                           TO BE HELD FEBRUARY 1, 1999


To the Shareholders of OSHKOSH TRUCK CORPORATION:

         Notice is hereby  given that the  Annual  Meeting  of  Shareholders  of
Oshkosh Truck Corporation, a Wisconsin corporation, 2307 Oregon Street, P.O. Box

         Only  shareholders  of record at the close of business on December  16,
1998,  will  be  entitled  to  notice  of and to  vote  at the  meeting  and any
adjournment thereof.

         A copy of the Annual  Report of the  company  for the fiscal year ended

         If you will be unable to be present in person at the meeting and desire

                                            By order of the Board of Directors,



                                            TIMOTHY M. DEMPSEY, Secretary
                                            OSHKOSH TRUCK CORPORATION
Oshkosh, Wisconsin
December 23, 1998







                            OSHKOSH TRUCK CORPORATION

               Proxy Statement for Annual Meeting of Shareholders
                         To be Held on February 1, 1999

         This  statement  is  furnished  on  or  about  December  30,  1998,  in
connection with the solicitation of proxies by the Board of Directors of Oshkosh
Truck Corporation,  2307 Oregon Street, P.O. Box 2566, Oshkosh,  Wisconsin 54903
(the "company"), to be used at the Annual Meeting of Shareholders of the company
to be held on Monday,  February 1, 1999, at 10:00 o'clock in the forenoon at the
Experimental   Aircraft   Association  Museum,  3000  Poberezny  Road,  Oshkosh,
Wisconsin,  for the  purposes  set  forth in the  accompanying  Notice of Annual
Meeting of Shareholders.

         Execution  of a proxy given in response to this  solicitation  will not
affect a  shareholder's  right to  attend  the  meeting  and to vote in  person.
Presence  at the  meeting  of a  shareholder  who has signed a proxy does not in
itself  revoke the proxy.  Any  shareholder  giving a proxy may revoke it at any
time before it is exercised by giving  notice  thereof to the Board of Directors
in writing or in open  meeting.  Unless so revoked,  the shares  represented  by
proxies  received by the Board of Directors  will be voted at the meeting or any
adjournments  thereof.  Where a  shareholder  specifies  a choice  by means of a
ballot  provided in the proxy,  the shares will be voted in accordance with such
specification.

         Only  holders  of shares of Class A Common  Stock,  $.01 par value (the
"Class A Common Stock"),  and Common Stock, $.01 par value (the "Common Stock"),
on December 16, 1998, are entitled to vote at the Annual Meeting.  On that date,
the company had  outstanding  and  entitled  to vote  296,756  shares of Class A
Common Stock and 8,124,745 shares of Common Stock.  Currently,  the company does
not have a shareholder rights plan. However, the company's Board of Directors is
considering the adoption of such a plan. The terms of any plan that the Board of
Directors may adopt are not known at this time.  However,  any rights plan could
have the  effect of making  it more  difficult  for any  person to  acquire  the
company or acquire control of the company.

         There are separate proxy cards for the Class A Common Stock (white) and
the Common  Stock  (green).  Enclosed for holders of shares of only one class of
stock is the  appropriate  proxy card.  Enclosed  for holders of both classes of
stock are both  proxy  cards;  each  proxy  card must be  completed,  signed and
returned for shares of each class to be represented at the meeting.

                              ELECTION OF DIRECTORS

         The  Board of  Directors  of the  company  currently  consists  of nine
members,  each of whom is elected  each year to serve for a term of one year and
until his or her successor is elected.  Under the company's Restated Articles of
Incorporation,  as amended,  holders of shares of Common Stock have the right to
elect as a class 25% of the entire Board of  Directors  of the  company.  At the
Annual  Meeting,  nine directors  will be elected;  holders of shares of Class A
Common Stock will elect seven  directors,  and holders of shares of Common Stock
will elect two directors.  Unless  otherwise  revoked,  proxies  received by the
Board of Directors  with  authority to vote in the election of directors will be
voted at the Annual  Meeting for the election for one-year  terms of each of the
nominees  listed on the  following  page.  Because  directors  are  elected by a
plurality  of the  votes  cast  (assuming  a quorum  is  present  at the  Annual
Meeting),  any shares not voted,  whether due to abstentions or broker nonvotes,
have no impact on the election of directors  except to the extent the failure to
vote for an individual results in another  individual  receiving a larger number
of votes.

         In the  event  that  any of the  nominees  should  fail  to  stand  for
election,  the persons named in the form of proxy intend to vote for  substitute
nominees.

         Certain  information  as of November  18,  1998,  with  respect to each
nominee is set forth on the next page.

the Internal  Revenue Code. In 1998 Mr.  Hollowell also received medical expense
reimbursements in the sum of $3,983.

         (3) Mr. Goodson was Chairman and Chief Executive Officer of the company
for that part of fiscal  year 1998  ending on October 9, 1997.  Amount  shown as
"All Other  Compensation"  for Mr. Goodson reflects  payments under a separation
agreement. See Agreements with Named Executive Officers, on page 9.

         (1) The options reflected in the table (which are non-qualified options
for purposes of the  Internal  Revenue  Code) vest  ratably over the  three-year
period from the date of grant.

         (2) This presentation is intended to disclose the potential value which
would  accrue to the  optionee  if the option were  exercised  the day before it
would expire and if the per share value had appreciated at the compounded annual
rate indicated in each column.  The assumed rates of  appreciation of 5% and 10%
are prescribed by the rules of the Securities and Exchange Commission  regarding
disclosure of executive  compensation.  The assumed annual rates of appreciation
are not intended to forecast possible future appreciation,  if any, with respect
to the price of the Common Stock.

         (3) The options reflected in the table which have an expiration date of
10/20/08  will not be effective  unless  holders of Class A Common Stock approve
the amended 1990 Plan.

- -----------------

         (1) The annual  benefits  shown in the table are based on final average
compensation  listed in the  appropriate  compensation  row and years of service
listed in the  appropriate  column.  The  amounts  shown  here are  subject to a
reduction equal to 45% of the Primary Social Security  Benefit payable at age 65
reduced by 1/30th for each year of service less than 30.

         (2) As of March 1, 1994,  for this plan,  IRS  regulations  lowered the
amount of  compensation  allowed to be includable in benefit  calculations  from
$235,840  to  $150,000.  As of March 1,  1997,  this  amount  was  increased  to
$160,000.  Accrued  benefits  calculated  as of February 28, 1994, at the higher
limit have been grandfathered.


         Under the Pension Plan, a salaried employee is entitled to receive upon
retirement  at  age 65 a  monthly  benefit  equal  to  50%  of  average  monthly
compensation  less 45% of primary  social  security,  reduced by 1/30th for each
benefit accrual year of service less than 30, or certain actuarially  equivalent
benefits.  Average  monthly  compensation  is based on the  average  of the five
highest  consecutive  years of  earnings  (excluding  bonuses  and  subject to a
maximum  of  $160,000  per  calendar  year)  prior to the  participant's  normal
retirement age or other date of  termination.  One thousand  hours  constitute a
year of service.  An employee  who has reached the age of 55 with a minimum of 5
years of service may retire and begin to receive the actuarial equivalent of his
or her pension benefits.  The spouse of an employee who would have been eligible
for early  retirement at death,  and married at least one year, is entitled to a
monthly benefit  equivalent to 50% of the amount of the  actuarially  equivalent
joint and survivor  annuity which would have been payable to a participant as of
the participant's normal retirement age.

         Compensation  covered by the Pension Plan for named executive  officers
generally corresponds with the base salary for each such individual,  subject to
the annual maximum.  As of September 30, 1998,  years of  participating  service
under the pension plan were 6.5 years for Mr. Bohn,  8.5 years for Mr.  Goodson,
2.5 years for Mr. Szews, 3.0 years for Mr.
Dempsey, 7.5 years for Mr. Hollowell, and 6.8 years for Mr. Zolnowski.

