                    PRELIMINARY COPY -- SUBJECT TO COMPLETION
                             DATED NOVEMBER 30, 1998

                      [POOL ENERGY SERVICES CO. LETTERHEAD]

                                December __, 1998

Dear Shareholders:

     We are  writing  to you  about the  continued  takeover  tactics  by Nabors
Industries Inc. in its effort to buy Pool Energy Services Co at a bargain price.
Nabors has already started a creeping acquisition by purchasing over 10% of your
Company in the open market without  paying any premium.  Now Nabors is resorting
to another takeover tactic by calling a Special Meeting of shareholders of Pool.

     At the Special Meeting,  Nabors will propose that the shareholders  adopt a
non-binding  resolution  recommending  that Pool's Board arrange for the sale of
Pool and take all necessary actions to effect such sale, including,  among other
things,  entering into merger  negotiations  with Nabors and any other qualified
bidder offering a higher price per share than Nabors.

     Nabors knows that even if the resolution passed, your Board of Directors is
not  required  to take any  action  whatsoever  with  respect to the sale of the
Company. Given this, it is clear that Nabors has called the Special Meeting as a
tactic  designed to disrupt the Company and  distract it from  implementing  its
strategic plan.

     For the reasons set forth in this Proxy Statement, your Board believes that
the  Nabors  resolution  is not in the  best  interests  of the  Company  or its
shareholders,  particularly  at this time with  depressed  prices  for  oilfield
service companies. The Board recommends that you reject the Nabors resolution by
voting AGAINST such proposal on the enclosed GOLD proxy card.

     Your Board asks you to  consider  carefully  the matters  discussed  in the
accompanying  proxy  materials  and  our  letter  dated  November  27,  1998  in
evaluating the Nabors resolution.

     To vote your proxy in opposition to the Nabors  resolution mark, sign, date
and return the enclosed GOLD proxy card as soon as possible. Please help us send
a strong message to Nabors to stop its disruptive  takeover tactics.  Your Board
unanimously  believes Nabors is not acting in the best interests of all the Pool
shareholders.  WE URGE  YOU NOT TO SIGN ANY  PROXY  CARD  YOU MAY  RECEIVE  FROM
NABORS.

     We  believe  our  Company's  prospects  are  excellent  and think  that our
shareholders,  not Nabors, should be the beneficiaries as our industry recovers.
It would not be prudent  or  responsible  for our Board to let  Nabors  reap the
benefits  that  rightly  belong to each of you.  We  appreciate  your  continued
support and interest in the affairs of the Company.

                                                Sincerely,

                                                /s/ J.T. Jongebloed

                                   BACKGROUND

     In late 1993,  Nabors began  acquiring  shares of the common stock,  no par
value per share of the Company (the "Common Stock").  In September 1993,  Eugene
M.  Isenberg,  Chairman  and Chief  Executive  Officer of Nabors,  and two other
directors of Nabors had dinner with James T.  Jongebloed and Ernest J. Spillard,
both executive  officers of the Company.  Nabors'  representatives  expressed an
interest in pursuing  joint  purchasing or other  arrangements  that could be of
mutual  benefit.  No specific  proposals were discussed and no specific  further
actions resulted from that meeting.

     In early 1994,  the Company  developed  a  strategic  plan (the  "Strategic
Plan") designed to further strengthen its competitive  position and market share
in the  oilfield  services  industry  in order to  achieve  growth in  revenues,
earnings and EBITDA (earnings (loss) before interest, income taxes, depreciation
and amortization,  and minority interest).  Key components of the plan included:
(i) expanding  opportunities in existing core market areas through  acquisitions
that  result  in  consolidation   savings;  (ii)  upgrading  and  enhancing  the
capabilities of the Company's  existing fleet and building  certain  specialized
rigs and equipment to operate in markets with high levels of activity and strong
pricing fundamentals;  (iii) entering new foreign markets that offer significant
development and production activity;  and (iv) offering additional core services
and equipment  that  complement  the Company's  businesses in its existing field
locations.  The Strategic Plan was adopted on May 5, 1994 when the closing price
of the Company's Common Stock was $7.25.

     During  April 1994,  Mr.  Isenberg  telephoned  Mr.  Jongebloed  to inquire
whether he had any interest in another dinner meeting to examine alternatives of
working together for the mutual benefit of each company's  shareholders,  but no
further  discussions  took place at that time. On May 26, 1994,  Nabors reported
that  it  had  acquired  867,500  shares  of  Common  Stock  (then  constituting
approximately  6.4% of the  outstanding  shares).  On June 8, 1994,  the Company
announced that it had adopted its  shareholder  rights  agreement.  Later in the
summer of 1994, Mr.  Isenberg and two other  representatives  of Nabors met with
Mr.  Jongebloed  and the Company's  investment  advisors to discuss  whether the
Company  had any  interest  in  pursuing  a  merger,  joint  venture,  or  other
combination.  Mr. Jongebloed  indicated that the Company was of the opinion that
its shareholders  would be better served by the  implementation of the Strategic
Plan.

     Since the adoption of the  Strategic  Plan,  the Company has  implemented a
number of key initiatives.  These include  acquiring  additional  well-servicing
operations,  principally in  California,  West Texas,  and the Rocky  Mountains;
acquiring full ownership of the operation in Alaska in which Pool had previously
been a minority  partner;  increasing  the  Company's  participation  in foreign
markets;  and  acquiring a company  that  operates a fleet of  offshore  support
vessels in the Gulf of Mexico.  The Company also enhanced its rig fleet through,
among other  things,  the  construction  of new rigs and the major  upgrading of
others.  During  this  period,  the  Company's  revenues,  EBITDA  and  earnings
increased substantially, and the market price of the Common Stock reflected this
improved financial  performance,  peaking at over $40.00 per share on October 9,
1997.

     Since October 1997,  oil prices,  which are the  predominant  driver of the
Company's  business  activity level, have declined more than 45%. Oil prices are
now at low levels not seen in over ten  years.  As a result,  the prices for the
stocks  of  many  oilfield  services  companies,   including  the  Company,  are
significantly depressed.

     In the summer of 1998,  after  declining oil prices had begun to materially
affect the price of the Common Stock, Nabors approached an investment banker for
the Company regarding a possible  combination of the Company and Nabors.  Nabors
was told that the Company's  management was not open to pursuing  discussions at
that  time,  particularly  in view of the then low  market  price for the Common
Stock.

     On October 12, 1998, Mr. Isenberg sent the following letter to the Board of
the Company (the "October 12th Letter"):

                                        October 12, 1998

                                                                    CONFIDENTIAL

     The Board of Directors of
     Pool Energy Services Co.
     10375 Richmond Avenue
     Houston, Texas 77042

     Dear Mr. Jongebloed:

          We recently raised with your outside advisor the potential benefits to
     our  respective  stockholders,  employees and customers of a combination of
     our two  companies.  While you have informed us that you believe now is not
     an  appropriate  time  for a  combination,  we  believe  that  the  current
     environment  causes the combination to make eminent business sense for both
     companies.

          The strategic direction of both Pool and Nabors is complementary. Each
     company operates  drilling and workover platform rigs in the Gulf of Mexico
     and  internationally  as well as land  drilling  operations  in Alaska  and
     internationally, including Saudi Arabia. A combination of the two companies
     can lead to  economies  of scale that  offer the  prospect  of  significant
     purchasing,  operating and other  efficiencies.  Nabors' offshore  presence
     would also offer  significant  opportunities  for marketing  Pool's Sea Mar
     Fleet.

          In times of  uncertainty,  stockholders,  employees and customers will
     benefit from a larger,  stronger and  better-capitalized  company.  I think
     most  industry  observers  would  also agree  with this  premise.  For this
     reason, we propose putting our two companies together and believe that such
     a  combination  is in  the  best  interest  of  the  stockholders  of  both
     companies.

