     This Employment Agreement ("Agreement") is made and entered into as of
the 15th day of August, 2000, by and between Gabriel Communications, Inc., a
Delaware corporation (the "Company"), and Gerard J. Howe ("Executive").

     WHEREAS, Executive desires to continue to be employed by the Company, and
the Company desires to continue to employ Executive, upon the terms and
conditions hereinafter set forth.

     NOW, THEREFORE, in consideration of the compensation and other benefits of
Executive's employment by the Company and the recitals, mutual covenants and
agreements hereinafter set forth, Executive and the Company agree as follows:

     1. Employment Services.

          (a) During the Employment Period (as defined below), the Company
agrees to employ Executive, and Executive agrees to serve the Company, in
Executive's present capacity as President-Strategic Initiatives  of the Company
or in another executive capacity with substantially equivalent
responsibilities. Executive will devote substantially his entire business time
and best efforts during the Employment Period to the performance of his duties,
as now or hereafter prescribed by the Company's By-Laws or assigned by the
Board of Directors of the Company (the "Board") or the Chief Executive Officer
of the Company, including service in his present offices or other offices with
the Company and its subsidiary and associated companies to which he is or
hereafter may be elected or appointed; provided, however, that without the
consent of Executive, Executive may not be required to regularly perform his
duties at any location that is more than twenty-five(25) miles from the present
principal executive offices of the Company.

          (b) Executive shall not, during the Employment Period, become or serve
as a director, officer, employee or member of any entity conducting, nor become
an owner of any substantial interest in any entity conducting, a business in
substantial competition with the Company's Business.

     2. Term of Employment. The term of this Employment Agreement (the
"Employment Period") shall be the three (3) year period from the date hereof to
and including August 15, 2003 (the "Initial Period"), and shall thereafter
continue from year to year (each an "Annual Extension"), unless sooner
terminated as provided in the second sentence of this Section 2 or in Section 4
hereof. Unless sooner terminated as provided in Section 4 hereof, the Employment
Period may be terminated by either the Company or Executive, at the end of the
Initial Period or an Annual Extension, if a written notice of nonrenewal is
delivered to the other party at least six (6) months prior to the end of such
Initial Period or Annual Extension, as the case may be.

     3. Compensation and Benefits.

<PAGE>   2

          (a) Annual Base Salary. During the Employment Period, the Company
shall pay Executive as compensation for his services an annual base salary in an
amount determined by the Compensation Committee of the Board. Such annual base
salary shall be at the annual rate of not less than Two Hundred Thousand Dollars
($200,000) from the Effective Date through December 31, 2000. Executive's annual
base salary rate shall be reviewed at least annually for increase in the
discretion of the Compensation Committee; Executive's annual base salary rate
shall not be subject to decrease at any time during the Employment Period.
Executive's base salary shall be payable in accordance with the Company's usual
practices.

          (b) Annual Bonus. During the Employment Period, Executive shall be
eligible for an annual bonus under a bonus program to be established by the
Compensation Committee of the Board and approved by the Board. Under the bonus
program, Executive's annual bonus will be tied to performance criteria and
Executive is expected to be eligible for a bonus of forty to fifty percent
(40-50%) of his annual base salary.

          (c) Benefits. During the Employment Period, Executive shall also (i)
be eligible to participate in all benefit programs from time to time maintained
by the Company for the benefit of its most senior executives including without
limitation, its group medical, dental and term life insurance coverages, 401 (k)
Plan and the Company's 1998 Stock Incentive Plan ("Stock Plan"), in each case on
and subject to the terms and conditions of each of such programs as such
programs apply to the Company's most senior executives, and (ii) be entitled to
four (4) weeks of paid vacation per year.

     4. Termination of Employment. Prior to the expiration of the Employment
Period, this Agreement and Executive's employment may be terminated as follows:

          (a) Automatically upon Executive's death.