         The following table shows at different levels of compensation and years
of credited  service the estimated  annual  benefits  payable as a straight life
annuity to Mr. Bohn, assuming retirement at age 65, pursuant to the supplemental
retirement benefit provision  contained in Mr. Bohn's employment  agreement with
the company (the "Supplemental Retirement Benefit"):

         Under the  Supplemental  Retirement  Benefit,  Mr.  Bohn is entitled to
receive upon  retirement a monthly  benefit equal to 30% of Mr.  Bohn's  average
monthly compensation at age 55 increasing to 50% of average monthly compensation
at age 62, reduced by the amount of any pension payable by the company under the
Pension Plan and subject to  adjustment to the extent Mr. Bohn has not completed
18 years of employment  after  December 31, 1997 (the  "Supplemental  Retirement
Benefit  Amount").  Average monthly  compensation is based on the average of Mr.
Bohn's  compensation  for the  three  most  recent  years  prior  to Mr.  Bohn's
retirement or other termination. Mr. Bohn's spouse is entitled to receive 50% of
the Supplemental  Retirement  Benefit Amount that would have been payable to Mr.
Bohn in the event of Mr. Bohn's death.  Compensation covered by the Supplemental
Retirement  Benefit for Mr. Bohn generally  corresponds with the base salary for
Mr. Bohn.  As of September 30, 1998,  Mr. Bohn had .75 years of Benefit  Service
under the Supplemental Retirement Benefit.

Agreements with Named Executive Officers

         Except  as  described  below,  the  company  does not  have  employment
agreements with the named executive officers.

         The  company  entered  into an  employment  agreement  with Mr. Bohn on
October 15, 1998.  Under this  agreement , the company agreed to employ Mr. Bohn
as President  and Chief  Executive  Officer of the company  until  September 30,
2001, with the term of employment  automatically renewed for successive one-year
periods  thereafter unless either party gives notice of non-renewal at least two
years prior to September 30, 2001, or the end of the then current term. Mr. Bohn
receives  an annual  base  salary of not less than  $500,000  and is entitled to
participate in the bonus plan for senior management personnel of the company and
stock-based  compensation  programs in effect for other senior executives of the
company. Mr. Bohn is also entitled to a supplemental retirement benefit intended
to compensate him upon  retirement as more fully  described  above under Pension
Plan Benefit. If Mr. Bohn's employment with the company is terminated during the
term of this  agreement  by the  company  without  cause or by Mr. Bohn for good
reason,  then the company is obligated to continue  paying his salary and fringe
benefits for the remainder of the term as provided in the agreement.

         The company entered into an employment  agreement with Mr. Hollowell on
August 31,  1995,  under which the company  will  employ him as  Executive  Vice
President of the company.  The  agreement  has been  extended and now expires on
September  30, 1999.  Mr.  Hollowell  receives an annual base salary of not less
than $170,000,  and  participates  in the company's  bonus program for executive
officers.  If Mr.  Hollowell's  employment with the company is terminated during
the term of this agreement in connection with a material breach of the agreement
by the company,  then the company is obligated to continue paying his salary and
fringe benefits for the remainder of the term, as provided in the agreement.


                                        9





         The  company  has  agreements  with  Messrs.   Bohn,  Szews,   Dempsey,
Hollowell,  and  Zolnowski  which  provide  that each  executive  is entitled to
benefits  if,  after a change  in  control  (as  defined)  of the  company,  his
employment is ended through (i) termination by the company, other than by reason
of death or  disability or for cause (as defined),  or (ii)  termination  by him
following the first  anniversary  of the change in control or due to a breach of
the  agreement  by  the  company  or  a  significant   adverse   change  in  his
responsibilities.  The benefits provided are: (a) a cash termination  payment of
up to three  times the sum of the  executive's  annual  salary  and his  highest
annual bonus during the three years before the termination and (b)  continuation
of equivalent hospital, medical, dental, accident, disability and life insurance
coverage as in effect at the  termination  for a period which generally will end
two years after such  change in  control.  The  agreement  provides  that if any
portion of the benefits under the agreement or under any other  agreement  would
constitute an "excess  parachute  payment" for purposes of the Internal  Revenue
Code of  1986,  as  amended  (the  "Code"),  benefits  are  reduced  so that the
executive  is entitled to receive $1 less than the maximum  amount  which he can
receive without  becoming  subject to the 20% excise tax imposed by the Code, or
which the company may pay without loss of deduction under the Code.

         The company entered into a separation  agreement with Mr. Goodson,  the
company's former Chairman and Chief Executive Officer, on June 5, 1998. Pursuant
to the terms of this agreement,  Mr.  Goodson's  duties with the company and its
subsidiaries ceased as of October 9, 1997, and he was retained by the company as
a consulting  employee beginning on his resignation date and ending on September
30, 1998 (the  "Transition  Period").  The company agreed to (i) pay Mr. Goodson
salary at the rate of $400,000 per year during the Transition  Period,  (ii) pay
Mr.  Goodson an  additional  salary  payment of  $581,503 on the last day of the
Transition  period,  (iii) accrue  benefits  under the  supplemental  retirement
benefits arrangement contained in Mr. Goodson's employment agreement through the
Transition  Period,  and (iv) vest  options to purchase  9,000  shares of Common
Stock granted under the 1990 Plan on September  28, 1998.  Under this  agreement
Mr. Goodson agreed not to be employed by or affiliated with certain  competitors
of the company during the period  beginning on this  resignation date and ending
September 30, 1999 (the  "Restricted  Period") and,  among other things,  not to
solicit for employment any person  employed by the company during the Restricted
Period.  Mr. Goodson also agreed to a  confidentiality  arrangement and released
the company from any and all liability.

Certain Agreements

         In  connection  with  their  retirement  as  employees  of the  company
effective  February  11,  1994,  the company  entered  into  special  retirement
arrangements with Stephen P. Mosling and J. Peter Mosling,  Jr., who continue to
serve as Directors of the company.  Those arrangements included (i) supplemental
retirement  payments of $70,000 per calendar year from February 11, 1994,  until
age 55 (on February 11, 1998,  Mr. S. P. Mosling was 52, and Mr. J. P.  Mosling,
Jr. was 54); (ii)  supplemental  retirement  payments  after age 55 in an amount
equal to $25,000 per calendar  year;  and (iii)  entitlement,  at the  company's
expense and until age 65, to the standard  medical and life  insurance  coverage
that the company offers to salaried employees.

                     REPORT OF THE HUMAN RESOURCES COMMITTEE

         Responsibility  for  executive  officer  compensation  is vested in the
Board of Directors and its Human Resources  Committee.  This function previously
was  performed by the  Compensation  Committee of the Board of  Directors.  That
committee  was  reconstituted,  with  broadened  responsibilities,  as the Human
Resources Committee in 1998. The Human Resources Committee meets as necessary to
review with the President and Chief  Executive  Officer the performance of other
executive  officers  of  the  company,  and  without  him in  evaluation  of his
performance.   The  Human  Resources  Committee   recommends  executive  officer
compensation  to the Board of  Directors,  which acts upon such  recommendations
after review and discussion.  The Human Resources  Committee is also responsible
for  establishing  and  administering  the  policies  that  govern  the award of
incentives.  In fiscal 1998,  the Board of Directors did not modify or reject in
any material way the Human Resources Committee's recommendations.

         The  practice  of  the  company  with  respect  to  executive   officer
compensation  is to place a significant  part of total  compensation at risk and
related to the financial  performance of the company. At the conclusion of 1996,
the Human  Resources  Committee  took the action of basing the risk component of
executive  officer  compensation for fiscal year 1997 entirely upon the value of
shares of the Common Stock of the company by providing that the after-income tax
amount of bonuses  would be  payable in  restricted  shares of such  stock.  The
restrictions  against  transfer as to such shares will lapse  ratably over three
years  following  the  date of such  awards  which  was  October  31,  1997.  No
restricted shares of stock were awarded in 1998.

