ITEM 17.  UNDERTAKINGS
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act, and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question of
whether such indemnification by it is against public policy as expressed in
the Securities Act and will be governed by the final adjudication of such
issue.
 
  The undersigned Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of Prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4), or
  497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of Prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.
 
    (3) For the purpose of determining liability under the Securities Act,
  each filing of the Registrant's annual report pursuant to Section 13(a) or
  Section 15(d) of the Securities Exchange Act of 1934 (and, where
  applicable, each filing of an employee benefit plan's annual report
  pursuant to Section 15(d) of the Exchange Act) that is incorporated by
  reference in the Registration Statement shall be deemed to be a new
  registration statement relating to the securities offered therein, and the
  offering of such securities at that time shall be deemed to be the initial
  bona fide offering thereof.

     ------------------------------------

     4.1   The Vendors represent, warrant and undertake to the Purchaser that
           each of the Warranties is true and accurate in all respects and not
           misleading as a result of any omission or otherwise.

     4.2   ITS, to the best of its knowledge but not having made any enquiry
           other than of the Vendors and the Company and save as provided in the
           Sale Documents represents warrants and undertakes to the Purchaser
           that each of the Warranties set out in Clause 8 of Schedule 3 Part IV
           of this Agreement is true and accurate 

                                      10

<PAGE>
 
           in all material respects and not misleading as a result of any 
           omission or otherwise.

     4.3   Immediately before the time of Completion, both the Vendors and ITS
           shall be deemed to repeat the Warranties given pursuant to Clauses
           4.1 and 4.2 (as the case may be) by reference to the facts then
           subsisting. For this purpose any express or implied reference in a
           Warranty to the date of this Agreement is to be construed as a
           reference to the date of Completion.

     4.4   The Vendors and ITS respectively acknowledge that the Purchaser is
           entering into this agreement in reliance upon the Warranties and that
           they form the basis of this agreement.

     4.5   The Warranties are qualified only by and to the extent that matters
           are fairly disclosed in the Disclosure Letter in respect of them.
 
     4.6   The Vendors and ITS respectively agree with the Purchaser to waive
           any of their respective rights in respect of any inaccuracy or
           omission in or from any information or advice supplied or given by
           the Company and any officers or employees (save in their capacity as
           Vendors) of the Company in connection with the Warranties, the Tax
           Covenant or the Disclosure Letter or other Sale Documents, and agrees
           that any such advice or information does not constitute a
           representation and that no warranty or guarantee has been given in
           respect of its accuracy.

     4.7   The rights and remedies of the Purchaser or any amount recoverable
           shall not be affected by completion of this agreement nor by any
           investigation made by or on behalf of the Purchaser into the affairs
           of the Company nor by any other information relating to it known
           (actually or constructively) to the Purchaser.

     4.8   Each of the Warranties is separate and independent and (except as
           otherwise expressly provided) is not limited or restricted by
           reference to or inference from the terms of any other provision of
           this agreement or the other Sale Documents or by the giving of any
           time or other indulgence by the Purchaser to any person but shall
           only be affected by a specific waiver or release by the Purchaser in
           writing and any such waiver or release shall be specific to the
           matter to which it relates and not prejudice or affect any other
           rights of the Purchaser.

     4.9   Where any of the Warranties is qualified by an expression such as "so
           far as ITS is aware" or "so far as the Vendors are aware" as the case
           may be, or "to the best of the knowledge information and belief of
           ITS" or to the best of the knowledge information and belief of the
           Vendors as the case may be, or any similar expression, it shall be
           deemed (unless expressly otherwise stated) to include an additional
           statement that it has been made after due diligent and careful
           enquiry.

