                              Employment Agreement

This Employment Agreement ("Agreement"), dated as of March 1, 2006, is made by
and between IPG Photonics Corporation, a Delaware corporation having an office
at 50 Old Webster Road, Oxford, MA, 01540 (the "Corporation"), and Denis
Gapontsev ("Executive"). The Corporation and Executive are referred to jointly
below as the "Parties."

WHEREAS, the Corporation desires to employ Executive on the terms and conditions
set forth in this Agreement; and

WHEREAS, Executive desires to accept employment by the Corporation on such terms
and conditions.

NOW, THEREFORE, in consideration of the employment of Executive, the mutual
terms and conditions set forth below, and other good and valuable consideration,
the receipt and sufficiency of which is hereby acknowledged, the Parties agree
as follows:

     1. Employment. Executive will be employed by the Corporation in the
position of Vice President - Research and Development. Executive will report to
the Corporation's Chief Executive Officer. Executive's primary responsibility
will be managing the laser and amplifier research staff at the Corporation's US
operation, sales and marketing of the Corporation's products (other than telecom
products) research and development. Executive will carry out such duties as
shall be assigned from time to time by the Corporation's Chief Executive
Officer, subject to applicable laws, and ethical duties. During the Employment
Term (as defined below), Executive shall devote Executive's reasonable best
efforts, energies and abilities and Executive's full business time, skill and
attention to the business and affairs of the Corporation, and shall act at all
times according to the highest professional standards, for the purpose of
advancing the business of the Corporation.

     2. Term. Subject to the Termination provisions below, Executive's
employment by the Corporation is for a term of two (2) years commencing on the
date of this Agreement (the "Initial Employment Period"). Executive's employment
by the Corporation will continue for successive one year terms following
expiration of the Initial Employment Period (the Initial Employment Period
together with any subsequent employment period shall be referred to as the
"Employment Term"), unless either party provides notice of intent not to renew
not less than (a) one hundred eighty (180) days prior to expiration of the then
current term or (b) 364 days prior to the end of the then current term following
a "Change of Control" of the Corporation (as such term is defined in the
Corporation's 2006 Incentive Stock Plan in effect on the date of this
Agreement), or unless in either case employment is terminated under the
termination provisions below.

     3. Compensation. The Corporation shall pay Executive on a salary basis at
an annual rate of $240,000 (the "Base Salary"). The Base Salary will be paid in
equal installments in accordance with the Corporation's standard payroll
policies and schedule and is subject to tax and elective withholding and
deductions. The Corporation may, in its sole discretion, increase the Base
Salary on an annual or other basis. The amount of any bonus compensation to
Executive under any such program will be determined by the Board of Directors in
its sole discretion.

     4. Benefits.

          (i) Executive shall be entitled to the extent eligible to participate
in any benefit plans as may be adopted and modified by the Corporation from time
to time, including without limitation health, dental and medical plans, life and
disability insurance, paid time off, holiday, and retirement plans. The benefits
available to Executive shall be no less favorable than those available to other
executives at similar levels within the organization or to the employees of the
Company at the location where Executive works. Benefits provided under this
Agreement shall be subject to the terms and conditions of any applicable benefit
plan, including any eligibility and vesting requirements, as such plans may be
in effect from time to time.

          (ii) Executive shall be entitled to four weeks vacation each year. The

time is equal to the total vacation hours earned in the last twelve months, plus
one week of vacation carried over from the prior twelve months of service.

     5. Intentionally Omitted.

     6. Other Activities. The employment of Executive shall be on a full-time
basis, but Executive may be an investor or otherwise have an interest in or
serve on the board of directors or advisory board to other businesses,
partnerships and entities so long as the other activities of Executive do not
materially interfere with the performance of Executive's duties to the
Corporation, and so long as such other activities do not cause Executive to
violate the Restrictive Covenants incorporated herein in Section 12 of this
Agreement, and so long as Executive discloses all such activities to the Chief
Executive Officer and the Board of Directors of the Corporation. Nothing in this
provision or this Agreement limits or restricts Executive's duties and
obligations, including the duty of loyalty, that arise under the law.

     7. Termination by the Corporation. The Corporation may terminate the
Employment Term:

          (i) by giving Executive ninety (90) days' prior written notice without
Cause (as defined below), or

          (ii) for Cause (as defined below).

"Cause" shall mean: (A) an act of fraud, embezzlement or theft by Executive in
connection with Executive's duties or in the course of Executive's employment
with the Corporation; (B) Executive's intentional wrongful damage to the
property of the Corporation; (C) Executive's intentional breach of Section 12
hereof while Executive remains in the employ of the Corporation; (D) an act of
Gross Misconduct (as defined below); or (E) a felony conviction or a conviction
for a misdemeanor involving moral turpitude; and, in each case, the
determination by the Directors of the Corporation as hereafter provided that any
such act shall have been materially harmful to the Corporation. For purposes of
this Agreement, "Gross Misconduct" shall mean a willful or grossly negligent act
or omission which has or will have a material and adverse impact on the business
or reputation of the Corporation, or on the business of the Corporation's
customers or suppliers as such relate to the Corporation. Notwithstanding the
foregoing, Executive shall not be deemed to have been terminated for "Cause"
hereunder unless and until there

                                        2

<PAGE>

shall have been delivered to Executive a copy of a resolution duly adopted by
the affirmative vote of a majority of the independent Directors then in office
at a meeting of the Directors called and held for such purpose, finding that,
Executive has committed an act set forth above in this Section 7. Nothing herein
shall limit Executive's right or Executive's beneficiaries' right to contest the
validity or propriety of any such determination.