                                       10




         The risk component of executive  officer  compensation  for fiscal year
1998 was based upon  earnings  performance  of the  company as it  continued  to
integrate the business of Pierce  Manufacturing  Inc., and the projected initial
integration  of the  McNeilus  Companies,  Inc.,  on the  assumption  that  that
acquisition would occur. For all executive  officers other than Messrs.  Goodson
and Bohn,  a target bonus of 40% of base salary was set at earnings per share of
$1.50,  with a  minimum  bonus of 20% of base  salary at  earnings  per share of
$1.35, and a maximum bonus of 67% of base salary at earnings per share of $1.70.
For Mr. Bohn, the respective  percentages of base salary for target, minimum and
maximum bonus potential at those respective earnings per share amounts were 60%,
30% and  100%.  Mr.  Goodson  was  not  awarded  any  bonus  compensation.  (See
Agreements with Named Executive Officers, above.)

         The company's  executive  officer  compensation  historically  has been
comprised of base salary, annual incentive  compensation and long-term incentive
compensation  in the form of stock  options.  In order to  attract,  retain  and
provide  incentives  to valued  executives,  the Human  Resources  Committee has
established  base  salary  ranges at  competitive  levels and has set  incentive
opportunities  in  conformity to  competitive  practices.  To gauge  competitive
practice,  the Human  Resources  Committee has  considered the experience of the
company in the last four years in recruiting  new senior level  executives,  and
has sought the advice of Towers  Perrin,  an executive  compensation  consulting
firm that advised the Human Resources Committee extensively in 1994, in 1996, in
1997 and, as a result of the  substantial  growth of the company  resulting from
its  acquisitions of Pierce  Manufacturing  Inc. and McNeilus  Companies,  Inc.,
again in 1998.

         For purposes of determining  competitive  levels,  the Human  Resources
Committee focused primarily upon data reflecting compensation paid to executives
with similar responsibilities at industrial companies of a similar revenue size.
The Human  Resources  Committee  believes  that the  company's  competitors  for
executive  talent  include  significantly  more  companies than those peer group
companies for which stock  performance is reflected in the performance graph set
forth  elsewhere  in this  Proxy  Statement.  Further,  the  company  often  has
recruited  executives from automotive  component  manufacturers,  and from other
manufacturers,  some of which are  members  of the  industry  index used for the
performance graph.  Finally, the company has had a number of recent occasions to
evaluate  competitive  compensation  issues in hiring  and  retaining  executive
officers and other highly paid managers.

Base Salary

         The  company  has  established  base  salary  ranges  that are based on
competitive  data and has granted salary  increases  based upon a combination of
the  performance  of the executive  officer,  his or her salary level within the
applicable  competitive  range,  the performance of that part of the business of
the  company  for  which the  executive  officer  is  responsible,  and  company
performance   and   profitability.   In  considering   such  executive   officer
performance,  the Human Resources  Committee takes into  consideration  the fact
that the company has commercial lines of business in which financial success and
market share are most directly affected by price and service competition,  which
contrast  with  the  defense  business  which  is  more  directly   affected  by
performance  requirements of a major customer.  The performance of the President
and Chief  Executive  Officer is  evaluated on the basis of  achievement  of his
goals and  objectives,  which are  established  annually by the Human  Resources
Committee and which include the  profitability and performance of the company as
a whole.  Mr.  Goodson's  base salary was  continued at the level set for fiscal
years 1996 and 1997  through  October 9, 1998.  Payments to him after that date,
pursuant to the  separation  agreement  dated October 9, 1998,  confirmed  prior
contractual  commitments  to him.  On these  bases,  which  included  successful
integration of the businesses of Pierce  Manufacturing  Inc. and, when acquired,
McNeilus  Companies,  Inc.,  Mr.  Bohn's  base salary for fiscal 1998 was set at
$385,000,  and his maximum bonus potential was increased to 100% of base salary.
On the same bases,  Mr.  Bohn's base salary for 1999 was  increased to $500,000,
and his maximum bonus compensation potential was increased to 120% of salary.

Annual Incentive Awards

         The company  maintains an Incentive  Compensation  Plan ("ICP") that is
designed to reward  achievement of business  objectives  determined by the Human
Resources  Committee  and  approved  by  the  Board  of  Directors.  Awards  are
considered for those executives who the Human Resources Committee determines can
have a significant  impact upon company  performance.  To ensure compliance with
this objective,  the Human Resources Committee consulted extensively with Towers
Perrin,  as  indicated,  to verify that the annual  incentive  practices  of the
company  do indeed  provide  appropriately  competitive  incentive  compensation
opportunities.

                                       11



         At the  beginning  of each  year,  the  President  and Chief  Executive
Officer in consultation with the Human Resources  Committee  establishes company
and individual  executive officer  performance  objectives.  The Human Resources
Committee authorizes a two-component fund for incentive compensation. The first,
which was $150,000 in 1998, was used by Mr. Bohn to recognize  unanticipated but
significant  individual  contributions by company employees during the year. The
Human Resources  Committee was timely advised by Mr. Bohn of the reasons for and
amounts of all awards. No awards were made from this pool during the year to any
executive officers. As President and Chief Executive Officer, Mr.
Bohn also will exercise this authority in 1999.

         The second  component  of the fund is a  percentage  of base salary for
executive  officers  and  other  highly  compensated  employees.  For  executive
officers,  this percentage ranges in 1999 from 40% of base salary to a high, for
Mr. Bohn, of 120%. This component is intended to compensate  executive  officers
to the full extent of potential  annual  incentive  compensation as and when the
company  realizes  the full  extent of its  intended  operating  results.  Bonus
payments  for 1998  commenced  under this  component  of the ICP if the  company
achieved 100% of its targeted profits.  At earnings of $1.79 per share for 1998,
the bonus payment  resulted in an aggregate  award of 67% of the bonus potential
to the named executive officers other than Messrs. Goodson and Bohn, and of 100%
of the bonus potential for Mr. Bohn. The over-all  operations of the company did
achieve targeted objectives. As a result, the company has paid executive officer
bonuses from this component of the fund for 1998.

Long-Term Incentive Compensation

         In 1990, the  shareholders  approved the creation of an Incentive Stock
Plan. Its objectives are to encourage and facilitate  ownership of company stock
by  those  highly  compensated  employees  for  whom a  personal  commitment  to
long-term  shareholder  interests is most  important.  The practice of the Human
Resources  Committee  has been to grant  stock  options  based upon the level of
responsibility placed on each executive officer, the individual performance, and
upon the potential of the  executive to contribute to the future  success of the
company.  As a result,  stock options for shares of Common Stock were awarded to
Mr. Bohn for 1998, as follows:  on November 19, 1997, 25,000 shares; on February
2, 1998,  25,000  shares;  and on September 21, 1998,  32,500 shares  subject to
action of the Class A Common  Stock  shareholders  to amend the 1990 Plan at the
1999 Annual Meeting of Shareholders.

Code Section 162(m)

         Section 162(m) of the Internal Revenue Code limits the company's income
tax deduction  for  compensation  paid in any taxable year to certain  executive
officers to $1,000,000,  subject to several exceptions.  It is the policy of the
Human Resources  Committee that the company should use its best efforts to cause
any  compensation  paid to  executives in excess of such dollar limit to qualify
for such exceptions and, therefore, to continue to be deductible by the company.
In particular, the 1990 Plan is designed to permit awards which will continue to
qualify for the Code's exception for "performance-based compensation."

Conclusion

         The Human  Resources  Committee  believes that these  components of the
executive  compensation program provide compensation for executive officers that
is competitive with that offered by corporations with which the company competes
for retention of executive excellence. Further, and particularly with the recent
changes to the incentive compensation  component,  the Human Resources Committee
believes executive  management equity incentive is better aligned with interests
of the shareholders and these incentives will motivate executives for the longer
term challenges with which the company is faced.

