information within the possession of the Buyer and necessary for such sale.

5.7 Registration Statement.

(a) Filing. On or before the seventy-fifth (75th) day following the Closing
Date, the Buyer shall prepare and file with the SEC a Registration Statement on Form S-3 (or, if
the Buyer is not then eligible to use Form S-3, such other form that is then available to the Buyer
for resales of its securities) as a “shelf” registration statement under Rule 415 covering the
resale of the maximum number of Registrable Securities permitted to be included in such
Registration Statement pursuant to any Governmental Requirement. The Registration Statement shall
state, to the extent permitted by Rule 416 under the Securities Act, that it also covers such
indeterminate number of additional shares of Ener1 Common Stock as may become issuable upon
exercise of the Warrants in order to prevent dilution resulting from stock splits, stock dividends
or similar events.

(b) Effectiveness. The Buyer shall use commercially reasonable efforts to cause the
Registration Statement to become effective on or before the forty-fifth (45th) day
following the filing thereof. The Buyer shall respond promptly to any and all comments made by the
staff of the SEC on the Registration Statement, and shall submit to the SEC, within three (3)
Business Days after the Buyer learns that no review of the Registration Statement will be made by
the staff of the SEC or that the staff of the SEC has no further comments on a Registration
Statement, as the case may be, a request for acceleration of the effectiveness of such Registration
Statement to a time and date not later than three (3) Business Days after the submission of such
request. The Buyer will maintain the effectiveness of the Registration Statement during the period

later of (i) the date on which no Purchase Price Shares or Warrant Shares (assuming cashless
exercise of the Warrant(s)) constitute Registrable Securities or (ii) the one-year anniversary of
the date on which the Registration Statement is declared effective (the “Registration Period”).

(c) Piggyback Registration. If at any time prior to the second anniversary of the
Closing Date, (i) the Buyer proposes to register shares of Ener1 Common Stock under the Securities
Act in connection with the public offering of such shares for cash (a “Proposed Registration”)
other than a registration statement on Form S-8 or Form S-4 or any successor or other forms
promulgated for similar purposes and (ii) a Registration Statement covering the sale of all of the
Registrable Securities is not then effective and available for sales thereof by the holders of
Warrants or Registrable Securities (each, a “Holder” and, collectively, the “Holders”), the Buyer
shall, at such time, promptly give each Holder written notice of such Proposed Registration. Each
Holder shall have ten (10) Business Days from its receipt of such notice to deliver to the Buyer a
written request specifying the amount of Registrable Securities that such Holder intends to sell
and such Holder’s intended method of distribution. Upon receipt of such request, the Buyer shall
use commercially reasonable efforts to cause all Registrable Securities which the Buyer has been
requested to register to be registered under the Securities Act to the extent necessary to permit
their sale or other disposition in accordance with the intended methods of distribution specified
in the request of such Holder; provided, however, that the Buyer shall have the right to postpone
or withdraw any registration effected pursuant to the terms hereof without obligation to the
Holders. In connection with any registered offering undertaken by the Buyer or by security
holders of the Buyer, if the managing underwriter(s) thereof, in the case of an underwritten
offering, shall request a limitation on the number of shares of Ener1 Common Stock which may be
included in a registration statement because, in the judgment of such underwriter(s), marketing,
regulatory or other factors dictate such limitation is necessary to facilitate such offering or, if
the number of shares to be included on such registration statement is limited by applicable law or
regulation, then the Buyer shall be obligated to include in the registration statement only such
amount of Registrable Securities with respect to which each Holder has requested inclusion
hereunder as such underwriter(s) shall permit, in the case of an underwritten offering, or as may
be lawfully included on such registration statement, where such amount is limited by law or
regulation. Any exclusion of Registrable Securities shall be made pro rata among the Holders
seeking to include Registrable Securities in a registration statement, in proportion to the number
of Registrable Securities sought to be included by such Holders; provided, however, that the Buyer
shall not exclude any Registrable Securities unless the Buyer has first excluded all outstanding
securities, the holders of which are not entitled to inclusion of such securities in the
registration statement or are not entitled to pro rata inclusion with the Registrable Securities;
and provided, further, that, after giving effect to the immediately preceding proviso, any
exclusion of Registrable Securities shall be made pro rata with holders of other securities having
the right to include such securities in the registration statement.

(d) Additional Registration Obligations of the Buyer. In connection with the
registration of Registrable Securities hereunder, the Buyer shall:

(i) notify each Holder, as promptly as practicable, of the effectiveness of the
Registration Statement;

(ii) use commercially reasonable efforts to prepare and file with the SEC such
amendments and supplements to the Registration Statement and the prospectus used in
connection with the Registration Statement as may be necessary to comply with the provisions
of the Securities Act or to maintain the effectiveness of the Registration Statement during
the Registration Period, or as may be reasonably requested by a Holder in order to
incorporate information concerning such Holder or such Holder’s intended method of
distribution;

(iii) prior to or as promptly as practicable following the Closing, use commercially
reasonable efforts to secure the listing of all Registrable Securities on the American Stock
Exchange (or such other principal exchange on which the Ener1 Common Stock is then listed);

(iv) furnish to each Holder such number of copies of the prospectus included in the
Registration Statement as such Holder may reasonably request in order to facilitate the
disposition of such Holder’s Registrable Securities;

(v) notify each Holder immediately after becoming aware of the occurrence of any event
as a result of which the prospectus included in the Registration Statement, as then in
effect, contains an untrue statement of material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not misleading in
light of the circumstances then existing (a “Disclosure Triggering Event”), and as promptly
as practicable thereafter prepare and file with the SEC a supplement or an amendment to, or
document to be incorporated into, such prospectus as may be necessary so that such
prospectus does not contain an untrue statement of material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein not
misleading in light of the circumstances then existing;

(vi) provide to each Holder and its representatives the reasonable opportunity to
conduct, subject to confidentiality agreements reasonably acceptable to the Buyer, a
reasonable inquiry of the Buyer’s financial and other records during normal business hours
and make available its officers, directors and employees for questions regarding information
which such Holder may reasonably request in order to fulfill any due diligence obligation on
its part;

(vii) use commercially reasonable to register or qualify the Registrable Securities
covered by the Registration Statement under the Securities Laws of such jurisdictions in the
United States as shall be reasonably requested by a Holder; provided, however, that the
Buyer shall not be required in connection therewith or as a condition thereto to qualify to
do business or to file a general consent to service of process in any such jurisdiction;

(viii) in the event of any underwritten public offering by the Buyer, enter into and
perform its obligations under an underwriting agreement (which agreement shall be in a form
customary for similar underwritten public offerings) with terms reasonably satisfactory to
the managing underwriter of such offering, and participate in customary “road show”
presentations;

(ix) maintain a transfer agent and registrar and a CUSIP number for the Ener1 Common
Stock; and

(x) bear all expenses, other than underwriting discounts and commissions and fees and
expenses of counsel and other advisors to the Holders, incurred by the Buyer in connection
with the filings, registrations and qualifications described in paragraphs (a) through (d)
of this Section 5.7, including (without limitation) all registration, filing and
qualification fees, printers’ and accounting fees, and the fees and disbursements of counsel
for the Buyer.

