         WHEREAS, the Company has entered into (i) that certain Securities 
Purchase Agreement with the Warrant Holders dated as of October 14, 1997 (the 
"Purchase Agreement"), pursuant to which the Company agrees, among other 
things, to issue to the Warrant Holders warrants (the "Warrants") to purchase 
up to an aggregate of two hundred fifty thousand (250,000) shares of common 
stock, $.001 par value per share, of the Company (the "Common Stock," and the 
Common Stock issuable upon exercise of the Warrants being herein referred to

to which the Company agrees, among other things, to issue to GE warrants (the 
"GE Warrant") to purchase up to an aggregate of two hundred fifty hundred 
thousand (250,000) shares of Common Stock of the Company. Each Warrant shall 
be a warrant to purchase one (1) Warrant Share, unless and until adjusted 
pursuant to Section 10 hereof.  Certain terms used herein and not elsewhere 
defined are defined in the Purchase Agreement.
         
         NOW, THEREFORE, in consideration of the premises and the mutual 
agreements herein set forth, and for other good and lawful consideration, the 
receipt, sufficiency and adequacy of which are hereby acknowledged, the 
parties hereto agree as follows:
         
         SECTION 1.     WARRANT CERTIFICATE. 

         The certificates evidencing the Warrants (the "Warrant 
Certificates") to be delivered pursuant to this Agreement shall be in 
registered form only and shall be substantially in the form set forth in 
Exhibit A attached hereto.
         
         SECTION 2.     EXECUTION OF WARRANT CERTIFICATE. 

         (a)  The Warrant Certificates shall be signed on behalf of the 
Company by its Chairman of the Board of Directors (the "Board") or its 
President or a Vice President, and by its Secretary or an Assistant Secretary 
under its corporate seal.  Each such signature upon the Warrant Certificates 
may be in the form of a facsimile signature of the present or any future 
Chairman of the Board, President, Vice President, Secretary or Assistant 
Secretary, as the case may be, and may be imprinted or otherwise


                                      1



reproduced on the Warrant Certificates.  The seal of the Company may be in 
the form of a facsimile thereof and may be impressed, affixed, imprinted or 
otherwise reproduced on the Warrant Certificates.

         (b)  In case any officer of the Company who shall have signed any 
Warrant Certificate shall cease to be such officer before the Warrant 
Certificate so signed shall have been disposed of by the Company, such 
Warrant Certificate nevertheless may be delivered or disposed of as though 
such person had not ceased to be such officer of the Company; and any Warrant 
Certificate may be signed on behalf of the Company by any person who, at the 
actual date of the execution of such Warrant Certificate, shall be a proper 
officer of the Company to sign such Warrant Certificate, although at the date 
of the execution of this Agreement any such person was not such officer.
         
         SECTION 3.     REGISTRATION.

         The Company shall register the Warrant Certificates in a Warrant 
register to be maintained by the Company (the "Warrant Register") when 
Warrants are issued. The Company may deem and treat the registered holders of 
the Warrant Certificates as the absolute owners thereof (notwithstanding any 
notation of ownership or other writing thereon made by anyone) for all 
purposes and shall not be affected by any notice to the contrary.

         SECTION 4.     REGISTRATION OF TRANSFERS AND EXCHANGES.  

         (a)  The Company shall from time to time register the transfer of 
any outstanding Warrant Certificate in the Warrant Register upon surrender 
thereof accompanied by a written instrument or instruments of transfer in 
form satisfactory to the Company, duly executed by the registered holder or 
holders thereof or by the duly appointed legal representative thereof or by a 
duly authorized attorney. Upon any such registration of transfer, a new 
Warrant Certificate shall be issued to the transferee and the surrendered 
Warrant Certificate shall be canceled and disposed of by the Company.

         (b)  The Warrant Holders agree that prior to any proposed transfer 
of the Warrants or of the Warrant Shares, which transfer shall not be to any 
Person engaged in the Business, if such transfer is not made pursuant to an 
effective Registration Statement under the Securities Act of 1933, as amended 
(the "Securities Act"), the Warrant Holder(s) will, if requested by the 
Company, deliver to the Company:
         
              (1)  an investment representation letter reasonably 
          satisfactory to the Company signed by the proposed transferee;

              (2)  an agreement by such transferee to the impression of the 
          restrictive investment legend set forth below in Section 4(c) on 
          the Warrants or the Warrant Shares;

              (3)  an agreement by such transferee that the Company may place 
          a notation in the stock books of the Company or a "stop transfer 
          order" with any transfer agent or registrar with respect to the 
          Warrant Shares;

              (4)  an agreement by such transferee to be bound by the 
          provisions of this Section 4 relating to the transfer of such 
          Warrants or Warrant Shares; and

              (5)  except in the case of a transfer pursuant to Rule 144 
          promulgated pursuant to the Securities Act, or any successor rule, 
          prior to consummating any private sale or transfer of such Warrants 
          or Warrant Shares, the written opinion of reputable legal counsel 
          in form reasonably 


                                      2



          acceptable to the Company that such sale or transfer is being made 
          in compliance with applicable federal securities laws.

