 LONG TERM INCENTIVE PLAN AND EXECUTIVE LONG TERM INCENTIVE
                    PLAN TRUST AGREEMENT

TRUST UNDER: MILLENNIUM CHEMICALS INC. LONG TERM INCENTIVE
             PLAN AND EXECUTIVE LONG TERM INCENTIVE PLAN

          This Agreement made this first day of January,
1999 by and between Millennium America Holdings Inc. (the
"Company") and George H. Hempstead, III (the "Trustee");

          WHEREAS, Company has adopted the Millennium
Chemicals Inc. Long Term Incentive Plan and the Millennium
Chemicals Inc. Executive Long Term Incentive Plan
(individually and collectively, the "Plan");

          WHEREAS, Company has incurred or expects to incur
liability under the terms of such Plan with respect to
individuals participating in such Plan;

          WHEREAS, Company wishes to establish a trust (the
"Trust") and to contribute to the Trust assets that shall be
held therein;

          WHEREAS, it is the intention of the parties that
this Trust shall constitute an unfunded arrangement and
shall not affect the status of the Plan as an unfunded plan
maintained for the purpose of providing deferred
compensation for certain key employees of the Company and
certain of its subsidiaries, and such Plan is not intended
to be subject to the Employee Retirement Income Security Act
of 1974.

          WHEREAS, it is the intention of the Company to
make contributions to the Trust to provide itself with a
source of funds to assist in the meeting of its liabilities
under the Plan while still maintaining the ability to use
the Trust assets for general corporate needs;

          NOW, THEREFORE, the parties do hereby establish
the Trust and agree that the Trust shall be comprised, held
and disposed of as follows:

Section 1.  Establishment of Trust

(a)  The Company hereby deposits with the Trustee in trust
such cash and/or marketable securities, if any, listed in
Appendix A, which shall become the principal of the Trust to
be held, administered and disposed of by the Trustee as
provided in this Trust Agreement.

(b)  The Trust hereby established shall be revocable by the
Company; provided, however, that the Trust shall become
irrevocable upon a Change in Control (as defined in Section
12(f) below).

(c)  The Trust is intended to be a grantor trust, of which
the Company is the grantor, within the meaning of subpart E,
subchapter J, chapter 1, subtitle A of the Internal Revenue
Code of 1986, as amended (the "Code"), and shall be
construed accordingly.

(d)  The Company, in its sole discretion, may at any time,
or from time to time, make additional deposits of cash or
other property (including shares of common stock ($.01 par
value) of the Company ("Shares")) in trust with the Trustee
to augment the principal to be held, administered and
disposed of by the Trustee as provided in this Trust
Agreement.  Except to the extent provided in Section 1(f)
below, neither the Trustee nor any Plan participant or
beneficiary shall have any right to compel such additional
deposits.

(e)  Trustee shall not be obligated to receive such cash/or
property unless prior thereto Trustee has agreed that such
cash and/or property is acceptable to Trustee and Trustee
has received such reconciliation, allocation, investment or
other information concerning, or representation with respect
to, the cash and/or property as Trustee may require.
Trustee shall have no duty or authority to (a) require any
deposits to be made under the Plan or to the Trustee, (b)
compute any amount to be deposited under the Plan to the
Trustee, or (c) determine whether amounts received by
Trustee comply with the Plan.  Assets of the Trust may, in
Trustee's discretion, be held in an account with an
affiliate of Trustee.

(f)  Upon a Change in Control, as defined in Section 12(f)
below, the Company shall, as soon as possible, but in no
event longer than thirty (30) days following the Change in
Control, make an irrevocable contribution to the Trust in an
amount that is sufficient to pay each Plan participant (or
beneficiary) the benefits to which Plan participants (or
their beneficiaries) who have Awards under the Plan would be
entitled pursuant to the terms of the Plan as of the date on
which the Change in Control occurred.

Section 2.  Payments to Plan Participants and Their
Beneficiaries.

(a)  With respect to each Plan participant, the Company
shall direct the Trustee as to the form and amount to be
paid (as provided for or available under the Plan) to the
participant (and his or her beneficiaries) and the time of
commencement for payment of such amounts.  The Company shall
make provisions for the reporting and withholding of any
federal, state or local taxes that may be required to be
withheld with respect to payment of benefits pursuant to the
terms of the Plan and shall pay amounts withheld by the
Trustee to the appropriate taxing authorities or determine
that such amounts have been reported, withheld and paid by
the Company, it being understood among the parties hereto
that (1) the Company shall on a timely basis provide the
Trustee specific information as to the amount of taxes to be
withheld and (2) the Company shall be obligated to receive
such withheld taxes from the Trustee and properly pay and
report such amounts to the appropriate taxing authorities.

(b)  The entitlement of Plan participants or his or her
beneficiaries to benefits under the Plan shall be determined
by the Company or such party as it shall designate under the
Plan, and any claim for such benefits shall be considered
and reviewed under the procedure set out in the Plan.

(c)  The Company may make payment of benefits directly to
the Plan participants or their beneficiaries as they become
due under the terms of the Plan.  The Company shall notify
Trustee of its decision to make payments of benefits
directly prior to the time amounts are payable to
participants or their beneficiaries.  In addition, if the
principal of the Trust, and any earnings thereon, are not
sufficient to make payments of benefits in accordance with
the terms of the Plan, the Company shall make the balance of
each payment as it falls due.  The Trustee shall notify the
Company where principal and earnings are not sufficient.

(d)  The Trustee shall have no responsibility to determine
whether the Trust is sufficient to meet the liabilities
under the Plan, and shall not be liable for payments or Plan
liabilities in excess of the Trust assets.

Section 3.  Payment to the Company.

  Upon a Change in Control, in accordance with Section 1(b)
hereof, the Company shall have no rights or power to direct
the Trustee to return to the Company or to divert to others
any of the Trust assets before all payment of benefits have
been made to Plan participants and their beneficiaries
pursuant to the terms of the Plan.

Section 4.  Investment Authority.

(a)  The Trustee may invest in securities (including stock
or rights to acquire stock) or obligations issued by the
Company.  All rights associated with assets of the Trust
shall be exercised by the Trustee or the person designated
by the Trustee, and shall in no event be exercised by or
rest with Plan participants, except that voting rights with
respect to Trust assets will be exercised by the Trustee.
The Trustee, however, acknowledges the desire of the Company
that the Trust corpus be invested primarily (if not
exclusively) in Shares and the Company and acknowledges that
any diversification of investments that otherwise might be
required of a trustee under applicable state law is hereby
waived.

