                      INFORMATION TO BE INCLUDED IN REPORT

ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.

        On June 9, 1998, pursuant to that certain Master Purchase Agreement
dated as of May 29, 1998 (the "Master Agreement"), among Koninklijke Philips
Electronics N.V., a Netherlands corporation ("Philips"), Uniphase Corporation, a
Delaware corporation (the "Registrant"), and certain indirect wholly-owned
subsidiaries of the Registrant, Registrant acquired, through such wholly-owned
subsidiaries, Philips Optoelectronics B.V., a Netherlands corporation ("OPTO").
OPTO is in the business of, among other things, designing, developing,
manufacturing, marketing and selling optoelectronic components, modules and
subsystems in the global telecommunications, cable television, multimedia and
printing industries. The acquisition was completed in two steps: (a) the sale to
the Registrant of OPTO's foreign and U.S. intangible assets; followed by (b) the
sale to the Registrant of all of OPTO's outstanding capital stock.

        The assets acquired by the Registrant pursuant to the transaction
include all assets of OPTO, which consist of, among other things, OPTO's
accounts receivable, inventory, fixed and tangible personal property (including,
without limitation, all machinery, equipment, supplies, tools, furniture,
fixtures, hardware, and spare parts), intangible personal property, contracts,
and books and records. The assets acquired also include certain intellectual
property used in OPTO's business.

        In addition to the personal property assets acquired in the transaction,
the Registrant also acquired, through OPTO, a leasehold interest in and to
certain real property in Eindhoven, The Netherlands, at which OPTO currently
conducts its business. Philips has agreed that, during the term of the lease, it
will provide OPTO with certain services necessary to the conduct of OPTO's
business.

        It is currently anticipated that all of the assets acquired by the
Registrant will continue to be used by the Registrant in conducting the business
of OPTO as conducted when the same was acquired by the Registrant.

        The consideration paid by the Registrant to Philips in connection with
such acquisition consisted of (1) 3.6 million newly issued restricted shares of
the Registrant's common stock, and (2) 100,000 shares of newly issued restricted
shares of the Registrant's Series A Preferred Stock, which shares of Series A
Preferred Stock are convertible into shares of the Registrant's common stock
based on, among other things, the achievement of certain product shipment
milestones by OPTO during the four year period commencing April 1, 1998 and
ending March 31, 2002. The consideration paid at the closing of the acquisition
was determined through arms-length negotiations between the Company and Philips,
which negotiations took into account OPTO's business, financial position,
operating history, products, intellectual property and other factors relating to
OPTO's business. The shares of the Registrant's common stock issued to Philips
at the closing of the acquisition and the shares into which the shares of Series
A Preferred Stock issued to Philips at the Closing are convertible are subject
to certain registration rights.

            ordinary course of business to a purchaser in accordance with OPTO's
            ordinary course pricing practices (allowing for negotiations). All
            such materials, work in process and finished goods that comprise the

            infringement of any Intellectual Property of any other Person, and
            no facts, events or circumstances have occurred which may give rise

            or conduct the business of OPTO as presently conducted, or as

            5.10(a), or otherwise required to be transferred pursuant to the
            Sale Agreements, does not constitute all of the Intellectual
            Property necessary to enable OPTO to conduct the Activity in the

            to be conducted by Philips.

            Activity or the assets of OPTO. OPTO is not engaged in or a party to

            proceedings), none is pending or threatened in writing and to
            Philips' Knowledge no facts are known which make such litigation or
            dispute to be expected.

      (ii)  Without limiting Section 5.11(i) above, no Claim has been made by
            any Person as a result of any defect or deficiency or claimed defect
            or deficiency in any product manufactured, assembled or sold by

            retirement or severance payment or benefit granted or the cost of

      (v)   Apart from Messrs. Griede, Irijanan, Brans and Van de Heuvel, OPTO
            does not employ or have the benefit of any secondment arrangement in
            relation to an employee of another Philips' Affiliate under which
            either the employee has a right to return to the other Philips'
            Affiliate or the employee has expatriate salary or other benefits.

      (vi)  Apart from the Philips Collective Labour Agreement, a copy of which
            has previously been provided to Uniphase, OPTO is not a party to or
            subject to any collective bargaining agreements with any trade union
            or collective bargaining agent representing any of the OPTO
            Employees or any other Persons.

      (vii) To Philips' Knowledge, no OPTO Employee is in violation of any term
            of any employment contract, proprietary information agreement or any
            other agreement relating to the right of any such individual to be
            employed by, or to contract with, OPTO, and to Philips' Knowledge
            the continued employment by OPTO of the OPTO Employees, will not
            result in any such violation. Philips has not received any notice
            alleging that any such violation has occurred. Philips has no
            Knowledge that any manager, director or key employee, or that any
            group of key employees, intends to terminate his, her or their
            employment with OPTO, nor, except as otherwise specifically provided
            herein, does OPTO have a present intention to terminate the
            employment of any officer, key employee or group of key employees.

              following their retirement. No Employee Benefit Plan exists that
              could result in the payment to any employee of any money, benefits
              or other property or accelerate or increase the funding
              requirements for any Employee Benefit Plan, in each case as a
              result of the transactions contemplated hereby.

      (xv)    There are no employment policies or plans, including policies or
              plans regarding incentive compensation, stock options, severance
              pay or other terms or conditions of employment or terms or
              conditions upon which Employees may be terminated, which are
              binding upon OPTO.

      (xvi)   OPTO has been and is being operated in full compliance with all
              legal requirements relating to employees, including employment
              standards, occupational health and safety, pay equity and
              employment equity. There have been no complaints under such laws
              against Philips or OPTO.

      (xvii)  There are no complaints nor are there any threatened complaints,
              against OPTO or Philips, before any employment standards branch or
              tribunal or human rights tribunal. To Philips' Knowledge, nothing
              has occurred which might lead to a complaint against Philips or
              OPTO, under any human rights legislation or employment standards
              legislation. There are no outstanding decisions or settlements or
              pending settlements under the employment standards legislation
              which place any obligation upon OPTO, to do or refrain from doing
              any act.

      (xviii) There is no strike or lock out occurring or threatened affecting
              OPTO or the Activity.

                                                                              31


      (xix) OPTO has no unresolved employee grievances or pending arbitration
            cases outstanding. OPTO has no serious labour problems that might
            materially affect the value of OPTO or lead to an interruption of
            its operations at any location.

      (xx)  Except as set forth on Schedule 5.12(a), OPTO employs no independent
            contractors or consultants, and there are no Persons (other than the
            OPTO Employees) necessary to conduct the Activity, as the same is
            presently conducted and anticipated to be conducted in the future.

5.13. Permits.

      (i)   To Philips' Knowledge, all permits, permissions, easements,
            wayleaves, concessions, authorizations, licenses, consents and
            exemptions (collectively "Permits") required to operate OPTO and the
            Activity as presently conducted, all of which are listed on Schedule
            5.13 attached hereto, have been obtained and are in full force and
            effect and the operation of the Activity does not contravene and has
            not contravened the conditions of any Permits, and to the Knowledge
            of the Philips Parties none of the Permits held directly by OPTO
            will be withdrawn, revoked or cease to apply as a result of the
            transactions contemplated by this Agreement, save as set out in
            Schedule 5.13.

      (ii)  Philips has no Knowledge why the Uniphase Parties should not be able
            to obtain or renew any of the Permits referred to in clause (i)
            above upon proper submission by the applicable Uniphase Parties of
            applications therefor to the appropriate governmental or other body;
            however, Philips does not warrant such grant by the applicable
            governmental body. Philips has no Knowledge of any circumstances
            relating to the Uniphase Parties' proposed ownership or use of the
            Activity in the same manner as currently used by OPTO which would
            require the Buyers to obtain any Permit in addition to those
            referred to in Schedule 5.13.

5.14. Environmental Conditions

      (i)   To Philips' Knowledge, Philips and OPTO have at all times conducted
            the Activity in compliance with, and have not committed any act or
            failed to act 




<PAGE>   37

                                                                              32


            in any way which gave or will give rise to any liability or
            obligation under, Environmental Laws, including permits,
            concessions, regulations and zoning plans.

      (ii)  There is no lawsuit, proceeding or investigation, nor has there been
            issued any order or measure from any competent authorities relating
            to Environmental Laws or liabilities in respect thereof commenced
            or, to Philips' Knowledge, pending against Philips or OPTO in
            relation to the Activity or threatened against or affecting same.

      (iii) To Philips' Knowledge, at the locations where OPTO or Philips
            conducts or has conducted the Activity or will conduct the Activity:

            (a)   there is and will be at the OPTO Closing Date no contamination
                  of the soil (including the subsoil and groundwater);

            (b)   nor is there nor have there ever been any air emissions, noise
                  levels or water discharges in excess of permit limits or
                  except as otherwise allowed by applicable law or regulation;

            (c)   nor is there or has there ever been any storage, processing or
                  disposal of any waste or waste water in contravention or in
                  excess of permit limits or except as otherwise allowed by
                  applicable law or regulation; and

            (d)   nor is there or has there ever been any storage, processing or
                  disposal of substances, including dangerous substances,
                  chemicals, such as arsenics, in contravention or in excess of
                  permit limits or limits based on Environmental Laws, nor has
                  Philips ever infringed any obligation based on Environmental
                  Laws with respect to the storage, processing or disposal of
                  substances. The present use of arsenics at the Activity does
                  not require an external safety report.

      (iv)  To Philips' Knowledge, OPTO has no liability, contingent or actual,
            with regard to the condition of or presence of any waste or other
            contaminant in, under or on any property which is not currently
            occupied by it nor with regard 




<PAGE>   38

                                                                              33


            to any waste or other by-product disposed of by it. 

5.15. Brokers' Fees.

      None of OPTO, Philips or any of Philips' Affiliates has, nor will OPTO or
      any Uniphase Party acquire as a result of any act by any Philips'
      Affiliate, any liability to pay any fees or commissions to any broker,
      finder or agent with respect to the transactions contemplated by this
      Agreement or the other Sale Agreements.

5.16. Insurance.

      OPTO has insurance coverage which, given the size and nature of its
      business, is consistent with Philips' policy regarding such matters. All
      policies of insurance providing coverage to OPTO are in full force and
      effect but such coverage shall be terminated at the OPTO Closing Date.

5.17. [Intentionally Omitted]

5.18. Compliance with Laws.

      To Philips' Knowledge, each of Philips and OPTO has conducted the Activity
      in all material respects in accordance with all applicable laws,
      regulations and other requirements of each governmental body having
      authority over same, including without limitation all applicable
      competition and anti-trust laws and rules, and has not acted nor failed to
      act in any way which has given or will give rise to any violation of or
      liability under any of such laws, regulations or requirements. There are
      no contracts or obligations, agreements, arrangements or concerted
      practices to which OPTO is a party, and there are no practices in which
      OPTO is engaged, which are void, illegal, unenforceable, registrable or
      notifiable under or which contravene any anti-trust or similar legislation
      anywhere in the world.

5.19. Material Contracts.

      (i)   Schedule 5.19 attached hereto lists all Material Contracts. For the
            purpose hereof, the term "Material Contracts" means all of the
            following: (i) all outstanding licenses or other agreements between
            OPTO and its customers (including, without limitation, all such
            licenses and agreements relating to the

            sale or license of OPTO's products), (ii) all other licenses or
            other agreements pursuant to which OPTO licenses or has otherwise
            agreed to transfer, license or assign any right, title or interest
            in or to Intellectual Property owned or used by OPTO or the
            Activity, (iii) all other licenses or other agreements pursuant to
            which OPTO licenses or otherwise receives from another Person or
            entity any Intellectual Property of such other Person or entity,
            (iv) all employment or consultant contracts between OPTO and its
            employees and consultants, (v) all collective bargaining agreements
            and other labor agreements affecting OPTO or any of the OPTO
            Employees, (vi) all other agreements or understandings between OPTO
            and Philips or any of Philips' Affiliates, all of which, at
            Uniphase's election shall be terminated, with no further liability
            to OPTO, prior to the OPTO Closing Date, (vii) all instruments and
            other agreements evidencing, securing or otherwise relating to any
            debt of OPTO, if any, (viii) all real property leases pursuant to
            which OPTO is a party, (ix) all insurance policies held by OPTO, and
            (x) all other contracts, agreements, instruments, documents, and
            understandings which (1) involve future payments, performance of
            services or delivery of goods or materials to or by OPTO of an
            aggregate amount or value in excess of NLG 100,000, or (2) are
            material to OPTO or the Activity. Philips has previously delivered
            to Uniphase copies of all of the Material Contracts.

      (ii)  To Philips' Knowledge, each Material Contract is valid and in full
            force and effect, and is enforceable by OPTO in accordance with its
            terms.

      (iii) OPTO is not in material default under any Material Contract and, to
            Philips' Knowledge, no other Person or entity has defaulted under
            any Material Contract.

5.20. Grants.

      No act or transaction has been effected by Philips, OPTO or any of
      Philips' Affiliates including the sale of the OPTO Shares in consequence
      of which:

      (i)   OPTO is or could (under the terms of the grant or equivalent) be
            liable to:

                                                                              35

            (b)   repay in whole or in part any central or local governmental
                  authority loan;

                  by any authority; or


      (ii)  to the Knowledge of Philips, any grant for which application has
            been made on behalf of OPTO will or may not be paid or will or may
            be reduced pursuant to the present practice of the appropriate
            authority;

      Schedule 5.20 attached hereto.

      (i)   there has been no interruption or alteration in the nature, scope or
            manner in the Activity, and the Activity has been carried on in the
            ordinary and usual course of business so as to maintain the same as
            a going concern;

      (ii)  no material customer or supplier has:

            (a)   indicated that it is likely to cease trading with or supply to

                  with or supplies to OPTO; 

            (c)   indicated that it is likely to change materially the terms
                  upon which it is prepared to trade with or supply OPTO (other
                  than normal price and incidental changes);

                                                                              36


      (iii) OPTO has continued to pay its creditors in the ordinary course of
            business;

      (iv)  save for financing extended by Philips or its Affiliates to OPTO,

            or liable to be called upon to repay prematurely any loan capital or
            borrowed monies;

      (v)   OPTO has not, except in the ordinary course of business, acquired,
            sold, transferred or otherwise disposed of any assets of whatsoever
            nature, other than as set forth on Schedule 3.3;

      (vi)  OPTO has not cancelled, waived, released or discontinued any rights,
            debts or claims other than in the ordinary course of business;

      (vii) save as set forth in the purchase orders listed on Schedule 5.19 and

                                                                              37


5.22. Material Adverse Change.

      To Philips' Knowledge, since the date of incorporation of OPTO, there has
      not been any material adverse effect on the business, operations, finances
      or prospects of OPTO or the Activity.

