                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1997

(1)  BASIS OF PRESENTATION
The accompanying interim financial statements have been prepared in accordance
with generally accepted accounting principles for interim financial information
and in conjunction with the rules and regulations of the Securities and Exchange
Commission.  Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements.  The interim financial statements include all adjustments
that, in the opinion of management, are necessary in order to make the financial
statements not misleading.  The amounts indicated as "audited" have been
extracted from the Company's December 31, 1996 annual report.  For further
information, refer to the consolidated financial statements and footnotes
included in PC Quote's annual report on Form 10-K for the year ended December
31, 1996.  Certain reclassifications have been made to conform to the current
presentation.

Costs associated with the planning and designing phase of software development,
including coding and testing activities necessary to establish technological
feasibility of computer software products to be sold, leased or otherwise
marketed, are charged to research and development costs as incurred.  Once
technological feasibility has been determined, costs incurred in the
construction phase of software development, including coding, testing and
product quality assurance, are capitalized.

Amortization is provided over an estimated life of the software products and
commences when the product is available for general release to customers. 
Unamortized capitalized costs determined to be in excess of the net realizable
value of the product are expensed at the date of such determination. The 
anticipated future gross revenues and remaining economic life of the products
are based on estimates which are subject to change.  Accumulated amortization
and related software development costs are removed in the year following full
amortization.

(2)  INCOME TAXES
At December 31, 1996, the Company had federal income tax net operating loss
carryforwards of approximately $12,059,000 for federal income tax purposes and
approximately $9,794,000 for alternative minimum tax purposes.  The net
operating loss carryforwards will expire in the years 1999 to 2011.

restructuring of operations. As a result, the Company wrote off approximately
$572,000 representing the unamortized portion of previously capitalized software
development costs. The write-off relates to development efforts which new
management has decided for economic reasons not to pursue. The management
reorganization resulted in the Company incurring employment termination costs of
$425,000 and $150,000 was paid to terminate a contractual arrangement related to
unprofitable operations.

(4)  BORROWINGS FROM SHAREHOLDER
On May 5, 1997, the Company and PICO Holdings, Inc. ("Holdings") entered into a
Loan and Security Agreement (the "Loan Agreement"), under which Holdings agreed
to make a secured loan to the Company in an aggregate principal amount of up to
$1.0 million at a fixed rate equal to 14% per annum. Unless otherwise extended,
the entire principal balance and all accrued interest due under the Loan
Agreement were payable on September 30, 1997. All advances under the Loan
Agreement are secured by a pledge of substantially all of the assets of the
Company. These liens are subject to the prior lien of the Company's primary
lender, Lakeside Bank. Holdings will be paid a "facility fee" of $40,000, plus
interest at a rate equal to 14% per annum, on the maturity date of the loan
contemplated by the Loan Agreement.

Also on May 5, 1997, in consideration of the loan by Holdings to the Company,
the Company issued a Common Stock Purchase Warrant (the "Warrant") to Holdings
entitling Holdings to purchase a minimum of 640,000 shares of the Company's
Common Stock at a price per share equal to the lesser of (a) the mean of the
closing bid price per share for the 20 trading days preceding exercise of the
Warrant or (b) $1.5625 per share (the market value of the Company's Common Stock
on the date the Warrant was issued). The Warrant expires on April 30, 2000.

In August 1997, the Company and Holdings agreed to amend the Loan Agreement and
related documents to increase the amount of the secured loan from Holdings to
the Company from $1.0 million up to $2.0 million. In connection with the
increase of the loan amount pursuant to such amendment, the Company granted
Holdings an additional Common Stock Purchase Warrant for a minimum of 500,000
shares of the Company's Common Stock. The terms of the additional warrant are
substantially the same as those contained in the Warrant, except that the
conversion price is the lesser of (a) $2.00 per share or (b) the mean of the
closing bid price per share for the 20 trading days preceding exercise of the
additional warrant.

<PAGE>

On September 22, 1997 the Company and Holdings executed a second amendment to
the Loan Agreement to further increase the amount of the secured loan from
Holdings to the Company from $2.0 million to $2.25 million. The terms of the
Loan Agreement otherwise remained substantially the same, except that the
maturity date was extended to December 31, 1997. In consideration of the
amendment to the Loan Agreement, the Company granted Holdings another Common
Stock Purchase Warrant for up to 129,032 shares of Common Stock. The terms of
such warrant are substantially the same as contained in the Warrant, except that
the conversion price is the lesser of (a) $1.9375 per share or (b) the mean of
the closing bid price per share for the 20 trading days preceding exercise of
this warrant 

(5)  SUBSEQUENT EVENTS
On October 22, 1997, pursuant to shareholder approval on October 16, 1997, a
Certificate of Amendment to the Company's Certificate of Incorporation that
increased the Company's total authorized Common Stock to fifty million
(50,000,000) shares, eliminated the Preferred Stock, par value $1.312704617 per
share, from the Company's authorized capital, and authorized the Company to
issue up to five million (5,000,000) shares of preferred stock, par value $0.001
per share, was filed with the Secretary of State of the State of Delaware. 

In October 1997 Imprimis Investors LLC and Wexford Spectrum Investors LLC
(collectively, the "Wexford Affiliates") expended $5.0 million to purchase five
million shares of Common Stock and warrants to purchase five hundred thousand
shares of Common Stock at an exercise price of $2.00 per share, exercisable at
any time prior to October 15, 2002 (the "Initial Warrants").

The Wexford Affiliates have acquired the Common Stock and the Warrants for
investment purposes pursuant to a certain Stock and Warrant Purchase Agreement
dated October 15, 1997, between PC Quote and the Wexford Affiliates (the
"Purchase Agreement").  Pursuant to the terms of the Purchase Agreement, on
October 15, 1997, the Wexford Affiliates purchased 1,450,000 shares of Common
Stock and the Initial Warrants for a purchase price of $1.45 million. On
October 20, 1997, pursuant to the terms of the Purchase Agreement, the Wexford
Affiliates purchased an additional 550,000 shares of Common Stock for a purchase
price of $0.55 million.  On October 23, 1997, pursuant to the terms of the
Purchase Agreement, the Wexford Affiliates purchased an additional 3,000,000
shares of Common Stock for a purchase price of $3.0 million.

                                     Page 9
<PAGE>

Up to four million of the shares of Common Stock purchased by the Wexford
Affiliates are subject to repurchase by PC Quote at a purchase price of $1.00
per share pursuant to the terms of the Purchase Agreement (the "Repurchase"). 
Pursuant to the terms of the Purchase Agreement, PC Quote will use its best
efforts to consummate the Repurchase from the proceeds of a rights offering.  In
the event that the rights offering is not completed on or prior to January 24,
1998, the Wexford Affiliates will be entitled to receive, out of escrow,
warrants to purchase an additional 250,000 shares of Common Stock with the same
terms as the Initial Warrants and, in the event the rights offering is not
completed on or prior to February 28, 1998, the Wexford Affiliates will be
entitled to receive, out of escrow, warrants to purchase an additional 250,000
shares of Common Stock with the same terms as the Initial Warrants.  

In contemplation of the Purchase Agreement, the Wexford Affiliates have agreed
not to participate in the rights offering. On October 31, 1997 a Form S-2
Registration Statement was filed with the Securities and Exchange Commission for
the rights offering.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 RESULTS OF OPERATIONS AND FINANCIAL CONDITION

INTRODUCTION

The statements made herein that are not historical facts may contain
forward-looking information that involve substantial risks and uncertainties.
The Company's actual results, performance or achievements could differ
materially from the results, performance or achievements expressed in, or
implied by, these forward-looking statements.  Among the factors that could
cause or contribute to such differences include the Company's ability to (i)
obtain adequate financing to fund its current and future business strategies,
(ii) attract and retain key employees, (iii) compete successfully against
competitive products and services, (iv) maintain its relationships with key
suppliers and providers of market data, (v) pay, refinance, or extend the up to
$2.25 million loan from PICO Holdings on or before December 31, 1997, and (vi)
the effect of economic and business conditions, generally.



RESULTS OF OPERATIONS:

FOR THE NINE MONTHS AND QUARTER ENDED SEPTEMBER 30, 1997

Service revenue for the nine months ended September 30,1997 decreased 2% from
the same period of 1996 and was essentially unchanged for the quarter ended
September 30, 1997 when compared to the same period of the prior year. The
decrease is due to the loss of two major customers in the Company's traditional
direct data feed business.  The lost revenue, $3.8 million and $400,000 for the
nine months and quarter, respectively, has been substantially offset by
increases in service revenue in the Company's traditional and internet
businesses, as well as revenue from the sale of advertising on the internet.

Direct costs of services increased 46% and 23% for the nine months and quarters
ended September 30, 1997, respectively, over the same periods in 1996. Principal
components of these increases were royalties, leased equipment, communication
costs, and compensation directly attributable to internet operations and sales
of PCW6.0, payments to providers of market data, and maintenance of and
enhancements to the Company's traditional direct data feed systems.

                                    Page 11  
<PAGE>

Amortization of software development for the nine months and quarter ended
September 30, 1997 increased 56% and 36%, respectively, from the same periods of
the prior year, reflecting the investment in internet and direct data feed
products and delivery mechanisms.

Similarly, research and development costs increased 65% and 73%, respectively,
for the nine months and quarter ended September 30, 1997 as compared to the same
periods in 1996. The increase was due to additional charges for equipment leased
to upgrade systems' design and testing equipment, in addition to costs of
maintaining and enhancing previously developed products and services.

Selling and marketing costs increased 23% and 2%, respectively, for the nine
months and quarter ended September 30, 1997 over the same periods in 1996. The
increase was mainly due to commissions. 

General and administrative expenses decreased 1% and 42% for the nine months and
the quarter ended September  30, 1997, respectively, from the same periods in
1996.  The decreases were principally due to reductions in compensation and
related employee costs and a decrease in bad debt expense for the quarter as
compared to the prior year.

In June 1997, the Company underwent a significant management reorganization and
restructuring of operations.  As a result, for the nine months ended September
30, 1997 the Company wrote off approximately $572,000 of unamortized software
development costs for previously capitalized software projects that were
discontinued.  The management reorganization resulted in the Company incurring
employment related termination costs of $425,000 and $150,000 was paid to
terminate a contractual arrangement related to unprofitable operations.

Interest expense increased 1,150% and 1,681%, respectively, for the nine months
and quarter ended September 30. 1997 over the same periods in 1996. The
increases reflect the recognition of non-cash amortization of $467,016 and
$330,936 for the nine months and quarter, respectively, for the value of the
$2.5 million convertible subordinated debenture's beneficial conversion feature
and amortization of $442,640 and $264,810 for the nine months and quarter,
respectively, for the value of the common stock purchase warrants issued to PICO
Holdings, Inc. in connection with a financing arrangement.  Also included is
interest on the bank term loan, the convertible subordinated debenture and
financing arrangement borrowings. See footnote 4 of the Notes to the Financial
Statements for additional information with respect to the financing arrangement.

                     MANAGEMENT'S DISCUSSIONS AND ANALYSIS OF
            RESULTS OF OPERATIONS AND FINANCIAL CONDITION (CONTINUED)

LIQUIDITY AND CAPITAL RESOURCES:

FOR THE NINE MONTHS AND QUARTER ENDED SEPTEMBER 30, 1997

Net cash declined by 93% for the nine months ended September 30, 1997 as
compared to 89% for the nine months ended September 30, 1996. Expenditures for
new equipment and capitalized software costs were 39% lower than last year.  New
direct borrowings of $2,290,000 from the 1997 loan facility with PICO Holdings,
discussed below, were also incurred.  Agreements were reached with various
vendors to extend payments under negotiated payment plans.

The Company's $1.0 million line of credit with Lakeside Bank expired in February
1997. The Company is experiencing working capital constraints which has hindered
operations. To lessen such constraints, on May 5, 1997 the Company entered into
a loan and security agreement with its principal shareholder, PICO Holdings
("PICO"), to provide working capital loans of up to $1.0 million. In connection
with the extension by PICO of such $1.0 million facility, the Company and PICO
restructured the terms of its $2.5 million subordinated convertible debenture
("Debenture"). In August 1997, the Company and PICO amended the loan and
security agreement increasing the facility by $1.0 million to $2.0 million. In
September 1997, the Company and PICO further amended the loan and security
agreement increasing the facility by $0.25 million to $2.25 million and
extending the due date for all borrowings on the facility, plus accrued interest
to December 31, 1997. See footnote 4 of the Notes to the Financial Statements
and Part II of this report for additional information regarding the loan
facility. 

In October 1997 the Company issued five million (5,000,000) shares of Common
Stock in exchange for five million dollars ($5,000,000), subject to the
Company's right to repurchase four million shares at one dollar ($1) per share
upon completion of a rights offering. See note 5 of the Footnotes to the
Financial Statements and Part II of this report for additional information
regarding the equity capital infusion.

Part II

ITEM 2.  CHANGES IN SECURITIES

  On September 22, 1997 the Company and PICO Holdings, Inc., ("Holdings")
executed a second amendment to the Loan and Security Agreement dated as of May
5, 1997, as amended on August 8, 1997 (the "Loan Agreement") to further increase
the amount of the secured loan from Holdings to the Company from $2.0 million to
$2.25 million. The terms of the Loan Agreement otherwise remained substantially
the same, except that the maturity date was extended to December 31, 1997. In
consideration of the amendment to the Loan Agreement, the Company granted
Holdings a Common Stock Purchase Warrant entitling Holdings to purchase a
minimum of 129,032 shares of the Company's Common Stock at a price per share
(the "Warrant Price") equal to the lesser of (a) the mean of the closing bid
price per share for the 20 trading days preceding exercise of the Warrant or (b)
$1.9375 per share. The Warrant expires on April 30, 2000.  In lieu of exercising
the Warrant for cash, Holdings may elect to receive shares of the Company's
Common Stock equal to the "value" of the Warrant determined in accordance with a
formula specified in the Warrant (the "Conversion Value").  The number of shares
of the Company's Common Stock subject to the Warrant and the Warrant Price will
be adjusted to reflect stock dividends; reclassifications or changes of
outstanding securities of the Company; any consolidation, merger or
reorganization of the Company; stock splits; issuances of rights, options or
warrants to all holders of shares of the Company's Common Stock exercisable at
less than the current market price per share; and other distributions to all
holders of shares of the Company's Common Stock.  In the event of any sale,
license or other disposition of all or substantially all of the assets of the
Company or any reorganization, consolidation or merger involving the Company in
which the holders of the Company's securities before the transaction
beneficially own less than 50% of the outstanding voting securities of the
surviving entity (an "Acquisition"), if the successor entity does not assume the
obligations of the Warrant and Holdings has not fully exercised the Warrant, the
unexercised portion of the Warrant will be deemed automatically converted into
shares of the Company's Common Stock at the Conversion Value.  Alternatively,
Holdings may elect to cause the Company to purchase the exercised portion of the
Warrant for cash upon the closing of any Acquisition for an amount equal to (a)
the fair market value of any consideration that would have been received had
Holdings exercised the unexercised portion of the Warrant immediately before the
record date for determining stockholders entitled to participate in the proceeds
of the Acquisition, less (b) the aggregate Warrant Price.  The Warrant also
provides for certain piggyback registration rights and a one-time demand
registration right.

In October 1997 Imprimis Investors LLC and Wexford Spectrum Investors LLC 
(collectively, the "Wexford Affiliates") expended $5.0 million to purchase 
five million shares of the Company's Common Stock and warrants to purchase 
five hundred thousand shares of the Company's Common Stock at an exercise 
price of $2.00 per

                                   Page 14
<PAGE>

share, exercisable at any time prior to October 15, 2002 (the "Initial 
Warrants").

  The Wexford Affiliates have acquired the Common Stock and the Warrants for 
investment purposes pursuant to a certain Stock and Warrant Purchase 
Agreement dated October 15, 1997, between PC Quote and the Wexford Affiliates 
(the "Purchase Agreement").  Pursuant to the terms of the Purchase Agreement, 
on October 15, 1997, the Wexford Affiliates purchased 1,450,000 shares of 
Common Stock and the Initial Warrants for a purchase price of $1.45 million.  
On October 20, 1997, pursuant to the terms of the Purchase Agreement, the 
Wexford Affiliates purchased an additional 550,000 shares of Common Stock for 
a purchase price of $0.55 million.  On October 23, 1997, pursuant to the 
terms of the Purchase Agreement, the Wexford Affiliates purchased an 
additional 3,000,000 shares of Common Stock for a purchase price of $3.0 
million.

  Up to four million of the shares of Common Stock purchased by the Wexford
Affiliates are subject to repurchase by PC Quote at a purchase price of $1.00
per share pursuant to the terms of the Purchase Agreement (the "Repurchase"). 
Pursuant to the terms of the Purchase Agreement, PC Quote will use its best
efforts to consummate the Repurchase from the proceeds of the Rights Offering. 
In the event that the Rights Offering is not completed on or prior to
January 24, 1998, the Wexford Affiliates will be entitled to receive, out of
escrow, warrants to purchase an additional 250,000 shares of Common Stock with
the same terms as the Initial Warrants and, in the event the Rights Offering is
not completed on or prior to February 28, 1998, the Wexford Affiliates will be
entitled to receive, out of escrow, warrants to purchase an additional 250,000
shares of Common Stock with the same terms as the Initial Warrants.  

  In contemplation of the Purchase Agreement, the Wexford Affiliates have 
agreed not to participate in the Rights Offering. On October 31, 1997 a Form 
S-2 Registration Statement was filed with the Securities and Exchange 
Commission for the rights offering.

                            COMMON STOCK PURCHASE WARRANT

    THIS CERTIFIES THAT, for value received, PICO HOLDINGS, INC., a

only during the period commencing upon the Date of Grant and ending on April

    4.   METHOD OF EXERCISE AND PAYMENT.

         (a)  METHOD OF EXERCISE.  Subject to Section 3 hereof and compliance 
with all applicable Federal and state securities laws, the purchase right 
represented by this Warrant may be exercised, in whole or in part and from 
time to time, by the Holder by (i) surrender of this Warrant and delivery of 
the Notice of Exercise (the form of which is attached hereto as Exhibit A), 
duly executed, at the principal office of the Company and (ii) payment to the

Price multiplied by the number of Shares then being purchased pursuant to one

<PAGE>


Warrant at the principal office of the Company together with a properly 
endorsed notice of exercise and notice of such election in which event the 
Company shall issue to the Holder a number of shares of Common Stock computed 
using the following formula:

                                    Y (A-B)
                              X = ___________

                                       A

Where X =  the number of shares of Common Stock to be issued to the Holder,

      Y =  the number of shares of Common Stock purchasable under the Warrant
           or, if only a portion of the Warrant is being exercised, the
           portion of the Warrant being canceled (at the date of such
           calculation),

      A =  the fair market value of one share of the Company's Common Stock
           (at the date of such calculation), and

      B =  the Warrant Price (as adjusted to the date of such calculation).

For purposes of the above calculation, fair market value of one share of 
Common Stock shall be determined by the Company's Board of Directors in good 
faith; provided, however, that where there exists a public market for the 
Company's Common Stock at the time of such exercise, fair market value shall 
mean the average over the preceding twenty trading days (or such fewer number 
of days as such public market has existed) of the mean of the closing bid and 
asked prices on the over-the-counter market as reported by Nasdaq, or if the 
Common Stock is then traded on a national securities exchange or the Nasdaq 
National Market, the average over the preceding twenty trading days (or such 
fewer number of days as the Common Stock has been so traded) of the closing 
sale prices on the principal national securities exchange or the National 
Market on which it is so traded.

         (d)  DELIVERY OF CERTIFICATE.  In the event of any exercise of the 
purchase right represented by this Warrant, certificates for the Shares so 
purchased shall be delivered to the Holder within ten days of delivery of the 
Notice of Exercise and, unless this Warrant has been fully exercised or has 
expired, a new warrant representing the portion of the Shares with respect to 
which this Warrant shall not then have been exercised shall also be issued to 
the Holder within such ten day period.

         (e)  NO FRACTIONAL SHARES.  No fractional shares shall be issued in
connection with any exercise hereunder, but in lieu of such fractional shares
the Company shall make a cash payment therefor upon the basis of the fair market
value per Share as of the date of exercise.


                                        3

         (f)  COMPANY'S REPRESENTATIONS.

              (i)  All Shares which may be issued upon the exercise of the 
purchase right represented by this Warrant shall, upon issuance, be duly 
authorized, validly issued, fully paid and nonassessable, and free of any 
liens and encumbrances except for restrictions on transfer under applicable 
federal and state securities laws.  During the period within which the 
purchase right represented by this Warrant may be exercised, the Company 
shall at all times use its best efforts to have authorized, and reserved for 
the purpose of issuance upon exercise of the purchase right represented by 
this Warrant, a sufficient number of Shares to provide for the exercise of 
the purchase right represented by this Warrant;

              (ii) This Warrant has been duly authorized and executed by the 
Company and is a valid and binding obligation of the Company enforceable in 
accordance with its terms, subject to applicable bankruptcy, insolvency, 
reorganization, moratorium or other laws of general application affecting the 
enforcement of creditors' rights;


              (iii)     The execution and delivery of this Warrant are not, 
and the issuance of the Shares upon exercise of this Warrant in accordance 
with the terms hereof will not be inconsistent with the Company's Certificate 
of Incorporation or Bylaws, do not and will not contravene any law, 
governmental rule or regulation, judgment or order applicable to the Company, 
and do not and will not conflict with or contravene any provision of, or 
constitute a default under, any material indenture, mortgage, contract or 
other instrument of which the Company is a party or by which it is bound, or 
require the registration or filing with or the taking of any action in 
respect of or by, any federal, state or local government authority or agency 
(other than such consents, approvals, notices, actions, or filings as have 
already been obtained or made, as the case may be).

    5.   ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES.  The number of 
securities issuable upon the exercise of this Warrant and the Warrant Price 
shall be subject to adjustment from time to time upon the occurrence of 
certain events, as follows:

         (a)  ADJUSTMENT FOR DIVIDENDS IN STOCK.  In case at any time or from 
time to time on or after the date hereof the holders of the Common Stock of 
the Company (or any shares of stock or other securities at the time 
receivable upon the exercise of this Warrant) shall have received or, on or 
after the record date fixed for the determination of eligible stockholders, 
shall have become entitled to receive, without payment therefor, other or 
additional stock of the Company by way of dividend then, and in each case, 
the Holder of this Warrant shall, upon the exercise hereof, be entitled to 
receive, in addition to the number of shares of Common Stock receivable 
thereupon, and without payment of any additional consideration therefor, the 
amount of such other or additional stock of the Company which such Holder 
would hold on the date of such exercise had it been the holder of record of 
such Common Stock on the date hereof and had thereafter, during the period 
from the date hereof to and including the date of such exercise, retained 
such shares and/or all other additional stock receivable by it as aforesaid 
during such period, giving effect to all adjustments called for during such 
period by paragraphs (b) and (c) of this Section 5.


                                        4
<PAGE>


         (b)  ADJUSTMENT FOR RECLASSIFICATION OR REORGANIZATION.  In case of 
any reclassification or change of the outstanding securities of the Company 
or of any consolidation, merger or reorganization of the Company on or after 
the date hereof, then and in each such case the Holder of this Warrant, upon 
the exercise hereof at any time after the consummation of such 
reclassification, change, consolidation, merger or reorganization, shall be 
entitled to receive, in lieu of or in addition to the stock or other 
securities and property receivable upon the exercise hereof prior to such 
consummation, the stock or other securities to which such Holder would have 
been entitled upon such consummation if such Holder had exercised this 
Warrant immediately prior thereto, all subject to further adjustment as 
provided in subparagraphs (a) and (c); in each such case, the terms of this 
Paragraph 5 shall be applicable to the shares of stock or other securities 
property receivable upon the exercise of this Warrant after such consummation.

         (c)  STOCK SPLITS AND REVERSE STOCK SPLITS.  If, at any time on or 
after the date hereof, the Company shall subdivide its outstanding shares of 
Common Stock into a greater number of shares, the Warrant Price in effect 
immediately prior to such subdivision shall thereby be proportionately 
reduced and the number of shares receivable upon exercise of this Warrant 
shall thereby be proportionately increased; and, conversely, if at any time 
on or after the date hereof the outstanding number of shares of Common Stock 
shall be combined into a smaller number of shares, the Warrant Price in 
effect immediately prior to such combination shall thereby be proportionately 
increased and the number of shares receivable upon exercise of the Warrant 
shall be proportionately decreased.

         (d)  RIGHTS, OPTIONS OR WARRANTS.  If the Company issues rights, 
options or warrants to all holders of its shares of Common Stock, without any 
charge to such holders, entitling them (for a period expiring within 45 days 
after the record date mentioned below in this paragraph (d)) to subscribe for 
or to purchase shares of Common Stock at a price per share lower than the 
then current market price per share of Common Stock at the record date 
mentioned below (as defined in paragraph (f) below), the number of Shares 
thereafter purchasable upon exercise of each Warrant shall be determined by 
multiplying the number of Shares theretofore purchasable upon exercise of 
each Warrant by a fraction, of which the numerator shall be the number of 
shares of Common Stock outstanding on such record date plus the number of 
additional shares of Common Stock offered for subscription or purchase, and 
of which the denominator shall be the number of shares of Common Stock 
outstanding on such record date plus the number of shares which the aggregate 
offering price of the total number of shares of Common Stock so offered would 
purchase at the then current market price per share of Common Stock.  Such 
adjustment shall be made whenever such rights, options or warrants are 
issued, and shall become effective retroactively to immediately after the 
record date for the determination of stockholders entitled to receive such 
rights, options or warrants.

         (e)  OTHER DISTRIBUTIONS.  If the Company distributes to all holders 
of its shares of Common Stock shares of stock other than Common Stock or 
evidences of its indebtedness or assets (excluding cash dividends payable out 
of consolidated earnings or retained earnings and dividends or distributions 
referred to in paragraph (a) above) or rights, options or warrants or 
convertible or exchangeable securities containing the right to subscribe for 
or purchase shares of Common Stock


                                        5
<PAGE>


(excluding those referenced in paragraph (2) above), then in each case the 
number of Shares thereafter issuable upon the exercise of each warrant shall 
be determined by multiplying the number of Shares theretofore issuable upon 
the exercise of each Warrant, by a fraction, of which the numerator shall be 
the current market price per share of Common Stock (as defined in paragraph 
(f) below) on the record date mentioned below in this paragraph (e), and of 
which the denominator shall be the current market price per share of Common 
Stock on such record date, less the then fair value (as determined in good 
faith by the Board of Directors of the Company, whose determination shall be 
conclusive) of the portion of the shares of stock other than the Common Stock 
or assets or evidences of indebtedness so distributed or of such subscription 
rights, options or warrants, or of such convertible or exchangeable 
securities applicable to one share of Common Stock.  Such adjustment shall be 
made whenever any such distribution is made, and shall become effective on 
the date of distribution retroactive to immediately after the record date for 
the determination of stockholders entitled to receive such distribution.

         (f)  CURRENT MARKET PRICE.  For the purposes of any computation 
under paragraphs (d) and (c) of this Section 5, the current market price per 
share of Common Stock at any date shall be the average of the daily closing 
prices for fifteen consecutive trading days commencing twenty trading days 
before the date of such computation.  The closing price for each day shall be 
the closing sale price or in case no such reported sale takes place on such 
day, the average of the closing bid and asked prices for such day, in either 
case on the principal national securities exchange or the Nasdaq National 
Market on which the shares are listed or admitted to trading, or if they are 
not listed or admitted to trading on any national securities exchange or the 
Nasdaq National Market, but are traded in the over-the-counter market, the 
average of the representative closing bid and asked quotations for the Common 
Stock, on the NASDAQ system or any comparable system, or if the Common Stock 
or, in case no sale is publicly reported, the average of the closing bid and 
asked prices as furnished by two members of the NASD selected from time to 
time by the Company for that purpose.

         (g)  ADJUSTMENTS TO WARRANT PRICE.  Whenever the number of Shares 
purchasable upon exercise of each Warrant is adjusted, as herein provided, 
the Warrant Price shall be adjusted by multiplying the Exercise Price in 
effect immediately prior to such adjustment by a fraction, of which the 
numerator shall be the number of Shares purchasable upon the exercise of each 
Warrant immediately prior to such adjustment, and of which the denominator 
shall be the number of Shares so purchasable immediately thereafter.

         (h)       CERTIFICATE AS TO ADJUSTMENTS.  Upon each adjustment of 
the Warrant Price, the Company at its expense shall promptly compute such 
adjustment, and furnish the Holder with a certificate of its Chief Financial 
Officer setting forth such adjustment and the facts upon which such 
adjustment is based.  The Company shall, upon written request, furnish the 
Holder a certificate setting forth the Warrant Price in effect upon the date 
thereof and the series of adjustments leading to such Warrant Price.

    6.   ACQUISITIONS


                                        6
<PAGE>


         (a)  ASSUMPTION OF WARRANT.  If upon the closing of any Acquisition 
the successor entity assumes the obligations of this Warrant, then this 
Warrant shall be exercisable for the same securities, cash, and property as 
would be payable for the Shares issuable upon exercise of the unexercised 
portion of this Warrant as if such Shares were outstanding on the record date 
for the Acquisition and subsequent closing.

         (b)  NONASSUMPTION.  If upon the closing of any Acquisition the 
successor entity does not assume the obligations of this Warrant and the 
Holder has not otherwise exercised this Warrant in full, then the unexercised 
portion of this Warrant shall be deemed to have been automatically converted 
pursuant to Section 4(c) and thereafter the Holder shall participate in the 
acquisition on the same terms as other holders of the same class of 
securities of the Company.

         (c)  PURCHASE RIGHT.  Notwithstanding the foregoing, at the election 
of the Holder, the Company shall purchase the unexercised portion of this 
Warrant for cash upon the closing of any Acquisition for an amount equal to 
(a) the fair market value of any consideration that would have been received 
by the Holder in consideration of the Shares had the Holder exercised the 
unexercised portion of this Warrant immediately before the record date for 
determining the stockholders entitled to participate in the proceeds of the 
Acquisition, less (b) the aggregate Warrant Price of the Shares, but in no 
event less than zero.

    7.   NOTICES; INFORMATION; REGISTRATION.

         (a)  NOTICE OF CERTAIN EVENTS.  If the Company proposes at any time 
(a) to declare any dividend or distribution upon its Common Stock, whether in 
cash, property, stock, or other securities and whether or not a regular cash 
dividend; (b) to offer for subscription pro rata to the holders of any class 
or series of its stock any additional shares of stock of any class or series 
or other rights; (c) to effect any reclassification or recapitalization of 
Common Stock; (d) to merge or consolidate with or into any other corporation, 
or sell, lease, license, or convey all or substantially all of its assets, or 
to liquidate, dissolve or wind up; or (e) offer holders of registration 
rights the opportunity to participate in an underwritten public offering of 
the company's securities for cash, then, in connection with each such event, 
the Company shall give the Holder (1) at least 20 days prior written notice 
of the date on which a record will be taken for such dividend, distribution, 
or subscription rights (and specifying the date on which the holders of 
Common Stock will be entitled thereto) or in respect of the matters referred 
to in (c) and (d) above for determining rights to vote, if any; (2) in the 
case of the matters referred to in (c) and (d) above at least 20 days prior 
written notice of the date when the same will take place (and specifying the 
date on which the holders of Common Stock will be entitled to exchange their 
Common Stock for securities or other property deliverable upon the occurrence 
of such event); and (3) in the case of the matter referred to in (e) above, 
the same notice as is given to the holders of such registration rights.

         (b)  INFORMATION RIGHTS.  So long as the Holder holds this Warrant 
and/or any of the Shares, the Company shall deliver to the Holder (a) 
promptly after mailing, copies of all notices or other written communications 
to the stockholders of the Company, (b) within ninety days after the end of 
each fiscal year of the Company, the annual audited financial statements of 
the Company audited by independent public accountants of recognized standing 
and (c) within forty-five days


                                        7
<PAGE>


after the end of each of the first three quarters of each fiscal year, the 
Company's quarterly, unaudited financial statements.

         (c)  REGISTRATION UNDER SECURITIES ACT OF 1933.  The Company agrees 
that the Shares shall be subject to the registration rights set forth on 
Exhibit B.

     8.  COMPLIANCE WITH ACT; TRANSFERABILITY AND NEGOTIABILITY OF WARRANT; 
DISPOSITION OF SHARES.

         (a)  COMPLIANCE WITH ACT.  The Holder, by acceptance hereof, agrees 
that this Warrant and the Shares to be issued upon the exercise hereof are 
being acquired solely for its own account and not as a nominee for any other 
party and not with a view toward the resale or distribution thereof and that 
it will not offer, sell or otherwise dispose of this Warrant or any Shares to 
be issued upon the exercise hereof except under circumstances which will not 
result in a violation of the Act.  This Warrant and the Shares to be issued 
upon the exercise hereof (unless registered under the Act) shall be imprinted 
with a legend in substantially the following form:

    THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
    THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, 
    TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE
    REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, 
    THE SALE IS MADE IN ACCORDANCE WITH RULE 144 UNDER THE ACT, OR THE
    COMPANY RECEIVES AN OPINION OF COUNSEL FOR THE HOLDER OF THESE 
    SECURITIES REASONABLY SATISFACTORY TO THE COMPANY, STATING THAT 
    SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM 
    THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

In addition, this Warrant and the Shares to be issued upon the exercise 
hereof shall bear any legends required by the securities laws of any 
applicable states.

         (b)  TRANSFERABILITY AND NEGOTIABILITY OF WARRANT.  This Warrant may 
not be transferred or assigned in whole or in part without compliance with 
all applicable federal and state securities laws by the transferor and the 
transferee (including the delivery of investment representation letters and 
legal opinions satisfactory to the Company, if requested by the Company and 
the transfer is to a person other than a general partner or affiliate of the 
initial Holder).  Subject to the provisions of this Warrant with respect to 
compliance with the Act, title to this Warrant may be transferred by 
endorsement and delivery in the same manner as a negotiable instrument 
transferable by endorsement and delivery.  The Company shall act promptly to 
record transfers of this Warrant on its books, but the Company may treat the 
registered holder of this Warrant as the absolute owner of this Warrant for 
all purposes, notwithstanding any notice to the contrary.

         (c)  DISPOSITION OF SHARES.  With respect to any offer, sale, 
transfer or other disposition of any Shares acquired pursuant to the exercise 
of this Warrant prior to registration of


                                        8
<PAGE>


such Shares, except for any such offer, sale, transfer or other disposition 
of Shares to an affiliate of the initial Holder, the Holder and each 
subsequent holder of this Warrant agrees to give written notice to the 
Company prior thereto, describing briefly the manner thereof, and if such 
transfer is not pursuant to Rule 144, a written opinion of legal counsel for 
such holder, if requested by the Company, to the effect that such offer, sale 
or other disposition may be effected without registration or qualification of 
such Shares.  Notwithstanding the foregoing, such Shares may be offered, sold 
or otherwise disposed of in accordance with Rule 144, provided that the 
Company shall have been furnished with such information as the Company may 
reasonably request to provide a reasonable assurance that the provisions of 
Rule 144 have been satisfied.  Each certificate representing the Shares thus 
transferred (except a transfer pursuant to Rule 144) shall bear a restrictive 
legend as to the applicable restrictions on transferability in order to 
insure compliance with the Act, unless in the aforesaid opinion of legal 
counsel for the holder, such legend is not required in order to insure 
compliance with the Act.

    9.   RIGHTS OF STOCKHOLDERS.  No Holder shall be entitled to vote or 
receive dividends or be deemed the holder of Shares or any other securities 
of the Company which may at any time be issuable on the exercise of this 
Warrant for any purpose, nor shall anything contained herein be construed to 
confer upon the Holder, as such, any of the rights of a stockholder of the 
Company or any right to vote for the election of directors or upon any matter 
submitted to stockholders at any meeting thereof, or to give or withhold 
consent to any corporate action (whether upon any recapitalization, issuance 
of stock, reclassification of stock, consolidation, merger, transfer of 
assets or otherwise) or, except as expressly required herein, to receive 
notice of meetings, or to receive dividends or subscription rights or 
otherwise until this Warrant shall have been exercised and the Shares 
issuable upon exercise hereof shall have become deliverable, as provided 
herein.

    10.  REPLACEMENT OF WARRANTS.  On receipt of evidence reasonably 
satisfactory to the Company of the loss, theft, destruction or mutilation of 
this Warrant and, in the case of loss, theft or destruction, on delivery of 
an indemnity agreement reasonably satisfactory in form and amount to the 
Company or, in the case of mutilation, on surrender and cancellation of this 
Warrant, the Company at its expense shall execute and deliver, in lieu of 
this Warrant, a new warrant of like tenor.

    11.  EXCHANGE OF WARRANT.  Subject to the other provisions of this 
Warrant, on surrender of this Warrant for exchange, and subject to the 
provisions of this Warrant with respect to compliance with the Act, the 
Company at its expense shall issue to or on the order of the Holder a new 
warrant or warrants of like tenor, in the name of the Holder or as the Holder 
(on payment by the Holder of any applicable transfer taxes) may direct, for 
the number of Shares issuable upon exercise thereof.

    12.  NOTICES.  All notices and other communications from the Company to 
the Holder, or vice versa, shall be deemed delivered and effective when given 
personally or mailed by first-class registered or certified mail, postage 
prepaid, at such address as may have been furnished to the Company or the 
Holder, as the case may be, in writing by the Company or such Holder from 
time to time.

    13.  WAIVER.  This Warrant and any term hereof may be changed, waived, 
discharged or terminated only by an instrument in writing signed by the party 
against which enforcement of such change, waiver, discharge or termination is 
sought.

    14.  GOVERNING LAW.  This Warrant shall be governed by and construed in 
accordance with the laws of the State of Delaware.

                                   EXHIBIT B


                        STATEMENT OF REGISTRATION RIGHTS


    1.   DEFINITIONS.  For purpose of the Warrant to which this Statement of
Registration Rights is attached as Exhibit B:

         (a)  The terms "register," "registered," and "registration" refer to 
a registration effected by preparing and filing a registration statement or 
similar document in compliance with the Securities Act of 1933, as amended 
(the "Act"), and the declaration or ordering of effectiveness of such 
registration statement or document;

         (b)  The term "Registrable Securities" means the shares of Common 
Stock issued or issuable upon exercise of the Warrant;

         (c)  The term "Holder" means the original holder of the Warrant and 
any transferee of the Warrant; and

         (d)  The term "Warrant" means the original Warrants issued in 
connection with the Company's initial public offering and all Warrants issued 
as a result of the transfer of such original Warrants.

    2.   COMPANY REGISTRATION.  If (but without any obligation to do so) the 
Company proposes at any time before April 30, 2000 to register (including for 
this purpose a registration effected by the Company for stockholders other 
than Holder) any of its stock or other securities under the Act in connection 
with the public offering of such securities solely for cash (other than a 
registration relating solely to the sale of securities to participants in a 
Company stock plan, or a registration on any form which does not include 
substantially the same information as would be required to be included in a 
registration statement covering the sale of the Registrable Securities), the 
Company shall, at such time, promptly give Holder written notice of such 
registration.  Upon the written request of Holder given within twenty days 
after mailing of such notice by the Company, the Company shall, subject to 
the provisions of Section 8 hereof and Section 5 of the Warrant, cause to be 
registered under the Act all of the Registrable Securities that each such 
Holder has requested to be registered.

