         ARTICLE 4  REPRESENTATIONS AND WARRANTIES OF THE
                        ALLEN SHAREHOLDERS

     Each  Allen  Shareholder  represents  and  warrants to and agrees with
UNIFAB and Sub, as of the date hereof, as follows:

     Section 1.b OWNERSHIP AND TRANSFER OF SHARES.   (a)  He  is the lawful
owner  of  the  number of shares of Allen Common Stock listed opposite  his
name in SCHEDULE  4.8  hereto,  free  and clear of all Liens, encumbrances,
restrictions and claims of every kind; (b) he has the absolute legal right,

     Section  2.b  INVESTMENT REPRESENTATIONS.  (a)  Each Allen Shareholder
other than Porter is  acquiring  shares  of  UNIFAB  Common  Stock pursuant
hereto  for investment for his own account and has no present intention  of
reselling  or  otherwise distributing or participating in a distribution of
such shares; (b)  he  understands  that  such shares will not be registered
under the Securities Act, that such shares  will be "restricted securities"
as that term is used in Rule 144 of the SEC under the Securities Act ("Rule

subsequently registered under the Securities  Act  and under any applicable
state securities law or are transferred in a transfer  that  is exempt from
such registration; (c) except as otherwise contemplated by Section  8.3(e),
UNIFAB is not obligated by this Agreement to register such shares under the

to  the  transfer of any such shares, require that the request for transfer
be accompanied by an opinion of counsel, in form and substance satisfactory
to UNIFAB,  to  the  effect that the proposed transfer does not result in a
violation of the Securities  Act  or  any  applicable state securities law,
unless such transfer is covered by an effective registration statement; and
(d) such shares of UNIFAB Common Stock may not be sold publicly in reliance
on the exemption from registration under the  Securities  Act  afforded  by

     Section  3.b  REPRESENTATION; UNIFAB DISCLOSURE DOCUMENTS.  Each Allen
Shareholder,  together   with   the  other  Allen  Shareholders,  has  been
represented by competent and experienced  legal  counsel in connection with
the  negotiation  and  execution of this agreement, has  been  granted  the
opportunity to make a thorough  investigation  of and to obtain information
with respect to the business and affairs of UNIFAB, and has availed himself
of  such  opportunity either directly or through legal  counsel  and  other
authorized  representatives.   Each  Shareholder  acknowledges  that he has
received  from UNIFAB and has reviewed with his representatives a  copy  of
each  of the  following  documents  (the  "UNIFAB  Disclosure  Documents"):

contemplated by this Agreement as he or his representatives have requested.

     Section  4.b  RESTRICTIVE LEGEND.  Each Allen Shareholder  understands
and agrees that all  certificates  evidencing shares of UNIFAB Common Stock
to  be  issued  to  him  hereunder  will  bear   restrictive   legends   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 any applicable  state  law, and may not be transferred
     without registration under the Act  and  any such state law or an
     opinion of counsel satisfactory to the issuer  of such securities
     that registration is not required.

     Section 5.b UNIFAB RELIANCE.  Each Allen Shareholder  understands that
UNIFAB  in  issuing  the  shares  of UNIFAB Common Stock pursuant  to  this
Agreement  is  relying  upon,  among  other  things,  the  representations,
warranties and agreements contained in this Article in concluding that such
issuance does not require compliance with  the registration requirements of
the Securities Act.

     Section  6.b  ORGANIZATION.   Allen is a corporation  duly  organized,
validly existing and in good standing  under  the  laws  of  the  State  of
Louisiana  and  has  all  corporate  power  and  authority  to carry on its
business as now being conducted and to own its properties.  Allen  is  duly
qualified  to do business and is in good standing in each state and foreign
jurisdiction  in which the character or location of the properties owned or
leased by it or  the  nature  of  the  business  conducted by it makes such
qualification necessary, except those jurisdictions,  if  any, in which the
failure to be so qualified would not have, in the aggregate  for  all  such
jurisdictions,  a Material Adverse Effect; provided, however, that no Allen
Shareholder shall  be  deemed in breach of this representation with respect
to any such failure if the  Allen  Shareholders indemnify and hold harmless
UNIFAB against any loss arising out of such failure.

     Section  7.b  AFFILIATED  ENTITIES.    Allen  does  not,  directly  or
indirectly, own of record or beneficially, or  have the right or obligation
to  acquire,  any  outstanding  securities  or  other   interest   in   any
corporation, partnership, joint venture or other entity.

