The Company has prepared and filed in conformity with the requirements of the Securities Act
of 1933, as amended (the “Securities Act”), and the published rules and regulations thereunder (the

amended and/or supplemented to the date of this Agreement, including the Base Prospectus. If the
Company has filed an abbreviated registration statement to register additional Shares pursuant to
Rule 462(b) under the Rules (the “462(b) Registration Statement”), then any reference herein to the
Registration Statement shall also be deemed to include such 462(b) Registration Statement. The
prospectus supplement relating to the Shares in the form in which it will be filed with the
Commission pursuant to and in accordance with Rule 424(b) under the Securities Act is hereinafter
referred to as the “Prospectus Supplement.” The term “Prospectus” as used in this Agreement means
the Base Prospectus together with the Prospectus Supplement. As used herein, the terms “Base
Prospectus,” “Prospectus,” “Registration Statement,” “Rule 462 Registration Statement,” and
“Prospectus Supplement” shall include any documents incorporated by reference therein, and any
reference to any amendment or supplement to the Registration Statement or the Prospectus shall be
deemed to refer to and include any document filed under the Securities Exchange Act of 1934, as

Commission and on or before the Closing Date, which documents are deemed to be incorporated therein
by reference.

In connection with their duties as Placement Agents, the Company hereby confirms that the
Placement Agents are authorized to distribute the Prospectus (as from time to time amended or
supplemented if the Company furnishes amendments or supplements thereto to the Placement Agents).

Prospectus and any supplement thereto pursuant to Rule 424(b) of the Rules has been or will be made
in the manner and within the time period required by such Rule 424(b).

(c) The documents incorporated by reference in the Registration Statement and the Prospectus,
at the time they became effective or were filed with the Commission, as the case may be, complied
in all material respects with the requirements of the Securities Act or the Exchange Act, as
applicable, and the rules and regulations of the Commission thereunder, and none of such documents
contained an untrue statement of a material fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading, and any further documents so filed and
incorporated by reference in the Registration Statement and the Prospectus, when such documents
become effective or are filed with the Commission, as the case may be, will conform in all material
respects to the requirements of the Securities Act or the Exchange Act, as applicable, and the
rules and regulations of the Commission thereunder and will not contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they are made, not misleading.

(d) The financial statements of the Company (including all notes and schedules thereto)
included or incorporated by reference in the Registration Statement and Prospectus present fairly
the financial position of the Company and its consolidated subsidiaries at the dates indicated and
the statement of operations, stockholders’ equity and cash flows of the Company and its
consolidated subsidiaries for the periods specified; and such financial statements and related
schedules and notes thereto, and the unaudited financial information filed with the Commission as
part of the Registration Statement, comply as to form with the applicable accounting requirements
under the Securities Act and have been prepared in conformity with generally accepted accounting
principles, consistently applied throughout the periods involved. The summary and selected
financial data included in the Prospectus  present fairly the information shown therein as

consistent with the consolidated financial statements set forth in the Prospectus and other
financial information.

Registration Statement, are and, during the periods covered by their reports, were independent
registered public accountants as required by the Securities Act and the Rules.

(f) The Company and each of its subsidiaries is duly organized, validly existing and in good
standing under the laws of their respective jurisdictions of incorporation or organization. The
Company and each of its subsidiaries is duly qualified to do business and is in good standing as a
foreign corporation in each jurisdiction in which the nature of the business conducted by it or
location of the assets or properties owned, leased or licensed by it requires such qualification,
except for such jurisdictions where the failure to so qualify individually or in the aggregate
would not have a material adverse effect on the assets, properties, condition, financial or
otherwise, or in the capitalization, results of operations, business affairs or business prospects
of the Company and its subsidiaries considered as a whole (a “Material Adverse Effect”); and to the
Company’s knowledge, no proceeding has been instituted in any such jurisdiction revoking, limiting
or curtailing, or seeking to revoke, limit or curtail, such power and authority or qualification.

(g) The Company and each of its subsidiaries has all requisite corporate power and authority,
and all necessary authorizations, approvals, consents, orders, licenses, certificates and permits
of and from all governmental or regulatory bodies or any other person or entity (collectively, the
“Permits”), to own, lease and license its assets and properties and conduct its business, all of
which are valid and in full force and effect, except where the lack of such Permits, individually
or in the aggregate, would not have a Material Adverse Effect. The Company and each of its
subsidiaries has fulfilled and performed in all material respects all of its material obligations
with respect to such Permits and no event has occurred that allows, or after notice or lapse of
time would allow, revocation or termination thereof or results in any other material impairment of
the rights of the Company thereunder. Except as may be required under the Securities Act and state
and foreign Blue Sky laws, no other Permits are required to enter into, deliver and perform this
Agreement and to issue and sell the Shares.

(h) The Company and each of its subsidiaries owns or possesses legally enforceable rights to
use all patents, patent rights, inventions, collaborative research agreements, trademarks,
trademark applications, trade names, service marks, copyrights, copyright applications, licenses,

to the conduct of its business as described in the Registration Statement and the Prospectus.
Except as set forth in the Prospectus, (a) there are no material rights of third parties to any
such Intangibles; (b) there is no material infringement by third parties of any such Intangibles;
(c) there is no pending or threatened action, suit, proceeding or claim by others challenging the
Company’s rights in or to any such Intangibles, and the Company and each subsidiary is unaware of
any facts which would form a reasonable basis for any such claim; (d) to the knowledge of the
Company, there is no pending or threatened action, suit, proceeding or claim by others challenging
the validity or scope of any such Intangibles, and the Company and each subsidiary is unaware of
any facts which would form a reasonable basis for any such claim; (e) to the knowledge of the
Company, there is no pending or threatened action, suit, proceeding or claim by others that the
Company or any subsidiary infringes or otherwise violates any patent, trademark, copyright, trade
secret or other proprietary rights of others, and the Company and each subsidiary is unaware of any
other fact which would form a reasonable basis for any such claim; (f) to the knowledge of the
Company, there is no U.S. patent or published U.S. patent application which contains claims that
dominate or may dominate any Intellectual Property described in the Prospectus as being owned by or
licensed to the Company or any subsidiary or that interferes with the issued or pending claims of
any such Intangibles; and (g) there is no prior art of which the Company or any subsidiary is aware
that may render any U.S. patent held by the Company invalid or any U.S. patent application held by
the Company or any subsidiary unpatentable which has not been disclosed to the U.S. Patent and
Trademark Office.

(i) Except as set forth in the Prospectus, the Company and each of its subsidiaries has good
and marketable title in fee simple to all real property, and good and marketable title to all other
property owned by it, in each case free and clear of all liens, encumbrances, claims, security
interests and defects, except such as would not have a Material Adverse Effect. Except as set
forth in the Prospectus, all property held under lease by the Company and its subsidiaries is held
by them under valid, existing and enforceable leases, free and clear of all liens, encumbrances,
claims, security interests and defects, except such as would not have a Material Adverse Effect.
Subsequent to the respective dates as of which information is given in the Registration Statement
and the Prospectus, (i) there has not been any Material Adverse Effect; (ii) neither the Company
nor any of its subsidiaries has sustained any loss or interference with its assets, businesses or
properties (whether owned or leased) from fire, explosion, earthquake, flood or other calamity,
whether or not covered by insurance, or from any labor dispute or any court or legislative or other
governmental action, order or decree which would have a Material Adverse Effect; and (iii) since
the date of the latest balance sheet included or incorporated by reference in the Registration
Statement and the Prospectus, neither the Company nor its subsidiaries has (A) issued any
securities or incurred any liability or obligation, direct or contingent, for borrowed money,
except such liabilities or obligations incurred in the ordinary course of business, (B) entered
into any transaction not in the ordinary course of business or (C) declared or paid any dividend or
made any distribution on any shares of its stock or redeemed, purchased or otherwise acquired or
agreed to redeem, purchase or otherwise acquire any shares of its capital stock.

(j) There is no document, contract or other agreement required to be described in the
Registration Statement or Prospectus or to be filed as an exhibit to the Registration Statement
which is not described or filed as required by the Securities Act or Rules. Each description of a
contract, document or other agreement in the Registration Statement and the Prospectus accurately
reflects in all material respects the terms of the underlying contract, document or other
agreement. Each contract, document or other agreement described in the Registration Statement and
Prospectus or listed in the Exhibits to the Registration Statement or incorporated by reference is
in full force and effect and is valid and enforceable by and against the Company or its subsidiary,
as the case may be, in accordance with its terms. Neither the Company nor any of its subsidiaries,
if a subsidiary is a party, nor to the Company’s knowledge, any other party, is in default in the
observance or performance of any term or obligation to be performed by it under any such agreement,
and no event has occurred which with notice or lapse of time or both would constitute such a
default, in any such case which default or event, individually or in the aggregate, would have a
Material Adverse Effect. No default exists, and no event has occurred which with notice or lapse
of time or both would constitute a default, in the due performance and observance of any term,
covenant or condition, by the Company or its subsidiary, if a subsidiary is a party thereto, of any
other agreement or instrument to which the Company or any of its subsidiaries is a party or by
which Company or its properties or business or a subsidiary or its properties or business may be
bound or affected which default or event, individually or in the aggregate, would have a Material
Adverse Effect.

(k) Neither the Company nor any of its subsidiaries is in violation of any term or provision
of (i) its charter or by-laws or (ii) of any franchise, license, permit, judgment, decree, order,
statute, rule or regulation, except, with respect to subsection (ii), where the consequences of
such violation, individually or in the aggregate, would not have a Material Adverse Effect.

(l) This Agreement has been duly authorized, executed and delivered by the Company.

(m) Neither the execution, delivery and performance of this Agreement by the Company nor the
consummation of any of the transactions contemplated hereby (including, without limitation, the
issuance and sale by the Company of the Shares) will give rise to a right to terminate or
accelerate the due date of any payment due under, or conflict with or result in the breach of any
term or provision of, or constitute a default (or an event which with notice or lapse of time or
both would constitute a default) under, or require any consent or waiver under, or result in the
execution or imposition of any lien, charge or encumbrance upon any  properties or assets
of the Company or its subsidiaries pursuant to the terms of, any indenture, mortgage, deed of trust
or other agreement or instrument to which the Company or any of its subsidiaries is a party or by
which either the Company or its subsidiaries or any of their properties or businesses is bound, or
any franchise, license, permit, judgment, decree, order, statute, rule or regulation applicable to
the Company or any of its subsidiaries or violate any provision of the charter or by-laws of the
Company or any of its subsidiaries, except for such consents or waivers which have already been
obtained and are in full force and effect or that the failure to obtain would not, individually or
in the aggregate, have a Material Adverse Effect.

(n) The Company has authorized and outstanding capital stock as set forth under the caption
“Capitalization” in the Prospectus, and since such date there has been no change in the capital
stock of the Company except for issuances pursuant to employee benefit plans described in the
Prospectus or upon exercise of outstanding warrants described in the Prospectus. The certificates
evidencing shares of Common Stock are in due and proper legal form. All of the issued and
outstanding shares of Common Stock have been duly and validly issued and are fully paid and
nonassessable. There are no statutory preemptive or other similar rights to subscribe for or to
purchase or acquire any shares of Common Stock of the Company or any of its subsidiaries or any
such rights pursuant to its Articles of Incorporation or by-laws or any agreement or instrument to
or by which the Company or any of its subsidiaries is a party or bound. The Shares, when delivered
by the Company pursuant to this Agreement, will be duly and validly issued, fully paid and
nonassessable and none of them will be issued in violation of any preemptive or other similar
right. Except as disclosed in the Registration Statement and the Prospectus, there is no
outstanding option, warrant or other right calling for the issuance of, and there is no commitment,
plan or arrangement to issue, any share of stock of the Company or any of its subsidiaries or any
security convertible into, or exercisable or exchangeable for, such stock. The Common Stock and
the Shares conform in all material respects to all statements in relation thereto contained in the
Registration Statement and the Prospectus. All outstanding shares of capital stock of each of the
Company’s subsidiaries have been duly authorized and validly issued, and are fully paid and
nonassessable and are owned directly by the Company or by another wholly-owned subsidiary of the
Company free and clear of any security interests, liens, encumbrances, equities or claims, other
than those described in the Prospectus.

(o) Except as set forth in the Company’s Current Report on Form 8-K filed March 14, 2005, no
holder of any security of the Company has any right, which has not been waived, to have any
security owned by such holder included in the Registration Statement or to demand registration of
any security owned by such holder for a period of 90 days after the date of this Agreement. Each
director and executive officer of the Company and other Company shareholders listed on Schedule I
has delivered to the Placement Agents his enforceable written lock-up agreement in the form
attached to this Agreement as Exhibit B hereto (“Lock-Up Agreement”).

(p) All necessary corporate action has been duly and validly taken by the Company to authorize
the execution, delivery and performance of this Agreement and the issuance and sale of the Shares
by the Company. This Agreement has been duly and validly authorized, executed and delivered by the
Company and constitutes and will constitute legal, valid and binding obligations of the Company
enforceable against the Company in accordance with their respective terms, except as rights to
indemnity under Section 6 of the Agreement may be limited by applicable law and as the
enforceability thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or
other similar laws affecting the enforcement of creditors’ rights generally and by general
equitable principles.

(q) Neither the Company nor any of its subsidiaries is involved in any labor dispute or, to
the knowledge of the Company, is any such dispute threatened, which dispute would have a Material
Adverse Effect. The Company is not aware of any existing or imminent labor disturbance by the
employees of any of its principal suppliers or contractors which would have a Material Adverse
Effect. The Company is not aware of any threatened or pending litigation between the Company or its
subsidiaries and any of its executive officers or directors which, if adversely determined, could
have a Material Adverse Effect nor is the Company aware of any plan of any such officers or
directors to leave the employment of the Company.