              (c)  The Warrant Holders agree that each certificate 
          representing Warrants or Warrant Shares will bear the following 
          legend until such Warrants or Warrant Shares have been sold 
          pursuant to an effective registration statement under the 
          Securities Act:

                   "THE SECURITIES EVIDENCED OR CONSTITUTED HEREBY HAVE 
                    BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN 
                    REGISTERED UNDER THE SECURITIES ACT OF 1933, AS 
                    AMENDED. SUCH SECURITIES MAY NOT BE SOLD, 
                    TRANSFERRED, PLEDGED, HYPOTHECATED OR OTHERWISE 
                    DISPOSED OF IN THE ABSENCE OF REGISTRATION UNDER 
                    SAID ACT AND THE RULES AND REGULATIONS THEREUNDER 
                    AND OF ALL APPLICABLE STATE SECURITIES OR "BLUE SKY" 
                    LAWS OR AN EXEMPTION THEREFROM UNDER SAID ACT AND 
                    ALL APPLICABLE STATE SECURITIES OR "BLUE SKY" LAWS.  
                    IN THE CASE OF A SALE OF THE SECURITIES EVIDENCED OR 
                    CONSTITUTED HEREBY, OTHER THAN A SALE PURSUANT TO A 
                    VALID REGISTRATION STATEMENT UNDER SAID ACT OR A 
                    SALE PURSUANT TO RULE 144 PROMULGATED UNDER SAID 
                    ACT, THE HOLDER OF THE SECURITIES EVIDENCED OR 
                    CONSTITUTED HEREBY SHALL PROVIDE TO THE CORPORATION 
                    THE WRITTEN OPINION OF REPUTABLE LEGAL COUNSEL IN 
                    FORM REASONABLY ACCEPTABLE TO THE CORPORATION THAT 
                    SUCH SALE OR TRANSFER IS BEING MADE IN COMPLIANCE 
                    WITH APPLICABLE FEDERAL SECURITIES LAWS."

         (d)  A Warrant Certificate may be exchanged at the option of the 
holder(s) thereof, when surrendered to the Company at its office for another 
Warrant Certificate or other Warrant Certificates of like tenor and 
representing in the aggregate a like number of Warrants. A Warrant 
Certificate surrendered for exchange shall be canceled and disposed of by the 
Company

         SECTION 5.     WARRANTS; EXERCISE OF WARRANTS.  

         (a)  Subject to the terms of this Agreement, the Warrant Holders 
shall have the right, which may be exercised during the period commencing on 
the Effective Date until 5:00 p.m., Washington, D.C. time, on the fifth 
anniversary of the Effective Date (the "Exercise Period"), to receive from 
the Company the number of fully paid and non-assessable Warrant Shares that 
the Warrant Holder may at the time be entitled to receive on exercise of the 
number of Warrants that the Warrant Holder elects to exercise and payment of 
the Exercise Price (as defined below) then in effect for such Warrant Shares. 
 In the alternative, the Warrant Holder may exercise its right, during the 
Exercise Period, to receive Warrant Shares on a net basis, such that, without 
payment of any funds kind, the Warrant Holder receives that number of Warrant 
Shares equal to the number of Warrants being exercised times the quotient of 
(i) the "fair market value" of a Warrant Share (as defined below) minus the 
Exercise Price, divided by (ii) the fair market value of a Warrant Share.  
For purposes of the foregoing sentence, "fair market value" of a Warrant 
Share shall mean the average of the closing prices of the Common Stock's 
sales on all domestic 


                                      3


securities exchanges on which such Common Stock may at the time be listed, 
or, if there have been no sales on any such exchange on any day, the average 
of the highest bid and lowest asked prices on all such exchanges at the end 
of such day, or, if on any day such Common Stock is not so listed, the 
average of the representative bid and asked prices quoted on Nasdaq as of 
4:00 P.M., New York time, on such day, or, if on any day such Common Stock is 
not quoted on Nasdaq, the average of the highest bid and lowest asked prices 
on such day in the domestic over-the-counter market as reported by the 
National Quotation Bureau, Incorporated, or any similar successor 
organization, in each such case averaged over a period of twenty-one (21) 
business days consisting of the day as of which the "fair market value" of 
the Warrant Shares is being determined and the twenty (20) consecutive 
business days prior to such day; provided that if such Common Stock is listed 
on any domestic securities exchange the term "business days" as used in this 
sentence means business days on which such exchange is open for trading.  If 
at any time such Common Stock is not listed on any domestic securities 
exchange or quoted on Nasdaq or the domestic over-the-counter market, the 
"fair market value" of the Warrant Shares shall be the fair value thereof 
determined by the Company and approved by the Warrant Holder; provided that 
if such parties are unable to reach agreement within a reasonable period of 
time, such fair market value shall be determined by an appraiser reasonably 
selected by the Company and reasonably approved by the Warrant Holder.  The 
determination of such appraiser shall be final and binding on the Company and 
the Warrant Holder, and the fees and expenses of such appraiser shall be paid 
by the Company, unless the fair market value determined by such appraiser is 
less than five percent (5%) above the value proposed in writing by the 
Company and rejected by the Warrant Holder prior to the selection of such 
appraiser, in which event the fees and expenses of such appraiser shall be 
for the Warrant Holder's account.  Each Warrant not exercised prior to 5:00 
p.m., Washington, D.C. time, on the fifth anniversary of the Effective Date 
shall become void and all rights thereunder and all rights in respect thereof 
under this agreement shall cease as of such time.  No adjustments as to 
dividends will be made upon exercise of the Warrants.