     Section  8.b  CAPITALIZATION.  The  authorized  capital stock of Allen
consists  exclusively of 1,000 shares of common stock,  no  par  value  per
share, of which  1,000  shares  are  issued and outstanding and held by the
Allen Shareholders in the respective amounts set forth on SCHEDULE 4.8, and
- -0- shares are held in its treasury.   All  of  such issued and outstanding
shares have been validly issued, are fully paid and  nonassessable and were
issued in compliance with any rights of first refusal,  in  compliance with
all  legal requirements and, except as set forth in SCHEDULE 4.8,  free  of
preemptive  rights.  No share of capital stock of Allen has been, or may be
required to be,  reacquired  by  Allen  for  any  reason  or  is, or may be
required  to  be,  issued  by  Allen  for  any  reason,  including, without
limitation, by reason of any option, warrant, security or right convertible
into or exchangeable for such shares, or any agreement to  issue any of the
foregoing.  No shares of Allen Common Stock have been issued  to or held by
any person who is not an Allen Shareholder.

     Section  9.b  AUTHORITY; ENFORCEABLE AGREEMENTS.  (a)  Allen  has  the
requisite corporate power and authority to enter into this Agreement and to
consummate the transactions  described  herein.  The execution and delivery
of  this  Agreement  by  Allen  and  the  consummation   by  Allen  of  the
transactions  described herein have been duly authorized by  all  necessary
corporate action  on  the  part  of  Allen,  including  without  limitation
approval of this Agreement by Allen's Board of Directors in accordance with
Section  112  of  the  LBCL, the approval thereof by the Allen Shareholders
being evidenced by their execution of this Agreement.

          (b)  This Agreement has been duly executed and delivered by Allen
and its shareholders, and  constitutes  a  valid  and binding obligation of
Allen,   enforceable  in  accordance  with  its  terms,  except   as   such
enforceability  may be limited by bankruptcy, insolvency, reorganization or
similar laws affecting  creditors' rights generally or by general equitable
principles. The other agreements  entered,  or to be entered, into by Allen
in connection with this Agreement have been,  or will be, duly executed and
delivered by Allen, and constitute, or will constitute,  valid  and binding
obligations of Allen, enforceable in accordance with their terms, except as
such   enforceability   may   be   limited   by   bankruptcy,   insolvency,
reorganization or similar laws affecting creditors' rights generally  or by
general equitable principles.

     Section  10.b NO CONFLICTS OR CONSENTS.   (a)  Except as set forth  on
SCHEDULE 4.10(A),  neither  the  execution, delivery or performance of this
Agreement by Allen nor the consummation  of  the  transactions contemplated
hereby will violate, conflict with, or result in a  breach of any provision
of, constitute a default (or an event that, with notice or lapse of time or
both, would constitute a default) under, result in the  termination  of, or
accelerate  the  performance  required by, or result in the creation of any
adverse claim against any of the  properties  or assets of Allen under, (i)
the  articles  of  incorporation,  by-laws  or  any  other   organizational
documents  of  Allen,  (ii)  any note, bond, mortgage, indenture,  deed  of
trust, lease, license, agreement or other instrument or obligation to which
Allen is a party, or by which  Allen  or  any  of  its assets are bound, or
(iii)  any  order,  writ, injunction, decree, judgment,  statute,  rule  or
regulation of any governmental  body  to which Allen is subject or by which
Allen or any of its assets are bound (an  "Applicable  Law")  which  would,
individually or in the aggregate, have a Material Adverse Effect.

          (b)  No   consent   or   approval   of,  any  court,  commission,
governmental body, regulatory agency, authority,  political  subdivision or
tribunal (a "Governmental Entity") is required by or with respect  to Allen
or  any Allen Shareholder in connection with the execution and delivery  of
this Agreement by Allen, or is necessary for the consummation of the Merger
and the  other transactions contemplated by this Agreement, except for: (i)
the filing  and  recordation  requirements  of the LBCL with respect to the
Certificate  of  Merger and the filing of appropriate  documents  with  the
relevant authorities  of  other  states  in  which Allen is qualified to do
business,   and   (ii)   such   other  consents,  orders,   authorizations,
registrations, declarations and filings  the  failure of which to obtain or
make would not, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect on Allen and would not materially impair the
ability  of  Allen  to  perform its obligations hereunder  or  prevent  the
consummation of any of the transactions contemplated hereby.