5.23. Accounts Receivable and Accounts Payable.

      (i)   All accounts receivable of OPTO represent valid and binding
            obligations of OPTO's customers entered into in the ordinary course
            of business. All such accounts receivable will be collected in full
            (without any counterclaim or setoff) in the ordinary course of
            business, subject solely to the reserve for doubtful accounts as set
            forth in the Closing Date Balance Sheet. Notwithstanding anything to
            the contrary set forth in this Agreement, the aggregate liability of
            Philips due to the failure of all or any portion of such accounts
            receivable to be so collected and the failure of Philips
            representations regarding inventory at Section 5.6(ii) hereof shall
            be reduced by the aggregate amount of all payments received by OPTO
            from the applicable customers in reduction of such doubtful accounts
            (net of all costs and expenses incurred by OPTO to collect the
            same).

      (ii)  All accounts payable of OPTO were incurred in the ordinary course of
            business and represent arms-length obligations of OPTO.

6.2 Consents and Notifications.

      (i)   Promptly after execution hereof, Philips and OPTO will file (and
            Philips will cause OPTO to file) any notification and report forms
            and related material that Philips and/or OPTO may be required to
            file with any governmental authority (including, without limitation,
            all filings and notifications under the HSR Act), will use its best
            efforts to obtain (and Philips will cause OPTO to use its best
            efforts to obtain) the expiration or early termination of the
            applicable waiting period (or any extension thereof) for any
            required pre-acquisition or pre-merger notice to such authority, and
            will make (and Philips will cause OPTO to make) any further filings,
            including the submission of any additional information or
            documentary material, pursuant thereto that may be necessary in
            relation to such pre-acquisition or pre-merger notices and filings.

      (ii)  Prior to each Closing, Philips will (a) notify any and all Persons
            required to be notified by Philips in connection with the
            transactions to be consummated at such Closing, and (b) obtain any
            and all consents identified on Schedule 5.4 as required to be
            obtained by Philips prior to such Closing. From and after the OPTO
            Closing, Philips shall continue diligently to use its reasonable
            efforts to obtain all other consents identified on Schedule 5.4.

      (iii) Promptly after execution hereof, Uniphase and the Buyers will file
            (and Uniphase will cause the Buyers to file) any notification and

            without limitation, all filings and notifications under the HSR
            Act), will use its best efforts to obtain (and Uniphase will cause
            the Buyers to use their best efforts to obtain) the expiration or
            early termination of the applicable waiting period (or any extension
            thereof) for any required pre-acquisition or pre-merger notice to
            such authority, and will make (and Uniphase will cause the Buyers to
            make) any further filings, including the submission of any

                                                                              39


      (iv)  Prior to each Closing, the Uniphase Parties will (a) notify any and
            all Persons required to be notified by the Uniphase Parties in
            connection with the transactions to be consummated at such Closing,
            and (b) obtain any and all consents required to be obtained by the
            Uniphase Parties in connection with the transactions to be
            consummated at such Closing.

6.3.  Trade Unions and Works Counsel.

      Without limiting any of the obligations of Philips pursuant to Section
      6.2, prior to the Asset Sale Closing, Philips shall have (i) complied with
      all laws, rules and regulations of the Dutch Works Council Act applicable
      to the transactions contemplated by this Agreement and the other Sale
      Agreements, and (ii) obtained any and all approvals and consents required
      to be obtained therefrom and from any and all trade unions representing
      any of the OPTO Employees.

6.4.  Operation of the Activity.

      OPTO will not and Philips will not cause or permit OPTO to engage in any
      practice, take any action, embark on any course of inaction, or enter into
      any transaction outside the ordinary course of the Activity (except as
      described on Schedule 3.3), as the same is currently conducted or to do
      anything which would cause a material breach of the representations and
      warranties contained in Section 5.21, as if such representations and
      warranties were made at the time of such action or inaction. Philips shall
      cause OPTO to keep OPTO, the Activity and the Assets intact, including
      OPTO's physical facilities, working conditions and relationships with
      lessors, licensors, suppliers, customers and the OPTO Employees. Without
      limiting the generality of the foregoing, and except as approved in
      writing by Uniphase in advance, prior to the OPTO Closing, Philips will
      procure that OPTO: (a) will not enter nor allow to be entered into any
      agreements or commitments relating to the Activity (except as described on
      Schedule 3.3), except on commercially reasonable terms and in the ordinary
      course of business; (b) without limiting clause (a), will not enter into
      any license or otherwise grant any rights with respect to any of the
      Assets or the Intangible Assets other than in the connection with sales of

      (c) trade Indebtedness owed to Philips or its Affiliates, incurred in the
      ordinary course consistent with past practice.

6.7.  Notice of Developments.

      Each Party will give prompt written notice to the other of any material
      development affecting the financial or other condition of such Party or,
      with respect to Philips' obligations under this Section 6.7, the Activity.

6.8.  [Intentionally Omitted].

      in connection with (x) the transfer and the change of registration of the
      OPTO Patents by Philips as herein provided, and (y) the maintenance of the

8.1.  Retention of OPTO Employees.

      The Parties acknowledge that all OPTO Employees identified on Schedule
      5.12(a) will transfer by operation of law at the OPTO Closing.
      Notwithstanding the foregoing, Philips shall pay and be responsible for
      all salaries, wages and other compensation, and all severance, sick leave

      for in the Employee Benefit Plans) owed by OPTO and accrued with respect

      the Philips Parties to the OPTO Employees pursuant to the Employee Benefit

      with the terms and conditions of the 




<PAGE>   48

                                                                              43


      Dutch Philips Pension Fund. Philips has provided Uniphase with a true,
      correct and complete copy of the Dutch Philips Pension Fund organizational
      and governing documents.

8.3.  Collective Bargaining Agreement.

      The Parties acknowledge that, effective on the OPTO Closing Date, the OPTO
      Employees will not be covered by the Philips Collective Labour Agreement.
      The Philips Parties shall cooperate with the Uniphase Parties in good
      faith to procure a collective labour agreement, satisfactory to the
      Uniphase Parties, with respect to the OPTO Employees after the OPTO
      Closing Date.

8.4.  Transfer Expenses.

      All costs and expenses relating to the agreements of the Parties under
      this Section 8 shall be borne by the Uniphase Parties, other than Philips'
      obligations pursuant to Section 8.2, which shall be borne by Philips.


SECTION 9. POST-CLOSING COVENANTS

The Parties agree as follows with respect to matters arising following each
Closing.

9.1.  General.

      In case at any time after any Closing any further action is necessary to
      (i) perfect the transfer of ownership of the Consideration, the Intangible
      Assets or the OPTO Shares or the implementation in full of any of the Sale
      Agreements, or (ii) obtain any authorization, approval or consent of any
      Person required to consummate the transactions contemplated hereby (and
      which consent, authorization or approval was not required to be obtained
      prior to such Closing pursuant to the terms hereof), each Party will take
      such further action (including the execution and delivery of such further
      instruments and documents) as any other Party reasonably may request, all
      at the sole cost and expense of the requesting Party (unless the
      requesting Party is entitled to indemnification therefor under Section 10
      below), except with respect to the obtaining of consents described in
      clause (ii) above, the 




<PAGE>   49

                                                                              44


      cost of which shall be borne by the Party required to obtain such consent.
      In particular, but without limiting the generality of the foregoing, if it
      becomes apparent that any tangible or intangible asset used by OPTO or the
      Activity or required for use in the Activity is owned by Philips or any of
      Philips' Affiliates, Philips will or will procure that Philips' Affiliate
      will either transfer ownership of such asset to the relevant Buyer without
      charge or allow the relevant Buyer use of such asset indefinitely free of
      charge for the purposes of such Buyer's business; provided that the
      foregoing shall not apply to any of the assets on properties to be leased
      or otherwise made available to OPTO and/or Uniphase pursuant to the Lease
      or the Site Services Agreement.

9.2   Intellectual Property Rights and Obligations.

      (i)   After the OPTO Closing, subject to Section 9.3, Philips and, subject
            to the next sentence, Philips' Affiliates, shall have the
            nonexclusive, worldwide, royalty-free right to use the OPTO Patents,
            and the transfer of the OPTO Patents shall be further subject to
            Philips' commitments with respect to the same (which commitments
            consist solely of certain cross-licenses and Philips' obligations
            under the European R&D projects disclosed on Schedule 5.3) accruing
            prior to the date hereof. Notwithstanding the foregoing, if at any
            time any Philips Affiliate ceases to be a Philips Affiliate, the
            license rights provided in this Section 9.2(i) with respect to such
            Person shall immediately terminate and be of no further force or
            effect. Without Uniphase's prior written consent (which consent
            shall not be unreasonably withheld in the case of a sale by Philips
            of a product line or business division to Persons not competitive
            with Uniphase or its Affiliates), such license rights shall not be
            assignable, sublicensable or otherwise transferable, in whole or in
            part (by operation of law or otherwise).


      (ii)  Philips shall use reasonable endeavors, in cooperation with
            Uniphase, to ensure that, from and after the OPTO Closing Date, OPTO
            may continue to use all software used in the Activity. OPTO shall
            assume and be responsible for all costs in connection with license
            renewals for such software from and after the OPTO Closing Date as
            well as the maintenance costs of such 




<PAGE>   50

                                                                              45


            licenses from and after the OPTO Closing Date.

      (iii) After the OPTO Closing Date, OPTO shall no longer be entitled to use
            the "Philips" trademark (whether the "Philips" shield emblem or the
            word mark "Philips"), nor shall OPTO be entitled to use the trade
            name "Philips" (or "Phil" or "Phili" or any derivative thereof).
            Notwithstanding the foregoing, OPTO shall, for a period of one (1)
            year from and after the OPTO Closing Date, be entitled to use the
            "Philips" trade name or shield emblem, in a manner reasonably
            pre-approved by Philips, on remaining product manuals and packaging
            materials manufactured by or for OPTO prior to the OPTO Closing
            Date. Prior to the OPTO Closing Date, Philips shall procure that the
            trade name of OPTO be modified in such a manner that it no longer
            includes the name "Philips" (or any name including the elements
            "Phil" or "Phili") and shall effect such name change as requested by
            Uniphase in the relevant trade register.

      (iv)  Subject to Section 9.2(iii), neither Philips nor any of Philips'
            Affiliates shall, at any time from and after the OPTO Closing,
            assert against any of the Uniphase Parties, or any of their
            subsidiaries or Affiliates (and/or their respective customers), any
            patents owned or used by Philips or any of Philips' Affiliates, to
            the extent that such patents are used or incorporated in the design,
            manufacture, marketing, sale or use of any products (including all
            improvements or enhancements made to such products after the OPTO
            Closing Date, to the extent that such improvements or enhancements
            do not make use of any additional Intellectual Property owned or
            used by Philips and not used by the non-improved or non-enhanced
            product) produced by OPTO or the Activity or under development prior
            to the OPTO Closing Date. In addition and without limitation of the
            foregoing, to the extent OPTO shall be using Intellectual Property
            of Philips' or Philips' Affiliates, as of the OPTO Closing Date that
            is not subject to a patent and that is otherwise not being
            transferred to the Uniphase Parties pursuant to the Sale Agreements,
            the non-assertion obligations of Philips set forth in this Section
            9.2(iv) shall extend to and include any such non-patented
            Intellectual Property, other than Philips' proprietary software,
            with respect to which such non-assertion obligation shall apply only
            to OPTO, provided that to the extent OPTO is required by the terms
            of the Site Services Agreement or the Lease to pay for the use of




<PAGE>   51

                                                                              46


            any Philips proprietory software, the non-assertion with respect
            solely to such software shall terminate upon a default by OPTO
            (beyond any applicable cure period) with respect to any such
            payment.

9.3.  Non-Compete.

      For a period of five (5) years following the OPTO Closing Date, Philips
      and Philips' Affiliates shall not engage in the business of designing,
      developing, manufacturing or selling III-V semiconductor lasers or III-V
      monitor photodiodes. For the avoidance of doubt, the preceding sentence
      shall in no manner restrict Philips in conducting and continuing at any
      location the activities of other businesses, including, without
      limitation, the activities of the following entities: Philips Broadband
      Networks, Inc. in Manlius, New York, U.S.A.; Philips Optics /
      Electro-optical Components, part of Philips Components B.V. in Eindhoven,
      The Netherlands; Lumiled Lighting B.V. in Best, The Netherlands; Philips'
      microwave activities, part of Philips Semiconductors in Limeilles, France
      as well as in Caen, France; Philips Optical Storage Group in Eindhoven,
      The Netherlands; and the activities relating to communication systems for
      health care of Philips Medical Systems. In no event, however, shall the
      foregoing be deemed to permit Philips to effect commercial sales of any
      products being sold by or under development within the Activity as of the
      OPTO Closing Date.

9.4.  Closing Date Balance Sheet.

      Philips shall prepare and deliver the Closing Date Balance Sheet to
      Uniphase no later than the date that is forty-five (45) days after the
      OPTO Closing Date. The Closing Date Balance Sheet shall (i) be audited by
      KPMG Peat Marwick, Philips' auditors, and shall be prepared in a manner
      consistent with past practice, and (ii) conform to Philips' obligations
      pursuant to Section 6.6. The Closing Balance Sheet shall be certified by
      such auditors to Uniphase and Philips as complete and accurate in all
      respects and as showing the true and fair view of the state of affairs of
      OPTO and the Activity as at the OPTO Closing Date.

9.5.  Cooperation and Access to Financial Books and Records.

                                                                              47


      (i)   If required by Philips for the purpose of the preparation of tax
            filings and/or financial reporting (and responding to any Tax
            audits), Uniphase will provide all reasonable cooperation to
            Philips, at Philips' cost, in regard thereto. Such cooperation in
            any event includes that Uniphase, if so requested by Philips for
            this purpose, shall give access to all relevant books, relevant
            individuals and financial records relating to the Activity and OPTO
            and shall allow Philips to make copies thereof. Uniphase shall keep
            all of its books and records for all periods required by applicable
            law.

      (ii)  If required by Uniphase for the purpose of the preparation of tax
            filings and/or SEC and financial reporting (and responding to any
            Tax audits), Philips will provide all reasonable cooperation to
            Uniphase, at Uniphase's cost, in regard thereto. Such cooperation in
            any event includes that Philips, if so requested by Uniphase for
            this purpose, shall give access to all relevant books and financial
            records relating to the Activity and OPTO and shall allow Buyer to
            make copies thereof.

