ITEM 1.  SECURITY AND ISSUER.

         This Statement on Schedule 13D relates to shares of Common Stock,
$.0001 par value per share ("Common Stock") of Asche Transportation Services,
Inc., a Delaware corporation (the "Issuer"), with principal offices located at
10214 North Mount Vernon Road, Shannon, Illinois 61078.

ITEM 2.  IDENTITY AND BACKGROUND.

         (a)-(c) This Schedule 13D is being filed by Churchill Environmental &

Exhibit 7.1 hereto.

         CEIP, organized as a Delaware limited partnership, is a private
investment partnership fund with offices in Minneapolis, Minnesota and New York
City, New York. CEIP provides bridge senior debt, subordinated debt, preferred
stock and common equity for owner recapitalizations, management buyouts, capital

investment transactions aggregating $23,250,000. CEIP is the fifth investment

         CCE is a Delaware limited liability company. CCE is the general partner
of CEIP, and it's principal business is serving as the general partner for CEIP.
CCE's principal executive offices are located at 3100 Metropolitan Centre, 333

         CCI is a Minnesota corporation. CCI is the managing agent of CCE. CCI's

duties associated with the responsibilities of CCE, as the general partner of
CEIP and serving in a similar capacity for other private investment partnership

Centre, 333 South 7th Street, Minneapolis, Minnesota, 55402. As of September
16, 1999, John J. Fauth owns 72.4% of the outstanding equity of CCI.

         Schedule I hereto sets forth the name, business address, present
principal occupation or employment, and the name, principal business and address
of any corporation or other organization in which such employment is conducted,
for each of CCE's and CCI's directors and executive officers.

         (d)-(e) During the last five years, none of the Reporting Persons, nor,
to the best knowledge of the Reporting Persons, any of the persons listed on
Schedule I hereto: (i) has been convicted in a criminal proceeding (excluding
traffic violations or similar misdemeanors); or (ii) was a party to a civil
proceeding of a judicial or administrative body of competent jurisdiction and as
a result of such proceeding was or is subject to a judgment, decree or final
order enjoining further violations of, or prohibiting or mandating activities
subject to, Federal or State securities laws or finding any violation with
respect to such laws.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         CEIP and the persons set forth on Schedule II hereof (collectively,
referred to herein as the "Stockholders"), have entered into the Voting
Agreements described in Item 4 below. As a result, CEIP, CCE, and CCI may be
deemed to have beneficial ownership of approximately 47% of the Issuer's Common
Stock.

ITEM 4.  PURPOSE OF THE TRANSACTION.

         On August 17, 1999, CEIP, the Issuer and certain of its subsidiaries
entered into a Stock Purchase Agreement (the "Stock Purchase Agreement"). The
Stock Purchase Agreement provides, among other things, that the Issuer will sell
to CEIP (the "Churchill Transaction") either (A) 2,666,667 shares of Common
Stock at a price of $4.50 per share in cash if the average closing price of the
Common Stock on the NASDAQ for the ten consecutive trading days immediately
preceding the closing date of the Churchill Transaction is less than $5.00 per
share, or (B) 2,400,000 shares at a price of $5.00 per share in cash if the
average closing price of the Common Stock on the NASDAQ for the ten consecutive
trading days
<PAGE>   6
immediately preceding the closing date of the Churchill Transaction is equal to,
or greater than $5.00 per share (the "Initial Shares"). The Stock Purchase
Agreement also requires the Issuer to issue to CEIP additional shares of Common
Stock (the "Additional Shares") if the highest average closing price on the
NASDAQ of the Company's Common Stock for any ten consecutive trading days
beginning on September 1, 2000 and ending on November 1, 2000 (the "Measurement
Period") is less than (i) $6.50 (if the initial purchase price for the Common
Stock is $4.50 per share) or (ii) $7.00 (if the initial purchase price for the
Common Stock is $5.00 per share). The Stock Purchase Agreement further provides
that prior to the closing of the Churchill Transaction, the Issuer shall take
all steps necessary to increase the size of its Board of Directors (the "Board")
from nine (9) members to fifteen (15) members and to elect four (4) new members
to the Board who shall take office effective upon the closing of the Churchill
Transaction and shall be designated by CEIP (the "Churchill Designees"). The
Stock Purchase Agreement and the Churchill Transaction are conditioned upon,
among other things, the approval of the stockholders of the Issuer and the
Issuer entering into a Registration Rights Agreement with CEIP and an Advisory
Services Agreement with CCI. Pursuant to the Registration Rights Agreement, the
Issuer would grant CEIP demand and piggyback registration rights with respect to
the shares of Common Stock acquired by CEIP in the Churchill Transaction.
Pursuant to the Advisory Services Agreement, the Issuer would retain CCI to
provide management and financial advisory services to the Issuer and its
subsidiaries for a monthly management fee.

         In connection with, and as a condition to, the execution and delivery
of the Stock Purchase Agreement, CEIP and the Stockholders entered into voting
agreements, each dated August 17, 1999 (each a "Voting Agreement," and
collectively, the "Voting Agreements"). The Voting Agreements relate to an
aggregate 2,763,566 shares of the Issuer's Common Stock owned by the
Stockholders which represents approximately 47% of the shares of Common Stock
outstanding. Pursuant to the Voting Agreements each Stockholder has agreed,
among other things, that for so long as the Stockholder holds any shares of
Common Stock, at any meeting of the holders of Common Stock, however called, or
in connection with any written consent of the holders of Common Stock, the
Stockholder shall vote (or cause to be voted) all shares of Common Stock held of
record or beneficially owned by the Stockholder (collectively, the "Shares"):
(i) in favor of an amendment to the Issuer's charter which would increase the
Issuer's authorized capital stock from 10,000,000 to 20,000,000 shares; (ii) in
favor of the Churchill Transaction and the execution and delivery by the Issuer
of the Stock Purchase Agreement and the agreements related thereto, the approval
of the terms thereof and each of the other transactions and actions contemplated
thereby (and the matters related to the consummation thereof); (iii) in favor of
the appointment of the Churchill Designees to the Board, as contemplated by the
Stock Purchase Agreement; (iv) in favor of amendments to the Issuer's charter
and by-laws which would increase the size of the Board to a maximum of fifteen
(15) members; (v) against any action or agreement that would result in a breach
in any respect of any covenant, representation or warranty or any other
obligation or agreement of the Issuer under the Stock Purchase Agreement or the
agreements related thereto or of the Stockholder under the Voting Agreement or
that would result in any of the conditions to the obligations of the Issuer
under the Stock Purchase Agreement not being fulfilled; and (vi) until the
Churchill Transaction shall have been duly approved by the holders of Common
Stock, and except as otherwise agreed to in writing in advance by CEIP, against
each of the following actions (other than the transactions contemplated by, or
required by, the Stock Purchase Agreement and the agreements related thereto):
(A) any extraordinary corporate transaction, such as a merger, consolidation or
other business combination involving the Issuer or its subsidiaries; (B) a sale,
lease or transfer of a material amount of assets of the Issuer or its
subsidiaries, or a reorganization, recapitalization, dissolution or liquidation
of the Issuer or its subsidiaries; (C) any change in a majority of the persons
who constitute the board of directors of the Issuer; (D) any change in the
present capitalization of the Issuer or any amendment to the Issuer's charter or
by-laws; (E) any other material change in the Issuer's corporate structure or
business; or (F) any other action involving the Issuer or its subsidiaries which
is intended, or could reasonably be expected to impede, interfere with, delay,
postpone, or materially adversely affect the transactions contemplated by the
Stock Purchase Agreement, the agreements related thereto and the Voting
Agreements. Each of the Voting Agreements, other than the Voting Agreement
executed by James A. Jalovec, terminates upon the termination of the Stock
Purchase Agreement. Mr. Jalovec's Voting Agreement terminates on January 1, 2000
(if the Churchill Transaction shall not have occurred on or before December 31,
1999), or the end of the Measurement Period (if the closing of the Churchill
Transaction shall have occurred on or before December 31, 1999).

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

         (a)-(b) As of September 16, 1999, the Reporting Persons owned no shares
of Common Stock. However, as of September 16, 1999, under the definition of
"beneficial ownership" as set forth in Rule 13d-3 of the Securities Exchange Act
of 1934, as amended (the "Exchange Act"), CEIP, CCE and CCI may be deemed to
have beneficial ownership of the Shares pursuant to the Voting Agreements, which
require the Stockholders to vote in favor of the Churchill Transaction and the
Stock Purchase Agreement. CEIP, by virtue of the Voting Agreements, has the
power to direct the voting of the Shares. CCE, as the general partner of CEIP,
may be deemed to have the power to direct the voting of the Shares. CCI, as the
managing agent of CCE, may be deemed to have the power to direct the voting of
Shares. The Shares constitute approximately 47% of the shares of Common Stock
outstanding.

         Neither the filing of this Schedule 13D nor any of its contents shall
be deemed to constitute an admission that the Reporting Persons are the
beneficial owners of the Common Stock referred to in this paragraph for purposes
of Section 13(d) of the Exchange Act or for any other purpose, and such
beneficial ownership is expressly disclaimed.

         (c)-(e)  Not applicable.

ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
         TO SECURITIES OF THE ISSUER.

         Except as described herein, to the best knowledge of the Reporting

thereof, respectively, and the term NASDAQ (including for the purposes of the
definition of Trading Day) will be deemed to refer to the exchange/trading
system on which such securities are traded and it shall be a condition to the

closing of the purchase and sale of the Initial Shares (the "Closing") shall be
held at the offices of Rogers & Wells LLP, 200 Park Avenue, New York, New York,
at 10:00 a.m. local time, on September 24, 1999, or, at the option of the
Purchaser, within thirty (30) days after the satisfaction or waiver of the
conditions contained in Sections 6 and 7.

     (b) On the Closing Date, Purchaser shall pay the Purchase Price in
immediately available funds, by wire transfer to an account designated by the
Company not less than two (2) Business Days prior to the Closing Date or, if the
Company fails to so designate an account within the required time, by delivery
of a certified or official bank check payable to the order of the Company.

     (c) Simultaneously with Purchaser's payment of the Purchase Price, the
Company shall deliver to Purchaser a certificate representing the Initial
Shares.

cause to be nominated, and shall use its best efforts to cause to be elected, a
number of members of the Company's Board of Directors (rounded up to the next
whole number) (such members to be designated by the holders of a majority of the
shares of Common Stock beneficially owned by Purchaser and its successors and
assigns) which bears the same proportion to the total number of members of the
Company's Board of Directors as the number of shares of Common Stock then
beneficially owned in the aggregate by Purchaser and its successors and assigns
bears to the total number of shares of Common Stock then issued and outstanding.
The Company shall upon the initial election or appointment of the Purchaser
Designees to the Company's Board of Directors, and at the conclusion of each
annual meeting of the Board thereafter, automatically grant to each of the
Purchaser Designees Formula Options (as defined in the Asche Transportation
Services, Inc. Stock Option Plan (the "Stock Option Plan")) to purchase five
thousand (5,000) shares of Common Stock. Further the Company shall, so long as
the Purchaser Designees serve on the Company's Board of Directors, cause to

                                       13

     Section 10. Indemnification.

     10.01. Indemnity by the Company and the Subsidiaries. (a) Subject to the
provisions of this Section 10, the Company and each Subsidiary jointly and
severally indemnify and hold Purchaser and its respective officers, directors,
stockholders, managers, agents, employees, representatives, affiliates,
successors and assigns, harmless from and against any and all damage, loss
(including loss of value), cost, obligation, claims, demands, assessments,
settlements, judgments or liability (whether based on contract, tort, product
liability, strict liability or otherwise), including Taxes, and all expenses
(including interest, penalties and attorneys' and

                                       18
<PAGE>   22
accountants' fees and disbursements) (collectively referred to herein as
"Damages") incurred in litigation or otherwise, and any investigation relating
thereto, by any of the above-named persons, directly or indirectly, arising from
or in connection with: (i) the inaccuracy, untruth or incompleteness, as of the
date made or deemed made, of any representation or warranty by the Company or
any Subsidiary in this Agreement or in any other agreement, certificate
(including, without limitation, the certificates delivered by the Company and
each Subsidiary pursuant to Section 6), schedule, exhibit or writing required to
be delivered to Purchaser pursuant to this Agreement; (ii) any breach of or
failure to perform any covenant or agreement made by the Company or its
Subsidiaries in this Agreement; and (iii) any untrue or alleged untrue statement
of a material fact contained in the Proxy Statement or in any amendment or
supplement thereto, or arising out of or based upon any omission or alleged
omission of a material fact required to be stated therein or necessary to make
the statement therein not misleading, except for the section in the Proxy
Statement titled "The Purchaser."

     10.02. Purchaser's Indemnity. Subject to the provisions of this Section 10,
Purchaser, from and after the Closing Date, shall indemnify and hold the Company
and the Subsidiaries, and their respective officers, directors, stockholders,
agents, employees, representatives, affiliates, successors and assigns, harmless
from and against any Damages incurred in litigation or otherwise, and any
investigation related thereto, by the Company or any Subsidiary, directly or
indirectly, arising from or in connection with: (a) the inaccuracy, untruth or
incompleteness, as of the date made or deemed made, of any representation or
warranty by Purchaser in this Agreement or in any other agreement, certificate
(including without limitation the certificates delivered by Purchaser pursuant
to Section 7), schedule, exhibit or writing delivered to the Company or any
Subsidiary pursuant to this Agreement; and (b) any breach of or failure to
perform any covenant or agreement made by Purchaser in this Agreement.

