                             CONSULTING AGREEMENT

     THIS CONSULTING AGREEMENT (the "Agreement") is made as of the 1st day of
October, 1999, by and between STEVEN E. SANDERSON, an individual residing at
180 Holly Ave., Carpinteria, California 93013 ("Consultant"), and McLAREN
AUTOMOTIVE GROUP, INC., a Delaware corporation with its principal office located
at 32233 West Eight Mile Road, Livonia, Michigan 48152 (the "Corporation").

                             W I T N E S S E T H:

     WHEREAS, the Corporation is in the business of designing, fabricating,
developing, validating and certifying engines and related components and
products for the automotive industry (the "Business");

     WHEREAS, Consultant has significant experience and knowledge of the
Corporation's finances and financial operations as well as the Business;

     WHEREAS, Consultant has been employed by the Corporation pursuant to an
Employment Agreement with the Corporation dated May 1, 1999 (the "Employment
Agreement");

     WHEREAS, the Corporation and Consultant wish to terminate the Employment
Agreement;

     WHEREAS, Consultant wishes to resign as the Chief Financial Officer and
Secretary of the Corporation as set forth in Schedule A attached hereto, and the
Corporation wishes to accept such resignation; and

     WHEREAS, the Corporation desires to retain the services of Consultant as a
consultant to provide the Corporation with advice regarding the operations of
the Corporation and the Business on the terms and conditions contained herein.

     NOW, THEREFORE, in consideration of the covenants and conditions contained
herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows:

     1.  Recitals.  The foregoing recitals are hereby incorporated into this
Agreement and made a part hereof.

     2.  Consulting Services.  During the Term of this Agreement (as defined
below), Consultant agrees that he will make himself available to the Corporation
during normal business hours to consult with the Corporation and to do all
things reasonably requested by the President or Board of Directors of the
Corporation.  Consultant will be available to the Corporation via a cellular
phone which will be furnished to Consultant by the Corporation.

     3.  Term.  The term of this Agreement shall commence on the date hereof and
shall continue until May 31, 2000, unless earlier terminated in accordance with
Section 10 of this Agreement (the "Term").

     4.  Compensation.  For all services rendered by Consultant hereunder, the
Corporation shall pay Consultant Forty-Seven Thousand Six Hundred Dollars
($47,600.00) (the "Consulting Fee"), payable at a rate of Five Thousand Nine
Hundred Fifty Dollars ($5,950.00) per month, which shall be remitted to
Consultant on the first day of each month.  In addition, the Corporation shall
pay Consultant Four Hundred Seven and 55/100 Dollars ($407.55) per month, or
such amount as is necessary, to cover the costs of Consultant's COBRA coverage.

     5.  Stock Options.  During the Term, the Corporation shall grant to
Consultant Seventeen Thousand Five Hundred (17,500) options to purchase the
common stock of the Corporation (the "Options").  The price and the exercise
schedule for the Options shall be the same as that for options granted to
executives of the Corporation.  Neither the termination of Consultant's
Employment Agreement nor Consultant's resignation as the Corporation's Chief
Financial Officer and Secretary shall affect Consultant's retention of

                                       1
<PAGE>

all unexercised stock options which were granted to him during the term of his
employment with the Corporation.

     6.  Independent Contractor Status.  Nothing contained in this Agreement
shall be construed to constitute Consultant as an employee or agent of the
Corporation, nor shall either party have any authority to bind the other in any
respect, it being intended and understood that Consultant shall remain an
independent contractor responsible for his own actions.  Consultant acknowledges
that the Corporation has no obligation to and will not withhold income or
payroll taxes with respect to the duties performed by Consultant and Consultant
hereby agrees to pay all such taxes.

     7.  Indemnity.  Each party shall indemnify, protect and hold harmless the
other party from and against all expenses, claims and liabilities arising out of
or relating to a breach of that party's obligations hereunder.

