein,
     the "ACCRUED INTEREST AMOUNT"); and

              (b) beginning on the Payment Start Date, simple interest on the
     outstanding principal amount of this Note plus the outstanding Accrued
     Interest Amount shall accrue at a rate of five percent (5%) per annum
     (based upon a three hundred and sixty (360) day year and actual days
     elapsed). The sum of the principal of this Note and the Accrued Interest
     Amount at any time then outstanding shall be referred to herein as the
     "ADJUSTED PRINCIPAL AMOUNT."

              1.4.    ADDITIONAL INTEREST AMOUNT, PAYMENT AND ADJUSTMENT TO
     INTEREST RATE.

              (a) Upon the achievement by Borrower of EBITDA (calculated in the
     manner set forth in Section 1.4(c) below) greater than $10,000 during any
     complete twelve-month fiscal year prior to the Maturity Date, an Additional
     Interest Amount, as defined below, shall be calculated in respect of the
     outstanding principal amount of this Note for a period (the "ADDITIONAL
     INTEREST COMPUTATION PERIOD") commencing on the Fund Date and ending on the
     Additional Interest Payment Date (defined below). The "ADDITIONAL INTEREST
     AMOUNT" shall be equal to the difference between (i) the aggregate interest
     amount that would have accrued on the outstanding principal amount of this
     Note during the Additional Interest Computation Period at an annual
     interest rate equal to nine percent (9%) based upon a three hundred and
     sixty (360) day year and actual days elapsed, and (ii) the aggregate amount
     of interest due and payable to Lender hereunder (whether or not paid)
     during the same period pursuant to Sections 1.3 (a) and (b) of this Note.
     The Additional Interest Amount shall be paid to Lender in a lump sum on the
     due date (the "ADDITIONAL INTEREST PAYMENT DATE") of the regularly
     scheduled monthly installment due hereunder next following Borrower's
     receipt of Lender's notice of the sum due as the Additional Interest Amount
     (such notice to be delivered no earlier than publication of the applicable
     audited financial statements as part of Borrower's Annual Report on Form
     10-K and no earlier than ten (10) days prior to any such monthly
     installment date), which Additional Interest Amount shall be paid together
     with such regularly scheduled monthly installment.

              (b) Beginning with the Additional Interest Payment Date and
     continuing thereafter for the remainder of the term of this Note, interest
     on the Adjusted Principal Amount shall accrue and be payable in arrears
     hereunder at the greater of (i) nine percent (9%) per annum, or (ii) the
     current Wall Street Journal consensus Prime Rate as such Prime Rate is
     published in THE WALL STREET JOURNAL ("WSJ") based upon a three hundred and
     sixty (360) day year and actual days elapsed. If, as and when such Prime
     Rate changes, the interest rate charged hereunder shall change accordingly
     without any requirement of prior notice to Borrower. In the event that the
     Prime Rate is no longer published by the WSJ, Lender may, in its sole
     discretion reasonably exercised, select any prime rate then published by
     one (1) of the largest ten banks (measured by total assets) in the United
     States. With each change in the interest rate required by this Section 1.4
     (b), the total installment of principal and interest due and payable
     hereunder shall be modified up or down, as the case may be, provided in
     either event the then outstanding Adjusted Principal Amount will fully
     amortize over the balance of the term of this Note.

                                        2
<Page>

              (c) For purposes of this Note, "EBITDA" shall mean for any
     complete twelve-month fiscal year the sum of (i) net income (or loss) of
     Borrower for such period (excluding extraordinary gains and non-cash gains,
     including without limitation any one-time or lump sum license fees and
     development, milestone or similar payments made by any third party as part
     of a strategic partnership or similar arrangement), plus (ii) all interest
     expense of Borrower for such fiscal year, plus (iii) all charges against
     income of Borrower for such fiscal year for federal, state and local taxes,
     plus (iv) depreciation expenses for such fiscal year, plus (v) amortization
     expenses for such period, all determined in accordance with generally
     accepted accounting principles in the United States of America in effect
     from time to time applied on a consistent basis and with reference to the
     Borrower's audited financial statements with respect to such fiscal year.

     2.0.     DEFAULT RATE. To the extent allowed by applicable law, after the
occurrence of any Event of Default and during the continuation thereof (and
after giving effect to any applicable grace or cure periods), after the Maturity
Date, or after judgment has been rendered on this Note, all outstanding
principal and unpaid interest shall bear, until paid, interest at a rate per
annum equal to five (5%) percentage points greater than that which would
otherwise be applicable assessed retroactive to the date that the Event of
Default first occurs (the "DEFAULT RATE").

     3.0.     LATE CHARGE. If a regularly scheduled payment is ten (10) days or
more late, Borrower will be charged five percent (5%) of the unpaid portion of
the regularly scheduled payment or ten dollars ($10.00), whichever is greater.
If Lender demands payment of this Loan after the occurrence and during the
continuation of an Event of Default (after giving effect to any applicable grace
or cure periods), and Borrower does not pay the Loan within fifteen (15) days
after Lender's demand, Borrower will be charged either five percent (5%) of the
unpaid Adjusted Principal Amount plus accrued unpaid interest or ten dollars
($10.00), whichever is greater.

