SECTION I.        AMENDMENTS TO CREDIT AGREEMENT

                  A. AMENDMENTS TO SECTION 1: DEFINITIONS.

         Foreign Subsidiary of Parent to an Eligible Bank (i) which Indebtedness
         is guaranteed by another Foreign Subsidiary of Parent (a "BACK-TO-BACK

         secured solely by funds in a certificate of deposit or other

<PAGE>

         cash collateral account held by such Eligible Bank to which the
         Indebtedness is owed (a "CD ACCOUNT"), (iii) where all or a portion of
         the funds used by such Back-to-Back Guarantor to fund such CD Account
         are directly or indirectly from the proceeds of a capital contribution
         permitted by Section 6.5 and (iv) at all times the principal amount of
         such Indebtedness shall be equal to or less than the amounts in the CD
         Account."

                  " 'CD ACCOUNT' is defined in the definition of Back-to-Back
         Loans."

                  " 'ELIGIBLE BANK' means (i) a commercial bank or its
         affiliates organized under the laws of the United States, or any state
         thereof or the District of Columbia that (a) is at least "adequately

         regulations) of not less than $100,000,000; (ii) a commercial bank or
         its affiliates organized under the laws of any other country that (a)
         accepts deposits and makes loans in the ordinary course of its

         British Virgin Islands or any other country with similar tax laws, (c)

         acting through a branch or agency located in the country in which it is

         member of the OECD; or (iii) if in any particular country there is no
         commercial bank that qualifies under (i) or (ii) above, then a
         commercial bank organized under the laws of such country that (a)
         accepts deposits and makes loans in the ordinary course of its
         business, (b) has affiliates in the Cayman Islands, Jersey Islands,
         British Virgin Islands or any other country with similar tax laws, and
         (c) has total assets in an amount which ranks such commercial bank in
         terms of total assets in the top one-third of all commercial banks in
         such country which both accept deposits and make loans in the ordinary
         course of their business and have affiliates in the Cayman Islands,
         Jersey Islands, British Virgin Islands or any other country with
         similar tax laws."

                  (b) Section 1.1 of the Credit Agreement is hereby further
amended by deleting the definition of "Fiscal Year" in its entirety and

         January 31 of each following calendar year and (b) with respect to any
         Foreign Subsidiary that is not permitted by applicable laws, rules or
         regulations, or orders of any Governmental Authority, to have a fiscal
         year-end on the Saturday which is the closest to January 31, the annual
         accounting period for such Foreign Subsidiary as of (i) the Closing
         Date or (ii) if such Foreign Subsidiary becomes a Subsidiary of Parent
         after the Closing Date, the date established when such Foreign
         Subsidiary became a Subsidiary of Parent."

                  (c) Section 1.1 of the Credit Agreement is hereby further
amended by deleting the definition of "Fixed Charge Coverage Ratio" in its
entirety and substituting therefore the following:

         four-Fiscal Quarter Period then ending, to (ii) the sum of (A)
         Consolidated Fixed Charges plus (B) the aggregate amount of all
         purchases, redemptions or other acquisitions by Parent of shares of its
         Capital Stock in accordance with Section 6.4(vi), in each case for such
         four-Fiscal Quarter Period."

                  B. AMENDMENTS TO SECTION 3: CONDITIONS PRECEDENT.

         directly owned Foreign Subsidiary in accordance with the terms of
         Section 6.7(i) or Section 6.7(j) and such sale or conveyance results in
         the ownership of such Capital Stock by a Foreign Subsidiary of Parent
         then, (x) the security interest granted to the Administrative Agent in
         such Capital Stock owned by such Foreign Subsidiary shall automatically
         terminate and (y) at the written request and expense of Company,
         Administrative Agent shall take or cause to be taken any action, to
         execute and deliver or cause to be executed and delivered any
         agreement, document and instrument, and make or cause to be made any
         filing and recording, in each case as reasonably requested by Company
         in order to evidence such termination including, without limitation,
         return of the applicable pledged Share Collateral and stock powers
         related thereto. Notwithstanding anything herein to the contrary, 65%
         of the Capital Stock in a Material Foreign Subsidiary which is directly
         owned by Parent or any Domestic Subsidiary of Parent (after giving
         effect to any permitted sale or conveyance in accordance with Section
         6.7(i) and Section 6.7(j)) shall at all times be pledged to
         Administrative Agent as Share Collateral and subject to a First
         Priority Lien in favor of Administrative Agent in accordance with
         Section 5.9(d) and the Pledge Agreement."

