of the Management Committee shall be held not less than once during every

whenever called by one or more Managers. Notice of the time, place and purpose
of each such special meeting shall be sent by facsimile transmission or
electronic mail or be delivered personally or mailed to and received by each
Manager not less than 72 hours before the time at which the meeting is to be

purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened. At the request
of any Manager, any or all Managers may participate telephonically in any
meeting of the Management Committee so long as all persons participating in the
meeting can hear each other, and such participation shall constitute presence in
person at such meeting. Any action required or permitted to be taken at any
meeting of the Management Committee may be taken without a meeting, without
prior notice and without a vote, if a consent in writing (including by
electronic transmission as permitted by Section 18-302 of the Act), setting
forth the action so taken, shall be signed or delivered by all Managers. Such
written (or electronically transmitted) consent shall be filed with the minutes
of proceedings of the Management Committee.

make any contribution of capital to the Company.

in the following adjustments to that Member's Percentage Interest:

              (a) For each One Dollar ($1) that is not contributed by Patriot or
TPL when due pursuant to Section 5.3, one hundred thousandth of a percent
(0.00001%) of the outstanding Percentage Interests of the Company shall be

Member. As an example, if a Member failed to contribute    ***    when due

not previously credited against payments to TPL hereunder) pursuant to Section
4.3 of the Commercialization Agreement; and

                  (v)   Finally, the remaining Gross Cash Proceeds (such
remaining amount, the "Net Cash Proceeds") to the Members according to their
respective Percentage Interests.

                  In the event that funds sufficient to satisfy the payments
required to be made pursuant to subsections (iv)(a) and (iv)(b) above are
unavailable, such payment obligations shall be pari passu, and any unpaid
amounts thereof shall be paid from Gross Cash Proceeds subsequently received by
the Company.

                  (b) Distribution of Company Property. Company property shall
be distributed only pursuant to Article VIII.

                  (c) Withholdings. All amounts withheld pursuant to the Code or
any provisions of state or local tax law with respect to any payment or
distribution to the Members from the Company shall be treated as amounts
distributed to the relevant Members pursuant to this Section 6.1.

         6.2  Allocation of Net Profits.  Subject to the provisions of Sections
6.4 and 6.5, Net Profits for any Fiscal Year or other period shall be allocated
to the Members according to their Percentage Interests.

6.4 and 6.5, Net Losses for any Fiscal Year or other period shall be allocated
to the Members according to their Percentage Interests.

         6.4  General Rules for Allocations. The rules of this Section 6.4 shall
govern all allocations under this Article:

              (a) Except as otherwise provided in this Operating Agreement,
an allocation of Net Profits or Net Losses shall be treated as an allocation
between the Members of the same share of each item of income, gain, loss and
deduction that is taken into account in computing such Net Profits or Net
Losses, as the case may be.

              (b) If any Member is deemed to have received imputed income with
respect to any property licensed or otherwise made available to the Company
pursuant to this Operating Agreement, the corresponding imputed expenses to the
Company arising out of such arrangement shall be specially allocated to such
Member.

              (c) For purposes of determining the Net Profits or Net Losses
allocable to any period, the Net Profits and Net Losses shall be determined on a
daily, monthly or other basis, as determined by the Management Committee using
any permissible method under Section 706 of the Code and the Treasury
Regulations promulgated thereunder.

         6.5  Special Allocations to Capital Accounts.

              (a) Notwithstanding anything to the contrary contained in this
Article 6, if there is a net decrease in Company Minimum Gain or in any Member
Minimum Gain during any taxable year or other period, prior to any other
allocation pursuant hereto, such Member shall be specially allocated items of
income and gain for such year (and, if necessary, subsequent years) in an amount
and manner required by Treasury Regulation Sections 1.704-2(f) or 1.704-2(i)(4).
The items to be so allocated shall be determined in accordance with Treasury
Regulation Section 1.704-2.

              (b) Nonrecourse Deductions for any taxable year or other
period shall be allocated (as nearly as possible) under Treasury Regulation
Section 1.704-2 to the Members, pro rata in proportion to their respective
Percentage Interests.

              (c) Any Member Nonrecourse Deductions for any taxable year or
other period shall be allocated to the Member that made, or guaranteed or is
otherwise liable with respect to the loan to which such Member Nonrecourse
Deductions are attributable in accordance with principles under Treasury
Regulation Section 1.704-2(i).

