ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

  On May 6, 1999, the Investors acquired 4,000,000 shares of Common Stock
pursuant to a Purchase Agreement, dated as of April 16, 1999 (the "Purchase
Agreement"), 96.663% of which were acquired by the Fund and 3.337% of which were
acquired by the Executive Fund.  The aggregate purchase price for the shares
sold under the Purchase Agreement was $25,000,000. The Fund utilized funds
derived from capital contributions made by the partners of the Fund. The
Executive Fund utilized funds derived from capital contributions made by the
partners of the Executive Fund.  Subject to approval by the stockholders of the
Issuer, the Purchase Agreement provides for the purchase of an additional
4,000,000 shares of Common Stock by the Investors (see Item 4 below).

                              Page 16 of 22 pages
<PAGE>

  A copy of the Purchase Agreement is attached hereto as Exhibit A and is
incorporated by reference herein.

ITEM 4.  PURPOSE OF TRANSACTION.

  Each of the Fund and the Executive Fund acquired and continues to hold the
shares of Common Stock reported herein for investment purposes.

  Subject to the requisite approval of the stockholders of the Issuer, the
Investors currently intend either to assign their rights to purchase the
additional 4,000,000 shares of Common Stock to certain of the Fund's limited
partners or to purchase such shares through a new entity with funds derived from
capital contributions made by certain of the Fund's limited partners.

  The Fund and the Executive Fund may, in the future, have discussions with
management, directors and other shareholders of the Issuer concerning various
ways of maximizing long-term stockholder value.  In connection with the
transactions described herein, the Issuer and the Investors entered into a
Stockholders' Agreement dated May 6, 1999 (the "Stockholders' Agreement")
pursuant to which the size of the Board of Directors of the Issuer (the "Board")
was increased from six to eight and two designees of the Investors were
appointed to the Board effective May 6, 1999.

  Other than the purchase of any of the additional 4,000,000 shares of Common
Stock subject to stockholder approval as described above, the Reporting Persons
currently do not intend to acquire additional shares of Common Stock or other
securities of the Issuer.  Depending on market conditions and other factors that
the Fund or the Executive Fund may deem material to its investment decision, the
Fund or the Executive Fund may purchase additional shares of Common Stock or
other securities of the Issuer in the open market or in private transactions.
Depending on these same factors, the Fund or the Executive Fund may sell all or
a portion of the shares of Common Stock that they now own or hereafter may
acquire on the open market or in private transactions.

  Except as set forth above in Item 4, none of the Reporting Persons nor, to the
best of Reporting Person's knowledge, none of the executive officers or
directors of such Reporting Persons, as applicable, has any plans or proposals
that relate to or would result in any of the actions specified in clauses (a)
through (j) of Item 4 to Schedule 13D.

  A copy of the Stockholders' Agreement is attached hereto as Exhibit B and is
incorporated herein by reference.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

  At the close of business on May 6, 1999, the Fund and the Executive Fund had
direct beneficial ownership of 4,000,000 shares of Common Stock.  The Reporting
Persons constitute a "group" for purposes of Section 13(d)(3) of the Act, and
therefore, each Reporting Person is deemed to have beneficial ownership of
4,000,000 shares of Common Stock (the "Shares"). Such ownership represents 16.4%
of the Common Stock outstanding based on the number of

                              Page 17 of 22 pages
<PAGE>

shares of Common Stock outstanding (20,378,416) as contained in the Issuer's
Definitive Proxy Statement on Schedule 14A (filed May 10, 1999) and including as
outstanding the 4,000,000 shares of Common Stock issued to the Fund and the
Executive Fund. Such securities were acquired pursuant to the transactions
described in Item 3 hereof.

  Each of the Reporting Persons has shared voting and dispositive power with
respect the Shares.

  No person other than the Reporting Persons has the right to receive or the
power to direct the receipt of dividends from, or the proceeds from the sale of,
the Shares.

ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
TO SECURITIES OF THE ISSUER.

  Reference is made to the information disclosed under Items 2, 3 and 4 of this
Statement which is incorporated by reference in response to this Item.

  Pursuant to the Stockholders' Agreement, the Issuer granted certain
registration rights to the Investors with respect to the Shares.  These rights

registration rights, each as set forth in the Stockholders' Agreement.

respect to such permits and no event has occurred which allows, or after
notice or lapse of time would allow, revocation or termination thereof or
could result in any other material impairment of the rights of the holder of
any such permit, except as could not reasonably be expected to have a Material
Adverse Effect. Except as described in the SEC Documents, such permits contain
no restrictions that are or will be materially burdensome to the Company or
such Subsidiary, as the case may be.

penalty or excise tax provisions of the Code relating to employee benefit
plans (as defined in Section 3 of ERISA), and no event, transaction or
condition has occurred or exists that could reasonably be expected to result
in the incurrence of any such liability by the Company or any ERISA Affiliate,
or in the imposition of any Lien on any of the rights, properties or assets of
the Company or any ERISA Affiliate, in either case pursuant to Title I or IV
of ERISA or to such penalty or excise tax provisions or to Section 401(a)(29)

"Intellectual Property") presently employed by it in connection with the
businesses now operated by it free and clear of and without violating any
right, claimed right, charge, encumbrance, pledge, security interest,
restriction or lien of any kind of any other person, except where the failure
to own, possess, license or have the right to employ its Intellectual Property
could not reasonably be expected to have a Material Adverse Effect. To the
Company's Knowledge, the Company will not suffer any Material Adverse Effect
with respect to Year 2000 non-compliance.

