ITEM 15. INDEMNIFICATION OF OFFICERS AND DIRECTORS.

     Section 145 of the Delaware General Corporation law ("DGCL") empowers a
Delaware corporation to indemnify any persons who are, or are threatened to be
made, parties to any threatened, pending or completed legal action, suit or
proceedings, whether civil, criminal, administrative or investigative (other
than action by or in the right of such corporation), by reason of the fact that
such person was an officer or director of such corporation, or is or was serving
at the request of such corporation as a director, officer, employee or agent of
another corporation or enterprise. The indemnity may include expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding, provided that such officer or director acted in good faith and in a
manner he reasonably believed to be in or not opposed to the corporation's best
interest, and, for criminal proceedings, had no reasonable cause to believe his
conduct was illegal. A Delaware corporation may indemnify officers and directors
in an action by or in the right of the corporation under the same conditions,
except that no indemnification is permitted without judicial approval if the
officer or director is adjudged to be liable to the corporation in the
performance of his duty. Where an officer or director is successful on the
merits or otherwise in the defense of any action referred to above, the
corporation must indemnify him against the expenses which such officer or
director actually and reasonably incurred.

     In accordance with the DGCL, the Registrant's Restated Certificate of
Incorporation ("Certificate"), contains a provision to limit the personal
liability of the directors of the Registrant for violations of their fiduciary
duty. This provision eliminates each director's liability to the Registrant or
its stockholders for monetary damages except (i) for any breach of the
director's duty of loyalty to the Registrant or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the DGCL providing for
liability of directors for unlawful payment of dividends or unlawful stock
purchases or redemptions, or (iv) for any transaction from which a director
derived an improper personal benefit. The effect of this provision is to
eliminate the personal liability of directors for monetary damages for actions
involving a breach of their fiduciary duty of care, including any such actions
involving gross negligence.

     The Registrant's Certificate and the Registrant's Bylaws provide for
indemnification of the officers and directors of the Registrant to the fullest
extent permitted by applicable law.

     The Registrant has entered into indemnification agreements with each
director and executive officer which provide indemnification to such directors
and executive officers under certain circumstances for acts or omissions which
may not be covered by directors' and officers' liability insurance.

ITEM 17. UNDERTAKINGS.

     The undersigned Registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this Registration Statement: (i) to
     include any prospectus required by section 10(a)(3) of the Securities Act;
     (ii) to reflect in the prospectus any facts or events arising after the
     effective date of the Registration Statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     Registration Statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) (Section 230.424(b) of this chapter) if, in the
     aggregate, the changes in volume and price represent no more than a 20%
     change in the maximum aggregate offering price set forth in the
     "Calculation of Registration Fee" table in the effective registration
     statement; and (iii) to include any material information with respect to
     the plan of distribution not previously disclosed in the Registration
     Statement or any material change to such information in the Registration
     Statement; provided, however, that (i) and (ii) do not apply if the
     Registration Statement is on Form S-3, Form S-8 or Form F-3, and the
     information required to be included in a post-effective amendment by (i)
     and (ii) is contained in periodic reports filed with or furnished to the
     Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
     Exchange Act that are incorporated by reference in the Registration
     Statement.

          (2) That, for the purpose of determining any liability under the
     Securities Act, each such post-effective amendment shall be deemed to be a
     new registration statement relating to the securities offered therein, and
     the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the Registration Statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

                                      II-2
<PAGE>   5

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described in Item 15 above, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against liabilities (other than the payment of the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

     The undersigned Registrant hereby undertakes that:

          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.

          (2) For the purpose of determining liability under the Securities Act
     of 1933, each post-effective amendment that contains a form of prospectus
     shall be deemed to be a new registration statement relating to the
     securities offered therein, and the offering of such securities at that
     time shall be deemed to be a new registration statement relating to the
     securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

PRUDENTIAL SECURITIES INCORPORATED
C.E. UNTERBERG, TOWBIN
STEPHENS INC.
As Representatives of the Several Underwriters
c/o Prudential Securities Incorporated
One New York Plaza
New York, New York  10292

Ladies and Gentlemen:

       TelCom Semiconductor, Inc., a Delaware corporation (the "Company"), and
certain stockholders of the Company named in Schedule 2 hereto (the "Selling
Securityholders"), hereby confirm their agreements with the several underwriters
named in Schedule 1 hereto (the "Underwriters"), for whom you have been duly
authorized to act as representatives (in such capacities, the
"Representatives"), as set forth below. If you are the only Underwriters, all
references herein to the Representatives shall be deemed to be to the
Underwriters.

       1. Securities. Subject to the terms and conditions herein contained, the
Company and Selling Securityholders propose to issue and sell to the several
Underwriters an aggregate of 3,190,000 shares (the "Firm Securities") of the
Company's Common Stock, par value $.001 ("Common Stock"). The number of Firm
Securities to be sold by each Selling Securityholder is set forth opposite such
Selling Securityholder's name on Schedule 2 hereto. The Company and the Selling
Securityholders also propose to issue and sell to the several Underwriters not
more than an aggregate of 478,500 additional shares of Common Stock if requested
by the Representatives as provided in Section 4 of this Agreement. Any and all
shares of Common Stock to be purchased by the Underwriters pursuant to such
option are referred to herein as the "Option Securities", and the Firm
Securities and any Option Securities are collectively referred to herein as the
"Securities".

       2. Representations and Warranties of the Company. The Company represents
and warrants to, and agrees with, each of the several Underwriters that:

       (a) The Company meets the requirements for use of Form S3 under the
Securities Act of 1933, as amended (the "Act"). A registration statement on such
Form (File No. 333-30910) with respect to the Securities, including a prospectus
subject to completion, has been filed by the Company with the Securities and
Exchange Commission (the "Commission") under the Act, and one or more amendments
to such registration statement may have been so filed. After the execution of

by reference therein filed under the Exchange Act; the term "Prospectus" means:

        (A)  if the Company relies on Rule 434 under the Act, the Term Sheet
             relating to the Securities that is first filed pursuant to Rule
             424(b)(7) under the Act, together with the preliminary Prospectus
             identified therein that such Term Sheet supplements:

        (B)  if the Company does not rely on Rule 434 under the Act, the
             prospectus first filed with the Commission pursuant to Rule 424(b)
             under the Act; or

        (C)  if the Company does not rely on Rule 434 under the Act and if no

             requirements of Rule 434 under the Act. Any reference in this
             Agreement to an "amendment or supplement" to any Preliminary
             Prospectus or the Prospectus or any Integrated Prospectus or an
             "amendment" to any registration statement (including the
             Registration Statement) shall be deemed to include any document
             incorporated by reference therein that is filed with the Commission

<PAGE>   3
Prospectus, Integrated Prospectus or registration statement, as the case may be;
any reference herein to the "date" of a Prospectus that includes a Term Sheet
shall mean the date of such Term Sheet. For purposes of the preceding sentence,
any reference to the "effective date" of an amendment to a registration
statement shall, if such amendment is effected by means of the filing with the
Commission under the Exchange Act of a document incorporated by reference in
such registration statement, be deemed to refer to the date on which such
document was so filed with the Commission.

          (b) The Commission has not issued any order preventing or suspending
      the use of any Preliminary Prospectus. When any Preliminary Prospectus and
      any amendment or supplement thereto was filed with the Commission, it (i)
      contained all statements required to be stated therein in accordance with,
      and complied in all material respects with the requirements of, the Act,
      the Exchange Act and the respective rules and regulations of the
      Commission thereunder, and (ii) did not include any untrue statement of a
      material fact or omit to state any material fact necessary in order to
      make the statements therein, in the light of the circumstances under which
      they were made, not misleading. When the Registration Statement or any
      amendment thereto was or is declared effective, it (i) contained or will
      contain all statements required to be stated therein in accordance with,
      and complied or will comply in all material respects with the requirements
      of, the Act, the Exchange Act and the respective rules and regulations of
      the Commission thereunder and (ii) did not or will not include any untrue
      statement of a material fact or omit to state any material fact necessary
      to make the statements therein not misleading. When the Prospectus or any
      Term Sheet that is a part thereof or any Integrated Prospectus or any
      amendment or supplement to the Prospectus is filed with the Commission
      pursuant to Rule 424(b) (or, if the Prospectus or part thereof or such
      amendment or supplement is not required to be so filed, when the
      Registration Statement or the amendment thereto containing such amendment
      or supplement to the Prospectus was or is declared effective), on the date
      when the Prospectus is otherwise amended or supplemented and on the Firm
      Closing Date and any Option Closing Date (both as hereinafter defined),
      each of the Prospectus, and, if required to be filed pursuant to Rules
      434(c)(2) and 424(b) under the Act, the Integrated Prospectus as amended
      or supplemented at any such time, (i) contained or will contain all
      statements required to be stated therein in accordance with, and complied
      or will comply in all material respects with the requirements of, the Act,
      the Exchange Act and the respective rules and regulations of the
      Commission thereunder and (ii) did not or will not include any untrue
      statement of a material fact or omit to state any material fact necessary
      in order to make the statements therein, in the light of the circumstances
      under which they were made, not misleading. The foregoing provisions of
      this paragraph (b) do not apply to statements or omissions made in any
      Preliminary Prospectus or any amendment or supplement thereto, the
      Registration Statement or any amendment thereto or the Prospectus or, if
      required to be filed pursuant to Rules 434(c)(2) and 424(b) and the Act,
      the Integrated Prospectus or any amendment or supplement thereto in
      reliance upon and in conformity with written information furnished to the
      Company by any Underwriter through the Representatives specifically for
      use therein.

          (c) If the Company has elected to rely on Rule 462(b) and the Rule
      462(b) Registration Statement has not been declared effective (i) the
      Company has filed a Rule 462(b) Registration Statement in compliance with
      and that is effective upon filing pursuant to Rule 462(b) and (ii) the
      Company has given irrevocable instructions for transmission of the
      applicable filing fee in connection with the filing of the Rule 462(b)
      Registration Statement, in compliance with Rule 111 promulgated under the
      Act or the Commission has received payment of such filing fee.

