Exhibit 10.30

December 20, 2002

Mr. Charles Cotton
GlobespanVirata, Inc.
Unit 230 Science Park, Milton Road
Cambridge CB40WB

Dear Charles:

         This letter will express our mutual understanding and agreement
regarding your termination of employment with GlobespanVirata, Inc., a Delaware
corporation, and its subsidiaries and affiliates (all of such entities,
collectively, the "Company").

          By mutual agreement with the Company, your employment with the Company
has been extended to December 20, 2002 (the "Termination Date") when your
employment will expire by effluxion of time and you will cease to be Executive
Chairman of the Company. As at that date you will resign from all other
positions that you may hold or have held as an officer and director of the
Company (including any predecessors thereof). For the avoidance of doubt you
will not be elected or have any contractual entitlement to serve as its
Non-Executive Chairman. You agree to sign and deliver to the Company such other
documents as may be necessary to effect or reflect such resignations which
documentation the Company will prepare at its own cost. You and the Company
agree and acknowledge that the Employment Agreement dated as of October 1, 2001
(the "Employment Agreement") and all other agreements with respect to your
employment or termination thereof, (save as provided for in this compromise
agreement), will be terminated and deemed of no further force or effect, from
and after the Termination Date. The Company and you agree that for a period of
one year from the Termination Date, you will remain available to provide
information, cooperate and consult with the Company on business, legal or other
matters from time to time at the Company's reasonable request ("Consulting
Services"), in partial consideration for the benefits to be received by you,
described below. The amount of time that you will be expected to devote to such
Consulting Services shall be limited to eight hours per calendar quarter and you
will not be required to leave the UK. You will also cooperate with the Company
in providing information with respect to all reports required to be filed with
the Company with the Securities and Exchange Commission as they relate to
required information with respect to you. In this regard, the relationship
between us shall be as independent contractors and you shall be entitled to no
benefits or other consideration normally afforded to employees of the Company
during the time when you perform Consulting Services. You understand and agree
that you will not be entitled to any compensation or benefits from the Company
except as provided in this letter. Not withstanding the extension of your
employment referenced above, you also understand and agree that you shall not be
entitled to any compensation under your employment agreement or otherwise
subsequent to your last day of active employment with the Company on December
14, 2002.

          In consideration of your execution of the release set forth herein and
your agreement to abide by the commitments described in this letter, and in lieu
of and in satisfaction of any agreement or any severance or other payments due
under any severance or other benefit plans maintained by the Company (including
any predecessors thereof), the Employment Agreement or any other individual
agreement previously entered into with you by any Group Company, the Company
will pay or provide to you, commencing no later than the tenth business day
following your delivery of an executed copy of this agreement to the Company,
with the following pay and benefits, which you hereby acknowledge and agree are
in excess of that to which you would be otherwise entitled:

          o     The Company will pay you the balance of the bonus due to
          you in respect of the current year in the sum of US$182,000 (or
          sterling equivalent), payable in a lump sum

<PAGE>

          together with the sum of (pound)80,000 by way of compensation for loss
          of employment and office. The Company will pay (pound)30,000 of this
          amount tax free subject always to the indemnity referred to below and
          will deduct basic rate tax from the balance leaving you to account for
          any higher rate tax to the Inland Revenue.

          o     For a period of 12 months from the Termination Date,
          continuation of the employee benefits (other than any equity program,
          equity-based compensation, incentive or bonus compensation or vacation
          benefits, none of which will continue to accrue or be payable) that
          you are receiving immediately prior to the Termination Date, or, at
          the Company's sole option, a cash payment or payments in lieu of any
          or all of such benefits equal to the cash equivalent of the Company
          contribution that you would have earned from the Company during such
          period under such employee benefit plan or plans had you in fact
          continued to participate in such plans through the end of the 12 month
          period.

          o     The Company will issue you an option to purchase 150,000
          shares of GlobespanVirata common stock at an exercise price of $4.70
          per share.

          o     Each outstanding option to purchase the Company's common
          stock held by you on the Termination Date (including the award of
          150,000 Company stock options described above) shall become fully
          vested and exercisable on the Termination Date.