                  C. AMENDMENTS TO SECTION 6: NEGATIVE COVENANTS.

                  (a) Section 6.1(g) of the Credit Agreement is hereby amended

         amount not to exceed $50,000,000."

                  (b) Section 6.1(l) of the Credit Agreement is hereby amended

                              OCULAR NETWORKS, INC.

                              AMENDED AND RESTATED
                            2000 STOCK INCENTIVE PLAN

1.   Purpose

     The purpose of this Amended and Restated 2000 Stock Incentive Plan (the
"Plan") of Ocular Networks, Inc., a Delaware corporation (the "Company"), is to
advance the interests of the Company's stockholders by enhancing the Company's
ability to attract, retain and motivate persons who make (or are expected to
make) important contributions to the Company by providing such persons with
equity ownership opportunities and performance-based incentives and thereby
better aligning the interests of such persons with those of the Company's
stockholders. Except where the context otherwise requires, the term "Company"
shall include any of the Company's present or future subsidiary corporations
as defined in Section 424(f) of the Internal Revenue Code of 1986, as amended,
and any regulations promulgated thereunder (the "Code") and any other business
venture (including, without limitation, joint venture or limited liability
company) in which the Company has a significant interest, as determined by the
Board of Directors of the Company (the "Board").

2.   Eligibility

     All of the Company's employees, officers, directors, consultants and
advisors (and any individuals who have accepted an offer for employment) are
eligible to be granted options, restricted stock awards, or other stock-based
awards (each, an "Award") under the Plan. Each person who has been granted an
Award under the Plan shall be deemed a "Participant".

3.   Administration, Delegation

     (a)  Administration by Board of Directors. The Plan will be administered by
the Board. The Board shall have authority to grant Awards and to adopt, amend
and repeal such administrative rules, guidelines and practices relating to the
Plan as it shall deem advisable. The Board may correct any defect, supply any
omission or reconcile any inconsistency in the Plan or any Award in the manner
and to the extent it shall deem expedient to carry the Plan into effect and it
shall be the sole and final judge of such expediency. All decisions by the Board
shall be made in the Board's sole discretion and shall be final and binding on
all persons having or claiming any interest in the Plan or in any Award. No
director or person acting pursuant to the authority delegated by the Board shall
be liable for any action or determination relating to or under the Plan made in
good faith.

     (b)  Delegation to Executive Officers. To the extent permitted by
applicable law, the Board may delegate to one or more executive officers of the
Company the power to make Awards and exercise such other powers under the Plan
as the Board may determine, provided that the Board shall fix the maximum number
of shares subject to Awards and the maximum number of shares for any one
Participant to be made by such executive officers.

                                       1
<PAGE>

     (c)  Appointment of Committees. To the extent permitted by applicable law,
the Board may delegate any or all of its powers under the Plan to one or more
committees or subcommittees of the Board (a "Committee"). All references in the
Plan to the "Board" shall mean the Board or a Committee of the Board or the
executive officer referred to in Section 3(b) to the extent that the Board's
powers or authority under the Plan have been delegated to such Committee or
executive officer.

4.   Stock Available for Awards

     (a)  Number of Shares. Subject to adjustment under Section 8, Awards may be
made under the Plan for up to 8,375,000 shares of common stock, par value $0.001
per share, of the Company (the "Common Stock"). If any Award expires or is
terminated, surrendered or canceled without having been fully exercised or is
forfeited in whole or in part or results in any Common Stock not being issued,
the unused Common Stock covered by such Award shall again be available for the
grant of Awards under the Plan, subject, however, in the case of Incentive Stock
Options (as hereinafter defined), to any limitation required under the Code.
Shares issued under the Plan may consist in whole or in part of authorized but
unissued shares or treasury shares.

     (b)  Per-Participant Limit. Subject to adjustment under Section 8, for
Awards granted after the Common Stock is registered under the Securities
Exchange Act of 1934 (the "Exchange Act"), the maximum number of shares of
Common Stock with respect to which an Award may be granted to any Participant
under the Plan shall be 8,375,000 per calendar year. The per-Participant limit
described in this Section 4(b) shall be construed and applied consistently with
Section 162(m) of the Code.

5.   Stock Options

     (a)  General. The Board may grant options to purchase Common Stock (each,
an "Option") and determine the number of shares of Common Stock to be covered by
each Option, the exercise price of each Option and the conditions and
limitations applicable to the exercise of each Option, including conditions
relating to applicable federal or state securities laws, as it considers
necessary or advisable. An Option which is not intended to be an Incentive Stock
Option (as hereinafter defined) shall be designated a "Nonstatutory Stock
Option".

