                                  RISK FACTORS

         Certain matters  discussed in this  Prospectus may be forward-  looking
statements that are subject to risks and  uncertainties  that could cause actual
results to differ materially from those projected.  Such risks and uncertainties
include, but are not limited to, the risk factors set forth below. The following
important risk factors,  among others, may cause the Company's operating results
and/or financial position to be adversely affected from time to time:

         1.  Declining  demand or downward  pricing  pressure for the  Company's
products as a result of general or specific  economic  conditions,  governmental
budget decreases affecting the Department of Defense or NASA which would cause a
continued decrease in demand for AP, technological  advances and improvements or
new  competitive  products  causing a reduction or elimination of demand for AP,
sodium azide or Halotron,  the ability and desire of  purchasers  to  substitute
other  products for the  Company's  products  based upon  perceived  quality and
pricing, and the fact that perchlorate chemicals, sodium azide, Halotron and the
Company's   environmental   products  have  limited   applications   and  highly
concentrated customer bases.

         2.  Competitive  factors  including,  but not limited to, the Company's
limitations  respecting  financial  resources and its ability to compete against
companies with substantially greater resources, significant excess market supply
in the AP and  sodium  azide  markets  and the  development  or  penetration  of
competing new products,  particularly  in the propulsion,  airbag  inflation and
fire suppression businesses.

         3. Underutilization of the Company's manufacturing facilities resulting
in  production  inefficiencies  and  increased  costs,  the inability to recover
facility costs and reductions in margins.

         4. Difficulties in procuring raw materials, supplies, power and natural
gas used in the production of perchlorates, sodium azide or Halotron products or
used in the  engineering  and  assembly  process  for  environmental  protection
equipment products.

         5. The  Company's  ability to control the amount of operating  expenses
and/or  the impact of any  non-recurring  or unusual  items  resulting  from the
Company's  continuing  evaluation  of  its  strategies,   plans,  organizational
structure and asset valuations.

         6.  Risks  associated  with  the  Company's  real  estate   activities,
including,  but not  limited  to,  dependence  upon  the Las  Vegas  commercial,
industrial and residential  real estate markets,  changes in general or specific
economic conditions,


                                       -4-
<PAGE>
interest rate fluctuations affecting the availability and the cost of financing,
the  performance  of the managing  partner of the Gibson  Ranch L.L.P.  (Ventana
Canyon Joint Venture) and regulatory and  environmental  matters that may have a
negative impact on
sales.

         7. The effects of, and changes in, trade, monetary and fiscal policies,
laws and  regulations and other  activities of governments,  agencies or similar
organizations,   including,  but  not  limited  to,  environmental,  safety  and
transportation issues.

         8. The cost  and  effects  of  legal  and  administrative  proceedings,
settlements and investigations, particularly those described in the "Commitments
and Contingencies" note to the Company's financial  statements  contained in its
most  current  periodic  SEC  report,  and claims made by or against the Company
relative to patents or property rights.

         9. The adoption of new, or changes in existing, accounting policies and
practices.

                               GENERAL INFORMATION

         The Company,  through its indirect  subsidiary Western  Electrochemical
Company ("WECCO"), is engaged in the production of specialty chemical,  ammonium
perchlorate  ("AP"),  for the aerospace  and national  defense  industries.  The
Company is one of two domestic  manufacturers  of AP, which is used primarily as
an oxidizing  agent in composite solid  propellants for rockets,  booster motors
and missiles.  The  Company's  customers  for AP are  primarily  contractors  in
programs of the National Aeronautics and Space  Administration  ("NASA") and the
Department of Defense  ("DDD"),  and companies  providing  commercial  satellite
launch services. These NASA and DDD contractors are engaged in space exploration
projects  such as the Space  Shuttle  Program and in the  production  of defense
systems.  Other  customers  for the  Company's AP include  aerospace and defense
agencies of foreign countries.

         In  May  1994,  the  Company  and  its  principal   customer,   Thiokol
Corporation  ("Thiokol"),  executed an amendment (the  "Amendment")  to the 1989
Advance  Agreement.  The  1989  Advance  Agreement  represents  one  of  certain
agreements  related to the sale of AP. The Company and Thiokol  previously had a
dispute over the interpretation of these agreements. See Legal Proceedings. As a
result of a  significant  change in the  demand for AP,  during the fiscal  year
ended  September  30,  1994,  the Company  recognized  an  impairment  charge of
$39,401,000 related to WECCO's fixed assets.