(b)  The Company shall have the right at anytime, and from
time to time in its sole discretion, to substitute assets of
equal fair market value for any asset held by the Trust.
This right is exercised by the Company in a nonfiduciary
capacity without the approval or consent of any person in a
fiduciary capacity.

(c)  With the express, written consent of the Company, the
Trustee may appoint one or more investment advisors who are
registered as investment advisers under the Investment
Advisers Act of 1940 to provide investment advice on a
discretionary or non-discretionary basis with respect to all
or a specified portion of the assets of the Trust.

(d)  The Trustee, or the Trustee's designee, is authorized
and empowered:

          (1)  To invest and reinvest Trust assets, together with
            income therefrom, in common stock, preferred stock,
            convertible preferred stock, bonds, debentures, convertible
            debentures and bonds, mortgages, notes, commercial paper and
            other mutual funds, guaranteed investment contracts, bank
            investment contracts, other securities, policies of life
            insurance, annuity contracts, options to buy or sell
            securities or other assets, and all other property of any
            type (personal, real or mixed, and tangible or intangible);

          (2)  To deposit or invest all or any part of the assets of
            the Trust in savings accounts or certificates of deposit or
            other deposits in a bank or savings and loan association or
            other depository institution;

          (3)  To hold, manage, improve, repair and control all
            property, real or personal, forming part of the Trust; to
            sell, convey, transfer, exchange, partition, lease for any
            term, even extending beyond the duration of this Trust, and
            otherwise dispose of the same from time to time;

          (4)  To hold in cash, without liability for interest, such
            portion of the Trust as is pending investments, or payments
            of expenses, or the distribution of benefits;

          (5)  To take such action as may be necessary or desirable to
            protect the Trust from loss due to the default on mortgages
            held in the Trust including the appointment of agents or
            trustees in such other jurisdictions as may seem desirable,
            to transfer property to such agents or trustees, to grant to
            such agents such powers as are necessary or desirable to
            protect the Trust, to direct such agent or trustee, or to
            delegate such power to direct, and to remove such agent or
            trustee;

          (6)  To settle, compromise, or abandon all claims and
            demands in favor or against the Trust;

          (7)  Except as otherwise provided herein, to exercise all of
            the further rights, powers, options and privileges granted,
            provided for, or vested in trustees generally under the laws
            of the state of New Jersey as set forth above, so that the
            powers conferred upon the Trustee herein shall not be in
            limitation of any authority conferred by law, but shall be
            in addition thereto;

          (8)  To borrow money from any source and to execute
            promissory notes, mortgages or other obligations and to
            pledge or mortgage any trust asset as security; and

          (9)  To maintain accounts at, execute transactions through,
            and lend on an adequately secure basis stocks, bonds, or
            other securities to any brokerage or other firm.

Section 5.  Additional Powers of the Trustee.

  To the extent necessary or which it deems appropriate to
implement its powers under Section 4 or otherwise to fulfill
any of its duties and responsibilities as Trustee of the
Trust, the Trustee shall have the following additional
powers and authority:

(a)  To register securities, or any other property, in its
name with or without indication of the capacity in which
property shall be held, or to hold securities in bearer form
and to deposit any securities or other property in a
depository or clearing corporation;

(b)  To designate and engage the service of, and to delegate
powers and responsibilities to, such agents,
representatives, advisors, counsel and accountants as the
Trustee considers necessary or appropriate, and as part of
its expenses under this Trust Agreement, to pay their
reasonable expenses and compensation;

(c)  To make, execute and deliver, as Trustee, any and all
deeds, leases, mortgages, conveyances, waivers, releases or
other instruments in writing necessary or appropriate for
the accomplishment of any of the powers listed in this Trust
Agreement; and

(d)  Generally to do all other acts which the Trustee deems
necessary or appropriate for the protection of the Trust.

Section 6.  Disposition of Income.

  During the term of this Trust, all income received by the
Trust, net expenses and taxes, shall be accumulated and
reinvested principally in Shares unless otherwise instructed
by the Trustee.

Section 7.  Responsibility and Indemnity of the Trustee.

(a)  The Trustee shall act with the care, skill, prudence
and diligence under the circumstances then prevailing that a
prudent person acting in like capacity and familiar with
such matters would use in the conduct of an enterprise of a
like character and with like aims; provided, however, that
to the extent the Trust corpus is invested in Shares, the
Trustee need not satisfy any diversification of investments
requirement at law or in equity; and, further provided, that
the Trustee shall incur no liability to any person for any
action taken pursuant to a direction, request or approval
given by the Company which is contemplated by, and in
conformity with, the terms of the Plan and this Trust and is
given in writing by the Company.  The Trustee shall also
incur no liability to any person for any failure to act in
the absence of direction, request or approval from the
Company which is contemplated by, and in conformity with,
the terms of this Trust.  In the event of a dispute between
the Company and a party, the Trustee may apply to a court of
competent jurisdiction to resolve the dispute.

(b)  The Company hereby indemnifies the Trustee against, and
shall hold them harmless from, any and all loss, claims,
liability, and expense, including reasonable attorneys'
fees, imposed upon or incurred by the Trustee as a result of
any acts taken, or any failure to act, in accordance with
the directions from the Company or any designee of the
Company, or by reason of the Trustee's good faith execution
of its duties with respect to the Trust, including, but not
limited to, its holding of assets of the Trust, the
Company's obligations in the foregoing regard to be
satisfied promptly by the Company, provided that in the
event the loss, claim, liability or expense involved is
determined by a no longer appealable final judgment entered
in a lawsuit or proceeding to have resulted from the gross
negligence or willful misconduct of the Trustee, the Trustee
shall promptly on request thereafter return to the Company
any amount previously received by the Trustee under this
Section with respect to such loss, claim, liability or
expense.  If the Company does not pay such costs, expenses
and liabilities in a reasonably timely manner, Trustee may
obtain payment from the Trust without direction from the
Company.

(c)  The Trustee may consult with legal counsel (who may
also be counsel for the Company generally) with respect to
any of its duties or obligations hereunder.

(d)  The Trustee may hire agents, accountants, actuaries,
investment advisers, financial consultants or other
professionals to assist it in performing any of its duties
or obligations hereunder.

(e)  The Trustee shall have, without exclusion, all powers
conferred on the Trustee by applicable law, unless expressly
provided otherwise herein, provided, however, that if an
insurance policy is held as an asset of the Trust, the
Trustee shall have no power to name a beneficiary of the
policy other than the Trust, to assign the policy (as
distinct from conversion of the policy to a different form)
other than to a successor the Trustee, or to loan to any
person the proceeds of any borrowing against such policy.

