Mr. Edison Velez

San Juan, PR  00918

Dear Mr. Velez:

We are pleased to detail herein below the provisions of your employment
agreement with Doral Mortgage Corporation ("DMC").

1.       TERMS OF EMPLOYMENT

         The term of this Agreement shall be for a period commencing on January
         1, 1999 and ending December 31, 2000 unless sooner terminated as
         herein provided. This Agreement supersedes and cancels all prior
         employment, personal service or similar agreements between you and DMC
         or First Financial Caribbean Corporation ("FFCC") and their respective
         subsidiaries, divisions and ventures.

2.       POSITION AND RESPONSIBILITIES

         You will serve as President of DMC. By your acceptance of this
         Agreement, you undertake to accept such employment, to devote your
         full time and attention to DMC, and to use your best efforts, ability,
         and fidelity in the performance of the duties attaching to such
         employment. During the term of your employment hereunder, you shall
         not perform any services for any other company, which services
         conflict in any way with your obligations under the two preceding
         sentences of this Section 2, whether or not such company is
         competitive with the businesses DMC or FFCC, provided, however, that
         nothing in this Agreement shall preclude you from devoting reasonable
         periods required for

         (i)      serving as a director or member of a committee of any
                  organization involving no conflict or potential conflict of
                  interest with the interests of DMC or FFCC;

         (ii)     delivering lectures, fulfilling speaking engagements,
                  teaching at educational institutions;

         (iii)    engaging in charitable and community activities; and

         (iv)     managing your personal and family investments, provided that
                  such activities do not interfere with the regular performance
                  of your duties and responsibilities under this Agreement.

You shall, at all times during the term hereof, be subject to the supervision
and direction of the Chief Executive Officer and Chairman of the Board of DMC
with respect to your duties, responsibilities and the exercise of your powers.

3.       COMPENSATION

         (a)      During the term of this Agreement you shall receive an annual
                  salary of Two Hundred Forty Thousand dollars ($240,000.00)
                  annually payable no less often than monthly in accordance with
                  corporate policy.

         (b)      (i) During the term of this Agreement, you shall also be
                  entitled to receive an incentive bonus equal to the lesser of
                  Three Hundred Thousand Dollars ($300,000.00) and (y) Three
                  Percent (3%) based on the net income of Doral Mortgage
                  Corporation over and above Three Million Dollars ($3,000,000)
                  derived from its Mortgage Banking activities (as hereinafter
                  defined).

                  (ii)  One half (1/2) of the incentive bonus shall be payable
                        annually by DMC within 120 days following the end of the
                        preceding fiscal year, provided that such amount shall
                        only be payable if you shall have served as President to
                        DMC pursuant to this Agreement for the entire fiscal
                        year to which such payments relate. As used in this
                        Section 3, "Net Income" means the annual net income by
                        DMC and its subsidiaries after all taxes during the

                        accordance with generally accepted accounting principles
                        applied on a consistent basis throughout the periods
                        involved and as shown by DMC's audited financial
                        statements audited by its independent accountants
                        (hereinafter referred to as "GAAP"). As used in this
                        Section 3, "Mortgage Banking Activities, and all
                        expenses of DMC (including all taxes) shall be deemed to
                        be related to its Mortgage Banking Activities.

                  (iii) The remaining one-half (1/2) of the incentive bonus (the
                        "Deferred Bonus") shall be deferred pursuant to the
                        deferred compensation arrangement described in Exhibit A
                        hereto.

         (c)      You shall be entitled to participate in the other benefit
                  plans of DMC upon the terms and conditions on which such
                  benefits are made available to other employees of DMC. Nothing
                  herein shall obligate DMC to continue any existing benefit
                  plan or to establish any replacement benefit plan.

         (d)      You shall be entitled to reimbursement for reasonable travel
                  and entertainment expenses incurred in connection with the
                  rendering of your services hereunder. Nothing contained herein
                  shall authorize you to make any political contributions,
                  including but not limited to payments for dinners and
                  advertising in any political party program or any other
                  payment to any person which might be deemed a bribe, kickback
                  or otherwise and improper payment under corporate policy or
                  practice and no portion of the compensation payable hereunder
                  is for any such purpose.