              (d) Any Member who unexpectedly receives an adjustment,
allocation or distribution described in Treasury Regulation Section
1.704-1(b)(2)(ii)(d)(4), (5) or (6) which causes or increases a negative balance
in his or its Capital Account shall be allocated items of income and gain
sufficient to eliminate such increase or negative balance caused thereby, as
quickly as possible, to the extent required by such Treasury Regulation.

              (e) No allocation or loss or deduction shall be made to any
Member if, as a result of such allocation, such Member would have an Adjusted
Capital Account Deficit. Any such disallowed allocation shall be made to the
Members entitled to receive such allocation under Treasury Regulation Section
1.704 in proportion to their respective Percentage Interests. If losses or
deductions are reallocated under this subsection 6.5(e), subsequent allocations
of income and losses (and items thereof) shall be made so that, to the extent
possible, the net amount allocated under this subsection 6.5(e) equals the
amount that would have been allocated to each Member if no reallocation had
occurred under this subsection 6.5(e).

                                       18
<PAGE>

              (f) For purposes of Section 752 of the Code and the Treasury
Regulations thereunder, excess nonrecourse liabilities (within the meaning of
Treasury Regulations Section 1.752-3(a)(3)) shall be allocated to the Members
pro rata in proportion to their respective Percentage Interests.

              (g) The allocations contained in Sections 6.5(a), 6.5(c), 6.5(d)
and 6.5(e) (the "Regulatory Allocations") are intended to comply with certain
requirements of Treasury Regulation Sections 1.704-1 and 1.704-2. The Regulatory
Allocations shall be taken into account in allocating Net Profit and Net Loss
and other items of income, gain, loss and deduction among the Members so that to
the extent possible, the allocations contained in this Agreement other than the
Regulatory Allocations and the Regulatory Allocations made to each Member shall
equal the net amount that would have been allocated to each Member had the
Regulatory Allocations not occurred. The Management Committee shall take account
of the fact that certain of the Regulatory Allocations will occur at a period in
the future for purposes of applying this Section 6.5(g).

         6.6  Tax Allocations; Section 704(c) of the Code.

              (a) Except as otherwise provided in this Section 6.6, for
income tax purposes, each item of income, gain, loss, and deduction of the
Company shall be allocated among the Members in accordance with the manner in
which the equivalent items of Net Profits and Net Losses were allocated under
the preceding sections of this Article VI.

              (b) In the event the Book Value of a Company asset differs from
its adjusted federal income tax basis, then all allocations of income, gain,
loss and deduction with respect to such asset shall take into account any
variation between the adjusted tax basis of such asset and its Book Value. Such
allocations shall be made under the principles of Sections 704(b) and 704(c) of
the Code and the Treasury Regulations thereunder and are intended to eliminate,
to the extent possible, disparities that otherwise exist between the balances of
the Members' Capital Accounts, as maintained by the Company, and such balances
had the Capital Accounts been maintained in accordance with tax accounting
principles. It is intended, for example, that any taxable gain recognized by the
Company upon the disposition of property contributed by a Member to the Company
shall be allocated to the contributing Member to the extent that the property's
initial Book Value exceeded its adjusted income tax basis on the date of the
contribution, with any excess taxable gain being allocated to the Members
(including the contributing Member) in a manner that coincides with the
corresponding allocation of "book" gain. Any elections, accounting conventions
or other decisions relating to such allocations shall be made by the Management
Committee in a manner that (i) reasonably reflects the purposes and intention of
this Operating Agreement, and (ii) complies with Sections 704(b) and 704(c) of
the Code and the Treasury Regulations thereunder. The Management Committee shall
determine the method set forth in Treasury Regulation Section 1.704-3c to be
used for allocating such terms.

                                       19

         6.7  Tax Matters Member.

         (a)  At such time as it deems necessary, the Management Committee shall
elect the "Tax Matters Member" of the Company for purposes of Section 6231(a)(7)
of the Code. The Tax Matters Member shall have the power to manage and control,
on behalf of the Company, any administrative proceeding at the Company level
with the Internal Revenue Service relating to the determination of any item of
Company income, gain, loss, deduction or credit for federal income tax purposes.