     10.03. Procedure. No claim for indemnification shall be valid unless made
prior to the expiration (pursuant to Section 9) of the applicable
representation, warranty or covenant on which it is based. All claims for
indemnification by a party under this Section 10 (the party claiming
indemnification and the party against whom such claims are asserted being
hereinafter called the "Indemnified Party" and the "Indemnifying Party,"
respectively) shall be asserted and resolved as follows:

     (a) In the event that any claim or demand for which an Indemnifying Party
would be liable to an Indemnified Party hereunder is asserted against or sought
to be collected from such Indemnified Party by a third party, such Indemnified
Party shall with reasonable promptness give notice (the "Claim Notice") to the
Indemnifying Party of such claim or demand, specifying the nature of and
specific basis for such claim or demand and the amount or the estimated amount
thereof to the extent then feasible (which estimate shall not be conclusive of
the final amount of such claim and demand); provided, however, that no failure
to give, or delay in giving, any such Claim Notice shall excuse or diminish the
Indemnifying Party's obligations to the Indemnified Party under this Section 10,
unless such failure or delay is prejudicial to Indemnifying Party. The
Indemnifying Party shall have ten (10) days from the date the Claim Notice is
given in accordance with Section 8 of this Agreement (the "Notice Period") to
notify the Indemnified Party (i) whether or not it disputes the liability of the
Indemnifying Party to the Indemnified Party hereunder with respect to such claim
or demand, and (ii) whether or not it desires, at the cost and expense of the
Indemnifying Party, to defend the Indemnified Party against such claim or
demand; provided, however, that any Indemnified Party is hereby authorized, but
is not obligated, prior to and during the Notice Period, to file any motion,
answer or other pleading that it shall deem necessary or appropriate to protect
its interests or those of the Indemnifying Party. If the Indemnifying Party
notifies the Indemnified Party within the Notice Period that it desires to
defend the Indemnified Party against such claim or demand, the Indemnifying
Party shall, subject to the last sentence of this paragraph, have the right to
control the defense against the claim by all appropriate proceedings and any
settlement negotiations. If the Indemnifying Party assumes the defense of a
proceeding, (i) no compromise or settlement of such claims may be effected by
the Indemnifying Party without the Indemnified Party's consent (such consent not
to be unreasonably withheld or delayed) unless the sole relief provided is
monetary damages that are paid in full by the Indemnifying Party; and (ii) the
Indemnified Party will have no liability with respect to any compromise or
settlement of such claims effected without its consent. If the Indemnified Party
desires to participate in, but not control, any such defense, it may do so at
its sole cost and expense. If the Indemnifying Party fails to respond to the
Indemnified Party within the Notice Period or otherwise elects not

                                       19
<PAGE>   23
to defend the Indemnified Party, or after electing to defend fails to
commence or diligently pursue such defense, then the Indemnified Party shall
have the right, but not the obligation, to undertake or continue such defense
and to compromise or settle the claim or other matter, all on behalf, for the
account and at the risk of the Indemnifying Party.

     (b) If requested by the Indemnifying Party, the Indemnified Party agrees,
at the Indemnifying Party's expense and upon presentation of adequate security
for the payment of such expenses, to cooperate with the Indemnifying Party and
its counsel in contesting any claim or demand which the Indemnifying Party
elects to contest, or, if appropriate and related to the claim in question, in
making any counterclaim against any person asserting the third-party claim or
demand, or any cross-complaint against any person.

     (c) If any Indemnified Party should have a claim against the Indemnifying
Party hereunder which does not involve a claim or demand being asserted against
or sought to be collected from it by a third party, the Indemnified Party shall
send a Claim Notice with respect to such claim to the Indemnifying Party. If the
Indemnifying Party disputes such claim, such dispute shall be resolved by
litigation in an appropriate court of competent jurisdiction described in
Section 12.02. If the Indemnifying Party does not dispute such claim, then the
Indemnifying Party shall pay to the Indemnified Party the amount of such claim
within thirty (30) days after receipt of such Claim Notice.

     (d) In connection with the matters for which indemnification is sought
hereunder (i) the Company agrees to give Purchaser and its representatives
reasonable access during regular business hours and upon five (5) days' prior
written notice to the Company, to the books, records and employees of the
Company to the extent such reasonably relate to the matters to which the Claim
Notice relates and (ii) Purchaser agrees to give the Company and its
representatives reasonable access, during regular business hours and upon five
(5) days' prior written notice to Purchaser, to the books, records and employees
of Purchaser to the extent they reasonably relate to the matters to which the
Claim Notice relates.

     10.04. Indemnification not Affected by Knowledge. The right to
indemnification, payment for Damages or any other remedy based on any inaccuracy
in or breach of any representation, warranty, covenant or agreement contained in
this Agreement or in any document, certificate or other papers delivered
pursuant to this Agreement, will not be affected by any investigation conducted
with respect to, or any knowledge acquired (or capable of being acquired) at any
time, whether before or after the execution and delivery of this Agreement or
the Closing Date, with respect to, the accuracy or inaccuracy of or compliance
with, any such representation, warranty, covenant or obligation.

     Section 11. Termination.

     11.01. Termination. This Agreement may be terminated at any time prior to
the Closing:

     (a) By mutual agreement of the Company and Purchaser;

     (b) By either Purchaser or the Company if the Closing has not taken place
on or before December 31, 1999 or such other date specified by the Purchaser in
accordance with Section 2.03(a), and the failure to consummate the Closing is
not caused by a breach of this Agreement by the party seeking to terminate this
Agreement.

     (c) By the Purchaser if:

          (A) On or before September 13, 1999 (the "Diligence Out Date") the
     Purchaser shall not have completed its due diligence in relation to the
     transactions contemplated by this Agreement in a manner satisfactory to the
     Purchaser in its sole discretion; provided, however, that if the Company or
     any Subsidiary fails to reasonably comply with Section 5.01(a)(iii), the
     Diligence Out Date shall be the Closing Date; or

          (B) The Stockholders fail to duly approve any of the Transactions at a
     meeting duly convened therefor or at any adjournment thereof, and the

     6(n).

     11.02. Effect of Termination. In the event of termination pursuant to
Section 11.01(b) or clause (B) of Section 11.01(c), the Company shall pay to
Churchill Capital, Inc. by wire transfer of immediately available funds to an
account designated by Churchill Capital, Inc. an amount in cash equal to
Purchaser's and Churchill Capital Inc.'s reasonable out-of-pocket expenses
(including legal, accounting, environmental and other professional fees) that
were incurred through the date of termination in connection with the
negotiation, execution and performance of this Agreement and the transactions
contemplated hereby. Notwithstanding the foregoing, if at or prior to the time
of termination pursuant to Section 11.01(b) or clause (B) of Section 11.01(c)
any Person other than Purchaser shall have made an offer or a proposal for a
Competing Transaction and the transactions contemplated by such a Competing
Transaction with such third party are consummated with such third party or a
definitive agreement is entered into with respect to such transaction within
eighteen months after such termination, then the Company shall pay at the
request of Purchaser to Churchill Capital, Inc. as its sole remedy for the
breach hereof, (A) a fee in an amount in cash equal to Seven Hundred Fifty
Thousand Dollars ($750,000) (the "Termination Fee") and (B) an amount in cash
equal to Purchaser's and Churchill Capital Inc.'s reasonable out-of-pocket
expenses (including legal, accounting, environmental and other professional
fees) that were incurred through the date of termination in connection with the
negotiation, execution and performance of this Agreement and the transactions
contemplated hereby. The Termination Fee and payment for out-of-pocket expenses
pursuant to the preceding sentence shall be paid by wire transfer of immediately
available funds to an account designated by Churchill Capital, Inc., and shall
be paid within three Business Days after the earlier of consummation of the
Competing Transaction or entering into of such definitive agreement. The Company
acknowledges that the agreements contained in this Section 11.02 are an integral
part of the transactions contemplated in this Agreement and that, without these
agreements, Purchaser would not enter into this Agreement; accordingly, if the
Company fails to promptly pay the amount due pursuant to this Section 11.02,
and, in order to obtain such payment, Purchaser or Churchill Capital, Inc.,
commences a suit which results in a judgment against the Company for the fee set
forth in this Section 11.02, the Company shall pay to Purchaser its costs and
expenses (including attorneys' fees) in connection with such suit, together with
interest on the amount of the fee at the rate of 12% per annum.

     11.03. No Liability. In the event of a termination of this Agreement
pursuant to Section 11.01, there shall be no liability on the parties hereto or
any of their respective directors, officers, shareholders, members, managers, or
affiliates after such termination, provided, however, that such termination
shall not affect any liability which any party may have hereunder as a
consequence of any breach by any other party of this Agreement prior to such
termination or for the Termination Fee and reimbursement of out-of-pocket
expenses pursuant to Section 11.02.

     (a) Notice. Any party hereto may exercise its right of termination of this
Agreement only by delivering written notice to that effect to the other parties
hereto, provided that such notice is received by the latter party prior to the
Closing.

     Section 12. Miscellaneous.

documents and to perform such other acts as may be necessary or expedient to

     12.04. Attorney's Fees and Costs. If attorney's fees or other costs are
incurred to secure performance of any obligations hereunder, or to establish
damages for the breach thereof or to obtain any other appropriate relief,
whether by way of prosecution or defense, the prevailing party will be entitled
to recover reasonable attorneys' fees and expenses incurred in connection
therewith (which in the case of Purchaser, shall include

                                       21
<PAGE>   25
the reasonable allocation of the costs of its in-house legal services, but
without duplication of the outside legal counsel fees) and interest on any
amount of money determined by any court to be due, at the legal rate in the
State of New York, from the date or dates the court determines that payment
should have been made.

     12.05. Assignment. Neither this Agreement nor any of the rights, interests
or obligations hereunder may be assigned or delegated by the Company, any
Subsidiary or Purchaser without the prior written consent of the other party and
any purported assignment or delegation in violation hereof shall be null and
void, provided, however, that Purchaser may assign all or any part of its
rights, interests and obligations hereunder to (a) any third party in the event
of a sale by Purchaser of all or a portion of the Shares to such third party or
(b) any Affiliate of Purchaser; provided, that no such assignment before the
Closing Date by Purchaser shall relieve Purchaser of its obligations hereunder.

Schedules) sets forth the entire understanding of the parties hereto with
respect to the transactions contemplated hereby and supersede any prior written
or oral understandings with respect thereto, including, without limitation, any
letters of intent. The invalidity or unenforceability of any terms or provisions
hereof shall not affect the validity or enforceability of any other term or
provision hereof. The headings in this Agreement are for convenience of
reference only and shall not alter or otherwise affect the meaning hereof. This
Agreement may be executed in any number of counterparts which together shall
constitute one instrument and shall be governed by and construed in accordance
with laws of the State of New York without giving regard to the principles of
conflicts of law, and shall bind and inure to the benefit of the parties hereto
and their respective successors and permitted assigns.

     12.07. Expenses. Except as otherwise expressly provided in this Agreement,
the Company agrees to pay, without right of reimbursement from Purchaser, the
costs incurred, incident to the preparation and execution of this Agreement and
the Related Agreements and performance of its obligations hereunder, whether or
not the transactions contemplated by this Agreement and the Related Agreements
shall be consummated, including, without limitation, reasonable fees and
disbursements of legal counsel, accountants and consultants employed by the
respective parties in connection with the transactions contemplated by this
Agreement and the Related Agreements.

     12.08. Public Announcements. At all times at or before the Closing, except
as required by law or on the advice of counsel, neither the Company and the
Subsidiaries, on the one hand, and Purchaser on the other hand will issue or
make any release to the press or NASDAQ, or other public disclosure with respect
to this Agreement or the transactions contemplated hereby without the consent of
the other. Except as required by law or NASDAQ, the Company and the
Subsidiaries, on the one hand, and Purchaser on the other hand, will also obtain
the other's prior approval of any press release to be issued immediately
following the Closing announcing the consummation of the transactions
contemplated by this Agreement.

<PAGE>   29

     SECTION 2. Demand Registration.

     (a) The Holder shall have the right at any time by written notice (the
"Demand Notice") given to the Company, to request the Company to register under
and in accordance with the provisions of the Securities Act all or any portion
of the Registrable Shares designated by such Holder; provided, however, that the
aggregate number of Registrable Shares requested to be registered pursuant to
any Demand Notice and pursuant to any related Demand Notices received pursuant
to the following sentence shall be at least 100,000 (subject to adjustment) and
provided, further, however, that such registration shall, at the option of the
Company, be on Form S-3 (or its successor form) if such form is then available
for use by the Company. Upon receipt of any such Demand Notice, the Company
shall promptly notify any other Holders of the receipt of such Demand Notice and
allow them the opportunity to include Registrable Shares held by them in the
proposed registration by submitting their own Demand Notice. In connection with
any Demand Registration in which more than one Holder participates, in the event
that such Demand Registration involves an Underwritten Offering and the managing
underwriter or underwriters participating in such offering advise in writing the
Holders of Registrable Shares to be included in such offering that the total
number of Registrable Shares to be included in such offering exceeds the amount
that can be sold in (or during the time of) such offering without delaying or
jeopardizing the success of such offering (including the price per share of the
Registrable Shares to be sold), then the amount of Registrable Shares to be
offered for the account of such Holders shall be reduced pro rata on the basis
of the number of Registrable Shares to be registered by each such Holder. The
Holders as a group shall be entitled to three Demand Registrations pursuant to
this Section 2 unless any Demand Registration does not become effective, is not
maintained for a period (whether or not continuous) of at least the applicable
period specified in Section 2(c), or where the amount of Registrable Shares to
be offered for the account of such Holders is reduced pro rata as described in
the preceding sentence by more than ten percent (10%), in which case the Holders
will be entitled to an additional Demand Registration pursuant hereto.