     Section 11.b CORPORATE  FORMALITIES;  CORPORATE DOCUMENTS, SHAREHOLDER
AGREEMENTS AND BOARD OF DIRECTORS.  (a)  Allen  has maintained its separate
corporate  existence,  has  substantially  complied  with   all   necessary
corporate formalities, has not commingled funds with any other Person,  and
has  substantially  complied  with  all other similar requirements so as to
maintain its separate existence in any  action  asserting that Allen is the
alter  ego of any Person, for piercing of the corporate  veil  or  for  any
other similar action.

its articles of incorporation and by-laws,  as  amended or restated through

hereunder  would  not  require  the interruption of  existing  services  or
materially  interfere  with  customer   relationships,  Allen  shall  fully
cooperate in affording access to its physical  premises  in order to permit
UNIFAB  or its agents to ascertain the general environmental  condition  of

Shareholders that UNIFAB intends to account for the Merger as a pooling-of-
interests under generally accepted accounting  principles.  UNIFAB has also
informed the Allen Shareholders that its ability  to account for the merger
as  a pooling-of-interests was a material factor considered  by  UNIFAB  in
UNIFAB's  decision  to  enter  into this Agreement.  Therefore, pursuant to
generally accepted accounting principles,  prior  to  the  publication  and
dissemination  by  UNIFAB  of  consolidated financial results which include
results of the combined operations  of the Surviving Company and UNIFAB for
at least 30 days on a consolidated basis  following the Effective Time, the
Allen Shareholders shall not sell, offer to  sell, or otherwise transfer or
dispose of, any of the Merger Consideration received by Allen Shareholders.
The certificates evidencing the Merger Consideration  to be received by the
Allen Shareholders will bear a legend substantially in  the  form set forth
in Section 4.4 hereof.

     Section   2.b   TAX-FREE   REORGANIZATION.    UNIFAB   and  the  Allen
Shareholders are entering into this Agreement with the intention  that  the
Merger qualify as a tax-free reorganization for federal income tax purposes
and  neither  the  Allen Shareholders nor UNIFAB will take any actions that
disqualify the Merger for such treatment.

     Section 3.b RELEASE AND INDEMNIFICATION OF WILLIAM A. HINES.  Promptly
after Closing, and in  no  event  later  than three business days after the
Closing Date, UNIFAB shall have released those  items reflected on SCHEDULE
7.3 as obligations of William A. Hines.  UNIFAB hereby  agrees to indemnify
and hold harmless William A. Hines from any and all liabilities,  costs and
expenses whatsoever, including without limitation reasonable attorneys fees
and costs, arising from any enforcement, threatened enforcement or attempts
to enforce the aforementioned obligations against William A. Hines.

     Section  4.h  WAIVER  OF  CONDITIONS.   Any  condition  to  a  party's

         ARTICLE 9  SURVIVAL OF REPRESENTATIONS; INDEMNITY

     Section 1.h POST-CLOSING REMEDIES.  After the Effective Time,  in  the
absence  of  fraud,  the  provisions of this Article 9 shall constitute the
exclusive remedies of the parties  for any breach of or non-compliance with
any of the representations, warranties  or  agreements set forth in Article
4, Article 5 or any certificate delivered pursuant  to  Section  8.2(f)  or
Section 8.3(d) of this Agreement.

     Section   2.h   INDEMNIFICATION  BY  ALLEN  SHAREHOLDERS.   The  Allen
Shareholders agree to  indemnify,  defend, protect and hold harmless UNIFAB
and Sub, at all times from and after  the  Effective Time, from and against
all  claims,  damages, actions, suits, proceedings,  demands,  assessments,
adjustments, costs  and  expenses  (including but not limited to reasonable
attorneys'  fees and expenses of investigation)  (collectively,  "Damages")
incurred by either of them as a result of or incident to any breach or non-
fulfillment of  any  representation, warranty or agreement made by Allen or
the Allen Shareholders  in  Article 4 or any certificate delivered pursuant
to Section 8.2(f) hereof; provided,  however,  that in the absence of fraud
the sole remedy of UNIFAB and Sub for indemnification  hereunder for breach
or  non-fulfillment  of  any  such representation, warranty,  agreement  or
certificate shall be recourse by  UNIFAB  and  Sub to the Escrow Shares and
Escrow Cash pursuant to Sections 9.4 and 9.5; and  provided,  further, that
each Allen Shareholder agrees  to remain personally obligated to  indemnify
and  hold harmless UNIFAB and Sub for Damages caused by the breach or  non-
fulfillment  of  a  representation,  warranty  or  agreement made by him in
Section 4.1 or Section 4.2 without limitation as to either time or amount.

