                                     Part II

               Information Required in the Registration Statement

         On April 28, 1997,  AGOURON  PHARMACEUTICALS,  INC.  (the  "Company" or
"Registrant") and Alanex Corporation,  a Delaware  corporation,  entered into an
Agreement and Plan of Reorganization (the "Merger  Agreement").  Pursuant to the
Merger Agreement,  on May 23, 1997 Alanex  Corporation  merged with and became a
wholly owned  subsidiary of the  Registrant.  Registrant  assumed all options to
purchase  common stock of Alanex  Corporation  issued under  Alanex's 1993 Stock
Plan,  as amended,  its 1996  Equity  Incentive  Plan and  pursuant to any other
outstanding option agreements.

Item 3.  Incorporation of Documents by Reference.

         The following documents filed by the Registrant with the Securities and
Exchange   Commission  are  incorporated  by  reference  in  this   Registration

                  ended June 30, 1996;

         (2)      The Company's  Quarterly Reports on Form 10-Q for the quarters

         (3)      The description of the Company's Common Stock contained in the

                  Services,  L.L.C., including any amendment or report filed for

         In addition,  all documents  subsequently filed by the Company pursuant

documents.

         Gary E. Friedman,  Esq., who has provided the opinion to the Registrant

5 to  this  Registration  Statement,  is Vice  President,  General  Counsel  and
Secretary of the Registrant.

<PAGE>

Item 6.  Indemnification of Directors and Officers.

     Section 317 of the California  General  Corporation Law generally  provides
indemnification  to officers  and  directors  of the Company  against  expenses,
judgments,  fines and amounts paid in settlement  under certain  conditions  and
subject to certain limitations.

     Article VII of the articles of  incorporation  of the Company provides that
liability  of the  directors  of the  Company  for  monetary  damages  shall  be
eliminated to the fullest extent  permissible  under  California  law.  Further,
Article  VIII of the articles of  incorporation  of the Company  authorizes  the
Company to provide  indemnification  of agents (as  defined in Section  317) for
breach of duty to the Company and its  shareholders  through bylaw provisions or
through  agreements with such agents, or both, in excess of the  indemnification
otherwise  permitted  by  Section  317,  subject  to the  limits on such  excess
indemnification set forth in Section 317.

     Section  3.15 of the  bylaws  of the  Company  authorizes  the  Company  to
indemnify any person who was or is a party, or is threatened to be made a party,
to any  proceeding  (other  than  actions  by or in the right of the  Company to
procure a judgment  in its  favor) by reason of the fact that such  person is or
was an agent of the Company, against expenses, judgments, fines, settlements and
other  amounts  actually  and  reasonably   incurred  in  connection  with  such
proceeding  if such  person  acted in good  faith  and in a manner  such  person
reasonably  believed to be in the best  interests of the  Company.  Section 3.15
also authorizes the Company to indemnify any person who was or is a party, or is
threatened to be made a party, to any threatened, pending or completed action by
or in the right of the  Company to procure a judgment  in its favor by reason of
the fact that such person is or was an agent of the  Company,  against  expenses
actually and reasonably  incurred by such person in connection  with the defense
or settlement of such action if such person acted in good faith.

     Any indemnification under Section 3.15 is to be made by the Company only if
authorized in the specific case upon determination  that  indemnification of the
agent is proper in the  circumstances  because the agent has met the  applicable
standard of conduct required by Paragraphs 3.15.2 or 3.15.3 of the bylaws.

     Pursuant to authorization  provided under the articles of incorporation and
the bylaws, the Company has entered into indemnification agreements with each of
its present directors. The Company has also entered into similar agreements with
certain  of the  Company's  officers  who  are  not  directors.  Generally,  the
indemnification  agreements attempt to provide the maximum protection  permitted
by  California  law as it may be  amended  from  time  to  time.  Moreover,  the
indemnification agreements provide for certain additional indemnification. Under
such  additional  indemnification  provisions,  however,  an individual will not
receive  indemnification for judgments,  settlements or expenses if he or she is
found liable to the Company (except to the extent the court determines he or she
is fairly and reasonably entitled to indemnity for expenses) for settlements not
approved by the Company or for settlements and expenses if the settlement is not
approved by the court. The indemnification agreements provide for the Company to
advance to the individual any and all reasonable  expenses (including legal fees
and expenses)  incurred in investigating  or defending any such action,  suit or
proceeding.  In order to receive an advance of  expenses,  the  individual  must
submit  to the  Company  copies  of  invoices  presented  to him or her for such
expenses.  Also, the  individual  must repay such advances upon a final judicial
decision that he or she is not entitled to indemnification.

<PAGE>

     Section  3.15  of  the  bylaws  also  provides  that,  in  the  event  of a
determination by the Board of Directors of the Company to purchase insurance for
certain of its agents,  the Company  shall  purchase and  maintain  insurance on
behalf of any such agent against  liability  asserted against or incurred by the
agent in such capacity or arising out of the agent's status,  whether or not the
Company would have the power to indemnify the agent against such liability under
the provisions of Section 3.15.

     The  Company  has in effect  directors  and  officers  liability  insurance
policies  which  insure  directors  and  officers of the  Company.  Although the
Company intends to renew the policies on or before their  expiration date, there
can be no assurance that the policies will be renewed on terms acceptable to the
Company.  Under the  policies,  the  directors  and  officers of the Company are
insured  against loss arising from claims made against them due to wrongful acts
while acting in their  individual  and  collective  capacities  as directors and
officers,  subject to certain exclusions.  In addition,  the policies insure the
Company  against  losses for which its  directors  and  officers are entitled to
indemnification,  subject to certain  retentions  payable  by the  Company.  The
policies are "claims made" policies and provide coverage only for losses arising
out of claims first made against the Company and reported to the insurer  during
the policy period.

Item 9.  Undertakings.

         (a)      The undersigned Registrant hereby undertakes:

                  (1) To file,  during any  period in which  offers or sales are
                  being made, a  post-effective  amendment to this  Registration
                  Statement:

                           (i)      to include any  prospectus  required by 
                           Section  10(a)(3) of the Securities Act of 1933;

                           (ii) to reflect in the prospectus any facts or events
                           arising after the effective date of this Registration
                           Statement   (or  the   most   recent   post-effective
                           amendment  hereof)  which,  individually  or  in  the
                           aggregate,  represent  a  fundamental  change  in the
                           information set forth in this Registration Statement;

                           (iii)  to  include  any  material   information  with
                           respect to the plan of  distribution  not  previously
                           disclosed  in  this  Registration  Statement  or  any
                           material   change   to  such   information   in  this
                           Registration Statement;

         provided,  however,  that  paragraphs  (a)(l)(i) and  (a)(l)(ii) do not
         apply if the  information  required to be included in a  post-effective
         amendment by those paragraphs is contained in periodic reports filed by
         the  Registrant  pursuant  to  Section  13  or  Section  15(d)  of  the
         Securities  Exchange Act of 1934 that are  incorporated by reference in
         this Registration Statement.

                  (2) That, for the purpose of determining  any liability  under
                  the Securities Act of 1933, each such post-effective amendment
                  shall be deemed to be a new registration statement relating to
                  the  securities  offered  therein,  and the  offering  of such
                  securities at that time shall be deemed to be the initial bona
                  fide offering thereof.

                  (3) To remove from  Registration by means of a  post-effective
                  amendment any of the securities  being registered which remain
                  unsold at the termination of the offering.

         (b) The undersigned  Registrant hereby undertakes that, for purposes of
         determining any liability under the Securities Act of 1933, each filing
         of the 

<PAGE>

         Registrant's  annual report pursuant to Section 13(a) or Section
         15(d) of the  Securities  Exchange  Act of 1934 (and each filing of the
         annual report of the Plan  pursuant to Section 15(d) of the  Securities
         Exchange  Act of  1934)  that  is  incorporated  by  reference  in this
         Registration  Statement  shall  be  deemed  to  be a  new  registration
         statement relating to the securities offered therein,  and the offering
         of such  securities at that time shall be deemed to be the initial bona
         fide offering thereof.

         (c)  Insofar  as  indemnification  for  liabilities  arising  under the
         Securities  Act of 1933 may be  permitted  to  directors,  officers and
         controlling  persons  of  the  Registrant  pursuant  to  the  foregoing
         provisions,  or otherwise,  the Registrant has been advised that in the
         opinion of the Securities and Exchange Commission such  indemnification
         is against  public  policy as expressed  in the Act and is,  therefore,
         unenforceable.  In the event that a claim for  indemnification  against
         such liabilities  (other than the payment by the Registrant of expenses
         incurred or paid by a director,  officer or  controlling  person of the
         Registrant in the successful defense of any action, suit or proceeding)
         is  asserted  by  such  director,  officer  or  controlling  person  in
         connection with the securities being  registered,  the Registrant will,
         unless in the  opinion of its  counsel  the matter has been  settled by
         controlling  precedent,  submit to a court of appropriate  jurisdiction
         the  question  whether  such  indemnification  by it is against  public
         policy  as  expressed  in the Act and  will be  governed  by the  final
         adjudication of such issue.

            (b)       The Board  shall have the power,  subject to, and within
the  limitations  of, the express provisions of the Plan:

                     (1)          To  determine  from time to time which of the
persons  eligible  under the Plan shall be  granted  Stock  Awards;  when and

a Stock Award;  and the number of shares with respect to which Stock Awards

                     (2)          To construe  and  interpret  the Plan and
Stock Awards  granted  under it,  and  to  establish,   amend  and  revoke

to a Committee,  the Committee shall have, in connection with the administration
of the Plan, the powers  theretofore  possessed by the Board (and  references in
this Plan to the Board shall thereafter be to the Committee),  subject, however,
to such resolutions, not inconsistent with the provisions of the Plan, as may be
adopted from time to time by the Board.  The Board may abolish the  Committee at
any time and revest in the Board the  administration of the Plan.  Additionally,
prior to the date of the first registration of an equity security of the Company
under  Section 12 of the  Exchange  Act,  and  notwithstanding  anything  to the
contrary herein, the Board may delegate administration of the Plan to any person

Disinterested  Person  shall  not  apply  (i)  prior  to the  date of the  first
registration  of an equity  security  of the  Company  under  Section  12 of the
Exchange Act, or (ii) if the Board or the Committee expressly declares that such
requirement  shall not apply.  Any  Disinterested  Person shall otherwise comply
with the requirements of Rule 16b-3.

4.            SHARES SUBJECT TO THE PLAN.

              (a)  Subject  to  the   provisions   of  Section  13  relating  to
adjustments  upon  changes in stock,  the stock that may be issued  pursuant  to
Stock Awards shall not exceed in the  aggregate  one million three hundred fifty
thousand  (1,350,000)  shares of the Company's  common stock. If any Stock Award
shall for any reason expire or otherwise terminate without having been exercised
in full,  the stock not  purchased  under such Stock Award  shall  again  become
available for the Plan.

              (b)       The  stock  subject  to the Plan may be  unissued
shares  or  reacquired  shares, bought on the market or otherwise.

5.            ELIGIBILITY.

              (a)  Incentive  Stock  Options may be granted  only to  Employees.
Stock  Awards  other  than  Incentive  Stock  Options  may be  granted  only  to
Employees, Directors or Consultants.

              (b) A Director  shall in no event be eligible  for the benefits of
the Plan unless at the time  discretion  is  exercised  in the  selection of the
Director  as  a  person  to  whom  Stock  Awards  may  be  granted,  or  in  the
determination  of the  number of shares  which may be  covered  by Stock  Awards
granted to the Director: (i) the Board has delegated its discretionary authority

<PAGE>

over the Plan to a Committee which consists solely of Disinterested  Persons; or
(ii) the Plan otherwise  complies with the requirements of Rule 16b-3. The Board
shall otherwise comply with the requirements of Rule 16b-3. This subsection 5(b)
shall not apply  (i)  prior to the date of the first  registration  of an equity
security of the Company  under  Section 12 of the  Exchange  Act, or (ii) if the
Board or Committee expressly declares that it shall not apply.

               (c) No person shall be eligible for the grant of an Option if, at
the time of grant,  such  person  owns (or is deemed to own  pursuant to Section
424(d) of the Code) stock  possessing  more than ten percent  (10%) of the total
combined  voting  power of all  classes of stock of the Company or of any of its
Affiliates  unless the exercise price of such Option is at least one hundred ten
percent  (110%) of the Fair Market  Value of such stock at the date of grant and
the Option is not  exercisable  after the  expiration of five (5) years from the
date of grant.

6.             OPTION PROVISIONS.

              Each Option shall be in such form and shall contain such terms and
conditions  as the Board  shall deem  appropriate.  The  provisions  of separate
Options  need  not  be  identical,   but  each  Option  shall  include  (through
incorporation of provisions  hereof by reference in the Option or otherwise) the
substance of each of the following provisions:

              (a)       Term.  No Option  shall be  exercisable  after the
expiration  of ten (10)  years from the date it was granted.

              (b) Price. The exercise price of each Incentive Stock Option shall
be not less than one  hundred  percent  (100%) of the Fair  Market  Value of the
stock  subject  to the Option on the date the Option is  granted.  The  exercise
price of each  Nonstatutory  Stock  Option  shall be not less  than  eighty-five
percent (85%) of the Fair Market Value of the stock subject to the Option on the
date the Option is granted.

              (c)  Consideration.  The purchase price of stock acquired pursuant
to an Option shall be paid, to the extent  permitted by applicable  statutes and
regulations,  either (i) in cash at the time the option is exercised, or (ii) at
the discretion of the Board or the Committee, either at the time of the grant or
exercise of the Option,  (A) by delivery to the Company of other common stock of
the Company, (B) according to a deferred payment or other arrangement (which may
include,  without  limiting the  generality of the  foregoing,  the use of other
common stock of the Company) with the person to whom the Option is granted or to
whom the Option is transferred  pursuant to subsection 6(d), or (C) in any other
form of legal consideration that may be acceptable to the Board.

      In the case of any deferred payment arrangement, interest shall be payable
at least annually and shall be charged at the minimum rate of interest necessary
to avoid the treatment as interest, under any applicable provisions of the Code,
of any  amounts  other than  amounts  stated to be interest  under the  deferred
payment arrangement.

               (d)  Transferability.  An Option shall not be transferable except
by will or by the laws of descent  and  distribution,  and shall be  exercisable
during the  lifetime  of the  person to 

<PAGE>

whom the Option is granted  only by such person;  provided,  however,  a  
Nonstatutory  Stock  Option may be  transferred pursuant to a qualified domestic
relations order as defined by the Code or Title I of the Employee  Retirement 
Income  Security Act, or the rules  thereunder (a "QDRO"),  and shall be 
exercisable during the lifetime of the person to whom the Option is granted only
by such person or any transferee pursuant to a QDRO.

               (e) Vesting.  The total  number of shares of stock  subject to an
Option may, but need not, be allotted in periodic  installments  (which may, but
need not, be equal).  The Option  Agreement  may provide  that from time to time
during  each of such  installment  periods,  the Option  may become  exercisable
("vest") with respect to some or all of the shares allotted to that period,  and
may be  exercised  with  respect to some or all of the shares  allotted  to such
period  and/or any prior period as to which the Option became vested but was not
fully exercised.  The vesting  provisions of individual  Options may vary but in
each case will provide for vesting of at least twenty percent (20%) of the total
number of shares  subject to the Option per year.  During the  remainder  of the
term of the  Option  (if its  term  extends  beyond  the end of the  installment
periods),  the option  may be  exercised  from time to time with  respect to any
shares then remaining  subject to the Option.  The provisions of this subsection
6(e) are subject to any Option provisions governing the minimum number of shares
as to which an Option may be exercised.

               (f)  Securities  Law  Compliance.  The  Company  may  require any
Optionee,  or any person to whom an Option is transferred under subsection 6(d),
as a condition of  exercising  any such Option,  (1) to give written  assurances
satisfactory  to the Company as to the  Optionee's  knowledge and  experience in
financial  and  business  matters  and/or to employ a  purchaser  representative
reasonably  satisfactory to the Company who is knowledgeable  and experienced in
financial  and business  matters,  and that he or she is capable of  evaluating,
alone or together  with the  purchaser  representative,  the merits and risks of
exercising the Option;  and (2) to give written  assurances  satisfactory to the
Company  stating that such person is acquiring  the stock  subject to the Option
for such  person's own account and not with any present  intention of selling or
otherwise  distributing the stock. These requirements,  and any assurances given
pursuant to such  requirements,  shall be inoperative if (i) the issuance of the
shares  upon  the  exercise  of the  Option  has  been  registered  under a then
currently effective  registration statement under the Securities Act of 1933, as
amended (the  "Securities  Act"),  or (ii) as to any particular  requirement,  a
determination  is made by counsel for the Company that such requirement need not
be met in the circumstances under the then applicable securities laws.