     (b) The Company, within thirty (30) days of the date on which the Company
receives a Demand Notice given by Holders in accordance with Section 2(a)
hereof, shall file with the SEC, and the Company thereafter shall use its best
efforts to cause to be declared effective, a Registration Statement on the
appropriate form (subject to the last proviso of the first sentence of Section
2(a)) for the registration and sale, in accordance with the intended method or
methods of distribution, of the total number of Registrable Shares specified by
the Holders in such Demand Notice, which may at the option of the Company
include a "shelf" registration (a "Shelf Registration") pursuant to Rule 415
under the Securities Act (a "Demand Registration").

     (c) The Company shall use commercially reasonable efforts to keep each
Registration Statement filed pursuant to this Section 2 continuously effective
and usable for the resale of the Registrable Shares covered thereby (i) in the
case of a Registration that is not a Shelf Registration, for a period of one
hundred twenty (120) days from the date on which the SEC declares such
Registration Statement effective and (ii) in the case of a Shelf Registration,
continuously from the date on which the SEC declares such Registration Statement
effective, in either case (x) until all the Registrable Shares covered by such
Registration Statement have been sold pursuant to such Registration Statement),
and (y) as such period may be extended pursuant to this Section 2.

     (d) The time period for which the Company is required to maintain the
effectiveness of any Registration Statement shall be extended by the aggregate
number of days of all Holdback Periods (as defined in Section 4) and all
Interruption Periods (as defined in Section 6(k)) occurring during such
Registration and such period and any extension thereof is hereinafter referred
to as the "Effectiveness Period."

     (e) Except to the extent required by agreements with other security holders
of the Company entered into prior to the date of the Stock Purchase Agreement,
the Company shall not include any securities that are not Registrable Shares in
any Registration Statement filed pursuant to this Section 2 without the prior
written consent of the Holders of a majority in number of the Registrable Shares
covered by such Registration Statement, which consent shall not be unreasonably
withheld.

                                        3
<PAGE>   30

     (f) Holders of a majority in number of the Registrable Shares to be
included in a Registration Statement pursuant to this Section 2 may, at any time
prior to the effective date of the Registration Statement relating to such
Registration, revoke such request by providing a written notice to the Company
revoking such request. Notwithstanding such revocation, such request shall be
deemed to be a Demand Registration pursuant to Section 2(a) unless the Holders
of Registrable Shares who revoke such request shall reimburse the Company for
all its out-of-pocket expenses incurred in the preparation, filing and
processing of the Registration Statement; provided, however, that, if such
revocation was based on the Company's failure to comply in any material respect
with its obligations hereunder, such reimbursement shall not be required.

     SECTION 3. Piggyback Registration.

     (a) Right to Piggyback. If at any time after the date hereof the Company
proposes to file a registration statement under the Securities Act with respect
to a public offering of securities of the same type as the Registrable Shares
pursuant to a firm commitment underwritten offering solely for cash for its own
account (other than a registration statement (i) on Form S-4 or Form S-8 or any
successor forms thereto, or (ii) filed solely in connection with a dividend
reinvestment plan or employee benefit plan covering officers or directors of the
Company or its Affiliates) or for the account of any holder of securities of the
same type as the Registrable Shares or the securities into which the Registrable
Securities then are convertible (to the extent that the Company has the right to
include Registrable Shares in any registration statement to be filed by the
Company on behalf of such holder), then the Company shall give written notice of
such proposed filing to the Holders at least fifteen (15) days before the
anticipated filing date. Such notice shall offer the Holders the opportunity to
register such amount of Registrable Shares as they may request (a "Piggyback
Registration"). Subject to Section 3(b), the Company shall include in each such
Piggyback Registration all Registrable Shares with respect to which the Company
has received written requests for inclusion therein within ten (10) days after
notice has been given to the Holders. Each Holder shall be permitted to withdraw
all or any portion of the Registrable Shares of such Holder from a Piggyback
Registration at any time prior to the effective date of such Piggyback
Registration.

     (b) Priority on Piggyback Registrations. The Company shall permit the
Holders to include all such Registrable Shares on the same terms and conditions
as any similar securities, if any, of the Company included therein.
Notwithstanding the foregoing, if the managing underwriter or underwriters
participating in such offering advise the Holders in writing that the total
amount of securities requested to be included in such Piggyback Registration
exceeds the amount which can be sold in (or during the time of) such offering
without delaying or jeopardizing the success of the offering (including the
price per share of the securities to be sold), then the amount of securities to
be offered for the account of the Holders and other holders of securities who
have piggyback registration rights with respect thereto shall be reduced (to
zero if necessary) (i) first, by reducing pro-rata the securities included
therein held by each of the holders participating in such offering, and (ii)
second, by reducing the securities included therein held by the Holders
participating in such offering.

     (c) Right To Abandon. Nothing in this Section 3 shall create any liability
on the part of the Company to the Holders if the Company in its sole discretion
should decide not to file a registration statement proposed to be filed pursuant
to Section 3(a) or to withdraw such registration statement subsequent to its
filing, regardless of any action whatsoever that a Holder may have taken,
whether as a result of the issuance by the Company of any notice hereunder or
otherwise.

     SECTION 4. Holdback Agreement. If (i) during the Effectiveness Period, the
Company shall file a registration statement (other than in connection with the
registration of securities issuable pursuant to an employee stock option, stock
purchase or similar plan or pursuant to a merger, exchange offer or a
transaction of the type specified in Rule 145(a) under the Securities Act) with
respect to the Common Stock or similar securities or securities convertible
into, or exchangeable or exercisable for, such securities and (ii) with
reasonable prior notice, the Company (in the case of a non-underwritten public
offering by the Company pursuant to such registration statement) advises the
Holders in writing that a public sale or distribution of such Registrable Shares
would materially adversely affect such offering or the managing underwriter or
underwriters (in the case of an underwritten public offering by the Company
pursuant to such registration statement) advises the Company in writing (in
which case the Company shall notify the Holders) that a

                                        4
<PAGE>   31

public sale or distribution of Registrable Shares would materially adversely
impact such offering, then each Holder shall, to the extent not inconsistent
with applicable law, refrain from, and agree in a writing to the Company and the
underwriter or underwriters to refrain from, effecting any public sale or
distribution of Registrable Shares during the ten (10) days prior to the
effective date of such registration statement and until the earliest of (A) the
abandonment of such offering, (B) ninety (90) days from the effective date of
such registration statement and (C) if such offering is an underwritten
offering, the termination in whole or in part of any "hold back" period obtained
by the underwriter or underwriters in such offering from the Company in
connection therewith (each such period, a "Holdback Period").

     SECTION 5. Eligibility for Form S-3. The Company represents and warrants
that it meets the requirements for the use of Form S-3 for registration of the
resale by Holder of the Registrable Shares. The Company covenants and agrees
that for so long as Registrable Shares remain outstanding, the Company shall
continue to be eligible to use Form S-3 for registration of such resale and the
Company shall file all reports required to be filed by the Company with the SEC
in a timely manner so as to maintain such eligibility for the use of Form S-3.

     SECTION 6. Registration Procedures. In connection with the registration
obligations of the Company pursuant to and in accordance with Sections 2 and 3
(and subject to Sections 2 and 3), the Company shall use commercially reasonable
efforts to effect such registration to permit the sale of such Registrable
Shares in accordance with the intended method or methods of disposition thereof,
and pursuant thereto the Company shall as expeditiously as possible (but subject
to Sections 2 and 3):

     (a) prepare and file with the SEC a Registration Statement for the sale of
the Registrable Shares on any form for which the Company then qualifies or which
counsel for the Company shall deem appropriate in accordance with such Holders'
intended method or methods of distribution thereof, subject to the last proviso
of the first sentence of Section 2(a), Section 2(b), and, subject to the
Company's right to terminate or abandon a registration pursuant to Section
3(c),use commercially reasonable efforts to cause such Registration Statement to
become effective and remain effective as provided herein; provided, however,
that the Company shall permit the Holders and their counsel to review the
Registration Statement within a reasonable period of time prior to filing the
Registration Statement with the SEC and not file the Registration Statement in a
form to which such counsel reasonably objects;

     (b) prepare and file with the SEC such amendments (including post-effective
amendments) to such Registration Statement, and such supplements to the related
Prospectus, as may be required by the rules, regulations or instructions
applicable to the Securities Act during the applicable period in accordance with
the intended methods of disposition specified by the Holders of the Registrable
Shares covered by such Registration Statement, make generally available earnings
statements satisfying the provisions of Section 11(a) of the Securities Act
(provided that the Company shall be deemed to have complied with this clause if
it has complied with Rule 158 under the Securities Act), and cause the related
Prospectus as so supplemented to be filed pursuant to Rule 424 under the
Securities Act; provided, however, that before filing any amendments or
supplements to the Registration Statement, the Company shall permit the Holders
of Registrable Shares covered by such Registration Statement and their counsel
to review such amendment or supplement within a reasonable period of time prior
to filing such amendment or supplement with the SEC and not file such amendment
or supplement in a form to which such counsel reasonably objects;

     (c) notify the Holders of any Registrable Shares covered by such
Registration Statement promptly and (if requested) confirm such notice in
writing, (i) when a Prospectus or any Prospectus supplement or post-effective
amendment has been filed, and, with respect to such Registration Statement or
any post-effective amendment, when the same has become effective; provided,
however, that the Company will not request acceleration without prior notice to
the Holders' counsel, (ii) of any request by the SEC for amendments or
supplements to such Registration Statement or the related Prospectus or for
additional information regarding such Holders, (iii) of the issuance by the SEC
of any stop order suspending the effectiveness of such Registration Statement or
the initiation of any proceedings for that purpose, (iv) of the receipt by the
Company of any notification with respect to the suspension of the qualification
or exemption from qualification of any of the Registrable Shares for sale in any
jurisdiction or the initiation or threatening of any proceeding

                                        5
<PAGE>   32

for such purpose, and (v) of the happening of any event that requires the making
of any changes in such Registration Statement, Prospectus or documents
incorporated or deemed to be incorporated therein by reference so that they will
not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading;

     (d) use commercially reasonable efforts to obtain the withdrawal of any
order suspending the effectiveness of such Registration Statement, or the
lifting of any suspension of the qualification or exemption from qualification
of any Registrable Shares for sale in any jurisdiction in the United States;

     (e) furnish to the Holders of any Registrable Shares covered by such
Registration Statement, each counsel for such Holders and each managing
underwriter, if any, without charge, one conformed copy of such Registration
Statement, as declared effective by the SEC, and of each post-effective
amendment thereto, in each case including financial statements and schedules and
all exhibits and reports incorporated or deemed to be incorporated therein by
reference; and deliver, without charge, such number of copies of the preliminary
prospectus, any amended preliminary prospectus, each final Prospectus and any
post-effective amendment or supplement thereto, as such Holder may reasonably
request in order to facilitate the disposition of the Registrable Shares of such
Holder covered by such Registration Statement in conformity with the
requirements of the Securities Act;

     (f) prior to any public offering of Registrable Shares covered by such
Registration Statement, use commercially reasonable efforts to register or
qualify such Registrable Shares for offer and sale under the securities or Blue
Sky laws of such jurisdictions as the Holders of such Registrable Shares shall
reasonably request in writing; provided, however, that the Company shall in no
event be required to qualify generally to do business as a foreign corporation
or as a dealer in any jurisdiction where it is not at the time so qualified or
to execute or file a general consent to service of process in any such
jurisdiction where it has not theretofore done so or to take any action that
would subject it to general service of process or taxation in any such
jurisdiction where it is not then subject;

     (g) upon the occurrence of any event contemplated by paragraph 6(c) (v),
prepare a supplement or post-effective amendment to such Registration Statement
or the related Prospectus or any document incorporated or deemed to be
incorporated therein by reference and file any other required document so that,
as thereafter delivered to the purchasers of the Registrable Shares being sold
thereunder, such Prospectus will not contain an untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading;

     (h) use commercially reasonable efforts to cause all Registrable Shares
covered by such Registration Statement to be listed on each securities exchange
or automated interdealer quotation system, if any, on which similar securities
issued by the Company are then listed or quoted;

     (i) on or before the effective date of such Registration Statement, provide
the transfer agent of the Company for the Registrable Shares with printed
certificates for the Registrable Shares covered by such Registration Statement,
which are in a form eligible for deposit with The Depository Trust Company;

     (j) if such offering is an underwritten offering, make available for
inspection by any Holder of Registrable Shares included in such Registration
Statement, any underwriter participating in any offering pursuant to such
Registration Statement, and any attorney, accountant or other agent retained by
any such Holder or underwriter (collectively, the "Inspectors"), all financial
and other records and other information, pertinent corporate documents and
properties of any of the Company and its subsidiaries and affiliates
(collectively, the "Records"), as shall be reasonably necessary to enable them
to exercise their due diligence responsibilities; provided, however, that the
Records that the Company determines, in good faith, to be confidential and which
it notifies the Inspectors in writing are confidential shall not be disclosed to
any Inspector unless such Inspector signs a confidentiality agreement reasonably
satisfactory to the Company (which shall permit the disclosure of such Records
in such Registration Statement or the related Prospectus if necessary to avoid
or correct a material misstatement in or material omission from such
Registration Statement or Prospectus) or either (i) the disclosure of such
Records is necessary to avoid or correct a

