      As  described under Item 5(c) above, on April 3, 2000 FW II acquired  from
the Issuer the Convertible Note and the FW II Warrant.  On November 6, 1997,  FW
Partners and the Issuer entered into a letter agreement (the "Letter Agreement")
that  amended  the  registration rights provisions  of  the  Purchase  Agreement
pursuant to which FW Partners acquired shares of the Stock and warrants from the
Issuer  in May, 1996, as described in the Schedule 13D.  The description of  the
Convertible  Note, the FW II Warrant and the Letter Agreement  that  follows  is
not,  and  does not purport to be, complete and is qualified in its entirety  by
reference  to the Convertible Note, the FW II Warrant and the Letter  Agreement,
as  applicable, the forms of which are attached hereto as Exhibits  99.4,  99.5,
and 99.6, respectively.

     Convertible Note

      The  Convertible Note provides for interest on the unpaid principal amount
thereof at a rate equal to the prime rate announced from time to time by Bank of
America,  Atlanta, Georgia, plus 4%.  Interest is payable quarterly  in  arrears
and  the  principal is payable in full on March 30, 2002 (the "Maturity  Date").
If  on  or  prior to the Maturity Date the Issuer completes a public or  private
issuance  of  the  Issuer's equity securities, FW II shall  have  the  right  to
convert the outstanding principal amount of the Convertible Note, in whole or in
part,  into  shares  of  the  equity securities of the  Issuer  issued  in  such
offering.   The  number  of  shares issuable upon any such  conversion  will  be
determined by dividing the outstanding principal amount of the Convertible  Note
submitted for conversion by the lowest price per share of the class or series of
equity  securities being issued, as described in Section 5.1 of the  Convertible
Note.

     FW II Warrant

     The FW II Warrant is exercisable at any time, in whole or in part, prior to
March  30, 2005, into 112,994 shares of the Stock at a price of $1.77 per share,
subject to adjustment as described therein.

     Letter Agreement

     The Letter Agreement amended the Purchase Agreement to provide Keystone, D.
Brown,  Wolfson  and "affiliates" or "associates" thereof,  as  such  terms  are
defined  in  the  Securities Act of 1933, as amended, with  certain  demand  and
"piggyback" registration rights through May 20, 2001.

        Except as set forth herein or in the Exhibits filed herewith, there are
no contracts, arrangements, understandings or relationships with respect to
shares of the Stock owned by the Reporting Persons.

                           CONVERTIBLE PROMISSORY NOTE

NEITHER  THIS  NOTE  NOR  ANY  STOCK ISSUED UPON  CONVERSION  HEREOF  HAVE  BEEN
REGISTERED  UNDER  THE SECURITIES ACT OF 1933, AS AMENDED  (THE  "ACT")  OR  ANY
APPLICABLE STATE SECURITIES OR BLUE SKY LAWS (THE "STATE LAWS"), AND MAY NOT  BE
SOLD  OR TRANSFERRED IN THE ABSENCE OF REGISTRATION UNDER THE ACT AND STATE LAWS
OR AN EXEMPTION FROM REGISTRATION THEREUNDER.


                           CONVERTIBLE PROMISSORY NOTE



April 3, 2000                                          $1,000,000


            AER  ENERGY  RESOURCES, INC., a Georgia corporation (the "Company"),
hereby  promises  to  pay to the order of FW AER II, L.P.,  a  Delaware  limited
partnership  (together with any subsequent holder of this Note,  the  "Holder"),
the principal amount of ONE MILLION AND NO/100 DOLLARS ($1,000,000.00), together
with  interest  thereon calculated from the date hereof in accordance  with  the
provisions  of  this  Note.   Capitalized terms used herein  and  not  otherwise
defined shall have the meanings assigned to them in Section 7.

          1.   Payment of Interest.

          1.1   Computation  and Payment of Interest.  Interest  on  the  unpaid
principal  amount of this Note outstanding from time to time shall accrue  on  a
daily basis at a rate per annum equal to the Prime Rate (as defined below)  plus
four  percent (4.0%) and shall be computed on the basis of a three hundred sixty
(360)  day year for the actual number of days elapsed in the period during which
it  accrues.  On and after the occurrence and during the continuance of an Event
of Default, at the option of the Holder, interest on the unpaid principal amount
of  this Note outstanding from time to time shall accrue on a daily basis  at  a
rate  per  annum equal to the Prime Rate plus six percent (6.0%)  (the  "Default
Rate").