     (b)  Incentive Stock Options. An Option that the Board intends to be an
"incentive stock option" as defined in Section 422 of the Code (an "Incentive
Stock Option") shall only be granted to employees of the Company and shall be
subject to and shall be construed consistently with the requirements of Section
422 of the Code. The Company shall have no liability to a Participant, or any
other party, if an Option (or any part thereof) which is intended to be an
Incentive Stock Option is not an Incentive Stock Option.

     (c)  Exercise Price. The Board shall establish the exercise price at the
time each Option is granted and specify it in the applicable option agreement.

     (d)  Duration of Options. Each Option shall be exercisable at such times
and subject to such terms and conditions as the Board may specify in the
applicable option agreement.

                                       2
<PAGE>

     (e)  Exercise of Option. Options may be exercised by delivery to the
Company of a written notice of exercise signed by the proper person or by any
other form of notice (including electronic notice) approved by the Board
together with payment in full as specified in Section 5(f) for the number of
shares for which the Option is exercised.

     (f)  Payment Upon Exercise. Common Stock purchased upon the exercise of an
Option granted under the Plan shall be paid for as follows:

          (1)  in cash or by check, payable to the order of the Company;

          (2)  except as the Board may, in its sole discretion, otherwise
provide in an option agreement, by (i) delivery of an irrevocable and
unconditional undertaking by a creditworthy broker to deliver promptly to the
Company sufficient funds to pay the exercise price or (ii) delivery by the
Participant to the Company of a copy of irrevocable and unconditional
instructions to a creditworthy broker to deliver promptly to the Company cash or
a check sufficient to pay the exercise price;

          (3)  when the Common Stock is registered under the Exchange Act, by
delivery of shares of Common Stock owned by the Participant valued at their fair
market value as determined by (or in a manner approved by) the Board in good
faith ("Fair Market Value"), which Common Stock was owned by the Participant at
least six months prior to such delivery;

          (4)  to the extent permitted by the Board, in its sole discretion by
(i) delivery of a promissory note of the Participant to the Company on terms
determined by the Board, or (ii) payment of such other lawful consideration as
the Board may determine; or

          (5)  by any combination of the above permitted forms of payment.

6.   Restricted Stock

     (a)  Grants. The Board may grant Awards entitling recipients to acquire
shares of Common Stock, subject to the right of the Company to repurchase all or
part of such shares at their issue price or other stated or formula price (or to
require forfeiture of such shares if issued at no cost) from the recipient in
the event that conditions specified by the Board in the applicable Award are not
satisfied prior to the end of the applicable restriction period or periods
established by the Board for such Award (each, a "Restricted Stock Award").

     (b)  Terms and Conditions. The Board shall determine the terms and
conditions of any such Restricted Stock Award, including the conditions for
repurchase (or forfeiture) and the issue price, if any. Any stock certificates
issued in respect of a Restricted Stock Award shall be registered in the name of
the Participant and, unless otherwise determined by the Board, deposited by the
Participant, together with a stock power endorsed in blank, with the Company (or
its designee). At the expiration of the applicable restriction periods, the
Company (or such designee) shall deliver the certificates no longer subject to
such restrictions to the Participant or if the Participant has died, to the
beneficiary designated, in a manner determined by the Board, by a Participant to
receive amounts due or exercise rights of the Participant in the event of the
Participant's death (the "Designated Beneficiary"). In the absence of an
effective designation by a Participant, Designated Beneficiary shall mean the
Participant's estate.

                                       3

7.   Other Stock-Based Awards

     The Board shall have the right to grant other Awards based upon the Common
Stock having such terms and conditions as the Board may determine, including the
grant of shares based upon certain conditions, the grant of securities
convertible into Common Stock and the grant of stock appreciation rights.

8.   Adjustments for Changes in Common Stock and Certain Other Events

     (a)  Changes in Capitalization. In the event of any stock split, reverse
stock split, stock dividend, recapitalization, combination of shares,
reclassification of shares, spin-off or other similar change in capitalization
or event, or any distribution to holders of Common Stock other than a normal
cash dividend, (i) the number and class of securities available under this Plan,
(ii) the per-Participant limit set forth in Section 4(b), (iii) the number and
class of securities and exercise price per share subject to each outstanding
Option, (iv) the repurchase price per share subject to each outstanding
Restricted Stock Award, and (v) the terms of each other outstanding Award shall
be appropriately adjusted by the Company (or substituted Awards may be made, if
applicable) to the extent the Board shall determine, in good faith, that such an
adjustment (or substitution) is necessary and appropriate. If this Section 8(a)
applies and Section 8(c) also applies to any event, Section 8(c) shall be
applicable to such event, and this Section 8(a) shall not be applicable.