    3.   DEMAND REGISTRATION.  In case the Company shall, at any time before 
April 30, 2000, receive from Holders holding 40% or more of the outstanding 
Registrable Securities a written request (to be exercised only once) that the 
Company effect a registration and any related qualification or compliance 
with respect to all or a part of the Registrable Securities (which 
registration shall at the election of Holder either be for a registration for 
a primary issuance of the Shares upon the exercise of the Warrant or the 
resale of the Shares previously issued upon exercise of the Warrant at the 
election of Holder) owned by such Holder, the Company will promptly notify 
each other Holder (if any) of such request and will:


<PAGE>


         (a)  as soon as practicable, effect such registration and all such 
qualifications and compliances as may be so requested and as would permit or 
facilitate the sale and distribution of all or such portion of a Holder's 
Registrable Securities as are specified in such request, together with all or 
such portion of the Registrable Securities of any other holder of 
registration rights joining in such request as are specified in a written 
request given within 20 days after receipt of such written notice from the 
Company; PROVIDED, HOWEVER, that the Company shall not be obligated to effect 
any such registration, qualification or compliance, pursuant to this Section 
3:  (1) if the Company has effected a registration of Registrable Securities 
pursuant to this Section 3 within the preceding 12 months; (2) if the Company 
shall furnish to Holder a certificate signed by the President of the Company 
stating that in the good faith judgment of the Board of Directors of the 
Company, it would be seriously detrimental to the Company and its 
stockholders for such registration to be effected at such time, in which 
event the Company shall have the right to defer the filing of the 
registration statement for a period of not more than 60 days after receipt of 
the request of Holder under this Section 3; PROVIDED, HOWEVER, that the 
Company shall not utilize this right more than once in any twelve-month 
period; or (3) in any jurisdiction in which the Company would be required to 
qualify to do business or to execute a general consent to service of process 
in effecting such registration, qualification or compliance; and,

         (b)  subject to the foregoing, file a registration statement 
covering the Registrable Securities and other securities so requested to be 
registered promptly after receipt of the request or requests of Holder, and 
in any event within 30 days of receipt of such request.

    4.   OBLIGATION OF THE COMPANY.  Subject to the terms of the Warrant, in 
the event that the Company is to effect the registration of any Registrable 
Securities pursuant to Section 2 or 3 hereof, the Company shall promptly:

         (a)  Prepare and file with the SEC a registration statement with 
respect to such Registrable Securities and use its best efforts to cause such 
registration statement to become effective, and, upon the request of the 
holders of a majority of the securities registered thereunder, keep such 
registration statement effective for up to one hundred twenty (120) days, or 
such shorter period as is required to dispose of all securities covered by 
such registration statement.

         (b)  Prepare and file with the SEC such amendments and supplements 
to such registration statement and the prospectus used in connection with 
such registration statement as may be necessary to comply with the provisions 
of the Act with respect to the disposition of all securities covered by such 
registration statement.

         (c)  Furnish to Holder such number of copies of a prospectus, 
including a preliminary prospectus, in conformity with the requirements of 
the Act, and such other documents as Holder may reasonably request in order 
to facilitate the disposition of Registrable Securities owned by Holder.


                                        2
<PAGE>


         (d)  Use its best efforts to register and qualify the securities 
covered by such registration statement under such other securities or Blue 
Sky laws of such jurisdictions as shall be reasonably requested by Holder, 
provided that the Company shall not be required in connection therewith or as 
a condition thereto to qualify to do business or to file a general consent to 
service of process in any such states or jurisdictions or to agree to any 
restrictions as to the conduct of its business in the ordinary course thereof.

         (e)  In the event of any underwritten public offering, enter into 
and perform its obligations under an underwriting agreement, in usual and 
customary form, with the managing underwriter of such offering.  Holder shall 
also enter into and perform its obligations under such underwriting agreement.

         (f)  Notify Holder at any time when a prospectus relating to 
Registrable Securities of Holder covered by such registration statement is 
required to be delivered under the Act, of the happening of any event as a 
result of which the prospectus included in such registration statement, as 
then in effect, includes an untrue statement of a material fact or omits to 
state a material fact required to be stated therein or necessary to make the 
statements therein not misleading in the light of the circumstances under 
which they were made.

         (g)  Furnish, at the request of Holder, on the date that such 
Registrable Securities are delivered to the underwriters for sale in 
connection with a registration pursuant to the Warrant, if such securities 
are being sold through underwriters, or, if such securities are not being 
sold through underwriters, on the date that the registration statement with 
respect to such securities becomes effective, (i) an opinion, dated such 
date, of counsel representing the Company for the purposes of such 
registration, in form and substance as is customarily given to underwriters 
in an underwritten public offering, addressed to the underwriters, if any, 
and to Holder and (ii) a letter dated such date, from the independent 
certified public accountants of the Company, in form and substance as is 
customarily given by independent certified public accountants to underwriters 
in an underwritten public offering, addressed to the underwriters, if any, 
and to Holder.

    5.   AVAILABILITY OF RULE 144.  Notwithstanding anything in the Warrant 
or this Statement of Registration Rights to the contrary, the Company shall 
not be obligated to effect any such registration, qualification or 
compliance, pursuant to Section 2 or 3, if application of Rule 144 would 
allow Holder requesting a registration under Section 2 or 3 to dispose of the 
Registrable Securities for which a registration is demanded within a single 
90-day period.

    6.   FURNISH INFORMATION.  It shall be a condition precedent to the 
obligations of the Company to take any action pursuant to the Warrant that 
the selling Holder shall furnish to the Company such information regarding 
itself, the Registrable Securities held by Holder, and the intended method of 
disposition of such securities as shall be required to effect the 
registration of their Registrable Securities.


                                        3
<PAGE>


    7.   EXPENSES.  The Company shall bear and pay all expenses (other than 
underwriting discounts and commissions) incurred in connection with any 
registration, filing or qualification of Registrable Securities, including 
(without limitation) all registration, filing, and qualification fees, legal, 
printers and accounting fees relating thereto, and the cost of any reasonable 
fees or disbursements of counsel for Holder.

    8.   UNDERWRITING REQUIREMENTS.  In connection with any registrations in 
which Registrable Securities have a right to be included pursuant to Section 
2 hereof and which involves an underwriting of securities being issued by the 
Company, the Company shall not be required, under Section 2 hereof, to 
include any of Holder's securities in such underwriting unless Holder accepts 
the terms of the underwriting as agreed upon between the Company and the 
underwriters selected by it, and then only in such quantity as will not, in 
the opinion of the underwriters, jeopardize the success of the offering by 
the Company.  If the total amount of securities, including Registrable 
Securities, requested by stockholders to be included in such offering exceeds 
the amount of securities sold other than by the Company that the underwriters 
reasonably believe compatible with the success of the offering, then the 
Company shall be required to include in the offering only that number of such 
securities, including Registrable Securities, which the underwriters believe 
will not jeopardize the success of the offering, the securities so included 
to be apportioned pro rata among the selling Holder and other shareholders 
holding contractual registration rights according to the total amount of 
securities entitled to be included therein owned by each selling stockholder 
or in such other proportions as shall mutually be agreed to by Holder and 
each other selling stockholder.

    9.   INDEMNIFICATION.  In the event any Registrable Securities are 
included in a registration statement filed by the Company:

         (a)  The Company will indemnify and holder harmless Holder, its 
officers, directors, and agents, any underwriter (as defined in the Act) for 
Holder and each person, if any, who controls Holder or underwriter within the 
meaning of the Act or the Securities Exchange Act of 1934, as amended (the 
"1934 Act"), against any losses, claims, damages, or liabilities (joint or 
several) asserted by a third party to which they may become subject under the 
Act, the 1934 Act or other federal or state law, insofar as such losses, 
claims, damages, or liabilities (or actions in respect thereof) arise out of 
or are based upon any of the following statements, omissions or violations 
(collectively a "Violation"):  (i) any untrue statement or alleged untrue 
statement of a material fact contained in such registration statement, 
including any preliminary prospectus or final prospectus contained therein or 
any amendments or supplements thereto, (ii) the omission or alleged omission 
to state therein a material fact required to be stated therein, or necessary 
to make the statements therein not misleading, or (iii) any violation or 
alleged violation of the Company of the Act, the 1934 Act, any state 
securities law or any rule or regulation promulgated under the Act, the 1934 
Act or any state securities law; and the Company will reimburse Holder, any 
of its officers or directors, underwriter or controlling person for any legal 
or other expenses reasonably incurred by them, as incurred, in connection 
with investigating or defending any such loss, claim, damage, liability, or 
action; PROVIDED, HOWEVER, that the indemnity agreement contained in this 
Section 9(a) shall not apply to amounts paid in settlement of any such loss, 
claim, damage, liability or action if such settlement is effected without the 
consent of the Company (which consent shall not be 


                                        4
<PAGE>


unreasonably withheld), nor shall the Company be liable in any such case for 
any such loss, claim, damage, liability, or action to the extent that it 
arises out of or is based upon a Violation which occurs in reliance upon and 
in conformity with written information furnished expressly for use in 
connection with such registration by such Holder, underwriter or controlling 
person.

         (b)  Holder will indemnify and hold harmless the Company, each of 
its directors, each of its officers who have signed the registration 
statement, each person, if any, who controls the Company with the meaning of 
the Act, any underwriter and any other shareholder selling securities in such 
registration statement or any of its directors or officers or any person who 
controls such shareholder, against any losses, claims, damages, or 
liabilities (joint or several) asserted by a third party to which the Company 
or any such director, officer, controlling person, or underwriter or 
controlling person, or other such shareholder or director, officer or 
controlling person may become subject, under the Act, the 1934 Act or other 
federal or state law, insofar as such losses, claims, damages, or liabilities 
(or actions in respect thereto) arise out of or are based upon any Violation, 
in each case to the extent (and only to the extent) that such Violation 
occurs in reliance upon and in conformity with written information furnished 
by Holder expressly for use in connection with such registration; and Holder 
will reimburse any legal or other expenses reasonably incurred by the Company 
or any such director, officer, controlling person, underwriter or controlling 
person, other shareholder, officer, director, or controlling person, as 
incurred, in connection with investigating or defending any such loss, claim, 
damage, liability, or action; PROVIDED, HOWEVER, that the obligations of 
Holder hereunder shall be limited to an amount equal to the net proceeds 
(equal to the offering price less the exercise price, expenses and 
underwriting commissions and discounts) to such Holder of Shares sold as 
contemplated herein.  Notwithstanding the foregoing, the indemnity agreement 
contained in this Section 9(b) shall not apply to amounts paid in settlement 
of any such loss, claim, damage, liability or action if such settlement is 
effected without the consent of Holder, which consent shall not be 
unreasonably withheld.

         (c)  Promptly after receipt by an indemnified party under this 
Section 9 of notice of the commencement of any action (including any 
governmental action), such indemnified party will, if a claim in respect 
thereof is to be made against any indemnifying part under this Section 9, 
deliver to the indemnifying party a written notice of the commencement 
thereof and the indemnifying party shall have the right to participate in, 
and, to the extent the indemnifying party so desires, jointly with any other 
indemnifying party similarly noticed, to assume the defense thereof with 
counsel mutually satisfactory to the parties; PROVIDED, HOWEVER, that an 
indemnified party shall have the right to retain its own counsel, with the 
fees and expenses to be paid by the indemnifying party, if representation of 
such indemnified party by the counsel retained by the indemnifying party 
would be inappropriate due to actual or potential differing interests between 
such indemnified party and any other party represented by such counsel in 
such proceeding.  The failure to deliver written notice to the indemnifying 
party within a reasonable time of the commencement of any such action, if 
prejudicial to its ability to defend such action, shall relieve such 
indemnifying party of any liability to the indemnified party under this 
Section 9, but the omission so to deliver written notice to the indemnifying 
party will not relieve it of any liability that it may have to any 
indemnified party otherwise than under this Section 9.

                                      5

    10.  REPORTS UNDER THE 1934 ACT.  With a view to making available to 
Holder the benefits of Rule 144 promulgated under the Act and any other rule 
or regulation of the SEC that may at any time permit Holder to sell 
securities of the Company to the public without registration the Company will 
endeavor to:

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

         (b)  take such action as is necessary to enable Holder to utilize an 
abbreviated registration statement for the sale of its Registrable Securities;

         (c)  file with the SEC in a timely manner all reports and other 
documents required of the Company under the Act and the 1934 Act; and

         (d)  furnish to Holder, so long as Holder owns any Registrable 
Securities, forthwith upon request (i) a written statement by the Company 
that it has complied with the reporting requirements of SEC Rule 144, the Act 
and the 1934 Act, or that it qualifies as a registrant whose securities may 
be resold pursuant to Form S-3 (at any time after it so qualifies), (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 in availing Holder of any rule or 
regulation of the SEC which permits the selling of any such securities 
without registration or pursuant to such form.

    11.  ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause the Company 
to register Registrable Securities pursuant to the Warrant may be assigned by 
Holder to a permitted transferee or assignee of the Warrant or of at least 
400,000 Shares, provided the Company is, within a reasonable time after such 
transfer, furnished with written notice of the name and address of such 
transferee or assignee and the securities with respect to which such 
registration rights are being assigned; and provided, further, that such 
assignment shall be effective only if immediately following such transfer the 
further disposition of such securities by the transferee or assignee is 
restricted under the Act.

              (i)  The Company is soliciting proxies in connection with its 
Annual Meeting of Stockholders for, among other things, a proposal to amend 
its Certificate of Incorporation to increase the number of shares of Common 
Stock authorized for issuance.  If such proposal is approved by the Company's 
stockholders, the Company shall file a Certificate of Amendment to its 
Certificate of Incorporation with the Secretary of State of the State of 
Delaware (the "Amendment") in order to increase such number of authorized 
shares of Common Stock.  From and after the date of filing the Amendment, all 
Shares which may be issued upon the exercise of the purchase right 
represented by this Warrant shall, upon issuance, be duly authorized, validly 
issued, fully paid and non-assessable, and free of any liens and encumbrances 
except for restrictions on transfer under applicable federal and state 
securities laws.  From and after the date of the Amendment, during the period 
within which the purchase right represented by this Warrant may be exercised, 
the Company shall at all times use its best efforts to have authorized, and 
reserved for the purpose of issuance upon exercise of the purchase right 
represented by this Warrant, a sufficient number of Shares to provide for the 
exercise of the purchase right represented by this Warrant;

              (ii) This Warrant has been duly authorized and executed by the 
Company and is a valid and binding obligation of the Company enforceable in 
accordance with its terms, subject to applicable bankruptcy, insolvency, 
reorganization, moratorium or other laws of general application affecting the 
enforcement of creditors' rights;
              
              (iii)     The execution and delivery of this Warrant are not, 
and from and after the date of the Amendment, the issuance of the Shares upon 
exercise of this Warrant in accordance with the terms hereof will not be, 
inconsistent with the Company's Certificate of Incorporation or Bylaws, do 
not and will not contravene any law, governmental rule or regulation, 
judgment or order applicable to the Company, and do not and will not conflict 
with or contravene any provision of, or constitute a default under, any 
material indenture, mortgage, contract or other instrument of which the 
Company is a party or by which it is bound, or require the registration or 
filing with or the taking of any action in respect of or by, any federal, 
state or local government authority or agency (other than such consents, 
approvals, notices, actions, or filings as have already been obtained or 
made, as the case may be).

events, as follows:

         (a)  ADJUSTMENT FOR DIVIDENDS IN STOCK.  In case at any time or from 
time to time on or after the date hereof the holders of the Common Stock of 
the Company (or any shares of stock or other securities at the time 
receivable upon the exercise of this Warrant) shall have received or, on or 
after the record date fixed for the determination of eligible stockholders, 
shall have become entitled to receive, without payment therefor, other or 
additional stock of the Company by way of dividend then, and in each case, 
the Holder of this Warrant shall, upon the exercise hereof, be entitled to 
receive, in addition to the number of shares of Common Stock receivable 
thereupon, and without payment of any additional  consideration therefor, the 
amount of such other or additional stock of the Company which such Holder 
would hold on the date of such exercise had it been the holder of record of 
such Common Stock on the date hereof and had thereafter, during the period 
from the date hereof to and including the date of such exercise, retained 
such shares and/or all other additional stock receivable by it as aforesaid 
during such period, giving effect to all adjustments called for during such 
period by paragraphs (b) and (c) of this Section 5.
         
         (b)  ADJUSTMENT FOR RECLASSIFICATION OR REORGANIZATION.  In case of 
any reclassification or change of the outstanding securities of the Company 
or of any consolidation, merger or reorganization of the Company on or after 
the date hereof, then and in each such case the Holder of this Warrant, upon 
the exercise hereof at any time after the consummation of such 
reclassification, change, consolidation, merger or reorganization, shall be 
entitled to receive, in lieu of or in addition to the stock or other 
securities and property receivable upon the exercise hereof prior to such 
consummation, the stock or other securities to which such Holder would have 
been entitled upon such consummation if such Holder had exercised this 
Warrant immediately prior thereto, all subject to further adjustment as 
provided in subparagraphs (a) and (c); in each such case, the terms of this 
Paragraph 5 shall be applicable to the shares of stock or other securities 
property receivable upon the exercise of this Warrant after such consummation.
         
         (c)  STOCK SPLITS AND REVERSE STOCK SPLITS.  If, at any time on or 
after the date hereof, the Company shall subdivide its outstanding shares of 
Common Stock into a greater number of shares, the Warrant Price in effect 
immediately prior to such subdivision shall thereby be proportionately 
reduced and the number of shares receivable upon exercise of this Warrant 
shall thereby be proportionately increased; and, conversely, if at any time 
on or after the date hereof the outstanding number of shares of Common Stock 
shall be combined into a smaller number of shares, the Warrant Price in 
effect immediately prior to such combination shall thereby be proportionately 
increased and the number of shares receivable upon exercise of the Warrant 
shall be proportionately decreased.
         
         (d)  ADJUSTMENTS TO WARRANT PRICE.  Whenever the number of Shares 
purchasable upon exercise of this Warrant is adjusted, as herein provided, 
the Warrant Price shall be adjusted by multiplying the Exercise Price in 
effect immediately prior to such 

                                       4
<PAGE>

adjustment by a fraction, of which the numerator shall be the number of 
Shares purchasable upon the exercise of each Warrant immediately prior to 
such adjustment, and of which the denominator shall be the number of Shares 
so purchasable immediately thereafter.
         
         (e)  CERTIFICATES AS TO ADJUSTMENTS.  Upon each adjustment of the 
Warrant Price, the Company at its expense shall promptly compute such 
adjustment, and furnish the Holder with a certificate of its Chief Financial 
Officer setting forth such adjustment and the facts upon which such 
adjustment is based.  The Company shall, upon written request, furnish the 
Holder a certificate setting forth the Warrant Price in effect upon the date 
thereof and the series of adjustments leading to such Warrant Price.

    6.   ACQUISITIONS.

         (a)  ASSUMPTION OF WARRANT.  If upon the closing of any Acquisition 
the successor entity assumes the obligations of this Warrant, then this 
Warrant shall be exercisable for the same securities, cash, and property as 
would be payable for the Shares issuable upon exercise of the unexercised 
portion of this Warrant as if such Shares were outstanding on the record date 
for the Acquisition and subsequent closing.
         
         (b)  NONASSUMPTION.  If upon the closing of any Acquisition the 
successor entity does not assume the obligations of this Warrant and the 
Holder has not otherwise exercised this Warrant in full, then the unexercised 
portion of this Warrant shall be deemed to have been automatically converted 
pursuant to Section 4(c) and thereafter the Holder shall participate in the 
acquisition on the same terms as other holders of the same class of 
securities of the Company.

    7.   NOTICES; INFORMATION; REGISTRATION.

         (a)  NOTICE OF CERTAIN EVENTS.  If the Company proposes at any time 
(a) to effect any reclassification or recapitalization of Common Stock; (b) 
to merge or consolidate with or into any other corporation, or sell, lease, 
license, or convey all or substantially all of its assets, or to liquidate, 
dissolve or wind up; or (c) offer holders of registration rights the 
opportunity to participate in an underwritten public offering of the 
company's securities for cash, then, in connection with each such event, the 
Company shall give the Holder at least 14 days prior written notice of the 
date on which a record will be taken for such action.  
         
         (b)  INFORMATION RIGHTS.  So long as the Holder holds this Warrant 
and/or any of the Shares, the Company shall deliver to the Holder (a) 
promptly after mailing, copies of all notices or other written communications 
to the stockholders of the Company, (b) within ninety days after the end of 
each fiscal year of the Company, the annual audited financial statements of 
the Company audited by independent public accountants of recognized standing 
and (c) within forty-five days after the end of each of the first three 
quarters of each fiscal year, the Company's quarterly, unaudited financial 
statements.

                                       5
<PAGE>

         (c)  REGISTRATION UNDER SECURITIES ACT OF 1933.  The Company agrees 
that the Shares shall be subject to the registration rights set forth on 
Exhibit B.

    8.   COMPLIANCE WITH ACT; TRANSFERABILITY AND NEGOTIABILITY OF WARRANT;   
         DISPOSITION OF SHARES.

         (a)  COMPLIANCE WITH ACT.  The Holder, by acceptance hereof, agrees 
that this Warrant and the Shares to be issued upon the exercise hereof are 
being acquired solely for its own account and not as a nominee for any other 
party and not with a view toward the resale or distribution thereof and that 
it will not offer, sell or otherwise dispose of this Warrant or any Shares to 
be issued upon the exercise hereof except under circumstances which will not 
result in a violation of the Act.  This Warrant and the Shares to be issued 
upon the exercise hereof (unless registered under the Act) shall be imprinted 
with a legend in substantially the following form:
         
    THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
    SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED,
    ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION
    STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN
    ACCORDANCE WITH RULE 144 UNDER THE ACT, OR THE COMPANY RECEIVES AN
    OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY
    SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER,
    ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND
    PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

In addition, this Warrant and the Shares to be issued upon the exercise 
hereof shall bear any legends required by the securities laws of any 
applicable states.

         (b)  TRANSFERABILITY AND NEGOTIABILITY OF WARRANT.  This Warrant may 
not be transferred or assigned in whole or in part without compliance with 
all applicable federal and state securities laws by the transferor and the 
transferee (including the delivery of investment representation letters and 
legal opinions satisfactory to the Company, if requested by the Company and 
the transfer is to a person other than a general partner or affiliate of the 
initial Holder).  Subject to the provisions of this Warrant with respect to 
compliance with the Act, title to this Warrant may be transferred by 
endorsement and delivery in the same manner as a negotiable instrument 
transferable by endorsement and delivery.  The Company shall act promptly to 
record transfers of this Warrant on its books, but the Company may treat the 
registered holder of this Warrant as the absolute owner of this Warrant for 
all purposes, notwithstanding any notice to the contrary.

                                  
                                       6
<PAGE>

         (c)  DISPOSITION OF SHARES.  With respect to any offer, sale, 
transfer or other disposition of any Shares acquired pursuant to the exercise 
of this Warrant prior to registration of such Shares, except for any such 
offer, sale, transfer or other disposition of Shares to an affiliate of the 
initial Holder, the Holder and each subsequent holder of this Warrant agrees 
to give written notice to the Company prior thereto, describing briefly the 
manner thereof, and if such transfer is not pursuant to Rule 144, a written 
opinion of legal counsel for such holder, if requested by the Company, to the 
effect that such offer, sale or other disposition may be effected without 
registration or qualification of such Shares.  Notwithstanding the foregoing, 
such Shares may be offered, sold or otherwise disposed of in accordance with 
Rule 144, provided that the Company shall have been furnished with such 
information as the Company may reasonably request to provide a reasonable 
assurance that the provisions of Rule 144 have been satisfied.  Each 
certificate representing the Shares thus transferred (except a transfer 
pursuant to Rule 144) shall bear a restrictive legend as to the applicable 
restrictions on transferability in order to insure compliance with the Act, 
unless in the aforesaid opinion of legal counsel for the holder, such legend 
is not required in order to insure compliance with the Act.

    9.   RIGHTS OF STOCKHOLDERS.  No Holder shall be entitled to vote or 
receive dividends or be deemed the holder of Shares or any other securities 
of the Company which may at any time be issuable on the exercise of this 
Warrant for any purpose, nor shall anything contained herein be construed to 
confer upon the Holder, as such, any of the rights of a stockholder of the 
Company or any right to vote for the election of directors or upon any matter 
submitted to stockholders at any meeting thereof, or to give or withhold 
consent to any corporate action (whether upon any recapitalization, issuance 
of stock, reclassification of stock, consolidation, merger, transfer of 
assets or otherwise) or, except as expressly required herein, to receive 
notice of meetings, or to receive dividends or subscription rights or 
otherwise until this Warrant shall have been exercised and the Shares 
issuable upon exercise hereof shall have become deliverable, as provided 
herein.

    10.  REPLACEMENT OF WARRANTS.  On receipt of evidence reasonably 
satisfactory to the Company of the loss, theft, destruction or mutilation of 
this Warrant and, in the case of loss, theft or destruction, on delivery of 
an indemnity agreement reasonably satisfactory in form and amount to the 
Company or, in the case of mutilation, on surrender and  cancellation of this 
Warrant, the Company at its expense shall execute and deliver, in lieu of 
this Warrant, a new warrant of like tenor.

    11.  EXCHANGE OF WARRANT.  Subject to the other provisions of this 
Warrant, on surrender of this Warrant for exchange, and subject to the 
provisions of this Warrant with respect to compliance with the Act, the 
Company at its expense shall issue to or on the order of the Holder a new 
warrant or warrants of like tenor, in the name of the Holder or as the Holder 
(on payment by the Holder of any applicable transfer taxes) may direct, for 
the number of Shares issuable upon exercise thereof.

    12.  NOTICES.  All notices and other communications from the Company to 
the Holder, or vice versa, shall be deemed delivered and effective when given 
personally or

                                  7
<PAGE>

mailed by first-class registered or certified mail, postage prepaid, at such 
address as may have been furnished to the Company or the Holder, as the case 
may be, in writing by the Company or such Holder from time to time.

    13.  WAIVER.  This Warrant and any term hereof may be changed, waived, 
discharged or terminated only by an instrument in writing signed by the party 
against which enforcement of such change, waiver, discharge or termination is 
sought.

    14.  GOVERNING LAW.  This Warrant shall be governed by and construed in 
accordance with the laws of the State of Delaware.

    15.  TITLES AND SUBTITLES; FORMS OF PRONOUNS.  The titles of the Sections 
and Subsections of this Warrant are for convenience only and are not to be 
considered in construing this Warrant.  All pronouns used in this Warrant 
shall be deemed to include masculine, feminine and neuter forms.
    
    16.  ATTORNEYS' FEES.  In the event of any dispute between the parties 
concerning the terms and provisions of this Warrant, the party prevailing in 
such dispute shall be entitled to collect from the other party all costs 
incurred in such dispute, including reasonable attorneys' fees.

                                   EXHIBIT B

                        STATEMENT OF REGISTRATION RIGHTS

          1.  DEFINITIONS.  For purposes of the Warrant to which this 
Statement of Registration Rights is attached as Exhibit B:

              (a)  The terms "register," "registered," and "registration" 
refer to a registration effected by preparing and filing a registration 
statement or similar document in compliance with the Securities Act of 1933, 
as amended (the "Act"), and the declaration or ordering of effectiveness of 
such registration statement or document;
                                        
              (b)  The term "Registrable Securities" means the shares of 
Common Stock issued or issuable upon exercise of the Warrant;
                                        
              (c)  The term "Holder" means the original holder of the Warrant 
and any transferee of the Warrant; and
                                        
              (d)  The term "Warrant" means the original Warrants issued in 
connection with the Stock and Warrant Purchase Agreement, dated as of October 
15, 1997, between the Company, as Seller, and Imprimis Investors LLC, a 
Delaware limited liability company, and Wexford Spectrum Investors LLC, a 
Delaware limited liability company, as Buyers, and all Warrants issued as a 
result of the transfer of such original Warrants.

          2.  COMPANY REGISTRATION.  If (but without any obligation to do so) 
the Company proposes at any time before October 15, 2002 to register 
(including for this purpose a registration effected by the Company for 
stockholders other than Holder) any of its stock or other securities under 
the Act in connection with the public offering for its own account of such 
securities solely for cash (other than a registration relating solely to the 
sale of securities to participants in a Company stock plan, or a registration 
on any form which does not include substantially the same information as 
would be required to be included in a registration statement covering the 
sale of the Registrable Securities), the Company shall, at such time, 
promptly give Holder written notice of such registration.  Upon the written 
request of Holder given within twenty days after mailing of such notice by 
the Company, the Company shall, subject to the provisions of Section 8 hereof 
and Section 5 of the Warrant, cause to be registered under the Act all of the 
Registrable Securities that each such Holder has requested to be registered.

          3.  DEMAND REGISTRATION.  In case the Company shall, at any time 
before October 15, 2002, receive from Holders holding 40% or more of the 
outstanding Registrable Securities a written request (to be exercised only 
once) that the Company effect a registration 

<PAGE>

and any related qualification or compliance with respect to all or a part of 
the Registrable Securities (which registration shall at the election of 
Holder either be for a registration for a primary issuance of the Shares upon 
the exercise of the Warrant or the resale of the Shares previously issued 
upon exercise of the Warrant at the election of Holder) owned by such Holder, 
the Company will promptly notify each other Holder (if any) of such request 
and will:

              (a)  as soon as practicable, effect such registration and all 
such qualifications and compliances as may be so requested and as would 
permit or facilitate the sale and distribution of all or such portion of a 
Holder's Registrable Securities as are specified in such request, together 
with all or such portion of the Registrable Securities of any other holder of 
registration rights joining in such request as are specified in a written 
request given within 20 days after receipt of such written notice from the 
Company; PROVIDED, HOWEVER, that the Company shall not be obligated to effect 
any such registration, qualification or compliance, pursuant to this Section 
3:  (1) if the Company has effected a registration of Registrable Securities 
pursuant to this Section 3 within the preceding 12 months; (2) if the Company 
shall furnish to Holder a certificate signed by the President of the Company 
stating that in the good faith judgment of the Board of Directors of the 
Company, it would be seriously detrimental to the Company and its 
stockholders for such registration to be effected at such time, in which 
event the Company shall have the right to defer the filing of the 
registration statement for a period of not more than 60 days after receipt of 
the request of Holder under this Section 3; PROVIDED, HOWEVER, that the 
Company shall not utilize this right more than once in any twelve-month 
period; or (3) in any jurisdiction in which the Company would be required to 
qualify to do business or to execute a general consent to service of process 
in effecting such registration, qualification or compliance; and,
                
              (b)  subject to the foregoing, file a registration statement 
covering the Registrable Securities and other securities so requested to be 
registered promptly after receipt of the request or requests of Holder, and 
in any event within 30 days of receipt of such request.
                                        
          4.  OBLIGATION OF THE COMPANY.  Subject to the terms of the 
Warrant, in the event that the Company is to effect the registration of any 
Registrable Securities pursuant to Section 2 or 3 hereof, the Company shall 
promptly:

              (a)  Prepare and file with the SEC a registration statement 
with respect to such Registrable Securities and use its best efforts to cause 
such registration statement to become effective, and, upon the request of the 
holders of a majority of the securities registered thereunder, keep such 
registration statement effective for up to one hundred twenty (120) days, or 
such shorter period as is required to dispose of all securities covered by 
such registration statement.

              (b)  Prepare and file with the SEC such amendments and 
supplements to such registration statement and the prospectus used in 
connection with such registration statement as may be necessary to comply 
with the provisions of the Act with respect to the disposition of all 
securities covered by such registration statement.

                                       2
<PAGE>

              (c)  Furnish to Holder such number of copies of a prospectus, 
including a preliminary prospectus, in conformity with the requirements of 
the Act, and such other documents as Holder may reasonably request in order 
to facilitate the disposition of Registrable Securities owned by Holder.
                     
              (d)  Use its best efforts to register and qualify the 
securities covered by such registration statement under such other securities 
or Blue Sky laws of such jurisdictions as shall be reasonably requested by 
Holder, provided that the Company shall not be required in connection 
therewith or as a condition thereto to qualify to do business or to file a 
general consent to service of process in any such states or jurisdictions or 
to agree to any restrictions as to the conduct of its business in the 
ordinary course thereof.
                                        
              (e)  In the event of any underwritten public offering, enter 
into and perform its obligations under an underwriting agreement, in usual 
and customary form, with the managing underwriter of such offering.  Holder 
shall also enter into and perform its obligations under such underwriting 
agreement.
                                        
              (f)  Notify Holder at any time when a prospectus relating to 
Registrable Securities of Holder covered by such registration statement is 
required to be delivered under the Act, of the happening of any event as a 
result of which the prospectus included in such registration statement, as 
then in effect, includes an untrue statement of a material fact or omits to 
state a material fact required to be stated therein or necessary to make the 
statements therein not misleading in the light of the circumstances under 
which they were made.
                                        
              (g)  Furnish, at the request of Holder, on the date that such 
Registrable Securities are delivered to the underwriters for sale in 
connection with a registration pursuant to the Warrant, if such securities 
are being sold through underwriters, or, if such securities are not being 
sold through underwriters, on the date that the registration statement with 
respect to such securities becomes effective, (i) an opinion, dated such 
date, of counsel representing the Company for the purposes of such 
registration, in form and substance as is customarily given to underwriters 
in an underwritten public offering, addressed to the underwriters, if any, 
and to Holder and (ii) a letter dated such date, from the independent 
certified public accountants of the Company, in form and substance as is 
customarily given by independent certified public accountants to underwriters 
in an underwritten public offering, addressed to the underwriters, if any, 
and to Holder.

          5.  AVAILABILITY OF RULE 144.  Notwithstanding anything in the 
Warrant or this Statement of Registration Rights to the contrary, the Company 
shall not be obligated to effect any such registration, qualification or 
compliance, pursuant to Section 2 or 3, if application of Rule 144 would 
allow Holder requesting a registration under Section 2 or 3 to dispose of the 
Registrable Securities for which a registration is demanded within a single 
90-day period.

                                       3
<PAGE>

          6.  FURNISH INFORMATION.  It shall be a condition precedent to the 
obligations of the Company to take any action pursuant to the Warrant that 
the selling Holder shall furnish to the Company such information regarding 
itself, the Registrable Securities held by Holder, and the intended method of 
disposition of such securities as shall be required to effect the 
registration of their Registrable Securities.

          7.  EXPENSES.  The Company shall bear and pay all expenses (other 
than underwriting discounts and commissions) incurred in connection with any 
registration, filing or qualification of Registrable Securities, including 
(without limitation) all registration, filing, and qualification fees, legal, 
printers and accounting fees relating thereto, and the cost of any reasonable 
fees or disbursements of counsel for Holder.

          8.  UNDERWRITING REQUIREMENTS.  In connection with any 
registrations in which Registrable Securities have a right to be included 
pursuant to Section 2 hereof and which involves an underwriting of securities 
being issued by the Company, the Company shall not be required, under Section 
2 hereof, to include any of Holder's securities in such underwriting unless 
Holder accepts the terms of the underwriting as agreed upon between the 
Company and the underwriters selected by it, and then only in such quantity 
as will not, in the opinion of the underwriters, jeopardize the success of 
the offering by the Company.  If the total amount of securities, including 
Registrable Securities, requested by stockholders to be included in such 
offering exceeds the amount of securities sold other than by the Company that 
the underwriters reasonably believe compatible with the success of the 
offering, then the Company shall be required to include in the offering only 
that number of such securities, including Registrable Securities, which the 
underwriters believe will not jeopardize the success of the offering, the 
securities so included to be apportioned pro rata among the selling Holder 
and other shareholders holding contractual registration rights according to 
the total amount of securities entitled to be included herein owned by each 
selling stockholder or in such other proportions as shall mutually be agreed 
to by Holder and each other selling stockholder.

          9.  INDEMNIFICATION.  In the event any Registrable Securities are 
included n a registration statement filed by the Company:

              (a)  The Company will indemnify and holder harmless Holder, its 
officers, directors, and agents, any underwriter (as defined in the Act) for 
Holder and each person, if any, who controls Holder or underwriter within the 
meaning of the Act or the Securities Exchange Act of 1934, as amended (the 
"1934 Act"), against any losses, claims, damages, or liabilities (joint or 
several) asserted by a third party to which they may become subject under the 
Act, the 1934 Act or other federal or state law, insofar as such losses, 
claims, damages, or liabilities (or actions in respect thereof) arise out of 
or are based upon any of the following statements, omissions or violations 
(collectively a "Violation"):  (i) any untrue statement or alleged untrue 
statement of a material fact contained in such registration statement, 
including any preliminary prospectus or final prospectus contained therein or 
any amendments or supplements thereto, (ii) the omission or alleged omission 
to state therein a material fact required to be stated therein, or necessary 
to make the statements therein not misleading, or (iii) any violation or 
alleged violation of the Company of the Act, the 1934 Act, any state 

                                       4
<PAGE>

securities law or any rule or regulation promulgated under the Act, the 1934 
Act or any state securities law; and the Company will reimburse Holder, any 
of its officers or directors, underwriter or controlling person for any legal 
or other expenses reasonably incurred by them, as incurred, in connection 
with investigating or defending any such loss, claim, damage, liability, or 
action; PROVIDED, HOWEVER, that the indemnity agreement contained in this 
Section 9(a) shall not apply to amounts paid in settlement of any such loss, 
claim, damage, liability or action if such settlement is effected without the 
consent of the Company (which consent shall not be unreasonably withheld), 
nor shall the Company be liable in any such case for any such loss, claim, 
damage, liability, or action to the extent that it arises out of or is based 
upon a Violation which occurs in reliance upon and in conformity with written 
information furnished expressly for use in connection with such registration 
by such Holder, underwriter or controlling person.
                                        
              (b)  Holder will indemnify and hold harmless the Company, each 
of its directors, each of its officers who have signed the registration 
statement, each person, if any, who controls the Company with the meaning of 
the Act, any underwriter and any other shareholder selling securities in such 
registration statement or any of its directors or officers or any person who 
controls such shareholder, against any losses, claims, damages, or 
liabilities (joint or several) asserted by a third party to which the Company 
or any such director, officer, controlling person, or underwriter or 
controlling person, or other such shareholder or director, officer or 
controlling person may become subject, under the Act, the 1934 Act or other 
federal or state law, insofar as such losses, claims, damages, or liabilities 
(or actions in respect thereto) arise out of or are based upon any Violation, 
in each case to the extent (and only to the extent) that such Violation 
occurs in reliance upon and in conformity with written information furnished 
by Holder expressly for use in connection with such registration; and Holder 
will reimburse any legal or other expenses reasonably incurred by the Company 
or any such director, officer, controlling person, underwriter or controlling 
person, other shareholder, officer, director, or controlling person, as 
incurred, in connection with investigating or defending any such loss, claim, 
damage, liability, or action; PROVIDED, HOWEVER, that the obligations of 
Holder hereunder shall be limited to an amount equal to the net proceeds 
(equal to the offering price less the exercise price, expenses and 
underwriting commissions and discounts) to such Holder of Shares sold as 
contemplated herein.  Notwithstanding the foregoing, the indemnity agreement 
contained in this Section 9(b) shall not apply to amounts paid in settlement 
of any such loss, claim, damage, liability or action if such settlement is 
effected without the consent of Holder, which consent shall not be 
unreasonably withheld.
                                        
              (c)  Promptly after receipt by an indemnified party under this 
Section 9 of notice of the commencement of any action (including any 
governmental action), such indemnified party will, if a claim in respect 
thereof is to be made against any indemnifying part under this Section 9, 
deliver to the indemnifying party a written notice of the commencement 
thereof and the indemnifying party shall have the right to participate in, 
and, to the extent the indemnifying party so desires, jointly with any other 
indemnifying party similarly noticed, to assume the defense thereof with 
counsel mutually satisfactory to the parties; PROVIDED, HOWEVER, that an 
indemnified party shall have the right to retain its

                                       5
<PAGE>

own counsel, with the fees and expenses to be paid by the  indemnifying 
party, if representation of such indemnified party by the counsel retained by 
the indemnifying party would be inappropriate due to actual or potential 
differing interests between such indemnified party and any other party 
represented by such counsel in such proceeding.  The failure to deliver 
written notice to the indemnifying party within a reasonable time of the 
commencement of any such action, if prejudicial to its ability to  defend 
such action, shall relieve such indemnifying party of any liability to  the 
indemnified party under this Section 9, but the omission so to deliver  
written notice to the indemnifying party will not relieve it of any liability 
that it may have to any indemnified party otherwise than under this Section 9.

