Item 2.   Acquisition or Disposition of Assets

     (a)  Pursuant to the Purchase Agreement dated as of March 10, 1997, by
and between the Registrant, Uniphase Laser Enterprise AG ("ULE"), a Swiss 
corporation and a wholly owned subsidiary of the Registrant, and 
International Business Machines Corporation ("IBM"), a New York corporation, 
the Registrant closed a transaction to acquire the assets (the "Assets") of  
"IBM Laser Enterprise," a part of IBM's Zurich Research Laboratory in 
Switzerland. The aggregate purchase price paid for the Assets was 
$45,000,000.00, which payment was made in cash.  The purchase price was 
determined during arms length negotiations between IBM the Registrant and 
ULE which took into account IBM Laser Enterprise's financial position, 
operating history, products, Intellectual property and other factors relating
to IBM Laser Enterprise's business and certain income tax aspects of the 
transaction. Except as set forth in the Exhibits hereto, there are no material
relationships between the Registrant or ULE and either of IBM or IBM Laser
Enterprise.

          The Registrant and ULE acquired the certain intellectual property
(non- exclusive technology and patent license agreement) and certain
tangible  assets(accounts receivable, fixed assets and inventories).
In addition to the assets, ULE and the  Registrant assumed certain
liabilities relating to  the Assets. As a part of the transaction, IBM
leased to ULE, for a period of 24 months, approximately 12,000 square
feet of office, cleanroom and laboratories space at the Zurich
Research Laboratory, at no additional consideration.  IBM and ULE further
agreed that IBM will provide certain services to ULE for the duration of
the lease periods, also at no additional consideration.  All of the
Assets will continue to be used by the Registrant and ULE in
conducting ULE's business, which prior to the completion of the
transaction involved the development, manufacture and sale of integrated
optical components.

          The source of funds used to purchase the Assets was cash from the
Registrant's existing working capital.

Item 7.   Financial Statements, Pro Forma Financial Information and Exhibits.

          (a)  Financial Statements of Businesses Acquired.

               It is impractical for Registrant to file the required
financial statements at this time. Registrant intends to
file such financial statements within 60 days of the date of this
report.

          (b)  Pro Forma Financial Information.

                            PURCHASE AGREEMENT


          THIS AGREEMENT, dated as of March 10, 1997, by and between
International Business Machines Corporation, a New York corporation
("Seller"), Uniphase Corporation, a Delaware corporation, and Uniphase
Laser Enterprise AG, a Swiss AG ("Buyer") (herein "Agreement");

                           W I T N E S S E T H:


          WHEREAS, Seller wishes to sell assets used in the manufacturing
of certain components (such assets being hereinafter referred to as the
"Transferred Assets") which business operations are currently conducted at
Seller's facility located at Reuschlikon, Canton Zurich, Switzerland; and

          WHEREAS, Buyer wishes to purchase from Seller, and Seller wishes
to sell to Buyer, the Transferred Assets for the purchase price and subject
to the terms and conditions hereinafter set forth;

          NOW, THEREFORE, in consideration of the premises set forth above
and the respective covenants, agreements, representations and warranties
hereinafter set forth, Buyer, Seller, and Uniphase Corporation
(collectively, the "Parties") hereby agree as follows:

Article I.     Purchase and Sale of Assets.

          Section 1.1.     Transferred Assets.      Upon the terms and
subject to the conditions hereof, as of the Closing Date (as defined in
Article 2.1 hereof), Seller hereby sells, transfers, conveys, assigns and
delivers to Buyer, and Buyer hereby purchases and accepts from Seller, all
right, title and interest of Seller in and to the items of equipment and
office furniture, and assets, including work in progress and accounts
receivable, listed on the sub-schedules of Schedule 1.1 hereto and spare
parts, as available for any of the items listed thereon, but excluding cash
accounts.  Intellectual property matters are addressed exclusively in the
Patent License Agreement and Technology License Agreement between the
Parties, dated as of the date of this Agreement (herein the "Intellectual
Property Agreements") and except as provided in Section 7.2. are not
otherwise a subject matter of this Agreement.

          All such scheduled assets and Assumed Liabilities (as defined
below) of Seller are collectively referred to herein as the "Transferred
Assets."  Wherever used in this Agreement, the term "affiliate" of any
person or entity shall mean any person or entity which is controlling,
controlled by or under common control with such person or entity.

          Seller shall also assign applicable third party warranties on the
Transferred Assets, to the extent legally permissible, and without
responsibility for compliance by the warranty grantors.

          Section 1.2.     Excluded Assets.      Notwithstanding anything
to the contrary in this Agreement or any agreements contemplated by this
Agreement, the following assets (collectively, the "Excluded Assets") will
be retained by Seller, and are excluded from the Transferred Assets:

          (a)  any interest in or right to use any trademark or service
mark owned by Seller or any of its affiliates, any associated logo or any
derivative of any thereof, either alone or in conjunction with other words;

          (b)  except as set forth in Schedule 1.4.B., any interest in any
contractual arrangement with Seller or any of its affiliates;

          (c)  all other assets of Seller or any of its affiliates not
expressly listed on Schedule 1.1 hereto; and

          (d)  except as provided in the Seller Lease (as defined in
Section 2.2(c) below), any interests of Seller or any of its affiliates in
real property.

          Section 1.3.     Consideration.     The Purchase Price for the
Transferred Assets and the licenses granted under the Intellectual Property
Agreements shall be $45,000,000 (forty-five million dollars).  Buyer shall
pay to Seller by electronic funds transfer, such sum in immediately
available funds at the Closing, in U.S. dollars.

          Section 1.4.     Assumed Liabilities.

          (a)  At the Closing, Seller will assign and transfer to Buyer,
and Buyer will assume, and thereafter shall fully perform and discharge, on
a timely basis and in accordance with their respective terms, the
liabilities and obligations of Seller listed on Schedule 1.4.A.1. and
Schedule 1.4.A.2., hereto (the "Assumed Liabilities").  Without limiting
the generality of the foregoing, except for the Assumed Liabilities and the
Buyer's obligations to the Employees under Swiss law, Buyer is not assuming
or undertaking any obligations or liabilities of Seller, to any assets or
contracts which are not included in the Transferred Assets or the Assumed
Liabilities.  Buyer is assuming and undertaking, and Seller shall not
remain liable for, any obligations or liabilities of Seller, contingent or
otherwise, whenever asserted, relating to periods prior to the Closing
Date, and work performed during such periods with respect to the Assumed
Liabilities, as set forth on Schedule 1.4.A.2., and such obligations and
liabilities are specifically included in the Assumed Liabilities.  The
Assumed Liabilities shall, except as otherwise set forth herein, exclude
liabilities and obligations of Seller with respect to periods prior to the
Closing Date, including, without limitation, any liabilities or payments
accruing with respect to the Assumed Liabilities for periods prior to the
Closing Date.  Any rights, liabilities and obligations of Seller to or from
any of its affiliates will not be transferred to Buyer, other than as set
forth in Schedule 1.4.B.

          (b)  The Parties will each use reasonable efforts to obtain
written consents to the transfer and assignment to Buyer of the Transferred
Assets and Assumed Liabilities, where the approval or other consent of any
other person may be required.  The Parties shall cooperate (including,
where necessary, entering into appropriate instruments of assumption as
shall be agreed upon) to have Seller released from all liability to third
parties with respect to the Assumed Liabilities, and the Parties will each
solicit such releases concurrently with the solicitation of consents from
third parties to the transfer and assignment to Buyer of the Transferred
Assets and the Assumed Liabilities; provided, that, neither Party shall be
required to grant any additional consideration to any third party in order
to obtain any such consent or release.

          Section 1.5.     Accounts Receivable.     The accounts receivable
listed on Schedule 1.5 are part of the Transferred Assets.  Such accounts
receivable are transferred subject to collection, with no representations
as to collectibility, or as to any minimum amount to be provided.  If such
accounts receivable exceed $5.5 million U.S., Buyer will repay such excess
to Seller within 15 business days of collection and in no event later than
90 days after the date of this Agreement.  If Buyer has notified Seller
within such 90-day period that Buyer has determined a portion of such
accounts receivable to be uncollectible, and if some accounts receivable
are deemed to be uncollectible as determined in good faith by both Parties,
the Seller shall receive from the Buyer no later than six months after the
Closing a final balancing payment for such uncollectible receivables; the
remaining accounts receivable transferred above $5.5 million U.S., reduced
by an amount calculated under the following formula:  the product of (i)
such uncollectible amounts, divided by the total accounts receivable
transferred at Closing; times (ii) the result of the total accounts
receivable transferred at Closing, less $5.5 million U.S.  An exchange rate
of 1.48 Swiss Francs for each U.S. dollar will be applied for those
receivables denominated in Swiss Francs.

Article II.     Closing.

          Section 2.1.     Closing Date.     The closing of the
transactions provided for in this Agreement (the "Closing") shall take
place on the date hereof (the "Closing Date") at the offices of Seller.
All transactions provided for herein to occur on and as of the Closing Date
shall be deemed to have occurred simultaneously and to be effective as of
the close of business on the Closing Date.

          Section 2.2.     Delivery by Buyer.     At the Closing, Buyer
will deliver or cause to be delivered to Seller the following:

          (a)  payment of the Purchase Price in the manner specified in

(the "Seller Lease"), duly executed by Buyer.

          (d)  Transitional Services Agreement in the form of Exhibit C

          (f)  a certificate of the Secretary of Uniphase Corporation as to
the By-laws of Uniphase Corporation and the resolutions of Uniphase
Corporation, and a power of attorney of the only member of the board of
directors of Buyer, authorizing the execution, delivery and performance of
this Agreement, the Intellectual Property Agreements, the Seller Lease, the
Assumption Agreement, the Transitional Services Agreement, and the future
Swiss Pension Transfer Agreement by either Buyer or Uniphase Corporation,
as applicable, and the persons acting on behalf of Buyer, executing such
Agreements and any document delivered in connection with such agreements at
the Closing.

          Section 2.3.     Delivery by Seller.     At the Closing, Seller
will deliver or cause to be delivered to Buyer the following:

          (a)  a bill of sale substantially in the form of Exhibit B hereto
(the "Bill of Sale"), duly executed by Seller, effectively vesting in Buyer
all right, title and interest of Seller in and to the tangible personal
property included in the Transferred Assets as provided in this Agreement;

          (b)  the Assumption Agreement, duly executed by Seller;

          (c)  the Seller Lease, duly executed by Seller;

          (d)  the Transitional Services Agreement, duly executed by
Seller;

          (e)  a certificate of the Secretary of Seller as to the By-laws
of Seller, and the delegations authorizing the execution, delivery and
performance of this Agreement, the Intellectual Property Agreements, the
Bill of Sale, the Seller Lease, the Assumption Agreement, the Transitional
Services Agreement and the future Swiss Pension Transfer Agreement, and as
to the incumbency of all officers of Seller executing this Agreement and
any document delivered in connection with this Agreement at the Closing.

Article III.     Tax Matters.

          Section 3.1.     Allocation of Purchase Price.     Buyer and
Seller agree on an estimated allocation of the Purchase Price as set forth
in Schedule 3.1. to the extent necessary to permit the making of timely
transfer tax filings.   In addition, as soon as practicable after the
Closing Date, but in no event not later than 90 days prior to the due date
of the Internal Revenue Service Form 8594, Buyer shall provide to Seller
proposed statements ("Allocation Statements") allocating the total of the
Purchase Price (and other payments properly treated as additional Purchase
Price for Tax purposes) to the different Transferred Assets as set forth in
Schedule 3.1., pursuant to Section 1060 of the Internal Revenue Code of
1986, as amended, and the Treasury Regulations promulgated thereunder
(hereinafter, the "Code").  Seller will agree to Buyer's proposed
Allocation Statements.

