of January 21, 2005 (the "Forbearance Date"), is made by and among OMNI ENERGY
SERVICES CORP., AMERICAN HELICOPTERS INC., OMNI ENERGY SERVICES CORP.-MEXICO,
TRUSSCO, INC., AND TRUSSCO PROPERTIES, LLC (collectively, "Maker" and each,
individually, a "Maker"), and BEAL BANK, S.S.B., a savings bank organized under
the laws of the State of Texas ("Payee"), and is based on the following recitals
of fact.

                                R E C I T A L S:

      A. The Maker is indebted to the Payee under a Promissory Note dated as of
October 22, 2004 (the "Note"; capitalized terms used in this Forbearance
Agreement but not defined herein shall have the same sense and meaning as in the
Note), among the Maker and the Payee. As of the Forbearance Date, the
outstanding principal balance of the Note is Six Million, Five Hundred Thousand
Dollars ($6,500,000.00) (the "Balance"). Unpaid interest continues to accrue
according to the terms of the Note, currently at the Default Rate. Additionally,
the Maker is obligated for other fees, costs, and expenses in accordance with
and as may be provided for in the Loan Documents.

      B. As of the date of this Forbearance Agreement, an Event of Default
exists under paragraph 7(a) of the Note as a result of the Maker's failure to
repay the Obligations owing to the Payee under the Note on the Final Maturity
Date (the "Existing Default").

      C. The Maker has requested that the Payee temporarily forbear from
exercising its available rights and remedies arising as a result of the Existing
Default and the Payee is willing to forebear from exercising such rights and
remedies conditioned upon and subject to the terms and conditions set forth in
this Forbearance Agreement.

                               A G R E E M E N T:

      For and in consideration of the mutual covenants herein, and other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Maker and the Payee agrees as follows:

      1. Recitals. The foregoing recitals are confirmed by the parties as true,
accurate, and correct and are incorporated herein by reference. The recitals are

            (a) Subject to the terms and provisions of this Forbearance
      Agreement (including without limitation, paragraph 6 and paragraph 7
      hereof), the Payee hereby agrees to forbear from exercising any of its
      rights and remedies arising under the Loan Documents or otherwise as a
      result of the Existing Default (the "Forbearance") for the period, and
      only for the period, commencing on the Forbearance Date through and
      including February 28, 2005 (the "Expiration Date") or such earlier date
      on which Payee's agreement to forbear pursuant hereto terminates (such
      period being referred to hereinafter as the "Forbearance Period").

            (b) Paragraph 2(a) of this Forbearance Agreement shall be limited
      strictly as written and this Forbearance Agreement does not constitute a
      forbearance with respect to any Event of Default other than the Existing
      Default and does not constitute a waiver of the Existing Default or any
      other Event of Default. In the event that prior to the end of the
      Forbearance Period any further Event of Default occurs under the Note
      (i.e., other than the Existing Default) or if the Maker shall breach any
      provision of this Forbearance Agreement or any Loan Document, then the
      Payee shall have the right and option, in its sole discretion and without
      notice to the Maker, to terminate its agreement to forbear pursuant to
      this Forbearance Agreement and to exercise any and all of its rights and
      remedies under the Loan Documents or otherwise arising as a result of such
      Event of Default or the Existing Default.

            (c) Notwithstanding anything contained herein to the contrary, and
      as an additional material inducement to the Payee to enter into this
      Forbearance Agreement, the Maker hereby agrees that, except as expressly
      set forth herein with respect to the Forbearance during the Forbearance
      Period, this Forbearance Agreement shall have no effect on, and shall not
      act as a waiver of, any Event of Default (including, without limitation,
      the Existing Default), or any rights or remedies resulting therefrom,
      whether now existing or hereafter arising, under the terms and provisions
      of the Loan Documents or otherwise whether known or unknown by the Payee.
      The Payee expressly reserves the right to, and may, at its option, declare
      any other Event of Default, except as expressly set forth herein.

      3. Liens. By this Forbearance Agreement, all liens, security interests,
assignments, superior titles, rights, remedies, powers, equities, and priorities
securing the Obligations (collectively, the "Outstanding Liens") are hereby
ratified and confirmed as valid, subsisting, and continuing to secure the
Obligations as amended to date, and this Forbearance Agreement shall not affect
the priority of any Outstanding Lien. Nothing in this Forbearance Agreement
shall in any manner diminish, impair, or extinguish any of the Outstanding Liens
or the Loan Documents or be construed as a novation in any respect. In addition,
the Maker acknowledges and agrees that this Forbearance Agreement constitutes a
Loan Document and that the obligations of the Maker hereunder (including,
without limitation, the obligation of Maker to repurchase the Stock, as
hereinafter defined, as provided in paragraph 7 (d) below) constitute
Obligations secured by the Outstanding Liens.