         (e)      Payments under this Agreement shall be subject to reduction by
                  the amount of any applicable federal, Commonwealth, state or
                  municipal income, withholding, social security, state
                  disability insurance, or similar or other taxes or other items
                  which may be required or authorized to be deducted by law or
                  custom.

         (f)      No additional compensation shall be due to you for services
                  performed or offices held in any subsidiary, division,
                  affiliate, or venture of DMC or FFCC.

4.       MISCELLANEOUS PROVISIONS RELATING TO THE BONUS AND OTHER MATTERS

         (a)      Your acceptance of this Agreement will confirm that you
                  understand and agree that the granting of the incentive
                  compensation referred to in Section 3 (b) (the "incentive
<PAGE>   3

                                                                              3

                  compensation"), and any action thereunder, does not involve
                  any statement or representation of any kind by DMC as to its
                  business, affairs, earnings or assets, or as to the tax status
                  of the incentive compensation or the tax consequences of any
                  payment thereof, or otherwise. You further agree that any
                  action at any time taken by or on behalf of DMC or by its
                  directors or any committee thereof, which might or shall at
                  any time adversely affect you or the incentive compensation,
                  may be freely taken notwithstanding any such adverse effect
                  without your being thereby or otherwise entitled to any right
                  or claim against DMC, FFCC or any other person or party by
                  reason thereof.

         (b)      The incentive compensation is personal to you and is not
                  transferable or assignable either by your act or by operation
                  of law, and no assignee, trustee in bankruptcy, receiver or
                  other party whosoever shall have any right to demand any
                  incentive compensation or any other right with respect to it.
                  If, in the event of your death or incapacity, your legal
                  representative shall be entitled to demand the incentive
                  compensation under any of the provisions hereof then, unless
                  otherwise indicated by the context or otherwise required by
                  any term hereof, references to "you" shall apply to said
                  representative.

         (c)      If and when questions arise from time to time as to the
                  intent, meaning or application of any one or more of the
                  provisions hereof such questions will be decided by the Board
                  of Directors of DMC or any Committee appointed to consider
                  such matters, or, in the event DMC is merged into or
                  consolidated with any other corporation, by the Board of
                  Directors (or a Committee appointed by it) of the surviving or
                  resulting corporation, and the decision of such Board of
                  Directors or Committee, as the case may be, as to what is a
                  fair and equitable settlement of each such question or as to
                  what is a fair and proper interpretation of any provision
                  hereof or thereof, whatever the effect of such a decision may
                  be, beneficial or adverse, upon the incentive compensation,
                  shall be conclusive and binding and you hereby agree that the
                  incentive compensation is granted to and accepted by you
                  subject to such condition and understanding. You understand
                  that the incentive compensation is not held or set aside in
                  trust and (1) DMC may seek to retain, offset, attach or
                  similarly place a lien on such funds in circumstances where
                  you have been discharged for cause and shall be entitled to do
                  so for (x) malfeasance damaging to DMC, (y) conversion to you
                  of opportunity of DMC of FFCC, or (z) a violation of FFCC's
                  conflict of interest policy, in each case as determined in the
                  sole discretion of the Board of Directors, and (2) in the
                  event DMC is unable to make any payment under this Agreement
                  because of insolvency, bankruptcy or similar status or
                  proceedings, you will be treated as a general unsecured
                  creditor of DMC and may be entitled to no priority under
                  applicable law with respect to such payments.

