         ------------------------------
and warrants to the LLC and to the other Member as follows:

          (a) Authorization. Such Member is a corporation, duly organized,
              -------------
validly existing, and in good standing under the law of its state of
organization, and it has full power and authority to execute and enter into this
Agreement and to perform its obligations hereunder, and all actions necessary
for the due authorization, execution, delivery and performance by such Member of
this Agreement have been duly taken;

          (b) Compliance with Other Instruments. Such Member's authorization,
              ---------------------------------
execution, delivery, and performance of this Agreement do not conflict with any
other agreement or arrangement to which such Member is a party or by which it is
bound;

          (c) Purchase Entirely for Own Account. Such Member is acquiring its
              ---------------------------------
Membership Interest in the LLC for such Member's own account for investment
purposes only and not with a view to or for the resale, distribution,
subdivision or fractionalization thereof and has no contract understanding,
undertaking, agreement or arrangement of any kind with any Person to sell,
transfer or pledge to any Person such Membership Interest or any part thereof
nor does such Member have any plans to enter into any such agreement;

          (d) Investment Experience. By reason of its business or financial
              ---------------------
experience, such Member has the capacity to protect its own interests in
connection with the transactions contemplated hereunder, is able to bear the
risks of an investment in the LLC, and at the present time could afford a
complete loss of such investment;

          (e) Disclosure of Information. Such Member is aware of the LLC's
              -------------------------

              ---------------------------------
laws apply to the Membership Interests, such Member acknowledges that the
Membership Interests have not been registered under the Securities Act or any
state securities laws, inasmuch as they are being acquired in a transaction not
involving a public offering, and under such laws, may not be resold or
transferred by such Member without appropriate registration or the availability
of an exemption from such requirements. In this connection, such Member
represents that it is familiar with SEC Rule 144, as presently in effect, and
understands the resale limitations imposed thereby and by the Securities Act.

     3.3 Resignation or Withdrawal of a Member. Except as specifically provided
         -------------------------------------

         ------------------------------------------------------------------
Neither Member may transfer, sell, encumber, mortgage, assign or otherwise
dispose of any portion of its Membership Interest except on such terms,
including any amendment hereto, as the other Member may agree in writing. Any
purported transfer, sale, encumbrance, mortgage, assignment, or disposition of a
Membership Interest in contravention of this Section 3.4 will be void and of no
effect to, on or against the LLC, any Member, any creditor of the LLC or any
claimant against the LLC. Notwithstanding any other provision of this Agreement,
no Person will be admitted as a Substitute Member and admitted to all the rights
of such Member who assigned its respective Membership Interest, without the
prior written approval of both Members. If so admitted, the Substitute Member
will have all the rights and powers of, and will be subject to all the
restrictions and liabilities of, such Member who originally assigned the
Membership Interest. The admission of a Substitute Member will not release
either Member who previously assigned its Membership Interest from any liability
of such assigning Member to the LLC that may have existed before such
substitution. Consents required hereunder may be given in advance of any
transfer by any writing signed by a Member. A Substitute Member, upon admission
to the LLC, will be a Member for all purposes thereafter.

Neither the Management Committee nor any officer of the LLC will be responsible
to any Member because of a loss of investments or a loss in operations, unless
the loss is the result of fraud, deceit or a wrongful taking by the Management
Committee or any member of the Management Committee, or such officer proven as
set forth in this Section 7.8. Absent fraud upon the LLC or either or both
members, or violation of the confidentiality provisions of any employee or
consultant invention assignment and confidentiality agreement between such
individual and the LLC, and except as otherwise provided in any written
agreement between the next described individuals and either Member, and except
as to otherwise unlawful conduct, neither any member of the Membership
Committee, nor any officer of the LLC, will incur liability to the LLC or to any
of the Members as a result of engaging in any other business or venture.

     7.9 Resignation of Officers; Removal. Any officer of the LLC may resign at
         --------------------------------
any time by giving written notice thereof to each Member and to the Management
Committee. Any officer may be removed and replaced, with or without cause, upon
the decision of the Management Committee. In the event the Chief Operating
Officer, Treasurer or Secretary resigns or is removed, a new Chief Operating
Officer, Treasurer or Secretary, as applicable, shall be appointed pursuant to
Section 7.1.

                                 ARTICLE VIII
                             ACCOUNTING AND RECORDS
                             ----------------------

     8.1 Distributions.
         -------------

          (a) Dissolution Event. Upon the occurrence of a Dissolution Event, if
              -----------------
the LLC is not liquidated, any Member may request, subject to applicable law, an
in-kind distribution allocable to his Capital Account.

          (b) Current Distributions. All cash of the LLC derived from its
              ---------------------
business activities (other than from the proceeds of any loan to the LLC) may be
distributed at such times and in such amounts as the Management Committee shall
determine in its sole discretion. All distributions of cash pursuant to this
Section 8.1(b) shall be distributed to the Members in proportion to their
relative Percentage Interests.

          (c) Liquidating Distributions. After the payment of the debts and
              -------------------------
liabilities of the LLC, as provided in Section 12.4 hereof, any property or
assets of the LLC, including proceeds from the liquidation thereof, remaining
upon the dissolution and liquidation of the LLC shall be distributed among the
Members in an amount equal to each Member's Capital Account, as adjusted to
reflect gains and losses realized in the process of liquidation. Such
distributions shall be made after allocating all items of Net Profit or Net Loss
to the Members as provided in this Agreement.

          (d) Withholding.
              -----------

              (i) The LLC shall seek to qualify for exemptions from any
provision of the Code or any provision of state, local, or foreign tax law that
would otherwise require the

                                    - 18 -

<PAGE>

LLC to withhold amounts from payment or distributions to the Members. If the
LLC does not obtain any such exemption, the LLC is authorized to withhold from
any payment or distribution to any Member any amounts that are required to be
withheld pursuant to the Code or any provision of any state, local, or foreign
tax law that is binding on the LLC.

