The Registrant hereby amends in its entirety its current report on Form 8-K

Item 2. Acquisition or Disposition of Assets.

On April 22, 1999, SGI International (the "Company") executed an agreement with 
Bluegrass Coal Development Company ("Bluegrass"), Wyoming Coal Technology, Inc. 
and Americoal Development Company ("Americoal"), wholly owned subsidiaries of
AEI Resources ("AEI"), to purchase Bluegrass' 50% interest in the Liquids From
Coal ("LFC") Technology; the ENCOAL corporation, which owns the ENCOAL LFC
demonstration plant; certain existing permits necessary to build an LFC plant
near Gillette, Wyoming; and all other tangible and intangible LFC assets.

The consideration to be paid by the Company for the acquisition of the above 
described assets consists of a $2 million dollar promissory note with interest 
thereon at the prime rate due in five years, the waiver by Mitsubishi Heavy 
Industries of a $1.13 million invoice due from Bluegrass and the assumption of 
obligations attendant to ownership of the ENCOAL Corporation. The acquisition 
also calls for a release of all claims between the parties and finalizes the 
dissolution of the TEK-KOL Partnership. The total consideration to be paid was 
determined through arms length negotiations between representatives of the 
Company and AEI. 

Neither the Company, AEI, nor any of their affiliates had, nor to the knowledge
of Company or AEI did any director or officer or any associate of any such 
director or officer of Company, have, any material relationship with AEI prior 
to the Sale.

The closing of the acquisition is conditioned upon, among other things, the
financing of certain improvements to the ENCOAL plant, the completion of both
fuel supply and product sale agreements, the assumption or waiver of certain
bond obligations, the waiver by Mitsubishi Heavy Industries of the $1.13 million
invoice due from Bluegrass and certain other conditions specified in the 
agreement.

The assets to be acquired by the Company have been used to provide upgraded coal
and coal liquids to various utilities and industrial customers. The Company
intends to obtain project financing for the upgrading of the facilities and to
use the assets to produce upgraded coal, for sale to utilities, and coal 
liquids for sale to manufacturers and chemical producers. There can be no
assurance that any financing will be obtained, that the Company will complete
the acquisition or if completed that it will generate any revenue or profits.

Item 7. Financial Statements and Exhibits.

(a) Financial statements of businesses acquired.

The financial statements required by this item will be filed at a later date by
an amendment to this Form 8-K within 60 days after the date the initial
report was required.

(b) Pro forma financial information

The Pro forma financial statements required by this item will be filed at a
later date by an amendment on this Form 8-K within 60 days after the date the 
initial report was required.

therein with others, and further, that there is no present intent to resell or
otherwise dispose of all or any part of the Encoal Stock, the Membership

VIII. COVENANTS. SGI and Sellers each covenant and agree as follows:

A. Approvals. The parties shall promptly apply for and diligently pursue all
consents, authorizations and approvals from governmental authorities and third
parties as shall be necessary or appropriate to permit the consummation of the
transactions contemplated by this Agreement, and shall use all reasonable
efforts to bring about the satisfaction as soon as practicable of all the
conditions set forth in Section 4 to effect the consummation of the transactions
contemplated by this Agreement; provided however, neither party shall be
required to pay any material remuneration to any third party in exchange for
such third party's consent or approval, or to file any lawsuit or other action
to obtain such consent or approval.

B. Records. As used herein, (a) "Taxes" or "Tax" shall mean all taxes, charges,
fees, duties, levies or other assessments imposed by any federal, state, local
or foreign government or any agency or political subdivision thereof, including

federal, state, local and foreign returns, declarations, claims for refunds,
forms, statements, reports, schedules, and information returns or statements,
and any amendments thereof required to be filed with any Tax authority.

With respect to the books and records of Encoal, NuCoal and
TEK-KOL relating to matters prior to the Closing Date, SGI shall retain copies
of all Tax Returns, related schedules and work papers, and all material records
and other documents relating thereto existing on the date hereof or created
through or with respect to taxable periods ending on or before or including the
Closing Date, until six (6) months after the expiration of the statute of
limitations (including extensions) of the taxable years to which such Tax
Returns and other documents relate; and SGI shall cause any person to whom it
may sell or otherwise transfer Encoal or NuCoal (or a significant portion of the
assets of Encoal or NuCoal) to agree to be bound by the provisions of this
Section 8.2 by written acknowledgment delivered to Sellers prior to such sale or
transfer.

