Lehman Brothers Inc.

Ladies and Gentlemen:

         Mindspeed Technologies, Inc., a Delaware corporation (the "COMPANY"),
proposes, subject to the terms and conditions stated herein, to issue and sell
$40,000,000 aggregate principal amount of its 3.75% Convertible Senior Notes due
2009 (the "FIRM NOTES") to Lehman Brothers Inc. (the "INITIAL PURCHASER"). In
addition, the Company proposes to grant to the Initial Purchaser an option to
purchase up to an additional $6,000,000 aggregate principal amount of its 3.75%
Convertible Senior Notes due 2009 on the terms set forth in Section 2 (the
"OPTION NOTES" and, together with the Firm Notes, the "NOTES"). This is to
confirm the agreement between the Company and the Initial Purchaser concerning
the offer, issue and sale of the Notes.

         The Notes will be issued pursuant to an indenture (the "INDENTURE") to
be dated as of the First Delivery Date (as defined in Section 2(a)), between the
Company and Wells Fargo Bank, N.A., as Trustee (the "TRUSTEE"). The Notes will
be convertible into duly and validly issued, fully paid and non-assessable
shares of common stock, $0.01 par value per share (the "COMMON STOCK"), of the
Company, together with the rights (the "RIGHTS") evidenced by such Common Stock
to the extent provided in the Rights Agreement dated June 26, 2003 between the
Company and Mellon Investor Services LLC as rights agent, as amended (the
"RIGHTS AGREEMENT"), (such shares of Common Stock into which the Notes are
convertible, the "CONVERSION SHARES") on the terms, and subject to the
conditions, set forth in the Indenture.

         The Notes will be offered and sold to the Initial Purchaser without
being registered under the Securities Act of 1933, as amended, and the rules and
regulations of the Securities and Exchange Commission (the "COMMISSION")
thereunder (collectively, the "SECURITIES ACT"), in reliance upon an exemption
therefrom.

         Holders of the Notes (including the Initial Purchaser and its direct
and indirect transferees) will be entitled to the benefits of a Registration
Rights Agreement, dated as of the First Delivery Date, between the Company and
the Initial Purchaser (the "REGISTRATION RIGHTS AGREEMENT"), the form of which
is contained in Annex A hereof, pursuant to which the Company will agree, among
other things, to file with the Commission a shelf registration

                                                                               2

statement pursuant to Rule 415 under the Securities Act (the "REGISTRATION
STATEMENT") covering the resale of the Notes and the Conversion Shares, and to
use its reasonable best efforts to cause the Registration Statement to be
declared effective within the time periods specified therein.

         Holders of the Notes will be entitled to the benefits of a Pledge
Agreement (the "PLEDGE AGREEMENT"), pursuant to which the Company will deposit
with and pledge to the Trustee for the benefit of the holders of the Notes a
portfolio of securities (the "PLEDGED SECURITIES") consisting of U.S. government
securities in such amount as the Company expects will be sufficient, upon
receipt of scheduled interest payments thereof, to provide for the payment of
the first four scheduled interest payments on the Notes when due. Pursuant to a
Control Agreement (the "CONTROL AGREEMENT"), the Pledged Securities shall be
held in an account maintained with a securities intermediary and depositary
bank.

         This Agreement, the Indenture, the Registration Rights Agreement, the
Pledge Agreement and the Control Agreement are referred to herein collectively
as the "TRANSACTION DOCUMENTS".

                  1. Representations, Warranties and Agreements of the Company.
The Company represents, warrants to and agrees with, the Initial Purchaser that:

                           (a) The Company has prepared a preliminary offering
         memorandum dated December 2, 2004 (the "PRELIMINARY OFFERING
         MEMORANDUM") and will prepare an offering memorandum dated the date
         hereof (the "OFFERING MEMORANDUM") setting forth information concerning
         the Company, the Notes, the Common Stock, the Indenture, the Pledge
         Agreement and the Registration Rights Agreement, in form and substance
         satisfactory to you. Copies of the Preliminary Offering Memorandum have
         been, and copies of the Offering Memorandum will be, delivered by the
         Company to you. As used in this Agreement, "PRELIMINARY OFFERING
         MEMORANDUM" or "OFFERING MEMORANDUM" means the Preliminary Memorandum
         or Offering Memorandum, as the case may be, including the documents
         incorporated by reference therein, as amended or supplemented. Each of
         the Preliminary Offering Memorandum and the Offering Memorandum, will
         not as of its respective date, and the Offering Memorandum will not as
         of the applicable Delivery Date (as defined in Section 2(b)), contain
         any untrue statement of a material fact or omit to state a material
         fact necessary in order to make the statements therein, in the light of
         the circumstances under which they were made, not misleading; provided
         that, the Company makes no representation or warranty as to information
         contained in or omitted from the Preliminary Offering Memorandum or the
         Offering Memorandum in reliance upon and in conformity with the written
         information furnished to the Company by the Initial Purchaser
         specifically for inclusion therein.

                           (b) The documents incorporated by reference in the
         Offering Memorandum (the "INCORPORATED DOCUMENTS"), when they became
         effective or were filed with the Commission, as the case may be,
         conformed in all material respects to the requirements of the
         Securities Exchange Act of 1934, as amended, and the rules and
         regulations of the Commission thereunder (collectively, the "EXCHANGE
         ACT"), as applicable, and none of such documents contained any untrue
         statement of a material fact
<PAGE>
                                                                               3

         or omitted to state any material fact required to be stated therein or
         necessary to make the statements therein, in light of the circumstances
         under which they were made, not misleading; and any further documents
         so filed and incorporated by reference in the Offering Memorandum, when
         such documents are filed with the Commission will conform in all
         material respects to the requirements of the Exchange Act and will not
         contain any untrue statement of a material fact or omit to state any
         material fact required to be stated therein or necessary to make the
         statements therein, in light of the circumstances under which they were
         made, not misleading.

