Putnam, Hayes & Bartlett, Inc.
One Memorial Drive
Cambridge, Massachusetts 02142



                                                                   July 27, 1998



To the Stockholders of
Putnam, Hayes & Bartlett, Inc.:

     You are cordially  invited to attend a special  meeting of  stockholders of
Putnam,  Hayes & Bartlett,  Inc. ("PHB") to be held on August 27, 1998, at 10:00
a.m. at PHB's offices  located at 1776 I "Eye" Street,  N.W.,  Washington,  D.C.
20006.

     PHB  has  entered  into  an  Agreement  and  Plan of  Merger  (the  "Merger
Agreement")  with Hagler  Bailly,  Inc.  The Merger  Agreement  provides for the
combination  of Hagler Bailly and PHB in a merger of equals (the  "Merger").  At
the PHB special  meeting,  you will be asked to consider  and approve the Merger
Agreement and the Merger provided for therein.

     Under the Merger  Agreement,  each share of PHB common stock,  except those
shares of PHB  common  stock as to which  dissenters'  rights of  appraisal  are
properly  asserted,  will be  converted  into the  right to  receive a number of
shares of Hagler Bailly common stock equal to 6,600,000 divided by the number of
shares of PHB common  stock  issued  and  outstanding  immediately  prior to the
Merger's effective time  (approximately  1.2759 shares of Hagler Bailly for each
PHB  share  as of July 27,  1998),  plus  cash to be paid in lieu of  fractional
shares.  If  the  Merger  is  completed,   former  PHB  stockholders  will  have
approximately  40% of  the  outstanding  shares  of  Hagler  Bailly.  After  the
consummation  of the Merger,  a number of PHB directors and officers will assume
management and director  positions  with Hagler Bailly and/or its  subsidiaries.
You are urged to read the accompanying Joint Proxy  Statement/Private  Placement
Memorandum  which  describes  more  fully the  proposal  relating  to the Merger
Agreement and the Merger.

     The sale of the Hagler  Bailly  common  stock that current PHB common stock
holders will receive in connection with the Merger will not be registered  under
the  Securities Act of 1933 or applicable  securities  law.  Accordingly,  these
shares  of Hagler  Bailly  common  stock  will be  subject  to  restrictions  on
transferability  and resale.  If the Merger closes,  you may be required to bear
the  financial  risks of an  investment  in Hagler  Bailly  common  stock for an
indefinite period of time.

     After  careful  consideration,  PHB's Board of  Directors  has approved the
Merger  Agreement and the Merger  provided for therein and  recommends  that you
vote FOR the approval and adoption of the Merger  Agreement and the Merger.  The
Board of Directors of PHB believes the Merger offers PHB and its  stockholders a
number of important  benefits,  including  the  strategic  fit between PHB's and
Hagler Bailly's businesses,  long-term  administrative and operational economies
of scale,  and the opportunity to enjoy any  appreciation in the market price of
Hagler Bailly common stock which may occur in the future.

     All  stockholders  are  invited  to  attend  the  meeting  in  person.  The
affirmative  vote of holders of at least  two-thirds of the shares of PHB common
stock  outstanding as of the record date will be 


<PAGE>


necessary  under  Massachusetts  law for  approval  and  adoption  of the Merger
Agreement,  the Merger and the transactions  contemplated  therein. All of PHB's
directors, who beneficially own 4,392,500 shares, or 85%, of the outstanding PHB
common stock,  have agreed to vote their shares in favor of the Merger Agreement
and the Merger.

     However,  as  provided  in the Merger  Agreement,  the Merger will not take
place if the holders of more than 10% of the PHB common stock outstanding at the
closing demand appraisal rights as they are entitled under Massachusetts law.

     Whether  or not you  expect to attend  the PHB  special  meeting in person,
please  complete,  sign and  promptly  return  the  enclosed  proxy  card in the
enclosed  postage-prepaid envelope to assure representation of your shares. Your
prompt cooperation will be appreciated.


                                           Sincerely,


                                           Howard W. Pifer III
                                           Chairman


                                           William E. Dickenson
                                           President and Chief Executive Officer


YOUR PROXY IS  IMPORTANT.  PLEASE VOTE  PROMPTLY.  YOU SHOULD NOT  SURRENDER  OR
OTHERWISE  ATTEMPT TO EXCHANGE PHB STOCK  CERTIFICATES  FOR HAGLER  BAILLY STOCK
CERTIFICATES  UNLESS  AND  UNTIL  YOU  HAVE  RECEIVED   APPROPRIATE  NOTICE  AND
INSTRUCTIONS FOR EXCHANGE.

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

     NOTICE IS HEREBY GIVEN that a special  meeting of  stockholders  of Putnam,
Hayes & Bartlett, Inc. ("PHB") will be held on August 27, 1998, at 10:00 a.m. at
PHB's offices located at 1776 I "Eye" Street, N.W.,  Washington,  D.C. 20006 for

          Agreement"),  by and among PHB, Hagler Bailly,  Inc. ("Hagler Bailly")
          and a Hagler Bailly subsidiary.  Under the Merger Agreement,  PHB will
          become  a  wholly  owned  subsidiary  of  Hagler  Bailly  in a  merger
          transaction  (the "Merger") and each of the outstanding  shares of PHB
          common  stock,  par value $0.01 per share,  except  those shares as to
          which  dissenters'  rights of appraisal  have been asserted  properly,
          will be  converted  into the  right to  receive  a number of shares of
          Hagler  Bailly  common  stock,  par value  $0.01 per  share,  equal to
          6,600,000  divided by the number of shares of PHB common  stock issued
          and  outstanding  immediately  prior to the  Merger's  effective  time
          (approximately  1.2759  Hagler  Bailly shares for each PHB share as of
          July 27, 1998), plus cash to be paid in lieu of fractional shares; and

          2. To transact such other business as may properly come before the PHB
          special meeting, or any adjournments or postponements thereof.

     The Board of  Directors  of PHB has fixed the close of business on July 20,
1998 as the record date for the determination of stockholders of PHB entitled to
notice of and to vote at the PHB special meeting.  Only holders of record of PHB
common stock at the close of business on that date will be entitled to notice of
and to vote at the PHB  special  meeting or any  adjournments  or  postponements
thereof.  Under Massachusetts law, approval and adoption of the Merger Agreement
require  the  affirmative  vote of the  holders  of at least  two-thirds  of the
outstanding shares of PHB common stock. All of PHB's directors, who beneficially

their shares in favor of the Merger Agreement and the Merger.

     If the Merger and the Merger  Agreement  are approved by the holders of PHB
common stock at the special meeting and the Merger occurs, any stockholder:  (i)
who files with PHB,  before the taking of the vote on the approval of the Merger
and the Merger Agreement, written objection to the proposed actions stating that
such  stockholder  intends to demand payment for his or her shares if the Merger
is consummated and (ii) whose shares are not voted in favor of such action,  has
or may have the right to demand in writing from Putnam, Hayes & Bartlett,  Inc.,
which will survive the Merger as a wholly owned subsidiary of Hagler Bailly (the
"Surviving Corporation"),  within 20 days after the date written notice that the
Merger has become  effective  is mailed to such  stockholder,  payment  for such
stockholder's  shares  and an  appraisal  of the value  thereof.  The  Surviving
Corporation  and any such  stockholder  shall in such  cases have the rights and
duties  and  shall  follow  the  procedures  set  forth  in  Sections  88 to 98,
inclusive,  of Chapter  156B of the General  Laws of  Massachusetts.  The Merger
Agreement  provides  that the Merger  will not take place if the holders of more
than  10%  of  the  PHB  common  stock  demand  their  appraisal   rights  under
Massachusetts law.

     The Board of  Directors of PHB has  determined  that the Merger is fair to,
and in the best interests of, the  stockholders  of PHB, has approved the Merger
Agreement and the Merger,  and  recommends  that  stockholders  adopt the Merger
Agreement.

Hagler Bailly, Inc.
1530 Wilson Boulevard, Suite 400
Arlington, Virginia 22209

                                                                   July 27, 1998


To the Stockholders of
Hagler Bailly, Inc.:

     You are cordially  invited to attend a special  meeting of  stockholders of
Hagler  Bailly,  Inc. to be held on August 27, 1998, at 2:00 p.m. at 1530 Wilson
Boulevard, Suite 400, Arlington, Virginia 22209.

     Hagler Bailly has entered into an Agreement and Plan of Merger (the "Merger
Agreement") with Putnam,  Hayes & Bartlett,  Inc. ("PHB").  The Merger Agreement
provides for the combination of Hagler Bailly and PHB in a merger of equals (the
"Merger").  At the Hagler Bailly special meeting,  you will be asked to consider
and approve a proposal to authorize  the issuance of 6,600,000  shares of common
stock, par value $0.01 per share of Hagler Bailly,  to the holders of PHB common
stock,  par value  $0.01 per share,  in  connection  with the Merger (the "Share
Issuance").

     Under the Merger  Agreement,  each share of PHB common stock,  except those
shares of PHB  common  stock as to which  dissenters'  rights of  appraisal  are
properly  asserted  ("Dissenting  Shares"),  will be converted into the right to
receive a number of shares of Hagler  Bailly  common  stock  equal to  6,600,000
divided  by the  number of shares of PHB common  stock  issued  and  outstanding
immediately prior to the Merger's  effective time  (approximately  1.2759 Hagler
Bailly shares for each PHB share as of July 27,  1998),  plus cash to be paid in
lieu of fractional  shares. If the Merger is completed,  former PHB stockholders
will have  approximately  40% of the  outstanding  shares of Hagler Bailly.  The
shares  of  Hagler  Bailly  common  stock  held by  Hagler  Bailly  stockholders
immediately  prior to the Merger will remain unchanged by the Merger.  After the
consummation  of the Merger,  a number of PHB directors and officers will assume
management and director  positions  with Hagler Bailly and/or its  subsidiaries.
The accompanying Joint Proxy  Statement/Private  Placement  Memorandum describes
more fully the proposal relating to the Merger.

     After  careful  consideration,  Hagler  Bailly's  Board  of  Directors  has
approved  unanimously  the Merger  Agreement and the Merger provided for therein
and  recommends  that you vote FOR the Share  Issuance  in  connection  with the
Merger.  The Board of Directors  of Hagler  Bailly  believes  the Merger  offers
Hagler Bailly and its stockholders a number of important benefits, including the
strategic  fit  between  Hagler  Bailly's  and PHB's  businesses  and  long-term
administrative and operational economies of scale.

     Donaldson,  Lufkin & Jenrette, Inc. ("DLJ") has delivered an opinion to the
Board of  Directors of Hagler  Bailly that the  consideration  Hagler  Bailly is
paying in the  Merger is fair,  from a  financial  point of view,  to the Hagler
Bailly  stockholders.  DLJ's opinion describes the matters it considered and the
scope of its review  undertaken  in  rendering  the opinion.  DLJ's  opinion and
presentations  to the Hagler  Bailly  directors,  together  with a review by the
Hagler Bailly  directors of the assumptions  used by DLJ, were among the factors
the Hagler Bailly Board of Directors considered in reaching its 


<PAGE>


determination  to approve the Merger Agreement and the Merger. A copy of the DLJ
opinion is attached to the accompanying proxy statement as Annex B.

     At the Hagler Bailly  special  meeting,  you will also be asked to consider
and in separate  votes  approve:  (i) a proposed  amendment  to Hagler  Bailly's
Certificate  of  Incorporation  to increase the  authorized  number of shares of
Hagler  Bailly  common stock from  20,000,000  to  50,000,000  shares and (ii) a
proposed   amendment  to  the  Hagler  Bailly,   Inc.  Employee   Incentive  and
Non-Qualified  Stock Option and Restricted  Stock Plan to increase the number of
shares authorized to be issued under the plan from 3,200,000 to 5,000,000. After
careful  consideration,  Hagler Bailly's Board of Directors has approved both of
these amendments and recommends that you vote FOR their approval.  The Merger is
not conditioned upon the approval of either of these amendments.

     All stockholders  are invited to attend the meeting in person.  Approval of
the Share  Issuance  and the  amendment  to the  option  plan each  require  the
affirmative  vote of the  majority of the total votes cast  regarding  each such
proposal. Approval of the amendment to the Certificate of Incorporation requires
the affirmative  vote of a majority of the  outstanding  shares of Hagler Bailly
common  stock.  Stockholders  are  urged to  review  carefully  the  information
contained in the accompanying proxy statement.

     The  directors  and certain  officers of Hagler  Bailly have agreed to vote
their  respective  shares of Hagler  Bailly  common  stock in favor of the Share
Issuance. These Hagler Bailly stockholders  beneficially owned, as of the Hagler
Bailly record date, an aggregate of 2,624,824 shares,  or approximately  27%, of
the outstanding Hagler Bailly common stock entitled to vote at the Hagler Bailly
special  meeting.  It is expected that each of these Hagler Bailly  stockholders
will also vote his shares of Hagler  Bailly  common  stock for  approval  of the
respective amendments to the Certificate of Incorporation and the stock plan.

     Whether or not you expect to attend the Hagler  Bailly  special  meeting in
person, please complete, sign and promptly return the enclosed proxy card in the
enclosed  postage-prepaid  envelope to assure representation of your shares. You
may revoke your proxy at any time  before it has been  voted,  and if you attend
the  meeting you may vote in person even if you have  previously  returned  your
proxy card. Your prompt cooperation will be greatly appreciated.



                                                Sincerely,

                                                /s/ Henri-Claude Bailly

                                       of
                               HAGLER BAILLY, INC.

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

     This Joint  Proxy  Statement/Private  Placement  Memorandum  ("Joint  Proxy
Statement/PPM")  is being  furnished  to  stockholders  of Hagler  Bailly,  Inc.
("Hagler  Bailly").   It  relates  to  the  special  meeting  of  Hagler  Bailly
stockholders  to be  held on  August  27,  1998,  at 2:00  p.m.  at 1530  Wilson
Boulevard,  Suite 400,  Arlington,  Virginia 22209,  and to any  adjournments or
postponements   of  the  Hagler  Bailly  special   meeting.   This  Joint  Proxy
Statement/PPM  is first being mailed to Hagler Bailly  stockholders  on or about
July 27, 1998.

     In  addition,   this  Joint  Proxy  Statement/PPM  is  being  furnished  to
stockholders  of  Putnam,  Hayes &  Bartlett,  Inc.  ("PHB").  It relates to the
special meeting of PHB stockholders to be held on August 27, 1998, at 10:00 a.m.
at PHB's offices located at 1776 I "Eye" Street, N.W.,  Washington,  D.C. 20006,
and to any adjournments or postponements of the PHB special meeting.  This Joint
Proxy  Statement/PPM  also serves as a private  placement  memorandum  regarding
shares of Hagler Bailly common stock,  par value $0.01,  to be issued as part of
the Merger (as defined below) and is first being mailed to PHB  stockholders  on
or about July 27, 1998.

     At the PHB special  meeting,  the principal item of business will be a vote
on the  Agreement  and Plan of Merger,  dated as of June 11,  1998 (the  "Merger
Agreement"),  by and between Hagler Bailly, PHB and a wholly owned subsidiary of
Hagler  Bailly  ("Merger  Sub")  under  which  PHB will  become  a wholly  owned
subsidiary  of Hagler  Bailly in a merger  transaction  (the  "Merger").  At the
Hagler Bailly special meeting,  the Hagler Bailly  stockholders will be asked to
approve,  in separate  votes,  the issuance of up to 6,600,000  shares of Hagler
Bailly common stock in  connection  with the Merger (the "Share  Issuance"),  an
amendment to Hagler Bailly's  Certificate of  Incorporation  that would increase
the maximum  number of  authorized  shares of Hagler  Bailly  common  stock from
20,000,000 to 50,000,000 shares (the  "Certificate  Amendment") and an amendment
to the Hagler Bailly, Inc. Employee Incentive and Non-Qualified Stock Option and
Restricted  Stock Plan to increase the number of shares  authorized to be issued
under the plan from 3,200,000 to 5,000,000 (the "Stock Option Plan  Amendment").
Neither the  approval of the  Certificate  Amendment  nor the Stock  Option Plan
Amendment is a condition to the Merger.

     The Merger  Agreement  provides for a merger of equals of Hagler Bailly and
PHB whereby  Merger Sub will be merged with and into PHB, with PHB continuing as
the surviving corporation and as a wholly owned subsidiary of Hagler Bailly (the
"Surviving  Corporation").  As part of the Merger,  each issued and  outstanding
share of PHB common stock par value $0.01 per share,  except  treasury stock and
those  shares of PHB common  stock as to which  dissenters'  rights of appraisal
have been properly asserted  ("Dissenting  Shares"),  will be converted into the
right to  receive a number of shares of Hagler  Bailly  common  stock,  equal to
6,600,000  divided  by the  number of  shares of PHB  common  stock  issued  and
outstanding immediately prior to the Effective Time (as defined below). Based on
the  5,172,500  outstanding  shares  of PHB  common  stock  on  July  27,  1998,
approximately  1.2759  shares of Hagler  Bailly  common stock would be issued in
exchange for each share of PHB common stock  outstanding in connection  with the
Merger,  excluding treasury stock (the "Exchange  Ratio").  Cash will be paid in
lieu of fractional  shares.  The Merger Agreement  provides that any outstanding
stock  option to  purchase  PHB  common  stock  will be  terminated  before  the
Effective  Time,  and that  Hagler  Bailly will  withhold  and deposit in escrow
150,000 shares of Hagler Bailly common stock issued to PHB  stockholders  in the
Merger  to cover the tax  


<PAGE>

indemnification  obligations of the PHB stockholders  under the Merger Agreement
(the "Escrow Shares").

     The  Merger is subject to various  conditions,  including  approval  of the
Merger and the  Merger  Agreement  by PHB  stockholders,  approval  of the Share
Issuance  by  Hagler  Bailly  stockholders  and that  the  aggregate  number  of
Dissenting Shares be no more than 10% of the PHB common stock outstanding at the
closing.  The directors and certain officers of Hagler Bailly,  who beneficially
owned, as of the Hagler Bailly record date, an aggregate of 2,624,824 shares, or
approximately  27%, of the  outstanding  Hagler Bailly common stock  entitled to
vote at the Hagler Bailly special meeting,  have agreed to vote their respective
shares of Hagler  Bailly  common  stock in favor of the  Share  Issuance.  It is
expected that each of these Hagler Bailly stockholders will also vote his shares
of Hagler Bailly common stock for approval of the Certificate  Amendment and the
Stock Option Plan  Amendment.  Also, all of PHB's directors who owned, as of the
PHB record date, an aggregate of 4,392,500 shares, or approximately  85%, of the
outstanding PHB common stock entitled to vote at the PHB special  meeting,  have
agreed  to vote  their  respective  shares of PHB  common  stock in favor of the
Merger  Agreement  and the Merger  provided for therein.  Hagler  Bailly and PHB
expect that the Merger will be  consummated  immediately  after all  stockholder
approvals are obtained.  If the Merger is not  consummated  by October 31, 1998,
either party, subject to certain exceptions, may terminate the Merger Agreement.
For a more detailed description of the Merger and the Merger Agreement, see "THE
MERGER."

     This Joint Proxy  Statement/PPM  also relates to the private offer and sale
of the up to 6,600,000 shares of Hagler Bailly common stock which will be issued
in  connection  with the Merger.  The shares of Hagler  Bailly  common stock are
offered pursuant to an exemption from  registration  under the Securities Act of
1933, as amended (the "Securities  Act"), and certain state securities acts, and
rules and  regulations  promulgated  thereunder.  The Hagler Bailly common stock
issued in connection with the Merger may not be transferred in the absence of an
effective  registration  statement under the Securities Act and applicable state
securities laws or exemptions therefrom.  However, if the Merger is consummated,
PHB stockholders will receive certain  registration and "tag along" rights.  See
"THE MERGER -- The Registration Rights Agreement."

     The  information  set forth in this Joint  Proxy  Statement/PPM  concerning
Hagler  Bailly  and  Merger  Sub  has  been  furnished  by  Hagler  Bailly.  The
information  concerning PHB has been furnished by PHB. The  descriptions  of the
Merger Agreement,  the Escrow Agreement,  the Registration  Rights Agreement and
the Affiliate Agreements (as defined below) are summaries which are qualified in
their  entirety  by  reference  to  the  text  of  those  documents,  which  are
incorporated  herein by reference and attached to this Joint Proxy Statement/PPM
as Annex A.

Bailly common stock to any PHB  stockholder  in any  jurisdiction  in which such
offering may not be made lawfully.

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

         Neither  the  delivery  of this Joint  Proxy  Statement/PPM  to the PHB
stockholders or the Hagler Bailly  stockholders  nor any  distribution of Hagler
Bailly common stock to the PHB  stockholders  pursuant to the Merger shall imply
that  there  has been no change in the  information  set forth  herein or in the
affairs of Hagler Bailly or PHB since the date hereof.

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

common stock, should be reviewed by each PHB stockholder, his or her investment,

                                     SUMMARY

     The following is a brief summary of certain information contained elsewhere
in this Joint Proxy Statement/PPM. This summary is not intended to be a complete
description  and is qualified in its entirety by reference to the more  detailed
information contained elsewhere in this Joint Proxy Statement/PPM.  Stockholders
of Hagler Bailly and PHB are urged before  voting to give careful  consideration
to all of the  information  contained in or  incorporated by reference into this
Joint Proxy Statement/PPM.

The Hagler Bailly Special Meeting

     The Hagler Bailly  special  meeting will be held on August 27, 1998 at 2:00
p.m. at 1530 Wilson Boulevard,  Suite 400,  Arlington,  Virginia 22209, at which
time Hagler Bailly stockholders of record at the close of business on the Hagler
Bailly  record date  (described  below) will be asked to consider and vote upon:
(i) a proposal  to approve  the Share  Issuance;  (ii) a proposal to approve and
adopt the Certificate Amendment; (iii) a proposal to approve and adopt the Stock
Option Plan  Amendment  and (iv) such other  matters as may be brought  properly
before the Hagler  Bailly  special  meeting.  Approval of the Share  Issuance by
Hagler Bailly  stockholders is a condition to the Merger,  while approval of the
Certificate  Amendment and approval of the Stock Option Plan  Amendment are not.
Approval of the Share  Issuance and approval of the Stock Option Plan  Amendment
each  requires  the  affirmative  vote of the  majority  of the total votes cast
regarding  the  respective  proposals.  Approval  of the  Certificate  Amendment
requires the affirmative vote of a majority of the issued and outstanding shares
of Hagler Bailly common stock.

     The  directors  and certain  officers of Hagler  Bailly have agreed to vote
their  respective  shares of Hagler  Bailly  common  stock in favor of the Share
Issuance.  See "THE  MERGER -- The  Support  Agreements."  These  Hagler  Bailly
stockholders  beneficially  owned,  as of the  Hagler  Bailly  record  date,  an
aggregate of 2,624,824 shares, or approximately  27%, of the outstanding  Hagler
Bailly common stock entitled to vote at the Hagler Bailly special meeting. It is
expected that each of these Hagler Bailly stockholders will also vote his shares
of Hagler  Bailly  common stock for approval of the  Certificate  Amendment  and
approval of the Stock Option Plan Amendment.

The PHB Special Meeting

     The PHB  special  meeting  will be held on August 27, 1998 at 10:00 a.m. at
PHB's offices located at 1776 I "Eye" Street,  N.W.,  Washington,  D.C. 20006 at
which time PHB stockholders of record at the close of business on the PHB record
date  (described  below) will be asked to consider and vote upon: (i) a proposal
to approve and adopt the Merger  Agreement  and the Merger  provided for therein
and (ii) such other  matters as may be brought  properly  before the PHB special
meeting or any  adjournments or postponements  thereof.  The affirmative vote of
the holders of  two-thirds  of the issued and  outstanding  shares of PHB common
stock   entitled  to  vote  at  the  PHB  special   meeting  is  required  under
Massachusetts  law to  approve  and adopt the  Merger  Agreement  and the Merger
provided  for  therein.  It is a  condition  to the  Merger,  however,  that the
aggregate  number of  Dissenting  Shares  be no more than 10% of the PHB  common
stock outstanding at the closing.

         The directors of PHB have agreed to vote their respective shares of PHB
common  stock in favor of the  Merger  Agreement  and the  Merger  provided  for
therein.  These PHB stockholders  owned, as of the PHB record date, an aggregate
of 4,392,500 shares,  or approximately  85%, of the outstanding PHB common stock
entitled  to vote at the PHB  special  meeting.  See "THE  MERGER -- The Support
Agreements."

     Merger  Sub.  Merger  Sub is a wholly  owned  subsidiary  of Hagler  Bailly
created to facilitate the Merger. Merger Sub has no operations.

     Structure

     The Merger  Agreement  provides for a merger of equals to be facilitated by
the  merger  of  Merger  Sub  with  and  into  PHB,  with  PHB as the  Surviving
Corporation.  If the Merger is completed,  the Surviving  Corporation  will be a
wholly owned  subsidiary of Hagler Bailly and will continue to do business under
the name Putnam, Hayes & Bartlett, Inc.

     At the Effective Time (as defined below), each issued and outstanding share
of PHB common stock,  except for treasury stock and any Dissenting Shares,  will
be  converted  into the right to  receive  a number  of shares of Hagler  Bailly
common stock,  equal to 6,600,000  divided by the number of shares of PHB common
stock issued and outstanding  immediately  prior to the Effective Time. Based on
the  5,172,500  outstanding  shares  of PHB  common  stock  on  July  27,  1998,
approximately  1.2759  shares of Hagler  Bailly  common stock would be issued in
exchange for each share of PHB common stock in connection with the Merger.  Cash
will be paid in lieu of fractional  shares.  The Merger Agreement  provides that
all outstanding  stock options to purchase PHB common stock ("PHB Options") will
be terminated  before the Effective Time. All shares of PHB common stock held as
treasury stock will be canceled.  The Merger Agreement also provides that at the
Effective Time,  Hagler Bailly will withhold and deposit in escrow for up to one
year,  the  Escrow  Shares  to  indemnify  Hagler  Bailly  and  certain  persons
affiliated with Hagler Bailly as to certain taxation matters. See "THE MERGER --
The Escrow  Agreement."  Upon and after the consummation of the Merger, a number
of PHB directors and officers will assume management and director positions with
Hagler Bailly and/or its subsidiaries.  See "THE MERGER - Post-Merger Management
of Hagler  Bailly and the Surviving  Corporation"  and "THE MERGER - Post-Merger
Board of Directors of Hagler Bailly."

     The  Merger  will  result in an  expansion  of Hagler  Bailly's  consulting
business and is consistent with Hagler Bailly's overall growth strategy.  Hagler
Bailly and PHB will strengthen



                                      -2-
<PAGE>


considerably each other's consulting  capabilities and expand  substantially the
combined  company's  presence in the  corporate  sector in the United States and
abroad.  Together,  the parties will be the largest publicly held management and
economic  consulting  firm  specializing in energy,  network  industries and the
environment  with  combined  revenues  of  nearly  $159  million  in 1997  and a
worldwide staff of more than 700.

     Recommendation of the Hagler Bailly Board of Directors

     The Board of  Directors  of Hagler  Bailly  believes  that the terms of the
Merger  Agreement  and the  Merger are fair to,  and in the best  interests  of,
Hagler Bailly and its stockholders.  The Board of Directors of Hagler Bailly has
unanimously  approved the Merger  Agreement and the Merger and  recommends  that
holders of Hagler Bailly common stock vote "FOR" approval of the Share Issuance.
For a discussion of the factors considered by the Board of Directors in reaching
its  decision,  see "The Merger --  Background  of the Merger" and "THE MERGER--
Recommendation  of the Hagler  Bailly  Board of  Directors  and  Reasons for the
Merger."

     Opinion of Hagler Bailly's Financial Advisor

     On June 8, 1998,  Donaldson,  Lufkin & Jenrette,  Inc. ("DLJ") delivered an
opinion to the Board of Directors of Hagler Bailly that the consideration Hagler
Bailly is paying in the Merger is fair,  from a financial  point of view, to the
Hagler Bailly  stockholders.  DLJ's opinion  describes the matters it considered
and the scope of its review  undertaken in rendering the opinion.  DLJ's opinion
and presentations to the Hagler Bailly directors,  together with a review by the
Hagler Bailly  directors of the assumptions  used by DLJ, were among the factors
the Hagler Bailly Board of Directors considered in reaching its determination to
approve  the Merger  Agreement  and the  Merger.  See "The  Merger -- Opinion of
Hagler Bailly's Financial Advisor." A copy of DLJ's opinion letter dated June 8,
1998,  is attached as Annex B to this Joint  Proxy  Statement/PPM  and should be
read by Hagler Bailly stockholders in its entirety.

     Recommendation of the PHB Board of Directors

     The  Board  of  Directors  of PHB  believes  that the  terms of the  Merger
Agreement are fair to, and in the best  interests of, PHB and its  stockholders.
The Board of Directors of PHB approved the Merger  Agreement  and the Merger and
recommends  that holders of PHB common stock vote "FOR" approval and adoption of
the Merger Agreement and the Merger.  For a discussion of the factors considered
by the  Board  of  Directors  in  reaching  its  decision,  see "The  Merger  --
Background of the Merger" and "THE MERGER --  Recommendation of the PHB Board of
Directors and Reasons for the Merger."

     Effective Time and Conditions to Closing

     The Merger will become effective when the articles of merger are filed with
the Secretary of State of the Commonwealth of Massachusetts and the Secretary of
State of the State of Delaware in accordance with applicable law (the "Effective
Time").  The articles of merger will be filed as promptly as possible  after the
parties receive all reasonable assurances or opinions, as applicable,  as to the
tax  and  accounting  treatment  of the  Merger,  certain  documents,  opinions,
consents and certificates are received,  certain agreements are entered into and
Hagler Bailly stockholders have approved the Share Issuance and PHB stockholders
have approved the Merger Agreement and the Merger, provided the aggregate number
of  Dissenting  Shares is 10% or less of the  outstanding  shares of PHB  common
stock.  PHB and Hagler Bailly expect that the Merger will be consummated as soon
as possible after all stockholder approvals are obtained,  but in no event later
than October 31, 1998.

     Exchange of PHB Common Stock Certificates

     Upon the  Effective  Time,  each holder of a certificate  representing  PHB
common stock issued and outstanding  immediately  prior to the Merger will, upon
the surrender thereof to Hagler Bailly's transfer agent (the "Exchange  Agent"),
be entitled to receive a certificate  representing the number of whole shares of
Hagler  Bailly  common  stock into  which  such PHB common  stock will have been


                                      -3-
<PAGE>


automatically  converted as part of the Merger (less a certificate  representing
such holder's pro rata portion of the Escrow  Shares).  The Exchange  Agent will
mail a letter of transmittal  with  instructions to all holders of record of PHB
common stock immediately after the Effective Time for use in surrendering  their
certificates of PHB common stock in exchange for new  certificates  representing
Hagler Bailly common stock and cash in lieu of fractional  shares.  Certificates
should not be  surrendered by PHB  stockholders  until the letter of transmittal
and instructions  are received.  See "The Merger -- Exchange of PHB Common Stock
Certificates."

     Termination

     The Merger  Agreement  may be terminated at any time prior to the Effective
Time by the  mutual  consent  of PHB and  Hagler  Bailly  and by  either of them
individually under certain specified  circumstances,  including by either PHB or
Hagler Bailly if: (a) the other party breaches certain of the Merger Agreement's
terms and does not cure such breach within a specified  time; (b) closing of the
Merger  is  prevented  or  prohibited  by law;  (c) the  Effective  Time has not
occurred on or prior to October 31, 1998 or (d) the Share Issuance or the Merger
Agreement and the Merger are not approved by Hagler Bailly or PHB  stockholders,
respectively.  Also,  either  PHB or Hagler  Bailly  may  terminate  the  Merger
Agreement if it provides  proper notice to the other after  receiving a Superior
Proposal  (as  defined  below).  If one of the  parties  terminates  the  Merger
Agreement  after  receiving a Superior  Proposal or under certain  circumstances
involving a Competing  Transaction (as defined  below),  the other party will be
entitled  to a  termination  fee  equal  to $10  million.  See  "The  Merger  --
Termination and Amendment of the Merger Agreement."

     Affiliate Agreements

     Each of PHB's  and  Hagler  Bailly's  affiliates  have or will  enter  into
agreements not to dispose of or encumber their shares for a period of time after
the Effective Time. See "The Merger -- The Affiliate Agreement."

     Employment Agreements

     Certain  members  of the  Board  of  Directors  of PHB  have  entered  into
employment  agreements with Hagler Bailly which will become  effective after the
Effective Time (the "Employment  Agreements").  See "THE MERGER - The Employment
Agreements."

     Registration Rights Agreement

     Hagler Bailly and PHB  stockholders  who will receive  Hagler Bailly common
stock pursuant to the Merger will execute an agreement (the "Registration Rights
Agreement") which will give them, among other things,  certain  registration and
other  rights with  respect to the Hagler  Bailly  common  stock they receive in
connection  with  the  Merger.  See  "THE  MERGER  -  The  Registration   Rights
Agreement."

     Post-Merger Management and Board of Directors

     As part of the Merger  Agreement  certain PHB and Hagler  Bailly  personnel
will assume certain management positions with Hagler Bailly and/or the Surviving
Corporation.  The Merger  Agreement  also  provides for the elections of two new
members to the Hagler Bailly Board of Directors.  See "THE MERGER -- Post-Merger
Management  of Hagler Bailly and the  Surviving  Corporation"  and "THE MERGER -
Post-Merger Board of Directors of Hagler Bailly."

     Tax Treatment

     It is intended  that the Merger will  qualify as a tax free  reorganization
within the  meaning of Section  368 of the  Internal  Revenue  Code of 1986,  as
amended (the "Code"),  and that the Merger Agreement shall constitute a "plan of
reorganization"  for the purposes of the Code. See "THE MERGER -- Federal Income
Tax Consequences."



                                      -4-
<PAGE>


     Accounting Treatment

     The Merger is intended to qualify as a pooling-of-interests  for accounting
and financial reporting purposes. One of the closing conditions to the Merger is
that Hagler  Bailly and PHB shall have received a letter from Ernst & Young LLP,
independent public accountants to both parties, in form and substance reasonably
satisfactory  to Hagler  Bailly  and PHB,  to the effect  that the  transactions
contemplated  by the Merger  Agreement  will  qualify  for  pooling-of-interests
accounting  treatment.  Hagler Bailly and PHB anticipate  that Ernst & Young LLP
will deliver letters  indicating,  among other things, its concurrence in Hagler
Bailly's  management's  conclusions that no conditions exist that would preclude
Hagler Bailly from accounting for the Merger as a pooling-of-interests. See "The
Merger -- Accounting Treatment."

     Dissenters' Appraisal Rights

     Under  the   Massachusetts   Business   Corporation   Law   ("Massachusetts
Corporation  Law") in connection with the Merger,  PHB stockholders are entitled
to appraisal rights for the value of their shares of PHB common stock,  provided
they follow  certain  procedures.  The failure of a  dissenting  stockholder  to
follow these  procedures may result in the  termination or waiver of dissenters'
rights.  See "THE MERGER --  Dissenters'  Appraisal  Rights." The Hagler  Bailly
stockholders do not have any dissenters'  rights of appraisal in connection with
the Merger.

     Interests of Certain Persons in the Merger

     Certain PHB personnel have entered into  employment  agreements with Hagler
Bailly which will become  binding after the  Effective  Time.  These  employment
agreements  provide these  persons with  contractual  rights to employment  with
Hagler  Bailly or its  subsidiaries  for  certain  specified  periods  after the
Effective Time.  Also,  certain PHB and Hagler Bailly officers and/or  directors
will become directors  and/or  officers,  or be nominated to become directors in
the  future,  of  Hagler  Bailly  or its  subsidiaries.  See "THE  MERGER -- The
Employment  Agreements"  and "The Merger -- Interests of Certain  Persons in the
Merger."

     Description  of Hagler Bailly  Capital Stock and  Comparison of Stockholder
     Rights

     If the Merger is  consummated,  PHB  stockholders  will  become  holders of
Hagler Bailly common stock. There are certain  differences between the rights of
Hagler Bailly  stockholders and PHB  stockholders  that stem from differences in
the  organizational  documents,  bylaws  and the laws of  respective  states  of
incorporation  of Hagler Bailly and PHB. For instance,  unlike PHB, the Board of
Directors of Hagler Bailly has three classes with staggered  terms. In addition,
the Hagler Bailly  Certificate  of  Incorporation  authorizes  issuance of up to
5,000,000  shares of preferred  stock. For a description of the capital stock of
Hagler  Bailly  and a  summary  of these and other  differences  in  stockholder
rights,  see  "DESCRIPTION  OF HAGLER  BAILLY  CAPITAL  STOCK AND  COMPARISON OF
STOCKHOLDER RIGHTS."

     Market Prices of Common Stock

     Hagler Bailly common stock is traded on the Nasdaq Stock Market. The symbol
for Hagler  Bailly  common  stock is "HBIX."  PHB common  stock is not  publicly
traded.

     Risk Factors

     Because the market price of Hagler  Bailly  common stock may  fluctuate and
the number of shares of Hagler Bailly common stock to be issued in the Merger is
fixed,  the market  value of the shares of Hagler  Bailly  common stock that PHB
stockholders  will  receive in the Merger may  increase or  decrease  materially
prior to the Effective Time. No assurance can be given as to the market price of
Hagler  Bailly  common  stock at the time of the  Merger.  Also,  there  will be
limitations  on the  transferability  of shares of Hagler  Bailly  common  stock
received by PHB  stockholders in the Merger.  PHB  stockholders  should consider
these and other  factors  concerning  the  business of Hagler  Bailly and Hagler
Bailly  common  stock  in  determining  how to vote  on the  Merger.  See  "RISK
FACTORS."

The Certificate Amendment

     Hagler Bailly  stockholders are also being asked to approve the Certificate
Amendment, which would increase the authorized number of shares of Hagler Bailly
common stock from  20,000,000  to  50,000,000.  The Board of Directors of Hagler
Bailly  believes  that the  Certificate  Amendment  is in the best  interests of
Hagler Bailly and its stockholders.  The Board of Directors of Hagler Bailly has
approved the Certificate  Amendment and recommends that holders of Hagler Bailly
common stock vote "FOR" its approval. See "The CERTIFICATE AMENDMENT."

The Stock Option Plan Amendment

     Hagler Bailly Stockholders are also being asked to approve the Stock Option
Plan  Amendment,  which would  increase  the number of shares  authorized  to be
issued under the Hagler Bailly,  Inc. Employee Incentive and Non-Qualified Stock
Option and  Restricted  Stock Plan (the "Stock Option  Plan") from  3,200,000 to
5,000,000.  The Board of  Directors  of Hagler  Bailly  believes  that the Stock
Option  Plan  Amendment  is in the  best  interests  of  Hagler  Bailly  and its
stockholders.  The Board of  Directors  of Hagler  Bailly has approved the Stock
Option Plan Amendment and recommends  that holders of Hagler Bailly common stock
vote "FOR" its approval. See "THE STOCK OPTION PLAN AMENDMENT."

                       THE HAGLER BAILLY SPECIAL MEETING

General

     This Joint  Proxy  Statement/PPM  is first  being  mailed to Hagler  Bailly
stockholders  on or about  July 27,  1998 and is  accompanied  by the  Notice of
Special Meeting and a form of proxy that is solicited by the Hagler Bailly Board
of Directors for use at the Hagler Bailly  special  meeting to be held on August
27,  1998,  at 2:00 p.m.,  local  time,  at 1530  Wilson  Boulevard,  Suite 400,
Arlington, Virginia 22209.

Matters to be Considered

     At the Hagler Bailly special meeting,  Hagler Bailly  stockholders  will be
asked in separate  votes,  to consider and approve:  (i) in accordance  with the
requirements of the Nasdaq Stock Market, the Share Issuance;  (ii) in accordance
with the requirements of Delaware General Corporation Law ("Delaware Corporation
Law"),  the  Certificate  Amendment  and (iii) the Stock Option Plan  Amendment.
Approval of the Share Issuance by Hagler Bailly  stockholders  is a condition to
the Merger,  while approvals of the  Certificate  Amendment and the Stock Option
Plan Amendment are not.

Record Date and Voting

     The Board of  Directors  has fixed  July 15,  1998 as the  record  date for
determination of holders of Hagler Bailly common stock entitled to notice of and
to vote at the Hagler  Bailly  special  meeting.  Accordingly,  only  holders of
record  at the  close of  business  on the  Hagler  Bailly  record  date will be
entitled  to notice of and to vote at the Hagler  Bailly  special  meeting.  The
number of shares of Hagler  Bailly  common stock  entitled to vote at the Hagler
Bailly special meeting is 9,627,503,  held by 111  stockholders of record.  Each
share of Hagler Bailly  common stock  entitles its holder to one vote. No shares
of Hagler Bailly preferred stock are issued and outstanding.

     If the  enclosed  proxy card is executed  properly  and  received by Hagler
Bailly  in time to be voted  at the  special  meeting,  the  shares  represented
thereby  will be  voted in  accordance  with the  instructions  marked  thereon.
Executed proxies with no instructions  indicated thereon will be voted "FOR" the
Share Issuance, the Certificate Amendment and the Stock Option Plan Amendment.

     The Board of Directors of Hagler  Bailly is not aware of any matters  other
than the Share  Issuance,  the  Certificate  Amendment and the Stock Option Plan
Amendment that may be brought properly before the Hagler Bailly special meeting.
If any other matters properly come before the Hagler Bailly special meeting, the
persons named in the accompanying  proxy will vote the shares represented by all
properly  executed proxies on such matters in such manner as shall be determined
by a majority of the Board of Directors of Hagler Bailly.

Vote Required; Revocability of Proxies

     The  presence,  in person or by proxy,  of the holders of a majority of the
shares of Hagler Bailly common stock issued and  outstanding  and entitled to be
voted at the Hagler Bailly special  meeting is necessary to constitute a quorum.
Abstentions  and broker  non-votes  will be included in the  calculation  of the
number of shares  represented at the Hagler Bailly special  meeting for purposes
of  determining  whether  a quorum  has been  achieved.  Approval  of the  Share
Issuance and the Stock Option Plan Amendment each requires the affirmative  vote
of a majority of all shares of Hagler Bailly common stock represented, in person
or by proxy,  and voting at the meeting and the presence of a quorum of at least
a majority of the issued and  outstanding  shares of Hagler Bailly common stock.
Abstentions  and broker  non-votes  will not count as votes for or  against  the
Share Issuance or the Stock Option Plan  Amendment.  Approval of the Certificate
Amendment requires the affirmative 



                                      -7-
<PAGE>


vote of the holders of at least a majority of the issued and outstanding  shares
of Hagler Bailly common stock  entitled to be voted at the Hagler Bailly special
meeting.  Abstentions  and broker  non-votes  will have the same effect as votes
against the Certificate Amendment.

     The  directors  and certain  officers of Hagler  Bailly have agreed to vote
their  respective  shares of Hagler  Bailly  common  stock in favor of the Share
Issuance. These Hagler Bailly stockholders  beneficially owned, as of the Hagler
Bailly record date, an aggregate of 2,624,824 shares,  or approximately  27%, of
Hagler  Bailly  common  stock  entitled  to vote at the  Hagler  Bailly  special
meeting. See "THE MERGER -- The Support Agreements." It is expected that each of
these Hagler  Bailly  stockholders  will vote his shares of Hagler Bailly common
stock for approval of both the  Certificate  Amendment and the Stock Option Plan
Amendment.

     The  accompanying  form of proxy is for use at the  meeting  if a holder of
Hagler  Bailly  common  stock is unable to attend in person.  The  presence of a
stockholder at the Hagler Bailly special meeting will not  automatically  revoke
such stockholder's proxy.  However, a stockholder may revoke a proxy at any time
prior to its exercise by (a) delivering to Daniel M. Rouse, Corporate Secretary,
Hagler Bailly,  Inc.,  1530 Wilson  Boulevard,  Suite 400,  Arlington,  Virginia
22209,  a written  notice of revocation  prior to the special  meeting or a duly
executed  proxy bearing a later date or (b) attending the Hagler Bailly  special
meeting and voting in person.  All shares  represented by valid proxies received
pursuant to this solicitation,  and not revoked before they are exercised,  will
be voted in the manner specified therein.

Solicitation of Proxies

     In addition to solicitation by mail,  directors,  officers and employees of
Hagler  Bailly may solicit  proxies for the Hagler Bailly  special  meeting from
Hagler  Bailly  stockholders  personally  or by  telephone  or telegram  without
additional remuneration therefor.  Hagler Bailly will pay the cost of soliciting
proxies.   In  addition,   Hagler   Bailly  has  retained   Corporate   Investor
Communications, Inc., a proxy solicitation firm, to assist in such solicitation.
The fee to be paid by  Hagler  Bailly to such firm is  $5,000,  plus  reasonable
out-of-pocket expenses. Hagler Bailly will also make arrangements with brokerage
firms and other custodians,  nominees and fiduciaries to send proxy materials to
their principals and will reimburse such parties for their expenses in doing so.

                             THE PHB SPECIAL MEETING

Matters to be Considered

     This Joint Proxy Statement/PPM is first being mailed to PHB stockholders on
or about  July  27,  1998,  and is  accompanied  by a proxy  card  furnished  in
connection  with the  solicitation  of proxies by the PHB Board of Directors for
use at the PHB special meeting.  The PHB special meeting is scheduled to be held
on August 27,  1998,  at 10:00 a.m.,  at PHB's  offices  located at 1776 I "Eye"
Street,  N.W.,  Washington,  D.C.  20006.  At the PHB special  meeting,  the PHB
stockholders  will consider and vote upon: (i) the proposal to approve and adopt
the Merger  Agreement  and the Merger  provided  for therein and (ii) such other
business  as  may  come  properly  before  the  PHB  special  meeting,   or  any
adjournments or postponements thereof including, without limitation, a motion to
adjourn the PHB special  meeting to another time and/or place for the purpose of
soliciting  additional  proxies in order to approve the Merger Agreement and the
Merger or otherwise.

Record Date and Voting

     The record date for determining the holders of PHB common stock entitled to
receive  notice  of and to vote at the PHB  special  meeting  is July 20,  1998.
Accordingly, only holders of record of PHB common stock at the close of business
on the PHB record date will be entitled to vote at the PHB special meeting or at
any  adjournment or  postponement  thereof.  At the close of business on the PHB
record date,  there were 5,172,500  shares of PHB common stock  outstanding  and
entitled  to  vote  at  the  PHB  special  meeting,  held  by  approximately  76
stockholders  of record.  Each holder of PHB common stock on the PHB record date
will be  entitled  to one vote for each  share held of record  upon each  matter
properly  submitted  at  the  PHB  special  meeting  or at  any  adjournment  or
postponement  thereof.  No  shares  of  preferred  stock of PHB are  issued  and
outstanding.

     If the enclosed proxy card is properly executed and received by PHB in time
to be voted at the PHB special meeting,  the shares represented  thereby will be
voted in accordance with the instructions marked thereon.  Executed proxies with
no  instructions  indicated  thereon will be voted "FOR" the proposal to approve
and adopt the Merger Agreement and the Merger provided for therein.

     The Board of  Directors  of PHB is not aware of any matters  other than the
proposal to approve and adopt the Merger Agreement and the Merger (or a proposal
to adjourn or postpone the PHB special meeting as necessary) that may be brought
properly  before the PHB special  meeting.  If any other  matters  properly come
before the PHB special meeting, the persons named in the accompanying proxy will
vote the shares  represented by all properly executed proxies on such matters in
such manner as shall be  determined  by a majority of the Board of  Directors of
PHB.

     PHB stockholders  should not forward any PHB common stock certificates with
their proxy cards. If the merger is consummated,  stock  certificates  should be
delivered in accordance with  instructions  set forth in a letter of transmittal
which would be sent to PHB stockholders by the Exchange Agent promptly after the
effective time.

Vote Required; Revocability of Proxies

     The affirmative  vote of at least  two-thirds of the issued and outstanding
shares of PHB common  stock  entitled to be voted at the PHB special  meeting is
required  in order to  approve  and adopt the  Merger  Agreement  and the Merger
provided for therein. Abstentions will have the same effect as votes against the
Merger  Agreement.  The Merger is  conditioned  upon,  among other  things,  the
aggregate  number of Dissenting  Shares being no more than 10% of the PHB common
stock outstanding at the closing.

     All of the directors of PHB, who  beneficially  owned, as of the PHB record
date, an aggregate of 4,392,500 shares, or approximately 85%, of the outstanding
shares of PHB common stock,  have 



                                      -9-
<PAGE>

agreed,  among other  things,  to vote all their  shares of PHB common  stock in
favor  of  the  Merger  Agreement,   the  Merger  and  the  other   transactions
contemplated  by  the  Merger   Agreement.   See  "THE  MERGER  --  The  Support
Agreements."

     The accompanying form of proxy is for use at the meeting if a holder of PHB
common stock is unable to attend in person. The presence of a stockholder at the
PHB Special  Meeting will not  automatically  revoke such  stockholder's  proxy.
However,  a stockholder  may revoke a proxy at any time prior to its exercise by
(a) delivering to Barbara Levine,  Clerk,  Putnam,  Hayes & Bartlett,  Inc., One
Memorial Drive,  Cambridge,  Massachusetts 02142, a written notice of revocation
prior to the special  meeting or a duly  executed  proxy bearing a later date or
(b)  attending  the PHB  special  meeting  and  voting  in  person.  All  shares
represented by valid proxies  received  pursuant to this  solicitation,  and not
revoked  before  they  are  exercised,  will be voted  in the  manner  specified
therein.

Solicitation of Proxies

     In addition to solicitation by mail,  directors,  officers and employees of
PHB may solicit proxies for the PHB special meeting from stockholders personally
or by telephone or telegram without additional  remuneration  therefor. PHB will
pay the cost of soliciting proxies.

                                  RISK FACTORS

     This Joint Proxy  Statement/PPM  contains  forward-looking  statements that
involve risks and  uncertainties.  Actual results could differ  materially  from
those  anticipated  in these  forward-looking  statements as a result of certain
factors  including,  but not limited to, those set forth in the  following  risk
factors.

Fixed Number of Hagler Bailly Shares

     Because the number of shares of Hagler  Bailly common stock to be issued in
the Merger is fixed,  the market value of the Hagler  Bailly  common stock to be
received  by  holders of PHB  common  stock in the Merger may change  materially
between  the date of this  Joint  Proxy  Statement/PPM  and the  closing  of the
Merger.

Challenge of Successful Integration of Two Businesses

     There  can be no  assurance  that  Hagler  Bailly  and PHB  will be able to
profitably manage or successfully integrate their businesses without substantial
expenses, delays or other operational or financial problems. Further, the Merger
and integration of the two companies may divert management's attention, increase
costs to improve managerial,  operational, financial and administrative systems,
cause  unanticipated  events  or  circumstances,   legal  liabilities,  increase
interest expense and amortization of acquired  intangible assets, some or all of
which  could  have a  materially  adverse  impact on Hagler  Bailly's  business,
operating results and financial condition. To the extent that the integration of
the businesses  results in reduced  performance  under ongoing  contracts,  such
performance  problems and any  associated  client  dissatisfaction  could have a
materially  adverse impact on the reputation of the combined company as a whole.
In addition,  there can be no assurance  that the combined  company will achieve
anticipated  revenues  and  earnings.  The  failure of Hagler  Bailly and PHB to
manage the Merger  successfully  could have a material  adverse effect on Hagler
Bailly's business, operating results and financial condition.

Restrictions on Transfer of Merger Consideration

     If the Merger is  consummated,  the sale of the Hagler  Bailly common stock
that PHB  stockholders  will receive in  connection  with the Merger will not be
registered under the Securities Act or otherwise.  Accordingly,  these shares of
Hagler Bailly common stock may not be transferred or resold, except as permitted
under the Securities  Act and  applicable  state  securities  laws,  pursuant to
registration or exemption therefrom.  If the Merger closes, PHB stockholders may
be required to bear the financial risks of an investment in Hagler Bailly common
stock for an indefinite period of time.