              (ii)  Any amount withheld with respect to any payment or
distribution to any Member shall be offset against the amount of the payment or
distribution to which the Member would otherwise be entitled. If the Code or any
provision of any state, local, or foreign tax law that is binding on the LLC
requires that the LLC remit to any taxing authority any withholding tax with
respect to, or for the account of, any Member in its capacity as a Member, the
Management Committee shall, to the extent that LLC funds are available therefor,
cause the Company to remit the full required amount of such withholding tax to
the taxing authority and shall notify such Member in writing of its obligation
to pay to the LLC such withholding tax to the extent it exceeds the amount of
any payment or distribution to which such Member would otherwise then be
entitled. Each Member shall pay to the LLC, within five business days after its
receipt of written notice from the Management Committee that withholding is
required with respect to such Member, any amounts required to be remitted by the
LLC to any taxing authority with respect to such Member that are in excess of
the amount of any payment or distribution to which such member would otherwise
be entitled. If the LLC is required to remit any withholding tax with respect
to, or for the account of, any Member prior to the LLC's receipt of any payment
required to be made by such Member pursuant to the preceding sentence, the
amount of the payment required to be made by such Member shall be treated as a
loan (the "Withholding Advance") from the LLC to the Member, which shall accrue
           --------------------
interest until paid at a rate of fifteen percent per year, compounded
semi-annually.

              (iii) To the extent it has not previously been paid by the Member
in cash, any Withholding Advance made to a Member and any interest accrued
thereon shall be credited against, and shall be offset by, the amount of any
later payment or distribution to which the Member would otherwise be entitled,
with any credit for accrued and unpaid interest as of the date such payment or
distribution would otherwise have been made being applied before any credit for
the amount of the Withholding Advance. Any Withholding Advance made to a Member
and any interest accrued thereon, to the extent it has not previously been paid
by the Member in cash or fully credited against payments or distributions to
which the Member would otherwise be entitled, shall be paid by the Member to the
LLC upon the earliest of (A) the dissolution of the LLC, (B) the date on which
the Member ceases to be a Member of the LLC, or (C) demand for payment by the
Management Committee.

     8.2 Allocations of Net Profit and Net Loss.
         --------------------------------------

          (a) Allocation of Net Profit. Except as provided elsewhere in this
              ------------------------
Section 8.2, until the occurrence of a Dissolution Event, as of the end of each
Fiscal Year (or other period for which Net Profit or Net Loss was calculated),
Net Profit (if any) shall be allocated to the Capital Accounts of the Members in
proportion to their Percentage Interests.

                                    - 19 -

<PAGE>

          (b) Allocation of Net Loss. Except as provided elsewhere in this
              ----------------------
Agreement, as of the end of each Fiscal Year (or other period for which Net
Profit or Net Loss was calculated), the Net Loss (if any) for such period shall
be allocated to the Capital Accounts of the Members in accordance with their
Percentage Interests.

          (c) Disaggregation. In making allocations of Net Profit or Net Loss
              --------------
pursuant to this ARTICLE VIII, the Management Committee is authorized to
separate these aggregate amounts into their components of items of gross income,
gain, loss or deduction, and allocate such components separately (i. e.,
allocate items of income and gain as Net Gain, and items of loss or deduction as
Net Loss) in order to further the intent of the provisions of the Agreement.

     8.3 Tax Allocations.
         ---------------

          (a) Items of income, deduction, gain, loss, or credit of the LLC that
are recognized for income tax purposes shall be allocated among the Members in
such manner as to reflect equitably the amounts credited to or debited against
each member's Capital Account (or which will be so credited and debited),
whether in such year, in prior years, or in subsequent years. The LLC shall
establish and maintain records that indicate the extent to which the Capital
Account of each Member, as of the last day of each Fiscal Year, includes amounts
that have and have not been reflected in the taxable income of such Member. In a
manner determined by the Management Committee to be feasible and equitable,
taxable income and gain in each Fiscal Year shall be allocated among the Members
whose Capital Accounts have been allocated the related credits, and items of
deduction, loss, and credit in each Fiscal Year shall be allocated among the
Members whose Capital Accounts have been allocated the related debits.

          (b) In performing the allocations under Section 8.3(a), the following
rules shall apply unless manifestly unreasonable:

              (i)   Items of income and gain of the LLC shall be allocated to
the Members in a manner that complies with the gain charge-back requirements of
Treasury Regulations Section 1.704-2(f) and 1.704-2(i)(4).

              (ii)  If any Member unexpectedly receives any adjustments,
allocations, or distributions described in Regulations Section
1.704-l(b)(2)(ii)(d)(4), 1.704-l(b)(2)(ii)(d)(5), or 1.704-l(b)(2)(ii)(d)(6),
items of LLC gross income and gain shall be specially allocated to such Member
for tax purposes in an amount and manner sufficient to eliminate as quickly as
possible any deficit balance created by such adjustments, allocations, or
distributions in the Member's capital account maintained for tax purposes. Any
special allocation under this Section 8.3(b) shall be taken into account in
computing subsequent allocations of income, deduction, gain, loss, and credit so
that the net amount of allocations of income, deduction, gain, loss, and credit
shall, to the extent possible, be equal to the net amount that would have been
allocated if the unexpected adjustment, allocation, or distribution had not
occurred.

              (iii) If the admission of a Member results in any compensation
income to such Member and as a result the LLC receives a deduction for tax
purposes, such deduction shall be specially allocated to such Member.

                                    - 20 -

<PAGE>

              (iv)  The LLC shall take into account the allocations in Sections
8.3(a) and 8.3(b)(i) and (ii) (the "Regulatory Allocations") in computing
                                    ---------------------
subsequent allocations pursuant to Section 8.3 so that the net amount of any
items so allocated and all other items allocated to each Member pursuant to this
Section 8.3 shall, to the extent possible, be equal to the amount that would
have been allocated to each Member had the Regulatory Allocations not been in
this Agreement.

