Dear Chris:

It is our pleasure to confirm the commitment of The CIT Group/Equipment
Financing, Inc. (CIT) to make loans to Survival Technology, Inc. (Borrower)
up to an aggregate principal sum of Three Million Dollars ($3,000,000.00),
for the purpose of enabling Borrower to acquire the Equipment described
below.  This commitment letter replaces and supersedes the commitment letter,
dated March 21, 1995, addressed to William Rich, and accepted on April 8,
1995, on behalf of Borrower by Jeffrey W. Church. Our commitment is subject
to the following terms and conditions.

1.    AMOUNT
      The maximum aggregate amount of the loans will be the sum of $3,000,000.00
      representing one hundred percent (100%) of the Borrower's invoice cost
      including freight and taxes for the Equipment described in Paragraph 2.

2.    EQUIPMENT/COLLATERAL
      The Equipment to be purchased will consist of the following items:
      Production Molds, Equipment and Facility renovations.

      Our loan will be collateralized by a valid and perfected first security
      interest in the above-mentioned Equipment, and such Equipment shall not
      to be subject to any junior security interests, except for the security
      interest granted pursuant to the Merrill Lynch agreement referred to in
      Paragraph 3 hereof, which security interest shall be subordinated to
      ours in a manner satisfactory to us.

3.    OTHER TERMS AND CONDITIONS
      Our commitment herein to make any loans that exceed $1,500,000 in the
      aggregate is contingent upon our receipt from a participant/assignee of
      funds to purchase a participation interest in our loans or an assignment
      of such loans, in the amount of such excess.

      Our loan documents will contain as an event of default the existence of
      an uncured or unwaived default under the WCMA Note, Loan and Security
      Agreement, dated November 4, 1993, between Merrill Lynch Business
      Financial Services Inc. and Borrower, as supplemented by a Letter
      Agreement, dated October 7, 1994.

4.    RATE OF INTEREST
      Each loan, prior to maturity, shall bear interest at a rate equal to the
      Treasury Yield (as defined below) plus 247 Basis Points.  Interest shall
      be computed on the basis of a year of 360 days.  The Treasury Yield shall
      mean the yield, as published in The Wall Street Journal on the day prior
      to the business day immediately prior to the closing date of each loan
      (or if such day is not a day on which The Wall Street Journal is
      published, then on the previous day), of the United States Treasury
      fixed rate security (i.e., a Treasury bond, note or bill, but excluding
      any such security (a) which can be surrendered at the option of the
      holder at face value in payment of any federal estate tax or (b) which
      provides tax benefits to the holder, other than withholding tax benefits
      for non-resident aliens or (c) which was issued at a discount) maturing
      in the same month and year as the loan.  In the event that more than one
      such security is listed, then the Treasury Yield shall equal the highest
      of such yields.  In the event that no such security is listed for such
      month, then the Treasury Yield shall equal the highest of the yields of
      such securities maturing in the month or months closest to such month.





5.    REPAYMENT
      Each loan shall be repayable in sixty (60) consecutive equal monthly
      installments of principal and interest, the first of said monthly
      installments being due and payable thirty (30) days following the
      closing date of such loan, and one on the same day of each and every
      month thereafter until all are fully paid.  Payments shall be applied
      first to interest upon the unpaid principal balance of the loan, and any
      amount remaining after payment of interest shall be applied in reduction
      of the principal.

6.    ADVANCES
      Borrower shall provide to CIT all invoices and checks for any Equipment
      that it has paid in full for and would like to have reimbursed.  Any
      Equipment that is being funded must be fully installed and accepted.
      There is a minimum loan amount of $250,000.00.

7.    DOCUMENTATION
      (a)   The loans will be evidenced and secured by a note and security
            agreement on the standard forms generally used by CIT.

      (b)   Borrower shall furnish to CIT UCC-1's and manufacturer's original
            invoices for each unit of Equipment.

      (c)   All loan documentation must be reviewed and approved (as to form
            and substance) by CIT and its counsel prior to closing.

8.    INSURANCE
      Borrower shall furnish to CIT a certified copy of an insurance policy
      in a minimum amount at least equal to the purchase price of all of the
      Equipment, insuring, against any loss to the Equipment by reason of
      collision, fire, theft and the other coverages usually afforded by an
      ACV endorsement, such policy of insurance to be in form and issued by
      a company reasonably satisfactory to CIT, containing such other
      endorsements as CIT may reasonably require (including, without
      limitation, an endorsement to the effect that the liability of the
      insurance company to CIT, as mortgagee, will not be diminished or
      impaired by any act or neglect of the Borrower), and with a long
      form loss payable endorsement in favor of CIT.

      All required policies of insurance (and any endorsements, renewals, or
      replacements thereof) shall contain the written obligation on the part
      of the insurance company to notify CIT at least thirty (30) days prior
      to any termination, cancellation, or material amendment of its policy,
      with opportunity by CIT to cure any nonpayment.

9.    PREPAYMENT
      Prepayment is allowed per Early Termination Table.

10.   COMMITMENT FEE AND APPLICATION OF CERTAIN PAYMENTS
      In consideration of CIT's commitment, the Borrower agrees to pay a
      Commitment Fee to CIT of Five Thousand Dollars ($5,000.00).  Said
      Commitment Fee is non-refundable whether or not the loan is closed for
      any reason whatsoever, except as provided in Paragraph 15 hereof.
      Borrower further expressly acknowledges that such Commitment Fee is fair
      and reasonable compensation for this commitment, considering the
      condition of the money market, the prevailing interest rates, the credit
      worthiness of the Borrower, the likelihood of the loan being made, the
      interest rate, and the other terms  contained herein.

      CIT acknowledges receipt from Borrower of two payments, $5,000.00 (in
      connection with the superseded commitment letter) and $15,000.00.  Of
      the total of these amounts, $5,000 will be applied as the above
      referenced Commitment Fee, and the remaining $15,000 will be held
      without interest and applied to the initial installments due in
      repayment of the loans.





11.   ADDITIONAL FEES (IF ANY)
      None.

12.   ADDITIONAL DOCUMENTATION
      In addition to the above-mentioned documentation, CIT shall be furnished,
      at or prior to closing (a) a current certificate of good standing, issued
      by the Secretary of State of Delaware, reflecting the good standing of
      Borrower in that state, (b) certified resolutions of Borrower authorizing
      the obtaining of the loan and designating the officer or officers to
      execute documents on behalf of the Borrower, and (c) such other
      information and documentation as CIT or its Counsel may reasonably
      require.

13.   CLOSING/EXPIRATION OF COMMITMENT
      All loans must close prior to the close of business on 12/31/95, when our
      commitment to make the loans shall expire and be of no further force and
      effect.

14.   CLOSING COSTS AND FEES
      None.

15.   CHANGE IN FINANCIAL CONDITION, CORPORATE STRUCTURE, BUSINESS PROSPECTS,
      ETC.
      If, in the reasonable judgment of CIT, there should occur, before the
      closing of the loan, any material adverse change in the financial
      condition or business prospects of the Borrower or any guarantor or any
      other party to whom CIT may have recourse, then, at the option of CIT,
      this commitment will become null and void.  We specifically call your
      attention to the fact that, in issuing this commitment, CIT is relying
      upon the financial statements delivered to us by the Borrower and any
      other party to whom CIT may have recourse, and the continuing maintenance
      of their respective present corporate structures and stock ownership.
      The Borrower shall be obligated to notify CIT of any material adverse
      changes in the financial condition, corporate structure, ownership or
      business prospects of any of the foregoing which occur between the date
      hereof and the date of closing of any of the loans.

      If we exercise our right to terminate this commitment because of our
      determination of material adverse change, we will refund the Commitment
      Fee and any of the $12,500 being held by CIT that has not already been
      applied to payments owing, less any and all expenses incurred or accrued
      in our processing of the contemplated loans.

16.   ASSIGNMENT
      This commitment may not be assigned without the prior written consent
      of CIT.

This commitment will only remain binding upon us if accepted by you and
returned so as to be received by us no later than May 12, 1995.

Should you have any questions regarding this commitment, please do not
hesitate to contact us.

Very truly yours,

THE CIT GROUP/EQUIPMENT FINANCING, INC.