     8. Termination by Executive. Executive may terminate the Employment Term
(i) by giving the Corporation sixty (60) days' prior written notice, or (ii) for
Good Reason (as defined below), subject to the Corporation's right to cure the
breach for a period of thirty (30) days after notice from Executive of his
intention to terminate for Good Reason. In the event of termination by notice
under the preceding subsection (i), the Corporation in its discretion may elect
a termination date that is earlier than the conclusion of the sixty (60) day
notice period, but in the event of such election the termination shall still be
deemed a voluntary termination by Executive under this Section. "Good Reason"
means the occurrence of any of the following events without Executive's express
written consent:

               (a)  The assignment to Executive of any duties materially
                    inconsistent (except in the nature of a promotion) with
                    Executive's position in the Corporation and the
                    responsibilities specified in this Agreement or a
                    substantial adverse alteration in the nature of Executive's
                    position or responsibilities or in the conditions of
                    employment;

               (b)  A reduction by the Corporation of or a failure to pay
                    Executive's Base Salary, or a material reduction in benefits
                    Executive is entitled to under this Agreement other than a
                    reduction approved by the Board of Directors of the
                    Corporation that similarly applies to all executive officers
                    of the Company, provided that a reduction in Base Salary
                    shall not exceed more than 10% of then Base Salary;

               (c)  A relocation of the offices of Executive to a place greater
                    than thirty-five (35) miles in distance from Executive
                    offices of the Corporation in Oxford, MA; or

               (d)  The failure of Executive to be the Vice President - Research
                    and Development of (i) a company having its securities
                    registered under the Securities Exchange Act of 1934
                    following the effectiveness of the Corporation's initial
                    public offering, or (ii) the Corporation following a "Change
                    of Control" of the Corporation (as such term is defined in
                    the Corporation's 2006 Incentive Stock Plan in effect on the
                    date of this Agreement).

     12. Restrictive Covenants. Executive has executed and delivered a
Confidentiality, Non-Competition and Confirmatory Assignment Agreement, dated
the date hereof (the "Restrictive Covenants") and Executive agrees that, as part
of this Agreement, Executive shall comply with the terms of the Restrictive
Covenants.

     13. Indemnification.

          (i) Indemnification Terms. The Corporation agrees that if Executive is
made a party, or is threatened to be made a party, to any action, suit or
proceeding, whether civil, criminal, administrative or investigative (a
"Proceeding"), by reason of the fact that he is or was a director, officer or
employee of the Corporation or is or was serving at the request of the
Corporation as a director, officer, member, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, including
service with respect to employee benefit plans, whether or not the basis of such
Proceeding is Executive's alleged action in an official capacity while serving
as a director, officer, member, employee or agent, Executive shall be
indemnified and held harmless by the Corporation to the fullest extent permitted
or authorized by the Corporation's certificate of incorporation or bylaws or, if
greater, by the laws of the State of Massachusetts, against all cost, expense,
liability and loss (including, without limitation, attorney's fees, judgments,
fines, ERISA excise taxes or penalties and amounts paid or to be paid in
settlement) reasonably incurred or suffered by Executive in connection
therewith, and such indemnification shall continue as to Executive even if he
has ceased to be a director, member, employee or agent of the Corporation or
other entity and shall inure to the benefit of Executive's heirs, executors and
administrators. The Corporation shall advance to Executive all reasonable costs
and expenses incurred by him in connection with a Proceeding within 20 days
after receipt by the Corporation of a written request for such advance. Such
request shall include an undertaking by Executive to repay the amount of such
advance if it shall ultimately be determined that he is not entitled to be
indemnified against such costs and expenses.

          (ii) No Presumptions. Neither the failure of the Corporation
(including its Board, independent legal counsel or stockholders) to have made a
determination prior to the commencement of any proceeding concerning payment of
amounts claimed by Executive under Section 15(a) above that indemnification of
Executive is proper because he has met the applicable standard of conduct, nor a
determination by the Corporation (including its Board, independent legal counsel
or stockholders) that Executive has not met such applicable standard of conduct,
shall create a presumption that Executive has not met the applicable standard of
conduct.

          (iii) Liability Insurance. The Corporation agrees to continue and
maintain a directors' and officers' liability insurance policy covering
Executive to the extent the Corporation provides such coverage for its other
executive officers, and which would provide coverage for Executive after the
Term of Employment for actions taken during the Term of Employment.

and shall be delivered by certified mail, return receipt requested or in person.
Notice shall be deemed to have been given when notice is received by the party
on whom the notice was served. Notice to the Corporation shall be addressed to

                                        5

     15. Governing Law. This Agreement shall be governed by, construed and
enforced in accordance with the substantive laws of the Commonwealth of
Massachusetts, without regard to its internal conflicts of law provisions.

be determined to be invalid, illegal or otherwise unenforceable or contrary to
law or public policy, the enforceability of the other provisions in this
Agreement shall not affected thereby.

