               (i)  If the Company's Royalty Receivable from such Covered

     Inventor and the Company; provided, that the Company and Inventor shall

     mutually agree to share any other applicable form of revenue, compensation
     or consideration earned or received by the Company from such third party
     (including, but not limited to upfront fees and warrants).

     2.2  Term of Payments.  Subject to Section 3.5, commencing on the date of
          ----------------
this Agreement, the Company shall make the Contract Payment specified in Section
3.1 for each Fiscal Quarter for a period of twenty-five years (the "Term"),
provided that the Company's obligation to make such Contract Payments shall
terminate in the event the Inventor (i) after 30 days notice from the Company of

Company or engages in a thermoelectric business competitive with the Company or
(iii) contests the validity or enforceability of the assignment of the
Technology under the Assignment Agreement except in connection with the
Inventor's reversionary rights under the Assignment Agreement upon the
liquidation or winding up of the Company.

     2.3  Timing of Payments.  The Contract Payment payable to the Inventor (or
          ------------------
the persons designated by the Inventor under Section 4.1), his successors, heirs
and permitted assigns shall be paid in arrears by the Company within 45 days

of the Company in the good faith exercise of its business judgment, irrespective
of the accounting treatment thereof) on the closing date of the Special Event
of:

                                       3
<PAGE>

          (a)  at least $25,000,000, but less than $50,000,000, then (i) from
such date forward, the aggregate amount of Contract Payments in any Fiscal Year
shall not exceed $5,000,000 and (ii) the Term of this Agreement shall be revised

date through the end of the Term of this Agreement specified in Section 2.2;

          (b)  at least $50,000,000, but less than $100,000,000, then from such

--------
but unpaid to the Inventor as of such date.

          -----------------------
approve, prior to execution, the Royalty Receivables in any license, agreement,
contract or similar arrangement entered into with a third party by the Company
in which Royalty Receivables will be less than 5% of the third party's Covered
Revenue from Covered Products.  The Company shall provide to the Inventor for
his approval the proposed terms of such Royalty Receivables (including, if
applicable, the types of equity interests described in Section 2.4 which may be
received) no later than 10 business days prior to the proposed execution of such
license, agreement, contract or similar arrangement for the Inventor's approval
shall not be unreasonable withheld.

                                  ARTICLE III

          PAYMENT DISCLAIMER AND REALLOCATION; PERMITTED ASSIGNMENTS

     3.1  Payment Disclaimer and Reallocation.  The Inventor shall have the
          -----------------------------------
right, no later than 15 days prior to the beginning of each Fiscal Quarter, to
deliver a written notice to the Company disclaiming the Inventor's right to
receive all or any part of the Contract Payment to be paid at the end of such
Fiscal Quarter (other than the share of the Contract Payment to be paid to
Inventor's permitted assigns).  Upon approval of the Board of Directors of the
Company of such a disclaimer, which approval shall not be unreasonably withheld,
the Inventor shall have the right to reallocate the amount of Contract Payment
disclaimed by the Inventor to current or former officers, employees, consultants
and contractors of the Company.  If the Inventor fails to instruct the Company,
then the Contract Payment payable at the end of such Fiscal Quarter shall be
paid to the Inventor.

     3.2  Payment Assignments.  The Inventor shall have the right to sell,
          -------------------
transfer or hypothecate ("assign") all or any part of the Inventor's right to
receive the Contract Payment.  Any such assignment shall be irrevocable and
subject to all pertinent laws and governmental regulations and to the rights of
the Company under this Agreement.  In the event of any such irrevocable
assignment by the Inventor, the Inventor shall deliver a written notice to the
Company detailing the name and address of the assignee and the amount of the
Contract

                                       4
<PAGE>

Payment that should be paid to the assignee. Following any such assignment, the
Inventor shall have no further right or interest in the assigned portion of the
Contract Payment and the assignee shall become a Holder of a Contract Payment
Interest and treated as "Inventor" for all purposes hereunder with respect to
his or her applicable percentage of the Contract Payment (other than with
respect to Section 2.6). If the Inventor assigns all of his right to receive the
Contract Payment, the Inventor shall cease to be a Holder of a Contract Payment
Interest. For purposes of this Section 3.2, the Company may rely on any written
notice believed by it to be genuine and to have been signed or presented by the
Inventor. The Company need not investigate any fact or matter stated in the
written notice.

                                  ARTICLE IV

                  AUDIT RIGHTS; OWNERSHIP; SALE OF TECHNOLOGY

     4.1  Accounting Records re Exploitation; Audit Rights.
          ------------------------------------------------

          (a)  The Company shall keep books of account relating to its
operations, together with records supporting the same (all of which are
hereinafter referred to as "records"). The Inventor may audit the applicable
records at the place where the Company maintains the same in order to verify
Statements rendered hereunder. Any such audit shall be conducted by a reputable
public accountant during reasonable business hours in such manner as not to
interfere with the Company's normal business activities. In no event shall an
audit with respect to any Statement commence later than 24 months from end of
the Fiscal Quarter to which such Statement relates; nor shall audits be made
hereunder more frequently than once annually; nor shall the records supporting
any Statement be audited more than once. All Statements rendered hereunder shall
be binding upon the Inventor and not subject to objection for any reason if the
Inventor has not commenced an audit thereof within 24 months from the end of the
Fiscal Quarter to which a Statement relates. If the Company, as a courtesy to
the Inventor, shall include cumulative figures in any Statement, the time within
which the Inventor may commence any audit or make any objection in respect of
any statement shall not be enlarged or extended thereby. Subject to Section
4.1(c), the fees and expenses incurred by the public accountant retained by the
Inventor in connection with any audit under this Section 4.1(a) shall be divided
evenly between the Company and the Inventor, provided that the Company shall not
be obligated to pay more than $25,000 of such fees and expenses per audit.

          (b)  If the Inventor contests any computations made in connection with
a Statement, the Inventor shall provide written notice to the Company stating
each item as to which the Investor takes exception, specifying reasonable detail
the nature and extent of any such exception.  If a proposed change is disputed
by the Company, then the Company and the Inventor shall negotiate in good faith
to resolve such dispute.  If, after a period of 20 days following the date on
which the Inventor gives the Company notice of any proposed change which remains
disputed, then the Company and the Inventor shall choose any independent firm of
public accountants of nationally recognized standing other than the auditor of
Amerigon Incorporated or the Company at such time to resolve any remaining
dispute.  The accounting firm shall act as an arbitrator to determine, based
solely on presentations by the parties and not by independent review, only those
issues still in dispute.  The decision of the accounting firm shall be final and
binding.  All of the fees and expenses of the accounting firm shall be paid

                                       5
<PAGE>

equally by the Company and the Investor; provided, however, that if the
                                         --------  -------
accounting firm determines that either party's position is totally correct, then
the other party shall pay 100% of the costs and expenses incurred by the
accounting firm in connection with any such determination.  Any disputes other
than computational errors shall be settled in accordance with Sections 5.6 and
5.7.

          (c)  If any audit of the Company's records by the Inventor reveals
that the Company has failed to properly account for and pay the Inventor the
Contract Payment that should have been paid for any Fiscal Quarter, and the
amount of any Contract Payment which the Company has failed to properly account
and pay for in aggregate in any Fiscal Year exceeds by 5% or more, the amount of
Contract Payment actually accounted for and paid to the Inventor for such Fiscal
Year, the Company shall, in addition to paying the Inventor such overdue
percentage of Contract Payment, pay the Inventor an additional 10% of the
Contract Payment that should have been paid for that Fiscal Year and reimburse
the Inventor for his direct, reasonable out-of-pocket expenses incurred in
conducting such audit.

          (d)  Any license, agreement, contract or similar arrangement entered
into Company with a third party in which Royalty Receivables are receivable by
the Company shall contain usual and customary rights to audit such third party.
The Inventor shall have access to all records received by the Company from such
third parties supporting Royalties Receivable and Covered Revenues received from
such third party for which a Contract Payment is payable to the Inventor.  The
Inventor shall further have the right to request the Company to exercise the
Company's audit rights with respect to third parties under any license,
agreement, contract or similar arrangement entered for which Royalty Receivables
are receivable and the Company shall reasonably comply with such request.

     4.2  Ownership.  The Inventor expressly acknowledges that the Inventor has
          ---------
and will have no right, title or ownership interest of any kind or character
whatsoever in or to the Basic Technology, or to the literary, scientific or
engineering material upon which the Basic Technology is based, or from which it
may be adapted, and no lien thereon or other rights thereto, except as expressly
provided herein and any reversionary rights upon a liquidation or winding up of
the Company; and that the same shall be and remain the Company's sole and
exclusive property.  Subject to the Inventor's rights hereunder, including,
without limitation, the Inventor's rights under Section 2.6, the Company shall
have the sole and exclusive right to utilize, sell, license or otherwise dispose
of all or any part of its rights in the Basic Technology or such literary,
scientific or engineering material.  The Company shall not be obligated to
segregate Contract Payment from its other funds, it being the intent and purpose
hereof that Contract Payment is referred to herein merely as a measure in
determining the time and manner of payment to Inventor.  The Contract Payment is
unfunded by the Company and subject to the claims of the Company's creditors.

     4.3  Exploitation.  As between the Inventor and the Company, subject to
          ------------
Section 2.6, the Company shall have complete authority to exploit the Basic
Technology and license the incorporation and use thereof throughout the world.
The Company shall have the broadest possible latitude in the exploitation of the
Basic Technology, and the exercise of its judgment in good faith in all matters
pertaining thereto shall be final.  The Company has not made any express or
implied representation, warranty, guarantee or agreement as to the amount of
proceeds

                                       6
<PAGE>

which will be derived from the exploitation of the Basic Technology, nor has the
Company made any express or implied representation, warranty, guarantee or
agreement that there will be any sums payable to Inventor hereunder, or that the
Basic Technology will be favorably received by manufacturers or consumers, or
will be exploited continuously. In no event shall the Company incur any
liability based upon any claim that the Company has failed to realize receipts
or revenue which should or could have been realized. Subject to Section 2.6, the
Company may exploit the Basic Technology itself or through such licensees,
sublicensees and other parties as the Company may, in its uncontrolled
discretion, determine, upon such terms and conditions as the Company may deem
advisable, and the Company may refrain from exploiting the Basic Technology in
any territory for any reason whatsoever.

     4.4  Sale of Technology.  The Company shall have the right at any time to
          ------------------
sell, transfer or assign all or any of its rights in and to the Basic
Technology.  Any such sale, transfer or assignment shall be subject to the
Inventor's rights hereunder, and upon the purchaser, transferee or assignee
assuming performance of this Agreement in place and stead of the Company, the
Company shall be released and discharged of and from any further liability or
obligation hereunder.  No part of any sales price or other consideration
received by, or payable to, the Company shall be included in the Company's
Covered Revenues and the Inventor shall have no rights under this Agreement in
respect of any thereof.

                                   ARTICLE V

under this Agreement, including the right to vote in proportion to the
Percentage Interest that the Assigning Member would have had in the event that

          ----------------------------
Substituted Member shall be subject to all the provisions of this Agreement that

upon reaching such Milestone, the Class A Member shall receive additional Class
A Common Units based on the issuance and sale of any New Securities issued and
sold by the Company since the Effective Date, such that the Class A Member will
have the number of Class A Common Units to which it otherwise would be entitled
under the first proviso of this Section 4.1 but for the condition precedent of
achieving the Milestone.

share of New Securities which the Company may, from time to time, propose to
sell and issue.  The Class A Member's pro rata share shall be equal to a number
such that the Percentage Interest owned by the Class A Member after the issuance
of New Securities is the same Percentage Interest as prior to the issuance of
New Securities.

     (a)  In the event the Company proposes to undertake an issuance of New
Securities subject to this Section 4.2, it shall promptly give the Class A
Member written notice of its intention, describing the type of New Securities,
their price and the general terms upon which the Company proposes to issue the

Securities for the price and upon the terms specified in the notice by giving
written notice to the Company and stating therein the quantity of New Securities
to be purchased.

     (b)  If the Class A Member fails to exercise its preemptive right within
said 20-day period, the Company shall have 120 days thereafter to sell or enter
into an agreement (pursuant to which the sale of New Securities covered thereby
shall be closed, if at all, within 60 days from the date of said agreement) to
sell the New Securities respecting which the Class A Member's preemptive right
was not exercised, at a price and upon terms no more favorable to the purchasers
thereof than specified in the Company's notice to the Class A Member pursuant to
Section 4.2(a).  In the event the Company has not sold the New Securities or
entered into an agreement to sell the New Securities in accordance with the
foregoing 120 day period (and closed the sale of such New Securities within 60
days from the date of said agreement), the

                                      14
<PAGE>

Company shall not after such date issue or sell any New Securities, without
first offering such securities to the Class A Member in the manner provided in
Section 4.2(a) above.