                                        6
<PAGE>   33

misstatement or omission in such Registration Statement or (ii) the release of
such Records is ordered pursuant to a subpoena or other order from a court of
competent jurisdiction; provided, further, however, that (A) any decision
regarding the disclosure of information pursuant to subclause (i) shall be made
only after consultation with counsel for the applicable Inspectors and the
Company and (B) with respect to any release of Records pursuant to subclause
(ii), each Holder of Registrable Shares agrees that it shall, promptly after
learning that disclosure of such Records is sought in a court having
jurisdiction, give notice to the Company so that the Company, at the Company's
expense, may undertake appropriate action to prevent disclosure of such Records;
and

     (k) if such offering is an underwritten offering, enter into such
agreements (including an underwriting agreement in form, scope and substance as
is customary in underwritten offerings) and take all such other appropriate and
reasonable actions requested by the Holders of a majority of the Registrable
Shares being sold in connection therewith (including those reasonably requested
by the managing underwriters) in order to expedite or facilitate the disposition
of such Registrable Shares, and in such connection, (i) use commercially
reasonable efforts to obtain opinions of counsel to the Company and updates
thereof (which counsel and opinions (in form, scope and substance) shall be
reasonably satisfactory to the managing underwriters and counsel to the Holders
of the Registrable Shares being sold), addressed to each selling Holder of
Registrable Shares covered by such Registration Statement and each of the
underwriters as to the matters customarily covered in opinions requested in
underwritten offerings and such other matters as may be reasonably requested by
such counsel and underwriters, (ii use commercially reasonable efforts to obtain
"cold comfort" letters and updates thereof from the independent certified public
accountants of the Company (and, if necessary, any other independent certified
public accountants of any subsidiary of the Company or of any business acquired
by the Company for which financial statements and financial data are, or are
required to be, included in the Registration Statement), addressed to each
selling holder of Registrable Shares covered by the Registration Statement
(unless such accountants shall be prohibited from so addressing such letters by
applicable standards of the accounting profession) and each of the underwriters,
such letters to be in customary form and covering matters of the type
customarily covered in "cold comfort" letters in connection with underwritten
offerings, (iii) if requested and if an underwriting agreement is entered into,
provide indemnification provisions and procedures substantially to the effect
set forth in Section 9 hereof with respect to all parties to be indemnified
pursuant to such Section. The above shall be done at each closing under such
underwriting or similar agreement, or as and to the extent required thereunder.

     The Company may require each Holder of Registrable Shares covered by a
Registration Statement to furnish such information regarding such Holder and
such Holder's intended method of disposition of such Registrable Shares as it
may from time to time reasonably request in writing. If any such information is
not furnished within a reasonable period of time after receipt of such request,
the Company may exclude such Holder's Registrable Shares from such Registration
Statement, provided, however, the Company shall hold in confidence and not make
any disclosure of information concerning the Holder provided to the Company
unless (a) disclosure of such information is necessary to comply with federal or
state securities laws, (b) the disclosure of such information is necessary to
avoid or correct a misstatement or omission in any Registration Statement, (c)
the release of such information is ordered pursuant to a subpoena or other order
from a court or governmental body of competent jurisdiction or is otherwise
required by applicable law or legal process, (d) such information has been made
generally available to the public other than by disclosure in violation of this
or any other agreement (to the knowledge of the Company), or (e) the Holder
consents to the form and content of any such disclosure. The Company agrees that
it shall, upon learning that disclosure of such information concerning the
Holder is sought in or by a court or governmental body of competent jurisdiction
or through other means, give prompt notice to the Holder prior to making such
disclosure, and allow the Holder, at its expense, to undertake appropriate
action to prevent disclosure of, or to obtain a protective order for, such
information.

     Each Holder of Registrable Shares covered by a Registration Statement
agrees that, upon receipt of any notice from the Company of the happening of any
event of the kind described in Section 6(c)(ii), 6(c)(iii), 6(c)(iv) or 6(c)(v),
that such Holder shall forthwith discontinue disposition of any Registrable
Shares covered by such Registration Statement or the related Prospectus until
receipt of the copies of the

                                        7
<PAGE>   34

supplemented or amended Prospectus contemplated by Section 6(g), or until such
Holder is advised in writing (the "Advice") by the Company that the use of the
applicable Prospectus may be resumed, and has received copies of any amended or
supplemented Prospectus or any additional or supplemental filings which are
incorporated, or deemed to be incorporated, by reference in such Prospectus
(such period during which disposition is discontinued being an "Interruption
Period") and, if requested by the Company, the Holder shall deliver to the
Company (at the expense of the Company) all copies then in its possession, other
than permanent file copies then in such holder's possession, of the Prospectus
covering such Registrable Shares at the time of receipt of such request.

     Each Holder of Registrable Shares covered by a Registration Statement
further agrees not to utilize any material other than the applicable current
preliminary prospectus or Prospectus in connection with the offering of such
Registrable Shares.

     SECTION 7. Registration Expenses. Whether or not any Registration Statement
is filed or becomes effective, the Company shall pay all costs, fees and
expenses incident to the Company's performance of or compliance with this
Agreement, including (i) all registration and filing fees, including NASD filing
fees, (ii) all fees and expenses of compliance with securities or Blue Sky laws,
including reasonable fees and disbursements of counsel in connection therewith,
(iii) printing expenses (including expenses of printing certificates for
Registrable Shares and of printing prospectuses if the printing of prospectuses
is requested by the Holders or the managing underwriter, if any), (iv)
messenger, telephone and delivery expenses, (v) fees and disbursements of
counsel for the Company, (vi) fees and disbursements of all independent
certified public accountants of the Company (including expenses of any "cold
comfort" letters required in connection with this Agreement) and all other
persons retained by the Company in connection with such Registration Statement,
(vii) fees and disbursements of one counsel, other than the Company's counsel,
selected by Holders of a majority of the Registrable Shares being registered, to
represent all such Holders, (viii) fees and disbursements of underwriters
customarily paid by the issuers or sellers of securities and (ix) all other
costs, fees and expenses incident to the Company's performance or compliance
with this Agreement. Notwithstanding the foregoing, the fees and expenses of any
persons retained by any Holder, other than one counsel for all such Holders, and
any discounts, commissions or brokers' fees or fees of similar securities
industry professionals and any transfer taxes relating to the disposition of the
Registrable Shares by a Holder, will be payable by such Holder and the Company
will have no obligation to pay any such amounts.

     SECTION 8. Underwriting Requirements.

     (a) Subject to Section 8(b), any Holder shall have the right, by written
notice, to request that any Demand Registration provide for an Underwritten
Offering.

     (b) In the case of any Underwritten Offering pursuant to a Demand
Registration, the Holders of a majority of the Registrable Shares to be disposed
of in connection therewith shall select the institution or institutions that
shall manage or lead such offering, which institution or institutions shall be
reasonably satisfactory to the Company. In the case of any Underwritten Offering
pursuant to a Piggyback Registration, the Company shall select the institution
or institutions that shall manage or lead such offering. No Holder shall be
entitled to participate in an Underwritten Offering unless and until such Holder
has entered into an underwriting or other agreement (including a "holdback
agreement" to the effect set forth in Section 4) with such institution or
institutions for such offering in such form as the Company and such institution
or institutions shall determine.

     SECTION 9. Indemnification.

     (a) Indemnification by the Company. The Company shall, without limitation
as to time, indemnify and hold harmless, to the full extent permitted by law,
each Holder of Registrable Shares whose Registrable Shares are covered by a
Registration Statement or Prospectus, the officers, directors and agents and
employees of each of them, each Person who controls each such Holder (within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act)
and the officers, directors, agents and employees of each such controlling
person, to the fullest extent lawful, from and against any and all losses,
claims, damages, liabilities, judgment, costs (including, without limitation,
costs of preparation and reasonable attorneys' fees)

                                        8
<PAGE>   35

and expenses (collectively, "Losses"), as incurred, arising out of or based upon
(i) any violation or alleged violation by the Company of the Securities Act, the
Exchange Act, or any other law, including, without limitation, any state
securities law, or any rule or regulation thereunder relating to the offer or
sale of securities, or (ii) any untrue or alleged untrue statement of a material
fact contained in a Registration Statement or Prospectus or in any amendment or
supplement thereto or in any preliminary prospectus, or arising out of or based
upon any omission or alleged omission of a material fact required to be stated
therein or necessary to make the statements therein not misleading, except
insofar as the same are based upon information furnished in writing to the
Company by or on behalf of such Holder expressly for use therein; provided,
however, that the Company shall not be liable to any such Holder to the extent
that any such Losses arise out of or are based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in any preliminary
prospectus if (A) having previously been furnished by or on behalf of the
Company with copies of the Prospectus, such Holder failed to send or deliver a
copy of the Prospectus with or prior to the delivery of written confirmation of
the sale of Registrable Shares by such Holder to the person asserting the claim
from which such Losses arise and (B) the Prospectus would have corrected in all
material respects such untrue statement or alleged untrue statement or such
omission or alleged omission; and provided, further, however, that the Company
shall not be liable in any such case to the extent that any such Losses arise
out of or are based upon an untrue statement or alleged untrue statement or
omission or alleged omission in the Prospectus, if (x) such untrue statement or
alleged untrue statement, omission or alleged omission is corrected in all
material respects in an amendment or supplement to the Prospectus and (y) having
previously been furnished by or on behalf of the Company with copies of the
Prospectus as so amended or supplemented, such Holder thereafter fails to
deliver such Prospectus as so amended or supplemented, prior to or concurrently
with the sale of Registrable Shares.

     (b) Indemnification by Holder of Registrable Shares. In connection with any
Registration Statement in which a Holder is participating, such Holder shall
furnish to the Company in writing such information as the Company reasonably
requests for use in connection with such Registration Statement or the related
Prospectus and agrees to indemnify, to the full extent permitted by law, the
Company, its directors, officers, agents or employees, each Person who controls
the Company (within the meaning of Section 15 of the Securities Act and Section
20 of the Exchange Act) and the directors, officers, agents or employees of such
controlling Persons, from and against all Losses arising out of or based upon
any untrue or alleged untrue statement of a material fact contained in such
Registration Statement or the related Prospectus or any amendment or supplement
thereto, or any preliminary prospectus, or arising out of or based upon any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, to the extent, but only
to the extent, that such untrue or alleged untrue statement or omission or
alleged omission is based upon any information so furnished in writing by or on
behalf of such Holder to the Company expressly for use in such Registration
Statement or Prospectus, provided, however, that the indemnification obligations
of the Holder pursuant to this Section 9(b) shall be limited to a maximum amount
equal to the cash proceeds actually received by the Holder pursuant to any
public offering of securities in connection with such Registration Statement.

     (c) Conduct of Indemnification Proceedings. If any Person shall be entitled
to indemnity hereunder (an "Indemnified Party"), such Indemnified Party shall
give prompt notice to the party from which such indemnity is sought (the
"Indemnifying Party") of any claim or of the commencement of any proceeding with
respect to which such Indemnified Party seeks indemnification or contribution
pursuant hereto; provided, however, that the delay or failure to so notify the
Indemnifying Party shall not relieve the Indemnifying Party from any obligation
or liability except to the extent that the Indemnifying Party has been
prejudiced by such delay or failure. The Indemnifying Party shall have the
right, exercisable by giving written notice to an Indemnified Party promptly
after the receipt of written notice from such Indemnified Party of such claim or
proceeding, to assume, at the Indemnifying Party's expense, the defense of any
such claim or proceeding, with counsel reasonably satisfactory to such
Indemnified Party; provided, however, that (i) an Indemnified Party shall have
the right to employ separate counsel in any such claim or proceeding and to
participate in the defense thereof, but the fees and expenses of such counsel
shall be at the expense of such Indemnified Party unless: (1) the Indemnifying
Party agrees to pay such fees and expenses; (2) the Indemnifying Party fails
promptly to assume the defense of such claim or proceeding or fails to employ
counsel reasonably satisfactory
                                        9
<PAGE>   36

to such Indemnified Party; or (3) the named parties to any proceeding (including
impleaded parties) include both such Indemnified Party and the Indemnifying
Party, and such Indemnified Party shall have been advised by counsel that there
may be one or more legal defenses available to it that are inconsistent with
those available to the Indemnifying Party or that a conflict of interest is
likely to exist among such Indemnified Party and any other indemnified parties
(in which case the Indemnifying Party shall not have the right to assume the
defense of such action on behalf of such Indemnified Party); and (ii) subject to
clause (3) above, the Indemnifying Party shall not, in connection with any one
such claim or proceeding or separate but substantially similar or related claims
or proceedings in the same jurisdiction, arising out of the same general
allegations or circumstances, be liable for the fees and expenses of more than
one firm of attorneys (together with appropriate local counsel) at any time for
all of the indemnified parties. Whether or not such defense is assumed by the
Indemnifying Party, such Indemnified Party shall not be subject to any liability
for any settlement made without its consent. The Indemnifying Party shall not
consent to entry of any judgment or enter into any settlement that does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party of a release, in form and substance reasonably
satisfactory to the Indemnified Party, from all liability in respect of such
claim or litigation for which such Indemnified Party would be entitled to
indemnification hereunder.