                (g)  Termination of Employment or  Relationship as a Director or
Consultant.  In the  event  an  Optionee's  Continuous  Status  as an  Employee,
Director  or  Consultant  terminates  (other than upon the  Optionee's  death or
Disability),  the Optionee may exercise his or her Option,  but only within such
period of time as is  determined  by the Board  (which  period shall not be less
than thirty (30) days from the date of such termination), and only to the extent
that the Optionee was entitled to exercise it at the date of termination (but in
no event  later than the  expiration  of the term of such Option as set forth in
the Option  Agreement).  If, at the date of  termination,  the  Optionee  is not
entitled  to  exercise  his or her  entire  Option,  the  shares  covered by the
unexercisable  portion  of the  Option  shall  revert  to the  Plan.  If,  after
termination,  the 

<PAGE>

Optionee  does not exercise his or her Option  within the time specified in the 
Option  Agreement,  the Option shall terminate,  and the shares covered by such 
Option shall revert to the Plan.

                (h)   Disability  of  Optionee.   In  the  event  an  Optionee's
Continuous Status as an Employee,  Director or Consultant terminates as a result
of the Optionee's  Disability,  the Optionee may exercise his or her Option, but
only within  such period of time as is  determined  by the Board  (which  period
shall not be less than six (6) months  from the date of such  termination),  and
only to the extent that the  Optionee was entitled to exercise it at the date of
such  termination (but in no event later than the expiration of the term of such
Option as set forth in the Option  Agreement).  If, at the date of  termination,
the Optionee is not entitled to exercise  his or her entire  Option,  the shares
covered by the unexercisable portion of the Option shall revert to the Plan. If,
after  termination,  the Optionee does not exercise his or her Option within the
time specified  herein,  the Option shall  terminate,  and the shares covered by
such Option shall revert to the Plan.

               (i) Death of Optionee.  In the event of the death of an Optionee,
the Option may be exercised,  at any time within such period as is determined by
the Board (which period shall not be less than six (6) months following the date
of death) by the  Optionee's  estate or by a person  who  acquired  the right to
exercise  the  Option by  bequest  or  inheritance,  and only to the  extent the
Optionee  was  entitled to  exercise  the Option at the date of death (but in no
event later than the  expiration  of the term of such Option as set forth in the
Option  Agreement).  If, at the time of death,  the Optionee was not entitled to
exercise  his or her  entire  Option,  the shares  covered by the  unexercisable
portion of the Option shall revert to the Plan. If, after death,  the Optionee's
estate or a person who  acquired  the right to exercise the Option by bequest or
inheritance does not exercise the Option within the time specified  herein,  the
Option shall  terminate,  and the shares  covered by such Option shall revert to
the Plan.

                (j)  Withholding.  To the  extent  provided  by the  terms of an
Option  Agreement,  the  Optionee  may satisfy any  federal,  state or local tax
withholding  obligation  relating  to the  exercise of such Option by any of the
following means or by a combination of such means: (1) tendering a cash payment;
(2)  authorizing  the Company to  withhold  shares from the shares of the common
stock  otherwise  issuable to the participant as a result of the exercise of the
Option;  or (3) delivering to the Company owned and  unencumbered  shares of the
common stock of the Company.

                (k) Re-Load  Options.  Without in any way limiting the authority
of the Board or  Committee  to make or not to make grants of Options  hereunder,
the Board or  Committee  shall have the  authority  (but not an  obligation)  to
include as part of any Option Agreement a provision  entitling the Optionee to a
further  Option (a "Re-Load  Option") in the event the  Optionee  exercises  the
Option evidenced by the Option  Agreement,  in whole or in part, by surrendering
other  shares of  Common  Stock in  accordance  with this Plan and the terms and
conditions of the Option  Agreement.  Any such Re-Load Option (i) shall be for a
number of shares equal to the number of shares surrendered as part or all of the
exercise price of such Option;  (ii) shall have an expiration  date which is the
same as the  expiration  date of the Option the  exercise  of which gave rise to
such Re-Load  

<PAGE>

Option;  and (iii) shall have an exercise  price which is equal to one hundred
percent (100%) of the Fair Market Value of the Common Stock subject to the 
Re-Load Option on the date of exercise of the original  Option or, in the case 
of a Re-Load Option which is granted to a ten percent (10%) shareholder (as
described in subparagraph  5(c)), shall have an exercise price which is equal to
one hundred ten percent  (110%) of the Fair Market Value of the stock subject to
the Re-Load Option on the date of exercise of the original Option.

      Any such Re-Load Option may be an Incentive Stock Option or a Nonstatutory
Stock  Option,  as the Board or Committee may designate at the time of the grant
of the original Option,  provided,  however, that the designation of any Re-Load
Option as an Incentive Stock Option shall be subject to the one hundred thousand
dollars  ($100,000)  annual  limitation  on  exercisability  of Incentive  Stock
Options  described in subsection  11(e) of the Plan and in Section 422(d) of the
Code.  There shall be no Re-Load Options on a Re-Load  Option.  Any such Re-Load
Option  shall  be  subject  to  the  availability  of  sufficient  shares  under
subparagraph 4(a) and shall be subject to such other terms and conditions as the
Board or Committee may determine.

7.              TERMS OF STOCK BONUSES AND PURCHASES OF RESTRICTED STOCK.

                Each stock bonus or restricted stock purchase agreement shall be
in such form and shall  contain  such terms and  conditions  as the Board or the
Committee  shall deem  appropriate.  The terms and  conditions of stock bonus or
restricted stock purchase agreements may change from time to time, and the terms
and  conditions of separate  agreements  need not be  identical,  but each stock
bonus  or  restricted   stock   purchase   agreement   shall  include   (through
incorporation  of provisions  hereof by reference in the agreement or otherwise)
the substance of each of the following provisions as appropriate:

                (a) Purchase Price. The purchase price under each stock purchase
agreement  shall be such amount as the Board or Committee  shall  determine  and
designate in such agreement (which purchase price shall in any event be not less
than eighty-five percent (85%) of the Fair Market Value of the stock on the date
such award is made),  provided  that the  purchase  price  shall be one  hundred
percent  (100%) of the fair market  value of the stock on the date such award is
made, in the case of any person who owns stock  possessing more than ten percent
(10%)  of the  total  combined  voting  power  of all  classes  of  stock of the
Applicant.  Notwithstanding  the  foregoing,  the  Board  or the  Committee  may
determine that eligible  participants  in the Plan may be awarded stock pursuant
to a stock bonus agreement in consideration  for past services actually rendered
to the Company or for its benefit.

                (b) Transferability. No rights under a stock bonus or restricted
stock purchase agreement shall be transferable  except by will or by the laws of
descent and distribution.

                (c) Consideration. The purchase price of stock acquired pursuant
to a stock purchase  agreement shall be paid either:  (i) in cash at the time of
purchase;  (ii) at the discretion of the Board or the Committee,  according to a
deferred payment or other arrangement with the person to whom the stock is sold;
or (iii) in any other form of legal  consideration that may be acceptable to the
Board or the Committee in their discretion.  Notwithstanding the foregoing,  the
Board or the Committee to which  administration  of the Plan has been  delegated
may award stock pursuant to a stock bonus  agreement in  consideration  for past
services actually rendered to the Company or for its benefit.

<PAGE>

               (d) Vesting.  Shares of stock sold or awarded under the Plan may,
but need not,  be  subject  to a  repurchase  option in favor of the  Company in
accordance  with  a  vesting  schedule  to be  determined  by the  Board  or the
Committee.

               (e)  Termination of Employment or  Relationship  as a Director or
Consultant.  In the event a  Participant's  Continuous  Status  as an  Employee,
Director or  Consultant  terminates,  the Company may  repurchase  or  otherwise
reacquire  any or all of the shares of stock held by that person  which have not
vested as of the date of  termination  under  the  terms of the  stock  bonus or
restricted stock purchase agreement between the Company and such person.

8.             CANCELLATION AND RE-GRANT OF OPTIONS.

               The Board or the Committee shall have the authority to effect, at
any time and from time to time,  with the  consent  of the  affected  holders of
Options, (i) the repricing of any outstanding Options under the Plan and/or (ii)
the  cancellation  of any  outstanding  Options  under the Plan and the grant in
substitution  therefor  of new  Options  under  the  Plan  covering  the same or
different numbers of shares of stock, but having an exercise price per share not
less than  eighty-five  percent  (85%) of the Fair  Market  Value  (one  hundred
percent (100%) of the Fair Market Value in the case of an Option or, in the case
of a ten percent (10%) shareholder (as described in subparagraph 5(c)), not less
than one hundred ten percent (110%) of the Fair Market Value) per share of stock
on the new grant date.

9.              COVENANTS OF THE COMPANY.

                (a) During the terms of the Stock Awards, the Company shall keep
available  at all times the number of shares of stock  required to satisfy  such
Stock Awards up to the number of shares of stock authorized under the Plan.

                (b) The  Company  shall  seek to  obtain  from  each  regulatory
commission or agency having  jurisdiction over the Plan such authority as may be
required  to issue and sell shares of stock  under the Stock  Awards;  provided,
however,  that this undertaking  shall not require the Company to register under
the  Securities  Act either  the Plan,  any Stock  Award or any stock  issued or
issuable  pursuant to any such Stock Award.  If, after reasonable  efforts,  the
Company is unable to obtain from any such  regulatory  commission  or agency the
authority  which counsel for the Company deems necessary for the lawful issuance
and sale of stock  under  the  Plan,  the  Company  shall be  relieved  from any
liability for failure to issue and sell stock under such Stock Awards unless and
until such authority is obtained.

10.             USE OF PROCEEDS FROM STOCK.

                Proceeds  from the sale of stock  pursuant to Stock Awards shall
constitute general funds of the Company.

11.             MISCELLANEOUS.

<PAGE>

                (a) The Board  shall  have the power to  accelerate  the time at
which a Stock  Award may first be  exercised  or the time  during  which a Stock
Award or any part thereof will vest, notwithstanding the provisions in the Stock
Award  stating  the time at which it may first be  exercised  or the time during
which it will vest.

                (b)  Neither  an  Optionee  nor any  person to whom an Option is
transferred  under  subsection  6(d)  shall be deemed to be the holder of, or to
have any of the rights of a holder with  respect to, any shares  subject to such
Option unless and until such person has satisfied all  requirements for exercise
of the Option pursuant to its terms.

                (c) Throughout  the term of any Option  granted  pursuant to the
Plan, the Company shall deliver to the holder of such Option, not later than one
hundred twenty (120) days after the close of each of the Company's  fiscal years
during the Option term, a balance sheet and an income statement. This subsection
shall not apply when an issuance  is limited to key  employees  whose  duties in
connection with the Company assure them access to equivalent information.

                (d)  Nothing  in the Plan or any  instrument  executed  or Stock
Award  granted  pursuant  thereto  shall  confer  upon any  Employee,  Director,
Consultant,  Optionee,  or other holder of Stock Awards any right to continue in
the employ of the Company or any Affiliate (or to continue  acting as a Director
or  Consultant)  or shall  affect the right of the Company or any  Affiliate  to
terminate the employment of any Employee,  or the  relationship as a Director or
Consultant of any Director or Consultant with or without cause.

                (e)  To  the  extent  that  the  aggregate   Fair  Market  Value
(determined at the time of grant) of stock with respect to which Incentive Stock
Options  granted after 1986 are  exercisable  for the first time by any Optionee
during any  calendar  year  under all plans of the  Company  and its  Affiliates
exceeds one hundred thousand dollars ($100,000), the Options or portions thereof
which  exceed  such limit  (according  to the order in which they were  granted)
shall be treated as Nonstatutory Stock Options.

12.       ADJUSTMENTS UPON CHANGES IN STOCK.

                (a) If any change is made in the stock  subject to the Plan,  or
subject  to any Stock  Award  (through  merger,  consolidation,  reorganization,
recapitalization,  stock dividend,  dividend in property other than cash,  stock
split,  liquidating dividend,  combination of shares, exchange of shares, change
in corporate structure or otherwise), the Plan and outstanding Stock Awards will
be appropriately  adjusted in the class(es) and maximum number of shares subject
to the Plan and the  class(es) and number of shares and price per share of stock
subject to outstanding Stock Awards.

                (b) In the event of: (1) a merger or  consolidation in which the
Company is not the surviving  corporation;  or (2) a reverse merger in which the
Company is the  surviving  corporation  but the shares of the  Company's  common
stock  outstanding  immediately  preceding the merger are converted by virtue of
the merger  into other  property,  whether  in the form of  securities,  cash or
otherwise, then, at the sole discretion of the Board and to the extent permitted
by applicable law: (i) any surviving  corporation  shall assume any Stock Awards
outstanding  

<PAGE>

under the Plan or shall  substitute  similar Stock Awards for those
outstanding  under the Plan or (ii) such Stock  Awards  shall  continue  in full
force and effect.  In the event any surviving  corporation  refuses to assume or
continue  such  Stock  Awards,  or  to  substitute   similar  awards  for  those
outstanding  under  the  Plan,  the  Stock  Awards  shall be  terminated  if not
exercised  prior to such event.  In the event of a dissolution or liquidation of
the Company,  any Stock Awards outstanding under the Plan shall terminate if not
exercised prior to such event.

13.             AMENDMENT OF THE PLAN.

                (a) The Board at any time,  and from time to time, may amend the
Plan.  However,  except as provided in Section 13 relating to  adjustments  upon
changes  in stock,  no  amendment  shall be  effective  unless  approved  by the
shareholders  of the  Company  within  twelve  (12)  months  before or after the
adoption of the amendment, where the amendment will:

                          (i)      Increase  the number of shares  reserved  for
Stock  Awards  under the Plan;

                          (ii)     Modify the  requirements  as to eligibility
for  participation  in the Plan to the extent such modification  requires
shareholder approval in order for the Plan to satisfy the requirements of
Section 422 of the Code; or

                         (iii)     Modify  the  Plan  in any  other  way if
such  modification  requires shareholder  approval  in order  for the Plan to
satisfy  the  requirements  of Section 422 of the Code or to comply with the
requirements of Rule 16b-3.

                (b) It is  expressly  contemplated  that the Board may amend the
Plan in any respect the Board deems necessary or advisable to provide  Optionees
with the maximum benefits provided or to be provided under the provisions of the
Code and the  regulations  promulgated  thereunder  relating to Incentive  Stock
Options and/or to bring the Plan and/or Incentive Stock Options granted under it
into compliance therewith.

                (c) Rights and obligations  under any Stock Award granted before
amendment  of the Plan shall not be altered or impaired by any  amendment of the
Plan unless (i) the Company requests the consent of the person to whom the Stock
Award was granted and (ii) such person consents in writing.

14.             TERMINATION OR SUSPENSION OF THE PLAN.

                (a) The Board may  suspend  or  terminate  the Plan at any time.
Unless  sooner  terminated,  the Plan shall  terminate on November 21, 2003.  No
Stock Awards may be granted  under the Plan while the Plan is suspended or after
it is terminated.

                (b) Rights and  obligations  under any Stock Award granted while
the Plan is in  effect  shall  not be  altered  or  impaired  by  suspension  or
termination of the Plan, except with the consent of the person to whom the Stock
Award was granted.

<PAGE>

15.             EFFECTIVE DATE OF PLAN.

               The Plan shall become  effective as determined by the Board,  but
no Stock Awards granted under the Plan shall be exercisable unless and until the
Plan has been approved by the shareholders of the Company,  and, if required, an
appropriate  permit has been issued by the  Commissioner  of Corporations of the
State of California.



IT IS  UNLAWFUL  TO  CONSUMMATE  A SALE OR  TRANSFER  OF THIS  SECURITY,  OR ANY
INTEREST THEREIN,  OR TO RECEIVE ANY CONSIDERATION  THEREFOR,  WITHOUT THE PRIOR
WRITTEN CONSENT OF THE  COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA,
EXCEPT AS PERMITTED IN THE COMMISSIONER'S RULES.

                             INCENTIVE STOCK OPTION

_________________________, Optionee:

         Alanex  Corporation  (the  "Company"),  pursuant to its 1993 Stock Plan
(the "Plan") has this day granted to you, the optionee named above, an option to
purchase shares of the common stock of the Company ("Common Stock"). This option
is  intended to qualify as an  "incentive  stock  option"  within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code").

         The grant  hereunder is in connection  with and in  furtherance  of the
Company's compensatory benefit plan for participation of the Company's employees
(including officers) directors or consultants and is intended to comply with the
provisions of Rule 701  promulgated by the  Securities  and Exchange  Commission
under the Securities Act of 1933, as amended (the "Act").

