                             AMKOR TECHNOLOGY, INC.

                   RETIREMENT SEPARATION AGREEMENT AND RELEASE

     This Retirement Separation Agreement and Release ("Agreement") is made by
and between Amkor Technology, Inc. (the "Company"), and John N. Boruch
("Executive").

     WHEREAS, Executive is employed by the Company and serves on its Board of
Directors and now wishes to retire;

     WHEREAS, the Company and Executive have entered into the stock option
agreements listed on Exhibit A;

     NOW THEREFORE, the Company and Executive (collectively referred to as "the
Parties") hereby agree as follows:

     1. Termination. As a result of Executive's decision to retire, Executive's
employment from the Company will terminate effective as of December 30, 2005 and
Executive agrees to resign, effective as of the Effective Date (as such term is
defined in Section 22), all positions with the Company, including any
directorship of the Company or any of its affiliates or subsidiaries.

     2. Consideration. In exchange for the Executive's covenants set forth in
this Agreement and contingent upon the Executive signing and not revoking the
release contained in Sections 4 and 5 the Company agrees to provide Executive
with the following:

          (a) Severance Pay. The Company agrees to pay Executive, on or before
January 31, 2006, one million, eight hundred and twenty-three thousand dollars
($1,823,000), less applicable withholding in accordance with the Company's
payroll practices.

          (b) Stock Options. As of December 31, 2005, each of the Stock Options
will be amended to provide that it is fully vested, to the extent that it was
not previously fully vested, and each option will be modified to provide that it
will remain exercisable until December 31, 2008 (subject to the following). If
the Term/Expiration date (as such term is used in the applicable stock option
agreement) of a Stock Option occurs prior to December 31, 2008, then such Stock
Option shall expire no later than the applicable Term/Expiration date. Executive
specifically acknowledges that he has discussed the potential tax consequences
of these modifications with his personal tax advisors and he agrees to bear any
tax liability related to such modifications.

          (c) Subsidized COBRA. If Executive timely elects to continue his
health insurance coverage pursuant to the Consolidated Omnibus Budget
Reconciliation Act of 1986 ("COBRA"), the Company will reimburse Executive for
all COBRA premiums for eighteen (18) months unless COBRA coverage earlier
terminates.

          (d) Transfer of Automobile. By January 31, 2005, the Company will
transfer the ownership of the 2004 Lexus Lx 470 (VIN JTHT00WD43544465) to
Executive. Executive will bear all responsibility for taxes and liability
related to the transfer and to the automobile after the date of transfer.

     3. Payment of Salary. Executive acknowledges and represents that the
Company has paid all salary, wages, bonuses, accrued vacation, commissions and
any and all other benefits due to Executive, other than those accrued amounts
that will be paid during the final paycheck paid to Executive for the period
ending December 30, 2005.

     4. Release of Claims. Executive agrees that the foregoing consideration
represents settlement in full of all outstanding obligations owed to Executive
by the Company. Executive, on behalf of himself, and his respective heirs,
family members, executors and assigns, hereby fully and forever releases the
Company and its past, present and future officers, agents, directors, employees,
investors, shareholders, administrators, affiliates, divisions, subsidiaries,
parents, predecessor and successor corporations, and assigns (collectively, the
"Releasees"), from, and agrees not to sue or otherwise institute or cause to be
instituted any legal or administrative proceedings concerning any claim, duty,
obligation or cause of action relating to any matters of any kind, whether
presently known or unknown, suspected or unsuspected, that he may possess
arising from any omissions, acts or facts that have occurred up until and
including the Effective Date of this Agreement including, without limitation,

          (a) any and all claims relating to or arising out of Executive's
employment relationship with the Company and the termination of that
relationship;

          (b) any and all claims relating to, or arising from, Executive's right
to purchase, or actual purchase of shares of stock of the Company, including,
without limitation, any claims for fraud, misrepresentation, breach of fiduciary
duty, breach of duty under applicable state corporate law, and securities fraud

          (d) any and all claims for violation of any federal, state or
municipal statute, including, but not limited to, Title VII of the Civil Rights
Act of 1964; the Civil Rights Act of 1991; the Americans with Disabilities Act
of 1990; the Fair Labor Standards Act; the Fair Credit Reporting Act; the Age

<PAGE>

          (e) any and all claims for violation of the federal, or any state,
constitution;

          (f) any and all claims arising out of any other laws and regulations
relating to employment or employment discrimination; and

          (g) any and all claims for attorneys' fees and costs.

