Gentlemen:

     1. Subscription JDS Uniphase Corporation, a Delaware corporation (the

(a) 2,684,211 shares of Series D Preferred Stock, par value $.0001 per share, of
the Company (the "Shares"), at a purchase price of $1.90 per Share and (b) a
Convertible Promissory Note in the principal amount of $5,100,000 (the
"Convertible Note"). The number of Shares and the Convertible Note subscribed
for pursuant to this Subscription Agreement equal the number of Shares and the
principal amount of the Convertible Note intended to be issued and purchased
pursuant to that certain Settlement Agreement, dated as of June 25, 2003, by and
between the Company and the Purchaser (the "Settlement Agreement"). Together
with this Subscription Agreement, the Purchaser is delivering completed and
executed signature pages to the Series D Preferred Stockholders Agreement
between the Company and the Purchaser (the "Series D Preferred Stockholders
Agreement"), and the Registration Rights Agreement between the Company and the
Purchaser (the "Registration Rights Agreement").

     2. Payment. The Purchaser and the Company agree that the consideration for
the Shares and the Convertible Note subscribed for pursuant to this Agreement
shall solely consist of the release and settlement of claims by the Purchaser as
described in the Settlement Agreement and that no other consideration shall be
due or owing with respect to the purchase price for the Shares and the
Convertible Note.

     3. Purchaser Representations and Warranties. The Purchaser hereby
represents and warrants to the Company, acknowledges and agrees as follows:

          (a) The Purchaser is purchasing the Shares and the Convertible Note
     for its own account, for investment only and not with a view to, or any
     present intention of, effecting a distribution of such securities or any
     part thereof except pursuant to a registration or an available exemption
     under applicable law. The Purchaser acknowledges that the Shares and the
     Note have not been, the shares of Series D Convertible Preferred Stock of
     the Company issuable upon conversion of the Convertible Note (the
     "Conversion Shares"), and shares of Common Stock, par value $.0001 per
     share, of the Company (the "Common Shares"), issuable upon conversion of
     the Shares or the Conversion Shares (the Shares, the Note, the Conversion
     Shares together with the Common Stock, the "Securities"), will not be,
     registered under the Securities Act of 1933, as amended (the "Securities
     Act"), or the securities laws of any state or other jurisdiction and cannot
     be disposed of unless they are subsequently registered under the Securities
     Act and any applicable state laws or an exemption from such registration is
     available.

<PAGE>

          (b) Neither the Securities and Exchange Commission, any state
     securities commission nor any other regulatory authority has approved the
     Securities or passed upon or endorsed the merits of the sale of the Shares
     or the Convertible Note or confirmed the accuracy or determined the
     adequacy of any materials of the Company submitted to you. Any
     representation to the contrary is unlawful.

          (c) The Purchaser is unaware of, is in no way relying on, and did not
     become aware of the offering of the Shares or the Convertible Note through
     or as a result of, any form of general solicitation or general advertising
     including, without limitation, any article, notice, advertisement or other
     communication published in any newspaper, magazine or similar media or
     broadcast over television or radio, in connection with the sale of the
     Shares or the Convertible Note and is not subscribing for Shares or the
     Convertible Note and did not become aware of the sale of the Shares or the
     Convertible Note through or as a result of any seminar or meeting to which
     the Purchaser was invited by, or any solicitation of a subscription by, a
     person not previously known to the Purchaser in connection with investments
     in securities generally.

          (d) The Purchaser understands that the exemption from registration
     afforded by Rule 144 (the provisions of which are known to the Purchaser)
     promulgated under the Securities Act depends on the satisfaction of various
     conditions and that, if applicable, Rule 144 may only afford the basis for
     sales under certain circumstances and only in limited amounts.

          (e) The Purchaser is an "accredited investor," as such term is defined
     in Rule 501 (the provisions of which are known to the Purchaser)
     promulgated under the Securities Act. The Purchaser has such knowledge and
     experience in financial, tax and business matters so as to enable the
     Purchaser to utilize the information made available to it in connection
     with the investment in the Shares and the Convertible Note, to evaluate the
     merits and risks of an investment in the Shares and the Convertible Note,
     and to make an informed investment decision with respect thereto.

          (f) The Purchaser hereby acknowledges and agrees that the purchase and
     sale of the Shares and the Convertible Note is intended to be exempt from
     registration under the Securities Act by virtue of Section 4(2) of the
     Securities Act, and, if applicable, in the sole judgment of the Company,
     the provisions of Regulation D thereunder, which exemption is dependent
     upon the truth, completeness and accuracy of the statements made by the
     Purchaser herein and in any other documents furnished by the Purchaser to
     the Company. The Purchaser acknowledges and agrees that it will not sell or
     transfer all or any part of the Shares or the Convertible Note or the
     Convertible Note except in accordance with the terms of the Series D
     Preferred Stockholders Agreement.

