"Landlord"), MTI Technology Corporation - (the "Tenant"), and WebCommerce Group,
LLC - (the "Subtenant") do hereby enter into this Consent to Sublease and
Agreement (this "Agreement").

                                    RECITALS

                  WHEREAS, Landlord and Tenant entered into a lease (the
"Lease") dated April 26, 2000 for approximately 2635 rentable square feet of
office space in the building commonly known as the Cii Building, located in Wake
County, Raleigh, North Carolina (the "Subleased Premises");

                  AND WHEREAS, Tenant and Subtenant have agreed to enter into a
sublease of the Subleased Premises in the form attached hereto and incorporated
herein by reference (the "Sublease");

                  NOW THEREFORE, in consideration of the premises and other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, Landlord, Tenant and Subtenant agree as follows:

         1.       Any capitalized terms used in this Agreement that are not
                  defined herein shall have the meaning given such terms in the
                  Lease or Sublease, as applicable.

         2.       Landlord has reviewed and approved the provisions of the
                  Sublease and hereby consents to the terms and conditions
                  thereof.

         3.       Tenant shall not be released in any manner from any of its
                  obligations, covenants, agreements, liabilities and duties
                  under the Lease and any amendments thereto, including but not
                  limited to, Tenant's duty to pay or cause to be paid all rent
                  due thereunder.

         4.       Tenant shall pay to Landlord, as additional rent, all rents
                  received by Tenant from Subtenant in excess of the rent
                  payable by Tenant to Landlord under the Lease.

         5.       The Sublease is, in all respects, subject and subordinated to
                  the Lease. Without limiting the foregoing, no use or occupancy
                  of the Subleased Premises shall be permitted by Tenant or
                  undertaken by Subtenant which is in any way inconsistent with
                  the terms and provisions of the Lease. Subtenant agrees to
                  comply with all provisions of the Lease, including Section 10
                  of the Lease, entitled "Tenant's Compliance; Insurance
                  Requirements", and the requirement that Landlord be named as
                  an additional insured. Subtenant and Tenant hereby agree that
                  they are and will be jointly and severally liable for the
                  performance of the agreements, conditions, covenants and terms
                  of the Lease.

         6.       Landlord shall not be obligated to Subtenant under any of the
                  provisions of the Sublease.

         7.       Subtenant shall indemnify and hold Landlord harmless from and
                  against any and all claims arising out of (a) Subtenant's use
                  of the Subleased Premises or any part thereof; (b) any
                  activity, work, or other thing done, permitted or suffered by
                  Subtenant in or about the Subleased Premises or the building,
                  or any part thereof; (c) any breach or default by Subtenant in
                  the performance of any of its obligations under the Sublease
                  or this Agreement; or (d) any act or negligence of Subtenant,
                  or any officer, agent, employee, contractor, servant, invitee
                  or guest of Subtenant; and in each case from and against any
                  and all damages, losses, liabilities, lawsuits, costs and
                  expenses (including attorneys' fees at all tribunal levels)
                  arising in connection with any such

<PAGE>

                  claim or claims as described in (a) through (d) above, or any
                  action brought thereon. If such action is brought against
                  Landlord, Subtenant upon notice from Landlord shall defend the
                  same through counsel selected by Subtenant's insurer or other
                  counsel, in each case acceptable to Landlord. Subtenant
                  assumes all risk of damage or loss to its property or injuries
                  or death to persons in, on, or about the Subleased Premises,
                  from all causes except those for which the law imposes
                  liability on Landlord regardless of any attempted waiver
                  thereof, and Subtenant hereby waives such claims in respect
                  thereof against Landlord. The provisions of this paragraph
                  shall survive the termination of the Sublease.

         8.       This Agreement shall not be deemed to constitute a consent to
                  any future sublease (or any future assignment) and each and
                  every such proposed future sublease (and any proposed future
                  assignment) shall require the prior written consent of
                  Landlord, which Landlord may not arbitrarily refuse to give.

         9.       The termination of the Lease by lapse of time or as otherwise
                  provided in the Lease shall immediately cause the Sublease to
                  be terminated and have no further force or effect; provided,
                  however, that Subtenant agrees, at the election and upon the
                  written demand of Landlord, to attorn to Landlord upon the
                  terms and conditions set forth in the Sublease for the
                  remainder of the term of the Sublease. The foregoing
                  provisions of this paragraph shall apply notwithstanding that,
                  as a matter of law, the Sublease may otherwise terminate upon
                  the termination of the Lease and shall be self-operative upon
                  such written demand of the Landlord, and no further instrument
                  shall be required to give effect to said provisions.

         10.      Any options provided to Tenant in the Lease shall not be
                  extended to or exercised by Subtenant.

         11.      Landlord, hereby represents and warrants to Subtenant that, as
                  of the date of this agreement, to Landlord's knowledge, no
                  defaults exist by either party under the lease, nor does there
                  exist any fact or circumstance which, with the passage of
                  time, could become a default under the Lease.

         12.      Landlord agrees to provide the Subtenant a copy of any notice
                  of default that Landlord shall provide to Tenant under the
                  Lease, at the same time as such notice is provided to Tenant,
                  at the address of the Subleased Premises, and otherwise
                  pursuant to Section 19 of the Lease, and, then, Subtenant
                  shall thereafter have the concurrent right as may be granted
                  to Tenant under the Lease to effect a cure of such default,
                  and Landlord shall accept such cure from Subtenant, provided,
                  however, that Subtenant shall have no obligation to effect any
                  cure, such action being at Subtenant's option.

         13.      If Landlord terminates the Lease and the Sublease because of a
                  default by Tenant that remains uncured by Tenant and Subtenant
                  beyond any applicable cure period, Subtenant shall have thirty
                  (30) days to vacate the Subleased Premises.

         14.      Subtenant and Tenant hereby agree that upon receipt of written
                  notice from Landlord certifying that Tenant is in default,
                  Subtenant shall pay directly to Landlord, rather than to
                  Tenant, all rent and other sums that become due and payable by
                  Subtenant under the Lease.

         15.      Subtenant agrees to deliver to Landlord copies of all notices
                  of default and other notices or correspondence pertaining to
                  non-compliance with the Sublease received by Subtenant. Tenant
                  agrees to deliver to Landlord copies of all notices of default
                  and other notices or correspondence pertaining to
                  non-compliance with the Sublease received by Tenant.

         16.      Notwithstanding anything herein or the Sublease to the
                  contrary, Landlord hereby consents to the provisions of the
                  Sublease with respect to the assignment by Tenant to Subtenant
                  of Tenant's privity and right to enforce the Lease (and
                  Landlord's obligations thereunder) against Landlord.

         17.      This Agreement is entered into under the laws of the State of
                  North Carolina and those laws shall govern the construction
                  and enforcement of this Agreement.

                  IN WITNESS WHEREOF, the parties have executed this Consent to
Sublease and Agreement under seal as of the day and year first written above.