     Executive acknowledges and agrees that any breach by him of this paragraph
or of his obligations under paragraphs 8, 9, 10, 11, or 12 hereof shall
constitute a material breach of this Agreement, and shall entitle the Company
immediately to cease paying COBRA premium reimbursements pursuant to Section
2(c) and the stock option modifications provided in Section 2(b) shall be null
and void and such stock options shall immediately expire. Further, Executive
acknowledges and agrees that any breach by him of this paragraph or of his
obligations under paragraphs 8, 9, 10, 11, or 12 hereof shall constitute a
material breach of this Agreement and shall entitle the Company immediately to
recover any other consideration provided to Executive by this Agreement, except
as prohibited by law. Except as prohibited by law, Executive shall also be
responsible to the Company for all costs, attorneys' fees and any and all
damages incurred by the Company in: (a) enforcing his obligations under this
paragraph, paragraphs 8, 9, 10, 11, or 12, including the bringing of any action
to recover the consideration, and (b) defending against a claim brought or
pursued by Executive in violation of the terms of this Agreement.

     5. Acknowledgment of Waiver of Claims under ADEA. Executive acknowledges
that he is waiving and releasing any rights he may have under the Age
Discrimination in Employment Act of 1967 ("ADEA") and that this waiver and
release is knowing and voluntary. Executive and the Company agree that this
waiver and release does not apply to any rights or claims that may arise under
ADEA after the Effective Date of this Agreement. Executive acknowledges that the
consideration given for this waiver and release Agreement is in addition to
anything of value to which Executive was already entitled. Executive further
acknowledges that he has been advised by this writing that

          (a) he should consult with an attorney prior to executing this
Agreement;

          (b) he has up to twenty-one (21) days within which to consider this
Agreement;

          (c) he has seven (7) days following his execution of this Agreement to
revoke this Agreement;

          (d) this Agreement shall not be effective until the revocation period
has expired; and,

     nothing in this Agreement prevents or precludes Executive from challenging
or seeking a determination in good faith of the validity of this waiver under
the ADEA, nor does it impose any condition precedent, penalties or costs for
doing so, unless specifically authorized by federal law. Any revocation should
be in writing and delivered to Ken Joyce at Amkor Technology at 1900 South Price
Road, Chandler, Arizona 85248, by close of business on the seventh day from the
date that Executive signs this Agreement.

                                       -3-

     6. Unknown Claims. Executive represents that he is not aware of any claim
other than the claims that are released by this Agreement. Executive
acknowledges that he has been advised by legal counsel and is familiar with the
principle that a general release does not extend to claims which the releasor
does not know or suspect to exist in his favor at the time of executing the
release, which if known by him must have materially affected his settlement with
the Releasees. Executive, being aware of said principle, agrees to expressly
waive any rights he may have to that effect, as well as under any other statute
or common law principles of similar effect.

     7. No Pending or Future Lawsuits. Executive represents that he has no
lawsuits, claims, or actions pending in his name, or on behalf of any other
person or entity, against the Company or any other person or entity referred to
herein. Executive also represents that he does not intend to bring any claims on
his own behalf or on behalf of any other person or entity against the Company or
any other person or entity referred to herein.

     8. Trade Secrets and Confidential Information/Company Property. Executive
agrees at all times hereafter to hold in the strictest confidence, and not to
use or disclose to any person or entity, any trade secrets, proprietary or
confidential information of the Company. Executive represents that he has not to
date misused or disclosed any of the Company's trade secrets, proprietary and
confidential information, to any unauthorized parties. Executive's signature
below constitutes his certification under penalty of perjury that he has
returned all documents and other items provided to Executive by the Company,
developed or obtained by Executive as a result of his employment with the
Company, or otherwise belonging to the Company.

     9. Non-Competition and Non-Solicitation.

          (a) Until the Noncompetition and Nonsolicitation End Date (as defined
in Section 9(b)(i), Executive agrees not to enter into an employment or
consulting relationship with any Prohibited Entity, as defined in Section
9(b)(ii). Executive specifically acknowledges and agrees that the provisions of
this Section 9 are no broader than necessary to protect the Company's legitimate
business interests and that Executive's knowledge of the Company's business make
the prospect of his entering into business with a competitor of the Company
uniquely harmful to the Company. Executive further acknowledges that the cash
severance payments made pursuant to Section 2(a) are not required by the terms
of any existing agreement and are being made by the Company in exchange for the
non-competition and non-solicitation covenants contained in this Section 9.