      7. Continuing Conditions. Payee's agreement to forbear pursuant to this
Forbearance Agreement is conditioned upon the Maker's compliance with each of
the following conditions. The Maker acknowledges and agrees that the Maker's
failure to fully comply with any of the following conditions shall constitute a
breach of the terms of this Forbearance Agreement which shall result in the
termination of the Payee's agreement to forbear.

            (a) Obligation to Remain Current. The Maker shall remain current in
      the payment of all interest and other fees and expenses as provided by the
      Note, any other Loan Document and this Forbearance Agreement.

            (b) Applicable Interest Rates. Interest on the outstanding principal

      lesser of (x) the Highest Lawful Rate or (y) the Default Rate.

            (c) Payments. In addition to the payments required by paragraphs 6
      (b) and (c) above, on January 28, 2005, Maker shall pay to Payee an
      additional Two Hundred Fifty Thousand Dollars ($250,000.00), with such
      payment being applied first to accrued and unpaid interest on the Note and

            (d) Payment in Stock; Obligation to Purchase. Subject to
      satisfaction of the conditions set forth below, the Maker's obligation to

      principal balance of the Note, and interest thereon, due and payable on
      the last day of the Forbearance Period) may be satisfied by the delivery
      to the Payee, on the date the payment in question is due, of fully
      registered, publicly traded, unrestricted common stock ("Stock") of OMNI
      Energy Services Corp., or, if Maker is unable to deliver such Stock as
      fully registered, unrestricted shares, by delivery to the Payee of
      privately issued restricted shares of Stock, in each case, registered in
      the name of Payee or its nominee, valued at the lesser of (i) the closing
      price of the Stock on the NASDAQ Stock Market on the last day the Stock
      was trading on such market prior to the due date of such payment or (ii)
      the opening price of the Stock on such market on the date such payment is
      due, in each case rounded up to the next highest whole number of shares of
      Stock. If the shares of Stock are privately issued, restricted shares,
      Maker shall cause OMNI Energy Services Corp. to prepare and file a
      registration statement on Form S-3, or other appropriate form, to register
      the resale of such Stock, and to use its best efforts to cause such
      registration statement to be declared effective on or before the last day
      of the Forbearance Period. The issuer shall cause the registration
      statement to continue in effect until such time that the Payee (and/or its
      nominee and/or successor or assign) has disposed of all the Stock or that
      it may be entitled to dispose of all of the Stock without any restrictions
      or limitations under the securities laws. On or prior to the Expiration
      Date, Payee may, with one business day's prior notice to Maker, require
      that Maker

FORBEARANCE AGREEMENT - Page 4

<PAGE>

      purchase the Stock issued to Payee as aforesaid by delivery to Payee by
      wire transfer in same day funds U.S. Dollars equal to the value of such
      Stock valued at the higher of (x) the value determined under clauses (i)
      or (ii) of the preceding sentence or (y) the then current market price of
      the Stock. The rights of Maker set forth in this paragraph (d) to make the
      above-described payment to Payee by the delivery of the Stock is
      conditioned and contingent upon Payee agreeing, at or prior to the time
      such Stock is offered to Payee, that it will accept such Stock, and if
      Payee does not agree in writing to so accept such Stock, Maker shall have
      no right to make such payment by delivering such Stock to Payee and Payee
      will have no obligation to accept such Stock. Payee may make its
      determination of whether to accept such Stock in payment of the amounts
      due as set forth in this paragraph (d) in Payee's sole discretion.

            (e) Notice of Payment. If Maker elects to pay all amounts due under
      the Note, the other Loan Documents and this Forbearance Agreement prior to
      the last day of the Forbearance Period, Maker must give the Payee no less
      than 5 business days' prior written notice of such payment. Once given,
      such notice will be irrevocable and the Note shall be due and payable on
      the date prior to the last day of the Forbearance Period as provided in
      such notice.

      8.    Representations and Warranties. In order to induce the Payee to
execute, deliver, and perform this Forbearance Agreement, the Maker warrants and
represents to the Payee each and every of the following:

            (a) This Forbearance Agreement is not being made or entered into
      with the actual intent to hinder, delay, or defraud any entity or person,
      and the Maker is solvent and is not bankrupt.