(f)  However, notwithstanding the provisions of Section 9(e)
above, the Trustee may loan to the Company the proceeds of
any borrowing against an insurance policy held as an asset
of the Trust.

(g)  Notwithstanding any powers to the Trustee pursuant to
this Trust Agreement or to applicable law, the Trustee shall
not have any power that could give this Trust the objective
of carrying on a business and dividing the gains therefrom,
within the meaning of Section 301.7701-2 of the Procedure
and Administrative Regulations promulgated pursuant to the
Code.

Section 8.  Compensation and Expenses of Trustee.

The Company shall pay all administrative expenses, but if
not so paid, the expenses shall be paid from the Trust.

Section 9.  Resignation and Removal of Trustee.

(a)  The Trustee may resign at any time by written notice to
the Company, which shall be effective 60 days after receipt
of such notice unless the Company and the Trustee agree
otherwise.

(b)  The Trustee may be removed by the Company immediately
upon notice provided that the Company has appointed a
successor trustee effective immediately following the
removal of the Trustee.  If no such successor trustee has
been appointed, the Trustee may be removed by the Company on
60 days notice or upon shorter notice accepted by the
Trustee.

(c)  Upon resignation or removal of the Trustee and
appointment of a successor Trustee, all assets shall
subsequently be transferred to the successor Trustee.  The
transfer shall be completed within 60 days after receipt of
notice of resignation, removal or transfer, unless the
Company extends the time limit.

(d)  If the Trustee resigns or is removed, a successor shall
be appointed, in accordance with Section 10 hereof, by the
effective date or resignation or removal under paragraph(s)
(a) or (b) of this section.  If no such appointment has been
made, the Trustee may apply to a court of competent
jurisdiction for appointment of a successor or for
instructions.  All expenses of the Trustee in connection
with the proceeding shall be allowed as administrative
expenses of the Trust.

(e)  Upon settlement of the account and transfer of the
Trust assets to the successor Trustee, all rights and
privileges under this Trust Agreement shall vest in the
successor Trustee and all responsibility and liability of
the Trustee with respect to the Trust and assets thereof
shall terminate subject only to the requirement that Trustee
execute all necessary documents to transfer the Trust assets
to the successor Trustee.

Section 10.  Appointment of Successor.

(a)  If the Trustee resigns or is removed in accordance with
Section 9(a) or (b) hereof, the Company may appoint any
third party, such as a bank trust department or other party
that may be granted trustee powers under state law, as a
successor to replace the Trustee upon resignation or
removal. The appointment shall be effective when accepted in
writing by the new Trustee, who shall have all of the rights
and powers of the former Trustee, including ownership rights
in the Trust assets.  The former Trustee shall execute any
instrument necessary or reasonably requested by Company or
the successor Trustee to evidence the transfer.

(b)  The successor Trustee need not examine the records and
act of any prior Trustee and may retain or dispose of
existing Trust assets, subject to Section 6 hereof.  The
successor Trustee shall not be responsible for and the
Company shall indemnify and defend the successor Trustee
from any claim or liability resulting from any action or
inaction of any prior Trustee or from any other past event,
or any condition existing at the time it becomes successor
Trustee.

Section 11.  Amendment or Termination.

(a)  This Trust Agreement may be amended by a written
instrument executed by the Trustee and the Company.
Notwithstanding the foregoing, no such amendment shall
conflict with the terms of the Plan or shall make the Trust
revocable upon or after a Change in Control once the Trust
is irrevocable in accordance with Section 1(b) hereof.

(b)  The Trust shall not terminate until the date on which
Plan participants and their beneficiaries are no longer
entitled to benefits pursuant to the terms of the Plan.
Upon termination of the Trust any assets remaining in the
Trust shall be returned to the Company.

(c)  Upon written approval of participants or beneficiaries
entitled to payment of benefits pursuant to the terms of the
Plan, the Company may terminate this Trust prior to the time
all benefit payments under the Plan have been made.  All
assets in the Trust at termination shall be returned to
Company.

Section 12.  Miscellaneous.

(a)  Any provision of this Trust Agreement prohibited by law
shall be ineffective to the extent of any such prohibition,
without invalidating the remaining provisions hereof.

(b)  Benefits payable to Plan participants and their
beneficiaries under this Trust Agreement may not be
anticipated, assigned (either at law or in equity),
alienated, pledged, encumbered or subjected to attachment,
garnishment, levy, execution or other legal or equitable
process.

(c)  This Trust Agreement shall be governed by and construed
in accordance with the laws of the state of New Jersey.

(d)  The provisions of Sections 2(d), and 7(b) of this
Agreement shall survive termination of this Agreement.

(e)  The rights, duties, responsibilities, obligations and
liabilities of the Trustee are as set forth in this Trust
Agreement, and no provision of the Plan or any other
document shall affect such rights, responsibilities,
obligations and liabilities.  If there is a conflict between
provisions of the Plan and this Trust Agreement with respect
to any subject involving the Trustee, including but not
limited to the responsibility, authority or powers of the
Trustee, the provisions of this Trust Agreement shall be
controlling.

Millennium Chemicals Inc. ("Millennium"):

          (1)  any "person" as such term is used in Sections 13(d) and

            other fiduciary holding securities under any employee
            benefit Plan of Millennium or any company owned, directly or
            indirectly, by the stockholders of Millennium in
            substantially the same proportions as their ownership of
            Common Stock of Millennium), becoming the "beneficial owner"
            (as defined in Rule 13d-3 under the 1934 Act), directly or
            indirectly, of securities of Millennium representing twenty-
            five percent (25%) or more of the combined voting power of
            Millennium's then outstanding securities;

          (2)  during any period of two consecutive years (not
            including any period prior to October 1, 1996), individuals
            who at the beginning of such period constitute the Board of
            Directors of Millennium, and any new director (other than a
            director designated by a person who has entered into an
            agreement with Millennium to effect a transaction described
            in clause (1), (3), or (4) of this Section 12 (f) or a
            director whose initial assumption of office occurs as a
            result of either an actual or threatened election contest
            (as such terms are used in Rule 14a-11 of Regulation 14A
            promulgated under the 1934 Act) or other actual or
            threatened solicitation of proxies or consents by or on
            behalf of a person other than the Board of Directors of
            Millennium) whose election by the Board of Directors or
            nomination for election by Millennium's stockholders was
            approved by a vote of at least two-thirds of the directors
            then still in office who either were directors at the
            beginning of the two-year period or whose election or
            nomination for election was previously so approved, cease
            for any reason to constitute at least a majority of the
            Board of Directors;