     (d) Contribution. If the indemnification provided for in this Section 9 is
unavailable to an Indemnified Party in respect of any Losses (other than in
accordance with its terms), then each applicable Indemnifying Party, in lieu of
indemnifying such Indemnified Party, shall contribute to the amount paid or
payable by such Indemnified Party as a result of such Losses, in such proportion
as is appropriate to reflect the relative fault of the Indemnifying Party, on
the one hand, and such Indemnified Party, on the other hand, in connection with
the actions, statements or omissions that resulted in such Losses as well as any
other relevant equitable considerations. The relative fault of such Indemnifying
Party, on the one hand, and Indemnified Party, on the other hand, shall be
determined by reference to, among other things, whether any action in question,
including any untrue statement of a material fact or omission or alleged
omission to state a material fact, has been taken by, or relates to information
supplied by, such Indemnifying Party or Indemnified Party, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent any such action, statement or omission. The amount paid or payable by a
party as a result of any Losses shall be deemed to include any legal or other
fees or expenses incurred by such party in connection with any investigation or
proceeding. The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 9(d) were determined by pro rata
allocation or by any other method of allocation that does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 9(d), an Indemnifying Party that
is a Holder shall not be required to contribute any amount which is in excess of
the amount by which the total proceeds received by such Holder from the sale of
the Registrable Shares sold by such Holder (net of all underwriting discounts
and commissions) exceeds the amount of any damages that such Indemnifying Party
has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any Person who was not guilty of such
fraudulent misrepresentation.

     SECTION 10. Reports Under the Exchange Act. With a view to making available
to the Holders the benefits of Rule 144 promulgated under the Securities Act or
any other similar rule or regulation of the SEC that may at any time permit the
Holders to sell securities of the Company to the public without registration
("Rule 144"), the Company agrees, until termination of this Agreement pursuant
to Section 12(a), to:

     (a) Make and keep "public information" available, as those terms are
understood and defined in Rule 144;

     (b) File with the SEC in a timely manner and make and keep available all
reports and other documents required of the Company under the Securities Act and
the Exchange Act so long as the Company remains subject to such requirements and
the filing and availability of such reports and other documents is required for
the applicable provisions of Rule 144; and

                                       10
<PAGE>   37

     (c) Furnish to the Holders so long as the Holders hold Registrable Shares,
promptly upon request, (i) a written statement by the Company that it has
complied with the reporting requirements of Rule 144, the Securities Act and the
Exchange Act, (ii) a copy of the most recent annual or quarterly report of the
company and such other reports and documents so filed by the Company, and (iii)
such other information as may be reasonably requested to permit the Holders to
sell such securities pursuant to Rule 144 without registration.

     SECTION 11. Transfer of Registration Rights. The rights to cause the
Company to register Registrable Shares pursuant to this Agreement may not be
assigned by a Holder to a transferee or assignee of such securities except to a
Person who has agreed to be bound by the terms of this Agreement as if such
Person were a Holder.

     SECTION 12. Miscellaneous.

     (a) Termination. This Agreement and the obligations of the Company and the
Holders hereunder (other than Section 9) shall terminate on the first date on
which no Registrable Shares remain outstanding.

     (b) No Inconsistent Agreements. The Company shall not on or after the date
of this Agreement enter into any agreement with respect to its securities which
is inconsistent with or limits or impairs the rights granted to the Holder in
this Agreement or otherwise conflicts with the provisions hereof.

     (c) Adjustments Affecting Registrable Shares. The Company shall not take
any action, or permit any change to occur, with respect to the Registrable
Shares which would adversely affect the ability of the Holders of Registrable
Shares to include such Registrable Shares in a registration undertaken pursuant
to this Agreement.

     (d) Notices. All notices or communications hereunder shall be in writing

                          ADVISORY SERVICES AGREEMENT

     THIS ADVISORY SERVICES AGREEMENT is entered into as of September [  ], 1999
(the "Agreement"), by and between Churchill Capital, Inc., a Minnesota
corporation (the "Advisor"), and Asche Transportation Services, Inc., a Delaware
corporation (the "Company").

                                  WITNESSETH:

     WHEREAS, the Company has entered into a Stock Purchase Agreement (the
"Purchase Agreement") dated as of August   , 1999, with an affiliate of Advisor,
Churchill Environmental & Industrial Equity Partners, L.P. (the "Purchaser"), a
limited partnership organized under the laws of the State of Delaware;

     WHEREAS, the Company and the Advisor have agreed that the Advisor make
available to the Company certain management and financial advisory services
commencing on the date hereof;

     WHEREAS, the Advisor desires to provide such management and financial
advisory services to the Company commencing on the date hereof; and

     WHEREAS, capitalized terms used but not defined herein have meanings as set
forth in the Purchase Agreement.

     NOW THEREFORE, in consideration of the mutual covenants and agreements
contained herein, it is agreed as follows:

     1. Engagement and Duties

     1.1 The Company hereby appoints the Advisor as an advisor to the Company,
whereby the Advisor shall, from time to time, provide those management and
financial advisory services to the Company and the Subsidiaries which are set
forth in Section 1.2 hereof. The Advisor hereby accepts such appointment and
agrees to provide each of the services required to be provided by it under this
Agreement and to make itself available from time-to-time, on a part-time basis,
to consult with the management and the Board of Directors of the Company (the
"Board") in connection with such services.

     1.2 Upon the reasonable request of the Board, the Advisor hereby agrees to
provide the following services to the Company and its Subsidiaries, if any:

          (a) review periodically the business, operations, financial condition
     and prospects of the Company and its Subsidiaries, including, without
     limitation: (i) reviewing the strategic direction and plans of the Company
     and its Subsidiaries; (ii) reviewing and evaluating the annual business
     plan and budget of the Company and its Subsidiaries; and (iii) reviewing
     and evaluating the sales, profitability and working capital and other
     financing requirements of the Company and its Subsidiaries;

          (b) assist the Company and its Subsidiaries in seeking out and
     negotiating with potential financing sources in connection with financing
     transactions of the Company;

          (c) provide to the Company and its Subsidiaries such other management
     and financial advisory services as may be reasonably requested by the
     Board; and

          (d) assist the Company and its Subsidiaries regarding any claims for
     indemnification on behalf of the Company or its Subsidiaries pursuant to
     the Purchase Agreement.

     2. Nature of Relationship. Notwithstanding the services provided by the
Advisor, the Advisor shall be deemed to be an independent contractor and, unless
otherwise expressly authorized by the Company's Board, shall not be authorized
to manage the affairs of, act in the name of or bind the Company. The Company
shall not be obligated to follow or accept any advice or recommendation made by
the Advisor, and the management, policies and operations of the Company shall be
the sole responsibility of the Board and the management of the Company. The
obligations of the Advisor to the Company are not exclusive, and the Advisor
may, in its sole discretion, render the same or similar services to any other
person or entity. Nothing
<PAGE>   41

set forth in this Agreement shall be deemed to prohibit the Advisor from serving
any other person or entity in any capacity the Advisor may deem appropriate or
from conducting its business and affairs in any manner it may elect, whether or
not such activities might involve an actual or potential conflict of interest
with respect to the Company or any of its Subsidiaries. In the event Advisor
engages in activities which are competitive with the business of the Company,
the Advisor agrees not to disclose any Company proprietary information to such
competitive enterprise.

     3. Term. Subject to the termination provisions of Section 7 hereof, the
term of the Advisor's engagement hereunder (the "Term") shall commence on the
date hereof and continue until the earlier of (i) the time when Purchaser and
its successors and assigns no longer beneficially own in the aggregate more then
fifty percent (50%) of the number of Initial Shares and Additional Shares
originally issued to Purchaser and (ii) the fifth anniversary hereof.

     4. Compensation and Expenses.

     4.1 In consideration of the services to be provided by the Advisor to the
Company, during the Term the Company shall pay the Advisor a monthly management
fee of $10,000 (the "Management Fee"), payable at the Closing (as defined in the
Purchase Agreement) and each monthly anniversary of the Closing thereafter.

     4.2 On the date hereof, the Company shall pay to the Advisor an investment
banking fee of $360,000 by wire transfer of immediately available funds.

     4.3 Upon execution of this Agreement, Company shall pay Advisor a one time
administrative fee of $5,000.00 by wire transfer of immediately available funds.

     4.4 The Company shall also pay or reimburse the Advisor for all Expenses
incurred by the Advisor during the Term (as defined in Section 4.6).

     4.5 Upon any termination of the Advisor's engagement hereunder, the
Management Fee payable with respect to the then current month shall be prorated
to reflect the actual number of days during which the Advisor was engaged by the
Company.

     4.6 The term "Expenses" shall mean all fees, costs and expenses reasonably
incurred by the Advisor in connection with its provision of services hereunder,
including, without limitation: (i) all reasonable fees and expenses of legal
counsel, accountants and other consultants and experts retained by the Advisor
in connection with its provision of services hereunder, (ii) all travel and
other out-of-pocket costs and expenses incurred by the Advisor in connection
therewith, and (iii) all Losses (as defined below) that are the subject of
indemnification pursuant to this Agreement. The Company shall reimburse the
Advisor promptly for all Expenses upon the Advisor's presentation of invoices or
other documents reasonably evidencing such Expenses.

     5. Indemnification.

     5.1 The Company shall, to the fullest extent permitted by law, indemnify
the Advisor and its Affiliates and their respective directors, officers,
stockholders, employees and agents (collectively, the "Indemnitees") against,
and the Company will hold harmless and will release each Indemnitee from, any
and all Losses (as defined below), including any incurred in connection with any
action, claim, suit, inquiry, proceeding, investigation or appeal taken from the
foregoing by or before any court or governmental, administrative or other
regulatory agency, body or commission, whether pending or threatened, whether or
not any Indemnitee is or may be a party thereto, which arise out of, relate to
or are in connection with the provision of any services hereunder or otherwise
relate to this Agreement or the management or conduct of the business or affairs
of the Company or any of its Subsidiaries. The Company shall not be required to
indemnify any Indemnitee for Losses that are determined by a court of competent
jurisdiction pursuant to a final, nonappealable order to have resulted primarily
from the gross negligence or willful misconduct of the Indemnitee seeking
indemnification. The term "Losses" shall mean all losses, claims, damages or
liabilities of each Indemnitee, joint or several, and all judgments, fines,
penalties, interest and charges, and all costs and expenses incurred in
connection with the investigation, defense or settlement of any pending or
threatened claims (including, without limitation, attorneys' fees and expenses
related thereto).

                                        2
<PAGE>   42

     5.2 The termination of any proceeding by settlement shall not, of itself,
create a presumption that the Indemnitee acted in a manner which constituted
gross negligence or willful misconduct. The right of any Indemnitee to the
indemnification provided herein shall be cumulative of, and in addition to, any
and all rights to which such Indemnitee may otherwise be entitled by contract or
as matter of law or equity and shall extend to his heirs, successors, assigns
and legal representatives.

     5.3 Promptly after receipt by an Indemnitee hereunder of written notice of
the commencement of any action or proceeding with respect to which a claim for
indemnification may be made pursuant to this Section 5, such Indemnitee will, if
a claim in respect thereof is to be made against the Company promptly give
written notice to the Company of the commencement of such action; provided that
the failure of any Indemnitee to give notice as provided herein shall not
relieve the Company of its obligations under this Section 5, except to the
extent that the Company is actually and materially prejudiced by such failure to
give notice. In case any such action is brought against an Indemnitee, Company
will be entitled to participate in and to assume the defense thereof, to the
extent that it may wish, with counsel reasonably satisfactory to such
Indemnitee, and after notice from the Company of its election to assume the
defense thereof, the Company will not be liable to such Indemnitee for any legal
or other expenses subsequently incurred by the Indemnitee in connection with the
defense thereof, unless in such Indemnitee's reasonable judgment a conflict of
interest between the Indemnitee and the Company arises in respect of such claim
after the assumption of the defense thereof (in which case, the Company shall
not assume the defense thereof, but shall be responsible for the fees and
expenses of one counsel in each jurisdiction for all parties indemnified by the
Company, subject to the same exception as is set forth in the last sentence of
this subsection 5.3), and the Company will not be subject to any liability for
any settlement made without its consent (which consent shall not be unreasonably
withheld). The Company will not consent to entry of any judgment or enter into
any settlement (a) which does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such Indemnitee of a release from all
liability in respect to such claim or litigation, and (b) that imposes any
obligation on an Indemnitee (except any obligation to make payments which the
Company shall, and promptly does, pay). If the Company elects not to assume the
defense of a claim, it will not be obligated to pay the fees and expenses of
more than one counsel for all parties indemnified by the Company with respect to
such claim, unless in the reasonable judgment of any Indemnitee a conflict of
interest may exist between such Indemnitee and any other of such Indemnitees
with respect to such claim, in which event the Company shall be obligated to pay
the fees and expenses of such additional counsel or counsels.

     5.4 Notwithstanding any termination of the Advisor's engagement hereunder
pursuant to Section 7, the expiration of the Term pursuant to Section 3 or
otherwise, the indemnification and contribution provided under this Agreement
shall remain in full force and effect thereafter.

