Re:      Employment Agreement

Dear Michael:

         This letter agreement (this "Agreement") sets forth the terms under
which you are employed by Chart Industries, Inc. (the "Company") as its Chief
Financial Officer.

1.       Term of Employment. The Company agrees to employ you, and you agree to
serve the Company, on the terms and conditions set forth in this Agreement for
the period commencing as of the date hereof and expiring on the first
anniversary of the date hereof (the "Employment Period"). The Employment Period
shall automatically be extended on the first anniversary of the date hereof, and
on each subsequent anniversary of the date hereof, for a period of one year from
such anniversary unless, not later than 60 days before such anniversary, you or
the Company has given written notice to the other party that you or it, as the
case may be, does not wish to have the Employment Period extended.
Notwithstanding the foregoing, in the event of a Change in Control, the
Employment Period shall automatically be extended for a period beginning on the
date of the Change in Control and expiring on the second anniversary of the date
of such Change in Control, but the Employment Period shall not be extended
further after a Change in Control unless expressly agreed to in writing by the
parties. In any case, the Employment Period may be terminated earlier under the
terms and conditions set forth herein.

2.       Position and Duties. During the Employment Period, you shall serve as
the Company's Chief Financial Officer and report to the Chief Executive Officer
of the Company. You shall have responsibility for the accounting, financial
reporting, treasury, internal audit, tax and administrative functions of the
Company, and the performance of such other services and duties as shall be
reasonably assigned to and requested of you by the Chief Executive Officer or
the Board of Directors. You agree to devote substantially all your working time
and efforts to the business and affairs of the Company and serve the Company in
its business and perform your duties to the best of your ability.

3.       Compensation and Benefits.

         (a) Salary. During the Employment Period, you shall receive a base
salary at the rate of Two Hundred Thousand Dollars ($200,000) per year (the
"Base Salary Amount"). Your salary may be adjusted based upon an annual review
by the Board of Directors of the Company or any duly authorized Committee
thereof, although any such adjustment shall be at the sole discretion of the
Board of Directors or such Committee. Notwithstanding the foregoing, in no

event shall your salary be adjusted below the Base Salary Amount. Such salary
shall be payable in bi-weekly installments or otherwise in accordance with the
normal policies of the Company for payment of corporate officers.

         (b) Benefits. During the Employment Period, you shall be entitled to
participate in any employee benefits plans which are maintained or established
by the Company for its corporate officers, subject, however, to all of the terms
and conditions thereof, including any eligibility requirements therefor,
including but not limited to: (i) the Management Incentive Compensation Plan or
any other successor plan (the "Incentive Plan"); (ii) any stock option plan of
the Company in which the Company's corporate officers generally are eligible to
participate (the "Option Plan"); (iii) medical, dental and vision insurance
coverage; (iv) life insurance coverage; (v) 401(k) Retirement Plan; (vi) four
weeks of paid vacation annually to be taken at such time or times as are chosen
by you; and (vii) the use of a leased automobile (including insurance).
Notwithstanding the foregoing, you shall not be entitled to participate in the
Company's Severance Benefit Plan or any such successor plan. Payment under the
Incentive Plan shall be determined by, and awarded in the sole discretion of,
the Board of Directors of the Company or any authorized Committee thereof and
shall be dependent upon the Company's financial performance and your performance
toward established goals. There shall be no guaranteed awards under the
Incentive Plan. On an annual basis, the Board of Directors of the Company or any
authorized Committee thereof may in its sole discretion grant you options to
purchase common stock of the Company under the Option Plan in addition to any
option previously granted to you.

         (c) Expenses. The Company shall reimburse you for reasonable expenses
incurred by you on behalf of the Company in the performance of your duties
during the Employment Period. You shall furnish the Company with such
documentation as is requested by the Company in order for it to comply with the
Internal Revenue Code of 1986, as amended, and regulations thereunder in
connection with the proper deduction of such expenses.

