V-ONE Corporation
20250 Century Boulevard - Suite 300
Germantown, Maryland 20874

Gentlemen:

      1.  PURCHASE AND SALE.  V-ONE  Corporation,  a Delaware  corporation  (the
"COMPANY"),   has  offered  for  sale,  and  the   undersigned   purchaser  (the
"PURCHASER")  hereby tenders this  subscription  and applies for the purchase of
such number of shares  ("SHARES")  of common  stock,  $0.001 par value per share
(the "COMMON  STOCK") as can be purchased  with the  undersigned's  subscription
amount of  $______  at the  prevailing  closing  bid price for the Shares on the
Nasdaq  National  Market on the day of the Closing of this placement (as defined
below), but in no event less than $1.625 per Share (the "OFFERING  PRICE").  The
Offering is expected to expire on October 26, 1998 (seventeen (17) days from the
date of the Memorandum (as previously defined)),  subject to extension(s) by the
mutual agreement of the Company and LaSalle St. Securities, Inc. (the "PLACEMENT
AGENT") until  November 20, 1998 without  notice to investors  (the  "EXPIRATION
DATE"). The Offering is conditioned upon the Company's receipt and acceptance of
subscriptions  for a  minimum  of  $3,600,000  in gross  sale  proceeds  and the
Company's  receipt  of such  amount by the  Expiration  Date.  The  Company  has
reserved the right to raise an  additional  $2,400,000 in gross sale proceeds on
the same terms set forth above in the event this Offering is oversubscribed (the
"OVER  SUBSCRIPTION  OPTION").  The  Purchaser  must  subscribe for a minimum of
$100,000  of  Shares,  which  requirement  may be waived in the  Company's  sole
discretion.   Together  with  this  Subscription  Agreement,  the  Purchaser  is
delivering  to the  Company  the full  subscription  amount for the Shares  (the
"PURCHASE  PRICE")  subscribed  for.  This  subscription  may be rejected by the
Company  in its  sole  discretion  in whole or in  part.  THE  SIGNATURE  OF THE
UNDERSIGNED ON THE SIGNATURE PAGE CONSTITUTES THE EXECUTION OF THIS SUBSCRIPTION
AGREEMENT.

      2.  AMOUNT AND METHOD OF PAYMENT. Payment of the Purchase Price  required
to purchase the Shares  subscribed  for hereunder is being made by check payable
to  "LaSalle  National  Bank as  Escrow  Agent for  V-ONE  Corporation"  or wire
transfer in the amount of the Purchase Price for the undersigned's  subscription
to such account at the Escrow Agent (as previously  defined),  which  represents
payment  in full for the  subscribed  Shares.  If  payment is to be made by wire
transfer,  the Purchaser shall contact the Placement Agent to obtain appropriate
wire transfer instructions. If a subscription is rejected in whole or in part or
if the Offering is terminated for any reason, the Purchaser's subscription shall
be void and all funds  received from the Purchaser  shall be returned as soon as
practicable to the Purchaser without any interest thereon, and without charge or
deduction.

      3.  REPRESENTATIONS  AND  WARRANTIES OF PURCHASER.  In order to induce the
Company  to accept  this  subscription,  the  Purchaser  hereby  represents  and
warrants to, and covenants with, the Company as follows:

          (a) (i)   The undersigned understands  that the Shares  have not  been
      registered under the Securities Act of 1933, as amended (the "ACT") or the
      securities laws of any state, by reason of their contemplated  issuance in
      transactions  exempt from the prospectus and delivery  requirements of the
      Act  pursuant  to Section  4(2)  thereof,  and that the  reliance  on such
      exemption from registration is predicated in part on these representations
      and warranties of the Purchaser.  The Purchaser acknowledges that pursuant
      to Section 6(b) hereof a restrictive  legend consistent with the foregoing
      has been or will be placed on the  certificates  representing  the Shares.
      The  Purchaser  understands  that  neither  the  Securities  and  Exchange
      Commission  ("SEC") nor any state  securities  commission has approved the
      Shares or passed upon or endorsed the merits of the investment or reviewed
      or confirmed  the accuracy or determined  the adequacy of any  information
      furnished to the Purchaser in connection with the Offering.

              (ii)  The Purchaser is acquiring the Shares solely for the account
      of the Purchaser, for investment purposes only, and not with a view toward
      the resale or distribution  thereof.  The Purchaser  further agrees not to
      transfer  the  Shares  in  violation  of the Act or any  applicable  state
      securities  law, and no one other than the  Purchaser  has any  beneficial
      interest in the Shares;



                                       3
<PAGE>

              (iii) The Shares are and will be "restricted securities," as said
      term is defined in Rule 144 promulgated under the Act;

              (iv)  The  Purchaser  agrees  that it will  not sell or  otherwise
      dispose of any of the Shares unless such sale or other disposition (x) has
      been  registered  under the Act or, in the opinion of  counsel,  is exempt
      from  registration  under the Act and (y) has been registered or qualified
      or, in the  opinion  of such  counsel,  is  exempt  from  registration  or
      qualification  under  applicable  state securities laws. The Purchaser may
      not  sell,  transfer,  or  otherwise  dispose  of  the  Shares  except  in
      compliance with the applicable rules of the SEC;

              (v)   The  Purchaser is an "accredited  investor," as such term is
      defined in Rule 501(a) of Regulation D promulgated under the Act; and

              (vi)  The Purchaser is not an officer, director or "affiliate" (as
      that  term is  defined  in Rule  405  promulgated  under  the  Act) of the
      Company.