          (3)  the merger or consolidation of Millennium with any
            other corporation, other than a merger or consolidation
            which would result in the voting securities of Millennium
            outstanding immediately prior thereto continuing to
            represent (either by remaining outstanding or by being
            converted into voting securities of the surviving entity)
            more than fifty percent (50%) of the combined voting power
            of the voting securities of Millennium or such surviving
            entity outstanding immediately after such merger or
            consolidation; provided, however, that a merger or
            consolidation effected to implement a recapitalization of
            Millennium (or similar transaction) in which no person
            (other than those covered by the exceptions in clause (1)
            above) acquires more than twenty-five percent (25%) of the
            combined voting power of Millennium's then outstanding
            securities shall not constitute a Change in Control; or

          (4)  the stockholders of Millennium approve a Plan of
            complete liquidation of Millennium or the closing of the
            sale or disposition by Millennium of all or substantially
            all of Millennium's assets other than the sale or
            disposition of all or substantially all of the assets of
            Millennium to one or more Subsidiaries (as defined below) of
            Millennium or to a person or persons who beneficially own,
            directly or indirectly, at least fifty percent (50%) or more
            of the combined voting power of the outstanding voting
            securities of Millennium at the time of the sale or
            disposition.  "Subsidiary" has the meaning set forth in
            Section 424(f) of the Code, as amended or superseded, and
            the term shall also include any partnership, limited
            liability company or other business entity if Millennium
            owns, directly or indirectly, securities or other ownership
            interests representing at least fifty percent (50%) of the
            ordinary voting power or equity or capital interests of such
            entity.  Notwithstanding any of the foregoing, the formation
            of Equistar Chemicals, LP ("Equistar") and the contribution
            of assets by Millennium Petrochemicals Inc. to Equistar on
            December 1, 1997 shall not constitute a Change in Control,
            and the sale or disposition of all or any part of the
            Company's interests in Equistar shall not constitute a
            Change in Control.

                         STOCKHOLDER RIGHTS AGREEMENT

          THIS STOCKHOLDER RIGHTS AGREEMENT is made as of January 31, 2001, by
and among InterTrust Technologies Corporation, a Delaware corporation (the
"Company") and Nokia Finance International B.V., a company organized under the
laws of The Netherlands ("Nokia"). This Agreement shall be effective upon the
consummation of the sale of shares of Common Stock by the Company to Nokia
pursuant to the terms of the Purchase Agreement (as hereinafter defined).

                                   RECITALS
                                   --------

          WHEREAS, the Company and Nokia are parties to that certain Common
Stock Purchase Agreement of even date herewith (the "Purchase Agreement")
pursuant to which Nokia will purchase shares of Common Stock of the Company;

          WHEREAS, the shares of Common Stock of the Company issued to Nokia
will be granted certain registration and other rights as set forth herein.

          NOW, THEREFORE, in consideration of the respective covenants and
agreements herein contained and for other good and valuable consideration (the
receipt and sufficiency of which is hereby acknowledged by each party), the
parties hereby covenant and agree as follows:

          1.   Registration Rights. The Company covenants and agrees as follows:
               -------------------

               1.1  Definitions. For purposes of this Section 1:
                    -----------

                    (a)  The term "Act" means the Securities Act of 1933, as
amended.

                    (b)  The term "Form S-3" means such form under the Act as in
effect on the date hereof or any registration form under the Act subsequently
adopted by the SEC that permits inclusion or incorporation of substantial
information by reference to other documents filed by the Company with the SEC.

                    (c)  The term "1934 Act" means the Securities Exchange Act
of 1934, as amended.

                    (d)  The term "register," "registered," and "registration"
refer to a registration effected by preparing and filing a registration
statement or similar document in compliance with the Act, and the declaration or
ordering of effectiveness of such registration statement or document.

                    (e)  The term "Registrable Securities" means the shares of
Common Stock sold to Nokia pursuant to the Purchase Agreement or pursuant to
Section 2.1 and

                                       1
<PAGE>

3.4 hereunder. As to any particular Registrable Securities that have been
issued, such securities shall cease to be Registrable Securities when (i) a
registration statement with respect to the sale of such securities shall have
become effective under the Securities Act and such securities shall have been
disposed of under such registration statement, (ii) such securities shall have
been distributed to the public pursuant to Rule 144 of the SEC under the
Securities Act, (iii) such securities shall have been otherwise transferred or
disposed of, and the subsequent transfer or disposition of such securities shall
not require their registration or qualification under the Securities Act or any
similar state law then in force or (iv) such securities shall have ceased to be
outstanding.

                    (f)  The term "SEC" shall mean the Securities and Exchange
Commission.

               1.2  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 stockholders other than Nokia) any of its stock or other securities
under the Act in connection with the public offering of such securities (other
than a registration relating solely to the sale of securities to participants in
a Company stock option, purchase or benefit plan, a registration relating to a
corporate reorganization or other transaction under Rule 145 of the Act, or a
registration in which the only Common Stock being registered is Common Stock
issuable upon conversion of debt securities that are also being registered), the
Company shall, at such time, promptly give Nokia written notice of such
registration. Upon the written request of Nokia given within twenty (20) days
after mailing of such notice by the Company in accordance with Section 3.9, the
Company shall, subject to the provisions of Section 1.2(c), use all reasonable
efforts to cause to be registered under the Act all of the Registrable
Securities that Nokia has requested to be registered. The Company shall be
entitled to appoint the underwriters and to designate their respective roles in
any offering under this Section 1.2 as well as to approve the syndicate
structure for any such offering.

                    (b)  Right to Terminate Registration. The Company shall have
                         -------------------------------
the right to terminate or withdraw any registration initiated by it under this
Section 1.2 prior to the effectiveness of such registration whether or not Nokia
has elected to include securities in such registration. The expenses of such
withdrawn registration shall be borne by the Company in accordance with Section
1.6 hereof.

                    (c)  Underwriting Requirements. In connection with any
                         -------------------------
offering involving an underwriting of shares of the Company's capital stock, the
Company shall not be required under this Section 1.2 to include any of Nokia's
securities in such underwriting unless Nokia accepts 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 enters into an
underwriting agreement in customary form with an underwriter or underwriters
selected by the Company, 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 stockholders to be included in such

                                       2
<PAGE>

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 of the offering, then the Company shall be required to include in the
offering only that number of such securities, including Registrable Securities,
that the underwriters determine in their sole discretion will not jeopardize the
success of the offering (the securities so included to be apportioned first to
the Company, then second pro rata among the selling holders of Common Stock
previously issued upon conversion of the Company's Series A Preferred Stock
according to the total amount of Common Stock previously issued upon conversion
of the Company's Series A Preferred Stock held by each selling holder, then
third pro rata among the selling holders of Common Stock previously issued upon
conversion of Preferred Stock other than Series A Preferred Stock according to
the total amount of Common Stock previously issued upon conversion of Preferred
Stock other than Series A Preferred Stock owned by each selling holder, then
fourth pro rata among all other selling stockholders, or in such other
proportions as shall mutually be agreed to by all such parties), it being
understood that all Registrable Securities may be excluded from the registration
on this basis. The affiliates through which Nokia may directly or indirectly own
any Registrable Securities and any trusts for the benefit of any of the
foregoing entities shall be deemed to be a single "selling stockholder," and any
pro rata reduction with respect to such "selling stockholder" shall be based
upon the aggregate amount of Registrable Securities owned by all entities
included in such "selling stockholder," as defined in this sentence.