          (c) For purposes of determining the tax items allocable to any period,
such items shall be determined on a daily basis, as determined by the Management
Committee using any permissible method under Code Section 706 and the
Regulations thereunder.

          (d) In accordance with Code Section 704(b) and Code Section 704(c) and
the Regulations thereunder, income, gain, loss, and deduction with respect to
any property contributed to the capital of the LLC or revalued by the LLC shall,
solely for tax purposes, be allocated among the Members so as to take account of
any variation between the adjusted basis of such property to the LLC for federal
income tax purposes and its value as reflected on the books of the LLC. Any
elections or other decisions relating to such allocations shall be made by the
Management Committee in any manner that reasonably reflects the intent of this
Agreement.

fraudulent in preparation thereof, will be fully protected in relying in good
faith upon the records and books of account of the LLC and upon such
information, opinions, reports or statements presented to the LLC by its Tax
Matters Member, any of its Members, officers, employees, or by any other person,
as to matters the Tax Matters Member or Members reasonably believes are within
such other person's professional or expert competence and who has been selected
with reasonable care

                                    - 21 -

income tax returns.

         ------------------

The Tax Matters Member (or the other Member if it receives such notification)
will provide notice to the other Member, as provided in Code Section 6223(g) of
any administrative or judicial proceeding for the adjustment of LLC items. The
Tax Matters Member will ensure that the other Member is a notice partner as
provided in Code Section 6223(b). The Tax Matters Member may hire tax counsel
and accountants, at the expense of the LLC, in connection with any
representation of the LLC.

     9.6 Annual Reports. The LLC will deliver to each Member and to each Person
         --------------

part of the Fiscal Year in question within 90 days after the end of each Fiscal

requirement of an audit at any time and for any reason. The Treasurer will be

                  INDEMNIFICATION AND LIMITATION OF LIABILITY
                  -------------------------------------------

     11.1 Indemnification.
          ---------------

          (a) Indemnification by LLC of Certain Indemnitees. To the fullest
extent permitted by the Act and by law, the LLC, in accordance with this Section
11.1, will indemnify and hold harmless the Management Committee, each member of
the Management Committee, each Member and its Affiliates, and the partners,
members, stockholders, as relevant, of each Member and its Affiliates, and the
controlling persons, officers, directors or equivalents, and employees and
agents of each Member or Affiliate, as applicable, (collectively, the
"Indemnitees"), against any and all Damages arising from any and all claims,
 -----------
demands, actions, suits or proceedings (civil, criminal, administrative or
investigative) in which the Indemnitee may be involved, as a party or otherwise,
by reason of the Indemnitee's management of, or involvement in, the affairs of
the LLC, or rendering of advice or consultation with respect thereto, or which
otherwise relate to the LLC, its properties, business or affairs, if such
Indemnitee acted in good faith and in a manner such Indemnitee reasonably
believed to be in, or not opposed to, the best interests of the LLC, and, with
respect to any criminal proceeding, had no reasonable cause to believe the
conduct of such Indemnitee was unlawful. The termination of a proceeding by
judgment, order, settlement, conviction or upon a plea of nolo contendere, or
                                                          ---- ----------
its equivalent, will not, of itself, create a presumption that such Indemnitee
did not act in good faith and in a manner which such Indemnitee reasonably
believed to be in, or not opposed to, the best interests of the LLC or that such
Indemnitee had reasonable cause to believe that such Indemnitee's conduct was
unlawful (unless there has been a final adjudication in the proceeding that such
Indemnitee did not act in good faith and in a manner which such Indemnitee
reasonably believed to be in or not opposed to the best interests of the LLC, or
that such Indemnitee did have reasonable cause to believe that such Indemnitee's
conduct was unlawful).

          (b) Certain Other Indemnification by the LLC. The LLC may also
              ----------------------------------------
indemnify, as an Indemnitee hereunder, any individual who was or is a party or
is threatened to be made a party to any threatened, pending, or completed action
by or in the right of the LLC to procure a judgment in its favor by reason of
the fact that such individual is or was a member of the Management Committee, or
an officer, employee, consultant or agent of the LLC, against

                                    - 24 -

<PAGE>

expenses actually or reasonably incurred by such individual in connection with
the defense or settlement of such action, if such individual acted in good faith
and in a manner such individual reasonably believed to be in, or not opposed to,
the best interests of the LLC, except that indemnification will be made in
respect of any claim, issue or matter as to which such individual will have been
adjudged to be liable for misconduct in the performance of the individual's duty
to the LLC only to the extent that the court in which such action or suit was
brought, or another court of appropriate jurisdiction, determines upon
application that, despite the adjudication of liability, but in view of all
circumstances of the case, such individual is fairly and reasonably entitled to
indemnity for such expenses which such court will deem proper. To the extent
that such individual has been successful on the merits or otherwise in defense
of any proceedings referred to herein, or in defense of any claim, issue or
matter therein, such individual will be indemnified by the LLC against expenses
actually and reasonably incurred by such individual in connection therewith.
Notwithstanding the foregoing, no individual will be entitled to indemnification
hereunder for any conduct arising from the gross negligence or willful
misconduct of such individual or reckless disregard in the performance by such
individual of such individual's duties under this Agreement or duties to the
LLC.

          (c) Payment or Advancement of Certain Expenses. Expenses (including
              ------------------------------------------
reasonable fees and costs of attorneys) incurred in defending any proceeding
under Sections 11.1(a) or (b) hereof may be paid by the LLC in advance of the
final disposition of such proceeding upon receipt of an undertaking by or on
behalf of the Indemnitee or Person to repay such amount if it will ultimately be
determined that the Indemnitee or Person is not entitled to be indemnified by
the LLC as authorized hereunder.

