                             DEMAND PROMISSORY NOTE

     FOR VALUE RECEIVED, the undersigned, AVATECH SOLUTIONS SUBSIDIARY, INC., a
Delaware corporation ("BORROWER"), promises to pay to the order of KEY BANK AND
TRUST ("LENDER"), at the LENDER'S offices at 7F Gwynns Mill Court, Owings Mills,
Maryland 21117, or at such other places as the holder of this Promissory Note
may from time to time designate, the principal sum of Two Million Dollars
($2,000,000.00), or so much as may have been advanced to the BORROWER as
proceeds of the "LOAN," as such term is defined and described in the Loan And
Security Agreement ("AGREEMENT") of even date herewith between the LENDER and
the BORROWER, together with interest thereon at the rate or rates hereafter
specified until paid in full and any and all other sums which may be owing to
the holder of this Promissory Note by the BORROWER pursuant to this Promissory
Note. The following terms shall apply to this Promissory Note.

     1. Interest Rate. Interest shall accrue on the unpaid principal balance
of this Promissory Note until paid in full at the higher of: (a) seven and
one-half percent (7.5%); or (b) the annual fluctuating rate of interest which
shall equal the rate obtained by adding two percent (2.0%) to the "PRIME RATE OF
INTEREST" of the LENDER in effect from time to time. The term "PRIME RATE OF
INTEREST" means the highest prime rate of interest on corporate loans at large
U.S. Money Center Banks as presently published by The Wall Street Journal
(Eastern Edition) under the heading or column entitled "Money Rates" or in a
future substitute heading, column, or subheading published by The Wall Street
Journal, or succeeding nationally recognized publication selected by the LENDER.
Changes in the applicable interest rate shall be made as of, and immediately
upon, the occurrence of changes in the PRIME RATE OF INTEREST.

     2. Calculation Of Interest. Interest shall be calculated on the basis of a
three hundred sixty (360) days per year factor applied to the actual days on
which there exists an unpaid balance hereunder.

     3. Repayment. Accrued and unpaid interest, plus any then due applicable
late payment charges or default interest, shall be paid in consecutive monthly
payments beginning on the fifteenth calendar day of the first month immediately
following the date of this Promissory Note and continuing on the fifteenth
calendar day of each succeeding month. ALL SUMS OUTSTANDING HEREUNDER, INCLUDING
PRINCIPAL, INTEREST, CHARGES AND FEES, ARE PAYABLE IN FULL ON THAT DAY OCCURRING
SIXTY (60) CALENDAR DAYS AFTER THE DEMAND OF THE HOLDER OF THIS PROMISSORY NOTE;
PROVIDED, HOWEVER, THAT IF THERE IS AN "EVENT OF DEFAULT" (AS SUCH TERM IS
DEFINED IN THE AGREEMENT) ALL SUMS OUTSTANDING HEREUNDER ARE PAYABLE IN FULL
IMMEDIATELY UPON THE DEMAND OF THE LENDER. DEMAND FOR PAYMENT IN FULL OF ALL
SUMS DUE HEREUNDER MAY BE MADE AT ANY TIME BY THE HOLDER OF THIS PROMISSORY
NOTE, WITHOUT PRIOR NOTICE AND WITHOUT REGARD AS TO WHETHER OR NOT A DEFAULT OR
VIOLATION OF ANY OF THE BORROWER'S OBLIGATIONS UNDER THIS PROMISSORY NOTE IS
THEN EXISTING OR CONTINUING.

     4. Late Payment Charge. If any payment due hereunder, other than any
principal payment due on acceleration or demand, is not received by the holder
within fifteen (15) calendar days after its due date, the BORROWER shall pay a
late payment charge equal to five percent (5%)

<PAGE>

of the amount (excluding any principal due as a result of acceleration or
demand) then due and payable. The late payment charge shall be due whether or
not the holder declares this Promissory Note in default or accelerates and
demands immediate payment of the sums due hereunder. The existence of the right
by the holder to receive a late payment charge shall not constitute a grace
period or provide any right in the BORROWER to make a payment other than on its
due date.

     5. Application Of Payments. All payments made hereunder shall be applied
first to late payment charges or other sums owed to the holder, next to accrued
interest, and then to principal, or in such other order or proportion as the
holder, in the holder's sole discretion, may elect from time to time.