          10. REPORTS UNDER THE 1934 ACT.  With a view to making available to 
Holder the benefits of Rule 144 promulgated under the Act and any other rule 
or regulation of the SEC that may at any time permit Holder to sell 
securities of the Company to the public without registration the Company will 
endeavor to:

              (a)  make and keep public information available, as those terms 
are understood and defined in SEC Rule 144;
                                        
              (b)  take such action as is necessary to enable Holder to 
utilize an abbreviated registration statement for the sale of its Registrable 
Securities;
                                        
              (c)  file with the SEC in a timely manner all reports and other 
documents required of the Company under the Act and the 1934 Act; and
                                        
              (d)  furnish to Holder, so long as Holder owns any Registrable 
Securities, forthwith upon request (i) a written statement by the Company 
that it has complied with the reporting requirements of SEC Rule 144, the Act 
and the 1934 Act, or that it qualifies as a registrant whose securities may 
be resold pursuant to Form S-3 (at any time after it so qualifies), (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 in availing Holder of any rule or 
regulation of the SEC which permits the selling of any such securities 
without registration or pursuant to such form.

          11. ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause the 
Company to register Registrable Securities pursuant to the Warrant may be 
assigned by Holder to a permitted transferee or assignee of the Warrant of at 
least 150,000 Shares, provided the Company is, within a reasonable time after 
such transfer, furnished with written notice of the name and address of such 
transferee or assignee and the securities with respect to which such 
registration rights are being assigned; and provided, further, that such 
assignment shall be effective only if immediately following such transfer the 
further disposition of such securities by the transferee or assignee is 
restricted under the Act.

    5.   ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES.  The number of
Shares issuable upon the exercise of this Warrant and the Warrant Price shall be
subject to adjustment from time to time upon the occurrence of certain events,
as follows:

         (a)  ADJUSTMENT FOR DIVIDENDS IN STOCK.  In case at any time or from
time to time on or after the date hereof the holders of the Common Stock of the
Company (or any shares of stock or other securities at the time receivable upon
the exercise of this Warrant) shall have received or, on or after the record
date fixed for the determination of eligible stockholders, shall have become
entitled to receive, without payment therefor, other or additional stock of the
Company by way of dividend then, and in each case, the Holder of this Warrant
shall, upon the exercise hereof, be entitled to receive, in addition to the
number of shares of Common Stock receivable thereupon, and without payment of
any additional  consideration therefor, the amount of such other or additional
stock of the Company which such Holder would hold on the date of such exercise
had it been the holder of record of such Common Stock on the date hereof and had
thereafter, during the period from the date hereof to and including the date of
such exercise, retained such shares and/or all other additional stock receivable
by it as aforesaid during such period, giving effect to all adjustments called
for during such period by paragraphs (b) and (c) of this Section 5.

         (b)  ADJUSTMENT FOR RECLASSIFICATION OR REORGANIZATION.  In case of
any reclassification or change of the outstanding securities of the Company or
of any consolidation, merger or reorganization of the Company on or after the
date hereof, then and in each such case the Holder of this Warrant, upon the
exercise hereof at any time after the consummation of such reclassification,
change, consolidation, merger or reorganization, shall be entitled to receive,
in lieu of or in addition to the stock or other securities and property
receivable upon the exercise hereof prior to such consummation, the stock or
other securities to which such Holder would have been entitled upon such
consummation if such Holder had exercised this Warrant immediately prior
thereto, all subject to further adjustment as provided in subparagraphs (a) and
(c); in each such case, the terms of this Paragraph 5 shall be applicable to the
shares of stock or other securities property receivable upon the exercise of
this Warrant after such consummation.

         (c)  STOCK SPLITS AND REVERSE STOCK SPLITS.  If, at any time on or
after the date hereof, the Company shall subdivide its outstanding shares of
Common Stock into a greater number of shares, the Warrant Price in effect
immediately prior to such subdivision shall thereby be proportionately reduced
and the number of shares receivable upon exercise of this Warrant shall thereby
be proportionately increased; and, conversely, if at any time on or after the
date hereof the outstanding number of shares of Common Stock shall be combined
into a smaller number of shares, the Warrant Price in effect immediately prior
to such combination shall thereby be proportionately increased and the number of
shares receivable upon exercise of the Warrant shall be proportionately
decreased.

         (d)  ADJUSTMENTS TO WARRANT PRICE.  Whenever the number of Shares
purchasable upon exercise of this Warrant is adjusted, as herein provided, the
Warrant Price shall be adjusted by multiplying the Exercise Price in effect
immediately prior to such

                                       4
<PAGE>

adjustment by a fraction, of which the numerator shall be the number of 
Shares purchasable upon the exercise of each Warrant immediately prior to 
such adjustment, and of which the denominator shall be the number of Shares 
so purchasable immediately thereafter.

         (e)  CERTIFICATES AS TO ADJUSTMENTS.  Upon each adjustment of the
Warrant Price, the Company at its expense shall promptly compute such
adjustment, and furnish the Holder with a certificate of its Chief Financial
Officer setting forth such adjustment and the facts upon which such adjustment
is based.  The Company shall, upon written request, furnish the Holder a
certificate setting forth the Warrant Price in effect upon the date thereof and
the series of adjustments leading to such Warrant Price.

    6.   ACQUISITIONS.

         (a)  ASSUMPTION OF WARRANT.  If upon the closing of any Acquisition
the successor entity assumes the obligations of this Warrant, then this Warrant
shall be exercisable for the same securities, cash, and property as would be
payable for the Shares issuable upon exercise of the unexercised portion of this
Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing.

         (b)  NONASSUMPTION.  If upon the closing of any Acquisition the
successor entity does not assume the obligations of this Warrant and the Holder
has not otherwise exercised this Warrant in full, then the unexercised portion
of this Warrant shall be deemed to have been automatically converted pursuant to
Section 4(c) and thereafter the Holder shall participate in the acquisition on
the same terms as other holders of the same class of securities of the Company.

    7.   NOTICES; INFORMATION; REGISTRATION.

         (a)  NOTICE OF CERTAIN EVENTS.  If the Company proposes at any time
(a) to effect any reclassification or recapitalization of Common Stock; (b) to
merge or consolidate with or into any other corporation, or sell, lease,
license, or convey all or substantially all of its assets, or to liquidate,
dissolve or wind up; or (c) offer holders of registration rights the opportunity
to participate in an underwritten public offering of the company's securities
for cash, then, in connection with each such event, the Company shall give the
Holder at least 14 days prior written notice of the date on which a record will
be taken for such action.  

         (b)  INFORMATION RIGHTS.  So long as the Holder holds this Warrant
and/or any of the Shares, the Company shall deliver to the Holder (a) promptly
after mailing, copies of all notices or other written communications to the
stockholders of the Company, (b) within ninety days after the end of each fiscal
year of the Company, the annual audited financial statements of the Company
audited by independent public accountants of recognized standing and (c) within
forty-five days after the end of each of the first three quarters of each fiscal
year, the Company's quarterly, unaudited financial statements.

                                       5
<PAGE>

         (c)  REGISTRATION UNDER SECURITIES ACT OF 1933.  The Company agrees
that the Shares shall be subject to the registration rights set forth on
Exhibit B.

    8.   COMPLIANCE WITH ACT; TRANSFERABILITY AND NEGOTIABILITY OF WARRANT;
         DISPOSITION OF SHARES.

         (a)  COMPLIANCE WITH ACT.  The Holder, by acceptance hereof, agrees
that this Warrant and the Shares to be issued upon the exercise hereof are being
acquired solely for its own account and not as a nominee for any other party and
not with a view toward the resale or distribution thereof and that it will not
offer, sell or otherwise dispose of this Warrant or any Shares to be issued upon
the exercise hereof except under circumstances which will not result in a
violation of the Act.  This Warrant and the Shares to be issued upon the
exercise hereof (unless registered under the Act) shall be imprinted with a
legend in substantially the following form:
         
    THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
    SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED,
    ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION
    STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN
    ACCORDANCE WITH RULE 144 UNDER THE ACT, OR THE COMPANY RECEIVES AN
    OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY
    SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER,
    ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND
    PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

In addition, this Warrant and the Shares to be issued upon the exercise hereof
shall bear any legends required by the securities laws of any applicable states.

         (b)  TRANSFERABILITY AND NEGOTIABILITY OF WARRANT.  This Warrant may
not be transferred or assigned in whole or in part without compliance with all
applicable federal and state securities laws by the transferor and the
transferee (including the delivery of investment representation letters and
legal opinions satisfactory to the Company, if requested by the Company and the
transfer is to a person other than a general partner or affiliate of the initial
Holder).  Subject to the provisions of this Warrant with respect to compliance
with the Act, title to this Warrant may be transferred by endorsement and
delivery in the same manner as a negotiable instrument transferable by
endorsement and delivery.  The Company shall act promptly to record transfers of
this Warrant on its books, but the Company may treat the registered holder of
this Warrant as the absolute owner of this Warrant for all purposes,
notwithstanding any notice to the contrary.

                                       6
<PAGE>

         (c)  DISPOSITION OF SHARES.  With respect to any offer, sale, transfer
or other disposition of any Shares acquired pursuant to the exercise of this
Warrant prior to registration of such Shares, except for any such offer, sale,
transfer or other disposition of Shares to an affiliate of the initial Holder,
the Holder and each subsequent holder of this Warrant agrees to give written
notice to the Company prior thereto, describing briefly the manner thereof, and
if such transfer is not pursuant to Rule 144, a written opinion of legal counsel
for such holder, if requested by the Company, to the effect that such offer,
sale or other disposition may be effected without registration or qualification
of such Shares.  Notwithstanding the foregoing, such Shares may be offered, sold
or otherwise disposed of in accordance with Rule 144, provided that the Company
shall have been furnished with such information as the Company may reasonably
request to provide a reasonable assurance that the provisions of Rule 144 have
been satisfied.  Each certificate representing the Shares thus transferred
(except a transfer pursuant to Rule 144) shall bear a restrictive legend as to
the applicable restrictions on transferability in order to insure compliance
with the Act, unless in the aforesaid opinion of legal counsel for the holder,
such legend is not required in order to insure compliance with the Act.

    9.   RIGHTS OF STOCKHOLDERS.  No Holder shall be entitled to vote or
receive dividends or be deemed the holder of Shares or any other securities of
the Company which may at any time be issuable on the exercise of this Warrant
for any purpose, nor shall anything contained herein be construed to confer upon
the Holder, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action (whether upon any recapitalization, issuance of stock,
reclassification of stock, consolidation, merger, transfer of assets or
otherwise) or, except as expressly required herein, to receive notice of
meetings, or to receive dividends or subscription rights or otherwise until this
Warrant shall have been exercised and the Shares issuable upon exercise hereof
shall have become deliverable, as provided herein.

    10.  REPLACEMENT OF WARRANTS.  On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, on surrender and  cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

    11.  EXCHANGE OF WARRANT.  Subject to the other provisions of this Warrant,

                        STATEMENT OF REGISTRATION RIGHTS



    1.   DEFINITIONS.  For purposes of the Warrant to which this Statement of
Registration Rights is attached as Exhibit B:

         (a)  The terms "register," "registered," and "registration" refer to a
registration effected by preparing and filing a registration statement or
similar document in compliance with the Securities Act of 1933, as amended (the
"Act"), and the declaration or ordering of effectiveness of such registration
statement or document;

         (b)  The term "Registrable Securities" means the shares of Common
Stock issued or issuable upon exercise of the Warrant;

         (c)  The term "Holder" means the original holder of the Warrant and
any transferee of the Warrant; and

         (d)  The term "Warrant" means the original Warrants issued in
connection with the Stock and Warrant Purchase Agreement, dated as of
October 15, 1997, between the Company, as Seller, and Wexford Spectrum Investors
LLC, a Delaware limited liability company, and Imprimis Investors LLC, a
Delaware limited liability company, as Buyers, and all Warrants issued as a
result of the transfer of such original Warrants.

    2.   COMPANY REGISTRATION.  If (but without any obligation to do so) the 
Company proposes at any time before October 15, 2002 to register (including 
for this purpose a registration effected by the Company for stockholders 
other than Holder) any of its stock or other securities under the Act in 
connection with the public offering for its own account of such securities 
solely for cash (other than a registration relating solely to the sale of 
securities to participants in a Company stock plan, or a registration on any 
form which does not include substantially the same information as would be 
required to be included in a registration statement covering the sale of the 
Registrable Securities), the Company shall, at such time, promptly give 
Holder written notice of such registration.  Upon the written request of 
Holder given within twenty days after mailing of such notice by the Company, 
the Company shall, subject to the provisions of Section 8 hereof and Section 
5 of the Warrant, cause to be registered under the Act all of the Registrable 
Securities that each such Holder has requested to be registered.

    3.   DEMAND REGISTRATION.  In case the Company shall, at any time before
October 15, 2002, receive from Holders holding 40% or more of the outstanding
Registrable Securities a written request (to be exercised only once) that the
Company effect a registration

<PAGE>

and any related qualification or compliance with respect to all or a 
part of the Registrable Securities (which registration shall at the election 
of Holder either be for a registration for a primary issuance of the Shares 
upon the exercise of the Warrant or the resale of the Shares previously 
issued upon exercise of the Warrant at the election of Holder) owned by such 
Holder, the Company will promptly notify each other Holder (if any) of such 
request and will:

         (a)  as soon as practicable, effect such registration and all such 
qualifications and compliances as may be so requested and as would permit or 
facilitate the sale and distribution of all or such portion of a Holder's 
Registrable Securities as are specified in such request, together with all or 
such portion of the Registrable Securities of any other holder of 
registration rights joining in such request as are specified in a written 
request given within 20 days after receipt of such written notice from the 
Company; PROVIDED, HOWEVER, that the Company shall not be obligated to effect 
any such registration, qualification or compliance, pursuant to this Section 
3:  (1) if the Company has effected a registration of Registrable Securities 
pursuant to this Section 3 within the preceding 12 months; (2) if the Company 
shall furnish to Holder a certificate signed by the President of the Company 
stating that in the good faith judgment of the Board of Directors of the 
Company, it would be seriously detrimental to the Company and its 
stockholders for such registration to be effected at such time, in which 
event the Company shall have the right to defer the filing of the 
registration statement for a period of not more than 60 days after receipt of 
the request of Holder under this Section 3; PROVIDED, HOWEVER, that the 
Company shall not utilize this right more than once in any twelve-month 
period; or (3) in any jurisdiction in which the Company would be required to 
qualify to do business or to execute a general consent to service of process 
in effecting such registration, qualification or compliance; and,

         (b)  subject to the foregoing, file a registration statement covering
the Registrable Securities and other securities so requested to be registered
promptly after receipt of the request or requests of Holder, and in any event
within 30 days of receipt of such request.

    4.   OBLIGATION OF THE COMPANY.  Subject to the terms of the Warrant, in
the event that the Company is to effect the registration of any Registrable
Securities pursuant to Section 2 or 3 hereof, the Company shall promptly:

         (a)  Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of the holders
of a majority of the securities registered thereunder, keep such registration
statement effective for up to one hundred twenty (120) days, or such shorter
period as is required to dispose of all securities covered by such registration
statement.

         (b)  Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

                                       2
<PAGE>

         (c)  Furnish to Holder such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Act, and such other documents as Holder may reasonably request in order to
facilitate the disposition of Registrable Securities owned by Holder.

         (d)  Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by Holder, provided
that the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such states or jurisdictions or to agree to any restrictions as
to the conduct of its business in the ordinary course thereof.

         (e)  In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering.  Holder shall also enter
into and perform its obligations under such underwriting agreement.

         (f)  Notify Holder at any time when a prospectus relating to
Registrable Securities of Holder covered by such registration statement is
required to be delivered under the Act, of the happening of any event as a
result of which the prospectus included in such registration statement, as then
in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances under which they were
made.

         (g)  Furnish, at the request of Holder, on the date that such
Registrable Securities are delivered to the underwriters for sale in connection
with a registration pursuant to the Warrant, if such securities are being sold
through underwriters, or, if such securities are not being sold through
underwriters, on the date that the registration statement with respect to such
securities becomes effective, (i) an opinion, dated such date, of counsel
representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and to Holder and (ii) a letter
dated such date, from the independent certified public accountants of the
Company, in form and substance as is customarily given by independent certified
public accountants to underwriters in an underwritten public offering, addressed
to the underwriters, if any, and to Holder.

    5.   AVAILABILITY OF RULE 144.  Notwithstanding anything in the Warrant or
this Statement of Registration Rights to the contrary, the Company shall not be
obligated to effect any such registration, qualification or compliance, pursuant
to Section 2 or 3, if application of Rule 144 would allow Holder requesting a
registration under Section 2 or 3 to dispose of the Registrable Securities for
which a registration is demanded within a single 90-day period.

                                       3
<PAGE>

    6.   FURNISH INFORMATION.  It shall be a condition precedent to the
obligations of the Company to take any action pursuant to the Warrant that the
selling Holder shall furnish to the Company such information regarding itself,
the Registrable Securities held by Holder, and the intended method of
disposition of such securities as shall be required to effect the registration
of their Registrable Securities.

    7.   EXPENSES.  The Company shall bear and pay all expenses (other than
underwriting discounts and commissions) incurred in connection with any
registration, filing or qualification of Registrable Securities, including
(without limitation) all registration, filing, and qualification fees, legal,
printers and accounting fees relating thereto, and the cost of any reasonable
fees or disbursements of counsel for Holder.

    8.   UNDERWRITING REQUIREMENTS.  In connection with any registrations in
which Registrable Securities have a right to be included pursuant to Section 2
hereof and which involves an underwriting of securities being issued by the
Company, the Company shall not be required, under Section 2 hereof, to include
any of Holder's securities in such underwriting unless Holder accepts the terms
of the underwriting as agreed upon between the Company and the underwriters
selected by it, and then only in such quantity as will not, in the opinion of
the underwriters, jeopardize the success of the offering by the Company.  If the
total amount of securities, including Registrable Securities, requested by
stockholders to be included in such offering exceeds the amount of securities
sold other than by the Company that the underwriters reasonably believe
compatible with the success of the offering, then the Company shall be required
to include in the offering only that number of such securities, including
Registrable Securities, which the underwriters believe will not jeopardize the
success of the offering, the securities so included to be apportioned pro rata
among the selling Holder and other shareholders holding contractual registration
rights according to the total amount of securities entitled to be included
herein owned by each selling stockholder or in such other proportions as shall
mutually be agreed to by Holder and each other selling stockholder.

    9.   INDEMNIFICATION.  In the event any Registrable Securities are included
n a registration statement filed by the Company:

         (a)  The Company will indemnify and holder harmless Holder, its
officers, directors, and agents, any underwriter (as defined in the Act) for
Holder and each person, if any, who controls Holder or underwriter within the
meaning of the Act or the Securities Exchange Act of 1934, as amended (the "1934
Act"), against any losses, claims, damages, or liabilities (joint or several)
asserted by a third party to which they may become subject under the Act, the
1934 Act or other federal or state law, insofar as such losses, claims, damages,
or liabilities (or actions in respect thereof) arise out of or are based upon
any of the following statements, omissions or violations (collectively a
"Violation"):  (i) any untrue statement or alleged untrue statement of a
material fact contained in such registration statement, including any
preliminary prospectus or final prospectus contained therein or any amendments
or supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading, or (iii) any violation or alleged violation of the
Company of the Act, the 1934 Act, any state

                                       4
<PAGE>

securities law or any rule or regulation promulgated under the Act, the 1934 
Act or any state securities law; and the Company will reimburse Holder, any 
of its officers or directors, underwriter or controlling person for any legal 
or other expenses reasonably incurred by them, as incurred, in connection 
with investigating or defending any such loss, claim, damage, liability, or 
action; PROVIDED, HOWEVER, that the indemnity agreement contained in this 
Section 9(a) shall not apply to amounts paid in settlement of any such loss, 
claim, damage, liability or action if such settlement is effected without the 
consent of the Company (which consent shall not be unreasonably withheld), 
nor shall the Company be liable in any such case for any such loss, claim, 
damage, liability, or action to the extent that it arises out of or is based 
upon a Violation which occurs in reliance upon and in conformity with written 
information furnished expressly for use in connection with such registration 
by such Holder, underwriter or controlling person.

         (b)  Holder will indemnify and hold harmless the Company, each of its
directors, each of its officers who have signed the registration statement, each
person, if any, who controls the Company with the meaning of the Act, any
underwriter and any other shareholder selling securities in such registration
statement or any of its directors or officers or any person who controls such
shareholder, against any losses, claims, damages, or liabilities (joint or
several) asserted by a third party to which the Company or any such director,
officer, controlling person, or underwriter or controlling person, or other such
shareholder or director, officer or controlling person may become subject, under
the Act, the 1934 Act or other federal or state law, insofar as such losses,
claims, damages, or liabilities (or actions in respect thereto) arise out of or
are based upon any Violation, in each case to the extent (and only to the
extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by Holder expressly for use in connection with
such registration; and Holder will reimburse any legal or other expenses
reasonably incurred by the Company or any such director, officer, controlling
person, underwriter or controlling person, other shareholder, officer, director,
or controlling person, as incurred, in connection with investigating or
defending any such loss, claim, damage, liability, or action; PROVIDED, HOWEVER,
that the obligations of Holder hereunder shall be limited to an amount equal to
the net proceeds (equal to the offering price less the exercise price, expenses
and underwriting commissions and discounts) to such Holder of Shares sold as
contemplated herein.  Notwithstanding the foregoing, the indemnity agreement
contained in this Section 9(b) shall not apply to amounts paid in settlement of
any such loss, claim, damage, liability or action if such settlement is effected
without the consent of Holder, which consent shall not be unreasonably withheld.

         (c)  Promptly after receipt by an indemnified party under this
Section 9 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying part under this Section 9, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; PROVIDED, HOWEVER, that an indemnified party shall
have the right to  retain its

                                       5
<PAGE>

own counsel, with the fees and expenses to be paid by the  indemnifying 
party, if representation of such indemnified party by the counsel retained by 
the indemnifying party would be inappropriate due to actual or potential 
differing interests between such indemnified party and any other party 
represented by such counsel in such proceeding.  The failure to deliver 
written notice to the indemnifying party within a reasonable time of the 
commencement of any such action, if prejudicial to its ability to  defend 
such action, shall relieve such indemnifying party of any liability to  the 
indemnified party under this Section 9, but the omission so to deliver  
written notice to the indemnifying party will not relieve it of any liability 
that it may have to any indemnified party otherwise than under this Section 9.

    10.  REPORTS UNDER THE 1934 ACT.  With a view to making available to Holder
the benefits of Rule 144 promulgated under the Act and any other rule or
regulation of the SEC that may at any time permit Holder to sell securities of
the Company to the public without registration the Company will endeavor to:

         (a)  make and keep public information available, as those terms are
understood and defined in SEC Rule 144;
         
         (b)  take such action as is necessary to enable Holder to utilize an
abbreviated registration statement for the sale of its Registrable Securities;
         
         (c)  file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and
         
         (d)  furnish to Holder, so long as Holder owns any Registrable
Securities, forthwith upon request (i) a written statement by the Company that
it has complied with the reporting requirements of SEC Rule 144, the Act and the
1934 Act, or that it qualifies as a registrant whose securities may be resold
pursuant to Form S-3 (at any time after it so qualifies), (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 in availing Holder of any rule or regulation of the SEC
which permits the selling of any such securities without registration or
pursuant to such form.

    11.  ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause the Company to
register Registrable Securities pursuant to the Warrant may be assigned by
Holder to a permitted transferee or assignee of the Warrant of all 150,000
Shares, provided the Company is, within a reasonable time after such transfer,
furnished with written notice of the name and address of such transferee or
assignee and the securities with respect to which such registration rights are
being assigned; and provided, further, that such assignment shall be effective
only if immediately following such transfer the further disposition of such
securities by the transferee or assignee is restricted under the Act.

<PAGE>

delivered to the Holder within five days of delivery of the Notice of 
Exercise and, unless this Warrant has been fully exercised or has expired, a 
new warrant representing the portion of the Shares with respect to which this 
Warrant shall not then have been exercised shall also be issued to the Holder 
within such ten day period.

          (d)  NO FRACTIONAL SHARES.  No fractional shares shall be issued in
connection with any exercise hereunder, but in lieu of such fractional shares
the Company shall make a cash payment therefor upon the basis of the fair market
value per Share as of the date of exercise.

          (e)  COMPANY'S REPRESENTATIONS.

               (i)   The Company is soliciting proxies in connection with its 
Annual Meeting of Stockholders for, among other things, a proposal to amend 
its Certificate of Incorporation to increase the number of shares of Common 
Stock authorized for issuance.  If such proposal is approved by the Company's 
stockholders, the Company shall file a Certificate of Amendment to its 
Certificate of Incorporation with the Secretary of State of the State of 
Delaware (the "Amendment") in order to increase such number of authorized 
shares of Common Stock.  From and after the date of filing the Amendment, all 
Shares which may be issued upon the exercise of the purchase right 
represented by this Warrant shall, upon issuance, be duly authorized, validly 
issued, fully paid and non-assessable, and free of any liens and encumbrances 
except for restrictions on transfer under applicable federal and state 
securities laws.  From and after the date of the Amendment, during the period 
within which the purchase right represented by this Warrant may be exercised, 
the Company shall at all times use its best efforts to have authorized, and 
reserved for the purpose of issuance upon exercise of the purchase right 
represented by this Warrant, a sufficient number of Shares to provide for the 
exercise of the purchase right represented by this Warrant;

               (ii)  This Warrant has been duly authorized and executed by 
the Company and is a valid and binding obligation of the Company enforceable 
in accordance with its terms, subject to applicable bankruptcy, insolvency, 
reorganization, moratorium or other laws of general application affecting the 
enforcement of creditors' rights;

               (iii) The execution and delivery of this Warrant are not, and 
from and after the date of the Amendment, the issuance of the Shares upon 
exercise of this Warrant in accordance with the terms hereof will not be, 
inconsistent with the Company's Certificate of Incorporation or Bylaws, do 
not and will not contravene any law, governmental rule or regulation, 
judgment or order applicable to the Company, and do not and will not conflict 
with or contravene any provision of, or constitute a default under, any 
material indenture, mortgage, contract or other instrument of which the 
Company is a party or by which it is bound, or require the registration or 
filing with or the taking of any action in respect of or by, any federal, 
state or local government authority or agency (other than such consents, 
approvals, notices, actions, or filings as have already been obtained or 
made, as the case may be).

     5.   ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES.  The number of
Shares issuable upon the exercise of this Warrant and the Warrant Price shall be
subject to adjustment from time to time upon the occurrence of certain events,
as follows:

          (a)  ADJUSTMENT FOR DIVIDENDS IN STOCK.  In case at any time or from
time to time on or after the date hereof the holders of the Common Stock of the
Company (or any shares of stock or other securities at the time receivable upon
the exercise of this Warrant) shall have received or, on or after the record
date fixed for the determination of eligible stockholders, shall have become
entitled to receive, without payment therefor, other or additional stock of the
Company by way of dividend then, and in each case, the Holder of this Warrant
shall, upon the exercise hereof, be entitled to receive, in addition to the
number of shares of Common Stock receivable thereupon, and without payment of
any additional  consideration therefor, the amount of such other or additional
stock of the Company which such Holder would hold on the date of such exercise
had it been the holder of record of such Common Stock on the date hereof and had
thereafter, during the period from the date hereof to and including the date of
such exercise, retained such shares and/or all other additional stock receivable
by it as aforesaid during such period, giving effect to all adjustments called
for during such period by paragraphs (b) and (c) of this Section 5.
                    
          (b)  ADJUSTMENT FOR RECLASSIFICATION OR REORGANIZATION.  In case of
any reclassification or change of the outstanding securities of the Company or
of any consolidation, merger or reorganization of the Company on or after the
date hereof, then and in each such case the Holder of this Warrant, upon the
exercise hereof at any time after the consummation of such reclassification,
change, consolidation, merger or reorganization, shall be entitled to receive,
in lieu of or in addition to the stock or other securities and property
receivable upon the exercise hereof prior to such consummation, the stock or
other securities to which such Holder would have been entitled upon such
consummation if such Holder had exercised this Warrant immediately prior
thereto, all subject to further adjustment as provided in subparagraphs (a) and
(c); in each such case, the terms of this Paragraph 5 shall be applicable to the
shares of stock or other securities property receivable upon the exercise of
this Warrant after such consummation.
                    
          (c)  STOCK SPLITS AND REVERSE STOCK SPLITS.  If, at any time on or
after the date hereof, the Company shall subdivide its outstanding shares of
Common Stock into a greater number of shares, the Warrant Price in effect
immediately prior to such subdivision shall thereby be proportionately reduced
and the number of shares receivable upon exercise of this Warrant shall thereby
be proportionately increased; and, conversely, if at any time on or after the
date hereof the outstanding number of shares of Common Stock shall be combined
into a smaller number of shares, the Warrant Price in effect immediately prior
to such combination shall thereby be proportionately increased and the number of
shares receivable upon exercise of the Warrant shall be proportionately
decreased.
                    
          (d)  ADJUSTMENTS TO WARRANT PRICE.  Whenever the number of Shares
purchasable upon exercise of this Warrant is adjusted, as herein provided, the
Warrant Price shall be adjusted by multiplying the Exercise Price in effect
immediately prior to such

                                       4
<PAGE>

adjustment by a fraction, of which the numerator shall be the number of 
Shares purchasable upon the exercise of each Warrant immediately prior to 
such adjustment, and of which the denominator shall be the number of Shares 
so purchasable immediately thereafter.

          (e)  CERTIFICATES AS TO ADJUSTMENTS.  Upon each adjustment of the
Warrant Price, the Company at its expense shall promptly compute such
adjustment, and furnish the Holder with a certificate of its Chief Financial
Officer setting forth such adjustment and the facts upon which such adjustment
is based.  The Company shall, upon written request, furnish the Holder a
certificate setting forth the Warrant Price in effect upon the date thereof and
the series of adjustments leading to such Warrant Price.

     6.   ACQUISITIONS.

          (a)  ASSUMPTION OF WARRANT.  If upon the closing of any Acquisition
the successor entity assumes the obligations of this Warrant, then this Warrant
shall be exercisable for the same securities, cash, and property as would be
payable for the Shares issuable upon exercise of the unexercised portion of this
Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing.
                    
          (b)  NONASSUMPTION.  If upon the closing of any Acquisition the
successor entity does not assume the obligations of this Warrant and the Holder
has not otherwise exercised this Warrant in full, then the unexercised portion
of this Warrant shall be deemed to have been automatically converted pursuant to
Section 4(c) and thereafter the Holder shall participate in the acquisition on
the same terms as other holders of the same class of securities of the Company.

     7.   NOTICES; INFORMATION; REGISTRATION.

          (a)  NOTICE OF CERTAIN EVENTS.  If the Company proposes at any time
(a) to effect any reclassification or recapitalization of Common Stock; (b) to
merge or consolidate with or into any other corporation, or sell, lease,
license, or convey all or substantially all of its assets, or to liquidate,
dissolve or wind up; or (c) offer holders of registration rights the opportunity
to participate in an underwritten public offering of the company's securities
for cash, then, in connection with each such event, the Company shall give the
Holder at least 14 days prior written notice of the date on which a record will
be taken for such action.  
                    
          (b)  INFORMATION RIGHTS.  So long as the Holder holds this Warrant
and/or any of the Shares, the Company shall deliver to the Holder (a) promptly
after mailing, copies of all notices or other written communications to the
stockholders of the Company, (b) within ninety days after the end of each fiscal
year of the Company, the annual audited financial statements of the Company
audited by independent public accountants of recognized standing and (c) within
forty-five days after the end of each of the first three quarters of each fiscal
year, the Company's quarterly, unaudited financial statements.

                                       5
<PAGE>

          (c)  REGISTRATION UNDER SECURITIES ACT OF 1933.  The Company agrees
that the Shares shall be subject to the registration rights set forth on
Exhibit B.

     8.   COMPLIANCE WITH ACT; TRANSFERABILITY AND NEGOTIABILITY OF WARRANT;
               DISPOSITION OF SHARES.

          (a)  COMPLIANCE WITH ACT.  The Holder, by acceptance hereof, agrees
that this Warrant and the Shares to be issued upon the exercise hereof are being
acquired solely for its own account and not as a nominee for any other party and
not with a view toward the resale or distribution thereof and that it will not
offer, sell or otherwise dispose of this Warrant or any Shares to be issued upon
the exercise hereof except under circumstances which will not result in a
violation of the Act.  This Warrant and the Shares to be issued upon the
exercise hereof (unless registered under the Act) shall be imprinted with a
legend in substantially the following form:
                    
     THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
     SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED,
     ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION
     STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN
     ACCORDANCE WITH RULE 144 UNDER THE ACT, OR THE COMPANY RECEIVES AN
     OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY
     SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER,
     ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND
     PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

In addition, this Warrant and the Shares to be issued upon the exercise hereof
shall bear any legends required by the securities laws of any applicable states.

          (b)  TRANSFERABILITY AND NEGOTIABILITY OF WARRANT.  This Warrant may
not be transferred or assigned in whole or in part without compliance with all
applicable federal and state securities laws by the transferor and the
transferee (including the delivery of investment representation letters and
legal opinions satisfactory to the Company, if requested by the Company and the
transfer is to a person other than a general partner or affiliate of the initial
Holder).  Subject to the provisions of this Warrant with respect to compliance
with the Act, title to this Warrant may be transferred by endorsement and
delivery in the same manner as a negotiable instrument transferable by
endorsement and delivery.  The Company shall act promptly to record transfers of
this Warrant on its books, but the Company may treat the registered holder of
this Warrant as the absolute owner of this Warrant for all purposes,
notwithstanding any notice to the contrary.

                                       6
<PAGE>

          (c)  DISPOSITION OF SHARES.  With respect to any offer, sale, transfer
or other disposition of any Shares acquired pursuant to the exercise of this
Warrant prior to registration of such Shares, except for any such offer, sale,
transfer or other disposition of Shares to an affiliate of the initial Holder,
the Holder and each subsequent holder of this Warrant agrees to give written
notice to the Company prior thereto, describing briefly the manner thereof, and
if such transfer is not pursuant to Rule 144, a written opinion of legal counsel
for such holder, if requested by the Company, to the effect that such offer,
sale or other disposition may be effected without registration or qualification
of such Shares.  Notwithstanding the foregoing, such Shares may be offered, sold
or otherwise disposed of in accordance with Rule 144, provided that the Company
shall have been furnished with such information as the Company may reasonably
request to provide a reasonable assurance that the provisions of Rule 144 have
been satisfied.  Each certificate representing the Shares thus transferred
(except a transfer pursuant to Rule 144) shall bear a restrictive legend as to
the applicable restrictions on transferability in order to insure compliance
with the Act, unless in the aforesaid opinion of legal counsel for the holder,
such legend is not required in order to insure compliance with the Act.

     9.   RIGHTS OF STOCKHOLDERS.  No Holder shall be entitled to vote or
receive dividends or be deemed the holder of Shares or any other securities of
the Company which may at any time be issuable on the exercise of this Warrant
for any purpose, nor shall anything contained herein be construed to confer upon
the Holder, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action (whether upon any recapitalization, issuance of stock,
reclassification of stock, consolidation, merger, transfer of assets or
otherwise) or, except as expressly required herein, to receive notice of
meetings, or to receive dividends or subscription rights or otherwise until this
Warrant shall have been exercised and the Shares issuable upon exercise hereof
shall have become deliverable, as provided herein.

     10.  REPLACEMENT OF WARRANTS.  On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, on surrender and  cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

     11.  EXCHANGE OF WARRANT.  Subject to the other provisions of this Warrant,
on surrender of this Warrant for exchange, and subject to the provisions of this
Warrant with respect to compliance with the Act, the Company at its expense
shall issue to or on the order of the Holder a new warrant or warrants of like
tenor, in the name of the Holder or as the Holder (on payment by the Holder of
any applicable transfer taxes) may direct, for the number of Shares issuable
upon exercise thereof.

     12.  NOTICES.  All notices and other communications from the Company to the
Holder, or vice versa, shall be deemed delivered and effective when given
personally or

                                       7
<PAGE>

mailed by first-class registered or certified mail, postage prepaid, at such 
address as may have been furnished to the Company or the Holder, as the case 
may be, in writing by the Company or such Holder from time to time.

     13.  WAIVER.  This Warrant and any term hereof may be changed, waived,
discharged or terminated only by an instrument in writing signed by the party
against which enforcement of such change, waiver, discharge or termination is
sought.

     14.  GOVERNING LAW.  This Warrant shall be governed by and construed in
accordance with the laws of the State of Delaware.

     15.  TITLES AND SUBTITLES; FORMS OF PRONOUNS.  The titles of the Sections
and Subsections of this Warrant are for convenience only and are not to be
considered in construing this Warrant.  All pronouns used in this Warrant shall
be deemed to include masculine, feminine and neuter forms.
               
     16.  ATTORNEYS' FEES.  In the event of any dispute between the parties
concerning the terms and provisions of this Warrant, the party prevailing in
such dispute shall be entitled to collect from the other party all costs
incurred in such dispute, including reasonable attorneys' fees.

                           STATEMENT OF REGISTRATION RIGHTS
                                           


     1.   DEFINITIONS.  For purposes of the Warrant to which this Statement of
Registration Rights is attached as Exhibit B:

          (a)  The terms "register," "registered," and "registration" refer to a
registration effected by preparing and filing a registration statement or
similar document in compliance with the Securities Act of 1933, as amended (the
"Act"), and the declaration or ordering of effectiveness of such registration
statement or document;
                    
          (b)  The term "Registrable Securities" means the shares of Common
Stock issued or issuable upon exercise of the Warrant;
                    
          (c)  The term "Holder" means the original holder of the Warrant and
any transferee of the Warrant; and
                    
          (d)  The term "Warrant" means the original Warrants issued in
connection with the Stock and Warrant Purchase Agreement, dated as of
October 15, 1997, between the Company, as Seller, and Wexford Spectrum Investors
LLC, a Delaware limited liability company, and Imprimis Investors LLC, a
Delaware limited liability company, as Buyers, and all Warrants issued as a
result of the transfer of such original Warrants.

     2.   COMPANY REGISTRATION.  If (but without any obligation to do so) the
Company proposes at any time before October 15, 2002 to register (including for
this purpose a registration effected by the Company for stockholders other than
Holder) any of its stock or other securities under the Act in connection with
the public offering for its own account of such securities solely for cash
(other than a registration relating solely to the sale of securities to
participants in a Company stock plan, or a registration on any form which does
not include substantially the same information as would be required to be
included in a registration statement covering the sale of the Registrable
Securities), the Company shall, at such time, promptly give Holder written
notice of such registration.  Upon the written request of Holder given within
twenty days after mailing of such notice by the Company, the Company shall,
subject to the provisions of Section 8 hereof and Section 5 of the Warrant,
cause to be registered under the Act all of the Registrable Securities that each
such Holder has requested to be registered.

     3.   DEMAND REGISTRATION.  In case the Company shall, at any time before
October 15, 2002, receive from Holders holding 40% or more of the outstanding
Registrable Securities a written request (to be exercised only once) that the
Company effect a registration and any related qualification or compliance with
respect to all or a part of the Registrable Securities (which registration shall
at the election of Holder either be for a registration for a primary issuance of
the Shares upon the exercise of the Warrant or the resale of the Shares
previously issued upon exercise of the Warrant at the election of Holder) owned
by such Holder, the Company will promptly notify each other Holder (if any) of
such request and will:

<PAGE>

          (a)  as soon as practicable, effect such registration and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of a Holder's
Registrable Securities as are specified in such request, together with all or
such portion of the Registrable Securities of any other holder of registration
rights joining in such request as are specified in a written request given
within 20 days after receipt of such written notice from the Company; PROVIDED,
HOWEVER, that the Company shall not be obligated to effect any such
registration, qualification or compliance, pursuant to this Section 3:  (1) if
the Company has effected a registration of Registrable Securities pursuant to
this Section 3 within the preceding 12 months; (2) if the Company shall furnish
to Holder a certificate signed by the President of the Company stating that in
the good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its stockholders for such registration
to be effected at such time, in which event the Company shall have the right to
defer the filing of the registration statement for a period of not more than 60
days after receipt of the request of Holder under this Section 3; PROVIDED,
HOWEVER, that the Company shall not utilize this right more than once in any
twelve-month period; or (3) in any jurisdiction in which the Company would be
required to qualify to do business or to execute a general consent to service of
process in effecting such registration, qualification or compliance; and,
                    
          (b)  subject to the foregoing, file a registration statement covering
the Registrable Securities and other securities so requested to be registered
promptly after receipt of the request or requests of Holder, and in any event
within 30 days of receipt of such request.
                    