          (d) The Company and each of its subsidiaries have been duly organized
      and are validly existing as corporations in good standing under the laws
      of their respective jurisdictions of

<PAGE>   4

      incorporation and are duly qualified to transact business as foreign
      corporations and are in good standing under the laws of all other
      jurisdictions where the ownership or leasing of their respective
      properties or the conduct of their respective businesses requires such
      qualification, except where the failure to be so qualified does not amount
      to a material liability or disability to the Company and its subsidiaries,
      taken as a whole.

          (e) The Company and each of its subsidiaries have full power
      (corporate and other) to own or lease their respective properties and
      conduct their respective businesses as described in the Registration
      Statement and each of the Prospectus and any Integrated Prospectus or, if
      the Prospectus is not in existence, the most recent Preliminary
      Prospectus; and the Company has full power (corporate and other) to enter
      into this Agreement and to carry out all the terms and provisions hereof
      to be carried out by it.

          (f) The issued shares of capital stock of each of the Company's
      subsidiaries have been duly authorized and validly issued, are fully paid
      and nonassessable and, except for directors' qualifying shares and as

      Prospectus or, if the Prospectus and any required Integrated Prospectus
      are not in existence, the most recent Preliminary Prospectus, are owned
      beneficially by the Company free and clear of any security interests,
      liens, encumbrances, equities or claims.

          (g) The Company has an authorized, issued and outstanding
      capitalization as set forth in each of the Prospectus and any Integrated
      Prospectus or, if the Prospectus and any required Integrated Prospectus
      are not in existence, the most recent Preliminary Prospectus. All of the
      issued shares of capital stock of the Company have been duly authorized
      and validly issued and are fully paid and nonassessable. The Firm
      Securities and the Option Securities have been duly authorized and at the
      Firm Closing Date or the related Option Closing Date (as the case may be),
      after payment therefor in accordance herewith, will be validly issued,
      fully paid and nonassessable. No holders of outstanding shares of capital
      stock of the Company are entitled as such to any preemptive or other
      rights to subscribe for any of the Securities, and no holder of securities
      of the Company has any right which has not been fully exercised or waived
      to require the Company to register the offer or sale of any securities
      owned by such holder under the Act in the public offering contemplated by
      this agreement.

          (h) The capital stock of the Company conforms to the description
      thereof contained in each of the Prospectus and any Integrated Prospectus
      or, if the Prospectus and any required Integrated Prospectus are not in

          (i) Except as disclosed in the Prospectus or each of the Prospectus
      and any Integrated Prospectus (or, if the Prospectus and any required
      Integrated Prospectus are not in existence, the most recent Preliminary
      Prospectus), there are not outstanding (A) securities or obligations of
      the Company or any of its subsidiaries convertible into or exchangeable
      for any capital stock of the Company or any such subsidiary, (B) warrants,
      rights or options to subscribe for or purchase from the Company or any
      such subsidiary any such capital stock or any such convertible or
      exchangeable securities or obligations, or (C) obligations of the Company
      or any such subsidiary to issue any shares of capital stock, any such
      convertible or exchangeable securities or obligations, or any such
      warrants, rights or options.

          (j) The consolidated financial statements and schedules of the Company
      and its consolidated subsidiaries included in the Registration Statement
      and the Prospectus or each of the Prospectus and any Integrated Prospectus
      (or, if the Prospectus and any required Integrated Prospectus are not in
      existence, the most recent Preliminary Prospectus) fairly present the


                                      -4-

      financial position of the Company and its consolidated subsidiaries and
      the results of operations and changes in financial condition as of the
      dates and periods therein specified. Such financial statements and
      schedules have been prepared in accordance with generally accepted
      accounting principles consistently applied throughout the periods involved
      (except as otherwise noted therein). The selected financial data set forth
      under the caption "Selected Consolidated Financial Information" in the
      Prospectus or each of the Prospectus and any Integrated Prospectus (or, if
      the Prospectus and any required Integrated Prospectus are not in
      existence, the most recent Preliminary Prospectus), fairly present, on the
      basis stated in each of the Prospectus and any Integrated Prospectus (or
      such Preliminary Prospectus) and such Annual Report, the information
      included therein.

          (k) To the Company's knowledge, PricewaterhouseCoopers LLP, who have
      certified certain financial statements of the Company and its consolidated
      subsidiaries and delivered their report with respect to the audited
      consolidated financial statements and schedules included in the
      Registration Statement, the Prospectus and any Integrated Prospectus (or,
      if the Prospectus and any required Integrated Prospectus are not in
      existence, the most recent Preliminary Prospectus), are independent public
      accountants as required by the Act, the Exchange Act and the related
      published rules and regulations thereunder.

          (l) The execution and delivery of this Agreement have been duly
      authorized by the Company and this Agreement has been duly executed and
      delivered by the Company, and is the valid and binding agreement of the
      Company, enforceable against the Company in accordance with its terms,
      except as rights to indemnification or contribution hereunder may be
      limited by applicable law and except as the enforcement hereof may be
      limited by bankruptcy, insolvency, reorganization, moratorium or other
      similar laws relating to or affecting the rights and remedies of creditors
      or by general equitable principles.

          (m) No legal or governmental proceedings are pending to which the
      Company or any of its subsidiaries is a party or to which the property of
      the Company or any of its subsidiaries is subject that are required to be
      described in the Registration Statement or the Prospectus or each of the
      Prospectus and any Integrated Prospectus (or, if the Prospectus and any
      required Integrated Prospectus are not in existence, the most recent
      Preliminary Prospectus), and, to the Company's knowledge, no such
      proceedings have been threatened against the Company or any of its
      subsidiaries or with respect to any of their respective properties; and no
      contract or other document is required to be described in the Registration
      Statement or the Prospectus or any Integrated Prospectus or to be filed as
      an exhibit to the Registration Statement that is not described therein

      existence, the most recent Preliminary Prospectus) or filed as required.

          (n) The issuance, offering and sale of the Securities to the
      Underwriters by the Company pursuant to this Agreement, the compliance by
      the Company with the other provisions of this Agreement and the
      consummation of the other transactions herein contemplated do not (i)
      require the consent, approval, authorization, registration or
      qualification of or with any governmental authority, except such as have
      been obtained, such as may be required under state securities or blue sky
      laws or the rules and regulations of the NASD and, if the registration
      statement filed with respect to the Securities (as amended) is not
      effective under the Act as of the time of execution hereof, such as may be
      required (and shall be obtained as provided in this Agreement) under the
      Act, or (ii) conflict with or result in a breach or violation of any of
      the terms and provisions of, or constitute a default under, any indenture,
      mortgage, deed of trust, lease or other agreement or instrument to which
      the Company or any of its subsidiaries is a party or by which the Company
      or any of its subsidiaries or any of their respective properties are
      bound, or the charter documents or

      judgment, decree, order, rule or regulation of any court or other
      governmental authority or any arbitrator applicable to the Company or any

      which would not result in a material adverse change in the condition
      (financial or otherwise), management, business, prospects, net worth or
      results of operations of the Company and its subsidiaries, taken as a

      proceeding and there has not been any material adverse change, or any
      development involving a prospective material adverse change, in the
      condition (financial or otherwise), management, business, prospects, net
      worth, or results of operations of the Company or its subsidiaries, taken
      as a whole, except in each case as described in or contemplated by the
      Prospectus or, if each of the Prospectus and any Integrated Prospectus or,
      if the Prospectus and any required Integrated Prospectus are not in
      existence, the most recent Preliminary Prospectus.

          (p) The Company has not, directly or indirectly, (i) taken any action
      designed to cause or to result in, or that has constituted or which might

      of the Securities or (ii) since the filing of the Registration Statement
      (A) sold, bid for, purchased, or paid anyone any compensation for
      soliciting purchases of, the Securities or (B) paid or agreed to pay to

          (q) The Company has not distributed and, prior to the later of (i) the
      Closing Date and (ii) the completion of the distribution of the
      Securities, will not distribute any offering material in connection with

      the most recent Preliminary Prospectus) other than pursuant to the
      Company's stock option plans or employee stock purchase plan or as
      otherwise contemplated by the Prospectus.

          (s) The Company and each of its subsidiaries have good and marketable
      title in fee simple to all items of real property and marketable title to
      all personal property owned by each of them, in each case free and clear
      of any security interests, liens, encumbrances, equities, claims and other
      defects, except such as do not materially and adversely affect the value
      of such property and do not interfere in any material respect with the use
      made or proposed to be


                                      -6-
<PAGE>   7

      made of such property by the Company or such subsidiary, and any real
      property and buildings held under lease by the Company or any such
      subsidiary are held under valid, subsisting and enforceable leases, with
      such exceptions as are not material and do not interfere with the use made
      or proposed to be made of such property and buildings by the Company or
      such subsidiary, in each case except as described in or contemplated by
      the Prospectus (or, if the Prospectus is not in existence, the most recent
      Preliminary Prospectus).

          (t) No labor dispute with the employees of the Company or any of its
      subsidiaries exists or, to the Company's knowledge, is threatened or
      imminent that could result in a material adverse change in the condition
      (financial or otherwise), business, prospects, net worth or results of
      operations of the Company and its subsidiaries taken as a whole, except as
      described in or contemplated by the Prospectus (or, if the Prospectus is

      service marks, trade names, licenses, copyrights and proprietary or other
      confidential information currently employed by them in connection with
      their respective businesses, and neither the Company nor any such
      subsidiary has received any notice of infringement of or conflict with
      asserted rights of any third party with respect to any of the foregoing
      which, singly or in the aggregate, if the subject of an unfavorable
      decision, ruling or finding, would result in a material adverse change in
      the condition (financial or otherwise), business, prospects, net worth or
      results of operations of the Company and its subsidiaries taken as a
      whole, except as described in or contemplated by the Prospectus (or, if
      the Prospectus is not in existence, the most recent Preliminary
      Prospectus).