          (d) No Exclusivity. The indemnification provided by this Section 11.1
              --------------
will not be deemed to be exclusive of any other rights to which any Person may
be entitled under any agreement, or as a matter of law, or otherwise, both as to
action in a Person's official capacity and to action in another capacity.

     11.2 Liability for Finder's or Broker's Fees. Each Member will be
          ---------------------------------------
responsible for paying any finder's or broker's fee and any other Damages owed
any third party that such Member incurs or which is claimed by such third party
against the other Member and/or LLC, based directly or indirectly on the
negotiation of, or the entry by the parties hereto into, this Agreement, and
will indemnify the LLC and the other Member, and the other Indemnitees, against
any obligation to pay any such fee.

     11.3 Liability in Event of Default. In the event of an Event of Default,
          -----------------------------
the Defaulting Member will be liable to the LLC and to the Non-Defaulting
Member, and to such other Indemnitees as are relevant, for any and all Damages
suffered or incurred by the LLC or the Non-Defaulting Member or such other
Indemnitee(s) as a result of such Event of Default.

     11.4 Limitation of Liability. Each Member's liability under this ARTICLE XI
          -----------------------
will be limited as set forth in the Act and other applicable law.
Notwithstanding anything to the contrary herein contained (a) the debts,
obligations and liabilities of the LLC will be solely the debts, obligations and
liabilities of the LLC; and no Member or member of the Management Committee

                                    - 25 -

<PAGE>

or officer of the LLC or any other Indemnitee will be obligated personally for
any such debt, obligation or liability of the LLC solely by reason of such
Person, or such Person's related Indemnitee, being a Member or member of the
Management Committee or officer of the LLC, and the LLC will hold such Person,
or such Person's related Indemnitee, harmless from any such debt, obligation or
liability, and (b) as to any Member who has made a Capital Contribution to the
LLC, such Member will not be liable, absent fraud, for any debts or losses of
the LLC beyond the total amount of such Member's Capital Contribution.

of the Members, including any written agreement between the Members, to
terminate and dissolve the LLC; or

              (ii)  Dissolution of LLC By Court Order Or Authority. Any

                    --------------
non-affected Members give written notice to the affected Member (or such
affected Member's trustee or similar third party in the event of Dissolution or
Bankruptcy of the affected Member), with a copy to the Management Committee, of
the non-affected Members' election to terminate and dissolve the LLC, which
notice, to be effective, must be given within 15 days after the non-affected
Members receive written notice from the affected Member (or its trustee or
relevant similar party) as to the occurrence of the relevant event, as provided

in which notice such notifying non-affected Members state that, in the good
faith judgment of such Members, such Force Majeure Event does or could have a
material adverse effect on the business or operations of the LLC and/or of such
non-affected Members.

          (b) Notice of Certain Events. Upon the occurrence of a Dissolution
              ------------------------
Event or a Force Majeure Event as to an affected Member, the affected Member
shall give the non-affected Members and the LLC notice of such an event within
10 days of the occurrence of such event.

     12.2 Authority to Wind Up. The Management Committee will have all necessary
          --------------------
power and authority required to marshal the assets of the LLC, to pay its
creditors, to distribute assets and otherwise wind up the business and affairs
of the LLC. In particular, the Management Committee will have the authority to
continue to conduct the business and affairs of the LLC insofar as such
continued operation remains consistent, in the judgment of the Management
Committee, with the orderly winding up of the LLC.

     12.3 Winding Up and Certificate of Cancellation. The winding up of the LLC
          ------------------------------------------
will be completed when all debts, liabilities and obligations of the LLC have
been paid and discharged or reasonably adequate provision therefor has been
made, and all of the remaining property and assets of the LLC have been
distributed to the Members. Upon the completion of winding up of the LLC, a
Certificate of Cancellation will be filed with the Office of the Secretary of
State of Delaware.

     12.4 Distribution of Assets. Upon dissolution and winding up of the LLC,
          ----------------------
the affairs of the LLC will be wound up and the LLC liquidated by the Management
Committee. Pursuant to such liquidation, and subject to the Right of First
Refusal, the assets of the LLC will be sold, unless the Members will consent to
a distribution in kind of the assets. If the Members do not consent to a
distribution in kind but the Management Committee determines that an immediate
sale would be financially inadvisable, it may defer sale of the LLC assets for a
reasonable time; provided, that the liquidation of the LLC will be completed
within the time required by Treasury Regulations Section 1.704-1(b)(ii)(b)(2).
If any assets are distributed in kind, then they shall be distributed on the
basis of the fair market value thereof as determined by appraisal, and shall be
deemed to have been sold at such fair market value for purposes of the
allocations under ARTICLE VIII hereof. Unless the Members otherwise agree, if
any assets are to be distributed in kind, they will be distributed to the
Members, as tenants-in-common, in undivided interests in proportion to
distributions to which such Members are entitled under this Section 12.4. The
assets of the LLC, whether cash or in kind and including any cash or property
generated through the exercise of the Right of First Refusal, will be
distributed as follows in accordance with the Act, (a) first to creditors of the
LLC in the order of priority provided by law and (b) then to the Members as
provided in Section 8.1(d) hereof. Except as specifically provided otherwise
herein, no Member will have any obligation at any time to repay or restore to
the LLC all or any part of any distribution made to it from the LLC in
accordance with this Section 12.4 or to make any additional contribution of
capital to the LLC. The LLC will terminate when all of its assets have been sold
and/or distributed and all of its affairs have been wound up.

     12.5 Right of First Refusal Regarding Intellectual Property Rights of the
          --------------------------------------------------------------------
LLC.
---

          (a) Upon the dissolution and winding up of the LLC, Embarcadero shall
have a right of first refusal (the "Right of First Refusal") to purchase any or
                                    ----------------------
all intellectual property rights owned by the LLC (the "Intellectual Property")
                                                        ---------------------
at the fair market value of such intellectual property.