Client Conflicts

     The  parties  have  identified  certain  conflicts  of  interest  in  their
respective environmental practices. If the Merger is consummated,  Hagler Bailly
will exit segments of the U.S. public sector  environmental  consulting business
that conflict with the  assignments of the combined  company.  This will require
Hagler Bailly to terminate Natural  Resources Damage  Assessment  consulting and
expert testimony for U.S. Federal and State governmental agencies. This business
accounted for  approximately  $5 million in revenues in 1997.  After the Merger,
the parties plan to create a committee to eliminate any other  conflicts.  Other
conflicts of interest  between the parties'  businesses  may currently  exist or
exist in the future, although the parties have not identified any such conflicts
at this time.

Attraction, Retention and Management of Professional and Administrative Staff

     Both  Hagler  Bailly's  and  PHB's  businesses   involve  the  delivery  of
professional  services and are labor  intensive.  The combined  company's future
performance depends in large part upon its ability to attract, develop, motivate
and retain highly skilled  consultants,  research  associates and 



                                      -11-
<PAGE>

administrative   staff,   particularly   senior   professionals   with  business
development  skills.  Qualified  consultants  are in great demand,  and there is
significant  competition  for employees with these skills from other  consulting
and investment  banking firms,  research firms,  energy companies and many other
related  enterprises.  Many of these firms have substantially  greater financial
resources  than  Hagler  Bailly  and  PHB,  which  they may use to  attract  and
compensate  qualified  personnel.  There can be no  assurance  that the combined
company will be able to attract and retain sufficient  numbers of highly skilled
consultants in the future.  The loss of the services of a significant  number of
consultants,  research  associates  or  administrative  personnel  could  have a
material adverse effect on the combined  company's  business,  operating results
and  financial   condition,   including  its  ability  to  secure  and  complete
engagements.

Concentration of Revenues

     Substantially all of the revenues of Hagler Bailly are derived from private
and   institutional   clients   involved  in  the  energy,   telecommunications,
transportation  and environmental  industries.  A substantial  majority of PHB's
revenues is derived  from  clients in the energy and  network and  environmental
industries.  As a result  of this  focus,  each of  Hagler  Bailly's  and  PHB's
business,  financial  condition  and results of  operations  are,  and after the
Merger should continue to be,  influenced by factors affecting these industries,
including changing political, economic and regulatory influences that may affect
the  procurement  practices  and  operation  of  energy,  network  industry  and
environmental service providers. In particular,  many electric and gas utilities
are consolidating to create larger organizations or strategic  alliances.  These
consolidations  and alliances will reduce the number of potential  customers for
the combined  company and may also create conflicts of interest between clients.
In addition, these consolidations and alliances may result in the acquisition of
certain of Hagler  Bailly's  and PHB's key  clients,  and such clients may scale
back or terminate  their  relationship  with Hagler  Bailly and/or PHB following
their  acquisition.  Similarly,  cutbacks  in  the  energy,  telecommunications,
transportation  and/or  environmental  budgets  of the  United  States and other
governments  could  result in the scale  back or  termination  of some of Hagler
Bailly's public sector  contracts.  The impact of such developments is difficult
to predict and could have a material  adverse  effect on the combined  company's
business, financial condition and results of operations.

Ability to Sustain and Manage Growth

     Hagler Bailly has experienced  rapid growth in recent years,  including two
acquisitions  and an initial public offering  ("IPO") of its securities.  Hagler
Bailly believes that its continued growth places a strain on operational,  human
and  financial  resources.  In order to manage its  growth,  Hagler  Bailly must
continue to improve its operating and administrative  systems and to attract and
retain qualified management and professional, scientific and technical operating
personnel.   Foreign  operations  also  may  involve  the  additional  risks  of
assimilating  differences in foreign  business  practices,  hiring and retaining
qualified personnel, and overcoming language barriers.  Failure to manage growth
effectively  could  have a material  adverse  effect on the  combined  company's
business, financial condition and results of operations.

Dependence on Key Clients

     Hagler  Bailly  derives,  and after the  Merger  is likely to  continue  to
derive, a significant  portion of its revenues from a relatively  limited number
of clients.  For  example,  revenues  from Hagler  Bailly's 10 most  significant
clients  accounted for 51.7%,  61.0%,  and 50.1% of its total  revenues in 1995,
1996 and 1997, respectively. A U.S. government agency, USAID, is Hagler Bailly's
largest client,  accounting for 27.5%, 34.9%, and 33.0% of Hagler Bailly's total
revenues in 1995, 1996 and 1997,  respectively.  In 1996 and 1997, revenues from
PHB's largest 10 clients  represented  38.0% and 37.0% of PHB's total  revenues,
respectively.  Clients  typically  retain  Hagler Bailly and PHB as needed on an
engagement basis rather than pursuant to long-term  contracts,  and a client can
usually  terminate  an  engagement  at any time without a  significant  penalty.
Moreover,  there can be no  assurance  that Hagler  Bailly's  or PHB's  existing
clients will continue to use the combined company



                                      -12-
<PAGE>


for additional  assignments or do so at the same revenue levels. The loss of any
significant  client  could  have a  material  adverse  effect  on  the  combined
company's business,  results of operations and financial condition. In addition,
the  level  of  the  combined  company's  consulting  services  required  by  an
individual  client  can  diminish  over  the life of its  relationship  with the
combined  company,  and there can be no assurance that the combined company will
be successful in establishing relationships with new clients as this occurs.

Professional and Other Liability

     Both Hagler Bailly's and PHB's services  involve risks of professional  and
other liability.  If either company were found to have been negligent or to have
breached  its  obligations  to its clients,  it could be exposed to  significant
liabilities and its reputation could be adversely  affected.  In connection with
many of its public sector  engagements,  Hagler  Bailly  employs the services of
local  staff  and  consultants  who  are  treated  as  independent  contractors.
Negligent  or  illegal  acts,  or  ethical   violations  by  these   independent
contractors could adversely affect the combined company. Hagler Bailly maintains
professional  liability insurance to an aggregate maximum of $10.0 million.  PHB
does not maintain any professional liability insurance.

Partnering Arrangements

     Historically, Hagler Bailly's and PHB's revenues have been generated either
on a standard hourly or daily rate basis or a cost plus fixed-fee basis.  Hagler
Bailly anticipates an increasing portion of its management  consulting  services
will be billed pursuant to alternative pricing  arrangements,  which may include
incentive and  success-based  fees. In addition,  Hagler Bailly is pursuing,  in
certain  select  instances,  opportunities  to invest its own  capital and other
resources  in  partnering  arrangements  involving  early  stage  energy-related
technologies and projects in the energy, telecommunications,  transportation and
environmental  industries.  Hagler Bailly has limited prior experience investing
its  own  funds  in  external  ventures.  Such  compensation   arrangements  and
investments  may result in  significant  time delays  between the  incurrence of
costs in  delivering  services  and the  receipt of the related fee or return on
invested capital, as the case may be.

Public Sector Market and Contracting Risks

     Revenues  from  contracts  or  subcontracts   with  public  sector  clients
accounted  for 47.7% and 52.8% of Hagler  Bailly's  total  revenues  in 1996 and
1997, respectively.  Providing consulting services to public sector customers is
subject to detailed  regulatory  requirements  and public policies as well as to
funding  priorities.  Contracts with public sector  customers may be conditioned
upon the  continuing  availability  of public funds,  which in turn depends upon
lengthy and complex budgetary procedures,  and may be subject to certain pricing
constraints. Moreover, public sector contracts may generally be terminated for a
variety of factors, including when it is in the best interests of the respective
government.  There can be no assurance  that these  factors or others  unique to
contracts with governmental  entities will not have a material adverse effect on
the combined company's business, results of operations and financial condition.

Intense Competition

     The market  for  consulting  services  in the  energy,  telecommunications,
transportation  and environmental  industries is intensely  competitive,  highly
fragmented  and  subject  to rapid  change,  and such  competition  is likely to
increase in the  future.  Many of Hagler  Bailly's  and PHB's  competitors  have
greater  personnel,  financial,  technical and marketing  resources  than Hagler
Bailly or PHB. Hagler Bailly also competes with its clients' internal resources,
particularly  where such  resources  represent a fixed cost to the client.  This
source of competition may heighten as  consolidation of electric and gas utility
and other energy industry companies creates larger  organizations.  There can be
no assurance that the combined company will be able to compete successfully with
its existing competitors or with any new competitors.



                                      -13-
<PAGE>


Risk of International Operations

     Hagler Bailly operates either permanent or project offices in a total of 27
foreign countries. PHB operates offices in two foreign countries.  Hagler Bailly
expects  to  continue  to  expand  its  international  operations  and  offices.
Expansion  into new  geographic  regions  requires  considerable  management and
financial  resources and may negatively impact Hagler Bailly's near-term results
of operations. Hagler Bailly's and PHB's international operations are subject to
numerous  potential  challenges and risks,  including  war, civil  disturbances,
other political and economic conditions in various jurisdictions such as tariffs
and  other  trade  barriers,   longer  accounts  receivable  collection  cycles,
fluctuations in currency and potentially adverse tax consequences.  There can be
no assurance that such  international  factors will not have a material  adverse
effect on the combined company's  business,  results of operations and financial
condition.

Dependence on Key Employees

     The success of Hagler Bailly and PHB are highly dependent upon the efforts,
abilities,  business  generation  capabilities  and  project  execution  of  its
officers and those of its subsidiaries. The loss of the services of any of these
individuals  for any  reason,  could have a  material  adverse  effect  upon the
combined  company's  business,   operating  results  and  financial   condition,
including its ability to secure and complete engagements.

Concentration of Ownership

     After giving  effect to the Merger,  the  directors  and officers of Hagler
Bailly (including officers of subsidiaries) beneficially will own 10,504,780, or
approximately  65%, of Hagler Bailly's  outstanding shares of common stock. As a
result,  these stockholders will have substantial  influence over the outcome of
matters requiring a stockholder  vote,  including the election of the members of
the Board of Directors.  Such control could adversely affect the market price of
Hagler  Bailly's  common stock or delay or prevent a change of control of Hagler
Bailly at a price,  which might represent a premium over the market price of its
common stock.

Need to Develop New Offerings

     The combined  company's  future success will depend in significant  part on
its ability to develop  and  introduce  successful  new  service  offerings  and
improved versions of existing service offerings.  There can be no assurance that
the combined  company will be successful in developing,  introducing on a timely
basis and marketing such service  offerings,  or that any service offerings will
be accepted in the market.  Moreover,  services offered by others may render the
combined company's services non-competitive or obsolete.

Project Risks

     Many of Hagler Bailly's and PHB's  engagements  involve  projects which are
critical to the  operations  of their  customers'  businesses  and which provide
benefits that may be difficult to quantify.  The combined  company's  failure or
inability to meet a customer's  expectations  in the performance of its services
could result in the incurrence of a financial loss and could damage the combined
company's  reputation and adversely  affect its ability to attract new business.
In addition,  an unanticipated  difficulty in completing a project could have an
adverse  effect on the combined  company's  business and results of  operations.
Fees for  Hagler  Bailly's  and  PHB's  engagements  typically  are based on the
project schedule,  staffing requirements,  the level of customer involvement and
the scope of the  project  as agreed  upon with the  customer  at the  project's
inception. Hagler Bailly and PHB generally seek to obtain adjustments in fees in
the event of any  significant  change in any of the  assumptions  upon which the
original  estimate was based.  However,  there can be no  assurance  that Hagler
Bailly or PHB will be successful in obtaining any such adjustment in the future.



                                      -14-

<PAGE>


Intellectual Property Rights

     Both  Hagler  Bailly's  and PHB's  performance  is in part  dependent  upon
internal  information  and  communication  systems,  databases,  tools,  and the
methods and procedures  that have been developed  specifically to serve clients.
Hagler  Bailly and PHB each rely on a  combination  of  nondisclosure  and other
contractual  arrangements  and  copyright,  trademark  and trade  secret laws to
protect its proprietary  systems,  information  and procedures.  There can be no
assurance  that  the  steps  taken  by  Hagler  Bailly  or  PHB to  protect  its
proprietary rights will be adequate to prevent  misappropriation  of such rights
or that Hagler  Bailly or PHB will be able to detect  unauthorized  use and take
appropriate steps to enforce its proprietary rights.  Hagler Bailly and PHB each
believe that their systems and  procedures and other  proprietary  rights do not
infringe upon the rights of third parties.  There can be no assurance,  however,
that third parties will not assert  infringement claims against Hagler Bailly or
PHB in the future or that any such claims will not require  Hagler Bailly or PHB
to enter into costly litigation or materially adverse settlements to litigation,
regardless of the merits of such claims.

Government Regulation of Immigration

     Certain of Hagler Bailly's  employees are foreign  nationals working in the
United  States under U.S.  visas or work  permits.  Congress and  administrative
agencies with jurisdiction over immigration matters have periodically  expressed
concerns over the levels of legal and illegal  immigration  into the U.S.  These
concerns  have often  resulted in proposed  legislation,  rules and  regulations
aimed at reducing the number of work permits that may be issued.  Any changes in
such laws making it more  difficult  to hire  foreign  nationals or limiting the
ability of Hagler Bailly to retain foreign employees could require Hagler Bailly
to incur additional unexpected labor costs and expenses.

Fluctuations of Operating Results

     Hagler  Bailly's  future  operating  results will continue to be subject to
quarterly  fluctuations  based upon a wide  variety of  factors,  including  the
number and significance of client  engagements  commenced and completed during a
quarter,  delays  incurred  in  connection  with an  engagement,  the  number of
business days in a quarter,  employee hiring and utilization  rates, the ability
of clients to terminate  engagements  without  penalties,  the size and scope of
engagements,  the nature of the fee arrangement, the seasonality of the spending
cycle  of  public  sector  clients   (especially   that  of  the  United  States
government),  the timing of new office openings,  return on investment  capital,
and the general economy,  such as recessionary periods,  political  instability,
changes in trade policies,  fluctuations in interest or currency  exchange rates
and  other  competitive  factors.   Seasonality  also  affects  Hagler  Bailly's
operating  results,  particularly  in the third  quarter of each fiscal year. In
addition,  Hagler  Bailly's  operating  expenses are increasing as Hagler Bailly
continues  to expand  its  operations,  and  future  operating  results  will be
adversely affected if revenues do not increase accordingly. Additionally, Hagler
Bailly plans to continue to evaluate and, when appropriate, make acquisitions of
complementary businesses. As part of this process Hagler Bailly will continue to
evaluate the changing value of its assets, and when necessary,  make adjustments
thereto.  While Hagler Bailly cannot  predict what effect these various  factors
may have on its  financial  results,  the  aggregate  effect  of these and other
factors  could  result  in  significant  volatility  in Hagler  Bailly's  future
performance and stock price.

Fluctuations in the General Economy

     The general level of economic  activity  significantly  affects  demand for
Hagler Bailly's and PHB's professional  services.  When economic activity slows,
clients may delay or cancel plans that involve the hiring of consultants. Hagler
Bailly and PHB are both unable to predict the level of economic  activity at any
particular  time, and fluctuations in the general economy could adversely affect
the combined company's business, operating results and financial condition.


                                      -15-
<PAGE>


Employment Liability Risks

     Hagler Bailly and PHB, as providers of  professional  services,  employ and
place individuals in the workplace of other  businesses.  Inherent risks of such
activity  include  possible  claims of errors  and  omissions,  misuse of client
proprietary   information,   misappropriation   of  funds,   discrimination  and
harassment, theft of client property, other criminal activity or torts and other
claims.  Although historically neither Hagler Bailly nor PHB has experienced any
material  claims of these  types,  there can be no  assurance  that the combined
company will not experience such claims in the future.

Certain Anti-takeover Effects

     Hagler  Bailly's  Certificate  of  Incorporation,   By-laws,  and  Delaware
Corporation  Law  include  provisions  that may be deemed to have  anti-takeover
effects and may delay,  defer or prevent a takeover  attempt  that  stockholders
might consider in their best interests. These include a Board of Directors which
is divided  into  three  classes,  each of which is  elected to serve  staggered
three-year  terms,  and by-law  provisions  under  which only the  President,  a
majority of the Board of Directors or stockholders owning at least 50% of Hagler
Bailly's capital stock may call meetings of the stockholders. Also, the Board of
Directors of Hagler  Bailly is  authorized  to issue up to  5,000,000  shares of
preferred stock and to determine the price,  rights,  preferences and privileges
of such shares,  without any further  stockholder  action. The existence of this
"blank-check"  preferred  stock could  render more  difficult or  discourage  an
attempt to obtain  control of Hagler Bailly by means of a tender offer,  merger,
proxy  contest  or  otherwise.  Furthermore,  Hagler  Bailly is  subject  to the
anti-takeover  provisions  of  Section  203 of  Delaware  Corporation  Law  that
prohibits  Hagler  Bailly  from  engaging in a  "business  combination"  with an
"interested  stockholder"  unless the  business  combination  is  approved  in a
prescribed  manner.  These  provisions could also have the effect of delaying or
preventing a change of control of Hagler Bailly,  which could  adversely  affect
the market price of its common stock.  See "DESCRIPTION OF HAGLER BAILLY CAPITAL
STOCK AND  COMPARISON  OF  STOCKHOLDER  RIGHTS  --  Anti-Takeover  Statutes  and
Provisions."

Fluctuations in Stock Price

     The  market  price  of  Hagler   Bailly's   common   stock  may   fluctuate
substantially due to a variety of factors,  including quarterly  fluctuations in
results of operations,  announcements or terminations of new services,  offices,
contracts,   acquisitions  or  strategic  alliances  by  Hagler  Bailly  or  its
competitors,  as  well  as  changes  in the  market  conditions  in the  energy,
telecommunications,  transportation  and  environmental  industries,  changes in
earnings  estimates  by analysts,  changes in  accounting  principles,  sales of
Hagler  Bailly's  common stock by existing  holders,  loss of key  personnel and
other factors.  The stock market has from time to time experienced extreme price
and volume fluctuations,  which have particularly  affected the market price for
many  companies  and  which,  on  occasion,  have been  unrelated  to  operating
performance. To the extent Hagler Bailly's performance may not meet expectations
published  by external  sources,  public  reaction  could result in a sudden and
significantly  adverse impact on the market price of Hagler Bailly's securities,
particularly on a short-term basis. In addition, such stock price volatility may
provoke the initiation of securities  litigation,  which may divert  substantial
management  resources  and may  have an  adverse  effect  on the  management  of
business  operations.  Any of these results could have a material adverse effect
on Hagler Bailly's business, operating results and financial condition.

of PHB stock.  These discussions arose following the successful public offerings
by certain of PHB's competitors. One of these was Hagler Bailly, which completed
an IPO of its common stock in July 1997.  On one or more  occasions  during this
period,  Howard W. Pifer  III,  the  Chairman  of PHB,  spoke with  Henri-Claude
Bailly,  the Chairman,  Chief Executive  Officer and President of Hagler Bailly,
about Hagler Bailly's experience with the going public process.

     During January 1998,  PHB's  management,  while  continuing to consider the
possibility of a public offering, also discussed a potential merger with another
consulting  company.  This  transaction  did not occur but  served to develop an
expanded sense of possible corporate financing objectives for PHB.

     In early  February  1998,  Mr. Pifer  telephoned  Mr. Bailly to discuss the
public  offering  experience  and  process  again.  Messrs.   Bailly  and  Pifer
tentatively agreed to meet in Los Angeles, California, on February 18.

     On February 16 and 17, PHB's  Executive  Committee  met to discuss  various
restructuring  options  available to PHB. At the end of these  meetings,  it was
resolved  that both Messrs.  Pifer and William E.  Dickenson,  the President and
Chief  Executive  Officer of PHB,  would meet with Mr.  Bailly in Los Angeles on
February  18,  to  discuss  a  possible  public  offering  of PHB or a  possible
combination with Hagler Bailly.

     At the meeting on February 18, Messrs.  Pifer and Dickenson explained PHB's
considerations  of  various  corporate  financing  alternatives,  and the  three
executives  discussed a conceptual  framework for merging PHB with Hagler Bailly
in which Hagler Bailly would purchase the outstanding stock of PHB for 7,000,000
shares of Hagler Bailly common stock.  That  afternoon,  Mr. Bailly  forwarded a
draft  confidentiality  agreement  to Mr.  Dickenson.  On  February  20, the two
companies  entered  into the  confidentiality  agreement,  following  which  PHB
forwarded  to  Mr.  Bailly  confidential   financial   information  about  PHB's
operations and future business plans.

     The following  week, Mr. Bailly and Alex  Steinbergh,  the Chief  Executive
Officer of a subsidiary of Hagler Bailly (HB Capital,  Inc.), spoke by telephone
with Messrs. Pifer and Dickenson.  During this call there was further discussion
of the  valuation of PHB as well the  significance  of merging as "equals."  Mr.
Pifer  suggested  that Mr.  Dickenson  meet with Mr.  Bailly to  discuss in more
detail how the business and management of the two firms would be integrated.

     On March 2, Mr. Dickenson met with Mr. Bailly at the latter's office.  They
addressed  and reached a  preliminary  agreement on such matters as the combined
operating  company's name (PHB Hagler  Bailly),  the roles of various members of
PHB's senior management and the desired integration steps and schedule.

     On March 3, at a regularly  scheduled  meeting,  the Hagler Bailly Board of
Directors discussed the implications,  and was supportive, of a merger with PHB.
By memorandum dated that same day, Mr.  Dickenson  advised the principals of PHB
as to Mr.  Pifer's  and his  progress  in their  exploration  of  financing  and
restructuring  options  available  to  PHB.  He  noted  that  given  the  recent
announcement  of  another  competitor's  IPO,  it would be harder  to  sustain a
competitive edge if PHB itself was not a public company.

     On March 5 and 6, Messrs.  Bailly,  Steinbergh,  Pifer and Dickenson  again
discussed (by  telephone)  the valuation of PHB.  These  discussions  came to an
agreement as to the framework of a possible business combination transaction and
the two sides  began  negotiating  a written  letter of  intent.  Mr.  Dickenson
convened a telephonic  meeting with the  Executive  Committee of PHB on March 7.
During that meeting,  it was decided that a meeting of all the principals of PHB
(including  current  stockholders and other individuals who were scheduled under
PHB's stock purchase  program to buy stock in 1998) would be held to discuss the
proposed merger.

     For the next two  weeks,  the  management  teams of Hagler  Bailly  and PHB
worked together,  with the assistance of their respective outside counsel (Hogan
& Hartson L.L.P.  and McDermott,  Will & Emery) and the public  accountants  for
both Hagler Bailly and PHB, to prepare a draft letter of intent that represented
a  proposed  merger  of  equals,  as well  as  other  merger-related  documents,
including a due diligence agreement.  In addition to the aforementioned parties,
Hagler Bailly engaged DLJ to provide an opinion  regarding the fairness,  from a
financial  point  of view,  of the  consideration  Hagler  Bailly  would  pay in
connection  with a  Merger  with  PHB.  Accordingly,  DLJ  



                                      -18-
<PAGE>


began to review the  information  PHB was  providing to Hagler Bailly as part of
the due diligence exchange of information and commenced its own inquiry into the
business operations and financial condition of PHB.

     During this period,  the purchase price of the transaction was revised from
7,000,000 to 6,800,000  shares of Hagler Bailly common stock in  recognition  of
the value of the  aggregate  370,000 share options that Hagler Bailly had agreed
to grant to certain of the PHB Managing  Directors  as part of their  employment
agreements.

     On March 20,  the Board of  Directors  of Hagler  Bailly  voted in favor of
signing a non-binding  preliminary agreement with PHB for a business combination
transaction  on the terms that had been agreed upon by the  management  teams of
the two companies during the last two weeks.

     On  March  21,  PHB  convened  its   principals  to  discuss  the  proposed
preliminary  agreement.  This  meeting  resulted  in a  consensus  in  favor  of
continuing the  negotiations  and signing the preliminary  agreement with Hagler
Bailly,  after  which  Messrs.  Dickenson  and  Bailly  signed  the  preliminary
agreement.  It was  agreed  that the  parties  would  attempt  to  complete  due
diligence and preparation of definitive merger documents by April 30.

     On March 23, Hagler Bailly and PHB issued a joint press release  announcing
the  signing  of the  preliminary  agreement.  On March 24,  Messrs.  Bailly and
Dickenson  participated in a telephone  conference call with analysts to discuss
the proposed merger.

     During  the month of April,  Messrs.  Bailly  and  Dickenson  made  various
presentations  at  Hagler  Bailly  and  PHB  offices  to  explain  the  proposed
transaction to employees of the two companies.  In addition,  during this month,
the parties, with assistance from counsel and independent auditors, negotiated a
plan of merger and merger-related  documents and conducted due diligence of each
other's business information.  As part of this process, various key personnel in
the practice areas of both companies met to discuss and compare details of their
practices.

     On April 20,  Messrs.  Pifer,  Dickenson  and R. Gene Brown (an outside PHB
Director)  met with seven of the  executive  officers  and outside  directors of
Hagler Bailly at Hagler Bailly's Arlington,  Virginia office to discuss progress
in the due diligence process and the integration of the two companies.  On April
24,  several  senior  level PHB  consultants,  along with PHB's chief  financial
officer,  made a presentation to DLJ regarding PHB's future business plans. Also
in  attendance  were  several  Hagler  Bailly  representatives  who were heavily
involved in Hagler Bailly's due diligence activities.

     On April 27, the PHB Executive Committee met in PHB's Palo Alto office. The
purpose  of  this  meeting  was to  review  the  results  of the  due  diligence
activities and the progress of the merger  negotiations.  At the end of the same
day,  Messrs.  Bailly,  Steinbergh,  Pifer  and  Dickenson  and the two other HB
Capital  principals who were performing the financial due diligence of PHB had a
telephone  conference call to review due diligence  findings and move the merger
negotiations along. On April 28, Messrs.  Bailly and Steinbergh briefed a number
of Hagler Bailly executive officers on the merger negotiation.

     On April 29, Mr.  Bailly  visited Mr.  Dickenson  in his  Washington,  D.C.
office.  They discussed various aspects of the proposed  combination,  including
management styles and the valuation of PHB. Later, during a telephone conference
call that included  Messrs.  Bailly,  Pifer,  Dickenson and Steinbergh,  Messrs.
Bailly and  Steinbergh  went through a list of outstanding  issues,  including a
possible accounting issue relating to compensation  expense. The parties settled
on a revised  valuation for PHB (which  reduced the share exchange by 200,000 to
6,600,000 shares of Hagler Bailly common stock) and also agreed to place 150,000
of these  shares  in an  escrow  account  for one year to  cover  potential  tax
obligations of PHB, if any, predating the merger.



                                      -19-
<PAGE>

     As a result of the issues discussed on this conference,  the parties agreed
that the original  April 30 target date for the signing of a  definitive  merger
agreement would be extended.

     The  following  week, on May 7, the Hagler Bailly Board of Directors met to
consider  the current  progress of the merger  negotiations,  the due  diligence
process  and a draft  of the  merger  documents.  Representatives  from  Hogan &
Hartson L.L.P. and Hagler Bailly's  independent public accountants attended part
of the meeting to brief the Board on  fiduciary,  accounting  and other  matters
regarding the proposed transaction. DLJ also presented its preliminary report on
the fairness of the price to be paid by Hagler  Bailly.  Mr. Pifer (by telephone
from  Australia)  and Mr.  Dickenson  also attended part of the meeting and were
interviewed by the Hagler Bailly Board about themselves and PHB.

     Following  this meeting,  the parties agreed to continue to extend the time
for  signing a  definitive  merger  agreement  in order to resolve  certain  due
diligence issues, to complete documentation of the transaction, to allow Ernst &
Young LLP additional  time to complete its audit of PHB's  financial  statements
for the 1997 fiscal year,  including its review of certain  compensation  charge
issues with respect to PHB stock sales in 1997 and 1998. In this regard,  on May
8, PHB engaged the services of Howard Lawson & Co. to provide a valuation of PHB
common stock on certain given dates.

     Starting  on May 18, the  parties  conducted  negotiations  of the terms of
employment  agreements for Messrs.  Dickenson and Pifer, which culminated on May
23 when Messrs. Bailly,  Dickenson,  Pifer and their respective in-house counsel
met in Washington,  D.C. to finalize the  agreements.  At this time, the parties
agreed that there would be a revision to Mr. Bailly's  employment  agreement and
that they would resolve outstanding issues in the ancillary merger documents.

     The  valuations  of PHB common stock were  completed  on June 8, 1998,  and
Ernst & Young LLP delivered its audit opinion of PHB's financial  statements for
1997 on June 10, 1998.

     Hagler Bailly sent a notice to its Board of Directors on May 29,  including
a resolution to approve the proposed  merger.  PHB sent a similar  notice to its
Board on June 1. On June 8, the  Board of  Directors  of  Hagler  Bailly  met to
consider the final merger documents.  At this meeting DLJ presented its fairness
opinion,  and the Board was advised as to its fiduciary duties and other matters
regarding the Merger. The Board unanimously approved the Merger and directed its
officers to sign the Merger Agreement on behalf of Hagler Bailly and to finalize
and file this Joint Proxy Statement/PPM for solicitation of stockholder approval
of the Share Issuance.  On June 9, the Board of Directors of PHB met to consider
the final merger  documents and approved the Merger and directed its officers to
sign the Merger  Agreement  on behalf of PHB and solicit  necessary  stockholder
approval. The parties signed the Agreement and Plan of Merger and issued a joint
press  release on June 11.  Hagler  Bailly filed this Joint Proxy  Statement/PPM
with the SEC on a preliminary  basis on July 2 and on a definitive basis on July
24.

Purpose and Effects of the Merger

     The purpose of the Merger is to enable Hagler Bailly and PHB to merge their
businesses.  If the  transactions  contemplated  by  the  Merger  Agreement  are
completed,  Merger  Sub will be  merged  with and into  PHB.  As a result of the
Merger,  Merger  Sub  will  cease  to  exist,  and  PHB  will  be the  Surviving
Corporation and will continue as a wholly owned subsidiary of Hagler Bailly.

     Hagler Bailly and PHB have  identified  several  effects of the Merger that
they believe will contribute to the success of both companies, including:



                                      -20-
<PAGE>


     Complementary Products and Services

     The combined  company will have a broader range of products and services to
offer its clients.  For example,  Hagler Bailly brings a variety of  proprietary
data bases and programs that will be useful to the strategic consulting services
PHB offers its clients in the energy industry.  PHB brings its experience in the
field of  litigation  consulting,  which  reaches a wide range of clients,  both
within and outside of the energy industry.

     Geographic Presence

     The Merger will create a company with a stronger geographic presence,  both
domestically  and  internationally.  Within the United  States,  the Merger will
expand the firm's resources and visibility in four key metropolitan  areas where
both firms currently have offices: Boston, Massachusetts;  Washington, D.C.; San
Francisco/Palo Alto, California; and Los Angeles,  California.  Internationally,
PHB's  presence in Australia  and New Zealand  will be added to Hagler  Bailly's
network of principal international offices in Argentina, Brazil, Canada, France,
Indonesia and Ireland.

     Growth and Vertical Integration

     The  Merger  will  result in a  combined  company  with a greater  depth of
consulting  service  offerings,   cross-marketing  opportunities  and  operating
resources.  In  particular,  the combined  company will benefit from the diverse
experience of a broader pool of consultants. This depth and breadth of expertise
will further enhance the quality of services available to clients.

     Improved Competitive Position in Consulting Industry

     The consulting industry has been undergoing a period of consolidation.  The
combined company will be better positioned to compete in this environment, which
will include an enhanced ability to attract and retain senior level consultants,
increased resources and a larger client base.

Structure

     The Merger will be effected by merging  Merger Sub with and into PHB,  with
PHB being the Surviving Corporation.  Each share of Merger Sub common stock, par
value $0.01 per share, issued and outstanding immediately prior to the Effective
Time shall be converted  into and exchanged for one share of common stock of the
Surviving Corporation. As a result of the Merger, Merger Sub will cease to exist
and the  Surviving  Corporation  will be a wholly  owned  subsidiary  of  Hagler
Bailly. The Surviving  Corporation's articles of organization and bylaws will be
substantially the same as PHB's immediately prior to the Effective Time.

     At  the  Effective  Time,  except  as  discussed  below,  each  issued  and
outstanding share of PHB common stock, except for any Dissenting Shares, will be
converted  automatically  into the right to receive a number of shares of Hagler
Bailly  common stock equal to  6,600,000  divided by the number of shares of PHB
common stock issued and  outstanding  immediately  prior to the Effective  Time.
Cash will be paid in lieu of fractional  shares.  Shares held as treasury  stock
will be canceled.  Under the Merger Agreement, PHB must terminate any and all of
its stock option plans under which PHB stockholders or employees have a right to
purchase  PHB  common  stock  and  each of the PHB  Options,  if any,  as of the
Effective  Time.  At or after the  Effective  Time, no one, by virtue of being a
holder of an option or right to purchase  PHB common stock or a  participant  or
former participant in any PHB stock option plan, will have any right to purchase
shares of PHB common  stock or any other equity  interest in PHB, the  Surviving
Corporation or Hagler Bailly.

     All of the shares of PHB common  stock  converted to Hagler  Bailly  common
stock  will be  canceled  automatically  and  shall  cease  to  exist,  and each
certificate  (each a "Certificate")  previously  representing any such shares of
PHB common stock shall thereafter represent the right to receive:



                                      -21-
<PAGE>


(i) the number of whole  shares of Hagler  Bailly  common stock and (ii) cash in
lieu of fractional  shares into which the shares of PHB common stock represented
by such Certificate have been converted (less the proportionate amount of Escrow
Stock).  Pursuant to the Merger  Agreement and the Escrow  Agreement (as defined
below),   Hagler   Bailly  shall   withhold  and  deposit  in  escrow  from  PHB
stockholders,  on a pro rata basis, the 150,000 Escrow Shares. See "--The Escrow
Agreement."

     Subject to the terms and conditions of the Merger Agreement, the closing of
the Merger will take place: (a) as promptly as practicable after satisfaction or
waiver of all  closing  conditions  to the  Merger or (b) such other date as the
parties may agree. If the Merger is not consummated by October 31, 1998,  either
Hagler Bailly or PHB may terminate the Merger Agreement.  However,  a party will
not  be  able  to  terminate  the  Merger  Agreement  if  it  has  breached  any
representations,  warranties,  covenants or  agreements  contained in the Merger
Agreement and the breach has caused the Merger's consummation to be delayed past
October 31, 1998.

     The parties may elect to modify the structure of the Merger. However, after
the PHB  stockholders  approve the Merger Agreement and Merger and Hagler Bailly
stockholders  approve the Share  Issuance,  the parties  cannot amend the Merger
Agreement to reduce the amount or change the type of consideration to be paid to
the PHB stockholders. As of the date of this Joint Proxy Statement/PPM,  neither
Hagler Bailly nor PHB intend to modify the structure of the Merger or the Merger
Agreement described herein.

Recommendation  of the Hagler  Bailly  Board of  Directors  and  Reasons for the
Merger

     The  Hagler  Bailly  Board  has  approved  the  Merger  Agreement  and  has
determined  that the Merger is fair to,  and in the best  interests  of,  Hagler
Bailly and its stockholders.  THE HAGLER BAILLY BOARD RECOMMENDS THAT HOLDERS OF
HAGLER  BAILLY  COMMON  STOCK  VOTE "FOR"  APPROVAL  OF THE SHARE  ISSUANCE.  In
reaching its decision to approve the Merger  Agreement,  the Hagler Bailly Board
of Directors  consulted with its outside  counsel  (regarding the legal terms of
the Merger Agreement and the Board's fiduciary  obligations in its consideration
of  the  Merger),  its  independent  auditors  (regarding   accounting  and  tax
considerations),  its financial  advisor  (regarding  the financial  aspects and
fairness,  from a financial  point of view,  of the proposed  Merger) and Hagler
Bailly's management, and considered the following:

   (i)    the Merger  will  create the  largest  publicly  held  management  and
          economic  consulting firm in the world  specializing in the energy and
          network industries, enabling Hagler Bailly to compete more effectively
          against larger, integrated management consulting firms;

   (ii)   the Merger will  combine the  particular  strengths  of each of Hagler
          Bailly and PHB in strategic and economic  analysis and  implementation
          and  will  provide  opportunities  for  significant  cross-selling  of
          services to existing  Hagler Bailly and PHB clients and for generating
          significant incremental revenues and improved margins;

   (iii)  the Merger is  expected  to be  accretive  to the  earnings  of Hagler
          Bailly;

   (iv)   the Merger  adds  talent  and depth to Hagler  Bailly  management  and
          creates a plan for management succession at Hagler Bailly;

   (v)    the Merger  will  substantially  expand  Hagler  Bailly's  presence in
          private sector work;

   (vi)   the Merger  will  expand  Hagler  Bailly  operations  internationally,
          adding offices in Australia and New Zealand,  and broaden the scope of
          Hagler Bailly's international practice;


                                      -22-
<PAGE>


   (vii)  the  Merger  is  expected  to  result  in  the   elimination  of  some
          duplicative  costs and the  achievement  of some operating and revenue
          efficiencies; and

   (viii) the Merger  consideration to be paid by Hagler Bailly is fair to its
          stockholders from a financial point of view.

     The foregoing  discussion of the information and factors  considered by the
Hagler Bailly Board is not intended to be exhaustive  but is believed to include
all material  factors  considered by the Hagler  Bailly  Board.  In reaching its
determination  to approve and recommend the Merger,  the Hagler Bailly Board did
not assign any  relative or  specific  weights to the  factors  considered,  and
individual  directors  may have given  differing  weights to different  factors.
After  deliberating  with  respect  to the  Merger  and the  other  transactions
contemplated  by the Merger  Agreement,  considering,  among other  things,  the
matters  discussed  above and the opinion of DLJ  referred to above,  the Hagler
Bailly  Board  unanimously  approved  and adopted the Merger  Agreement  and the
transactions  contemplated  thereby including the Registration  Rights Agreement
and the  Employment  Agreements  as being fair to and in the best  interests  of
Hagler Bailly and its stockholders.

Opinion of Hagler Bailly's Financial Advisor

     Hagler Bailly selected DLJ as its exclusive  financial advisor with respect
to the Merger  because DLJ is a nationally  recognized  investment  banking firm
that has substantial  experience in the consulting industry and is familiar with
Hagler Bailly,  PHB and their respective  businesses.  As part of its investment
banking  business,  DLJ is regularly  engaged in the valuation of businesses and
securities in connection with mergers,  acquisitions,  underwritings,  sales and
distributions  of  listed  and  unlisted  securities,   private  placements  and
valuations for estate, corporate and other purposes.

     As part of its role as financial advisor to Hagler Bailly, DLJ was asked to
render an opinion to the Board of Directors of Hagler  Bailly as to the fairness
to the stockholders of Hagler Bailly of the Exchange Ratio. On June 8, 1998, DLJ
delivered to the Board of Directors  of Hagler  Bailly its written  opinion (the
"DLJ  Opinion")  that, as of the date of such opinion and based upon and subject
to the assumptions,  limitations and  qualifications  set forth in such opinion,
the  Exchange  Ratio  was  fair to the  stockholders  of  Hagler  Bailly  from a
financial point of view.

     A COPY OF THE DLJ OPINION IS ATTACHED  HERETO AS ANNEX B. HOLDERS OF HAGLER
BAILLY  COMMON  STOCK ARE URGED TO READ THE DLJ OPINION IN ITS  ENTIRETY FOR THE
ASSUMPTIONS  MADE,  THE MATTERS  CONSIDERED AND THE LIMITS OF THE REVIEW MADE BY
DLJ IN CONNECTION WITH SUCH OPINION.

     The DLJ Opinion was prepared for the Hagler  Bailly Board of Directors  and
is directed  only to the fairness to the  stockholders  of Hagler  Bailly of the
Exchange  Ratio  from a  financial  point  of  view.  The DLJ  Opinion  does not
constitute a  recommendation  to any  stockholder as to how to vote on the Share
Issuance  in  connection  with the  Merger  at the  Hagler  Bailly  stockholders
meeting.  DLJ did not  make  any  recommendation  as to the  form or  amount  of
consideration  to  be  paid  by  Hagler  Bailly  pursuant  to  the  transactions
contemplated  by the Merger  Agreement.  Such  consideration  was  determined in
negotiations between Hagler Bailly and PHB. DLJ's opinion does not constitute an
opinion as to the prices at which Hagler Bailly common stock will actually trade
at any time. No restrictions  or limitations  were imposed by Hagler Bailly upon
DLJ with respect to the investigations made or the procedures followed by DLJ in
rendering the DLJ Opinion.

     In arriving at its opinion,  DLJ reviewed a draft dated June 5, 1998 of the
Merger  Agreement.  DLJ also reviewed  financial and other  information that was
publicly  available  or  furnished  to it by Hagler  Bailly  and PHB,  including
information  provided  during  discussions  with their  respective  managements.
Included  in such  information  provided to DLJ were (1)  preliminary  unaudited
financial statements of PHB for the year ended December 31, 1997 and the quarter
ended March 31, 1998 prepared by the  management  of PHB, (2) certain  financial
projections of PHB for the period



                                      -23-
<PAGE>


beginning  January  1,  1998  and  ending  December  31,  2002  prepared  by the
management of PHB and (3) certain financial projections of Hagler Bailly for the
period  beginning  January 1, 1998 and ending  December 31, 2002 prepared by the
management of Hagler Bailly.  In addition,  DLJ compared  certain  financial and
securities  data of Hagler  Bailly and PHB with various  other  companies  whose
securities  are traded in the public  markets,  reviewed  the  historical  stock
prices and trading  volumes of Hagler Bailly  common stock and  conducted  other
financial  studies,  analyses and  investigations as DLJ deemed  appropriate for
purposes of its opinion.

     In rendering the DLJ Opinion,  DLJ relied upon and assumed the accuracy and
completeness of all of the financial and other information that was available to
it from public  sources,  that was  provided  to it by Hagler  Bailly and PHB or
their respective representatives or that was otherwise reviewed by DLJ. DLJ also
assumed that (1) the financial  projections,  including  estimates of synergies,
supplied to it were reasonably  prepared on bases  reflecting the best currently
available estimates and judgments of the managements of Hagler Bailly and PHB as
to the future  operating  and  financial  performance  of Hagler Bailly and PHB,
respectively,  (2) the final  audited  financial  statements of PHB for the year
ended December 31, 1997 and the final unaudited financial  statements of PHB for
the quarter ended March 31, 1998 will not differ materially from the preliminary
unaudited  statements furnished to DLJ, with the exception of any changes as the
result of the  non-recurring,  non-cash stock  compensation  charges and (3) the
Merger will qualify as a tax-free  reorganization  and for  pooling-of-interests
accounting  treatment.  Subsequent  to the  delivery  of the  DLJ  Opinion,  DLJ
reviewed  the  final  audited  financial  statements  of PHB for the year  ended
December 31, 1997 and the final  unaudited  financial  statements of PHB for the
quarter ended March 31, 1998 and determined that they did not differ  materially
from the preliminary unaudited statements furnished to DLJ prior to the delivery
of the  DLJ  Opinion,  with  the  exception  of  changes  as the  result  of the
non-recurring,  non-cash  stock  compensation  charges.  DLJ has not assumed any
responsibility for making any independent  evaluation or appraisal of the assets
or  liabilities  of  Hagler  Bailly  or  PHB  or  for  making  any   independent
verification of any  information  reviewed by it. DLJ relied as to certain legal
matters on advice of counsel to Hagler Bailly.

     The DLJ Opinion is  necessarily  based on economic,  market,  financial and
other conditions as they existed on, and on the information made available to it
as of, the date of the DLJ Opinion.  Although subsequent developments may affect
its opinion, DLJ does not have any obligation to update,  revise or reaffirm its
opinion.

     The following is a summary of the material analyses presented by DLJ to the
Hagler Bailly Board of Directors at its June 8, 1998 meeting in connection  with
rendering the DLJ Opinion.  All market information used in the analyses is as of
the close of business on June 4, 1998. All financial information for PHB used in
the  analyses  are pro forma to back out  incentive  compensation  (bonus  above
standard levels) that will not be paid post-Merger and  non-recurring,  non-cash
stock compensation  charges. All financial information for Hagler Bailly used in
the  analyses  are pro forma to back out  non-recurring,  non-cash  compensation
charges.

     Earnings per Share Impact Analysis

     Using the financial  information and  projections  provided to DLJ by PHB's
and Hagler Bailly's  respective  managements,  DLJ reviewed the impact on Hagler
Bailly's 1998,  1999, 2000 and 2001 projected  earnings per share resulting from
the Merger. DLJ's analysis separately considered  accretion/dilution (i) without
giving effect to the synergies  estimated by Hagler Bailly's management and (ii)
giving  effect  to the  synergies.  The  amounts  of  incremental  revenue  from
synergies  estimated by Hagler  Bailly,  and assumed by DLJ,  were $3.8 million,
$23.8 million,  $38.3 million and $46.1 million for 1998,  1999,  2000 and 2001,
respectively.  Actual results  achieved by the combined  companies may vary from
the amounts used and the  variations  may be material.  This analysis  indicated
that the  Merger  would be  accretive  to 1998,  1999,  2000 and 2001  projected
earnings  per share  with or  without  synergies.  Assuming  no  synergies,  the
accretive  effect of the Merger on projected  earnings per share  ("EPS") was an
estimated  24.2%,  15.2%,  12.9%  and  8.6%,  for  1998,  1999,  2000 and  2001,
respectively.

     Analysis of Certain Publicly Traded Companies for PHB

     To provide contextual data and comparative market information, DLJ compared
selected  historical  earnings and  operating  and  financial  ratios for PHB to
corresponding  data and  ratios of certain  business  services  companies  whose
securities are publicly  traded.  In conducting  its analysis,  DLJ compared the
ratios  implied  by the  Exchange  Ratio to the ratios  implied  from the market
valuation of publicly traded companies  selected by DLJ (the "Business  Services
Companies") based upon quantitative factors which DLJ deemed relevant based upon
its  experience  in  the  business  services  industry.  The  Business  Services
Companies were separated into information technology ("IT") and non-IT companies
based  upon  their  business  focus.  The  non-IT  Business  Services  Companies
included:  Hagler Bailly, Inc., Charles River Associates  Incorporated and LECG,
Inc. The IT Business  Services  Companies  included:  The Metzler  Group,  Inc.,
Forrester Research, Inc., and Superior Consultant Holdings Corporation. Although
DLJ used these  companies for  comparison  purposes,  none of such  companies is
directly  comparable  to PHB.  Accordingly,  a complete  analysis of the results
cannot be limited to a quantitative  review and involves complex  considerations
and judgments concerning differences in financial and operating  characteristics
of the Business  Services  Companies  and other  factors  which could affect the
public trading value of the Business Services  Companies as well as that of PHB.
All  financial  information  for the Business  Services  Companies  used in this
analysis are pro forma to exclude certain  non-recurring charges and for certain
other  adjustments.  Data and ratios  considered by DLJ  included:  the ratio of
enterprise  value to (i) latest 12 months  ("LTM")  revenues,  (ii) LTM earnings
before interest expense, income taxes,  depreciation and amortization ("EBITDA")
and (iii) LTM earnings before interest expense and income taxes ("EBIT") and the
ratio of market price to (i) LTM EPS, (ii) 1998 estimated median EPS as reported
by I/B/E/S  International,  Inc. ("I/B/E/S") and (iii) 1999 estimated median EPS
as reported by I/B/E/S.  Enterprise value is defined as the sum of the principal
amount of a company's  long-term  debt and minority  interests  in  consolidated
subsidiaries plus the market value of its equity securities less excess cash.

     For non-IT Business  Services  Companies,  the ratio of enterprise value to
LTM  revenues  ranged  from 2.8x to 4.3x,  and was 3.1x for PHB at the  Exchange
Ratio.  The ratio of enterprise  value to LTM EBITDA ranged from 18.0x to 31.5x,
and was 20.3x for PHB at the Exchange  Ratio.  The ratio of enterprise  value to
LTM EBIT  ranged  from  19.6x to 36.3x,  and was  23.3x for PHB at the  Exchange
Ratio.  The ratio of market price to LTM EPS ranged from 27.8x to 43.8x, and was
35.7x for PHB at the Exchange Ratio. The ratio of market price to 1998 estimated
EPS ranged from 27.3x to 31.4x, and was 20.5x for PHB at the Exchange Ratio. The
ratio of market price to 1999 estimated EPS ranged from 21.9x to 25.8x,  and was
16.8x for PHB at the Exchange Ratio.

     For IT Business  Services  Companies,  the ratio of enterprise value to LTM
revenues  ranged from 4.9x to 6.5x, and was 3.1x for PHB at the Exchange  Ratio.
The ratio of enterprise  value to LTM EBITDA ranged from 29.5x to 45.8x, and was
20.3x for PHB at the Exchange Ratio.  The ratio of enterprise  value to LTM EBIT
ranged from 31.0x to 55.9x,  and was 23.3x for PHB at the  Exchange  Ratio.  The
ratio of market  price of LTM EPS ranged from 43.1x to 60.6x,  and was 35.7x for
PHB at the  Exchange  Ratio.  The ratio of market  price to 1998  estimated  EPS
ranged from 35.8x to 44.6x,  and was 20.5x for PHB at the  Exchange  Ratio.  The
ratio of market price to 1999 estimated EPS ranged from 27.1x to 33.9x,  and was
16.8x for PHB at the Exchange Ratio.

     Discounted Cash Flow Analysis

     DLJ  performed a discounted  cash flow  analysis of Hagler  Bailly and PHB,
using their respective  management's  estimates of future performance and future
results of operations including and excluding synergies.

     For Hagler Bailly,  DLJ selected a range of terminal  multiples of 11.0x to
13.0x  EBITDA and a range of weighted  average cost of capital of 12.9% to 16.9%
based upon its  subjective  judgments  about,  among other  things,  the capital
markets,  Hagler  Bailly's  prospects and the business  services  industry.  The
terminal multiple  represents an estimate of the value of Hagler Bailly's future
free


                                      -25-
<PAGE>


cash flows at December 31, 2002. Assuming a terminal multiple of 12.0x EBITDA in
2002 and a weighted  average cost of capital of 14.9%,  this analysis  implied a
per share value of Hagler Bailly of $29.71.


     For PHB,  DLJ  selected  a range of  terminal  multiples  of 11.0x to 13.0x
EBITDA and a range of weighted  average  cost of capital of 12.9% to 16.9% based
upon its subjective  judgments about,  among other things,  the capital markets,
PHB's  prospects  and the business  services  industry.  The  terminal  multiple
represents  an estimate of the value of PHB's future free cash flows at December
31,  2002.  Assuming a terminal  multiple of 12.0x EBITDA in 2002 and a weighted
average cost of capital of 14.9%, this analysis implied a per share value of PHB
of  $43.62  and an  implied  Exchange  Ratio of 1.47x  without  synergies.  With
synergies,  this  analysis  implied  a per share  value of PHB of $53.96  and an
implied Exchange Ratio of 1.82x.

     Contribution Analysis

     DLJ reviewed the relative  contribution  to the combined  company of Hagler
Bailly  and PHB with  respect  to total  revenues,  EBITDA,  EBIT and net income
without  giving  effect to synergies.  At the Exchange  Ratio,  shareholders  of
Hagler Bailly and PHB will own approximately 59.8% and 40.2%,  respectively,  of
the fully diluted common stock of the combined company.  The projections made by
PHB's and Hagler Bailly's managements  indicate,  for the years 1998-2002,  that
Hagler Bailly would provide from 61.4% to 71.0% of combined revenues; from 47.1%
to 58.5% of  combined  EBITDA;  from 47.1% to 58.6% of combined  EBIT;  and from
48.3% to 59.0% of  combined  net income.  On a  corresponding  basis,  PHB would
provide  from  29.0% to  38.6%  of  combined  revenues;  from  41.5% to 52.9% of
combined  EBITDA;  from 41.4% to 52.9% of combined EBIT; and from 41.0% to 51.7%
of combined net income.