         (b)  A Warrant may be exercised upon surrender to the Company at its 
office designated for such purpose (the address of which is set forth in 
Section 14 hereof) of the certificate or certificates evidencing the Warrants 
to be exercised with the form of election to purchase on the reverse thereof 
duly filled in and signed, and upon (i) payment to the Company of the 
exercise price of ten dollars ($10.00) per Warrant Share, as adjusted as 
herein provided (as so adjusted, the "Exercise Price"), for the number of 
Warrant Shares in respect of which such Warrants are then exercised, or (ii) 
the Warrant Holder's exercise of its right to receive Warrant Shares on a net 
basis, as more fully described in Section 5(a).  Payment of the aggregate 
Exercise Price shall be made (i) in cash or by certified or official bank 
check payable to the order of the Company or (ii) in the manner provided in 
subsection (a) of this Section 5.
         
         (c)  Subject to the provisions of Section 6 hereof, upon such 
surrender of Warrants and payment of the Exercise Price, the Company shall 
issue and cause to be delivered with all reasonable dispatch to or upon the 
written order of the Warrant Holder and in such name or names as the Warrant 
Holder may designate, a certificate or certificates for the number of full 
Warrant Shares issuable upon the exercise of such Warrants together with cash 
as provided in Section 11; PROVIDED, HOWEVER, that if any consolidation, 
merger, or sale or other transfer of all or substantially all of the assets 
of the Company is proposed to be effected by the Company, or a tender offer 
or an exchange offer for shares of Common Stock of the Company shall be made, 
upon such surrender of Warrants and payment of the Exercise Price as 
aforesaid, the Company shall, as soon as practicable, but in any event not 
later than five business days thereafter, issue and cause to be delivered the 
full number of Warrant Shares issuable upon the exercise of such Warrants in 
the manner described in this sentence together with cash as provided in 
Section 11.  Such certificate or certificates shall be deemed to have been 
issued and any person so designated to be named therein shall be deemed to 
have become a holder of record of such Warrant Shares as of the date of the 
surrender of such Warrants and payment of the Exercise Price.


                                      4         



         (d)  The Warrants shall be exercisable, at the election of the 
holder thereof, either in full or from time to time in part and, in the event 
that a Warrant Certificate evidencing Warrants is exercised in respect of 
fewer than all of the Warrant Shares issuable on such exercise at any time 
prior to the date of expiration of the Warrants, a new Warrant Certificate 
evidencing the remaining Warrant or Warrants will be issued and delivered by 
the Company and at its expense pursuant to the provisions of this Section and 
of Section 2 hereof.
         
         (e)  All Warrant Certificates surrendered upon exercise of Warrants 
shall be canceled and disposed of by the Company. The Company shall keep 
copies of this Agreement and any notices given or received hereunder 
available for inspection by the Warrant Holder during normal business hours 
at its office.

          SECTION 6.     PAYMENT OF TAXES. 

          The Company will pay all documentary stamp taxes or other similar 
taxes attributable to the initial issuance of Warrant Shares upon the 
exercise of Warrants; PROVIDED, HOWEVER, that the Company shall not be 
required to pay any tax or taxes which may be payable in respect of any 
transfer involved in the issue of any Warrant Certificate or any certificates 
for Warrant Shares in a name other than that of the registered holder of a 
Warrant Certificate surrendered upon the exercise of a Warrant, and the 
Company shall not be required to issue or deliver such Warrant Certificates 
unless or until the person or persons requesting the issuance thereof shall 
have paid to the Company the amount of such tax or shall have established to 
the satisfaction of the Company that such tax has been paid.

         SECTION 7.     MUTILATED OR MISSING WARRANT CERTIFICATES.  
         
         In case any of the Warrant Certificates shall be mutilated, lost, 
stolen or destroyed, the Company may issue, in exchange and substitution for, 
and upon cancellation of, the mutilated Warrant Certificate, or in lieu of 
and substitution for the Warrant Certificate lost, stolen or destroyed, a new 
Warrant Certificate of like tenor and representing an equivalent number of 
Warrants, but only upon receipt of evidence reasonably satisfactory to the 
Company of such loss, theft or destruction of such Warrant Certificate and 
indemnity, if requested, also reasonably satisfactory to it. Applicants for 
such substitute Warrant Certificates shall also comply with such other 
reasonable regulations and pay such other reasonable charges as the Company 
may prescribe.
         
         SECTION 8.     RESERVATION OF WARRANT SHARES. 
   
         (a)  The Company will at all times reserve and keep available, free 
from preemptive rights, out of the aggregate of its authorized but unissued 
Common Stock or its authorized and issued Common Stock held in its treasury, 
for the purpose of enabling it to satisfy any obligation to issue Warrant 
Shares upon exercise of Warrants, the maximum number of shares of Common 
Stock which may then be deliverable upon the exercise of all outstanding 
Warrants.
 
