                         MANAGEMENT CONTINUITY AGREEMENT

     THIS MANAGEMENT CONTINUITY AGREEMENT (the "Agreement") is entered into
effective as of the ______ day of _____, 2000, between ____________,
("Employee") and AVIRON, a Delaware corporation (the "Company"). This Agreement
is intended to provide Employee with certain benefits described herein upon the
occurrence of specific events. Certain capitalized terms used in this Agreement
are defined in Article 4.

                                    RECITALS

     A.   It is expected that another company may from time to time consider the
possibility of acquiring the Company or that a change of control may otherwise
occur, with or without the approval of the Company's Board of Directors. The
Board of Directors recognizes that such consideration can be a distraction to
Employee and can cause Employee to consider alternative employment
opportunities. The Board of Directors has determined that it is in the best
interests of the Company and its stockholders to assure that the Company will
have the continued dedication and objectivity of the Employee, notwithstanding
the possibility, threat or occurrence of a Change of Control (as defined below)
of the Company.

     B.   The Company's Board of Directors believes it is in the best interests
of the Company and its stockholders to retain Employee and provide incentives to
Employee to continue in the service of the Company.

     C.   The Board of Directors further believes that it is imperative to
provide Employee with certain benefits upon a Change of Control and, under
certain circumstances, upon termination of Employee's employment in connection
with a Change of Control, which benefits are intended to provide Employee with
financial security and provide sufficient income and encouragement to Employee
to remain with the Company, notwithstanding the possibility of a Change of
Control.

     D.   To accomplish the foregoing objectives, the Board of Directors has
directed the Company, upon execution of this Agreement by Employee, to agree to
the terms provided in this Agreement.

     Now therefore, in consideration of the mutual promises, covenants and
agreements contained herein, and in consideration of the continuing employment
of Employee by the Company, the parties hereto agree as follows:

                                    ARTICLE 1

                                CHANGE OF CONTROL

     1.1  TERMINATION EVENTS. If Employee's employment terminates under
circumstances constituting a Covered Termination upon or within eighteen (18)
months

<PAGE>   2

following a Change of Control of the ownership of the Company, Employee shall be
entitled to receive the following benefits set forth in Sections 1.2, 1.3 and
1.4.

     1.2  SALARY CONTINUATION. Employee shall receive Base Salary that has
accrued but is unpaid as of the date of such Covered Termination, and, within
thirty (30) days following such Covered Termination, Employee also shall receive
a lump sum payment equal to one year of the base salary which the employee was
receiving immediately prior to the Change of Control and the Employee's targeted
bonus for the fiscal year in which the Change of Control occurs.

     1.3  HEALTH INSURANCE COVERAGE IN THE EVENT OF CHANGE OF CONTROL:

          Provided that Employee makes a timely election to continue coverage
under the Company's group health plan pursuant to the Consolidated Omnibus
Budget Reconciliation Act of 1985 ("COBRA") in connection with Employee's
Covered Termination, the Company will pay Employee's COBRA premiums for a
maximum period of one (1) year following the date of such Covered Termination
(the "COBRA Continuation Period"). In addition, if Employee's spouse and/or
dependents were enrolled in the Company's group health plan on the date of the
Covered Termination, the Company will pay the COBRA premiums for Employee's
dependents during the COBRA Continuation Period, but only to the same extent
that such dependents' premiums under such plan were paid by the Company prior to
the date of such Covered Termination. No provision of this Agreement will affect
the continuation coverage rules under COBRA, except that the Company's payment
of any applicable premiums during the COBRA Continuation Period will be credited
as payment by Employee for purposes of the Employee's payment required under
COBRA. Therefore, the period during which Employee must elect to continue the
Company's group health coverage at his or her own expense under COBRA, the
length of time during which COBRA coverage will be made available to Employee,
and all other rights and obligations of the Employee under COBRA (except the
obligation to pay premiums that the Company pays during the COBRA Continuation
Period) will be applied in the same manner that such rules would apply in the
absence of this Agreement. At the conclusion of the COBRA Continuation Period,
Employee will be responsible for the entire payment of premiums required under
COBRA for the remaining duration of eligibility for COBRA, if any.

          Notwithstanding the foregoing, the Company's obligation to make COBRA
payments for Employee shall cease immediately if Employee becomes eligible for
other health insurance benefits at the expense of a new employer. Employee
agrees to notify a duly authorized officer of the Company, in writing,
immediately upon acceptance of any employment following the Covered Termination
which provides Employee with eligibility for health insurance benefits.