         (b)  The Tax Matters Member shall, within ten (10) days of the receipt
of any notice from the Internal Revenue Service in any administrative proceeding
at the Company level relating to the determination of any Company item of
income, gain, loss, deduction or credit, mail a copy of such notice to the other
Members.

         6.8  Section 754 Election. The Tax Matters Member may, in its
discretion, make, on behalf of the Company, an election in accordance with
Section 754 of the Code so as to adjust the basis of Company property in the
case of a distribution of property within the meaning of Section 734 of the
Code, and in the case of a transfer of a Member's Percentage Interest within the
meaning of Section 743 of the Code. Each Member shall, upon the request of the
Tax Matters Member, furnish such information as the Tax Matters Member shall
deem necessary or appropriate to give effect to such election.

         6.9  Returns and Other Elections. The Chief Financial Officer shall
cause the preparation and timely filing all tax returns required to be filed by
the Company pursuant to the Code and all other tax returns deemed necessary and
required in each jurisdiction in which the Company does business. Copies of
those returns, or pertinent information from the returns, shall be furnished to
the Members within a reasonable time after the end of the Company's fiscal year.
All elections permitted to be made by the Company under federal or state laws
shall be made by the Chief Financial Officer, provided that the Management
Committee may direct the Chief Financial Officer to make or refrain from making
any tax election.

         6.10 Partnership Tax Treatment. The Members expect and intend that the
Company shall be treated as a partnership for all federal and state income tax
purposes, and the Members agree that they will not: (a) take a position on any
federal, state, local or other tax return, or otherwise assert a position,
inconsistent with such expectation and intent; or (b) elect for the Company to
be treated as an association for tax purposes or do any other act or thing which
could cause the Company to be treated as other than a partnership for federal
income tax purposes.

                                    ARTICLE 7
                   INDEMNIFICATION AND LIMITATION OF LIABILITY

         7.1  Indemnification.

              (a) To the fullest extent permitted by the Act and by law, the
Members, Managers, officers and employees of the Company, as well as their
respective Representatives (collectively, "Indemnitees") shall, in accordance
with this Section 7.1, be indemnified, protected, held harmless and defended by
the Company from and against any and all Damages and Liabilities by reason of
their management of, or involvement in, the affairs of the Company, or rendering
of advice or consultation with respect thereto, or which relate to the Company,
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 Company.

                                       20
<PAGE>

              (b) If any Indemnitee shall believe that such Indemnitee is
entitled to indemnification pursuant to this Article 7 in respect of any Damages
or Liabilities, such Indemnitee shall give the Company prompt written notice
thereof. Any such notice shall set forth in reasonable detail and to the extent
then known the basis for such claim for indemnification. The failure of such
Indemnitee to give notice of any claim for indemnification promptly shall not
adversely affect such Indemnitee's right to indemnity hereunder except to the
extent that such failure adversely affects the right of the Company to assert
all reasonable defenses to such claim. Each such claim for indemnity shall
expressly state that the Company shall have only the thirty (30) calendar day
period referred to in the next sentence to dispute or deny such claim. The
Company shall have thirty (30) calendar days following its receipt of such
notice either (y) to acquiesce in such claim and the responsibility to indemnify
the Indemnitee in respect thereof in accordance with the terms of this Article 7
by giving such Indemnitee written notice of such acquiescence or (z) to object
to the claim by giving such Indemnitee written notice of the objection. If the
Company does not object thereto within such thirty (30) calendar day period, the
Company shall be deemed to have acquiesced in such claim and the responsibility
to indemnify the Indemnitee in respect thereof in accordance with the terms of
this Article 7.