(r) No transaction has occurred between or among the Company and any of its officers or
directors, shareholders or any affiliate or affiliates of any such officer or director or
shareholder that is required to be described in and is not described in the Registration Statement
and the Prospectus.

(s) The Company has not taken, nor will it take, directly or indirectly, any action designed
to or which might reasonably be expected to cause or result in, or which has constituted or which
might reasonably be expected to constitute, the stabilization or manipulation of the price of the
Common Stock or any security of the Company to facilitate the sale or resale of any of the Shares.

(t) The Company and each of its subsidiaries has filed all Federal, state, local and foreign
tax returns which are required to be filed through the date hereof, which returns are true and
correct in all material respects or has received timely extensions thereof, and has paid all taxes
shown on such returns and all assessments received by it to the extent that the same are material
and have become due. There are no tax audits or investigations pending, which if adversely
determined would have a Material Adverse Effect; nor are there any material proposed additional tax
assessments against the Company or any of its subsidiaries.

(u) The Shares have been duly authorized for quotation on the American Stock Exchange, subject
to official Notice of Issuance.

(v) The Company has taken no action designed to, or likely to have the effect of, terminating
the registration of the Common Stock under the Exchange Act or the quotation of the Common Stock on
the American Stock Exchange, nor has the Company received any notification that the Commission or
the American Stock Exchange is contemplating terminating such registration or quotation,
respectively.

(w) The books, records and accounts of the Company and its subsidiaries accurately and fairly
reflect, in reasonable detail, the transactions in, and dispositions of, the assets of, and the
results of operations of, the Company and its subsidiaries. The Company and each of its
subsidiaries maintains a system of internal accounting controls sufficient to provide reasonable
assurances that (i) transactions are executed in accordance with management’s general or specific
authorizations, (ii) transactions are recorded as necessary to permit preparation of financial
statements in accordance with generally accepted accounting principles and to maintain asset
accountability, (iii) access to assets is permitted only in accordance with management’s general or
specific authorization and (iv) the recorded accountability for assets is compared with the
existing assets at reasonable intervals and appropriate action is taken with respect to any
differences.

(x) The Company and its subsidiaries are insured by insurers of recognized financial
responsibility against such losses and risks and in such amounts as are customary in the businesses
in which they are engaged or propose to engage after giving effect to the transactions described in
the Prospectus; all policies of insurance and fidelity or surety bonds insuring the Company or any
of its subsidiaries or the Company’s or its subsidiaries’ respective businesses, assets, employees,
officers and directors are in full force and effect; the Company and each of its subsidiaries are
in compliance with the terms of such policies and instruments in all material respects; and neither
the Company nor any subsidiary of the Company has any reason to believe that it will not be able to
renew its existing insurance coverage as and when such coverage expires or to obtain similar
coverage from similar insurers as may be necessary to continue its business at a cost that is not
materially greater than the current cost. To the Company’s knowledge, neither the Company nor any
of its subsidiaries has been denied any insurance coverage which it has sought or for which it has
applied.

(y) Each approval, consent, order, authorization, designation, declaration or filing of, by or
with any regulatory, administrative or other governmental body necessary in connection with the
execution and delivery by the Company of this Agreement and the consummation of the transactions
herein contemplated required to be obtained or performed by the Company (except such additional
steps as may be necessary to qualify the Shares under the state securities or Blue Sky laws) has
been obtained or made and is in full force and effect.

(z) Other than JP Morgan, a greater than 5% shareholder of the Company, there are no known
affiliations with the National Association of Securities Dealers, Inc. (the “NASD”) among the
Company’s officers, directors or any five percent or greater shareholder of the Company, except as
set forth in the Registration Statement, otherwise disclosed in writing to the Placement Agents.

(aa) (i) Each of the Company and each of its subsidiaries is in compliance in all material
respects with all rules, laws and regulation relating to the use, treatment, storage and disposal
of toxic substances and protection of health or the environment (“Environmental Law”) which are
applicable to its business; (ii) neither the Company nor its subsidiaries has received any notice
from any governmental authority or third party of an asserted claim under Environmental Laws; (iii)
each of the Company and each of its subsidiaries has received all material permits, licenses or
other approvals required of it under applicable Environmental Laws to conduct its business and is
in compliance with all material terms and conditions of any such permit, license or approval; (iv)
to the Company’s knowledge, no facts currently exist that will require the Company or any of its
subsidiaries to make future material capital expenditures to comply with Environmental Laws; and
(v) no property which is or has been owned, leased or occupied by the Company or its subsidiaries
has been designated as a Superfund site pursuant to the Comprehensive Environmental Response,
Compensation of Liability Act of 1980, as amended (42 U.S.C. Section 9601, et. seq.) (“CERCLA”) or
otherwise designated as a contaminated site under applicable state or local law. Neither the
Company nor any of its subsidiaries has been named as a “potentially responsible party” under
CERCLA.

(bb) In the ordinary course of its business, the Company periodically reviews the effect of
Environmental Laws on the business, operations and properties of the Company and its subsidiaries,
in the course of which the Company identifies and evaluates associated costs and liabilities
(including, without limitation, any capital or operating expenditures required for clean up,
closure of properties or compliance with Environmental Laws, or any permit, license or approval,
any related constraints on operating activities and any potential liabilities to third parties).
On the basis of such review, the Company has reasonably concluded that such associated costs and
liabilities would not, singly or in the aggregate, have a Material Adverse Effect.

(cc) The Company is not and, after giving effect to the offering and sale of the Shares and
the application of proceeds thereof as described in the Prospectus, will not be an “investment
company” within the meaning of the Investment Company Act of 1940, as amended (the “Investment
Company Act”).

(dd) The Company or any other person associated with or acting on behalf of the Company
including, without limitation, any director, officer, agent or employee of the Company or its
subsidiaries, has not, directly or indirectly, while acting on behalf of the Company or its
subsidiaries (i) used any corporate funds for unlawful contributions, gifts, entertainment or other
unlawful expenses relating to political activity; (ii) made any unlawful payment to foreign or
domestic government officials or employees or to foreign or domestic political parties or campaigns
from corporate funds; (iii) violated any provision of the Foreign Corrupt Practices Act of 1977, as
amended; (iv) made any other unlawful payment; or (v) violated the Company’s code of ethics.

(ee) Except as described the Prospectus, the Company has not sold or issued any shares of
Common Stock during the six-month period preceding the date of the Prospectus, including any sales
pursuant to Rule 144A under, or Regulations D or S of, the Securities Act, other than shares issued
pursuant to employee benefit plans, qualified stock options plans or other employee compensation
plans or pursuant to outstanding options, rights or warrants.

(ff) The Company has fulfilled its obligations, if any, under the minimum funding standards of
Section 302 of the U.S. Employee Retirement Income Security Act of 1974 (“ERISA”) and the
regulations and published interpretations thereunder with respect to each “plan” as defined in
Section 3(3) of ERISA and such regulations and published interpretations in which its employees are
eligible to participate and each such plan is in compliance in all material respects with the
presently applicable provisions of ERISA and such regulations and published interpretations. No
“Reportable Event” (as defined in 12 ERISA) has occurred with respect to any “Pension Plan” (as
defined in ERISA) for which the Company could have any liability.

(gg) None of the Company or its directors and officers has distributed and will not distribute
prior to the later of (i) the Closing Date, and (ii) completion of the distribution of the Shares,
any offering material in connection with the offering and sale of the Shares other than any
preliminary prospectus and the Prospectus.

(hh) The statistical, scientific and market-related data included in the Prospectus are based
on or derived from sources which the Company believes to be reliable and accurate.

(ii) The Company has established and maintains disclosure controls and procedures (as such
term is defined in Rule 13a-15 under the Exchange Act), which (i) are designed to ensure that
material information relating to the Company is made known to the Company’s principal executive
officer and its principal financial officer by others within those entities, particularly during
the periods in which the periodic reports required under the Exchange Act are being prepared; (ii)
provide for the periodic evaluation of the effectiveness of such disclosure controls and procedures
as of the end of each of the Company’s quarterly and annual fiscal periods; and (iii), as of the
end of the periods covered by each periodic report filed under the Exchange Act and incorporated by
reference into the Prospectus, were effective in all material respects to perform the functions for
which they were established. Based on the evaluation of its disclosure controls and procedures,
the Company is not aware of (i) any significant deficiency in the design or operation of internal
controls which could adversely affect the Company’s ability to record, process, summarize and
report financial data or any material weaknesses in internal controls; or (ii) any fraud, whether
or not material, that involves management or other employees who have a significant role in the
Company’s internal controls. Since the date of the most recent evaluation of such disclosure
controls and procedures, there have been no changes that have materially affected, or are
reasonably likely to materially affect, the Company’s internal control over financial reporting,
including any corrective actions with regard to significant deficiencies and material weaknesses.

file such Prospectus pursuant to Rule 424(b) under the Securities Act not later than the
Commission’s close of business on the second business day following the execution and delivery of
this Agreement, or, if applicable, such earlier time as may be required by the Rules.

(ii) The Company shall promptly advise the Placement Agents in writing (A) when any
post-effective amendment to the Registration Statement shall have become effective or any
supplement to the Prospectus shall have been filed, (B) of any request by the Commission for any
amendment of the Registration Statement or the Prospectus or for any additional information, (C) of
the issuance by the Commission of any stop order suspending the effectiveness of the Registration

institution or threatening of any proceeding for that purpose and (D) of the receipt by the Company
of any notification with respect to the suspension of the qualification of the Shares for sale in
any jurisdiction or the initiation or threatening of any proceeding for such purpose. The Company
shall not file any amendment of the Registration Statement or supplement to the Prospectus or any
document incorporated by reference in the Registration Statement unless the Company has furnished
each Placement Agent a copy for its review prior to filing and shall not file any such proposed
amendment or supplement to which the Placement Agents reasonably object. The Company shall use its
best efforts to prevent the issuance of any such stop order and, if issued, to obtain as soon as
possible the withdrawal thereof.

(iii) If, at any time when a prospectus relating to the Shares is required to be delivered
under the Securities Act and the Rules, any event occurs as a result of which the Prospectus as
then amended or supplemented would include any untrue statement of a material fact or omit to state
any material fact necessary to make the statements therein in the light of the circumstances under
which they were made not misleading, or if it shall be necessary to amend or supplement the
Prospectus to comply with the Securities Act or the Rules, the Company promptly shall prepare and
file with the Commission, subject to the second sentence of paragraph (ii) of this Section 5(a), an
amendment or supplement which shall correct such statement or omission or an amendment which shall
effect such compliance.

Agents as soon as practicable an earnings statement which shall satisfy the provisions of Section
11(a) of the Securities Act or Rule 158 of the Rules.

(v) The Company shall furnish to the Placement Agents and counsel for the Placement Agent,
without charge, signed copies of the Registration Statement (including all exhibits thereto and
amendments thereof) and, so long as delivery of a prospectus by a Placement Agent or dealer may be
required by the Securities Act or the Rules, as many copies of any preliminary prospectus and the
Prospectus and any amendments thereof and supplements thereto as the Placement Agents may
reasonably request. If applicable, the copies of the Registration Statement and Prospectus and
each amendment and supplement thereto furnished to the Placement Agents will be identical to the
electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to
the extent permitted by Regulation S-T.

(vi) The Company shall cooperate with the Placement Agents and their counsel in endeavoring to
qualify the Shares for offer and sale in connection with the offering under the laws of such
jurisdictions as the Placement Agents may designate and shall maintain such qualifications in
effect so long as required for the distribution of the Shares; provided, however, that the Company
shall not be required in connection therewith, as a condition thereof, to qualify as a foreign
corporation or to execute a general consent to service of process in any jurisdiction or subject
itself to taxation as doing business in any jurisdiction.

(vii) The Company, during the period when the Prospectus is required to be delivered under the
Securities Act and the Rules or the Exchange Act, will file all reports and other documents
required to be filed with the Commission pursuant to Section 13, 14 or 15 of the Exchange Act
within the time periods required by the Exchange Act and the regulations promulgated thereunder.

(viii) Without the prior written consent of CIBC World Markets Corp., for a period of 60 days
after the date of this Agreement, the Company shall not issue, sell or register with the Commission
(other than on Form S-8 or on any successor form), or otherwise dispose of, directly or indirectly,
any equity securities of the Company (or any securities convertible into, exercisable for or
exchangeable for equity securities of the Company), except for: (i) the issuance of the Shares
pursuant to the Registration Statement; (ii) the issuance of shares pursuant to the Company’s
existing employee benefit plans or upon exercise of outstanding warrants as described in the
Registration Statement and the Prospectus; (iii) any corporate strategic development transaction;
provided that in each of cases (iii) none of these securities may be transferred within such 60-day
period and the Company shall enter stop transfer instructions with its transfer agent and registrar
with respect to any such securities; or (iv) the registration with the Commission of 2,000,000
shares of Class A common stock issued to IriSys, Inc. on March 8, 2005. In the event that during
this period any shares are issued to any person identified on Schedule I hereto, such shares shall
be subject to the Lock-Up Agreement executed by such person.

(ix) On or before completion of this offering, the Company shall make all filings required
under applicable securities laws and by the American Stock Exchange (including any required
registration under the Exchange Act).