            (b) This Forbearance Agreement is not intended by the parties to be
      a novation of the Loan Documents and, except as expressly modified herein,
      all terms, conditions, rights, and obligations as set out in the Loan
      Documents are hereby reaffirmed and shall otherwise remain in full force
      and effect as originally written and agreed.

            (c) No action or proceeding, including, without limitation, a
      voluntary or involuntary petition for bankruptcy under any chapter of the
      United States Bankruptcy Code (the "Bankruptcy Code"), has been instituted
      by or against any Maker or threatened against any Maker.

            (d) The execution of this Forbearance Agreement by the Maker and the
      performance by the Maker of its respective obligations hereunder will not
      violate or result in a breach or constitute a default under any agreement
      to which it is a party.

            (e) All information provided by the Maker to the Payee prior to the
      Forbearance Date, including, without limitation, all representations and
      warranties made and given by any Maker in the Loan Documents, all
      financial statements, balance sheets, and cash flow statements, was, at
      the date of delivery, and is, as of the date hereof, true,

FORBEARANCE AGREEMENT - Page 5

<PAGE>

      accurate, and correct in all respects. The Maker recognizes and
      acknowledges that the Payee is entering into this Forbearance Agreement
      based in part on the financial information provided to the Payee by the
      Maker and that the truth and correctness of that financial information is
      a material inducement to the Payee in entering into this Forbearance
      Agreement. During the term of this Forbearance Agreement, the Maker agrees
      to advise the Payee promptly in writing of any and all new information,
      facts, or occurrences which would in any way materially supplement,
      contradict, or affect any financial statements, balance sheets, cash flow
      statements, or similar items furnished to the Payee.

            (f) Other than the Existing Default, no Default or Event of Default
      under any Loan Document has occurred and is continuing, and no event has
      occurred and is continuing which, with notice or the passage of time or
      both, would be a Default or an Event of Default.

            (g) The Maker lawfully possesses and holds a 100% ownership interest
      in all of the Collateral for the Obligations, free and clear of any Lien,
      defect, reservation of title, or conditional sales contract, and also of
      any security interest, other than the Outstanding Liens in favor of the
      Payee or Permitted Encumbrances. There is no financing statement affecting
      any real, personal, tangible, or intangible property ("Property") of the
      Maker on file in any public office except for financing statements in
      favor of the Payee and any relating to Permitted Encumbrances.

            (h) Since the inception of the Obligations, there have been no
      changes in the organization, composition, material ownership, structure,
      or formation documents of any Maker which has not been disclosed in
      writing to the Payee; in each state in which any Maker does business, it
      is properly licensed, in good standing, and, where required, in compliance
      with fictitious name statutes.

            (i) Execution, delivery, and performance of this Forbearance
      Agreement, and any instrument or agreement required hereunder, are within
      each Maker's powers, have been duly authorized, and do not conflict with
      any of its organizational papers.

            (j) The Loan Documents to which the Maker is a party, including this
      Forbearance Agreement, are legal, valid, and binding agreements of the
      Maker, enforceable in accordance with its respective terms, and any
      instrument or agreement required hereunder or thereunder, when executed
      and delivered, will be similarly legal, valid, binding, and enforceable;
      this Forbearance Agreement does not conflict with any law, agreement, or
      obligation by which the Maker is bound.

      9. Reaffirmation. Each Maker reaffirms all of its obligations under the
Loan Documents to which it is a party.

      10. Termination of Forbearance and Rights in the Event of Bankruptcy.

FORBEARANCE AGREEMENT - Page 6

<PAGE>

            (a) Notwithstanding anything to the contrary in this Forbearance
      Agreement, the obligations of the Payee to forbear from exercising any of
      its rights and remedies arising under the Loan Documents or otherwise as a
      result of the Existing Default shall terminate upon the filing of any
      proceeding, voluntarily or involuntarily, under Title 11 of the United
      States Code or any other state or federal statute seeking the
      reorganization, liquidation or restructuring of any Maker, or the filing
      by any person of any legal, administrative or arbitration proceeding
      seeking the reorganization, liquidation, dissolution, restructuring,
      foreclosure, appointment of a receiver or transfer of control or
      possession of the assets of any Maker for the benefit of a creditor. In
      the event of any such filing, all obligations, covenants, representations,
      warranties and releases of and/or granted by the Maker, and the Maker's
      shareholders shall remain in full force and effect.

            (b) All of the above terms and conditions have been freely bargained
      for and are all supported by reasonable and adequate consideration and the
      provisions herein are material inducements for the Payee entering into
      this Forbearance Agreement.