          Accrued interest shall be due and payable quarterly in arrears on  the
first  day of January, April, July and October of each year, commencing July  1,
2000.   Accrued  interest  also shall be due and payable  on  the  date  of  any
voluntary  or  mandatory  prepayment  of this  Note,  at  maturity,  whether  by
acceleration  or  otherwise,  and on the date of any  conversion  of  this  Note
pursuant  to  Section  5.   Interest payable after maturity  of  this  Note  (by
acceleration or otherwise) shall be payable upon demand.

          As  used  herein,  "Prime Rate" means the rate  of  interest  publicly
announced from time to time by Bank of America, Atlanta, Georgia, as its  "Prime
Rate" or "Base Rate" for commercial loans made by such bank.  The interest  rate
hereunder  shall be adjusted on the effective date of any change  in  the  Prime
Rate  to  reflect  the Prime Rate then in effect. In the event  that  such  bank
ceases  to  publish a "Prime Rate" or "Base Rate" for its commercial loans,  the
Holder  may specify an alternate source for the Prime Rate by delivering written
notice thereof to the Company.

          1.2   Interest  Laws.  Notwithstanding any provision to  the  contrary
contained in this Note, the Company shall not be required to pay, and the Holder
shall  not  be  permitted to collect, any amount of interest in  excess  of  the
maximum amount of interest permitted by law ("Excess Interest").  If any  Excess
Interest  is provided for or determined by a court of competent jurisdiction  to
have been provided for in this Note, then in such event:  (a) the provisions  of
this  Section  1.2  shall  govern and control; (b)  the  Company  shall  not  be
obligated  to pay any Excess Interest; (c) any Excess Interest that  the  Holder
may  have received hereunder shall be, at the Holder's option, (i) applied as  a
credit  against  the outstanding principal balance of this Note or  accrued  and
unpaid  interest  (not  to  exceed the maximum amount permitted  by  law),  (ii)
refunded  to  the  Company, or (iii) any combination of the foregoing;  (d)  the
interest rate provided for herein shall be automatically reduced to the  maximum
lawful rate allowed from time to time under applicable law (the "Maximum Rate"),
and  this  Note shall be deemed to have been and shall be, reformed and modified
to reflect such reduction; and (e) the Company shall not have any action against
the  Holder  for  any damages arising out of the payment or  collection  of  any
Excess  Interest.   Notwithstanding the foregoing, if for  any  period  of  time
interest  on  this  Note  is  calculated at the Maximum  Rate  rather  than  the
applicable  rate  under this Note, and thereafter such applicable  rate  becomes
less  than  the  Maximum Rate, the rate of interest payable on this  Note  shall
remain  at  the Maximum Rate until the Holder shall have received the amount  of
interest  which the Holder would have received during such period on  this  Note
had  the  rate  of  interest not been limited to the Maximum  Rate  during  such
period.

          2.   Payment of Principal.

          2.1  Scheduled Payment.  The Company shall pay in full the outstanding
principal  amount  of this Note to the Holder on March 30, 2002  (the  "Maturity
Date").

          2.2   Voluntary  Prepayments.  The Company may  prepay  the  principal
amount  of  this  Note  in whole only upon not less than ten  (10)  days'  prior
written notice to the Holder; provided, however, that the Company may not prepay
this  Note  after the date that the Company receives a notice of  conversion  of
this  Note  pursuant  to Section 5 notwithstanding that  the  Company  may  have
previously delivered a notice of prepayment to the Holder, and upon delivery  of
any such notice of conversion, all outstanding notices of prepayment (regardless
of when delivered) shall be deemed automatically rescinded.  The Company may not
prepay the principal amount of this Note in part.

          2.3   Mandatory Prepayment.  Upon the closing of any Equity  Issuance,
the  Holder  may  require the Company to apply all or any  portion  of  the  Net
Proceeds  of  such  Equity Issuance in prepayment of the  outstanding  principal
amount  of this Note (or portion thereof); provided, however, in the event  that
the holder of the Other Note requires the Company to apply all of any portion of
such  Net  Proceeds in prepayment of the Other Note and the amount of  such  Net
Proceeds is less than the aggregate principal of this Note and the Other Note to
be  prepaid,  then such Net Proceeds shall be applied pro rata in prepayment  of
this  Note and the Other Note based on the relative amounts of principal  as  to
which  the  Holder  and  the  holder of the Other  Note  require  prepayment  in
connection with such Equity Issuance.