     4.10  Without restricting the rights of the Purchaser or the ability of the
           Purchaser to claim damages on any basis available to it, if any of
           the Warranties is broken, untrue or misleading the Vendors or ITS as
           the case may be in relation to the Warranties given by them shall on
           demand pay to the Purchaser:

          4.10.1  the amount necessary to put the Company, at the date of the
                  demand, into the position which would have existed had the
                  Warranty not been broken, untrue or misleading;

          4.10.2  (without prejudice to sub-clause 4.9.1) in respect of any
                  breach of the Warranties relating to the Property, an amount
                  equal to the difference between the value of the Property had
                  those warranties been true or not broken and the actual value
                  of the Property at the date of the demand together with the
                  amount of any other loss occasioned by such breach; and

          4.10.3  all costs and expenses incurred by the Purchaser and the
                  Company as a result of the circumstances giving rise to the
                  claim.

     4.11  The Purchaser shall have no right to recover in respect of any Claim
           unless and until the aggregate liability of the Warrantors (but for
           this paragraph) in respect of all Claims would exceed (Pounds)50,000,
           but, if such aggregate liability should exceed that sum, the Vendors
           or ITS (as the case may be) shall be liable for the full amount of
           such liability and not just the excess over that amount.

     4.12  The Purchaser shall have no right to recover in respect of any
           individual Claim in respect of which the liability of the Vendors or
           ITS (as the case may be) (but for this paragraph) would not exceed
           (Pounds)5,000 but such Claim shall not be

                                                                      Warranties

           discounted in calculating the aggregate liability of the Warrantors 
           for the purposes of Clause 4.10.

     4.13  The liability of each of the Vendors under this Clause 4 shall be
           joint and several and the liability as between ITS and the Vendors
           together shall be several.

     4.14  The maximum liability of the Vendors and ITS in respect of all Claims
           shall not exceed in each case the amount received by way of
           consideration by each of the them save where the facts or
           circumstances giving rise to such Claim are such as to permit the
           Purchaser to allege fraud on behalf of the Vendors or ITS (as the
           case may be) when the liability shall be without limit.

     4.15  The liability of the Vendors and ITS in relation to the Warranties
           shall cease on 31 August 1998 save as regards any alleged specific
           breach of which notice in writing has been given to the Vendor or ITS
           (as appropriate) prior to that date.

     4.16  The Vendors agree with the Purchaser that, during the period between
           exchange of this agreement and Completion, they will procure that:

           4.16.1  the Company does not depart from the ordinary course of the
                   conduct of its business as conducted in the financial year
                   ending on the Balance Sheet Date;

           4.16.2  that the Company shall not (without prejudice to sub-clause
                   4.16.1):
 
                   4.16.2.1   incur, or enter into any commitment to incur, any
                              capital expenditure;
 
                   4.16.2.2   dispose of, or agree to dispose of, or grant any
                              rights in respect of, any of its fixed assets;

                   4.16.2.3   enter into any abnormal contract or commitment;
 
                   4.16.2.4   declare, make or pay any dividend or other
                              distribution;

                                                                      Warranties


           4.16.3 no resolution of the shareholders of the Company is passed.

     4.17  The Vendors undertake to notify the Purchaser immediately upon
           becoming aware before Completion of any matter or thing which
           constitutes a breach of Clause 4.16 or which is inconsistent with any
           of the Warranties or which might make any of them inaccurate or
           misleading or which is relevant to be disclosed in respect of them.

     4.18  In the event that the Vendors make a notification pursuant to Clause
           4.17 or the Company fails to comply with provisions of Clause 4.16 or
           the Purchaser otherwise becomes aware that any of the Warranties is
           inaccurate or misleading the Purchaser shall at its absolute
           discretion either:

           4.18.1  proceed to Completion in accordance with Clause 5 whereupon 
                   it shall have no other remedy pursuant to this Agreement in
                   respect of the matters referred to in this Clause; or

           4.18.2  by notice to the Vendors and ITS rescind this Agreement such
                   rescission to be without prejudice to any rights it may have
                   pursuant to this Agreement or otherwise.

