                              OVERHILL FARMS, INC.

                              AMENDED AND RESTATED
                            INVESTOR RIGHTS AGREEMENT

     THIS AMENDED AND RESTATED INVESTOR RIGHTS AGREEMENT is entered into as of
the ____ day of _________ 2002 (this "Agreement"), by and among OVERHILL FARMS,
INC., a Nevada corporation (the "Company"), JAMES RUDIS, an individual
("Rudis"), WILLIAM E. SHATLEY, an individual ("Shatley"), and LEVINE LEICHTMAN
CAPITAL PARTNERS II, L.P., a California limited partnership ("LLCP"). Rudis and
Shatley are referred to herein individually as a "Principal Shareholder" and
collectively as the "Principal Shareholders."

                                 R E C I T A L S

     A.   The Company, OVERHILL CORPORATION (formerly known as Polyphase
Corporation and to be known from and after the effective date of the Spin-Off as
TreeCon Resources, Inc.), a Nevada corporation ("Parent"), Overhill Ventures and
LLCP entered into that certain Securities Purchase Agreement dated as of
November 24, 1999, as amended by that certain Consent and First Amendment to
Securities Purchase Agreement dated as of August 23, 2000, and as further
amended by that certain Second Amendment to Securities Purchase Agreement dated
as of January 11, 2002, that certain Consent and Third Amendment dated as of
January 31, 2002, that certain Fourth Amendment dated as of June 28, 2002, and
that certain Fifth Amendment to Securities Purchase Agreement dated as of
September 11, 2002 (as so amended, the "Original Securities Purchase
Agreement").

     B.   In connection with the execution and delivery of the Original
Securities Purchase Agreement, the Company, Parent and LLCP entered into that
certain Investor Rights Agreement dated as of November 24, 1999, as amended by
an Amendment to Investor Rights Agreement dated as of August 25, 2000, and as
further amended by a Second Amendment to Investor Rights Agreement dated as of
January 11, 2002 (as so amended, the "Original Investor Rights Agreement"),
pursuant to which, among other things, the Company and Parent granted to LLCP
certain investment monitoring and other rights all as described therein.

     C.   The Board of Directors of Parent has previously approved a plan to
distribute to its stockholders on a pro rata basis in the form of a stock
dividend the shares of Common Stock owned or held by Parent and thereby "spin
off" the Company as a separate, independent publicly traded company (the
"Spin-Off"). Immediately following the Spin-Off, Parent will not beneficially
own or hold any shares of, or any Option Rights with respect to, the Capital
Stock of the Company.

     D.   The Company, the entities from time to time parties thereto as
Guarantors and LLCP are concurrently entering into that certain Amended and
Restated Securities Purchase Agreement dated of even date herewith (as amended
from time to time, the "Securities Purchase Agreement") pursuant to which, among
other things, (a) the parties

<PAGE>

thereto are amending and restating the Original Securities Purchase Agreement,
the Original Note and the Original Warrant and (b) at the request of the
Company, LLCP is consenting to the Spin-Off Related Matters, all on the terms
and subject to the conditions set forth therein. Unless otherwise indicated, all
capitalized terms used and not otherwise defined herein have the meanings
ascribed to them in the Securities Purchase Agreement or the Original Investor
Rights Agreement, as the case may be.

     E.   Rudis is the current President and Chief Executive Officer of the
Company and Shatley is a Senior Vice President of the Company. Immediately
following the Spin-Off, Rudis will be the beneficial owner of _________ shares
of Common Stock, par value $0.01 per share, of the Company ("Common Stock"),
including options to purchase _____ shares of Common Stock issued under the 2002
Stock Option Plan, and Shatley will be the beneficial owner of _________ shares
of Common Stock, including options to purchase _____ shares of Common Stock
issued under the 2002 Stock Option Plan.

     F.   It is a condition precedent to the effectiveness of the Securities
Purchase Agreement, including the consent of LLCP to the Spin-Off Related
Matters, that the Company affirm, amend and restate the Original Investor Rights
Agreement on the terms and conditions contained herein, and the Principal
Shareholders become parties to this Agreement.

     G.   It is intended that the Spin-Off will not constitute a transaction
that would trigger LLCP's "co-sale" rights under Section 3 of the Original
Investor Rights Agreement, and that because Parent will not be liable for the
debts, liabilities or obligations of the Company or beneficially own or hold any
shares of Capital Stock of the Company from and after the date hereof, Parent
will no longer be a party to this Agreement from and after the date hereof.

                                A G R E E M E N T

     NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereby amend and
restate the Original Investor Rights Agreement as follows:

1.   INVESTMENT MONITORING RIGHTS.

     1.1  Election of LLCP Representative to Board.

          (a)  LLCP shall have the right, exercisable from time to time, to
     require the Company to cause to be nominated and elected or appointed to
     the Board of Directors of the Company (the "Board") an individual
     designated by LLCP in an LLCP Representative Request (as such term is
     defined below) (the "LLCP Representative") furnished by LLCP to the Company
     and each Principal Shareholder. If LLCP wishes to have an individual
     elected or appointed as a member of the Board, LLCP shall deliver to the
     Company, with a copy to each Principal Shareholder, a written request (an
     "LLCP Representative Request") notifying the Company of LLCP's election
     under this Section 1.1 to have an LLCP

                                      -2-

<PAGE>

     Representative nominated and elected or appointed to the Board and
     designating the individual to be so nominated, elected or appointed.

          (b)  Within five (5) Business Days after the Company receives an LLCP
     Representative Request, the Company shall take (or cause to be taken) as
     soon as practicable any and all actions as may be necessary or advisable to
     cause the LLCP Representative to be nominated and elected or appointed to
     the Board and to remain a duly elected or appointed member of the Board
     (including, among other actions, nominating the LLCP Representative to be a
     member of the Board, creating a vacancy for the LLCP Representative or
     increasing the size of the Board and filling the resulting vacancy with the
     LLCP Representative, as applicable).

          (c)  Removal. No individual serving as the LLCP Representative may be
     removed from the Board without the prior written approval of LLCP other
     than for "cause." For purposes of this Section 1.1(c), the term "cause"
     shall mean a conviction (treating a nolo contendere plea or a guilty plea
     as a conviction) of a felony or of a crime of moral turpitude. If any LLCP
     Representative shall be removed from the Board for cause, then LLCP shall
     have the sole right to designate another individual to serve as the LLCP
     Representative, and the Company shall, upon the request of LLCP, promptly
     (and in any event within five (5) Business Days of such request) take any
     and all actions as may be necessary or appropriate to cause such other
     individual to be nominated and elected or appointed to the Board as the
     LLCP Representative.

          (d)  Vacancy. In the event of the death or resignation, or removal by
     LLCP, of the LLCP Representative at any time, or in the event the LLCP
     Representative shall not be elected to the Board for any reason, the
     Company shall, upon the request of LLCP, promptly (and in any event within
     five (5) Business Days of such request) take any and all actions as may be
     necessary or appropriate to cause another individual designated by LLCP to
     be nominated and elected or appointed to the Board as the LLCP
     Representative. Such actions may include, but not be limited to, calling
     and/or holding, in accordance with the Bylaws of the Company and Applicable
     Laws, a special meeting of the Board or obtaining the written consent of
     all members of the Board or, if possible, the shareholders holding at least
     the requisite number of shares necessary to elect or appoint such
     individual as a member of the Board, as the case may be.

          (e)  Committees. To the extent that the Board delegates any of its
     duties to any committee(s) of the Board, the LLCP Representative shall,
     upon the request of LLCP, be appointed to such committee(s).

     1.2  Agreement to Vote.

          (a)  The Principal Shareholders each agree to hold all of his
     Principal Shareholder Shares subject to, and to vote the Principal
     Shareholder Shares in accordance with, the provisions of this Agreement.
     The term "Principal Shareholder Shares" shall mean, with respect to any
     Principal Shareholder, any and all Capital Stock and other voting
     securities of the Company beneficially owned or

                                      -3-

<PAGE>

     held by him, or registered in his name, on the date hereof, and any and all
     Capital Stock and other voting securities of the Company owned or held by
     him, or registered in his name, after the date hereof, and any securities
     of the Company issued with respect to, upon conversion of, or in exchange
     or substitution for, such securities.

          (b)  On all matters relating to the election or appointment of members
     of the Board, each Principal Shareholder agrees, on behalf of himself and
     any transferee or assignee of Principal Shareholder Shares, to vote all of
     his Principal Shareholder Shares (or to consent pursuant to any action by
     written consent) in favor of electing or appointing the LLCP Representative
     to the Board.

          (c)  Enforceable Voting Agreement. The agreements set forth in this
     Section 1.2 are intended to constitute enforceable voting agreements within
     the scope of Section 706(a) of the General Corporation Law of the State of
     California.

     1.3  Observation Rights. In addition to the rights granted to LLCP in this
Section 1.1, if, at any time, no LLCP Representative is serving on the Board for
any reason, LLCP shall be entitled to receive written notice of, and to have one
(1) representative and one (1) advisor to such representative (or, at LLCP's
election, two (2) representatives) attend as observers at, all meetings of the
Board (and of all committees thereof) and all meetings of the shareholders of
the Company. Written notice of all such meetings shall be given to LLCP in the
same manner and at the same time, to the extent permitted by Applicable Laws, as
to the members of the Board or such committees (which in any event shall not be
less than forty-eight (48) hours prior to such meeting unless otherwise agreed
to by LLCP in advance and in writing) and at the same time as to the
shareholders of the Company, as the case may be. The Company shall furnish LLCP
with copies of (i) the meeting agenda, if any is prepared, (ii) all information
that is furnished to the members of the Board (or such committees) or to the
shareholders of the Company (whether prior to, at, or subsequent to any such
meetings), as the case may be, at the same time as such materials are furnished
to the members of the Board or such committee or to the shareholders of the
Company, as the case may be, and (iii) copies of the minutes of all meetings of
the Board (and such committees) and of all meetings of shareholders concurrently
with the distribution of such minutes to one or more members of the Board (or
such committees) or shareholders, as the case may be, but in no event later than
forty-five (45) days after each such meeting.