          (g) The Purchaser has full right, authority and power under its
     charter and by-laws to enter into this Subscription Agreement, the Series D
     Preferred Stockholders Agreement, the Registration Rights Agreement, the
     Note, and the Amendment to Stockholders Agreement by and among the Company,
     the Purchaser, the Founders and the holders of

     to or affecting creditors' rights and to general principles of equity,
     including principles of commercial reasonableness, good faith and fair
     dealing. The execution, delivery and performance of the Transaction
     Documents have been duly authorized by all necessary action under the
     Purchaser's charter or by-laws. The execution, delivery and performance by
     the Purchaser of the Transaction Documents do not and will not: (i) violate
     or result in a violation of, conflict with or constitute or result in a
     default (whether after the giving of notice, lapse or time or both) under,
     accelerate any obligation under, or give rise to a right of termination of,
     any material contract, agreement, lease, obligation, permit, license or
     authorization to which the Purchaser is a party or by which the Purchaser
     or its assets is bound, or any provision of such Purchaser's organizational
     documents; (ii) violate or result in a violation of, or constitute a
     default (whether after the giving of notice, lapse of time or both) under,
     any provision of any law, regulation or rule, or any order of, or any
     restriction imposed by, any court or governmental agency applicable to the
     Purchaser; or (iii) require from the Purchaser any notice to, declaration
     or filing with, or consent or approval of, any governmental authority or
     other third party.

          (h) The Purchaser is not relying on the Company or any of its
     respective employees, attorneys or agents with respect to the legal, tax,
     economic and related considerations of an investment in the Shares or the
     Convertible Note, and the Purchaser has relied on the advice of, or has
     consulted with, only its own attorney, accountant, purchaser representative
     and/or tax advisor.

     4. Company Representations and Warranties. The Company hereby represents
and warrants to the Purchaser as follows:

of June 25, 2003, by and among JDS UNIPHASE CORPORATION, a Delaware corporation
("JDSU" or "Claimant"), and IPG PHOTONICS CORPORATION, a Delaware corporation

                                   WITNESSETH:

          A. IPG and JDSU's predecessor in interest, SDL Inc., a Delaware
corporation ("SDL"), entered into a purchase and sale agreement entitled IPG
Photonics Corporation Purchase and Sale Agreement No. 1-99, dated May 11, 1999,
which was subsequently amended by the parties on or about May 18, 2000 and
amended a second time on or about November 15, 2000 (collectively, the

          C. JDSU has commenced an arbitration proceeding against IPG before the
American Arbitration Association, entitled JDS Uniphase Corporation against IPG
Photonics Corporation, AAA Number 74 181 01636 02, now pending before the AAA
San Jose Regional Office (the "Arbitration"), alleging that IPG has breached the
Agreement and now owes JDSU in excess of $10 million;

          D. JDSU also commenced a proceeding against IPG in Massachusetts state
court, entitled JDSU Uniphase Corp. v. IPG Photonics Corp., No. 02-1780, now
pending before the Superior Court of the Commonwealth of Massachusetts
requesting, among other things, equitable relief in the form of an attachment of
IPG's assets in Massachusetts (the "State Court Action").

          E. IPG has asserted counterclaims against JDSU and SDL in the

competition and violation of federal and state laws governing anti-trust and
unfair competition;

          F. Both parties have denied the others' operative allegations

IPG; and

          G. IPG and JDSU each believes that it will be best served by ending
the disputes reflected in the Arbitration and the State Court Action and that
the continued prosecution of the Arbitration and the State Court Action will
entail the expenditure of substantial legal fees and management time for both
IPG and JDSU over the course of several years, resources that each of them
believes would be better spent in pursuit of such business interest; and

          H. Subject to the terms of this Settlement and the other instruments
and documents to be entered into by it pursuant hereto, JDSU is therefore
willing to dismiss the claims it has asserted against IPG in the Arbitration and
the State Court Action, and IPG is willing to dismiss the counterclaims that it
has asserted against JDSU in the Arbitration and the State Court Action; and

          and conditions of this Settlement.

     C.   Upon the Closing, IPG and JDSU shall cause their respective attorneys
          to execute a Stipulation and Order of Dismissal to dismiss the action
          entitled JDS Uniphase Corp. v. IPG Photonics Corp., No. 02-1780,

3.   Structured Cash Payment to JDSU.

     A.   Promissory Note.

          Exhibit A attached hereto in the principal amount of $6,079,472.60
          (Six million, seventy nine thousand, four hundred and seventy two

          and unpaid interest under the Note shall be payable at the same times
          as payments of principal.

