SWIFT ENERGY COMPANY

                       1990 NONQUALIFIED STOCK OPTION PLAN
                    (AMENDED AND RESTATED AS OF MAY 13, 1997)

         1.       PURPOSE OF THE PLAN.
                  -------------------

         This Swift  Energy  Company  1990  Nonqualified  Stock Option Plan (the
"Plan") is intended as an  incentive to retain as  independent  directors on the
Board of Directors (the "Board") of Swift Energy  Company,  a Texas  corporation
(the "Company"),  persons of training,  experience and ability, to encourage the
sense of proprietorship of such persons and to stimulate the active interests of
such persons in the  development  and  financial  success of the Company.  It is
further  intended  that options  issued  pursuant to this Plant (the  "Options")
shall constitute  nonqualified stock options within the meaning of Section 83 of
the Internal Revenue Code of 1986, as amended ("Code").

         2.       SHARES AND OPTIONS.
                  ------------------

         Subject to adjustments in Paragraph 8 hereof, a total of 450,000 shares
(the "Shares") of Common Stock,  $.01 par value ("Stock"),  of the Company shall
be subject to the Plan. The Shares subject to the Plan shall consist of unissued
shares or previously  issued shares  reacquired and held by the Company,  or any
corporation or entity in which the Company  directly or indirectly  controls 50%
or more of the total  combined  voting  power of all classes of its stock having
voting power (any such corporation or entity,  a "Subsidiary"),  and such number
of Shares shall be and hereby is reserved for sale for such purpose. Any of such
Shares that may remain unsold and that are not subject to outstanding Options at
the  termination  of the Plan shall cease to be reserved  for the purpose of the
Plan, but until termination of the Plan the Company shall at all times reserve a
sufficient  number of Shares to meet the  requirements  of the Plan.  Should any
Option  expire  or be  cancelled  prior  to its  exercise  in full,  the  Shares
theretofore subject to such Option may not again be subjected to an Option under
the Plan.

         3.       FORMULA FOR AUTOMATIC GRANT OF OPTIONS.
                  --------------------------------------

                  (a) Options  automatically  shall be granted to those  persons
who, as of the dates set forth in Section 3(b) below,  are (i)  directors of the
Company,  (ii) are not employees of the Company or a  Subsidiary,  and (iii) are
not eligible, and have not been eligible for at least one year prior to becoming
a nonemployee  director of the Company, to receive any award under the Company's
1987 Incentive Stock Option Plan, the Company's 1990 Stock  Compensation Plan or
any other stock  option plan of the Company that is  administered  by any person
having  discretion  with  respect to the  selection of  participants  and/or the
amount of awards (any person  satisfying all three  requirements  is hereinafter
referred to as a  "Director").  Each  person to whom an Option is granted  under
this Plan,  or any  successor  to the rights of such  person  under this Plan by
reason of transfer from the original grantee,  hereafter shall be referred to as
an "Optionee." Each Option shall be evidenced by an option agreement,  in a form
specified  by  the  Board,   containing   terms  and  conditions  that  are  not
inconsistent with this Plan or applicable laws ("Option Agreement"). The Options
automatically  granted to  Directors  under this Plan  shall be in  addition  to
regular  director's  fees or  other  benefits  with  respect  to any  Director's
position with the Company or its  Subsidiaries.  Neither the Plan nor any Option
granted  under the Plan shall  confer  upon any person any right to  continue to
serve as a Director.

                  (b) Subject to Section 3(c) below, on the date (any such date,
an  "Eligibility  Date") on which an  individual  first  becomes a Director  for
purposes of this Plan (but in no event earlier than April 1, 1991,  unless on an
earlier date the Company  determines,  through an  administrative  regulation or
position or based upon an opinion of counsel to the Company,  that each Director
is a  "disinterested  person"  within the meaning of Rule 16b-3 or any successor
rule ("Rule 16b-3")  promulgated under the Securities  Exchange Act of 1934 (the
"Exchange  Act")),  such  Director  shall  automatically  receive an Option with



                                        1





respect to 10,000 Shares.  Thereafter,  each individual who is a Director on the
date  after  any  subsequent  annual  meeting  of  shareholders  of the  Company
occurring  more than eleven (11) months after his or her  Eligibility  Date (any
such date, an "Option  Date"),  on the day following  such annual  meeting shall
automatically  receive an Option with  respect to 5,000  Shares,  subject to the
Option Maximum set forth in Section 3(c) below.  Options  automatically  granted
pursuant to this Section 3(b) are  exercisable  in  installments  as provided in
Section 6(a) below.