          We would like to submit to your Board a merger  proposal  under  which
     Nabors would  acquire all of the  outstanding  shares of Pool at a price of
     $12.50 per share. This consideration would be payable at least 51% in stock
     (to preserve tax free  treatment) and the remainder in cash. This structure
     offers those stockholders  interested in retaining a long-term position the
     prospect of  participating  in future upside  prospects that are materially
     enhanced as a result of the  transaction  and of growth with the benefit of
     an over 50 percent premium.  At the same time,  stockholders  electing cash
     will recognize an immediate substantial premium over current market.

          Your  management  team has  clearly  been a major  contributor  to the
     Company's  success.  We believe that there will be continuing roles for key
     management   that  will  offer  greater   responsibilities   and  increased
     opportunities in the context of a substantially larger company.

          While we know your  business  well,  our  proposal  is based on public
     information.  If you can  demonstrate  additional  value, we would consider
     offering a higher price.

          Nabors' Board of Directors has unanimously approved our proposal.  Our
     financial  advisors  and bank  lenders  have  assured us that  financing is
     available to meet all transaction  requirements.  Our legal advisors and we
     have also  carefully  studied any  potential  antitrust  issues raised by a
     combination of our two  companies,  and we are confident that any necessary
     approvals for the transaction can be obtained  without any undue delay. Our
     proposal  is of  course  subject  to  negotiation  of a  definitive  merger
     agreement  containing  customary terms and  conditions.  We are prepared to
     immediately commence negotiating a definitive acquisition agreement between
     our companies and to consummate the agreement in an expeditious manner.

<PAGE>

          My intent in sending  this letter is to provide  you with  information
     about our contemplated  proposal and to express our desire to work together
     with you to structure a  transaction  acceptable  to your Board.  We do not
     believe this letter  requires you to make any public  disclosure  and we do
     not intend to make it public at this time. We would hope that at this point
     you would be prepared immediately to commence discussions on a confidential
     basis between us.

          We would like to meet with you and your representatives to discuss our
     proposal and to answer any questions  that you may have.  Please contact my
     office  (281-775-8077)  to let me know when we can get  together.  We would
     appreciate  receiving your views as to our  contemplated  proposal no later
     than October 23, 1998.

                                        Sincerely,

                                        /s/ Eugene M. Isenberg
                                        Eugene M. Isenberg
                                        Chairman and Chief Executive Officer

     On October 12,  1998,  Mr.  Jongebloed  shared the October 12th Letter with
other members of management,  as well as with the Company's  legal and financial
advisors.  A meeting of the Board was held on October 19,  1998 to consider  the
October 12th Letter. At that meeting,  the Board,  among other things,  reviewed
the October 12th Letter, heard presentations as to fiduciary responsibilities of
the Board in considering acquisition proposals, such as the one set forth in the
October  12th  Letter,  and were  advised  as to the work that  would need to be
performed by the Company's  advisors to assist the Board in its consideration of
the  proposal  made by Nabors  and the  various  alternatives  available  to the
Company.

     At that time, the Board  concluded  that,  given the values inherent in the
Company's  business and the long-term  strategies  being  implemented to improve
shareholder  value,  the Nabors  proposal  was not in the best  interests of the
Company and its  shareholders.  In  particular,  the Board  determined  that the
Company's  strategic  initiatives  as well  as the  long-term  interests  of the
Company and its shareholders would be best served by the continued  independence
of the Company.

     As  a result, on October 26, 1998, Mr. Jongebloed sent the following letter
to Mr. Isenberg:

                                                      October 26, 1998

     CONFIDENTIAL

     Mr. Eugene M. Isenberg
     Chairman and Chief Executive Officer
     Nabors Industries, Inc.
     515 West Greens Road, Suite 1200
     Houston, Texas 77067-4525

     Dear Mr. Isenberg:

          My fellow  directors and I have carefully  considered your October 12,
     1998 letter,  and I have been  instructed  by our Board to tell you that we
     are not interested in pursuing the discussions with your company  suggested
     in that letter.  We want you to know that this  decision is  unanimous  and
     unequivocal.

          As you may know, our Company is committed to the implementation of its
     own strategic plan,  which is designed to capitalize on  opportunities  for
     the  Company  and to increase  shareholder  values  over the long term.  We
     believe the results of these efforts to date have been impressive.  But for
     the current unexpected downturn in our industry, which is the worst in many
     years,  we believe  our stock price  would  better  reflect the efforts and
     achievements of our Board and management.

                                        J.T. Jongebloed

On October 28,  1998,  Nabors  sent the  following  letter to the  Company  (the
"October 28th Letter"):

                                                      October 28, 1998

                                                                    CONFIDENTIAL

     The Board of Directors of
     Pool Energy Services Co.
     10375 Richmond Avenue
     Houston, Texas 77042

     Dear Mr. Jongebloed:

          On October 12, 1998, I wrote to you proposing a combination  of Nabors
     and Pool in which Nabors  would  acquire all of the  outstanding  shares of
     Pool for consideration consisting of 51% Nabors stock and 49% cash, with an
     implied value at that date of $12.50 per Pool share. This offer represented
     a 77% premium to Pool's  closing  stock price of $7.06 per share on October
     9, 1998,  the last trading day prior to our proposal.  On October 26, 1998,
     we  received a letter  from you  stating  that Pool was not  interested  in
     pursuing discussions with Nabors. In view of the superior value inherent in
     our proposal,  we were  surprised  that your Board of Directors  could have
     concluded  unanimously and unequivocally  not to discuss our proposal.  Had
     our  proposal  been  accepted on October 12, your  shareholders  would have
     received  consideration  with a blended  value today of $14.72 based on the
     ratios  implied by our offer price of $12.50 and Nabors'  closing  price on
     October 9 of $13.25.  We  continue to believe  that a business  combination
     based  on  these  values  is  in  the  best   interests  of  Pool  and  its
     shareholders.

          In your letter,  you refer to Pool's commitment to the  implementation
     of its own strategic plan, which is designed to increase  shareholder value
     over the long-term.  We are convinced that this plan cannot  outperform the
     benefits of a combination  of Pool and Nabors given the high  fragmentation
     of our industry,  the economies of scale which will be realized through the
     combination and the enhanced capital structure of the combined entities. As
     a result,  we believe that a combination of our companies will maximize the
     long-term value to be realized by your shareholders.

          Given the strong  benefits of a  combination  of Pool and  Nabors,  we
     encourage  you to  reevaluate  our proposal to enter into a merger in which
     Nabors  would   acquire  all  of  the   outstanding   shares  of  Pool  for
     consideration  equal to 0.481  Nabors  shares  and  $6.125 in cash for each
     outstanding  Pool share.  As stated  above,  this offer  implies a value of
     $14.72 per Pool share based on Nabors'  closing  stock price on October 27,
     1998.  In  addition,  as we  indicated  in our  letter of  October  12, our
     proposal  is  based  on  public  information  and,  if you can  demonstrate
     additional value, we would consider offering a higher price.

          We are hopeful that Pool's  management  and Board of Directors want to
     act in the best  interests of the  company's  shareholders.  We also firmly
     believe  that your  shareholders  would  welcome our  proposal,  and we are
     committed  to  affording  them  the  opportunity  to do  so.  Based  on the
     unusually high trading volume in Pool's shares subsequent to our October 12
     letter, it is in both our interests to discuss this matter quickly.  I will
     call you tomorrow to discuss our proposal.

                                        Sincerely,

                                        /s/ Eugene M. Isenberg
                                        Eugene M. Isenberg
                                        Chairman and Chief Executive Officer

     Mr. Isenberg called Mr.  Jongebloed on October 29, 1998, but Mr. Jongebloed
was unable to return the call that day.  The next  morning,  October  30,  1998,
Nabors issued a press release setting forth, among other things, the text of all
prior correspondence and announcing the merger proposal.

     On October 30, 1998, the Company sent the following letter to Nabors:

                                        October 30, 1998

     Mr. Eugene M. Isenberg
     Chairman and Chief Executive Officer
     Nabors Industries, Inc.
     515 West Greens Road, Suite 1200
     Houston, Texas 77067-4525

     Dear Mr. Isenberg:

          As I told you in my October 26 letter to you,  our Board of  Directors
     carefully considered your October 12, 1998 letter and instructed me to tell
     you that we are not  interested  in  pursuing  the  discussions  with  your
     company  suggested  in that  letter.  As I also  said,  this  decision  was
     unanimous and unequivocal.

