Item 5.  Other Events

       On December 21, 1995 Hornbeck Offshore Services, Inc.
  ("Hornbeck") entered into  a  definitive  merger agreement
  with Tidewater Inc. ("Tidewater") that would  combine  the
  two  companies.   The  merger  will  be accounted for as a
  pooling-of-interests and will be structured  as a tax free
  exchange  of  .667 of a Tidewater share for each  Hornbeck
  share, subject  to  adjustment if the average market price
  of  Tidewater shares (calculated  over  a  ten-day  period
  immediately  prior  to the closing) is less than $24.50 or
  greater  than $32.50.   Either  party  may  terminate  the
  transaction  if  the  average  market  price  of Tidewater
  shares prior to the closing is less than $22.08 or greater
  than $36.13.

       The   merger   is  subject  to  Hornbeck  stockholder
  approval, Hart-Scott-Rodino  clearance  and  certain other
  conditions.   The  necessary filings for Hart-Scott-Rodino
  clearance and the filing  with the Securities and Exchange
  Commission of Tidewater's Registration  Statement covering
  the Tidewater shares to be issued in the  merger  will  be
  made   as   soon  as  practicable.   Hornbeck  anticipates
  submitting the  merger to its stockholders for approval at
  a  special meeting  in  February  1996.   Subject  to  the
  Hornbeck  stockholder approval and the satisfaction of the
  other conditions,  it  is anticipated that the transaction
  will be consummated in the early spring of next year.

  of incorporation  and  by-laws,  as  amended  or  restated
  through  the date of this Agreement and the organizational
  documents  governing  each  member  of  the Hornbeck Group
  listed on Schedule 4.2.  The minute books  of  each member
  of  the  Hornbeck Consolidated Group, and to the Knowledge
  of Hornbeck,  the minute books of each member of the North
  Sea  Group,  contain   reasonably  complete  and  accurate
  records of all corporate  actions  of the equity owners of
  the  various entities and of the boards  of  directors  or
  other  governing  bodies,  including  committees  of  such
  boards or governing bodies.  The stock transfer records of

  registrar  and, to  the  Knowledge  of  Hornbeck,  contain
  complete  and   accurate  records  of  all  issuances  and
  redemptions of stock  by Hornbeck.  Except as set forth on
  Schedule 4.6, neither Hornbeck  nor,  to  the Knowledge of
  Hornbeck,  any  of  its  Affiliates,  is  a party  to  any

  other than this Agreement.

       Section 4.7  SEC  Documents;   Financial  Statements;
  Liabilities.   (a)   Hornbeck   has   filed  all  required
  reports, schedules, forms, statements and  other documents
  with  the  SEC  since  January 1, 1992 (the "Hornbeck  SEC
  Documents").  The Hornbeck  SEC  Documents,  and  any such
  reports,  forms  and documents filed by Hornbeck with  the
  SEC after the date  hereof,  as amended, complied, or will
  comply,  as  to  form in all material  respects  with  the
  requirements of the Securities Act or the Exchange Act, as
  the case may be, and  the rules and regulations of the SEC
  promulgated thereunder  applicable  to  such  Hornbeck SEC
  Documents,   and   none  of  the  Hornbeck  SEC  Documents
  contained  or will contain,  any  untrue  statement  of  a
  material fact or omitted to state a material fact required
  to be stated  therein  or  necessary  in order to make the
  statements  therein,  in light of the circumstances  under
  which  they  were made, not  misleading.   Except  to  the
  extent that information  contained  in  any  Hornbeck  SEC
  Document has been superseded by a later filed Hornbeck SEC
  Document,  none of the Hornbeck SEC Documents contains any
  untrue statement  of a material fact or omits to state any
  material fact required  to  be stated therein or necessary
  in order to make the statements  therein,  in light of the
  circumstances under which they were made, not misleading.

            (b)   The Hornbeck Financial Statements included
  in the Hornbeck SEC Documents have been audited  by  Price
  Waterhouse  LLP,  independent  accountants (in the case of
  the Hornbeck Audited Financial Statements)  in  accordance
  with  generally  accepted  auditing  standards, have  been
  prepared  in  accordance  with  United  States   generally
  accepted   accounting   principles   applied  on  a  basis
  consistent  with  prior  periods, and present  fairly  the
  financial  position of Hornbeck  at  such  dates  and  the
  results of operations  and cash flows for the periods then
  ended,  except,  in  the  case  of  the  Hornbeck  Interim
  Financial  Statements,  as  permitted  by  Rule  10-01  of
  Regulation S-X of the SEC.  The Hornbeck Interim Financial
  Statements  reflect all adjustments  (consisting  only  of
  normal, recurring  adjustments)  that  are necessary for a
  fair  statement  of  the  results for the interim  periods
  presented  therein.   Except  as  set  forth  on  Schedule
  4.7(b), no member of the  Hornbeck Consolidated Group has,
  nor are any of their respective  assets  subject  to,  any
  liability,  commitment,  debt  or  obligation (of any kind
  whatsoever whether absolute or contingent, accrued, fixed,
  known,   unknown,  matured  or  unmatured)   ("Undisclosed
  Liabilities"),  except  (i) as and to the extent reflected
  on the Hornbeck Latest Balance  Sheet, or (ii) as may have
  
<APGE> 12

  been incurred or may have arisen  since  the  date  of the
  Hornbeck  Latest  Balance Sheet in the ordinary course  of
  business and that are  not material individually or in the
  aggregate or are permitted by this Agreement.

            (c)   The Hornbeck Latest Balance Sheet includes
  appropriate reserves for  all  Taxes and other liabilities
  incurred as of such date but not yet payable.

            (d)   Since  the  date of  the  Hornbeck  Latest
  Balance Sheet, there has been no change that has had or is
  likely to have a Material Adverse Effect on Hornbeck.

            (e)   The statements  of  income included in the
  Hornbeck Financial Statements do not contain any income or
  revenue   realized   from  services  that  the   Surviving
  Corporation  would  be  prohibited   or   restricted  from
  offering after the Effective Time pursuant to any covenant
  or provision in any material contract to which  any member
  of the Hornbeck Consolidated Group is a party.

            (f)   Hornbeck's  investment  in  the North  Sea
  Group  is  recorded  on  the Hornbeck Financial Statements
  under the equity method of accounting.  Attached hereto as
  Schedule 4.7(f) is a balance sheet reflecting the combined
  operations of the North Sea Group as of September 30, 1995
  (the  "North Sea Group Latest  Balance  Sheet").   To  the
  Knowledge  of  Hornbeck,  except as reflected on the North
  Sea Group Latest Balance Sheet, no member of the North Sea
  Group has, nor are any of its  respective  assets  subject
  to,  any  indebtedness  for  borrowed money, except as may
  have been incurred or may have  arisen  since  the date of
  the  North Sea Group Latest Balance Sheet in the  ordinary
  course  of  business.   Except  as  set  forth on Schedule
  4.7(f),  there  is  no  liability,  commitment,   debt  or
  obligation  (of  any  kind whatsoever whether absolute  or
  contingent, accrued, fixed,  known,  unknown,  matured  or
  unmatured)  of  the  North  Sea  Group  which is, or could
  reasonably be expected to become, a liability, commitment,
  debt  or  other  obligation  of the Hornbeck  Consolidated
  Group.

