Re: Transition Employment Agreement

Dear John,

This letter (our “Agreement”) will confirm our understanding with respect to your termination
as an employee of Deerfield Capital Management LLC (the “Company”) as a result of a reduction in
force. You acknowledge that this Agreement is intended only to resolve matters relating to your
employment with the Company and is not an admission of fault or liability on the part of you or the
Company. Subject to your continuing to comply with the terms of this Agreement, you and the
Company agree as follows:

1. As part of the Company’s reduction in force, you are scheduled to be terminated effective
December 31, 2008. The Company is offering you a choice in terms of severance arrangements as
follows (please initial the option you choose):

     X     Option 1: The Company is offering you the opportunity, in consideration
of your entering into this Agreement, to remain a Company employee from the date hereof
until April 18, 2009 or your earlier resignation (the “Transition Period”), at your current
salary and benefits and subject to the terms of this Agreement; or

If you do not wish to remain a Company employee after December 31, 2008, in consideration of
your entering into this Agreement, you may choose either of the following:

     Option 2: Although you will no longer be an employee, you may choose to receive
periodic payments through April 1, 2009 equivalent in amount and payment date to the
salary you would have received through that date if you had remained a Company employee
through that date; or

     Option 3: Receive a lump sum payment of $319,124.00. If you choose this option,
all salary payments will cease as of December 31, 2008. The lump sum payment will be made
to you promptly after the Effective Date, as defined in Paragraph 17 below, in accordance
with the Company’s normal payroll policies.

You have until December 31, 2008 to notify the Company of your intention to select one of the
above options. If you choose either Option 2 or Option 3, you would have no further employment
duties, access to the Company’s offices, or rights after your termination date.

2. Regardless of which of the above options you choose, you will also receive a separate lump
sum payment, representing your discretionary bonus for the 2008 calendar year, of $250,000.00, in
accordance with the Company’s standard bonus payment policy, which in any event will be no later
than March 31, 2009. You acknowledge that you are not otherwise entitled to the benefits that are
described in this paragraph and in Paragraph 1.

3. You agree that, in addition to complying with the terms of this Agreement, effective upon
the end of your Transition Period (if you choose Option 1 above), you will execute a release in the
form attached hereto as Exhibit A, which will release the Company from any claims that may have
arisen during the Transition Period (the “Second Release”). In consideration of this Second
Release, the Company will pay you an additional one week of salary at the rate of your current
annual salary, upon the expiration of the 7-day revocation period contained in the Second Release
in accordance with the Company’s normal payroll policies. You acknowledge that you are not
otherwise entitled to the benefits that are described in this paragraph. Notwithstanding anything
contained in this agreement, the Company retains the right to terminate you for cause during the
Transition Period and concurrently rescind its obligation to pay you the amounts set forth in
Paragraph 1 and Paragraph 2.

4. During the Transition Period (if you choose Option 1 above), you may make reasonable use
of the Company’s facilities for the purpose of seeking new employment and may, upon prior notice to
your supervisor, be absent from the Company’s premises for reasonable periods of time for the
purpose of seeking new employment.

5. Upon your execution of this Agreement or the Second Release, as applicable, the Company
agrees that it will not contest any claim for unemployment insurance benefits you may file with the
Illinois Department of Employment Security.

6. You, on behalf of your heirs, executors, administrators, assigns, successors and legal
representatives, release and forever discharge the Company, its affiliates, parent or subsidiary
entities or corporations, and its and their officers, directors, shareholders, employees, agents,
representatives, insurers, successors and assigns (“Company Affiliates”), from any and all claims,
liabilities, demands, sums of money, agreements, promises, damages, sums of money, costs or
expenses, attorneys fees, causes of action and liabilities of any kind or character whatsoever,
including all known and unknown claims, arising on or before the Effective Date (as hereafter
defined) which you now have or may hereafter have against the Company or any Company Affiliate
(other than the obligations described in this Agreement). You agree that the severance payments
described in Paragraphs 1 and 2 hereof, and the Company’s promises in Paragraphs 4 and 5 hereof,
represent full and complete consideration for the release you are providing and for any other
promises you are making in this Agreement. Nothing in this Agreement shall constitute a release of
any of your rights to any vested benefits or rights to indemnification under the Company’s
insurance policies, bylaws or other applicable agreements.