                           (c) The Company has established and maintains
         disclosure controls and procedures (as such term is defined in Rule
         13a-14 under the Exchange Act); (ii) such disclosure controls and
         procedures are designed to ensure that material information relating to
         the Company, including its consolidated subsidiaries, is made known to
         the Company's principal executive officer and its principal financial
         officer by others within those entities, particularly during the
         periods in which the periodic reports required under the Exchange Act
         are being prepared; and (iii) such disclosure controls and procedures
         are effective in all material respects to perform the functions for
         which they were established.

                           (d) The Company's auditors and the audit committee of
         the board of directors have been advised of (i) all significant
         deficiencies and material weaknesses in the design or operation of
         internal control over financial reporting which are reasonably likely
         to adversely affect the Company's ability to record, process, summarize
         and report financial information; and (ii) any fraud, whether or not
         material, that involves management or other employees who have a
         significant role in the Company's internal control over financial
         reporting.

                           (e) Since the date of the most recent evaluation of
         such disclosure controls and procedures, there have been no significant
         changes in internal controls or in other factors that could
         significantly affect internal controls, including any corrective
         actions with regard to significant deficiencies and material
         weaknesses.

                           (f) The Company and each of its subsidiaries with
         active operations (each, a "Subsidiary" and collectively,
         "Subsidiaries") has been duly incorporated or formed, as the case may
         be, and is validly existing as a corporation, foreign corporation or
         limited liability company, as the case may be, in good standing under
         the laws of its jurisdiction of incorporation or formation, as the case
         may be, is duly qualified to do business and is in good standing as a
         foreign corporation or a limited liability company in each jurisdiction
         in which its ownership or lease of property or the conduct of its
         businesses requires such qualification, except where the failure to be
         so qualified could not reasonably be expected to have a material
         adverse effect on the business, financial condition, stockholders'
         equity or results of operations of the Company and its subsidiaries
         taken as a whole (a "MATERIAL ADVERSE EFFECT"), and has all power and
         authority necessary to own, lease or hold its properties and to conduct
         the businesses in which it is engaged.

                                                                               4

                           (g) The Company has an authorized and issued
         capitalization as set forth in the Offering Memorandum, and all of the
         issued shares of capital stock of the Company have been duly and
         validly authorized and issued, are fully paid and non-assessable and
         conform to the description thereof contained in the Offering
         Memorandum; and all of the issued shares of capital stock of each
         subsidiary of the Company have been duly and validly authorized and
         issued and are fully paid and non-assessable and (except for directors'
         qualifying shares), and except as set forth in the Offering Memorandum,
         are owned directly or indirectly by the Company, free and clear of all
         liens, encumbrances, equities, claims or adverse interests
         (collectively, "LIENS") of any nature. There has been no change in the
         authorized or issued capitalization of the Company or any of its
         Subsidiaries since the date indicated in the Offering Memorandum except
         with respect to (i) changes occurring in the ordinary course of
         business and (ii) changes in outstanding Common Stock resulting from
         transactions relating to the Company's employee benefit plans.

                           (h) No relationship, direct or indirect, exists
         between or among the Company, on the one hand, and the directors,
         officers, stockholders, customers or suppliers of the Company, on the
         other hand, which would be required to be set forth in the Offering
         Memorandum if the Offering Memorandum were a prospectus included or
         incorporated by reference in a registration statement on Form S-3 that
         has not been so set forth.

                           (i) Except as set forth in the Offering Memorandum,
         there are no legal or governmental proceedings, actions, suits, claims,
         arbitrations, investigations or proceedings pending or, to the
         Company's knowledge, threatened to which the Company or any of its
         subsidiaries is or could be a party or to which any of their respective
         properties is or could be subject that would be required to be
         described in the Offering Memorandum if the Offering Memorandum were a
         prospectus included in a registration statement on Form S-1 and are not
         so described or that could reasonably be expected to have a Material
         Adverse Effect or would materially and adversely affect the ability of
         the Company to perform its obligations under the Transaction Documents;
         nor are there any statutes, regulations, contracts or other documents
         that would be required to be described in the Offering Memorandum if
         the Offering Memorandum were a prospectus included in a registration
         statement on Form S-1, in each case except as are set forth or
         incorporated by reference in the Offering Memorandum; and, to the
         Company's knowledge, no such proceedings are threatened or contemplated
         by governmental authorities or threatened by others.

                           (j) Except with respect to the rights contained in
         the Registration Rights Agreement and except as set forth in the
         Offering Memorandum, there are no contracts, agreements or other
         documents between the Company and any person granting such person the
         right to require the Company to file a registration statement under the
         Securities Act with respect to any securities of the Company owned or
         to be owned, directly or indirectly, by such person or to require the
         Company to include such securities in any registration statement filed
         by the Company.

                           (k) Neither the Company nor any of its Subsidiaries
         (i) is in violation of its charter or by-laws, (ii) is in default, and
         no event has occurred which, with notice or lapse of time or both,
         would constitute such a default, in the due performance or observance
         of any term, covenant or condition contained in any indenture,
         mortgage, deed of trust, loan agreement or other agreement or
         instrument to which it is a party or by which it is bound or to which
         any of its properties or assets is subject or (iii) is in violation of
         any law, ordinance, governmental rule, regulation or court decree to
         which it or its property or assets may be subject or has failed to
         obtain any material license, permit, certificate, franchise or other
         governmental authorization or permit necessary to the ownership of its
         property or to the conduct of its business, except in the case of
         clauses (ii) and (iii) above, for any such default, the occurrence of
         any such event, any violation or the failure to obtain any such
         license, permit, certificate, franchise or authorization that,
         individually or in the aggregate, could not reasonably be expected to
         have a Material Adverse Effect.

