and sale of the Shares hereunder (the "Closing") shall be sub-
ject to the approval of the sale of the Shares hereunder by
the holders of shares of Common Stock and to the approval of

chaser's employment with the Company is terminated, other than
                         -2-

          (b)  subject to clauses (c), (d) and (e) below, 50%

of a material breach by the Company of the Employment Agree-
ment, prior to May 1, 1990;
          (c)  in the event such termination is the result of 
the death or disability (as defined in the Employment Agree-
ment) of the Purchaser, the portion of the Shares determined 
by multiplying the total number of Shares by a fraction, the
numerator of which is the number of complete months during the
period from May 1, 1988 through the date of termination and 
the denominator of which is 24, shall no longer be subject 
to forfeiture;
          (d)  in the event of a Business Combination (as de-
fined in the Employment Agreement), the forfeiture shall cease
to apply to all the Shares simultaneous with the closing of 
the transaction; and
          (e)  in the event of a Change of Control (as defined 
in the Employment Agreement) other than a Business Combina-

tween the Company and the Purchaser (the "Option Agreement"))
that simultaneously will vest on an accelerated basis pursuant 
to clause (b) of the last paragraph of Schedule 1 to the Op-
tion Agreement, shall no longer be subject to forfeiture.  
If and to the extent any portion of the Shares is forfeited to
the Company as aforesaid, (i) the equivalent portion of the
unpaid balance of the Note shall be deemed paid and a notation 
to that effect shall be made by the Company on the face of the
Note, (ii) the Purchaser shall deliver to the Company, within 
ten business days after the forfeiture, stock certificates
representing the forfeited portion of the Shares and (iii) the

puted Income") on the loan evidenced by the Note, and that the
related interest deductions will be available over the initial
five-year term of the Note.  To facilitate the payment by the
Purchaser of his federal income tax liability on the portion 
of the Imputed Income for which there will be no related in-
                               -4-


terest deduction for 1988, the Company shall make a loan (the
"Loan") to the Purchaser, on April 15, 1989, in the amount of 
88% of his federal income tax liability (without taking into
account any offsetting interest deductions) on the Imputed 
Income (the "Imputed Liability"); PROVIDED, HOWEVER, that if, 
on or before August 31, 1988, the Purchaser shall deliver to 
the Company, (a) written notice that he will be taking the
Imputed Liability into account in making his federal quarterly
estimated tax payments and (b) a letter from his accountant
advising that he is required to do so, then the Company shall
make the Loan to the Purchaser in two equal advances on Sep-
tember 15, 1988 and January 15, 1989, respectively.  The 
amount of the Loan shall be determined by the Company's inde-
pendent accountants (whose determination, in the absence of
manifest error, shall be final and binding on the Company and 
the Purchaser), based on the provisions of this Agreement and
assuming a federal income tax rate of 28%, and the Company 
shall cause a copy of a schedule setting forth the calcula-
tions on the basis of which the determination is made to be
provided to the Purchaser within ten business days after the 
date of the Closing.  On the date the Loan (or each advance
thereof) is made, the Purchaser shall execute and deliver to 
the Company a duly executed Secured Promissory Note in the 
form attached as Exhibit C hereto.  If the maturity of the 
Note shall be extended until April 30, 1998 in accordance with
                               -5-


clause (ii) of the second paragraph thereof, the Company shall

$1,326,197.90                           June___, 1988

          FOR VALUE RECEIVED, ROBERT ALVINE (the "Payor")
hereby promises to pay to CHARTER POWER SYSTEMS, INC., a Dela-
ware corporation ("the Company"), the principal sum of One
Million Three Hundred Twenty Six Thousand One Hundred and
Ninety-Seven and 90/100 Dollars ($1,326,197.90), without in-
terest.  Payment of principal is to be made in lawful money of
the United States of America at the offices of the Company or
at such other place as the holder hereof shall designate.
          Subject to the prepayment and acceleration provi-
sions hereinafter set forth, this Note shall mature and be due
and payable in full on April 30, 1993; PROVIDED, HOWEVER, that
(i) if the employment of the Payor with the Company shall have 
been terminated after October 31, 1991 and before May 1, 1993,
other than for "Cause", as defined in the employment agree-
ment, dated May 26, 1988, between the Payor and the Company (a
"Cause Termination"), the maturity of this Note shall be
extended until 18 months after the date of termination of the
Payor's employment with the Company; and (ii) if the employ-
ment of the Payor with the Company shall not have been termi-
nated on or before April 30, 1993, the maturity of this Note
shall be extended until April 30, 1998; PROVIDED, FURTHER, 
that this Note shall mature and be due and payable 18 months

after the date of termination (other than a Cause Termination)
of the Payor's employment with the Company, which termination
shall occur after April 30, 1993.
          This Note is secured by the pledge by the Payor to
the Company of certain shares of common stock of the Company, 
in accordance with the terms of a Pledge and Security Agree-
ment (the "Security Agreement") between the Payor and the Com-
pany, dated June ___, 1988, and in that respect is subject to 
all of the terms, provisions and conditions of the Security
Agreement.
          This Note evidences a loan made by the Company to 
the Payor to enable him to purchase 316,515 shares of common
stock of the Company (the "Shares").  If the Payor shall sell
or transfer any of his Shares or the proceeds thereof, or any
cash (other than cash dividends), securities, or other prop-
erty at any time and from time to time receivable or otherwise
distributed in respect of or in exchange for any or all of the 
Shares (collectively, the "Additional Shares"), there shall be 
due and payable, immediately upon the consummation of the sale
or transfer, a payment of principal hereunder in an amount
equal to the product obtained by multiplying the then out-
standing principal amount of this Note by a fraction, the nu-
merator of which shall be the number of Shares and Additional
Shares then sold or transferred and the denominator of which
shall be the number of Shares and Additional Shares then owned by
the Payor (before giving effect to the sale or transfer).
                               -2-