     17. Assignment. Executive recognizes that this is an agreement for personal
services and that Executive may not assign this Agreement. The Agreement shall

assigns.

other agreements, either oral or in writing, among the Parties hereto with
respect to the subject matter hereof. This Agreement may not be amended except
by written agreement signed by both Parties.

     19. Execution in Counterparts. This Agreement may be executed in one or
more counterparts, and by the different Parties in separate counterparts, each

constitute one and the same agreement (and all signatures need not appear on any
one counterpart), and this Agreement shall become effective when one or more
counterparts has been signed by each of the Parties hereto and delivered to each
of the other Parties hereto.

     20. Waiver. The failure of either of the Parties to at any time enforce any
of the provisions of this Agreement shall not be deemed or construed to be a
waiver of any such provision, nor to in any way affect the validity of this
Agreement or any provision hereof or the right of either of the Parties to
enforce each and every provision of this Agreement. No waiver of any breach of
any of the provisions of this Agreement shall be effective unless set forth in a
written instrument executed by the party against whom or which enforcement of
such waiver is sought, and no waiver of any such breach shall be construed or
deemed to be a waiver of any other or subsequent breach.

     21. Capacity. Executive and the Corporation hereby represent and warrant to
the other that: (i) Executive or the Corporation has full power, authority and
capacity to execute and deliver this Agreement, and to perform Executive's or
the Corporation's obligations hereunder; (ii) such execution, delivery and

Executive or the Corporation is a party or Executive or the Corporation is
otherwise bound; and (iii) this Agreement is Executive's or the Corporation's
valid and binding obligation in accordance with its terms.

     22. Arbitration. Any controversy or claim arising out of or relating to
this Agreement or the breach thereof or otherwise arising out of Executive's
employment or the termination of that employment (including, without limitation,
any claims of unlawful employment discrimination whether

the absence of such an agreement, under the auspices of the American Arbitration
Association ("AAA") in Worcester, Massachusetts in accordance with the
Employment Dispute Resolution Rules of the AAA, including, but not limited to,
the rules and procedures applicable to the selection of arbitrators. In the
event that any person or entity other than Executive or the Employer may be a
party with regard to any such controversy or claim, such controversy or claim
shall be submitted to arbitration subject to such other person or entity's
agreement. Judgment upon the award rendered by the arbitrator may be entered in
any court having jurisdiction thereof. This Section 23 shall be specifically
enforceable. Notwithstanding the foregoing, this Section 23 shall not preclude
either party from pursuing a court action for the sole purpose of obtaining a
temporary restraining order or a preliminary injunction in circumstances in
which such relief is appropriate; provided that any other relief shall be
pursued through an arbitration proceeding pursuant to this Section 23. Punitive
and consequential damages shall not be permitted as an award and each party
shall bear the fees and expenses of its own counsel and expert witnesses.

     23. Consent to Jurisdiction. To the extent that any court action is
permitted consistent with or to enforce Section 23 of this Agreement, the
parties hereby consent to the jurisdiction of the Superior Court of the
Commonwealth of Massachusetts and the United States District Court for the
District of Massachusetts. Accordingly, with respect to any such court action,
Executive (a) submits to the personal jurisdiction of such courts; (b) consents
to service of process; and (c) waives any other requirement (whether imposed by
statute, rule of court, or otherwise) with respect to personal jurisdiction or
service of process.

IN WITNESS WHEREOF, this Employment Agreement has been duly executed:

     This Indemnification Agreement (this "Agreement") is made this __ day of
_______, 2006, between IPG Photonics Corporation, a Delaware corporation (the
"Company"), and _______________________ ("Indemnitee").

     WHEREAS, it is essential to the Company that it be able to retain and
attract as directors and officers the most capable persons available;

     WHEREAS, increased corporate litigation has subjected directors and
officers to litigation risks and expenses, and the limitations on the
availability of directors and officers liability insurance have made it

     WHEREAS, the Amended and Restated By-laws of the Company (the "By-laws")
provide for the indemnification of its directors and officers and permit it to
make other indemnification arrangements and agreements;

     WHEREAS, the Company desires to provide Indemnitee with specific

     WHEREAS, this Agreement is a supplement to and in furtherance of the
Amended and Restated Certificate of Incorporation of the Company (the
"Certificate") and the By-laws and any resolutions adopted pursuant thereto, and
shall not be deemed a substitute therefor, nor to diminish or abrogate any
rights of Indemnitee thereunder;

     WHEREAS, Indemnitee does not regard the protection available under the
Company's By-laws and insurance as adequate in the present circumstances, and
may not be willing to serve as director or officer without adequate protection,
and the Company desires Indemnitee to serve in such capacity. Indemnitee is
willing to serve, continue to serve and to take on additional service for or on
behalf of the Company on the condition that he be so indemnified; and

     WHEREAS, Indemnitee is relying upon the rights afforded to the Indemnitee
under this Agreement in [accepting] [continuing in] Indemnitee's position as a

advisors (including, without limitation, accountants and investment bankers),
court costs, transcript costs, fees of experts, travel expenses, duplicating,
printing and binding costs, telephone and fax transmission charges, postage,
delivery services, secretarial services and other disbursements and expenses.