         The details of your option are as follows:


                  1. The total number of shares of Common Stock  subject to this
option  is  ____________________   (__________).   Subject  to  the  limitations
contained  herein,  this  option  shall  be  exercisable  with  respect  to each
installment  shown  below on or after  the date of  vesting  applicable  to such
installment,  as follows [THE TERMS OF INDIVIDUAL  OPTIONS WILL VARY BUT WILL IN
ANY CASE PROVIDE FOR VESTING OF AT LEAST 20% PER YEAR]:


    Number of Shares (Installment)          Date of Earliest Exercise (Vesting)

<PAGE>

                  2.        (a)     The  exercise  price of this option is
___________  ($___________)  per share, being not less than the Fair Market
Value of the Common Stock on the date of grant of this option.

                            (b)     Payment  of the  exercise  price per  share
 is due in full in cash  (including check)  upon  exercise of all or any part of
each  installment  which has become exercisable by you. Notwithstanding the
foregoing,  this option may be exercised pursuant to a program developed under
Regulation T as promulgated by the Federal Reserve  Board  which  results in the
receipt of cash (or check) by the Company prior to the issuance of Common Stock.

                  3. The  minimum  number of shares  with  respect to which this
option may be exercised at any one time is one hundred  (100),  except (a) as to
an installment  subject to exercise,  as set forth in paragraph 1, which amounts
to fewer than one hundred  (100)  shares,  in which case,  as to the exercise of
that installment,  the number of shares in such installment shall be the minimum
number of shares, and (b) with respect to the final exercise of this option this
minimum shall not apply. In no event may this option be exercised for any number
of shares which would require the issuance of anything other than whole shares.

                  4. Notwithstanding  anything to the contrary contained herein,
this option may not be exercised  unless the shares  issuable  upon  exercise of
this option are then registered under the Act or, if such shares are not then so
registered,  the Company has determined that such exercise and issuance would be
exempt from the registration requirements of the Act.

                  5. The term of this option  commences  on the date hereof and,
unless  sooner  terminated  as set  forth  below or in the Plan,  terminates  on
____________,  2003  (which  date  shall be no more than ten (10) years from the
date this option is  granted).  In no event may this option be  exercised  on or
after the date on which it terminates.  This option shall terminate prior to the
expiration  of its term as follows:  three (3) months after the  termination  of
your  employment  with the Company or an Affiliate of the Company (as defined in
the Plan) for any reason or for no reason unless:

                             (a)       such  termination of employment is due to
your permanent and total  disability (within the meaning of Section 422(c)(6) of
 the Code), in which event the option shall terminate on the earlier of the
termination date set forth above or twelve (12) months following such
termination of employment; or

                             (b)       such  termination  of  employment  is due
to your  death,  in which  event the option  shall  terminate  on the earlier of
the  termination  date set forth above or twelve (12) months after your death;
or

                             (c)       during any part of such three (3) month
period the option is not  exercisable solely  because of the condition set forth
in paragraph 4 above,  in which event the option shall not  terminate  until
the earlier of the  termination  date set forth above or until it shall have
been  exercisable for an aggregate  period of three (3) months after the
termination of employment; or

<PAGE>

                            (d)       exercise  of the option  within  three (3)
months  after  termination  of your employment with the Company or with an
affiliate would result in liability under section 16(b) of the  Securities
Exchange Act of 1934, in which case the option will terminate on the earlier of
(i) the termination date set forth above,  (ii) the tenth  (10th) day after the
last date upon which  exercise  would  result in such  liability or (iii) six
(6) months and ten (10) days after the  termination of your employment with the
Company or an affiliate.

                  However, this option may be exercised following termination of
employment  only as to that number of shares as to which it was  exercisable  on
the date of  termination  of employment  under the  provisions of paragraph 1 of
this option.

                  6.       (a)     This option may be exercised,  to the extent
specified above,  by delivering a notice of exercise (in a form designated by
the Company) together  with the exercise  price to the  Secretary of the
Company,  or to such other  person as the Company  may  designate,  during
regular  business  hours, together with such additional documents as the Company
may then require.

                           (b)       By exercising this option you agree that:

                                    (i)      the  Company may require  you to
enter an  arrangement  providing  for the  payment by you to the  Company  of
any tax  withholding  obligation  of the Company  arising by reason of (1) the
exercise of this option;  (2) the lapse of any  substantial  risk of forfeiture
to which the shares are subject at the time of exercise; or (3) the disposition
of shares acquired upon such exercise;

                                    (ii)     you will  notify  the  Company  in
writing  within  fifteen  (15) days after  the date of any  disposition  of any
of the  shares of the  Common  Stock issued upon  exercise of this option that
occurs  within two (2) years after the date of this  option  grant or within one
(1) year  after such  shares of Common Stock are transferred upon exercise of
this option; and

                                     (iii)     the Company (or a
representative  of the  underwriters)  may, in  connection with the first
underwritten  registration  of the offering of any securities of the Company
under the Act,  require that you not sell or otherwise  transfer or
dispose of any shares of Common Stock or other  securities of the Company during
such  period  (not to exceed  one  hundred  eighty  (180)  days)  following  the
effective  date (the  "Effective  Date") of the  registration  statement  of the
Company  filed  under  the  Act as  may  be  requested  by  the  Company  or the
representative of the  underwriters;  provided,  however,  that such restriction
shall apply only if, on the Effective  Date,  you are an officer,  director,  or
owner  of more  than  one  percent  (1%) of the  outstanding  securities  of the
Company.  For purposes of this  restriction you will be deemed to own securities
which (i) are owned directly or indirectly by you, including securities held for
your benefit by nominees,  custodians, brokers or pledgees; (ii) may be acquired
by you within sixty (60) days of the Effective Date; (iii) are owned directly or
indirectly,  by or for your brothers or sisters (whether by whole or half blood)
spouse,  ancestors  and  lineal  descendants;  or (iv) are  owned,  directly  or
indirectly, by or for a corporation,  partnership,  estate or trust of which you
are a  shareholder,  partner  or  beneficiary,  but only to the  extent  of your
proportionate

              exercised:                                     ___________________

              Certificates to be

              Cash payment delivered
              herewith:                                      $__________________


      By this exercise,  I agree (i) to provide such additional documents as you
may require  pursuant  to the terms of the 1993 Stock Plan,  (ii) to provide for
the payment by me to you (in the manner  designated by you) of your  withholding
obligation,  if any, relating to the exercise of this option,  and (iii) if this
exercise  relates to an incentive stock option,  to notify you in writing within
fifteen  (15) days  after the date of any  disposition  of any  shares of Common
Stock issued upon exercise of this option that occurs within two (2) years after
the date of grant of this  option or within one (1) year  after  such  shares of
Common Stock are issued upon exercise of this option.

      I hereby  make  the  following  certifications  and  representations  with
respect to the number of shares of Common Stock of the Company listed above (the
"Shares"),  which are being  acquired by me for my own account upon  exercise of
the Option as set forth above:

<PAGE>

      I  acknowledge  that  the  Shares  have  not  been  registered  under  the
Securities  Act of 1933,  as amended (the "Act"),  and are deemed to  constitute
"restricted  securities" under Rule 701 and "control  securities" under Rule 144
promulgated under the Act. I warrant and represent to the Company that I have no
present  intention of distributing  or selling said Shares,  except as permitted
under the Act and any applicable state securities laws.

      I further  acknowledge that I will not be able to resell the Shares for at
least ninety (90) days after the stock of the Company  becomes  publicly  traded
(i.e.,  subject  to the  reporting  requirements  of  Section 13 or 15(d) of the
Securities  Exchange  Act of 1934)  under  Rule 701 and  that  more  restrictive
conditions apply to affiliates of the Company under Rule 144.

      I further acknowledge that all certificates representing any of the Shares
subject to the provisions of the Option shall have endorsed thereon  appropriate
legends reflecting the foregoing limitations,  as well as any legends reflecting
restrictions pursuant to the Company's Articles of Incorporation,  Bylaws and/or
applicable securities laws.

      I further agree that, if required by the Company (or a  representative  of
the underwriters) in connection with the first underwritten  registration of the
offering  of any  securities  of the  Company  under the Act, I will not sell or
otherwise  transfer or dispose of any shares of Common Stock or other securities
of the Company  during such period (not to exceed one hundred eighty (180) days)
following the effective date of the registration  statement of the Company filed
under the Act (the  "Effective  Date") as may be requested by the Company or the
representative of the  underwriters;  provided,  however,  that such restriction
shall apply only if, on the Effective  Date,  you are an officer,  director,  or
owner  of more  than  one  percent  (1%) of the  outstanding  securities  of the
Company.  For purposes of this  restriction  I will be deemed to own  securities
that (i) are owned directly or indirectly by me,  including  securities held for
my benefit by nominees, custodians, brokers or pledgees; (ii) may be acquired by
me within sixty (60) days of the  Effective  Date;  (iii) are owned  directly or
indirectly,  by or for my brothers or sisters  (whether by whole or half blood),
spouse,  ancestors  and  lineal  descendants;  or (iv) are  owned,  directly  or
indirectly, by or for a corporation,  partnership, estate or trust of which I am
a  shareholder,   partner  or  beneficiary,   but  only  to  the  extent  of  my
proportionate interest therein as a shareholder, partner or beneficiary thereof.
I further  agree that the Company  may impose  stop-transfer  instructions  with
respect to  securities  subject to the foregoing  restrictions  until the end of
such period.

                                              Very truly yours,

                            NONSTATUTORY STOCK OPTION



________________, Optionee:

         Alanex  Corporation  (the  "Company"),  pursuant to its 1993 Stock Plan
(the "Plan") has this day granted to you, the optionee named above, an option to
purchase shares of the common stock of the Company ("Common Stock"). This option
is not  intended  to  qualify  and will not be treated  as an  "incentive  stock
option" within the meaning of Section 422 of the Internal  Revenue Code of 1986,
as amended (the "Code").

         The grant  hereunder is in connection  with and in  furtherance  of the
Company's compensatory benefit plan for participation of the Company's employees
(including  officers),  directors or consultants  and is intended to comply with
the provisions of Rule 701 promulgated by the Securities and Exchange Commission
under the Securities Act of 1933, as amended (the "Act").

         The details of your option are as follows:

                  1. The total number of shares of Common Stock  subject to this
option is ____________. Subject to the limitations contained herein, this option
shall be exercisable  with respect to each  installment  shown below on or after
the date of vesting  applicable  to such  installment,  as follows [THE TERMS OF
INDIVIDUAL  OPTIONS  WILL VARY BUT WILL IN ANY CASE  PROVIDE  FOR  VESTING OF AT
LEAST 20% PER YEAR]:


Number of Shares (Installment)              Date of Earliest Exercise (Vesting)

<PAGE>

                  2.       (a)     The  exercise  price of this  option is
$_______  ($____) per share,  being not less than eighty-five (85%) of the Fair
Market Value of the Common Stock on the date of grant of this option.

                           (b)       Payment  of the  exercise  price per  share
is due in full in cash  (including check)  upon  exercise of all or any part of
each  installment  which has become exercisable by you. Notwithstanding the
foregoing,  this option may be exercised pursuant to a program developed under
Regulation T as promulgated by the Federal Reserve  Board  which  results in the
receipt of cash (or check) by the Company prior to the issuance of Common Stock.

                  3. The  minimum  number of shares  with  respect to which this
option may be exercised at any one time is one hundred  (100),  except (a) as to
an installment  subject to exercise,  as set forth in paragraph 1, which amounts
to fewer than one hundred  (100)  shares,  in which case,  as to the exercise of
that  installment,  the number of such shares in such  installment  shall be the
minimum  number of shares,  and (b) with  respect to the final  exercise of this
option this  minimum  shall not apply.  In no event may this option be exercised
for any number of shares which would require the issuance of anything other than
whole shares.

                  4. Notwithstanding  anything to the contrary contained herein,
this option may not be exercised  unless the shares  issuable  upon  exercise of
this option are then registered under the Act or, if such shares are not then so
registered,  the Company has determined that such exercise and issuance would be
exempt from the registration requirements of the Act.

                  5. The term of this option  commences  on the date hereof and,
unless  sooner  terminated  as set  forth  below or in the Plan,  terminates  on
____________,  2003  (which  date  shall be no more than ten (10) years from the
date this option is  granted).  In no event may this option be  exercised  on or
after the date on which it terminates.  This option shall terminate prior to the
expiration of its term as follows:  six (6) months after the termination of your
employment  with the Company or an  Affiliate  of the Company (as defined in the
Plan) for any reason or for no reason unless:

                           (a)       such  termination of employment is due to
your permanent and total  disability (within the meaning of Section 422(c)(6) of
the Code), in which event the option shall terminate on the earlier of the
termination date set forth above or twelve (12) months following such
termination of employment;

                           (b)       such  termination  of  employment  is due
to your  death,  in which  event the option  shall  terminate  on the earlier of
the  termination  date set forth above or twelve (12) months after your death;
or

                           (c)       during any part of such six (6) month
period  the  option is not  exercisable solely  because of the condition set
forth in paragraph 4 above,  in which event the option shall not  terminate
until the earlier of the  termination  date set forth above or until it shall
have been  exercisable for an aggregate  period of six (6) months after the
termination of employment; or

<PAGE>

                           (d)       exercise  of the  option  within  six (6)
months  after  termination  of your employment with the Company or with an
affiliate would result in liability under section 16(b) of the  Securities
Exchange Act of 1934, in which case the option will terminate on the earlier of
(i) the termination date set forth above,  (ii) the tenth  (10th) day after the
last date upon which  exercise  would  result in such  liability or (iii) six
(6) months and ten (10) days after the  termination of your employment with the
Company or an affiliate.

                  However, this option may be exercised following termination of
employment  only as to that number of shares as to which it was  exercisable  on
the date of  termination  of employment  under the  provisions of paragraph 1 of
this option.

                  6. (a) This option may be exercised,  to the extent  specified
above,  by delivering a notice of exercise (in a form designated by the Company)
together  with the exercise  price to the  Secretary of the Company,  or to such
other  person as the Company  may  designate,  during  regular  business  hours,
together with such additional documents as the Company may then require.

                            (b)       By exercising this option you agree that:

                                     (i)      the  Company may require  you to
enter an  arrangement  providing  for the cash payment by you to the Company of
any tax withholding  obligation of the
Company arising by reason of: (1) the exercise of this option;  (2) the lapse of
any  substantial  risk of forfeiture to which the shares are subject at the time
of exercise; or (3) the disposition of shares acquired upon such exercise; and

                                     (ii)     the Company (or a representative
of the  underwriters)  may, in connection with the first  underwritten
registration  of the offering of any  securities of the Company  under  the Act,
require  that you not sell or  otherwise  transfer  or dispose of any shares of
Common Stock or other  securities of the Company during such  period  (not to
exceed  one  hundred  eighty  (180)  days)  following  the effective  date (the
"Effective  Date") of the  registration  statement  of the Company  filed  under
the  Act as  may  be  requested  by  the  Company  or the representative of the
underwriters;  provided,  however,  that such restriction shall apply only if,
on the Effective  Date,  you are an officer,  director,  or owner  of more  than
one  percent  (1%) of the  outstanding  securities  of the Company.  For
purposes of this  restriction you will be deemed to own securities which (i) are
owned directly or indirectly by you, including securities held for your benefit

      By this exercise,  I agree (i) to provide such additional documents as you
may require  pursuant  to the terms of the 1993 Stock Plan,  (ii) to provide for
the payment by me to you (in the manner  designated by you) of your  withholding
obligation,  if any, relating to the exercise of this option,  and (iii) if this

"restricted  securities" under Rule 701 and "control  securities" under Rule 144
promulgated under the Act. I warrant and represent to the Company that I have no
present  intention of distributing  or selling said Shares,  except as permitted
under the Act and any applicable state securities laws.

      I further  acknowledge that I will not be able to resell the Shares for at
least ninety (90) days after the stock of the Company  becomes  publicly  traded
(i.e.,  subject  to the  reporting  requirements  of  Section 13 or 15(d) of the
Securities  Exchange  Act of 1934)  under  Rule 701 and  that  more  restrictive
conditions apply to affiliates of the Company under Rule 144.

restrictions pursuant to the Company's Articles of Incorporation,  Bylaws and/or
applicable securities laws.