       Section 4.8  Accounts Receivable. All of the accounts
  receivable reflected on the Hornbeck Latest  Balance Sheet
  or  created  thereafter  have  arisen only from bona  fide
  transactions in the ordinary course of business, represent
  valid obligations owing to Hornbeck  or  another member of
  the Hornbeck Consolidated Group and have been  accrued and
  recorded   in  accordance  with  United  States  generally
  accepted accounting  principles.   Except  as set forth on
  Schedule  4.8, such accounts receivable either  have  been
  collected in full or will be collectible in full when due,
  without any  counterclaims, set-offs or other defenses and
  without provision  for  any  allowance  for  uncollectible
  accounts  other  than  such  allowance as appears  on  the
  Hornbeck Latest Balance Sheet.

  of the Hornbeck  Consolidated  Group, or, to the Knowledge
  of  Hornbeck,  any  member  of the North  Sea  Group,  has
  breached any of the terms or  conditions  of  any  of  its
  material  agreements, contracts or commitments, and to the
  Knowledge  of   Hornbeck,   no   other   parties  to  such
  agreements, contracts or commitments have  breached any of
  its terms or conditions.  Tidewater has been provided with

  in the conduct of its business,  good  and  valid title to

  is properly reflected in the Hornbeck Latest Balance Sheet
  or the North  Sea  Group  Latest Balance Sheet; (ii) Liens

  obligations collateralized by any such contested Permitted
  Liens  in  the  aggregate  exceed   $150,000;   (iv)  such

  (v) capital leases and leases of such  properties, if any,
  to  third  parties  for  fair  and adequate consideration.

  Consolidated Group and, to the Knowledge  of  Hornbeck,  a
  member  of  the  North  Sea  Group,  owns,  or  has  valid
  leasehold  interests  in, all properties and assets, other

            (b)   With respect  to  each  lease  of any real
  property, or a material amount of other personal  property
  (other  than  vessels)  to  which a member of the Hornbeck

  thereto; (v) there exists no material default (or an event
  that,   with  notice  or  lapse  of  time  or  both  would
  constitute a material default) under such lease; (vi) such
  member of the Hornbeck Consolidated Group has not violated
  any of the terms or conditions under any such lease and to
  the Knowledge of Hornbeck there has been no, (A) condition
  or covenant to be observed or performed by any other party
  under any  such lease that has not been fully observed and
  performed  and  (B)  in  the  case  of  each  prime  lease
  concerning demised premises subleased to any member of the
  Hornbeck Consolidated  Group,  condition or covenant to be

  become a default under any such prime lease; and (vii) the
  transactions   described  in  this  Agreement   will   not

  Hornbeck Group under any lease, other than with respect to
  vessels, between any member of the Hornbeck  Group and any
  of  its  Affiliates  (other  than  another  member of  the
  Hornbeck  Group)  is at or below the market rate  and  any
  such lease  contains  such other terms and conditions that
  are no less favorable to Hornbeck than would be obtainable
  in an arms-length transaction  with  an  independent third
  party lessor.

            (d)   Schedule 4.11(d) contains  a  list  of all
  real property owned by members of the Hornbeck Group and a
  list of all leases, other than with respect to vessels, to
  which the members of the Hornbeck Group are parties, which
  list includes a reasonable description of the location and
  approximate square footage of each property, whether owned
  or leased, and the term of each such lease, including  all
  renewal  options.   Complete  and  correct  copies of each
  lease have been delivered to Tidewater.

       Section 4.12  Condition  of  Hornbeck's  Assets Other 
  than Vessels.  All of the tangible assets  of the Hornbeck
  Consolidated Group (other than vessels) are  currently  in
  good   and   usable  condition,  ordinary  wear  and  tear
  excepted, and  are  being  used  in  the  business  of the
  Hornbeck Consolidated Group.  There are no defects in such
  assets   or   other  conditions  that  have  or  would  be
  reasonably likely  to  have,  a Material Adverse Effect on
  Hornbeck.   Such  assets and the  other  properties  being
  leased by a member  of  the Hornbeck Group pursuant to the
  leases described on Schedule  4.11(d),  together  with the
  vessels  listed  on  Schedule 4.13, constitute all of  the
  operating assets being  utilized  by the Hornbeck Group in
  the conduct of its business and such assets are sufficient
  in quantity and otherwise adequate  for  the operations of
  the Hornbeck Group as currently conducted.

       Section 4.13  Vessels.   (a) Schedule 4.13(a)  hereto
  sets forth a list of all vessels owned,  leased, chartered

  hereof  and the name of the nation under which  each  such
  vessel is  documented  and flagged, and indicates any such
  vessels that are laid up  or  being  held  for sale on the
  date  hereof  (such  vessels (other than any such  vessels
  that are managed on the  date  hereof)  being  referred to
  herein as "Hornbeck Vessels").  With respect to  the owned
  Hornbeck Vessels, a member of the Hornbeck Group has  good
  title  to  each  such  vessel free and clear of all Liens,
  except for (i) Liens that  collateralize indebtedness that
  is properly reflected in the Hornbeck Latest Balance Sheet
  or the North Sea Group Latest  Balance  Sheet;  (ii) Liens
  
<PAGE> 17

  for  Taxes  accrued  but  not yet payable; (iii) Permitted
  Liens provided that the obligations collateralized by such
  Permitted Liens are not delinquent  or are being contested
  in  good  faith  and  in  no event shall the  obligations,
  individually or in the aggregate,  collateralized  by such
  contested   Permitted   Liens   exceed   $150,000  in  the
  aggregate.  Schedule 4.13(a) contains a list  of all Liens
  (other  than  Permitted  Liens) on vessels collateralizing
  indebtedness on the Hornbeck  Latest  Balance Sheet or the
  North Sea Group Latest Balance Sheet and  any  guaranty or
  other  credit  support  arrangement pursuant to which  any
  member of the Hornbeck Group  has guaranteed an obligation
  of any other member of the Hornbeck  Group  where  vessels
  are the collateral.