              (c) In connection with any claim which may give rise to indemnity
under this Article 7 resulting from or arising out of any claim or Proceeding
against an Indemnitee by a Person that is not a party hereto, the Company may
(unless such Indemnitee elects not to seek indemnity hereunder for such claim),
upon written notice sent at any time to the relevant Indemnitee, assume the
defense of any such claim or Proceeding if the Company with respect to such
claim or Proceeding acknowledges to the Indemnitee the Indemnitee's right to
indemnity pursuant hereto in respect of the entirety of such claim (as such
claim may have been modified through written agreement of the parties or
arbitration hereunder) and provide assurances, reasonably satisfactory to such
Indemnitee, that the Company will be financially able to satisfy such claim in
full if such claim or Proceeding is decided adversely. The Company shall select
counsel reasonably acceptable to such Indemnitee to conduct the defense of such
claim or Proceeding, shall take all steps reasonably necessary in the defense or
settlement thereof and shall at all times diligently and promptly pursue the
resolution thereof. If the Company shall have assumed the defense of any claim
or Proceeding in accordance with this Section 7, the Company shall not (without
the written consent of each Indemnitee) consent to a settlement of, or the entry
of any judgment arising from, any such claim or Proceeding, unless such
settlement or order shall provide for the unconditional release of all
Indemnitees. If the Company has so elected to assume the defense, each
Indemnitee shall be entitled to participate in (but not control) the defense of
any such action, with its own counsel and at its own expense. Each Indemnitee
shall, and shall cause each of its Representatives to, cooperate fully with the
Company in the defense of any claim or Proceeding being defended by the Company
pursuant to this Section 7. If the Company does not assume the defense of any
claim or Proceeding resulting therefrom in accordance with the terms of this
Section 7, such Indemnitee may defend against such claim or Proceeding in such
manner as it may deem appropriate, provided that the Indemnitee may not settle
such claim or Proceeding without the written consent of the Company (which
consent shall not be unreasonably withheld or delayed), and provided further
that the Company shall be obligated to pay Indemnitee's attorneys' fees and
costs promptly as they are incurred in the defense of such claim or Proceeding.

                                       21
<PAGE>

              (d) The indemnification provided by this Section 7.1 shall 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.

              (e) The Management Committee shall have power to purchase and
maintain insurance on behalf of the Company, the Managers, the Members,
officers, employees or agents of the Company and any other Indemnitees at the
expense of the Company, against any liability asserted against or incurred by
them in any such capacity whether or not the Company would have the power to
indemnify such Persons against such liability under the provisions of this
Operating Agreement.

         7.2  Limitation of Liability. The debts, obligations and liabilities of
the Company shall be solely the debts, obligations and liabilities of the
Company; and, except as provided under the Act, no Manager or Member shall be
obligated personally for any such debt, obligation or liability of the Company
solely by reason of being a Manager or Member of the Company.

         7.3  Savings Clause. If this Article 7 or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, the Company
shall nevertheless indemnify and hold harmless each Indemnitee or any other
person indemnified pursuant to this Article 7 as to costs, charges and expenses
(including, without limitation, reasonable attorneys' fees), judgments, fines
and amounts paid in settlement with respect to any action, suit or proceeding,
whether civil, criminal, administrative or investigative, to the full extent
permitted by any applicable portion of this Article 7 that shall not have been
invalidated and to the fullest extent permitted by applicable law.

                                    ARTICLE 8
                           DISSOLUTION AND WINDING UP

         8.1  Dissolution. The Company shall be dissolved, its assets shall be
disposed of, and its affairs wound up on the first to occur of the following:

Percentage Interests to dissolve the Company; or

              (b) The entry of a decree of judicial dissolution under Section
18-802 of the Act.

              Except for the foregoing, the Company shall not dissolve on the
occurrence of any other event.

         8.2  Winding Up. Upon the occurrence of any event specified in Section
8.1, the Management Committee promptly shall notify each of the Members, and the
Company shall continue solely for the purpose of, and immediately begin the
process of, winding up its affairs in an orderly manner, liquidating its assets,
and satisfying the claims of its creditors. The Management Committee shall
promptly appoint a Person to act as the liquidator of the Company (the
"Liquidator") who shall be responsible for overseeing the winding up and
liquidation of the Company pursuant to the terms of this Operating Agreement.
The Liquidator shall give written notice of the commencement of winding up by
mail to all known creditors and claimants whose addresses appear on the records
of the Company.

         8.3  Reversion of Rights. Upon the occurrence of any event specified in
Section 8.1, or upon the valid termination of the Commercialization Agreement by
the Company, all of the rights granted by each of Patriot and TPL to the Company
pursuant to the P-Newco License and T-Newco License, respectively, shall
immediately and without further action by any of the parties thereto revert in
their entirety to each of Patriot and TPL, respectively.

         8.4  Order of Payment Upon Liquidation. Immediately after the reversion
of rights contemplated by Section 8.3 above, payment shall be made in the manner
contemplated by Section 6.1.