          SECTION 4.3    Equity "Step-Up" Rights.
                         -----------------------

     (a)  If the Class A Member does not completely vest the Initial Class A
Member Options before the closing date of a Special Event that results in the
Class A Member's Equity Ownership having an aggregate fair market value as
determined in good faith by the Board of Directors on the closing date of such
Special Event of at least $25,000,000 and, immediately prior to such date, the
Class A Member's Equity Ownership comprises a Fully-Diluted Percentage Interest
of less than 10%, then the Class A Member shall receive additional equity or
cash proceeds in connection with the consummation of such Special Event equal in
value to one-half of the difference between (i) the value of a Fully-Diluted
Percentage Interest of 10% (as valued in the Special Event) and (ii) the value
of the Class A Member's Equity Ownership immediately prior to such date (as
valued in the Special Event); provided, there shall be deducted from proviso (i)
above a value equal to the value of any Class A Common Units previously
transferred to any Person not part of the Family Group of the initial Class A
Member.

     (b)  If the Class A Member does completely vest the Initial Class A Member
Options before the closing date of a Special Event that results in the Class A
Member's Equity Ownership having an aggregate fair market value as determined in
good faith by the Board of Directors on the closing date of such Special Event
of at least $25,000,000 and, immediately prior to such date, the Class A
Member's Equity Ownership comprises a Fully-Diluted Percentage Interest of less
than 15%, then the Class A Member shall receive additional equity or cash
proceeds in connection with the consummation of such Special Event equal in
value to one-half of the difference between (i) the value of a Fully-Diluted
Percentage Interest of 15% (as valued in the Special Event) and (ii) the value
of the Class A Member's Equity Ownership immediately prior to such date (as
valued in the Special Event); provided, there shall be deducted from proviso (i)
above a value equal to the value of any Class A Common Units previously
transferred to any Person not part of the Family Group of the initial Class A
Member.

             ARTICLE V  --  RIGHTS, PREFERENCES AND PRIVILEGES OF
                            -------------------------------------
                         THE SERIES A PREFERRED UNITS
                         ----------------------------

          SECTION 5.1    Distribution Provisions.  In the event the Company
                         -----------------------
shall declare a Distribution payable in cash, securities of other persons,
evidences of indebtedness issued by the Company or other persons, assets
(excluding cash dividends) or options or rights not referred to in subsection
5.3(d), then, in each such case for the purpose of this subsection 5.3(e), the
Series A Members shall be entitled to a proportionate share of any such
Distribution as though they were the holders of the number of Common Units into
which their Series A Preferred Units are convertible as of the record date fixed
for the determination of the holders of Common Units entitled to receive such
Distribution.

                                      15

          SECTION 5.2    Liquidation Preference.
                         ----------------------

     (a)  In the event of any Liquidation or Dissolution of the Company, either
voluntary or involuntary, the Series A Members shall be entitled to receive,
prior and in preference to any distribution of any of the assets of the Company
to the Class A Members and the Class B Members, but subject to the prior rights
of the initial Class A Member pursuant to Section 14.2(e), an amount per Series
A Preferred Unit equal to the sum of (i) $1,000 for each Series A Preferred Unit
(the "Original Issue Price"), (ii) an amount equal to 7% of the Original Issue
Price annually, and (iii) an amount equal to any declared but unpaid
distributions on such Series A Preferred Unit (the amounts in (ii) and (iii)
being referred to herein as the "Premium").  If upon the occurrence of such
event, the assets and funds thus distributed among the Series A Members shall be
insufficient to permit the payment to such Members of the full aforesaid
preferential amounts, then the entire assets and funds of the Company legally
available for distribution shall be distributed ratably among the Series A
Members in proportion to the amount of such Series A Preferred Units owned by
each such Member.

     (b)  Upon the completion of the distribution required by Section 5.2(a), if
assets remain in the Company, the Class A Members and Class B Members shall
receive all of the remaining assets.

          SECTION 5.3    Conversion.  The Series A Member shall have conversion
                         ----------
rights as follows (the "Conversion Rights"):

     (a)  Right to Convert.  Each Series A Preferred Unit shall be convertible,
          ----------------
at the option of the holder thereof, at any time after the date of issuance of
such Unit, at the office of the Company or any transfer agent for such Units,
into such number of fully paid and nonassessable Class B Common Units as is
determined by dividing the Original Issue Price by the conversion price
("Conversion Price") applicable to such Unit, determined as hereafter provided,
in effect on the date the certificate is surrendered for conversion.  The
initial Conversion Price per Series A Preferred Unit shall be $2.2222; provided,
however, that the Conversion Price for the Series A Preferred Units shall be
subject to adjustment as set forth in subsection 5.3(d).

     (b)  Automatic Conversion. Each Series A Preferred Unit shall automatically
          --------------------
be converted into Class B Common Units at the Conversion Price at the time in
effect for such Series A Preferred Unit immediately upon the date specified by
written consent or agreement of the holders of a Majority in Interest of the
Series A Preferred Units.

     (c)  Mechanics of Conversion.  Before any Series A Member shall be entitled
          -----------------------
to convert the same into Class B Common Units, it shall surrender the
certificate or certificates therefor, duly endorsed, at the office of the
Company or of any transfer agent for the Series A Preferred Units, and shall
give written notice to the Company at its principal office, of the election to
convert the same and shall state therein the name or names in which the
certificate or certificates for Class B Common Units are to be issued.  The
Company shall, as soon as practicable thereafter, issue and deliver at such
office to such Series A Member, or to the nominee or nominees of such holder, a
certificate or certificates for the number of Class B Common Units to which such
holder shall be entitled as aforesaid.  Such conversion shall be

                                      16
<PAGE>

deemed to have been made immediately prior to the close of business on the date
of such surrender of the Series A Preferred Units to be converted, and the
person or persons entitled to receive the Class B Common Units issuable upon
such conversion shall be treated for all purposes as the record holder or
holders of such Class B Common Units as of such date. If the conversion is in
connection with an underwritten offering of securities registered pursuant to
the Securities Act of 1933, the conversion may, at the option of any holder
tendering Series A Preferred Units for conversion, be conditioned upon the
closing with the underwriters of the sale of securities pursuant to such
offering, in which event the person(s) entitled to receive the Class B Common
Units upon conversion of the Series A Preferred Units shall not be deemed to
have converted such Series A Preferred Units until immediately prior to the
closing of such sale of securities.

     (d)  Conversion Price Adjustments of Series A Preferred Units for Certain
          --------------------------------------------------------------------
Dilutive Issuances, Splits and Combinations.  The Conversion Price of the Series
-------------------------------------------
A Preferred Units shall be subject to adjustment from time to time as follows:

          (i)   In the event the Company should at any time or from time to time
after the date upon which any Series A Preferred Units were first issued (the
"Purchase Date" with respect to such series) fix a record date for the
effectuation of a split or subdivision of the outstanding Common Units or the
determination of holders of Common Units entitled to receive a Distribution
payable in additional Common Units without payment of any consideration by such
holder for the additional Common Units (other than pursuant to Section 4.1),
then, as of such record date (or the date of such Distribution, split or
subdivision if no record date is fixed), the Conversion Price of the Series A
Preferred Units shall be appropriately decreased so that the number of Class B
Common Units issuable on conversion of each Series A Preferred Unit shall be
increased in proportion to such increase of the aggregate of Common Units. In
the event the Company shall declare or pay, without consideration, any
Distribution on the Common Units payable in any right to acquire Common Units
for no consideration, then the Company shall be deemed to have made a
Distribution payable in Common Units in an amount of Units equal to the maximum
number of Units issuable upon exercise of such rights to acquire Common Units.

          (ii)  If the number of Common Units at any time after the Purchase
Date is decreased by a combination of the outstanding Common Units, then,
following the record date of such combination, the Conversion Price for the
Series A Preferred Units shall be appropriately increased so that the number of
Common Units issuable on conversion of each unit of such series shall be
decreased in proportion to such decrease in Common Units.

          (iii) All adjustments to the Conversion Price will be calculated to
the nearest cent of a dollar. No adjustment in the Conversion Price will be
required unless such adjustment would require an increase or decrease of at
least one cent per dollar; provided, however, that any adjustments which by
reason of this Section 5.3(d)(iii) are not required to be made shall be carried
forward and taken into account in any subsequent adjustment. All adjustments to
the Conversion Price shall be made successively.

     (e)  Recapitalizations and Reorganizations.  If the Class B Common Units
          -------------------------------------
issuable upon conversion of the Series A Preferred Units shall be changed into
or exchanged for a

                                      17
<PAGE>

different class or classes of units, or other securities or property whether by
reorganization, recapitalization or otherwise (other than a subdivision,
combination or merger or sale of assets transaction provided for elsewhere in
this Section 5.3 or Section 5.2) provision shall be made so that the Series A
Member shall thereafter be entitled to receive upon conversion of the Series A
Preferred Units the number of units or other securities or property, to which a
holder of Class B Common Units deliverable upon conversion would have been
entitled on such recapitalization or reorganization. In any such case,
appropriate adjustment shall be made in the application of the provisions of
this Section 5.3 with respect to the rights of the Series A Member after the
recapitalization or reorganization to the end that the provisions of this
Section 5.3 (including adjustment of the Conversion Price then in effect and the
number of shares purchasable upon conversion of the Series A Preferred Units)
shall be applicable after that event as nearly equivalent as may be practicable.

     (f)  No Impairment.  This Company will not, by amendment of this Agreement
          -------------
or through any reorganization, recapitalization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Company, but will at all
times in good faith assist in the carrying out of all the provisions of this
Section 5.3 and in the taking of all such action as may be necessary or
appropriate in order to protect the Conversion Rights of the Series A Member
against impairment.

     (g)  No Fractional Units and Certificate as to Adjustments.
          -----------------------------------------------------

          (i)  No fractional units shall be issued upon the conversion of any
Series A Preferred Units, and the number of Class B Common Units to be issued
shall be rounded to the nearest whole unit.  Such conversion shall be determined
on the basis of the total number of Series A Preferred Units the holder is at
the time converting into Class B Common Units and the number of Class B Common
Units issuable upon such aggregate conversion.

          (ii) Upon the occurrence of each adjustment or readjustment of the
Conversion Price of the Series A Preferred Units pursuant to this Section 5.3,
the Company, at its expense, shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
Series A Member a certificate setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based.
The Company shall, upon the written request at any time of any Series A Member,
furnish or cause to be furnished to such holder a like certificate setting forth
(A) any such adjustment and readjustment, (B) the Conversion Price for such
series of Preferred Units at the time in effect, and (C) the number of Class B
Common Units and the amount, if any, of other property which at the time would
be received upon the conversion of a Series A Preferred Unit.

     (h)  Reservation of Units Issuable Upon Conversion.  The Company shall at
          ---------------------------------------------
all times reserve and keep available out of its authorized but unissued Class B
Common Units, solely for the purpose of effecting the conversion of the Series A
Preferred Units, such number of its Class B Common Units as shall from time to
time be sufficient to effect the conversion of all Series A Preferred Units; and
if at any time the number of authorized but unissued Class B Common Units shall
not be sufficient to effect the conversion of all then outstanding Series A
Preferred Units, in

                                      18
<PAGE>

addition to such other remedies as shall be available to the holder of such
Series A Preferred Units, the Company will take such action as may, in the
opinion of its counsel, be necessary to increase its authorized but unissued
Class B Common Units to such number of Units as shall be sufficient for such
purposes.

          SECTION 5.4    Voting Rights.  The Series A Member shall have the
                         -------------
right to one vote for each Class B Common Unit into which such Series A
Preferred Unit could then be converted, and with respect to such vote, such
holder shall have full voting rights and powers equal to the voting rights and
powers of the holders of Class B Common Units, and shall be entitled,
notwithstanding any provision hereof, to notice of any meeting of the Members in
accordance with this Agreement and shall be entitled to vote, together with
holders of the Common Units as a single class, with respect to any question upon
which holders of the Common Units have the right to vote.