(x) Prior to the Closing Date, the Company will issue no press release or other communications
directly or indirectly and hold no press conference with respect to the Company, the condition,
financial or otherwise, or the earnings, business affairs or business prospects of any of them, or
the offering of the Shares without the prior written consent of the Placement Agents unless in the
judgment of the Company and its counsel, and after notification to the Placement Agents, such press
release or communication is required by law.

(xi) The Company will apply the net proceeds from the offering of the Shares in the manner set
forth under “Use of Proceeds” in the Prospectus.

(b) The Company agrees to pay, or reimburse if paid by the Placement Agents, whether or not
the transactions contemplated hereby are consummated or this Agreement is terminated, all costs and
expenses incident to the performance of the obligations of the Company under this Agreement
including those relating to: (i) the preparation, printing, filing and distribution of the
Registration Statement including all exhibits thereto, any preliminary prospectus, the Prospectus,
all amendments and supplements to the Registration Statement and the Prospectus and any document
incorporated by reference therein, and the printing, filing and distribution of this Agreement;
(ii) the preparation and delivery of certificates for the Shares; (iii) the registration or
qualification of the Shares for offer and sale under the securities or Blue Sky laws of the various
jurisdictions referred to in Section 5(a)(vi), including the reasonable fees and disbursements of
counsel for the Placement Agents in connection with such registration and qualification and the
preparation, printing, distribution and shipment of preliminary and supplementary Blue Sky
memoranda; (iv) the furnishing (including costs of shipping and mailing) to the Placement Agents of
copies of any preliminary prospectus, the Prospectus and all amendments or supplements to the
Prospectus, and of the several documents required by this Section to be so furnished, as may be
reasonably requested for use in connection with the offering and sale of the Shares; (v) if
applicable, the filing fees of the NASD in connection with its review of the terms of the public
offering and reasonable fees and disbursements of counsel for the Placement Agents in connection
with such review; (vi) inclusion of the Shares for quotation on the American Stock Exchange; (vii)
the costs and expenses of the Company relating to investor presentations in connection with the
marketing of the offering of the Shares, including, without limitation, expenses associated with
the production of slides and graphics, fees and expenses of any consultants engaged by the Company
in connection with the presentations, travel and lodging expenses of the representatives and
officers of the Company and any such consultants, and the cost of any aircraft chartered by the
Company in connection with any investor presentations and (viii) all transfer taxes, if any, with
respect to the sale and delivery of the Shares by the Company. Subject to the provisions of
Section 8, the Placement Agents agree to pay, whether or not the transactions contemplated hereby
are consummated or this Agreement is terminated, all costs and expenses incident to the performance
of the obligations of the Placement Agents under this Agreement not payable by the Company pursuant
to the preceding sentence, including, without limitation, the fees and disbursements of counsel for
the Placement Agents.

6. Indemnification.

(a) The Company agrees to indemnify and hold harmless each Placement Agent and each person, if
any, who controls any Placement Agent within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act against any and all losses, claims, damages and liabilities, joint
or several (including any reasonable investigation, legal and other expenses incurred in connection
with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted),
to which they, or any of them, may become subject under the Securities Act, the Exchange Act or
other Federal or state law or regulation, at common law or otherwise, insofar as such losses,
claims, damages or liabilities arise out of or are based upon (i) any untrue statement or alleged
untrue statement of a material fact contained in any preliminary prospectus, the Registration
Statement or the Prospectus or any amendment thereof or supplement thereto, or in any Blue Sky
application or other information or other documents executed by the Company filed in any state or
other jurisdiction to qualify any or all of the Shares under the securities laws thereof (any such
application, document or information being hereinafter referred to as a “Blue Sky Application”) or
(ii) arise out of or are based upon any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein not misleading;
provided, however, that such indemnity shall not inure to the benefit of any Placement Agent (or
any person controlling such Placement Agent) on account of any losses, claims, damages or
liabilities arising from the sale of the Shares if such untrue statement or omission or alleged
untrue statement or omission was made in any preliminary prospectus, Registration Statement or the
Prospectus, or such amendment or supplement thereto, or in any Blue Sky Application in reliance
upon and in conformity with information furnished in writing to the Company by any Placement Agent
specifically for use therein. This indemnity agreement will be in addition to any liability which
the Company may otherwise have.

(b) Each Placement Agent agrees to indemnify and hold harmless the Company, and each person,
if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section
20 of the Exchange Act, each director of the Company, and each officer of the Company who signs the
Registration Statement, against any losses, claims, damages or liabilities to which such party may
become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon: (i) an untrue statement
or alleged untrue statement of a material fact contained in any preliminary prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement thereto; (ii) arise out of
or are based upon the omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading; or (iii) any failure on
the part of such Placement Agent to timely deliver the Prospectus to the Investors pursuant to the
requirements of the Securities Act (and the rules and regulations promulgated thereunder).
Notwithstanding the forgoing, the obligation of each Placement Agent to indemnify the Company
(including any controlling person, director or officer thereof) shall be limited:

(1) with respect to clauses (i) and (ii) of this Section 6(b), to the extent
that such untrue statement or alleged untrue statement or omission or alleged
omission was made in any preliminary prospectus, the Registration Statement or the
Prospectus or any such amendment or supplement in reliance upon and in conformity
with written information furnished to the Company by such Placement Agent expressly
for use therein;

(2) with respect to clause (iii) of this Section 6(b), to the extent that (A)
the Company shall sustain the burden of proving that any such losses, claims,
damages or liabilities resulted directly from the fact that such Placement Agent
arranged for the sale of Securities to a person to whom such Placement Agent failed
to send or give, at or prior to the Closing Date, a copy of the final Prospectus
Supplement, (B) the Company had previously furnished copies thereof (sufficiently in
advance of the Closing Date to allow for distribution by the Closing Date) to the
Placement Agent and such final Prospectus Supplement was required by law to be
delivered at or prior to the written confirmation of sale to such person, and (C)
such failure to give or send a final Prospectus Supplement by the Closing Date to
the party or parties asserting such loss, liability, claim, damage or expense would
have constituted the sole defense to the claim asserted by such person(s); and

(3) with respect to clauses (i), (ii) and (iii) of this Section 6(b), to the
amount of placement agent fees actually received by such Placement Agent pursuant to
this Agreement.

(c) Any party that proposes to assert the right to be indemnified under this Section will,
promptly after receipt of notice of commencement of any action, suit or proceeding against such
party in respect of which a claim is to be made against an indemnifying party or parties under this
Section, notify each such indemnifying party of the commencement of such action, suit or
proceeding, enclosing a copy of all papers served. No indemnification provided for in Section 6(a)
or 6(b) shall be available to any party who shall fail to give notice as provided in this Section
6(c) if the party to whom notice was not given was prejudiced by the failure to give such notice
but the omission so to notify such indemnifying party of any such action, suit or proceeding shall
not relieve it from any liability that it may have to any indemnified party for contribution or
otherwise than under this Section. In case any such action, suit or proceeding shall be brought
against any indemnified party and it shall notify the indemnifying party of the commencement
thereof, the indemnifying party shall be entitled to participate in, and, to the extent that it
shall wish, jointly with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the
indemnifying party to such indemnified party of its election so to assume the defense thereof and
the approval by the indemnified party of such counsel, the indemnifying party shall not be liable
to such indemnified party for any legal or other expenses, except as provided below and except for
the reasonable costs of investigation subsequently incurred by such indemnified party in connection
with the defense thereof. The indemnified party shall have the right to employ its counsel in any
such action, but the fees and expenses of such counsel shall be at the expense of such indemnified
party unless (i) the employment of counsel by such indemnified party has been authorized in writing
by the indemnifying parties, (ii) the indemnified party shall have been advised by counsel that
there may be one or more legal defenses available to it which are materially different from or in
addition to those available to the indemnifying party (in which case the indemnifying parties shall
not have the right to direct the defense of such action on behalf of the indemnified party) or
(iii) the indemnifying parties shall not have employed counsel to assume the defense of such action
within a reasonable time after notice of the commencement thereof, in each of which cases the
reasonable fees and expenses of counsel shall be at the expense of the indemnifying parties. An
indemnifying party shall not be liable for any settlement of any action, suit, and proceeding or
claim effected without its written consent, which consent shall not be unreasonably withheld or
delayed.

7. Contribution. In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in Section 6(a) or 6(b) is due in
accordance with its terms but for any reason is unavailable to or insufficient to hold harmless an
indemnified party in respect to any losses, liabilities, claims, damages or expenses referred to
therein, then each indemnifying party shall contribute to the aggregate losses, liabilities,
claims, damages and expenses (including any investigation, legal and other expenses reasonably
incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding
or any claims asserted, but after deducting any contribution received by any person entitled
hereunder to contribution from any person who may be liable for contribution) incurred by such
indemnified party, as incurred, in such proportion as is appropriate to reflect the relative
benefits received by the Company on the one hand and the Placement Agents on the other hand from
the offering of the Shares pursuant to this Agreement or, if such allocation is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the relative benefits
referred to above but also the relative fault of the Company on the one hand and the Placement
Agents on the other hand in connection with the actions, statements or omissions which resulted in
such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable
considerations. The Company and the Placement Agents agree that it would not be just and equitable
if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the
Placement Agents were treated as one entity for such purpose) or by any other method of allocation
which does not take account of the equitable considerations referred to above. The aggregate
amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and
referred to above shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or threatened, or any
claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged
omission. Notwithstanding the provisions of this Section 7, no Placement Agent shall be required
to contribute any amount in excess of the amount of placement agent fees actually received by such
Placement Agent pursuant to this Agreement. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section
7, each person, if any, who controls a Placement Agent within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such
Placement Agent, and each director of the Company, each officer of the Company who signed the
Registration Statement, and each person, if any, who controls the Company within the meaning of the
Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to
contribution as the Company. Any party entitled to contribution will, promptly after receipt of
notice of commencement of any action, suit or proceeding against such party in respect of which a
claim for contribution may be made against another party or parties under this Section 7, notify
such party or parties from whom contribution may be sought, but the omission so to notify such
party or parties from whom contribution may be sought shall not relieve the party or parties from
whom contribution may be sought from any other obligation it or they may have hereunder or
otherwise than under this Section 7. No party shall be liable for contribution with respect to any
action, suit, proceeding or claim settled without its written consent. The Placement Agents’
obligations to contribute pursuant to this Section 7 are several in proportion to their respective
amounts of placement agent fees each has actually received pursuant to this Agreement and not
joint.

8. Termination. 

(a) This Agreement may be terminated at any time prior to the Closing Date by the Placement
Agents by notifying the Company at any time at or before the Closing Date in the absolute
discretion of the Placement Agents if: (i) there has occurred any material adverse change in the
securities markets or any event, act or occurrence that has materially disrupted, or in the opinion
of the Placement Agents, will in the future materially disrupt, the securities markets or there
shall be such a material adverse change in general financial, political or economic conditions or
the effect of international conditions on the financial markets in the United States is such as to
make it, in the judgment of the Placement Agents, inadvisable or impracticable to market the Shares
or enforce contracts for the sale of the Shares; (ii) there has occurred any outbreak or material
escalation of hostilities or other calamity or crisis the effect of which on the financial markets
of the United States is such as to make it, in the judgment of the Placement Agents, inadvisable or
impracticable to market the Shares or enforce contracts for the sale of the Shares; (iii) trading
in the Shares or any securities of the Company has been suspended or materially limited by the
Commission or trading generally on the New York Stock Exchange, Inc., the American Stock Exchange,
Inc. or the Nasdaq National Market has been suspended or materially limited, or minimum or maximum
ranges for prices for securities shall have been fixed, or maximum ranges for prices for securities
have been required, by any of said exchanges or by such system or by order of the Commission, the
National Association of Securities Dealers, Inc., or any other governmental or regulatory
authority; (iv) a banking moratorium has been declared by any state or Federal authority; or (v) in
the judgment of the Placement Agents, there has been, since the time of execution of this Agreement
or since the respective dates as of which information is given in the Prospectus, any material
adverse change in the assets, properties, condition, financial or otherwise, or in the results of
operations, business affairs or business prospects of the Company and its subsidiaries considered
as a whole, whether or not arising in the ordinary course of business.

(b) If this Agreement is terminated pursuant to any of its provisions, the Company shall not
be under any liability to any Placement Agent, and no Placement Agent shall be under any liability
to the Company, except that if this Agreement is terminated by the Placement Agents because of any
failure, refusal or inability on the part of the Company to comply with the terms or to fulfill any
of the conditions of this Agreement, the Company will reimburse the Placement Agents for all
reasonable out-of-pocket expenses (including the reasonable fees and disbursements of their
counsel) incurred by them in connection with this Agreement and the proposed sale of the Shares or
in contemplation of performing their obligations hereunder.

9. [RESERVED]

10. Miscellaneous. The respective agreements, representations, warranties,
indemnities and other statements of the Company and the Placement Agents, as set forth in this
Agreement or made by or on behalf of them pursuant to this Agreement, shall remain in full force
and effect, regardless of any investigation (or any statement as to the results thereof) made by or
on behalf of any Placement Agent or the Company or any of their respective officers, directors or
controlling persons referred to in Sections 6 and 7 hereof, and shall survive delivery of and
payment for the Shares. In addition, the provisions of Sections 5(b), 6, 7 and 8 shall survive the
termination or cancellation of this Agreement.

This Agreement has been and is made for the benefit of the Placement Agents, the Company and
their respective successors and assigns, and, to the extent expressed herein, for the benefit of
persons controlling any of the Placement Agents, or the Company, and directors and officers of the
Company, and their respective successors and assigns, and no other person shall acquire or have any
right under or by virtue of this Agreement. The term “successors and assigns” shall not include
any Investor merely because of such purchase.