     Analysis of Certain Other Publicly Traded Companies for Hagler Bailly

     To provide  contextual data and comparative  market  information on whether
Hagler Bailly common stock is fairly valued by the market, DLJ compared selected
historical  earnings and  operating  and  financial  ratios for Hagler Bailly to
corresponding  data and  ratios of certain  business  services  companies  whose
securities are publicly  traded.  In conducting  its analysis,  DLJ compared the
ratios implied from the market  valuation of Hagler Bailly to the ratios implied
from the market  valuation  of the  Business  Services  Companies.  The Business
Services  Companies were separated into IT and non-IT companies based upon their
business focus. The non-IT Business Services Companies  included:  Charles River
Associates  Incorporated  and LECG,  Inc.  The IT  Business  Services  Companies
included:  The Metzler  Group,  Inc.,  Forrester  Research,  Inc.,  and Superior
Consultant  Holdings   Corporation.   Although  DLJ  used  these  companies  for
comparison  purposes,  none of such  companies is directly  comparable to Hagler
Bailly.  Accordingly,  a complete analysis of the results cannot be limited to a
quantitative review and involves complex considerations and judgments concerning
differences in financial and operating  characteristics of the Business Services
Companies and other  factors which could affect the public  trading value of the
Business  Services  Companies as well as that of Hagler  Bailly.  All  financial
information  for the Business  Services  Companies  used in this analysis is pro
forma  to  exclude   certain   non-recurring   charges  and  for  certain  other
adjustments. Data and ratios considered by DLJ included: the ratio of enterprise
value to (i) LTM  revenues,  (ii) LTM EBITDA and (iii) LTM EBIT and the ratio of
market  price to (i) LTM EPS,  (ii) 1998  estimated  median EPS as  reported  by
I/B/E/S and (iii) 1999 estimated  median EPS as reported by I/B/E/S.  Enterprise
value is defined as the sum of the  principal  amount of a  company's  long-term
debt and minority  interests in consolidated  subsidiaries plus the market value
of its equity securities less excess cash.

     For non-IT Business  Services  Companies,  the ratio of enterprise value to
LTM revenues ranged from 3.6x to 4.3x, and was 2.8x for Hagler Bailly. The ratio
of enterprise  value to LTM EBITDA ranged from 18.0x to 31.5x, and was 23.4x for
Hagler  Bailly.  The ratio of enterprise  value to LTM EBIT ranged from 19.6x to
36.3x,  and was 27.7x for Hagler  Bailly.  The ratio of market  price to LTM EPS
ranged from 27.8x to 43.8x, and was 36.4x for Hagler Bailly. The ratio of market
price


                                      -26-
<PAGE>


to 1998  estimated  EPS  ranged  from  27.3x to 31.4x,  and was 30.6x for Hagler
Bailly.  The ratio of market  price to 1999  estimated  EPS ranged from 21.9x to
25.8x, and was 23.6x for Hagler Bailly.

     For IT Business  Services  Companies,  the ratio of enterprise value to LTM
revenues ranged from 4.9x to 6.5x, and was 2.8x for Hagler Bailly.  The ratio of
enterprise  value to LTM EBITDA  ranged  from 29.5x to 45.8x,  and was 23.4x for
Hagler  Bailly.  The ratio of enterprise  value to LTM EBIT ranged from 31.0x to
55.9x,  and was 27.7x for Hagler  Bailly.  The ratio of market  price to LTM EPS
ranged from 43.1x to 60.6x, and was 36.4x for Hagler Bailly. The ratio of market
price to 1998 estimated EPS ranged from 35.8x to 44.6x, and was 30.6x for Hagler
Bailly.  The ratio of market  price to 1999  estimated  EPS ranged from 27.1x to
33.9x, and was 23.6x for Hagler Bailly.

     The summary set forth above  describes the material  analyses  presented by
DLJ to the Hagler Bailly Board of Directors on June 8, 1998 in  connection  with
the  DLJ  Opinion.  The  preparation  of a  fairness  opinion  involves  various
determinations  as to the most  appropriate  and  relevant  methods of financial
analysis and the  application of these methods to the  particular  circumstances
and,  therefore,   such  an  opinion  is  not  readily  susceptible  to  summary
description.  Each of the analyses  conducted by DLJ was carried out in order to
provide a  different  perspective  on the  Merger and to add to the total mix of
information  available.  DLJ  did  not  form  a  conclusion  as to  whether  any
individual analysis, considered in isolation,  supported or failed to support an
opinion as to fairness from a financial point of view.  Rather,  in reaching its
conclusion,  DLJ  considered  the results of the analyses in light of each other
and ultimately reached its opinion based on the results of all analyses taken as
a whole,  without  placing  particular  reliance  or  weight  on any  individual
analysis.  Accordingly,  notwithstanding  the separate factors summarized above,
DLJ believes that its analysis must be considered as a whole and that  selecting
portions of its analysis and the factors  considered by it, without  considering
all analyses and factors,  could  create an  incomplete  view of the  evaluation
process  underlying  its  opinions.  The  analyses  performed  by  DLJ  are  not
necessarily  indicative  of  actual  values  or  future  results,  which  may be
significantly more or less favorable than suggested by such analyses.

     Pursuant to the terms of an engagement letter,  Hagler Bailly has agreed to
pay DLJ a fee of $350,000 for rendering its fairness opinion.  Hagler Bailly has
also agreed to reimburse DLJ for certain  out-of-pocket  expenses (including the
reasonable   fees  and  expenses  of  DLJ's  counsel)  in  connection  with  its
engagement,  and to  indemnify  DLJ and certain of its related  persons  against
certain  liabilities in connection  with its engagement,  including  liabilities
under the federal  securities  laws. The terms of the fee arrangement  with DLJ,
which DLJ and Hagler  Bailly  believe  are  customary  in  transactions  of this
nature,  were  negotiated at arm's length between Hagler Bailly and DLJ. DLJ has
performed  investment  banking and other  services for Hagler Bailly in the past
and has been compensated for such services.  DLJ was the lead manager for Hagler
Bailly's July 1997 IPO.  Pursuant to the terms of the engagement  letter between
the  Company  and  DLJ,  DLJ  shall  have  the  right  to act as  lead  managing
underwriter to the Company in connection with any public equity financing by the
Company which is effected within 12 months following consummation of the Merger.

     In the  ordinary  course  of  business,  DLJ  actively  trades  the  equity
securities  of Hagler  Bailly for its own  account  and for the  accounts of its
customers and accordingly, may at any time hold a long or short position in such
securities.

Recommendation of the PHB Board of Directors and Reasons for the Merger

     The Board of Directors of PHB has  approved  the Merger  Agreement  and has
determined that the Merger is fair to, and in the best interests of, PHB and its
stockholders.  THE PHB BOARD OF DIRECTORS  RECOMMENDS THAT HOLDERS OF PHB COMMON
STOCK VOTE "FOR" THE MERGER  AGREEMENT AND THE MERGER PROVIDED FOR THEREIN.  The
PHB Board of  Directors  believes  that the Merger  will  enable  holders of PHB
common  stock to realize  increased  value due to the premium  over  price,  net
income per share and book value per share of PHB common stock.  The PHB Board of
Directors also believes that the Merger may enable PHB



                                      -27-
<PAGE>


stockholders to participate in  opportunities  for appreciation of Hagler Bailly
common stock. In reaching its decision to approve the Merger Agreement,  the PHB
Board  consulted  with its  outside  counsel  (regarding  the legal terms of the
Merger and the PHB Board's  fiduciary  obligations in its  consideration  of the
Merger) as well as with the  management  of PHB and  considered  the  following,
which are all of the material  factors  considered,  both from a short-term  and
long-term perspective:

   (i)    the combined company will have an improved competitive position in the
          consulting industry;

   (ii)   the Merger will create a more diverse geographic presence;

   (iii)  the  combined  company  will  offer a broader  range of  products  and
          services; and

   (iv)   the Merger will result in a combined  company with a greater  depth of
          service offerings, marketing opportunities and resources.

     The foregoing  discussion of the information and factors  considered by the
PHB Board is not  intended  to be  exhaustive  but is  believed  to include  all
material  factors  considered  by the PHB  Board,  from  both a  short-term  and
long-term  perspective.  In reaching its  determination to approve and recommend
the Merger, the PHB Board did not assign any relative or specific weights to the
factors considered, and individual directors may have given differing weights to
different  factors.  After deliberating with respect to the Merger and the other
transactions  contemplated by the Merger Agreement and considering,  among other
things,  the matters  discussed  above,  the PHB Board  approved and adopted the
Merger Agreement and the transactions  contemplated thereby as being fair to and
in the best interests of PHB and its stockholders.

Closing and Effective Time

     The Merger will become effective when the articles of merger are filed with
the Secretary of State of the Commonwealth of Massachusetts and the Secretary of
State of Delaware in accordance with applicable law. The articles of merger will
be filed as  promptly  as possible  after the  parties  receive  all  reasonable
assurances  as to the  tax  and  accounting  treatment  of the  Merger,  certain
documents,  opinions, consents and certificates are received, certain agreements
are entered, and Hagler Bailly stockholders have approved the Share Issuance and
PHB stockholders have approved the Merger Agreement and the Merger, provided the
aggregate  number of  Dissenting  Shares is 10% or less.  PHB and Hagler  Bailly
expect that the Merger will be  consummated in the summer of 1998, or as soon as
possible after all stockholder approvals are obtained.

     The Merger  Agreement  provides that at the Effective Time, each issued and
outstanding  share  of PHB  common  stock  (excluding  PHB  treasury  stock  and
Dissenting  Shares) will be converted  automatically into the right to receive a
number of shares of Hagler Bailly common stock equal to (i) 6,600,000 divided by
(ii) the number of shares of PHB common stock issued and outstanding immediately
prior to the  Effective  Time.  All shares of PHB capital stock held as treasury
stock by PHB  immediately  prior to the  Effective  Time  will be  canceled  and
extinguished without any conversion.

     Because the market  price of Hagler  Bailly  common stock and the number of
outstanding  shares of PHB common stock are subject to change,  the market value
of the shares of Hagler Bailly common stock that PHB  stockholders  will receive
in the Merger may  materially  increase  or  decrease  prior to the  Merger.  No
assurance  can be given as to the market price of Hagler  Bailly common stock at
the time of the Merger or the number of shares of PHB common  stock  outstanding
at the Effective Time. See "MARKET PRICES AND DIVIDENDS."

     Certificates representing fractions of shares of Hagler Bailly common stock
will not be issued. Under the Merger Agreement, in lieu of a fractional share of
Hagler Bailly common stock,  each PHB stockholder will be entitled to receive an
amount of cash equal to the product of (i) such fractional 



                                      -28-
<PAGE>


part of Hagler Bailly common stock multiplied by (ii) the reported closing price
of a share of Hagler  Bailly common stock on the Nasdaq Stock Market on the last
business day prior to the closing date.

     The  conversion  of PHB common stock held by  stockholders  of PHB into the
right to  receive  shares of Hagler  Bailly  common  stock  (and cash in lieu of
fractional  shares) will occur  automatically  upon  consummation of the Merger.
Pursuant to the Merger  Agreement,  at or prior to the  Effective  Time,  Hagler
Bailly will deposit or cause to be deposited  with the Exchange  Agent,  for the
benefit of the  holders of the  certificates  representing  shares of PHB common
stock to be  exchanged  pursuant to the Merger,  certificates  representing  the
shares  of  Hagler  Bailly   common  stock  to  be  issued  (less   certificates
representing the Escrow Shares) and the cash in lieu of fractional  shares to be
paid in the Merger.

Exchange of PHB Common Stock Certificates

     Promptly after the Effective  Time,  certificates  representing  PHB common
stock shall be canceled,  and,  simultaneously  with such  cancellation,  Hagler
Bailly  shall issue  certificates  with respect to the canceled PHB common stock
for  each  PHB   stockholder.   All  such   certificates   (the  "Merger   Stock
Certificates") shall be registered in the name of each PHB stockholder and shall
represent  the total number of shares of Hagler  Bailly  common  stock  issuable
pursuant to the Merger in respect of shares of PHB common stock held by such PHB
stockholder  (less the PHB  stockholder's  proportionate  interest in the Escrow
Shares).  A separate  certificate,  representing  the Escrow Shares (the "Escrow
Stock Certificate"), shall be issued in the name of the Escrow Agent (as defined
below) as nominee of each PHB stockholder.

     Prior to or promptly after the Effective Time, the Exchange Agent will mail
to each holder of record of PHB common  stock a form letter of  transmittal  and
instructions   for  use  in  surrendering   the  Certificates  in  exchange  for
certificates  representing the shares of Hagler Bailly common stock and the cash
in lieu  of  fractional  shares  into  which  the  shares  of PHB  common  stock
represented  by such  Certificate  or  Certificates  will  have  been  converted
pursuant  to the Merger  Agreement.  Upon the  surrender  of a  Certificate  for
exchange and  cancellation  to the Exchange  Agent,  together with the letter of
transmittal,  duly executed,  the holder of such Certificate will be entitled to
receive in exchange for such  Certificate:  (i) a certificate  representing that
number  of whole  shares  of  Hagler  Bailly  common  stock  to  which  such PHB
stockholder will have become entitled pursuant to the Merger Agreement (less the
holder's pro rata share of the Escrow Shares) and (ii) a check  representing the
amount of cash in lieu of fractional  shares,  if any, that such PHB stockholder
has the right to receive in respect of the Certificate  surrendered  pursuant to
the Merger  Agreement.  The  Certificate  surrendered  will be canceled.  At the
Effective  Time,  Hagler  Bailly will issue and transfer to the Escrow Agent the
Escrow Stock  Certificate to be held in escrow. As to Hagler Bailly common stock
received in the Merger,  a PHB stockholder  will not be entitled to any dividend
or other  distribution  payable to Hagler Bailly common stock record  holders on
any date  after  the  Effective  Time,  unless  and  until  the PHB  stockholder
surrenders a  Certificate  in exchange for such shares of Hagler  Bailly  common
stock.  No  interest  will be paid or accrued on the cash in lieu of  fractional
shares and unpaid  dividends and  distributions,  if any,  payable to holders of
Certificates.

Certificates  should not be  returned  to PHB with the  enclosed  proxy card and
should be forwarded to the  Exchange  Agent only after  receipt of the letter of
transmittal.

     A Material Adverse Effect as to Hagler Bailly or PHB means, as the case may
be,  any  material  adverse  effect  on the  assets or the  business,  financial
condition or results of operations of Hagler Bailly or PHB and their  respective
subsidiaries taken as a whole.

Conduct of Business Pending The Merger

     The Merger  Agreement  contains  certain  restrictions on the operations of
Hagler  Bailly,  PHB and their  respective  subsidiaries  prior to the Effective
Time. In general,  the Merger Agreement  obligates each of Hagler Bailly and PHB
and their  subsidiaries,  respectively  to: (i) operate their  businesses in the
ordinary  course  consistent  with past  practices and preserve  their  business
organizations, maintain their rights and contracts, retain the services of their
personnel and maintain relationships with suppliers, contractors,  customers and
others; (ii) keep their property in good repair and (iii) maintain substantially
their current insurance levels. If a party requests from the other permission to
deviate from any of the above restrictions, the other party must consider such a
request  in good faith and not  unreasonably  withhold  or delay its  consent to
deviate.

     The Merger Agreement  provides that until the closing,  Hagler Bailly,  PHB
and their respective  subsidiaries  shall not,  without  permission of the other
party,  or unless the proposed  transaction was disclosed or contemplated by the
Merger Agreement:  (a) increase  director,  officer or employee  compensation or
grant severance or termination pay other than as currently obligated by existing
severance contracts or enter into or modify severance or employment  agreements,
except in the ordinary course of business and consistent with past practice; (b)
adopt or amend  any  employee  benefit  plan or  arrangement,  except  as may be
required  by law;  (c)  declare  or pay any  dividend  on,  or



                                      -30-

make any other  distribution in respect of, any of its capital stock; (d) effect
any reorganization or recapitalization;  (e) redeem, repurchase or reacquire any
of its capital stock or effect certain changes pertaining to or issuances of its
capital stock or other securities, with certain exceptions; (f) acquire or merge
with another entity or acquire  another  entity's  assets unless in the ordinary
course of business  and  consistent  with past  practice  or make  extraordinary
capital expenditures, except acquisitions,  mergers or other alliances involving
Hagler Bailly for which the valuation is less than $20.0 million; (g) dispose of
or encumber  material  assets unless in the ordinary  course and consistent with
past practice;  (h) propose or adopt any amendments to its charter  documents or
bylaws (other than the Certificate Amendment); (i) change its accounting method;
(j) take certain action  relating to, or make certain changes  regarding,  taxes
(except as may be required by law or generally accepted accounting  principles);
(k) prepay certain debt or trade payables;  (l) enter into or modify  materially
certain material  contracts;  (m) take action that would cause or be expected to
cause any representations or warranties to be untrue or conditions to the Merger
not to be satisfied or (n) agree to do any of the  foregoing.  Hagler Bailly and
PHB have also agreed, that unless they agree otherwise, for a period of one year
from the date of the Merger Agreement neither will solicit the other's employees
for employment if the Merger does not close.

Expenses

     Each  party  shall pay all costs and  expenses  incurred  by such  party in
connection with the Merger.

Representations and Warranties

     Under  the  Merger  Agreement,  Hagler  Bailly  and PHB have  made  certain
representations  and warranties to one another,  including those with regard to:
(i) their  organization,  existence,  good standing and status and that of their
significant  subsidiaries;  (ii) their respective  charter documents and bylaws;
(iii)  capital  stock and  capitalization;  (iv) the  existence of the necessary
corporate  power and authority  required to enter into the Merger  Agreement and
the ancillary  agreements thereto;  (v) obtaining required filings and consents;
(vi) the veracity of their  financial  statements,  and in Hagler  Bailly's case
confirmation  that certain items have been filed with the SEC; (vii) the absence
of certain changes or events;  (viii) legal proceedings and material  contracts;
(ix) environmental matters; (x) employee matters,  benefit plans and ERISA; (xi)
compliance with applicable  laws;  (xii) the possession of certain  licenses and
permits;   (xiii)  properties  and  assets;   (xiv)  insurance   matters;   (xv)
intellectual  property  rights;  (xvi)  investment  company  status;  (xvii) tax
matters;  (xviii) the veracity of the information supplied for inclusion in this
Joint Proxy  Statement/PPM  and certain other  material  information,  including
certain  books and  records;  (xix)  transactions  with  related  parties;  (xx)
approval  of  the  transactions   contemplated  by  Merger  Agreement  by  their
respective  Boards  and  stockholder   approval  and  (xxi)  broker's  fees  and
commissions.  PHB has also represented and warranted that there are no more than
35 PHB stockholders who are not "accredited" as such term is defined in Rule 501
of Regulation D under the Securities Act.

Nonsurvival of Representations, Warranties and Agreements

     The  representations,  warranties,  covenants and  agreements in the Merger
Agreement (and in any certificate delivered in connection with the Closing) have
been deemed to be  conditions  to the Merger and will not survive the  Effective
Time or  termination  of the Merger  Agreement.  However,  the agreements in the
Merger Agreement relating to the mechanics, consideration and procedures for the
Merger, the conversion of securities and the exchange of certificates  (Articles
I and II) and the equal  treatment of PHB  employees  after the Merger  (Section
7.8) will survive the Effective Time indefinitely.  Also, provisions relating to
special tax indemnification (Section 10.2) will survive for a period of one year
after the  Effective  Time,  and  agreements  relating to  non-solicitation  and
confidentiality as they relate to the other provisions surviving  termination of
the Merger Agreement  (Section 11.7) and fees and expenses  (Section 11.12) will
survive termination of the Merger Agreement indefinitely.

Other Agreements

     Pursuant  to the  Merger  Agreement,  Hagler  Bailly  and PHB have  reached
agreement with respect to various other matters,  including, but not limited to:
(i) providing  information,  access to  information  and  confidentiality;  (ii)
taking all steps  necessary  to duly call,  give  notice  of,  convene  and hold
meetings of PHB's and Hagler Bailly's respective  stockholders and recommend the
approval of the  proposals  in  connection  with the Merger;  (iii)  causing the
Surviving  Corporation to maintain the indemnification  obligations of PHB as to
its officers and  directors;  (iv) using their  reasonable  best efforts to take
action  to  consummate  the  Merger;  (v)  making  public  announcements;   (vi)

Bailly);  (vii) the equal treatment of PHB and Hagler Bailly employees after the
Merger  regarding the elimination of positions and for 1998, the continuation of

a pooling-of-interests for financial accounting purposes; (ix) PHB's delivery to
Hagler Bailly of certain certificates obtained from PHB stockholders;  (x) using
their  reasonable  best  efforts  to cause the Merger to be  accounted  for as a

The Support Agreements

     In  connection  with the  Merger,  Hagler  Bailly,  Merger Sub and  certain
directors and executive  officers of Hagler Bailly,  who beneficially own in the
aggregate  approximately  27% of the outstanding  shares of Hagler Bailly common
stock, have entered into the Hagler Bailly Support Agreement, and PHB and all of
PHB's directors,  who beneficially own in the aggregate approximately 85% of the
PHB common  stock,  have entered into the PHB Support  Agreement  (together  the
"Support Agreements").  The Support Agreements provide, among other things, that
the stockholders who have signed them have agreed to vote their shares of common
stock of: (i) Hagler Bailly in favor of the Share Issuance and (ii) PHB in favor
of the Merger Agreement,  the Merger and the other transactions  contemplated by
the Merger  Agreement.  See "THE HAGLER  BAILLY  SPECIAL  MEETING"  and "THE PHB
SPECIAL MEETING."

     The Support Agreements also provide that the signing  stockholders will not
encumber  or dispose of or enter any  contract  to  encumber or dispose of their
Hagler Bailly common stock or PHB common stock,  as the case may be, or any such
stock they may acquire in the future.  The Support  Agreements also provide that
the signing  stockholders  will vote  against:  (a)  approval or adoption of any
extraordinary  corporate  transactions  that are not  contemplated by the Merger
Agreement;   (b)  resolutions  which  would  prevent,  delay  or  frustrate  the
transactions  or  Hagler  Bailly's  or  PHB's,  as the case may be,  obligations
contemplated by the Merger Agreement and (c) any action which would constitute a
material breach of the Merger  Agreement.  The Support  Agreements also restrict
the signing stockholders' ability to solicit or respond favorably to indications
of interest or negotiate with third parties concerning  extraordinary  corporate
transactions or furnish nonpublic information in connection therewith.

The Affiliate Agreements

     Each of Hagler  Bailly and PHB must deliver to the other,  on or before the
Effective  Time, from each of its affiliates,  a written  agreement  relating to
future  sales of Hagler  Bailly  common  stock  after the Merger is closed  (the
"Hagler Bailly  Affiliate  Agreement" or the "PHB  Affiliate  Agreement," as the
case  may  be;  collectively,  the  "Affiliate  Agreements").  Pursuant  to  the
Affiliate  Agreements,  the affiliates have agreed not to dispose of or encumber
any of their  shares of Hagler  Bailly  common  stock  until  financial  results
covering at least 30 days of  post-Merger  combined  operations of Hagler Bailly
and PHB are publicly reported.  The parties to the Merger have required that the
affiliates  enter the  Affiliate  Agreements  in order to help  ensure  that the
Merger  qualifies  as for  pooling-of-interests  accounting  treatment.  See "--
Accounting Treatment."



                                      -32-
<PAGE>


The Escrow Agreement

     Under a separate  escrow  agreement to be signed at or before the Effective
Time (the "Escrow  Agreement"),  Hagler Bailly will deposit with an escrow agent
150,000  shares of Hagler Bailly common stock  issuable to PHB  stockholders  in
connection  with  the  Merger.  The  Merger  Agreement  provides  that  each PHB
stockholder who receives Hagler Bailly common stock in the Merger will indemnify
and hold harmless Hagler Bailly,  the Surviving  Corporation and any entity that
is a member of an "affiliated  group",  as defined in the Code,  with respect to
certain  losses of PHB imposed  upon or incurred by such  entities or members of
such affiliated group relating to certain  taxation  obligations with respect to
periods  ending  on or prior  to  December  31,  1997.  Each  PHB  stockholder's
liability  under this provision is capped at the value of the PHB  stockholder's
pro rata share of the Escrow Shares.

     William E. Dickenson,  President and Chief  Executive  Officer of PHB, will
serve as a representative  for the PHB stockholders  under the Escrow Agreement.
The Escrow Agreement  provides that if any of the indemnified  parties mentioned
above  asserts  a  claim  for   indemnification   regarding   certain   taxation
obligations,  a portion of the Escrow Shares equal in value to the amount of the
claim will be released to the indemnified party, provided Mr. Dickenson does not
object.  If Mr. Dickenson,  as representative of the PHB stockholders,  objects,
the portion of the Escrow  Shares will be released  only if a court of competent
jurisdiction  or arbitrator so orders,  or Mr.  Dickenson  later consents to the
release.  No Escrow  Shares shall be  distributed  to Hagler Bailly until losses
have been incurred by Hagler Bailly.

     The Escrow  Shares will  remain in escrow for one year after the  Effective
Time. During this one year period, the PHB stockholders will be able to vote the
Escrow Shares in proportion to their respective pro rata interests. Also, Hagler
Bailly  will pay any cash  dividends  or other  distributions  payable to Hagler
Bailly  stockholders to the PHB stockholders on a pro rata basis.  After the one
year period has elapsed and any claims are  resolved,  any  remaining  shares of
Escrow Shares will be released to the PHB stockholders on a pro rata basis.

The Employment Agreements

     Hagler Bailly has entered into employment  agreements with Messrs.  Bailly,
Dickenson  and Pifer which will  become  effective  one day after the  Effective
Time. Mr.  Bailly's  employment  agreement will replace his existing  employment
contract  with Hagler  Bailly.  See "HAGLER  BAILLY  EXECUTIVE  COMPENSATION  --
Employment  Arrangements."  Each agreement  specifies the various positions that
each of the  respective  parties  will  hold  with  Hagler  Bailly  or  PHB,  as
applicable, after the Merger. See "--Post-Merger Management of Hagler Bailly and
the  Surviving  Corporation"  and  "--Post-Merger  Boards of Directors of Hagler
Bailly and the Surviving Corporation." The agreements' terms end on July 3, 2000
in the case of Mr. Bailly,  and three years after the Effective Time in the case
of Messrs. Dickenson and Pifer. Under these agreements,  each of Messrs. Bailly,
Dickenson and Pifer will receive for their respective  services,  initial annual
base  salaries of: (i) $393,750 in the case of Mr.  Bailly and (ii)  $345,592 in
the case of  Messrs.  Dickenson  and  Pifer.  Base  salaries  will be subject to
increase  each  January 1 by an amount  that is no less than the greater of five
percent over the annual rate of base salary in effect for the preceding year and
the increase in the Consumer Price Index for the year.  Each of Messrs.  Bailly,
Dickenson  and Pifer is entitled to a bonus for each  calendar  year equal to an
amount determined by the Executive  Compensation  Committee of the Hagler Bailly
Board. As part of the employment  agreements,  Messrs.  Dickenson and Pifer will
each be granted  options to purchase 92,000 shares of Hagler Bailly common stock
at fair market value as of the Effective  Time.  Each of the parties is entitled
to receive,  from time to time,  options to purchase  Hagler Bailly common stock
pursuant to Hagler  Bailly's  option  plans as  determined  by the Stock  Option
Committee of the Hagler  Bailly Board and is entitled to  participate  in all of
the benefit  programs  which are  presently  or may in the future be provided by
Hagler Bailly, in the case of Mr. Bailly, and Hagler Bailly subsidiaries, in the
case of Messrs. Dickenson and Pifer.


                                      -33-
<PAGE>


     Each  agreement  provides  that if Hagler  Bailly  materially  breaches the
agreement or upon  termination of the employee by Hagler Bailly without cause or
upon change in control  (as defined in the  agreements),  the  employee  will be
entitled to an  immediate  lump sum payment  equal to four times his annual base
salary and payment of his annual base salary over the three years  following the
termination.  Each of the agreements  also contain certain  non-competition  and
non-solicitation  provisions  which will be in effect during the term of each of
the agreements.

     PHB has entered into employment  agreements with 37 of its current Managing
Directors  and  Directors  which will  become the  obligation  of the  Surviving
Corporation  or its  subsidiaries  at the Effective  Time. PHB will enter into a
senior advisor agreement with one current Managing Director.  The agreements are
for a term of three years in the case of PHB Managing  Directors,  and two years
in the case of PHB Directors.  Under these agreements,  each of the PHB Managing
Directors  and PHB  Directors  will  receive  initial  base  salaries of between
$230,256 and $287,664 in the case of PHB Managing  Directors,  between  $172,536
and $201,240 in the case of PHB Directors, and discretionary bonuses. As part of
these  agreements,  certain  of the  Managing  Directors  will  receive,  in the
aggregate,  options to purchase  186,000 shares of Hagler Bailly common stock at
fair market value at the Effective Time.

     Each of these  employment  agreements  may be  terminated  by the Surviving
Corporation (a) upon death,  (b) for permanent  disability or (c) for cause, and
by the employee (d) upon a material  breach by the Surviving  Corporation or (e)
at the will of the employee.  The agreements  provide that if termination occurs
under (a), (c) or (e),  then the  employee is not  entitled to any  compensation
that would accrue after the  termination  date. The agreements also provide that
if an employee is terminated  under (b) or (d), the employee will be entitled to
payment of compensation and benefits for a period equal to six months of service
or the remaining term of the agreement, whichever is longer. The agreements also
contain non-solicitation and other restrictive covenants.

The Registration Rights Agreement

     The shares of Hagler  Bailly  common  stock to be issued in the Merger will
not be registered  under the Securities Act and will not be freely  transferable
under the Securities Act.  Accordingly,  current holders of PHB common stock who
receive  shares of Hagler  Bailly  common  stock in the Merger may not sell such
shares,  except  pursuant  to an  effective  registration  statement  under  the
Securities Act covering such shares, or in compliance with an exemption from the
registration  requirements  of the Securities Act. Such  stockholders  must also
comply with all applicable state securities laws.

     At or before the Effective  Time,  Hagler  Bailly and the PHB  stockholders
will enter into the Registration Rights Agreement.  Pursuant to the terms of the
Registration Rights Agreement,  the PHB stockholders will be entitled to certain
piggyback  registration  rights  under the  Securities  Act with  respect to the
shares of Hagler  Bailly  common stock that they  receive in the Merger.  In the
event that Hagler  Bailly  proposes to register  shares of Hagler  Bailly common
stock  under the  Securities  Act (except on certain  SEC  registration  forms),
either for its account or for the  account of other  security  holders,  the PHB
stockholders  will be entitled to receive  notice of and include their shares in
such registration.  These piggyback  registration  rights are subject to certain
conditions  and  limitations,  among  them the right of the  underwriters  of an
offering  to limit the number of shares of Hagler  Bailly  common  stock held by
Hagler  Bailly  stockholders  with  registration   rights,   including  the  PHB
stockholders,  to be included in such registration.  Also, if at any time Hagler
Bailly arranges for a sale of Hagler Bailly common stock by security  holders in
a private  placement  transaction,  then  Hagler  Bailly  shall  provide the PHB
stockholders  with notice of and an  opportunity to participate in such intended
sale on a pro rata basis with the other selling security holders.

     The  Registration  Rights  Agreement  also  provides that if, during the 12
months  following  the Merger,  Hagler  Bailly has not made a registered  public
offering  which  is a  piggyback  registration  under  the  Registration  Rights
Agreement,  then  the PHB  stockholders  collectively  will be  entitled  to one
request  for  registration  of  their  Hagler  Bailly  common  stock  under  the
Securities Act (a "Demand  



                                      -34-
<PAGE>


Registration").  Hagler  Bailly  will  only be  obligated  to  effect  a  Demand
Registration if PHB stockholders  owning at least 50% of the securities  covered
by the Registration Rights Agreement have so requested.

Post-Merger Management of Hagler Bailly and the Surviving Corporation

     The Merger Agreement and the Employment Agreements provide that certain PHB
and Hagler  Bailly  personnel  will  assume the  following  positions  after the
Merger.

     Mr.  Dickenson will become  Executive  Vice  President and Chief  Operating
Officer of Hagler Bailly one day after the Effective  Time. He will have overall
responsibility for all Hagler Bailly operations and specific  responsibility for
all the combined United States and Canadian  operations of PHB and Hagler Bailly
and for the  integration of PHB and Hagler Bailly.  Mr.  Dickenson will become a
member  of the  Management  Committee  of  Hagler  Bailly  Consulting,  Inc.,  a
subsidiary  of Hagler  Bailly.  Mr.  Dickenson  will hold the  position of Chief
Executive  Officer  of  PHB  until  its  full  integration  with  Hagler  Bailly
Consulting at which time he will hold the position of Chief Executive Officer of
PHB Hagler Bailly (as defined below).  Mr.  Dickenson will become  President and
Chief Executive Officer of Hagler Bailly as of January 1, 2000.

     Alain Streicher,  currently a director and Senior Vice President and Acting
Chief Operating  Officer of Hagler Bailly and a director and the Chief Executive
Officer of Hagler Bailly  Services,  Inc., a subsidiary of Hagler  Bailly,  will
hold the  position  of  Executive  Vice  President  of  Hagler  Bailly as of the
Effective  Time and will  have  specific  responsibility  for all  international
(other  than  Canada)  operations  of  Hagler  Bailly  and PHB.  Messrs.  Pifer,
Dickenson, Fred Baird, Neill Freeman, and James Speyer (all current directors of
PHB) will each hold the position of executive  officer of Hagler  Bailly one day
after the Effective Time.

     After the Effective  Time,  Hagler Bailly and PHB  anticipate the following
management designations:  (i) Jassi Cheema, currently Chief Executive Officer of
Hagler Bailly  Consulting and President of TB&A Group, Inc.  ("TB&A"),  a Hagler
Bailly  subsidiary,  will become a member of PHB's Executive  Committee and (ii)
Hagler Bailly will create an Executive  Management Committee of no more than six
executive officers to provide strategic advice to the Chief Executive Officer of
Hagler Bailly. See "HAGLER BAILLY -- Directors and Executive Officers."

Post-Merger Boards of Directors of Hagler Bailly and the Surviving Corporation

     The Merger  Agreement  also  provides for the  following as to the Board of
Directors of Hagler Bailly.

     At the Effective  Time,  the number of members of the Board of Directors of
Hagler  Bailly shall be increased  by two members.  One day after the  Effective
Time,  Howard  Pifer  will  become a director  of Hagler  Bailly in the class of
directors  the term for  which  expires  in 2001 and  Chairman  of the  Board of
Directors of Hagler Bailly until  December 31, 1999. In addition,  one day after
the effective time, R. Gene Brown will become a director of Hagler Bailly in the
class of directors the term for which expires in 2000.

     After the  Effective  Time,  Mr.  Dickenson  will be  elected by the Hagler
Bailly  Board of  Directors to fill any vacancy on the Board that arises and, in
any event,  will be nominated by the Hagler  Bailly Board of Directors not later
than the 1999 annual  meeting of  stockholders  of Hagler Bailly to serve in the
class of directors  the term for which  expires in 2002.  Mr. Bailly will become
Chairman of the Board of Hagler Bailly on January 1, 2000. See "HAGLER BAILLY --
Directors and Executive Officers."

Post-Merger Organizational Designations

     At the Effective Time, Hagler Bailly and PHB anticipate the following other
organizational  designations.  The  Strategy and  Economics  practices of Hagler
Bailly  Consulting  and TB&A and the



                                      -35-
<PAGE>


practices  of  PHB  will  be  coordinated  and  integrated,  and  Hagler  Bailly
Consulting  and TB&A will be merged  with and into PHB,  on or after  January 1,
1999, but no later than April 1, 1999. The surviving  corporation of such merger
will be named PHB Hagler Bailly,  Inc. ("PHB Hagler  Bailly").  Also,  after the
Effective Time, the existing offices of Hagler Bailly and PHB will be identified
both as Hagler  Bailly  (the main name of the  company)  and PHB Hagler  Bailly.
Hagler Bailly and PHB have agreed that research and  information-based  services
and  information  technology  services  can be  managed  and go to market  under
separate  Hagler Bailly units such as Hagler  Bailly  Research and Hagler Bailly
Solutions.  The  parties  have  also  reached  an  understanding  regarding  the
elimination of Hagler Bailly's public sector  environmental  practice that is in
conflict with the combined entity's environmental consulting practice as well as
the  creation  of a  conflicts  committee  to review  any  actual  or  perceived
conflicts  among future and  existing  clients in the  environmental  consulting
practice area.

Termination and Amendment of the Merger Agreement

     Hagler Bailly or PHB may  terminate the Merger  Agreement at any time prior
to the  Effective  Time,  and the  Merger  may be  abandoned:  (a) by the mutual
consent  of  PHB  and  Hagler  Bailly;  (b) by  Hagler  Bailly  if any of  PHB's
representations,  warranties,  covenants or agreements becomes materially untrue
such that the conditions  precedent to the obligations of Hagler Bailly to close
will not be satisfied and PHB has not cured within 30 days following  receipt of
written  notice of such breach;  (c) by PHB if any of Hagler  Bailly's or Merger
Sub's  representations,  warranties,  covenants or agreements becomes materially
untrue such that the  conditions  precedent to the  obligations  of PHB to close
will not be satisfied  and either  Hagler  Bailly or Merger Sub, as the case may
be, has not cured within 30 days  following  receipt by Hagler Bailly of written
notice  of such  breach;  (d) by  either  Hagler  Bailly  or PHB if any  decree,
permanent injunction,  judgment, order or other action by any court of competent
jurisdiction or any government entity preventing or prohibiting  consummation of
the Merger  shall have  become  final and  nonappealable;  (e) by either  Hagler
Bailly or PHB if the Effective  Time has not occurred on or prior to October 31,
1998,  upon giving notice to the other party (unless such date shall be extended
by the mutual  written  consent  of the  parties);  provided,  that the right to
terminate  under this provision shall not be available to any party whose breach
of  representations,  warranties,  covenants or agreements has been the cause of
the failure of the Effective Time to occur by such date or the inability of such
condition  to be  satisfied;  or (f) by  either  Hagler  Bailly or PHB if either
party's  stockholders fail to give their respective required approvals.  For any
breach of a representation  or warranty set forth in the Merger  Agreement,  the
sole remedy shall be termination of the Merger  Agreement,  by the non-breaching
party.  For  any  breach  of any  other  covenant  or  agreement  in the  Merger
Agreement,  the  non-breaching  party will be entitled to  terminate  the Merger
Agreement and seek any  available  remedies at law or in equity for such breach.
If a party terminates the Merger Agreement  pursuant to (f) above, and the other
party enters into certain  transactions with another party, then such party will
be  obligated  to pay the  other  party an  alternative  transaction  fee of $10
million.

     Under certain circumstances,  either Hagler Bailly or PHB may terminate the
Merger  Agreement,  upon five business days' prior notice to the other, if, as a
result of a Superior  Proposal (as defined below)  received by such party from a
person other than a party to the Merger Agreement or any of its affiliates,  the
Board of Directors  of such party  determines  in good faith that its  fiduciary
obligations  under  applicable  law  require  that  such  Superior  Proposal  be
accepted.  Such a  determination  must be made in good faith and on the basis of
advice of counsel that such action is  necessary  for such Board of Directors to
act in a manner  consistent  with its fiduciary  duties under  applicable  laws.
Also, prior to any such  termination,  the terminating party must negotiate with
the other party to the Merger  Agreement to make such  adjustments  in the terms
and  conditions  of the Merger  Agreement  as would enable such party to proceed
with  the  Merger.  Termination  for  a  Superior  Proposal  will  obligate  the
terminating  party to pay an alternative  transaction  fee of $10 million to the
non-terminating  party.  Under the Merger  Agreement,  a Superior Proposal is an
acquisition proposal the Board of Directors of Hagler Bailly or PHB, as the case
may be, concludes in good faith (after consultation with its financial advisors)
is  reasonably  capable  of being  completed,  taking  into  account  all legal,
financial, regulatory and other aspects of the proposal and the person



                                      -36-
<PAGE>


making the proposal,  and would,  if consummated,  result in a transaction  more
favorable to Hagler Bailly's or PHB's  stockholders,  as the case may be, from a
financial and strategic point of view than the  transaction  contemplated by the
Merger  Agreement.  A  Superior  Proposal  shall  not  include  any  acquisition
involving  Hagler Bailly for which the valuation is less than $20 million or any
other  transaction  disclosed  by Hagler  Bailly to PHB  pursuant  to the Merger
Agreement.

     The parties may amend the Merger  Agreement by mutual agreement at any time
prior to the Effective Time.  However,  after PHB and Hagler Bailly stockholders
approve the Merger Agreement and Share Issuance,  respectively, no amendment may
be made which would reduce the amount or change the type of  consideration  into
which each share of PHB common stock shall be converted in the Merger.

Federal Income Tax Consequences

     It is intended  that the Merger will  qualify as a tax-free  reorganization
within the  meaning of Code  Section 368 for federal  income tax  purposes.  PHB
stockholders  generally should not recognize gain or loss for federal income tax
purposes as a result of exchanging  their PHB common stock for the Hagler Bailly
common stock  issued in the Merger.  Consummation  of the Merger is  conditioned
upon  Ernst & Young  LLP  furnishing  Hagler  Bailly  and  PHB  with  reasonable
assurances  that the  Merger  will so  qualify.  The Merger  Agreement  does not
require either party to obtain a ruling from the Internal  Revenue Service as to
the tax consequences of the Merger.

     If the Merger qualifies as a tax-free  reorganization within the meaning of
Section  368 of the Code,  then:  (i)  except as  discussed  in (iv)  below with
respect to cash  received in lieu of a fractional  share of Hagler Bailly common
stock, a PHB stockholder  should  recognize no gain or loss upon the exchange of
PHB common stock for Hagler Bailly common stock pursuant to the Merger; (ii) the
tax basis of the Hagler Bailly common stock received by a PHB stockholder in the
Merger should be the same as the stockholder's tax basis in the PHB common stock
surrendered in exchange therefor;  (iii) the holding period of the Hagler Bailly
common stock  received by a PHB  stockholder  in the Merger  should  include the
holding  period  of the  PHB  common  stock  surrendered  in  exchange  therefor
(assuming the PHB common stock was held as a capital asset); (iv) the receipt by
a PHB  stockholder of cash in lieu of fractional  shares of Hagler Bailly common
stock should be treated as if the fractional  shares were distributed as part of
the Merger and then were  redeemed by Hagler  Bailly,  with these cash  payments
treated as distributions in full payment in exchange for the stock redeemed,  as
provided  in Section  302(a) of the Code and (v) neither  Hagler  Bailly nor PHB
should recognize any gain or loss as a result of the Merger.

     The Merger Agreement  provides that each PHB stockholder will indemnify and
hold harmless  Hagler  Bailly,  Surviving  Corporation  and any entity that is a
member of an "affiliated group", as defined in the Code, with respect to certain
losses of PHB  imposed  upon or  incurred  by such  entities  or members of such
affiliated group relating to certain PHB tax liabilities. Each PHB stockholder's
liability under this provision is capped at the PHB stockholder's pro rata share
of the Escrow Shares.

     The preceding  discussion is intended only as a summary of certain  federal
income tax  consequences  of the  Merger  and does not  purport to be a complete
analysis or discussion of all potential tax effects relevant thereto. Holders of
PHB common stock are urged to consult  their own tax advisors as to the specific
tax  consequences  to  them  of  the  Merger,  including  tax  return  reporting
requirements,  the applicability and effect of federal,  state, local, and other
applicable tax laws and any proposed changes of the tax law.

Accounting Treatment

     The Merger is intended to qualify as a pooling-of-interests  for accounting
and financial reporting purposes. One of the closing conditions to the Merger is
that Hagler  Bailly and PHB shall 



                                      -37-
<PAGE>


have received a letter from Ernst & Young LLP, independent public accountants to
both parties, in form and substance reasonably satisfactory to Hagler Bailly and
PHB, to the effect that the  transactions  contemplated by the Merger  Agreement
will qualify for  pooling-of-interests  accounting treatment.  Hagler Bailly and
PHB  anticipate  that  Ernst  &  Young  LLP  will  deliver  letters  at  Closing
indicating,  among other things, its concurrence in Hagler Bailly's management's
conclusion  that no  conditions  exist that would  preclude  Hagler  Bailly from
accounting   for   the   Merger   as   a    pooling-of-interests.    Under   the
pooling-of-interests  method of accounting,  the recorded assets and liabilities
of PHB will be carried  forward to the Surviving  Corporation  at their recorded
amounts. Revenues and expenses of the Surviving Corporation and therefore Hagler
Bailly will include  revenues and expenses of PHB for the entire  fiscal year of
the Surviving  Corporation and Hagler Bailly in which the Merger occurs, and the
reported  revenues and expenses of PHB for prior  periods will be combined  with
those of Hagler Bailly, whose financial  statements will then be restated.  Each
of PHB and Hagler  Bailly must  deliver to the other on or before the  Effective
Time,  the Affiliate  Agreements.  The Affiliate  Agreements  restrict  sales by
affiliates  after the Merger is  consummated  in order to help  assure  that the
Merger qualifies as a pooling-of-interests. See "-- The Affiliate Agreements."

Dissenters' Appraisal Rights

     If the Merger closes,  a PHB  stockholder who does not vote in favor of the
Merger and the Merger Agreement and who follows the procedures  prescribed under
Massachusetts  law may require the  Surviving  Corporation  to pay for the "fair
value," as determined in accordance with Massachusetts  Corporation Law, for the
PHB common stock held by such stockholder. The following is a summary of certain
features  of  the  relevant  sections  of  Massachusetts  Corporation  Law,  the
provisions of which are set forth in full in Annex E hereto, and such summary is
subject to and  qualified  in its entirety by reference to such law. In order to
exercise such statutory  appraisal rights,  strict compliance with the statutory
provisions is required.  Each PHB  stockholder who wants to exercise such rights
should carefully review and comply with such provisions.

     A PHB stockholder  who desires to pursue his or her appraisal  rights must:
(i) file a written  objection to the Merger with PHB in accordance  with Section
86 of Massachusetts  Corporation Law before the taking of the stockholders' vote
on the  Merger  and the  Merger  Agreement,  stating  that such PHB  stockholder
intends  to demand  payment  for his or her  shares if the Merger and the Merger
Agreement are approved and the Merger is  consummated;  (ii) refrain from voting
in favor of the Merger and the Merger  Agreement  and (iii) make written  demand
(the  "Demand") to the Surviving  Corporation  for payment for his or her shares
within 20 days of the date of mailing of a notice by the  Surviving  Corporation
to objecting  stockholders  that the Merger has become  effective  (which notice
will be sent  within  10 days of the  Effective  Date).  The  written  objection
described in clause (i) above should be  delivered to Barbara  Levine,  Clerk of
PHB. It is  recommended  that such  objection be sent by registered or certified
mail, return receipt requested.

     A stockholder  who files the required  written  objection with PHB prior to
the  stockholder  vote need not vote against the Merger,  but a vote in favor of
the Merger will constitute a waiver of such  stockholders'  statutory  appraisal
rights. If a stockholder returns a proxy which is signed but on which no vote is
specified as to the proposal on the Merger  Agreement,  and thereafter  does not
revoke such proxy,  it will be voted for the Merger,  and the  stockholder  will
have waived his or her appraisal rights. In addition,  a vote against the Merger
does not by itself constitute a written objection.

     The value of the PHB  common  stock  will be  determined  initially  by the
Surviving Corporation and the dissenting  stockholder.  If, during the period of
30 days after the  expiration of the period during which the Demand may be made,
the Surviving  Corporation and the dissenting  stockholder  fail to agree on the
value of the PHB common  stock,  either of them may file a bill in equity in the
Superior  Court of  Middlesex  County,  Massachusetts,  asking  that  the  Court
determine  the value.  The bill in equity must be filed within four months after
the date of expiration of the foregoing 30-day period.  If the bill in equity is
timely  filed,  the Court or an  appointed  special  master



                                      -38-
<PAGE>


will  hold a  hearing.  After  the  hearing,  the  Court  shall  enter a  decree
determining  the fair value of the PHB common  stock with  respect to all of the
dissenting  stockholders  and shall  order  the  Surviving  Corporation  to make
payment of such value,  with  interest,  from the date of the vote approving the
Merger and the Merger Agreement,  if any, to all of the stockholders entitled to
said  payment,  upon  transfer  by  them  to the  Surviving  Corporation  of the
certificates representing the PHB common stock held by said stockholders.

     The "fair value" of the PHB common stock could be more than, the same as or
less than the Merger consideration.  For appraisal proceeding purposes, value is
determined  as of the day  before  the  approval  of the  Merger  and the Merger
Agreement by the  stockholders,  excluding any element of value arising from the
expectation or accomplishment of the Merger.

     The  enforcement  by a  stockholder  of the request to receive  payment for
shares of PHB common stock as provided under the applicable statutory provisions
is an  exclusive  remedy  except  that such remedy does not exclude the right of
stockholders to bring or maintain an appropriate  proceeding to obtain relief on
the ground that said corporate  action will be or is illegal or fraudulent as to
said  stockholder.  In Coggins v. New England Patriots  Football Club, Inc., 397
Mass. 525 (1986),  however,  the Massachusetts  Supreme Judicial Court held that
dissenting  stockholders  are not  limited to the  statutory  remedy of judicial
appraisal where violations of fiduciary duty exist.

     A final  judgment  by the Court or a special  master  determining  the fair
value  of the PHB  common  stock  could be  binding  on and  enforceable  by PHB
stockholders who have perfected their statutory  appraisal rights,  even if such
fair  value  were  determined  to be  less  than  the  Merger  consideration.  A
stockholder who perfects rights as a dissenting  stockholder will not, after the
Effective  Date,  be  entitled  to  notices of  meetings,  to vote or to receive
dividends.

     Each share of PHB common  stock held by  stockholders  who seek to exercise
appraisal rights and, after the Effective Time, fail to perfect or lose any such
right to  appraisal,  shall be treated as a share that had been  converted as of
the  Effective  Time into the right to receive  Hagler  Bailly  common  stock as
provided in the Merger  Agreement. 

     The  respective  obligations  of Hagler  Bailly and PHB to  consummate  the
Merger are conditioned  upon,  among other things,  that the aggregate number of
Dissenting Shares be no more than 10% of the PHB common stock outstanding at the
closing.

Interests of Certain Persons in the Merger

     After the Effective Time, Dr. Brown and Mr. Pifer will become Hagler Bailly
directors.  See "--Post  Merger  Boards of  Directors  of Hagler  Bailly and the
Surviving  Corporation." As an outside  director,  Dr. Brown will be entitled to
stock   option   grants   under  Hagler   Bailly's   stock   option  plan.   See
"MANAGEMENT--Director  Compensation."  The  Employment  Agreements  provide that
after the Merger,  Messrs. Pifer and Bailly will hold various positions with the
combined company, receive certain compensation, and be eligible for lump sum and
severance payments in certain circumstances,  and that Mr. Pifer will receive an
option to purchase  92,000  shares of Hagler  Bailly  common  stock.  See "--The
Employment  Agreements."  Also, under the Merger Agreement,  Messrs.  Cheema and
Streicher  will  hold  various   positions  with  the  combined   company.   See
"--Post-Merger Management of Hagler Bailly and the Surviving Corporation."

(1)  On December 31, 1996,  PHB  liquidated  its wholly owned  subsidiary in the
     U.K.  Of PHB's loss of $662,609 in 1996,  $548,757  represented  cumulative
     foreign currency translation losses which had previously been recorded as a
     separate component of the PHB's shareholders' equity. In 1997, $328,070 was
     recorded  as  management's  estimate  of  the  uncollectable  net  proceeds
     resulting from the liquidation.

(2)  In   connection   with  an  amendment  to  the  Stock  Option  Plan  and  a
     reclassification  of its common stock,  each  effective  December 31, 1996,
     Hagler  Bailly  incurred  non-recurring,  non-cash  charges  to  operations
     amounting  to  $4.6  million  for  options  and  $1.6  million  for  stock,
     respectively, in 1996. In connection with a stock bonus to an employee, the
     Company incurred a non-cash  compensation charge to operations in the first
     quarter of 1997 of $65,000.  PHB common stock issued or subject to issuance
     under subscriptions  receivable entered into within 12 months preceding the
     closing of the Merger are presumed to have been issued in  contemplation of
     the proposed transaction and are required to be accounted for at their fair
     market value at date of issuance.  Accordingly, PHB has recognized noncash,
     nontax-deductible  compensation  charges as of December  31, 1997 and March
     31, 1998 of  $9,884,800  and  $2,164,800,  respectively,  representing  the
     difference  between fair value and the book value of shares of common stock
     then issuable.