  Section 3.18 Environmental Matters. Neither the Company nor any of its
Subsidiaries has violated any foreign, federal, state or local law or

Adverse Effect. Such insurance insures against such losses and risks as are
adequate in accordance with customary industry practice to protect the Company
and its Subsidiaries and their respective businesses, except as could not
reasonably be expected to have a Material Adverse Effect. Neither the Company
nor its Subsidiaries has received notice from any insurer or agent of such
insurer that substantial capital improvements or other material expenditures
will have to be made in order to continue such insurance. All such insurance
is outstanding and duly in force on the date hereof, subject only to changes
made in the ordinary course of business, consistent with past practice, that

of each of the Company and its Subsidiaries exceeds the amount that it will be
required to be paid on or in respect of its existing debts and other
liabilities (including contingent liabilities) as they become absolute and
matured. The assets of each of the Company and its Subsidiaries do not
constitute unreasonably small capital to carry out its business as conducted

opinion of counsel which opinion shall be reasonably satisfactory in form and
substance to the Company, to the effect that such Transfer is being made

from, or in a transaction not subject to, the registration requirements of the
Securities Act and any applicable state or foreign securities laws. Such

  PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT AND
  APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN APPLICABLE EXEMPTION
  FROM THE REGISTRATION REQUIREMENTS OF SUCH ACT AND SUCH LAWS.

  The legends set forth above may be removed if and when the Shares
represented by such certificate are disposed of pursuant to an effective
registration statement under the Securities Act or the opinion of counsel
referred to above has been provided to the Company. The Share Certificates
shall also bear any additional legends required by applicable federal, state
or foreign securities laws, which legends may be removed when, in the opinion
of counsel to the Company, the same are no longer required under the
applicable requirements of such securities laws. Such Purchaser agrees that,
in connection with any Transfer of Shares by it pursuant to an effective
registration statement under the Securities Act, it will comply with all

representation, warranty or agreement as to the availability of any exemption
from registration under the Securities Act with respect to any resale of
Shares.

  warranty, covenant or agreement contained in this Agreement which (A) would
  give rise to the failure of a condition set forth in Section 6.2 or 6.3,
  and (B) cannot be cured or, if curable, has not been cured within 20 days
  (the "Cure Period") following receipt by the breaching party of written
  notice of such breach;

    (2) if a court of competent jurisdiction or other Governmental Entity
  shall have issued an order, decree, or ruling or taken any other action
  (which order, decree, or ruling the Purchasers and the Company shall use
  all commercially reasonable efforts to lift), in each case permanently
  restraining, enjoining, or otherwise prohibiting the transactions
  contemplated by this Agreement, and such order, decree, ruling, or other
  action shall have become final and nonappealable; provided, however, that
  the right to terminate this Agreement under this clause (2) shall not be
  available to any party whose breach of this Agreement has been the cause
  of, or resulted in, such order, decree, ruling or other action; or

    (3) if the First Closing shall not have occurred by May 15, 1999,
  provided, however, that the right to terminate this Agreement under this
  clause (3) shall not be available to any party whose breach of this
  Agreement has been the cause of, or resulted in, the failure of the First
  Closing to occur on or before such date.

  Unless agreed to otherwise in writing by the Purchasers and the Company,
this Agreement shall automatically terminate on September 30, 1999 if the
stockholder approval contemplated in Section 5.9 has not been obtained.

  The right of any party hereto to terminate this Agreement pursuant to this
Section 8.1 shall remain operative and in full force and effect regardless of
any investigation made by or on behalf of any party hereto, any person
controlling any such party or any of their respective officers, directors,
employees, accountants, consultants, legal counsel, agents, or other
representatives whether prior to or after the execution of this Agreement.

  Section 8.2 Effect of Termination. In the event of the termination of this
Agreement, written notice thereof shall forthwith be given to the other party
specifying the provision hereof pursuant to which such termination is made,
unless such termination has occurred due to the lapse of time, and, except in
the case of a termination pursuant to Section 8.1(b)(1), this Agreement
(except for the provisions of this Section 8.2, and Sections 5.1, 10.5, 10.6,
10.9, 10.10, 10.11, 10.12, and 10.13, which shall survive such termination)

the Purchasers as provided above, other than a termination pursuant to Section
8.1(b)(1), there shall be no liability on the part of the Company or the
Purchasers; provided, however, that nothing in this Section 8 shall be deemed
to release either party from any breach by such party of the terms and
provisions of this Agreement or to impair the right of either party to compel
specific performance by the other party of its obligations under this
Agreement.

                                 Miscellaneous

  Section 10.1 Survival of Provisions.

  (a) The representations and warranties of the Company and the Purchasers
made herein or in the Stockholders' Agreement and the covenants of the Company
and the Purchasers to be complied with on or prior to the First Closing Date,
the Second Closing Date or September 30, 1999, as the case may be, shall
remain operative and in full force and effect pursuant to their terms,
regardless of (1) any investigation made by or on behalf of the Purchasers or
the Company, as the case may be, or (2) acceptance of any of the Shares and
payment by the Purchasers therefor, until April 16, 2002; provided, however,
that the representations and warranties of the Company made in Sections 3.1,
3.3 and 3.4 shall not terminate.