          (b) Definitions:

               (i) Noncompetition and Nonsolicitation End Date shall mean:

                    (1)  December 31, 2008;

                    (2) If a court determines that the definition in Section
9(b)(i)(1) makes the covenant in Section 9(a) too broad to be enforceable, then
Noncompetition and Nonsolicitation End Date shall mean December 31, 2007;

                                       -4-

<PAGE>

                    (3) If a court determines that the definitions in Section
9(b)(i)(1) and (9)(b)(i)(2) each make the covenant in Section 9(a) too broad to
be enforceable, then Noncompetition and Nonsolicitation End Date shall mean
December 31, 2006.

               (ii) Prohibited Entity shall mean the most expansive of the
following definitions:

                    (1) Any company that is engaged in outsourced contract
semiconductor assembly and test services throughout the world. Executive
specifically acknowledges and agrees that the scope of the Company's business is
worldwide and that therefore this definition of Prohibited Entity is
appropriate;

                    (2) If a court determines that the definition in Section
9(b)(ii)(1) makes the covenant in Section 9(a) too broad to be enforceable, then
Prohibited Entity shall mean any company engaged in contract semiconductor
assembly and test services in the United States. Executive specifically
acknowledges and agrees that the scope of the Company's business is throughout
the United States and that therefore this definition of Prohibited Entity is
appropriate.

                    (3) If a court determines that the definitions in Sections
9(b)(ii)(1) and 9(b)(ii)(2) each make the covenant in Section 9(a) too broad to
be enforceable, then Prohibited Entity shall mean any of the following
companies, each of which Executive specifically acknowledges and agrees is a
direct competitor of the Company:

                         a)   Advanced Semiconductor Engineering, Inc.,

                         b)   ASE Test Limited,

                         c)   ASAT Ltd.,

                         d)   STATS ChipPAC Ltd., and

                         e)   Siliconware Precision Industries Co., Ltd.

          (c) Until the Noncompetition and Nonsolicitation End Date, Executive
separately agrees not to solicit any employees of the Company to leave the
employment of the Company or to solicit business from or enter into a consulting
or employment relationship with any key customer of the Company, including but
not limited to:

                    (1)  Toshiba

                    (2)  Intel

                    (3)  Samsung

                    (4)  IBM

disclosure of any Settlement Information to third parties, and agrees that there

or other court order to do so. Executive agrees to cooperate in providing
assistance and information to the Company as reasonably requested in the future
and the Company agrees that it shall pay Executive at rate of $2,500 per day in
exchange for such cooperation.

     12. Non-Disparagement. Executive agrees to refrain from any defamation,
libel or slander of the Company and its respective officers, directors,

corporations, and assigns.

     15. Arbitration. The Parties agree that any and all disputes arising out
of, or relating to, the terms of this Agreement, their interpretation, and any

void, this Agreement shall continue in full force and effect without said
provision.

     19. Entire Agreement. This Agreement and the Stock Options represent the
entire agreement and understanding between the Company and Executive concerning
Executive's retirement from the Company, and supersede and replace any and all

                   AGREEMENT TO PURCHASE AND SELL SECURITIES.

     2.1. Agreement to Purchase and Sell Securities. The Company hereby agrees
to issue to each Investor at the Closing (as defined below) the principal amount
of Notes set forth next to each Investor's name on Schedule I and each Investor
agrees to purchase from the Company at the Closing, for an aggregate purchase
price set forth next to each Investor's name on Schedule I (together, "Purchase
Price"), the Notes.

     2.2. The Closing. The purchase and sale of the Notes shall take place at
the offices of Wilson Sonsini Goodrich & Rosati, P.C., 650 Page Mill Road, Palo
Alto, California 94304, at 10:00 a.m. California time, on November 18, 2005, or

                                   SECTION 3.