All notices and communications hereunder shall be in writing and mailed or delivered or by
telephone or telegraph if subsequently confirmed in writing, (a) if to the Placement Agents, c/o

original, with the same effect as if the signatures thereto and hereto were upon the same

Ladies and Gentlemen:

The undersigned entities set forth on Schedule I hereto (each an “Investor”), hereby confirm
and agree with you as follows:

1. This Purchase Agreement (the “Agreement”) is made as of April [8], 2005 between Avanir
Pharmaceuticals, a California corporation (the “Company”), and each Investor.

2. The Company has authorized the sale and issuance of up to 7,770,000 shares (the “Shares”)
of common stock of the Company, no par value (the “Common Stock”), subject to adjustment by the
Company’s Board of Directors, to certain investors (the “Offering”). The Offering has been
registered under the Securities Act of 1933, as amended, pursuant to the Company’s Registration
Statement on Form S-3 (No. 333-114389), as amended (the “Registration Statement”).

3. The Company and each Investor agree that each Investor will purchase from the Company and
the Company will issue and sell to each Investor the number of Shares, set forth opposite such
Investor’s name on Schedule I hereto, at a purchase price of $2.20 per share, pursuant to the Terms
and Conditions for Purchase of Shares attached hereto as Annex I and incorporated herein by
reference as if fully set forth herein. Each Investor acknowledges that the offering is not being
underwritten by the placement agents (the “Placement Agents”) named in the Prospectus (as
hereinafter defined) and that there is no minimum offering amount. Certificates representing the
Shares purchased by each Investor will not be issued to such Investor; instead, such Shares will be
credited to each Investor using customary book-entry procedures unless an Investor specifically
requests physical delivery of certificate(s) before the Closing, in which case, the Company shall
deliver physical stock certificate(s) and the Investor, concurrently with such delivery, shall
remit the purchase price to an account designated by the Company.

4. Except as disclosed to the Company in writing, each Investor represents that (a) it has had
no position, office or other material relationship within the past three years with the Company or
persons known to it to be affiliates of the Company, (b) it is not an NASD member or an Associated
Person (as such term is defined under the NASD Membership and Registration Rules Section 1011) as
of the Closing, and (c) neither the Investor or any group of Investors (as identified in a public
filing made with the Commission) of which the Investor is a part in connection with the offering of
the Shares acquired, or obtained the right to acquire, 20% or more of the Common Stock (or
securities convertible or exercisable for Common Stock) or the voting power of the Company on a
post-transaction basis.

5. Each Investor hereby confirms receipt of the Prospectus Supplement, dated April 5, 2005 and
the Base Prospectus, dated May 25, 2004 (collectively, the “Prospectus”) filed by the Company with
the Securities and Exchange Commission on April 6, 2005. Each Investor confirms that it had full
access to the Prospectus and the information incorporated by reference therein, and was fully able
to read and review such materials.

referred to as the “Agreements.”) The Company may accept or reject any one or more Agreements in
its sole discretion.

3. Delivery of the Shares at Closing. The completion of the purchase and sale of the

hereunder, as set forth opposite such Investor’s name on Schedule I hereto, to the Heller Ehrman
LLP (the “Escrow Agent”) client trust account.

The Company’s obligation to issue and sell the Shares to each Investor shall be subject to the
following conditions, any one or more of which may be waived by the Company: (a) receipt by the
Escrow Agent of a certified or official bank check or wire transfer of funds in the full amount of
the purchase price for the Shares being purchased; (b) completion of the purchases and sales of
Shares under the Agreements that may be executed with the Other Investors (provided that all

effectiveness of this Agreement); and (c) the accuracy of the representations and warranties made
by each Investor and the fulfillment of those undertakings of each Investor to be fulfilled prior
to the Closing.

Each Investor’s obligation to purchase the Shares shall be subject to the condition that the
Placement Agents shall not have (a) terminated the Placement Agency Agreement dated April 5, 2005,
between the Company and the Placement Agents (the “Placement Agency Agreement”) pursuant to the
terms thereof or (b) determined that the conditions to closing in the Placement Agency Agreement

4.2 This Agreement constitutes a valid and binding obligation of the Company enforceable
against the Company in accordance with its terms, except as enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’
and contracting parties’ rights generally and except as enforceability may be subject to general
principles of equity (regardless of whether such enforceability is considered in a proceeding in
equity or at law).

	 	5.	 	Representations, Warranties and Covenants of each
Investor.

5.1 Each Investor represents and warrants that it has received the Company’s Prospectus.

5.2 Each Investor, if outside the United States, will comply with all applicable laws and

such Investor has full right, power, authority and capacity to enter into this Agreement and to
consummate the transactions contemplated hereby and has taken all necessary action to authorize the
execution, delivery and performance of this Agreement, and (ii) this Agreement constitutes a valid
and binding obligation of such Investor enforceable against such Investor in accordance with its
terms, except as enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors’ and contracting parties’ rights
generally and except as enforceability may be subject to general principles of equity (regardless
of whether such enforceability is considered in a proceeding in equity or at law).

5.4 Each Investor understands that nothing in the Prospectus, this Agreement or any other
materials presented to such Investor in connection with the purchase and sale of the Shares
constitutes legal, tax or investment advice. Such Investor has consulted such legal, tax and
investment advisors as it, in its sole discretion, has deemed necessary or appropriate in
connection with its purchase of Shares.

5.5 From and after obtaining the knowledge of the sale of the Shares contemplated hereby,
such Investor has not taken, and prior to the public announcement of the transaction such Investor
shall not take, any action that has caused or will cause such Investor to have, directly or
indirectly, sold or agreed to sell any shares of Common Stock, effected any short sale, whether or
not against the box, established any “put equivalent position” (as defined in Rule 16a-1(h) under
the Securities Exchange Act of 1934, as amended) with respect to the Common Stock, granted any
other right (including, without limitation, any put or call option) with respect to the Common
Stock or with respect to any security that includes, relates to or derived any significant part of
its value from the Common Stock, whether or not, directly or indirectly, in order to hedge its
position in the Shares.

6.1 The Company and each Investor hereby appoint Heller Ehrman LLP as the “Escrow Agent”
under this Agreement to serve from the date hereof until the Closing; provided, however, that no

provisions of this Agreement, including without limitation all such actions, decisions and powers
as are reasonably incidental thereto. The Escrow Agent may execute any of its duties hereunder by
or through agents, designees or employees.

(b) Neither the Escrow Agent nor any of its partners, directors, members, officers, agents,
designees or employees (collectively, “Escrow Agent Indemnified Persons”) shall be liable or
responsible to any Investor, the Company or any third party for any action taken or omitted to be
taken by the Escrow Agent or any other such Escrow Agent Indemnified Persons in accordance with
this Agreement or under any related agreement, instrument or document.

7. Survival of Representations, Warranties and Agreements. Notwithstanding any
investigation made by any party to this Agreement, all covenants, agreements, representations and

outside the United States for the issuance and sale of the Shares and compliance by the Company
with the provisions of the Agreement.

In connection with our opinion in Paragraph 5 of Part III below (and elsewhere) relating to
any Material Agreement, we have not reviewed, and express no opinion on (i) financial covenants or
similar provisions requiring financial calculations or determinations to ascertain compliance; (ii)
provisions relating to the occurrence of a “material adverse event” or words of similar import; or
(iii) parol evidence bearing on interpretation or construction. To the extent that any Material
Agreement is governed by the laws of any jurisdiction other than the laws of the State of
California or the State of New York, our opinion relating to those agreements is based solely upon
the plain meaning of their language without regard to interpretation or construction that might be
indicated by the laws governing those agreements or instruments.

As to matters of fact material to our opinion, we have relied upon the representations of
factual matters contained in the Backup Certificate.

In connection with our opinion in Paragraph 10 of Part III below, we have assumed that,
pending the uses identified in the Prospectus, the net proceeds of the offering contemplated by the
Prospectus will be invested in government securities within the meaning of the Investment Company
Act of 1940, as amended (the “Investment Company Act”), to the extent necessary to ensure that the
Company will not hold “investment securities” (within the meaning of the Investment Company Act)
having a value exceeding 40% of the Company’s total assets (exclusive of government securities and
cash items) on an unconsolidated basis. We have also not considered the effect on such opinion of
the identity, business or control of any of the Company’s shareholders and have assumed that none
of the Company’s shareholders would be deemed an “investment company” within the meaning of the
Investment Company Act.

As used in our opinion, the expressions “to our knowledge,” “known to us,” and similar phrases
mean that, after an examination of the documents made available to us by the Company and after
inquiries of officers of the Company, but without any further independent factual investigation, we
find no reason to believe that the statements herein so qualified are inaccurate. Further, the
expressions “to our knowledge,” “known to us,” and similar phrases refer to the actual knowledge of
attorneys in this firm who are or have been involved in substantive legal representation of the
Company regarding the Agreement and the transactions contemplated thereby. Except to the extent
expressly set forth herein, we have not undertaken any independent investigation to determine the
existence or absence of any fact or the accuracy of any statement so qualified, and any limited
inquiry undertaken by us during the preparation of this opinion letter should not be regarded as
such investigation. Except to the extent expressly set forth herein, no inference as to our
knowledge of any matters bearing on the accuracy of any statement so qualified should be drawn from
our representation of the Company or our rendering of the opinions set forth below.

We have also assumed that there are no facts or circumstances relating to the Placement Agents
or any holder of securities that might prevent them from enforcing any of the rights to which our
opinion relates (for example, lack of due incorporation by the Placement Agents, regulatory
prohibitions relating to the Placement Agents or failure on the part of the Placement Agents to
qualify to do business in any state where such qualification is a prerequisite to enforcement of
rights under the Agreement).

II.

With respect to the opinions set forth in Part III below, we express no opinion as to:

a. The anti-fraud laws, rule or regulations of any jurisdiction.

b. The tax, anti-trust, land use, export, safety, environmental

c. Except as set forth in paragraph 9 below, the securities laws of any jurisdiction.

d. The applicable choice-of-law rules that may affect the interpretation of the Agreement.

e. The financial statements and schedules and other financial and statistical data included in
the Registration Statement or Prospectus.

f. Any state or federal laws, rules or regulations applicable to the transactions contemplated
by the Agreement because of the nature of the business of any party thereto other than the Company.

g. The past, present or future fair market value of any securities.

This opinion is limited to the federal laws of the United States of America and the laws of
the State of California and the State of New York. We disclaim any opinion as to the laws of any
other jurisdiction and we further disclaim any opinion as to any statute, rule, regulation,
ordinance, order or other promulgation of any regional or local governmental body. Without
limiting the generality of the foregoing, we are not acting here as experts on, and we do not
express any opinion on any applicable laws, rules or regulations relating to patents, copyrights,
trademarks and other proprietary rights and licenses.

III.

Based upon the foregoing and our examination of such questions of law as we have deemed
necessary or appropriate for the purpose of this opinion, and subject to the assumptions,
exceptions, limitations and qualifications expressed in this opinion letter, it is our opinion
that:

1. The Company, Xenerex and AHC have been duly incorporated and are validly existing as
corporations in good standing under the laws of the State of California, and the Company has all
corporate power and authority necessary to own or hold its properties and to conduct its business
as described in the Registration Statement, except where the failure to have such power or
authority would not have, singularly or in the aggregate, a material adverse effect on the
condition (financial or otherwise), results of operations, business or prospects of the Company and
its subsidiaries taken as a whole.

2. The Company has an authorized capitalization as set forth in the Prospectus, and all of the
issued shares of Class A Common Stock of the Company have been duly authorized and validly issued,
and are non-assessable and fully-paid. Such shares conform to the description thereof contained
under the heading “Description of Securities” in the Prospectus. The Shares being delivered by the
Company on the date of this opinion have been duly authorized and, when issued and delivered to and
paid for on the terms set forth in the Prospectus, will be validly issued, fully-paid and
non-assessable and conform to the description thereof contained under the heading “Description of
Securities” in the Prospectus.

3. There are no preemptive or other rights to subscribe for or to purchase from the Company
any of the Shares pursuant to the Company’s Amended and Restated Articles of Incorporation or
Bylaws nor, to our knowledge, are there any contractual preemptive rights to subscribe for any
Shares.

4. The Agreement has been duly authorized, executed and delivered by the Company.

5. The execution and delivery of the Agreement by the Company and the sale of the Shares as
contemplated by the Prospectus will not (A) to our knowledge, breach any of the terms or provisions
of, or constitute a default under, any Material Agreement, (B) result in any violation of the
Amended and Restated Articles of Incorporation or Bylaws of the Company, or (C) result in any
violation of any federal, California, or New York law, rule or regulation or, to our knowledge,
any decree, judgment or order applicable to the Company.

6. Except for the registration of the Shares under the Securities Act of 1933 (the “Securities
Act”) and such consents, approvals, authorizations, registrations or qualifications as may be
required under the Securities Exchange Act of 1934 and applicable state securities or blue sky laws
in connection with the sale of Shares by the Company, no consent, approval, authorization or order
of, or filing or registration with, any federal, California, or New York governmental or
regulatory agency or body is required in connection with the execution and delivery of the
Agreement by the Company and the sale of the Shares to the Buyers as contemplated by the
Prospectus.

7. The statements in the Prospectus under the heading “Description of Securities,” and in Item
15 of Part II of the Registration Statement, to the extent that they constitute summaries of law or
documents referred to therein, fairly summarize the law and documents described therein in all
material respects.