(3)  The  statement of operations  data for the years ended  December 31 and the
     three   months  ended  March  31,  1997   include   performance   incentive
     compensation  PHB paid to its senior staff  members in excess of a standard
     bonus  set for  their  respective  staff  levels.  The  excess  performance
     incentive  compensation was included in PHB's Cost of services and Selling,
     general  and  administrative  and  was  $39,000,  $2,931,000,   $6,260,000,
     $9,588,000 and $7,294,000 for the years ended 1993,  1994,  1995,  1996 and
     1997,  respectively,  and  $1,823,000  for the three months ended March 31,
     1997.

Comparative Per Share Data

     The following table sets forth certain  historical per share data of Hagler
Bailly and PHB and combined  per share data on a pro forma  basis,  after giving
effect to the Merger on a pooling-of-interests  basis (and assuming the issuance
of 1.2759  shares of Hagler  Bailly  common  stock in the Merger in exchange for
each share of PHB common stock).  This data should be read in  conjunction  with
the selected consolidated financial data and the pro forma combined consolidated
financial data and the separate historical financial statements of Hagler Bailly
and PHB  included  elsewhere  in this Joint Proxy  Statement/PPM.  The pro forma
combined  consolidated  data are not  necessarily  indicative  of the  operating
results or financial  position  that would have been  achieved if the Merger had
been  consummated  as of the  beginning of the periods  presented,  nor are they
necessarily indicative of the future operating results or financial positions of
Hagler Bailly and PHB.

     Neither Hagler Bailly nor PHB paid dividends  during the three-year  period
ended December 31, 1997 or the three-month period ended March 31, 1998.

                      SELECTED CONSOLIDATED FINANCIAL DATA

     The following tables set forth selected  consolidated  financial data as of
December 31 in each of the years 1993  through 1997 and for each of the years in
the  five-year  period  ended  December  31,  1997.  The  selected  consolidated
financial  data for the years ended December 31, 1993 and 1994 have been derived
from the audited  financial  statements of Hagler Bailly's  predecessor  company
described below in the section entitled,  "HAGLER BAILLY MANAGEMENT'S DISCUSSION
AND ANALYSIS OF FINANCIAL  CONDITION  AND RESULTS OF  OPERATIONS."  The selected
consolidated  financial  data for the year ended  December  31, 1995 include the
combined  financial  data  of  the  predecessor  company  derived  from  audited
financial  statements from January 1, 1995 to May 25, 1995 and the  consolidated
financial data of Hagler Bailly from May 26, 1995 to December 31, 1995,  derived
from Hagler Bailly's audited  consolidated  financial  statements.  The selected
consolidated  financial  data as of December 31, 1996 and 1997 have been derived
from the audited  consolidated  financial  statements of Hagler  Bailly.  Hagler
Bailly's  prior years have been  restated to include the  acquisition  of Apogee
Research,  Inc. and TB&A Group, Inc. The selected financial data presented below
as of March 31, 1998 and for the  three-month  periods  ended March 31, 1997 and
1998,  are derived from the  unaudited  financial  statements  of Hagler  Bailly
which,  in the opinion of Hagler  Bailly  management,  have been prepared on the
same basis as Hagler  Bailly's  audited  consolidated  financial  statements and
include  all  adjustments,  consisting  only  of  normal  recurring  adjustments
necessary for a fair  presentation  of the results of  operations  and financial
position for and as of such periods. The results of operations for prior periods
are not  necessarily  indicative  of the results that may be expected for future
periods.  The  historical  financial  data  should be read in  conjunction  with

(1)  Effective  May  25,  1995,  the  management  of  RCG/Hagler  Bailly,   Inc.

     ("RCG"),  acquired  all of the  voting  stock  of  RCG/Hagler  Bailly.  The
     statements of operations  data include the  operations of Apogee  Research,
     Inc. and TB&A for all periods presented.
(2)  The  statements  of  operations  data for the year ended  December 31, 1996
     includes  the  following  expenses:  (i) $0.5  million of Cost of services,
     representing  that  portion  of  officer  compensation  that  exceeded  the
     compensation that would have been paid had the compensation plan adopted in
     January 1997 been in effect for all of 1996; (ii) $6.2 million of Stock and
     stock  option   compensation   representing  the  non-recurring,   non-cash
     compensation  expense in connection  with the amendment to the Stock Option
     Plan and (iii) a reclassification of Hagler Bailly's common stock described
     in footnote 3 below.  The net impact of the  foregoing  on Hagler  Bailly's
     Statement  of  Operations  for the  year  ended  December  31,  1996 was to
     decrease Income before income tax expense by $7.7 million and Net income by
     $6.6 million,  with Income tax expense calculated at a combined federal and
     state income tax rate of 40.0%.  Excluding  the  foregoing,  Income  before
     income tax  expense  for the year ended  December  31, 1996 would have been
     $4.9 million and Net income would have been $2.9 million.
(3)  In   connection   with  an  amendment  to  the  Stock  Option  Plan  and  a
     reclassification  of its common stock,  each  effective  December 31, 1996,
     Hagler  Bailly  incurred  non-recurring,  non-cash  charges  to  operations
     amounting  to  $4.6  million  for  options  and  $1.6  million  for  stock,
     respectively,  in 1996.  In  connection  with a stock bonus to an employee,
     Hagler Bailly incurred a non-cash  compensation charge to operations in the
     first quarter of 1997 of $65,000.

Financial  Condition  and  Results of  Operations  which are not  historical  in

statements"  for the purposes of the safe harbor  provided by Section 21E of the
Securities   Exchange   Act  of  1934,   as  amended   by  Public  Law   104-67.
Forward-looking  statements may be identified by words  including  "anticipate,"
"believe," "estimate," "expect" and similar expressions.  Hagler Bailly cautions
readers that  forward-looking  statements,  including without limitation,  those
relating  to  Hagler  Bailly's  future  business  prospects,  revenues,  working
capital,  liquidity  and income are subject to certain  risks and  uncertainties
that would cause actual results to differ materially from those indicated in the
forward-looking statements, due to several important risk factors, some of which
are identified in this Joint Proxy  Statement/PPM.  Hagler Bailly  undertakes no
obligation to release publicly any revisions to these forward-looking statements
that may be made to reflect future events or circumstances.

Overview

     Hagler  Bailly is a worldwide  provider of  consulting,  research and other
professional    services   to   corporations    and   governments   on   energy,
telecommunication, transportation and the environment. The predecessor of Hagler
Bailly was founded in February  1980 as Hagler  Bailly & Company,  Inc. In July,
1984 it was acquired by RCG International,  Inc. ("RCG") an indirect  subsidiary
of Reliance Group Holdings, Inc. and in 1987 was renamed RCG/Hagler Bailly, Inc.
In May 1995,  the  management  of  RCG/Hagler  Bailly  completed the purchase of
RCG/Hagler  Bailly from RCG (the  "Management  Buy-Out"),  and the  successor to
RCG/Hagler  Bailly became a wholly-owned  subsidiary of Hagler  Bailly.  In July
1997, Hagler Bailly completed an IPO of shares of its common stock.

     Hagler  Bailly's  revenues  represent the total of all revenues  related to
contracts, including revenues associated with professional staff, subcontractors
and  independent  consultants.  Consulting  revenues  represent  the  amount  of
contract revenue associated with billings by Hagler Bailly's professional staff.
Subcontractor   and  other   revenues   represent   revenues   associated   with
subcontractors  and  independent  consultants,  as well as  travel  and per diem
reimbursements from clients.

     Hagler  Bailly  derives  substantially  all of its  revenues  from fees for
professional  services.  Clients are typically  invoiced on a monthly basis. The
majority of revenues are billed at standard daily rates or cost-plus fixed-fees.
Revenues  from  standard   daily  rate   contracts  are  recognized  at  amounts
represented  by the  agreed-upon  billing  amounts and costs are  recognized  as
incurred.  Revenue from cost-plus fixed-fee contracts is recognized as costs are
incurred on the basis of direct costs plus  allowable  indirect  costs and a pro
rata  portion of estimated  fee.  The  remainder of the revenues are billed on a
fixed-bid  basis.  Revenues from  fixed-bid type contracts are recognized on the
percentage-of-completion  method of accounting with costs and estimated  profits
included in contract  revenues  based on the  relationship  that contract  costs
incurred bear to management's  estimate of total contract costs. Losses, if any,
are  accrued  when they  become  known and the amount of the loss is  reasonably
determinable.  Hagler Bailly's most significant  expenses are project  personnel
costs, which consist of consultant  salaries and benefits  (including  bonuses),
and  travel-related  direct project  expenses.  Project  personnel are typically
full-time  professionals employed by Hagler Bailly, although Hagler Bailly often
supplements its professional project staff through the use of subcontractors and
independent  consultants,  predominantly  for public sector work.  Hagler Bailly
believes  that  retaining   subcontractors  and  independent  consultants  on  a
per-engagement  basis provides it with greater  flexibility  and reduced risk in
adjusting  professional  staff  levels in  response to changes in demand for its
services.

Management Buy-Out

     From 1984 to May 1995,  when the management of Hagler Bailly  completed the
Management  Buy-Out,  Hagler  Bailly was a  wholly-owned  subsidiary of RCG. The
results of  operations  since May 25,  1995 have been  affected by a increase in
overhead as a result of becoming an independent  corporation  and an increase in
interest  expense  relating  to  indebtedness  incurred in  connection  with the
Management  Buy-Out.  In  addition,  results  of  operations  of  Hagler  Bailly
subsequent  thereto have been  affected by the  amortization  of $9.0 million of
certain intangibles,  including goodwill, which were recorded in connection with
the Management  Buy-Out.  The data for 1995 in the period to period  discussions
below reflects the results of operations of Hagler Bailly for the period May 26,
1995 through December 31, 1995, and the restatement for the pooling-of-interests
as described below, under "-- Recent Acquisitions."

Compensation Charges

     Prior to December  31,  1996,  the Stock  Option  Plan was  formula  based,
pursuant to which the  exercise  prices of options  granted  were based upon the
book value per share as of May 26, 1995, adjusted for accretion of formula value
during any interim period up to the grant date.  Effective at December 31, 1996,
Hagler  Bailly  adopted an amendment to its Stock Option Plan which  changed the
exercise price of future options to be granted thereunder to the market value of
the   underlying   common   stock.   In  addition,   in   connection   with  the
reclassification  of its common stock,  Hagler Bailly  substituted 0.9 shares of
Class A common stock for each share of Class B common stock  underlying  971,963
options  vesting  on January 1,  1997.  At the same  time,  options to  purchase
971,963  shares  of Class B common  stock  vesting  on  January  1,  1998,  were
canceled. As a result,  Hagler Bailly recorded a non-recurring,  non-cash charge
to  operations  of $6.2  million in December  1996 of which $4.6 million was for
options to purchase  common  stock and $1.6  million  was for 394,160  shares of
common  stock  sold to  employees  during  1996.  These  charges  represent  the
aggregate  difference between the exercise price of such outstanding  options or
the issuance  price of common stock sold to employees  during 1996,  as the case
may be,  and the  appraised  market  value  of the  underlying  common  stock at
December 31, 1996.

Recent Acquisitions

     On December 1, 1997,  Hagler  Bailly  completed the  acquisition  of Apogee
Research,  Inc.  ("Apogee"),  which became a  wholly-owned  subsidiary of Hagler
Bailly.  Apogee is a consulting firm  specializing in the economic and financial
analysis  of  infrastructure,   including  all  aspects  of  transportation  and
environment.  Total  consideration  for the acquisition was  approximately  $8.3
million,  in the form of an aggregate of 409,985  shares of Hagler Bailly common
stock.  The  acquisition  was  accounted  for  as a  pooling-of-interests  under
generally accepted  accounting  principles.  On February 23, 1998, Hagler Bailly
completed the  acquisition  of TB&A and its  wholly-owned  subsidiary,  Theodore
Barry &  Associates.  TB&A,  which became a  wholly-owned  subsidiary  of Hagler
Bailly, is a management  consulting firm to electric,  gas and telecommunication
companies.  Total  consideration  for the  acquisition was  approximately  $10.9
million in the form of an aggregate of 454,994  shares of Hagler  Bailly  common
stock.  The business  combination  was accounted for as a  pooling-of-interests.
Hagler  Bailly's  financial   statements  have  been  restated  to  reflect  the
acquisitions of Apogee and TB&A on a historical  basis. In connection with these
and other  transactions,  Hagler Bailly incurred  business  combination  related
costs of approximately $1.2 million in 1997.

</TABLE>

     Three Months Ended March 31, 1998  Compared to Three Months Ended 
     March 31, 1997

     Revenues.  Revenues  increased  11.9% to $23.6  million in the three months
ended  March 31,  1998 from $21.1  million in the three  months  ended March 31,
1997.  Consulting  revenues  increased 6.9% to $22.3 million in the three months
ended March 31, 1998 compared to $20.9 million in the comparable  period in 1997
primarily  due to increased  client  demand and  increased  capacity from Hagler
Bailly's recent  acquisitions.  However,  overall growth rate was constrained by
management's focus on merger and acquisition-related activities and the strategy
of   deploying   core-consulting   staff  to  create  and   initiate   sales  of
information-based products and services.

     Cost of Services. Cost of services increased 15.0% to $18.8 million for the
three months ended March 31, 1998 from $16.3  million for the three months ended
March 31, 1997. Cost of services generally  increased in proportion to the 11.9%
increase in revenue.  This increase is also  attributable to the increased costs
associated  with the overall  decrease in utilization  rates due to management's
focus on mergers and  acquisitions,  the  marketing  of software  products,  and
increased  staffing  of  high-level  consultants  in  anticipation  of  business
development in the private sector.

     Gross  Profit.  Gross profit  increased  1.5% to $4.9 million for the three
months  ended March 31, 1998 from $4.8  million for the three months ended March
31, 1997 due to the increased revenue.  Gross profit as a percentage of revenues
was 20.7% for the first  three  months of 1998 as compared to 22.8% in the first
three months of 1997,  which is the result of the relative  increase in costs of
services  mentioned above and the deployment of core consulting  staff mentioned
above.

     Selling,  General  and  Administrative   Expenses.   Selling,  general  and
administrative  expenses (which excluded merger related costs) decreased to $1.9
million for the three months  ended March 31, 1998  compared to $2.5 million for
the three months ended March 31, 1997,  due primarily to the  preparation of and
management focus on the IPO occurring in 1997 and the delay of planned marketing
efforts in 1998.

<PAGE>


     Income from  Operations.  Income from  operations  was $2.6 million for the
three months ended March 31, 1998  compared to $2.2 million for the three months
ended March 31, 1997.  This increase in income from  operations is primarily due
to the decrease in selling, general and administrative expenses detailed above.

     Other Income (Expense),  Net. Other income (expense), net was $0.03 million
income for the three months  ended March 31, 1998 and $0.3  million  expense for
the three  months  ended March 31,  1997.  The net change is due to the interest
income  earned  from the  investment  of IPO funds and the  reduction  of Hagler
Bailly's debt.

     Income Tax  Expense.  Income tax  expense  was $1.0  million  for the three
months ended March 31, 1998  compared to $0.8 million for the three months ended
March 31, 1997.  For the three months ended March 31, 1998 and 1997,  income tax
expense as a percentage of income before income tax expense was 39.0%.

     Net Income.  Net income for the three  months ended March 31, 1998 was $1.6
million  compared to $1.2 million for the three months ended March 31, 1997. Net
income as a percentage of revenues increased to 6.8% from 5.6% or 21.4% over the
same period in the prior year.

     1997 Compared to 1996

     Revenues. Hagler Bailly's revenues increased 29.0% to $96.1 million in 1997
from  $74.5  million  in 1996.  A  significant  cause of this  increase  was the
increased  demand  for  management   consulting  services  associated  with  the
restructuring  and  deregulation  of the  electric  and gas sectors  outside the
United States. Consulting revenues increased 28.0% to $94.8 million in 1997 from
$74.0 million in 1996 due primarily to significant growth in consulting revenues
for existing institutional clients.

     Cost of Services. Cost of services increased 21.3% to $71.9 million in 1997
from $59.3  million in 1996.  Hagler Bailly  attributes  the increase in cost of
services to the proportional  increase in revenue and the increase in the number
of in-house professional staff and related other direct costs.

     Gross Profit.  Gross profit  increased  59.1% to $24.2 million in 1997 from
$15.2  million in 1996.  Gross profit as a percentage  of revenues  increased to
25.2%  in 1997  from  20.4% in  1996.  The  improvement  in the  margins  is due
primarily  to higher  growth in  institutional  client  revenues and a continued
increase in higher margin private revenues.

     Selling,  General  and  Administrative   Expenses.   Selling,  general  and
administrative  expenses  increased  33.5% to $13.9  million  in 1997 from $10.4
million in 1996. This increase is primarily attributable to merger related costs
of $1.2 million with the remainder due to the relative  increase in revenues and
management's  strategy of deploying core consulting staff to create and initiate
sales of information-based products and services.

     Income (Loss) from Operations. Income from operations was $10.2 million for
1997  compared to a loss of $1.4  million for 1996.  The increase in income from
operation in 1997 is due primarily to the increased margins mentioned above. The
loss from operations in 1996 is primarily attributable to the approximately $6.7
million  non-recurring,  non-cash stock and stock option compensation charge and
that portion of officer  compensation  that exceeded the compensation that would
have been paid had the  compensation  plan  adopted on January  17, 1997 been in
effect for all of 1996.

     Other Income (Expense),  Net. Other income (expense), net decreased to $0.1
million  expense for 1997 due to the interest  income  earned from  reduction of
debt and the investment of IPO funds  compared to $1.1 million  expense for 1996
attributable to the interest  expense related to the debt incurred in connection
with the Management Buy-Out.


                                      -47-
<PAGE>


     Income Tax Expense.  Income tax expense was $4.7 million,  or 46% of income
before tax expense,  in 1997 compared to $1.0 million, or 38% of loss before tax
expense, in 1996.

     Extraordinary  Gain.  Extraordinary  gain was $2.3 million in 1997 and $0.1
million in 1996.  These gains were primarily due to settlements of notes payable
at more  favorable  terms to Hagler  Bailly and consisted of  significant  notes
payable to a financial  institution in 1997 and several smaller notes payable to
related parties, primarily employees and directors, in 1997 and 1996.

     Net Income (Loss).  As a result of the  preceding,  net income for 1997 was
$7.8 million, compared to a $3.3 million loss for 1996, (excluding the one-time,
non-cash,  compensatory  item  of  $6.2  million  for  stock  and  stock  option
compensation net income for 1996 was $2.8 million).

     1996 Compared to 1995

     Revenues.  Hagler Bailly's revenues increased to $74.5 million in 1996 from
$44.7 million in 1995 ($64.6 million adjusting for months reported).  Consulting
revenues  increased to $74.0  million in 1996 from $44.5  million in 1995 ($55.5
million  adjusting  for  months  reported).   These  revenue  increases  can  be
attributed  principally to the difference in months  reported,  strong growth in
consulting  to the U.S.  utility  sector and the  introduction  of  several  new
corporate strategy consulting services.

     Cost of  Services.  Cost of services  increased  by $ 22.8  million in 1996
compared with 1995. The increase is primarily due to corresponding  increases in
revenues.  Cost of services  decreased in relation to total revenues to 79.6% of
total  revenues  in 1996  from  81.6% of total  revenues  in 1995 due to  higher
margins.  Of this  amount,  $0.5  million  represents  that  portion  of officer
compensation  that exceeded the  compensation  that would have been paid had the
compensation plan adopted in January 1997 been in place for all of 1996.

     Gross  Profit.  Gross profit  increased to $15.2  million in 1996 from $8.2
million in 1995. Gross profit as a percentage of revenues  increased to 20.4% in
1996 from 18.4% in 1995. This can be principally attributed to the difference in
months  reported and an increase in  consulting to the U.S.  utility  sector and
increased  utilization  rates  resulting,   in  part,  from  productivity  gains
associated with technology improvements.

     Selling,  General  and  Administrative   Expenses.   Selling,  general  and
administrative  expenses increased to $10.4 million in 1996 from $5.9 million in
1995. As a percentage of revenues,  selling, general and administrative expenses
increased to 13.9% in 1996 from 13.1% in 1995.  This  increase was due primarily
to the  difference in months  reported and increases in certain  overhead  costs
associated with the Management Buy-Out, increases in loss reserves and increases
in proposal development expenses.

     Income (Loss) from  Operations.  Loss from  operations  was $1.4 million in
1996 compared to income from  operations of $2.4 million in 1995.  The loss from
operations in 1996 is primarily  attributable to the $6.7 million non-recurring,
non-cash stock and stock option  compensation charge and that portion of officer
compensation  that exceeded the  compensation  that would have been paid had the
compensation  plan  adopted on January  17, 1997 been in effect for all of 1996.
These expenses  negatively  impacted  income from  operations by $6.2 million in
1996.  Excluding the foregoing,  income from operations for 1996 would have been
approximately  $4.8 million,  a 100.9%  increase from 1995,  and would have been
6.4% of revenues  in 1996,  as compared  to 5.3% in 1995.  Such  improvement  is
primarily  attributable  to the  difference  in months  reported  and  increased
revenues  and the  decrease in the cost of services  (as a  percentage  of total
revenues), partially offset by the selling, general and administrative expenses.

     Other Income (Expense),  Net. Other income (expense),  net was $1.1 million
expense in 1996  compared  to $0.9  million  expense for 1995.  The  increase is
attributable  to a full  year of  interest  


                                      -48-
<PAGE>


expense in 1996,  related to debt  incurred in  connection  with the  Management
Buy-Out  versus  seven months of interest  expense in 1995.  The debt was repaid
with the proceeds from the IPO.

     Income Tax Expense.  The Management  Buy-Out in 1995 provided Hagler Bailly
with the  opportunity  to make a tax  election  to be  treated  as a cash  basis
taxpayer. For financial reporting purposes,  Hagler Bailly recognizes income tax
expense on an accrual basis. The difference between cash basis and accrual basis
created a deferred income tax liability which represents a temporary difference.
Income tax expense was $1.0 million for 1996  compared to $0.9 for 1995.  Hagler
Bailly incurred income tax expense in 1996 even with an operating loss because a
portion of the stock and stock option compensation charge was not deductible for
tax purposes.

     Extraordinary  Gain.  Extraordinary  gain was $0.1 million in 1996 and $0.8
million in 1995.  These  gains were  primarily  due to the  settlement  of notes
payable at more favorable  terms to Hagler Bailly and consisted of notes payable
to related  parties,  primarily  employees  and  directors.  The 1996 gains were
substantially lower due to the timing of the settlements.

     Net Income (Loss). As a result of the preceding,  net loss was $3.3 million
in 1996 as compared to net income of $1.5 million in 1995, primarily as a result
of the non-recurring stock and stock option compensation charge discussed above.
Net income  (loss) as a percentage of revenues was 4.5% loss in 1996 as compared
to 3.3% income in 1995.  Excluding  expenses  related to: (i) the excess officer
compensation  described  above;  (ii) the interest  expense  described above and
(iii) the  non-recurring,  non-cash  compensation  charge  described  above, net
income  would have been  approximately  $2.8  million  with  income tax  expense
calculated at a combined federal and state income tax rate of 38.3%.

Liquidity and Capital Resources

     In July 1997,  Hagler Bailly  completed an IPO of its common  stock,  which
raised net proceeds of $30.3 million,  $12.5 million of which were used to repay
borrowings from RCG and under Hagler Bailly's credit facility. Prior to the IPO,
Hagler Bailly's primary source of liquidity has been cash flows from operations,
periodically  supplemented by borrowings under a bank line of credit. During the
year, ended December 31, 1997,  Hagler Bailly,  through two of its subsidiaries,
established  a new $15 million  revolving  credit  facility and began  borrowing
under the facility. All such borrowings were repaid at year-end.

     At  December  31,  1996 and 1997,  and March 31,  1998,  Hagler  Bailly had
working capital of $2.4 million, $30.7 million and $34.4 million,  respectively.
Working  capital at March 31, 1998  represents  an increase of $3.7 million from
December  31,  1997.  The  increase  during  the first  three  months of 1998 is
primarily due to the change in accounts  receivable  partially offset by the use
of the  net  proceeds  received  from  the IPO of  common  stock,  the  internal
financing of Hagler Bailly's continued growth and increased internal investments
in product development and infrastructure.  Working capital at December 31, 1997
represents an increase of $28.4 million from December 31, 1996.  The increase in
1997 is primarily  due to net proceeds  received  from the IPO. The increase was
partially  offset by  purchases of property and  equipment,  and merger  related
costs.

     Net cash used in operations  consists primarily of net income plus elements
of cash flows  related to accounts  receivable  and related  billings,  accounts
payable  and  accrued   compensation   adjusted  for  non-cash  items  including
depreciation and provision for possible  losses.  The use of funds in operations
of $7.1 million for the three-month period ended March 31, 1998 can primarily be
attributed  to the  payment of bonuses,  the  funding of the profit  sharing and
401(K) matching plans, and the growth in accounts  receivable.  The use of funds
by  operations  of $5.7  million  for the year ended  December  31,  1997 can be
attributed to the growth in accounts  receivable due to increased  sales volume,
increased tax payments due to the change from cash basis to accrual  basis,  and
other changes in Hagler Bailly's working capital.  Operating activities provided
$3.3 million of Hagler  Bailly's cash  resources for the year ended December 31,
1996,  compared to $1.8  million in the year ended  December  31,  1995.  Hagler
Bailly realized a cash flow benefit from deferred federal and state 


                                      -49-
<PAGE>


income taxes for the two years ended December 31, 1996 and 1995.  Since the IPO,
Hagler  Bailly  was  required  to change  from the cash  method  of  income  tax
reporting  to the accrual  method  which  resulted  in a  recapture  of deferred
federal and state income taxes in 1996 and 1995.

     Investment  activities  provided Hagler Bailly with $3.8 million and ($0.9)
million for the three-month periods ended March 31, 1998 and 1997, respectively.
Investment  expenditures  for the  three-month  period ended 1998 have primarily
been the use of the IPO proceeds to fund the increase in working  capital needs,
merger  and  acquisition  related  activities,  software  development,   capital
expenditures  for information  technology and other resources  necessary for the
growth of the Company.

     Hagler  Bailly  used $11.3  million,  $1.1  million  and $12.6  million for
investing  activities  for the years ended  December  31,  1997,  1996 and 1995,
respectively.  The Management  Buy-Out used $11.8 million of cash from investing
activities in 1995.  Investment  activities for the year ended December 31, 1997
have primarily been capital  expenditures  for information  technology and other
resources necessary for growth of Hagler Bailly.

     Financing  activities  provided  $2.5  million  and  $1.4  million  for the
three-month periods ended March 31, 1998 and 1997, respectively.  The funds were
provided  primarily  through the use of the Company's credit facility.  Net cash
provided by financing  activities of $18.9  million for the year ended  December
31, 1997 was principally  the result of the proceeds  received from the issuance
of  common  stock  in  connection  with  the IPO.  Net  cash  used by  financing
activities for the year ended December 31, 1996 of $1.1 million was  principally
the result of payment of long term debt. During 1995, cash provided by financing
activities of $11.0 million was primarily  attributable to the issuance of stock
and the debt incurred in conjunction with the Management Buy-Out.

     Hagler Bailly  believes the net proceeds from its IPO,  together with funds
generated by  operations  and funds  provided  under the credit  facility,  will
provide  adequate  cash to fund its  anticipated  cash needs,  which may include
future  acquisitions  of  complementary  businesses,  for at  least  the next 12
months.  Hagler  Bailly,  depending on market  conditions,  may  consider  other
sources of financing,  including  equity  financing.  Pending such uses, the net
proceeds  are  invested  in  short-term,   interest-bearing   investment   grade
securities.  Hagler Bailly currently  anticipates that it will retain all of its
earnings for  development  of Hagler  Bailly's  business and does not anticipate
paying any cash dividends in the foreseeable future.

New Accounting Pronouncements

     In June 1997, the Financial  Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130 "Reporting  Comprehensive  Income" ("SFAS
130") and Statement of Financial Accounting Standards No. 131 "Disclosures about
Segments  of an  Enterprise  and Related  Information"  ("SFAS  131").  SFAS 130
establishes  standards for reporting  comprehensive income and its components in
the  consolidated  financial  statements.  SFAS 131  establishes  standards  for
reporting  information  on  operating  segments in interim and annual  financial
statements.  SFAS 130 and  SFAS 131 will  become  effective  for  Hagler  Bailly
beginning in 1998.  SFAS 130 and SFAS 131 require  disclosure  only and will not
have a material impact on Hagler Bailly's  consolidated  financial  position and
results of operations.

Year 2000

     Hagler Bailly relies on software technology to deliver its services and has
taken actions to evaluate the nature and extent of the work required to make its
systems and  infrastructure  "Year 2000"  compliant.  Hagler  Bailly  management
believes  that the costs  associated  with the Year 2000 issue should not have a
material  adverse  effect on the results of operations or financial  position of
Hagler Bailly in future periods.  However,  despite Hagler  Bailly's  efforts to
address the Year 2000  impacts on its  internal  systems,  Hagler  Bailly is not
certain  that it has fully  identified  all such  impacts or that it can resolve
them  without  disruption  of its  business  and without 


                                      -50-
<PAGE>


incurring  significant  expenses.  In addition,  even if the internal systems of
Hagler Bailly are not materially  affected by the Year 2000 issue, Hagler Bailly
could be affected as a result of any  disruption in the operation of the various
third-party enterprises with which Hagler Bailly interacts.

Recent Events

     On June 30, 1998,  Hagler Bailly  acquired all of the stock of Izsak Grapin
et Associes SARL, a French limited  liability  company that provides  management
consulting services to corporate clients,  for approximately $5.0 million,  paid
in 183,550 shares of Hagler Bailly common stock. The acquisition is non-material
and is intended to be  accounted  for under the  pooling-of-interests  method of
accounting.

     On June 11, 1998,  Hagler  Bailly,  Inc.  entered  into an exclusive  joint
venture  with  Cap  Gemini  America,  Inc.  to  deliver  information  technology
consulting  services and solutions to electric,  gas and water  utilities in the
United States and Canada. The joint venture, Cap Gemini Hagler Bailly L.L.C., is
owned equally by the two companies.  On June 16, 1998, Cap Gemini purchased from
Hagler  Bailly   470,975   shares  of  Hagler  Bailly  common  stock  for  total
consideration of $12,455,876.

appropriate solutions, implementation, financing and on-going management. Hagler
Bailly's  services  are  designed to provide  tangible  value to  clients.  This

          Strategy practice.

provide  clients the full range of services and  capabilities  of Hagler Bailly.
From  an  operational  standpoint,  Hagler  Bailly  regularly  reviews  and,  as
appropriate,  restructures  these  practice  areas and  services  to address the
changing  business  problems,  strategic  alternatives  and policy issues of its
public and private clients.

Marketing and Sales

     Hagler  Bailly's client  development  activities are a mixture of marketing
efforts,  client acquisition  techniques and the development of repeat business.
Marketing   efforts  are  accomplished   through  brand  development  and  brand
management. Hagler Bailly maintains and enhances its name and reputation through
speeches,  presentations,  articles in industry,  business,  economic, legal and
scientific journals, and through other publications and press releases.

     Hagler  Bailly  establishes  a  client  development  goal  for  each of its
consulting  officers and principals and  systematically  reviews  individual and
group  performance  against these goals.  Hagler Bailly's  compensation  system,
particularly  in the award of bonuses and stock  options,  is  weighted  towards
success in meeting these client development goals.

     o    Private Sector. In the private sector,  client acquisition  techniques
          include  referrals and focused  presentations  to boards of directors,
          chief  executive  and  operating  officers  and  other  executives  of
          prospective  client  companies.   Presentations   generally  focus  on
          opportunities  in the market segments most relevant to the prospective
          clients,   examples  of  Hagler  Bailly's  previous  work  in  related
          industries and Hagler Bailly's international capabilities.

     o    Public Sector.  In the public sector,  contracts are awarded primarily
          on the basis of competitive solicitation.  Hagler Bailly has developed
          strong  capabilities  to  prepare  proposals  that  respond to complex
          requests and often require the  integration  and  coordination  of the
          services of several subcontractors and independent consultants. Hagler
          Bailly has also developed a detailed  understanding  of government and
          other institutional  procurement  regulations in the United States and
          internationally. In addition, in order to obtain government contracts,
          consultants  must adhere to stringent cost,  accounting and regulatory
          controls.  In order to comply with such  requirements,  Hagler  Bailly
          regularly holds training seminars to ensure compliance with applicable
          government   regulations  and  uses  a  sophisticated   computer-based
          accounting  system  that  allows  it to track  costs in  adherence  to
          government standards.  Hagler Bailly also meets public sector clients'
          cost guidelines through competitive pricing.

Client and Representative Services

     In 1997,  Hagler Bailly performed over 1,360 assignments for 447 clients in
over 22  countries.  Because of the nature and scope of many of Hagler  Bailly's
projects,  Hagler Bailly  derives a  


                                      -53-
<PAGE>


significant  portion of its revenues from a relatively limited number of clients
that operate exclusively in the energy,  telecommunications,  transportation and
environment  sectors.  Revenues from Hagler Bailly's 10 most significant clients
accounted for approximately 51.7%, 61.0% and 50.1% of its revenues for the years
ended  December 31,  1995,  1996 and 1997,  respectively.  In the past 18 years,
Hagler  Bailly  has  grown  from a  single  office  to a  worldwide  network  of
operations with principal  offices in nine cities in the United States and seven
other countries.

Competition

     The   market   for   consulting   services   in  the   fields  of   energy,
telecommunications, transportation and the environment is intensely competitive,
highly  fragmented  and  subject to rapid  change.  The market  includes a large
number of participants from a variety of consulting market segments, both in the
United  States and  internationally,  including  general  management  consulting
firms,  the consulting  practices of accounting  firms,  consulting  engineering
firms,  technical and economic  advisory firms and market research  firms.  Many
information   technology  consulting  firms  also  maintain  significant  energy
practices and others may enter the field in the future.  Many of these companies
are national and  international in scope and have greater  financial,  technical
and marketing resources than Hagler Bailly. In the private sector, Hagler Bailly
believes the key competitive factors are quality and service, followed by price,
while in the public sector Hagler Bailly  believes the key  competitive  factors
are price and service.  Hagler Bailly believes that its experience,  reputation,
industry focus,  and broad range of services have and will continue to enable it
to compete  effectively  in the  private  and public  sector  both in the United
States and internationally.

Employees

     As of March 2, 1998, Hagler Bailly's  personnel  consisted of 418 full-time
employees, including 280 consultants and 138 support personnel, and 59 part-time
employees. The two largest offices of Hagler Bailly are Arlington,  Virginia and
Boulder, Colorado with 155 and 78 full-time employees, respectively. Eighty-nine
full-time  employees  are  stationed  outside  the United  States.  This  number
excludes the personnel of Hagler Bailly's affiliates in Argentina, Indonesia and
Pakistan which have,  respectively,  8, 12 and 28 full-time  employees.  It also
excludes locally hired independent  contractors.  Hagler Bailly  supplements its
full-time  staff  with  outside  consultants  with  proven  experience  in their
respective  fields.   Several  of  these  outside   consultants  are  well-known
professors at leading universities.

     Hagler  Bailly's  36  consulting  officers  average 16 years of  management
consulting  experience,   most  of  which  has  been  in  the  energy,  utility,
transportation  and  environmental  industries.  Several of its most experienced
consultants have worked together for over ten years. Hagler Bailly believes that
this long-term experience of working together as a team enables Hagler Bailly to
respond  quickly to changing  market  conditions and  consistently  deliver high
quality consulting services in response to the complex demands of its clients.

     Hagler  Bailly  believes its success  depends in large part on  attracting,
retaining and motivating  talented,  creative and professional  employees at all
levels.  Hagler Bailly  de-emphasizes  hiring  directly  from graduate  schools,
instead  seeking  graduates  from top  schools  with prior  relevant  consulting
experience and strong project management,  analytic and communications skills in
competitive  and  regulated   industries,   especially   those  with  meaningful
international  experience.  Hagler Bailly also hires  professionals  with senior
executive experience directly from industry.

     Hagler Bailly attracts and motivates its  professional  and  administrative
staff by offering competitive packages of base and incentive  compensation,  and
benefits.  All full-time and part-time staff members are eligible for bonuses. A
significant  percentage of Hagler  Bailly's  income before  bonuses and taxes is
distributed as bonuses to its staff,  the majority of which is targeted  towards
Hagler Bailly's top performers -- usually its consulting  officers,  principals,
and  managers.  The bonus awards are the result of  measurement  of  performance
against predetermined target compensation goals that balance individual and team
performance.  This  structure  gives senior staff  members a 


                                      -54-
<PAGE>


vested interest in Hagler Bailly's  overall success and performance  while still
promoting  individual  initiative and excellence.  Hagler Bailly appreciates the
importance of recognition and a promotion track for its administrative staff and
fully integrates this staff into the conduct of its business. The performance of
all employees is reviewed annually for compensation and promotion purposes.

Properties

     In aggregate,  Hagler Bailly leases  approximately  186,586  square feet of
office  space  in  the  following   principal   offices:   Arlington,   Virginia
(headquarters);  Boston,  Massachusetts;  Boulder, Colorado;  Chicago, Illinois;
Houston, Texas; Los Angeles, California; Madison, Wisconsin; New York, New York;
and San  Francisco,  California.  Hagler  Bailly  also  leases an  aggregate  of
approximately  6,590  square  feet of office  space in the  following  principal
foreign offices: Buenos Aires, Argentina; Dublin, Ireland; Islamabad,  Pakistan;
Jakarta,  Indonesia;  Paris, France; Sao Paulo, Brazil; and Toronto,  Canada. In
addition,  Hagler  Bailly  leases  minimal  space in other  foreign and domestic
cities. Each principal office represents a permanent location servicing multiple
clients which is run by a member of Hagler Bailly's senior management. From time
to time Hagler Bailly leases a project office to enable it to service a specific
international  project involving a particular  individual  client, in which case
the office is paid for  directly  by the client.  Hagler  Bailly  currently  has
project offices in 17 foreign  locations  totaling  approximately  25,696 square
feet.  All  of  Hagler  Bailly's  principal,  branch  and  project  offices  are
electronically  linked  together  and  have  access  to all of  Hagler  Bailly's
capabilities  and  core  consulting  tools.  Hagler  Bailly  believes  that  its
facilities are adequate for its current needs and that additional facilities can
be leased to meet future needs.

Legal Proceedings

     Hagler  Bailly's  indirect  subsidiary,  Theodore Barry & Associates,  is a
defendant  in a lawsuit  brought in the  United  States  District  Court for the
Northern District of Illinois,  Michael A. Laros v. Theodore Barry & Associates,
No.  95-C4175,  by one of its former  executives  seeking payment of a bonus and
salary allegedly due him and payment of principal and interest on a subordinated
note of TB&A held by Mr. Laros, prejudgment interest and costs and fees. TB&A is
defending the suit.  Hagler Bailly does not believe that the  resolution of this
lawsuit will have a material adverse effect on its business, financial condition
or results of operations.

     Apogee, one of Hagler Bailly's  wholly-owned  subsidiaries,  has received a
subpoena  from  the  Office  of  the  Inspector  General  of  the  Environmental
Protection Agency (the "EPA") requesting records from April 1993 through October
1995  pertaining to a contract  between  Apogee and the EPA. The work under this
contract has been  completed.  The subpoena was served in connection with an EPA
investigation relating to the submission of potential false statements and false
claims under the contract.  Hagler Bailly and Apogee are cooperating  fully with
the EPA. At this time Hagler Bailly is unable to determine what effect,  if any,
the investigation will have on its business,  financial  condition or results of
operations.

     Hagler  Bailly  and its  subsidiaries  are  from  time to time  parties  to
litigation arising in the ordinary course of business. Neither Hagler Bailly nor
any of its  subsidiaries is a party to any pending  material  litigation nor are
any of them aware of any  pending  or  threatened  litigation  that would have a
material adverse effect on Hagler Bailly or its business.

(1)  On December 31, 1996,  PHB  liquidated  its wholly owned  subsidiary in the
     U.K.  Of PHB's loss of $662,609 in 1996,  $548,757  represented  cumulative
     foreign currency translation losses which had previously been recorded as a
     separate  component of PHB's  stockholders'  equity. In 1997,  $328,070 was
     recorded  as  management's  estimate  of  the  uncollectable  net  proceeds
     resulting from the liquidation.

(2)  Stock issued or subject to issuance under subscriptions  receivable entered
     into  within 12 months  preceding  the closing of the Merger is presumed to
     have been  issued  in  contemplation  of the  proposed  transaction  and is
     required  to be  accounted  for at its  fair  market  value  on the date of
     issuance.  Accordingly,  PHB has recognized noncash,  nontaxable deductible
     compensation  charges  for the year ended  December  31, 1997 and the three
     months ended March 31, 1998 of  $9,884,800  and  $2,164,800,  respectively,
     representing  the  difference  between the fair value and the book value of
     shares of common stock then issuable.

     compensation paid to senior staff members in excess of a standard bonus set
     for  their  respective  staff  levels.  The  excess  performance  incentive
     compensation  was  included in Cost of services  and  Selling,  general and
     administrative  and was $39,000,  $2,931,000,  $6,260,000,  $9,588,000  and
     $7,294,000  for the years ended  December 31, 1993,  1994,  1995,  1996 and
     1997,  respectively,  and  $1,823,000  for the three months ended March 31,
     1997.  If PHB had not paid the excess  incentive  compensation,  net income
     would  have  been   $376,000,   $1,821,000,   $4,394,000,   $6,217,000  and
     $4,605,000,  for the years ended December 31, 1993,  1994,  1995,  1996 and
     1997,  respectively,  and  $1,472,000  for the three months ended March 31,
     1997, assuming a statutory taxation rate of 41.1%.

                                       PHB
                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS

Overview

     PHB is an international  economic and management consulting firm, providing
its clients with strategic  advice and analysis to support the  development  and
execution of economically sound strategies in business, litigation,  regulatory,
and policy matters. PHB's staff of 185 economists, business experts, accountants
and other  professionals  have  assisted  corporations,  governments  and public
agencies on thousands of client  assignments in a wide range of industries.  PHB
consultants  apply  advanced  analytical  techniques  to  provide  comprehensive
strategic  advice for clients.  PHB advises leaders in business,  government and
the legal profession throughout the world.

     Total  revenues  represent  the  total of all  revenues  related  to client
engagements,    including   revenues   associated   with   professional   staff,
subcontractors,   independent   consultants  and  use  of  computer  technology.
Consulting  revenues  represent the amount of engagement revenue associated with
billings by PHB's professional staff. Subcontractor and other revenues represent
revenues associated with  subcontractors and independent  consultants engaged by
PHB on its  assignments,  as well as  travel  and per  diem  reimbursements  and
computer technology use charges to clients.

     PHB derives  substantially  all of its revenues from fees for  professional
services.  Clients are typically  invoiced on a monthly basis.  The  substantial
majority of fees are billed at standard  hourly  rates.  Revenues  from standard
hourly  rate  engagements  are  recognized  as hours  are  recorded.  Costs  are
recognized as they are incurred.  Revenues from cost-plus  fixed-fee  contracts,
which have not been  material to date,  are  recognized as costs are incurred on
the basis of direct costs plus  allowable  indirect costs and a pro rata portion
of  estimated  fees.  The  remainder  of the  revenues are based on lump sum fee
arrangements.  A loss, if any, on an  engagement  is recognized  when it becomes
known  and  the  amount  of the  loss is  reasonably  determinable.  PHB's  most
significant  expenses  relate to the direct cost of providing  client  services.
These costs consist of consultant  salaries and benefits (including bonuses) and
travel-related  project  expenses.  Project  personnel are  typically  full-time
professionals  employed by PHB,  although PHB often supplements its professional
project staff through the use of subcontractors and independent consultants.

Compensation Charges

     In anticipation  of the Merger,  PHB recognized a  non-recurring,  non-cash
charge to  operations  of $10.0 million and $2.2 million for the 12 months ended
December 31, 1997 and the three months ended March 31, 1998, respectively.  This
charge is required  under  generally  accepted  accounting  principles for stock
issued, or obligated to be issued, during the 12 months preceding the closing of
the  pending  merger  based  on the  presumption  that  such  issuances  were in
contemplation  of the Merger.  The charge  represents  the aggregate  difference
between the book value of PHB common stock sold or  committed  to PHB  employees
during 1997 and 1998 and the appraised market value of the PHB common stock. The
employee  purchases,  or obligations to purchase shares of common stock in 1997,
were part of PHB's long-standing policy of requiring newly promoted senior level
consultants  to purchase a specified  number of shares of PHB common stock based
on their  respective  staff  level.  This policy  provides  PHB with  additional
capitalization  and working  capital.  New senior  level  personnel  joining PHB
during 1997, consistent with its long-standing  practice, were also obligated to
buy a  specified  number  of  shares  based on their  staff  level.  The  shares
purchased or obligated to be purchased by these  employees  are also included in
the 1997  compensation  charge.  During the three  months  ended March 31, 1998,
similar stock purchase obligations arose for which a compensation was recorded.

     The statement of operations  data for the years ended  December 31 includes
performance incentive  compensation paid to senior staff in excess of a standard
bonus set for their  respective staff 


                                      -67-
<PAGE>


level.  The excess  performance  incentive  compensation was included in Cost of
services and Selling,  general and administrative  and was $39,000,  $2,931,000,
$6,260,000,  $9,588,000  and  $7,294,000  for the years ended December 31, 1993,
1994, 1995, 1996 and 1997, respectively.

     Three Months ended March 31, 1998  Compared to Three Months ended 
     March 31, 1997

     Revenues.  Revenues  of PHB  decreased  2.6% to $15.6  million in the three
months  ended March 31, 1998 from $16.0  million in the three months ended March
31, 1997.  The revenue  reduction  related  primarily  to reduced  subcontractor
activity.  Consulting  revenues of PHB  increased  0.6% to $13.5  million in the
three months ended March 31, 1998  compared to $13.4  million in the  comparable
period in 1997.

     Cost of Services.  Cost of services of PHB decreased 18.5% to $10.0 million
for the three  months  ended  March 31,  1998 from $12.3  million  for the three
months ended March 31, 1997. The reduction is primarily due to lower performance
incentive   compensation   for  senior   consulting   staff  working  on  client
engagements.  Also, during the three months ended March 31, 1998,  subcontractor
costs were lower and consulting  labor  resources  were more heavily  applied to
business development activities rather than providing client services.

     Gross Profit.  Gross profit  increased  49.4% to $5.6 million for the three
months  ended March 31, 1998 from $3.7  million for the three months ended March
31, 1997. Gross profit as a percentage of revenues was 35.8% for the first three
months of 1998 as  compared  to 23.4% in the first  three  months of 1997.  This
increase is principally a result of the lower performance incentive compensation
previously mentioned.  Billing rates in 1998 were higher over the previous year.
There  was  virtually  no  gross  profit  impact  related  to the  reduction  in
subcontractor revenues since such revenues carry little or no gross profit.

     Selling,  General and Administrative.  Selling,  general and administrative
expenses  decreased  2.4% to $2.9  million for the three  months ended March 31,
1998  compared to $3.0 million for the three months ended March 31, 1997.  Lower
performance  incentive  compensation  for  executive  staff  accounted  for $0.5
million of the reduction. However, this reduction was substantially offset 


                                      -68-
<PAGE>


since consulting staff devoted more labor resources to developing  proposals and
negotiating new engagements.

     Income from Operations. Income from operations, excluding the effect of the
Compensation in connection with  subscriptions for issuance of common stock, was
up 266% to $2.6 million for the three  months  ended March 31, 1998  compared to
$722,000  for the three months  ended March 31,  1997.  This  increase is due to
lower  performance  incentive  awards  effective  January 1,  1998.  Performance
incentive  compensation  earned by senior  consultants in excess of the standard
target bonus for their level has been  terminated in connection with the pending
merger.

     Other  Income  (Expense),  Net.  Other  income  (expense),  net was $82,000
expense for the three  months  ended March 31, 1998 and $46,000  expense for the
three  months ended March 31, 1997.  The change is  principally  due to slightly
higher foreign exchange losses related to PHB's New Zealand subsidiary in 1998.

     Income Tax  Expense.  Income tax  expense  was $1.0  million  for the three
months  ended March 31, 1998  compared to $321,000  for the three  months  ended
March 31, 1997.  The 1998 expense is higher than the expected  statutory rate of
41.1% due to the  nondeductibility  of the $2.2 million  compensation charge for
tax reporting purposes.  The 1997 tax expense reflects the proportional share of
the total 1997 expense which is higher than the statutory rate of 41.1%.

     Net Income  (Loss).  Net income (loss) for the three months ended March 31,
1998 was  ($656,000)  compared to $355,000  for the three months ended March 31,
1997.  Net  income,   excluding  the  effect  of  the  compensation  charge  for
subscriptions  for the issuance of common stock,  increased to 9.7% from 2.2% in
the prior year as a percentage  of  revenues.  This  increase is  primarily  the
result of the change in performance incentive compensation previously mentioned.
See "--Compensation Charges."

     1997 Compared to 1996

     Revenues. PHB's revenues decreased 7.3% to $62.8 million in 1997 from $67.7
million in 1996.  Consulting  revenues  decreased  1.9% to $52.1 million in 1997
from $53.1  million in 1996.  Consulting  revenues  for PHB's Energy and Network
Industries  practice grew by 41%, reflecting the increased demand for consulting
services  associated  with the  restructuring  and  deregulation of the electric
utility industry.  However,  consulting  revenues for PHB's Litigation  practice
decreased 38%  primarily as a result of declining  revenues  generated  from one
litigation case which  represented  approximately 16% of PHB's total revenues in
1996 and approximately 3% of PHB's total revenues in 1997. Also, PHB reduced its
pricing for computing technology used by its clients due to competitive industry
trends.  This price  reduction  resulted in a $1.3 million  decrease in revenues
between 1997 and 1996.

     Cost of Services.  Cost of services decreased 6.5% to $47.5 million in 1997
from $50.8 million in 1996. The decrease reflects the decrease in total revenues
and the  redeployment  of  consulting  labor  resources to marketing and selling
activities.  Liquidation  of the U.K.  subsidiary  in December 1996 also reduced
PHB's  costs of services in 1997.  Cost of  services  as a  percentage  of total
revenues increased to 75.6% in 1997 from 74.9% in 1996. The percentage  increase
principally  results from the reduction in pricing for computer  technology  use
charged to clients.

     Gross  Profit.  Gross profit  decreased  9.8% to $15.3 million in 1997 from
$17.0  million in 1996.  Gross profit as a percentage  of revenues  decreased to
24.4% in 1997 from 25.1% in 1996. Approximately $1.3 million of this decrease is
a result of the reduction in computer  technology use pricing for PHB's clients.
Adjusting for this  reduction,  gross profit as a percentage of revenues in 1996
would have been 24.0%.

     Selling,  General and Administrative.  Selling,  general and administrative
expenses  decreased  9.2% to $14.2  million in 1997 from $15.6  million in 1996.
Although  more  consulting  labor 


                                      -69-
<PAGE>


was  deployed to marketing  and selling in 1997,  this was offset as a result of
lower out-of-pocket business development expenses.

     Income from Operations. Income from operations,  excluding the compensation
charge of $9.9  million in  connection  with  subscriptions  for the issuance of
common  stock,  was  $798,000  for 1997  compared  to  $681,000  for 1996.  As a
percentage of total  revenues,  income from operations  before the  compensation
charge increased to 1.3% in 1997 from 1.0% in 1996.

     Other Income  (Expense),  Net.  Other income  (expense),  net  increased to
$273,000 in expense for 1997, due principally to a foreign exchange loss related
to the New Zealand  subsidiary,  compared  to  $286,000 in income in 1996,  as a
result of a foreign exchange gain related to the U.K. subsidiary.

     Income Tax Expense.  The 1997 provision for tax is higher than the expected
statutory rate of 41.1% due to the  nondeductibility  for tax reporting purposes
of the compensation  charge in connection with subscriptions for the issuance of
common stock and also due to a loss provision on an equity investment in an U.K.
affiliate for which an ordinary income deduction is not available.