       (b)  With  respect  to  each Hornbeck Vessel that  is
  operated by a member of the Hornbeck  Group under lease or
  charter, (i) such member of the Hornbeck Group has a valid
  right  to  charter or a valid leasehold interest  in  such
  vessel; (ii)  such  charter  agreement or lease is in full
  force and effect in accordance  with  its terms; (iii) all
  rents,  charter payments and other monetary  amounts  that
  have become  due  and payable thereunder have been paid in
  full; (iv) no waiver,  indulgence  or  postponement of the
  obligations thereunder has been granted by the other party
  thereto; (v) there exists no material default (or an event
  that,  with  notice  or  lapse  of  time  or  both   would
  constitute   a   material   default)  under  such  charter
  agreement or lease; (vi) such member of the Hornbeck Group
  has not violated any of the terms  or conditions under any
  such charter agreement or lease and  to  the  Knowledge of
  Hornbeck there is no condition or covenants to be observed
  or  performed  by  any  other  party  under  such  charter
  agreement  or  lease  that has not been fully observed  or
  performed; and (viii) the  transactions  described in this
  Agreement will not constitute a default under or cause for
  termination or modification of such charter  agreement  or
  lease.

       (c)  Schedule  4.13(c)  contains a list of all leases
  or charters providing for the  use  by  a  member  of  the
  Hornbeck  Group  of a Hornbeck Vessel other than leases or
  charters between members  of  the  North  Sea Group, which
  list contains a description of the terms of  such lease or
  charter.   Complete  and correct copies of each  lease  or
  charter have been delivered to Tidewater.

       (d)  With respect  to each Hornbeck Vessel:  (i) such
  Hornbeck Vessel is lawfully  documented  under the flag of
  the  nation  listed  on  Schedule  4.13 for such  Hornbeck
  Vessel,  (ii)  such  Hornbeck  Vessel  is  afloat  and  in
  satisfactory operating condition for charter  hire,  (iii)
  such  Hornbeck  Vessel  holds in full force and effect all
  certificates, licenses, permits  and  rights  required for
  operation  in  the  manner  vessels of its kind are  being
  operated in the geographical  area  in which such Hornbeck
  Vessel is presently being operated and  (iv)  no event has
  occurred  and no condition exists that would endanger  the
  maintenance of the classification of such Hornbeck Vessel.

       Section 4.14  Voting  Requirements.  The  affirmative
  vote  of  the  holders  of  not less than 66-2/3%  of  the
  outstanding shares of Hornbeck  Common  Stock  entitled to
  vote on the Merger is the only vote of the holders  of any
  class  or series of Hornbeck's capital stock necessary  to
  approve  this  Agreement  and  the  transactions described
  herein.

       Section  4.15  State   Takeover  Statutes;   Hornbeck
  Stockholder Rights Plan.  (a)  The Board  of  Directors of
  Hornbeck has approved the Merger, this Agreement  and  the
  transactions   described   in   this  Agreement,  and  the
  provisions of Section 203 of the  DGCL are inapplicable to
  
<PAGE> 18

  the Merger, this Agreement and the  transactions described
  in this Agreement; provided, however,  that  the foregoing
  shall not be construed to mean that the Board of Directors
  of  Hornbeck  has  approved  any  stockholder  of Hornbeck
  becoming  an  "Interested  Stockholder"  for  purposes  of
  Section 203 of the DGCL.  No other state takeover  statute
  or  similar  statute or regulation applies or purports  to
  apply to Hornbeck  in  connection  with  the  Merger, this
  Agreement  or  any of the transactions described  in  this
  Agreement.

       (b)  The Board of Directors of Hornbeck has taken all
  action necessary  to render the provisions of the Hornbeck
  Stockholder Rights  Plan  inapplicable  to  Tidewater, the
  Merger,  this Agreement and the transactions described  in
  this Agreement.

       Section 4.16  Accounting  Matters.  No  member of the
  Hornbeck  Group, nor to the Knowledge of Hornbeck  any  of
  its Affiliates,  has  taken  or  agreed to take any action
  that (without giving effect to any  action taken or agreed
  to be taken by Tidewater or any of its  Affiliates)  would
  prevent   Tidewater   from  accounting  for  the  business
  combination to be effected  by the Merger as a pooling-of-
  interests.  Within three business days of the execution of
  this Agreement, Hornbeck will  have  received letters from
  its  independent  public  accountants  and  the  Tidewater
  independent public accountants to the effects  that if the
  Merger  were  to  be  consummated  on  the  date  of  this
  Agreement,   it  would  qualify  for  pooling-of-interests
  treatment  under   the   generally   accepted   accounting
  principles of the United States.

       Section  4.17  Suppliers   and  Customers.    To  the
  Knowledge of Hornbeck, (a) no supplier providing products,
  materials or services to any member of the Hornbeck  Group
  intends  to  cease  selling  such  products,  materials or
  services to any member of the Hornbeck Group or  to  limit
  or  reduce  such sales to any member of the Hornbeck Group
  or materially  alter  the  terms or conditions of any such
  sales and (b) no customer of  any  member  of the Hornbeck
  Group intends to terminate, limit or reduce  its  or their
  business relations with any member of the Hornbeck Group.

       Section 4.18  Employee Matters.  (a) Schedule 4.18(a)
  sets forth the  name,  title,  current annual compensation
  rate  (including  bonus  and  commissions),  current  base
  salary rate, accrued bonus, accrued  sick  leave,  accrued
  severance  pay  and  accrued  vacation  benefits  of  each
  officer of each member of the Hornbeck Consolidated Group,
  and   a  list  of  all  employment,  consulting,  employee
  confidentiality  or similar agreements to which any member
  of the Hornbeck Consolidated  Group is a party.  Copies of
  organizational charts, any employee  handbook(s),  and any
  reports  and/or plans prepared or adopted pursuant to  the
  Equal Employment Opportunity Act of 1972, as amended, have
  been provided to Tidewater.

            (b)   Each of the following is true with respect
  to the Hornbeck  Consolidated  Group and, to the Knowledge
  of Hornbeck, the North Sea Group:

                  (i) each such member is in compliance with
  all applicable laws respecting employment  and  employment
  practices,  terms and conditions of employment, wages  and
  hours and occupational  safety  and  health,  and  is  not
  engaged in any unfair labor practice within the meaning of
  Section 8  of  the National Labor Relations Act, and there
  is  no  proceeding   pending   or   threatened,   or,  any
  investigation pending or threatened against it relating to
  
  <PAGE> 19

  any thereof, and to the Knowledge of Hornbeck there  is no
  basis for any such proceeding or investigation;

                  (ii)none  of  the  employees  of  any such
  member is a member of, or represented by, any labor  union
  and  there  are  no  efforts being made to unionize any of
  such employees; and

                  (iii)there  are  no  charges  of,  formal,
  informal   or   internal  complaints  of,  or  proceedings
  involving, discrimination or harassment (including but not
  limited to discrimination  or  harassment  based upon sex,
  age,   marital  status,  race,  religion,  color,   creed,
  national  origin,  sexual  preference, handicap or veteran
  status)  pending  or  threatened,   nor   is   there   any
  investigation  pending  or  threatened, including, but not
  limited  to, investigations before  the  Equal  Employment
  Opportunity  Commission  or  any  federal,  state or local
  agency or court, with respect to any such member.