          o     You will have a period of three years after the Termination
          Date to exercise any and all of your Company stock options
          (including the award of 150,000 Company stock options described
          above). In the event that you do not exercise any or all of your stock
          options during such three-year period, all stock options will
          terminate unexercised upon the expiration of such period.

          o     The Company will reimburse you for any unreimbursed
          reasonable business expenses incurred by you prior to the Termination
          Date (and, with respect to the Consulting Services, after the
          Termination Date), pursuant to the Company's reimbursement policies,
          provided that you present all expense reports to the Company in
          accordance with such policies.

          o     Subject to production of a valid invoice, the Company will
          pay to your legal advisers a maximum of (pound)5,000 plus VAT towards
          the legal fees (including disbursements) which you have incurred in
          connection with the review of this letter and termination of your
          employment.

         You accept the terms set out in this letter in full and final
settlement of all claims you have or may have against the Company and each other
Group Company, and you agree to waive irrevocably and release the Company and
each other Group Company (and all of its or their officers, shareholders or
employees) from any such claims (whether such claims are contractual, statutory
or otherwise and whether present or contingent), arising out of or in connection
with your employment, the termination of your employment or otherwise. The
foregoing waiver and release shall not apply to claims for accrued pension or
personal injuries. You represent that you are not aware of any facts or matters
which might give rise to any such claims. "Group Company" shall mean any of (i)
the Company (ii) any holding company of the Company from time to time and (iii)
any subsidiary of the Company or of any such holding company from time to time.
Holding company and subsidiary shall have the meanings ascribed to them by
Section 736 Companies Act 1985, as amended.

You confirm:
                                                                          2
<PAGE>

          (i)       that you have taken legal advice from a relevant independent
                    adviser (as defined by Section 203 Employment Rights Act
                    1996) as to the terms of this letter and its effect on your
                    ability to pursue your rights before an employment tribunal;
          (ii)      you are aware of your rights under the Employment Rights Act
                    1996, the Disability Discrimination Act 1995, the Race
                    Relations Act 1976, and the Sex Discrimination Act 1975; and
          (iii)     that this agreement relates to all claims you may have
                    against the Company, including but not limited to, any claim
                    for breach of contract, statutory redundancy payment, unfair
                    dismissal, sex, race, or any other discrimination claim, or
                    any claim for unauthorised deduction from wages.

         You and your independent adviser will sign the attached certificate
confirming that the conditions regulating compromise agreements under Section
203 of the Employment Rights Act 1996, Sex Discrimination Act 1975, the Race
Relations Act 1976 and the Disability Discrimination Act 1995 have been
satisfied.

         You agree to return to the Company as of the Termination Date all
Company Property and Information (as defined below). You affirm your obligation
to keep all Company Property and Information confidential and not to use or
disclose it to any third party in the future. The term "Company Property and
Information" means: (i) all property belonging to the Company, including but not
limited to automobiles, cellular phones, other communication devices, and other
property including client lists, files, software, hardware, records, computer
access codes and instruction manuals which you have in your possession, and you
agree not to keep any copies of Company Property and Information, (ii)
confidential information relating to any Group Company, including information
received from third parties under confidential conditions, and (iii) other
technical, marketing, business or financial information, or information relating
to personnel or former personnel of the Group Companies, the use or disclosure
of which might reasonably be construed to be contrary to the interest of the
Company. Similarly, you agree to treat all Information provided to you during
your ongoing Consulting Services as confidential information of the Company in
accordance with the provisions of Section 7 of the Employment Agreement.
Notwithstanding the foregoing, it is agreed you will be entitled to retain your
current laptop computer, docking station, LCD screen and HP Printer at no cost.
You agree to remove all GlobespanVirata confidential information and files from
your computer and to deliver all backups thereof to the Company. You may however
retain the Microsoft Office software currently loaded on the above mentioned
laptop computer.