8. To our knowledge, there are no legal or governmental proceedings threatened or pending to
which the Company or any of its subsidiaries is a party or of which any property or asset of the
Company or any of its subsidiaries is the subject that are required to be described in the
Prospectus but are not so described.

9. The Registration Statement and the Prospectus, and any further amendments or supplements
thereto made by the Company prior to the date of this opinion letter, and all documents
incorporated by reference in the Registration Statement (other than the financial statements and
schedules and other financial and statistical data contained therein or incorporated by reference
therein, as to which with your permission we express no opinion) complied as to form in all
material respects with the requirements of the Securities Act.

10. The Company is not, and after giving effect to the offering and sale of the Shares and the
application of the proceeds thereof as described in the Prospectus will not be, required to
register as an “investment company” as such term is defined in the Investment Company Act.

IV.

In connection with the registration of the Shares, we have reviewed the Registration
Statement, the Prospectus and the 1934 Act Filings, but have not independently verified the
accuracy, completeness or fairness of the statements in those documents. Since we have undertaken
no independent investigation whatsoever, the limitations inherent in our review and therefore the
knowledge available to us are such that we are unable to assume any responsibility for such
accuracy, completeness or fairness. However, based on our limited review, no facts have come to
our attention that cause us to believe that the Registration Statement (including any document
incorporated by reference therein as of the date such document was filed with the Commission), as
of the date of the Company’s most recent Form 10-K, contained an untrue statement of a material
fact or omitted to state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made, not misleading, or
that the Registration Statement as of the date such document was filed with the Commission
(including any document incorporated by reference therein as of the date such document was filed
with the Commission), the Prospectus, or any further supplement to the Prospectus, in each case, as
of the date such document was filed with the Commission and at all times up to the date of this
opinion letter, contained an untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading (it being understood that we express no
belief with respect to the financial statements and schedules and other financial and statistical
data contained or incorporated by reference in the Registration Statement or Prospectus).

This opinion letter is rendered to you in connection with the issuance and sale of the Shares
as contemplated by the Agreement and is solely for your benefit in connection with the Agreement.
This opinion letter may not be relied upon by you for any other purpose, or relied upon by any
other person, firm, corporation or other entity for any purpose, without our prior written consent.
We disclaim any obligation to advise you of any facts, circumstances, events or developments in
areas covered by this opinion letter that occur or that are brought to our attention after the date
of this opinion letter.

Very truly yours,

OPINION OF SPECIAL REGULATORY COUNSEL FOR THE COMPANY

April [8], 2005

CIBC World Markets Corp.

Leerink Swann & Co.

As Placement Agents

c/o CIBC World Markets Corp.

300 Madison Avenue

New York, New York 10017

Ladies and Gentlemen:

We have been engaged by Avanir Pharmaceuticals, Inc., a California corporation (“the
Company”), to review, in connection with the issuance and sale of up to 7,770,000 shares of the
Company’s Class A Common Stock, the description in the offering materials of certain matters
pertaining to the approval and regulation of products by the United States Food and Drug
Administration. This opinion is being rendered pursuant to Section 4(f) of the Placement Agency
Agreement, dated as of April 5, 2005, between you and the Company. Subject to certain exceptions
set forth in the opinion, it is our opinion that, as of the date hereof:

(i) We are familiar with the United States Federal Food, Drug and Cosmetic Act (the “FDC Act”)
and related governmental regulatory matters as applied generally to drugs of the nature under
development by the Company and we have reviewed the sections of the Registration Statement and
Prospectus, including documents incorporated by reference therein, related to governmental
regulatory matters as applied generally to drugs of the nature under development by the Company
(collectively, the “Regulatory Disclosure”);

(ii) Insofar as the statements in the Regulatory Disclosure constitute summaries of legal
matters, documents or legal or regulatory proceedings referred to therein, the Regulatory
Disclosure accurately summarizes the information called for with respect to such legal matters,
documents or proceedings and accurately summarizes the matters referred to therein;

(iii) To our knowledge, there are no legal or governmental proceedings relating to the FDC
Act, the Public Health Service Act or any regulations of the FDA pending or threatened to which the
Company or any of its subsidiaries is a party, nor are we aware of any material violations of such
acts or regulations by the Company or any of its subsidiaries; and

(iv) As to the Regulatory Disclosure contained in each Registration Statement and Prospectus,
we have not independently verified its accuracy, completeness or fairness. Since we have
undertaken no independent investigation whatsoever, the limitations inherent in our review and
therefore the knowledge available to us are such that we are unable to assume any responsibility
for such accuracy, completeness or fairness. However, based on our limited review, no facts have
come to our attention that cause us to believe that the Regulatory Disclosure, as of the effective
date of the Registration Statement and at all times up to the date of this opinion letter,
contained any untrue statement of a material fact or omitted to state any material fact required to
be stated therein or necessary to make the statements therein not misleading, or that such sections
of the Prospectus or any amendment or supplement thereto, in each case, as of the date such
document was filed with the Commission and at all times up to the date of this opinion letter,
contained any untrue statement of a material fact or omitted to state any material fact necessary
in order to make the statements therein, in the light of the circumstances under which they were
made, not misleading.

This opinion is rendered to you in connection with the Underwriting Agreement and is solely
for your benefit. This opinion may not be relied upon by you for any other purpose, or relied upon
by any other person, firm, corporation, or other entity for any purpose, without our prior written
consent. We disclaim any obligation to advise you of any developments in areas covered by this
opinion that occur after the date of this opinion.

Very Truly Yours,

MATTERS TO BE COVERED IN THE OPINION OF

PATENT COUNSEL FOR THE COMPANY 

1. We have reviewed the statements under the captions “Risk Factors — [Intellectual Property
Risk Factor]” and “Business — [Intellectual Property].” To the best of our knowledge, and to the
extent that they constitute matters of law, summaries of legal matters, documents or proceedings,
or legal conclusions, the statements in the aforementioned portions of the Prospectus relating to
the Patents are correct in all material respects and fairly and correctly present the information
called for with respect thereto. Nothing has come to our attention which caused us to believe that
the above-mentioned sections of the Registration Statement and any amendment or supplement thereto
made available and reviewed by us, at the time the Registration Statement became effective and at
all times subsequent thereto up to and on the Closing Date, contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were made.

2. The Company is listed in the records of the United States Patent and Trademark Office
(“USPTO”) as the sole holder of record of the U.S. Company Patents. To the best of our knowledge,
there exist no asserted claims of third parties to any ownership interest or lien with respect to
the Company Patents, with the exception of a lien held by Drug Royalty USA, Inc. (“DRC”) in
connection with certain Company Patents listed in Schedule A of the Security Agreement between
Company and DRC (Annex A). With the exception of the DRC lien, we are not aware of any facts that
would preclude the Company from having clear title to the Company Patents listed in the Schedule.
To the best of our knowledge and based on facts certified by officers of the Company, the Company
owns as its sole property the Company Patents.

3. We are not aware of any material defect in the preparation or filing of the Patents that we
prosecuted on behalf of the Company.

4. To the extent that we have had or now have actual knowledge of any material prior art and
that we have appreciated or now appreciate the materiality of such prior art, we have complied with
and are complying with the required duty of candor and good faith in dealing with the U.S. Patent
and Trademark Office (“USPTO”), including the duty to disclose as defined in 37 CFR § 1.56 with
respect to all U.S. Patents in the Schedule which we prosecute or have prosecuted.

5. To the best of our knowledge, the Patents in the Schedule are being pursued by the Company
and have not lapsed, expired, or been abandoned by the Company.

6. To the best of our knowledge, there is no threatened action, suit, proceeding or claim by
others that the Company is infringing any patent.

7. To the best of our knowledge, there are no actions, suits, proceedings, or claims of third
parties to any ownership or inventorship interest with respect to any of the Patents, and we know
of no reasonable basis for any such actions, suits, proceedings, or claims.

8. Although we have not completed market clearance searches or analyses, we are not aware that
the Company in its current or proposed business is infringing any valid or enforceable patent
rights of others.

9. To the best of our knowledge, there are no legal or governmental proceedings pending
against the Company or its officers, the Company’s licensors or their officers, relating to any
patent application listed in the Schedule, other than review by patent offices of pending
applications for patents.

10. To the best of our knowledge and based on facts certified by officers of the Company,
there is no action, suit, claim or proceeding relating to patent rights or licenses, trademarks or
trademark rights, copyrights, collaborative research, licenses or royalty arrangements or
agreements or trade secrets, know-how or proprietary techniques, including processes and
substances, owned by or affecting the business or operations of the Company, which have been
asserted against the Company or any of its officers or directors.

11. To the best of our knowledge, there is no reason why the Patents if issued are not valid,
and if not yet issued, would not be valid or would not afford the Company patent protection for
Abreva, Neurodex and IgE.

12. To the best of our knowledge and based on facts certified by officers of the Company, we
are not aware of any parties that are infringing any Licensed Patent or Company Patent.

13. To the best of our knowledge and based on facts certified by officers of the Company, we
are not aware of anything that would affect the Company’s obligations under any of its agreements
relating to the Patents.

ACCOUNTANTS’ COMFORT LETTER

CIBC World Markets Corp.

Leerink Swann & Co.

As Placement Agents

c/o CIBC World Markets Corp.

300 Madison Avenue

New York, New York 10017

Ladies and Gentlemen:

We have audited the consolidated balance sheets of Avanir Pharmaceuticals and subsidiary (the
“Company”) as of September 30, 2004 and 2003, and the related consolidated statements of operations
and comprehensive operations, stockholders’ equity, and cash flows for each of the three years in
the period ended September 30, 2004, all included in the Company’s annual report on Form 10-K for
the year ended September 30, 2004, which is incorporated by reference in the registration statement
(No. 333-114389) on Form S-3 filed by the Company under the Securities Act of 1933 (the “1933
Act”); our report with respect thereto is also incorporated by reference in the registration
statement. The registration statement, including the related prospectus supplement dated April 5,
2005 is herein referred to as the registration statement.

In connection with the registration statement:

1. We are independent certified public accountants with respect to the Company within the
meaning of the Act and the applicable rules and regulations thereunder adopted by the Securities
and Exchange Commission (“SEC”) and the Public Company Accounting Oversight Board (US) (“PCAOB”).

2. In our opinion, the consolidated financial statements audited by us and incorporated by
reference in the registration statement comply as to form in all material respects with the
applicable accounting requirements of the 1933 Act and the Securities Exchange Act of 1934 (the
“1934 Act”), and the related rules and regulations adopted by the SEC.

3. We have not audited any financial statements of the Company as of any date or for any
period subsequent to September 30, 2004; although we have conducted an audit for the year ended
September 30, 2004, the purpose (and therefore the scope) of the audit was to enable us to express
our opinion on the consolidated financial statements as of September 30, 2004, and for the year
then ended, but not on the consolidated financial statements for any interim period within that
year. Therefore, we are unable to and do not express any opinion on the unaudited consolidated
balance sheets as of December 31, 2004 and the unaudited consolidated statements of operations and
comprehensive operations and of cash flows for the three months ended December 31, 2004 and 2003 ,
included in the Company’s quarterly report on Form 10-Q for the quarter ended December 31, 2004 ,
incorporated by reference in the registration statement, or on the financial position, results of
operations, or cash flows as of any date or for any period subsequent to September 30, 2004.

4. For purposes of this letter, we have read the minutes of the meetings of the stockholders
and the board of directors, including committees thereof, of the Company held since September 30,
2004 as set forth in the minutes book at [one/two days prior to close], 2005, officials of the
Company having advised us that the minutes of all such meetings through that date were set forth
therein; we have carried out other procedures to [one/two days prior to close], 2005 (our
procedures did not extend to [ ], 2005) as follows:

(a) With respect to the three month periods ended December 31, 2004 and 2003, we have—

(i) Performed the procedures specified by the American Institute of Certified Public
Accountants for a review of interim financial information as described in SAS No. 100, Interim
Financial Information, on the unaudited consolidated financial statements for these periods,
described in 3, included in the Company’s quarterly report on Form 10-Q for the quarters ended
December 31, 2003 and March 31, 2004, incorporated by reference in the registration statement.

(ii) Inquired of certain officials of the Company who have responsibility for financial and
accounting matters whether the unaudited consolidated financial statements referred to in a(i)
comply as to form in all material respects with the applicable accounting requirements of the 1934
Act as it applies to Form 10-Q, and the related rules and regulations adopted by the SEC.

(b) With respect to the period from January 1, 2005 to February 28, 2005, we have—

(i) Read the unaudited consolidated financial statements of the Company for January, February
of both 2005 and 2004 furnished us by the Company, officials of the Company having advised us that
no such financial statements as of any date or for any period subsequent to February 28, 2005, were
available.

(ii) Inquired of certain officials of the Company who have responsibility for financial and
accounting matters whether the unaudited consolidated financial statements referred to in b(i) are
stated on a basis substantially consistent with that of the audited consolidated financial
statements incorporated by reference in the registration statement.

The foregoing procedures do not constitute an audit conducted in accordance with PCAOB auditing
standards. Also, they would not necessarily reveal matters of significance with respect to the
comments in the following paragraph. Accordingly, we make no representations about the sufficiency
of the foregoing procedures for your purposes.

5. Nothing came to our attention as a result of the foregoing procedures, however, that caused
us to believe that:

(a) (i) Any material modifications should be made to the unaudited consolidated financial
statements described in 3, incorporated by reference in the registration statement, for them to be
in conformity with accounting principles generally accepted in the United States of America.