  Section 10.2 No Waiver; Modification in Writing. No failure or delay on the
part of the Company or a Purchaser in exercising any right, power or remedy
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right, power or remedy preclude any other or further
exercise thereof or the exercise of any other right, power or remedy. Without
limiting the rights that any party may have for fraud under common law, and
except with respect to claims arising from or liability based on a breach of
the Company's representation and warranty in Section 3.5(a), the remedies
provided for herein are cumulative and are the exclusive remedies available to
the Company or the Purchasers at law or in equity. The provisions of this
Agreement, including the provisions of this sentence, may not be amended,
modified or supplemented, and waivers or consents to departures from the
provisions hereof may not be given without the written consent of the Company,
on the one hand, and the Purchasers or their permitted assigns, on the other
hand; provided that notice of any such waiver shall be given to each party
hereto as set forth below. Any amendment, supplement or modification of or to
any provision of this Agreement, or any waiver of any provision of this
Agreement, shall be effective only in the specific instance and for the
specific purpose for which made or given. Except where notice is specifically
required by this Agreement, no notice to or demand on any party hereto in any
case shall entitle the other party to any other or further notice or demand in
similar or other circumstances.

  Section 10.3 Specific Performance. The parties recognize that in the event
the Company or the Purchasers should refuse to perform under the provisions of
this Agreement, monetary damages alone will not be adequate. The Purchasers or
the Company, as the case may be, shall therefore be entitled, in addition to
any other remedies which may be available, including money damages, to obtain
specific performance of the terms of this Agreement, without any requirement
for the posting of any bond. In the event of any action to enforce this
Agreement or the Stockholders' Agreement specifically, the Company and the
Purchasers hereby waive the defense that there is an adequate remedy at law.

  Section 10.4 Severability. If any term or other provision of this Agreement
is invalid, illegal, or incapable of being enforced by any rule of applicable
law, or public policy, all other conditions and provisions of this Agreement
shall nevertheless remain in full force and effect so long as the economic or
legal substance of the transactions contemplated herein are not affected in
any manner materially adverse to any party. Upon such determination that any
term or other provision is invalid, illegal, or incapable of being enforced,
the parties hereto shall negotiate in good faith to modify this Agreement so
as to effect the original intent of the parties as closely as possible in a
mutually acceptable manner in order that the transactions contemplated herein
are consummated as originally contemplated to the fullest extent possible.

and any other advisors thereto, arising out of or relating to the negotiation,
execution, delivery and consummation of this Agreement.

any nature whatsoever under or by reason of this Agreement.

disability, resignation, retirement or removal of any Director designated by
the Purchaser Representative, the Purchaser Representative shall designate an
individual to fill such vacancy, with such appointee to serve for the
remainder of the term of the Director whose death, disability, resignation,
retirement or removal caused such vacancy.

  Section 2.2 Trico Actions. Trico hereby agrees to take all necessary or
appropriate action to assist in the nomination for election as Directors the
person or persons designated by the Purchaser Representative pursuant to the
provisions of Section 2.1. Trico shall vote all management proxies in favor of
such nominees, except for such proxies that specifically indicate to the
contrary. Trico shall unanimously recommend, through its officers and
Directors, that its stockholders vote in favor of such nominees, and shall use
its reasonable best efforts to solicit from its stockholders proxies voted in
favor of such nominees.

                                   ARTICLE 3

                   Acquisition and Sale of Trico Securities

  Section 3.1. Trico Securities. The Purchasers covenant and agree with Trico
that except for the Trico Securities acquired pursuant to the Purchase
Agreement, the Purchaser Group shall not, without the prior consent of the
Board, directly or indirectly, acquire, become the beneficial owner of or
obtain any rights in respect of any additional Trico Securities, if the effect
of such acquisition, agreement or other action would be to increase the
aggregate beneficial ownership of Trico Securities by the Purchaser Group
after the completion of the transactions contemplated by the Purchase
Agreement. Notwithstanding the foregoing, the Purchaser Group shall not be
obligated to dispose of any Trico Securities beneficially owned in violation
of such maximum percentage limitation if, and solely to the extent that, the
aggregate beneficial ownership of the Purchaser Group is or will be increased
solely as the result of a recapitalization of Trico, a repurchase of any Trico
Securities by Trico or any of its subsidiaries, or any other action taken by
Trico or its Affiliates (other than the Purchaser Group).

  Section 3.2 Distribution of Trico Securities. Each of the Purchasers
covenants that it shall not, and that it shall cause all of its Affiliates and
Partners not to, directly or indirectly, sell, transfer any beneficial
interest in, or beneficial ownership of, pledge, hypothecate or otherwise
dispose of any Trico Securities, except:

  (a) in such amounts as would not cause the rights issued pursuant to the
Trico Rights Agreement to become exercisable under the Trico Rights Agreement;
or

  (b) pursuant to:

    (1) a bona fide pledge of or the granting of a security interest or any
  other lien or encumbrance in such Trico Securities to a lender that is not
  a member of the Purchaser Group to secure a bona fide loan for money
  borrowed made to one or more members of the Purchaser Group, the
  foreclosure of such pledge or security interest or any other lien or
  encumbrance that may be placed involuntarily upon any Trico Securities, or
  the subsequent sale or other disposition of such Trico Securities by such
  lender or its agent;

    (2) a transfer, assignment, sale or disposition of such Trico Securities
  to another member of the Purchaser Group;

    (3) a distribution of Trico Securities to any member of the Purchaser
  Group; provided that any arrangements coordinated or initiated by or on
  behalf of a member of the Purchaser Group to assist its limited partners in
  the sale of Trico Securities distributed to them must comply with the
  provisions of this Section 3.2;

    (4) sales in public offerings registered under the Securities Act
  pursuant to Article V;

    (5) sales effected in compliance with the provisions of Rule 144 under
  the Securities Act; and

                                      B-4
<PAGE>

    (6) other privately negotiated sales of Trico Securities, except for
  sales to Persons with their primary operations in the oilfield services
  industry that acquire 5% or more of the aggregate outstanding Trico
  Securities.