      I further agree that, if required by the Company (or a  representative  of
the underwriters) in connection with the first underwritten  registration of the
offering  of any  securities  of the  Company  under the Act, I will not sell or
otherwise  transfer or dispose of any shares of Common Stock or other securities
of the Company  during such period (not to exceed one hundred eighty (180) days)
following the effective date of the registration  statement of the Company filed
under the Act (the  "Effective  Date") as may be requested by the Company or the
representative of the  underwriters;  provided,  however,  that such restriction
shall apply only if, on the Effective  Date,  you are an officer,  director,  or
owner  of more  than  one  percent  (1%) of the  outstanding  securities  of the
Company.  For purposes of this  restriction  I will be deemed to own  securities
that (i) are owned directly or indirectly by me,  including  securities held for
my benefit by nominees, custodians, brokers or pledgees; (ii) may be acquired by
me within sixty (60) days of the  Effective  Date;  (iii) are owned  directly or
indirectly,  by or for my brothers or sisters  (whether by whole or half blood),
spouse,  ancestors  and  lineal  descendants;  or (iv) are  owned,  directly  or
indirectly, by or for a corporation,  partnership, estate or trust of which I am
a  shareholder,   partner  or  beneficiary,   but  only  to  the  extent  of  my
proportionate interest therein as a shareholder, partner or beneficiary thereof.
I further  agree that the Company  may impose  stop-transfer  instructions  with
respect to  securities  subject to the foregoing  restrictions  until the end of
such period.

3.         ADMINISTRATION.

           (a)        The Plan  shall be  administered  by the Board  unless and
until  the  Board  delegates  administration  to a  Committee,  as  provided  in
subsection 3(c).

           (b)       The Board  shall  have the power,  subject  to,  and
within  the  limitations  of, the express provisions of the Plan:

                     (1)       To determine  from time to time which of the
persons  eligible  under the Plan shall be granted Stock  Awards;  when and how
each Stock Award shall be granted; whether a Stock Award will be an Incentive
Stock Option,  a Nonstatutory  Stock Option, a stock bonus, a right to purchase
restricted stock, or a combination of the  foregoing;  the  provisions of each
Stock Award granted  (which need not be identical),  including  the time or
times when a person  shall be  permitted  to receive stock  pursuant to a Stock
Award;  and the number of shares with respect to which a Stock Award shall be
granted to each such person.

                     (2)       To construe and interpret  the Plan and Stock
Awards  granted under it, and to establish,  amend and revoke rules and
regulations for its  administration.  The Board,  in the  exercise  of this
power,  may  correct  any defect,  omission or inconsistency  in the Plan or in
any Stock Award  Agreement,  in a manner and to the  extent  it shall  deem
necessary  or  expedient  to make  the  Plan  fully effective.

                     (3)       To amend the Plan or a Stock Award as provided in
Section 13.

                     (4)       Generally,  to  exercise  such  powers and to
perform  such acts as the Board deems  necessary or expedient which are not
inconsistent  with the terms of the Plan to promote the best interests of the
Company.

           (c)        The Board  may  delegate  administration  of the Plan to a
committee  of the  Board  composed  of not  fewer  than  two  (2)  members  (the
"Committee"), all of the members of which Committee may be, in the discretion of
the Board, Non-Employee Directors and/or Outside Directors. If administration is
delegated to a Committee,  the  Committee  shall have,  in  connection  with the
administration  of the Plan,  the  powers  theretofore  possessed  by the Board,
including  the power to delegate to a  subcommittee  of two (2) or more  Outside
Directors  any of the  administrative  powers the  Committee  is  authorized  to

time by the Board. The Board may abolish the Committee at any time and revest in
the  

<PAGE>

Board the  administration  of the Plan.  Notwithstanding  anything  in this
Section 3 to the  contrary,  at any time the Board or the Committee may delegate
to a committee of one or more members of the Board the  authority to grant Stock
Awards to  eligible  persons  who (1) are not then  subject to Section 16 of the
Exchange  Act and/or (2) are either (i) not then Covered  Employees  and are not
expected to be Covered  Employees at the time of recognition of income resulting
from such Stock  Award,  or (ii) not  persons  with  respect to whom the Company
wishes to comply with Section 162(m) of the Code.

                  (d) Any  requirement  that an  administrator  of the Plan be a
Non-Employee  Director  shall  not  apply  (i)  prior to the  date of the  first
registration  of an equity  security  of the  Company  under  Section  12 of the
Exchange Act, or (ii) if the Board or the Committee expressly declares that such
requirement  shall not apply. Any  Non-Employee  Director shall otherwise comply
with the requirements of Rule 16b-3.

4.         SHARES SUBJECT TO THE PLAN.

           (a)         Subject  to the  provisions  of Section  12  relating  to
adjustments  upon  changes in stock,  the stock that may be issued  pursuant  to
Stock  Awards  granted  under the Plan  shall not exceed in the  aggregate  five
hundred  thousand  (500,000)  shares of the Company's common stock. If any Stock
Award granted under the Plan shall for any reason expire or otherwise terminate,
in whole or in part,  without  having  been  exercised  in full,  the  stock not
acquired  under such Stock Award shall revert to and again become  available for
issuance under the Plan.

           (b)        The stock subject to the Plan may be unissued  shares or
reacquired  shares,  bought on the market or otherwise.

5.        ELIGIBILITY.

           (a)        Incentive  Stock Options may be granted only to Employees.
Stock  Awards  other  than  Incentive  Stock  Options  may be  granted  only  to
Employees,  Directors or Consultants.  Notwithstanding  the foregoing,  no Stock
Awards  shall be granted to a Director  (including a Director who is an Employee
or a  Consultant)  between (i) the date of the first  registration  of an equity
security of the Company  under  Section 12 of the Exchange  Act, and (ii) August
15,  1996 (or such later  date as the  amendments  to Rule 16b-3  adopted by the
Securities  and  Exchange  Commission  pursuant to Release No.  34-37260  become
effective  as to the  Company),  unless  such  Director  is  expressly  declared
eligible to participate in the Plan by action of the Board or the Committee.

           (b)        No person  shall be eligible for the grant of an Incentive
Stock  Option if, at the time of grant,  such  person  owns (or is deemed to own
pursuant to Section 424(d) of the Code) stock  possessing  more than ten percent
(10%) of the total combined  voting power of all classes of stock of the Company
or of any of its Affiliates unless the exercise price of such Option is at least
one  hundred ten  percent  (110%) of the Fair Market  Value of such stock at the
date of grant and the Option is not exercisable after the expiration of five (5)
years from the date of grant.  Prior to the date of the first registration of an
equity  security  of the  Company  under  

<PAGE>

Section 12 of the  Exchange  Act,  the provisions  of  this  subsection  5(b)  
shall  also  apply  to  the  grant  of a Nonstatutory  Stock Option made to a 
ten percent (10%)  stockholder as described in the preceding sentence.

           (c)         Subject to the  provisions  of Section  12  (relating  to
adjustments  upon  changes in stock) no person  shall be  eligible to be granted
Options covering more than three hundred seventy-five  thousand (375,000) shares
of the Company's  common stock in any calendar year.  This subsection 5(c) shall
not apply prior to the date of the first  registration  of an equity security of
the  Company  under  Section  12  of  the  Exchange  Act  and,   following  such
registration,  shall not apply until (i) the earliest of: (A) the first material
modification  of the Plan  (including  any  increase  to the  number  of  shares
reserved  for  issuance  under the Plan in  accordance  with Section 4); (B) the
issuance of all of the shares of common stock  reserved  for issuance  under the
Plan; (C) the  expiration of the Plan; or (D) the first meeting of  stockholders
at which  directors  are to be elected  that occurs after the close of the third
calendar  year   following  the  calendar  year  in  which  occurred  the  first
registration of an equity security under Section 12 of the Exchange Act; or (ii)
such  other  date  required  by  Section  162(m)  of the Code and the  rules and
regulations promulgated thereunder.

6.         OPTION PROVISIONS.

           Each  Option  shall be in such form and shall  contain  such  terms
and conditions  as the Board  shall deem  appropriate.  The  provisions  of
separate Options  need  not  be  identical,   but  each  Option  shall  include
(through incorporation of provisions  hereof by reference in the Option or
otherwise) the substance of each of the following provisions:

           (a)        Term. No Option shall be  exercisable  after the
expiration of ten (10) years from the date it was granted.

           (b)        Price.  The exercise price of each Incentive  Stock Option
shall be not less than one hundred  percent  (100%) of the Fair Market  Value of
the stock subject to the Option on the date the Option is granted.  The exercise
price of each Nonstatutory  Stock Option shall be determined by the Board or the
Committee.  Notwithstanding the foregoing  sentence,  the exercise price of each
Nonstatutory Stock Option granted prior to the date of the first registration of
an equity  security of the Company under Section 12 of the Exchange Act shall be
not less than  eighty-five  percent  (85%) of the Fair Market Value of the stock
subject  to the Option on the date the Option is  granted.  Notwithstanding  the
foregoing,  an Option may be granted with an exercise  price lower than that set
forth above if such Option is granted  pursuant to an assumption or substitution
for another  option in a manner  satisfying  the provisions of Section 424(a) of
the Code.

            (c)        Consideration.  The  purchase  price  of  stock  acquired
pursuant  to an Option  shall be paid,  to the extent  permitted  by  applicable
statutes  and  regulations,  either  (i) in  cash  at the  time  the  Option  is
exercised,  or (ii) at the discretion of the Board or the Committee, at the time
of the grant of the Option, (A) by delivery to the Company of other common stock
of the Company,  (B) according to a deferred payment or other arrangement (which
may include,  

<PAGE>

without limiting the generality of the foregoing, the use of other common stock 
of the Company) with the person to whom the Option is granted or to 
whom the Option is transferred  pursuant to subsection 6(d), or (C) in any other
form of legal consideration that may be acceptable to the Board.

         In the case of any  deferred  payment  arrangement,  interest  shall be
payable at least  annually  and shall be charged at the minimum rate of interest
necessary to avoid the treatment as interest, under any applicable provisions of
the Code,  of any amounts  other than  amounts  stated to be interest  under the
deferred payment arrangement.

           (d)         Transferability.  An  Option  shall  not be  transferable
except  by will  or by the  laws of  descent  and  distribution,  and  shall  be
exercisable during the lifetime of the person to whom the Option is granted only
by such person,  except  that,  after the date of the first  registration  of an
equity  security  of the  Company  under  Section  12 of  the  Exchange  Act,  a
Nonstatutory Stock Option may be transferred by the Optionee upon such terms and
conditions  as are set  forth in the  Option  Agreement  for  such  Nonstatutory
Option,  as the  Board  or the  Committee  shall  determine  in its  discretion,
including (without  limitation)  pursuant to a "domestic relations order" within
the meaning of such rules,  regulations or interpretations of the Securities and
Exchange Commission as are applicable for purposes of Section 16 of the Exchange
Act (a "DRO").  In the event of a transfer of a Nonstatutory  Option as provided
in the Option  Agreement,  the  transferee  shall be entitled  to exercise  such
Nonstatutory  Option  to the  extent  of his or her  interest  received  in such
transfer,  subject  to  the  terms  and  conditions  of  the  Option  Agreement.
Notwithstanding  the foregoing,  the person to whom an Option is granted may, by
delivering written notice to the Company, in a form satisfactory to the Company,
designate a third party who,  in the event of the death of the  Optionee,  shall
thereafter be entitled to exercise the Option.

           (e)        Vesting. The total number of shares of stock subject to an
Option may, but need not, be allotted in periodic  installments  (which may, but
need not, be equal).  The Option  Agreement  may provide  that from time to time
during  each of such  installment  periods,  the Option  may become  exercisable
("vest") with respect to some or all of the shares allotted to that period,  and
may be  exercised  with  respect to some or all of the shares  allotted  to such
period  and/or any prior period as to which the Option became vested but was not
fully exercised. The Option may be subject to such other terms and conditions on
the time or times when it may be exercised (which may be based on performance or
other  criteria) as the Board may deem  appropriate.  The vesting  provisions of
individual options may vary;  provided,  however,  that Options granted prior to
the date of the first  registration  of an equity  security of the Company under
Section 12 of the Exchange Act will in each case provide for vesting of at least
twenty  percent  (20%) per year of the total  number  of shares  subject  to the
Option.  The  provisions  of this  subsection  6(e) are  subject  to any  Option
provisions  governing the minimum  number of shares as to which an Option may be
exercised.

           (f)        Termination of Employment or Relationship as a Director or
Consultant.  In the  event  an  Optionee's  Continuous  Status  as an  Employee,
Director  or  Consultant  terminates  (other than upon the  Optionee's  death or
disability), the Optionee may exercise his or her Option 

<PAGE>

(to the extent that the Optionee was entitled to exercise it at the date of 
termination) but only within such period of time ending on the earlier of (i) 
the date three (3) months after the termination of the Optionee's Continuous 
Status as an Employee,  Director or Consultant (or such longer or shorter period
specified in the Option  Agreement, which period shall be no less than thirty 
(30) days for Options granted prior to the date of the first  registration  of 
an equity  security of the Company under Section  12 of the  Exchange  Act),  
or (ii) the  expiration  of the term of the Option as set forth in the Option 
Agreement. If, at the date of termination, the Optionee  is not  entitled  to  
exercise  his or her entire  Option,  the shares covered by the  unexercisable 
portion of the Option  shall  revert to and again become  available  for  
issuance  under the Plan.  If,  after  termination,  the Optionee  does not 
exercise his or her Option  within the time  specified in the Option  Agreement,
the Option shall  terminate,  and the shares covered by such Option shall revert
to and again become available for issuance under the Plan.

                  An  Optionee's  Option  Agreement may also provide that if the
exercise of the Option  following the  termination of the Optionee's  Continuous
Status as an Employee,  Director,  or Consultant (other than upon the Optionee's
death or  disability)  would  result in  liability  under  Section  16(b) of the
Exchange  Act,  then  the  Option  shall  terminate  on the  earlier  of (i) the
expiration of the term of the Option set forth in the Option Agreement,  or (ii)
the tenth (10th) day after the last date on which such exercise  would result in
such liability under Section 16(b) of the Exchange Act.

           (g)         Disability  of  Optionee.  In  the  event  an  Optionee's
Continuous Status as an Employee,  Director or Consultant terminates as a result
of the  Optionee's  disability,  the Optionee may exercise his or her Option (to
the  extent  that  the  Optionee  was  entitled  to  exercise  it at the date of
termination),  but only  within such period of time ending on the earlier of (i)
the date  twelve  (12)  months  following  such  termination  (or such longer or
shorter period specified in the Option Agreement,  which period shall be no less
than  six (6)  months  for  Options  granted  prior  to the  date  of the  first
registration  of an equity  security  of the  Company  under  Section  12 of the
Exchange  Act), or (ii) the expiration of the term of the Option as set forth in
the  Option  Agreement.  If, at the date of  termination,  the  Optionee  is not
entitled  to  exercise  his or her  entire  Option,  the  shares  covered by the
unexercisable  portion of the Option shall revert to and again become  available
for issuance  under the Plan.  If,  after  termination,  the  Optionee  does not
exercise his or her Option within the time  specified  herein,  the Option shall
terminate,  and the shares  covered  by such  Option  shall  revert to and again
become available for issuance under the Plan.

           (h)         Death of Optionee. In the event of the death of an
Optionee during, or within a period  specified  in the  Option  after  the
termination  of,  the Optionee's Continuous Status as an Employee,  Director or
Consultant, the Option may be exercised (to the extent the Optionee was entitled
to exercise the Option at the date of death) by the  Optionee's  estate,  by a
person who  acquired the right to exercise the Option by bequest or inheritance
or by a person designated to exercise the option upon the Optionee's  death
pursuant to subsection  6(d), but only within the period  ending on the earlier
of (i) the date  eighteen (18) months  following the date of death (or such
longer or shorter period  specified in the Option  Agreement,  which period
shall be no less than six (6) months for Options  granted  prior  to the  date
of the  first  registration  of an  equity 

<PAGE>

security of the  Company  under Section 12 of the  Exchange  Act),  or (ii) the 
expiration of the term of such Option as set forth in the Option Agreement.  If,
at the time of death,  the Optionee  was not  entitled to  exercise  his or her 
entire  Option,  the shares covered by the  unexercisable  portion of the Option
shall revert to and again become  available  for  issuance  under the Plan.  If,
after death, the Option is not exercised within the time specified  herein,  the
Option shall terminate,  and the shares  covered by such Option shall revert to 
and again become available for issuance under the Plan.

           (i)        Early  Exercise.  The Option may, but need not,  include a
provision whereby the Optionee may elect at any time while an Employee, Director
or Consultant to exercise the Option as to any part or all of the shares subject
to the Option  prior to the full vesting of the Option.  Any unvested  shares so
purchased may be subject to a repurchase right in favor of the Company or to any
other restriction the Board determines to be appropriate.