          (v) The Company and each of its subsidiaries are insured by insurers
      of recognized financial responsibility against such losses and risks and
      in such amounts as are prudent and customary in the businesses in which
      they are engaged; neither the Company nor any such subsidiary has been
      refused any insurance coverage sought or applied for; and neither the
      Company nor any such subsidiary 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 as may be
      necessary to continue its business at a cost that would not materially and
      adversely affect the condition (financial or otherwise), business,
      prospects, net worth or results of operations of the Company and its
      subsidiaries taken as a whole, except as described in or contemplated by
      the Prospectus (or, if the Prospectus is not in existence, the most recent
      Preliminary Prospectus).

      other distribution on such subsidiary's capital stock, from repaying to
      the Company any loans or advances to such subsidiary from the Company or
      from transferring any of such subsidiary's property or assets to the
      Company or any other subsidiary of the Company, except as described in or
      contemplated by the Prospectus (or, if the Prospectus is not in existence,
      the most recent Preliminary Prospectus).

          (x) The Company and its subsidiaries possess all material
      certificates, authorizations and permits issued by the appropriate
      federal, state or foreign regulatory authorities necessary to conduct
      their respective businesses, and neither the Company nor any such
      subsidiary has received any notice of proceedings relating to the
      revocation or modification of any such certificate, authorization or
      permit which, singly or in the aggregate, if the subject of an unfavorable
      decision, ruling or finding, would result in a material adverse change in
      the condition (financial or otherwise), business, prospects, net worth or
      results of operations of the


                                      -7-
<PAGE>   8

      Company and its subsidiaries taken as a whole, except as described in
      or contemplated by the Prospectus (or, if the Prospectus is not in
      existence, the most recent Preliminary Prospectus).

          (y) The Company will conduct its operations in a manner that will not
      subject it to registration as an investment company under the Investment
      Company Act of 1940, as amended, and this transaction will not cause the
      Company to become an investment company subject to registration under such
      Act.

          (z) The Company has filed all foreign, federal, state and local tax
      returns that are required to be filed or has requested extensions thereof
      (except in any case in which the failure so to file would not have a
      material adverse effect on the Company and its subsidiaries taken as a
      whole) and has paid all taxes required to be paid by it and any other
      assessment, fine or penalty levied against it, to the extent that any of
      the foregoing is due and payable, except for any such assessment, fine or
      penalty that is currently being contested in good faith or as described in
      or contemplated by the Prospectus (or, if the Prospectus is not in
      existence, the most recent Preliminary Prospectus).

          (aa) Neither the Company nor any of its subsidiaries is in violation
      of any federal or state law or regulation relating to occupational safety
      and health or to the storage, handling or transportation of hazardous or
      toxic materials and the Company and its subsidiaries have received all
      permits, licenses or other approvals required of them under applicable
      federal and state occupational safety and health and environmental laws
      and regulations to conduct their respective businesses, and the Company
      and each such subsidiary is in compliance with all terms and conditions of
      any such permit, license or approval, except any such violation of law or
      regulation, failure to receive required permits, licenses or other
      approvals or failure to comply with the terms and conditions of such
      permits, licenses or approvals which would not, singly or in the
      aggregate, result in a material adverse change in the condition (financial
      or otherwise), business, prospects, net worth or results of operations of
      the Company and its subsidiaries taken as a whole, except as described in
      or contemplated by the Prospectus (or, if the Prospectus is not in
      existence, the most recent Preliminary Prospectus).

          (bb) Each certificate signed by any officer of the Company and
      delivered to the Representatives or counsel for the Underwriters shall be
      deemed to be a representation and warranty by the Company to each
      Underwriter as to the matters covered thereby.

          (cc) Except for the shares of capital stock of each of the
      subsidiaries owned by the Company and such subsidiaries, neither the
      Company nor any such subsidiary owns any shares of stock or any other
      equity securities of any corporation or has any equity interest in any
      firm, partnership, association or other entity, except as described in or
      contemplated by the Prospectus (or, if the Prospectus is not in existence,
      the most recent Preliminary Prospectus).

          (dd) The Company and each of its subsidiaries maintain a system of
      internal accounting controls sufficient to provide reasonable assurance
      that (1) transactions are executed in accordance with management's general
      or specific authorizations; (2) transactions are recorded as necessary to
      permit preparation of financial statements in conformity with generally
      accepted accounting principles and to maintain asset accountability; (3)
      access to assets is permitted only in accordance with management's general
      or specific authorization; and (4) the recorded accountability for assets
      is compared with the existing assets at reasonable intervals and
      appropriate action is taken with respect to any differences.

          (ee) No default exists, and no event has occurred which, with notice
      or lapse of time or



                                      -8-

      both, would constitute a default in the due performance and observance
      of any term, covenant or condition of any material indenture, mortgage,
      deed of trust, lease or other agreement or instrument to which the Company
      or any of its subsidiaries is a party or by which the Company or any of
      its subsidiaries or any of their respective properties is bound or may be
      affected in any material adverse respect with regard to property, business
      or operations of the Company and its subsidiaries.

          (ff) The Company has no significant subsidiaries within the meaning of
      Section 210-02(w) of Regulation S-X other than TelCom Hong Kong, Ltd. (the
      "Hong Kong Subsidiary").

          3. Representations and Warranties of the Selling Securityholders.

        Each Selling Securityholder severally and not jointly represents and
      warrants to, and agrees with, each of the several Underwriters that:

          (a) Such Selling Securityholder has full power to enter into this
      Agreement and to sell, assign, transfer and deliver to the Underwriters
      the Securities to be sold by such Selling Securityholder hereunder in
      accordance with the terms of this Agreement, and this Agreement has been
      duly executed and delivered by such Selling Securityholder.

          (b) Such Selling Securityholder has duly executed and delivered a
      power of attorney and custody agreement (with respect to such Selling
      Securityholder, the "Power of Attorney" and the "Custody Agreement",
      respectively), each in the form heretofore delivered to the
      Representatives, appointing Phillip M. Drayer and Robert G. Gargus as such
      Selling Securityholder's attorney in fact (the "Attorney in Fact") with
      authority to execute, deliver and perform this Agreement on behalf of such
      Selling Securityholder and appointing Chasemellon Shareholder Services, as
      custodian thereunder (the "Custodian"). Certificates in negotiable form,
      endorsed in blank or accompanied by blank stock bond powers duly executed,
      with signatures appropriately guaranteed, representing the Securities to
      be sold by such Selling Securityholder hereunder have been deposited with
      the Custodian pursuant to the Custody Agreement for the purpose of
      delivery pursuant to this Agreement. Such Selling Securityholder has full
      power to enter into the Custody Agreement and the Power of Attorney and to
      perform its obligations under the Custody Agreement. The Custody Agreement
      and the Power of Attorney have been duly executed and delivered by such
      Selling Securityholder and, assuming due authorization, execution and
      delivery by the Custodian, are the legal, valid, binding and enforceable
      instruments of such Selling Securityholder, except as rights to
      indemnification or contribution hereunder may be limited by applicable law
      and except as the enforcement hereof may be limited by bankruptcy,
      insolvency, reorganization, moratorium or other similar laws relating to
      or affecting the rights and remedies of creditors or by general equitable
      principles. Such Selling Securityholder agrees that each of the Securities
      represented by the certificates on deposit with the Custodian is subject
      to the interests of the Underwriters hereunder, that the arrangements made
      for such custody, the appointment of the Attorney in Fact and the right,
      power and authority of the Attorney in Fact to execute and deliver this
      Agreement, to agree on the price at which the Securities (including such
      Selling Securityholder's Securities) are to be sold to the Underwriters,
      and to carry out the terms of this Agreement, are to that extent
      irrevocable and that the obligations of such Selling Securityholder
      hereunder shall not be terminated, except as provided in this Agreement or
      the Custody Agreement, by any act of such Selling Securityholder, by
      operation of law or otherwise, whether in the case of any individual
      Selling Securityholder by the death or incapacity of such Selling
      Securityholder, in the case of a trust or estate by the death of the
      trustee or trustees or the executor or executors or the termination of
      such trust or estate, or in the case of a corporate or partnership Selling


                                      -9-
<PAGE>   10

      Securityholder by its liquidation or dissolution or by the occurrence of
      any other event. If any individual Selling Securityholder, trustee or
      executor should die or become incapacitated or any such trust should be
      terminated, or if any corporate or partnership Selling Securityholder
      shall liquidate or dissolve, or if any other event should occur, before
      the delivery of such Securities hereunder, the certificates for such
      Securities deposited with the Custodian shall be delivered by the
      Custodian in accordance with the respective terms and conditions of this
      Agreement as if such death, incapacity, termination, liquidation or
      dissolution or other event had not occurred, regardless of whether or not
      the Custodian or the Attorney in Fact shall have received notice thereof.

          (c) Such Selling Securityholder is the lawful owner of the Securities
      to be sold by such Selling Securityholder hereunder and upon sale and
      delivery of, and payment for, such Securities, as provided herein, such
      Selling Securityholder will convey good and marketable title to such
      Securities, free and clear of any security interests, liens, encumbrances,
      equities, claims or other defects.

          (d) Such Selling Securityholder has not, directly or indirectly, (i)
      taken any action designed to cause or result in, or that has constituted
      or which might reasonably be expected to constitute, the stabilization or
      manipulation of the price of any security of the Company to facilitate the
      sale or resale of the Securities or (ii) since the filing of the
      Registration Statement (A) sold, bid for, purchased, or paid anyone any
      compensation for soliciting purchases of, the Securities or (B) paid or
      agreed to pay to any person any compensation for soliciting another to
      purchase any other securities of the Company (except for the sale of
      Securities under this Agreement.

          (e) To the extent that any statements or omissions are made in the
      Registration Statement, any Preliminary Prospectus, the Prospectus or any
      amendment or supplement thereto in reliance upon and in conformity with
      written information furnished to the Company by such Selling
      Securityholder specifically for use therein, such Preliminary Prospectus
      did, and the Registration Statement and the Prospectus and any amendments
      or supplements thereto, when they become effective or are filed with the
      Commission, as the case may be, will conform in all material respects to
      the requirements of the Act, the Exchange Act and the respective rules and
      regulations of the Commission thereunder 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 the
      light of the circumstances under which they are made, not misleading. Such
      Selling Securityholder has reviewed the Prospectus (or, if the Prospectus
      is not in existence, the most recent Preliminary Prospectus) and the
      Registration Statement, and the information regarding such Selling
      Securityholder set forth therein under the caption "Principal and Selling
      Securityholders" is complete and accurate.