         (b)  The Company or, if appointed, the transfer agent for the Common 
Stock (the "Transfer Agent") and every subsequent Transfer Agent for any 
shares of the Company's capital stock issuable upon the exercise of any of 
the rights of purchase aforesaid will be irrevocably authorized and directed 
at all times to reserve such number of authorized shares as shall be required 
for such purpose. The Company will keep a copy of this Agreement on file with 
the Transfer Agent and with every subsequent transfer agent for any shares of 
the Company's capital stock issuable upon the exercise of the rights of 
purchase 


                                      5



represented by the Warrants.  The Company will furnish such Transfer 
Agent a copy of all notices of adjustments and certificates related thereto 
transmitted to each holder pursuant to Section 13 hereof.
         
         (c)  Before taking any action which would cause an adjustment 
pursuant to Section 10 hereof to reduce the Exercise Price below the then par 
value (if any) of the Warrant Shares, the Company will take any corporate 
action which may, in the opinion of its counsel (which may be counsel 
employed by the Company), be necessary in order that the Company may validly 
and legally issue fully paid and nonassessable Warrant Shares at the Exercise 
Price as so adjusted.
         
        (d)  The Company covenants that all Warrant Shares which may be 
issued upon exercise of Warrants will, upon issue, be fully paid, 
nonassessable, free of preemptive rights and free from all taxes, liens, 
charges and security interests with respect to the issue thereof

         SECTION 9.     STOCK EXCHANGE LISTINGS. 

         The Company will from time to time take all commercially reasonable 
action, at its expense, which may be necessary so that the Warrant Shares, 
immediately upon their issuance upon the exercise of Warrants, will be listed 
and maintained on the principal securities exchanges and markets within the 
United States of America, if any, on which other shares of Common Stock are 
then listed and registered under the Securities Exchange Act of 1934, as 
amended (the "Exchange Act"), or authorized for quotation on Nasdaq, 
provided, however, that the payment of any required listing or other fee 
shall always be deemed to be "commercially reasonable" for purposes of this 
Section 9.

         SECTION 10.  ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES
ISSUABLE.  
         
         (a)  In order to prevent the dilution of the rights granted under 
this Agreement, the Exercise Price shall be subject to adjustment from time 
to time as provided in this Section 10, and the number of shares of Common 
Stock obtainable upon exercise of the Warrants shall be subject to adjustment 
from time to time as provided in this Section 10.  For purposes of this 
Section 10, "Trigger Price" shall be $6.75 per share of Common Equity; 
"Convertible Security" means any stock or securities, directly or indirectly, 
convertible into or exchangeable for Common Equity, including without 
limitation any exchangeable debt securities; "Option" shall mean any rights 
or options to subscribe for or purchase Common Equity or Convertible 
Securities.
   
         (b)  If and whenever the Company issues or sells or, in accordance 
with Section 10(c), is deemed to have issued or sold, any share of Common 
Equity without consideration or for a net consideration per share less than 
the Trigger Price, then immediately upon such issuance or sale, the Exercise 
Price, which shall equal $10 per share until the first such issuance or sale 
below the Trigger Price, shall be reduced to the price per share determined 
by dividing (i) an amount equal to the sum of (A) the number of shares of 
Common Equity outstanding immediately prior to such issuance multiplied by 
the Exercise Price in effect immediately prior to such issuance, and (B) the 
consideration, if any, received by the Company upon such issuance, by (ii) 
the total number of shares of Common Equity outstanding immediately after 
such issuance.  
         
         Notwithstanding the foregoing, there shall be no adjustment to the 
Exercise Price with respect to the granting of, or issuance of Common Equity 
upon exercise of, stock options to employees of the Company authorized but 
not granted as of the Effective Date for an aggregate of up to 300,000 shares 
of Common Equity (as such shares are equitably adjusted for subsequent stock 
splits, stock combinations, stock dividends and recapitalizations).  For 
purposes of this Section 10, "Common Equity" means all 


                                      6



shares now or hereafter authorized of any class of common stock of the 
Company (including the Common Stock) and any other stock of the Company, 
however designated, authorized on or after the date hereof, which has the 
right (subject always to prior rights of any class or series of preferred 
stock) to participate in any distribution of the assets or earnings of the 
Company without limit as to per share amount, and "Fully Diluted Equity" 
means, with respect to the Company at any given time, (A) the number of 
shares of Common Equity actually outstanding at such time, plus (B) the 
maximum number of shares of Common Equity that are issuable upon the 
exercise, exchange or conversion of any unexpired right or unexpired option 
(including the Warrants) to subscribe for, to purchase or to receive Common 
Equity or other securities convertible into or exchangeable for Common 
Equity, including without limitation any exchangeable debt securities, 
regardless of whether any of the foregoing are actually exercisable at such 
time; provided, however, the number of shares of Common Equity outstanding at 
any given time shall not include shares, directly or indirectly, owned or 
held by or for the account of the Company.
      