     6. Prepayment. The BORROWER may prepay this Promissory Note in whole or in
part at any time without premium or additional interest. All prepayments made
upon the unpaid principal balance of this Promissory Note shall be applied to
the unpaid principal balance in the inverse order of scheduled maturities.

     7. Rights Upon Occurrence Of An Event Of Default. Upon the occurrence of an
"EVENT OF DEFAULT," as such term is defined in the AGREEMENT, the holder of this
Promissory Note shall have the following rights in addition to such other rights
and remedies as are authorized by the AGREEMENT or otherwise available to the
holder under applicable laws:

          7.1. Acceleration. The holder of this Promissory Note, in the holder's
sole discretion and without notice or demand, may accelerate and declare due and
immediately owing the entire unpaid principal balance plus accrued interest and
all other sums payable to the holder in accordance with the terms of any of
the "LOAN DOCUMENTS," as such term is defined in the AGREEMENT.

          7.2. Default Interest Rate. The holder of this Promissory Note, in the
holder's sole discretion and without notice or demand, may raise the rate of
interest accruing on the unpaid principal balance by two (2) percentage points
above the rate of interest otherwise applicable, independent of whether the
holder elects to accelerate the unpaid principal balance as a result of such
default, unless prior to the imposition of the default rate of interest, the
BORROWER cures such event to the satisfaction of the holder hereof. Any
individual waiver of the holder's right to impose the default rate of interest
shall not be considered a waiver of this section or any future right of the
holder to impose the default rate of interest pursuant to this Section.

          7.3. Confession Of Judgment. The BORROWER authorizes any attorney
admitted to practice before any court of record in the United States to appear
on its behalf in any court in one or more proceedings, or before any clerk
thereof or prothonotary or other court official, and to confess judgment against
the BORROWER in favor of the holder of this Promissory Note in the full amount
due on this Promissory Note (including principal, accrued interest and any and
all charges, fees and costs) plus attorneys' fees equal to fifteen percent (15%)
of the amount due, plus court costs, all without prior notice or opportunity of
the BORROWER for prior hearing. The BORROWER agrees and consents that venue and
jurisdiction shall be proper in the Circuit Court of any County of the State of
Maryland or of Baltimore City, Maryland, or in the United States District Court
for the District of Maryland. The BORROWER waives the benefit of any and every
statute, ordinance, or rule of court which may be lawfully waived conferring
upon it any right or privilege of exemption, homestead rights, stay of
execution, or supplementary proceedings, or other relief from the enforcement or
immediate enforcement of a judgment or related proceedings on a judgment. The
authority and power to appear for and enter judgment against the BORROWER shall
not be

                                        2

<PAGE>

exhausted by one or more exercises thereof, or by any imperfect exercise
thereof, and shall not be extinguished by any judgment entered pursuant thereto;
such authority and power may be exercised on one or more occasions from time to
time, in the same or different jurisdictions, as often as the holder shall deem
necessary, convenient, or proper. In the event that the holder receives, as a
result of execution on a judgment confessed hereunder, attorneys' fees which
exceed the actual legal fees incurred by the holder in connection with the
unpaid balance due to the holder pursuant to this Promissory Note, then, upon
full and final payment of all other sums due and owing to the holder pursuant to
this Promissory Note and payment of the actual attorneys' fees incurred by the
holder, the holder shall remit such excess amount of attorneys' fees to the
BORROWER.

     8. Expenses Of Collection And Attorneys' Fees. Should this Promissory Note
be referred to an attorney for collection, whether or not judgment has been
confessed or suit has been filed, the BORROWER shall pay all of the holder's
reasonable costs, fees and expenses, including reasonable attorneys' fees,
resulting from such referral.

     9. Waiver Of Defenses. In the event any one or more holders of this
Promissory Note transfer this Promissory Note for value, the BORROWER agrees
that all subsequent holders of this Promissory Note who take for value and
without actual knowledge of a claim or defense of the BORROWER against a prior
holder shall not be subject to any claims or defenses which the BORROWER may
have against a prior holder, all of which are waived as to the subsequent
holder, and that all such subsequent holders shall have all rights of a holder
in due course with respect to the BORROWER even though the subsequent holder may
not qualify, under applicable law, absent this section, as a holder in due
course. The BORROWER shall retain all rights and claims which the BORROWER may
have against prior holders despite any such transfers and the waiver of defenses
provided in this section as to subsequent holders.

