EXHIBIT 10.4

                              EMPLOYMENT AGREEMENT


     LMI  AEROSPACE,  INC.,  a Missouri  corporation  (the  "Corporation"),  and
MICHAEL J. BIFFIGNANI ("Employee") hereby agree as follows:

     1.  Employment.  The  Corporation  hereby  employs  Employee,  and Employee
accepts  employment  from  the  Corporation,   upon  the  terms  and  conditions
hereinafter set forth. Any and all employment agreements heretofore entered into
between the  Corporation and Employee are hereby  terminated and cancelled,  and
each of the parties hereto  mutually  releases and discharges the other from any
and all  obligations  and  liabilities  heretofore  or now existing  under or by
virtue of any such employment agreements,  it being the intention of the parties
hereto that this  Agreement,  effective  immediately,  shall supersede and be in
lieu of any and all prior employment agreements between them.

     2. Term of Employment.

        (A) The initial term of Employee's employment under this Agreement shall
commence on January 1, 2004 and shall terminate on December 31, 2005;  provided,
however,  that this  Agreement  shall be  automatically  extended for additional
terms of one year each unless not later than October 31 of any year beginning in
2005,  either  party has given  written  notice to the other party of its or his
intention not to extend the term of this Agreement; and provided,  further, that
the term of employment may be terminated  upon the earlier  occurrence of any of
the following events:

            (1) Upon the  termination of the business or corporate  existence of
      the Corporation;

            (2) At  the  Corporation's  option,  in the  event  the  Corporation
      determines  that  Employee is not  performing  the duties  required of him
      hereunder to the satisfaction of the Corporation;

            (3) Upon the death of the Employee;

            (4)  At  the  Corporation's  option,  if  Employee  shall  suffer  a
      permanent  disability;  (For the  purposes of this  Agreement,  "permanent
      disability"  means any  physical  or mental  impairment  that  renders the
      Employee  unable  for a period of six (6)  months or more to  perform  the
      essential   job   functions  of  his   position,   even  with   reasonable
      accommodation,  as determined by a physician  selected by the Corporation.
      The Employee acknowledges and agrees that he shall voluntarily submit to a
      medical or  psychological  examination  for the purpose of determining his
      continued  fitness to perform  the  essential  functions  of his  position
      whenever requested to do so by the Corporation.  If the Corporation elects
      to terminate the employment  relationship  on this basis,  the Corporation
      shall  notify  the  Employee  or his  representative  in  writing  and the
      termination  shall become effective on the date that such  notification is
      given;

            (5) At the  Corporation's  option,  upon  ten  (10)  calendar  days'
      written  notice to  Employee,  in the event of any  breach or  default  by
      Employee  of any of the terms of this  Agreement  or of any of  Employee's
      duties or  obligations  hereunder.  In lieu of providing ten (10) calendar
      days' advance written notice,  the  Corporation,  at its sole option,  may
      terminate the Employee's  services  immediately and pay him an amount that
      is equivalent to ten (10) calendar days of his salary, less any deductions
      required by law;

            (6) At the Corporation's option,  without any advance notice, in the
      event that the Employee  engages in conduct  which,  in the opinion of the
      Corporation,  (1) constitutes  dishonesty of any kind (including,  but not
      limited to, any misrepresentation of facts or falsification of records) in
      Employee's relations, interactions or dealings with the Corporation or its
      customers;  (2)  constitutes a felony;  (3) potentially may or will expose
      the  Corporation to public  disrepute or disgrace,  or potentially  may or
      will  cause  harm  to  the  customer  relations,  operations  or  business
      prospects of the Corporation; (4) constitutes harassment or discrimination
      towards any person  associated with the Corporation,  whether an employee,
      agent or customer,  based upon that person's race, color, national origin,
      sex, age,  disability,  religion,  or other protected status; (5) reflects
      disruptive  or disorderly  conduct,  including but not limited to, acts of
      violence, fighting, intimidation or threats of violence against any person
      associated with the Corporation,  whether an employee,  agent or customer,
      or possessing a weapon while on the Corporation's premises or while acting
      on behalf of the Corporation; (6) is indicative of abusive or illegal drug
      use  while  on  the   Corporation's   premises  or  while  acting  on  the
      Corporation's  behalf;  or (7)  constitutes  a  willful  violation  of any
      governmental rules or regulations; or

            (7) At the Employee's  option,  after providing the Corporation with
      at least thirty (30) calendar days advance written notice of his intention
      to terminate the employment relationship.