         (c)  For purposes of determining the adjusted Exercise Price under 
Section 10(b) above, the following shall be applicable:
      
              (1)  CONSIDERATION.  If any Common Equity, Options or Convertible
          Securities are issued or sold or deemed to have been issued or sold 
          for cash, the consideration received therefor shall be deemed to be 
          (i) in the case of any public offering of such securities for cash, 
          the gross proceeds of such offering (without deduction for any 
          underwriters discount) and (ii) in the case of any other issuance, 
          sale or deemed issuance or sale for cash, the gross amount received 
          by the Company therefor.  In case any Common Equity, Options or 
          Convertible Securities are issued or sold for a consideration other 
          than cash, the amount of the consideration other than cash received 
          by the Company shall be the fair market value of such consideration.
          In case any Common Equity, Options or Convertible Securities are 
          issued to the owners of the non-surviving entity in connection with 
          any merger in which the Company is the surviving corporation, the 
          amount of consideration therefor shall be deemed to be the fair 
          market value of such portion of the net assets and business of the 
          non-surviving entity as is attributable to such Common Equity, 
          Options or Convertible Securities, as the case may be.  The fair 
          market value of any consideration other than cash shall be 
          determined jointly by the Company and a majority in interest of the 
          Warrant Holders.  If such parties are unable to reach agreement 
          within a reasonable period of time, such fair market value shall be 
          determined by an appraiser reasonably selected by the Company and 
          reasonably approved by such Warrant Holders.  The determination of 
          such appraiser shall be final and binding on the Company and the 
          Warrant Holders, and the fees and expenses of such appraiser shall 
          be paid by the Company, unless the fair market value determined by 
          such appraiser is less than five percent (5%) above the value 
          proposed in writing by the Company and rejected by such Warrant 
          Holders prior to the selection of such appraiser, in which event the 
          fees and expenses of such appraiser shall be for such Warrant 
          Holders' account.

              (2)  OPTIONS AND CONVERTIBLE SECURITIES.  In the case of the 
          granting or sale of any Option or Convertible Security (whether or 
          not at the time convertible, exercisable or exchangeable):

               (A)  the aggregate maximum number of shares of Common Equity 
               deliverable, directly or indirectly, upon exercise of any 
               Option shall be deemed to have been issued at the time such 
               Option was granted and for a consideration equal to the 
               consideration (determined in the manner provided in subsection 
               (1) above), if any, received by the Company upon the issuance 
               of 


                                      7



               such Option plus the minimum purchase price provided in such 
               Option for the Common Equity covered thereby;

               (B)  the aggregate maximum number of shares of Common Equity 
               deliverable upon conversion of or in exchange for any such 
               Convertible Security, or upon the exercise of any Option to 
               purchase or acquire any Convertible Security and the subsequent 
               conversion or exchange thereof, shall be deemed to have been 
               issued at the time such Convertible Security was issued or such 
               Option was issued and for a consideration equal to the 
               consideration, if any, received by the Company for any such 
               Convertible Security and any related Option (excluding any cash 
               received on account of accrued interest or accrued dividends), 
               plus the additional consideration (determined in the manner 
               provided in subsection (1) above), if any, to be received by 
               the Company upon the conversion or exchange of such Convertible 
               Security, or upon the exercise of any related Option to purchase
               or acquire any Convertible Security and the subsequent 
               conversion or exchange thereof;

               (C)  on any change in the number of shares of Common Equity 
               deliverable, directly or indirectly, upon conversion, exercise 
               or exchange of any such Option or Convertible Security or any 
               change in the consideration to be received by the Company upon 
               such exercise, conversion or exchange, including, but not 
               limited to, a change resulting from the anti-dilution provisions
               thereof, the Exercise Price as then in effect shall forthwith 
               be readjusted to such Exercise Price as would have been obtained
               had an adjustment been made upon the issuance of such Option or 
               Convertible Security upon the basis of such change;and

               (D)  if the Exercise Price shall have been adjusted upon the 
               issuance of any such Option or Convertible Security, no further 
               adjustment of the Exercise Price shall be made for the actual 
               issuance of Common Equity upon any exercise, conversion, or 
               exchange thereof;

provided, however, that none of the events set forth in Section 10(c)(2)(A) 
through 10(c)(2)(D), inclusive, shall result in any increase in the Exercise 
Price.

     (3)  INTEGRATED TRANSACTION.  In case any Option is issued in connection 
with the issue or sale of other securities of the Company, together 
comprising one integrated transaction in which no specific consideration is 
allocated to such Options by the parties thereto, the Options shall be deemed 
to have been issued without consideration.

     (4)  TREASURY SHARES.  The number of shares of Common Equity outstanding 
at any given time does not include shares owned or held by or for the account 
of the Company, and the disposition of any shares so owned or held shall be 
considered an issuance or sale of Common Equity.

     (5)  RECORD DATE.  If the Company takes a record of the holders of 
Common Equity for the purpose of entitling them (A) to receive a dividend or 
other distribution payable in Common Equity, Options or in Convertible 
Securities or (B) to subscribe for or purchase 


                                      8

 
          Common Equity, Options or Convertible Securities, then such record 
          date shall be deemed to be the date of the issuance or sale of the 
          shares of Common Equity deemed to have been issued or sold upon the 
          declaration of such dividend or the making of such other 
          distribution or the date of the granting of such right of 
          subscription or purchase, as the case may be.

         (d)  If the Company at any time subdivides (by any stock split, 
stock dividend, recapitalization or otherwise) one or more classes of its 
outstanding shares of Common Equity into a greater number of shares, the 
Exercise Price in effect immediately prior to such subdivision shall be 
proportionately reduced and the number of shares of Common Stock obtainable 
upon exercise of the Warrant shall be proportionately increased.  If the 
Company at any time combines (by reverse stock split or otherwise) one or 
more classes of its outstanding shares of Common Stock into a smaller number 
of shares, the Exercise Price in effect immediately prior to such combination 
shall be proportionately increased and the number of shares of Common Stock 
obtainable upon exercise of this Warrant shall be proportionately decreased.