          Buyer and Seller shall each file all income, franchise and other
Tax Returns (as defined below), and execute such other documents as may be
required by any governmental authority, in a manner consistent with the
Allocation Statements.  Buyer shall prepare the Form 8594 under Section
1060 of the Code based on the Allocation Statements and deliver such form
and all documentation used in the preparation and support of such
Allocation Statements and form (including, but not limited to, appraisals)
to the Seller within 30 days after finalization of the Allocation
Statements.  The Buyer and the Seller agree to file such form with each
relevant taxing authority and to refrain from taking any position
inconsistent with such form or Allocation Statements.

          Notwithstanding the above provision, Buyer agrees to indemnify
and hold Seller harmless from and against any and all liability for Taxes
resulting from any reallocation of the Purchase Price that differs from the
estimated allocation as set forth in Schedule 3.1.  For purposes of
calculating the amount of any Taxes in the preceding sentence, it shall be
assumed that such Taxes are payable at the highest effective statutory
corporate income tax rates that could apply to Seller, as applicable, for
the relevant period.

          Section 3.2.     Filing of Returns and Payment of Taxes.
Seller shall prepare and file, or cause to be prepared and filed, with the
appropriate authorities all Tax (as defined below) returns, reports and
forms (herein "Tax Returns") and shall pay, or cause to be paid, when due
all Taxes relating to the Transferred Assets attributable to any taxable
period which ends on or prior to the Closing Date (herein "Pre-Closing Tax
Period").  Buyer shall prepare and file, or cause to be prepared and filed,
with the appropriate authorities all Tax Returns, and shall pay, or cause
to be paid, when due all Taxes relating to the Transferred Assets
attributable to the period which is not part of the Pre-Closing Tax Period.
If, in order to properly prepare its Tax Returns or other documents
required to be filed with governmental authorities, it is necessary that a
party be furnished with additional information, documents or records
relating to the Transferred Assets, both Seller and Buyer agree to use
reasonable efforts to furnish or make available such information at the
recipient's request, cost and expense provided, however, that no party
shall be entitled to review or examine the Tax Returns of any other party.

          Section 3.3.     Refunds and Credits.

          Any refunds and credits attributable to the Pre-Closing Tax
Period shall be for the account of the Seller and any refunds and credits
attributable to the period which is not part of the Pre-Closing Tax Period
are for the account of the Buyer.

          Section 3.4.     Transfer Taxes.

          All transfer, documentary, sales, use, registration, value-added
taxes and any similar taxes (including real estate transfer taxes) incurred
in connection with this Agreement and the transactions contemplated hereby
shall be borne by Buyer, in addition to the consideration in Section 1.3.
To the extent legally able to do so, Buyer and Seller shall cooperate with
each other to obtain exemptions from such taxes, including the value added
tax and the preparation of necessary documentation, provided that neither
party shall be obligated to seek any exemption that would require any
governmental audit of its books and records.

          Section 3.5.     Tax Definitions.

          For purposes of this Agreement, "Tax or Taxes" means all taxes,
imposts, duties, withholdings, charges, fees, levies, or other assessments
imposed by any governmental or taxing authority, whether domestic or
foreign, including but not limited to, income, gross receipts, excise,
property, sales, use, transfer, conveyance, payroll or other employment
related, license, ad valorem, value added, withholding, social security,
national insurance (or other similar contributions or payments), franchise,
estimated severance, stamp taxes, taxes based upon capital stock or net
worth and other taxes (including interest, fines, penalties, or additions
attributable to or imposed on or with respect to, any such taxes, charges,
fees levies or other assessments).

Article IV.      Other Matters.

          Section 4.1.     Consents and Subcontracted Work.     Seller and
Buyer shall use reasonable efforts to obtain, in a reasonable amount of
time and no later than four months after the Closing Date unless
impractical, all requisite consents to assignments and novations, as the
case may be, of all of the Transferred Assets and the Assumed Liabilities.
The Parties will cooperate and use reasonable efforts in obtaining such
consents and novations in accordance with the provisions of this Agreement.
The material consents to assignment that have been identified at this time
are listed on Schedule 4.1.  If any such required consents cannot be
secured without the incurring of any significant additional costs, the
Parties shall enter into such other arrangements with respect to the
underlying rights and obligations as shall permit Buyer to perform the
obligations of Seller thereunder, as a subcontractor or otherwise, and
Buyer to obtain the sole benefit thereof (the "Subcontracted Work"); and
until the requisite consents are obtained, such obligations shall not be
deemed to be included in the Assumed Liabilities and nothing contained
herein shall be deemed to constitute a breach of the contract underlying
such rights and obligations.  Buyer agrees to diligently perform and
discharge the obligations of Seller in connection with the Subcontracted
Work; and if and to the extent that consents to assignment are obtained
after the Closing Date, Buyer agrees that such obligations shall no longer
be considered to be Subcontracted Work, but shall instead be deemed to be
Assumed Liabilities for all purposes of this Agreement.

          The Seller hereby transfers to the extent it has the legal right
to do so and subject to the applicable license agreements with the
licensors, its royalty-free usage rights to the shrink-wrap personal
computer software (also known as conditions of use software) being used in
the normal course of the Seller's Zurich laser chip production by the
Employees, if such software is installed as of March 7, 1997 on the
computers which are among the Transferred Assets. If such software
copyrights are owned by the Seller, Seller's license terms and conditions
continue to apply.

          Section 4.2.     Employees and Employee Benefits.

          (a)  Schedule 4.2.A. contains a list of some of the individuals
employed by the Seller at the date hereof (including active employees and
employees who are on leave of absence; sick leave or disability leave)
(herein the "Employees").

          (b)  The employment relations of the Employees are assumed by the
Buyer, together with all rights and obligations, from the date of the
Closing.

          (c)  The Buyer agrees to use reasonable efforts to provide
comparable benefits.  It being understood that the Buyer may not be in a
position to provide all the ancillary benefits currently provided by the
Seller to the Employees.  The Buyer has  knowledge of  the Seller's Swiss
Staff Member Manual.  The Seller and the Buyer shall comply with their
respective obligations under Article 333 of the Swiss Code of Obligations.
However, the Seller shall not continue to provide or ensure these benefits
after the Closing Date to the Buyer's Employees.  The Buyer assumes all
liabilities for the failure to perform.  The Buyer shall provide for the
appropriate amendments in the employment agreements.

          (d)  The Buyer agrees as promptly as is practicable from the
Closing Date to establish a new defined occupational pension plan (the
"Buyer's Plan") to provide the transferred Employees with pension benefits
that are at least substantially comparable with the benefits that are
provided to such Employees under the Seller's two pension benefit plans
according to Exhibit E.  The Buyer's Plan shall provide for the
participation of such Employees therein as of the Closing Date, and provide
that in applying any length of service requirement for participation or
vesting and in determining the benefits, each such Employee shall be
credited with prior service as shown in the records of the Seller,
according to the Seller's rules for service credit, and with the eligible
compensation under the Seller's plan's during the period.  The Seller shall
provide the Buyer the documents listed in schedules to Exhibit E to
establish and administer the Buyer's plan with respect to each Employee's
pension benefits, eligible compensation and service prior to the Closing
Date.

          (e)  For the free movement of capital between the pension funds
and for the partial liquidation of a pension fund the Parties agree to
comply with the Free Movement Statue (Freizugigkeitsgesetz).  The assets
shall be calculated according to the Swiss law (BVG and FZG).  According to
Article 23 (1) of the FZG, the plan of distribution shall be approved by
the official supervisory body.

          (f)  These pension provisions are more fully set forth in Pension
Matters, Exhibit E and its schedules and attachments. Upon transfer of the
Transferred Pension Assets (as defined in Exhibit E) to the Buyer's Plan
(as defined in Exhibit E) the Buyer's Plan shall assume all liabilities of
the Seller's Plans for the pension benefits for the Employees and such
transfer shall be in full discharge of all obligations of the Seller's
Plans for the pension benefits.

          (g)  Buyer shall be responsible for liabilities with respect to
all employment matters concerning the employment of the Employees after the
Closing, including the termination of any Employees by Buyer after the
Closing and damages or settlements arising out of any claims of wrongful or
illegal termination, and for complying with the requirements of all
applicable laws with respect to any such termination.

          (h)  Buyer agrees to employ the Employees in the Zurich,
Switzerland area, utilizing the Transferred Assets, for at least twenty-
four months following the Closing.

          (i)  For three years from the date of this Agreement, Seller will
not solicit for employment or employ in any capacity any individual who,
within 12 months prior to the date of new hire, has been an Employee
transferred as part of this Agreement.  For three years from the date of
this Agreement, Buyer shall not solicit for employment or employ in any
capacity any individual who, within 12 months prior to the date of new
hire, has been an employee of Seller or its Affiliates working or employed
at Seller's Zurich laboratory, other than Employees.

          (j)  Buyer shall be responsible for obtaining any necessary work
permits for any Employee required under applicable law, as of and after the
Closing.  Seller shall reasonably cooperate with Buyer on such matters.
Seller will provide Buyer with a letter which describes the transfer of the
Employees in the form as has been agreed between the Swiss counsel of the
Seller and Buyer on the Closing Date.

          (k)  Subject to the Employees' employment agreements or the terms
of any new employment contract between such Employees and Buyer, and
applicable law, the Buyer retains its right  to terminate any Employee for
cause.  Nothing in this Agreement shall be deemed to convey any rights to
any Employee as a third party beneficiary of any obligation of Buyer to
Seller hereunder.

          Section 4.3.     Leased Property.     The Swiss representatives
of the Buyer and the Seller have negotiated a Seller Lease in the form of
Exhibit D, under Swiss law, for the lease to Buyer from Seller of real
estate following the Closing.

          Section 4.4.     Further Action.     Each of the Parties agrees
to execute and deliver after the Closing Date such other documents,
certificates, agreements and other writings and to take such other actions
as may be necessary, in the opinion of counsel, in order to consummate or
implement expeditiously the transactions contemplated hereby.  In addition,
Seller agrees, promptly upon the request of Buyer, and at no additional
expense to Seller, other than the expenses associated with the preparation
of appropriate instruments of assignment, to take all actions reasonably
requested by Buyer to perfect the transfer to Buyer of the Transferred
Assets.  The March 1997 payroll for Employees will be paid to the Employees
by Seller under its standard Swiss monthly payroll system. No later than
April 30, 1997, Buyer will pay Seller's invoice for Buyer's proportionate
share of the March payroll, including any applicable social security,
pension plan contributions, and similar sums. Buyer's invoiced payment will
equal a sum calculated by multiplying the total monthly payroll for the
Employees by a fraction, (1) the numerator of which will be the number of
days remaining in March after the Closing Date and (2) the denominator of
which will be 31. (Hypothetically, if the Closing Date is March 10, the
fraction would be 21/31).  Seller shall be responsible for all accrued,
unused vacation through March 10,1997, with respect to the Employees and
shall pay to Buyer on or prior to March 30,1997, an amount equal to the
value of Seller's salary due for such accrued unused vacation.

          Section 4.5.     Transitional Services Agreement.     The Swiss
representatives of the Buyer and the Seller have negotiated a Transitional
Services Agreement in the form of Exhibit C, under Swiss law, to handle
services to be provided to the Buyer by the Seller after the Closing.

          Section 4.6.     Liens.     Within thirty days after notice to
Seller of attachment, Seller shall clear all material title liens or
encumbrances upon title attaching to the Transferred Assets after the
Closing Date which arise due to acts or failures to act of Seller prior to
or on the Closing Date.  If Seller is unable to clear all material title
liens or encumbrances upon title within thirty (30) days after notice,
Seller shall complete any action necessary to provide Buyer with materially
unencumbered title to the Transferred Assets.  In the event that Seller
shall fail to take such action within the time periods specified in this
Section 4.6, to clear such liens and encumbrances under Swiss law, Buyer
shall have the right to take such action as it deems reasonably necessary
to clear such liens or encumbrances upon title and to obtain reimbursement
for its out-of-pocket costs, plus interest at the simple rate of 10% per
annum, from Seller.