(e) Obligations of each Holder. In connection with the registration of Registrable
Securities hereunder, and as a condition to the Buyer’s obligations under this Section 5.7, each
Holder shall:

(i) timely furnish to the Buyer in writing such information regarding itself and the
intended method of disposition of such Registrable Securities as the Buyer shall reasonably
request in order to effect the registration thereof;

(ii) upon receipt of written notice from the Buyer of the occurrence of a Disclosure
Triggering Event, immediately discontinue any sale or other disposition of such Registrable
Securities pursuant to such Registration Statement until such Holder has received notice
from the Buyer that such Disclosure Trigger Event no longer exists; provided, that (A) such
notice from the Buyer shall not effect any sale executed by a Holder prior to such Holder’s
receipt of such notice and (B) Buyer shall not engage in any transaction or activity which
would constitute or result in a Disclosure Triggering Event to the extent such Disclosure
Triggering Event would prevent any Holder from disposing of Registrable Securities for more
than ninety (90) days in any 12-month period;

(iii) to the extent required by applicable law, deliver a prospectus to the purchaser
of such Registrable Securities; and

(iv) notify the Buyer when it has sold, distributed or otherwise transferred all of the
Registrable Securities held by it pursuant to either the Registration Statement or Rule 144.

(f) Indemnification. In the event any Registrable Securities are included in a
Registration Statement under this Section 5.7:

(i) To the extent permitted by law, the Buyer shall indemnify and hold harmless each
Holder, the officers, directors and partners of each Holder, and each person, if any, who
controls such Holder within the meaning of the Securities Act or the Exchange Act, against
any losses, claims, damages, or liabilities (joint or several) to which they may become
subject under the Securities Act, the Exchange Act or other federal or state law, insofar as
such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or
are based upon any of the following statements, omissions or violations (collectively a
“Violation”): (i) any untrue statement or alleged untrue statement of a material fact
contained in any Registration Statement, including any preliminary prospectus or final
prospectus contained therein or any amendments or supplements thereto; or (ii) 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 the Buyer will reimburse each
such Holder, officer, director or partner, underwriter or controlling person for any legal
or other expenses reasonably incurred by them, as incurred, in connection with investigating
or defending any such loss, claim, damage, liability, or action; provided,
however, that the Buyer’s indemnity contained in this Section 5.7(f)(i) shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability or action if
such settlement is effected without the consent of the Buyer (which consent shall not be
unreasonably withheld), nor shall the Buyer be liable in any such case for any such loss,
claim, damage, liability, or action to the extent that it arises out of or is based upon a
Violation which occurs in reliance upon and in conformity with written information furnished
in writing and expressly stated for use in connection with such registration by such Holder
or any person acting on such Holder’s behalf.

(ii) To the extent permitted by law, each Holder whose Registrable Securities are
included for resale on the Registration Statement will indemnify and hold harmless the
Buyer, each of its directors, each of its officers who have signed the Registration
Statement, each person, if any, who controls the Buyer within the meaning of the Securities
Act, against any losses, claims, damages or liabilities (joint or several) to which any of
the foregoing persons may become subject, under the Securities Act, the Exchange Act or
other federal or state law, insofar as such losses, claims, damages, or liabilities (or
actions in respect thereto) arise out of or are based upon any Violation, in each case to
the extent (and only to the extent) that such Violation occurs in reliance upon and in
conformity with written information furnished by such Holder expressly stated in a writing
for use in connection with such registration; and each such Holder will reimburse any legal
or other expenses, as incurred, where such expenses are reasonably incurred by any person
intended to be indemnified pursuant to this Section 5.7(f)(ii), in connection with
investigating or defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement contained in this Section
5.7(f)(ii) shall not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of the Holder, which
consent shall not be unreasonably withheld. Notwithstanding the foregoing, the liability of
each Holder under this Section 5.7(f)(ii) shall be limited to an amount equal to the net
proceeds received by such Holder with respect to the shares sold by such Holder pursuant to
the Registration Statement.

(iii) Promptly after receipt by an indemnified party under this Section 5.7(f) of
notice of the commencement of any action (including any governmental action), such
indemnified party will, if a claim in respect thereof is to be made against any indemnifying
party under this Section 5.7(f), notify the indemnifying party in writing of the
commencement thereof, and the indemnifying party shall have the right to participate in and,
to the extent the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the
parties; provided, however, that an indemnified party shall have the right
to retain its own counsel, with the reasonable fees and expenses to be paid by the
indemnifying party (subject to the last sentence of Section 5.7(f)(ii)) if the indemnified
party reasonably determines that representation of such indemnified party by the counsel
retained by the indemnifying party would be inappropriate due to actual or potential
conflicts between such indemnified party and any other party represented by such counsel in
such proceeding. The failure to notify an indemnifying party within a reasonable time of the
commencement of any such action, to the extent prejudicial to its ability to defend such
action, shall relieve such indemnifying party of any liability to the indemnified party
under this Section 5.7(f), but the omission so to notify the indemnifying party will not
relieve it of any liability that it may have to any indemnified party otherwise than under
this Section 5.7(f).

(iv) If the indemnification provided for in this Section 5.7(f) is held by a court of
competent jurisdiction to be unavailable to an indemnified party with respect to any losses,
claims, damages or liabilities referred to herein, the indemnifying party, in lieu of
indemnifying such indemnified party thereunder, shall to the extent permitted by applicable
law contribute to the amount paid or payable by such indemnified party as a result of such
loss, claim, damage or liability in such proportion as is appropriate to reflect the
relative fault of the indemnifying party, on the one hand, and of the indemnified party, on
the other, in connection with that which resulted in such loss, claim, damage or liability,
as well as any other relevant equitable considerations. The relative fault of the
indemnifying party and of the indemnified party shall be determined by a court of law by
reference to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission to state a material fact relates to information supplied by
the indemnifying party or by the indemnified party and the parties’ relative intent,
provided that in no event shall any contribution by a Holder pursuant to this Section
5.7(f)(iv) exceed the net proceeds received by such Holder with respect to the shares sold
by such Holder pursuant to the Registration Statement.

(v) The obligations of the Buyer and Holders under this Section 5.7(f) shall survive
the completion of any offering of Registrable Securities pursuant to a Registration
Statement under this Section 5.7.

(g) Assignment of Registration Rights. The rights to cause the Buyer to register the
resale of Registrable Securities pursuant to this Section 5.7 may be assigned by a Holder to a
transferee or assignee of Registrable Securities; provided, however, that such assignment shall be
effective only if immediately following such transfer the Buyer is given written notice thereof,
the transferee agrees in writing to be bound by the terms and conditions of this Agreement and such
transfer complies with the terms of this Agreement.

5.8 Legend. The Sellers acknowledge and agree that the certificates representing the
Securities may bear at issuance a restrictive legend in substantially the following form:

“The securities represented by this certificate have not been registered under the
Securities Act of 1933, as amended (the “Securities Act”), or the securities laws of
any state, and may not be offered or sold unless a registration statement under the
Securities Act and applicable state securities laws shall have become effective with
regard thereto, or an exemption from registration under the Securities Act and
applicable state securities laws is available in connection with such offer or
sale.”

Notwithstanding the foregoing, it is agreed that, if Securities have been sold pursuant to an
effective registration statement or pursuant to Rule 144, subject in the case of a sale pursuant to
Rule 144 to receipt by the Buyer of customary documentation reasonably satisfactory to the Buyer
and its legal counsel in connection therewith, such Securities shall be issued without any legend
or other restrictive language and, with respect to Securities upon which such legend is stamped,
the Buyer shall issue new certificates without such legend to the Holder upon request.