7. Your release includes any claims or causes of action you might have under any local,
federal or state law, including the Illinois Human Rights Act, the Federal Age Discrimination in
Employment Act of 1967, as amended, the Civil Rights Act of 1964, as amended; the Americans with
Disabilities Act; the Equal Pay Act; the Employee Retirement Income Security Act of 1974, as
amended; the Family and Medical Leave Act of 1993; the Civil Rights Act of April 9, 1866; the
Federal Occupation Safety and Health Act; and the Chicago Human Rights Ordinance.

8. (a) You represent that you have not filed any complaints or charges or lawsuits against
the Company or Company Affiliates in any court or before any government agency except for a claim
for unemployment insurance benefits. You further represent that you have advised the Company of
any potential claims you may have regarding your employment with the Company as of the date you
sign this Agreement.

(b) The Company represents that it has not filed any complaints or charges or lawsuits
against you in any court or before any governmental agency. The Company further represents that it
has advised you that it is not aware of any potential claims it may have regarding your employment
with the Company as of the date you sign this Agreement.

9. You agree that you will not make any disparaging or untrue statements concerning the
Company or Company Affiliates.

10. The Company agrees that in response to appropriate inquiries, in accordance with its
standard policy, it will provide a neutral reference concerning your employment with the Company.

11. Other than to carry out its terms, the Agreement shall not be used or offered by any
person for any purpose, including as an admission of liability or wrongdoing or the validity or
invalidity of any claims which were or could have been asserted by either you or the Company.

12. This Agreement embodies the sole and entire Agreement between you and the Company
concerning the resolution of all matters concerning your employment with the Company, and
supersedes any and all prior agreements, arrangements and understandings you or the Company may
have regarding your employment or compensation, except for your obligations under your
Confidentiality Agreement with the Company and your employment agreement with the Company dated
June 26, 2004; each of which shall remain in full force and effect after your employment with the
Company terminates.

13. The provisions of this Agreement may be modified only by the written agreement of you and
the Company.

14. In executing this Agreement, you represent that you are not relying on any inducements,
promises or representations of the Company or Company Affiliates other than expressly set forth in
this Agreement.

15. If any provision of this Agreement shall be deemed invalid under applicable law, such
provision shall be deemed omitted, but the remaining provisions of this Agreement shall remain in
full force and effect.

16. You agree and acknowledge that this Agreement will be disclosed publicly in a Form 8-K to
be filed by the Company with the Securities and Exchange Commission.

17. All disputes arising in connection with this Agreement or any rights arising pursuant to
this Agreement shall be resolved by binding arbitration in accordance with the applicable rules of
the American Arbitration Association. The arbitration shall be held in Cook County, Illinois
before a single arbitrator selected in accordance with Section 11 of the American Arbitration
Association Commercial Arbitration Rules who shall have (i) substantial business experience in the
investment advisory industry, and shall otherwise be conducted in accordance with the American
Arbitration Association Commercial Arbitration Rules and (ii) the right to award to any party any
right or remedy that is available under applicable law. The award of the arbitrator shall be final
and binding and may be entered and enforced in any court of competent jurisdiction.

18. This Agreement is binding upon the Company and its successors and assigns.

19. If this Agreement correctly reflects the understanding reached between you and the
Company, please sign and return the two enclosed copies of this Agreement. You should consult with
an attorney before you sign this Agreement, and you have forty-five (45) calendar days in which to
consider whether to sign. You may waive this 45 day consideration period. After you sign this
Agreement, you have seven (7) calendar days during which you may revoke this Agreement, and this
Agreement will not become effective until this seven day period has expired (the “Effective Date”).