     1.4  Operating Committee.

          (a)  Under the Original Investor Rights Agreement, the Company
     established for the benefit of LLCP an operating committee (the "Operating
     Committee") to, among other things, (i) review the annual operating and
     capital budget of the Company and its Subsidiaries; (ii) compare budgeted
     versus actual performance of the Company and its Subsidiaries; (iii)
     analyze working capital management; and (iv) review the cash flow
     performance of the Company and its Subsidiaries. The Operating Committee
     shall also consider such additional financial matters as it shall deem
     advisable. The Operating Committee shall not constitute a committee
     designated by the Board pursuant to the Company's Bylaws or NRS 78.125, and
     shall not have any authority to act in the name of or on behalf of

                                      -4-

<PAGE>

     the Company or any of its Subsidiaries, but the Operating Committee shall
     have the right to make suggestions and to recommend actions to the Board or
     to the Board of Directors of any Subsidiary of the Company or to any
     committee of any such Board of Directors, either in writing or by
     attending, through a representative, a meeting of such Board of Directors
     or such committee.

          (b)  The Operating Committee shall at all times be comprised of at
     least two (2) members of senior management of the Company, who initially
     shall be James Rudis, the current President and Chief Executive Officer of
     the Company, and Richard A. Horvath, the current Chief Financial Officer of
     the Company, and two (2) members designated by LLCP (who shall be
     representatives of Levine Leichtman Capital Partners, Inc. ("LLCP Inc."),
     an Affiliate of LLCP). The financial officers and other members of senior
     management of the Company shall be available, in person or by telephone, at
     each meeting of the Operating Committee to review financial information and
     discuss other matters.

          (c)  Regular meetings of the Operating Committee shall take place on
     or about the third Tuesday of each calendar month, unless otherwise agreed.
     Meetings may be conducted by telephone so long as each of the persons
     attending can hear each of the other persons attending the meeting. The
     Company's financial officers shall prepare a financial package for delivery
     to all Operating Committee members at least forty-eight (48) hours prior to
     each regularly scheduled monthly meeting. The financial package shall
     include, among other things, (i) a consolidated and consolidating balance
     sheet, statement of operations and statement of cash flows of the Company
     and its Subsidiaries for the most recent one-month period and for the
     year-to-date period, (ii) a comparison of the actual results of operations
     for such periods to the same periods in the prior year and to the budget
     and forecast, (iii) an explanation of any variances in such actual results
     of operations from such budget and forecast, (iv) the status of any
     permitted dispositions of assets by the Company or its Subsidiaries, (v) an
     update of the status of all litigation or similar proceedings pending
     against the Company or any of its officers, directors, Subsidiaries or
     other Affiliates and (vii) such other information regarding the Company or
     its Subsidiaries as any member of the Operating Committee may from time to
     time request.

     1.5  [Intentionally Omitted]

     1.6  Consulting Fees.

          (a)  In consideration of consulting services rendered and which may be
     rendered by LLCP or LLCP Inc. to the Company under this Section 1
     (including in connection with the exercise of the observation and other
     rights granted under Section 1.3 or during any Operating Committee
     meetings) during the five (5) twelve-month periods immediately following
     the Initial Closing Date, which services are hereby acknowledged by the
     Company as being substantial and valuable to its business and operations,
     the Company agrees to pay to LLCP Inc. a consulting fee in the aggregate
     amount of $900,000. The Company agrees that the full amount of such
     consulting fee shall be fully earned as of the Initial Closing Date
     (whether or not the Note remains outstanding at all times during the entire
     five (5) twelve-month

                                      -5-

<PAGE>

     period), but that such consulting fee shall be payable in five (5) equal
     installments of $180,000 each and shall be due on the following dates:
     January 10, 2000, January 10, 2001, January 10, 2002, January 10, 2003 and
     January 10, 2004; provided, however, that upon the earlier to occur of (i)
     a Change in Control and (ii) the date upon which all Obligations under the
     Note shall have been paid in cash in full, the portion of the consulting
     fee remaining unpaid shall at such time become immediately due and payable
     to LLCP Inc.

          (b)  [Intentionally Omitted.]

          (c)  The consulting fees payable to LLCP Inc. under this Section 1.6
     shall be paid by wire transfer in immediately available funds to a bank
     account designated by LLCP Inc. In no event shall LLCP Inc. be obligated to
     refund or waive its receipt of all or any portion of the consulting fees
     payable to it hereunder for any reason.

          (d)  In addition, the Company agrees to pay to LLCP Inc. a
     non-refundable monthly consulting fee in the amount of $12,000 for each
     calendar month (or portion thereof) during the period commencing on
     February 1, 2002, and ending on the date upon which all Obligations under
     the Note have been paid in cash in full. Each monthly consulting fee shall
     be due and payable in advance on the first Business Day of each such
     calendar month.

     1.7  Survival of Rights. The rights granted to LLCP under Section 1.1
(Agreement to Vote) and Section 1.3 (Observation Rights) became effective as of
the Initial Closing Date and shall continue for so long as LLCP continues to
hold, directly or indirectly, at least $2,500,000 in outstanding principal
amount of the Note, or at least five percent (5.0%) of the shares of Common
Stock calculated on a Fully Diluted Basis. The rights granted to LLCP under
Section 1.4 (Operating Committee) became effective as of the Initial Closing
Date and shall continue for so long as any principal amount of the Note remains
outstanding. Notwithstanding anything to the contrary contained herein or
otherwise, the rights granted to LLCP under Section 1.1 (Agreement to Vote),
Section 1.3 (Observation Rights) and Section 1.4 (Operating Committee) shall
survive to the extent that LLCP holds the Note or any Warrant Shares and informs
the Company in writing that it believes in good faith that it is required to
retain such rights to qualify as a "venture capital operating company" for
purposes of complying with ERISA.

2.   INDEMNIFICATION AND INSURANCE.

     2.1  The Company shall, to the maximum extent permitted by Applicable Law,
indemnify, defend and hold harmless the LLCP Representative, any LLCP
representatives participating in the Operating Committee, LLCP and the
employees, partners, principals, agents, attorneys, accountants, representatives
and Affiliates of LLCP (including LLCP Inc.) (individually, an "LLCP Party" and,
collectively, the "LLCP Parties"), from and against all costs, expenses,
liabilities, claims, judgments, damages and losses, including all attorneys'
fees and the cost of preparation and investigation, incurred in connection with
any threatened, pending or completed action or proceeding, whether civil,
criminal, administrative or investigative (collectively, "Liabilities and
Costs"), arising out of or in any way related to the fact that any LLCP Party is
or was a director, officer, employee or

                                      -6-

<PAGE>

other agent of the Company or any subsidiary of the Company, is or was serving
on the Operating Committee, is or was serving as an observer of the Board, or is
or was serving at the request of the Company as a director, officer, employee,
trustee, agent or fiduciary of another corporation, partnership, joint venture,
employee benefit plan, trust or other enterprise.

     2.2  Upon request by any LLCP Party, the Company shall advance (within five
(5) Business Days of such request) any and all expenses, including any and all
attorneys' fees and the cost of any investigation and preparation incurred in
connection with any matter for which such LLCP Party is or may be entitled to
indemnification hereunder; provided, however, that if and to the extent that a
court of competent jurisdiction finally determines that such LLCP Party is not
permitted to be indemnified with respect to such matter under Applicable Law,
the Company shall be entitled to be reimbursed for any expenses so advanced. The
Company shall also indemnify each LLCP Party from and against any and all
Liabilities and Costs incurred in connection with any claim or action brought to
enforce such LLCP Party's rights under this Section 2, or under Applicable Law
or the Company's charter or bylaws now or hereafter in effect relating to
indemnification, or for recovery under directors' and officers' liability
insurance policies maintained by the Company, regardless of whether such LLCP
Party is ultimately determined to be entitled to such indemnification or
insurance recovery, as the case may be. If, for any reason, the foregoing
indemnification is not available for any reason or is not sufficient to
indemnify and hold the LLCP Parties harmless from all such Liabilities and
Costs, the Company shall contribute to the amount of all such Liabilities and
Costs paid or payable by any LLCP Party in such proportion as is appropriate to
reflect not only the relative benefits received by the Company, on the one hand,
and LLCP, on the other hand, but also the relative fault of each, as well as any
other equitable considerations. The Company's reimbursement, indemnity and
contribution obligations shall be in addition to any liability the Company may
otherwise have at law or under any other agreement, including the Securities
Purchase Agreement, and such obligations shall extend, upon the same terms, to
all LLCP Parties. This Section 2 shall survive the termination of this Agreement
indefinitely.

     2.3  During the term of this Agreement, the Company shall maintain in force
and effect one or more policies of insurance covering directors and officers
liability in an insured amount of not less than $10,000,000. Such insurance
policies shall cover, among other things, claims asserted under federal and
state securities laws and such other matters as are customary and appropriate
for publicly traded companies operating in the Company's industry.

3.   CO-SALE AGREEMENT.

     3.1  If any Principal Shareholder (a "Selling Principal Shareholder")
proposes to sell or transfer (a "sale") any Principal Shareholder Shares
("Co-Sale Shares") to a bona fide purchaser or transferee (a "purchaser") in one
(1) transaction or any series of related transactions, such Principal
Shareholder shall promptly give written notice (the "Co-Sale Notice") to the
Company and to LLCP at least thirty (30) days prior to the closing of such sale.
The Co-Sale Notice shall describe in reasonable detail the terms of the proposed
sale, including the number of Co-Sale Shares to be sold, the nature of the sale,
the amount of consideration to be paid and the name and address of the proposed
purchaser.

