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

COVENANTS

Micromet's affirmative covenants under the Securities Purchase Agreement include
obligations related to providing the NGN Entities with a right of first refusal
on certain future issuances of securities by Micromet during the one year period
following the closing; listing, and maintenance of such listing, of its common
stock on the New York Stock Exchange, Nasdaq Global Market, Nasdaq Capital
Market or the American Stock Exchange (each an "Eligible Market"); removing the
legends on the certificates representing the shares purchased by the investors
(subject to liquidated damages if such removal is delayed); and providing
information required by Rule 144 under the Securities Act of 1933.

REGISTRATION RIGHTS

Micromet has agreed, pursuant to the Securities Purchase Agreement, to prepare
and file within 45 days of closing (the "Filing Date") a registration statement
with the Commission covering the resale of all of the shares of common stock
issued pursuant to the Securities Purchase Agreement and upon exercise of the
Warrants (the "Registrable Securities") for an offering to be made on a
continuous basis pursuant to Rule 415. Micromet shall use its commercially
efforts to cause the registration statement to be declared effective under the
Securities Act on or prior to (i) the 75th calendar day following July 24, 2006,
or (ii) if the registration statement receives Commission review, the 135th
calendar day after July 24, 2006 (the "Required Effective Date"). The Company
shall use its commercially reasonable efforts to keep such registration
statement continuously effective under the Securities Act until all Registrable
Securities covered by such registration statement have been sold or may be sold
without volume restrictions pursuant to Rule 144(k) (the "Effectiveness
Period").

Should an Event (as defined below) occur, then upon the occurrence of such
Event, and on every monthly anniversary thereof until the applicable Event is
cured, the Company shall pay to each investor an amount in cash, as liquidated
damages and not as a penalty, equal to one percent (1.0%) of (i) the number of
shares of Common Stock held by such investor as of the date of such Event,
multiplied by (ii) the purchase price paid by such investor for such Common
Stock then held; provided, however, that the total amount of such payments shall
not exceed, when aggregated with all such payments paid to all investors, ten
percent (10%) of the aggregate purchase price. Such payments to which an
investor shall be entitled are referred to herein as "Event Payments." Any Event
Payments shall apply on a pro rated basis for any portion of a month prior to
the cure of an Event. In the event the Company fails to make Event Payments in a
timely manner, such Event Payments shall bear interest at the rate of one
percent (1.0%) per month (prorated for partial months) until paid in full. All
pro rated calculations made pursuant to this paragraph shall be based upon the
actual number of days in such pro rated month. For such purposes, each of the
following shall constitute an "Event": (i) the registration statement is not
filed on or prior to the Filing Date or is not declared effective on or prior to
the Required Effectiveness Date; (ii) except as provided for in Section 6.1(e)
of the Securities Purchase Agreement (the "Excluded Events"), after the
Effective Date, an investor is not permitted to sell Registrable Securities
under the Registration Statement (or a subsequent registration statement filed
in replacement thereof) for any reason (other than the fault of such investor)
for five or more Trading Days (whether or not consecutive); (iii) except as a
result of the Excluded Events, the Common Stock is not listed or quoted, or is
suspended from trading, on an Eligible Market for a period of three trading days
(which need not be consecutive trading days) during the Effectiveness Period;
(iv) with respect to an investor, the Company fails for any reason to deliver a
certificate evidencing any securities to such investor within five trading days
after delivery of such certificate is required pursuant to any transaction
document or the exercise rights of the investors pursuant to the Warrants are
otherwise suspended for any reason; or (v) during the Effectiveness Period,
except as a result of the Excluded Events, the Company fails to have any Shares
listed on an Eligible Market.

Except as set forth in this Item 4, the Reporting Persons have no plans or
proposals that relate to or that would result in any of the actions or
transactions described in paragraphs (a) through (j) of Item 4 of the
instructions to Schedule 13D. However, the Reporting Persons reserve the right
from time to time to formulate plans or proposals regarding the Issuer or any of
its securities and to carry out any of the actions or transactions described in
paragraphs (a) through (j) of Item 4 of the instructions to Schedule 13D, to the
extent they deem advisable.

Item 5. Interest in Securities of the Issuer.
---------------------------------------------
(a) (b) As of the date of this Statement, NGN Biomed Opportunity I is the record
holder of 1,289,778 shares of Common Stock and a Warrant to purchase 322,445
shares of Common Stock (the "NGN Biomed Opportunity I Shares") and NGN Biomed
Opportunity I GmbH is the record holder of 932,444 shares of Common Stock and a
Warrant to purchase 233,111 shares of Common Stock (the "NGN Biomed Opportunity
I GmbH Shares"). As sole general partner of NGN Biomed Opportunity I, NGN GP
along with NGN Capital, the sole general partner of NGN GP, may be deemed to
beneficially own the NGN Biomed Opportunity I Shares. As the sole managing
limited partner of NGN Biomed Opportunity I GmbH, NGN Capital may be deemed to
beneficially own the NGN Biomed Opportunity I GmbH Shares. By virtue of the
relationship among NGN Biomed Opportunity I, NGN Biomed Opportunity I GmbH, NGN
GP and NGN Capital, each of the Reporting Persons may be deemed to share the
power to direct the disposition and vote of the NGN Biomed Opportunity I Shares
and the NGN Biomed Opportunity I GmbH Shares, for an aggregate of 2,222,222
shares of Common Stock and Warrants to purchase 555,556 shares of Common Stock
(together, the "Record Shares"). The Reporting Persons expressly disclaim
membership in a "group" as used in Rule 13d-1(b)(ii)(J). Each Reporting Person
also expressly disclaims beneficial ownership of any shares of Common Stock of
the Issuer, except for the shares, if any, such Reporting Person holds of
record.

The Record Shares represent approximately 8.7% of the Common Stock outstanding,
based upon 29,190,810 shares of Common Stock reported by the Issuer to be
outstanding as of July 24, 2006 in a Current Report on Form 8-K filed on July
26, 2006 and the issuance of the Record Shares pursuant to the Securities
Purchase Agreement.

       (c) None of the Reporting Persons has effected any transactions in the
           shares of Common Stock in the past sixty days, other than the
           transactions described herein.

       (d) Not applicable.

Except for the Securities Purchase Agreement and the Warrants and the
transactions described in this Schedule, none of the Reporting Persons have any
contract, arrangement, understanding or relationship (legal or otherwise) with