          As you know, our Company is committed to the implementation of its own
     strategic plan,  which is designed to capitalize on  opportunities  for the
     Company and to increase  shareholder  values over the long term. We believe
     the  results  of these  efforts to date have been  impressive.  But for the
     current  unexpected  downturn in our  industry,  which is the worst in many
     years,  we believe  our stock price  would  better  reflect the efforts and
     achievements of our Board and management.

          It is not surprising that you share our views concerning our Company's
     excellent  prospects,  but our  shareholders  -- not yours -- should be the
     beneficiaries  of our  efforts as our  industry  recovers.  It would not be
     prudent or  responsible  for our Board to let others reap the benefits that
     rightly belong to our shareholders.

                                        Yours very truly,

                                        /s/ J.T. Jongebloed
                                        J.T. Jongebloed

     Contrary to Nabors'  assertions that management of Pool has refused to meet
with Nabors' representatives, representatives of Pool agreed to meet with Nabors
on or about November 13, 1998, to hear what Nabors had to say, on the assumption
that Nabors would agree to abandon its efforts to disqualify  Pool's  counsel on
what  Pool  perceived  to be a  trivial  basis.  Nabors  refused  to  waive  the
disqualification, and Pool was forced to engage new counsel.

     On November 16, 1998, the Company engaged Morgan Stanley & Co. Incorporated
("Morgan  Stanley") to assist the Company in, among other things, the evaluation
and  further  implementation  of  its  growth  strategies  with  the  intent  of
maximizing long-term shareholder value.

     On  November  17,  1998,  a  representative  of  Morgan  Stanley  advised a
representative  of Nabors'  investment banker that Morgan Stanley and Pool's new
counsel  needed  time  to  familiarize   themselves   with  the  Company  before
considering  scheduling any meeting  between  representatives  of Nabors and the
Company.

     On November 23, 1998, Nabors filed preliminary proxy materials  relating to
its request for a Special  Meeting to consider  the Nabors  Resolution.  Also on
that date,  Nabors,  together with one of its  subsidiaries,  requested that the
Company provide,  among other things, copies of the Company's stockholder lists,
daily transfer lists, names of non-objecting  beneficial owners, and all minutes
and other records of meetings and  proceedings  of the Board and each  committee
thereof. The Company is currently evaluating these requests.

     In response to Nabors' filing and a concurrent  press release,  the Company
issued the following press release:

          HOUSTON,  November 23, 1998 -- Pool Energy Services Co.  (NASDAQ:PESC)
     today acknowledged receipt of a notice by Nabors Industries, Inc. (ASE:NBR)
     calling  for a Special  Meeting of  Shareholders  of the Company in January
     1999 "to consider and vote upon a non-binding resolution...recommending the
     sale of the  Company."  James  Jongebloed,  Chairman  and  Chief  Executive
     Officer of the Company,  responded by saying:  "This is another transparent
     attempt by Nabors to pressure  Pool's  Board into  approving a fire sale of
     the Company when the oil industry is at a cyclical low and Pool is strongly
     positioned to optimize value to shareholders as the industry recovers."

          Pool said it is  committed  to the  implementation  of its own  growth
     strategies and the  maximization of shareholder  value. In this connection,
     the Company  announced  that last week it had engaged  Morgan  Stanley Dean
     Witter to assist it in the  evaluation  and further  implementation  of its
     growth  strategies  with the  intent of  maximizing  long term  shareholder
     value.

          Pool Energy Services Co.,  headquartered in Houston,  is a diversified
     energy services company  principally  engaged in providing  well-servicing,
     workover and drilling services and related transportation  services on land
     and offshore in the U.S. and selected international markets.

     The  Board's  position  is very  clear.  On  October  26,  1998,  the Board
unanimously and  unequivocally  communicated  its decision to Nabors that it was
not interested in pursuing the discussions that Nabors had suggested.


                              THE NABORS RESOLUTION

     At the Special  Meeting,  Nabors has stated that it will  propose  that the
shareholders of the Company adopt the Nabors Resolution, which reads as follows:

          RESOLVED,  that the  shareholders  of Pool  Energy  Services  Co. (the
     "Company")  strongly  recommend  that the Board of Directors of the Company
     arrange  for the sale of the  Company  and take all  necessary  actions  to
     effect such sale,  including,  without  limitation,  (i) entering into good
     faith merger  negotiations with Nabors Industries,  Inc. ("Nabors") and any
     other qualified bidder for the Company offering a higher price per share of
     Company common stock than Nabors,  (ii) redeeming the common stock purchase
     rights of the Company granted pursuant to the Rights Agreement, dated as of
     June 7, 1994, between the Company and the First National Bank of Boston and
     (iii) taking all action to approve the sale of the Company  under the Texas
     Business  Corporation  Act (the  "TBCA"),  including,  without  limitation,
     Article  13.03 of the TBCA;  it being  understood  that this  resolution is
     admonitory  only and  that  the  Board of  Directors  of the  Company  must
     exercise its business  judgment in fulfillment  of its fiduciary  duties to
     the shareholders of the Company.


                   REASONS FOR OPPOSING THE NABORS RESOLUTION

     The Board believes that the Nabors Resolution  represents nothing more than
a  takeover  tactic in its  attempt to  acquire  the  Company in a trough of the
business  cycle for  oilfield  service  companies  when the market  price of the
Common  Stock does not, in the opinion of the Board,  appropriately  reflect the
inherent value of the Company. Oil prices are at low levels not seen in over ten
years. Consequently, rig


                                        8

<PAGE>



counts in the U.S.  are also at  cyclical  lows.  The  prices  of many  oilfield
service companies,  including the Company's Common Stock, are therefore severely
depressed. Nabors has chosen this opportune time (from a buyer's perspective) to
put pressure on the Board to sell the Company.

     Although  Nabors'  acquisition  proposal does  represent a premium over the
$11.813  closing price of the Common Stock on October 29, 1998 (the last trading
day immediately  prior to Nabors'  October 30, 1998 press release),  the implied
value of Nabors' proposal as of that date is actually a discount of 48% from the
$27.675  closing  price of the  Common  Stock on April 20,  1998  (which was the
highest  closing  price for the Common  Stock thus far during  1998),  less than
eight months ago.  While  between  October 9, 1997 and October 9, 1998 (the last
trading  day before  Nabors'  October  12th  Letter)  the  closing  price of the
Company's  Common  Stock fell 83% from $40.625 to $7.063,  the closing  price of
Nabors stock dropped 72% from $46.563 to $13.25.


POOL'S GROWTH STRATEGIES TO MAXIMIZE SHAREHOLDER VALUE

     The  Company  developed  its  Strategic  Plan  to  further  strengthen  its
competitive position and market share in the oilfield services industry in order
to achieve  growth in revenues,  EBITDA,  and  earnings.  Key  components of the
Strategic Plan included:

     o    pursuing expansion opportunities in existing core market areas through
          acquisitions that result in consolidation cost savings;

     o    upgrading  and enhancing the  capabilities  of the Company's  existing
          fleet and certain specialized rig equipment to operate in markets with
          high levels of activity and strong pricing fundamentals;

     o    entering new foreign  markets that offer  significant  development and
          production activity; and

     o    offering   additional  services  and  equipment  that  complement  the
          Company's businesses in its existing locations.

     The Company has made  significant  progress  in the  implementation  of its
growth strategies. Between June 1, 1994 and September 30, 1998, the Company:

     o    acquired  additional  land  well-servicing  operations  principally in
          California,  West Texas and the Rocky  Mountains,  including 289 rigs,
          128 oilfield  trucks,  430 fluid storage tanks, six brine and disposal
          wells and seven  coiled  tubing  units,  at an  aggregate  cost of $74
          million;

     o    acquired  full  ownership  of the  operations  in  Alaska in which the
          Company had previously held a minority interest for $12 million;

     o    expanded and enhanced its rig fleet in Alaska,  the Gulf of Mexico and
          offshore California through  constructing,  upgrading and/or acquiring
          three land drilling  rigs,  two platform  drilling  rigs,  one jack-up
          workover rig and one platform  workover  rig, at an aggregate  cost of
          $73 million;

     o    increased  the  participation  of the  Company and its  affiliates  in
          foreign markets,  including Australia,  Argentina,  Malaysia and Saudi
          Arabia,  through various  acquisitions  and other  investments,  at an
          aggregate cost of $53 million; and

     o    acquired  a  company  that  operates  a fleet of 23  offshore  support
          vessels in the Gulf of Mexico for $76  million in cash and 1.5 million
          shares of Common Stock.

     leasehold impairment.

