4.3 Within three (3) Business Days of receiving reimbursement from the DOE, ClearFuels shall
promptly pay over to Rentech such reimbursements made by the DOE with respect to the costs and
expenses Rentech has incurred in accordance with Section 4.2. Furthermore, in the event

into such bills of sale, assignments or other appropriate transfer documentation (including
assignment of any representations and warranties and indemnities provided from counterparties to
agreements) prepared by Rentech and reasonably acceptable to ClearFuels to transfer all right,
title and interest in, to and under such Project Assets to Rentech on an “as-is, where is” basis.
Such transfer to Rentech will be without any liability or recourse to ClearFuels and the parties
shall be responsible for all of their own transaction costs associated with any transfer, including
any federal, state and local taxes associated therewith.

4.5 Notwithstanding the foregoing, in the event that a Qualified Financing closes on or prior
to March 31, 2011 and ClearFuels fully makes payment to Rentech as required by Sections 4.3
and 5.1, Rentech shall enter into such bills of sale, assignments or other appropriate
transfer documentation to retransfer all right, title and interest in, to and under all Project
Assets back to ClearFuels on an “as-is, where-is” basis (pursuant to documentation reasonably
acceptable to Rentech). Such retransfer to ClearFuels will be without any liability or recourse to
Rentech and ClearFuels shall be responsible for all transaction costs associated with any
retransfer, including any federal, state and local taxes associated therewith.

4.6 From and after the date of this Agreement through the earlier of (a) the closing of a
Qualified Financing and (b) March 31, 2011, Rentech shall use commercially reasonable efforts to
cooperate with and support ClearFuels’ proposed offering of Series C Preferred Stock and shall
provide technical engineering support for the Project in a manner materially consistent with
Rentech’s past practices, including by assigning Harold Wright and Josh Pearson as project managers

4.7 After the date of this Agreement, at Rentech’s discretion, Rentech shall provide financial
and operational assistance to the development of the HECO Project, including by paying third party
development costs and providing project management assistance for such HECO Project. In the event
that the Closing occurs and HECO agrees (before or after the Closing) to enter into an Off-take
Agreement with the Project Entity, then, promptly following the Closing, ClearFuels and the
Shareholder Representative shall use commercially reasonable efforts to form the Project Entity and
to negotiate in good faith the terms of the Project LLC Agreement consistent with the terms of this
Agreement. Upon completion of such negotiations,

 

7

 

ClearFuels shall execute the Project LLC
Agreement and cause the Project Entity to issue the Profits Interest to the Shareholder Entity.
The Project LLC Agreement shall not require any holder of the Profits Interests (in its capacity as
such) to make capital contributions to the Project Entity, provided that the percentage
interest of such holder shall be subject to dilution on a pro rata basis with ClearFuels for any
capital contributions made to the Project Entity after the Financial Closing Date in accordance
with the Project LLC Agreement. The Shareholder LLC Agreement shall be consistent with the terms
of this Agreement, shall be in form and substance reasonably satisfactory to Rentech, and shall
require Rentech’s consent to any amendments, modifications or supplements thereto. The Shareholder
LLC Agreement shall prohibit direct or indirect transfers of membership interests in the
Shareholder Entity to any Person that is not a shareholder of ClearFuels as of the Closing Date
without the prior written consent of Rentech. The Shareholder LLC Agreement shall also require
that the Shareholder Entity generally provide Project Support Services as reasonably requested by
Project Entity. Nothing in this Agreement, the Project LLC Agreement or the Shareholder LLC
Agreement shall require Rentech or its affiliates to commence or continue the Project, which
Rentech may abandon at any time. Further, notwithstanding the foregoing, the Project Entity shall
not be required to issue the Profits Interest to the Shareholder Entity or any other Person, if the
Project Entity reasonably determines that the issuance of the Profits Interests constitutes the
sale of a security, unless the Shareholder Entity represents that it is an accredited investor (as
defined under Regulation D under the Securities Act of 1933, as amended (the “Securities Act”) and
provides other customary investment representations and warranties for transactions under Rule 506
of Regulation D, or unless the issuance is otherwise made in compliance with an applicable
exemption from the registration requirements of the Securities Act and all other applicable federal
and state securities laws (if any) that does not require the information required to be furnished
under Rule 502(b) of Regulation D; provided, however, that in the event that the offer and sale of
the Profits Interest is made pursuant to Rule 504 of Regulation D, then the Shareholder Entity
shall not be required to represent that it is an accredited investor. Following the Closing, the
Shareholder Representative shall have the right to enforce this Section 4.7. References in
this Section to ClearFuels shall include the Surviving Corporation following the Merger.