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

     The Company hereby represents and warrants to each Investor that the
statements in this Section 3 are true and correct, except as disclosed in the
SEC Documents (as defined below):

     3.1. Organization Good Standing and Qualification. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware and has all corporate power and authority required to
(a) carry on its business as presently conducted, and (b) enter into the
Transaction Documents, to issue the Notes and the shares of Common Stock
issuable upon conversion of the Notes pursuant to the Indenture and to
consummate the transactions contemplated hereby and thereby. The Company is
qualified to do business and is in good standing in each jurisdiction in which
the failure to so qualify would have a Material Adverse Effect. As used in this
Agreement, "Material Adverse Effect" means a material adverse effect, or a group
of such effects which are related, on the business, operations, condition
(financial or otherwise) or results of operations, of the applicable party and
its Subsidiaries, taken as a whole.

                                      -3-

in all material respects to the description thereof in the SEC Documents.

     3.3. Due Authorization. The Company has the requisite corporate power and
authority to enter into the Transaction Documents and to perform its obligations
hereunder and thereunder. The execution and delivery of the Transaction
Documents and performance by the Company of its obligations hereunder and
thereunder, including without limitation, the issuance of the Notes, have been
duly authorized by all necessary corporate action on the part of the Company
(including its directors and stockholders). The Transaction Documents, when
executed and delivered by the parties thereto, will constitute, valid and
legally binding obligations of the Company, enforceable against the Company in
accordance with their respective terms, except (a) as may be limited by (i)
applicable bankruptcy, insolvency, reorganization or others laws of general
application relating to or affecting the enforcement of creditors' rights
generally and (ii) the effect of rules of law governing the availability of
equitable remedies and (b) as rights to indemnity or contribution may be limited
under federal or state securities laws or by principles of public policy
thereunder.

     3.4. Valid Issuance.

          (a) Valid Issuance and Enforceability of Notes. The Notes have been
duly authorized and, when executed and authenticated in accordance with the
provisions of the Indenture and delivered to and paid for by the Investors in
accordance with the terms of this Agreement, will be valid and binding
obligations of the Company, enforceable in accordance with their terms, subject
to applicable bankruptcy, insolvency or similar laws affecting creditors' rights
generally and general principles of equity, and will be entitled to the benefits
provided for in the Indenture.

          (b) Valid Issuance of Common Stock. The Common Stock initially
issuable upon conversion of the Notes (the "Underlying Securities") and reserved
for issuance upon conversion of the Notes has been duly authorized and reserved
and, when issued upon conversion of the Notes in accordance with the terms of
the Notes and the Indenture, will be validly issued, fully paid and
non-assessable, and the issuance of the Underlying Securities will not be
subject to any preemptive or similar rights.

     3.5. Compliance with Securities Laws. Assuming the accuracy of the
representations made by Investors in Section 4 hereof, the Notes and the shares
of Common Stock issuable upon conversion of the Notes pursuant to the Indenture
will be issued to Investors in compliance with applicable exemptions from (i)
the registration and prospectus delivery requirements of the Securities Act and
(ii) the registration and qualification requirements of all applicable
securities laws of the states of the United States.

this Agreement, except: (i) the filing of a current report on Form 8-K by the
Company with the SEC following the Closing; (ii) the filing of such

applicable state securities laws as may be required in connection with the
transactions contemplated by this Agreement; and (iii) as expressly required or
contemplated by the terms of the Transaction Documents. All such qualifications
and filings in connection with the issuance of the Notes have been made or are
effective.

     3.7. Non-Contravention. The execution, delivery and performance of the
Transaction Documents by the Company, and the consummation by the Company of the
transactions contemplated hereby and thereby, do not and will not (i) contravene
or conflict with the Certificate of Incorporation or Bylaws of the Company, as
amended; (ii) constitute a violation of any provision of any federal, state,
local or foreign law binding upon or applicable to the Company; or (iii)
constitute a default or require any consent under, give rise to any right of
termination, cancellation or acceleration of, or to a loss of any benefit to
which the Company is entitled under, or result in the creation or imposition of
any lien, claim or encumbrance on any assets of the Company under, any material
contract to which the Company is a party or any permit, license or similar right
relating to the Company or by which the Company may be bound, except in the case
of clause (ii) and clause (iii) as, individually or in the aggregate, would not
reasonably be expected to have a Material Adverse Effect.