Human Resources Committee Interlocks and Insider Participation

         During  fiscal year 1998,  Mr.  Stephen P.  Mosling was a member of the
Human Resources Committee.  During fiscal year 1998, and ending on September 30,
1998,  the company  incurred  rental  expense of $128,400 per year under a lease
between the company and Cadence  Company,  a partnership  of which Mr.  Mosling,
together with his four sisters and his brother J. Peter Mosling,  Jr., are equal
partners.  The lease related to property and a building used by the company as a
new product  development  center. The lease would have expired on July 31, 1999.
On  September  30,  1998,  the  company  acquired  the  property  for the sum of
$772,500,  which  reflected  the  average of two M.A.I.  appraisals  of the fair
market value of property commissioned by the company.

Performance Information

         Set forth below is a line graph comparing the yearly  percentage change
during the last five years in the company's  cumulative total shareholder return
on the Common Stock with the  cumulative  total  return of the  companies on the
NASDAQ Market Index,  the companies  currently in the "Media  General  Financial
Services"  Standard Industry  Classification  Code 371 Index (motor vehicles and
equipment) (the "SIC Code 371 Index") and the companies in a peer group selected
in  good  faith  by  the  company  consisting  of  PACCAR,   Inc.  and  Navistar
International  Corp.  The company has used the peer group in this graph in prior
years, but has selected the SIC Code 371 Index to replace the peer group because
the  company  believes  the SIC Code 371 Index is more broad  based ad  includes
companies whose businesses are more like those of the company than the companies
currently  reflected  in the peer group.  The  comparison  assumes that $100 was
invested on September 30, 1993, in the company's Common Stock, the NASDAQ Market
Index,  the SIC  Code  371  Index  and the  peer  group.  Total  return  assumes
reinvestment of dividends.

Compensation of  Directors

         Each  outside  Director of the  company  (currently  Messrs.  Andersen,
Carroll,  Grebe,  J.P.  Mosling,  Jr., S. Mosling and Sim,  Ms.  Hempel and Gen.
Franks) is  entitled  to receive an annual  retainer of $16,000 for service as a
Director,  plus $1,000 for each Board  meeting  attended,  and a fee of $750 for
each meeting attended of the audit, human resources,  executive,  and governance

the proposed  amendment to the 1990 Plan,  each outside  Director  annually will
receive  options to acquire 2,000 shares of Common Stock  immediately  following
his or her  election  at the  Annual  Meeting.  The price of shares  under  such
options is the closing price of such shares on the date of award.

                        PROPOSAL FOR SECOND AMENDMENT TO
                          THE OSHKOSH TRUCK CORPORATION
                            1990 INCENTIVE STOCK PLAN

Summary of Proposal

         General.  In 1991,  shareholders  of the company  approved  the Oshkosh
Truck Corporation 1990 Incentive Stock Plan (the "1990 Plan"). The original plan
authorized  the  issuance  of up to  400,000  shares of Common  Stock.  In 1995,
shareholders  amended the 1990 Plan to increase the aggregate  authorized  share
issuance to 825,000.  Since the  inception  of the 1990 Plan,  49,703  shares of
restricted Common Stock have been issued and vested under the 1990 Plan, 208,129
shares of Common Stock have been issued  pursuant to options  granted  under the
1990 Plan,  and options to purchase an additional  711,701 shares under the 1990
Plan remain outstanding. The Board of Directors wishes to continue the 1990 Plan
and  accordingly  is seeking the  approval of holders of Class A Common Stock to
amend the 1990 Plan to authorize the issuance of an additional 425,000 shares of
Common  Stock  under the plan and to effect  certain  other  changes to the plan
described below, including increasing the size of the annual grant of options to
nonemployee directors.  If the amended 1990 Plan is approved, then the aggregate
number of shares  authorized to be issued under the 1990 Plan will be 1,250,000.
The Restated  Articles of Incorporation of the company authorize the issuance of
1,000,000 shares of Class A Common Stock and 18,000,000  shares of Common Stock.
There were 296,756 shares of Class A Common Stock and 8,124,745 shares of Common
Stock issued and  outstanding  as of December 16, 1998,  and the market value of
one share of Common Stock as of that date was $30.75. The following is a summary
discussion  of the amended 1990 Plan.  Copies of the complete  amended 1990 Plan
are available without charge upon written request mailed to the Secretary of the
company at the company's address set forth on the face of this Proxy Statement.

         Participation.  The amended  1990 Plan,  which is  administered  by the
Human  Resources  Committee,  provides for the granting to key  employees of the
company  and  its  subsidiaries  of  stock  options  and/or   restricted  stock.
Currently,  approximately  19 employees are eligible to  participate in the 1990
Plan. The number of participants  could increase based upon future growth by the
company.  The selection of  participants  will be based upon the Human Resources
Committee's  opinion  that  the  participant  is  in a  position  to  contribute
materially  to  the  company's  continued  growth  and  development  and  to its
long-term financial success.  Under the 1990 Plan,  nonemployee directors of the
company also receive  grants of stock options.  The company  currently has eight
nonemployee directors.

         Stock Subject to the 1990 Plan.  The amended 1990 Plan provides for the
sale or grant of up to 1,250,000  shares (either  authorized but unissued shares
or treasury  shares) of Common Stock,  subject to adjustment as described below.
If an option  granted  under the 1990 Plan  expires,  is canceled or  terminated
unexercised as to any shares, or if the company acquires any shares subject to a
restricted  stock grant,  then such shares will again be available  for issuance
under the 1990 Plan.  The amended 1990 Plan also  provides that the total number
of shares of Common Stock subject to issuance  pursuant to options granted under
the 1990 Plan in any five year period to any one person may not exceed  150,000,
subject to adjustment as described below.


                                       14



         In the event of any change in the outstanding Common Stock by reason of
a stock  dividend or split,  recapitalization,  merger,  combination,  spin-off,
exchange  of shares  or other  similar  corporate  change,  the Human  Resources
Committee will adjust the number of shares subject to outstanding options, their
stated  option  prices,  the  number of shares  subject to the 1990 Plan and the
number of shares that may be issued to any one person.  In such event, the Human
Resources  Committee may also adjust the number of shares  subject to restricted
stock grants.

         Options.  The amended 1990 Plan provides  that,  upon the conclusion of
the 1999 Annual Meeting and each subsequent  annual meeting of the  shareholders
of the  company,  each  nonemployee  director  at such  time  will be  granted a
nonqualified option to purchase 2,000 shares of stock,  compared to 1,000 shares
prior to the amendment.  The exercise price per share of Common Stock subject to
an option  granted to a nonemployee  director under the amended 1990 Plan is the
fair market  value of the Common  Stock on the date the option is  granted.  The
options  vest  ratably  over the three  year  period  from the date of grant and
expire ten years after the date of grant.  The option  exercise price is payable
to  the  company  in  cash,  by  tendering  shares  of  Common  Stock  or by any
combination thereof.

         Options  other than  those  granted to  nonemployee  directors  will be
granted  to  participants  at such time as the Human  Resources  Committee  will
determine.  The Human  Resources  Committee  will also  determine  the number of
options  granted and  whether an option is to be an  incentive  stock  option or
nonqualified stock option. The aggregated fair market value of Common Stock with
respect to which incentive stock options are exercisable for the first time by a
participant during any calendar year shall not exceed $100,000. The option price
per share of Common Stock will be fixed by the Human  Resources  Committee,  but
will not be less than the fair market  value of the Common  Stock on the date of
grant. The Human Resources  Committee will determine the expiration date of each
option but, in the case of an incentive  stock option,  the expiration date will
not be later  than the tenth  anniversary  of the grant  date.  Options  will be
exercisable at such times and be subject to such  restrictions and conditions as
the Human Resources Committee deems necessary or advisable,  except that options
granted  to  officers,  directors  or  more  than  10%  shareholders  may not be
exercised  until at least six months after the date of grant.  No option will be
assignable  or  transferable  by a  participant,  except  by will or the laws of
descent and  distributor,  and options may be  exercised  during the life of the
participant only by the participant. At the time of exercise, the option must be
paid in full either (i) in cash or its equivalent,  (ii) by tendering  shares of
previously  acquired  stock  having a fair market  value at the time of exercise
equal to the option price, or (iii) by a combination of (i) and (ii).