(ii) The unaudited consolidated financial statements described in 4(a)(i) do not comply as to
form in all material respects with the applicable accounting requirements of the 1934 Act as it
applies to Form 10-Q, and the related rules and regulations adopted by the SEC.

(b) (i) At February 28, 2005, there was any change in

the capital stock, increase in long-term debt, or decrease in net current assets or shareholders’
equity of the Company as compared with amounts shown in the December 31, 2004 unaudited condensed
consolidated balance sheet incorporated by reference in the registration statement, except that the
unaudited consolidated balance sheet as of February 28, 2005, which we were furnished by the
Company, showed an increase in capital stock of $104,867, a decrease in net current assets of
$4,035,754, and a decrease in shareholders’ equity of $4,907,734.

(ii) For the period from January 1, 2005 to February 28, 2005, there was a decrease, as
compared with the corresponding period in the preceding year, in the Company’s operating revenues,
or an increase in net loss attributable to common shareholders or net loss per share, except for a
decrease in operating revenues of $50,115 and an increase in net loss attributable to common
shareholders of $454,424.

6. As mentioned in 4(b)(i), Company officials have advised us that no consolidated financial
statements as of any date or for any period subsequent to February 28, 2005 are available;
accordingly, the procedures carried out by us with respect to changes in financial statement items
after February 28, 2005, have, of necessity, been even more limited than those with respect to the
periods referred to in 4. We have inquired of certain officials of the Company who have
responsibility for financial and accounting matters whether (a) at [one/two days prior to close],
2005 there was any change in the capital stock, increase in long-term debt or equity or any
decrease in consolidated net current assets shareholder’s equity of the Company as compared with
amounts shown on the December 31, 2004 unaudited consolidated balance sheet incorporated by
reference in the registration statement, or (b) for the period from February 28, 2005 to [one/two
days prior to close], 2005 there were any decreases, as compared with the corresponding period in
the preceding year, in operating revenues or increases in net loss attributable to common
shareholders or net loss per share. On the basis of these inquiries and our reading of the minutes
as described in 4, nothing came to our attention that caused us to believe that there was any such
change, increase, or decrease, except for changes comparable to those noted in 5(b).

7. For purposes of this letter, we have also read the items identified by you on the attached
copies of the Company’s registration statement on Form S-3, report on Form 10-K for the year ended
September 30, 2004 and related Form 14A Definitive Proxy, Form 10-Q and related earnings releases
on Form 8-K for the quarter ended December 31, 2004, and any financial information contained in the
prospectus supplement dated April 5, 2005, and have performed the following procedures, which were
applied as indicated with respect to the symbols explained below:

A. Compared the amount with (or recomputed from) the Company’s audited consolidated financial
statements (after rounding, where applicable) and notes thereto, as of or for the period indicated,
incorporated by reference in the registration statement and found them to be in agreement.

B. Compared the amount with (or recomputed from) the Company’s audited consolidated financial
statements (after rounding, where applicable) and notes thereto, as of or for the period indicated,
which are not included or incorporated by reference in the registration statement, and found them
to be in agreement.

C. Compared the amount with (or recomputed from) the Company’s unaudited consolidated
financial statements (after rounding, where applicable) and notes thereto, which are incorporated
by reference in the registration statement, and found them to be in agreement.

D. Compared the amount with (or recomputed from) a schedule or report prepared by the Company,
which was derived from the accounting records of the Company that are subject to the Company’s
internal controls and found them to be in agreement.

8. Our audit of the consolidated financial statements for the periods referred to in the
introductory paragraph of this letter was comprised of audit tests and procedures deemed necessary
for the purpose of expressing an opinion on such financial statements taken as a whole. For none
of the periods referred to therein, or any other period, did we perform audit tests for the purpose
of expressing an opinion on individual balances of accounts or summaries of selected transactions
such as those enumerated above, and, accordingly, we express no opinion thereon.

9. It should be understood that we make no representations regarding questions of legal
interpretation or regarding the sufficiency for your purposes of the procedures enumerated in 7;
also, such procedures would not necessarily reveal any material misstatement of the amounts or
percentages referred to above. Further, we have addressed ourselves solely to the foregoing data
as set forth in the registration statement and make no representations regarding the adequacy of
disclosure or regarding whether any material facts have been omitted.

Terms

For good and valuable consideration, the adequacy and receipt of which are hereby
acknowledged, FSII, the Company and the Executive, intending to be legally bound, agree as follows:

	 	 	 
	PART 1

Section 1.

	 	DUTIES AND SCOPE, COMPENSATION AND BENEFITS DURING

EMPLOYMENT

Term of Agreement; Termination of Employment
	 

	 	 

	 	(a)	 	Unless sooner terminated as provided in this Agreement, the term of this Agreement will begin
on the Effective Date and will end on the third anniversary of the Effective Date (the
“Initial Term”). Upon the first and each subsequent anniversary of the Effective Date, the
term of this Agreement will be automatically extended so as to end three years after the date
of such anniversary (each such three-year period, a “Renewal Term”) unless, prior to such
anniversary, either the Company or the Executive gives the other written notice of
non-renewal. The Initial Term and any Renewal Terms are collectively referred to as the
“Term”.

	 	(b)	 	Subject to the other terms of this Agreement, including those in Part 2, either the Company
or the Executive may terminate the Executive’s employment with the Company at any time and for
any reason or no reason upon written notice to the other party, with effect as of the
subsequent date specified in such notice.

Section 2.  Duties and Scope of Employment

	 	(a)	 	Position. As of the date of the 2005 annual stockholders’ meeting (the
“Stockholders’ Meeting Date”) of FSII, each of FSII and the Company will employ the Executive
in the position of President and Chief Executive Officer, reporting to the board of directors
of FSII and the Company, respectively. As of the Stockholders’ Meeting Date, the Executive
will be appointed as a member of the board of directors of FSII (the “Board”) and the board of
directors of the Company, which will be comprised of the same members as the Board. Until the
Stockholders’ Meeting Date, the Executive shall continue to be employed in the positions and
have the responsibilities he held immediately prior to the Effective Date.

	 	(b)	 	Obligations. The Executive shall have such duties, responsibilities and authority as
customarily held or exercised by a President and CEO of a public corporation, including but
not limited to general supervision over all of the business, operations and other affairs of
FSII and the Company and sole supervisory authority over all of the executive officers of FSII
the Company, subject to the oversight of the Board. During the Term, the Executive shall
devote the Executive’s full business efforts and time to the business and affairs of the
Company as needed to carry out his duties and responsibilities hereunder. The foregoing shall
not preclude the Executive from engaging in appropriate civic, charitable, religious or other
non-profit activities or from devoting a reasonable amount of time to private investments or
from serving on the boards of directors of other entities, provided that those activities do
not interfere or conflict with the Executive’s duties or responsibilities to the Company.

Section 3.  Base Compensation

While employed hereunder, the Company shall pay the Executive, as compensation for services, a base
salary of at least $630,000 per year. Salary increases will be considered after the first
anniversary of the Effective Date, or sooner in the discretion of the Board or its compensation
committee, so as to be competitive with compensation paid to similarly situated CEOs and on a basis
consistent with Company policies.

Section 4.  Other Compensation

	 	(a)	 	EFIP. While employed hereunder, the Executive will be enrolled in the Enhanced Fairchild
Incentive Plan (EFIP), at a participation level of at least 150%. By way of example only, if
an EFIP bonus is paid at the 100% target level, the Executive would receive a bonus equal to
150% of his qualified earnings under EFIP during the measurement period. Notwithstanding the
foregoing, the Executive shall remain entitled to any bonus commitment contained in his
employment agreement dated December 1, 2004.

(b) Equity Awards.

	 	(A)	 	Promotion Grants. The Executive shall receive a grant
of 45,000 FSII deferred stock units (“DSUs”), a grant of 46,000 FSII
performance shares (“Performance Shares”) and a grant of options to purchase
275,000 shares of FSII common stock (“Options”), subject to the following terms
(collectively, the “Promotion Grants”). The Promotion Grants will be made
under the Fairchild Semiconductor Stock Plan as such plan may be amended from
time to time (the “Plan”) and standard executive forms of agreements (the
“Equity Award Agreements”) as in effect on the date of the Promotion Grants,
the terms of which shall be consistent with the terms hereof. The Promotion
Grants are subject to FSII stockholder approval of certain amendments to the
Plan at FSII’s 2005 annual stockholders’ meeting. If such approval is not
obtained the Company and the Executive shall renegotiate the terms of this
Agreement in good faith so as to provide a similar measure of total
compensation as contemplated herein. The grant date or dates for the Promotion
Grants will be the same date or dates as the date or dates of annual stock
option (in the case of the DSUs and Options) and performance share (in the case
of the Performance Shares) grants to other executive officers and key employees
under the Plan, and in any case will not be later than July 15, 2005. The DSUs
will vest in one-third increments on each of the first three anniversaries of
the grant date, if in each case the Executive remains employed by the Company
under this Agreement on such anniversary, and vested DSUs must be settled by
delivery of stock promptly following the earliest to occur of (i) the
Executive’s death, (ii) the Executive’s disability (as defined in Section 409A
of the Internal Revenue Code of 1986, as amended (the “Code”)), (iii)
termination of the Executive’s employment, subject to Section 8(d), or (iv) a
date chosen by the Executive at the time of grant, which chosen date must be at
least three years after the grant date. The Options will vest in one-quarter
increments on each of the first four anniversaries of the grant date, if in
each case the Executive remains employed by the Company under this Agreement on
such anniversary. The actual number of shares of stock issued under the
Performance Shares will be determined in accordance with the Plan and terms
generally applicable to 2005 performance share grants to executive officers of
the Company, and the Performance Shares will vest over the period from their
grant to February 2008, subject to the Plan and other terms of this Agreement.
The Executive will be solely responsible for any taxes associated with the
receipt, vesting, exercise or delivery of shares or cash under the Promotion
Grants, and the Company will make appropriate withholdings from any
distributions of shares or cash thereunder.

	 	(C)	 	No Eligibility for Other Grants in 2005. A portion
of the Promotion Grants are made in lieu of any that would otherwise be made to
the Executive as part of the Company’s annual grant program for 2005, and,
accordingly, the Executive shall not receive any grants of DSUs or options
under such program in 2005, other than the Promotion Grants. The Executive will
be eligible to receive additional awards that the Company may undertake under
any other program, with respect to the Executive or otherwise, in 2005.

	 	(D)	 	Additional Grants After 2005. So long as he is
employed by the Company after 2005, the Executive shall receive grants of stock
options, performance shares and other equity-based awards, subject to the
applicable Company plans governing such awards, and covering a number of shares
as recommended by compensation consultants and determined by the compensation
committee of the Board. Since a portion of the Promotion Grants are made in
connection with the Executive’s promotion to President and CEO, future annual
awards may be smaller than the Promotion Grants.

	 	(c)	 	Tax and Financial Planning Assistance. The Executive will be entitled to receive up to
$15,000 per year in supplemental life insurance premiums, non-reimbursed medical expenses and
personal tax services at the Company’s expense and on a tax-assisted (or “fully grossed-up”)
basis.

	 	(d)	 	Other Benefits. The Executive will be entitled to participate in Company-paid executive
long-term disability insurance, Company-paid executive long-term care insurance, and
Company-paid basic life insurance programs, and to participate in the Company’s health
insurance, dental insurance, vision care, short-term disability and personal savings
(including 401(k) and 401(k) benefit restoration) plans, as well as other benefit plans and
fringe benefits and perquisites available to senior executives of the Company. Additionally,
while employed hereunder, the Executive shall be reimbursed (or the Company shall directly
pay) for the leasing, maintenance, insurance and operational costs for an automobile of his
choosing and approved by the Company, up to $2,000 per month, net of taxes. To the extent any
of the payments, perquisites or benefits under this Section 4(d) are taxable to the Executive,
they will be provided on a tax-assisted (or “fully grossed-up”) basis.

	 	(e)	 	Paid Vacation. While employed hereunder, the Executive shall be entitled to a minimum of
five weeks paid vacation per calendar year, such vacation to extend for such periods and to be
taken at such intervals as shall be appropriate and consistent with the proper performance of
the Executive’s duties hereunder.

	 	(f)	 	Business Expenses and Travel. While employed hereunder, the Executive shall be authorized to
incur and shall be reimbursed for all necessary and reasonable travel, entertainment and other
business expenses in connection with the Executive’s duties hereunder.

	 	(g)	 	Retirement. If the Executive retires upon or following the third anniversary of the
Effective Date and does not engage, and has no intention of engaging, in full-time employment
with a for-profit business enterprise (“Retires” or takes “Retirement”), or if, upon or
following such anniversary, the Company terminates the Executive’s employment for any reason
other than Cause (including as a result of his death or Disability) or the Executive
terminates his employment for Good Reason, then the Executive’s stock option and other equity
awards shall fully vest or be otherwise affected as if Section 7(a)(2) were effective with
respect thereto. For purposes of this Agreement and the retirement-related vesting provisions
of equity compensation under any equity compensation plans or agreements of the Company, or
with respect to any other benefit relating to retirement, the Executive shall be deemed to
have qualified for retirement under any applicable definition thereof, if he is an employee in
good standing on or after three years from the Effective Date, regardless of age.