                  With respect to Options granted prior to the date of the first
registration  of an equity  security  of the  Company  under  Section  12 of the
Exchange Act, the right of the Company under this  subsection 6(i) to repurchase
at the original  purchase  price shall lapse at a minimum rate of twenty percent
(20%) per year over five (5) years  from the date the Option  was  granted,  and
(ii) such right  shall be  exercisable  only  within the ninety  (90) day period
following the  termination  of employment or the  relationship  as a Director or
Consultant,  and  (iii)  such  right  shall  be  exercisable  only  for  cash or
cancellation of purchase money indebtedness for the shares. Should such right of
repurchase be assigned by the Company,  the assignee  shall pay the Company cash
equal to the difference between the original purchase price and the stock's Fair
Market Value if the original purchase price is less than the stock's Fair Market
Value.

           (j)        Re-Load Options. Without in any way limiting the authority
of the Board or  Committee  to make or not to make grants of Options  hereunder,
the Board or  Committee  shall have the  authority  (but not an  obligation)  to
include as part of any Option Agreement a provision  entitling the Optionee to a
further  Option (a "Re-Load  Option") in the event the  Optionee  exercises  the
Option evidenced by the Option  agreement,  in whole or in part, by surrendering
other  shares of  Common  Stock in  accordance  with this Plan and the terms and
conditions of the Option  Agreement.  Any such Re-Load Option (i) shall be for a
number of shares equal to the number of shares surrendered as part or all of the
exercise price of such Option;  (ii) shall have an expiration  date which is the
same as the  expiration  date of the Option the  exercise  of which gave rise to
such Re-Load  Option;  and (iii) shall have an exercise  price which is equal to
one hundred  percent (100%) of the Fair Market Value of the Common Stock subject
to  the  Re-Load  Option  on the  date  of  exercise  of  the  original  Option.
Notwithstanding  the  foregoing,  a Re-Load  Option which is an Incentive  Stock
Option (or a  Nonstatutory  Stock Option  granted prior to the date of the first
registration  of an equity  security  of the  Company  under  Section  12 of the
Exchange  Act) and  which is  granted  to a 10%  stockholder  (as  described  in
subsection 5(c)), shall have an exercise price which is equal to one hundred ten
percent  (110%) of the Fair  Market  Value of the stock  subject to the  Re-Load
Option on the date of  exercise  of the  original  Option  and shall have a term
which is no longer than five (5) years.

<PAGE>

         Any  such  Re-Load  Option  may  be  an  Incentive  Stock  Option  or a
Nonstatutory  Stock Option,  as the Board or Committee may designate at the time
of the grant of the original Option; provided,  however, that the designation of
any Re-Load  Option as an  Incentive  Stock  Option  shall be subject to the one
hundred  thousand  dollar  ($100,000)  annual  limitation on  exercisability  of
Incentive Stock Options described in subsection 11(d) of the Plan and in Section
422(d) of the Code.  There shall be no Re-Load Options on a Re-Load Option.  Any
such Re-Load Option shall be subject to the  availability  of sufficient  shares
under subsection 4(a) and shall be subject to such other terms and conditions as
the Board or Committee may determine.

7.        TERMS OF STOCK BONUSES AND PURCHASES OF RESTRICTED STOCK.

         Each stock bonus or restricted  stock  purchase  agreement  shall be in
such form and  shall  contain  such  terms  and  conditions  as the Board or the
Committee  shall deem  appropriate.  The terms and  conditions of stock bonus or
restricted stock purchase agreements may change from time to time, and the terms
and  conditions of separate  agreements  need not be  identical,  but each stock
bonus  or  restricted   stock   purchase   agreement   shall  include   (through
incorporation  of provisions  hereof by reference in the agreement or otherwise)
the substance of each of the following provisions as appropriate:

           (a)         Purchase  Price.  The purchase  price under each
restricted  stock purchase  agreement  shall  be such  amount  as the  Board  or
Committee  shall determine  and  designate  in  such  agreement.
Notwithstanding  the  foregoing sentence,  the purchase price applicable to each
restricted stock purchase grant made prior to the date of the first
registration  of an equity  security of the Company under Section 12 of the
Exchange Act shall be not less than  eighty-five percent  (85%) of the Fair
Market  Value of the stock  subject to the  purchase right on the date such
restricted stock purchase right is granted. In any event, the Board or the
Committee may determine that eligible  participants in the Plan may be awarded
stock pursuant to a stock bonus  agreement in  consideration  for past services
actually rendered to the Company or for its benefit.

           (b)        Transferability.  No rights under a stock bonus or
restricted stock purchase  agreement shall be transferable  except by will or
the laws of descent and  distribution  or,  after  the date of the first
registration  of an equity security of the Company  under  Section 12 of the
Exchange Act, if the agreement so provides,  pursuant to a DRO (as defined in
subsection 6(d) hereof),  so long as stock  awarded  under  such  agreement
remains  subject  to the terms of the agreement.

           (c)       Consideration.  The purchase price of stock acquired
pursuant to a stock  purchase  agreement  shall  be paid  either:  (i) in cash
at the  time of purchase;  (ii) at the discretion of the Board or the Committee,
according to a deferred payment or other arrangement with the person to whom the
stock is sold; or (iii) in any other form of legal  consideration that may be
acceptable to the Board or the Committee in their discretion.  Notwithstanding
the foregoing,  the Board or the Committee to which  administration  of the Plan
has been  delegated may award stock pursuant to a stock bonus  agreement in
consideration  for past services actually rendered to the Company or for its
benefit.

<PAGE>

           (d)        Vesting.  Shares of stock sold or awarded  under the Plan
may, but need  not,  be  subject  to a  repurchase  option  in  favor of the
Company  in accordance  with  a  vesting  schedule  to be  determined  by the
Board  or the Committee;  provided,  however,  with respect to Stock Awards
granted under this Section 7 prior to the date of the first  registration  of
an equity security of the Company  under  Section 12 of the  Exchange  Act,
that (i) the right of the Company to  repurchase at the original  purchase
price shall lapse at a minimum rate of twenty  percent  (20%)  per year  over
five (5) years  from the date the Stock Award was granted,  and (ii) such right
shall be  exercisable  only within the ninety  (90) day period  following  the
termination  of  employment  or the relationship as a Director or Consultant,
(iii) such right shall be exercisable only for cash or cancellation of purchase
money indebtedness for the shares, and (iv) should such right of  repurchase
be assigned by the Company,  the assignee shall pay the Company cash equal to
the difference between the original purchase price and the stock's Fair Market
Value if the original  purchase  price is less than the stock's Fair Market
Value.

           (e)       Termination  of  Employment  or  Relationship  as  a
Director  or Consultant.  In the event a  Participant's  Continuous  Status  as
an  Employee, Director or  Consultant  terminates,  the Company may  repurchase
or  otherwise reacquire,  subject to the limitations  described in subsection
7(d), any or all of the shares of stock held by that person  which have not
vested as of the date of termination  under the terms of the stock bonus or
restricted  stock purchase agreement between the Company and such person.


8.         CANCELLATION AND RE-GRANT OF OPTIONS.

           (a)       The Board or the  Committee  shall have the  authority  to
effect,  at any time and from time to time, (i) the repricing of any outstanding
Options  under the Plan and/or (ii) with the consent of any  adversely  affected
holders of Options,  the cancellation of any outstanding  Options under the Plan
and the grant in  substitution  therefor of new Options  under the Plan covering
the same or different  numbers of shares of stock,  but having an exercise price
per share not less than eighty-five  percent (85%) of the Fair Market Value (one
hundred  percent  (100%) of the Fair  Market  Value in the case of an  Incentive
Stock  Option  or,  in the  case  of an  Option  held by a 10%  stockholder  (as
described in subsection  5(b)),  not less than one hundred ten percent (110%) of
the Fair Market Value) per share of stock on the new grant date.

           (b)        Shares subject to an Option  canceled under this Section 8
shall continue to be counted  against the maximum award of Options  permitted to
be granted  pursuant to subsection  5(c) of the Plan. The repricing of an Option
under this Section 8, resulting in a reduction of the exercise  price,  shall be
deemed to be a cancellation of the original Option and the grant of a substitute
Option;  in the event of such  repricing,  both the original and the substituted
Options shall be counted  against the maximum awards of Options  permitted to be
granted  pursuant  to  subsection  5(c)  of the  Plan.  The  provisions  of this
subsection  8(b)  shall be  applicable  only to the extent  required  by Section
162(m) of the Code.

9.         COVENANTS OF THE COMPANY.

           (a)        During the terms of the Stock  Awards,  the Company  shall
keep  available  at all times the number of shares of stock  required to satisfy
such Stock Awards.

           (b)        The  Company  shall  seek to obtain  from each  regulatory
commission or agency having  jurisdiction over the Plan such authority as may be
required  to issue and sell shares of stock upon  exercise  of the Stock  Award;
provided,  however,  that this  undertaking  shall not  require  the  Company to
register under the Securities  Act of 1933, as amended (the  "Securities  Act"),
either the Plan, any Stock Award or any stock issued or issuable pursuant to any
such Stock Award. If, after reasonable efforts,  the Company is unable to obtain
from any such  regulatory  commission or agency the authority  which counsel for
the Company deems  necessary for the lawful issuance and sale of stock under the
Plan,  the Company shall be relieved from any liability for failure to issue and
sell stock upon exercise of such Stock Awards unless and until such authority is
obtained.

10.        USE OF PROCEEDS FROM STOCK.

         Proceeds  from  the  sale of  stock  pursuant  to  Stock  Awards  shall
constitute general funds of the Company.

11.        MISCELLANEOUS.

           (a)        The Board shall have the power to  accelerate  the time at
which a Stock  Award may first be  exercised  or the time  during  which a Stock
Award or any part thereof will vest pursuant to,  notwithstanding the provisions
in the Stock Award  stating the time at which it may first be  exercised  or the
time during which it will vest.

           (b)         Neither an  Employee,  Director  or  Consultant,  nor any
person to whom a Stock Award is transferred in accordance  with the Plan,  shall
be deemed to be the  holder  of, or to have any of the  rights of a holder  with
respect to, any shares  subject to such Stock Award unless and until such person
has satisfied all  requirements  for exercise of the Stock Award pursuant to its
terms.

           (c)        The Company shall deliver at least  annually to the holder
of any Stock Award a balance sheet and an income  statement.  This section shall
not apply when issuance is limited to key  employees  whose duties in connection
with the Company assure them access to equivalent information.

           (d)        Nothing in the Plan, or any  instrument  executed or Stock
Award granted  pursuant  thereto,  shall confer upon any  Employee,  Director or
Consultant  or other  holder of Stock Awards any right to continue in the employ
of the  Company or any  Affiliate  (or to  continue  acting as a Director  of or
Consultant)  or shall  affect  the  right of the  Company  or any  Affiliate  to
terminate the employment of any Employee with or without cause, the right of the
Company's  Board  and or the  Company's  stockholders  to  remove  any  Director
pursuant  to the  terms  of the

<PAGE>

Company's  By-Laws  and the  provisions  of any applicable  law, or the right to
terminate the  relationship  of any  Consultant pursuant  to the  terms  of such
Consultant's  agreement  with the  Company  or Affiliate.

           (e)        To  the  extent  that  the  aggregate  Fair  Market  Value
(determined at the time of grant) of stock with respect to which Incentive Stock
Options  granted after 1986 are  exercisable  for the first time by any Optionee
during any  calendar  year  under all plans of the  Company  and its  Affiliates
exceeds one hundred thousand dollars ($100,000), the Options or portions thereof
which  exceed  such limit  (according  to the order in which they were  granted)
shall be treated as Nonstatutory Stock Options.

           (f)        The  Company  may require any person to whom a Stock Award
is granted,  or any person to whom a Stock Award is  transferred  in  accordance
with the Plan, as a condition of  exercising or acquiring  stock under any Stock
Award,  (1) to give written  assurances  satisfactory  to the Company as to such
person's  knowledge and  experience in financial and business  matters and/or to
employ a purchaser representative  reasonably satisfactory to the Company who is
knowledgeable and experienced in financial and business matters,  and that he or
she  is  capable  of   evaluating,   alone  or  together   with  the   purchaser
representative,  the merits and risks of exercising the Stock Award;  and (2) to
give  written  assurances  satisfactory  to the Company stating that such person
is acquiring the stock subject to the Stock Award for such person's own account
and not with any present intention of selling or otherwise distributing the
stock.  The foregoing requirements, and any assurances given pursuant to such
requirements, shall be inoperative if (i) the issuance of the shares upon the
exercise or acquisition of stock under the Stock Award  has  been  registered
under a then  currently  effective  registration statement under the Securities
Act, or (ii) as to any particular requirement,  a determination  is made by
counsel for the Company that such requirement need not be met in the
circumstances  under the then  applicable  securities  laws.  The Company  may,
upon  advice of counsel to the  Company,  place  legends on stock certificates
issued under the  Plan  as  such  counsel  deems  necessary  or appropriate in
order to comply with applicable securities laws,  including,  but not limited
to, legends restricting the transfer of the stock.

            (g)       To the  extent  provided  by the  terms  of a Stock  Award
Agreement,  the person to whom a Stock Award is granted may satisfy any federal,
state  or  local  tax  withholding   obligation  relating  to  the  exercise  or
acquisition  of stock under a Stock Award by any of the following  means or by a
combination of such means:  (1) tendering a cash payment;  (2)  authorizing  the
Company  to  withhold  shares  from the  shares of the  common  stock  otherwise
issuable to the  participant as a result of the exercise or acquisition of stock
under the Stock Award;  or (3) delivering to the Company owned and  unencumbered
shares of the common stock of the Company.

12.        ADJUSTMENTS UPON CHANGES IN STOCK.

           (a)        If any change is made in the stock subject to the Plan, or
subject to any Stock Award,  without the receipt of consideration by the Company
(through merger, consolidation, reorganization, recapitalization, 
reincorporation, stock  dividend, dividend in property other than 
cash, stock split, liquidating dividend, combination of shares, exchange of 
shares, change in corporate structure or other  transaction  not  involving  
the  receipt of consideration by the Company), the Plan will be  appropriately  
adjusted in the class(es) and  maximum  number  of  shares  subject  to the Plan
pursuant to subsection 4(a) and the maximum number of shares subject to award to
any person during any calendar year pursuant to subsection 5(c), and the 
outstanding Stock Awards will be appropriately  adjusted in the class(es) and 
number of shares and price  per  share  of stock  subject  to such  outstanding 
Stock  Awards.  Such adjustments  shall be made by the Board or the Committee, 
the  determination of which shall be final, binding and conclusive. (The 
conversion of any convertible securities of the Company shall not be treated as 
a  "transaction  not involving the receipt of consideration by the Company".)

           (b)        In the event of: (1) a dissolution, liquidation or sale of
substantially all of the assets of the Company; (2) a merger or consolidation in
which the Company is not the surviving  corporation;  or (3) a reverse merger in
which the Company is the surviving  corporation  but the shares of the Company's
common  stock  outstanding  immediately  preceding  the merger are  converted by
virtue of the merger  into other  property,  whether in the form of  securities,
cash or otherwise;  or (4) the acquisition by any person, entity or group within
the  meaning of  Section  13(d)(3)  or  14(d)(2)  of the  Exchange  Act,  or any
comparable successor provisions (excluding any employee benefit plan, or related
trust,  sponsored or  maintained by the Company or any Affiliate of the Company)
of the beneficial  ownership (within the meaning of Rule 13d-3 promulgated under
the Exchange  Act, or  comparable  successor  rule) of securities of the Company
representing  at least fifty percent (50%) of the combined voting power entitled
to vote in the  election  of  directors,  then (i) any  surviving  or  acquiring
corporation  shall  assume  Stock  Awards  outstanding  under  the Plan or shall
substitute  similar  Stock  Awards  (including a Stock Award to acquire the same
consideration  paid  to  stockholders  in  the  transaction  described  in  this
subsection  12(b))  for those  outstanding  under the Plan or (ii) to the extent
permitted by applicable law, in the event any surviving or acquiring corporation
refuses to assume such Stock Awards or to  substitute  similar  Stock Awards for
those  outstanding  under the Plan,  (A) with  respect to Stock  Awards  held by
persons then performing  services as Employees,  Directors or  Consultants,  the
vesting  and,  if  applicable,  exercisability  of such  Stock  Awards  shall be
accelerated prior to such event and any Stock Awards requiring exercise shall be
terminated  if not  exercised  after such  acceleration  and at or prior to such
event,  and (B) with  respect to any other Stock  Awards  outstanding  under the
Plan,  such Stock  Awards shall be  terminated  if not  exercised  prior to such
event.