     10. Waiver Of Protest. The BORROWER, and all other parties to this
Promissory Note, whether maker, indorser, or guarantor, waive presentment,
notice of dishonor and protest.

     11. Extensions Of Maturity. All parties to this Promissory Note, whether
maker, indorser, or guarantor, agree that the maturity of this Promissory Note,
or any payment due hereunder, may be extended at any time or from time to time
without releasing, discharging, or affecting the liability of such party.

     12. Manner And Method Of Payment. All payments called for in this
Promissory Note shall be made in lawful money of the United States of America.
If made by check, draft, or other payment instrument, such check, draft, or
other payment instrument shall represent immediately available funds. In the
holder's discretion, any payment made by a check, draft, or other payment
instrument shall not be considered to have been made until such time as the
funds represented thereby have been collected by the holder. Should any payment
date fall on a non-banking day, the BORROWER shall make the payment on the next
succeeding banking day.

     13. Maximum Rate Of Interest. Any provision contained in any of the LOAN
DOCUMENTS to the contrary notwithstanding, the holder of this Promissory Note
shall not be entitled to receive or collect, nor shall the BORROWER be obligated
to pay, interest hereunder in excess of the maximum rate of interest permitted
by the laws of any state determined to be applicable thereto or the laws of the
United States of America applicable to loans in such applicable state or states,
and if any provisions of this Promissory Note or of any of the other LOAN
DOCUMENTS shall ever be construed or held to permit or require the charging,
collection or payment of any amount of interest in excess of that permitted by
such laws applicable thereto, the provisions of this paragraph shall

                                        3

<PAGE>

control and shall override any contrary or inconsistent provision. The intention
of the parties is to at all times conform strictly with all applicable usury
laws, and other applicable laws regulating the rates of interest which may be
lawfully charged upon the credit facility evidenced by this Promissory Note. The
interest to be paid in accordance with the terms of this Promissory Note shall
be held subject to reduction to the amount allowed under any usury or other laws
as now or hereafter construed by the courts having jurisdiction, and any sums of
money paid in excess of the interest rate allowed by law shall be applied in
reduction of the principal amounts owing under this Promissory Note.

     14. Notices. Any notice or demand required or permitted by or in connection
with this Promissory Note shall be given in the manner specified in the
AGREEMENT for the giving of notices under the AGREEMENT. Notwithstanding
anything to the contrary, all notices and demands for payment from the holder
actually received in writing by the BORROWER shall be considered to be effective
upon the receipt thereof by the BORROWER regardless of the procedure or method
utilized to accomplish delivery thereof to the BORROWER.

     15. Assignability. This Promissory Note may be assigned by the LENDER or
any holder at any time or from time to time without notice to or consent from
the BORROWER.

     16. Binding Nature. This Promissory Note shall inure to the benefit of and
be enforceable by the LENDER and the LENDER'S successors and assigns and any
other person to whom the LENDER or any holder may grant an interest in the
BORROWER'S obligations hereunder, and shall be binding and enforceable against
the BORROWER and the BORROWER'S successors and assigns.

     17. Invalidity Of Any Part. If any provision or part of any provision of
this Promissory Note shall for any reason be held invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provisions of this Promissory Note and this
Promissory Note shall be construed as if such invalid, illegal or unenforceable
provision or part thereof had never been contained herein, but only to the
extent of its invalidity, illegality, or unenforceability.

     18. Choice Of Law. The laws of the State of Maryland (excluding, however,
conflict of law principles) shall govern and be applied to determine all issues
relating to this Promissory Note and the rights and obligations of the parties
hereto, including the validity, construction, interpretation, and enforceability
of this Promissory Note and its various provisions and the consequences and
legal effect of all transactions and events which resulted in the issuance of
this Promissory Note or which occurred or were to occur as a direct or indirect
result of this Promissory Note having been executed.