9.6.  Confidentiality.

      (i)   Philips will hold and cause its Affiliates to hold all information
            received under Section 9.5, and all other information that remains
            in the possession of Philips or Philips' Affiliates from any period
            prior to the OPTO Closing Date and that relates to the Activity, or
            the suppliers, Intellectual Property, technical know-how, customers,
            products and processes of OPTO, which are not in the public domain,
            in confidence and to use such information only for the purposes for
            which it was obtained, except that this Section 9.6 shall not
            restrict the use of information which is in the possession of
            Philips or Philips' Affiliates in their capacity as manufacturers,
            purchasers or suppliers conducting businesses other than the
            Activity as conducted by them prior to the date hereof.

      (ii)  Each Party agrees to forever hold and to cause its Affiliates to
            hold all information received from any other Party, and which is not
            in the public domain, in strict confidence, except to the extent
            disclosure of such information is required by applicable law.

9.7.  Press Releases and Other Disclosures.

      No Party or such Party's Affiliates, without the prior written consent of
      the other Party, will issue any press release or any similar public
      announcement concerning the transactions contemplated by this Agreement,
      such consent not to be unreasonably delayed or withheld. However, if such
      disclosure is required by law or regulations of a stock exchange or other
      regulatory body, no such consent shall be required, and the Parties will
      cooperate in preparing a press release or releases.

9.8.  Poaching.

      During the two (2) year period following the OPTO Closing, Philips will
      and will procure that each of Philips' Affiliates will not solicit any of
      the OPTO Employees for employment. For the purposes of this Section
      'solicit' shall include any act intended or calculated to result in an
      OPTO Employee leaving the employment of OPTO or Uniphase or its
      subsidiaries but shall exclude any of the following activities by Philips
      or its Affiliates:

      (i)   advertising for employment in any bulletin board (including
            electronic bulletin boards), newspaper, trade journal or other
            publication available to the general public;

      (ii)  participating in any hiring fair or similar event open to the public
            and not targeted at employees of any Uniphase or its subsidiaries;

      (iii) use of recruiting or employee search firms that have been instructed
            and agreed in writing not to solicit any OPTO Employee; and

      (iv)  negotiating with and/or offering employment to any OPTO Employee who
            initially contacts Philips or an Affiliate solely as a result of any
            of the activities included in clauses (i) to (iii) above.




<PAGE>   54

                                                                              49


      Philips agrees that it and Philips' Affiliates may only employ an OPTO
      Employee if neither it nor any Philips' Affiliate has solicited such OPTO
      Employee in contravention of clauses (i) to (iii) above.


SECTION 10. INDEMNITIES

10.1. Indemnities by Philips.

      Philips undertakes with the Uniphase Parties to indemnify and hold each of
      the Uniphase Parties harmless against all Claims arising out of or
      incurred as a result of any breach by Philips of (i) any representation or
      warranty of Philips contained in this Agreement or any of the other Sale
      Agreements, or (ii) any covenant, agreement or obligation of Philips under
      this Agreement or any of the other Sale Agreements.

10.2. Indemnities by Uniphase.

      Uniphase undertakes with Philips to indemnify and hold Philips harmless
      against all Claims arising out of or incurred as a result of any breach by

      the Uniphase Parties under this Agreement or any of the other Sale
      Agreements.

10.3. Defense of Claims.

            respect to which a Party (the "Indemnified Party") is entitled to be
            indemnified pursuant to Section 10.1 or 10.2 above, the Party
            required to indemnify the Indemnified Party (the "Indemnifying
            Party") shall reasonably promptly, following the Indemnified Party's
            actual knowledge thereof, notify the Indemnifying Party of such
            Claim. The Indemnifying Party shall have the right to assume the
            defense of such Claim at the sole expense of the Indemnifying Party.

            such Claim:

                                                                              50


            (a)   the Indemnifying Party shall proceed to defend such Claim in a

                  Indemnified Party;

            (b)   the Indemnifying Party shall keep the Indemnified Party

            (d)   the Indemnifying Party shall not settle, adjust or compromise
                  such Claim without the prior written consent of the
                  Indemnified Party, which consent shall not be unreasonably

            the event that the OPTO Closing shall not have occurred by June 30,
            1998, provided that the failure of the OPTO Closing to occur is not
            due to the breach by the terminating Party of any provision of this
            Agreement.

11.2. Limitations on Philips' Termination Rights.

      Notwithstanding anything to the contrary set forth in Section 11.1(v)
      above, Philips may not terminate this Agreement if, at the election of the

      adjusted as follows: (a) the non-cash portion of the Consideration paid at
      the OPTO Closing shall be calculated based on a price per Uniphase Common
      Share of U.S.$60.00, or (b) in lieu of the foregoing, in addition to the
      Consideration (calculated without regard to clause (a) above), Uniphase

<PAGE>   57

                                                                              52

      calculate the Consideration), equal to the sum of (x) the product of (1)
      the Average Closing Market Price minus U.S.$60.00, multiplied by (2) the
      number of Uniphase Common Shares included in the Consideration, plus (y)
      an amount such that, on an after tax basis, Philips receives the same
      value of consideration pursuant to clause (b) as it would have received
      under clause (a).

11.3. Effect of Termination.

      Except for Sections 9.6, 9.7 and 10, which Sections shall survive any
      termination of this Agreement, in the event of any termination of this
      Agreement pursuant to Section 11.1, this Agreement shall immediately
      terminate and be of no further force or effect, and the Parties shall be
      released from any and all obligations hereunder, provided that, nothing
      herein shall relieve any Party from liability for the breach of any
      representation, warranty, covenant or agreement of such Party set forth in
      this Agreement, or such Party's indemnity obligations with respect to such
      breach.


SECTION 12. REMEDIES FOR BREACHES OF THIS AGREEMENT

12.1. Survival.

      All representations and warranties of the Parties contained in this
      Agreement shall survive each Closing and continue in effect for the
      following periods:

      (i)   Except as otherwise provided in this Section 12.1, the
            representations and warranties in Sections 4 and 5 shall expire
            eighteen (18) months after the OPTO Closing Date;

      (ii)  The representations and warranties of the Uniphase Parties and

<PAGE>   58

                                                                              53


      (iv)  the representations and warranties of Philips under Section 5.14
            shall expire ten (10) years after the OPTO Closing Date;

      and each Party must assert any Claim involving a representation and
      warranty against the other Party by providing notice in accordance with
      Section 13.3, specifying the factual basis in reasonable detail, before
      expiration of any applicable survival period. Notwithstanding any contrary
      provision, as long as the Claim is asserted on a timely basis, the Claim
      will continue to be valid and assertible even though the survival period
      may subsequently expire before the Claim is resolved.

12.2. Liability of Philips.

      Subject to the next sentence, (a) in the absence of fraud, Philips'
      aggregate liability to the Uniphase Parties, pursuant to this Agreement
      and the other Sale Agreements (other than the Lease and the Site Services
      Agreement), shall not exceed NLG 50 million, and (b) Philips shall have no
      liability under such Sale Agreements unless the aggregate amount of all of
      the Uniphase Parties' Claims exceeds NLG 1 million, in which event,
      Philips shall be liable for all Claims, which exceed NLG 50,000 (provided
      that claims of a similar nature or involving a single Person (and its
      Affiliates) shall be aggregated for the purpose of determining such NLG
      50,000 amount). Notwithstanding the foregoing, (x) the maximum aggregate
      liability of Philips for any breach of Section 9.3 shall be NLG 50
      million, independent of any limit prescribed in the preceding sentence
      (provided that the amount of any indemnification claims for breach of
      Section 9.3 shall be counted against the NLG 50 million limit on liability
      set forth in the preceding sentence), and (y) the maximum aggregate
      liability of the Philips Parties for any breach by them of their
      representations and warranties under Sections 5.2, 5.6, 5.10(i) and
      5.10(v) shall be NLG 462 million, independent of any limit prescribed in
      the preceding sentence.


12.3. Liability of Uniphase Parties.

      In the absence of fraud, the Uniphase Parties' aggregate liability to
      Philips, pursuant to this Agreement and the other Sale Agreements (other
      than the Lease and the Site Services Agreement), shall not exceed NLG 50
      million. In addition, the Uniphase Parties shall have no liability under
      such Sale Agreements unless the 




<PAGE>   59

                                                                              54


      aggregate amount of all of the Philips Parties' Claims exceeds NLG 1
      million, in which event, subject to the next sentence, the Uniphase
      Parties shall be liable for all Claims which exceed NLG 50,000 (provided
      that claims of a similar nature or involving a single Person (and its
      Affiliates) shall be aggregated for the purpose of determining such NLG
      50,000 amount). Notwithstanding the foregoing, the maximum aggregate
      liability of Uniphase for any breach of its obligations pursuant to the
      Series A Preferred Agreement (and the corresponding provisions in the
      Certificate of Designation) shall be NLG 200 million, without prejudice to
      Uniphase's obligation to pay the Earn-Out (as defined therein), but
      subject to a credit for any such damage amount against the maximum amounts
      payable for such Earn-Out, if applicable.

12.4. Other Liability Provisions.

      The foregoing liability provisions are in lieu of any statutory or common
      law remedy a Party may have for breach of any representation, warranty or
      covenant of this Agreement or the other Sale Agreement (other than the
      Lease and the Site Services Agreement).

                               GENERAL DISCLOSURE


GENERAL

Any disclosure made hereunder, or under any of the Schedules attached hereto,
will be deemed to have been made also in relation to any other Section of this
Agreement to which it may be relevant.

As of the date hereof, the Uniphase Parties are not aware of any facts, events
or circumstances which would cause any of the representations and warranties as
provided by Philips hereunder to be untrue in any material respect.

As of the date hereof, Philips is not aware of any facts, events or
circumstances which would cause any of the representations and warranties as
provided by any of the Uniphase Parties hereunder to be untrue in any material
respect.


INTELLECTUAL PROPERTY RIGHTS

Reference is made to the fact that Rockwell Corporation has in the past notified
Philips in relation to a possible infringement by Philips of certain Rockwell
patents. Philips has also been notified of the possible infringement by Philips
of a patent owned by the Massachusetts Institute of Technology (M.I.T.).

In general, OPTO will, from Closing, no longer be covered under any of the
current Philips cross licence agreements entered into with third parties in
respect of intellectual property rights (notably patents). By contrast, the
change of control of Philips Optoelectronics B.V. will not affect the rights of
Philips' cross licensing partners under the relevant cross licensing agreements,
even after the transfer of the OPTO Patents.


ENVIRONMENTAL MATTERS

Reference is made to the fact that currently, for the disposal of carbon
filters, containing arsine, no arrangement is in place with Mirec B.V. or any
other third party having a licence to accept such materials for disposal.
However, the contract with Mirec B.V. (disclosed under Schedule 5.13) does
provide for the disposal of other waste.


INSURANCE

From Closing, Philips Optoelectronics will no longer be covered under any of
Philips insurance policies.


                                       1
<PAGE>   66

VAT REGISTRATION

From Closing, Philips Optoelectronics will have to apply for separate VAT
registration, in its own name, as a result of the fact that it will no longer
form part of the fiscal unity of Nederlandse Philips Bedrijven B.V.


CORPORATE PURCHASING ARRANGEMENTS

From Closing, Philips Optoelectronics will no longer participate under any
corporate purchasing arrangements (including IT licence agreements) of Philips.

               Prior to the Asset Sale Closing Date, Philips shall cause OPTO to

Philips Party of the Consideration or any amounts paid or distributed to Philips
or the Philips Parties with respect to the Uniphase Preferred Stock to be issued

                                NONCONTRAVENTION


CHANGE OF CONTROL PROVISIONS IN CONTRACTS

Uniphase Corporation is hereby notified of the fact that the software licence
agreements and the software services agreements under which Philips
Optoelctronics participates may contain so-called change of control provisions
pursuant to which the other party has the right to terminate the agreement in
event of a change of control in Philips Optoelectronics B.V. Reference is made
to the list of Material Contracts, disclosed under Schedule 5.19; certain of
these Material Contracts contain such change of control provisions. All such
change in control provisions as contained in any of these Material Contracts are
identified as required consents on Schedule 5.4.


EXPORT LICENCE

Philips Optoelectronics B.V. will, as result of the change of control, no longer
be covered under the general export licence of Nederlandse Philips Bedrijven
B.V. in respect of so-called strategic goods.

This general export licence has been granted by the Centrale Dienst voor In- en
Uitvoer in Groningen, The Netherlands (copy of licence disclosed under section
3.3 of the initial due diligence binders). As a result, Philips Optoelectronics
B.V. will have to apply with said authority for an export licence in respect of
strategic goods in its own name.


EUROPEAN R & D PROJECTS

Philips Optoelectronics currently participates under a number of European R&D
projects, which are sponsored by the European Community. This participation is
formally in the name of Nederlandse Philips Bedrijven B.V., as the contracting
legal entity.

The other partners under these projects, as well as the European Commission have
to be notified of the fact that Philips Optoelctronics is now established as a
separate legal entity as well as of the imminent change of control in Philips
Optoelectronics B.V.

In principle, as result of such change of control of Philips Optoelectronics
B.V., the participation of Philips Optoelectronics under these projects will be
discontinued.

In the event that Philips Optoelectronics would wish to continue its
participation under said projects, it would need to obtain the approval from the
relevant partners under these projects as well as the confirmation from the
European Commission.



                                       8
<PAGE>   73

In the event of discontinuation of the participation of Philips Optoelectronics
under any of these R & D projects, such discontinuation will also imply that
Philips Optoelectronics will no longer have necessary background information of
Philips as contributed under these projects, will be continued. Reference is
made to the document setting out the rules and procedures regarding Philips'
participation under European R & D projects, notably to Annex II of the General
Conditions of the so-called Esprit Programme, copy of which has been provided to
Uniphase in the course of the interview with Mr. E. Ideler on May 13, 1998, as
part of the confirmatory due diligence survey by Uniphase.


INTELLECTUAL PROPERTY RIGHTS

As stated in the general disclosure letter, as a result of the change of control
in Philips Optoelectronics B.V., Philips Optoelectronics B.V. will no longer be
covered under the so-called cross licence agreements with third parties (in
respect of patents (and other intellectual property rights, as the case may be)
as entered into by Philips. By contrast, the rights of Philips' cross-licensing
partners under the relevant cross-licensing agreements will not be affected by
the change of control in Philips Optoelectronics B.V. or by the transfer of the
OPTO Patents to Uniphase.

                                    CONSENTS


A.      Required:

1.      Hart-Scott-Rodino filing

Philips is required to submit a so-called Hart-Scott-Rodino filing in respect of
the contemplated transaction under the so-called Hart-Scott-Rodino Antitrust
Improvements Act of 1976. Such filing has been made.