     4.19  The Purchaser shall be entitled to set off any sums payable or
           alleged to be payable by the Vendors or either of them under any of
           the Warranties or under the Tax Covenant against any sums which would
           otherwise be payable by the Purchaser upon redemption of the Bond.
           The provisions of this clause 4.19 shall take precedence over any
           provision to the contrary whether express or implied, contained in
           the Bond.

           officer or employee of the Company who needs that knowledge in the
           discharge of his duties) any confidential information concerning the
           business, customers, accounts, financial or contractual arrangements,
           transactions or affairs of the Company which may be within or come to
           its knowledge to the extent and so long as that information is
           confidential and not in the public domain and that the said Vendor
           will use all reasonable endeavours to prevent the publication or
           disclosure of any such confidential information.

           possession or under their control relating to the business and

           or procure the giving to the Purchaser and those authorised by it
           such access (including the right to take copies) to any records

                                DEED OF COVENANT
                                ----------------

This Deed of Covenant (this "Deed") dated                      1996 made between
Uniphase Corporation ("Uniphase"), a Delaware corporation, and Jonathan Timothy
Greaves and Wendy Greaves (the "Principal Shareholders").

Pursuant to an Agreement dated as of         June 1996 (the "Purchase
Agreement"), by and among Uniphase, Industrial Technology Securities Limited,
(registered in England under company number 1792376), and the Shareholders of
GCA Fibreoptics Limited ("GCA"), Uniphase is acquiring the entire issued shares
in GCA.  Capitalised terms used herein and not otherwise defined have the
meanings assigned to them in the Purchase Agreement.

The Principal Shareholders have agreed in paragraph of 1.4 of Schedule 4 of the
Purchase Agreement to execute and deliver to Uniphase at the Completion Date a
Deed of Covenant.

THE PARTIES HERETO AGREE AS FOLLOWS:

1.   NON-COMPETE OBLIGATION
     ----------------------

     1.1   The Principal Shareholders hereby agree and covenant that for a 
           period of three years after the Completion Date each of them shall 
           neither directly nor indirectly:

           1.1.1  make known to any person the names and addresses of any of the
                  customers of GCA or any other information pertaining to them;

           1.1.2  take away any of the customers of GCA on whom he has called,
                  or with whom he has dealt or become acquainted with, either 
                  for himself or for any other person.

           1.1.3  accept a position with or otherwise become affiliated with,
                  any other person for the purpose of competing with Uniphase's
                  business.  Each Principal Shareholder acknowledges and
                  understands that this provision not to compete is necessary to
                  protect GCA's and Uniphase's trade secrets, proprietary
                  information,

                                       1
<PAGE>
 
                  confidential information, and know-how by avoiding such
                  situations which would inherently create a fraud with the
                  potentiality of intentional or unintentional revelations of
                  such trade secrets, information and know-how.

           1.1.4  interfere with the business of Uniphase in any manner
                  whatsoever including, without limitation, recruiting or hiring
                  employees of Uniphase or ex-employees of GCA or Uniphase whose
                  employment with employer was terminated less than one (1) year
                  prior to the date of such interference.

2.   SPECIFIC PERFORMANCE
     --------------------

          Each Principal Shareholder acknowledges that any violation of the
     provisions of this Agreement would cause irreparable damage for which
     monetary damages would be inadequate and therefore agrees that Uniphase
     shall have the right to obtain, in addition to all other remedies it may
     have, such injunctive and other equitable relief from a court of competent
     jurisdiction as may be necessary or appropriate to prevent or remedy any
     violation of this Agreement.

3.   GOVERNING LAW
     -------------

          This Agreement is governed by the laws of England and shall inure to
     the benefit of and be binding upon the successors, assigns, heirs and
     personal representatives of the parties hereto.