5.       RESTRICTIONS ON COMPETITION

         During the term of this Agreement and for a period of one year after
         you cease to be an employee of DMC or an affiliate of DMC or FFCC, you
         will not, without the prior written consent of DMC, (a) accept
         employment or render service to any person, firm or corporation,
         directly or indirectly, in competition with DMC or FFCC, or any
         affiliate thereof for any purpose which would be competitive with the
         mortgage banking business within the Commonwealth of Puerto Rico or any
         other geographic area in which DMC or any affiliate of DMC or FFCC by
         which you were employed, conducted operations (the "Restricted Area")
         or any business by which you were employed within two years prior
         thereto (collectively, the "Restricted Businesses") or (b) directly or
         indirectly, enter into or in any manner take part in or lend your name,
         counsel or assistance to any venture, enterprise, business or endeavor,
         whether as proprietor, principal, investor, partner, director, officer,
         employee, consultant, adviser, agent, independent contractor or in any
         other capacity whatsoever for any purpose which would be competitive
         with the Restricted Businesses in the Restricted Area. An investment
         not exceeding 5% of the outstanding stock in any corporation regularly
         traded on any national securities exchange or in the over-the-counter
         market shall not be deemed to violate this provision, provided that you
         shall not render any services for such corporation.

6.       TERMINATION OF EMPLOYMENT

         (a)      Your employment hereunder may be terminated for dishonesty,
                  death, incapacity, or inability to perform the duties of your
                  employment on a daily basis, resulting from physical or mental
                  disability caused by illness, accident or otherwise or refusal
                  to perform the duties and responsibilities of your employment
                  hereunder, or breach of fidelity to DMC.

         (b)      At any time following a "Change in Control" of DMC, this
                  Agreement may be terminated by DMC or you on 30 days' written
                  notice to you or FFCC, as the case may be, such termination to
                  be effective as of the end of the calendar year during which
                  such notice is given. As used herein, a "Change in Control"
                  shall be deemed to have occurred at such time as any person
                  other than FFCC or an entity controlled by or under common
                  control with FFCC ceases to be the owner of at least 51% of
                  the outstanding voting securities of DMC.

         (c)      If at any time you shall voluntarily terminate your
                  employment, then this Agreement, except for Section 5 hereof,
                  shall terminate and all further obligations of FFCC hereunder
                  shall cease, provided that in any termination pursuant to

                  receive all compensation due to you pursuant to Section 3(a)
                  hereof (but not 3 (b) --(c)) for the calendar year in which
                  such date of termination occurs.

                  You agree that this Section 6 shall create no additional
                  rights in you to direct the operations of DMC.

7.       WAIVERS AND MODIFICATIONS

         No waiver by either party of any breach by the other of any provisions
         hereof shall be deemed to be a waiver of any later or other breach
         thereof, or as a waiver of any such or other provision of this
         Agreement. This Agreement sets forth all of the terms of the

8.       SEVERABILITY

         interpreted in such manner as to be effective under applicable law. In
         the event that any provision, or any portion of any provision, of this
         Agreement shall be held to be void and unenforceable, the remaining
         provisions of this Agreement, and the remaining portion of any
         provision found void or unenforceable in part only, shall continue in
         full force and effect.

         Name: Salomon Levis
         Title: Chairman of the Board and
         Chief Executive Officer

         Accepted and Agreed to as of the
         date first above set forth:

         /s/ Edison Velez

                                                                   EXHIBIT 10.01

                                MASTER AGREEMENT

         This Master Agreement (the "Agreement") is made and entered into as of
this 18th day of February, 2000 (the "Effective Date"), by and between Summus,
Ltd., a Delaware corporation ("Summus"), and High Speed Net Solutions, Inc., a
Florida corporation ("HSNS"):

         1.       Summus and HSNS have previously entered into a Marketing
                  License Agreement ("MLA") dated in February of 1999 and
                  certain Related Agreements. "Related Agreements" means
                  agreements between Summus and HSNS related to or incorporated
                  by the MLA and agreements based on either Summus' or HSNS's
                  rights and obligations under the MLA, including, but not
                  limited to, the Letter Agreement incorporated by the MLA and
                  any agreements relating to or arising from opportunities to
                  sell or license products or services to Samsung.