       Section 4.19  Employee Benefit Plans. With respect to
  any member of the Hornbeck Consolidated Group:

            (a)   Schedule 4.19(a) lists each Employee  Plan
  that  each  member  of  the  Hornbeck  Consolidated  Group
  maintains,   administers,   contributes  to,  or  has  any
  contingent liability with respect  thereto.   Hornbeck has
  provided  a  true and complete copy of each such  Employee
  Plan,  current   summary   plan   description,   (and,  if
  applicable,  related  trust  documents) and all amendments
  thereto and written interpretations  thereof together with
  (i) the  three  most  recent  annual reports  prepared  in
  connection  with  each  such  Employee   Plan  (Form  5500
  including,  if  applicable, Schedule B thereto);  (ii) the
  most recent actuarial  report,  if  any, and trust reports
  prepared in connection with each Employee  Plan; (iii) all
  material  communications  received  from  or sent  to  the
  Internal  Revenue  Service  ("IRS")  or the Department  of
  Labor  within  the  last  two years (including  a  written
  description of any material oral communications); (iv) the
  most recent IRS determination  letter with respect to each
  Employee  Plan  and  the  most recent  application  for  a
  determination letter; (v) all insurance contracts or other
  funding arrangements; and (vi)  an  actuarial study of any
  post-employment life or medical benefits provided, if any.

            (b)   Schedule 4.19(b) identifies  each  Benefit
  Arrangement  that each member of the Hornbeck Consolidated
  Group maintains,  administers,  contributes to, or has any
  contingent liability with respect  thereto.   Hornbeck has
  furnished  to  Tidewater  copies  or descriptions of  each
  Benefit Arrangement and any of the  information  set forth
  in   Section   4.19(a)  applicable  to  any  such  Benefit
  Arrangement.  Each Benefit Arrangement has been maintained
  and administered  in substantial compliance with its terms
  and   with   the   requirements    (including    reporting
  requirements) prescribed by any and all statutes,  orders,
  rules and regulations which are applicable to such Benefit
  Arrangement.

            (c)   Benefits   under   any  Employee  Plan  or
  Benefit Arrangement are as represented  in  said documents
  and  have not been increased or modified (whether  written
  or not written) subsequent to the dates of such documents.
  No  member   of   the   Hornbeck  Consolidated  Group  has
  communicated  to  any  employee  or  former  employee  any
  intention or commitment  to  modify  any  Employee Plan or
  Benefit Arrangement or to establish or implement any other
  employee or retiree benefit or compensation arrangement.

  <PAGE> 20

            (d)   No  Employee  Plan  is (i) a Multiemployer
  Plan,  (ii) a  Title  IV  Plan or (iii) is  maintained  in
  connection with any trust described  in  Section 501(c)(9)
  of the Code.  No member of the Hornbeck Consolidated Group
  has ever maintained or become obligated to  contribute  to
  any  employee benefit plan (i) that is subject to Title IV
  of ERISA,  (ii) to  which Section 412 of the Code applies,
  or (iii) that is a Multiemployer  Plan.   No member of the
  Hornbeck Consolidated Group has within the last five years
  engaged  in,  or is a successor corporation to  an  entity
  that has engaged  in,  a  transaction described in Section
  4069 of ERISA.

            (e)   Each Employee Plan which is intended to be
  qualified under Section 401(a) of the Code is so qualified
  and  has  been so qualified during  the  period  from  its
  adoption to  date,  and  no  event has occurred since such
  adoption that would adversely  affect  such  qualification
  and  each  trust  created  in  connection  with each  such
  Employee  Plan forming a part thereof is exempt  from  tax
  pursuant to  Section  501(a)  of  the  Code.   A favorable
  determination letter has been issued by the IRS  as to the
  qualification  of  each such Employee Plan under the  Code
  and to the effect that  each  such  trust  is  exempt from
  taxation under Section 501(a) of the Code.  Each  Employee
  Plan  has  been  maintained and administered in compliance
  with  its  terms  and  with  the  requirements  (including
  reporting  requirements)   prescribed   by   any  and  all
  applicable   statutes,   orders,  rules  and  regulations,
  including but not limited to ERISA and the Code.

            (f)   Full payment  has been made of all amounts
  which any member of the Hornbeck  Consolidated Group is or
  has  been  required  to have paid as contributions  to  or
  benefits  due  under  any   Employee   Plan   or   Benefit
  Arrangement under applicable law or under the terms of any
  such plan or any arrangement.

            (g)   No  member  of  the  Hornbeck Consolidated
  Group, or any of their respective directors,  officers  or
  employees  has  engaged in any transaction with respect to
  an Employee Plan  that  could  subject  Hornbeck to a tax,
  penalty  or  liability  for  a prohibited transaction,  as
  defined in Section 406 of ERISA  or  Section  4975  of the
  Code.   None  of  the  assets  of  any  Employee  Plan are
  invested in employer securities or employer real property.

            (h)   To the Knowledge of Hornbeck, there are no
  facts  or  circumstances  that  might  give  rise  to  any
  liability under Title I of ERISA.

            (i)   No  member  of  the  Hornbeck Consolidated
  Group has any current or projected liability in respect of
  post-retirement  or post-employment welfare  benefits  for
  retired, current or  former  employees, except as required
  to avoid excise tax under Section 4980B of the Code.

            (j)   Except as disclosed  on  Schedule 4.19(j),
  there  is  no  litigation,  administrative or  arbitration
  proceeding  or other dispute pending  or  threatened  that
  involves any  Employee  Plan  or Benefit Arrangement which
  could reasonably be expected to  result  in a liability to
  the Hornbeck Consolidated Group or Tidewater.

            (k)   No  employee  or  former employee  of  any
  member  of  the Hornbeck Consolidated  Group  will  become
  entitled to any bonus, retirement, severance, job security
  or  similar  benefit   or   enhanced   benefit  (including
  acceleration  of  an  award,  vesting  or exercise  of  an
  incentive award) or any fee or payment of  any kind solely
  as  a  result  of  any  of  the  transactions contemplated
  
<PAGE> 21

  hereby,  except as disclosed on Schedule  4.19(k)  and  no
  such disclosed  payment  constitutes  a  parachute payment
  described in Section 280G of the Code, except as disclosed
  on Schedule 4.19(k).