     Net Income (Loss).  Net income (loss),  excluding the compensation  charge,
for 1997 was ($82,000) compared to $303,000 for 1996.  Excluding the performance
incentive  compensation  in excess of standard  target  bonuses and the non-cash
compensation  charges,  net income for 1997 would have been  approximately  $4.6
million based on a combined  federal and state income tax of 41.1%,  compared to
$6.2 million in 1996. See "--Compensation Charges."

     1996 Compared to 1995

     Revenues.  PHB's  revenues  increased  19.7% to $67.7  million in 1996 from
$56.6 million in 1995.  Consulting  revenues increased 16.5% to $53.1 million in
1996 from $45.6 million in 1995.  Consulting revenues for the Energy and Network
Industries  and  Litigation  practices  grew 13% and 21%,  respectively,  as PHB
continued to  participate  in the growth of  consulting  services to the utility
industry.  The environmental  sector of PHB's Litigation  practice increased 28%
over 1995,  primarily due to increased work for insurance  companies.  There was
further  growth in the Litigation  practice due to a significant  pharmaceutical
case.  Other revenue  increased $1.0 million as a result of billing  clients for
computer technology usage.

     Cost of  Services.  Cost of  services  increased  by $8.7  million  in 1996
compared to 1995. The increase reflects the increase in total revenues.  Cost of
services  increased as a  percentage  of revenues to 74.9% in 1996 from 74.3% in
1995  primarily  due to  proportionally  higher  subcontractor  activity in 1996
compared to 1995.

     Gross Profit.  Gross profit  increased  16.9% to $17.0 million in 1996 from
$14.5  million in 1995.  The  increase  is  primarily  the  result of  increased
computer  technology  revenues  billed to  clients  in 1996.  Gross  profit as a
percentage of total revenues decreased to 25.1% in 1996 from 25.7% in 1995.

     Selling,  General and Administrative.  Selling,  general and administrative
expenses  increased  16.7% to $15.6  million in 1996 from $13.4 million in 1995.
Commensurate  with the volume  increase  in PHB's  revenues,  this  increase  is
primarily a result of an increase in business  development  activity in 1996 and
an  increase  in the  provision  for  doubtful  accounts  related  to the higher
business volume.

     Income from Operations.  Income from operations decreased 39.3% to $681,000
in 1996  compared  to Income  from  operations  of $1.1  million  in 1995.  This
decrease  is  due  principally  to a  $663,000  charge  recognized  in  1996  in
connection with the liquidation of PHB's U.K. subsidiary.



                                      -70-
<PAGE>


     Other Income (Expense),  Net. Other income (expense), net increased 264% to
$286,000 in income in 1996 compared to $78,000 in income for 1995,  primarily as
a result of PHB's foreign exchange gain in 1996 related to the U.K. subsidiary.

     Income Tax  Expense.  The  effective  income tax rate of 68.6% for 1996 was
substantially  higher than the expected statutory rate of 41.1% due to the level
of permanent differences related to unallowable deductions. The effective income
rate of 47.9% for 1995 was slightly  higher than the statutory  rate due to less
nondeductible  permanent  differences  principally related to travel, meals, and
entertainment expenses.

     Net Income (Loss).  Excluding the performance incentive compensation charge
in excess of standard target  bonuses,  net income for 1996 would have been $6.2
million compared to $4.4 million in 1995. See "--Compensation Charges."

Liquidity and Capital Resources

     PHB's  primary  source of liquidity has been and is expected to continue to
be cash flow from  operations,  periodically  supplemented by borrowings under a
bank line of credit.  PHB  maintains a revolving  line of credit of $4.0 million
with a bank. At March 31, 1998, borrowings outstanding under this line of credit
were  $550,000  at an  interest  rate of prime  plus  0.5%.  At March 31,  1998,
December  31,  1997 and  December  31,  1996,  PHB had  working  capital of $7.4
million,  $4.9 million and $4.7 million,  respectively.  The increase in working
capital reflects increases in the cash position of PHB primarily due to accounts
receivable collections and from increases in receivables and unbilled services.

     PHB had net cash provided by operations of $2.1 million for the three-month
period  ended March 31,  1998 which  consisted  primarily  of net income of $1.5
million,  excluding the compensation charge for subscriptions in connection with
the issuance of common stock,  and deferred  income taxes of $1.1 million.  This
was offset in part by cash flows  related to accounts  receivable  and  unbilled
services.  Net cash  provided by operations  were  $393,000,  $5.7 million,  and
$679,000 for the years ended December 31, 1997, 1996 and 1995, respectively. The
year  over  year  differences  are  primarily  due to the  changes  in  accounts
receivable and unbilled  services which was a source of cash in 1996 but not the
other years.

     Investment activities resulted in cash flows of ($228,000) and $698,000 for
the three-month periods ended March 31, 1998 and 1997, respectively. Investments
for the  three-month  period ended March 31, 1998 were primarily to fund capital
expenditures for information technology.  In 1997, proceeds from the collections
of receivables  were received in connection  with the  liquidation of PHB's U.K.
subsidiary.   PHB  used  $766,000,  $3.3  million  and  $735,000  for  investing
activities for the years ended December 31, 1997,  1996 and 1995,  respectively.
Investment  activities  have  primarily  related  to  capital  expenditures  for
information  technology  although in 1996  approximately $2.2 million was due in
connection  with the  liquidation of the U.K.  subsidiary  ($1.7 million of this
amount was received in 1997).

     Financing activities used $960,000 and $822,000 for the three-month periods
ended  March 31,  1998 and 1997,  respectively.  The funds were used to pay down
short term borrowings  outstanding at the respective prior year-end periods. Net
cash provided by financing  activities  of $234,000 for the year ended  December
31, 1997 was principally  the result of stock  purchased by senior  consultants.
Net cash used by financing  activities  for the year ended December 31, 1996 was
$1.5 million  principally  due to repayment of borrowing  under the bank line of
credit.  During 1995, net cash provided by financing  activities of $206,000 was
primarily  attributable to short term bank borrowings offset by the reduction in
capital lease obligations.

     PHB  believes  that  current   projected  levels  of  cash  flows  and  the
availability of financing,  including  borrowings  under PHB's credit  facility,
will be adequate to fund its  operations  throughout  the period  preceding  the
Merger.

New Accounting Pronouncements

     In June 1997, the Financial  Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, "Reporting  Comprehensive Income" ("SFAS
130"),  and Statement of Financial  Accounting  Standards  No. 131  "Disclosures
about Segments of an Enterprise and Related  Information" ("SFAS 131"). SFAS 130
establishes  standards for reporting  comprehensive income and its components in
the  consolidated  financial  statements.  SFAS 131  establishes  standards  for
reporting  information  on  operating  segments in interim and annual  financial
statements.  SFAS 130 and SFAS 131 will become  effective  for PHB  beginning in
1998.  SFAS 130 and SFAS 131 require  disclosure only and will have no impact on
PHB's consolidated financial position and results of operations.

Year 2000

     PHB relies on software technology to deliver its services. PHB is currently
in the process of evaluating the potential  impact of the Year 2000 issue on its
business  and the  related  expenses  that  would  foreseeably  be  incurred  in
attempting  to remedy  such impact  (including  testing  and  implementation  of
remedial  action).  Management  believes that the costs associated with the Year
2000  issue  should  not  have a  material  adverse  effect  on the  results  of
operations  or financial  position of PHB in future  periods.  However,  despite
PHB's efforts to address the Year 2000 impacts on its internal  systems,  PHB is
not certain that it has fully identified all such impacts or that it can resolve
them  without  disruption  of its  business  and without  incurring  significant
expenses.  In addition,  even if the internal  systems of PHB are not materially
affected  by the Year  2000  issue,  PHB  could be  affected  as a result of any
disruption in the operation of the various  third-party  enterprises  with which
PHB interacts.

     As a group,  PHB's  domestic  senior  staff  members have broad yet diverse
experience. PHB has consultants who specialize in energy, environment, regulated
industry,  litigation and  telecommunications.  In its overseas  offices,  PHB's
consultants  tend to specialize in the Energy and Network  Industries  practice.
The  dynamic  synergy  between  its  offices  enables  PHB to offer its  clients
multi-office project teams, ideally suited to the needs of each project.

     PHB maintains its high caliber of staff by  challenging  each  individual's
creativity and by offering competitive  compensation  packages,  which include a
bonus  and  profit-sharing  plan and  generous  medical  benefits.  Bonuses  and
promotions  are awarded based on personal  performance in reaching and exceeding
targets,  and those targets are determined based on level of experience and each
individual's past performance.  As they gain experience,  employees  progress to
increasing  levels  of  project   conceptualization,   management,   and  client
relationships.

electronically  connected  and have e-mail and file transfer  capabilities.  PHB
continually upgrades its systems to meet project and staff needs.

Legal Proceedings

     Although PHB is  occasionally  a party to litigation  arising in the normal
course of business, the firm is neither party to any pending material litigation
nor aware of any  pending or  threatened  litigation  that would have a material
adverse effect on PHB or its business.

                 DESCRIPTION OF HAGLER BAILLY CAPITAL STOCK AND
                        COMPARISON OF STOCKHOLDER RIGHTS

Hagler Bailly Capital Stock

     Hagler  Bailly's  Certificate  of  Incorporation  authorizes two classes of
capital stock:  common and  preferred.  The terms of these classes are described
below.

Common Stock

     Hagler Bailly is authorized  currently to issue 20,000,000 shares of Hagler
Bailly  common stock and will be authorized  to issue  50,000,000  shares if the
Certificate  Amendment  is  approved.  As of  the  Hagler  Bailly  record  date,
9,627,503  shares of Hagler Bailly common stock were issued and  outstanding and
Hagler Bailly had outstanding  stock options granted to directors,  officers and
other employees for 2,039,736  shares of Hagler Bailly common stock.  Each share
of Hagler Bailly  common stock has the same relative  rights and is identical in
all respects to each other share of Hagler Bailly common stock.

     Holders of Hagler Bailly common stock are entitled to one vote per share on
each matter  properly  submitted to stockholders  for their vote,  including the
election of  directors.  Holders of Hagler  Bailly  common stock do not have the
right to cumulate  their votes for the election of  directors,  and they have no
preemptive or  conversion  rights with respect to any shares that may be issued.
Hagler Bailly common stock is not subject to additional  calls or assessments by
Hagler  Bailly,   and  all  shares  of  Hagler  Bailly  common  stock  currently
outstanding are fully paid and non-assessable.

     Holders of Hagler  Bailly  common stock are  entitled to receive  dividends
when and as  declared  by the Board of  Directors  of Hagler  Bailly  out of any
assets  legally  available  for   distribution.   No  such  dividends  or  other
distributions may be declared or paid, however, unless all accumulated dividends
and any sinking fund,  retirement  fund or other  retirement  payments have been
satisfied on classes of stock having  preference as to such payments over common
stock.  In the unlikely event of any  liquidation,  dissolution or winding up of
Hagler Bailly, assets of Hagler Bailly would be distributed, in cash or in kind,
to the holders of Hagler Bailly common stock, but only after satisfaction of all
debts and other liquidation preferences of Hagler Bailly.

Preferred Stock

     Hagler  Bailly's  Certificate  of  Incorporation  authorizes  its  Board of
Directors, without further stockholder approval, to issue up to 5,000,000 shares
of preferred stock for any proper corporate purpose.  The Board of Directors has
broad authority to determine the rights and preferences of the preferred  stock,
which may be issued in one or more  series.  These  rights and  preferences  may
include voting,  dividend,  conversion and liquidation rights that may be senior
to the Hagler Bailly common stock.  The Hagler Bailly Board of Directors has not
authorized  any classes of preferred  stock.  The  issuance of preferred  shares
having  special  rights or  preferences  could  have the effect of  delaying  or
preventing a change in control of Hagler Bailly even if such a change in control
would be in the best interest of the holders of Hagler Bailly common stock.

Comparison of Stockholder Rights

     If the Merger is  consummated,  the holders of PHB common stock will become
holders of Hagler Bailly common stock. As a result,  Hagler Bailly's Certificate
of  Incorporation  and  Bylaws,  and  the  applicable   provisions  of  Delaware
Corporation  Law, will govern the rights of current holders of PHB common stock.
The following is a comparison of the rights of holders of common stock of Hagler
Bailly and PHB based on the terms of the  governing  documents of Hagler  Bailly
and  PHB,  Delaware  Corporation  Law and  Massachusetts  Corporation  Law.  The
discussion is intended to highlight important similarities and differences.


                                      -78-
<PAGE>


     Authorized Capital

     As indicated  above,  Hagler Bailly is authorized to issue up to 20,000,000
(50,000,000,  if the Certificate  Amendment is approved)  shares of common stock
and 5,000,000  shares of preferred  stock.  PHB is authorized to issue 8,000,000
shares of PHB common stock.

     Directors

     Hagler  Bailly's  Certificate  of  Incorporation  provides  that the Hagler
Bailly Board of Directors will be divided into three classes,  with directors in
each class elected for three-year staggered terms. The Hagler Bailly Certificate
of Incorporation  further provides that the size of the Board of Directors shall
be fixed by the Board of Directors and  initially  fixes the number of directors
at seven.  The Hagler Bailly Bylaws  provide that the number of directors may be
determined  by a  resolution  of the  Board  or the  stockholders  at an  annual
meeting.  The number of Hagler Bailly  directors will be increased by two if the
Merger closes.  The Bylaws of PHB provide that the number of PHB directors shall
be between one and 50 and may be changed by a majority of the directors  then in
office  or by  the  stockholders  by a  vote  of  the  majority  of  the  shares
outstanding and entitled to vote. PHB does not have a classified Board.

     Board Vacancies and the Removal of Directors

     Under Delaware  Corporation Law, vacancies and newly created  directorships
may be filled by a  majority  of  directors  then in  office,  unless  otherwise
provided in the  corporation's  certificate of incorporation or by-laws.  Hagler
Bailly's  Certificate  of  Incorporation  and  Bylaws  provide  that  a  vacancy
occurring in the Board of Directors, including a vacancy created by any increase
in the number of  directors,  shall be filled for the remainder of the unexpired
term by a majority  vote of the  directors  then in office,  though  less than a
quorum. Both Delaware Corporation Law and Hagler Bailly's Bylaws provide that if
at the time of filling any vacancy or newly created directorship,  the directors
then  in  office  constitute  less  than a  majority  of  the  entire  board  as
constituted immediately prior to any increase,  stockholders owning at least 10%
of the outstanding shares may request the Delaware Court of Chancery to order an
election to be held to fill any such vacancies or newly created directorships or
to replace the directors chosen by the directors then in office.

     Under  Massachusetts  Corporation  Law, unless the articles of organization
provide  otherwise,  any vacancy in the board of directors,  however  occurring,
including a vacancy  resulting from  enlargement of the board and any vacancy in
any other office, may be filled in the manner prescribed in the by-laws,  or, in
the absence of any such provision in the by-laws, by the directors. PHB's Bylaws
provide that a vacancy occurring in the Board of Directors,  including a vacancy
resulting from the  enlargement of the Board of Directors,  may be filled by the
stockholders or a majority of the directors then in office.

     Under  Delaware  Corporation  Law,  in the case of a  Delaware  corporation
having a classified  board,  stockholders  may remove a director  only for cause
unless the  certificate of  incorporation  otherwise  provides.  Hagler Bailly's
Certificate  of  Incorporation  provides that a director may be removed only for
cause and then only by the affirmative  vote of at least two-thirds of the total
votes eligible to be voted at a duly  constituted  meeting of  stockholders  and
with 30 days' written notice to the director whose removal is to be considered.

     Under  Massachusetts  Corporation  Law, any director or the entire board of
directors  may be  removed,  except as  otherwise  provided  in the  articles of
organization or by-laws,  with or without cause, by the holders of a majority of
the shares  entitled to vote at an election of directors.  PHB's Bylaws  provide
that a  director  may be  removed,  (a)  with or  without  cause  by a vote of a
majority in interest of the stock issued and outstanding and entitled to vote at
an  election  of  directors  or (b) with  cause by the  Board,  by a vote of the
majority of those  directors  then in office.  A PHB director may be removed for
cause only after reasonable notice and opportunity to be heard.

     Interested Directors and Other Transactions

     Delaware Corporation Law provides that no transaction between a corporation
and a director or officer,  or any entity in which any of them has an  interest,
is void or voidable  solely for this  reason,  solely  because  the  director or
officer is present at or  participates  in the meeting of the board or committee
which authorizes the contract or transaction,  or solely because of his or their
votes are counted for such purpose if: (a) after full disclosure the transaction
is approved by the disinterested directors,  which may be less than a quorum, or
the  stockholders  or (b) the transaction is fair to the corporation at the time
it is approved.  Massachusetts  Corporation Law provides that directors who vote
for and officers who knowingly participate in loans to officers or directors are
jointly and severally  liable to the  corporation for any part of the loan which
is not repaid,  unless:  (a) a majority of the  directors  who are not direct or
indirect recipients of such loans or (b) the holders of a majority of the shares
entitled to vote for such  directors,  have approved or ratified the loan as one
which in the judgment of such directors or stockholders, as the case may be, may
reasonably  be  expected  to  benefit  the   corporation.   PHB's   Articles  of
Organization  provide that any  transaction  entered  into by PHB shall,  in the
absence of fraud, not be affected by a director's pecuniary or other interest in
such  transaction  provided  that such  interest  is  disclosed  to the Board of
Directors prior to its approval of the transaction.

     Indemnification and Limitation of Liability

     Delaware  Corporation  Law generally  permits  broader  indemnification  of
directors  and  officers  than  does  Massachusetts  Corporation  Law.  Although
Delaware  Corporation Law and Massachusetts  Corporation Law permit corporations
to  adopt  charter  provisions  limiting  the  liability  of  directors  to  the
corporation  and its  stockholders  under certain  circumstances,  the permitted
limitations  under  Delaware  Corporation  Law are somewhat  more  beneficial to
directors than those under Massachusetts Corporation Law.

     Delaware  Corporation Law generally  permits  indemnification  of officers,
directors,  employees  and agents of a  Delaware  corporation  against  expenses
(including  attorneys' fees) incurred in connection with a derivative action and
against expenses (including attorneys' fees), judgments,  fines and amounts paid
in settlements incurred in connection with a third party action,  provided there
is a determination  by a majority vote of disinterested  directors,  independent
legal counsel or the stockholders that the person seeking  indemnification acted
in good faith and in a manner  reasonably  believed to be in, or not opposed to,
the best  interests  of the  corporation  (and,  with respect to any third party
criminal action or proceeding,  had no reasonable  cause to believe this conduct
was unlawful).  Without court approval,  however, no indemnification may be made
in respect of any derivative  action in which such person is adjudged  liable to
the corporation. Massachusetts Corporation Law similarly permits indemnification
of  expenses  in  a   derivative   or   third-party   action,   except  that  no
indemnification  shall be provided  for any person with respect to any matter as
to which he shall have been  adjudicated  not to have acted in good faith in the
reasonable  belief that his action was in the best interests of the  corporation
or, to the  extent  that such  matter  relates to  service  with  respect to any
employee   benefit  plan,  in  the  best  interests  of  the   participants   or
beneficiaries of such benefit plan.

     Delaware Corporation Law requires indemnification when the individual being
indemnified  has  successfully  defended the action on the merits or  otherwise.
Massachusetts  Corporation  Law  merely  permits  indemnification  to the extent
authorized in the  corporation's  articles of  organization or its by-laws or as
set forth in a vote of stockholders.

     Expenses  incurred by an officer or director in  defending an action may be
paid in advance under Delaware and Massachusetts Corporation Law if such officer
or director undertakes to repay such amounts should it be determined  ultimately
that he is not  entitled  to  indemnification.  Delaware  Corporation  Law  also
permits the  advancement of expenses to employees and agents of the  corporation
without such an  undertaking to repay such amounts.  In addition,  both Delaware
and  Massachusetts  Corporation  Law permit a corporation to purchase  indemnity
insurance  for the 


                                      -80-
<PAGE>


benefit of its  officers,  directors,  employees  and agents  whether or not the
corporation  would have the power to indemnify  against the liability covered by
the policy.

     Hagler Bailly's  Certificate of Incorporation  requires  indemnification of
directors,  officers,  employees  and agents of Hagler Bailly to the full extent
authorized  by  Delaware  Corporation  Law.  Hagler  Bailly's  Bylaws  and PHB's
Articles of Organization provide that each of the corporations will indemnify an
officer or  director  (or an  employee  and other  persons in the case of Hagler
Bailly),  if he or she acts in good faith and in a manner he or she  believes to
be in the best  interests  of Hagler  Bailly or PHB, as  applicable,  and,  with
respect to a criminal proceeding,  had no reasonable cause to believe his or her
conduct was unlawful. Hagler Bailly's Certificate of Incorporation provides that
no director shall be personally liable to the corporation or any stockholder for
monetary  damages  for  breach  of  fiduciary  duty  as a  director  other  than
liability:  (a)  for  any  breach  of the  director's  duty  of  loyalty  to the
corporation or its stockholders;  (b) for acts or omissions not in good faith or
which involve intentional  misconduct or a knowing violation of law; (c) for any
payment of a dividend or approval of a stock  repurchase  that is illegal  under
Section 174 of Delaware  Corporation Law or (d) for any transaction from which a
director derived an improper personal  benefit.  Also, PHB's Articles and Hagler
Bailly's Bylaws provide that the respective corporations may obtain insurance on
behalf of directors, officers, employees and other persons.

     After  the  Merger,  the   indemnification   and  limitation  of  liability
provisions  of: (i)  Massachusetts  Corporation  Law will apply to the Surviving
Corporation  and (ii) Delaware  Corporation Law will continue to apply to Hagler
Bailly.

     Inspection Rights

     Inspection  rights under Delaware  Corporation  Law are more extensive than
under   Massachusetts   Corporation   Law.  Under  Delaware   Corporation   Law,
stockholders have the right to inspect a corporation's stock ledger, stockholder
lists and other  books and  records for a proper  purpose.  Under  Massachusetts
Corporation Law, a corporation's  stockholders  have a right to inspect only the
corporation's  charter,  by-laws,  records of all meetings of incorporators  and
stockholders and transfer records.

     Special Meetings of Stockholders

     The Hagler Bailly Bylaws  provide that the president or the  secretary,  at
the  request of a majority  of the Board or  stockholders  owning a majority  in
amount of the capital stock entitled to vote, may call a special meeting.  Under
PHB's  Bylaws,  a  special  meeting  of  stockholders  of PHB may be  called  by
stockholders  entitled  to vote  10% or more of the  votes  of the  stockholders
entitled  to  vote at the  meeting  or by the  president  or a  majority  of the
directors then in office.

     Action by Consent of the Stockholders

     Under Delaware Corporation Law and Hagler Bailly's Bylaws, any action to be
taken by the  stockholders  of Hagler  Bailly  may be taken  without a  meeting,
without prior notice and without a vote, if the  stockholders  having the number
of votes that would be  necessary  to take such action at a meeting at which all
of the  stockholders  were  present and voted  consent to the action in writing.
Under  Massachusetts  Corporation Law, any action to be taken by stockholders of
PHB may be taken without a meeting only if all stockholders  entitled to vote on
the matter consent to the action in writing.

     Amendment of Certificate, Articles or Bylaws

     Pursuant to Delaware  Corporation  Law and Hagler  Bailly's  Certificate of
Incorporation,  Hagler Bailly's Certificate may be amended by a Board resolution
and the approval of a majority of the outstanding  stock entitled to vote on the
amendment. Hagler Bailly's Bylaws provide that they may be amended by either the
Board or the stockholders.


                                      -81-
<PAGE>


     Pursuant to Massachusetts  Corporation  Law,  amendments to a corporation's
articles  of  organization  relating  to  certain  changes  in capital or in the
corporate  name  require  the vote of at least a majority of each class of stock
outstanding and entitled to vote thereon.  Amendments  relating to other matters
require a vote of at least two-thirds of each class  outstanding and entitled to
vote thereon or, if the articles of organization so provide, a greater or lesser
proportion but not less than a majority of the outstanding shares of each class.
The PHB Articles do not alter the required vote.

     Massachusetts Corporation Law provides that by-laws may be made, amended or
repealed by  stockholders,  provided  that,  if  authorized  by the  articles of
organization,  the by-laws may provide that the directors may also make,  amend,
or repeal the by-laws in whole or in part,  except with respect to any provision
thereof which by law, or in accordance  with the articles of organization or the
by-laws,  requires action by the  stockholders.  PHB's Articles provide that its
Bylaws may be amended or repealed by the Board to the extent  permitted  by law.
PHB's  Bylaws  provide that they may be amended by the Board or by a vote of the
majority of all stock issued,  outstanding  and entitled to vote at a meeting or
by unanimous written consent of all stockholders entitled to vote.

     Proxies  

     Delaware  Corporation Law permits a proxy to be valid for up to three years
unless the proxy provides for a longer  period.  Massachusetts  Corporation  Law
permits the  authorization  by a stockholder to vote by proxy to be valid for no
more than six months.

     Approval of Business Combinations and Asset Sales

     Under Delaware  Corporation  Law, the affirmative vote of a majority of the
shares of stock  outstanding  and  entitled  to vote is  necessary  to approve a
merger or asset  sale.  Generally,  under  Massachusetts  Corporation  Law,  the
affirmative vote of two-thirds of the shares of each class of stock  outstanding
and entitled to vote or which would be  adversely  affected by a merger or asset
sale is necessary to approve a merger or a sale of all or  substantially  all of
the  corporation's  assets  unless the  articles of  organization  provide for a
lesser  proportion of each class entitled to vote, but not less than a majority.
The PHB  Articles  do not  provide  for  such a lesser  proportion,  so that the
approval of any such merger or sale, including the Merger, requires a two-thirds
vote of each class entitled to vote.

     Dissenters' Rights

     Under  Massachusetts  Corporation Law,  dissenting  stockholders who follow
prescribed statutory procedures are entitled to dissenters' rights in connection
with any merger or sale of substantially  all the assets of a corporation and in
connection with certain mergers,  reclassifications and other transactions which
may adversely affect the rights or preferences of stockholders.  See "THE MERGER
- --  Dissenters'  Rights of  Appraisal"  and Annex E.  Delaware  Corporation  Law
provides  similar  rights  in  the  case  of  a  merger  or  consolidation  of a
corporation  except  that  such  rights  are  not  provided  as to  shares  of a
corporation listed on a national securities exchange or designated as a national
market  system  security on an  interdealer  quotation  systems by the  National
Association  of  Securities  Dealers,  Inc. or held of record by more than 2,000
stockholders  where such  stockholders  are  required to accept in such a merger
only:  (a) shares of the  surviving  or resulting  corporation;  (b) shares of a
corporation listed on a national  securities  exchange or held of record by more
than 2,000 holders; (c) cash in lieu of fractional shares or (d) any combination
thereof.  Delaware  Corporation  Law  does not  provide  dissenters'  rights  in
connection  with  sales of  substantially  all of the  assets of a  corporation,
reclassifications   of  stock  or  other   amendments  to  the   certificate  of
incorporation which adversely affect a class of stock; provided, however, that a
corporation  may provide in its  certificate  of  incorporation  that  appraisal
rights shall be available  as a result of an  amendment  to its  certificate  of
incorporation, a merger or a sale of all or substantially all of its assets. The
Hagler  Bailly  Certificate  of  Incorporation,  however,  does not  contain any
provisions as to appraisal rights.

     Payment of Dividends

     Delaware  Corporation  Law permits the payment of dividends  out of paid-in
and earned  surplus or out of net profits for the current and  preceding  fiscal
year.  There  are  no  restrictions  on  authorized   dividend   payments  under
Massachusetts Corporation Law.

     Anti-takeover Statutes and Provisions

     Section 203 of Delaware  Corporation Law (the "Delaware  Takeover Statute")
applies  to  Delaware  corporations  with a class of  voting  stock  listed on a
national  securities  exchange,  authorized  for  quotation  on the Nasdaq Stock
Market, or held of record by 2,000 or more persons,  and restricts  transactions
which may be entered into by such a corporation and certain of its stockholders.
The Delaware Takeover Statute provides, in essence, that a stockholder acquiring
more  than  15%,  but  less  than  85%,  of the  outstanding  voting  stock of a
corporation  subject to the statute and such person's  affiliates and associates
(each, an "Interested Person") may not engage in certain "Business Combinations"
(as defined therein) with the corporation for a period of three years subsequent
to the date on which the  stockholder  became an Interested  Person unless:  (a)
prior to such date the  corporation's  board of  directors  approved  either the
Business  Combination  or the  transaction  in which the  stockholder  became an
Interested   Person  or  (b)  the  Business   Combination  is  approved  by  the
corporation's board of directors and authorized by a vote of at least two-thirds
of the  outstanding  voting stock of the corporation not owned by the Interested
Person. The Delaware Takeover Statute defines the term "Business Combination" to
include a wide variety of transactions with or caused by an Interested Person in
which the Interested  Person receives or could receive a benefit on other than a
pro rata basis with other stockholders,  including mergers, certain asset sales,
certain  issuances of additional shares to the Interested  Person,  transactions
with the corporation which increase the proportionate interest of the Interested
Person or  transactions in which the Interested  Person  receives  certain other
benefits.

     Massachusetts Corporation Law contains an analogous anti-takeover law which
is set forth in Chapter 110F of the General Laws of Massachusetts.  Chapter 110F
does not apply to the Merger  because the  transaction  has been approved by the
PHB Board.


                            THE CERTIFICATE AMENDMENT

     The  Hagler  Bailly  Board  of  Directors  has  unanimously   approved  the
Certificate Amendment.  The Hagler Bailly Board of Directors has determined that
the proposed  amendment  to Hagler  Bailly's  Certificate  of  Incorporation  is
advisable and in the best interests of Hagler Bailly and its  stockholders,  and
unanimously  recommends  that the holders of Hagler  Bailly common stock vote to
approve the amendment.  Approval of the Certificate Amendment is not a condition
to the Merger.

     Hagler Bailly's  Certificate of Incorporation  currently  provides that the
total  number of shares of all classes of capital  stock that Hagler  Bailly has
authority to issue is  25,000,000,  consisting  of  20,000,000  shares of Hagler
Bailly common stock and 5,000,000 shares of preferred stock, par value $0.01 per
share.  The  Certificate  Amendment's  purpose  is to  increase  the  number  of
authorized  shares of Hagler Bailly common stock from  20,000,000 to 50,000,000,
resulting  in an increase in the number of  authorized  shares of capital  stock
from  25,000,000  to  55,000,000.  The increase will be effected by amending the
relevant part of Article 4 of Hagler Bailly's  Amended and Restated  Certificate
of Incorporation to read as follows:

     "4. Capital Stock. The total number of shares of all classes of the capital
     stock which the corporation shall have authority to issue is:

     50,000,000 shares, par value one cent ($0.01) per share of common stock"


                                      -83-
<PAGE>


     Of the  20,000,000  presently  authorized  shares of Hagler  Bailly  common
stock,  9,627,503  shares  were issued and  outstanding  as of July 15, 1998 and
3,200,000  shares were reserved for issuance with respect to the Hagler Bailly's
stock  option  plans.  As of July 15, 1998,  no shares of  preferred  stock were
outstanding.  Under the terms of the Merger Agreement,  Hagler Bailly will issue
6,600,000  shares of Hagler Bailly common stock,  subject to adjustment,  to the
holders of PHB common stock.  Accordingly,  if the Merger  closes,  only 790,264
shares of authorized but not outstanding and unreserved  shares of Hagler Bailly
common stock will remain available for future issuance.

     The Board of Directors has  determined  that the  Certificate  Amendment is
advisable and in the best interests of Hagler Bailly and its  stockholders,  and
unanimously  recommends that stockholders approve it. Other than securities that
would be issued in  connection  with the  Merger,  Hagler  Bailly has no present
intention of issuing any other authorized but unissued and unreserved  shares of
Hagler Bailly capital stock. The Board of Directors  believes that the increased
number of shares of Hagler Bailly common stock, regardless of whether the Merger
is consummated or not, will benefit Hagler Bailly and its stockholders.  It will
make a sufficient number of shares available in the future for use in connection
with possible stock  dividends or splits,  raising  additional  capital  through
public offerings or private placements, possible future mergers or acquisitions,
or under employee option or stock ownership plans.

     The unissued and  unreserved  shares of Hagler  Bailly common stock will be
available  for any  proper  corporate  purpose,  as  authorized  by the Board of
Directors, without further approval by the Hagler Bailly stockholders, except as
otherwise required by law or the rules of the Nasdaq Stock Market. Hagler Bailly
stockholders  do not have any preemptive or other rights to purchase  additional
shares of Hagler Bailly common stock.  Issuances of additional  shares of Hagler
Bailly common stock or securities  convertible  into Hagler Bailly common stock,
therefore, may have a dilutive effect on existing stockholders of Hagler Bailly.

     In the event of a proposed  merger,  tender offer or other  attempt to gain
control of Hagler  Bailly,  it may be  possible  for the Board of  Directors  to
approve the issuance of shares of Hagler Bailly common stock or preferred  stock
in a  transaction  that could have the effect of  frustrating  or impeding  such
takeover  attempt.  The Board of  Directors  has no current  intention  to issue
authorized but unissued  shares for such purpose.  The Board of Directors is not
aware of any specific  effort to accumulate  Hagler Bailly common stock in order
to  obtain  control  of  Hagler  Bailly  by means  of  merger,  tender  offer or
otherwise.


                         THE STOCK OPTION PLAN AMENDMENT

     The Hagler  Bailly  Board of Directors  has  approved and is proposing  for
stockholder  approval,  the Stock Option Plan Amendment which would increase the
number of shares of Hagler Bailly common stock  reserved for issuance  under the
Stock Option Plan by 1,800,000 shares (from 3,200,000 to 5,000,000  shares).  As
of July 20, 1998,  options with  respect to  1,384,713  shares of Hagler  Bailly
common  stock  were  outstanding  under the Stock  Option  Plan.  Hagler  Bailly
management  believes that stock options have been and will continue to be one of
the most important methods of attracting and retaining key personnel responsible
for the development and growth of Hagler Bailly's  business.  In order to permit
Hagler  Bailly to continue to use stock  options as an incentive to its officers
and key personnel and as a means to promote  increased  stockholder  value,  the
Board  believes  that the Stock  Option Plan needs to be amended to increase the
number of shares  reserved for issuance.  The Board of Directors has  determined
that the Stock Option Plan  Amendment is advisable and in the best  interests of
Hagler Bailly and its stockholders, and recommends that stockholders approve it.

     THIS AGREEMENT AND PLAN OF MERGER (this "Agreement") is entered into this
11th day of June, 1998, by and among HAGLER BAILLY, INC., a Delaware corporation
("HAGLER BAILLY"), PHB MERGER CORP., a Delaware corporation and a wholly-owned

a Massachusetts corporation ("PHB").

     WHEREAS, the Boards of Directors of HAGLER BAILLY and PHB have each
determined that it is in the best interests of their respective stockholders
that HAGLER BAILLY and PHB enter into a business combination under which Merger
Sub, a wholly-owned subsidiary of HAGLER BAILLY, will merge with and into PHB
pursuant to the Merger (as defined below) and HAGLER BAILLY and PHB desire to
enter into the "merger of equals" transaction contemplated hereby, and, in

other things, certain stockholders of HAGLER BAILLY have agreed to vote their

(the "PHB Support Agreement"), pursuant to which, among other things, certain
stockholders of PHB have agreed to vote their respective shares of common stock
of PHB in favor of this Agreement, the Merger and the other transactions
contemplated by this Agreement;

     WHEREAS, as an inducement to PHB to enter into this Agreement and the PHB

set forth in Section 7.13 below.

     WHEREAS, in connection with the transactions contemplated by this Agreement
and as an inducement to HAGLER BAILLY and Merger Sub to enter into this
Agreement, certain directors of PHB have entered into employment agreements with
HAGLER BAILLY (the "Employment Agreements"), the effectiveness of which is
conditioned upon the consummation of the Merger;

     WHEREAS, in connection with the transactions contemplated by this Agreement
and as a condition to consummation of the Merger, HAGLER BAILLY, Merger Sub, the
Stockholders' Representative (as defined in Section 2.2(b) hereof) and State

pursuant to which a certain number of the shares of common stock, par value $.01
per share, of HAGLER BAILLY (the "HAGLER BAILLY Common Stock"), to be issued as
consideration in the Merger will be retained in escrow;

     WHEREAS, at Closing, HAGLER BAILLY shall execute a Registration Rights
Agreement in the form attached hereto as Exhibit B (the "Registration Rights
Agreement" and, together with the HAGLER BAILLY Support Agreement, the PHB
Support Agreement, the Escrow Agreement and the Employment Agreements, the
"Related Agreements"), pursuant to which stockholders of PHB who execute the
Registration Rights Agreement will obtain "piggyback" registration and
"tag-along" rights;

     NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth in this
Agreement, the parties hereto agree as follows:


                                    ARTICLE I
                                   THE MERGER


     SECTION 1.1. The Merger.

     Upon the terms and subject to the conditions set forth in this Agreement,
and in accordance with the Massachusetts Business Corporation Law (the "MBCL")
and the Delaware General Corporation Law ("DGCL"), at the Effective Time (as
defined in Section 1.2), Merger Sub shall be merged with and into PHB (the
"Merger"). As a result of the Merger, the separate corporate existence of Merger
Sub shall cease, and PHB shall continue as the surviving corporation of the
Merger (sometimes referred to herein as the "Surviving Corporation") as a
wholly-owned subsidiary of 


                                      -2-
<PAGE>

HAGLER BAILLY. The name of the Surviving Corporation shall be Putnam, Hayes &
Bartlett, Inc.


     SECTION 1.2. Effective Time.

     At the Closing (as defined in Section 1.6), the parties hereto shall cause
the Merger to be consummated by filing (a) articles of merger with the Secretary
of State of the Commonwealth of Massachusetts (the "Massachusetts Articles of
Merger") in such form as required by, and executed in accordance with the
relevant provisions of the MBCL, and (b) articles of merger with the Secretary
of State of the State of Delaware (the "Delaware Articles of Merger") in such
form as required by, and executed in accordance with the relevant provisions of
the DGCL (the Massachusetts Articles of Merger and the Delaware Articles of
Merger being collectively known as the "Articles of Merger"). The Articles of
Merger shall be filed in such form as reasonably approved by PHB and HAGLER
BAILLY prior to such filing, and the date and time of the filing of the latter
of the two Articles of Merger (or such subsequent date or time specified
therein) shall be the "Effective Time".


     SECTION 1.3. Effect of the Merger.

     At the Effective Time, the effect of the Merger shall be as provided in
this Agreement and the applicable provisions of the MBCL and DGCL. Without
limiting the generality of the foregoing, and subject thereto, at the Effective
Time, except as otherwise provided herein, all the property, rights, privileges,
powers and franchises of Merger Sub and PHB shall vest in the Surviving
Corporation, and all debts, liabilities and duties of Merger Sub and PHB shall
become the debts, liabilities and duties of the Surviving Corporation.


     SECTION 1.4. Articles of Organization; Bylaws.

     At the Effective Time:

          (a) the articles of organization of PHB, as in effect immediately
     prior to the Effective Time and as amended by the Articles of Merger, shall
     be the articles of organization of the Surviving Corporation; and

          (b) the bylaws of the Surviving Corporation shall be as set forth in
     Exhibit H hereto.


     SECTION 1.5. Directors and Officers.

     Henri-Claude Bailly and Howard W. Pifer, III shall be the sole directors of
the Surviving Corporation, to hold office in accordance with the articles of
organization and bylaws of the Surviving Corporation; and the officers of PHB
shall continue as the officers of the Surviving Corporation, in each case until
their 


                                      -3-
<PAGE>

respective successors are duly elected or appointed and qualified. HAGLER BAILLY
shall take all action necessary so that the indemnification obligations set
forth in PHB's Articles of Incorporation and By-laws, in each case as of the
date of this Agreement, shall survive the Merger and shall not be amended,
repealed or otherwise modified for a period of six years after the Effective
Time in any manner that would adversely affect the rights thereunder of the
individuals who on or prior to the Effective Time were directors or officers of
PHB or the PHB Subsidiaries with respect to occurrences prior to the Effective
Time.


     SECTION 1.6. Merger Deliveries.

     Subject to the terms and conditions of this Agreement, the Merger will take
place as promptly as practicable after satisfaction of the latest to occur or,
if permissible, waiver, of the conditions set forth in Article VIII hereof (the
"Merger Date"). All deliveries required as a condition to, or upon the
effectiveness of, the Merger shall be made at the offices of Hogan & Hartson
L.L.P., 555 Thirteenth Street, N.W., Washington, D.C. 20004, unless another date
or place is agreed to by the parties hereto.


     SECTION 1.7. Subsequent Actions.

     If, at any time after the Effective Time, the Surviving Corporation shall
consider or be advised that any deeds, bills of sale, assignments, assurances or
any other actions or things are necessary or desirable to continue in, vest,
perfect or confirm of record or otherwise in the Surviving Corporation, its
right, title or interest in, to or under any of the rights, properties,
privileges, franchises or Assets of either of its constituent corporations
acquired or to be acquired by the Surviving Corporation as a result of, or in
connection with, the Merger or otherwise to carry out this Agreement, the
officers and directors of the Surviving Corporation shall be directed and
authorized to execute and deliver, in the name and on behalf of either of such
constituent corporations, all such deeds, bills of sale, assignments and
assurances and to take and do, in the name and on behalf of each of such
corporations or otherwise, all such other actions and things as may be necessary
or desirable to vest, perfect or confirm any and all right, title and interest
in, to and under such rights, properties, privileges, franchises or Assets in
the Surviving Corporation or otherwise to carry out this Agreement.


     SECTION 1.8. Tax and Accounting Treatment of the Merger.

     It is intended by the parties hereto that the Merger shall:

          (a) constitute a reorganization of Merger Sub and PHB within the
     meaning of Section 368 of the Internal Revenue Code of 1986, as amended
     (the "Code"); and



                                      -4-
<PAGE>

          (b) qualify for accounting treatment as a pooling of interests.

     The parties hereby adopt this Agreement as a "plan or reorganization" of
Merger Sub and PHB within the meaning of Sections 1.368-2(g) and 1.368-3(a) of
the United States Treasury Regulations.


                                   ARTICLE II
               CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES


     SECTION 2.1. Conversion of Securities.

     At the Effective Time, by virtue of the Merger and without any action on
the part of HAGLER BAILLY, Merger Sub, PHB or the holders of the following
securities:

          (a) PHB Common Stock. Subject to the provisions hereof, each share of
     common stock, par value $0.01 per share, of PHB (the "PHB Common Stock")
     issued and outstanding immediately prior to the Effective Time shall,
     except as otherwise provided in Section 2.1(b), be converted into and
     exchangeable for, and immediately after the Effective Time HAGLER BAILLY
     shall be required to deliver certificates pursuant to Section 2.4 hereof, a
     number of shares of HAGLER BAILLY Common Stock (the "Merger Stock") equal
     to:

               (i) 6,600,000, divided by

               (ii) the number of shares of PHB Common Stock issued and
          outstanding immediately prior to the Effective Time.

          All such shares of PHB Common Stock shall cease to be outstanding and
     shall automatically be canceled and retired and shall cease to exist, and
     each certificate (the "PHB Certificate") previously evidencing any such
     shares shall thereafter represent only the right to receive the HAGLER
     BAILLY Common Stock. The holders of certificates previously evidencing such
     shares of PHB Common Stock outstanding immediately prior to the Effective
     Time (the "PHB Stockholders") shall cease to have any rights with respect
     to such shares of PHB Common Stock, except as otherwise provided herein.
     After the Merger Date, there will be no adjustment to the number of shares
     of Merger Stock into which the PHB Common Stock is convertible. For
     purposes of this Agreement, the parties agree and acknowledge that the term
     "Merger Stock" shall include the Escrow Stock.

          (b) Treasury Stock. All shares of capital stock of PHB held in the
     treasury of PHB immediately prior to the Effective Time shall be canceled

                                      -5-
<PAGE>

     and extinguished without any conversion thereof and no HAGLER BAILLY Common
     Stock or other consideration shall be delivered or deliverable in exchange
     therefor.

          (c) Merger Sub Stock. Each share of common stock, par value $.01 per
     share, of Merger Sub issued and outstanding immediately prior to the
     Effective Time shall be converted into and exchanged for one (1) duly and
     validly issued, fully paid and nonassessable share of common stock of the
     Surviving Corporation.

          (d) No Fractional Shares. No fraction of a share of HAGLER BAILLY
     Common Stock shall be issued in connection with the Merger. In lieu of any
     such fractional share, the holder of PHB Common Stock that would be
     entitled to a fractional share shall have the right to receive an amount in
     cash, without interest, equal to the product of such fractional part of
     HAGLER BAILLY Common Stock multiplied by the reported closing price of a
     share of HAGLER BAILLY Common Stock on the Nasdaq Stock Market on the last
     business day prior to the Merger Date.


     SECTION 2.2. Escrowed Merger Stock; Stockholders' Representative.

          (a) When making the issuances of shares of HAGLER BAILLY Common Stock
     required by Section 2.1(a) and pursuant to the Escrow Agreement, HAGLER
     BAILLY shall withhold and deposit in escrow from the PHB Stockholders One
     Hundred Fifty Thousand (150,000) shares of HAGLER BAILLY Common Stock
     issuable pursuant to Sections 2.1(a) (the "Escrow Stock"). The Escrow Stock
     will be placed in escrow pursuant to the Escrow Agreement as security for
     the faithful performance of the indemnity obligations of the PHB
     Stockholders under Article X of this Agreement. The Escrow Stock shall be
     registered in the name of the Escrow Agent as nominee for the PHB
     Stockholders. The Merger Stock otherwise distributable as of the Effective
     Time to each PHB Stockholder in connection with the Merger as provided in
     Sections 2.1(a) shall be proportionally reduced to reflect the deposit in
     escrow of those portions of the aggregate Merger Stock required to be
     deposited in escrow as described in this Section 2.2, and such Escrow Stock
     shall be released to the PHB Stockholders or HAGLER BAILLY, as the case may
     be, only in accordance with the terms of the Escrow Agreement and this
     Agreement.

          (b) William Dickenson shall, by virtue of the Merger, be authorized
     and empowered to act, for and on behalf of any or all of the PHB
     Stockholders (with full power of substitution in the premises), in
     connection with the indemnity provisions of Article X as they relate to PHB
     generally and such other matters as are reasonably necessary for the
     consummation of 


                                      -6-
<PAGE>

     the transactions contemplated hereby including, without limitation, (i) to
     review all claims for indemnification asserted by any HAGLER BAILLY
     Indemnified Person, and, to the extent deemed appropriate, dispute,
     question the accuracy of, compromise, settle or otherwise resolve any and
     all such claims, (ii) to compromise on their behalf with HAGLER BAILLY any
     claims asserted thereunder, (iii) to authorize payments to be made with
     respect to any such claims for indemnification, (iv) to execute and deliver
     on behalf of the PHB Stockholders any document or agreement contemplated by
     or necessary or desirable in connection with this Agreement, the Escrow
     Agreement and the transactions contemplated hereby and thereby, and (v) to
     take such further actions including coordinating and administering
     post-closing matters related to the rights and obligations of the PHB
     Stockholders as are authorized in this Agreement (the above named
     representative, as well as any subsequent representative of the PHB
     Stockholders appointed by the PHB Stockholders being referred to herein as
     the "Stockholders' Representative"). The Stockholders' Representative shall
     not be liable to any PHB Stockholder, HAGLER BAILLY, the Surviving
     Corporation or their respective affiliates or any other person with respect
     to any action taken or omitted to be taken by the Stockholders'
     Representative in his role as Stockholders' Representative under or in
     connection with this Agreement unless such action or omission results from
     or arises out of fraud or intentional misconduct on the part of the
     Stockholders' Representative; provided, however, that the Stockholders'
     Representative shall not be liable to any PHB Stockholder in the event that
     in the exercise of his reasonable judgment, the Stockholders'
     Representative believes there will not be adequate resources available to
     cover potential costs and expenses to contest a claim made by HAGLER BAILLY
     against the Escrow Stock. HAGLER BAILLY and Merger Sub shall be entitled to
     rely on such appointment and treat such Stockholders' Representative as the
     duly appointed attorney-in-fact of each PHB Stockholder.


     SECTION 2.3. PHB Options.

     PHB shall terminate the 1992 Non-Qualified Stock Option Plan or any other
stock option plan or agreement of PHB by which employees or PHB Stockholders of
PHB are permitted to purchase PHB Common Stock (collectively, the "PHB Stock
Option Plans") as of the Effective Time and shall take all such action as is
necessary to terminate each outstanding option or right to purchase shares of
PHB Common Stock, if any (collectively, the "PHB Options") so that on or after
the Effective Time no holder of a PHB Option or participant or former
participant in the PHB Stock Option Plans shall have any right to purchase
shares of PHB Common Stock or any other equity interest in PHB or the Surviving
Corporation.

     SECTION 2.4. Exchange of Certificates.

          (a) Exchange Agent. Prior to the Merger Date, HAGLER BAILLY and PHB
     shall jointly designate a bank or trust company to act as exchange agent
     hereunder (the "Exchange Agent") to effect the exchange of PHB Common Stock
     for HAGLER BAILLY Common Stock. At the Effective Time, HAGLER BAILLY shall,
     on behalf of Merger Sub, deposit with or for the account of the Exchange
     Agent (i) stock certificates representing the Merger Stock issuable
     pursuant to Section 2.1(a) (less certificates representing the shares of
     Escrow Stock to be deposited in escrow pursuant to this Agreement and the
     Escrow Agreement), which shares of Merger Stock shall be deemed to have
     been issued at the Effective Time and (ii) sufficient cash to pay for
     fractional shares contemplated to be paid pursuant to Section 2.1(d).

          (b) Exchange Procedures. Promptly after the Effective Time,
     certificates representing PHB Common Stock shall be canceled, and,
     simultaneously with such cancellation, HAGLER BAILLY shall issue
     certificates with respect to the canceled PHB Common Stock for each PHB
     Stockholder. All such certificates (the "Merger Stock Certificates") shall
     be registered in the name of each PHB Stockholder and shall represent the
     total number of shares of HAGLER BAILLY Common Stock issuable pursuant to
     the Merger in respect of shares of PHB Common Stock held by such PHB
     Stockholder (less the PHB Stockholder's proportionate interest in the
     Escrow Stock) and the second certificate, representing the shares of Escrow
     Stock (the "Escrow Stock Certificate"), shall be issued in the name of the
     Escrow Agent as nominee of each PHB Stockholder.

     Prior to or promptly after the Effective Time, HAGLER BAILLY shall cause
the Exchange Agent to mail to each PHB Stockholder (i) instructions for use in
surrendering such PHB Certificates in exchange for certificates representing
HAGLER BAILLY Common Stock and (ii) a form of letter of transmittal specifying
that delivery shall be effected, and risk of loss and title to the PHB
Certificates shall pass, only upon proper delivery of the PHB Certificates to
the Exchange Agent. Upon surrender of a PHB Certificate for cancellation to the
Exchange Agent, together with such letter of transmittal duly executed, the
holder of such PHB Certificate shall be entitled to receive in exchange therefor
the Merger Stock Certificate, plus cash in lieu of fractional shares in
accordance with Section 2.1(d), and the PHB Certificate so surrendered shall
forthwith be canceled. At the Effective Time, HAGLER BAILLY shall issue the
Escrow Stock Certificate and transfer the Escrow Stock Certificate to the Escrow
Agent to be held in escrow. Until so surrendered, each PHB Certificate shall be
deemed at any time after the Effective Time for all corporate purposes of HAGLER
BAILLY, other than the payment of dividends and other distributions, if any, to
evidence ownership of the number of full shares of HAGLER BAILLY Common Stock
into which the shares of PHB Common Stock theretofore represented thereby shall
have been converted at 


                                      -8-
<PAGE>

the Effective Time. Unless and until any such PHB Certificate theretofore
representing PHB Common Stock is so surrendered, no dividend or other
distribution, if any, payable to the holders of record of HAGLER BAILLY Common
Stock as of any date subsequent to the Effective Time shall be paid to the
holder of such PHB Certificate in respect thereof. Upon the surrender of any
such PHB Certificate, however, the record holder of the certificate or
certificates representing shares of HAGLER BAILLY Common Stock issued in
exchange therefor shall receive from the Exchange Agent or from HAGLER BAILLY,
as the case may be, payment of the amount of dividends and other distributions,
if any, which as of any date subsequent to the Effective Time and until such
surrender shall have become payable with respect to such number of shares of
HAGLER BAILLY Common Stock ("Pre-Surrender Dividends"). No interest shall be
payable with respect to the payment of Pre-Surrender Dividends upon the
surrender of PHB Certificates.