     4.0.     EXPENSES. Borrower further promises to pay to Lender, as incurred,
and as an additional part of the unpaid Adjusted Principal Amount, upon demand
made after the occurrence and during the continuance of an Event of Default all
costs, expenses and reasonable attorneys' fees reasonably incurred by Lender:
(a) in the protection, modification, collection, defense or enforcement of all
or part of this Note or any guaranty hereof; or (b) in the foreclosure or
enforcement of any mortgage or security interest which may now or hereafter
secure the debt hereunder, or (c) with respect to any action taken to protect,
defend, modify or sustain the lien of any such mortgage or security agreement;
or (d) with respect to any litigation or controversy arising from or connected
with this Note or any mortgage or security agreement or collateral which may now
or hereafter secure this Note; or (e) with respect to any act to protect defend,
modify, enforce or release any of its rights or remedies with regard to, or
otherwise effect collection of, any collateral which may now or in the future
secure this Note or with regard to or against Borrower or any endorser,
guarantor or surety of this Note.

     5.0      OPTIONAL PREPAYMENT. Borrower may at any time elect to prepay the
unpaid amount of this Note, or any part thereof, without penalty or premium;
provided, however, that, notwithstanding anything hereinto the contrary, in the
event that any Additional Interest Amount is due and payable pursuant to Section
1.4 hereof, any such prepayment shall first be applied to (i) the Additional
Interest Amount then owed, then to (i) any unpaid Expenses required by Section
4.0 above, then to (iii) Late Fees, if any is due, then to (iv) Default Rate
interest, if any is due, then to (iv) regularly accrued but unpaid interest
pursuant to Section 1.3 above, and then finally to (v) the Adjusted Principal
Amount.

     6.0.     DEFAULT. The happening of any of the following events or
conditions shall constitute an "EVENT OF DEFAULT" under this Note:

                                        3
<Page>

              6.1.    Failure to make any payment of principal or interest on
     any sum due under this Note within five (5) days after the same shall be
     due and payable.

              6.2.    Failure by Borrower to observe or perform any material
     covenant contained herein or a material default or the occurrence of a
     material event of default in any agreement between Borrower and Lender in
     connection herewith, including that certain Leasehold Mortgage and Security
     Agreement by and between Borrower and Lender of even date herewith (the
     "MORTGAGE") beyond the applicable grace or cure period (or, if no such
     grace or cure period is specified, then beyond thirty (30) days following
     the occurrence of any such default or event of default).

              6.3.    Failure by Borrower to observe or perform any material
     covenant contained in that certain Commercial Building Lease by and between
     Borrower and 890 East LLC ("LANDLORD") of even or near date herewith,
     including all addenda and riders thereto (the "LEASE"), or a material
     default or the occurrence of a material event of default under the Lease
     beyond the applicable grace or cure period. A breach of a "material"
     covenant or a "material" default as provided in this Section 6.3 or 6.2
     above mean any breach and/or default of any covenant, term or condition of
     the Lease, this Note, the Mortgage, or other agreement between Borrower and
     Lender which in the Lender's good faith reasonable belief evidences an
     unacceptable decline in the Borrower's ability to fully perform its
     obligations under this Note.

              6.4     Failure of Borrower to exercise its option to extend the
     original term of the Lease for an additional five (5) years pursuant to and
     in accordance with the terms of Section 4 of the Lease, prior the
     expiration of the original term of the Lease.

              6.5.    Any representation or warranty made by Borrower herein or
     in any agreement executed in connection herewith, including the Mortgage,
     or any statement, certificate or other data furnished by Borrower in
     connection herewith or with such agreements, proves at any time to be
     incorrect in any material respect.

              6.6.    A judgment or judgments for the payment of money shall be
     rendered against Borrower in an amount, individually or in the aggregate,
     of at least two hundred fifty thousand dollars ($250,000.00), and any such
     judgment shall remain unsatisfied and in effect for any period of thirty
     (30) consecutive days without a stay of execution, and the Lender holds the
     good faith belief that such unsatisfied judgment or unstayed execution is
     materially adverse to the condition (financial or otherwise) of the
     Borrower or the Lender's collateral for this Note.

              6.7.    Borrower shall: (a) apply for or consent to the
     appointment of a receiver, trustee or liquidator of all or a substantial
     part of any of its assets; (b) admit in writing its inability to pay its
     debts as they mature; (c) file or permit the filing of any petition, case
     arrangement, reorganization, or the like under any insolvency or bankruptcy
     law, or the adjudication of it as a bankrupt, or the making of an
     assignment for the benefit of creditors or the consenting to any form or
     arrangement for the satisfaction, settlement or delay of debt or the
     appointment of a receiver for all or any part of its properties; or (d) any
     action shall be taken by Borrower for the purpose of effecting any of the
     foregoing.