     19. Consent To Jurisdiction; Agreement As To Venue. The BORROWER
irrevocably consents to the non-exclusive jurisdiction of the courts of the
State of Maryland and of the United States District Court for the District of
Maryland, if a basis for federal jurisdiction exists. The BORROWER agrees that
venue shall be proper in any circuit court of the State of Maryland selected by
the LENDER or in the United States District Court for the District of Maryland
if a basis for federal jurisdiction exists and waives any right to object to the
maintenance of a suit in any of the state or federal courts of the State of
Maryland on the basis of improper venue or of inconvenience of forum.

     20. Unconditional Obligations. The BORROWER'S obligations under this
Promissory Note shall be the unconditional duty and obligation of the BORROWER
and shall be independent

                                        4

<PAGE>

of any rights of set-off, recoupment or counterclaim which the BORROWER might
otherwise have against the holder of this Promissory Note. The BORROWER shall
pay absolutely the payments of principal, interest, fees and expenses required
hereunder, free of any deductions and without abatement, diminution or set-off.

     21. Seal And Effective Date. This Promissory Note is an instrument executed
under seal and is to be considered effective and enforceable as of the date set
forth on the first page hereof, independent of the date of actual execution and
delivery.

     22. Tense; Gender; Defined Terms; Section Headings. As used herein, the
singular includes the plural and the plural includes the singular. A reference
to any gender also applies to any other gender. Defined terms are entirely
capitalized throughout. The section headings are for convenience only and are
not part of this Promissory Note.

     23. Actions Against Lender. Any action brought by the BORROWER against the
LENDER which is based, directly or indirectly, on this Promissory Note or any
matter in or related to this Promissory Note, including but not limited to the
making of the loan evidenced hereby or the administration or collection thereof,
shall be brought only in the courts of the State of Maryland. The BORROWER may
not file a counterclaim against the LENDER in a suit brought by the LENDER
against the BORROWER in a state other than the State of Maryland unless under
the rules of procedure of the court in which the LENDER brought the action the
counterclaim is mandatory, and not merely permissive, and will be considered
waived unless filed as a counterclaim in the action instituted by the LENDER.
The BORROWER agrees that any forum other than the State of Maryland is an
inconvenient forum and that a suit brought by the BORROWER against the LENDER in
a court of any state other than the State of Maryland should be forthwith
dismissed or transferred to a court located in the State of Maryland by that
Court.

     24. Waiver Of Jury Trial. The BORROWER (by execution of this Promissory
Note) and the LENDER (by acceptance of this Promissory Note) agree that any
suit, action, or proceeding, whether claim or counterclaim, brought or
instituted by or against the BORROWER or the LENDER, or any successor or assign
of the BORROWER or the LENDER, on or with respect to this Promissory Note or any
of the other LOAN DOCUMENTS, or which in any way relates, directly or
indirectly, to the obligations of the BORROWER to the LENDER under this
Promissory Note or any of the other LOAN DOCUMENTS, or the dealings of the
parties with respect thereto, shall be tried only by a court and not by a jury.
THE BORROWER AND THE LENDER HEREBY EXPRESSLY WAIVE ANY RIGHT TO A TRIAL BY JURY
IN ANY SUCH SUIT, ACTION, OR PROCEEDING.

mutually agreed to between the LENDER and the BORROWER, such sums as the
BORROWER may request, provided that the aggregate outstanding principal balance
of the LOAN shall never exceed at any time the MAXIMUM LOAN AMOUNT. The BORROWER
shall not request or permit any advance of proceeds of the LOAN which would
cause the aggregate amount of advances made to or for the BORROWER and
outstanding under the LOAN DOCUMENTS to exceed the MAXIMUM LOAN AMOUNT. In the
event that the principal balance outstanding under the LOAN ever exceeds the
MAXIMUM LOAN AMOUNT, the BORROWER shall immediately, upon the demand of the
LENDER, reduce the principal balance of the LOAN to an amount which is not in
excess of the MAXIMUM LOAN AMOUNT. Any termination of the LOAN by the LENDER
shall relieve the LENDER of the LENDER'S obligation to lend money or to make
financial accommodations to or for the BORROWER and the BORROWER'S accounts, and

incorporated herein by reference. The date and amounts of each advance made by

amounts shall not relieve the BORROWER of its duties and obligations under the
LOAN DOCUMENTS. Interest accrued upon the LOAN shall be computed on outstanding

be considered a fee being paid by the BORROWER to the LENDER as an inducement to
the LENDER to make advances, nor shall it be considered to modify or limit the
ability of the LENDER to terminate in accordance with the provisions of this
AGREEMENT the ability of the BORROWER to borrow under the LOAN, but is instead
intended as part of the compensation which is earned by the LENDER for agreeing
to provide the LOAN in accordance with the terms of the LOAN DOCUMENTS.