          3.   Manner and Time of Payment.

          3.1   Payment  in  Same Day Funds.  All payments by the  Company  with
respect  to  this  Note  shall  be made without deduction,  defense,  setoff  or
counterclaim and in same day funds and delivered to the Holder by wire  transfer
to  such  account  as the Holder may designate from time to time.   The  Company
shall  receive  credit for such funds on the date received  if  such  funds  are
received by the Holder by 2:00 p.m. (Atlanta, Georgia time) on such day.  In the
absence of timely receipt, such funds shall be deemed to have been paid  by  the
Company on the next succeeding Business Day.

          3.2   Payment on Non-Business Days.  If any payment on this Note shall
become  due on a day that is not a Business Day, such payment shall be  made  on
the  next succeeding Business Day and such extension of time shall in such  case
be included in computing any interest due in connection with such payment.

          4.   Events of Default.

          4.1   Definition.   For purposes of this Note, an "Event  of  Default"
shall be deemed to have occurred:

          (a)  if the Company fails to pay any interest then accrued and payable
     with  respect to this Note (and such failure continues for a period of five
     (5) days after notice thereof to the Company);

          (b)   if the Company fails to pay any principal on this Note when  due
     (and  such  failure  continues for a period of five (5) days  after  notice
     thereof to the Company);

          (c)   if the Company breaches or otherwise fails to perform or observe
     any  covenant  or  agreement contained in this Note  and  such  failure  to
     perform  or  observe is not cured within ten (10) days  after  the  Company
     receives notice of the occurrence thereof;

          (d)   if  the Company makes an assignment for the benefit of creditors
     or  admits  in  writing its inability to pay its debts  generally  as  they
     become  due;  or  an order, judgment or decree is entered adjudicating  the
     Company bankrupt or insolvent; or any order for relief with respect to  the
     Company  is entered under the United States Bankruptcy Code; or the Company
     petitions  or  applies to any tribunal for the appointment of a  custodian,
     trustee, receiver or liquidator of the Company, or of any substantial  part
     of  the assets of the Company, or commences any proceeding relating to  the
     Company  under  any  bankruptcy  reorganization,  arrangement,  insolvency,
     readjustment  of debt, dissolution or liquidation law of any  jurisdiction;
     or  any  such  petition or application is filed, or any such proceeding  is
     commenced,  against  the  Company and either (i) the  Company  by  any  act
     indicates  its approval thereof, consents thereto or acquiesces therein  or
     (ii) such petition, application or proceeding is not dismissed within sixty
     (60) days;

          (e)   if any money judgment, writ or warrant of attachment, or similar
     process  is entered or filed against the Company or any of its assets,  and
     remains  undischarged, unvacated, unbonded and unstayed  for  a  period  of
     thirty (30) days; or

          (f)   if  any order, judgment or decree is entered against the Company
     decreeing the dissolution or split up of the Company and such order remains
     undischarged or unstayed for a period in excess of twenty (20) days.

          4.2  Consequences of Event of Default.

          (a)   If  an Event of Default of the type described in Section  4.1(d)
has  occurred,  the entire outstanding principal amount of this Note,  plus  all
accrued  interest  thereon,  shall  automatically  become  immediately  due  and
payable, without any demand or other action on the part of the Holder.

          (b)   If  any  Event  of Default other than of the type  described  in
Section 4.1(d) has occurred, the Holder may declare (by written notice delivered
to  the Company) all or any portion of the outstanding principal amount of  this
Note,  plus  all accrued interest thereon, due and payable and demand  immediate
payment of all or any portion of the outstanding principal amount of this  Note,
plus  all accrued interest thereon.  The Holder shall also have any other rights
which  the Holder may have been afforded under any contract or agreement at  any
time and any other rights which the Holder may have pursuant to applicable law.