            If  employment  is  terminated  for any of the  reasons set forth in
      subparagraphs  (3) through (7) of this  section  2(A),  Employee  shall be
      entitled  to receive  only the Base  Salary  (as that term is  hereinafter
      defined) accrued but unpaid as of the date of the termination and shall be
      ineligible to receive any additional compensation or severance pay. If, on
      the other hand,  employment is terminated  by the  Corporation  during the
      term of this  Agreement  for any  reason  other  than  those  set forth in
      paragraphs (3) through (7) of this section 2(A), subject to the conditions
      set forth in paragraphs  2(C) and (D) of this  Agreement,  the Corporation
      shall provide severance pay to Employee in an amount based upon his length
      of service  with the  Corporation.  Specifically,  the  Corporation  shall
      provide  Employee  with six (6) months of Base  Salary if he has less than
      five (5)  years of  service  with  the  Corporation  as of the date of his
      termination  and with twelve (12) months of Base Salary if he has five (5)
      or more  years  of  service  with  the  Corporation  as of the date of his
      termination.   Such   severance   pay  shall  be  paid  in  equal  monthly
      installments,  unless the Corporation,  within its sole discretion, elects
      to pay the present  value of the severance pay in a lump sum within thirty
      (30) calendar days of the termination.

        (B) If  employment is  terminated  in  conjunction  with a change in the
control of the Corporation or in conjunction with the sale of substantially  all
of the  operating  assets  of the  Corporation,  the  Corporation  will  provide
Employee with severance pay under the  circumstances  specified in subparagraphs
(1) and (2) of this  paragraph  (B), and the  conditions set forth in paragraphs
2(C) and (D) of this Agreement. For the purposes of this Agreement, a "change in
control" is defined as the sale of substantially  all of the operating assets of
the Corporation or the acquisition of more than fifty percent (50%) of the stock
of the  Corporation  by a group of  shareholders  or an  entity  which  acquires
control of the Corporation (a "Purchaser").

            (1) If the change in control or the sale results in the  involuntary
      termination  of Employee or results in the Employee  electing to terminate
      his employment for a good reason as determined by the Corporation (such as
      the Purchaser  refusing to offer full time employment to Employee on terms
      comparable to those provided by the  Corporation  prior to the acquisition
      or the  Purchaser  requiring  Employee  to  move to a new  location),  the
      Corporation shall provide Employee with severance pay in an amount that is
      equal to two times his  annual  Base  Salary  and shall pay  Employee  any
      reasonably  anticipated  Performance Bonus for the fiscal year in which he
      was terminated on a prorated basis.

            (2) If Employee voluntarily terminates his employment without a good
      reason (as  determined by the  Corporation)  within ninety (90) days after
      the change in control or the sale, the Corporation  shall provide Employee
      with six (6)  months of Base  Salary if he has less than five (5) years of
      service with the  Corporation as of the date of his  termination  and with
      twelve  (12)  months of Base  Salary  if he has five (5) or more  years of
      service with the Corporation as of the date of his termination.

            (3) For purposes of this  paragraph  2(B),  in the event a change of
      control  occurs  after  April 1,  2005,  Employee  may take up to nine (9)
      months  from the date of change of  control  to claim  severance  pay,  as
      provided in paragraph 2(B)(1) and (2).

        (C) The  severance  pay provided  for in section 2(A) of this  Agreement
shall be paid in equal monthly installments,  unless the Corporation, within its
sole discretion,  elects to pay the present value of the severance pay in a lump
sum within  thirty  (30)  calendar  days of the  termination.  For  purposes  of
calculating  the present value of the severance  pay, the discount rate shall be
the prime rate  quoted in the Wall  Street  Journal  on the day the  Corporation
elects to pay the present value of the severance pay in a lump sum.

