                               NON-QUALIFIED STOCK
                   OPTION AGREEMENT TERMS AND CONDITIONS UNDER
           IPG PHOTONICS CORPORATION 2006 INCENTIVE COMPENSATION PLAN

1. Definitions; Section References. All terms used in this Agreement that are
not otherwise defined shall have the meanings ascribed to them in the IPG
Photonics Corporation 2006 Incentive Compensation Plan, as amended from time to
time (the "Plan") or the Option Agreement ("Option Agreement") executed by the
Optionee and IPG Photonics Corporation, a Delaware corporation (the "Company").
Unless otherwise indicated, all section references are to sections of this
Agreement. If the Notice states that the Option is an Incentive Stock Option,
then the Option is intended to be incentive stock options within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended, and subject to the
limitations and treatment thereof.

2. Term and Exercise of Option Shares. The term and exercise of the Option shall
be as follows:

(a) The term of the Option granted shall commence as of Grant Date and shall end
on the Expiration Date, unless earlier terminated in accordance with Section 5.
No option may be exercised after the Expiration Date.

(b) The Option shall only be exercised to the extent the Option has Vested and
has not been previously exercised. The Option granted shall be exercised by the
Optionee by delivering the following to the Secretary of the Company or to any
other person as may be designated by the Company from time to time, on any
business day prior to or on the Expiration Date:

(1)  A signed Notice of Exercise of Stock Option in the form prescribed by the
     Company from time to time specifying the number of Shares the Optionee
     desires to purchase;

(ii) A signed Stock Option Purchase Agreement in the form prescribed by the
     Company from time to time (The Notice of Exercise of Stock Option and Stock
     Purchase Agreement attached are available from the Secretary of the
     Company);

(iii) Payment in full of the purchase price, subject to the requirements of
     Section 4; and such other documents or agreements requested by the
     Secretary or the Committee.

(c) For the first six months following an IPO of the Company, Optionee agrees
that Optionee may not sell, exchange, transfer, or otherwise dispose of any
Shares acquired upon exercise of the Option without the consent of the Company,
which consent may be withheld in the Company's absolute and sole discretion.

4. Exercise Price.

(a) The price per Share at which the Option shall be exercisable shall be the
Exercise Price as defined in the Notice.

(b) The exercise price of the Shares subject to this Agreement may be paid by
(i) certified or bank check; (ii) the tender of unrestricted Shares already
owned by the Optionee; or (iii) such other means the Committee determines are
consistent with the purpose of the Award and applicable law.

(c) The Optionee may satisfy the applicable withholding tax obligations by
paying the amount of any taxes in cash within thirty (30) days of the date of
exercise. Shares or other securities of the Company may, subject to compliance
with Section 16 of the Securities Exchange Act of 1934 and the rules promulgated
thereunder, if applicable, be delivered to the Company or deducted from the
number of Shares to be delivered to the Optionee to satisfy the obligation in
full or in part as long as such withholding of Shares does not violate any
applicable laws, rules, or regulations of federal, state, or local authorities.
The number of Shares or other securities of the Company to be deducted shall be
determined by reference to the Fair Market Value of such Shares or Fair Market
Value of such other securities as determined by the Committee on the applicable
date.

5. Termination of Option.

(a) Death, Disability or Retirement. In the event of termination of the
Optionee's employment due to Disability or Retirement, this Option may
thereafter be exercised by the Optionee within ninety (90) days following the
date of Disability or Retirement, to the extent it was exercisable at the time
such event occurred. The Committee may at any time and in its sole discretion
accelerate the exercisability of this Option. Upon the death of an Optionee,
Options shall be exercisable for a period of twelve (12) months from the date of
death or until the Expiration Date.

  BY SIGNING THE OPTION AGREEMENT, YOU AGREE TO THESE TERMS & CONDITIONS. READ
                                 THEM CAREFULLY.

<PAGE>

(b) Separation from Service for Cause. If Optionee's employment by the Company,
an Affiliate or Group Company or other service provider relationship with the
Company, an Affiliate or Group Company terminates involuntarily for Cause, any
unexercised Option held by Optionee and not in fact exercised prior to
termination shall immediately expire and all rights under such Option shall
immediately be forfeited.

(c) Other Terminations of Employment. If the Optionee's employment is terminated
for any reason other than for Cause or other than due to death, Disability or
Retirement:

(i)  all non-Vested portions of Options held by the Optionee on the date of the
     termination of his or her employment shall immediately be forfeited by the
     Optionee as of such date; and

(ii) all Vested portions of Options held by the Optionee on the date of the
     termination of his or her employment shall remain exercisable until the
     earlier of (i) the end of the 90-day period following the date of the
     termination of the Optionee's employment or (ii) the date the Options would
     otherwise expire.