          5.   Conversion.

          5.1   Conversion  Option.  If on or prior to the  Maturity  Date,  the
Company  consummates an Equity Issuance, then, provided that the  Holder  is  at
that  time an "accredited investor" as defined in Regulation D promulgated under
the  Act, the Holder shall have the right, on the effective date of such  Equity
Issuance, to convert the outstanding principal amount of this Note, in whole  or
in part, to shares of the equity securities issued by the Company in such Equity
Issuance.   If more than one class or series of shares of equity securities  are
issued  in  such Equity Issuance, then the Holder may elect to receive  in  such
conversion  any one or more of such classes or series of securities.   Upon  any
such  conversion, the Company shall issue to the Holder the number of shares  of
each  class  or  series  of such equity securities that  the  Holder  elects  to
receive, as determined in accordance with the following formula:


               N =      O
                    P

     where:

     N   =     the number of shares of such class or series of equity securities
          to be issued to the Holder upon such conversion

     O   =      the  outstanding principal amount of this Note to  be  converted
          into such class or series

     P   =      the  lowest  price per share of such class or series  of  equity
          securities  issued to any Person other than the Holder  in  connection
          with such Equity Issuance

          5.2   Manner  of  Conversion.  The Holder may exercise  the  right  to
convert  this Note pursuant to Section 5.1 by delivering written notice of  such
exercise to the Company, which notice shall specify the portion of the principal
balance  of  this  Note as to which the Holder elects such  conversion  and  the
class(es)  or  series of securities to be received upon such  conversion.   Such
notice  may be delivered to the Company at any time prior to the closing of  the
Equity  Issuance. In the event that the Holder exercises such conversion option,
then  at  the closing of the Equity Issuance, the Company shall deliver  to  the
Holder  or  to such other Person as the Holder shall designate in its notice  of
conversion  one or more certificates evidencing the shares of equity  securities
into which this Note (or portion) is converted, which certificate(s) shall be in
the name of the Holder or such other Person as the Holder shall designate in its
notice  of exercise and, in the case of a partial conversion, a new note in  the
amount  of  the  unconverted principal balance hereof.   In  exchange  for  such
certificate(s)  and any such new note, the Holder shall deliver to  the  Company
the  original  of  this Note.  On the date of any such conversion,  the  Company
shall  pay to the Holder in cash, all accrued but unpaid interest on the portion
of the principal amount of this Note that is so converted.

          5.3  Notice of Equity Issuance.  Not less than ten (10) days prior  to
the  expected closing date of any Equity Issuance, the Company shall deliver  to
the  Holder written notice of such Equity Issuance, which notice shall set forth
the  material  terms  of  such Equity Issuance and  the  expected  closing  date
thereof.

          6.   Miscellaneous Provisions.

          6.1   Waiver of Demand and Notice.  The Company hereby waives  demand,
notice,  protest  and  all  other demands and notices  in  connection  with  the
delivery, acceptance, performance, default or enforcement of this Note.

          6.2   Governing  Law.  This Note shall be construed  and  enforced  in

the  State  of  Georgia, without giving effect to provisions  thereof  regarding
conflict of laws.

          6.3  Consent to Jurisdiction and Service of Process.  The Company and,
by  its acceptance hereof, the Holder hereby consent to the jurisdiction of  any
state  or  federal court located in Atlanta, Georgia and irrevocably agree  that
subject to the Holder's election, all actions or proceedings arising out  of  or
relating  to  this Note shall be litigated in such courts.  The Company  accepts
for itself and in connection with its properties, generally and unconditionally,
the nonexclusive jurisdiction of the aforesaid courts and waives any defense  of
forum  non  conveniens,  and irrevocably agrees to  be  bound  by  any  judgment
rendered thereby in connection with this Note.

          6.4   Expenses  and  Attorneys'  Fees.   The  Company  shall  promptly
reimburse  the  Holder  for all fees, costs and expenses  (including  reasonable
attorneys' fees) incurred by the Holder in any action to enforce this Note or to
collect any payments due from the Company under this Note.

Atlanta, Georgia time, on March 30, 2005.

     This  Warrant is issued and all rights hereunder shall be held  subject  to
all of the conditions, limitations and provisions set forth herein.