         Restricted  Stock.  The Human  Resources  Committee may grant shares of
restricted stock to such participants,  in such amounts,  at such times and with
such  restriction  on transfer  as it will  determine,  except that  nonemployee
directors of the company are not entitled to received  restricted  stock grants.
Shares of restricted stock may not be transferred in any way, other than by will
or by the laws of descent and distribution, for the period of time determined by
the Human  Resources  Committee  or prior to the earlier  satisfaction  of other
conditions  specified  by the  Human  Resources  Committee  as set  forth in the
written stock grant.  Any  restricted  stock granted to an officer,  director or
more than 10% shareholder may not be sold for at least six months after the date
it is granted.  After the period of restriction,  the shares of restricted stock
become freely transferable. During the period of restriction,  participants will
have sole voting rights, and will be entitled to receive all dividends and other
distributions with respect to restricted shares.

         Change of Control.  The Human Resources  Committee,  either at the time
options  or  shares  of   restricted   stock  are  granted  or,  under   certain
circumstances,  at any time  thereafter,  may provide for the acceleration of or
accelerate the  exercisability of options and/or the last day of the restriction
period for restricted stock upon a change of control of the company.

         Certain Federal Income Tax Consequences. In general, a participant will
not  recognize  income for federal  income tax  purposes at the time of grant or
exercise of an incentive stock option. However, upon exercise, the excess of the
fair market value of the stock over the option price is treated as an adjustment
for purposes of the alternative  minimum tax. If a participant  holds the shares
received on exercise of an  incentive  stock  option for at least two years from
the  date of  grant  and one year  from  the  date of  exercise,  he or she will
recognize no federal taxable income as a result of exercise.  Any gain (or loss)
realized on the  disposition  of the stock will be treated a  long-term  capital
gain (or loss), and no deduction will be allowed to the company.  If the holding
period  requirements  are not  satisfied,  then the  participant  will recognize
ordinary  income at the time of the  disposition  equal to the lesser of (i) the
gain realized on the disposition or (ii) the difference between the option price
and the fair market value of the share on the date of exercise.  Any  additional
gain will be a long-term or short-term  capital gain,  depending upon the length
of time the shares were held.  The company is entitled to a tax deduction  equal
to the amount of ordinary income recognized by the participant.

                                       15




         The grant of a nonqualified stock option will not result in any taxable
income to a participant  or director  recipient.  A participant or director will
recognize  ordinary income upon exercise of a nonqualified  stock option. In any
case, the amount of ordinary  income  recognized  will be equal to the excess of
the fair market value of the stock at the time the income is recognized over the
option  price.  The company is entitled to a tax deduction in the same amount at
the time the participant or director recipient recognizes ordinary income.

         Awards to Certain Persons.  During 1998, the Human Resources  Committee
approved  grants of stock  options to executive  officers and others that do not
require  shareholder  approval of the amended 1990 Plan (see  "Option  Grants in
1998 Fiscal Year"). However, the option grants to executive officers approved by
the Human  Resources  Committee  on September  21,  1998,  will not be effective
unless  holders of Class A Common Stock approve the amended 1990 Plan. Set forth
in the table below is  information  regarding  awards of stock options under the
amended 1990 Plan to the persons noted that require shareholder  approval of the
amended 1990 Plan:

         Except for stock options granted to nonemployee  directors on an annual
basis under the amended 1990 Plan,  the company cannot  currently  determine the
awards  that may be granted in the future to the  persons  named above under the
amended  1990 Plan.  Such  determinations  will be made from time to time by the
Human Resources Committee.

         Duration  of Plan.  The amended  1990 Plan will remain in effect  until
after  Common  Stock  subject  to it has  been  purchased  or  acquired,  unless
terminated by the Board of Directors. However, no option or restricted stock may
be granted after  September 21, 2008 (which  represents an extension  from March
29, 2004).

         Amendment,  Modification  and  Termination.  The Board of Directors may
amend,  modify  or  terminate  the 1990 Plan at any time,  except  that,  unless
approved by the shareholders,  no amendment will (i) change the provision so the
1990 Plan  regarding  option  price or  increase  the  maximum  number of shares
issuable under the 1990 Plan generally or to any one person (except  pursuant to
a change in the  number of  outstanding  shares  of  Common  Stock as  described
above); (ii) materially modify the eligibility requirements for participation in
the 1990  Plan;  (iii)  materially  increase  the  cost of the 1990  Plan to the
company or materially increase the benefits to participants under the 1990 Plan;
(iv) extend the period during which options or restricted  stock may be granted;
or (v) extend the maximum period after the date of grant during which

                                       16



options may be exercised.  Termination,  amendment or  modification  of the 1990
Plan will not  adversely  affect the  rights of  participants  under  options or
restricted stock previously granted without the consent of the participants.

         Vote  Required.  The  affirmative  vote of a majority  of the shares of
Class A Common Stock  represented  and voted at the Annual  Meeting  (assuming a
quorum is present) is required to approve the 1990 Plan. Any shares not voted at
the Annual Meeting (whether by broker nonvotes or otherwise, except abstentions)
will have no impact on the vote.  Shares as to which holders abstain from voting
will be treated as votes against the proposal.

         Recommendation.  The  Board  recommends  a  vote  FOR  approval  of the
amendments  to the Oshkosh  Truck  Corporation  1990  Incentive  Stock Plan,  as
amended.

                        SELECTION OF INDEPENDENT AUDITORS

         Ernst & Young LLP has  served  as the  company's  independent  auditors
since 1976,  including  during  fiscal 1998.  The  independent  auditors for the
company for fiscal 1999 will be approved formally in May 1999.

         Representatives  of Ernst & Young  LLP will be  present  at the  Annual
Meeting and will have an opportunity to make a statement if they desire to do so
and to respond to appropriate questions.

                        BOARD OF DIRECTORS AND COMMITTEES

         The Board of Directors  held seven  meetings  during fiscal 1998.  Each
incumbent  Director  during the last year attended at least 75% of the aggregate
of the total  meetings  of the Board of  Directors  held while such person was a
Director  and the  total  meetings  of the  Committees  of the Board on which he
served.  The  company has  appointed  Executive,  Human  Resources,  Audit,  and
Governance Committees for Class A Common Stock and Common Stock Directors of the
Board of Directors.

         The  functions  of the  Executive  Committee  are to oversee  corporate
policy,  to review  management  proposals and to make  recommendations  on those
proposals  to the Board of Directors  and to exercise  certain  other  executive
powers. The committee,  which held eight meetings during fiscal 1998,  currently
consists of Messrs. Bohn, Carroll, J.P. Mosling, Jr. and S.P. Mosling.

         The Human  Resources  Committee  recommends  all officer  salaries  and
supplemental compensation plans to the Board of Directors. The committee,  which
held five  meetings  during  fiscal 1998,  currently  consists of Ms. Hempel and
Messrs. Andersen, Carroll and S.P. Mosling and Gen. Franks.

         The functions of the Audit  Committee are to meet with Arthur  Anderson
LLP,  acting under  contract as internal  auditors of the company,  and with the
independent  auditors of the company  regarding the financial  statements of the
company, the adequacy of internal controls and procedures of the company as they
relate to such  statements,  and adherence of employees to company  policies and
procedures which affect such  statements.  The committee  currently  consists of
Messrs.  Andersen,  Carroll, Grebe, Sim and J.P. Mosling, Jr. The committee held
three meetings during fiscal 1998,  including two meetings in executive  session
with representatives of Ernst & Young LLP.

         The  Governance  Committee  recommends  individuals  for nomination and
appointment or election to the Board of Directors of the company.  The committee
currently consists of Messrs. Carroll, Grebe and Gen. Franks. It met three times
during fiscal year 1998.

                                  OTHER MATTERS

         At the Annual  Meeting,  shareholders  will approve the minutes for the
1998 Annual Meeting;  such action will not constitute approval or disapproval of
any of the matters referred to in the minutes.