                          ARTICLE VI  --   MANAGEMENT
                                           ----------

          SECTION 6.1    Manager; Management and Control; Day to Day Affairs of
                         ------------------------------------------------------
the Company.  The day-to-day business and affairs of the Company shall be
-----------
operated and managed by the Officers, provided that the affairs of the Company
shall be overseen by the Board of Directors.  Any Officer acting pursuant to
authority granted by the Board or the provisions of this Agreement is authorized
to take any actions, to make any determinations and to provide any consents
permitted to be taken, made or provided by the Company under this Agreement;
provided, however, that no Officer shall take any action, make any determination
or provide any consent expressly reserved by this Agreement to the Members or to
the Board of Directors or reserved to the Board of Directors pursuant to an
action duly and validly taken by the Board of Directors.  No Member or Director
or Officer shall, acting individually, have the power to sign or bind the
Company unless duly authorized to do so by the Board of Directors or this
Agreement.  Notwithstanding the foregoing, no Officer shall have liability to
the Members or the Company for exceeding the authority granted to such Officer
in the event a decision made or an action taken by such Officer was made or
taken with a reasonable good faith belief that such decision or action was
within the scope of the day-to-day business and affairs of the Company.  The
Board shall from time to time set the compensation for each of the Officers of
the Company, and shall not be permitted to delegate such authority to any
Officer or Officers (in their capacity as such).

          SECTION 6.2    Board of Directors.
                         ------------------

     (a)  Designated Board.  As of the date hereof, the members of the Board
          ----------------
shall be John W. Clark, Oscar B. Marx III, Richard A. Weisbart, and Dr. Lon E.
Bell, and the Members desire to appoint a prominent figure in thermoelectrics
recommended by the Class A Member to the Board.  The Members shall promptly
cause such a figure to be appointed to the Board.  Following this initial Board
composition, at each meeting of the Members for the election of directors or any
solicitation of written consents for such purpose, the Class A Member and the
Series A Member hereby agree to vote all Voting Interests entitled to vote in
the election of directors now owned or hereafter acquired or controlled by them
(collectively, the "Members' Voting Interests"), and otherwise use their best
efforts as Members to elect the Designated

                                      19
<PAGE>

Board (as defined below), which shall constitute the entire Board. The
"Designated Board" shall consist of (i) one member designated by the Class A
Member, (ii) three members designated by the Series A Member, and (iii) one
prominent figure in thermoelectrics recommended by the Class A Member and
approved by a majority of the Directors not designated by the Class A Member.
The Members hereby agree that, if the size of the Board of Directors is
increased or decreased, the "Designated Board" shall consist of (i) one member
designated by the Class A Member, (ii) one prominent figure in thermoelectrics,
and (iii) all remaining members designated by the Series A Member; provided,
however, that if the Class A Member's Percentage Interest is ever less than 5%,
the Designated Board shall consist of members designated entirely by the Series
A Member.

     (b)  Failure to Vote per Agreement.  In the event that any Series A Member
          -----------------------------
or Class A Member shall fail to vote its Voting Interests so as to achieve the
structure of the Board and/or representation thereon for the designees set forth
in Section 6.2(a), such Member shall be deemed immediately upon the existence of
such a breach to have granted to the person or persons entitled to designate or
recommend the director(s) for which such Member failed to vote, a proxy to vote
its Voting Interests to ensure that such Voting Interests will be voted for such
nominee.  Each of the Series A Member and the Class A Member acknowledges that
each proxy granted hereby, including any successive proxy if need be, is given
to secure the performance of a duty and shall be irrevocable until the duty is
performed.

     (c)  Certain Resignations or Removals.
          --------------------------------

          (i)   Each of Class A Member and the Series A Member shall also have
the right at any time to request, in a signed writing submitted to the Secretary
of the Company, the resignation or removal of a Director originally designated
or recommended by such Member. In such event, the affected Director shall
immediately resign or be subject to removal by a vote of the Members, and the
Members shall vote all of their Voting Interests in favor of such removal.

          (ii)  If any Director is no longer entitled to be designated to be a
Director pursuant to Section 6.2(a), such Director shall immediately resign or
be subject to removal by a vote of the Members, and the Members shall vote all
of their Voting Interests in favor of such removal.

          (iii) If the affected director shall fail to resign upon the
occurrence of the events specified in Section 6.2(c)(i) or 6.2(c)(ii), then any
Member shall have the right to call a special meeting of the Members or solicit
written consents of the Members for the purpose of removing such director and
the Members shall vote all of their Voting Interests in favor of removal.

     (d)  Filling Vacancies.  In the event of the death, removal or resignation
          -----------------
of any Director, any Member shall have the right to call a special meeting of
Members for the purpose of electing a Director (provided that such Director
shall be designated in accordance with Section 6.2(a)) to fill the vacancy
created by such death, removal or resignation.  Any party entitled to designate
a Director to fill such vacancy that fails to do so prior to the election of a
replacement by the Members hereunder may call a special meeting of Members or
solicit written consents of

                                      20
<PAGE>

Members for the purpose of removing the Director so elected and electing such
party's designee to the Board, or such party may designate a Director for
election at the next annual meeting of Members to succeed the Director elected
by the Members pursuant to this Section 6.2(d). In any such event, the Members
shall vote all of their Voting Interests in favor of the designee of the party
originally entitled to designate a Director to fill such vacancy.

     (e)  Notices.
          -------

          (i)  The Company shall promptly give each of the Members written
notice of any request by a Member for the resignation or removal of a member of
the Board.

          (ii) Notice shall be given to each member of the Board at least 14
days prior to any meeting of the Board at which it is proposed that a vacancy on
the Board be filled unless such notice shall have been waived by such member of
the Board.

     (f)  Covenant to Vote.  Each of the Members shall appear in person or by
          ----------------
proxy at any annual or special meeting of Members for the purpose of obtaining a
quorum and shall vote the Voting Interest held by such Member entitled to vote,
either in person or by proxy, at any annual or special meeting of Members called
for the purpose of voting on the election of Directors or by consensual action
of Members with respect to the election of Directors, in favor of the election
of the Directors designated in accordance with Sections 6.2(a) and 6.2(d).  In
addition, each Member shall appear in person or by proxy at any annual or
special meeting of Members for the purpose of obtaining a quorum and shall vote
their Voting Interests entitled to vote upon any other matter submitted to a
vote of the Members of the Company in a manner so as to be consistent and not in
conflict with, and to implement, the terms of this Agreement.

     (g)  No Voting or Conflicting Agreements.  No Member shall grant any proxy
          -----------------------------------
or enter into or agree to be bound by any voting trust with respect to the
Voting Stock held by such Member nor shall any Member enter into any Member
agreements or arrangements of any kind with any person with respect to the
Voting Interests inconsistent with the provisions of this Agreement (whether or
not such agreements and arrangements are with other Members of the Company that
are not parties to this Agreement).  No Member shall act, for any reason, as a
member of a group or in concert with any other persons in connection with the
acquisition, disposition or voting of the Company's Units in any manner that is
inconsistent with the provisions of this Agreement.

     (h)  Injunctive Relief.  It is acknowledged that it will be impossible to
          -----------------
measure in money the damages that would be suffered if the parties fail to
comply with any of the obligations imposed on them pursuant to this Article VI
and that in the event of any such failure, an aggrieved person will be
irreparably damaged and will not have an adequate remedy at law.  Any such
person shall, therefore, be entitled to injunctive relief, including specific
performance, to enforce such obligations, and if any action shall be brought in
equity to enforce any of the provisions of this Agreement, none of the parties
hereto shall raise the defense that there is an adequate remedy at law.

                                      21
<PAGE>

     (i)  Terms.  Each Director shall serve until the earlier of (i) such
          -----
Director's resignation, removal, retirement, death, or disability and (ii) the
expiration of such Director's term as a Director.

     (j)  Compensation of Directors.  Each Director shall be entitled to
          -------------------------
compensation for the Director's services as determined by the Board from time to
time and to reimbursement for all expenses reasonably incurred by the Director
in the performance of the Director's duties.

     (k)  Indemnification.  The Company shall indemnify the Directors to the
          ---------------
fullest extent permitted by law and as set forth in Article XII.

     (l)  Voting.  Each Director shall have one vote in any decision of the
          ------
Board.  The Directors may participate in a meeting of the Board by means of
conference telephone or similar communications equipment by means of which all
persons participating in the meeting can hear or otherwise interactively
communicate with each other, and such participation shall constitute presence in
person at such meeting.  Any action which may be taken at a meeting of the Board
may be taken without a meeting if Directors casting votes sufficient to approve
such action consent thereto in writing and the Company provides notice of such
action to all other Directors.

     (m)  Meetings. A meeting of the Board shall be held at such times as called
          --------
by a Majority in Interest of the Members, the Class A Member, or the Series A
Member.  No other regular meetings of the Board of Directors are required to be
held.  The meetings shall be noticed, held and conducted pursuant to this
Agreement.  In any instance in which the approval of the Board is required under
this Agreement, such approval may be obtained in any manner as permitted by the
DLLCA, including without limitation by the unanimous written consent of the
members of the Board.

     (n)  Powers and Duties of Directors. Subject to the provisions of the DLLCA
          ------------------------------
and any limitations in this Agreement relating to actions that are required to
be approved by the Board, the business and affairs of the Company shall be
managed and all Company powers shall be exercised by or under the direction of
the Board.  Without prejudice to these general powers, and subject to the same
limitations, the Board shall have the power to:

          (i)   Select and remove all Officers, agents, and employees of the
Company; prescribe any powers and duties for them that are consistent with law,
with the Certificate, and with this Agreement; fix their compensation;

          (ii)  Change the principal executive office or the principal business
from one location to another; cause the Company to be qualified to do business
in any other state; territory, dependency, or country and conduct business
within or outside the State of California and designate any place within or
outside the State of California for holding any Members' meeting or meetings,
including annual meetings.

          (iii) Prescribe the forms of certificates of Membership Interests; and
alter the form of the seal and certificates;

                                      22
<PAGE>

          (iv)   Authorize the issuance of Membership Interests of the Company
on any lawful terms, in consideration of money paid, labor done, services
actually rendered, debts or securities cancelled, or tangible or intangible
property actually received;

          (v)    Borrow money and incur indebtedness on behalf of the Company,
and cause to be executed and delivered for the Company's purposes, in the name
of the Company, promissory notes, bonds, debentures, deeds of trust, mortgages,
pledges, hypothecations, and other evidences of debt and securities;

          (vi)   Determine or adopt the annual budget of the Company (or
material modifications thereof);

          (vii)  Adopt or approve business plans of the Company (or material
modifications thereof);

          (viii) Cause or permit the merger or consolidation of the Company into
or with another Person other than pursuant to Section 6.4 in connection with a
Qualified IPO, or cause or permit the conversion of the Company into another
form of business entity other than in connection with a Qualified IPO; or

          (ix)   Cause or permit the registered offering of any of the Company's

all examinations of the Company's affairs by any tax authorities, including
resulting judicial and administrative proceedings. Each Member agrees, and each
holder of a Membership Interest who is not a Member (including any Person who
holds an Economic Interest in the Company) shall be deemed by virtue of its
ownership of a Membership Interest to agree, that it shall furnish the Tax
Matters Member with such information as the Tax Matters Member may reasonably
request in order to allow the Tax Matters Member to provide the Internal Revenue
Service or other taxing jurisdiction with sufficient information with respect to
any such proceedings. The decisions of the Tax Matters Member shall be final and
binding as to all Members except to the extent that any Member files a statement
not to be bound by a settlement pursuant to Code Section 6224(c)(3). The Tax
Matters Member shall furnish to the Members a copy of all notices or other
written communications received by the Tax Matters Member from the Internal
Revenue Service or any state or local taxing authority (except such notices or
communications as are sent directly to the Members) and shall keep all Members
fully informed of the progress of any audits, examinations, or other tax
proceedings.

          SECTION 9.6    No Partnership.  The classification of the Company as a
                         --------------
partnership shall apply only for federal (and, as appropriate, state and local)
income tax purposes, and the Company shall not make an election to be treated as
other than a partnership for income tax purposes under (S)301.7701-3(c) of the
Treasury Regulations.  This characterization, solely for tax purposes, does not
create or imply a general partnership among the Members for state law or any
other purpose.  The Members acknowledge the status of the Company as a limited
liability company formed under the DLLCA.

