         2. EXERCISE OF WARRANT/REGISTRATION RIGHTS.

         (a) This ADMT Warrant may be exercised in whole or in part at any time
or from time to time during the Exercise Period; provided, however, that the
Warrant may only be exercised during such time as the shares of Common Stock
underlying the Warrant are registered for resale with the SEC. The Warrant shall
be exercised by presentation and surrender of this ADMT Warrant and a
proportionate number of the Corresponding AAN Warrants to the Company at its
principal office, or at the office of its stock transfer agent, if any, with the
Purchase Form annexed to this ADMT Warrant duly executed and accompanied by
payment of the Exercise Price for the number of shares of Common Stock specified
in the Purchase Form in cash (the Holder will receive no consideration for the
surrender of all or any portion of the Corresponding AAN Warrants) or on a
cashless basis in accordance with (i) below. If this ADMT Warrant should be
exercised in part only, the Company shall, upon surrender of this ADMT Warrant
(and a proportionate number of the Corresponding AAN Warrants) for cancellation,
execute and deliver a new ADMT Warrant (and a proportionate number of
Corresponding AAN Warrants) evidencing the rights of the Holder hereof to
purchase the balance of the shares of Common Stock purchasable hereunder. Upon
receipt by the Company of this ADMT Warrant at its office, or by the stock
transfer agent of the Company at its office, in proper form for exercise, the
Holder shall be deemed to be the holder of record of the shares of Common Stock
issuable upon such exercise, notwithstanding that the stock transfer books of
the Company shall then be closed or that certificates representing such shares
of Common Stock shall not then be actually delivered to the Holder. As soon as
practicable after each exercise of this Warrant, in whole or in part, and in any
event within seven (7) days thereafter, the Company at its expense (including
the payment by it of any applicable issue taxes) will cause to be issued in the
name of and delivered to the Holder hereof or, subject to Section 6 hereof, as
the Holder (upon payment by the Holder of any applicable transfer taxes) may
direct a certificate or certificates (with appropriate restrictive legends, as
applicable) for the number of duly authorized, validly issued, fully paid and
nonassessable shares of Common Stock to which the Holder shall be entitled upon
exercise plus, in lieu of any fractional share to which the Holder would
otherwise be entitled, all issuances of Common Stock shall be rounded up to the
nearest whole share.

            (i) The Holder may, at its option, elect to exercise this Warrant,
            in whole or in part and at any time or from time to time, on a
            cashless basis, by surrendering this Warrant, with the Purchase Form
            attached hereto duly executed by or on behalf of the Holder, at the
            principal office of the Company, or at such other office or agency
            as the Company may designate, by canceling a portion of this Warrant
            in payment of the Exercise Price payable in respect of the number of
            shares of Warrant Stock purchased upon such exercise. In the event
            of an exercise pursuant to this subsection 2(a)(i), the number of
            shares of Warrant Stock issued to the Holder shall be determined
            according to the following formula:

                           X = Y(A-B)
                               ------
                                 A
         Where:  X =       the number of shares of Warrant Stock that shall be
                           issued to the Holder;

                                       3
<PAGE>


                 Y =       the number of shares of Warrant Stock for which
                           this Warrant is being exercised (which shall include
                           both the number of shares of Warrant Stock issued to
                           the Holder and the number of shares of Warrant Stock
                           subject to the portion of the Warrant being cancelled
                           in payment of the Exercise Price);
                 A =       the Fair Market Value (as defined below) of one share
                           of Common Stock; and
                 B =       the Exercise Price then in effect.


                The Fair Market Value per share of Common Stock shall be
determined as follows:

                (1) If the Common Stock is listed on a national securities
exchange, the Nasdaq National Market, the OTC Bulletin Board or another
nationally recognized trading system as of the Exercise Date, as defined below,
the Fair Market Value per share of Common Stock shall be deemed to be the
average of the high and low reported sale prices per share of Common Stock
thereon on the trading day immediately preceding the Exercise Date, as defined
below, (provided that if the Common Stock is not so listed on such day, the Fair
Market Value per share of Common Stock shall be determined pursuant to clause
(2) below).