                                      -7-

<PAGE>

Notwithstanding the foregoing, without complying with the procedures of this
Section 3, (a) Rudis may sell up to an aggregate of 50,000 Principal Shareholder
Shares in open market transactions (not in a private sale transaction) during
any Fiscal Year of the Company, it being understood that a Change in Control
shall occur if Rudis ceases to beneficially own or hold less than 300,000 shares
of Common Stock at any time, (b) Shatley may sell up to an aggregate of 50,000
shares in open market transactions (not in a private sale transaction) during
any Fiscal Year of the Company, it being understood that a Change in Control
shall occur if Shatley ceases to beneficially own or hold less than 150,000
shares of Common Stock at any time and (c) any Principal Shareholder may
transfer his Principal Shareholder Shares to his spouse or descendants or to
trusts or family partnerships established for the benefit of himself or such
persons, provided that such Principal Shareholder provides to LLCP at least
thirty (30) days prior written notice of such transfer and the transferee
executes a joinder agreement, in form and substance satisfactory to LLCP,
pursuant to which such transfer becomes bound by, and agrees to comply with, the
provisions of this Agreement as if such transferee were a Principal Shareholder.

     3.2  LLCP shall have the right, exercisable by furnishing written notice to
the Selling Principal Shareholder within twenty (20) days after its receipt of
the Co-Sale Notice, to participate in such sale on the same terms and conditions
as specified in the Co-Sale Notice. To the extent that LLCP exercises such right
of participation in accordance with the terms set forth in this Section 3, the
number of Co-Sale Shares that the Selling Principal Shareholder may sell in the
transaction(s) shall be proportionately reduced.

     3.3  If there shall be a decrease in the price to be paid by the proposed
purchaser for the Co-Sale Shares from the price set forth in the Co-Sale Notice,
which decrease is acceptable to the Selling Principal Shareholder, or there is
any other material change to the terms or conditions set forth in the Co-Sale
Notice which is less favorable to the Selling Principal Shareholder but which is
acceptable to him, the Selling Principal Shareholder shall immediately notify
LLCP in writing of such decrease or other change. LLCP shall have the right to
participate in such sale on such modified terms by furnishing written notice to
the Selling Principal Shareholder within (a) if LLCP has not yet delivered a
notice to the Principal Shareholder pursuant to Section 3.2, the greater of (i)
the remaining number of days in the twenty (20) day period set forth in Section
3.2 and (ii) ten (10) Business Days from the date of its receipt of such written
notice, or (b) if LLCP has delivered a written notice to the Selling Principal
Shareholder pursuant to Section 3.2, ten (10) Business Days from the date of its
receipt of such written notice to modify the terms set forth in the written
notice it previously furnished to the Selling Principal Shareholder.

     3.4  LLCP may sell at the time of sale all or any portion of that number of
shares of Capital Stock of the Company beneficially owned or held by it equal to
the product of (a) the aggregate number of Co-Sale Shares covered by the Co-Sale
Notice, multiplied by (ii) a fraction, the numerator of which is the total
number of shares of Common Stock beneficially owned, directly or indirectly, by
LLCP at the time of sale (including the Warrant Shares and the shares of Common
Stock issued or issuable upon exercise or conversion of any Option Rights of the
Company (including the Series A Preferred Shares) beneficially owned, directly
or indirectly, by LLCP) (collectively, the "LLCP Shares"), and the denominator
of which is the sum of the total number of shares of Common Stock beneficially
owned by the Selling Principal Shareholder and the total number of LLCP

                                      -8-

<PAGE>

Shares at the time of sale. In no event shall LLCP be required to make any
representation or warranty in connection with the sale to any purchaser other
than as to the organization and authority of LLCP, title to the LLCP Shares to
be sold and the absence of conflicts with organizational documents and material
agreements.

     3.5  LLCP shall effect its participation in the sale by promptly delivering
to the Selling Principal Shareholder at the closing of the sale of the Co-Sale
Shares, for transfer to the prospective purchaser, one or more certificates,
properly endorsed for transfer, which represent the type and number of shares of
Capital Stock of the Company which LLCP elects to sell.

     3.6  The Selling Principal Shareholder shall transfer the certificate or
certificates that LLCP delivers to the Selling Principal Shareholder pursuant to
Section 3.5 to the purchaser on the terms and conditions specified in the
Co-Sale Notice, and the Selling Principal Shareholder shall cause the purchaser
to remit to LLCP directly, concurrently with the closing and in immediately
available funds to an account designated by LLCP, that portion of the sale
proceeds to which LLCP is entitled by reason of LLCP's participation in the
sale. To the extent that any purchaser refuses to purchase shares or other
securities from LLCP, the Selling Principal Shareholder shall not sell to such
purchaser any shares of Capital Stock of the Company unless and until,
simultaneously with such sale, the Selling Principal Shareholder shall purchase
such shares or other securities from LLCP. Subject to the foregoing sentence, if
the Selling Principal Shareholder does not complete the proposed sale for any
reason, the Selling Principal Shareholder shall immediately return to LLCP all
documents (including all stock certificates, stock assignments and/or powers of
attorney) which LLCP delivered to the Selling Principal Shareholder pursuant to
this Section 3 or otherwise in connection with such sale.

     3.7  The exercise or non-exercise of the rights of LLCP hereunder to
participate in one or more sales of Co-Sale Shares by the Selling Principal
Shareholder shall not adversely affect its rights to participate in subsequent
sales of Co-Sale Shares by any Principal Shareholder.

     3.8  The provisions of Section 3 shall not apply to the sale of any Co-Sale
Shares (a) to the public pursuant to a registration statement filed with, and
declared effective by, the Commission under the Securities Act or (b) to the
Company.

     3.9  Prohibited Transfers.

          (a)  If any Principal Shareholder sells (or enters into any agreement,
     arrangement or understanding to sell) any Co-Sale Shares in violation or
     contravention of the co-sale rights of LLCP under this Section 3 (a
     "Prohibited Transfer"), LLCP shall have, in addition to all other rights,
     powers or remedies available at law, in equity, under this Agreement or any
     other Investment Document or under Applicable Law, the right to exercise
     such Prohibited Transfer Put (as such term is defined below) and, if so
     exercised, the Principal Shareholder shall be bound to perform its
     obligations under this Section 3.9.

                                      -9-

<PAGE>

          (b)  In the event of a Prohibited Transfer, LLCP shall have the right
     to sell to such Principal Shareholder, and such Principal Shareholder shall
     be obligated to purchase (the "Prohibited Transfer Put"), the type and
     number of shares of Capital Stock of the Company equal to the number of
     shares LLCP would have been entitled to transfer to the purchaser under
     Section 3.4 had the Prohibited Transfer been effected pursuant to and in
     compliance with the terms of Sections 3.1 through 3.6. Such sale shall be
     made on the following terms and conditions:

               (i)   The price per share at which shares are to be sold to
          such Principal Shareholder shall be equal to the price per share paid
          by the purchaser to such Principal Shareholder in the Prohibited
          Transfer. Such Principal Shareholder shall also reimburse LLCP for any
          and all fees and expenses, including attorneys, accountants and other
          expenses, incurred pursuant to the exercise or attempted exercise of
          LLCP's rights under Section 3;

               (ii)  Within thirty (30) days after the later of the dates on
          which LLCP (a) received notice of the Prohibited Transfer or (b)
          otherwise became aware of the Prohibited Transfer, LLCP shall, if
          exercising the Prohibited Transfer Put, deliver to such Principal
          Shareholder the certificate or certificates representing the shares to
          be sold, each certificate to be properly endorsed for transfer;

               (iii) Such Principal Shareholder shall, upon receipt of the
          certificate or certificates representing the shares to be sold by
          LLCP, pay the aggregate purchase price therefor and the amount of
          reimbursable fees and expenses, as specified in Section 3.9(b)(i), by
          wire transfer in immediately available funds; and

               (iv)  Notwithstanding the foregoing, any attempt by any
          Principal Shareholder to transfer any Co-Sale Shares in violation of
          Section 3 shall be deemed a material breach of this Agreement and, to
          the extent permitted by Applicable Law, be void, and the Company
          agrees that it will not effect such a transfer, nor will it treat any
          alleged transferee as the holder of such shares, without the written
          consent of LLCP.

     3.10 Termination. The rights granted to LLCP under this Section 3 shall
expire on the earlier to occur of (a) November 24, 2009, and (b) the date upon
which the number of shares of Common Stock (calculated on an "as-if-converted"
basis) owned or held, directly or indirectly, by LLCP at any time is less than
five percent (5.0%) of the number of shares of Common Stock on a Fully Diluted
Basis at such time.

4.   RIGHT OF FIRST REFUSAL.

     4.1  The Company hereby grants to LLCP the right to purchase up to the LLCP
Pro Rata Share (as such term is defined below) of any New Securities (as such
term is defined below) which the Company may from time to time propose to issue
or sell, and the Company shall not issue or sell any New Securities without
first complying with the

                                      -10-

<PAGE>

provisions of this Section 4. LLCP's right to purchase shall be at the same
price applicable to such issuance or sale of New Securities. The term "LLCP Pro
Rata Share" shall be equal to a percentage, calculated immediately prior to the
issuance of any New Securities, based upon a fraction, (a) the numerator of
which is equal to the (i) total number of shares of Common Stock beneficially
owned, directly or indirectly, by LLCP immediately prior to such issuance, plus
(ii) the total number of shares of Common Stock issuable upon exercise or
conversion of any Option Rights held directly or indirectly, by LLCP immediately
prior to such issuance, and (b) the denominator of which is the sum of (i) the
total number of shares of Common Stock issued and outstanding (calculated on an
"as-if-converted" basis) immediately prior to such issuance, plus (ii) the total
number of shares of Common Stock issuable upon exercise or conversion of any
Option Rights held directly or indirectly, by LLCP immediately prior to such
issuance.

     4.2   The term "New Securities" shall mean any Capital Stock (including
Common Stock and preferred stock) of the Company whether now authorized or not,
and any Option Rights of the Company; provided, however, that the term New
Securities does not include (a) any equity securities issued in a public
offering pursuant to an effective registration statement under the Securities
Act with an aggregate offering price to the public of at least $10,000,000,
provided that such equity securities are listed at the time of issuance on a
recognized national securities exchange or on the NASDAQ National Market, (b)
any Option Rights to purchase shares of Common Stock granted by the Company,
whether prior to or after the date hereof, to directors, officers or key
employees of the Company or any of its Affiliates under any Company Stock Plan
existing on the date hereof, and shares of Common Stock issuable upon exercise
of such Option Rights.