(b)  EBITDA means earnings (loss) before  interest,  income taxes,  depreciation
     and  amortization  and minority  interest.  The Company has included EBITDA
     data  because  it is a  measure  commonly  used  in  the  oilfield  service
     industry. EBITDA is not a measure of financial performance determined under
     generally accepted  accounting  principles,  should not be considered as an
     alternative to net income as a measure of performance or to cash flows as a
     measure of liquidity, and is not necessarily comparable to similarly titled
     measures of other companies.

     Since the  adoption of the  Company's  Strategic  Plan on May 5, 1994,  the
closing price of the Company's Common Stock rose from $7.25 to 40.625 on October
9, 1997, an increase of approximately  460%.  Subsequently,  the decrease in the
price of oil began to adversely affect the trading prices of the Common Stock as
well as the stocks of other oilfield service companies.


THE SHAREHOLDER RIGHTS PLAN

     As part of the Nabors  Resolution,  Nabors  proposes that the  shareholders
vote to advise the Board that it should redeem the common stock purchase  rights
(the  "Rights")  granted  pursuant to the Rights  Agreement  dated as of June 7,
1994,  between the Company and the First  National  Bank of Boston (the  "Rights
Plan").  The Board believes such a redemption would not be in the best interests
of the shareholders or the Company.

     The Rights Plan was designed to provide the Board with negotiating leverage
in dealing  with a  potential  acquiror,  to protect  the  Company  from  unfair
takeover tactics, and to prevent an acquiror from gaining control of the Company
without offering a fair price to all shareholders.

     The Board  believes  that the Rights  Plan was  appropriately  designed  to
protect the  shareholders  from being forced to receive less than optimal  value
for their  shares of Common  Stock.  The  Rights  Plan was  implemented  to help
protect  shareholders  from acquisition  proposals of the type being advanced by
Nabors.  The Board therefore  believes that redeeming the Rights Plan at present
is not in the best interests of the Company or its shareholders.

     The Company's  Board adopted the Rights Plan on June 7, 1994 and declared a
dividend of one Right for each  outstanding  share of the Company's Common Stock
to  shareholders  of record on June 23,  1994.  The  Rights  will trade with the
Company's  Common  Stock until they become  exercisable.  The Rights will not be
exercisable  until ten  business  days  following a public  announcement  that a
person or group has


                                       10

<PAGE>



acquired beneficial ownership 15% or more of the Company's Common Stock or until
ten  business  days  after a person or group  begins a tender  offer  that would
result in beneficial  ownership of 15% of the Common  Stock,  subject to certain
extensions by the Board.

     In the event that an acquiror  becomes a 15% holder of the Company's Common
Stock,  the Rights "flip in" and become rights to buy the Company's Common Stock
at a 50% discount,  and Rights owned by that acquiror  become void. In the event
that the Company is merged and its Common Stock is exchanged or converted, or if
50% or more of the Company's assets or earning power is sold or transferred, the
Rights  "flip  over" and  entitle  the  holders to buy shares of the  acquiror's
common stock at a 50% discount.

     The Rights may be  redeemed  by the  Company for $.01 per Right at any time
until ten business days following the first public announcement that an acquiror
has acquired the level of ownership that triggers the plan. The Rights expire on
June 6, 2004.


APPROVING  THE SALE UNDER ARTICLE THIRTEEN OF THE TEXAS BUSINESS CORPORATION ACT

     In the Nabors  Resolution,  Nabors also proposes that the shareholders vote
to advise  the Board  that it should  take all  actions to approve a sale of the
Company under the TBCA, including without limitation, Article 13.03 of the TBCA.
The Board  believes  that Article  Thirteen of the TBCA  provides the  Company's
shareholders  with  important  protections  from takeover  proposals that do not
result  in the  maximization  of  shareholder  value.  Consequently,  the  Board
believes  that this  portion  of the Nabors  Resolution  is also not in the best
interests of the shareholders or the Company.

     Prior to 1997,  the TBCA, as it applied to public  corporations,  failed to
address  adequately  the protection  afforded to  shareholders  of  corporations
domiciled in Delaware and many other jurisdictions.  Recognizing this, the Texas
Legislature  adopted Article Thirteen of the TBCA which imposes a special voting
requirement for the approval of certain business  combinations and related party
transactions  between  public  corporations  and  affiliated  shareholders.   In
general,  the law  provides,  subject to certain  exceptions,  for a  three-year
moratorium on mergers and share exchanges  between  issuing public  corporations
like the Company and their affiliated  shareholders  (i.e.,  persons who are, or
within the last three years have been the  beneficial  owner of more than 20% of
the  corporation's   then  outstanding   voting  stock)  and  affiliates.   More
particularly,  such  corporations are prohibited,  directly or indirectly,  from
entering  into  or  engaging  in  a  business  combination  with  an  affiliated
shareholder, or any affiliate or associate of the affiliated shareholder, during
the three-year  period  immediately  following the date on which the shareholder
became an affiliated  shareholder (the "share acquisition date") unless: (i) the
combination or the purchase or acquisition of shares is approved by the board of
directors  of  the  corporation  before  the  affiliated   shareholder's   share
acquisition date; or (ii) the combination is approved by the affirmative vote of
the  holders of at least  two-thirds  of the  outstanding  voting  shares of the
corporation  not  beneficially  owned  by  the  affiliated  shareholder  (or  an
affiliate  or  associate  of  the  affiliated  shareholder),  at  a  meeting  of
shareholders  (and not by written consent) duly called for that purpose not less
than six months after the affiliated shareholder's share acquisition date.

     Article 13.06 also provides that in discharging their duties under the TBCA
or otherwise,  the Company's directors, in considering the best interests of the
corporation,  may consider the long-term as well as the short-term  interests of
the  corporation  and its  shareholders,  including the  possibility  that those
interests may be best served by the continued  independence of the  corporation.
Article  Thirteen ensures that the Board may consider  long-term  interests when
evaluating a takeover proposal. In addition,  Article Thirteen does not preclude
the board of directors  from taking other  actions in  accordance  with law, nor
does the board of directors incur liability for elections made or not made under
its provisions.


INDEPENDENT BOARD

     Other than Mr. Jongebloed, who also serves as Chairman, President and Chief
Executive  Officer of the  Company,  the  directors  of the Company are outside,
independent  directors whose compensation as directors is nominal in relation to
both their  responsibilities  and to the valuable services that they perform. To
the extent the directors own, or have rights to acquire, shares of Common Stock,
they share


                                       11

<PAGE>



a common economic  interest with the  shareholders of Pool generally (other than
Nabors  and  its  supporters).   All  of  Pool's  outside   directors  are  both
"independent" and  "disinterested"  as defined in the TBCA. All of the directors
of the Company are seasoned  executives  who have proven  track  records and are
committed to maximizing values for all shareholders.

     The Board has concluded that Nabors'  proposal to acquire Pool on the terms
set forth in Nabors' published letters to the Board is not in the best interests
of all the  Company's  shareholders.  The  independent  directors of the Company
believe  that their  recommendation  against  the Nabors'  acquisition  proposal
should be accorded more weight than Nabors' biased  recommendation in support of
its proposal,  as the Board is convinced that Nabors is primarily  interested in
acquiring Pool at the lowest possible price.