     1.   Exercise.

     This Warrant may be exercised as to all or any lesser number of full shares
of  Common  Stock  covered  hereby upon surrender  of  this  Warrant,  with  the
Subscription Form attached hereto duly executed, together with the full Exercise
Price  in  cash,  or  by certified or official bank check payable  in  New  York
Clearing House Funds for each share of Common Stock as to which this Warrant  is
exercised,  at  the  office  of the Company, AER Energy  Resources,  Inc.,  4600
Highlands Parkway, Suite G, Smyrna, GA 30082, or at such other office or  agency
as  the Company may designate in writing (such surrender and payment hereinafter
called  the "Exercise of this Warrant").  The "Date of Exercise" of the  Warrant
shall be defined as the date that the original Warrant and Subscription Form are
received by the Company.  This Warrant shall be canceled upon its Exercise, and,
as  soon  as  practicable thereafter, the Holder hereof  shall  be  entitled  to
receive  a certificate or certificates for the number of shares of Common  Stock
purchased  upon  such Exercise and a new Warrant or Warrants  (containing  terms
identical to this Warrant) representing any unexercised portion of this Warrant.
Each  person in whose name any certificate for shares of Common Stock is  issued
shall,  for all purposes, be deemed to have become the Holder of record of  such
shares  on  the Date of Exercise of this Warrant, irrespective of  the  date  of
delivery  of  such certificate.  Nothing in this Warrant shall be  construed  as
conferring upon the Holder hereof any rights as a shareholder of the Company.

     2.   Payment of Warrant Exercise Price.

     Payment  of  the Exercise Price may be made by any of the following,  or  a
combination thereof, at the election of Holder:

     (i)  cash, certified check or cashiers check or wire transfer; or

     (ii)  surrender  of  this Warrant at the principal office  of  the  Company
together with notice of election, in which event the Company shall issue  Holder
a number of shares of Common Stock computed using the following formula:

                    X = Y (A-B)/A

where:          X  = the number of shares of Common Stock to be issued to Holder
          (not  to  exceed the number of shares set forth on the cover  page  of
          this  Warrant, as adjusted pursuant to the provisions of Section 4  of
          this Warrant).

          Y  =  the  number of shares of Common Stock for which this Warrant  is
          being exercised.

          A  =  the  Market Price of one share of Common Stock (for purposes  of
          this Section 2(ii), the "Market Price" shall be defined as the average
          closing bid price of the Common Stock for the five trading days  prior
          to  the  Date  of Exercise of this Warrant (the "Average  Closing  Bid
          Price"),  as reported on the Nasdaq National Market, or if the  Common
          Stock is not traded on the Nasdaq National Market, the Average Closing
          Bid  Price in the over-the-counter market; provided, however, that  if
          the Common Stock is listed on a stock exchange, the Market Price shall
          be the Average Closing Bid Price on such exchange).

          B = the Exercise Price.

It is intended that the Common stock issuable upon exercise of this Warrant in a
cashless exercise transaction shall be deemed to have been acquired at the  time
this Warrant was issued, for purposes of Rule 144(d)(3)(ii).

     3.   Transfer and Registration.

     Subject to the provisions of Section 7 of this Warrant, this Warrant may be
transferred  on  the books of the Company, wholly or in part, in  person  or  by
attorney,  upon  surrender  of this Warrant properly  endorsed,  with  signature
guaranteed.  This Warrant shall be canceled upon such surrender and, as soon  as
practicable  thereafter,  the person to whom such  transfer  is  made  shall  be
entitled to receive a new Warrant or Warrants as to the portion of this  Warrant
transferred, and the Holder of this Warrant shall be entitled to receive  a  new
Warrant or Warrants as to the portion hereof retained.

     4.   Anti-Dilution Adjustments.

     (a)   If the Company shall at any time declare a dividend payable in shares
of Common Stock, then the Holder hereof, upon Exercise of this Warrant after the
record date for the determination of Holders of Common Stock entitled to receive
such  dividend, shall be entitled to receive upon Exercise of this  Warrant,  in
addition  to  the number of shares of Common Stock as to which this  Warrant  is
Exercised,  such  additional shares of Common stock as such  Holder  would  have
received had this Warrant been Exercised immediately prior to such record date.

     (b)   If  the  Company  shall  at  any time effect  a  recapitalization  or
reclassification  of  such character that the shares of Common  stock  shall  be
changed  into or become exchangeable for a larger or smaller number  of  shares,
then upon the effective date thereof, the number of shares of Common Stock which
the  Holder  hereof shall be entitled to purchase upon Exercise of this  Warrant
shall be increased or decreased, as the case may be, in direct proportion to the
increase or decrease in the number of shares of Common Stock by reason  of  such
recapitalization or reclassification, and the Exercise Price shall  be,  in  the
case  of an increase in the number of shares, proportionately decreased and,  in
the case of a decrease in the number of shares, proportionally increased.