5.9 Limitations on Disposition. Each Seller agrees that it shall not sell, transfer,
assign or otherwise dispose of any Securities, unless:

(a) such proposed disposition is made pursuant to an effective Registration Statement under
the Securities Act and complies with the plan of distribution contained therein;

(b) if such proposed disposition is to a Person that owns or operates (i) a hedge fund or
substantially similar investment vehicle or (ii) a business that competes directly with the
Business, such Seller has delivered written notice thereof to the Buyer specifying the material
terms of such disposition and offering such Securities to the Buyer upon the same terms specified
in such notice; upon receipt of such notice, the Buyer shall have five (5) Business Days in which
to notify such Seller that it wishes to purchase all (but not less than all) of such Securities
upon such terms; in the event that the Buyer either does not respond to such notice within such
five Business Day period or declines in writing to purchase such Securities, such Seller may sell
such Securities to such Person upon the same terms specified in such notice (it being understood
that if such terms are amended or modified in any material respect so that they are less favorable
to such Seller, such Seller must reoffer such Securities to the Buyer in accordance with this
subparagraph (b) on such amended or modified terms prior to selling them to such Person);

(c) if such proposed disposition is made pursuant to an exemption from registration under the
Securities Act (other than pursuant to Rule 144), such Seller has furnished the Buyer with an
opinion of counsel, reasonably satisfactory to the Buyer, that such disposition will not require
registration of such Securities under the Securities Act; and

(d) if such proposed disposition is made pursuant to Rule 144, such Seller has furnished the
Buyer with documentation reasonably satisfactory to the Buyer and its legal counsel that the
proposed transaction satisfies the requirements of Rule 144.

5.10 Purchase of Minority Shares. For the avoidance of doubt, the Buyer acknowledges
and agrees that the Sellers shall have no liability or obligation in connection with the election
by the Institutional Shareholders to exercise the co-sale rights referred to in Section 5.1(a),
and will be indemnified and held harmless by the Buyer with respect thereto.

5.11 Name Change. Within one hundred and twenty (120) days after the Closing Date,
the Buyer shall change the names of the TVG Entities to remove “TVG” or any portion thereof from
such names.

5.12 Update of Disclosure Schedules. From time to time prior to the Closing, the
Sellers may supplement or amend the Schedules referred to in Section 3 solely for the purpose of
providing disclosure with respect to matters relating to the Enertech Subsidiary as long as such
matters have not had or would not be reasonably likely to have a Material Adverse Effect on
Enertech. The representations and warranties of the Sellers hereunder as of the date hereof and as
of the Closing Date shall be deemed to be made with and after giving effect to all such
supplements and amendments.

to the Closing:

(a) by the mutual written agreement of the Sellers and the Buyer;

(b) by the Sellers or the Buyer, if the Closing has not occurred on or prior to October 31,
2008; provided, however, that the right to terminate this Agreement pursuant to this Section 7.1(b)
may not be exercised by a Party whose failure to perform or fulfill any of its obligations
hereunder has been the cause of, or resulted in, the failure of the Closing to occur on or before
such date;

(c) by the Sellers or the Buyer, if there shall be in effect any (i) final, non-appealable
injunction or binding order of any court or other tribunal having jurisdiction over either Seller,

(d) by the Buyer, upon breach in any material respect of any material representation, warranty

either case such that the conditions set forth in Section 6.1 would not be satisfied; or

(e) by the Sellers, upon breach in any material respect of any material representation,
warranty or covenant on the part of the Buyer set forth in this Agreement, or if any representation

9. INDEMNIFICATION.

9.1 Indemnification by the Sellers.

(a) Indemnification Obligations. Subject to the provisions of Sections 9.1(b), 9.4
and 10.14 below, from and after the Closing, each Seller agrees, jointly and severally, to
indemnify and hold the Buyer and its subsidiaries and Affiliates and persons serving as officers,
directors, members, attorneys, stockholders, partners or employees thereof (collectively the “Buyer
Indemnified Parties”) harmless from and against any actual out-of-pocket damages, liabilities,
losses, taxes, fines, penalties, costs, and expenses (including, without limitation, reasonable
fees and expenses of counsel) of any kind or nature whatsoever (whether or not arising out of
third-party claims and including all reasonable amounts, paid in investigation, defense or
settlement of the foregoing), other than consequential, speculative, punitive or similar damages or
losses, which may be sustained or suffered by any of them arising out of or based upon any breach
by either Seller of any of its representations, warranties or covenants under this Agreement or any
of the other Transaction Documents, including, without limitation, any certificate, schedule,
exhibit or other instrument delivered pursuant hereto, to which either Seller is a party

(b) Limitations on Indemnification by the Sellers. Notwithstanding the foregoing, no
indemnification shall be payable pursuant to Section 9.1(a) (i) unless the total of all claims for
such indemnification exceeds the Indemnification Threshold, in which case the full amount of any
such claims shall be recoverable in accordance with the terms hereof or (ii) after indemnification
payments equal to the amount of the Indemnification Cap in the aggregate have been made. Any
amounts paid to a Buyer Indemnified Party pursuant to this Section 9.1 shall be returned to the
Sellers in the event that it is finally determined by a court of competent jurisdiction or an
arbitration tribunal that such Buyer Indemnified Party was not entitled to be indemnified
hereunder. In no event shall the Sellers be required to provide indemnification hereunder in an
aggregate amount greater than the Indemnification Cap. Any indemnification payments by a Seller
hereunder shall be made by wire transfer of immediately available funds to an account designated by
the Buyer.

9.2 Indemnification by the Buyer.

(a) Indemnification Obligations. Subject to the provisions of Section 9.2(b) below,
from and after the Closing, and in addition to any other rights and remedies the Seller may have
under this Agreement or pursuant to applicable law, the Buyer agrees to indemnify and hold each
Seller and its subsidiaries and Affiliates and persons serving as officers, directors, members,
attorneys, stockholders, partners or employees thereof (collectively the “Seller Indemnified
Parties”) harmless from and against any actual out-of-pocket damages, liabilities, losses, taxes,
fines, penalties, costs, and expenses (including, without limitation, reasonable fees and expenses
of counsel) of any kind or nature whatsoever (whether or not arising out of third-party claims and
including all reasonable amounts, paid in investigation, defense or settlement of the foregoing),
other than consequential, speculative, punitive or similar damages or losses, which may be
sustained or suffered by any of them arising out of or based upon any breach by the Buyer of any of
its representations, warranties or covenants under this Agreement or any of the other Transaction
Documents, including, without limitation, any certificate, schedule, exhibit or other instrument
delivered pursuant hereto, to which the Buyer is a party.

(b) Limitations on Indemnification by the Buyer. Notwithstanding the foregoing, no
indemnification shall be payable pursuant to Section 9.2(a) above (i) unless the total of all
claims for such indemnification exceeds the Indemnification Threshold, in which case the full
amount of any such claims shall be recoverable in accordance with the terms hereof or (ii) after
indemnification payments equal to the amount of the Indemnification Cap in the aggregate have been
made; provided, for the avoidance of doubt, that the Indemnification Cap shall not apply to the
Buyer’s obligation to deliver the Purchase Price pursuant to Section 2.2 hereof. Any amounts paid
to a Seller Indemnified Party pursuant to this Section 9.2 shall be returned to the Buyer in the
event that it is finally determined by a court of competent jurisdiction or an arbitration tribunal
that such Seller Indemnified Party was not entitled to be indemnified hereunder. Any
indemnification payments by the Buyer hereunder shall be made by wire transfer of immediately
available funds to an account designated by the Sellers.