Nothing in this paragraph shall be deemed to permit any sale
or transfer by the Payor of any Shares or Additional Shares,
to the extent the same otherwise would be prohibited by the
provisions of any other agreement to which the Payor and the
Company are parties.
          If: (i) the Payor fails to make any payment here-
under within ten days after notice from the Company to the
Payor that the payment is due; or (ii) a Cause Termination oc-
curs; or (iii) a Default (as defined in the Security Agree-
ment) shall have occurred under the Security Agreement (each
of the events listed in (i), (ii) and (iii) above being an "Event
of Default" hereunder); the then outstanding principal
balance hereof shall become immediately due and payable.
          The Payor may, at any time and from time to time,
prepay in whole or part, without premium or penalty, the then
outstanding principal balance hereof.
          The Payor hereby agrees to pay all reasonable costs,
fees and expenses incurred by the Company for the collection 
of all sums due hereunder, including reasonable attorneys'
fees and court costs.  The Payor hereby waives presentment,
demand, notice of dishonor, protest and all other demands and
notices in connection with this Note (including any accelera-
tion of the maturity hereof) and further agrees that this Note 
shall be deemed to have been made under and shall be governed 
by the laws of the State of New York in all respects (without
                               -3-

giving effect to the conflicts of law provisions thereof), in-
cluding matters of construction, validity and performance, and
that none of its terms or provisions may be waived, altered,
modified or amended except to the extent the Company may con-
sent thereto in writing.
          IN WITNESS WHEREOF, the Payor has executed and de-
livered this Note to the Company as of the date first above
written.

other rights granted under the Notes, to exercise all of the
rights and remedies with respect to the Collateral of a se-
cured party under the Uniform Commercial Code or any other ap-
plicable law, all of which rights and remedies, to the full
extent permitted by law, shall be cumulative and not alterna-
                               -5-

tive.  Pledgor agrees that 30 days shall constitute reasonable
notice of a sale or other disposition of any of the Colla-
teral.  The remainder of the proceeds from any such sale or
other disposition, after deducting therefrom all expenses in-
curred in connection therewith (including reasonable legal
fees and expenses) and after payment in full of Pledgor's ob-
ligations to the Company under the Notes and this Agreement,
shall be paid over to Pledgor.  The Company shall not sell or
otherwise dispose of a greater number of Shares that it rea-
sonably determines is necessary for the payment in full of
Pledgor's obligations to the Company under the Notes and this
Agreement, including all expenses incurred in connection with
such sale or other disposition.  Pledgor further agrees that a
private sale of the Collateral on such terms as the Company
approves shall be deemed to be commercially reasonable; PRO-
VIDED, HOWEVER, that the Company is authorized in its absolute
discretion to restrict the prospective purchasers to those
persons who represent and agree to the satisfaction of the
Company and its counsel that they are purchasing the Colla-
teral for their own account, for investment, and not with a 
view to or for sale in connection with a distribution in vio-
lation of the Securities Act of 1933 or any other applicable
law or regulation.
     5.  WAIVER OF RIGHTS OR REMEDIES.  (a)  The Company, by
act, delay, omission, acceptance of partial payment or other-
wise, shall not be deemed to have waived any rights or reme-
                               -6-

dies hereunder or under the Notes unless the waiver is in
writing and signed by the Company, and then only to the extent
therein set forth.  A waiver by the Company of any right or
remedy on any one occasion, shall not be construed as a bar to
or waiver of any such right or remedy, or both, that the Com-
pany otherwise would have had on any future occasion.
          (b)  To the full extent that Pledgor may lawfully so
agree, Pledgor agrees that it will not at any time plead,
claim or take the benefit of any moratorium or redemption law
now or hereafter enforced, in order to prevent or delay the
enforcement of this Agreement or the application of any por-
tion or all of the Collateral as provided by this Agreement, and
Pledgor, for himself and all who may claim under Pledgor, 
as far as they now or hereafter lawfully may, hereby waives
the benefit of all such laws.
     6.  AUTHORIZATION.  The Company shall have and be en-
titled to exercise all such powers hereunder as are specific-
ally delegated to the Company by the terms hereof, together
with such powers as are reasonably incidental thereto.  The
Company may execute any of its duties hereunder by or through
designees and shall be entitled to retain counsel and to act
in reliance upon the advise of such counsel concerning all
matters pertaining to its duties hereunder.  Neither the Com-
pany, nor any director, officer or employee of the Company,
shall be liable to Pledgor for any action taken or omitted to
                               -7-

be taken by it or them hereunder in connection herewith, ex-
cept for its or their own negligence or willful misconduct or
breach of this Agreement.  The Company shall be entitled to
rely on any communication, instrument or document believed by
it to be genuine and correct and to have been signed or sent
by the proper person or persons.
     7.   FURTHER ASSURANCES. Pledgor agrees that he shall at
the request of the Company execute and deliver all such fur-
ther assignments, endorsements and other documents and take
all such further action as the Company may reasonably request
in order to effect the purposes and provisions of this Agree-
ment and to perfect, continue, better assure or confirm the
rights of the Company in the Collateral provided for here-
under.
     8.  TERMINATION.  The security interest and assignment
created and granted hereunder shall terminate only when Pled-
gor has fully satisfied all of his obligations hereunder and
under the Notes, and at that time all Collateral remaining in
the possession of the Company shall be returned to Pledgor, 
accompanied by appropriate stock powers.
     9.  NOTICES.  Notices or other communications to either
of the parties shall be in writing and shall be deemed to have
been duly and properly given on the date such notices or other
communications are (i) personally delivered with receipt ac-
knowledged, or (ii) received when mailed by registered or cer-
tified mail, postage prepaid, return receipt requested, to the

