Exhibit 10.3



                       FIRST AMENDMENT TO CREDIT AGREEMENT

         This FIRST AMENDMENT TO CREDIT  AGREEMENT  (this "First  Amendment") is
entered into as of February 4, 1999, by and between APPLIED CELLULAR TECHNOLOGY,
INC., a Missouri  corporation  (together with its  successors  and assigns,  the
"Borrower") and (b) STATE STREET BANK AND TRUST COMPANY,  a Massachusetts  trust
company (together with its successors and assigns, the "Bank").

         All  capitalized  terms not defined  herein but defined in that certain
Credit  Agreement,  dated as of August 25, 1998, by and between the Borrower and
the Bank  (as the  same  may be  amended,  modified,  substituted,  extended  or
restated,  from time to time,  the "Credit  Agreement")  shall have the meanings
given to such terms in the Credit Agreement.

                             Preliminary Statements:

         A. Pursuant to the terms and conditions of the Credit Agreement and the
other Credit  Documents,  the Bank has  established a certain  Revolving  Credit
Facility  (the  "Revolving  Credit  Facility")  in favor of the  Borrower in the
original   principal   amount  of  up  to  Twenty  Million  and  00/100  Dollars
($20,000,000.00); and

         B. On or about October 7, 1998, the Borrower  created Applied  Cellular
Technology  Financial  Corp.,  a  New  Hampshire  corporation,  which  is a  new
wholly-owned Subsidiary of the Borrower (the "New Subsidiary"); and

         C. Section 5.18 of the Credit  Agreement  requires that,  within thirty
(30) days after the creation of any new Subsidiary,  the Borrower cause such new
Subsidiary to become a Guarantor of the  Obligations by executing and delivering
certain  agreements,  documents  and  instruments  which  are more  particularly
described therein; and

         D. The Borrower now requests  that (i) the Bank  increase the aggregate
principal  amount  available  under the  Revolving  Credit  Facility from Twenty
Million and 00/100 Dollars  ($20,000,000.00)  to Twenty Three Million and 00/100
Dollars  ($23,000,000.00);  and (ii) extend the date by which the New Subsidiary
must become a Guarantor to March 31, 1999; and

         E. The Bank is not willing to (i) so increase the  aggregate  principal
amount  available under the Revolving Credit Facility or (ii) extend the date by
which the New Subsidiary must become a Guarantor,  unless and until the Borrower
has  entered  into and agreed to all of the terms and  conditions  of this First
Amendment;

         NOW, THEREFORE, in consideration of the mutual agreements and covenants
contained herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby  acknowledged,  the Borrower and the Bank hereby
agree as follows:

         1.       Amendments to Credit Agreement.

                  1.1  Amendment  to Section  1.01.  The  definition  of "Credit
         Documents"  contained in Section 1.01 of the Credit Amendment is hereby
         amended, restated and superseded in its entirety as follows:





                           "'Credit  Documents'  shall mean this Agreement,  the
                  Note, the Guaranty  Agreement,  the Security Documents and any
                  and all other agreements, guaranties,  instruments, documents,
                  certificates,   financing  statements,   powers  of  attorney,
                  consents and filings,  whether  heretofore,  now, or hereafter
                  executed by or on behalf of the Borrower, any Guarantor or any
                  other Person and delivered to the Bank in connection  with the
                  Credit,  all  as  may  be  amended,  modified,   supplemented,
                  restated or extended, from time to time."

               1.2  Amendment to Section  2.01(a).  The  reference  contained in
          Section 2.01(a) of the Loan Agreement to  "$20,000,000" is deleted and
          replaced with the following: "Twenty- Three Million and 00/100 Dollars
          ($23,000,000.00)".

               1.3  Amendment to Section  2.01(b).  The  reference  contained in
          Section 2.01(b) of the Loan Agreement to  "$20,000,000" is deleted and
          replaced with the following: "Twenty- Three Million and 00/100 Dollars
          ($23,000,000.00)".