6. Rights as a Stockholder; Effect of Option. The Optionee shall have no rights
as a stockholder of the Company with respect to any Shares covered by this
Option until the issuance of a stock certificate for those Shares. Once this
Option or any portion thereof is exercised and Shares are transferred to the
Optionee, any shareholder agreements that apply to the Shares shall be binding
on the Optionee. This Option shall not be deemed to confer upon the Optionee any
rights to continue in the employ of the Company, an Affiliate or Group Company.
Neither the Optionee nor his or her transferee is or will be obligated by the
grant of the Option to exercise it.

7. Changes in Capitalization.

(a) The grant of an Option pursuant to this Agreement shall not affect in any
way the right or power of the Company to make adjustments, reclassifications,
reorganizations, or changes of its capital or business structure or to merge or
to consolidate or to dissolve, liquidate or sell, or transfer all or any part of
its business or assets.

(b) If, while this Option is outstanding, the outstanding Shares have increased,
decreased, changed into, or been exchanged for a different number or kind of
shares or securities of the Company through reorganization, merger,
recapitalization, reclassification, stock split, reverse stock split, stock
dividend, or similar transaction, appropriate and proportionate adjustments
shall be made by the Committee to the number and/or kind of Shares which are
subject to purchase under this Option and for the Option exercise price or
prices applicable to this Option. Such adjustments will be made so that the same
proportion of the Company's issued and outstanding Shares in each instance shall
remain subject to purchase at the same aggregate exercise price.

(c) In the event of a change in the Shares of the Company as presently
constituted, which is limited to a change of all its authorized shares with par
value into the same number of shares with a different par value or without par
value, the Shares resulting from any such change shall be deemed to be Shares
within the meaning of this Agreement.

(d) In the event of a merger, consolidation, or acquisition of substantially all
of the Company's Shares or assets, the Committee may take such actions with
respect to outstanding Options as the Committee deems appropriate.

(e) If any fractional share would result from any such adjustment under this
Section 7, the Company shall not issue such fractional share, but shall round
any portion of a share equal to .500 or greater up, and any portion of a share
equal to less than .500 down, in each case to the nearest whole number.

8. Nondisclosure, Noncompete, and Nonsolicit.

(a) Nondisclosure and Nonuse of Confidential Information. Optionee agrees that
Optionee will not at any time, whether during or after the Optionee's Service,
use or reveal to anyone outside the Company any of the trade secrets or
confidential information of the Company, its customers or suppliers, or any
information received in confidence from third parties by the Company, except to
the extent that such disclosure or use is directly related to and required by
Optionee's performance of duties assigned to the Optionee by the Company, an
Affiliate or Group Company. Confidential Information of the Company is any
information or material (a) generated or collected by or used in the operation
of the Company, an Affiliate or Group Company that relates to the actual or
anticipated business, marketing and sales, strategic planning, products,
services, research and development, or production and/or manufacturing
processes, of the Company, an Affiliate or Group Company or its customers or
suppliers, including its and

their organization, personnel, customers and finances; or (b) suggested by or
resulting from any task assigned to Optionee or work performed by Optionee for
or on behalf of the Company, an Affiliate or Group Company not otherwise readily
available to members of the general public.

(b) Forfeiture for Competition. Optionee acknowledges and agrees that (i) in the
course of the Optionee's Service, Optionee shall become familiar with the trade
secrets of the Company, its Affiliates and Group Companies and with other
Confidential Information concerning the Company, its Affiliates and Group
Companies, (ii) Optionee's Services to the Company, its Affiliates and Group
Companies are unique in nature and of an extraordinary value to the Company, its
Affiliates and Group Companies, and (iii) the Company, its Affiliates and Group
Companies could be irreparably damaged if Optionee were to provide similar
services to any person or entity competing with the Company, an Affiliate or
Group Company or engaged in a similar business. In connection with the issuance
to Optionee of the Option hereunder, and in consideration for and as an
inducement to the Company to enter into this Agreement, the Optionee covenants
and agrees that during the period beginning on the Grant Date and ending on the
first anniversary of the date of the termination of the Optionee's Service, the
Optionee shall not, directly or indirectly, either for himself or for or through
any other Person, without the express written consent of the Company, anywhere
in the world, engage in any activity that is, or participate or invest in, or
provide or facilitate the provision of financing to, or assist (whether as
owner, part-owner, shareholder, member, partner, director, officer, trustee,
employee, agent or consultant, or in any other capacity) any business,
organization or Person other than the Company (or any subsidiary of the
Company), and including any such business, organization or person involving, or
which is, a family member of Optionee, whose business, activities, products or
services are competitive with the products, technologies or services offered or
proposed to be offered by the Company, an Affiliate or Group Company. The
Optionee agrees that this covenant is reasonable with respect to its duration,
geographical area and scope. For purposes of this Agreement, the term
"participate in" includes having any direct or indirect interest in any Person,
whether as a sole proprietor, owner, shareholder, partner, joint venture,
creditor or otherwise, or rendering any direct or indirect service or assistance
to any Person (whether as a director, officer, manager, supervisor, employee,
agent, consultant or otherwise), other than owning up to 3% of the outstanding
stock of any class that is publicly traded.