     Section 3.h INDEMNIFICATION BY UNIFAB.  UNIFAB  covenants  and  agrees
that  it  will  indemnify,  defend,  protect  and  hold harmless each Allen
Shareholder  at  all  times  from and after the Effective  Time,  from  and
against all Damages incurred by  such  Allen  Shareholder as a result of or
incident to any breach or non-fulfillment of any  representation,  warranty
or  agreement of UNIFAB or Sub set forth in Article 5 or in any certificate
delivered  pursuant  to  Section  8.3(d);  provided,  however,  that in the
absence  of  fraud UNIFAB shall not have liability to any Allen Shareholder
under this Section  9.3 for Damages that in the aggregate exceed the sum of
(i) 10% of the value  of  the  shares of UNIFAB Common Stock issued to such
Assenting Allen Shareholder in connection with the Merger, such value to be
determined on the basis of the closing  price  of  UNIFAB  Common  Stock as
reported  by NASDAQ on the last Business Day prior to the date on which  it
is determined  that  an  amount  is to be paid pursuant to Section 9.4, and
(ii) the Escrow Cash (the "Indemnity Value").

     Section 4.h PROCEDURES.  (a)  Any party claiming indemnity for Damages
under this Article 9 (the "Indemnified  Party") shall give prompt notice to
the party by whom such indemnity is owed  (the "Indemnifying Party") of the
occurrence of any such Damages and of the nature  and  amount  thereof (the
"Indemnity Claim"); provided however, that no party may claim indemnity for
damages  under  this  Article  9 unless an Indemnity Claim (or two or  more
Indemnity Claims in the aggregate)  exceeds  $50,000.   No  notice  of  any
Indemnity  Claim  may  be  given  after the Escrow Termination Date and any
Indemnity Claim given after such date  shall  be  void  and  of no force or
effect.   The  Indemnifying  Party shall respond in writing to such  notice
within ten Business Days from  the  date  that  such notice of an Indemnity
Claim is received to either (i) accept the Indemnity  Claim  as  subject to
the  indemnities provided hereunder, or (ii) challenge the Indemnity  Claim
on the  basis  of either (A) the merits, or (B) the amount of the Indemnity
Claim.  If the Indemnifying Party fails to respond within ten Business Days
of receipt of the notice provided for herein, such failure to respond shall
be  deemed  acceptance  under  clause  (i)  of  the  immediately  preceding
sentence.  Any Indemnity Claim so accepted by UNIFAB shall be promptly paid
in cash, subject  to  the  limitations  set  forth  in  Section  9.3.   Any
Indemnity  Claim  so  accepted  by or on behalf of one or more of the Allen
Shareholders shall be paid as provided in Section 9.5.

          (b)  If the Indemnifying  Party  challenges  the  Indemnity Claim
under  Section  9.4(a)   above,  the  parties shall attempt to resolve  the
challenge through negotiation in good faith.  If the matter is not resolved
within ten Business Days after notice of the Indemnifying Party's challenge
is received by the Indemnified Party, either  party  may submit such matter
to  a  single  arbitrator.  The arbitrator will be selected  by  the  joint
agreement of the  parties, but if they do not agree within 20 calendar days
of  the  lapse of the  ten-Business  Day  period  referred  to  above,  the
selection shall be made in accordance with the Commercial Arbitration Rules
of  the  American  Arbitration  Association  (the  "Rules").   If  no  such
arbitrator is appointed within 45 calendar days of any such request to such
association,  either party may apply to a court having jurisdiction to make
such appointment.   The  arbitrator  shall  conduct  the arbitration in the
Parish  of  Iberia, State of Louisiana, in accordance with  the  Rules  and
shall make a  final determination, to be provided in writing to each party,
that resolves the  dispute.   The  prevailing  party  shall  be entitled to
recover   from  the  other  party  the  fees  of  the  arbitrator  and  the
administrative  costs  of  the arbitration.  The arbitrator shall apply the
statutory and decisional law of the State of Louisiana in substantially the
same manner as do the courts  of  the  State  of  Louisiana  in the case of
contracts made and wholly performed within that jurisdiction.   All results
of the arbitration proceeding shall be final, conclusive and binding on all
parties to this Agreement, and judgment upon the arbitrator's award  may be
entered   in   any  court  of  the  State  of  Louisiana  having  competent
jurisdiction, unless  such  results  or  award are clearly erroneous on the
record before the arbitrator.  In the event  of  an  arbitration  award  in
favor  of  the  Indemnified Party, if the Indemnifying Party is (i) UNIFAB,
such arbitration award shall be paid in cash, subject to the limitations in
Section  9.3,  or  (ii)  one  or  more  of  the  Allen  Shareholders,  such
arbitration award shall be paid as provided in Section 9.5.

