1.   THE LOANS
REVOLVING CREDIT NOTE 1.1.  Subject to the terms and conditions hereof, Bank
agrees to make loans ("LOAN" or "LOANS") to Borrowers from time to time before
the Termination Date, not to exceed at any one time outstanding the lesser of
the Borrowing Base or $6,000,000.00 ("COMMITMENT").  Borrowers may borrow, repay
and reborrow upon a Loan Request in Proper Form submitted by either Borrower.
Loans may only be used to (i) pay off amounts payable under the Old Facilities,
and, thereafter, (ii) finance accounts receivable and inventory from Borrowers'
regular business operations.  Chapter 15 of the Texas Credit Code will not appy
to this Agreement, the Note or any Loan.  The Loans will be evidenced by, and
will bear interest and be payable as provided in, Borrowers' promissory note
dated the Effective Date (together with any and all renewals, extensions,
modifications and replacements thereof and substitutions therefor, the "NOTE").
"TERMINATION DATE" means the earlier of:  (a) June 30, 1998; or (b) the date
specified by Bank pursuant to SECTION 6.1 hereof.

LETTERS OF CREDIT 1.1.A  Bank in its sole absolute discretion may issue sight
draft commercial and/or standby letters of credit up to the day before the
Termination Date for the account of Borrowers and in favor of such Person or
Persons as may be designated by either Borrower upon an application
substantially in the form of Bank's then current application and agreement
therefor or other application acceptable to Bank ("APPLICATION"), duly completed
and executed by either Borrower in Proper Form not less than two (2) Business
Day(s) prior to the date on which the letter of credit is to be issued.  "LETTER
OF CREDIT" means any Letter of Credit issued by Bank upon an Application of
Borrowers.  No Letter of Credit shall have an expiry date later than a date
______ months from the Termination Date.  Letters of Credit may be commercial or
standby.  "L/C OBLIGATIONS" means the sum of (a) the face amount of all
outstanding Letters of Credit less any drawings that have been paid by Borrowers
either with a


                                        2


Loan or other means acceptable to Bank and (b) any other amounts owing to Bank
under the Applications not already included in (a).  Borrowers will pay a fee in
an amount equal to the greater of: (a) (i) for commercial L/Cs, one percent
(1.0%) per quarter or fraction thereof on the face amount of the Letter of
Credit and (ii) for Standby L/Cs, three percent (3.0%) per annum or fraction
thereof on the face amount of the Letter of Credit; and (b) Bank's minimum fee
in effect on the issue date of the Letter of Credit.  Bank may at any time, but
is not required to, make a Loan without prior notice to Borrowers to pay any
drawing under a Letter of Credit and to pay any L/C Obligation.  Letters of
Credit shall be for the purpose of financing trade credit extended to either
Borrower in its regular course of business.  L/C Obligations shall never exceed
$2,000,000.00 ("LETTER OF CREDIT SUBLIMIT").

BORROWING BASE 1.2:

(a)  The BORROWING BASE on each Business Day is the "Total Availability on
     Accounts Receivable and Inventory" calculated in accordance with the
     Borrowing Base Certificate in Exhibit A, the "Accounts Receivable Loan
     Administration Procedures" delivered by Bank to Borrower and incorporated
     herein by reference as if fully set forth.  Each reference to "Chase
     Manhattan Bank" in Exhibit A shall be deemed a reference to Bank.  The
     Borrowing Base shall include only Accounts receivable of 1st Tech.
(b)  The calculations, definitions and other criteria set out in Exhibit A shall
     be subject to the following definitions and adjustments:
        (i)    "Other" ineligible Accounts means all Accounts not subject to
        Bank's first  and prior lien and security interest and such assets
        deemed from time to time to be, in the sole judgment of the Bank,
        ineligible for purposes of determining the Borrowing Base; Memo A/R and
        Evaluation A/R shall be Ineligible Accounts.  "'Memo' and 'Evaluation'
        A/R" shall include all Accounts of the type typically referred to as
        such by Borrower prior to the Effective Date, and any accounts which do
        not represent payments finally earned or which result from a sale
        subject to product evaluation by the buyer.  Outstanding Loans, interest
        and fees counted against Total Availability on Accounts Receivable and
        Inventory shall use Bank's standard estimation provided by Bank to
        Borrower.
        (ii)   Each Accounts Advance Factor may be increased or decreased by the
        Bank at any time and from time to time upon written notice to Borrower,
        in the reasonable exercise of Bank's sole underwriting discretion.
        Without limiting the generality of the foregoing, Bank shall be deemed
        to have exercised reasonable discretion if it reduces the Accounts
        Advance Factor in reasonable proportion to increased dilution of
        Accounts which Bank believed exceeds 5% of the amount existing at the
        Effective Date of the Agreement.