         The  Company is a party to  agreements  with  Dynamit  Nobel  A.G.,  of
Germany  ("Dynamit  Nobel") relating to the production and sale of sodium azide,
the principal  component of the gas generant used in automotive  airbag systems.
Dynamit Nobel licensed to the


                                       -5-
<PAGE>
Company, on an exclusive basis for the North American market, its technology and
know-how in the  production  of sodium  azide,  and has provided  the  technical
support for the design,  construction and start-up of the Company's sodium azide
facility.  Funding for the facility was partially  provided by means of the sale
of $40,000,000  principal amount of noncallable  subordinated secured notes (the
"Azide Notes") to a major state public  employee  retirement  fund and a leading
investment  management company. The Company commenced commercial sales of sodium
azide in fiscal 1994.

         In  February  1992,  the  Company  acquired  (by  exercise of an option
previously  granted to it) the worldwide rights of Halotron,  a fire suppression
system that includes chemical compounds and application  technology  intended to
replace  halons,  which have been found to be ozone  layer-depleting  chemicals.
Halotron has applications as a fire suppression  agent for military,  commercial
and industrial  uses. The Company has completed the  construction of a plant for
the production of certain  Halotron  products.  The Company  expects to become a
qualified  supplier for military,  commercial  and industrial  applications  for
Halotron products,  although there can be no assurance in that regard. As of the
date hereof, the Company's sales of Halotron products have not been significant.

         The Company is also  engaged in the  development  of real estate and in
the production of environmental protection and waste water treatment equipment.

         The Company's  principal  executive  offices are located at 3770 Howard
Hughes  Parkway,  Suite 300, Las Vegas,  Nevada 89109.  The Company's  telephone
number at such location is (702) 735- 2200.

                                 USE OF PROCEEDS

         The Shares  offered  hereby  were or will be  purchased  by the Selling
Shareholders  upon exercise of options  granted to them and will be sold for the
account of the Selling Shareholders. The Company will receive the exercise price
of the options when exercised by the holders thereof. Such proceeds will be used
for working capital purposes by the Company. The Company will not receive any of
the  proceeds  from  the  reoffer  and  resale  of the  Shares  by  the  Selling
Shareholders.

                              SELLING SHAREHOLDERS

         This  Prospectus  relates to the reoffer and resale of Shares issued or
that may be issued under the 1982 Plan,  the 1988  Non-Qualified  Plan, the 1988
Incentive Plan and the 1991 Plan to those Selling Shareholders who are deemed to

ITEM 6.  INDEMNIFICATION OF OFFICERS AND DIRECTORS

         The  certificate of  incorporation  and by-laws of the Company  provide
that the Company  shall  indemnify to the extent  permitted by Delaware law, any
person whom it may indemnify thereunder,


                                       -9-
<PAGE>
including  directors,  officers,  employees  and  agents  of  the  Company.  The
pertinent   section  of  Delaware   law  is  set  forth  below  in  full.   Such
indemnification  (other than as ordered by a court) shall be made by the Company
only upon a determination  that  indemnification  is proper in the circumstances
because the individual met the applicable standard of conduct. Advances for such
indemnification may be made pending such determination. Such determination shall
be made by a majority vote of a quorum consisting of disinterested directors, or
by independent  legal counsel or by the stockholders.  In addition,  the Company
has  amended  its  certificate  of  incorporation  to  eliminate,  to the extent
permitted by Delaware  law,  personal  liability of directors to the Company and
its stockholders for monetary damages for breach of fiduciary duty as directors.

         The Company  also  maintains a directors  and  officers  insurance  and
company  reimbursement policy. The policy insures directors and officers against
unindemnified  loss arising from certain  wrongful acts in their  capacities and
reimburses  the  Company  for such  loss for  which  the  Company  has  lawfully
indemnified the directors and officers.  The policy contains various exclusions,
no one of which relates to the offering hereunder.

