                      IN VERITAS MEDICAL DIAGNOSTICS, INC.

                                  UNIT WARRANT

Warrant No. A-1                                                       ___ shares

                              Original Issue Date:

     THIS CERTIFIES THAT, FOR VALUE RECEIVED, [ ] or its registered assigns
("Holder") is entitled to purchase, on the terms and conditions hereinafter set
forth, at any time or from time to time from the date hereof until 5:00 p.m.,
Eastern Time, on the one hundred eightieth day from the effective date of the
registration statement filed in connection with the offering by the Company
pursuant to the Private Placement Memorandum, dated March 23, 2005, (the
"Warrant Period"), or if such date is not a day on which the Company (as
hereinafter defined) is open for business, then the next succeeding day on which
the Company is open for business (such date is the "Expiration Date"), but not
thereafter, to purchase up to ________________ (_________) units (the "Units").
Each unit consists of one share of 5% convertible preferred stock (the
"Preferred Stock") of In Veritas Medical Diagnostics, Inc., a Colorado
corporation (the "Company"), $.001 par value, and one warrant to purchase one
share of common stock, and is exercisable at $0.65 per Unit (the "Exercise
Price"), such number of shares and Exercise Price being subject to adjustment
upon the occurrence of the contingencies set forth in this Warrant.

     Section 1. Exercise of Warrant; Conversion of Warrant.

          (a) This Warrant may, at the option of Holder, be exercised in whole
     or in part from time to time by delivery to the Company at its principal
     office, Attention: President, on or before 5:00 p.m., Eastern Time, on the
     Expiration Date, (i) a written notice of such Holder's election to exercise
     this Warrant (the "Exercise Notice"), which notice may be in the form of
     the Notice of Exercise attached hereto, properly executed and completed by
     Holder or an authorized officer thereof, (ii) a check payable to the order
     of the Company, in an amount equal to the product of the Exercise Price
     multiplied by the number of Units specified in the Exercise Notice, and
     (iii) this Warrant (the items specified in (i), (ii), and (iii) are
     collectively the "Exercise Materials").

          (b) As promptly as practicable, and in any event within five (5)
     business days after its receipt of the Exercise Materials, Company shall
     execute or cause to be executed and delivered to Holder a certificate or
     certificates representing the number of Units specified in the Exercise
     Notice, together with

<PAGE>

     cash in lieu of any fraction of a share, and if this Warrant is partially
     exercised, a new warrant on the same terms for the unexercised balance of
     the Units. The stock certificate or certificates shall be registered in the
     name of Holder or such other name or names as shall be designated in the
     Exercise Notice. The date on which the Warrant shall be deemed to have been
     exercised (the "Effective Date"), and the date the person in whose name any
     certificate evidencing the securities issued upon the exercise hereof is
     issued shall be deemed to have become the holder of record of such shares,
     shall be the date the Company receives the Exercise Materials, irrespective
     of the date of delivery of a certificate or certificates evidencing the
     securities issued upon the exercise or conversion hereof, provided,
     however, that if the Exercise Materials are received by the Company on a
     date on which the stock transfer books of the Company are closed, the
     Effective Date shall be the next succeeding date on which the stock
     transfer books are open. All securities issued upon the exercise or
     conversion of this Warrant will, upon issuance, be fully paid and
     nonassessable and free from all taxes, liens, and charges with respect
     thereto.