            (l)   To  the Knowledge of Hornbeck,  all  group
  health plans (as defined  in  Code  Section 5000(b)(1)) of
  any member of the Hornbeck Consolidated  Group have at all
  times fully complied with all applicable notification  and
  continuation  coverage requirements of Section 4980B(f) of
  the Code and Section  601  of  ERISA,  and the regulations
  promulgated   thereunder.    Further,  no  Employee   Plan
  provides health, medical, death  or  survivor  benefits to
  any  stockholders  or  directors  who  are  not employees,
  former employees or beneficiaries thereof, except  to  the
  extent otherwise required by the continuation requirements
  of Section 4980B(f) of the Code and Section 601 of ERISA.

            (m)   No employee or former employee, officer or
  director  of any member of the Hornbeck Consolidated Group
  is or will  become  entitled  to  receive  any award under
  Hornbeck's discretionary or other bonus plans  except  for
  (i)  cash  payments  pursuant  to  Section 6.4(j) of up to
  $350,000 in 1995 Incentive Cash Payments  (as  defined  in
  Section  6.4(j)),  (ii)  the  issuance pursuant to Section
  6.4(j)  of  an aggregate of 19,310  shares  of  restricted
  Hornbeck Common  Stock  for  1995 performance and (iii) if
  the Closing Date has not occurred  by April 30, 1996, cash
  payments to officers and employees as  incentive  payments
  for  1996 performance for the period from January 1,  1996
  through  the Closing Date, such amounts to be prorated and
  based on the  total  1995  Incentive  Cash Payments and to
  otherwise be consistent with past practice.

  provision of state, local or foreign tax law);

                  (ii)except   as   set  forth  on  Schedule
  4.20(a)(ii), each member of the Hornbeck  Group  has  paid
  all  Taxes required to be paid by it (whether or not shown
  on a Return)  or  for  which it could be liable, (provided
  that  it  shall  not  be  considered   a  breach  of  this
  representation   if  it  is  ultimately  determined   that
  additional tax payments  are  due  but  such assessment is
  based  on an adjustment to a return or position,  if  such
  member has  a reasonable basis for the position taken with
  respect to such  Taxes),  whether to taxing authorities or
  to  other  persons  under  tax  allocation  agreements  or
  otherwise, and the charges,  accruals,  and  reserves  for
  Taxes  due,  or  accrued  but not yet due, relating to its
  income, properties, transactions  or  operations  for  any
  Pre-Closing  Period  as reflected on its books (including,
  without limitation, the  Hornbeck  Latest Balance Sheet or

                  (iii)there are no agreements  or  consents
  currently  in  effect  for the extension or waiver of  the

  Pre-Closing Period,  and  no member the Hornbeck Group has
  been  requested  to  enter  into  any  such  agreement  or
  consent;

                  (iv)there are  no  Liens  for Taxes (other
  than for current Taxes not yet due and payable)  upon  the
  assets of any member of the Hornbeck Group;

                  (v) all material elections with respect to
  Taxes  affecting  any  member of the Hornbeck Consolidated
  Group are set forth in Schedule 4.20(a)(v);

                  (vi)all  Taxes  that the Hornbeck Group is
  required  by  law to withhold or collect  have  been  duly
  withheld or collected,  and  have been timely paid over to
  the appropriate governmental authorities to the extent due
  and payable (provided that it  shall  not  be considered a
  breach   of   this  representation  if  it  is  ultimately
  determined that  additional  tax payments are due but such
  assessment  is  based  on an adjustment  to  a  return  or
  position, if such member  has  a  reasonable basis for the
  position  taken  with  respect  to  such  withholding  and
  collection);

                  (vii)Schedule  4.20(a)(vii)   hereto  sets
  forth (A) the taxable years of each member of the Hornbeck
  Group  as  to which the respective statutes of limitations
  with respect  to  Taxes  have  not  expired,  and (B) with
  respect  to  such  taxable  years,  those years for  which
  examinations  have  not been completed,  those  years  for
  which examinations are  currently  being  conducted, those
  years for which examinations have not been  initiated, and
  those years for which required Returns have not  yet  been
  filed.  Schedule 4.20(a)(vii) lists each state and foreign
  jurisdiction  in  which  any  member of the Hornbeck Group
  has, in the last three years, filed a Return.

                  (viii)all Tax Deficiencies which have been
  claimed, proposed or asserted against  any  member  of the
  Hornbeck  Group  have  been fully paid or finally settled,
  and no issue has been raised  in any examination which, by
  application  of similar principles,  can  be  expected  to
  result in the  proposal  or  assertion of a Tax Deficiency
  for any other year not so examined;

                  (ix)to  the Knowledge  of  Hornbeck,  each
  member of the Hornbeck Group  has complied in all material
  respects with all applicable Tax laws;

                  (x) except  as  set   forth   on  Schedule
  4.20(a)(x), no member of the Hornbeck Group is  a party to
  any  agreement,  contract, arrangement or plan that  would
  result, separately  or in the aggregate, in the payment of
  any "excess parachute payments" within the meaning of Code
  Section 280G (or any  comparable  provision  of  state  or
  local law);

  allegation against  any member of the Hornbeck Group for a

  the disclosure in the first paragraph of Schedule 4.23(b).

  interest  payments  and penalties due and payable (for all
  periods up to the Effective  Date,  including that portion
  of its fiscal year to and including the Effective Date) to
  any city, parish, state, the United States, foreign or any
  other taxing authority, except those  being  contested  in
  good  faith  by  appropriate  proceedings  and  for  which
  sufficient  reserves  have  been  established, or make any
  elections with respect to Taxes;

            (h)   make  any material tax  election  that  is
  inconsistent with any corresponding  election  made  on  a
  prior  return  or  settle  or  compromise  any  income tax
  liability  for  an  amount  materially  in  excess  of the
  liability  therefor  that  is  reflected  on  the Hornbeck
  Financial Statements or Tidewater Financial Statements, as
  the case may be;

            (i)   take  any  action  that would prevent  the
  accounting for the business combination  to be effected by

  any of, the foregoing actions.

  the Closing Date.  During the period from the date of this

  to  January  2,  1996,  and  provided further that, if the
  Closing Date has not occurred  by  April  30,  1996,  cash
  payments   may  be  made  to  officers  and  employees  as
  incentive payments  for  1996  performance  for the period
  from  January  1,  1996  through  the  Closing Date,  such
  amounts  to  be  prorated  and  based  on the  total  1995
  Incentive  Cash  Payments and to otherwise  be  consistent
  with past practice; or

            (k)   authorize any of, or agree or commit to do
  any of, the foregoing actions.

  In addition, Hornbeck  shall  consult  with Tidewater with
  respect to any action of the type described above proposed
  to be taken by a member of the North Sea Group.