          (f) The sale by such Selling Securityholder of Securities pursuant
      hereto is not prompted by any material adverse information concerning the
      Company that is not set forth in the Registration Statement or the
      Prospectus (or, if the Prospectus is not in existence, the most recent
      Preliminary Prospectus).

          (g) The sale of the Securities to the Underwriters by such Selling
      Securityholder pursuant to this Agreement, the compliance by such Selling
      Securityholder with the other provisions of this Agreement, the Custody
      Agreement and the consummation of the other transactions herein
      contemplated do not (i) require the consent, approval, authorization,
      registration or qualification of or with any governmental authority,
      except such as have been obtained, such as may be required under state
      securities or blue sky laws or the rules and


                                      -10-
<PAGE>   11


      regulations of the NASD and, if the registration statement filed with
      respect to the Securities (as amended) is not effective under the Act as
      of the time of execution hereof, such as may be required (and shall be
      obtained as provided in this Agreement) under the Act and the Exchange
      Act, or (ii) conflict with or result in a breach or violation of any of
      the terms and provisions of, or constitute a default under any indenture,
      mortgage, deed of trust, lease or other agreement or instrument to which
      such Selling Securityholder is a party or by which such Selling
      Securityholder or any of such Selling Securityholder's properties are
      bound, or any statute or any judgment, decree, order, rule or regulation
      of any court or other governmental authority or any arbitrator applicable
      to such Selling Securityholder, except any conflict, breach, violation or
      default which would not result in a material adverse affect with respect
      to the ability of the Selling Securityholder to perform its obligations
      under this Agreement.

          (h) Phillip M. Drayer (the "Officer Selling Securityholder")
      represents and warrants to, and agrees with, each of the several
      Underwriters that (i) the Registration Statement when it became effective
      did not contain any untrue statement of a material fact or omit to state a
      material fact required to be stated therein or necessary to make the
      statements therein not misleading, and (ii) the Prospectus does not
      contain any untrue statement of a material fact or omit to state a
      material fact necessary to make the statements therein, in light of the
      circumstances under which they were made, not misleading, except that the
      representations and warranties in this Section 3(h) do not apply to
      statements or omissions in the Registration Statement or the Prospectus
      based upon (x) information relating to any Underwriter furnished to the
      Company in writing by such Underwriter through you for use therein or (y)
      information relating to any other Selling Security holder furnished by or
      on behalf of such Selling Securityholder for use therein.

          4. Purchase, Sale and Delivery of the Securities. (a) On the basis of
      the representations, warranties, agreements and covenants herein contained
      and subject to the terms and conditions herein set forth, the Company and
      the Selling Securityholders, severally and not jointly, agree to issue and
      sell to each of the Underwriters, and each of the Underwriters, severally
      and not jointly, agrees to purchase from the Company and the Selling
      Securityholders, at a purchase price of $_______ per share, the number of
      Firm Securities set forth opposite the name of such Underwriter in
      Schedule 1 hereto. One or more certificates in definitive form for the
      Firm Securities that the several Underwriters have agreed to purchase
      hereunder, and in such denomination or denominations and registered in
      such name or names as the Representatives request upon notice to the
      Company and Selling Securityholders at least 48 hours prior to the Firm
      Closing Date, shall be delivered by or on behalf of the Company and
      Selling Securityholders to the Representatives for the respective accounts
      of the Underwriters, against payment by or on behalf of the Underwriters
      of the purchase price therefor by wire transfer in same-day funds (the
      "Wired Funds") to the account of the Company and the Selling
      Securityholders. Such delivery of and payment for the Firm Securities
      shall be made at the offices of Wilson Sonsini Goodrich and Rosati, P.C.,
      650 Page Mill Road, Palo Alto, California at 9:30 A.M., New York time, on
      March , 2000, or at such other place, time or date as the Representatives
      and the Company may agree upon or as the Representatives may determine
      pursuant to Section 11 hereof, such time and date of delivery against
      payment being herein referred to as the "Firm Closing Date". The Company
      and Selling Securityholders will make such certificate or certificates for
      the Firm Securities available for checking and packaging by the
      Representatives at the offices in New York, New York of the Company's
      transfer agent or registrar or of Prudential Securities Incorporated at
      least 24 hours prior to the Firm Closing Date.

          (b) For the purpose of covering any over-allotments in connection with
      the distribution and sale of the Firm Securities as contemplated by the
      Prospectus, the Company hereby grants to the

                                      -11-
<PAGE>   12

      several Underwriters an option to purchase, severally and not jointly,
      378,500 Option Securities and each Selling Securityholder hereby grants to
      the several Underwriters an option to purchase, severally and not jointly,
      the number of Option Securities set forth opposite such Selling
      Securityholder's name on Schedule 2 hereto. The purchase price to be paid
      for any Option Securities shall be the same price per share as the price
      per share for the Firm Securities set forth above in paragraph (a) of this
      Section 4. The option granted hereby may be exercised as to all or any
      part of the Option Securities from time to time within thirty days after
      the date of the Prospectus (or, if such 30th day shall be a Saturday or
      Sunday or a holiday, on the next business day thereafter when the New York
      Stock Exchange is open for trading). In the event such option is exercised
      with respect to less than 478,500 Option Securities, the Officer Selling
      Securityholder will sell the first 100,000 Option Securities and the
      Company will sell the remaining Option Securities to be sold. The
      Underwriters shall not be under any obligation to purchase any of the
      Option Securities prior to the exercise of such option. The
      Representatives may from time to time exercise the option granted hereby
      by giving notice in writing or by telephone (confirmed in writing) to the
      Company and the Selling Securityholders setting forth the aggregate amount
      of Option Securities as to which the several Underwriters are then
      exercising the option and the date and time for delivery of and payment
      for such Option Securities. Any such date of delivery shall be determined
      by the Representatives but shall not be earlier than two business days or
      later than five business days after such exercise of the option and, in
      any event, shall not be earlier than the Firm Closing Date. The time and
      date set forth in such notice, or such other time on such other date as
      the Representatives, the Selling Securityholders and the Company may agree
      upon or as the Representatives may determine pursuant to Section 11
      hereof, is herein called the "Option Closing Date" with respect to such
      Option Securities. Upon exercise of the option as provided herein, the
      Company and each Selling Securityholder shall become obligated to sell to
      each of the several Underwriters, and, subject to the terms and conditions
      herein set forth, each of the Underwriters (severally and not jointly)
      shall become obligated to purchase from the Company and each Selling
      Securityholder, the same percentage of the total number of the Option
      Securities as to which the several Underwriters are then exercising the
      option as such Underwriter is obligated to purchase of the aggregate
      number of Firm Securities, as adjusted by the Representatives in such
      manner as they deem advisable to avoid fractional shares. If the option is
      exercised as to all or any portion of the Option Securities, one or more
      certificates in definitive form for such Option Securities, and payment
      therefor, shall be delivered by and to the Company and the Selling
      Securityholders on the related Option Closing Date in the manner, and upon
      the terms and conditions, set forth in paragraph (a) of this Section 4,
      except that reference therein to the Firm Securities and the Firm Closing
      Date shall be deemed, for purposes of this paragraph (b), to refer to such
      Option Securities and Option Closing Date, respectively.

        (c) The Company and the Selling Securityholders hereby acknowledge that
      the wire transfer by or on behalf of the Underwriters of the purchase
      price for any Securities does not constitute closing of a purchase and
      sale of the Securities. Only execution and delivery of a receipt for
      Securities by the Underwriters indicates completion of the closing of a
      purchase of the Securities from the Company or the Selling
      Securityholders. Furthermore, in the event that the Underwriters wire
      funds to the Company or the Selling Securityholders prior to the
      completion of the closing of a purchase of Securities, the Company and the
      Selling Securityholders hereby acknowledge that until the Underwriters
      execute and deliver a receipt for the Securities, by facsimile or
      otherwise, the Company and the Selling Securityholders will not be
      entitled to the Wired Funds and shall return the Wired Funds to the
      Underwriters as soon as practicable (by wire transfer of same-day funds)
      upon demand. In the event that the closing of a purchase of Securities is
      not completed and the Wired Funds are not returned by the Company or the
      Selling Securityholders to the Underwriters on the same day the Wired
      Funds were received by the Company or the Selling Securityholders, the
      Company, or the Selling Securityholder who received


                                      -12-
<PAGE>   13

      such Wired Funds, as applicable, agrees to pay to the Underwriters in
      respect of each day the Wired Funds are not returned by it, in same-day
      funds, interest on the amount of such Wired Funds in an amount
      representing the Underwriters' cost of financing as reasonably determined
      by Prudential Securities Incorporated.

          (d) It is understood that any of you, individually and not as one of
      the Representatives, may (but shall not be obligated to) make payment on
      behalf of any Underwriter or Underwriters for any of the Securities to be
      purchased by such Underwriter or Underwriters. No such payment shall
      relieve such Underwriter or Underwriters from any of its or their
      obligations hereunder.

          5. Offering by the Underwriters. Upon your authorization of the
      release of the Firm Securities, the several Underwriters propose to offer
      the Firm Securities for sale to the public upon the terms set forth in the
      Prospectus.