           (b)(i)   The  Purchaser  has  received  and  carefully  reviewed  the
      Company's Confidential Offering Memorandum dated as of October 9, 1998, as
      may be amended or supplemented from time to time (the "MEMORANDUM")  which

          (a) prepare  and file  with the SEC a  registration  statement  with
      respect to such Shares and use its best efforts to cause such registration
      statement to become and remain  effective  for such period,  not to exceed

      securities;

          (b) prepare and file with the SEC such  amendments and supplements to
      such  registration   statement  and  the  prospectus  used  in  connection

      effective for a period,  which need not exceed six months, and comply with
      the  provisions  of  the  Act  with  respect  to  the  disposition  of all
      securities  covered by such  registration  statement during such period in
      accordance  herewith and with the intended  methods of  disposition by the
      sellers thereof set forth in such registration statement;

          (c) furnish  to  each  seller  of  Shares  under  such  registration
      statement,  such  number of copies of such  registration  statement,  each
      amendment  and  supplement  thereto,   the  prospectus  included  in  such
      registration  statement  (including each preliminary  prospectus) and such
      other documents as such seller or underwriters  may reasonably  request in
      order to facilitate the disposition of the Shares, owned by such seller or
      the sale of such securities by such underwriters; and

          (d) register or qualify such Shares, under the securities or blue sky
      laws of such  jurisdictions in the United States as any seller  reasonably
      requests and do any and all other acts and things which may be  reasonably
      necessary or advisable to enable such seller to consummate the disposition
      in such  jurisdictions  of the  Shares,  owned by such  seller  (provided,
      however, that the Company will not be required (i) to qualify generally to
      do business in any  jurisdiction  where it would not otherwise be required
      to qualify but for this subparagraph or (ii) to subject itself to taxation
      in any such jurisdiction).

performance of or compliance with this Agreement, including, without limitation,
all  registration  and  filing  fees,  fees  and  expenses  of  compliance  with

expenses  of  underwriters,  underwriting  discounts,  selling  commissions  and
taxes),  and the fees and expenses of counsel  engaged by the sellers of Shares,
shall be the responsibility of such sellers.  In addition,  the Company will pay
its internal expenses (including,  without limitation, all salaries and expenses
of its  officers and  employees  performing  legal or  accounting  duties),  the
expense of any annual audit or quarterly  review,  the expense of any  liability

      10. INDEMNIFICATION - REGISTRATION.

          (a) The Company agrees to indemnify,  to the extent permitted by law,
      each seller of Shares,  its  officers  and  directors  and each person who
      controls  such seller  (within  the  meaning of the Act or the  Securities
      Exchange Act of 1934,  as amended  ("EXCHANGE  ACT"))  against all losses,
      claims, damages, liabilities and expenses (including,  without limitation,
      attorneys'  fees except as limited by Section  10(c)) caused by any untrue
      or  alleged  untrue   statement  of  a  material  fact  contained  in  any
      registration statement,  prospectus or any amendment thereof or supplement
      thereto or any omission or alleged omission of a material fact required to
      be stated therein or necessary to make the statements therein, in light of


                                       6
<PAGE>

      the  circumstances  under  which they were made,  not  misleading,  except
      insofar  as the  same  are  caused  by or  contained  in  any  information
      furnished  in writing  to the  Company by such  seller  expressly  for use
      therein or by such seller's  failure to deliver a copy of the registration
      statement or prospectus or any amendments or supplements thereto after the
      Company has  furnished  such seller with a sufficient  number of copies of
      the same. In connection  with an underwritten  offering,  the Company will
      indemnify such underwriters,  their officers and directors and each person
      who  controls  such  underwriters  (within  the  meaning of the Act or the
      Exchange  Act) to the same  extent as provided  above with  respect to the
      indemnification of the sellers of Shares.  The reimbursements  required by
      this Section 10(a) will be made by periodic  payments during the course of
      the  investigation or defense,  as and when bills are received or expenses
      incurred.

          (b) In connection with any  registration  statement in which a seller
      of Shares, is participating,  each such seller will furnish to the Company
      in writing  such  information  and  affidavits  as the Company  reasonably
      requests for use in  connection  with any such  registration  statement or
      prospectus  or any  amendment  thereof or  supplement  thereto and, to the
      extent  permitted by law, will  indemnify  the Company,  its directors and
      officers and each person who  controls the Company  (within the meaning of
      the  Act or  the  Exchange  Act)  against  any  losses,  claims,  damages,
      liabilities and expenses (including,  without limitation,  attorneys' fees
      except as limited by Section 10(c)) resulting from any untrue statement of
      a material fact  contained in the  registration  statement,  prospectus or
      preliminary  prospectus or any amendment thereof or supplement  thereto or
      any omission of a material fact required to be stated therein or necessary
      to make the statements  therein in light of the circumstances  under which
      they were made not  misleading,  but only to the extent  that such  untrue
      statement  or omission is  contained  in any  information  or affidavit so
      furnished  in writing by such  seller;  provided  that the  obligation  to
      indemnify  will be several,  not joint and several,  among such sellers of
      Shares,  and the  liability  of each  such  seller  of  Shares  will be in
      proportion  to, and provided  further that such  liability will be limited
      to,  the net  amount  received  by such  seller  from the  sale of  Shares
      pursuant to such registration statement.

          (c) Any person  entitled to  indemnification  hereunder will (i) give
      prompt written notice to the indemnifying  party of any claim with respect
      to which it seeks  indemnification  and (ii)  unless  in such  indemnified
      party's   reasonable   judgment  a  conflict  of  interest   between  such
      indemnified and indemnifying parties may exist with respect to such claim,
      permit  such  indemnifying  party to assume the defense of such claim with
      counsel reasonably satisfactory to the indemnified party. The indemnifying
      party will not be subject to any liability for any settlement  made by the
      indemnified  party  without  its  consent  (but such  consent  will not be
      unreasonably  withheld).  An indemnifying party who is not entitled to, or
      elects not to,  assume the defense of a claim will not be obligated to pay
      the fees and expenses of more than one counsel for all parties indemnified
      by such  indemnifying  party  with  respect to such  claim,  unless in the
      reasonable  judgment of any  indemnified  party a conflict of interest may
      exist  between such  indemnified  party and any other of such  indemnified
      parties with respect to such claim.

          (d) The indemnification provided for under this Agreement will remain
      in full force and effect  regardless  of any  investigation  made by or on
      behalf of the  indemnified  party or any officer,  director or controlling
      person of such indemnified  party and will survive the transfer of Shares.
      The Company and each seller of Shares also agrees to make such  provisions
      as are reasonably  requested by any indemnified  party for contribution to
      such party in the event the Company's or such seller's  indemnification is
      unavailable for any reason.

      11. CONFIDENTIALITY.  The  Purchaser  acknowledges  and  agrees  that all
information  relating to the Company and this subscription,  including,  but not
limited  to,  the  information  contained  in  the  Memorandum,  shall  be  kept
confidential  by the  Purchaser,  except as  otherwise  required  by law or made
public other than by or through the undersigned.

      12. NONTRANSFERABILITY. Neither this Subscription Agreement nor any of the
rights  of  the  Purchaser  hereunder  may be  transferred  or  assigned  by the
Purchaser.