2.      Works council/Unions

The change of control in Philips Optoelectronics B.V. is subject to the
provisions of the Dutch Works Councils Act (Wet op de Ondernemingsraden).
Pursuant to Article 25 of said Act, the relevant works council needs to give a
positive advice in respect of the contemplated transaction and the related
consultation procedure with the relevant works council is to be initiated as
soon as there is a legitimate expectation between the prospective partners that
agreement regarding the intended transaction can be reached. At the time of the
signing of the Letter of Intent regarding the contemplated transaction however,
no separate works council was yet in place for Philips Optoelectronics, as a
result of the fact that Philips Optoelectronics had only been incorporated as a
separate legal entity in February 1998. Given the fact that no separate works
council was yet in place for Philips Optoelectronics B.V. at the time of the
signing of the letter, and in order to comply with the spirit of the Works
Councils Act, Philips has requested the advice regarding the contemplated
transaction from an ad hoc committee, comprising representatives for Philips
Optoelectronics and members from the works council of the Philips Research
Laboratories, of which Philips Optoelectronics was part prior to its
incorporation as a separate legal entity. In addition, negotiations with the
relevant unions were initiated regarding the labour conditions as would apply
after the transition, including possible transition measures. The negotiations
with the unions have been concluded satisfactorily and positive advice regarding
the contemplated transaction has been obtained from the ad hoc committee and the
works council of Philips Optoelectronics per letter dated 26th May, 1998, copy
of which is attached hereto.

3.      Change of control provisions in Material Contracts

Philips Optoelectronics has written to the third parties specified above to
solicit their consent in connection with the relevant transfer, on May 27, 1998.
Attached hereto are copies of the responses received from these third parties.

Pursuant to Item 601(b)(2) of Regulation S-K, this portion of this Schedule to
the Master Purchase Agreement has been omitted. The omitted portion of the
Schedule will be submitted to the Securities and Exchange Commission upon
request.

B.      Other:

1.      European R & D projects

Reference is made to Schedule 5.3. As set out herein, the consent from the
relevant partners under the European R&D projects is required for the continued
participation of Philips Optoelectronics B.V. under the relevant European R&D
projects; similar consent/confirmation is required from the European Commission.

In connection with the incorporation of Philips Optoelectronics B.V. as a
separate legal entity, the relevant contract partners of Philips Optoelectronics
need to consent to the transition, i.e. the incorporation of Philips
Optoelectronics B.V. as a separate legal entity (formally contracting through
Nederlandse Philips Bedrijven B.V). The relevant contract partners (suppliers as
well as customers) have been notified in writing of said incorporation; no
adverse reaction has been received and no indication has been received that any
adverse reaction is to be expected. However, the Philips refrains from any
representation or warranty as to such consents from the relevant contract
partners.

Philips Optoelectronics B.V. does not own all assets used in the operation of
its activities. Attached hereto is a listing of equipment currently leased from
Philips Research (Nat Lab), part of Nederlandse Philips Bedrijven B.V. Pursuant
to Item 601(b)(2) of Regulation S-K, this portion of the Schedule has been
omitted. The omitted information will be submitted to the Securities and
Exchange Commission upon request.

A listing of real property/buildings leased by Philips Optoelectronics B.V. is
attached to Schedule 5.9.

In respect of Section 5.6 (ii), it should be noted that not all raw materials,
work in progress and finished goods existing at the OPTO Closing Date
necessarily comply with the applicable specifications so as to enable them to be
sold in the ordinary course of business. However, a portion of such raw
materials, work in progress and finished goods, although not complying with the
applicable specifications, has been valued on the balance sheet on the basis of
the expectation that they can still be sold in the ordinary course of business.
Conversely, any raw materials, work in progress and/or finished goods which do
not comply with the applicable specifications and which can which are not
included in the sales forecasts, are not included on the balance sheet of
Philips Optoelectronics.

incorporation of substantial information by reference to other documents filed
by Uniphase with the SEC.

Exchange Commission.


         2.       REGISTRATION; RESTRICTIONS ON TRANSFER

                  2.1.     Restrictions on Transfer of Voting Stock

                           2.1.1.   Philips shall not, directly or indirectly, 
sell, assign, pledge, hypothecate or otherwise transfer any shares of the
Closing Common Stock (or any right, title or interest therein) for a period of
one year following the date hereof.

                           2.1.2. Any purported transfer in violation of this
Section 2.1 shall be void.

                           2.1.3.   Each certificate representing Registrable 
Securities shall (unless otherwise permitted by the provisions of the Agreement)
be stamped or otherwise imprinted with a legend substantially similar to the

laws, Uniphase's bylaws, or as provided elsewhere in this Agreement):

                  THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
            UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED,
            SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED
            UNLESS AND UNTIL REGISTERED UNDER THE ACT OR UNLESS UNIPHASE HAS
            RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO UNIPHASE AND ITS
            COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED.

                                                                               4


                           2.1.4.   Uniphase shall be obligated to reissue 
promptly unlegended certificates at the request of any holder thereof if the
holder shall have obtained an opinion of counsel (which counsel may be counsel
to Uniphase) reasonably acceptable to Uniphase to the effect that the securities
proposed to be disposed of may lawfully be disposed of without registration,
qualification or legend.

                  2.2.     Demand Registrations

                           2.2.1.   Right to Demand Registration. Subject to the
conditions of this Section 2.2, if Uniphase shall receive a written request from
the Holders of Registrable Securities (the "Initiating Holders") that Uniphase
file a registration statement under the Securities Act covering the registration
of Registrable Securities then outstanding having a Market Value of not less
than $10,000,000, then Uniphase shall, within thirty (30) days of the receipt of
such request, give written notice of such request to all Holders, and subject to
the limitations of this Section 2.2, effect, as soon as practicable, the
registration under the Securities Act of all Registrable Securities that the
Holders request to be registered.

                           2.2.2.   Underwriting.  If the Initiating Holders 
intend to distribute the Registrable Securities covered by their request by
means of a firm commitment underwritten offering, they shall so advise Uniphase
as part of their request made pursuant to this Section 2.2, and Uniphase shall
include such information in the written notice referred to in Section 2.2.1. The
Initiating Holders shall designate any underwriter or underwriters to be
retained in connection with any registration pursuant to this Section 2.2, which
underwriter or underwriters shall be reasonably acceptable to Uniphase. In such
event, the right of any Holder to include its Registrable Securities in such
registration shall be conditioned upon such Holder's participation in such
underwritten offering and the inclusion of such Holder's Registrable Securities
in the underwriting (unless otherwise mutually agreed by a majority in interest
of the Initiating Holders and such Holder) to the extent provided herein. All
Holders proposing to distribute their securities through such underwriting and
Uniphase, shall enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such underwriting. Notwithstanding any
other provision of this Section 2.2, if the underwriter in good faith advises
Uniphase that marketing factors require a limitation of the number of securities
to be underwritten (including Registrable Securities) then any securities to be
sold on behalf of Uniphase or any stockholder of Uniphase (other than Holders)
shall be excluded from such registration to the extent required by such
limitation. If a limitation on the number of shares to be included in such
registration shall still be required after giving effect to the limitation in
the preceding sentence, Uniphase shall so advise all Holders of Registrable
Securities which would otherwise be underwritten pursuant hereto, and the number
of shares that may be included in the underwriting shall be allocated to the
Holders of such Registrable Securities on a pro rata basis based on the number
of Registrable Securities held by all such Holders (including the Initiating
Holders). Any Registrable Securities excluded or withdrawn from such
underwriting shall be withdrawn from the registration. In the event that the
reduction in Registrable Securities to be included in such registration reduces
the number of Registrable Securities to be so registered to less than fifty
percent (50%) of the Registrable Securities requested to be so registered
pursuant to this Section 2.2, Uniphase shall be obligated to proceed with the
registration and such

                                                                               5


registration shall not be counted for the purpose of clause (2) or (3) of
Section 2.2.3 below. If any Holder disapproves of the terms of the underwritten
offering, it may elect to withdraw therefrom by prompt written notice to
Uniphase, the underwriter and the Initiating Holders. The Registrable Securities
so withdrawn shall also be withdrawn from registration. Subject to the foregoing
limitations and Section 2.2.4, Uniphase shall have the right to include
securities to be sold on its behalf in any offering registered pursuant to this
Section 2.2.

                           2.2.3.   Uniphase shall not be required to effect a 
registration pursuant to this Section 2.2:

                                    1.      prior to one (1) year from the date 
of this Agreement, provided that a holder may give notice and require that the
Company take steps necessary to ensure that such registration is effective upon
the first anniversary of this Agreement; or'

                                    2.      after any holder has demanded three 
(3) registrations pursuant to this Section 2.2, and such registrations have been
declared or ordered effective; or

                                    3.      after any Holder has demanded one 
(1) registration pursuant to this Section 2.2 during the preceding twelve (12)
month period, and such registration has been declared or ordered effective.

                           2.2.4.   Exclusivity.  If the Initiating Holders do 
not advise Uniphase of their intent to distribute the Registrable Securities
covered by their request by means of a firm commitment underwritten offering,
they shall have the right to require that Uniphase not register any additional
shares or allow any other registration statement to become effective, whether on
that registration statement or otherwise (other than a registration on Form S-8,
Form S-4 or any successor to such forms), for a period not to exceed 30 days
after effectiveness of the registration statement on which the Initiating
Holders' shares are being registered. Such right to demand exclusivity shall
preclude any other person from exercising piggy-back registration rights similar
to Section 2.3.

                  2.3.      Piggyback Registrations. Uniphase shall notify all 
Holders of Registrable Securities in writing promptly but in any event at least
twenty (20) days prior to the initial filing of any registration statement under
the Securities Act to register any of its securities either for its own account
or the account of any holder or holders of Uniphase equity securities, but
excluding registration statements relating to employee benefit plans or with
respect to corporate mergers, combinations, acquisitions, reorganizations or
other transactions under Rule 145 of the Securities Act) and will afford each
such Holder an opportunity to include in such registration statement (and any
related qualification under blue sky laws or other compliance), and in any
underwritten offering therein all or part of such Registrable Securities held by
such Holder. Each Holder desiring to include in any such registration statement
all or any part of the Registrable Securities held by it shall, within fifteen
(15) days after the above-described notice from Uniphase, so notify Uniphase in
writing. Such notice shall state the intended method of disposition of the
Registrable Securities by such Holder. If a Holder decides not to include all of
its Registrable Securities in any registration statement thereafter filed by
Uniphase, such Holder shall

                                                                               6


nevertheless continue to have the right to include any Registrable Securities in
any subsequent such registration statement or registration statements pursuant
to this Section 2.3.

                           2.3.1.   Underwriting.  If the registration statement
under which Uniphase gives written notice under this Section 2.3 is for an
underwritten offering, Uniphase shall so advise the Holders of Registrable
Securities in such written notice. In such event, the right of any such Holder
to be included in a registration pursuant to this Section 2.3 shall be
conditioned upon such Holder's participation in such underwritten offering and
the inclusion of such Holder's Registrable Securities in the underwritten
offering to the extent provided herein. All Holders proposing to distribute
their Registrable Securities through such underwritten offering and Uniphase
shall enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such underwriting by Uniphase.
Notwithstanding any other provision of the Agreement, if the underwriter
determines that marketing factors require a limitation of the number of shares
to be underwritten, the securities of Uniphase (other than Registrable
Securities) held by officers or directors and by other shareholders (other than
shareholders holding Pari Passu Registration Rights (as hereinafter defined)
(the "Pari Passu Holders"), shall be excluded from such registration to the
extent so required by such limitation, and if a limitation of the number of
shares is still required, then the underwriter may limit the number of
Registrable Securities and securities held by Pari Passu Holders to be included
in the registration, such limitation to be allocated pro rata among the Holders
and the Pari Passu Holders based on the number of Registrable Securities and
securities held by Pari Passu Holders otherwise requested to be included in such
registration. No such reduction shall reduce the securities being offered by
Uniphase for its own account to be included in the registration and
underwriting. If any Holder disapproves of the terms of the underwritten
offering, it may elect to withdraw therefrom by prompt written notice to
Uniphase and the underwriter. The Registrable Securities so withdrawn shall also
be withdrawn from registration.

                           2.3.2.   Right to Terminate Registration. Uniphase 
shall have the right to terminate or withdraw any registration initiated by it
under this Section 2.3 prior to the effectiveness of such registration whether
or not any Holder has elected to include securities in such registration. The
Registration Expenses of such withdrawn registration shall be borne by Uniphase
in accordance with Section 2.5 hereof.

                  2.4.     Form S-3 Registration. In case Uniphase shall receive
from any Holder or Holders of Registrable Securities then outstanding, having a
Market Value of not less than $5,000,000, a written request or requests that
Uniphase effect a registration on Form S-3 or any similar short-form
registration statement and any related qualification or compliance with respect
to Registrable Securities, Uniphase will:

                           2.4.1.   promptly give written notice of the proposed
registration, and any related qualification or compliance, to all other Holders
of Registrable Securities; and

                           2.4.2.   as soon as practicable, use its best efforts
to effect such registration and all such qualifications and compliances as may
be so requested and as would permit or facilitate the sale and distribution of
all or such portion of such Holder's or Holders' Registrable 




<PAGE>   7

                                                                               7


Securities as are specified in such request, together with all or such portion
of the Registrable Securities of any other Holder or Holders joining in such
request as are specified in a written request given within fifteen (15) days
after receipt of such written notice from Uniphase, provided, however, that
Uniphase shall be obligated to file a registration statement no later than one
hundred twenty (120) days after receipt of a request under this Section 2.4.

                           2.4.3.   Notwithstanding anything herein to the 
contrary, Uniphase shall not be obligated to effect any such registration,
qualification or compliance pursuant to this Section 2.4:

                                    1.       To the extent Form S-3 (or any 
successor or similar form) is not available for such offering by the Holders; or

                                    2.       if the Holders propose to sell 
Registrable Securities and such other securities (if any) with a Market Value of
less than $2,500,000; or

                                    3.       if Uniphase has, within the twelve 
(12) month period preceding the date of such request, already effected one (1)
registration on Form S-3 for the Holders pursuant to this Section 2.4.

                           2.4.4.   Underwriting.  If the Holders intend to 
distribute the Registrable Securities covered by their request by means of a
firm commitment underwriting, they shall so advise Uniphase as a part of their
request made pursuant to this Section 2.4, and Uniphase shall include such
information in the written notice referred to in Section 2.4.1. The Holders
shall designate any underwriter or underwriters to be retained in connection
with any registration pursuant to this Section 2.4, which underwriter or
underwriters shall be reasonably acceptable to Uniphase. In such event, the
right of any Holder to include its Registrable Securities in such registration
shall be conditioned upon such Holder's participation in such underwriting and
the inclusion of such Holder's Registrable Securities in the underwriting
(unless otherwise mutually agreed by a majority in interest of the Initiating
Holders and such Holder) to the extent provided herein. Uniphase and all Holders
proposing to distribute their securities through such underwriting shall enter
into an underwriting agreement in customary form with the underwriter or
underwriters selected for such underwriting.