          Section 4.7.     Relocation.     The Buyer and Seller agree that
the Transferred Assets are being prepared and positioned for a sale and a
physical relocation out of their current facilities.  No representations or
characterizations as to the Seller's ordinary course of business, the
maintenance condition or operation of the Transferred Assets or the results
to be obtained from those assets are being made.

          Section 4.8.     Due Diligence.     This sale includes the
transfer, by operation of and subject to Swiss law, of the Employees,
performing substantially the same work as that being performed by those
employees for the Seller.  The Buyer has engaged in such due diligence
effort as it has deemed appropriate prior to signing this Agreement.  The
sale of the Transferred Assets is based upon the results of that due
diligence and there has been no reliance upon the representations or
statements of Seller, to Uniphase Corporation or Buyer, other than the
written representations set forth in the Seller's representations in
Article VI of this Agreement, or in the Intellectual Property Agreements,
the Transitional Services Agreement or the Seller Lease.

          Section 4.9.     Buyer Financial Statements.     Seller will
cooperate with Buyer and Buyer's auditors to permit Buyer and Buyer's
auditors to timely prepare and file financial statements relating to the
Transferred Assets, prepared by the Buyer in accordance with United States
generally accepted accounting principles and the rules and regulations of
the Securities and Exchange Commission.

Article VI.     Representations and Warranties of Seller.

          Seller hereby represents and warrants to Buyer as follows:

          Section 6.1.     Incorporation.     Seller is a duly incorporated
and validly existing corporation in good standing under the laws of the
State of New York, with all requisite corporate power and authority to own
its properties and conduct its business, and is duly qualified in each
jurisdiction in which its ownership of property requires such qualification
except where the failure to so qualify would not have a material adverse
effect upon the Transferred Assets or the ability of Seller to perform its
obligations hereunder.

          Section 6.2.     Authority.     Seller has the requisite
corporate power and authority to execute and deliver this Agreement, the
Seller Lease and Assumption Agreement, the Bill of Sale, the Transitional
Services Agreement and the Intellectual Property Agreements, and to perform
its obligations under each of the foregoing.  Each of this Agreement, the
Seller Lease and Assumption Agreement, the Bill of Sale, the Transitional
Services Agreement, and the Intellectual Property Agreements, has been duly
and validly authorized, executed and delivered by Seller and constitutes
the valid and binding agreement of Seller in accordance with its respective
terms.  No other corporate proceedings on the part of Seller are necessary
to authorize this Agreement, the Intellectual Property Agreements, the
Seller Lease and Assumption Agreement, the Bill of Sale, and the
Transitional Services Agreement, and the transactions contemplated by any
of the foregoing.

          Section 6.3.     No Conflict.     The execution and delivery by
Seller of this Agreement, the Intellectual Property Agreements, the Seller
Lease and Assumption Agreement, the Bill of Sale, and the Transitional
Services Agreement does not, and the performance by Seller of its
obligations hereunder and thereunder will not:

          (a)  conflict with, or result in a breach of, any of the
provisions of its Certificate of Incorporation or By-Laws;

          (b)  breach, violate or contravene any applicable law, rule or
regulation of the United States or any political subdivision thereof, or
Switzerland or any political subdivision thereof, or any order, writ,
judgment, injunction, decree, determination or award, or create any right
of termination or acceleration or encumbrance that, in the aggregate would
have a material adverse effect on the Transferred Assets; or

          (c)  conflict in any respect with, or result in a breach of or
default under, any contract, license, franchise, permit or any other
agreement or instrument to which Seller is a party or by which it or any of
the Transferred Assets may be bound that in the aggregate would have a
material adverse effect on the Transferred Assets (except for agreements
and instruments that require the consent or approval of a third party for
the transactions contemplated by this Agreement).

          Section 6.4.     Governmental Consents - Seller.     Other than
as set forth on Schedule 6.4, no material consent, approval or
authorization of, or designation, declaration or filing with, any
governmental agency or authority on the part of Seller is required in
connection with the execution or delivery by Seller of this Agreement, the
Intellectual Property Agreements, the Seller Lease, the Assumption
Agreement, the Bill of Sale, or Transitional Services Agreement or the
consummation by Seller of the transactions contemplated by any of the
foregoing other than the authorization in connection with the Seller Lease,
according to the Swiss Lex Friedrich to be obtained and other than the
future Swiss Pension Transfer Agreement.

          Section 6.5.     No Broker.     Seller has engaged no
corporation, firm or other person who is entitled to any fee or commission
as a finder or a broker in connection with the negotiation of this
Agreement or the consummation of the transactions contemplated hereby, and
Seller shall be responsible for all liabilities and claims (including costs
and expenses of defending against same) arising in connection with any
claim by a finder or broker that it acted on behalf of Seller in connection
with the transactions contemplated hereby.

          Section 6.6.     Title to Personal Property.      Seller has good
and marketable title to all tangible personal property listed on Schedules
1.1.A., 1.1.B., 1.1.C., hereto, free and clear of any material liens or
encumbrances.

          Section 6.7.     Actions, Suits, Proceedings.     Other than as
set forth on Schedule 6.7, there are no actions, suits, or proceedings
pending or, to Seller's knowledge, threatened against the Transferred
Assets, at law or in equity, including any administrative proceedings with
any regulatory authority; and no third party claims have been asserted
against Seller or its affiliates with respect to the Transferred Assets.
There is no existing default by Seller or, to the knowledge of Seller, any
of its affiliates with respect to any judgment, order, writ, injunction or
decree of any governmental authority or arbitrator which materially
adversely affects the Transferred Assets.

          Section 6.8.     No Rights In Others To Transferred Assets.
Neither Seller nor any affiliate of Seller is party to any outstanding
contracts or other arrangements giving any person any present or future
right to require Seller to transfer to any person any ownership or
possessory interest in, or to grant any lien on, any of the Transferred
Assets, other than pursuant to this Agreement.

          Section 6.9.     Contracts.     Schedule 1.4.A. contains a true
and complete list of all material customer or vendor contracts constituting
the Transferred Assets.  Seller has performed or is performing all material
obligations required to be performed by it under such contracts and is not
(with or without notice, lapse of time or both) in breach or default in any
material respect thereunder; and, to the knowledge of Seller, no other
party to any of such contracts is (with or without notice of time or both)
in breach or default in any material respect thereunder.

           Section 6.10.     Licenses and Permits.     Seller or its
affiliates have the licenses and permits and other governmental
authorizations and approvals as set forth on Schedule 6.10.  All such
licenses and permits held by Seller which are material to the use of the
Transferred Assets are valid and in full force and effect.  Buyer has made
its own investigation of such matters and is responsible for obtaining such
regulatory approvals for its operations after the Closing.  To the personal
knowledge of the four most senior level executives among the Employees, as
expressed to the Buyer prior to the signing of this Agreement during due
diligence, they do not believe the operation of the Transferred Assets, as
operated by the Seller immediately prior to the date of this Agreement,
violated any applicable law.

          Section 6.11.     Employee Union.      No union organizing
activities are in progress or, to Seller's knowledge, threatened at
Seller's facilities concerning the Employees.

          Section 6.12.     Exclusive Warranties.     Except for the
express representations and warranties made by Seller in this Article VI,
Seller makes no representation or warranty, express or implied, concerning
the Transferred Assets, it being specifically understood by Buyer that,
except for the express warranties set forth in this Article VI, the
Transferred Assets are being sold "AS IS" in all respects.  SELLER
SPECIFICALLY DISCLAIMS ANY WARRANTY OF MERCHANTABILITY OR SUITABILITY OR
FITNESS FOR ANY PARTICULAR PURPOSE OF BUYER'S, WHETHER OR NOT SELLER HAS
BEEN MADE AWARE OF ANY SUCH PURPOSE.  SELLER SHALL NOT BE RESPONSIBLE FOR
ANY INDIRECT, SPECIAL OR CONSEQUENTIAL DAMAGES OF BUYER WHATSOEVER,
INCLUDING LOSS OF PROFITS OR GOODWILL, IN CONNECTION WITH THIS TRANSACTION.

          Section 6.13.     Book Value.     Seller makes no representations
or warranties as to the book value, for tax or for accounting purposes, of
any of the Transferred Assets.

Article VII.     General.

          Section 7.1.     Survival of Representations and Warranties.
All representations and warranties made by the Parties in this Agreement or
any agreement contemplated by this Agreement shall survive the Closing for
a period of twenty-four (24) months after the Closing Date, provided, that,
the representations and warranties in respect of Taxes shall survive the
Closing Date until the applicable period of limitation on assessment or
refund of any relevant Tax has expired.

          Section 7.2.     Limitation of Liability.     Unless the
application of this Section is specifically excluded in writing,
notwithstanding anything to the contrary set forth in this Agreement, the
Bill of Sale, the Seller Lease, the Assumption Agreement, the Transitional
Services Agreement, or the Intellectual Property Agreements, Seller shall
not be liable hereunder or thereunder for any amounts with respect to the
breach of a representation and warranty unless and until such amounts shall
exceed in the aggregate amount $250,000 (the "Limitation Amount"), in which
case Seller shall only be liable with respect to the excess over the
Limitation Amount.  In addition, in no event shall Seller's liability with
respect to the breach of representations and warranties exceed $11,000,000
in the aggregate.

          Section 7.3.     Public Announcements.     Under Article 181(2)
of the Swiss Code of Obligations the Seller may be jointly and severally
liable to third parties for its transferred business activities for two
years from a notification or publication date of this transaction following
the Closing.  The Parties shall each individually have the right to decide
whether to publicize the transaction of the assets and/or to inform
personally or by circular letter the relevant creditors, customers and
vendors.  Any disclosures in connection with commercial relationships shall
not reveal the Purchase Price of this Agreement.  Notwithstanding the
foregoing, each Party shall have the right, in its sole discretion, to make
such disclosures as it may deem necessary or advisable to any governmental
agencies or instrumentalities or regulatory bodies.

          Section 7.4.     Costs.     Each Party shall be responsible for
the costs and expenses incurred by it in the negotiation, execution and
delivery of this Agreement and, except as otherwise provided elsewhere in
this Agreement, the consummation of the transactions contemplated hereby.

          Section 7.5.     Bulk Sales.     Buyer and Uniphase Corporation
hereby waive compliance with any applicable bulk sales or similar laws in
the United States or Swiss jurisdictions.  Buyer intends to discharge the
Assumed Liabilities in accordance with their terms and the Buyer agrees
that the Seller shall have no liability for any failure of Buyer to
discharge the Assumed Liabilities in accordance with their terms.

          Section 7.6.     Modification and Waiver.     No modification or
waiver of any provision of this Agreement and no consent by any Party
hereto to any departure therefrom shall be effective unless in a writing
referencing the particular article of this Agreement to be modified or
waived and signed by a duly authorized officer of each Party, and the same
will only then be effective for the period and on the conditions and for
the specific instances and purposes specified in such writing.

          Section 7.7.     Governing Law.     This Agreement has been
delivered at and shall be deemed to have been made at Armonk, New York, and
shall be interpreted, and the rights and liabilities of the parties hereto
determined, in accordance with the laws of the State of New York applicable
to agreements executed, delivered and performed within such State, without
regard to the principles of conflicts of laws thereof, provided, however,
that the Parties agree to apply and comply with all mandatory provisions of
the laws of Switzerland applicable to this transaction as a matter of Swiss
public policy, which provisions are applicable regardless of the Parties
choice of law.