                           (l) Neither the Company nor any of its Subsidiaries
         has sustained, since the date of the latest audited financial
         statements included and incorporated by reference in the Offering
         Memorandum, any material loss or interference with its business from
         fire, explosion, flood or other calamity, whether or not covered by
         insurance, or from any labor dispute or court or governmental action,
         order or decree (a "MATERIAL LOSS"); and, since such date, there has
         not been any change in the capital stock, short-term debt or long-term
         debt of the Company or any of its Subsidiaries or any change or
         development involving a prospective change that could reasonably be
         expected to have a Material Adverse Effect.

                           (m) The consolidated financial statements of the
         Company and its subsidiaries (including the related notes and
         supporting schedules) included or incorporated by reference in the
         Preliminary Offering Memorandum and Offering Memorandum present fairly
         in all material respects the financial condition, results of operations
         and changes in financial position of the Company and its subsidiaries
         on the basis stated therein at the respective dates or for the
         respective periods to which they apply; such statements and related
         schedules and notes have been prepared in accordance with generally
         accepted accounting principles consistently applied throughout the
         periods involved, except as disclosed therein; the supporting
         schedules, if any, included or incorporated by reference in the
         Preliminary Offering Memorandum or the Offering Memorandum present
         fairly in all material respects in accordance with generally accepted
         accounting principles the information required to be stated therein;
         and the other financial information and data set forth in the
         Preliminary Offering Memorandum and Offering Memorandum (and any
         amendment or supplement thereto) are, in all material respects,
         accurately presented and prepared on a basis consistent with such
         financial statements (including the related notes and supporting
         schedules) and the books and records of the Company.

                           (n) Deloitte & Touche LLP (the "ACCOUNTANTS"), who
         have audited the financial statements of the Company, whose report is
         incorporated by reference in the Offering Memorandum and who have
         delivered the initial letter referred to in Section 5(f)
<PAGE>
                                                                               6

         hereof, are an independent registered public accounting firm as
         required by the Securities Act; and the Accountants, whose report is
         incorporated by reference in the Offering Memorandum and who have
         delivered one of the initial letters referred to in Section 5(f)
         hereof, were an independent registered public accounting firm as
         required by the Securities Act during the periods covered by the
         financial statements on which they reported.

                           (o) Except as set forth in the Offering Memorandum,
         the Company and each of its subsidiaries have good and marketable title
         in fee simple to all real property and good and marketable title to all
         personal property owned by them, in each case free and clear of all
         liens, encumbrances and defects, except such as do not materially
         affect the value of such property and do not materially interfere with
         the use made and proposed to be made of such property by the Company
         and its subsidiaries; and all assets held under lease by the Company
         and its subsidiaries are held by them under valid, subsisting and
         enforceable leases, with such exceptions as are not material and do not
         interfere with the use made and proposed to be made of such property
         and buildings by the Company and its subsidiaries.

                           (p) The Company and each of its subsidiaries carry,
         or are covered by, insurance in such amounts and covering such risks as
         is adequate for the conduct of their respective businesses and the
         value of their respective properties from insurers of recognized
         financial responsibility and as is customary for companies engaged in
         similar businesses in similar industries. Neither the Company nor any
         of its subsidiaries (i) has received notice from any insurer or agent
         of such insurer that substantial capital improvements or other material
         expenditures will have to be made in order to continue such insurance
         or (ii) has any reason to believe that it will not be able to renew its
         existing insurance coverage as and when such coverage expires or to
         obtain similar coverage from similar insurers at a cost that could not
         reasonably be expected to have a Material Adverse Effect.

                           (q) The Company and each of its subsidiaries has such
         permits, licenses, consents, exemptions, franchises, authorizations and
         other approvals (each, an "AUTHORIZATION") of, and has made all filings
         with and notices to, all governmental or regulatory authorities and
         self-regulatory organizations and all courts and other tribunals,
         including, without limitation, under any applicable environmental law,
         ordinance, rule, regulation, order, judgment, decree or permit, as are
         necessary to own, lease, license and operate its respective properties
         and to conduct its business, except where the failure to have any such
         Authorization or to make any such filing or notice could not reasonably
         be expected to have a Material Adverse Effect; each such Authorization
         is valid and in full force and effect and the Company and each of its
         subsidiaries is in compliance with all the terms and conditions thereof
         and with the rules and regulations of the authorities and governing
         bodies having jurisdiction with respect thereto; and no event has
         occurred (including, without limitation, the receipt of any notice from
         any authority or governing body) which allows or, after notice or lapse
         of time or both, would allow, revocation, suspension or termination of
         any such Authorization or results or, after notice or lapse of time or
         both, would result in any other impairment of the rights of the holder
         of any such
<PAGE>
                                                                               7

         Authorization; and such Authorizations contain no restrictions that are
         burdensome to the Company or any of its subsidiaries, except where such
         failure to be valid and in full force and effect or to be in
         compliance, the occurrence of any such event or the presence of any
         such restriction, individually or in the aggregate, could not
         reasonably be expected to have a Material Adverse Effect.

                           (r) The Company and each of its subsidiaries own or
         possess adequate rights to use all material patents, patent rights,
         patent applications, trademarks, service marks, trade names, trademark
         registrations, service mark registrations, copyrights, inventions,
         know-how (including trade secrets and other unpatented and/or
         unpatentable proprietary of confidential information, systems or
         procedures) and licenses necessary for the conduct of their respective
         businesses and have no reason to believe that the conduct of their
         respective businesses will conflict with, and neither the Company nor
         any of its subsidiaries has received any notice of infringement of or
         conflict with, asserted rights of others with respect to any of such
         intellectual property which, individually or in the aggregate, would
         reasonably be expected to have a Material Adverse Effect.

                           (s) None of the Company and its subsidiaries is
         involved in any strike, job action or labor dispute with any group of
         employees that could reasonably be expected to have a Material Adverse
         Effect, and, to the Company's knowledge, no such action or dispute is
         threatened.