     4.   OBLIGATION OF THE COMPANY.  Subject to the terms of the Warrant, in
the event that the Company is to effect the registration of any Registrable
Securities pursuant to Section 2 or 3 hereof, the Company shall promptly:

          (a)  Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of the holders
of a majority of the securities registered thereunder, keep such registration
statement effective for up to one hundred twenty (120) days, or such shorter
period as is required to dispose of all securities covered by such registration
statement.

          (b)  Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

          (c)  Furnish to Holder such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Act, and such other documents as Holder may reasonably request in order to
facilitate the disposition of Registrable Securities owned by Holder.
                    
          (d)  Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by Holder, provided
that the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such states or jurisdictions or to agree to any restrictions as
to the conduct of its business in the ordinary course thereof.
                    
          (e)  In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering.  Holder shall also enter
into and perform its obligations under such underwriting agreement.

                                       2
<PAGE>

          (f)  Notify Holder at any time when a prospectus relating to
Registrable Securities of Holder covered by such registration statement is
required to be delivered under the Act, of the happening of any event as a
result of which the prospectus included in such registration statement, as then
in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances under which they were
made.
                    
          (g)  Furnish, at the request of Holder, on the date that such
Registrable Securities are delivered to the underwriters for sale in connection
with a registration pursuant to the Warrant, if such securities are being sold
through underwriters, or, if such securities are not being sold through
underwriters, on the date that the registration statement with respect to such
securities becomes effective, (i) an opinion, dated such date, of counsel
representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and to Holder and (ii) a letter
dated such date, from the independent certified public accountants of the
Company, in form and substance as is customarily given by independent certified
public accountants to underwriters in an underwritten public offering, addressed
to the underwriters, if any, and to Holder.

     5.   AVAILABILITY OF RULE 144.  Notwithstanding anything in the Warrant or
this Statement of Registration Rights to the contrary, the Company shall not be
obligated to effect any such registration, qualification or compliance, pursuant
to Section 2 or 3, if application of Rule 144 would allow Holder requesting a
registration under Section 2 or 3 to dispose of the Registrable Securities for
which a registration is demanded within a single 90-day period.

     6.   FURNISH INFORMATION.  It shall be a condition precedent to the
obligations of the Company to take any action pursuant to the Warrant that the
selling Holder shall furnish to the Company such information regarding itself,
the Registrable Securities held by Holder, and the intended method of
disposition of such securities as shall be required to effect the registration
of their Registrable Securities.

     7.   EXPENSES.  The Company shall bear and pay all expenses (other than
underwriting discounts and commissions) incurred in connection with any
registration, filing or qualification of Registrable Securities, including
(without limitation) all registration, filing, and qualification fees, legal,
printers and accounting fees relating thereto, and the cost of any reasonable
fees or disbursements of counsel for Holder.

     8.   UNDERWRITING REQUIREMENTS.  In connection with any registrations in
which Registrable Securities have a right to be included pursuant to Section 2
hereof and which involves an underwriting of securities being issued by the
Company, the Company shall not be required, under Section 2 hereof, to include
any of Holder's securities in such underwriting unless Holder accepts the terms
of the underwriting as agreed upon between the Company and the underwriters
selected by it, and then only in such quantity as will not, in the opinion of
the underwriters, jeopardize the success of the offering by the Company.  If the
total amount of securities, including Registrable Securities, requested by
stockholders to be included in such offering exceeds the amount of securities
sold other than by the Company that the underwriters reasonably believe
compatible with the success of the offering, then the Company shall be required
to include in the offering only that number of such securities, including
Registrable Securities, which the underwriters believe will not jeopardize the
success of the offering, the securities so included to be apportioned pro rata
among the selling Holder and other shareholders holding contractual registration
rights according to the total amount of securities entitled to be included
herein owned by each selling stockholder or in such other proportions as shall
mutually be agreed to by Holder and each other selling stockholder.

     9.   INDEMNIFICATION.  In the event any Registrable Securities are included
n a registration statement filed by the Company:

          (a)  The Company will indemnify and holder harmless Holder, its
officers, directors, and agents, any underwriter (as defined in the Act) for
Holder and each person, if any, who controls Holder or underwriter within the
meaning of the Act or the Securities Exchange Act of 1934, as amended (the "1934
Act"), against any losses, claims, damages, or liabilities (joint or several)
asserted by a third party to which they may become subject under the Act, the
1934 Act or other federal or state law, insofar as such losses, claims, damages,
or liabilities (or actions in respect thereof) arise out of or are based upon
any of the following statements, omissions or violations (collectively a
"Violation"):  (i) any untrue statement or alleged untrue statement of a
material fact contained in such registration statement, including any
preliminary prospectus or final prospectus contained therein or any amendments
or supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading, or (iii) any violation or alleged violation of the
Company of the Act, the 1934 Act, any state securities law or any rule or
regulation promulgated under the Act, the 1934 Act or any state securities law;
and the Company will reimburse Holder, any of its officers or directors,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them, as incurred, in connection with investigating or defending any
such loss, claim, damage, liability, or action; PROVIDED, HOWEVER, that the
indemnity agreement contained in this Section 9(a) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable in any such case
for any such loss, claim, damage, liability, or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by such Holder, underwriter or controlling person.
                    
          (b)  Holder will indemnify and hold harmless the Company, each of its
directors, each of its officers who have signed the registration statement, each
person, if any, who controls the Company with the meaning of the Act, any
underwriter and any other shareholder selling securities in such registration
statement or any of its directors or officers or any person who controls such
shareholder, against any losses, claims, damages, or liabilities (joint or
several) asserted by a third party to which the Company or any such director,
officer, controlling person, or underwriter or controlling person, or other such
shareholder or director, officer or controlling person may become subject, under
the Act, the 1934 Act or other federal or state law, insofar as such losses,
claims, damages, or liabilities (or actions in respect thereto) arise out of or
are based upon any Violation, in each case to the extent (and only to the
extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by Holder expressly for use in connection with
such registration; and Holder will reimburse any legal or other expenses
reasonably incurred by the Company or any such director, officer, controlling
person, underwriter or controlling person, other shareholder, officer, director,
or controlling person, as incurred, in connection with investigating or
defending any such loss, claim, damage, liability, or action; PROVIDED, HOWEVER,
that the obligations of Holder hereunder shall be limited to an amount equal to
the net proceeds (equal to the offering price less the exercise price, expenses
and underwriting commissions and discounts) to such Holder of Shares sold as
contemplated herein.  Notwithstanding the foregoing, the indemnity agreement
contained in this Section 9(b) shall not apply to amounts paid in settlement of
any such loss, claim, damage, liability or action if such settlement is effected
without the consent of Holder, which consent shall not be unreasonably withheld.
                    
          (c)  Promptly after receipt by an indemnified party under this
Section 9 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying part under this Section 9, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party

                                       4
<PAGE>

similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; PROVIDED, HOWEVER, that an indemnified party shall
have the right to  retain its own counsel, with the fees and expenses to be paid
by the  indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceeding.  The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to  defend such
action, shall relieve such indemnifying party of any liability to  the
indemnified party under this Section 9, but the omission so to deliver  written
notice to the indemnifying party will not relieve it of any liability  that it
may have to any indemnified party otherwise than under this Section 9.

     10.  REPORTS UNDER THE 1934 ACT.  With a view to making available to Holder
the benefits of Rule 144 promulgated under the Act and any other rule or
regulation of the SEC that may at any time permit Holder to sell securities of
the Company to the public without registration the Company will endeavor to:

          (a)  make and keep public information available, as those terms are
understood and defined in SEC Rule 144;
                    
          (b)  take such action as is necessary to enable Holder to utilize an
abbreviated registration statement for the sale of its Registrable Securities;
                    
          (c)  file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and
                    
          (d)  furnish to Holder, so long as Holder owns any Registrable
Securities, forthwith upon request (i) a written statement by the Company that
it has complied with the reporting requirements of SEC Rule 144, the Act and the
1934 Act, or that it qualifies as a registrant whose securities may be resold
pursuant to Form S-3 (at any time after it so qualifies), (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 in availing Holder of any rule or regulation of the SEC
which permits the selling of any such securities without registration or
pursuant to such form.

     11.  ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause the Company to
register Registrable Securities pursuant to the Warrant may be assigned by
Holder to a permitted transferee or assignee of the Warrant of all 150,000
Shares, provided the Company is, within a reasonable time after such transfer,
furnished with written notice of the name and address of such transferee or
assignee and the securities with respect to which such registration rights are
being assigned; and provided, further, that such assignment shall be effective
only if immediately following such transfer the further disposition of such
securities by the transferee or assignee is restricted under the Act.

         (d)  NO FRACTIONAL SHARES.  No fractional shares shall be issued in

the Company shall make a cash payment therefor upon the basis of the fair market
value per Share as of the date of exercise.
                    
         (e)  COMPANY'S REPRESENTATIONS.
                    
              (i)  The Company is soliciting proxies in connection with its
Annual Meeting of Stockholders for, among other things, a proposal to amend its
Certificate of Incorporation to increase the number of shares of Common Stock
authorized for issuance.  If such proposal is approved by the Company's
stockholders, the Company shall file a Certificate of Amendment to its
Certificate of Incorporation with the Secretary of State of the State of
Delaware (the "Amendment") in order to increase such number of authorized shares
of Common Stock.  From and after the date of filing the Amendment, all Shares
which may be issued upon the exercise of the purchase right represented by this

non-assessable, and free of any liens and encumbrances except for restrictions
on transfer under applicable federal and state securities laws.  From and after

              (iii)     The execution and delivery of this Warrant are not, and
from and after the date of the Amendment, the issuance of the Shares upon
exercise of this Warrant in accordance with the terms hereof will not be,
inconsistent with the Company's Certificate of Incorporation or Bylaws, do not
and will not contravene any law, governmental rule or regulation, judgment or
order applicable to the Company, and do not and will not conflict with or
contravene any provision of, or constitute a default under, any material
indenture, mortgage, contract or other instrument of which the Company is a
party or by which it is bound, or require the registration or filing with or the
taking of any action in respect of or by, any federal, state or local government
authority or agency (other than such consents, approvals, notices, actions, or
filings as have already been obtained or made, as the case may be).

<PAGE>

    5.   ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES.  The number of
Shares issuable upon the exercise of this Warrant and the Warrant Price shall be
subject to adjustment from time to time upon the occurrence of certain events,
as follows:

         (a)  ADJUSTMENT FOR DIVIDENDS IN STOCK.  In case at any time or from
time to time on or after the date hereof the holders of the Common Stock of the
Company (or any shares of stock or other securities at the time receivable upon
the exercise of this Warrant) shall have received or, on or after the record
date fixed for the determination of eligible stockholders, shall have become
entitled to receive, without payment therefor, other or additional stock of the
Company by way of dividend then, and in each case, the Holder of this Warrant
shall, upon the exercise hereof, be entitled to receive, in addition to the
number of shares of Common Stock receivable thereupon, and without payment of
any additional  consideration therefor, the amount of such other or additional
stock of the Company which such Holder would hold on the date of such exercise
had it been the holder of record of such Common Stock on the date hereof and had
thereafter, during the period from the date hereof to and including the date of
such exercise, retained such shares and/or all other additional stock receivable
by it as aforesaid during such period, giving effect to all adjustments called
for during such period by paragraphs (b) and (c) of this Section 5.
                    
         (b)  ADJUSTMENT FOR RECLASSIFICATION OR REORGANIZATION.  In case of
any reclassification or change of the outstanding securities of the Company or
of any consolidation, merger or reorganization of the Company on or after the
date hereof, then and in each such case the Holder of this Warrant, upon the
exercise hereof at any time after the consummation of such reclassification,
change, consolidation, merger or reorganization, shall be entitled to receive,
in lieu of or in addition to the stock or other securities and property
receivable upon the exercise hereof prior to such consummation, the stock or
other securities to which such Holder would have been entitled upon such
consummation if such Holder had exercised this Warrant immediately prior
thereto, all subject to further adjustment as provided in subparagraphs (a) and
(c); in each such case, the terms of this Paragraph 5 shall be applicable to the
shares of stock or other securities property receivable upon the exercise of
this Warrant after such consummation.
                    
         (c)  STOCK SPLITS AND REVERSE STOCK SPLITS.  If, at any time on or
after the date hereof, the Company shall subdivide its outstanding shares of
Common Stock into a greater number of shares, the Warrant Price in effect
immediately prior to such subdivision shall thereby be proportionately reduced
and the number of shares receivable upon exercise of this Warrant shall thereby
be proportionately increased; and, conversely, if at any time on or after the
date hereof the outstanding number of shares of Common Stock shall be combined
into a smaller number of shares, the Warrant Price in effect immediately prior
to such combination shall thereby be proportionately increased and the number of
shares receivable upon exercise of the Warrant shall be proportionately
decreased.
                    
         (d)  ADJUSTMENTS TO WARRANT PRICE.  Whenever the number of Shares
purchasable upon exercise of this Warrant is adjusted, as herein provided, the
Warrant Price shall be adjusted by multiplying the Exercise Price in effect
immediately prior to such

                                       4
<PAGE>

adjustment by a fraction, of which the numerator shall be the number of 
Shares purchasable upon the exercise of each Warrant immediately prior to 
such adjustment, and of which the denominator shall be the number of Shares 
so purchasable immediately thereafter.
                    
         (e)  CERTIFICATES AS TO ADJUSTMENTS.  Upon each adjustment of the
Warrant Price, the Company at its expense shall promptly compute such
adjustment, and furnish the Holder with a certificate of its Chief Financial
Officer setting forth such adjustment and the facts upon which such adjustment
is based.  The Company shall, upon written request, furnish the Holder a
certificate setting forth the Warrant Price in effect upon the date thereof and
the series of adjustments leading to such Warrant Price.

    6.   ACQUISITIONS.

         (a)  ASSUMPTION OF WARRANT.  If upon the closing of any Acquisition
the successor entity assumes the obligations of this Warrant, then this Warrant
shall be exercisable for the same securities, cash, and property as would be
payable for the Shares issuable upon exercise of the unexercised portion of this
Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing.
                    
         (b)  NONASSUMPTION.  If upon the closing of any Acquisition the
successor entity does not assume the obligations of this Warrant and the Holder
has not otherwise exercised this Warrant in full, then the unexercised portion
of this Warrant shall be deemed to have been automatically converted pursuant to
Section 4(c) and thereafter the Holder shall participate in the acquisition on
the same terms as other holders of the same class of securities of the Company.

    7.   NOTICES; INFORMATION; REGISTRATION.

         (a)  NOTICE OF CERTAIN EVENTS.  If the Company proposes at any time
(a) to effect any reclassification or recapitalization of Common Stock; (b) to
merge or consolidate with or into any other corporation, or sell, lease,
license, or convey all or substantially all of its assets, or to liquidate,
dissolve or wind up; or (c) offer holders of registration rights the opportunity
to participate in an underwritten public offering of the company's securities
for cash, then, in connection with each such event, the Company shall give the
Holder at least 14 days prior written notice of the date on which a record will
be taken for such action.  
                    
         (b)  INFORMATION RIGHTS.  So long as the Holder holds this Warrant
and/or any of the Shares, the Company shall deliver to the Holder (a) promptly
after mailing, copies of all notices or other written communications to the
stockholders of the Company, (b) within ninety days after the end of each fiscal
year of the Company, the annual audited financial statements of the Company
audited by independent public accountants of recognized standing and (c) within
forty-five days after the end of each of the first three quarters of each fiscal
year, the Company's quarterly, unaudited financial statements.

                                       5
<PAGE>

         (c)  REGISTRATION UNDER SECURITIES ACT OF 1933.  The Company agrees
that the Shares shall be subject to the registration rights set forth on
Exhibit B.

    8.   COMPLIANCE WITH ACT; TRANSFERABILITY AND NEGOTIABILITY OF WARRANT;
         DISPOSITION OF SHARES.

         (a)  COMPLIANCE WITH ACT.  The Holder, by acceptance hereof, agrees
that this Warrant and the Shares to be issued upon the exercise hereof are being
acquired solely for its own account and not as a nominee for any other party and
not with a view toward the resale or distribution thereof and that it will not
offer, sell or otherwise dispose of this Warrant or any Shares to be issued upon
the exercise hereof except under circumstances which will not result in a
violation of the Act.  This Warrant and the Shares to be issued upon the
exercise hereof (unless registered under the Act) shall be imprinted with a
legend in substantially the following form:
                    
     THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
     SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED,
     ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION
     STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN
     ACCORDANCE WITH RULE 144 UNDER THE ACT, OR THE COMPANY RECEIVES AN
     OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY
     SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER,
     ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND
     PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

In addition, this Warrant and the Shares to be issued upon the exercise hereof
shall bear any legends required by the securities laws of any applicable states.

         (b)  TRANSFERABILITY AND NEGOTIABILITY OF WARRANT.  This Warrant may
not be transferred or assigned in whole or in part without compliance with all
applicable federal and state securities laws by the transferor and the
transferee (including the delivery of investment representation letters and
legal opinions satisfactory to the Company, if requested by the Company and the
transfer is to a person other than a general partner or affiliate of the initial
Holder).  Subject to the provisions of this Warrant with respect to compliance
with the Act, title to this Warrant may be transferred by endorsement and
delivery in the same manner as a negotiable instrument transferable by
endorsement and delivery.  The Company shall act promptly to record transfers of
this Warrant on its books, but the Company may treat the registered holder of
this Warrant as the absolute owner of this Warrant for all purposes,
notwithstanding any notice to the contrary.

                                       6
<PAGE>

         (c)  DISPOSITION OF SHARES.  With respect to any offer, sale, transfer
or other disposition of any Shares acquired pursuant to the exercise of this
Warrant prior to registration of such Shares, except for any such offer, sale,
transfer or other disposition of Shares to an affiliate of the initial Holder,
the Holder and each subsequent holder of this Warrant agrees to give written
notice to the Company prior thereto, describing briefly the manner thereof, and
if such transfer is not pursuant to Rule 144, a written opinion of legal counsel
for such holder, if requested by the Company, to the effect that such offer,
sale or other disposition may be effected without registration or qualification
of such Shares.  Notwithstanding the foregoing, such Shares may be offered, sold
or otherwise disposed of in accordance with Rule 144, provided that the Company
shall have been furnished with such information as the Company may reasonably
request to provide a reasonable assurance that the provisions of Rule 144 have
been satisfied.  Each certificate representing the Shares thus transferred
(except a transfer pursuant to Rule 144) shall bear a restrictive legend as to
the applicable restrictions on transferability in order to insure compliance
with the Act, unless in the aforesaid opinion of legal counsel for the holder,
such legend is not required in order to insure compliance with the Act.

    9.   RIGHTS OF STOCKHOLDERS.  No Holder shall be entitled to vote or
receive dividends or be deemed the holder of Shares or any other securities of
the Company which may at any time be issuable on the exercise of this Warrant

                        STATEMENT OF REGISTRATION RIGHTS
                                           
    1.   DEFINITIONS.  For purposes of the Warrant to which this Statement of
Registration Rights is attached as Exhibit B:

         (a)  The terms "register," "registered," and "registration" refer to a
registration effected by preparing and filing a registration statement or
similar document in compliance with the Securities Act of 1933, as amended (the
"Act"), and the declaration or ordering of effectiveness of such registration
statement or document;
                    
         (b)  The term "Registrable Securities" means the shares of Common
Stock issued or issuable upon exercise of the Warrant;
                    
         (c)  The term "Holder" means the original holder of the Warrant and
any transferee of the Warrant; and
                    
         (d)  The term "Warrant" means the original Warrants issued in
connection with the Stock and Warrant Purchase Agreement, dated as of
October 15, 1997, between the Company, as Seller, and Wexford Spectrum Investors
LLC, a Delaware limited liability company, and Imprimis Investors LLC, a
Delaware limited liability company, as Buyers, and all Warrants issued as a
result of the transfer of such original Warrants.

    2.   COMPANY REGISTRATION.  If (but without any obligation to do so) the
Company proposes at any time before October 15, 2002 to register (including for
this purpose a registration effected by the Company for stockholders other than
Holder) any of its stock or other securities under the Act in connection with
the public offering for its own account of such securities solely for cash
(other than a registration relating solely to the sale of securities to
participants in a Company stock plan, or a registration on any form which does
not include substantially the same information as would be required to be
included in a registration statement covering the sale of the Registrable
Securities), the Company shall, at such time, promptly give Holder written
notice of such registration.  Upon the written request of Holder given within
twenty days after mailing of such notice by the Company, the Company shall,
subject to the provisions of Section 8 hereof and Section 5 of the Warrant,
cause to be registered under the Act all of the Registrable Securities that each
such Holder has requested to be registered.

    3.   DEMAND REGISTRATION.  In case the Company shall, at any time before
October 15, 2002, receive from Holders holding 40% or more of the outstanding
Registrable Securities a written request (to be exercised only once) that the
Company effect a registration and any related qualification or compliance with
respect to all or a part of the Registrable Securities (which registration shall
at the election of Holder either be for a registration for a primary issuance of
the Shares upon the exercise of the Warrant or the resale of the Shares
previously issued upon exercise of the Warrant at the election of Holder) owned
by such Holder, the Company will promptly notify each other Holder (if any) of
such request and will:

<PAGE>

         (a)  as soon as practicable, effect such registration and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of a Holder's
Registrable Securities as are specified in such request, together with all or
such portion of the Registrable Securities of any other holder of registration
rights joining in such request as are specified in a written request given
within 20 days after receipt of such written notice from the Company; PROVIDED,
HOWEVER, that the Company shall not be obligated to effect any such
registration, qualification or compliance, pursuant to this Section 3:  (1) if
the Company has effected a registration of Registrable Securities pursuant to
this Section 3 within the preceding 12 months; (2) if the Company shall furnish
to Holder a certificate signed by the President of the Company stating that in
the good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its stockholders for such registration
to be effected at such time, in which event the Company shall have the right to
defer the filing of the registration statement for a period of not more than 60
days after receipt of the request of Holder under this Section 3; PROVIDED,
HOWEVER, that the Company shall not utilize this right more than once in any
twelve-month period; or (3) in any jurisdiction in which the Company would be
required to qualify to do business or to execute a general consent to service of
process in effecting such registration, qualification or compliance; and,
                    
         (b)  subject to the foregoing, file a registration statement covering
the Registrable Securities and other securities so requested to be registered
promptly after receipt of the request or requests of Holder, and in any event
within 30 days of receipt of such request.
                    
    4.   OBLIGATION OF THE COMPANY.  Subject to the terms of the Warrant, in
the event that the Company is to effect the registration of any Registrable
Securities pursuant to Section 2 or 3 hereof, the Company shall promptly:

         (a)  Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of the holders
of a majority of the securities registered thereunder, keep such registration
statement effective for up to one hundred twenty (120) days, or such shorter
period as is required to dispose of all securities covered by such registration
statement.

         (b)  Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

         (c)  Furnish to Holder such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Act, and such other documents as Holder may reasonably request in order to
facilitate the disposition of Registrable Securities owned by Holder.
                    
         (d)  Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by Holder, provided
that the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such states or jurisdictions or to agree to any restrictions as
to the conduct of its business in the ordinary course thereof.
                    
         (e)  In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering.  Holder shall also enter
into and perform its obligations under such underwriting agreement.
                    
                                       2
<PAGE>

         (f)  Notify Holder at any time when a prospectus relating to
Registrable Securities of Holder covered by such registration statement is
required to be delivered under the Act, of the happening of any event as a
result of which the prospectus included in such registration statement, as then
in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances under which they were
made.
                    
         (g)  Furnish, at the request of Holder, on the date that such
Registrable Securities are delivered to the underwriters for sale in connection
with a registration pursuant to the Warrant, if such securities are being sold
through underwriters, or, if such securities are not being sold through
underwriters, on the date that the registration statement with respect to such
securities becomes effective, (i) an opinion, dated such date, of counsel
representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and to Holder and (ii) a letter
dated such date, from the independent certified public accountants of the
Company, in form and substance as is customarily given by independent certified
public accountants to underwriters in an underwritten public offering, addressed
to the underwriters, if any, and to Holder.

    5.   AVAILABILITY OF RULE 144.  Notwithstanding anything in the Warrant or
this Statement of Registration Rights to the contrary, the Company shall not be
obligated to effect any such registration, qualification or compliance, pursuant
to Section 2 or 3, if application of Rule 144 would allow Holder requesting a
registration under Section 2 or 3 to dispose of the Registrable Securities for
which a registration is demanded within a single 90-day period.

    6.   FURNISH INFORMATION.  It shall be a condition precedent to the
obligations of the Company to take any action pursuant to the Warrant that the
selling Holder shall furnish to the Company such information regarding itself,
the Registrable Securities held by Holder, and the intended method of
disposition of such securities as shall be required to effect the registration
of their Registrable Securities.

    7.   EXPENSES.  The Company shall bear and pay all expenses (other than
underwriting discounts and commissions) incurred in connection with any
registration, filing or qualification of Registrable Securities, including
(without limitation) all registration, filing, and qualification fees, legal,
printers and accounting fees relating thereto, and the cost of any reasonable
fees or disbursements of counsel for Holder.

    8.   UNDERWRITING REQUIREMENTS.  In connection with any registrations in
which Registrable Securities have a right to be included pursuant to Section 2
hereof and which involves an underwriting of securities being issued by the
Company, the Company shall not be required, under Section 2 hereof, to include
any of Holder's securities in such underwriting unless Holder accepts the terms
of the underwriting as agreed upon between the Company and the underwriters
selected by it, and then only in such quantity as will not, in the opinion of
the underwriters, jeopardize the success of the offering by the Company.  If the
total amount of securities, including Registrable Securities, requested by
stockholders to be included in such offering exceeds the amount of securities
sold other than by the Company that the underwriters reasonably believe
compatible with the success of the offering, then the Company shall be required
to include in the offering only that number of such securities, including
Registrable Securities, which the underwriters believe will not jeopardize the
success of the offering, the securities so included to be apportioned pro rata
among the selling Holder and other shareholders holding contractual registration
rights according to the total amount of securities entitled to be included
herein owned by each selling stockholder or in such other proportions as shall
mutually be agreed to by Holder and each other selling stockholder.

                                       3
<PAGE>

    9.   INDEMNIFICATION.  In the event any Registrable Securities are included
n a registration statement filed by the Company:

         (a)  The Company will indemnify and holder harmless Holder, its
officers, directors, and agents, any underwriter (as defined in the Act) for
Holder and each person, if any, who controls Holder or underwriter within the
meaning of the Act or the Securities Exchange Act of 1934, as amended (the "1934
Act"), against any losses, claims, damages, or liabilities (joint or several)
asserted by a third party to which they may become subject under the Act, the
1934 Act or other federal or state law, insofar as such losses, claims, damages,
or liabilities (or actions in respect thereof) arise out of or are based upon
any of the following statements, omissions or violations (collectively a
"Violation"):  (i) any untrue statement or alleged untrue statement of a
material fact contained in such registration statement, including any
preliminary prospectus or final prospectus contained therein or any amendments
or supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading, or (iii) any violation or alleged violation of the
Company of the Act, the 1934 Act, any state securities law or any rule or
regulation promulgated under the Act, the 1934 Act or any state securities law;
and the Company will reimburse Holder, any of its officers or directors,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them, as incurred, in connection with investigating or defending any
such loss, claim, damage, liability, or action; PROVIDED, HOWEVER, that the
indemnity agreement contained in this Section 9(a) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable in any such case
for any such loss, claim, damage, liability, or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by such Holder, underwriter or controlling person.
                    
         (b)  Holder will indemnify and hold harmless the Company, each of its
directors, each of its officers who have signed the registration statement, each
person, if any, who controls the Company with the meaning of the Act, any
underwriter and any other shareholder selling securities in such registration
statement or any of its directors or officers or any person who controls such
shareholder, against any losses, claims, damages, or liabilities (joint or
several) asserted by a third party to which the Company or any such director,
officer, controlling person, or underwriter or controlling person, or other such
shareholder or director, officer or controlling person may become subject, under
the Act, the 1934 Act or other federal or state law, insofar as such losses,
claims, damages, or liabilities (or actions in respect thereto) arise out of or
are based upon any Violation, in each case to the extent (and only to the
extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by Holder expressly for use in connection with
such registration; and Holder will reimburse any legal or other expenses
reasonably incurred by the Company or any such director, officer, controlling
person, underwriter or controlling person, other shareholder, officer, director,
or controlling person, as incurred, in connection with investigating or
defending any such loss, claim, damage, liability, or action; PROVIDED, HOWEVER,
that the obligations of Holder hereunder shall be limited to an amount equal to
the net proceeds (equal to the offering price less the exercise price, expenses
and underwriting commissions and discounts) to such Holder of Shares sold as
contemplated herein.  Notwithstanding the foregoing, the indemnity agreement
contained in this Section 9(b) shall not apply to amounts paid in settlement of
any such loss, claim, damage, liability or action if such settlement is effected
without the consent of Holder, which consent shall not be unreasonably withheld.
                    
         (c)  Promptly after receipt by an indemnified party under this
Section 9 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying part under this Section 9, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party

                                       4
<PAGE>

similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; PROVIDED, HOWEVER, that an indemnified party shall
have the right to  retain its own counsel, with the fees and expenses to be paid
by the  indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceeding.  The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to  defend such
action, shall relieve such indemnifying party of any liability to  the
indemnified party under this Section 9, but the omission so to deliver  written
notice to the indemnifying party will not relieve it of any liability  that it
may have to any indemnified party otherwise than under this Section 9.

    10.  REPORTS UNDER THE 1934 ACT.  With a view to making available to Holder
the benefits of Rule 144 promulgated under the Act and any other rule or
regulation of the SEC that may at any time permit Holder to sell securities of
the Company to the public without registration the Company will endeavor to:

         (a)  make and keep public information available, as those terms are
understood and defined in SEC Rule 144;
                    
         (b)  take such action as is necessary to enable Holder to utilize an
abbreviated registration statement for the sale of its Registrable Securities;
                    
         (c)  file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and
                    
         (d)  furnish to Holder, so long as Holder owns any Registrable
Securities, forthwith upon request (i) a written statement by the Company that
it has complied with the reporting requirements of SEC Rule 144, the Act and the
1934 Act, or that it qualifies as a registrant whose securities may be resold
pursuant to Form S-3 (at any time after it so qualifies), (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 in availing Holder of any rule or regulation of the SEC
which permits the selling of any such securities without registration or
pursuant to such form.

    11.  ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause the Company to
register Registrable Securities pursuant to the Warrant may be assigned by
Holder to a permitted transferee or assignee of the Warrant of all 150,000
Shares, provided the Company is, within a reasonable time after such transfer,
furnished with written notice of the name and address of such transferee or
assignee and the securities with respect to which such registration rights are
being assigned; and provided, further, that such assignment shall be effective
only if immediately following such transfer the further disposition of such
securities by the transferee or assignee is restricted under the Act.

and delivery of the Notice of Exercise (the form of which is attached hereto 
as Exhibit A), duly executed, at the principal office of the Company and (ii) 
payment to the Company of an amount equal to the product of the then

           (d)  NO FRACTIONAL SHARES.  No fractional shares shall be issued 
in connection with any exercise hereunder, but in lieu of such fractional

fair market value per Share as of the date of exercise.
                    
           (e)  COMPANY'S REPRESENTATIONS.
                    
                (i)  The Company is soliciting proxies in connection with its 
Annual Meeting of Stockholders for, among other things, a proposal to amend 
its Certificate of Incorporation to increase the number of shares of Common 
Stock authorized for issuance.  If such proposal is approved by the Company's 
stockholders, the Company shall file a Certificate of Amendment to its 
Certificate of Incorporation with the Secretary of State of the State of 
Delaware (the "Amendment") in order to increase such number of authorized 
shares of Common Stock.  From and after the date of filing the Amendment, all 
Shares which may be issued upon the exercise of the purchase right 
represented by this Warrant shall, upon issuance, be duly authorized, validly 
issued, fully paid and non-assessable, and free of any liens and encumbrances 
except for restrictions on transfer under applicable federal and state 
securities laws.  From and after the date of the Amendment, during the period 
within which the purchase right represented by this Warrant may be exercised, 
the Company shall at all times use its best efforts to have authorized, and 
reserved for the purpose of issuance upon exercise of the purchase right 
represented by this Warrant, a sufficient number of Shares to provide for the 
exercise of the purchase right represented by this Warrant;

                (ii) This Warrant has been duly authorized and executed by 
the Company and is a valid and binding obligation of the Company enforceable 
in accordance with its terms, subject to applicable bankruptcy, insolvency, 
reorganization, moratorium or other laws of general application affecting the 
enforcement of creditors' rights;
                         
                (iii)     The execution and delivery of this Warrant are not, 
and from and after the date of the Amendment, the issuance of the Shares upon 
exercise of this Warrant in accordance with the terms hereof will not be, 
inconsistent with the Company's Certificate of Incorporation or Bylaws, do 
not and will not contravene any law, governmental rule or regulation, 
judgment or order applicable to the Company, and do not and will not conflict 
with or contravene any provision of, or constitute a default under, any 
material indenture, mortgage, contract or other instrument of which the 
Company is a party or by which it is bound, or require the registration or 
filing with or the taking of any action in respect of or by, any federal, 
state or local government authority or agency (other than such consents, 
approvals, notices, actions, or filings as have already been obtained or 
made, as the case may be).

   5.   ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES.  The number of 
Shares issuable upon the exercise of this Warrant and the Warrant Price shall 
be subject to adjustment from time to time upon the occurrence of certain 
events, as follows:

           (a)  ADJUSTMENT FOR DIVIDENDS IN STOCK.  In case at any time or 
from time to time on or after the date hereof the holders of the Common Stock 
of the Company (or any shares of stock or other securities at the time 
receivable upon the exercise of this Warrant) shall have received or, on or 
after the record date fixed for the determination of eligible stockholders, 
shall have become entitled to receive, without payment therefor, other or 
additional stock of the Company by way of dividend then, and in each case, 
the Holder of this Warrant shall, upon the exercise hereof, be entitled to 
receive, in addition to the number of shares of Common Stock receivable 
thereupon, and without payment of any additional  consideration therefor, the 
amount of such other or additional stock of the Company which such Holder 
would hold on the date of such exercise had it been the holder of record of 
such Common Stock on the date hereof and had thereafter, during the period 
from the date hereof to and including the date of such exercise, retained 
such shares and/or all other additional stock receivable by it as aforesaid 
during such period, giving effect to all adjustments called for during such 
period by paragraphs (b) and (c) of this Section 5.
                    
           (b)  ADJUSTMENT FOR RECLASSIFICATION OR REORGANIZATION.  In case 
of any reclassification or change of the outstanding securities of the 
Company or of any consolidation, merger or reorganization of the Company on 
or after the date hereof, then and in each such case the Holder of this 
Warrant, upon the exercise hereof at any time after the consummation of such 
reclassification, change, consolidation, merger or reorganization, shall be 
entitled to receive, in lieu of or in addition to the stock or other 
securities and property receivable upon the exercise hereof prior to such 
consummation, the stock or other securities to which such Holder would have 
been entitled upon such consummation if such Holder had exercised this 
Warrant immediately prior thereto, all subject to further adjustment as 
provided in subparagraphs (a) and (c); in each such case, the terms of this 
Paragraph 5 shall be applicable to the shares of stock or other securities 
property receivable upon the exercise of this Warrant after such consummation.
                    
           (c)  STOCK SPLITS AND REVERSE STOCK SPLITS.  If, at any time on or 
after the date hereof, the Company shall subdivide its outstanding shares of 
Common Stock into a greater number of shares, the Warrant Price in effect 
immediately prior to such subdivision shall thereby be proportionately 
reduced and the number of shares receivable upon exercise of this Warrant 
shall thereby be proportionately increased; and, conversely, if at any time 
on or after the date hereof the outstanding number of shares of Common Stock 
shall be combined into a smaller number of shares, the Warrant Price in 
effect immediately prior to such combination shall thereby be proportionately 
increased and the number of shares receivable upon exercise of the Warrant 
shall be proportionately decreased.
                    
           (d)  ADJUSTMENTS TO WARRANT PRICE.  Whenever the number of Shares 
purchasable upon exercise of this Warrant is adjusted, as herein provided, 
the Warrant Price shall be adjusted by multiplying the Exercise Price in 
effect immediately prior to such

                                       4
<PAGE>

adjustment by a fraction, of which the numerator shall be the number of 
Shares purchasable upon the exercise of each Warrant immediately prior to 
such adjustment, and of which the denominator shall be the number of Shares 
so purchasable immediately thereafter.
                    
           (e)  CERTIFICATES AS TO ADJUSTMENTS.  Upon each adjustment of the 
Warrant Price, the Company at its expense shall promptly compute such 
adjustment, and furnish the Holder with a certificate of its Chief Financial 
Officer setting forth such adjustment and the facts upon which such 
adjustment is based.  The Company shall, upon written request, furnish the 
Holder a certificate setting forth the Warrant Price in effect upon the date 
thereof and the series of adjustments leading to such Warrant Price.

   6.   ACQUISITIONS.

           (a)  ASSUMPTION OF WARRANT.  If upon the closing of any 
Acquisition the successor entity assumes the obligations of this Warrant, 
then this Warrant shall be exercisable for the same securities, cash, and 
property as would be payable for the Shares issuable upon exercise of the 
unexercised portion of this Warrant as if such Shares were outstanding on the 
record date for the Acquisition and subsequent closing.
                    
           (b)  NONASSUMPTION.  If upon the closing of any Acquisition the 
successor entity does not assume the obligations of this Warrant and the 
Holder has not otherwise exercised this Warrant in full, then the unexercised 
portion of this Warrant shall be deemed to have been automatically converted 
pursuant to Section 4(c) and thereafter the Holder shall participate in the 
acquisition on the same terms as other holders of the same class of 
securities of the Company.

   7.   NOTICES; INFORMATION; REGISTRATION.

           (a)  NOTICE OF CERTAIN EVENTS.  If the Company proposes at any 
time (a) to effect any reclassification or recapitalization of Common Stock; 
(b) to merge or consolidate with or into any other corporation, or sell, 
lease, license, or convey all or substantially all of its assets, or to 
liquidate, dissolve or wind up; or (c) offer holders of registration rights 
the opportunity to participate in an underwritten public offering of the 
company's securities for cash, then, in connection with each such event, the 
Company shall give the Holder at least 14 days prior written notice of the 
date on which a record will be taken for such action.  
                    
           (b)  INFORMATION RIGHTS.  So long as the Holder holds this Warrant 
and/or any of the Shares, the Company shall deliver to the Holder (a) 
promptly after mailing, copies of all notices or other written communications 
to the stockholders of the Company, (b) within ninety days after the end of 
each fiscal year of the Company, the annual audited financial statements of 
the Company audited by independent public accountants of recognized standing 
and (c) within forty-five days after the end of each of the first three 
quarters of each fiscal year, the Company's quarterly, unaudited financial 
statements.
                    
                                       5
<PAGE>

           (c)  REGISTRATION UNDER SECURITIES ACT OF 1933.  The Company 
agrees that the Shares shall be subject to the registration rights set forth 
on Exhibit B.