4.   COUNTERPARTS: AMENDMENTS
     ------------------------

          This Agreement may be executed in one or more counterparts, all of
     which documents shall be considered one and the same document. This
     Agreement may not be changed, amended or modified, in whole or in part,
     except by written agreement signed by all parties.

          requires otherwise, words, expressions and abbreviations shall have

    1.2   In this deed, unless the context requires otherwise:

               "Agreement" means the agreement of even date with this deed 
          between the Covenantors and the Purchaser for the sale and purchase 
          of the Sale Shares;

               "claim" means the issue of any notice, letter or other document
          by or on behalf of any Tax Authority or the taking of any other 
          action by or on behalf of any Tax Authority from which notice, letter,
          document or action it appears that a Tax liability is to be, or may 
          come to be, imposed on the Company;

                                       1
<PAGE>
 
               "Covenantors' Relief" means any Relief which:

                    (a)   arises as a consequence of any Event occurring on or 
          before the Accounts Date and not by reference to or in consequence 
          of any Event occurring after the Accounts Date; and

                    (b)   is not a Relief or right to repayment of Taxation 
          which has been treated as an asset in the Accounts or taken into 
          account in computing (and so reducing any provision for deferred Tax).

               "event" means any event including any transaction, action or
          omission, any change in the residence of any person for the purposes
          of any Tax, the death of any person, any failure to take any action
          which would avoid an apportionment or deemed distribution of income
          (regardless of whether the taking of any such action after Completion
          could have avoided such apportionment or deemed distribution), and
          shall also include Completion;

               "Relief" means any relief, allowance or credit in respect of any
          Tax or deduction in computing income, profits or gains for the
          purposes of any Tax;

               "Tax assessment" means any assessment, demand or other similar
          formal notice of a Tax liability issued by or on behalf of any Tax
          Authority by virtue of which the Company either is liable to make a
          payment of Tax or will, with the passing of time, become so liable (in
          the absence of any successful application to postpone any such
          payment).

    1.3   In this deed, reference to any "Tax liability" of the Company means a
          liability of the Company to make actual payments of Tax and also:

          1.3.1  the loss, or the setting-off against income, profits or gains
                 earned or accrued before Completion (where, but for such
                 setting-off, the Company would have had an actual Tax liability
                 in respect of which the Purchaser would have been able to make
                 a claim against the Covenantors under this deed), of any Relief

                                       2
<PAGE>
 
                 which would (were it not for the said loss or setting-off) have
                 been available to the Company and which has been taken into
                 account in computing (and so reducing) any provision for
                 deferred Tax which appears in the Audited Accounts (or which,
                 but for the presumed availability of such Relief would have
                 appeared in the Audited Accounts);

          1.3.2  the loss of a right to repayment of Tax which has been treated
                 as an asset of the Company in preparing the Audited Accounts or
                 the setting-off of any right to repayment of Tax against any
                 actual Tax liability in respect of which the Purchaser would,
                 but for that setting-off, have been able to make a claim
                 against the Covenantors under this deed; and

          1.3.3  the setting-off against income, profits or gains earned, 
                 accrued or received on or before Completion of any Relief which
                 arises in respect of an event occurring after Completion and
                 not in respect of any event occurring on or before Completion
                 in circumstances where, but for such setting-off, the Company
                 would have had an actual Tax liability in respect of which the
                 Purchaser would have been able to make a claim against the
                 Covenantors under this deed,

                     and, in such a case, the amount of Tax which could
          otherwise have been relieved, allowed, exempted or credited by the
          Relief so lost or set off, or the amount of repayment which would
          otherwise have been obtained, shall be treated as the amount of a Tax
          liability which has arisen.

    1.4   In this deed, reference to:

          1.4.1  "income, profits or gains" includes any such income, profits or
                 gains which are deemed to be earned, accrued or received for
                 the purposes of any Tax;

          1.4.2  income, profits or gains (as defined in sub-clause 1.4.1) as
                 being earned, accrued or received on or before a particular
                 date or in respect of a particular period includes income,
                 profits or gains which are deemed to have been earned, accrued

                                       3
<PAGE>
 
                 or received on or before that date or in respect of that period
                 for the purposes of any Tax;

          1.4.3  any payment or distribution as being made on or before a
                 particular date includes:

                 1.4.3.1  any payment or distribution which has fallen due to be
                          made on or before that date; and

                1.4.3.2   any event which has occurred on or before that date 
                          and is, or is deemed to be, a payment or distribution

               for (in either such case) the purposes of any Tax.