	 	(h)	 	Legal Fee Reimbursement. The Company agrees to directly pay Executive’s reasonable advisory
and legal fees associated with entering into this Agreement, up to $5,000, upon receiving
invoices for such services. In the event of one or more disputes regarding this Agreement or
any other agreement relating to Executive’s employment with the Company or its successor that
arises on or after the occurrence of a Change in Control (as defined in Section 7 hereof), the
Company or its successor agrees to pay all of Executive’s legal fees and expenses associated
with such disputes.

	 	(i)	 	Indemnification. Executive shall receive indemnification as a corporate officer and director
of the Company to the maximum extent extended to the other officers and directors of the
Company. Following the termination of Executive’s employment or directorship for any reason,
the Company agrees to honor the indemnification agreement previously entered into with
Executive.

	 	 	 
	PART 2

Section 5.

	 	COMPENSATION AND BENEFITS IN CASE OF TERMINATION

WITHOUT CAUSE OR FOR GOOD REASON OUTSIDE OF A CHANGE OF

CONTROL

Terminations and Related Definitions
	 

	 	 

Part 2 of the Agreement, consisting of Sections 5 and 6, describes the benefits and compensation,
if any, payable in case of certain terminations of employment prior to six months before a Change
in Control and more than twelve months after a Change in Control.

In this Agreement,

	 	(a)	 	“Cause” means (1) a willful failure by the Executive to substantially perform the Executive’s
duties under this Agreement, other than a failure resulting from the Executive’s complete or
partial incapacity due to physical or mental illness or impairment, (2) a willful act by the
Executive that constitutes gross misconduct and that is materially injurious to the Company,
(3) a willful breach by the Executive of a material provision of this Agreement (including
Sections 8 or 10) or (4) a material and willful violation of a federal, state or foreign law
or regulation applicable to the business of the Company that is materially and demonstrably
injurious to the Company, provided that no act, or failure to act, by the Executive shall be
considered “willful” unless committed without good faith and without a reasonable belief that
the act or omission was in the Company’s best interest; and provided, further, that, if the
failure, act, breach or other basis for finding Cause under this Agreement is capable of being
cured without material injury to the Company, then no finding of Cause shall be made unless
the Executive has failed to cure such failure, act, breach or other basis within 30 days after
receiving written notice thereof from the Company, and

	 	(b)	 	“Disability” means that the Executive, at the time the notice is given, has been unable to
perform the Executive’s duties under this Agreement for a period of not less than six
consecutive months as a result of the Executive’s incapacity due to physical or mental
illness, and

	 	(c)	 	“Good Reason” means any of the following or as otherwise provided in this Agreement: (1) a
reduction in the Executive’s base salary other than as part of a broader executive pay
reduction, (2) a reduction in the Executive’s incentive compensation (EFIP) participation
level other than as part of a broader executive reduction, (3) a material change in the
employment benefits available to the Executive, if such change does not similarly affect all
employees of the Company eligible for such benefits, (4) a material reduction in Executive’s
duties, responsibilities or authority as then in effect, (5) a requirement to relocate, except
for office relocations that would not increase the Executive’s one-way commuting distance by
more than 35 miles, or (6) failure to recommend the Executive for re-election to the Board to
the FSII’s stockholders when his Board term expires or to re-election to the board of
directors of the Company.

Section 6.  Termination By Company Without Cause or By Executive for Good Reason 

(a) Severance. If the Company terminates the Executive’s employment for any reason
other than Cause (including as a result of the Executive’s death or Disability), or if the
Executive terminates his employment for Good Reason, then, provided the Executive (or his
legal representative, if applicable) executes the release of claims described in Section
6(b), and subject to Section 6(c), then the Company will promptly pay the Executive, in a
lump sum, an amount equal to two times the sum of (i) the Executive’s base salary in effect
on such termination date and (ii) the amount of the bonus the Executive would receive under
the Company’s Enhanced Fairchild Incentive Program (EFIP), assuming a 100% payout based on
the Executive’s base salary and EFIP incentive level in effect immediately prior to such
termination (whether or not such a bonus has been or is expected to be paid to other
executives or employees of the Company for the fiscal period in which such termination
occurs). If EFIP bonuses are later paid to EFIP participants at a level higher than 100% in
respect of the last fiscal period during which the Executive had been employed by the
Company, then the Company shall pay the Executive two times the difference between the
amount that would have been paid to the Executive had the Executive remained employed by the
Company, and been entitled to receive such bonus, and the amount determined under clause
(ii) above. If at the time of such a termination the EFIP program has been discontinued or
replaced, then the amount payable under clause (ii) above shall be the target or actual
amount that the Executive is entitled to receive under any incentive bonus program in which
he is then participating. The Executive will be responsible for all taxes relating to such
payments and the Company will make all required withholdings of all such taxes. In
addition, any of the 50,000 deferred stock units awarded to the Executive in connection with
his hiring by the Company in 2004 that are outstanding as of the date of such termination,
and which are not then vested, shall become fully vested and shall be considered to be
earned and payable in full, and any deferral or other restrictions on such DSUs shall lapse
and such DSUs shall be settled as promptly as is practicable following such termination. The
Executive will be responsible for all taxes relating to such payments and vesting and the
Company will make all required withholdings of all such taxes. In addition, the Company will
provide continued medical benefits for the Executive and his eligible dependents, under
COBRA coverage, at the Company’s expense for two years following the effective date of such
termination. At the time of such termination, the Company shall pay the Executive in cash
for all accrued and unused vacation time.

	 	(b)	 	Release of Claims. As a condition to the receipt of the payments and benefits
described in Section 6(a), the Executive (or his legal representative, if applicable) shall be
required to execute a release of all claims arising out of the Executive’s employment or the
termination thereof, including any claim of discrimination under U.S. state or federal law or
any non-U.S. law, but excluding claims for indemnification from the Company under any
indemnification agreement with the Company, its certificate of incorporation or bylaws, or
claims under applicable directors’ and officers’ insurance policies. If the Executive
executes such a release, then the Company shall release the Executive from all claims arising
out of the Executive’s employment with the Company, other than (i) any claims arising (before
or after termination) under Sections 8 or 10 of this Agreement and (ii) any claims arising
(before or after termination) from any violation by the Executive of any law or regulation.

	 	(c)	 	Conditions to Receipt of Payments. Without limiting the Company’s other rights or
remedies in the even of the Executive’s breach of any provision of this Agreement, the
obligation of the Company to provide the payments described in this Section 6 is subject to
the Executive’s continuing compliance with Sections 8 and 10 during and after the Term, and
also is subject to the related provisions of Section 11.

	 	(d)	 	No Mitigation. The Executive shall not be required to mitigate the amount of any
payment or benefit contemplated by this Section 6, nor shall any such payment or benefit be
reduced by any earnings or benefits that the Executive may receive from any other source.

	 	 	 
	PART 3

Section 7.

	 	COMPENSATION AND BENEFITS IN CASE OF A CHANGE IN CONTROL

Change in Control
	 

	 	 

	 	(a)	 	Payment; Vesting of Equity Awards. If the Executive’s employment is terminated by
the Company other than for Cause (including as a result of the Executive’s death or
Disability), or by the Executive for Good Reason, in either case within the time period
beginning six months before the Change in Control and ending 12 months after the Change in
Control, then

	 	(1)	 	the Company will promptly pay the Executive, in a lump sum, an amount
equal to three times the sum of (i) the Executive’s base salary in effect on such
termination date and (ii) the amount of the bonus the Executive would receive under
the Company’s Enhanced Fairchild Incentive Program (EFIP), assuming a 100% payout
based on the Executive’s base salary and EFIP incentive level in effect immediately
prior to such termination (whether or not such a bonus has been or is expected to
be paid to other executives or employees of the Company for the fiscal period in
which such termination occurs). If EFIP bonuses are later paid to EFIP participants
at a level higher than 100% in respect of the last fiscal period during which the
Executive had been employed by the Company, then the Company shall pay the
Executive three times the difference between the amount that would have been paid
to the Executive had the Executive remained employed by the Company, and been
entitled to receive such bonus, and the amount determined under clause (ii) above.
If at the time of such a termination the EFIP program has been discontinued or
replaced, then the amounts payable under clause (ii) above and the preceding
sentence shall be the maximum amounts that the Executive is entitled to receive
under any incentive bonus program in which he is then participating; and

	 	(2)	 	any stock options and stock appreciation rights granted to the
Executive that are outstanding as of the date of such termination, and which are
not then vested, shall become fully vested, and all stock options of the Executive
shall remain vested and exercisable for the full remaining term or terms thereof;
and any restrictions and deferral limitations applicable to any performance shares
or other restricted stock awards granted to the Executive that are outstanding as
of the date of such termination shall lapse, and such awards shall become free of
all restrictions and become fully vested and transferable; and all deferred stock
units granted to the Executive that are outstanding as of the date such termination
shall be considered to be earned and payable in full, and any deferral or other
restrictions shall lapse and such deferred stock units shall be settled as promptly
as is practicable following such termination. The Executive will be responsible for
all taxes relating to such payments and vesting and the Company will make all
required withholdings of all such taxes.

	 	(b)	 	Parachute Payment Full Gross-Up. In the event that the benefits provided for in this
Agreement or otherwise payable to the Executive constitute “parachute payments” within the
meaning of Section 280G of the Code and will be subject to the excise tax imposed by Section
4999 of the Code, then the Executive shall receive (i) a payment from the Company sufficient
to pay such excise tax, and (ii) an additional payment from the Company sufficient to pay the
excise tax and federal and state income taxes arising from the payments made by the Company to
Executive pursuant to this sentence. Unless the Company and the Executive otherwise agree in
writing, the determination of Executive’s excise tax liability and the amount required to be
paid under this Section 7(b) shall be made in writing by the Company’s independent registered
public accounting firm (as retained by the Company prior to the Change in Control) (the
“Accountants”). For purposes of making the calculations required by this Section 7(b), the
Accountants may make reasonable assumptions and approximations concerning applicable taxes and
may rely on reasonable, good faith interpretations concerning the application of Sections 280G
and 4999 of the Code. The Company and the Executive shall furnish to the Accountants such
information and documents as the Accountants may reasonably request in order to make a
determination under this Section. The Company shall bear all costs the Accountants may
reasonably incur in connection with any calculations contemplated by this Section 7(b).

	 	(c)	 	Definition. A “Change in Control” means the happening of any of the following events
(for purposes of this Section 7 only, the “Company” means FSII, and not any of its
subsidiaries) in one or a series of related transactions:

	 	(1)	 	An acquisition by any individual, entity or group (within the meaning of
Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended (the
“Exchange Act”)) (any of which, a “Person”) resulting in such Person having beneficial
ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 20%
or more of either (i) the then-outstanding shares of common stock of the Company (the
“Outstanding Company Common Stock”) or (ii) the combined voting power of the
then-outstanding voting securities of the Company entitled to vote generally in the
election of directors (the “Outstanding Company Voting Securities”); excluding,
however, the following: (A) Any acquisition directly from the Company, other than an
acquisition by virtue of the exercise of a conversion privilege unless the security
being so converted was itself acquired directly from the Company, (B) Any acquisition
by the Company, (C) Any acquisition by any employee benefit plan (or related trust)
sponsored or maintained by the Company or any entity controlled by the Company, or (D)
Any acquisition pursuant to a transaction which complies with clauses (i), (ii) and
(ii) of Section 7(b)(3); or

	 	(2)	 	A change in the composition of the board of directors of the Company (the
“Board”) such that the individuals who, as of the Effective Date, constitute the Board
(such Board shall be hereinafter referred to as the “Incumbent Board”) cease for any
reason to constitute at least a majority of the Board; provided, however, for purposes
of this definition, that any individual who becomes a member of the Board subsequent to
the Effective Date, whose election, or nomination for election by the Company’s
stockholders, was approved by a vote of at least a majority of those individuals who
are members of the Board and who were also members of the Incumbent Board (or deemed to
be such pursuant to this proviso) shall be considered as though such individual were a
member of the Incumbent Board; but, provided further, that any such individual whose
initial assumption of office occurs as a result of either an actual or threatened
election contest (as such terms are used in Rule 14a-11 of Regulation 14A promulgated
under the Exchange Act) or other actual or threatened solicitation of proxies or
consents by or on behalf of a Person other than the Board shall not be so considered as
a member of the Incumbent Board; or

	 	(3)	 	Consummation of a reorganization, merger or consolidation or sale or other
disposition of all or substantially all of the assets of the Company or the acquisition
of shares or assets of another company (“Corporate Transaction”); excluding, however,
such a Corporate Transaction pursuant to which (i) all or substantially all of the
individuals and entities who are the beneficial owners, respectively, of the
Outstanding Company Common Stock and Outstanding Company Voting Securities immediately
prior to such Corporate Transaction will beneficially own, directly or indirectly, more
than 50% of, respectively, the outstanding shares of common stock (or equity
interests), and the combined voting power of the then outstanding voting securities
entitled to vote generally in the election of directors (or equivalent governing body,
if applicable), as the case may be, of the entity resulting from such Corporate
Transaction (including an entity which as a result of such transaction owns the Company
or all or substantially all of the Company’s assets either directly or through one or
more subsidiaries) in substantially the same proportions as their ownership,
immediately prior to such Corporate Transaction, of the Outstanding Company Common
Stock and Outstanding Company Voting Securities, as the case may be, (ii) no Person
(other than the Company, any employee benefit plan (or related trust) of the Company or
such entity resulting from such Corporate Transaction) will beneficially own, directly
or indirectly, 20% or more of, respectively, the outstanding shares of common stock (or
equity interests) of the entity resulting from such Corporate Transaction or the
combined voting power of the outstanding voting securities of such corporation entitled
to vote generally in the election of directors (or equivalent governing body, if
applicable) except to the extent that such ownership existed prior to the Corporate
Transaction, and (iii) individuals who were members of the Incumbent Board will
constitute at least a majority of the members of the board of directors (or equivalent
governing body, if applicable) of the entity resulting from such Corporate Transaction;
or

	 	(4)	 	The approval by the stockholders of the Company of a complete liquidation or
dissolution of the Company.