     5.5 No Indemnitee shall be liable to the Company or its Subsidiaries for
any error of judgment or mistake of law or for any loss incurred by the Company
or its Subsidiaries or any of their respective Affiliates in connection with the
matters to which this Agreement relates, except for any damages that are
determined by a court of competent jurisdiction pursuant to a final,
nonappealable order to have resulted primarily from the gross negligence or
willful misconduct of the Indemnitee seeking indemnification. In no event shall
the Advisor or any Indemnitee be liable for (i) any indirect, special or
consequential damages arising out of or in connection with this Agreement and
(ii) damages in excess of the total fees (and expressly excluding Expenses)
actually received by the Advisor pursuant to Section 4 of this Agreement. The
Advisor and the Indemnitees may consult with legal counsel, accountants and
other consultants and experts in respect of the affairs of the Company and its
Subsidiaries and shall be fully protected and justified in acting, or failing to
act, in a manner consistent with the advice or opinion of such legal counsel,
accountants and other consultants and experts.

     6. Contribution. If the indemnification provided for in Section 5.1 is
judicially determined by a court of competent jurisdiction pursuant to a final,
nonappealable order to be unavailable (other than in accordance with the second
sentence of Section 5.1) to an Indemnitee in respect of any Losses, then, in
lieu of indemnifying such Indemnitee hereunder, the Company shall contribute to
the amount paid or payable by such Indemnitee as a result of such Losses (i) in
such proportion as is appropriate to reflect the relative benefits to the
Advisor and its Affiliates, on the one hand, and the Company, on the other hand,
in connection
                                        3
<PAGE>   43

with the services heretofore provided to the Company by the Advisor or the
services provided by the Advisor under this Agreement, as the case may be, or
(ii) if the allocation provided by clause (i) above is not available, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in such clause (i) but also the relative fault of each of the Advisor and its
Affiliates and the Company, as well as any other relevant equitable
considerations; provided, however, that in no event shall the Indemnitee's
aggregate contribution to the amount paid or payable exceed the aggregate amount
of fees (and expressly excluding Expenses) actually received by the Advisor
under Section 4 of this Agreement.

     7. Termination. Notwithstanding anything to the contrary contained in this
Agreement the Advisor's engagement hereunder may be terminated by the Advisor
upon at least forty-five (45) days prior written notice to the Company.

     8. Notices. All notices and other communications under or in connection
with this Agreement shall be in writing and shall be deemed given (a) if
delivered personally, upon delivery, (b) if delivered by registered or certified
mail (return receipt requested), upon the earlier of actual delivery or three
days after being mailed, or (c) if given by telecopy, upon confirmation of

reason of any event or cause whatsoever beyond the reasonable control of the

               (g) Severability. Whenever possible, each provision or portion of
any provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable law but if any provision or portion of any
provision of this Agreement is held to be invalid, illegal or unenforceable in
any respect under any applicable law or rule in any jurisdiction, such

contained herein.

               (h) Specific Performance. Each of the parties hereto recognizes
and acknowledges that a breach by it of any covenant or agreement contained in

not have an adequate remedy at law for money damages, and therefore each of the
parties hereto agrees that in the event of any such breach the aggrieved party
shall be entitled to the remedy of specific performance of such covenants and
agreements and injunctive and other equitable relief in addition to any other
remedy to which it may be entitled, at law or in equity.

               (i) Remedies Cumulative. All rights, powers and remedies provided
under this Agreement or otherwise available in respect hereof at law or in
equity shall be cumulative and not alternative, and the exercise of any thereof
by any party shall not preclude the simultaneous or later exercise of any other
such right, power or remedy by such party.

               (j) No Waiver. The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise any such or other right, power or remedy or to
demand such compliance.

               (k) No Third Party Beneficiaries. This Agreement is not intended
to be for the benefit of, and shall not be enforceable by, any Person who or
which is not a party hereto.

                                VOTING AGREEMENT

This Voting Agreement (this "Agreement"), dated as of August 17, 1999 among
Churchill Environmental & Industrial Equity Partners, L.P. a limited partnership
organized under the laws of the State of Delaware ("Purchaser"), and Larry L.
Asche, a stockholder (the "Stockholder") of Asche Transportation Services, Inc.,
a Delaware corporation (the "Company").

                                   WITNESSETH:

         WHEREAS, concurrently herewith, Purchaser and the Company are entering
into a Stock Purchase Agreement (as such agreement may hereafter be amended from
time to time, the "Stock Purchase Agreement"), pursuant to which the Purchaser
will purchase from the Company shares of Common Stock of the Company, par value
$.0001 per share (the "Common Stock"); and

         WHEREAS, as an inducement and a condition to entering into the Stock
Purchase Agreement, Purchaser has required that the Stockholder agree, and the
Stockholder has agreed, to enter into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual premises,
representations, warranties, covenants and agreements contained herein, the
parties hereto, intending to be legally bound, hereby agree as follows:

1. Definitions. Capitalized terms used and not defined herein have the
respective meanings ascribed to them in the Stock Purchase Agreement. For
purposes of this Agreement:

or understanding, whether or not in writing. Notwithstanding the foregoing,
securities Beneficially Owned by a Person shall not include securities which are
actually owned by other Persons but which such Person may be deemed to
Beneficially Own under Rule 13d-3 under the Exchange Act solely because such
Person may be deemed to be part of a "group" with such other Persons as within
the meaning of Section 13(d)(3) of the Exchange Act.

         (c) "Related Party" or "Related Parties" means Affiliates of the

the Company under the Stock Purchase Agreement or the Related Agreements or of
the Stockholder under this Agreement or that would result in any of the
conditions to the obligations of the Company under the Stock Purchase Agreement
not being fulfilled; and (vi) until the Investment Proposal shall have been duly
approved by the holders of Company Stock, and except as otherwise agreed to in
writing in advance by Purchaser, against each of the following actions (other

Agreement and the Related Agreements): (A) any extraordinary corporate
transaction, such as a merger, consolidation or other business combination
involving the Company or its Subsidiaries; (B) a sale, lease or transfer of a

in the Company Stock by reason of any stock dividend, split-up,
recapitalization, combination, exchange of shares or the like, the term "Shares"
shall be deemed to refer to and include the Shares as well as all such stock
dividends and distributions and any shares into which or for which any or all of
the Shares may be changed or exchanged.

hereby represents, warrants and covenants to Purchaser as follows:

            (c) No Conflicts. (i) No filing with, and no permit, authorization,
consent or approval of, any state or federal public body or authority is
necessary for the execution of this Agreement by the Stockholder and the
consummation by the Stockholder of the transactions contemplated hereby, and
(ii) none of the execution and delivery of this Agreement by the Stockholder,
the consummation by the Stockholder of the transactions contemplated hereby or

time or both) a default (or give rise to any third party right of termination,
cancellation, material modification or acceleration) under any of the terms,
conditions or provisions of any note, bond, mortgage, indenture, license,
contract, commitment, arrangement, understanding, agreement or other instrument
or obligation of any kind to which the Stockholder is a party or by which the

(B) violate any order, writ, injunction, decree, judgment, order, statute, rule
or regulation applicable to the Stockholder or any of the Stockholder's
properties or assets.

            (d) Proxies and Non-Interference. Beginning on the date hereof and
continuing until this Agreement terminates pursuant to Section 4, the

any proposal to acquire, or (y) in any manner Transfer (as hereinafter defined),
directly or indirectly shares of Common Stock of the Company, (ii) make or in
any way participate, directly or indirectly, in any "solicitation" of "proxies"

the voting of, any shares of Common Stock of the Company, or (iii) form, join or
in any way participate in a "group" (within the meaning of Section 13(d) of the
Exchange Act) with respect to any shares of Common Stock of the Company.

            (f) Reliance by Purchaser. The Stockholder understands and
acknowledges that Purchaser is entering into the Stock Purchase Agreement in

         4. Termination. This Agreement shall terminate only upon, and
simultaneously with, the termination of the Stock Purchase Agreement in

         5. Stockholder Capacity. No Person executing this Agreement who is or
becomes during the term hereof a director of the Company makes any agreement or
understanding herein in his or her capacity as such director. The Stockholder

            (b) Restriction on Transfers. Prior to the Stockholder Meeting, this

and shall be binding upon any Person to which legal or Beneficial Ownership of

"Transfer"), or enter into any contract, option or other arrangement with
respect to the Transfer of any of the Stockholder's Shares, unless as a

Section 4, (y) the period ending on the fifth anniversary after the Closing
Date, and (z) the date Purchaser and its successors and assigns no longer
beneficially own in the aggregate more than fifty percent (50%) of the number of

and any purported assignment or delegation in violation hereof shall be null and
void, provided, however, that Purchaser may assign all or any part of its
rights, interests and obligations hereunder to any Affiliate of Purchaser;
provided, that no such assignment before the Closing Date by Purchaser shall
relieve Purchaser of its obligations hereunder.

            (e) Amendments, Waivers, Etc. This Agreement may not be amended,
changed, supplemented, waived or otherwise modified or terminated with respect

acknowledges that a breach by it of any covenant or agreement contained in this

equity shall be cumulative and not alternative, and the exercise of any thereof
by any party shall not preclude the simultaneous or later exercise of any other
such right, power or remedy by such party.

right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise any such or other right, power or remedy or to
demand such compliance.

            (k) No Third Party Beneficiaries. This Agreement is not intended to
be for the benefit of, and shall not be enforceable by, any Person who or which

                                VOTING AGREEMENT

This Voting Agreement (this "Agreement"), dated as of August 17, 1999 among
Churchill Environmental & Industrial Equity Partners, L.P. a limited partnership
organized under the laws of the State of Delaware ("Purchaser"), and Diane L.
Asche, a stockholder (the "Stockholder") of Asche Transportation Services, Inc.,
a Delaware corporation (the "Company").

                                   WITNESSETH:

         WHEREAS, concurrently herewith, Purchaser and the Company are entering
into a Stock Purchase Agreement (as such agreement may hereafter be amended from
time to time, the "Stock Purchase Agreement"), pursuant to which the Purchaser
will purchase from the Company shares of Common Stock of the Company, par value
$.0001 per share (the "Common Stock"); and

         WHEREAS, as an inducement and a condition to entering into the Stock
Purchase Agreement, Purchaser has required that the Stockholder agree, and the
Stockholder has agreed, to enter into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual premises,
representations, warranties, covenants and agreements contained herein, the
parties hereto, intending to be legally bound, hereby agree as follows:

         1. Definitions. Capitalized terms used and not defined herein have the
respective meanings ascribed to them in the Stock Purchase Agreement. For
purposes of this Agreement:

            (a) "Company Stock" shall mean at any time, collectively, shares of
Common Stock.

            (b) "Beneficially Own" or "Beneficial Ownership" with respect to any
securities shall mean having "Beneficial Ownership" of such securities (as
determined pursuant to Rule 13d-3 under the Securities Exchange Act of 1934, as
amended (the "Exchange Act")), including pursuant to any agreement, arrangement
or understanding, whether or not in writing. Notwithstanding the foregoing,
securities Beneficially Owned by a Person shall not include securities which are
actually owned by other Persons but which such Person may be deemed to
Beneficially Own under Rule 13d-3 under the Exchange Act solely because such
Person may be deemed to be part of a "group" with such other Persons as within
the meaning of Section 13(d)(3) of the Exchange Act.

            (c) "Related Party" or "Related Parties" means Affiliates of the
Stockholder and the Company, principal stockholders of the Company, the spouse
of the Stockholder, family members of the Stockholder, and any family trust or
similar instrument (whether the Stockholder is a beneficiary or trustee
thereof).

         2. Provisions Concerning Company Stock.

            (a) The Stockholder hereby agrees that during the period commencing
on the date hereof and continuing for so long as the Stockholder holds any
shares of Common Stock, at any meeting of the holders of Company Stock, however
called, or in connection with any written consent of the holders of Company
Stock, the Stockholder shall vote (or cause to be voted) all shares of Company
Stock held of record or Beneficially Owned by the Stockholder, whether
heretofore owned or hereafter acquired (collectively, the "Shares"): (i) in
favor of the Charter Amendment; (ii) in favor of the Investment Proposal and the
execution and delivery by the Company of the Stock Purchase Agreement and the
Related Agreements, the approval of the terms thereof and each of the other
transactions and actions contemplated thereby (and the matters related to the
consummation thereof); (iii) in favor of the appointment of the Purchaser
Designees to the Board of Directors of the Company, as contemplated by the Stock
Purchase Agreement; (iv) in favor of the Charter and By-Law Amendments; (v)
against any action or agreement that would result in a breach in any respect of
any covenant, representation or warranty or any other obligation or agreement of
the Company under the Stock Purchase Agreement or the Related Agreements or of
the Stockholder under this Agreement or that would result in any of the
conditions to the obligations of the Company under the Stock Purchase Agreement
not being fulfilled; and (vi) until the Investment Proposal shall have been duly
approved by the holders of Company Stock, and except as otherwise agreed to in
writing in advance by Purchaser, against each of the following actions (other
than the transactions contemplated by, or required by, the Stock Purchase
Agreement and the Related Agreements): (A) any extraordinary corporate
transaction, such as a merger, consolidation or other business combination
involving the Company or its Subsidiaries; (B) a sale, lease or transfer of a
material amount of assets of the Company or its Subsidiaries, or a
reorganization, recapitalization, dissolution or liquidation of the Company or
its Subsidiaries; (C) any change in a majority of the Persons who constitute the
board of directors of the Company; (D) any change in the present capitalization
of the Company or any amendment of the Company's Certificate of Incorporation or
Bylaws; (E) any other material change in the Company's corporate structure or
business; or (F) any other action involving the Company or its Subsidiaries
which is intended, or could reasonably be expected, to impede, interfere with,
delay, postpone, or materially adversely affect the transactions contemplated by
the Stock Purchase Agreement, the Related Agreements and this Agreement.