     SECTION 2.5. Dissenting Shares.

          (a) Notwithstanding any other provisions of this Agreement to the
     contrary, shares of PHB Common Stock that are issued and outstanding
     immediately prior to the Effective Time and that are held by PHB
     Stockholders who shall not have voted in favor of the Merger and who shall
     have objected to the Merger in writing, stating that such PHB Stockholders
     intend to demand payment for the PHB Common Stock held by such PHB
     Stockholders in accordance with Section 156B ss. 86 of the MBCL
     (collectively, the "Dissenting Shares") shall not be converted into or
     represent the right to receive HAGLER BAILLY Common Stock pursuant to
     Section 2.1(a). Such PHB Stockholders shall be entitled to receive payment
     of the appraisal value of such shares of PHB Common Stock held by them in
     accordance with the provisions of Sections 156B ss.ss. 86-98 of the MBCL,
     except that all Dissenting Shares held by PHB Stockholders who shall have
     failed to perfect or who effectively shall have withdrawn or lost their
     rights to appraisal of such shares of PHB Common Stock under such Sections
     156B ss.ss. 86-98 shall thereupon be deemed to have been converted into and
     to have become exchangeable, as of the Effective Time, for the right to
     receive, without any interest thereon, the HAGLER BAILLY Common Stock, upon
     surrender of the certificate or certificates that formerly evidenced such
     shares of PHB Common Stock.

          (b) PHB shall give HAGLER BAILLY:

               (i) prompt notice of any written objections to the Merger and any
          written demands for payment and appraisal for any shares of PHB Common
          Stock, withdrawals of such objections or demands, and any other
          instruments served pursuant to the MBCL and received by PHB, and



                                      -9-
<PAGE>

               (ii) the opportunity to participate in all negotiations and
          proceedings with respect to demands for payment and appraisal under
          the MBCL.

               PHB shall not, except with the prior written consent of HAGLER
          BAILLY, voluntarily provide any consideration with respect to any
          demands for payment or appraisal of PHB Common Stock or offer to
          settle or settle any such demands.


     SECTION 2.6. Stock Transfer Books.

     At the Effective Time, the stock transfer books of PHB with respect to all
shares of capital stock of PHB shall be closed, and no further registration of
transfers of such shares of capital stock shall thereafter be made on the
records of PHB. In the event of a transfer of ownership of PHB Common Stock that
is not registered in the stock transfer records of PHB at the Effective Time, a
certificate or certificates representing the number of full shares of HAGLER
BAILLY Common Stock into which such shares of PHB Common Stock shall have been
converted shall be issued to the transferee together with a cash payment in lieu
of fractional shares, if any, in accordance with Section 2.1(d) hereof, and a
cash payment in the amount of Pre-Surrender Dividends, if any, in accordance
with Section 2.4 hereof, if the PHB Certificate or PHB Certificates is or are
surrendered to the Exchange Agent as provided in Section 2.4 hereof, accompanied
by all documents required to evidence and effect such transfer and by evidence
of payment of any applicable stock transfer tax.


     SECTION 2.7. Transferability of HAGLER BAILLY Common Stock.

     The shares of HAGLER BAILLY Common Stock to be issued and delivered to PHB
Stockholders in the Merger in accordance with the provisions of Section 2.1 will
not have been registered under the Securities Act of 1933, as amended (the
"Securities Act") or under the securities laws of any state as of the Closing.
Accordingly, those shares of HAGLER BAILLY Common Stock (together with any other
shares with respect to these shares received pursuant to Section 2.8) will have
restrictions on transferability under the Securities Act, state securities laws,
the rules, regulations and other administrative regulations promulgated under
the Securities Act and state securities laws and shall bear appropriate legends
to this effect as set forth in Section 2.9. In addition, where applicable, the
legend shall provide notice as to the restrictions on transfer pursuant to the
Affiliate Agreements (as defined in Section 7.9).




                                      -10-

     SECTION 2.8. Certain Adjustments.

     If between the date hereof and the Effective Time the outstanding shares of
HAGLER BAILLY Common Stock shall be changed into a different number of shares by
reason of any reclassification, stock dividend or stock split with a record date
within such period, the number of shares of Merger Stock shall be adjusted
accordingly to provide to PHB Stockholders the same economic effect as
contemplated by this Agreement prior to such reclassification, stock dividend or
stock split.


     SECTION 2.9. Legend; Subsequent Transfer.

     Each certificate representing HAGLER BAILLY Common Stock issued to PHB
Stockholders hereunder shall be stamped or otherwise imprinted with a legend
(the "Legend") in substantially the following form:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT") OR
     UNDER THE SECURITIES LAW OF ANY STATE. SUCH SECURITIES MAY NOT BE SOLD OR
     OFFERED FOR SALE OR OTHERWISE HYPOTHECATED OR DISTRIBUTED EXCEPT (A)
     PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT FOR SUCH SECURITIES UNDER
     THE ACT; OR (B)(i) PURSUANT TO A VALID EXEMPTION FROM SUCH REGISTRATION
     UNDER THE ACT AND UNDER APPLICABLE STATE SECURITIES LAWS, AND (ii) UPON
     RECEIPT BY HAGLER BAILLY OF AN OPINION OF COUNSEL FOR THE HOLDER, WHICH
     OPINION SHALL BE SATISFACTORY IN FORM AND SUBSTANCE TO HAGLER BAILLY, THAT
     SUCH SALE IS IN COMPLIANCE WITH THE ACT AND SUCH STATE SECURITIES LAW.

     HAGLER BAILLY agrees to remove such Legend upon the earlier of the
registration under the Securities Act of the HAGLER BAILLY Common Stock received
by PHB Stockholders or the second anniversary of the Effective Date.

<PAGE>

reasonably likely to have, a PHB Material Adverse Effect, and (c) PHB and the
PHB Subsidiaries have conducted their respective businesses in the ordinary
course of their businesses consistent with their past practices.


     SECTION 3.8. Legal Proceedings.

     Except as disclosed in Sections 4(f) and 12 of the PHB Disclosure, there

pending, or, to PHB's knowledge, threatened against or involving PHB or any of
the PHB Subsidiaries or their respective businesses or Assets, at law or in
equity or admiralty, or before or by any court, administrative, governmental,
arbitral, mediation or regulatory authority or body, domestic or foreign, that

contemplated hereby, and (b) no judgments, decrees, injunctions or orders of any
Government Entity or arbitrator outstanding against PHB or any of the PHB

     set forth a complete and correct list, as of the date of this Agreement, of
     all agreements of the following types to which PHB or any PHB Subsidiary is
     a party or may be bound (collectively, the "PHB Material Contracts"): (i)
     employment, severance, termination, consulting and retirement agreements
     that (y) are not terminable "at will" or (z) if terminated would trigger an
     obligation of PHB to pay additional compensation in excess of that
     contemplated by PHB's standard policies; (ii) agreements which involve
     payment by PHB of more than $250,000 or which are not cancelable without
     penalty by PHB in less than 60 days, (iii) royalty and licensing agreements
     of PHB acting as a licensor; (iv) agreements with any labor organization or
     other collective bargaining unit; (v) agreements for the purchase, sale or

     to the operation of PHB's business other than in the ordinary course of
     business or the grant of any preferential rights to purchase any such

     any PHB Subsidiary to indemnify any person not entered into in the ordinary
     course of business consistent with past practice; (viii) joint venture
     agreements or other agreements involving the sharing of profits; (ix)
     outstanding loans to any persons or entities or receivables due to PHB from

<PAGE>

     PHB Subsidiaries; (x) client engagement agreements, service agreements and
     other agreements with the top twenty-five PHB clients generating the
     highest amounts of aggregate revenue during fiscal years 1996 and 1997; or
     (xi) agreements (including, without limitation, agreements not to compete
     and exclusivity agreements) that reasonably could be interpreted to impose
     any restriction on any business operations of PHB or the PHB Subsidiaries,
     except for agreements containing restrictions that would not have a PHB
     Material Adverse Effect.

          (b) All the PHB Material Contracts are valid and in full force and
     effect on the date hereof (except to the extent they have previously
     expired in accordance with their terms) and constitute legal, valid and
     binding obligations of, and are legally enforceable against, PHB or any PHB
     Subsidiary which is a party thereto, and to the knowledge of PHB, the other
     party or respective parties thereto. All necessary governmental approvals
     with respect thereto required to be obtained by PHB or any PHB Subsidiary,
     as applicable, have been obtained, all necessary filings or registrations
     therefor required to be made by PHB or any PHB Subsidiary, as applicable,
     have been made, and, to the knowledge of PHB, there have been no threatened
     cancellations thereof and no outstanding disputes thereunder, except such
     that would not have a PHB Material Adverse Effect. Each of PHB and the PHB
     Subsidiaries has in all material respects performed all the obligations
     under the PHB Material Contracts required to be performed by PHB and the
     PHB Subsidiaries to date. PHB is not in default, and to PHB's knowledge, no
     party is in default, in any material respect under any of the PHB Material
     Contracts, and there has not occurred any event which (whether with or
     without notice, lapse of time or the happening or occurrence of any other
     event) would constitute such a default, except for defaults which would not
     in the aggregate reasonably be expected to have a PHB Material Adverse
     Effect. True and complete copies of all PHB Material Contracts have been
     delivered to HAGLER BAILLY or made available for inspection.


     SECTION 3.10. Environmental Matters.

          (a) Each of PHB and the PHB Subsidiaries has complied and is in
     compliance in all material respects with all Environmental Laws (as defined
     below). There are no pending or, to the knowledge of PHB and the PHB
     Subsidiaries, threatened actions, suits, claims, legal proceedings or other
     proceedings based on, and PHB and the PHB Subsidiaries have not directly or
     indirectly received any notice of any complaint, order, directive,
     citation, notice of responsibility, notice of potential responsibility, or
     information request from any Government Entity or any other person arising
     out of or attributable to: (i) the current or past presence at any part of
     the PHB Real Property (as defined below) of Hazardous Materials (as defined
     below) or any substances that pose a hazard to human health or an

<PAGE>

     impediment to working conditions; (ii) the current or past release or
     threatened release into the environment from the PHB Real Property

     or publicly owned treatment works) of any Hazardous Materials or any
     substances that pose a hazard to human health or an impediment to working
     conditions; (iii) the off-site disposal of Hazardous Materials originating
     on or from the PHB Real Property; or (iv) any violation of Environmental
     Laws at any part of the PHB Real Property or otherwise arising from PHB's

     employee benefit plans or fringe benefit plans, including, without
     limitation, all "employee benefit plans" as that term is defined in Section
     3(3) of the Employee Retirement Income Security Act of 1974, as amended
     ("ERISA"), currently adopted, maintained by, sponsored in whole or in part
     by, or contributed to by PHB or any PHB Subsidiary or for which PHB could
     incur a liability or any entity required to be aggregated with PHB (each, a
     "PHB Commonly Controlled Entity") pursuant to Section 414 of the Code for
     the benefit of present and former employees or directors of PHB and of each
     PHB Subsidiary or their beneficiaries, or providing benefits to such
     persons in respect of services provided to any such entity (collectively,

     Internal Revenue Service to be so qualified and to PHB's knowledge, no
     circumstances exist that could reasonably be expected by PHB to result in
     the revocation of any such determination. Each of the PHB Benefit Plans is
     in compliance with their terms and the applicable terms of ERISA and the
     Code and any other applicable laws, rules and regulations the breach or
     violation of which could result in a material liability to PHB or any PHB

          (c) No PHB ERISA Plan which is a defined benefit pension plan has any
     "unfunded current liability", as that term is defined in Section
     302(d)(8)(A) of ERISA, and the present fair market value of the assets of
     any such plan equals or exceeds the plan's "benefit liabilities", as that
     term is defined in Section 4001(a)(16) of ERISA, when determined under
     actuarial factors that would apply if the plan terminated in accordance
     with all applicable legal requirements. All contributions, premiums and

     and payable have been paid.

          (d) No PHB Benefit Plan is or has been a multiemployer plan within the
     meaning of Section 3(37) of ERISA (a "Multiemployer Plan"). Neither PHB nor
     any PHB Commonly Controlled Entity has completely or partially withdrawn
     from any Multiemployer Plan. No termination liability to the Pension
     Benefit Guaranty Corporation or withdrawal liability to any Multiemployer
     Plan that is material in the aggregate has been or is reasonably expected

     instrument. PHB has made available to HAGLER BAILLY complete copies of

     that are in the possession of PHB as of the date hereof.

          (f) No claim, lawsuit, arbitration or other action has been threatened
     or instituted against any PHB Benefit Plan.

          (g) Except as disclosed in Section 10 of the PHB Disclosure or as
     otherwise contemplated by the terms of this Agreement, the consummation of
     the transactions contemplated by this Agreement will not give rise to any
     liability, including, without limitation, liability for severance pay or
     termination pay, or accelerate the time of payment or vesting or increase
     the amount of compensation or benefits due to any employee, director or
     stockholder of PHB (whether current, former, or retired) or their
     beneficiaries solely by reason of such transactions. No amounts payable
     under any PHB Benefit Plan will fail to be deductible for federal income
     tax purposes by virtue of Section 280G or 162(m) of the Code.

          (h) Neither PHB nor any PHB Subsidiary maintains, contributes to, or
     in any way provides for any benefits of any kind (other than under Section
     4980B of the Code, the Federal Social Security Act, or a plan 


                                      -19-

Permits"), including, without limitation, under any applicable Environmental
Laws, as are necessary to own, lease and operate its respective properties and
to conduct their respective businesses as now being conducted, except for the
PHB Permits for which the failure to obtain would not have a PHB Material
Adverse Effect. PHB and each of the PHB Subsidiaries has fulfilled and performed
all of its material obligations with respect to such PHB Permits and no event
has occurred which allows, or after notice or lapse of time would allow,
revocation or termination thereof or results in any other material impairment of
the rights of the holder of any such PHB Permit. The businesses of PHB and the
PHB Subsidiaries are not being conducted in violation of any applicable law,
statute, ordinance, regulation, judgment, PHB Permit, order, decree, concession,

free and clear of all Encumbrances except liens for taxes not yet due and
payable to the PHB Real Property and to the assets owned by PHB and the PHB
Subsidiaries. All leases to which PHB or any of the PHB Subsidiaries is a party

such risks and losses as are customary for companies conducting the business as
conducted by PHB and the PHB Subsidiaries. Except as set forth in Section 14.8
of the PHB Disclosure, neither PHB nor any of the PHB Subsidiaries has received
notice of cancellation or termination with respect to any material insurance
policy of PHB or the PHB Subsidiaries and there are no pending claims under any

inventions (collectively, "PHB Intellectual Property") which are necessary for
the conduct of PHB or an PHB Subsidiary's business, other than PHB Intellectual
Property the lack of which would not reasonably be expected to have a PHB
Material Adverse Effect on the business, prospects, financial condition or
results of operation of PHB or any PHB Subsidiary. No rights to use PHB
Intellectual Property that is material to the business and prospects of PHB or
any PHB Subsidiary expire or are subject to termination at the election of
another party without cause or PHB's consent at a time or under circumstances
which would result in a PHB Material Adverse Effect. PHB has not received any

     term is defined in Section 3(3) of ERISA, currently adopted, maintained by,
     sponsored in whole or in part by, or contributed to by HAGLER BAILLY or any
     HAGLER BAILLY Subsidiary or for which HAGLER BAILLY could incur a liability
     or any entity required to be aggregated with HAGLER BAILLY (each, a "HAGLER
     BAILLY Commonly Controlled Entity") pursuant to Section 414 of the Code for
     the benefit of present and former employees or directors of HAGLER BAILLY
     and of each HAGLER BAILLY Subsidiary or their beneficiaries, or providing

     Controlled Entity.

          (c) No HAGLER BAILLY ERISA Plan which is a defined benefit pension
     plan has any "unfunded current liability", as that term is defined in
     Section 302(d)(8)(A) of ERISA, and the present fair market value of the
     assets of any such plan equals or exceeds the plan's "benefit liabilities",
     as that term is defined in Section 4001(a)(16) of ERISA, when determined
     under actuarial factors that would apply if the plan terminated in
     accordance with all applicable legal requirements. All contributions,

     completely or partially withdrawn from any Multiemployer Plan. No
     termination liability to the Pension Benefit Guaranty Corporation or
     withdrawal liability to any Multiemployer Plan that is material in the

     any Multiemployer Plan by HAGLER BAILLY or any HAGLER BAILLY Commonly
     Controlled Entity. (e) HAGLER BAILLY has made available to PHB complete

     provide any confidential information or data to any person relating to an

     advisors) that such Acquisition Proposal is reasonably capable of being
     completed, taking into account all legal, financial, regulatory and other
     aspects of the proposal and the person making the proposal, and would, if
     consummated, result in a transaction more favorable to HAGLER BAILLY's or
     PHB's stockholders, as the case may be, from a financial and strategic
     point of view than the transaction contemplated by this Agreement (any such
     more favorable Acquisition

     determines in good faith after consultation with legal counsel that such
     action is necessary for its Board of Directors to act in a manner
     consistent with its fiduciary duties under applicable law, (iii) prior to
     providing any information or data to any person in connection with an
     Acquisition Proposal by any such person, such Board of Directors receives

          (e) by either HAGLER BAILLY or PHB if the Effective Time has not
     occurred on or prior to October 31, 1998 upon giving written notice of such
     termination to the other party (unless such date shall be extended by the
     mutual written consent of the parties); provided, that the right to
     terminate this Agreement under this Section 9.1(e) shall not be available
     to any party whose breach of representations, warranties, covenants or

          (f) by HAGLER BAILLY if the Agreement shall fail to receive the
     requisite vote for approval and adoption by the stockholders of PHB at the
     PHB Stockholders' Meeting or by PHB if the issuance of shares of HAGLER
     BAILLY Common Stock in connection with the Merger shall fail to receive the
     requisite vote for approval by the stockholders of HAGLER BAILLY at the
     HAGLER BAILLY Stockholders' Meeting;

          (g) by either HAGLER BAILLY or PHB, upon five business days' prior
     notice to the other, if, as a result of a Superior Proposal received by
     such party from a person other than a party to this Agreement or any of its
     affiliates, the Board of Directors of such party determines in good faith
     that their fiduciary obligations under applicable law require that such
     Superior Proposal be accepted; provided, however, that (i) the Board of
     Directors of such party shall have concluded in good faith, after
     considering applicable provisions of law and after giving effect to all
     concessions which may be offered by the other party pursuant to clause (ii)
     below, on the basis of advice of counsel, that such action is necessary for
     such Board of Directors to act in a manner consistent with its fiduciary
     duties under applicable laws and (ii) prior to any such termination, such
     party shall, and shall cause its respective financial and legal advisors
     to, negotiate with the other party to this Agreement to make such
     adjustments in the terms and conditions of this Agreement as would enable
     such party to proceed with the transactions contemplated hereby; provided,
     however, that it shall be a condition to termination by either party
     pursuant to this Section 9.1(g) that the terminating party shall have made
     the payment of the Alternative Transaction Fee to the non-terminating party
     required by Section 9.2(b).


     SECTION 9.2. Effect of Termination.

          (a) If this Agreement is terminated pursuant to Section 9.1, this
     Agreement shall forthwith become void and there shall be no liability or
     obligation on the part of any party hereto, except that the provisions of
     Sections 6.3, 7.2, 9.2 and 11.12 shall not be extinguished but shall
     survive such termination. For any breach of a representation or warranty
     set forth in this Agreement, the sole remedy shall be termination of this
     Agreement by the non-breaching party in accordance with Sections 9.1(b) or
     9.1(c), as applicable. For any breach of any other covenant or agreement in
     this Agreement, each party shall be entitled to terminate this Agreement,
     as applicable, and shall be entitled to any remedies at law or in equity
     for such breach.

          (b) HAGLER BAILLY and PHB agree that if either party shall terminate
     this Agreement pursuant to (i) Section 9.1(f) and a Competing Transaction
     shall have been proposed publicly or been otherwise made available to at
     least a majority of the stockholders of HAGLER BAILLY or 


                                      -57-
<PAGE>

     PHB, or (ii) Section 9.1(g), then the party who is the subject of the
     Superior Proposal or Competing Transaction shall pay to the other party an
     amount equal to the sum of $10,000,000 (the "Alternative Transaction Fee").

     A "Competing Transaction" means any of the following other than the Merger:
any proposed (i) merger, consolidation, share exchange, business combination or
other similar transaction involving HAGLER BAILLY or PHB, (ii) sale, lease,
exchange transfer or other disposition directly or indirectly of 50% or more of
the consolidated assets of HAGLER BAILLY or PHB and their respective
subsidiaries, taken as a whole, or (iii) transaction in which any person shall
acquire beneficial ownership (as such term is defined in Rule 13d-3 under the
Exchange Act), or the right to acquire beneficial ownership of, or any "group"
(as such term is defined under the Securities Exchange Act of 1934, as amended)
shall have been formed which beneficially owns or has the right to acquire
beneficial ownership of, 50% or more of the outstanding voting capital stock of
HAGLER BAILLY or PHB.


     SECTION 9.3. Amendment.

     This Agreement may be amended by the parties hereto by action taken by or
on behalf of their respective Boards of Directors at any time prior to the
Effective Time; provided, however, that, after approval of this Agreement and
the Merger by the stockholders of each of PHB and HAGLER BAILLY, no amendment
may be made which would reduce the amount or change the type of consideration
into which each share of PHB Common Stock shall be converted pursuant to this
Agreement upon consummation of the Merger. This Agreement may not be amended
except by an instrument in writing signed by the parties hereto.


     SECTION 9.4. Waiver.

     At any time prior to the Effective Time, one party may:

          (a) extend the time for the performance of any of the obligations or
     other acts of the other parties,

          (b) waive any inaccuracies in the representations and warranties
     contained in this Agreement or in any document delivered pursuant to this
     Agreement of the other parties; and

          (c) waive compliance by the other party with any of the agreements or
     conditions contained in this Agreement.

     Any such extension or waiver shall be valid only if set forth in an
instrument in writing signed on behalf of such party. No delay or failure on the
part of any party hereto in exercising any right, power or privilege under this
Agreement or under any other instrument or document given in connection with or
pursuant to


                                      -58-
<PAGE>

this Agreement shall impair any such right, power or privilege or be construed
as a waiver of any default or any acquiescence therein. No single or partial
exercise of any such right, power or privilege shall preclude the further
exercise of such right, power or privilege, or the exercise of any other right,
power or privilege.

     SECTION 10.1. Survival of Special Tax Indemnity.

     The tax indemnity agreement set forth below in Section 10.2 shall survive
for a period of one year after the Effective Time (the "Claims Deadline").
Notwithstanding anything herein to the contrary, (a) any indemnity which is the
subject of a Permitted Claim (as defined below) which is asserted in writing
prior to the Claims Deadline shall survive with respect to such Permitted Claim
until the final resolution thereof and (b) the parties acknowledge and agree
that HAGLER BAILLY shall have the right to assert a claim pursuant to Section
10.2 prior to the actual incurrence of any Losses by any HAGLER BAILLY
Indemnified Person as long as such claim otherwise complies with Section
10.2(a).


     SECTION 10.2. Special Tax Indemnification; Escrow Arrangements.

     Each PHB Stockholder hereby agrees to indemnify and hold HAGLER BAILLY, the
Surviving Corporation, and any entity that is a member of an "affiliated group"
(as defined in Section 1504 of the Internal Revenue Code) that includes the
Surviving Corporation (collectively, the "HAGLER BAILLY Indemnified Persons")
harmless (but only to the extent of such PHB Stockholder's pro rata share of the
Escrow Stock) with respect to any Losses imposed upon or incurred by any HAGLER
BAILLY Indemnified Person, computed and discharged as follows:

          (a) The only Losses for which indemnification is provided pursuant to
     this Article X, and the only claims which shall constitute Permitted
     Claims, shall be those which:

               (i) are specifically attributable to Taxes of PHB and its
          Subsidiaries during any periods ending on or prior to December 31,
          1997 in excess of the Taxes actually paid by PHB and its Subsidiaries
          with respect to such periods,



                                      -59-
<PAGE>

               (ii) which result from any audit or other examination, or any
          judicial or administrative proceeding, relating to liability or
          adjustments with respect to Taxes (each referred to herein as a
          "Proceeding"):

                    (A) which is commenced prior to the Claims Deadline, or

                    (B) with respect to which the HAGLER BAILLY Indemnified
               Person receives specific notice, whether written or oral, from
               any agent or representative of a state or federal authority prior
               to the Claims Deadline, and

               (iii) for which notice is properly given by a HAGLER BAILLY
          Indemnified Person prior to the Claims Deadline in accordance with the
          provisions of Section 2.1 of the Escrow Agreement.

          (b) For the purposes of Article X, any Losses shall be reduced by any
     net tax benefit received or realized by the HAGLER BAILLY Indemnified
     Person resulting from the payment of the Taxes (and associated Losses)
     being indemnified hereunder.

          (c) The indemnification obligation of each PHB Stockholder pursuant to
     this Article X shall be several, and not joint, and the sole and exclusive
     remedy of each and every HAGLER BAILLY Indemnified Person under this
     Article X shall be to seek compensation for any and all Losses solely from
     the Escrow Stock pursuant to the terms and conditions of the Escrow
     Agreement.


                                   ARTICLE XI

Articles I (the Merger) and II (Conversion of Securities; Exchange of
Certificates), and Section 7.8 (Employees), each of which shall survive the
Effective Time indefinitely; Section 10.2 (Special Tax Indemnification), which

                                    EXHIBIT A

                            FORM OF ESCROW AGREEMENT


     THIS ESCROW AGREEMENT (the  "Agreement") is entered into this ______ day of
_____________,  1998, by and among HAGLER BAILLY,  INC., a Delaware  corporation
("Hagler Bailly");  PHB MERGER CORP., a Delaware  corporation and a wholly-owned
subsidiary of Hagler Bailly ("Merger Sub"), William Dickenson,  acting by virtue
of the Merger  Agreement (as  hereinafter  defined) as the  representative  (the
"Stockholders' Representative") of the stockholders (the "Company Stockholders")
of Putnam Hayes & Bartlett,  Inc., a Massachusetts  corporation  (the "Company")
and State Street Bank and Trust Company, a Massachusetts banking corporation, as
escrow agent (the "Escrow Agent").

     WHEREAS,  Hagler  Bailly,  Merger Sub and the Company  have entered into an
Agreement and Plan of Merger, dated as of May __, 1998 (the "Merger Agreement"),
providing  for the merger of the Company  with and into Merger Sub,  pursuant to
which the outstanding  shares of common stock,  par value $.01 per share, of the
Company  ("Company  Common Stock") will be exchanged for shares of common stock,
par value $0.01 per share, of Hagler Bailly ("Hagler Bailly Common Stock");

     WHEREAS,  capitalized  terms used but not defined  herein have the meanings
assigned to such terms in the Merger Agreement;

     WHEREAS,  Section  2.2(a)  of the  Merger  Agreement  provides  that at the
Effective  Time,  Hagler  Bailly shall deposit with the Escrow Agent One Hundred
Fifty  Thousand  (150,000) of the  aggregate  number of shares of Hagler  Bailly
Common Stock issuable to the Company  Stockholders in connection with the Merger
("Merger Stock");

     WHEREAS,  as  contemplated by Section 2.2(b) of the Merger  Agreement,  the
Stockholders'  Representative has been designated by the Company Stockholders as
their attorney-in-fact and authorized and empowered to act, for and on behalf of
any or all of the Company  Stockholders  (with full power of substitution in the
premises),  in connection with the indemnity provisions of the Merger Agreement,
this Escrow  Agreement,  and such other matters as are reasonably  necessary for
the consummation of the transactions contemplated hereby and thereby; and

     WHEREAS, the Escrow Agent is willing to act in the capacity of Escrow Agent
hereunder, subject to and upon the terms and conditions of this Agreement.

     NOW, THEREFORE, for and in consideration of the foregoing and of the mutual
covenants and agreements  hereinafter set forth, the parties hereto hereby agree
as follows:


<PAGE>


                                    ARTICLE I

                  DESIGNATION OF ESCROW AGENT AND ESCROW STOCK

     1.1  Appointment  of Escrow  Agent.  Hagler  Bailly  and the  Stockholders'
Representative  hereby designate and appoint the Escrow Agent as escrow agent to
receive,  hold and disburse the Escrow Stock (as hereinafter  defined),  and the
Escrow Agent hereby accepts such appointment and agrees to act in furtherance of
the provisions of the Merger  Agreement,  but only upon the terms and conditions
provided in this Agreement.

     1.2 Escrow Deposit.  Hagler Bailly hereby delivers to the Escrow Agent, and
the Escrow Agent hereby confirms receipt of one share certificate in the name of
the Escrow Agent,  representing the One Hundred Fifty Thousand  (150,000) shares
of Hagler  Bailly Common Stock  issuable in  accordance  with Section 2.2 of the
Merger  Agreement (the "Escrow Stock").  Schedule A hereto  identifies the name,
address  and the  percentage  interest  in the  Escrow  Stock  of  each  Company
Stockholder.

     1.3  Non-Taxable  Stock  Splits/Stock  Dividends.  Any and all  securities,
property or cash that would have been  distributed to the holders of such Escrow
Stock  as  a  result  of  any   non-taxable   stock   dividend,   stock   split,
reclassification, recapitalization, merger, business combination, consolidation,
sale of assets or  similar  transaction  shall be deemed to be Escrow  Stock and
shall be subject to the terms hereof to the same extent as the  original  Escrow
Stock.

     1.4 Voting Rights of Escrow Stock. All voting rights with respect to Escrow
Stock shall be exercised by the Company  Stockholders  in accordance  with their
proportionate  interests  therein,  and the Escrow Agent shall from time to time
execute and deliver to the Company Stockholders such proxies,  consents or other
documents as may be necessary  to enable such Company  Stockholders  to exercise
such rights and which are delivered to the Escrow Agent for execution.

     1.5 Taxable Dividends and Distributions. Any cash dividends and any taxable
stock  dividends  paid with  respect to the Escrow Stock shall be paid by Hagler
Bailly to the Company Stockholders in accordance with their respective interests
in the Escrow Stock and shall not be subject to the terms of this Agreement.

     1.6 Value of Escrow Stock.  For all purposes of this  Agreement,  including
without  limitation the distribution of Escrow Stock, the value of each share of
Escrow Stock shall be equal to the reported  closing  price of a share of Hagler
Bailly Common Stock on the Nasdaq National Market on the day prior to the Merger
Date (the "Hagler Bailly Closing Price"), as such Hagler Bailly Closing Price is
certified  to  the  Escrow  Agent  by the  Stockholder  Representative  and  the
authorized representative of the Hagler Bailly.


                                      -2-

     1.7 Liabilities Covered. The Agreement has been executed and the deposit of
the Escrow Stock  hereunder has been made pursuant to Section 2.2 and Section 10
of the Merger  Agreement.  The deposit of the Escrow Stock has been made for the
purpose of funding and securing, to the extent of the value of the Escrow Stock,
the  indemnities  set  forth in  Article  X of the  Merger  Agreement  until the
expiration of the Claims Deadline or as otherwise provided herein.

                                   ARTICLE II

                       DELIVERY OF ESCROW STOCK FOR CLAIMS

     2.1 Claims Against Escrow Stock.

     (a) If at any time on or prior to 5:00 p.m.,  Arlington,  Virginia time, on
the first anniversary of the Effective Time (as defined in the Merger Agreement)
(the "Claims  Deadline"),  Hagler  Bailly (on its own behalf or on behalf of any
other Hagler Bailly Indemnified Person) shall assert a claim for indemnification
pursuant to Article X of the Merger Agreement for Losses, then Hagler Bailly may
submit to the Escrow  Agent and to the  Stockholders'  Representative  a written
claim (a  "Claim  Notice")  signed by an  executive  officer  of  Hagler  Bailly
stating:  (i) that a claim for indemnification has been made by Hagler Bailly in
accordance with Article X of the Merger Agreement;  (ii) the number of shares of
Escrow Stock to which such Hagler  Bailly  Indemnified  Person is entitled  with
respect to such Losses  determined  by dividing  the amount of Losses  specified
therein by the Hagler  Bailly Share  Price;  and (iii) that a copy of such Claim
Notice has been delivered to the Stockholders' Representative in accordance with
Section 6.4 of this Agreement. In no event shall any Escrow Stock be distributed
to Hagler Bailly (i) until the Claim Notice has been resolved in accordance with
Section 2.2 below and (ii) Losses related to the Claim Notice have been incurred
by a Hagler Bailly Indemnified Person.

     (b) Upon  receipt of a Claim  Notice,  the Escrow  Agent  shall send a copy
thereof  by  a  nationally   recognized   overnight   delivery  service  to  the
Stockholders' Representative at the address for notices set forth in Section 6.4
of this Agreement.

     2.2 Resolution of Asserted Claims. If the Stockholders' Representative does
not deliver to the Escrow Agent a written notice (a "Response Notice") objecting
to the  delivery of all or any portion of the Escrow  Stock to Hagler  Bailly as
specified  in a Claim  Notice  within  twenty (20) days after the  Stockholders'
Representative's  receipt of such Claim  Notice,  then the Escrow  Agent  shall,
after the  expiration  of such twenty (20) day  period,  immediately  deliver to
Hagler  Bailly  the  number of shares of Escrow  Stock  specified  in such Claim
Notice with respect to which the Stockholders'  Representative  did not submit a
Response Notice. Each Response Notice shall state in reasonable detail the basis
upon which the Company  Stockholders  dispute the Claim Notice and the number of
shares of Escrow Stock


                                      -3-
<PAGE>


stated  in the  Claim  Notice  that the  Company  Stockholders  object  to being
delivered to Hagler Bailly.

     2.3  Resolution  of  Disputed   Claims   Against   Escrow  Stock.   If  the
Stockholders'  Representative  delivers to the Escrow Agent a Response Notice at
any time on or prior to twenty (20) days after the Escrow  Agent's  receipt of a
Claims Notice,  then the Escrow Agent shall not make any payment or distribution
of the Escrow  Stock  contested  in such  Response  Notice  unless and until the
Escrow Agent shall have received either:  (a) a certificate  signed on behalf of
the Hagler Bailly and the Stockholders' Representative certifying the resolution
of the amount of the asserted  claim for Losses and  directing the delivery of a
specified  number  of  shares  of  Escrow  Stock  to  which  the  Hagler  Bailly
Indemnified Person is entitled with respect to such amount; (b) a certified copy
of a  final,  binding  and  nonappealable  judgment  of  a  court  of  competent
jurisdiction  determining the amount of the asserted claim for Losses in dispute
and  directing  delivery  of  shares  of  Escrow  Stock  to  the  Hagler  Bailly
Indemnified Person; or (c) a certified copy of an award of an arbitrator,  under
an arrangement  providing for no appeal,  determining the amount of the asserted
claim for Losses in dispute.  Upon receipt of any such certification,  the claim
for Losses shall be treated as a resolved  undisputed claim and the Escrow Agent
shall present to the Hagler Bailly's  transfer agent (the "Transfer  Agent") the
Escrow  Certificate  and shall  obtain from the  Transfer  Agent in  replacement
thereof certificates (a) in the name of the Hagler Bailly Indemnified Person and
(b) in the name of the  Escrow  Agent and shall  deliver  to the  Hagler  Bailly
Indemnified  Person the certificate  representing the number of shares of Escrow
Stock to which the Hagler Bailly  Indemnified Person is entitled with respect to
such Losses in accordance with and pursuant to such certification (in all cases,
to be  determined  by dividing  the amount of such  Losses by the Hagler  Bailly
Closing Price (subject to the provisions of Section 2.1)).

                                   ARTICLE III

                          DISTRIBUTION OF ESCROW STOCK
                        UPON TERMINATION OF THE AGREEMENT

     3.1 Deadline for Claims and Termination.  Hagler Bailly or any other Hagler
Bailly  Indemnified Person shall not be entitled to assert any claim against the
Escrow Stock after the Claims Deadline;  provided,  however, that any claim made
in writing  on or prior to the  Claims  Deadline  (whether  or not formal  legal
action  shall yet have been  commenced  based upon such claim and whether or not
Losses have actually been incurred) shall continue,  subject to final resolution
as provided herein and in the Merger  Agreement.  This Agreement shall terminate
upon  complete  distribution  of  the  Escrow  Stock  in  accordance  with  this
Agreement.



                                      -4-

     3.2 Distribution of the Escrow Stock upon Termination.

     (a) On the first business day after the Claims  Deadline,  the Escrow Agent
shall deliver to the Transfer Agent the certificate  representing  the shares of
Escrow Stock and a notice  designating  the number of shares of Escrow Stock not
previously  distributed  or  otherwise  subject to claims  pursuant to Section 2
hereof and each  Company  Stockholder's  interest in that  portion of the Escrow
Stock in  accordance  with the  percentages  set forth in Schedule A. The Escrow
Agent  shall  obtain  from the  Transfer  Agent  in  replacement  thereof  stock
certificates  in the name of each Company  Stockholder  duly  endorsed by Hagler
Bailly,  representing each Company Stockholder's  interest in such Escrow Stock,
and a certificate  in the name of the Escrow Agent  representing  the balance of
Escrow Stock to be held in escrow, if any, duly endorsed by Hagler Bailly.  Upon
receipt of the replacement  stock  certificates,  the Escrow Agent shall deliver
the stock  certificates to the Stockholders'  Representative for distribution to
each  Company  Stockholder.  Thereafter,  the balance of the Escrow  Stock shall
continue  to be held by the Escrow  Agent in  accordance  with the terms of this
Agreement until all claims  asserted  against the Escrow Stock have been finally
resolved  in  accordance  with  Section 2 hereof,  whereupon  the balance of the
Escrow Stock (remaining after  satisfaction of such claims) shall be distributed
to the Company Stockholders as provided in this Section 3.2(a) in full discharge
of the Escrow Agent's obligations under this Agreement.

     (b)  Notwithstanding  the  foregoing,  in the event that,  under any of the
provisions  contained  herein,  the Escrow  Agent  would be  required to deliver
fractional  interests  in shares of Hagler  Bailly  Common  Stock to the Company
Stockholders,  Hagler Bailly shall purchase from the Escrow Agent that number of
shares of Escrow Stock (or fractional  interests  therein) as shall be necessary
to eliminate such fractional interests,  at a purchase price equal to the Hagler
Bailly Closing Price.  In such event,  the Escrow Agent shall  distribute to the
Company  Stockholders  who would  otherwise  have been  entitled  to  fractional
interests in shares of Hagler Bailly Common Stock,  the cash  equivalent of such
fractional  shares based on a purchase  price equal to the Hagler Bailly Closing
Price. Any such cash received shall not be invested by the Escrow Agent.

                                   ARTICLE IV

                   RESPONSIBILITIES AND DUTIES OF ESCROW AGENT

     4.1 Rights, Duties,  Liabilities and Immunities of Escrow Agent. The duties
and obligations of the Escrow Agent shall be determined solely by the provisions
of this Agreement, and the Escrow Agent shall be under no obligation to refer to
any other  documents  between  or among the  parties  related in any way to this
Agreement  except for any documents  referenced  herein,  it being  specifically


                                      -5-
<PAGE>


understood that the following  provisions of this Article IV are accepted by all
parties hereto.

     (a) The Escrow  Agent shall be  entitled to rely upon any order,  judgment,
certificate,  demand, notice, instrument,  opinion or other writing delivered to
it  hereunder  without  being  required to  determine  the  authenticity  or the
correctness of any fact stated therein,  any signature  thereon or the propriety
or validity of the service thereof (and claims made therein).

     (b) The Escrow Agent may act in reliance  upon any  instrument or signature
believed by it to be genuine and may assume that any person  purporting  to give
notice or receipt or advice or make any  statement  or execute  any  document in
connection with the provisions hereof has been duly authorized to do so.

     (c) The Escrow  Agent  shall not be liable for any error of judgment or for
any act done or step taken or omitted by it in good faith or for any  mistake of
fact or law or for any thing which it may do or refrain from doing in connection
herewith,  except  due to the Escrow  Agent's  own gross  negligence  or willful
misconduct.

     (d) The Escrow Agent may consult with and obtain  advice from legal counsel
(which may be in-house  counsel)  in the event of any  question as to any of the
provisions of this Agreement or its duties hereunder, and the Escrow Agent shall
incur no  liability  and shall be fully  protected  in  acting in good  faith in
accordance  with the opinion and  instructions  of such counsel.  Subject to the
provisions of Section 4.3 hereof,  the cost of such  services  shall be added to
and shall become a part of the Escrow Agent's compensation hereunder.

     (e) The Escrow Agent shall have no duties except those  expressly set forth
herein,  and shall not be bound by any notice of a claim or demand with  respect
thereto, or any waiver,  modification,  amendment,  termination or rescission of
this  Agreement,  unless in a writing  received by it, and, if its duties herein
are affected, unless it shall have given its prior written consent thereto.

     (f) The  Escrow  Agent  is not a party to and is not  bound  by the  Merger
Agreement,  nor is it a party to or bound by or charged with notice of any other
agreement  (other than this Agreement) out of which the Escrow Stock might arise
or to which  they may  relate.  The  Escrow  Agent  is not  responsible  for the
recitals  appearing  in this  Agreement.  The  recitals  shall be  deemed  to be
statements of the Hagler Bailly and the Company.

     (g) In the event of any  disagreement  between  any of the  parties to this
Agreement or between them or any one of them and any other person,  resulting in
adverse  claims or demands being made in connection  with the subject  matter of
this Agreement, or in the event the Escrow Agent in good faith shall be in doubt
as to what action it should take  hereunder,  the Escrow  Agent shall  thereupon


                                      -6-
<PAGE>


have the right (i) to refrain from complying with any claims or demands asserted
on it as the Escrow Agent or (ii) to refuse to take any other action  hereunder,
so long as such disagreement  continues or exists, and in either such event, the
Escrow  Agent  shall not be or become  liable in any way to any  person  for the
Escrow  Agent's  failure  to act,  and the Escrow  Agent  shall be  entitled  to
continue to refrain from acting, until the rights of all parties shall have been
fully and finally resolved and the Escrow Agent shall have been notified thereof
by a writing  signed by all such  persons.  The rights of the Escrow Agent under
this  subsection (g) are cumulative of all other rights which it may have by law
or otherwise.  The Escrow Agent may, but shall be under no duty  whatsoever  to,
institute or defend any legal proceedings which relate to the Escrow Fund.

     (h) Hagler  Bailly  hereby  agrees to  indemnify  the Escrow  Agent and its
officers,  directors,  employees and agents for, and hold them harmless against,
any loss,  liability or expense  incurred  without  gross  negligence or willful
misconduct on the part of the Escrow Agent arising out of or in connection  with
its  entering  into  this  Agreement  and  carrying  out its  duties  hereunder,
including  costs and expenses of  defending  itself from any claims of liability
with respect thereto.  This Section 4.1(h) shall survive the termination of this
Agreement and the resignation of the Escrow Agent.

     4.2 Copies of  Certifications,  Notices and Other  Documentation.  Promptly
after  receipt by the  Escrow  Agent from the  Stockholders'  Representative  or
Hagler Bailly of any written  certificate,  notice,  request,  waiver,  consent,
receipt or other document (other than a Claims Notice or Response  Notice),  the
Escrow  Agent  shall  furnish a copy of any of such  items to the  Stockholders'
Representative  or Hagler Bailly, as the case may be. Upon receipt by the Escrow
Agent of the Escrow Stock to be held in escrow pursuant to this  Agreement,  the
Escrow  Agent shall  deliver a written  receipt  therefor  to Hagler  Bailly and
Stockholders' Representative.

     4.3  Compensation.  The Escrow Agent undertakes to perform all duties which
are  expressly  set forth  herein  for the fee set forth in  Schedule B attached
hereto.  The fee shall be payable upon execution of this  Agreement.  The Escrow
Agent shall also be  entitled  to  reimbursement  for all  reasonable  expenses,
disbursements  and advances  incurred or made by the Escrow Agent in  accordance
with  any  of  the  provisions  of  this  Agreement  (including  the  reasonable
compensation  and the  expenses  and  disbursements  of its counsel  (other than
in-house  legal  counsel)  and of all  persons  not  regularly  in its  employ),
exclusive of any such expense,  disbursement  or advance that may arise from its
own  gross  negligence  or  willful   misconduct.   All  such  compensation  and
reimbursement of the Escrow Agent under the provisions of this Section 4.3 shall
be paid by Hagler Bailly.

     4.4  Successor  Escrow Agent.  The Escrow Agent (and any  successor  Escrow
Agent) may at any time resign by giving  notice in writing to the  Stockholders'
Representative  and the Hagler Bailly,  and the Escrow Agent shall be discharged
from


                                      -7-
<PAGE>


its  duties  hereunder  upon the  appointment  of a  successor  Escrow  Agent as
hereinafter provided.  In the event of any such resignation,  a successor Escrow
Agent shall be appointed by written consent of the Stockholders'  Representative
and the Hagler  Bailly;  provided if no such  successor is so  appointed  within
thirty (30) days of the Escrow Agent's  resignation,  the Escrow Agent may apply
to a court  of  competent  jurisdiction  for  appointment  of a  successor.  Any
successor  Escrow Agent shall deliver to the  Stockholders'  Representative  and
Hagler Bailly a written  instrument  accepting the  appointment  hereunder,  and
thereupon  it shall  succeed to all the  rights  and duties of the Escrow  Agent
hereunder  and  shall  be  entitled  to  receive  all  assets  then  held by the
predecessor Escrow Agent hereunder.

                                    ARTICLE V

                        THE STOCKHOLDERS' REPRESENTATIVE

     5.1.   Appointment   and  Successor   Stockholders'   Representative.   The
Stockholders'  Representative  has been  appointed as the initial  Stockholders'
Representative  and in such capacity  shall act as  representative  and agent of
each of the Company  Stockholders  in connection  with this  Agreement.  If such
Stockholders'  Representative shall resign,  become disabled or die, a successor
Stockholders' Representative (and, if necessary, further successor Stockholders'
Representatives),  shall  be  appointed  by  a  majority  vote  of  the  Company
Stockholders.

     5.2.  Responsibility;  Indemnification.  The  Stockholders'  Representative
shall have no liability to the Company  Stockholders  with respect to any action
taken  by  him  or  her  under  this  Agreement,  except  with  respect  to  the
Stockholders'    Representative's   fraud   or   intentional   misconduct.   The
Stockholders'  Representative  shall not be liable to any Company Stockholder in
the event that in the exercise of the Stockholders'  Representative's reasonable
judgment he believes there will not be adequate resources available to cover his
potential  costs  and  expenses  to  contest a claim  made by an  Hagler  Bailly
Indemnified  Person  hereunder.  The  Stockholders'  Representative  may  act in
reliance  upon the advice of counsel in  reference  to any matter in  connection
with this  Agreement  and shall not  incur any  liability  to the other  Company
Stockholders  or any one of  them,  for  any  action  taken  in  good  faith  in
accordance with such advice. The Company  Stockholders hereby agree to indemnify
the  Stockholders'  Representative,  ratably  according  to their  proportionate
interests  in the  Escrow  Stock,  from  and  against  any and all  liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
expenses or disbursements of any kind or nature  whatsoever which may be imposed
on, incurred by or asserted against any Stockholders'  Representative in any way
relating to or arising out of this Agreement,  or any action taken or omitted to
be taken by any  Stockholders'  Representative  under this Agreement;  provided,
however,  that no Company  Stockholder  shall be liable for any  portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs,


                                      -8-
<PAGE>


expenses  or   disbursements   if  the  same  results  from  the   Stockholders'
Representative's fraud or intentional misconduct.

     5.3 Indemnification of Stockholders'  Representative.  Hagler Bailly hereby
agrees to indemnify and hold the Stockholders'  Representative harmless from and
against any and all liabilities and Losses of the  Stockholders'  Representative
arising out of or incurred in  connection  with any claims,  demands or suits by
any Company Stockholder,  whether asserted,  unasserted,  absolute,  contingent,
known or unknown,  against the Stockholders'  Representative  resulting from his
duties as  Stockholders'  Representative,  except for any liabilities and Losses
that  result  from  the  Stockholders'  Representative's  fraud  or  intentional
misconduct.

                                   ARTICLE VI

                                  MISCELLANEOUS

     6.1 Successors and Assigns.  This Agreement shall be binding upon and shall
inure  to  the  benefit  of  the  Company   Stockholders  (by  and  through  the
Stockholders'  Representative),  Hagler Bailly, Merger Sub and the Escrow Agent,
and their respective successors and assigns, whether so expressed or not.

     6.2  Modification;   Waiver.  This  Agreement  may  be  amended,  modified,
superseded or canceled, and any of the terms or conditions hereof may be waived,
only by a written instrument  executed by each party hereto, or in the case of a
waiver, by the party waiving compliance.  No failure or delay on the part of any
party  hereto in  exercising  any power or right  hereunder  shall  operate as a
waiver  thereof,  nor shall any single or partial  exercise of any such right or
power, or any abandonment or  discontinuance of steps to enforce such a right or
power,  preclude  any other or further  exercise  thereof or the exercise of any
other  right or power.  The rights and  remedies of the  parties  hereunder  are
cumulative  and not  exclusive  of any  rights  or  remedies  which  they  would
otherwise  have. No  modification  or waiver of any provision of this Agreement,
nor  consent  to any  departure  by any party  therefrom,  shall in any event be
effective  unless the same shall be in writing,  and then such waiver or consent
shall be effective  only in the specific  instance and for the purpose for which
given.  No notice to or demand on any party in any case shall entitle such party
to any other or further notice or demand in similar or other circumstances.

     6.3  Captions.  The  Article  and  Section  captions  used  herein  are for
reference  purposes  only  and  shall  not in any  way  affect  the  meaning  or

                                    EXHIBIT B

                      FORM OF REGISTRATION RIGHTS AGREEMENT

     THIS REGISTRATION  RIGHTS AGREEMENT (this "Agreement") is entered into this
_____ day of _________,  1998, by and between  HAGLER  BAILLY,  INC., a Delaware
corporation  ("HAGLER  BAILLY"),  and the  undersigned  stockholders  (the  "PHB
Stockholders") of PUTNAM,  HAYES & BARTLETT,  INC., a Massachusetts  corporation
("PHB").

     WHEREAS,  on or about the date hereof,  the PHB  Stockholders  have or will
have  become the owners of shares of HAGLER  BAILLY's  common  stock,  par value
$0.01 per share ("HAGLER BAILLY Common Stock");

     WHEREAS, as part of the inducement for the parties hereto to enter into and
perform the Agreement and Plan of Merger (the "Merger  Agreement"),  dated as of
June ___,  1998,  the parties hereto have agreed to enter into this Agreement in
order to provide,  among other things, for certain  registration and "tag-along"
rights;

     NOW, THEREFORE,  the parties hereto, in consideration of the foregoing, the
mutual  covenants  and  agreements  hereinafter  set  forth,  and other good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  hereby  are
acknowledged, agree as follows:

          1. Term.  This Agreement  shall terminate on the date on which the PHB
     Stockholders could sell all of their Registerable  Securities to the public
     in a single  transaction  pursuant to the  provisions of Rule 144 under the
     Securities  Act,  provided,  however,  the  indemnification  provisions  of
     Section 6 hereof shall survive the termination of this Agreement.