          (g) "Independent Counsel" means a law firm, or a member of a law firm,
that is experienced in matters of corporation law and neither presently is, nor
in the past five (5) years has been, retained to represent: (i) the Company or
Indemnitee in any matter material to either such party (other than with respect
to matters concerning the Indemnitee under this Agreement, or of other
indemnitees under similar indemnification agreements), or (ii) any other party
to the Proceeding (as defined below) giving rise to a claim for indemnification
hereunder. Notwithstanding the foregoing, the term "Independent Counsel" shall
not include any person who, under the applicable standards of professional
conduct then prevailing, would have a conflict of interest in representing
either the Company or Indemnitee in an action to determine Indemnitee's rights
under this Agreement. The Company agrees to pay the reasonable fees and expenses
of the Independent Counsel referred to above and to fully indemnify such counsel
against any and all Expenses,

                                        3

<PAGE>

claims, liabilities and damages arising out of or relating to this Agreement or
its engagement pursuant hereto.

          (h) "Liabilities" means judgments, damages, liabilities, obligations,
losses, penalties, excise taxes, fines and amounts paid in settlement.

          (i) "Proceeding" means any threatened, pending or completed claim,
action, suit, arbitration, alternate dispute resolution process, investigation,
administrative hearing, appeal or any other proceeding, whether civil, criminal,
administrative, arbitrative or investigative, whether formal or informal,
including a proceeding initiated by Indemnitee pursuant to Section 12 of this
Agreement to enforce Indemnitee's rights hereunder.

          (j) "Subsidiary" means any Entity of which the Company owns (either
directly or through or together with another Subsidiary of the Company) either
(i) a general partner, managing member or other similar interest or (ii) 50% or
more of the outstanding voting capital stock or other voting equity interests of
such Entity.

     2. Services of Indemnitee. In consideration of the Company's undertakings
in this Agreement, Indemnitee agrees to serve or continue to serve as a director
and/or officer of the Company. However, this Agreement does not impose any
obligation on Indemnitee or the Company to continue Indemnitee's service to the
Company beyond any period otherwise required by law or by other agreements
between the Company and Indemnitee, if any.

     3. Agreement to Indemnify. The Company shall indemnify Indemnitee as
follows:

          (a) Subject to the exceptions contained in Section 4(a) below, if
Indemnitee was or is a party, or is threatened to be made a party, to any
Proceeding (other than an action by or in the right of the Company) by reason of
Indemnitee's Corporate Status, the Company shall, to the extent permitted by
applicable law, indemnify Indemnitee against all Expenses and Liabilities
incurred or paid by Indemnitee in connection with such Proceeding (referred to
herein as "Indemnifiable Expenses" and "Indemnifiable Liabilities,"
respectively, and collectively as "Indemnifiable Amounts").

          (b) To the extent permitted by applicable law and subject to the
exceptions contained in Section 4(b) below, if Indemnitee was or is a party, or
is threatened to be made a party, to any Proceeding by or in the right of the
Company to procure a judgment in its favor by reason of Indemnitee's Corporate
Status, the Company shall indemnify Indemnitee against all Indemnifiable
Expenses.

     4. Exceptions to Indemnification. The Company shall indemnify Indemnitee
under Sections 3(a) and 3(b) above in all circumstances other than the
following:

          (a) If indemnification is requested under Section 3(a) and it has been
finally adjudicated by a court of competent jurisdiction (or arbitrator in an
arbitration proceeding commenced by Indemnitee in accordance with Section 12
hereof) that, (i) in connection with the subject of the

                                        4

<PAGE>

Proceeding out of which the claim for indemnification has arisen, Indemnitee
failed to act in good faith and in a manner Indemnitee reasonably believed to be
in, or not opposed to, the best interests of the Company, or (ii) with respect
to any criminal action or proceeding, Indemnitee had reasonable cause to believe
that Indemnitee's conduct was unlawful, then any such case, Indemnitee will not
be entitled to payment of Indemnifiable Amounts hereunder.

          (b) If indemnification is requested under Section 3(b) and:

               (i) it has been finally adjudicated by a court of competent
     jurisdiction (or arbitrator in an arbitration proceeding commenced by
     Indemnitee in accordance with Section 12 hereof) that, in connection with
     the subject of the Proceeding out of which the claim for indemnification
     has arisen, Indemnitee failed to act in good faith and in a manner
     Indemnitee reasonably believed to be in, or not opposed to, the best
     interests of the Company, then Indemnitee will not be entitled to payment
     of Indemnifiable Expenses hereunder; or

               (ii) it has been finally adjudicated by a court of competent
     jurisdiction (or arbitrator in an arbitration proceeding commenced by
     Indemnitee in accordance with Section 12 hereof) that Indemnitee is liable
     to the Company with respect to any claim, issue or matter involved in the
     Proceeding out of which the claim for indemnification has arisen,
     including, without limitation, a claim that Indemnitee received an improper
     personal benefit, then no Indemnifiable Expenses will be paid with respect
     to such claim, issue or matter unless the court in which such Proceeding
     was brought determines upon application that, despite the adjudication of
     liability, in view of all the circumstances of the case, Indemnitee is
     fairly and reasonably entitled to such Indemnifiable Expenses as such court
     deems proper.