                  (c) Notwithstanding  any provision herein to the contrary,  no
Director shall be automatically granted any Option which, if considered together
with all other  outstanding  and  unexercised  options  granted  by the  Company
hereunder or pursuant to any other Company plan ("Outstanding  Options"),  would
entitle  such  Director to purchase  more than  60,000  shares of the  Company's
common stock ("Option Maximum"). On any Eligibility Date or Option Date on which
the automatic  grant of Options  pursuant to Section 3(b) above would exceed the
Option Maximum for a Director,  the number of Shares in respect of which Options
shall be  automatically  granted  hereunder  shall be reduced (or eliminated) so
that the Director's  shares of all Company stock covered by Outstanding  Options
shall  not  exceed  the  Option  Maximum.  In the event  that any such  Director
subsequently  exercises any of his or her Outstanding Options to purchase shares
of the  Company's  stock,  the  shares  purchased  thereby  shall no  longer  be
considered to be Outstanding Options for purposes of the Option Maximum.

         4.       OPTION PRICE.
                  ------------

                  (a) Each Option  shall have an exercise  price for the related
Shares that is equal to the fair market value of such Shares  (determined as set
forth in Section 4(b) below) on the date the Option is granted.

                  (b) The fair  market  value of a Share  on a  particular  date
("Fair Market Value") shall be (i) the highest closing price of the Stock on any
established  national  exchange or exchanges  or, if no sale of Stock is made on
such day,  the next  preceding  day on which there was a sale of such stock,  or
(ii) if the  Stock is not  listed on an  established  stock  exchange,  the mean
between the closing  high bid and low asked  quotations  of the Stock in the New
York  over-the-counter  market  as  reported  by  the  National  Association  of
Securities Dealers, Inc. for such date.

         5.       OPTION PERIOD.
                  -------------

                  The Options granted under this Plan shall be for a term of ten
(10) years from the date of granting of each Option.

         6.       EXERCISE OF OPTIONS; CERTAIN CONDITIONS TO GRANT.
                  ------------------------------------------------

                  (a) An Option shall be exercisable in installments as provided
in the Option  Agreement;  provided,  however,  no Options shall be  exercisable
prior  to  the  first  anniversary  date  of the  date  of  grant  (hereinafter,
"Anniversary  Date").  An Option may be exercised as to twenty  percent (20%) of
the Shares covered thereby beginning on the first Anniversary Date;  thereafter,
an  additional  twenty  percent  (20%) of Shares  subject to the Option shall be
exercisable  as of the  Anniversary  Date in each of the  following  four  years
except as otherwise provided in Sections 6(f), 6(g), 6(h) and 9 below.

                  (b)  Subject to  applicable  exercise  restrictions  set forth
herein, Options may be exercised,  in whole or in part, by giving written notice
of exercise to the Company specifying the number of Shares to be purchased.  The
notice  shall be  accompanied  by payment  in full of the  purchase  price.  The
purchase  price  may be paid by any of the  following  methods,  subject  to the
restrictions set forth in Section 6(c) hereof:



                                        2





           (i) in cash,  by certified or cashier's  check,  by money order or by
         personal  check (if  approved  by the Board) of an amount  equal to the
         aggregate purchase price of the Shares to which such exercise relates;

           (ii) if  acceptable  to the  Board,  by  delivery  of shares of Stock
         already  owned  by the  Optionee,  which  shares,  including  any  cash
         tendered therewith,  have an aggregate Fair Market Value (determined as
         of the date  preceding  the Company's  receipt of the exercise  notice)
         equal to the  aggregate  purchase  price of the  Shares  to which  such
         exercise relates; or

           (iii) if  acceptable  to the Board,  by delivery to the Company of an
         exercise  notice that requests the Company to issue to the Optionee the
         full number of Shares as to which the Option is then exercisable,  less
         the  number  of  Shares  that  have  an  aggregate  Fair  Market  Value
         (determined  as of the date  preceding  the  Company's  receipt  of the
         exercise notice) equal to the aggregate purchase price of the Shares to
         which such exercise relates.

