Dear Susan:

I am pleased to offer you a position with Transcept Pharmaceuticals (the
“Company”) as Vice President, Corporate Development. The position will be
located at our offices located at 1003 W. Cutting Blvd., Suite 110, Pt.
Richmond, California. If you decide to join us you will receive a monthly salary
of Twenty-Two Thousand Eighty-Three Dollars and Thirty-Three cents ($22,083.33),
which will be paid semi-monthly in accordance with the Company’s normal payroll
procedures.

You will also be eligible to participate in the executive bonus program with a
target bonus of up to 25% of your base salary. At Transcept our salary merit
increases and potential bonus amounts, if any, are based upon the assumption
that an employee has provided services to the Company for the entire calendar
year. Therefore, if you join Transcept at any time between January 1 and
November 1 of any calendar year, your potential salary merit increase and
potential bonus, if either is awarded, will be pro-rated for the actual amount
of service you provide during that calendar year. If you leave at any time
during a year, you will not be eligible for any pro-rata amount of your unearned
target bonus for that year. Bonus payments will be subject to required
deductions and withholdings. The Company shall have the sole discretion to
determine whether you have earned any bonus set forth in this paragraph and, if
so, the amount of any such bonus.

As an employee, you are also eligible to receive certain employee benefits that
currently include health, dental, life and vision insurance. You should note
that the Company may modify salaries and benefits from time to time as it deems
necessary.

In addition, if you decide to join us, it will be recommended at the first
meeting of the Company’s Board of Directors following your start date that the
Company grant you an option to purchase 375,000 shares of the Company’s Common
Stock at a price per share equal to the fair market value per share of the
Common Stock on the date of grant, as determined by the Company’s Board of
Directors. 25% of the Shares subject to the option shall vest 12 months after
the date your vesting begins and no shares shall vest before such date and no
rights to any vesting shall be earned or accrued prior to such date and the
remaining shares shall vest monthly over the next 36 months in equal monthly
amounts subject to your continuing employment with the Company, provided,
however, that if the Company is acquired in a transaction in which the
shareholders of the Company receive cash or publicly traded securities and your
employment is involuntarily terminated by the Company without Cause (“Cause”
shall mean (i) failure to substantially perform your duties as assigned to you,
(ii) a material act of fraud or dishonesty that is injurious to the Company,
(iii) a breach of a material provision of this Letter or the At Will Employment,
Confidential Information, Invention Assignment, and Arbitration Agreement,
(iv) a violation of the federal or state law or regulations applicable to the
business of the Company, or

(v) conviction of, or a plea of “no contest” to a felony) within twelve
(12) months after the date of closing of such acquisition, all shares subject to
such options shall immediately become exercisable. This option grant shall be
subject to the terms and conditions of the Company’s Stock Option Plan and Stock
Option Agreement. Over time, additional performance-based stock option grants
may be made available in the sole discretion of the Company.

The Company is excited about the prospect of you joining our team, and we look
forward to a beneficial and fruitful relationship. Nevertheless, you should be
aware that your employment with the Company is for no specified period and
constitutes at-will employment. As a result, you are free to resign at any time,
for any reason or for no reason. Similarly, the Company is free to conclude its
employment relationship with you at any time, with or without cause, and with or
without notice. We request that, in the event of resignation, you give the
Company at least two-week’s notice.

To comply with its Drug Enforcement Administration license, the Company conducts
background investigations and reference checks on all of its potential
employees. Your job offer, or employment, is contingent upon the clearance of
such a background investigation and reference checks.

For purposes of federal immigration law, you will be required to provide to the
Company documentary evidence of your identity and eligibility for employment in
the United States. Such documentation must be provided to us within three
(3) business days of your date of hire, or our employment relationship with you
may be terminated.

We also ask that, if you have not already done so, you disclose to the Company
any and all agreements relating to your prior employment that may affect your
eligibility to be employed by the Company or limit the manner in which you may
be employed. It is the Company’s understanding that any such agreements will not
prevent you from performing the duties of your position and you represent that
such is the case. Moreover, you agree that, during the term of your employment
with the Company, you will not engage in any other employment, occupation,
consulting or other business activity directly related to the business in which
the Company is now involved or becomes involved during the term of your
employment, nor will you engage in any other activities that conflict with your
obligations to the Company. Similarly, you agree not to bring any third-party
confidential information to the Company, including that of your former employer,
and that in performing your duties for the Company, you will not in any way
utilize any such information.

As you know, Transcept is involved in an industry that is highly competitive and
that changes quickly. Thus, although the position we are offering is as its Vice
President, Corporate Development, Transcept may change your position and/or your
duties at any time, with or without notice. As with all of our employees, your
employment is also subject to our general employment policies, many of which are
described in our Employee Handbook. As a Company employee, you will be expected
to abide by company rules and standards. You will be specifically required to
sign an acknowledgment that you have read and that you understand the Company’s
rules of conduct, which are included in the Company Handbook.

As a condition of your employment, you will also be required to sign and comply
with an At-WilL Employment, Confidential Information, Invention Assignment, and
Arbitration Agreement which requires, among other provisions, the assignment of
patent rights to any invention made during your employment at the Company, and
non-disclosure of proprietary

Dear Susan,

This side letter (“Side Letter”) to the offer letter, dated as of June 4, 2008
(the “Offer Letter”) is between you and Transcept Pharmaceuticals, Inc. (the
“Company”). Capitalized terms used in this Side Letter have the same meaning
they have in the Offer Letter.

As you know, the Company is negotiating an agreement and plan of merger and
reorganization with [N Inc.], a Delaware corporation (“Pivot”) and Pivot
Acquisition, Inc., a Delaware corporation whereby the Company would become a
wholly-owned subsidiary of Pivot (the “Transaction”). You understand that the
Transaction is intended to be a means of obtaining financing for the Company and
is not intended to be treated as an acquisition of the Company. You acknowledge
that you may benefit from the Transaction in your capacity as an employee of the
Company and through your stock option to acquire shares of Company common stock
and other Company equity you may own. This Side Letter is intended to confirm
and clarify our mutual understanding. Accordingly, both you and the Company
(including any successor entity) agree as follows:

 

  •  

Stock Option Treatment as a Result of the Transaction. The consummation of the
Transaction shall not constitute an event pursuant to which the Company will be
acquired and the Company shareholders receive cash or publicly traded
securities. For purposes of the Offer Letter, you will not, as a result of the
Transaction, receive (i) accelerated vesting of your stock option granted to you
in accordance with your Offer Letter (the fV) or (ii) a severance payment in the
event you are terminated without Cause within twelve (12) months following the
consummation of the Transaction.

This Side Letter does not affect the “at-will” status of your employment with
the Company (consistent with the Offer Letter) and the Company is free to
terminate its employment relationship with you at any time, subject to any
notice requirement set forth in your Offer Letter.

You agree that to the extent this Side Letter is inconsistent with the
provisions of the Offer Letter, the Side Letter will supersede the Offer Letter
and control.

This Side Letter, together with the Offer Letter, to the extent not amended by
this letter represents the entire agreement and understanding you and the
Company as to the subject matter herein and supersedes all prior or
contemporaneous agreements whether written or oral. No waiver,

alteration or modification of any provisions of this Side Letter will be binding
unless in writing and signed by you and the Company.

This Side Letter shall be governed by and construed in accordance with the laws
of the California, regardless of its conflicts of laws provisions.

Please sign below to indicate your agreement to the terms of this Side Letter.