(c) Nonsolicitation. Optionee hereby agrees that during the period commencing on
the Grant Date and ending on the date which is the later to occur of (i) two (2)
years after the Grant Date and (ii) eighteen (18) months after the date of the
termination of Optionee's Service, the Optionee will not, without the express
written consent of the Company, (w) induce or attempt to induce for or on behalf
of himself or herself or any such competitor any officer, employee or former
employee of the Company, its Affiliates or Group Companies, who was employed
during the one (1) year period immediately preceding the date on which
Optionee's Service with the Company, an Affiliate or Group Company was
terminated for any reason, (x) encourage for or on behalf of himself or any such
competitor any such officer or employee to terminate his or her Service to the
Company, an Affiliate or Group Company, (y) solicit for or on behalf of himself
or any such competitor any client or supplier of the Company, an Affiliate or
Group Company, or (z) divert to any Person any client or business opportunity of
the Company, an Affiliate or Group Company.

(d) Judicial Modification. If the final judgment of a court of competent
jurisdiction declares that any term or provision of this Section 8 is invalid or
unenforceable, the parties agree that (i) the court making the determination of
invalidity or unenforceability shall have the power to reduce the scope,
duration, or geographic area of the term or provision, to delete specific words
or phrases, or to replace any invalid or unenforceable term or provision with a
term or provision that is valid and enforceable and that comes closest to
expressing the intention of the invalid or unenforceable term or provision, (ii)
the parties shall request that the court exercise that power, and (iii) this
Agreement shall be enforceable as so modified after the expiration of the time
within which the judgment or decision may be appealed.

(e) Remedy for Breach. The Optionee agrees that in the event of a breach or
threatened breach of any of the covenants contained in this Section 8, in
addition to any other penalties or restrictions that may apply under any
employment agreement, state law, or otherwise, the Optionee shall forfeit:

(i) any and all Options granted or transferred to him or her under the Plan and
this Agreement, including vested Options; and

(ii) the profit the Optionee has realized on the exercise of any Options, which
is the difference between the Exercise Price of the Options and the applicable
Fair Market Value of the Shares (the Optionee may be required to repay such
difference to the Company).

  BY SIGNING THE OPTION AGREEMENT, YOU AGREE TO THESE TERMS & CONDITIONS. READ

Optionee to furnish to the Company, prior to the issuance of any Shares upon the

connection with the Shares then to be issued, the issue of the Shares shall be
deferred until the action shall have been taken; however, the Company shall have
no liability whatsoever as a result of the non-issuance of the Shares, except to
refund to the Optionee any consideration tendered in respect of the exercise
price.

parties. Any successors to the parties to this Agreement shall be entitled to
all of the rights of and obligated to abide by all provisions of any shareholder
agreements that apply to the Shares held by such successors.

14. Severability. In the event that any one or more of the provisions or portion
thereof contained in this Agreement shall for any reason be held to be invalid,
illegal, or unenforceable in any respect, the same shall not invalidate or
otherwise affect any other provisions of this Agreement and this Agreement shall
be construed as if the invalid, illegal, or unenforceable provision or portion
thereof had never been contained herein.

15. Entire Agreement. This Agreement, the Notice and the Plan constitute and
contain the entire Agreement and understanding between the parties with respect

nor this Agreement is a contract of employment or Service, and no terms of the
Optionee's employment or Service will be affected in any way by the Plan, this
Agreement or related instruments, except to the extent specifically expressed
therein. Neither the Plan nor this Agreement will be construed as conferring any
legal rights of the Optionee to continue to be employed or remain in Service
with the Company, nor will it interfere with the right of the Company, an
Affiliate or Group Company to discharge the Optionee or to deal with him or her
regardless of the existence of the Plan, this Agreement or the Option.