               1.3  Demand Registration. At any time following nine (9) months
                    -------------------
from the date hereof, if the Company shall receive from Nokia a written request
or requests that the Company effect a registration and any related qualification
or compliance with respect to all or a part of the Registrable Securities owned
by Nokia, the Company shall:

                    (a)  use all reasonable efforts to effect, in accordance
with the provision of Section 1.4 below, 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 Nokia's
Registrable Securities as are specified in such request, together with all or
such portion of the Registrable Securities of any other stockholders joining in
such request as are specified in a written request given within fifteen (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 1.3:

                         (i)    within ninety (90) days of a public offering of
the Company's securities;

                         (ii)   if Nokia, together with the holders of any other
securities of the Company entitled to inclusion in such registration, proposes
to sell Registrable Securities and such other securities (if any) at an
aggregate price to the public (net of any underwriters' discounts or
commissions) of less than $5,000,000;

                         (iii)  if the Company shall furnish to Nokia a
certificate signed by the Chief Executive Officer or Chairman of the Board of
the Company stating that in the good faith judgment of the Board of Directors of
the Company, it would (because of the existence of, or in anticipation of, any
acquisition or financing activity, or the unavailability for

                                       3
<PAGE>

reasons beyond the Company's control of any required financial statements, or
any other event or condition of significance to the Company) be significantly
disadvantageous (a "Disadvantageous Condition") to the Company for such
registration statement to be maintained effective or to be filed and become
effective, the Company shall be entitled to cause such registration statement to
be withdrawn and the effectiveness of such registration statement to be
terminated, or, in the event no registration statement has yet been filed, shall
be entitled not to file any such registration statement, in each case for up to
90 consecutive days, following which the Company shall be required to deliver a
new certificate of the Chief Executive Officer to extend such period for up to
two additional periods of 30 days each, or, if sooner, until such
Disadvantageous Condition no longer exists (notice of which the Company shall
promptly deliver to Nokia) (provided, however, that the Company shall not
utilize this right more than once in any twelve month period) and, upon receipt
of any such notice of a Disadvantageous Condition, Nokia will forthwith
discontinue use of the prospectus contained in such registration statement and,
if so directed by the Company, Nokia will deliver to the Company all copies,
other than permanent file copies then in Nokia's possession, of the prospectus
then covering such Registrable Securities current at the time of receipt of such
notice, and, in the event no registration statement has yet been filed, all
drafts of the prospectus covering such Registrable Securities. Upon termination
of such Disadvantageous Condition, the Company will, if requested by Nokia, use
all reasonable efforts to file such registration statement as promptly as
practicable, but in any event within 60 days of such termination. If the Company
declines to file a registration statement in accordance with this Section or
withdraws such registration statement, then the submission of a Registration
Request, or the election to participate in the proposed offering shall not
constitute the exercise of a Registration Request by Nokia. The six-month period
referred to in Section 1.4(a), during which the registration statement must be
kept current after its effective date, shall be extended for an additional
number of business days equal to the number of business days during which the
right to sell Registrable Securities was suspended pursuant to this Section);

                         (iv)   if the Company has already effected three (3)
registrations at the request of Nokia (and/or its permitted tranferees) pursuant
to this Section 1.3 or more than one (1) such registration on Form S-1 or more
than two (2) other such registrations in any twelve (12) month period;

                         (v)    unless such Registrable Securities are sold
pursuant to a firmly underwritten offering;

                         (vi)   in any particular jurisdiction in which the
Company would be required to qualify to do business or to execute a consent to
general service of process in effecting such registration, qualification or
compliance;

                    (b)  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, but in any event within 60
days after receipt of the request.

                                       4
<PAGE>

                    (c)  The Company and Nokia shall in mutual agreement appoint
the underwriters and designate their respective roles in any offering under this
Section 1.3 as well as approve the syndicate structure for any such offering.

               1.4  Obligations of the Company. Whenever required under this
                    --------------------------
Section 1 to effect the registration of any Registrable Securities, the Company
shall, as expeditiously as reasonably possible:

                    (a)  prepare and file with the SEC a registration statement
with respect to such Registrable Securities within the time period specified in
Section 1.3(b) above and use all reasonable efforts to cause such registration
statement to become effective, and, upon the request of the holders of a
majority of the Registrable Securities registered thereunder, keep such
registration statement effective for a period of up to ninety (90) days or, if
earlier, until the distribution contemplated in the Registration Statement has
been completed;

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

                    (c)  furnish to Nokia such numbers of copies of the
registration statement and each amendment and/or supplements thereto and the
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Act, and such other documents as they may reasonably request
in order to facilitate the disposition of Registrable Securities owned by it;

                    (d)  use all reasonable 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 Nokia,
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;

                    (e)  enter into customary agreements, including in the event
of any underwritten public offering, an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering and take such
other actions as are reasonably required in order to expedite or facilitate the
disposition of the Registrable Securities;

                    (f)  after the filing of the registration statement,
promptly notify Nokia of any stop order issued or threatened by the SEC and take
all reasonable actions required to prevent the entry of such stop order or to
remove it if entered;

                    (g)  notify Nokia at any time when a prospectus relating to
Registrable Securities covered by a registration statement is required to be
delivered under the 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

                                       5
<PAGE>

not misleading in the light of the circumstances then existing and at the
request of Nokia prepare and furnish to Nokia a reasonable number of copies of a
supplement to or an amendment of such prospectus as may be necessary so that, as
thereafter delivered to the purchasers of such Registrable Securities or
securities, such prospectus shall not include an untrue statement of a material
fact or omit 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;

                    (h)  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;

                    (i)  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;

                    (j)  otherwise use its best efforts to comply with all
applicable rules and regulations of the SEC, and make available to its security
holders, as soon as reasonably practicable, but in no event more than eighteen
months after the effective date of such registration statement, an earnings
statement covering a period of at least twelve months after the effective date
of such registration statement, which earnings statement shall satisfy the
provisions of Section 11(a) of the Securities Act;

                    (k)  in case of a demand registration pursuant to Section
1.3 hereof, furnish to the underwriters, and use reasonable commercial efforts
to furnish to Nokia, the following letters:

                         (A)  a signed counterpart of an opinion of counsel for
the Company, dated the date of the closing under the underwriting agreement,
covering such matters as the managing underwriters of such offering may
reasonably request; and

                         (B)  a letter signed by the independent public accounts
who have certified the Company's financial statements included in the
registration statement, covering such matters as the managing underwriters of
such offering may reasonably request;

such letters shall be in the form as is customary for similar letters, so long
as such form is acceptable to the managing underwriters of such offering.