          FOR VALUE RECEIVED, ROBERT ALVINE (the "Payor")
hereby promises to pay to CHARTER POWER SYSTEMS, INC., a Dela-
ware corporation ("the Company"), the principal sum of _______
____________________________________ ($__________), without in-
terest, in four equal annual installments on April 15 of each 
of 1990 through 1993.  Payment of principal is to be made in
lawful money of the United States of America at the offices of
the Company or at such other place as the holder hereof shall
designate.
     This Note is secured by the pledge by the Payor to
the Company of certain shares of common stock of the Company,
in accordance with the terms of a Pledge and Security Agree-
ment (the "Security Agreement") between the Payor and the Com-
pany, dated June ___, 1988, and in that respect is subject to
all of the terms, provisions and conditions of the Security
Agreement.
     This Note evidences a loan made by the Company to
the Payor to enable him to purchase 316,515 shares of common
stock of the Company (the "Shares").  If the Payor shall sell
or transfer any of his Shares or the proceeds thereof, or any

cash (other than cash dividends), securities, or other prop-
erty at any time and from time to time receivable or otherwise
distributed in respect of or in exchange for any or all of the
Shares (collectively, the "Additional Shares"), there shall be
due and payable, immediately upon the consummation of the sale
or transfer, a payment of principal hereunder in an amount
equal to the product obtained by multiplying the then out-
standing principal amount of this Note by a fraction, the nu-
merator of which shall be the number of Shares and Additional
Shares then sold or transferred and the denominator of which
shall be the number of Shares and Additional Shares then owned
by the Payor (before giving effect to the sale or transfer).
Nothing in this paragraph shall be deemed to permit any sale
or transfer by the Payor of any Shares or Additional Shares,
to the extent the same otherwise would be prohibited by the
provisions of any other agreement to which the Payor and the
Company are parties.
          If: (i) the Payor fails to make any payment
hereunder within ten days after notice from the Company to the
Payor that the payment is due; or (ii) the Payor's employment 
with the Company is terminated for "Cause", as defined in the
employment agreement, dated May 26, 1988, between the Payor
and the Company; or (iii) a Default (as is defined in the Se-
curity Agreement) shall have occurred under the Security
Agreement (each of the events listed in (i), (ii) and (iii)
                              -2-

above being an "Event of Default" hereunder); the then out-
standing principal balance hereof shall become immediately due
and payable.
          The Payor may, at any time and from time to time,
prepay in whole or part, without premium or penalty, the then
outstanding principal balance hereof.
          The Payor hereby agrees to pay all reasonable costs,
fees and expenses incurred by the Company for the collection
of all sums due hereunder, including reasonable attorneys'
fees and court costs.  The Payor hereby waives presentment, 
demand, notice of dishonor, protest and all other demands and
notices in connection with this Note (including any accelera-
tion of the maturity hereof) and further agrees that this Note
shall be deemed to have been made under and shall be governed
by the laws of the State of New York in all respects (without 
giving effect to the conflicts of law provisions thereof), in-
cluding matters of construction, validity and performance, and
that none of its terms or provisions may be waived, altered,
modified or amended except to the extent the Company may con-
sent thereto in writing.
          IN WITNESS WHEREOF, the Payor has executed and de-
livered this Note to the Company as of the date first above
written.

                         OPTION AGREEMENT

          ROBERT ALVINE (the "Optionee") hereby is granted the
 option (the "Option") to purchase Two Hundred Eleven Thousand 
 and Ten (211,010) fully paid and nonassessable shares of the
 common stock, par value $.01 per share (the "Common Stock"), 
 of Charter Power systems, Inc., a Delaware corporation (the
 "Company"), upon and subject to the following terms and condi-
 tions:
     1.   Option Price.  The price at which shares of Common
 Stock subject to the Option may be purchased is $6.04 a share.
     2.   Duration of Option.  The Option shall expire, and 
 all rights to purchase share of Common Stock pursuant thereto
 shall cease, on April 30, 1993 (the "Expiration Date").
     3.   Vesting of Option.  No portion of the Option may be
 exercised until it has vested.  The Option shall vest as set
 forth in Schedule 1 attached hereto.
     4.   Exercise of Options.  A person entitled to exercise
 the Option may exercise it in whole at any time, or in part
 from time to time, by delivering to the Company at its princi-
 pal office, directed to the attention of its Treasurer, (a)
 written notice specifying the number of share of Common Stock
 with respect to which the Option is being exercised, (b) pay-
 
 ment in full of the purchase price for those shares and (c)
 payment of the amount required for the Company to satisfy its
 withholding tax obligation respecting that exercise as deter-
 mined by the Company's independent accountants.  Those pay-
 ments shall be made in cash, by check to the order of the Com-
 pany or, in the case of a payment of the amount described in
 clause (b) above (less the par value of the relevant shares),
 by delivery of a Secured Promissory Note in the form attached
 as Exhibit A hereto.
     5.   Nontransferability.  The Option shall not be trans-
 ferable other than by will or the laws of descent and distri-
 bution and the Option may not be exercised by anyone other 
 than the Optionee, except that, if the Optionee dies or be-
 comes incapacitated, the Option may be exercised by the Op-
 tionee's estate, legal representative or beneficiary, as the
 case may be, subject to all other terms and conditions con-
 tained in this Agreement.
     6.   Termination of Employment.  The following rules 
 shall apply in the event of the termination of the Optionee's
 employment with the Company:
          (i) if the termination is for "Cause", as defined 
 in the employment agreement, dated the date hereof, be-
 tween the Optionee and the Company, the Option immedi-
 ately shall terminate;
 