         Section  145  of the  Delaware  General  Corporation  Law  provides  as
follows:

                  (a) A  corporation  may  indemnify  any person who was or is a
         party or is threatened to be made a party to any threatened, pending or
         completed  action,  suit  or  proceeding,   whether  civil,   criminal,
         administrative  or investigative  (other than action by or in the right
         of the corporation) by reason of the fact that he is or was a director,
         officer, employee or agent of the corporation,  or is or was serving at
         the  request of the  corporation  as a director,  officer,  employee or
         agent of another  corporation,  partnership,  joint  venture,  trust or
         other  enterprise,   against  expenses  (including   attorneys'  fees),
         judgments, fines and amounts paid in settlement actually and reasonably
         incurred by him in connection  with such action,  suit or proceeding if
         he acted in good faith and in a manner he reasonably  believed to be in
         or not opposed to the best  interests  of the  corporation,  and,  with
         respect to any criminal action or proceeding,  had no reasonable  cause
         to believe his conduct was  unlawful.  The  termination  of any action,
         suit or proceeding by judgment, order, settlement,  conviction, or upon
         a plea of nolo  contendere  or its  equivalent,  shall not,  of itself,
         create a presumption that the person did not act in good faith and in a
         manner which he reasonably believed to be in or not opposed to the best
         interests of the corporation,  and, with respect to any criminal action
         or


                                      -10-
<PAGE>
         proceeding,  had  reasonable  cause to  believe  that his  conduct  was
         unlawful.

                  (b) A  corporation  may  indemnify  any person who was or is a
         party or is threatened to be made a party to any threatened, pending or
         completed  action  or suit by or in the  right  of the  corporation  to
         procure a judgment in its favor by reason of the fact that he is or was
         a director, officer, employee or agent of the corporation, or is or was
         serving  at the  request of the  corporation  as a  director,  officer,
         employee or agent of another corporation,  partnership,  joint venture,
         trust or other enterprise against expenses (including  attorneys' fees)
         actually and reasonably  incurred by him in connection with the defense
         or settlement of such action or suit if he acted in good faith and in a
         manner  he  reasonably  believed  to be in or not  opposed  to the best
         interests of the corporation and except that no  indemnification  shall
         be made in  respect  of any  claim,  issue or matter  as to which  such
         person shall have been adjudged to be liable to the corporation  unless
         and only to the extent that the Court of Chancery or the court in which
         such action or suit was brought shall determine upon application  that,
         despite  the   adjudication  of  liability  but  in  view  of  all  the
         circumstances  of the  case,  such  person  is  fairly  and  reasonably
         entitled to indemnity for such expenses  which the Court of Chancery or
         such other court shall deem proper.

                  (c) To the extent that a director,  officer, employee or agent
         of a  corporation  has been  successful  on the merits or  otherwise in
         defense of any action,  suit or proceeding  referred to in  subsections
         (a) and (b) of this  section,  or in  defense  of any  claim,  issue or
         matter therein,  he shall be indemnified  against  expenses  (including
         attorneys' fees) actually and reasonably  incurred by him in connection
         therewith.

                  (d) Any indemnification  under subsections (a) and (b) of this
         section  (unless  ordered by a court) shall be made by the  corporation
         only as  authorized  in the  specific  case upon a  determination  that
         indemnification of the director,  officer,  employee or agent is proper
         in the  circumstances  because he has met the  applicable  standard  of
         conduct  set forth in  subsections  (a) and (b) of this  section.  Such
         determination shall be made (1) by the board of directors by a majority
         vote of a quorum  consisting  of directors who were not parties to such
         action, suit or proceeding,  or (2) if such a quorum is not obtainable,
         or, even if obtainable a quorum of disinterested  directors so directs,
         by  independent  legal  counsel  in a  written  opinion,  or (3) by the
         stockholders.

                  (e) Expenses incurred by an officer or director in defending a
         civil  or  criminal  action,  suit  or  proceeding  may be  paid by the
         corporation in advance of the final disposition or such action, suit or
         proceeding  upon  receipt  of an  undertaking  by or on  behalf of such
         director  or  officer to repay such  amount if it shall  ultimately  be
         determined that he is not entitled to be indemnified by the corporation
         as  authorized  in  this  section.  Such  expenses  incurred  by  other
         employees  and agents may be paid upon such  terms and  conditions,  if
         any, as the board of directors deems appropriate.