2.  COVENANT TO PAY
    ---------------

         Subject to the provisions of clause 3, the Covenantors covenant 
    jointly and severally (on behalf of themselves and their respective personal
    legal representatives) with the Purchaser (for itself and as trustee for its
    successors in title) that they shall pay to the Purchaser or at the option
    of the Purchaser as the Purchaser shall direct a sum equal to any of the
    following:

    2.1   any Tax liability of the Company arising:

          2.1.1  as a consequence of or by reference to any event which occurred
                 on or before Completion or was deemed to occur on or before
                 Completion for the purposes of any Tax; or

          2.1.2  in respect of or by reference to any income, profits or gains
                 which were earned, accrued or received on or before Completion
                 or in respect of a period ending on or before Completion;

    2.2   any depletion in the assets or increase in the liabilities of the
          Purchaser or the Company as a result of any Inheritance Tax which is,
          at the Completion Date, a charge on any of the shares or assets of the
          Company or gives rise to a power to sell, mortgage or charge any of

                                       4
<PAGE>
 
          the shares or assets of the Company; or, after the Completion Date,
          becomes a charge on or gives rise to a power to sell, mortgage or
          charge any of the shares or assets of the Company being a liability in
          respect of Inheritance Tax payable as a result of the death of any
          person within seven years after a transfer of value if a charge on or
          power to sell, mortgage or charge any such shares or assets existed at
          the Completion Date or would, if the death had occurred immediately
          before the Completion Date and the Inheritance Tax payable as a result
          thereof had not been paid, have existed at the Completion Date or
          arises as a result of a transfer of value made on or before Completion
          by or to the Company AND FOR THE AVOIDANCE OF DOUBT, any payment made
          by the Purchaser or the Company to discharge or remove any charge or
          power to sell, mortgage or charge shall give rise to a depletion in
          the assets of the Purchaser or the Company and there shall be ignored
          any right of the Purchaser or the Company to pay Inheritance Tax in
          instalments and any right which the Covenantors may have to pay any
          amount due under this deed by instalments;

    2.3   any costs and expenses reasonably and properly incurred by the
          Purchaser or the Company in connection with any such Tax liability as
          is mentioned in clauses 2.1 or 2.2  or with any claim for them or in
          taking or defending any action under this deed.

3.  LIMITS TO COVENANT
    ------------------

    3.1   The covenant given by clause 2 shall not apply to any Tax liability of
          the Company to the extent that:

          3.1.1  provision or reserve in respect of that Tax liability was made
                 in the Audited Accounts;

          3.1.2  that Tax liability arises or is increased as a result only of
                 any increase in rates of Tax made after Completion with
                 retrospective effect or of any change in law occurring after
                 Completion with retrospective effect,

          3.1.3  the Tax liability arises as a result of transactions in the
                 ordinary course of business since the Accounts Date;

                                       5
<PAGE>
 
          3.1.4  such Tax liability would not have arisen but for a voluntary 
                 act carried out by the Purchaser or the Company after the date
                 of this Deed being an act which:

                 3.1.4.1  is not in the ordinary course of business of the
                          Company as carried on at the date of this Deed or
                          otherwise than pursuant to a legally binding
                          obligation created on or before the date hereof; and

                 3.1.4.2  the Purchaser knew or should have known would give
                          rise to a Taxation liability and the Covenantors did
                          not expressly or impliedly consent;

          3.1.5  such Tax liability arises directly as a result of the change of
                 the date to which the Company makes up its accounts;

          3.1.6  such Tax liability arises as a result only of any change after
                 Completion in the accounting policies of the Company other than
                 any such change or changes which are necessary to bring such
                 accounting policies into line with the SSAPs and FRSs which are
                 in force at Completion;

          3.1.7  a Covenantors' Relief is available to reduce such Tax liability
                 and has not previously been taken into account under this
                 clause 3.1.7.
 