          2. Piggyback Registration Rights.

          (a)  If at  any  time  or  times  HAGLER  BAILLY  proposes  to  make a
     registered  public  offering of any of its securities  (whether for its own
     account or for the  account of others)  under the  Securities  Act,  HAGLER
     BAILLY shall (i) promptly give written notice of the proposed  registration
     to each of the PHB  Stockholders  (such  notice to  include  the  number of
     shares HAGLER BAILLY or other security  holders propose to register and, if
     known, the name of the proposed  underwriter) and (ii) use its best efforts
     to include in such registration (and any related  qualification  under Blue
     Sky laws and/or other compliance) all the Registerable Securities specified
     in a written request or requests made by any PHB Stockholder within 30 days
     after  the  receipt  of  such  notice  from  HAGLER  BAILLY  (a  "Piggyback
     Registration").  Such  written  request  may  specify  all or a  part  of a


<PAGE>


     holder's Registerable Securities, provided, however, that (x) HAGLER BAILLY
     will  not  be  required  to  effect  a  Piggyback  Registration  if  it  is
     registering  securities  on Forms  S-8 or S-4 (or any  successor  forms) or
     another SEC  registration  form not  suitable  for  inclusion  of shares of
     selling  stockholders  for offer to the public,  and (y) HAGLER  BAILLY may
     withdraw any  proposed  registration  statement  or offering of  securities
     under this Section 2 at any time without  liability to any PHB Stockholder,
     in which case HAGLER BAILLY will not be required to effect a registration.

          (b)  If  a  Piggyback   Registration   is  an   underwritten   primary
     registration  on behalf  of HAGLER  BAILLY,  and the  managing  underwriter
     advises HAGLER BAILLY in writing that in the managing underwriter's opinion
     the number of  securities  requested  to be included  in such  registration
     exceeds  the number  that can be sold in such  offering  without  adversely
     affecting the marketability of the offering, HAGLER BAILLY shall include in
     such offering first, the securities of HAGLER BAILLY proposed to be sold by
     HAGLER BAILLY and second,  all other  securities held by security  holders,
     including  the  Registerable  Securities,  requested to be included in such
     registration   by  all   other   security   holders   (including   the  PHB
     Stockholders),  pro rata among such security holders, based upon the number
     of shares  requested  by each to be  included  in such  registration.  If a
     Piggyback Registration is an underwritten primary registration on behalf of
     HAGLER  BAILLY,  the selling PHB  Stockholders  agree to sell their  HAGLER
     BAILLY Common Stock, if HAGLER BAILLY so requests, on the same basis as the
     other  securities  included  in such  registration  are being  sold and the
     underwriter  or  underwriters  for such  registration  shall be selected by
     HAGLER BAILLY.  If a Piggyback  Registration is an  underwritten  secondary
     registration   on  behalf  of  selling   stockholders,   and  the  managing
     underwriter   advises  HAGLER  BAILLY  in  writing  that  in  the  managing
     underwriter's  opinion the number of securities requested to be included in
     such  registration  exceeds  the number  that can be sold in such  offering
     without adversely affecting the marketability of the offering,  then HAGLER
     BAILLY shall  include in such  offering  the  securities  of HAGLER  BAILLY
     proposed to be sold by such selling  stockholders  and all other securities
     held by security holders (including the Registerable  Securities) requested
     to  be  included  in  such  registration  by  all  other  security  holders
     (including  the  PHB  Stockholders),   pro  rata  among  all  such  selling
     stockholders  and other security  holders,  based upon the number of shares
     requested to be included in such registration.

          3. Demand Registration Rights.

          (a) At any time  after  one (1) year  from the  effective  date of the
     Merger,  if HAGLER BAILLY has not made a registered  public offering of any
     of its securities which is a Piggyback  Registration  under this Agreement,
     then  the PHB  Stockholders  shall  collectively  be  entitled  to  request
     registration  for  sale  under  the  Securities  Act of  their  Registrable
     Securities  (a "Demand  Registration"),  and



                                     - 2 -
<PAGE>


     HAGLER BAILLY agrees to keep  effective for two (2) years,  a  registration
     statement on Form S-1 or S-3; provided,  however,  that HAGLER BAILLY shall
     (i) not be obligated to effect a Demand  Registration unless the holders of
     at least fifty  percent  (50%) of the  Registerable  Securities  shall have
     requested such demand registration and (ii) only be obligated to effect one
     (1) Demand Registration.

          (b)  A  Demand  Registration  shall  be  deemed  to  occur  when  such
     registration  becomes  effective  under the Securities Act, except that if,
     after it becomes effective,  such Demand Registration is interfered with by
     any stop order,  injunction or other order or requirement of the SEC or any
     other governmental authority, such registration shall not be deemed to have
     been effected unless such stop order,  injunction or other order shall have
     been subsequently vacated or removed.

          (c) HAGLER BAILLY may postpone a Demand  Registration  for one or more
     periods  not to exceed  six (6)  months  in  aggregate  if (i) such  Demand
     Registration would require an audit of HAGLER BAILLY's financial statements
     at a time such  audit  would not  otherwise  be  required  pursuant  to the
     Exchange Act;  (ii) the Board of Directors of HAGLER  BAILLY  determines in
     good faith  that  HAGLER  BAILLY  would be  required  to  disclose  in such
     registration  statement  information  which HAGLER BAILLY has not otherwise
     made public and would not otherwise be required to make public at that time
     pursuant  to the  Exchange  Act,  and that it is in the best  interests  of
     HAGLER  BAILLY not to disclose  such  information  at such time;  (iii) the
     Board of  Directors  of HAGLER  BAILLY  determines  in good  faith that the
     Demand   Registration   would   interfere   with  any  pending   financing,
     acquisition,  corporate  reorganization or any other corporate  development
     involving  HAGLER BAILLY or any of its  subsidiaries;  (iv) within the last
     360 days (180 days if HAGLER  BAILLY  is  eligible  to file a  registration
     statement  with  the  SEC  on  Form  S-3)  HAGLER  BAILLY  has  effected  a
     registration  of its  securities  pursuant  to which  the PHB  Stockholders
     requesting the  registration  could have exercised  Piggyback  Registration
     rights to sell  their  Registrable  Securities;  or (v)  within the 90 days
     immediately  preceding a request for a Demand  Registration,  HAGLER BAILLY
     has effected any other registration of its securities.

          (d) In  the  event  that  a  Demand  Registration  is an  underwritten
     registration,   HAGLER  BAILLY  shall  select  a  managing  underwriter  or
     underwriters for such Demand  Registration  reasonably  satisfactory to the
     holders of a majority  of the  Registrable  Securities  to be included in a
     Demand Registration pursuant to this Section 3.

          (e) Once HAGLER BAILLY files a registration  statement with respect to
     Registrable  Securities  pursuant  to  this  Section  3,  so  long  as such
     registration  has not been withdrawn or abandoned at the request of the PHB
     Stockholders, HAGLER BAILLY will not file or cause to be effected any other
     registration of any of its equity  securities or securities  convertible or
     exchangeable



                                     - 3 -

     into or  exercisable  for its equity  securities  under the  Securities Act
     (except on Form S-8 or Form S-4 or any successor form),  whether on its own
     behalf or at the request of any holder or holders of such securities, until
     a  period  of at least  90 days  after  the  earlier  of (i) the date  such
     registration  statement  filed  pursuant  to this  Section  3 ceases  to be
     effective  or (ii) the date that all shares  registered  therein  have been
     sold.

          4. Registration Procedures.

          (a) HAGLER  BAILLY  shall have no  obligation  to file a  registration
     statement for a Demand Registration,  or to include Registerable Securities
     owned by the PHB  Stockholders in a registration  statement for a Piggyback
     Registration,  unless  and until the PHB  Stockholders  have  furnished  to
     HAGLER BAILLY all information and statements about or pertaining to the PHB
     Stockholders  in such  reasonable  detail  and on such  timely  basis as is
     reasonably  deemed by HAGLER BAILLY to be necessary or appropriate  for the
     preparation of the registration statement.

          (b) Whenever the PHB  Stockholders  have requested  that  Registerable
     Securities   be   registered   in  a  Demand   Registration   or  Piggyback
     Registration,  HAGLER  BAILLY  shall keep each PHB  Stockholder  advised in
     writing as to the initiation of each  registration and as to the completion
     thereof. As expeditiously as reasonably possible, HAGLER BAILLY shall:

               (1) prepare and file with the SEC a  registration  statement with
          respect to such  Registerable  Securities and use its reasonable  best
          efforts,  (subject  to Section  2(a)(y)  with  respect to a  Piggyback
          Registration) to cause such registration statement to become effective
          (provided that before filing a registration statement or prospectus or
          any amendments or supplements  thereto,  HAGLER BAILLY will furnish to
          one counsel  selected by the holders of a majority of the Registerable
          Securities  covered by such registration  statement copies of all such
          documents proposed to be filed, which documents will be subject to the
          review of such counsel);

               (2) keep such  registration  statement  effective for a period of
          not  less  than  two (2)  years or  until  the PHB  Stockholders  have
          completed the distribution  described in such registration  statement,
          whichever  occurs  first,  and amend or supplement  such  registration
          statement and the  prospectus  contained  therein from time to time to
          the extent  necessary to comply with the  provisions of the Securities
          Act  and  applicable   state  securities  laws  with  respect  to  the
          disposition of all securities  covered by such registration  statement
          during  such  period  in  accordance  with  the  intended  methods  of
          disposition  by the  sellers  thereof  set forth in such  registration
          statement;

               (3) furnish to the PHB  Stockholders the number of copies of such
          registration  statement,  each amendment and supplement  thereto,  the



                                     - 4 -
<PAGE>


          prospectus  contained in such registration  statement  (including each
          preliminary   prospectus),   and  such  other  documents  as  the  PHB
          Stockholders from time to time may reasonably request;

               (4) use its best efforts to register or qualify such shares under
          the  state  blue  sky  or   securities   ("Blue  Sky")  laws  of  such
          jurisdictions as any PHB Stockholder  reasonably  requests,  and to do
          any and all other acts and things that may be reasonably  necessary or
          advisable to enable the PHB Stockholders to consummate the disposition
          of such shares in such jurisdictions;  provided,  however, that HAGLER
          BAILLY will not be required  to do any of the  following:  (i) qualify
          generally to do business in any  jurisdiction  where it is not then so
          qualified  or  otherwise  required  to be so  qualified  but for  this
          Section  4(b),  or (ii) take any action which would  subject it to the
          service of process in  actions  other than those  arising  out of such
          registration;

               (5) notify the PHB  Stockholders,  at any time when a  prospectus
          relating to the  Registerable  Securities  is required to be delivered
          under the  Securities  Act, of the occurrence of any event as a result
          of which the prospectus  included in any such  registration  statement
          contains an untrue  statement  of a material  fact or omits to state a
          material fact  required to be stated  therein or necessary to make the
          statements therein in the light of the circumstances  under which they
          were  made,  not  misleading,  and  prepare  and  furnish  to such PHB
          Stockholders  a  reasonable  number  of  copies  of  a  supplement  or
          amendment to the prospectus as may be necessary so that, as thereafter
          delivered to the purchasers of such shares,  the  prospectus  will not
          contain an untrue  statement  of a material  fact or omit to state any
          fact required to be stated therein or necessary to make the statements
          therein,  in  the  light  of  the  circumstances  then  existing,  not
          misleading;

               (6) cause all such  Registerable  Securities to be listed on each
          securities  exchange  on which  similar  securities  issued  by HAGLER
          BAILLY are then  listed  and,  if not so  listed,  to be listed on the
          National   Association  of  Securities   Dealers  ("NASD")   Automated
          Quotation  ("Nasdaq") system and, if listed on the Nasdaq system,  use
          its  reasonable  best  efforts  to  secure  designation  of  all  such
          Registerable  Securities  covered by such registration  statement as a
          Nasdaq  "national  market system  security" within the meaning of Rule
          11Aa2-1 of the SEC or,  failing that,  to secure Nasdaq  authorization
          for such Registerable Securities;

               (7)  provide  a  transfer   agent  and  registrar  for  all  such
          Registerable  Securities  (if HAGLER BAILLY does not already have such
          an  agent)  not later  than the  effective  date of such  registration
          statement;

               (8) enter into such customary agreements (including  underwriting
          agreements  in customary  form) and take all such other actions as the
          holders of a majority of the Registerable Securities being sold or the
          underwriters,  if any,  reasonably  request  in order to  expedite  or
          facilitate the disposition of such



                                     - 5 -
<PAGE>


          Registerable  Securities (including,  without limitation,  effecting a
          stock split or a combination of shares);

               (9) make  available all financial  and other  records,  pertinent
          corporate documents and properties of HAGLER BAILLY for inspection by,
          and  cause  HAGLER  BAILLY's   officers,   directors,   employees  and
          independent accountants to supply all information reasonably requested
          by,   any  seller  of   Registerable   Securities,   any   underwriter
          participating  in  any  disposition   pursuant  to  such  registration
          statement and any attorney,  accountant or other agent retained by any
          such  seller or  underwriter  in  connection  with  such  registration
          statement who executes any reasonable  confidentiality  agreement that
          may be  reasonably  requested  by  HAGLER  BAILLY  or who is  bound by
          fiduciary  duty  or  professional   responsibility   to  preserve  the
          confidentiality thereof;

               (10) otherwise use its reasonable best efforts to comply with all
          applicable rules and regulations of the SEC, and make available to its
          security  holders,  as soon as  reasonably  practicable,  an  earnings
          statement covering the period of at least 12 months beginning with the
          first day of HAGLER  BAILLY's  first full  calendar  quarter after the
          effective date of the registration statement, which earnings statement
          shall satisfy the  provisions of Section 11(a) of the  Securities  Act
          and Rule 158 thereunder; and

               (11) use its reasonable  best efforts to cause such  Registerable
          Securities  covered by such  registration  statement to be  registered
          with or approved by such other governmental agencies or authorities as
          may be  necessary  to enable the  sellers  thereof to  consummate  the
          disposition of such Registerable Securities.

          5. Holdback Agreements.

          (a) Each  holder of  Registerable  Securities  who is  included in the
     Registration Statement agrees not to effect any public sale or distribution
     (including  sales  pursuant  to Rule  144) of equity  securities  of HAGLER
     BAILLY,  or any securities  convertible into or exchangeable or exercisable
     for such  securities,  during the seven days prior to and the 90-day period
     beginning on the effective date of any underwritten  Demand Registration or
     any   underwritten   Piggyback   Registration   (except  as  part  of  such
     underwritten registration), unless the underwriters managing the registered
     public offering otherwise agree.

          (b)  HAGLER  BAILLY  agrees  (i)  not to  effect  any  public  sale or
     distribution of its equity securities,  or any securities  convertible into
     or exchangeable or exercisable for such  securities,  during the seven days
     prior to and during the 90-day period  beginning on the  effective  date of
     any  underwritten  Demand   Registration  or  any  underwritten   Piggyback
     Registration (except as part of such underwritten  registration or pursuant
     to registrations on Form S-8 or Form S-4 or any successor form), unless the
     underwriters  managing the registered public offering  otherwise agree, and
     (ii) to use all  reasonable  efforts to cause each Person



                                     - 6 -
<PAGE>


     that,  during the 30-day period prior to the effective  date of such Demand
     Registration  or  Piggyback  Registration,  holds  shares of HAGLER  BAILLY
     Common Stock (or securities convertible into or exercisable or exchangeable
     for HAGLER BAILLY  Common  Stock)  received from HAGLER BAILLY in an amount
     which,  on a fully diluted basis,  exceeds 1% of HAGLER BAILLY Common Stock
     then  outstanding  (on a fully diluted  basis),  to agree not to effect any
     public sale or distribution  (including  sales pursuant to Rule 144) of any
     such  securities  during such period  (except as part of such  underwritten
     registration, if otherwise permitted), unless the underwriters managing the
     registered public offering otherwise agree.

          6. Tag-Along Rights.

          If at any time  HAGLER  BAILLY  arranges  for a sale of HAGLER  BAILLY
     Common Stock by security holders in a private placement  transaction,  then
     HAGLER  BAILLY  shall  provide  the PHB  Stockholders  with  notice  and an
     opportunity  to  participate in such intended sale on a pro rata basis with
     the other selling security holders.

          7. Registration Expenses.

          (a)  If  Registerable   Securities  are  included  in  a  registration
     statement for a Demand  Registration or Piggyback  Registration,  then each
     selling PHB Stockholder  shall pay all transfer taxes, if any,  relating to
     the sale of its shares,  the fees and expenses of its own counsel,  and its
     pro rata  portion  of any  underwriting  discounts  or  commissions  or the
     equivalent thereof.

          (b)  If  Registerable   Securities  are  included  in  a  registration
     statement for a Demand Registration or Piggyback Registration,  then except
     for the fees and  expenses  specified  in Section 7(a) hereof and except as
     provided below in this Section 7(b), regardless of whether any registration
     statement becomes effective,  HAGLER BAILLY shall pay all expenses incident
     to a Demand  Registration  or Piggyback  Registration,  including,  without
     limitation,  all  registration,  qualification  and filing  fees,  fees and
     expenses of compliance with Blue Sky laws,  underwriting  discounts,  fees,
     and  expenses  (other than the PHB  Stockholders'  pro rata  portion of any
     underwriting discounts or commissions or the equivalent thereof),  printing
     expenses, messenger and delivery expenses, and fees and expenses of counsel
     for HAGLER BAILLY and all  independent  certified  public  accountants  and
     other persons retained by HAGLER BAILLY.

          8. Indemnification.

          (a) HAGLER BAILLY agrees to indemnify, to the extent permitted by law,
     each  holder of  Registerable  Securities,  each Person who  controls  such
     holder  (within the meaning of Section 15 of the  Securities Act or Section
     20 of the Exchange Act) and their respective officers, directors, partners,
     employees, agents



                                     - 7 -
<PAGE>


     and representatives,  against all losses, claims, damages,  liabilities and
     expenses  ("Losses")  arising  out of or based  upon any  untrue or alleged
     untrue statement of material fact contained in any registration  statement,
     prospectus,   or  preliminary   prospectus  or  any  amendment  thereof  or
     supplement  thereto or any omission or alleged  omission of a material fact
     required to be stated therein or necessary to make the statements  therein,
     in light of the  circumstances  under which they were made, not misleading,
     except  insofar as the same are caused by or contained  in any  information
     furnished  in writing to HAGLER  BAILLY by such  holder  expressly  for use
     therein or by such holder's  failure to deliver a copy of the  registration
     statement or prospectus  or any  amendments  or  supplements  thereto after
     HAGLER BAILLY has furnished such holder with a sufficient  number of copies
     of the same and except  insofar as the same are caused by or  contained  in
     any  prospectus  if such  holder  failed  to send or  deliver a copy of any
     subsequent  prospectus or prospectus  supplement which would have corrected
     such untrue or alleged  untrue  statement of material fact or such omission
     or alleged  omission  of a material  fact with or prior to the  delivery of
     written  confirmation  of the sale by such holder after  HAGLER  BAILLY has
     furnished  such holder with a sufficient  number of copies of the same.  In
     connection with an underwritten offering, HAGLER BAILLY will indemnify such
     underwriters,  each  Person who  controls  such  underwriters  (within  the
     meaning of Section 15 of the  Securities  Act or Section 20 of the Exchange
     Act) and their respective officers, directors,  partners, employees, agents
     and  representatives  to the same extent as provided  above with respect to
     the indemnification of the holders of Registerable Securities.

          (b) In connection with any registration  statement in which holders of
     Registerable Securities are participating, each such holder will furnish to
     HAGLER BAILLY in writing such  information  and affidavits as HAGLER BAILLY
     reasonably  requests  for use in  connection  with  any  such  registration
     statement or prospectus and, to the extent permitted by law, will indemnify
     HAGLER BAILLY,  each Person who controls  HAGLER BAILLY (within the meaning
     of Section 15 of the  Securities Act or Section 20 of the Exchange Act) and
     their  respective  officers,  directors,  partners,  employees,  agents and
     representatives  against any Losses arising out of or based upon any untrue
     or  alleged   untrue   statement  of  a  material  fact  contained  in  any
     registration statement,  prospectus,  or form of prospectus, or arising out
     of or based upon any  omission  or  alleged  omission  of a  material  fact
     required to be stated therein or necessary to make the statements  therein,
     in light of the  circumstances  under which they were made, not misleading,
     to the extent,  but only to the extent,  that such untrue or alleged untrue
     statement is contained in, or such omission or alleged omission is required
     to be contained in, any  information so furnished in writing by such holder
     to  HAGLER  BAILLY  expressly  for use in such  registration  statement  or
     prospectus  and that such  statement  or omission was relied upon by HAGLER
     BAILLY in preparation of such registration statement, prospectus or form of
     prospectus;  provided, however, that such holder of Registerable Securities
     shall  not be liable in any such case to the  extent  that the  holder  has
     furnished  in  writing  to HAGLER  BAILLY  prior to the  filing of any such



                                     - 8 -
<PAGE>


     registration  statement or prospectus  or amendment or  supplement  thereto
     information expressly for use in such registration  statement or prospectus
     or any  amendment  or  supplement  thereto  which  corrected  or  made  not
     misleading  information  previously  furnished to HAGLER BAILLY, and HAGLER
     BAILLY failed to include such  information  therein.  In no event shall the
     liability of any selling  holder of  Registerable  Securities  hereunder be
     greater in amount than the dollar amount of the proceeds (net of payment of
     all  expenses)  received by such  holder upon the sale of the  Registerable
     Securities giving rise to such indemnification  obligation.  Such indemnity
     shall remain in full force and effect regardless of any investigation  made
     by or on behalf of such indemnified party.

          (c) If any Person  shall be  entitled  to  indemnity  hereunder,  such
     indemnified  party  shall give prompt  notice to the party or parties  from
     which such  indemnity is sought of the  commencement  of any action,  suit,
     proceeding or investigation or written threat thereof  ("Proceeding")  with
     respect  to  which  such  indemnified   party  seeks   indemnification   or
     contribution  pursuant hereto;  provided,  however,  that the failure to so
     notify the indemnifying  parties shall not relieve the indemnifying parties
     from any  obligation or liability  hereunder  except to the extent that the
     indemnifying parties have been prejudiced by such failure. The indemnifying
     parties shall have the right,  exercisable  by giving  written notice to an
     indemnified  party  promptly  after the receipt of written notice from such
     indemnified  party  of such  Proceeding,  to  assume,  at the  indemnifying
     parties'  expense,  the  defense  of  any  such  Proceeding,  with  counsel
     reasonably satisfactory to such indemnified party; provided,  however, that
     an indemnified party or parties (if more than one such indemnified party is
     named in any Proceeding) shall have the right to employ separate counsel in
     any such Proceeding and to participate in the defense thereof, but the fees
     and  expenses of such counsel  shall be at the expense of such  indemnified
     party or parties  unless the parties to such  Proceeding  include  both the
     indemnified  party or parties and the  indemnifying  party or parties,  and
     there exists,  in the opinion of the parties'  counsel,  a conflict between
     one or more indemnifying  parties and one or more indemnified  parties,  in
     which case the indemnifying  parties shall, in connection with any one such
     Proceeding or separate but substantially  similar or related Proceedings in
     the same  jurisdiction,  arising  out of the same  general  allegations  or
     circumstances,  be liable  for the fees and  expenses  of not more than one
     separate firm of attorneys (together with appropriate local counsel) at any
     time for  such  indemnified  party or  parties.  If an  indemnifying  party
     assumes the defense of such Proceeding,  the indemnifying  parties will not
     be subject to any  liability  for any  settlement  made by the  indemnified
     party without its or their  consent  (such  consent not to be  unreasonably
     withheld).

          (d)  If  the  indemnification  provided  for  in  this  Section  8  is
     unavailable  to an  indemnified  party  or is  insufficient  to  hold  such
     indemnified  party harmless for any Losses in respect of which this Section
     8 would  otherwise apply by its terms,  then each  applicable  indemnifying
     party, in lieu of indemnifying such indemnified  party,  shall have a joint
     and several  obligation to contribute to the



                                     - 9 -
<PAGE>


     amount  paid or  payable  by such  indemnified  party as a  result  of such
     Losses,  in such proportion as is appropriate to reflect the relative fault
     of the indemnifying  party, on the one hand, and such indemnified party, on
     the other hand,  in  connection  with the actions,  statements or omissions
     that  resulted  in such  Losses  as well as any  other  relevant  equitable
     considerations.  The relative fault of such indemnifying  party, on the one
     hand,  and  indemnified  party,  on the other hand,  shall be determined by
     reference to, among other things, whether any action in question, including
     any untrue or alleged  untrue  statement of a material  fact or omission or
     alleged omission to state a material fact, has been taken by, or relates to
     information  supplied by, such indemnifying party or indemnified party, and
     the  parties'  relative  intent,  knowledge,   access  to  information  and
     opportunity  to correct or prevent any such action,  statement or omission.
     The amount  paid or  payable by a party as a result of any Losses  shall be
     deemed to include  any legal or other  fees or  expenses  incurred  by such
     party in  connection  with any  Proceeding,  to the extent such party would
     have  been  indemnified  for  such  expenses  under  Section  8(c)  if  the
     indemnification  provided for in Section 8(a) or 8(b) was available to such
     party.  The parties hereto agree that it would not be just and equitable if
     contribution  pursuant to this  Section  8(d) were  determined  by pro rata
     allocation or by any other method of allocation  that does not take account
     of the equitable  considerations  referred to in the immediately  preceding
     paragraph.   Notwithstanding   the  provision  of  this  Section  8(d),  an
     indemnifying  party  that is a selling  holder of  Registerable  Securities
     shall not be required to  contribute  any amount in excess of the amount by
     which the net  proceeds  received by such  indemnifying  party  exceeds the
     amount of any  damages  that such  indemnifying  party has  otherwise  been
     required to pay by reasons of such untrue or alleged  untrue  statement  or
     omission   or   alleged   omission.   No  person   guilty   of   fraudulent
     misrepresentation  (within the meaning of Section  11(f) of the  Securities
     Act) shall be entitled to  contribution  from any Person who was not guilty
     of such fraudulent misrepresentation.

          9. Information by Holder. Each holder of Registerable Securities shall
     furnish to HAGLER BAILLY and to the managing  underwriter  such information
     regarding  such  holder and the  distribution  proposed  by such  holder as
     HAGLER BAILLY or the managing underwriter may reasonably request in writing
     and as shall be reasonably  required in connection  with any  registration,
     qualification or compliance referred to in Section 3.

          10. Rule 144 Reporting.  With a view to making  available the benefits
     of certain  rules and  regulations  of the SEC which may permit the sale of
     restricted  securities (as that term is defined in Rule 144(a)(3) under the
     Securities  Act) to the public without  registration,  HAGLER BAILLY agrees
     to:

               (a) use its best efforts to file with the SEC in a timely  manner

          11. Definitions. The following terms shall have the following meanings
     for purposes of this Agreement:

               "Affiliate" means, with respect to a specified Person, any Person
          controlling, controlled by or under common control with such Person.

               "Exchange  Act" means the  Securities  Exchange  Act of 1934,  as
          amended from time to time.

               "Person" means an individual,  a  partnership,  a corporation,  a
          limited liability  company,  an association,  a joint stock company, a
          trust,  a  joint  venture,   an  unincorporated   organization  and  a
          governmental entity or any department, agency or political subdivision
          thereof.

               "PHB Stockholders"  means all of the stockholders of PHB who have
          signed this  Agreement and any successor or permitted  assignee of any
          of their rights hereunder that holds Registerable Securities.

               "Registerable  Securities"  means all  shares  of  HAGLER  BAILLY
          Common Stock held at the relevant time by a PHB  Stockholder,  and any
          other issued or issuable  shares of HAGLER  BAILLY Common Stock issued
          in  connection  with  the  Merger  held  by a PHB  Stockholder  at the
          relevant time, either at the time of initial issuance or subsequently,

          purposes of this Agreement,  a PHB Stockholder  will be deemed to be a
          holder of  Registerable  Securities  whenever such PHB Stockholder has
          the  right  to  acquire  directly  or  indirectly  such   Registerable
          Securities  (upon conversion or exercise in connection with a transfer
          of securities or  otherwise,  but  disregarding  any  restrictions  or
          limitations  upon the  exercise  of such  right),  whether or not such
          acquisition has actually been effected.

               "Securities  Act" means the  Securities  Act of 1933,  as amended
          from time to time.

     Registerable Securities.

     BAILLY  to  register  any  equity  securities  of  HAGLER  BAILLY,  or  any
     securities  convertible  or  exchangeable  into  or  exercisable  for  such
     securities,  which are  materially  more favorable to such Persons than the
     rights granted to the holders of Registerable  Securities hereunder without
     the prior  written  consent of the  holders  of at least a majority  of the
     Registerable  Securities,   unless  HAGLER  BAILLY  agrees  to  amend  this
     Agreement  to  grant  such  more   favorable   rights  to  the  holders  of
     Registerable Securities, in lieu of the rights granted hereunder.

          15. Transfer of  Registration  Rights;  Successors and Assigns.  A PHB
     Stockholder may not transfer or assign its rights hereunder, in whole or in
     part,  to a purchaser or other  transferee of its  Registerable  Securities
     without the prior  approval of HAGLER  BAILLY,  except to an Affiliate of a
     PHB Stockholder.

          16. Successors and Assigns.  This Agreement shall inure to the benefit
     of and be binding upon the successors and permitted  assigns of each of the
     parties, including,  without limitation and without the need for an express
     assignment,  Affiliates  of the PHB  Stockholders.  If any PHB  Stockholder
     shall acquire Registerable Securities,  in any manner, whether by operation
     of law or otherwise,  such Registerable Securities shall be held subject to
     all of the  terms  of  this  Agreement,  and by  taking  and  holding  such
     Registerable  Securities  such  Person  shall be  entitled  to receive  the
     benefits hereof and shall be conclusively deemed to have agreed to be bound
     by all of the terms and provisions hereof.

          17. Severability.  Whenever possible, each provision of this Agreement
     shall be  interpreted  in such  manner as to be  effective  and valid under
     applicable  law,  but if any  provision  of  this  Agreement  is held to be
     prohibited by or invalid under  applicable  law,  such  provision  shall be
     ineffective only to the extent of such  prohibition or invalidity,  without
     invalidating the remainder of this Agreement.

          18.  Counterparts.  This  Agreement  may be  executed in any number of
     counterparts  and by the parties hereto in separate  counterparts,  each of
     which when so executed  shall be deemed to be an original  and all of which
     taken together shall constitute one and the same agreement.

          19.  Headings.  The  headings in this  Agreement  are for  convenience
     reference only and shall not limit or otherwise affect the meaning hereof.

     effect to the conflicts of laws provisions thereof.

          21. Specific  Performance.  The parties hereto  acknowledge that there
     would be no adequate remedy at law if any party fails to perform any of its
     obligations  hereunder,  and accordingly agree that each party, in addition
     to any other remedy to which it may be entitled at law or in equity,  shall
     be entitled to compel specific  performance of the obligations of any other
     party under this  Agreement in accordance  with the terms and conditions of

     having jurisdiction.

             Re: Affiliate Agreement

Ladies and Gentlemen:

     The  undersigned  is a  stockholder  of HAGLER  BAILLY,  INC.,  a  Delaware

wholly-owned  subsidiary  of  HAGLER  BAILLY.  Under  the  terms  of the  Merger
Agreement,  Merger Sub will be merged with and into PHB (the  "Merger")  and the
shares of common  stock of PHB,  $0.01  par  value  per share  (the "PHB  Common

HAGLER BAILLY,  par value $0.01 per share ("HAGLER BAILLY Common  Stock").  This
Affiliate's Agreement represents an agreement between the undersigned and HAGLER
BAILLY regarding certain rights and obligations of the undersigned in connection
with  the  shares  of  HAGLER  BAILLY  Common  Stock  beneficially  owned by the
undersigned.  Unless otherwise  indicated,  capitalized terms not defined herein
have the meanings set forth in the Merger Agreement.

     In consideration of the Merger and the mutual covenants  contained  herein,
the undersigned and HAGLER BAILLY hereby agree as follows:

Securities Act of 1933, as amended (the "1933 Act").

     2.  Restriction on Disposition.  The undersigned  agrees that from the date
that is 30 days prior to the Effective  Time he or she will not sell,  transfer,

relative  to, any of the  shares of HAGLER  BAILLY  Common  Stock over which the
undersigned

<PAGE>


has or shares voting or dispositive  power until such time as financial  results
covering at least 30 days of  post-Merger  combined  operations of HAGLER BAILLY
and PHB have been published,  whether by issuance of a quarterly earnings report
on Form 10-K,  10-Q or other  public  issuance  (such as a press  release)  that
includes such information.  The undersigned understands that reducing his or her
risk relative to such shares of HAGLER BAILLY Common Stock includes,  but is not

such shares.

     3.  Restrictions on Transfer.  The undersigned  understands and agrees that
HAGLER BAILLY,  at its  discretion,  may cause stop transfer  instructions  with
respect to the shares of HAGLER  BAILLY  Common  Stock to be given to the HAGLER
BAILLY transfer agent.

     4.  Understanding  of  Restrictions  on  Dispositions.  The undersigned has
carefully read this  Affiliate's  Agreement and discussed its  requirements  and
impact upon his or her ability to sell,  transfer,  or otherwise  dispose of the
shares of HAGLER BAILLY Common Stock held by the  undersigned,  to the extent he
or she believes necessary, with his or her counsel.

     5.  Acknowledgments.   The  undersigned  recognizes  and  agrees  that  the
foregoing  provisions also may apply to (i) the  undersigned's  spouse,  if that
spouse  has  the  same  home  as  the  undersigned,  (ii)  any  relative  of the
undersigned who has the same home as the undersigned,  (iii) any trust or estate
in which the undersigned, such spouse, and any such relative collectively own at
least a 10%  beneficial  interest  or of which  any of the  foregoing  serves as

                                __________, 1998


Hagler Bailly, Inc.
1530 Wilson Boulevard
Arlington, Virginia  22209

             Re:      Affiliate Agreement

Ladies and Gentlemen:

     The  undersigned  is a  stockholder  of PUTNAM,  HAYES & BARTLETT,  INC., a
Massachusetts  corporation  ("PHB"),  and may  become a  stockholder  of  HAGLER
BAILLY,  INC.,  a  Delaware  corporation  ("HAGLER  BAILLY"),  pursuant  to  the
transactions  described in the  Agreement  and Plan of Merger,  dated as of June
___, 1998 (the "Merger  Agreement"),  by and among PHB,  HAGLER BAILLY,  and PHB
MERGER  CORP.,  a  Delaware   corporation  ("Merger  Sub")  and  a  wholly-owned
subsidiary of HAGLER BAILLY. Under the terms of the Merger Agreement, Merger Sub
will be merged with and into PHB (the  "Merger")  and the shares of common stock
of PHB,  $0.01 par value per share (the "PHB Common  Stock")  will be  converted
into and  exchanged for the shares of common stock of HAGLER  BAILLY,  par value
$0.01 per share  ("HAGLER  BAILLY Common  Stock").  This  Affiliate's  Agreement
represents an agreement  between the  undersigned  and HAGLER  BAILLY  regarding
certain  rights and  obligations of the  undersigned in connection  with the (i)
shares of PHB Common Stock beneficially owned by the undersigned and (ii) shares
of HAGLER  BAILLY  Common  Stock into which such shares of PHB Common  Stock are
converted as a result of the Merger.  Unless  otherwise  indicated,  capitalized
terms not defined herein have the meanings set forth in the Merger Agreement.

     In consideration of the Merger and the mutual covenants  contained  herein,
the undersigned and HAGLER BAILLY hereby agree as follows:

     1. Affiliate status. The undersigned  understands and agrees that as to PHB
he or she  may be  deemed  to be an  "affiliate"  as  that  term  is used in SEC
Accounting  Series  Release  Nos.  130 and 135 and  Rule  145 of the  rules  and
regulations  of  the  Securities  and  Exchange  Commission  ("SEC")  under  the
Securities Act of 1933, as amended (the "1933 Act").

     2.  Restriction on Disposition.  The undersigned  agrees that from the date
that is 30 days prior to the Effective  Time he or she will not sell,  

<PAGE>


transfer,  or otherwise dispose of his or her interests in, or reduce his or her
risk  relative  to,  any of the (a)  shares of PHB  Common  Stock over which the
undersigned has or shares voting or dispositive power or, if applicable, (b) any
of the shares of HAGLER BAILLY Common Stock into which such shares of PHB Common
Stock are converted upon  consummation of the Merger or upon the exercise of any
HAGLER BAILLY options, until such time as financial results covering at least 30
days of  post-Merger  combined  operations  of HAGLER  BAILLY  and PHB have been
published, whether by issuance of a quarterly earnings report on Form 10-K, 10-Q
or  other  public  issuance  (such  as  a  press  release)  that  includes  such
information.  The undersigned understands that reducing his or her risk relative
to such shares of PHB Common Stock or HAGLER BAILLY Common Stock  includes,  but
is not limited to, using such shares to secure a non-recourse loan, purchasing a
put  option to sell such  shares or  otherwise  entering  a put  agreement  with
respect to such shares.

     3. Covenants and Warranties of  Undersigned.  The  undersigned  represents,
warrants and agrees that:

     (a) HAGLER BAILLY has advised the undersigned that the HAGLER BAILLY Common
Stock  has not been  registered  under  the 1933 Act and that  shares  of HAGLER
BAILLY  Common  Stock  received  pursuant  to the Merger can only by sold by the
undersigned (1) following  registration under the 1933 Act, or (2) pursuant to a
valid exemption from registration  under the 1933 Act and upon receipt by HAGLER
BAILLY of an opinion of counsel  satisfactory to HAGLER BAILLY that such sale is
in compliance with the 1933 Act and state securities laws.

     (b) The undersigned is aware that HAGLER BAILLY, PHB, and Merger Sub intend
to treat the  merger  as a  tax-free  reorganization  under  Section  368 of the
Internal  Revenue  Code (the  "Code")  for  federal  income  tax  purposes.  The
undersigned agrees to treat the transaction in the same manner as HAGLER BAILLY,
PHB,  and  Merger  Sub  for  federal  income  tax  purposes.   The   undersigned
acknowledges  that Section  1.368-1(b)  of the Income Tax  Regulations  requires
"continuity  of  interest"  in order for the  Merger to be treated as a tax-free
reorganization  under Section 368 of the Code. This requirement is satisfied if,
taking into account  those of the PHB  stockholders  who receive cash in lieu of
fractional shares, or who dissent from the Merger, there is no plan or intention
on the part of PHB  stockholders  to sell or  otherwise  dispose  of the  HAGLER
BAILLY  Common  Stock that may be  received  in the Merger that will reduce such
stockholders'  ownership to a number of shares having, in the aggregate, a value
at the time of the Merger of less than 50% of the total fair market value of PHB
Common Stock outstanding  immediately  prior to the Merger.  The undersigned (i)
has no present  plan or  intention  to sell or  otherwise  dispose of his or her
HAGLER BAILLY  Common Stock to be received in the Merger,  and (ii) is not aware
of, or participating in, any plan or intent on the part of holders of PHB Common
Stock to engage in sales or other  dispositions  of HAGLER  BAILLY  Common Stock
received

                                      -2-

<PAGE>


in the Merger,  such that the aggregate  fair market value,  as of the effective
time of the Merger,  of the shares of HAGLER BAILLY Common Stock subject to such
sales or other  dispositions  would exceed fifty  percent (50%) of the aggregate
fair market value of all outstanding PHB Common Stock  immediately  prior to the
Merger.   The   undersigned   acknowledges   that  he  or  she  is  giving  this
representation and covenant to enable Ernst & Young L.L.P. to provide reasonable
assurances  that the Merger  constitutes  a tax-free  reorganization  within the
meaning of Section 368 of the Tax Code and further  recognizes that  significant
adverse tax consequences might result if this representation is not true.

          4.   Restrictions on Transfer.

     (a) The undersigned  understands and agrees that stop transfer instructions
with  respect  to the  shares of HAGLER  BAILLY  Common  Stock  received  by the
undersigned  pursuant to the Merger will be given to the HAGLER BAILLY  transfer
agent.

     (b)  The  undersigned   understands  that  there  will  be  placed  on  the
certificates  for such  shares,  or shares  issued in  substitution  thereof,  a
"pooling of interests" legend stating substantially as follows:

               "The shares  represented by this certificate were issued pursuant
               to a business combination which is accounted for as a "pooling of
               interests"  and may not be sold, nor may the owner thereof reduce
               his risks relative  thereto in any way, until such time as HAGLER
               BAILLY,  Inc.  ("HAGLER  BAILLY")  has  published  the  financial
               results  covering at least 30 days of combined  operations  after
               the  effective  date of the  merger  through  which the  business
               combination was effected."

Upon the request of the undersigned,  HAGLER BAILLY shall cause the certificates
representing  the shares of HAGLER BAILLY Common Stock issued to the undersigned
in  connection  with the Merger to be  reissued  free of any legend  relating to
restrictions  on  transfer  by virtue of ASR 130 and 135 as soon as  practicable
after the requirements of ASR 130 and 135 have been met.

     (c) In addition,  the undersigned  understands that there will be placed on
the certificates for such shares,  or shares issued in substitution  thereof,  a
securities law legend stating substantially as follows:

               "THE  SECURITIES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT BEEN
               REGISTERED  UNDER THE  SECURITIES  ACT OF 1933,  AS AMENDED  (THE
               "ACT") OR UNDER THE SECURITIES LAW OF ANY STATE.  SUCH SECURITIES
               MAY NOT

                                      -3-

<PAGE>


               BE  SOLD  OR  OFFERED  FOR  SALE  OR  OTHERWISE  HYPOTHECATED  OR
               DISTRIBUTED  EXCEPT (A)  PURSUANT  TO AN  EFFECTIVE  REGISTRATION
               STATEMENT FOR SUCH  SECURITIES  UNDER THE ACT; OR (B)(i) PURSUANT
               TO A VALID  EXEMPTION  FROM SUCH  REGISTRATION  UNDER THE ACT AND
               UNDER  APPLICABLE STATE SECURITIES LAWS, AND (ii) UPON RECEIPT BY
               HAGLER  BAILLY OF AN  OPINION OF COUNSEL  FOR THE  HOLDER,  WHICH
               OPINION  SHALL BE  SATISFACTORY  IN FORM AND  SUBSTANCE TO HAGLER
               BAILLY,  THAT  SUCH SALE IS IN  COMPLIANCE  WITH THE ACT AND SUCH
               STATE SECURITIES LAW."

Such legend will also be placed on any  certificate  representing  HAGLER BAILLY
securities  issued  subsequent  to the  original  issuance of the HAGLER  BAILLY
Common  Stock  pursuant to the Merger as a result of any stock  dividend,  stock
split,  or other  recapitalization  as long as the HAGLER  BAILLY  Common  Stock
issued to the  undersigned  pursuant to the Merger has not been  transferred  in
such manner to justify the removal of the legend therefrom.  In addition, if the
provisions of Rules 144 and 145 are amended to eliminate restrictions applicable
to the HAGLER BAILLY Common Stock  received by the  undersigned  pursuant to the
Merger, or at the expiration of the restrictive period set forth in Rule 145(d),
HAGLER BAILLY, upon the request of the undersigned,  will cause the certificates
representing  the shares of HAGLER BAILLY Common Stock issued to the undersigned
in connection  with the Merger to be reissued free of any legend relating to the
restrictions  set forth in Rules 144 and 145(d) upon receipt by HAGLER BAILLY of
an opinion of its counsel to the effect that such legend may be removed.

     5.  Understanding  of  Restrictions  on  Dispositions.  The undersigned has
carefully read the Merger Agreement and this Affiliate's Agreement and discussed
their  requirements  and impact  upon his or her ability to sell,  transfer,  or
otherwise  dispose of the shares of HAGLER BAILLY  Common Stock  received by the
undersigned,  to  the  extent  he or she  believes  necessary,  with  his or her
counsel.

     6.  Transfer  Under  Rule  145(d).  If the  undersigned  desires to sell or
otherwise transfer the shares of HAGLER BAILLY Common Stock that may be received
by him or her in connection  with the Merger at any time during the  restrictive
period set forth in Rule 145(d),  the  undersigned  will  provide the  necessary
representation  letter to the  transfer  agent for HAGLER  BAILLY  Common  Stock
together with such  additional  information as the transfer agent may reasonably
request.  If counsel  to HAGLER  BAILLY  concludes  that such  proposed  sale or
transfer  complies  with the  requirements  of Rule 145(d),  HAGLER BAILLY shall
cause such  counsel to provide  such  opinions as may be necessary to the 

                                      -4-

<PAGE>


HAGLER BAILLY  transfer agent so that the  undersigned may complete the proposed

as necessary in order to permit the undersigned to sell his or her HAGLER BAILLY
Common Stock pursuant to Rule 145 and, to the extent applicable,  Rule 144 under
the 1933 Act,  HAGLER BAILLY will use its  reasonable  best efforts to file on a

undersigned  to sell,  pursuant to the terms and  conditions of Rule 145 and the
applicable provisions of Rule 144, his or her HAGLER BAILLY Common Stock.

     8.  Acknowledgments.   The  undersigned  recognizes  and  agrees  that  the
foregoing  provisions also may apply to (i) the  undersigned's  spouse,  if that
spouse  has  the  same  home  as  the  undersigned,  (ii)  any  relative  of the
undersigned who has the same home as the undersigned,  (iii) any trust or estate

trustee, executor, or in any similar capacity, and (iv) any corporation or other
organization  in which  the  undersigned,  such  spouse,  and any such  relative

                          Donaldson, Lufkin & Jenrette
              Donaldson, Lufkin & Jenrette Securities Corporation
           277 Park Avenue, New York, New York 10172 o (212) 892-3000







                                  June 8, 1998



Board of Directors
Hagler Bailly, Inc.
1530 Wilson Boulevard
Suite 400
Arlington, VA 22209-2409

Dear Sirs:

     You have requested our opinion as to the fairness from a financial point of
view to the stockholders of Hagler Bailly,  Inc. (the "Company") of the Exchange
Ratio (as  defined  below)  pursuant to the terms of the  Agreement  and Plan of
Merger,  to be dated as of June 9,  1998  (the  "Agreement"),  by and  among the
Company,  PHB Merger Corp.  ("Merger  Sub"),  a  wholly-owned  subsidiary of the
Company, and Putnam, Hayes & Bartlett, Inc. ("PHB") pursuant to which Merger Sub
will be merged (the "Merger") with and into PHB.

     Pursuant to the Agreement,  each share of common stock, par value $0.01 per
share, of PHB ("PHB Common Stock") will be converted into and exchangeable  for,
subject to certain  exceptions,  a number of shares of common  stock,  par value
$0.01 per share,  of the Company  ("Company  Common  Stock")  equal to 6,600,000
divided  by the  number of shares of PHB Common  Stock  issued  and  outstanding
immediately prior to consummation of the Merger (the "Exchange Ratio").

          In arriving at our opinion,  we have  reviewed the draft dated June 5,
1998 of the  Agreement.  We have also reviewed  financial and other  information
that was publicly  available or furnished to us by the Company and PHB including
information  provided  during  discussions  with their  respective  managements.
Included in the  information  provided  during  discussions  with the respective
managements were (1) preliminary  unaudited financial  statements of PHB for the
year ended  December 31, 1997 and the quarter  ended March 31, 1998  prepared by
the management of PHB, (2) certain  financial  projections of PHB for the period
beginning  January  1,  1998  and  ending  December  31,  2002  prepared  by the
management of PHB and (3) certain  financial  projections of the Company for the
period  beginning  January 1, 1998 and ending  December 31, 2002 prepared by the
management of the Company.  In addition,  we have compared certain financial and
securities  data of the  Company  and PHB with  various  other  companies  whose
securities are traded in public  markets,  reviewed the historical  stock prices
and trading  volumes of Company Common Stock and conducted such other  financial
studies,  analyses and  investigations as we deemed  appropriate for purposes of
this opinion.

          In rendering our opinion, we have relied upon and assumed the accuracy
and  completeness  of  all of the  financial  and  other  information  that  was
available to us from public sources, that was provided to



<PAGE>




us by the  Company  and PHB or  their  respective  representatives,  or that was
otherwise reviewed by us. With respect to the financial  information supplied to
us, we have  assumed that (1) the  financial  projections  have been  reasonably
prepared on the basis  reflecting  the best  currently  available  estimates and
judgments of the  managements of the Company and PHB as to the future  operating
and  financial  performance  of the  Company  and PHB and (2) the final  audited
financial  statements of PHB for the year ended December 31, 1997 and the final
unaudited financial  statements of PHB for the quarter ended March 31, 1998 will
not differ materially from the preliminary unaudited statements furnished to us,
with the  exception  of any  changes  as the  result of the  stock  compensation
charge.  We have not  assumed  any  responsibility  for making  any  independent
evaluation  of  any  assets  or  liabilities  or  for  making  any   independent
verification  of any of the  information  reviewed  by us. We have  relied as to
certain legal matters on advice of counsel to the Company.  Our opinion  assumes
that the  Merger  qualifies  as a  tax-free  reorganization  and for  pooling of
interests accounting treatment.

          Our opinion is necessarily  based on economic,  market,  financial and
other  conditions as they exist on, and on the information  made available to us
as of,  the  date of  this  letter.  It  should  be  understood  that,  although
subsequent  developments may affect this opinion,  we do not have any obligation
to update,  revise or reaffirm this opinion. We are expressing no opinion herein
as to the prices at which the Company  Common Stock will  actually  trade at any
time.  Our opinion  does not address the  relative  merits of the Merger and the
other business  strategies being considered by the Company's Board of Directors,
nor does it address the Board's decision to proceed with the Merger. Our opinion
does not constitute a recommendation to any holder of Company Common Stock as to
how such holder should vote on the proposed transaction.

          Donaldson,  Lutkin & Jenrette Securities  Corporation ("DLJ"), as part
of its investment  banking  services,  is regularly  engaged in the valuation of
businesses   and   securities   in  connection   with   mergers,   acquisitions,
underwritings,  sales and  distributions  of  listed  and  unlisted  securities,
private  placements and valuations  for corporate and other  purposes.  DLJ lead
managed the Company's  $50.7 million  initial  public  offering in July 1997 and
received  usual and  customary  underwriter's  compensation  for such  services.
Pursuant to the terms of the engagement  letter between the Company and DLJ, DLJ
shall  have the right to act as lead  managing  underwriter  to the  Company  in
connection  with any public  equity  financing by the Company  which is effected
within 12 months following consummation of the Merger.

          Based upon the foregoing  and such other factors as we deem  relevant,
we are of the opinion that the Exchange  Ratio is fair to the holders of Company
Common Stock from a financial point of view.

                                            Very truly yours, 
                                           
                                            DONALDSON, LUFKIN & JENRETTE

     We have  audited the  accompanying  consolidated  balance  sheets of Hagler
Bailly,  Inc. (the "Company") and subsidiaries as of December 31, 1996 and 1997,
and the related consolidated statements of operations, stockholders' equity, and
cash flows for each of the three years in the period  ended  December  31, 1997.
These financial statements are the responsibility of Hagler Bailly's management.
Our responsibility is to express an opinion on these financial  statements based
on our audits.  We did not audit the financial  statements  of Apogee  Research,
Inc., a wholly owned  subsidiary,  as of December 31, 1996,  and for each of the
two years ended December 31, 1996, which statements reflect total assets of $3.0
million at  December  31,  1996,  and total  revenues  of $6.6  million and $6.4
million for the two years then ended.  Those  statements  were  audited by other
auditors whose report has been  furnished to us, and our opinion,  insofar as it
relates to data  included  for Apogee  Research,  Inc.,  is based  solely on the
report of the other auditors.

     We conducted  our audits in accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion,  based on our audits and the report of other auditors,  the
consolidated  financial  statements  referred to above  present  fairly,  in all
material respects,  the consolidated  financial position of Hagler Bailly,  Inc.
and its  subsidiaries as of December 31, 1996 and 1997, and the results of their
operations  and their cash flows for each of the three years in the period ended
December 31, 1997, in conformity with generally accepted accounting principles.

                   Notes to Consolidated Financial Statements
                           December 31, 1996 and 1997

1.   Organization

Hagler Bailly,  Inc. ("Hagler Bailly" or the "Company") is a worldwide  provider
of management  consulting and other advisory  services to the private and public
sectors.  The Company operates in principally one business segment.  The firm is
headquartered in the Washington,  D.C.  metropolitan area and has offices in the
United States, Asia, Europe, and Latin America.

Hagler Bailly was  organized  under the laws of the state of Delaware and formed
for the primary  purpose of facilitating  the acquisition of RCG/Hagler  Bailly,
Inc.  ("Predecessor")  by its  management.  The  Predecessor  was a wholly-owned
subsidiary  of RCG  International,  Inc.  ("RCG").  The date of inception of the
Company was May 5, 1995.  The Company had no operations  from May 5, 1995 to May
25,  1995.  Effective  on the close of business on May 25,  1995,  the  Company,
through a  wholly-owned  subsidiary,  acquired  all of the  voting  stock of the
Predecessor and the Company began operations on May 26, 1995.