     (c)  If the Company shall at any time distribute to Holders of Common Stock
cash,  evidences of indebtedness or other securities or assets (other than  cash
dividends or distributions payable out of earned surplus or net profits for  the
current  or  preceding year) then, in any such case, the Holder of this  Warrant
shall  be  entitled to receive, upon Exercise of this Warrant, with  respect  to
each  share of Common Stock issuable upon such Exercise, the amount of  cash  or
evidences of indebtedness or other securities or assets which such Holder  would
have been entitled to receive with respect to each such share of Common stock as
a  result  of  the  happening  of such event had  this  Warrant  been  Exercised
immediately  prior  to the record date or other date fixing shareholders  to  be
affected  by such event (the "Determination Date") or, in lieu thereof,  if  the
Board  of  Directors  of the Company should so determine at  the  time  of  such
distribution,  a reduced Exercise Price determined by multiplying  the  Exercise
Price  on  the Determination Date by a fraction, the numerator of which  is  the
result  of  such  Exercise  Price  reduced by the  value  of  such  distribution
applicable  to  one  share of Common stock (such value to be determined  by  the
Board in its discretion) and the denominator of which is such Exercise Price.

     (d)   If the Company shall at any time consolidate or merge with any  other
corporation or transfer all or substantially all of its assets or dissolve, then
the  Company  shall  deliver  written notice  to  the  Holder  of  such  merger,
consolidation or sale of assets or dissolution at least thirty (30)  days  prior
to  the  closing of such merger, consolidation or sale of assets or dissolution,
and this Warrant shall terminate and expire immediately prior to the closing  of
such merger, consolidation or sale of assets or dissolution.

     (e)   As  used  in this Warrant, the term "Exercise Price" shall  mean  the
purchase  price per share specified in this Warrant until the occurrence  of  an
event  stated  in Section 4 (b) or (c) and thereafter shall mean said  price  as
adjusted  from time to time in accordance with the provisions of said  sections.
No  such  adjustment  shall  be  made unless such adjustment  would  change  the
Exercise  Price  at  the  time  by $.01 or more;  provided,  however,  that  all
adjustments  not  so made shall be deferred and made when the aggregate  thereof
would change the Exercise Price at the time by $.01 or more.  No adjustment made
pursuant  to any provision of this Section 4 shall have the effect of increasing
the  total consideration payable upon Exercise of this Warrant in respect of all
the Common Stock as to which this Warrant may be exercised.

     (f)   In  the  event  that at any time, as a result of an  adjustment  made
pursuant  to this Section 4, the Holder of this Warrant shall, upon Exercise  of
this  Warrant,  become  entitled to receive shares and/or  other  securities  or
assets  (other  than  Common Stock) then, wherever appropriate,  all  references
herein  to  shares of Common Stock shall be deemed to refer to and include  such
shares  and/or  other securities or assets; and thereafter the  number  of  such
shares  and/or  other securities or assets shall be subject to  adjustment  from
time  to time in a manner and upon terms as nearly equivalent as practicable  to
the provisions of this Section 4.

     5.   Fractional Interests.

          No  fractional shares or scrip representing fractional shares shall be
issuable upon the Exercise of this Warrant, but on Exercise of this Warrant, the
Holder  hereof may purchase only a whole number of shares of Common Stock.   The
Company  shall make a payment in cash in respect of any fractional shares  which
might  otherwise  be  issuable  upon Exercise of  this  Warrant,  calculated  by
multiplying  the  fractional share amount by the market price  of  the  Companys
Common  Stock on the Date of Exercise as reported on the Nasdaq National  Market
or such other exchange or system on which the Companys Common Stock is traded.

     6.   Reservation of Shares.

          The  Company  shall at all times reserve for issuance such  number  of
authorized  and unissued shares of Common Stock (or other securities substituted
therefor as herein above provided) as shall be sufficient for Exercise  of  this
Warrant.   The Company covenants and agrees that upon Exercise of this  Warrant,
all shares of Common Stock issuable upon such Exercise shall be duly and validly
issued,  fully paid, nonassessable and not subject to preemptive rights  of  any
shareholders.