          (c) Notwithstanding any provision in this Agreement, the Company shall
not be obligated under this Agreement to make any indemnity in connection with
any claim made against Indemnitee:

               (i) for which payment has actually been made to or on behalf of
     Indemnitee under any insurance policy or other indemnity provision, except
     with respect to any excess beyond the amount paid under any insurance
     policy or other indemnity provision; or

               (ii) for (i) an accounting of profits made from the purchase and
     sale (or sale and purchase) by Indemnitee of securities of the Company
     within the meaning of Section 16(b) of the Exchange Act or similar
     provisions of state statutory law or common law, or (ii) any reimbursement
     of the Company by the Indemnitee of any bonus or other incentive-based or
     equity-based compensation or of any profits realized by the Indemnitee from
     the sale of securities of the Company, as required in each case under the
     Exchange Act; or

               (iii) except as provided in Sections 12(d) and 22 of this
     Agreement, in connection with any Proceeding (or any part of any
     Proceeding) initiated by Indemnitee, including any Proceeding (or any part
     of any Proceeding) initiated by Indemnitee against the Company or its
     directors, officers, employees or other indemnitees, unless (i) the

                                        5

<PAGE>

     board of directors of the Company authorized the Proceeding (or any part of
     any Proceeding) prior to its initiation or (ii) the Company provides the
     indemnification, in its sole discretion, pursuant to the powers vested in
     the Company under applicable law.

     5. Procedure for Payment of Indemnifiable Amounts. Indemnitee shall submit
to the Company a written request specifying the Indemnifiable Amounts for which
Indemnitee seeks payment under Section 3 of this Agreement and the basis for the
request. The Company shall pay such Indemnifiable Amounts to Indemnitee within
fifteen (15) days of receipt of the request. At the request of the Company,
Indemnitee shall furnish such documentation and information as is reasonably
available to Indemnitee and necessary to establish that Indemnitee is entitled
to indemnification hereunder.

     6. Indemnification for Expenses of a Witness. Notwithstanding any other
provision of this Agreement, if Indemnitee is, by reason of Indemnitee's
Corporate Status, a witness in any Proceeding to which Indemnitee is not a
party, the Company shall indemnify Indemnitee against all Expenses actually and
reasonably incurred by Indemnitee or on Indemnitee's behalf in connection
therewith.

     7. Indemnification for Expenses When Indemnitee is Partly Successful.
Notwithstanding any provision to the contrary contained herein, if, in any
Proceeding, Indemnitee is successful, on the merits or otherwise, as to one or
more but fewer than all claims, counts, issues or matters in such Proceeding,
the Company shall indemnify Indemnitee in accordance with Section 3 of this
Agreement in connection with each such successful claim, count, issue or matter.
For purposes of this Agreement, and, without limiting the generality of the
foregoing, the termination of any claim, count, issue or matter in such a
Proceeding by dismissal, with or without prejudice, is to be construed as a
successful result as to such claim, count, issue or matter from the perspective
of the Person requesting such dismissal.

     8. Effect of Certain Resolutions. Neither the settlement or termination of
any Proceeding nor the failure of the Company to award indemnification or to
determine that indemnification is payable creates an adverse presumption that
Indemnitee is not entitled to indemnification hereunder. In addition, the
termination of any Proceeding by judgment, order, settlement, conviction, or
upon a plea of nolo contendere or its equivalent does not create a presumption
that Indemnitee did not act in good faith and in a manner that Indemnitee
reasonably believed to be in, or not opposed to, the best interests of the
Company or, with respect to any criminal action or proceeding, had reasonable
cause to believe that Indemnitee's action was unlawful.

     9. Agreement to Advance Expenses; Conditions. The Company shall, to the
extent not prohibited by law, pay to Indemnitee all Expenses incurred by
Indemnitee in connection with a Proceeding, including those incurred by
Indemnitee in connection with any Proceeding by or in the right of the Company,
in advance of the final disposition of the Proceeding to which the Indemnifiable
Expenses relate, if Indemnitee furnishes the Company with a written undertaking
to repay the amount of such Expenses advanced to Indemnitee if it is finally
determined by a court of competent jurisdiction that Indemnitee is not entitled
under this Agreement to indemnification. This undertaking is an unlimited
general obligation of Indemnitee, which the

                                        6

<PAGE>

Company shall accept without regard to the financial ability of Indemnitee to
make repayment, and in no event is be required to be secured.

     10. Procedure for Advance Payment of Expenses. Indemnitee shall submit to
the Company a written request specifying the Expenses for which Indemnitee seeks
an advancement under Section 9 of this Agreement, together with documentation
evidencing that Indemnitee has incurred such Expenses. The Company shall pay
Expenses under Section 9 no later than fifteen (15) days after the Company's
receipt of such request.