9.3 Notice; Defense of Claims. An Indemnified Party may make claims for
indemnification hereunder by giving written notice thereof to the Indemnifying Party within the
period in which indemnification claims can be made hereunder. If indemnification is sought for a
claim or liability asserted by a third party, the Indemnified Party shall also give written notice
thereof to the Indemnifying Party promptly after it receives notice of the claim or liability
being asserted, but the failure to do so shall not relieve the Indemnifying Party from any
liability except to the extent that it is materially prejudiced by the failure or delay in giving
such notice. Such notice shall summarize the bases for the claim for indemnification and any
claim or liability being asserted by a third party. Within thirty (30) days after receiving such
notice the Indemnifying Party shall give written notice to the Indemnified Party stating whether
it disputes the claim for indemnification and whether it will defend against any third party claim
or liability at its own cost and expense. If the Indemnifying Party fails to give notice that it
disputes an indemnification claim within such thirty (30) day period, it shall be deemed to have
accepted and agreed to provide the indemnification required hereunder. The Indemnifying Party
shall be entitled to direct the defense against a third party claim or liability with counsel
selected by it (subject to the consent of the Indemnified Party, which consent shall not be
unreasonably withheld) as long as the Indemnifying Party is conducting a good faith and reasonably
diligent defense. The Indemnified Party shall at all times have the right to fully participate in
the defense of a third party claim or liability at its own expense directly or through counsel;
provided, however, that if the named parties to the action or proceeding include both the
Indemnifying Party and the Indemnified Party and the Indemnified Party is advised in writing by
its legal counsel that representation of both parties by the same counsel would be inappropriate
under applicable standards of professional conduct, the Indemnified Party may engage separate
counsel at the expense of the Indemnifying Party. If no such notice of intent to dispute and
defend a third party claim or liability is given by the Indemnifying Party, or if such good faith
and reasonably diligent defense is not being or ceases to be conducted by the Indemnifying Party,
the Indemnified Party shall have the right, at the expense of the Indemnifying Party, to undertake
the defense of such claim or liability (with counsel selected by the Indemnified Party). The
Indemnified Party shall make available such information and assistance as the Indemnifying Party
may reasonably request and shall cooperate with the Indemnifying Party in such defense, at the
expense of the Indemnifying Party. The Indemnifying Party shall not, in the defense of any third
party claim or litigation, enter into a consent or entry of judgment or enter into a settlement
that does not provide for a full and unconditional release of all liabilities on the part of the
Indemnified Party without the consent of the Indemnified Party, which consent will not be
unreasonably withheld.

9.4 Remedies. Except for (i) the indemnification provided for in Section 5.7(f) in
connection with a sale of Registrable Securities pursuant to a Registration Statement, (ii)
equitable relief pursuant to Section 10.14 and (iii) claims alleged to have occurred as the result
of fraud or intentional misconduct, the foregoing indemnification provisions are the sole and
exclusive remedy that any Party may have with respect to losses and other matters covered by or
arising out of this Agreement.

9.5 Payment of Indemnity Amounts by Sellers. Each Seller may make any indemnity
payment required to be made by it under Section 9.1 in cash, in shares of Ener1 Common Stock at a
value equal to the greater of (i) $7.20 per share (subject to adjustment for stock splits, stock
dividends and similar events) and (ii) the market value of the Ener1 Common Stock on the date such
payment becomes due, or in any combination of cash and such stock. For purposes of this Section
9.5, “market value” means, as of any date, the average closing bid price for the Ener1 Common
Stock on the American Stock Exchange (or such other principal exchange on which the Ener1 Common
Stock is then listed) during the period of five (5) trading days immediately prior to such date.

9.6 Limitations on Liability.

(a) Insured Claims. No liability for indemnification or otherwise shall attach to
either Seller in respect of any claim if and to the extent that such claim relates to any loss or
damage recoverable by the Buyer or any of the Buyer Indemnified Parties under any policy of
insurance or which would have been so recoverable but for any change in insurance coverage since
the Closing Date.

(b) Changes in Law. No liability for indemnification or otherwise shall attach to any
Party in respect of any claim to the extent that such claim would not have arisen (or the amount of
the claim would not have been increased) but for a change in legislation made after the date hereof
or a change in the interpretation of the law after the date hereof (whether or not such change
purports to be effective retrospectively in whole or in part).

(c) No Double Recovery. No Indemnified Party shall be entitled to recover damages or
obtain payment, reimbursement, restitution or indemnity more than once for or in relation to the
same loss, damage, deficiency or breach.

(d) Opportunity to Remedy. No liability shall attach to any Party in respect of any
claim if and to the extent that the breach giving rise to such claim is capable of remedy without
cost or loss to any Indemnified Party and is in fact remedied and such claim extinguished without
such cost or loss within thirty (30) days following (i) the date on which such Party received
notice from the Indemnified Party of such breach or (ii) if earlier, the date on which such Party
first became aware of such breach.

(e) Corresponding Benefit. In assessing any losses or other amounts for which an
Indemnified Party is entitled to indemnity hereunder, there shall be taken into account the value
of any benefit accruing to such Indemnified Party as a result of the resolution of the claim
pursuant to which such losses or other amounts became recoverable, including, without limitation,
the amount of any Tax relief obtained or obtainable by such Indemnified Party.

10. MISCELLANEOUS.

10.1 Fees and Expenses. Each of the Parties will bear its own expenses in connection
with the negotiation and the consummation of the transactions contemplated by this Agreement.

10.2 Governing Law; Jurisdiction; Venue. This Agreement shall be deemed to be a
contract made under, and shall be construed under and governed by the internal laws of the State
of New York, without regard for its conflict of law provisions. Subject to the provisions of
Section 10.3, (i) each of the parties hereto hereby agrees that the appropriate Courts of England
and Wales located in London, England shall have jurisdiction to hear and determine any claims or
disputes between the parties pertaining directly or indirectly to this Agreement, and all
documents, instruments and agreements executed pursuant hereto, or to any matter arising herefrom
(unless otherwise expressly provided for herein or therein); and (ii) to the extent permitted by
law, the parties hereby expressly submit and consent in advance to such jurisdiction in any action
or proceeding commenced in any of such courts, and agree that service of such summons and
complaint or other process or papers may be made by registered or certified mail addressed to the
Party at the address to which notices are to be sent pursuant to this Agreement. Each Party
waives any claim that London, England is an inconvenient forum or an improper forum based on lack
of venue. The prevailing Party in any such litigation is entitled to recover its reasonable
attorneys’ fees and costs.

10.3 Arbitration. Any dispute, controversy or difference arising between the Parties
out of or in relation to this Agreement or for the breach thereof shall be resolved exclusively by
arbitration in London, England. Such arbitration shall be conducted in the English language in
accordance with the Rules of Arbitration of the International Chamber of Commerce (“ICC”) by three
(3) arbitrators, of whom one shall be appointed by the Sellers, another shall be appointed by the
Buyer, and the third shall be appointed by the first two (2) arbitrators. If the third arbitrator
is not so appointed within one month after the appointment of the first two arbitrators, the third
arbitrator shall be selected in accordance with the rules of the ICC. The decision of the
arbitrators shall be made on the principles of majority rule. The award made by the arbitrators
shall be final and binding upon the Parties and may be enforced in any court of competent
jurisdiction. The prevailing Party in any such arbitration is entitled to recover its reasonable
attorneys’ fees and costs, including without limitation the cost of filing the arbitration claim.