     Section 2. Adjustments to Units. The number of Units issuable upon the
exercise hereof shall be subject to adjustment as follows:

          (a) In the event the Company is a party to a consolidation, share
     exchange, or merger, or the sale of all or substantially all of the assets
     of the Company to, any person, or in the case of any consolidation or
     merger of another corporation into the Company in which the Company is the
     surviving corporation, and in which there is a reclassification or change
     of the securities of the Company, this Warrant shall after such
     consolidation, share exchange, merger, or sale be exercisable for the kind
     and number of securities or amount and kind of property of the Company or
     the corporation or other entity resulting from such share exchange, merger,
     or consolidation, or to which such sale shall be made, as the case may be
     (the "Successor Company"), to which a holder of the number of Units
     deliverable upon the exercise (immediately prior to the time of such
     consolidation, share exchange, merger, or sale) of this Warrant would have
     been entitled upon such consolidation, share exchange, merger, or sale; and
     in any such case appropriate adjustments shall be made in the application
     of the provisions set forth herein with respect to the rights and interests
     of Holder, such that the provisions set forth herein shall thereafter
     correspondingly be made applicable, as nearly as may reasonably be, in
     relation to the number and kind of securities or the type and amount of
     property thereafter deliverable upon the exercise of this Warrant. The
     above provisions shall similarly apply to successive consolidations, share
     exchanges, mergers, and sales. Any adjustment required by this Section 2
     (a) because of a consolidation, share exchange, merger, or sale shall be
     set forth in an undertaking delivered to Holder and executed by the
     Successor Company which provides that Holder shall have the right to
     exercise this Warrant for the kind and number of securities or amount and
     kind of property of the Successor Company or to which the holder of a
     number of Units deliverable upon exercise (immediately prior to the time of
     such consolidation, share exchange, merger, or sale) of this Warrant would
     have been entitled upon such consolidation, share exchange, merger, or
     sale. Such undertaking shall also provide for future adjustments to the
     number of Units and the Exercise Price in accordance with the provisions
     set forth in Section 2 hereof.

          (b) In the event the Company should at any time, or from time to time
     after the Original Issue Date, fix a record date for the effectuation of a
     stock split or subdivision of the outstanding securities of the Company or
     the determination of holders of securities entitled to receive a dividend
     or other distribution payable in additional securities or rights
     convertible into, or entitling the holder thereof to receive directly or
     indirectly, additional securities (hereinafter referred to as " Securities
     Equivalents") without payment of any consideration by such holder for the

                                        2
<PAGE>

     additional securities or Securities Equivalents (including the additional
     securities issuable upon conversion or exercise thereof), then, as of such
     record date (or the date of such dividend, distribution, split, or
     subdivision if no record date is fixed), the number of Units issuable upon
     the exercise hereof shall be proportionately increased and the Exercise
     Price shall be appropriately decreased by the same proportion as the
     increase in the number of outstanding Securities Equivalents resulting from
     the dividend, distribution, split, or subdivision. Notwithstanding the
     preceding sentence, no adjustment shall be made to decrease the Exercise
     Price below $.001 per Share.

          (c) In the event the Company should at any time or from time to time
     after the Original Issue Date, fix a record date for the effectuation of a
     reverse stock split, or a transaction having a similar effect on the number
     of outstanding securities of the Company, then, as of such record date (or
     the date of such reverse stock split or similar transaction if no record
     date is fixed), the number of Units issuable upon the exercise hereof shall
     be proportionately decreased and the Exercise Price shall be appropriately
     increased by the same proportion as the decrease of the number of
     outstanding Securities Equivalents resulting from the reverse stock split
     or similar transaction.

          (d) In the event the Company should at any time or from time to time
     after the Original Issue Date, fix a record date for a reclassification of
     its common stock or other securities, then, as of such record date (or the
     date of the reclassification if no record date is set), this Warrant shall
     thereafter be convertible into such number and kind of securities as would
     have been issuable as the result of such reclassification to a holder of a
     number of shares of common stock or other securities equal to the number of
     Units issuable upon exercise of this Warrant immediately prior to such
     reclassification, and the Exercise Price shall be unchanged.