         2. First Allonge to Revolving  Credit Note.  The Borrower shall execute
and deliver  contemporaneously  herewith to the Bank a certain  First Allonge to
Revolving  Credit Note (the "First  Allonge to  Revolving  Credit  Note") by and
between the  Borrower  and the Bank which  amends the  Revolving  Credit Note to
reflect the  increase in the  aggregate  principal  amount  available  under the
Revolving   Credit   Facility   from   Twenty   Million   and   00/100   Dollars
($20,000,000.00)  to Twenty Three Million and 00/100  Dollars  ($23,000,000.00).
The First Allonge to Revolving  Credit Note shall be  substantially  in the form
attached hereto as Exhibit A and incorporated herein by reference.

         3.  Reaffirmation  of Guaranty  Agreement and Security  Documents.  The
Borrower  shall cause the  Guarantors  to execute and deliver  contemporaneously
herewith to the Bank a certain  Reaffirmation of Guaranty Agreement and Security
Documents (the "Reaffirmation of Guaranty Agreement and Security  Documents") by
and between the  Borrower  and the  Guarantors,  pursuant to which,  among other
things,  each of the Guarantors  reaffirms all of its  obligations and liability
under the Guaranty  Agreement  and each of the Security  Documents to which each
such Guarantor is a party. The Reaffirmation of Guaranty  Agreement and Security
Documents  shall be  substantially  in the form attached hereto as Exhibit B and
incorporated herein by reference.

         4. New  Subsidiary  -  Extension.  The Bank hereby  extends the date by
which the New  Subsidiary  must become a Guarantor to March 31, 1999, so long as
by such date the Borrower  shall have complied with all of the  requirements  of
Section 5.18 of the Credit Agreement with respect to such New Subsidiary.

         5 Ratification of Credit Documents. Subject to the amendments expressly
set forth in Section 1 above and in the First Allonge to Revolving  Credit Note,
the Borrower  hereby  ratifies and reaffirms all of the terms and  provisions of
the Credit  Agreement  and all of the other  Credit  Documents  to which it is a
party or by which it or its property is bound, and hereby expressly acknowledges
and confirms that the terms and provisions of each thereof,  as amended  hereby,
shall and do remain in full force and effect, without change.

                                       2




         6. Representations and Warranties. The Borrower hereby acknowledges and
confirms that all of its representations and warranties  contained in the Credit
Agreement and in all of the other Credit Documents are and remain true,  correct
and  complete as of the date hereof as if made as of the date hereof  (except as
the same may  expressly  relate to an earlier  date,  and except as the same may
relate or apply to the New Subsidiary).  The Borrower represents and warrants to
the Bank that if, effective as of the date hereof,  the New Subsidiary was to be
party to the Guaranty  Agreement and the other Credit  Documents to which all of
the other Guarantors are parties, there would be no breach by the New Subsidiary
of any of the representations and warranties  contained therein which would have
a material and adverse effect on the Borrower and the Guarantors  (including the
New  Subsidiary),  when  taken  as a  whole,  and  there  would  be  no  events,
circumstances  or  conditions  (financial  or  otherwise)  relating  to the  New
Subsidiary,  which would  materially and adversely impair the ability of the New
Subsidiary to perform or observe all of its respective  obligations  thereunder,
in accordance with the terms thereof.

         7. No Events of Default. The Borrower hereby represents and warrants to
the Bank that no Event of Default or Default has occurred and is now  continuing
under the Credit Agreement or under any of the other Credit Documents, and there
does not now exist any  circumstance or set of facts,  which with the passage of
time or the giving of notice or both would  constitute  or result in an Event of
Default or a default under the Credit Agreement or under any of the other Credit
Documents.

         8. Conditions  Precedent.  The obligations of the Bank under this First
Amendment are subject to the  satisfaction  of each of the following  conditions
