period commencing on the first anniversary of the Effective Date and ending 
at 5 p.m. Pacific Time on the fifth anniversary of the Effective Date by 
surrendering the Warrant Certificate, together with appropriate instructions, 
duly executed by the Warrantholder or by its duly authorized attorney, at the 
office of the Company, 2175 Broadbent Parkway, NE, Albuquerque, New Mexico 
87107, or at such other office or agency as the Company may designate. Upon 
receipt of notice of exercise, the Company shall immediately instruct its 
transfer agent to prepare certificates for the Securities to be received by 
the Warrantholder upon completion of the Warrant exercise. When such 
certificates are prepared, the Company shall notify the Warrantholder and 
deliver such certificates to the Warrantholder (or as otherwise designated by 
the Warrantholder's written instructions) immediately upon payment in full by 
the Warrantholder, in lawful money of the United States, of the Exercise 
Price payable with respect to the Securities being purchased. If the 
Warrantholder shall represent and warrant that all applicable registration 
and prospectus delivery requirements for their sale have been complied with 
upon sale of the Securities received upon exercise of the Warrant(s), such 
certificates shall not bear a legend with respect to the Act.

                                       4



     If fewer than all the Securities purchasable under the Warrant(s) are 
purchased, the Company will, upon such partial exercise, execute and deliver 
to the Warrantholder a new Warrant Certificate (dated the date hereof), in 
form and tenor similar to the Warrant Certificate, evidencing that portion of 
the Warrant not exercised. The Securities to be obtained on exercise of the 
Warrant(s) will be deemed to have been issued, and any person exercising the 
Warrants will be deemed to have become a holder of record of those Securities 
as of the date of the payment of the Exercise Price.
   
     (b)  In addition to the method of payment set forth in paragraph (a) of 
this Section 2 and in lieu of any cash payment required thereunder, the 
Warrantholder shall have the right at any time and from time to time to 
exercise the Warrant(s) in full or in part by surrendering the Warrant 
Certificate in the manner specified herein in exchange for the number of 
Units equal to the quotient derived from DIVIDING the NUMERATOR (which shall 
be an amount equal to the DIFFERENCE BETWEEN: (I) the number of Units or 
other Securities as to which the Warrant is being exercised MULTIPLIED by the 
per share Market Price of such Unit or other Securities, AND (II) the number 
of Units or other Securities as to which the Warrant is being exercised 
MULTIPLIED  by the Exercise Price) BY the DENOMINATOR which shall be the per 
share Market Price of such Unit or other Securities.  Solely for the purposes 
of this paragraph, Market Price shall be calculated either: (i) on the date 
on which the form of election attached hereto is deemed to have been sent to 
the Company pursuant to Section 10 hereof (Notice Date") or (ii) as the 
average of the Market Prices for each of the five trading days preceding the 
Notice Date, whichever of (i) or (ii) is greater.
    
     As used herein, the term "Market Price" at any date shall be deemed to be,
when referring to any Security, the last reported sale price, or, in case no
such reported sale takes place on such day, the average of the last reported
sale prices for the last three (3) trading days, in either case as officially
reported by the principal securities exchange on which such Security is listed
or admitted to trading or by the NASDAQ Stock Market ("NSM"), or, if such
Security is not listed or admitted to trading on any national securities
exchange or quoted by the National Association of Securities Dealers Automated
Quotation System ("NASDAQ"), the average closing bid price as furnished by the
National Association of Securities Dealers, Inc. ("NASD") through NASDAQ or
similar organization if NASDAQ is no longer reporting such information, or if
such Security is not quoted on NASDAQ, as determined in good faith (using
customary valuation methods) by resolution of the members of the Board of
Directors of the Company, based on the best information available to it.
   
     (c)  If at the time the Warrants are exercised there are no outstanding
shares of Series A Preferred Stock, the exercising Warrantholder shall receive
(upon payment of the Exercise Price), in lieu of Series A Preferred Stock, the
Securities or other property which such Warrantholder would have held had such
Warrantholder exercised such Warrants, obtained Series A Preferred Stock and
converted such Series A Preferred Stock on the last day on which shares of
outstanding Series A Preferred Stock were in existence and thereafter had
    
                                       5


   
continued to hold the Securities or other property so obtained and any 
Securities or other property thereafter issued in respect of any such 
Securities.