                               -2- 
          

          (ii) if the termination is other than for Cause (in-   
cluding due to death or disability), the Option shall ex-
pire 18 months after the date of termination, or on the
applicable Expiration Date, whichever first shall occur;
and
          (iii) anything contained in this Section 6 to the
contrary notwithstanding, except as provided in part B of
Schedule 1 hereto, the Option may be exercised following
termination of the Optionee's employment only if, and to
the extent that, the Option was exercisable as of the 
date of termination.
     7.   No Rights as Stockholder or to Continued Employ-
 ment.  The Optionee shall not have any rights as a stockholder
 of the Company with respect to any shares covered by the Op-
 tion prior to the date of issuance to the Optionee of the cer-
 tificate or certificates for such shares, and the Option shall
 not confer upon the Optionee any right to continuance of em-
 ployment with the Company or any of its subsidiaries or inter-
 fere in any way with the right of the Company or of its sub-
 sidiaries to terminate the employment of the Optionee.
     8.   Issuance of Shares; Restrictions. (a) Subject to 
 the conditions and restrictions provided to this Section 8, 
 the Company shall, within 20 business days after the Option 
 has been duly exercised in whole or in part, deliver to the
 person who exercised the Option one or more certificates, reg-
                               -3-
 
 istered in the name of that person, for the number of shares 
 of Common Stock with respect to which the Option was exer-
 cised.  The Company may place a legend on any stock certifi-
 cate issued hereunder to reflect any restriction s provided for
 in this Section 8.
          (b)  Unless the issuance of the shares subject to 
 the Option has been registered under the securities Act of 
 1933 (the "Act") (and, if the Optionee may be deemed an "af-
 filiate" of the Company, as defined in Rule 405 under the Act,
 if the resale by the Optionee of those shares also has been
 registered under the Act), or the Company (based upon advice 
 of counsel) has determined that an exemption from registration
 under the Act is available, the Company may require prior to
 and as a condition of the issuance of any shares of Common
 Stock, that the person exercising the Option hereunder provide
 to the Company a written representation in a form prescribed 
 by the Committee to the effect that that person is acquiring
 those shares solely with a view to investment, for that per-
 son's own account, and not with a view to the resale or dis-
 tribution of all or any part thereof, and that such person 
 will not dispose of any of those shares other than in accord-
 ance with the registration provisions of the Act, unless the
 Company (based upon advice of counsel) is satisfied that an ex-
 emption from such registration is available.
                               -4-
                                  
          
        (c)  Anything contained herein to the contrary not-
withstanding, the Company shall not be obligated to issue any
shares of Common Stock upon the exercise of the Option granted
hereunder unless and until the Company is satisfied that such
issuance complies with all applicable provisions of the Act 
and all other applicable laws or regulations by which the Com-
pany is bound or to which the Company or those shares are sub-
ject.
     9.   Adjustments.  The number of shares of Common Stock
 covered by the Option and the exercise price therefor shall be
 adjusted proportionately for any increase or decrease in the
 number of outstanding shares of Common Stock resulting from a
 stock split or other subdivision or consolidation of shares or
 other capital adjustment, or the payment of a stock dividend;
 provided, however, that any fractional shares resulting from 
 any such adjustment shall be eliminated.  Notwithstanding the
 foregoing, no adjustment shall be made upon the issuance of 
 new shares of Common Stock for fair consideration.
     10.  Condition.  The Option is subject to the approval
 thereof by the holders of shares of Common Stock and to the
 listing on the American Stock Exchange of the shares of Common
 Stock issuable upon exercise of the Option (subject to notice 
 of issuance).
     11.  Miscellaneous.
          (a)  Notices.  All notices and other communications
 required or permitted to be given hereunder shall be in

                            Schedule 1

  A. Vesting of Option.
  
          The Option shall vest: (i) to the extent of 105,505
  shares as of January 31, 1990, only if the Company's earnings
  per share (the "EPS") for the fiscal year ending January 31,
  1990 equal or exceed $1.05; and (ii) to the extent of the re-
  maining 105,505 shares (the "Second Portion"), as of January
  31, 1991, only if the EPS for the fiscal year ending January
  31, 1991 equal to or exceed $1.25.  For this purpose, the EPS
  shall be as reported in the Company's audited financial state-
  ments for the relevant fiscal year, adjusted to exclude from
  the calculation of EPS (a) any extraordinary items (as deter-
  mined by the Company's independent accountants in accordance
  with generally accepted accounting principles), (b) any shares
  issued or issuable pursuant to the Company's Stock Option Plan
  and (c) any increase or decrease in the number of outstanding
  shares resulting from a stock split or other subdivision or
  consolidation of shares or other capital adjustment, or the
  payment of a stock dividend.
          If the employment of the Optionee with the Company 
  is terminated due to death or disability (as defined in the
  employment agreement, dated the date hereof, between the Op-
  tionee and the Company (the "Employment Agreement")) after
  October 31, 1989 or 1990 and the applicable EPS amount for the
  
  
                                (i)

fiscal year ending January 31, 1990 or 1991, as the case may
 be, is met, the Optionee shall be deemed to have been employed
  through the end of the relevant fiscal year for the purpose of
  the vesting of the Option.
  B. Accelerated Vesting.
          The Option (if (i) the circumstance or transaction
  described in paragraph 1 or 2(a) below occurs or is completed
  on or before January 31, 1991 or (ii) the transaction de-
  scribed in paragraph 2(b) below is completed on or before
  January 31, 1990) or the Second Portion (if the transaction
  described in paragraph 2(b) below occurs or is completed after
  January 31, 1990 and on or before January 31, 1991) shall vest
  on an accelerated basis to the extent provided below:
     1.   If the average of the daily closing prices of the
  Common Stock of the Company, as reported by the American Stock
  Exchange (the "AMEX"), during any 60-day period equals or
  exceeds $15.00 a share, full accelerated vesting shall occur on
  the last day of that 60-day period.
     2.   If: (a) a Business Combination (as defined in the
  Employment Agreement) has occurred at a weighted average price
  per share on a fully diluted basis (the "Transaction Price") of
  not less than $11.00; or (b) a Change of Control (as de-
  fined in the Employment Agreement) other than a Business Com-
  bination has occurred and the average of the daily closing

          This Note is secured by the pledge by the Payor to
  the Company of certain shares of common stock of the Company,
  in accordance with the terms of a Pledge and Security Agree-
  ment (the "Security Agreement") between the Payor and the Com-

  This Note evidences a loan made by the Company to 
  the Payor to enable him to purchase _______*** shares of common
  stock of the Company (the "Shares").  If the Payor shall sell

  equal to the product obtained by multiplying the then out-
  standing principal amount of this Note by a fraction, the nu-
  merator of which shall be the number of Shares and Additional
  Shares then sold or transferred and the denominator of which
  shall be the number of Shares and Additional Shares then owned
  by the Payor (before giving effect to the sale or transfer). 
  Nothing in this paragraph shall be deemed to permit any sale

                  REGISTRATION RIGHTS AGREEMENT

          AGREEMENT, dated May 26, 1988, between ROBERT ALVINE
(the "Shareholder") and CHARTER POWER SYSTEMS, INC., a Dela-
ware corporation (the "Company").