          As part of the consideration for value this day received, each of
the Parties hereby consents to the jurisdiction of any state or federal
court located within the county of Westchester in the State of New York.
Each of the Parties hereby:  (i) waives trial by jury, (ii) waives any
objection to venue of any action instituted hereunder and (iii) consents to

          UNIPHASE LASER ENTERPRISE AG, a Swiss AG ("Buyer"), and
               INTERNATIONAL BUSINESS MACHINES CORPORATION,
                    a New York corporation ("Seller").

          WHEREAS Buyer, Seller and Uniphase Corporation have entered into
a Purchase Agreement dated as of March 10, 1997 (the "Purchase Agreement"),
providing for, among other things, the purchase by Buyer of the Transferred
Assets from Seller; and

          WHEREAS, in conjunction with such purchase, Seller desires to
sell, transfer, convey, assign and deliver to Buyer all of Seller's rights,
title and interest in and to the Assumed Liabilities, which form part of
the Transferred Assets.

          NOW, THEREFORE, in consideration of the mutual convenants and
undertakings contained herein, and subject to and on the terms and
conditions herein set forth, the parties hereto agree as follows:

shall have such meaning throughout this Agreement.

          2.   Other Terms.  All capitalized terms not otherwise defined
herein shall have the meanings ascribed thereto in the Purchase Agreement.
Nothing contained herein shall be deemed to alter or amend the terms and
provisions of the Purchase Agreement, and in the event of any conflict
between the terms and provisions of this Agreement and the Purchase
Agreement, the terms and provisions of the Purchase Agreement shall be
deemed to govern and be controlling in all circumstances.

          3.   Assignment.  Seller hereby irrevocably sells, transfers,
conveys, assigns and delivers to Buyer all of its right, title and interest
in and to the Assumed Liabilities.

          4.   Assumption.  Buyer does hereby accept such sale, transfer,

          6.   Noncontravention.  Pursuant to Section 4.1 of the Purchase
Agreement, certain of the Assumed Liabilities may require the consent of
third parties to any assignment.  Such assignments to Buyer are made
subject to the obtaining of such consents and shall be effective as of the

interpreted, and is not intended to be interpreted, as any action taken by
Seller that would be contrary to the terms and conditions of any contract
requiring the consent of any third party to such assignment.  Buyer and
Seller shall fully cooperate with each other in an attempt to obtain such
consents, as set forth in the Purchase Agreement.

          7.   Notices.  All notices and other communications hereunder

circumstance, shall, for any reason, be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provision hereof, and this
Agreement shall be construed as if such invalid, illegal or unenforceable
provision had never been contained herein.

          12.  Third Party Actions.  Seller and Buyer hereby agree to
cooperate in defending or prosecuting any claims or litigation relating to
the transfer of title as provided herein, and to make available and furnish

powers of attorney and other documents, and do all such other acts and
things as may be necessary to more fully convey and assign to buyer, or its
successors or assigns, all right, title and interest in and to the Assumed
Liabilities conveyed, assigned and transferred to or acquired by Buyer
pursuant to this Agreement, including, without limitation, filings with any
governmental entity, authority or instrumentality, domestic or foreign.

binding Agreement when one or more of the counterparts have been signed by
each of the parties and delivered to the other party.




IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be

                                    and

                           ____________________
       
       
       Whereas, the Lessor wishes to sell Uniphase Corporation and  to  the
       Lessee,  and Uniphase Corporation and the Lessee wishes to  purchase
       from  the  Lessor the Transferred Assets as defined in the  Purchase
       Agreement (as defined below)
       
       Whereas,  the Lessee, Uniphase Corporation and the Lessor  for  this
       purpose  have  entered into purchase agreement dated  of  even  date
       herewith (hereinafter referred to as the "Purchase Agreement"), and
       
       Whereas, the Lessor and the Lessee have entered into a Lease
       Agreement for certain offices, cleanroom, wet and dry laboratories,
       and common rooms in the premises of Saumerstrasse, Ruschlikon,
       Switzerland, owned by the Lessor, during a transitional period
       following the execution of the Purchase Agreement (hereinafter
       referred to as the "Lease Agreement"); and

       Whereas, the Lessor and the Lessee intend, during such transitional
       period following the execution of the Purchase Agreement to provide
       and receive partly on mandatory and partly on optional basis
       respectively certain basic support and administrative services; and

       Whereas, on the other hand, the Parties agree that there are
       certain services which Lessor provides for its departments, which
       will not be available to the Lessee.
       
       Now therefore in consideration of the mutual covenants and
       undertakings herein contained the parties hereto agree as follows:


1. Subject Matter of the Agreement

       1.1.    The subject matter of the Services Agreement is to set
           forth the conditions under which Lessor will provide services
           to the Lessee for the term of the Lease Agreement. In this
           respect it is to be distinguished between:
       
           a)    Such services which the Lessee has the duty and the
             right to make use of and the Lessor has the obligation to
             provide for the term of the Lease Agreement (hereinafter
             referred to as "Mandatory Services"); and
           
           b)    such services which the Lessee may, at its option, take
             advantage of (hereinafter referred to as "Optional
             Services").
       
       1.2.    The Lessee acknowledges and agrees that the Lessor is
           offering no services other than those hereinbefore mentioned
           and which are hereinafter defined as Mandatory and Optional
           Services.


2. Mandatory Services

       2.1.    Mandatory Services including specific prerequisites and
           conditions of the same are set forth in Schedule 1.
       
       2.2.    The Lessor undertakes with the execution of the Services
           Agreement to provide the mandatory services in accordance with
           the remaining provisions of this agreement for the entire term
           of the Lease Agreement.
       
       2.3.    The Contracting Parties agree that according to the
           provisions of Section 9.7. and 10.1. of the Lease Agreement
           they are obligated to make use of or to carry out the Mandatory
           Services for as long as the term of the Lease Agreement lasts.
       
3. Optional Services

       3.1.    The Optional Services which may be required by the Lessee
           for the term of the Services Agreement are set forth in
           Schedules 2 and 3.
       
       3.2.    Schedule 2 sets forth such Optional Services including the
           specific prerequisites and conditions which the Lessee may
           request in writing from the Lessor (hereinafter referred to as
           "Optional Services Category 1").
       
       3.3.    Schedule 3 sets forth a general description of such
           services which the Lessor is offering to the Lessee whereby the
           prerequisites and the conditions have not been set forth
           (hereinafter referred to as "Optional Services Category 2").
       
          In the event that the Lessor wishes to take advantage of any
           such individual service, the Parties shall enter into an
           additional agreement regarding such services. Any such
           additional agreement shall supplement the Services Agreement by
           way of a Schedule thereto. As far as such additional agreement
           does not foresee any special regulation, the rules of the
           Services Agreement shall be applicable.
       
       3.4.    The Lessee acknowledges and agrees that the Lessor shall
           carry out all such Optional Services as shall be required
           according to the availability of the same whereby the Lessor,
           in using its resources, may primarily take into account its own
           needs.
       
       3.5.    The Lessee is aware that in the event the Lessee calls
           upon third parties for the purpose to carrying out the Services
           of model shop, electronic services, shared tools, cafeteria,
           self-service model shop (as referenced in Optional Services
           Category 1. Schedule 2), the provision thereof shall occur
           outside the Site. The facilities of the Lessor cannot be used
           for this purpose.
       

4. Extent and Provision of Services

       4.1.    The Lessor agrees to provide the services under this
           Services Agreement with the appropriate care and diligence.
       
          The standard of assistance on the part of the Lessor is to be
           measured with respect to the contents as well as the standard
           of care, in accordance with the past services of the Lessor of
           the particular service within its enterprise.
       
          The Lessee confirms that as a result of the level of knowledge
           of such employees as it has assumed, it has adequate knowledge
           of the standard of the previous provision of services.
       
       4.2.    The Lessor is entitled to call upon third parties for the
           purpose of carrying out the services hereunder.
       

5. Place of Performance

       The place of performance of all of the services provided for in the
       Services Agreement is in the Leased Premises according to the Lease
       Agreement.


6. Deadlines

       6.1.    Inasmuch as no distinct rule has been agreed to in
           writing, the Lessor shall provide the services during working
           days only, from Monday to Friday, from 8.00 a.m. till 5.00
           p.m., according to the availability of the resources pursuant
           to Section 3.4. hereof.
       
       6.2.    In the event that circumstances beyond its own control,
           namely the failure of third party suppliers to observe
           deadlines should lead to postponements on the part of the
           Lessor, then deadlines shall be correspondingly postponed.

7. Term of the Agreement

       7.1.    The term of the Services Agreement shall begin on the
           Closing Date of the Purchase Agreement and shall remain in
           force for as long as the Lease Agreement shall remain in
           effect.
       
       7.2.    Upon termination of the entire Lease Agreement, the
           Services Agreement shall terminate automatically.
       

8. Early Termination of Individual Service Requirements

       8.1.The Mandatory Services have been agreed to for the entire term
           of the Services Agreement and the Lease Agreement. Except in
           case of the early termination of the entire Lease Agreement, it
           may not be terminated early by either the Lessor or the Lessee.
       
       8.2.Any item of the Optional Services Category 1 may be terminated
           by both Parties by means of written notice with a notice period
           of 60 days effective as of the end of the calendar month next
           following the expiration of the notice period.
       
          The Lessor shall remain obligated for the remaining term of
           this agreement to provide Optional Services Category 1
           according to the remaining provisions of the Services
           Agreement.
       
       8.3.With respect to the termination of the provision of Optional
           Services of Category 2 the same shall be governed by the
           relevant terms of the individual supplementary agreement
           entered into with respect thereto.
       

9. Duty to provide Information on the Part of the Lessee

           limitation in Section 10.4. incurred by the Lessee as a result
           of the breach of the Services Agreement by the Lessor. In no
           event will the Lessor be liable to the Lessee for loss of
           revenue or profits or any indirect damages including claims of
           third parties.
       
       10.3.   Should the subject matter of the Services Agreement be the
           provision of products which the Lessor for its part is
           obviously provided with by a third party, the Lessor shall only
           be liable to the Lessee to the extent that the third party
           supplier has provided the Lessor with a warranty and is liable
           to the Lessor.
       
       10.4.   If damages do not exceed SFr. 5'000.-- per event, the
           Lessor shall not be liable. If damages exceed SFr. 5'000.-- the
           Lessor's total liability for such event will be limited to SFr.

           during the term of the Services Agreement will not exceed SFr.

           personal injury.

           events (including, but not limited to, war, conditions or
           events of nature, government acts or regulations, civil
           disturbances, work stoppage, power failures, failure of
           telephone lines and equipment, fire and flood) beyond the
           control of the Lessor which rendered performance by it
           hereunder impossible.
       
       10.6.   Any further liability or warranty is excluded.

       The Parties will agree to negotiate intellectual property rights
       for intellectual property that arises from the result of the work
       performed by Lessor for the Lessee hereunder under Optional
       Services Category 1 / Model Shop and Electronic Services prior to

           invoiced at the end of each month. Unless the Lessee does not
           react within thirty days from the receipt of the invoice, the

           in accordance with the laws of Switzerland.
       
       14.2.   In case any provision of the Services Agreement shall be
           held invalid, illegal or unenforceable, the validity, legality

           of  the  remuneration  for the use of  the  Leased  Premises  is

           Lessee  shall pay a monthly rent of SFr. 90.-- per  meters squared
           for  the use  of the offices and of SFr. 145.-- per meters squared

           increases  of  at least 5 points, the Lessor may  once,  at  the

           rents according to the following formula:
       
           Increase in %:

                             contract      
       

       5.6.The agreed initial rents cannot be decreased.