     (d)  If, at the time the Warrants are exercised there are no outstanding 
Underlying Warrants, the exercising Warrantholder shall receive (upon payment 
of the Exercise Price and the Underlying Warrant exercise price 
[prior to the termination date of the Underlying Warrant]), in lieu of 
Underlying Warrants, the Securities or other property which such 
Warrantholder would have held had such Warrantholder exercised such 
Underlying Warrants on the last day on which outstanding Underlying Warrants 
were in existence and thereafter had continued to hold the Securities or 
other property so obtained and any Securities or other property thereafter 
issued in respect of any such Securities.
    
     3.   ADJUSTMENTS IN CERTAIN EVENTS.   The number, class, and price of
Securities for which the Warrant Certificate may be exercised are subject to
adjustment from time to time upon the happening of certain events as follows:
   
     (a)  If the outstanding shares of the Company's Common Stock or Series A 
Preferred Stockare divided into a greater number of shares or a dividend in 
stock is paid on the Common Stock or Series A Preferred Stock, the number of 
the Securities for which the Warrant(s) is (are) then exercisable will be 
proportionately increased and the Exercise Price will be proportionately 
reduced; and, conversely, if the outstanding shares of Common Stock or Series 
A Preferred Stock are combined into a smaller number of shares of Common 
Stock or Series A Preferred Stock, the number of the Securities for which the 
Warrant(s) is (are) then exercisable will be proportionately reduced and the 
Exercise Price will be proportionately increased. The increases and 
reductions provided for in this paragraph (a) of Section 3 will be made with 
the intent and, as nearly as practicable, the effect that neither the 
percentage of the total equity of the Company obtainable on exercise of the 
Warrant(s) nor the price payable for such percentage upon such exercise will 
be affected by any event described in this paragraph (a) of Section 3.

     (b)  In case of any change in the Common Stock or Series A Preferred 
Stock through merger, consolidation, reclassification, reorganization, 
partial or complete liquidation, purchase of substantially all the assets of 
the Company, or other change in the capital structure of the Company, then, 
as a condition of such change, lawful and adequate provision will be made so 
that the holder of the Warrant Certificate will have the right thereafter to 
receive upon the exercise of the Warrant(s) the kind and amount of shares of 
stock or other securities or property which it would have been entitled if, 
immediately prior to such event, it had held the number of shares of Common 
Stock obtainable upon the exercise of the Warrant(s) and the Securities 
underlying the Warrants.  In any such case, appropriate adjustment will be 
made in the application of the provisions set forth herein with respect to 
the rights and interest thereafter of the Warrantholder, to the end that the 
provisions set forth herein will thereafter be applicable, as nearly as 
reasonably may be, in relation to any shares of stock or other property 
thereafter deliverable upon the exercise of the Warrant(s). The Company will 
not permit any change in its capital structure to occur unless the issuer of 
the shares of stock or 
    

                                       6



other securities to be received by the holder of the Warrant Certificate, if 
not the Company, agrees to be bound by and comply with the provisions of the 
Warrant Certificate.
   
     (c)  When any adjustment is required to be made in the number of Units 
or other Securities, or property purchasable upon exercise of the Warrant(s), 
the Company will promptly determine the new number of such Units or other 
Securities or property purchasable upon exercise of the Warrant(s) and (i) 
prepare and retain on file a statement describing in reasonable detail the 
method used in arriving at the new number of such Units or other Securities 
or property purchasable upon exercise of the Warrant(s) and (ii) cause a copy 
of such statement to be mailed to the Warrantholder within thirty (30) days 
after the date of the event giving rise to the adjustment.
    
     (d)  No fractional shares of Common Stock or other securities will be 
issued in connection with the exercise of the Warrant(s), but the Company 
will pay, in lieu of fractional shares, a cash payment therefor on the basis 
of the Market Price as that term is defined in paragraph (b) of Section 2.