                ARTICLE X  --  CAPITAL ACCOUNTS AND ALLOCATIONS
                               --------------------------------

          SECTION 10.1   Maintenance.  Each Member agrees that a single capital
                         -----------
account (each a "Capital Account") shall be established and maintained for each
Member and shall be credited, charged, and otherwise adjusted as provided in
this Article X and as required by the regulations promulgated under (S)704(b) of
the Code (the "(S)704(b) Regulations").  The Capital Account of each Member
shall be:

                                      32
<PAGE>

     (a)  credited with (i) each Capital Contribution made by such Member, (ii)
such Member's allocable share of Net Profits and other items of income and gain
of the Company, including items of income and gain exempt from tax, and (iii)
all other items properly credited to the Capital Account of such Member as
required by the (S)704(b) Regulations; and

     (b)  charged with (i) each Distribution made to such Member by the Company,
(ii) such Member's allocable share of Net Losses and other items of loss and
deduction of the Company, including items of loss and deduction non-deductible
for tax purposes, and (iii) all other items properly charged to the Capital
Account of such Member as required by the (S)704(b) Regulations.

          The provisions of this Section 10.1 relating to maintenance of Capital
Accounts have been included in this Agreement to comply with Section 704(b) of
the Code and the 704(b) Regulations and shall be interpreted and applied in a
manner consistent with those provisions.

          SECTION 10.2   Allocation of Net Profits and Net Losses.  Except as
                         ----------------------------------------
otherwise provided in this Agreement, items of income, gain, loss and deductions
of the Company shall be allocated among the Members in pro rata in accordance
with their respective Percentage Interests (and as if the Series A Preferred
Units were fully converted).

          SECTION 10.3   Special Allocations.
                         -------------------

     (a)  Subject to the exceptions stated in Treasury Regulation Sections
1.704-2(f) and 1.704-2(i)(4), if there is a net decrease in Company Minimum Gain
or Member Nonrecourse Debt Minimum Gain during a Fiscal Year, each Member will
be specially allocated items of income and gain for Capital Account purposes for
such year (and, if necessary, for subsequent years) in an amount equal to such
Member's share of such net decrease during such year (which share of such net
decrease will be determined under Treasury Regulations Sections 1.704-2(g)(2)
and 1.704-2(i)(5)). The Members intend that this Section 10.3(a) comply with the
minimum gain chargeback requirements in such Treasury Regulations Sections and
will be interpreted consistently therewith.

     (b)  Any Nonrecourse Deductions will be allocated to the Members in
proportion to their Percentage Interest (and as if the Series A Preferred Units
were fully converted).

     (c)  Any Member Nonrecourse Deductions will be allocated to the Members as
provided in Treasury Regulation Section 1.704-2(i)(1).

     (d)  If any Member unexpectedly receives any adjustments, allocations or
distributions described in Treasury Regulations Sections 1.704-
1(b)(2)(ii)(d)(4),(5) or (6) (modified as appropriate, by Treasury Regulations
Section 1.704-2(g)(1) and 1.704-2(i)(5)), items of Company income and gain for
Capital Account purposes for such Fiscal Year will be specially allocated to the
Member in an amount and manner sufficient to eliminate, to the extent required
by the Treasury Regulations, any deficit balance in the Adjusted Capital Account
of the Member as quickly as possible, provided, that an allocation pursuant to
this Section 10.3(d) will be made if and only to the extent that the Member
would have an Adjusted Capital Account deficit after

                                      33
<PAGE>

all other allocations provided for in this Agreement have been tentatively made
as if this Section 10.3(d) were not in the Agreement.

     (e)  Notwithstanding the foregoing provisions of Section 10.2 and Section
10.3, a Member will not be allocated any item of loss or deduction if such
allocation would cause or increase a deficit balance in such Member's Adjusted
Capital Account.  Instead, such item of loss or deduction will be allocated to
the Members entitled to receive such allocation under Treasury Regulation
Section 1.704 in proportion to their respective Percentage Interest.

     (f)  To the extent any adjustment to the adjusted tax basis of any Company
asset pursuant to Code Section 734(b) or Code Section 743(b) is required,
pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into
account in determining Capital Accounts, appropriate adjustments to the Capital
Accounts shall be made.

     (g)  The allocations stated in Sections 10.3(a) through (f) above (the
"Regulatory Allocations"), are intended to comply with certain requirements of
the Treasury Regulations.  Notwithstanding the provisions of Section 10.3, the
Regulatory Allocations can be taken into account in allocating other items of
income, gain, loss and deduction among the Members so that, to the extent
possible, the net amount of such allocations of other items and the Regulatory
Allocations to each Member will be equal to the net amount that would have been
allocated to each such Member if the Regulatory Allocations had not occurred.

          SECTION 10.4   Tax Allocations.
                         ---------------

     (a)  All items of income, gain, loss or deduction for federal, state and
local income tax purposes will be allocated in the same manner as the
corresponding "book" items are allocated under Sections 10.2, 10.3 or 10.4;
provided, however, in the case of any Company asset the Gross Asset Value of
which differs from its adjusted tax basis for federal income tax purposes,
income, gain, loss and deduction with respect to such asset will, solely for tax
purposes, be allocated among the Members so as to take account of any variation
between the adjusted basis of such asset for federal income tax purposes and its
Gross Asset Value in accordance with the principles of Sections 704(b) and
704(c) of the Code (in any permissible manner determined by the Board).

     (b)  Any elections or other decisions relating to the foregoing tax
allocations will be made by the Board in any manner that reasonably reflects the
purpose and intention of this Agreement.  Allocations pursuant to this Section
10.4 are solely for tax purposes and will not affect the computation of any
Member's Capital Account, except as otherwise required under the Code.

          SECTION 10.5   Allocation Between Assignor and Assignee.  The portion
                         ----------------------------------------
of the income, gain, losses and deductions of the Company for any Fiscal Year
during which an Interest is assigned by a Member (or by an assignee or successor
in interest to a Member), that is allocable with respect to such Interest will
be apportioned between the assignor and the assignee of the Interest on whatever
reasonable, consistently applied basis selected by the Board and permitted by
the applicable Treasury Regulations under Section 706 of the Code.

                                      34
<PAGE>

          SECTION 10.6   Tax Reporting.  The Members are aware of the income tax
                         -------------
consequences of the allocations made by this Article X and hereby agree to be
bound by the provisions of this Article X in reporting their Company income and
loss for income tax purposes.

          SECTION 10.7   Profit Shares.  Solely for purposes of determining a
                         -------------
Member's proportionate share of the Company's "excess nonrecourse liabilities,"
as defined in Treasury Regulation Section 1.752-3(a), the Members' interests in
Company profits will be deemed to be in proportion to their relative Capital
Contributions.

                         ARTICLE XI  --  DISTRIBUTIONS
                                         -------------

          SECTION 11.1   Distributions.  Distributions, other than during a
                         -------------
Liquidation, shall, from time to time until Dissolution be made in such amounts
and at such times, if any, as the Board shall determine.  Distributions shall be
made to the Members pro rata in accordance with their respective Percentage
Interests (and including the Series A Member pursuant to Section 5.1).

          SECTION 11.2   Withholding.
                         -----------

     (a)  If required by the Code or by state, local, or foreign law, the
Company shall withhold any required amount from Distributions to a Member for
payment to the appropriate taxing authority. Any amount so withheld from a
Member shall be treated as a Distribution by the Company to such Member. Each
Member agrees to timely file any document that is required by any taxing
authority in order to avoid or reduce any withholding obligation that would
otherwise be imposed on the Company.

     (b)  To the extent any amount that is required to be withheld with respect
to a Member and paid over to an appropriate taxing authority exceeds the amounts
distributed or deemed distributed to such Member in respect of such withholding,
such excess amounts paid to the taxing authority in respect of such withholding
shall be treated as a loan to such Member that is payable on demand.

                       ARTICLE XII  --  INDEMNIFICATION
                                        ---------------

          SECTION 12.1   Indemnification by Company.  Any Person who was or is a
                         --------------------------
Member, Director, Officer, employee, or other agent of the Company, or was or is
serving at the request of the Company as a director, officer, employee, or other
agent of another limited liability company, corporation, partnership, joint
venture, trust, or other enterprise (collectively, the "Indemnified Party")
shall, in accordance with this Article XII, be indemnified and held harmless by
the Company from and against any and all losses, claims, damages, liabilities,
expenses (including reasonable legal and other professional fees and
disbursements), judgments, fines, settlements, and other amounts incurred
(collectively, the "Indemnification Obligations") in connection with any and all
claims, demands, actions, suits, or proceedings (civil, criminal,
administrative, or investigative), actual or threatened, in which such
Indemnified Party may be involved, as a party or otherwise, by reason of such
Indemnified Party's service to, or on behalf of, or management of the affairs
of, the Company, or rendering of advice or consultation with

                                      35
<PAGE>

respect thereto, whether or not the Indemnified Party continues to be serving in
the above-described capacity at the time any such Indemnification Obligation is
paid or incurred. Notwithstanding the foregoing, no indemnification shall be
provided by the Company with respect to any Indemnification Obligation that
resulted from action or inaction of such Indemnified Party that, in each case,
constituted gross negligence, willful misconduct, a breach of the Indemnified
Party's fiduciary duty or duty of loyalty to the Company, or an act (a) that was
not in good faith, (b) that involved a knowing violation of law, or (c) from
which the Indemnified Party derived an improper personal benefit. The Company
shall also indemnify and hold harmless any Indemnified Party from and against
any Indemnification Obligation suffered or sustained by such Indemnified Party
by reason of any action or inaction of any employee, broker, or other agent of
such Indemnified Party, whether or not the Indemnified Party continues to be
serving in the above-described capacity at the time any such Indemnification
Obligation is paid or incurred, provided, that such employee, broker, or agent
                                --------
was selected, engaged, or retained by such Indemnified Party with reasonable
care. The termination of a proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere, or its equivalent, shall not, of
itself, create a presumption that such Indemnification Obligation resulted from
the gross negligence or willful misconduct of such Indemnified Party. Expenses
(including reasonable legal and other professional fees and disbursements)
incurred in any proceeding shall be paid by the Company, as incurred, in advance
of the final disposition of such proceeding upon receipt of an undertaking by or
on behalf of such Indemnified Party to repay such amount if it shall ultimately
be determined that such Indemnified Party is not entitled to be indemnified by
the Company as authorized hereunder.

          SECTION 12.2   Indemnification Not Exclusive.  The indemnification
                         -----------------------------
provided by Section 12.1 shall not be deemed to be exclusive of any other rights
to which each Indemnified Party may be entitled under any agreement, or as a
matter of law, or otherwise, both as to action in such Indemnified Party's
official capacity and to action in another capacity, and shall continue as to
such Indemnified Party who has ceased to have an official capacity for acts or
omissions during such official capacity or otherwise when acting at the request
of the Company, or any Person granted authority thereby, and shall inure to the
benefit of the heirs, successors, and administrators of such Indemnified Party.

          SECTION 12.3   Insurance on Behalf of Indemnified Party.  The Company
                         ----------------------------------------
shall have the power but not the obligation to purchase and maintain insurance
on behalf of each Indemnified Party, at the expense of the Company, against any
liability which may be asserted against or incurred by him in any such capacity,
whether or not the Company would have the power to indemnify the Indemnified
Parties against such liability under the provisions of this Agreement.

          SECTION 12.4   No Agency.  No Member acting solely in the capacity of
                         ---------
a Member is an agent of the Company, nor can any Member acting solely in the
capacity of a Member bind the Company or execute any instrument on behalf of the
Company.  Accordingly, each Member shall indemnify, defend, and hold harmless
each other Member and the Company from and against any and all loss, cost,
expense, liability, or damage arising from or out of any claim based upon any
action by such Member in contravention of the first sentence of this Section
12.4.  The foregoing indemnification by a Member shall not be deemed to be
exclusive

                                      36
<PAGE>

of any other rights to which the party indemnified thereby may be entitled under
any agreement, as a matter of law, or otherwise.

          SECTION 12.5   Indemnification Limited by Law.  Notwithstanding any of
                         ------------------------------
the foregoing to the contrary, the provisions of this Article XII shall not be
construed so as to provide for any indemnification for any liability to the
extent (but only to the extent) that such indemnification would be in violation
of applicable law or that such liability may not be waived, modified, or limited
under applicable law, but shall be construed as to effectuate the provisions of
this Article XII to the fullest extent permitted by law.

          SECTION 12.6   Amendment of Agreement.  The indemnification provided
                         ----------------------
for in this Article XII shall apply as written here to acts occurring prior to
any amendment of this Agreement, notwithstanding such amendment to this
Agreement.