     Section 5.h ESCROW  PROCEDURES.   (a)   At or after the Effective Time
and upon surrender by an Allen Shareholder of his certificates representing
his shares of Allen Common Stock pursuant to the provisions of Section 3.2,
UNIFAB shall retain the Escrow Shares or Escrow  Cash,  as the case may be,
in  escrow to secure the indemnification provided under Section  9.2  above
until  the  later  of  the  Escrow  Termination Date or the Extended Escrow
Termination Date.

          (b)  In all matters pertaining  to the indemnification provisions
of this Agreement and the disposition of the  Escrow  Shares  in connection
therewith,  each  Allen  Shareholder  hereby  appoints  and names Frank  J.
Cangelosi,  Jr.  (or such other Person as shall hereafter be  appointed  in
writing by the Allen  Shareholders  holding  a  majority of the outstanding
shares of Allen Common Stock immediately before the  Effective  Time and as
shall   consent   in  writing  to  such  appointment),  as  his  authorized
representative (the  "Allen  Shareholder  Representative"),  and  vests the
Allen Shareholder Representative with full power and authority to give  and
receive  notices and otherwise act on his behalf with regard to all matters
arising under this Article 9.

          (c)  In  the  event  of  an  Indemnity  Claim  that is either (i)
accepted by the Allen Shareholder Representative, or (ii) the subject of an
arbitration  award  pursuant to Section 9.4(b) in favor of UNIFAB  or  Sub,
UNIFAB shall (A) cause  a  number of Escrow Shares to be canceled such that
the value of the canceled Escrow  Shares,  valued  at  the Indemnity Value,
shall equal the lesser of (x) 91% of the amount of the Indemnity  Claim, or
(y)  the  aggregate  value  of the Escrow Shares, and (B) reduce the Escrow
Cash by an amount that is the  lesser  of (x) 9% of the Indemnity Claim, or
(y) the Escrow Cash plus accrued interest  thereon,  if  any.  In the event
Escrow Shares are canceled in accordance with subsection (ii)(A)(x) of this
Section  9.5(c),  such Escrow Shares shall be canceled pro rata  among  the
Assenting Allen Shareholders.

          (d)  The  date  of issuance of the first independent audit report
of the combined results of UNIFAB and Sub following the Merger shall be the
"Escrow Termination Date."

          (e)  The date upon  which an Indemnity Claim that is not resolved
as  of  the  Escrow  Termination  Date,  of  which  the  Allen  Shareholder
Representative or UNIFAB, as the case  may be, receives notice on or before
the Escrow Termination Date, is either (i)  resolved  pursuant  to  Section
9.4(a)  hereof,  or  (ii)  the  subject of an arbitration award pursuant to
Section 9.4(b) hereof, shall be the "Extended Escrow Termination Date."