          6. Covenants of the Company. The Company covenants and agrees with
      each of the Underwriters that:

          (a) The Company will use its best efforts to cause the Registration
      Statement, if not effective at the time of execution of this Agreement,
      and any amendments thereto to become effective as promptly as possible. If
      required, the Company will file the Prospectus or any Term Sheet that
      constitutes a part thereof and any amendment or supplement thereto with
      the Commission in the manner and within the time period required by Rule
      434 and 424(b) under the Act. During any time when a prospectus relating
      to the Securities is required to be delivered under the Act, the Company
      (i) will comply with all requirements imposed upon it by the Act and the
      Exchange Act and the respective rules and regulations of the Commission
      thereunder to the extent necessary to permit the continuance of sales of
      or dealings in the Securities in accordance with the provisions hereof and
      each of the Prospectus and any Integrated Prospectus, as then amended or
      supplemented, and (ii) will not file with the Commission the prospectus or
      the amendment referred to in the third sentence of Section 2(a) hereof,
      any amendment or supplement to such prospectus or any amendment to the
      Registration Statement or any Rule 462(b) Registration Statement of which
      the Representatives shall not previously have been advised and furnished
      with a copy for a reasonable period of time prior to the proposed filing
      and as to which filing the Representatives shall not have given their
      consent. The Company will prepare and file with the Commission, in
      accordance with the rules and regulations of the Commission, promptly upon
      request by the Representatives or counsel for the Underwriters, any
      amendments to the Registration Statement or amendments or supplements to
      the Prospectus and any Integrated Prospectus that may be necessary or
      advisable in connection with the distribution of the Securities by the
      several Underwriters, and will use its best efforts to cause any such
      amendment to the Registration Statement to be declared effective by the
      Commission as promptly as possible. The Company will advise the
      Representatives, promptly after receiving notice thereof, of the time when
      the Registration Statement or any amendment thereto has been filed or
      declared effective or the Prospectus and any Integrated Prospectus or any
      amendment or supplement thereto has been filed and will provide evidence
      reasonably satisfactory to the Representatives of each such filing or
      effectiveness.

             (b) The Company will advise the Representatives, promptly after
      receiving notice or obtaining knowledge thereof, of (i) the issuance by
      the Commission of any stop order suspending the effectiveness of the
      Original Registration Statement or any Rule 462(b) Registration Statement
      or any post-effective amendment thereto or any order directed at any
      document incorporated by reference in the Registration Statement or the
      Prospectus and any required Integrated Prospectus are or any amendment or
      supplement thereto or any order preventing or


                                      -13-
<PAGE>   14

      suspending the use of any Preliminary Prospectus, the Prospectus and
      any Integrated Prospectus or any amendment or supplement thereto, (ii) the
      suspension of the qualification of the Securities for offering or sale in
      any jurisdiction, (iii) the institution, threatening or contemplation of
      any proceeding for any such purpose or (iv) any request made by the
      Commission for amending the Original Registration Statement or any Rule
      462(b) Registration Statement, for amending or supplementing any
      Preliminary Prospectus, the Prospectus and any Integrated Prospectus or
      for additional information. The Company will use its best efforts to
      prevent the issuance of any such stop order and, if any such stop order is
      issued, to obtain the withdrawal thereof as promptly as possible.

          (c) The Company will arrange for the qualification of the Securities
      for offering and sale under the securities or blue sky laws of such
      jurisdictions as the Representatives may designate and will continue such
      qualifications in effect for as long as may be necessary to complete the
      distribution of the Securities, provided, however, that in connection
      therewith the Company shall not be required to qualify as a foreign
      corporation or to execute a general consent to service of process in any
      jurisdiction.

          (d) If, at any time prior to the later of (i) the final date when a
      prospectus relating to the Securities is required to be delivered under
      the Act or (ii) the Option Closing Date, any event occurs as a result of
      which the Prospectus, as then amended or supplemented, would include 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, or if for any
      other reason it is necessary at any time to amend or supplement the
      Prospectus to comply with the Act, the Exchange Act or the respective
      rules or regulations of the Commission thereunder, the Company will
      promptly notify the Representatives thereof and, subject to Section 6(a)
      hereof, will prepare and file with the Commission, at the Company's
      expense, an amendment to the Registration Statement, an amendment or
      supplement to the Prospectus or any Integrated Prospectus that corrects
      such statement or omission or effects such compliance.

          (e) The Company will, without charge, provide (i) to the
      Representatives and to counsel for the Underwriters a conformed copy of
      the registration statement originally filed with respect to the Securities

      incident to (i) the printing or other production of documents with respect
      to the transactions, including any costs of printing the registration

      Prospectus, the Prospectus and any Integrated Prospectus and any amendment

          Company's subsidiaries or with respect to any of their respective

          therein but not including the financial statements and related notes
          and schedules and other financial data contained therein, as to which
          such counsel need express no opinion) comply as to form in all

          is not "materially different", as such term is used in Rule 434, from
          the prospectus included in the Registration Statement at the time of
          its effectiveness or any effective post-effective amendment thereto
          (including such information that is permitted to be omitted pursuant
          to Rule 430A).

                 (xi) this Agreement, the Custody Agreement and the Power of
          Attorney have been duly executed and delivered by each Selling
          Securityholder; assuming due authorization, execution and delivery by
          the Custodian, the Custody Agreement and the Power of Attorney are the

          Securityholder, subject to applicable bankruptcy, insolvency and
          similar laws affecting creditors' rights generally and subject, as to

                 (xii) upon delivery of and payment for the Securities to be
          sold by each Selling Securityholder as contemplated by this Agreement,
          the Underwriters will be "protected purchasers" within the meaning of

          interests therein free of any "adverse claim" within the meaning of
          Division 8 of the Uniform Commercial Code, provided that the
          Underwriters are purchasing such Securities in good faith and without
          notice of any such adverse claim;

                 (xiii) the sale of the Securities to the Underwriters by such
          Selling Securityholder pursuant to this Agreement, the compliance by
          such Selling Securityholder with the other provisions of this
          Agreement, the Custody Agreement and the consummation of the other
          transactions herein contemplated do not (i) require the consent,
          approval, authorization, registration or qualification of or with any
          governmental authority, except such as have been obtained and such as
          may be required under state securities or blue sky laws or the rules
          and regulations of the NASD, or (ii) conflict with or result in a
          breach or violation of any of the terms and provisions of, or
          constitute a default under any indenture, mortgage, deed of trust,
          lease or other agreement or instrument to which such Selling
          Securityholder is a party or by which such Selling Securityholder or
          any of such Selling Securityholder's properties are bound, or, to our
          knowledge, any statute or any judgment, decree,


                                      -19-

             order, rule or regulation of any court or other governmental
             authority or any arbitrator applicable to such Selling
             Securityholder, except any conflict, breach, violation or default
             which would not result in a material adverse affect with respect to
             the ability of the Selling Securityholder to perform its
             obligations under this Agreement.

      Such counsel shall also state that they have no reason to believe that the
      Registration Statement, as of its effective date, contained any untrue
      statement of a material fact or omitted to state any material fact
      required to be stated therein or necessary to make the statements therein
      not misleading or that the Prospectus and any Integrated Prospectus, as of
      its date or the date of such opinion, included or includes 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 the light of the
      circumstances under which they were made, not misleading.

             In rendering any such opinion, such counsel may rely, as to matters
      of fact, to the extent such counsel deems proper, on certificates of
      responsible officers of the Company, on the representations and warranties
      of the Selling Securityholders contained herein and in the Power of
      Attorney and Custody Agreement, and public officials.

             References to the Registration Statement and the Prospectus and any
      Integrated Prospectus in this paragraph (b) shall include any amendment or
      supplement thereto at the date of such opinion.

            laws of all other jurisdictions where the ownership or leasing of
            its properties or the conduct of its business requires such
            qualification, except where the failure to be so qualified does not
            amount to a material liability or disability to the Company and its
            subsidiaries, taken as a whole;

               (ii) The Hong Kong Subsidiary has corporate power to own or lease
            its properties and conduct its business as described in the
            Registration Statement and the Prospectus or any Integrated

            knowledge of such counsel, any other security interests, liens,

             (v) the issuance, offering and sale of the Securities to the
            Underwriters by the Company pursuant to this Agreement, the
            compliance by the Company with the other provisions of this
            Agreement and the consummation of the other transactions herein
            contemplated do not conflict with or result in a breach or violation
            of any of the terms and provisions of, or constitute a default
            under, any indenture, mortgage, deed of trust, lease or other
            agreement or instrument known to such counsel to which the Hong Kong
            Subsidiary is a party or by which the Hong Kong Subsidiary or any of
            its properties are bound, or the charter documents or by-laws of the
            Hong Kong Subsidiary, or any statute or any judgment, decree, order,
            rule or regulation of any court or other governmental authority or
            any arbitrator known to such counsel and applicable to the Hong Kong
            Subsidiary.

             In rendering any such opinion, such counsel may rely, as to matters
      of fact, to the extent such counsel deems proper, on certificates of
      responsible officers of the Company and public officials.

             References to the Registration Statement and the Prospectus and any
      Integrated Prospectus in this paragraph (c) shall include any amendment or
      supplement thereto at the date of such opinion.

             (d) The Representatives shall have received an opinion, dated the
      Firm Closing Date, of Pillsbury Madison & Sutro LLP, counsel for the
      Underwriters, with respect to the issuance and sale of the Firm
      Securities, the Registration Statement, the Prospectus or any Integrated
      Prospectus, and such other related matters as the Representatives may
      reasonably require, and the Company shall have furnished to such counsel
      such documents as they may reasonably request for the purpose of enabling
      them to pass upon such matters.