Ladies and Gentlemen:

      This  letter   ("Letter")  waives  certain   requirements   found  in  the
Confidential  Private Placement Memoranda dated October 9, 1998, as amended, and
November 3, 1998,  as  amended,  (collectively,  "Memoranda")  pursuant to which
V-ONE Corporation  ("Company") is offering shares of the Company's common stock,
par value $0.001 per share ("Shares"). The Letter is being issued to LaSalle St.
Securities, Inc. in its capacity as Placement Agent for the Company.

      The Company  hereby  waives the $100,000  minimum  investment  requirement
found in the Memoranda.  There shall be no minimum investment  required in order
to  subscribe  for Shares in the  offering.  This waiver is  conditioned  on the

accompanying the Subscription Documents will be deposited in a segregated escrow

      If a prospective  investor has relied upon a purchaser  representative  in
connection  with  evaluating  the  purchase of Common  Stock,  such  prospective
investor   must  have  the   purchaser   representative   complete  a  Purchaser
Representative Questionnaire, which is available upon request from the Company.

V-ONE Corporation
20250 Century Boulevard - Suite 300
Germantown, Maryland 20874

Gentlemen:

      1.  PURCHASE AND SALE.  V-ONE  Corporation,  a Delaware  corporation  (the
"COMPANY"),   has  offered  for  sale,  and  the   undersigned   purchaser  (the
"PURCHASER")  hereby tenders this  subscription  and applies for the purchase of
the number of shares ("SHARES") of common stock, $0.001 par value per Share (the
"COMMON  STOCK") set forth on the Signature  Page at the purchase price of $2.00
(the "OFFERING PRICE"). The Offering is expected to expire on November 16, 1998,
subject to extension(s) by the mutual agreement of the Company and the Placement
Agent until  November 20, 1998  without  notice to  investors  (the  "EXPIRATION
DATE"). The Offering is conditioned upon the Company's receipt and acceptance of
subscriptions  for  1,800,000  shares  and the  Company's  receipt  of the  full
Purchase Price therefor  ($3,600,000) by the "Expiration  Date". The Company has
reserved the right to sell up to an  additional  922,070  shares (an  additional
$1,844,140  in gross sale  proceeds)  on the same  terms set forth  above in the
event this Offering is  oversubscribed  (the "Over  Subscription  Option").  The
Purchaser  must  subscribe  for a minimum  of 50,000  shares  ($100,000),  which
requirement may be waived in the Company's sole  discretion.  Together with this
Subscription  Agreement,  the  Purchaser is  delivering  to the Company the full
amount of the Purchase  Price for the shares (the "PURCHASE  PRICE")  subscribed
for. This  subscription may be rejected by the Company in its sole discretion in
whole or in  part.  THE  SIGNATURE  OF THE  UNDERSIGNED  ON THE  SIGNATURE  PAGE
CONSTITUTES THE EXECUTION OF THIS SUBSCRIPTION AGREEMENT.

      2.  AMOUNT AND METHOD OF PAYMENT. Payment of the  Purchase Price  required
to purchase the Shares  subscribed  for hereunder is being made by check payable
to  "LaSalle  National  Bank as  Escrow  Agent for  V-ONE  Corporation"  or wire
transfer in the amount of the Purchase Price for the undersigned's  subscription
to such account at the Escrow Agent (as previously  defined),  which  represents
payment  in full for the  subscribed  Shares.  If  payment is to be made by wire
transfer,  the Purchaser shall contact the Placement Agent to obtain appropriate
wire transfer instructions. If a subscription is rejected in whole or in part or
if the Offering is terminated for any reason, the Purchaser's subscription shall
be void and all funds  received from the Purchaser  shall be returned as soon as
practicable to the Purchaser without any interest thereon, and without charge or
deduction.

      3.  REPRESENTATIONS  AND  WARRANTIES OF PURCHASER.  In order to induce the
Company  to accept  this  subscription,  the  Purchaser  hereby  represents  and
warrants to, and covenants with, the Company as follows:

            (a) (i)     The  undersigned  understands  that the  Shares have not
      been  registered  under the Securities Act of 1933, as amended (the "ACT")
      or the  securities  laws of any  state,  by reason  of their  contemplated
      issuance  in   transactions   exempt  from  the  prospectus  and  delivery
      requirements  of the Act  pursuant to Section 4(2)  thereof,  and that the
      reliance on such  exemption  from  registration  is  predicated in part on
      these  representations  and  warranties  of the  Purchaser.  The Purchaser
      acknowledges  that  pursuant to Section 6(b) hereof a  restrictive  legend
      consistent  with  the  foregoing  has  been  or  will  be  placed  on  the
      certificates  representing  the Shares.  The  Purchaser  understands  that
      neither  the  Securities  and  Exchange  Commission  ("SEC") nor any state
      securities  commission  has approved the Shares or passed upon or endorsed
      the merits of the  investment  or reviewed or  confirmed  the  accuracy or
      determined the adequacy of any  information  furnished to the Purchaser in
      connection with the Offering.

                (ii)    The Purchaser is   acquiring  the Shares  solely for the
      account of the  Purchaser,  for  investment  purposes only, and not with a
      view toward the resale or  distribution  thereof.  The  Purchaser  further
      agrees  not  to  transfer  the  Shares  in  violation  of  the  Act or any
      applicable  state  securities law, and no one other than the Purchaser has
      any beneficial interest in the Shares;

                (iii)   The Shares are and  will  be "restricted securities," as
      said term is defined in Rule 144 promulgated under the Act;

                (iv)    The Purchaser agrees  that it will not sell or otherwise
      dispose of any of the Shares unless such sale or other disposition (x) has



                                       3
<PAGE>


      been  registered  under the Act or, in the opinion of  counsel,  is exempt
      from  registration  under the Act and (y) has been registered or qualified
      or, in the  opinion  of such  counsel,  is  exempt  from  registration  or
      qualification  under  applicable  state securities laws. The Purchaser may
      not  sell,  transfer,  or  otherwise  dispose  of  the  Shares  except  in
      compliance with the applicable rules of the SEC;

                (v)     The Purchaser is an "accredited investor," as such  term
      is defined in Rule 501(a) of Regulation D promulgated under the Act; and

                (vi)    The Purchaser is not an officer, director or "affiliate"
      (as that term is defined in Rule 405 promulgated under the Act) of the
      Company.