CONSEQUENCES OF ADOPTION OF THE NABORS RESOLUTION

     Since the Nabors  Resolution is non-binding in nature,  its adoption by the
shareholders  of Pool will not obligate the Board to take any specific action in
response  thereto.  At the  present  time the Board  does not intend to take any
specific  action if the Nabors  Resolution is approved,  although the Board will
continue to pursue strategies to maximize  shareholder value over the long term.
A vote for the Nabors Resolution,  unlike a vote on a definitive merger proposal
approved by the Board, has no effect on the nature of a shareholder's investment
in the Company.  Additionally,  if only a majority of the outstanding  shares of
Common  Stock  are  present  and  voting  at the  Special  Meeting,  the  Nabors
Resolution  could be approved by the affirmative vote of the holders of only 25%
of the  outstanding  shares of Common Stock plus one share.  Nabors already owns
approximately  42% of the  shares  required  to achieve  approval  of the Nabors
Resolution   under  these   circumstances.   In   contrast,   Nabors  only  owns
approximately  17% of the  minimum  number  of  shares  required  to  approve  a
definitive merger agreement under Texas law.


CONCLUSION AND RECOMMENDATION

     THE BOARD OF THE COMPANY RECOMMENDS A VOTE AGAINST THE NABORS RESOLUTION BY
MARKING, DATING, SIGNING AND RETURNING THE GOLD PROXY CARD.


                              THE SPECIAL MEETING


GENERAL

     This Proxy Statement is furnished by the Board of the Company in opposition
to the  solicitation  of  proxies  by  Nabors  in  connection  with  the  Nabors
Resolution. Representatives of Nabors and one of its subsidiaries have scheduled
a Special  Meeting of  Shareholders  of the Company to be held at the offices of
the Company, 10375 Richmond Avenue,  Houston, Texas 77042 on January 12, 1999 at
9:30 a.m., local time.


PURPOSE

     Nabors has stated that the purposes of the Special  Meeting are to consider
and vote upon the Nabors  Resolution  and to transact such other business as may
properly come before the Special  Meeting.  The Board  believes that under Texas
law and the Company's constituent corporate documents, only matters specifically
referred in the notice of a special  meeting (other than routine  administrative
matters) may be considered at the Special Meeting.


RECORD DATE; SHARES ENTITLED TO VOTE

     Only  holders of record of shares of Common  Stock at the close of business
on __________, 1998 (the "Record Date") are entitled to notice of and to vote at
the  Special  Meeting  and  at any  adjournment,  postponement  or  rescheduling
thereof.  On the  Record  Date,  there  were  _________  shares of Common  Stock
outstanding.  Such  shares of Common  Stock will each be  entitled  to one vote,
exercisable in person or represented by properly  executed  proxy, on any matter
properly before the Special Meeting.


                                       12

<PAGE>



QUORUM

     The  bylaws  of the  Company  require  the  holders  of a  majority  of the
outstanding  shares of Common  Stock to be present in person or  represented  by
properly executed proxy for any action to be taken at the Special Meeting, other
than an adjournment  thereof.  For purposes of  determining  whether this quorum
requirement is met, abstentions and broker non-votes received in connection with
properly signed and returned proxies will be counted as present.


REQUIRED VOTE

     While  broker-non  votes  (which are voted on at least one matter)  will be
counted as present at the Special Meeting for quorum  purposes,  such votes will
not be counted in determining the total number of shares entitled to vote on the
Nabors  Resolution at the Special Meeting,  assuming a quorum is present.  Under
such circumstances,  broker non-votes will have the practical effect of reducing
the number of  affirmative  votes that  Nabors  must  solicit in order to secure
majority approval of the Nabors  Resolution at the Special Meeting.  Abstentions
will be considered  present at the Special  Meeting for quorum purposes and will
be counted for purposes of  determining  the total number of shares  entitled to
vote on the  Nabors  Resolution.  Accordingly,  abstentions  will  have the same
effect as a vote against the Nabors  Resolution.  Your broker,  bank or nominee,
cannot vote your shares without receipt of your specific  instructions to do so.
Please contact the person  responsible  for your account and instruct him or her
to vote the GOLD proxy card on your behalf.


RECOMMENDATION OF THE BOARD

     WHETHER OR NOT YOU PLAN TO ATTEND THE SPECIAL MEETING,  SHAREHOLDERS SHOULD
READ AND CAREFULLY  CONSIDER THE  INFORMATION  PRESENTED IN THIS PROXY STATEMENT
AND ANY RELATED  MATERIAL SENT TO YOU BY THE BOARD AND VOTE "AGAINST" THE NABORS
RESOLUTION BY COMPLETING,  DATING AND SIGNING THE  ACCOMPANYING  GOLD PROXY CARD
AND  RETURNING  IT  PROMPTLY  TO  MACKENZIE  PARTNERS,   INC.  IN  THE  ENCLOSED
POSTAGE-PAID  ENVELOPE OR INSTRUCTING YOUR BROKER TO EXECUTE THE GOLD PROXY CARD
ON YOUR BEHALF.


REVOCABILITY OF PROXIES

     Unless you attend the Special Meeting and vote your shares in person,  only
your latest dated properly  executed proxy for the Special Meeting will count at
the Special  Meeting.  Any proxy given  pursuant to the  solicitation  by either
Nabors or the Board also may be revoked by (i) filing with the  Secretary of the
Company,  before the taking of the vote at the Special Meeting, a written notice
of revocation bearing a later date than the date of the proxy or any later-dated
proxy  relating to the same shares,  or (ii)  attending the Special  Meeting and
voting your shares in person.  Attendance at the Special Meeting will not in and
of itself  constitute a revocation of a proxy. THE BOARD URGES YOU TO REVOKE ANY
BLUE PROXY CARD THAT YOU HAVE DELIVERED TO NABORS OR ITS AGENTS.


OTHER INFORMATION REGARDING PROXIES

     All  shares  of Common  Stock  represented  by  properly  executed  proxies
received prior to or at the Special  Meeting,  and not duly and timely  revoked,
will be voted in accordance with the instructions  indicated on such proxies. If
no instructions are indicated on a properly  executed  returned GOLD proxy card,
such proxies will be voted AGAINST the Nabors  Resolution.  A properly  executed
proxy marked  "ABSTAIN,"  although  counted for purposes of determining  whether
there is a quorum for purposes of determining the aggregate voting power and the
number of shares represented at the Special Meeting, will not be voted.

     The Board  believes  that the  Nabors  Resolution  is the only  substantive
matter that may be acted upon at the Special Meeting. If, however, other matters
are properly brought before the Special Meeting, including among other things, a
motion to adjourn the meeting to another time and/or place  (including,  without
limitation,  for the  purpose of  soliciting  additional  proxies),  the persons
appointed as proxies will have  discretion  to vote or act thereon  according to
their judgment. If the Special Meeting is postponed or adjourned for any reason,
at any subsequent reconvening of the Special Meeting all proxies will be


                                       13

<PAGE>



voted on such matters in the same manner as such  proxies  would have been voted
at the original  convening of the Special  Meeting  (except for any proxies that
have theretofore  effectively been revoked or withdrawn),  notwithstanding  that
such proxies may have been effectively  voted in the same or any other manner at
a previous meeting.


DISSENTERS' RIGHTS

     Shareholders will not be entitled to dissenters' rights under the TBCA with
respect to the proposal to adopt the Nabors Resolution.

                             SOLICITATION OF PROXIES

     In  addition  to the  use of the  mail,  facsimile,  telephone,  telegraph,
advertisements  and in  person  communications,  arrangements  will be made with
banks,  brokerage  houses and other  custodians,  nominees  and  fiduciaries  to
forward  proxy  materials  to the  beneficial  owners of Common  Stock,  and the
Company will, upon request,  reimburse them for their reasonable expenses. Proxy
solicitations may be made by directors and officers of the Company, none of whom
will receive additional compensation for such solicitation.

     The Company has retained  MacKenzie  Partners,  Inc. for  solicitation  and
advisory  services in connection with this  solicitation  by the Board,  and has
recently  engaged Morgan Stanley as its financial  advisor to assist the Company
with the review and further  implementation  of the Company's growth  strategies
and to assist the Company in evaluating the unsolicited  acquisition proposal by
Nabors.