             (e) The Representatives shall have received from
      PricewaterhouseCoopers LLP a letter or letters dated, respectively, the
      date hereof and the Firm Closing Date, in form and substance satisfactory
      to the Representatives, to the effect that:

               (i) they are independent accountants with respect to the Company
            and its consolidated subsidiaries within the meaning of the Act, the
            Exchange Act and the applicable rules and regulations thereunder;

               (ii) in their opinion, the audited consolidated financial
            statements and schedules examined by them and included in the
            Registration Statement, the Prospectus and any Integrated Prospectus
            comply in form in all material respects with the applicable
            accounting requirements of the Act, the Exchange Act and the related
            published rules and regulations thereunder;

               (iii) on the basis of a reading of the latest available interim
            unaudited consolidated condensed financial statements of the Company
            and its consolidated subsidiaries, carrying out certain specified
            procedures (which do not constitute an examination made in
            accordance with generally accepted auditing standards) that would
            not necessarily reveal matters of significance with respect to the
            comments set forth in this paragraph (iii), a reading of the minute
            books of the shareholders, the board of directors and any committees
            thereof of the Company and each of its consolidated subsidiaries,
            and inquiries of certain officials of the Company and its
            consolidated subsidiaries who have responsibility for financial and
            accounting

            matters, nothing came to their attention that caused them to
            believe that: at March __, 2000, there were any changes in the
            capital stock or long-term debt of the Company and its consolidated
            subsidiaries or any decreases in net current assets or stockholders'
            equity of the Company and its consolidated subsidiaries, in each
            case compared with amounts shown on the December 31, 1999 audited
            balance sheet included in the Registration Statement, the Prospectus
            and any Integrated Prospectus, or for the period from January 1,
            2000 to such specified date there were any decreases, as compared
            with amounts shown on the December 31, 1999 audited statement of
            income included in the Registration Statement, in sales, net
            revenues, net income before income taxes or total or per share
            amounts of net income of the Company and its consolidated
            subsidiaries, except in all instances for changes, decreases or
            increases set forth in such letter;

               (iv) they have carried out certain specified procedures, not
            constituting an audit, with respect to certain amounts, percentages
            and financial information that are derived from the general
            accounting records of the Company and its consolidated subsidiaries
            and are included in the Registration Statement, the Prospectus and
            any Integrated Prospectus or under any Exchange Act reports
            incorporated by reference in the Registration Statement, the
            Prospectus and any Integrated Prospectus, and have compared such
            amounts, percentages and financial information with such records of
            the Company and its consolidated subsidiaries and with information
            derived from such records and have found them to be in agreement,
            excluding any questions of legal interpretation.

             In the event that the letters referred to above set forth any such
      changes, decreases or increases, it shall be a further condition to the
      obligations of the Underwriters that (A) such letters shall be accompanied
      by a written explanation of the Company as to the significance thereof,
      unless the Representatives deem such explanation unnecessary, and (B) such
      changes, decreases or increases do not, in the sole judgment of the
      Representatives, make it impractical or inadvisable to proceed with the
      purchase and delivery of the Securities as contemplated by the
      Registration Statement, as amended as of the date hereof.

             References to the Registration Statement, the Prospectus and any
      Integrated Prospectus in this paragraph (e) with respect to either letter
      referred to above shall include any amendment or supplement thereto at the
      date of such letter.

            Agreement are true and correct as if made on and as of the Firm

            statements therein not misleading; the Prospectus and any Integrated
            Prospectus, as amended or supplemented as of the Firm Closing Date,
            does not include any untrue statement of a material fact or omit to
            state any material fact necessary in order to make the statements
            therein, in the light of the circumstances under which they were
            made, not misleading; and the Company has performed all covenants
            and agreements and satisfied all conditions on its part to be
            performed or satisfied at or prior to the Firm Closing Date;

               (ii) no stop order suspending the effectiveness of the
            Registration Statement or any post-effective amendment thereto and

            purpose have been instituted or, to the Company's knowledge,
            threatened or are contemplated by the Commission; and

               (iii) subsequent to the respective dates as of which information
            is given in the Registration Statement, the Prospectus and any
            Integrated Prospectus, neither the Company nor any of its
            Subsidiaries has sustained any material loss or interference with
            their respective businesses or properties from fire, flood,
            hurricane, accident or other calamity, whether or not covered by
            insurance, or from any labor dispute or any legal or governmental
            proceeding, and there has not been any material adverse change, or
            any development involving a prospective material adverse change, in
            the condition (financial or otherwise), management, business,
            prospects, net worth or results of operations of the Company or any
            of its subsidiaries, taken as a whole, except in each case as
            described in or contemplated by the Prospectus and any Integrated
            Prospectus.

        (g) The Representatives shall have received from each person who is a

             The respective obligations of the several Underwriters to purchase

             10.    Indemnification and Contribution.

             (a) The Company agrees to indemnify and hold harmless each
      Underwriter and each person, if any, who controls any Underwriter within
      the meaning of Section 15 of the Act or Section 20 of the Exchange Act
      against any losses, claims, damages or liabilities, joint or several, to
      which such Underwriter or such controlling person may become subject under
      the Act, the Exchange Act or otherwise, insofar as such losses, claims,
      damages or liabilities (or actions in respect thereof) arise out of or are
      based upon:

                 (i) any untrue statement or alleged untrue statement made by
            the Company in Section 2 of this Agreement,

                 (ii) any untrue statement or alleged untrue statement of any
            material fact contained in (A) the Registration Statement or any
            amendment thereto, any Preliminary Prospectus, the Prospectus and
            any Integrated Prospectus or any amendment or supplement thereto or
            (B) any application or other document, or any amendment or
            supplement thereto, executed by the Company or based upon written
            information furnished by or on behalf of the Company filed in any
            jurisdiction in order to qualify the Securities under the securities
            or blue sky laws thereof or filed with the Commission or any
            securities association or securities exchange (each an
            "Application"),

                 (iii) the omission or alleged omission to state in the
            Registration Statement or any amendment thereto, any Preliminary
            Prospectus, the Prospectus and any Integrated Prospectus or any
            amendment or supplement thereto, or any Application, a material fact
            required to be stated therein or necessary to make the statements
            therein not misleading, or

                 (iv) any untrue statement or alleged untrue statement of any
            material fact contained in any audio or visual materials provided by
            the Company or based upon written information furnished by or on
            behalf of the Company, including without limitation, slides, videos,
            films and tape recordings, used in connection with the marketing of
            the Securities, including, without limitation, statements
            communicated to securities analysts employed by the Underwriters;

            and will reimburse, as incurred, each Underwriter and each such
            controlling person for any legal or other expenses reasonably
            incurred by such Underwriter or such controlling person in
            connection with investigating, defending against or appearing as a
            third-party witness in connection with any such loss, claim, damage,
            liability or action; provided, however, that the Company will not


                                      -24-
<PAGE>   25

            be liable in any such case to the extent that any such loss, claim,
            damage or liability arises out of or is based upon any untrue
            statement or alleged untrue statement or omission or alleged
            omission made in such registration statement or any amendment
            thereto, any Preliminary Prospectus, the Prospectus and any
            Integrated Prospectus or any amendment or supplement thereto, or any
            Application in reliance upon and in conformity with written
            information furnished to the Company by such Underwriter through the
            Representatives specifically for use therein; and provided, further,
            that the Company will not be liable to any Underwriter or any person
            controlling such Underwriter with respect to any such untrue
            statement or omission made in any Preliminary Prospectus that is
            corrected in the Prospectus (or any amendment or supplement thereto)
            if the person asserting any such loss, claim, damage or liability
            purchased Securities from such Underwriter but was not sent or given
            a copy of the Prospectus (as amended or supplemented), other than
            the documents incorporated by reference therein, at or prior to the
            written confirmation of the sale of such Securities to such person
            in any case where such delivery of the Prospectus (as amended or
            supplemented) is required by the Act, unless such failure to deliver
            the Prospectus (as amended or supplemented) was a result of
            noncompliance by the Company with Section 6(d) or (a) of this
            Agreement. This indemnity agreement will be in addition to any
            liability which the Company may otherwise have. The Company will
            not, without the prior written consent of the Underwriter or
            Underwriters purchasing, in the aggregate, more than fifty percent
            (50%) of the Securities, settle or compromise or consent to the
            entry of any judgment in any pending or threatened claim, action,
            suit or proceeding in respect of which indemnification may be sought
            hereunder (whether or not any such Underwriter or any person who
            controls any such Underwriter within the meaning of Section 15 of
            the Act or Section 20 of the Exchange Act is a party to such claim,
            action, suit or proceeding), unless such settlement, compromise or
            consent includes an unconditional release of all of the Underwriters
            and such controlling persons from all liability arising out of such
            claim, action, suit or proceeding.

             (b) Each Selling Securityholder, severally and not jointly, agrees
      to indemnify and hold harmless each Underwriter and each person, if any,
      who controls any Underwriter within the meaning of Section 15 of the Act
      or Section 20 of the Exchange Act against any losses, claims, damages or
      liabilities, joint or several, to which such Underwriter or such
      controlling person may become subject under the Act, the Exchange Act or
      otherwise, insofar as such losses, claims, damages or liabilities (or
      actions in respect thereof) arise out of or are based upon:

                (i) any untrue statement or alleged untrue statement of any
            material fact contained in the Registration Statement or any
            amendment thereto, any Preliminary Prospectus, the Prospectus and
            any Integrated Prospectus or any amendment or supplement thereto or
            any Application or the omission or alleged omission to state therein
            a material fact required to be stated in the Registration Statement
            or any amendment thereto, any Preliminary Prospectus, the Prospectus
            or any amendment or supplement thereto, or any Application or
            necessary to make the statements therein not misleading , in each
            case to the extent, but only to the extent, that such untrue
            statement or alleged untrue statement or omission or alleged
            omission was made in reliance upon and in conformity with written
            information furnished to the Company by such Selling Securityholder
            specifically for use therein;

                (ii) In addition to (b)(i) above, with respect to the Officer
            Selling Securityholder only, any untrue statement or alleged untrue
            statement made by such Officer Selling Securityholder in Section
            3(h) of this Agreement,

      and, subject to the limitations set forth immediately preceding this
      clause, will reimburse, as incurred, each Underwriter and such controlling
      person for any legal or other expenses reasonably incurred by such
      Underwriter or such controlling person in connection with investigation,
      defending against or appearing as a third-party witness in connection with
      any such loss, claim, damage, liability or action; provided, however, that
      the Selling Securityholder will not be liable in any such case to the
      extent that any such loss, claim, damage or liability arises out of or is
      based upon any untrue statement or alleged untrue statement or omission or
      alleged


                                      -25-
<PAGE>   26


      omission made in such Registration Statement or any amendment
      thereto, any Preliminary Prospectus, the Prospectus and any Integrated
      Prospectus or any amendment or supplement thereto, or any Application in
      reliance upon and in conformity with written information furnished to the
      Company by any other Selling Securityholder or by such Underwriter
      specifically for use therein; and provided, further, that the Selling
      Securityholder will not be liable to any Underwriter or any person
      controlling such Underwriter with respect to any such untrue statement or
      omission made in any Preliminary Prospectus that is corrected in the
      Prospectus (or any amendment or supplement thereto) if the person
      asserting any such loss, claim, damage or liability purchased Securities
      from such Underwriter but was not sent or given a copy of the Prospectus
      (as amended or supplemented), other than the documents incorporated by
      reference therein, at or prior to the written confirmation of the sale of
      such Securities to such person in any case where such delivery of the
      Prospectus (as amended or supplemented) is required by the Act.