            (b) (i)     The  Purchaser  has  received and carefully reviewed the
      Company's Confidential Offering Memorandum dated as of October 9, 1998, as
      amended and  supplemented  by the Supplement (No. 1) thereto dated October
      9, 1998 and  Supplement No. 2 thereto dated November 9, 1998 and as may be
      further amended or supplemented from time to time (the "Memorandum") which
      Memorandum relates to the Shares covered by this Offering;

                (ii)    The  Purchaser has had a reasonable  opportunity to  ask
      questions of and receive  answers from the Company  concerning the Company
      and the  Offering  and to verify the  accuracy  of any  representation  or
      information set forth in the Memorandum,  and all such questions,  if any,
      have been answered to the full satisfaction of the Purchaser;

                (iii)   The Purchaser  has  received from  the Company, and  has
      reviewed,  such  information  which the Purchaser  considers  necessary or
      appropriate  to  evaluate  the risks and  merits of an  investment  in the
      Shares,  including  without  limitation,  the  Memorandum.  The  Purchaser
      acknowledges  that the  information  set forth  under the heading of "Risk
      Factors"  in  the  Memorandum  is  specifically   incorporated  herein  by
      reference and forms an integral part of this Subscription Agreement;

                (iv)    The  Purchaser  has  such  knowledge  and  expertise  in
      financial and business matters that the Purchaser is capable of evaluating
      the  merits  and  risks  involved  in an  investment  in  the  Shares  and
      acknowledges  that an  investment  in the Shares  entails a number of very
      significant  risks and funds  should only be invested if the  Purchaser is
      able to withstand the total loss of his investment;

                (v)     Except as set forth in this Subscription  Agreement,  no
      representations  or  warranties  have  been made to the  Purchaser  by the
      Company or any agent,  employee or affiliate of the Company. The Purchaser
      has  relied  solely  on the  representations,  warranties,  covenants  and
      agreements  of the  Company  in  this  Subscription  Agreement  and on the
      Purchaser's  examination  and  independent  investigation  in  making  its
      decision to acquire the Shares, including review of the Memorandum and the
      Company's current SEC filings;

                (vi)    The  Purchaser  understands  that the  Shares are  being
      offered and sold expressly  conditioned  upon the satisfaction of specific
      exemptions  from  the  registration  requirements  of  federal  and  state
      securities  laws  and that the  Company  is  relying  upon the  truth  and
      accuracy of the representations,  warranties, agreements,  acknowledgments
      and  understandings  of the  Purchaser set forth herein and in the related
      investor  questionnaire  in order to determine the  applicability  of such
      exemptions and the suitability of the Purchaser to acquire the Shares. The
      Purchaser acknowledges that it is solely the Purchaser's responsibility to
      satisfy itself as to the full  observance by this Offering and the sale of
      the Shares to  Purchaser  of the laws of any  jurisdiction  outside of the
      United  States  and  Purchaser  has done so and  that his or its  state or
      country of residence is set forth in such investor questionnaire;

                (vii)   If an individual, the Purchaser is over 21 years old and
      is legally competent to execute this Subscription Agreement; if an entity,
      the  Purchaser  is  duly  authorized  to  invest  in the  Shares,  and the
      individual signing this Subscription Agreement has been duly authorized by
      the Purchaser to do so;

                (viii)  The  Purchaser  has full power and authority to  execute
      and deliver this  Subscription  Agreement and to  perform  the Purchaser's


                                       4
<PAGE>


      obligations  hereunder,  and  this  Subscription  Agreement  is a  legally
      binding  obligation  of the  Purchaser  enforceable  against  Purchaser in
      accordance with its terms; and

                (ix)    The  Purchaser  has not incurred any  obligation for any
      finder's or broker's  agent's fees or commission  in  connection  with the
      transactions contemplated hereby.

            (c) All the  information which the undersigned has  furnished to the
      Company,  or which is set forth herein,  is correct and complete as of the
      date of this Subscription  Agreement,  and if there should be any material
      change in such  information,  the Purchaser will immediately  furnish such
      revised or  corrected  information  to the  Company.  Unless  the  Company
      receives  written  notice to the contrary from the Purchaser  prior to the
      Company's  acceptance of this subscription,  the Company shall be entitled
      to assume that the  preceding  is accurate in all  respects on the date of

      the  provisions  of  the  Act  with  respect  to  the  disposition  of all
      securities  covered by such  registration  statement during such period in
      accordance  herewith and with the intended  methods of  disposition by the
      sellers thereof set forth in such registration statement;

            (c) furnish  to  each  seller  of  Shares  under  such  registration
      statement,  such  number of copies of such  registration  statement,  each
      amendment  and  supplement  thereto,   the  prospectus  included  in  such
      registration  statement  (including each preliminary  prospectus) and such
      other documents as such seller or underwriters  may reasonably  request in
      order to facilitate the disposition of the Shares, owned by such seller or
      the sale of such securities by such underwriters; and

            (d) register or qualify such Shares,  under the  securities  or blue
      sky  laws  of  such  jurisdictions  in the  United  States  as any  seller
      reasonably  requests and do any and all other acts and things which may be
      reasonably  necessary or advisable to enable such seller to consummate the
      disposition  in such  jurisdictions  of the  Shares,  owned by such seller
      (provided,  however,  that the Company will not be required (i) to qualify
      generally to do business in any jurisdiction  where it would not otherwise
      be required to qualify but for this subparagraph or (ii) to subject itself
      to taxation in any such jurisdiction).

performance of or compliance with this Agreement, including, without limitation,
all  registration  and  filing  fees,  fees  and  expenses  of  compliance  with

relating  to the  offer  and sale of  Shares  pursuant  hereto  (e.g.,  fees and

of its  officers and  employees  performing  legal or  accounting  duties),  the
expense of any annual audit or quarterly  review,  the expense of any  liability
insurance  obtained  by the Company  and the  expenses  and fees for listing the

      10. INDEMNIFICATION - REGISTRATION.

            (a) The Company agrees to indemnify, to the extent permitted by law,
      each seller of Shares,  its  officers  and  directors  and each person who
      controls  such seller  (within  the  meaning of the Act or the  Securities
      Exchange Act of 1934,  as amended  ("EXCHANGE  ACT"))  against all losses,
      claims, damages, liabilities and expenses (including,  without limitation,
      attorneys'  fees except as limited by Section  10(c)) caused by any untrue
      or  alleged  untrue   statement  of  a  material  fact  contained  in  any
      registration statement,  prospectus or any amendment thereof or supplement
      thereto or any omission or alleged omission of a material fact required to
      be stated therein or necessary to make the statements therein, in light of
      the  circumstances  under  which they were made,  not  misleading,  except
      insofar  as the  same  are  caused  by or  contained  in  any  information
      furnished  in  writing  to the Company  by such  seller  expressly for use