       Section 6.5  No Solicitations.  (a) No  member of the
  Hornbeck  Group shall directly or indirectly, through  any
  officer, director,  employee,  representative  or agent of
  any member of the Hornbeck Group, solicit or encourage the
  initiation  or  submission of any inquiries, proposals  or
  offers regarding  any  acquisition, merger, take-over bid,
  sale of all or substantially  all  of  the  assets  of, or
  sales  of shares of capital stock of Hornbeck, whether  or
  not  in writing  and  whether  or  not  delivered  to  the
  stockholders  of  Hornbeck  generally  (including  without
  limitation   by   way  of  a  tender  offer),  or  similar
  transactions involving  Hornbeck  (any  of  the  foregoing
  inquiries  or  proposals  being  referred to herein as  an
  "Acquisition Proposal"); provided,  however,  that nothing
  contained  in  this  Agreement shall prevent the Board  of
  Directors of Hornbeck  from  referring  any third party to
  this Section 6.5.  Nothing contained in this  Section  6.5
  or any other provision of this Agreement shall prevent the
  Board   of  Directors  of  Hornbeck  from  considering  or
  negotiating  an  unsolicited bona fide written Acquisition
  Proposal.  If the  Board  of  Directors of Hornbeck, after
  duly considering advice, written  or otherwise, of outside
  counsel and financial advisors to Hornbeck,  determines in
  good faith that it would be consistent with its  fiduciary
  responsibilities   to   approve   or   recommend  (and  in
  connection therewith withdraw or modify  its  approval  or
  recommendation  of  this  Agreement,  and the transactions
  contemplated  hereby or thereby) a Superior  Proposal  (as
  defined below), then, notwithstanding any such approval or
  recommendation  (x)  Hornbeck  shall  not  enter  into any
  agreement  with  respect to the Superior Proposal and  (y)
  any other obligation  of  Hornbeck  under  this  Agreement
  shall not be affected, unless this Agreement is terminated
  pursuant   to   Section   9.1(f)   hereof   prior   to  or
  
<PAGE> 39

  simultaneously  with  the  grant  of  such approval or the
  making of such recommendation and Hornbeck,  within  three
  Business  Days  following  such termination resulting from
  such Superior Proposal, pays Tidewater the Termination Fee
  (as defined in Section 9.1(f)).   As  used herein the term
  "Superior Proposal" means a bona fide proposal  made  by a
  third  party  to  acquire Hornbeck pursuant to a tender or
  exchange offer, a merger,  a  sale of all or substantially
  all of its assets or otherwise that the Board of Directors
  determines in its good faith judgment to be more favorable
  to   Hornbeck's   stockholders   than   the   transactions
  contemplated  by  this  Agreement (after  considering  the
  advice, written or otherwise,  of  Hornbeck's professional
  advisors).   In  making  a  determination   of  whether  a
  Superior Proposal is more favorable, the Hornbeck Board of
  Directors shall consider not only the price offered by the
  third  party  as  compared to the total consideration  set
  forth in this Agreement, but shall also compare the market
  liquidity of the Tidewater  Common  Stock to the liquidity
  of the consideration offered by the third  party,  compare
  the tax consequences of the Merger to the tax consequences
  of  the transaction proposed by the third party, determine
  whether  the  transaction  proposed by the third party has
  any financing or other conditions  or  contingencies,  and
  make  any  other  meaningful  comparison  of  the relative
  benefits  offered  to  the  Hornbeck  stockholders by  the
  Merger  as  compared  to the transaction proposed  by  the
  third party.

            (b)   Hornbeck    shall    immediately    notify
  Tidewater after receipt of any Acquisition Proposal or any
  request  for  nonpublic information relating to any member
  of the Hornbeck  Group  in  connection with an Acquisition
  Proposal or for access to the properties, books or records
  of any member of the Hornbeck Group that informs the Board
  of Directors of any member of  the  Hornbeck Group that it
  is  considering  making,  or  has  made,  an   Acquisition
  Proposal.  To the extent not prohibited by confidentiality
  provisions  imposed by the offering party, such notice  to
  Tidewater shall  be  made  orally and in writing and shall
  indicate in reasonable detail  the identity of the offeror
  and the terms and conditions of  such proposal, inquiry or
  contact.

            (c)   If  the  Board  of Directors  of  Hornbeck
  receives a request for material nonpublic information by a
  Person  who  makes,  or  who  states in  writing  that  it
  intends, subject to satisfactory  review of such nonpublic
  information,  to  make, a bona fide Acquisition  Proposal,
  Hornbeck   may,   subject    to   the   execution   of   a
  confidentiality agreement substantially  similar  to  that
  then  in  effect  between  Hornbeck and Tidewater, provide
  such Person with access to information regarding Hornbeck.

            (d)   Nothing  contained  in  this  Section  6.5
  shall prevent Hornbeck from  complying  with Rule 14e-2(a)
  or  Rule  14d-9  promulgated  under the Exchange  Act,  if
  applicable, with regard to an Acquisition Proposal made in
  the form of a tender offer by a third party.

       Section 6.6  Press Releases.  Hornbeck and  Tidewater
  will  consult  with each other before issuing, and provide
  each other the opportunity to review and comment upon, any
  press releases or  other public statements with respect to
  any transactions described  in  this  Agreement, including
  the Merger, and shall not issue any such press releases or
  make any such public statement prior to such consultation,
  except as may be required by applicable law, court process
  or by obligations pursuant to a listing agreement with the
  Nasdaq National Market or the New York Stock Exchange.

       Section 6.7 Access to Information and Confidentiality.
  (a)   Prior  to  the  Closing Date, each of  Hornbeck  and
  Tidewater shall afford  to  the  other  party  and  to the
  officers,   employees,   accountants,  counsel,  financial
  advisors and other representatives  of  such  other party,
  reasonable  access during normal business hours  to  their
  respective premises, books and records and will furnish to
  the other party  (i)  a  copy  of  each  report, schedule,
  registration  statement and other documents  filed  by  it
  during such period pursuant to the requirements of federal
  or state securities  laws, and (ii) such other information
  with respect to its business  and properties as such other
  party reasonably requests.

            (b)   Each of Hornbeck  and  Tidewater will, and
  will cause its officers, directors, employees,  agents and
  representatives   to,   (i)  hold  in  confidence,  unless
  compelled  to  disclose  by   judicial  or  administrative
  process,  or,  in the opinion of  its  counsel,  by  other
  requirements of  law, all nonpublic information concerning
  the  other  party  furnished   in   connection   with  the
  transactions  contemplated  by  this Agreement until  such
  time  as  such  information  becomes   publicly  available
  (otherwise than through the wrongful act  of such person),
  (ii) not release or disclose such information to any other
  person,  except in connection with this Agreement  to  its
  auditors, attorneys, financial advisors, other consultants
  and advisors,  and  (iii) not use such information for any
  competitive or other  purpose  other  than with respect to
  its  consideration  and  evaluation  of  the  transactions
  contemplated   by   this  Agreement.   In  the  event   of
  termination of this Agreement for any reason, Hornbeck and
  Tidewater will promptly  return  or  destroy all documents
  containing  nonpublic  information  so obtained  from  the
  other party and any copies made of such  documents and any
  summaries, analyses or compilations made therefrom.