                  (f) The  indemnification  and advancement of expenses provided
         by, or granted pursuant to, the other subsections of this section shall
         not be deemed  exclusive  of any other  rights to which  those  seeking
         indemnification  or  advancement  of expenses may be entitled under any
         bylaw,  agreement,  vote of stockholders or disinterested  directors or
         otherwise,  both as to action in his official capacity and as to action
         in another capacity while holding such office.

                  (g) A  corporation  shall have power to purchase  and maintain
         insurance  on behalf of any person who is or was a  director,  officer,
         employee  or  agent of the  corporation,  or is or was  serving  at the
         request of the corporation as a director, officer, employee or agent of
         another  corporation,   partnership,  joint  venture,  trust  or  other
         enterprise  against any liability  asserted against him and incurred by
         him in any such capacity, or arising out of his status as such, whether
         or not the  corporation  would have the power to indemnify  him against
         such liability under this section.

                  (h)  For  purposes  of  this   section,   references  to  "the
         corporation" shall include,  in addition to the resulting  corporation,
         any   constituent   corporation   (including   any   constituent  of  a
         constituent)  absorbed  in a  consolidation  or  merger  which,  if its
         separate  existence  had  continued,  would  have  had  the  power  and
         authority  to  indemnify  its  directors,  officers,  and  employees or
         agents, so that any person who is or was a director,  officer, employee
         or agent of such constituent  corporation,  or is or was serving at the
         request  of  such  constituent  corporation  as  a  director,  officer,
         employee or agent of another corporation,  partnership,  joint venture,
         trust or other enterprise,  shall stand in the same position under this
         section with respect to the  resulting or surviving  corporation  as he
         would have with respect to such constituent corporation if its separate
         existence had continued.

                  (i)  For  purposes  of  this  section,  references  to  "other
         enterprises"  shall  include  employee  benefit  plans;  references  to
         "fines" shall include any such excise taxes


                                      -12-
<PAGE>
         assessed on a person with respect to any  employee  benefit  plan;  and
         references to "serving at the request of the corporation" shall include
         any  service  as  a  director,   officer,  employee  or  agent  of  the
         corporation  which  imposes  duties on, or involves  services  by, such
         director,  officer,  employee,  or agent with  respect to any  employee
         benefit plan, its participants or beneficiaries; and a person who acted
         in good faith and in a manner reasonably believed to be in the interest
         of the  participants  and  beneficiaries  of any employee  benefit plan
         shall be  deemed to have  acted in a manner  "not  opposed  to the best
         interests of the corporation" as referred to in this section.

                  (j) The  indemnification  and advancement of expenses provided
         by, or granted  pursuant  to,  this  section  shall,  unless  otherwise
         provided when  authorized or ratified,  continue as to a person who has
         ceased to be a director,  officer, employee or agent and shall inure to
         the  benefit  of the  heirs,  executors  and  administrators  of such a
         person.

         The Company has purchased director and officer liability  insurance for
its directors and officers.

                  of  1933,  each  filing  of  the  registrant's  annual  report
                  pursuant to Section 13(a) or 15(d) of the Securities  Exchange
                  Act of 1934 (and, where applicable, each filing of an employee
                  benefit plan's annual report  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

<PAGE>
                  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  Securities  Act of 1933 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 a
                  controlling  precedent,  submit  to  a  court  of  appropriate
                  jurisdiction the question whether such  indemnification  by it
                  is against public policy as expressed in the Securities Act of
                  1933 and will be  governed by the final  adjudication  of such
                  issue.

accordance  with its terms,  by delivery of a written  notice of exercise to the
Company and payment of the full purchase price of the Shares being purchased. An

                  6.5 PAYMENT.  The Purchase Price of Shares purchased  pursuant
to an Option or portion thereof,  may be paid in United States Dollars,  in cash
or by check, bank draft or money order payable to the Company.

                  6.6 TRANSFERABILITY. No Option shall be transferable otherwise
than by will or the laws of descent  and  distribution,  and an Option  shall be
exercisable  during  the  Eligible  Director's  lifetime  only  by the  Eligible
Director, his guardian or legal representative.

                  6.7  TERMINATION  OF MEMBERSHIP  ON THE BOARD.  If an Eligible
Director's  membership on the Board terminates for any reason,  an Option vested
on the  date of  termination  may be  exercised  in whole or in part at any time
within two (2) years after the date of such  termination (but in no event  after
the term of the Option expires) and shall thereafter terminate.