20. We have attached to this Agreement a schedule containing the job titles and ages of all
employees affected by this reduction in force, and the ages of all individuals with the same job
classification not affected by this reduction in force.

The Company anticipates your cooperation during your Transition Period, and wishes you good
luck in your future endeavors thereafter.

WARRANT

TO PURCHASE COMMON STOCK 

OF

ENER1, INC.

Issue Date:      

THIS CERTIFIES that ENER1 GROUP, INC., a Florida corporation, or any subsequent holder
hereof (the “Holder”), has the right to purchase from ENER1, INC., a Florida corporation (the
“Company”), up to      (     ) fully paid and nonassessable shares of the Company’s
common stock, par value $0.01 per share (the “Common Stock”), subject to adjustment as provided
herein, at a price per share equal to the Exercise Price (as defined below), at any time and from
time to time beginning on the date on which this Warrant was originally issued (the “Issue Date”)
and ending at 5:00 p.m., eastern time, on      (the “Expiration Date”); provided,
however, that if the Expiration Date occurs on a date that is not a Business Day, the Expiration
Date shall be deemed to occur on the on the Business Day immediately following such date. This
Warrant is issued pursuant to the terms of a Line of Credit Agreement, dated as of December 29,
2008 (the “LOC Agreement”). Capitalized terms used herein and not otherwise defined shall have the
respective meanings set forth in the LOC Agreement.

1. Exercise.

(a) Right to Exercise; Exercise Price. The Holder shall have the right to exercise
this Warrant at any time and from time to time during the period beginning on the Issue Date and
ending on the Expiration Date as to all or any part of the shares of Common Stock covered hereby
(the “Warrant Shares”). The “Exercise Price” for each Warrant Share purchased by the Holder upon
the exercise of this Warrant shall be equal to $8.25, subject to adjustment for the events
specified in Section 6 below.

(b) Exercise Notice. In order to exercise this Warrant, the Holder shall send to the
Company by facsimile transmission, at any time prior to 6:00 p.m., eastern time, on the Business
Day on which the Holder wishes to effect such exercise (the “Exercise Date”), (i) a notice of
exercise in substantially the form attached hereto as Exhibit A (the “Exercise Notice”), (ii) a
copy of the original Warrant, and (iii) the Exercise Price by wire transfer of immediately
available funds. The Exercise Notice shall state the name or names in which the shares of Common
Stock that are issuable on such exercise shall be issued. In the case of a dispute between the
Company and the Holder as to the calculation of the Exercise Price or the number of Warrant Shares
issuable hereunder (including, without limitation, the calculation of any adjustment pursuant to
Section 6 below), the Company shall issue to the Holder the number of Warrant Shares that are not
disputed within the time periods specified in Section 2 below and shall submit the disputed
calculations to a certified public accounting firm of national reputation (other than the Company’s
regularly retained accountants) within two (2) Business Days following the date on which the
Holder’s Exercise Notice is delivered to the Company. The Company shall cause such accountant to
calculate the Exercise Price and/or the number of Warrant Shares issuable hereunder and to notify
the Company and the Holder of the results in writing no later than three (3) Business Days
following the day on which such accountant received the disputed calculations (the “Dispute
Procedure”). Such accountant’s calculation shall be deemed conclusive absent manifest error. The
fees of any such accountant shall be borne by the party whose calculations were most at variance
with those of such accountant.

(c) Holder of Record. The Holder shall, for all purposes, be deemed to have become
the holder of record of the Warrant Shares specified in an Exercise Notice on the Exercise Date
specified therein, irrespective of the date of delivery of such Warrant Shares. Except as
specifically provided herein, nothing in this Warrant shall be construed as conferring upon the
Holder hereof any rights as a shareholder of the Company prior to the Exercise Date.