REQUIRED PAYMENT 1.3  If the unpaid amount of the Loans and L/C Obligations on
any Business Day exceeds the Borrowing Base on such day, Borrowers shall make a
payment on the Note in an amount sufficient to reduce the total unpaid principal
balance of the Note to an amount no greater than the Borrowing Base, such
payment due and payable on the date such excess occurs, to accompany timely
delivery of Borrowers' monthly Borrowing Base Report or Daily Collateral
Certificate, as the case may be.  If the balance on the Note is zero and the


                                        3


amount of L/C Obligations still exceeds the Borrowing Base, Borrowers will
promptly deliver cash collateral to Bank in an amount sufficient to eliminate
such excess.

FACILITY FEES 1.4  Borrowers will pay the following fees: (i) a Structuring Fee
of $75,000.00, due and payable upon the execution of this Agreement; and (ii) an
Administration Fee of $50,000 per annum payable in installments due on the
Effective Date of this Agreement and the 1st date of each third month
thereafter.  Borrowers authorize Bank in its discretion and without prior notice
to advance against the Commitment and Note to pay these fees when due.

PAST DUE AMOUNTS 1.5  Each amount due to Bank in connection with the Loan
Documents will bear interest from its due date until paid at the Highest Lawful
Rate unless the applicable Loan Document provides otherwise.

2.   CONDITIONS PRECEDENT.
ALL LOANS AND L/C OBLIGATIONS 2.1  Bank is not obligated to make any Loan

and each Subsidiary of each Borrower is in compliance with all applicable Legal
Requirements and manages and operates (and will continue to manage and operate)
its business in accordance with good industry practices.  No Borrower or
Subsidiary of any Borrower is in default in the payment of any other
indebtedness or under any agreement to which it is a party.  The Parties have
obtained all consents of and registered with all Governmental Authorities or
other Persons required to execute, deliver and perform the Loan Documents.

LITIGATION 3.5  Except as previously disclosed to Bank in writing, there is no

affecting any Borrower or Subsidiary of any Borrower before or by any
Governmental Authority.

been obtained and are in full force and effect.

and not primarily for personal, family, or household use or primarily for
agricultural purposes as such terms are used in Chapter One of the Texas Credit

substance, on or off its premises (whether or not owned by any of them).  No
Borrower or Subsidiary of any Borrower has any material contingent liability for
non-compliance with environmental or hazardous waste laws.  No Borrower or

between the terms of this Agreement and the Lockbox Processing Agreement or the
Terms and Conditions of the Collection Account, the terms of this Agreement
shall govern; (iii) Deliver, or cause to be delivered, directly to the Bank for

segregated from other funds of such Borrower and paid over to Bank in same form
as received with any endorsement to be held in the Collection Account.  Bank

invoice or bill of lading related to any Collateral; (b) after the occurrence of
an Event of Default which is continuing, to notify the U.S. Postal Service and
any other person to change address for delivery of any Borrower's mail to such
address as may be designated by Bank; and (c) to do all such other acts and
things in the name of Borrower