     (e)  If preferred securities of the Company or securities of any 
subsidiary of the Company are distributed pro rata to holders of any or all 
of the Company's securities, such number of securities will be distributed to 
the Warrantholder or its assignee upon exercise of its rights hereunder as 
such Warrantholder or assignee would have been entitled to if the Warrant 
Certificate had been exercised prior to such distribution. The provisions 
with respect to adjustment of the Common Stock provided in this Section 3 
will also apply to the preferred securities and securities of any subsidiary 
to which the Warrantholder or his assignee is entitled under this paragraph 
(e) of Section 3.
   
     (f)  Notwithstanding anything herein to the contrary, there will be no 
adjustment made hereunder on account of the sale of the Securities 
purchasable upon exercise of the Warrant(s).

     (g)  Whenever the Exercise Price payable upon exercise of each Warrant 
is adjusted pursuant to subsections (a) or (b), the number of Units 
purchasable upon exercise of the Warrant shall simultaneously be adjusted by 
multiplying the number of Units initially issuable upon exercise of the 
Warrant by the Exercise Price in effect on the date hereof and dividing the 
product so obtained by the Exercise Price, as adjusted.
    
     4.   RESERVATION OF SHARES.   The Company agrees that the number of 
shares of Common Stock or other Securities sufficient to provide for the 
exercise of the Warrant(s) upon the basis set forth above will at all times 
during the term of the Warrant(s) be reserved for exercise.
   
     5.   VALIDITY OF SECURITIES.  All Securities delivered pursuant to the 
exercise of the Warrant(s), will be duly and validly issued in accordance 
with their terms, and the Company 
    
                                       7

   

will pay all documentary and transfer taxes, if any, in respect of the 
original issuance thereof upon exercise of the Underlying Warrant(s). 
    
 6.   REGISTRATION OF SECURITIES ISSUABLE ON EXERCISE OF WARRANT(S).

     (a)  The Company shall register the Securities with the Commission 
pursuant to the Act so as to allow the unrestricted sale of the Securities to 
the public from time to time during a five year period commencing on the 
first anniversary of the Effective Date and ending at 5:00 p.m. Pacific Time 
on the fifth anniversary of the Effective Date (the "Registration Period"). 
The Company shall also file such applications and other documents necessary 
to permit the sale of the Securities to the public during the Registration 
Period in those states in which the Shares were qualified for sale in the 
Offering or such other states as to which the Company and the Warrantholder 
agree.  In order to comply with the provisions of this Section 6(a), the 
Company shall not be required to file more than one registration statement. 
No registration right of any kind, "piggyback" or otherwise, is required to 
be in effect longer than five years from the Closing Date.
  
     (b)  The Company shall pay all of the Expenses relating to the 
registration, offer, and sale of the Securities.
  
     (c)  Except as specifically provided herein, the manner and conduct of 
the registration, including the contents of the registration statement, will 
be entirely in the control and at the discretion of the Company. The Company 
shall file such post-effective amendments and supplements as may be necessary 
to maintain the currency of the registration statement during the period of 
its use. In addition, if the Warrantholder participating in the registration 
is advised by counsel that the registration statement, in its opinion, is 
deficient in any material respect, the Company shall use its best efforts to 
cause the registration statement to be amended to eliminate the concerns 
raised.
  
     (d)  The Company shall furnish to the Warrantholder the number of copies 
of a prospectus, including a preliminary prospectus, in conformity with the 
requirements of the Act, and such other documents as the Warrantholder may 
reasonably request in order to facilitate the disposition of Securities owned 
by it.
  
     (e)  The Company shall, at the request of Warrantholder: (i) furnish an 
opinion of the counsel representing the Company for the purposes of the 
registration pursuant to this Section 6, addressed to the Warrantholder and 
any Participating Underwriter, (ii) furnish an appropriate letter from the 
independent public accountants of the Company, addressed to the Warrantholder 
and any Participating Underwriter, and (iii) make representations and 
warranties to the Warrantholder and any Participating Underwriter. A request 
pursuant to this subsection (e) may be made on three occasions. The documents 
required to be delivered pursuant to this subsection (e) will be dated within 
30 days of the request and will be, in form and substance equivalent to 
similar documents furnished to the underwriters in connection with the 
Offering, with such changes as may be appropriate in light of changed 
circumstances.