          (b) By the Company, upon thirty (30) day's prior written notice to
Executive, in the event the Board believes that Executive, by reason of physical
or mental illness, is unable to perform a material portion of the services
required of Executive hereunder for a continuous one-hundred thirty-five (135)
day period; in the event of a disagreement concerning the existence of any such
disability (in which event any such termination shall not become effective until
such disagreement shall have been resolved), the matter shall be resolved by a
disinterested licensed physician chosen by the Company (such physician to be
located within 50 miles of Executive's principal residence) and otherwise
reasonably satisfactory to the Executive or his legal representative.

          (c) By the Company, for "Good Cause." "Good Cause" shall mean:

               (1) The willful and continued failure of Executive to
     substantially perform material duties assigned to Executive in accordance
     with Section 1(a) hereof (other than any such failure resulting from
     incapacity due to physical or mental illness);

               (2) A material breach of Section 1(b) of this Agreement by
     Executive; or

                                       2
<PAGE>   3

               (3) Executive's commission of fraud or willful conduct which
significantly harms the Company or its subsidiaries or which significantly
impairs Executive's ability to perform his duties.

For purposes of this definition, no act, or failure to act, shall be deemed
"willful" unless done, or omitted to be done, by the Executive not in good faith
and without reasonable belief that his action or omission was in the best
interest of the Company.

Unless the Executive has been convicted of a felony, no termination for Good
Cause shall take effect unless the following provisions of this paragraph shall
have been complied with. The Board shall give the Executive written notice of
its intention to terminate him for Good Cause, such notice (i) to state in
detail the particular circumstances that constitute the grounds on which the
proposed termination for Good Cause is based and (ii) to be given within four
months of the Board learning of such circumstances. The Executive shall have
twenty days, after receiving such special notice, to cure such grounds, to the
extent such cure is possible. If he fails to cure such grounds to the Board's
satisfaction, the Executive shall then be entitled to a hearing by the Board or
a committee thereof, during which he may, at his election, be represented by
counsel. Such hearing shall be held within thirty days of his receiving such
special notice, provided he requests a hearing within fifteen days of receiving
the notice. If the Board gives written notice to the Executive within five days
following such hearing confirming that, in the good faith judgment of a majority
of the Board, Good Cause for terminating him on the basis set forth in the
original notice exists, he shall thereupon be terminated for Good Cause.

          (d) By the Company, without Good Cause, upon seven (7) days prior
written notice to Executive. A termination without Good Cause shall be deemed to
exist upon any termination of Executive by the Company other than as set forth
in Sections 4(a), (b), (c) or (f) or upon delivery by the Company of a notice of
non-extension pursuant to Section 2.

          (e) By Executive, immediately upon his determination that "Good
Reason" for termination exists. "Good Reason" shall be deemed to exist if:

               (1) Executive's titles, duties, authorities or responsibilities
     are materially reduced or modified without Executive's consent, in his sole
     discretion, from those specified herein; or

               (2) A change in the location of the Company's executive offices
     to a location that is greater than 25 miles from its present location.

          (f) By the Company, upon a Change of Control (as defined in the Stock
     Plan).

          (g) By Executive, upon ninety(90) days prior written notice to the
     Company, for serious personal reasons that Executive believes makes it
     inadvisable for him to continue to perform his services hereunder.

     5. Effect of Termination of Employment. Upon termination of Executive's
employment and this Agreement, the rights and obligations of the parties
pursuant to Sections 7 through 14 and Section 16 shall be unaffected, but all
other rights and obligations of the parties hereunder shall cease, except:

          (a) If this Agreement is terminated pursuant to Section 4(a) or (b),
Executive (or his estate) shall receive his annual base salary and benefits (as

occurs and for a period of twelve (12) calendar months thereafter (according to
the same payroll practices in effect at the time of termination). In addition,
Executive (or his estate) shall receive a lump sum payment, within ten days of
any such termination, equal to the maximum bonus for which Executive was
eligible in the year in which such termination occurs, plus payment of accrued
but untaken vacation for the portion of the year in which such termination
occurs. Notwithstanding the terms of the Stock Plan and any Awards (as defined
in the Stock Plan) granted to Executive thereunder, all such Awards outstanding
immediately prior to such termination shall immediately become exercisable.