          WHEREAS, the Shareholder on the date hereof has
agreed to purchase 316,515 shares of Common Stock, $.01 par
value, of the Company ("Common Stock") and has been granted
the option to purchase an additional 211,010 shares of Common
Stock (all such shares hereinafter are referred to
collectively as the "Shares");

          WHEREAS, the Company has agreed to provide the
Shareholder with certain registration rights respecting the
Shares.

          NOW, THEREFORE, in consideration of the foregoing
and of the mutual covenants and agreements set forth herein,
the parties hereto agree as follows:

          1.  DEMAND REGISTRATION.  During each of the fol-
lowing periods: (a) the 18-month period following the termina-
tion of the employment of the Shareholder with the Company
without "Cause" (as defined in the Employment Agreement, of
even date herewith, between the Company and the Shareholder);
or (b) at any time after April 30, 1991, so long as the Share-
holder is employed by the Company at that time; the Share-
holder shall be entitled to request, and the Company thereupon
shall diligently effect in accordance with the terms hereof,
one registration under the Securities Act of 1933 (the "Act")
of all or any portion of his Shares owned at the time of the
request, in the case of clause (a) above, or up to 50% of such
Shares, in the case of clause (b) above, in which the Company
shall pay all Registration Expenses (as defined in Section 6
hereof) (the "Demand Registrations").  A registration will not 
be deemed a Demand Registration permitted pursuant to this
Section 1 unless it has become effective and the Shareholder
is legally permitted to sell the Shares that are requested and
required to be included in that registration and the Company
has complied with the other applicable provisions of this
Agreement.

          2.  NO-SALE AGREEMENT.  The obligation of the Com-
pany to include Shares in the Demand Registrations as provided
in Section 1 hereof shall be subject to the Company's receipt 
from the Shareholder of a written agreement not to effect any

public sale or distribution (other than through the registered
public offering) of equity securities of the Company during
the ten days prior to and the 90-day period beginning on the 
effective date of that registration or, if sooner, until all
Shares and other securities included in that registration have
been sold.

          3.  EFFECTING THE REGISTRATION.  Whenever the Share-
holder requests that any Shares be registered pursuant to the
provisions of this Agreement, the Company shall use its best
efforts to effect the registration and the sale of those
Shares in accordance with the intended method of disposition
thereof and, pursuant thereto, the Company shall, as expedi-
tiously as possible:

               (a)  prepare and file with the Securities and
Exchange Commission (subject to its receipt from the Share-
holder of the written information specified in Section 7(b) 
hereof) a registration statement with respect to those Shares,
which registration statement shall state that the Shareholder
may sell those Shares either under that registration statement
or (to the extent available to the Shareholder) pursuant to
Rule 144 (or any similar rule then in effect), and shall use
its best efforts to cause such registration statement to be-
come effective;

               (b)  prepare and file with the Securities and
Exchange Commission (subject to its receipt from the Share-
holder of the written information specified in Section 7(b)
hereof) such amendments and supplements to that registration
statement and the prospectus used in connection therewith as
may be necessary to keep that registration statement effective
for a period of not less than six months and comply with the
provisions of the Act with respect to the disposition of all
securities covered by that registration statement during that
six-month period in accordance with the intended method of
disposition by the Shareholder set forth in that registration
statement;

               (c)  provide to the Shareholder such number of
copies of that registration statement, each amendment and sup-
plement thereto, the prospectus included in such registration
statement (including each preliminary prospectus) and such
other documents as the Shareholder reasonably may request in
order to facilitate the disposition of the Shares owned by the
Shareholder included in that registration statement;

               (d)  use its best efforts to register or qualify
those Shares under the securities or blue-sky laws of such
jurisdictions as the Shareholder reasonably requests and do 
any and all other acts and things that may be reasonably

                               -2-

necessary or advisable to enable the Shareholder to consummate
the disposition in those jurisdictions of the Shares owned by
the Shareholder included in that registration statement (PRO-
VIDED, HOWEVER, that the Company shall not be required, in
order to complete that registration or qualification, to (i)
qualify generally to do business in any such jurisdiction 
where it otherwise would not be required to qualify but for
this subparagraph, (ii) subject itself to taxation in any such
jurisdiction, (iii) consent to general service of process in
any such jurisdiction (it being agreed that the Company shall
be obligated, to the extent required in any applicable juris-
diction, to consent to limited service of process with respect
to matters relating to the offering being so registered or
qualified), or (iv) otherwise subject itself or any of its af-
filiates to unreasonable expense or restrictions);

               (e)  notify the Shareholder, at any time when a
prospectus relating thereto is required to be delivered under
the Act, of the happening of any event or the discovery of any 
information, as a result of which the prospectus included in
that registration statement contains any statement which, at
the time and in light of the circumstances under which it was
made, is false or misleading with respect to any material fact
or omits to state a material fact required to be stated
therein or necessary in order to make the statement therein
not false or misleading, and, at the request of the Share-
holder, the Company shall prepare a supplement or amendment to
that prospectus so that, as thereafter delivered to the pur-
chasers of those Shares, that prospectus will not contain any
statement which, at the time and in light of the circumstances
under which it was made, is false or misleading with respect
to any material fact or omits to state a material fact re-
quired to be stated therein or necessary in order to make the
statements therein not false or misleading;