    3.2   The provisions of clauses 4.11, 4.12 and 4.14 of the Agreement shall
          apply in respect of claims made under clause 2 of this Deed as if the
          same were set out in full herein.

    3.3   The liability of the Covenantors under this Tax Covenant and the Tax
          Warranties shall determine on the seventh anniversary of Completion.

    3.4   If after the Covenantors have satisfied in full any liability under
          this Tax Covenant the Company or the Purchaser receives a benefit or
          makes an actual saving which it would not 

                                       6
<PAGE>
 
          have received or made but for the circumstances giving rise to that
          claim under this Tax Covenant then the Purchaser shall use reasonable
          endeavours to procure that:-

          3.4.1  reasonable details of the benefit or saving are given to the
                 Covenantors as soon as reasonably practicable;

          3.4.2  any payment already made by the Covenantors in respect of the
                 claim is forthwith repaid to the Covenantors.

4.  RELIEFS
    -------

    4.1   If the auditors for the time being of the Company shall certify (at
          the request and expense of the Covenantors) that any Tax liability
          which has resulted in a payment having been made or becoming due from
          the Covenantors under this deed will give rise to a Relief for the
          Company which would not otherwise have arisen, then, as and when the
          liability of the Company to make an actual payment of or in respect of
          Tax is reduced by reason of that Relief and after taking account of
          the effect of all other Reliefs that are or become available to the
          Company (including any Relief derived from a subsequent accounting
          period), the amount by which that liability is so reduced shall be
          dealt with in accordance with clause 4.2.

    4.2   Where it is provided under clause 4.1 that any amount (the "Relevant
          Amount") is to be dealt with in accordance with this clause:

          4.2.1  the Relevant Amount shall first be set off against any payment
                 then due from the Covenantors under this deed;

          4.2.2  to the extent that there is an excess, a refund shall be made
                 to the Covenantors of any previous payment or payments made by
                 the Covenantors under this deed and not previously refunded
                 under this clause 4 up to the amount of such excess; and

          4.2.3  to the extent that the excess referred to in sub-clause 4.2.2
                 is not exhausted under that sub-clause, the remainder of that
                 excess shall be carried forward and set off 

                                       7
<PAGE>
 
                 against any future payment or payments which become due from 
                 the Covenantors under this deed.

    4.3   Where any such certification as is mentioned in clause 4.1 has been
          made, the Covenantors or the Purchaser or the Company may request the
          auditors for the time being of the Company to review such
          certification in the light of all relevant circumstances, including
          any facts which have become known only since such certification, and
          to certify whether such certification remains correct or whether, in
          the light of those circumstances, the amount that was the subject of
          such certification should be amended.

    4.4   If the auditors certify under clause 4.3 that an amount previously
          certified should be amended, that amended amount shall be substituted
          for the purposes of clause 4.2 as the Relevant Amount in respect of
          the certification in question in place of the amount originally
          certified, and such adjusting payment (if any) as may be required by
          virtue of the above-mentioned substitution shall be made as soon as
          practicable by the Covenantors or (as the case may be) to the
          Covenantors.

5.  RECOVERY FROM OTHER PERSONS
    ---------------------------

         If, in the event of any payment becoming due from the Covenantors 
    pursuant to clause 2, the Company either is immediately entitled at the due
    date for the making of that payment to recover from some other person (not
    being the Company but including any Tax Authority) any sum in respect of the
    Tax liability that has resulted in that payment becoming due from the
    Covenantors, or at some subsequent date becomes entitled to make such a
    recovery, then the Company being entitled to make that recovery shall (in
    either of those cases) promptly notify the Covenantors of their entitlement
    and shall, if so required by the Covenantors and at the Covenantors sole
    expense, take all appropriate steps to enforce that recovery (keeping the
    Covenantors fully informed of the progress of any action taken) and shall
    account to the Covenantors for, or where the Covenantors have not yet made
    the payment due under this deed the amount due shall be reduced by,
    whichever is the lesser of:

    5.1   any sum so recovered (including any interest or repayment supplement
          paid by the Tax Authority or other person on or in respect of it less
          any Tax chargeable on the Company in respect of that interest); and

                                       8
<PAGE>
 
    5.2   the amount paid by or due from (as the case may be) the Covenantors
          pursuant to clause 2 in respect of the Tax liability in question.