     3.8. Litigation. There is no action, suit, proceeding, claim, arbitration
or investigation ("Action") pending: (a) against the Company, its properties or
assets or, to the best of the Company's knowledge, against any officer, director
or employee of the Company in connection with such officer's, director's or
employee's relationship with, or actions taken on behalf of, the Company, which
the Company believes is reasonably likely to have a Material Adverse Effect, or
(b) that seeks to prevent, enjoin, alter or delay the transactions contemplated
by this Agreement. The Company is not a party to or subject to the provisions of
any order, writ, injunction, judgment or decree of any court or government
agency or instrumentality which it believes is reasonably likely to have a
Material Adverse Effect. No Action by the Company is currently pending nor does
the Company intend to initiate any Action which it believes is reasonably likely
to have a Material Adverse Effect.

     3.9. Compliance with Law and Charter Documents. The Company is not in
violation or default of any provisions of its Certificate of Incorporation or
Bylaws, both as amended. The Company has complied and is in compliance with all
applicable statutes, laws, and regulations and executive orders of the United
States of America and all states, foreign countries and other governmental
bodies and agencies having jurisdiction over the Company's business, assets or
properties, except for any violations that would not, either individually or in
the aggregate, have a Material Adverse Effect.

          (a) Reports. The Company has filed all required forms, reports and
documents with the SEC since December 31, 2004. The Company has furnished or

                                      -5-

<PAGE>

fiscal quarters ended March 31, 2005, June 30, 2005 and September 30, 2005 (the
"Form 10-Q's"), and all other registration statements, reports and proxy
statements filed by the Company with the SEC on or after December 31, 2004 (the
Form 10-K, the Form 10-Q's and such registration statements, reports and proxy
statements are collectively referred to herein as the "SEC Documents"). Each of
the SEC Documents, as of the respective date thereof (or if amended or
superseded by a filing prior to the closing date of this Agreement, then on the
date of such filing), did not, and each of the registration statements, reports
and proxy statements filed by the Company with the SEC after the date hereof and
prior to the Closing will not, as of the date thereof (or if amended or
superseded by a filing prior to the date of this Agreement, then on the date of
such filing), contain any untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements made therein, in light
of the circumstances under which they were made, not misleading. The Company is
not a party to any material contract, agreement or other arrangement which was
required to have been filed as an exhibit to the SEC Documents that was not so
filed.

          (b) Financial Statements. The SEC Documents include the Company's
audited consolidated financial statements (the "Audited Financial Statements")
for the fiscal year ended December 31, 2004 (the "Balance Sheet Date"), and its
unaudited consolidated financial statements for the nine-month period ended
September 30, 2005. The audited and unaudited consolidated financial statements
of the Company included in the SEC Documents filed prior to the date hereof
fairly present, in conformity with United States generally accepted accounting
principles ("GAAP") (except as permitted by Form 10-Q) applied on a consistent
basis (except as may be indicated in such financial statements or the notes
thereto), the consolidated financial position of the Company and its
consolidated Subsidiaries as at the dates thereof and the consolidated results
of their operations and cash flows for the periods then ended (subject to normal
year-end audit adjustments in the case of the unaudited interim financial
statements contained in the Form 10-Qs, which adjustments are not expected to be
material in amount).

          (c) No Integration. Neither the Company nor any affiliate (as defined
in Rule 501(b) of Regulation D under the Securities Act) of the Company has
directly, or through any agent, (i) sold, offered for sale, solicited offers to
buy or otherwise negotiated in respect of, any security (as defined in the
Securities Act) which is or will be integrated with the sale of the Notes in a
manner that would require the registration under the Securities Act of the
Notes, (ii) engaged in any form of general solicitation or general advertising
in connection with the offering of the Notes (as those terms are used in
Regulation D under the Securities Act), or in any manner involving a public
offering within the meaning of Section 4(2) of the Securities Act, (iii) taken,
directly or indirectly, any action designed to cause or result in, or which has
constituted or which might reasonably be expected to constitute, the
stabilization or manipulation of the price of the Notes or the Underlying
Securities to facilitate the sale or resale of such Notes or the Underlying
Securities, or (iv) entered into any contractual arrangement with respect to the
distribution of the Notes or the Underlying Securities except for this Agreement
and the Company will not enter into any such arrangement except for the
Investors Rights Agreement and as may be contemplated thereby.