                                        8

provisions of this section 4.10.  This power of attorney is irrevocable, shall
survive the dissolution or liquidation of such Borrower, and is deemed coupled
with an interest.  This power of attorney shall terminate only at such time as
all Obligations have been paid in full.  Termination of the power of attorney
shall not affect the validity of any acts performed by the Bank pursuant to the
power of attorney prior to termination.  This power of attorney evidences rights
which are cumulative with all other rights granted in all other Loan Documents,
and is entitled in all respects to the indemnity appearing in section 7.8.  D.
GRANT OF SECURITY INTEREST.  Each Borrower assigns and pledges to Bank, and
grants to Bank a security interest in, all of such Borrower's right, title and
interest in and to the Collection Account, and all certificates and instruments,

SURVIVAL; PARTIES BOUND; TERM OF AGREEMENT 7.5  (a) All representations,
warranties, covenants and agreements made by or on behalf of each Borrower in
connection with


                                       13


the Loan Documents will survive the execution and delivery of the Loan
Documents; will not be affected by any investigation made by any Person, and
will bind Borrower and the successors, trustees, receivers and assigns of each
Borrower and will benefit the successors and assigns of Bank; PROVIDED that
Bank's agreement to make Loans to Borrowers will not inure to the benefit of any
successor or assign of any Borrower.  Except as otherwise provided herein, the
term of this Agreement will be until the later of the final maturity of the Note
and the full and final payment of all Obligations and all amounts due under the
Loan Documents.  (b) Borrowers shall be entitled to terminate the Commitment by
written notice to Bank, which notice shall become effective as to the accrual of
fees payable hereunder upon the happening of the latest of (i) 30 days after
Bank's receipt of such notice; and (ii) repayment in full of all amounts
outstanding under the Note and otherwise under the Agreement.

DOCUMENTARY MATTERS 7.6  This Agreement may be executed in several identical
counterparts, on separate counterparts; each counterpart will constitute an
original instrument, and all separate counterparts will constitute but one and
the same instrument.  The headings and captions in the Loan Documents have been
included solely for convenience and should not be considered in construing the
Loan Documents.  If any provision of any Loan Document is invalid, illegal or
unenforceable in any respect under any applicable law, the remaining provisions
will remain effective.  The Loans and L/C Obligations and all other obligations
and indebtedness of Borrower to Bank are entitled to the benefit of the Loan
Documents.

EXPENSES AND FEES 7.7  Any provision to the contrary notwithstanding, and
whether or not the transactions contemplated by this Agreement are consummated,
Borrowers agree to pay on demand all out-of-pocket expenses (including, without
limitation, the fees and expenses of counsel for Bank) in servicing and
collection of the Loans and L/C Obligations.  Borrower agrees to pay Bank's
standard (i) Documentation Preparation and Processing Fee for preparation,
negotiation and handling of this Agreement; (ii) lockbox processing fees as
provided for in the separate agreement therefor; (iii) account maintenance fees
for the Collection Account; (iv) any expenses of collection or other expenses
incurred by Bank in connection with the maintenance of the Collection Account,
shall be reimbursed by Borrowers to Bank at customary fee rates charged by the
Bank for the services.  In consideration of Bank's services of collecting the
Accounts hereunder and monitoring and examining the Borrowing Base, Borrowers
agree to pay Bank the Administration Fee provided for in Section 1.4.  Bank may
obtain reimbursement by causing other depository accounts of either Borrower at
Bank to be charged from time to time therefor.  The obligations of Borrowers
under this and the following section will survive the termination of this
Agreement but the accrual of periodic fees accrued during the existence of the
Commitment shall be subject to the termination provisions in Section 7.4.  Each
Borrower authorizes Bank in its discretion and without prior notice to advance
against the Commitment and Note to pay any or all such fees, expenses and other
such Obligations when due.