                (2) If the Common Stock is not listed on a national securities
exchange, the Nasdaq National Market, the OTC Bulletin Board or another
nationally recognized trading system as of the Exercise Date, as defined below,
the Fair Market Value per share of Common Stock shall be deemed to be the amount
most recently determined by the Board of Directors of the Company or an
authorized committee of the Board of Directors of the Company (the "BOARD") to
represent the fair market value per share of the Common Stock (including without
limitation a determination for purposes of granting Common Stock options or
issuing Common Stock under any plan, agreement or arrangement with employees of
the Company); and, upon request of the Holder, the Board (or a representative
thereof) shall, as promptly as reasonably practicable but in any event not later
than 15 days after such request, notify the Holder of the Fair Market Value per
share of Common Stock. Notwithstanding the foregoing, if the Board has not made
such a determination within the three-month period prior to the Exercise Date,
as defined below, then (A) the Board shall make, and shall provide or cause to
be provided to the Holder notice of, a determination of the Fair Market Value
per share of the Common Stock within 15 days of a request by the Holder that it
do so, and (B) the exercise of this Warrant pursuant to this subsection 2(a)
shall be delayed until such determination is made and notice thereof is provided
to the Holder.

         (b) Upon the listing of: (i) the AAN Common Stock on an Approved
Market, and (ii) the registration of the resale of the AAN Common Stock
underlying the AAN Warrants with the SEC, all ADMT Warrants shall immediately
expire without any value to the holder of ADMT Warrants.



                                       4
<PAGE>

         (c) The Holder hereof is hereby granted a demand registration right to
the effect that in the event that if, by March 1, 2005: (i) the Spin Off (as
described in the PPM of the Company dated May 20, 2004 and the Supplements) is
not effected, or (ii) the registration statement of the AAN Common Stock, as
described in the PPM and Supplements, has not been declared effective by the
SEC, then upon demand of Holder, the Company shall register with the SEC all of
the shares of ADMT Common Stock issuable upon the exercise of the ADMT Warrants.
The Company shall use its best efforts to have such securities registered within
30 days of the demand made by Holder. In the event that the registration
statement covering all of such securities is not declared effective by the SEC
within 90 days of the demand for registration or the registration does not
remain effective for 60 consecutive days, then the number of shares of ADMT
Common Stock issuable upon the exercise of the ADMT Warrants shall be increased
by one percent (1%) for each 30 day period (or partial period, as the case may
be) following such 90 day period. The Company covenants to maintain the
effectiveness of such registration statement until the third (3rd) anniversary
of the date of such effectiveness.

         3. RESERVATION OF SHARES; FRACTIONAL SHARES. The Company hereby agrees
that at all times there shall be reserved for issuance and/or delivery upon
exercise of this Warrant such number of shares of Common Stock as shall be
required for issuance and delivery upon exercise of this Warrant. No fractional
shares or script representing fractional shares shall be issued upon the
exercise of this Warrant. Instead, the Company will round up to the nearest
whole share.