     4.3   If the Company proposes from time to time to undertake any issuance
of New Securities, it shall give LLCP written notice (an "Issuance Notice") of
such proposed issuance, describing the type of New Securities, the proposed
offer price and the general terms upon which the Company proposes to issue the
same. LLCP shall have thirty (30) days after its receipt of the Issuance Notice
to decide whether it wishes to purchase up to the LLCP Pro Rata Share of the New
Securities for the price and upon the terms specified in the Issuance Notice by
furnishing written notice to the Company (a "Purchase Notice") indicating the
number of New Securities to be purchased by LLCP. To the extent that LLCP shall
have timely furnished a Purchase Notice to the Company, the Company shall, at
the closing of the issuance of such New Securities, sell to LLCP such number of
New Securities as LLCP shall have notified the Company that it intends to
purchase in the applicable Purchase Notice on the terms set forth in the
Issuance Notice.

     4.4   The rights granted to LLCP under this Section 4 shall expire on the
earlier to occur of (a) November 24, 2009, and (b) the date upon which the
number of shares of Common Stock (calculated on an "as-if-converted" basis)
owned or held, directly or indirectly, by LLCP at any time is less than five
percent (5.0%) of the number of shares of Common Stock on a Fully Diluted Basis
at such time.

5.   CERTAIN ISSUANCES OF OPTION RIGHTS; COMPANY STOCK PLANS.

     5.1   The Board (or any compensation committee thereof) shall not grant any
Option Rights of the Company to directors, officers, consultants and key
employees of the

                                      -11-

<PAGE>

Company or of any Affiliate of the Company unless (a) such grant is made under
any Company Stock Plan existing on the date of grant at an exercise price per
share that is not less than fair market value on the date of grant, and (b) such
grant has been duly approved (i) in the case of a grant to any officer (other
than a senior executive officer) or employee of the Company who is not a member
of the Board, by a majority vote of the Board, and (ii) in the case of any grant
to a senior executive officer, a member of the Board or a consultant, by the
unanimous vote (or written consent) of the disinterested members of the Board.

     5.2   The Company shall not at any time amend, supplement or otherwise
modify any Company Stock Plan existing at such time, or adopt or approve any
stock option or stock purchase plan, agreement or arrangement after the date
hereof, without the prior affirmative vote or written consent of the
shareholders of the Company (including the prior affirmative vote or written
consent of LLCP).

6.   CERTAIN ANTI-DILUTION PROTECTION.

     6.1   The Company acknowledges and covenants with the Purchaser that the
number of shares of Capital Stock of the Company beneficially owned by LLCP on a
Fully Diluted Basis (including after giving effect to the shares of Capital
Stock of the Company reserved or to be reserved for issuance under any Company
Stock Plan immediately following the Spin-Off shall represent not less than
24.0% of the total number of shares of Capital Stock of the Company on a Fully
Diluted Basis at such time. In the event that the number of shares of Capital
Stock of the Company beneficially owned by LLCP on a Fully Diluted Basis
immediately following the Spin-Off equals more than 24.0% of the total number of
shares of Capital Stock of the Company on a Fully Diluted Basis immediately
following the Spin-Off, LLCP shall, at the request of the Company, surrender to
the Company a number of shares of Common Stock such that the number of shares of
Capital Stock of the Company beneficially owned by LLCP immediately following
the Spin-Off equals not less than 24.0% of the total number of shares of Capital
Stock of the Company on a Fully Diluted Basis immediately following the
Spin-Off. In the event that the number of shares of Capital Stock of the Company
beneficially owned by LLCP on a Fully Diluted Basis immediately following the
Spin-Off equals less than 24.0% of the total number of shares of Capital Stock
of the Company on a Fully Diluted Basis immediately following the Spin-Off, the
Company agrees to issue to LLCP, at no additional cost to LLCP, a number of
additional shares of Common Stock such that, when added to the number of shares
of Capital Stock of the Company beneficially owned by LLCP on a Fully Diluted
Basis immediately following the Spin-Off, LLCP would own not less than 24.0% of
the total number of shares of Capital Stock of the Company on a Fully Diluted
Basis immediately following the Spin-Off.

     6.2   If, at the time LLCP owns or holds any Warrant Shares, any event
occurs which would have resulted in an adjustment to the exercise price of the
Warrant Shares, or the number of Warrant Shares issuable to LLCP, had the
Warrant not been exercised (a "Warrant Dilutive Issuance"), the Company shall
issue to LLCP on the effective date of such Warrant Dilutive Issuance, without
further payment of any kind, a number of additional shares of Common Stock equal
to the difference between (a) the number of shares of Common Stock which would
have been issuable upon exercise of the Warrant had the

                                      -12-

<PAGE>

Warrant not been exercised in any part, after giving effect to such Dilutive
Issuance, and (b) the number of Warrant Shares issued to LLCP upon exercise of
the Warrant.

7.   MISCELLANEOUS.

     7.1   Legends. All certificates representing shares of capital stock of the
Company now owned or held or hereafter acquired by any Principal Shareholder
shall have stamped or endorsed thereon a legend substantially in the following
form (in addition to any legends required under applicable state securities
laws):

           THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES
           REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND
           CONDITIONS OF AN AMENDED AND RESTATED INVESTOR RIGHTS
           AGREEMENT BY AND AMONG THE HOLDER, THE COMPANY AND OTHERS. A
           COPY OF SUCH AGREEMENT MAY BE OBTAINED FROM THE COMPANY UPON
           WRITTEN REQUEST.

     7.2   Stock Transfer Records. The Company shall make appropriate notations
in its stock transfer records of the restrictions on transfer provided for in
this Agreement and shall not record any transfers of capital stock of the
Company not made in strict compliance with the terms of this Agreement. The
Company acknowledges that any such transfer shall constitute an Event of Default
under Section 10.1 of the Securities Purchase Agreement.

     7.3   Assignments. The rights and obligations of LLCP under this Agreement
shall be freely assignable or delegable, as the case may be, in connection with
any transfer of the Warrant Shares, in whole or in part; provided, however, that
the rights of LLCP under Section 1 may not be assigned except in connection with
any transfer of Warrant Shares to an Affiliate of LLCP. Any assignee of such
rights shall be entitled to all of the benefits of this Agreement as if such
assignee were an original party hereto. The rights and obligations of the
Company and the Principal Shareholders may not be assigned or delegated, as the
case may be, without LLCP's prior written consent, except that any Principal
Shareholder may, without LLCP's consent, assign its rights, but not delegate its
obligations, to any transferee under Section 3.1(c).

     7.4   Entire Agreement. This Agreement represents the final agreement among
the parties with respect to the matters set forth herein and supersedes any
prior oral or written, or any contemporaneous oral, agreements or understandings
of the parties. Nothing in this Agreement or in the other Investment Document,
expressed or implied, is intended to confer upon any party other than the
parties hereto or thereto any rights, remedies, or liabilities under or by
reason of this Agreement or the other Investment Documents.

     7.5   Notices. All notices, requests, demands and other communications
which are required or may be given under this Agreement shall be in writing and

illegal, invalid, or unenforceable under present or future Applicable Laws
during the term thereof, such provision shall be fully severable, this Agreement

remaining provisions thereof shall remain in fill force and effect and shall not
be affected by the illegal, invalid, or unenforceable provision or by its
severance therefrom. Furthermore, in lieu of such illegal, invalid, or
unenforceable provision there shall be added automatically as a part of this
Agreement a legal, valid, and enforceable provision as similar in terms to the
illegal, invalid, or unenforceable provision as may be possible.

     7.7   Counterparts. This Agreement may be executed in two or more
counterparts and by facsimile transmission, each of which shall be an original,
but all of which together shall constitute one instrument.

     7.8   Construction and Interpretation. The rules of construction set forth

the construction and interpretation of this Agreement.

     7.9   Amendments; Successors and Assigns. This Agreement may be amended,
supplemented or otherwise modified by a writing signed by the Company and LLCP
only; provided, however, that no amendment, supplement or other modification may
be made to this Agreement which materially adversely affects any Principal
Shareholder without the written consent of such Principal Shareholder. Any
amendment or other modification effected in accordance with this Section 7.9
shall be binding upon, and inure to the benefit of, the Company, the Principal
Shareholders, LLCP and their respective successors and permitted assigns.

     7.10  Remedies. In the event that the Company or any Principal Shareholder
fails to observe or perform any covenant or agreement to be observed or
performed by it or him under this Agreement, LLCP may proceed to protect and
enforce its rights by suit in equity or action at law, whether for specific
performance of any term contained in this Agreement or for an injunction against
the breach of any such term or in aid of the exercise of any power granted in
this Agreement or to enforce any other legal or equitable right of LLCP, or to
take any one or more of such actions. The Company agrees to pay all fees, costs,
and expenses, including fees and expenses of attorneys, accountants and other
experts retained by LLCP, and all fees, costs and expenses of appeals incurred
or expended by LLCP in connection with the enforcement of this Agreement or the
collection of any sums due hereunder, whether or not suit is commenced. None of
the rights, powers or remedies conferred under this Agreement shall be mutually
exclusive, and each such right, power or remedy shall be cumulative and in
addition to any other right, power or remedy whether conferred by this Agreement
or now or hereafter available at law, in equity, by statute or otherwise.

     7.11  Representations by Principal Shareholders. Each Principal Shareholder
hereby represents and warrants to LLCP that (a) he has carefully read this
Agreement and has had sufficient time and opportunity to consider its terms and

execute, deliver and perform his obligations under this Agreement, without

                                      -15-

<PAGE>

execution and delivery of this Agreement by the Principal Shareholder, and the
performance by the Principal Shareholder of his obligations hereunder, does not
and will not breach or violate any agreement, instrument or other document to
which the Principal Shareholder is a party or to which the Principal
Shareholder's assets are bound or any Applicable Laws and (e) he has delivered
to LLCP a duly executed Spousal Consent, substantially in the form of Exhibit A.