          Section 2.1.4. Commitment Fee. The BORROWER shall pay to the LENDER on
or before CLOSING a non-refundable and unconditional commitment fee of Twenty

the BORROWER, even if that amount is less than the stated principal amount of
the LOAN.

BORROWER solely for funding the general working capital needs of the BORROWER.

party obligated on any of the RECEIVABLES, any rebate, refund, or adjustment to

the BORROWER, and shall be independent of any defense or any rights of set-off,
recoupment or counterclaim which the BORROWER might otherwise have against the
LENDER. The BORROWER shall pay the payments of the principal and interest to be
made upon the OBLIGATIONS, free of any deductions and without abatement,
diminution or set-off other than those herein expressly provided. Until such
time as the OBLIGATIONS have been fully paid and performed, the BORROWER shall
not: (a) suspend or discontinue any payments required by the LOAN DOCUMENTS; and
(b) fail to perform and observe all of the BORROWER'S covenants and agreements
set forth in the LOAN DOCUMENTS.

     Section 9.2. Indemnity. The BORROWER agrees to defend, indemnify and hold
harmless the LENDER and the entities affiliated with the LENDER and all of the
LENDER'S and its affiliated entities' employees, agents, officers and directors,
from and against any losses, penalties, fines, liabilities, settlements,
damages, costs and expenses, suffered in connection with any claim,

                                      -28-

investigation, litigation or other proceeding (whether or not the LENDER or an
affiliated entity is a party thereto) and the prosecution and defense thereof,
arising out of or in any way connected with any LOAN DOCUMENT, including without
limitation reasonable attorneys' and consultant's fees, except to the extent
that any of the foregoing directly result from the gross negligence or willful
misconduct of the party seeking indemnification therefor. Notwithstanding any
termination of this AGREEMENT or payment and performance of the OBLIGATIONS, the
indemnities provided for herein shall continue in full force and effect and
shall protect all of the above-described PERSONS against events arising after
such termination, payment or performance as well as before.

     Section 9.3. Lender Expenses. All LENDER EXPENSES shall be paid by the
BORROWER, whether incurred prior to or after CLOSING, such that the subject
transactions shall at all times be cost free to the LENDER.

     Section 9.4. Authorization To Obtain Financial Information. The BORROWER
hereby irrevocably authorizes its accounting firm to provide the LENDER from
time to time with such information as may be requested by the LENDER, and hereby
authorizes the LENDER to contact directly such accounting firm in order to
obtain such information.

     Section 9.5. Incorporation; Construction Of Inconsistent Provisions. The
terms and conditions of the LOAN DOCUMENTS are incorporated by reference and
made a part hereof, as if fully set forth herein. In the event of any
inconsistency between this AGREEMENT and any other LOAN DOCUMENT, such
inconsistency shall be construed, interpreted, and resolved so as to benefit the
LENDER, independent of whether this AGREEMENT or another LOAN DOCUMENT controls,
and the LENDER'S election of which interpretation or construction is for the
LENDER'S benefit shall govern.

     Section 9.6. Waivers. The LENDER at any time or from time to time may waive
all or any rights under this AGREEMENT or any other LOAN DOCUMENT, but any
waiver or indulgence by the LENDER at any time or from time to time shall not
constitute a future waiver of performance or exact performance by the BORROWER.