        (D)  Notwithstanding  anything  to  the  contrary,  (i)  the  amount  of
severance pay provided  under this Agreement  shall not under any  circumstances
exceed  the  limitations  set  forth  in ss.  280G of the  Code,  and  (ii)  the
Corporation's obligation to pay the severance pay provided for in this section 2
shall be conditioned on Employee's  execution of a written release  satisfactory
to the Corporation

     3. Compensation.

        (A) During the period from  January 1, 2004 to December  31,  2004,  the
Corporation shall compensate Employee for Employee's services rendered hereunder
by paying to  Employee  an annual  salary  (the "Base  Salary")  of One  Hundred
Fifty-five  Thousand  Dollars  ($155,000.00),  less any  authorized  or required
payroll deductions. Thereafter, as long as this Agreement remains in effect, the
annual  Base  Salary  that the  Corporation  shall pay to the  Employee  for his
services  rendered  hereunder will be One Hundred  Sixty-five  Thousand  Dollars
($165,000.00),  less any authorized or required payroll  deductions.  Payment of
this  salary  will  be made in  accordance  with  the  payroll  policies  of the
Corporation in effect from time to time.

        (B) With respect to each complete fiscal year of the Corporation  during
which (i) the Employee is employed  under the terms of this  Agreement as of the
last day of such fiscal year, and (ii) the Corporation's "Annual Net Income" (as
that  term  is   hereinafter   defined)  is  more  than  One   Million   Dollars
($1,000,000.00),  the Corporation shall pay to Employee, in addition to the Base
Salary,  an annual  "Performance  Bonus".  The amount of the annual  Performance
Bonus (if any) shall be equal to:

     (1)  seven tenths of one percent  (0.70%) of the  Corporation's  Annual Net
          Income  that is between One Million  Dollars  ($1,000,000.00)  and One
          Million, Nine Hundred Ninety-Nine  Thousand,  Nine Hundred Ninety-Nine
          Dollars and Ninety-Nine Cents ($1,999,999.99); plus

     (2)  one percent  (1.00%) of the  Corporation's  Net Income that is between
          Two  Million  Dollars   ($2,000,000.00)   and  Eight  Million  Dollars
          ($8,000,000.00), inclusive.

     In the event the Corporation's  Annual Net Income for any given fiscal year
is less than One Million  Dollars  ($1,000,000.00),  the  Employee  shall not be
entitled  to  a   Performance   Bonus  with   respect  to  such   fiscal   year.
Notwithstanding  anything contained herein to the contrary, in the event the sum
of the  Employee's  Performance  Bonus with  respect  to a fiscal  year plus the
Employee's  benefit under all  performance/production  incentive programs of the
Corporation in which the Employee is entitled to a bonus  ("Incentive  Benefit")
for such fiscal year exceeds  Sixty-seven  Thousand  Dollars  ($67,000.00),  the
amount of the  Employee's  Performance  Bonus for such year  shall be reduced so
that  the  sum of  the  Performance  Bonus  and  the  Incentive  Benefit  equals
Sixty-seven Thousand Dollars ($67,000.00).

     For purposes of the calculation of the Performance Bonus, the Corporation's
"Annual Net Income" means the consolidated net profit of the Corporation and its
subsidiaries,  for a given fiscal year, as determined by the firm of independent
certified public  accountants  providing  auditing  services to the Corporation,
using  generally  accepted  accounting  principles   consistently  applied,  and
calculated without regard to (a) any bonus paid to the Corporation's Chairman of
the Board and any formula  bonuses paid  pursuant to employment  contracts,  (b)
federal and state  income tax,  and (c) any income or loss  attributable  to any
other  corporation  or entity  (including  the assets of a corporation or entity
that  constitute  an  operating   business)  acquired  by  or  merged  into  the
Corporation subsequent to the effective date of this Agreement.  The Corporation
shall pay to Employee any Performance Bonus due the Employee hereunder not later
than  fifteen  (15) days  after the  receipt  by the  Corporation  of its annual
audited financial  statements,  which the Corporation  expects to receive within
ninety (90) days after the end of each fiscal year of the Corporation.