                        Exhibit E:  Pension Matters

Final

Paragraph 1.       The Buyer's Plan.

          a.     The Buyer agrees as promptly as is practicable after the
Closing Date but in any event within 90 days thereafter to (i) establish a
new defined occupational pension plan or amend an existing plan (the
"Buyer's Plan") to provide Employees with pension benefits that are at
least substantially comparable with the benefits that are provided to
Employees under the Seller's two applicable pension benefit plans as of the
Closing Date (the "Seller's Plans"), (ii) provide for the participation of
Employees therein as of the Closing Date, and (iii) provide that in
applying any length of service requirement for participation or vesting,
and in determining an Employee's benefits under the Buyer's Plan, such
Employee shall be credited with prior service accruing from and after such
Employee's "Service Reference Date" as shown in the records of the Seller,
according to Seller's rules for service credit, and with such Employee's
eligible compensation under the Seller's Plan during that period.  The
Seller shall provide the Buyer with true, correct and complete copies of
all documents, amendments, instruments, employee communications and records
related to Seller's Plans and required to establish and administer the
Buyer's Plan with respect to each Employee's pension benefits, eligible
compensation and service prior to the Closing Date.

          b.     The Buyer further agrees that the Buyer's Plan shall
contain an irrevocable provision prohibiting the Buyer or any Affiliate of
or successor to the Buyer from receiving a reversion of all or any portion
of the Transferred Pension Assets.  The Buyer's Plan shall also provide
that upon the termination of Buyer's Plan and after payment of all
liabilities under Buyer's Plan, the plan trustee or its successor or
transferee shall transfer any remaining Transferred Pension Assets to a
separate trust established by the Buyer for the exclusive benefit of the
Employees provided that such trust shall not operate in a manner which
discriminates in favor of any highly paid Employees.

Paragraph  2.     Calculation of Transferred Assets.

          a.   Seller's Actuary is E.Wirz-Kaufmann.  Seller's Actuary shall
determine the proposed funds to be transferred (herein "Transferred Pension
Assets"), based on the assumptions used by the Seller's Actuary according
to the 1995 annual review of Seller's Plans reported to and approved by the
official supervisory board  ("Amt fur berufliche Vorsorge"), when
calculating the assets to cover the liability under Seller's Plans.


          b.  The Seller will entitle Seller's "Vorsorgefonds der IBM
Corporation, Forschungslaboratorium Zurich" to transfer the amount of
Swiss Francs  1,271,699 which are part of the Seller's contribution reserve
to the Buyer's Plan. The parties agree that this amount will be allocated
to the individual pension plan accounts in the Buyer's Plan of the eleven
(11) Employees who qualify for the Seller's Personalfursorgestiftung der
IBM Corporation, Forschungslaboratorium Zurich according to the partition
amounts set forth in Attachment 1.

          c.  The Parties agree that the six (6) Employees listed in
Attachment 2 (the "Six Employees") remain with Seller's Plans for 180 days
after the Closing Date (the "180 Day Period"). The Seller has the
obligation to, if necessary, amend or cause to be amended the rules and
regulations of Seller's Plans in order to allow the Six Employees to remain
with Seller's Plans for the 180 Day Period. The Buyer is responsible for
the payment of normal compensation to the Six Employees after the Closing
Date as long as they are employed with Buyer. The Buyer further agrees to
pay the normal pension fund premiums as long as such Employees are employed
with Buyer until the effective date of retirement. If at any time during
the 180 Day Period any of the Six Employees applies for early retirement,
the appropriate application shall be made in writing to the
"Personalvorsorgestiftung der IBM Corporation, Forschungslaboratorium
Zurich". Such retiring Employees (the "Retiring Employees") will remain
with Seller's Plans. Seller shall, or shall cause any of Seller's Plans to
pay, or cause to be paid, the pension payments as set forth in the rules
and regulations of Seller's Plans with respect to the Retiring Employees.
If certain of the Six Employees do not apply for early retirement within
180 days after the Closing Date (the "Non-Retiring Employees"), they will
be transferred to the Buyer's Plan. The Seller will transfer or cause to be
transferred 180 days after the Closing Date to the Buyer's Plan the amount
of Swiss Francs identified in Attachment 3 for each Non-Retiring Employee.
That amount will be part of the Seller's Plans and part of Seller's
contribution reserve. The parties agree that any such amount will be
allocated for the exclusive benefit of the Non-Retiring Employees to the
individual pension plan accounts in the Buyer's Plan for the respective Non-
Retiring Employee. Notwithstanding anything to the contrary, no pension
fund amounts for the Six Employees will be transferred to the Buyer, other
than as set forth in this section c. and section g.

          d.  The Seller will entitle the Seller's "Vorsorgefonds der IBM
Corporation, Forschungslaboratorium Zurich" to transfer in addition to the
amount mentioned in section (b.) the amount of Swiss Francs 328,301, which
is part of the Seller's contribution reserve to the Buyer's pension plan.

          e.  Buyer and Seller agree that no other obligations between the
parties will result as a consequence of the partial liquidation of the
Seller's Plans and contribution reserves and will present and support this
agreement to the official supervisory board.

          f.   At the Closing a Board resolution of the "Vorsorgefonds der
IBM Corporation, Forschungslaboratorium, Zurich" will be provided to the
Buyer which states that the obligations mentioned in subparagraphs b,c and
d of this Exhibit E will be implemented according to their terms.

          g. The Seller agrees that, ultimately, the Seller will transfer
to the Buyer's Plan the amounts required pursuant to this Exhibit E, if any
circumstance results in the Seller's Plans fund failing to transfer such
amounts, provided however that this payment from Seller be in compliance
with Swiss Law.



Paragraph  3.     Actions to Effect Pension Assets Transfer.     The Seller
and the Buyer shall promptly, after the Closing Date, effect the transfer
of the Transferred Pension Assets to the Buyer's Plan as contemplated by
this Exhibit E, and in compliance with applicable Swiss law.  The future
Swiss Pension Transfer Agreement shall govern such matters.  Such transfer
shall be in cash or, to the extent mutually agreed to by the Seller and the
Buyer, in kind.

Paragraph 4.   Verification by the Buyer.  The Buyer shall have the right
to appoint an independent actuary (the "Buyer's Actuary") for the purposes
of verifying the free portability calculation of the Transferred Pension
Assets, referenced in paragraph 2.a. herein, by the Seller's Actuary
(excluding the amounts agreed upon by Buyer and Seller set forth in
attachments 1 and 3 of this Exhibit E).  Such amount as certified by the
Seller's Actuary shall be conclusive and binding on the Seller and the
Buyer unless, within 60 days after the delivery of such certification by
the Seller's Actuary to the Buyer's Actuary (during which time such
supporting factual information as the Buyer's Actuary may reasonably
request shall be provided by the Seller's Actuary), the Buyer's Actuary
shall notify the Seller of its disagreement with such amount.  Subject to
the Swiss Pension Transfer Agreement and the procedures and terms and
conditions therein, if it exists at that time, if any such disagreement is
not resolved to the satisfaction of the Seller and the Buyer within 30 days
of the Seller's receipt of such notification (or within such longer period
as the Seller and Buyer shall mutually agree), either the Seller or the
Buyer may elect to have the calculation submitted for arbitration by a
third independent actuary mutually acceptable to the Seller and the Buyer,
who shall be entitled to the privileges and immunities of an arbitrator,
and whose determination shall be conclusive, final and binding and have the
force and effect of an arbitrable award, provided, however, that none of
the Seller, the Buyer, the Seller's Plans or the Buyer's Plan shall be
bound by any decision of such arbitrator that would cause such party to
violate law.  The arbitrator will apply the pension provisions set forth in
the Purchase Agreement and this Exhibit E for any matters in dispute
hereunder.  The expenses of the Seller's Actuary shall be borne by the
Seller, the expenses of the Buyer's Actuary shall be borne by the Buyer and
the expenses of any third actuary shall be borne equally by the Seller and
the Buyer.

Section 2.0 License Grants
          
2.1     Subject to Sections 2.5 and 2.9, IBM grants to LICENSEE and its
Subsidiaries, to the extent that it has a right to do so, a nonexclusive
right and license to use the Licensed Information to:  (i) make and have
made Licensed Products only at the Authorized Locations and sell such
products worldwide; (ii) to use and make any apparatus (other than the E2
prototype tool) required to manufacture Licensed Products only at the
Authorized Locations; and (iii) improve, modify and enhance the Licensed
Information and to use and incorporate any such improvements, modifications
and enhancements in the exercise of the license rights pursuant to clause
(i) and (ii) and Section 2.11 below.  Subject to the last sentence of
Section 2.3 hereof, the foregoing license rights shall include the right to
sell and distribute any product that includes a Licensed Product as a
component or subassembly thereof.  Providing IBM receives the payment
specified in Section 4.1, the license granted in this Section 2.1 with
respect to R-F Licensed Products shall be royalty-free and fully paid-up.
The license granted in this Section 2.1 with respect to R-B Licensed
Products shall be royalty-bearing as provided in Section 4.2.

2.2     Subject to licenses granted to third parties prior to the Effective
Date and a license retained by IBM for itself and its Subsidiaries to use,
copy, modify and distribute internally, IBM hereby transfers, assigns and
conveys to LICENSEE all of IBM's right, title and interest in and to those
computer programs used at the Facility and identified in Exhibit C-1
hereto.  IBM hereby grants to LICENSEE, to the extent it has a right to do
so, a nonexclusive, paid-up and royalty-free license under copyrights, or
other similar rights for computer programs, to use, execute, reproduce,
modify, and prepare derivative works based upon the additional computer
programs listed in Exhibit C-2, only at the Authorized Locations.

2.3     Providing IBM receives the payment specified in Section 4.1, IBM
hereby grants to LICENSEE a nonexclusive, paid-up and royalty-free license
under the Licensed Patents to make and have made R-F Licensed Products at
the Authorized Locations and to use, offer to sell, sell and import
R-F Licensed Products worldwide.  The foregoing license shall not extend to
any infringement of IBM patents not licensed hereunder resulting from the
combination of Licensed Products with other products not licensed herein.
The term of the license granted in this Section 2.3 shall be for a period
of five (5) years from the Effective Date, unless LICENSEE exercises the
option granted in Section 2.6 and makes the payment specified therein, in
which event the term of the license shall be extended to the date of
expiration of the last to expire of the Licensed Patents.

2.4     Except as specifically granted in this Section 2.0, no license or
other right is granted, either directly or indirectly, by implication,
estoppel or otherwise, to LICENSEE with respect to any patents or patent
applications, trademarks, copyrights, trade secrets, computer programs,
know-how, mask works or other intellectual property rights of IBM.

2.5     The license to have Licensed Products made by another manufacturer
granted in Sections 2.1 and 2.3 to LICENSEE shall only apply when the
specifications for Licensed Products were created by LICENSEE (either
solely or jointly with one or more third parties); and shall not apply to
any Licensed Products in the form manufactured or marketed by said other
manufacturer prior to LICENSEE furnishing said specifications.

2.6     IBM grants to LICENSEE an option to obtain a fully paid-up extension
of the term of the patent license granted in Section 2.3 with respect to
R-F Licensed Products to cover the period extending to the date of
expiration of the last to expire of the Licensed Patents.  This option may
be exercised at any time prior to five (5) years from the Effective Date by
LICENSEE paying to IBM the sum of nine million US dollars ($9,000,000) and
giving written notice of the exercise of the option in accordance with
Section 7. Communications.

2.7   LICENSEE hereby grants to IBM an irrevocable, worldwide, nonexclusive,
paid-up and royalty-free license under LICENSEE's Patents to make, have
made, use, offer to sell, sell and import R-F Licensed Products.  IBM shall
have no right to grant sublicenses under LICENSEE's Patents, except to its
Subsidiaries.