          (b) If this Agreement is terminated pursuant to Section 4(c) or 4(g),
Executive shall receive his annual base salary and benefits (including his
vested Awards under the Stock Plan) accrued through the date of such termination
of employment. Any unvested Awards under the terms of the Stock Plan shall be
forfeited.

          (c) If this Agreement is terminated pursuant to Section 4(d),
Executive shall receive his annual base salary for the remainder of the calendar
year in which such termination occurs and benefits (as applicable) for the
remainder of the Initial Period or the applicable Annual Extension, as the case
may be. In addition, Executive shall receive a lump sum payment equal to two
times his then current annual base salary, plus payment of accrued but untaken
vacation for the portion of the year in which such termination occurs.
Notwithstanding the terms of the Stock Plan and any Awards granted to Executive
thereunder, all such Awards outstanding immediately prior to such termination
shall immediately become exercisable.

          (d) If this Agreement is terminated pursuant to Section 4(e),
Executive shall receive his annual base salary and benefits (as applicable) for
a period of twelve (12) calendar months after the date of such termination.

forfeited.

          (e) If this Agreement is terminated pursuant to Section 4(f),
Executive shall receive his annual base salary for the remainder of the calendar
year in which such termination occurs and benefits (as applicable) for the
remainder of the Initial Period or the applicable Annual Extension, as the case
may be. In addition, Executive shall receive a lump sum payment equal to three
times his then current annual base salary, plus three times the maximum bonus
for which Executive was eligible in the year in which such termination occurs.
Notwithstanding the terms of the Stock Plan and any Awards granted to Executive
thereunder, all such Awards outstanding immediately prior to such termination
shall immediately become exercisable.

                                       4
<PAGE>   5

          (f) All shares of stock, options and warrants held by Executive at the
time of termination shall remain subject to the terms of the Stock Plan and the
agreements pursuant to which they were issued.

     6. Provisions Relating to Taxation of Payments.

          (a) Gross-up Payment. Anything in this Agreement to the contrary
notwithstanding, in the event it shall be determined that any payment or
distribution by the Company to or for the benefit of Executive, whether paid or
payable or distributed or distributable pursuant to the terms of this Agreement
or otherwise would be subject to the excise tax imposed by Section 4999 of the
Internal Revenue Code of 1986, as amended, or any interest or penalties with
respect to such excise tax (such excise tax, together with any such interest and
penalties, are hereinafter collectively referred to as the "Excise Tax"), then
Executive shall be entitled to receive an additional payment (a "Gross-Up
Payment") in an amount such that after payment by Executive of all taxes
(including any interest or penalties imposed with respect to such taxes),
including any Excise Tax, imposed upon the Gross-Up Payment, Executive retains
an amount of the Gross-Up Payment equal to the Excise Tax imposed upon such
payment or distribution.

          (b) Determination of Gross-Up. Subject to the provisions of paragraph
(c) of this Section 6, all determinations required to be made under this Section
6, including whether a Gross-Up Payment is required and the amount of such
Gross-Up Payment, shall be made by an accounting firm satisfactory to the
Company and Executive ("Accounting Firm"). The Accounting Firm shall make such
determination and provide detailed supporting calculations to both the Company
and Executive within fifteen (15) business days after it is requested to do so.
The initial Gross-Up Payment, if any, as determined pursuant to this paragraph
(b) of this Section 6, shall be paid to Executive within five (5) business days
after the Company's receipt of the Accounting Firm's determination. If the
Accounting Firm determines that no Excise Tax is payable by the Executive, it
shall furnish the Executive with a written opinion that he has legal authority
satisfying the criteria set forth in Treasury Regulation Section 1.6661-3 or
similar successor provisions not to report any Excise Tax on his federal income
tax return. Any determination by the Accounting Firm shall be binding upon the
Company and Executive.