     11. Procedure Upon Request for Payment of Indemnifiable Amounts and
Expenses.

          (a) Upon written request by Indemnitee for payment pursuant to
Sections 5 and 10 of this Agreement, a determination, if required by applicable
law, with respect to Indemnitee's entitlement thereto shall be made in the
specific case: (i) if a Change in Control shall have occurred, by Independent
Counsel in a written opinion to the board of directors, a copy of which shall be
delivered to Indemnitee; or (ii) if a Change in Control shall not have occurred,
(A) by a majority vote of the Disinterested Directors, even though less than a
quorum of the board of directors, (B) by a committee of Disinterested Directors
designated by a majority vote of the Disinterested Directors, even though less
than a quorum of the board of directors, (C) if there are no such Disinterested
Directors or, if such Disinterested Directors so direct, by Independent Counsel
in a written opinion to the board of directors, a copy of which shall be
delivered to Indemnitee or (D) if so directed by the board of directors, by the
stockholders of the Company; and, if it is so determined that Indemnitee is
entitled to indemnification, payment to Indemnitee shall be made within ten (10)
days after such determination. Indemnitee shall cooperate with the person,
persons or entity making such determination with respect to Indemnitee's
entitlement to indemnification, including providing to such person, persons or
entity upon reasonable advance request any documentation or information which is
not privileged or otherwise protected from disclosure and which is reasonably
available to Indemnitee and reasonably necessary to such determination. Any
costs or Indemnifiable Expenses (including attorneys' fees and disbursements)
incurred by Indemnitee in so cooperating with the person, persons or entity
making such determination shall be borne by the Company (irrespective of the
determination as to Indemnitee's entitlement to indemnification) and the Company
hereby indemnifies and agrees to hold Indemnitee harmless therefrom.

          (b) In the event the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section 11(a) hereof, the
Independent Counsel shall be selected as provided in this Section 11(b). If a
Change in Control shall not have occurred, the Independent Counsel shall be
selected by the board of directors, and the Company shall give written notice to
Indemnitee advising him of the identity of the Independent Counsel so selected.
If a Change in Control shall have occurred, the Independent Counsel shall be
selected by Indemnitee (unless Indemnitee shall request that such selection be
made by the board of directors, in which event the preceding sentence shall
apply), and Indemnitee shall give written notice to the Company advising it of
the identity of the Independent Counsel so selected. In either event, Indemnitee
or the Company, as the case may be, may, within ten (10) days after such written
notice of selection shall have been given, deliver to the Company or to
Indemnitee, as

                                        7

<PAGE>

the case may be, a written objection to such selection; provided, however, that
such objection may be asserted only on the ground that the Independent Counsel
so selected does not meet the requirements of "Independent Counsel" as defined
in Section 1 of this Agreement, and the objection shall set forth with
particularity the factual basis of such assertion. Absent a proper and timely
objection, the person so selected shall act as Independent Counsel. If such
written objection is so made and substantiated, the Independent Counsel so
selected may not serve as Independent Counsel unless and until such objection is
withdrawn or a court has determined that such objection is without merit. If,
within twenty (20) days after the later of submission by Indemnitee of a written
request for payment pursuant to Sections 5 and 10 hereof and the final
disposition of the Proceeding, no Independent Counsel shall have been selected
and not objected to, either the Company or Indemnitee may petition a court of
competent jurisdiction for resolution of any objection which shall have been
made by the Company or Indemnitee to the other's selection of Independent
Counsel and/or for the appointment as Independent Counsel of a person selected
by the Court or by such other person as the Court shall designate, and the
person with respect to whom all objections are so resolved or the person so
appointed shall act as Independent Counsel under Section 11(a) hereof. Upon the
due commencement of any judicial proceeding or arbitration pursuant to Section
12(a) of this Agreement, Independent Counsel shall be discharged and relieved of
any further responsibility in such capacity (subject to the applicable standards
of professional conduct then prevailing).

     12. Remedies of Indemnitee.

          (a) Right to Petition. If Indemnitee makes a request for payment of
Indemnifiable Amounts under Section 5 above or a request for an advancement of
Expenses under Section 10 above and the Company fails to make such payment or
advancement in a timely manner pursuant to the terms of this Agreement,
Indemnitee may petition the Chancery Court of the State of Delaware (the
"Delaware Court") in accordance with Section 20 hereof to enforce the Company's
obligations under this Agreement. Alternatively, Indemnitee, at his option, may
seek an award in arbitration to be conducted by a single arbitrator pursuant to
the Commercial Arbitration Rules of the American Arbitration Association.
Indemnitee shall commence such proceeding seeking an adjudication or an award in
arbitration within ninety (90) days following the date on which Indemnitee first
has the right to commence such proceeding pursuant to this Section 12(a). The
Company shall not oppose Indemnitee's right to seek any such adjudication or
award in arbitration.

          (b) Burden of Proof. In any action brought under Section 12(a) above,
the Company has the burden of proving by a preponderance of the evidence that
Indemnitee is not entitled to payment of Indemnifiable Amounts hereunder;
provided, however, that if prior to the commencement of such action, this form
of agreement has been approved by the holders of a majority of the voting power
of the capital stock of the Company, the Company has the burden of proving by
clear and convincing evidence that Indemnitee is not entitled to such
indemnification.