         (e)  Any recapitalization, reorganization, reclassification, 
consolidation, merger, sale of all or substantially all of the Company's 
assets or other transaction, in each case which is effected in such a way 
that the holders of Common Equity are entitled to receive (either directly or 
upon subsequent liquidation) stock, securities or assets with respect to or 
in exchange for Common Equity is referred to herein as a "Corporate Change."  
Prior to the consummation of any Corporate Change, the Company shall make 
appropriate provision (in form and substance satisfactory to the Warrant 
Holder) to insure that the Warrant Holder shall thereafter have the right to 
acquire and receive, in lieu of or in addition to (as the case may be) the 
Warrant Shares acquirable and receivable upon the exercise of such holder's 
Warrants, such shares of stock, securities or assets as may be issued or 
payable with respect to or in exchange for the number of Warrant Shares 
acquirable and receivable upon exercise of such holder's Warrant had such 
Corporate Change not taken place.  In any such case, the Company shall make 
appropriate provision (in form and substance reasonably satisfactory to the 
Warrant Holder) with respect to such holder's rights and interests to insure 
that the provisions of this Agreement shall thereafter be applicable to the 
Warrants (including, in the case of any such consolidation, merger or sale in 
which the successor entity or purchasing entity is other than the Company, 
any adjustment of the Exercise Price based on Section 10 hereof).  The 
Company shall not effect any such consolidation, merger or sale, unless prior 
to the consummation thereof, the successor entity (if other than the Company) 
resulting from consolidation or merger or the entity purchasing such assets 
assumes by written instrument (in form and substance reasonably satisfactory 
to the Warrant Holder), the obligation to deliver to the Warrant Holder such 
shares of stock, securities or assets as, in accordance with the foregoing 
provisions, such holder may be entitled to acquire.
         
        (f)  If any event occurs of the type contemplated by the provisions 
of this Section 10 but not expressly provided for by such provisions 
(including, without limitation, the granting of stock appreciation rights, 
phantom stock rights or other rights with equity features), then the 
Company's Board shall make an appropriate adjustment in the Exercise Price 
and the number of shares of Common Stock obtainable upon exercise of this 
Warrant so as to protect the rights of the Warrant Holder; provided that no 
such adjustment shall increase the Exercise Price or decrease the number of 
shares of Common Stock obtainable as otherwise determined pursuant to this 
Section 10.
      
      (g)  If the Company declares or pays a dividend upon the Common Equity 
payable otherwise than in cash out of earnings or earned surplus (determined 
in accordance with generally accepted accounting principles, consistently 
applied) except for a stock dividend payable in shares of Common Stock (a 
"Liquidating Dividend"), then the Company shall pay to the Warrant Holder at 
the time of


                                      9



payment thereof the Liquidating Dividend which would have been paid to such
Warrant Holder on the Common Stock had the Warrants been fully exercised
immediately prior to the date on which a record is taken for such Liquidating
Dividend, or, if no record is taken, the date as of which the record holders of
Common Equity entitled to such dividends are to be determined.

               SECTION 11.  FRACTIONAL INTERESTS. 

               The Company shall not be required to issue fractional Warrant 
Shares upon the exercise of Warrants.  If more than one Warrant shall be 
presented for exercise in full at the same time by the Warrant Holder, the 
number of full Warrant Shares which shall be issuable upon the exercise 
thereof shall be computed on the basis of the aggregate number of Warrant 
Shares purchasable on exercise of the Warrants so presented.  If any fraction 
of a Warrant Share would, except for the provisions of this Section 11, be 
issuable on the exercise of any Warrants (or specified portion thereof), the 
Company shall pay an amount in cash equal to the "fair market value" 
(determined as provided in Section 5(a) above) of the Common Stock on the day 
immediately preceding the date the Warrant is presented for exercise, 
multiplied by such fraction.

               SECTION 12.  FINANCIAL STATEMENTS.

               (a)  Whether or not required by the rules and regulations of 
the Securities and Exchange Commission (the "Commission"), so long as any of 
the Warrants remain outstanding, the Company shall furnish to the Warrant 
Holders (i) all quarterly and annual financial information that would be 
required to be contained in a filing with the Commission on Forms 10-Q and 
10-K if the Company were required to file such Forms, including "Management's 
Discussion and Analysis of Financial Condition and Results of Operations" 
and, with respect to the annual information only, a report thereon by the 
Company's certified independent accountants and (ii) all current reports that 
would be required to be filed with the Commission on Form 8-K if the Company 
were required to file such reports. In addition, whether or not required by 
the rules and regulations of the Commission, the Company shall file a copy of 
all such information and reports with the Commission for public availability 
(unless the Commission will not accept such a filing).

               (b)  The Company shall, so long as any of the Warrants are 
outstanding, deliver to the Warrant Holders, forthwith upon any Executive 
Officer of the Corporation becoming aware of any default under this 
Agreement, an Officers' Certificate specifying such default and what action 
the Company is taking or proposes to take with respect thereto.

               SECTION 13.  NOTICES TO WARRANT HOLDERS.  