               1.5  Information from Nokia. It shall be a condition precedent to
                    ----------------------
the obligations of the Company to take any action pursuant to this Section 1
with respect to the Registrable Securities that Nokia 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 Registrable Securities.

               1.6  Expenses of Registration. All expenses other than
                    ------------------------
underwriting discounts and commissions incurred in connection with
registrations, filings or qualifications pursuant to Sections 1.2 and 1.3,
including (without limitation) all registration, filing and

                                       6
<PAGE>

qualification fees, printers' and accounting fees, fees and disbursements of
counsel for the Company shall be borne by the Company. Notwithstanding the
foregoing, the Company shall not be required to pay for any expenses of any
registration proceeding begun pursuant to Section 1.3 if the registration
request is subsequently withdrawn at the request of the holders of a majority of
the Registrable Securities to be registered (in which case all participating
holders shall bear such expenses pro rata based upon the number of Registrable
Securities that were to be requested in the withdrawn registration).

               1.7  Delay of Registration. Nokia shall not 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 Section 1.

               1.8  Rights of Certain Requesting Holders. The Company will not
                    ------------------------------------
file any registration statement pursuant to Section 1.3 hereof under the
Securities Act unless it shall first have given to Nokia as long as it owns
shares of its Common Stock constituting 10% or more of the Common Stock at the
time outstanding or is otherwise deemed to be a control person under the
Securities Act at least 15 days' prior written notice thereof and, if so
requested by Nokia within 5 days after such notice, Nokia shall have the right,
if Nokia, based on an opinion of legal counsel, concludes that it will be deemed
to be a controlling person of the Company within the meaning of the Securities
Act, (a) to participate in the preparation and filing of each such registration
statement, each prospectus included therein or filed with the SEC, and each
amendment thereof or supplement thereto; (b) to receive the documents specified
in Section 1.4 and the notice specified in Section 1.4, and to make the requests
specified in Section 1.4; and (c) to retain counsel to assist Nokia in such
participation. If any such registration statement refers to Nokia by name or
otherwise as the holder of any securities of the Company, then Nokia shall have
the right (in addition to any other rights it may have under this Section 1.8)
to require, in the event that such reference to Nokia by name or otherwise is
not, based on an opinion of legal counsel, required by the Securities Act or any
rules and regulations promulgated thereunder, the deletion of the reference to
Nokia.

               1.9  Indemnification. In the event any Registrable Securities are
                    ---------------
included in a registration statement under this Section 1:

                    (a)  The Company will indemnify and hold harmless Nokia, the
officers, directors and stockholders of Nokia, legal counsel and accountants for
Nokia, any underwriter (as defined in the Act) for Nokia and each person, if
any, who controls Nokia or such underwriter within the meaning of the Act or the
1934 Act, against any losses, claims, damages or liabilities (joint or several)
to which they may become subject under the Act, the 1934 Act or any state
securities laws, 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

                                       7
<PAGE>

violation by the Company of the Act, the 1934 Act, any state securities laws or
any rule or regulation promulgated under the Act, the 1934 Act or any state
securities laws; and the Company will reimburse Nokia, and each such underwriter
or controlling person for any legal or other expenses reasonably incurred by
them in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the indemnity agreement contained
in this subsection 1.9(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 that occurs in reliance upon and in conformity with
written information furnished expressly for use in connection with such
registration by Nokia, any underwriter or any controlling person; provided
further, however, that the foregoing indemnity agreement with respect to any
preliminary prospectus shall not inure to the benefit of Nokia or any
underwriter, or any person controlling Nokia or any underwriter, from whom the
person asserting any such losses, claims, damages or liabilities purchased
shares in the offering, if a copy of the prospectus (as then amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto) was not sent or given by or on behalf of Nokia or underwriter to such
person, if required by law so to have been delivered, at or prior to the written
confirmation of the sale of the shares to such person, and if the prospectus (as
so amended or supplemented) would have cured the defect giving rise to such
loss, claim, damage or liability.

                         (b)  Nokia 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, legal counsel and accountants for the Company,
any underwriter, any other holder selling securities in such registration
statement and any controlling person of any such underwriter or other holder,
against any losses, claims, damages or liabilities (joint or several) to which
any of the foregoing persons may become subject, under the Act, the 1934 Act or
any state securities laws, insofar as such losses, claims, damages or
liabilities (or actions in respect thereto) arise out of or 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 Nokia expressly for use in the preparation of such registration
statement, preliminary or final prospectus, amendment or supplement; and to
reimburse any person intended to be indemnified pursuant to this subsection
1.8(b), for any legal or other expenses reasonably incurred by such person in
connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the indemnity agreement contained
in this subsection 1.8(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 Nokia (which consent shall not be unreasonably withheld),
provided that in no event shall any indemnity under this subsection 1.8(b)
exceed the gross proceeds from the offering received by Nokia.

                         (c)  Promptly after receipt by an indemnified party
under this Section 1.9 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 1.9,
deliver to the indemnifying party a written notice of the

                                       8
<PAGE>

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 counsel mutually satisfactory to the parties; provided, however,
that an indemnified party (together with all other indemnified parties that 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, if prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 1.9, but the omission so to 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 1.9.

                    (d)    If the indemnification provided for in this Section
1.9 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 or alleged omission to state a material fact relates to information
supplied by the indemnifying party or by the indemnified party and the parties'
relative intent, 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 an 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 Nokia under this
Section 1.9 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section 1, and otherwise.

          1.10      Reports Under Securities Exchange Act of 1934.  With a view
                    ---------------------------------------------
to making available to Nokia the benefits of Rule 144 promulgated under the Act
and any other rule or regulation of the SEC that may at any time permit Nokia 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 SEC Rule 144;

                                       9
<PAGE>

                    (b)    file with the SEC in a timely manner all reports and
other documents required of the Company under the Act and the 1934 Act; and

                    (c)    furnish to Nokia, so long as Nokia owns any
Registrable Securities, forthwith upon request (i) a written statement by the
Company that it has complied with the reporting requirements of SEC Rule 144,
the Act and the 1934 Act, 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 Nokia of any rule or regulation of
the SEC that permits the selling of any such securities without registration or
pursuant to such form.