                                      -6-

<PAGE>

          (d) Registration; Qualification. It is not necessary in connection
with the offer, sale and delivery of the Notes to Investors in the manner
contemplated by this Agreement to register the Notes under the Securities Act or
to qualify the Indenture under the Trust Indenture Act of 1939, as amended.

          (e) Rule 144A(d)(3). The Notes satisfy the requirements set forth in
Rule 144A(d)(3) under the Securities Act.

                                   SECTION 4.

            REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF INVESTORS.

     Each Investor represents, warrants and agrees, severally and not jointly,
with respect to itself only, to the Company as follows:

     4.1. Investigation; Economic Risk. Each Investor has received or has had
full access to all of the information it considers necessary or appropriate to
make an informed investment decision with respect to the Notes to be purchased
by each Investor under this Agreement. Each Investor further has had an
opportunity to ask questions and receive answers from the Company regarding the
terms and conditions of the offering of the Notes and the Underlying Securities
and to obtain additional information (to the extent the Company possessed such
information or could acquire it without unreasonable effort or expense)
necessary to verify any information furnished to such Investor or to which such
Investor had access. Each Investor understands that the purchase of the Notes
and any Underlying Securities involves substantial risk. Each Investor
acknowledges that it is able to fend for itself in the transactions contemplated
by this Agreement and has the ability to bear the economic risks of its
investment pursuant to this Agreement and has such knowledge and experience in
financial or business matters that it is capable of evaluating the merits and
risks of this investment in the Notes and the Underlying Securities and
protecting its own interests in connection with this investment. Each Investor
has consulted, or has been provided the opportunity to consult with, independent
advisors (including counsel and tax and accounting advisors) as needed to make
its investment decision and to determine whether it is legally permitted to
purchase the Notes under applicable legal investment or similar laws or
regulations.

     4.2. Purchase for Own Account. Each Investor will acquire the Notes for its
own account, not as a nominee or agent, and not with a view to or in connection
with the sale or distribution of any part thereof.

     4.3. Exempt from Registration; Restricted Securities. Except as set forth
in the Investors Rights Agreement, each Investor understands that the sale and
issuance of the Notes and the Underlying Securities will not be registered under
the Securities Act on the ground that the sale provided for in this Agreement is
exempt from registration under of the Securities Act, and that the reliance of
the Company on such exemption is predicated in part on such Investors'
representations set forth in this Agreement. Each Investor understands that the
Notes and the Underlying Securities are restricted securities within the meaning
of Rule 144 under the Securities Act, and must be held

                                      -7-

<PAGE>

indefinitely unless they are subsequently registered or an exemption from such
registration is available. Each Investor understands that the Company is under
no obligation to register any of the securities sold hereunder except as
provided in the Investors Rights Agreement. Each Investor understands that there
are restrictions with respect to the transfer, offer, pledge or sale of the
Notes prior to November 18, 2006 (the "Holding Period Termination Date"), and
that the Indenture for the Notes contains provisions that restrict any transfer
of the Notes by the Trustee prior to the Holding Period Termination Date.

     4.4. Accredited Investors. Each Investor is, or prior to the date of the
Closing will be, an "accredited investor" as that term is defined in Rule 501(a)
of Regulation D promulgated by the SEC under the Securities Act.

     4.5. Legends. Each Investor agrees that the Notes and the Underlying
Securities will bear legends and be subject to the restrictions on transfer as
provided in the Indenture. In addition, each Investor agrees that the Company
may place stop transfer orders with its transfer agents with respect to such
instruments. The appropriate portion of the legend shall be removed in
accordance with the provisions of the Indenture and the stop transfer orders
shall be removed promptly upon delivery to the Company of such satisfactory
evidence as reasonably may be required by the Company that such stop orders are
not required to ensure compliance with the Securities Act.

     4.6. Due Authorization. Each Investor has the requisite authority to enter
into the Transaction Documents and to perform its obligations hereunder and
thereunder. The execution and delivery of the Transaction Documents and
performance by each Investor of its obligations hereunder and thereunder, have
been duly authorized by all necessary action on the part of such Investor. The
Transaction Documents, when executed and delivered by the parties thereto, will
constitute, valid and legally binding obligations of each Investor, enforceable
against each Investor in accordance with their respective terms, except (a) as
may be limited by (i) applicable bankruptcy, insolvency, reorganization or
others laws of general application relating to or affecting the enforcement of
creditors' rights generally and (ii) the effect of rules of law governing the
availability of equitable remedies and (b) as rights to indemnity or
contribution may be limited under federal or state securities laws or by
principles of public policy thereunder.