                                       6

      therein or by such seller's  failure to deliver a copy of the registration
      statement or prospectus or any amendments or supplements thereto after the
      Company has  furnished  such seller with a sufficient  number of copies of
      the same. In connection  with an underwritten  offering,  the Company will
      indemnify such underwriters,  their officers and directors and each person
      who  controls  such  underwriters  (within  the  meaning of the Act or the
      Exchange  Act) to the same  extent as provided  above with  respect to the
      indemnification of the sellers of Shares.  The reimbursements  required by
      this Section 10(a) will be made by periodic  payments during the course of
      the  investigation or defense,  as and when bills are received or expenses
      incurred.

            (b) In connection with any registration  statement in which a seller
      of Shares, is participating,  each such seller will furnish to the Company
      in writing  such  information  and  affidavits  as the Company  reasonably
      requests for use in  connection  with any such  registration  statement or
      prospectus  or any  amendment  thereof or  supplement  thereto and, to the
      extent  permitted by law, will  indemnify  the Company,  its directors and
      officers and each person who  controls the Company  (within the meaning of
      the  Act or  the  Exchange  Act)  against  any  losses,  claims,  damages,
      liabilities and expenses (including,  without limitation,  attorneys' fees
      except as limited by Section 10(c)) resulting from any untrue statement of
      a material fact  contained in the  registration  statement,  prospectus or
      preliminary  prospectus or any amendment thereof or supplement  thereto or
      any omission of a material fact required to be stated therein or necessary
      to make the statements  therein in light of the circumstances  under which
      they were made not  misleading,  but only to the extent  that such  untrue
      statement  or omission is  contained  in any  information  or affidavit so
      furnished  in writing by such  seller;  provided  that the  obligation  to
      indemnify  will be several,  not joint and several,  among such sellers of
      Shares,  and the  liability  of each  such  seller  of  Shares  will be in
      proportion  to, and provided  further that such  liability will be limited
      to,  the net  amount  received  by such  seller  from the  sale of  Shares
      pursuant to such registration statement.

            (c) Any person entitled to  indemnification  hereunder will (i) give
      prompt written notice to the indemnifying  party of any claim with respect
      to which it seeks  indemnification  and (ii)  unless  in such  indemnified
      party's   reasonable   judgment  a  conflict  of  interest   between  such
      indemnified and indemnifying parties may exist with respect to such claim,
      permit  such  indemnifying  party to assume the defense of such claim with
      counsel reasonably satisfactory to the indemnified party. The indemnifying
      party will not be subject to any liability for any settlement  made by the
      indemnified  party  without  its  consent  (but such  consent  will not be
      unreasonably  withheld).  An indemnifying party who is not entitled to, or
      elects not to,  assume the defense of a claim will not be obligated to pay
      the fees and expenses of more than one counsel for all parties indemnified
      by such  indemnifying  party  with  respect to such  claim,  unless in the
      reasonable  judgment of any  indemnified  party a conflict of interest may
      exist  between such  indemnified  party and any other of such  indemnified
      parties with respect to such claim.

            (d) The  indemnification  provided  for under  this  Agreement  will
      remain in full force and effect regardless of any investigation made by or
      on behalf of the indemnified party or any officer, director or controlling
      person of such indemnified  party and will survive the transfer of Shares.
      The Company and each seller of Shares also agrees to make such  provisions
      as are reasonably  requested by any indemnified  party for contribution to
      such party in the event the Company's or such seller's  indemnification is
      unavailable for any reason.

            1.1 EXERCISE AT OPTION OF HOLDER. This Warrant may be  exercised  by
the Holder hereof in full or in part at any time or from time to time during the
exercise  period  specified in the first  paragraph  hereof until the Expiration
Date by surrender of this Warrant and the subscription form annexed hereto (duly
executed) by such Holder, to the Company at its principal office, accompanied by
payment,  in cash or by certified or official bank check payable to the order of
the Company in the amount  obtained by  multiplying  (a) the number of shares of
Common  Stock  designated  by the  Holder  in the  subscription  form by (b) the
Purchase  Price  then in effect.  On any  partial  exercise,  the  Company  will
forthwith  issue and  deliver  to or upon the order of the  Holder  hereof a new
Warrant or Warrants of like tenor,  in the name of the Holder  hereof or as such
Holder  (upon  payment  by such  Holder of any  applicable  transfer  taxes) may
request,  providing  in the  aggregate  on the  face or  faces  thereof  for the
purchase  of the  number of shares of Common  Stock for which  such  Warrant  or
Warrants may still be exercised.

            1.2 NET ISSUANCE. Notwithstanding anything to the contrary contained
in Section  1.1,  the Holder may elect to exercise  this  Warrant in whole or in
part by receiving  shares of Common  Stock equal to the net  issuance  value (as
determined  below) of this Warrant,  or any part hereof,  upon surrender of this
Warrant at the  principal  office of the  Company  together  with notice of such
election,  in which  event the  Company  shall  issue to the  Holder a number of
shares of Common Stock computed using the following formula:

            X = Y (A-B)
                -------  
                   A

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

                  Y     = the number of shares of Common  Stock as to which this
                        Warrant is to be exercised

                  A     = the "current  fair market value of one share of Common
                        Stock"  (as  defined  below)  calculated  as of the last
                        trading day  immediately  preceding the exercise of this
                        Warrant

                  B =   the Purchase Price

            As used  herein,  "current  fair market value of one share of Common
Stock" as of a  specified  date shall mean with  respect to each share of Common
Stock the average of the closing bid prices of the Common Stock on the principal
securities  market on which the  Common  Stock may at the time be traded  over a
period of five Business Days  consisting of the day as of which the current fair
market value of a share of Common Stock is being  determined  (or if such day is
not a Business  Day,  the  Business  Day next  preceding  such day) and the four
consecutive  Business  Days prior to such day. If on the date for which  current
fair market  value is to be  determined  the Common  Stock is not  eligible  for
trading on any securities  market, the current fair market value of Common Stock
shall be the highest  price per share that the Company  could then obtain from a
willing  buyer (not a current  employee or director)  for shares of Common Stock
sold by the Company,  from authorized but unissued shares, as determined in good
faith by the Board of Directors  of the  Company,  unless prior to such date the
Company  has become  subject  to a merger,  acquisition  or other  consolidation
pursuant  to which the  Company is not the  surviving  party,  in which case the
current  fair market  value of the Common  Stock shall be deemed to be the value
received by the holders of the  Company's  Common  Stock for each share  thereof
pursuant to the Company's acquisition.