SGI and Sellers shall use all reasonable efforts to cooperate
with each other and their respective representatives, in a prompt and timely
manner, in conjunction with any inquiry, audit, examination, investigation,
dispute or litigation involving any Tax Return relating to Encoal, NuCoal or
TEK-KOL filed or required to be filed by or for such entities for any taxable
period beginning before the Closing Date, and relating to any Taxes. Such
cooperation shall include, but not be limited to, making available to Sellers or
SGI, as the case may be, during normal business hours, and within ten (10) days
of any reasonable request therefor, all books, records and information, and the
reasonable assistance of all officers and employees, reasonably required in
connection with any tax inquiry, audit, examination, investigation, dispute,
litigation or any other matter.

C. Tax Returns.

1. Pre-Closing Period. Sellers will prepare and file or cause to be prepared and
filed all Tax Returns relating to Taxes for Encoal and NuCoal required to be
filed for any taxable period that ends on or before the Closing Date
("Pre-Closing Tax Period"). Sellers will pay or cause to be paid all Taxes
required to be paid with respect to any Pre-Closing Tax Period. If required by
applicable law, Sellers will deliver to SGI for signing and filing any Tax
Returns relating to income tax of Encoal or NuCoal with respect to any
Pre-Closing Tax Period (including any short or stub period) that have not been
filed prior to the Closing Date. Sellers will pay all Taxes required to be paid
with respect to such Tax Returns for any Pre-Closing Tax Period.

2. Post-Closing Period. SGI will prepare and file or cause to be prepared and
filed all Tax Returns for Encoal or NuCoal that are required to be filed for all
Tax periods which begin on and continue after the Closing Date. SGI will pay or
cause to be paid all Taxes required to be paid with respect to such Tax Returns.

With respect to any Tax period that would otherwise
include but not end on the Closing Date, to the extent permissible
pursuant to applicable law, Sellers will, and SGI will cause Encoal or
NuCoal to: (a) take all steps which are or may be reasonably necessary,
including, without limitation, the filing of elections or returns with
applicable Tax authorities, to cause such period to end on the Closing
Date; or (b) if clause (a) is inapplicable, to the extent permitted by
applicable law, report the operations of Encoal or NuCoal only for the
portion of such period ending on or immediately before the Closing Date
in a combined, consolidated, or unitary Tax Return filed by Sellers,
notwithstanding that such Tax period does not end on the Closing Date.
If clause (b) applies to a Tax period of Encoal or NuCoal, the portion
of such Tax period included in such return filed by Sellers will be
treated as a Pre-Closing Tax Period described in Section 8.3.1;
provided, however, that SGI shall be responsible for filing all Tax
Returns with respect to all such straddle periods. If neither clause
(a) nor (b) is applicable, then SGI and Encoal and NuCoal shall prepare
and file the appropriate Tax Returns, SGI shall pay any Taxes with
respect thereto, and Sellers shall reimburse SGI for the portion of any
income Taxes shown as due and payable thereon that relate to the
portion of such straddle period that ends on the Closing Date.

3. Cooperation. To assist Sellers in the preparation of all Tax Returns that
Sellers are required to prepare pursuant to this Section 8.3, SGI will prepare
and deliver, or cause Encoal or NuCoal to prepare and deliver, Sellers' standard
Federal and state tax return data gathering packages relating to Encoal or
NuCoal not later than thirty (30) days following receipt of such packages from
Sellers (or sooner, to the extent practicable). In addition to providing such
packages, SGI will promptly provide or cause to be provided to Sellers such
other information as Sellers may reasonably request (including access to books,
records and personnel) in order for the operations of Encoal or NuCoal to be
properly reported in such Tax Returns, for the preparation for any Tax audit, or
for the prosecution or defense of any claim, suit or proceeding relating to
Taxes.