                           2.4.5.   Subject to the foregoing, Uniphase shall 
file a Form S-3 registration statement covering the Registrable Securities and
no other securities as soon as practicable after receipt of the request or
requests of the Holders, but in no event later than 120 days from the receipt of
such request.

                  2.5. Expenses of Registration. Except as specifically provided
herein, all Registration Expenses incurred in connection with any registration,
qualification or compliance pursuant to Section 2.2, Section 2.3 or Section 2.4
herein shall be borne by Uniphase. All Selling Expenses incurred in connection
with any registrations hereunder, shall be borne by the holders of the
securities so registered pro rata on the basis of the number of shares so
registered. Uniphase shall not, however, be required to pay for expenses of any
registration proceeding

                                                                               8


begun pursuant to Section 2.2, the request of which has been subsequently
withdrawn by the Initiating Holders unless the withdrawal is pursuant to Section
2.7. If the Holders are required to pay the Registration Expenses, such expenses
shall be borne by the holders of securities (including Registrable Securities)
requesting such registration in proportion to the number of shares for which
registration was requested and such Holders shall not forfeit their rights
pursuant to Section 2.2 to demand registration. If Uniphase is required to pay
the Registration Expenses of a withdrawn offering (other than pursuant to
Section 2.7), then the Holders shall forfeit their rights pursuant to Section
2.2 to one demand registration.

                  2.6.     Obligations of Uniphase. Whenever required to effect 
the registration of any Registrable Securities, Uniphase shall, at its expense,
as expeditiously as reasonably possible:

                           2.6.1.   Prepare and file with the SEC a registration
statement with respect to such Registrable Securities and use all reasonable
efforts to cause such registration statement to become effective, and keep such
registration statement effective for up to one hundred and twenty (120) days (or
two (2) years, if such registration is pursuant to Section 2.4 hereof) days or,
if earlier, until the Holder or Holders have completed the distribution related
thereto.

                           2.6.2.   Prepare and file with the SEC such 
amendments and supplements to such registration statement and the prospectus
used in connection with such registration statement as may be necessary to
comply with the provisions of the Securities Act with respect to the disposition
of all securities covered by such registration statement.

                           2.6.3.   Furnish to the Holders such number of copies
of a prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Registrable
Securities owned by them.

                           2.6.4.   Use all reasonable efforts to register and 
qualify the securities covered by such registration statement under such other
securities or Blue Sky laws of such jurisdictions as shall be reasonably
requested by the Holders.

                           2.6.5.   In the event of any underwritten public 
offering, enter into and perform its obligations (including reasonable
indemnification) under an underwriting agreement, in usual and customary form,
with the managing underwriter(s) of such offering. Each Holder participating in
such underwriting shall also enter into and perform its obligations under such
an agreement.

                           2.6.6.   Notify each Holder of Registrable Securities
covered by such registration statement at any time when a prospectus relating
thereto is required to be delivered under the Securities Act of the happening of
any event as a result of which the prospectus included in such registration
statement, as then in effect, includes an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary to
make

                                                                               9


the statements therein not misleading in the light of the circumstances then
existing.

                           2.6.7.   Furnish, at the request of a majority in 
interest of the Holders participating in the registration, on the date that such
Registrable Securities are delivered to the underwriters for sale, if such
securities are being sold through underwriters, or, if such securities are not
being sold through underwriters, on the date that the registration statement
with respect to such securities becomes effective, (i) an opinion, dated as of
such date, of the counsel representing Uniphase for the purposes of such
registration, in form and substance as is customarily given to underwriters in
an underwritten public offering and reasonably satisfactory to a majority in
interest of the Holders requesting registration, addressed to the underwriters,
if any, and to the Holders requesting registration of Registrable Securities,
and (ii) a letter dated as of such date, from the independent certified public
accountants of Uniphase, in form and substance as is customarily given by
independent certified public accountants to underwriters in an underwritten
public offering and reasonably satisfactory to a majority in interest of the
Holders requesting registration, addressed to the underwriters, if any, and if
permitted by applicable standards governing such accountants, to the Holders
requesting registration of Registrable Securities.

                  2.7.     Delay in Registration. Uniphase shall have the right 
to delay the filing or effectiveness of any registration statement contemplated
by Section 2.2, 2.3 or 2.4 for one or more periods, aggregating not more than
sixty (60) days in any twelve month period, in the event that (i) Uniphase
would, in accordance with the written advice of its legal counsel, be required
to disclose in the prospectus information not otherwise then required by law to
be publicly disclosed and (ii) in the reasonable judgment of the Uniphase's
Board of Directors, there is a reasonable likelihood that such disclosure would
materially and adversely affect any existing or prospective material business
situation, transaction or negotiation or otherwise materially and adversely
affect Uniphase.

                  2.8.     Termination of Registration Rights. A Holder's 
registration rights shall expire at such time as all Registrable Securities held
by such Holder can reasonably be expected to be able to be sold under Rule 144
under the Securities Act during any ninety (90) day period.

                  2.9.     Delay of Registration; Furnishing Information

                           2.9.1.   No Holder shall have any right to obtain or 
seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 2.

                           2.9.2.   It shall be a condition precedent to the 
obligations of Uniphase to take any action pursuant to Section 2.2, 2.3 or 2.4
that the selling Holders shall furnish to Uniphase such information regarding
themselves, the Registrable Securities held by them and the intended method of
disposition of such securities as shall be required to effect the registration
of their Registrable Securities.

                                                                              10


                  2.10.    Indemnification. In the event any Registrable
Securities are included in a registration statement under Sections 2.2, 2.3 or
2.4:

                           2.10.1.  To the extent permitted by law, Uniphase 
will indemnify and hold harmless each Holder, the partners, members, officers,
directors and legal counsel of each Holder, any underwriter (as defined in the
Securities Act) for such Holder and each person, if any, who controls such
Holder or underwriter within the meaning of the Securities Act or the Exchange
Act, against any losses, claims, damages, or liabilities (joint or several) to
which they may become subject under the Securities Act, the Exchange Act or
other federal or state law, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
of the following statements, omissions or violations (collectively a
"Violation") by Uniphase: (i) any untrue statement or alleged untrue statement
of a material fact contained in any registration statement, including any
preliminary prospectus or final prospectus contained therein or any amendments
or supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading, or (iii) any violation or alleged violation by Uniphase
of the Securities Act, the Exchange Act, any state securities law or any rule or
regulation promulgated under the Securities Act, the Exchange Act or any state
securities law and related to any action or inaction required of Uniphase in
connection with the offering covered by such registration statement; and
Uniphase will reimburse each such Holder, partner, member, officer or director,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action; provided however, that the indemnity
agreement contained in this Section 2.10.1 shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of Uniphase, which consent shall not
be unreasonably withheld, nor shall Uniphase be liable in any such case for any
such loss, claim, damage, liability or action to the extent that it arises out
of or is based upon a Violation which occurs in reliance upon and in conformity
with written information furnished expressly for use in connection with such
registration by such Holder, partner, member, officer, director, underwriter or
controlling person of such Holder.

                           2.10.2.  To the extent permitted by law, each Holder 
will, if Registrable Securities held by such Holder are included in the
securities as to which such registration qualifications or compliance is being
effected, indemnify and hold harmless Uniphase, each of its directors, its
officers, and legal counsel and each person, if any, who controls Uniphase
within the meaning of the Securities Act, any underwriter, any person who
controls such underwriter, and any other Holder selling securities under such
registration statement or any of such other Holder's partners, members,
directors or officers or any person who controls such other Holder, against any
losses, claims, damages or liabilities (joint or several) to which they may
become subject under the Securities Act, the Exchange Act or other federal or
state law and related to any action or inaction of required of the Holders,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereto) arise out of or are based upon any Violation, in each case to the
extent (and only to the extent) that such Violation occurs by reason of reliance
upon and in conformity with written information furnished by such Holder under
an instrument duly executed by such Holder and stated to be specifically for use
in connection with such registration; and 




<PAGE>   11

                                                                              11


each such Holder will reimburse any legal or other expenses reasonably incurred
by Uniphase or any such director, officer, controlling person, underwriter or
other Holder, or partner, member, officer, director or controlling person of
such other Holder in connection with investigating or defending any such loss,
claim, damage, liability or action if it is judicially determined that there was
such a Violation; provided, however, that the indemnity agreement contained in
this Section 2.10.2 shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of such Holder, which consent shall not be unreasonably withheld;
provided further, that in no event shall any indemnity under this Section 2.10
exceed the net proceeds from the offering received by such Holder.

                           2.10.3.  Promptly after receipt by an indemnified 
party under this Section 2.10 of notice of the commencement of any action
(including any governmental action), such indemnified party will, if a claim in
respect thereof is to be made against any indemnifying party under this Section
2.10, deliver to the indemnifying party a written notice of the commencement
thereof and the indemnifying party shall have the right to participate in, and,
to the extent the indemnifying party so desires, jointly with any other
indemnifying party similarly noticed, to assume the defense thereof with counsel
mutually satisfactory to the parties; provided, however, that an indemnified
party shall have the right to retain its own counsel, with the fees and expenses
to be paid by the indemnifying party, if representation of such indemnified
party by the counsel retained by the indemnifying party would be inappropriate
due to actual or potential differing interests between such indemnified party
and any other party represented by such counsel in such proceeding. The failure
to deliver written notice to the indemnifying party within a reasonable time of
the commencement of any such action, if materially prejudicial to its ability to
defend such action, shall relieve such indemnifying party of any liability to
the indemnified party under this Section 2.10, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section
2.10.

                           2.10.4.  If the indemnification provided for in this 
Section 2.10 is held by a court of competent jurisdiction to be unavailable to
an indemnified party with respect to any losses, claims, damages or liabilities
referred to herein, the indemnifying party, in lieu of indemnifying such
indemnified party thereunder, shall, to the extent permitted by applicable law
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability in such proportion as is appropriate to
reflect the relative fault of the indemnifying party on the one hand and of the
indemnified party on the other in connection with the Violation(s) that resulted
in such loss, claim, damage or liability, as well as any other relevant
equitable considerations. The relative fault of the indemnifying party and of
the indemnified party shall be determined by a court of law by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission to state a material fact relates to information supplied by
the indemnifying party or by the indemnified party and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission; provided, that in no event shall any contribution by
a Holder hereunder

                                                                              12


exceed the proceeds from the offering received by such Holder.

                           2.10.5.  The obligations of Uniphase and the Holders 
under this Section 2.10 shall survive completion of any offering of Registrable
Securities in a registration statement and the termination of this Agreement. No
Indemnifying Party, in the defense of any such claim or litigation, shall,
except with the consent of each Indemnified Party, consent to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such Indemnified Party
of a release from all liability in respect to such claim or litigation. In the
event any offering of Registrable Securities is underwritten, and the
underwriting agreement provides for indemnification and/or contribution by
Uniphase in favor of the Holders offering securities thereunder or of such
Holders in favor of Uniphase, the indemnification and/or contribution
obligations of Uniphase and the Holders hereunder shall in no event exceed the
respective obligations of the parties set forth in such underwriting agreement.

                  2.11.    Assignment of Registration Rights. The rights to 
cause Uniphase to register Registrable Securities pursuant to this Section 2 may
be assigned by Philips to a transferee or assignee of Registrable Securities
that (i) is another Philips Entity, or (iii) acquires Registrable Securities
having a Market Value at the time of assignment of $5,000,000 or more; provided,
however, (A) the transferor shall, within a reasonable time after such transfer,
furnish to Uniphase written notice of the name and address of such transferee or
assignee and the securities with respect to which such registration rights are
being assigned and (B) such transferee shall agree to be subject to all
restrictions set forth in this Agreement.

                  2.12.    Amendment of Registration Rights. Any provision of 
this Section 2 may be amended and the observance thereof may be waived (either
generally or in a particular instance and either retroactively or
prospectively), only with the written consent of Uniphase and the Holders of
more than fifty percent (50%) of the Registrable Securities. Any amendment or
waiver effected in accordance with this Section 2.12 shall be binding upon each
Holder and Uniphase. By acceptance of any benefits under this Section 2, Holders
of Registrable Securities hereby agree to be bound by the provisions hereunder.

                  2.13.    Limitation on Subsequent Registration Rights. After 
the date of this Agreement, Uniphase shall not, without the prior written
consent of the Holders of more than sixty-six and two-thirds percent (66%) of
the then outstanding Registrable Securities, enter into any agreement with any
holder or prospective holder of any securities of Uniphase that would grant such
holder registration rights senior to or on a parity with those granted to the
Holders hereunder, provided that Uniphase may grant subordinate (including
without limitation as to cutback) registration rights to future equity investors
in Uniphase without such consent, provided further that Uniphase may grant pari
passu registration rights ("Pari Passu Registration Rights") to holders or
prospective holders of the Uniphase's securities that are effective after the
Holders shall cease to hold more than five percent (5%) of Uniphase Common Stock
(prior to the Issue Date, giving effect to the hypothetical issuance of Uniphase
Common Stock at the Penalty Conversion Ratio (as defined in the Certificate of
Designation), and provided further, that nothing contained herein shall limit
the ability of Uniphase to register (without participation by 




<PAGE>   13

                                                                              13


the Holders) any shares of Uniphase Common Stock issuable on conversion or
exchange of any convertible note or other derivative security originally issued
by Uniphase after the date hereof, subject to the foregoing. Any right given by
Uniphase to any holder or prospective holder of Uniphase securities in
connection with the registration of securities shall be conditioned such that it
shall be consistent with the provisions hereof and with the rights of the
Holders provided herein.

                  2.14.    "Market Stand-Off" Agreement. If requested by 
Uniphase as the representative of the underwriters of Uniphase Common Stock (or
other securities), neither Uniphase nor any Holder shall sell, assign, pledge,
hypothecate or otherwise transfer or dispose of any shares of Uniphase Common
Stock (or other securities of Uniphase) held by Uniphase or such Holder (other
than those included in an effective registration statement filed prior to such
request), or any right, title or interest therein, for a period specified by the
representative of the underwriters not to exceed one hundred twenty (120) days
following the effective date of a registration statement of Uniphase filed under
the Securities Act, provided that all Holders shall receive the benefit of any
period less than 120 days if such shorter period is offered by the managing
underwriters or underwriter for such offer, to any person required by such
underwriter to be subject to such restriction.

         The obligations described in this Section 2.14 shall not apply to a
registration relating solely to employee benefit plans on Form S-1 or Form S-8
or similar forms that may be promulgated in the future, or a registration
relating solely to a Commission Rule 145 transaction on Form S-4 or similar
forms that may be promulgated in the future. Uniphase may impose stop-transfer
instructions with respect to the shares of Common Stock (or other securities)
subject to the foregoing restriction until the end of said one hundred twenty
(120) day period.