     7.   Restrictions on Transfer.

          This  Warrant  and the Common Stock issuable on Exercise  hereof  have
been or will be acquired by the Holder hereof for investment for its own account
and  not with a view to the distribution thereof, have not been registered under
the Securities Act of 1933, as amended (the "Act") or under any state securities
laws (the "State Acts"), and may not be sold, transferred, pledged, hypothecated
or  otherwise disposed of in the absence of registration or the availability  of
an  exemption from registration under the Act and any applicable State Acts and,
in  the  event a Holder believes an exemption from the registration requirements
of the Act and any applicable State Acts is available, the Holder must deliver a
legal opinion satisfactory in form and substance to the Company and its counsel,
stating  that  such exemption is available.  All shares of Common  Stock  issued
upon   Exercise of this Warrant shall bear an appropriate legend to such effect.
Holder  has represented to the Company that it and any transferee of all or  any
portion  of  this Warrant is and will remain at all times while this Warrant  is
outstanding  an  "accredited investor" as defined in  Regulation  D  promulgated
under the Act.

     8.   Benefits of this Warrant.

          Nothing  in this Warrant shall be construed to confer upon any  person
other  than  the Company and the Holder of this Warrant any legal  or  equitable
right, remedy or claim under this Warrant and this Warrant shall be for the sole
and exclusive benefit of the Company and the Holder of this Warrant.

     9.   Applicable Law.

          This Warrant is issued under and shall for all purposes be governed by
and construed in accordance with the laws of the State of Georgia.  Jurisdiction
for any dispute regarding this Warrant lies in Georgia.

     10.  Loss of Warrant.

          Upon   receipt  by  the  Company  of  evidence  of  the  loss,  theft,
destruction  or mutilation of this Warrant, and (in the case of loss,  theft  or
destruction)  of indemnity or security reasonably satisfactory to  the  Company,
and  upon surrender and cancellation of this Warrant, if mutilated, the  Company
shall execute and deliver a new Warrant of like tenor and date.

     11.  Notice to Company and Holder.

          Notices or demands pursuant to this Warrant to be given or made by the
Holder of this Warrant to or on the Company shall be sufficiently given or  made
if  sent  by  certified  or registered mail, return receipt  requested,  postage

FW AER Partners, L.P.
201 Main Street, Suite 3100
Fort Worth, Texas  76102

Dear Sirs:

     This  letter  amends  that  certain AER Energy Resources,  Inc.  Securities
Purchase  Agreement  by  and  between FW AER Partners,  L.P.,  a  Texas  limited
partnership ("Purchaser"), and AER Energy Resources, Inc., a Georgia corporation
("AER"),  dated  as  of May 13, 1996 (the "Agreement"), pursuant  to  which  the
Purchaser  purchased  from AER 1,584,158 shares of AER's common  stock,  no  par
value  (the "Common Stock"), and a warrant to purchase 835,000 shares of  Common
Stock.   All defined terms used but not otherwise defined herein shall have  the
respective meanings given them in the Agreement.

     1.  Section 4(a) of the Agreement is hereby amended to read in its entirety
as follows:

     (a)  Demand Registration.  If at any time after two (2) years and prior  to
five (5) years from the date of the Closing, AER shall receive a written request
from  Purchaser that AER file a registration statement under the Securities Act,
covering  all or any portion of the Shares or all or any portion of the  Warrant
Shares, AER shall, not later than ninety (90) days after receipt of such written
request,  file  a  registration statement with the Commission  relating  to  the
Shares  or  Warrant  Shares as to which such request for a  demand  registration
relates  together with all other shares of Common Stock owned by  Purchaser  and
shares  of Common Stock owned by Keystone, Inc., David G. Brown, Mark A. Wolfson
or  "affiliates"  or  "associates" thereof, as such terms  are  defined  in  the
Securities  Act (collectively, the "Third Party Shareholders"),  to  the  extent
such  shares of Common Stock are not then freely tradeable under the  Securities
Act,  as  the  notice  requests be included in such  registration  (all  of  the
foregoing hereinafter collectively referred to as, the "Requested Shares"),  and
AER  shall  use its best efforts to cause the registration statement (which  may
cover, without limitation, an offering on a delayed or continuous basis open for
up  to  one hundred eighty (180) days pursuant to Commission Rule 415)  for  the
Requested  Shares to become effective under the Securities Act.   AER  shall  be
obligated  to  effect only two (2) registrations pursuant to this Section  4(a).
Any  such  request  shall be subject to the rights of the Debenture  Subscribers
(defined  below)  pursuant  to the Registration Rights  Agreement  dated  as  of
November  22,  1995 among AER, the Debenture Subscribers and Swartz Investments,
Inc. (the "Registration Rights Agreement").