   8.   COMPLIANCE WITH ACT; TRANSFERABILITY AND NEGOTIABILITY OF WARRANT;    
        DISPOSITION OF SHARES.

           (a)  COMPLIANCE WITH ACT.  The Holder, by acceptance hereof, 
agrees that this Warrant and the Shares to be issued upon the exercise hereof 
are being acquired solely for its own account and not as a nominee for any 
other party and not with a view toward the resale or distribution thereof and 
that it will not offer, sell or otherwise dispose of this Warrant or any 
Shares to be issued upon the exercise hereof except under circumstances which 
will not result in a violation of the Act.  This Warrant and the Shares to be 
issued upon the exercise hereof (unless registered under the Act) shall be 
imprinted with a legend in substantially the following form:

          THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED 
          UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE 
          SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS 
          AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT COVERING 
          SUCH SECURITIES, THE SALE IS MADE IN ACCORDANCE WITH RULE 144 
          UNDER THE ACT, OR THE COMPANY RECEIVES AN OPINION OF COUNSEL 
          FOR THE HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO 
          THE COMPANY, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR 
          HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS 
          DELIVERY REQUIREMENTS OF SUCH ACT.

In addition, this Warrant and the Shares to be issued upon the exercise hereof
shall bear any legends required by the securities laws of any applicable states.

         (b)  TRANSFERABILITY AND NEGOTIABILITY OF WARRANT.  This Warrant may
not be transferred or assigned in whole or in part without compliance with all
applicable federal and state securities laws by the transferor and the
transferee (including the delivery of investment representation letters and
legal opinions satisfactory to the Company, if requested by the Company and the
transfer is to a person other than a general partner or affiliate of the initial
Holder).  Subject to the provisions of this Warrant with respect to compliance
with the Act, title to this Warrant may be transferred by endorsement and
delivery in the same manner as a negotiable instrument transferable by
endorsement and delivery.  The Company shall act promptly to record transfers of
this Warrant on its books, but the Company may treat the registered holder of
this Warrant as the absolute owner of this Warrant for all purposes,
notwithstanding any notice to the contrary.

                                       6
<PAGE>

         (c)  DISPOSITION OF SHARES.  With respect to any offer, sale, transfer
or other disposition of any Shares acquired pursuant to the exercise of this
Warrant prior to registration of such Shares, except for any such offer, sale,
transfer or other disposition of Shares to an affiliate of the initial Holder,
the Holder and each subsequent holder of this Warrant agrees to give written
notice to the Company prior thereto, describing briefly the manner thereof, and
if such transfer is not pursuant to Rule 144, a written opinion of legal counsel
for such holder, if requested by the Company, to the effect that such offer,
sale or other disposition may be effected without registration or qualification
of such Shares.  Notwithstanding the foregoing, such Shares may be offered, sold
or otherwise disposed of in accordance with Rule 144, provided that the Company
shall have been furnished with such information as the Company may reasonably
request to provide a reasonable assurance that the provisions of Rule 144 have
been satisfied.  Each certificate representing the Shares thus transferred
(except a transfer pursuant to Rule 144) shall bear a restrictive legend as to
the applicable restrictions on transferability in order to insure compliance
with the Act, unless in the aforesaid opinion of legal counsel for the holder,
such legend is not required in order to insure compliance with the Act.

   9.   RIGHTS OF STOCKHOLDERS.  No Holder shall be entitled to vote or
receive dividends or be deemed the holder of Shares or any other securities of
the Company which may at any time be issuable on the exercise of this Warrant
for any purpose, nor shall anything contained herein be construed to confer upon
the Holder, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action (whether upon any recapitalization, issuance of stock,
reclassification of stock, consolidation, merger, transfer of assets or
otherwise) or, except as expressly required herein, to receive notice of
meetings, or to receive dividends or subscription rights or otherwise until this
Warrant shall have been exercised and the Shares issuable upon exercise hereof
shall have become deliverable, as provided herein.

   10.  REPLACEMENT OF WARRANTS.  On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, on surrender and  cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

   11.  EXCHANGE OF WARRANT.  Subject to the other provisions of this Warrant,
on surrender of this Warrant for exchange, and subject to the provisions of this
Warrant with respect to compliance with the Act, the Company at its expense
shall issue to or on the order of the Holder a new warrant or warrants of like
tenor, in the name of the Holder or as the Holder (on payment by the Holder of
any applicable transfer taxes) may direct, for the number of Shares issuable
upon exercise thereof.

   12.  NOTICES.  All notices and other communications from the Company to the
Holder, or vice versa, shall be deemed delivered and effective when given
personally or

                                       7
<PAGE>

mailed by first-class registered or certified mail, postage prepaid, at such 
address as may have been furnished to the Company or the Holder, as the case 
may be, in writing by the Company or such Holder from time to time.

   13.  WAIVER.  This Warrant and any term hereof may be changed, waived,
discharged or terminated only by an instrument in writing signed by the party
against which enforcement of such change, waiver, discharge or termination is
sought.

   14.  GOVERNING LAW.  This Warrant shall be governed by and construed in
accordance with the laws of the State of Delaware.

   15.  TITLES AND SUBTITLES; FORMS OF PRONOUNS.  The titles of the Sections

                         STATEMENT OF REGISTRATION RIGHTS

   1.   DEFINITIONS.  For purposes of the Warrant to which this Statement of
Registration Rights is attached as Exhibit B:

        (a)  The terms "register," "registered," and "registration" refer to a
registration effected by preparing and filing a registration statement or
similar document in compliance with the Securities Act of 1933, as amended (the
"Act"), and the declaration or ordering of effectiveness of such registration
statement or document;
                    
        (b)  The term "Registrable Securities" means the shares of Common
Stock issued or issuable upon exercise of the Warrant;
                    
        (c)  The term "Holder" means the original holder of the Warrant and
any transferee of the Warrant; and
                    
        (d)  The term "Warrant" means the original Warrants issued in
connection with the Stock and Warrant Purchase Agreement, dated as of
October 15, 1997, between the Company, as Seller, and Wexford Spectrum Investors
LLC, a Delaware limited liability company, and Imprimis Investors LLC, a
Delaware limited liability company, as Buyers, and all Warrants issued as a
result of the transfer of such original Warrants.

   2.   COMPANY REGISTRATION.  If (but without any obligation to do so) the
Company proposes at any time before October 15, 2002 to register (including for
this purpose a registration effected by the Company for stockholders other than
Holder) any of its stock or other securities under the Act in connection with
the public offering for its own account of such securities solely for cash
(other than a registration relating solely to the sale of securities to
participants in a Company stock plan, or a registration on any form which does
not include substantially the same information as would be required to be
included in a registration statement covering the sale of the Registrable
Securities), the Company shall, at such time, promptly give Holder written
notice of such registration.  Upon the written request of Holder given within
twenty days after mailing of such notice by the Company, the Company shall,
subject to the provisions of Section 8 hereof and Section 5 of the Warrant,
cause to be registered under the Act all of the Registrable Securities that each
such Holder has requested to be registered.

   3.   DEMAND REGISTRATION.  In case the Company shall, at any time before
October 15, 2002, receive from Holders holding 40% or more of the outstanding
Registrable Securities a written request (to be exercised only once) that the
Company effect a registration and any related qualification or compliance with
respect to all or a part of the Registrable Securities (which registration shall
at the election of Holder either be for a registration for a primary issuance of
the Shares upon the exercise of the Warrant or the resale of the Shares
previously issued upon exercise of the Warrant at the election of Holder) owned
by such Holder, the Company will promptly notify each other Holder (if any) of
such request and will:

<PAGE>

        (a)  as soon as practicable, effect such registration and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of a Holder's
Registrable Securities as are specified in such request, together with all or
such portion of the Registrable Securities of any other holder of registration
rights joining in such request as are specified in a written request given
within 20 days after receipt of such written notice from the Company; PROVIDED,
HOWEVER, that the Company shall not be obligated to effect any such
registration, qualification or compliance, pursuant to this Section 3:  (1) if
the Company has effected a registration of Registrable Securities pursuant to
this Section 3 within the preceding 12 months; (2) if the Company shall furnish
to Holder a certificate signed by the President of the Company stating that in
the good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its stockholders for such registration
to be effected at such time, in which event the Company shall have the right to
defer the filing of the registration statement for a period of not more than 60
days after receipt of the request of Holder under this Section 3; PROVIDED,
HOWEVER, that the Company shall not utilize this right more than once in any
twelve-month period; or (3) in any jurisdiction in which the Company would be
required to qualify to do business or to execute a general consent to service of
process in effecting such registration, qualification or compliance; and,
                    
        (b)  subject to the foregoing, file a registration statement covering
the Registrable Securities and other securities so requested to be registered
promptly after receipt of the request or requests of Holder, and in any event
within 30 days of receipt of such request.
                    
   4.   OBLIGATION OF THE COMPANY.  Subject to the terms of the Warrant, in
the event that the Company is to effect the registration of any Registrable
Securities pursuant to Section 2 or 3 hereof, the Company shall promptly:

        (a)  Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of the holders
of a majority of the securities registered thereunder, keep such registration
statement effective for up to one hundred twenty (120) days, or such shorter
period as is required to dispose of all securities covered by such registration
statement.

        (b)  Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

        (c)  Furnish to Holder such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Act, and such other documents as Holder may reasonably request in order to
facilitate the disposition of Registrable Securities owned by Holder.
                    
        (d)  Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by Holder, provided
that the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such states or jurisdictions or to agree to any restrictions as
to the conduct of its business in the ordinary course thereof.
                    
        (e)  In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering.  Holder shall also enter
into and perform its obligations under such underwriting agreement.

                                       2

        (f)  Notify Holder at any time when a prospectus relating to
Registrable Securities of Holder covered by such registration statement is
required to be delivered under the Act, of the happening of any event as a
result of which the prospectus included in such registration statement, as then
in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances under which they were
made.
                    
        (g)  Furnish, at the request of Holder, on the date that such
Registrable Securities are delivered to the underwriters for sale in connection
with a registration pursuant to the Warrant, if such securities are being sold
through underwriters, or, if such securities are not being sold through
underwriters, on the date that the registration statement with respect to such
securities becomes effective, (i) an opinion, dated such date, of counsel
representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and to Holder and (ii) a letter
dated such date, from the independent certified public accountants of the
Company, in form and substance as is customarily given by independent certified
public accountants to underwriters in an underwritten public offering, addressed
to the underwriters, if any, and to Holder.

   5.   AVAILABILITY OF RULE 144.  Notwithstanding anything in the Warrant or
this Statement of Registration Rights to the contrary, the Company shall not be
obligated to effect any such registration, qualification or compliance, pursuant
to Section 2 or 3, if application of Rule 144 would allow Holder requesting a
registration under Section 2 or 3 to dispose of the Registrable Securities for
which a registration is demanded within a single 90-day period.

   6.   FURNISH INFORMATION.  It shall be a condition precedent to the
obligations of the Company to take any action pursuant to the Warrant that the
selling Holder shall furnish to the Company such information regarding itself,
the Registrable Securities held by Holder, and the intended method of
disposition of such securities as shall be required to effect the registration
of their Registrable Securities.

   7.   EXPENSES.  The Company shall bear and pay all expenses (other than
underwriting discounts and commissions) incurred in connection with any
registration, filing or qualification of Registrable Securities, including
(without limitation) all registration, filing, and qualification fees, legal,
printers and accounting fees relating thereto, and the cost of any reasonable
fees or disbursements of counsel for Holder.

   8.   UNDERWRITING REQUIREMENTS.  In connection with any registrations in
which Registrable Securities have a right to be included pursuant to Section 2
hereof and which involves an underwriting of securities being issued by the
Company, the Company shall not be required, under Section 2 hereof, to include
any of Holder's securities in such underwriting unless Holder accepts the terms
of the underwriting as agreed upon between the Company and the underwriters
selected by it, and then only in such quantity as will not, in the opinion of
the underwriters, jeopardize the success of the offering by the Company.  If the
total amount of securities, including Registrable Securities, requested by
stockholders to be included in such offering exceeds the amount of securities
sold other than by the Company that the underwriters reasonably believe
compatible with the success of the offering, then the Company shall be required
to include in the offering only that number of such securities, including
Registrable Securities, which the underwriters believe will not jeopardize the
success of the offering, the securities so included to be apportioned pro rata
among the selling Holder and other shareholders holding contractual registration
rights according to the total amount of securities entitled to be included
herein owned by each selling stockholder or in such other proportions as shall
mutually be agreed to by Holder and each other selling stockholder.

                                       3
<PAGE>

   9.   INDEMNIFICATION.  In the event any Registrable Securities are included
n a registration statement filed by the Company:

        (a)  The Company will indemnify and holder harmless Holder, its
officers, directors, and agents, any underwriter (as defined in the Act) for
Holder and each person, if any, who controls Holder or underwriter within the
meaning of the Act or the Securities Exchange Act of 1934, as amended (the "1934
Act"), against any losses, claims, damages, or liabilities (joint or several)
asserted by a third party to which they may become subject under the Act, the
1934 Act or other federal or state law, insofar as such losses, claims, damages,
or liabilities (or actions in respect thereof) arise out of or are based upon
any of the following statements, omissions or violations (collectively a
"Violation"):  (i) any untrue statement or alleged untrue statement of a
material fact contained in such registration statement, including any
preliminary prospectus or final prospectus contained therein or any amendments
or supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading, or (iii) any violation or alleged violation of the
Company of the Act, the 1934 Act, any state securities law or any rule or
regulation promulgated under the Act, the 1934 Act or any state securities law;
and the Company will reimburse Holder, any of its officers or directors,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them, as incurred, in connection with investigating or defending any
such loss, claim, damage, liability, or action; PROVIDED, HOWEVER, that the
indemnity agreement contained in this Section 9(a) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable in any such case
for any such loss, claim, damage, liability, or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by such Holder, underwriter or controlling person.
                    
        (b)  Holder will indemnify and hold harmless the Company, each of its
directors, each of its officers who have signed the registration statement, each
person, if any, who controls the Company with the meaning of the Act, any
underwriter and any other shareholder selling securities in such registration
statement or any of its directors or officers or any person who controls such
shareholder, against any losses, claims, damages, or liabilities (joint or
several) asserted by a third party to which the Company or any such director,
officer, controlling person, or underwriter or controlling person, or other such
shareholder or director, officer or controlling person may become subject, under
the Act, the 1934 Act or other federal or state law, insofar as such losses,
claims, damages, or liabilities (or actions in respect thereto) arise out of or
are based upon any Violation, in each case to the extent (and only to the
extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by Holder expressly for use in connection with
such registration; and Holder will reimburse any legal or other expenses
reasonably incurred by the Company or any such director, officer, controlling
person, underwriter or controlling person, other shareholder, officer, director,
or controlling person, as incurred, in connection with investigating or
defending any such loss, claim, damage, liability, or action; PROVIDED, HOWEVER,
that the obligations of Holder hereunder shall be limited to an amount equal to
the net proceeds (equal to the offering price less the exercise price, expenses
and underwriting commissions and discounts) to such Holder of Shares sold as
contemplated herein.  Notwithstanding the foregoing, the indemnity agreement
contained in this Section 9(b) shall not apply to amounts paid in settlement of
any such loss, claim, damage, liability or action if such settlement is effected
without the consent of Holder, which consent shall not be unreasonably withheld.
                    
        (c)  Promptly after receipt by an indemnified party under this
Section 9 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying part under this Section 9, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party

                                       4
<PAGE>

similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; PROVIDED, HOWEVER, that an indemnified party shall
have the right to  retain its own counsel, with the fees and expenses to be paid
by the  indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceeding.  The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to  defend such
action, shall relieve such indemnifying party of any liability to  the
indemnified party under this Section 9, but the omission so to deliver  written
notice to the indemnifying party will not relieve it of any liability  that it
may have to any indemnified party otherwise than under this Section 9.

   10.  REPORTS UNDER THE 1934 ACT.  With a view to making available to Holder
the benefits of Rule 144 promulgated under the Act and any other rule or
regulation of the SEC that may at any time permit Holder to sell securities of
the Company to the public without registration the Company will endeavor to:

        (a)  make and keep public information available, as those terms are
understood and defined in SEC Rule 144;
                    
        (b)  take such action as is necessary to enable Holder to utilize an
abbreviated registration statement for the sale of its Registrable Securities;
                    
        (c)  file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and
                    
        (d)  furnish to Holder, so long as Holder owns any Registrable
Securities, forthwith upon request (i) a written statement by the Company that
it has complied with the reporting requirements of SEC Rule 144, the Act and the
1934 Act, or that it qualifies as a registrant whose securities may be resold
pursuant to Form S-3 (at any time after it so qualifies), (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 in availing Holder of any rule or regulation of the SEC
which permits the selling of any such securities without registration or
pursuant to such form.

   11.  ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause the Company to
register Registrable Securities pursuant to the Warrant may be assigned by
Holder to a permitted transferee or assignee of the Warrant of all 150,000
Shares, provided the Company is, within a reasonable time after such transfer,
furnished with written notice of the name and address of such transferee or
assignee and the securities with respect to which such registration rights are
being assigned; and provided, further, that such assignment shall be effective
only if immediately following such transfer the further disposition of such
securities by the transferee or assignee is restricted under the Act.

    5.   ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES.  The number of
Shares issuable upon the exercise of this Warrant and the Warrant Price shall be
subject to adjustment from time to time upon the occurrence of certain events,
as follows:

         (a)  ADJUSTMENT FOR DIVIDENDS IN STOCK.  In case at any time or from
time to time on or after the date hereof the holders of the Common Stock of the
Company (or any shares of stock or other securities at the time receivable upon
the exercise of this Warrant) shall have received or, on or after the record
date fixed for the determination of eligible stockholders, shall have become
entitled to receive, without payment therefor, other or additional stock of the
Company by way of dividend then, and in each case, the Holder of this Warrant
shall, upon the exercise hereof, be entitled to receive, in addition to the
number of shares of Common Stock receivable thereupon, and without payment of
any additional  consideration therefor, the amount of such other or additional
stock of the Company which such Holder would hold on the date of such exercise
had it been the holder of record of such Common Stock on the date hereof and had
thereafter, during the period from the date hereof to and including the date of
such exercise, retained such shares and/or all other additional stock receivable
by it as aforesaid during such period, giving effect to all adjustments called
for during such period by paragraphs (b) and (c) of this Section 5.

         (b)  ADJUSTMENT FOR RECLASSIFICATION OR REORGANIZATION.  In case of
any reclassification or change of the outstanding securities of the Company or
of any consolidation, merger or reorganization of the Company on or after the
date hereof, then and in each such case the Holder of this Warrant, upon the
exercise hereof at any time after the consummation of such reclassification,
change, consolidation, merger or reorganization, shall be entitled to receive,
in lieu of or in addition to the stock or other securities and property
receivable upon the exercise hereof prior to such consummation, the stock or
other securities to which such Holder would have been entitled upon such
consummation if such Holder had exercised this Warrant immediately prior
thereto, all subject to further adjustment as provided in subparagraphs (a) and
(c); in each such case, the terms of this Paragraph 5 shall be applicable to the
shares of stock or other securities property receivable upon the exercise of
this Warrant after such consummation.

         (c)  STOCK SPLITS AND REVERSE STOCK SPLITS.  If, at any time on or
after the date hereof, the Company shall subdivide its outstanding shares of
Common Stock into a greater number of shares, the Warrant Price in effect
immediately prior to such subdivision shall thereby be proportionately reduced
and the number of shares receivable upon exercise of this Warrant shall thereby
be proportionately increased; and, conversely, if at any time on or after the
date hereof the outstanding number of shares of Common Stock shall be combined
into a smaller number of shares, the Warrant Price in effect immediately prior
to such combination shall thereby be proportionately increased and the number of
shares receivable upon exercise of the Warrant shall be proportionately
decreased.

         (d)  ADJUSTMENTS TO WARRANT PRICE.  Whenever the number of Shares
purchasable upon exercise of this Warrant is adjusted, as herein provided, the
Warrant Price shall be adjusted by multiplying the Exercise Price in effect
immediately prior to such


                                          4
<PAGE>

adjustment by a fraction, of which the numerator shall be the number of Shares
purchasable upon the exercise of each Warrant immediately prior to such
adjustment, and of which the denominator shall be the number of Shares so
purchasable immediately thereafter.

         (e)  CERTIFICATES AS TO ADJUSTMENTS.  Upon each adjustment of the
Warrant Price, the Company at its expense shall promptly compute such
adjustment, and furnish the Holder with a certificate of its Chief Financial
Officer setting forth such adjustment and the facts upon which such adjustment
is based.  The Company shall, upon written request, furnish the Holder a
certificate setting forth the Warrant Price in effect upon the date thereof and
the series of adjustments leading to such Warrant Price.

    6.   ACQUISITIONS.

         (a)  ASSUMPTION OF WARRANT.  If upon the closing of any Acquisition
the successor entity assumes the obligations of this Warrant, then this Warrant
shall be exercisable for the same securities, cash, and property as would be
payable for the Shares issuable upon exercise of the unexercised portion of this
Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing.

         (b)  NONASSUMPTION.  If upon the closing of any Acquisition the
successor entity does not assume the obligations of this Warrant and the Holder
has not otherwise exercised this Warrant in full, then the unexercised portion
of this Warrant shall be deemed to have been automatically converted pursuant to
Section 4(c) and thereafter the Holder shall participate in the acquisition on
the same terms as other holders of the same class of securities of the Company.

    7.   NOTICES; INFORMATION; REGISTRATION.

         (a)  NOTICE OF CERTAIN EVENTS.  If the Company proposes at any time
(a) to effect any reclassification or recapitalization of Common Stock; (b) to
merge or consolidate with or into any other corporation, or sell, lease,
license, or convey all or substantially all of its assets, or to liquidate,
dissolve or wind up; or (c) offer holders of registration rights the opportunity
to participate in an underwritten public offering of the company's securities
for cash, then, in connection with each such event, the Company shall give the
Holder at least 14 days prior written notice of the date on which a record will
be taken for such action.

         (b)  INFORMATION RIGHTS.  So long as the Holder holds this Warrant
and/or any of the Shares, the Company shall deliver to the Holder (a) promptly
after mailing, copies of all notices or other written communications to the
stockholders of the Company, (b) within ninety days after the end of each fiscal
year of the Company, the annual audited financial statements of the Company
audited by independent public accountants of recognized standing and (c) within
forty-five days after the end of each of the first three quarters of each fiscal
year, the Company's quarterly, unaudited financial statements.


                                          5

         (c)  REGISTRATION UNDER SECURITIES ACT OF 1933.  The Company agrees
that the Shares shall be subject to the registration rights set forth on
Exhibit B.

    8.   COMPLIANCE WITH ACT; TRANSFERABILITY AND NEGOTIABILITY OF WARRANT;
    DISPOSITION OF SHARES.

         (a)  COMPLIANCE WITH ACT.  The Holder, by acceptance hereof, agrees
that this Warrant and the Shares to be issued upon the exercise hereof are being
acquired solely for its own account and not as a nominee for any other party and
not with a view toward the resale or distribution thereof and that it will not
offer, sell or otherwise dispose of this Warrant or any Shares to be issued upon
the exercise hereof except under circumstances which will not result in a
violation of the Act.  This Warrant and the Shares to be issued upon the
exercise hereof (unless registered under the Act) shall be imprinted with a
legend in substantially the following form:

    THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
    SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED,
    ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION
    STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN
    ACCORDANCE WITH RULE 144 UNDER THE ACT, OR THE COMPANY RECEIVES AN OPINION
    OF COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO
    THE COMPANY, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION
    IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF
    SUCH ACT.

In addition, this Warrant and the Shares to be issued upon the exercise hereof
shall bear any legends required by the securities laws of any applicable states.

         (b)  TRANSFERABILITY AND NEGOTIABILITY OF WARRANT.  This Warrant may
not be transferred or assigned in whole or in part without compliance with all
applicable federal and state securities laws by the transferor and the
transferee (including the delivery of investment representation letters and
legal opinions satisfactory to the Company, if requested by the Company and the
transfer is to a person other than a general partner or affiliate of the initial
Holder).  Subject to the provisions of this Warrant with respect to compliance
with the Act, title to this Warrant may be transferred by endorsement and
delivery in the same manner as a negotiable instrument transferable by
endorsement and delivery.  The Company shall act promptly to record transfers of
this Warrant on its books, but the Company may treat the registered holder of
this Warrant as the absolute owner of this Warrant for all purposes,
notwithstanding any notice to the contrary.


                                          6
<PAGE>

         (c)  DISPOSITION OF SHARES.  With respect to any offer, sale, transfer
or other disposition of any Shares acquired pursuant to the exercise of this
Warrant prior to registration of such Shares, except for any such offer, sale,
transfer or other disposition of Shares to an affiliate of the initial Holder,
the Holder and each subsequent holder of this Warrant agrees to give written
notice to the Company prior thereto, describing briefly the manner thereof, and
if such transfer is not pursuant to Rule 144, a written opinion of legal counsel
for such holder, if requested by the Company, to the effect that such offer,
sale or other disposition may be effected without registration or qualification
of such Shares.  Notwithstanding the foregoing, such Shares may be offered, sold
or otherwise disposed of in accordance with Rule 144, provided that the Company
shall have been furnished with such information as the Company may reasonably
request to provide a reasonable assurance that the provisions of Rule 144 have
been satisfied.  Each certificate representing the Shares thus transferred
(except a transfer pursuant to Rule 144) shall bear a restrictive legend as to
the applicable restrictions on transferability in order to insure compliance

                           STATEMENT OF REGISTRATION RIGHTS



    1.   DEFINITIONS.  For purposes of the Warrant to which this Statement of
Registration Rights is attached as Exhibit B:

         (a)  The terms "register," "registered," and "registration" refer to a
registration effected by preparing and filing a registration statement or
similar document in compliance with the Securities Act of 1933, as amended (the
"Act"), and the declaration or ordering of effectiveness of such registration
statement or document;

         (b)  The term "Registrable Securities" means the shares of Common
Stock issued or issuable upon exercise of the Warrant;

         (c)  The term "Holder" means the original holder of the Warrant and
any transferee of the Warrant; and

         (d)  The term "Warrant" means the original Warrants issued in
connection with the Stock and Warrant Purchase Agreement, dated as of
October 15, 1997, between the Company, as Seller, and Wexford Spectrum Investors
LLC, a Delaware limited liability company, and Imprimis Investors LLC, a
Delaware limited liability company, as Buyers, and all Warrants issued as a
result of the transfer of such original Warrants.

    2.   COMPANY REGISTRATION.  If (but without any obligation to do so) the
Company proposes at any time before October 15, 2002 to register (including for
this purpose a registration effected by the Company for stockholders other than
Holder) any of its stock or other securities under the Act in connection with
the public offering for its own account of such securities solely for cash
(other than a registration relating solely to the sale of securities to
participants in a Company stock plan, or a registration on any form which does
not include substantially the same information as would be required to be
included in a registration statement covering the sale of the Registrable
Securities), the Company shall, at such time, promptly give Holder written
notice of such registration.  Upon the written request of Holder given within
twenty days after mailing of such notice by the Company, the Company shall,
subject to the provisions of Section 8 hereof and Section 5 of the Warrant,
cause to be registered under the Act all of the Registrable Securities that each
such Holder has requested to be registered.

    3.   DEMAND REGISTRATION.  In case the Company shall, at any time before
October 15, 2002, receive from Holders holding 40% or more of the outstanding
Registrable Securities a written request (to be exercised only once) that the
Company effect a registration and any related qualification or compliance with
respect to all or a part of the Registrable Securities (which registration shall
at the election of Holder either be for a registration for a primary issuance of
the Shares upon the exercise of the Warrant or the resale of the Shares
previously issued upon exercise of the Warrant at the election of Holder) owned
by such Holder, the Company will promptly notify each other Holder (if any) of
such request and will:

<PAGE>

         (a)  as soon as practicable, effect such registration and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of a Holder's
Registrable Securities as are specified in such request, together with all or
such portion of the Registrable Securities of any other holder of registration
rights joining in such request as are specified in a written request given
within 20 days after receipt of such written notice from the Company; PROVIDED,
HOWEVER, that the Company shall not be obligated to effect any such
registration, qualification or compliance, pursuant to this Section 3:  (1) if
the Company has effected a registration of Registrable Securities pursuant to
this Section 3 within the preceding 12 months; (2) if the Company shall furnish
to Holder a certificate signed by the President of the Company stating that in
the good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its stockholders for such registration
to be effected at such time, in which event the Company shall have the right to
defer the filing of the registration statement for a period of not more than 60
days after receipt of the request of Holder under this Section 3; PROVIDED,
HOWEVER, that the Company shall not utilize this right more than once in any
twelve-month period; or (3) in any jurisdiction in which the Company would be
required to qualify to do business or to execute a general consent to service of
process in effecting such registration, qualification or compliance; and,

         (b)  subject to the foregoing, file a registration statement covering
the Registrable Securities and other securities so requested to be registered
promptly after receipt of the request or requests of Holder, and in any event
within 30 days of receipt of such request.

    4.   OBLIGATION OF THE COMPANY.  Subject to the terms of the Warrant, in
the event that the Company is to effect the registration of any Registrable
Securities pursuant to Section 2 or 3 hereof, the Company shall promptly:

         (a)  Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of the holders
of a majority of the securities registered thereunder, keep such registration
statement effective for up to one hundred twenty (120) days, or such shorter
period as is required to dispose of all securities covered by such registration
statement.

         (b)  Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

         (c)  Furnish to Holder such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Act, and such other documents as Holder may reasonably request in order to
facilitate the disposition of Registrable Securities owned by Holder.

         (d)  Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by Holder, provided
that the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such states or jurisdictions or to agree to any restrictions as
to the conduct of its business in the ordinary course thereof.

         (e)  In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering.  Holder shall also enter
into and perform its obligations under such underwriting agreement.


                                          2
<PAGE>

         (f)  Notify Holder at any time when a prospectus relating to
Registrable Securities of Holder covered by such registration statement is
required to be delivered under the Act, of the happening of any event as a
result of which the prospectus included in such registration statement, as then
in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances under which they were
made.

         (g)  Furnish, at the request of Holder, on the date that such
Registrable Securities are delivered to the underwriters for sale in connection
with a registration pursuant to the Warrant, if such securities are being sold
through underwriters, or, if such securities are not being sold through
underwriters, on the date that the registration statement with respect to such
securities becomes effective, (i) an opinion, dated such date, of counsel
representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and to Holder and (ii) a letter
dated such date, from the independent certified public accountants of the
Company, in form and substance as is customarily given by independent certified
public accountants to underwriters in an underwritten public offering, addressed
to the underwriters, if any, and to Holder.

    5.   AVAILABILITY OF RULE 144.  Notwithstanding anything in the Warrant or
this Statement of Registration Rights to the contrary, the Company shall not be
obligated to effect any such registration, qualification or compliance, pursuant
to Section 2 or 3, if application of Rule 144 would allow Holder requesting a
registration under Section 2 or 3 to dispose of the Registrable Securities for
which a registration is demanded within a single 90-day period.

    6.   FURNISH INFORMATION.  It shall be a condition precedent to the
obligations of the Company to take any action pursuant to the Warrant that the
selling Holder shall furnish to the Company such information regarding itself,
the Registrable Securities held by Holder, and the intended method of
disposition of such securities as shall be required to effect the registration
of their Registrable Securities.

    7.   EXPENSES.  The Company shall bear and pay all expenses (other than
underwriting discounts and commissions) incurred in connection with any
registration, filing or qualification of Registrable Securities, including
(without limitation) all registration, filing, and qualification fees, legal,
printers and accounting fees relating thereto, and the cost of any reasonable
fees or disbursements of counsel for Holder.

    8.   UNDERWRITING REQUIREMENTS.  In connection with any registrations in
which Registrable Securities have a right to be included pursuant to Section 2
hereof and which involves an underwriting of securities being issued by the
Company, the Company shall not be required, under Section 2 hereof, to include
any of Holder's securities in such underwriting unless Holder accepts the terms
of the underwriting as agreed upon between the Company and the underwriters
selected by it, and then only in such quantity as will not, in the opinion of
the underwriters, jeopardize the success of the offering by the Company.  If the
total amount of securities, including Registrable Securities, requested by
stockholders to be included in such offering exceeds the amount of securities
sold other than by the Company that the underwriters reasonably believe
compatible with the success of the offering, then the Company shall be required
to include in the offering only that number of such securities, including
Registrable Securities, which the underwriters believe will not jeopardize the
success of the offering, the securities so included to be apportioned pro rata
among the selling Holder and other shareholders holding contractual registration
rights according to the total amount of securities entitled to be included
herein owned by each selling stockholder or in such other proportions as shall
mutually be agreed to by Holder and each other selling stockholder.


                                          3
<PAGE>

    9.   INDEMNIFICATION.  In the event any Registrable Securities are included
n a registration statement filed by the Company:

         (a)  The Company will indemnify and holder harmless Holder, its
officers, directors, and agents, any underwriter (as defined in the Act) for
Holder and each person, if any, who controls Holder or underwriter within the
meaning of the Act or the Securities Exchange Act of 1934, as amended (the "1934
Act"), against any losses, claims, damages, or liabilities (joint or several)
asserted by a third party to which they may become subject under the Act, the
1934 Act or other federal or state law, insofar as such losses, claims, damages,
or liabilities (or actions in respect thereof) arise out of or are based upon
any of the following statements, omissions or violations (collectively a
"Violation"):  (i) any untrue statement or alleged untrue statement of a
material fact contained in such registration statement, including any
preliminary prospectus or final prospectus contained therein or any amendments
or supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading, or (iii) any violation or alleged violation of the
Company of the Act, the 1934 Act, any state securities law or any rule or
regulation promulgated under the Act, the 1934 Act or any state securities law;
and the Company will reimburse Holder, any of its officers or directors,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them, as incurred, in connection with investigating or defending any
such loss, claim, damage, liability, or action; PROVIDED, HOWEVER, that the
indemnity agreement contained in this Section 9(a) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable in any such case
for any such loss, claim, damage, liability, or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by such Holder, underwriter or controlling person.

         (b)  Holder will indemnify and hold harmless the Company, each of its
directors, each of its officers who have signed the registration statement, each
person, if any, who controls the Company with the meaning of the Act, any
underwriter and any other shareholder selling securities in such registration
statement or any of its directors or officers or any person who controls such
shareholder, against any losses, claims, damages, or liabilities (joint or
several) asserted by a third party to which the Company or any such director,
officer, controlling person, or underwriter or controlling person, or other such
shareholder or director, officer or controlling person may become subject, under
the Act, the 1934 Act or other federal or state law, insofar as such losses,
claims, damages, or liabilities (or actions in respect thereto) arise out of or
are based upon any Violation, in each case to the extent (and only to the
extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by Holder expressly for use in connection with
such registration; and Holder will reimburse any legal or other expenses
reasonably incurred by the Company or any such director, officer, controlling
person, underwriter or controlling person, other shareholder, officer, director,
or controlling person, as incurred, in connection with investigating or
defending any such loss, claim, damage, liability, or action; PROVIDED, HOWEVER,
that the obligations of Holder hereunder shall be limited to an amount equal to
the net proceeds (equal to the offering price less the exercise price, expenses
and underwriting commissions and discounts) to such Holder of Shares sold as
contemplated herein.  Notwithstanding the foregoing, the indemnity agreement
contained in this Section 9(b) shall not apply to amounts paid in settlement of
any such loss, claim, damage, liability or action if such settlement is effected
without the consent of Holder, which consent shall not be unreasonably withheld.

         (c)  Promptly after receipt by an indemnified party under this
Section 9 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying part under this Section 9, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party


                                          4
<PAGE>

similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; PROVIDED, HOWEVER, that an indemnified party shall
have the right to  retain its own counsel, with the fees and expenses to be paid
by the  indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceeding.  The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to  defend such
action, shall relieve such indemnifying party of any liability to  the
indemnified party under this Section 9, but the omission so to deliver  written
notice to the indemnifying party will not relieve it of any liability  that it
may have to any indemnified party otherwise than under this Section 9.

    10.  REPORTS UNDER THE 1934 ACT.  With a view to making available to Holder
the benefits of Rule 144 promulgated under the Act and any other rule or
regulation of the SEC that may at any time permit Holder to sell securities of
the Company to the public without registration the Company will endeavor to:

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

         (b)  take such action as is necessary to enable Holder to utilize an
abbreviated registration statement for the sale of its Registrable Securities;

         (c)  file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and

         (d)  furnish to Holder, so long as Holder owns any Registrable
Securities, forthwith upon request (i) a written statement by the Company that
it has complied with the reporting requirements of SEC Rule 144, the Act and the
1934 Act, or that it qualifies as a registrant whose securities may be resold
pursuant to Form S-3 (at any time after it so qualifies), (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 in availing Holder of any rule or regulation of the SEC
which permits the selling of any such securities without registration or
pursuant to such form.

    11.  ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause the Company to
register Registrable Securities pursuant to the Warrant may be assigned by
Holder to a permitted transferee or assignee of the Warrant of all 150,000
Shares, provided the Company is, within a reasonable time after such transfer,
furnished with written notice of the name and address of such transferee or
assignee and the securities with respect to which such registration rights are
being assigned; and provided, further, that such assignment shall be effective
only if immediately following such transfer the further disposition of such
securities by the transferee or assignee is restricted under the Act.

payment to the Company of an amount equal to the product of the then 
applicable Warrant Price multiplied by the number of Shares then being 
purchased pursuant to one of the payment methods permitted under Section 4(b) 
below.
                    
           (b)  METHOD OF PAYMENT.  Payment shall be made either (1)

States funds for the account of the Company.
                    
           (c)  DELIVERY OF CERTIFICATE.  In the event of any exercise of the 
purchase right represented by this Warrant, certificates for the Shares so

<PAGE>

delivered to the Holder within five days of delivery of the Notice of 
Exercise and, unless this Warrant has been fully exercised or has expired, a 
new warrant representing the portion of the Shares with respect to which this 
Warrant shall not then have been exercised shall also be issued to the Holder 
within such ten day period.
                    
           (d)  NO FRACTIONAL SHARES.  No fractional shares shall be 
issued in connection with any exercise hereunder, but in lieu of such 
fractional shares the Company shall make a cash payment therefor upon the 
basis of the fair market value per Share as of the date of exercise.
                    
           (e)  COMPANY'S REPRESENTATIONS.
                    
           (i)  The Company is soliciting proxies in connection with its 
Annual Meeting of Stockholders for, among other things, a proposal to amend 
its Certificate of Incorporation to increase the number of shares of Common 
Stock authorized for issuance.  If such proposal is approved by the Company's 
stockholders, the Company shall file a Certificate of Amendment to its 
Certificate of Incorporation with the Secretary of State of the State of 
Delaware (the "Amendment") in order to increase such number of authorized 
shares of Common Stock.  From and after the date of filing the Amendment, all 
Shares which may be issued upon the exercise of the purchase right 
represented by this Warrant shall, upon issuance, be duly authorized, validly 
issued, fully paid and non-assessable, and free of any liens and encumbrances 
except for restrictions on transfer under applicable federal and state 
securities laws.  From and after the date of the Amendment, during the period 
within which the purchase right represented by this Warrant may be exercised, 
the Company shall at all times use its best efforts to have authorized, and 
reserved for the purpose of issuance upon exercise of the purchase right 
represented by this Warrant, a sufficient number of Shares to provide for the 
exercise of the purchase right represented by this Warrant;

           (ii) This Warrant has been duly authorized and executed by the 
Company and is a valid and binding obligation of the Company enforceable in 
accordance with its terms, subject to applicable bankruptcy, insolvency, 
reorganization, moratorium or other laws of general application affecting the 
enforcement of creditors' rights;
                         
           (iii)     The execution and delivery of this Warrant are not, and 
from and after the date of the Amendment, the issuance of the Shares upon 
exercise of this Warrant in accordance with the terms hereof will not be, 
inconsistent with the Company's Certificate of Incorporation or Bylaws, do 
not and will not contravene any law, governmental rule or regulation, 
judgment or order applicable to the Company, and do not and will not conflict 
with or contravene any provision of, or constitute a default under, any 
material indenture, mortgage, contract or other instrument of which the 
Company is a party or by which it is bound, or require the registration or 
filing with or the taking of any action in respect of or by, any federal, 
state or local government authority or agency (other than such consents, 
approvals, notices, actions, or filings as have already been obtained or 
made, as the case may be).