         4. EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT. This ADMT Warrant
is exchangeable, without expense, at the option of the Holder, upon presentation
and surrender hereof (along with the Corresponding AAN Warrant) to the Company
or at the office of its stock transfer agent, if any, for other ADMT Warrants
(and Corresponding AAN Warrants) of different denominations entitling the holder
thereof to purchase in the aggregate the same number of shares of Common Stock
purchasable hereunder. Upon surrender of this ADMT Warrant (and Corresponding
AAN Warrant) to the Company or at the office of its stock transfer agent, if
any, with the Assignment Form annexed hereto duly executed and funds sufficient
to pay any transfer tax, the Company shall, without charge, execute and deliver
a new ADMT Warrant (and Corresponding AAN Warrant) in the name of the assignee
named in such instrument of assignment and this ADMT Warrant (and Corresponding
AAN Warrant) shall promptly be canceled. This ADMT Warrant (and Corresponding
AAN Warrant) may be divided or combined with other ADMT Warrants (and
Corresponding AAN Warrants) which carry the same rights upon presentation hereof
at the office of the Company or at the office of its stock transfer agent, if
any, together with a written notice specifying the names and denominations in
which new ADMT Warrants (and Corresponding AAN Warrants) are to be issued and
signed by the Holder hereof. The term "Warrant" and "ADMT Warrant" as used
herein includes any ADMT Warrants into which this Warrant may be divided or
exchanged. Upon receipt by the Company of evidence satisfactory to it of the
loss, theft, destruction or mutilation of this Warrant, and (in the case of
loss, theft or destruction) of reasonably satisfactory indemnification, and upon
surrender and cancellation of this Warrant, if mutilated, the Company will
execute and deliver a new Warrant of like tenor. Any such new Warrant executed
and delivered shall constitute an additional contractual obligation on the part
of the Company, whether or not this Warrant so lost, stolen, destroyed, or
mutilated shall be at any time enforceable by anyone.



                                       5
<PAGE>

         5. RIGHTS AND OBLIGATIONS OF THE HOLDER. The Holder shall not, by
virtue of this Warrant, be entitled to any rights of a stockholder in the
Company, either at law or equity, and the rights of the Holder are limited to
those expressed in the Warrant and are not enforceable against the Company
except to the extent set forth herein. In addition, no provision hereof, in the
absence of affirmative action by Holder to purchase shares of Common Stock, and
no enumeration herein of the rights or privileges of Holder hereof, shall give
rise to any liability of such Holder for the purchase price of any Common Stock
or as a stockholder of Company, whether such liability is asserted by Company or
by creditors of Company.

         6. ANTI-DILUTION PROVISIONS. The Exercise Price in effect at any time
and the number and kind of securities purchasable upon exercise of each Warrant
shall be subject to adjustment as follows and the Company shall give each Holder
notice of any event described below which requires an adjustment pursuant to
this Section 6 at the time of such event:

            (a) Stock Dividends, Subdivisions and Combinations. If at any time
Company shall:

                (i) take a record of the holders of its Common Stock for the
purpose of entitling them to receive a dividend payable in, or other
distribution of, shares of Common Stock,

                (ii) subdivide or reclassify its outstanding shares of Common
Stock into a larger number of shares of Common Stock, or

                (iii) combine or reclassify its outstanding shares of Common
Stock into a smaller number of shares of Common Stock or otherwise effect a
reverse stock split,

then (i) the number of shares of Common Stock for which this Warrant is
exercisable immediately after the occurrence of any such event shall be adjusted
to equal the number of shares of Common Stock which a record holder of the same
number of shares of Common Stock for which this Warrant is exercisable
immediately prior to the occurrence of such event, or the record date therefor,
whichever is earlier, would own or be entitled to receive after the happening of
such event, and (ii) the Exercise Price(s) shall be adjusted to equal (A) the
Exercise Price immediately prior to such event multiplied by the number of
shares of Common Stock for which this Warrant is exercisable immediately prior
to the adjustment divided by (B) the number of shares for which this Warrant is
exercisable immediately after such adjustment.

            (b) Certain Other Distributions and Adjustments.

                (i) If at any time Company shall take a record of the holders of
its Common Stock for the purpose of entitling them to receive any dividend or
other distribution of:

                    (A) cash,

                    (B) any evidences of its indebtedness, any shares of its
stock or any other securities or property of any nature whatsoever (other than
Convertible Securities or shares of Common Stock), or

                                       6
<PAGE>

                    (C) any warrants or other rights to subscribe for or
purchase any evidences of its indebtedness, any shares of its stock or any other
securities or property of any nature whatsoever (other than Convertible
Securities or shares of Common Stock),

then Holder, upon exercise of this Warrant, shall be entitled to receive such
dividend or distribution as if Holder had exercised this Warrant.