Notwithstanding anything to the contrary in this Section 3.2, in effecting any
sale, transfer of any beneficial interest in or other disposition of Trico
Securities pursuant to Sections 3.2(c)(3), (4), (5) and (6), above, the
members of the Purchaser Group selling, transferring or disposing such Trico
Securities shall use their reasonable best efforts to refrain from selling,
transferring or disposing of such number of Trico Securities as would cause
the rights issued pursuant to the Trico Rights Agreement to become exercisable
under the Trico Rights Agreement.

  Section 3.3. Proxy Solicitations. Each Purchaser covenants that it shall
not, and that no other member of the Purchaser Group shall, without the
consent of the Board, (a) solicit proxies or assist any other Person in the
solicitation of proxies for any proposal that would result in a change of
control of Trico; (b) publicly suggest or announce its willingness or desire
to engage in a transaction or group of transactions or have another Person
engage in a transaction or group of transactions that would result in a change
of control of Trico; (c) present to any third party any proposal that can
reasonably be expected to result in a change of control of Trico; (d)
initiate, induce or give encouragement to any other Person to initiate any
proposal that can reasonably be expected to result in a change of control of
Trico; or (e) directly or indirectly encourage, act as a financing source for
or otherwise invest in any other Person in connection with any of the
foregoing. For purposes of this Section 3.3, a "change of control" shall mean
the election to the Board at any one meeting at which Directors are elected of
such number of new directors that would constitute a majority of the number of
Directors comprising the Board subsequent to such meeting or the acquisition
by a Person or group within the meaning if Rule 13d-5 under the Exchange Act
of 50% or more of the outstanding Common Stock.

                        Legend And Stop Transfer Order

  Section 4.1 Legend and Stop Transfer Order. To assist in effectuating the
provisions of this Agreement, the Purchasers hereby consent:

  (a) to the placement, on certificates issued with respect to the shares of
Common Stock issued to them pursuant to the Purchase Agreement or otherwise
promptly after any Trico Securities become subject to the provisions of this
Agreement, of the following legend on all certificates representing ownership
of Trico Securities owned of record by any member of the Purchaser Group or by
any Person where a member of the Purchaser Group is the beneficial owner
thereof, until such shares are sold, transferred or disposed in a manner
permitted hereby to a Person who is not then a member of the Purchasers:

  The shares represented by this certificate are subject to the provisions of
  a Stockholders' Agreement among, inter alia, Trico Marine Services, Inc.
  and the Purchasers specified therein, and may not be sold, transferred,
  pledged, hypothecated or otherwise disposed of except in accordance
  therewith. Copies of the Agreement are on file at the office of the
  Corporate Secretary of Trico Marine Services, Inc.; and

  (b) to the entry of stop transfer orders with the transfer agent or agents
of Trico Securities against the transfer of Trico Securities except in
compliance with the requirements of this Agreement, or if Trico acts as its
own transfer agent with respect to any Trico Securities, to the refusal by
Trico to transfer any such securities except in compliance with the
requirements of this Agreement. Trico agrees to remove promptly all legends
and stop transfer orders with respect to the transfer of Trico Securities
being made to a Person who is not then a member of the Purchaser Group in
compliance with the provisions of this Agreement.

                       Registration Rights and Rule 144

  Section 5.1 Demand Registration.

  (a) At any time after November 6, 1999, the Purchaser Representative may at
any time and from time to time make a written request for registration under
the Securities Act of not less than 20% of the Registrable Securities owned by
the Purchaser Group (a "Demand Registration"); provided that Trico shall not
be obligated to effect more than an aggregate of three (3) Demand
Registrations pursuant to this Section 5.1(a). Such request will specify the
number of shares of Registrable Securities proposed to be sold and will also
specify the intended method of disposition thereof. Notwithstanding the
foregoing, Trico shall have the right, but no more frequently than once in any
consecutive twelve-month period, to be excused from its obligation to effect a
registration pursuant to this Section 5.1(a) during any period within such
twelve-month period starting with a date sixty (60) days prior to Trico's
estimated date of filing of, and ending on a date six (6) months following the
effective date of, a registration statement pertaining to an underwritten
public offering of securities for the account of Trico; provided that Trico is
actively employing in good faith all reasonable best efforts to cause such
registration statement to become effective and that Trico's estimate of the
date of filing of such registration statement is made in good faith. A
registration will not count as a Demand Registration until it has become
effective; provided, however, that a Demand Registration that is either
withdrawn or not declared effective at the Purchaser Representative's request
shall count as a Demand Registration unless Participating Purchasers also bear
all of the expenses specified in Section 5.6 hereof (including those otherwise
payable by Trico) with respect to such Demand Registration.