                                   ARTICLE VII

                        GOVERNMENT AND OTHER REGULATIONS

                  7.1 DELIVERY OF SHARES. The obligation of the Company to issue
or transfer and deliver  Shares for  exercised  Options  under the Plan shall be
subject to all applicable laws,  regulations,  rules, orders and approvals which
shall then be in effect.

                  7.2  HOLDING OF STOCK  AFTER  EXERCISE  OF OPTION.  The Option
Agreement  shall provide that the Eligible  Director,  by accepting such Option,
represents and agrees,  for the Eligible Director and his permitted  transferees
hereunder that none of the Shares purchased upon exercise of the Option shall be
acquired  with a view to any sale,  transfer  or  distribution  of the Shares in
violation of the  Securities  Act of 1933, as amended (the "Act") and the person
exercising an Option shall furnish evidence satisfactory to that Company to that
effect,  including  an  indemnification  of  the  Company  in the  event  of any
violation of the Act by such person.  Notwithstanding the foregoing, the Company
in its sole  discretion  may  register  under the Act the Shares  issuable  upon
exercise of the Options under the Plan.

                                  ARTICLE VIII

                                 WITHHOLDING TAX

                  The  Company  may  in  its  discretion,  require  an  Eligible
Director to pay to the  Company,  at the time of exercise of an Option an amount
that the Company deems necessary to satisfy its obligations to withhold federal,
state or local  income  or other  taxes  (which  for  purposes  of this  Article
includes  an Eligible  Director's  FICA  obligation)  incurred by reason of such
exercise. When the exercise of an Option does not give rise to the obligation to
withhold  federal income taxes on the date of exercise,  the Company may, in its
discretion,  require an Eligible  Director to place Shares  purchased  under the
Option in escrow  for the  benefit  of the  Company  until  such time as federal
income  tax  withholding  is  required  on  amounts  included  in  the  Eligible
Director's gross income as a result of the exercise of an Option.  At such time,
the Company,  in its discretion,  may require an Eligible Director to pay to the
Company an amount that the Company deems  necessary to satisfy its obligation to
withhold federal, state or local taxes incurred by reason of the exercise of the
Option,  in which case the Shares will be released from escrow upon such payment
by an Eligible Director.

                                   ARTICLE IX

                                   ADJUSTMENTS

                  9.1 PROPORTIONATE  ADJUSTMENTS.  If the outstanding Shares are
increased,  decreased, changed into or exchanged into a different number or kind
of Shares or securities of the Company through reorganization, recapitalization,
reclassification,  stock  dividend,  stock split,  reverse  stock split or other
similar transaction,  an appropriate and proportionate  adjustment shall be made
to the  maximum  number  and kind of Shares as to which  Options  may be granted
under this  Plan.  A  corresponding  adjustment  changing  the number or kind of
Shares allocated to unexercised  Options or portions  thereof,  which shall have
been  granted  prior to any  such  change,  shall  likewise  be  made.  Any such
adjustment  in the  outstanding  Options  shall be made  without  change  in the
Purchase  Price  applicable  to the  unexercised  portion of the  Option  with a
corresponding  adjustment  in the  Exercise  Price of the Shares  covered by the
Option.  Notwithstanding  the  foregoing,  there shall be no adjustment  for the
issuance  of Shares on  conversion  of notes,  preferred  stock or  exercise  of
warrants or Shares issued by the Board for such consideration as the Board deems
appropriate.

                  9.2  DISSOLUTION  OR  LIQUIDATION.  Notwithstanding  any other
provision hereof,  upon the dissolution or liquidation of the Company, or upon a
reorganization,  merger  or  consolidation  of the  Company  with  one  or  more
corporations as a result of which


                                       -5-

the Company is not the surviving  corporation,  or upon a sale of  substantially
all of the assets or property or more than 80% of the then outstanding Shares of
the  Company to another  corporation,  the Company  shall give to each  Eligible
Director  at the time of  adoption  of the plan  for  liquidation,  dissolution,
merger or sale either (1) a reasonable time thereafter  within which to exercise
the Option  prior to the  effective  date of such  liquidation  or  dissolution,
merger or sale,  or (2) the right to  exercise  the  Option as to an  equivalent
number of Shares of stock of the corporation succeeding the Company or acquiring
its business by reason of such liquidation,  dissolution,  merger, consolidation
or reorganization.

                  than as provided in Article V.