         8.5  Antecedent Activities.

              (a) The occurrence of any Recovery Event within twelve (12) months
of a Termination Event, as defined in Section 6.2 of the Commercialization
Agreement, shall entitle each of the Members to payment of the proceeds of such
Recovery Event in accordance with Section 6.1.

              (b) The entitlements set forth in Section 8.5(a) shall vest in
the Members without further action. All proceeds and incidents of any such
Recovery Event shall be transferred by the Member receiving such proceeds within
three Business Days (as defined in the Master Agreement) after receipt of such
proceeds directly into an independent escrow account approved by Patriot and TPL
for distribution pursuant to the terms of this Operating Agreement and the joint
instructions of Patriot and TPL.

         8.6 Limitations on Payments Made in Dissolution. Each Member shall only
be entitled to look to the assets of the Company for the return of its Initial
Capital Contribution, Working Capital Contribution and positive Capital Account
balance and shall have no recourse for its Initial Capital Contribution, Working
Capital Contribution, positive Capital Account balance and/or share of Gross
Cash Proceeds (upon dissolution or otherwise) against the Management Committee
or any other Member in the event the assets of the Company remaining after
payment of or due provision for all debts, liabilities and obligations of the
Company are insufficient to return such Member's Initial Capital Contribution
and positive Capital Account balance.

         8.7  Certificate of Cancellation. When all debts, liabilities and
obligations have been paid and discharged or adequate provisions have been made
therefor and all of the remaining property and assets have been distributed to
the Members, a certificate of cancellation shall be executed in duplicate and
verified by all three (3) Managers, which certificate shall set forth the
information required by the Act. Duplicate originals of the certificate of
cancellation shall be delivered to the Secretary of State of the State of
Delaware.

                                       23
<PAGE>

         8.8  Effect of Filing Certificate of Cancellation. Upon the issuance of
the certificate of cancellation, the existence of the Company shall cease. The
Management Committee shall have the authority to distribute any Company property
discovered after dissolution and take such other action as may be necessary on
behalf of and in the name of the Company.

                                    ARTICLE 9
                                  MISCELLANEOUS

         9.1  Amendment. The Management Committee shall have the duty and
authority to amend the Certificate of Formation as and to the extent necessary
to reflect any and all changes or corrections necessary or appropriate as a
result of any action taken by the Members in accordance with the terms of this
Operating Agreement. Members holding at least 75% of the Percentage Interests
shall have the authority to amend this Operating Agreement. Notwithstanding
anything to the contrary set forth herein, neither the Management Committee nor
the Members may amend the Certificate of Formation or this Operating Agreement
to decrease the Percentage Interest of a Member, increase the Working Capital
Contributions of a Member or the liability of a Member with respect to the
Company without the consent of each Member affected thereby.

         9.2  Governing Law and Severability. This Operating Agreement shall, in
all respects, be construed in accordance with and governed by the laws of the
State of Delaware as applied to agreements among Delaware residents entered into
and to be performed entirely within Delaware. If any provision of this Operating
Agreement becomes or is deemed invalid, illegal or unenforceable in any
jurisdiction by reason of the scope, extent or duration of its coverage, then
such provision shall be deemed amended to the extent necessary to conform to
applicable law so as to be valid and enforceable or, if such provision cannot be
so amended without materially altering the intention of the parties, then such
provision shall be stricken and the remainder of this Operating Agreement shall
continue in full force and effect. Should there ever occur any conflict between
any provision contained in this Operating Agreement and any present or future
statute, law, ordinance or regulation contrary to which the parties have no
legal right to contract, the latter shall prevail, but the provision of this
Operating Agreement affected thereby shall be curtailed and limited only to the
extent necessary to bring it into compliance with the law. All the other terms
and provisions of this Operating Agreement shall continue in full force and
effect without impairment or limitation.

         9.3  Counterparts. This Operating Agreement may be executed
simultaneously in multiple counterparts and by facsimile, each of which shall be
deemed an original, but all of which taken together shall constitute one and the
same instrument.

         9.4  Titles and Subtitles. The headings of this Operating Agreement are
inserted for convenience only and shall not constitute a part of this Operating
Agreement in construing or interpreting any provision hereof.