               (a)  Upon any adjustment of the Exercise Price or exercise 
privileges pursuant to Section 10, the Company shall promptly thereafter (i) 
cause to be filed with the Company a certificate of a firm of independent 
public accountants of recognized standing, selected by the Board (who may be 
the regular auditors of the Company) and acceptable to the Warrant Holders, 
setting forth the Exercise Price after such adjustment and setting forth in 
reasonable detail the method of calculation and the facts upon which such 
calculations are based and setting forth the number of Warrant Shares (or 
portion thereof) issuable after such adjustment in the Exercise Price, which 
certificate shall be conclusive evidence of the correctness of the matters 
set forth therein, upon exercise of a Warrant and payment of the adjusted 
Exercise Price, and (ii) cause to be given to each of the registered holders 
of the Warrant Certificate(s), at his or her address appearing on the Warrant 
register, written notice of such adjustments by first-class 


                                       10




mail, postage prepaid.  Where appropriate, such notice may be given in 
advance and included as a part of the notice required to be mailed under the 
other provisions of this Section 13.

               (b)  In case:

                    (1)  the Company shall authorize the issuance to all holders
               of shares of Common Stock of the Company rights to subscribe for,
               or to purchase shares of, Common Stock or of any other 
               subscription rights or warrants; or

                    (2)  the Company shall authorize the distribution to all 
               holders of shares of Common Stock of evidences of its 
               indebtedness or assets; or

                    (3)  of any consolidation or merger to which the Company is
               a party and for which approval of any shareholders of the Company
               is required, or of the conveyance or transfer of the properties 
               and assets of the Company substantially as an entirety, or of 
               any reclassification or change of Common Stock issuable upon 
               exercise of the Warrants, or a tender offer or exchange offer 
               for shares of Common Stock; or

                    (4)  of the voluntary or involuntary dissolution, 
               liquidation or winding up of the Company or a Liquidating 
               Dividend; or

                    (5)  the Company proposes to take any action which would 
               require an adjustment of the Exercise Price or the Warrant 
               Shares pursuant to Section 10;

then the Company shall cause to be given to each of the registered holders of 
the Warrant Certificates at his or her address appearing on the Warrant 
register, at least twenty (20) days prior to the applicable record date 
hereinafter specified, or promptly in the case of events for which there is 
no record date, by first-class mail, postage prepaid, a written notice 
stating (i) the date as of which the holders of record of shares of Common 
Stock to be entitled to receive any such rights or distribution are to be 
determined, or (ii) the initial expiration date set forth in any tender offer 
or exchange offer for shares of Common Stock, or (iii) the date on which any 
such consolidation, merger, conveyance, transfer, dissolution, liquidation or 
winding up is expected to become effective or consummated, and the date as of 
which it is expected that holders of record of shares of Common Stock shall 
be entitled to exchange such shares for securities or other property, if any, 
deliverable upon such reclassification, consolidation, merger, conveyance, 
transfer, dissolution, liquidation or winding up.  The failure to give the 
notice required by this Section 13 or any defect therein shall not affect the 
legality or validity of any distribution, right, option, warrant, 
consolidation, merger, conveyance, transfer, dissolution, liquidation or 
winding up, or the vote upon any action.

               (c)  Nothing contained in this Agreement or in the Warrant 
Certificate shall be construed as conferring upon the holders thereof the 
right to vote or to consent or to receive notice as shareholders in respect 
of the meetings of shareholders or the election of Directors of the Company 
or any other matter, or any rights whatsoever as shareholders of the Company.

               SECTION 14.  NOTICES TO THE COMPANY AND THE WARRANT HOLDERS. 

               (a)  Unless otherwise provided herein, any notice, request,

shall be in writing and delivered by hand-delivery, registered first-class 
mail, return receipt requested, facsimile or air courier guaranteeing

Agreement with the express written approval of the holder(s) of the Warrant

or questions arising hereunder which the Company may deem necessary or 
desirable and which shall not in any way adversely affect the interests of 
the holder(s) of Warrant Certificate(s).

                                       12




               SECTION 16.  SUCCESSORS.

               All the covenants and provisions of this Agreement by or for 
the benefit of the Company shall bind and inure to the benefit of its 
respective successors and assigns hereunder.  All the covenants and 
provisions by or for the benefit of the Warrant Holders shall bind and inure

               SECTION 17.  TERMINATION.  

               This Agreement shall terminate at 5:00 p.m., Eastern Standard 
Time on the fifth anniversary of the Effective Date. Notwithstanding the 
foregoing, this Agreement will terminate on any earlier date if all Warrants 
have been exercised.

               SECTION 18.  GOVERNING LAW. 

               This Agreement and each Warrant Certificate issued hereunder

exercise any Warrants, in making all filings required to be made under the 
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR 
Act") in connection with such exercise; provided, however, that in no event 
shall such cooperation include payment of any fee which may be required to be 
paid.  The applicable waiting period, including any extension thereof, under

any Warrant Shares upon exercise of Warrants.

               SECTION 21.  COUNTERPARTS.