     8.  Confidentiality.  Consultant acknowledges that certain of the
Corporation's business information is confidential.  Therefore, Consultant
agrees that Consultant shall not use or reveal, divulge or make known to any
person, firm, company, corporation or other entity any Proprietary Information
except as required by law or court order.  "Proprietary Information" is any and
all information or data, whether in writing, or learned orally, by observation
or other sensory detection, whether learned by Consultant during his employment
relationship with the Corporation or during the Term, as well as that
information relating to any product, product design, research, development,
formula, manufacturing process, method of distribution or delivery, knowhow,
trade secret, customer list, contract term, customer pricing, supplier list or
price, business strategy, compensation, plan or practice, financial and
operating records, software, technology, sales data, information or other
records, lists or documents used by the Corporation in the operation of the
Business or otherwise.  All Proprietary Information and other Corporation
property shall be returned to the Corporation at the termination of Consultant's
consulting relationship with the Corporation.  The Proprietary Information and
all other information relating to the Corporation shall belong to and remain the
property of the Corporation.  Upon termination of this Agreement, Consultant
shall leave with the Corporation all such information in any way relating to the
Corporation or the Business.  However, Proprietary Information shall not be
deemed to include information which:  (a) at the time of disclosure is properly
in the public domain or thereafter properly becomes part of the public domain by
publication or otherwise through no fault or act of Consultant or his agents, or
(b) is independently made available to Consultant in good faith by a third party
who has not violated a confidential relationship with the Corporation.

     9.  Discoveries and Works.  Consultant agrees and acknowledges that all
discoveries and works made or conceived by Consultant as of the date hereof
while in the employ of the Corporation, or during the Term, individually or with
others, that relate to the Business or the Corporation's activities (including
actual or demonstrably anticipated research or development of the Corporation),
or result from any work performed by Consultant for the Corporation shall be
owned by the Corporation.  The term "discoveries and works" includes, but is not
limited to, reports, financial analyses or other financial information,
improvements, processes and works of authorship.  Consultant shall:  (a)
promptly notify, make full disclosure to, and execute and deliver any documents
requested by, the Corporation to evidence or better assure title to such
discoveries and works in the Corporation, (b)  assist the Corporation in
obtaining or maintaining for itself at its own expense United States and foreign
patents, copyrights, trade secret protection or other protection of any and all
such discoveries and works, and (c)  promptly execute, whether during the Term
or thereafter, all applications or other endorsements necessary or appropriate
to maintain patents and other rights for the Corporation and to protect its
title thereto.  Any discoveries and works which, within six (6) months after the
termination of the Term, are made, disclosed, reduced to a tangible or written
form or description, or are reduced to practice by Consultant and which pertain
to the business carried on or products or services being sold or developed by
the Corporation at the time of such termination shall, as between Consultant and
the Corporation, be deemed to have been made during the Term and shall be owned
by the Corporation.  The foregoing does not apply to a discovery or work that
Consultant has developed entirely on his own time without using the
Corporation's equipment, supplies, facilities or trade secret information except
for those discoveries and works that either:  (i)  relate at the time of
conception or reduction to practice of the discoveries and works to the
Corporation's Business, or actual or demonstrably anticipated research or
development of the Corporation; or (ii)  result from any work performed by
Consultant for the Corporation.

     10.  Termination.  This Agreement may be terminated by either party after
November 29, 1999, upon thirty (30) days written notice to the other party.  In
the event this Agreement is terminated by the Corporation, the Corporation shall
remit to Consultant the unpaid portion of the Consulting Fee.  In the event this
Agreement is terminated by Consultant, the Corporation shall remit to Consultant
an amount equal to fifty percent (50%) of the unpaid portion of the Consulting
Fee.  Upon termination of the Agreement, the Corporation's obligation to provide
a cellular phone to Consultant and to pay Consultant for COBRA coverage as set
forth in Section 4 shall cease.