            (b) In the event of a stock dividend or distribution, or any change
in the Company Stock by reason of any stock dividend, split-up,
recapitalization, combination, exchange of shares or the like, the term "Shares"
shall be deemed to refer to and include the Shares as well as all such stock
dividends and distributions and any shares into which or for which any or all of
the Shares may be changed or exchanged.

         3. Other Representations, Warranties and Covenants. The Stockholder
hereby represents, warrants and covenants to Purchaser as follows:

            (a) Ownership of Shares. The Stockholder is, as of the date hereof,
the record holder of and Beneficially Owns the number of shares of Company Stock
set forth opposite the Stockholder's name on Schedule I hereto. As of the date
hereof, the Shares set forth opposite the Stockholder's name on Schedule I
hereto constitute all of the Shares owned of record or Beneficially Owned by the
Stockholder. The Stockholder has sole voting power or sole power to issue
instructions with respect to the matters covered hereby.

            (b) Power; Binding Agreement. The Stockholder has the legal

execution, delivery and performance of this Agreement by the Stockholder will
not violate any other agreement to which the Stockholder is a party including,
without limitation, any other voting agreement, stockholders agreement, voting
trust or similar agreement. This Agreement has been duly and validly executed
and delivered and authorized, to the extent required, by the Stockholder and
constitutes a valid and binding agreement of the Stockholder, enforceable
against the Stockholder in accordance with its terms. There is no beneficiary or
holder of a voting trust certificate or other interest of any trust of which the
Stockholder is a trustee whose consent is required for the execution and
delivery of this Agreement or the consummation by the Stockholder of the
transactions contemplated hereby.

            (c) No Conflicts. (i) No filing with, and no permit, authorization,
consent or approval of, any state or federal public body or authority is
necessary for the execution of this Agreement by the Stockholder and the
consummation by the Stockholder of the transactions contemplated hereby, and
(ii) none of the execution and delivery of this Agreement by the Stockholder,
the consummation by the Stockholder of the transactions contemplated hereby or
compliance by the Stockholder with any of the provisions hereof shall (A) result
in a violation or breach of, or constitute (with or without notice or lapse of
time or both) a default (or give rise to any third party right of termination,
cancellation, material modification or acceleration) under any of the terms,
conditions or provisions of any note, bond, mortgage, indenture, license,
contract, commitment, arrangement, understanding, agreement or other instrument
or obligation of any kind to which the Stockholder is a party or by which the
Stockholder or any of the Stockholder's properties or assets may be bound, or
(B) violate any order, writ, injunction, decree, judgment, order, statute, rule
or regulation applicable to the Stockholder or any of the Stockholder's
properties or assets.

            (d) Proxies and Non-Interference. Beginning on the date hereof and
continuing until this Agreement terminates pursuant to Section 4, the
Stockholder shall not, directly or indirectly, (i) except as contemplated by
this Agreement, grant any proxies or powers of attorney, deposit any Shares into
a voting trust or enter into or amend a voting agreement with respect to any
Shares, or (ii) take any action that would have the effect of preventing or
disabling the Stockholder from performing the Stockholder's obligations under
this Agreement.

            (e) Standstill. During the ten (10) Trading Days immediately
preceding the Closing Date, and during the period commencing fifteen (15)
Trading Days prior to the Adjustment Period and continuing until the expiration
of the Adjustment Period, without the prior written consent of Purchaser, the
Stockholder shall not (i) (x) in any manner acquire, agree to acquire or make
any proposal to acquire, or (y) in any manner Transfer (as hereinafter defined),
directly or indirectly shares of Common Stock of the Company, (ii) make or in
any way participate, directly or indirectly, in any "solicitation" of "proxies"
(as such rules are used in the proxy rules of the Securities & Exchange
Commission) to vote, or seek to advise or influence any person with respect to
the voting of, any shares of Common Stock of the Company, or (iii) form, join or
in any way participate in a "group" (within the meaning of Section 13(d) of the
Exchange Act) with respect to any shares of Common Stock of the Company.

            (f) Reliance by Purchaser. The Stockholder understands and
acknowledges that Purchaser is entering into the Stock Purchase Agreement in
reliance upon the Stockholder's execution and delivery of this Agreement.

            (g) Further Assurances. From time to time, at the other party's
request and without further consideration, each party hereto shall execute and
deliver such additional documents and take all such further lawful action as may
be necessary or desirable to consummate and make effective, in the most
expeditious manner practicable, the transactions contemplated by this Agreement.

         4. Termination. This Agreement shall terminate only upon, and
simultaneously with, the termination of the Stock Purchase Agreement in
accordance with its terms; provided, however, that no such termination shall
relieve any party of liability for a breach hereof prior to termination.

         5. Stockholder Capacity. No Person executing this Agreement who is or
becomes during the term hereof a director of the Company makes any agreement or
understanding herein in his or her capacity as such director. The Stockholder
signs solely in his or her capacity as the record and/or Beneficial Owner of, or
the trustee of a trust whose beneficiaries are the Beneficial Owners of, the
Stockholder's Shares.

         6. Miscellaneous.

            (a) Entire Agreement. This Agreement constitutes the entire
agreement between the parties with respect to the subject matter hereof and
supersede all other prior agreements and understandings, both written and oral,
between the parties with respect to the subject matter hereof.

            (b) Restriction on Transfers. Prior to the Stockholder Meeting, this
Agreement and the obligations hereunder shall attach to the Stockholder's Shares
and shall be binding upon any Person to which legal or Beneficial Ownership of
such Shares shall pass, whether by operation of law or otherwise, including,
without limitation, the Stockholder's heirs, guardians, administrators or
successors. Prior to the Stockholder Meeting, the Stockholder shall not sell,
agree to sell, make any proposal to sell, transfer, pledge, assign or otherwise
dispose of (whether by operation of law or otherwise) (collectively,
"Transfer"), or enter into any contract, option or other arrangement with
respect to the Transfer of any of the Stockholder's Shares, unless as a
condition of such Transfer the transferee agrees in writing to be bound by the
terms and conditions of this Agreement. After the Stockholder Meeting and until
the earliest of (x) the date upon which this Agreement terminates pursuant to
Section 4, (y) the period ending on the fifth anniversary after the Closing
Date, and (z) the date Purchaser and its successors and assigns no longer
beneficially own in the aggregate more than fifty percent (50%) of the number of
Initial Shares and Additional Shares originally issued to Purchaser, the
Stockholder shall not Transfer any of the Stockholder's Shares, unless (i) such
Transfer is permitted by Section 3(e), and (ii) if such Transfer is made to a
Related Party, as a condition of such Transfer the transferee agrees in writing
to be bound by the terms and conditions of this Agreement.

            (c) Legends. The Stockholder hereby acknowledges and agrees the
Company shall place a legend on the shares of Company Stock so as to indicate
that all holders thereof shall be subject to the terms and conditions of this
Agreement.

            (d) Assignment. Neither this Agreement nor any of the rights,
interests or obligations hereunder may be assigned or delegated by the
Stockholder or Purchaser without the prior written consent of the other party
and any purported assignment or delegation in violation hereof shall be null and
void, provided, however, that Purchaser may assign all or any part of its
rights, interests and obligations hereunder to any Affiliate of Purchaser;
provided, that no such assignment before the Closing Date by Purchaser shall
relieve Purchaser of its obligations hereunder.

            (e) Amendments, Waivers, Etc. This Agreement may not be amended,
changed, supplemented, waived or otherwise modified or terminated with respect
to the Stockholder, except upon the execution and delivery of a written
agreement executed by the parties hereto; provided that Schedule I hereto may be
supplemented by Purchaser by other relevant information concerning the
Stockholder of the Company without the agreement of the other party hereto.

This Voting Agreement (this "Agreement"), dated as of August 17, 1999 among
Churchill Environmental & Industrial Equity Partners, L.P. a limited partnership
organized under the laws of the State of Delaware ("Purchaser"), and Kevin M.
Clark, a stockholder (the "Stockholder") of Asche Transportation Services, Inc.,
a Delaware corporation (the "Company").

                                   WITNESSETH:

         WHEREAS, concurrently herewith, Purchaser and the Company are entering
into a Stock Purchase Agreement (as such agreement may hereafter be amended from
time to time, the "Stock Purchase Agreement"), pursuant to which the Purchaser
will purchase from the Company shares of Common Stock of the Company, par value
$.0001 per share (the "Common Stock"); and

         WHEREAS, as an inducement and a condition to entering into the Stock
Purchase Agreement, Purchaser has required that the Stockholder agree, and the
Stockholder has agreed, to enter into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual premises,
representations, warranties, covenants and agreements contained herein, the
parties hereto, intending to be legally bound, hereby agree as follows:

securities Beneficially Owned by a Person shall not include securities which are
actually owned by other Persons but which such Person may be deemed to

approved by the holders of Company Stock, and except as otherwise agreed to in
writing in advance by Purchaser, against each of the following actions (other

Agreement and the Related Agreements): (A) any extraordinary corporate
transaction, such as a merger, consolidation or other business combination

shall be deemed to refer to and include the Shares as well as all such stock
dividends and distributions and any shares into which or for which any or all of
the Shares may be changed or exchanged.

            (c) No Conflicts. (i) No filing with, and no permit, authorization,
consent or approval of, any state or federal public body or authority is
necessary for the execution of this Agreement by the Stockholder and the
consummation by the Stockholder of the transactions contemplated hereby, and
(ii) none of the execution and delivery of this Agreement by the Stockholder,
the consummation by the Stockholder of the transactions contemplated hereby or

time or both) a default (or give rise to any third party right of termination,
cancellation, material modification or acceleration) under any of the terms,
conditions or provisions of any note, bond, mortgage, indenture, license,
contract, commitment, arrangement, understanding, agreement or other instrument
or obligation of any kind to which the Stockholder is a party or by which the
Stockholder or any of the Stockholder's properties or assets may be bound, or
(B) violate any order, writ, injunction, decree, judgment, order, statute, rule
or regulation applicable to the Stockholder or any of the Stockholder's
properties or assets.

            (d) Proxies and Non-Interference. Beginning on the date hereof and
continuing until this Agreement terminates pursuant to Section 4, the
Stockholder shall not, directly or indirectly, (i) except as contemplated by
this Agreement, grant any proxies or powers of attorney, deposit any Shares into

Shares, or (ii) take any action that would have the effect of preventing or
disabling the Stockholder from performing the Stockholder's obligations under
this Agreement.

any proposal to acquire, or (y) in any manner Transfer (as hereinafter defined),
directly or indirectly shares of Common Stock of the Company, (ii) make or in
any way participate, directly or indirectly, in any "solicitation" of "proxies"

Commission) to vote, or seek to advise or influence any person with respect to
the voting of, any shares of Common Stock of the Company, or (iii) form, join or
in any way participate in a "group" (within the meaning of Section 13(d) of the
Exchange Act) with respect to any shares of Common Stock of the Company.

            (f) Reliance by Purchaser. The Stockholder understands and

         4. Termination. This Agreement shall terminate only upon, and
simultaneously with, the termination of the Stock Purchase Agreement in
accordance with its terms; provided, however, that no such termination shall
relieve any party of liability for a breach hereof prior to termination.

         5. Stockholder Capacity. No Person executing this Agreement who is or
becomes during the term hereof a director of the Company makes any agreement or
understanding herein in his or her capacity as such director. The Stockholder
signs solely in his or her capacity as the record and/or Beneficial Owner of, or

respect to the Transfer of any of the Stockholder's Shares, unless as a
condition of such Transfer the transferee agrees in writing to be bound by the
terms and conditions of this Agreement. After the Stockholder Meeting and until
the earliest of (x) the date upon which this Agreement terminates pursuant to
Section 4, (y) the period ending on the fifth anniversary after the Closing
Date, and (z) the date Purchaser and its successors and assigns no longer
beneficially own in the aggregate more than fifty percent (50%) of the number of
Initial Shares and Additional Shares originally issued to Purchaser, the
Stockholder shall not Transfer any of the Stockholder's Shares, unless (i) such
Transfer is permitted by Section 3(e), and (ii) if such Transfer is made to a
Related Party, as a condition of such Transfer the transferee agrees in writing
to be bound by the terms and conditions of this Agreement.

            (c) Legends. The Stockholder hereby acknowledges and agrees the
Company shall place a legend on the shares of Company Stock so as to indicate
that all holders thereof shall be subject to the terms and conditions of this
Agreement.

            (d) Assignment. Neither this Agreement nor any of the rights,
interests or obligations hereunder may be assigned or delegated by the
Stockholder or Purchaser without the prior written consent of the other party
and any purported assignment or delegation in violation hereof shall be null and
void, provided, however, that Purchaser may assign all or any part of its
rights, interests and obligations hereunder to any Affiliate of Purchaser;
provided, that no such assignment before the Closing Date by Purchaser shall
relieve Purchaser of its obligations hereunder.

            (e) Amendments, Waivers, Etc. This Agreement may not be amended,
changed, supplemented, waived or otherwise modified or terminated with respect
to the Stockholder, except upon the execution and delivery of a written

Stockholder of the Company without the agreement of the other party hereto.

            (g) Severability. Whenever possible, each provision or portion of
any provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable law but if any provision or portion of any
provision of this Agreement is held to be invalid, illegal or unenforceable in

contained herein.