        (C) In  addition  to the Base  salary  and  Performance  Bonus (if any),
Employee  shall be entitled to receive such bonus  compensation  as the Board of
Directors of the Corporation may authorize from time to time.

        (D) The Corporation  retains the right to modify or adjust the manner in
which the  Performance  Bonus is  calculated  in the event that the  Corporation
either acquires the assets of another entity,  or any portion thereof,  or sells
its assets, or any portion thereof, to another entity.

     4. Duties of Employee.

        (A)  Employee  shall  serve as  Chief  Information  Officer/Director  of
Supplier  Management  and  Procurement  of  the  Corporation  or in  such  other
positions as may be determined by the Board of Directors of the Corporation, and
Employee  shall  perform  such  duties  on  behalf  of the  Corporation  and its
subsidiaries  by such  means,  at such  locations,  and in such manner as may be
specified  from  time to time by the  officers  or  Board  of  Directors  of the
Corporation.

        (B) Employee agrees to abide by and conform to all rules  established by
the Corporation applicable to its employees.

        (C)  Employee  acknowledges  that he is being  employed  as a  full-time
employee,  and  Employee  agrees to devote so much of  Employee's  entire  time,
attention  and energies to the business of the  Corporation  as is necessary for
the successful  operation of the  Corporation and shall endeavor at all times to
improve the business of the Corporation.  Employee shall not accept any business
commitments other than with the Corporation  without the advance written consent
of the Corporation's President.

     5.  Expenses.  During  the  period  of  Employee's  employment,  except  as
otherwise  specifically  provided in this Agreement,  the  Corporation  will pay
directly,  or reimburse  Employee  for, all items of  reasonable  and  necessary
business  expenses  approved in advance by the  Corporation if such expenses are
incurred by Employee in the  interest of the  business of the  Corporation.  The
Corporation  shall also reimburse  Employee for automobile  expenses incurred by
Employee in the performance of Employee's duties  hereunder.  The amount of such
reimbursement  shall be in accordance with the automobile expense  reimbursement
policy  adopted  (and  as  it  may  be  modified  from  time  to  time)  by  the
Corporation's  Board of  Directors.  All such  expenses paid by Employee will be
reimbursed by the Corporation upon  presentation by Employee,  from time to time
(but not less than quarterly),  of an itemized  account of such  expenditures in
accordance with the Corporation's policy for verifying such expenditures.

     6. Fringe Benefits.

        (A) Employee shall be entitled to  participate  in any health,  accident
and  life  insurance  program  and  other  benefits  which  have  been or may be
established by the Corporation for salaried employees of the Corporation.

        (B)  Employee  shall be entitled to an annual  vacation  without loss of
compensation  for such period as may be  determined by the Board of Directors of
the Corporation.

        (C) The Corporation shall furnish to the Employee during the term of his
employment an automobile  selected by the Corporation to aid the Employee in the
performance of his duties.  Upon agreement of the  Corporation and the Employee,
the Corporation may, in lieu of the automobile, provide the Employee with a Five
Thousand Dollar ($5,000.00) annual automobile allowance.

     7. Covenants of Employee.

        (A) During the term of Employee's  employment  with the  Corporation and
for all time thereafter  Employee covenants and agrees that Employee will not in
any manner  directly or indirectly,  except as required in Employee's  duties to
the  Corporation,  disclose  or divulge to any person,  entity,  firm or company
whatsoever,  or use for  Employee's  own  benefit  or the  benefit  of any other
person, entity, firm or company, directly or indirectly, any knowledge, devices,
information,  techniques, customer lists, business plans or other data belonging
to the Corporation or developed by Employee on behalf of the Corporation  during
his  employment  with the  Corporation,  without  regard to  whether  all of the
foregoing  matters  will be deemed  confidential,  material  or  important,  the
parties  hereto  stipulating,  as  between  them,  that the same are  important,
material,  confidential and the property of the Corporation,  that disclosure of
the  same to or use of the  same by  third  parties  would  greatly  affect  the
effective  and  successful  conduct of the business of the  Corporation  and the
goodwill  of the  Corporation,  and  that  any  breach  of  the  terms  of  this
subparagraph (A) shall be a material breach of this Agreement.