                         ARTICLE XIII  --   DISSOLUTION
                         -----------------  -----------

          SECTION 13.1   Dissolution.  Dissolution of the Company shall occur
                         -----------
upon the happening of any of the following events:

     (a)  the affirmative vote of a Majority in Interest of the Members;

     (b)  the entry of a decree of judicial dissolution under Section 18-802 of
the DLLCA; or

     (c)  pursuant to Section 3.5(a)(iii).

          SECTION 13.2   Withdrawal of a Member.  No Member shall have the right
                         ----------------------
or power to withdraw from the Company.

                         ARTICLE XIV  --  LIQUIDATION
                                          -----------

          SECTION 14.1   Liquidation.  Upon Dissolution of the Company, the
                         -----------
Company shall immediately proceed to wind up its affairs and liquidate.  A
reasonable time shall be allowed for the orderly Liquidation of the Company and
the discharge of liabilities to creditors so as to enable the Company to
minimize any losses attendant upon Liquidation.  Any gain or loss on disposition
of any Company assets in Liquidation shall be allocated among the Members and
credited or charged to Capital Accounts in accordance with the provisions of
this Agreement.  Until the filing of the certificate of dissolution under
Section 14.4 and without affecting the liability of Members or imposing
liability on the liquidating trustee, the Board may settle and close the
Company's business, prosecute and defend suits, dispose of its property,
discharge or make provision for its liabilities, and make Distributions in
accordance with the priorities set forth in Section 14.2.

          SECTION 14.2   Priority of Payment.  The assets of the Company shall
                         -------------------
be distributed in Liquidation in the following order:

                                      37
<PAGE>

     (a)  To creditors, including Members who are creditors, by the payment or
provision for payment of the debts and liabilities of the Company and the
expenses of Liquidation;

     (b)  To the setting up of any reserves that the Board determines is
reasonably necessary for any contingent or unforeseen liabilities or obligations
of the Company;

     (c)  After determining that all known debts and liabilities of the Company
in the process of winding-up, including, without limitation, debts and
liabilities to Members who are creditors of the Company, have been paid or
adequately provided for, the remaining assets shall be distributed in accordance
with the priorities set forth in Section 5.2;

     (d)  Liquidating distributions shall be made by the end of the Company's
taxable year in which the Company is liquidated, or, if later, within 90 days
after the date of such liquidation.  It is intended that the distributions set
forth in this Section 14.2(c) comply with the intention of Treasury Regulations
Section 1.704-1(b)(2)(ii)(b)(2) that liquidating distributions to Members be
made in accordance with positive Capital Accounts.  However, if the balances in
the Capital Accounts do not result in such requirement being satisfied, no
change in the amounts of distributions pursuant to said Sections shall be made;
rather, items of income, gains, loss, deduction, and credit shall be reallocated
among the Members so as to cause the balances in the Capital Accounts to be in
the amounts necessary so that, to the extent possible, such result is achieved;
and

     (e)  Notwithstanding anything in this Section 14.2 to the contrary, the
Basic Technology (as defined in the Revenue Sharing Agreement dated as of
September 4, 2000 between the Company and the Class A Member) is subject to a
reversionary interest upon Liquidation or Dissolution of the Company and such
Basic Technology shall be assigned, transferred and conveyed to the initial
Class A Member upon such events prior to any other distributions made pursuant
to Section 14.2(b) or (c) and shall not be deemed to be an asset of the Company
for purposes of this Section 14.2.

          SECTION 14.3   Liquidating Reports.  A report shall be submitted with
                         -------------------
each liquidating Distribution, showing the collections, disbursements and
Distributions during the period which is subsequent to any previous report.  A
final report, showing cumulative collections, disbursements, and Distributions,
shall be submitted upon completion of the liquidation process.

          SECTION 14.4   Certificate of Dissolution.  Within 90 days following
                         --------------------------
the Dissolution of the Company and the commencement of winding up of its
business, or at any other time there are no Members, the Company shall file a
certificate of dissolution (to cancel the Certification of Formation) with the
Secretary of State of the State of Delaware pursuant to the DLLCA.  At such
time, the Company shall also file an application for withdrawal of its
certificate of authority in any jurisdiction where it is then qualified to do
business.

          SECTION 14.5   Deficit Capital Account.  Upon a liquidation of the
                         -----------------------
Company within the meaning of (S)1.704-1(b)(2)(ii)(g) of the Treasury
Regulations, if any Member has a negative Capital Account (after giving effect
to all contributions, Distributions, allocations, and

                                      38
<PAGE>

other adjustments for all Fiscal Years, including the Fiscal Year in which such
liquidation occurs), the Member shall have no obligation to make any Capital
Contribution, except as otherwise expressly required by the DLLCA, and the
negative balance of any Capital Account shall not be considered a debt owed by
the Member to the Company or to any other person for any purpose.

          SECTION 14.6   Nonrecourse to Other Members.  If the assets of the
                         ----------------------------
Company remaining after the payment or discharge of the debts and liabilities of
the Company are insufficient to return any Capital Contribution of any Member,
such Member shall have no recourse against any other Member.

                    ARTICLE XV  --   TRANSFER RESTRICTIONS
                                     ---------------------

          SECTION 15.1   Member's Obligations.  If any Member (the "Transferring
                         --------------------
Member") proposes to make a Transfer of Units, such Transferring Member shall
comply with the terms and conditions of this Article XV at any time prior to a
Qualified IPO.

          SECTION 15.2   Sale Notice.  Prior to making a Transfer of Units, the
                         -----------
Transferring Member shall give at least 60 days' prior written notice (the "Sale
Notice") to the Company and any non-Transferring Member (the "Non-Transferring
Member") (a) identifying (i) the type and amount of Units to be sold (the
"Offered Units"), (ii) the price at which the Transferring Member proposes to
Transfer the Offered Units (the "Offer Price") and (iii) the proposed closing
date for the Transfer (which date shall be not less than 60 days and not more
than 90 days after the date of the Sale Notice), (b) describing any other terms
and conditions of such proposed Transfer, and (c) identifying each prospective
transferee.

          SECTION 15.3   Co-Sale/Tag-Along Rights.  Any Member may, within 20
                         ------------------------
days of the receipt of the Sale Notice, give written notice (each, a "Co-Sale
Notice") to the Transferring Member that such Non-Transferring Member wishes to
participate in such proposed Transfer upon the terms and conditions set forth in
the Sale Notice, which Co-Sale Notice shall specify the Offered Units such Non-
Transferring Member desires to include in such proposed Transfer.

     (a)  If the Transferring Member does not receive any timely Co-Sale Notices
with respect to the Transfer proposed in the Sale Notice, then the Transferring
Member may Transfer such Offered Units on the terms and conditions set forth in
the Sale Notice at any time within 30 days after expiration of the 20-day period
for giving Co-Sale Notices with respect to such Transfer.  Any Offered Units not
Transferred by the Transferring Member during such 30-day period will again be
subject to the provisions of this Section 15.3 upon subsequent Transfer.  Should
the Transferring Member receive one or more timely Co-Sale Notices, then the
Transferring Member shall use all reasonable efforts to cause the prospective
transferee(s) to agree to acquire all such additional Units on the same terms
and conditions as applicable to the Offered Units.  If the prospective
transferee(s) is unwilling or unable to acquire all such additional Units upon
such terms, then the Transferring Member may elect either to cancel such
proposed Transfer or to allocate the maximum number of Units that the
prospective transferee(s) is willing to purchase among the Transferring Member
and each Non-Transferring Member that

                                      39
<PAGE>

gave timely Co-Sale Notices in the proportion of the Fully-Diluted Percentage
Interests owned by each such Non-Transferring Member bears to the Fully-Diluted
Percentage Interests owned by all such Non-Transferring Members (not to exceed,
however, with respect to any such Non-Transferring Member, the amount of Offered
Units proposed to be transferred in such Non-Transferring Member's Co-Sale
Notice, as the case may be) and to consummate such Transfer on those terms.

     (b)  Notwithstanding the provisions of this Section 15.3, the Class A
Member shall be subject to Section 15.3 for the three year period after the
Effective Date. After the end of such three year period, one-third of any Units
held by the Class A Member at such time shall become cumulatively excluded from
the provisions of Section 15.3 per year over the next three years.

          SECTION 15.4   Right of First Refusal.  After receipt of the Sale
                         ----------------------
Notice, each of the Company and the Non-Transferring Member (each an "ROFR
Offeree") may give written notice (a "Notice of Exercise"), within the time
periods and in the priority specified below, to the Transferring Member that
such ROFR Offeree wishes to exercise the right to purchase at the Offer Price
all but not less than all of the Offered Units.  The right of the ROFR Offerees
pursuant to this Section 15.4 shall terminate if the ROFR Offerees have not
delivered one or more Notices of Exercise relating, in the aggregate, to all of
the Offered Units within 20 days after the Company's receipt of the Sale Notice.

     (a)  The Sale Notice shall constitute an offer to sell the Offered Units to
the ROFR Offerees in the following priority: (i) the Company shall be given the
first right to elect to acquire the Offered Units; and (ii) to the extent the
Company fails to elect to acquire all of the Offered Units, any Non-Transferring
Member may elect to acquire the Offered Units.

     (b)  Within 20 days after receipt of the Sale Notice, the Company may elect
to purchase, at the price and on the terms specified in the Sale Notice, all of
the Offered Units by delivering a written notice of exercise to the Members.

     (c)  If the Company elects not to purchase the Offered Units, the Company
shall provide written notice (the "Company Notice") to the Non-Transferring
Members within 20 days following the receipt of the Sale Notice that the Company
has not elected to purchase all or any of the Offered Units.  Within 20 days
following the receipt of the Company Notice, the Non-Transferring Members shall
have the right to purchase or obtain, at the price and on the terms specified in
the Sale Notice, such remaining Units (the "Remaining Interests").  The Non-
Transferring Members shall exercise its right to purchase or obtain the
Remaining Interests by giving written notice thereof to the Transferring Member
within five Business Days after receipt by the Non-Transferring Members of the
Company Notice.

     (d)  If the Offer Price, or a portion of the Offer Price, involves
consideration other than cash, the ROFR Offerees shall have the right to
purchase the Offered Units for a cash amount equal to the sum of the portion of
such consideration which is cash plus the Cash Value (as defined below) of the
non-cash consideration.  For purposes of this Section 15.4, "Cash Value" shall
mean, in the case of securities which are quoted on any national securities
exchange, cash in an amount equal to the average of the last reported sales
price on such

                                      40
<PAGE>

exchange for such securities for the five trading days prior to the date of the
Sale Notice and, in the case of securities or other property for which there is
no such readily available market price, an amount equal to the fair market value
of such securities or property as determined in good faith by the Board.

     (e)  If the ROFR Offerees exercise their rights to purchase a portion of
the Offered Units in accordance with Section 15.4, then the Transferring Member
must sell such portion of the Offered Units to such party or parties.

     (f)  At the closing of the purchase of the Offered Units, the Transferring
Member shall deliver to the applicable ROFR Offerees certificates evidencing the
Offered Units, duly endorsed, or accompanied by written instruments of transfer
in form reasonably satisfactory to the applicable ROFR Offerees, duly executed
by the Transferring Member, free and clear of any Encumbrances, against payment
of the purchase price therefor in cash.  The closing date shall be the date
specified by the Transferring Member in the Sale Notice or such other date as is
mutually agreed upon by the appropriate parties.

     (g)  The Transferring Member may, during the 180-day period following the
expiration of the period in which a notice of exercise may be given, sell or
enter into an agreement to sell the Offered Units to any person or persons at a
price not less than, and upon terms no more favorable to the offeree than, those
specified in the Sales Notice.  If the Transferring Member does not enter into
an agreement for the sale of the Offered Units within such period, or if such
agreement is not consummated within 90 days of the execution thereof, the right
provided in this Section 15.4 shall be deemed to be revived and such Offered
Units shall not be offered unless first reoffered to the Company and the Non-
Transferring Members in accordance with this Article XV.

          SECTION 15.5   Securities Act Compliance.  No Units may be Transferred
                         -------------------------
by a Member (other than pursuant to an effective registration statement under
the Securities Act) unless such Member first delivers to the Company an opinion
of counsel, which opinion and counsel shall be reasonably satisfactory to the
Company, to the effect that such Transfer is not required to be registered under
the Securities Act.