          (c) Reliance as Safe Harbor. For purposes of any determination of good
faith, Indemnitee shall be deemed to have acted in good faith if Indemnitee's
action is based on the records or books of account of the Enterprise, including
financial statements, or on information supplied to Indemnitee by the officers
of the Enterprise in the course of their duties,

                                        8

<PAGE>

or on the advice of legal counsel for the Enterprise or on information or
records given or reports made to the Enterprise by an independent certified
public accountant or by an appraiser or other expert selected with the
reasonable care by the Enterprise. The provisions of this Section 12(c) shall
not be deemed to be exclusive or to limit in any way the other circumstances in
which the Indemnitee may be deemed to have met the applicable standard of
conduct set forth in this Agreement.

          (d) Expenses. The Company shall reimburse Indemnitee in full for any
Indemnifiable Expenses incurred by Indemnitee in connection with investigating,
preparing for, litigating, defending or settling any action brought by
Indemnitee under Section 12(a) above, except where such action is resolved
wholly in favor of the Company.

          (e) Validity of Agreement. The Company is precluded from asserting in
any Proceeding, including, without limitation, an action under Section 12(a)
above, that the provisions of this Agreement are not valid, binding and
enforceable or that there is insufficient consideration for this Agreement and
shall stipulate that the Company is bound by all the provisions of this
Agreement.

          (f) Failure to Act Not a Defense. The failure of the Company
(including its board of directors or any committee thereof, independent legal
counsel, or stockholders) to make a determination concerning the permissibility
of the payment of Indemnifiable Amounts or the advancement of Expenses under
this Agreement is not a defense in any action brought under Section 12(a) above,
and does not create a presumption that such payment or advancement is not
permissible.

          (g) Indemnitee's Right to Counsel. If the Company fails to comply with
any of its obligations under this Agreement or if the Company or any other
Person takes any action to declare this Agreement void or unenforceable, or
institutes any action, suit or proceeding to deny or to recover from Indemnitee
the benefits provided to Indemnitee hereunder, Indemnitee may retain counsel of
Indemnitee's choice, at the expense of the Company, to represent Indemnitee in
connection with any such matter.

     13. Notice by Indemnitee. Indemnitee shall notify the Company promptly upon
being served with any summons, citation, subpoena, complaint, indictment,
information or other document relating to any Proceeding that may result in the
payment of Indemnifiable Amounts or the advancement of Expenses hereunder;
provided, however, that the failure to give any such notice does not disqualify
Indemnitee from the right, or otherwise affect in any manner any right of
Indemnitee, to receive payments of Indemnifiable Amounts or advancements of
Expenses except to the extent the Company's ability to defend in such Proceeding
is prejudiced thereby.

     14. Representations and Warranties of the Company. The Company represents
and warrants to Indemnitee as follows:

          (a) Authority. The Company has all necessary power and authority to
enter into and be bound by the terms of this Agreement, and the execution,
delivery and performance of this Agreement and the obligations of the Company
contemplated hereby have been duly authorized by the Company.

                                        9

<PAGE>

          (b) Enforceability. This Agreement is valid and binding obligation of
the Company, enforceable against the Company in accordance with its terms.

     15. Expenses. During Indemnitee's service as a director and/or officer, the
Company shall promptly reimburse Indemnitee for all reasonable out-of-pocket
expenses incurred by Indemnitee in connection with Indemnitee's service as a
director and or officer or member of any board committee.

     16. Contract Rights Not Exclusive. The rights to payment of Indemnifiable
Amounts and advancement of Expenses in this Agreement are in addition to any
other rights that Indemnitee has under applicable law, the Company's By-laws or
its Certificate, as each may be amended, modified or supplemented from time to
time (collectively, the "Organization Documents"), or any other agreement, vote
of stockholders or directors (or a committee of directors), or otherwise, both
as to action in Indemnitee's official capacity and as to action in any other
capacity as a result of Indemnitee's serving as a director and/or officer of the
Company.

     17. Contribution. To the fullest extent permissible under applicable law,
if the indemnification provided for in this Agreement is unavailable to
Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying
Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for
judgments, fines, penalties, excise taxes, amounts paid or to be paid in
settlement and/or for Indemnifiable Expenses, in connection with any claim
relating to an indemnifiable event under this Agreement, in such proportion as
is deemed fair and reasonable in light of all of the circumstances of such
Proceeding in order to reflect (i) the relative benefits received by the Company
and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to
such Proceeding; and/or (ii) the relative fault of the Company (and its
directors, officers, employees and agents) and Indemnitee in connection with
such event(s) and/or transaction(s).

     18. Successors. This Agreement is to (a) be binding upon all successors and
assigns of the Company (including any transferee of all or a substantial portion
of the business, stock or assets of the Company and any direct or indirect
successor by merger or consolidation or otherwise by operation of law), and (b)
be binding on and inure to the benefit of the heirs, personal representatives,
executors and administrators of Indemnitee. This Agreement will continue to
benefit Indemnitee and such heirs, personal representatives, executors and
administrators after Indemnitee has ceased to have Corporate Status.

     19. Subrogation. If any payment of Indemnifiable Amounts is made under this
Agreement, the Company is to be subrogated to the extent of such payment to all
of the rights of contribution or recovery of Indemnitee against other Persons,
and Indemnitee shall take, at the request of the Company, all reasonable action
necessary to secure such rights, including the execution of such documents as
are necessary to enable the Company to bring suit to enforce such rights.