             (c) Each Underwriter, severally and not jointly, will indemnify and
      hold harmless the Company, each of its directors, each of its officers who
      signed the Registration Statement, each Selling Securityholder, and each
      person, if any, who controls the Company or such Selling Securityholder
      within the meaning of Section 15 of the Act or Section 20 of the Exchange
      Act against any losses, claims, damages or liabilities to which the
      Company, any director or officer of the Company, such Selling
      Securityholder or any such controlling person of the Company or such
      Selling Securityholder may become subject under the Act, the Exchange Act
      or otherwise, insofar as such losses, claims, damages or liabilities (or
      actions in respect thereof) arise out of or are based upon (i) any untrue
      statement or alleged untrue statement of any material fact contained in
      the Registration Statement or any amendment thereto, any Preliminary
      Prospectus, the Prospectus or any Integrated Prospectus or any amendment
      or supplement thereto, or any Application or (ii) the omission or the
      alleged omission to state therein a material fact required to be stated in
      the Registration Statement or any amendment thereto, any Preliminary
      Prospectus, the Prospectus or any amendment or supplement thereto, or any
      Application or necessary to make the statements therein not misleading, in
      each case to the extent, but only to the extent, that such untrue
      statement or alleged untrue statement or omission or alleged omission was
      made in reliance upon and in conformity with written information furnished
      to the Company by such Underwriter through the Representatives
      specifically for use therein; and, subject to the limitation set forth
      immediately preceding this clause, will reimburse, as incurred, any legal
      or other expenses reasonably incurred by the Company or any such director,
      officer or controlling person or such Selling Securityholder in connection
      with investigating or defending any such loss, claim, damage, liability or
      any action in respect thereof. This indemnity agreement will be in
      addition to any liability which such Underwriter may otherwise have.

             (d) Promptly after receipt by an indemnified party under this
      Section 10 of notice of the commencement of any action, such indemnified
      party will, if a claim in respect thereof is to be made against the
      indemnifying party under this Section 10, notify the indemnifying party of
      the commencement thereof; but the omission so to notify the indemnifying
      party will not relieve it from any liability which it may have to any
      indemnified party otherwise than under this Section 10, except to the
      extent the indemnifying party is prejudiced thereby. In case any such
      action is brought against any indemnified party, and it notifies the
      indemnifying party of the commencement thereof, the indemnifying party
      will be entitled to participate therein and, to the extent that it may
      wish, jointly with any other indemnifying party similarly notified, to
      assume the defense thereof, with counsel reasonably satisfactory to such
      indemnified party; provided, however, that if the defendants in any such
      action include both the indemnified party and the indemnifying party and
      the indemnified party shall have reasonably concluded that there may be
      one or more legal defenses available to it and/or other indemnified
      parties which are different from or additional to those available to the
      indemnifying party, the indemnifying party shall not have the right to
      direct


                                      -26-
<PAGE>   27

      the defense of such action on behalf of such indemnified party or parties
      and such indemnified party or parties shall have the right to select
      separate counsel to defend such action on behalf of such indemnified party
      or parties. After notice from the indemnifying party to such indemnified
      party of its election so to assume the defense thereof and approval by
      such indemnified party of counsel appointed to defend such action, the
      indemnifying party will not be liable to such indemnified party under this
      Section 10 for any legal or other expenses, other than reasonable costs of
      investigation, subsequently incurred by such indemnified party in
      connection with the defense thereof, unless (i) the indemnified party
      shall have employed separate counsel in accordance with the proviso to the
      next preceding sentence (it being understood, however, that in connection
      with such action the indemnifying party shall not be liable for the
      expenses of more than one separate counsel (in addition to local counsel)
      in any one action or separate but substantially similar actions arising
      out of the same general allegations or circumstances, designated by the
      Representatives in the case of paragraph (a) of this Section 10,
      representing the indemnified parties under such paragraph (a) who are
      parties to such action or actions) or (ii) the indemnifying party does not
      promptly retain counsel reasonably satisfactory to the indemnified party
      or (iii) the indemnifying party has authorized the employment of counsel
      for the indemnified party at the expense of the indemnifying party. After
      such notice from the indemnifying party to such indemnified party, the
      indemnifying party will not be liable for the costs and expenses of any
      settlement of such action effected by such indemnified party without the
      consent of the indemnifying party.

             (e) In circumstances in which the indemnity agreement provided for
      in the preceding paragraphs of this Section 10 is unavailable or
      insufficient, for any reason, to hold harmless an indemnified party in
      respect of any losses, claims, damages or liabilities (or actions in
      respect thereof), each indemnifying party, in order to provide for just
      and equitable contribution, shall contribute to the amount paid or payable
      by such indemnified party as a result of such losses, claims, damages or
      liabilities (or actions in respect thereof) in such proportion as is
      appropriate to reflect (i) the relative benefits received by the
      indemnifying party or parties on the one hand and the indemnified party on
      the other from the offering of the Securities or (ii) if the allocation
      provided by the foregoing clause (i) is not permitted by applicable law,
      not only such relative benefits but also the relative fault of the
      indemnifying party or parties on the one hand and the indemnified party on
      the other in connection with the statements or omissions or alleged
      statements or omissions that resulted in such losses, claims, damages or
      liabilities (or actions in respect thereof), as well as any other relevant
      equitable considerations. The relative benefits received by the Company
      and the Selling Securityholders on the one hand and the Underwriters on
      the other shall be deemed to be in the same proportion as the total
      proceeds from the offering (before deducting expenses) received by the
      Company and the Selling Securityholders bear to the total underwriting
      discounts and commissions received by the Underwriters. The relative fault
      of the parties shall be determined by reference to, among other things,
      whether the untrue or alleged untrue statement of a material fact or the
      omission or alleged omission to state a material fact relates to
      information supplied by the Company, the Selling Securityholders or the
      Underwriters, the parties' relative intents, knowledge, access to
      information and opportunity to correct or prevent such statement or
      omission, and any other equitable considerations appropriate in the
      circumstances. The Company and the Underwriters agree that it would not be
      equitable if the amount of such contribution were determined by pro rata
      or per capita allocation (even if the Underwriters were treated as one
      entity for such purpose) or by any other method of allocation that does
      not take into account the equitable considerations referred to above in
      this paragraph (e). Notwithstanding any other provision of this paragraph
      (e), no Underwriter shall be obligated to make contributions hereunder
      that in the aggregate exceed the total public offering price of the
      Securities purchased by such Underwriter under this Agreement, less the
      aggregate amount of any damages that such Underwriter has otherwise been
      required to pay in respect of the same or



                                      -27-
<PAGE>   28

      any substantially similar claim, and no person guilty of fraudulent
      misrepresentation (within the meaning of Section 11(f) of the Act) shall
      be entitled to contribution from any person who was not guilty of such
      fraudulent misrepresentation. The Underwriters' obligations to contribute
      hereunder are several in proportion to their respective underwriting
      obligations and not joint, and contributions among Underwriters shall be
      governed by the provisions of the Prudential Securities Incorporated
      Master Agreement Among Underwriters. For purposes of this paragraph (e),
      each person, if any, who controls an Underwriter within the meaning of
      Section 15 of the Act or Section 20 of the Exchange Act shall have the
      same rights to contribution as such Underwriter, and each director of the
      Company, each officer of the Company who signed the Registration Statement
      and each person, if any, who controls the Company or any Selling
      Securityholders within the meaning of Section 15 of the Act or Section 20
      of the Exchange Act, shall have the same rights to contribution as the
      Company or such Selling Securityholder, as the case may be.

             (f) Notwithstanding any other provision herein, the liability of
      each Selling Securityholder hereunder shall not exceed an amount equal to
      the purchase price per share set forth in Section 4 hereof multiplied by
      the number of Securities sold by such Selling Securityholder.

             (g) The Company and each of the Underwriters agree with the Officer
      Selling Securityholder that any claim of such Underwriters against such
      Officer Selling Securityholder for indemnification, contribution,
      reimbursement or advancement of expenses or breach of any representation
      or warranty herein (other than with respect to the representations and
      warranties in Sections 3(a) through 3(e) and Section 3(g) hereof) shall
      first be sought by such Underwriter to be satisfied in full by the Company
      and, subject to the limitation on the aggregate liability of the Officer
      Selling Securityholder set forth in Section 10(f), shall be satisfied by
      the Officer Selling Securityholder only to the extent that such claim has
      not been satisfied by the Company within the sixty (60) day period
      following the date requested for payment in accordance with the terms of
      this Agreement.

             11. Default of Underwriters. If one or more Underwriters default in
      their obligations to purchase Firm Securities or Option Securities
      hereunder and the aggregate number of such Securities that such defaulting
      Underwriter or Underwriters agreed but failed to purchase is ten percent
      or less of the aggregate number of Firm Securities or Option Securities to
      be purchased by all of the Underwriters at such time hereunder, the other
      Underwriters may make arrangements satisfactory to the Representatives for
      the purchase of such Securities by other persons (who may include one or
      more of the non-defaulting Underwriters, including the Representatives),
      but if no such arrangements are made by the Firm Closing Date or the
      related Option Closing Date, as the case may be, the other Underwriters
      shall be obligated severally in proportion to their respective commitments
      hereunder to purchase the Firm Securities or Option Securities that such
      defaulting Underwriter or Underwriters agreed but failed to purchase. If
      one or more Underwriters so default with respect to an aggregate number of
      Securities that is more than ten percent of the aggregate number of Firm
      Securities or Option Securities, as the case may be, to be purchased by
      all of the Underwriters at such time hereunder, and if arrangements
      satisfactory to the Representatives are not made within 36 hours after
      such default for the purchase by other persons (who may include one or
      more of the non-defaulting Underwriters, including the Representatives) of
      the Securities with respect to which such default occurs, this Agreement
      will terminate without liability on the part of any non-defaulting
      Underwriter, the Company or any Selling Securityholder other than as
      provided in Section 12 hereof. In the event of any default by one or more
      Underwriters as described in this Section 11, the Representatives shall
      have the right to postpone the Firm Closing Date or the Option Closing
      Date, as the case may be, established as provided in Section 4 hereof for
      not more than seven business days in order that any necessary changes may
      be made in the


                                      -28-
<PAGE>   29

      arrangements or documents for the purchase and delivery of the Firm
      Securities or Option Securities, as the case may be. As used in this
      Agreement, the term "Underwriter" includes any person substituted for an
      Underwriter under this Section 11. Nothing herein shall relieve any
      defaulting Underwriter from liability for its default.