                                       8



     7.   INDEMNIFICATION IN CONNECTION WITH REGISTRATION.

     (a)  In connection with its registration obligations, the Company shall 
indemnify and hold harmless the selling Warrantholder, any person who 
controls the selling Warrantholder within the meaning of the Act, and any 
Participating Underwriter against any losses, claims, damages, or 
liabilities, joint or several, to which the Warrantholder, controlling 
person, or Participating Underwriter may be subject under the Act or 
otherwise; and it shall reimburse each Warrantholder, each controlling 
person, and each Participating Underwriter for any legal or other expenses 
reasonably incurred by the Warrantholder, controlling person, or 
Participating Underwriter in connection with investigating or defending any 
such loss, claim, damage, liability, or action, insofar as such losses, 
claims, damages, or liabilities, joint or several (or actions in respect 
thereof), arise out of or are based upon any untrue statement or alleged 
untrue statement of any material fact contained, on the effective date 
thereof, in any such registration statement or any preliminary prospectus or 
final prospectus, or any amendment or supplement thereto, or arise out of or 
are based upon 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; PROVIDED, HOWEVER, that the Company will not be 
liable in any case to the extent that any loss, claim, damage, or liability 
arises out of or is based upon any untrue statement or alleged untrue 
statement or omission or alleged omission made in any registration statement, 
preliminary prospectus, final prospectus, or any amendment or supplement 
thereto, in reliance upon and in conformity with written information 
furnished by the Warrantholder or any person controlling the Warrantholder or 
any Participating Underwriter for use in the preparation thereof. The 
indemnity agreement contained in this subparagraph (a) will not apply to 
amounts paid to any claimant in settlement of any suit or claim unless such 
payment is first approved by the Company, such approval not to be 
unreasonably withheld or delayed.
  
     (b)  The selling Warrantholder, as a condition of the Company's 
registration obligation, shall indemnify and hold harmless the Company, each 
of its directors, each of its officers who have signed any registration 
statement or other filing or any amendment or supplement thereto, and any 
person who controls the Company within the meaning of the Act, against any 
losses, claims, damages, or liabilities to which the Company or any such 
director, officer, or controlling person may become subject under the Act or 
otherwise, and shall reimburse any legal or other expenses reasonably 
incurred by the Company or any such director, officer, or controlling person 
in connection with investigating or defending any such loss, claim, damage, 
liability, or action, insofar as such losses, claims, damages, or liabilities 
(or actions in respect thereof) arise out of or are based upon any untrue or 
alleged untrue statement of any material fact contained in said registration 
statement, any preliminary or final prospectus, or other filing, or any 
amendment or supplement thereto, or arise out of or are based upon the 
omission or the alleged omission to state therein a material fact required to 
be stated therein or necessary to make the statements therein not misleading, 
but only to the extent that such untrue statement or alleged untrue statement 
or omission or alleged omission was made in said registration statement, 
preliminary or final prospectus, or other filing, or 

                                       9



amendment or supplement, in reliance upon and in conformity with written 
information furnished by the Warrantholder or any person controlling the 
Warrantholder or any Participating Underwriter for use in the preparation 
thereof; PROVIDED, HOWEVER, that the indemnity agreement contained in this 
subparagraph (b) shall not apply to amounts paid to any claimant in 
settlement of any suit or claim unless such payment is first approved by the 
Warrantholder, such approval not to be unreasonably withheld or delayed.

     (c)  Promptly after receipt by an indemnified party under subparagraphs 
(a) or (b) above of notice of the commencement of any action, such 
indemnified party will, if a claim in respect thereof is to be made against 
an indemnifying party, notify the indemnifying party of the commencement 
thereof, but the omission to notify the indemnifying party will not relieve 
it from any liability that it may have to any indemnified party otherwise 
than under subparagraphs (a) and (b).
  