          (e) Until the Expiration Date, if the Company shall issue any Common
     Stock except for the (except for (i) any issuances pursuant to the 2005
     Stock Incentive Plan and (ii) any issuances of capital stock by the Company
     valued at less than $100,000, for a consideration less than the Stated
     Value), prior to the complete exercise of this Warrant for a consideration
     less than the Exercise Price that would be in effect at the time of such
     issue, then, and thereafter successively upon each such issue, the Exercise
     Price shall automatically and with no action required by the Company or
     Holder, be reduced to such other lower issue price. For purposes of this
     adjustment, the issuance of any security or debt instrument of the Company
     carrying the right to convert such security or debt instrument into Common
     Stock or of any warrant, right or option to purchase Common Stock shall
     result in an adjustment to the Exercise Price upon the issuance of the
     above-described security, debt instrument, warrant, right, or option and
     again at any time upon any subsequent issuances of shares of Common Stock
     upon exercise of such conversion or purchase rights if such issuance is at
     a price lower than the Exercise Price in effect upon such issuance.

          (f) The Company will not, by amendment of its Certificate of
     Incorporation or through reorganization, consolidation, merger,
     dissolution, issue, or sale of securities, sale of assets or any other
     voluntary action, void or seek to avoid the observance or performance of
     any of the terms of the Warrant, but will at all times in good faith assist
     in the carrying out of all such terms and in the taking of all such actions
     as may be necessary or appropriate in order to protect the rights of Holder
     against dilution or other impairment. Without limiting the generality of
     the foregoing, the Company (x) will not create a par value of any share of
     stock receivable upon the exercise of the Warrant above the amount payable
     therefor upon such exercise, and (y) will take all such action as may be
     necessary or appropriate in order that the Company may validly and legally
     issue fully paid and non-assessable securities upon the exercise of the
     Warrant.

                                        3
<PAGE>

          (g) When any adjustment is required to be made in the number or kind
     of securities purchasable upon exercise of the Warrant, or in the Exercise
     Price, the Company shall promptly notify Holder of such event and of the
     number of securities or property thereafter purchasable upon exercise of
     the Warrants and of the Exercise Price, together with the computation
     resulting in such adjustment.

          (h) The Company covenants and agrees that all securities which may be
     issued will, upon issuance, be validly issued, fully paid, and
     non-assessable. The Company further covenants and agrees that the Company
     will at all times have authorized and reserved, free from preemptive
     rights, a sufficient number of securities to provide for the exercise of
     the Warrant in full.

     Section 3. No Stockholder Rights. This Warrant shall not entitle Holder
hereof to any voting rights or other rights as a stockholder of the Company.

     Section 4. Transfer of Securities.

          (a) This Warrant and the Units and any shares of capital stock
     received in respect thereof, whether by reason of a stock split or share
     reclassification thereof, a stock dividend thereon, or otherwise, shall not
     be transferable except upon compliance with the provisions of the
     Securities Act of 1933, as amended (the "Securities Act") and applicable
     state securities laws with respect to the transfer of such securities. The
     Holder, by acceptance of this Warrant, agrees to be bound by the provisions
     of Section 4 hereof and to indemnify and hold harmless the Company against
     any loss or liability arising from the disposition of this Warrant or the
     securities issuable upon exercise hereof or any interest in either thereof
     in violation of the provisions of this Warrant.

          (b) Each certificate for the Units and any shares of capital stock
     received in respect thereof, whether by reason of a stock split or share
     reclassification thereof, a stock dividend thereon or otherwise, and each
     certificate for any such securities issued to subsequent transferees of any
     such certificate shall (unless otherwise permitted by the provisions
     hereof) be stamped or otherwise imprinted with a legend in substantially
     the following form:

          "NEITHER THIS WARRANT NOR THE SECURITIES ISSUABLE UPON EXERCISE HEREOF
          HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
          ANY APPLICABLE STATE SECURITIES LAW AND NEITHER MAY BE SOLD OR
          OTHERWISE TRANSFERRED UNTIL (I) A REGISTRATION STATEMENT UNDER SUCH
          SECURITIES ACT AND SUCH APPLICABLE STATE SECURITIES LAWS SHALL HAVE
          BECOME EFFECTIVE WITH REGARD THERETO, OR (II) THE COMPANY SHALL HAVE
          RECEIVED A WRITTEN OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY TO THE
          EFFECT THAT REGISTRATION UNDER SUCH SECURITIES ACT AND SUCH APPLICABLE
          STATE SECURITIES LAWS IS NOT REQUIRED IN CONNECTION WITH SUCH PROPOSED
          TRANSFER."