  (b) If the Purchaser Representative so elects, the offering of such
Registrable Securities pursuant to such Demand Registration shall be in the
form of an underwritten offering. The Company shall select the managing
underwriters and any additional investment bankers and managers to be used in
connection with the offering; provided that such managing underwriters and
additional investment bankers must be reasonably satisfactory to the Purchaser
Representative.

  Section 5.2 Shelf Registration.

  (a) The Purchaser Representative shall have the continuing right until the
Termination Date, but no more frequently than once in any consecutive twelve-
month period, to require Trico to prepare and file short-form Registration
Statements on Form S-3 with the SEC relating to the resale from time to time
of the Registrable Securities by the Purchaser Group in accordance with the
plan and method of distribution set forth in the Prospectus forming part of
such Registration Statement (a "Shelf Registration"); provided, however, that
Trico shall not be required to file a Shelf Registration unless Trico
Securities to be registered thereunder have an aggregate value of not less
than $3 million.

  (b) Trico agrees to use its reasonable best efforts to keep each Shelf
Registration continuously effective until the first to occur of (1) the date
that is 90 days after the Registration Statement is declared effective by the
SEC and (2) the date on which all of the Registrable Securities covered by the
Shelf Registration have been sold pursuant thereto.

  (c) Each Purchaser agrees that it will not, and that no other member of the
Purchaser Group will, sell any Registrable Securities pursuant to the Shelf
Registration during any Suspension Period. Trico agrees to cause any
Suspension Period to end as soon as reasonably practicable.

  Section 5.3 Piggyback Registration. If Trico proposes to file a registration
statement under the Securities Act with respect to an offering of Common Stock
(a) for Trico's own account (other than a registration statement on Form S-4
or S-8 (or any substitute form that may be adopted by the SEC)) or (b) for the
account of any of its holders of Common Stock (other than the Purchaser
Group), then Trico shall give written notice of such proposed filing to the
Purchaser Representative as soon as practicable (but in no event less than 15
days before the

                                      B-6
<PAGE>

anticipated filing date), and such notice shall offer the Purchaser Group the
opportunity to register such number of shares of Registrable Securities as the
Purchaser Representative may request on the same terms and conditions as
Trico's or such holder's Common Stock (a "Piggyback Registration"). Trico
shall use its reasonable best efforts to promptly cause all such Registrable
Securities to be registered along with the other shares of Common Stock to be
registered, if any.

  Section 5.4 Reduction of Offering. Notwithstanding anything contained
herein, if the managing underwriter of an offering described in Section 5.3
delivers a written opinion to Trico that the size of the offering that the
Purchaser Group, Trico and any other Persons whose securities are included in
such offering intend to make is such that the success of the offering would be
materially and adversely affected, then the amount of Registrable Securities
to be offered for the account of any Person other than the Purchasers shall be
reduced to the extent necessary to reduce the total amount of Common Stock to
be included in such offering to the amount recommended by such managing
underwriter. If such a reduction in the amount of Registrable Securities to be
offered for the account of any Person other than the Purchaser Group,
including a reduction of such amount to zero, is not sufficient to reduce the
total amount of Common Stock to be included in such offering to the amount
recommended by such managing underwriter, then, and only then, shall the
amount of Registrable Securities to be offered for the account of the
Purchaser Group be reduced to the extent necessary to reduce the total amount
of Common Stock to be included in such offering to the amount recommended by
such managing underwriter. Notwithstanding the above, however, unless the
managing underwriter of an offering described in Section 5.3 delivers a
written opinion to Trico that the inclusion of shares in such offering by the
Purchaser Group would have an effect such that the success of the offering
would be materially and adversely affected, in all cases, the Purchaser Group
collectively shall have the right to include Registrable Securities in any
registration under Section 5.3 in an aggregate amount equal to at least twenty
percent (20%) of the shares of Common Stock being sold.

  Section 5.5 Filings; Information. Whenever the Purchaser Representative
requests that any Registrable Securities be registered pursuant to Section 5.1
hereof, Trico will use its reasonable best efforts to effect the registration
of such Registrable Securities as promptly as is practicable, and in
connection with any such request:

  (a) Trico will as expeditiously as possible (1) prepare and file with the
SEC a Registration Statement on any form for which Trico then qualifies and
which counsel for Trico shall deem appropriate and available for the sale of
the Registrable Securities to be registered thereunder in accordance with the
intended method of distribution thereof, and use its reasonable best efforts
to cause such Registration Statement to become and remain effective, and (2)
prepare and file with the SEC such amendments and supplements to such
Registration Statement and the Prospectus used in connection with such
Registration Statement as may be necessary to keep such Registration Statement
effective in order to dispose of the shares registered thereunder in the
manner described in the underwriting agreement executed in connection
therewith and to comply with the provisions of the Securities Act with respect
to the disposition of all securities covered by such Registration Statement;
provided, however, that Trico shall have no obligation to maintain the
effectiveness of any registration statement filed hereunder or to cause the
information therein to remain current (A) for more than 90 days following such
Registration Statement's effective date in the case of a best efforts
underwritten public offering or (B) for longer than such period as is
customary and is required by the underwriter in the case of a firmly
underwritten public offering; and further provided that if Trico shall furnish
to the Purchaser Representative a certificate signed by a majority of the
Board stating that in their good faith judgment it would be detrimental or
otherwise disadvantageous to Trico or its stockholders for such a registration
statement to be filed as expeditiously as possible, Trico shall have a period
of not more than 90 days within which to file such registration statement
measured from the date of Trico's receipt of the Purchaser Representative's
request for registration in accordance with Section 5.1 hereof.