2.8     In the event that LICENSEE identifies in writing to IBM any patents
licensable by IBM which are necessarily infringed by the exercise of the
license granted in Section 2.1 with respect to R-F Licensed Products being
manufactured at the Facility on the Effective Date, and IBM, after a good
faith analysis, agrees with LICENSEE's position, then upon IBM's written
notification, Exhibit A shall be automatically amended to include such
additional patents without further charge to LICENSEE.  In the event that
IBM shall determine for any reason that such infringement will not occur as
to a licensable IBM patent, IBM shall thereafter be estopped from making
any claims of infringement against LICENSEE, its Subsidiaries or its
customers as to such IBM patent for any exercise by LICENSEE of its rights
under Section 2.1 above.

2.9     Notwithstanding anything to the contrary, the license granted in
Section 2.1 shall not include rights to use any designs or other
information which are used exclusively to manufacture products for IBM.

2.10  Subject to the restrictions limiting the license rights to Authorized
Locations, LICENSEE shall have the right to exercise any license rights
granted hereunder through any Subsidiary, and any reference in this
Section 2 and Section 3 below to LICENSEE shall be deemed to refer to any
Subsidiary through which LICENSEE shall so exercise such license rights.

2.11   LICENSEE shall have the further right to use the Licensed Technical
Information relating to Royalty Free Products in the development and
manufacture of any semiconductor laser chips and to exercise the license
rights specified in Section 2 as to any such semiconductor laser chips
without payment of any royalty pursuant to Section 4.2 hereof, subject to
the limitations and restrictions contained in this Agreement and the
payment of any patent royalties, as applicable.

2.12  For so long as IBM continues to manufacture the E2 Prototype Tool (the
"E2 Tool") for sale to any third party, IBM agrees to sell to LICENSEE E2
Tools on terms no less favorable than IBM has sold E2 Tools during the
preceding twelve (12) months to any other non-IBM customer purchasing
equivalent quantities of the E2 Tool as LICENSEE.  Such most favored terms
shall include price, production allocation, functionality of the E2 Tool
and payment terms and shall be granted to LICENSEE upon the condition that
LICENSEE accept all material terms upon which such most favored customer
purchased the E2 Tool.  In the event such most favored terms shall not
apply, IBM agrees to sell E2 Tools to LICENSEE on commercially reasonable
terms.

Upon written request by LICENSEE and in the event that IBM is no longer in
the business of supplying E2 Tools to third parties, IBM shall provide
LICENSEE with component part drawings and any other technical information,
including all improvements, necessary for the manufacture and operation of
E2 Tools, to the extent IBM can provide such information without violating
any obligations to third parties, at a reasonable cost invoiced to LICENSEE
to cover associated procurement expenses, and LICENSEE shall have the
nonexclusive right to manufacture E2 Tools for LICENSEE's internal use and
that of its Subsidiaries.  Any manufacture of the E2 Tool, or any portion
thereof, by LICENSEE may require additional patent licenses which the
parties agree to negotiate in good faith.

IBM shall make a good faith effort to notify LICENSEE of its intention to
stop manufacturing E2 Tools to third parties at least three (3) months
prior to the date it plans to stop such manufacture, and agrees to promptly
respond to all reasonable written requests from LICENSEE as to whether it
intends to stop such manufacture.

2.13     IBM disclaims any common law trademark rights that it may have
acquired through the use of the "E2" designation.  To the extent that IBM
has acquired any common law trademark rights in the "Laser Enterprise" or
"LE" designation, IBM hereby assigns all such rights to LICENSEE, together
with all goodwill pertaining thereto.

2.14  In the event that IBM now or hereafter obtains any patents which would
necessarily be infringed by the assembly by LICENSEE's customers of Royalty-
Free Products into an Erbium Doped Optical Fiber Amplifier ("EDFA")
configuration or EDFA architecture compliant package, IBM agrees to make a
license under such patents available to LICENSEE's customers in accordance
with IBM's licensing practices at such time.


Section 3.0 Confidentiality
          
3.1     For a period of ten (10) years from the Effective Date, LICENSEE
agrees to use the same degree of care and discretion, but at least a
reasonable level of care and discretion, to avoid any disclosure,
publication, or dissemination of any part or all of the Licensed
Information outside of LICENSEE, and its Subsidiaries, as LICENSEE employs
with information of its own which it regards as confidential and which it
does not desire to publish, disclose or disseminate.  If any Licensed
Information of a third party requires a different standard of care or
different period of confidentiality than that specified above, LICENSEE
agrees to protect such third party's Licensed Information in accordance
with the terms of the agreement under which such information was received
by IBM.

3.2     Disclosure of Licensed Information shall not be precluded, if such
disclosure is:

     (a)  in response to a valid order of a court or other governmental
          body; provided, however, that LICENSEE shall first have given
          notice to IBM and made a reasonable effort to obtain a protective
          order requiring that the information and/or documents so
          disclosed be used only for the purposes for which the order was
          issued;
          
     (b)  otherwise required by law;
          
     (c)  reasonably necessary to establish rights under this Agreement
          (but only to the extent necessary to do so); or
          
     (d)  reasonably necessary to exercise LICENSEE's license rights
          hereunder and such disclosure is made to an entity or other
          person that is bound as to the nondisclosure of such Licensed
          Information by a written agreement that is no less restrictive
          than this Section 3.
          
3.3     No obligation of confidentiality shall attach to:

     (a)  any information that LICENSEE already possesses without
          obligation of confidentiality;
          
     (b)  any information LICENSEE rightfully receives from another without
          obligation of confidentiality; or
          
     (c)  any information that is, or becomes, publicly available without
          breach of this Agreement.
          
3.4   In the event that LICENSEE discovers any IBM confidential information
in the possession of Employees that is unrelated to the Licensed Products,
it will promptly return such information to IBM.

3.5   IBM agrees not to disclose the trade secret information described in
(              Information redacted and filed separately.                ) 
for a period of three (3) years from the Effective Date subject to
Sections 3.2(a) & (b).  IBM agrees not to disclose the trade secret
information relating to the process (
                Information redacted and filed separately.
                              ) for a period of two (2) years from the
Effective Date subject to Sections 3.2(a) & (b).  Notwithstanding the
above, neither (i) the inherent disclosure of such information in IBM's
products, nor (ii) the disclosure of such information as part of a
disclosure of process information relating to products other than Royalty-
Free Products and Royalty-Bearing Products shall be deemed to be a
violation of this Section 3.5.


Section 4.0 Consideration
          
4.1   As partial consideration for the licenses granted by IBM to LICENSEE
in Sections 2.1, 2.2 and 2.3 with respect to R-F Products, LICENSEE shall
pay IBM the amount of twenty-seven million US dollars (US $27,000,000), on
the Effective Date, which sum is nonrefundable, in accordance with
instructions to be provided by IBM prior to such date.

4.2     As partial consideration for the licenses granted by IBM to LICENSEE
in Sections 2.1 and 2.2 with respect to R-B Products, LICENSEE shall pay
IBM a royalty of five percent (5%) of Selling Price.  LICENSEE acknowledges
that any royalties owing for patents covering R-B Products shall be payable
in addition to the royalty specified herein, pursuant to a separate patent
license agreement between the parties.

4.3     LICENSEE shall bear and pay all taxes (including, without limitation,
sales and value added taxes) imposed by any national, provincial or local
government of any country in which LICENSEE is doing business as a result
of the existence of this Agreement or the exercise of rights hereunder;
provided, that the foregoing shall not obligate LICENSEE to pay any tax
based on the income, gross receipts or property of IBM.

4.4     LICENSEE shall be liable for interest on any overdue payment or
royalty, commencing on the date such payment or royalty was due and ending
upon payment by LICENSEE, at an annual rate which is the greater of ten
percent (10%) or one percentage point higher than the prime interest rate
as quoted by the head office of Citibank N.A., New York, at the close of
banking on such date, or on the first business day thereafter if such date
falls on a non-business day.  If such interest rate exceeds the maximum
legal rate in the jurisdiction where a claim therefore is being asserted,
the interest rate shall be reduced to such maximum legal rate.

4.5     Royalties shall accrue when an R-B Licensed Product, with respect to
which royalty payments are required by this Agreement, is first sold or
otherwise transferred to a party other than LICENSEE or its Subsidiaries
(including, except as otherwise agreed in writing by IBM, sold or otherwise
transferred to IBM or any of its Subsidiaries).  To the extent an
R-B Licensed Product is incorporated as a component, subassembly or
subsystem in another product, the Selling Price shall be determined based
on the published list price (or if no such published list price exists, the
fair market value) of such R-B Licensed Product exclusive of any other
portion of such product.

4.6     LICENSEE shall pay all royalties and other payments due hereunder in
United States dollars.  All royalties for an accounting period computed in
other currencies shall be converted into United States dollars at the
exchange rate for bank transfers from such currency to United States
dollars as quoted by the head office of Citibank N.A., New York, at the
close of banking on the last day of such accounting period (or the first
business day thereafter if such last day shall be a non-business day).

4.7   LICENSEE's accounting period shall be semiannual and shall end on the
last day of each June and December during the term of this Agreement.
Within sixty (60) days after the end of each such period LICENSEE shall
furnish to IBM a written report containing the information specified in
Section 4.8 and shall pay to IBM all unpaid royalties accrued hereunder to
the end of each such period.  Such payments will be nonrefundable.

4.8  LICENSEE's written report shall be certified by an officer of LICENSEE
and shall contain the following information:

     (a)  for each type of R-B Licensed Product upon which royalty has
          accrued:  a description of said R-B Licensed Product, the
          quantity sold or otherwise transferred during the accounting
          period, and the sum of the Selling Price for such quantity; and
          
     (b)  the aggregate amount of all royalties due.
          
In the event no royalties are due, LICENSEE's report shall so state.

4.9     LICENSEE shall keep records in accordance with generally accepted
accounting principles and in sufficient detail to permit the determination
of which products are subject to royalty payments under this Agreement, the
royalties due IBM, and the accuracy of the information on LICENSEE's
written reports.  Such records shall include, but not be limited to,
detailed records supporting the information provided under Section 4.8.
Such records shall be kept for six (6) years following the due date for the
report relating to the reporting period to which such records pertain.

Upon IBM's written request for an audit, LICENSEE shall permit auditors
designated by IBM, together with such legal and technical support as IBM
deems necessary, to examine, during ordinary business hours, records,
materials, and manufacturing processes of LICENSEE for the purpose of
determining royalties due IBM.

Such audit shall be restricted to an audit of those records, materials, and
manufacturing processes related to R-B Licensed Products.  Such records and
materials shall be deemed to include general financial information to
provide a cross-check for the amount of royalties reported.

LICENSEE shall provide its full cooperation in such audit.  Such
cooperation shall include, but not be limited to, providing sufficient time
for such examination and convenient access to relevant personnel and
records.

Each party shall pay the charges that it incurs in the course of the audit.
However, in the event that the audit establishes underpayment greater than
or equal to the lesser of:  five percent (5%) of the royalties which should
have been paid for the accounting periods being audited or the cost of the
audit, then LICENSEE shall reimburse IBM for the costs IBM incurred in
conducting such audit.  However, such costs shall not include salaries paid
to IBM employees associated with such audit and such reimbursement shall
not exceed the amount of underpayment.

4.10   In the event an audit under the provisions of Section 4.9 identifies
an underpayment of royalties by LICENSEE, LICENSEE shall pay an amount
equal to the sum of such underpayment, any interest due under the
provisions of Section 4.4, and any reimbursement to IBM for the costs IBM
incurred in conducting such audit as specified by Section 4.9, within sixty
(60) days of IBM's written request.  Reimbursements due for costs shall
also be subject to interest under the provisions of Section 4.4.

4.11  IBM agrees that any statements or audit results furnished or otherwise
made available to or obtained by IBM pursuant to this Section 4.0 shall be
subject to equivalent confidentiality restrictions set forth in Section 3
and shall not be disclosed by IBM for a period of three (3) years from the
date of disclosure.