4.       Termination of Employment.

         (a) General. Your employment with the Company shall terminate
automatically upon your death or the expiration of the Employment Period without
extension. In addition, you may terminate your employment with the Company
voluntarily by resigning, and the Company may terminate your employment (i) for
Cause, (ii) without Cause, for any reason or no reason, or (iii) by reason of
your Disability. Any termination by the Company or by you of your employment
hereunder shall be communicated by a written notice to the other party hereto,
which shall indicate the specific termination provision in this Agreement relied
upon, set forth in reasonable detail the facts and circumstances claimed to
provide a basis for termination of your employment under the provision so
indicated, and specify the effective date of the termination of your employment
(which shall not be earlier than the date on which the notice is given). The
effective date of the termination of your employment is referred to as the
"Termination Date." Notwithstanding Section 1, the Employment Period shall
terminate upon the termination of your employment with the Company.

         (b) Expiration of Employment Period, Death, Resignation, Cause or
Disability. If the Employment Period expires without extension or, during the
Employment Period, your employment terminates as a result of your death, you
terminate your employment voluntarily by resigning, or the Company terminates
your employment for Cause or by reason of your Disability, then, in any such
case, Sections 4(c), 4(d) and 4(e) shall not apply and you shall be entitled to
payment of base salary only for the remainder of the month in which such
termination occurs (or only until the Termination Date, if your employment
terminates as a result of the expiration of the Employment Period without
extension) and thereafter such salary shall end and cease to be payable. In
addition, in any such case, and you shall be entitled to receive any benefits
provided for in Section 3(b) which have accrued up to and including the
Termination Date, subject to the terms and conditions of the benefit plans
referenced in Section 3(b), and reimbursement of reasonable expenses incurred up
to and including the Termination Date under the terms of Section 3(c).

         (c) Termination Without Cause. If, during the Employment Period, the
Company terminates your employment without Cause, then, in lieu of further base
salary payments hereunder, the Company shall pay to you within 30 calendar days
after the Termination Date an amount equal to your then current annual base
salary. In addition, in such case, you shall be entitled to receive any benefits
provided for in Section 3(b) which have accrued up to and including the
Termination Date, subject to the terms and conditions of the benefit plans
referenced in Section 3(b), and reimbursement of reasonable expenses incurred up
to and including the Termination Date under the terms of Section 3(c).
Notwithstanding the foregoing, you shall not be entitled to any payment or
benefit under this Section 4(c) if you are entitled to any salary continuation
under Section 4(d), and in no case shall you be entitled to any payments and/or
benefits under both Section 4(c) and Section 4(d).

         (d) Termination Without Cause Following a Change in Control. If (i) a
Change in Control occurs during the Employment Period and (ii) at any time
during the period commencing on the date of such Change in Control and ending on
the date that is six months after such Change in Control the Company terminates
your employment without Cause, then, in lieu of any payment or benefits under
Section 4(c), the Company shall continue to pay to you, in accordance with its
normal payroll practices, your base salary at the rate in effect immediately
prior to the Termination Date (which shall not be less than the Base Salary
Amount) until the second anniversary of such Termination Date. In addition, in
such case, you shall be entitled to receive any benefits provided for in Section
3(b) which have accrued up to and including the Termination Date, subject to the
terms and conditions of the benefit plans referenced in Section 3(b), and
reimbursement of reasonable expenses incurred up to and including the
Termination Date under the terms of Section 3(c). For purposes of clauses (i)
and (ii) of this Section 4(d), any termination of your employment during the
Employment Period by the Company without Cause after or immediately before the
Company enters into a definitive agreement with a third party that results in a
Change in Control shall be deemed to be a termination of your employment by the
Company without Cause immediately after such Change in Control, and such Change
in Control shall be deemed to occur during the Employment Period.

         (e) Continuation of Health Benefits. If, during the Employment Period,
the Company terminates your employment without Cause, then for the duration of
the Applicable Continuation Period you shall be eligible to participate in the
Company's medical, dental and vision insurance coverage available to its
employees generally as if you were still employed by the Company, to the extent
and at the level of your participation in that coverage immediately prior to the
Termination Date, but all Company contributions or payments under that coverage
shall be subject to your fulfillment of your contribution requirements under
that coverage, and Company provision of this coverage shall cease if you obtain
comparable coverage from another employer during the Applicable Continuation
Period. If, however, your continued participation in any such insurance coverage
after the Termination Date is not possible under the terms governing such
coverage, the Company may satisfy its obligation to provide such coverage by
providing to you during the Applicable Continuation Period alternative coverage,
comparable to the coverage then available to Company employees generally, on the
terms set forth in the preceding sentence. The "Applicable Continuation Period"
means 12 months after the Termination Date if you are entitled to severance pay
under Section 4(c), and means 24 months after the Termination Date if you are
entitled to severance pay under Section 4(d).