     Section 5. Registration.

     All Units are subject to the rights and privileges granted to the
participants in the private placement offering pursuant to which this Warrant
was issued.

     part, at the sole option of the Company in the event that the average
     closing price for the Company's common stock for any five trading day
     period during the Warrant Period, is greater than $.78.

          (b) If this Warrant is redeemed in part pursuant to this Section 6,
     the Company, in its sole discretion, shall use such method as it deems fair
     and appropriate to determine the part of this Warrant to be so redeemed.

     Section 7. Miscellaneous.

     Warrant, properly endorsed, to the Company. The Company may deem and treat
     the registered holder of this Warrant at any time as the absolute owner
     hereof for all purposes and shall not be affected by any notice to the
     contrary.

          (c) Notwithstanding any provision herein to the contrary, Holder may
     not exercise, sell, transfer, or otherwise assign this Warrant unless the
     Company is provided with an opinion of counsel satisfactory in form and
     substance to the Company, to the effect that such exercise, sale, transfer,
     or assignment would not violate the Securities Act or applicable state
     securities laws.

          (d) This Warrant may be divided into separate warrants covering one
     Unit or any whole multiple thereof, for the total number of Units then
     subject to this Warrant at any time, or from time to time, upon the request

     form and tenor as this Warrant, except for any requested change in the name

     underlying the Warrant Units, the common stock to be issued upon conversion
     of the Shares underlying the Over Allotment Units and the common stock
     underlying the Warrants underlying the Over Allotment Shares (referred to
     as the "Registrable Securities").

          (b) Effectiveness of the Registration Statement. The Company shall use
     its reasonable best efforts to have the Registration Statement declared
     effective by the SEC by no later than one hundred and twenty (120) days
     after the earlier of (i) the closing of the offering or (ii) the
     termination date, and to insure that the Registration Statement remains in
     effect for the period specified in Section 3(a), subject to the terms and
     conditions of this Agreement.

          (c) Failure to File or Obtain Effectiveness of Registration
     Statements. In the event the Company fails for any reason to file or to
     obtain the effectiveness of a Registration Statement within the time
     periods set forth in Sections 1(a) and 1(b), then the Company will make pro
     rata payments to the Holder, as liquidated damages and not as a penalty, in
     an amount equal to 2.0% of the aggregate amount invested by the Holder for
     each 30-day period or pro rata for any portion thereof following the date
     by which such Registration Statement should have been filed or decaled
     effective. Such payments shall be in partial compensation to the Holder,
     and shall not constitute the Holder's exclusive remedy for such events.
     Such payments shall be made to each Investor in cash.

          (d) The parties hereto acknowledge and agree that the sums payable
     under Sections 1(c) or 1(d) above shall constitute liquidated damages and
     not penalties. The parties further acknowledge that (a) the amount of loss
     or damages likely to be incurred is incapable or is difficult to precisely
     estimate, (b) the amounts specified in such Sections bear a reasonable
     proportion and are not plainly or grossly disproportionate to the probable
     loss likely to be incurred in connection with any failure by the Company to
     obtain or maintain the effectiveness of a Registration Statement, (c) one
     of the reasons for the parties reaching an agreement as to such amounts was
     the uncertainty and cost of litigation regarding the question of actual
     damages, and (d) the parties are sophisticated business parties and have
     been represented by sophisticated and able legal and financial counsel and
     negotiated this Agreement at arm's length.