   5.   ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES.  The 
number of Shares issuable upon the exercise of this Warrant and the Warrant 
Price shall be subject to adjustment from time to time upon the occurrence of 
certain events, as follows:

           (a)  ADJUSTMENT FOR DIVIDENDS IN STOCK.  In case at any time or 
from time to time on or after the date hereof the holders of the Common Stock 
of the Company (or any shares of stock or other securities at the time 
receivable upon the exercise of this Warrant) shall have received or, on or 
after the record date fixed for the determination of eligible stockholders, 
shall have become entitled to receive, without payment therefor, other or 
additional stock of the Company by way of dividend then, and in each case, 
the Holder of this Warrant shall, upon the exercise hereof, be entitled to 
receive, in addition to the number of shares of Common Stock receivable 
thereupon, and without payment of any additional  consideration therefor, the 
amount of such other or additional stock of the Company which such Holder 
would hold on the date of such exercise had it been the holder of record of 
such Common Stock on the date hereof and had thereafter, during the period 
from the date hereof to and including the date of such exercise, retained 
such shares and/or all other additional stock receivable by it as aforesaid 
during such period, giving effect to all adjustments called for during such 
period by paragraphs (b) and (c) of this Section 5.
                    
           (b)  ADJUSTMENT FOR RECLASSIFICATION OR REORGANIZATION.  In case 
of any reclassification or change of the outstanding securities of the 
Company or of any consolidation, merger or reorganization of the Company on 
or after the date hereof, then and in each such case the Holder of this 
Warrant, upon the exercise hereof at any time after the consummation of such 
reclassification, change, consolidation, merger or reorganization, shall be 
entitled to receive, in lieu of or in addition to the stock or other 
securities and property receivable upon the exercise hereof prior to such 
consummation, the stock or other securities to which such Holder would have 
been entitled upon such consummation if such Holder had exercised this 
Warrant immediately prior thereto, all subject to further adjustment as 
provided in subparagraphs (a) and (c); in each such case, the terms of this 
Paragraph 5 shall be applicable to the shares of stock or other securities 
property receivable upon the exercise of this Warrant after such consummation.
                    
           (c)  STOCK SPLITS AND REVERSE STOCK SPLITS.  If, at any time on or 
after the date hereof, the Company shall subdivide its outstanding shares of 
Common Stock into a greater number of shares, the Warrant Price in effect 
immediately prior to such subdivision shall thereby be proportionately 
reduced and the number of shares receivable upon exercise of this Warrant 
shall thereby be proportionately increased; and, conversely, if at any time 
on or after the date hereof the outstanding number of shares of Common Stock 
shall be combined into a smaller number of shares, the Warrant Price in 
effect immediately prior to such combination shall thereby be proportionately 
increased and the number of shares receivable upon exercise of the Warrant 
shall be proportionately decreased.
                    
           (d)  ADJUSTMENTS TO WARRANT PRICE.  Whenever the number of Shares 
purchasable upon exercise of this Warrant is adjusted, as herein provided, 
the Warrant Price shall be adjusted by multiplying the Exercise Price in 
effect immediately prior to such

                                       4

<PAGE>

adjustment by a fraction, of which the numerator shall be the number of 
Shares purchasable upon the exercise of each Warrant immediately prior to 
such adjustment, and of which the denominator shall be the number of Shares 
so purchasable immediately thereafter.
                    
           (e)  CERTIFICATES AS TO ADJUSTMENTS.  Upon each adjustment of the 
Warrant Price, the Company at its expense shall promptly compute such 
adjustment, and furnish the Holder with a certificate of its Chief Financial 
Officer setting forth such adjustment and the facts upon which such 
adjustment is based.  The Company shall, upon written request, furnish the 
Holder a certificate setting forth the Warrant Price in effect upon the date 
thereof and the series of adjustments leading to such Warrant Price.

   6.   ACQUISITIONS.

           (a)  ASSUMPTION OF WARRANT.  If upon the closing of any 
Acquisition the successor entity assumes the obligations of this Warrant, 
then this Warrant shall be exercisable for the same securities, cash, and 
property as would be payable for the Shares issuable upon exercise of the 
unexercised portion of this Warrant as if such Shares were outstanding on the 
record date for the Acquisition and subsequent closing.
                    
           (b)  NONASSUMPTION.  If upon the closing of any Acquisition the 
successor entity does not assume the obligations of this Warrant and the 
Holder has not otherwise exercised this Warrant in full, then the unexercised 
portion of this Warrant shall be deemed to have been automatically converted 
pursuant to Section 4(c) and thereafter the Holder shall participate in the 
acquisition on the same terms as other holders of the same class of 
securities of the Company.

   7.   NOTICES; INFORMATION; REGISTRATION.

           (a)  NOTICE OF CERTAIN EVENTS.  If the Company proposes at any 
time (a) to effect any reclassification or recapitalization of Common Stock; 
(b) to merge or consolidate with or into any other corporation, or sell, 
lease, license, or convey all or substantially all of its assets, or to 
liquidate, dissolve or wind up; or (c) offer holders of registration rights 
the opportunity to participate in an underwritten public offering of the 
company's securities for cash, then, in connection with each such event, the 
Company shall give the Holder at least 14 days prior written notice of the 
date on which a record will be taken for such action.  
                    
           (b)  INFORMATION RIGHTS.  So long as the Holder holds this Warrant 
and/or any of the Shares, the Company shall deliver to the Holder (a) 
promptly after mailing, copies of all notices or other written communications 
to the stockholders of the Company, (b) within ninety days after the end of 
each fiscal year of the Company, the annual audited financial statements of 
the Company audited by independent public accountants of recognized standing 
and (c) within forty-five days after the end of each of the first three 
quarters of each fiscal year, the Company's quarterly, unaudited financial 
statements.

                                       5

<PAGE>

           (c)  REGISTRATION UNDER SECURITIES ACT OF 1933.  The Company 
agrees that the Shares shall be subject to the registration rights set forth 
on Exhibit B.

   8.   COMPLIANCE WITH ACT; TRANSFERABILITY AND NEGOTIABILITY OF WARRANT;    
            DISPOSITION OF SHARES.

           (a)  COMPLIANCE WITH ACT.  The Holder, by acceptance hereof, 
agrees that this Warrant and the Shares to be issued upon the exercise hereof 
are being acquired solely for its own account and not as a nominee for any 
other party and not with a view toward the resale or distribution thereof and 
that it will not offer, sell or otherwise dispose of this Warrant or any 
Shares to be issued upon the exercise hereof except under circumstances which 
will not result in a violation of the Act.  This Warrant and the Shares to be 
issued upon the exercise hereof (unless registered under the Act) shall be 
imprinted with a legend in substantially the following form:
                    
              THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED 
              UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE 
              SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS 
              AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT COVERING 
              SUCH SECURITIES, THE SALE IS MADE IN ACCORDANCE WITH RULE 144 
              UNDER THE ACT, OR THE COMPANY RECEIVES AN OPINION OF COUNSEL 
              FOR THE HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO 
              THE COMPANY, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR 
              HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS 
              DELIVERY REQUIREMENTS OF SUCH ACT.

In addition, this Warrant and the Shares to be issued upon the exercise 
hereof shall bear any legends required by the securities laws of any 
applicable states.

           (b)  TRANSFERABILITY AND NEGOTIABILITY OF WARRANT.  This Warrant 
may not be transferred or assigned in whole or in part without compliance 
with all applicable federal and state securities laws by the transferor and 
the transferee (including the delivery of investment representation letters 
and legal opinions satisfactory to the Company, if requested by the Company 
and the transfer is to a person other than a general partner or affiliate of 
the initial Holder).  Subject to the provisions of this Warrant with respect 
to compliance with the Act, title to this Warrant may be transferred by 
endorsement and delivery in the same manner as a negotiable instrument 
transferable by endorsement and delivery.  The Company shall act promptly to 
record transfers of this Warrant on its books, but the Company may treat the 
registered holder of this Warrant as the absolute owner of this Warrant for 
all purposes, notwithstanding any notice to the contrary.

                                       6
<PAGE>


           (c)  DISPOSITION OF SHARES.  With respect to any offer, sale, 
transfer or other disposition of any Shares acquired pursuant to the exercise 
of this Warrant prior to registration of such Shares, except for any such 
offer, sale, transfer or other disposition of Shares to an affiliate of the 
initial Holder, the Holder and each subsequent holder of this Warrant agrees 
to give written notice to the Company prior thereto, describing briefly the 
manner thereof, and if such transfer is not pursuant to Rule 144, a written 
opinion of legal counsel for such holder, if requested by the Company, to the 
effect that such offer, sale or other disposition may be effected without 
registration or qualification of such Shares.  Notwithstanding the foregoing, 
such Shares may be offered, sold or otherwise disposed of in accordance with 
Rule 144, provided that the Company shall have been furnished with such 
information as the Company may reasonably request to provide a reasonable 
assurance that the provisions of Rule 144 have been satisfied.  Each 
certificate representing the Shares thus transferred (except a transfer 
pursuant to Rule 144) shall bear a restrictive legend as to the applicable 
restrictions on transferability in order to insure compliance with the Act, 
unless in the aforesaid opinion of legal counsel for the holder, such legend 
is not required in order to insure compliance with the Act.

   9.   RIGHTS OF STOCKHOLDERS.  No Holder shall be entitled to vote or 
receive dividends or be deemed the holder of Shares or any other securities 
of the Company which may at any time be issuable on the exercise of this 
Warrant for any purpose, nor shall anything contained herein be construed to 
confer upon the Holder, as such, any of the rights of a stockholder of the 
Company or any right to vote for the election of directors or upon any matter 
submitted to stockholders at any meeting thereof, or to give or withhold 
consent to any corporate action (whether upon any recapitalization, issuance 
of stock, reclassification of stock, consolidation, merger, transfer of 
assets or otherwise) or, except as expressly required herein, to receive 
notice of meetings, or to receive dividends or subscription rights or 
otherwise until this Warrant shall have been exercised and the Shares 
issuable upon exercise hereof shall have become deliverable, as provided 
herein.

   10.  REPLACEMENT OF WARRANTS.  On receipt of evidence reasonably 
satisfactory to the Company of the loss, theft, destruction or mutilation of 
this Warrant and, in the case of loss, theft or destruction, on delivery of 
an indemnity agreement reasonably satisfactory in form and amount to the 
Company or, in the case of mutilation, on surrender and  cancellation of this 
Warrant, the Company at its expense shall execute and deliver, in lieu of 
this Warrant, a new warrant of like tenor.

   11.  EXCHANGE OF WARRANT.  Subject to the other provisions of this 
Warrant, on surrender of this Warrant for exchange, and subject to the 
provisions of this Warrant with respect to compliance with the Act, the 
Company at its expense shall issue to or on the order of the Holder a new 
warrant or warrants of like tenor, in the name of the Holder or as the Holder 
(on payment by the Holder of any applicable transfer taxes) may direct, for 
the number of Shares issuable upon exercise thereof.

   12.  NOTICES.  All notices and other communications from the Company to 
the Holder, or vice versa, shall be deemed delivered and effective when given 
personally or

                                       7

<PAGE>

mailed by first-class registered or certified mail, postage prepaid, at such 
address as may have been furnished to the Company or the Holder, as the case 
may be, in writing by the Company or such Holder from time to time.

   13.  WAIVER.  This Warrant and any term hereof may be changed, waived, 
discharged or terminated only by an instrument in writing signed by the party 
against which enforcement of such change, waiver, discharge or termination is 
sought.

   14.  GOVERNING LAW.  This Warrant shall be governed by and construed in 
accordance with the laws of the State of Delaware.

   15.  TITLES AND SUBTITLES; FORMS OF PRONOUNS.  The titles of the Sections 
and Subsections of this Warrant are for convenience only and are not to be 
considered in construing this Warrant.  All pronouns used in this Warrant 
shall be deemed to include masculine, feminine and neuter forms.
               
   16.  ATTORNEYS' FEES.  In the event of any dispute between the parties 
concerning the terms and provisions of this Warrant, the party prevailing in 
such dispute shall be entitled to collect from the other party all costs 
incurred in such dispute, including reasonable attorneys' fees.

                           STATEMENT OF REGISTRATION RIGHTS
                                           


     1.   DEFINITIONS.  For purposes of the Warrant to which this Statement of
Registration Rights is attached as Exhibit B:

          (a)  The terms "register," "registered," and "registration" refer 
to a registration effected by preparing and filing a registration statement 
or similar document in compliance with the Securities Act of 1933, as amended 
(the "Act"), and the declaration or ordering of effectiveness of such 
registration statement or document;
                    
           (b)  The term "Registrable Securities" means the shares of Common 
Stock issued or issuable upon exercise of the Warrant;
                    
           (c)  The term "Holder" means the original holder of the Warrant 
and any transferee of the Warrant; and
                    
           (d)  The term "Warrant" means the original Warrants issued in 
connection with the Stock and Warrant Purchase Agreement, dated as of October 
15, 1997, between the Company, as Seller, and Wexford Spectrum Investors LLC, 
a Delaware limited liability company, and Imprimis Investors LLC, a Delaware 
limited liability company, as Buyers, and all Warrants issued as a result of 
the transfer of such original Warrants.

   2.   COMPANY REGISTRATION.  If (but without any obligation to do so) the 
Company proposes at any time before October 15, 2002 to register (including 
for this purpose a registration effected by the Company for stockholders 
other than Holder) any of its stock or other securities under the Act in 
connection with the public offering for its own account of such securities 
solely for cash (other than a registration relating solely to the sale of 
securities to participants in a Company stock plan, or a registration on any 
form which does not include substantially the same information as would be 
required to be included in a registration statement covering the sale of the 
Registrable Securities), the Company shall, at such time, promptly give 
Holder written notice of such registration.  Upon the written request of 
Holder given within twenty days after mailing of such notice by the Company, 
the Company shall, subject to the provisions of Section 8 hereof and Section 
5 of the Warrant, cause to be registered under the Act all of the Registrable 
Securities that each such Holder has requested to be registered.

   3.   DEMAND REGISTRATION.  In case the Company shall, at any time before 
October 15, 2002, receive from Holders holding 40% or more of the outstanding 
Registrable Securities a written request (to be exercised only once) that the 
Company effect a registration and any related qualification or compliance 
with respect to all or a part of the Registrable Securities (which 
registration shall at the election of Holder either be for a registration for 
a primary issuance of the Shares upon the exercise of the Warrant or the 
resale of the Shares previously issued upon exercise of the Warrant at the 
election of Holder) owned by such Holder, the Company will promptly notify 
each other Holder (if any) of such request and will:


<PAGE>

           (a)  as soon as practicable, effect such registration and all such 
qualifications and compliances as may be so requested and as would permit or 
facilitate the sale and distribution of all or such portion of a Holder's 
Registrable Securities as are specified in such request, together with all or 
such portion of the Registrable Securities of any other holder of 
registration rights joining in such request as are specified in a written 
request given within 20 days after receipt of such written notice from the 
Company; PROVIDED, HOWEVER, that the Company shall not be obligated to effect 
any such registration, qualification or compliance, pursuant to this Section 
3:  (1) if the Company has effected a registration of Registrable Securities 
pursuant to this Section 3 within the preceding 12 months; (2) if the Company 
shall furnish to Holder a certificate signed by the President of the Company 
stating that in the good faith judgment of the Board of Directors of the 
Company, it would be seriously detrimental to the Company and its 
stockholders for such registration to be effected at such time, in which 
event the Company shall have the right to defer the filing of the 
registration statement for a period of not more than 60 days after receipt of 
the request of Holder under this Section 3; PROVIDED, HOWEVER, that the 
Company shall not utilize this right more than once in any twelve-month 
period; or (3) in any jurisdiction in which the Company would be required to 
qualify to do business or to execute a general consent to service of process 
in effecting such registration, qualification or compliance; and,
                    
           (b)  subject to the foregoing, file a registration statement 
covering the Registrable Securities and other securities so requested to be 
registered promptly after receipt of the request or requests of Holder, and 
in any event within 30 days of receipt of such request.
                    
   4.   OBLIGATION OF THE COMPANY.  Subject to the terms of the Warrant, in
the event that the Company is to effect the registration of any Registrable
Securities pursuant to Section 2 or 3 hereof, the Company shall promptly:

           (a)  Prepare and file with the SEC a registration statement with 
respect to such Registrable Securities and use its best efforts to cause such 
registration statement to become effective, and, upon the request of the 
holders of a majority of the securities registered thereunder, keep such 
registration statement effective for up to one hundred twenty (120) days, or 
such shorter period as is required to dispose of all securities covered by 
such registration statement.

           (b)  Prepare and file with the SEC such amendments and supplements 
to such registration statement and the prospectus used in connection with 
such registration statement as may be necessary to comply with the provisions 
of the Act with respect to the disposition of all securities covered by such 
registration statement.

           (c)  Furnish to Holder such number of copies of a prospectus, 
including a preliminary prospectus, in conformity with the requirements of 
the Act, and such other documents as Holder may reasonably request in order 
to facilitate the disposition of Registrable Securities owned by Holder.
                    
           (d)  Use its best efforts to register and qualify the securities 
covered by such registration statement under such other securities or Blue 
Sky laws of such jurisdictions as shall be reasonably requested by Holder, 
provided that the Company shall not be required in connection therewith or as 
a condition thereto to qualify to do business or to file a general consent to 
service of process in any such states or jurisdictions or to agree to any 
restrictions as to the conduct of its business in the ordinary course thereof.
                    
           (e)  In the event of any underwritten public offering, enter into 
and perform its obligations under an underwriting agreement, in usual and 
customary form, with the managing underwriter of such offering.  Holder shall 
also enter into and perform its obligations under such underwriting agreement.


                                       2

<PAGE>

           (f)  Notify Holder at any time when a prospectus relating to 
Registrable Securities of Holder covered by such registration statement is 
required to be delivered under the Act, of the happening of any event as a 
result of which the prospectus included in such registration statement, as 
then in effect, includes an untrue statement of a material fact or omits to 
state a material fact required to be stated therein or necessary to make the 
statements therein not misleading in the light of the circumstances under 
which they were made.
                    
           (g)  Furnish, at the request of Holder, on the date that such 
Registrable Securities are delivered to the underwriters for sale in 
connection with a registration pursuant to the Warrant, if such securities 
are being sold through underwriters, or, if such securities are not being 
sold through underwriters, on the date that the registration statement with 
respect to such securities becomes effective, (i) an opinion, dated such 
date, of counsel representing the Company for the purposes of such 
registration, in form and substance as is customarily given to underwriters 
in an underwritten public offering, addressed to the underwriters, if any, 
and to Holder and (ii) a letter dated such date, from the independent 
certified public accountants of the Company, in form and substance as is 
customarily given by independent certified public accountants to underwriters 
in an underwritten public offering, addressed to the underwriters, if any, 
and to Holder.

   5.   AVAILABILITY OF RULE 144.  Notwithstanding anything in the Warrant or 
this Statement of Registration Rights to the contrary, the Company shall not 
be obligated to effect any such registration, qualification or compliance, 
pursuant to Section 2 or 3, if application of Rule 144 would allow Holder 
requesting a registration under Section 2 or 3 to dispose of the Registrable 
Securities for which a registration is demanded within a single 90-day period.

   6.   FURNISH INFORMATION.  It shall be a condition precedent to the 
obligations of the Company to take any action pursuant to the Warrant that 
the selling Holder shall furnish to the Company such information regarding 
itself, the Registrable Securities held by Holder, and the intended method of 
disposition of such securities as shall be required to effect the 
registration of their Registrable Securities.

   7.   EXPENSES.  The Company shall bear and pay all expenses (other than 
underwriting discounts and commissions) incurred in connection with any 
registration, filing or qualification of Registrable Securities, including 
(without limitation) all registration, filing, and qualification fees, legal, 
printers and accounting fees relating thereto, and the cost of any reasonable 
fees or disbursements of counsel for Holder.

   8.   UNDERWRITING REQUIREMENTS.  In connection with any registrations in 
which Registrable Securities have a right to be included pursuant to Section 
2 hereof and which involves an underwriting of securities being issued by the 
Company, the Company shall not be required, under Section 2 hereof, to 
include any of Holder's securities in such underwriting unless Holder accepts 
the terms of the underwriting as agreed upon between the Company and the 
underwriters selected by it, and then only in such quantity as will not, in 
the opinion of the underwriters, jeopardize the success of the offering by 
the Company.  If the total amount of securities, including Registrable 
Securities, requested by stockholders to be included in such offering exceeds 
the amount of securities sold other than by the Company that the underwriters 
reasonably believe compatible with the success of the offering, then the 
Company shall be required to include in the offering only that number of such 
securities, including Registrable Securities, which the underwriters believe 
will not jeopardize the success of the offering, the securities so included 
to be apportioned pro rata among the selling Holder and other shareholders 
holding contractual registration rights according to the total amount of 
securities entitled to be included herein owned by each selling stockholder 
or in such other proportions as shall mutually be agreed to by Holder and 
each other selling stockholder.

                                       3

   9.   INDEMNIFICATION.  In the event any Registrable Securities are 
included n a registration statement filed by the Company:

           (a)  The Company will indemnify and holder harmless Holder, its 
officers, directors, and agents, any underwriter (as defined in the Act) for 
Holder and each person, if any, who controls Holder or underwriter within the 
meaning of the Act or the Securities Exchange Act of 1934, as amended (the 
"1934 Act"), against any losses, claims, damages, or liabilities (joint or 
several) asserted by a third party to which they may become subject under the 
Act, the 1934 Act or other federal or state law, insofar as such losses, 
claims, damages, or liabilities (or actions in respect thereof) arise out of 
or are based upon any of the following statements, omissions or violations 
(collectively a "Violation"):  (i) any untrue statement or alleged untrue 
statement of a material fact contained in such registration statement, 
including any preliminary prospectus or final prospectus contained therein or 
any amendments or supplements thereto, (ii) the omission or alleged omission 
to state therein a material fact required to be stated therein, or necessary 
to make the statements therein not misleading, or (iii) any violation or 
alleged violation of the Company of the Act, the 1934 Act, any state 
securities law or any rule or regulation promulgated under the Act, the 1934 
Act or any state securities law; and the Company will reimburse Holder, any 
of its officers or directors, underwriter or controlling person for any legal 
or other expenses reasonably incurred by them, as incurred, in connection 
with investigating or defending any such loss, claim, damage, liability, or 
action; PROVIDED, HOWEVER, that the indemnity agreement contained in this 
Section 9(a) shall not apply to amounts paid in settlement of any such loss, 
claim, damage, liability or action if such settlement is effected without the 
consent of the Company (which consent shall not be unreasonably withheld), 
nor shall the Company be liable in any such case for any such loss, claim, 
damage, liability, or action to the extent that it arises out of or is based 
upon a Violation which occurs in reliance upon and in conformity with written 
information furnished expressly for use in connection with such registration 
by such Holder, underwriter or controlling person.
                    
           (b)  Holder will indemnify and hold harmless the Company, each of 
its directors, each of its officers who have signed the registration 
statement, each person, if any, who controls the Company with the meaning of 
the Act, any underwriter and any other shareholder selling securities in such 
registration statement or any of its directors or officers or any person who 
controls such shareholder, against any losses, claims, damages, or 
liabilities (joint or several) asserted by a third party to which the Company 
or any such director, officer, controlling person, or underwriter or 
controlling person, or other such shareholder or director, officer or 
controlling person may become subject, under the Act, the 1934 Act or other 
federal or state law, insofar as such losses, claims, damages, or liabilities 
(or actions in respect thereto) arise out of or are based upon any Violation, 
in each case to the extent (and only to the extent) that such Violation 
occurs in reliance upon and in conformity with written information furnished 
by Holder expressly for use in connection with such registration; and Holder 
will reimburse any legal or other expenses reasonably incurred by the Company 
or any such director, officer, controlling person, underwriter or controlling 
person, other shareholder, officer, director, or controlling person, as 
incurred, in connection with investigating or defending any such loss, claim, 
damage, liability, or action; PROVIDED, HOWEVER, that the obligations of 
Holder hereunder shall be limited to an amount equal to the net proceeds 
(equal to the offering price less the exercise price, expenses and 
underwriting commissions and discounts) to such Holder of Shares sold as 
contemplated herein.  Notwithstanding the foregoing, the indemnity agreement 
contained in this Section 9(b) shall not apply to amounts paid in settlement 
of any such loss, claim, damage, liability or action if such settlement is 
effected without the consent of Holder, which consent shall not be 
unreasonably withheld.
                    
           (c)  Promptly after receipt by an indemnified party under this 
Section 9 of notice of the commencement of any action (including any 
governmental action), such indemnified party will, if a claim in respect 
thereof is to be made against any indemnifying part under this Section 9, 
deliver to the indemnifying party a written notice of the commencement 
thereof and the indemnifying party shall have the right to participate in, 
and, to the extent the indemnifying party so desires, jointly with any other 
indemnifying party


                                       4

<PAGE>

similarly noticed, to assume the defense thereof with counsel mutually 
satisfactory to the parties; PROVIDED, HOWEVER, that an indemnified party 
shall have the right to  retain its own counsel, with the fees and expenses 
to be paid by the  indemnifying party, if representation of such indemnified 
party by the counsel retained by the indemnifying party would be 
inappropriate due to actual or potential differing interests between such 
indemnified party and any other party represented by such counsel in such 
proceeding.  The failure to deliver written notice to the indemnifying party 
within a reasonable time of the commencement of any such action, if 
prejudicial to its ability to  defend such action, shall relieve such 
indemnifying party of any liability to  the indemnified party under this 
Section 9, but the omission so to deliver  written notice to the indemnifying 
party will not relieve it of any liability  that it may have to any 
indemnified party otherwise than under this Section 9.

   10.  REPORTS UNDER THE 1934 ACT.  With a view to making available to 
Holder the benefits of Rule 144 promulgated under the Act and any other rule 
or regulation of the SEC that may at any time permit Holder to sell 
securities of the Company to the public without registration the Company will 
endeavor to:

           (a)  make and keep public information available, as those terms 
are understood and defined in SEC Rule 144;
                    
           (b)  take such action as is necessary to enable Holder to utilize 
an abbreviated registration statement for the sale of its Registrable 
Securities;
                    
           (c)  file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and
                    
           (d)  furnish to Holder, so long as Holder owns any Registrable 
Securities, forthwith upon request (i) a written statement by the Company 
that it has complied with the reporting requirements of SEC Rule 144, the Act 
and the 1934 Act, or that it qualifies as a registrant whose securities may 
be resold pursuant to Form S-3 (at any time after it so qualifies), (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 in availing Holder of any rule or 
regulation of the SEC which permits the selling of any such securities 
without registration or pursuant to such form.

   11.  ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause the Company 
to register Registrable Securities pursuant to the Warrant may be assigned by 
Holder to a permitted transferee or assignee of the Warrant of all 150,000 
Shares, provided the Company is, within a reasonable time after such 
transfer, furnished with written notice of the name and address of such 
transferee or assignee and the securities with respect to which such 
registration rights are being assigned; and provided, further, that such 
assignment shall be effective only if immediately following such transfer the 
further disposition of such securities by the transferee or assignee is 
restricted under the Act.

          (e)  COMPANY'S REPRESENTATIONS.
                    
               (i)  The Company is soliciting proxies in connection with its 
Annual Meeting of Stockholders for, among other things, a proposal to amend 
its Certificate of Incorporation to increase the number of shares of Common 
Stock authorized for issuance.  If such proposal is approved by the Company's 
stockholders, the Company shall file a Certificate of Amendment to its 
Certificate of Incorporation with the Secretary of State of the State of 
Delaware (the "Amendment") in order to increase such number of authorized 
shares of Common Stock.  From and after the date of filing the Amendment, all 
Shares which may be issued upon the exercise of the purchase right

issued, fully paid and non-assessable, and free of any liens and encumbrances

and from and after the date of the Amendment, the issuance of the Shares upon 
exercise of this Warrant in accordance with the terms hereof will not be, 
inconsistent with the Company's Certificate of Incorporation or Bylaws, do 
not and will not contravene any law, governmental rule or regulation, 
judgment or order applicable to the Company, and do not and will not conflict 
with or contravene any provision of, or constitute a default under, any 
material indenture, mortgage, contract or other instrument of which the 
Company is a party or by which it is bound, or require the registration or 
filing with or the taking of any action in respect of or by, any federal, 
state or local government authority or agency (other than such consents, 
approvals, notices, actions, or filings as have already been obtained or 
made, as the case may be).

     5.   ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES.  The number of 
Shares issuable upon the exercise of this Warrant and the Warrant Price shall 
be subject to adjustment from time to time upon the occurrence of certain 
events, as follows:

          (a)  ADJUSTMENT FOR DIVIDENDS IN STOCK.  In case at any time or 
from time to time on or after the date hereof the holders of the Common Stock 
of the Company (or any shares of stock or other securities at the time 
receivable upon the exercise of this Warrant) shall have received or, on or 
after the record date fixed for the determination of eligible stockholders, 
shall have become entitled to receive, without payment therefor, other or 
additional stock of the Company by way of dividend then, and in each case, 
the Holder of this Warrant shall, upon the exercise hereof, be entitled to 
receive, in addition to the number of shares of Common Stock receivable 
thereupon, and without payment of any additional  consideration therefor, the 
amount of such other or additional stock of the Company which such Holder 
would hold on the date of such exercise had it been the holder of record of 
such Common Stock on the date hereof and had thereafter, during the period 
from the date hereof to and including the date of such exercise, retained 
such shares and/or all other additional stock receivable by it as aforesaid 
during such period, giving effect to all adjustments called for during such 
period by paragraphs (b) and (c) of this Section 5.
                    
          (b)  ADJUSTMENT FOR RECLASSIFICATION OR REORGANIZATION.  In case of 
any reclassification or change of the outstanding securities of the Company 
or of any consolidation, merger or reorganization of the Company on or after 
the date hereof, then and in each such case the Holder of this Warrant, upon 
the exercise hereof at any time after the consummation of such 
reclassification, change, consolidation, merger or reorganization, shall be 
entitled to receive, in lieu of or in addition to the stock or other 
securities and property receivable upon the exercise hereof prior to such 
consummation, the stock or other securities to which such Holder would have 
been entitled upon such consummation if such Holder had exercised this 
Warrant immediately prior thereto, all subject to further adjustment as 
provided in subparagraphs (a) and (c); in each such case, the terms of this 
Paragraph 5 shall be applicable to the shares of stock or other securities 
property receivable upon the exercise of this Warrant after such consummation.
                    
          (c)  STOCK SPLITS AND REVERSE STOCK SPLITS.  If, at any time on or 
after the date hereof, the Company shall subdivide its outstanding shares of 
Common Stock into a greater number of shares, the Warrant Price in effect 
immediately prior to such subdivision shall thereby be proportionately 
reduced and the number of shares receivable upon exercise of this Warrant 
shall thereby be proportionately increased; and, conversely, if at any time 
on or after the date hereof the outstanding number of shares of Common Stock 
shall be combined into a smaller number of shares, the Warrant Price in 
effect immediately prior to such combination shall thereby be proportionately 
increased and the number of shares receivable upon exercise of the Warrant 
shall be proportionately decreased.
                    
          (d)  ADJUSTMENTS TO WARRANT PRICE.  Whenever the number of Shares 
purchasable upon exercise of this Warrant is adjusted, as herein provided, 
the Warrant Price shall be adjusted by multiplying the Exercise Price in 
effect immediately prior to such 

                                       4
<PAGE>

adjustment by a fraction, of which the numerator shall be the number of 
Shares purchasable upon the exercise of each Warrant immediately prior to 
such adjustment, and of which the denominator shall be the number of Shares 
so purchasable immediately thereafter.
                    
          (e)  CERTIFICATES AS TO ADJUSTMENTS.  Upon each adjustment of the 
Warrant Price, the Company at its expense shall promptly compute such 
adjustment, and furnish the Holder with a certificate of its Chief Financial 
Officer setting forth such adjustment and the facts upon which such 
adjustment is based.  The Company shall, upon written request, furnish the 
Holder a certificate setting forth the Warrant Price in effect upon the date 
thereof and the series of adjustments leading to such Warrant Price.

     6.   ACQUISITIONS.

          (a)  ASSUMPTION OF WARRANT.  If upon the closing of any Acquisition 
the successor entity assumes the obligations of this Warrant, then this 
Warrant shall be exercisable for the same securities, cash, and property as 
would be payable for the Shares issuable upon exercise of the unexercised 
portion of this Warrant as if such Shares were outstanding on the record date 
for the Acquisition and subsequent closing.
                    
          (b)  NONASSUMPTION.  If upon the closing of any Acquisition the 
successor entity does not assume the obligations of this Warrant and the 
Holder has not otherwise exercised this Warrant in full, then the unexercised 
portion of this Warrant shall be deemed to have been automatically converted 
pursuant to Section 4(c) and thereafter the Holder shall participate in the 
acquisition on the same terms as other holders of the same class of 
securities of the Company.

     7.   NOTICES; INFORMATION; REGISTRATION.

          (a)  NOTICE OF CERTAIN EVENTS.  If the Company proposes at any time 
(a) to effect any reclassification or recapitalization of Common Stock; (b) 
to merge or consolidate with or into any other corporation, or sell, lease, 
license, or convey all or substantially all of its assets, or to liquidate, 
dissolve or wind up; or (c) offer holders of registration rights the 
opportunity to participate in an underwritten public offering of the 
company's securities for cash, then, in connection with each such event, the 
Company shall give the Holder at least 14 days prior written notice of the 
date on which a record will be taken for such action.  
                    
          (b)  INFORMATION RIGHTS.  So long as the Holder holds this Warrant 
and/or any of the Shares, the Company shall deliver to the Holder (a) 
promptly after mailing, copies of all notices or other written communications

each fiscal year of the Company, the annual audited financial statements of

          (c)  REGISTRATION UNDER SECURITIES ACT OF 1933.  The Company agrees 
that the Shares shall be subject to the registration rights set forth on 
Exhibit B.

     8.   COMPLIANCE WITH ACT; TRANSFERABILITY AND NEGOTIABILITY OF WARRANT; 
          DISPOSITION OF SHARES.

          (a)  COMPLIANCE WITH ACT.  The Holder, by acceptance hereof, agrees 
that this Warrant and the Shares to be issued upon the exercise hereof are 
being acquired solely for its own account and not as a nominee for any other 
party and not with a view toward the resale or distribution thereof and that 
it will not offer, sell or otherwise dispose of this Warrant or any Shares to 
be issued upon the exercise hereof except under circumstances which will not 
result in a violation of the Act.  This Warrant and the Shares to be issued 
upon the exercise hereof (unless registered under the Act) shall be imprinted 
with a legend in substantially the following form:
                    
          THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN 
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, 
          AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED OR 
          HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION 
          STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE 
          SALE IS MADE IN ACCORDANCE WITH RULE 144 UNDER THE ACT, 
          OR THE COMPANY RECEIVES AN OPINION OF COUNSEL FOR THE 
          HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO THE 
          COMPANY, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR 
          HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND 
          PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

In addition, this Warrant and the Shares to be issued upon the exercise 
hereof shall bear any legends required by the securities laws of any 
applicable states.

          (b)  TRANSFERABILITY AND NEGOTIABILITY OF WARRANT.  This Warrant 
may not be transferred or assigned in whole or in part without compliance 
with all applicable federal and state securities laws by the transferor and 
the transferee (including the delivery of investment representation letters 
and legal opinions satisfactory to the Company, if requested by the Company 
and the transfer is to a person other than a general partner or affiliate of 
the initial Holder).  Subject to the provisions of this Warrant with respect 
to compliance with the Act, title to this Warrant may be transferred by 
endorsement and delivery in the same manner as a negotiable instrument 
transferable by endorsement and delivery.  The Company shall act promptly to 
record transfers of this Warrant on its books, but the Company may treat the 
registered holder of this Warrant as the absolute owner of this Warrant for 
all purposes, notwithstanding any notice to the contrary.

                                       6
<PAGE>

          (c)  DISPOSITION OF SHARES.  With respect to any offer, sale, 
transfer or other disposition of any Shares acquired pursuant to the exercise 
of this Warrant prior to registration of such Shares, except for any such 
offer, sale, transfer or other disposition of Shares to an affiliate of the 
initial Holder, the Holder and each subsequent holder of this Warrant agrees 
to give written notice to the Company prior thereto, describing briefly the 
manner thereof, and if such transfer is not pursuant to Rule 144, a written 
opinion of legal counsel for such holder, if requested by the Company, to the 
effect that such offer, sale or other disposition may be effected without 
registration or qualification of such Shares.  Notwithstanding the foregoing, 
such Shares may be offered, sold or otherwise disposed of in accordance with 
Rule 144, provided that the Company shall have been furnished with such 
information as the Company may reasonably request to provide a reasonable 
assurance that the provisions of Rule 144 have been satisfied.  Each 
certificate representing the Shares thus transferred (except a transfer 
pursuant to Rule 144) shall bear a restrictive legend as to the applicable 
restrictions on transferability in order to insure compliance with the Act, 
unless in the aforesaid opinion of legal counsel for the holder, such legend 
is not required in order to insure compliance with the Act.

     9.   RIGHTS OF STOCKHOLDERS.  No Holder shall be entitled to vote or 
receive dividends or be deemed the holder of Shares or any other securities 
of the Company which may at any time be issuable on the exercise of this 
Warrant for any purpose, nor shall anything contained herein be construed to 
confer upon the Holder, as such, any of the rights of a stockholder of the 
Company or any right to vote for the election of directors or upon any matter 
submitted to stockholders at any meeting thereof, or to give or withhold 
consent to any corporate action (whether upon any recapitalization, issuance 
of stock, reclassification of stock, consolidation, merger, transfer of 
assets or otherwise) or, except as expressly required herein, to receive 
notice of meetings, or to receive dividends or subscription rights or 
otherwise until this Warrant shall have been exercised and the Shares 
issuable upon exercise hereof shall have become deliverable, as provided 
herein.

     10.  REPLACEMENT OF WARRANTS.  On receipt of evidence reasonably 
satisfactory to the Company of the loss, theft, destruction or mutilation of 
this Warrant and, in the case of loss, theft or destruction, on delivery of 
an indemnity agreement reasonably satisfactory in form and amount to the 
Company or, in the case of mutilation, on surrender and  cancellation of this 
Warrant, the Company at its expense shall execute and deliver, in lieu of 
this Warrant, a new warrant of like tenor.

     11.  EXCHANGE OF WARRANT.  Subject to the other provisions of this 
Warrant, on surrender of this Warrant for exchange, and subject to the 
provisions of this Warrant with respect to compliance with the Act, the 
Company at its expense shall issue to or on the order of the Holder a new 
warrant or warrants of like tenor, in the name of the Holder or as the Holder 
(on payment by the Holder of any applicable transfer taxes) may direct, for 
the number of Shares issuable upon exercise thereof.

     12.  NOTICES.  All notices and other communications from the Company to 
the Holder, or vice versa, shall be deemed delivered and effective when given 
personally or 

                                       7
<PAGE>

mailed by first-class registered or certified mail, postage prepaid, at such 
address as may have been furnished to the Company or the Holder, as the case 
may be, in writing by the Company or such Holder from time to time.

     13.  WAIVER.  This Warrant and any term hereof may be changed, waived, 
discharged or terminated only by an instrument in writing signed by the party 
against which enforcement of such change, waiver, discharge or termination is 
sought.

     14.  GOVERNING LAW.  This Warrant shall be governed by and construed in 
accordance with the laws of the State of Delaware.

     15.  TITLES AND SUBTITLES; FORMS OF PRONOUNS.  The titles of the 
Sections and Subsections of this Warrant are for convenience only and are not 
to be considered in construing this Warrant.  All pronouns used in this 
Warrant shall be deemed to include masculine, feminine and neuter forms.
     
     16.  ATTORNEYS' FEES.  In the event of any dispute between the parties 
concerning the terms and provisions of this Warrant, the party prevailing in 
such dispute shall be entitled to collect from the other party all costs 
incurred in such dispute, including reasonable attorneys' fees.