                (ii) A reclassification of the Common Stock (other than a change
in par value, or from par value to no par value or from no par value to par
value) into shares of Common Stock and shares of any other class of stock shall
be deemed a distribution by Company to the holders of its Common Stock of such
shares of such other class of stock and in such event Holder shall be entitled
to receive such distribution as if Holder had exercised this Warrant and, if the
outstanding shares of Common Stock shall be changed into a larger or smaller
number of shares of Common Stock as a part of such reclassification, such change
shall be deemed a subdivision or combination, as the case may be, of the
outstanding shares of Common Stock within the meaning of Section 6(a).

            (c) Issuance of Additional Shares of Common Stock.

                (i) If at any time the Company shall issue or sell any shares of
Common Stock in exchange for consideration in an amount per share of Common
Stock less than the then current Exercise Price, other than Permitted Issuances,
then (A) the Exercise Price shall be adjusted so that it shall equal the price
determined by multiplying the Exercise Price in effect immediately prior to such
event by a fraction, of which the numerator shall be the number of shares of
Common Stock outstanding on the date of issuance plus the number of additional
shares of Common Stock which the aggregate offering price would purchase based
upon the Exercise Price, and of which the denominator shall be the number of
shares of Common Stock outstanding on the date of issuance plus the number of
additional shares of Common Stock issued or issuable in such offering, and (B)
the number of shares of Common Stock for which this Warrant is exercisable shall
be adjusted to equal the product obtained by multiplying the Exercise Price in
effect immediately prior to such issue or sale by the number of shares of Common
Stock for which this Warrant is exercisable immediately prior to such issue or
sale and dividing the product thereof by the Exercise Price resulting from the
adjustment made pursuant to clause (A) above.

                (ii) The provisions of paragraph (i) of this Section 6(c) shall
not apply to any issuance of shares of Common Stock for which an adjustment is
provided under Section 6(a) or 6(b). No adjustment of the number of shares of
Common Stock for which this Warrant shall be exercisable shall be made under
paragraph (i) of this Section 6(c) upon the issuance of any shares of Common
Stock which are issued pursuant to the exercise of any warrants or other
subscription or purchase rights or pursuant to the exercise of any conversion or
exchange rights in any Convertible Securities, if any such adjustment shall
previously have been made upon the issuance of such warrants or other rights or
upon the issuance of such Convertible Securities (or upon the issuance of any
warrant or other rights therefor) pursuant to Section 6(d) or Section 6(e).



                                       7
<PAGE>

            (d) Issuance of Warrants or Other Rights. If at any time Company
shall take a record of the holders of its Common Stock for the purpose of
entitling them to receive a distribution of, or shall in any manner (whether
directly or by assumption in a merger in which Company is the surviving
corporation) issue or sell, any warrants or other rights to subscribe for or
purchase any shares of Common Stock or any Convertible Securities, whether or
not the rights to exchange or convert thereunder are immediately exercisable,
and the price per share for which Common Stock is issuable upon the exercise of
such warrants or other rights or upon conversion or exchange of such Convertible
Securities shall be less than the Exercise Price, then the number of shares for
which this Warrant is exercisable and the Exercise Price shall be adjusted as
provided in Section 6(c) on the basis that the maximum number of shares of
Common Stock issuable pursuant to all such warrants or other rights or necessary
to effect the conversion or exchange of all such Convertible Securities shall be
deemed to have been issued and outstanding and the Company shall be deemed to
have received all the consideration payable therefor, if any, as of the date of
issuance of such warrants or other rights. No further adjustment of the Exercise
Price(s) shall be made upon the actual issuance of such Common Stock or of such
Convertible Securities upon exercise of such warrants or other rights or upon
the actual issuance of such Common Stock upon such conversion or exchange of
such Convertible Securities.