     7.12   Governing Law. In all respects, including all matters of
construction, validity and performance, this Agreement and the rights and

     7.14   Amendment and Restatement. Effective on and as of the Effective
Date, this Agreement shall supersede the Original Investor Rights Agreement
insofar as the two are inconsistent. However, the execution and delivery of this
Agreement shall not excuse, or constitute a waiver of, any Defaults or Events of
Default under the Original Investor Rights Agreement, it being understood that
this Agreement is not a termination of the Original Investor Rights Agreement,
but is a modification (and, as modified, a continuation) of the Original
Investor Rights Agreement. The Company acknowledges and agrees that the Original
Investor Rights Agreement, as amended and restated hereby, is affirmed in all
respects.

     7.15   WAIVER OF TRIAL BY JURY. EACH PARTY HEREBY KNOWINGLY, INTENTIONALLY

                              AMENDED AND RESTATED
                            INVESTOR RIGHTS AGREEMENT

     THIS AMENDED AND RESTATED INVESTOR RIGHTS AGREEMENT is entered into as of
the ____ day of _________ 2002 (this "Agreement"), by and among OVERHILL FARMS,
INC., a Nevada corporation (the "Company"), JAMES RUDIS, an individual
("Rudis"), WILLIAM E. SHATLEY, an individual ("Shatley"), and LEVINE LEICHTMAN
CAPITAL PARTNERS II, L.P., a California limited partnership ("LLCP"). Rudis and
Shatley are referred to herein individually as a "Principal Shareholder" and
collectively as the "Principal Shareholders."

                                 R E C I T A L S

     A.   The Company, OVERHILL CORPORATION (formerly known as Polyphase
Corporation and to be known from and after the effective date of the Spin-Off as
TreeCon Resources, Inc.), a Nevada corporation ("Parent"), Overhill Ventures and
LLCP entered into that certain Securities Purchase Agreement dated as of
November 24, 1999, as amended by that certain Consent and First Amendment to
Securities Purchase Agreement dated as of August 23, 2000, and as further
amended by that certain Second Amendment to Securities Purchase Agreement dated
as of January 11, 2002, that certain Consent and Third Amendment dated as of
January 31, 2002, that certain Fourth Amendment dated as of June 28, 2002, and
that certain Fifth Amendment to Securities Purchase Agreement dated as of
September 11, 2002 (as so amended, the "Original Securities Purchase
Agreement").

     B.   In connection with the execution and delivery of the Original
Securities Purchase Agreement, the Company, Parent and LLCP entered into that
certain Investor Rights Agreement dated as of November 24, 1999, as amended by
an Amendment to Investor Rights Agreement dated as of August 25, 2000, and as
further amended by a Second Amendment to Investor Rights Agreement dated as of
January 11, 2002 (as so amended, the "Original Investor Rights Agreement"),
pursuant to which, among other things, the Company and Parent granted to LLCP
certain investment monitoring and other rights all as described therein.

     C.   The Board of Directors of Parent has previously approved a plan to
distribute to its stockholders on a pro rata basis in the form of a stock
dividend the shares of Common Stock owned or held by Parent and thereby "spin
off" the Company as a separate, independent publicly traded company (the
"Spin-Off"). Immediately following the Spin-Off, Parent will not beneficially
own or hold any shares of, or any Option Rights with respect to, the Capital
Stock of the Company.

     D.   The Company, the entities from time to time parties thereto as
Guarantors and LLCP are concurrently entering into that certain Amended and
Restated Securities Purchase Agreement dated of even date herewith (as amended
from time to time, the "Securities Purchase Agreement") pursuant to which, among
other things, (a) the parties

<PAGE>

thereto are amending and restating the Original Securities Purchase Agreement,
the Original Note and the Original Warrant and (b) at the request of the
Company, LLCP is consenting to the Spin-Off Related Matters, all on the terms
and subject to the conditions set forth therein. Unless otherwise indicated, all
capitalized terms used and not otherwise defined herein have the meanings
ascribed to them in the Securities Purchase Agreement or the Original Investor
Rights Agreement, as the case may be.

     E.   Rudis is the current President and Chief Executive Officer of the
Company and Shatley is a Senior Vice President of the Company. Immediately
following the Spin-Off, Rudis will be the beneficial owner of _________ shares
of Common Stock, par value $0.01 per share, of the Company ("Common Stock"),
including options to purchase _____ shares of Common Stock issued under the 2002
Stock Option Plan, and Shatley will be the beneficial owner of _________ shares
of Common Stock, including options to purchase _____ shares of Common Stock
issued under the 2002 Stock Option Plan.

     F.   It is a condition precedent to the effectiveness of the Securities
Purchase Agreement, including the consent of LLCP to the Spin-Off Related
Matters, that the Company affirm, amend and restate the Original Investor Rights
Agreement on the terms and conditions contained herein, and the Principal
Shareholders become parties to this Agreement.

     G.   It is intended that the Spin-Off will not constitute a transaction
that would trigger LLCP's "co-sale" rights under Section 3 of the Original
Investor Rights Agreement, and that because Parent will not be liable for the
debts, liabilities or obligations of the Company or beneficially own or hold any
shares of Capital Stock of the Company from and after the date hereof, Parent
will no longer be a party to this Agreement from and after the date hereof.

                                A G R E E M E N T

     NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereby amend and
restate the Original Investor Rights Agreement as follows:

1.   INVESTMENT MONITORING RIGHTS.

     1.1  Election of LLCP Representative to Board.

          (a)  LLCP shall have the right, exercisable from time to time, to
     require the Company to cause to be nominated and elected or appointed to
     the Board of Directors of the Company (the "Board") an individual
     designated by LLCP in an LLCP Representative Request (as such term is
     defined below) (the "LLCP Representative") furnished by LLCP to the Company
     and each Principal Shareholder. If LLCP wishes to have an individual
     elected or appointed as a member of the Board, LLCP shall deliver to the
     Company, with a copy to each Principal Shareholder, a written request (an
     "LLCP Representative Request") notifying the Company of LLCP's election
     under this Section 1.1 to have an LLCP

                                      -2-

<PAGE>

     Representative nominated and elected or appointed to the Board and
     designating the individual to be so nominated, elected or appointed.

          (b)  Within five (5) Business Days after the Company receives an LLCP
     Representative Request, the Company shall take (or cause to be taken) as
     soon as practicable any and all actions as may be necessary or advisable to
     cause the LLCP Representative to be nominated and elected or appointed to
     the Board and to remain a duly elected or appointed member of the Board
     (including, among other actions, nominating the LLCP Representative to be a
     member of the Board, creating a vacancy for the LLCP Representative or
     increasing the size of the Board and filling the resulting vacancy with the
     LLCP Representative, as applicable).

          (c)  Removal. No individual serving as the LLCP Representative may be
     removed from the Board without the prior written approval of LLCP other
     than for "cause." For purposes of this Section 1.1(c), the term "cause"
     shall mean a conviction (treating a nolo contendere plea or a guilty plea
     as a conviction) of a felony or of a crime of moral turpitude. If any LLCP
     Representative shall be removed from the Board for cause, then LLCP shall
     have the sole right to designate another individual to serve as the LLCP
     Representative, and the Company shall, upon the request of LLCP, promptly
     (and in any event within five (5) Business Days of such request) take any
     and all actions as may be necessary or appropriate to cause such other
     individual to be nominated and elected or appointed to the Board as the
     LLCP Representative.

          (d)  Vacancy. In the event of the death or resignation, or removal by
     LLCP, of the LLCP Representative at any time, or in the event the LLCP
     Representative shall not be elected to the Board for any reason, the
     Company shall, upon the request of LLCP, promptly (and in any event within
     five (5) Business Days of such request) take any and all actions as may be
     necessary or appropriate to cause another individual designated by LLCP to
     be nominated and elected or appointed to the Board as the LLCP
     Representative. Such actions may include, but not be limited to, calling
     and/or holding, in accordance with the Bylaws of the Company and Applicable
     Laws, a special meeting of the Board or obtaining the written consent of
     all members of the Board or, if possible, the shareholders holding at least
     the requisite number of shares necessary to elect or appoint such
     individual as a member of the Board, as the case may be.

          (e)  Committees. To the extent that the Board delegates any of its
     duties to any committee(s) of the Board, the LLCP Representative shall,
     upon the request of LLCP, be appointed to such committee(s).

     1.2  Agreement to Vote.

          (a)  The Principal Shareholders each agree to hold all of his
     Principal Shareholder Shares subject to, and to vote the Principal
     Shareholder Shares in accordance with, the provisions of this Agreement.
     The term "Principal Shareholder Shares" shall mean, with respect to any
     Principal Shareholder, any and all Capital Stock and other voting
     securities of the Company beneficially owned or

                                      -3-

<PAGE>

     held by him, or registered in his name, on the date hereof, and any and all
     Capital Stock and other voting securities of the Company owned or held by
     him, or registered in his name, after the date hereof, and any securities
     of the Company issued with respect to, upon conversion of, or in exchange
     or substitution for, such securities.

          (b)  On all matters relating to the election or appointment of members
     of the Board, each Principal Shareholder agrees, on behalf of himself and
     any transferee or assignee of Principal Shareholder Shares, to vote all of
     his Principal Shareholder Shares (or to consent pursuant to any action by
     written consent) in favor of electing or appointing the LLCP Representative
     to the Board.

          (c)  Enforceable Voting Agreement. The agreements set forth in this
     Section 1.2 are intended to constitute enforceable voting agreements within
     the scope of Section 706(a) of the General Corporation Law of the State of
     California.