          1.11      Assignment of Registration Rights.  The rights to cause the
                    ---------------------------------
Company to register Registrable Securities pursuant to this Section 1 may be
assigned (but only with all related obligations) by Nokia to a transferee or
assignee of such securities that is a subsidiary, parent, or affiliate, of
Nokia, provided: (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 1.12 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 Act.

          1.12      "Market Stand-Off" Agreement.  Nokia hereby agrees that
                     ---------------------------
during the 90 day period following the effective date of each registration
statement of the Company filed under the Act in connection with any public
offering, it shall not (i) lend, offer, pledge, sell, contract to sell, sell any
option or contract to purchase, purchase any option or contract to sell, grant
any option, right or warrant to purchase, or otherwise transfer or dispose of,
directly or indirectly, any shares of Common Stock or any securities convertible
into or exercisable or exchangeable for Common Stock (whether such shares or any
such securities are then owned by Nokia or are thereafter acquired), or (ii)
enter into any swap or other arrangement that transfers to another, in whole or
in part, any of the economic consequences of ownership of the Common Stock,
whether any such transaction described in clause (i) or (ii) above is to be
settled by delivery of Common Stock or such other securities, in cash or
otherwise, at any time during such period except to the extent Nokia
participates as a selling stockholder in such registrations and except to any
carve-outs set forth in the underwriting documents.  To enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to the
Registrable Securities of Nokia (and the shares or securities of every other
person subject to the foregoing restriction) until the end of such period. Nokia
agrees to execute the form of such market stand-off agreement as may be
reasonably requested by the underwriters.

          1.13      Termination of Registration Rights.  Nokia shall not be
                    ----------------------------------
entitled to exercise any right provided for in this Section 1 at such time at
which all Registrable Securities held by Nokia (and any affiliate of Nokia with
whom Nokia must aggregate its sales under Rule 144) can be sold in any three
(3)-month period without registration in compliance with Rule 144 of the Act.

          2.   Covenants of the Company.
               ------------------------

               2.1  Right to Maintain Percentage Ownership.  Subject to the
                    --------------------------------------
terms and conditions specified in this Section 2.1 and compliance with all
applicable U.S. federal and state securities laws and the rules and regulations
promulgated thereunder, the rules and regulations promulgated by the National
Association of Securities Dealers, Inc. and other such self-regulating or quasi-
public regulatory organizations, including the SEC, the Company hereby grants to
Nokia the right to maintain its percentage ownership of the Company following
future issuances and sales by the Company of any shares of capital stock
("Additional Capital Stock"). For purposes of this Section 2.1, Nokia includes
affiliates of Nokia ("Affiliates"). Nokia shall be entitled to apportion the
right of first offer hereby granted it among itself and Affiliates in such
proportions as it deems appropriate.

          Each time the Company issues and sells Additional Capital Stock, the
Company shall issue and sell shares of its Common Stock to Nokia in accordance
with the following provisions.

                    (a)  The Company shall deliver to Nokia a notice in
accordance with Section 3.9 ("Notice") stating the number of shares of
Additional Capital Stock issued and sold or proposed to be issued and sold, and
the proposed price and date of such sale.

                    (b)  By written notification received by the Company within
(i) thirty (30) calendar days after receipt of the Notice, or (ii) if the sale
of Additional Capital Stock is pursuant to a public offering, fourteen (14)
calendar days after receipt of the Notice, Nokia may elect to purchase or obtain
up to a number of shares of Common Stock that equals the shares of Additional
Capital Stock issued by the Company multiplied by the proportion that the number
of shares of Common Stock issued and held by Nokia immediately prior to the
issuance and sale of Additional Capital Stock bears to the total number of
shares of Common Stock of the Company outstanding immediately prior to the
issuance and sale of the Additional Capital Stock (the "Additional Shares"). In
the event that the sale of Additional Capital Stock is pursuant to a public
offering, any election hereunder shall be irrevocable and the sale of Additional
Shares in connection therewith shall occur in a separate transaction exempt from
the registration requirements of the Securities Act. Without prejudice to the
other provisions of this agreement, Nokia shall not have the right under this
Section 2.1 to purchase any shares of Common Stock that would result in Nokia
holding five percent (5%) or more of the total number of shares of Common Stock
of the Company outstanding.

                    (c)  The rights in this Section 2.1 shall not be applicable
to (i) the issuance or sale of shares of Common Stock (or options therefor) to
employees, directors and consultants for the primary purpose of soliciting or
retaining their services or pursuant to any employee stock option or purchase
plan, or other employee benefit plan, (ii) any dividends or securities issued
pursuant to a stockholder rights plan or other anti-takeover plan adopted by the
Company; (iii) the issuance of Common Stock pursuant to the conversion of
Preferred Stock of the Company (provided, however, that the issuance of the
Preferred Stock shall be subject to the rights in this Section 2.1) (iv) the
issuance of warrants, convertible debt securities, or other convertible or
exercisable securities other than shares of Preferred Stock (provided, however,

                                       11
<PAGE>

that the issuance, upon the exercise or conversion of such securities, of
Additional Capital Stock underlying such securities shall be subject to the
rights in this Section 2.1); (v) the issuance of securities in connection with a
bona fide business acquisition of or by the Company, whether by merger,
consolidation, sale of assets, sale or exchange of stock or otherwise; and (vi)
the issuance of securities pursuant to Section 3.4 of this Agreement.

                    (d)    Subject to the provisions of subsection 2.1(c) above,
the Company shall effect the sale of Additional Shares to Nokia: (i) in the
event of a public offering of Additional Capital Stock or of an other offering
of Additional Capital Stock where the sole consideration payable by the
purchaser is cash (and there are no contemporaneous or related business
relationship between the Company and the purchaser) , at the same price per
share as such Additional Capital Stock, or (ii) in the event of any other
offering of Additional Capital Stock, at the closing sale price per share of
shares of the Company's Common Stock on the date of sale of such Additional
Capital Stock,

                    (e)    The covenant set forth in this Section 2.1 shall
terminate and be of no further force or effect upon the earlier of (i) eighteen
(18) months from the date hereof, (ii) such time that Nokia sells any of the
shares of the Company's Common Stock purchased pursuant to the Purchase
Agreement, or (iii) a Change in Control (as hereinafter defined).