          SECTION 15.6   Permitted Transfers.  Notwithstanding Sections 15.3 and
                         -------------------
15.4, a Member may Transfer or cause to be transferred all or any portion of
such Member's Units:  (i) to any person with the consent of the Company
(including, but not limited to, a sale by public offering); (ii) to any person
in the Family Group of the Member; (iii) by will or by the laws of descent and
distribution; (iv) by pledge to secure a bona fide loan made by a lending
institution; and (v) as part of any combination, exchange, merger,
consolidation, redemption, retirement, recapitalization, or reorganization
generally affecting the Units (or any class or series of Units) (each of (i)
through (v), a "Permitted Transfer").

          SECTION 15.7   Transferees Bound by Agreement.  Subject to compliance
                         ------------------------------
with the other provisions of this Article XV, a Member may Transfer any Units
held by such Member in accordance with applicable law; provided, however, that
the transferee of such security shall be bound by all the terms and provisions
of this Agreement and no Transfer shall be valid or a

                                      41
<PAGE>

permitted transfer unless such transferee consents in writing to be bound by the
terms of this Agreement applicable to Members.

          SECTION 15.8   Transfers in Violation of Agreement.  Any Transfer or
                         -----------------------------------
attempted Transfer of any Units in violation of any provision of this Agreement
shall be void, and the Company shall not record such Transfer on its books nor
treat any purported transferee of such Units as the owner of such Units for any
purpose.

          SECTION 15.9   Series A Member's Drag Along Right.  In connection with
                         ----------------------------------
a sale to a third party by the Series A Member of all Units owned by the Series
A Member, at the Series A Member's election and in its sole discretion, the
Series A Member shall have the right to cause all other Members to sell their
Units in such sale to such third party upon the same terms and conditions as the
sale by the Series A Member to such third party; provided, that such other
Members receive all cash consideration and are not required to make
representations and warranties other than regarding their authority to transfer
their Units and the lack of Encumbrances with respect to the Units.

                     ARTICLE XVI  --   REGISTRATION RIGHTS
                                       -------------------

          SECTION 16.1   Request for Registration.
                         ------------------------

     (a)  If the Company shall receive at any time after six months after the
effective date of the first registration statement for a public offering of
securities of the Company (other than a registration statement relating either
to the sale of securities to employees of the Company pursuant to a stock
option, stock purchase or similar plan or a Rule 145 transaction), a written
request from Holders of Registrable Securities of 5% or more of the Registrable
Securities then outstanding (provided, that the Class A Member may submit a
written request for less than 5% of the Registrable Securities is such amount
constitutes all of Registrable Securities of the Class A Member) ("Initiating
Holders"), requesting that the Company file a registration statement under the
Securities Act covering the registration of a portion of the Registrable
Securities then outstanding, then, provided, that, the Registrable Securities
held by the Initiating Holders have an anticipated aggregate public offering
amount of not less than $7,500,000, the Company shall:

          (i)   within 15 days of the receipt thereof, give written notice of
such request to all Holders of Registrable Securities; and

          (ii)  effect as soon as practicable, and in any event within 90 days
of the receipt of such request, the registration under the Securities Act of all
Registrable Securities which the Holders of Registrable Securities request to be
registered, subject to the limitations of subsection 16.1.(b), within 15 days of
the mailing of such notice by the Company.

     (b)  If the Initiating Holders intend to distribute the Registrable
Securities covered by their request by means of an underwriting, they shall so
advise the Company as a part of their request made pursuant to Section 16.1(a)
and the Company shall include such information in the written notice referred to
in subsection 16.1(a).  The underwriter will be selected by the Company and
shall be reasonably acceptable to a majority in interest of the Initiating
Holders.

                                      42
<PAGE>

In such event, the right of any Holder of Registrable Securities to include
securities in such registration shall be conditioned upon the participation in
such underwriting by such Holder of Registrable Securities and the inclusion of
the securities of such Holder of Registrable Securities in the underwriting
(unless otherwise mutually agreed by a majority in interest of the Initiating
Holders and such Holder of Registrable Securities) to the extent provided
herein. All Holders of Registrable Securities proposing to distribute their
securities through such underwriting shall (together with the Company as
provided in subsection 16.2(b)) enter into an underwriting agreement in
customary form with the underwriter or underwriters selected for such
underwriting. Notwithstanding any other provision of this section 16.1(b), if
the underwriter advises the Initiating Holders in writing that marketing factors
require a limitation of the number of securities to be underwritten, then the
Company shall so advise all Holders of Registrable Securities and other holders
of securities subject to registration rights which would otherwise be
underwritten pursuant hereto, and the number of securities that may be included
in the underwriting on behalf of each Holder of Registrable Securities shall be
allocated on a pro-rata basis among the selling holders according to the total
number of securities held by each such selling holder and entitled to inclusion
therein on the basis of a registration rights agreement with the Company;
provided, however, that the number of Registrable Securities to be included in
such underwriting shall not be reduced unless all other securities are first
entirely excluded from the underwriting and registration. For purposes of
allocating securities to be included in any offering, for any selling holder
which is a partnership or Company, the "affiliates" (as defined in Rule 405
under the Securities Act), partners, retired partners and shareholders of such
holder (and in the case of a partnership, any affiliated partnerships), or the
estates and family members of any such partners and retired partners and any
trusts for the benefit of any of the foregoing persons shall be deemed to be a
single "selling holder," and any pro-rata reduction with respect to such
"selling holder" shall be based upon the aggregate amount of Units carrying
registration rights owned by all entities and individuals included in such
"selling holder," as defined in this sentence. To facilitate the allocation of
Units in accordance with the above provisions, the Company may round the number
of Units allocated to any Holder of Registrable Securities to the nearest 100
Units.

     (c)  Notwithstanding the foregoing, if the Company shall furnish to Holders
of Registrable Securities requesting a registration statement pursuant to this
Section 16.1, a certificate signed by the President stating that in the good
faith judgment of the Board of the Company, it would be seriously detrimental to
the Company and its shareholders for such registration statement to be filed and
it is therefore essential to defer the filing of such registration statement,
the Company shall have the right to defer taking action with respect to such
filing for a period of not more than 90 days after receipt of the request of the
Initiating Holders; provided, however, that the Company may not utilize this
right more than twice in any twelve-month period.

     (d)  In addition, the Company shall not be obligated to effect, or to take
any action to effect, any registration pursuant to this Section 16.1:

          (i)   after the Company has effected two registrations pursuant to
this Section 16.1 and such registrations have been declared or ordered
effective; provided that, a registration shall not count against this limitation
in the event the number of Registrable

                                      43
<PAGE>

Securities to be include in the registration has been reduced by more than one-
third of the original number of Registrable Securities for which registration
was sought;

          (ii)  during the period starting with the date 60 days prior to the
Company's good faith estimate of the date of filing of, and ending on a date 180
days after the effective date of, (x) a previous registration subject to this
Section 16.1, (y) the Company's initial registered offering of its securities to
the general public (other than a registration statement relating to either the
sale of securities to employees of the Company pursuant to an option or similar
plan or an Rule 145 transaction) or (z) a previous registration subject to
Section 16.2 of this Agreement; provided that, the Company is actively employing
in good faith all reasonable efforts to cause such registration statement to
become effective;

          (iii) In any particular jurisdiction in which the Company would be
required to execute a general consent to service of process, unless the Company
is already subject to service in such jurisdiction and except as required by the
Securities Act; or

          (iv)  If the Initiating Holders propose to dispose of Registrable
Securities that may be immediately registered on Form S-3 pursuant to a request
made pursuant to Section 16.3 below.

          SECTION 16.2   Company Registration.
                         --------------------

     (a)  If (but without any obligation to do so) the Company proposes to
register (including for this purpose a registration effected by the Company for
holders other than the Holders of Registrable Securities) any of its securities
under the Securities Act in connection with the public offering of such
securities solely for cash (other than a registration relating solely to the
sale of securities to participants in a Company option plan, a registration
pursuant to a Rule 145 transaction, a registration on any form which does not
include substantially the same information as would be required to be included
in a registration statement covering the sale of the Registrable Securities or a
registration in which the only Units being registered is Units issuable upon
conversion of debt securities which are also being registered), the Company
shall, at such time, promptly give each Holder written notice of such
registration. Upon the written request of each Holder given within fifteen (15)
days after mailing of such notice by the Company, the Company shall, subject to
the provisions of paragraph 16.2(b) below, cause to be registered under the
Securities Act all of the Registrable Securities that each such Holder has
requested to be registered.

     (b)  In connection with any offering involving an underwriting of
securities, the Company shall not be required under this Section 16.2 to include
any of the securities of such Holders of Registrable Securities in such
underwriting unless they accept the terms of the underwriting as agreed upon
between the Company and the underwriters selected by it (or by other persons
entitled to select the underwriters), and then only in such quantity as the
underwriters determine in their sole discretion will not jeopardize the success
of the offering by the Company.  If the total amount of securities, including
Registrable Securities, requested by holders to be included in such offering
exceeds the amount of securities sold other than by the Company that the
underwriters determine in their sole discretion is compatible with the success

                                      44
<PAGE>

of the offering, then the Company shall be required to include in the offering
only that number of such securities, including Registrable Securities, which the
underwriters determine in their sole discretion will not jeopardize the success
of the offering, but in no event shall (i) the amount of securities of the
selling Holders of Registrable Securities included in the offering be reduced
below twenty-five percent (25%) of the total amount of securities included in
such offering, unless such offering is the initial public offering of the
Company's securities, in which case the Holders of Registrable Securities may be
excluded entirely if the underwriters make the determination described above and
no other holder's securities are included or (ii) notwithstanding (i) above, any
Units being sold by a holder exercising a demand registration right pursuant to
Section 16.1 be excluded from such offering. Allocation of securities to be sold
in any such offering shall be made on a pro-rata basis among the selling holders
according to the total number of securities held by each such selling holder and
entitled to inclusion therein on the basis of a registration rights agreement
with the Company; provided, however, that the number of Units of Registrable
Securities to be included in such offering shall not be reduced unless all other
securities (other than shares to be issued by the Company) are first entirely
excluded from the offering. For purposes of allocation of securities to be
included in any offering, for any selling holder which is a partnership or
Company, the "affiliates" (as defined in Rule 405 under the Securities Act),
partners, retired partners and holders of such holder (and in the case of a
partnership, any affiliated partnerships), or the estates and family members of
any such partners and retired partners and any trusts for the benefit of any of
the foregoing persons shall be deemed to be a single "selling holder," and any
pro-rata reduction with respect to such "selling holder" shall be based upon the
aggregate amount of Units carrying registration rights owned by all entities and
individuals included in such "selling holder," as defined in this sentence.

          SECTION 16.3   Form S-3 Registration.  In case the Company shall
                         ---------------------
receive from any Holder or Holders of Registrable Securities a written request
or requests that the Company effect a registration on Form S-3 and any related
qualification or compliance with respect to all or a part of the Registrable
Securities owned by such Holder or Holders of Registrable Securities, the
Company will:

     (a)  promptly give written notice of the proposed registration, and any
related qualification or compliance, to all other Holders of Registrable
Securities;

     (b)  as soon as practicable, effect such registration and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of the Registrable
Securities as are specified in such request, together with all or such portion
of the Registrable Securities of any other Holder or Holders of Registrable
Securities joining in such request as are specified in a written request given
within 15 days after receipt of such written notice from the Company; provided,
however, that the Company shall not be obligated to effect any such
registration, qualification or compliance, pursuant to this Section 16.3:  (1)
if the Registrable Securities requested by all Holders of Registrable Securities
to be registered pursuant to this Section 16.3 have an anticipated aggregate
offering price to the public (before deducting any underwriter discounts,
concessions or commissions) of less than $750,000; (2) if Form S-3 is not
available for such offering by the Holders of Registrable Securities; (3) if the
Company shall furnish to the Holders of Registrable Securities a certificate
signed by the President of the Company stating that in the good faith judgment
of the Board of

                                      45
<PAGE>

the Company, it would be seriously detrimental to the Company and its holders
for such Form S-3 Registration to be effected at such time, in which event the
Company shall have the right to defer the filing of the Form S-3 registration
statement for a period of not more than 90 days after receipt of the request of
the Holder or Holders of Registrable Securities under this Section 16.3;
provided, however, that the Company shall not utilize this right more than twice
in any twelve month period; (4) if the Company has, within the 12 month period
preceding the date of such request, already effected two (2) or more
registrations on Form S-3 for the Holders of Registrable Securities pursuant to
this Section 16.3; or (5) in any particular jurisdiction in which the Company
would be required to qualify to do business or to execute a general consent to
service of process in effecting such registration, qualification or compliance;
and

     (c)  Subject to the foregoing, the Company shall file a registration
statement covering the Registrable Securities and other securities so requested
to be registered as soon as practicable after receipt of the request or requests
of the Holders of Registrable Securities.  Registrations effected pursuant to
this Section 16.3 shall not be counted as demands for registration or
registrations effected pursuant to Sections 16.1 or 16.2, respectively.