            (h) Specific Performance. Each of the parties hereto recognizes and
acknowledges that a breach by it of any covenant or agreement contained in this
Agreement will cause the other party to sustain damages for which it would not
have an adequate remedy at law for money damages, and therefore each of the
parties hereto agrees that in the event of any such breach the aggrieved party
shall be entitled to the remedy of specific performance of such covenants and
agreements and injunctive and other equitable relief in addition to any other
remedy to which it may be entitled, at law or in equity.

            (i) Remedies Cumulative. All rights, powers and remedies provided
under this Agreement or otherwise available in respect hereof at law or in
equity shall be cumulative and not alternative, and the exercise of any thereof
by any party shall not preclude the simultaneous or later exercise of any other
such right, power or remedy by such party.

            (j) No Waiver. The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise any such or other right, power or remedy or to
demand such compliance.

            (k) No Third Party Beneficiaries. This Agreement is not intended to
be for the benefit of, and shall not be enforceable by, any Person who or which
is not a party hereto.

relieve Purchaser of its obligations hereunder.

            (e) Amendments, Waivers, Etc. This Agreement may not be amended,
changed, supplemented, waived or otherwise modified or terminated with respect

            (g) Severability. Whenever possible, each provision or portion of
any provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable law but if any provision or portion of any
provision of this Agreement is held to be invalid, illegal or unenforceable in

reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision or portion of any provision had never been
contained herein.

            (h) Specific Performance. Each of the parties hereto recognizes and
acknowledges that a breach by it of any covenant or agreement contained in this
Agreement will cause the other party to sustain damages for which it would not
have an adequate remedy at law for money damages, and therefore each of the
parties hereto agrees that in the event of any such breach the aggrieved party
shall be entitled to the remedy of specific performance of such covenants and
agreements and injunctive and other equitable relief in addition to any other
remedy to which it may be entitled, at law or in equity.

            (i) Remedies Cumulative. All rights, powers and remedies provided
under this Agreement or otherwise available in respect hereof at law or in
equity shall be cumulative and not alternative, and the exercise of any thereof
by any party shall not preclude the simultaneous or later exercise of any other
such right, power or remedy by such party.

            (j) No Waiver. The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise any such or other right, power or remedy or to
demand such compliance.

            (k) No Third Party Beneficiaries. This Agreement is not intended to
be for the benefit of, and shall not be enforceable by, any Person who or which
is not a party hereto.

to the exclusive jurisdiction of the U.S. Federal courts in the Southern
District of the State of New York.

This Voting Agreement (this "Agreement"), dated as of August 17, 1999 among
Churchill Environmental & Industrial Equity Partners, L.P. a limited partnership
organized under the laws of the State of Delaware ("Purchaser"), and Gary I.
Goldberg, a stockholder (the "Stockholder") of Asche Transportation Services,
Inc., a Delaware corporation (the "Company").

                                   WITNESSETH:

         WHEREAS, concurrently herewith, Purchaser and the Company are entering
into a Stock Purchase Agreement (as such agreement may hereafter be amended from
time to time, the "Stock Purchase Agreement"), pursuant to which the Purchaser
will purchase from the Company shares of Common Stock of the Company, par value
$.0001 per share (the "Common Stock"); and

         WHEREAS, as an inducement and a condition to entering into the Stock
Purchase Agreement, Purchaser has required that the Stockholder agree, and the
Stockholder has agreed, to enter into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual premises,
representations, warranties, covenants and agreements contained herein, the
parties hereto, intending to be legally bound, hereby agree as follows:

securities Beneficially Owned by a Person shall not include securities which are
actually owned by other Persons but which such Person may be deemed to

            (g) Severability. Whenever possible, each provision or portion of
any provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable law but if any provision or portion of any
provision of this Agreement is held to be invalid, illegal or unenforceable in

reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision or portion of any provision had never been
contained herein.

            (h) Specific Performance. Each of the parties hereto recognizes and
acknowledges that a breach by it of any covenant or agreement contained in this
Agreement will cause the other party to sustain damages for which it would not
have an adequate remedy at law for money damages, and therefore each of the
parties hereto agrees that in the event of any such breach the aggrieved party
shall be entitled to the remedy of specific performance of such covenants and
agreements and injunctive and other equitable relief in addition to any other
remedy to which it may be entitled, at law or in equity.

            (i) Remedies Cumulative. All rights, powers and remedies provided
under this Agreement or otherwise available in respect hereof at law or in
equity shall be cumulative and not alternative, and the exercise of any thereof
by any party shall not preclude the simultaneous or later exercise of any other
such right, power or remedy by such party.

            (j) No Waiver. The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise any such or other right, power or remedy or to
demand such compliance.

            (k) No Third Party Beneficiaries. This Agreement is not intended to
be for the benefit of, and shall not be enforceable by, any Person who or which

                            JALOVEC VOTING AGREEMENT

This Voting Agreement (this "Agreement"), dated as of August 17, 1999 among
Churchill Environmental & Industrial Equity Partners, L.P. a limited partnership
organized under the laws of the State of Delaware ("Purchaser"), and James A.
Jalovec, a stockholder (the "Stockholder") of Asche Transportation Services,
Inc., a Delaware corporation (the "Company").

                                   WITNESSETH:

         WHEREAS, concurrently herewith, Purchaser and the Company are entering
into a Stock Purchase Agreement (as such agreement may hereafter be amended from
time to time, the "Stock Purchase Agreement"), pursuant to which the Purchaser
will purchase from the Company shares of Common Stock of the Company, par value
$.0001 per share (the "Common Stock"); and

         WHEREAS, as an inducement and a condition to entering into the Stock
Purchase Agreement, Purchaser has required that the Stockholder agree, and the
Stockholder has agreed, to enter into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual premises,
representations, warranties, covenants and agreements contained herein, the
parties hereto, intending to be legally bound, hereby agree as follows:

         1. Definitions. Capitalized terms used and not defined herein have the

amended (the "Exchange Act")), including pursuant to any agreement, arrangement
or understanding, whether or not in writing. Notwithstanding the foregoing,
securities Beneficially Owned by a Person shall not include securities which are
actually owned by other Persons but which such Person may be deemed to
Beneficially Own under Rule 13d-3 under the Exchange Act solely because such
Person may be deemed to be part of a "group" with such other Persons as within
the meaning of Section 13(d)(3) of the Exchange Act.

            (c) "Related Party" or "Related Parties" means Affiliates of the

         2. Provisions Concerning Company Stock.

            (a) The Stockholder hereby agrees that during the period commencing
on the date hereof and continuing for so long as the Stockholder holds any
shares of Common Stock, at any meeting of the



<PAGE>   2

consent of the holders of Company Stock, the Stockholder shall vote (or cause to
be voted) all shares of Company Stock held of record or Beneficially Owned by
the Stockholder, whether heretofore owned or hereafter acquired (collectively,
the "Shares"): (i) in favor of the Charter Amendment; (ii) in favor of the
Investment Proposal and the execution and delivery by the Company of the Stock
Purchase Agreement and the Related Agreements, the approval of the terms thereof
and each of the other transactions and actions contemplated thereby (and the
matters related to the consummation thereof); (iii) in favor of the Charter and
By-Law Amendments; (iv) against any action or agreement that would result in a
breach in any respect of any covenant, representation or warranty or any other
obligation or agreement of the Company under the Stock Purchase Agreement or the
Related Agreements or of the Stockholder under this Agreement or that would
result in any of the conditions to the obligations of the Company under the
Stock Purchase Agreement not being fulfilled; and (v) until the Investment
Proposal shall have been duly approved by the holders of Company Stock, and
except as otherwise agreed to in writing in advance by Purchaser, against each
of the following actions (other than the transactions contemplated by, or
required by, the Stock Purchase Agreement and the Related Agreements): (A) any
extraordinary corporate transaction, such as a merger, consolidation or other
business combination involving the Company or its Subsidiaries; (B) a sale,
lease or transfer of a material amount of assets of the Company or its
Subsidiaries, or a reorganization, recapitalization, dissolution or liquidation

Certificate of Incorporation or Bylaws; (E) any other material change in the
Company's corporate structure or business; or (F) any other action involving the
Company or its Subsidiaries which is intended, or could reasonably be expected,
to impede, interfere with, delay, postpone, or materially adversely affect the
transactions contemplated by the Stock Purchase Agreement, the Related
Agreements and this Agreement.

         (b) In the event of a stock dividend or distribution, or any change in
the Company Stock by reason of any stock dividend, split-up, recapitalization,
combination, exchange of shares or the like, the term "Shares" shall be deemed
to refer to and include the Shares as well as all such stock dividends and
distributions and any shares into which or for which any or all of the Shares
may be changed or exchanged.

         3. Other Representations, Warranties and Covenants. The Stockholder
hereby represents, warrants and covenants to Purchaser as follows:

         (a) Ownership of Shares. The Stockholder is, as of the date hereof, the

instructions with respect to the matters covered hereby.

         (b) Power; Binding Agreement. The Stockholder has the legal capacity,

            (c) No Conflicts. (i) No filing with, and no permit, authorization,
consent or approval of, any state or federal public body or authority is
necessary for the execution of this Agreement by the Stockholder and the
consummation by the Stockholder of the transactions contemplated hereby, and
(ii) none of the execution and delivery of this Agreement by the Stockholder,
the consummation by the Stockholder of the transactions contemplated hereby or
compliance by the Stockholder with any of the provisions hereof shall (A) result
in a violation or breach of, or constitute (with or without notice or lapse of
time or both) a default (or give rise to any third party right of termination,
cancellation, material modification or acceleration) under any of the terms,
conditions or provisions of any note, bond, mortgage, indenture, license,
contract, commitment, arrangement, understanding, agreement or other instrument
or obligation of any kind to which the Stockholder is a party or by which the
Stockholder or any of the Stockholder's properties or assets may be bound, or
(B) violate any order, writ, injunction, decree, judgment, order, statute, rule
or regulation applicable to the Stockholder or any of the Stockholder's
properties or assets.

            (d) Proxies and Non-Interference. Beginning on the date hereof and
continuing until this Agreement terminates pursuant to Section 4, the
Stockholder shall not, directly or indirectly, (i) except as contemplated by
this Agreement, grant any proxies or powers of attorney, deposit any Shares into
a voting trust or enter into or amend a voting agreement with respect to any
Shares, or (ii) take any action that would have the effect of preventing or
disabling the Stockholder from performing the Stockholder's obligations under
this Agreement.

            (e) Standstill. During the ten (10) Trading Days immediately

any proposal to acquire, or (y) in any manner Transfer, directly or indirectly
shares of Common Stock of the Company, (ii) make or in any way participate,
directly or indirectly, in any "solicitation" of "proxies" (as such rules are

seek to advise or influence any person with respect to the voting of, any shares
of Common Stock of the Company, or (iii) form, join or in any way participate in
a "group" (within the meaning of Section 13(d) of the Exchange Act) with respect
to any shares of Common Stock of the Company.

            (f) Reliance by Purchaser. The Stockholder understands and
acknowledges that Purchaser is entering into the Stock Purchase Agreement in
reliance upon the Stockholder's execution and delivery of this Agreement.

            (g) Further Assurances. From time to time, at the other party's
request and without further consideration, each party hereto shall execute and
deliver such additional documents and take all such further lawful action as may
be necessary or desirable to consummate and make effective, in the most
expeditious manner practicable, the transactions contemplated by this Agreement.

Or to such other address as the Person to whom notice is given may have
previously furnished to the others in writing in the manner set forth above.

            (g) Severability. Whenever possible, each provision or portion of
any provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable law but if any provision or portion of any
provision of this Agreement is held to be invalid, illegal or unenforceable in
any respect under any applicable law or rule in any jurisdiction, such
invalidity, illegality or unforceability will not affect any other provision or
portion of any provision in such jurisdiction, and this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision or portion of any provision had never been
contained herein.

            (h) Specific Performance. Each of the parties hereto recognizes and
acknowledges that a breach by it of any covenant or agreement contained in this
Agreement will cause the other party to sustain damages for which it would not
have an adequate remedy at law for money damages, and therefore each of the
parties hereto agrees that in the event of any such breach the aggrieved party
shall be entitled to the remedy of specific performance of such covenants and
agreements and injunctive and other equitable relief in addition to any other
remedy to which it may be entitled, at law or in equity.

            (i) Remedies Cumulative. All rights, powers and remedies provided
under this Agreement or otherwise available in respect hereof at law or in
equity shall be cumulative and not alternative, and the exercise of any thereof
by any party shall not preclude the simultaneous or later exercise of any other
such right, power or remedy by such party.

            (j) No Waiver. The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise any such or other right, power or remedy or to
demand such compliance.

            (k) No Third Party Beneficiaries. This Agreement is not intended to
be for the benefit of, and shall not be enforceable by, any Person who or which
is not a party hereto.

            (l) Governing Law. This Agreement shall be governed by and construed
in accordance with laws of the State of New York without giving regard to the
principles of conflicts of law.

            (m) Jurisdiction. Each of the parties hereto hereby agrees to submit
to the exclusive jurisdiction of the U.S. Federal courts in the Southern
District of the State of New York.

            (n) Descriptive Headings. The descriptive headings used herein are
inserted for convenience of reference only and are not intended to be part of or
to affect the meaning or interpretation of this Agreement.

            (o) Counterparts. This Agreement may be executed in counterparts,
each of which shall be deemed to be an original, but all of which, taken
together, shall constitute one and the same Agreement.