13.        AMENDMENT OF THE PLAN AND STOCK AWARDS.

           (a)        The  Board at any time,  and from time to time,  may amend
the Plan. However, except as provided in Section 12 relating to adjustments upon
changes  in stock,  no  amendment  shall be  effective  unless  approved  by the
stockholders  of the  Company  within  twelve  (12)  months  before or after the
adoption of the amendment, where the amendment will:

                      (i)      Increase  the number of shares  reserved  for
Stock  Awards  under the Plan;

<PAGE>

                      (ii)     Modify the  requirements  as to eligibility for
participation  in the Plan (to the extent such modification requires stockholder
approval in order for the Plan to satisfy the requirements of Section 422 of the
Code); or

                      (iii)    Modify  the  Plan  in any  other  way if  such
modification  requires stockholder  approval  in order  for the Plan to  satisfy
the  requirements  of Section 422 of the Code or to comply with the requirements
of Rule 16b-3.

           (b)        The  Board  may in its sole  discretion  submit  any other
amendment to the Plan for stockholder approval,  including,  but not limited to,
amendments to the Plan intended to satisfy the requirements of Section 162(m) of
the Code and the regulations  promulgated  thereunder regarding the exclusion of
performance-based  compensation  from the limit on  corporate  deductibility  of
compensation paid to certain executive officers.

           (c)        It is expressly  contemplated that the Board may amend the
Plan in any respect the Board deems  necessary or advisable to provide  eligible
Employees,  Directors or Consultants with the maximum benefits provided or to be
provided  under  the  provisions  of the  Code and the  regulations  promulgated
thereunder  relating to Incentive  Stock Options and/or to bring the Plan and/or
Incentive Stock Options granted under it into compliance therewith.

           (d)         Rights  and  obligations  under any Stock  Award  granted
before  amendment of the Plan shall not be impaired by any amendment of the Plan
unless  (i) the  Company  requests  the  consent of the person to whom the Stock
Award was granted and (ii) such person consents in writing.

           (e)        The  Board at any time,  and from time to time,  may amend
the terms of any one or more Stock Award; provided, however, that the rights and
obligations  under any Stock Award  shall not be impaired by any such  amendment
unless  (i) the  Company  requests  the  consent of the person to whom the Stock
Award was granted and (ii) such person consents in writing.

14.        TERMINATION OR SUSPENSION OF THE PLAN.

           (a)        The Board may suspend or  terminate  the Plan at any time.
Unless sooner terminated, the Plan shall terminate on July 15, 2006, which shall
be  within  ten (10)  years  from the date the Plan is  adopted  by the Board or
approved by the  stockholders  of the Company,  whichever  is earlier.  No Stock
Awards may be granted  under the Plan while the Plan is suspended or after it is
terminated.

           (b)        Rights and obligations under any Stock Award granted while
the Plan is in effect shall not be impaired by suspension or  termination of the
Plan, except with the consent of the person to whom the Stock Award was granted.

<PAGE>

15.        EFFECTIVE DATE OF PLAN.

         The Plan shall become  effective  as  determined  by the Board,  but no
Stock Awards granted under the Plan shall be exercised unless and until the Plan
has been approved by the  stockholders  of the Company,  which approval shall be
within  twelve (12)  months  before or after the date the Plan is adopted by the
Board,  and,  if  required,  an  appropriate  permit  has  been  issued  by  the
Commissioner of Corporations of the State of California.



                             INCENTIVE STOCK OPTION


   _________________________, Optionee:

         ALANEX  CORPORATION  (the  "Company"),  pursuant  to  its  1996  Equity
Incentive Plan (the "Plan"),  has granted to you, the optionee  named above,  an
option to purchase shares of the common stock of the Company  ("Common  Stock").
This option is intended to qualify as an  "incentive  stock  option"  within the
meaning of Section 422 of the  Internal  Revenue  Code of 1986,  as amended (the
"Code").

         The grant  hereunder is in connection  with and in  furtherance  of the
Company's compensatory benefit plan for participation of the Company's employees
(including  officers),  directors or consultants  and is intended to comply with
the provisions of Rule 701 promulgated by the Securities and Exchange Commission
under the  Securities  Act of 1933,  as amended (the  "Act").  The grant of this
option and the  issuance  of shares  upon the  exercise  of this option are also
intended  to be exempt from the  securities  qualification  requirements  of the
California  Corporations Code pursuant to Section 25102(o) of that code. Defined
terms not  explicitly  defined in this  agreement  but defined in the Plan shall
have the same definitions as in the Plan.

         The details of your option are as follows:

         1.        TOTAL  NUMBER OF SHARES  SUBJECT TO THIS  OPTION.  The total
number of shares of Common Stock subject to this option is ________ (_________).

         2.        VESTING.  Subject  to the  limitations  contained  herein,
__________ of the shares will vest (become  exercisable) on the ____ day of each
month  following  ______________  and  __________ of the shares will vest on the
final month.  Vesting will be  continuous  until either (i) you cease to provide
services to the Company for any reason, or (ii) this option becomes fully vested
on  _____________.  [Vesting  schedule  subject  to change  from time to time as
determined by the Board of Directors, however, option must vest at least 20% per
year.]

         3.        EXERCISE PRICE AND METHOD OF PAYMENT.

                   (a)       Exercise     Price.     The    exercise    price
 of    this    option    is ___________________________  ($___________)  per
share,  being not less than the fair market value of the Common Stock on the
date of grant of this option.

                   (b)       Method of  Payment.  Payment  of the  exercise
price per share is due in full upon exercise of all or any part of each
installment  which has accrued to you. You may elect, to the extent  permitted
by applicable  statutes and regulations, to make payment of the exercise price
under one of the following alternatives:

<PAGE>

                             (i)       Payment of the  exercise  price per share
in cash  (including check) at the time of exercise;

                             (ii)      Payment  pursuant to a program  developed
under  Regulation T as  promulgated  by the Federal  Reserve  Board which,
prior to the issuance of Common Stock, results in either the receipt of cash (or
check) by the Company or the receipt of irrevocable  instructions to pay the
aggregate  exercise price to the Company from the sales proceeds;

                             (iii)     Provided  that at the time of exercise
the  Company's  Common Stock is  publicly  traded  and quoted  regularly  in the
Wall  Street  Journal, payment by delivery of already-owned shares of Common
Stock, held for the period required to avoid a charge to the Company's  reported
earnings,  and owned free and clear of any liens, claims, encumbrances or
security interests, which Common Stock shall be valued at its fair market value
on the date of exercise; or

                             (iv)      Payment  by  a   combination   of  the
methods  of  payment permitted by subparagraph 3(b)(i) through 3(b)(iii) above.

         4.          WHOLE SHARES.  The minimum number of shares with respect to
which this option may be exercised at any one time is one hundred (100),  except
(a) as to an installment subject to exercise, as set forth in paragraph 2, which
amounts to fewer than one hundred  (100)  shares,  in which case,  the number of
shares in such installment  shall be the minimum number of shares,  and (b) with
respect to the final exercise of this option,  this minimum shall not apply.  In
no event may this  option be  exercised  for any  number of shares  which  would
require the issuance of anything other than whole shares.

         5.          SECURITIES LAW COMPLIANCE.  Notwithstanding anything to the
contrary  contained  herein,  this option may not be exercised unless the shares
issuable upon exercise of this option are then  registered  under the Act or, if
such shares are not then so  registered,  the Company has  determined  that such
exercise and issuance would be exempt from the registration  requirements of the
Act.

         6.          TERM.  The term of this option  commences on  __________,
19__, the date of grant, and expires on  ______________  (the "Expiration Date,"
which date  shall be no more than ten (10)  years  from the date this  option is
granted),  unless this option  expires sooner as set forth below or in the Plan.
In no event may this option be exercised on or after the Expiration  Date.  This
option shall terminate prior to the Expiration Date as follows: three (3) months
after the  termination  of your  Continuous  Status as an Employee,  Director or
Consultant  with the Company or an  Affiliate  of the Company  unless one of the
following circumstances exists:

                     (a)       Your termination of Continuous  Status as an
Employee,  Director or Consultant is due to your  permanent  and total
disability  (within the meaning of Section 422(c)(6)  of the Code).  This
option  will then  expire on the  earlier of the Expiration Date set forth above

<PAGE>

or twelve (12) months following such termination of Continuous Status as an
Employee, Director or Consultant.

                     (b)       Your termination of Continuous  Status as an
Employee,  Director or Consultant is due to your  death.  This  option  will
then  expire on the  earlier  of the Expiration Date set forth above or twelve
(12) months after your death.

                     (c)       If during any part of such three (3) month
period you may not  exercise  your option solely because of the condition set
forth in paragraph 5 above, then your option will not expire until the earlier
of the Expiration  Date set forth above or until this option  shall have been
exercisable  for an  aggregate  period of three (3) months after your
termination  of  Continuous  Status as an Employee, Director or Consultant.

                     (d)       If your  exercise of the option within three (3)
months after  termination  of your Continuous  Status as an Employee,  Director
or Consultant with the Company or with an Affiliate of the Company  would
result in  liability  under  section 16(b) of the  Securities  Exchange Act of
1934,  then your option will expire on the earlier of (i) the  Expiration  Date
set forth above,  (ii) the tenth (10th) day after the last date upon which
exercise  would result in such  liability or (iii) six (6) months and ten (10)
days after the  termination of your Continuous Status as an Employee,  Director
or Consultant  with the Company or an Affiliate of the Company.

         However,   this  option  may  be  exercised  following  termination  of
Continuous Status as an Employee,  Director or Consultant only as to that number
of  shares  as to  which  it was  exercisable  on the  date  of  termination  of
Continuous Status as an Employee, Director or Consultant under the provisions of
paragraph 2 of this option.

         In order to obtain the federal income tax advantages associated with an
"incentive  stock option," the Code requires that at all times  beginning on the
date of grant of the option  and  ending on the day three (3) months  before the
date of the  option's  exercise,  you must be an  employee  of the Company or an
Affiliate  of the Company,  except in the event of your death or  permanent  and
total  disability.  The Company has provided for  continued  vesting or extended
exercisability of your option under certain  circumstances for your benefit, but
cannot  guarantee that your option will  necessarily be treated as an "incentive
stock  option" if you provide  services to the  Company or an  Affiliate  of the
Company as a consultant or exercise your option more than three (3) months after
the date your  employment  with the  Company and all  Affiliates  of the Company
terminates.

         7.          EXERCISE.

                     (a)      This  option may be  exercised,  to the  extent
specified  above,  by delivering a notice of exercise (in a form  designated by
the Company)  together with the exercise price to the Secretary of the Company,
or to such other person as the Company may designate,  during regular business
hours, together with such additional  documents  as the Company may then
require  pursuant to  subsection 12(f) of the Plan.

<PAGE>

                     (b)      By exercising this option you agree that:

                              (i)       as a  precondition  to the completion of
any exercise of this option,  the Company may require you to enter an
arrangement  providing for the payment by you to the Company of any tax
withholding  obligation of the Company arising  by  reason of (1) the  exercise
of this  option;  (2) the lapse of any substantial  risk of  forfeiture  to
which the shares are subject at the time of exercise; or (3) the disposition of
shares acquired upon such exercise;

                              (ii)      you will notify the Company in writing
within  fifteen  (15) days after the date of any  disposition of any of the
shares of the Common Stock issued upon  exercise of this option that occurs
within two (2) years after the date of this  option  grant or within one (1)
year  after such  shares of Common Stock are transferred upon exercise of this
option; and

                              (iii)     the Company (or a representative  of the
underwriters)  may, in connection  with the first  underwritten  registration
of the offering of any securities of the Company under the Act,  require that
you not sell or otherwise transfer  or dispose of any shares of Common  Stock or
other  securities  of the Company  during  such  period  (not to exceed one
hundred  eighty  (180)  days) following  the  effective  date  (the  "Effective
Date")  of  the  registration statement of the Company  filed under the Act as
may be requested by the Company or the  representative of the  underwriters.
You further agree that the Company may impose stop-transfer  instructions with
respect to securities subject to the foregoing restrictions until the end of
such period.

         8.          TRANSFERABILITY. This option is not transferable, except by
will or by the laws of descent and distribution,  and is exercisable during your
life only by you. Notwithstanding the foregoing, by delivering written notice to
the Company,  in a form  satisfactory to the Company,  you may designate a third
party who, in the event of your death,  shall thereafter be entitled to exercise
this option.

         9.           OPTION  NOT A  SERVICE  CONTRACT.  This  option  is not an
employment  contract and nothing in this option shall be deemed to create in any
way  whatsoever  any  obligation  on your part to  continue in the employ of the
Company,  or of the Company to continue  your  employment  with the Company.  In
addition,  nothing in this option shall obligate the Company or any Affiliate of
the Company, or their respective stockholders,  Board of Directors,  officers or
employees  to continue  any  relationship  which you might have as a Director or
Consultant for the Company or Affiliate of the Company.

         10.          NOTICES.  Any notices  provided for in this option or the
Plan  shall be given in  writing  and shall be  deemed  effectively  given  upon
receipt or, in the case of notices  delivered  by the  Company to you,  five (5)
days after deposit in the United States mail, postage prepaid,  addressed to you
at the  address  specified  below  or at such  other  address  as you  hereafter

                            NONSTATUTORY STOCK OPTION


 _____________________________, Optionee:

         ALANEX  CORPORATION  (the  "Company"),  pursuant  to  its  1996  Equity
Incentive Plan (the "Plan"),  has granted to you, the optionee  named above,  an
option to purchase shares of the common stock of the Company  ("Common  Stock").
This option is not intended to qualify and will not be treated as an  "incentive
stock option" within the meaning of Section 422 of the Internal  Revenue Code of
1986, as amended (the "Code").

         The grant  hereunder is in connection  with and in  furtherance  of the
Company's compensatory benefit plan for participation of the Company's employees
(including  officers),  directors or consultants  and is intended to comply with
the provisions of Rule 701 promulgated by the Securities and Exchange Commission
under the  Securities  Act of 1933,  as amended (the  "Act").  The grant of this
option and the  issuance  of shares  upon the  exercise  of this option are also
intended  to be exempt from the  securities  qualification  requirements  of the
California  Corporations Code pursuant to Section 25102(o) of that code. Defined
terms not  explicitly  defined in this  agreement  but defined in the Plan shall
have the same definitions as in the Plan.

         The details of your option are as follows:

         1.        TOTAL  NUMBER OF SHARES  SUBJECT TO THIS  OPTION. The total
number of shares of Common Stock subject to this option is ______________
(___________).


         2.        VESTING.  Subject  to the  limitations  contained  herein,
__________ of the shares will vest (become  exercisable) on the ____ day of each
month  following  ______________  and  __________ of the shares will vest on the
final month.  Vesting will be  continuous  until either (i) you cease to provide
services to the Company for any reason, or (ii) this option becomes fully vested
on  _____________.  [Vesting  schedule  subject  to change  from time to time as
determined by the Board of Directors, however, option must vest at least 20% per
year.]

         3.        EXERCISE PRICE AND METHOD OF PAYMENT.

                   (a)     Exercise Price.  The exercise price of this option
 is ______________ ($_______________) per share,  being not less than 85% of the
fair market value of the Common  Stock  on the date of grant of this option.

                   (b)     Method of  Payment.  Payment  of the  exercise
price per share is due in full upon exercise of all or any part of each
installment which has accrued to you. You may elect, to the extent  permitted by
applicable statutes and regulations, to make payment of the exercise price under
one of the following alternatives:

<PAGE>

                          (i)       Payment of the  exercise  price per
share in cash (including check) at the time of exercise;

                          (ii)      Payment  pursuant to a program
developed under  Regulation T as  promulgated  by the Federal  Reserve  Board
which,  prior to the issuance of Common Stock, results in either the receipt of
cash (or check) by the Company or the receipt of irrevocable  instructions to
pay the aggregate  exercise price to the Company from the sales proceeds;

                          (iii)     Provided  that at the time of exercise
the  Company's  Common Stock is  publicly  traded  and quoted  regularly  in the
Wall  Street  Journal, payment by delivery of already-owned shares of Common
Stock, held for the period required to avoid a charge to the Company's  reported
earnings,  and owned free and clear of any liens, claims, encumbrances or
security interests, which Common Stock shall be valued at its fair market value
on the date of exercise; or

                              (iv)      Payment  by  a   combination   of  the
methods  of  payment permitted by subparagraph 3(b)(i) through 3(b)(iii) above.

         4.        WHOLE SHARES.  The minimum number of shares with respect to
which this option may be exercised at any one time is one hundred (100),  except
(a) as to an installment subject to exercise, as set forth in paragraph 2, which
amounts to fewer than one hundred  (100)  shares,  in which case,  the number of
shares in such installment  shall be the minimum number of shares,  and (b) with
respect to the final exercise of this option,  this minimum shall not apply.  In
no event may this  option be  exercised  for any  number of shares  which  would
require the issuance of anything other than whole shares.