Section 5.0 Term; Termination and Assignability
          
5.1   The licenses granted in Sections 2.1 and 2.2 with respect to Licensed
Products shall remain in effect unless terminated in accordance with this
Section 5.0.  The patent license granted in Section 2.3 with respect to
R-F Licensed Products shall remain in effect for a period of five (5) years
from the Effective Date, unless terminated in accordance with this
Section 5 or extended pursuant to the option granted in Section 2.6.  The
patent license granted to IBM in Section 2.7 shall remain in effect for a
period of five (5) years from the Effective Date.

5.2    If LICENSEE is in material breach of its obligations hereunder with
respect to R-B Licensed Products and IBM provides written notice to
LICENSEE specifying the nature of such breach, LICENSEE shall either cure
such breach or produce a plan for such cure reasonably acceptable to IBM
within sixty (60) days after such written notice.  If LICENSEE does not
provide a plan for cure, or comply with a plan reasonably acceptable to
IBM, IBM shall have the right to terminate the licenses granted to LICENSEE
with respect to R-B Licensed Products under this Agreement by giving
written notice of termination to LICENSEE.  For purposes of this
Section 5.2, a material breach by LICENSEE shall mean and be limited to:
(i) an intentional and continuing breach of its obligations under Section 3
hereof or of the license restrictions in Section 2 hereof with respect to
Licensed Information relating to R-B Licensed Products; (ii) LICENSEE being
more than fifty thousand dollars ($50,000) in arrears on its payment
obligations herein that are not otherwise subject to a good faith dispute
between IBM and LICENSEE; or (iii) the failure by LICENSEE to submit
reports or permit audits as specified in Section 4.

5.3     If LICENSEE is in material breach of its obligations hereunder with
respect to R-F Licensed Products and IBM provides written notice to
LICENSEE specifying the nature of such breach, LICENSEE shall either cure
such breach or produce a plan for such cure reasonably acceptable to IBM
within sixty (60) days after such written notice.  If LICENSEE does not
provide a plan for cure, or comply with a plan reasonably acceptable to
IBM, IBM shall have the right to terminate the licenses granted to LICENSEE
with respect to R-F Licensed Products under this Agreement by giving
written notice of termination to LICENSEE.  For purposes of this
Section 5.3, a material breach by LICENSEE shall mean and be limited to an
intentional and continuing breach of its obligations under Section 3 hereof
or of the license restrictions in Section 2 hereof with respect to Licensed
Information relating to R-F Licensed Products.

5.4   In addition, in the event that LICENSEE engages in or suffers any of
the following events of default:

     (a)  becomes insolvent, is dissolved or liquidated, files or has filed
          against it a petition in bankruptcy, reorganization, dissolution
          or liquidation or similar action filed by or against it, is
          adjudicated as bankrupt, or has a receiver appointed for its
          business; or
          
     (b)  has all or a substantial portion of its capital stock or assets
          expropriated or attached by any government entity;
          
then LICENSEE shall promptly notify IBM in writing that such event has
occurred.  If any default as specified above in this Section 5.3 is not
cured, or an acceptable plan for such cure is not proposed within ninety
(90) days after written notice from IBM specifying the nature of the
default, IBM shall have the right to terminate this Agreement by giving
written notice of termination to LICENSEE.

5.5   This Agreement and any rights or licenses granted herein are personal
to the parties and neither shall assign or sublicense any of its rights or
privileges hereunder.  Any attempted act in derogation of the foregoing
shall be considered void.  Notwithstanding the foregoing, in the event of a
transfer by LICENSEE of all or substantially all of its assets or those of
the Laser Operations, LICENSEE shall have the right to assign this
Agreement to the purchaser of such assets, provided:  (i) such purchaser
agrees in writing to be bound by all terms and conditions hereof, (ii) in
the event that such purchaser and IBM are involved in any intellectual
property dispute at the time of such transfer, such purchaser shall resolve
such dispute to IBM's satisfaction; both as conditions precedents to the
effectiveness of such assignment.

5.6     No failure or delay on the part of IBM in exercising its right of
termination hereunder for any one or more causes shall be construed to
prejudice its right of termination for such causes or any other or
subsequent causes.

5.7  Upon termination of this Agreement, all licenses granted in Section 2
will automatically terminate, and LICENSEE shall promptly return to IBM or
destroy all tangible information containing Licensed Information.  The
confidentiality obligations of Section 3 will remain in effect beyond any
termination for the time period stated in Section 3.1.

     PATENT LICENSE AGREEMENT ("Agreement") with an Effective
Date of March 10, 1997 between INTERNATIONAL BUSINESS MACHINES CORPORATION,
a New York corporation ("IBM"), and UNIPHASE CORPORATION, a Delaware
corporation ("LICENSEE").

     Contemporaneously with the execution of this Agreement, the parties
have entered into a Technology License Agreement which includes, in part, a
license under certain technology owned by IBM to manufacture and sell
Royalty-Bearing Products (as defined in such Technology License Agreement).
The exercise of such technology license by LICENSEE may require a license
under the IBM patents listed in Exhibit 1 (the "Licensed Patents").
LICENSEE desires to acquire a nonexclusive license under the Licensed
Patents for such Royalty-Bearing Products.

In consideration of the premises and mutual covenants herein contained, IBM
and LICENSEE agree as follows:

Section 1.  Definitions
1.1  "Patented Portion" shall mean that portion of a Product which:
(a)embodies or uses all the elements or steps recited in any one Claim of
     one Licensed Patent; or
(b)is manufactured by use of all the steps recited in any one Claim of one
     Licensed Patent.

1.2  "Products" shall mean semiconductor laser chips other than Royalty-
Free Products (as defined in the Technology License Agreement).

1.3  "Selling Price" shall mean the actual selling price to unaffiliated
customers, and the greater of actual selling price or fair market value in
sales to affiliated customers; provided that in either case the Selling
Price shall be reduced for discounts, taxes, transportation fees and other
unreimbursed charges paid by LICENSEE or its Subsidiaries in connection
with the sale of Products.

1.4  "Subsidiary" shall mean a corporation, company or other entity:
(a)more than fifty percent (50%) of whose outstanding shares or securities
     (representing the  right to vote for the election of directors or
     other managing authority) are, now or hereafter, owned or controlled,
     directly or indirectly, by a party hereto, or
(b)which does not have outstanding shares or securities, as may be the case
     in a partnership, joint venture or unincorporated association, but
     more than fifty percent (50%) of whose ownership interest representing
     the right to make the decisions for such corporation, company or other
     entity is now or hereafter, owned or controlled, directly or
     indirectly, by a party hereto, but such corporation, company or other
     entity shall be deemed to be a Subsidiary only so long as such
     ownership or control exists.

1.5  "Claim" shall mean an allowed claim under a Licensed Patent that has
not expired or been adjudicated invalid.

Section 2.     License
2.1  IBM grants to LICENSEE and its Subsidiaries a nonexclusive license
under the Licensed Patents to make, use, import, offer to sell, sell and
otherwise transfer Products.  The license as to any Subsidiary shall
terminate on the date such Subsidiary ceases to be a Subsidiary.
Additionally, subject to Section 2.4, IBM grants to LICENSEE and its
Subsidiaries a nonexclusive license under the Licensed Patents the right to
have LICENSEE's Products made by another manufacturer for the use and/or
lease, sale or other transfer only by LICENSEE and its Subsidiaries.  Such
license shall further include the right to incorporate Products as
components, subassemblies or subsystems in other products manufactured
and/or sold by LICENSEE and its Subsidiaries.

2.2  No license is granted pursuant to Section 2.1 with respect to any
particular Product, unless:
(a)a Licensed Patent defines a Patented Portion of said Product;
(b)said Licensed Patent is identified in a report as covering said Product,
     if required by Section 4.5; and
(c)either the royalty attributable to said Product is paid as required by
     Section 4.2, or a late payment of said royalty is made and accepted by
     IBM pursuant to Section 4.4.

2.3  No license, immunity or other right is granted under this Agreement,
either directly or by implication, estoppel, or otherwise:
(a)other than under the Licensed Patents;
(b)with respect to any item other than a Product notwithstanding that such
     other item may incorporate one or more Products; or
(c)to parties acquiring any item from LICENSEE or its Subsidiaries for the
     combination of such acquired item with any other item, including other
     items provided by LICENSEE or its Subsidiaries, or for the use of any
     such combination even if such acquired item has no substantial use
     other than as part of such combination.

2.4  The license to have Products made granted in Section 2.1 to LICENSEE:
(a)  shall only apply when the specifications for LICENSEE's Products were
     created by LICENSEE (either solely or jointly with one or more third
     parties);
(b)  shall only be under Claims of Licensed Patents, the infringement of
     which would be necessitated by compliance with such specifications;
(c)  shall not be under Claims for a method or process unless such method
     or process is based upon technology created by LICENSEE (either solely
     or jointly with one or more third parties) or otherwise licensed by
     IBM to LICENSEE; and
(d)  shall not apply to any Products in the form manufactured or marketed
     by said other manufacturer prior to LICENSEE furnishing said
     specifications.

     Unless LICENSEE informs IBM to the contrary, LICENSEE shall be deemed
to have authorized said other manufacturer to make LICENSEE's Products
under the license granted to LICENSEE in Section 2.1 when the condition
specified in Section 2.4(a) is fulfilled.  In response to a written request
identifying a Product and a manufacturer, LICENSEE shall in a timely manner
inform IBM of the quantity of such Product, if any, manufactured by such
manufacturer pursuant to the license granted in Section 2.1.

2.5  LICENSEE shall have the right to exercise any license rights granted
hereunder through any Subsidiary, and any reference in this Section 2 to
LICENSEE shall be deemed to refer to any Subsidiary through which LICENSEE
shall so exercise such license rights.

Section 3.   Payment
3.1  LICENSEE, on behalf of itself and its Subsidiaries, shall pay a
royalty for each Product which contains a Patented Portion at a rate
computed at the following percentages of Selling Price of such Product:

      Number of Licensed Patents     Percentage of
      Covering the Product           Selling Price

                1                         1%
                2                         2%
                3                         3%
                4                         4%
                5 or more                 5%

For the purposes of this Section 3.1, a Licensed Patent and its
corresponding patents in other countries, listed in Exhibit 1, shall be
deemed to be one Licensed Patent.

Royalties shall only be payable on one occasion for each Product
manufactured and sold by LICENSEE or its Subsidiaries.  To the extent a
Product consisting of a semiconductor laser chip, which is subject to
LICENSEE's royalty obligations pursuant to this Section 3.1, is
incorporated as a component, subassembly or subsystem in another product,
the Selling Price shall be determined based on the published list price (or
if no such published list price exists, the fair market value) of such
semiconductor laser chip exclusive of any other portion of the product that
does not contain Patented Portions.

3.2  Subject to Section 3.4, no royalties shall be paid by LICENSEE with
respect to Products which LICENSEE purchases from a third party licensed
under all of the Licensed Patents to sell such Products, and for which
Products a royalty or other consideration was paid to IBM.

3.3  If LICENSEE purchases from a third party portions of a Product and
combines such portions with each other and/or with other portions such that
the combination is itself a Product which includes a Patented Portion not
fully included in any individual purchased portion, then royalty shall be
due for the combination in accordance with this Section 3, whether or not
said third party is authorized by IBM to sell said purchased portions.