     (b)  Liquidation or Dissolution. In the event of a proposed liquidation or
dissolution of the Company, the Board shall upon written notice to the
Participants provide that all then unexercised Options will (i) become
exercisable in full as of a specified time at least 10 business days prior to
the effective date of such liquidation or dissolution and (ii) terminate
effective upon such liquidation or dissolution, except to the extent exercised
before such effective date. The Board may specify the effect of a liquidation or
dissolution on any Restricted Stock Award or other Award granted under the Plan
at the time of the grant of such Award.

     (c)  Acquisition Events

          (1)  Definition. An "Acquisition Event" shall mean: (a) any merger or
consolidation of the Company with or into another entity as a result of which
the Common Stock is converted into or exchanged for the right to receive cash,
securities or other property or (b) any exchange of shares of the Company for
cash, securities or other property pursuant to a statutory share exchange
transaction.

          (2)  Consequences of an Acquisition Event on Options. Upon the
occurrence of an Acquisition Event, or the execution by the Company of any
agreement with respect to an Acquisition Event, the Board shall provide that all
outstanding Options shall be assumed, or equivalent options shall be
substituted, by the acquiring or succeeding corporation (or an affiliate
thereof). For purposes hereof, an Option shall be considered to be assumed if,
following consummation of the Acquisition Event, the Option confers the right to
purchase, for each share of Common Stock subject to the Option immediately prior
to the consummation of the Acquisition Event, the consideration (whether cash,
securities or other property) received as a result of the Acquisition Event by
holders of Common Stock for each share of Common Stock

                                       4
<PAGE>

held immediately prior to the consummation of the Acquisition Event (and if
holders were offered a choice of consideration, the type of consideration chosen
by the holders of a majority of the outstanding shares of Common Stock);
provided, however, that if the consideration received as a result of the
Acquisition Event is not solely common stock of the acquiring or succeeding
corporation (or an affiliate thereof), the Company may, with the consent of the
acquiring or succeeding corporation, provide for the consideration to be
received upon the exercise of Options to consist solely of common stock of the
acquiring or succeeding corporation (or an affiliate thereof) equivalent in fair
market value to the per share consideration received by holders of outstanding
shares of Common Stock as a result of the Acquisition Event.

     Notwithstanding the foregoing, if the acquiring or succeeding corporation
(or an affiliate thereof) does not agree to assume, or substitute for, such
Options, then the Board shall, upon written notice to the Participants, provide
that all then unexercised Options will become exercisable in full as of a
specified time prior to the Acquisition Event and will terminate immediately
prior to the consummation of such Acquisition Event, except to the extent
exercised by the Participants before the consummation of such Acquisition Event;
provided, however, that in the event of an Acquisition Event under the terms of
which holders of Common Stock will receive upon consummation thereof a cash
payment for each share of Common Stock surrendered pursuant to such Acquisition
Event (the "Acquisition Price"), then the Board may instead provide that all
outstanding Options shall terminate upon consummation of such Acquisition Event
and that each Participant shall receive, in exchange therefor, a cash payment
equal to the amount (if any) by which (A) the Acquisition Price multiplied by
the number of shares of Common Stock subject to such outstanding Options
(whether or not then exercisable), exceeds (B) the aggregate exercise price of
such Options.

          (3)  Consequences of an Acquisition Event on Restricted Stock Awards.
Upon the occurrence of an Acquisition Event, the repurchase and other rights of
the Company under each outstanding Restricted Stock Award shall inure to the
benefit of the Company's successor and shall apply to the cash, securities or
other property which the Common Stock was converted into or exchanged for
pursuant to such Acquisition Event in the same manner and to the same extent as
they applied to the Common Stock subject to such Restricted Stock Award.

          (4)  Consequences of an Acquisition Event on Other Awards. The Board
shall specify the effect of an Acquisition Event on any other Award granted
under the Plan at the time of the grant of such Award.

9.   General Provisions Applicable to Awards

     (a)  Transferability of Awards. Except as the Board may otherwise determine
or provide in an Award, Awards shall not be sold, assigned, transferred, pledged
or otherwise encumbered by the person to whom they are granted, either
voluntarily or by operation of law, except by will or the laws of descent and
distribution, and, during the life of the Participant, shall be exercisable only
by the Participant. References to a Participant, to the extent relevant in the
context, shall include references to authorized transferees.