            (e) Issuance of Convertible Securities. If at any time Company shall
take a record of the holders of its Common Stock for the purpose of entitling
them to receive a distribution of, or shall in any manner (whether directly or
by assumption in a merger in which Company is the surviving corporation) issue
or sell, any Convertible Securities, whether or not the rights to exchange or
convert thereunder are immediately exercisable, and the price per share for
which Common Stock is issuable upon such conversion or exchange shall be less
than the then current Exercise Price, then the number of shares of Common Stock
for which this Warrant is exercisable and the Exercise Price shall be adjusted
as provided in Section 6(c) on the basis that the maximum number of shares of
Common Stock necessary to effect the conversion or exchange of all such
Convertible Securities shall be deemed to have been issued and outstanding and
Company shall have received all of the consideration payable therefor, if any,
as of the date of issuance of such Convertible Securities. If any issue or sale
of Convertible Securities is made upon exercise of any warrant or other right to
subscribe for or to purchase any such Convertible Securities for which
adjustments of the number of shares of Common Stock for which this Warrant is
exercisable and the Exercise Price have been or are to be made pursuant to
Section 6(d), no further adjustment of the number of shares of Common Stock for
which this Warrant is exercisable and the Exercise Price shall be made by reason
of such record, issue or sale.

            (f) No adjustment in the Exercise Price shall be required unless
such adjustment would require an increase or decrease of at least one cent
($0.01) in such price; provided, however, that any adjustments which by reason
of this Section 6(f) are not required to be made shall be carried forward and
taken into account in any subsequent adjustment. All calculations under this
Section 6(f) shall be made to the nearest cent or to the nearest one-hundredth
of a share, as the case may be.

            (g) The Company may retain a firm of independent public accountants
of recognized standing selected by the Board (who may be the regular accountants
employed by the Company) to make any computation required by this Section 6.



                                       8
<PAGE>

            (h) In the event that at any time, as a result of an adjustment made
pursuant to Section 6(a), (b) or (c) of this Warrant, the Holder of any Warrant
thereafter shall become entitled to receive any shares of the Company, other
than Common Stock, thereafter the number of such other shares so receivable upon
exercise of any Warrant shall be subject to adjustment from time to time in a
manner and on terms as nearly equivalent as practicable to the provisions with
respect to the Common Stock contained in Sections 6(a) through (g), inclusive,
of this Warrant.

            (i) Notwithstanding the foregoing, no adjustment shall be effected
due to, or as a result of, any Permitted Issuances.

            (j) Other Action Affecting Common Stock. In case at any time or from
time to time Company shall take any action in respect of its Common Stock, other
than any action described in this Section 6, then, unless such action will not
have a materially adverse effect upon the rights of the Holders, the number of
shares of Common Stock or other stock for which this Warrant is exercisable
and/or the purchase price thereof shall be adjusted in such manner as may be
equitable in the circumstances.

         7. REDEMPTION. This ADMT Warrant shall not be redeemable by the Company
at anytime.

         8. OFFICER'S CERTIFICATE. Whenever the Exercise Price(s) shall be
adjusted as required by the provisions of Section 6 of this Warrant, the Company
shall forthwith file in the custody of its Secretary or an Assistant Secretary
at its principal office and with its stock transfer agent, if any, an officer's
certificate showing the adjusted Exercise Price(s) and the adjusted number of
shares of Common Stock issuable upon exercise of each Warrant, determined as
herein provided, setting forth in reasonable detail the facts requiring such
adjustment, including a statement of the number of additional shares of Common
Stock, if any, and such other facts as shall be necessary to show the reason for
and the manner of computing such adjustment. A copy of each such officer's
certificate shall be forwarded to Holder.