                  10.2  TERMINATION.  The  Board  at any  time  may  suspend  or
terminate this Plan. This Plan, unless sooner terminated, shall terminate on the
fifth (5th)  anniversary of its adoption by the Board.  No Option may be granted
under this Plan while this Plan is suspended or after it is terminated.

                  10.3  HOLDER  OF  CONSENT.   No   amendment,   suspension   or
termination  of the Plan  shall,  without  the consent of the holder of Options,
alter or impair any rights or obligations under any Option  theretofore  granted
under the Plan.

of the  State of  Delaware.  The  Plan  and all  Options  which  may be  granted
hereunder and all matters  related  thereto,  shall be governed by and construed

                        3.03 TIME FOR EXERCISE. The Option hereby granted to the
Optionee shall be exercisable at the following times:

                        With respect to Two Thousand Five Hundred (2,500) shares
                of common stock, the Option shall be exercisable on or after the
                date of this Option Agreement;

                        With respect to an additional  Two Thousand Five Hundred
                (2,500) shares of common stock,  the Option shall be exercisable
                on or after one year after the date of this Option Agreement.

The Option granted  hereunder  shall be  exercisable  for a period of five years
after such Option first becomes  exercisable  in  accordance  with the foregoing
provisions  of this  Section  3.03,  unless  the  period of  exercise  is sooner
terminated  in accordance  with the  provisions  of this Option  Agreement.  The
Optionee shall have no right whatsoever to exercise the Option except during the
times provided above.

                        3.04  RESTRICTIONS ON TRANSFERS AND ENCUMBRANCE.  During
the lifetime of the  Optionee,  the Option  granted  hereunder  may not be sold,
pledged, assigned, hypothecated, encumbered or transferred in any manner, either
voluntarily or involuntarily,  by operation of law or otherwise,  except by will
or by applicable laws of descent and  distribution,  and may be exercised during
an  Optionee's  lifetime  only  by  the  Optionee  or by  the  Optionee's  legal
representative. Any Option that has not expired as of the date of the Optionee's
death may be exercised after the Optionee's  death only by the person or persons
to whom the Optionee's  interest in the Option have passed by will, by the terms
of a family trust  agreement or other like  instrument or by applicable  laws of
descent and distribution.

                        3.05 EXERCISE  AFTER DEATH OR  DISABILITY.  In the event
that the Optionee dies or becomes Disabled while in, or within ninety days after
ceasing to be a Director of the Company,  the Optionee  shall be treated for all
purposes  of  this  Agreement  as  continuing  in the  service  of  the  Company

III but for the Optionee's death or Disability.

                        3.06  EXERCISE  SUBJECT TO  SERVICE.  The  Optionee  may
exercise  the  Option  granted  hereunder  only  if the  Optionee  has  remained

which the Option sought to be exercised was granted to such Optionee,  through a
date that is not more than two  years  prior to the date on which the  Option is
sought to be  exercised.  The  provisions  of this Section shall not prevent the
individual or entity to whom an Option has passed by will or by applicable  laws
of descent and  distribution  after the death of an Optionee from exercising the
Option  within  the  period  of  time  during  which  the  Option  is  otherwise
exercisable  under the  provisions of this Option  Agreement,  if the Option was
exercisable under all provisions of this Agreement  (including the provisions of
this Section 3.06) by the Optionee as of the date of the Optionee's death.

                             PROCEDURE FOR EXERCISE

                        4.01 TIME FOR  EXERCISE.  Subject to the  provisions  of
this Article IV, the Option granted  hereunder shall be exercisable  only during
the times provided in this Option Agreement.