	 	(d)	 	Any obligation of the Company under this Section 7 will survive any termination of this
Agreement.

result of the Executive’s employment, the Executive will be in a relationship of confidence
and trust with the Company and will come into possession of Confidential Information (as
defined below) that is (1) owned or controlled by the Company, (2) in the possession of the
Company and belonging to third parties or (3) conceived, originated, discovered or developed,

	 	(b)	 	Nondisclosure. The Executive agrees that the Executive will not, without the prior
written consent of the Company, directly or indirectly, use or disclose Confidential

The Executive will keep the Confidential Information in strictest confidence and trust. This
Section 8(b) shall apply indefinitely, both during and after the Term.

	 	(c)	 	Surrender Upon Termination. The Executive agrees that in the event of the
termination of the Executive’s employment for any reason, at any time, the Executive will
immediately deliver to the Company all property belonging to the Company, including documents
and materials of any nature pertaining to the Executive’s work with the Company, and will not
take with the Executive any documents or materials of any description, or any reproduction
thereof of any description, containing or pertaining to any Confidential Information. It is
understood that the Executive is free to use information that is in the public domain, but not
as a result of a breach of this Agreement

	 	(d)	 	Forfeiture in Certain Events. The Company may, in its sole discretion, in the event
of (i) any termination of employment of the Executive for Cause, (ii) any material breach by
the Executive of Section 10 following his termination of employment for any reason or (iii)
following a material breach of Section 10 and any finding of the invalidity or
unenforceability of Section 10 as further provided in Section 11, (A) cancel any outstanding
award of stock options, restricted stock, deferred stock units or other award granted to the
Executive under a Company plan or otherwise (an “Award”), in whole or in part, whether or not
vested or deferred, such cancellation to be effective as of a date specified in written notice
to the Executive, which date shall be no earlier than the date such notice is given, or (B)
following the exercise or payment of an Award, the Company may require the Executive to repay
to the Company any gain realized or payment received upon the exercise or payment of such
Award (with such gain or payment valued as of the date of exercise or payment). Such
repayment obligation shall be effective upon notice of demand thereof to Executive, and
repayment shall be due and payable to the Company as of a date which is at least 30 days after
the Executive receives such notice, which notice may provide for an offset to any future
payments owed by the Company or any subsidiary to the Executive if necessary to satisfy the
repayment obligation. Any determinations under this paragraph will be made by the Company in
good faith and in its sole discretion. This Section 8(d) shall apply during and following the
Term of this Agreement, but shall have no application following a Change in Control.

Section 9.  Assignment of Rights of Intellectual Property

The Executive will promptly and fully disclose all Intellectual Property to the Company. The
Executive hereby assigns and agrees to assign to the Company (or as otherwise directed by the
Company) the Executive’s full right, title and interest in and to all Intellectual Property. The
Executive will execute any and all applications for domestic and foreign patents, copyrights or
other proprietary rights and to do such other acts (including the execution and delivery of
instruments of further assurance or confirmation) requested by the Company to assign the
Intellectual Property to the Company and to permit the Company and its affiliates to enforce any
patents, copyrights or other proprietary rights to the Intellectual Property. “Intellectual
Property” means inventions, discoveries, developments, methods, processes, compositions, works,
concepts and ideas (whether or not patentable or copyrightable or constituting trade secrets)
conceived, made, created, developed or reduced to practice by the Executive (whether alone or with
others, whether or not during normal businesses hours or on or off Company premises) during the
Executive’s employment with the Company that relate to any business, venture or activity being
conducted or proposed to be conducted by the Company or its subsidiaries at any time during the
term of the Executive’s employment with the Company.

Section 10.  Restrictions on Activities of the Executive

	 	(a)	 	Acknowledgments. The Executive agrees that he is being employed under this Agreement
in a key management capacity with the Company, that the Company is engaged in a highly
competitive business and that the success of the Company’s business in the marketplace depends
upon its goodwill and reputation for quality and dependability. The Executive further agrees
that reasonable limits may be placed on his ability to compete against the Company and its
affiliates as provided in this Agreement so as to protect and preserve their legitimate
business interests and goodwill.

(b) Agreement Not to Compete or Solicit.

	 	(1)	 	During the Non-Competition Period (as defined below), the Executive will not
engage or participate in, directly or indirectly, as principal, agent, employee,
corporation, consultant, investor or partner, or assist in the management of, any
business which is Competitive with the Company (as defined below).

	 	(2)	 	During the Non-Competition Period, the Executive will not, directly or
indirectly, through any other entity, solicit for hire any officer, director,
consultant, executive or employee of the Company or any of its affiliates during his or
her engagement with the Company or such affiliate. During the Non-Competition Period,
the Executive will not call upon, solicit, divert or attempt to solicit or divert from
the Company or any of its affiliates any of their customers or suppliers or potential
customers or suppliers of whose names he was aware during his term of employment (other
than customers or suppliers or potential customers or suppliers contacted by the
Executive solely in connection with a business that is not Competitive with the
Company).

	 	(3)	 	The “Non-Competition Period” means the period during which Executive is
employed by the Company and the following 12 months.

	 	(4)	 	A business shall be considered “Competitive with the Company” if it is engaged
in any business, venture or activity in the Restricted Area (as defined below) which
competes or plans to compete with any business, venture or activity being conducted or
actively and specifically planned to be conducted within the Non-Competition Period (as
evidence by the Company’s internal written business plans or memoranda) by the Company,
or any group, division or affiliate of the Company, at the date the Executive’s
employment under this Agreement is terminated.

	 	(5)	 	The “Restricted Area” means the United States of America and any other country
where the Company, or any group, division or affiliate of the Company, is conducting,
or has proposed to conduct within the Non-Competition Period (as evidenced by the
Company’s internal written business plans or memoranda), any business, venture or
activity, at the date the Executive’s employment under this Agreement is terminated.

	 	(6)	 	Notwithstanding the provisions of this Section 10, the parties agree that (A)
ownership of not more than three percent (3%) of the voting stock of any publicly held
corporation or one percent (1%) of the voting stock of a privately held corporation or
other entity, shall not, of itself, constitute a violation of this Section 10 and (B)
working as an employee of an entity that has a stand-alone division or business unit
which is Competitive with the Company shall not, of itself, constitute a violation of
this Section 10 if the Executive is not, in any way (directly or indirectly, as
principal, agent, employee, corporation, consultant, advisor, investor or partner),
responsible for, compensated with respect to, or involved in the activities of such
stand-alone division or business unit and does not (directly or indirectly) provide
information or assistance to such stand-alone division or business unit.

Section 11.  Remedies

It is specifically understood and agreed that any breach of the provisions of Section 8 or 10 of
this Agreement would likely result in irreparable injury to the Company and that the remedy at law
alone would be an inadequate remedy for such breach, and that in addition to any other remedy it
may have, the Company shall be entitled to enforce the specific performance of this Agreement by
the Executive and to obtain both temporary and permanent injunctive relief without the necessity of
proving actual damages. Without limiting the generality of the foregoing provisions of this Section
11, it is understood and agreed that the Promotion Grants under Section 4(b) and the Company’s
promise to provide the severance payments and other benefits described in Section 6(a) are made
subject to the condition that (i) the Executive’s obligations under Section 10 are and will remain
specifically enforceable against the Executive in accordance with those sections and (ii) if, in an
action by the Company against the Executive for the breach or alleged breach of Section 10, a court
of competent jurisdiction finds that all or any part of those sections is invalid or unenforceable
for any reason, then the Company may, without limiting its other remedies at law or equity, enforce
all of the remedies available to it under this Agreement, including without limitation the remedies
described in Section 8(d).

Section 12.  Severable Provisions

The provisions of this Agreement are severable and the invalidity of any one or more provisions
shall not affect the validity of any other provision. In the event that a court of competent
jurisdiction shall determine that any provision of this Agreement or the application thereof is
unenforceable in whole or in part because of the duration of scope thereof, the parties hereby
agree that such court, in making such determination, shall have the power to reduce the duration
and scope of such provision to the extent necessary to make it enforceable and that this Agreement
in its reduced form shall be valid and enforceable to the fullest extent permitted by law.

Section 13.  Successors

	 	(a)	 	Company’s Successors. The Company will require any successor (whether direct or
indirect and whether by purchase, lease, merger, consolidation, liquidation or otherwise) to
all or substantially all of the Company’s business or assets, by an agreement in substance and
form satisfactory to the Executive, to assume this Agreement and to agree expressly to perform
this Agreement in the same manner and to the same extent as the Company would be required to
perform it in the absence of a succession. The Company’s failure to obtain such agreement
prior to the effectiveness of a succession shall be a breach of this Agreement and shall
entitle the Executive to all of the compensation and benefits to which the Executive would
have been entitled under this Agreement if the Company had terminated the Executive’s
employment for any reason other than Cause, on the date when such succession becomes
effective. For all purposes under this Agreement, except as otherwise provided in this
Agreement, the term “Company” shall include any successor to the Company’s business or assets
that executes and delivers the assumption agreement described in this Section 13(a), or that
becomes bound by this Agreement by operation of law.

	 	(b)	 	Executive’s Successors. This Agreement and all rights of the Executive under this
Agreement shall inure to the benefit of, and be enforceable by, the Executive’s personal or
legal representatives, executors, administrators, successors, heirs, distributees, devisees
and legatees.

Section 14.  General Provisions

	 	(a)	 	Amendment; Waiver. No provision of this Agreement shall be modified, waived or
discharged unless the modification, waiver or discharge is agreed to in writing and signed by
the Executive and by an authorized officer of the Company (other than the Executive). No
waiver by either party of any breach of, or of compliance with, any condition or provision of
this Agreement by the other party shall be considered a waiver of any other condition or
provision or of the same condition or provision at another time.

	 	(b)	 	Whole Agreement; Interpretation. No agreements, representations or understandings
(whether oral or written and whether express or implied) that are not expressly set forth in
this Agreement have been made or entered into by either party with respect to the subject
matter hereof. The reference table on the first page and the headings in this Agreement are
for convenience of reference only and will not affect the construction or interpretation of
this Agreement. The word “or” is used in its non-exclusive sense. Unless otherwise stated,
the word “including” should be read to mean “including without limitation” and does not limit
the preceding words or terms. All references to “Sections” or other provisions in this
Agreement are to the corresponding Sections or provisions in this Agreement. All words in
this Agreement will be construed to be of such gender or number as the circumstances require.

	 	(c)	 	Notice. Notices and all other communications contemplated by this Agreement shall be
in writing and shall be deemed to have been duly given when personally delivered, mailed by
U.S. registered or certified mail, return receipt requested, or sent by a documented overnight
courier service. In the case of the Executive, mailed notices shall be addressed to the
Executive at the home address maintained in the Company’s records. In the case of the
Company, mailed notices shall be addressed to its corporate headquarters, and all notices
shall be directed to the attention of the Chairman of the Board of Directors, with a required
copy to the attention of the Corporate Secretary.

	 	(d)	 	Setoff. The Company may set off against any payments owed to the Executive under
this Agreement any debt or obligation of the Executive owed to the Company.

	 	(e)	 	Choice of Law. The validity, interpretation, construction and performance of this
Agreement shall be governed by the laws of the State of Maine, irrespective of Maine’s
choice-of-law principles.

	 	(f)	 	Arbitration. Except as otherwise provided with respect to the enforcement of
Sections 8 and 10, any dispute or controversy arising out of the Executive’s employment or the
termination thereof, including any claim of discrimination under U.S. (state or federal) or
non-U.S. law, shall be settled exclusively by arbitration in Portland, Maine, in accordance
with the rules of the American Arbitration Association then in effect. Judgment may be
entered on the arbitrator’s award in any court having jurisdiction.

	 	(g)	 	No Assignment of Benefits. The rights of any person to payments or benefits under
this Agreement shall not be made subject to option or assignment, either by voluntary or
involuntary assignment or by operation of law, including bankruptcy, garnishment, attachment
or other creditor’s process, and any action in violation of this Section 14(g) shall be void.

	 	(h)	 	Limitation of Remedies. If the Executive’s employment terminates for any reason, the
Executive shall not be entitled to any payments, benefits, damages, awards or compensation
other than as provided by this Agreement, including under the severance policies of the
Company or any subsidiary.

	 	(i)	 	Taxes. Except where specified in this Agreement as “tax protected” or subject to a
gross-up, all payments made pursuant to this Agreement shall be subject to withholding of
applicable taxes. This Agreement will be deemed amended to the extent necessary to avoid
imposition of any additional tax or income recognition prior to actual payment to Executive
under Internal Revenue Code section 409A and any temporary or final Treasury Regulations and
guidance promulgated thereunder (“Code Section 409A”). In the event that any additional taxes
or interest are due and payable from Executive to the Internal Revenue Service under Code
Section 409A as a result of any payments or benefits payable hereunder, the Company shall
provide Executive with additional payments so that Executive is fully grossed-up with the
respect to the Code Section 409A payments.

	 	(j)	 	Discharge of Responsibility. The payments and other benefits under this Agreement,
when made in accordance with the terms of this Agreement, shall fully discharge all
responsibilities of the Company to the Executive that existed at the time of termination of
the Executive’s employment.