          (c) Dispute of Tax Claim. Executive shall notify the Company in
writing of any proposed assessment or proposed adjustment by the Internal
Revenue Service ("IRS") pursuant to an audit of Executive's federal income tax
return or otherwise, that, if successful, would require the payment by the
Company of a Gross-Up Payment (hereinafter referred to as a "Claim"). Such
notice shall be given as soon as practicable but no later than ten (10) business
days after the earlier of (i) the receipt by Executive of a written notice of
proposed adjustment from the IRS or (ii) the receipt by Executive of a statutory
notice of deficiency. Such notice by Executive to the Company shall include (i)
notice of the amount of the proposed assessment or proposed adjustment which
relates to the Claim and the taxable year or years in which the Claim arises,
(ii) the general nature of the Claim and (iii) all relevant written reports of
the examining agent relating to the Claim. Within thirty (30) days of (i) the
receipt by Executive of a final assessment or (ii) the execution by Executive
and the IRS of a closing agreement, with respect to any tax year of Executive in
which a Claim has been raised, pursuant to which Executive is required to pay
any amount with respect to

                                       5
<PAGE>   6

the Claim, Executive shall provide the Company and the Accounting Firm with a
copy of such assessment or agreement, together with supporting documents
sufficient to determine the amount of such tax liability that was attributable
to the Claim. The Accounting Firm shall determine the amount Gross-Up Payment
under this Agreement due to such tax liability and the Company will make such
Gross-Up Payment to Executive within five (5) business days after its receipt of
such determination.

     7. Withholding. All compensation paid to Executive shall be subject to
customary withholding taxes and other employment taxes as required with respect
thereto.

     8. Non-Waiver of Rights. The failure of either party to enforce at any time
any of the provisions of this Agreement or to require at any time performance by
the other party of any of the provisions hereof shall in no way be construed to
be a waiver of such provisions or to affect either the validity of this
Agreement, or any part hereof, or the right of either party thereafter to
enforce each and every provision in accordance with the terms of this Agreement.

     9. Severability and Interpretation. In the event of a conflict between the
terms of this Agreement and any of the definitions or provisions in the Stock
Plan, the terms of this Agreement shall prevail. Whenever possible, each
provision of this Agreement and any portion hereof shall be interpreted in such
a manner as to be effective and valid under applicable law, rules and
regulations. If any convenant or other provision of this Agreement (or portion
thereof) shall be held to be invalid, illegal, or incapable of being enforced,
by reason of any rule of law, rule, regulation, administrative order, judicial
decision or public policy, all other conditions and provisions of this Agreement
shall, nevertheless, remain in full force and effect, and no covenant or
provision shall be deemed dependent upon any other convenant or provision (or
portion) unless so expressed herein. The parties hereto desire and consent that
the court or other body making such determination shall, to the extent necessary
to avoid any unenforceability, so reform such covenant or other provision or
portions of this Agreement to the minimum extent necessary so as to render the
same enforceable in accordance with the intent herein expressed.

     10. Entire Agreement. This Agreement represents the entire and integrated
Employment Agreement between Executive and the Company and supersedes all prior
negotiations, representations and agreements, either written or oral, with
respect thereto.

     11. Notice. All notices and other communications hereunder shall be in
writing and shall be given by hand delivery to the other party, by registered or
certified mail, return receipt requested, postage prepaid, or by overnight
courier, addressed as set forth in this Section 11 or to such other address as
may hereafter be notified by such party to the other party. Notices and
communications shall be effective at the time they are given in the foregoing
manner (provided that notice by mail shall be deemed given three business days
after posting).

               (3) Executive's commission of fraud or willful conduct which
significantly harms the Company or its subsidiaries or which significantly
impairs Executive's ability to perform his duties.

For purposes of this definition, no act, or failure to act, shall be deemed
"willful" unless done, or omitted to be done, by the Executive not in good faith
and without reasonable belief that his action or omission was in the best
interest of the Company.

Unless the Executive has been convicted of a felony, no termination for Good
Cause shall take effect unless the following provisions of this paragraph shall

months of the Board learning of such circumstances. The Executive shall have
twenty days, after receiving such special notice, to cure such grounds, to the
extent such cure is possible. If he fails to cure such grounds to the Board's
satisfaction, the Executive shall then be entitled to a hearing by the Board or
a committee thereof, during which he may, at his election, be represented by
counsel. Such hearing shall be held within thirty days of his receiving such
special notice, provided he requests a hearing within fifteen days of receiving
the notice. If the Board gives written notice to the Executive within five days
following such hearing confirming that, in the good faith judgment of a majority
of the Board, Good Cause for terminating him on the basis set forth in the
original notice exists, he shall thereupon be terminated for Good Cause.