INDEMNIFICATION 7.8  Each Borrower agrees to indemnify, defend and hold Bank
harmless from and against any and all loss, liability, obligation, damage,
penalty, judgment, claim, deficiency and expense (including interest, penalties,
attorneys' fees and amounts paid in settlement) to which Bank may become subject
arising out of or based upon the Loan Documents, any Loan, or the receipt,
handling, payment and application of the monies received


                                       14


in connection with the Collection Account, including that resulting from Bank's
own negligence, EXCEPT and to the extent caused by Bank's gross negligence or
willful misconduct.

USURY NOT INTENDED 7.9  Borrowers and Banks intend to conform strictly to
applicable usury laws.  Therefore, the total amount of interest (as defined
under applicable law) contracted for, charged or collected under this Agreement
or any other Loan Document will never exceed the Highest Lawful Rate.  If Bank
contracts for, charges or receives any excess interest, it will be deemed a
mistake.  Bank will automatically reform the Loan Document or charge to conform
to applicable law, and if excess interest has been received, Bank will either
refund the excess to Borrowers or credit the excess on any unpaid principal
amount of the Note or any other Loan Document.  All amounts constituting
interest will be spread throughout the full term of the Loan Document or
applicable Note in determining whether interest exceeds lawful amounts.

RIGHTS OF BORROWER AND BANK 7.10  Bank has not exercised any control, and Bank
shall not exercise any control, over Borrowers in the determination of which of
Borrowers' creditors Borrower will pay or which payments any Borrower will make
in the ordinary course of any Borrower's business.  Each Borrower, alone, shall
exercise such judgment and determination.  Nothing contained herein, however,
shall, in any manner, affect, limit or impair the rights or remedies of Bank
under this Agreement or any other Loan Documents as otherwise provided by
applicable law, whether with regard to realization on the Collateral, rights of
set off, compensation or otherwise.

PARTICIPATION; SETOFF 7.11  Borrowers and Bank acknowledge and agree that Bank,
in Bank's sole discretion, may assign its interest or sell participation(s) in
the Loans and Note to third parties, including without limitation Texas
Commerce, without consent of or notice to Borrowers.  Borrowers and Bank agree
that each such participant shall be treated, to the extent of its pro rata
interest in Borrowers' indebtedness, as if it were a party thereto, and shall be
accorded and is hereby granted the right to setoff against any deposits, credit
balances, or other funds of each Borrower which are or may be in its possession
(without regard to maturity, tenor or other elements of otherwise mutual
indebtedness).

NO COURSE OF DEALING 7.9  NO COURSE OF DEALING BY ANY BORROWER WITH BANK, NO
COURSE OF PERFORMANCE AND NO TRADE PRACTICES OR OTHER EXTRINSIC EVIDENCE OF ANY
NATURE MAY BE USED TO CONTRADICT, VARY, SUPPLEMENT OR MODIFY ANY TERM OF THIS
AGREEMENT.

                       FIRST AMENDMENT TO CREDIT AGREEMENT

THIS FIRST AMENDMENT TO CREDIT AGREEMENT ("Amendment" or First Amendment") dated
as of November 14, 1996 ("Effective Date"), is between 1ST TECH CORPORATION
("1st Tech"), a Delaware corporation, DARKHORSE SYSTEMS, INCORPORATED
("Darkhorse"), a Delaware corporation (jointly and severally, "Borrowers" and
each a "Borrower"); TANISYS TECHNOLOGY, INC., a Wyoming corporation
("Guarantor") and THE CHASE MANHATTAN BANK, a New York state bank, successor by
merger of Chemical Bank ("BANK").

PRELIMINARY STATEMENT.  Borrowers and Bank entered into a Credit Agreement dated
as of May 20, 1996 (as amended by this and prior amendments, "Credit Agreement"
or "Agreement").  In this Amendment, all capitalized terms defined in the Credit
Agreement and not otherwise defined herein have the same meanings as in the
Credit Agreement, and each Section, Exhibit and similar reference is to the
Credit Agreement as amended.  Borrowers and Bank have agreed to amend the Credit
Agreement to the extent set forth herein, and in order to, among other things,
modify certain financial covenants, provide for waivers of certain prior period
defaults, and modify the Borrowing Base to include certain receivables of
Darkhorse.