     Section 9.7. Continuing Obligation Of Borrower. The terms, conditions, and
covenants set forth herein and in the LOAN DOCUMENTS shall survive CLOSING and
shall constitute a continuing obligation of the BORROWER during the course of
the transactions contemplated herein. The security interests, liens and other
security provided by this AGREEMENT shall remain in effect so long as any
OBLIGATION, whether direct or contingent, is outstanding, unpaid or unsatisfied.
Upon the full and absolute payment (which payment is not subject to any possible
challenge or contest) of all of the OBLIGATIONS, the termination of any
agreement or relationship which may give rise to any future OBLIGATIONS, the
termination of any commitment or agreement of the LENDER to provide additional
credit to the BORROWER and the written request of the BORROWER, the LENDER shall
execute any document reasonably requested by BORROWER to authorize the BORROWER
to file terminations of all UCC-1 financing statements recorded evidencing the
liens granted herein, and terminate all of the LOAN DOCUMENTS, at which time the
BORROWER shall have no further duties or obligations to the LENDER thereunder.

     Section 9.8. Choice Of Law. The laws of the State of Maryland (excluding,
however, conflict of law principles) shall govern and be applied to determine
all issues relating to this AGREEMENT and the rights and obligations of the
parties hereto, including the validity, construction, interpretation, and
enforceability of this AGREEMENT and its various provisions and the consequences
and legal effect of all transactions and events which resulted in the execution
of this

                                      -29-

AGREEMENT or which occurred or were to occur as a direct or indirect result of
this AGREEMENT having been executed.

     Section 9.9. Submission To Jurisdiction; Venue; Actions Against Lender. For
purposes of any action, in law or in equity, which is based directly or
indirectly on this AGREEMENT, any other LOAN DOCUMENT or any matter related to
this AGREEMENT or any other LOAN DOCUMENT, including any action for recognition
or enforcement of any of the LENDER'S rights under the LOAN DOCUMENTS or any
judgment obtained by the LENDER in respect thereof, the BORROWER hereby:

          Section 9.9.1. Jurisdiction. Irrevocably submits to the non-exclusive
general jurisdiction of the courts of the State of Maryland and, if a basis for
federal jurisdiction exists at any time, the courts of the United States of
America for the District of Maryland.

          Section 9.9.2. Venue. Agrees that venue shall be proper in the Circuit
Court for Baltimore City, Maryland, the Circuit Court for any county in the
state of Maryland, as selected by the LENDER, and, if a basis for federal
jurisdiction exists, the courts of the United States of America for the District
of Maryland.

          Section 9.9.3. Waiver Of Objections To Venue. Waives any right to
object to the maintenance of any suit in any of the courts specified in Section
9.9.2 above on the basis of improper venue or convenience of forum. The BORROWER
further agrees that it shall not institute any suit or other action against the
LENDER, in law or in equity, which is based directly or indirectly on this
AGREEMENT, any other LOAN DOCUMENT or any matter related to this AGREEMENT or
any other LOAN DOCUMENT, in any court other than a court specified in Section
9.9.2 above; provided, that in any instance in which there is then pending a
suit instituted by the LENDER against the BORROWER in a court other than a court
specified in Section 9.9.2 above, the BORROWER may file in such suit any
counterclaim which it has against the LENDER but only if such counterclaim is a
compulsory counterclaim and would be barred if not filed as a counterclaim in
such suit. The BORROWER agrees that any suit brought by it against the LENDER
not in accordance with this paragraph should be forthwith dismissed or
transferred to a court specified in Section 9.9.2 above.

     Section 9.10. Notices. Any notice required or permitted by or in connection
with this AGREEMENT shall be in writing and shall be made by facsimile
(confirmed on the date the facsimile is sent by one of the other methods of
giving notice provided for in this Section) or by electronic mail, by hand
delivery, by Federal Express, or other similar overnight delivery service, or by
certified mail, unrestricted delivery, return receipt requested, postage
prepaid, addressed to the LENDER or the BORROWER at the appropriate address set
forth below or to such other address as may be hereafter specified by written
notice by the LENDER or the BORROWER. Notice shall be considered given as of the
date of the facsimile or the hand delivery, as of the date of receipt of
confirmation that the electronic mail was received and opened, one (1) calendar
day after delivery to Federal Express or similar overnight delivery service, or
three (3) calendar days after the date of mailing, independent of the date of
actual delivery or whether delivery is ever in fact made, as the case may be,
provided the giver of notice can establish the fact that notice was given as
provided herein. If notice is tendered pursuant to the provisions of this
Section and is refused by the intended recipient thereof, the notice,
nevertheless, shall be considered to have been given and shall be effective as
of the date herein provided.