          (b) Embarcadero shall exercise its Right of First Refusal within 60
days of the occurrence of the event giving rise to the termination and
dissolution of the LLC by giving Aztec and the LLC written notice of its
exercise of such right. Such notice shall include a list of the Intellectual
Property rights for which the Right of First Refusal shall be exercised as well
as the price at which Embarcadero offers to purchase such Intellectual Property.
If Aztec does not agree that the price offered by Embarcadero represents the
fair market value of the Intellectual Property identified by Embarcadero, the
Members shall have 30 days within which to agree on the fair market value. If
the Members cannot agree on the fair market value of such Intellectual Property
the Members shall agree in writing on an Appraiser who shall determine such fair
market value. If the Members cannot agree on an Appraiser within 30 days, then:

              (i)   Selection of an Appraiser by Each Member. Aztec and
                    ----------------------------------------
Embarcadero will, within 30 days after the earlier of the date upon which such
Members agree in writing that they cannot agree on such Appraiser, or such
initial 30 days have expired, select an Appraiser;

              (ii)  Selection by Two Appraisers of Third Appraiser. The
                    ----------------------------------------------
Appraisers selected pursuant to Section 12.5(b)(i) hereof mutually will select a
third Appraiser; and

              (iii) Agreement or Average. The three Appraisers so selected
                    --------------------
mutually will agree on the fair market value of the Intellectual Property
identified by Embarcadero or, absent agreement, the fair market value of such
Intellectual Property will be the average of the values calculated by each
Appraiser;

          (c) The Appraiser(s) shall notify each Member in writing of the
determined fair market value of such Intellectual Property, setting forth in
such writing such bases and conclusions as such Appraiser(s) deem appropriate
and customary therefor.

          (d) Fees and Costs of Appraiser. Each Member will bear the fees and
              ---------------------------
costs of any Appraisers that such Member selects. The fees and costs of any
Appraiser selected jointly by Aztec and Embarcadero, or the costs of a third
Appraiser selected pursuant to Section 12.5(b)(ii) hereof, will be borne
one-half (1/2) by such Member. Each Member will bear its respective internal
costs connected with such appraisal.

other party written notice of any dispute not resolved in the normal course of
business. Within 15 days after delivery of the notice, the receiving party shall
submit to the other a written response. The notice and the response shall
include: (i) a statement of each party's position and a summary of arguments
supporting that position; and (ii) the name and title of the executive who will
represent that party and of any other person who will accompany the executive.
Within 15 days after delivery of the disputing party's notice, the executives of

relating to this Agreement which has not been resolved through negotiation as
provided under Section 13.1 within 60 days of the initiation of such procedure,

arbitrators selecting the third arbitrator. The judgment upon the award rendered
by the arbitrators may be entered by any court having jurisdiction thereof. The
place of arbitration shall be San Francisco, California.

     13.3 Arbitrator Decisions. The arbitrators will decide in accordance with
          --------------------
the terms of this Agreement and will take into account any appropriate trade
usages applicable to the transaction. The arbitrators will state in writing the
reasons upon which the award is based. The arbitrators may allocate the fees and
expenses of arbitration, including the reasonable fees and costs of the
attorneys for the parties among the parties as the arbitrators deem appropriate.
If no allocation of fees is made, the allocation set forth in Section 15.16
below shall apply and arbitration costs and fees shall be borne by the
non-prevailing party.

     13.4 Award of Arbitrators. The award of the arbitrators will be final and
          --------------------
binding upon the parties. Judgment upon the award may be entered in any court

     13.5 Confidentiality. The negotiations pursuant to Section 13.1 and any
          ---------------
arbitration proceedings pursuant to Section 13.2 and terms of any arbitration

and jurisdiction of such courts.

                                  CONFIDENTIALITY
                                  ---------------

     14.1 Obligations of Confidentiality. The provisions of this ARTICLE XIV
          ------------------------------
will apply to all Confidential Information disclosed by one party hereto to one
or more of the other parties hereto, whether prior to or after the Effective
Date, and which is not otherwise the subject of a written nondisclosure
agreement between the relevant parties. Each party hereto (a) will hold the
other parties' Confidential Information in strict confidence, (b) will not
disclose such Confidential Information to any third party and will take all
reasonable steps to prevent such disclosure, which steps will include at least
those taken by such relevant other party to protect such other party's own
confidential information of like kind, and (c) will not use any Confidential
Information of the other party for any purpose except as is necessary to carry
out this Agreement or the Collateral Agreements. Each receiving party may
disclose the disclosing party's Confidential Information to the receiving
party's responsible employees and consultants who have a bona fide need to know,
                                                         ---- ----
but only to the extent necessary to carry out the purposes of the LLC. Each
receiving party will instruct all such employees and consultants not to disclose
such Confidential Information to third parties, including other consultants,
without the prior written permission of the disclosing party.

     14.2 Certain Confidential Information. The existence of this Agreement and
          --------------------------------
its terms, and the existence and terms of the Collateral Agreements are
Confidential Information of each party hereto.

     14.3 Return of Confidential Information. Upon the disclosing party's
          ----------------------------------
request, the receiving party will promptly return to the disclosing party all
tangible items containing or consisting of the disclosing party's Confidential
Information and all copies thereof.

     14.4 No Other Rights. Nothing contained in this Agreement will be construed
          ---------------
as granting any rights to the receiving party, by license or otherwise, to any
of the disclosing party's Confidential Information except as specified in this
Agreement.

     14.5 Acknowledgment. Each Member and the LLC acknowledge that the
          --------------
unauthorized disclosure or use of the disclosing party's Confidential
Information would cause irreparable harm and significant injury to the
disclosing party, the degree of which may be difficult to ascertain.
Accordingly, each Member agrees that the disclosing party will have the right to
seek an immediate injunction enjoining any breach of this Agreement by the
receiving party or its employees or consultants, as well as the right to pursue
any and all other rights and remedies available at law or in equity for such
breach.