          At the Closing, IPG shall pay to JDSU $302,006.30 (which amount
          represents a payment to JDSU of $334,000 less $31,993.70 for an
          outstanding account payable of JDSU owing to IPG).

     B.   Attachment: The Note shall be secured by a first priority security
          interest in certain IPG's assets set forth in the Security Agreement
          (the "Security Agreement") in the form of Exhibit B attached hereto,
          and in certain land owned by IPG set forth in the Mortgage (the
          "Mortgage") in the form of Exhibit C attached hereto. JDSU and IPG
          shall execute the Security Agreement and IPG shall execute the
          Mortgage concurrently with the execution of this Settlement.

     C.   Release of Liens: At or promptly following the Closing, JDSU shall
          release its liens and attachment on the assets of IPG under the Writ
          of Attachment, dated February 28, 2003 (Superior Court Department of
          the Trial Court Civil Action 02-1780C); it being agreed that the
          assets subject to such Writ of Attachment shall become the assets
          which shall the Note pursuant to the Security Agreement and the
          Mortgage.

     D.   Acceleration. The amounts set forth in Section 3(A) shall be

          occurrence of any of the following events:

          i.   IPG shall have defaulted in the performance of its obligations
               under the Note and shall have failed to cure such default within
               thirty (30) days of written notice thereof given by JDSU in
               accordance with terms of the Note; and

          ii.  A Change of Control of IPG, as defined in the Note.

     E.   Other Prepayments.

          i.   In the event that IPG engages in an equity financing prior to
               repayment and satisfaction of the Note, it shall provide to JDSU
               in payment of the Note 10% of any net proceeds raised through
               such financing; or

          ii.  In the event that IPG's commercial bank (BankNorth) releases to
               IPG any cash collateral currently held by it, IPG shall provide
               those funds to JDSU in payment of the Note as follows:

                                       4

<PAGE>

               a.   If the release occurs during 2003 or 2004, then IPG shall
                    pay JDSU 50% of such released cash in partial payment of the
                    Note; and

               b.   If the release occurs during 2005, IPG shall pay to JDSU 75%
                    of such released cash in partial payment of the Note, until
                    such Note is paid in full.

          All prepayments shall be applied in the reverse order of principal
payments under the Note.

     F.   Disposition of assets. IPG shall be permitted to sell, transfer or
          otherwise dispose of the assets securing the Note from time to time,
          provided that (a) the assets are sold for fair value, and (b) that the
          net consideration received by IPG in connection with the sale of the
          assets are used within five (5) business days of the receipt thereof
          to prepay the Note. All payments under this Section F shall be applied

4.   Commercial Relationship.

     A.   Concurrently with the execution of this Settlement, IPG and JDSU shall
          execute (a) a Master Supply Agreement, in the form of Exhibit D
          attached hereto, pursuant to which IPG agrees that it will supply to
          JDSU, pulsed Ytterbium fiber laser modules (current and new commercial
          versions) that it sells on the merchant market, excluding those fiber
          lasers as to which IPG is subject to exclusivity obligations and (b) a
          Master Supply Agreement under which JDSU agrees to supply to IPG, and
          IPG agrees to purchase from JDSU on the terms and conditions set forth
          in Exhibit E, commercially available Laser Diodes and packaged Laser
          Diodes that it sells on the merchant market.

5.   Investment By JDSU.

Promptly following the execution of this Settlement, IPG and JDSU will negotiate
in good faith to document and effectuate the general terms set forth below
governing the terms of a new series of convertible preferred stock of IPG (the
"Series D Preferred") and a convertible note (the "Convertible Note") to be to
be issued to JDSU at the Closing. The parties hereto agree that IPG shall
provide to JDSU drafts of the principal documents incorporating the terms of the
Series D Preferred and Convertible Note (collectively, the "Equity Documents")
to JDSU not later than three business days following the execution of this
Settlement. It is the goal of the parties hereto to execute and deliver the
Equity Documents (including obtaining all necessary approvals and consents,
which IPG agrees to request in good faith) not later than three weeks following
the execution of this Settlement. The terms of the Equity Documents shall
reflect the following:

     A.   IPG would provide a new series of convertible preferred stock, the
          Series D Preferred, having a $5,100,000 liquidation preference. IPG
          would issue the Series D Preferred representing 5% of IPG outstanding
          shares (fully diluted, including accounting for weighted average
          ratchet and warrant positions) to JDSU.