         5.        SECURITIES LAW COMPLIANCE.  Notwithstanding anything to the 
contrary  contained  herein,  this option may not be exercised unless the shares
issuable upon exercise of this option are then  registered  under the Act or, if
such shares are not then so  registered,  the Company has  determined  that such
exercise and issuance would be exempt from the registration  requirements of the
Act.

         6.        TERM. The term of this option commences on _________, 19__,
the date of grant and expires on  _____________________  (the "Expiration Date,"
which date  shall be no more than ten (10)  years  from the date this  option is
granted),  unless this option  expires sooner as set forth below or in the Plan.
In no event may this option be exercised on or after the Expiration  Date.  This
option shall terminate prior to the Expiration Date as follows: three (3) months
after the  termination  of your  Continuous  Status as an Employee,  Director or
Consultant with the Company or an Affiliate of the Company for any reason or for
no reason unless:

                   (a)       such termination of Continuous  Status as an
Employee,  Director or Consultant is due to your  permanent  and total
disability  (within the meaning of Section 422(c)(6) of the Code), in which
event the option shall expire on the earlier of the  Expiration  Date set 

<PAGE>

forth above or twelve  (12)  months  following  such termination of Continuous 
Status as an Employee, Director or Consultant; or

                   (b)       such termination of Continuous  Status as an
Employee,  Director or Consultant is due to your death,  in which event the
option  shall expire on the earlier of the Expiration Date set forth above or
twelve (12) months after your death; or

                   (c)       during any part of such three (3) month  period the
option is not  exercisable solely  because of the condition set forth in
paragraph 5 above,  in which event the option shall not expire until the earlier
of the  Expiration  Date set forth above or until it shall have been
exercisable for an aggregate  period of three (3) months after the termination
of Continuous  Status as an Employee,  Director or Consultant; or

                   (d)       exercise  of the option  within  three (3) months
after  termination  of your Continuous  Status as an Employee,  Director or
Consultant  with the Company or with an Affiliate of the Company  would result
in liability  under section 16(b) of the Securities  Exchange Act of 1934 (the
"Exchange  Act), in which case the option will expire on the earlier of (i) the
Expiration  Date set forth  above, (ii) the tenth (10th) day after the last date
upon which  exercise  would result in such  liability  or  (iii)  six  (6)
months  and ten  (10)  days  after  the termination  of your  Continuous  Status
as an Employee,  Director or Consultant with the Company or an Affiliate of the
Company.

         However,   this  option  may  be  exercised  following  termination  of
Continuous Status as an Employee,  Director or Consultant only as to that number
of  shares  as to  which  it was  exercisable  on the  date  of  termination  of
Continuous Status as an Employee, Director or Consultant under the provisions of
paragraph 2 of this option.

         7.       EXERCISE.

                  (a)        This option may be exercised,  to the extent
specified above, by delivering a notice of exercise  (in a form  designated  by
the  Company)  together  with the exercise  price to the Secretary of the
Company,  or to such other person as the Company  may  designate,  during
regular  business  hours,  together  with such additional  documents  as the
Company may then  require  pursuant to  subsection 12(f) of the Plan.

                  (b)        By exercising this option you agree that:

                             (i)       as a  precondition  to the completion of
any exercise of this option,  the Company may require you to enter an
arrangement  providing for the cash  payment by you to the  Company of any tax
withholding  obligation  of the Company arising by reason of: (1) the exercise
of this option;  (2) the lapse of any  substantial  risk of forfeiture to which
the shares are subject at the time of exercise;  or (3) the disposition of
shares acquired upon such exercise.  You also agree that any exercise of this
option has not been  completed and that the Company is under no  obligation  to
issue any Common  Stock to you until such an arrangement 

<PAGE>

is  established or the Company's tax  withholding  obligations  are satisfied, 
as determined by the Company; and

                             (ii)      the Company (or a representative  of the
underwriters)  may, in connection  with the first  underwritten  registration of
the offering of any securities of the Company under the Act,  require that you
not sell or otherwise transfer  or dispose of any shares of Common  Stock or
other  securities  of the Company  during  such  period  (not to exceed one
hundred  eighty  (180)  days) following  the  effective  date  (the  "Effective
Date")  of  the  registration statement of the Company  filed under the Act as
may be requested by the Company or the  representative of the  underwriters.
You further agree that the Company may impose stop-transfer  instructions with
respect to securities subject to the foregoing restrictions until the end of
such period.

         8.        TRANSFERABILITY. This option is not transferable, except by
will or by the laws of descent and distribution,  and is exercisable during your
life only by you. Notwithstanding the foregoing, by delivering written notice to
the Company,  in a form  satisfactory to the Company,  you may designate a third
party who, in the event of your death,  shall thereafter be entitled to exercise
this option.

         9.        OPTION  NOT A  SERVICE  CONTRACT.  This  option  is not an
employment  contract and nothing in this option shall be deemed to create in any
way  whatsoever  any  obligation  on your part to  continue in the employ of the
Company,  or of the Company to continue  your  employment  with the Company.  In
addition,  nothing in this option shall obligate the Company or any Affiliate of
the Company, or their respective stockholders,  Board of Directors, officers, or
employees  to continue  any  relationship  which you might have as a Director or
Consultant for the Company or Affiliate of the Company.

         10.       NOTICES.  Any notices  provided for in this option or the
Plan  shall be given in  writing  and shall be  deemed  effectively  given  upon
receipt or, in the case of notices  delivered  by the  Company to you,  five (5)
days after deposit in the United States mail, postage prepaid,  addressed to you
at the  address  specified  below  or at such  other  address  as you  hereafter
designate by written notice to the Company.

         11.       GOVERNING PLAN DOCUMENT. This option is subject to all the
provisions  of the Plan, a copy of which is attached  hereto and its  provisions
are  hereby  made a part  of  this  option,  including  without  limitation  the
provisions  of  Section  6 of the Plan  relating  to option  provisions,  and is

                            NONSTATUTORY STOCK OPTION



                   MARVIN R. BROWN, Optionee:

                   ALANEX  CORPORATION  (the  "Company") has this day granted to
you, the optionee named above,  an option to purchase shares of the common stock
of the Company ("Common  Stock").  This option is not intended to qualify as and
will not be treated as an "incentive stock option" within the meaning of Section
422 of the Internal Revenue Code of 1986, as amended (the "Code").

                   The grant  hereunder is in connection with and in furtherance
of the Company's  compensatory  benefit plan for  participation of the Company's
employees  (including  officers,  directors and  consultants) and is intended to
comply  with  the  provisions  of Rule 701  promulgated  by the  Securities  and
Exchange Commission under the Securities Act of 1933, as amended (the "Act") and
to satisfy the  requirements  of Section  25102(f) of the  California  Corporate
Securities Law of 1968, as amended.

                   The details of your option are as follows:

         1. Number of Option  Shares and Vesting.  The total number of shares of
Common Stock subject to this option is One Hundred Thousand  (100,000).  Subject
to  the  limitations  contained  herein,  this  option  shall  vest  and  become
exercisable  over a three  year  period  beginning  as of the date  hereof  at a
monthly rate of 2,777.78 shares.

         2. (a)  Exercise Price.  The exercise price of this option is ten cents
($.10) per share.

            (b)  Method of Payment. Payment of the exercise price per share
is due in full upon  exercise of all or any part of each  installment  which has
accrued to you. You may elect,  to the extent  permitted by applicable  statutes
and  regulations,  to  make  payment  of the  exercise  price  under  one of the
following alternatives:

                 (i)       Payment of the exercise price per share in cash
(including  check) at the time of exercise;

                 (ii)      Payment pursuant to a program  developed under
Regulation T as promulgated by the Federal Reserve Board which, prior to the
issuance of Common Stock,  results in either  the  receipt  of cash (or  check)
by the  Company  or the  receipt of irrevocable instructions to pay the
aggregate exercise price to the Company from the sales proceeds;

<PAGE>

                 (iii)     Provided that at the time of exercise the  Company's
Common Stock is publicly traded and quoted  regularly in the Wall Street
Journal,  payment by delivery of already-owned  shares of Common Stock,  held
for the period  required to avoid a charge to the  Company's  reported
earnings,  and  owned  free and clear of any liens, claims,  encumbrances or
security interests,  which Common Stock shall be valued  at its fair  market
value on the date of  exercise  of the  option,  or portion thereof, granted
hereunder;

                 (iv)      Provided  that the  option  exercise  price for the
installment,  or  portion thereof,  being  purchased is at least one thousand
dollars  ($1,000),  payment pursuant to the deferred  payment  alternative  as
described in paragraph  2(c) hereof; or

                 (v)       Payment by a combination of the methods of payment
permitted by  subparagraph 2(b)(i) through 2(b)(iv) above.

            (c)       Conditions  of  Deferred  Payment.  In the event that you
elect to make  payment of the exercise price pursuant to the deferred payment
alternative:

                 (i)       Not less than twenty-five  percent (25%) of the
 aggregate exercise price shall be due at the time of exercise,  not less than
twenty-five percent (25%) of said exercise price, plus accrued interest,  shall
be due each year after the date of exercise, and final payment of the remainder
of the exercise price, plus accrued interest,  shall be due  three (3) years
from the date of  exercise  or, at the Company's  election,  upon termination of
your employment with the Company or an affiliate of the Company;

                 (ii)      Interest  shall be  payable  at least  annually  and
shall be  charged  at the minimum rate of interest necessary to avoid the
treatment as interest, under any applicable  provisions  of the Code,  of any
portion of any  amounts  other than amounts stated to be interest under the
deferred payment arrangement; and

                 (iii)     In order to elect the deferred  payment  alternative,
you must,  as a part of your  written  notice of  exercise,  give notice of the
election of this payment alternative  and, in order to secure the payment of the
deferred  exercise price to the Company  hereunder,  if the Company so
requests,  you must tender to the Company a  promissory  note and a  security
agreement  covering  the  purchased shares, both in form and substance
satisfactory to the Company,  and such other or additional documentation as the
Company may request.

         3. Securities Law Compliance.  Notwithstanding anything to the contrary
contained  herein,  this option may not be exercised  unless the shares issuable
upon  exercise  of this  option  are then  registered  under the Act or, if such
shares are not then so registered, the Company has determined that such exercise
and issuance would be exempt from the registration  requirements of the Act. You
represent that you (i) are an officer or 

<PAGE>

director of the Company, or (ii) have a preexisting personal or business 
relationship with the Company or one or more of its officers,  directors,  or
controlling  persons,  or (iii) by reason of your business or financial 
experience or the business or financial experience of your professional  
advisors  who are  unaffiliated  with and who are not  directly or indirectly
compensated by the Company or any affiliate of the Company, you have the 
capacity to protect your own interests in connection  with the grant of this
option.  You also  represent  that you are  acquiring  this  option for your own
account and not with a view to or for sale in connection  with any  distribution
of this  security.  You  also  represent  that  you have  acquired  this  option
unaccompanied  by the  publication of any  advertisement.  The Company may, upon
advice of counsel to the Company,  place  legends on stock  certificates  issued
pursuant to the  exercise of this option as such  counsel  deems  necessary  and
appropriate in order to comply with applicable securities laws,  including,  but
not limited to, legends restricting the transfer of stock.

         4. Minimum Exercise. The minimum number of shares with respect to which
this option may be exercised at any one time is one hundred (100), except (a) as
to an  installment  subject  to  exercise,  as set forth in  paragraph  1, which
amounts  to fewer  than one  hundred  (100)  shares,  in which  case,  as to the
exercise of that installment,  the number of shares in such installment shall be
the minimum number of shares, and (b) with respect to the final exercise of this
option this  minimum  shall not apply.  In no event may this option be exercised
for any number of shares which would require the issuance of anything other than
whole shares.

         5. Term.  The term of this  option  commences  on January 19, 1996 (the
date of grant) and, unless sooner  terminated as set forth below,  terminates on
January  18,  2006 (the  "Expiration  Date" which date shall be no more than ten
(10) years from the date this option is granted). In no event may this option be
exercised  on or  after  the  date on which it  terminates.  This  option  shall
terminate prior to the expiration of its term as follows: three (3) months after
the  termination  of your  continuous  service to the  Company  as an  employee,
consultant or director (your "Termination Date") for any reason or for no reason
unless:

            (a)  such  termination of service is due to your permanent and
total disability (within the meaning of Section 422(c)(6) of the Code), in which
event the option shall terminate on the earlier of the Expiration Date set forth
above or twelve (12) months following your Termination Date; or

            (b)  such termination of service is due to your death, in which
event the option shall terminate on the earlier of the Expiration Date set forth
above or eighteen (18) months after your death; or

<PAGE>

            (c)  during any part of such three (3) month  period the option
is not  exercisable  solely  because of the  condition  set forth in paragraph 3
above,  in which event the option shall not  terminate  until the earlier of the
Expiration  Date set forth above or until it shall have been  exercisable for an
aggregate period of three (3) months after your Termination Date; or

            (d)  exercise of the option  within three (3) months after your
Termination Date would result in liability under section 16(b) of the Securities
Exchange Act of 1934, in which case the option will  terminate on the earlier of
(i) the  Expiration  Date set forth  above,  (ii) the tenth (10th) day after the
last date upon which  exercise  would result in such  liability or (iii) six (6)
months  and ten (10) days  after your  Termination  Date with the  Company or an
affiliate of the Company.

                   This option may be exercised  following your Termination Date
only  as to that  number  of  shares  as to  which  it was  exercisable  on your
Termination Date under the provisions of paragraph 1 of this option.

         6. Exercise. (a) This option may be exercised,  to the extent specified
above,  by delivering a notice of exercise (in a form designated by the Company)
together  with the exercise  price to the  Secretary of the Company,  or to such
other  person as the Company  may  designate,  during  regular  business  hours,
together  with such  additional  documents  as the Company  may then  reasonably
require.

            (b)  By exercising this option you agree that:

                 (i)       as a  precondition  to the  completion  of any
exercise of this  option,  the Company may require you to enter an  arrangement
providing for the cash payment by you to the Company of any tax  withholding
obligation of the Company arising by reason of: (1) the exercise of this option;
(2) the lapse of any substantial risk of forfeiture  to which the shares are
subject at the time of exercise;  or (3) the disposition of shares acquired upon
such exercise; and

                 (ii)      the Company (or a representative of the underwriters)
may, in connection with the first  underwritten  registration  of the offering
of any  securities of the Company  under  the Act,  require  that you not sell
or  otherwise  transfer  or dispose of any shares of Common Stock or other
securities of the Company during such  period  (not to exceed  one  hundred
eighty  (180)  days)  following  the effective  date (the  "Effective  Date") of
the  registration  statement  of the Company  filed  under  the  Act as  may  be
requested  by  the  Company  or the representative  of the  underwriters.  You
further  agree that the  Company may impose  stop-transfer  instructions  with
respect to  securities  subject to the foregoing restrictions until the end of
such period.

<PAGE>

         7. Covenant of Company.  During the term of this option,  the
Company  shall keep  available at all times the number of shares of stock
required to satisfy the exercise of such option.

         8. Adjustment  Upon Changes in Stock.  (a) If any change is made in the
stock subject to this option  (through  merger,  consolidation,  reorganization,
recapitalization,  stock dividend,  dividend in property other than cash,  stock
split,  liquidating dividend,  combination of shares, exchange of shares, change
in  corporate  structure  or other  transaction  not  involving  the  receipt of
consideration by the Company), this option will be appropriately adjusted in the
type(s)  and number of  securities  and price per share of stock  subject to the
option.  Such  adjustments  shall  be  made  by  the  Board  of  Directors,  the
determination of which shall be final,  binding and conclusive.  (The conversion
of any  convertible  securities  of  the  Company  shall  not  be  treated  as a
"transaction not involving the receipt of consideration by the Company.")

            (b)       In the event of:  (i) a merger or  consolidation  in which
the Company is not the surviving corporation;  or (ii) a reverse merger in which
the Company is the surviving  corporation but the shares of the Company's common
stock  outstanding  immediately  preceding the merger are converted by virtue of
the merger  into other  property,  whether  in the form of  securities,  cash or
otherwise;  or (iii) a sale of all or  substantially  all of the  assets  of the
Company,  then,  to the extent  permitted by  applicable  law: (1) any surviving
corporation  shall  assume  this  option or shall  substitute  a similar  option
(including an option to acquire the same  consideration  paid to stockholders in
the transaction  described in this  subparagraph  8(b)), if this option is still
outstanding,  or (2) in the event any surviving corporation refuses to assume or
continue  this option,  or to  substitute  a similar  option for this option (if
still  outstanding),  then this option shall become fully vested and exercisable
prior to such event and shall  terminate  after such  acceleration of vesting if
not exercised at or prior to such corporate event. In the event of a dissolution
or  liquidation  of the  Company,  this  option  (if  still  outstanding)  shall
terminate if not exercised prior to such event.