         Management knows of no matters other than those stated which are likely
to be brought before the Annual  Meeting.  However,  in the event that any other
matter  shall  properly  come before the  meeting,  it is the  intention  of the
persons named in the forms of proxy to vote the shares  represented by each such
proxy in accordance with their judgment on such matters.

         All shareholder  proposals  pursuant to Rule 14a-8 under the Securities
Exchange Act of 1934, as amended ("Rule  14a-8"),  for  presentation at the 2000
Annual  Meeting must be received at the offices of the  company,  P.O. Box 2566,
Oshkosh,  Wisconsin  54903,  by August 17, 1999,  for inclusion in the company's
2000 proxy  statement.  If the company does not receive  notice of a shareholder
proposal  submitted  otherwise  than pursuant to Rule 14a-8 prior to November 8,
1999,  then the notice will be  considered  untimely  and the  persons  named in
proxies  solicited  by the Board of  Directors  for the 2000 Annual  Meeting may
exercise discretionary voting power with respect to such proposal.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section  16(a) of the  Securities  Exchange  Act of 1934  requires  the
company's  officers and directors to file reports of stock ownership and changes
in stock ownership with the Securities and Exchange Commission.  SEC regulations
require officers and directors to furnish the company with copies of all Section
16(a) forms they file.  Based solely on a review of such forms  furnished to the
company,  the company  believes that during the period from  September 30, 1997,
through September 30, 1998, all of its officers and directors, other than as set
forth below,  complied  with  Section  16(a) filing  requirements.  Gen.  Franks
inadvertently  did not timely file one Form 4 covering one  transaction  for his
purchase of 200 shares of Common Stock. Ms. Hempel  inadvertently did not timely
file a Form 3 upon her election as a Director of the company.

COST OF SOLICITATION

         The  cost of  soliciting  proxies  will be borne  by the  company.  The
company  expects to  solicit  proxies  primarily  by mail.  Proxies  may also be
solicited  personally and by telephone by certain officers and regular employees
of the company.  It is not anticipated that anyone will be specially  engaged to
solicit proxies or that special  compensation will be paid for that purpose. The
company will reimburse brokers and other nominees for their reasonable  expenses
in communicating with the persons for whom they hold stock of the company.

                                    By order of the Board of Directors,



                                    TIMOTHY M. DEMPSEY, Secretary
                                    OSHKOSH TRUCK CORPORATION

                      1990 INCENTIVE STOCK PLAN, as amended


Section 1.        Establishment, Purpose, and Effective

hereby  establishes  the  "1990  INCENTIVE  STOCK  PLAN"  (the  "Plan")  for key
employees  and for  directors of the  Corporation  who are not  employees of the
Corporation or any  Subsidiary.  The Plan permits the grant of Stock Options and
Restricted Stock.

          1.2  Purpose.  The purpose of the Plan is to advance the  interests of
the Corporation  and its  Subsidiaries  and promote  continuity of management by
encouraging  and  providing  for the  acquisition  of an equity  interest in the
success of the  Corporation by key employees and by enabling the  Corporation to
attract and retain the services of key employees upon whose judgment,  interest,
skills,  and special effort the successful  conduct of its operations is largely
dependent.  In addition,  the Plan is designed to promote the best  interests of
the Corporation and its  shareholders by providing a means to attract and retain
competent  directors who are not employees of the  Corporation or any Subsidiary
and to provide  opportunities  for stock  ownership by such directors which will
increase their proprietary interest in the Corporation and, consequently,  their
identification with the interests of the shareholders of the Corporation.

          1.3 Effective  Date. The Plan was initially  effective  April 9, 1990,
was  amended  effective  April  25,  1994,  and was  further  amended  effective
September 21, 1998, subject to subsequent approval by the holders of outstanding
shares of common stock of the  Corporation  entitled to vote thereon at the next
annual meeting of the Corporation's shareholders.

Section 4.        Stock Subject to Plan

          4.1 Number.  The total  number of shares of Stock  subject to issuance
under  the  Plan  may  not  exceed  one  million  two  hundred  fifty   thousand
(1,250,000). The total number of shares of Stock subject to issuance pursuant to
Options granted under the Plan in any five year period to any one person may not

adjustment upon occurrence of any of the events indicated in Subsection 4.3. The
shares to be  delivered  under  the Plan may  consist,  in whole or in part,  of
authorized  but  unissued  Stock or treasury  Stock,  not reserved for any other
purpose.

          4.2 Unused Stock; Unexercised Rights. In the event any shares of stock
are  subject  to an Option  which,  for any  reason,  expires  or is  terminated
unexercised as to such shares,  or any shares of Stock,  subject to a Restricted

consolidation,  combination,  exchange  of  shares  or other  similar  corporate
change,  the  aggregate  number  of  shares  of  Stock  (or the  stock  or other
securities  that had been issued in exchange for the shares of Stock) subject to
each  outstanding  Option,  and its stated Option price,  shall be appropriately
adjusted by the Committee,  whose determination  shall be conclusive;  provided,
however,  that fractional shares shall be rounded to the nearest whole share. In
such  event,  the  Committee  shall  also have  discretion  to make  appropriate
adjustments in the number and type of shares subject to Restricted  Stock grants
then  outstanding  under  the  Plan  pursuant  to the  terms of such  grants  or
otherwise. In the event of any other change in the Stock, the Committee shall in
its sole discretion determine whether such change equitably requires a change in
the  number  or type of  shares  subject  to any  outstanding  Stock  Option  or
Restricted  Stock grant and any such  adjustment  made by the Committee shall be
conclusive.   Notwithstanding  the  foregoing,   Options  subject  to  grant  or
previously  granted to Non-Employee  Directors under the Plan at the time of any
event described in this Section 4.3 shall be subject to only such adjustments as
shall be  necessary  to  maintain  the  relative  proportionate  interest of the
Non-Employee  Directors  and  preserve,  without  exceeding,  the  value of such
Options.

Section 5.        Duration of Plan

          5.1 Duration of Plan. The Plan shall remain in effect,  subject to the
Board's right to earlier  terminate the Plan pursuant to Subsection 10.3 hereof,
until all Stock subject to it shall have been purchased or acquired  pursuant to
the provisions hereof.  Notwithstanding  the foregoing,  no Option or Restricted
Stock may be granted under the Plan on or after September 21, 2008.

Section 6.        Stock Options

          6.1 Grant of Options.  Subject to the  provisions of Sections 4 and 5,
Options  may be  granted  to  Participants  at any time and from time to time as
shall be  determined  by the  Committee.  Non-Employee  Directors  shall  not be
eligible to be granted Options under the Plan, except as provided in Section 6A.
The  Committee  shall have  complete  discretion  in  determining  the number of
Options granted to each Participant.  The Committee also shall determine whether
an Option is to be an incentive  stock option  within the meaning of Section 422
of the Code or a nonstatutory stock option.  However, in no event shall the Fair
Market  Value  (determined  at the date of grant) of Stock with respect to which
incentive  stock  options are  exercisable  for the first time by a  Participant
during any calendar year exceed one hundred  thousand  dollars  ($100,000).  Nor
shall any incentive stock option be granted to any person who owns,  directly or
indirectly,  stock  possessing more than ten percent (10%) of the total combined
voting  power  of  all  classes  of  stock  of  the  Corporation  ("Ten  Percent
Stockholder").  Nothing in this Section 6 of the Plan 

                                      -4-



shall be deemed to prevent the grant of nonstatutory  stock options in excess of
the maximum established by Section 422 of the Code.

          6.2 Option  Agreement.  Each Option  shall be  evidenced  by an Option
agreement that shall specify the type of Option granted,  the Option price,  the
duration  of the  Option,  the  number of  shares  of Stock to which the  Option
pertains and such other provisions as the Committee shall determine.

          6.3 Option Price. No Option granted pursuant to the Plan shall have an
Option  price that is less than the Fair  Market  Value of the Stock on the date
the Option is granted.