          SECTION 16.4   Obligations of the Company.  Whenever required under
                         --------------------------
this Article XVI to effect the registration of any Registrable Securities, the
Company shall, as expeditiously as reasonably possible:

     (a)  Prepare and file with the Commission a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of the Holders
of Registrable Securities holding a majority of the Registrable Securities
registered thereunder, keep such registration statement effective for a period
of up to 90 days or, if longer, until the distribution contemplated in the
Registration Statement has been completed; provided, however, that such 90-day
period shall be extended for a period of time equal to the period the Holder
refrains from selling any securities included in such registration at the
request of an underwriter of securities of the Company.

     (b)  Prepare and file with the Commission such amendments and supplements
to such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by such
registration statement.

     (c)  Furnish to the Holders of Registrable Securities such numbers of
copies of a prospectus, including a preliminary prospectus, in conformity with
the requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Registrable
Securities owned by them.

     (d)  Use its best efforts to register and qualify the securities covered by
such registration statement under such other securities or blue sky laws of such
jurisdictions as shall be reasonably requested by the Holders of Registrable
Securities; provided that the Company shall not be required in connection
therewith or as a condition thereto to qualify to do business or to file a
general consent to service of process in any such states or jurisdictions.

                                      46
<PAGE>

     (e)  In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering.  Each Holder participating
in such underwriting shall also enter into and perform its obligations under
such an agreement.

     (f)  Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

     (g)  Cause all such Registrable Securities registered pursuant hereunder to
be listed on each securities exchange on which similar securities issued by the
Company are then listed.

     (h)  Provide a transfer agent and registrar for all Registrable Securities
registered pursuant hereunder and a CUSIP number for all such Registrable
Securities, in each case not later than the effective date of such registration.

     (i)  In the event of any underwritten public offering, cooperate with the
selling Holders of Registrable Securities, the underwriters participating in the
offering and their counsel in any due diligence investigation reasonably
requested by the selling Holders of Registrable Securities or the underwriters
in connection therewith, and participate, to the extent reasonably requested by
the managing underwriter for the offering or the selling Holder, in efforts to
sell the Registrable Securities under the offering (including, without
limitation, participating in "roadshow" meetings with prospective investors)
that would be customary for underwritten primary offerings of a comparable
amount of equity securities by the Company.

          SECTION 16.5   Furnish Information.
                         -------------------

     (a)  It shall be a condition precedent to the obligations of the Company to
take any action pursuant to this Article XVI with respect to the Registrable
Securities of any selling Holder that such Holder shall furnish to the Company
such information regarding itself, the Registrable Securities held by it, and
the intended method of disposition of such Securities as shall be required to
effect the registration of such Holder's Registrable Securities.

     (b)  The Company shall have no obligation with respect to any registration
requested pursuant to Section 16.1 or Section 16.3 if, due to the operation of
subsection 16.5(a), the number of Units or the anticipated aggregate offering
price of the Registrable Securities to be included in the registration does not
equal or exceed the number of Units or the anticipated aggregate offering price
required to originally trigger the Company's obligation to initiate such
registration as specified in subsection 16.1(a) or subsection 16.3(b), whichever
is applicable.

          SECTION 16.6   Expenses of Demand, Company or S-3 Registration.  All
                         ------------------------------------------------

pursuant to this Article XVI including

                                      47
<PAGE>

(without limitation) all registration, filing and qualification fees, printers'
and accounting fees, fees and disbursements of counsel for the Company and the
reasonable fees and disbursements of one counsel for all selling Holders of
Registrable Securities shall be borne by the Company.

          SECTION 16.7   Delay of Registration.  No Holder shall have any right
                         ----------------------
to obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Article XVI.

          SECTION 16.8   Indemnification.  In the event any Registrable
                         ---------------
Securities are included in a registration statement under this Article XVI:

     (a)  To the extent permitted by law, the Company will indemnify and hold
harmless each Holder, the constituent partners and members, or officers and
directors of each Holder, any underwriter (as defined in the Securities Act) for
such Holder and each person, if any, who controls such Holder or underwriter
within the meaning of the Securities Act or the Exchange Act, against any
losses, claims, damages, or liabilities (joint or several) to which they may
become subject under the Securities Act, the Exchange Act or other federal or
state law, insofar as such losses, claims, damages, or liabilities (or actions
in respect thereof) arise out of or are based upon any of the following
statements, omissions or violations (collectively a "Violation"):  (i) any
untrue statement or alleged untrue statement of a material fact contained in
such registration statement, including any preliminary prospectus or final
prospectus contained therein or any amendments or supplements thereto, (ii) the
omission or alleged omission to state therein a material fact required to be
stated therein, or necessary to make the statements therein not misleading, or
(iii) any violation or alleged violation by the Company of the Securities Act,
the Exchange Act, any state securities law or any rule or regulation promulgated
under the Securities Act, the Exchange Act or any state securities law; and the
Company will pay to each such Holder, underwriter or controlling person any
legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability, or action,
as such expenses are incurred; provided, however, that the indemnity agreement
contained in this subsection 16.8(a) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable in any such case
for any such loss, claim, damage, liability, or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by any such Holder, underwriter or controlling person.

     (b)  To the extent permitted by law, each selling Holder will indemnify and
hold harmless the Company, each of its directors, each of its officers who has
signed the registration statement, each person, if any, who controls the Company
within the meaning of the Securities Act, any underwriter, any other Holder
selling securities in such registration statement and any controlling person of
any such underwriter or other Holder, severally but not jointly, against any
losses, claims, damages, or liabilities (joint or several) to which any of the
foregoing persons may become subject, under the Securities Act, the Exchange Act
or other federal or state law, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereto) arise out of or

                                      48
<PAGE>

are based upon any Violation, in each case to the extent (and only to the
extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by such Holder expressly for use in connection
with such registration; and each such Holder will pay any legal or other
expenses reasonably incurred by any person intended to be indemnified pursuant
to this subsection 16.8(b), in connection with investigating or defending any
such loss, claim, damage, liability, or action; provided, however, that the
indemnity agreement contained in this subsection 16.8(b) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Holder, which consent
shall not be unreasonably withheld; provided, that, in no event shall Holder's
cumulative, aggregate liability under this subsection 16.8(b), under Section
16.8(d), or under such sections together, exceed the net proceeds received by
such Holder from the offering out of which such Violation arises.

     (c)  Promptly after receipt by an indemnified party under this Section 16.8
of notice of the commencement of any action (including any governmental action),
such indemnified party will, if a claim in respect thereof is to be made against
any indemnifying party under this Section 16.8, deliver to the indemnifying
party a written notice of the commencement thereof and the indemnifying party
shall have the right to participate in, and, to the extent the indemnifying
party so desires, jointly with any other indemnifying party similarly noticed,
to assume the defense thereof with one counsel mutually satisfactory to the
parties; provided, however, that an indemnified party (together with all other
indemnified parties which may be represented without conflict by one counsel)
shall have the right to retain one separate counsel, with the fees and expenses
to be paid by the indemnifying party, if representation of such indemnified
party by the counsel retained by the indemnifying party would be inappropriate
due to actual or potential differing interests between such indemnified party
and any other party represented by such counsel in such proceeding.  The failure
to deliver written notice to the indemnifying party within a reasonable time of
the commencement of any such action shall not relieve such indemnifying party of
any liability to the indemnified party under this Section 16.8 unless the
failure to deliver notice is materially prejudicial to its ability to defend
such action.  Any omission to so deliver written notice to the indemnifying
party will not relieve it of any liability that it may have to any indemnified
party otherwise than under this Section 16.8.

     (d)  If the indemnification provided for in this Section 16.8 is held by a
court of competent jurisdiction to be unavailable to an indemnified party with
respect to any loss, liability, claim, damage, or expense referred to herein,
then the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage, or expense in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party on the one hand, and of the indemnified party on the other, in connection
with the statements or omissions that resulted in such loss, liability, claim,
damage, or expense as well as any other relevant equitable considerations.  The
relative fault of the indemnifying party and of the indemnified party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the indemnifying party or by the indemnified
party and the parties' relative intent,

                                      49
<PAGE>

knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

     (e)  Notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered
into in connection with the underwritten public offering are in conflict with
the foregoing provisions, the provisions in the underwriting agreement shall
control.

     (f)  The obligations of the Company and Holders of Registrable Securities
under this Section 16.8 shall survive the completion of any offering of
Registrable Securities in a registration statement under this Article XVI, and
otherwise.

          SECTION 16.9   Reports under the Exchange Act.  With a view to making
                         ------------------------------
available to the Holders of Registrable Securities the benefits of Rule 144
promulgated under the Securities Act and any other rule or regulation of the
Commission that may at any time permit a Holder to sell securities of the
Company to the public without registration or pursuant to a registration on Form
S-3, the Company agrees to:

     (a)  make and keep public information available, as those terms are
understood and defined in Rule 144, at all times after 90 days after the
effective date of the first registration statement filed by the Company for the
offering of its securities to the general public;

     (b)  take such action, including the voluntary registration of its
securities under Section 12 of the Exchange Act, as is necessary to enable the
Holders of Registrable Securities to utilize Form S-3 for the sale of their
Registrable Securities, such action to be taken as soon as practicable after the
end of the fiscal year in which the first registration statement filed by the
Company for the offering of its securities to the general public is declared
effective;

     (c)  file with the Commission in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act;
and

     (d)  furnish to any Holder, so long as the Holder owns any Registrable
Securities, forthwith upon request (i) a written statement by the Company that
it has complied with the reporting requirements of Rule 144 (at any time after
90 days after the effective date of the first registration statement filed by
the Company), the Securities Act and the Exchange Act (at any time after it has
become subject to such reporting requirements), or that it qualifies as a
registrant whose securities may be resold pursuant to Form S-3 (at any time
after it so qualifies), (ii) a copy of the most recent annual or quarterly
report of the Company and such other reports and documents so filed by the
Company, and (iii) such other information as may be reasonably requested in
availing any Holder of any rule or regulation of the Commission which permits
the selling of any such securities without registration or pursuant to such
form.

          SECTION 16.10  Assignment of Registration Rights.  The rights to cause
                         ---------------------------------
the Company to register Registrable Securities pursuant to this Article XVI may
be assigned (but only with all related obligations) by a Holder to, (i) in the
case of any Holder that is a partnership, limited liability company or Company,
any current and former constituent partners,

                                      50
<PAGE>

members, holders, affiliate funds and affiliates of that Holder, or (ii) in the
case of any Holder, (x) a transferee or assignee of such securities who, after
such assignment or transfer, holds at least 1% of the Fully Diluted Percentage
Interest at the time of the transfer as appropriately adjusted for all splits,
dividends, combinations, reclassifications and other like transactions of the
Registrable Securities originally held by such transferring Holder, or all of
such transferring Holder's Units if a lesser amount is transferred, (y) a
transferee or assignee who is a spouse, lineal descendant, father, mother,
brother or sister (each, a "Family Member") of Holder or (z) or to a trust, the
                            -------------
beneficiaries of which are exclusively the Holder and/or Family Members,
provided, in each case, that: (a) the Company is, within a reasonable time after
--------                ----
such transfer, furnished with written notice of the name and address of such
transferee or assignee and the securities with respect to which such
registration rights are being assigned; (b) such transferee or assignee agrees
in writing to be bound by and subject to the terms and conditions of this
Agreement, including without limitation the provisions of Section 16.11 below;
and (c) such assignment shall be effective only if immediately following such
transfer the further disposition of such securities by the transferee or
assignee is restricted under the Securities Act. For the purposes of determining
the number of Units of Registrable Securities held by a transferee or assignee
of a holder of Registrable Securities, the holdings of "affiliates" (as defined
in Rule 405 under the Securities Act) of such holder, affiliated partnerships,
constituent or retired partners of such partnerships (as well as Family Members
of such partners or spouses who acquire Registrable Securities by gift, will or
intestate succession) shall be aggregated together and with such partnership and
its affiliated partnerships and other entities; provided, that, all assignees
and transferees who would not qualify individually for assignment of
registration rights shall have a single attorney-in-fact for the purpose of
exercising any rights, receiving notices or taking any action under this Section
16.10.