     4.7. Governmental Consents. No consent, approval, order or authorization
of, or registration qualification, designation, declaration or filing with, any
federal, state or local governmental authority on the part of each Investor is
required in connection with the consummation of the transactions contemplated by
this Agreement, except as expressly required or contemplated by the terms of the
Transaction Documents.

     4.8. Non-Contravention. The execution, delivery and performance of the
Transaction Documents and the consummation by each Investor of the transactions
contemplated hereby and thereby, do not and will not (i) constitute a violation
of any provision of any federal, state, local or foreign law binding upon or
applicable to such Investor; or (ii) constitute a default or require any consent
under, give rise to any right of termination, cancellation or acceleration of,
or to a loss of any benefit to which such Investor is entitled under, or result
in the creation or imposition of any

                                      -8-

<PAGE>

lien, claim or encumbrance on any assets of such Investor under, any contract to

                                    EXHIBIT A

          FORM OF WILSON SONSINI GOODRICH & ROSATI, P.C. LEGAL OPINION

     1. The Company has been duly incorporated, is validly existing as a
corporation in good standing under the laws of Delaware.

     2. Each of the Note Purchase Agreement, Indenture and the Investors Rights
Agreement has been duly authorized, executed and delivered by, and is a valid
and binding agreement of, the Company, enforceable against the Company in
accordance with its terms.

     3. The Notes have been duly authorized by the Company and, when executed
and authenticated in accordance with the provisions of the Indenture and
delivered to and paid for by the Investors in accordance with the terms of the
Note Purchase Agreement, will be valid and binding obligations of the Company,
enforceable against the Company in accordance with their terms, subject to
customary exceptions of such counsel.

     4. The shares of Common Stock initially issuable upon conversion of the
Notes (the "Conversion Shares") have been duly authorized and reserved and, when
issued upon conversion of the Notes in accordance with the terms of the Notes
and the Indenture, will be validly issued, fully paid and non-assessable.

     5. The issuance and sale of the Notes being delivered on the date hereof,
the issuance of the Conversion Shares, if any (assuming conversion on the date
hereof pursuant to the terms of the Notes and the Indenture) and the execution,
delivery and performance of the Indenture, the Notes, the Note Purchase
Agreement, and the Registration Rights Agreement, and the consummation of the
transactions therein contemplated, do not conflict with or did not result in a
breach or violation by the Company of any of the terms or provisions of, or
constitute a default under, any Reviewed Agreement, nor will such action result
in any violation of the provisions of the certificate of incorporation or the
bylaws of the Company or any U.S. federal or California state statute, rule or
order or regulation known to such counsel of any U.S. federal or California or
Delaware (under the DGCL) state court or governmental agency or body having
jurisdiction over the Company or any of its properties. For purposes of this
opinion, "Reviewed Agreement" shall mean those agreements currently in effect
that would be filed by the Company as an Exhibit to the Company's Annual Report
on Form 10-K as if such Report was filed on the date of such opinion.

     6. No consent, approval, authorization, order of, registration or
qualification of or with any U.S. federal or California or Delaware (under the
DGCL) state court or governmental agency or body is required for the issue and
sale of the Notes or the execution, delivery of and consummation by the Company
of the transactions contemplated by the Note Purchase Agreement, the
Registration Rights Agreement or the Indenture, except (i) the registration
under the Securities Act of 1933, as amended (the "Act") of the Notes and the
shares of Common Stock issuable upon conversion of the Notes as contemplated by
the Registration Rights Agreement and the qualification of the Indenture

under the Trust Indenture Act of 1939 (the "Trust Indenture Act"), and (ii) as
otherwise contemplated by the Transaction Documents.

     7. Assuming accuracy of the representations and warranties of the Company
and the Investors in the Note Purchase Agreement, no registration of the Notes
under the Securities Act is required for the sale of the Notes by the Company to
the Investors pursuant to the Note Purchase Agreement in the manner contemplated
by the Note Purchase Agreement (it being understood that no opinion is expressed
as to any subsequent resale of the Notes or the Conversion Shares).