10.4 Notices. Any notice, request, demand or other communication required or
permitted hereunder shall be in writing and shall be deemed to have been given if delivered by
hand, upon receipt, if sent by registered or certified mail or by private courier or delivery in
person, upon the date on which receipt is acknowledged, or if sent by facsimile transmission, upon
confirmation of transmission thereof. All notices to a Party will be sent to the addresses set
forth below or to such other address or person as such Party may designate by notice to the other
Party hereunder:

EMPLOYMENT AGREEMENT

This Employment Agreement (this “Agreement”), is executed and entered into by and between
MDRNA, INC., a Delaware corporation (the “Company”), with offices at 3830 Monte Villa Parkway,
Bothell, Washington 98021 and Barry Polisky, an individual resident in the State of Colorado (the
“Executive”), effective January 2, 2009 (the “Effective Date”).

W I T N E S S E T H :

WHEREAS, the Company and the Executive wish to enter into this Agreement, which shall set
forth the Executive’s terms of employment as Chief Scientific Officer of the Company,

NOW THEREFORE, in consideration of the mutual promises and agreements herein and for other
good and valuable consideration the receipt and sufficiency of which are hereby mutually
acknowledged, the Company and the Executive agree as follows:

1. Application and Effectiveness of Agreements. As of the Effective Date, this
Agreement shall govern (i) the employment relationship between the Company and the Executive and
(ii) other matters as set forth herein.

2. Employment; Responsibilities and Authority; Definitions.

(a) Subject to the terms and conditions of this Agreement, the Company shall employ the
Executive as its Chief Scientific Officer during the Employment Period (as defined in Section 3,
below) and the Executive shall perform such acts and duties and furnish such services to the
Company and its Subsidiaries (as defined below) as the Chief Executive Officer of the Company (the
“CEO”) shall from time to time direct.

(b) Subject to the terms and conditions of this Agreement, the Executive hereby accepts such
employment and agrees to devote his full time and continuous best efforts to the duties provided
for herein.

(c) For purposes of this Agreement: (1) the “Business of the Company” means the description
of the Company’s business as is described in Part I, Item 1 of the Company’s most recent Annual
Report on Form 10-K filed with the U.S. Securities and Exchange Commission (provided, however, that
for purposes of Sections 18(b) through (e) hereof, “Business of the Company” shall mean the
Company’s business as of the date of termination of Executive’s employment, as the same may have
changed since the Effective Date), and (2) the term “Subsidiary” means a corporation or other
entity that is at least majority owned, directly or indirectly, by the Company.

3. Term; Employment Period. The “Employment Period” under this Agreement shall
commence on the Effective Date and shall terminate at the close of business on January 3, 2012
unless it is (a) extended by written agreement between the parties or by continuing employment of
the Executive by the Company as provided in the following sentence or (b) earlier terminated
pursuant to Section 10 hereof. If the Executive shall remain in full-time employment by the
Company beyond what would otherwise be the end of the Employment Period without any written
agreement between the parties, this Agreement and the Employment Period shall be deemed to continue
on a quarter-to-quarter basis and either party shall have the right to terminate the Executive’s
employment hereunder at the end of any ensuing fiscal quarter on written notice of at least ninety
(90) days, unless earlier terminated pursuant to Section 10 hereof.

4. Salary. For services rendered to the Company during the Employment Period, the
Company shall compensate the Executive with a base salary, payable in semi-monthly installments,
which initially shall be three hundred and seventy-five thousand dollars ($375,000) per annum
commencing on the Effective Date, less all legally required or authorized payroll deductions and
tax withholdings. The Executive’s base salary shall be reviewed annually, and may be increased, at
the sole discretion of the Company’s Board of Directors (“Board”), in light of the Executive’s
performance and the Company’s financial performance and other economic conditions and relevant
factors. In addition, the Executive will receive a one-time signing bonus of twenty-five thousand
dollars ($25,000) within thirty (30) days of the Effective Date.

5. Incentive Cash Compensation.

(a) For the Company’s fiscal year that begins on January 1, 2009, and for each subsequent
fiscal year or portion thereof during the Employment Period, the Executive shall also be eligible
to receive incentive cash compensation based on the Executive’s performance in relation to the
performance areas and performance targets which the Board or Compensation Committee shall determine
and communicate to the Executive as described below (the “Annual Bonus Plan”). The targeted amount
of such Annual Bonus Plan shall be forty percent (40%) of the Executive’s base salary for the
applicable fiscal year (“Annual Bonus Target”); provided, however, that the Executive and the
Company acknowledge that the amount actually paid to the Executive pursuant to this Section 5 for
any fiscal year or portion thereof may be nil, or may be more or less than said targeted amount.

(b) The Board shall establish performance criteria for determination of the incentive cash
compensation under the Annual Bonus Plan that will be payable to the Executive with respect to each
fiscal year of the Company. To the extent possible, such criteria shall be established, as to each
fiscal year, prior to the end of the second month of such fiscal year. As an example, such
performance criteria may be comprised of several designated performance areas and one or more
performance targets in each area. The Company acknowledges that the business objectives used in
determining the Executive’s incentive cash compensation, and the performance areas and performance
targets referred to herein, shall be based on the input and recommendations of the Company’s Chief
Executive Officer and that, in exercising its review and supervisory role with respect to the
determination and adoption of those performance areas and performance targets, the Board or the
Compensation Committee, as the case may be, shall act reasonably and in consultation and
cooperation with the Chief Executive Officer and consistently with past practice.

(c) As soon as practical, and absent unforeseen circumstances no later than ninety (90) days
following the end of each fiscal year of the Company, the Board shall determine, reasonably and in
good faith, the extent to which the applicable performance criteria for such fiscal year shall have
been achieved and, accordingly, shall cause the appropriate amount of incentive cash compensation
to be paid to the Executive. If unforeseen developments occur that in the opinion of the Board
make the performance areas and/or targets previously determined unachievable, infeasible, or
inadvisable — and therefore inappropriate as a measure of the performance of the Executive — the
Board shall consider in good faith the extent to which the actual performance of the Executive
nevertheless warrants payment of the amounts that would have been payable if the performance
criteria had been achieved; and, to such extent, payment shall be made to the Executive.

6. Stock Options. The Company and the Executive hereby acknowledge that the Board of
Directors has previously approved the grant to the Executive of options to purchase shares of
common stock of the Company (which options shall constitute “incentive stock options” under the
Company’s 2008 Stock Incentive Plan (the “Plan”) to the extent permitted by law, with any excess
being non-qualified options; (the “Outstanding Options”)). The terms of the Plan and the grant
agreement granting such Outstanding Options, a copy of which is being delivered to Executive
substantially contemporaneously with the execution of this Agreement, shall govern the rights and
obligations of the Executive with respect thereto (which grant agreement incorporates the
provisions of this Section 6 and Sections 12 and 21 of this Agreement). Upon the Effective Date of
this Agreement, the Executive shall receive a grant of options to purchase 360,000 shares of common
stock of the Company. With respect to these options: (A) 120,000 options shall vest and be
exercisable on January 4, 2010 at the Fair Market Value (as defined in the Plan) calculated as of
the Effective Date (the “Effective Date Strike Price”); (B) 30,000 options shall vest and be
exercisable on each of April 2, 2010, July 2, 2010, October 2, 2010 and January 3, 2011 (for an
aggregate 120,000 options during such period) at the Effective Date Strike Price plus $1.00; and
(C) 30,000 options shall vest and be exercisable on each of April 2, 2011, July 2, 2011, October 2,
2011 and January 3, 2012 (for an aggregate 120,000 options during such period) with a strike price
equal to the Effective Date Strike Price plus $2.00. In addition, during the Employment Period
the Board of Directors may grant additional options to purchase shares of common stock of the
Company to the Executive.