(d) Cancellation of Warrant. This Warrant shall be canceled upon its exercise in full
and, if this Warrant is exercised in part, the Company shall, at the time that it delivers Warrant
Shares to the Holder pursuant to such exercise as provided herein, issue a new warrant, and deliver
to the Holder a certificate representing such new warrant, with terms identical in all respects to
this Warrant (except that such new warrant shall be exercisable into the number of shares of Common
Stock with respect to which this Warrant shall remain unexercised); provided, however, that the
Holder shall be entitled to exercise all or any portion of such new warrant at any time following
the time at which this Warrant is exercised, regardless of whether the Company has actually issued
such new warrant or delivered to the Holder a certificate therefor.

2. Delivery of Warrant Shares Upon Exercise. Upon receipt of a fax copy of an
Exercise Notice pursuant to Section 1 above, the Company shall, (A) no later than the close of
business on the later to occur of (i) the third (3rd) Business Day following the Exercise Date
specified in such Exercise Notice and (ii) such later date on which the Company shall have received
payment of the Exercise Price, and (B) with respect to Warrant Shares that are the subject of a
Dispute Procedure, the close of business on the third (3rd) Business Day following the
determination made pursuant to Section 1(b) (each of the dates specified in (A) or (B) being
referred to as a “Delivery Date”), issue and deliver or caused to be delivered to the Holder the
number of Warrant Shares as shall be determined as provided herein. The Company shall effect
delivery of Warrant Shares to the Holder, as long as the Company’s designated transfer agent (the
“Transfer Agent”) participates in the Depository Trust Company (“DTC”) Fast Automated Securities
Transfer program (“FAST”) and no restrictive legend is required pursuant to the terms of this
Warrant or the LOC Agreement, by crediting the account of the Holder or its nominee at DTC (as
specified in the applicable Exercise Notice) with the number of Warrant Shares required to be
delivered, no later than the close of business on such Delivery Date. In the event that the
Transfer Agent is not a participant in FAST or if the Holder so specifies in a Exercise Notice or
otherwise in writing on or before the Exercise Date, the Company shall effect delivery of Warrant
Shares by delivering to the Holder or its nominee physical certificates representing such Warrant
Shares, no later than the close of business on such Delivery Date. Warrant Shares delivered to the
Holder shall not contain any restrictive legend unless such legend is required pursuant to the
terms of the LOC Agreement.

3. Failure to Deliver Warrant Shares.

(a) In the event that the Company fails for any reason to deliver to the Holder the number of
Warrant Shares specified in the applicable Exercise Notice on or before the Delivery Date therefor
(an “Exercise Default”), the Company shall pay to the Holder payments (“Exercise Default Payments”)
in the amount of (i) (N/365) multiplied by (ii) the aggregate Exercise Price of the Warrant
Shares which are the subject of such Exercise Default multiplied by (iii) the lower of
fifteen percent (15%) per annum and the maximum rate permitted by applicable law (the “Default
Interest Rate”), where “N” equals the number of days elapsed between the original Delivery Date of
such Warrant Shares and the date on which all of such Warrant Shares are issued and delivered to
the Holder. Cash amounts payable hereunder shall be paid on or before the fifth (5th) Business Day
of each calendar month following the calendar month in which such amount has accrued.

(b) In the event of an Exercise Default, the Holder may, upon written notice to the Company
(an “Exercise Default Notice”), regain on the date of such notice the rights of the Holder under
the exercised portion of this Warrant that is the subject of such Exercise Default. In the event
of such Exercise Default and delivery of an Exercise Default Notice, the Holder shall retain all of
the Holder’s rights and remedies with respect to the Company’s failure to deliver such Warrant
Shares (including without limitation the right to receive the cash payments specified in Section
3(a) above).