     The cost of  soliciting  proxies  on  behalf  of the  Board  for use at the
Special  Meeting is being borne by the Company.  The Company  estimates that the
total  expenditures in connection with the solicitation  (including the fees and
expenses of its attorneys,  public relations advisors,  investment advisors, and
proxy solicitors,  and advertising,  printing,  mailing, travel and other costs,
but  excluding   salaries  and  wages  of  officers  and   employees)   will  be
approximately  $ , of which  approximately $ has been spent to date. The Company
has also agreed to indemnify some of its advisors from certain liabilities.


                       CERTAIN FORWARD LOOKING INFORMATION

     Portions  of this  Proxy  Statement  include  statements  regarding  future
financial  performance  and results of operations and other  statements that are
not historical facts but are  forward-looking  statements  within the meaning of
Section 27A of the  Securities  Act of 1933, as amended,  and Section 21E of the
Securities Exchange Act of 1934, as amended ("Exchange Act").  Statements to the
effect that the  Company,  the Board or  management  "anticipates,"  "believes,"
"estimates,"  "expects," "predicts," or "projects" a particular result or course
of events,  or that such result or course of events "should" occur,  and similar
expressions,  are also  intended to identify  forward-looking  statements.  Such
statements  are  subject  to  numerous  risks,  uncertainties  and  assumptions,
including  but not limited to  uncertainties  relating  to  industry  and market
conditions,  prices of crude oil and natural gas,  foreign exchange and currency
fluctuations, political instability in foreign jurisdictions, the ability of the
Company to integrate  newly acquired  operations and other factors  discussed in
this Proxy  Statement  and in the Company's  other filings with the  Commission.
Should  one or more of  these  risks or  uncertainties  materialize,  or  should
underlying assumptions prove incorrect,  actual results may vary materially from
those stated.


                              SHAREHOLDER PROPOSALS

     Pursuant to Rule 14a-8 of the Rules and Regulations  promulgated  under the
Exchange Act,  shareholders  may present  proper  proposals for inclusion in the
Company's  Proxy Statement and for  consideration  at the next annual meeting of
its shareholders by submitting such proposals to the Company in a timely manner.
In order to be included for the 1999 annual meeting,  shareholder proposals must
have been  received  by the  Company no later than  December  1, 1998,  and must
otherwise  have complied with all  applicable  legal  requirements.  Shareholder
proposals  received after such time will be considered  untimely and will not be
considered  for  inclusion in the Company's  Proxy  Statement at the 1999 annual
meeting of shareholders.

COMPENSATION OF DIRECTORS

     Each  director  who  is  not  an  employee  of  the  Company  is  currently
compensated  by an annual cash  retainer  fee of $12,000 and an annual  grant of
1,000  shares of Common  Stock.  The  shares of Common  Stock may not be sold or
transferred  by the  director  for a period of one year  after the grant and are
subject to forfeiture if the director resigns as director prior to completion of
the one year period.  Such directors also receive a fee of $1,000 for each Board
or Board  committee  meeting  attended.  If more than one meeting is held on the
same day,  however,  full  payment is made for only one  meeting and the fee for
each  additional  meeting  attended that day is $800. In addition,  a $2,000 per
annum fee is paid for service on a Board  committee,  with an additional  $1,500
per annum paid to the chairman of a Board committee.  Directors who are employed
by the Company receive no additional  compensation for service as members of the
Board or any committee of the Board.

     Under the Company's 1996 Directors'  Stock Incentive Plan (the "1996 Plan")
each  director  who is not a full-time  employee  of the  Company  automatically
receives an initial grant of an option to purchase  8,000 shares of Common Stock
upon being  elected or appointed  to the Board for the first time (the  "Initial
Option  Grant") and receives an  additional  option to purchase  4,000 shares of
Common Stock on the date of each Annual Meeting of  Shareholders  after the year
in which the Initial  Option Grant  occurred (the "Annual  Option  Grant").  The
exercise  price of the  options is equal to the fair  market  value per share of
Common  Stock on the date an option is granted.  Each option  granted  under the
1996  Plan  becomes  exercisable  generally  one year from the date of grant and
expires ten years after the date of the grant. If a  participant's  service as a
director terminates by reason of disability,  death, the failure of the Board to
nominate him for reelection other than for "cause," as defined in the 1996 Plan,
or his  ineligibility for reelection  pursuant to the age limitation  imposed by
the Company's Bylaws,  his options may be exercised for up to one year after the
date of the disability, death or termination. If a director's service terminates
because he decides  not to stand for  reelection,  or if he becomes a  full-time
employee,  his options may be exercised for up to three months after such event,
and, if his service  terminates  for any other  reason,  except for "cause," his
options may be exercised for up to five business days after such

                                       A-2

<PAGE>



termination.  In the event a  director's  service  terminates  for  "cause"  his
options  will become  immediately  null and void.  Provision is made in the 1996
Plan for  adjustments  of options in cases of mergers,  stock splits and similar
capital  reorganizations  and for  immediate  vesting in the case of a change in
control of the Company.

     Directors  of the  Company  in office  prior to May 1996 also hold  options
previously  granted  pursuant to the 1991 Directors' Stock Option Plan which has
terms and conditions similar to the terms and conditions of the 1996 Plan.


INDEMNITY ARRANGEMENTS

     The Company's Bylaws obligate the Company to indemnify any person who is or
was a director,  officer, employee or agent of the Company to the fullest extent
that a  corporation  may or is required to grant  indemnification  to a director
under the TBCA. The Company's  Articles of  Incorporation,  as amended,  further
provide that a director of the Company shall not be liable to the Company or its
shareholders  for  monetary  damages for any act or omission in such  director's
capacity  as a  director  of the  Company,  in each case to the  fullest  extent
permitted by Texas law.

     On October  19,  1998,  the Board  approved a form of  indemnity  agreement
pursuant to which the Company will  contractually  agree to indemnify  directors
against  liabilities  arising from their serving as directors and to advance the
expenses  of  defending  against  such  liabilities.  This  agreement,  which is
designed to implement the indemnification provisions of Texas law to the maximum
practicable  extent,  sets forth,  among other things,  the standards of conduct
required  to receive  indemnification,  the  methods of  securing  approval  for
indemnity  payments  and the  procedural  requirements  necessary  to secure the
advancement of expenses.


COMPENSATION OF EXECUTIVE OFFICERS

     The Company's  executive  compensation is administered by the  Compensation
Committee of the Board.  The following  report  appeared in the Company's  Proxy
Statement dated April 2, 1998, for its 1998 annual meeting of shareholders:


                          COMPENSATION COMMITTEE REPORT
                                       ON
                             EXECUTIVE COMPENSATION

     This  report of the  Compensation  Committee  ("Committee")  sets forth the
Company's  policy with respect to executive  officer  compensation and describes
the  basis  for 1997  compensation  determinations  made by the  Committee  with
respect to the Chief  Executive  Officer  and other  executive  officers  of the
Company.


COMPENSATION PHILOSOPHY

     The Company's philosophy with regard to executive compensation is to:

     o    Provide a  competitive  total  compensation  package  consistent  with
          industry  practice  that enables the Company to attract and retain key
          executives.

     o    Structure  incentive  compensation so as to focus executive  attention
          and effort on the fulfillment of the Company's  financial  objectives,
          and on the appreciation of the value of the Company's stock.


COMPENSATION PROGRAM ELEMENTS

     The elements of the Company's  compensation  program for executive officers
are as follows:

     BASE  SALARY  --  Base  salary  levels  are  largely   determined   through
comparisons  with  compensation  paid to executives of companies of similar size
and  complexity as the Company  within the industry.  The Committee  attempts to
ensure that such pay levels are  competitive  within a range that the  Committee
considers  to be  reasonable  and  necessary.  The  Committee  utilizes for this
purpose surveys and the


                                       A-3

<PAGE>



assistance  of  outside  consultants  as well as market  information  from other
sources and takes into consideration the Company's  performance both in absolute
terms and in comparison  with other  companies in the industry.  With respect to
the  compensation  of  officers  other  than the Chief  Executive  Officer,  the
Committee  gives  strong  consideration  to the  recommendations  of  the  Chief
Executive  Officer which are based as to each such executive  officer largely on
performance, longevity and responsibilities.