          (f)  At the Escrow Termination  Date  UNIFAB shall (i) cancel the
number  of  Escrow Shares, if any,  necessary to satisfy  Indemnity  Claims
pursuant to Section  9.5(c)  hereof  and  distribute  the Escrow Shares not
canceled to each of the Assenting Allen Shareholders in  the  name  of whom
the  Escrow Shares are issued, and (ii) reduce the Escrow Cash by an amount
necessary to satisfy Indemnity Claims pursuant to Section 9.5(c) hereof and
distribute the remaining Escrow Cash plus accrued interest thereon, if any,
to Porter in cash.  Notwithstanding the provisions of the first sentence of
this clause  (f),  however,  in the event an Indemnity Claim is received by
UNIFAB or the Allen Shareholder  Representative,  as the case may be, on or
before the Escrow Termination Date and at the Escrow  Termination  Date  is
not  either  (A) satisfied in accordance with Section 9.5(c) hereof, or (B)
the subject of  an  arbitration  award  sustaining a challenge by the Allen
Shareholder Representative, UNIFAB  shall  retain  in  safekeeping from the
Escrow Shares that are not canceled in accordance with the  first  sentence
of this clause (f) and the remaining Escrow Cash until the Extended  Escrow
Termination  Date  a  number  of Escrow Shares and an amount of Escrow Cash
that  will,  in  its  discretion, be  sufficient  to  satisfy  the  pending
Indemnity Claim in the  event  it  is  satisfied pursuant to Section 9.5(c)
hereof and distribute the balance of the  Escrow  Shares  to  the Assenting
Allen Shareholders and the balance of the Escrow Cash plus accrued interest
thereon, if any, to Porter.  At the Extended Escrow Termination Date UNIFAB
shall (w) cancel the number of retained Escrow Shares, if any, necessary to
satisfy   91%   of   the   pending  Indemnity  Claim  pursuant  to  Section
9.5(c)(i)(A), (x) deliver the  remaining  retained  Escrow  Shares  to  the
Assenting  Allen  Shareholders,  (y)  reduce the retained Escrow Cash by an
amount necessary to satisfy 9% of the pending  Indemnity  Claims,  and  (z)
distribute  the  remaining  retained  Escrow  Cash  plus  accrued  interest
thereon, if any, to Porter.

          (g)  Each  Allen  Shareholder  will  deliver  to  UNIFAB   at the
Closing,  with respect to the Merger Shares, an executed stock power naming
UNIFAB attorney-in-fact  for such Allen Shareholder for the transfer of the
Merger Shares.

                      ARTICLE 10  TERMINATION

     Section 1.h TERMINATION.   This  Agreement  may  be terminated and the
Merger contemplated herein abandoned at any time before the Effective Time,
whether before or after approval by the shareholders of  Allen or UNIFAB as
follows:

          (a)  MUTUAL CONSENT.  By the mutual consent of Allen and UNIFAB.

          (b)  MATERIAL BREACH.  By the Board of Directors  of either Allen
or  UNIFAB  if  there  has  been  a  material  breach  by the other of  any
representation or warranty contained in this Agreement or  of  any covenant
contained  in  this Agreement, which in either case cannot be, or  has  not
been, cured within  15 days after written notice of such breach is given to
the party committing  such  breach,  provided that the right to effect such
cure shall not extend beyond the date set forth in subparagraph (c) below.

          (c)  ABANDONMENT.  By  the Board  of Directors of either Allen or
UNIFAB if (i) all conditions to Closing required  by  Article 8 hereof have
not  been  met  by or waived by the Closing Date, (ii) any  such  condition
cannot be met by  such  date and has not been waived by each party in whose
favor such condition inures,  or  (iii) the Merger has not occurred by such
date; provided, however, that neither Allen nor UNIFAB shall be entitled to
terminate this Agreement pursuant to this subparagraph (c) if such party is
in  material  violation  of  any  of  its  representations,  warranties  or
covenants in this Agreement.

          (d)  GOVERNMENT ACTION.  If any governmental authority shall have
issued an order, decree or ruling or taken  any  other  action  permanently
enjoining, restraining or otherwise prohibiting the Merger and such  order,
decree, ruling or other action shall have become final and nonappealable.

          (e)  ENVIRONMENTAL  REVIEW.   In the event UNIFAB's environmental
due diligence of Allen reveals an environmental condition that would have a
Material Adverse Effect, UNIFAB may terminate  this  Agreement  at any time
prior  to  five  Business Days before the Closing Date by giving notice  to
Allen.

     Section 2.e EFFECT OF TERMINATION.  Upon termination of this Agreement
pursuant to this Article 10, this Agreement shall be void and of no effect,
and shall result in  no  obligation  of  or liability to any party or their
respective directors, officers, employees,  agents  or shareholders, unless
such  termination  was  the  result  of  an  intentional  breach   of   any
representation,  warranty  or  covenant in this Agreement in which case the
party who breached the representation, warranty or covenant shall be liable
to the other party for damages,  and  all  costs  and  expenses incurred in
connection with the preparation, negotiation, execution  and performance of

headings contained in this Agreement  are  for  reference purposes only and
shall  not  affect  in  any  way  the  meaning  or interpretation  of  this

construed as constituting, separate representations  or  warranties  of the
party  to  which such Schedules relate except as and to the extent provided
in this Agreement.   Inclusion of information in the Schedules shall not be
construed as an admission that such information is material for purposes of
the  specific provisions  of  this  Agreement  to  which  such  information
relates.   Information included in the Schedules that is not required to be