     (d)  If any such action is brought against any indemnified party and it 
notifies an indemnifying party of the commencement thereof, the indemnifying 
party will be entitled to participate in, and, to the extent that it may 
wish, jointly with any other indemnifying party similarly notified, to assume 
the defense thereof, with counsel satisfactory to such indemnified parry; and 
after notice from the indemnifying party to such indemnified party of its 
election to assume the defense thereof, the indemnifying party will not be 
liable to such indemnified party for any legal or other expenses subsequently 
incurred by such indemnified party in connection with the defense thereof 
other than reasonable costs of investigation.

     8.   RESTRICTIONS ON TRANSFER.  The Warrant Certificate and the 
Warrant(s) may not be sold, transferred, assigned or hypothecated except to 
underwriters of the Offering or to individuals who are either a partner or an 
officer of such an underwriter or by will or by operation of law.  The 
Warrant(s) may only be exercised by one of the aforesaid persons or by a 
successor entity or legal representative.  The Warrant(s) may be divided or 
combined, upon request to the Company by the Warrantholder, into a 
certificate or certificates evidencing the same aggregate number of Warrants.

     9.   NO RIGHTS AS A STOCKHOLDER.  Except as otherwise provided herein, 
the Warrantholder will not, by virtue of ownership  of the Warrant(s), be 
entitled to any rights of a stockholder of the Company but will, upon written 
request to the Company, be entitled to receive such quarterly or annual

     Each Unit consists of one share of the Company's Series A Preferred 
Stock, par value $.004 per share (the "Series A Preferred Stock") and two 
common stock purchase warrants (the "Underlying Warrants").  The Series A 
Preferred Stock is convertible into four shares of the Company's common

certain circumstances ("Conversion Ratio") at any time at the option of the 
holder.  Each share of Preferred Stock shall automatically convert into four

four-tenths of one share of Common Stock every six months commencing the date 
of this Prospectus.  Such Common Stock dividends shall be issued and 
distributed within 30 days following their accrual every six months. Each 
Underlying Warrant entitles holder to purchase one share of Common Stock at a 
price of $_____ per share ("Warrant Exercise Price"), subject to adjustment 
under certain circumstances.  The Warrants are exercisable commencing on the 
date of issue and will expire on January __, 2003 (the "Warrant Expiration

     The Warrant Agreement provides that upon the occurrence of certain 
events the Exercise Price and the type and/or number of the Company's 
securities issuable upon exercise of the Warrant(s) or securities issuable 
upon conversion or exercise of such securities may, subject to certain 
conditions, be adjusted. In such event, the Company will, at the request of 
the holder, issue a new Warrant Certificate evidencing the adjustment in the 
Exercise Price and the number and/or type of securities issuable upon the 
exercise of the Warrant(s) or securities issuable upon conversion or exercise 
of such securities; PROVIDED, HOWEVER, that the failure of the Company to 
issue such new Warrant Certificate shall not in any way change, alter, or 
otherwise impair, the rights of the holder as set forth in the Warrant 
Agreement.

     Upon due presentment for registration of transfer of this Warrant 
Certificate at an office or agency of the Company, a new Warrant Certificate 
or Warrant Certificates of like tenor and evidencing a like number of 
securities for which this Warrant may be exercised shall 

                                       A-2

subject to the limitations provided herein and in the Warrant Agreement, 
without any charge except for any tax or other governmental charge imposed in 
connection with such transfer.

     Upon the exercise of less than all of the securities for which this 
Warrant may be exercised, the Company shall forthwith issue to the holder 
hereof a new Warrant Certificate representing the remaining number of 
unexercised Warrants.

     The Company may deem and treat the registered holder(s) hereof 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, and 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.

     All terms use in this Warrant Certificate which are defined in the 
Warrant Agreement shall have the meanings assigned to them in the Warrant 
Agreement.

          IN WITNESS WHEREOF, the Company has caused this Warrant Certificate 
to be duly executed under its corporate seal.