                        4.02 EXERCISE UPON CORPORATE CAPITAL TRANSACTION. In the
event  that the  Company,  its  shareholders,  or  both,  enter  into a  written
agreement to dispose of all or  substantially  all of the assets or Common Stock
of the  Company  by  means  of a sale,  merger,  consolidation,  reorganization,
liquidation  or similar  transaction  (other  than a  reorganization,  merger or
consolidation  effected  solely  to  change  the  Company's  name  or  state  of
incorporation), the Option issued pursuant to this Option Agreement shall become
immediately  exercisable,  whether or not such Option was  exercisable  prior to
such  event,  during  the  period of time  beginning  with the date on which the
Company  agrees in  writing to enter  into such  transaction,  and ending on the
earlier of the date the Option would otherwise have expired or the date on which
the transaction is consummated.  Upon the consummation of the  transaction,  any
unexercised  portion of the Option issued hereunder shall terminate and cease to
be effective. In the event that the agreement to enter into any such transaction
is terminated, all unexercised portions of the Option shall revert to the status
they had before the Company  agreed to enter into the  transaction  in question.
Any exercise of Option made before the  agreement to enter into the  transaction
was terminated  shall remain  effective  after the termination of the agreement,
notwithstanding  that the Option may have become exercisable solely by reason of
the Company entering into the agreement.

                        4.03  WITHHOLDING OF TAXES.  The Optionee  hereby agrees
that the Company may, if it elects to do so, withhold  federal,  state and other
taxes  attributable to taxable income realized by the Optionee upon the exercise
of Option from any compensation or other payment payable to such Optionee by the
Company.

                        4.04 EXERCISE. Subject to all other terms and provisions
of this Option  Agreement,  the Option granted  hereunder  shall be deemed to be
exercised  when written  notice of exercise has been given to the Company by the
Optionee or other  person  entitled to exercise  the Option and full  payment in
cash or cash equivalents (or with Common Stock of the Company if approved by the
Committee  pursuant to Section 4.07) for the shares of Common Stock with respect
to which  the  Option is  exercised  has been  received  by the  Company.  Until
certificates  have been  issued  for the  number of  Shares  represented  by the
exercise of the Option,  the  Optionee  shall have no right to vote,  to receive
dividends,  or other  right as a  stockholder  with  respect to shares of Common
Stock  purchased  through  the  exercise  of the  Option.  Except as provided in
Section 5.01 hereof,  no adjustments shall be made for dividends or other rights
declared or paid with  respect to stock  acquired  through  the  exercise of the
Option  for  which  the  record  date is  prior  to the  date  on  which a stock
certificate for such shares is issued.

                        4.05 EXERCISE IN INSTALLMENTS.  Subject to Section 3.03,
the Optionee may exercise the Option in installments, but only in units of whole
shares of the Common Stock of the Company.

<PAGE>
                        4.06 ISSUANCE OF  CERTIFICATES.  As soon as  practicable
after the Option has been  exercised in accordance  with the  provisions of this
Option  Agreement,  the Company  shall,  without  transfer or issue tax or other
charge to the Optionee, deliver to the Optionee at the principal business office
of  the  Company,  or at  such  other  place  as  may  be  agreed,  certificates
representing  the  number of shares of Common  Stock as to which the  Option has
been  exercised.  The Company  may,  however,  postpone  the time of delivery of
certificates  for  such  period  of  time as the  Company  may  determine  to be
necessary for it with reasonable diligence to comply with any applicable listing
requirements of any national or regional  securities  exchange,  of the National
Association  of  Securities  Dealers,  Inc.,  or  with  any  law  or  regulation
applicable to the issuance or delivery of shares of the Company's Common Stock.


                                    ARTICLE V

                     RESTRICTIONS AND ADDITIONAL PROVISIONS

                        5.01 ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.  If the
number of outstanding  shares of the Common Stock of the Company is increased or
decreased,  or if the Common Stock of the Company  underlying the Option granted
pursuant to the provisions of this Option Agreement is changed into or exchanged
for a different  number or kind of shares or securities of the Company through a
reorganization,  merger,  recapitalization,  reclassification,  stock  dividend,
stock split or reverse stock split, an appropriate and proportionate  adjustment
shall be made by the  Committee  in the  terms  and  conditions  of the  Options
granted pursuant hereto,  including the Exercise Price of the Option;  provided,
however,  that no such  adjustment  need be made if,  upon the  advice  of legal
counsel to the Company,  the Committee determines that any such adjustment could
result in the  recognition  of federal  taxable  income by the  Optionee,  or by
holders of Common Stock or other securities of the Company.