       Section 6.8  Consultation and Reporting.   During the
  period from the  date  of  this  Agreement  to the Closing
  Date, each of Hornbeck and Tidewater will, subject  to any
  applicable  legal or contractual restrictions confer on  a
  regular  and frequent  basis  with  the  other  to  report
  material operational  matters and to report on the general
  status  of  ongoing  operations.   Each  of  Hornbeck  and
  Tidewater  will  notify   the   other  of  any  unexpected
  emergency  or other change in the  normal  course  of  its
  business or  in the operation of its properties and of any
  governmental  complaints,   investigations,   adjudicatory
  proceedings,  or  hearings  (or  communications indicating
  that the same may be contemplated) and will keep the other
  fully   informed   of   such   events   and   permit   its
  representatives prompt access to all materials prepared by
  or  on  behalf  of  such  party  or  served  on  them,  in
  connection therewith.

       Section 6.9  Update Schedules. Each party hereto will
  promptly  disclose  to the other any information contained
  in its representations  and  warranties and on the related
  schedules that, because of an  event  occurring  after the
  date hereof, is incomplete or no longer correct; provided,
  however,  that none of such disclosures will be deemed  to
  modify,  amend   or  supplement  the  representations  and
  warranties of such  party, unless the other party consents
  to such modification, amendment or supplement in writing.

       Section 6.10  Hornbeck Stock  Options.   The  parties
  acknowledge and  agree  that,  pursuant to Article XIII of
  the Hornbeck 1989 Employee Incentive Plan and Article XIII
  of the Hornbeck 1993 Employee Incentive  Plan,  any of the
  Hornbeck  Disclosed  Employee  Stock Options issued  under
  such plans that remain unexercised  as of the Closing Date
  shall, in accordance with their terms,  become  options to
  acquire  such  number of shares of Tidewater Common  Stock
  that the holder  of  such  unexercised  Hornbeck Disclosed
  
<PAGE> 41

  Employee Stock Options would have been entitled to receive
  upon  consummation  of  the  Merger  if  such  holder  had
  exercised  such option immediately prior to, or coincident
  with,  the  Merger.    Tidewater   agrees   to  honor  the
  obligations of Hornbeck under such plans effective  as  of
  the Effective Time.

       Section  6.11  Exercise of North  Sea  Options.   The
  parties  agree and acknowledge that Hornbeck, as an equity
  owner of Ravensworth,  Seaboard  and  HOL, owns options to
  acquire   additional  equity  interests  in   Ravensworth,
  Seaboard and  HOL  that  expire  on  various  dates.   The
  parties  agree that Hornbeck shall not exercise, modify or
  cancel such  options  without the prior written consent of
  Tidewater, provided that Hornbeck shall have the right, on
  or after February 29, 1996,  to exercise, modify or cancel
  either or both of the Ravensworth Options after consulting
  with Tidewater, and provided further  that  from  February
  29,  1996 until the Closing Date, Hornbeck will not  issue
  Hornbeck Common Stock as consideration for the exercise of
  such options  without  Tidewater's  prior written consent.
  In the event the Ravensworth Option that  expires on March
  31, 1996 is not exercised by such date, thereby triggering
  mutual rights on behalf of Hornbeck and the 50.1% owner of
  Ravensworth to initiate a sale of Ravensworth, the parties
  agree that Hornbeck will not initiate such  a sale without
  the consent of Tidewater, or take any act with  respect to
  an offer for Ravensworth upon the initiation of a  sale by
  the  other  owner  of  Ravensworth without consulting with
  Tidewater;  provided  that  the  failure  by  Hornbeck  to
  exercise  such  Ravensworth   Option  will  not  alone  be
  construed to be an initiation by Hornbeck of such a sale.

       Section 6.12  Hornbeck 1995 Form 10-K.  (a)  Hornbeck
  agrees to use its best efforts to prepare  and  file  with
  the SEC its annual report on Form 10-K for the fiscal year
  ending December 31, 1995 before the Closing Date.

            (b)   Tidewater  agrees  to  cooperate  in  such
  filing of Hornbeck's Annual Report on Form 10-K.

       Section  6.13  Severance  Policy.  Hornbeck agrees to
  comply  with, and Tidewater agrees to honor, the terms  of
  the severance  policy  for  Hornbeck's  employees that was
  adopted by Hornbeck's Board of Directors  on  December 14,
  1995,  substantially  in  the  form  set forth on Schedule
  6.13.

       Section 6.14  Sub Stockholder Approval. Tidewater, as
  the  sole  stockholder  of  Sub,  shall  take  all  action
  necessary to effect the necessary stockholder approval  by
  Sub of this Agreement.

       Section  6.15  Employee  Indemnification.    Hornbeck
  shall,  at  its  next  Board  of Directors meeting but not
  later than January 31, 1996, amend that certain resolution
  adopted by the Hornbeck Board of Directors on November 19,
  1995 to limit its application to  the  matter disclosed in
  the first paragraph of Schedule 4.23(b).

       Section 6.16  Change in Control Agreements.  Hornbeck
  agrees that the  four  officers  of  Hornbeck  entitled to
  payments  under those certain Change in Control Agreements
  entered into  on  June  20, 1995, shall not be entitled to
  payments under Section 9(b)(iii)  of  such  agreements  in
  excess  of the amounts listed opposite each such officer's
  name on Schedule  6.16 provided however that the foregoing
  does not limit in any  way  the  obligations  of  Hornbeck
  
<PAGE> 42

  pursuant  to the other provisions of the Change in Control
  Agreements.    Tidewater   agrees   to   cause   Surviving
  Corporation  to  honor such agreements in accordance  with
  their terms.

  ARTICLE 8.  POST-CLOSING COVENANTS

       Section 8.1 Use of Hornbeck Name. Tidewater shall use
  its  reasonable best efforts (a) to  remove  the  Hornbeck
  name and any abbreviation thereof and any associated trade
  or service marks from all vessels, real property, owned or
  leased,  and  equipment  upon  consummation  of the Merger
  (provided  that,  to  the  extent  any  such  vessels   or
  equipment  are  owned  or operated by the North Sea Group,
  Tidewater  shall  not  be deemed  to  have  breached  this
  covenant if it is prevented  from  effecting such removal)
  and  (b) to take all other steps reasonably  necessary  to
  avoid  any  public  use of the Hornbeck name in connection
  with the operation of  its business following the Closing,
  including  the  removal of  the  Hornbeck  name  from  the
  corporate or other  organizational  name of the members of
  the Hornbeck Group (provided that, with respect to members
  of the North Sea Group, Tidewater shall  not  be deemed to
  
<PAGE> 46

  have  breached  this  covenant  if  it  is prevented  from
  effecting  such  removal),  in  each  case  as   soon   as
  practicable  but  in no event later than 60 days after the
  Closing Date.