      11. Waiver of Claims and Defenses. To induce the Payee to enter into this
Forbearance Agreement, each Maker represents and warrants to Payee that as of
the Forbearance Date there are no claims or offsets against or defenses or
counterclaims to their respective obligations under the Loan Documents, and each
Maker waives any and all such claims, offsets, defenses, or counterclaims
whether known or unknown, arising prior to the Forbearance Date. Additionally,
each Maker, on behalf of itself and its shareholders/owners, hereby releases and
agrees to hold the Payee, and each of its legal representatives, successors,
affiliates, parents, subsidiaries, predecessors, assigns, shareholders,
partners, trustees, beneficiaries, administrators, heirs, former and current
officers, directors, agents, attorneys, and employees, and their respective
successors, assigns, heirs, executors, and administrators harmless from any and
all claims, actions, suits, causes of action, accounts, judgments, agreements,
promises, executions, debts, damages, demands, rights, obligations, liabilities,
and controversies now in existence concerning or in connection with the Note,
this Forbearance Agreement, or any other Loan Documents (collectively, the
"Claims") of every nature and description, at law or in equity, whether known or
unknown, foreseen or unforeseen, and regardless of whether the Maker, or any
other person hereafter discovers any fact which may give rise to any of the
Claims.

      12. Acknowledgments. Each Maker hereby acknowledges and agrees that:

            (a) No Future Obligations. The Payee has no obligation to make any
      additional loan or extension of credit to or for the benefit of the Maker,
      and no obligation to extend the maturity date of any credit extended to
      the Maker.

            (b) No Third Party Beneficiaries. This Forbearance Agreement is not
      intended for, and shall not be construed to be for, the benefit of any
      person not a signatory hereto.

<PAGE>

      13. Impairment/Security. Except as otherwise specifically set forth
herein, the Loan Documents shall each remain unaffected by this Forbearance
Agreement and all such Loan Documents shall remain in full force and effect. The
Maker's payment and performance of its various obligations to the Payee under
the Loan Documents (including, without limitation, this Forbearance Agreement),
including all extensions, amendments, renewals, or replacements thereof,
continue to be and shall be secured by the Outstanding Liens. Nothing contained
herein shall be deemed a waiver of any of the rights and remedies that the Payee
may have against any Maker, or of the Payee's rights and remedies arising out of
the Loan Documents.

      14. Severability. If any court of competent jurisdiction determines any
provision of this Forbearance Agreement or any provision in any of the other
Loan Documents to be invalid, illegal, or unenforceable, that portion shall be
deemed severed from the rest, which shall remain in full force and effect.

      15. Attorneys' Fees. If any lawsuit, reference, or arbitration is
commenced which arises out of or relates to the Obligations or any of the Loan
Documents, the prevailing party shall be entitled to recover from each other
party such sums as the court, referee, or arbitrator may adjudge to be
reasonable attorneys' fees in the action, reference, or arbitration, in addition
to costs and expenses otherwise allowed by law. In all other situations,
including any matter arising out of or relating to any bankruptcy or insolvency
proceeding, the Maker agrees to pay all of the Payee's costs and expenses,
including attorneys' fees (including, without limitation, the allocated costs of
in-house counsel), which may be incurred in enforcing or protecting the Payee's
rights or interests. From the time(s) incurred until paid in full to the Payee,
all such sums shall bear interest at the rate specified in paragraph 7(b)
hereof.

      16. Miscellaneous.

            (a) Counterparts. This Forbearance Agreement may be executed in a
      number of identical counterparts which, taken together, shall constitute
      collectively one agreement; but in making proof of this Forbearance
      Agreement, it shall not be necessary to produce or account for more than
      one such counterpart executed by the party to be charged.

            (b) Amendments, etc. Any future waiver, alteration, amendment, or
      modification of any of the provisions of the Loan Documents or this
      Forbearance Agreement shall not be valid or enforceable unless in writing
      and signed by all parties, it being expressly agreed that neither the Loan
      Documents, nor this Forbearance Agreement can be modified orally, by
      course of dealing, or by implied agreement. Moreover, any delay by the
      Payee in enforcing its rights after a Default or an Event of Default shall
      not be a release or waiver of the Default or the Event of Default and
      shall not be relied upon by the Maker as a release or waiver of the
      Default or Event of Default. Except as specifically provided in this
      Forbearance Agreement, no express or implied consent to any further
      forbearance or modifications involving any of the matters set forth in
      this