                  (c)  Notwithstanding  the foregoing  payment  provisions,  the
Board may refuse to  recognize  the method of exercise  selected by the Optionee
(other than the method of  exercise  set forth in Section  6(b)(i)),  if, in the
opinion of counsel to the  Company,  (i) the  Optionee is, or within the six (6)
months  preceding such exercise was, subject to reporting under Section 16(a) of
the Exchange Act, and (ii) there is a substantial  likelihood that the method of
exercise selected by the Optionee would subject the Optionee to substantial risk
of liability under Section 16 of the Exchange Act.

                  (d) In addition  to the  alternative  methods of exercise  set
forth in Section  6(b)  above,  either the  Optionee or the Company may elect to
have the Company  withhold from the Shares to be delivered  upon exercise of the
Option the number of Shares (Based on the Fair Market Value of such Shares as of
the date  preceding  the  Company's  receipt  of the  exercise  notice)  that is
necessary to satisfy any withholding  taxes  attributable to the exercise of the
Option.  Such election shall be made by the Optionee,  if at all, at or prior to
the time the exercise notice is delivered to the Company and by the Company,  if
at all, within 10 days after receipt of the exercise  notice.  If withholding is
made in Shares  pursuant  to the method set forth  above,  the Company may grant
"Reload  Option(s)" (as defined in Section 6(e) below) on the terms specified in
Section  6(e)  below  for the  number of Shares  withheld.  Notwithstanding  the
foregoing  provisions,  an  Optionee  may  not  elect  to  satisfy  his  or  her
withholding tax obligation in respect of any exercise as contemplated  above if,
in the opinion of counsel to the Company, (i) the Optionee is, or within the six
(6) months preceding such exercise was, subject to reporting under Section 16(a)
of the Exchange Act, (ii) there is a substantial likelihood that the election or
timing  of the  election  would  subject  the  holder to a  substantial  risk of
liability under Section 16 of the Exchange Act, and (iii) such withholding would
have an adverse tax or accounting effect to the Company.

                  (e) Whenever the  Optionee  holding any Option (the  "Original
Option")  outstanding  under this Plan (including any "Reload  Options"  granted
under the  provisions  of this Section 6(e))  exercises the Original  Option and
makes payment of the option price by tendering Shares  previously held by him or
her pursuant to Section 6(b)(ii)  hereof,  or by taking delivery of a net number
of shares of common  stock  upon  exercise  of an  option  pursuant  to  Section
6(b)(iii) hereof,  then the Company may grant a new option (the "Reload Option")
for the  number  of  additional  Shares  that is equal to the  number  of shares
tendered by the Optionee  (or credited on behalf of the  Optionee) in payment of
the option  price for the  Original  Option  being  exercised.  All such  Reload
Options granted hereunder shall be on the following terms and conditions:

            (i) The Reload  Option  exercise  price per share shall be an amount
         equal to the then current Fair Market Value per share of the  Company's
         Common Stock, determined as of the date of the Company's receipt of the
         exercise notice for the Original Option;



                                        3





            (ii) The option exercise period shall expire,  and the Reload Option
         shall no longer be exercisable,  on the expiration of the option period
         of the  Original  Option or two (2) years from the date of the grant of
         the Reload Option, whichever is later;

           (iii) Any Reload  Option  granted  under this Section 6(e) shall vest
         and  first  become  exercisable  one (1)  year  following  the  date of
         exercise of the Original Option; and

            (iv) All other terms of Reload Options  granted  hereunder  shall be
         identical  to the terms and  conditions  of the  Original  Option,  the
         exercise of which gives rise to the grant of the Reload Option.

                  (f) Notwithstanding  any provision herein to the contrary,  in
the event a Director is unable to  continue as a Director  with the Company as a
result of his or her total and  permanent  "disability"  (as  defined in Section
22(e)(3)  of the Code),  he or she may,  but only  within the period of time one
year from the date he or she becomes disabled (but not later than the expiration
of the term of the  Option),  exercise his or her Option  (including  any Reload
Option) to the extent he or she was  entitled to exercise it at the date of such
termination.  To the extent the Optionee was not entitled to exercise the Option
at the date of the  termination,  or if he or she does not exercise  such Option
(which he or she was entitled to exercise) within the time specified herein, the
Option shall terminate.