     1.4  ACCELERATION OF VESTING OF OUTSTANDING OPTIONS. In the event of a
Covered Termination where the Company has assumed or substituted the Employee's
options in connection with the Change of Control, the vesting of outstanding
stock options to purchase common stock of the Company granted to Employee prior
to the date of termination of employment shall accelerate as of the date of such
Covered Termination so that all outstanding options are one hundred percent
(100%) vested and immediately exercisable. Such acceleration of vesting of
outstanding options also shall apply to any unvested option shares that were
acquired by Employee on or before the date of the Covered Termination and that
were subject to


                                       2
<PAGE>   3

a repurchase option by the Company as of such date. Where the Company does not
assume or substitute the Employee's options in connection with a Change of
Control, one hundred percent (100%) of options will vest immediately prior to a
Change of Control.

     1.5  PARACHUTE PAYMENTS. In the event that the acceleration of the vesting
provided for in Section 1.4 and benefits otherwise payable to Employee (i)
constitute "parachute payments" within the meaning of Section 280G of the
Internal Revenue Code of 1986, as amended, (the "Code"), or any comparable
successor provision, and (ii) but for this section would be subject to the
excise tax imposed by Section 4999 of the Code, or any comparable successor
provision (the "Excise Tax"), then Employee's benefits hereunder shall be either

          (i)  provided to Employee in full, or

          (ii) provided to Employee as to such lesser extent which would result
               in no portion of such benefits being subject to the Excise Tax,

whichever of the foregoing amounts, when taking into account applicable federal,
state, local and foreign income and employment taxes, the Excise Tax, and any
other applicable taxes, results in the receipt by Employee, on an after-tax
basis, of the greatest amount of benefits, notwithstanding that all or some
portion of such benefits may be taxable under the Excise Tax. Unless the Company
and Employee otherwise agree in writing, any determination required under this
section shall be made in writing in good faith by the Accountants. In the event
of a reduction of benefits hereunder, benefits payable in cash shall be reduced
first. For purposes of making the calculations required by this section, the
Accountants may make reasonable assumptions and approximations concerning
applicable taxes and may rely on reasonable, good faith interpretations
concerning the application of the Code, and other applicable legal authority.
The Company and Employee 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.

     If, notwithstanding any reduction described in this section, the IRS
determines that Employee is liable for the Excise Tax as a result of the receipt
of the payment of benefits as described above, then Employee shall be obligated
to pay back to the Company, within thirty (30) days after a final IRS
determination or in the event that Employee challenges the final IRS
determination, a final judicial determination, a portion of the payment equal to
the "Repayment Amount." The Repayment Amount with respect to the payment of
benefits shall be the smallest such amount, if any, as shall be required to be
paid to the Company so that Employee's net after-tax proceeds with respect to
any payment of benefits (after taking into account the payment of the Excise Tax
and all other applicable taxes imposed on such payment) shall be maximized. The
Repayment Amount with respect to the payment of benefits shall be zero if a
Repayment Amount of more than zero would not result in Employee's net after-tax
proceeds with respect to the payment of such benefits being maximized. If the
Excise Tax is not eliminated pursuant to this paragraph, Employee shall pay the
Excise Tax.

     Notwithstanding any other provision of this Section 1.5, if (i) there is a
reduction in the payment of benefits as described in this section, (ii) the IRS
later determines that

                                       3
<PAGE>   4

Employee is liable for the Excise Tax, the payment of which would result in the
maximization of Employee's net after-tax proceeds (calculated as if Employee's
benefits had not previously been reduced), and (iii) Employee pays the Excise
Tax, then the Company shall pay to Employee those benefits which were reduced
pursuant to this section contemporaneously or as soon as administratively
possible after Employee pays the Excise Tax so that Employee's net after-tax
proceeds with respect to the payment of benefits is maximized.

                                   ARTICLE 3

                     LIMITATIONS AND CONDITIONS ON BENEFITS

     3.1  WITHHOLDING OF TAXES. The Company shall withhold appropriate federal,
state, local (and foreign, if applicable) income and employment taxes from any
payments hereunder.

     3.2  RELEASE PRIOR TO RECEIPT OF BENEFITS. Upon the occurrence of a Covered
Termination, and prior to the receipt of any benefits under this Agreement on
account of the occurrence of such Covered Termination, Employee shall execute a
release (the "Release") in the form incorporated herein and attached hereto as
Attachment I. Such Release shall specifically relate to all of Employee's rights
and claims in existence at the time of such execution and shall confirm
Employee's obligations under the Company's standard form of proprietary
information agreement. It is understood that Employee has twenty-one (21) days
to consider whether to execute such Release, and Employee may revoke such
Release within seven (7) business days after execution. In the event Employee
does not execute such Release within the twenty-one (2l)-day period, or if
Employee revokes such Release within the subsequent seven (7) business day
period, no benefits shall be payable under this Agreement and this Agreement
shall be null and void. Notwithstanding the foregoing, in addition to or in lieu
of the release contained in Attachment I, Employee may be required to execute
and deliver an effective release in such other form as the Company may, in its
sole discretion, determine to be necessary or appropriate in order to comply
with the requirements of the laws of any jurisdiction applicable to Employee in
order to make a general release of claims effective and enforceable.