     2. Cooperation with Company. The Holder will cooperate with the Company in
all respects in connection with this Agreement, including, timely supplying all
information reasonably requested by the Company and executing and returning all
documents reasonably requested in connection with the registration and sale of
the Registrable Securities.

     3. Registration Procedures. If and whenever the Company is required by any
of the provisions of this Agreement to use its best efforts to effect the
registration of any of the Registrable Securities under the 1933 Act, the
Company shall (except as otherwise provided in this Agreement), as expeditiously
as possible:

          a. prepare and file with the Securities and Exchange Commission (the
     "Commission") a registration statement and shall use its best efforts to
     cause such registration statement to become effective and remain effective

                                        2
<PAGE>

     until earlier of (i) two years from the date of issuance of the Warrants,
     (ii) the date that none of the Registrable Securities are or may become
     issued and outstanding, (iii) the date that all of the Registrable
     Securities have been sold, (iv) the date the investors in the Offering
     receive an opinion of counsel to the Company, which counsel shall be
     reasonably acceptable to the investors in the Offering, that the securities
     may be sold under the provisions of Rule 144 without limitation as to
     volume, or (v) all Registrable Securities have been otherwise transferred
     to persons who may trade such shares without restriction under the Act, and
     the Company has delivered a new certificate or other evidence of ownership
     for such securities not bearing a restrictive legend.

          b. prepare and file with the Commission such amendments and
     supplements to such registration statement and the prospectus used in
     connection therewith as may be necessary to keep such registration
     statement effective and to comply with the provisions of the 1933 Act with
     respect to the sale or other disposition of all securities covered by such
     registration statement whenever the Holder of such securities shall desire
     to sell or otherwise dispose of the same (including prospectus supplements
     with respect to the sales of securities from time to time in connection
     with a registration statement pursuant to Rule 415 of the Commission);

          c. furnish to the Holder such numbers of copies of a summary
     prospectus or other prospectus, including a preliminary prospectus or any
     amendment or supplement to any prospectus, in conformity with the
     requirements of the 1933 Act, and such other documents, as such Holder may
     reasonably request in order to facilitate the public sale or other
     disposition of the securities owned by such 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 each Holder shall reasonably request, and do any
     and all other acts and things which may be necessary or advisable to enable
     such Holder to consummate the public sale or other disposition in such
     jurisdiction of the securities owned by such Holder, except that the
     Company shall not for any such purpose be required to qualify to do
     business as a foreign corporation in any jurisdiction wherein it is not so
     qualified or to file therein any general consent to service of process;

          e. use its best efforts to list such securities on any securities
     exchange on which any securities of the Company is then listed, if the
     listing of such securities is then permitted under the rules of such
     exchange;

          f. enter into and perform its obligations under an underwriting
     agreement, if the offering is an underwritten offering, in usual and
     customary form, with the managing underwriter or underwriters of such
     underwritten offering;

                                        3
<PAGE>

          g. notify the Holder of Registrable Securities covered by such
     registration statement, at any time when a prospectus relating thereto
     covered by such registration statement is required to be delivered under
     the 1933 Act, of the happening of any event of which it has knowledge 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
     then existing; and

          h. furnish, at the request of the Holder on the date such Registrable
     Securities are delivered to the underwriters for sale pursuant to such
     registration or, if such Registrable Securities are not being sold through
     underwriters, on the date the registration statement with respect to such
     Registrable Securities becomes effective, (i) an opinion, dated such date,
     of the counsel representing the Company for the purpose of such
     registration, addressed to the underwriters, if any, and to the Holder
     making such request, covering such legal matters with respect to the
     registration in respect of which such opinion is being given as the Holder
     of such Registrable Securities may reasonably request and are customarily
     included in such an opinion and (ii) letters, dated, respectively, (1) the
     effective date of the registration statement and (2) the date such
     Registrable Securities are delivered to the underwriters, if any, for sale
     pursuant to such registration from a firm of independent certified public
     accountants of recognized standing selected by the Company, addressed to
     the underwriters, if any, and to the Holder making such request, covering
     such financial, statistical and accounting matters with respect to the
     registration in respect of which such letters are being given as the Holder
     of such Registrable Securities may reasonably request and are customarily
     included in such letters.

