sale price of the Common Stock on the principal securities exchange or trading market where the
Common Stock is listed or traded as reported by Bloomberg, or, if no volume weighted average sale
price is reported for the Common Stock, then the last closing trade price of the Common Stock as
reported by Bloomberg, or, if no last closing trade price is reported for the Common Stock by
Bloomberg, the average of the bid prices of any market makers for the Common Stock in the over the
counter market maintained by the National Association of Securities Dealers or in the “pink sheets”
maintained by the National Quotation Bureau, Inc. If the Volume Weighted Average Price cannot be
calculated for the Common Stock on such date in the manner provided above, the Volume Weighted
Average Price shall be the fair market value as mutually determined by the Borrower and Deerfield
Private Design. If any of the Lenders or any transferee of a Warrant delivers to the Borrower the
written notice referred to in Section 1 of the Warrant annexed hereto as Exhibit C-1, then all
Warrants thereafter issued to such Lender or such transferee shall be in the form annexed hereto at
Exhibit C-2.

Document, brought in the
courts of the State of New York or in the United States District
Court for the Southern District of New York, and any claim that any such action, suit
or other proceeding brought in any such court has been brought in an inconvenient forum.




     (c) The Borrower hereby waives any and all rights to demand a trial by jury in any
action, suit or other proceeding arising out of any Financing Document or the transactions
contemplated by any Financing Document.




     (d) To the extent that the Borrower or Deerfield Private Design may, in any suit,
action or other proceeding brought in any court arising out of or in connection with any
Financing Document, be entitled to the benefit of any provision of law requiring the
Borrower or the Lenders, as applicable, in such suit, action or other proceeding to post
security for the costs of the Borrower or Deerfield Private Design, as applicable, or to
post a bond or to take similar action, the Borrower and Deerfield Private Design hereby
irrevocably waive such benefit, in each case to the fullest extent now or hereafter
permitted under any applicable laws.



     Section 7.5 Successor and Assigns. This Agreement shall bind and inure to the benefit of the
respective successors and assigns of the Parties, except that the Borrower may not assign or
otherwise transfer all or any part of its rights or obligations under this Agreement without the
prior written consent of Deerfield Private Design. Notwithstanding the foregoing, nothing herein
shall be deemed to limit or otherwise restrict a merger, reorganization or sale of substantially
all of the assets of Borrower.



     Section 7.6 Entire Agreement. The Financing Documents contain the entire understanding of the
Parties with respect to the matters covered thereby and supersede any and all other written and
oral communications, negotiations, commitments and writings with respect thereto. The provisions
of this Agreement may be waived, modified, supplemented or amended only by an instrument in writing
signed by the authorized officer of each Party; provided, however, that any provision hereof that
is solely for the Lenders’ benefit may be waived by written instrument signed by an authorized
officer of such Lender.



     Section 7.7 Amendments. Any provision of this Agreement may be amended or waived if, but only
if, such amendment or waiver is in writing and is signed by the Borrower and Deerfield Private
Design.



     Section 7.8 Severability. If any one or more of the provisions contained in this Agreement
shall be invalid, illegal or unenforceable in any respect under any law, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or impaired thereby.
The Parties shall endeavor in good faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which comes as close as
possible to that of the invalid, illegal or unenforceable provisions.



     Section 7.9 Counterparts. This Agreement may be executed in several counterparts, and by each
Party on separate counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same agreement.

     Section 7.10 Survival.




     (a) This Agreement and all agreements, representations and warranties made in this
Agreement, and in any document, certificate or statement delivered pursuant thereto or in
connection therewith shall be considered to have been relied upon by the other Parties and
shall survive the execution and delivery of this Agreement and the making of the Loan
hereunder regardless of any investigation made by any such other Party or on its behalf, and
shall continue in force until all amounts payable under the this Agreement shall have been
fully paid in accordance with the provisions hereof and thereof, and the Lenders shall not
be deemed to have waived, by reason of making the Loan, any Default that may arise by reason
of such representation or warranty proving to have been false or misleading, notwithstanding
that the Lenders may have had notice or knowledge of any such Default or may have had notice
or knowledge that such representation or warranty was false or misleading at the time any
Disbursement was made hereunder.




     (b) The obligations of the Borrower under Sections 2.7 and 2.8 and the obligations of
the Borrower and the Lenders under this Article VII hereof shall survive and remain in full
force and effect regardless of the consummation of the transactions contemplated hereby, the
repayment of the Loan, or the termination of this Agreement or any provision hereof.