     ANNUAL  INCENTIVE  COMPENSATION  -- The  Company's  executive  officers are
eligible to participate in management bonus plans established from time to time,
typically on an annual basis,  which provide for bonus awards based on attaining
or exceeding  specified  financial and other performance  objectives.  Under the
bonus  plan  that was in effect  for  1997,  bonus  awards  were  based on a net
earnings goal, an EBITD(1) goal and on return to shareholders in comparison with
a peer group of companies. For certain executives, a safety performance goal was
also added.  Provision was made for awards under such plan to be  increased,  in
the event performance goals were exceeded by specified amounts,  to a maximum of
twice the amount that would be awarded for  attaining  the targeted  performance
objectives. Actual awards were subject to decreases or increases on the basis of
the Committee's evaluation of the Company's and/or the executive's  performance,
although no such discretionary action was taken. The plan also provided that, at
the  Committee's  discretion,  up to 50 percent of any bonuses  payable for 1997
could be paid in Company  stock,  and the Committee  directed that 25 percent of
the 1997 bonuses would be paid in shares of restricted  stock  (restricted for a
period of one year of  continuing  service  after  receipt,  except for  earlier
retirement,  death,  disability or change in control). The amounts paid in stock
were, under the terms of the plan, increased by 15 percent.

     LONG TERM INCENTIVE COMPENSATION -- Executive officers also participated in
a long term  incentive  compensation  plan. In 1997,  award  opportunities  were
established for each executive  officer under which awards will be made based on
performance over a three-year period. The awards, if earned, will be paid solely
in restricted  stock (50 percent thereof  restricted for one year and 50 percent
restricted for two years of continuing service after receipt, except for earlier
retirement,  death,  disability  or change in control).  Entitlement  to receive
awards is based 50 percent on  cumulative  EBITD  performance  and 50 percent on
cumulative total return to shareholders  performance compared to a peer group of
companies over the three-year  period.  Target awards are set at a percentage of
each  recipient's  annual salary in effect at the  beginning of the  performance
period.  The target  awards will be  increased  by up to 50 percent in the event
performance goals are exceeded by specified amounts.

     STOCK  INCENTIVE PLAN -- The Company has an Employee  Stock  Incentive Plan
(the "Stock  Incentive  Plan")  pursuant to which  executive  officers and other
employees,  from time to time, may be granted  nonqualified  options to purchase
Company Common Stock. The exercise price of all such stock options is the market
price of the shares on the date the option is granted,  and the  realization  of
any value is, therefore,  totally dependent on future stock price  appreciation.
This is intended to provide added incentive to work for the continued growth and
success of the Company.  The Stock  Incentive Plan also permits the Committee to
make  awards  to  executive  officers  and  other  employees,  in  lieu  of cash
compensation,  of (i) Restricted  Stock (shares of Common Stock that are subject
to such  vesting  requirements  or other  restrictions  as the  Committee  shall
establish), and (ii) Bonus Stock (shares of Common Stock that are not subject to
vesting or other restrictions).

     SAR/PHANTOM  STOCK PLAN -- The Company has a plan (the  "SAR/Phantom  Stock
Plan") pursuant to which executive  officers and other  employees,  from time to
time, may be granted Stock  Appreciation  Rights and/or Phantom Stock awards.  A
Stock  Appreciation  Right is the right to receive,  upon the exercise  thereof,
cash in an amount equal to the excess of the fair market value of a share of the
Company's  Common Stock on the date of exercise over the base price of the Stock
Appreciation  Right. A Phantom Stock award  represents the right to receive cash
in an amount equal to the fair market value of a corresponding  number of shares
of Common Stock,  which vests over a period of time or upon the occurrence of an
event (including without limitation,  a change in control) as established by the
Committee,  without any payment to the Company by the participant (except to the
extent otherwise required by law). The SAR/Phantom Stock Plan is administered by
the Committee,  and the Committee  determines  eligibility and grants all awards
thereunder.

- ----------
(1)  EBITD is earnings before interest, income taxes,  depreciation/amortization
     and minority interest.


                                       A-4

<PAGE>



     The SAR/Phantom  Stock Plan was established  effective January 1, 1997, and
no  awards of Stock  Appreciation  Rights or  Phantom  Stock  have yet been made
thereunder.

     The Committee's overall objective in structuring incentive compensation for
executive  officers and other key personnel is to deliver  competitive levels of
compensation  for the  attainment  by the Company of  short-term  and  long-term
financial  objectives that the Committee  believes will favorably  influence the
Company's   stock  price  over  time.  The  Committee   further   believes  that
compensating  employees who have substantial  responsibility  for the management
and growth of the Company with Company  stock,  and providing  such persons with
opportunities  to benefit directly from increases in the value of Company stock,
will also align their  interests  more closely with those of other  shareholders
and  provide  additional  incentive  to  enhance  the  profitable  growth of the
Company.


1997 COMPENSATION

     The base salary level approved by the Committee in 1997 for Mr. Jongebloed,
as Chairman, President and Chief Executive Officer, was established on the basis
of (i) personal performance, (ii) Company performance, and (iii) comparison with
salaries for chief executive  officers of several  well-recognized  companies in
the same  industry as the  Company,  as reported by an outside  consultant,  Hay
Management Consultants ("Hay"). Such base salary level amounted to a 9.5 percent
increase over his previous base salary which had been in effect for the previous
12 months. Mr.  Jongebloed's bonus compensation for 1997 was calculated and paid
pursuant  to the  Company's  1997  Management  Bonus  Plan and was  based on the
Company's  attaining  or  exceeding  goals  based on (i) net income  compared to
budget,  (ii)  EBITD  performance   compared  to  budget  and  (iii)  return  to
shareholders compared to that of a peer group of companies. The bonus earned was
the maximum bonus attainable under the Plan.

     The  Committee  approved  base  salary  levels in 1997 for other  executive
officers  based on  recommendations  by the Chief  Executive  Officer  and Hay's
recommendations.  Bonuses for 1997 were paid to executive  officers  pursuant to
the  terms of the  Company's  1997  Management  Bonus  Plan and were  determined
totally  on the  Company's  financial  performance  for  the  year.  Each of the
executive  officers received a bonus on the basis of the Company's  attaining or
exceeding  the net  income,  EBITD and return to  shareholders  goals  mentioned
above.  These  bonuses were on average  approximately  96 percent of the maximum
bonuses attainable under the Plan.

     Stock option grants  pursuant to the Stock  Incentive Plan were made to Mr.
Jongebloed  and other  executive  officers in 1997,  as  reflected in the Option
Grants Table, on the basis of Hay's  recommendations,  each executive's personal
performance and the desire to link Company performance to compensation.


COMPLIANCE WITH INTERNAL REVENUE CODE SECTION 162(M)

     No formal policy has been adopted by the Company with respect to qualifying
compensation paid to its executive officers for an exemption from the limitation
on  deductibility  imposed by Section  162(m) of the Internal  Revenue Code. The
Company  anticipates that all compensation paid to its executive officers during
1997 will  qualify for  deductibility  because no  executive's  compensation  is
expected to exceed the dollar limitations of such provision.

(1)  Seventy-five  percent  of the  bonus  for  1997  was  paid in cash  and the
     remainder in  restricted  shares of Common  Stock,  the number of which was
     determined by dividing 25 percent of the bonus amount by the share price at
     the award  date and,  in  accordance  with  provisions  of the bonus  plan,
     increasing that result by 15 percent. The value at the award date of the 15
     percent  increase  is  included  in the  amount  shown  in the  "All  Other

     plan limits, to modify the terms of outstanding options.

(3)  The options have a term of ten years, but are subject to earlier expiration
     in certain events related to termination of employment.

(4)  The exercise price and any related tax withholding  obligations  arising in
     connection with exercise may be satisfied by the  optionholder's  surrender
     of  already-owned  shares or by offsetting a portion of the shares issuable
     upon exercise, subject to certain limitations.