          6.4 Duration of Options.  Each Option shall expire at such time as the
Committee shall determine at the time it is granted; provided,  however, that no
Option that is an incentive  stock option  shall be  exercisable  later than the
tenth (10th) anniversary date of its grant, and no Option that is a nonstatutory
stock  option  shall be  exercisable  more than ten (10) years and one (l) month
after the date of its grant.

          6.5  Exercise  of  Options.  Options  granted  under the Plan shall be
exercisable at such times and be subject to such  restrictions and conditions as
the Committee shall in each instance approve, which need not be the same for all
Participants;  except that Options granted to officers, directors or Ten Percent
Stockholders  may not be exercised  until at least six (6) months after the date
of grant.

          6.6  Payment.  The Option  price upon  exercise of any Option shall be
payable to the Corporation in full either (i) in cash or its equivalent, or (ii)
by tendering  shares of previously  acquired Stock having a Fair Market Value at
the time of exercise equal to the total Option price,  or (iii) by a combination
of (i) and (ii).  The proceeds from such a payment shall be added to the general
funds of the Corporation and shall be used for general corporate purposes.

          6.7  Restrictions on Stock  Transferability.  The Committee may impose
such restrictions on any shares of Stock acquired pursuant to the exercise of an
Option under the Plan as it may deem advisable,  including,  without limitation,
restrictions  under applicable Federal securities law, under the requirements of
any stock exchange upon which such shares of Stock are then listed and under any
blue sky or state securities laws applicable to such shares.

          6.8 Termination of Employment Due to Death,  Disability or Retirement.
In the event the  employment of a Participant  is terminated by reason of death,
Disability or Retirement, the Committee may provide in the Option agreement that
any outstanding  Options shall become immediately  exercisable at any time prior
to the  expiration  date of the Options or within  twelve (12) months after such
date of termination of employment,  whichever period is the shorter. However, in
the case of incentive  stock  options,  the favorable  tax treatment  prescribed
under  

                                      -5-



Section 422 of the Code shall not be available if such options are not exercised
within three (3) months after such date of termination due to Retirement.

          6.9  Termination  of  Employment  Other than for Death,  Disability or
Retirement.  If the employment of the Participant shall terminate for any reason
other  than  death,  Disability  or  Retirement,   the  rights  under  any  then
outstanding  Option  granted  pursuant  to the  Plan  shall  terminate  upon the
expiration date of the Option or three (3) months after such date of termination
of employment,  whichever first occurs,  subject to such exceptions (which shall
be set  forth  in the  Option  Agreement)  as the  Committee  may,  in its  sole
discretion, approve.

          6.10  Nontransferability  of Options. No Option granted under the Plan
may  be  sold,  transferred,   pledged,   assigned  or  otherwise  alienated  or
hypothecated, otherwise than by will or by the laws of descent and distribution.
Further,  all  Options  granted  to  a  Participant  under  the  Plan  shall  be
exercisable during his or her lifetime only by such Participant.

Section 6A.  Non-Employee Director Stock Options

          6A.1 Grant of Options.  Subject to approval of  amendments to the Plan
by the  shareholders of the Corporation as contemplated by Section 1.3, upon the
conclusion of the 1999 annual meeting of the  shareholders  of the  Corporation,
and thereafter,  upon the conclusion of each annual meeting of the  shareholders
of the Corporation,  each Non-Employee  Director at such time shall be granted a
nonqualified Option to purchase 2,000 shares of Stock.

          6A.2 Terms of Options. The right to exercise Options granted to a Non-
Employee Director pursuant to this Section 6A shall accrue as to one-third (1/3)
of the shares on each of the first three  anniversaries of the date of grant. No
partial  exercise of the  Options  may be for less than one hundred  (100) share
lots or multiples thereof.  The term of Options granted pursuant to this Section
6A shall expire ten years and one month from the date of grant or twelve  months
after the  Non-Employee  Director  ceases  for any  reason to be a member of the
Board,  whichever  occurs  first.  The Option  exercise  price shall be the Fair
Market  Value of the Stock on the date each  Option is  granted,  which shall be
payable  to the  Corporation  in full upon  exercise  either  (i) in cash or its
equivalent,  or (ii) by tendering  shares of previously  acquired Stock having a
Fair Market Value at the time of exercise  equal to the total Option  price,  or
(iii) by a combination of (i) and (ii).

                                      -6-



Section 7.  Restricted Stock

          7.1 Grant of Restricted Stock. Subject to the provisions of Sections 4
and 5, the  Committee,  at any time and from time to time,  may grant  shares of
Restricted  Stock under the Plan to such  Participants and in such amounts as it
shall  determine.  Non-Employee  Directors are not eligible to receive grants of
Restricted  Stock  under the Plan.  Each grant of  Restricted  Stock shall be in
writing.

          7.2  Transferability.  Except as  provided  in  Section 7 hereof,  the
shares of  Restricted  Stock  granted  hereunder  may not be sold,  transferred,
pledged, assigned or otherwise alienated or hypothecated for such period of time
as shall be determined by the Committee and shall be specified in the Restricted
Stock grant, or upon earlier  satisfaction  of other  conditions as specified by
the  Committee  in its sole  discretion  and set forth in the  Restricted  Stock
grant;  provided that  Restricted  Stock  granted to officers,  directors or Ten
Percent  Stockholders may not be sold for at least six (6) months after the date
of grant.

          7.3  Other   Restrictions.   The   Committee  may  impose  such  other
restrictions on any shares of Restricted  Stock granted  pursuant to the Plan as
it  may  deem  advisable  including,  without  limitation,   restrictions  under
applicable  Federal or state  securities  laws, and may legend the  certificates
representing Restricted Stock to give appropriate notice of such restrictions.

          7.4  Certificate   Legend.  In  addition  to  any  legends  placed  on
certificates  pursuant to Subsection 7.3 hereof,  each certificate  representing
shares of Restricted Stock granted pursuant to the Plan shall bear the following
legend:

              "The sale or other transfer of the shares of stock
              represented   by   this    certificate,    whether
              voluntary,  involuntary or by operation of law, is
              subject to certain  restrictions  on transfer  set
              forth  in   Oshkosh   Truck   Corporation's   1990
              Incentive  Stock  Plan,  rules  of  administration
              adopted  pursuant  to such  Plan and a  Restricted
              Stock grant dated __________.  A copy of the Plan,
              such rules and such Restricted  Stock grant may be
              obtained  from  the  Secretary  of  Oshkosh  Truck
              Corporation."

          7.5 Removal of Restrictions. Except as otherwise provided in Section 7
hereof,  shares of Restricted  Stock covered by each Restricted Stock grant made
under the Plan shall become freely  transferable  by the  Participant  after the
last day of the Period of  Restriction.  Once the shares are  released  from the
restrictions,  the Participant  shall be entitled to have the legend required by
Subsection 7.4 removed from the Participant's Stock certificate.

                                      -7-



          7.6 Voting  Rights.  During the  Period of  Restriction,  Participants
holding  shares of Restricted  Stock granted  hereunder may exercise full voting
rights with respect to those shares.

          7.7   Dividends  and  Other   Distributions.   During  the  Period  of
Restriction,  Participants  holding shares of Restricted Stock granted hereunder
shall be entitled to receive all  dividends  and other  distributions  paid with
respect  to  those  shares  while  they are so held.  If any such  dividends  or
distributions  are paid in shares of Stock,  the shares  shall be subject to the
same  restrictions  on  transferability  as the shares of Restricted  Stock with
respect to which they were paid.

          7.8  Termination of Employment  Due to  Retirement.  The Committee may
provide in its Restricted Stock grant that in the event a Participant terminates
his or her employment with the Corporation because of Retirement,  any remaining
Period of Restriction  applicable to the Restricted Stock pursuant to Subsection
7.2 hereof shall  automatically  terminate and, except as otherwise  provided in
Subsection  7.3,  the  shares  of  Restricted  Stock  shall  thereby  be free of
restrictions  and freely  transferable.  In the event the Restricted Stock grant
does not automatically  terminate such restrictions and a Participant terminates
his or her employment with the Corporation because of Retirement,  the Committee
may, in its sole  discretion,  waive the  restrictions  remaining  on any or all
shares of Restricted Stock pursuant to Subsection 7.2 hereof and/or add such new
restrictions to those shares of Restricted Stock as it deems appropriate.