     1.3  Observation Rights. In addition to the rights granted to LLCP in this
Section 1.1, if, at any time, no LLCP Representative is serving on the Board for
any reason, LLCP shall be entitled to receive written notice of, and to have one
(1) representative and one (1) advisor to such representative (or, at LLCP's
election, two (2) representatives) attend as observers at, all meetings of the
Board (and of all committees thereof) and all meetings of the shareholders of
the Company. Written notice of all such meetings shall be given to LLCP in the
same manner and at the same time, to the extent permitted by Applicable Laws, as
to the members of the Board or such committees (which in any event shall not be
less than forty-eight (48) hours prior to such meeting unless otherwise agreed
to by LLCP in advance and in writing) and at the same time as to the
shareholders of the Company, as the case may be. The Company shall furnish LLCP
with copies of (i) the meeting agenda, if any is prepared, (ii) all information
that is furnished to the members of the Board (or such committees) or to the
shareholders of the Company (whether prior to, at, or subsequent to any such
meetings), as the case may be, at the same time as such materials are furnished
to the members of the Board or such committee or to the shareholders of the
Company, as the case may be, and (iii) copies of the minutes of all meetings of
the Board (and such committees) and of all meetings of shareholders concurrently
with the distribution of such minutes to one or more members of the Board (or
such committees) or shareholders, as the case may be, but in no event later than
forty-five (45) days after each such meeting.

     1.4  Operating Committee.

          (a)  Under the Original Investor Rights Agreement, the Company
     established for the benefit of LLCP an operating committee (the "Operating
     Committee") to, among other things, (i) review the annual operating and
     capital budget of the Company and its Subsidiaries; (ii) compare budgeted
     versus actual performance of the Company and its Subsidiaries; (iii)
     analyze working capital management; and (iv) review the cash flow
     performance of the Company and its Subsidiaries. The Operating Committee
     shall also consider such additional financial matters as it shall deem
     advisable. The Operating Committee shall not constitute a committee
     designated by the Board pursuant to the Company's Bylaws or NRS 78.125, and
     shall not have any authority to act in the name of or on behalf of

                                      -4-

<PAGE>

     the Company or any of its Subsidiaries, but the Operating Committee shall
     have the right to make suggestions and to recommend actions to the Board or
     to the Board of Directors of any Subsidiary of the Company or to any
     committee of any such Board of Directors, either in writing or by
     attending, through a representative, a meeting of such Board of Directors
     or such committee.

          (b)  The Operating Committee shall at all times be comprised of at
     least two (2) members of senior management of the Company, who initially
     shall be James Rudis, the current President and Chief Executive Officer of
     the Company, and Richard A. Horvath, the current Chief Financial Officer of
     the Company, and two (2) members designated by LLCP (who shall be
     representatives of Levine Leichtman Capital Partners, Inc. ("LLCP Inc."),
     an Affiliate of LLCP). The financial officers and other members of senior
     management of the Company shall be available, in person or by telephone, at
     each meeting of the Operating Committee to review financial information and
     discuss other matters.

          (c)  Regular meetings of the Operating Committee shall take place on
     or about the third Tuesday of each calendar month, unless otherwise agreed.
     Meetings may be conducted by telephone so long as each of the persons
     attending can hear each of the other persons attending the meeting. The
     Company's financial officers shall prepare a financial package for delivery
     to all Operating Committee members at least forty-eight (48) hours prior to
     each regularly scheduled monthly meeting. The financial package shall
     include, among other things, (i) a consolidated and consolidating balance
     sheet, statement of operations and statement of cash flows of the Company
     and its Subsidiaries for the most recent one-month period and for the
     year-to-date period, (ii) a comparison of the actual results of operations
     for such periods to the same periods in the prior year and to the budget
     and forecast, (iii) an explanation of any variances in such actual results
     of operations from such budget and forecast, (iv) the status of any
     permitted dispositions of assets by the Company or its Subsidiaries, (v) an
     update of the status of all litigation or similar proceedings pending
     against the Company or any of its officers, directors, Subsidiaries or
     other Affiliates and (vii) such other information regarding the Company or
     its Subsidiaries as any member of the Operating Committee may from time to
     time request.

     1.5  [Intentionally Omitted]

     1.6  Consulting Fees.

          (a)  In consideration of consulting services rendered and which may be
     rendered by LLCP or LLCP Inc. to the Company under this Section 1
     (including in connection with the exercise of the observation and other
     rights granted under Section 1.3 or during any Operating Committee
     meetings) during the five (5) twelve-month periods immediately following
     the Initial Closing Date, which services are hereby acknowledged by the
     Company as being substantial and valuable to its business and operations,
     the Company agrees to pay to LLCP Inc. a consulting fee in the aggregate
     amount of $900,000. The Company agrees that the full amount of such
     consulting fee shall be fully earned as of the Initial Closing Date
     (whether or not the Note remains outstanding at all times during the entire
     five (5) twelve-month

                                      -5-

<PAGE>

     period), but that such consulting fee shall be payable in five (5) equal
     installments of $180,000 each and shall be due on the following dates:
     January 10, 2000, January 10, 2001, January 10, 2002, January 10, 2003 and
     January 10, 2004; provided, however, that upon the earlier to occur of (i)
     a Change in Control and (ii) the date upon which all Obligations under the
     Note shall have been paid in cash in full, the portion of the consulting
     fee remaining unpaid shall at such time become immediately due and payable
     to LLCP Inc.

          (b)  [Intentionally Omitted.]

          (c)  The consulting fees payable to LLCP Inc. under this Section 1.6
     shall be paid by wire transfer in immediately available funds to a bank
     account designated by LLCP Inc. In no event shall LLCP Inc. be obligated to
     refund or waive its receipt of all or any portion of the consulting fees
     payable to it hereunder for any reason.

          (d)  In addition, the Company agrees to pay to LLCP Inc. a
     non-refundable monthly consulting fee in the amount of $12,000 for each
     calendar month (or portion thereof) during the period commencing on
     February 1, 2002, and ending on the date upon which all Obligations under
     the Note have been paid in cash in full. Each monthly consulting fee shall
     be due and payable in advance on the first Business Day of each such
     calendar month.

     1.7  Survival of Rights. The rights granted to LLCP under Section 1.1
(Agreement to Vote) and Section 1.3 (Observation Rights) became effective as of
the Initial Closing Date and shall continue for so long as LLCP continues to
hold, directly or indirectly, at least $2,500,000 in outstanding principal
amount of the Note, or at least five percent (5.0%) of the shares of Common
Stock calculated on a Fully Diluted Basis. The rights granted to LLCP under
Section 1.4 (Operating Committee) became effective as of the Initial Closing
Date and shall continue for so long as any principal amount of the Note remains
outstanding. Notwithstanding anything to the contrary contained herein or
otherwise, the rights granted to LLCP under Section 1.1 (Agreement to Vote),
Section 1.3 (Observation Rights) and Section 1.4 (Operating Committee) shall
survive to the extent that LLCP holds the Note or any Warrant Shares and informs
the Company in writing that it believes in good faith that it is required to
retain such rights to qualify as a "venture capital operating company" for
purposes of complying with ERISA.

2.   INDEMNIFICATION AND INSURANCE.

     2.1  The Company shall, to the maximum extent permitted by Applicable Law,
indemnify, defend and hold harmless the LLCP Representative, any LLCP
representatives participating in the Operating Committee, LLCP and the
employees, partners, principals, agents, attorneys, accountants, representatives
and Affiliates of LLCP (including LLCP Inc.) (individually, an "LLCP Party" and,
collectively, the "LLCP Parties"), from and against all costs, expenses,
liabilities, claims, judgments, damages and losses, including all attorneys'
fees and the cost of preparation and investigation, incurred in connection with
any threatened, pending or completed action or proceeding, whether civil,
criminal, administrative or investigative (collectively, "Liabilities and
Costs"), arising out of or in any way related to the fact that any LLCP Party is
or was a director, officer, employee or

                                      -6-

<PAGE>

other agent of the Company or any subsidiary of the Company, is or was serving
on the Operating Committee, is or was serving as an observer of the Board, or is
or was serving at the request of the Company as a director, officer, employee,
trustee, agent or fiduciary of another corporation, partnership, joint venture,
employee benefit plan, trust or other enterprise.

     2.2  Upon request by any LLCP Party, the Company shall advance (within five
(5) Business Days of such request) any and all expenses, including any and all
attorneys' fees and the cost of any investigation and preparation incurred in
connection with any matter for which such LLCP Party is or may be entitled to
indemnification hereunder; provided, however, that if and to the extent that a
court of competent jurisdiction finally determines that such LLCP Party is not
permitted to be indemnified with respect to such matter under Applicable Law,
the Company shall be entitled to be reimbursed for any expenses so advanced. The
Company shall also indemnify each LLCP Party from and against any and all
Liabilities and Costs incurred in connection with any claim or action brought to
enforce such LLCP Party's rights under this Section 2, or under Applicable Law
or the Company's charter or bylaws now or hereafter in effect relating to
indemnification, or for recovery under directors' and officers' liability
insurance policies maintained by the Company, regardless of whether such LLCP
Party is ultimately determined to be entitled to such indemnification or
insurance recovery, as the case may be. If, for any reason, the foregoing
indemnification is not available for any reason or is not sufficient to
indemnify and hold the LLCP Parties harmless from all such Liabilities and
Costs, the Company shall contribute to the amount of all such Liabilities and
Costs paid or payable by any LLCP Party in such proportion as is appropriate to
reflect not only the relative benefits received by the Company, on the one hand,
and LLCP, on the other hand, but also the relative fault of each, as well as any
other equitable considerations. The Company's reimbursement, indemnity and
contribution obligations shall be in addition to any liability the Company may
otherwise have at law or under any other agreement, including the Securities
Purchase Agreement, and such obligations shall extend, upon the same terms, to
all LLCP Parties. This Section 2 shall survive the termination of this Agreement
indefinitely.

     2.3  During the term of this Agreement, the Company shall maintain in force
and effect one or more policies of insurance covering directors and officers
liability in an insured amount of not less than $10,000,000. Such insurance
policies shall cover, among other things, claims asserted under federal and
state securities laws and such other matters as are customary and appropriate
for publicly traded companies operating in the Company's industry.

3.   CO-SALE AGREEMENT.

     3.1  If any Principal Shareholder (a "Selling Principal Shareholder")
proposes to sell or transfer (a "sale") any Principal Shareholder Shares
("Co-Sale Shares") to a bona fide purchaser or transferee (a "purchaser") in one
(1) transaction or any series of related transactions, such Principal
Shareholder shall promptly give written notice (the "Co-Sale Notice") to the
Company and to LLCP at least thirty (30) days prior to the closing of such sale.
The Co-Sale Notice shall describe in reasonable detail the terms of the proposed
sale, including the number of Co-Sale Shares to be sold, the nature of the sale,
the amount of consideration to be paid and the name and address of the proposed
purchaser.