          (d) By the Company, without Good Cause, upon seven (7) days prior
written notice to Executive. A termination without Good Cause shall be deemed to
exist upon any termination of Executive by the Company other than as set forth
in Sections 4(a), (b), (c) or (f) or upon delivery by the Company of a notice of
non-extension pursuant to Section 2.

          (e) By Executive, immediately upon his determination that "Good
Reason" for termination exists. "Good Reason" shall be deemed to exist if:

               (1) Executive's titles, duties, authorities or responsibilities
     are materially reduced or modified without Executive's consent, in his sole
     discretion, from those specified herein; or

               (2) A change in the location of the Company's executive offices
     to a location that is greater than 25 miles from its present location.

          (f) By the Company, upon a Change of Control (as defined in the Stock
     Plan).

          (g) By Executive, upon ninety(90) days prior written notice to the
     Company, for serious personal reasons that Executive believes makes it
     inadvisable for him to continue to perform his services hereunder.

Executive (or his estate) shall receive a lump sum payment, within ten days of
any such termination, equal to the maximum bonus for which Executive was
eligible in the year in which such termination occurs, plus payment of accrued
but untaken vacation for the portion of the year in which such termination
occurs. Notwithstanding the terms of the Stock Plan and any Awards (as defined
in the Stock Plan) granted to Executive thereunder, all such Awards outstanding
immediately prior to such termination shall immediately become exercisable.

          (b) If this Agreement is terminated pursuant to Section 4(c) or 4(g),
Executive shall receive his annual base salary and benefits (including his
vested Awards under the Stock Plan) accrued through the date of such termination
of employment. Any unvested Awards under the terms of the Stock Plan shall be
forfeited.

          (c) If this Agreement is terminated pursuant to Section 4(d),
Executive shall receive his annual base salary for the remainder of the calendar
year in which such termination occurs and benefits (as applicable) for the
remainder of the Initial Period or the applicable Annual Extension, as the case

times his then current annual base salary, plus payment of accrued but untaken
vacation for the portion of the year in which such termination occurs.
Notwithstanding the terms of the Stock Plan and any Awards granted to Executive
thereunder, all such Awards outstanding immediately prior to such termination
shall immediately become exercisable.

          (f) All shares of stock, options and warrants held by Executive at the
time of termination shall remain subject to the terms of the Stock Plan and the
agreements pursuant to which they were issued.

     6. Provisions Relating to Taxation of Payments.

          (a) Gross-up Payment. Anything in this Agreement to the contrary
notwithstanding, in the event it shall be determined that any payment or
distribution by the Company to or for the benefit of Executive, whether paid or
payable or distributed or distributable pursuant to the terms of this Agreement
or otherwise would be subject to the excise tax imposed by Section 4999 of the
Internal Revenue Code of 1986, as amended, or any interest or penalties with
respect to such excise tax (such excise tax, together with any such interest and
penalties, are hereinafter collectively referred to as the "Excise Tax"), then
Executive shall be entitled to receive an additional payment (a "Gross-Up
Payment") in an amount such that after payment by Executive of all taxes
(including any interest or penalties imposed with respect to such taxes),
including any Excise Tax, imposed upon the Gross-Up Payment, Executive retains
an amount of the Gross-Up Payment equal to the Excise Tax imposed upon such
payment or distribution.