              6.8.    An order, judgment or decree shall be entered, or a case
     shall be commenced, against Borrower, without its application, approval or
     consent by any court of competent jurisdiction, approving a petition or
     permitting the commencement of a case seeking reorganization or liquidation
     of Borrower or appointing a receiver, trustee or liquidator of Borrower, or
     of all or a substantial part of the assets of Borrower, and Borrower, by
     any act,

                                        4
<Page>

     indicates its approval thereof, consent thereto, or acquiescence therein,
     or such order, judgment, decree or case shall continue unstayed and in
     effect for any period of sixty (60) consecutive days, or an order for
     relief in connection therewith shall be entered.

              6.9.    If Borrower shall dissolve or liquidate, or be dissolved
     or liquidated, or cease to legally exist, or merge or consolidate, or be
     merged or consolidated with or into any other corporation or entity.

              6.10.   Failure by Borrower to pay any other indebtedness or
     obligation, or if any such other indebtedness or obligation shall be
     accelerated, or if there exists any event of default under any instrument,
     document or agreement governing, evidencing or securing such other
     indebtedness or obligation, in any event, in an amount, individually or in
     the aggregate, of at least two hundred fifty thousand dollars
     ($250,000.00); and any such amount remains unpaid or any such indebtedness
     or obligations remain accelerated or any such event of default remains
     uncured, in each case, for any period of thirty (30) consecutive days; and
     the Lender holds the good faith belief that such unpaid indebtedness or
     event of default is materially adverse to the condition (financial or
     otherwise) of the Borrower or the Lender's collateral for this Note.

              Upon and after an Event of Default, the whole of said
indebtedness, both principal and interest, and including any other sums which
may become due under this Note, shall, at the option of the holder of this Note,
immediately become due and payable without presentment, demand, protest, notice
of protest, or other notice of dishonor of any kind, all of which are hereby
expressly waived by Borrower.

     7.0.     MAXIMUM PERMISSIBLE INTEREST RATE. Borrower shall not be obligated
to pay and Lender shall not collect interest at a rate higher than the maximum
permitted by law or the maximum that will not subject Lender to any civil or
criminal penalties. If, because of the acceleration of maturity the payment of
interest in advance or any other reason, Borrower is required, under the
provisions hereof, pursuant to the provisions of any other agreements,
instruments, documents, security agreements, mortgages, financing statements,
and supplements thereto and relating to the Loan, or entered into between
Borrower in favor of, or with, Lender, at any time, for any purpose (the "LOAN
DOCUMENTS") or otherwise, to pay interest at a rate in excess of such maximum
rate, the rate of interest under such provisions shall immediately and
automatically be reduced to such maximum rate and any payment made in excess of
such maximum rate shall be applied to principal outstanding hereunder or, if
received by applicable law, shall be returned to Borrower.

     8.0.     [RESERVED].

     9.0.     REPLACEMENT DOCUMENTS. Upon receipt of an affidavit of an officer
of Lender as to the loss, theft, destruction or mutilation of the Note or any
other security document(s), together with an agreement reasonably satisfactory
to the Borrower to indemnify the Borrower from any loss incurred by it in
connection therewith, and, in the case of any such loss, theft, destruction or
mutilation, upon surrender and cancellation of such Note or other document(s),
Borrower will issue, in lieu thereof, a replacement Note or other document(s) in
the same principal amount thereof and otherwise of like tenor.

     10.0     COMMITMENT LETTER. This Note contains the entire understanding of
the parties with respect to the matters contained herein and supercedes all
prior understandings and writings related thereto (including without limitation
that certain Commitment Letter executed by Lender and Borrower and dated May 12,
2004, which is superceded by this Note).

     11.0.    CONSENT TO JURISDICTION. Borrower hereby agrees that any state or
local court of the Commonwealth of Massachusetts or any United States District
Court for the District of Massachusetts or,

                                        5

equitable proceedings and which has subject matter jurisdiction over the matter
in controversy, shall have exclusive jurisdiction to hear and determine any
claims or disputes between Borrower and Lender pertaining directly or indirectly
to this Note or to any matter arising in connection with this Note.

     12.0.    WAIVERS. Borrower agrees that no delay or failure on the part of
the holder in exercising any power, privilege, remedy, option or right hereunder
shall operate as a waiver thereof or of any other power, privilege, remedy or
right; nor shall any single or partial exercise of any power, privilege, remedy,
option or right hereunder preclude any other or future exercise thereof or the
exercise of any other power, privilege, remedy, option or right. The rights and
remedies expressed herein are cumulative, and may be enforced successively,
alternately, or concurrently and are not exclusive of any rights or remedies
which holder may or would otherwise have under the provisions of all applicable
laws, and under the provisions of all agreements between Borrower and Lender.

     Borrower hereby waives presentment, demand, notice, protest and all other
demands and notices in connection with the delivery, acceptance, performance,
default or enforcement of this Note. Borrower hereby assents to any extension or
postponement of the time of payment or any other indulgence, to the addition or
release of any party or person primarily or secondarily liable, and to the
addition, release and/or substitution of all or any portion of any collateral
now or hereafter securing this Note.

     BORROWER AND LENDER MUTUALLY HEREBY KNOWINGLY, VOLUNTARILY AND
INTENTIONALLY WAIVE THE RIGHT TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM BASED
HEREON, ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS NOTE OR ANY OTHER