             12. Survival. The respective representations, warranties,
      agreements, covenants, indemnities and other statements of the Company,
      its officers, each Selling Securityholder and the several Underwriters set
      forth in this Agreement or made by or on behalf of them, respectively,
      pursuant to this Agreement shall remain in full force and effect,
      regardless of (i) any investigation made by or on behalf of the Company,
      any of its officers or directors, any Selling Securityholder, any
      Underwriter or any controlling person referred to in Section 10 hereof and
      (ii) delivery of and payment for the Securities. The respective
      agreements, covenants, indemnities and other statements set forth in
      Sections 8 and 10 hereof shall remain in full force and effect, regardless
      of any termination or cancellation of this Agreement.

             13. Termination. (a) This Agreement may be terminated with respect
      to the Firm Securities or any Option Securities in the sole discretion of
      the Representatives by notice to the Company and the Selling
      Securityholders given prior to the Firm Closing Date or the related Option
      Closing Date, respectively, in the event that the Company or any Selling
      Securityholder shall have failed, refused or been unable to perform all
      obligations and satisfy all conditions on its part to be performed or
      satisfied hereunder at or prior thereto or, if at or prior to the Firm
      Closing Date or such Option Closing Date, respectively,

                    (i) the Company or any of its subsidiaries shall have, in
            the sole judgment of the Representatives, sustained any material
            loss or interference with their respective businesses or properties
            from fire, flood, hurricane, accident or other calamity, whether or
            not covered by insurance, or from any labor dispute or any legal or
            governmental proceeding or there shall have been any material
            adverse change, or any development involving a prospective material
            adverse change (including without limitation a change in management
            or control of the Company), in the condition (financial or
            otherwise), business, prospects, net worth or results of operations
            of the Company and its subsidiaries, taken as a whole, except in
            each case as described in or contemplated by the Prospectus
            (exclusive of any amendment or supplement thereto);

                (ii) trading in the Common Stock shall have been suspended by
            the Commission or the Nasdaq National Market or trading in
            securities generally on the New York Stock Exchange or the Nasdaq
            National Market shall have been suspended or minimum or maximum
            prices shall have been established on such exchange.

                (iii) a banking moratorium shall have been declared by New York
             or United States authorities; or

                (iv) there shall have been (A) an outbreak or escalation of
             hostilities between the United States and any foreign power, (B) an
             outbreak or escalation of any other insurrection or armed conflict
             involving the United States or (C) any other calamity or crisis or
             material adverse change in general economic, political or financial
             conditions having an effect on the U. S. financial markets that, in
             the sole judgment of the Representatives, makes it impractical or
             inadvisable to proceed with the public offering or the delivery of
             the Securities as contemplated by the Registration


                                      -29-
<PAGE>   30

             Statement, as amended as of the date hereof.

             (b) Termination of this Agreement pursuant to this Section 13 shall
      be without liability of any party to any other party except as provided in
      Section 12 hereof.

             14. Information Supplied by Underwriters. The statements set forth
      in the last paragraph on the front cover page and under the heading
      "Underwriting" in any Preliminary Prospectus, the Prospectus or any
      Integrated Prospectus (to the extent such statements relate to the
      Underwriters) constitute the only information furnished by any Underwriter
      through the Representatives to the Company for the purposes of Sections
      2(b) and 10 hereof. The Underwriters confirm that such statements (to such
      extent) are correct.

             15. Notices. All communications hereunder shall be in writing and,
      if sent to any of the Underwriters, shall be delivered or sent by mail,
      telex or facsimile transmission and confirmed in writing to Prudential
      Securities Incorporated, One New York Plaza, New York, New York 10292,
      Attention: Equity Transactions Group; if sent to the Company, shall be
      delivered or sent by mail, telex or facsimile transmission and confirmed
      in writing to the Company at Telcom Semiconductor, Inc., 1300 Terra Bella
      Avenue, Mountain View, California 94039; and if sent to the Selling
      Securityholders, shall be delivered or sent by mail, telex or facsimile
      transmission and confirmed in writing to the Selling Securityholders at
      the foregoing address for the Company.

             16. Successors. This Agreement shall inure to the benefit of and
      shall be binding upon the several Underwriters, the Company, the Selling
      Securityholders and their respective successors and legal representatives,
      and nothing expressed or mentioned in this Agreement is intended or shall
      be construed to give any other person any legal or equitable right, remedy
      or claim under or in respect of this Agreement, or any provisions herein
      contained, this Agreement and all conditions and provisions hereof being
      intended to be and being for the sole and exclusive benefit of such
      persons and for the benefit of no other person except that (i) the
      indemnities of the Company and the Selling Securityholders contained in
      Section 10 of this Agreement shall also be for the benefit of any person
      or persons who control any Underwriter within the meaning of Section 15 of
      the Act or Section 20 of the Exchange Act and (ii) the indemnities of the
      Underwriters contained in Section 10 of this Agreement shall also be for
      the benefit of the directors of the Company, the officers of the Company
      who have signed the Registration Statement, the Selling Securityholders
      and any person or persons who control the Company or any Selling
      Securityholder within the meaning of Section 15 of the Act or Section 20
      of the Exchange Act. No purchaser of Securities from any Underwriter shall
      be deemed a successor because of such purchase.

             17. Applicable Law. The validity and interpretation of this
      Agreement, and the terms and conditions set forth herein, shall be
      governed by and construed in accordance with the laws of the State of New
      York, without giving effect to any provisions relating to conflicts of
      laws.

              18. Consent to Jurisdiction and Service of Process. All judicial
      proceedings arising out of or relating to this Agreement may be brought in
      any state or federal court of competent jurisdiction in the State of New
      York, and by execution and delivery of this Agreement, each Selling
      Securityholder accepts, generally and unconditionally, the nonexclusive
      jurisdiction of the aforesaid courts and waives any defense of forum non
      conveniens and irrevocably agrees to be bound by any judgment rendered
      thereby in connection with this Agreement. Each Selling Securityholder
      designates and appoints Phillip M. Drayer, and such other persons as may
      hereafter be selected by the Selling Securityholders irrevocably agreeing
      in writing to so serve, as its agent to receive on its behalf service of
      all process in any such proceedings in any such court,



                                      -30-
<PAGE>   31

      such service being hereby acknowledged by each Selling Securityholder to
      be effective and binding service in every respect. A copy of any such
      process so served shall be mailed by registered mail to each Selling
      Securityholder at its address provided in Section 15 hereof; provided,
      however, that, unless otherwise provided by applicable law, any failure to
      mail such copy shall not affect the validity of service of such process.
      If any agent appointed by the Selling Securityholders refuses to accept
      service, each Selling Securityholder hereby agrees that service of process
      sufficient for personal jurisdiction in any action against such Selling
      Securityholder in the State of New York may be made by registered or
      certified mail, return receipt requested, to the Selling Securityholder at
      its address provided in Section 15 hereof, and each Selling Securityholder
      hereby acknowledges that such service shall be effective and binding in
      every respect. Nothing herein shall affect the right to serve process in
      any other manner permitted by law or shall limit the right of any
      Underwriter to bring proceedings against the Selling Securityholders in
      the courts of any other jurisdiction.

             19. Counterparts. This Agreement may be executed in two or more
      counterparts, each of which shall be deemed an original, but all of which
      together shall constitute one and the same instrument.

      If the foregoing correctly sets forth our understanding, please indicate
      your acceptance thereof in the space provided below for that purpose,
      whereupon this letter shall constitute an agreement binding the Company
      and each of the several Underwriters.

                                                   Very truly yours,

        RE:    REGISTRATION STATEMENT ON FORM S-3

Ladies and Gentlemen:

        We have examined the registration statement on Form S-3, as amended,
filed by TelCom Semiconductor, Inc, a Delaware corporation (the "Company"), with
the Securities and Exchange Commission in connection with the registration under
the Securities Act of 1933, as amended, of 3,190,000 shares of the Company's
common stock of which 3,000,000 shares are to be sold by the Company and 190,000
shares are to be sold by certain stockholders of the Company (the "Selling
Stockholders"), plus an over-allotment option of up to 478,500 shares of the
Company's common stock granted to the underwriters of which 378,999 shares are
to be sold by the Company and 100,000 shares are to be sold by the Selling
Stockholders (collectively, the "Shares"). The Shares are to be sold to the
underwriters for resale to the public as described in the registration statement
and pursuant to the underwriting agreement filed as an exhibit thereto.

        As legal counsel to the Company and the Selling Stockholders with
respect to matters in connection with the public offering, we have examined the
proceedings proposed to be taken in connection with said sale and issuance of
the Shares. Based upon the foregoing, we are of the opinion that the Shares,
when issued and sold by the Company and when sold by the Selling Stockholders,
each in the manner described in the registration statement, will be duly
authorized, validly issued, fully paid and non-assessable. We consent to the use
of this opinion as an exhibit to the registration statement, and further consent
to the use of our name wherever appearing in the registration statement,
including the prospectus constituting a part thereof, and any amendment thereto.


                             Very truly yours,

                             /s/ Wilson Sonsini Goodrich & Rosati