            2. DELIVERY OF STOCK  CERTIFICATES,  ETC.,  ON EXERCISE.  As soon as
practicable  after the exercise of this  Warrant,  and in any event within three
days thereafter,  the Company at its expense (including the payment by it of any
applicable  issue or stamp  taxes)  will  cause to be  issued in the name of and
delivered to the Holder  hereof,  or as such Holder (upon payment by such Holder
of any applicable  transfer taxes) may direct, a certificate or certificates for
the  number of fully  paid and  nonassessable  shares of Common  Stock (or Other
Securities)  to which such Holder  shall be entitled on such  exercise,  in such
denominations  as  may be  requested  by  such  Holder,  plus,  in  lieu  of any
fractional share to which such Holder would otherwise be entitled, cash equal to
such fraction multiplied by the then current fair market value (as determined in
accordance with subsection 1.2) of one full share, together with any other stock
or other securities any property  (including  cash,  where  applicable) to which
such Holder is entitled upon such  exercise  pursuant to Section 1 or otherwise.
Upon exercise of this Warrant as provided  herein,  the Company's  obligation to
issue and  deliver the  certificates  for Common  Stock  shall be  absolute  and
unconditional,  irrespective  of any action or inaction by the Holder to enforce
the same,  any waiver or consent  with  respect to any  provision  thereof,  the
recovery of any  judgment  against any person or any action to enforce the same,
any failure or delay in the  enforcement of any other  obligation of the Company
to  the  Holder,  or  any  setoff,  counterclaim,   recoupment,   limitation  or
termination,  or any breach or alleged  breach by the Holder or any other person
of any obligation to the Company or any violation or alleged violation of law by
the Holder or any other person,  and irrespective of any other circumstance that
might otherwise limit such obligation of the Company to the Holder in connection
with such exercise.  If the Company fails to issue and deliver the  certificates
for the  Common  Stock to the  Holder  pursuant  to the first  sentence  of this
paragraph  as and when  required to do so, in addition to any other  liabilities
the Company may have hereunder and under  applicable  law, the Company shall pay
or  reimburse  the Holder on demand for all  out-of-pocket  expenses  including,
without limitation, fees and expenses of legal counsel incurred by the Holder as
a result of such failure.

            3.  ADJUSTMENT  FOR  DIVIDENDS  IN  OTHER  STOCK,  PROPERTY,   ETC.;
RECLASSIFICATION, ETC. In case at any time or from time to time, all the holders
of Common Stock (or Other Securities)  shall have received,  or (on or after the
record date fixed for the  determination  of  stockholders  eligible to receive)
shall have become entitled to receive, without payment therefor,

            (a) other or additional stock or other securities or property (other
      than cash) by way of dividend, or

            (b)  any  cash  (excluding  cash  dividends  payable  solely  out of
      earnings or earned surplus of the Company), or

            (c)  other  or  additional  stock or other  securities  or  property
      (including   cash)  by  way  of  spin-off,   split-up,   reclassification,
      recapitalization,    combination   of   shares   or   similar    corporate
      rearrangement,

other than additional shares of Common Stock (or Other  Securities)  issued as a
stock dividend or in a stock-split (adjustments in respect of which are provided
for in Section 5), then and in each such case the Holder of this Warrant, on the
exercise  hereof as  provided  in Section 1, shall be  entitled  to receive  the
amount of stock and other  securities and property  (including cash in the cases
referred  to in  subdivisions  (b) and (c) of this  Section 3) that such  Holder
would  hold on the date of such  exercise  if on the date  hereof the Holder had
been the holder of record of the number of shares of Common  Stock called for on
the face of this  Warrant  and had  thereafter,  during the period from the date
hereof to and including the date of such exercise,  retained such shares and all
such other or additional stock and other securities and property (including cash
in the  case  referred  to in  subdivisions  (b)  and  (c) of  this  Section  3)
receivable by the Holder as aforesaid  during such period,  giving effect to all
adjustments called for during such period by Section 4.

            4. EXERCISE UPON REORGANIZATION, CONSOLIDATION, MERGER, ETC. In case
at any time or from time to time, the Company shall (a) effect a reorganization,
(b) consolidate  with or merge into any other person,  (c) effect an exchange of
outstanding  shares of the Company  for  securities  of any other  person or (d)
transfer  all or  substantially  all of its  properties  or  assets to any other
person  under  any plan or  arrangement  contemplating  the  dissolution  of the
Company,  then,  in each  such  case,  as a  condition  of such  reorganization,
consolidation,  merger,  share exchange,  sale or conveyance,  the Company shall
cause  effective  provisions  to be made so that the Holder shall have the right
thereafter, by exercising this Warrant (in lieu of the shares of Common Stock of
the Company  purchasable and receivable upon exercise of the rights  represented
hereby immediately prior to such transaction) to purchase the kind and amount of
shares of stock and other  securities and property  (including  cash) receivable
upon  such  reorganization,  consolidation,  merger,  share  exchange,  sale  or
conveyance  by a holder of the number of shares of Common  Stock that might have
been  received  upon  exercise  of  this  Warrant   immediately  prior  to  such
reorganization,  consolidation,  merger,  share  exchange,  sale or  conveyance;
PROVIDED,  HOWEVER, that in the event (a) the value of the stock,  securities or
other assets or property  (determined in good faith by the Board of Directors of
the  Company)  issuable or payable  with respect to one share of Common Stock of
the  Company  purchasable  and  receivable  upon  the  exercise  of  the  rights


                                      -4-
<PAGE>

represented  hereby  immediately  prior to such  transaction is in excess of the
Purchase   Price   hereof  in  effect  at  the  time  of  such   reorganization,
consolidation,  merger, share exchange,  sale or conveyance (after giving effect
to any  adjustment in such Purchase Price required to be made under the terms of
this  Warrant),  and  (b)  the  securities,  if  any,  to be  received  in  such
reorganization,  consolidation,  merger, share exchange,  sale or conveyance are
publicly traded,  then if the Company gives the Holder at least 20 Business Days
(or such lesser  period as the Company gives notice of such  transaction  to the
holders  of the  outstanding  shares  of  Common  Stock)  prior  notice  of such
reorganization,  merger,  share exchange,  sale or conveyance this Warrant shall
expire unless  exercised prior to such  reorganization,  consolidation,  merger,
share exchange, sale or conveyance.  Any such provision shall include provisions
for  adjustments  in respect of such  shares of stock and other  securities  and
property  that  shall  be as  nearly  equivalent  as may be  practicable  to the
adjustments  provided for in this Warrant.  The provisions of this Section shall
apply to successive reorganizations,  consolidations,  mergers, share exchanges,
sales and conveyances.