4. Credits and Adjustments. SGI will pay or cause to be paid to Sellers all
refunds, off-sets or credits (including any interest thereon) of Taxes
attributable to Taxes paid by Sellers, Encoal or NuCoal with respect to any
Pre-Closing Tax Period. Sellers will pay or cause to be paid to SGI all refunds,
offsets or credits of Taxes (including any interest thereon) received by Sellers
after the Closing Date and attributable to Taxes paid by SGI that accrued with
respect to a period after the Closing Date. Such payment will be made to Seller
or SGI, as the case may be, within ten (10) days after receipt of any such
refund from or allowance of such credit by the relevant Tax authority.

In the event any adjustment is made or proposed by a Taxing
authority with respect to any Tax subject to this Section 8.3, the person
ultimately responsible for paying any additional Tax (the "Controlling Party"),
shall have the right to contest, litigate, compromise and settle such tax
contest with respect thereto. The Controlling Party shall keep the other party
fully informed as to all significant matters relating to such tax contest and
shall permit the other party and counsel of its choice to participate in any
such contest, litigation, compromise or settlement of any adjustment in such tax
contest. All costs, including legal and accounting expenses, of any tax contest
are to be borne by the party incurring such costs.

D. Insurance. The parties agree that no insurance policy maintained by Sellers
with respect to any of the assets, properties or operations of Encoal, NuCoal
and/or TEK-KOL, including the LFC Property and the Encoal Facilities, shall
cover such properties or operations after the Closing Date, and all benefits and
coverage under each such insurance policy shall terminate at midnight on the
Closing Date. Following the Closing Date, SGI shall be responsible for obtaining
and maintaining any and all insurance policies and coverages in respect of
Encoal, NuCoal, TEK-KOL and their respective assets, properties, operations and
liabilities.

E. Liabilities. SGI hereby acknowledges and agrees that Sellers shall have no
obligations or liabilities (including without limitation any loss, damage,
injury or death, whether known or unknown, asserted or unasserted, absolute or
contingent, accrued or unaccrued, liquidated or unliquidated, whether due or to
become due, regardless of when asserted or arising) (collectively,
"Liabilities") for or with respect to Encoal, NuCoal or TEK-KOL, whether
accruing prior to, on, or after the Closing, and SGI shall indemnify, defend and
hold harmless Sellers from and against, and pay and reimburse Sellers for, all
such Liabilities to the extent Sellers or any of their respective affiliates
shall become liable therefor or any party shall have alleged that Sellers or any
of their respective affiliates is liable therefor.

F. Further Assurances. From time to time, each of the parties hereto will, at
their own cost and expense, execute and deliver such further instruments and
will take such other actions as SGI or Sellers, as the case may be, may
reasonably request in order to effectuate the purposes of this Agreement and to
carry out the terms hereof.

IX. DUE DILIGENCE. SGI shall have a period of 60 calendar days from the
Effective Date to perform due diligence with respect to the matters described in
this Agreement. SGI shall immediately begin to perform its due diligence and
Sellers shall cooperate with SGI in performing the investigation of material
facts relative to this transaction. In order to assist SGI in performing its due
diligence, Sellers shall provide SGI with available financial statements of
Encoal and NuCoal for the years ended December 31, 1996, December 31, 1997,
December 31, 1998, as well as all federal and state tax returns for those years.

X. TERMINATION. This Agreement may be terminated in writing at any time after
the passage of 150 calendar days from the Effective Date: (i) by SGI, if it
determines that there are material legal, financial or personnel problems
associated with Encoal or NuCoal or if it determines it has not been possible to
satisfy the SGI Conditions; or (ii) by Bluegrass or Americoal, if either
determines that the Sellers' Conditions have not been satisfied by the date
which is 150 calendar days from the Effective Date, and the parties do not agree
on an extension or modification to avoid or waive such Sellers' Condition(s),
provided that nothing herein shall obligate either Bluegrass or SGI to agree on
an extension or modification to avoid or waive any or all of Seller's
Conditions.