(6)  Potential  shareholder  gain is included  for  comparison  purposes  and is
     calculated  assuming all outstanding shares were purchased at a price equal
     to the market price of the Common Stock  ($13.50 per share) on May 1, 1997,
     the date of the 1997 option grants.

</TABLE>

     Under  the  plan,  a  target  award  of  shares  was  established  for each
participant  based on a percentage of the  individual's  salary in effect at the
beginning of the applicable  three-year  performance  period. A payout under the
plan will depend on the extent to which the established performance criteria are
satisfied. Target awards are based 50 percent on earnings before interest, taxes
and  depreciation  performance and 50 percent on total return to shareholders as
compared  to a peer  group of  companies.  All  awards  are to be paid in Common
Stock,  to the extent  sufficient  shares are available under the Company's 1993
Employee  Stock  Incentive  Plan,  and otherwise are to be paid in cash.  Shares
received  under  the plan will be  restricted  so that,  (i) if the  executive's
employment  terminates within one year after the shares are earned,  100 percent
of the  shares  would  be  forfeited,  and  (ii) if the  executive's  employment
terminates  between one and two years  after the award is earned,  50 percent of
the  shares  would  be  forfeited  except  in the  event of  termination  of the
executive's employment due to retirement, death, total disability, redundancy or
change  in  control.  Target  payouts  are  equal to  specified  percentages  of
participants' annual base salaries in effect at the beginning of the performance
period, as follows: 60 percent for Mr. Jongebloed, 40 percent for Messrs. Myers,
Spillard and Hale, and 25 percent for Mr. Arms. Threshold payouts are one-fourth
of the  target  payouts,  and  maximum  payouts  are 150  percent  of the target
payouts.  Threshold payouts are made if performance falls within a certain range
below that which is necessary  to earn the target  award.  Maximum  payments are
made if  performance  exceeds by a specified  amount that which is  necessary to
earn the target payouts.


RETIRMENT BENEFITS AND CHANGE IN CONTROL ARRANGEMENTS

     RETIREMENT PLAN. The Company has a defined benefit  retirement plan for its
employees with different benefit formulas for salaried and hourly employees (the
"Qualified  Retirement  Plan"). The normal monthly retirement benefit payable at
age 65, or later if employment  continues beyond age 65, for salaried  employees
is equal to 1 percent of the monthly average of the  participant's  highest rate
of base  compensation  determined  as of each January 1 of any five  consecutive
years during the ten consecutive years preceding retirement, plus 0.6 percent of
the excess of  compensation  as so  determined  over the monthly  average of the
maximum taxable wage base used to calculate  old-age  benefits under the Federal
Social  Security  Act for the 35  years  ending  with  the  year  in  which  the
participant  will  attain his normal  retirement  age under the  Federal  Social
Security  Act,  multiplied by years and  fractions  thereof of credited  service
after May 1, 1990, up to 35 years.  The Qualified  Retirement  Plan provides for
actuarially  reduced benefits for early retirement.  Although the normal form of
benefit for married participants is a joint and 50 percent survivor annuity and,
for unmarried  participants,  a life only annuity, the Qualified Retirement Plan
permits other forms of benefit payment.  At December 31, 1997,  credited service
under the plan for Messrs.  Jongebloed,  Myers, Spillard, Hale and Arms was 7.67
years each, and the highest average annual  compensation  recognized by the plan
for each of them was  $152,000,  $152,000,  $152,000,  $152,000,  and  $132,800,
respectively.

- ----------
*    In accordance with the applicable  provisions of the Internal  Revenue Code
     of 1986, as amended,  annual  compensation above $160,000 is disregarded in
     calculating  benefits,   and  the  benefits  payable  under  the  Qualified
     Retirement Plan are limited to $125,000  annually.  Both limits are subject
     to adjustment  by the  Secretary of the Treasury to reflect  cost-of-living
     increases and are included in the above table.

     SUPPLEMENTARY  EXECUTIVE RETIREMENT PLANS. The Company has two nonqualified
supplementary  executive  retirement plans which provide retirement benefits for
certain senior  executives,  one of which plans was  implemented in 1993 and the
other in 1996. The 1993 plan provides benefits equal to 2 percent of the average
of the participant's  salary and annual bonus  compensation for each of the five
years for which such  compensation  was highest out of the last ten  consecutive
years of employment,  multiplied by years of credited service of employment with
the Company,  Pool Company and ENSERCH  Corporation,  up to 35 years,  minus (i)
social security benefits and (ii) retirement benefits payable to the participant
pursuant to, or resulting from his participation in, any other qualified defined
benefit plans of the Company, Pool Company or ENSERCH Corporation, including the
Qualified  Retirement  Plan.  The 1996  plan  provides  benefits  equal to 2 1/2
percent of the average of the participant's salary and annual bonus compensation
for each of the five years for which such  compensation  was  highest out of the
last  ten  consecutive  years of  employment,  multiplied  by years of  credited
service of employment with the Company, Pool Company and ENSERCH Corporation, up
to 24 years, minus (i) retirement  benefits payable to the participant  pursuant
to, or resulting from his  participation in, any other qualified defined benefit
plans of the  Company,  Pool  Company  or  ENSERCH  Corporation,  including  the
Qualified  Retirement Plan, and (ii) benefits payable pursuant to the 1993 plan.
The benefit  thus  determined  is payable in an  actuarial  equivalent  lump sum
amount.  Messrs.  Jongebloed,  Myers,  Spillard,  Hale and Arms are eligible for
benefits under such plans.  At December 31, 1997,  credited  service under these
plans for Messrs.  Jongebloed,  Myers,  Spillard,  Hale and Arms was 19.3,  9.9,
18.0,  26.1  and  22.2  years,  respectively,  and the  highest  average  annual
compensation  recognized by the plans for each of them was  $570,617,  $303,472,
$255,501, $246,852 and $179,449, respectively.

*    The annual  benefits  shown in the table have been reduced by the amount of
     any retirement benefits payable pursuant to other qualified defined benefit
     plans of the Company and other required offset items,  but does not reflect
     the offset which will be made for any benefits payable under any applicable
     ENSERCH Corporation retirement plan (see text above).

     POOL COMPANY  RETIREMENT PLAN.  Prior to the Company's  acquisition of Pool
Company,  Pool Company had a defined  benefit  retirement plan (which was merged
into the ENSERCH Corporation Retirement and Death Benefit Program) that provided
for  a  fixed  benefit  for  salaried  employees  upon  retirement  at  age  65.
Participants who were employees of the Company ceased to accrue further benefits
thereunder  on the  completion  of the  Company's  acquisition  of Pool Company.
Payments under this plan are offsets under the supplemental executive retirement
plans discussed above.  Pursuant to the terms of such plan, Messrs.  Jongebloed,
Myers,  and Spillard are entitled to annuity  payments of $19,635,  $3,299,  and
$12,226,  respectively,  per annum for life commencing upon normal retirement at
age 65. Messrs. Hale and Arms were not participants in such plan.

     CHANGE IN CONTROL AGREEMENTS. Messrs. Jongebloed, Myers, Spillard, Hale and
Arms each have entered into change in control  agreements  with the Company that
set forth  certain  benefits  that the Company  will  provide in the event their
employment is terminated  subsequent to a "change in control" of the Company, as
defined in the agreements.  Such  agreements  continue in effect for three years
following a change in control of the Company  unless  terminated  by the Company
prior to a change of control.  The agreements each provide that if the officer's
employment is terminated, or if the officer elects to terminate employment under
certain  circumstances  defined as "good reason," within three years following a
change in control of the  Company,  the  officer  will be entitled to a lump sum
severance payment equal to (i) three times the officer's annual base salary (but
not in  excess  of the  aggregate  base  salary  that  could be earned up to the
officer's  normal  retirement  date),  (ii) an amount equal to the largest bonus
paid to him during the preceding three years, prorated for the current year, and
(iii) the  value  over the  exercise  price of  unexercised  stock  options.  In
addition,  the officer will be entitled to a three-year  continuation of certain
employee  benefits,  two additional  years of service credit under the Company's
retirement program, and reimbursement of certain legal fees,  expenses,  and any
applicable excise taxes.