7. Temporary Housing and Related Travel. The Company acknowledges that Executive’s
home residence is in Colorado. The Company shall reimburse Executive for his reasonable travel
expenses from his home residence to Bothell, Washington. Reasonable travel expenses will be
limited to coach airfare and ground transportation to/from his home and the airport and to/from the
airport to his temporary residence in Washington. Reimbursements shall be made pursuant to
Company’s reimbursement policy and consistent with Section 12 hereof.

8. Benefits. During the Employment Period, the Company shall provide or cause to be
provided to the Executive at least such employee benefits as are provided to other executive
officers of the Company. The Company reserves the right to change or eliminate employee benefits
on a prospective basis, at any time, effective upon notice to Executive.

9. Paid Time Off. The Executive shall be entitled to paid time off in accordance with
the Company’s policies in effect from time to time for executive officers of the Company.

10. Termination. 

(a) Executive’s employment by the Company shall be “at will.” Either the Company or the
Executive may terminate Executive’s employment by the Company at the end of any calendar month,
with or without Cause or Good Reason (as such terms are defined below), in its or
his sole discretion, upon thirty (30) days’ prior written notice of termination. In addition, the
Executive’s employment by the Company shall be terminated by his death or “Disability” (as defined

Employment Period.

(b) For purposes of this Agreement, in the case of a termination of the Executive’s employment

giving rise to such Good Reason, and the Company shall have 30 days from the date of such notice to
cure and remediate such condition and thereby eliminate the Good Reason.

(ii) “Cause” shall mean (i) the Executive’s willful and repeated failure to perform his duties
hereunder or to comply with any reasonable and proper direction given by the Company’s Chief

the Executive within thirty (30) days following receipt by the Executive of written notice from the
Company containing a reference to the violation and a demand for immediate cure thereof.

other employment or otherwise. The Executive’s acceptance of any other employment shall not
diminish or impair the amounts otherwise payable to the Executive hereunder.

15. Place of Performance. The Executive shall perform his duties at the main offices
of the Company subject to reasonable travel requirements which may be authorized and directed from
time to time by the Board.

16. Insurance and Indemnity. With respect to his service hereunder, the Company shall
maintain, at its expense, customary directors’ and officers’ liability and errors and omissions
insurance covering the Executive and, if such coverage is available at reasonable cost, for all
other executive officers and directors of the Company, in an amount both deemed appropriate by the
Company and available in the marketplace. To the extent such defense and indemnification are not
fully and irrevocably provided by Company-supplied insurance, the Company shall defend and
indemnify the Executive, to the fullest extent permitted by law, from and against any liability
asserted against or incurred by the Executive (a) by reason of the fact that the Executive is or
was an officer, director, employee, or consultant of the Company or is or was serving in any
capacity at the direction of the Company for any other corporation, partnership, joint venture,
trust, employment benefit plan or other entity or enterprise or (b) in connection with any
action(s), omission(s), or occurrence(s) during the course of such service or such status as an
officer, director, employee, or consultant of or to any of the foregoing. The Company’s
obligations under this Section 16 shall survive the termination of the Executive’s employment
hereunder and any termination of this Agreement.

17. Non-Competition.

(a) The Executive agrees that, except in accordance with his duties under this Agreement on
behalf of the Company, he will not during the Employment Period: participate in, be employed in
any capacity by, serve as director, consultant, agent or representative for, or have an interest,
directly or indirectly in, any enterprise which is engaged in the business of developing,
licensing, or selling technology, products or services which are directly competitive with the
Business of the Company or any of its Subsidiaries or with any technology, products or services
being actively developed, with the bona fide intent to market same, by the Company or any of its
Subsidiaries at the time in question; provided, however, that interests in publicly-traded entities
that constitute less than a five percent (5%) interest in such entities, and do not otherwise
constitute control either directly or indirectly of such entities, which interests were acquired or
are held for investment purposes, shall not be deemed to be a violation of this paragraph.

(b) In addition, the Executive agrees that, for a period of six (6) months after the end of
the Executive’s employment by the Company (unless such employment is terminated by the Company
without Cause, or by the Executive for Good Reason, in which event the following shall be
inapplicable), the Executive shall not (1) own, either directly or indirectly or through or in
conjunction with one or more members of his or his spouse’s family or through any trust or other
contractual arrangement, a greater than five percent (5%) interest in, or otherwise control either
directly or indirectly, or (2) participate in, be employed in any capacity by, or serve as
director, consultant, agent or representative for, any partnership, corporation, or other entity
which is engaged in the business of developing, licensing, or selling technology, products or
services which are directly competitive with the Business of the Company or any of its Subsidiaries
as of the termination of the Executive’s employment with the Company or which are directly
competitive with any technology, products, or services being actively developed by the Company or
any of its Subsidiaries, with the bona fide intent to market same, as of the termination of the
Executive’s employment at the Company.

(c) Executive further agrees, for twelve (12) months following the end of the Executive’s
employment by the Company (unless such employment is terminated by the Company without Cause, or by
the Executive for Good Reason, in which event the following shall be inapplicable), to refrain from
directly or indirectly soliciting or hiring the Company’s collaborative partners, consultants,
certified research organizations, principal vendors, licensees or employees except any such
solicitation in connection with activities that would not be directly competitive with and/or
adverse to the Business of the Company or any of its Subsidiaries or with and to any products or
services being offered by the Company or any of its Subsidiaries at the date such employment
terminated or then being actively developed, with the bona fide intent to market same, by the
Company or any of its Subsidiaries.

(d) Executive further agrees, while employed by the Company and for six (6) months following
the end of the Executive’s employment by the Company (unless such employment is terminated by the
Company without Cause, or by the Executive for Good Reason, in which event the following shall be
inapplicable), that he will not, directly or indirectly, as a sole proprietor, member of a
partnership or as a stockholder, investor, officer or director of a corporation, or as an employee,
agent, associate or consultant of any person, firm or corporation, other than for the exclusive
benefit of the Company or any of its Subsidiaries, solicit or accept business from, or perform or
supervise the performance of any services related to such business for, (i) any client of the
Company or any of its Subsidiaries who was a client during the Executive’s employment with the
Company, (ii) any clients or prospective clients of the Company or any of its Subsidiaries who were
solicited or serviced, directly or indirectly, by the Executive, in whole or in part, or (iii) any
former client of the Company or any of its Subsidiaries who was a client within one (1) year prior
to the Executive’s termination of employment and who was solicited or serviced, directly or
indirectly, by the Executive, or by those supervised, directly or indirectly, by the Executive, in
whole or in part, in connection with activities that would be directly competitive with and/or
adverse to the Business of the Company or any of its Subsidiaries or with and to any products or
services being offered by the Company or any of its Subsidiaries at the date such employment
terminated or then being actively developed, with the bona fide intent to market same, by the
Company or any of its Subsidiaries.