         9. Transferability.  This option is not transferable, except by will or
by the laws of descent and  distribution,  and is  exercisable  during your life
only by you. By delivering written notice to the Company, in a form satisfactory
to the Company, you may designate a third party who, in the event of your death,
shall thereafter be entitled to exercise this option.

         10. Option Not a Service  Contract.  This option is not an  employment
contract  and  nothing  in this  option  shall be  deemed  to  create in any way
whatsoever any obligation on your part to continue in the employ of the Company,
or of the Company to continue  your  employment  with the Company.  In the event
that  this  option is  granted  to you in  connection  with the  performance  of
services  as a  consultant  or  director,  or in the 

<PAGE>

event  that this  option is granted to you in connection with the performance of
services as an employee and you  subsequently  perform  services as a consultant
or director,  references to employment,   employee  and  similar  terms  shall  
be  deemed  to  include  the performance  of services  as a  consultant  or a  
director,  as the case may be, provided,  however,  that no rights as an 
employee  shall arise by reason of the use of such terms.

         11. Notices.  Any notices provided for in this option shall be given in
writing and shall be deemed  effectively  given upon  receipt or, in the case of
notices  delivered  by the  Company to you,  five (5) days after  deposit in the
United States mail,  postage prepaid,  addressed to you at the address specified
below or at such other address as you hereafter  designate by written  notice to
the Company.

         12. Amendment.  This  option  may be  amended  by the  Board of
Directors  at any  time;  provided, however,  that any change that would
adversely  affect your rights in this option must first be approved by you in
writing before becoming effective.

         13. Administration.  This  option is subject  to all  interpretations,
amendments, rules and regulations which may from time to time be promulgated and
adopted by the Company.  This authority shall be exercised by the Board, or by a
committee  of one or more  members  of the  Board in the  event  that the  Board
delegates  its  authority  to a  committee.  The  Board,  in  exercise  of  this
authority, may correct any defect, omission or inconsistency in this option in a
manner and to the extent the Board shall deem  necessary  or  desirable  to make
this option fully effective. References to the Board shall mean the committee if
a committee has been appointed by the Board.  Any  interpretations,  amendments,
rules and  regulations  promulgated by the Board shall be final and binding upon
the  Company  and its  successors  in  interest  as well as you and your  heirs,
assigns, and other successors in interest.

<PAGE>

         14.  Rights as  Stockholder.  Neither  you nor any  person to whom this
option is transferred under paragraph 8 of this option shall be deemed to be the
holder of, or to have any of the rights of a holder with  respect to, any shares
subject  to  this  option  unless  and  until  such  person  has  satisfied  all
requirements for exercise of this option pursuant to its terms.

         Dated as of the 19th day of January, 1996.

                                            Very truly yours,

                                            ALANEX CORPORATION

                            NONSTATUTORY STOCK OPTION



                   ALEXANDER POLINSKY, Optionee:

                   ALANEX  CORPORATION  (the  "Company") has this day granted to
you, the optionee named above,  an option to purchase shares of the common stock
of the Company ("Common  Stock").  This option is not intended to qualify as and
will not be treated as an "incentive stock option" within the meaning of Section
422 of the Internal Revenue Code of 1986, as amended (the "Code").

                   The grant  hereunder is in connection with and in furtherance
of the Company's  compensatory  benefit plan for  participation of the Company's
employees  (including  officers,  directors and  consultants) and is intended to
comply  with  the  provisions  of Rule 701  promulgated  by the  Securities  and
Exchange Commission under the Securities Act of 1933, as amended (the "Act") and
to satisfy the  requirements  of Section  25102(f) of the  California  Corporate
Securities Law of 1968, as amended.

                   The details of your option are as follows:

         1. Number of Option  Shares and Vesting.  The total number of shares of
Common Stock subject to this option is Fifty Thousand  (50,000).  Subject to the
limitations contained herein, this option shall vest and become exercisable over
a three  year  period  beginning  as of the date  hereof  at a  monthly  rate of
1,388.89 shares.

         2.    (a)     Exercise Price.  The exercise price of this option is ten
cents ($.10) per share.

               (b)    Method of Payment. Payment of the exercise price per share
is due in full upon  exercise of all or any part of each  installment  which has
accrued to you. You may elect,  to the extent  permitted by applicable  statutes
and  regulations,  to  make  payment  of the  exercise  price  under  one of the
following alternatives:

                      (i)       Payment of the exercise price per share in cash
(including  check) at the time of exercise;

                      (ii)      Payment pursuant to a program  developed under
Regulation T as promulgated by the Federal Reserve Board which, prior to the
issuance of Common Stock,  results in either  the  receipt  of cash (or  check)
by the  Company  or the  receipt of irrevocable instructions to pay the
aggregate exercise price to the Company from the sales proceeds;

<PAGE>

                      (iii)     Provided that at the time of exercise the
Company's  Common Stock is publicly traded and quoted  regularly in the Wall
Street Journal,  payment by delivery of already-owned  shares of Common Stock,
held for the period  required to avoid a charge to the  Company's  reported
earnings,  and  owned  free and clear of any liens, claims,  encumbrances or
security interests,  which Common Stock shall be valued  at its fair  market
value on the date of  exercise  of the  option,  or portion thereof, granted
hereunder;

                      (iv)      Provided  that the  option  exercise  price for
the  installment,  or  portion thereof,  being  purchased is at least one
thousand  dollars  ($1,000),  payment pursuant to the deferred  payment
alternative  as  described in paragraph  2(c) hereof; or

                      (v)       Payment by a combination of the methods of
payment  permitted by  subparagraph 2(b)(i) through 2(b)(iv) above.

               (c)     Conditions  of  Deferred  Payment.  In the event that you
elect to make  payment of the exercise price pursuant to the deferred payment
alternative:

                      (i)       Not less than twenty-five  percent (25%) of the
aggregate exercise price shall be due at the time of exercise,  not less than
twenty-five percent (25%) of said exercise price, plus accrued interest,  shall
be due each year after the date of exercise, and final payment of the remainder
of the exercise price, plus accrued interest,  shall be due  three (3) years
from the date of  exercise  or, at the Company's  election,  upon termination of
your employment with the Company or an affiliate of the Company;

                      (ii)      Interest  shall be  payable  at least  annually
and shall be  charged  at the minimum rate of interest necessary to avoid the
treatment as interest, under any applicable  provisions  of the Code,  of any
portion of any  amounts  other than amounts stated to be interest under the
deferred payment arrangement; and

                      (iii)     In order to elect the deferred  payment
alternative,  you must,  as a part of your  written  notice of  exercise,  give
notice of the election of this payment alternative  and, in order to secure the
payment of the deferred  exercise price to the Company  hereunder,  if the
Company so  requests,  you must tender to the Company a  promissory  note and a
security  agreement  covering  the  purchased shares, both in form and substance
satisfactory to the Company,  and such other or additional documentation as the
Company may request.

         3. Securities Law Compliance.  Notwithstanding anything to the contrary
contained  herein,  this option may not be exercised  unless the shares issuable
upon  exercise  of this  option  are then  registered  under the Act or, if such
shares are not then so registered, the Company has determined that such exercise
and issuance would be exempt from the registration  requirements of the Act. You
represent that you (i) are an officer or 

<PAGE>

director of the Company, or (ii) have a preexisting personal or business 
relationship with the Company or one or more of its officers,  directors,  or 
controlling  persons,  or (iii) by reason of your business or financial 
experience or the business or financial experience of your professional  
advisors  who are  unaffiliated  with and who are not  directly or indirectly  
compensated by the Company or any affiliate of the Company, you have 
the capacity to protect your own interests in connection  with the grant of this
option.  You also  represent  that you are  acquiring  this  option for your own
account and not with a view to or for sale in connection  with any  distribution
of this  security.  You  also  represent  that  you have  acquired  this  option
unaccompanied  by the  publication of any  advertisement.  The Company may, upon
advice of counsel to the Company,  place  legends on stock  certificates  issued
pursuant to the  exercise of this option as such  counsel  deems  necessary  and
appropriate in order to comply with applicable securities laws,  including,  but
not limited to, legends restricting the transfer of stock.

         4. Minimum Exercise. The minimum number of shares with respect to which
this option may be exercised at any one time is one hundred (100), except (a) as
to an  installment  subject  to  exercise,  as set forth in  paragraph  1, which
amounts  to fewer  than one  hundred  (100)  shares,  in which  case,  as to the
exercise of that installment,  the number of shares in such installment shall be
the minimum number of shares, and (b) with respect to the final exercise of this
option this  minimum  shall not apply.  In no event may this option be exercised
for any number of shares which would require the issuance of anything other than
whole shares.

         5. Term.  The term of this  option  commences  on January 19, 1996 (the
date of grant) and, unless sooner  terminated as set forth below,  terminates on
January  18,  2006 (the  "Expiration  Date" which date shall be no more than ten
(10) years from the date this option is granted). In no event may this option be
exercised  on or  after  the  date on which it  terminates.  This  option  shall
terminate prior to the expiration of its term as follows: three (3) months after
the  termination  of your  continuous  service to the  Company  as an  employee,
consultant or director (your "Termination Date") for any reason or for no reason
unless:

               (a)    such  termination of service is due to your permanent and
total disability (within the meaning of Section 422(c)(6) of the Code), in which
event the option shall terminate on the earlier of the Expiration Date set forth
above or twelve (12) months following your Termination Date; or

               (b)    such termination of service is due to your death, in which
event the option shall terminate on the earlier of the Expiration Date set forth
above or eighteen (18) months after your death; or

<PAGE>

               (c)    during any part of such three (3) month  period the option
is not  exercisable  solely  because of the  condition  set forth in paragraph 3
above,  in which event the option shall not  terminate  until the earlier of the
Expiration  Date set forth above or until it shall have been  exercisable for an
aggregate period of three (3) months after your Termination Date; or

               (d)    exercise of the option  within three (3) months after your
Termination Date would result in liability under section 16(b) of the Securities
Exchange Act of 1934, in which case the option will  terminate on the earlier of
(i) the  Expiration  Date set forth  above,  (ii) the tenth (10th) day after the
last date upon which  exercise  would result in such  liability or (iii) six (6)
months  and ten (10) days  after your  Termination  Date with the  Company or an
affiliate of the Company.

                   This option may be exercised  following your Termination Date
only  as to that  number  of  shares  as to  which  it was  exercisable  on your
Termination Date under the provisions of paragraph 1 of this option.

         6. Exercise. (a) This option may be exercised,  to the extent specified
above,  by delivering a notice of exercise (in a form designated by the Company)
together  with the exercise  price to the  Secretary of the Company,  or to such
other  person as the Company  may  designate,  during  regular  business  hours,
together  with such  additional  documents  as the Company  may then  reasonably
require.

               (b)    By exercising this option you agree that:

                      (i)       as a  precondition  to the  completion  of any
exercise of this  option,  the Company may require you to enter an  arrangement
providing for the cash payment by you to the Company of any tax  withholding
obligation of the Company arising by reason of: (1) the exercise of this option;
(2) the lapse of any substantial risk of forfeiture  to which the shares are
subject at the time of exercise;  or (3) the disposition of shares acquired upon
such exercise; and

                      (ii)      the Company (or a representative of the
underwriters)  may, in connection with the first  underwritten  registration
of the offering of any  securities of the Company  under  the Act,  require
that you not sell or  otherwise  transfer  or dispose of any shares of Common
Stock or other  securities of the Company during such  period  (not to exceed
one  hundred  eighty  (180)  days)  following  the effective  date (the
"Effective  Date") of the  registration  statement  of the Company  filed  under
the  Act as  may  be  requested  by  the  Company  or the representative  of the
underwriters.  You  further  agree that the  Company may impose  stop-transfer
instructions  with respect to  securities  subject to the foregoing restrictions
until the end of such period.

<PAGE>

         7. Covenant of Company.  During the term of this option,  the Company
shall keep  available at all times the number of shares of stock required to
satisfy the exercise of such option.

         8. Adjustment  Upon Changes in Stock.  (a) If any change is made in the
stock subject to this option  (through  merger,  consolidation,  reorganization,
recapitalization,  stock dividend,  dividend in property other than cash,  stock
split,  liquidating dividend,  combination of shares, exchange of shares, change
in  corporate  structure  or other  transaction  not  involving  the  receipt of
consideration by the Company), this option will be appropriately adjusted in the
type(s)  and number of  securities  and price per share of stock  subject to the
option.  Such  adjustments  shall  be  made  by  the  Board  of  Directors,  the
determination of which shall be final,  binding and conclusive.  (The conversion
of any  convertible  securities  of  the  Company  shall  not  be  treated  as a
"transaction not involving the receipt of consideration by the Company.")

                      (b)       In the event of:  (i) a merger or  consolidation
in which the Company is not the surviving corporation;  or (ii) a reverse merger
in which the Company is the surviving  corporation but the shares of the
Company's common stock  outstanding  immediately  preceding the merger are
converted by virtue of the merger  into other  property,  whether  in the form
of  securities,  cash or otherwise;  or (iii) a sale of all or  substantially
all of the  assets  of the Company,  then,  to the extent  permitted by
applicable  law: (1) any surviving corporation  shall  assume  this  option or
shall  substitute  a similar  option (including an option to acquire the same
consideration  paid to stockholders in the transaction  described in this
subparagraph  8(b)), if this option is still outstanding,  or (2) in the event
any surviving corporation refuses to assume or continue  this option,  or to
substitute  a similar  option for this option (if still  outstanding),  then
this option shall become fully vested and exercisable prior to such event and
shall  terminate  after such  acceleration of vesting if not exercised at or
prior to such corporate event. In the event of a dissolution or  liquidation
of the  Company,  this  option  (if  still  outstanding)  shall terminate if not
exercised prior to such event.

         9. Transferability.  This option is not transferable, except by will or
by the laws of descent and  distribution,  and is  exercisable  during your life
only by you. By delivering written notice to the Company, in a form satisfactory
to the Company, you may designate a third party who, in the event of your death,
shall thereafter be entitled to exercise this option.

         10.  Option Not a Service  Contract.  This option is not an  employment
contract  and  nothing  in this  option  shall be  deemed  to  create in any way
whatsoever any obligation on your part to continue in the employ of the Company,
or of the Company to continue  your  employment  with the Company.  In the event
that  this  option is  granted  to you in  connection  with the  performance  of
services  as a  consultant  or  director,  or in the 

<PAGE>

event  that this  option is granted to you in connection with the performance of
services as an employee and you  subsequently  perform  services as a consultant
or director,  references to employment,   employee  and  similar  terms  shall  
be  deemed  to  include  the performance  of services  as a  consultant  or a 
director,  as the case may be, provided,  however,  that no rights as an 
employee  shall arise by reason of the use of such terms.

         11. Notices.  Any notices provided for in this option shall be given in
writing and shall be deemed  effectively  given upon  receipt or, in the case of
notices  delivered  by the  Company to you,  five (5) days after  deposit in the
United States mail,  postage prepaid,  addressed to you at the address specified
below or at such other address as you hereafter  designate by written  notice to
the Company.

         12. Amendment.  This  option  may be  amended  by the  Board of
Directors  at any  time;  provided, however,  that any change that would
adversely  affect your rights in this option must first be approved by you in
writing before becoming effective.

         13. Administration.  This  option is subject  to all  interpretations,
amendments, rules and regulations which may from time to time be promulgated and
adopted by the Company.  This authority shall be exercised by the Board, or by a
committee  of one or more  members  of the  Board in the  event  that the  Board
delegates  its  authority  to a  committee.  The  Board,  in  exercise  of  this
authority, may correct any defect, omission or inconsistency in this option in a
manner and to the extent the Board shall deem  necessary  or  desirable  to make
this option fully effective. References to the Board shall mean the committee if
a committee has been appointed by the Board.  Any  interpretations,  amendments,
rules and  regulations  promulgated by the Board shall be final and binding upon
the  Company  and its  successors  in  interest  as well as you and your  heirs,
assigns, and other successors in interest.

<PAGE>

         14.  Rights as  Stockholder.  Neither  you nor any  person to whom this
option is transferred under paragraph 8 of this option shall be deemed to be the
holder of, or to have any of the rights of a holder with  respect to, any shares
subject  to  this  option  unless  and  until  such  person  has  satisfied  all
requirements for exercise of this option pursuant to its terms.