         9.5  Notices. All notices and other communications required or
permitted under this Operating Agreement shall be delivered to the parties at
the address appearing on the books of Company, or at such other address that
they designate by notice to all other parties in accordance with this section.
All notices and communications shall be deemed to have been received unless
otherwise set forth herein: (a) in the case of personal delivery, on the date of
such delivery; (b) in the case of facsimile transmission, on the date on which
the sender receives confirmation by facsimile transmission that such notice was
received by the addressee, provided that a copy of such transmission is
additionally sent by mail as set forth in (d) below; (c) in the case of
overnight air courier, on the second business day following the day sent, with
receipt confirmed by the courier; and (d) in the case of mailing by first class
certified or registered mail, postage prepaid, return receipt requested, on the
fifth business day following such mailing.

         9.6  Entire Agreement. This Operating Agreement, as well as the
Stipulated Final Judgment, Master Agreement, Commercialization Agreement and
Newco Licenses, constitutes the entire agreement and understanding of the
parties with respect to the terms and conditions of the transactions referred to
herein and therein and supersede all prior and contemporaneous agreements and
understandings, oral or written, between the parties relating to such subject
matter, other than as provided herein and therein.

         9.7  Power of Attorney. By signing this Operating Agreement, each
Member designates and appoints the Management Committee as their true and lawful
attorney, in his name, place and stead, to make, execute, sign and file such
instruments, documents or certificates which may from time to time be required
by the laws of the United States of America and the State of Delaware and any
political subdivision thereof or any other state or political subdivision in
which the Company shall do business to carry out the purposes of this Operating
Agreement, except where such action requires the express approval of a Member
hereunder. The Management Committee shall provide to the Members copies of all
documents executed pursuant to the power of attorney contained in this Section
9.7.

         9.8  Related Party Transactions. The Company shall not, without the
approval of the Management Committee, engage in any loans, leases, contracts or
other transactions with any Manager, officer or key employee of the Company, any
member of any such person's immediate family, including the parents, spouse,
children and other relatives of any such person, or any Person controlled by
such person, with the exception of the payments to be made to TPL pursuant to
Article IV of the Commercialization Agreement.

         9.9 Dispute Resolution. All rights and obligations under this Operating
Agreement shall be resolved as if all persons and all transactions related to
this Operating Agreement had their legal residence, situs, and employment in
Santa Clara County, California. Within 15 days after written notice of the
dispute, members of the most senior management of the parties shall meet and
exercise their best efforts to resolve any dispute under this Operating
Agreement. If the dispute is not resolved to the mutual satisfaction of the
parties within 30 days after such notice, the Company, Patriot and TPL shall
submit such dispute to expedited binding arbitration before a single arbitrator.
The arbitration shall be administered by the AAA. Judgment on the award,
including without limitation injunctive relief, may be entered in any court
having jurisdiction. All costs related to such arbitration shall be paid in
advance by the Company, including the cost of translating into English all
discoverable materials, and of providing contemporaneous translation of all live
testimony. All performances due hereunder by the Company, Patriot and TPL shall
continue unabated throughout the entire process and a final adjudication in
accordance with the terms hereof has been made from which no appeal or review
can be undertaken.

         9.10 No Partition. No Member nor any legal successor of a Member shall
have the right to partition the property of the Company or any part thereof or
interest therein, or to file a complaint or institute any proceeding at law or
in equity to partition the property of the Company or any part thereof or
interest therein. Each Member, for such Member and such Member's legal
successor, hereby waives any such rights. The Members intend that, during the
term of this Operating Agreement, the rights of the Members and their successors
in interest, as among themselves, shall be governed solely by the terms of this
Operating Agreement and by the Act.

         9.11 Bankruptcy. Neither the Management Committee, nor any Manager or
Member of the Company, shall be permitted to file a bankruptcy petition on
behalf of the Company unless the filing of the bankruptcy petition shall first
have been approved in writing by Members holding at least 75% of the Percentage
Interests of the Company.