     Section 7.11 Waiver. Neither the failure of, nor any delay on the part of, any Party in
exercising any right, power or privilege hereunder, or under any agreement, document or instrument
mentioned herein, shall operate as a waiver thereof, nor shall any single or partial exercise of
any right, power or privilege hereunder, or under any agreement, document or instrument mentioned
herein, preclude other or further exercise thereof or the exercise of any other right, power or
privilege; nor shall any waiver of any right, power, privilege or default hereunder, or under any
agreement, document or instrument mentioned herein, constitute a waiver of any other right, power,
privilege or default or constitute a waiver of any default of the same or of any other term or
provision. No course of dealing and no delay in exercising, or omission to exercise, any right,
power or remedy accruing to the Lenders upon any default under this Agreement, or any other
agreement shall impair any such right, power or remedy or be construed to be a waiver thereof or an
acquiescence therein; nor shall the action of the Lenders in respect of any such default, or any
acquiescence by it therein, affect or impair any right, power or remedy of the Lenders in respect
of any other default. All rights and remedies herein provided are cumulative and not exclusive of
any rights or remedies otherwise provided by law.



     Section 7.12 Indemnity.




     (a) The Parties shall, at all times, indemnify and hold each other harmless (the
“Indemnity”) and each of their respective directors, members, officers, employees,
agents, counsel and advisors (each, an “Indemnified Person”) in connection with any
losses, claims (including the cost of defending against such claims), damages, liabilities,
penalties, or other expenses arising out of, or relating to, this Agreement, the extension
of credit hereunder or the Loan, the use or intended use of the Loan or any investment or

23









 











proposed investment, which an Indemnified Person may incur or to which an Indemnified Person
may become subject (each, a “Loss”). The Indemnity shall not apply
to the extent that a court or arbitral tribunal with jurisdiction over the subject
matter of the Loss, and over the Lenders or the Borrower, as applicable, and such other
Indemnified Person that had an adequate opportunity to defend its interests, determines that
such Loss resulted from the gross negligence or willful misconduct of the Indemnified
Person, which determination results in a final, non-appealable judgment or decision of a
court or tribunal of competent jurisdiction. The Indemnity is independent of and in
addition to any other agreement of any Party under any Financing Document to pay any amount
to the Lenders or the Borrower, as applicable, and any exclusion of any obligation to pay
any amount under this subsection shall not affect the requirement to pay such amount under
any other section hereof or under any other agreement.




     (b) Without prejudice to the survival of any other agreement of any of the Parties
hereunder, the agreements and the obligations of the Parties contained in this Section 7.12
shall survive the termination of each other provision hereof and the payment of all amounts
payable to the Lenders hereunder.



     Section 7.13 No Usury. This Agreement is hereby expressly limited so that in no contingency
or event whatsoever, whether by reason of acceleration or otherwise, shall the amount paid or
agreed to be paid to the Lenders for the Loan exceed the maximum amount permissible under
applicable law. If from any circumstance whatsoever fulfillment of any provision hereof, at the
time performance of such provision shall be due, shall involve transcending the limit of validity
prescribed by law, then, ipso facto, the obligation to be fulfilled shall be reduced to the limit
of such validity, and if from any such circumstance the Lenders shall ever receive anything which
might be deemed interest under applicable law, that would exceed the highest lawful rate, such
amount that would be deemed excessive interest shall be applied to the reduction of the principal
amount owing on account of the Loan, or if such deemed excessive interest exceeds the unpaid
balance of principal of the Loan, such deemed excess shall be refunded to the Borrower. All sums
paid or agreed to be paid to the Lenders for the Loan shall, to the extent permitted by applicable
law, be deemed to be amortized, prorated, allocated and spread throughout the full term of the Loan
until payment in full so that the deemed rate of interest on account of the Loan is uniform
throughout the term thereof. The terms and provisions of this paragraph shall control and
supersede every other provision of this Agreement and the Note.



     Section 7.14 Further Assurances. From time to time, the Borrower shall perform any and all
acts and execute and deliver to Deerfield Private Design such additional documents as may be
necessary or as requested by Deerfield Private Design to carry out the purposes of this Agreement
or any or to preserve and protect the Lenders’ rights as contemplated therein.

               (a) The Subordinating Creditor shall not accelerate the maturity or payment of any

of Bankruptcy, the following provisions shall apply upon the occurrence of any Event of Bankruptcy:



               (a) Any payment or distribution of assets of Dynavax of any kind or character with respect to
the Subordinated Debt that occurs after any Event of Bankruptcy, whether such payment or

entity making such payment or distribution, directly to the Lenders for application to the payment
of the Senior Debt, to the extent necessary to pay the Senior Debt in full in cash after giving

authorize and direct Dynavax, or any receiver, liquidator, custodian, conservator, trustee or other
entity making any payment or distribution with respect to Dynavax or any of its assets, to make
such payment or distribution directly to the Lenders.

action or proceeding, if such objection is based (in whole or in part) on a lack of adequate
protection of the claims of the Lenders, (C) the entry of any cash collateral order supported by
the Lenders, (D) the entry of any financing order involving the Lenders (whether under §364 of the
Bankruptcy Code or otherwise).