                                      -7-

<PAGE>

Notwithstanding the foregoing, without complying with the procedures of this
Section 3, (a) Rudis may sell up to an aggregate of 50,000 Principal Shareholder
Shares in open market transactions (not in a private sale transaction) during
any Fiscal Year of the Company, it being understood that a Change in Control
shall occur if Rudis ceases to beneficially own or hold less than 300,000 shares
of Common Stock at any time, (b) Shatley may sell up to an aggregate of 50,000
shares in open market transactions (not in a private sale transaction) during
any Fiscal Year of the Company, it being understood that a Change in Control
shall occur if Shatley ceases to beneficially own or hold less than 150,000
shares of Common Stock at any time and (c) any Principal Shareholder may
transfer his Principal Shareholder Shares to his spouse or descendants or to
trusts or family partnerships established for the benefit of himself or such
persons, provided that such Principal Shareholder provides to LLCP at least
thirty (30) days prior written notice of such transfer and the transferee
executes a joinder agreement, in form and substance satisfactory to LLCP,
pursuant to which such transfer becomes bound by, and agrees to comply with, the
provisions of this Agreement as if such transferee were a Principal Shareholder.

     3.2  LLCP shall have the right, exercisable by furnishing written notice to
the Selling Principal Shareholder within twenty (20) days after its receipt of
the Co-Sale Notice, to participate in such sale on the same terms and conditions
as specified in the Co-Sale Notice. To the extent that LLCP exercises such right
of participation in accordance with the terms set forth in this Section 3, the
number of Co-Sale Shares that the Selling Principal Shareholder may sell in the
transaction(s) shall be proportionately reduced.

     3.3  If there shall be a decrease in the price to be paid by the proposed
purchaser for the Co-Sale Shares from the price set forth in the Co-Sale Notice,
which decrease is acceptable to the Selling Principal Shareholder, or there is
any other material change to the terms or conditions set forth in the Co-Sale
Notice which is less favorable to the Selling Principal Shareholder but which is
acceptable to him, the Selling Principal Shareholder shall immediately notify
LLCP in writing of such decrease or other change. LLCP shall have the right to
participate in such sale on such modified terms by furnishing written notice to
the Selling Principal Shareholder within (a) if LLCP has not yet delivered a
notice to the Principal Shareholder pursuant to Section 3.2, the greater of (i)
the remaining number of days in the twenty (20) day period set forth in Section
3.2 and (ii) ten (10) Business Days from the date of its receipt of such written
notice, or (b) if LLCP has delivered a written notice to the Selling Principal
Shareholder pursuant to Section 3.2, ten (10) Business Days from the date of its
receipt of such written notice to modify the terms set forth in the written
notice it previously furnished to the Selling Principal Shareholder.

     3.4  LLCP may sell at the time of sale all or any portion of that number of
shares of Capital Stock of the Company beneficially owned or held by it equal to
the product of (a) the aggregate number of Co-Sale Shares covered by the Co-Sale
Notice, multiplied by (ii) a fraction, the numerator of which is the total
number of shares of Common Stock beneficially owned, directly or indirectly, by
LLCP at the time of sale (including the Warrant Shares and the shares of Common
Stock issued or issuable upon exercise or conversion of any Option Rights of the
Company (including the Series A Preferred Shares) beneficially owned, directly
or indirectly, by LLCP) (collectively, the "LLCP Shares"), and the denominator
of which is the sum of the total number of shares of Common Stock beneficially
owned by the Selling Principal Shareholder and the total number of LLCP

                                      -8-

<PAGE>

Shares at the time of sale. In no event shall LLCP be required to make any
representation or warranty in connection with the sale to any purchaser other
than as to the organization and authority of LLCP, title to the LLCP Shares to
be sold and the absence of conflicts with organizational documents and material
agreements.

     3.5  LLCP shall effect its participation in the sale by promptly delivering
to the Selling Principal Shareholder at the closing of the sale of the Co-Sale
Shares, for transfer to the prospective purchaser, one or more certificates,
properly endorsed for transfer, which represent the type and number of shares of
Capital Stock of the Company which LLCP elects to sell.

     3.6  The Selling Principal Shareholder shall transfer the certificate or
certificates that LLCP delivers to the Selling Principal Shareholder pursuant to
Section 3.5 to the purchaser on the terms and conditions specified in the
Co-Sale Notice, and the Selling Principal Shareholder shall cause the purchaser
to remit to LLCP directly, concurrently with the closing and in immediately
available funds to an account designated by LLCP, that portion of the sale
proceeds to which LLCP is entitled by reason of LLCP's participation in the
sale. To the extent that any purchaser refuses to purchase shares or other
securities from LLCP, the Selling Principal Shareholder shall not sell to such
purchaser any shares of Capital Stock of the Company unless and until,
simultaneously with such sale, the Selling Principal Shareholder shall purchase
such shares or other securities from LLCP. Subject to the foregoing sentence, if
the Selling Principal Shareholder does not complete the proposed sale for any
reason, the Selling Principal Shareholder shall immediately return to LLCP all
documents (including all stock certificates, stock assignments and/or powers of
attorney) which LLCP delivered to the Selling Principal Shareholder pursuant to
this Section 3 or otherwise in connection with such sale.

     3.7  The exercise or non-exercise of the rights of LLCP hereunder to
participate in one or more sales of Co-Sale Shares by the Selling Principal
Shareholder shall not adversely affect its rights to participate in subsequent
sales of Co-Sale Shares by any Principal Shareholder.

     3.8  The provisions of Section 3 shall not apply to the sale of any Co-Sale
Shares (a) to the public pursuant to a registration statement filed with, and
declared effective by, the Commission under the Securities Act or (b) to the
Company.

     3.9  Prohibited Transfers.

          (a)  If any Principal Shareholder sells (or enters into any agreement,
     arrangement or understanding to sell) any Co-Sale Shares in violation or
     contravention of the co-sale rights of LLCP under this Section 3 (a
     "Prohibited Transfer"), LLCP shall have, in addition to all other rights,
     powers or remedies available at law, in equity, under this Agreement or any
     other Investment Document or under Applicable Law, the right to exercise
     such Prohibited Transfer Put (as such term is defined below) and, if so
     exercised, the Principal Shareholder shall be bound to perform its
     obligations under this Section 3.9.

                                      -9-

<PAGE>

          (b)  In the event of a Prohibited Transfer, LLCP shall have the right
     to sell to such Principal Shareholder, and such Principal Shareholder shall
     be obligated to purchase (the "Prohibited Transfer Put"), the type and
     number of shares of Capital Stock of the Company equal to the number of
     shares LLCP would have been entitled to transfer to the purchaser under
     Section 3.4 had the Prohibited Transfer been effected pursuant to and in
     compliance with the terms of Sections 3.1 through 3.6. Such sale shall be
     made on the following terms and conditions:

               (i)   The price per share at which shares are to be sold to such
          Principal Shareholder shall be equal to the price per share paid by
          the purchaser to such Principal Shareholder in the Prohibited
          Transfer. Such Principal Shareholder shall also reimburse LLCP for any
          and all fees and expenses, including attorneys, accountants and other
          expenses, incurred pursuant to the exercise or attempted exercise of
          LLCP's rights under Section 3;

               (ii)  Within thirty (30) days after the later of the dates on
          which LLCP (a) received notice of the Prohibited Transfer or (b)
          otherwise became aware of the Prohibited Transfer, LLCP shall, if
          exercising the Prohibited Transfer Put, deliver to such Principal
          Shareholder the certificate or certificates representing the shares to
          be sold, each certificate to be properly endorsed for transfer;

               (iii) Such Principal Shareholder shall, upon receipt of the
          certificate or certificates representing the shares to be sold by
          LLCP, pay the aggregate purchase price therefor and the amount of
          reimbursable fees and expenses, as specified in Section 3.9(b)(i), by
          wire transfer in immediately available funds; and

               (iv)  Notwithstanding the foregoing, any attempt by any Principal
          Shareholder to transfer any Co-Sale Shares in violation of Section 3
          shall be deemed a material breach of this Agreement and, to the extent
          permitted by Applicable Law, be void, and the Company agrees that it
          will not effect such a transfer, nor will it treat any alleged
          transferee as the holder of such shares, without the written consent
          of LLCP.

     3.10 Termination. The rights granted to LLCP under this Section 3 shall
expire on the earlier to occur of (a) November 24, 2009, and (b) the date upon
which the number of shares of Common Stock (calculated on an "as-if-converted"
basis) owned or held, directly or indirectly, by LLCP at any time is less than
five percent (5.0%) of the number of shares of Common Stock on a Fully Diluted
Basis at such time.

4.   RIGHT OF FIRST REFUSAL.

     4.1  The Company hereby grants to LLCP the right to purchase up to the LLCP
Pro Rata Share (as such term is defined below) of any New Securities (as such
term is defined below) which the Company may from time to time propose to issue
or sell, and the Company shall not issue or sell any New Securities without
first complying with the

                                      -10-

<PAGE>

provisions of this Section 4. LLCP's right to purchase shall be at the same
price applicable to such issuance or sale of New Securities. The term "LLCP Pro
Rata Share" shall be equal to a percentage, calculated immediately prior to the
issuance of any New Securities, based upon a fraction, (a) the numerator of
which is equal to the (i) total number of shares of Common Stock beneficially
owned, directly or indirectly, by LLCP immediately prior to such issuance, plus
(ii) the total number of shares of Common Stock issuable upon exercise or
conversion of any Option Rights held directly or indirectly, by LLCP immediately
prior to such issuance, and (b) the denominator of which is the sum of (i) the
total number of shares of Common Stock issued and outstanding (calculated on an
"as-if-converted" basis) immediately prior to such issuance, plus (ii) the total
number of shares of Common Stock issuable upon exercise or conversion of any
Option Rights held directly or indirectly, by LLCP immediately prior to such
issuance.