5. Partial Consideration for Rentech Support. In the event that a Qualified Financing
closes on or prior to March 31, 2011, then at such closing:

5.1 ClearFuels shall reimburse Rentech for all documented costs and expenses it has incurred
with respect to the portion of the Project Budget attributable to Budget Period 2 on a total
project basis (including, without limitation, payments made to vendors and Corporate Overhead
incurred by Rentech) and all Transaction Expenses incurred by Rentech on or before
the date the Qualified Financing closes, excluding any such costs and expenses that have
already been reimbursed by the DOE or ClearFuels as contemplated by this Agreement on or before
March 31, 2011 (the “Rentech Support Amounts”). In addition, at such closing, ClearFuels
shall pay to Rentech an administration fee with respect to each month in the period from October 1,
2010 through March 31, 2011. The administration fee for each such month shall equal the product of
(a) fifteen percent (15%) of the aggregate Rentech Support Amount for such month and (b) a
fraction, (i) the numerator of which is the number of days that have elapsed from the first day of
such month through the closing date of the Qualified Financing, and (ii) the denominator of which

5.2 ClearFuels shall issue to Rentech a warrant (the “Warrant”) to purchase a number
of shares of Financing Preferred Stock equal to (a) the Rentech Support Amount, divided by (b)
fifty percent (50%) of the Qualified Financing Price. The Warrant shall have an exercise price
equal to fifty percent (50%) of the Qualified Financing Price. The Warrants shall have a term that
expires five (5) years from the date of grant. The Warrant shall include a customary net share
settlement provision. The form and other terms of the Warrant shall be reasonably acceptable to
Rentech.

EXHIBIT A

TERMS AND CONDITIONS OF STOCK OPTION GRANT

     1. Grant. The Company hereby grants to the Participant named in the Notice of Grant
(“Participant”) an option (the “Option”) to purchase the number of Shares, as set forth in the
Notice of Grant, at the exercise price per Share set forth in the Notice of Grant (the “Exercise
Price”), subject to the terms and conditions in this Agreement and the Plan, which is incorporated
herein by reference. Subject to Section 20(c) of the Plan, in the event of a conflict between the
terms and conditions of the Plan and the terms and conditions of this Agreement, the terms and
conditions of the Plan will prevail.

          If designated in the Notice of Grant as an Incentive Stock Option (“ISO”), this Option is
intended to qualify as an Incentive Stock Option as defined in Section 422 of the Code. However,
if this Option is intended to be an Incentive Stock Option, to the extent that it exceeds the
$100,000 rule of Code Section 422(d) it will be treated as a Nonstatutory Stock Option (“NSO”).
Further, if for any reason this Option (or portion thereof) will not qualify as an ISO, then, to
the extent of such nonqualification, such Option (or portion thereof) will be regarded as a NSO
granted under the Plan. In no event will the Administrator, the Company or any Parent or
Subsidiary or any of their respective employees or directors have any liability to Participant (or
any other person) due to the failure of the Option to qualify for any reason as an ISO.

     2. Vesting Schedule. Except as provided in Section 3, the Option awarded by this
Agreement will vest in accordance with the vesting provisions set forth in the Notice of Grant.
Shares scheduled to vest on a certain date or upon the occurrence of a certain condition will not
vest in Participant in accordance with any of the provisions of this Agreement, unless Participant
will have been continuously a Service Provider from the Date of Grant until the date such vesting
occurs.

     3. Administrator Discretion. The Administrator, in its discretion, may accelerate the
vesting of the balance, or some lesser portion of the balance, of the unvested Option at any time,
subject to the terms of the Plan. If so accelerated, such Option will be considered as having
vested as of the date specified by the Administrator.

     4. Exercise of Option. This Option may be exercised only within the term set out in
the Notice of Grant, and may be exercised during such term only in accordance with the Plan and the
terms of this Agreement.

