Babatunde A. Otulana, M.D.

Dear Tunde:

This letter sets forth the substance of the separation agreement (the
“Agreement”) that Aradigm Corporation (the “Company”) is offering to you to aid
in your employment transition.

  1.   Separation. Your last day of work with the Company and your employment
termination date will be December 31, 2008 (the “Separation Date”).

  2.   Accrued Salary and Paid Time Off. On the Separation Date, the Company
will pay all accrued salary, and all accrued and unused vacation earned through
the Separation Date, subject to standard payroll deductions and withholdings.
You are entitled to these payments regardless of whether or not you sign this
Agreement.

  3.   Severance Benefits. The Company will make severance payments to you in
the amount of $16,666.67 per month paid over one year following the Separation
Date. These payments will be made on the Company’s ordinary payroll dates, and
will be subject to standard payroll deductions and withholdings.

  4.   Health Insurance. To the extent provided by the federal COBRA law or, if
applicable, state insurance laws, and by the Company’s current group health
insurance policies, you and your dependents will be eligible to continue your
group health insurance benefits. Later, you may be able to convert to an
individual policy through the provider of the Company’s health insurance, if you
wish. If you elected COBRA, the Company will pay COBRA premiums on your behalf
and on behalf of your dependents up to a maximum of twelve (12) months or until
you become eligible for group health insurance coverage through a new employer
(whichever comes first). You must promptly notify the Company in writing if you
become eligible for group health insurance coverage through a new employer
during the twelve (12) months following the Separation Date.

  5.   Other Compensation or Benefits. Except with respect to any fees earned by
you pursuant to that certain Consulting Agreement for Independent Contractors
between you and the Company dated effective January 1, 2009 and that certain
International Scientific Advisory Agreement between you and the Company dated
effective January 1, 2009, you acknowledge that, except as expressly provided in
this Agreement, you will not receive any additional compensation, severance or
benefits after the Separation Date, with the sole exception of any benefit the
right to which has vested under the express terms of a Company benefit plan
document. Notwithstanding the foregoing any stock options and/or restricted
stock awards previously granted to you, including, without limitation, the
continued vesting thereof, will continue to be governed by the plan documents
pursuant to which they were granted.

  6.   Expense Reimbursement. You agree that, within ten (10) days of the
Separation Date, you will submit your final documented expense reimbursement
statement reflecting all business expenses you incurred through the Separation
Date, if any, for which you seek reimbursement. The Company will reimburse you
for these expenses pursuant to its regular business practice.

  7.   Return of Company Property. You agree that, by the Separation Date, you
shall return to the Company all Company documents (and all copies thereof) and
other Company property in your possession or control, including, but not limited
to: Company files, notes, memoranda, correspondence, agreement, draft documents,
notebooks, logs, drawings, records, plans, proposals, reports, forecasts,
financial information, sales and marketing information, research and development
information, personnel information, specifications, computer-recorded
information, tangible property and equipment, credit cards, entry cards,
identification badges, and keys; and any materials of any kind that contain or
embody any proprietary or confidential information of the Company (and all
reproductions thereof in whole or in part).

  8.   Proprietary Information Obligations. You acknowledge your continuing
obligations under your Proprietary Information and Inventions Agreement (a copy
of which was provided to you separately).

  9.   Nondisparagement. Both you and the Company’s officers agree not to
disparage the other party, and the other party’s officers, directors, employees,
shareholders and agents, in any manner likely to be harmful to them or their
business, business reputation or personal reputation; provided that both you and
the Company will respond accurately and fully to any question, inquiry or
request for information when required by legal process.

  10.   Release. In exchange for the severance payments, and other consideration
under this Agreement to which you would not otherwise be entitled, you hereby
generally and completely release the Company and its directors, officers,
employees, shareholders, partners, agents, attorneys, predecessors, successors,
parent or subsidiary entities, insurers, affiliates and assigns from any and all
claims, liabilities and obligations, both known and unknown, that arise out of
or are in any way related to events, acts, conduct, or omissions prior to or on
the date you sign this Agreement. This general release includes, but is not
limited to: (1) all claims arising out of or in any way related to your
employment with the Company or the termination of that employment; (2) all
claims related to your compensation or benefits from the Company, including
salary, bonuses, commissions, vacation pay, expense reimbursements, severance
pay, fringe benefits, stock, stock options or any other ownership interests in
the Company; (3) all claims for breach of contract, wrongful termination or
breach of the implied covenant of good faith and fair dealing; (4) all tort
claims, including claims for fraud, defamation, emotional distress and discharge
in violation of public policy; and (5) all federal, state, and local statutory
claims, including claims for discrimination, harassment, retaliation, attorneys’
fees, or other claims arising under the federal Civil Rights Act of 1964 (as
amended), the federal Americans with Disabilities Act of 1990, or the California
Fair Employment and Housing Act (as amended).

  11.   Release of ADEA Claims. You hereby acknowledge that you are knowingly
and voluntarily waiving and releasing any rights you may have under the ADEA,
and that the consideration given for the foregoing waiver is in addition to
anything of value to which you were already entitled. You have been advised by
this writing, as required by the ADEA that: (a) your waiver and release do not
apply to any claims that may arise after your signing of this Agreement; (b) you
should consult with an attorney prior to executing this release; (c) you have
twenty-one (21) days within which to consider this release (although you may
choose to voluntarily execute this release earlier); (d) you have seven (7) days
following the execution of this release to revoke the Agreement; and (e) this
Agreement will not be effective until the eighth day after this Agreement has
been signed both by you and by the Company (“Effective Date”).

      12.

1

Section 1542 Waiver. In granting the release herein, which includes claims which
may be unknown to you at present, you acknowledge that you have read and
understand Section 1542 of the California Civil Code: “A general release does
not extend to claims which the creditor does not know or suspect to exist in his
favor at the time of executing the release, which if known by him must have
materially affected his settlement with the debtor.” You hereby expressly waive
and relinquish all rights and benefits under that section and any law of any
jurisdiction of similar effect with respect to your release of any unknown or
unsuspected claims herein.

  13.   Miscellaneous. This Agreement, including Exhibit A, constitutes the
complete, final and exclusive embodiment of the entire agreement between you and
the Company with regard to this subject matter. It is entered into without
reliance on any promise or representation, written or oral, other than those
expressly contained herein, and it supersedes any other such promises or
representations. This Agreement may not be modified or amended except in a
writing signed by both you and a duly authorized officer of the Company. This
Agreement will bind the heirs, personal representatives, successors and assigns
of both you and the Company, and insure to the benefit of both you and the
Company, their heirs, successors and assigns. The failure to enforce any breach
of this Agreement shall not be deemed to be a waiver of any other or subsequent
breach. For purposes of construing this Agreement, any ambiguities shall not be
construed against either party as the drafter. If any provision of this
Agreement is determined to be invalid or unenforceable, in whole or in part,
this determination will not affect any other provision of this Agreement and the
provision in question will be modified by the court so as to be rendered
enforceable in a manner consistent with the intent of the parties insofar as
possible. This Agreement will be deemed to have been entered into and will be
construed and enforced in accordance with the laws of the State of California as
applied to contacts made and to be performed entirely within California. This
agreement may be executed in counterparts which shall be deemed to be part of
one original, and facsimile signatures shall be equivalent to original
signatures.

If this Agreement is acceptable to you, please sign below and return the
original to me.

I wish you good luck in your future endeavors.

Sincerely,

ARADIGM CORPORATION