         9. NOTICES TO WARRANT HOLDERS. So long as this Warrant shall be
outstanding, (1) if the Company shall pay any dividend or make any distribution
upon Common Stock, or (2) if the Company shall offer to the holders of Common
Stock for subscription or purchase by them any share of any class or any other
rights, or (3) if any capital reorganization of the Company, reclassification of
the capital stock of the Company, consolidation or merger of the Company with or
into another entity, tender offer transaction for the Company's Common Stock,
sale, lease or transfer of all or substantially all of the property and assets
of the Company, or voluntary or involuntary dissolution, liquidation or winding
up of the Company shall be effected, or (4) if the Company shall file a
registration statement under the Securities Act, on any form other than on Form
S-4 or S-8 or any successor form, then in any such case, the Company shall cause

         10. RECLASSIFICATION, REORGANIZATION OR MERGER. In case of any
reclassification, capital reorganization or other change of outstanding shares
of Common Stock of the Company, or in case of any consolidation or merger of the
Company with or into another corporation (other than a merger with a subsidiary
in which merger the Company is the continuing or surviving corporation and which
does not result in any reclassification, capital reorganization or other change
of outstanding shares of Common Stock of the class issuable upon exercise of
this Warrant) or in case of any sale, lease or conveyance of all or
substantially all of the assets of the Company, the Company shall, as a
condition precedent to such transaction, cause effective provisions to be made
so that (i) the Holder shall have the right thereafter by exercising this
Warrant, to purchase the kind and amount of shares of stock and other securities
and property receivable upon such reclassification, capital reorganization and
other change, consolidation, merger, sale or conveyance by a holder of the
number of shares of Common Stock which could have been purchased upon exercise
of this Warrant immediately prior to such reclassification, change,
consolidation, merger, sale or conveyance, and (ii) the successor or acquiring
entity shall expressly assume the due and punctual observance and performance of
each covenant and condition of this Warrant to be performed and observed by
Company and all obligations and liabilities hereunder (including but not limited
to the provisions of Section 3 regarding the increase in the number of shares of
Warrant Stock potentially issuable hereunder). Any such provision shall include
provision for adjustments which shall be as nearly equivalent as possible to the
adjustments provided for in this Warrant. The foregoing provisions of this
Section 10 shall similarly apply to successive reclassifications, capital
reorganizations and changes of shares of Common Stock and to successive
consolidations, mergers, sales or conveyances. In the event that in connection
with any such capital reorganization or reclassification, consolidation, merger,
sale or conveyance, additional shares of Common Stock shall be issued in
exchange, conversion, substitution or payment, in whole in part, for a security
of the Company other than Common Stock, any such issue shall be treated as an
issuance of Common Stock covered by the provisions of Section 6 of this Warrant.

         11. TRANSFER TO COMPLY WITH THE SECURITIES ACT OF 1933. This Warrant or
the Warrant Stock or any other security issued or issuable upon exercise of this
Warrant may not be sold or otherwise disposed of except as follows:

             (i) to a person who, in the opinion of counsel for the Company, is
a person to whom this Warrant or Warrant Stock may legally be transferred
without registration and without the delivery of a current prospectus under the
Act with respect thereto and then only against receipt of an agreement of such
person to comply with the provisions of this Section 11 with respect to any
resale or other disposition of such securities which agreement shall be
satisfactory in form and substance to the Company and its counsel; or

                                       10
<PAGE>

             (ii) to any person upon delivery of a prospectus then meeting the
requirements of the Act relating to such securities and the offering thereof for
such sale or disposition.

         12. GOVERNING LAW; JURISDICTION. The corporate laws of the State of
Delaware shall govern all issues concerning the relative rights of the Company
and its stockholders. All issues concerning the construction, validity,
enforcement and interpretation of this Warrant shall be governed by and
construed in accordance with the internal laws of the State of New York without
giving effect to the principles of conflicts of law thereof. The parties hereto
agree that venue in any and all actions and proceedings related to the subject
matter of this Warrant shall be in the state and federal courts in and for New
York, New York, which courts shall have exclusive jurisdiction for such purpose,
and the parties hereto irrevocably submit to the exclusive jurisdiction of such
courts and irrevocably waive the defense of an inconvenient forum to the
maintenance of any such action or proceeding. Service of process may be made in
any manner recognized by such courts. This Warrant and any term hereof may be
changed, waived, discharged or terminated only by an instrument in writing
signed by the party against which enforcement of the change, waiver, discharge
or termination is sought.

         13. NOTICES. Any and all notices or other communications or deliveries