                           (t) The Company and each of its subsidiaries is in
         compliance in all material respects with all presently applicable
         provisions of the Employee Retirement Income Security Act of 1974, as
         amended, and the regulations and published interpretations thereunder
         (collectively, "ERISA"); no "reportable event" (as defined in ERISA)
         has occurred with respect to any "pension plan" (as defined in ERISA)
         for which the Company would have any liability; the Company has not
         incurred and does not expect to incur liability under (i) Title IV of
         ERISA with respect to termination of, or withdrawal from, any "pension
         plan" or (ii) Sections 412 or 4971 of the Internal Revenue Code of

         and each "pension plan" for which the Company would have any liability
         that is intended to be qualified under Section 401(a) of the Internal
         Revenue Code is so qualified in all material respects and nothing has
         occurred, whether by action or by failure to act, which would cause the
         loss of such qualification.

         filed all federal, state and local income and franchise tax returns

         (including withholding taxes, penalties and interest, assessments, fees
         and other charges) due thereon, except where the failure to file or pay
         such taxes could not reasonably be expected to have a Material Adverse
         Effect; and no tax deficiency has been determined adversely to the
         Company or any of its subsidiaries which has had (nor does the Company
         have any knowledge of any tax deficiency which, if determined adversely
         to the Company or any of its subsidiaries, could reasonably be expected
         to have) a Material Adverse Effect.

         only in accordance with management's authorization and (D) the reported
         accountability for its assets is compared with existing assets at

         any differences.

            2. Purchase, Sale and Delivery of Notes.

                           (a) Subject to the terms and conditions and in
         reliance upon the representations and warranties herein set forth, the
         Company agrees to sell to the Initial Purchaser, and the Initial
         Purchaser agrees to purchase from the Company, at a purchase price of

                                                                              14

         agreement between the Initial Purchaser and the Company (such date and
         time of delivery and payment for the Firm Notes being referred to
         herein as the "FIRST DELIVERY DATE"). Delivery of the Firm Notes by the
         Company shall be made to the Initial Purchaser against payment of the
         purchase price by the Initial Purchaser; and payment for the Firm Notes
         by the Initial Purchaser shall be made against delivery to the Initial
         Purchaser of the Firm Notes as set forth below and effected either by
         wire transfer of immediately available funds to an account with a bank
         in The City of New York, the account number and the ABA number for such
         bank to be provided by the Company to the Initial Purchaser at least
         two business days in advance of the First Delivery Date, or by such
         other manner of payment as may be agreed by the Company and the Initial
         Purchaser.

                           Subject to the terms and conditions and in reliance
          upon the representations and warranties herein set forth, the Company
          hereby grants the option to the Initial Purchaser to purchase the
          Option Notes at the same purchase price as the Initial Purchaser will
          pay for the Firm Notes. The option may be exercised in whole or in
          part at any time and from time to time upon notice in writing or by
          facsimile by Lehman Brothers Inc. to the Company setting forth the
          amount (which shall be an integral multiple of $1,000 principal
          amount) of Option Notes as to which such option is being exercised;
          provided that the Option Delivery Date (as defined below) must not be
          more than 30 days subsequent to the date of this Agreement; and
          provided further that Option Notes may not be issued in whole or in
          part after the period which ends 13 days after the date hereof
          (counting the date hereof as the first day) unless the Initial
          Purchaser determines that such Option Notes would not be treated as
          having been issued with "original issue discount" for purposes of
          Sections 1271-1275 of the Internal Revenue Code and the applicable
          Treasury regulations promulgated thereunder.

                           The date for the delivery of and payment for the
          Option Notes, being herein referred to as an "OPTION DELIVERY DATE",
          which may be the First Delivery Date (the First Delivery Date and the
          Option Delivery Date, if any, being referred to as a "DELIVERY DATE"),
          shall be determined by the Initial Purchaser but shall not be later
          than five full business days after written notice of election to
          purchase Option Notes is given. Delivery of the Option Notes by the
          Company shall be made to the Initial Purchaser against payment of the
          purchase price therefor by the Initial Purchaser; and payment for the
          Option Notes by the Initial Purchaser shall be made against delivery
          to the Initial Purchaser of the Option Security as set forth below and
          effected either by wire transfer of immediately available funds to an
          account with a bank in The City of New York, the account number and
          the ABA number for such bank to be provided by the Company to the
          Initial Purchaser at least two business days in advance of the Option
          Delivery Date, or by such other manner of payment as may be agreed by
          the Company and the Initial Purchaser.

                           (b) The Company will deliver against payment of the
         purchase price the Notes initially sold to qualified institutional
         buyers ("QIBS"), as defined in Rule 144A, in the form of one or more
         permanent global certificates (the "GLOBAL NOTES"), registered in the
         name of Cede & Co., as nominee for The Depository Trust Company
<PAGE>
                                                                              15

         ("DTC"). Beneficial interests in the Notes initially sold to QIBs will
         be shown on, and transfers thereof will be effected only through,
         records maintained in book-entry form by DTC and its participants. The
         Global Notes will be made available, at the request of the Initial
         Purchaser, for checking at least 24 hours prior to such Delivery Date.

                           (c) Notwithstanding the foregoing, at each Delivery
         Date, the Company shall irrevocably instruct the Initial Purchaser to
         (i) purchase Pledged Securities on behalf of the Company using a
         portion of the net proceeds from the issuance of the Notes in such
         amount as the Company expects will be sufficient, upon receipt of
         scheduled interest and principal payments thereof, to provide for the
         payment of the first four scheduled interest payments on the Notes when
         due and (ii) deliver such Pledged Securities on behalf of the Company
         to the Trustee, for its benefit and the ratable benefit of the holders
         of the Notes, pursuant to the Pledge Agreement.

                           (d) Time shall be of the essence, and delivery at the
         time and place specified pursuant to this Agreement is a further
         condition of the obligations of the Initial Purchaser hereunder.