     (b)  Documentation. Each Award shall be evidenced by a written instrument
in such form as the Board shall determine. Each Award may contain terms and
conditions in addition to those set forth in the Plan.

     (c)  Board Discretion. Except as otherwise provided by the Plan, each Award
may be made alone or in addition or in relation to any other Award. The terms of
each Award need not be identical, and the Board need not treat Participants
uniformly.

     (d)  Termination of Status. The Board shall determine the effect on an
Award of the disability, death, retirement, authorized leave of absence or other
change in the employment or other status of a Participant and the extent to
which, and the period during which, the Participant, the Participant's legal
representative, conservator, guardian or Designated Beneficiary may exercise
rights under the Award.

     (e)  Withholding. Each Participant shall pay to the Company, or make
provision satisfactory to the Board for payment of, any taxes required by law to
be withheld in connection with Awards to such Participant no later than the date
of the event creating the tax liability. Except as the Board may otherwise
provide in an Award, when the Common Stock is registered under the Exchange Act,
Participants may satisfy such tax obligations in whole or in part by delivery of
shares of Common Stock, including shares retained from the Award creating the
tax obligation, valued at their Fair Market Value. The Company may, to the
extent permitted by law, deduct any such tax obligations from any payment of any
kind otherwise due to a Participant.

     (f)  Amendment of Award. The Board may amend, modify or terminate any
outstanding Award, including but not limited to, substituting therefor another
Award of the same or a different type, changing the date of exercise or
realization, and converting an Incentive Stock Option to a Nonstatutory Stock
Option, provided that the Participant's consent to such action shall be required
unless the Board determines that the action, taking into account any related
action, would not materially and adversely affect the Participant.

     (g)  Conditions on Delivery of Stock. The Company will not be obligated to
deliver any shares of Common Stock pursuant to the Plan or to remove
restrictions from shares previously delivered under the Plan until (i) all
conditions of the Award have been met or removed to the satisfaction of the
Company, (ii) in the opinion of the Company's counsel, all other legal matters
in connection with the issuance and delivery of such shares have been satisfied,
including any applicable securities laws and any applicable stock exchange or
stock market rules and regulations, and (iii) the Participant has executed and
delivered to the Company such representations or agreements as the Company may
consider appropriate to satisfy the requirements of any applicable laws, rules
or regulations.

     (h)  Acceleration. The Board may at any time provide that any Options shall
become immediately exercisable in full or in part, that any Restricted Stock
Awards shall be free of restrictions in full or in part or that any other Awards
may become exercisable in full or in part or free of some or all restrictions or
conditions, or otherwise realizable in full or in part, as the case may be.

10.  Miscellaneous

     (a)  No Right To Employment or Other Status. No person shall have any claim
or right to be granted an Award, and the grant of an Award shall not be
construed as giving a Participant the right to continued employment or any other
relationship with the Company. The Company expressly reserves the right at any
time to dismiss or otherwise terminate its relationship with a Participant free
from any liability or claim under the Plan, except as expressly provided in the
applicable Award.

     (b)  No Rights As Stockholder. Subject to the provisions of the applicable
Award, no Participant or Designated Beneficiary shall have any rights as a
stockholder with respect to any shares of Common Stock to be distributed with
respect to an Award until becoming the record holder of such shares.
Notwithstanding the foregoing, in the event the Company effects a split of the
Common Stock by means of a stock dividend and the exercise price of and the
number of shares subject to such Option are adjusted as of the date of the
distribution of the dividend (rather than as of the record date for such
dividend), then an optionee who exercises an Option between the record date and
the distribution date for such stock dividend shall be entitled to receive, on
the distribution date, the stock dividend with respect to the shares of Common
Stock acquired upon such Option exercise, notwithstanding the fact that such
shares were not outstanding as of the close of business on the record date for
such stock dividend.

     (c)  Effective Date and Term of Plan. The Plan shall become effective on
the date on which it is adopted by the Board. No Awards shall be granted under
the Plan after the completion of ten years from the earlier of (i) the date on
which the Plan was adopted by the Board or (ii) the date the Plan was approved
by the Company's stockholders, but Awards previously granted may extend beyond
that date.

     (d)  Amendment of Plan. The Board may amend, suspend or terminate the Plan
or any portion thereof at any time.

     (e)  Governing Law. The provisions of the Plan and all Awards made
hereunder shall be governed by and interpreted in accordance with the laws of
the State of Delaware, without regard to any applicable conflicts of law.