(c) The Holder’s rights and remedies hereunder are cumulative, and no right or remedy is
exclusive of any other. In addition to the amounts specified herein, the Holder shall have the
right to pursue all other remedies available to it at law or in equity (including, without
limitation, a decree of specific performance and/or injunctive relief). Nothing herein shall limit
the Holder’s right to pursue actual damages for the Company’s failure to issue and deliver Warrant
Shares on the applicable Delivery Date (including, without limitation, damages relating to any
purchase of Common Stock by the Holder to make delivery on a sale effected in anticipation of
receiving Warrant Shares upon exercise, such damages to be in an amount equal to (A) the aggregate
amount paid by the Holder for the Common Stock so purchased minus (B) the aggregate amount
of net proceeds, if any, received by the Holder from the sale of the Warrant Shares issued by the
Company pursuant to such exercise).

4. Exercise Limitations. In no event shall a Holder be permitted to exercise this
Warrant, or part hereof, if, upon such exercise, the number of shares of Common Stock beneficially
owned by the Holder (other than shares which would otherwise be deemed beneficially owned except
for being subject to a limitation on conversion or exercise analogous to the limitation contained
in this Section 4), would exceed 9.99% of the number of shares of Common Stock then issued and
outstanding. As used herein, beneficial ownership shall be determined in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended, and the rules thereunder. To the extent
that the limitation contained in this Section 4 applies, the submission of an Exercise Notice by
the Holder shall be deemed to be the Holder’s representation that this Warrant is exercisable
pursuant to the terms hereof and the Company shall be entitled to rely on such representation
without making any further inquiry as to whether this Section 4 applies. Nothing contained herein
shall be deemed to restrict the right of a Holder to exercise this Warrant, or part thereof, at
such time as such exercise will not violate the provisions of this Section 4. This Section 4 may
not be amended unless such amendment is approved by the holders of a majority of the Common Stock
then outstanding; provided, however, that the limitations contained in this Section 4 shall cease
to apply upon sixty (60) days’ prior written notice from the Holder to the Company.

5. [Intentionally Omitted]

6. Anti-Dilution Adjustments; Distributions; Other Events. The Exercise Price and the
number of Warrant Shares issuable hereunder shall be subject to adjustment from time to time as
provided in this Section 6. In the event that any adjustment of the Exercise Price required herein
results in a fraction of a cent, the Exercise Price shall be rounded up or down to the nearest one
hundredth of a cent.

(a) Subdivision or Combination of Common Stock. If the Company, at any time after the
Issue Date, subdivides (by any stock split, stock dividend, recapitalization, reorganization,
reclassification or otherwise) the outstanding shares of Common Stock into a greater number of
shares, then effective upon the close of business on the record date for effecting such
subdivision, the Exercise Price in effect immediately prior to such subdivision will be
proportionately reduced. If the Company, at any time after the Issue Date, combines (by reverse
stock split, recapitalization, reorganization, reclassification or otherwise) the outstanding
shares of Common Stock into a smaller number of shares, then, effective upon the close of business
on the record date for effecting such combination, the Exercise Price in effect immediately prior
to such combination will be proportionally increased.

(b) Distributions. If, at any time after the Issue Date, the Company declares or
makes any distribution of cash or any other assets (or rights to acquire such assets) to holders of
Common Stock, as a partial liquidating dividend or otherwise, including without limitation any
dividend or distribution to the Company’s shareholders in shares (or rights to acquire shares) of
capital stock of a subsidiary) (a “Distribution”), the Company shall deliver written notice of such
Distribution (a “Distribution Notice”) to the Holder at least thirty (30) days prior to the earlier
to occur of (i) the record date for determining shareholders entitled to such Distribution (the
“Record Date”) and (ii) the date on which such Distribution is made (the “Distribution Date”) (the
earlier of such dates being referred to as the “Determination Date”). In the Distribution Notice
to a Holder, the Company shall indicate whether the Company has elected (A) to deliver to such
Holder, upon any exercise of this Warrant after the Determination Date, the same amount and type of
assets being distributed in such Distribution as though the Holder were, on the Determination Date,
a holder of a number of shares of Common Stock into which this Warrant is exercisable as of such
Determination Date (such number of shares to be determined at the Exercise Price then in effect and
without giving effect to any limitations on such exercise) or (B) upon any exercise of this Warrant
on or after the Determination Date, to reduce the Exercise Price applicable to such exercise by
reducing the Exercise Price in effect on the Business Day immediately preceding the Record Date by
an amount equal to the fair market value of the assets to be distributed divided by the number of
shares of Common Stock as to which such Distribution is to be made, such fair market value to be
reasonably determined in good faith by the Company’s Board of Directors. If the Company does not
notify the Holders of its election pursuant to the preceding sentence on or prior to the
Determination Date, the Company shall be deemed to have elected clause (A) of the preceding
sentence.