          (b) Determination of Gross-Up. Subject to the provisions of paragraph
(c) of this Section 6, all determinations required to be made under this Section
6, including whether a Gross-Up Payment is required and the amount of such
Gross-Up Payment, shall be made by an accounting firm satisfactory to the
Company and Executive ("Accounting Firm"). The Accounting Firm shall make such
determination and provide detailed supporting calculations to both the Company
and Executive within fifteen (15) business days after it is requested to do so.
The initial Gross-Up Payment, if any, as determined pursuant to this paragraph
(b) of this Section 6, shall be paid to Executive within five (5) business days
after the Company's receipt of the Accounting Firm's determination. If the
Accounting Firm determines that no Excise Tax is payable by the Executive, it
shall furnish the Executive with a written opinion that he has legal authority
satisfying the criteria set forth in Treasury Regulation Section 1.6661-3 or
similar successor provisions not to report any Excise Tax on his federal income
tax return. Any determination by the Accounting Firm shall be binding upon the
Company and Executive.

          (c) Dispute of Tax Claim. Executive shall notify the Company in
writing of any proposed assessment or proposed adjustment by the Internal
Revenue Service ("IRS") pursuant to an audit of Executive's federal income tax
return or otherwise, that, if successful, would require the payment by the
Company of a Gross-Up Payment (hereinafter referred to as a "Claim"). Such
notice shall be given as soon as practicable but no later than ten (10) business
days after the earlier of (i) the receipt by Executive of a written notice of
proposed adjustment from the IRS or (ii) the receipt by Executive of a statutory
notice of deficiency. Such notice by Executive to the Company shall include (i)
notice of the amount of the proposed assessment or proposed adjustment which
relates to the Claim and the taxable year or years in which the Claim arises,
(ii) the general nature of the Claim and (iii) all relevant written reports of
the examining agent relating to the Claim. Within thirty (30) days of (i) the
receipt by Executive of a final assessment or (ii) the execution by Executive
and the IRS of a closing agreement, with respect to any tax year of Executive in
which a Claim has been raised, pursuant to which Executive is required to pay
any amount with respect to

                                       5
<PAGE>   6

the Claim, Executive shall provide the Company and the Accounting Firm with a
copy of such assessment or agreement, together with supporting documents
sufficient to determine the amount of such tax liability that was attributable
to the Claim. The Accounting Firm shall determine the amount Gross-Up Payment
under this Agreement due to such tax liability and the Company will make such
Gross-Up Payment to Executive within five (5) business days after its receipt of
such determination.

     7. Withholding. All compensation paid to Executive shall be subject to
customary withholding taxes and other employment taxes as required with respect
thereto.

     8. Non-Waiver of Rights. The failure of either party to enforce at any time
any of the provisions of this Agreement or to require at any time performance by
the other party of any of the provisions hereof shall in no way be construed to
be a waiver of such provisions or to affect either the validity of this
Agreement, or any part hereof, or the right of either party thereafter to
enforce each and every provision in accordance with the terms of this Agreement.

     9. Severability and Interpretation. In the event of a conflict between the
terms of this Agreement and any of the definitions or provisions in the Stock
Plan, the terms of this Agreement shall prevail. Whenever possible, each
provision of this Agreement and any portion hereof shall be interpreted in such
a manner as to be effective and valid under applicable law, rules and
regulations. If any convenant or other provision of this Agreement (or portion
thereof) shall be held to be invalid, illegal, or incapable of being enforced,
by reason of any rule of law, rule, regulation, administrative order, judicial
decision or public policy, all other conditions and provisions of this Agreement
shall, nevertheless, remain in full force and effect, and no covenant or
provision shall be deemed dependent upon any other convenant or provision (or
portion) unless so expressed herein. The parties hereto desire and consent that
the court or other body making such determination shall, to the extent necessary
to avoid any unenforceability, so reform such covenant or other provision or
portions of this Agreement to the minimum extent necessary so as to render the
same enforceable in accordance with the intent herein expressed.

     10. Entire Agreement. This Agreement represents the entire and integrated
Employment Agreement between Executive and the Company and supersedes all prior
negotiations, representations and agreements, either written or oral, with
respect thereto.

     11. Notice. All notices and other communications hereunder shall be in
writing and shall be given by hand delivery to the other party, by registered or
certified mail, return receipt requested, postage prepaid, or by overnight
courier, addressed as set forth in this Section 11 or to such other address as
may hereafter be notified by such party to the other party. Notices and
communications shall be effective at the time they are given in the foregoing
manner (provided that notice by mail shall be deemed given three business days
after posting).