        14.6   Disclosure Required by Law. If the receiving party (or an
               --------------------------
Affiliate of the receiving party) is required, whether by oral questions,
interrogatories, requests for information or documents, subpoena, civil
investigative demand or similar process, by any competent government authority,
including pursuant to any applicable rule of any stock exchange,
self-regulatory organization or other government agency, to disclose any
Confidential Information of the disclosing party, the receiving party will
promptly notify the disclosing party in writing, in reasonable detail, of such
request or requirement and will cooperate with the disclosing party in seeking
appropriate protective arrangements requested by the disclosing party. If, in
the absence of a protective order or the receipt of a waiver in writing by the
disclosing party of such protective order, the receiving party (or any of its
Affiliates) is in the written opinion of the receiving party's counsel
compelled to disclose the Confidential Information or else stand liable for
contempt or suffer other censure or significant penalty, the receiving party
(or its Affiliates) may disclose only so much of the Confidential Information
to the party compelling disclosure as is required by law. The receiving party
will exercise (and will cause its Affiliates to exercise) commercially
reasonable best efforts to obtain appropriate protective arrangements or other
reliable assurance that confidential treatment will be accorded to Confidential
Information of the disclosing party in the event of such required disclosure.

        14.7   Exchange Act Disclosures. It is hereby acknowledged that
               ------------------------
Embarcadero is a publicly traded company and as such is subject to certain
reporting requirements under the Exchange Act. It is hereby agreed by the
parties that notwithstanding the provisions of this ARTICLE XIV Embarcadero may
disclose Confidential Information to the extent necessary to comply with its
Exchange Act reporting requirements.

        14.8   Public Announcements. During the term of this Agreement, neither
               --------------------
the LLC nor either Member will (except as may otherwise be required by law or
by the Exchange Act as described in, and subject to the provisions of, Sections
14.6 and 14.7 hereof) issue any press release or other public announcement or
disclosure, with respect to this Agreement or any of the Collateral Agreements,
or any of the transactions contemplated hereby or thereby, nor any material
development relating to any of the foregoing, without the prior approval of the
Management Committee and the written consent of both Members.

        14.9   Survival of Provision. Notwithstanding any other provision of
               ---------------------
this Agreement, the obligations and rights of the parties pursuant to this
ARTICLE XIV shall survive the dissolution of the LLC and any termination of
this Agreement.

                                  -------------

        15.1   Further Assurances. The parties hereto will execute and deliver
               ------------------
any further instruments or documents and perform any additional acts that are
or may become necessary to effectuate and carry on the LLC created by this
Agreement and to carry out the purposes and intent of this Agreement.

and the LLC with respect to the specific subject matter hereof, and, except as
otherwise set forth herein, supersedes and terminates all prior representations,

amendment also will be binding upon the LLC.

               ----------
any of such Member's rights or obligations hereunder without the prior written

Specifications. Embarcadero shall use all reasonable efforts to provide
Developer within thirty (30) days after receipt by Embarcadero of such Optioned
Software with written acceptance thereof, or a statement of defects to be
corrected. Within fifteen (15) days after Developer's receipt of a statement of
defects, Developer shall correct any such defects and return the corrected
Optioned Software for retesting and reevaluation, and Embarcadero shall use all
reasonable efforts to provide to Developer within fifteen (15) days after such
redelivery a written acceptance or another statement of defects. Until
acceptance by Embarcadero, Developer shall continue to attempt to correct the
defects and provide conforming Deliverables in accordance with the above
procedure. If Developer fails to provide Optioned Software that conforms to the
applicable Specifications within sixty (60) days of initial delivery to
Embarcadero, Embarcadero may finally reject the Optioned Software, without
liability, and release the Optioned Software from the Right of First Refusal.

the terms of this Agreement and will take into account any appropriate trade
usages applicable to the transaction. The arbitrators will state in writing the

         ----------
intellectual property of a party for which the parties may seek judicial relief,
shall be subject to the exclusive venue of the state and federal courts within
the Northern District of California and the parties hereby consent to the venue
and jurisdiction of such courts.

                                   ----------
                                 CONFIDENTIALITY
                                 ---------------

     9.1 Scope. The provisions of this Article 9 will apply to all Confidential
         -----
Information disclosed by one party to the other party, whether prior to or after
the Effective Date, and which is not otherwise the subject of a written
nondisclosure agreement between the parties. Each party: (i) will hold the other
parties' Confidential Information in strict confidence; (ii) will not disclose
such Confidential Information to any third party and will take all reasonable
steps to prevent such disclosure, which steps will include at least those taken
by such relevant other party to protect such other party's own confidential
information of like kind; and (iii) will not use any Confidential Information of
the other party for any purpose except as is necessary to carry out this
Agreement. Each receiving party may disclose the disclosing party's Confidential
Information to the receiving party's responsible employees and consultants who
have a bona fide

                                      10

<PAGE>

need to know, but only to the extent necessary to carry out the purposes of this
Agreement. Each receiving party will instruct all such employees and consultants
not to disclose such Confidential Information to third parties, including other
consultants, without the prior written permission of the disclosing party.

     9.2 Return of Confidential Information. Upon the disclosing party's
         -----------------------------------
request, the receiving party will promptly return to the disclosing party all
tangible items containing or consisting of the disclosing party's Confidential
Information and all copies thereof.

     9.3 No Other Rights. Nothing contained in this Agreement will be construed
         ---------------
as granting any rights to the receiving party, by license or otherwise, to any
of the disclosing party's Confidential Information except as specified in this
Agreement.

     9.4 Acknowledgment. Each party acknowledges that the unauthorized
         --------------
disclosure or use of the disclosing party's Confidential Information would cause
irreparable harm and significant injury to the disclosing party, the degree of
which may be difficult to ascertain. Accordingly, the parties agree that the
disclosing party will have the right to seek an immediate injunction enjoining
any breach of this Article 9 by the receiving party or its employees or
consultants, as well as the right to pursue any and all other rights and
remedies available at law or in equity for such breach.