               This Agreement may be executed in any number of

expiring October 14, 2002 (the "Expiration Date") to purchase Common Stock, 
$.001 par value (the "Common Stock"), of InSight Health Services Corp., a

exercise to receive from the Company on or before 5:00 p.m., Washington, D.C. 
time, on the Expiration Date, one fully paid and non-assessable share of 
Common Stock (a "Warrant Share") at the initial exercise price of $10.00 per

"Exercise Price") upon the occurrence of certain events set forth in the 
Warrant Agreement, upon surrender of this Warrant Certificate and payment of 
the Exercise Price, or as otherwise provided in the Warrant Agreement, at the 
office of the Company designated for such purpose, but only subject to the 
conditions set forth herein and in the Warrant Agreement dated as of October 
14, 1997 (the "Warrant Agreement").  The number and kind of Warrant Shares 
issuable upon exercise of the Warrants are subject to adjustment upon the 
occurrence of certain events set forth in the Warrant Agreement.

     No Warrant may be exercised after 5:00 p.m., Washington, D.C. time, on the
Expiration Date, and to the extent not exercised by such time such Warrants
shall become void.

     Reference is hereby made to the further provisions of this Warrant 
Certificate set forth on the reverse hereof and such further provisions shall 
for all purposes have the same effect as though fully set forth at this place.

Company, as such term is used in the Warrant Agreement.

signed by its President and by its Secretary and has caused its corporate seal
to be affixed hereunto or imprinted hereon.

                            [FORM OF WARRANT CERTIFICATE]

                                      [REVERSE]

     The Warrants evidenced by this Warrant Certificate are part of a duly 
authorized issue of Warrants expiring on the Expiration Date, entitling the 
holder on exercise to receive shares of Common Stock, $.001 par value, of the 
Company (the "Common Stock"), and are issued or to be issued pursuant to the 
Warrant Agreement, duly executed and delivered by the Company, which Warrant 
Agreement is hereby incorporated by reference in and made a part of this 
instrument and is hereby referred to for a description of the rights, 
limitation of rights, obligations, duties and immunities thereunder of the 
Company and the holders (the words "holders" or "holder" meaning the 
registered holders or registered holder) of the Warrants (the "Warrant 
Holders"). A copy of the Warrant Agreement may be obtained by the holder 
hereof upon written request to the Company.

     Warrants may be exercised at any time on or before the Expiration Date. 
The holder of Warrants evidenced by this Warrant Certificate may exercise 
them by surrendering this Warrant Certificate, with the form of election to 
purchase set forth herein properly completed and executed, together with 
payment of the Exercise Price in cash at the office of the Company designated 
for such purpose. In the alternative, each Warrant Holder may exercise its 
right, during the Exercise Period, as defined in the Warrant Agreement, to 
receive Warrant Shares on a net basis, such that, without the exchange of any 
funds, the Warrant Holder receives that number of Warrant Shares otherwise 
issuable (or payable) upon exercise of its Warrants less that number of 
Warrant Shares having an aggregate fair market value (as defined below) at 
the time of exercise equal to the aggregate Exercise Price that would 
otherwise have been paid by the Warrant Holder of the Warrant Shares.  For 
purposes of the foregoing sentence, "fair market value" of the Warrant Shares 
will be determined in the manner set forth in the Warrant Agreement.  In the 
event that upon any exercise of Warrants evidenced hereby the number of 
Warrants exercised shall be less than the total number of Warrants evidenced 
hereby, there shall be issued to the holder hereof or his assignee a new 
Warrant Certificate evidencing the number of Warrants not exercised. Except 
as provided in Section 10 of the Warrant Agreement, no adjustment shall be 
made for any dividends on any Common Stock issuable upon exercise of this 
Warrant.

     The Warrant Agreement provides that, upon the occurrence of certain 
events, the Exercise Price and the number of Warrant Shares set forth on the 
face hereof may, subject to certain conditions, be adjusted. No fractions of 
a share of Common Stock will be issued upon the exercise of any Warrant, but 
the Company will pay the cash value thereof determined as provided in the 
Warrant Agreement. 

     The holders of the Warrants are entitled to certain registration rights 
with respect to the Common Stock purchasable upon exercise thereof.  Said 
registration rights are set forth in full in a Registration Rights Agreement 
dated as of October 14, 1997, between the Company and the Warrant Holder.  A 
copy of the Registration Rights may be obtained by the holder hereof upon 
written request to the Company.

     Warrant Certificates, when surrendered at the office of the Company by 
the registered holder thereof in person or by legal representative or 
attorney duly authorized in writing, may be exchanged, in the manner and 
subject to the limitations provided in the Warrant Agreement, but without 
payment of any service charge, for another Warrant Certificate or Warrant 
Certificates of like tenor evidencing in the aggregate a like number of 
Warrants.

                                      iii


     Upon due presentation for registration of transfer of this Warrant 
Certificate at the office of the Company, a new Warrant Certificate or 
Warrant Certificates of like tenor and evidencing in the aggregate a like 
number of Warrants shall be issued to the transferee(s) in exchange for this 
Warrant Certificate, subject to the limitations provided in the Warrant 
Agreement, without charge except for any tax or other governmental charge 
imposed in connection therewith.

     The Company may deem and treat the registered holder(s) thereof as the 
absolute owner(s) of this Warrant Certificate (notwithstanding any notation 
of ownership or other writing hereon made by anyone), for the purpose of any 
exercise hereof, of any distribution to the holder(s) hereof, and for all 
other purposes, and the Company shall not be affected by any notice to the 
contrary. Neither the Warrants nor this Warrant Certificate entitles any 
holder hereof to any rights of a stockholder of the Company.