       Section 8.2 Indemnification of Directors and Officers
  of Hornbeck.

            (a)   From and after the  Effective  Time of the
  Merger,  Tidewater  agrees to indemnify and hold harmless,
  and to cause Surviving  Corporation  to honor its separate
  indemnification  obligations  to, each person  who  is  an
  officer  or  director of Hornbeck  (or  a  member  of  the
  Hornbeck Group  serving at the request of Hornbeck) on the
  date of this Agreement or has served as such an officer or
  director at any time  since January 1, 1993 (together with
  those persons discussed  in  the  last  sentence  of  this
  subsection,  an "Indemnified Person") from and against all
  damages, liabilities,  judgments  and  claims (and related
  expenses  including, but not limited to,  attorney's  fees
  and amounts paid in settlement) based upon or arising from
  his or her  capacity as an officer or director of Hornbeck
  (or a member  of the Hornbeck Group serving at the request
  of Hornbeck), to the same extent he or she would have been
  indemnified under  the Certificate of Incorporation or By-
  laws of Hornbeck as  such  documents were in effect on the
  date of this Agreement.  Tidewater further agrees to honor
  the resolution regarding Hornbeck employee indemnification
  that  is referred to in Section  6.15  (but  only  to  the
  extent  such  resolution  has been modified as required by
  Section 6.15), to the extent the matter referred to in the
  first paragraph of Schedule  4.23(b) has not been resolved
  by the Closing Date.

            (b)   Tidewater  shall  pay  for  the  insurance
  premiums  required  for any extension  of  Hornbeck's  D&O
  insurance  policy  following   the   Closing  Date  for  a
  "discovery"  period  elected under such  insurance  policy
  covering the officers  and  directors  of  Hornbeck  (or a
  member  of  the  Hornbeck Group, serving at the request of
  Hornbeck), for a period  of  six  years  or  shall provide
  comparable coverage for the same period under  Tidewater's
  D&O  insurance  policy  for all directors and officers  of
  Hornbeck (or a member of  the  Hornbeck  Group, serving at
  the request of Hornbeck), covered by Hornbeck's policy.

            (c)   The  rights  granted  to  the  Indemnified
  Persons hereby shall be contractual rights  inuring to the
  benefit of all Indemnified Persons and shall  survive this
  Agreement  and any merger, consolidation or reorganization
  of Tidewater.

            (d)   The  rights  to indemnification granted by
  this Section 8.2 are subject to the following limitations:
  (i) the total aggregate indemnification  to be provided by
  Tidewater  and/or Surviving Corporation pursuant  to  this
  Section 8.2  will not exceed, as to all of the Indemnified
  Persons described  herein  as  a  group,  the  sum  of $50
  million, and Tidewater shall have no responsibility to any
  Indemnified  Person  for  the  manner in which such sum is
  allocated among that group (but  the  Indemnified  Persons
  may  seek  reallocation  among  themselves);  (ii) amounts
  otherwise  required  to  be  paid  by   Tidewater   to  an
  Indemnified  Person pursuant to this Section 8.2 shall  be
  reduced by any  amounts  that  such Indemnified Person has
  recovered by virtue of the claim for which indemnification
  is  sought  and  Tidewater  shall be  reimbursed  for  any
  amounts  paid by Tidewater that  such  Indemnified  Person
  subsequently  recovers  by  virtue of such claim; (iii) no
  Indemnified  Person shall be entitled  to  indemnification
  for any claim made or threatened prior to the Closing Date
  of which such Indemnified Person or Hornbeck was aware but
  did  not promptly  disclose  to  Tidewater  prior  to  the
  execution  of  this  Agreement, if the claim or threatened
  
  <PAGE> 47

  claim was known on or  before  such  time, or prior to the
  Closing Date, if such claim became known  after  execution
  of this Agreement, provided that all matters disclosed  in
  the  Schedules  to  this Agreement shall be deemed to have
  been disclosed to Tidewater  by  all  of  such Indemnified
  Persons  for  purposes  of this Section 8.2(d);  (iv)  any
  claim for indemnification  pursuant  to  this  Section 8.2
  must  be  submitted  in  writing  to  the  Chief Executive
  Officer of Tidewater promptly upon such Indemnified Person
  becoming aware of such claim and, in no event,  more  than
  ten  years from the Effective Date, provided that any such
  failure  to  advise  promptly  has a prejudicial effect on
  Tidewater; and (v) an Indemnified  Person shall not settle
  any  claim for which indemnification  is  provided  herein
  without the prior written consent of Tidewater.

            (e)   Tidewater  agrees that the indemnification
  limit set forth in subparagraph  (d)(i)  above  shall  not
  apply  to  any  damages, liabilities, judgments and claims
  (and  related  expenses,  including  but  not  limited  to
  attorney's fees and amounts paid in settlement) insofar as
  they arise out of  or  are  based upon any misstatement by
  Tidewater of a material fact in the Registration Statement
  or are based upon an omission  by  Tidewater of a material
  fact required to be stated therein,  or necessary in order
  to  make  a statement therein not misleading  unless  such
  statement or  omission was based upon information supplied
  by Hornbeck for inclusion therein.

       Section  8.3  Publication  of  Post-Merger   Results.
  Tidewater  shall use its reasonable best efforts to  cause
  financial results  covering  at least thirty days of post-
  Merger combined operations to  be  published  as  soon  as
  practicable after the passage of such thirty day period.

       Section  8.4  Employee   Benefits.    Following   the
  consummation  of  the  Merger,  Tidewater shall arrange to
  make generally available to the employees  of Hornbeck the
  benefits  listed  on Schedule 8.4 in accordance  with  the
  terms of such benefit  plans,  policies  or  arrangements,
  provided  that this covenant shall not prohibit  Tidewater
  from modifying  or  rescinding such benefits thereafter to
  the extent such modification  or  rescission  is generally
  applicable to Tidewater employees.

       Section 8.5  Registration Rights. Tidewater shall use
  its  reasonable  best  efforts  to  cause  a  Registration
  Statement  on  Form S-8 to be filed with the SEC  covering
  the shares of Tidewater  Common  Stock  to  be issued upon
  exercise of the Hornbeck Disclosed Employee Stock  Options
  (provided that no representation is made by Tidewater that
  any such Form S-8 Registration Statement will in all cases
  be available to permit resales of Tidewater Common Stock),
  or shall provide the holder of such options with piggyback
  registration rights for such shares.

  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

  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 so

  deprive that party of the right thereafter to insist  upon
  strict  adherence  to  that term or any other term of this