               (f)  enter into such customary agreements (in-
cluding an underwriting agreement in customary form and on
terms reasonably agreeable to it) and take all such other ac-
tions as the holders of a majority of the securities covered
by the registration statement or the underwriters, if any,
reasonably request in order to expedite or facilitate the dis-
position of those securities; and

               (g)  make available for inspection by the Share-
holder, any underwriter participating in any disposition pur-
suant to the registration statement, and any attorney, ac-
countant or other agent retained by the Shareholder or that
underwriter, all financial and other records, pertinent corpo-
rate documents and properties of the Company, and cause the
Company's officers, directors and employees to supply all in-

                               -3-

formation reasonably requested by the Shareholder or that un-
derwriter, attorney, accountant or agent in connection with
that registration statement.

Notwithstanding anything contained in this Section 3 to the
contrary, the Company shall not be required to file any regis-
tration statement pursuant to Section 1 hereof; (i) until it 
has filed its Form 10-Q (or its then equivalent) for its most
recently completed fiscal quarter (unless the Company meets
the eligibility requirements for the use of a registration
statement on Form S-2) and its Form 10-K for its most recently
completed fiscal year; or (ii) during any period of time when
(A) the Company is contemplating an underwritten public offer-
ing of any of its securities within three months and, in the
judgement of the managing or principal underwriter thereof or
of the Company, that filing would have an adverse effect on
the contemplated offering, (B) the Company is in possession of
material nonpublic information (notice of which shall have 
been given by the Company to the Shareholder) that it deems in
its legitimate business interest not to disclose in a regis-
tration statement or (C) the Company is engaged in any program
for the purchase of shares of its Common Stock; PROVIDED, HOW-
EVER, that the aggregate of the periods in this clause (ii) 
shall not exceed 120 days during the 18-month period provided 
in Section 1(a) hereof).

          4.  OPINION OF COUNSEL AND LETTER FROM ACCOUNTANTS.
If and whenever the Company is required by the provisions of 
this Agreement to use its best efforts to effect the registra-
tion of Shares under the Act, the Company shall provide, at
the request of the Shareholder, on the date that those Shares
are delivered to the underwriters for sale pursuant to that
registration or, if those Shares are not being sold through
underwriters, on the date the registration statement with re-
spect to those Shares becomes effective: (a) an opinion, dated
such date, of the independent counsel representing the Company 
for the purposes of such registration, addressed to the under-
writers, if any, and to the Shareholder, to the effect that
(i) the registration statement, the related prospectus and
each amendment or supplement thereto, comply as to form in all
material respects with the requirements of the Act and the ap-
plicable rules and regulations of the Securities and Exchange
Commission thereunder (except that such counsel need express
no opinion as to the financial statements and schedules and
other financial and statistical data contained therein), (ii)
while such counsel is not passing upon and does not assume any
responsibility for the accuracy, completeness or fairness of
the statements contained in the registration statement and the
prospectus (except for the matters referred to in clause (iii)
below), such counsel has no reason to believe either that the
registration statement or the prospectus (and any amendment or
supplement thereto), at the time that registration statement
became effective (or in the case of an amendment or supple-

                               -4-

ment, at the time it was filed), and with respect to the pros-
pectus, on the date of such prospectus, contains any statement
which, at the time and in light of the circumstances under
which it was made, is false or misleading with respect to any
material fact or omits to state a material fact required to be
stated therein or necessary in order to make the statements
therein not false or misleading (except that such counsel need
express no opinion as to the financial statements and sched-
ules and other financial and statistical data, or the informa-
tion provided by the Shareholder pursuant to Section 7(b)
hereof, contained therein), and (iii) all of the Shares in-
cluded in the registration statement have been duly authorized
and validly issued, and are fully paid and nonassessable; and
(b) a letter, dated that date, from the independent certified
public accountants of the Company, addressed to the under-
writers, if any, and to the Shareholder, if he would be deemed
an affiliate of the Company as defined in Rule 405 under the
Act, stating (i) that they are independent certified public
accountants within the meaning of the Act and that in the
opinion of such accountants, the financial statements and
schedules of the Company included in the registration state-
ment or the prospectus, or any amendment or supplement there-
to, comply as to form in all material respects with the appli-
cable accounting requirements of the Act, and (ii) such other
financial matters (including information as to the period end-
ing not more than five business days prior to the date of such 
letter) with respect to the registration statement as the un-
derwriters, if any, or the Shareholder, if he would qualify as
an underwriter, may reasonably request; PROVIDED, HOWEVER,
that the Company shall not be considered to be in breach of
this Section 4 if its independent certified public accountants
or counsel shall have refused to deliver all or any part of
the letter or opinion specified in this Section 4 without
qualification or limitation (other than standard qualifica-
tions and limitations) not specified above, if the Company
shall have requested such accountants or counsel to provide
the same and shall have cooperated in all reasonable respects,
to the extent requested by such accountants or counsel, in
providing them with information required for the preparation
of that letter or opinion.

          5.  REVIEW BY THE SHAREHOLDER.  No less than five
business days prior to the filing of a registration statement
or prospectus, or any amendment or supplement thereto, the
Company shall provide the Shareholder with a substantially
final copy of such proposed registration statement, pros-
pectus, amendment or supplement.  If, prior to that filing,
the Company shall receive written notice from the Shareholder
to the effect that that registration statement, prospectus,
amendment or supplement contains any statement relating to the
Shareholder which is false or misleading or omits to state a
material fact, then the Company shall not file that registra-
tion statement, prospectus, amendment or supplement without

                               -5-

the prior written consent of the Shareholder, which consent
shall not be unreasonably withheld.