                  (g) In the event of the death of an Optionee during his or her
term of service as a Director of the  Company,  to the extent the  Optionee  was
entitled to  exercise  the Option at the time of his or her death the Option may
be exercised within a one-year period following the date of death (but not later
than the expiration of the term of the Option) by the Optionee's  estate or by a
person who acquired the right to exercise the Option by bequest or  inheritance.
To the extent the  Optionee  was not entitled to exercise the Option at the date
of his or her death, the Option shall terminate.

                  (h) Upon termination of an Optionee's service as a Director of
the  Company  (for any  reason  other  than death or  disability),  Options  not
theretofore vested and exercisable shall be forfeited;  provided,  however, that
if the Company  terminates the Optionee's  service as a Director one-half of the
Shares  subject to the Option  that were not  theretofore  exercisable  shall be
immediately exercisable as of the date of termination of such service.

         7.       TRANSFERABILITY.
                  ---------------

         The Board may,  in its  discretion,  authorize  all or a portion of any
Option to be on terms which permit  transfer by the Optionee to (i) a retirement
or pension plan for the benefit of the  Optionee,  (ii) the spouse,  children or
grandchildren of the Optionee  ("Immediate  Family  Members"),  (iii) a trust or
trusts  for the  exclusive  benefit of such  Immediate  Family  Members,  (iv) a
charitable  trust or trusts  created or  controlled  by the  Optionee,  or (v) a
partnership  in which  such  Immediate  Family  Members  are the only  partners,
provided that (x) there may be no consideration  for any such transfer,  (y) the
Option  Agreement must be approved by the Board,  and the Option Agreement or an
amendment  thereto  must  expressly  provide  for  transferability  in a  manner
consistent  with this  Section,  and (z)  subsequent  transfers  of  transferred
Options  shall be prohibited  except to a transferee to whom the Optionee  could
have transferred the Option pursuant to this Section 7 or by will or the laws of
descent and distribution. Following transfer, any such Options shall continue to
be subject to the same terms and conditions as were applicable immediately prior
to transfer,  provided that for all purposes hereof the term "Optionee" shall be
deemed to refer to the transferee.

         8.       ADJUSTMENTS.
                  -----------

         (a) The existence of the Plan and the Options  granted  hereunder shall
not  affect  or  restrict  in any way the  right or  power  of the  Board or the



                                        4





shareholders   of  the   Company   to  make   or   authorize   any   adjustment,
recapitalization,  reorganization  or  other  change  in the  Company's  capital
structure or its business, any merger or consolidation of the Company, any issue
of bonds, debentures, preferred or prior preference stocks ahead of or affecting
the Company's Stock or the rights thereof, the dissolution or liquidation of the
Company,  or any sale or transfer of all or any part of its assets or  business,
or any other corporate act or proceeding.

         (b) In the event of any change in capitalization affecting the Stock of
the Company, such as a stock dividend,  stock split,  recapitalization,  merger,
consolidation,   split-up,  combination,  exchange  of  shares,  other  form  of
reorganization,  or any other  change  affecting  the Stock,  the Board,  in its
discretion,  may make proportionate  adjustments it deems appropriate to reflect
such change with respect to (i) the maximum  number of shares of Stock which may
be sold or awarded to any  Optionee,  (ii) the number of shares of Stock covered
by each  outstanding  Option,  and (iii) the price per share in  respect  of the
outstanding Options.  Notwithstanding the foregoing, the Board may only increase
the  aggregate  number of shares of Stock for which Options may be granted under
the Plan  solely to reflect the change,  if any,  of the  capitalization  of the
Company.

         9.       CHANGE OF CONTROL.
                  -----------------

                  (a) In the event of a Change of Control (as defined in Section
9(b)  below) of the  Company,  and  except as the  Board may  expressly  provide
otherwise in  resolutions  adopted  prior to the Change of Control,  all Options
then outstanding  shall become fully exercisable as of the date of the Change of
Control; provided,  however, that no Option which has been outstanding less than
one (1)  year on the date of the  Change  of  Control  shall  be  afforded  such
treatment.