                       STATEMENT OF REGISTRATION RIGHTS
                                       


     1.  DEFINITIONS.  For purposes of the Warrant to which this Statement of 
Registration Rights is attached as Exhibit B:

         (a)  The terms "register," "registered," and "registration" refer to 
a registration effected by preparing and filing a registration statement or 
similar document in compliance with the Securities Act of 1933, as amended 
(the "Act"), and the declaration or ordering of effectiveness of such 
registration statement or document;
                    
         (b)  The term "Registrable Securities" means the shares of Common 
Stock issued or issuable upon exercise of the Warrant;
                    
         (c)  The term "Holder" means the original holder of the Warrant and 
any transferee of the Warrant; and
                    
         (d)  The term "Warrant" means the original Warrants issued in 
connection with the Stock and Warrant Purchase Agreement, dated as of October 
15, 1997, between the Company, as Seller, and Wexford Spectrum Investors LLC, 
a Delaware limited liability company, and Imprimis Investors LLC, a Delaware 
limited liability company, as Buyers, and all Warrants issued as a result of 
the transfer of such original Warrants.

     2.  COMPANY REGISTRATION.  If (but without any obligation to do so) the 
Company proposes at any time before October 15, 2002 to register (including 
for this purpose a registration effected by the Company for stockholders 
other than Holder) any of its stock or other securities under the Act in 
connection with the public offering for its own account of such securities 
solely for cash (other than a registration relating solely to the sale of 
securities to participants in a Company stock plan, or a registration on any 
form which does not include substantially the same information as would be 
required to be included in a registration statement covering the sale of the 
Registrable Securities), the Company shall, at such time, promptly give 
Holder written notice of such registration.  Upon the written request of 
Holder given within twenty days after mailing of such notice by the Company, 
the Company shall, subject to the provisions of Section 8 hereof and Section 
5 of the Warrant, cause to be registered under the Act all of the Registrable 
Securities that each such Holder has requested to be registered.

     3.  DEMAND REGISTRATION.  In case the Company shall, at any time before 
October 15, 2002, receive from Holders holding 40% or more of the outstanding 
Registrable Securities a written request (to be exercised only once) that the 
Company effect a registration and any related qualification or compliance 
with respect to all or a part of the Registrable Securities (which 
registration shall at the election of Holder either be for a registration for 
a primary issuance of the Shares upon the exercise of the Warrant or the 
resale of the Shares previously issued upon exercise of the Warrant at the 
election of Holder) owned by such Holder, the Company will promptly notify 
each other Holder (if any) of such request and will:

<PAGE>

         (a)  as soon as practicable, effect such registration and all such 
qualifications and compliances as may be so requested and as would permit or 
facilitate the sale and distribution of all or such portion of a Holder's 
Registrable Securities as are specified in such request, together with all or 
such portion of the Registrable Securities of any other holder of 
registration rights joining in such request as are specified in a written 
request given within 20 days after receipt of such written notice from the 
Company; PROVIDED, HOWEVER, that the Company shall not be obligated to effect 
any such registration, qualification or compliance, pursuant to this Section 
3:  (1) if the Company has effected a registration of Registrable Securities 
pursuant to this Section 3 within the preceding 12 months; (2) if the Company 
shall furnish to Holder a certificate signed by the President of the Company 
stating that in the good faith judgment of the Board of Directors of the 
Company, it would be seriously detrimental to the Company and its 
stockholders for such registration to be effected at such time, in which 
event the Company shall have the right to defer the filing of the 
registration statement for a period of not more than 60 days after receipt of 
the request of Holder under this Section 3; PROVIDED, HOWEVER, that the 
Company shall not utilize this right more than once in any twelve-month 
period; or (3) in any jurisdiction in which the Company would be required to 
qualify to do business or to execute a general consent to service of process 
in effecting such registration, qualification or compliance; and,
                    
         (b)  subject to the foregoing, file a registration statement 
covering the Registrable Securities and other securities so requested to be 
registered promptly after receipt of the request or requests of Holder, and 
in any event within 30 days of receipt of such request.
                    
     4.  OBLIGATION OF THE COMPANY.  Subject to the terms of the Warrant, in 
the event that the Company is to effect the registration of any Registrable 
Securities pursuant to Section 2 or 3 hereof, the Company shall promptly:

         (a)  Prepare and file with the SEC a registration statement with 
respect to such Registrable Securities and use its best efforts to cause such 
registration statement to become effective, and, upon the request of the 
holders of a majority of the securities registered thereunder, keep such 
registration statement effective for up to one hundred twenty (120) days, or 
such shorter period as is required to dispose of all securities covered by 
such registration statement.

         (b)  Prepare and file with the SEC such amendments and supplements 
to such registration statement and the prospectus used in connection with 
such registration statement as may be necessary to comply with the provisions 
of the Act with respect to the disposition of all securities covered by such 
registration statement.

         (c)  Furnish to Holder such number of copies of a prospectus, 
including a preliminary prospectus, in conformity with the requirements of 
the Act, and such other documents as Holder may reasonably request in order 
to facilitate the disposition of Registrable Securities owned by Holder.
                    
         (d)  Use its best efforts to register and qualify the securities 
covered by such registration statement under such other securities or Blue 
Sky laws of such jurisdictions as shall be reasonably requested by Holder, 
provided that the Company shall not be required in connection therewith or as 
a condition thereto to qualify to do business or to file a general consent to 
service of process in any such states or jurisdictions or to agree to any 
restrictions as to the conduct of its business in the ordinary course thereof.
                    
         (e)  In the event of any underwritten public offering, enter into 
and perform its obligations under an underwriting agreement, in usual and 
customary form, with the managing underwriter of such offering.  Holder shall 
also enter into and perform its obligations under such underwriting agreement.

                                       2
<PAGE>

         (f)  Notify Holder at any time when a prospectus relating to 
Registrable Securities of Holder covered by such registration statement is 
required to be delivered under the Act, of the happening of any event as a 
result of which the prospectus included in such registration statement, as 
then in effect, includes an untrue statement of a material fact or omits to 
state a material fact required to be stated therein or necessary to make the 
statements therein not misleading in the light of the circumstances under 
which they were made.
                    
         (g)  Furnish, at the request of Holder, on the date that such 
Registrable Securities are delivered to the underwriters for sale in 
connection with a registration pursuant to the Warrant, if such securities 
are being sold through underwriters, or, if such securities are not being 
sold through underwriters, on the date that the registration statement with 
respect to such securities becomes effective, (i) an opinion, dated such 
date, of counsel representing the Company for the purposes of such 
registration, in form and substance as is customarily given to underwriters 
in an underwritten public offering, addressed to the underwriters, if any, 
and to Holder and (ii) a letter dated such date, from the independent 
certified public accountants of the Company, in form and substance as is 
customarily given by independent certified public accountants to underwriters 
in an underwritten public offering, addressed to the underwriters, if any, 
and to Holder.

     5.  AVAILABILITY OF RULE 144.  Notwithstanding anything in the Warrant 
or this Statement of Registration Rights to the contrary, the Company shall 
not be obligated to effect any such registration, qualification or 
compliance, pursuant to Section 2 or 3, if application of Rule 144 would 
allow Holder requesting a registration under Section 2 or 3 to dispose of the 
Registrable Securities for which a registration is demanded within a single 
90-day period.

     6.  FURNISH INFORMATION.  It shall be a condition precedent to the 
obligations of the Company to take any action pursuant to the Warrant that 
the selling Holder shall furnish to the Company such information regarding 
itself, the Registrable Securities held by Holder, and the intended method of 
disposition of such securities as shall be required to effect the 
registration of their Registrable Securities.

     7.  EXPENSES.  The Company shall bear and pay all expenses (other than 
underwriting discounts and commissions) incurred in connection with any 
registration, filing or qualification of Registrable Securities, including 
(without limitation) all registration, filing, and qualification fees, legal, 
printers and accounting fees relating thereto, and the cost of any reasonable 
fees or disbursements of counsel for Holder.

     8.  UNDERWRITING REQUIREMENTS.  In connection with any registrations in 
which Registrable Securities have a right to be included pursuant to Section 
2 hereof and which involves an underwriting of securities being issued by the 
Company, the Company shall not be required, under Section 2 hereof, to 
include any of Holder's securities in such underwriting unless Holder accepts 
the terms of the underwriting as agreed upon between the Company and the 
underwriters selected by it, and then only in such quantity as will not, in 
the opinion of the underwriters, jeopardize the success of the offering by 
the Company.  If the total amount of securities, including Registrable 
Securities, requested by stockholders to be included in such offering exceeds 
the amount of securities sold other than by the Company that the underwriters 
reasonably believe compatible with the success of the offering, then the 
Company shall be required to include in the offering only that number of such 
securities, including Registrable Securities, which the underwriters believe 
will not jeopardize the success of the offering, the securities so included 
to be apportioned pro rata among the selling Holder and other shareholders 
holding contractual registration rights according to the total amount of 
securities entitled to be included herein owned by each selling stockholder 
or in such other proportions as shall mutually be agreed to by Holder and 
each other selling stockholder.

                                       3
<PAGE>

     9.  INDEMNIFICATION.  In the event any Registrable Securities are 
included n a registration statement filed by the Company:

         (a)  The Company will indemnify and holder harmless Holder, its 
officers, directors, and agents, any underwriter (as defined in the Act) for 
Holder and each person, if any, who controls Holder or underwriter within the 
meaning of the Act or the Securities Exchange Act of 1934, as amended (the 
"1934 Act"), against any losses, claims, damages, or liabilities (joint or 
several) asserted by a third party to which they may become subject under the 
Act, the 1934 Act or other federal or state law, insofar as such losses, 
claims, damages, or liabilities (or actions in respect thereof) arise out of 
or are based upon any of the following statements, omissions or violations 
(collectively a "Violation"):  (i) any untrue statement or alleged untrue 
statement of a material fact contained in such registration statement, 
including any preliminary prospectus or final prospectus contained therein or 
any amendments or supplements thereto, (ii) the omission or alleged omission 
to state therein a material fact required to be stated therein, or necessary 
to make the statements therein not misleading, or (iii) any violation or 
alleged violation of the Company of the Act, the 1934 Act, any state 
securities law or any rule or regulation promulgated under the Act, the 1934 
Act or any state securities law; and the Company will reimburse Holder, any 
of its officers or directors, underwriter or controlling person for any legal 
or other expenses reasonably incurred by them, as incurred, in connection 
with investigating or defending any such loss, claim, damage, liability, or 
action; PROVIDED, HOWEVER, that the indemnity agreement contained in this 
Section 9(a) shall not apply to amounts paid in settlement of any such loss, 
claim, damage, liability or action if such settlement is effected without the 
consent of the Company (which consent shall not be unreasonably withheld), 
nor shall the Company be liable in any such case for any such loss, claim, 
damage, liability, or action to the extent that it arises out of or is based 
upon a Violation which occurs in reliance upon and in conformity with written 
information furnished expressly for use in connection with such registration 
by such Holder, underwriter or controlling person.
                    
         (b)  Holder will indemnify and hold harmless the Company, each of 
its directors, each of its officers who have signed the registration 
statement, each person, if any, who controls the Company with the meaning of 
the Act, any underwriter and any other shareholder selling securities in such 
registration statement or any of its directors or officers or any person who 
controls such shareholder, against any losses, claims, damages, or 
liabilities (joint or several) asserted by a third party to which the Company 
or any such director, officer, controlling person, or underwriter or 
controlling person, or other such shareholder or director, officer or 
controlling person may become subject, under the Act, the 1934 Act or other 
federal or state law, insofar as such losses, claims, damages, or liabilities 
(or actions in respect thereto) arise out of or are based upon any Violation, 
in each case to the extent (and only to the extent) that such Violation 
occurs in reliance upon and in conformity with written information furnished 
by Holder expressly for use in connection with such registration; and Holder 
will reimburse any legal or other expenses reasonably incurred by the Company 
or any such director, officer, controlling person, underwriter or controlling 
person, other shareholder, officer, director, or controlling person, as 
incurred, in connection with investigating or defending any such loss, claim, 
damage, liability, or action; PROVIDED, HOWEVER, that the obligations of 
Holder hereunder shall be limited to an amount equal to the net proceeds 
(equal to the offering price less the exercise price, expenses and 
underwriting commissions and discounts) to such Holder of Shares sold as 
contemplated herein.  Notwithstanding the foregoing, the indemnity agreement 
contained in this Section 9(b) shall not apply to amounts paid in settlement 
of any such loss, claim, damage, liability or action if such settlement is 
effected without the consent of Holder, which consent shall not be 
unreasonably withheld.
                    
         (c)  Promptly after receipt by an indemnified party under this 
Section 9 of notice of the commencement of any action (including any 
governmental action), such indemnified party will, if a claim in respect 
thereof is to be made against any indemnifying part under this Section 9, 
deliver to the indemnifying party a written notice of the commencement 
thereof and the indemnifying party shall have the right to participate in, 
and, to the extent the indemnifying party so desires, jointly with any other 
indemnifying party 

                                       4
<PAGE>

similarly noticed, to assume the defense thereof with counsel mutually 
satisfactory to the parties; PROVIDED, HOWEVER, that an indemnified party 
shall have the right to  retain its own counsel, with the fees and expenses 
to be paid by the  indemnifying party, if representation of such indemnified 
party by the counsel retained by the indemnifying party would be 
inappropriate due to actual or potential differing interests between such 
indemnified party and any other party represented by such counsel in such 
proceeding.  The failure to deliver written notice to the indemnifying party 
within a reasonable time of the commencement of any such action, if 
prejudicial to its ability to  defend such action, shall relieve such 
indemnifying party of any liability to  the indemnified party under this 
Section 9, but the omission so to deliver  written notice to the indemnifying 
party will not relieve it of any liability  that it may have to any 
indemnified party otherwise than under this Section 9.

     10. REPORTS UNDER THE 1934 ACT.  With a view to making available to 
Holder the benefits of Rule 144 promulgated under the Act and any other rule 
or regulation of the SEC that may at any time permit Holder to sell 
securities of the Company to the public without registration the Company will 
endeavor to:

         (a)  make and keep public information available, as those terms are 
understood and defined in SEC Rule 144;
                    
         (b)  take such action as is necessary to enable Holder to utilize an 
abbreviated registration statement for the sale of its Registrable Securities;
                    
         (c)  file with the SEC in a timely manner all reports and other 
documents required of the Company under the Act and the 1934 Act; and
                    
         (d)  furnish to Holder, so long as Holder owns any Registrable 
Securities, forthwith upon request (i) a written statement by the Company 
that it has complied with the reporting requirements of SEC Rule 144, the Act 
and the 1934 Act, or that it qualifies as a registrant whose securities may 
be resold pursuant to Form S-3 (at any time after it so qualifies), (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 in availing Holder of any rule or 
regulation of the SEC which permits the selling of any such securities 
without registration or pursuant to such form.

     11. ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause the Company 
to register Registrable Securities pursuant to the Warrant may be assigned by 
Holder to a permitted transferee or assignee of the Warrant of all 150,000 
Shares, provided the Company is, within a reasonable time after such 
transfer, furnished with written notice of the name and address of such 
transferee or assignee and the securities with respect to which such 
registration rights are being assigned; and provided, further, that such 
assignment shall be effective only if immediately following such transfer the 
further disposition of such securities by the transferee or assignee is 
restricted under the Act.

inconsistent with the Company's Certificate of Incorporation or Bylaws, do not
and will not contravene any law, governmental rule or regulation, judgment or
order applicable to the Company, and do not and will not conflict with or
contravene any provision of, or constitute a default under, any material

    5.   ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES.  The number of
Shares issuable upon the exercise of this Warrant and the Warrant Price shall be
subject to adjustment from time to time upon the occurrence of certain events,
as follows:

         (a)  ADJUSTMENT FOR DIVIDENDS IN STOCK.  In case at any time or from
time to time on or after the date hereof the holders of the Common Stock of the
Company (or any shares of stock or other securities at the time receivable upon
the exercise of this Warrant) shall have received or, on or after the record
date fixed for the determination of eligible stockholders, shall have become
entitled to receive, without payment therefor, other or additional stock of the
Company by way of dividend then, and in each case, the Holder of this Warrant
shall, upon the exercise hereof, be entitled to receive, in addition to the
number of shares of Common Stock receivable thereupon, and without payment of
any additional  consideration therefor, the amount of such other or additional
stock of the Company which such Holder would hold on the date of such exercise
had it been the holder of record of such Common Stock on the date hereof and had
thereafter, during the period from the date hereof to and including the date of
such exercise, retained such shares and/or all other additional stock receivable
by it as aforesaid during such period, giving effect to all adjustments called
for during such period by paragraphs (b) and (c) of this Section 5.

         (b)  ADJUSTMENT FOR RECLASSIFICATION OR REORGANIZATION.  In case of
any reclassification or change of the outstanding securities of the Company or
of any consolidation, merger or reorganization of the Company on or after the
date hereof, then and in each such case the Holder of this Warrant, upon the
exercise hereof at any time after the consummation of such reclassification,
change, consolidation, merger or reorganization, shall be entitled to receive,
in lieu of or in addition to the stock or other securities and property
receivable upon the exercise hereof prior to such consummation, the stock or
other securities to which such Holder would have been entitled upon such
consummation if such Holder had exercised this Warrant immediately prior
thereto, all subject to further adjustment as provided in subparagraphs (a) and
(c); in each such case, the terms of this Paragraph 5 shall be applicable to the
shares of stock or other securities property receivable upon the exercise of
this Warrant after such consummation.

         (c)  STOCK SPLITS AND REVERSE STOCK SPLITS.  If, at any time on or
after the date hereof, the Company shall subdivide its outstanding shares of
Common Stock into a greater number of shares, the Warrant Price in effect
immediately prior to such subdivision shall thereby be proportionately reduced
and the number of shares receivable upon exercise of this Warrant shall thereby
be proportionately increased; and, conversely, if at any time on or after the
date hereof the outstanding number of shares of Common Stock shall be combined
into a smaller number of shares, the Warrant Price in effect immediately prior
to such combination shall thereby be proportionately increased and the number of
shares receivable upon exercise of the Warrant shall be proportionately
decreased.

         (d)  ADJUSTMENTS TO WARRANT PRICE.  Whenever the number of Shares
purchasable upon exercise of this Warrant is adjusted, as herein provided, the
Warrant Price shall be adjusted by multiplying the Exercise Price in effect
immediately prior to such 


                                          4
<PAGE>


adjustment by a fraction, of which the numerator shall be the number of Shares
purchasable upon the exercise of each Warrant immediately prior to such
adjustment, and of which the denominator shall be the number of Shares so
purchasable immediately thereafter.

         (e)  CERTIFICATES AS TO ADJUSTMENTS.  Upon each adjustment of the
Warrant Price, the Company at its expense shall promptly compute such
adjustment, and furnish the Holder with a certificate of its Chief Financial
Officer setting forth such adjustment and the facts upon which such adjustment
is based.  The Company shall, upon written request, furnish the Holder a
certificate setting forth the Warrant Price in effect upon the date thereof and
the series of adjustments leading to such Warrant Price.

    6.   ACQUISITIONS.

         (a)  ASSUMPTION OF WARRANT.  If upon the closing of any Acquisition
the successor entity assumes the obligations of this Warrant, then this Warrant
shall be exercisable for the same securities, cash, and property as would be
payable for the Shares issuable upon exercise of the unexercised portion of this
Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing.
         
         (b)  NONASSUMPTION.  If upon the closing of any Acquisition the
successor entity does not assume the obligations of this Warrant and the Holder
has not otherwise exercised this Warrant in full, then the unexercised portion
of this Warrant shall be deemed to have been automatically converted pursuant to
Section 4(c) and thereafter the Holder shall participate in the acquisition on
the same terms as other holders of the same class of securities of the Company.

    7.   NOTICES; INFORMATION; REGISTRATION.

         (a)  NOTICE OF CERTAIN EVENTS.  If the Company proposes at any time
(a) to effect any reclassification or recapitalization of Common Stock; (b) to
merge or consolidate with or into any other corporation, or sell, lease,
license, or convey all or substantially all of its assets, or to liquidate,
dissolve or wind up; or (c) offer holders of registration rights the opportunity
to participate in an underwritten public offering of the company's securities
for cash, then, in connection with each such event, the Company shall give the
Holder at least 14 days prior written notice of the date on which a record will
be taken for such action.  

         (b)  INFORMATION RIGHTS.  So long as the Holder holds this Warrant
and/or any of the Shares, the Company shall deliver to the Holder (a) promptly
after mailing, copies of all notices or other written communications to the
stockholders of the Company, (b) within ninety days after the end of each fiscal
year of the Company, the annual audited financial statements of the Company
audited by independent public accountants of recognized standing and (c) within
forty-five days after the end of each of the first three quarters of each fiscal
year, the Company's quarterly, unaudited financial statements.

         (c)  REGISTRATION UNDER SECURITIES ACT OF 1933.  The Company agrees
that the Shares shall be subject to the registration rights set forth on
Exhibit B.

    8.   COMPLIANCE WITH ACT; TRANSFERABILITY AND NEGOTIABILITY OF WARRANT;
    DISPOSITION OF SHARES.

         (a)  COMPLIANCE WITH ACT.  The Holder, by acceptance hereof, agrees
that this Warrant and the Shares to be issued upon the exercise hereof are being
acquired solely for its own account and not as a nominee for any other party and
not with a view toward the resale or distribution thereof and that it will not
offer, sell or otherwise dispose of this Warrant or any Shares to be issued upon
the exercise hereof except under circumstances which will not result in a
violation of the Act.  This Warrant and the Shares to be issued upon the
exercise hereof (unless registered under the Act) shall be imprinted with a
legend in substantially the following form:

    THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
    SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED,
    ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION
    STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN
    ACCORDANCE WITH RULE 144 UNDER THE ACT, OR THE COMPANY RECEIVES AN
    OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY
    SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER,
    ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND
    PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

In addition, this Warrant and the Shares to be issued upon the exercise hereof
shall bear any legends required by the securities laws of any applicable states.

         (b)  TRANSFERABILITY AND NEGOTIABILITY OF WARRANT.  This Warrant may
not be transferred or assigned in whole or in part without compliance with all
applicable federal and state securities laws by the transferor and the
transferee (including the delivery of investment representation letters and
legal opinions satisfactory to the Company, if requested by the Company and the
transfer is to a person other than a general partner or affiliate of the initial
Holder).  Subject to the provisions of this Warrant with respect to compliance
with the Act, title to this Warrant may be transferred by endorsement and
delivery in the same manner as a negotiable instrument transferable by
endorsement and delivery.  The Company shall act promptly to record transfers of
this Warrant on its books, but the Company may treat the registered holder of
this Warrant as the absolute owner of this Warrant for all purposes,
notwithstanding any notice to the contrary.


                                          6
<PAGE>


         (c)  DISPOSITION OF SHARES.  With respect to any offer, sale, transfer
or other disposition of any Shares acquired pursuant to the exercise of this
Warrant prior to registration of such Shares, except for any such offer, sale,
transfer or other disposition of Shares to an affiliate of the initial Holder,
the Holder and each subsequent holder of this Warrant agrees to give written
notice to the Company prior thereto, describing briefly the manner thereof, and
if such transfer is not pursuant to Rule 144, a written opinion of legal counsel
for such holder, if requested by the Company, to the effect that such offer,
sale or other disposition may be effected without registration or qualification
of such Shares.  Notwithstanding the foregoing, such Shares may be offered, sold
or otherwise disposed of in accordance with Rule 144, provided that the Company
shall have been furnished with such information as the Company may reasonably
request to provide a reasonable assurance that the provisions of Rule 144 have
been satisfied.  Each certificate representing the Shares thus transferred
(except a transfer pursuant to Rule 144) shall bear a restrictive legend as to
the applicable restrictions on transferability in order to insure compliance
with the Act, unless in the aforesaid opinion of legal counsel for the holder,
such legend is not required in order to insure compliance with the Act.

    9.   RIGHTS OF STOCKHOLDERS.  No Holder shall be entitled to vote or
receive dividends or be deemed the holder of Shares or any other securities of
the Company which may at any time be issuable on the exercise of this Warrant
for any purpose, nor shall anything contained herein be construed to confer upon
the Holder, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action (whether upon any recapitalization, issuance of stock,
reclassification of stock, consolidation, merger, transfer of assets or
otherwise) or, except as expressly required herein, to receive notice of
meetings, or to receive dividends or subscription rights or otherwise until this
Warrant shall have been exercised and the Shares issuable upon exercise hereof
shall have become deliverable, as provided herein.

    10.  REPLACEMENT OF WARRANTS.  On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, on surrender and  cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

    11.  EXCHANGE OF WARRANT.  Subject to the other provisions of this Warrant,
on surrender of this Warrant for exchange, and subject to the provisions of this
Warrant with respect to compliance with the Act, the Company at its expense
shall issue to or on the order of the Holder a new warrant or warrants of like
tenor, in the name of the Holder or as the Holder (on payment by the Holder of
any applicable transfer taxes) may direct, for the number of Shares issuable
upon exercise thereof.

    12.  NOTICES.  All notices and other communications from the Company to the
Holder, or vice versa, shall be deemed delivered and effective when given
personally or 


                                          7
<PAGE>


mailed by first-class registered or certified mail, postage prepaid, at such
address as may have been furnished to the Company or the Holder, as the case may
be, in writing by the Company or such Holder from time to time.

    13.  WAIVER.  This Warrant and any term hereof may be changed, waived,
discharged or terminated only by an instrument in writing signed by the party
against which enforcement of such change, waiver, discharge or termination is
sought.

    14.  GOVERNING LAW.  This Warrant shall be governed by and construed in
accordance with the laws of the State of Delaware.

    15.  TITLES AND SUBTITLES; FORMS OF PRONOUNS.  The titles of the Sections
and Subsections of this Warrant are for convenience only and are not to be
considered in construing this Warrant.  All pronouns used in this Warrant shall
be deemed to include masculine, feminine and neuter forms.
    
    16.  ATTORNEYS' FEES.  In the event of any dispute between the parties
concerning the terms and provisions of this Warrant, the party prevailing in
such dispute shall be entitled to collect from the other party all costs
incurred in such dispute, including reasonable attorneys' fees.

Warrant and any transferee of the Warrant; and

                    (d)  The term "Warrant" means the original Warrants 
issued in connection with the Stock and Warrant Purchase Agreement, dated as 
of October 15, 1997, between the Company, as Seller, and Wexford Spectrum 
Investors LLC, a Delaware limited liability company, and Imprimis Investors 
LLC, a Delaware limited liability company, as Buyers, and all Warrants issued 
as a result of the transfer of such original Warrants.

               2.   COMPANY REGISTRATION.  If (but without any obligation to 
do so) the Company proposes at any time before October 15, 2002 to register 
(including for this purpose a registration effected by the Company for 
stockholders other than Holder) any of its stock or other securities under 
the Act in connection with the public offering for its own account of such 
securities solely for cash (other than a registration relating solely to the 
sale of securities to participants in a Company stock plan, or a registration 
on any form which does not include substantially the same information as 
would be required to be included in a registration statement covering the 
sale of the Registrable Securities), the Company shall, at such time, 
promptly give Holder written notice of such registration.  Upon the written 
request of Holder given within twenty days after mailing of such notice by 
the Company, the Company shall, subject to the provisions of Section 8 hereof 
and Section 5 of the Warrant, cause to be registered under the Act all of the 
Registrable Securities that each such Holder has requested to be registered.

               3.   DEMAND REGISTRATION.  In case the Company shall, at any 
time before October 15, 2002, receive from Holders holding 40% or more of the 
outstanding Registrable Securities a written request (to be exercised only 
once) that the Company effect a registration and any related qualification or 
compliance with respect to all or a part of the Registrable Securities (which 
registration shall at the election of Holder either be for a registration for 
a primary issuance of the Shares upon the exercise of the Warrant or the 
resale of the Shares previously issued upon exercise of the Warrant at the 
election of Holder) owned by such Holder, the Company will promptly notify 
each other Holder (if any) of such request and will:


<PAGE>


                    (a)  as soon as practicable, effect such registration and 
all such qualifications and compliances as may be so requested and as would 
permit or facilitate the sale and distribution of all or such portion of a 
Holder's Registrable Securities as are specified in such request, together 
with all or such portion of the Registrable Securities of any other holder of 
registration rights joining in such request as are specified in a written 
request given within 20 days after receipt of such written notice from the 
Company; PROVIDED, HOWEVER, that the Company shall not be obligated to effect 
any such registration, qualification or compliance, pursuant to this Section 
3:  (1) if the Company has effected a registration of Registrable Securities 
pursuant to this Section 3 within the preceding 12 months; (2) if the Company 
shall furnish to Holder a certificate signed by the President of the Company 
stating that in the good faith judgment of the Board of Directors of the 
Company, it would be seriously detrimental to the Company and its 
stockholders for such registration to be effected at such time, in which 
event the Company shall have the right to defer the filing of the 
registration statement for a period of not more than 60 days after receipt of 
the request of Holder under this Section 3; PROVIDED, HOWEVER, that the 
Company shall not utilize this right more than once in any twelve-month 
period; or (3) in any jurisdiction in which the Company would be required to 
qualify to do business or to execute a general consent to service of process 
in effecting such registration, qualification or compliance; and,

                    (b)  subject to the foregoing, file a registration 
statement covering the Registrable Securities and other securities so 
requested to be registered promptly after receipt of the request or requests 
of Holder, and in any event within 30 days of receipt of such request.

               4.   OBLIGATION OF THE COMPANY.  Subject to the terms of the 
Warrant, in the event that the Company is to effect the registration of any 
Registrable Securities pursuant to Section 2 or 3 hereof, the Company shall 
promptly:

                    (a)  Prepare and file with the SEC a registration 
statement with respect to such Registrable Securities and use its best 
efforts to cause such registration statement to become effective, and, upon 
the request of the holders of a majority of the securities registered 
thereunder, keep such registration statement effective for up to one hundred 
twenty (120) days, or such shorter period as is required to dispose of all 
securities covered by such registration statement.

                    (b)  Prepare and file with the SEC such amendments and 
supplements to such registration statement and the prospectus used in 
connection with such registration statement as may be necessary to comply 
with the provisions of the Act with respect to the disposition of all 
securities covered by such registration statement.

                    (c)  Furnish to Holder such number of copies of a 
prospectus, including a preliminary prospectus, in conformity with the 
requirements of the Act, and such other documents as Holder may reasonably 
request in order to facilitate the disposition of Registrable Securities 
owned by Holder.

                    (d)  Use its best efforts to register and qualify the 
securities covered by such registration statement under such other securities 
or Blue Sky laws of such jurisdictions as shall be reasonably requested by 
Holder, provided that the Company shall not be required in connection 
therewith or as a condition thereto to qualify to do business or to file a 
general consent to service of process in any such states or jurisdictions or 
to agree to any restrictions as to the conduct of its business in the 
ordinary course thereof.

                    (e)  In the event of any underwritten public offering, 
enter into and perform its obligations under an underwriting agreement, in 
usual and customary form, with the managing underwriter of such offering.  
Holder shall also enter into and perform its obligations under such 
underwriting agreement.


                                          2
<PAGE>


                    (f)  Notify Holder at any time when a prospectus relating 
to Registrable Securities of Holder covered by such registration statement is 
required to be delivered under the Act, of the happening of any event as a 
result of which the prospectus included in such registration statement, as 
then in effect, includes an untrue statement of a material fact or omits to 
state a material fact required to be stated therein or necessary to make the 
statements therein not misleading in the light of the circumstances under 
which they were made.

                    (g)  Furnish, at the request of Holder, on the date that 
such Registrable Securities are delivered to the underwriters for sale in 
connection with a registration pursuant to the Warrant, if such securities 
are being sold through underwriters, or, if such securities are not being 
sold through underwriters, on the date that the registration statement with 
respect to such securities becomes effective, (i) an opinion, dated such 
date, of counsel representing the Company for the purposes of such 
registration, in form and substance as is customarily given to underwriters 
in an underwritten public offering, addressed to the underwriters, if any, 
and to Holder and (ii) a letter dated such date, from the independent 
certified public accountants of the Company, in form and substance as is 
customarily given by independent certified public accountants to underwriters 
in an underwritten public offering, addressed to the underwriters, if any, 
and to Holder.

               5.   AVAILABILITY OF RULE 144.  Notwithstanding anything in 
the Warrant or this Statement of Registration Rights to the contrary, the 
Company shall not be obligated to effect any such registration, qualification 
or compliance, pursuant to Section 2 or 3, if application of Rule 144 would 
allow Holder requesting a registration under Section 2 or 3 to dispose of the 
Registrable Securities for which a registration is demanded within a single 
90-day period.

               6.   FURNISH INFORMATION.  It shall be a condition precedent 
to the obligations of the Company to take any action pursuant to the Warrant 
that the selling Holder shall furnish to the Company such information 
regarding itself, the Registrable Securities held by Holder, and the intended 
method of disposition of such securities as shall be required to effect the 
registration of their Registrable Securities.

               7.   EXPENSES.  The Company shall bear and pay all expenses 
(other than underwriting discounts and commissions) incurred in connection 
with any registration, filing or qualification of Registrable Securities, 
including (without limitation) all registration, filing, and qualification 
fees, legal, printers and accounting fees relating thereto, and the cost of 
any reasonable fees or disbursements of counsel for Holder.

               8.   UNDERWRITING REQUIREMENTS.  In connection with any 
registrations in which Registrable Securities have a right to be included 
pursuant to Section 2 hereof and which involves an underwriting of securities 
being issued by the Company, the Company shall not be required, under Section 
2 hereof, to include any of Holder's securities in such underwriting unless 
Holder accepts the terms of the underwriting as agreed upon between the 
Company and the underwriters selected by it, and then only in such quantity 
as will not, in the opinion of the underwriters, jeopardize the success of 
the offering by the Company.  If the total amount of securities, including 
Registrable Securities, requested by stockholders to be included in such 
offering exceeds the amount of securities sold other than by the Company that 
the underwriters reasonably believe compatible with the success of the 
offering, then the Company shall be required to include in the offering only 
that number of such securities, including Registrable Securities, which the 
underwriters believe will not jeopardize the success of the offering, the 
securities so included to be apportioned pro rata among the selling Holder 
and other shareholders holding contractual registration rights according to 
the total amount of securities entitled to be included herein owned by each 
selling stockholder or in such other proportions as shall mutually be agreed 
to by Holder and each other selling stockholder.

               9.   INDEMNIFICATION.  In the event any Registrable Securities 
are included n a registration statement filed by the Company:

                    (a)  The Company will indemnify and holder harmless 
Holder, its officers, directors, and agents, any underwriter (as defined in 
the Act) for Holder and each person, if any, who controls Holder or 
underwriter within the meaning of the Act or the Securities Exchange Act of 
1934, as amended (the "1934 Act"), against any losses, claims, damages, or 
liabilities (joint or several) asserted by a third party to which they may 
become subject under the Act, the 1934 Act or other federal or state law, 
insofar as such losses, claims, damages, or liabilities (or actions in 
respect thereof) arise out of or are based upon any of the following 
statements, omissions or violations (collectively a "Violation"):  (i) any 
untrue statement or alleged untrue statement of a material fact contained in 
such registration statement, including any preliminary prospectus or final 
prospectus contained therein or any amendments or supplements thereto, (ii) 
the omission or alleged omission to state therein a material fact required to 
be stated therein, or necessary to make the statements therein not 
misleading, or (iii) any violation or alleged violation of the Company of the 
Act, the 1934 Act, any state securities law or any rule or regulation 
promulgated under the Act, the 1934 Act or any state securities law; and the 
Company will reimburse Holder, any of its officers or directors, underwriter 
or controlling person for any legal or other expenses reasonably incurred by 
them, as incurred, in connection with investigating or defending any such 
loss, claim, damage, liability, or action; PROVIDED, HOWEVER, that the 
indemnity agreement contained in this Section 9(a) shall not apply to amounts 
paid in settlement of any such loss, claim, damage, liability or action if 
such settlement is effected without the consent of the Company (which consent 
shall not be unreasonably withheld), nor shall the Company be liable in any 
such case for any such loss, claim, damage, liability, or action to the 
extent that it arises out of or is based upon a Violation which occurs in 
reliance upon and in conformity with written information furnished expressly 
for use in connection with such registration by such Holder, underwriter or 
controlling person.

                    (b)  Holder will indemnify and hold harmless the Company, 
each of its directors, each of its officers who have signed the registration 
statement, each person, if any, who controls the Company with the meaning of 
the Act, any underwriter and any other shareholder selling securities in such 
registration statement or any of its directors or officers or any person who 
controls such shareholder, against any losses, claims, damages, or 
liabilities (joint or several) asserted by a third party to which the Company 
or any such director, officer, controlling person, or underwriter or 
controlling person, or other such shareholder or director, officer or 
controlling person may become subject, under the Act, the 1934 Act or other 
federal or state law, insofar as such losses, claims, damages, or liabilities 
(or actions in respect thereto) arise out of or are based upon any Violation, 
in each case to the extent (and only to the extent) that such Violation 
occurs in reliance upon and in conformity with written information furnished 
by Holder expressly for use in connection with such registration; and Holder 
will reimburse any legal or other expenses reasonably incurred by the Company 
or any such director, officer, controlling person, underwriter or controlling 
person, other shareholder, officer, director, or controlling person, as 
incurred, in connection with investigating or defending any such loss, claim, 
damage, liability, or action; PROVIDED, HOWEVER, that the obligations of 
Holder hereunder shall be limited to an amount equal to the net proceeds 
(equal to the offering price less the exercise price, expenses and 
underwriting commissions and discounts) to such Holder of Shares sold as 
contemplated herein.  Notwithstanding the foregoing, the indemnity agreement 
contained in this Section 9(b) shall not apply to amounts paid in settlement 
of any such loss, claim, damage, liability or action if such settlement is 
effected without the consent of Holder, which consent shall not be 
unreasonably withheld.

                    (c)  Promptly after receipt by an indemnified party under 
this Section 9 of notice of the commencement of any action (including any 
governmental action), such indemnified party will, if a claim in respect 
thereof is to be made against any indemnifying part under this Section 9, 
deliver to the indemnifying party a written notice of the commencement 
thereof and the indemnifying party shall have the right to participate in, 
and, to the extent the indemnifying party so desires, jointly with any other 
indemnifying party 


                                          4
<PAGE>


similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; PROVIDED, HOWEVER, that an indemnified party shall
have the right to  retain its own counsel, with the fees and expenses to be paid
by the  indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceeding.  The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to  defend such
action, shall relieve such indemnifying party of any liability to  the
indemnified party under this Section 9, but the omission so to deliver  written
notice to the indemnifying party will not relieve it of any liability  that it
may have to any indemnified party otherwise than under this Section 9.

               10.  REPORTS UNDER THE 1934 ACT.  With a view to making 
available to Holder the benefits of Rule 144 promulgated under the Act and 
any other rule or regulation of the SEC that may at any time permit Holder to 
sell securities of the Company to the public without registration the Company 
will endeavor to:

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

                    (b)  take such action as is necessary to enable Holder to 
utilize an abbreviated registration statement for the sale of its Registrable 
Securities;

                    (c)  file with the SEC in a timely manner all reports and 
other documents required of the Company under the Act and the 1934 Act; and

                    (d)  furnish to Holder, so long as Holder owns any 
Registrable Securities, forthwith upon request (i) a written statement by the 
Company that it has complied with the reporting requirements of SEC Rule 144, 
the Act and the 1934 Act, or that it qualifies as a registrant whose 
securities may be resold pursuant to Form S-3 (at any time after it so 
qualifies), (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 in availing 
Holder of any rule or regulation of the SEC which permits the selling of any 
such securities without registration or pursuant to such form.