(c) Adjustments; Additional Shares, Securities or Assets. In the event that at any
time, as a result of an adjustment made pursuant to this Section 6, the Holder of this Warrant
shall, upon exercise of this Warrant, become entitled to receive securities or assets (other than
Common Stock) then, wherever appropriate, all references herein to shares of Common Stock shall be
deemed to refer to and include such shares and/or other securities or assets; and thereafter the
number of such shares and/or other securities or assets shall be subject to adjustment from time to
time in a manner and upon terms as nearly equivalent as practicable to the provisions of this
Section 6. Any adjustment made pursuant to Section 6(a) that results in a decrease or an increase
in the Exercise Price shall also effect a proportional increase or decrease, as the case may be, in
the number of shares of Common Stock into which this Warrant is exercisable.

7. Fractional Interests.

No fractional shares or scrip representing fractional shares shall be issuable upon the
exercise of this Warrant, but instead shall be rounded up or down to the nearest whole share
amount.

8. Transfer of this Warrant.

The Holder may sell, transfer, assign, pledge or otherwise dispose of this Warrant, in whole
or in part, as long as such sale or other disposition is made pursuant to an effective registration
statement or an exemption from the registration requirements of the Securities Act. Upon such
transfer or other disposition (other than a pledge), the Holder shall deliver this Warrant to the
Company together with a written notice to the Company, substantially in the form of the Transfer
Notice attached hereto as Exhibit B (the “Transfer Notice”), indicating the person or persons to
whom this Warrant shall be transferred and, if less than all of this Warrant is transferred, the
number of Warrant Shares to be covered by the part of this Warrant to be transferred to each such
person. Within three (3) Business Days of receiving a Transfer Notice and the original of this
Warrant, the Company shall deliver to the each transferee designated by the Holder a Warrant or
Warrants of like tenor and terms for the appropriate number of Warrant Shares and, if less than all
this Warrant is transferred, shall deliver to the Holder a Warrant for the remaining number of
Warrant Shares.

9. Benefits of this Warrant.

This Warrant shall be for the sole and exclusive benefit of the Holder of this Warrant and
nothing in this Warrant shall be construed to confer upon any person other than the Holder of this
Warrant any legal or equitable right, remedy or claim hereunder.

10. Loss, theft, destruction or mutilation of Warrant.

Upon receipt by the Company of evidence of the loss, theft, destruction or mutilation of this
Warrant, and (in the case of loss, theft or destruction) of indemnity reasonably satisfactory to
the Company, and upon surrender of this Warrant, if mutilated, the Company shall execute and
deliver a new Warrant of like tenor and date.

11. Notice or Demands.

Any notice, demand or request required or permitted to be given by the Company or the Holder
pursuant to the terms of this Warrant shall be in writing and shall be deemed delivered (i) when
delivered personally or by verifiable facsimile transmission, unless such delivery is made on a day
that is not a Business Day, in which case such delivery will be deemed to be made on the next
succeeding Business Day, (ii) on the next Business Day after timely delivery to an overnight
courier and (iii) on the Business Day actually received if deposited in the U.S. mail (certified or
registered mail, return receipt requested, postage prepaid), addressed as follows:
