     b. A Promissory Note from Purchaser to Seller,  co-signed and guaranteed by
     RDB  in the  principal  amount  of  the  difference  between  the  combined
     outstanding  balances  of the SBA Loans  and the  Purchase  Price,  minus a
     credit of $100.00 to Purchaser for the proration of personal property taxes
     related  to the  Assets as set forth  below,  with  principal  and  accrued
     interest  payable  not later  than on the  first  anniversary  of  Closing.
     Interest  shall  accrue at a rate equal to the lowest  interest  rate being
     quoted on the Closing Date by Wachovia Bank, Charleston, South Carolina for
     short term, unsecured loans to its best customers plus one per cent (1%).

     Purchaser's and RDB's agreement  assuming the SBA Loans shall indemnify and
hold harmless Seller,  EVRM and Dr. and Mrs. Charles E. Feigley from any further
obligation or liability thereon. Purchaser shall make its best efforts to obtain
the  release  of  Seller  from its  liability  under  the SBA Loans as well as a
release of Dr. and Mrs.  Feigley and the  collateral  Dr. and Mrs.  Feigley have
pledged as security for the SBA Loans.  Seller will  cooperate with Purchaser in
this regard.

     1.03 Security Agreement.

     a. Pledge of Stock. The obligations of Purchaser and RDB under Section 1.02
     (a) and (b) above shall be secured by a first security  interest granted to
     EVRM in One Hundred Thousand (100,000) shares of EVRM common stock owned by
     RDB (the  "Shares"),  the  certificates  for which  shall be  delivered  at
     Closing to Seller with stock powers duly endorsed in blank by RDB.

     b. Pledge of Additional  Stock. If Seller,  Dr. and Mrs.  Feigley and their
     collateral  are not released from  liability  under the SBA loans by ninety
     (90) days after  Closing RDB will provide a first  security  interest in an
     additional Two Hundred  Thousand  (200,000) of such shares (the "Additional
     Shares") as  collateral  for EVRM's  security  interest.  At  Closing,  the
     certificate(s)  representing  the Additional  Shares with stock powers duly
     endorsed  in blank shall be  deposited  with a mutually  acceptable  escrow
     agent which will either return them to RDB upon such release of Seller, the
     Feigleys and their  collateral or deliver them to Seller at the  expiration
     of the ninety day period if such releases have not been obtained.

     c. RDB may notify EVRM at the end of any calendar quarter following Closing
     if the "bid"  price for EVRM  Common  Stock  for each  trading  day of such
     quarter on the OTC-BB or such  recognized  exchange on which the Shares and
     Additional Shares (collectively,  the "Pledged Securities") were traded was
     such that the  average of their  "bid"  prices on each day of such  quarter
     bore a ratio to the  combined  outstanding  balances  as of the last day of
     such quarter,  including accrued interest, of the SBA Loans (for which such
     releases have not been  obtained) and the  Promissory  Note provided for in
     Section 1.02 (b) above  (collectively,  the  "Outstanding  Loans Balance"),
     which was in excess of 3 to 2. Such  notice will  contain  such daily "bid"
     prices of the EVRM Common Stock and the  Outstanding  Loans Balance.  After
     verification  of the data  contained in such  notice,  EVRM will deliver an
     amount of the Pledged  Securities  to RDB having a value equal to (a) their
     average daily "bid" price for that quarter minus (b) the Outstanding  Loans
     Balance multiplied by the fraction, 3/2.

     d. At  Closing,  RDB shall  execute a security  agreement  in favor of EVRM
     containing the foregoing  terms, as well as such other terms and provisions
     as are usual and customary in such security and stock pledge  agreements in
     addition  to  a  UCC-1   Financing   Statement   containing  the  requisite
     information  regarding the security interest.  Such agreement shall provide
     that, absent a default therein or in the obligations which it secures,  RDB
     shall  retain his rights to all cash  dividends  and his rights to vote the
     Pledged  Securities  in  addition  to his right to execute  any  waivers or
     consents with respect thereto.

     1.04 Closing.  The Closing of this Agreement  shall be the  consummation of
all transactions  contemplated  hereby to be performed at Closing and shall take
place at 2:00 p.m. on April 26, 2000,  at the Premises or at such other time and
place as Seller  and  Purchaser  may  mutually  agree in writing  (the  "Closing

     1,000  square feet of office space in the Premises  (the  "Sublease")  on a
     week-to-week basis at a rental of One Hundred Seventy Dollars ($170.00) per
     week  commencing on the day of Closing and payable on the first day of each
     week  thereafter.  The Sublease  will be revocable by either party upon one
     week's notice to the other. Such rent and sublease shall be entirely net to
     EVRM which will have no responsibility whatever thereunder for any services
     to Purchaser except the provision of electricity, water and HVAC. Purchaser
     agrees  to be  responsible  for all  other  expenses  associated  with  the
     Sublease.

     b. Use of Certain  Telephone  Numbers.  Seller agrees to allow Purchaser to
     use existing Azimuth  telephone  numbers,  including the existing toll free
     telephone number, during the term of the Sublease. Purchaser will reimburse
     Seller for any costs incurred under such agreement. The parties acknowledge
     that the toll free number is currently in use by the Laboratory Business as
     are two of the local  numbers,  and  another  number is the main  corporate
     number for EVRM and is listed on its  10-K's.  At such time as EVRM and the
     Laboratory  Business no longer need their  telephone  and telefax  numbers,
     EVRM  will use its best  efforts  to  transfer  them to  Purchaser  as soon
     thereafter as practicable.  Any unrecovered  deposits will be reimbursed by
     Purchaser.  In the meantime,  should Purchaser so elect,  EVRM will use its
     best  efforts to transfer the number (843)  569-8792 to  Purchaser.  Should
     Purchaser terminate the sublease,  Seller agrees to transfer incoming calls
     for Purchaser to a number  provided to Seller and to provide such number to
     caller for future use.

     c. Release.  Effective  upon Closing,  Seller and EVRM forever  release and
     discharge  Purchaser  and RDB,  individually,  from and against any and all
     claims, demands, counterclaims,  actions, costs, causes of action, damages,
     debts,  obligations  and  liabilities of whatever nature arising out of the
     Employment  Agreement or out of RDB's  relationship with Seller and EVRM up
     to and including the date of this Agreement. This release is subject to the
     Closing of this Agreement.

     d. Noncompetition. For a period of Three (3) years following Closing within
     the State of South  Carolina,  neither  Seller nor EVRM shall,  directly or
     indirectly,  (i) engage in the  Industrial  Safety and  Hygiene  consulting
     business;  (ii) solicit in competition  with the Purchaser any Consultative
     Business  Clients  or  accept  Industrial  Safety  and  Hygiene  consulting
     business from any of them;  or (iii) without the consent of the  Purchaser,
     solicit  any  person  who is or has  been  employed  by  the  Purchaser  or
     encourage any such person to leave the employ of the Purchaser.

     e. Notwithstanding any provision herein to the contrary:

          (i) Nothing herein is intended,  nor shall it be deemed,  to impair or
          prevent  in  any  way  whatsoever   Seller's   continued,   unfettered
          engagement in the Laboratory  Business,  including the  performance of
          laboratory  services for  Consultative  Business  Clients.  Seller may
          continue to use the name "Azimuth Laboratories" in its conduct of such
          business.

          (ii)  Should  Seller  convey  all or  any  portion  of the  Laboratory

          Laboratories"  for a period of longer than six months from the Closing
          of such  transaction,  and it will make its best  efforts to acquire a
          noncompetitive  agreement from the  purchaser(s)  in such  transaction
          preventing  such  purchaser(s)  from competing  with the  Consultative
          Business.

     a. Sublease.  Purchaser agrees to abide by the terms of the sublease as set
     forth in Paragraph 3.01(a) above.

     has been  employed by either of them or encourage  any such person to leave

                                    AGREEMENT

     THIS AGREEMENT ( hereinafter  the  "Agreement") is made and entered into as
of the ___day of May, 2000, by and among AZIMUTH,  INCORPORATED  ("Azimuth"),  a
South Carolina corporation having its principal place of business in Charleston,
South Carolina;  ENVIROMETRICS, INC. ("EVRM"), a Delaware corporation having its
principal place of business in Charleston,  South Carolina, and sole shareholder
of Azimuth; and GAL Services,  Inc., a New York corporation having its principal
place of business in East Syracuse, New York ("GSI").

Background

     Azimuth is engaged,  inter alia, in the business of operating an Industrial
Safety and  Hygiene  laboratory  which  business  is  expressly  identified  and
segregated  as Azimuth's  Laboratory  Business  (the  "Laboratory  Business") on
Azimuth's internal financial statements; and,

     Azimuth desires to sell,  certain assets, and lease others, to GSI, and GSI
desires to purchase and lease the said assets from Azimuth, subject to the terms
and conditions herein.

Agreement

     In consideration of the mutual promises  contained below and for other good
and  valuable  consideration,  the  receipt and  sufficiency  of which is hereby
acknowledged, the parties hereby agree as follows:

ARTICLE I - PURCHASE AND SALE OF ASSETS

     1.01 The Sold Assets.  At Closing  Azimuth  hereby agrees to sell,  convey,
transfer,  assign,  set over and deliver to GSI,  and GSI agrees to purchase and
accept, the following assets (the "Sold Assets"):

     a.  The  list of  current  and  former  Laboratory  Business  clients  (the
     "Laboratory Business Clients") attached hereto as Exhibit "A";

     b. A license to use the name "Azimuth  Laboratories"  for so long as may be
     necessary  to effect  an  orderly  transition  of the  Laboratory  Business
     Clients  but not longer than six months from  Closing,  provided  that such
     license is  non-exclusive  to the extent that the use of the name "Azimuth"
     may be used by Azimuth's consultative business so long as such use does not
     include the term  "Laboratory" or "Laboratories";  and,  provided further,
     that  Azimuth  shall be  permitted  to  retain  the name  "Azimuth"  as its
     corporate  name so long as it adheres  to the  provisions  below  regarding
     noncompetition with GSI;

     c. Those  outstanding  assignments  from Laboratory  Business  Clients upon
     which work has begun but which remain unfinished and uninvoiced at Closing,
     if any ("Work in Process")  provided  that none of the Work in Process will
     have been  received by Azimuth  more than Seven days prior to closing.  GSI
     agrees to assume Azimuth's remaining obligations under such assignments;

     d. All records and files in Azimuth's  possession  of  Laboratory  Business
     Clients which have given Azimuth  written  instructions  to release same to
     GSI  (except  that  records  and  files  relating  to Work in  Process  and
     proposals outstanding at Closing will be delivered to GSI at Closing).  GSI
     will keep and maintain such records and files in safekeeping  and make them
     available to Azimuth to the extent Azimuth, or Azimuth's parent,  successor
     or insurance company may require same to respond to future claims.

     No assets which are not explicitly described above are included in the Sold
Assets, and specifically  excluded are Azimuth's  consultative  business and the
assets,  clients,  records  and  business  related  thereto  (collectively,  the
"Consultative Business"). It is acknowledged by Azimuth that GSI is not assuming
any  liability of Azimuth  other than that  expressly  described in Section 1.01
(c).

     1.02 Purchase Price.  The purchase price for the Sold Assets (the "Purchase
Price") shall consist of Twenty-five Thousand Dollars  ($25,000.00),  payable at
Closing.

     1.03  Allocation of Purchase  Price.  The Purchase  Price will be allocated
among the various  Assets as GSI, in its  discretion,  may elect,  in conformity
with GAAP.

     1.05 Closing.  The Closing of this Agreement  shall be the  consummation of
all transactions  contemplated  hereby to be performed at Closing and shall take
place at the  offices of Azimuth or at such other  place as Azimuth  and GSI may
mutually  agree in writing  either (a)  within  two  business  days of notice by
Azimuth to GSI of its  readiness to close within two  business  days,  or (b) at
12:00  Noon May 8,  2000,  whichever  is  sooner.  GSI will  have  access to the
Laboratory facilities for 7 days after Closing to remove any Leased Assets.

The  obligation  of GSI to  close  this  transaction  is  conditioned  upon  the
following:

     (a) the  representations  and warranties set forth in Section 3.01 shall be
     true and correct in all material respects at and as of the Closing Date;

     (b) Azimuth  shall have  performed  and complied  with all of its covenants
     hereunder in all material respects through the Closing.

ARTICLE II - LEASE OF ASSETS

     At Closing, Azimuth hereby agrees to lease to GSI, and GSI hereby agrees to
rent from Azimuth, all of the equipment described in Exhibit "B" attached hereto
(the "Leased Assets") upon the following terms and conditions:

     2.01 Rent.  The rent (the  "Rent")  which GSI shall pay to Azimuth  for the
Leased Assets shall consist of, and be payable according to, the following:

     a. Base  Rent,  which  shall be Ten  percent  (10%) of all  Gross  Revenues
     received by GSI from Laboratory Business Clients during the first two years
     following  Closing except as set forth below. The Base Rent will be paid on
     the 15th day of each month  following GSI's receipt of payment from clients
     on the  applicable  revenues.  "Gross  Revenues"  shall be exclusive of any
     deductions for taxes or any other charges other than costs  associated with
     subcontracted  analytical work. GSI shall use its  commercially  reasonable
     efforts to acquire the  business of  Laboratory  Business  Clients and will
     perform  its  obligations  to them  on a  timely  basis  with a  degree  of
     professionalism  and skill that meets generally  accepted  standards of the
     industry.  Such  standards  will not  obligate GSI to maintain an office in
     South Carolina.  Azimuth shall assist GSI in the notification of Laboratory
     Business Clients of the transaction  contemplated hereby. GSI's obligations
     to pay Base Rent shall terminate if and when the Base Rent paid into escrow
     (as  provided  below) and to Azimuth  cumulatively  (the  "Cumulative  Base
     Rent") equals Forty Thousand  Dollars  ($40,000.00) per year during each of
     the two years  following  the Closing  Date. If at the end of such two year
     period the Cumulative Base Rent is less than $30,000.00, GSI shall continue
     to pay into escrow  and/or to Azimuth,  as required by Section  2.02 below,
     ten  percent  (10%) of Gross  Revenue  received  from  Laboratory  Business
     Clients  over the five  years  following  such two year  period  until such
     Cumulative Base Rent equals $30,000.00.  If the Cumulative Base Rent at the
     end of such seven years is less than $30,000 (the "Minimum Base Rent"), GSI
     shall pay the  difference  between the Minimum Base Rent and the Cumulative
     Base Rent into escrow and/or to Azimuth, as required by Section 2.02 below,
     in one  lump sum  payment  at that  time,  unless  the  Minimum  Base  Rent
     requirement has been eliminated as provided in Section 2.02 below.

     b. Additional  Rent,  consisting of (i) twenty-five per cent (25%) of Gross
     Revenues  received by GSI on non-Lead analysis Work in Process and (ii) ten
     per cent (10%) of Gross  Revenues  received by GSI on Lead analysis Work in
     Process, both payable monthly as above.

     2.02 Liens.  The parties  acknowledge that the Leased Assets are subject to
security  interests of the U. S. Small  Business  Administration  (the  "Liens")
evidenced by UCC 1 Financing  Statements ## 90-026761,  continued at 95-0217 and
90-026762, continued at 95-0217 on file with the Secretary of State of the State
of South Carolina.  Notwithstanding  anything to the contrary herein, so long as
the Liens are  outstanding,  GSI will pay all Rent into escrow with the law firm
of Wood and Smith, P.C., Syracure,  New York as escrow agent. If a proceeding is
commenced to foreclose either or both of the Liens, Azimuth shall be required to
offer to the lienholder,  prior to the seizure of any of the Leased Assets,  all
of the funds  then in the escrow  account,  up to a maximum  of  $35,000.00,  in
exchange for termination of the Liens. If the lienholder  refuses such offer and
seizes  the  Leased  Assets and the funds then in escrow are equal to or greater
than $35,000.00,  then the escrow will terminate,  and: (a) GSI will receive the
first  $35,000.00 of the escrowed  funds;  (b) Azimuth will receive the balance;
(c) thereafter,  Rent will be paid directly to Azimuth according to the terms of
Section 2.01 above.  If the lienholder  refuses such offer and seizes the Leased
Assets and the funds then in escrow  are less than  $35,000.00,  then the escrow
will terminate, and: (a) GSI will receive all of the escrowed funds; (b) ensuing
Rent will  accrue to the  account of GSI until it,  together  with the  escrowed
funds paid to GSI, equals  $35,000.00;  and, (c)  thereafter,  Rent will be paid
directly to Azimuth  according to the terms of Section  2.01 above;  except that
(d) the Minimum Base Rent requirement will be extinguished.

     Upon  termination  of the Liens,  at GSI's  election,  (a) the lease of the
Leased  Assets  provided for herein shall remain in effect until the last rental
payment due thereunder,  upon which title to the Leased Assets will pass to GSI;
or, (b) title to the Leased Assets will  thereupon  pass to GSI upon its payment
of $1.00 to Azimuth,  and all  ensuing  rental  payments to Azimuth  will become
referral  fees.  At Closing,  Azimuth will deposit a Bill of Sale for the Leased
Assets in the form  attached  hereto as Exhibit C which will be  released to GSI
when title to the Leased Assets passes to GSI.

     2.03 Condition of Assets;  Net Lease.  The Leased Assets are leased "as is"
and "where  is," and  Seller  makes no  express  or  implied  representation  or
warranty  whatever in regard  thereto,  including  warranty of  merchantability,
fitness for a particular  purpose or any other warranty of any nature, all which
are hereby expressly disclaimed by Seller to the extent permitted by the laws of
the State of South Carolina.  The lease of the Leased Assets shall be absolutely
net to Azimuth. Any expenses in connection with the Leased Assets, including all
maintenance,  repairs,  taxes (except year 2000 ad valorem taxes as set forth in
Section 3.01 below) and insurance,  and there shall be no deduction or setoff of
any nature against the Rent except as may be expressly set forth herein.

     2.04 Security  Agreement.  The obligations of GSI hereunder will be secured
by a first security interest in the accounts receivable from Laboratory Business
Clients and the  proceeds  therefrom.  At  Closing,  Purchaser  shall  execute a
security  agreement in favor of EVRM containing the foregoing  terms, as well as
such other terms and  provisions  as are usual and  customary  in such  security
agreements in addition to a UCC-1 Financing  Statement  containing the requisite
information regarding the security interest.