         You agree that in consideration of the payment of (pound)20,000, the
provisions of Section 10 of the Employment Agreement relating to non-competition
and solicitation shall be replaced by the following, which will remain in full
force and effect for a period of 12 months following the Termination Date (the
"Restricted Period"):

                (a)     you will not, directly or indirectly and whether for
          yourself or on behalf of any other person or organisation, induce or
          attempt to induce so as to leave employment any employee engaged at a
          manager level or above by the Company or any Group Company at the
          Termination Date and with whom you have had dealings or contact in the
          course of your employment at any time within the past 12 months;

                (b)     you will not directly or indirectly and whether for
          yourself or on behalf of any other person or organisation, solicit or
          attempt to entice away from the Company or any Group Company (so as to
          compete with the Company or, as the case may be, any Group Company)
          the business of any person or organisation that has at any time within
          the past 12 months been a customer or supplier or licensee of the
          Company or any Group Company and with whom you or

                                                                          3
<PAGE>
          any of your direct reports have had dealings or contact in the course
          of employment during that time;

                (c)     you will not directly or indirectly and whether for
          yourself or on behalf of any other person or organisation, have
          business dealings with (so as to compete with the Company or, as the
          case may be, any Group Company) any person or organisation that has at
          any time within the past 12 months been a customer or supplier or
          licensee of the Company or any Group Company and with whom you or any
          of your direct reports have had dealings or contact in the course of
          employment during that time;

                (d)     you will not directly or indirectly own, manage,
          control, participate in, consult with, render services for, or in any
          manner engage in any business competing with the businesses of the
          Company or any Group Company in any country where the Company or any
          Group Company currently conducts business.

         Except where obliged to do so to comply with any legal or regulatory
requirement, you agree that you will not make any derogatory or disparaging
comments about the Company, any other Group Company, or any of its or their
officers, shareholders or employees and the Company will use reasonable efforts
to ensure that its officers or employees will not make any derogatory or
disparaging comments about you. The Company agrees to adhere to the wording of
the termination announcement attached to this letter at Schedule 1 in all
material respects and to respond to queries from third parties and prospective
employers in accordance with the spirit and tenor of the termination
announcement.

         You acknowledge and agree that because of the nature of the business in
which the Group Companies are engaged and because of the nature of the Company
Property and Information to which you has had access during your employment, it
would be impractical and excessively difficult to determine the actual damages
of the Group Companies in the event you breached any of the restrictive
covenants contained herein, and remedies at law (such as monetary damages) for
any breach of your covenants would be inadequate. You therefore agree and
consent that if you commit any such breach or threaten to commit any such
breach, the Company will have the right (in addition to, and not in lieu of, any
other right or remedy that may be available to it) to temporary and permanent
injunctive relief from a court of competent jurisdiction, without posting any
bond or other security and without the necessity of proof of actual damage.

          All payments or other benefits made or provided to you under this
letter will be reduced by all income, employment or other taxes required to be
withheld on such payments and other benefits. Except insofar as a deduction in
respect of the same is made by the Company, you accept that you will be
responsible for the payment of any income tax (including, without limitation,
any interest, penalties or fines in connection therewith, (save where interest
or penalties are imposed on the Company in relation to tax it is agreed the
Company should deduct from the sums due to you under this Agreement before
payment to you, but which the Company has delayed remitting to the relevant tax
authority)) imposed by any competent taxation authority by reason of your
receipt of or entitlement to the payment and benefits referred to in this letter
and you agree to indemnify the Company and any Group Company on a continuing
basis against any income tax (including interest, penalties or fines, save as
set out above) imposed by any competent taxation authority by reason of your
receipt of or entitlement to any such payment or benefits.

         You acknowledge that this letter does not and shall not be deemed to
constitute an admission by the Company that it has breached or violated any law
or regulation, or that you have any claims against the Company or that any such
claims have been made by you. The interpretation and enforcement of this letter
will be governed by the laws of England and Wales.

                                                                          4

          On behalf of GlobespanVirata, we thank you for your service to the
Company and wish you every success in your future endeavors. If you agree with
the terms of this letter (together with the certificate, which forms part of
this letter), please countersign both and return them to me.

                                                           Sincerely,

                                                           /s/ Robert McMullan