            5.  ADJUSTMENT  FOR  EXTRAORDINARY  EVENTS.  In the  event  that the
Company shall (i) issue  additional  shares of the Common Stock as a dividend or
other distribution on outstanding Common Stock, (ii) subdivide or reclassify its
outstanding  shares of Common Stock, or (iii) combine its outstanding  shares of
Common Stock into a smaller number of shares of Common Stock, then, in each such
event,  the Purchase  Price  shall,  simultaneously  with the  happening of such
event,  be adjusted by multiplying  the then Purchase  Price by a fraction,  the
numerator  of which  shall be the number of shares of Common  Stock  outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common  Stock  outstanding  immediately  after such event,  and the
product so obtained shall  thereafter be the Purchase Price then in effect.  The
Purchase Price, as so adjusted,  shall be readjusted in the same manner upon the
happening of any successive  event or events described herein in this Section 5.
The Holder of this Warrant shall thereafter,  on the exercise hereof as provided
in  Section 1, be  entitled  to receive  that  number of shares of Common  Stock
determined  by  multiplying  the number of shares of Common  Stock that would be
issuable on such exercise as of immediately prior to such issuance by a fraction
of which (i) the numerator is the Purchase Price in effect  immediately prior to
such issuance and (ii) the  denominator  is the Purchase  Price in effect on the
date of such exercise.

            6. FURTHER ASSURANCES.  The Company will take all action that may be
necessary or appropriate in order that the Company may validly and legally issue
fully paid and  nonassessable  shares of stock,  free from all taxes,  liens and
charges with respect to the issue thereof, on the exercise of all or any portion
of this Warrant from time to time outstanding.

            7.  NOTICES OF RECORD DATE, ETC.  In the event of

            (a) any  taking by the  Company  of a record of the  holders  of any
      class of securities for the purpose of determining the holders thereof who
      are entitled to receive any  dividend  on, or any right to subscribe  for,
      purchase  or  otherwise  acquire  any  shares of stock of any class or any
      other securities or property, or to receive any other right, or

            (b) any capital  reorganization of the Company, any reclassification
      or recapitalization of the capital stock of the Company or any transfer of
      all or substantially  all of the assets of the Company to or consolidation
      or merger of the Company with or into any other person, or

            (c) any  voluntary  or  involuntary  dissolution,   liquidation  or
      winding-up of the Company,

then and in each such event the  Company  will mail or cause to be mailed to the
Holder, at least ten days prior to such record date, a notice specifying (i) the
date on which any such record is to be taken for the  purpose of such  dividend,
distribution  or right,  and stating the amount and character of such  dividend,
distribution  or  right,  (ii)  the  date  on  which  any  such  reorganization,
reclassification,    recapitalization,    transfer,    consolidation,    merger,
dissolution, liquidation or winding-up is to take place, and the time, if any is
to be fixed,  as of which  the  holders  of  record  of  Common  Stock (or Other
Securities) shall be entitled to exchange their shares of Common Stock (or Other
Securities) for securities or other property deliverable on such reorganization,
reclassification,    recapitalization,    transfer,    consolidation,    merger,
dissolution,  liquidation or  winding-up,  and (iii) the amount and character of
any stock or other  securities,  or  rights or  options  with  respect  thereto,
proposed to be issued or granted,  the date of such proposed  issue or grant and
the  persons or class of persons to whom such  proposed  issue or grant is to be
offered or made. Such notice shall also state that the action in question or the
record date is subject to the  effectiveness  of a registration  statement under
the Securities Act of 1933, as amended (the  "Securities  Act"),  or a favorable
vote of stockholders if either is required. Such notice shall be mailed at least
ten days prior to the date  specified in such notice on which any such action is
to be taken or the record date, whichever is earlier.

            8. RESERVATION OF STOCK, ETC., ISSUABLE ON EXERCISE OF WARRANTS. The
Company will at all times  reserve and keep  available,  solely for issuance and
delivery on the exercise of this  Warrant,  all shares of Common Stock (or Other
Securities) from time to time issuable on the exercise of this Warrant.

            9.  TRANSFER OF WARRANT.  This Warrant shall inure to the benefit of

authorized attorney, upon surrender of this Warrant properly endorsed.

            10.  REGISTER  OF  WARRANTS.  The  Company  shall  maintain,  at the
principal  office of the Company (or such other  office as it may  designate  by
notice to the Holder  hereof),  a register in which the Company shall record the
name and address of the person in whose name this  Warrant has been  issued,  as

<PAGE>

well as the name and address of each  successor and prior owner of such Warrant.
The Company  shall be entitled to treat the person in whose name this Warrant is
so registered as the sole and absolute owner of this Warrant for all purposes.

            11.  EXCHANGE OF WARRANT.  This  Warrant is  exchangeable,  upon the
surrender  hereof by the Holder  hereof at the  office or agency of the  Company
referred  to in  Section  10,  for  one or  more  new  Warrants  of  like  tenor
representing in the aggregate the right to subscribe for and purchase the number
of shares of Common Stock that may be subscribed for purchase hereunder, each of
such new Warrants to  represent  the right to  subscribe  for and purchase  such
number of shares as shall be  designated  by said  Holder  hereof at the time of
such surrender.

            12.  REPLACEMENT  OF  WARRANT.  On  receipt of  evidence  reasonably
satisfactory  to the Company of the loss,  theft,  destruction  or mutilation of
this Warrant  and, in the case of any such loss,  theft or  destruction  of this
Warrant,   on  delivery  of  an  indemnity   agreement  or  security  reasonably
satisfactory  in form and  amount  to the  Company  or,  in the case of any such
mutilation,  on surrender and  cancellation of this Warrant,  the Company at its
expense will execute and deliver, in lieu thereof, a new Warrant of like tenor.