6.  CLAIMS PROCEDURE
    ----------------

    6.1   Upon the Purchaser or the Company becoming aware of a claim relevant
          for the purposes of this deed, it shall, so soon as may be
          practicable, give notice of it to the Covenantors, and the Company
          shall (if the Covenantors shall indemnify and secure the Company to
          its reasonable satisfaction against all losses, costs, damages and
          expenses including interest on overdue Tax, which may be incurred in
          so doing) take such action and give such information and assistance in
          connection with the affairs of the Company as the Covenantors may
          reasonably and promptly by written notice request to avoid, resist,
          appeal or compromise the claim; PROVIDED THAT the Company shall not be
          obliged to appeal against any Tax assessment raised on it if, having
          given the Covenantors written notice of the receipt of that Tax
          assessment, it has not, within 14 days after that, received
          instructions in writing from the Covenantors, in accordance with the
          preceding provisions of this clause, to make that appeal; AND PROVIDED
          FURTHER THAT the Company shall not be obliged to take any action under
          this clause which involves contesting any Tax assessment before any
          court or other appellate body (excluding the authority or body
          demanding the Tax in question) unless the Covenantors furnishes the
          Company with the written opinion of leading Tax Counsel or senior
          junior Counsel to the effect that an appeal against the Tax assessment
          in question shall, on the balance of probabilities, be won.

    6.2   The actions which the Covenantors may reasonably request under clause
          6.1 shall include  the Company applying to postpone (so far as legally
          possible) the payment of any Tax and/or allowing the Covenantors to
          take on or take over at their own expense the conduct of all or any
          proceedings of whatever nature arising in connection with the claim in
          question, PROVIDED THAT if the Covenantors takes on or takes over the
          conduct of proceedings:

                                       9
<PAGE>
 
          6.2.1  the Purchaser and the Company shall provide such information 
                 and assistance as the Covenantors may reasonably require in
                 connection with the preparation for and conduct of those

<PAGE>
 
          mentioned in this clause 7.2 in relation to any tax return that

    7.3   Nothing done by the Company pursuant to this clause 7 shall in any

          8.1.1  in a case which involves an actual payment of Tax by the
                 Company, the date which is the later of seven days after
                 notification by the Company or the Purchaser of the amount due
                 and seven days before the last date on which the Tax is due and
                 payable to the appropriate Tax Authority in order to avoid
                 incurring a liability to interest or a charge or penalty in
                 respect of that Tax liability;

          8.1.2  in a case falling within clause 1.3.1, the date falling seven
                 days after the date when the Covenantors have been notified by
                 the Company or the Purchaser that the auditors for the time
                 being of the Company have certified, at the request of the
                 Purchaser or the Company, that the Covenantor(s) have a
                 liability for a determinable amount under clause 2; or
 
          8.1.3  in case falling within clause 1.3.2, the later of seven days
                 after notification by the Company or the Purchaser of the

                 after notification by the Company or the Purchaser of the
                 amount due and seven days before the date on which the Tax
                 which has been saved by reason of the setting-off of the Relief
                 would otherwise have been payable to the Tax Authority in order
                 to avoid 

                                      11
<PAGE>
 
                 incurring a liability to interest or a charge or penalty in 
                 respect of that Tax liability.
                 
          8.1.5  in a case falling within clause 2.3, within seven days of

    8.2   If any payment required to be made by the Covenantors under this deed
          is not made by the due date for making it, then, except to the extent
          that the Covenantors liability under clause 2 compensates the
          Purchaser for the late payment by virtue of its extending to
          interest and penalties, that payment shall carry interest from that
          due date until the date when the payment is actually made at the rate
          of 2 per cent above the base rate from time to time of Lloyds Bank
          PLC.