  (b) Trico will, if requested, prior to filing a Registration Statement or
any amendment or supplement thereto, furnish to the Participating Purchaser
and each applicable managing underwriter, if any, copies thereof, and
thereafter furnish to the Participating Purchasers and each such underwriter,
if any, such number of copies of

                                      B-7
<PAGE>

such Registration Statement, amendment and supplement thereto (in each case
including all exhibits thereto and documents incorporated by reference
therein) and the Prospectus included in such Registration Statement (including
each preliminary Prospectus) as the Participating Purchasers or each such
underwriter may reasonably request in order to facilitate the sale of the
Registrable Securities.

  (c) After the filing of the Registration Statement, Trico will promptly
notify the Participating Purchasers of any stop order issued or, to Trico's
knowledge, threatened to be issued by the SEC and take all reasonable actions
required to prevent the entry of such stop order or to remove it if entered.

  (d) Trico will use its reasonable best efforts to qualify the Registrable
Securities for offer and sale under such other securities or blue sky laws of
such jurisdictions in the United States as the Purchaser Representative
reasonably requests; provided that Trico will not be required to (1) qualify
generally to do business in any jurisdiction where it would not otherwise be
required to qualify but for this subsection 5.5(d); (2) subject itself to
taxation in any such jurisdiction; or (3) consent to general service of
process in any such jurisdiction.

  (e) Trico will as promptly as is practicable notify the Participating
Purchasers, at any time when a Prospectus is required by law to be delivered
in connection with sales by an underwriter or dealer, of the occurrence of any
event requiring the preparation of a supplement or amendment to such
Prospectus so that, as thereafter delivered to the purchasers of such
Registrable Securities, such Prospectus will not contain an untrue statement
of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading and promptly make
available to the Participating Purchasers and to the underwriters any such
supplement or amendment. The Purchasers agree that, upon receipt of any notice
from Trico of the occurrence of any event of the kind described in the
preceding sentence, the Purchasers will, and the Purchasers shall require any
other Participating Purchaser to, forthwith discontinue the offer and sale of
Registrable Securities pursuant to the Registration Statement covering such
Registrable Securities until receipt by the Participating Purchasers and the
underwriters of the copies of such supplemented or amended Prospectus and, if
so directed by Trico, the Participating Purchasers will deliver to Trico all
copies, other than permanent file copies, then in the Participating
Purchasers' possession of the most recent Prospectus covering such Registrable
Securities at the time of receipt of such notice. In the event Trico shall
give such notice, Trico shall extend the period during which such Registration
Statement shall be maintained effective as provided in Section 5.5(a) by the
number of days during the period from and including the date of the giving of
such notice to the date when Trico shall make available to the Participating
Purchasers such supplemented or amended Prospectus.

  (f) Trico will enter into customary agreements (including an underwriting
agreement in customary form) and take such other actions as are reasonably
required in order to expedite or facilitate the sale of such Registrable
Securities.

  (g) Trico will furnish to the Participating Purchasers and to each
underwriter a signed counterpart, addressed to the Participating Purchasers or
such underwriter, of an opinion or opinions of counsel to Trico and a comfort
letter or comfort letters from Trico's independent public accountants, each in
customary form and covering such matters of the type customarily covered by
opinions or comfort letters, as the case may be, as the Purchaser
Representative or the managing underwriter reasonably requests.

  (h) Trico will make generally available to its security holders, as soon as
reasonably practicable, an earnings statement covering a period of 12 months,
beginning within three months after the effective date of the Registration
Statement, which earnings statement shall satisfy the provisions of Section
11(a) of the Securities Act and the rules and regulations of the SEC
thereunder.

  (i) Trico will use its reasonable best efforts to cause all such Registrable
Securities to be listed on each securities exchange or market on which the
Common Stock is then listed.

                                      B-8
<PAGE>

  (j) Trico may require the Participating Purchasers to furnish promptly in
writing to Trico such information regarding such members, the plan of
distribution of the Registrable Securities and other information as Trico may
from time to time reasonably request or as may be legally required in
connection with such registration.

  Section 5.6 Registration Expenses. In connection with any Demand
Registration, any Piggyback Registration and any Shelf Registration, Trico
shall pay the following expenses incurred in connection with such
registration: (a) filing fees with the SEC; (b) fees and expenses of
compliance with securities or blue sky laws (including reasonable fees and
disbursements of counsel in connection with blue sky qualifications of the
Registrable Securities); (c) printing expenses; (d) fees and expenses incurred
in connection with the listing of the Registrable Securities; (e) fees and
expenses of counsel and independent certified public accountants for Trico and
(f) the reasonable fees and expenses of any additional experts retained by
Trico in connection with such registration. In connection with the preparation
and filing of a Registration Statement pursuant to Section 5.1, Trico will
also pay the reasonable fees and expenses of a single legal counsel chosen by
the Purchaser Representative. The Participating Purchasers shall pay any
underwriting fees, discounts or commissions attributable to the sale of
Registrable Securities and any other expenses of the Participating Purchasers.