                  2.15.    Rule 144 Reporting. With a view to making available 
to the Holders the benefits of certain rules and regulations of the SEC which
may permit the sale of the Registrable Securities to the public without
registration, Uniphase agrees to use its best efforts to:

                           A.       Make and keep public information available, 
as those terms are understood and defined in SEC Rule 144 or any similar or
analogous rule promulgated under the Securities Act, at all times;

                           B.       Take such action as is necessary to enable 
the Holders to utilize Form S-3 for the sale of Registrable Securities;

                           C.       File with the SEC, in a timely manner, all 
reports and other documents required of Uniphase under the Exchange Act and the
Securities Act; and

                           D.       So long as a Holder owns any Registrable 
Securities, furnish to such Holder forthwith upon request: (i) a written
statement by Uniphase as to its compliance with the reporting requirements of
said Rule 144 of the Securities Act, and of the Exchange Act; (ii) a copy of
each annual and quarterly report of Uniphase; and (iii) such other reports and
documents

                                                                              14


as a Holder may reasonably request in availing itself of any rule or regulation
of the SEC allowing it to sell any such securities without registration.

                  2.16.    Covenant Not to Impair. Uniphase shall not take any 
action or fail to take any action which could reasonably impair the ability of
Uniphase to perform its obligations pursuant to this Section 2.

                  2.17.    No Outstanding Registration Rights. Uniphase hereby
represents and warrants to Philips that, other than the rights granted to
Philips hereunder, no Person has any right to require Uniphase to register any
shares of Uniphase's capital stock held by such Person.


         3.       COVENANTS OF PHILIPS

                  3.1.     Standstill Provisions. For the Standstill Period (as 
defined in Section 3.7 below), Philips shall not (and shall not permit any
Philips Affiliate to), directly or indirectly, acquire from other holders of
Uniphase Common Stock, or other securities convertible into or exchangeable or
exercisable for Uniphase Common Stock, beneficial ownership of any Uniphase
Common Stock, any options, warrants or other securities exercisable for,
convertible into or exchangeable for Uniphase Common Stock, or any other right
to acquire Uniphase Common Stock (except, in any case, by way of stock dividends
or other distributions or offerings made available to holders of any Uniphase
Common Stock or Uniphase Preferred Stock generally), or authorize or make a
tender, exchange or other offer which would result in such an acquisition,
without the written consent of Uniphase; provided that:

                           3.1.1.   Philips (either directly or through a 
Philips Affiliate) shall have the right at any time to effect open market
purchases of Uniphase Common Stock to the extent the aggregate number of shares
of Uniphase Common Stock then held by Philips Entities is below five percent
(5%) of the then total number of outstanding shares of Uniphase Common Stock;
and

                           3.1.2.   This Section 3.1 shall not apply to the 
acquisition by Philips (or a Philips Affiliate) of the Earn-Out Common Stock.

                  3.2.     Notice of Purchases. Philips shall promptly advise 
management of Uniphase as to Philips' (or a Philips Affiliate's) acquisitions of
additional shares of Uniphase Common Stock, or rights thereto, within a
reasonable time period not to exceed thirty (30) days after such acquisition.
All open market purchases of Uniphase Common Stock by Philips (or Philips
Affiliates) shall be made in compliance with applicable laws and regulations.

                  3.3.     No Voting Arrangements. Without Uniphase's prior 
written consent, Philips (or Philips Affiliates) shall not deposit any shares of
Uniphase Common Stock in a voting trust or subject any Uniphase Common Stock to
any arrangement or agreement with respect to the voting of such Uniphase Common
Stock.




<PAGE>   15

                                                                              15


                  3.4.     No Proxies. Without Uniphase's prior written consent,
Philips (or Philips Affiliates) shall not solicit proxies with respect to any
Uniphase Common Stock, nor shall Philips (or Philips Affiliates) become a
"participant" in any "election contest" (as such terms are used in Rule 14a-11
promulgated under the Exchange Act) relating to the election of directors of
Uniphase; provided however, that Philips (or Philips Affiliates) shall not be
deemed to be a "participant" by reason of the membership of Philips' designees
on Uniphase's Board of Directors as provided in Section 4.1 below.

                  3.5.     No Partnerships. Philips (or Philips' Affiliates) 
shall not join any partnership, limited partnership, syndicate or other group,
or otherwise act in concert with any third person for the purpose of acquiring,
holding, voting or disposing of Uniphase Common Stock.

                  3.6.     Voting of Shares Owned by Phillips. During the 
Standstill Period and subject to Section 4 hereof, Philips (directly or through
Philips Affiliates) agrees to vote any shares of Uniphase Common Stock held by
Philips (directly or through Philips Affiliates) for management's nominees to
Uniphase's Board of Directors, and, unless Uniphase otherwise consents in
writing, on all other matters to be voted on by the stockholders in the same
manner and in the same proportion as the votes cast by holders of the majority
of the outstanding shares of Uniphase Common Stock voting with respect to the
applicable matter, except that Philips may vote its Uniphase Common Stock as it
determines as to any proposed amendment to the certificate of incorporation of
Uniphase or any other proposal that Philips determines in good faith materially
and adversely affects the rights, preferences and privileges of the Uniphase
Preferred Stock held by the Philips Entities.

                  3.7.     Standstill Period, Termination of Philips' Covenants.
The covenants set forth in Sections 3.1 through 3.6, inclusive, shall remain in
full force and effect until the first to occur of the expiration of five (5)
years from the date hereof or any of the following events (the "Standstill
Period"):

                           (i)      Uniphase shall be in material breach of its
obligations under the Sale Agreements (other than the Lease or the Site Services
Agreement), and such breach shall not have been cured following five (5)
Business Days' written notice from Philips;

                           (ii)     a third party shall acquire "control" of
Uniphase ("control" being defined as the ability presently or prospectively to
direct the management and policies of Uniphase, directly or indirectly, whether
through ownership of voting securities, by contract or otherwise, and being
presumed any time any such third party shall have greater than 30% of the voting
power to elect directors of Uniphase or the power to elect or designate
directors who fill 20% of the board seats of Uniphase); or

                           (iii)    Uniphase shall in any way facilitate the
acquisition by a third party of "control" of Uniphase (whether by entering into
an agreement for the acquisition of control, recommendation by the Board of
Directors of Uniphase of, or failure to reject, a tender offer by a third party,
issuance of common stock, or otherwise, whether or not "control" is 




<PAGE>   16

                                                                              16


actually acquired by a third party.

                  3.8.     Confidential Information. Uniphase from time to time 
may disclose to the Philips certain technical and nontechnical business
information which Uniphase advises Philips to be confidential. Notwithstanding
any other provision of this Agreement, Philips shall not disclose such
information to third parties (other than information developed or received
independently by Philips) until the earliest of (i) the date upon which such
information becomes public knowledge through no fault of the Philips, (ii) the
date upon which Uniphase discloses such information to a third party on an
unrestricted basis, (iii) the date such information is required to be disclosed
by law or by a court of competent jurisdiction or a regulatory agency, or (iv)
the fifth anniversary of the date of disclosure. In the event that Philips or
any of its representatives is requested or required to disclose confidential
information by law or by a court or regulatory agency, Philips will provide
Uniphase with prompt notice of such request or requirement so that Uniphase may
seek a protective order. Philips further acknowledges and understands that any
information so obtained which may be considered "inside" non-public information
will not be utilized by the Philips in connection with purchases and/or sales of
Uniphase's securities except in compliance with applicable state and federal
securities laws.


        4.        PHILIPS BOARD REPRESENTATION

                  From and after the date hereof and until the later of the
date on which no shares of Uniphase Preferred Stock remain outstanding or the
date on which Philips ceases to hold more than five (5%) of the outstanding
Uniphase Common Stock, Philips shall be entitled to nominate a non-executive
director on the Board of Directors of Uniphase, and Uniphase shall use its
reasonable best efforts (including, without limitation, the solicitation of
proxies) to cause such Philips' nominee to be elected as a member of the Board
of Directors (including creation of a vacancy and filling it with such nominee
at the Closing). Such director shall have equal rights in relation to the other
directors and Uniphase shall use its best effort to have such director
participate as a member of all committees of the Board of Directors other than
the compensation committee.


         5.       MISCELLANEOUS

                  5.1.     Governing Law. This Agreement shall be governed by 
and construed under the laws of the State of New York as applied to agreements
among New York residents entered into and to be performed entirely within New
York.

                  5.2.     Survival. The representations, warranties, covenants,
and agreements made herein shall survive any investigation made by any Holder
and the closing of the transactions contemplated hereby. All statements as to
factual matters contained in any certificate or other instrument delivered by or
on behalf of Uniphase pursuant hereto in connection with the transactions
contemplated hereby shall be deemed to be representations and 




<PAGE>   17

                                                                              17


warranties by Uniphase hereunder solely as of the date of such certificate or
instrument unless otherwise expressly stated herein.

                  5.3.      Successors and Assigns. Except as otherwise 
expressly provided herein, the provisions hereof shall inure to the benefit of,
and be binding upon, the successors, assigns, heirs, executors, and
administrators of the parties hereto and shall inure to the benefit of and be
enforceable by, and to the extent permitted by law be binding upon, each person
who shall be a holder of Registrable Securities from time to time; provided,
however, that prior to the receipt by Uniphase of adequate written notice of the
transfer of any Registrable Securities specifying the full name and address of
the transferee, Uniphase may deem and treat the person listed as the holder of
such shares in its records as the absolute owner and holder of such shares for
all purposes, including the payment of dividends or any redemption price.

                  5.4.     Entire Agreement. This Agreement, the Exhibits and 
Schedules hereto, and the other documents delivered pursuant hereto constitute
the full and entire understanding and agreement between the parties with regard
to the subjects hereof and no party shall be liable or bound to any other in any
manner by any representations, warranties, covenants and agreements except as
specifically set forth herein and therein.

                  5.5.     Amendment and Waiver

                           5.5.1.   Except as otherwise expressly provided, this
Agreement may be amended or modified only upon the written consent of Uniphase
and the holders of more than fifty percent (50%) of the Registrable Securities.

                           5.5.2.   Except as otherwise expressly provided, the 
obligations of Uniphase and the rights of the Holders under this Agreement may
be waived only with the written consent of the holders of more than fifty
percent (50%) of the Registrable Securities.

                  5.6.     Delays or Omissions. It is agreed that no delay or 
omission to exercise any right, power, or remedy accruing to any Holder, upon
any breach, default, or noncompliance of Uniphase under this Agreement shall
impair any such right, power, or remedy, nor shall it be construed to be a
waiver of any such breach, default, or noncompliance, or any acquiescence
therein, or of any similar breach, default, or noncompliance thereafter
occurring. It is further agreed that any waiver, permit, consent, or approval of
any kind or character on any Holder's part of any breach, default, or
noncompliance under the Agreement or any waiver on such Holder's part of any
provisions or conditions of this Agreement must be in writing and shall be
effective only to the extent specifically set forth in such writing. All
remedies, either under this Agreement, by law, or otherwise afforded to Holders,
shall be cumulative and not alternative.

                  5.7.  Incorporation by Reference. Sections 13.3, 13.5, 13.9 
and 13.10 of the Purchase Agreement are hereby incorporated by this reference.

The undersigned officers of Uniphase Corporation, a corporation organized and
existing under the General Corporation Law of the State of Delaware (the
"Corporation"), in accordance with the provisions of Section 103 thereof, DO
HEREBY CERTIFY: 
That, pursuant to the authority conferred upon the Board of Directors of the
Corporation by its Restated Certificate of Incorporation (the "Certificate"),
the said Board of Directors, at a duly called meeting held on April 8, 1998, at
which a quorum was present and acted throughout, adopted the following
resolutions, which resolutions remain in full force and effect on the date
hereof creating a series of 100,000 shares of Preferred Stock having a par value
of $.001 per share, designated as Series A Preferred Stock (the "Series A
Preferred Stock") out of the class of 1,000,000 shares of preferred stock, par
value of $.001 per share (the "Preferred Stock") of the Corporation:

RESOLVED, that pursuant to the authority vested in the Board of Directors in
accordance with the provisions of the Certificate, the Board of Directors does
hereby create, authorize and provide for 100,000 shares of its authorized
Preferred Stock to be designated and issued as the Series A Preferred Stock;

RESOLVED, that pursuant to the authority of Section 151(a) of the Delaware
General Corporate Law, certain matters related to the voting powers,
designations, preferences, rights and qualifications, limitations or
restrictions of the Series A Preferred Stock are dependent upon facts
ascertainable outside the Certificate or these resolutions (the "External
Facts");

RESOLVED, that all External Facts shall be determined and ascertained only in
reference to and in accordance with the terms of that certain Series A Preferred
Stock Conversion and Redemption Agreement, dated as of May 18, 1998, exclusive
of any amendments or modifications thereafter (the "Series A Preferred Stock
Agreement"), between the Corporation and Koninklijke Philips Electronics N.V., a
company established under the law of the Netherlands ("Philips"), a copy of
which is available, upon request, to any holder of the Series A Preferred Stock
at the Corporation's principal offices;

          Preferred Stock which has not been redeemed pursuant to Section 4
          below or converted pursuant to Section 2(b) below shall automatically
          be converted into that number of shares of Common Stock equal to the
          Per Share Earn-Out Amount divided by the average last reported sale
          price on the NASDAQ National Market (as published in the Wall Street
          Journal, Eastern Edition) of one share of Common Stock (as then
          constituted) over the twenty (20) trading days ending immediately
          prior to the Issue Date.

     (b)  Right to Convert on Occurrence of Redemption Event. All shares of
          Series A Preferred Stock which has not been redeemed pursuant to

          Preferred Stock, into shares of Common Stock in accordance with this
          Section 2(b) in the event a Redemption Event (as defined in the Series
          A Preferred Stock Agreement) occurs on or before June 30, 2002. Such
          Conversion Rights shall be exercisable by a majority of the holders of
          Series A Preferred Stock on written notice to the Corporation for a
          period of ninety (90) days following the date Philips (as defined in
          Section 7 below) determines that a Redemption Event has occurred (the
          "First Election Period") or, if such Conversion Right is not exercised
          during the First Election Period, for a period of thirty (30) days
          preceding July 1, 2002 (the "Second Election Period"). The number of
          shares of Common Stock issuable upon conversion of a share of Series A
          Preferred Stock pursuant to this Section 2(b) shall be equal to the
          Redemption Price divided by the average last reported sale price on
          the NASDAQ National Market (as published in the Wall Street

                                                                               3


          Journal, Eastern Edition) of one share of Common Stock (as then
          constituted) over the twenty (20) trading days ending immediately
          prior to commencement of the First Election Period (if such Conversion
          Rights are exercised pursuant to this Section 2(b) during the First
          Election Period) or the Issue Date (if such Conversion Rights are
          exercised pursuant to this Section 2(b) during the Second Election
          Period).