If, for any reason set forth herein this Agreement is
terminated, the parties agree to proceed with dissolution of TEK-KOL and
liquidation of its assets pursuant to the TEK-KOL Partnership Agreement and
applicable law. The parties further agree that upon execution and delivery of
this Agreement to each other, they will also execute a Release in the form
contemplated by Section 3.3, and including each of Sellers' and SGI's waiver,
release and covenant not to sue the other, or their respective affiliates,
directors, officers, employees, or agents, with respect to any disposition of
the Encoal Facilities by Sellers, in the event this Agreement is terminated,
including without limitation any expansion, improvement, refinement, redesign,
refitting, demolition, dismantlement, and/or relocation of all or any part of
the Encoal Facilities (the "Termination Release"). The Termination Release shall
be in the form of Exhibit 10 hereto. Upon execution of this Agreement by all
parties, duplicate originals of the Termination Release shall be executed and
deposited by the parties into an escrow account with the escrow agent identified
in Exhibit 10. Such Termination Releases shall be released by the escrow agent
to the respective parties (one original to SGI and one original to Sellers) upon
the written certification by either SGI or Sellers to the escrow agent that this
Agreement has terminated.
The parties shall share equally the fees of the escrow agent.

Upon any termination of this Agreement, the parties shall have
no further liability or obligation to each other arising out of this Agreement.

XI. RETURN OF MATERIALS. In the event that the Agreement is terminated in
accordance with the terms herein, then each party shall return to the other
party all documents and materials obtained from the other. Further, each party
shall cause its employees and agents to sign confidentiality agreements relative
to the information discovered in performing the due diligence.

XII. CONFIDENTIALITY. The parties may each obtain confidential and proprietary
information about the other from and after the Effective Date of this Agreement.
Each party shall hold that information in strictest confidence and shall not
disclose it to any third party at any time without the specific consent of the
other party. The parties shall execute the confidentiality agreement in the form
attached hereto as Exhibit 12, which shall be effective as of the Effective
Date.

XIII. PUBLICITY. No announcements relative to the Agreement shall be made by
either party without the prior review and approval of the other party, which
approval shall not be unreasonably withheld, delayed or conditioned, except to
the extent any such announcement is required by applicable law. Notwithstanding
the above, Sellers acknowledge that SGI will be required to make a publicity
announcement relative to the execution of this Agreement and Sellers will
cooperate with SGI in its making that announcement, provided SGI has allowed AEI
to review the announcement prior to being made public and AEI has given their
approval, not to be unreasonably withheld.

XIV. INDEMNIFICATION.

A. Indemnity by Sellers. After Closing, Sellers shall indemnify, defend and hold
harmless SGI and its respective directors, officers, employees and agents from

Agreement.

B. Indemnity by SGI. After Closing, SGI shall indemnify, defend and hold

C. Claim Notice. No right to indemnification under this Section 14 shall be
available to an indemnitee with respect to a claim, action, demand, suit or
proceeding to be indemnified hereunder (collectively, "Claim") unless the
indemnitee shall have delivered to the indemnitor, within 10 calendar days of
obtaining any knowledge or information about the Claim, a notice describing in
reasonable detail the facts giving rise to such Claim (a "Claim Notice") and
stating that the indemnitee intends to seek indemnification for such Claim from
the indemnitor pursuant to this Section 14.

D. Defense of Claims. Upon receipt of a Claim Notice from an indemnitee with
respect to any Claim, the indemnitor shall have the right to assume and control
the defense thereof (and any related settlement negotiations) with counsel
reasonably satisfactory to such indemnitee, and the indemnitee shall cooperate
in all reasonable respects in such defense. The indemnitee shall have the right
to employ separate counsel at such indemnitee's expense in any action or claim
and to participate in the defense thereof, provided, however, that the
reasonable fees and expenses of counsel employed by the indemnitee shall be at
the expense of the indemnitor if such counsel is retained pursuant to the
following sentence or if the employment of such counsel has been specifically
authorized in writing by the indemnitor. If the indemnitor does not notify the
indemnitee within thirty (30) days after receipt of the Claim Notice of its
intention to assume the defense of such Claim, the indemnitee shall have the
right to defend the claim with counsel of its choosing reasonably satisfactory

of any claim at any time prior to settlement or final determination thereof.
Notwithstanding anything to the contrary contained in this Section 14.4, (a) the
indemnitee shall have the right to employ separate counsel at its own expense if
there shall be available one or more defenses or one or more counterclaims
available to the indemnitee which conflicts with one or more defenses or one or
more counterclaims available to the indemnitor, and (b) the indemnitor shall not
be entitled to control (but shall be entitled to participate at its own expense
in the defense of), and the indemnitee shall be entitled to have sole control
over, the defense or settlement of any Claim to the extent such Claim seeks an
order, injunction, non-monetary or other equitable relief against the indemnitee
which, if successful, could result in a material adverse effect upon the
business, financial condition, results of operations or assets of the
indemnitee. The indemnitee shall send a written notice to the indemnitor of any
proposed settlement of any claim, which settlement the indemnitor may reject, in
its reasonable judgment, within thirty (30) days of receipt of such notice.
Failure to reject such notice within such 30-day period shall be deemed an
acceptance of such notice.