     9.5 Disclosure Required by Law. If the receiving party (or an affiliate of
         --------------------------
the receiving party) is required, whether by oral questions, interrogatories,
requests for information or documents, subpoena, civil investigative demand or
similar process, by any competent government authority, including pursuant to
any applicable rule of any stock exchange, self-regulatory organization or other
government agency, to disclose any Confidential Information of the disclosing
party, the receiving party will promptly notify the disclosing party in writing,
in reasonable detail, of such request or requirement and will cooperate with the
disclosing party in seeking appropriate protective arrangements requested by the
disclosing party. If, in the absence of a protective order or the receipt of a
waiver in writing by the disclosing party of such protective order, the
receiving party (or any of its Affiliates) is in the written opinion of the
receiving party's counsel compelled to disclose the Confidential Information or
else stand liable for contempt or suffer other censure or significant penalty,
the receiving party (or its affiliates) may disclose only so much of the
Confidential Information to the party compelling disclosure as is required by
law. The receiving party will exercise (and will cause its affiliates to
exercise) commercially reasonable best efforts to obtain appropriate protective
arrangements or other reliable assurance that confidential treatment will be
accorded to Confidential Information of the disclosing party in the event of
such required disclosure.

     9.6 Exchange Act Disclosures. It is hereby acknowledged that Embarcadero is
         ------------------------
a publicly traded company and as such is subject to certain reporting
requirements under the Exchange Act. It is hereby agreed by the parties that
notwithstanding the provisions of this Section 9.6, Embarcadero may disclose
Confidential Information to the extent necessary to comply with its Exchange Act
reporting requirements.

             ------------------------------
parties shall attempt in good faith to resolve any dispute arising out of or

             --------------------
with the terms of this Agreement and will take into account any appropriate
trade usages applicable to the transaction. The arbitrators will state in
writing the reasons upon which the award is based. The arbitrators may allocate
the fees and expenses of arbitration, including the reasonable fees and costs
of the attorneys for the parties among the parties as the arbitrators deem
appropriate.  If no allocation of fees is made, the allocation set forth in
Section 11.9 below shall apply and arbitration costs and fees shall be borne by
the non-prevailing party.

         7.4 Award of Arbitrators. The award of the arbitrators will be final
             --------------------
and binding upon the parties. Judgment upon the award may be entered in any
court having jurisdiction. An application may be made to any such court for
judicial acceptance of the award and an order of enforcement.

         7.5 Confidentiality. The negotiations pursuant to Section 8.1 and any
             ---------------
arbitration proceedings pursuant to Section 8.2 and terms of any arbitration
award shall be deemed Confidential Information for the purposes of this
Agreement.

         7.6 Applicable Law; Disclosure. The law of the State of California,
             --------------------------
excluding that body of law known as conflict of laws, will be the applicable
substantive law for all matters except those governed and by federal law, which
will apply to such other matters.

         7.7 Litigation. Any dispute involving the Confidential Information or
             ----------
intellectual property of a party for which the parties may seek judicial relief,
shall be subject to the exclusive venue of the state and federal courts within
the Northern District of California and the parties hereby consent to the venue
and jurisdiction of such courts.

                                  ARTICLE VIII
                                  ------------
                                CONFIDENTIALITY
                                ---------------

         8.1 Scope. The provisions of this Article 8 will apply to all
             -----
Confidential Information disclosed by one party to the other party, whether
prior to or after the Effective Date, and which is not otherwise the subject of
a written nondisclosure agreement between the parties. Each party: (i) will hold
the other parties' Confidential Information in strict confidence; (ii) will not
disclose such Confidential Information to any third party and will take all
reasonable steps to prevent such disclosure, which steps will include at least
those taken by such relevant other party to protect such other party's own
confidential information of like kind; and (iii) will not use any Confidential
Information of the other party for any purpose except as is necessary to carry
out this Agreement. Each receiving party may disclose the disclosing party's
Confidential Information to the receiving party's responsible employees and
consultants who have a bona fide need to know, but only to the extent necessary
to carry out the purposes of this Agreement. Each receiving party will instruct
all such employees and consultants not to disclose such Confidential Information
to third parties, including other consultants, without the prior written
permission of the disclosing party.

         8.2 Return of Confidential Information. Upon the disclosing party's
             ----------------------------------
request, the receiving party will promptly return to the disclosing party all
tangible items containing or consisting of the disclosing party's Confidential
Information and all copies thereof.

         8.3 No Other Rights.  Nothing contained in this Agreement will be
             ---------------
construed as granting any rights to the receiving party, by license or
otherwise, to any of the disclosing party's Confidential Information except as
specified in this Agreement.

         8.4 Acknowledgment. Each party acknowledges that the unauthorized
             --------------
disclosure or use of the disclosing party's Confidential Information would cause
irreparable harm and significant injury to the disclosing party, the degree of
which may be difficult to ascertain. Accordingly, the parties agree that the
disclosing party will have the right to seek an immediate injunction enjoining
any breach of this Article 8 by the receiving party or its employees or
consultants, as well as the right to pursue any and all other rights and
remedies available at law or in equity for such breach.

         8.5 Disclosure Required by Law. If the receiving party (or an affiliate
             --------------------------
of the receiving party) is required, whether by oral questions, interrogatories,
requests for information or documents, subpoena, civil investigative demand or
similar process, by any competent government authority, including pursuant to
any applicable rule of any stock exchange, self-regulatory organization or other
government agency, to disclose any Confidential Information of the disclosing
party, the receiving party will promptly notify the disclosing party in writing,
in reasonable detail, of such request or requirement and will cooperate with the
disclosing party in seeking appropriate protective arrangements requested by the
disclosing party. If, in the absence of a protective order or the receipt of a
waiver in writing by the disclosing party of such protective order, the
receiving party (or any of its affiliates) is in the written opinion of the
receiving party's counsel compelled to disclose the Confidential Information or
else stand liable for contempt or suffer other censure or significant penalty,
the receiving party (or its affiliates) may disclose only so much of the
Confidential Information to the party compelling disclosure as is required by
law. The receiving party will exercise (and will cause its affiliates to
exercise) commercially reasonable best efforts to obtain appropriate protective
arrangements or other reliable assurance that confidential treatment will be
accorded to Confidential Information of the disclosing party in the event of
such required disclosure.