                                   ARTICLE 4

                            OTHER RIGHTS AND BENEFITS

     4.1  NONEXCLUSIVITY. Except as otherwise expressly provided herein, nothing
in the Agreement shall prevent or limit Employee's continuing or future
participation in any benefit, bonus, incentive or other plans, programs,
policies or practices provided by the Company and for which Employee may
otherwise qualify, nor shall anything herein limit or otherwise affect such
rights as Employee may have under other agreements with the Company. Except as
otherwise expressly provided herein, amounts which are vested benefits or which
Employee is otherwise entitled to receive under any plan, policy, practice or
program of the Company at or subsequent to the date of a Covered Termination
shall be payable in accordance with such plan, policy, practice or program.

     4.2  NON-DUPLICATION OF BENEFITS. Notwithstanding any other provision of
the Agreement to the contrary, any benefits payable to Employee under this
Agreement shall be in



                                       4
<PAGE>   5

lieu of any severance benefits payable by the Company to such individual under
any other arrangement covering the individual, unless expressly otherwise agreed
to by the Company in writing.

                                   ARTICLE 5

                                  ATTACHMENT I

                                     RELEASE

     Certain capitalized terms used in this Release are defined in the
Management Continuity Agreement (the "Agreement") which I have executed and of
which this Release is a part.

     I hereby confirm my obligations under the Company's proprietary information
and inventions agreement.

     Except as otherwise set forth in this Release, I hereby release, acquit and
forever discharge the Company, its parents and subsidiaries, and their officers,
directors, agents, servants, employees, shareholders, successors, assigns and
affiliates, of and from any and all claims, liabilities, demands, causes of
action, costs, expenses, attorneys fees, damages, indemnities and obligations of
every kind and nature, in law, equity, or otherwise, known and unknown,
suspected and unsuspected, disclosed and undisclosed (other than any claim for
indemnification I may have as a result of any third party action against me
based on my employment with the Company), arising out of or in any way related
to agreements, events, acts or conduct at any time prior to the date I execute
this Release, including, but not limited to: all such claims and demands
directly or indirectly arising out of or in any way connected with my employment
with the Company or the termination of that employment, including but not
limited to, claims of intentional and negligent infliction of emotional
distress, any and all tort claims for personal injury, claims or demands related
to salary, bonuses, commissions, stock, stock options, or any other ownership
interests in the Company, vacation pay, fringe benefits, expense reimbursements,
severance pay, or any other form of disputed compensation; claims pursuant to
any federal, state or local law or cause of action including, but not limited
to, the federal Civil Rights Act of 1964, as amended; the federal Age
Discrimination in Employment Act of 1967, as amended ("ADEA"); the federal
Employee Retirement Income Security Act of 1974, as amended; the federal
Americans with Disabilities Act of 1990; tort law; contract law; statutory law;
common law; wrongful discharge; discrimination; fraud; defamation; emotional
distress; and breach of the implied covenant of good faith and fair dealing;
provided, however, that nothing in this paragraph shall be construed in any way
to release the Company from its obligation to indemnify me pursuant to the
Company's indemnification obligation pursuant to agreement or applicable law.

     In giving this release, which includes claims that may be unknown to me at
present, I acknowledge that I have read and understand Section 1542 of the
California Civil Code which reads as follows: "A GENERAL RELEASE DOES NOT EXTEND
TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT
THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY
AFFECTED HIS SETTLEMENT WITH THE DEBTOR." I expressly waive and relinquish all
rights and benefits under that section and any law of any jurisdiction of
similar effect with respect to my release of any unknown or unsuspected claims I
may have against the Company.


                                       9

     I acknowledge that I am knowingly and voluntarily waiving and releasing any
rights I may have under ADEA. I also acknowledge that the consideration given
under the Agreement for the waiver and release in the preceding paragraph hereof
is in addition to anything of value to which I was already entitled. I further
acknowledge that I have been advised by this writing, as required by the ADEA,
that: (A) my waiver and release do not apply to any rights or claims that may
arise on or after the date I execute this Release; (B) I have the right to
consult with an attorney prior to executing this Release; (C) I have twenty-one
(21) days to consider this Release (although I may choose to voluntarily execute
this Release earlier); (D) I have seven (7) days following the execution of this
Release by the parties to revoke the Release; and (E) this Release shall not be
effective until the date upon which the revocation period has expired, which
shall be the eighth day after this Release is executed by me.