          6.  EXPENSES.  All expenses incident to the Com-
pany's performance of or compliance with the registration ob-
ligations set forth in this Agreement, including all registra-
tion and filing fees, expenses of compliance with securities
or blue-sky laws, printing expenses, messenger and delivery
expenses, and fees and disbursements of counsel for the Com-
pany (but not counsel for the Shareholder) and all independent
certified public accountants, underwriters (excluding dis-
counts and commissions) and other persons retained by the Com-
pany (all such expenses being herein called "Registration Ex-
penses"), shall be borne by the Company.

          7.  INDEMNIFICATION.  (a)  The Company shall indem-
nify, to the extent permitted by law, the Shareholder and any
underwriter (and any controlling person thereof) acting on
his behalf, against all losses, claims, damages, liabilities
and expenses (including reasonable attorneys' fees and dis-
bursements) resulting from any untrue or alleged untrue state-
ment of material fact contained in any registration statement,
prospectus or preliminary prospectus, or any amendment or sup-
plement thereto, or any omission or alleged omission to state
therein a material fact required to be stated therein or ne-
cessary to make the statements therein not misleading, except
insofar as the same are caused by or contained in any informa-
tion provided in writing to the Company by the Shareholder ex-
pressly for use therein or by the Shareholder's or such under-
writers' failure to deliver a copy of the registration state-
ment or prospectus or any amendments or supplements thereto
after the Company has provided the Shareholder or such under-
writer with a sufficient number of copies of the same.

               (b)  In connection with any registration state-
ment or amendment thereto in which the Shareholder is partici-
pating pursuant to the provisions of this Agreement, the
Shareholder shall provide the Company in writing with such in-
formation and affidavits as the Company reasonably shall re-
quest for use in connection with any such registration state-
ment or amendment and, to the extent permitted by law, shall
indemnify the Company, its directors and officers, each person
who controls the Company within the meaning of Section 15 of
the Act or Section 20(a) of the Exchange Act of 1934 (the "Ex-
change Act") and any underwriter (and any controlling person
thereof) acting on the Company's behalf against any losses,
claims, damages, liabilities and expenses (including reason-
able attorneys' fees and disbursements) resulting from any un-
true or alleged untrue statement of material fact or any omis-
sion or alleged omission of a material fact required to be
stated in the registration statement or any amendment thereof

                               -6-

or supplement thereto or necessary to make the statements
therein not misleading, but only to the extent that such un-
true statement or omission is contained in (or should have
been contained in, but was omitted from) any information or
affidavit so provided in writing by the Shareholder.

               (c)  Any person entitled to indemnification
hereunder shall (i) give prompt notice to the indemnifying 
party of any claim with respect to which the indemnified party
seeks indemnification and (ii) unless in the indemnified
party's reasonable judgement a conflict of interest between the
indemnified and indemnifying parties may exist with respect to
such claim, permit such indemnifying party to assume the de-
fense of such claim with counsel reasonably satisfactory to
the indemnified part.  If such defense is assumed, the indem-
nifying party shall be entitled in its sole discretion to set-
tle such claim at no cost to the indemnified party.  An indem-
nifying party who is not entitled to, or elects not to, assume
the defense of a claim shall not be obligated to pay the fees
and expenses of more than one counsel for all parties indemni-
fied by such indemnifying party with respect to such claim,
unless in the reasonable judgment of any indemnified party a
conflict of interest may exist between such indemnified party 
and any other indemnified party with respect to such claim.
Notwithstanding the foregoing, any indemnified party shall
have the right, in any action the defense of which has been
assumed by the indemnifying party, to employ separate counsel
and to participate in the defense of such action, but the fees
and expenses of such counsel (except those, if any, incurred
before the defense was assumed by the indemnifying party)
shall be the responsibility of the indemnified party.

          8.  PARTICIPATION IN UNDERWRITTEN REGISTRATIONS.
The Shareholder may not participate in any underwritten regis-
tration pursuant to the provisions of this Agreement unless he
(i) agrees to sell his Shares on the basis provided in any un-
derwriting arrangements approved by the person entitled here-
under to approve such arrangements and (ii) completes and ex-
ecutes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents required under the
terms of such underwriting arrangements.

          9.  SELECTION OF UNDERWRITERS.  If any registration
pursuant hereto is an underwritten offering, the Company will
have the right to reasonably approve the investment banker(s)
and manager(s) selected by the Shareholder to administer the
offering.

          10.  COVENANTS OF THE COMPANY.  The Company shall
use its best efforts to file in a timely manner all reports
required to be filed by it pursuant to the Exchange Act and,
upon request of the Shareholder, shall provide the Shareholder

                               -7-

with such information as may be necessary to enable the
Shareholder to effect routine sales pursuant to Rule 144 under
the Act.

          11.  MISCELLANEOUS.  (a) NOTICES.  All notices and
other communications required or permitted to be given under
this Agreement shall be in writing and shall be deemed to have

               (b)  BINDING EFFECT; BENEFITS.  This Agreement
shall be binding upon and inure to the benefit of the parties
to this Agreement, and the successors and assigns of the Com-
pany, on the one hand, and any other person which acquires any
Shares from the Shareholder in a transaction that is exempt
from the registration and prospectus delivery requirements of
the Act and has given written notice to the Company of its ac-
quisition of these Shares, on the other hand.  Nothing in this
Agreement, expressed or implied, is intended or shall be con-
strued to give any other person any legal or equitable right,
remedy or claim under or in respect of any agreement or any
provision contained herein.  Except as provided in this sub-
section (b), neither this Agreement nor any right, remedy, ob-
ligation or liability arising hereunder or by reason hereof
shall be assignable by the Shareholder without the prior
written consent of the Company.