        (B) During the term of Employee's  employment  with the  Corporation and
for a period of two (2) years or one (1) year with respect to subparagraph  (iv)
below  (the  "Covenant  Term")  after  cessation  for  whatever  reason  of such
employment (except as hereinafter provided in subparagraph (C) of this paragraph
7), Employee  covenants and agrees that Employee will not in any manner directly
or indirectly:

            (1)  solicit,  divert,  take  away  or  interfere  with  any  of the
      customers  (or  their   respective   affiliates  or   successors)  of  the
      Corporation;

            (2)  engage  directly  or  indirectly,  either  personally  or as an
      employee,  partner,  associate partner,  officer, manager, agent, advisor,
      consultant or  otherwise,  or by means of any corporate or other entity or
      device,  in any  business  which is  competitive  with the business of the
      Corporation.  For  purposes  of this  covenant a  business  will be deemed
      competitive  if it is conducted in whole or in part within any  geographic
      area wherein the Corporation is engaged in marketing its products,  and if
      it involves the manufacture of component parts for the aerospace  industry
      or any other business which is in any manner  competitive,  as of the date
      of  cessation  of  Employee's  employment,  with any  business  then being
      conducted  by the  Corporation  or as to which  the  Corporation  has then
      formulated definitive plans to enter;

            (3)  induce  any  salesman,  distributor,   supplier,  manufacturer,
      representative,  agent,  jobber or other person transacting  business with
      the Corporation to terminate their  relationship with the Corporation,  or
      to represent,  distribute or sell products in competition with products of
      the Corporation; or

            (4) induce or cause any  employee  of the  Corporation  to leave the
      employ of the Corporation.

        (C) The  parties  agree  that  the  Covenant  Term  provided  for in the
preceding subparagraph (B) shall be:

            (1)  reduced  to six (6)  months in the  event all of the  operating
      assets or all of the common stock of the Corporation is sold to any entity
      or  individuals  unaffiliated  with the  Corporation,  its  successors  or
      assigns; or

            (2) eliminated if the business currently operated by the Corporation
      is terminated and the assets of the Corporation are liquidated.

        (D) All the covenants of Employee contained in this paragraph 7 shall be
construed as agreements  independent of any other  provision of this  Agreement,
and the  existence  of any claim or cause of  action  against  the  Corporation,
whether  predicated  on this  Agreement  or  otherwise,  shall not  constitute a
defense to the enforcement by the Corporation of these covenants.

        (E) It is the  intention  of the parties to restrict the  activities  of
Employee under this paragraph 7 only to the extent  necessary for the protection
of  legitimate   business   interests  of  the  Corporation,   and  the  parties
specifically  covenant  and agree that  should any of the  provisions  set forth
therein,  under any set of  circumstances  not now foreseen by the  parties,  be
deemed too broad for such purpose,  said provisions  will  nevertheless be valid
and enforceable to the extent necessary for such protection.

     8. Documents. Upon cessation of Employee's employment with the Corporation,
for whatever  reason,  all documents,  records  (including  without  limitation,
customer records), notebooks, invoices, statements or correspondence,  including
copies thereof,  relating to the business of the Corporation  then in Employee's
possession,  whether  prepared by Employee or others,  will be  delivered to and
left with the  Corporation,  and  Employee  agrees  not to retain  copies of the
foregoing documents without the written consent of the Corporation.