                        5.02  RESERVATION OF SHARES OF COMMON STOCK. The Company
shall,  at all times  during the periods of time during  which the Option may be
exercised  hereunder,  reserve and keep available for issuance to the Optionee a
number of shares of its Common Stock  sufficient to satisfy all  obligations  of
the Company hereunder.

                        5.03  RESTRICTIONS  ON ISSUANCE  OF SHARES.  The Company
shall use its best  efforts to seek and to obtain  from  appropriate  regulatory
agencies any requisite  authorization  in order to issue and sell such number of
shares of its Common Stock as shall be sufficient to satisfy the  obligations of
the  Company  under  this  Agreement.  The  inability  of the  Company to obtain
authorization  deemed to be  necessary  by the  Company's  legal  counsel to the
lawful  issuance  and sale of any shares of the  Company's  Common  Stock  shall
relieve  the  Company of any  liability  for the  nonissuance  or nonsale of any
Common Stock as to which the requisite approval or authorization  shall not have
been obtained.

                        5.04  REPRESENTATIONS AND WARRANTIES.  As a condition to
the exercise of the Option  granted  hereunder,  the  Committee  may require the
person  exercising the Option to make any  representations  or warranties to the
Company  that legal  counsel to the  Company  may  determine  to be  required or
advisable under any applicable law or regulation, including without


                                       6
<PAGE>
limitation a representation and warranty that the shares of the Company's Common
Stock being  acquired are being  acquired  only for  investment  and without any
present intention or view to sell or distribute any such shares.

                        5.05  OPTIONEE  RIGHTS.  No provision of this  Agreement
shall be  deemed to  constitute  a  condition  of the  service  or status of any
Director.  No provision of this Option  Agreement shall be deemed to give to the
Optionee  any right to be  retained  in the  service  of the  Company  or of any
Subsidiary  Corporation  in any  capacity  (whether  as an  employee,  Director,
independent contractor or otherwise),  or to interfere in any way with the right
of the  Company  and its  Subsidiary  Corporations  at any  time to  remove  any
Director,  or to discontinue using the services of any individual.  The Optionee
shall have no right or interest in any share of the Company's Common Stock prior
to exercise of the Option, except as provided in this Option Agreement.

                        5.06   LEGENDS   ON  STOCK   CERTIFICATES.   Unless   an
appropriate  registration  statement is on file and effective  with  appropriate

                  Re:  American Pacific Corporation - Registration
                       Statement on Form S-8 filed August 28, 1996
                       -------------------------------------------
Dear Sir or Madam:

                  We are counsel to American Pacific Corporation ("Registrant").
We furnish this opinion in  connection  with the  above-referenced  Registration
Statement relating to 118,000 shares of Common Stock of the Registrant  issuable
upon the exercise of  outstanding  stock options  granted or to be granted under
certain stock option plans (the  "Securities")  as set forth in the Registration
Statement.

                  In furnishing our opinion, we have examined the Certificate of
Incorporation and the By-Laws of the Registrant,  and such other instruments and
documents,  including  the minutes of the  meetings of the Board of Directors of
Registrant,  as well as  certificates  of public  officials  and officers of the
Registrant,  as we have  deemed  relevant  and  necessary  as the  basis for our
opinion expressed herein. We have examined originals or certified,  conformed or
photostatic  copies  of all  documents,  the  authenticity  of  which  has  been
established to our satisfaction.  In all such examinations,  we have assumed the
genuineness  of all  signatures  on original and  certified  documents,  and the
conformity to executed  documents of all  unexecuted  copies  submitted to us as
conformed or photostatic copies.

                  Based  upon  the  foregoing,  we are of the  opinion  that the
Securities have been duly authorized and will be legally issued,  fully paid and
non-assessable;  subject,  however, to receipt by the Registrant of the exercise
price for the options.

                  We hereby  consent to use of this opinion in the  Registration
Statement and Prospectus, and to the use of our name in the Prospectus under the
caption "Legal Matters".

                  We advise you that Victor M. Rosenzweig, a member of our Firm,
is a Director  of the  Registrant  and holds  1,400  shares of Common  Stock and
options to purchase 5,000 shares of Common Stock.

                                          Very truly yours,


                                          OLSHAN GRUNDMAN FROME & ROSENZWEIG LLP

INDEPENDENT AUDITORS' CONSENT