(e) The Executive hereby agrees that damages and any other remedy available at law would be
inadequate to redress or remedy any loss or damage suffered by the Company upon any breach of the
terms of this Section 17 by the Executive, and the Executive therefore agrees that the Company, in
addition to recovering on any claim for damages or obtaining any other remedy available at law,
also may enforce the terms of this Section 17 by injunction or specific performance, and may obtain
any other appropriate remedy available in equity.

18. Assignment of Patents. Executive shall disclose fully to the Company any and all
discoveries he shall make and any and all ideas, concepts or inventions he shall conceive or make
that are related or applicable to the Business of the Company or of any of its Subsidiaries or to
any other products, services, or technology in medicine or the health sciences in which the Company
shall during the Employment Period undertake, or actively and in good faith consider, research or
commercial involvement; provided, however, that either (a) such discovery(ies), idea(s), concept(s)
and/or invention(s) are made by the Executive during the Employment Period or (b) such
discovery(ies), idea(s), concept(s) and/or invention(s) are made by the Executive during the period
of six (6) months after his employment terminates and are in whole or in part the result of his
work with the Company. Such disclosure is to be made promptly after each such discovery or
conception, and each such discovery, idea, concept or invention will become and remain the property
of the Company, whether or not patent applications are filed thereon. Upon the request and at the
expense of the Company, the Executive shall (i) make application through the patent solicitors of
the Company for letters patent of the United States and any and all other countries at the
discretion of the Company on such discoveries, ideas and inventions, and (ii) assign all such
applications to the Company, or at its order, without additional payment by the Company except as
otherwise agreed by the Company and the Executive. The Executive shall give the Company, its
attorneys and solicitors, reasonable assistance in preparing and prosecuting such applications and,
on request of the Company, execute such papers and do such things as shall be reasonably necessary
to protect the rights of the Company and vest in it or its assigns the discoveries, ideas or
inventions, applications and letters patent herein contemplated. Said cooperation shall also
include such actions as are reasonably necessary to aid the Company in the defense of its rights in
the event of litigation. This Section 18 shall not apply to any invention for which no equipment,
supplies, facilities, or trade secret information of the Company or its Subsidiaries was used, and
which was developed entirely on the Executive’s own time, unless (i) the invention relates directly
to the Business of the Company or of any of its Subsidiaries or to the actual or demonstrably
anticipated research or development of the Company or of any of its Subsidiaries, or (ii) the
invention results from any work performed by the Executive for the Company.

19. Confidential Information/Trade Secrets.

(a) In the course of the term of this Agreement, it is anticipated that the Executive shall
have access to secret or confidential technical, scientific and commercial information, records,
data, formulations, specifications, systems, methods, plans, policies, inventions, material and
other knowledge that is (are) specifically related or applicable to the Business of the Company or
of any of its Subsidiaries or to any other products, services, or technology in medicine or the
health sciences in which the Company shall during the Employment Period undertake, or actively and
in good faith consider, research or commercial involvement and that is/are owned by the Company or
its Subsidiaries (“Confidential Material”). The Executive recognizes and acknowledges that
included within the Confidential Material are the following as they may specifically relate or be
applicable to the Company’s Business or technology, or to current or specifically contemplated
future Company products or services: the Company’s confidential commercial information,
technology, formulations, trade secrets, know-how, methods of manufacture, chemical formulations,
device designs, pending patent applications, clinical data, pre-clinical data and any related
materials, all as they may exist from time to time, and that such material is or may be valuable
special, and unique aspects of the Company’s business. All such Confidential Material shall be and
remain the property of the Company. Except as required by his duties to the Company, the Executive
shall not, directly or indirectly, either during the term of his employment or at any time
thereafter, disclose or disseminate to anyone or make use of, for any purpose whatsoever, any
Confidential Material. Upon termination of his employment, the Executive shall promptly deliver to
the Company all Confidential Material (including all copies thereof, whether prepared by the
Executive or others) which are in the possession or under the control of the Executive. The
Executive shall not be deemed to have breached this Section 19 if the Executive is compelled by
legal process or order of any judicial, legislative, or administrative authority or body to
disclose any Confidential Material; provided that Executive shall give prompt notice of
such process or order to the Company, and the Executive shall in good faith use reasonable efforts
to provide the Company the opportunity to intervene in the event Executive may be compelled to
disclose Confidential Information of the Company pursuant to such process or order.

(b) The Executive hereby agrees that damages and any other remedy available at law would be
inadequate to redress or remedy any loss or damage suffered by the Company upon any breach of the
terms of this Section 19 by the Executive, and the Executive therefore agrees that the Company, in
addition to recovering on any claim for damages or obtaining any other remedy available at law,
also may enforce the terms of this Section 19 by injunction or specific performance, and may obtain
any other appropriate remedy available in equity.

20. Payment and Other Provisions After Change of Control. 

(a) If, within one (1) year following the occurrence of a Change of Control (as defined below)
the Executive’s employment with the Company is terminated either by the Company or by the Executive
(other than because of the Executive’s death or Disability), and such termination is without Cause
if by the Company, or for Good Reason if by Executive, or if upon the expiration of any Employment
Period the Company shall fail to offer to renew or extend the Employment Period (other than if the
Executive shall then have reached the Company’s mandatory retirement age), then the Executive shall
be entitled to receive from the Company Executive’s Accrued Salary and Benefits and, in lieu of the
Severance Package otherwise payable pursuant to Section 11 hereof, Executive will receive the
following (provided Executive complies with the Severance Requirements described in Section 11(a)
above):

(i) Additional Amount Based on Base Salary. A lump-sum amount equal to the
greater of: (a) twelve (12) months of Executive’s specified base salary hereunder, and (b)
the balance of Executive’s specified base salary hereunder to the end of the term of this
Agreement;

(ii) Incentive Cash Compensation. A pro-rata amount of the Executive’s Annual Bonus
Target for the fiscal year in which the date of termination occurs, plus an additional lump-sum
payment equal to fifty percent (50%) of the Executive’s base salary for such year; and

(iii) Other Benefits. Notwithstanding the vesting and/or exercisability provisions
otherwise applicable to Outstanding Options, all such stock options shall be fully vested and
exercisable upon a Change of Control and shall remain exercisable as specified in the option grant
agreements, and subject to the right of the Company to direct the sale of shares in connection with
a Change of Control.

Except to the extent that more time is required to determine the incentive cash compensation
payable pursuant to Section 20(a)(ii) hereof, the Company shall pay the cash amounts provided for
in this Section 20(a) within thirty (30) days after the six (6) month anniversary of the date of
such termination (but no later than the end of the calendar year in which such six (6) month
anniversary occurs).