  Section 5.7 Participation in Underwritten Registrations. No Person may
participate in any underwritten registered offering contemplated hereunder
unless such Person (a) agrees to sell its securities on the basis provided in
any underwriting arrangements approved by the Persons entitled hereunder to
approve such arrangements and (b) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
reasonably required under the terms of such underwriting arrangements and this
Agreement.

  Section 5.8 Holdback Agreements. The Purchasers agree not to, and that no
other Participating Purchaser will, offer, sell, contract to sell or otherwise
dispose of any Registrable Securities, or any securities convertible into or
exchangeable or exercisable for such securities, during the 14 days prior to,
and during the 90-day period beginning on, the effective date of such
registration statement other than the Registrable Securities to be sold
pursuant to such registration statement.

  Section 5.9 Indemnification by Trico. Trico agrees to indemnify and hold
harmless the Participating Purchasers, their general partner and their
officers and directors, and each Person, if any, who controls such
Participating Purchasers within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act from and against any and all
losses, claims, damages and liabilities caused by any untrue statement or
alleged untrue statement of a material fact contained in any Registration
Statement or Prospectus relating to the Registrable Securities or any
preliminary Prospectus or any amendment or supplement to such Registration
Statement, or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the
statements therein not misleading; and Trico will reimburse such Participating
Purchasers, general partners, officers, directors, and each such controlling
Person for any legal or any other expenses reasonably incurred by such
Participating Purchasers, general partners, officers, directors, or
controlling Persons in connection with investigating or defending any such
loss, claim, damage, liability or action; provided, however, that Trico will
not be liable in any such case to the extent that any such loss, claim, damage
or liability arises out of or is based upon any untrue statement or omission
made in such Registration Statement, preliminary Prospectus or Prospectus, or
any such amendment or supplement, in reliance upon and in conformity with
written information furnished to Trico through an instrument duly executed by
or on behalf of such Participating Purchasers specifically for use in
preparation thereof. Trico also agrees to indemnify any underwriters of the
Registrable Securities, their officers and directors and each Person who
controls such underwriters on substantially the same basis as that of the
indemnification of the Participating Purchasers provided in this Section 5.9.

  Section 5.10 Indemnification by The Purchasers. The Purchasers agree to, and
that the other Participating Purchasers will, indemnify and hold harmless
Trico, its officers and directors, and each Person, if any, who controls Trico
within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act to the same extent as the foregoing indemnity from Trico to
the Participating Purchasers, but only with reference

                                      B-9
<PAGE>

to information relating to the Participating Purchasers furnished in writing
by or on behalf of the Participating Purchasers expressly for use in any
Registration Statement or Prospectus, or any amendment or supplement thereto,
or any preliminary Prospectus. The Purchasers also agree to, and that the
other Participating Purchasers will, indemnify and hold harmless any
underwriters of the Registrable Securities, their officers and directors and
each person who controls such underwriters on substantially the same basis as
that of the indemnification of Trico provided in this Section 5.10.

  Section 5.11 Conduct of Indemnification Proceedings. In case any proceeding
(including any governmental investigation) shall be instituted involving any
Person in respect of which indemnity may be sought pursuant to Section 5.9 or
Section 5.10, such Person (the "Indemnified Party") shall promptly notify the
Person against whom such indemnity may be sought (the "Indemnifying Party") in
writing and the Indemnifying Party shall have the right to assume the defense
of such proceeding and retain counsel reasonably satisfactory to such
Indemnified Party to represent such Indemnified Party and any others the
Indemnifying Party may designate in such proceeding and shall pay the fees and
disbursements of such counsel related to such proceeding. In any such
proceeding, any Indemnified Party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Party unless (a) the Indemnifying Party and the Indemnified
Party shall have mutually agreed to the retention of such counsel or (b) the
named parties to any such proceeding (including any impleaded parties) include
both the Indemnified Party and the Indemnifying Party and representation of
both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. It is understood that the
Indemnifying Party shall not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the fees and expenses of
more than one separate firm of attorneys (in addition to any local counsel) at
any time for all such Indemnified Parties, and that all such fees and expenses
shall be reimbursed as they are incurred. In the case of any such separate
firm for the Indemnified Parties, such firm shall be designated in writing by
the Indemnified Parties. The Indemnifying Party shall not be liable for any
settlement of any proceeding effected without its written consent, but if
settled with such consent, or if there be a final judgment for the plaintiff,
the Indemnifying Party shall indemnify and hold harmless such Indemnified
Parties from and against any loss or liability (to the extent stated above) by
reason of such settlement or judgment.

  Section 5.12 Rule 144. Trico covenants that it will file any reports
required to be filed by it under the Securities Act and the Exchange Act and
that it will take such further action as the Purchaser Representative may
reasonably request to the extent required from time to time to enable the
Purchaser Group to sell Registrable Securities without registration under the
Securities Act within the limitation of the exemptions provided by Rule 144
under the Securities Act, as such Rule may be amended from time to time, or
any similar rule or regulation hereafter adopted by the SEC. Upon the request
of the Purchaser Representative, Trico will deliver to the Purchaser Group a
written statement as to whether it has complied with such reporting
requirements, a copy of the most recent annual or quarterly report of Trico,
and such other reports and documents so filed by Trico as may be reasonably
requested in availing the Purchaser Group of any rule or regulation of the SEC
permitting the selling of any such Registrable Securities without
registration.