         8.6 Public Announcements. During the term of this Agreement, neither
             --------------------
party hereto will (except as may otherwise be required by law or by the Exchange
Act as described in, and subject to the provisions of, Section 8.5) issue any
press release or other public announcement or disclosure, with respect to this
Agreement, or any of the transactions contemplated hereby, nor any material
development relating to any of the foregoing, without the prior written consent
of the other party.

                (b)      Either party shall have the right to terminate this

breach with thirty (30) days after receiving written notice of the breach from
the other party.

                            OMEGA PROTEIN CORPORATION

                       ANNUAL INCENTIVE COMPENSATION PLAN

                            (Effective April 8, 1998)

1.   Omega Protein Corporation (the "Company") hereby establishes the Annual
     Incentive Compensation Plan, effective April 8, 1998 (the "Plan"), for the
     benefit of eligible employees. The Plan is intended to promote the
     financial interests of the Company and its stockholders by (i) helping the
     Company to retain the services of the participants and by (ii) stimulating
     the efforts of the Participants on behalf of the Company by giving them a
     direct interest in the performance of the Company and by giving suitable
     recognition to their services to the Company.

2.   The following definitions are applicable to the Plan:

     .    Cash Return on Net Operating Invested Capital: The result obtained
          ---------------------------------------------
          when Operating Cash Flow for a Plan Year is divided by Net Operating
          Invested Capital as of the end of such Plan Year.

     .    EBITDA: The earnings of the Company before interest expense, taxes,
          ------
          depreciation and amortization.

     .    Incentive Compensation Fund: The maximum amount, determined as
          ---------------------------
          provided in paragraph 8, available for distribution hereunder.

     .    Net Operating Invested Capital: The result obtained by subtracting the
          ------------------------------
          Company's total current liabilities from the Company's total current
          assets and adding the net book value of the Company's property, plant
          and equipment as of the end of the Plan Year.

     .    Operating Cash Flow: EBITDA.
          -------------------

     .    Plan Year: A fiscal year of the Company.
          ---------

     .    Unit: A unit of participation in the Plan with respect to a particular
          ----
          Plan Year.

3.   The Plan shall be administered by the Board of Directors or the Company
     (the "Board") or the Compensation Committee of the Board of Directors (the
     "Committee"). Subject to the provisions of the Plan, the Committee shall
     have the authority to interpret the Plan and make all determinations
     required pursuant to the Plan.

4.   Participants in the Plan and the number of Units awarded to each
     participant shall be determined by the Committee or, with its approval, by
     the Chief Executive Officer of the Company. Discretion may be exercised
     differently with respect to different Participants in determining the
     number, terms and conditions of Units awarded hereunder; provided that such
     terms and conditions shall be consistent with the provisions of the Plan.

5.   The maximum number of units awarded for any Plan Year to any participant
     shall not exceed one hundred fifty percent (150%) of the participant's
     annual base salary (in dollars) as of the end of the Plan Year.

                                                                               1

6.   The number of Units awarded to any single participant shall not exceed
     600,000 in any single Plan Year.

7.   The Incentive Compensation Fund for any Plan Year shall be an amount equal
     to the sum of the following:

     .    Ten percent (10%) of the increase, if any, in EBITDA for the Plan Year
          over EBITDA for the preceding fiscal year of the Company; and

     .    Five percent (5%) of the Cash Return on Net Operating Invested Capital
          for the Plan Year; and

     .    Such additional amount, if any, as the Committee in its sole
          discretion determines to add to the Incentive Compensation Fund, such
          determination to be based on the financial performance of the Company
          as compared to the projections of financial analysts; and

     .    any amount carried forward from a prior Plan Year.

8.   As soon as possible after the close of each Plan Year, the amount of the
     Incentive Compensation Fund shall be determined. As soon as possible after
     such determination, the Committee shall make distributions, in one lump sum
     payment, for the Plan Year by awarding each participant an amount equal to
     the product of the following: the total amount available in the Incentive
     Compensation Fund for the Plan Year multiplied by a fraction in which the
     numerator equals the Units awarded to the Participant for the Plan Year and
     the denominator equals the total number of Units awarded to all
     Participants for the Plan Year; provided, however, that in no event can any
     distribution be greater than One Dollar ($1.00) per Unit. (For example, if
     the incentive compensation Fund totals $1,000,000.00 and a participant was
     awarded 10,000 Units of 1,200,000 total Units awarded, the bonus to that
     participant would be $1,000,000 x 1/120 or $8,333.33 (83.3 cents per
     Unit)). Any portion of the Incentive Compensation Fund for the Plan Year
     not paid out shall be carried forward and will be available for awards in
     any future Plan Year.

9.   No employee or other person shall have any claim or right to be made to a
     participant under this Plan. The terms and conditions of an award of Units
     shall be communicated in writing to the participant, and such writing,
     rather than to any descriptions made above, shall control. Neither the Plan
     nor any action taken thereunder shall be construed as giving an employee
     any right to be retained in the employ of the Company. No participant shall
     have any lien on any assets of the Company by reason of any award made
     under this Plan.

10.  The Board may amend, suspend or terminate the Plan in whole or in part, but
     it may not affect adversely rights or obligations with respect to awards
     theretofore made.

     IN WITNESS WHEREOF, the Company has executed this Plan on this 8th day of
April, 1998.