               2.2  Board Representation. The Company shall cause the Company's
                    --------------------
Board of Directors (i) to elect a representative of Nokia that is reasonably
acceptable to the Company (the "Representative") to the Board of Directors and
(ii) nominate and recommend the Representative to the stockholders of the
Company for election to the Board of Directors solely at the next Annual Meeting
of Stockholders of the Company; provided, however, that after 180 days from the
date hereof and upon request of the Company, Nokia covenants and agrees that it
will effect the resignation of the Representative from the Board of Directors.
Notwithstanding the foregoing, if and in the event of a reorganization of the
Company within such 180 day period involving a division of the Company's
technology assets from certain other assets and functions to be held by two
corporations (which may be affiliates of the Company), the Company shall use all
reasonable efforts to cause the Representative to be elected to the Board of
Directors of the corporation which holds the technology assets for an additional
180 day  period; provided, that the Representative resigns from the Board of
Directors of the Company.

               2.3  Observer and Information Rights.  In the event that a
                    -------------------------------
representative of Nokia is not elected to the Board of Directors pursuant to
Section 2.2, for a period equal to the earlier of 180 days from the date hereof
and a Change in Control (as hereinafter defined), the Company shall invite a
representative of Nokia to attend all meetings of its Board of Directors in a
nonvoting observer capacity and, in this respect, shall give such representative
copies of all notices, minutes, consents, management reports and other materials
that it provides to its directors; provided, however, that such representative
shall agree to hold in confidence and trust and to act in a fiduciary manner
with respect to all information so provided; and, provided further, that the
Company reserves the right to withhold any information and to exclude such
representative from any meeting or portion thereof if access to such information
or attendance at such meeting could adversely affect the attorney-client
privilege between the

                                       12
<PAGE>

Company and its counsel, or pose a material conflict of interest (including, but
not limited to, disclosure of confidential or proprietary information relating
to a direct competitor of Nokia).

          3.   Miscellaneous.
               -------------

               3.1  Pooling of Interests Obligation.  In the event of a proposed
                    -------------------------------
acquisition of the Company by another entity by means of any transaction or
series of related transactions (including, without limitation, any
reorganization, merger or consolidation) that results in the transfer of fifty
percent (50%) or more of the outstanding voting power of the Company or a sale
of all or substantially all of the assets of the Company (a "Change in Control")
that requires, as a condition to closing, that the transaction shall be treated
as a pooling of interests under generally accepted accounting principles, Nokia
shall refrain and shall cause its parent company, Nokia Corporation, and any
party controlled by Nokia Corporation (collectively, "Affiliates") to refrain
from taking any action that would prevent a Change in Control of the Company
from being accounted for under the pooling of interests accounting method or
that would prevent the Change in Control from constituting a transaction
qualifying under Section 368(a) of the Code, including but not limited to, (i)
exercising any right of appraisal and (ii) selling or otherwise reducing its
risk relative to any securities received in such combination before such time as
financial results covering at least 30 days of post-transaction combined
operations have been published.

               3.2  Standstill.  For a period of one (1) year from the date
                    ----------
hereof, Nokia, covenants and agrees that it will not, and Nokia will ensure that
the Affiliates will not, without the prior written consent of the Company,
directly or indirectly acquire or agree, offer, seek or propose to acquire,
cause to be acquired or commence any tender or exchange offer seeking to acquire
beneficial ownership of any additional shares of the Company's capital stock so
as to increase its percentage ownership of the Company's capital stock. This
Section 3.2 shall not prevent Nokia from the exercise of its rights pursuant to
Sections 3.4.

               3.3  Prohibition on Resale.  Until the earlier of (i) nine (9)
                    ---------------------
months from the date hereof or (ii) a Change in Control, Nokia covenants and
agrees that it shall not and will ensure that the Affiliates shall not, without
the prior written consent of the Company, (i) lend, offer, pledge, sell,
contract to sell, sell any option or contract to purchase, purchase any option
or contract to sell, grant any option, right or warrant to purchase, or
otherwise transfer or dispose of, directly or indirectly, any shares of Common
Stock acquired pursuant to the Purchase Agreement, or (ii) enter into any swap
or other arrangement that transfers to another, in whole or in part, any of the
economic consequences of ownership of the Common Stock acquired pursuant to the
Purchase Agreement, whether any such transaction described in clause (i) or (ii)
above is to be settled by delivery of Common Stock acquired pursuant to the
Purchase Agreement or such other securities, in cash or otherwise.

               3.4  Subsequent Financing Participation. Subject to the terms and
                    ----------------------------------
conditions specified in this Section 3.4 and compliance with all applicable U.S.
federal and state securities laws and the rules and regulations promulgated
thereunder, the rules and regulations promulgated by the National Association of
Securities Dealers, Inc. and other such self-regulating or quasi-public
regulatory organizations, including the SEC, the Company hereby

                                       13
<PAGE>

grants to Nokia a participation right with respect to the sale by the Company of
Additional Capital Stock to Qualified Investors (as hereinafter defined). In the
event within twelve (12) months from the date hereof, Nokia and the Company have
mutually identified, negotiated with, and the Company has sold Additional
Capital Stock to two or more companies generally recognized as industry-leading
technology providers mutually approved by Nokia and the Company (each, a
"Qualified Investor") in a transaction or series of related transactions not
involving a public offering pursuant to which the Qualified Investors purchase a
percentage of the capital stock of the Company that the Company and Nokia
mutually agree as significant, the Company shall concurrently make an offering
of Additional Shares to Nokia in accordance with the following provisions:

                    (a)  The Company shall deliver a notice in accordance with
Section 3.9 ("Notice") to Nokia stating (i) its bona fide intention to offer
such shares of Additional Capital Stock, (ii) the number of such shares of
Additional Capital Stock to be offered, and (iii) the price and terms upon which
it proposes to offer such shares of Additional Capital Stock.

                    (b)  By written notification received by the Company prior
to the sale of the shares of Additional Capital Stock to the Qualified Investors
which shall in no event be less than 30 days from the date the Company delivers
its notice to Nokia, Nokia may elect to purchase or obtain, at the price and on
the terms specified in the Notice, up to that number of shares of the Company's
Common Stock that equals an additional five percent (5%) of the total number of
shares of Common Stock of the Company outstanding immediately after the sale of
the shares to Nokia and the Qualified Investors.

Nothing contained herein shall obligate the Company to undertake or consummate
any sale of shares of Additional Capital Stock or other securities to any
Qualified Investor.

                    (c)  The rights set forth in this Section 3.4 shall
terminate upon a Change in Control.

               3.5  Successors and Assigns.  Except as otherwise provided