         2.       The MLA contemplated that HSNS will act as a reseller of
                  Summus products. The parties have concluded that it would be
                  to their mutual benefit, instead, for HSNS to primarily use
                  Summus products and services to conduct a service bureau
                  business and for HSNS and Summus to share revenues derived
                  from each party's business activity with Summus' products. As
                  a service bureau, HSNS will not act as a reseller of Summus'
                  products.

         3.       In order to enable the proposed service bureau business of
                  HSNS and proposed revenue sharing between the parties, Summus
                  and HSNS hereby agree to enter into the Software License
                  Agreement, Software Maintenance Agreement, and Revenue Sharing
                  Agreement attached to this Agreement as Exhibits A, B, and C
                  respectively (collectively, the "New Agreements"). Terms not
                  otherwise defined herein shall have the meanings specified in
                  the New Agreements.

         4.       Upon execution of the New Agreements, the MLA and the Related
                  Agreements shall terminate and have no further force or
                  effect. Neither party shall have any obligation of further
                  performance under the MLA or the Related Agreements.

         5.       "License Fee Credit" - shall mean the amount of One Million

         7.       "Annual Maintenance Fee Credit" - shall mean the amount of One
                  Hundred Fifty Thousand Dollars ($150,000) as a one-time credit

                  made under the MLA. The Annual Maintenance Fee Credit may be

                  Licensor by the Customer as a result of the Revenue Fee in the
                  Software License Agreement, Exhibit A. Such Customer Credit
                  may be used at the discretion of the Customer to pay any
                  charges due to Licensor in connection with the New Agreements.

                  Customer to be applied against purchase of other products
                  and/or services of Licensor. In the event that the Software
                  License Agreement is terminated by Customer for material
                  failure of Licensor to deliver (including the cure period of
                  60 days) the products as described in Exhibit A.1, the License
                  Fee Credit, Revenue Based Fee Credit, and Annual Maintenance
                  Fee Credit shall increase by 1.5% per month for up to twelve
                  (12) months or until such time as Customer selects other
                  products and/or services of Licensor to be paid through the
                  application of the Credit, whichever occurs first. Customer
                  and Licensor shall cooperate to select such other products or
                  services of Licensor promptly in order to apply the credits
                  without undue delay, but Customer shall not be required to
                  apply the credits against products and/or services that are
                  not needed or useful in Customer's business.

         10.      Licensor will provide to Customer additional resource support
                  through provision of ancillary services, in an approximate
                  fair market value of Two Hundred Fifty Thousand Dollars
                  ($250,000). The ancillary services may consist of, at the
                  discretion of Licensor, cash payments, credits against charges
                  due for services under the New Agreements, computer hardware,
                  third party software licenses, or other services requested by
                  Customer. Licensor shall provide the ancillary services
                  reasonably requested by Customer in prompt commercial fashion.
                  The total value of all ancillary services provided, whether
                  delivered in cash, services, or products, shall be deemed to
                  be an advance amount to be offset by payments due Customer
                  from Licensor under the Revenue Sharing Agreement and shall be
                  accounted for without interest or any other charges
                  whatsoever. To the extent any Customer Credit amounts are
                  available, Customer may at its sole discretion apply such
                  amounts to reduce the ancillary service advance amount total.

         11.      This Agreement shall be construed and enforced in accordance
                  with the laws of the State of North Carolina, but without
                  giving effect to its laws or rules relating to conflicts of
                  laws. In the event of any dispute or controversy arising under
                  or in connection with this Agreement or any New Agreement, the
                  dispute resolution procedures set forth in Exhibit A shall be
                  followed

         12.      Any dispute or controversy arising under or in connection with
                  this Agreement shall be settled in Wake County, North

         13.      This Agreement may be executed in one or more counterparts,
                  each of which shall be deemed an original, but all of which
                  together shall constitute one and the same instrument.

         14.      This Agreement and the New Agreements contain the full

                  of this Agreement; and there are no representations,
                  warranties, agreements or understandings other than those