          This Option is exercisable by delivery of an exercise notice, in the form attached as
Exhibit B (the “Exercise Notice”) or in a manner and pursuant to such procedures as the
Administrator may determine, which will state the election to exercise the Option, the number of
Shares in respect of which the Option is being exercised (the “Exercised Shares”), and such other
representations and agreements as may be required by the Company pursuant to the provisions of the
Plan. The Exercise Notice will be completed by Participant and delivered to the Company. The
Exercise Notice will be accompanied by payment of the aggregate Exercise Price as to all Exercised
Shares together with any applicable tax withholding. This Option will be deemed to be exercised
upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate
Exercise Price.

     5. Method of Payment. Payment of the aggregate Exercise Price will be by any of the
following, or a combination thereof, at the election of Participant:

          (a) cash;

          (b) check;

          (c) consideration received by the Company under a formal cashless exercise program adopted by
the Company in connection with the Plan; or

          (d) surrender of other Shares which have a Fair Market Value on the date of surrender equal to
the aggregate Exercise Price of the Exercised Shares.

     6. Tax Obligations.

          (a) Tax Withholding. Notwithstanding any contrary provision of this Agreement, no
certificate representing the Shares will be issued to Participant, unless and until satisfactory
arrangements (as determined by the Administrator) will have been made by Participant with respect
to the payment of income, employment and other taxes which the Company determines must be withheld
with respect to such Shares. To the extent determined appropriate by the Company in its
discretion, it will have the right (but not the obligation) to satisfy

-2-

 

any tax withholding obligations by reducing the number of Shares otherwise deliverable to
Participant. If Participant fails to make satisfactory arrangements for the payment of any
required tax withholding obligations hereunder at the time of the Option exercise, Participant
acknowledges and agrees that the Company may refuse to honor the exercise and refuse to deliver the
Shares if such withholding amounts are not delivered at the time of exercise.

          (b) Notice of Disqualifying Disposition of ISO Shares. If the Option granted to
Participant herein is an ISO, and if Participant sells or otherwise disposes of any of the Shares
acquired pursuant to the ISO on or before the later of (i) the date two (2) years after the Grant
Date, or (ii) the date one (1) year after the date of exercise, Participant will notify the Company
in writing within thirty (30) days of such disposition. Participant agrees that Participant may be
subject to income tax withholding by the Company on the compensation income recognized by
Participant.

          (c) Code Section 409A. Under Code Section 409A, an option that vests after December
31, 2004 (or that vested on or prior to such date but which was materially modified after October
3, 2004) that was granted with a per Share exercise price that is determined by the Internal
Revenue Service (the “IRS”) to be less than the Fair Market Value of a Share on the date of grant
(a “Discount Option”) may be considered “deferred compensation.” A Discount Option may result in
(i) income recognition by Participant prior to the exercise of the option, (ii) an additional
twenty percent (20%) federal income tax, and (iii) potential penalty and interest charges. The
Discount Option may also result in additional state income, penalty and interest tax to the
Participant. Participant acknowledges that the Company cannot and has not guaranteed that the IRS
will agree that the per Share exercise price of this Option equals or exceeds the Fair Market Value
of a Share on the Date of Grant in a later examination. Participant agrees that if the IRS
determines that the Option was granted with a per Share exercise price that was less than the Fair
Market Value of a Share on the date of grant, Participant will be solely responsible for
Participant’s costs related to such a determination.

     7. Rights as Stockholder. Neither Participant nor any person claiming under or
through Participant will have any of the rights or privileges of a stockholder of the Company in
respect of any Shares deliverable hereunder unless and until certificates representing such Shares
will have been issued, recorded on the records of the Company or its transfer agents or registrars,
and delivered to Participant. After such issuance, recordation and delivery, Participant will have
all the rights of a stockholder of the Company with respect to voting such Shares and receipt of
dividends and distributions on such Shares.

     8. No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE
VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE
PROVIDER AT THE WILL OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING
PARTICIPANT) AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES
HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS
CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR
IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY
PERIOD, OR AT ALL, AND WILL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE
COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) TO TERMINATE PARTICIPANT’S
RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

     9. Termination Period. This Option will be exercisable for three (3) months after
Participant ceases to be a Service Provider, unless such termination is due to Participant’s death
or Disability, in which case this Option will be exercisable for twelve (12) months after
Participant ceases to be a Service Provider. Notwithstanding the foregoing sentence, in no event
may this Option be exercised after the Term/Expiration Date as provided above and may be subject to
earlier termination as provided in Section 20(c) of the Plan.

     10. Address for Notices. Any notice to be given to the Company under the terms of
this Agreement will be addressed to the Company at Oplink Communications, Inc., 46335 Landing
Parkway, Fremont, CA 94538, or at such other address as the Company may hereafter designate in
writing or electronically.