     11.  Complete Agreement; Termination of Employment Agreement.  This
Agreement is the complete agreement between the parties with respect to the
subject matter hereof.  This Agreement supersedes all previous agreements
between Consultant and the Corporation, including the Employment Agreement, each
of the Corporation and Consultant acknowledge and agree that neither party shall
have any further obligations to the other under the Employment Agreement.
Neither this Agreement nor any provision hereof may be changed, waived,
discharged or terminated orally, but only by an instrument in writing signed by
the parties.

     12.  Release.  Consultant agrees, in consideration of the Corporation's
entering into this Agreement and the compensation to be paid to Consultant
hereunder, not to sue and Consultant hereby releases and forever discharges the
Corporation, and its predecessors, assigns, and affiliates, and each of their
past and present officers, directors, employees and agents, both in their
individual and representative capacities, from any and all claims, demands,
actions and causes of action, damages, costs, payments and expenses of every
kind, nature or description which may exist as of the date of this Agreement
arising out of or relating to facts or circumstances, whether known or unknown,
in existence on the date of this Agreement, including but not limited to those
arising out of or related to Consultant's employment relationship with the
Corporation, its predecessor, or otherwise.  Consultant agrees that this release
includes, but is not limited to, a voluntary waiver of all claims of
discrimination, including age discrimination, against the Corporation, under
both federal and state law.  Specifically, Consultant agrees that this release
includes a voluntary waiver of all claims under the Age Discrimination in
Employment Act of 1967, 29 U.S.C. (S)(S) 621 to 634; the Civil Rights Act of
1871, 42 U.S.C. (S)(S) 1981; the Civil Rights Act of 1964, 44 U.S.C. (S) 2000e,
et seq.; the employment laws and regulations of the State of Michigan, including
the Elliott-Larsen Civil Rights Act; the employment laws and regulations of the
State of California, including the Fair Employment and Housing Act; and/or any
claims growing out of any legal restrictions on the Corporation's right to
terminate its employees.  Consultant agrees that this also includes a voluntary
waiver and release of any claims based on any contract or promise, express or
implied.  Consultant acknowledges that Consultant fully understands and agrees
that the release contained in this Agreement may be used by Corporation as a
complete defense to any claim which hereafter may be asserted by Consultant or
other persons or agencies on behalf of Consultant in any suit or claim against
Corporation for or on account of any matter or thing whatsoever arising out of
the employment relationship between Consultant and Corporation.

     13.  Injunctive Relief.  Consultant agrees that the remedy of monetary
damages for any breach or threatened breach of the covenants of this Agreement
would be inadequate to remedy fully the breach because any breach or attempted
breach by Consultant would cause immediate, substantial and irreparable loss of
business and profits to the Corporation in an amount which would be impossible
to ascertain.  Accordingly, in the event of any breach or threatened breach of
any of said covenants by Consultant, in addition to any and all other legal and
equitable remedies which may be available, including suit for recovery of actual
damages, the Corporation, and/or any affiliated or related corporation, or any
successor of the Corporation, shall be entitled to equitable relief, including
injunctive relief and specific performance, without the necessity of posting
security or proving actual loss of business to the Corporation by reason of such
breach and, to the extent permissible under applicable law, a temporary
restraining order shall be granted immediately on commencement of any such suit
by the Corporation.  Such remedies will not be the exclusive remedies for any
breach of this Agreement but will be in addition to all other remedies available
under this Agreement or at law or equity to the Corporation.

     14.  Binding Agreement; Successors.  This Agreement shall be binding upon,
inure to the benefit of and be enforceable by the successors, permitted assigns,
heirs, legatees, executors, personal representatives, guardians, custodians,
administrators and conservators of the parties hereto.

                                       3

     15.  Validity.  If any Section, paragraph, sentence, clause or other
provision of this Agreement, or the application of such provision, is held
invalid or unenforceable by a court of competent jurisdiction, such provision
shall be deemed to be modified in a manner consistent with the intent of such
original provision, so as to make it valid and enforceable, and this Agreement,
and the application of such provision to persons or circumstances other than
those with respect to which it would be invalid or unenforceable, shall not be
affected thereby.