               11.  ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause 
the Company to register Registrable Securities pursuant to the Warrant may be 
assigned by Holder to a permitted transferee or assignee of the Warrant of 
all 150,000 Shares, provided the Company is, within a reasonable time after 
such transfer, furnished with written notice of the name and address of such 
transferee or assignee and the securities with respect to which such 
registration rights are being assigned; and provided, further, that such 
assignment shall be effective only if immediately following such transfer the 
further disposition of such securities by the transferee or assignee is 
restricted under the Act.

its Annual Meeting of Stockholders for, among other things, a proposal to 
amend its Certificate of Incorporation to increase the number of shares of 
Common Stock authorized for issuance.  If such proposal is approved by the 
Company's stockholders, the Company shall file a Certificate of Amendment to 
its Certificate of Incorporation with the Secretary of State of the State of 
Delaware (the "Amendment") in order to increase such number of authorized 
shares of Common Stock.  From and after the date of filing the Amendment, all 
Shares which may be issued upon the exercise of the purchase right

issued, fully paid and non-assessable, and free of any liens and encumbrances 
except for restrictions on transfer under applicable federal and state 
securities laws.  From and after the date of the Amendment, during the period 
within which the purchase right represented by this Warrant may be exercised,

exercise of this Warrant in accordance with the terms hereof will not be, 
inconsistent with the Company's Certificate of Incorporation or Bylaws, do 
not and will not contravene any law, governmental rule or regulation, 
judgment or order applicable to the Company, and do not and will not conflict 
with or contravene any provision of, or constitute a default under, any 
material indenture, mortgage, contract or other instrument of which the 
Company is a party or by which it is bound, or require the registration or 
filing with or the taking of any action in respect of or by, any federal, 
state or local government authority or agency (other than such consents, 
approvals, notices, actions, or filings as have already been obtained or 
made, as the case may be).

    5.   ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES.  The number of 
Shares issuable upon the exercise of this Warrant and the Warrant Price shall 
be subject to adjustment from time to time upon the occurrence of certain 
events, as follows:

         (a)  ADJUSTMENT FOR DIVIDENDS IN STOCK.  In case at any time or from 
time to time on or after the date hereof the holders of the Common Stock of 
the Company (or any shares of stock or other securities at the time 
receivable upon the exercise of this Warrant) shall have received or, on or 
after the record date fixed for the determination of eligible stockholders, 
shall have become entitled to receive, without payment therefor, other or 
additional stock of the Company by way of dividend then, and in each case, 
the Holder of this Warrant shall, upon the exercise hereof, be entitled to 
receive, in addition to the number of shares of Common Stock receivable 
thereupon, and without payment of any additional  consideration therefor, the 
amount of such other or additional stock of the Company which such Holder 
would hold on the date of such exercise had it been the holder of record of 
such Common Stock on the date hereof and had thereafter, during the period 
from the date hereof to and including the date of such exercise, retained 
such shares and/or all other additional stock receivable by it as aforesaid 
during such period, giving effect to all adjustments called for during such 
period by paragraphs (b) and (c) of this Section 5.
         
         (b)  ADJUSTMENT FOR RECLASSIFICATION OR REORGANIZATION.  In case of 
any reclassification or change of the outstanding securities of the Company 
or of any consolidation, merger or reorganization of the Company on or after 
the date hereof, then and in each such case the Holder of this Warrant, upon 
the exercise hereof at any time after the consummation of such 
reclassification, change, consolidation, merger or reorganization, shall be 
entitled to receive, in lieu of or in addition to the stock or other 
securities and property receivable upon the exercise hereof prior to such 
consummation, the stock or other securities to which such Holder would have 
been entitled upon such consummation if such Holder had exercised this 
Warrant immediately prior thereto, all subject to further adjustment as 
provided in subparagraphs (a) and (c); in each such case, the terms of this 
Paragraph 5 shall be applicable to the shares of stock or other securities 
property receivable upon the exercise of this Warrant after such consummation.
         
         (c)  STOCK SPLITS AND REVERSE STOCK SPLITS.  If, at any time on or 
after the date hereof, the Company shall subdivide its outstanding shares of 
Common Stock into a greater number of shares, the Warrant Price in effect 
immediately prior to such subdivision shall thereby be proportionately 
reduced and the number of shares receivable upon exercise of this Warrant 
shall thereby be proportionately increased; and, conversely, if at any time 
on or after the date hereof the outstanding number of shares of Common Stock 
shall be combined into a smaller number of shares, the Warrant Price in 
effect immediately prior to such combination shall thereby be proportionately 
increased and the number of shares receivable upon exercise of the Warrant 
shall be proportionately decreased.
         
         (d)  ADJUSTMENTS TO WARRANT PRICE.  Whenever the number of Shares 
purchasable upon exercise of this Warrant is adjusted, as herein provided, 
the Warrant Price shall be adjusted by multiplying the Exercise Price in 
effect immediately prior to such 

                                          4
<PAGE>

adjustment by a fraction, of which the numerator shall be the number of 
Shares purchasable upon the exercise of each Warrant immediately prior to 
such adjustment, and of which the denominator shall be the number of Shares 
so purchasable immediately thereafter.
         
         (e)  CERTIFICATES AS TO ADJUSTMENTS.  Upon each adjustment of the 
Warrant Price, the Company at its expense shall promptly compute such 
adjustment, and furnish the Holder with a certificate of its Chief Financial 
Officer setting forth such adjustment and the facts upon which such 
adjustment is based.  The Company shall, upon written request, furnish the 
Holder a certificate setting forth the Warrant Price in effect upon the date 
thereof and the series of adjustments leading to such Warrant Price.

    6.   ACQUISITIONS.

         (a)  ASSUMPTION OF WARRANT.  If upon the closing of any Acquisition 
the successor entity assumes the obligations of this Warrant, then this 
Warrant shall be exercisable for the same securities, cash, and property as 
would be payable for the Shares issuable upon exercise of the unexercised 
portion of this Warrant as if such Shares were outstanding on the record date 
for the Acquisition and subsequent closing.
         
         (b)  NONASSUMPTION.  If upon the closing of any Acquisition the 
successor entity does not assume the obligations of this Warrant and the 
Holder has not otherwise exercised this Warrant in full, then the unexercised 
portion of this Warrant shall be deemed to have been automatically converted 
pursuant to Section 4(c) and thereafter the Holder shall participate in the 
acquisition on the same terms as other holders of the same class of 
securities of the Company.

    7.   NOTICES; INFORMATION; REGISTRATION.

         (a)  NOTICE OF CERTAIN EVENTS.  If the Company proposes at any time 
(a) to effect any reclassification or recapitalization of Common Stock; (b) 
to merge or consolidate with or into any other corporation, or sell, lease, 
license, or convey all or substantially all of its assets, or to liquidate, 
dissolve or wind up; or (c) offer holders of registration rights the 
opportunity to participate in an underwritten public offering of the 
company's securities for cash, then, in connection with each such event, the 
Company shall give the Holder at least 14 days prior written notice of the 
date on which a record will be taken for such action.  
         
         (b)  INFORMATION RIGHTS.  So long as the Holder holds this Warrant 
and/or any of the Shares, the Company shall deliver to the Holder (a) 
promptly after mailing, copies of all notices or other written communications 
to the stockholders of the Company, (b) within ninety days after the end of 
each fiscal year of the Company, the annual audited financial statements of 
the Company audited by independent public accountants of recognized standing 
and (c) within forty-five days after the end of each of the first three 
quarters of each fiscal year, the Company's quarterly, unaudited financial 
statements.

         (c)  REGISTRATION UNDER SECURITIES ACT OF 1933.  The Company agrees 
that the Shares shall be subject to the registration rights set forth on 
Exhibit B.

    8.   COMPLIANCE WITH ACT; TRANSFERABILITY AND NEGOTIABILITY OF WARRANT;
          DISPOSITION OF SHARES.

         (a)  COMPLIANCE WITH ACT.  The Holder, by acceptance hereof, agrees 
that this Warrant and the Shares to be issued upon the exercise hereof are 
being acquired solely for its own account and not as a nominee for any other 
party and not with a view toward the resale or distribution thereof and that 
it will not offer, sell or otherwise dispose of this Warrant or any Shares to 
be issued upon the exercise hereof except under circumstances which will not 
result in a violation of the Act.  This Warrant and the Shares to be issued 
upon the exercise hereof (unless registered under the Act) shall be imprinted 
with a legend in substantially the following form:
         
    THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
    SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED,
    ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION
    STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN
    ACCORDANCE WITH RULE 144 UNDER THE ACT, OR THE COMPANY RECEIVES AN
    OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY
    SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER,
    ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND
    PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

In addition, this Warrant and the Shares to be issued upon the exercise 
hereof shall bear any legends required by the securities laws of any 
applicable states.

         (b)  TRANSFERABILITY AND NEGOTIABILITY OF WARRANT.  This Warrant may 
not be transferred or assigned in whole or in part without compliance with 
all applicable federal and state securities laws by the transferor and the 
transferee (including the delivery of investment representation letters and 
legal opinions satisfactory to the Company, if requested by the Company and 
the transfer is to a person other than a general partner or affiliate of the 
initial Holder).  Subject to the provisions of this Warrant with respect to 
compliance with the Act, title to this Warrant may be transferred by 
endorsement and delivery in the same manner as a negotiable instrument 
transferable by endorsement and delivery.  The Company shall act promptly to 
record transfers of this Warrant on its books, but the Company may treat the 
registered holder of this Warrant as the absolute owner of this Warrant for 
all purposes, notwithstanding any notice to the contrary.

                                          6
<PAGE>

         (c)  DISPOSITION OF SHARES.  With respect to any offer, sale, 
transfer or other disposition of any Shares acquired pursuant to the exercise 
of this Warrant prior to registration of such Shares, except for any such 
offer, sale, transfer or other disposition of Shares to an affiliate of the 
initial Holder, the Holder and each subsequent holder of this Warrant agrees 
to give written notice to the Company prior thereto, describing briefly the 
manner thereof, and if such transfer is not pursuant to Rule 144, a written 
opinion of legal counsel for such holder, if requested by the Company, to the 
effect that such offer, sale or other disposition may be effected without 
registration or qualification of such Shares.  Notwithstanding the foregoing, 
such Shares may be offered, sold or otherwise disposed of in accordance with 
Rule 144, provided that the Company shall have been furnished with such 
information as the Company may reasonably request to provide a reasonable 
assurance that the provisions of Rule 144 have been satisfied.  Each 
certificate representing the Shares thus transferred (except a transfer 
pursuant to Rule 144) shall bear a restrictive legend as to the applicable 
restrictions on transferability in order to insure compliance with the Act, 
unless in the aforesaid opinion of legal counsel for the holder, such legend 
is not required in order to insure compliance with the Act.

    9.   RIGHTS OF STOCKHOLDERS.  No Holder shall be entitled to vote or 
receive dividends or be deemed the holder of Shares or any other securities 
of the Company which may at any time be issuable on the exercise of this 
Warrant for any purpose, nor shall anything contained herein be construed to 
confer upon the Holder, as such, any of the rights of a stockholder of the 
Company or any right to vote for the election of directors or upon any matter 
submitted to stockholders at any meeting thereof, or to give or withhold 
consent to any corporate action (whether upon any recapitalization, issuance 
of stock, reclassification of stock, consolidation, merger, transfer of 
assets or otherwise) or, except as expressly required herein, to receive 
notice of meetings, or to receive dividends or subscription rights or 
otherwise until this Warrant shall have been exercised and the Shares 
issuable upon exercise hereof shall have become deliverable, as provided 
herein.

    10.  REPLACEMENT OF WARRANTS.  On receipt of evidence reasonably 
satisfactory to the Company of the loss, theft, destruction or mutilation of 
this Warrant and, in the case of loss, theft or destruction, on delivery of 
an indemnity agreement reasonably satisfactory in form and amount to the 
Company or, in the case of mutilation, on surrender and  cancellation of this 
Warrant, the Company at its expense shall execute and deliver, in lieu of 
this Warrant, a new warrant of like tenor.

    11.  EXCHANGE OF WARRANT.  Subject to the other provisions of this 
Warrant, on surrender of this Warrant for exchange, and subject to the 
provisions of this Warrant with respect to compliance with the Act, the 
Company at its expense shall issue to or on the order of the Holder a new 
warrant or warrants of like tenor, in the name of the Holder or as the Holder 
(on payment by the Holder of any applicable transfer taxes) may direct, for 
the number of Shares issuable upon exercise thereof.

    12.  NOTICES.  All notices and other communications from the Company to 
the Holder, or vice versa, shall be deemed delivered and effective when given 
personally or 

                                          7
<PAGE>


mailed by first-class registered or certified mail, postage prepaid, at such 
address as may have been furnished to the Company or the Holder, as the case 
may be, in writing by the Company or such Holder from time to time.

    13.  WAIVER.  This Warrant and any term hereof may be changed, waived, 
discharged or terminated only by an instrument in writing signed by the party 
against which enforcement of such change, waiver, discharge or termination is 
sought.

    14.  GOVERNING LAW.  This Warrant shall be governed by and construed in 
accordance with the laws of the State of Delaware.

    15.  TITLES AND SUBTITLES; FORMS OF PRONOUNS.  The titles of the Sections 
and Subsections of this Warrant are for convenience only and are not to be 
considered in construing this Warrant.  All pronouns used in this Warrant 
shall be deemed to include masculine, feminine and neuter forms.
    
    16.  ATTORNEYS' FEES.  In the event of any dispute between the parties 
concerning the terms and provisions of this Warrant, the party prevailing in 
such dispute shall be entitled to collect from the other party all costs 
incurred in such dispute, including reasonable attorneys' fees.

                                      EXHIBIT B
                                           

                           STATEMENT OF REGISTRATION RIGHTS
                                           


         1.   DEFINITIONS.  For purposes of the Warrant to which this 
Statement of Registration Rights is attached as Exhibit B:

              (a)  The terms "register," "registered," and "registration" 
refer to a registration effected by preparing and filing a registration 
statement or similar document in compliance with the Securities Act of 1933, 
as amended (the "Act"), and the declaration or ordering of effectiveness of 
such registration statement or document;
                    
              (b)  The term "Registrable Securities" means the shares of 
Common Stock issued or issuable upon exercise of the Warrant;
                    
              (c)  The term "Holder" means the original holder of the Warrant 
and any transferee of the Warrant; and
                    
               (d)  The term "Warrant" means the original Warrants issued in 
connection with the Stock and Warrant Purchase Agreement, dated as of October 
15, 1997, between the Company, as Seller, and Wexford Spectrum Investors LLC, 
a Delaware limited liability company, and Imprimis Investors LLC, a Delaware 
limited liability company, as Buyers, and all Warrants issued as a result of 
the transfer of such original Warrants.

         2.   COMPANY REGISTRATION.  If (but without any obligation to do so) 
the Company proposes at any time before October 15, 2002 to register 
(including for this purpose a registration effected by the Company for 
stockholders other than Holder) any of its stock or other securities under 
the Act in connection with the public offering for its own account of such 
securities solely for cash (other than a registration relating solely to the 
sale of securities to participants in a Company stock plan, or a registration 
on any form which does not include substantially the same information as 
would be required to be included in a registration statement covering the 
sale of the Registrable Securities), the Company shall, at such time, 
promptly give Holder written notice of such registration.  Upon the written 
request of Holder given within twenty days after mailing of such notice by 
the Company, the Company shall, subject to the provisions of Section 8 hereof 
and Section 5 of the Warrant, cause to be registered under the Act all of the 
Registrable Securities that each such Holder has requested to be registered.

         3.   DEMAND REGISTRATION.  In case the Company shall, at any time 
before October 15, 2002, receive from Holders holding 40% or more of the 
outstanding Registrable Securities a written request (to be exercised only 
once) that the Company effect a registration and any related qualification or 
compliance with respect to all or a part of the Registrable Securities (which 
registration shall at the election of Holder either be for a registration for 
a primary issuance of the Shares upon the exercise of the Warrant or the 
resale of the Shares previously issued upon exercise of the Warrant at the 
election of Holder) owned by such Holder, the Company will promptly notify 
each other Holder (if any) of such request and will:

<PAGE>


              (a)  as soon as practicable, effect such registration and all 
such qualifications and compliances as may be so requested and as would 
permit or facilitate the sale and distribution of all or such portion of a 
Holder's Registrable Securities as are specified in such request, together 
with all or such portion of the Registrable Securities of any other holder of 
registration rights joining in such request as are specified in a written 
request given within 20 days after receipt of such written notice from the 
Company; PROVIDED, HOWEVER, that the Company shall not be obligated to effect 
any such registration, qualification or compliance, pursuant to this Section 
3: (1) if the Company has effected a registration of Registrable Securities 
pursuant to this Section 3 within the preceding 12 months; (2) if the Company 
shall furnish to Holder a certificate signed by the President of the Company 
stating that in the good faith judgment of the Board of Directors of the 
Company, it would be seriously detrimental to the Company and its 
stockholders for such registration to be effected at such time, in which 
event the Company shall have the right to defer the filing of the 
registration statement for a period of not more than 60 days after receipt of 
the request of Holder under this Section 3; PROVIDED, HOWEVER, that the 
Company shall not utilize this right more than once in any twelve-month 
period; or (3) in any jurisdiction in which the Company would be required to 
qualify to do business or to execute a general consent to service of process 
in effecting such registration, qualification or compliance; and,
                    
              (b)  subject to the foregoing, file a registration statement 
covering the Registrable Securities and other securities so requested to be 
registered promptly after receipt of the request or requests of Holder, and 
in any event within 30 days of receipt of such request.
                    
         4.   OBLIGATION OF THE COMPANY.  Subject to the terms of the 
Warrant, in the event that the Company is to effect the registration of any 
Registrable Securities pursuant to Section 2 or 3 hereof, the Company shall 
promptly:

              (a)  Prepare and file with the SEC a registration statement 
with respect to such Registrable Securities and use its best efforts to cause 
such registration statement to become effective, and, upon the request of the 
holders of a majority of the securities registered thereunder, keep such 
registration statement effective for up to one hundred twenty (120) days, or 
such shorter period as is required to dispose of all securities covered by 
such registration statement.

              (b)  Prepare and file with the SEC such amendments and 
supplements to such registration statement and the prospectus used in 
connection with such registration statement as may be necessary to comply 
with the provisions of the Act with respect to the disposition of all 
securities covered by such registration statement.

              (c)  Furnish to Holder such number of copies of a prospectus, 
including a preliminary prospectus, in conformity with the requirements of 
the Act, and such other documents as Holder may reasonably request in order 
to facilitate the disposition of Registrable Securities owned by Holder.
                    
              (d)  Use its best efforts to register and qualify the 
securities covered by such registration statement under such other securities 
or Blue Sky laws of such jurisdictions as shall be reasonably requested by 
Holder, provided that the Company shall not be required in connection 
therewith or as a condition thereto to qualify to do business or to file a 
general consent to service of process in any such states or jurisdictions or 
to agree to any restrictions as to the conduct of its business in the 
ordinary course thereof.
                    
              (e)  In the event of any underwritten public offering, enter 
into and perform its obligations under an underwriting agreement, in usual 
and customary form, with the managing underwriter of such offering.  Holder 
shall also enter into and perform its obligations under such underwriting 
agreement.

                                          2

<PAGE>
                    
              (f)  Notify Holder at any time when a prospectus relating to 
Registrable Securities of Holder covered by such registration statement is 
required to be delivered under the Act, of the happening of any event as a 
result of which the prospectus included in such registration statement, as 
then in effect, includes an untrue statement of a material fact or omits to 
state a material fact required to be stated therein or necessary to make the 
statements therein not misleading in the light of the circumstances under 
which they were made.
                    
              (g)  Furnish, at the request of Holder, on the date that such 
Registrable Securities are delivered to the underwriters for sale in 
connection with a registration pursuant to the Warrant, if such securities 
are being sold through underwriters, or, if such securities are not being 
sold through underwriters, on the date that the registration statement with 
respect to such securities becomes effective, (i) an opinion, dated such 
date, of counsel representing the Company for the purposes of such 
registration, in form and substance as is customarily given to underwriters 
in an underwritten public offering, addressed to the underwriters, if any, 
and to Holder and (ii) a letter dated such date, from the independent 
certified public accountants of the Company, in form and substance as is 
customarily given by independent certified public accountants to underwriters 
in an underwritten public offering, addressed to the underwriters, if any, 
and to Holder.

         5.   AVAILABILITY OF RULE 144.  Notwithstanding anything in the 
Warrant or this Statement of Registration Rights to the contrary, the Company 
shall not be obligated to effect any such registration, qualification or 
compliance, pursuant to Section 2 or 3, if application of Rule 144 would 
allow Holder requesting a registration under Section 2 or 3 to dispose of the 
Registrable Securities for which a registration is demanded within a single 
90-day period.

         6.   FURNISH INFORMATION.  It shall be a condition precedent to the 
obligations of the Company to take any action pursuant to the Warrant that 
the selling Holder shall furnish to the Company such information regarding 
itself, the Registrable Securities held by Holder, and the intended method of 
disposition of such securities as shall be required to effect the 
registration of their Registrable Securities.

         7.   EXPENSES.  The Company shall bear and pay all expenses (other 
than underwriting discounts and commissions) incurred in connection with any 
registration, filing or qualification of Registrable Securities, including 
(without limitation) all registration, filing, and qualification fees, legal, 
printers and accounting fees relating thereto, and the cost of any reasonable 
fees or disbursements of counsel for Holder.

         8.   UNDERWRITING REQUIREMENTS.  In connection with any 
registrations in which Registrable Securities have a right to be included 
pursuant to Section 2 hereof and which involves an underwriting of securities 
being issued by the Company, the Company shall not be required, under Section 
2 hereof, to include any of Holder's securities in such underwriting unless 
Holder accepts the terms of the underwriting as agreed upon between the 
Company and the underwriters selected by it, and then only in such quantity 
as will not, in the opinion of the underwriters, jeopardize the success of 
the offering by the Company.  If the total amount of securities, including 
Registrable Securities, requested by stockholders to be included in such 
offering exceeds the amount of securities sold other than by the Company that 
the underwriters reasonably believe compatible with the success of the 
offering, then the Company shall be required to include in the offering only 
that number of such securities, including Registrable Securities, which the 
underwriters believe will not jeopardize the success of the offering, the 
securities so included to be apportioned pro rata among the selling Holder 
and other shareholders holding contractual registration rights according to 
the total amount of securities entitled to be included herein owned by each 
selling stockholder or in such other proportions as shall mutually be agreed 
to by Holder and each other selling stockholder.

                                          3

         9.   INDEMNIFICATION.  In the event any Registrable Securities are 
included n a registration statement filed by the Company:

              (a)  The Company will indemnify and holder harmless Holder, its 
officers, directors, and agents, any underwriter (as defined in the Act) for 
Holder and each person, if any, who controls Holder or underwriter within the 
meaning of the Act or the Securities Exchange Act of 1934, as amended (the 
"1934 Act"), against any losses, claims, damages, or liabilities (joint or 
several) asserted by a third party to which they may become subject under the 
Act, the 1934 Act or other federal or state law, insofar as such losses, 
claims, damages, or liabilities (or actions in respect thereof) arise out of 
or are based upon any of the following statements, omissions or violations 
(collectively a "Violation"):  (i) any untrue statement or alleged untrue 
statement of a material fact contained in such registration statement, 
including any preliminary prospectus or final prospectus contained therein or 
any amendments or supplements thereto, (ii) the omission or alleged omission 
to state therein a material fact required to be stated therein, or necessary 
to make the statements therein not misleading, or (iii) any violation or 
alleged violation of the Company of the Act, the 1934 Act, any state 
securities law or any rule or regulation promulgated under the Act, the 1934 
Act or any state securities law; and the Company will reimburse Holder, any 
of its officers or directors, underwriter or controlling person for any legal 
or other expenses reasonably incurred by them, as incurred, in connection 
with investigating or defending any such loss, claim, damage, liability, or 
action; PROVIDED, HOWEVER, that the indemnity agreement contained in this 
Section 9(a) shall not apply to amounts paid in settlement of any such loss, 
claim, damage, liability or action if such settlement is effected without the 
consent of the Company (which consent shall not be unreasonably withheld), 
nor shall the Company be liable in any such case for any such loss, claim, 
damage, liability, or action to the extent that it arises out of or is based 
upon a Violation which occurs in reliance upon and in conformity with written 
information furnished expressly for use in connection with such registration 
by such Holder, underwriter or controlling person.
                    
              (b)  Holder will indemnify and hold harmless the Company, each 
of its directors, each of its officers who have signed the registration 
statement, each person, if any, who controls the Company with the meaning of 
the Act, any underwriter and any other shareholder selling securities in such 
registration statement or any of its directors or officers or any person who 
controls such shareholder, against any losses, claims, damages, or 
liabilities (joint or several) asserted by a third party to which the Company 
or any such director, officer, controlling person, or underwriter or 
controlling person, or other such shareholder or director, officer or 
controlling person may become subject, under the Act, the 1934 Act or other 
federal or state law, insofar as such losses, claims, damages, or liabilities 
(or actions in respect thereto) arise out of or are based upon any Violation, 
in each case to the extent (and only to the extent) that such Violation 
occurs in reliance upon and in conformity with written information furnished 
by Holder expressly for use in connection with such registration; and Holder 
will reimburse any legal or other expenses reasonably incurred by the Company 
or any such director, officer, controlling person, underwriter or controlling 
person, other shareholder, officer, director, or controlling person, as 
incurred, in connection with investigating or defending any such loss, claim, 
damage, liability, or action; PROVIDED, HOWEVER, that the obligations of 
Holder hereunder shall be limited to an amount equal to the net proceeds 
(equal to the offering price less the exercise price, expenses and 
underwriting commissions and discounts) to such Holder of Shares sold as 
contemplated herein.  Notwithstanding the foregoing, the indemnity agreement 
contained in this Section 9(b) shall not apply to amounts paid in settlement 
of any such loss, claim, damage, liability or action if such settlement is 
effected without the consent of Holder, which consent shall not be 
unreasonably withheld.
                    
              (c)  Promptly after receipt by an indemnified party under this 
Section 9 of notice of the commencement of any action (including any 
governmental action), such indemnified party will, if a claim in respect 
thereof is to be made against any indemnifying part under this Section 9, 
deliver to the indemnifying party a written notice of the commencement 
thereof and the indemnifying party shall have the right to participate in, 
and, to the extent the indemnifying party so desires, jointly with any other 
indemnifying party 

                                          4

similarly noticed, to assume the defense thereof with counsel mutually 
satisfactory to the parties; PROVIDED, HOWEVER, that an indemnified party 
shall have the right to retain its own counsel, with the fees and expenses to 
be paid by the indemnifying party, if representation of such indemnified 
party by the counsel retained by the indemnifying party would be 
inappropriate due to actual or potential differing interests between such 
indemnified party and any other party represented by such counsel in such 
proceeding.  The failure to deliver written notice to the indemnifying party 
within a reasonable time of the commencement of any such action, if 
prejudicial to its ability to defend such action, shall relieve such 
indemnifying party of any liability to the indemnified party under this 
Section 9, but the omission so to deliver written notice to the indemnifying 
party will not relieve it of any liability that it may have to any 
indemnified party otherwise than under this Section 9.

         10.  REPORTS UNDER THE 1934 ACT.  With a view to making available to 
Holder the benefits of Rule 144 promulgated under the Act and any other rule 
or regulation of the SEC that may at any time permit Holder to sell 
securities of the Company to the public without registration the Company will 
endeavor to:

              (a)  make and keep public information available, as those terms 
are understood and defined in SEC Rule 144;
                    
              (b)  take such action as is necessary to enable Holder to 
utilize an abbreviated registration statement for the sale of its Registrable 
Securities;
                    
              (c)  file with the SEC in a timely manner all reports and other 
documents required of the Company under the Act and the 1934 Act; and
                    
              (d)  furnish to Holder, so long as Holder owns any Registrable 
Securities, forthwith upon request (i) a written statement by the Company 
that it has complied with the reporting requirements of SEC Rule 144, the Act 
and the 1934 Act, or that it qualifies as a registrant whose securities may 
be resold pursuant to Form S-3 (at any time after it so qualifies), (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 in availing Holder of any rule or 
regulation of the SEC which permits the selling of any such securities 
without registration or pursuant to such form.

         11.  ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause the 
Company to register Registrable Securities pursuant to the Warrant may be 
assigned by Holder to a permitted transferee or assignee of the Warrant of 
all 150,000 Shares, provided the Company is, within a reasonable time after 
such transfer, furnished with written notice of the name and address of such 
transferee or assignee and the securities with respect to which such 
registration rights are being assigned; and provided, further, that such 
assignment shall be effective only if immediately following such transfer the 
further disposition of such securities by the transferee or assignee is 
restricted under the Act.

    PC QUOTE, INC., a corporation organized and existing under and by virtue

of the General Corporation Law of the State of Delaware (the "Corporation"),

DOES HEREBY CERTIFY THAT:


  FIRST:  The Board of Directors of the Corporation approved and adopted the 
following resolution for amending its Certificate of Incorporation, declaring 
it advisable and recommended that the amendment be submitted to the 
stockholders for their consideration:

    RESOLVED, that Article Fourth of the Company's Certificate of 
Incorporation be amended in its entirety, to read as follows:

"FOURTH:

  A.AUTHORIZED SHARES.  The total number of shares of all
    classes of stock which the Corporation shall have authority
    to issue is Fifty-five Million (55,000,000), consisting of
    Fifty Million (50,000,000) shares of Common Stock, $0.001
    par value per share (the "Common Stock"), and Five Million
    (5,000,000) shares of Preferred Stock, $0.001 par value per
    share (the "Preferred Stock").

  B.PREFERRED STOCK.  The Board of Directors is authorized,
    subject to any limitations prescribed by law, to provide
    for the issuance of shares of Preferred Stock in series,
    and by filing a certificate pursuant to the applicable law
    of the State of Delaware (such certificate being
    hereinafter referred to as a "Preferred Stock
    Designation"), to establish from time to time the number of
    shares to be included in each such series, and to fix the
    designations, powers, preferences and rights of the shares
    of each such series and any qualifications, limitations or
    restrictions thereof.  The


<PAGE>

    number of authorized shares of Preferred Stock may be increased 
    or decreased (but not below the number of shares thereof then 
    outstanding) by the affirmative vote of the holders of a majority 
    of the Common Stock, without a vote of the holders of the Preferred
    Stock, or of any series thereof, unless a vote of any such
    holders is required pursuant to the terms of any Preferred
    Stock Designation.

  C.COMMON STOCK.  Except as otherwise provided by the General
    Corporation Law of the State of Delaware, by this
    Certificate of Incorporation or any amendments hereto or by
    a Preferred Stock Designation, all of the voting power of
    the Corporation shall be vested in the holders of Common
    Stock, and each holder of Common Stock shall have one (1)
    vote for each share of Common Stock held by such holder on
    all matters voted upon by the stockholders."

  SECOND:  The amendment was duly adopted in accordance with the provisions 
of Section 242 of the General Corporation Law of the State of Delaware at the 
1997 Annual Meeting of Stockholders held on October 16, 1997.

  IN WITNESS WHEREOF, PC QUOTE, INC. has caused this Certificate to be

executed by its Chief Executive Officer this 21st day of October, 1997.

                       STOCK AND WARRANT PURCHASE AGREEMENT
                                           

    Agreement entered into as of October 15, 1997, by and between Imprimis 
Investors LLC, a limited liability company organized under the laws of the 
State of Delaware, and Wexford Spectrum Investors LLC, a limited liability 
company organized under the laws of the State of Delaware (each,

shares of Seller's Common Stock for an aggregate purchase price of up to $5 
million.  Up to four million of such shares of Common Stock shall be 
repurchased by Seller from Buyers under certain circumstances set forth 
herein at a purchase price of $1.00 per share.

provided or products manufactured or sold by Seller, nor any patents, 
formulae, processes, know-how, trade secrets, trademarks, trade names, 
assumed names, copyrights or designations used in its business, infringe on 
any patents, trademarks or copyrights, or any other rights of any person or 
corporate entity, and no claims have been made against Seller in such 
connection except as disclosed on Schedule 4(n) hereto.

    (s)  INSURANCE.  Schedule 4(s) hereto sets forth a complete and accurate 
list and description, including but not limited to annual premiums thereon 
and the deductibles thereunder, of all policies of fire, comprehensive 
general liability including product liability and worker's compensation 
insurance presently in effect with respect to Seller, two copies of which 
have heretofore been delivered to Buyer.  All such policies are valid, 
outstanding and enforceable policies and provide insurance coverage for the 
properties, assets and operations of Seller of the kinds, in the amounts and 
against the risks customarily maintained by organizations similarly situated. 
 Seller has not been refused any insurance with respect to any aspect of its 
operations, nor has its coverage been limited by any insurance carrier to 
which it has applied for insurance or with which it has carried insurance 
during the last three years.

    (t)  PRODUCTS.
         
         1.   Except as set forth in Schedule 4(t) hereto, there exists no 
set of facts (i) which could furnish a basis for the recall, withdrawal, 
suspension or cancellation of any product registration, product license, 
manufacturing license, wholesale dealers license, export license or other 
governmental license, approval or consent of any governmental or regulatory 
agency with respect to any product developed, manufactured, distributed or 
sold by Seller (a "Product"), (ii) which could furnish a basis for the 
recall, withdrawal or suspension by order of any state, federal or foreign 
court of law of any Product, or (iii) which could have a material adverse 
effect on the continued operation of any facility of Seller or which could 
otherwise cause Seller to recall, withdraw or suspend any such Product from 
the market or to change the marketing clarification of any such Product.
         
         2.   Each product manufactured by Seller has in all material 
respects been manufactured in accordance with the specifications under which 
such Product normally is and has been manufactured and the provisions of all 
applicable laws or regulations including, without limitation, any applicable 
governmental regulatory authorities.
         
    (u)  ENVIRONMENTAL PROTECTION.

         In connection with its business operations, Seller has obtained all 
permits, licenses and other authorizations which are required under federal, 
state and local laws relating to pollution or protection of the environment, 
including laws relating to emissions, discharges, releases or threatened 
releases of pollutants, contaminants, or hazardous or toxic materials or 
wastes into ambient air, surface water, ground water, or land, or otherwise 
relating to the manufacture, processing, distribution, use, treatment, 
storage, disposal, transport, or handling of pollutants, contaminants or 
hazardous or toxic materials or wastes; to the best of its knowledge after 
due investigation, Seller is in compliance in all material respects with all 

                                      13

terms and conditions of the required permits, licenses and authorizations, 
and is also in compliance in all material respects with all other 
limitations, restrictions, conditions, standards, prohibitions, requirements, 
obligations, schedules and timetables contained in those laws or contained in 
any regulation, code, plan, order, decree, judgment, notice or demand latter 
issued, entered, promulgated or approved thereunder.  Seller is not aware of, 
and has not received notice of, past, present or future events, conditions, 
circumstances, activities, practices, incidents, actions or plans which may 
interfere with or prevent continued compliance, or which may give rise to any 
common law or legal liability, or otherwise form the basis of any claim, 
action, suit, proceeding, hearing or investigation, based on or related to 
the manufacture, processing, distribution, use, treatment, storage, disposal, 
transport, or handling, or the omission, discharge, release or threatened 
release into the environment, of any pollutant, contaminant, or hazardous or 
toxic material or waste.

(including satisfaction, but not waiver, of the conditions precedent to closing
set forth in Section 2 and Section 7 hereof).

    (b)  NOTICES AND CONSENTS.  Seller will give any notices to third parties,

full access at all reasonable times, and in a manner so as not to interfere 
with the normal business operations of Seller, to all premises, properties, 
personnel, books, records (including tax records), contracts, and documents 
of or pertaining to Seller.  Buyers will treat and hold as such any 
Confidential Information received from Seller in the course of the reviews 
contemplated by this Section 5(d), will not use any of the Confidential

is terminated for any reason whatsoever, will return to Seller all tangible 
embodiments (and all copies) of the Confidential Information which are in its 
possession.

    (e)  NOTICE OFDEVELOPMENTS.  Seller shall notify Buyers of any

Section  4 above.  Unless Buyers have the right to terminate this Agreement 
pursuant to Section  9(a)(ii) below by reason of the development and exercise 
that right within the period referred to in Section  9(a)(ii) below, the 
written notice pursuant to this Section 5(e)(i) will be deemed to have 
amended the relevant Schedule, if any, to have 

                                      14

qualified the representations and warranties contained in Section  4 above,

might have existed hereunder by reason of the development.

    (f)  EXCLUSIVITY.  Until twenty-eight days from the date hereof, Seller
shall not solicit, initiate, or encourage the submission of any proposal or
offer from any Person relating to the acquisition of all or substantially all of

merger, consolidation, or share exchange); PROVIDED, HOWEVER, that Seller and
its directors and officers will remain free to participate in any discussions or
negotiations regarding, furnish any information with respect to, assist or
participate in, or facilitate in any other manner any effort or attempt by any
Person to do or seek any of the foregoing to the extent their fiduciary duties

    6.   POST-CLOSING COVENANTS.  The Parties agree as follows with respect to
the period following the Closing.

    (a)  GENERAL.  In case at any time after any Closing Date any further
action is necessary to carry out the purposes of this Agreement, each of the
Parties will take such further action (including the execution and delivery of
such further instruments and documents) as any other Party reasonably may
request, all at the sole cost and expense of the requesting party (unless the
requesting Party is entitled to indemnification therefor under Section 8 below).

    (b)  LITIGATION SUPPORT.  In the event and for so long as any Party

hearing, investigation, charge, complaint, claim, or demand in connection with
(i) any transaction contemplated under this Agreement or (ii) any fact,
situation, circumstance, status, condition, activity, practice, plan,
occurrence, event, incident, action, failure to act, or transaction on or prior
to any Closing Date involving Seller, each of the other Parties shall cooperate
with him or it and his or its counsel in the defense or contest, make available
their personnel, and provide such testimony and access to their books and
records as shall be necessary in connection with the defense or contest, all at
the sole cost and expense of Seller (unless the contesting or defending Party is
entitled to indemnification therefor under Section 8 below).

    (c)  RIGHTS OFFERING.  Seller shall use its best efforts to prepare, file 
with the Securities and Exchange Commission and have declared effective a 
Registration Statement covering an offering of rights to its existing 
stockholders (other than Buyers) to subscribe for the purchase of one 
additional Share for each Share of Seller owned by such stockholders as of 
the record date. In the event the Rights Offering is not completed on or 
before January 24, 1998, Buyers shall receive from the Escrow Agent 
Additional Warrants to purchase up to an aggregate of 250,000 shares.  In the 
event the Rights Offering is not completed on or before February 28, 1998, 
Buyers shall have the right, in their discretion, (i) to extend the time for 
completion of the Rights Offering, or (ii) to (A) terminate Seller's 
obligation to complete the Rights Offering and (B) terminate Seller's right 
to repurchase from Buyers four million of the 

                                      15

Shares for issuance upon the exercise of the Warrants and the other options,
etc. set forth in Schedule 4(b) hereto. 

    (f)  REGISTRATION RIGHTS.  As soon as practicable after the First Closing
Date, Seller shall use its best efforts to register with the Securities and
Exchange Commission one million of the Shares purchased by Buyers hereunder on a
Registration Statement on Form S-3 (if appropriate) and, in the event the Rights
Offering is not completed, to amend such Registration Statement to include the
remaining Shares purchased by Buyers hereunder.  Buyers agree to cooperate fully
in such registration effort.

copies of any and all resolutions adopted by the shareholders of Seller at 
the Shareholders Meeting.

    (h)  NEGATIVE COVENANTS.  Seller covenants and agrees that, until the
earlier of (i) such time as Seller completes the Rights Offering and repurchases
from Buyers four million Shares as contemplated by Section 6(d) hereof or (ii)
February 28, 1998, Seller will not do any of the following without the prior
written consent of Buyers, which shall not be unreasonably withheld:

         (i)   DISPOSITIONS.  Convey, sell, lease, transfer or otherwise dispose

    worn-out or obsolete equipment.

         (iv)  TRANSACTIONS WITH AFFILIATES.  Directly or indirectly enter into
    or permit to exist any material transaction with any Affiliate of Seller

<PAGE>

    or that are in the ordinary course of Seller's business, upon fair and

    judgment or enter into any settlement with respect to the Third Party Claim
    without the prior written consent of the Indemnified Party (not to be