            3. Further Agreements of the Company. The Company agrees:

                           (a) To prepare the Offering Memorandum in a form

                           (b) To advise the Initial Purchaser promptly of any
         proposal to amend or supplement the Offering Memorandum and not to
         effect any such amendment or supplement without the consent of the
         Initial Purchaser. If, at any time prior to completion of the resale of
         the Notes by the Initial Purchaser, any event shall occur or condition
         exist as a result of which it is necessary to amend or supplement the
         Offering Memorandum in order that the Offering Memorandum will not
         include an untrue statement of a material fact or omit to state a
         material fact necessary in order to make the statements therein, in the
         light of the circumstances existing at the time it is delivered to a
         purchaser, not misleading, to promptly notify the Initial Purchaser and
         prepare, subject to the first sentence of this Section 3(b), such
         amendment or supplement as may be necessary to correct such untrue
         statement or omission;

                           (c) To furnish promptly to the Initial Purchaser and
         to Simpson Thacher & Bartlett LLP, counsel to the Initial Purchaser,
         copies of the Preliminary Offering Memorandum and the Offering
         Memorandum (and all amendments and supplements thereto), as soon as
         available and in such quantities as the Initial Purchaser reasonably
         requests for internal use and for distribution to prospective
         purchasers; and to furnish to the Initial Purchaser on the date hereof
         four copies of the Offering Memorandum signed by duly authorized
         officers of the Company, one of which will include the independent
         auditors' report therein manually signed by such independent auditors.
         The Company will pay the expenses of printing and distributing to the
         Initial Purchaser all such documents;

                           (d) Promptly from time to time, to take such action
         as the Initial Purchaser may reasonably request, to qualify the Notes
         for offering and sale under the securities laws of such jurisdictions
         as the Initial Purchaser may request and to comply with such laws so as
         to permit the continuance of sales and dealings therein in such
         jurisdictions for as long as may be necessary to complete the resale of
         the Notes; provided that, in connection therewith, the Company shall
         not be required to qualify as a foreign corporation or to file a
         general consent to service of process in any jurisdiction in which the
         Company is not already so qualified or has not so consented;

                           (e) For a period of two years following the First
         Delivery Date, to furnish to the Initial Purchaser upon request copies
         of all materials furnished by the Company to its stockholders and all
         public reports and all reports and financial statements furnished by
         the Company to the principal national securities exchange upon which
         the Notes or Common Stock may be listed pursuant to requirements of or
         agreements with such exchange or to the Commission pursuant to the
         Exchange Act; provided, however, that the Company shall not be required
         to provide the Initial Purchaser with any such reports or similar forms
         that have been filed with the Commission by electronic transmission
         pursuant to EDGAR;

                           (f) For a period of 90 days from the date hereof, not
         to, directly or indirectly, (1) announce an offering of, or file any
         registration statement with the Commission relating to, debt or equity

         to the Company's employee benefit plans) or offer for sale, sell,
         pledge or otherwise dispose of (or enter into any transaction or device
         which is designed to, or could be expected to, result in the
         disposition or purchase by any person at any time in the future of) any
         debt or equity securities of the Company (other than the Notes), any
         securities convertible into or exchangeable for Common Stock or
         substantially similar securities (other than the Notes, the Conversion
         Shares and Common Stock to be issued in the ordinary course under the
         Company's employee benefit plans, qualified stock option plans or other
         employee compensation plans existing on the date hereof or pursuant to
         currently outstanding options, warrants or rights) or sell or grant
         options, warrants or rights with respect to any shares of Common Stock
         or securities convertible into or exchangeable for Common Stock (other
         than the grant of options, warrants or rights pursuant to option or
         other employee compensation plans existing on the date hereof) or (2)
         enter into any swap or other derivatives transaction that transfers to
         another, in whole or in part, any of the economic benefits or risks of
         ownership of such shares of Common Stock, whether any such transaction
         described in clause (1) or (2) above is to be settled by delivery of
         Common Stock or other securities, in cash or otherwise, without the
         prior written consent of the Initial Purchaser; and to cause each
         executive officer and director of the Company to furnish to the Initial
         Purchaser, on or prior to the date hereof, a letter substantially in
         the form of Annex B hereto; provided however, that notwithstanding the
         foregoing, the Company may take any action required to be taken by it
         under those registration rights agreements described in the Offering
         Memorandum;

         which is designed to stabilize or manipulate, or which constitutes or
         which might reasonably be expected to cause or result in stabilization
         or manipulation, of the price of any security of the Company in
         connection with the offering of the Notes;

         under Investment Company Act;

                           (n) For so long as any of the Notes are "restricted

         not to, sell, offer for sale or solicit offers to buy or otherwise
         negotiate in respect of any "security" (as defined in the Securities
         Act) in a transaction that could be integrated with the sale of the

                  opinion is given as to any subsequent resale of the Notes or

                  Control Agreement by the parties thereto operate to perfect

                  In rendering such opinion, such counsel may state that their
         opinion is limited to matters governed by the federal laws of the
         United States of America and the laws of the States of California, New
         York and Delaware. In rendering such opinion, such counsel may rely (A)
         as to matters involving the application of laws of any jurisdiction
         other than the States of California, New York, Delaware or the United
         States, to the extent they deem proper and specified in such opinion,
         upon the opinion of other counsel of good standing whom they believe to
         be reliable and who are reasonably satisfactory to counsel for the
         Initial Purchaser and (B) as to matters of fact, to the extent they
         deem proper, on certificates of responsible officers of the Company and
         public officials. References to the Offering Memorandum in this
         paragraph (c) include any supplements thereto at the Closing Date. Such

         with officers and other representatives of the Company, the Company's
         independent accountants and the Initial Purchaser and their counsel, at
         which the contents of the Offering Memorandum were discussed (although
         such counsel may state that it has not independently verified the
         accuracy, completeness or fairness of such statements except as set
         forth in clauses (x), (xi) and (xv) above), and (y) based on the
         foregoing, no facts have come to the attention of such counsel which
         lead such counsel to believe that the Offering Memorandum (except for
         the financial statements, supporting schedules, footnotes and other
         financial and statistical information included or incorporated by
         reference therein, as to which such counsel need express no belief), as
         of its date or as of the applicable Delivery Date, contained or
         contains any untrue statement of a material fact or omitted or omits to
         state a material fact necessary in order to make the statements
         therein, in light of the circumstances under which they were made, not
         misleading.