     16.  Notices.  Any notices required or permitted to be given under this
Agreement shall be sent by a nationally recognized overnight delivery service
and shall be effective when received by the other party.  For the purposes of
the Paragraph, the addresses of the parties shall be as set forth in the first
paragraph of this Agreement.  Any party may change the address to which such
communications are to be sent by notice to the other parties as provided herein.

     17.  Governing Law; Forum.  This Agreement is a contract made under, and
shall be governed by and construed in accordance with, the law of the State of
Michigan applicable to contracts made and to be performed entirely within such
State and without giving effect to choice of law principles of such State.  Each
of the parties hereto agrees that any legal or equitable action or proceeding
with respect to this Agreement, or any agreement represented herein or entered
in connection herewith or the transactions contemplated hereby shall be brought
only in any court of the State of Michigan, or in any court in the United States
of America sitting in Michigan, and each of the parties hereto hereby submits to
and accepts generally and unconditionally the jurisdiction of those courts with
respect to such party's person and property, and irrevocably consents to the
service of process in connection with any such action or proceeding by the
mailing thereof by registered or certified mail, postage prepaid to each party
at such party's address set forth above.  Nothing in this paragraph shall affect
the right of any party hereto to serve process in any other manner permitted by
law.  Each party hereby irrevocably waives any objection to the laying of venue
of any such action or proceeding in the above described courts.

     18.  Headings.  The section headings herein are for reference purposes only
and shall not affect in any way the meaning or interpretation of this Agreement,
nor are they deemed to constitute a part of this Agreement.

     19.  Waiver.  The failure of either party to exercise or enforce any right
or remedy conferred upon it hereunder shall not be deemed to be a waiver of any
such right or remedy nor operate to bar the exercise or enforcement thereof at
any time thereafter.

     20.  Counterparts.  This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original, but all of which
together shall constitute one and the same instrument.

     IN WITNESS WHEREOF, the parties have executed this Agreement on the date
first above written.

                              NOTICE OF REDEMPTION

                                       OF

                                CLASS A WARRANTS

To the Holders of Outstanding
Class A Warrants of Vion Pharmaceuticals, Inc.

                  We hereby give notice that we are redeeming all of our
outstanding Class A warrants on March 13, 2000. We are exercising this right
pursuant to the terms of the warrant agreement dated as of August 14, 1995
governing our Class A warrants.

TERMS OF REDEMPTION; CESSATION OF RIGHTS

                  Redemption Date:          March 13, 2000

                  Redemption Price:         $.05 per Warrant

                  The right of our Class A warrant holders to exercise their
warrants to purchase shares of our common stock and Class B warrants will
terminate at 5:00 p.m. New York time on March 10, 2000 (one business day prior
to the Redemption Date). After such time, holders of Class A warrants will have
no rights except to receive, upon surrender of their warrants, the Redemption
Price. The Redemption Price is substantially less than either (i) the current
market price of the shares of common stock and Class B warrants receivable upon
exercise of the Class A warrants or (ii) the current price that could be
obtained upon the sale of the Class A warrants in the open market.

REDEMPTION PROCEDURE

                  Payment of the amount to be received on redemption will be
made by us upon the presentation and surrender of the Class A warrants for
payment at any time on or after the Redemption Date. To surrender Class A
warrants for redemption, holders should deliver certificates representing their
Class A warrants to American Stock Transfer & Trust Company, our warrant agent,
at the following address:

                     American Stock Transfer & Trust Company
                           40 Wall Street - 46th Floor
                            New York, New York 10005
                            Telephone: (718) 921-8100

EXERCISE PROCEDURE (EXPIRES 5:00 P.M. NEW YORK TIME ON MARCH 10, 2000)

                  In lieu of surrendering the warrants for redemption, Class A
warrant holders may, at their option, exercise their warrants to purchase our
common stock and Class B warrants.
<PAGE>

Each Class A warrant entitles the holder to purchase at a price of $4.63 one
share of common stock and one Class B warrant.