     11. Grant is Not Transferable. This Option may not be transferred in any manner
otherwise than by will or by the laws of descent or distribution and may be exercised during the
lifetime of Participant only by Participant.

     12. Binding Agreement. Subject to the limitation on the transferability of this grant
contained herein, this Agreement will be binding upon and inure to the benefit of the heirs,
legatees, legal representatives, successors and assigns of the parties hereto.

-3-

 

     13. Additional Conditions to Issuance of Stock. If at any time the Company will
determine, in its discretion, that the listing, registration or qualification of the Shares upon
any securities exchange or under any state or federal law, or the consent or approval of any
governmental regulatory authority is necessary or desirable as a condition to the issuance of
Shares to Participant (or his or her estate), such issuance will not occur unless and until such
listing, registration, qualification, consent or approval will have been effected or obtained free
of any conditions not acceptable to the Company. Where the Company determines that the delivery of
the payment of any Shares will violate federal securities laws or other applicable laws, the
Company will defer delivery until the earliest date at which the Company reasonably anticipates
that the delivery of Shares will no longer cause such violation. The Company will make all
reasonable efforts to meet the requirements of any such state or federal law or securities exchange
and to obtain any such consent or approval of any such governmental authority. Assuming such
compliance, for income tax purposes the Exercised Shares will be considered transferred to
Participant on the date the Option is exercised with respect to such Exercised Shares.

     14. Plan Governs. This Agreement is subject to all terms and provisions of the Plan.
In the event of a conflict between one or more provisions of this Agreement and one or more
provisions of the Plan, the provisions of the Plan will govern. Capitalized terms used and not
defined in this Agreement will have the meaning set forth in the Plan.

     15. Administrator Authority. The Administrator will have the power to interpret the
Plan and this Agreement and to adopt such rules for the administration, interpretation and
application of the Plan as are consistent therewith and to interpret or revoke any such rules
(including, but not limited to, the determination of whether or not any Shares subject to the
Option have vested). All actions taken and all interpretations and determinations made by the
Administrator in good faith will be final and binding upon Participant, the Company and all other
interested persons. No member of the Administrator will be personally liable for any action,
determination or interpretation made in good faith with respect to the Plan or this Agreement.

     16. Electronic Delivery. The Company may, in its sole discretion, decide to deliver
any documents related to Options awarded under the Plan or future Options that may be awarded under
the Plan by electronic means or request Participant’s consent to participate in the Plan by
electronic means. Participant hereby consents to receive such documents by electronic delivery and
agrees to participate in the Plan through any on-line or electronic system established and
maintained by the Company or another third party designated by the Company.

     17. Captions. Captions provided herein are for convenience only and are not to serve
as a basis for interpretation or construction of this Agreement.

     18. Agreement Severable. In the event that any provision in this Agreement will be
held invalid or unenforceable, such provision will be severable from, and such invalidity or
unenforceability will not be construed to have any effect on, the remaining provisions of this
Agreement.

     19. Modifications to the Agreement. This Agreement constitutes the entire
understanding of the parties on the subjects covered. Participant expressly warrants that he or
she is not accepting this Agreement in reliance on any promises, representations, or inducements
other than those contained herein. Modifications to this Agreement or the Plan can be made only in
an express written contract executed by a duly authorized officer of the Company. Notwithstanding
anything to the contrary in the Plan or this Agreement, the Company reserves the right to revise
this Agreement as it deems necessary or advisable, in its sole discretion and without the consent
of Participant, to comply with Code Section 409A or to otherwise avoid imposition of any additional
tax or income recognition under Code Section 409A in connection to this Option.

     20. Amendment, Suspension or Termination of the Plan. By accepting this Award,
Participant expressly warrants that he or she has received an Option under the Plan, and has
received, read and understood a description of the Plan. Participant understands that the Plan is
discretionary in nature and may be amended, suspended or terminated by the Company at any time.

     21. Governing Law. This Agreement will be governed by the laws of the State of
California, without giving effect to the conflict of law principles thereof. For purposes of
litigating any dispute that arises under this Option or this Agreement, the parties hereby submit
to and consent to the jurisdiction of the State of California, and agree that such litigation will
be conducted in the courts of Alameda County, California, or the federal courts for the United
States for the Northern District of California, and no other courts, where this Option is made
and/or to be performed.