     4.2  The term "New Securities" shall mean any Capital Stock (including
Common Stock and preferred stock) of the Company whether now authorized or not,
and any Option Rights of the Company; provided, however, that the term New
Securities does not include (a) any equity securities issued in a public
offering pursuant to an effective registration statement under the Securities
Act with an aggregate offering price to the public of at least $10,000,000,
provided that such equity securities are listed at the time of issuance on a
recognized national securities exchange or on the NASDAQ National Market, (b)
any Option Rights to purchase shares of Common Stock granted by the Company,
whether prior to or after the date hereof, to directors, officers or key
employees of the Company or any of its Affiliates under any Company Stock Plan
existing on the date hereof, and shares of Common Stock issuable upon exercise
of such Option Rights.

     4.3  If the Company proposes from time to time to undertake any issuance of
New Securities, it shall give LLCP written notice (an "Issuance Notice") of such
proposed issuance, describing the type of New Securities, the proposed offer
price and the general terms upon which the Company proposes to issue the same.
LLCP shall have thirty (30) days after its receipt of the Issuance Notice to
decide whether it wishes to purchase up to the LLCP Pro Rata Share of the New
Securities for the price and upon the terms specified in the Issuance Notice by
furnishing written notice to the Company (a "Purchase Notice") indicating the
number of New Securities to be purchased by LLCP. To the extent that LLCP shall
have timely furnished a Purchase Notice to the Company, the Company shall, at
the closing of the issuance of such New Securities, sell to LLCP such number of
New Securities as LLCP shall have notified the Company that it intends to
purchase in the applicable Purchase Notice on the terms set forth in the
Issuance Notice.

     4.4  The rights granted to LLCP under this Section 4 shall expire on the
earlier to occur of (a) November 24, 2009, and (b) the date upon which the
number of shares of Common Stock (calculated on an "as-if-converted" basis)
owned or held, directly or indirectly, by LLCP at any time is less than five
percent (5.0%) of the number of shares of Common Stock on a Fully Diluted Basis
at such time.

5.   CERTAIN ISSUANCES OF OPTION RIGHTS; COMPANY STOCK PLANS.

     5.1  The Board (or any compensation committee thereof) shall not grant any
Option Rights of the Company to directors, officers, consultants and key
employees of the

                                      -11-

<PAGE>

Company or of any Affiliate of the Company unless (a) such grant is made under
any Company Stock Plan existing on the date of grant at an exercise price per
share that is not less than fair market value on the date of grant, and (b) such
grant has been duly approved (i) in the case of a grant to any officer (other
than a senior executive officer) or employee of the Company who is not a member
of the Board, by a majority vote of the Board, and (ii) in the case of any grant
to a senior executive officer, a member of the Board or a consultant, by the
unanimous vote (or written consent) of the disinterested members of the Board.

     5.2  The Company shall not at any time amend, supplement or otherwise
modify any Company Stock Plan existing at such time, or adopt or approve any
stock option or stock purchase plan, agreement or arrangement after the date
hereof, without the prior affirmative vote or written consent of the
shareholders of the Company (including the prior affirmative vote or written
consent of LLCP).

6.   CERTAIN ANTI-DILUTION PROTECTION.

     6.1  The Company acknowledges and covenants with the Purchaser that the
number of shares of Capital Stock of the Company beneficially owned by LLCP on a
Fully Diluted Basis (including after giving effect to the shares of Capital
Stock of the Company reserved or to be reserved for issuance under any Company
Stock Plan immediately following the Spin-Off shall represent not less than
24.0% of the total number of shares of Capital Stock of the Company on a Fully
Diluted Basis at such time. In the event that the number of shares of Capital
Stock of the Company beneficially owned by LLCP on a Fully Diluted Basis
immediately following the Spin-Off equals more than 24.0% of the total number of
shares of Capital Stock of the Company on a Fully Diluted Basis immediately
following the Spin-Off, LLCP shall, at the request of the Company, surrender to
the Company a number of shares of Common Stock such that the number of shares of
Capital Stock of the Company beneficially owned by LLCP immediately following
the Spin-Off equals not less than 24.0% of the total number of shares of Capital
Stock of the Company on a Fully Diluted Basis immediately following the
Spin-Off. In the event that the number of shares of Capital Stock of the Company
beneficially owned by LLCP on a Fully Diluted Basis immediately following the
Spin-Off equals less than 24.0% of the total number of shares of Capital Stock
of the Company on a Fully Diluted Basis immediately following the Spin-Off, the
Company agrees to issue to LLCP, at no additional cost to LLCP, a number of
additional shares of Common Stock such that, when added to the number of shares
of Capital Stock of the Company beneficially owned by LLCP on a Fully Diluted
Basis immediately following the Spin-Off, LLCP would own not less than 24.0% of
the total number of shares of Capital Stock of the Company on a Fully Diluted
Basis immediately following the Spin-Off.

     6.2  If, at the time LLCP owns or holds any Warrant Shares, any event
occurs which would have resulted in an adjustment to the exercise price of the
Warrant Shares, or the number of Warrant Shares issuable to LLCP, had the
Warrant not been exercised (a "Warrant Dilutive Issuance"), the Company shall
issue to LLCP on the effective date of such Warrant Dilutive Issuance, without
further payment of any kind, a number of additional shares of Common Stock equal
to the difference between (a) the number of shares of Common Stock which would
have been issuable upon exercise of the Warrant had the

                                      -12-

<PAGE>

Warrant not been exercised in any part, after giving effect to such Dilutive
Issuance, and (b) the number of Warrant Shares issued to LLCP upon exercise of
the Warrant.

7.   MISCELLANEOUS.

     7.1  Legends. All certificates representing shares of capital stock of the
Company now owned or held or hereafter acquired by any Principal Shareholder
shall have stamped or endorsed thereon a legend substantially in the following
form (in addition to any legends required under applicable state securities
laws):

          THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES
          REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND CONDITIONS

     7.2  Stock Transfer Records. The Company shall make appropriate notations
in its stock transfer records of the restrictions on transfer provided for in
this Agreement and shall not record any transfers of capital stock of the
Company not made in strict compliance with the terms of this Agreement. The
Company acknowledges that any such transfer shall constitute an Event of Default
under Section 10.1 of the Securities Purchase Agreement.

     7.3  Assignments. The rights and obligations of LLCP under this Agreement
shall be freely assignable or delegable, as the case may be, in connection with
any transfer of the Warrant Shares, in whole or in part; provided, however, that
the rights of LLCP under Section 1 may not be assigned except in connection with
any transfer of Warrant Shares to an Affiliate of LLCP. Any assignee of such
rights shall be entitled to all of the benefits of this Agreement as if such
assignee were an original party hereto. The rights and obligations of the
Company and the Principal Shareholders may not be assigned or delegated, as the
case may be, without LLCP's prior written consent, except that any Principal
Shareholder may, without LLCP's consent, assign its rights, but not delegate its
obligations, to any transferee under Section 3.1(c).

     7.4  Entire Agreement. This Agreement represents the final agreement among
the parties with respect to the matters set forth herein and supersedes any
prior oral or written, or any contemporaneous oral, agreements or understandings

Agreement a legal, valid, and enforceable provision as similar in terms to the
illegal, invalid, or unenforceable provision as may be possible.

     7.7  Counterparts. This Agreement may be executed in two or more
counterparts and by facsimile transmission, each of which shall be an original,
but all of which together shall constitute one instrument.

     7.8  Construction and Interpretation. The rules of construction set forth

the construction and interpretation of this Agreement.

     7.9  Amendments; Successors and Assigns. This Agreement may be amended,
supplemented or otherwise modified by a writing signed by the Company and LLCP
only; provided, however, that no amendment, supplement or other modification may

amendment or other modification effected in accordance with this Section 7.9
shall be binding upon, and inure to the benefit of, the Company, the Principal
Shareholders, LLCP and their respective successors and permitted assigns.

     7.10 Remedies. In the event that the Company or any Principal Shareholder
fails to observe or perform any covenant or agreement to be observed or
performed by it or him under this Agreement, LLCP may proceed to protect and
enforce its rights by suit in equity or action at law, whether for specific
performance of any term contained in this Agreement or for an injunction against
the breach of any such term or in aid of the exercise of any power granted in
this Agreement or to enforce any other legal or equitable right of LLCP, or to
take any one or more of such actions. The Company agrees to pay all fees, costs,
and expenses, including fees and expenses of attorneys, accountants and other
experts retained by LLCP, and all fees, costs and expenses of appeals incurred
or expended by LLCP in connection with the enforcement of this Agreement or the
collection of any sums due hereunder, whether or not suit is commenced. None of
the rights, powers or remedies conferred under this Agreement shall be mutually
exclusive, and each such right, power or remedy shall be cumulative and in
addition to any other right, power or remedy whether conferred by this Agreement
or now or hereafter available at law, in equity, by statute or otherwise.

     7.11 Representations by Principal Shareholders. Each Principal Shareholder
hereby represents and warrants to LLCP that (a) he has carefully read this
Agreement and has had sufficient time and opportunity to consider its terms and

Shareholder's assets are bound or any Applicable Laws and (e) he has delivered
to LLCP a duly executed Spousal Consent, substantially in the form of Exhibit A.

     7.12 Governing Law. In all respects, including all matters of construction,
validity and performance, this Agreement and the rights and obligations arising

     7.14 Amendment and Restatement. Effective on and as of the Effective Date,
this Agreement shall supersede the Original Investor Rights Agreement insofar as
the two are inconsistent. However, the execution and delivery of this Agreement
shall not excuse, or constitute a waiver of, any Defaults or Events of Default
under the Original Investor Rights Agreement, it being understood that this
Agreement is not a termination of the Original Investor Rights Agreement, but is
a modification (and, as modified, a continuation) of the Original Investor
Rights Agreement. The Company acknowledges and agrees that the Original Investor
Rights Agreement, as amended and restated hereby, is affirmed in all respects.

     7.15 WAIVER OF TRIAL BY JURY. EACH PARTY HEREBY KNOWINGLY, INTENTIONALLY