5.       Binding Agreement; Successors. This Agreement shall inure to the
benefit of and be binding upon your personal or legal representatives,
executors, administrators, successors, heirs, distributees, devisees and
legatees. If you should die while any amounts would still be payable to you
hereunder, all such amounts, unless otherwise provided herein, shall be paid in
accordance with the terms of this Agreement to your spouse, or if your spouse
does not survive you, to your estate. This Agreement shall inure to the benefit
of and be binding upon the successors and assigns of the Company, including,
without limitation, any person acquiring directly or indirectly all or
substantially all of the assets of the Company, whether by merger,
consolidation, sale or otherwise (and such successor shall thereafter be deemed
the "Company" for the purposes of this Agreement). The Company shall require any
such successor to assume and agree to perform this Agreement.

6.       Withholding. The Company may withhold from any amounts payable under or
in connection with this Agreement all federal, state, local and other taxes as
may be required to be withheld by the Company under applicable law or
governmental regulation or ruling.

7.       Headings; Definitions. The headings contained herein are for reference
purposes only and shall not in any way affect the meaning or interpretation of
this Agreement. Certain terms used in this Agreement are defined on Appendix A
attached hereto.

8.       Entire Agreement. This Agreement contains the entire agreement between
the parties with respect to your employment and supersedes any and all other
agreements (including the letter agreement, dated July 25, 2001, between the
Company and you relating to severance pay, which is hereby terminated, but
excluding any existing stock option granted to you and any rights you may have
to indemnity), either oral or in writing, with respect to your employment.

9.       General. No provision of this Agreement may be modified, waived or
discharged unless such waiver, modification or discharge is agreed to in
writing, and is signed by you and by another officer of the Company. You may not
assign this Agreement without the consent of the Company.

         the Company has or may have occurred or will or may occur in the future
         by reason of such beneficial ownership, (B) solely because the Company
         or any other person, group or entity directly involved in the
         restructuring of the Company's capital and debt arrangements related to

         it of shares of Voting Stock acquired from the Company in connection
         with such restructuring or because the Company reports that a change in
         control of the Company has or may have occurred or will or may occur in
         the future by reason of such transaction, but only if both (1) the

         transaction is held in the aggregate by the holders of Voting Stock
         immediately prior to such transaction, or (C) solely because of a
         change in control of any Subsidiary.

         For purposes of this definition of "Change in Control", the following
         capitalized terms shall have the following meanings:

               "Director" means a member of the Board of Directors of the
               Company.

               "Exchange Act" means the Securities Exchange Act of 1934, as
               amended, and the rules and regulations thereunder, as such law,
               rules and regulations may be amended from time to time.

               "Related Person" means (i) Arthur S. Holmes (ii) Charles S.
               Holmes, (iii) any person, group or entity controlled directly, or

               Holmes or Charles S. Holmes or both of them, and (iv) any of the
               foregoing acting alone or in concert.

               "Subsidiary" means a corporation, company or other entity (i)
               more than 50 percent of whose outstanding shares or securities
               (representing the right to vote for the election of directors or
               other managing authority) are, or (ii) which does not have
               outstanding shares or securities (as may be the case in a
               partnership, joint venture or unincorporated association), but
               more than 50 percent of whose ownership interest representing the
               right generally to make decisions for such other entity is, now
               or hereafter, owned or controlled, directly or indirectly, by the
               Company.

               "Voting Power" means, at any time, the total votes relating to
               the then-outstanding securities entitled to vote generally in the
               election of Directors.

of performing the essential functions of your position with or without
reasonable accommodations for the Company as previously performed shall be
conclusive of the fact that you are incapable of performing such services and
are, or have been, disabled for the purposes of this Agreement. The Company and
you acknowledge and agree that the essential functions of your position are
unique and critical to the Company and that a disability condition that causes
you to be unable to perform the essential functions of your position under the
circumstances described above will constitute an undue hardship on the Company.

"You," "your" and similar derivations of "you" mean and refer to Michael F.
Biehl.