                  (b) A "Change  of  Control"  shall be deemed to have  occurred
upon the occurrence of any one (or more) of the following  events,  other than a
transaction  with another  person  controlled by the Company or its officers and
directors,  or a  benefit  plan or  trust  established  by the  Company  for its
employees:

            (i) Any person,  including a group as defined in Section 13(d)(3) of
         the Exchange Act, becomes the beneficial owner of shares of the Company
         with  respect to which 40% or more of the total number of votes for the
         election of the Board may be cast;

            (ii) As a result of, or in connection  with,  any cash tender offer,
         exchange offer, merger or other business combination, sale of assets or
         contested  election,  or  combination  of the above,  persons  who were
         directors of the Company immediately prior to such event shall cease to
         constitute a majority of the Board;

            (iii) The  stockholders  of the Company  shall  approve an agreement
         providing  either for a transaction  in which the Company will cease to
         be an  independent  publicly  owned  corporation or for a sale or other
         disposition of all or substantially all the assets of the Company; or

            (iv) A tender  offer or  exchange  offer is made for  shares  of the
         Company's Stock (other than one made by the Company), and forty percent
         (40%)  of the  Company's  outstanding  shares  of  Stock  are  acquired
         thereunder.

         10.      SECURITIES LAWS RESTRICTIONS.
                  ----------------------------

         Whether or not the  Options  and  Shares  covered by the Plan have been
registered under the Securities Act of 1933, as amended,  each person exercising
an Option under the Plan may be required by the Company to give a representation
in writing  that he or she is  acquiring  Shares for his or her own  account for
investment  and  not  with a view  to,  or for  sale  in  connection  with,  the
distribution  of  any  part  thereof.  As a  condition  of any  transfer  of the
certificate  evidencing  Shares,  the Board may obtain such other  agreements of
undertakings,  if any,  that it may deem  necessary  or  appropriate  to  assume



                                        5





compliance   with  any  provisions  of  the  Plan  or  any  law  or  regulation.
Certificates  for  Shares  delivered  under  the  Plan  may be  subject  to such
stock-transfer  orders and other  restrictions  as the Board may deem  advisable
under the rules,  regulations,  and other  requirements  of the  Securities  and
Exchange Commission, any stock exchange upon which the Stock is then listed, and
any applicable Federal or state securities laws. The Board may cause a legend or
legends to be put on any such certificates to refer to those restrictions.

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

                  (a)  Except as set forth in  Sections  11(b),  11(c) and 11(d)
below,  without shareholder  approval the Board may amend,  suspend or terminate
the  Plan  for the  purpose  of  meeting  or  addressing  any  changes  in legal
requirements  or for any other  purpose it deems to be in the best  interests of
the Company if permitted by law.

                  (b) Without the  approval of the  shareholders,  the board may
not make any amendment to the Plan for which shareholder approval is required by
(i) any rules for listed companies promulgated by any national stock exchange on
which the Company's stock is traded or (ii) any other applicable law.

                  (c)   Notwithstanding   Sections  11(a)  and  11(b)  under  no
circumstances may the Board amend,  alter,  discontinue or terminate the Plan so
as to impair the vested rights of Optionees under any Option theretofore granted
under the Plan.

                  (d)  Notwithstanding  Sections 11(a) and 11(b), the provisions
in Sections 3(a) and 3(b) regarding  eligibility and automatic grants of options
under the Plan shall not be amended more than once every six (6) months,  except
for such amendments as may be necessary to comply with applicable  provisions of
the Code or the rules and regulations promulgated thereunder.

         12.      GOVERNMENT REGULATIONS.
                  ----------------------

required.

         13.      COSTS OF PLAN.

         16.      INTERPRETATION.
                  --------------

                  (a) If any  provision  of the  Plan  is held  invalid  for any
reason,  such holding  shall not affect the  remaining  provisions  hereof,  but

been included in the Plan.

         17.      SECTION 83(B) ELECTION.

         If as a result of exercising  an Option,  an Optionee  receives  Shares
that  are  subject  to  a  "substantial   risk  of   forfeiture"   and  are  not
"transferable"  as those terms are defined for purposes of section  83(a) of the
code, then such Optionee may elect under Section 83(b) of the Code to include in
his gross income,  for his taxable year in which the Shares are  transferred  to
him,  the excess of the fair market value of such Shares at the time of transfer
(determined  without regard to any restriction other than one which by its terms
will never lapse),  over the amount paid for the Shares.  If the Optionee  makes
the section 83(b)  election  described  above,  the Optionee shall (i) make such
election in a manner that is satisfactory to the Board, (ii) provide the Company
with a copy of such election,  (iii) agree to promptly  notify the Company if an
Internal  Revenue Service or state tax agent,  on adult or otherwise,  questions
the  validity  or  correctness  of such  election  or of the  amount  of  income
reportable on account of such  election,  and (iv) agree to such  withholding as
the Board may reasonably require.
