COVENANTS

Micromet's affirmative covenants under the 2007 Securities Purchase Agreement
include obligations related to 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 "Trading 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, as
amended (the "Securities Act").

REGISTRATION RIGHTS

Micromet has agreed, pursuant to that certain Registration Rights Agreement
dated as of June 19, 2007 by and among the Issuer, the NGN Biomed Entities and
the investors set forth therein (the "2007 Registration Rights Agreement"), to
prepare and file within 30 days of June 19, 2007 (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 best
efforts to cause the registration statement to be declared effective under the
Securities Act on or prior to (i) the 90th calendar day following June 19, 2007,
or (ii) if the registration statement receives Commission review, the 150th
calendar day after June 19, 2007 (the "Effectiveness Date"). The Company shall
use its best 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 partial
liquidated damages and not as a penalty, equal to one percent (1.5%) of the
aggregate purchase price paid by each investor pursuant to the 2007 Securities
Purchase Agreement for any unregistered Initial Shares (as defined below) then
held by such investor; provided, however, that the total amount of such payments
to each investor shall not exceed, when aggregated with all such payments paid
to such investor, twelve percent (12%) of the aggregate purchase price paid by
such investor pursuant to the 2007 Securities Purchase Agreement. 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 within seven days after the date payable, such Event Payments
shall bear interest at the rate of eighteen percent (18.0%) per annum accruing
daily from the date such partial liquidated damages are due until such amounts,
plus all such interest thereon, are 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 initial registration statement filed pursuant to the 2007
Registration Rights Agreement (the "Initial Registration Statement") is not
filed on or prior to its Filing Date (if the Issuer files the Initial
Registration Statement without affording the holders the opportunity to review
and comment on the same as required by Section 3(a) of the 2007 Registration
Rights Agreement, the Issuer shall be deemed to have not satisfied this clause
(i)), or (ii) the Issuer fails to file with the Commission a request for
acceleration of a registration statement in accordance with Rule 461 promulgated
by the Commission pursuant to the Securities Act, within five trading days of
the date that the Issuer is notified (orally or in writing, whichever is
earlier) by the Commission that such registration statement will not be
"reviewed" or will not be subject to further review, or (iii) as to, in the
aggregate among all holders on a pro-rata basis based on their purchase of the
securities pursuant to the 2007 Securities Purchase Agreement, a registration
statement registering for resale all of the Initial Shares is not declared
effective by the Commission by the Effectiveness Date of the Initial
Registration Statement, or (iv) after the effective date of a registration
statement, such registration statement ceases for any reason to remain
continuously effective as to all registrable securities included in such
registration statement, or the holders are otherwise not permitted to utilize
the prospectus therein to resell such registrable securities, for more than 10
consecutive calendar days or more than an aggregate of 15 calendar days (which
need not be consecutive calendar days) during any 12-month period. "Initial
Shares" means a number of registrable securities equal to the lesser of (i) the
total number of registrable securities and (ii) one-third of the number of
issued and outstanding shares of Common Stock that are held by non-affiliates of
the Issuer on the day immediately prior to the Closing.

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 Amendment No. 1, NGN Biomed Opportunity I is the
record holder of 1,816,935 shares of Common Stock and Warrants to purchase
586,024 shares of Common Stock (the "NGN Biomed Opportunity I Shares") and NGN
Biomed Opportunity I GmbH is the record holder of 1,313,552 shares of Common
Stock and Warrants to purchase 423,665 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 as 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. As of the date of this
Amendment No.1, NGN Biomed Opportunity I and NGN Biomed Opportunity I GmbH are
prohibited from purchasing the shares of Common Stock issuable upon exercise of
the Warrants because the Warrants prohibit the exercise of any portion of the
Warrant to the extent that after giving effect to such issuance, the warrant
holder (together with its affiliates, and any other person or entity acting as a
group together with the warrant holder or any of the its affiliates), would
beneficially own in excess 4.99% of the number of shares of the Common Stock
outstanding immediately after giving effect to the issuance of shares of Common
Stock issuable upon exercise of this Warrant. As a result of this prohibition,
each of the Reporting Persons may be deemed to share the power to direct the
disposition and vote an aggregate of 3,130,487 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 8.9% of the Common Stock outstanding,
based upon 31,504,065 shares of Common Stock reported by the Issuer to be
outstanding as of April 30, 2007 in a Definitive Proxy Statement filed on April
30, 2007 and the issuance of the securities pursuant to the 2007 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.

       (e) Not applicable.


Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to
--------------------------------------------------------------------------------
Securities of the Issuer

transactions described in this Amendment No. 1 and the Securities Purchase
Agreement, the Warrants and the transactions described in the Statement on
Schedule 13D filed with the Commission on August 3, 2006, none of the Reporting
Persons have any contract, arrangement, understanding or relationship (legal or
otherwise) with any other person with respect to any securities of the Issuer,