                  This is not a redemption of our Class B warrants. The Class B
warrants may be exercised at any time prior to their expiration or redemption.
Each Class B warrant entitles the holder to purchase one share of our common
stock at a price of $6.23.

                  The Class A warrants may be exercised by delivery of the Class
A warrant certificates to American Stock Transfer and Trust Company at the
address set forth above under "Redemption Procedure" accompanied by a bank or
certified check made payable to Vion Pharmaceuticals, Inc. for the full amount
of the Exercise Price ($4.63 for each warrant exercised). The subscription form
on the reverse side of each warrant must be completed in full and signed by the
warrant holder and the signature guaranteed by an eligible institution. The
method of delivery of the warrant certificates is at the option and risk of the
holder, but if mail is used, registered mail properly insured is suggested.

                  The warrant certificate and the payment of the Exercise Price
must be received by the warrant agent prior to 5:00 p.m. New York time on March
10, 2000. Warrants which are received after such date will not be exercised, but
will be redeemed. Provided that a notice of exercise and payment is received by
the warrant agent prior to 5:00 p.m. New York time on March 10, 2000,
broker-dealers shall have three business days to deliver warrant certificates to
the warrant agent.

                  ANY WARRANT RECEIVED WHICH IS NOT ACCOMPANIED BY PAYMENT OF
THE EXERCISE PRICE OR WHICH IS RECEIVED WITHOUT THE SUBSCRIPTION FORM HAVING
BEEN COMPLETED AND SIGNED WILL BE DEEMED TO HAVE BEEN DELIVERED FOR REDEMPTION,
AND NOT FOR EXERCISE.

                      IMPORTANT - IMMEDIATE ACTION REQUIRED

                                                               February 11, 2000

Dear Class A Warrant Holder:

                  Vion Pharmaceuticals, Inc. has called for redemption of all of
its outstanding Class A warrants for cash at the redemption price of $.05 per
warrant on March 13, 2000. A copy of the Notice of Redemption, a Prospectus and
our 1998 Annual Report is enclosed.

                  We are entitled to redeem the Class A warrants because we have
satisfied the condition of redemption - namely, that the average closing price
of our common stock exceeded $7.30 for a period of 30 consecutive business days
ending within 15 days of the date of this notice. The Class A warrants are
exercisable at an exercise price of $4.63 for one share of common stock and one
Class B warrant. After 5:00 p.m., New York time on March 10, 2000, the Class A
warrants will no longer be exercisable for shares of common stock and you will
only have the right to receive the redemption price.

                  We urge you to consider the following two alternatives to
redemption which are available to you and which may be more beneficial to you
than redemption:

1.       Exercise of the Class A warrants.

                  Each Class A warrant is exercisable at an exercise price of
$4.63 for one share of our common stock and one Class B warrant. The closing
price of our common stock as reported by the Nasdaq National Market ranged from
a high of $15.25 to a low of $5.88 during the period from December 30, 1999
through February 10, 2000. Current market quotations are available from the
Nasdaq National Market or your broker.

2.       Sale of the Class A warrants in the open market.

                  The Class A warrants may be sold in the open market. The
closing price of our Class A warrants as reported by the Nasdaq SmallCap Market
ranged from a high of $19.13 to a low of $2.81 during the period from December
30, 1999 through February 10, 2000. You should consult your own broker as to the
procedure for selling your warrants and for current market quotations.
<PAGE>

                  The procedures for exercise and/or redemption of the warrants
are set forth in the accompanying Notice of Redemption.

                  Questions and requests for assistance should be directed to
our information agent, Corporate Investor Communications, Inc. at
1-877-842-2409.