                           (d) Morrison & Foerster LLP, counsel to the Company,
         shall have furnished to the Trustee a reliance letter addressed to the
         Trustee and dated such Delivery Date permitting the Trustee to rely on
         such counsel's opinions set forth in clauses (xxi) and (xxii) of
         Section 5(c) above.

                  authority (corporate and otherwise) necessary to own or hold
                  its properties and conduct the business in which it is
                  engaged.

                                    (ii) All of the issued shares of capital

         effect of which, in any such case set forth in clause (A) or (B), is,
         in the judgment of the Initial Purchaser, so material and adverse as to

         the delivery of the Notes being delivered on the applicable Delivery
         Date on the terms and in the manner contemplated in the Offering
         Memorandum and this Agreement.

         material adverse change in general domestic or international economic,
         political or financial conditions, including without limitation as a
         result of terrorist activities, or the effect of international
         conditions on the financial markets in the United States shall be such,
         as to make it, in the judgment of the Initial Purchaser impracticable
         or inadvisable to proceed with the public offering or delivery of the
         Notes being delivered on such Delivery Date on the terms and in the
         manner contemplated in the Offering Memorandum.

         The Company shall have furnished to the Initial Purchaser such further

believes to be QIBs, or, if any such person is buying for one or more
institutional accounts for which such person is acting as fiduciary or agent,
only when such person has represented to it that each such account is a QIB, to
whom notice has been given that such sale or delivery is being made in reliance
on Rule 144A in transactions under Rule 144A.

                  7. Indemnification and Contribution.

                           (a) The Company shall indemnify and hold harmless the

         action relating to purchases and sales of the Notes), to which the
         Initial Purchaser, director, officer, employee or controlling person
         may become subject, insofar as such loss, claim, damage, liability or
         action arises out of, or is based upon, (i) any untrue statement or
         alleged untrue statement of a material fact contained in any (A)
         Preliminary Offering Memorandum, the Offering Memorandum or in any
         amendment or supplement thereto or (B) materials or information

         referred to in any loss, claim, damage, liability or action arising out
         of or based upon matters covered by clause (i) or (ii) above (provided
         that, the Company shall not be liable under this clause (iii) to the
         extent that it is determined in a final judgment by a court of
         competent jurisdiction that such loss, claim, damage, liability or
         action resulted directly from any such acts or failures to act
         undertaken or omitted to be taken by the Initial Purchaser through its
         gross negligence or willful misconduct), and shall reimburse the
         Initial Purchaser and each such director, officer, employee or
         controlling person promptly upon demand for any legal or other expenses
         reasonably incurred by that Initial Purchaser, director, officer,

         liability or action as such expenses are incurred; provided, however,
         that the Company shall not be liable in any such case to the extent
         that any such loss, claim, damage, liability or action arises out of,
         or is based upon, any untrue statement or alleged untrue statement or
         omission or alleged omission made in any Preliminary Offering
         Memorandum, the Offering Memorandum, or in any such amendment or
         supplement, in reliance upon and in conformity with the written

         joint or several, or any action in respect thereof, to which the
         Company or any such director, officer, employee or controlling person
         may become subject, under the Securities Act or otherwise, insofar as
         such loss, claim, damage, liability or action arises out of, or is
         based upon, (i) any untrue statement or alleged untrue statement of a
         material fact contained in any Preliminary Offering Memorandum or the
         Offering Memorandum or in any amendment or supplement thereto or (ii)
         the omission or alleged omission to state in any Preliminary Offering
         Memorandum or the Offering Memorandum or in any amendment or supplement
         thereto, any material fact necessary to make the statements therein not
         misleading, but in each case only to the extent that the untrue
         statement or alleged untrue statement or omission or alleged omission
         was made in reliance upon and in conformity with the written
         information concerning the Initial Purchaser furnished to the Company
         by the Initial Purchaser specifically for inclusion therein and set
         forth in Section 7(e), and shall reimburse the Company and any such
         director, officer, employee or controlling person promptly upon demand
         for any legal or other expenses reasonably incurred by the Company or
         any such director, officer, employee or controlling person in
         connection with investigating or defending or preparing to defend
         against any such loss, claim, damage, liability or action as such
         expenses are incurred. The foregoing indemnity agreement is in addition
         to any liability which the Initial Purchaser may otherwise have to the
         Company or any such director, officer, employee or controlling person.

                           (c) Promptly after receipt by an indemnified party
         under this Section 7 of notice of any claim or the commencement of any
         action, the indemnified party shall, if a claim in respect thereof is
         to be made against the indemnifying party under this Section 7, notify
         the indemnifying party in writing of the claim or the commencement of
         that action; provided, however, that the failure to notify the
         indemnifying party shall not relieve it from any liability which it may
         have under this Section 7 except to the extent it has been materially
         prejudiced by such failure and, provided, further, that the failure to
         notify the indemnifying party shall not relieve it from any liability
         which it may have to an indemnified party otherwise than under this
         Section 7. If any such claim or action shall be brought against an
         indemnified party, and it shall notify the indemnifying party thereof,
         the indemnifying party shall be entitled to participate therein and, to
         the extent that it wishes, jointly with any other similarly notified
         indemnifying party, to assume the defense thereof with counsel
         satisfactory to the indemnified party. After notice from the
         indemnifying party to the indemnified party of its election to assume
         the defense of such claim or action, the indemnifying party shall not
         be liable to the indemnified party under this Section 7 for any legal
         or other expenses subsequently incurred by the indemnified party in
         connection with the defense thereof other than reasonable costs of
         investigation;
<PAGE>
                                                                              31