9.  PURCHASER'S FURTHER OBLIGATION

    until such time as the Covenantors shall cease to have any Tax Liability
    pursuant to this Tax Covenant.

10. DEDUCTIONS FROM PAYMENTS

    10.2  If any deductions or withholdings are required by law to be made from
          any of the sums payable as mentioned in clause 9.1, the Covenantors

          with the same amount as it would have been entitled to receive in the
          absence of any such requirement to make a deduction or withholding.

    10.3  If any sum payable by the Covenantors under this deed (other than

                                      12
<PAGE>
 
          under the same obligation to make an increased payment in relation

                                DEED OF COVENANT
                                ----------------

This Deed of Covenant (this "Deed") dated                      1996 made between
Uniphase Corporation ("Uniphase"), a Delaware corporation, and Jonathan Timothy
Greaves and Wendy Greaves (the "Principal Shareholders").

Pursuant to an Agreement dated as of         June 1996 (the "Purchase
Agreement"), by and among Uniphase, Industrial Technology Securities Limited,
(registered in England under company number 1792376), and the Shareholders of
GCA Fibreoptics Limited ("GCA"), Uniphase is acquiring the entire issued shares
in GCA.  Capitalised terms used herein and not otherwise defined have the
meanings assigned to them in the Purchase Agreement.

The Principal Shareholders have agreed in paragraph of 1.4 of Schedule 4 of the
Purchase Agreement to execute and deliver to Uniphase at the Completion Date a
Deed of Covenant.

THE PARTIES HERETO AGREE AS FOLLOWS:

1.   NON-COMPETE OBLIGATION
     ----------------------

     1.1  The Principal Shareholders hereby agree and covenant that for a period
          of three years after the Completion Date each of them shall neither
          directly nor indirectly:

          1.1.1  make known to any person the names and addresses of any of the
                 customers of GCA or any other information pertaining to them;

          1.1.2  take away any of the customers of GCA on whom he has called,
                 or with whom he has dealt or become acquainted with, either for
                 himself or for any other person.

          1.1.3  accept a position with or otherwise become affiliated with,
                 any other person for the purpose of competing with Uniphase's
                 business.  Each Principal Shareholder acknowledges and
                 understands that this provision not to compete is necessary to
                 protect GCA's and Uniphase's trade secrets, proprietary
                 information, 

                                       1
<PAGE>
 
                 confidential information, and know-how by avoiding such
                 situations which would inherently create a fraud with the
                 potentiality of intentional or unintentional revelations of
                 such trade secrets, information and know-how.

          1.1.4  interfere with the business of Uniphase in any manner
                 whatsoever including, without limitation, recruiting or hiring
                 employees of Uniphase or ex-employees of GCA or Uniphase whose
                 employment with employer was terminated less than one (1) year
                 prior to the date of such interference.

2.   SPECIFIC PERFORMANCE
     --------------------

          Each Principal Shareholder acknowledges that any violation of the
     provisions of this Agreement would cause irreparable damage for which
     monetary damages would be inadequate and therefore agrees that Uniphase
     shall have the right to obtain, in addition to all other remedies it may
     have, such injunctive and other equitable relief from a court of competent
     jurisdiction as may be necessary or appropriate to prevent or remedy any
     violation of this Agreement.

3.   GOVERNING LAW
     -------------

          This Agreement is governed by the laws of England and shall inure to
     the benefit of and be binding upon the successors, assigns, heirs and
     personal representatives of the parties hereto,

4.   COUNTERPARTS: AMENDMENTS
     ------------------------

          This Agreement may be executed in one or more counterparts, all of 
     which documents shall be considered one and the same document.  This 
     Agreement may not be changed, amended or modified, in whole or in part, 
     except by written agreement signed by all parties.

5.   NOTICES