     (c)  Mechanics of Conversion. In the event of an automatic conversion of
          the Series A Preferred Stock pursuant to Section 2(a) hereof or an
          election by the holders of at least a majority of the then outstanding
          shares of Series A Preferred Stock to convert all of the Series A
          Preferred Stock pursuant to Section 2(b) above, the outstanding shares
          of Series A Preferred Stock shall then be converted automatically
          without any further action by the holders of such shares into shares
          of Common Stock and whether or not the certificates representing such
          shares are surrendered to the Corporation or its transfer agent;
          provided that the Corporation shall not be obligated to issue
          certificates evidencing the shares of Common Stock issuable upon such
          automatic conversion unless and until the certificates evidencing such
          shares of Series A Preferred Stock are either delivered to the
          Corporation or its transfer agent as provided above, or the holder
          notifies the Corporation or its transfer agent that such certificates
          have been lost, stolen or destroyed and executes an agreement
          satisfactory to the Corporation to indemnify the Corporation from any
          loss incurred by it in connection with such certificates. The
          Corporation shall, as soon as practicable after such delivery, or
          after such agreement and indemnification, issue and deliver to such
          holder of Series A Preferred Stock, a certificate or certificates for
          the number of shares of Common Stock to which he or she shall be
          entitled as aforesaid. Such conversion shall be deemed to have been
          made immediately prior to the occurrence of the event leading to such
          automatic conversion or the election of the holders, as the case may
          be, and the person or persons entitled to receive the shares of Common
          Stock issuable upon such conversion shall be treated for all purposes
          as the record holder or holders of such shares of Common Stock on such
          dates.

     (d)  Reclassifications; Mergers or Consolidations. In the case of any
          capital reorganization or any reclassification of the stock of the
          Corporation (other than as a result of a stock dividend or
          subdivision, split-up or combination of shares) or the consolidation
          or merger of the Corporation with or into another person or of the
          sale or other disposition of all or substantially all the properties
          and assets of the

                                                                               4


          Corporation at any time after the date thereof, the shares of the
          Series A Preferred Stock shall, after such reorganization,
          reclassification, consolidation, merger, sale or other disposition, be
          convertible into the kind and number of shares of stock, other
          securities, cash or other property to which such holder would have
          been entitled if immediately prior to such reorganization,
          reclassification, consolidation, merger, sale or other disposition
          such holders had converted such shares of the Series A Preferred Stock
          into Common Stock. The provisions of this Section 2(d) shall (i)
          similarly apply to successive reorganizations, reclassifications,
          consolidations, mergers, sales or other dispositions, and (ii) be
          subject to the rights of the holders of the Series A Preferred Stock
          pursuant to Section 2(b) above and Section 4 below following the
          occurrence of a Redemption Event.

     (e)  Fractional Shares. In lieu of any fractional shares to which the
          holder of Series A Preferred Stock would otherwise be entitled upon
          conversion, the Corporation shall pay cash equal to such fraction
          multiplied by the value of one share of Common Stock as determined in
          accordance with Section 2(a) or Section 2(b) hereof as applicable. The
          number of whole shares issuable to each holder upon such conversion
          shall be determined on the basis of the number of shares of Common
          Stock issuable upon conversion of the total number of shares of Series
          A Preferred Stock held by such holder at the time of conversion
          pursuant to Section 2 hereof.

     (f)  No Impairment. The Corporation will not through any reorganization,
          recapitalization, transfer of assets, consolidation, merger,
          dissolution, issue or sale of securities or any other voluntary
          action, avoid or seek to avoid the observance of performance of any of
          the terms to be observed or performed hereunder by the Corporation,
          but will at all times in good faith assist in the carrying out of all
          the provisions of this Section 2 and in the taking of all such action
          as may be necessary or appropriate in order to protect the Conversion
          Rights of the holders of Series A Preferred Stock against impairment.

     (g)  Reservation of Stock Issuable Upon Conversion. The Corporation shall
          at all times reserve and keep available out of its authorized but
          unissued shares of Common Stock, solely for the purpose of effecting
          the conversion of the shares of Series A Preferred Stock, such number
          of shares of Common Stock as shall from time to time be sufficient to
          effect the conversion of all outstanding shares of Series A Preferred
          Stock. If at any time the number of authorized but unissued shares of
          Common 




<PAGE>   5

                                                                               5


          Stock shall not be sufficient to effect the conversion of all
          then-outstanding shares of Series A Preferred Stock, the Corporation
          will take such corporate action as may, in the opinion of its counsel,
          be necessary to increase its authorized but unissued shares of Common
          Stock to such number of shares as shall be sufficient for such
          purpose.

3.   Voting Rights. The Series A Preferred Stock shall have no voting rights
     except as required by law and except that approval of Philips, as long as
     Philips is a holder of shares of Series A Preferred Stock, or more than
     fifty percent (50%) of the outstanding shares of Series A Preferred Stock,
     in the event that Philips is no longer such a holder, shall be required as
     to any amendment to the Certificate or this Certificate of Designation
     that: (i) changes or alters the rights of the Series A Preferred Stock so
     as to adversely affect the rights and privileges of the holders of the
     Series A Preferred Stock, or (ii) increases the number of authorized shares
     of Series A Preferred Stock.

4.   Redemption.

     (a)  Redemption of Series A Preferred Stock. In the event a Redemption
          Event shall occur on or before June 30, 2002, the Corporation shall,
          at the request of the holders of at least a majority of the then
          outstanding shares of Series A Preferred Stock, redeem all outstanding
          shares of Series A Preferred Stock at the Redemption Price; provided,
          that, if the Redemption Event is a Company Sale, such Redemption Event
          shall not give rise to a redemption of the Series A Preferred Stock
          pursuant to this Section 4. Holders of Series A Preferred Stock
          requesting redemption hereunder shall promptly notify the Corporation.
          Such notice (the "Redemption Notice") shall specify the date of the
          requested redemption (the "Redemption Date") and shall be given, if at
          all, during either the First Election Period or the Second Election
          Period, as the case may be. The Corporation shall reply to the
          Redemption Notice within fifteen (15) days by notifying the holder or
          holders of Series A Preferred Stock requesting redemption hereunder of
          the number of shares which the Corporation may lawfully redeem
          consistent with the requirements of Section 160 of the Delaware
          General Corporation Law on the date specified for redemption.

     (b)  Redemption Payments. For each share of Series A Preferred Stock which
          is to be redeemed hereunder, the Corporation shall be obligated on the
          Redemption Date to pay to the holder thereof (upon surrender by such
          holder at the Corporation's principal office of the certificate
          representing such share) an amount in immediately 




<PAGE>   6

                                                                               6


          available funds equal to the Redemption Price. If the funds of the
          Corporation legally available for redemption of shares of Series A
          Preferred Stock on the Redemption Date consistent with the
          requirements of Section 160 of the Delaware General Corporation Law
          are insufficient to redeem the total number of shares of Series A
          Preferred Stock to be redeemed on such date, those funds which are
          legally available under Section 160 of the Delaware General
          Corporation Law shall be used to redeem the maximum possible number of
          shares of Preferred Stock pro rata among the holders of Series A
          Preferred Stock to be redeemed based upon the aggregate number of
          shares of Series A Preferred Stock held by each such holder in
          accordance with subsection (c) below. At any time thereafter when
          additional funds of the Corporation are legally available under
          Section 160 of the Delaware General Corporation Law for the redemption
          of shares of Series A Preferred Stock, such funds shall immediately be
          used to redeem the balance of the shares of Series A Preferred Stock
          which the Corporation has become obligated to redeem on the Redemption
          Date but which it has not so redeemed.

     (c)  Determination of the Number of Each Holder's Shares to be Redeemed.
          The number of shares of Series A Preferred Stock to be redeemed from
          each holder thereof in redemptions of fewer than all of the
          outstanding shares of Series A Preferred Stock hereunder shall be the
          number of shares determined by multiplying the total number of Series
          A Preferred Stock, to be redeemed by a fraction, the numerator of
          which shall be the total number of shares of Series A Preferred Stock
          then held by such holder and the denominator of which shall be the
          total number of shares of Series A Preferred Stock then outstanding.
          In case fewer than the total number of shares represented by any
          certificate are redeemed, a new certificate representing the number of
          unredeemed shares shall be issued to the holder thereof without cost
          to such holder within five business days after surrender of the
          certificate representing the redeemed shares.

5.   Ranking. The shares of Series A Preferred Stock shall rank junior to all
     other series of the Preferred Stock and to any other class of Preferred
     Stock that hereafter may be issued by the Corporation as to the payment of
     dividends and the distribution of assets upon liquidation, unless the terms
     of any such series or class shall provide otherwise.

6.   Reacquired Shares. Any shares of Series A Preferred Stock redeemed,
     converted or otherwise acquired by the Corporation in any manner whatsoever
     shall be retired and 




<PAGE>   7

                                                                               7


     cancelled promptly after the acquisition thereof. All such shares shall,
     upon their cancellation, become authorized but unissued shares (or
     fractions of shares) of Preferred Stock and may be reissued as part of a
     new series of Preferred Stock to be created by resolution or resolutions of
     the Board of Directors, subject to the conditions and restrictions on
     issuance set forth herein.

7.   Common Stock Definition. As used in this resolution, the term "Common
     Stock" shall mean the class of stock designated as the common stock, par
     value $.001 per share, of the Corporation at the date hereof or any other
     class of stock resulting from successive changes or reclassification of the
     common stock.


IN WITNESS WHEREOF, Uniphase Corporation has caused this Certificate to be
signed by its President and its Assistant Secretary this 29th day of May, 1998.

R E C I T A L S

1.   Philips, Uniphase, Philips Optoelectronics B.V., a company established

     four-year period that is to commence on July 1, 1998 upon the terms
     provided herein and in the Certificate of Designation.

     with past practices for which no charge (other than transport and handling
     charges) is made to the customer during the relevant period.

     "Company Sale" shall mean (i) a sale of all or substantially all of the
     assets of Uniphase; (ii) a merger in which Uniphase shall not be the

     Uniphase, directly or indirectly, whether through ownership of voting
     securities, by contract or otherwise, and being presumed any time any such
     third party shall own beneficially securities of Uniphase having greater

     determining the number of shares of Uniphase Common Stock, if any, issuable

     Holders to redeem the Uniphase Preferred Stock.

     "Earn-Out Period" shall mean the four (4) successive twelve (12) month
     periods commencing July 1 and ending June 30 of the next calendar year, of
     which the first twelve (12) month period is to commence July 1, 1998.

     "Percentage Performance" for any Earn-Out Period Year or the Earn-Out
     Period, as the case may be, shall mean the percentage amount determined by
     dividing the number of Target Unit Shipments by the number of Actual Unit
     Shipments for that same period; provided, that, in the event that the
     Percentage Performance for any Earn-Out Period Year is less than forty-five
     percent (45%), the Percentage Performance for the subsequent Earn-Out
     Period Year shall be reduced by the percentage amount by which the
     Percentage Performance for such prior Earn-Out Period Year was less than
     forty-five percent (45%) as determined on the basis of Actual Unit
     Shipments for that year and after giving effect in that year to the
     foregoing adjustment on the basis of Percentage Performance for the prior
     Earn-Out Period Year; provided, that to the extent such percentage amount
     is applied to reduce Percentage Performance for a subsequent Earn-Out Year
     that is excess of one hundred percent (100%), that portion of such
     percentage amount that is applied against Percentage Performance is excess
     of one hundred percent (100%) shall be divided by 1.82. For purposes of
     example, Percentage Performance shall be calculated in a manner

     Earn-Out Period Year in which the Percentage Performance was equal to or
     greater than forty-five percent (45%) but not in excess of one hundred
     percent (100%), an amount equal to the quotient obtained by dividing (A)
     the Percentage Performance for the Earn-Out Period Year less forty-five
     percent (45%) by (B) fifty-five percent (55%); and (iii) for any Earn-Out
     Period year in which the Percentage Performance is in excess of one hundred
     percent (100%), an amount equal to the quotient obtained by dividing the
     Percentage Performance for that Earn-Out Plan Year by one hundred percent
     (100%).

     the Uniphase Preferred Stock pursuant to Section 4(a) of the Certificate of
     Designation.

     "Redemption Event" shall mean and be limited to: (i) a termination or
     discontinuance of the Activity by Uniphase which is not the result of a
     material adverse change in the market for WDM Lasers and/or
     electro-absorption modulators or general economic conditions; (ii) a sale
     or transfer of Opto or the Activity or all or substantially all of the
     assets of the Activity in a single transaction or series of transactions,
     without Philips' prior written consent; (iii) a Company Sale; or (iv) a
     material breach by Uniphase of its obligations pursuant to Section 5.2

     Activity not achieving the Target Unit Shipments; and (B) Philips shall
     have given notice to Uniphase of such breach and Uniphase shall not have
     cured such breach in all material respects within thirty (30) days
     following such notice.

     "Redemption Price" shall have the meaning set forth in Section 4.2 below.

     "Target Unit Shipments" shall mean those projected unit quantities of WDM
     Lasers to be shipped during each Earn-Out Period Year and the Earn-Out
     Period as set forth in Section 3.1 below. For purposes of determining the
     aggregate number of Target Unit Shipments for any period, a WDM Laser that
     includes an integrated electro-absorption modulator element shall be
     counted as two (2) shipments.

     "WDM Laser" shall mean a fiber-pigtailed semiconductor laser with single
     frequency emission on a grid, anchor at 193.1 THZ, and with spacing of nx50
     GhZ (n = 1, 2 ...) spanning the extended EDFA (Erbium Doped Fiber
     Amplifier) window. WDM Lasers can

                                                                               5

     be either stand-alone or included in modules and either operated as CW
     (continuous wave), directly modulated or be a DFB laser chip with-on the
     same substrate - an integrated EA (electro absorption) modulator element.

SECTION 2.        No Transfer of Uniphase Preferred Stock

During the term of this Agreement, Philips shall not be permitted or authorized
to transfer, sell or assign any shares of Uniphase Preferred Stock except to
Philips Affiliates. To the extent a Philips Affiliate shall become a Preferred
Holder and thereafter cease to be a Philips Affiliate prior to the termination
of this Agreement, Philips agrees to cause any such Preferred Holder to transfer
all shares of Uniphase Preferred Stock held by it to Philips or another Philips'
Affiliate prior to the date such entity ceases to be a Philips Affiliate.