         provided, however, that the Initial Purchaser shall have the right to
         employ separate counsel to represent jointly the Initial Purchaser and
         their respective directors, officers, employees and controlling persons
         who may be subject to liability arising out of any claim in respect of
         which indemnity may be sought by the Initial Purchaser against the
         Company under this Section 7 if, in the reasonable judgment of the
         Initial Purchaser it is advisable for the Initial Purchaser and such
         directors, officers, employees and controlling persons to be jointly
         represented by separate counsel, and in that event the fees and
         expenses of such separate counsel shall be paid by the Company. No
         indemnifying party shall, (i) without the prior written consent of the
         indemnified parties (which consent shall not be unreasonably withheld),
         settle or compromise or consent to the entry of any judgment with
         respect to any pending or threatened claim, action, suit or proceeding
         in respect of which indemnification or contribution may be sought
         hereunder (whether or not the indemnified parties are actual or
         potential parties to such claim or action) unless such settlement,
         compromise or consent includes an unconditional release of each
         indemnified party from all liability arising out of such claim, action,
         suit or proceeding, or (ii) be liable for any settlement of any such
         action effected without its written consent (which consent shall not be
         unreasonably withheld), but if settled with its written consent or if
         there be a final judgment of the plaintiff in any such action, the
         indemnifying party agrees to indemnify and hold harmless any
         indemnified party from and against any loss or liability by reason of
         such settlement or judgment.

                           (d) If the indemnification provided for in this
         Section 7 shall for any reason be unavailable or insufficient to hold
         harmless an indemnified party under Section 7(a) or 7(b) in respect of
         any loss, claim, damage or liability, or any action in respect thereof,
         referred to therein, then each indemnifying party shall, in lieu of
         indemnifying such indemnified party, contribute to the amount paid or
         payable by such indemnified party as a result of such loss, claim,
         damage or liability, or action in respect thereof, (i) in such
         proportion as shall be appropriate to reflect the relative benefits
         received by the Company on the one hand and the Initial Purchaser on
         the other from the offering of the Notes, or (ii) if the allocation
         provided by clause (i) above is not permitted by applicable law, in
         such proportion as is appropriate to reflect not only the relative
         benefits referred to in clause (i) above but also the relative fault of
         the Company on the one hand and the Initial Purchaser on the other with
         respect to the statements or omissions or alleged statements or
         omissions which resulted in such loss, claim, damage or liability, or
         action in respect thereof, as well as any other relevant equitable
         considerations. The relative benefits received by the Company on the
         one hand and the Initial Purchaser on the other with respect to such
         offering shall be deemed to be in the same proportion as the total net
         proceeds from the offering of the Notes purchased under this Agreement
         (net of discounts and commissions but before deducting expenses)
         received by the Company on the one hand, and the total discounts and
         commissions received by the Initial Purchaser with respect to the Notes
         purchased under this Agreement, on the other hand, bear to the total
         gross proceeds from the offering of the Notes under this Agreement. The
         relative fault shall be determined by reference to whether the untrue
         or alleged untrue statement of a material fact or omission or alleged
         omission to state a material fact relates to information supplied by
         the Company or the Initial Purchaser, the intent of the parties and
         their relative knowledge, access to information and opportunity to
         correct or prevent such
<PAGE>
                                                                              32

         statement or omission. The Company and the Initial Purchaser agree that
         it would not be just and equitable if contributions pursuant to this
         Section 7(d) were to be determined by pro rata allocation or by any
         other method of allocation which does not take into account the
         equitable considerations referred to herein. The amount paid or payable
         by an indemnified party as a result of the loss, claim, damage or
         liability, or action in respect thereof, referred to above in this
         Section shall be deemed to include, for purposes of this Section 7(d),
         any legal or other expenses reasonably incurred by such indemnified
         party in connection with investigating or defending any such action or
         claim. Notwithstanding the provisions of this Section, no Initial
         Purchaser shall be required to contribute any amount in excess of the
         amount by which the total price at which the Notes resold by it in the
         initial placement of such Notes were offered to investors exceeds the
         amount of any damages which the Initial Purchaser has otherwise paid or
         become liable by reason of any untrue or alleged untrue statement or
         omission or alleged omission. No person guilty of fraudulent
         misrepresentation (within the meaning of Section 11(f) of the
         Securities Act) shall be entitled to contribution from any person who
         was not guilty of such fraudulent misrepresentation.

                           (e) The Initial Purchaser confirms, and the Company
         acknowledges, that the statements in paragraph numbers 3, 7, 8, 9, the
         last sentence of paragraph 5 and the first two sentences of paragraph
         15 under the caption "Plan of Distribution" in the Offering Memorandum
         are correct and constitute the only information concerning the Initial
         Purchaser furnished in writing to the Company by or on behalf of the
         Initial Purchaser specifically for inclusion in the Offering
         Memorandum.

                  8. Termination. The obligations of the Initial Purchaser
hereunder may be terminated by the Initial Purchaser by notice given to and
received by the Company prior to delivery of and payment for the Notes if, prior
to that time, any of the events described in Sections 5(m) or 5(n) shall have
occurred or if the Initial Purchaser shall decline to purchase the Firm Notes
for any reason permitted under this Agreement.

                  9. Reimbursement of Initial Purchaser's Expenses.

                           (a) If (i) the Company fails to tender the Notes for
         delivery to the Initial Purchaser by reason of any failure, refusal or
         inability on the part of the Company to perform any agreement on its
         part to be performed, or because any other condition of the Initial
         Purchaser's obligations hereunder required to be fulfilled by the
         Company is not fulfilled or (ii) the Initial Purchaser declines to
         purchase the Notes for any reason permitted under this Agreement
         (including the termination of this Agreement pursuant to Section 8),
         the Company shall reimburse the Initial Purchaser for all reasonable
         out-of-pocket expenses (including fees and disbursements of counsel)
         incurred by the Initial Purchaser in connection with this Agreement and
         the proposed purchase of the Notes, and upon demand the Company shall
         pay the full amount thereof to the Initial Purchaser.