          SECTION 16.11  "Market Stand-Off" Agreement.  Each Holder hereby
                         ----------------------------
agrees that, during the period of duration specified by the Company and an
underwriter of securities of the Company, following the effective date of the
registration statement of the Company filed under the Securities Act relating to
its initial public offering, it shall not, to the extent requested by the
Company and such underwriter, directly or indirectly sell, offer to sell,
contract to sell (including, without limitation, any short sale), grant any
option to purchase or otherwise transfer or dispose of (other than to donees who
agree to be similarly bound) any securities of the Company held by it at any
time during such period except securities included in such registration;
provided, however, that:

     (a)  the Company uses its best efforts to insure that officers and
directors of the Company enter into similar agreements;

     (b)  the Company uses its best efforts to obtain from persons who hold
greater than five percent (5%) of the Company's Units, a lock-up agreement
similar to that set forth in this Section 16.11; and

     (c)  such market stand-off time period shall not exceed 180 days.

Each Holder of Registrable Securities agrees to provide to the other
underwriters of any public offering such further agreements as such underwriter
may reasonably request in connection with

                                      51
<PAGE>

this market stand-off agreement, provided that the terms of such agreements are
substantially consistent with the provisions of this Section 16.11. In order to
enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the Registrable Securities of each Holder (and the
securities of every other person subject to the foregoing restriction) until the
end of such period.

Notwithstanding the foregoing, the obligations described in this Section 16.11
shall not apply to a registration relating solely to employee benefit plans on
Form S-1 or Form S-8 or similar forms which may be promulgated in the future, or
a registration relating solely to a Rule 145 transaction.

          SECTION 16.12  Termination of Registration Rights.  The right of any
                         ----------------------------------
Holder of Registrable Securities to request registration or to include
Registrable Securities in any registration pursuant to this Article XVI shall
terminate upon the earlier of (i) the date which is five years after the date
immediately prior to the closing of a Qualified IPO, or (ii) such date as a
public trading market shall exist for the Company's securities and all
Registrable Securities beneficially owned and subject to Rule 144 aggregation by
such Holder of Registrable Securities may immediately be sold under Rule 144
(without regard to Rule 144(k)) during any 90-day period, provided that such
Holder is not then an "affiliate" of the Company within the meaning of Rule 144
and such Holder owns less than 1% of the Units.

          SECTION 16.13  Limitations on Subsequent Registration Rights.  From
                         ---------------------------------------------
and after the date of this Agreement, the Company shall not, without the prior
written consent of Amerigon, enter into any agreement with any existing Holder
or prospective holder of Securities of the Company granting registration rights
with respect to such Securities, unless under the terms of such agreement, such
holder or prospective holder may include such securities in any such
registration only to the extent that the inclusion of his securities will not
reduce the amount of the Registrable Securities of the Holders of Registrable
Securities which is included.

                     ARTICLE XVII  --   GENERAL PROVISIONS
                     -----------------  ------------------

          SECTION 17.1   Amendment.  Any amendment of the Certificate of
                         ---------
Formation or this Agreement shall require the approval of a Majority in
Interests of all Members; provided, however that (i) any amendment to Article IV
                          --------
shall require the approval of the Class A Member, (ii) any amendment to Article
V shall require the approval of the Series A Member, (iii) any amendment to
Sections 3.5(a), 6.2, 6.6, 14.2 and 17.1 and Articles X, XV and XVI shall
require the approval of the Class A Member and the Series A Member, (iv) any
amendment to Section 3.2 and the second sentence of Section 11.1 shall require
the approval of all Members and (v) similar voting requirements shall apply to
any defined term used in any section or article referenced above to the extent
such term is material to the application of such section or article.

          SECTION 17.2   Waivers Generally.  No delay in the exercise of any
                         -----------------
right shall operate as a waiver of such right.  No single or partial exercise of
any right shall preclude its further exercise.  A waiver of any right on any one
occasion shall not be construed as a bar to, or waiver of, any such right on any
other occasion.

          SECTION 17.3   Equitable Relief.  If any Member proposes to Transfer
                         ----------------
its Membership Interest in violation of the terms of this Agreement, the Company
or any Member may apply to any court of competent jurisdiction for an injunctive
order prohibiting such proposed Transfer except upon compliance with the terms
of this Agreement, and the Company or any Member may institute and maintain any
action or proceeding against the Person proposing to make such Transfer to
compel the specific performance of this Agreement.  Any attempted Transfer in
violation of this Agreement is null and void, and of no force and effect.  The
Person against whom such action or proceeding is brought waives the claim or
defense that an adequate remedy at law exists, and such Person shall not urge in
any such action or proceeding the claim or defense that such remedy at law
exists.

          SECTION 17.4   Remedies for Breach.  The rights and remedies of the
                         -------------------
Members set forth in this Agreement are neither mutually exclusive nor exclusive
of any right or remedy provided by law, in equity or otherwise.  The Members
agree that all legal remedies (such as monetary damages) as well as all
equitable remedies (such as specific performance) shall be available for any
breach or threatened breach of any provision of this Agreement.

          SECTION 17.5   Costs.  If the Company or any holder of a Membership
                         -----
Interest retains counsel for the purpose of enforcing or preventing the breach
or any threatened breach of any provision of this Agreement or for any other
remedy relating to it, then the prevailing party shall be entitled to be
reimbursed by the nonprevailing party for all costs and expenses so incurred
(including reasonable attorney's fees, costs of bonds, and fees and expenses for
expert witnesses).

          SECTION 17.6   Counterparts.  This Agreement may be signed in multiple
                         ------------

Member may give by notice to the Company and all other Members, with such copies
to such parties as are indicated on Schedule [B] hereto. Any notices given to
any Member in accordance with this Agreement shall be deemed to have been duly

days after being sent by mail, postage prepaid, (c) the date of receipt, if sent
by registered or certified mail, postage prepaid, (d) when sent by confirmed
facsimile or telecopier transmission (provided a confirming copy is sent by
another means described herein), or (e) one Business Day after having been sent
by a recognized overnight courier service upon confirmation of delivery by such
courier service.

          SECTION 17.8   Date of Performance.  Whenever this Agreement provides
                         -------------------
for any action to be taken on a day which is not a Business Day, such action
shall be taken on the next following Business Day.

          SECTION 17.9   Limited Liability.  The liability of each Member,
                         -----------------
holder of a Membership Interest who is not a Member, Officer or agent of the
Company shall be limited as

                                      53
<PAGE>

set forth in this Agreement, the DLLCA, and other applicable law. No Member,
holder of a Membership Interest who is not a Member, Officer or agent of the
Company is liable for any debts, obligations or liabilities of the Company or
each other, whether arising in tort, contract or otherwise, solely by reason of

Company, or acting (or omitting to act) in such capacities or participating (as
an employee, consultant, contractor or otherwise) in the conduct of the business
of the Company, except that a Member shall remain personally liable for the
payment of such Member's Capital Contribution and as otherwise set forth in this
Agreement, the DLLCA, and other applicable law.

          SECTION 17.10  Partial Invalidity.  Wherever possible, each provision
                         ------------------
of this Agreement shall be interpreted in such a manner as to be effective and
valid under applicable law.  However, if for any reason any one or more of the
provisions of this Agreement are held to be invalid, illegal or unenforceable in
any respect, such action shall not affect any other provision of this Agreement.
In such event this Agreement shall be construed as if such invalid, illegal, or
unenforceable provision had never been contained in it.

          SECTION 17.11  Entire Agreement.  This Agreement contains the entire
                         ----------------
agreement among the Members with respect to the subject matter of this Agreement
and supersedes each course of conduct previously pursued or acquiesced in, and
each oral agreement and representation previously made, by the Members with
respect thereto, whether or not relied or acted upon.  Without limiting the
generality of the foregoing, this Agreement amends and restates the Prior
Operating Agreement of the Company made as of August 29, 2000, and subsequent
and amendments thereto, which is hereby superseded.

          SECTION 17.12  Benefit.  The contribution obligations of each Member
                         -------
shall inure solely to the benefit of the other Members and the Company, without
conferring on any other Person any rights of enforcement or other rights.

          SECTION 17.13  Binding Effect.  This Agreement is binding upon, and

the customers, vendors, trade secrets, methods, processes, procedures or any
other confidential business information of the Company or any other party to

Agreement, without the prior written consent of the Board.

     (b)  The parties further acknowledge and agree that in the event of a
breach or threatened breach of this Section 17.14, the Company may have no
adequate remedy in money damages and, accordingly, may be entitled to
appropriate injunctive relief against such breach or threatened breach. The
obligations contained in this Section 17.14 shall survive the cancellation or
other termination of this Agreement.

                                      54
<PAGE>

     (c)  This Section 17.14 shall not prevent any disclosure of information to
the extent required by applicable law or regulation or self-regulating
organization.  Any party required to make such disclosure, to the extent
reasonably practicable, shall (i) afford the Company the opportunity to seek to
prevent such disclosure or obtain an appropriate protective order or other
relief and (iii) cooperate with the Company's efforts to do so.

          SECTION 17.15  Covenants Not to Compete.  The Class A Member hereby
                         ------------------------
covenants with the Company and each other Member that on the Transfer of all or
substantially all of the Class A Member's Membership Interest, whether
voluntary, involuntary, by operation of law, or by reason of any provision of
this Agreement, the Class A Member shall not, directly or indirectly, through an
Affiliate or otherwise, within 50 miles of any established business office of
the Company, or elsewhere where the Company conducts its business, for a period
of eighteen months following the date of the Transfer, (a) enter into any
agreement or understanding, written or oral, relating to the services of any
employee of the Company, (b) solicit the business of, enter into any agreement,
written or oral, or otherwise deal with the customers of the Company, who were
such at the time of the Transfer and where the Company's contract or
relationship with such customer originated while the Class A Member was a Member
of the Company, or (c) use or disclose in any manner any confidential
information.

          SECTION 17.16  Further Assurances.  Each Member agrees, without
                         ------------------
further consideration, to sign and deliver such other documents of further
assurance as may reasonably be necessary to effectuate the provisions of this
Agreement.

                         -----
have the meanings specified, applicable to both singular and plural forms, for
all purposes of this Agreement.  All pronouns (and any variation) shall be
deemed to refer to the masculine, feminine or neuter, as the identity of the
Person may require.  The singular or plural includes the other, as the context
requires or permits.  The word include (and any variation) is used in an
illustrative sense rather than in a limiting sense.  The word day means a
calendar day, unless otherwise specified.

                         --------------------------------------
shall be governed by, and construed in accordance with, the laws of the State of

                                  Milestones
                                  ----------

Below are the broad milestones that, if achieved by January 2003, (1)
demonstrate significant advancement in thermoelectric technology and (2)
represent an application with revenue potential that is a multiple of the
initial $2,000,000 capital investment in BSST.

     1.   Demonstrate a minimum of 30% improvement in Coefficient of Performance
          in cooling, when compared to best practice thermoelectric systems from
          Ferrotec, Marlow and Melcor (each recognized as a leader in
          thermoelectrics) as of January 2001 ("Base Time").

          A. The improvement shall have a demonstrated theoretical basis and
             exhibit mechanical differences when compared to Base Time devices
             that cause the performance change.

          B. The improvement shall be demonstrated with both systems employing
             thermoelectric materials with the same Z (thermoelectric
             coefficient of performance) and at the same temperature change,
             ambient temperature and cooling power output.

     2.   Construct and demonstrate a breadboard power generator that when used
          in a co-generation cycle, has 30% greater thermodynamic efficiency
          than thermoelectric power generators as of Base Time, and has 30% less
          waste heat flow to the cold side when used as a stand-alone device.

          A. Device shall produce 1000 watts power minimum from a heat source
             maintained at 475C and a cold side maintained at 50C, so as to
             approximate the operating conditions of a heat source such as an
             automobile catalytic converter.

          B. The improvement shall be demonstrated with both systems employing
             thermoelectric materials with the same Z (thermoelectric
             coefficient of performance) and at the same temperature change,
             ambient temperature and electrical power output.

The Board of Directors shall determine if the Milestones have been met, and may
use experts in thermodynamics to independently verify the experimental results.