9. Redemption.  Notwithstanding  anything to the contrary  herein,  in the event
that any one or more of the following occur (each, a "Redemption Trigger"),  the
Rights  Holder,  at its  option,  may  require  the  COMPANY to effect a Warrant
Redemption (as defined below) of any or all (at the Rights  Holders'  option) of
the Rights Holders' Warrants (as defined below):

         A.  The COMPANY  merges into or is bought  out by another  company,  or
         becomes a private  company that does  not have publicly  traded  common
         stock,  or sells all or  substantially all of the COMPANY's assets,  or
         B.  Common  stock of the COMPANY  is tendered,  purchased or  exchanged
         pursuant to a tender offer, purchase offer or exchange offer, or
         C.  There is a  Change of Control (as  defined below) of the  COMPANY's
         board of directors, and one or more of the following occurs:
                  (1) COMPANY sells, conveys,  disposes of, spins off or assigns
                  any or all of its NEWCO Stock,  or any or all of its rights to
                  receive the NEWCO  Income,  to any third  party,  in each case
                  without the Right Holder's written consent.
                  (2) The  COMPANY  issues or sells,  or agrees to issue or sell
                  Variable  Equity  Securities (as defined  below),  for cash in
                  private capital raising  transactions or any securities of the
                  Company pursuant to an equity line structure or format without
                  obtaining  the prior  written  approval of the Rights  Holder,
                  with the  exception of any such  agreements,  transactions  or
                  equity  lines  existing as of the date  hereof.  For  purposes
                  hereof, the following shall be collectively referred to herein
                  as,  the  "Variable  Equity  Securities":  any debt or  equity
                  securities (or securities pursuant to an equity line structure
                  or similar structure) which are convertible into,  exercisable
                  or exchangeable for, or carry the right to receive  additional
                  shares of Common Stock either (i) at any conversion,  exercise
                  or  exchange  rate or other  price that is based  upon  and/or
                  varies with the  trading  prices of or  quotations  for Common
                  Stock at any time after the  initial  issuance of such debt or
                  equity security, or (ii) with a fixed conversion,  exercise or
                  exchange  price  that  greater  than a  thirty  percent  (30%)
                  discount to the then prevailing  market or is subject to being
                  reset  at some  future  date at any  time  after  the  initial
                  issuance  of such debt or equity  security  due to a change in
                  the market price of the  Company's  Common Stock since date of
                  initial issuance.

         If a Redemption  Trigger has occurred  and the Rights  Holder  elects a
redemption,  then any of the Rights  Holders'  Warrants  selected  by the Rights
Holder for such  redemption  shall be  redeemed  ("Warrant  Redemption")  by the
Company as of the record date for such  Redemption  Trigger at a price per share
(that is, per share of common stock represented by the warrants) for each Rights
Holder  Warrant equal to the  "Redemption  Price," which shall be defined as the
greater of (A) $0.50 per share,  less the Exercise Price per share in effect for
that Rights Holder Warrant on the trading day  immediately  preceding the record
date of the  Redemption  Trigger  (each subject to adjustment to account for any
forward or reverse  stock  splits),  or (B) the  applicable  Warrant  Redemption
Market Value (as defined below).  For purposes hereof,  the "Warrant  Redemption
Market Value" shall equal the aggregate of the highest Warrant Market Values (as
defined  below)  for  all of the  Right  Holders'  Warrants  being  so  redeemed
calculated  on any date during the thirty (30) business day period ending on the
record date for the Redemption Trigger.

         For purposes hereof,

         "Change  in  Control"  shall  mean  any  change  in the  makeup  of the
COMPANY's  board of directors  such that the  remaining  board  members from the
following group do not constitute a majority of the board: Gloria Felcyn,  David

stock that have been issued from the Company to the Rights Holder for any reason
at any time in the past up through the date hereof.

          "Warrant  Market Value" shall equal the number of shares that would be
issuable in a "cashless  exercise" on the date in  question,  under the terms of
the  warrant   (without  regard  to  any   contractual,   legal,  or  regulatory
restrictions  on such  exercise  and  issuance,  if any,  and without  regard to
whether or not a  sufficient  number of shares are  authorized  and  reserved to
effect any such exercise and  issuance),  multiplied by the Closing Price of the
Company's common stock for the preceding trading day.

          "Closing  Price" shall mean the closing  price on the O.T.C.  Bulletin
Board, Nasdaq Small Cap Market, the National Market System ("NMS"), the New York
Stock  Exchange,  or if no longer  traded on the Nasdaq  Small Cap  Market,  the
National  Market  System  ("NMS"),  the New York Stock  Exchange,  or the O.T.C.
Bulletin  Board,  the "Closing  Bid Price" shall equal the closing  price on the
principal national securities exchange or the  over-the-counter  system on which
the Common  Stock is so traded and, if not  available,  the mean of the high and
low prices on the  principal  national  securities  exchange or other  market on
which the Common Stock is so traded.