     9. Remedies.  In the event of the breach by Employee of any of the terms of
this  Agreement,  notwithstanding  anything to the  contrary  contained  in this
Agreement,   the  Corporation  may  terminate  the  employment  of  Employee  in
accordance with the provisions of paragraph 2 of this  Agreement.  It is further
agreed  that any  breach or  evasion  of any of the terms of this  Agreement  by
Employee will result in immediate and irreparable  injury to the Corporation and
will authorize recourse to injunction and/or specific  performance as well as to
other legal or equitable  remedies to which the Corporation may be entitled.  In
addition  to any  other  remedies  that  it may  have  in  law  or  equity,  the
Corporation  also may  require  an  accounting  and  repayment  of all  profits,
compensation,  remuneration or other benefits realized,  directly or indirectly,
as a result of such  breaches  by the  Employee  or by a  competitor's  business
controlled,  directly or indirectly, by the Employee. No remedy conferred by any
of the specific  provisions of this Agreement is intended to be exclusive of any
other  remedy and each and every  remedy  given  hereunder  or now or  hereafter
existing at law or in equity by statute or otherwise. The election of any one or
more remedies by the  Corporation  shall not constitute a waiver of the right to
pursue other available remedies. Employee expressly agrees to pay all reasonable
costs and  attorneys'  fees incurred by the  Corporation in order to enforce the
Employee's obligations under this Agreement, regardless of whether litigation is
commenced or prosecuted to a judgment.

     10.  Severability.  All  agreements  and  covenants  contained  herein  are
severable, and in the event any of them shall be held to be invalid by any court
of competent jurisdiction,  this Agreement, subject to subparagraph 7(E) hereof,
shall  continue  in full force and effect  and shall be  interpreted  as if such
invalid agreements or covenants were not contained herein.

     11. Waiver or Modification.  No waiver or modification of this Agreement or
of any covenant, condition or limitation herein shall be valid unless in writing
and duly executed by the party to be charged  therewith,  and no evidence of any
waiver  or  modification  shall  be  offered  or  received  in  evidence  in any
proceeding,  arbitration or litigation between the parties hereto arising out of
or  affecting  this  Agreement,  or the  rights or  obligations  of the  parties
hereunder,  unless such waiver or modification  is in writing,  duly executed as
aforesaid,  and the parties  further agree that the provisions of this Paragraph
may not be waived  except as herein set forth.  Failure  of the  Corporation  to
exercise or  otherwise  act with  respect to any of its rights  hereunder in the
event of a breach of any of the terms or conditions hereof by Employee shall not
be  construed  as a waiver of such  breach  nor  prevent  the  Corporation  from
thereafter  enforcing  strict  compliance  with  any  and all of the  terms  and
conditions hereof.

     12.  Assignability.  This  Agreement may be assigned by the  Corporation to
another  entity  which  purchases   substantially  all  of  the  assets  of  the
Corporation or acquires a majority of the stock of the Corporation. The services
to be performed  by Employee  hereunder  are personal in nature and,  therefore,
Employee shall not assign Employee's rights or delegate  Employee's  obligations
under this  Agreement,  and any attempted or purported  assignment or delegation
not herein permitted shall be null and void.

     13.  Successors.  Subject to the provisions of paragraph 12, this Agreement
shall be binding  upon and shall  inure to the  benefit of the  Corporation  and
Employee  and  their  respective   heirs,   executors,   administrators,   legal
administrators, successors and assigns.

     14.  Notices.  Any  notice or other  communication  required  or  permitted
hereunder  shall  be in  writing  and  shall be  deemed  to have  been  given if
delivered personally, by over-night courier, or by certified or registered mail,
return receipt requested, if to the Corporation, to:

                  Ronald S. Saks, President
                  LMI AEROSPACE, INC.
                  P.O. Box 900
                  St. Charles, MO  63302-0900

and, if to Employee, to:

                  2643 Joyceridge
                  Chesterfield, MO 63017

or to such other  address as may be  specified  by either of the  parties in the
manner provided under this paragraph 14.

     15.  Construction.  This Agreement shall be deemed for all purposes to have
been made in the State of Missouri  and shall be governed  by and  construed  in
accordance  with the laws of the State of Missouri,  notwithstanding  either the
place  of  execution  hereof,  nor the  performance  of any  acts in  connection
herewith or hereunder in any other jurisdiction.