               (c)  WAIVER, AMENDMENT.

of any of the obligations or other actions of any other party
to it under this Agreement, (b) waive complaince with any of
the conditions or covenants of any other party to it contained
in this Agreement, and (c) waive or modify performance of any
of the obligations of any other party to it under this Agree-
ment.  Except as provided in the preceding sentence, no action
taken pursuant to this Agreement, including, without limita-
tion, any investigation by or on behalf of any party, shall be
deemed to constitute a waiver by the party taking such action
of compliance with any representations, warranties, covenants
or agreements contained herein.  The waiver by any party here-
to of a breach of any provision of the Agreement shall not

                               -8-

operate or be construed as a waiver of any preceding or suc-
ceeding breach and no failure by any party to exercise any
right or privilege hereunder shall be deemed a waiver of such
party's rights or privileges hereunder or shall be deemed a
waiver of such party's rights to exercise the same at any sub-
sequent time or times hereunder.

                    (ii) AMENDMENT.  This Agreement may be amend-
ed, modified or supplemented only by a written instrument exe-
cuted by the Shareholder and the Company.

               (d)  APPLICABLE LAW.  This Agreement shall be
governed as to its validity, interpretation and effect and
constured in accordance with the laws of the State of New
York, regardless of the law that might be applied under the
principles of conflicts of law.

               (e)  COUNTERPARTS.  This Agreement and any amend-
ments, waivers, consents or supplements hereto may be executed
in any number of counterparts, each of which when so executed
shall be deemed to be an original, but all of which counter-
parts when taken together shall constitute one and the same
instrument.

               (f)  ENTIRE AGREEMENT.  This Agreement constitu-
tutes the entire agreement and supersedes all prior agreements
and understandings, both written and oral, among the parties
with respect to the subject matter hereof.

               (g)  ADJUSTMENTS AFFECTING SECURITIES.  The term
"Shares" as used herein shall include all additional equity
securities issued with respect thereto pursuant to any subse-
quent stock split, stock dividend, recapitalization, merger,
consolidation or other reorganization affecting the number of
outstanding shares of Common Stock.

               (h)  SEVERABILITY.  If any provision of this
Agreement is unenforceable for any reason, the remaining pro-
visions hereof shall not be effected thereby and shall never-
theless remain in full force and effect.

     IN WITNESS WHEREOF, the parties have executed this Agree-
ment on the date first written above.

immediately preceding the month in which the Base Salary

adjustment shall occur and (ii) the denominator of which
shall be the Index for the month immediately preceding the
month in which the immediately preceding term commenced (or,

                            SCHEDULE 1

A.   VESTING OF OPTION.
          The Option shall vest:  (i) to the extent of
105,505 shares (the "First Portion"), as of January 31, 1990,
only if the Company's earnings per share (the "EPS") for the
fiscal year ending January 31, 1990 equal or exceed $1.05;
and (ii) to the extent of the remaining 105,505 shares (the
"Second Portion"), as of January 31, 1991, only if the EPS
for the fiscal year ending January 31, 1991 equal or exceed
$1.25.  For this purpose, the EPS shall be as reported in the
Company's audited financial statements for the relevant
fiscal year, adjusted to exclude from the calculation of EPS
(a) any extraordinary items (as determined by the Company's
independent accountants in accordance with generally accepted
accounting principles), (b) any shares issued or issuable
pursuant to the Company's Stock Option Plan and (c) any
increase or decrease in the number of outstanding shares
resulting from a stock split or other subdivision or
consolidation of shares or other capital adjustment, or the
payment of a stock dividend.
          If the employment of the Optionee with the Company
is terminated due to death or disability (as defined in the
employment agreement, dated the date hereof, between the
Optionee and the Company (the "Employment Agreement") after
                                1

October 31, 1989 or 1990 and the applicable EPS amount for
the fiscal year ending January 31, 1990 or 1991, as the case
may be, is met, the Optionee shall be deemed to have been
employed through the end of the relevant fiscal year for the
purpose of the vesting of the Option.
B.   ALTERNATIVE VESTING.
          The Option (if (i) the circumstance or transaction
described in paragraph 1 or 2(a) below occurs or is completed
on or before January 31, 1992 or (ii) the transaction
described in paragraph 2(b) below is completed on or before
January 31, 1991) or the Second Portion (if the transaction
described in paragraph 2(b) below occurs or is completed
after January 31, 1991 and on or before January 31, 1992)
shall vest on an accelerated basis to the extent provided
below:
          1.   If the average of the daily closing prices of
the Common Stock of the Company, as reported by the American
Stock Exchange (the "AMEX"), during any 60-day period equals
or exceeds $15.00 a share, full alternative vesting shall
occur on the last day of that 60-day period.
          2.   If:  (a) a Business Combination (as defined in
the Employment Agreement) has occurred at a weighted average
price per share on a fully diluted basis (the "Transaction
Price") of not less than $11.00; or (b) a Change of Control
(as defined in the Employment Agreement) other than a 
                                2

Business Combination has occurred and the average of the
daily closing prices of a share of the Common Stock of the
Company, as reported by the AMEX, during the 20 trading days
prior thereto (the "CC Price"), is not less than $11.00,
alternative vesting to the extent of the percentage specified
below shall occur upon consummation of the transaction:
          Transaction Price             Percentage of Unvested
             or CC Price                     Option to Vest

           $11.00 - $11.99                         20%
           $12.00 - $12.99                         40%
           $13.00 - $13.99                         60%
           $14.00 - $14.99                         80%
           $15.00 or greater                      100%
PROVIDED, HOWEVER, that notwithstanding the foregoing, with
respect to the First Portion, if the Change in Control shall
occur during the period from February 1, 1990 through January
31, 1991 (it being agreed that alternative vesting shall
occur with respect to the Second Portion to the extent, if
any, hereinabove provided without regard to this proviso if
the Change in Control shall occur during that period), and
with respect to the Second Portion, if the Change in Control
shall occur during the period from February 1, 1991 through
January 31, 1992 (it being agreed that alternative vesting
shall not occur with respect to the First Portion on account
of a Change in Control that occurs during that period),
alternative vesting shall occur only if the CC Price is not
less than $12.00 (but the percentage of alternative vesting
if the CC Price is from $12.00 - $12.99 shall remain 40%).