     4. Expenses. All expenses incurred in any registration of the Holder's
Registrable Securities under this Agreement shall be paid by the Company,
including, without limitation, printing expenses, fees and disbursements of
counsel for the Company, expenses of any audits to which the Company shall agree
or which shall be necessary to comply with governmental requirements in
connection with any such registration, all registration and filing fees for the
Holder's Registrable Securities under federal and State securities laws, and
expenses of complying with the securities or blue sky laws of any jurisdictions;
provided, however, the Company shall not be liable for (a) any discounts or
commissions to any underwriter; (b) any stock transfer taxes incurred with
respect to Registrable Securities sold in the Offering or (c) the fees and
expenses of counsel for any Holder, provided that the Company will pay the costs
and expenses of Company counsel when the Company's counsel is representing any
or all selling security holders.

     5. Indemnification. In the event any Registrable Securities are included in
a registration statement pursuant to this Agreement:

          a. Company Indemnity. Without limitation of any other indemnity
     provided to the Holder, either in connection with the Offering or
     otherwise, to the extent permitted by law, the Company shall indemnify and
     hold harmless the Holder, the affiliates, officers, directors and partners
     of each Holder, any underwriter (as defined in the 1933 Act) for such
     Holder, and each person, if any, who controls such Holder or underwriter
     (within the meaning of the 1933 Act or the Securities Exchange Act of 1934
     (the "Exchange Act"), against any losses, claims, damages or liabilities
     (joint or several) to which they may become subject under the 1933 Act, the
     Exchange 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

                                        4
<PAGE>

     (collectively a "Violation"): (i) any 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 alleged omission to state
     therein a material fact required to be stated therein, or necessary to make
     the statements therein, (iii) any violation or alleged violation by the
     Company of the 1933 Act, the Exchange Act, or (iv) any state securities law
     or any rule or regulation promulgated under the 1933 Act, the Exchange Act
     or any state securities law, and the Company shall reimburse each such
     Holder, affiliate, officer or director or partner, underwriter or
     controlling person for any legal or other expenses incurred by them in
     connection with investigating or defending any such loss, claim, damage,
     liability or action; provided, however, that the Company shall not be
     liable to the Holder 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 any such Holder or any other officer, director or
     controlling person thereof.

          b. Holder Indemnity. The Holder shall indemnify and hold harmless the
     Company, its affiliates, its counsel, officers, directors and
     representatives, any underwriter (as defined in the 1933 Act) and each
     person, if any, who controls the Company or the underwriter (within the
     meaning of the 1933 Act or liabilities (joint or several) to which they may
     become subject under the 1933 Act, the Exchange Act or any state securities
     law, and the Company shall reimburse each such Holder, affiliate, officer
     or director or partner, underwriter or controlling person for any legal or
     other expenses incurred by them in connection with investigating or
     defending any loss, claim, damage, liability or action; insofar as such
     losses, claims, damages or liabilities (or actions and respect thereof)
     arise out of or are based upon any statements or information provided by
     such Holder to the Company in connection with the offer or sale of
     Registrable Securities.

          c. Notice; Right to Defend. Promptly after receipt by an indemnified
     party under this Section 5 of notice of the commencement of any action
     (including any governmental action), such indemnified party shall, if a
     claim in respect thereof is to be made against any indemnifying party under
     this Section 5 deliver to the indemnifying party a written notice of the
     commencement thereof and the indemnifying party shall have the right to
     participate in and if the indemnifying party agrees in writing that it will
     be responsible for any costs, expenses, judgments, damages and losses
     incurred by the indemnified party with respect to such claim, 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 the indemnified party reasonably believes that 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 shall
     relieve such indemnifying party of any liability to the indemnified party