(b) For purposes of this Agreement, the term “Change of Control” shall mean:

(i) The acquisition by any individual, entity or group (within the meaning of Rule 13d-3
promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or any
successor provision) (any of the foregoing hereafter a “Person”) of forty percent (40%) or more of
either (a) the then outstanding shares of Capital Stock of the Company (the “Outstanding Capital
Stock”) or (b) the combined voting power of the then outstanding voting securities of the Company
entitled to vote generally in the election of directors (the “Voting Securities”), provided,
however, that such an acquisition by one of the following shall not constitute a change of control:
(1) the Company or any of its Subsidiaries, or any employee benefit plan (or related trust)
sponsored or maintained by the Company or any of its Subsidiaries or (2) any Person that is
eligible, pursuant to Rule 13d-1(b) under the Exchange Act, to file a statement on Schedule 13G
with respect to its beneficial ownership of Voting Securities, whether or not such Person shall
have filed a statement on Schedule 13G, unless such Person shall have filed a statement on
Schedule 13D with respect to beneficial ownership of forty percent (40%) or more of the Voting
Securities or (3) any corporation with respect to which, following such acquisition, more than
sixty percent (60%) of both the then outstanding shares of common stock of such corporation and the
combined voting power of the then outstanding voting securities of such corporation entitled to
vote generally in the election of directors is then beneficially owned, directly or indirectly, by
all or substantially all of the individuals and entities who were the beneficial owners,
respectively, of the Outstanding Capital Stock or Voting Securities immediately prior to such
acquisition in substantially the same proportions as their ownership, immediately prior to such
acquisition, of the Outstanding Capital Stock or Voting Securities, as the case may be; or

(ii) Individuals who, as of the Effective Date, constitute the Board (the “Incumbent Board”)
cease for any reason to constitute at least a majority of the Board, provided that any individual
becoming a director subsequent to the Effective Date whose election or nomination for election by
the Company’s shareholders was approved by a vote of at least a majority of the directors then
comprising the Incumbent Board shall be considered as though such individual were a member of the
Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of
office is in connection with an actual or threatened election contest relating to the election of
the Directors of the Company (as such terms are used in Rule 14a-11 of Regulation 14A, or any
successor section, promulgated under the Exchange Act); or

(iii) Approval by the shareholders of the Company of a reorganization, merger or consolidation
(a “Business Combination”), in each case, with respect to which all or substantially all holders of
the Outstanding Capital Stock and Voting Securities immediately prior to such Business Combination
do not, following such Business Combination, beneficially own, directly of indirectly, in
substantially the same proportions, more than sixty percent (60%) of, respectively, the then
outstanding shares of common stock and the combined voting power of the then outstanding voting
securities entitled to vote generally in the election of directors, as the case may be, of the
corporation resulting from the Business Combination; or

(iv) A complete liquidation or dissolution of the Company; or

(v) A sale or other disposition of all or substantially all of the assets of the Company other
than to a corporation with respect to which, following such sale or disposition, more than sixty
percent (60%) of the then outstanding shares of common stock and the combined voting power of the
then outstanding voting securities entitled to vote generally in the election of directors are then
owned beneficially, directly or indirectly, by all or substantially all of the individuals and
entities who were the beneficial owners, respectively, of the Outstanding Capital Stock or Voting
Securities Immediately prior to such sale or disposition in substantially the same proportions as
their ownership of the Outstanding Capital Stock and Voting Securities, as the case may be,
immediately prior to such sale or disposition.

21. Notices. Any notice required or permitted to be given under this Agreement shall
be sufficient if in writing and personally delivered (including by regular messenger service,
signature required) or sent by registered or certified mail, return receipt requested, to both his
office and his residence, in the case of notices directed to the Executive, or to its principal
office, Attn.: Chief Financial Officer, in the case of notices directed to the Company, or to such
other address and/or addressee as the party to whom such notice is directed shall have designated
for this purpose by notice to the other in accordance with this Section. Such notices shall be
effective upon personal delivery or three (3) days after mailing.

22. Entire Agreement; Waiver. This Agreement contains the entire understanding of the
parties with respect to the subject matter hereof (it being acknowledged, however, that the Company
and the Executive may enter into certain grant agreements relating to Outstanding Options which
shall be effective in accordance with the terms thereof ). This Agreement may not be changed
orally but only by an instrument in writing, signed by the party against whom enforcement of any
waiver, change, modification or discharge is sought; provided that should the Executive be
appointed by the Board to an additional executive office of the Company during the Employment
Period, the terms of this Agreement shall apply, the references to “Chief Scientific Officer” shall
be deemed to read “Chief Scientific Officer and [insert office]”, and the compensation provisions
hereof shall continue unamended. Waiver of or failure to exercise any rights provided by this
Agreement in any respect shall not be deemed a waiver of any further or future rights.

23. Binding Effect; Assignment. The rights and obligations of this Agreement shall
bind and inure to the benefit of any successor of the Company by reorganization, merger or
consolidation, or any transferee of all or substantially all of the Company’s business or
properties. The Executive’s rights hereunder are personal to and shall not be transferable nor
assignable by the Executive.

24. Headings. The headings contained in this Agreement are for reference purposes
only and shall not affect the meaning or interpretation of this Agreement.

25. Governing Law; Arbitration. This agreement shall be construed in accordance with
and governed for all purposes by the laws of the State of Washington applicable to contracts made
and to be performed wholly within such state. Except as otherwise provided in Sections 18(e) and
20(b) of this Agreement, any dispute or controversy arising out of or relating to this Agreement
shall be settled by arbitration in accordance with the rules of the American Arbitration
Association, and judgment upon the award may be entered in any court having jurisdiction thereover.
The arbitration shall be held in King County, Washington or in such other place as the parties
hereto may agree.

26. Further Assurances. Each of the parties agrees to execute, acknowledge, deliver
and perform, and cause to be executed, acknowledged, delivered and performed, at any time and from
time to time, all such further acts, deeds, assignments, transfers, conveyances, powers of attorney
and/or assurances as may be necessary or proper to carry out the provisions or intent of this
Agreement.

27. Severability. The parties agree that if any one or more of the terms, provisions,
covenants or restrictions of this Agreement shall be determined by a court of competent
jurisdiction to be invalid, void, or unenforceable, the remainder of the terms, provisions,
covenants and restrictions of this Agreement shall remain in full force and effect and shall in no
way be affected, impaired or invalidated.

28. Application of Section 409A.

(a) Notwithstanding anything set forth in this Agreement to the contrary, no amount payable
pursuant to this Agreement which constitutes a “deferral of compensation” within the meaning of
Section 409A of the Code (“Section 409A”) shall be paid unless and until the Executive has
incurred a “separation from service” within the meaning of Section 409A. Further, to the extent
that the Executive is a “specified employee” within the meaning of Section 409A as of the date of
the Executive’s separation from service, no amount that constitutes a deferral of compensation
which is payable on account of the Executive’s separation from service shall be paid to the
Executive before the date (the “Delayed Payment Date”) which is the first (1st)
day of the seventh (7th) month after the date of the Executive’s separation from service
or, if earlier, the date of the Executive’s death following such separation from service. All such
amounts that would, but for this Section 12, become payable prior to the Delayed Payment Date will
be accumulated and paid on the Delayed Payment Date.

(b) The Company intends that income provided to the Executive pursuant to this Agreement will
not be subject to taxation under Section 409A. The provisions of this Agreement shall be
interpreted and construed in favor of satisfying any applicable requirements of Section 409A. The
Company and the Executive agree to negotiate in good faith to reform any provisions of this
Agreement to maintain to the maximum extent practicable the original intent of the applicable
provisions without violating the provisions of Section 409A, if the Company deems such reformation
necessary or advisable pursuant to guidance under Section 409A to avoid the incurrence of any such
interest and penalties. Such reformation shall not result in a reduction of the aggregate amount
of payments or benefits under this Agreement. However, the Company does not guarantee any
particular tax effect for income provided to the Executive pursuant to this Agreement. In any
event, except for the Company’s responsibility to withhold applicable income and employment taxes
from compensation paid or provided to the Executive, the Company shall not be responsible for the
payment of any applicable taxes on compensation paid or provided to the Executive pursuant to this
Agreement.

29. Counterparts. This Agreement may be executed in several counterparts, and all
counterparts so executed shall constitute one agreement, binding on the parties hereto,
notwithstanding that both parties are not signatory to the original or the same counterpart.