NOW THEREFORE, in consideration of the premises and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged by
the parties, Borrowers and Bank agree as follows:

1.   The last sentence of Section 1.2(a) is amended to read:  "The Borrowing
Base shall include Accounts of both Borrowers."

2.   Exhibit B is replaced with Exhibit B attached to this Amendment.  The
Borrowing Base certificate included in Exhibit A is replaced with the Borrowing
Base Certificate attached to this Amendment.

3.   Limited Waivers.  Borrowers have reported that as of August 31, 1996 and
September 30, 1996 the Tangible Net Worth of 1st Tech is below the amount agreed
to in the Agreement.  Borrowers have requested and Bank has agreed to waive the
foregoing prior period default, for the specific instances described for those
prior periods only, subject to the terms of this waiver provision.  This waiver
is subject to the conditions and understandings of Borrowers that: (i) no other
waivers are promised by the Bank; (ii) Bank understands the requested waivers to
address all defaults as to covenants, representations and warranties known to
Borrowers as of the Date of this Amendment, Borrowers having represented that in
all other respects no Event of Default has occurred and is continuing; (iii)
Borrowers will not in any way rely upon the any future waiver of any default;
and (iv) any future delay or election not to exercise rights by the Bank shall
not be deemed any waiver of rights.  Bank's rights in the event of a default are
set out in the Agreement, Note and the other Loan Documents.  This provision is
the only evidence of Bank's waiver.

4.   Confirmation of Security Interests.  No security interest, lien, or other
interest granted by Borrowers, any guarantor or other person to Bank is released
or limited in connection with the 



execution of this Amendment.  Borrowers confirm and ratify each of the liens, 
security interests and other interests granted in each and all security 
agreements executed in connection with, related to, or securing the Credit 
Agreement, each prior amendment and each note and loan heretofore governed by 
the Credit Agreement, each in accordance with its stated terms.  Borrowers 
represent and warrant that each guaranty executed in connection with, related 
to, or securing the Credit Agreement, each prior amendment and each note and 
loan heretofore governed by the Credit Agreement, each in accordance with its 
stated terms.  Borrowers represent and warrant that each guaranty executed in 
connection with, related to, or securing the Credit Agreement, each prior 
amendment and each note and loan heretofore governed by the Credit Agreement, 
remains in force as of the Effective Date of this Amendment, in accordance 
with its stated terms.

5.   Borrowers represent and warrant to Bank that after giving effect to this
Amendment that the representations and warranties set forth in the Credit
Agreement are true and correct on the date hereof as though made on and as of
such date.  Each of the other Loan Documents is in all other respects ratified
and confirmed, and all of the rights, powers and privileges created thereby or
thereunder are ratified, extended, carried forward and remain in full force and
effect except as the Credit Agreement is amended by this Amendment.

6    This Amendment shall become effective as of its Effective Date upon
execution and delivery by each of the parties named in the signature lines
below, and "Agreement" and "Credit Agreement" as used in the Credit Agreement
and this Amendment shall refer to the Credit Agreement as amended by this
Amendment.  This Amendment shall be included within the definition of "Loan
Documents" as used in the Agreement.  This Amendment may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed shall be deemed an original and all of which
taken together shall constitute but one and the same agreement.

7.   THIS AMENDMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD TO CONFLICT OF LAW PRINCIPLES);
PROVIDED THAT THE BANK SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

THIS WRITTEN AMENDMENT AND THE OTHER LOAN DOCUMENTS CONSTITUTE ALL "LOAN
AGREEMENT" AS DEFINED IN SECTION 26.02(a) OF THE TEXAS BUSINESS AND COMMERCE
CODE, AND REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS
OF THE PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.


                                        2