     2.  Section 4(c) of the Agreement is hereby amended to read in its entirety
as follows:

     (c)   "Piggyback"  Registration.  If at any time after two  (2)  years  and
prior  to  five (5) years from the date of the Closing, AER shall  determine  to
proceed  with the preparation and filing of a registration statement  under  the
Securities Act in connection with the proposed offer and sale for money  of  any
of  its  equity securities by it or any of its security holders (other  than  on
Form  S-4  or Form S-8 promulgated under the Securities Act or any successor  or
similar  form), AER will give written notice of its determination to  Purchaser.
Upon  the  written request of Purchaser or any Third Party Shareholder given  to
AER  within ten (10) days after Purchaser's receipt of any such notice  by  AER,
AER  will cause all of the shares of Common Stock that Purchaser and/or  any  of
the  Third  Party  Shareholders  have requested be  registered  (the  "Piggyback
Shares")  to be included in such registration statement, but only to the  extent
the  shares  of Common Stock are not then freely tradeable under the  Securities
Act; provided, however, that such request shall be subject to the rights of  the
Debenture  Subscribers  pursuant  to  the  Registration  Rights  Agreement,  and
provided,  further,  that,  if  the managing underwriter,  in  the  case  of  an
underwritten  public  offering,  determines and  advises  in  writing  that  the
inclusion  of  all the Piggyback Shares proposed to be included by Purchaser  or
the Third Party Shareholders, as applicable, would interfere with the successful
marketing of the securities proposed to be registered by AER, then the number of
such  Piggyback  Shares to be included in the registration  statement  shall  be
reduced  in  accordance  with the recommendations of the  managing  underwriter,
except  that  if  the  managing  underwriter determines  and  advises  that  the
inclusion  in  such  registration statement of any  Piggyback  Shares  would  so
interfere,  then  no  Piggyback Shares shall be included  in  such  registration
statement  but  provided that any such reduction shall be  made  pro  rata  with
respect   to   Purchaser  and  any  Third  Party  Shareholder  requesting   such
registration.

     3.  Section 4(d) of the Agreement is hereby amended to read in its entirety
as follows:

     (d)   Expenses. With respect to each inclusion of shares in a  registration
statement  pursuant to Section 4(a) or 4(b), AER shall bear the following  fees,
costs  and  expenses: all registration, filing and NASD fees, printing expenses,
fees and disbursements of counsel and accountants for AER and all legal fees and
disbursements and other expenses of complying with state securities or blue  sky
laws  of  any  jurisdictions in which the securities to be  offered  are  to  be
registered  or  qualified. Fees and disbursements not expressly  included  above
shall  be borne pro rata by the Purchaser and the Third Party Shareholders whose
shares are included in such registration statement.
     4.  Section 4(e) of the Agreement is hereby amended to read in its entirety
as follows:

     (e)   Indemnification,  Etc.   In  the event  that  shares  are  registered
pursuant  to  Section  4(a) or 4(c), Purchaser and any Third  Party  Shareholder
registering  shares  of  Common  Stock, as applicable,  and  AER  shall  execute
reasonable  and  customary underwriting, indemnification and lock-up  agreements
relating  to  such  registration and shall undertake  reasonable  and  customary
registration procedures.

     5.    Section  8(c)  of  the Agreement is hereby amended  to  read  in  its
entirety as follows:

     (c)   Assignment.  Except in the case of a transfer permitted under Section
5(a),  no assignment or transfer by Purchaser or any Third Party Shareholder  of
their  respective rights and obligations under this Agreement shall be  made  by
merger  or  other  operation of law or otherwise except with the  prior  written
consent  of AER. This Agreement is binding upon the parties and their successors
and  assigns  and  inures  to  the benefit of the parties  and  their  permitted
successors  and  assigns and, when appropriate to effect the binding  nature  of
this  Agreement for the benefit of the other parties, of any other successor  or
assign.

     6.   Except  as  amended hereby, the Agreement remains in  full  force  and
effect.

     If  you  are in agreement with the foregoing, please so indicate by signing
this letter in the space provided below.

                                   Sincerely,