                           (b) The Company shall reimburse the Initial Purchaser
         for all out-of-pocket expenses incurred by the Initial Purchaser in
         connection with the purchase and delivery of Pledged Securities on
         behalf of the Company pursuant to Section 2(c) hereof, and upon demand
         the Company shall pay the full amount thereof to the Initial Purchaser.

                            LOCK-UP LETTER AGREEMENT

Lehman Brothers Inc.
745 Seventh Avenue
New York, New York 10019

Dear Ladies and Gentlemen:

         The undersigned understands that you propose to enter into a purchase
agreement (the "PURCHASE Agreement") providing for the purchase by you (the
"INITIAL PURCHASER") of Convertible Senior Notes due 2009 (the "NOTES") of
Mindspeed Technologies, Inc., a Delaware corporation (the "COMPANY"), which are
convertible into fully paid, non-assessable shares of common stock, par value
$0.01 per share, of the Company (the "COMMON STOCK"), and that the Initial
Purchaser proposes to reoffer the Notes to certain qualified institutional
buyers under Rule 144A of the Securities Act of 1933, as amended (the
"OFFERING").

         In consideration of the execution of the Purchase Agreement by the
Initial Purchaser, and for other good and valuable consideration, the
undersigned hereby irrevocably agrees that, without the prior written consent of
the Initial Purchaser, the undersigned will not, directly or indirectly, (1)
offer for sale, sell, pledge or otherwise dispose of (or enter into any
transaction or device which is designed to, or could be expected to, result in
the disposition by any person at any time in the future of) any shares of Common
Stock or any securities convertible into or exchangeable for Common Stock or
substantially similar securities (or exercise any right to require the Company
to register any such securities under the Securities Act of 1933, as amended) or
sell or grant options, warrants or rights with respect to any shares of Common
Stock or securities convertible into or exchangeable for Common Stock or
substantially similar securities (the "LOCK-UP SHARES") or (2) enter into any
swap or other derivatives transaction that transfers to another, in whole or in
part, any of the economic benefits or risks of ownership of such shares of
Common Stock, whether any such transaction described in clause (1) or (2) above
is to be settled by delivery of Common Stock or other securities, in cash or
otherwise, for a period of 90 days after the date of the final Offering
Memorandum relating to the Offering.

         Notwithstanding the foregoing, if (1) during the last 17 days of the
90-day restricted period the Company issues an earnings release or material news
or a material event relating to the Company occurs or (2) prior to the
expiration of the 90-day restricted period, the Company announces that it will
release earnings results during the 16-day period beginning on the last day of
the 90-day period, then the restrictions imposed by this letter shall continue
to apply until the expiration of the 18-day period beginning on the issuance of
the earnings release or the occurrence of the material news or material event.

         Notwithstanding the foregoing, the undersigned may transfer any or all
Lock-Up Shares (i) as a bona fide gift or gifts, provided that the donee or
donees thereof have executed and delivered to the Initial Purchaser a written
agreement providing their agreement to be bound by the restrictions set forth
herein, (ii) to any trust, partnership, limited liability company or other legal
entity commonly used for estate planning purposes which is established for the
direct or

                                      A-2
<PAGE>
indirect benefit of the undersigned or the immediate family of the undersigned,
provided that the trustee, general partner, manager or other administrator, as
the case may be, has executed and delivered to the Initial Purchaser a written
agreement providing their agreement to be bound by the restrictions set forth
herein, and provided further that any such transfer shall not involve a
disposition for value, (iii) any 10b5-1 trading plan in existence on the date
hereof, or (iv) with the prior written consent of the Initial Purchaser. For
purposes of this Lock-Up Letter Agreement, "immediate family" shall mean any
relationship by blood, marriage or adoption, not more remote than first cousin.
Notwithstanding the foregoing, if options for Common Stock held by the
undersigned that are exercisable shall expire during the lock-up period
described herein unless exercised, the undersigned may exercise such options and
sell such number of shares received upon exercise to the extent necessary to
satisfy obligations under a cashless exercise arrangement, without the consent
of the Initial Purchaser, provided the shares issued upon the exercise of such
options shall be subject the terms of this Lock-Up Letter Agreement and deemed
Lock-Up Shares except to the extent sold pursuant to such cashless exercise.

         In furtherance of the foregoing, the Company and its transfer agent are
hereby authorized to decline to make any transfer of securities if such transfer
would constitute a violation or breach of this Lock-Up Letter Agreement.

         The undersigned understands that the Company and the Initial Purchaser
will proceed with the Offering in reliance on this Lock-Up Letter Agreement.
Whether or not the Offering actually occurs depends on a number of factors,
including market conditions. Any Offering will only be made pursuant to the
Purchase Agreement, the terms of which are subject to negotiation between the
Company and the Initial Purchaser. In addition, it is understood that, if the
Company notifies you that it does not intend to proceed with the Offering, if
the Purchase Agreement is not executed, or if the Purchase Agreement (other than
the provisions thereof which survive termination) shall terminate or be
terminated prior to payment for and delivery of the Notes, the undersigned will
be released from its obligations under this Lock-Up Letter Agreement.

         This Lock-Up Letter Agreement shall be governed by, and construed in
accordance with, the laws of the State of New York.

         The undersigned hereby represents and warrants that the undersigned has
full power and authority to enter into this Lock-Up Letter Agreement and that,
upon request, the undersigned will execute any additional documents necessary in
connection with the enforcement hereof. Any obligations of the undersigned shall
be binding upon the heirs, personal representatives, successors and assigns of
the undersigned.

                                  Very truly yours,
                                  [NAME]