          i.   The liquidation preference and price per share would be $1.90 per
               share (equal to $5,100,000);

                                       5

<PAGE>

          ii.  Series D Preferred rights and preferences would be substantially
               similar to Series A Preferred and Series B Preferred stock of IPG
               currently outstanding (except for ratchet and warrants,
               participating rights after payment of full liquidation
               preference, and process control rights), including same
               liquidation preference and weighted average anti-dilution rights.
               The Series D Preferred would have no superior rights or
               preferences;

          iii. IPG would provide to JDSU copies of all financial materials
               submitted to its Board of Directors (e.g., balance sheets, income
               statements, cash flows), except for strategic marketing or
               product pricing materials. JDSU would agree to implement a
               "Chinese wall" within its organization to protect disclosure by
               the holder of the IPG materials to competing JDSU operating
               divisions and personnel; and

          iv.  This issuance would be subject to reasonable due diligence by
               JDSU and subject to reasonable confidentiality limitations on the
               material supplied to JDSU.

     B.   IPG would issue to JDSU the Convertible Note in the principal amount
          of $5,100,000, due three years after issuance and convertible, in
          whole or in part, at IPG's option, into Series D Preferred.

          i.   The conversion price for the Convertible Note into Series D
               Preferred would be $1.90 per share;

          ii.  The Series D Preferred shares acquired upon conversion of the
               Convertible Note would have a conversion price into common the
               same as the then conversion price for outstanding Series D
               Preferred shares (i.e., lower of $1.90/share or weighted average
               price (accounting for dilutive issuances, splits, reverse splits,
               etc.) of the outstanding Series D Preferred); and

          iii. The full amount of the Convertible Note would be immediately
               payable (or convertible) in the event of a Change in Control of
               IPG.

6.   Intellectual Property.

     A.   JDSU represents to its Knowledge (defined below) that no current
          product of JDSU violates any currently issued U.S. Patents owned by
          IPG for the design, manufacture or conception of fiber lasers or the
          components thereof. For purposes of this Settlement, "Knowledge" means
          the opinion of JDSU's Vice President of Intellectual Property, formed
          after due inquiry, including but not limited to the General Manager of
          JDSU's Commercial Lasers division.

     B.   IPG disclaims any and all rights, interests or ownership in and to any
          of the intellectual property used to develop or otherwise contained in
          the laser diodes and fiber laser products at issue in the Arbitration.
          IPG further agrees that JDSU's products have not violated IPG's fiber
          laser related patents; provided that this covenant does not affect any
          of IPG's rights or assets in the future, except as expressly stated in
          this Section 6 or in Sections 7B or 10B.

                                       6

<PAGE>

     C.   IPG covenants that it will not commence an action claiming that JDSU's
          or its Affiliates' products infringe any patents owned by IPG or its
          Affiliates, or which IPG or its Affiliates have the right to assert,
          for any period prior to the Closing. For purposes of this Settlement,
          "Affiliate" means an entity which owns or controls, directly or
          indirectly, more than 50% of the voting interests in, or more or than
          50% of the voting interests of which is owned or controlled, directly
          or indirectly, by a party.

     D.   IPG covenants that, for a period of three years from the date of the
          Closing, it will not bring any claims against JDSU or its Affiliates
          under any issued patents that exist as of the date of the Closing, or
          currently pending patent applications which IPG or its Affiliates own
          or have the right to assert. The covenant in the preceding sentence
          shall not prevent IPG from asserting patent infringement or
          intellectual property-related counterclaims or defenses against JDSU
          in a patent infringement lawsuit filed by JDSU against IPG, or for
          asserting misappropriation claims against JDSU directly related to the
          hiring or retention by JDSU of IPG's employees or consultants and the
          use by JDSU of information developed by such former IPG employee or
          consultant for or on behalf of IPG or others associated with IPG. In
          the event of any finding of liability against JDSU for patent
          infringement or violation of intellectual property rights of IPG, the
          parties agree to the following additional stipulations:

          i.   With respect to any existing JDSU fiber laser products, IPG
               foregoes recovery of any damages owed by JDSU to IPG for three
               years from the date of the Closing; and

          ii.  With respect to other JDSU products, IPG would be entitled to
               recover damages commencing not earlier than the date of the
               Closing.

     E.   Nothing in this Settlement shall be interpreted or construed as a
          grant, sale, transfer, assignment or license, directly or indirectly,
          by IPG or its Affiliates to JDSU of any intellectual property rights
          or properties, including without limitation any patent, copyright,
          trade secrets, trademarks or tradenames, of IPG or its Affiliates,
          whatsoever.