  Section 5.13 Future Grants of Registration Rights. From and after the date
of this Agreement, Trico shall not enter into any agreement with any holder or
prospective holder of any Trico Securities that provides for the granting to
such holder of registration rights unless such agreement is subject and
subordinate to the rights of the Purchaser Group hereunder or unless Trico
first obtains from the Purchaser Representative its consent to the terms
thereof.

  Section 5.14 Transfer of Registration Rights. The registration rights of the
Purchaser Group under this Agreement may be assigned and transferred to any
transferee purchasing Registrable Securities, other than in a public offering
pursuant to a Registration Statement, in an amount equal to at least 100,000
Registrable Securities; provided, however, that the Company is given written
notice by the Purchaser Group at the time of such transfer stating the name
and address of the transferee and identifying the Registrable Securities with
respect to which the rights under this Agreement are being assigned. This
Agreement shall also be binding upon and enforceable by the heirs, executors,
or other personal representatives of the Purchasers and the successors and
assigns of Trico.

                                 Miscellaneous

  Section 6.1 Termination. Except as provided in this Section 6.1, the
respective covenants and agreements of the Purchasers and Trico contained in
this Agreement will continue in full force and effect until the Termination
Date; provided, however, that Trico shall have no further obligation to the
Purchaser Group to file a Registration Statement or to effect a registration
of Registrable Securities pursuant to Sections 5.1, 5.2 and 5.3 after the sale
or other disposition in accordance with this Agreement by the Purchaser Group
of such number of Trico Securities such that the Purchaser Group beneficially
own, in the aggregate, Trico Securities representing less than 10% of the
shares of Common Stock purchased thereby pursuant to the Purchase Agreement.
Upon any termination of this Agreement pursuant to this Section 6.1 all of the
obligations of Trico and the Purchasers hereunder shall terminate.

  Section 6.2 Recovery of Fees. Except as otherwise described herein, any
party who shall obtain a final judgment in a court of competent jurisdiction
for the payment of damages by another party for a breach of this Agreement
shall be entitled to recover reasonable attorneys' fees and court costs
incurred in connection with the obtaining of such judgment.

  Section 6.3 Notices. Any notice or other communication required or permitted
hereunder shall be in writing or by telex, telephone or facsimile transmission
with subsequent written confirmation, and may be personally served or sent by
United States mail and shall be deemed to have been given upon receipt by the
party notified. For purposes hereof, the addresses of the parties hereto
(until notice of a change thereof is delivered as provided in this Section 6
shall be as set forth opposite each party's name on the signature page hereof.

  Section 6.4 Waivers and Amendments; Noncontractual Remedies; Preservation of
Remedies. This Agreement may be amended, superseded, canceled, renewed or
extended, and the terms hereof may be waived, only by a written instrument
signed by Trico and the Purchaser Representative or, in the case of a waiver,
by the party waiving compliance. No delay on the part of any party in
exercising a right, power or privilege hereunder shall operate as a waiver
thereof, nor shall any waiver on the part of any party of any such right,
power or privilege, nor any single or partial exercise of any such right,
power or privilege, preclude a further exercise thereof or the exercise of any
other such right, power or privilege. The rights and remedies herein provided
are cumulative and are not exclusive of any rights or remedies that any party
may otherwise have at law or in equity. The rights and remedies of any party
based upon, arising out of or otherwise in respect of any breach of any
provision of this Agreement shall in no way be limited by the fact that the
act, omission, occurrence or other state of facts upon which any claim of any
such breach is based may also be the subject matter of any other provision of
this Agreement (or of any other agreement between the parties) as to which
there is no breach.

  Section 6.5 Specific Performance. The parties recognize that in the event
Trico or the Purchaser Group should refuse to perform under the provisions of
this Agreement, monetary damages alone will not be adequate. The Purchaser
Group or Trico, as the case may be, shall therefore be entitled, in addition
to any other remedies which may be available, including money damages, to
obtain specific performance of the terms of this Agreement, without any
requirement for the posting of any bond. In the event of any action to enforce
this Agreement specifically, Trico and the Purchaser Group hereby waive the
defense that there is an adequate remedy at law.

  Section 6.6 Severability. If any provision of this Agreement or the
applicability of any such provision to a person or circumstances shall be
determined by any court of competent jurisdiction to be invalid or
unenforceable to any extent, the remainder of this Agreement or the
application of such provision to persons or circumstances other than those for
which it is so determined to be invalid and unenforceable, shall not be
affected thereby, and each provision of this Agreement shall be valid and
shall be enforced to the fullest extent permitted by law. To the extent
permitted by applicable law each party hereto hereby waives any provision or
provisions of law which would otherwise render any provision of this Agreement
invalid, illegal or unenforceable in any respect.

  Section 6.7 Counterparts. This Agreement may be executed by the parties
hereto in separate counterparts and when so executed shall constitute one
Agreement, notwithstanding that all parties are not signatories to the same
counterpart.

  Section 6.8 Governing Law. This Agreement shall be governed and construed in
accordance with the laws of the State of Delaware applicable to agreements
made and to be performed entirely within such state.

  Section 6.9 Successors and Assigns. Subject to Section 6, this Agreement
shall be binding upon and inure to the benefit of and be enforceable by the
successors and assigns of the parties hereto.