          7.9  Termination  of  Employment  Due  to  Death  or  Disability.  The
Committee  may  provide  in its  Restricted  Stock  grant  that  in the  event a
Participant  terminates his or her employment  with the  Corporation  because of
death  or  Disability  during  the  Period  of  Restriction,   the  restrictions
applicable to the shares of Restricted  Stock  pursuant to Subsection 7.2 hereof
shall terminate  automatically  with respect to all of the shares or that number
of shares  (rounded to the nearest  whole  number)  equal to the total number of
shares of Restricted Stock granted to such Participant  multiplied by the number
of full months which have elapsed since the date of grant divided by the maximum
number of full months of the Period of Restriction.  All remaining  shares shall
be  forfeited  and  returned to the  Corporation;  provided,  however,  that the
Committee may, in its sole discretion,  waive the restrictions  remaining on any
or  all  such  remaining  shares  either  before  or  after  the  death  of  the
Participant.

          7.10 Termination of Employment for Reasons Other than Death Disability
or Retirement.  In the event that a Participant terminates his or her employment
with the  Corporation  for any reason other than those set forth in  Subsections
7.8 and 7.9  hereof  during  the  Period  of  Restriction,  then any  shares  of
Restricted  Stock still subject to restrictions at the date of such  termination
shall  automatically  be forfeited  and returned to the  Corporation;  provided,
however, that, in the event of an involuntary termination of the employment of a
Participant by the Corporation, the Committee may, in its sole discretion, waive
the  automatic  forfeiture  of any or

                                      -8-



all  such  shares  and/or  may add  such  new  restrictions  to such  shares  of
Restricted Stock as it deems appropriate.

          7.11  Nontransferability  of Restricted Stock. No shares of Restricted
Stock  granted  under the Plan may be sold,  transferred,  pledged,  assigned or
otherwise  alienated or  hypothecated,  otherwise than by will or by the laws of
descent and  distribution  until the  termination  of the  applicable  Period of
Restriction.   All  rights  with  respect  to  Restricted  Stock  granted  to  a
Participant  under  the  Plan  shall be  exercisable  during  the  Participant's
lifetime only by such Participant.

Section 8.        Beneficiary Designation

          8.1  Beneficiary   Designation.   Each  Participant  and  Non-Employee
Director  under  the Plan  may,  from  time to time,  name  any  beneficiary  or
beneficiaries  (who  may be  named  contingently  or  successively)  to whom any
benefit under the Plan is to be paid in case of the death of the  Participant or
the Non-Employee  Director, as the case may be, before he or she receives any or
all of such benefit.  Each designation will revoke all prior designations by the
same Participant or Non-Employee Director,  shall be in a form prescribed by the
Committee  and  will  be  effective  only  when  filed  by  the  Participant  or
Non-Employee  Director in writing with the Committee  during the lifetime of the
Participant or Non-Employee  Director.  In the absence of any such  designation,
benefits  remaining  unpaid  at the  death of the  Participant  or  Non-Employee
Director,  as the case may be, shall be paid to the estate of the Participant or
Non-Employee Director, as the case may be.


Section 9.        Rights of Employees

          9.1  Employment.  Nothing in the Plan shall interfere with or limit in
any way the right of the Corporation to terminate any  Participant's  employment
at any time nor confer upon any  Participant any right to continue in the employ
of the Corporation.

          9.2 Participation.  No employee shall have a right to be selected as a
Participant or, having been so selected,  to be selected again as a Participant.
The  preceding  sentence  shall not be  construed  or  applied  so as to deny an
employee any Participation in the Plan solely on the basis that the employee was
a Participant in connection with a prior grant of benefits under the Plan.

Section 10.       Administration; Powers and Duties of the Committee

          10.1  Administration.  The  Committee  shall  be  responsible  for the
administration  of the Plan.  The  Committee,  by majority  action  thereof,  is
authorized to interpret the Plan,  to  prescribe,  amend,  and rescind rules and
regulations  relating to the Plan,  to provide  for  conditions  

                                      -9-



and  assurances  deemed  necessary or advisable to protect the  interests of the
Corporation, and to make all other determinations necessary or advisable for the
administration  of the Plan,  but only to the extent not contrary to the express
provisions of the Plan. Determinations,  interpretations,  or other actions made
or taken by the Committee  pursuant to the provisions of the Plan shall be final
and binding and conclusive for all purposes and upon all persons whomsoever. The
grant, amount and terms of Awards to Non-Employee Directors under the Plan shall
be determined as provided in Section 6A of the Plan.

          10.2  Change  of  Control.  Without  limiting  the  authority  of  the
Committee  as provided  herein,  the  Committee,  either at the time  Options or
shares of  Restricted  Stock are granted,  or, if so provided in the  applicable
Option agreement or Restricted  Stock grant, at any time thereafter,  shall have
the authority to accelerate  in whole or in part the  exercisability  of Options
and/or the last day of the Period of Restriction  upon a Change of Control.  The
Option  agreements  and  Restricted  Stock grants  approved by the Committee may
contain  provisions  whereby,  in  the  event  of  a  Change  of  Control,   the
acceleration of the  exercisability of Options and/or the last day of the Period
of  Restriction  may be  automatic  or may be subject to the  discretion  of the
Committee,  depending  on whether  the Change of Control  shall be approved by a
majority  of the  members  of the  Board.  If the  receipt  of any  payment by a
Participant under the circumstances  described above would result in the payment
by the  Participant  of any excise tax  provided for in Section 280G and Section
4999 of the Code, then the amount of such payment shall be reduced to the extent
required to prevent the imposition of such excise tax.

          10.3 Amendment, Modification and Termination of Plan. The Board may at
any  time  terminate,  and from  time to time may  amend  or  modify  the  Plan,
provided,  however,  that no such action of the Board,  without  approval of the
stockholders, may:


          (a)  Increase  the total amount of Stock which may be issued under the
     Plan, except as provided in Subsections 4.1 and 4.3 of the Plan.

          (b)  Increase  the total  number of shares of Stock that may be issued
     under the Plan to any one  Participant,  except as provided in  Subsections
     4.1 and 4.3 of the Plan.

          (c) Change  the  provisions  of the Plan  regarding  the Option  price
     except as permitted by Subsection 4.3.

          (d)  Materially  increase the cost of the Plan or materially  increase
     the benefits to Participants and/or Non-Employee Directors.

          (e) Extend the period during which Options or Restricted  Stock may be
     granted.

                                      -10-



          (f) Extend the maximum  period  after the date of grant  during  which
     Options may be exercised.

          (g) Change the class of  individuals  eligible  to receive  Options or
     Restricted Stock.

No  amendment,  modification  or  termination  of the Plan  shall in any  manner
adversely affect any Options or Restricted Stock  theretofore  granted under the
Plan, without the consent of the Participant.

Section 11.       Tax Withholding

          11.1 Tax Withholding.  Whenever shares of Stock are to be issued under
the Plan, the  Corporation  shall have the power to require the recipient of the
Stock to remit to the Corporation an amount sufficient to satisfy Federal, state
and local withholding tax requirements  prior to issuance of the certificate for
shares of stock.

Section 12.       Requirements of Law

          12.1 Requirements of Law. The granting of Options or Restricted Stock,
and the  issuance  of shares of Stock upon the  exercise  of an Option  shall be
subject to all applicable laws, rules and regulations,  and to such approvals by
any governmental agencies or national securities exchanges as may be required.

          12.2 Governing Law. The Plan, and all agreements  hereunder,  shall be
construed in accordance with and governed by the laws of the State of Wisconsin.