     D.   Possession of Claims.

          security interest in or lien upon, any Claim or portion thereof which

8.   California Civil Code Section 1542.

          The parties hereto acknowledge familiarity with Section 1542 of the
          Civil Code of the State of California, which provides as follows:

               A general release does not extend to claims which the creditor
               does not know or suspect to exist in his favor at the time of
               executing the release, which if known by him must have materially
               affected his settlement with the debtor.

     The parties hereto waive and relinquish any right and benefit which they
     have or may have under Section 1542 and any Massachusetts statutory or
     common law equivalent or any other similar applicable statutes to the full
     extent that they may lawfully waive all such rights and benefits pertaining
     to the subject matter of this Settlement as described above.

9.   Closing.

The consummation of the transactions and releases contemplated by this
Settlement shall occur at a closing (the "Closing"). It shall be a condition to
Closing that all of the Equity Documents shall be executed and delivered by the
parties hereto in form and substance reasonably satisfactory to both parties
hereto, and that all other documents or filings necessary or reasonably
requested by a party hereto to effectuate the Equity Document and the other
agreements set forth in this Settlement shall be executed and delivered and
shall have been made simultaneously. Subject to satisfaction of the conditions
in this Settlement, each party hereto shall deliver to the other party executed
originals of the Stipulation and Order of Dismissal-Arbitration; the Stipulation
and Order of Dismissal-State Court Action; the Note; the Security Agreement; the
Mortgage; the Master Supply Agreements; and the Equity Documents, including the
Convertible Note and a stock certificate representing the issued shares of
Series D Preferred. IPG shall also pay to JDSU at the Closing $302,006.30
referred to in Section 3(A) above. The covenants, representations and warranties
contained in Sections 6 (Intellectual Property), 7 (Worldwide Mutual Releases),
10 (Future Disputes), and 11 (Termination of Agreement) hereof shall become
effective only upon the consummation of the transactions contemplated by this
Settlement at the Closing.

10.  Future Disputes.

     A.   Attempts To Resolve.

          If, after the date of this Settlement, either IPG or JDSU (the
          "Alleging Party") believes it has a claim (a "New Dispute") against
          the other, the Alleging Party shall give notice to the other party of
          the New Dispute, setting forth, in reasonable detail, the nature and
          basis for the New Dispute. The parties, for a period of thirty (30)
          days (or such other longer period as determined by mutual consent of
          the Disputing Parties), shall use their best efforts to resolve such
          New Dispute between themselves and neither party shall commence any
          such action during such thirty (30) day period.

     B.   IPG's Assertion of Defenses.

          In the event JDSU brings an action against IPG for breach of any term
          or obligation of this Settlement and the other instruments and
          documents to be entered into by it pursuant hereto, IPG agrees that it
          will not assert as a counterclaim or defense in that action, any
          claims contending that JDSU has engaged in unfair competition or other
          claims brought under the anti-trust laws of the United States, any of
          its

                                       9

<PAGE>

          states, or a foreign country. To the extent that IPG wishes to pursue
          any of the foregoing claims against JDSU, IPG shall be permitted to
          assert those claims in a separate and unrelated action but only to the
          extent that the basis for the claim is not JDSU's assertion of a
          breach of any term or obligation of this Settlement and the other
          instruments and documents to be entered into by it pursuant hereto.

11.  Termination of Agreement.

     Upon execution of this Settlement, the Agreement between IPG and JDSU shall
terminate and neither party shall have any further rights or obligations
thereunder.

12.  Confidentiality.

relations advisor, insurance carrier or other consultant is bound, subject to
the requirements of applicable law, to confidentiality, (C) any party may
disclose the existence and the terms of this Settlement if and to the extent
(but only to the extent) it is required to do so by an order of a court of
competent jurisdiction or by a subpoena or any other demand for discovery made
in an action or proceeding pending in a court or governmental agency of
competent jurisdiction, provided that, in the case of such a subpoena or other
demand for discovery, the party receiving such process shall notify each other
party to this Settlement of such receipt, together with delivery of a copy
thereof and, in such case, any such notified party shall have the right to
object, at its own cost, to compliance with any such subpoena or other demand
based on the confidentiality of this Settlement.

13.  Further Cooperation.

     The parties hereto agree to execute and deliver any and all additional
papers, documents and other assurances and shall do any and all acts or things
reasonably necessary in connection with the performance of their obligations
hereunder to implement the provisions of this Settlement.

14.  Costs and Fees.

     Each party shall bear its own attorneys' fees and costs incurred in
connection with the Arbitration and State Court Action, and with respect to the
negotiation, execution and delivery of this Settlement and each document
required to be delivered hereunder.

     only and do not constitute a Section of this Settlement. The use of the