the others, as reasonably requested, all information, records and documents
relating to all Claims and shall preserve all such information, records and

hereto have been unable to settle or agree upon within a period of ten (10)
calendar days after the dispute or disagreement arises, each party shall
nominate a senior officer of its management to meet at an agreed time and place
not later than ten (10) calendar days after the dispute or disagreement has
arisen to attempt to resolve such dispute or disagreement. Should a resolution
of such dispute or disagreement not be obtained within fifteen (15) calendar
days after the meeting of senior officers for such purpose, either party may
then by notice to the other submit the dispute to binding arbitration in
accordance with the provisions of Section 17.2.

one neutral arbitrator; the third arbitrator, who shall be the chairman of the
panel, shall be selected by the two party-appointed arbitrators. The claimant
shall name its arbitrator in the demand for arbitration and the responding party
shall name its arbitrator within thirty (30) calendar days after receipt of the
demand for arbitration. The third arbitrator shall be named within thirty (30)
calendar days after the appointment of the second arbitrator. The American
Arbitration Association shall be empowered to appoint any arbitrator not named

sale transactions of this type. Prior to the commencement of hearings, each of

The decision of the arbitrators shall be final and binding
upon the parties without the right of appeal to the courts. In deciding the
substance of any such claim, dispute or disagreement, the arbitrators shall
apply the substantive laws of the State of Wyoming; provided, however, the
arbitrators shall have no authority to award consequential damages, incidental
or punitive damages under any circumstances (whether it be exemplary damages,
treble damages, or any other penalty or punitive type of damages) regardless of

The award rendered by the arbitrators shall be final and judgment thereon may be
entered by any court having jurisdiction thereof. The costs and expenses of the
arbitration (including reasonable attorneys' fees) will be borne by the losing
party as determined by the arbitrators, unless the arbitrators determine that it
would be manifestly unfair to honor this agreement of the parties with respect
to awarding such costs and attorneys' fees, and determine a different allocation
of costs and attorneys' fees.

Except as may be required by law, neither a party nor an
arbitrator may disclose the existence, content, or results of any arbitration
hereunder without the prior written consent of all parties to the arbitration.
Arbitration proceedings shall be conducted in English.

This Note is referred to in that certain Acquisition Agreement among

in certain royalties of Maker.

All payments on this Note shall be applied first to the payment of

shall be applied to reduction of the principal balance. The privilege to prepay
all or any part of the principal sum from time to time without penalty is hereby
reserved to Maker, provided that any such principal prepayment shall be
accompanied by all interest then accrued.

At the option of Payee, the entire unpaid principal sum and all accrued
interest shall become immediately due and payable, without notice or demand,
upon the occurrence of any one or more of the following events of default: (a)

then due shall, from and after the date of such default, bear interest at the
rate per annum equal to two percentage points in excess of the rate of interest
herein provided for at the time of default, thereafter compounded annually at
December 31. Maker hereby agrees to pay reasonable attorneys' fees and all other
reasonable costs and expenses incurred, after an event of default, in the
enforcement of this Note, the enforcement of any security interest with respect
to this Note, and the collection of amounts due hereunder, whether such
enforcement or collection is by court action or otherwise.

construction, effect and in all other respects by the laws and decisions of the
State of Wyoming.

nonpayment or dishonor, protest and notice of protest, and agrees to any
extension of time of payment and partial payments before, at, or after maturity.
No renewal or extension of this Note, no release or surrender of any security
for this Note, no release of any person liable hereon, no delay in the
enforcement hereof, and no delay or omission in exercising any right or power
hereunder, shall affect the liability of Maker. No delay or omission by Payee in
exercising any power or right hereunder shall impair such right or power or be
construed to be a waiver of any default, nor shall any single or partial
exercise of any power or right hereunder preclude any or full exercise thereof
or the exercise of any other right or power. Each legal holder hereof shall have