On July 3, 1997 the Company  consummated an initial public offering of 2,500,000
shares at an offering  price of $14 per share.  The offering  netted the Company
$30.3  million  to  be  used  to  pay  off  all  debt  then  outstanding,   fund
acquisitions, and provide ongoing working capital needs.

On December 1, 1997, the Company acquired all of the outstanding common stock of
Apogee Research, Inc. ("Apogee") (see Note 17). On February 23, 1998 the Company
completed the acquisition of TB&A Group,  Inc. and its wholly-owned  subsidiary,
Theodore Barry & Associates  ("TB&A") (see Note 17). Both business  combinations
were  accounted for as a  pooling-of-interests.  Accordingly,  the  consolidated
financial  statements  include the  accounts of the Company,  its  subsidiaries,
Apogee and TB&A for all periods presented.

2.   Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated  financial  statements  include the accounts of the Company and
its  wholly-owned  subsidiaries.   All  significant  intercompany  accounts  and
transactions have been eliminated in consolidation.

Use of Estimates

The  preparation  of  consolidated   financial  statements  in  conformity  with
generally accepted  accounting  principles requires management to make estimates
and assumptions that affect the amounts  reported in the consolidated  financial
statements and  accompanying  notes,  in  particular,  estimates of revenues and
contract cost used in the earnings  recognition  process.  Actual  results could
differ from those estimates.

Cash and Cash Equivalents

Cash  equivalents  are  short-term,  highly  liquid  investments,  which have an
original maturity when acquired of three months or less.

             Notes to Consolidated Financial Statements (Continued)
                           December 31, 1996 and 1997

Marketable Securities

Marketable securities are classified as  available-for-sale  and are recorded at
fair market value with unrealized gains and losses, net of taxes,  reported as a
separate component of shareholders' equity, if material.

Realized  gains and losses and  declines in market value judged to be other than
temporary are included in investment income. Interest and dividends are included
in investment income (see Note 3).

Property and Equipment

Property and  equipment  are  recorded at original  cost and  depreciated  using
primarily the straight line method over their estimated useful lives of three to
seven years.  Leasehold improvements are recorded at cost and amortized over the
shorter of their  useful  lives or the term of the related  leases by use of the
straight-line method.

Revenue Recognition

Consulting  revenue  represents  revenue generated by professional  staff of the
Company.   Subcontractor  and  other  revenue  represents  revenue   principally
generated through the use of subcontractors and independent consultants.

Revenue from cost-plus  fixed-fee  contracts is recognized as costs are incurred
on the  basis of  direct  costs  plus  allowable  indirect  costs and a pro rata
portion of estimated fee.

Revenue    from    fixed-bid    type    contracts   is    recognized    on   the
percentage-of-completion  method of accounting with costs and estimated  profits
included in revenue based on the relationship  that contract costs incurred bear
to management's  estimate of total contract costs.  Losses,  if any, are accrued
when they become known and the amount of the loss is reasonably determinable.

Revenue from standard daily rate contracts is recognized at amounts  represented
by the agreed-upon billing amounts and costs are recognized as incurred.

Amounts  billed or received in excess of revenue  recognized in accordance  with
the Company's revenue recognition policy are classified as billings in excess of
cost in the accompanying balance sheets.

Income Taxes

The Company  provides for income taxes in accordance with the liability  method.
Under this method,  deferred tax assets and liabilities are determined  based on
temporary  differences between financial and tax bases of assets and liabilities
and are  measured  using the  enacted  tax rates and laws that will be in effect
when the differences are expected to reverse.

Earnings Per Share

In 1997,  the Financial  Accounting  Standards  Board issued  Statement No. 128,
"Earnings  per Share".  Statement  128 replaced the  calculation  of primary and
fully  diluted  earnings  per share with basic and diluted  earnings  per share.
Unlike  primary  earnings  per share,  basic  earnings  per share  excludes  any
dilutive  effects of  options,  warrants  and  convertible  securities.  Diluted
earnings per share is computed very similarly to the  previously  reported fully
diluted  earnings per share. All

Recent Pronouncements

In June 1997,  the FASB  issued  Statement  No.  130,  "Reporting  Comprehensive
Income" which  established  standards for reporting and display of comprehensive
income and its components (revenues,  expenses,  gains and losses) in a full set
of  general-purpose  financial  statements.  This  statement  requires  that  an
enterprise  classify  items of other  comprehensive  income by their nature in a
financial  statement and display the accumulated  balance of other comprehensive
income separately from retained earnings and additional  paid-in-capital  in the
equity  section of the balance  sheet.  This  statement is effective  for fiscal
years beginning after December 15, 1997.

The  Company  believes  that  the  adoption  of this  statement  will not have a
material impact on its financial position or results of operations.

In June 1997, the FASB issued Statement No. 131,  "Disclosure  about Segments of
an Enterprise and Related  Information"  which established  standards for public
business  enterprises to report  information about operating  segments in annual
financial   statements  and  requires  those   enterprises  to  report  selected
information  about  operating  segments in interim  financial  reports issued to
shareholders.  It also establishes the standards for related  disclosures  about
products and services,  geographic  areas and major  customers.  This  Statement
requires that a public  business  enterprise  report  financial and  descriptive
information about its reportable operating segments.  The financial  information
is  required  to be  reported  on the  basis  that  it is  used  internally  for
evaluating  segment  performance  and  deciding  how to  allocate  resources  to
segments.  Operating  segments  are  components  of an  enterprise  about  which
separate financial  information is available that is evaluated  regularly by the
chief  operating  decision  maker in deciding how to allocate  resources  and in
assessing performance.  This statement is effective for financial statements for
periods  beginning  after  December  15,  1997.  The Company  believes  that the
adoption  of this  statement  will not have a material  impact on its  financial
position or results of operations.

In October  1997,  the AICPA issued SOP 97-2,  "Software  Revenue  Recognition,"
which  changes  the   requirements   for  revenue   recognition   effective  for
transactions  that the Company will enter into

4.   Accounts Receivable

At December 31, 1996 and 1997, the components of accounts receivable are:

                                                     1996              1997

                                                 ============      ============

The activity in the allowance for possible losses for years ended December 31 is
as follows:

                                                      1996              1997
                                                   -----------      -----------

                                                   ===========      ===========

All billed and unbilled  receivable  amounts are expected to be collected during
the next fiscal year.  Management has provided an allowance for amounts which it
believes are doubtful as to their ultimate  realization.  Substantially  all the
retention  relates to  contracts  for which a final  invoice is  submitted  upon
completion  of indirect  cost audits and  contract  close-outs;  therefore it is
anticipated that the retention amounts will not all be collected within the next
fiscal year.

5.   Property and Equipment

Components  of  property  and  equipment  at  December  31, 1996 and 1997 are as
follows:

                                                      1996             1997

   Office equipment and furniture .........        $ 4,307,426      $ 5,560,520
   Leasehold improvements .................            373,025          353,868
                                                   -----------      -----------
                                                     4,680,451        5,914,388
   Accumulated depreciated and amortization         (1,840,483)      (3,061,709)
                                                   -----------      -----------
                                                   $ 2,839,968      $ 2,852,679
                                                   ===========      ===========

Depreciation  expense for the years ended  December 31, 1995,  1996 and 1997 was
$537,854,   $918,893  and  $1,221,226,   respectively.   Costs  of  repairs  and
maintenance of property and equipment are charged to expense as incurred.

6.   Software Development Costs

At December  31,  1997,  the  Company had  recorded  $2,463,174  of  capitalized
software  development  costs net of $49,000  of  accumulated  amortization.  The
Company  accounts  for  these  development  costs in  accordance  with  FASB 86,
"Accounting for the Costs of Computer Software to Be Sold,  Leased, or Otherwise
Marketed".

Capitalized  development  costs are  amortized  on a product  by  product  basis
starting  when the  product is  available  for  general  release  to  customers.
Amortization  is calculated  using the  straight-line  method over the remaining
estimated economic life of the product. The Company  periodically  evaluates the
net realizable value of all unamortized  capitalized costs. At December 31, 1997
the Company  believes  there has been no impairment of net  realizable  value of
these recorded amounts.

7.   Management Buy-Out

Effective at the close of business on May 25, 1995, the Company purchased all of
the  outstanding  shares of RCG/Hagler  Bailly,  Inc. from RCG in an acquisition
accounted for as a purchase.  The consolidated  financial statements include the
results  of  operations  from the date of  acquisition.  Under  the terms of the
Management  Buy-Out,  the Company agreed to pay  approximately  $15,587,000  and
assume  certain tax  obligations  of the seller.  Acquisition  related  costs of
approximately  $491,000  were  incurred.  The  purchase  was  funded by  capital
contributions, bank debt, and subordinated debt from RCG.

The  purchase  price was  allocated to the assets  acquired and the  liabilities
assumed based upon their fair values as of the  acquisition  date. The excess of
the  purchase  price over the fair value of assets  acquired in the purchase was
recorded as intangible assets,  including goodwill, and are being amortized over
5 to 20 years on a straight-line  basis.  Intangible assets at December 31, 1996
and 1997 are net of  accumulated  amortization  of  $1,017,000  and  $1,753,000,
respectively.  Amortization  expense for the years ended December 31, 1995, 1996
and 1997 was $334,000, $683,000 and $736,000, respectively.

The  Company  periodically  reviews  the value of its net  intangible  assets to
determine if an impairment has occurred.  Based on its review,  the Company does
not believe that an impairment of net intangible assets has occurred at December
31, 1997.

             Notes to Consolidated Financial Statements (Continued)
                           December 31, 1996 and 1997

Pro forma unaudited  consolidated  operating results of the Company for the year
ended December 31, 1995 assuming the  acquisition had been made as of January 1,
1995 are summarized below:

   Pro forma revenue ....................................         $   64,597,974
   Pro forma net income .................................              1,594,371
   Pro forma income per share:
        Basic ...........................................                  0.47
        Diluted .........................................                  0.40

These pro forma  results have been  prepared for  comparative  purposes only and
include  adjustments  such as  additional  amortization  expenses as a result of
goodwill and other intangible  assets and increased  interest expense related to
debt  used  to  finance  the  Management  Buy-Out.  They  do not  purport  to be
indicative of the results of operations  which  actually would have resulted had
the  combination  occurred  on  January 1,  1995,  or of the  future  results of
operations of the consolidated entities.

8.   Note Receivable

During 1997 the Company entered into a bridge loan agreement for $1,000,000 with
another  company.  The loan is due in six equal  installments  beginning June 1,
1998.  The loan pays  interest at 15% and is secured by all of the assets of the
borrower.  The loan  agreement  allows the  Company  to  purchase  an  ownership
interest of this company as defined in the loan agreement.

9.   Bank Line of Credit

At December 31, 1996 and 1997, the Company had a line of credit arrangement with
a bank which  provides  funds up to $5,750,000  and  $15,000,000,  respectively,
subject to sufficient collateral. The line is secured primarily by the Company's
accounts receivable and contract rights.  Under the terms of the line of credit,
interest is payable  monthly at the bank's  prime  rate.  There is an annual fee
equal to 1/4 of 1% of the unused  portion of the available  line of credit.  The
line of credit  agreement  contains  certain  covenants which among other things
restrict future borrowings and require the Company to maintain certain financial
ratios.  At  December  31, 1996 and 1997 the  Company  had  available  borrowing
capacity of $3,150,000 and $15,000,000, respectively, under the line of credit.

10.  Notes Payable

Notes payable to financial institution

The Company has notes  payable to a financial  institution  of $1.1  million and
$180,000 at December 31, 1996 and 1997,  respectively.  At December 31, 1996 the
$1.1 million note consists of $650,000  principal  plus accrued  interest at the
prime rate plus 2% with a floor of 10% and a cap of 15%. During 1996 the Company
was engaged in  negotiations  to refinance the note under more favorable  terms.
During 1997 a refinance  agreement was reached which  consisted of cash payments
of $360,000 in 1997 to settle the  original  note and the issuance of a new note
in the amount of  $180,000.  The new note is due in twelve equal  interest  free
monthly  installments of $15,000.  The settlement  resulted in an  extraordinary
gain to the Company in 1997.  The Company  used  working  capital to finance the
settlement.

Notes payable to related-parties

The  Company  has notes  payable to  related-parties,  primarily  employees  and
directors,   of  $2,456,788   and  $620,417  at  December  31,  1996  and  1997,
respectively.  These notes are unsecured,  due on

demand and accrue  interest  at rates  which  approximate  10%.  The Company has
actively pursued the settlement of many of these notes at favorable terms.  Such
settlements  have resulted in extraordinary  gains for the Company.  The Company
used working capital to finance all settlements.

11.  Long-term Debt

     Long-term debt consisted of the following at December 31, 1996:

     Senior term loan from a bank, in the original amount of
        $7,000,000, interest payable at the bank's prime rate
        plus 7/8%.  Subject to certain limitations, the
        Company may fix the interest rate on portions or all
        of the note at LIBOR  plus 2% for periods ranging from
        30-360 days.  The interest rate was 7.6% at
        December 31, 1996.  Principal is due in quarterly
        installments ranging from $250,000 to $384,500, plus
        interest over the term of the note secured by the
        assets of the Company ......................................  $3,913,000
     Subordinated note payable to RCG in the amount of
        $4,650,000; interest at 9.5% payable semiannually;
        balloon payment due May 2001 ...............................   4,650,000
     Other notes and equipment loans; interest at rates
        approximating prime; maturities through June 30, 1999 ......     104,000
                                                                      ----------
     Total long-term debt ..........................................   8,667,000
     Less:  current portion ........................................   1,337,000
                                                                      ----------
     Long-term debt, net of current portion ........................  $7,330,000
                                                                      ==========

Cash paid for interest for the years ended December 31, 1995,  1996 and 1997 was
approximately $606,144, $1,178,513 and $926,185, respectively.

The Company used a portion of the proceeds from its initial  public  offering to
pay off all outstanding long-term debt in July 1997.

12.  Income Taxes

The Company has historically filed its consolidated federal income tax return on
the cash basis,  whereby for tax purposes,  revenue was recognized when received
and expenses  were  recognized  when paid.  The timing of certain  transactions,
primarily the  collections  of accounts  receivable and the payments of accounts
payable and accrued  expenses  were applied to different  periods for  financial
statement and income tax reporting  purposes.  Deferred federal and state income
taxes were provided for these temporary  differences.  Upon  consummation of the
IPO of the  Company's  Common  Stock  during  1997,  the Company was required to
change to the accrual method for income tax reporting.

             Notes to Consolidated Financial Statements (Continued)
                           December 31, 1996 and 1997

As a result of  historical  losses,  TB&A,  which  merged with Hagler  Bailly on
February 23, 1998, had net operating loss carryforwards at December 31, 1995 and
1996. The deferred tax assets generated by these loss  carryforwards  were fully
reserved for by the Company in the years that they were  generated.  The Company
utilized all of its carryforwards during 1997.

13.  Stockholders' Equity

The Company was  authorized at inception to issue  6,915,067  shares of $.01 par
value Class A common stock and 2,074,521 shares of $.01 par value Class B common
stock. Pursuant to a stockholders'  agreement, all of the Company's common stock
and  options  had  certain  restrictions  on  ownership  and were  subject  to a
repurchase provision.  Class B shares were not eligible for dividends and had no
voting privileges.

The Company may grant qualified and non-qualified  stock options to employees to
purchase  common  stock under the Employee  Incentive  and  Non-Qualified  Stock
Option and Restricted Stock Plan (the "Stock Plan"). Prior to December 31, 1996,
the Company's  Stock Plan was a formula  based plan and was  authorized to grant
options to purchase Class A and B shares.  The exercise price of options granted
were based upon the book value per share at May 26, 1995, adjusted for accretion
of formula value during any interim period up to the grant date. Under the Stock
Plan,  options to purchase  Class B shares  granted did not accrue  value to the
option holder until date of exercise. Options to purchase Class A shares accrued
value to the option holder from the date of grant.

Effective  at December 31,  1996,  the Company:  (i) adopted an amendment to its
Stock Plan which  changed  the  exercise  price of future  options to be granted
thereunder  to the  fair  value  of the  underlying  Common  Stock;  and (ii) in
connection with a  reclassification  of its Common Stock amended all outstanding
options  to  purchase  971,963  Class B shares  vesting  on  January  1, 1997 to
substitute  0.9 of a Class A  share  for  each  Class  B share  underlying  such
options.  In addition,  a remaining total of 971,963 options to purchase Class B
shares  vesting on  January  1, 1998 were  canceled.  As a result,  the  Company
recorded a  non-recurring,  non-cash charge to operations of $6,172,000 of which
$4,618,000  was for  options to purchase  Common  Stock and  $1,554,000  was for
394,160  shares of Common Stock sold to employees  during  1996.  These  charges
represent  the  aggregate   difference   between  the  exercise  price  of  such
outstanding  options or the  issuance  price of Common  Stock sold to  employees
during  1996,  as the  case  may  be,  and the  appraised  market  value  of the
underlying Common Stock at December 31, 1996.

Options  granted after 1996 vest over periods  ranging from  immediately to four
years and are generally  exercisable  up to ten years.  Options  issued prior to
1996  generally  vest 50% after  eighteen  months and fully after an  additional
year.  Once  vested,  the options are  exercisable  for up to ten years from the
grant date.

Pro forma  information  regarding  net  income  (loss)  and per share  data,  is
required  by SFAS  No.  123,  and has  been  determined  as if the  Company  had
accounted for its stock options  under the fair value method  therein.  The fair
value for options granted from May 25, 1997 to July 9, 1997 was estimated at the
date  of  grant   using  a  minimal   valuation   method   with  the   following
weighted-average  assumptions,  risk free  interest  rate of 5.25%,  no expected
dividends and an average expected life of the options of 5 years.

For all options issued  subsequent to July 9, 1997, in accordance with SFAS 123,
the  fair  value  of  options  was  estimated  at the  date  of  grant  using  a
Black-Scholes   option   pricing  model  with  the  following   weighted-average
assumptions  for  1997:  Risk-free  interest  rate of  5.25%;  no  dividends;  a
volatility  factor of the expected market price of the Company's common stock of
 .40 and a  weighted-average  expected  life of the  options of  approximately  5
years.

                           December 31, 1996 and 1997

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded  options which have no vesting  restrictions  and are fully
transferable.  In addition,  option valuation models require the input of highly
subjective  assumptions  including the expected stock price volatility.  Because
the  Company's  employee  stock  options  have   characteristics   significantly
different from those of traded  options,  and because  changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion,  the  existing  models do not  necessarily  provide a  reliable  single
measure of the fair value of its employee stock options.

For  purposes  of the pro forma  disclosure,  the  estimated  fair  value of the
options is amortized to expense over the options' vesting period.

The Company's pro forma information follows:

14.  Operating Leases

The Company  leases office space and  equipment  located  throughout  the United
States and worldwide,  all of which are under operating leases which expire over
the next seven years.

Substantially  all office space leases provide for the Company to pay a pro rate
share of annual  increases above a stated base amount of the landlords'  related
real estate taxes and operating expenses.  Management expects that in the normal
course of  business,  operating  leases  will be  renewed or  replaced  by other
operating leases.

The  following  is a schedule  by years of the future  minimum  rental  payments
required  under  the  operating   leases  that  have  an  initial  or  remaining
noncancellable lease term in excess of one year as of December 31, 1997:

Year ended December 31,
           1998 .............................................         $3,382,000
           1999 .............................................          3,681,000

Total rental  expense for the years ended  December 31, 1995,  1996 and 1997 was
approximately $2,033,000, $2,782,000 and $2,907,000, respectively.

15.  Retirement Plan

The Company  maintains  tax-deferred  savings plans under Section  401(k) of the
Internal Revenue Code to provide retirement  benefits for all eligible employees
(the "Plan").  Employees may voluntarily contribute a percentage of their annual
compensation to the Plan, subject to Internal Revenue Service  limitations.  The
Company may, but has no obligation to, make matching contributions. In addition,
the Company may, but has no obligation to, make a discretionary  contribution to
the Plan. Discretionary contributions are allocated to participants' accounts in
proportion to their compensation. The company's discretionary matching and other
contributions  for 1996 and 1997 were $1,384,000 and  $1,528,000,  respectively.

             Notes to Consolidated Financial Statements (Continued)
                           December 31, 1996 and 1997

16.  Commitments and Contingencies

Cost subject to audit

Under its United States government contracts, the Company is subject to audit by
the Defense Contract Audit Agency,  which could result in adjustments of amounts
previously billed.  Management believes that the results of such audits will not
have a material adverse effect on the Company's financial position or results of
operations.

Financial Instruments and Risk Management

The Company operates around the world principally in United States currency. The
Company may reduce any periodic  exposures to fluctuations  in foreign  exchange
rates by creating  offsetting  ("hedge") positions through the use of derivative
financial  instruments.  The Company currently does not use derivative financial
instruments for trading or speculative  purposes,  nor is the Company a party to
leverage  derivatives.  The Company  regularly  monitors  any  foreign  currency
exposures and ensures that hedge  contract  amounts do not exceed the amounts of
the underlying exposures.

The Company had no open hedge positions at December 31, 1996 and 1997.

Financial  instruments  that  potentially  subject  the  Company to  significant
concentrations  of credit risk consist  principally of cash and cash equivalents
and trade accounts receivable.

The  Company   maintains  cash  and  cash  equivalents  with  various  financial
institutions.  These  financial  institutions  are  located  in  many  different
countries  throughout the world,  and the Company's  policy is designed to limit
exposure with any one institution.  As part of its cash management process,  the
company performs  periodic  evaluations of the relative credit standing of these
financial institutions.

At December 31, 1996 and 1997,  respectively,  cash of approximately  $1,004,000
and $1,425,000 was located in foreign bank accounts.

Major Customers

At December 31, 1996 and 1997,  included in accounts  receivable  was $6,824,000
and $9,143,000, respectively, due from agencies of the United States government.
Credit risk with respect to the remaining trade accounts receivable is generally
diversified  due to the  large  number  of  entities  comprising  the  Company's
customer base and their dispersion  across  different  industries and countries.
The Company  performs  ongoing credit  evaluations  of its customers'  financial
condition.

The Company  generates  revenues from contracts with  governmental  agencies and
private companies within the United States and worldwide.  During 1995, 1996 and
1997,  the  Company  recognized  approximately,   $12,313,000,  $25,997,000  and
$31,792,000,  respectively,  of its revenue  from the United  States  Agency for
International  Development  ("USAID"),  a U.S.  government  agency,  and a major
public  utility.  Revenues  earned from foreign  customers,  both commercial and
governmental,  were  approximately  $713,000,  $1,314,000 and $6,831,000 for the
years ended December 31, 1995, 1996 and 1997, respectively.

17.  Pooling of Interests

In November of 1997,  the  Company  acquired  Apogee.  In  connection  with this
transaction,  Apogee shareholders  received 1.2689 shares of the Company's stock
for each Apogee share.  The Company

             Notes to Consolidated Financial Statements (Continued)
                           December 31, 1996 and 1997

issued  409,985  shares  of its  stock of all of  outstanding  shares  and stock
options of Apogee.  Apogee was founded in 1986, and provides consulting services
to the transportation and the environmental  sectors.  The merger qualified as a
tax-free  reorganization  and  was  accounted  for as a  pooling  of  interests.
Accordingly,  the Company's  financial  statements have been restated to include
the  results  of  Apogee  for all  periods  presented.  As Hagler  Bailly  began
operations on May 26, 1995,  the financial  statements  for all periods prior to
May 26, 1995 will be those of Apogee and TB&A.

     On February 23, 1998, the Company  completed the acquisition of TB&A Group,
Inc., and it's wholly-owned subsidiary,  Theodore Barry and Associates ("TB&A").
The  Company  issued  454,994  shares of  common  stock in  connection  with the
business  combination.  The  business  combination  will be  accounted  for as a
pooling of interests.  Accordingly, the Company's financial statements have been
restated to include the  results of TB&A for all  periods  presented.  As Hagler
Bailly  began  operations  on May 26, 1995,  the  financial  statements  for all
periods prior to May 26, 1995, will be those of Apogee and TB&A.

Combined  and  separate  results of Hagler  Bailly,  Apogee and TB&A  during the
periods preceding the merger were as follows (in millions):

                                  Hagler Bailly   Apogee       TB&A     Combined

conform accounting policies of the three companies.

Securities  and  Exchange  Commission  ("SEC")  and  do not  include  all of the
information  and note  disclosures  required by  generally  accepted  accounting
principles.  The information  furnished  herein reflects all  adjustments,  of a
normal recurring nature, which are, in the opinion of management,  necessary for
a fair presentation of results for these interim periods.

The interim results of operations are not necessarily  indicative of the results
to be expected for the entire fiscal year ending December 31, 1998.

As a result of the  pooling  of  interests  transaction  completed  in the first
quarter, as described in Note 3 below, all consolidated financial statements and
related schedules  presented for the three month period ended March 31, 1998 and
1997 and as of December  31,  1997 have been  restated to include the results of
operations and financial position of TB&A Group, Inc. These financial statements
should be read in conjunction with the Company's audited consolidated  financial
statements  and notes  thereto for the year ended  December  31,  1997  included
herein.

Note 2. Earnings per Share

Basic  earnings per share is computed  based on the weighted  average  number of
shares of common  stock  outstanding  during  the  respective  periods.  Diluted
earnings  per share is inclusive of the  dilutive  effect of  unexercised  stock
options using the treasury stock method.

Note 3. Pooling of Interests

On  February  23,  1998,  the  Company  completed  the  merger  of  one  of  its
wholly-owned subsidiaries with TB&A Group, Inc. and its wholly-owned subsidiary,
Theodore Barry & Associates  (collectively  "TB&A").  The Company issued 454,994
shares of its  common  stock in  connection  with the  merger and the merger was
accounted for as a  pooling-of-interests.  Accordingly,  the Company's financial
statements  have been  restated  to include  the results of TB&A for all periods
presented.

                         Report of Independent Auditors


Board of Directors and Shareholders
Putnam, Hayes & Bartlett, Inc. and Subsidiaries


We have audited the accompanying  consolidated balance sheets of Putnam, Hayes &
Bartlett,  Inc.  and  subsidiaries  as of December  31,  1997 and 1996,  and the
related consolidated  statements of operations,  shareholders'  equity, and cash
flows for each of the three  years in the period  then  ended.  These  financial
statements   are  the   responsibility   of  the   Company's   management.   Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects,  the consolidated  financial position of Putnam,  Hayes &
Bartlett,  Inc.  and  subsidiaries  at  December  31,  1997  and  1996,  and the
consolidated  results of their  operations  and their cash flows for each of the
three years in the period then ended,  in  conformity  with  generally  accepted
accounting principles.

                   Notes to Consolidated Financial Statements

                               December 31, 1997


1.  Summary of Significant Accounting Policies

Organization and Nature of Business

Putnam,  Hayes & Bartlett,  Inc.  (the Company) is a  Massachusetts  corporation
which renders  consulting  services to private and public clients on a worldwide
basis.  The  Company  provides  management  consulting,  advisory  and  economic
analysis  services in the areas of  business  strategy,  litigation  support and
expert  testimony and public policy.  The Company's  headquarters are located in
Cambridge,  Massachusetts  with offices in Washington  DC, and  California,  and
subsidiary offices in New Zealand and Australia.

Principles of Consolidation

The consolidated  financial  statements include the accounts of Putnam,  Hayes &
Bartlett, Inc. and its wholly-owned subsidiaries,  Putnam, Hayes & Bartlett-Asia
Pacific Limited acquired in April 1996 and Putnam, Hayes & Bartlett-Asia Pacific
Pty Ltd established in September 1997. The consolidated statements of income for
1996 and 1995 also  include  the  accounts of Putnam,  Hayes & Bartlett  Limited
which was  liquidated in December 1996 (see Note 2). All  intercompany  services
accounts and transactions are eliminated in consolidation.

In 1997, the Company acquired a 7.8% minority ownership interest in a consulting
business in the United Kingdom for cash of $531,432.  Due to the  uncertainty of
recovery,  the Company  has  provided  in  selling,  general and  administrative
expense a full valuation  allowance on this  investment as of December 31, 1997.
During 1997, the Company provided services to, and purchased consulting services
from,  this  consulting  business  of $37,767  and  $287,850,  respectively.  At
December  31,  1997,  the  accounts  receivable  from this  consulting  business
amounted to $135,078.

Revenue Recognition

Consulting  revenue is derived from services  provided by professional  staff of
the Company.  Subcontractor  and other  revenue  represent  revenue  principally
related to services provided by subcontractors  and billed by the Company to its
clients and also includes other reimbursable costs billed to clients. Consulting
services are principally  provided under time and material  contracts.  Revenues
under  these  contracts  are  recognized  in the period  the work is  performed.
Estimated  losses on  consulting  contracts  are  provided  for at the time such
losses become known.

1.  Summary of Significant Accounting Policies (continued)

Concentration of Credit Risk

The Company  provides it services to customers in a variety of  industries.  The
Company performs  continuing  credit  evaluations of its customers and generally
does not require  collateral.  Historically,  the  Company's  losses  related to
receivables  from  individual   customers  or  groups  of  customers  have  been
consistent  with its  estimates.  During  1997,  the Company  derived 12% of its
revenues from two customers,  and for 1996 and 1995, 20% and 19%,  respectively,
of its total revenues from two different customers.

The Company  maintains  its excess  cash  balances  in  highly-rated  short-term
investment  instruments.  The Company has not  experienced any losses from these
investments.

Cash Equivalents

The Company  considers  all highly liquid  investments  with a maturity of three
months or less when purchased to be cash equivalents.

Financial Instruments

The Company's financial instruments  principally include accounts receivable and
unbilled  services,  accounts  payable,  notes payable to bank under its line of
credit and long-term debt. The fair value of these instruments approximate their
carrying value based upon their short-term nature and variable rates on interest
bearing instruments.

Equipment and Improvements

Equipment and improvements are stated at cost. Depreciation is provided based on
the estimated  useful lives of the assets using a combination  of  straight-line
and accelerated methods. Furniture and fixtures, computer equipment and software
and communications  equipment are depreciated over periods ranging from three to
seven years and  leasehold  improvements  are  amortized  over the lesser of the
useful life or term of the lease.  Expenditures  for repairs and maintenance are
charged to operations as incurred.

Income Taxes

The Company  provides for income taxes under the  liability  method.  Under this
method,  deferred  taxes are based on the future  income tax effect of temporary
differences  between  the  book  and  tax  bases  of the  Company's  assets  and
liabilities,  assuming they will be realized and settled,  respectively,  at the
amount reported in the Company's financial statements.

             Notes to Consolidated Financial Statements (continued)


1.  Summary of Significant Accounting Policies (continued)

The  Company  uses the cash basis of  accounting  for income tax  purposes.  The
Company  does  not  provide  for  income  taxes  on  undistributed  earnings  of
subsidiaries, as such taxes are expected to be offset by foreign tax credits.

Foreign Currency Translation

The assets and liabilities of the Company's foreign  subsidiaries are translated
into U.S.  dollars using exchange  rates at the balance sheet dates.  Income and
expense  items are  translated  at  average  exchange  rates for the  respective
periods.  The effect of translating these amounts at different rates is included
in the foreign currency translation  adjustment account in shareholders' equity.
Transactions  gains and losses are  charged to  operations  and are  included in
other  income  (expense).  Transaction  losses  in 1997  amounted  to  $299,800.
Transaction gains in 1996 amounted to $240,200.  In 1995, these amounts were not
material.

Use of Estimates

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of assets  and  liabilities  and  disclosure  of
contingent  assets and  liabilities at the date of the financial  statements and
the  reported  amounts of revenues  and expenses  during the  reporting  period.
Management believes that estimates,  including the amount due in connection with
the  liquidation  of Putnam,  Hayes &  Bartlett  Limited,  and normal  recurring
provisions  and allowances  made in preparation of the financial  statements are
fairly presented. However, actual results could differ from estimates.

Impairment of Long-Lived Assets

In 1996, the Company adopted Statement of Financial  Accounting  Standard (SFAS)
No. 121,  "Impairment of Long-Lived  Assets and Long-Lived Assets to be Disposed
Of". SFAS No. 121 requires recognition of impairment losses on long-lived assets
when indicators of impairment losses on long-lived assets are present and future
undiscounted  cash flows are  insufficient  to  support  the  assets'  recovery.
Adoption  of SFAS  No.  121 did not  have a  material  impact  on the  Company's
financial statements.

1.  Summary of Significant Accounting Policies (continued)

Earnings Per Share

In 1997, the Company adopted SFAS No. 128,  "Earnings per Share".  SFAS No. 128,
which is applicable  only to public  companies,  simplifies  the  calculation of
earnings per share (EPS) and makes it  comparable to the new  international  EPS
standard.  It replaces the presentation primary EPS with a presentation of basic
EPS.  Unlike  primary  EPS,  basic EPS  excludes  options,  warrants,  and other
potentially  dilutive  securities  from  the  calculation.  The  Company  had no
dilutive securities outstanding during 1997, 1996 or 1995.

Basic EPS  excludes  dilution  and is computed by dividing  income  available to
common stockholders by the weighted-average  number of common shares outstanding
for the period.  Diluted EPS reflects the potential dilution that could occur if
securities or other  contracts to issue common stock were exercised or converted
into common  stock or resulted in the  issuance of common stock that then shared
in the  earnings of the  entity.  Diluted  EPS is  computed  similarly  to fully
diluted EPS.

Recent Pronouncements

In June 1997, SFAS No. 130,  "Reporting  Comprehensive  Income" was issued which
established  standards for reporting and display of comprehensive income and its
components   (revenues,   expenses,   gains  and   losses)  in  a  full  set  of
general-purpose financial statements. This statement requires that an enterprise
classify  items of other  comprehensive  income by their  nature in a  financial
statement  and display the  accumulated  balance of other  comprehensive  income
separately from retained  earnings and additional  paid-in capital in the equity
section of the balance  sheet.  This  statement  is  effective  for fiscal years
beginning  after  December 15, 1997.  The Company  believes that the adoption of
this statement will not materially  impact its financial  position or results of
operations.

In June 1997,  SFAS No. 131,  "Disclosure  about  Segments of an Enterprise  and
Related Information" was issued which established  standards for public business
enterprises to report  information about operating  segments in annual financial
statements and requires those  enterprises to report selected  information about
operating segments in interim financial reports issued to shareholders.  It also
establishes  the standards for related  disclosures  about products and service,
geographic areas and major customers.

             Notes to Consolidated Financial Statements (continued)


1.  Summary of Significant Accounting Policies (continued)

This Statement  requires that a public business  enterprise report financial and
descriptive  information about its reportable operating segments.  The financial
information  is required to be reported on the basis that it is used  internally
for evaluating  segment  performance  and deciding how to allocate  resources to
segments.  Operating  segments  are  components  of an  enterprise  about  which
separate financial  information is available that is evaluated  regularly by the
chief  operating  decision  maker in deciding how to allocate  resources  and in
assessing performance.  This statement is effective for financial statements for
periods  beginning  after  December  15,  1997.  The Company  believes  that the
adoption of this statement will not materially impact its financial  position or
results of operations.

The Company  intends to adopt  Statement of Financial  Accounting  Standards No.
132, "Employers' Disclosures about Pension and Other Postretirement Benefits" in
1998.  This standard  will require  additional  disclosure,  but will not have a
material effect on the Company's financial position or results of operations.

Stock-Based Compensation

The Company accounts for stock-based compensation  arrangements under Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" (APB
25) rather than the alternative fair value accounting  method provided for under
SFAS No. 123, "Accounting for Stock Based Compensation".  Under APB 25, when the
exercise price of options granted to employees and outside  directors  equals or
exceeds  the  market  value of the  underlying  stock on the date of  grant,  no
compensation  is required.  No options  were  granted in 1997,  1996 or 1995 and
accordingly, the disclosures required by SFAS No. 123 are not presented.

2.  Acquisition and Divestiture

On April 5, 1996, the Company  acquired all of the outstanding  stock of Putnam,
Hayes & Bartlett-Asia Pacific Limited (PHB-AP) in exchange for 150,000 shares of
the  Company's  common  stock and cash of  $10,100.  At that time  PHB-AP  had a
wholly-owned subsidiary,  CORE Management Systems Limited, which was amalgamated
into PHB-AP as of December 31,  1997.  PHB-AP,  located in New Zealand  provides
consulting  services to private and public  clients.  The  acquisition  has been
accounted  for under the  purchase  method  and,  accordingly,  the  assets  and
liabilities of PHB-AP at the

2.  Acquisition and Divestiture (continued)

acquisition  date have been stated at their fair value.  In accordance  with the
purchase  method,  the Company's  consolidated  statement of income includes the
operations  of  PHB-AP  from  April  5,  1996,  the  acquisition  date.  Had the
acquisition  occurred on January 1, 1996 the Company's  consolidated  results of
operations for the year ended  December 31, 1996 would not have been  materially
different.

On December 23, 1996, the Company caused Putnam,  Hayes & Bartlett  Limited (PHB
Ltd),  the  Company's  U.K.  subsidiary,  to cease  operations  and  appointed a
liquidator to wind up PHB Ltd's affairs.  The operating  results of PHB Ltd have
been  included  in the  Company's  consolidated  statement  of income  until the
liquidation  date. The Company  recognized the net amount due as of December 31,
1996 in  connection  with  the  liquidation  of PHB Ltd as a  current  asset  of
$2,171,701.  This amount represented  management's  estimate of the net proceeds
ultimately  expected to be recovered upon collection of accounts receivable from
clients and payment of  obligations  to creditors.  As of December 31, 1997, the
Company  estimates  that $328,070 of the $2,171,701 is not  collectible.  Of the
Company's loss of $662,609 recognized in 1996 in connection with the liquidation
of  its  UK  subsidiary,   $548,757  represented   cumulative  foreign  currency
translation losses which had previously been recorded as a separate component of
the Company's shareholders' equity.

3.  Bank Line of Credit

The Company has entered into a revolving  credit  agreement  (Agreement)  with a
bank which  enables the Company to borrow up to  $4,000,000,  subject to certain
restrictions  which  limit  the  borrowing  base  to  70% of  eligible  accounts
receivable,  plus 50% of the eligible unbilled accounts receivable,  less the US
dollar equivalent of  (pound)150,000.  The Agreement  requires the Company among
other things to maintain certain operating covenants.  At December 31, 1997, the
Company was in violation of these covenants for which waivers were obtained. The
Agreement  expires on May 31,  1998.  Interest  is charged at the greater of the
bank's Base Rate or the Federal  Funds  Effective  Rate plus 0.5%, as defined by
the Agreement.  The Company's accounts receivable are assigned as security under
the  Agreement.  The Agreement  requires a commitment fee of 0.5% on the average
daily amount of the unborrowed  portion of the commitment,  payable quarterly in
arrears. At December 31, 1997 and 1996, $2,500,000 and $2,600,000, respectively,
was unused on the revolving line of credit.

The  effective  tax rates in 1997,  1996 and 1995 are higher than the  statutory

travel, meals and entertainment expenses included in the statement of operations
for which the Company is not entitled to a tax deduction.

9.  Employee Stock Arrangements

Since October 1, 1984, all of the Company's common stock has been subject to the
terms and  conditions  of a Stock  Purchase  Agreement  (Agreement)  between the
Company and each of its  shareholders.  A premise of the  Agreement is to assure
that all  outstanding  stock of the  Company  remains in the hands and under the
control of persons actively engaged in the business of the Company.

The Company  sells shares of its common stock to senior level  employees who are
required  to  purchase  specified  amounts of shares  based upon the  employees'
respective  positions.  The  price  of the  stock is the book  value  per  share
determined  by the  Company's  most recently  issued  annual  audited  financial
statements.  Sale of stock to these  individuals  generally occurs shortly after
the issuance of the Company's  annual audited  financial  statements,  typically
within 120 days after year end. The Agreement  provides that upon termination of
employment  or death the Company is required to purchase all shares owned by the
former  employee at the book value per share of the Company  based upon the most
recently  available  audited financial  statements.  The Agreement also provides
that if a  shareholder  has  received  an offer to sell or desires  to  transfer
shares the Company has a right of first refusal to purchase those shares at book
value.  The  Agreement  provides for the purchase of shares by the Company to be
made in the  form of  cash,  promissory  notes or a  combination  thereof.  Such
purchases of stock by the Company occur periodically during the year as a result
of employment terminations.

Until August 1997,  the Company has  accounted  for the sale and purchase of its
common stock under the arrangements described above as capital transactions.  In
connection with the proposed  transaction  described in Note 13, under generally
accepted  accounting  principles,  stock  issued or  subject to  issuance  under
subscriptions receivable entered into within the 12 months preceding the closing
of the  transaction  are  presumed to have been issued in  contemplation  of the
proposed transaction and are required to be accounted for at their fair value at
the date of issuance.  Accordingly, the Company has recognized a noncash, nontax
deductible   compensation   charge  as  of  December  31,  1997  of  $9,884,800,
representing the difference  between the fair value and the book value of shares
of common stock issuable through December 31, 1997.

Profit  Sharing Plan is paid by the Company and amounted to $13,200 for 1997 and
$12,000 for 1996 and 1995, respectively.

401(k) Plan

Effective  August 1, 1994,  the Company  established a voluntary  401(k) savings
plan  (the  401(k)  Plan)  for  eligible  employees.  Participants  may elect to

federal  limitations.  The cost of administering  the 401(k) Plan is paid by the
Company and amounted to $6,300 for 1997, $6,000 for 1996 and $5,075 for 1995.

Personal Pension Scheme Contributions for Subsidiary Employees

11.  Compensation Arrangements

base salary,  a standard bonus based upon the achievement of specific  operating
objectives  and   performance   incentive   compensation   for   achievement  of
profitability in excess of these specific  operating  objectives.  These amounts
are  accrued  as earned  and paid in cash or  deferred  under  the  arrangements
described below.

The Company  has a Deferred  Compensation  Plan (the Plan) under which  eligible
principals,   directors  and  officers  of  the  Company  may,  and  in  certain
circumstances are required to defer receipt of certain bonus amounts  (otherwise
payable to them in cash) by so electing in accordance with the provisions of the
Plan.  Deferred  compensation  under the Plan is  converted  along with  accrued
interest  to a  non-transferable  interest  bearing  promissory  note  upon  the
participant's  separation from the Company.  Interest is calculated at the prime
rate (8.5% at December 31, 1997). All deferred bonuses have been accrued and are
classified  as  long-term  on the balance  sheet.  Interest  expense  related to
deferred  compensation  has been accrued and  amounted to $162,758,  $90,702 and
$27,533 for the years ended December 31, 1997, 1996 and 1995, respectively.

              PRO FORMA COMBINED CONSOLIDATED FINANCIAL STATEMENTS

     The  following   unaudited  pro  forma  combined   consolidated   financial
statements assume a business combination between Hagler Bailly and PHB accounted
for on a  pooling-of-interest  basis  and are based  on,  and  should be read in
conjunction with, the respective  historical  consolidated  financial statements
and the notes thereto of Hagler Bailly and PHB, which are included as annexes to
this Joint Proxy Statement/PPM.

     For  purposes  of the  preparation  of the  unaudited  pro  forma  combined
consolidated   balance   sheet,   no  estimate  is  used  for  the  sum  of  the
merger-related  expenses (which the companies  anticipate will be  approximately
$2.0  million)  and no  deferred  tax  benefit  relating  to these  expenses  is
included.

     The pro forma combined consolidated  financial statements are presented for
illustrative  purposes only and are not necessarily  indicative of the operating
results or financial  position  that would have been  achieved if the Merger had
been  consummated  as of the  beginning of the periods  presented,  nor are they
necessarily  indicative of the future operating results or financial position of
Hagler Bailly/PHB.  The pro forma combined  consolidated  financial  information
does not give effect to any cost savings  which may result from the  integration
of Hagler Bailly's and PHB's operations.

RIGHTS.--The notice of the meeting of stockholders at which the approval of such
proposed  action is to be considered  shall contain a statement of the rights of
objecting stockholders.  The giving of such notice shall not be deemed to create
any  rights in any  stockholder  receiving  the same to demand  payment  for his

statement of opinion by the management as to the existence or  non-existence  of
the right of the  stockholders  to demand  payment for their stock on account of
the proposed  corporate action.  The notice may be in such form as the directors
or officers calling the meeting deem advisable, but the following form of notice

eighty-six  and whose  shares  were not voted in favor of the  approval  of such
action,  that the action  approved at the meeting of the corporation of which he
is a stockholder  has become  effective.  The giving of such notice shall not be
deemed to create  any  rights in any  stockholder  receiving  the same to demand
payment for his stock. The notice shall be sent by registered or certified mail,
addressed  to the  stockholder  at his last  known  address as it appears in the
records of the corporation.

89 DEMAND FOR PAYMENT BY OBJECTING STOCKHOLDER.--If within twenty days after the

corporation  upon which  such  demand is made shall pay to him the fair value of
his stock within  thirty days after the  expiration  of the period  during which
such demand may be made.

90 DETERMINATION OF VALUE OF STOCK BY SUPERIOR  COURT.--If  during the period of
thirty days provided for in section  eighty-nine the corporation upon which such
demand is made and any such objecting  stockholder fail to agree as to the value
of such stock,  such  corporation or any such stockholder may within four months
after the expiration of such  thirty-day  period demand a  determination  of the
value of the stock of all such objecting  stockholders by a bill in equity filed
in the  superior  court in the  county  where  the  corporation  in  which  such
objecting  stockholder  held  stock  had  or has  its  principal  office  in the
commonwealth.

stockholders  who have  demanded  payment  for  their  shares  and with whom the
corporation  has not reached  agreement as to the value thereof.  If the bill is
filed by a stockholder,  he shall bring the bill in his own behalf and in behalf
of all other  stockholders  who have demanded  payment for their shares and with
whom the  corporation  has not reached  agreement as to the value  thereof,  and
service of the bill shall be made upon the  corporation  by subpoena with a copy
of the bill annexed.  The corporation shall file with its answer a duly verified
list of all such other  stockholders,  and such stockholders  shall thereupon be
deemed to have been  added as parties to the bill.  The  corporation  shall give
notice in such form and returnable on such date as the court shall order to each
stockholder party to the bill by registered or certified mail,  addressed to the
last  known  address  of  such  stockholder  as  shown  in  the  records  of the
corporation,  and the court may order such  additional  notice by publication or
otherwise as it deems  advisable.  Each stockholder who makes demand as provided
in section  eighty-nine  shall be deemed to have  consented to the provisions of
this section relating to notice,  and the giving of notice by the corporation to
any such  stockholder  in  compliance  with the  order of the  court  shall be a
sufficient  service of process on him. Failure to give notice to any stockholder
making demand shall not invalidate the  proceedings as to other  stockholders to
whom notice was properly  given,  and the court may at any time before the entry
of a final decree make supplementary orders of notice.

92 BILL IN EQUITY  TO  DETERMINE  VALUE OF STOCK OF  OBJECTING  STOCKHOLDERS  ON
FAILURE TO AGREE ON VALUE  THEREOF,  ETC; ENTRY OF DECREE  DETERMINING  VALUE OF
STOCK; DATE ON WHICH VALUE IS TO BE  DETERMINED.--After  hearing the court shall
enter a decree determining the fair value of the stock of those stockholders who
have become entitled to the valuation of and payment for their shares, and shall
order the corporation to make payment of such value,  together with interest, if
any, as hereinafter  provided,  to the  stockholders  entitled  thereto upon the
transfer by them to the corporation of the certificates  representing such stock
if   certificated  or  if   uncertificated,   upon  receipt  of  an  instruction
transferring such stock to the corporation.  For this purpose,  the value of the
shares  shall  be  determined  as of the day  preceding  the  date  of the  vote
approving the proposed corporate action and shall be exclusive of any element of
value arising from the expectation or accomplishment  of the proposed  corporate
action.

93 BILL IN EQUITY  TO  DETERMINE  VALUE OF STOCK OF  OBJECTING  STOCKHOLDERS  ON
FAILURE TO AGREE ON VALUE THEREOF,  ETC.; COURT MAY REFER BILL, ETC., TO SPECIAL
MASTER TO HEAR PARTIES,  ETC.--The court in its discretion may refer the bill or
any question  arising  thereunder to a special master to hear the parties,  make
findings  and  report the same to the court,  all in  accordance  with the usual
practice in suits in equity in the superior court.

94 BILL IN EQUITY  TO  DETERMINE  VALUE OF STOCK OF  OBJECTING  STOCKHOLDERS  ON
FAILURE TO AGREE ON VALUE THEREOF,  ETC.; STOCKHOLDER PARTIES MAY BE REQUIRED TO
SUBMIT  THEIR  STOCK  CERTIFICATES  FOR  NOTATION  THEREON OF  PENDENCY OF BILL,
ETC.--On  motion the court may order  stockholder  parties to the bill to submit
their  certificates  of stock to the  corporation  for  notation  thereon of the
pendency of the bill, and may order the corporation to note such pendency in its
records  with  respect to any  uncertificated  shares  held by such  stockholder
parties,  and may on motion dismiss the bill as to any  stockholder who fails to
comply with such order.

95 BILL IN EQUITY  TO  DETERMINE  VALUE OF STOCK OF  OBJECTING  STOCKHOLDERS  ON
FAILURE TO AGREE ON VALUE THEREOF,  ETC.;  TAXATION OF COSTS, ETC.;  INTEREST ON
AWARD,  ETC.--The costs of the bill,  including the reasonable  compensation and
expenses of any master  appointed by the court, but exclusive of fees of counsel
or of experts retained by any party,  shall be determined by the court and taxed
upon the  parties to the bill,  or any of them,  in such manner as appears to be
equitable, except that all costs of giving notice to stockholders as provided in
this chapter shall be paid by the  corporation.  Interest shall be paid upon any
award from the date of the vote approving the proposed corporate action, and the
court


                                      F-2
<PAGE>

may on application of any interested  party  determine the amount of interest to
be paid in the case of any stockholder.

96  STOCKHOLDER   DEMANDING   PAYMENT  FOR  STOCK  NOT  ENTITLED  TO  NOTICE  OF
STOCKHOLDERS'  MEETINGS  OR  TO  VOTE  STOCK  OR  TO  RECEIVE  DIVIDENDS,  ETC.;
EXCEPTIONS.--Any  stockholder who has demanded payment for his stock as provided
in this  chapter  shall not  thereafter  be entitled to notice of any meeting of
stockholders  or to vote such stock for any purpose and shall not be entitled to
the payment of dividends or other distribution on the stock (except dividends or
other  distributions  payable to stockholders of record at a date which is prior
to the date of the vote approving the proposed  corporate action) unless:  (1) A
bill shall not be filed within the time provided in section ninety;  (2) A bill,
if filed,  shall be dismissed as to such  stockholder;  or (3) Such  stockholder
shall  with  the  written  approval  of the  corporation,  or in the  case  of a
consolidation or merger, the resulting or surviving corporation, deliver to it a
written  withdrawal of his  objections  to and an  acceptance of such  corporate
action.

Notwithstanding  the  provisions  of  clauses  (1)  to  (3),   inclusive,   said
stockholder  shall have only the rights of a  stockholder  who did not so demand
payment for his stock as provided in this chapter.

97 CERTAIN  SHARES PAID FOR BY  CORPORATION  TO HAVE  STATUS OF TREASURY  STOCK,
ETC.--The shares of the corporation paid for by the corporation  pursuant to the
provisions  of this  chapter  shall have the status of treasury  stock or in the
case of a consolidation  or merger the shares or the securities of the resulting
or surviving  corporation  into which the shares of such  objecting  stockholder
would have been  converted had he not objected to such  consolidation  or merger
shall have the status of treasury stock or securities.

98 ENFORCEMENT  BY STOCKHOLDER OF RIGHT TO RECEIVE  PAYMENT FOR HIS SHARES TO BE
EXCLUSIVE REMEDY;  EXCEPTION.--The  enforcement by a stockholder of his right to
receive  payment for his shares in the manner  provided in this chapter shall be
an exclusive remedy except that this chapter shall not exclude the right of such
stockholder to bring or maintain an  appropriate  proceeding to obtain relief on
the ground that such corporate  action will be or is illegal or fraudulent as to
him.