3.4  Any semiconductor laser chip that would otherwise be subject to
LICENSEE's royalty obligations pursuant to this Section 3 shall not be
subject to such royalty obligations if such chip is sold by LICENSEE (or
any Subsidiary of LICENSEE authorized to exercise LICENSEE's license rights
hereunder pursuant to Section 2.5 hereof) to a customer that is licensed by
IBM at the time of such sale as to the Patented Portion that would
otherwise give rise to such royalty obligation; provided such customer
notifies LICENSEE, in writing at or prior to the time of such sale, that it
is exercising its own "have made" rights as to such Patented Portion, and
LICENSEE notifies IBM, of its intention to excercise such exclusion from
its royalty obligation in the royalty report for such reporting period.

Section 4.     Accruals, Records, Reports and Other Information
4.1  Royalties shall accrue when a Product, with respect to which royalty
payments are required by this Agreement, is first sold or otherwise
transferred (including, sold or otherwise transferred to IBM or any of its
Subsidiaries), or first used in each country of use, by or for LICENSEE or
any of its Subsidiaries.

4.2  LICENSEE's accounting period shall be semiannual and end on the last
day of each June and December during the term of this Agreement.  Within
sixty (60) days after the end of each such period, LICENSEE shall furnish
to IBM a written report containing the information specified in Section 4.5
and shall pay to IBM all unpaid royalties accrued hereunder through the end
of each such period.

4.3  LICENSEE shall pay all royalties and other payments due hereunder in
US dollars.  All royalties for an accounting period computed in other
currencies shall be converted into US dollars at the exchange rate for bank
transfers from such currency to US dollars as quoted by the head office of
Citibank N.A., New York, USA, at the close of banking on the last day of
such accounting period (or the first business day thereafter if such last
day is a non-business day).

4.4  IBM may accept a late payment provided such payment includes all
overdue royalties or other payment plus interest. The interest on any
overdue royalty or other payment shall be calculated commencing on the date
such royalty or other payment became due, using an annual rate which is the
greater of ten percent (10%) or one percentage point higher than the prime
interest rate as quoted by the head office of Citibank N.A., New York, USA
at the close of banking on such date, or on the first business day
thereafter if such date falls on a non-business day.  If such interest rate
exceeds the maximum legal rate in the jurisdiction where a claim therefor
is being asserted, the interest rate shall be reduced to such maximum legal
rate.

4.5  LICENSEE's written report shall be certified by an officer of LICENSEE
and shall contain the following information:
(a)a description of each type of Product, the quantity sold or otherwise
     transferred during the accounting period, and the sum of the Selling
     Prices for such quantity;
(b)identification of each Licensed Patent covering each such Product.
     However, if LICENSEE pays royalties for the use of five (5) or more
     Licensed Patents, LICENSEE shall have no obligation to identify the
     Licensed Patents for that Product;
(c)the amount of royalties due for each type of Product; and
(d)the aggregate amount of all royalties due.
In the event that any of Sections 4.5(a) through 4.5(d) does not apply to
an accounting period, LICENSEE shall so indicate.  In the event no
royalties are due, LICENSEE's report shall so state.

4.6  For the purpose of determining obligations under IBM patents, LICENSEE
shall, within thirty (30) days of a written request by IBM:
(a)provide to or make available for inspection by IBM or its designee any
     Product or a copy of any materials relevant to any Product identified
     by IBM;
(b)sell, license or otherwise transfer and deliver to IBM any Product at
     any time offered for sale or transferred by LICENSEE; and
(c)provide to IBM or its designee access to those manufacturing processes
     used by LICENSEE in the manufacture of Products.

4.7  LICENSEE shall keep records in accordance with generally accepted
accounting principles and in sufficient detail to permit the determination
of royalties due to IBM. Such records shall include, but not be limited to,
detailed records supporting the information provided under Section 4.5.
Such records shall be kept for six (6) years following the submission of
the related report.

Upon written notice for an audit, LICENSEE shall permit auditors designated
by IBM, together with such legal and technical support as IBM deems
necessary, to examine, during ordinary business hours, records, materials,
and manufacturing processes of LICENSEE for the purpose of verifying
compliance with this Agreement.

Each party shall pay the costs that it incurs in the course of the audit.
However, in the event that the audit establishes underpayment greater than
five percent (5%) of the royalties due, LICENSEE shall reimburse IBM for
the cost of the audit; provided, however, such reimbursement shall not
exceed the amount of the underpayment.

4.8  IBM agrees that any statements or audit results furnished or otherwise
made available to or obtained by IBM pursuant to this Section 4.0 shall be
subject to equivalent confidentiality restrictions set forth in Section 3
of the Technology License Agreement and shall not be disclosed by IBM for a
period of three (3) years from the date of disclosure.

Section 5.   Term; Termination
5.1  The license granted herein shall remain in effect for a period of five
(5) years from the Effective Date, unless earlier terminated under the
provisions of this Agreement.

5.2  LICENSEE may terminate the license granted herein, in whole or as to
any specified Licensed Patent by giving notice in writing to IBM; provided,
however, that termination of the license as to any specified Licensed
Patent shall include termination of the license as to all corresponding
Licensed Patents in other countries. Any such termination shall be
irrevocable.

5.3  IBM shall have the right to terminate this Agreement, or the license
granted hereunder, if LICENSEE is more than fifty-thousand dollars
($50,000) in arrears in its payment obligations or if LICENSEE fails, at
any time to:
(a)maintain records which substantially meets the requirements of Section
     4.7;
(b)make a report which substantially meets the requirements of Section 4.5;
     or
(c)permit an audit pursuant to Section 4.7; and

if LICENSEE does not cure such breach within sixty (60) days after mailing
of written notice from IBM to LICENSEE specifying the nature of such
breach; unless such breach is the subject of a good faith dispute between
IBM and LICENSEE. IBM's termination of this Agreement or of the license
shall be effective upon written notice.

5.4  No termination of this Agreement or the license granted hereunder
shall relieve LICENSEE of any obligation or liability accrued hereunder
prior to such termination.

Section 6.     Option Granted
6.1  LICENSEE grants to IBM, the right to obtain a license to make, use,
import, offer to sell, sell and otherwise transfer any information handling
system product.  Said license shall be on terms, including royalty rates,
no less favorable than those granted to LICENSEE herein or in any amendment
hereto.  Said right shall bewith respect to any patent under which LICENSEE
or any of its Subsidiaries has the right to grant licenses to unaffiliated
third parties at any time on or before the Effective Date and shall be
limited to a number equivalent to the number of Licensed Patents licensed
hereunder.

The Agreement for Exchange of Confidential Information
________________________________________________________________________
___


Uniphase Corporation          International Business Machines Corporation
163 Baypointe Parkway         c/o Research Division
San Jose, CA 95134            Zurich Research Laboratory
                              CH-8803 Ruschlikon
Uniphase Laser Enterprise AG
c/o Treuhand von Flue AG,
Grienbackstrasse 17
CH-6301 Zug


Uniphase Corporation and Uniphase Laser Enterprise AG collectively
(Uniphase) and International Business Machines Corporation (IBM) agree
that the following terms and conditions apply when one of the parties
(Discloser) discloses Confidential Information (Information) to the
other (Recipient) under this Agreement.

Uniphase and IBM agree that our mutual objective under this Agreement is
to provide appropriate protection for Information while maintaining our
ability to conduct our respective business activities.

Information means any and all information disclosed to, or obtained
through observation on other perception at the jointly occupied facility
located at Ruschlikon, Saumerstrasse 4, by either party pertaining to
the other party (Disclosing Party) which is marked with a restrictive
legend, or which, in the reasonable judgement of an ordinary person,
would appear to be of a proprietary nature and, therefore, in his
judgement, should not be disclosed to a third party without the
Discloser's consent; including business, financial, customer, supplier,
and technical data.

1.DISCLOSURE

The Discloser's and the Recipient's Point of Contact will coordinate and
document as necessary the disclosure. The initial Point of Contact for 
Uniphase will be Volkar Graf and for IBM will be Peter Buttner. Either 
party may change its Point of Contact by notifying the other party in 
writing. Information will be disclosed either:

a) in writing;
b) by delivery of items;
c) by initiation of access to Information, such as may be contained in a
   data base; or
d) by oral and/or visual presentation;
e) by accidental observation.



Information should be marked with a restrictive legend of the Discloser.
If Information is not marked with such legend or is disclosed orally or
observed accidentally, 1) the Information will be identified as confidential 
at the time of disclosure or within ten (10) working days and 2) the 
Discloser will promptly provide the Recipient's Point of Contact with a 
written summary including the date disclosed and a brief
non-confidential description of the Information.

2.OBLIGATIONS

The Recipient agrees to use the same care and discretion to avoid
disclosure,
publication or dissemination of the Discloser's Information as it uses
with its own
similar Information that it does not wish to disclose, publish or
disseminate. The
Recipient may use the Discloser's Information for any purpose which does
not violate
such obligation, but will not disclose Information to third parties
without the
permission of the Discloser.


3.CONFIDENTIALITY PERIOD / TERM

Information disclosed pursuant to this Agreement will be subject to the
terms of this Agreement for three years from the date of disclosure. The Term 
of this Agreement will begin on March 10, 1997 and will expire upon the 
termination or expiration date of the Laboratory Real Estate Lease Agreement 
entered into by Uniphase and IBM (the "Lease Agreement") or June 30, 1999 
which ever is earlier.

4.EXCEPTIONS TO OBLIGATIONS

The Recipient may disclose, publish, disseminate, and use Information
that is
1) already in its possession without obligation of confidentiality;
2) developed independently;
3) obtained from a source other than the Discloser without obligation of
    confidentiality;
4) publicly available when received, or thereafter becomes publicly
available through
    no fault of the Recipient; or
5) disclosed by the Discloser to another party without obligation of
confidentiality.

5.RESIDUAL INFORMATION

The Recipient may disclose, publish, disseminate, and use the ideas,
concepts,
know-how and techniques, related to the Recipient's business activities,
which are
contained in the Discloser's Information and retained in the memories of
Recipient's
employees who have had access to the Information pursuant to this
Agreement
(Residual Information).

Nothing contained in this Section gives the Recipient the right to
disclose, publish, or
disseminate, except as set forth elsewhere in this Agreement:
1) the source of Residual Information;
2) any financial, statistical or personnel data of the Discloser; or
3) the business plans of the Discloser.

6.DISCLAIMERS

THE DISCLOSER PROVIDES INFORMATION SOLELY ON AN "AS IS" BASIS.

The Discloser will not be liable for any damages arising out of the use
of Information
disclosed hereunder.

Neither this Agreement nor any disclosure of Information hereunder
grants the
Recipient any right or license under any trademark, copyright or patent
now or
hereafter owned or controlled by the Discloser.

The receipt of Information pursuant to this Agreement will not preclude,
or in any way
limit, the Recipient from:
1) providing to others products or services which may be competitive
with products or
    services of the Discloser;
2) providing products or services to others who compete with the
Discloser; or
3) assigning its employees in any way it may choose.


7.GENERAL

This Agreement does not require either party to disclose or to receive
Information.

Neither party may assign, or otherwise transfer, its rights or delegate
its duties or obligations under this Agreement without prior written consent. 
Any attempt to do so is void.

This Agreement may only be modified by a written agreement signed by
authorized representatives of both parties.

Neither party may terminate this Agreement unless the Lease Agreement
expires or is terminated. Any provisions of this Agreement which by their 
nature extend beyond its termination remain in effect until fulfilled and 
apply to both parties' successors and assigns.

Waiver of any breach of this Agreement shall not be a waiver of any
subsequent breach nor shall it be a waiver of the underlying obligations.

The Laws of State of New York, without regard to its principles of conflicts
of lows govern this Agreement.





The parties acknowledge that they have read this Agreement, understand
it, and agree to be bound by its terms and conditions. This Agreement is
the complete and exclusive agreement between the parties regarding
disclosures of Information and replaces any prior oral or written
communications between the parties. Once signed, any reproduction of
this Agreement made by reliable means (for example, photocopy or
facsimile) is considered an original.