                                        5
<PAGE>

     under this Agreement only if and to the extent that such failure is
     prejudicial to its ability to defend such action, and 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 Agreement.

          d. Contribution. If the indemnification provided for in this Agreement
     is held by a court of competent jurisdiction to be unavailable to an
     indemnified party with respect to any loss, liability, claim, damage or
     expense referred to therein, then the indemnifying party, in lieu of
     indemnifying such indemnified party thereunder, shall contribute to the
     amount paid or payable by such indemnified party as a result of such loss,
     liability, claim, damage or expense in such proportion as is appropriate to
     reflect the indemnified party on the other hand in connection with the
     statements or omissions which resulted in such loss, liability, claim,
     damage or expense as well as any other relevant equitable considerations.
     The relevant fault of the indemnifying party and the indemnified party
     shall be determined by reference to, among other things, whether the untrue
     or alleged untrue statement of a material fact or the omission to state a
     material fact relates to information supplied by the indemnifying party or
     by the indemnified party and the parties' relative intent, knowledge,
     access to information and opportunity to correct or prevent such statement
     or omission. Notwithstanding the foregoing, the amount the Holder shall be
     obligated to contribute pursuant to the Agreement shall be limited to an
     amount equal to the proceeds to such Holder of the Registrable Securities
     sold pursuant to the registration statement which gives rise to such
     obligation to contribute (less the aggregate amount of any damages which
     the Holder has otherwise been required to pay in respect of such loss,
     claim, damage, liability or action or any substantially similar loss,
     claim, damage, liability or action arising from the sale of such
     Registrable Securities).

          e. Survival of Indemnity. The indemnification provided by this
     Agreement shall be a continuing right to indemnification and shall survive
     the registration and sale of any Registrable Securities by any person
     entitled to indemnification hereunder and the expiration or termination of
     this Agreement.

     6. Remedies.

          a. Time is of Essence. The Company agrees that time is of the essence
     of each of the covenants contained herein and that, in the event of a
     dispute hereunder, this Agreement is to be interpreted and construed in a
     manner that will enable the Holders to sell their Registrable Securities as
     quickly as possible after such Holders have indicated to the Company that
     they desire their Registrable Securities to be registered. Any delay on the
     part of the Company not expressly permitted under this Agreement, whether
     material or not, shall be deemed a material breach of this Agreement.

          b. Remedies Upon Default or Delay. The Company acknowledges the breach
     of any part of this Agreement may cause irreparable harm to a Holder and
     that monetary damages alone may be inadequate. The Company therefore agrees
     that the Holder shall be entitled to injunctive relief or such other
     applicable remedy as a court of competent jurisdiction may provide. Nothing
     contained herein will be construed to limit a Holder's right to any
     remedies at law, including recovery of damages for breach of any part of
     this Agreement.

                                        6

     telegraphed or telexed shall be deemed to be given when transmitted, or

     8. Successors and Assigns. Except as otherwise expressly provided herein,

and permitted assigns of the Company and each of the Holders.

     9. Amendment and Waiver. This Agreement may be amended, and the observance
of any term of this Agreement may be waived, but only with the written consent
of the Company and the Holder. No delay on the part of any party in the exercise
of any right, power or remedy shall operate as a waiver thereof, nor shall any
single or partial exercise by any party of any right, power or remedy preclude
any other or further exercise thereof, or the exercise of any other right, power
or remedy.

     10. Counterparts. One or more counterparts of this Agreement may be signed
by the parties, each of which shall be an original but all of which together

becomes invalid, illegal or unenforceable in any respect, the validity, legality
and enforceability of the remaining provisions contained herein shall not be
affected there.

     13. Headings. The headings in this Agreement are for convenience of
reference only and shall not be deemed to alter or affect the meaning or
interpretation of any provisions hereof.