     20. Governing Law; Change in Law; Consent to Jurisdiction. This Agreement
is to be governed by and construed and enforced under the laws of the State of
Delaware, without giving effect to the provisions thereof relating to conflicts
of law (the "Governing Law"). If a change in the Governing Law (whether by
statute or judicial decision) permits broader

                                       10

<PAGE>

indemnification or advancement of Expenses than is provided under the terms of
the Organization Documents or this Agreement, Indemnitee will be entitled to
such broader indemnification and advancements, and this Agreement will be deemed
to be amended to such extent. The Company and Indemnitee hereby irrevocably and
unconditionally (i) agree that any action or proceeding arising out of or in
connection with this Agreement shall be brought (except for an arbitration
proceeding commenced by Indemnitee in accordance with Section 12 hereof) only in
the Delaware Court, and not in any other state or federal court in the United
States of America or any court in any other country, (ii) consent to submit to
the exclusive jurisdiction of the Delaware Court for purposes of any action or
proceeding arising out of or in connection with this Agreement, (iii) appoint,
to the extent such party is not otherwise subject to service of process in the
State of Delaware, irrevocably RL&F Service Corp., One Rodney Square, 10th
Floor, 10th and King Streets, Wilmington, Delaware 19801 as its agent in the
State of Delaware as such party's agent for acceptance of legal process in
connection with any such action or proceeding against such party with the same
legal force and validity as if served upon such party personally within the
State of Delaware, (iv) waive any objection to the laying of venue of any such
action or proceeding in the Delaware Court, and (v) waive, and agree not to
plead or to make, any claim that any such action or proceeding brought in the
Delaware Court has been brought in an improper or inconvenient forum.

     21. Severability. Whenever possible, each provision of this Agreement is to
be interpreted in such a manner as to be effective and valid under applicable
law, but if any provision of this Agreement, or any clause thereof, is
determined by a court of competent jurisdiction (or arbitrator in an arbitration
proceeding commenced by Indemnitee in accordance with Section 12 hereof) to be
illegal, invalid or unenforceable, in whole or in part, such provision or clause
will be limited or deemed to be modified in its application to the minimum
extent necessary to make such provision or clause valid, legal and enforceable,
and the remaining provisions and clauses of this Agreement will remain fully
enforceable and binding on the parties.

     22. Indemnitee as Plaintiff. Except as provided in Section 12 of this
Agreement, Indemnitee is not entitled to payment of Indemnifiable Amounts or
advancement of Expenses with respect to any Proceeding brought by Indemnitee
against the Company, any Entity that it controls, or any director or officer
thereof or any third party, unless the Company consents to the initiation of
such Proceeding; provided, however, that this Section 22 does not apply to
affirmative defenses asserted by Indemnitee or any counterclaims by Indemnitee
that are resolved successfully (from Indemnitee's perspective) in an action
brought against Indemnitee.

     23. Modifications and Waiver. Except as provided in Section 20 above with
respect to changes in the Governing Law that broaden the right of Indemnitee to
be indemnified by the Company, no supplement, modification or amendment of this
Agreement will be effective unless executed in writing by each of the parties
hereto. No waiver of any of the provisions of this Agreement constitutes a
waiver of any other provisions of this Agreement, nor does such waiver
constitute a continuing waiver of the provisions subject to such waiver.

     24. General Notices. All notices, requests, demands and other
communications hereunder shall be in writing and shall be deemed to have been
duly given (a) when delivered by hand, (b) when transmitted by facsimile and

                                       11

<PAGE>

receipt is acknowledged, or (c) if mailed by certified or registered mail with
postage prepaid, on the third business day after the date on which it is so
mailed to such address as may have been furnished by any party to the others.

     25. Enforcement.

          (a) The Company expressly confirms and agrees that it has entered into
this Agreement and assumed the obligations imposed on it hereby in order to
induce Indemnitee to serve as a director or officer of the Company, and the
Company acknowledges that Indemnitee is relying upon this Agreement in serving
as a director or officer of the Company.

          (b) This Agreement constitutes the entire agreement between the
parties hereto with respect to the subject matter hereof and supersedes all
prior agreements and understandings, oral, written and implied, between the
Company and Indemnitee with respect to the subject matter hereof; provided,
however, that this Agreement is a supplement to and in furtherance of the
Certificate, the By-laws, applicable insurance and applicable law, and shall not
be deemed a substitute therefor, nor to diminish or abrogate any rights of
Indemnitee thereunder.

     26. Duration of Agreement. This Agreement shall continue until and
terminate upon the later of: (a) ten (10) years after the date that Indemnitee
shall have ceased to serve as a director or officer of the Company or (b) one
(1) year after the final termination of any Proceeding then pending in respect
of which Indemnitee is granted rights of indemnification or advancement of
Expenses hereunder and of any proceeding commenced by Indemnitee pursuant to
this Agreement relating thereto. This Agreement shall be binding upon the
Company and its successors and assigns and shall inure to the benefit of
Indemnitee and his heirs, executors and administrators.