SECTION 3.        Calculation of Per Share Earn-Out Amount

3.1. Uniphase and Philips agree that the following amounts of shipments of WDM
     Lasers shall constitute the Target Unit Shipments for each of the four (4)
     Earn-Out Period Years and for the Earn-Out Period:

                                 YEAR 1    YEAR 2    YEAR 3    YEAR 4    TOTAL
                                 ------    ------    ------    ------    -----
Target Unit Shipments ........    ****      ****      ****      ****      ****

     The foregoing amounts in the first four columns constitute the Target
     Shipment Units for each Earn-Out Period Year and are not cumulative between
     such years.

3.2. For each Earn-Out Period Year that is completed, the Accrued Contingent
     Payment for that Earn-Out Period Year shall be an amount equal to (i) the
     product of: (A) NLG 50 million; and (B) the Performance Factor; plus (ii)
     interest on such amount at the rate of 15.2% from July 1, 1998 until the
     Issue Date, compounded annually. Upon completion of the Earn-Out Period and
     in any event not later than June 30, 2002 and subject to Section 3.3 below,
     the Per Share Earn-Out Amount shall be determined in an amount equal to the
     quotient obtained by dividing the sum of the Accrued Contingent Payments
     for each of the four (4) Earn-Out Period Years that have been completed by
     100,000 (as appropriately adjusted for any stock splits or combinations
     that shall occur after the date hereof and prior to the Issue Date with
     respect to the Uniphase Preferred Stock). The Per Share Earn-Out Amount
     shall

                                                                               6

     apply to determine the number of shares of Uniphase Common Stock, if any,
     into which a share of Uniphase Preferred Stock shall be convertible in
     accordance with Section 2(a) of the Certificate of Designation.

3.3. Notwithstanding any term or condition of this Agreement, the Per Share
     Earn-Out Amount shall: (i) be zero (0) if the Percentage Performance for
     the Earn-Out Period is less than fifty-four point five percent (54.5%); and
     (ii) in no event exceed NLG 4,579.13. In the event that the Aggregate
     Contingent Payment as of the Issue Date is zero (0) or alternatively the
     Percentage Performance for the Earn-Out Period is less than fifty-four
     point five percent (54.5%), the Uniphase Preferred Stock shall be deemed
     cancelled and retired as of July 31, 2002 without issuance of any Uniphase
     Common Stock or payment of further consideration by Uniphase.

SECTION 4.        Occurrence of Redemption Event

4.1. In the event a Redemption Event shall occur on or before June 30, 2002, the
     Preferred Holders shall, subject to and in accordance with the terms of the
     Certificate of Designation, have the right to elect to redeem all (but only
     all) of the Uniphase Preferred Stock at the Redemption Price or to convert
     all (but only all) of the Uniphase Preferred Stock at the Redemption Price;
     provided, that, if the Redemption Event is a Company Sale, such Redemption
     Event shall only give rise to a right on the part of the Preferred Holders
     to convert their shares of Uniphase Preferred Stock at the Redemption Price
     as provided in Section 2(b) of the Certificate of Designation.

4.2. The per share redemption price (the "Redemption Price") as of any
     Redemption Date shall be equal to the quotient obtained by dividing: (i)
     the sum of: (A) for any Earn-Out Period Year that is then completed, the
     Accrued Contingent Payment for that year; and (B) for each Earn-Out Period
     that is not then completed, the greater of: (1) the Accrued Contingent
     Payment that would accrue for that year based on Percentage Performance of
     one hundred percent (100%); or (2) the Accrued Contingent Payment that
     would accrue for that year based on the average Percentage Performance for
     each Earn-Out Period Year that is then completed; plus (C) interest on the
     sum of clause (A) and (B) at the rate of 15.2% from July 1, 1998 to the
     Redemption Date (or for purposes of Section 2(b) of the Certificate of
     Designation, the Issue Date); by (ii) 100,000 (as appropriately adjusted
     for any stock splits or combinations that occur after the date hereof and
     prior to the Issue Date with respect to Uniphase Preferred Stock).

                                                                               7

SECTION 5.        Earn-Out Matters

5.1. Uniphase acknowledges that the value of the consideration to be received by
     Philips for the Activity is in significant part dependent on operation of
     the Activity after the date hereof. Accordingly, Uniphase agrees that it
     shall operate and maintain the Activity in the ordinary course consistent
     with Uniphase's operation of its other businesses, subject to Uniphase's
     primary goal of maximizing value of Uniphase Common Stock for the benefit
     of its stockholders, operate the Activity with reasonable regard to
     Philips' interest to earn the maximum Earn-Out (as set out in Clause 3.3
     (ii)). Without in any way limiting the obligations imposed on Uniphase by
     the immediately preceding sentence, for the period from the date hereof
     through the Issue Date, Uniphase shall, and shall cause the Uniphase
     Parties to, (i) maintain its corporate existence in good standing and
     qualify and remain qualified to do business in each jurisdiction in which
     it does business at the date hereof, (ii) in the absence of any material
     adverse change in the market for WDM Lasers or general economic conditions,
     continue the business of shipment of WDM Lasers, (iii) use its reasonable
     commercial efforts to preserve, renew and keep in full force and effect all
     its franchises and licenses necessary or desirable in the normal conduct of
     its business, (iv) use its reasonable commercial efforts to comply with all
     applicable laws, orders, rules and regulations of all governmental
     authorities required for the continued conduct of its business as conducted
     at the date hereof, (v) keep proper books of record and account, in
     accordance with Uniphase's accounting practices, for the purpose of
     verifying the shipment of WDM Lasers with respect to the Earn-Out during
     the Earn-Out Period; (vi) use reasonable commercial efforts to maintain and
     preserve its business organization, retain the services of its present
     officers and employees and maintain its relationships with its suppliers
     and customers and (vii) subject to Philips' obligation to comply with
     relevant insider trading rules under applicable U.S. Securities laws,
     notify Philips promptly of any adverse change or prospective adverse change
     in its consolidated business, properties, financial condition or
     operations, present or prospective. Uniphase shall not, and shall cause any
     Uniphase Affiliate not to, cause or suffer to occur any other event or
     condition that may affect Uniphase's ability to satisfy its obligations set
     forth in the immediately preceding sentence. Breach of the matters set
     forth in this Section 5.1, to the extent such breach causes the amount of
     the Earn-Out to be materially and adversely affected, shall give Philips
     the right to monetary damages in addition to the rights of Philips upon the
     occurrence of a Redemption Event.

5.2. In the absence of any material adverse change in the market for WDM Lasers
     or in general

<PAGE>   8
                                                                               8

     economic conditions and any material deviations in the Actual Unit
     Shipments from the Target Unit Shipments in during any portion of the
     Earn-Out Period, Uniphase shall provide working capital and capital
     expenditure funding to the Activity (or otherwise maintain within the
     Activity cash flow from the operations of the Activity) in such amounts as
     Uniphase, in the good faith exercise of its business judgement, determines
     is reasonably sufficient to achieve the Target Unit Shipments. Such funding
     shall be provided or otherwise made available to the Activity at such times
     as Uniphase shall determine in exercising such business judgment and, in
     the case of capital expenditure, may be provided in the form of purchase,
     lease or any form of leveraged financing as Uniphase shall determine. In
     the event Philips determines that Uniphase is not providing or otherwise
     making available sufficient working capital and capital expenditure funding
     to the Activity at any time during the Earn-Out Period, Philips shall give
     Uniphase notice of such failure, and Philips and Uniphase agree to
     negotiate in good faith as to the appropriate level of funding for the
     Activity for a period of not less than thirty (30) days following the
     notification from Philips. In the event that Uniphase fails in any material
     respect to provide the needed funding that is agreed by Philips and
     Uniphase through such negotiations, Uniphase shall be deemed in breach of
     its obligations pursuant to this Section 5.2. In all other cases, Uniphase
     shall only be deemed to be in breach of this Section 5.2 if it is
     determined that Uniphase has not acted in good faith in determining the
     level of funding for the Activity or in its negotiations with Philips as
     provided in this Section 5.2 as to the funding levels.

5.3. Within fifteen (15) days after the end of each of Uniphase's first three
     fiscal quarters during an Earn-Out Period Year and within forty-five (45)
     days after the end of each Earn-Out Period Year, Uniphase shall deliver to
     Philips a statement setting forth the number of WDM Lasers shipped in such
     quarter and for the Earn-Out Period Year to date, together with a
     reasonably detailed summary of shipments by product type, customer and
     shipment date (the "Quarterly Statement"). Philips shall be entitled to
     take such steps as it deems reasonably necessary to verify the contents of
     each Quarterly Statement (including without limitation the right to contact
     Uniphase customers) and Uniphase shall cooperate, and shall cause its
     auditors to cooperate, in enabling Philips to do so. Uniphase shall cause
     to be delivered certificates of Uniphase's chief financial officer,
     certifying to the accuracy of the information set forth in each of the four
     Quarterly Statements together with the Quarterly Statement for the fourth
     fiscal quarter of each Earn-Out Period Year, which shall include Actual
     Unit Shipments for the entire preceding Earn-Out Period Year and be
     certified by Uniphase's independent auditors.

                                                                               9

SECTION 6.        Agreement Binding on All Preferred Holders

6.1. Subject to Section 2, Philips and each Preferred Holder agrees, as a
     condition precedent to the assignment, sale or transfer of any shares of
     Uniphase Preferred Stock prior to the Issue Date to require the proposed
     assignee, purchaser or transferee other than the Company or another
     Preferred Holder to become bound by this Agreement.

6.2. Prior to the Issue Date, each certificate for shares of Preferred Stock
     issued to or held by Preferred Holders shall bear the following legend:

          "THE RATE AT WHICH THE SHARES OF SERIES A PREFERRED STOCK REPRESENTED
          BY THIS CERTIFICATE ARE CONVERTIBLE INTO COMMON STOCK IS SUBJECT TO AN
          AGREEMENT BETWEEN THE CORPORATION AND THE HOLDERS OF SERIES A
          PREFERRED STOCK, A COPY OF WHICH AGREEMENT IS AVAILABLE UPON REQUEST
          AT THE PRINCIPAL OFFICES OF THE CORPORATION."

SECTION 7.        Miscellaneous

7.1. This Agreement shall remain in full force and effect until the Issue Date
     and shall terminate after the conversion and/or redemption of all Uniphase
     Preferred Stock.

7.2. A Majority of the Preferred Holders is hereby authorized to take any action
     which they deem appropriate or necessary to carry out the provisions of
     this Agreement. Each Preferred Holder hereby agrees to be bound by the
     actions of a Majority of the Preferred Holders for the purposes of this
     Agreement, and each Preferred Holder further agrees to cooperate with the
     Majority of the Preferred Holders with respect to such actions.

7.3. Within sixty (60) days of receipt of the certificates of Uniphase's chief
     financial officer and auditors in each Earn-Out Period Year, Philips shall
     be entitled to give notice to Uniphase of its objections to any of the
     Quarterly Statements delivered to Philips in that Earn-Out Period Year,
     and, at Philips' option, at the end of the Earn-Out Period, Philips shall
     be entitled to give notice to Uniphase of its objections to any of the
     Quarterly Statements delivered to Philips in that Earn-Out Period. If
     Philips gives any such notice of objection, then the issues in dispute will
     be promptly submitted to Price Waterhouse or such other certified public
     accountants as may be agreed (the "Accountants"), for resolution. If issues

<PAGE>   10
                                                                              10

     in dispute are submitted to the Accountants for resolution, (i) each party
     shall furnish to the Accountants such work papers and other documents and
     information relating to the disputed issues as the Accountants may request,
     and will be afforded the opportunity to present to the Accountants any
     material relating to the determination and to discuss the determination
     with the Accountants; (ii) the determination by the Accountants, as set
     forth in a notice delivered to both parties by the Accountants, will be
     binding and conclusive on the parties; and (iii) Philips and Uniphase shall
     each bear fifty percent (50%) of the fees of the Accountants for such
     determination. Within five (5) business days following final determination
     of the issues in dispute, Philips and Uniphase shall take such action as is
     necessary to ensure that the rate at which the Uniphase Preferred Stock
     held by Philips or Philips Affiliates is convertible (or the number of
     shares of common stock held by Philips) reflects the resolution of the
     issues in dispute (including without limitation adjustment of the
     conversion rate retroactively to the Issue Date, the issuance to Philips of
     additional shares of Uniphase Common Stock and the return by Philips of
     shares of Uniphase Common Stock).

7.4. Sections 13.2, 13.3, 13.4, 13.5, 13.9 and 13.10 of the Purchase Agreement
     are hereby incorporated by this reference.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the
day and year hereinabove first written.

<PAGE>   5

4.4.    The payment obligation with respect to the buildings WBC and WBD starts
        on the date the buildings are available for occupation.

4.5.    The rent shall be adjusted in accordance with Articles 4.1 - 4.4 of the

4.7.    If required to do so by the Lessee, the Lessor will with respect to the

        Lessee as well as site services referred to in the site service
        agreement attached in annex 5, on comparable terms and conditions of

4.8.    For every payment period shall be 1 (one) calendar month. Payments are
        due on the first day of the month.

ARTICLE 5 - VALUE-ADDED (VAT)

5.1.    All sums specified in this agreement shall be exclusive of VAT.

5.2.    The parties agree that the Lessor shall charge the Lessee VAT on the
        rent.

5.3.    The Lessee herewith grants the Lessor and its legal successor(s) an

        Lessor within 14 days of receiving it from the Lessor.


<PAGE>   6

5.4.    Lessee declares that it is using the leased premises for purposes which
        allow it to recover at least 90% of the VAT calculated on the rent
        installments. In the event this is no longer so, Lessee will report this
        in writing to the Lessor.

5.5.    In the event that the tax authorities, notwithstanding a properly filed
        option request, do not allow a VAT taxed rent, or in the event approval
        of taxed rent be withdrawn, Lessee shall compensate Lessor for its
        damage as a result of the fact that part of the VAT that the Lessor
        deducted when constructing the leased premises shall be reimbursed to
        the tax authorities. The compensation to be paid by Lessee will occur by
        way of increase of the rent, this being at most the amount of VAT that
        should have been due if taxed rent was allowed.

5.6     Notwithstanding the foregoing, the Lessor is entitled to an additional
        increase of the rent in accordance with the damage resulting from the
        fact that it cannot recover its VAT on maintenance costs. This only
        refers to the buildings WAD and WAM.

        premises. The Lessor may give its consent conditionally, but may not
        withhold its consent on unreasonable grounds. All adjustments will
        remain the Lessee's property and Lessee will be entitled to remove these
        adjustments unless the parties agree otherwise. They may agree the

        the competent authorities approve of the Lessee performing its business
        subject to Lessor's Environmental Control Act Permit.

6.5     The Lessor undertakes to assist the Lessee with further developing the
        Internal Environmental report and to assist the Lessee with filing the
        request for an Environmental Control Act Permit, should this be
        necessary, without being entitled to recover the costs thereof from the
        Lessee.