            13. WARRANT AGENT. The Company may, by written notice to the Holder,

purpose of issuing  Common Stock (or Other  Securities)  on the exercise of this
Warrant  pursuant to Section 1, exchanging this Warrant  pursuant to Section 11,
and replacing this Warrant pursuant to Section 12, or any of the foregoing,  and
thereafter any such issuance, exchange or replacement, as the case may be, shall

            14. REMEDIES. The Company stipulates that the remedies at law of the
Holder of this Warrant in the event of any default or threatened  default by the
Company  in the  performance  of or  compliance  with  any of the  terms of this

specifically  enforced by a decree for the specific performance of any agreement
contained  herein or by an  injunction  against a violation  of any of the terms
hereof or otherwise.

            15. NO RIGHTS OR LIABILITIES  AS A  STOCKHOLDER.  This Warrant shall
not  entitle  the  Holder  hereof  to any  voting  rights  or other  rights as a
stockholder  of the Company.  No provision  of this  Warrant,  in the absence of
affirmative  action by the Holder hereof to purchase  Common Stock,  and no mere
enumeration herein of the rights or privileges of the Holder hereof,  shall give
rise to any liability of such Holder for the Purchase  Price or as a stockholder
of the  Company,  whether  such  liability  is  asserted  by the  Company  or by
creditors of the Company.

            16. NOTICES,  ETC.  All notices and other  communications  from  the
Company to the registered  Holder of this Warrant shall be mailed by first class

            17. INVESTMENT  REPRESENTATIONS.  By acceptance of this Warrant, the
Holder  represents  to the Company that this  Warrant is being  acquired for the


                                      -7-
<PAGE>

Holder's own account and for the purpose of  investment  and not with a view to,
or for sale in connection with, the distribution  thereof,  nor with any present
intention of  distributing  or selling the Warrant or the Common Stock  issuable
upon exercise of the Warrant.  The Holder  acknowledges that the Holder has been
afforded the  opportunity  to meet with the management of the Company and to ask
questions  of, and receive  answers  from,  such  management  and the  Company's
counsel about the business and affairs of the Company and  concerning  the terms
and  conditions  of the offering of this Warrant,  and to obtain any  additional
information,  to the extent that the Company possessed such information or could
acquire it  without  unreasonable  effort or  expense,  necessary  to verify the
accuracy of the information  otherwise obtained by or furnished to the Holder in
connection  with the offering of this Warrant.  The Holder asserts that it is an
"accredited  investor" as defined in Rule 501(a)(3) under the Securities Act, it
may be considered  to be a  sophisticated  investor,  is familiar with the risks
inherent in speculative  investments such as in the Company,  has such knowledge
and  experience  in  financial  and  business  matters  that  it is  capable  of
evaluating the merits and risks of the investment in this Warrant and the Common
Stock  issuable upon exercise of this Warrant,  and is able to bear the economic
risk of the  investment.  The Holder  acknowledges  and agrees that this Warrant
and,  except as otherwise  provided in the Placement Agent Agreement dated as of
October 9, 1998 between LaSalle St. Securities, Inc. and the Company, as amended
or modified on the date hereof and as subsequently amended or modified from time
to time (the "Placement Agreement"),  the Common Stock issuable upon exercise of
this  Warrant  (if any)  have not been  (and at the time of  acquisition  by the
Holder,  will not have been or will not be), registered under the Securities Act
or under the securities  laws of any state,  in reliance upon certain  exemptive
provisions of such statutes.  The Holder  recognizes and acknowledges  that such
claims of exemption are based, in part, upon the  representations  of the Holder
contained herein.  The Holder further  recognizes and acknowledges that, because
this  Warrant and,  except as provided in the  Placement  Agreement,  the Common
Stock issuable upon exercise of this Warrant (if any) are unregistered, they may
not be eligible for resale,  and may only be resold in the future pursuant to an
effective  registration  statement  under the  Securities Act and any applicable
state securities  laws, or pursuant to a valid exemption from such  registration
requirements. Unless the shares of Common Stock have theretofore been registered
for resale or are otherwise exempt from  registration  under the Securities Act,
the Company may require, as a condition to the issuance of Common Stock upon the
exercise  of this  Warrant (i) in the case of an  exercise  in  accordance  with
Section 1.1 hereof,  a  confirmation  as of the date of exercise of the Holder's
representations  pursuant to this  Section 17 or (ii) in the case of an exercise
in  accordance  with  Section  1.2  hereof,  an opinion  (in form and  substance
reasonably  satisfactory to the Company) of counsel  reasonably  satisfactory to
the Company that the shares of Common Stock to be issued upon such  exercise may
be issued without registration under the Securities Act.

            18. LEGEND.  Unless  theretofore  registered  for resale  under  the
Securities Act or otherwise exempt from registration under the Securities Act in
a manner that would no longer  require such legend when issued upon  exercise of
this Warrant and when resold thereafter, each certificate for shares issued upon
exercise of this Warrant shall bear the following legend:

            The  securities  represented  by  this  certificate  have  not  been
            registered under the Securities Act of 1933, as amended (the "Act"),
            or any  state  securities  laws.  The  sale to the  holder  of these
            securities is not covered by a registration  statement under the Act


                                      -8-
<PAGE>

            or registration  under state  securities laws. These securities have
            been acquired for investment  only and may not be sold,  transferred
            or assigned in the absence of  registration of the resale thereof or
            an opinion of counsel reasonably acceptable to the Company that such
            registration is not required.

            19. MISCELLANEOUS. This Warrant and any terms hereof may be changed,
waived,  discharged or terminated only by an instrument in writing signed by the
party against which enforcement or such change, waiver, discharge or termination
is sought.  This Warrant shall be construed and enforced in accordance  with and
governed by the  internal  laws of the State of New York.  The  headings in this
Warrant are for  purposes of  reference  only,  and shall not limit or otherwise
affect  any of the terms  hereof.  The  invalidity  or  unenforceability  of any
provision  hereof shall in no way affect the validity or  enforceability  of any
other provision.

            IN WITNESS WHEREOF,  V-ONE Corporation has caused this Warrant to be
executed on its behalf by one of its officers thereunto duly authorized.
